[PMID: 38641062 DOI: 10.1016/j.hansur.2024.101698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Revised: 03/28/2024] [Accepted: 04/02/2024] [Indexed: 04/21/2024]
Abstract
BACKGROUND The most common symptom and reason patients seek treatment for carpal tunnel syndrome is lack of sleep. Our purpose was to determine how much sleep-related symptoms of carpal tunnel syndrome improve after carpal tunnel release using validated patient-reported outcome measures (PROMs) and objective sleep data as primary measures of interest. METHODS A PRISMA-guided literature search was conducted using Ovid MEDLINE, PubMed, Cochrane, and ClinicalTrials.gov. Only interventional clinical trials that examined primary outcome measures of interest were included. Patient-reported outcome measures underwent meta-analysis to determine how much scores improved following carpal tunnel release. RESULTS The Pittsburgh Sleep Quality Index improved significantly after carpal tunnel release, by 4.43 points and 6.02 points at 1-3 and 6-12 months postoperatively, respectively, and continued to improve up to 2 years. Improvement on the Insomnia Severity Index after carpal tunnel release was also significant, with improvement up to 1 year postoperatively, by 8.54 points and 9.05 points at 1-3 and 6-12 months, respectively. Insomnia Severity Index scores improved significantly after splinting as well. CONCLUSIONS The present meta-analysis determined to what extent patients can expect their sleep to improve after operative and non-operative intervention, as measured by various patient-reported outcome measures that assess sleep. The Pittsburgh Sleep Quality Index and Insomnia Severity Index correlated very well between studies and across hundreds of patients with carpal tunnel syndrome. Data are lacking to define the minimal clinically important difference and assess whether patients achieve a minimal clinically important difference for sleep questionnaires; more information on this topic is needed.

Abstract
Carpal tunnel syndrome (CTS) is the most common nerve entrapment disorder worldwide. The epidemiology and risk factors, including family burden, for developing CTS are multi-factorial. Despite much research, its intricate pathophysiological mechanism(s) are not fully understood. An underlying subclinical neuropathy may indicate an increased susceptibility to developing CTS. Although surgery is often performed for CTS, clear international guidelines to indicate when to perform non-surgical or surgical treatment, based on stage and severity of CTS, remain to be elucidated. Neurophysiological examination, using electrophysiology or ultrasonography, performed in certain circumstances, should correlate with the history and findings in clinical examination of the person with CTS. History and clinical examination are particularly relevant globally owing to lack of other equipment. Various instruments are used to assess CTS and treatment outcomes as well as the effect of the disorder on quality of life. The surgical treatment options of CTS - open or endoscopic - offer an effective solution to mitigate functional impairments and pain. However, there are risks of post-operative persistent or recurrent symptoms, requiring meticulous diagnostic re-evaluation before any additional surgery. Health-care professionals should have increased awareness about CTS and all its implications. Future considerations of CTS include use of linked national registries to understand risk factors, explore possible screening methods, and evaluate diagnosis and treatment with a broader perspective beyond surgery, including psychological well-being.

Abstract
Carpal tunnel syndrome (CTS) occurs more often among individuals with diabetes. The aim of this retrospective observational registry study was to examine whether individuals with diabetes and CTS are treated surgically to the same extent as individuals with CTS but without diabetes. Data on CTS diagnosis and surgery were collected from the Skåne Healthcare Register (SHR). A total of 35,105 individuals (age ≥ 18 years) diagnosed with CTS from 2004-2019 were included. Data were matched to the Swedish National Diabetes Register (NDR. Cox regression models were used to calculate the risk of the use of surgical treatment. Of the 35,105 included individuals with a CTS diagnosis, 17,662 (50%) were treated surgically, and 4,966 (14%) had diabetes. A higher number of individuals with diabetes were treated surgically (2,935/4,966, 59%) than individuals without diabetes (14,727/30,139, 49%). In the Cox regression model, diabetes remained a significant risk factor for surgical treatment (PR 1.14 (95% CI 1.11-1.17)). Individuals with type 1 diabetes were more frequently treated surgically (490/757, 65%) than individuals with type 2 diabetes (2,445/4,209, 58%). There was no difference between the sexes and their treatment. The duration of diabetes was also a risk factor for surgical treatment in diabetes type 2, but high HbA1c levels were not. Individuals with diabetes are more likely to be treated surgically for CTS than individuals without diabetes. Individuals with type 1 diabetes are more likely to be treated surgically for CTS than individuals with type 2 diabetes.

Abstract
<b><br>Introduction:</b> The results of some studies show that predictors of less favourable outcomes of surgery for carpal tunnel syndrome might include the presence of comorbidities, such as diabetes and thyroid gland diseases. The role of these factors has not been clearly determined, but in most trials the patients burdened with comorbidities conducive to CTS are excluded from the analysis.</br> <b><br>Aim:</b> The aim of this study was to investigate the effect of concomitant diseases on the clinical profile and outcomes of surgery for carpal tunnel syndrome.</br> <b><br>Material and methods:</b> The study group consisted of 1117 patients - 909 women (81%) and 208 men (19%) - at a mean age of 63 years. A total of 972 patients (87%) declared having at least one comorbidity, whereas 145 patients (13%) declared no comorbidities. The measurements were performed preoperatively and at 6 months postoperatively; they included pain intensity, total grip and key-pinch strength, digital sensibility and hand function with Levine's questionnaire.</br> <b><br>Results:</b> At baseline, the patients with comorbidities had significantly worse digital sensiblility, weaker total grip strength and greater functional impairment of the hand, but only grip strength reached the minimal important difference (3.5 kg). Carpal tunnel release resulted in significant improvement in the tested variables for all patients, although the outcomes at 6 months were less favourable for those with comorbidities with regard to digital sensiblility, total grip and pinch strength and function of the hand. All these differences were statistically significant, but only grip strength reached the minimal important difference (2.9 kg).</br> <b><br>Conclusion:</b> The results of this study show that comorbidities in patients suffering from CTS had a statistically and clinically significant negative effect only on the total grip strength pre- and postoperatively, and no significant effect on the outcome of surgery, which was satisfactory in all patients.</br>.

Clin Neurol Neurosurg 2023; 231:107800. [PMID: 37270905 DOI: 10.1016/j.clineuro.2023.107800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2023] [Revised: 05/20/2023] [Accepted: 05/22/2023] [Indexed: 06/06/2023]
Abstract
BACKGROUND Carpal tunnel release outcomes in diabetic and non-diabetic patients are conflicting, possibly due to lack of differentiating patients with axonal neuropathy and those without axonal neuropathy. MATERIALS AND METHODS Sixty-five diabetic and 106 non-diabetic patients who failed conservative treatment and then underwent carpal tunnel release from 2015 to 2022 were selected from a hand surgeon's patient database. Diagnosis was established with parameters established with the CTS-6 Evaluation Tool, and electrodiagnosis when indicated. Patient outcomes were evaluated using preoperative and postoperative Disabilities of Arm Shoulder and Hand (DASH), Brief Pain Inventory (BPI), Boston Carpal Tunnel Questionnaire, Numeric Pain Scale, and Wong-Baker Pain Scale. Postoperative evaluations were taken 6 months to a year post-surgery. Skin biopsies for nerve fiber density and morphology were taken from 50 diabetic patients. Another 50 were taken from non-diabetic patients with carpal tunnel syndrome and served as controls. Biopsy-proven axonal neuropathy was used as a confounding variable in the assessment of diabetic patients' recovery RESULTS: When comparing diabetics with biopsy-proven axonal neuropathy to diabetics without axonal neuropathy, the recovery outcomes are increasingly better for diabetics without neuropathy. Diabetics with biopsy-proven neuropathy have an improvement in recovery outcomes as well; however, not to the level of non-diabetics. CONCLUSION Patients with increased scale scores or clinical suspicion for axonal neuropathy can be offered the option of undergoing a biopsy, and counseled about the risks for increased time to meet outcomes comparable to non-diabetics and diabetics without axonal neuropathy.

Abstract
PURPOSE The aim of this study was to review the literature to determine the prevalence of cold sensitivity in upper extremity nerve compression syndromes and the impact of treating nerve compression syndromes on cold sensitivity. METHODS Following a standardized scoping review protocol, this study included interventional and observational study designs assessing patients with cold sensitivity and upper extremity nerve compression syndromes. Review articles, case reports, and small case series (n < 5) were excluded. The abstracts and eligible full texts were screened by 2 independent reviewers. Data were extracted and reported according to PRISMA extension for scoping reviews statement. RESULTS Three databases were searched (Ovid MEDLINE, Ovid EMBASE, and CINAHL on EBSCO); 274 references were reviewed. Fifteen studies from the database search and 8 studies from the reference search were eligible for this review (n = 23). Two interventional and 21 observational studies were identified. The most common method for assessing cold sensitivity was cold pain threshold testing (n = 12), followed by subjective patient reporting (n = 4). The Cold Intolerance Symptom Severity questionnaire was the most common validated patient-reported outcome questionnaire used in the studies (n = 3). Cold sensitivity was most commonly reported in carpal tunnel syndrome (96% of the studies). The prevalence of cold sensitivity in nerve compression syndromes ranged from 20% to 69%. Nerve decompression improved the severity of cold sensitivity in 5 of 6 studies where cold sensitivity was studied. CONCLUSIONS There is heterogenicity in the studies assessing cold sensitivity in nerve compression syndromes. Despite moderate prevalence in patients with carpal tunnel syndrome, cold sensitivity is understudied. Within the limitations of eligible studies reviewed, surgical decompression improved the severity of cold sensitivity in some studies. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
Abstract
Background Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. Studies have shown that results of CTS surgery are poorer in patients with diabetes. In this study, the effect of platelet-rich plasma (PRP) on nerve regeneration was investigated through clinical and electromyographic findings in patients with diabetes who underwent CTS surgery.
Methods A retrospective analysis of 20 patients with diabetes who had surgically decompressed CTS was conducted. Patients were divided into two groups. The study group received PRP treatment following surgery. The control group did not receive any treatment. Patients were assessed using electromyography and the Boston Carpal Tunnel Syndrome Questionnaire preoperatively as well as postoperatively at 3-month, 6-month, and 1-year follow-ups visits.
Results There was a decrease in complaints and an improvement in sensory and motor examinations in both groups. The Boston Carpal Tunnel Syndrome Questionnaire scores did not show any statistically significant differences between the two groups. However, electromyographic findings showed that there were statistical differences between preoperative and postoperative (3 months, 6 months, and 1 year) results in both groups. When the two groups were compared using preoperative and postoperative (3 months, 6 months, and 1 year) electromyographic values, no statistically significant differences were seen.
Conclusion Single injections of PRP did not have a significant impact on median nerve regeneration following CTS surgery in patients with diabetes. The effectiveness of multiple PRP injections can be investigated in patients with diabetes in future studies.

Abstract
To investigate self-reported cold sensitivity and functional disability after a repaired digital nerve injury. We identified 3204 individuals operated with digital nerve repair in the Swedish national quality registry for hand surgery (HAKIR). Patient-reported symptoms, including cold sensitivity and perceived disability, were examined using two questionnaires (HQ-8 and QuickDASH), three and 12 months postoperatively. Patients with diabetes (n = 48; 3%) were identified in the Swedish National Diabetes Register (NDR). Cold sensitivity (scored 0–100) was the most prominent symptom among 1553 included individuals (998 men, 555 women; median age 41 [IQR 27–54] years). In the regression analysis, flexor tendon injury, hand fracture and injury to multiple structures predicted worsened cold sensitivity (6.9, 15.5 and 25.0 points; p = 0.005, 0.046 and < 0.001) at 12 months. Individuals with moderate (30–70) and severe (> 70) cold sensitivity had higher QuickDASH scores at three and 12 months postoperatively than individuals with mild cold sensitivity (6.0 and 5.5; 19.8 and 21.0 points; p = 0.001). Flexor tendon injury, injuries to multiple structures and diabetes had significant effect on QuickDASH scores at three, but not at 12, months postoperatively. Cold sensitivity is common after a digital nerve repair and impacts self-reported disability. A concomitant injury, particularly multiple injuries, predicts postoperative cold sensitivity.

Abstract
Carpal tunnel syndrome (CTS) is the most common compression neuropathy in the general population and is frequently encountered among individuals with type 1 and 2 diabetes. The reason(s) why a peripheral nerve trunk in individuals with diabetes is more susceptible to nerve compression is still not completely clarified, but both biochemical and structural changes in the peripheral nerve are probably implicated. In particular, individuals with neuropathy, irrespective of aetiology, have a higher risk of peripheral nerve compression disorders, as reflected among individuals with diabetic neuropathy. Diagnosis of CTS in individuals with diabetes should be carefully evaluated; detailed case history, thorough clinical examination, and electrophysiological examination is recommended. Individuals with diabetes and CTS benefit from surgery to the same extent as otherwise healthy individuals with CTS. In the present review, we describe pathophysiological aspects of the nerve compression disorder CTS in relation to diabetes, current data contributing to the explanation of the increased risk for CTS in individuals with diabetes, as well as diagnostic methods, treatment options, and prognosis of CTS in diabetes.

Abstract
PURPOSE To evaluate the association of diabetes and perioperative hemoglobin A1C (HgA1C) value with postoperative wound healing complications following carpal tunnel release (CTR) and trigger finger release (TFR). METHODS A retrospective review of diabetic patients who underwent CTR and/or TFR between 2014 and 2018 was performed. Hemoglobin A1C value within 90 days of surgery was recorded for all diabetic patients. A nondiabetic comparison group was selected from within the same study period in an approximately 1:1 procedural ratio, although direct matching was not performed. A chart review was used to examine postoperative wound healing complications, such as wound infection, wound dehiscence, or delayed wound healing. RESULTS Two hundred sixty-two diabetic patients and 259 nondiabetic patients underwent 335 and 337 CTR and/or TFR procedures, respectively. There were 36 wound complications in the diabetic group and 9 complications in the nondiabetic group. Logistic regression analysis demonstrated an increased association of wound healing complications with diabetic patients compared to nondiabetic patients. Additionally, an increased association was demonstrated among diabetic patients with an HgA1C value above 6.5% compared with those with an HgA1C value below 6.5%. CONCLUSIONS Compared with nondiabetic controls, diabetic patients have increased associated risk of postoperative wound healing complications following CTR and/or TFR. This increased association was further demonstrated among diabetic patients with elevated perioperative HgA1C values. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
STUDY DESIGN A systematic review and meta-analysis. INTRODUCTION Carpal tunnel syndrome (CTS) is one of the most common upper extremity conditions which mostly affect women. Management of patients suffering from both CTS and diabetes mellitus (DM) is challenging, and it was suggested that DM might affect the diagnosis as well as the outcome of surgical treatment. PURPOSE OF THE STUDY This meta-analysis was aimed to compare the response with CTS surgical treatment in diabetic and nondiabetic patients. METHODS Electronic databases were searched to identify eligible studies comparing the symptomatic, functional, and neurophysiological outcomes between diabetic and nondiabetic patients with CTS. Pooled MDs with 95% CIs were applied to assess the level of outcome improvements. RESULTS Ten articles with 2869 subjects were included. The sensory conduction velocities in the wrist-palm and wrist-middle finger segments showed a significantly better improvement in nondiabetic compared with diabetic patients (MD = -4.31, 95% CI = -5.89 to -2.74, P < .001 and MD = -2.74, 95% CI = -5.32 to -0.16, P = .037, respectively). However, no significant differences were found for the improvement of symptoms severity and functional status based on the Boston Carpal Tunnel Questionnaire and Quick Disabilities of the Arm, Shoulder, and Hand questionnaire as well as motor conduction velocities and distal motor latencies. CONCLUSION Metaresults revealed no significant difference in improvements of all various outcomes except sensory conduction velocities after CTS surgery between diabetic and nondiabetic patients. A better diabetic neuropathy care is recommended to achieve better sensory recovery after CTS surgery in diabetic patients.

Cold Sensitivity in Ulnar Neuropathy at the Elbow - Relation to Symptoms and Disability, Influence of Diabetes and Impact on Surgical Outcome. FRONTIERS IN CLINICAL DIABETES AND HEALTHCARE 2021; 2:719104. [PMID: 36994349 PMCID: PMC10012061 DOI: 10.3389/fcdhc.2021.719104] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2021] [Accepted: 07/27/2021] [Indexed: 11/13/2022]
Abstract
Cold sensitivity, an abnormal response to exposure to cold, is debilitating. It often affects people with nerve injuries and diabetes. Knowledge about the occurrence and prognostic impact of cold sensitivity in people with ulnar neuropathy at the elbow (UNE) is limited. We aimed to investigate the occurrence of cold sensitivity in UNE in relation to disability, the influence of diabetes and impact on surgical outcome. Data concerning 1270 persons operated on for UNE from 2010-2016 from the Swedish National Register for Hand Surgery (HAKIR) were matched with data from the Swedish National Diabetes Register (NDR). Disability and symptoms were assessed preoperatively, and at three and 12 months postoperatively using QuickDASH and a symptom-specific survey (HQ-8) containing one item regarding cold sensitivity. Differences regarding grade of cold sensitivity, occurrence of diabetes, QuickDASH scores and HQ-8 scores were studied. A linear regression analysis was performed to predict surgical outcome based on preoperative cold sensitivity. The mean age of the cases was 52 ± SD 14 years and 48% were women. Preoperatively, 427 answered the questionnaire. Severe cold sensitivity was present in 140/427 (33%) cases, moderate in 164/427 (38%) and mild in 123/427 (29%) cases. Cases with severe preoperative cold sensitivity reported higher QuickDASH scores at all times compared to cases with mild cold sensitivity. Relative change in QuickDASH scores over time did not differ between the groups. Cases with diabetes reported worse cold sensitivity preoperatively, but not postoperatively. All HQ-8 items improved with surgery, but cases with severe cold sensitivity reported worse persisting symptoms. Cold sensitivity is a major problem among those with UNE and an even greater preoperative problem among people with diabetes. It is associated with more symptoms and disability pre- and post-operatively. All cases, regardless of preoperative degree of cold sensitivity improve with surgery.

Abstract
AIM To compare vibrotactile sense, 5 years after carpal tunnel release in people with and without diabetes. METHODS Out of 35 people with diabetes and carpal tunnel syndrome, age- and gender-matched with 31 people without diabetes but with idiopathic carpal tunnel syndrome, 27 and 30 people, respectively, participated in this prolonged follow-up. Vibration perception threshold of the index and little finger (median and ulnar nerve, respectively), 5 years after surgery, was measured at seven different frequencies (8, 16, 32, 64, 125, 250 and 500 Hz). RESULTS Significant improvement of vibration perception threshold from 1 to 5 years after carpal tunnel release was found at 64 Hz for people with diabetes, while improvement for people without diabetes was demonstrated at several frequencies (64-250 Hz). However, both groups demonstrated a significant decrease in vibration perception threshold for the low frequencies (8-16 Hz). At 5 years, people with diabetes had significantly impaired vibration perception threshold at the index finger for high frequencies (125-500 Hz), and for nearly all frequencies (16 Hz, 64-500 Hz) at the little finger, compared to people without diabetes. CONCLUSION After carpal tunnel release, significant mid-term improvement of vibrotactile sense appears limited for people with diabetes, compared to a continuous improvement for people without diabetes. In addition, a decline in low-frequency vibrotactile sense occurs for the median as well as the ulnar nerve innervated fingers. Clinical Trial Registration NCT01201109.

Abstract
Cold sensitivity is common following nerve injuries in the upper extremity, but is less well studied in carpal tunnel syndrome (CTS). We investigated cold sensitivity in CTS and its effects on surgical outcome. A search of the Swedish National Registry for Hand Surgery (HAKIR) for open carpal tunnel releases (OCTR) from 2010-2016 identified 10,746 cases. Symptom severity questionnaires (HQ-8; HAKIR questionnaire 8, eight Likert-scale items scored 0-100, one item on cold sensitivity) and QuickDASH scores before and after surgery were collected. Patient mean age was 56 ± SD 16 years, and 7,150/10,746 (67%) were women. Patients with severe cold sensitivity (defined as cold intolerance symptom severity score > 70; n = 951), scored significantly higher on QuickDASH at all time points compared to those with mild cold sensitivity (cold intolerance symptom severity scores ≤ 30, n = 1,532); preoperatively 64 [50-75] vs. 40 [25-55], at three months 32 [14-52] vs. 18 [9-32] and at 12 months 25 [7-50] vs. 9 [2-23]; all p < 0.0001. Severe cold sensitivity predicted higher postoperative QuickDASH scores at three [12.9 points (95% CI 10.2-15.6; p < 0.0001)] and at 12 months [14.8 points (11.3-18.4; p < 0.0001)] compared to mild cold sensitivity, and adjustment for a concomitant condition in the hand/arm, including ulnar nerve compression, did not influence the results. Cold sensitivity improves after OCTR. A higher preoperative degree of cold sensitivity is associated with more preoperative and postoperative disability and symptoms than a lower degree of cold sensitivity, but with the same improvement in QuickDASH score.

Abstract
BACKGROUND Ulnar nerve entrapment at the elbow (UNE) is overrepresented in patients with diabetes, but the outcome of surgery is unknown. We aimed to evaluate patient-reported outcome in patients with and without diabetes, and to assess potential sex differences and compare surgical treatment methods. METHODS Data on patients operated for UNE (2010-2016, n = 1354) from the Swedish National Registry for Hand Surgery were linked to the Swedish National Diabetes Register. Symptoms were assessed preoperatively (n = 389), and 3 (n = 283), and at 12 months postoperatively (n = 267) by QuickDASH and HQ-8 (specific hand surgery questionnaire-8 questions). Only simple decompressions were included when comparing groups. RESULTS Men with diabetes reported higher postoperative QuickDASH scores than men without diabetes. Women scored their disability higher than men on all time-points in QuickDASH, but showed larger improvement between preoperative and 12 months postoperative values. Patients operated with transposition scored 10.8 points higher on QuickDASH than patients who had simple decompression at 12 months (95% confidence interval 1.98-19.6). CONCLUSIONS Women with diabetes benefit from simple decompression for UNE to the same extent as women without diabetes. Men with diabetes risk not to benefit from simple decompression as much as women do. Ulnar nerve transposition had a higher risk of residual symptoms compared to simple decompression.

Abstract
BACKGROUND Currently, we lack objective measures to quantify outcomes in carpal tunnel syndrome. Instead, surgeons rely on patient-reported outcomes measures (PROMs) to assess the effect of carpal tunnel release (CTR). We assessed the validity and reliability of wearable activity monitors to objectively characterize the functional and sleep impact of CTR. We hypothesized that actigraphy could detect changes in sleep and activity and would demonstrate short-term impairment due the operative procedure. METHODS This pilot, prospective, cohort study compared validated PROMS with actigraphy data obtained via wearable activity monitors (ActiGraph Link; ActiGraph Corp, Pensacola, Fla). Subjects completed baseline questionnaires and wore their device for 1 week preoperatively as a baseline. Subjects then underwent open CTR, wearing actigraphy devices for 4 weeks and completing questionnaires at 2 and 4 weeks postoperatively. Preintervention and postintervention data were compared using paired-sample t test. The Patient-Reported Outcomes Measurement Information System (PROMIS) questionnaire data were analyzed in accordance with published PROMIS scoring manuals and raw scores were converted to standardized T scores. RESULTS Twenty subjects (5 males, 15 females) with moderate or severe carpal tunnel syndrome were enrolled. The mean age was 57.7 years. The PROMIS 29 average cumulative T score was 42.9 with average change of -0.072 preoperatively versus postoperatively. Average sleep disturbance T score was 38.9 preoperatively and 41.4 postoperatively. There was no statistically significant difference in T score in any domain. The mean actigraphy activity data demonstrated near immediate return to baseline activity. Actigraphy sleep data demonstrate improvement in sleep fragmentation and decreased duration of awakenings. CONCLUSIONS Overall, patient-generated data detected differences in sleep and activity preoperatively versus postoperatively and demonstrated only a short period of activity disruption after CTR, which may be used when counseling patients. These data support actigraphy as a viable adjunct to traditional PROMS to evaluate the impact of surgical intervention and therefore may be useful in the study of other diseases affecting the upper extremity.

Abstract
BACKGROUND An increased rate of complications has been demonstrated with increasing hemoglobin A1c value for a variety of orthopedic procedures, including arthroplasty and spine surgery. The authors investigated the effects of elevated hemoglobin A1c value on postoperative complications at the time of carpal tunnel release. METHODS This retrospective, cohort study evaluated all diabetic patients with a preoperative hemoglobin A1c value within 90 days of primary, open carpal tunnel release at a single academic institution within the past 10 years. Binary hemoglobin A1c thresholds were tested for association with outcomes of superficial or deep infection, delayed wound healing, and persistent symptoms using chi-square analysis. Multivariable models with adjustment for baseline and operative factors were then constructed. Odds ratios and 95 percent confidence intervals were displayed. RESULTS Hemoglobin A1c value greater than or equal to 7.8 percent was most strongly associated with an increased risk of all-cause wound healing complications (p = 0.049) at an odds ratio of 4.2 (95 percent CI, 1.0 to 17.7) in adjusted analyses. Six patients (4 percent) experienced delayed wound healing and five patients (4 percent) developed a superficial infection. Six patients (4 percent) reported persistent carpal tunnel syndrome symptoms. CONCLUSIONS Diabetic patients undergoing open, primary carpal tunnel release with a hemoglobin A1c value of 7.8 percent or higher had a higher rate of postoperative wound complications compared to diabetic patients with improved preoperative glucose control. Diabetics with poor glycemic control should be counseled that their risk of postoperative complication is higher. Further work is needed to determine whether delaying surgery to optimize glucose control could result in a reduction of wound healing complications. CLINICAL QUESTION/LEVEL OF EVIDENCE Risk, II.

Abstract
OBJECTIVES To study patient-reported outcome after open carpal tunnel release (OCTR) for carpal tunnel syndrome (CTS) in patients with or without diabetes using national healthcare quality registries. DESIGN Retrospective cohort study. SETTING Data from the Swedish National Quality Registry for Hand Surgery (HAKIR; www.hakir.se) were linked to data from the Swedish National Diabetes Register (NDR; www.ndr.nu). PARTICIPANTS We identified 9049 patients (10 770 hands) operated for CTS during the inclusion period (2010-2016). PRIMARY OUTCOME MEASURES Patient-reported outcome measures were analysed before surgery and at 3 and 12 months postoperatively using the QuickDASH as well as the HAKIR questionnaire with eight questions on hand symptoms and disability. RESULTS Patients with diabetes (n=1508; 14%) scored higher in the QuickDASH both preoperatively and postoperatively than patients without diabetes, but the total score change between preoperative and postoperative QuickDASH was equal between patients with and without diabetes. The results did not differ between patients with type 1 or type 2 diabetes. Patients with diabetic retinopathy scored higher in QuickDASH at 3 months postoperatively than patients with diabetes without retinopathy. In the regression analysis, diabetes was associated with more residual symptoms at 3 and 12 months postoperatively. CONCLUSIONS Patients with diabetes experience more symptoms both before and after OCTR, but can expect the same relative improvement from surgery as patients without diabetes . Patients with retinopathy, as a proxy for neuropathy, may need longer time for symptoms to resolve after OCTR. Smoking, older age, higher HbA1c levels and receiving a diabetes diagnosis after surgery were associated with more residual symptoms following OCTR.

Abstract
Background: The purpose of this study was to determine the rates and types of complications and secondary surgeries after mini-open carpal tunnel release. Methods: A retrospective cohort study was performed for 1,328 patients who underwent mini-open carpal tunnel release from August 2008 to July 2013. Patients were excluded for acute trauma, the index procedure being revision surgery, neoplasm, age less than 18 years, incomplete records, and postoperative follow-up less than 1 month, which yielded 904 patients who underwent 1,144 surgeries. Results: Of 1,144 carpal tunnel releases performed, 14 (1.2%) were noted to have a complication at final follow-up, with no cases of major nerve or vessel injury. Fourteen patients (1.2%) underwent secondary surgery, including 11 cases for persistent or recurrent carpal tunnel syndrome and 3 cases for infection or hematoma. Chronic kidney disease was associated with an increased risk of complication. Diabetes mellitus, chronic kidney disease, and cervical radiculopathy were associated with an increased risk of secondary surgery. Conclusions: The short-term complication and secondary surgery rates of mini-open carpal tunnel release are low. Patients with diabetes mellitus, chronic kidney disease, and cervical radiculopathy should be counseled regarding risks of complication and secondary surgery.

Abstract
BACKGROUND The primary goal of the study was to evaluate the association of hemoglobin A1c (HbA1c) levels in diabetic patients with the incidence of surgical site infection (SSI) following open carpal tunnel release (CTR). Our secondary objective was to calculate an HbA1c level in diabetic patients that predicted SSI after open CTR. METHODS A national private-payer insurance database was queried for patients who underwent open CTR using Current Procedural Terminology (CPT) code 64721. Patients who underwent concomitant procedures were excluded. Diabetic patients who had their HbA1c level checked within 3 months of surgery were stratified into 6 mutually exclusive groups based on HbA1c levels in 1.0 mg/dL increments from <6.0 to >10 mg/dL. The incidence of SSI was determined for each group by either a diagnosis or procedure for SSI within 1 year using CPT and International Classification of Diseases, 9th Revision (ICD-9) codes. A receiver operating characteristic (ROC) analysis was performed to determine an HbA1c level above which the risk of postoperative SSI was significantly increased. RESULTS 7958 diabetic patients who underwent open CTR and had an HbA1c recorded within 3 months of surgery were assessed. The incidence of SSI within 1 year was associated with HbA1c levels. The inflection point of the ROC curve corresponded to an HbA1c level between 7 and 8 mg/dL. CONCLUSIONS Increased HbA1c levels are associated with increased SSI rates in diabetic patients undergoing open CTR. A perioperative HbA1c between 7 and 8 mg/dL could serve as a threshold for an increased risk of SSI following open CTR.

Abstract
BACKGROUND Over the last decade, surgical decompression procedures have been commonly used in the treatment of diabetic peripheral neuropathy (DPN). However, the effectiveness of them remains to be proved. METHODS A comprehensive literature search of databases including PubMed-Medline, Ovid-Embase, and Cochrane Library was performed to collect the related literatures. The Medical Subject Headings used were "diabetic neuropathy," "surgical decompression," and "outcomes." The methodological index for nonrandomized studies was adopted for assessing the studies included in this review. Analyses were performed with Review Manager (Version 5.3, The Nordic Cochrane Centre, the Cochrane Collaboration, Copenhagen, 2014). RESULTS A total of 12 literatures (including 8 prospective and 4 retrospective) encompassing 1825 patients with DPN were included in the final analysis. Only 1 literature was identified as a randomized-controlled trial. The remaining 11 literatures were observational studies; 7 of them were classified as upper-extremity nerve decompression group and 4 of them were classified as lower-extremity nerve decompression group. Meta-analysis shows that Boston questionnaire symptom severity and functional status of upper extremities, and distal motor latency and sensory conduction velocity of median nerve of DPN patients are significantly improved after carpal tunnel release. Besides, visual analog scale and 2-point discrimination are considered clinically and statistically significant in lower extremities after operation. CONCLUSIONS The findings from our review have shown the efficacy of surgical decompression procedures in relieving the neurologic symptoms and restoring the sensory deficits in DPN patients. As there are few high-quality randomized-controlled trials or well-designed prospective studies, more data are needed to elucidate the role of surgical procedures for DPN treatment in the future.

Raynaud's phenomenon in Northern Sweden: a population-based nested case-control study. Rheumatol Int 2018; 39:265-275. [PMID: 30128730 DOI: 10.1007/s00296-018-4133-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2018] [Accepted: 08/14/2018] [Indexed: 10/28/2022]
Abstract
The aim of this study was to determine the association between individual and external exposure factors, and the reporting of Raynaud's phenomenon, with or without concomitant cold sensitivity. In a population-based nested case-control study, cases with Raynaud's phenomenon (N = 578), and matched controls (N = 1156), were asked to respond to a questionnaire focusing on different risk factors. Univariate and multiple conditional logistic regression were performed. Analyses were stratified according to whether the cases reported cold sensitivity or not. In total, 1400 out of 1734 study subjects answered the questionnaire (response rate 80.7%). In the final multiple model, the factor with the strongest association to Raynaud's phenomenon, with and without cold sensitivity, was previous frostbite affecting the hands (OR 12.44; 95% CI 5.84-26.52 and OR 4.01; 95% CI 1.78-9.01, respectively). Upper extremity nerve injury was associated to reporting Raynaud's phenomenon and cold sensitivity (OR 2.23; 95% CI 1.29-3.85), but not Raynaud's phenomenon alone. Reporting any exposure to hand-arm vibration or cumulative cold exposure was significant in univariate analyses for cases with both Raynaud's phenomenon and cold sensitivity, but not in the multiple model. Raynaud's phenomenon is strongly associated to previous cold injury, with a larger effect size among those who also report cold sensitivity. The fact that only upper extremity nerve injury differed significantly between case groups in our multiple model offers additional support to the neural basis for cold sensitivity.

Abstract
UNLABELLED Diabetes mellitus (DM) is associated with the development of carpal tunnel syndrome, Dupuytren disease, trigger digits, and limited joint mobility. Despite descriptions of poorer response to nonsurgical treatment, previous studies have not shown increased complication rates in diabetic patients after hand surgery. Few studies, however, differentiate between insulin-dependent (IDDM) and non-insulin-dependent (NIDDM) diabetes mellitus. The purpose of this study was to evaluate the impact of insulin dependence on the postoperative risk profile of diabetic patients after hand surgery using a national database. MATERIALS AND METHODS The data were obtained through the National Surgical Quality Improvement Program (NSQIP) database. Patients undergoing surgery from the distal humerus to the hand, between 2005 and 2015, were identified using 297 distinct Current Procedural Terminology codes. Thirty-day postoperative complications were collected and categorized into medical complications, surgical site complications, and readmission. Surgical complications, medical complications, and readmissions were compared between patients with NIDDM or IDDM to those without DM using multivariable logistic regression, adjusting for baseline patient and operative characteristics. RESULTS The study cohort included 52,727 patients. Patients with IDDM had a 5.7% overall complication rate compared with 2.3% and 1.5% in NIDDM and nondiabetic patients, respectively. After controlling for differences in patient and surgical characteristics, patients with IDDM had a statistically significant increased rate of any complication, surgical site complications, superficial surgical site infections, and readmission. There was no significant difference in complication rates between patients with NIDDM and nondiabetic patients. CONCLUSIONS Our data demonstrate a greater risk of complications following hand and upper extremity surgery for patients with IDDM, specifically surgical site infections. The NIDDM patients did not have an increased rate of complications relative to nondiabetic patients. These findings are important for patient risk stratification and may guide further investigation to decrease complication rates in IDDM patients after upper extremity surgery. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.

Abstract
Purpose To identify factors associated with the reporting of cold sensitivity, by comparing cases to controls with regard to anthropometry, previous illnesses and injuries, as well as external exposures such as hand–arm vibration (HAV) and ambient cold. Methods Through a questionnaire responded to by the general population, ages 18–70, living in Northern Sweden (N = 12,627), cold sensitivity cases (N = 502) and matched controls (N = 1004) were identified, and asked to respond to a second questionnaire focusing on different aspects of cold sensitivity as well as individual and external exposure factors suggested to be related to the condition. Conditional logistic regression analyses were performed to determine statistical significance. Results In total, 997 out of 1506 study subjects answered the second questionnaire, yielding a response rate of 81.7%. In the multiple conditional logistic regression model, identified associated factors among cold sensitive cases were: frostbite affecting the hands (OR 10.3, 95% CI 5.5–19.3); rheumatic disease (OR 3.1, 95% CI 1.7–5.7); upper extremity nerve injury (OR 2.0, 95% CI 1.3–3.0); migraines (OR 2.4, 95% CI 1.3–4.3); and vascular disease (OR 1.9, 95% CI 1.2–2.9). A body mass index ≥ 25 was inversely related to reporting of cold sensitivity (0.4, 95% CI 0.3–0.6). Conclusions Cold sensitivity was associated with both individual and external exposure factors. Being overweight was associated with a lower occurrence of cold sensitivity; and among the acquired conditions, both cold injuries, rheumatic diseases, nerve injuries, migraines and vascular diseases were associated with the reporting of cold sensitivity.

Abstract
INTRODUCTION The long-term results of neurophysiological recovery after carpal tunnel release in patients with diabetes have not been studied. METHODS Thirty-five patients with diabetes and carpal tunnel syndrome (CTS) were matched with 31 patients without diabetes who had idiopathic CTS, and 27 and 30 patients, respectively, participated in this follow-up study. Nerve conduction results at 5 years were compared with previously published results at baseline and 1 year. RESULTS Significant neurophysiological improvement continued from 1 to 5 years after carpal tunnel release for patients with and without diabetes. However, wrist-palm sensory conduction velocity was still abnormal for 85% and 43% of patients with and without diabetes, respectively. Although diabetes had an impact on 4 of 10 measured neurophysiological parameters, the influence of peripheral neuropathy seemed insignificant. DISCUSSION After carpal tunnel release, significant long-term neurophysiological improvement is possible for patients with diabetes, and it is not influenced by the presence of peripheral neuropathy.

Abstract
BACKGROUND In making the decision to undergo carpal tunnel release (CTR), patients may consider probability of symptom resolution. Prior studies have examined potential preoperative variables that might influence the postoperative outcome. Few studies, however, contain the sample size, prospective design, and high participant completion rate to provide solid data from which to counsel patients. The purpose of this study was to prospectively evaluate factors that have been implicated or dismissed in past studies as sources of outcome variation following CTR surgery and provide patient-relatable facts that the surgeon might use in preoperative patient counseling. METHODS One thousand thirty-one consecutive patients undergoing open CTR were prospectively enrolled. Preoperative frequency of daytime numbness, nighttime awakening, and duration of symptoms were recorded in addition to physical exam, height, weight, gender, history of diabetes, history of thyroid disease, and severity of electrodiagnostic findings. After surgery, patients reported percent resolution of numbness at defined intervals. RESULTS Age and gender are the only independent factors that predict the degree of resolution of numbness 6 months following surgery. All other studied variables are not independent factors nor are any paired combinations of factors. Below the age of 50, the average reported resolution of daytime numbness by 6 months is 97.3% (men 91.8% and women 99.4%). After age 50, there is a linear 0.77% decline in average resolution of daytime numbness per year. CONCLUSIONS Age and gender but no other studied factors predict resolution of daytime numbness in a multivariate model of patients undergoing CTR.

Abstract
Purpose To determine susceptibility to decompression surgery in diabetic and nondiabetic peripheral neuropathy using a chronic compression neuropathy model. Materials and methods Twenty-four streptozotocin-induced diabetic rats were randomly divided into three groups: group I, chronic compression of the left sciatic nerve for 4 weeks with decompression; group II, similar without decompression; and group III, sham exposing the sciatic nerve only. The other 24 nondiabetic rats were assigned to groups IV–VI, which received compression–decompression, compression, and the sham operation, respectively. Mixed-nerve-elicited somatosensory evoked potentials (M-SSEPs) and compound muscle action potentials (CMAPs) were measured to verify the compression neuropathy in the posttreatment follow-up. Behavioral observations in thermal hyperalgesia tests were quantified before electrophysiologic examinations. Treated and contralateral nerves were harvested for histomorphologic analysis. Results Chronic compression of sciatic nerve induced significant reduction of amplitude and increment of latency of M-SSEP and CMAP in both diabetic and nondiabetic rats. Diabetic group changes were more susceptible. Decompression surgery significantly improved both sensory and motor conduction, thermal hyperalgesia, and the mean myelin diameter of the rat sciatic nerve in both diabetic and nondiabetic groups. Near full recovery of motor and sensory function occurred in the nondiabetic rats, but not in the diabetic rats 8 weeks postdecompression. Conclusion Behavioral, electrophysiologic, and histomorphologic findings indicate that decompression surgery is effective in both diabetic and nondiabetic peripheral neuropathy.

Abstract
An increasing number of orthopaedic surgeries are performed at ambulatory surgical centers (ASCs), as is exemplified by the 272% population-adjusted increase in outpatient rotator cuff repairs from 1996 to 2006. Outpatient surgery is convenient for patients and cost effective for the healthcare system. The rate of complications and adverse events following orthopaedic surgeries at ASCs ranges from 0.05% to 20%. The most common complications are pain and nausea, followed by infection, impaired healing, and bleeding; these are affected by surgical and patient risk factors. The most important surgeon-controlled factors are surgical time, type of anesthesia, and site of surgery, whereas the key patient comorbidities are advanced age, female sex, diabetes mellitus, smoking status, and high body mass index. As the use of ASCs continues to rise, an understanding of risk factors and outcomes becomes increasingly important to guide indications for and management of orthopaedic surgery in the outpatient setting.

Abstract
BACKGROUND Night pain has important diagnostic and prognostic values in patients with carpal tunnel syndrome (CTS). We aimed to determine whether night pain is associated with certain patient characteristics in female patients undergoing carpal tunnel release. METHODS We recruited 75 women with the mean age of 54 years who were scheduled for carpal tunnel release. Diagnosis of CTS was made based on both the clinical symptoms and the results of electrophysiologic studies. Patient characteristics investigated as factors potentially associated with night pain were: age, body mass index (BMI), symptom duration, comorbidities such as diabetes mellitus (DM) and thyroid disease, electrophysiologic severity of CTS, and sleep position. We conducted a logistic regression analysis to examine the relationships between the presence of night pain and the different patients' demographic and clinical variables. RESULTS Absence of night pain was associated with increased age (odds ratio (OR), 0.918, 95% confidence interval (CI), 0.851 to 0.99) and presence of DM (OR, 0.196; 95% CI, 0.046 to 0.835). The other variables assessed were not found to be associated with presence or absence of night pain. CONCLUSIONS This study found that in women undergoing carpal tunnel release, older patients or those having DM are slightly less likely to have night pain. As night pain is an important prognostic factor for CTS, further studies are warranted to determine whether the absence of night pain could affect outcome assessment of CTS in the elderly or patients with DM.

Abstract
Diabetes mellitus (DM) can accompany many musculoskeletal (MSK) diseases. It is difficult to distinguish the DM-related MSK diseases based on clinical symptoms alone. Sonography is frequently used as a first imaging study for these MSK symptoms and is helpful to differentiate the various DM-related MSK diseases. This pictorial essay focuses on sonographic findings of various MSK diseases that can occur in diabetic patients.

Abstract
PURPOSE The American College of Surgeons Surgical Quality Improvement Program database collects detailed and validated data on demographics, comorbidities, and 30-day postoperative outcomes of patients undergoing operations in most subspecialties. This dataset has been previously used to quantify complications and identify risk factors in other surgical subspecialties. We sought to determine the incidence of postoperative complications following hand surgery and to identify factors associated with increased risk of complications in order to focus preventive strategies. METHODS National Surgical Quality Improvement Program data from 2006 to 2011 were queried using 302 hand-specific Current Procedural Technology codes. Descriptive statistics were calculated for the population, and potential risk factors and patient characteristics were analyzed for their association with complications in the 30-day postoperative period using both univariate and multivariate analyses. RESULTS There were 208 hand-specific Current Procedural Technology codes represented in the data, and of these, 84 were associated with at least 1 complication. The overall incidence of complications within 30 days of hand surgery was 2.5% (95% confidence interval, 2.2%-2.8%). In univariate analysis, older age, diabetes, chronic obstructive pulmonary disease, congestive heart failure, atherosclerosis, steroids, bleeding disorder, increasing American Society of Anesthesiologists class, increasing wound class, emergency procedure, longer operative time, and preoperative transfusion were associated with significantly higher risk of complications, and local anesthesia and outpatient surgery were associated with lower risk. In the multivariate model, male sex, increasing American Society of Anesthesiologists class, wound class 4, and preoperative transfusion were associated with significantly higher risk, and outpatient surgery was associated with significantly lower risk. The most common complication was surgical-site infection (1.2%). CONCLUSIONS The incidence of complications was low, with overall health status being more important than specific comorbidities in predicting complication risk. This information may be valuable in counseling patients before surgery and in identifying patients at higher risk for complications following hand surgery.

Abstract
PURPOSE To compare outcomes of carpal tunnel release in patients with or without metabolic syndrome. METHODS In a prospective consecutive series, 35 patients with metabolic syndrome and surgically treated carpal tunnel syndrome (CTS) were age- and sex- matched with 37 control patients without metabolic syndrome. Grip, pinch strength, perception of touch with Semmes-Weinstein monofilament, and Boston Carpal Tunnel Questionnaires (BCTQ) were assessed preoperatively and at 3, 6, and 12 months postoperatively. RESULTS Patients with metabolic syndrome had more severe electrophysiologic grade of CTS than those without metabolic syndrome, but the 2 groups had similar preoperative grip/pinch strength and BCTQ scores. The BCTQ symptom score for the metabolic syndrome group was significantly greater than that of the control group at 3 months, and the BCTQ function score of the metabolic syndrome group was significantly greater than that of the control group at 3 and 6 months' follow-up. However, there was no significant difference in BCTQ symptom or functional scores between groups at 12 months' follow-up. There was no significant difference in grip strength between groups through 12 months' follow-up whereas the pinch strength of the control group was significantly greater than that of the metabolic syndrome group at 12 months' follow-up. Semmes-Weinstein monofilament test results were significantly greater in the control group than in the metabolic syndrome group at 3 and 6 months' follow-up but were similar at 12 months. CONCLUSIONS Patients with CTS and metabolic syndrome have delayed functional recovery after carpal tunnel release, but noteworthy improvements in symptom severity and hand function are similar to those in patients without metabolic syndrome 1 year after surgery.

AIMS/HYPOTHESIS We addressed the question of whether the autophagy pathway occurs in human peripheral nerves and whether this pathway is associated with peripheral neuropathy in diabetes mellitus. METHODS By using electron microscopy, we evaluated the presence of autophagy-related structures and neuropathy in the posterior interosseous nerve of patients who had undergone carpal tunnel release and had type 1 or type 2 diabetes mellitus, and in patients with no diabetes (controls). RESULTS Autophagy-related ultrastructures were observed in the samples taken from all patients of the three groups. The number of autophagy-associated structures was significantly higher (p < 0.05) in the nerves of patients with type 1 than type 2 diabetes. Qualitative and quantitative evaluations of fascicle area, diameter of myelinated and unmyelinated nerve fibres, the density of myelinated and unmyelinated fibres and the g-ratio of myelinated fibres were performed. We found degeneration and regeneration of a few myelinated axons in controls, and a well-developed neuropathy with the loss of large myelinated axons and the presence of many small ones in patients with diabetes. The pathology in type 1 diabetes was more extensive than in type 2 diabetes. CONCLUSIONS/INTERPRETATION The results of this study show that the human peripheral nerves have access to the autophagy machinery, and this pathway may be regulated differently in type 1 and type 2 diabetes; insulin, presence of extensive neuropathy, and/or other factors such as duration of diabetes and HbA1c level may underlie this differential regulation.

Abstract
BACKGROUND Diabetic neuropathy is a common complication of diabetes mellitus. The length-dependent symmetrical sensorimotor type of neuropathy is the most prevalent form of diabetic neuropathy but other forms of diabetic neuropathy also need to be kept in mind. Their differential diagnosis is often more challenging but implicates specific forms of treatment other than improvement of metabolic control. AIM OF THE STUDY This article gives an overview of the less frequent forms of diabetic neuropathy and discusses their impact, diagnostic and therapeutic implications. RESULTS Autonomic diabetic neuropathy, diabetic small fiber neuropathy and less frequent forms of diabetic neuropathy, such as diabetic radiculoplexopathy, diabetic neuropathy of cranial nerves, therapy-induced neuropathy and alternative causes of peripheral neuropathy in patients with diabetes are described. DISCUSSION Diagnosis of less frequent subtypes of diabetic neuropathy and differentiation towards alternative causes of peripheral neuropathy are often difficult in daily medical routine. Diagnostic clues are helpful in identifying rarer forms of diabetic neuropathy, thus enabling more specific treatment.

Abstract
BACKGROUND Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy encountered in diabetes. The short-term improvement after carpal tunnel release has previously been demonstrated not to differ between patients with and without diabetes, despite a marked impairment in health-related quality of life (HRQL) among the former. In this study, we compare HRQL 5 years after carpal tunnel release between these two groups of patients. METHODS In a prospective series, 35 patients with diabetes and CTS were matched with 31 control patients with idiopathic CTS but no diabetes. At the 5-year follow-up patients completed the Medical Outcomes Short-Form 36 (SF-36) and Antonovsky's sense of coherence (SOC) questionnaire. Differences in changes over time were compared between patients with and without diabetes using mixed model analysis. RESULTS Although patients with diabetes reported a significant decrease in physical functioning (p =0.004) as compared to patients without diabetes, postoperative improvement was maintained in the physical domains, role physical and bodily pain. A more pronounced decline in the mental health domain, social function (p =0.03), was demonstrated among patients with diabetes. There was no evidence of any difference in SOC between the patient groups. CONCLUSION Patients with diabetes retained their improvement in physical domains sensitive to changes after carpal tunnel release in the long-term, despite a decline in other domains of both physical and mental HRQL. This differed from patients without diabetes. Differences in SOC could not explain the sharper decline in these domains among patients with diabetes.

Abstract
Diabetic neuropathies (DNs) differ in clinical course, distribution, fiber involvement (type and size), and pathophysiology, the most typical type being a length-dependent distal symmetric polyneuropathy (DSP) with differing degrees of autonomic involvement. The pathogenesis of diabetic DSP is multifactorial, including increased mitochondrial production of free radicals due to hyperglycemia-induced oxidative stress. Mechanisms that impact neuronal activity, mitochondrial function, membrane permeability, and endothelial function include formation of advanced glycosylation end products, activation of polyol aldose reductase signaling, activation of poly(ADP ribose) polymerase, and altered function of the Na(+)/K(+)-ATPase pump. Hyperglycemia-induced endoplasmic reticulum stress triggers several neuronal apoptotic processes. Additional mechanisms include impaired nerve perfusion, dyslipidemia, altered redox status, low-grade inflammation, and perturbation of calcium balance. Successful therapies require an integrated approach targeting these mechanisms. Intensive glycemic control is essential but is insufficient to prevent onset or progression of DSP, and disease-modifying treatments for DSP have been disappointing. Atypical forms of DN include subacute-onset sensory (symmetric) or motor (asymmetric) predominant conditions that are frequently painful but generally self-limited. DNs are a major cause of disability, associated with reduced quality of life and increased mortality.

Abstract
LEARNING OBJECTIVES After studying this article, the participant should be able to: (1) Describe and apply the best current high-level evidence in carpal tunnel syndrome. (2) Design a treatment plan to offer tourniquet-free, sedation-free local anesthesia for patients who wish it or who are at high risk with sedation. (3) Describe the evidence and outcomes as they relate to splinting carpal tunnel patients after surgery. SUMMARY This is the third Maintenance of Certification article on carpal tunnel syndrome. Hentz and Lalonde summarized the best literature in 2008 in the first article. The second article, by Shores and Lee, presented the best evidence regarding assessment, surgical treatment, and outcomes from the literature published between 1999 and 2009. In this article, the author has concentrated on topics not covered in depth in the first two articles and provides an update of the highest level evidence on important topics from 2009 to 2013. Although there is some Level IV and V evidence cited in this article, most is Level I, II, and III.

Abstract
PURPOSE To compare clinical outcomes 5 years after carpal tunnel release among patients with and without diabetes. METHODS In a prospective consecutive series, 35 patients with diabetes (median age, 54 y; 15 type 1 and 20 type 2 diabetes) with carpal tunnel syndrome were age- and sex-matched with 31 control patients without diabetes (median age, 51 y) with idiopathic carpal tunnel syndrome. Exclusion criteria were other nerve entrapment, cervical radiculopathy, inflammatory joint disease, thyroid disorder, previous wrist fracture, and long-term exposure to vibrating tools. Participants were examined independently at baseline, 1 year, and 5 years after surgery for sensory function (Semmes-Weinstein), motor function (abductor pollicis brevis muscle strength and grip strength), cold intolerance, and completion of the Boston Carpal Tunnel Questionnaire symptom severity and functional status score. RESULTS Five years after surgery, the overall attendance rate for clinical examinations and completion of the Boston Carpal Tunnel Questionnaire were 86% and 95%, respectively. Between 1 and 5 years after surgery, there was a tendency toward a decrease in sensory function but an increase in motor function, with no statistically significant difference between groups. Cold intolerance demonstrated long-term significant improvement for patients with diabetes. The improvement in symptom severity and functional status score, as well as the large effect size, were maintained at 5 years in both patient groups. CONCLUSIONS Long-term improvement in patients with diabetes remained after carpal tunnel release to the same extent as for patients without diabetes. Furthermore, improvement in cold intolerance in patients with diabetes suggests the potential for the long-term regeneration of small nerve fibers. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic I.

Abstract
BACKGROUND Cold sensitivity is a common complaint following hand injuries. Our aim was to investigate long-term self-reported cold sensitivity, and its predictors and the importance of sense of coherence (SOC), 8 years after a hand injury as well as in patients treated for Hand Arm Vibration Syndrome (HAVS) during the same time period. METHODS Responses to the Cold Intolerance Symptom Severity (CISS) questionnaire and the Sense of Coherence (SOC) questionnaire were investigated in hand injured patients (n = 64) and in patients with HAVS (n = 26). The Mann-Whitney U-Test was used to identify significant differences between subgroups. When analysing predictors for cold sensitivity severity, the Spearman rank correlation (rS coefficient) were used for quantitative predictive variables, Mann-Whitney U-Test for dichotomous variables and Kruskal-Wallis Test for multiple categorical data. The Wilcoxon's signed rank test was used to investigate longitudinal changes in outcome. RESULTS There was a significant change in total CISS score for patients with traumatic hand injury, indicating fewer problems with cold sensitivity over time. Symptoms, such as stiffness, weakness and skin colour change on cold exposure, caused fewer problems, but perceived pain/aching and numbness remained unchanged as well as time needed for relief of symptoms on return to a warm environment. The negative impact of cold sensitivity on daily activities and at work was reduced, but problems when engaged in hobbies or when being exposed to cold wintry weather remained unchanged. None of the investigated predictors related to the hand injury were significantly associated with a change in cold sensitivity at the 8-year follow up. In contrast, no significant change in cold sensitivity was noted in the patients with HAVS for any of the situations included in the CISS questionnaire. A lower sense of coherence score correlated significantly with worse cold sensitivity (CISS score) in both patient groups. CONCLUSIONS The negative impact of cold sensitivity on daily life was reduced for patients with traumatic hand injury, but did not change over time in patients with HAVS. A low SOC is associated with worse cold sensitivity in such groups of patients. Information about relieving strategies should be provided for patients with cold sensitivity.

Abstract
Prolonged exposure to hand-held vibrating tools may cause a hand-arm vibration syndrome (HAVS), sometimes with individual susceptibility. The neurological symptoms seen in HAVS are similar to symptoms seen in patients with carpal tunnel syndrome (CTS) and there is a strong relationship between CTS and the use of vibrating tools. Vibration exposure to the hand is known to induce demyelination of nerve fibres and to reduce the density of myelinated nerve fibres in the nerve trunks. In view of current knowledge regarding the clinical effects of low nerve-fibre density in patients with neuropathies of varying aetiologies, such as diabetes, and that such a low density may lead to nerve entrapment symptoms, a reduction in myelinated nerve fibres may be a key factor behind the symptoms also seen in patients with HAVS and CTS. Furthermore, a reduced nerve-fibre density may result in a changed afferent signal pattern, resulting in turn in alterations in the brain, further prompting the symptoms seen in patients with HAVS and CTS. We conclude that a low nerve-fibre density lead to symptoms associated with nerve entrapment, such as CTS, in some patients with HAVS.

Abstract
BACKGROUND The aim of this prospective study was to compare the results of surgical decompression of carpal tunnel syndrome (CTS) in patients with diabetes mellitus with those with idiopathic CTS. METHODS The results of surgical decompression of CTS in 27 patients with diabetes mellitus were compared with 42 patients with idiopathic CTS. All patients underwent surgical release of transverse carpal ligament by the mini-incision of palm technique. Patient self-administered Boston Questionnaire (BQ) for the assessment of severity of CTS symptoms and hand functional status was evaluated before and 6 months and 10 years after surgery. RESULTS After surgical release, all the patients of both groups reported an absence of pain, disappearance or reduction of paresthesia, and improvement in hand function. Six months after surgery, there was a significant improvement of symptomatic and functional BQ scores compared with preoperative state in both groups. Ten years after surgery, there was statistical difference in preoperative and postoperative 10th year functional BQ score between DM (-) and DM (+) (p < 0.01). DM status affected statistically functional BQ score between preoperative and postoperative 10th year. CONCLUSION Diabetes mellitus was a risk factor for poor outcome of surgical decompression of CTS. Patients with diabetes had worse surgical outcome compared with patients with idiopathic CTS in long-term follow-up.

Abstract
BACKGROUND Establishing the minimal clinically important difference for patient-reported outcomes questionnaires is essential in outcomes research to evaluate the patient's perspective of treatment effectiveness. The authors aim to determine the minimal clinically important difference after carpal tunnel release in diabetic and nondiabetic patients using the Boston Carpal Tunnel Questionnaire. METHODS The authors prospectively evaluated 114 patients (87 nondiabetic and 27 diabetic patients) undergoing carpal tunnel release. In addition to standard history and physical examination, the authors obtained preoperative electrodiagnostic studies to confirm carpal tunnel syndrome. The Boston Carpal Tunnel Questionnaire was administered before and after surgery at 3 and 6 months. Patients were asked about their level of satisfaction at the final follow-up visit. The authors applied the receiver operating characteristic curve approach to determine the minimal clinically important difference of symptom and function severity scales of the questionnaire. The authors used patient satisfaction as the reference standard to compare against the standardized change in scores after surgery for the two groups. RESULTS For both diabetic and nondiabetic patients, symptom and function severity scales showed large effect sizes of greater than 0.8 at 3 and 6 months after surgery. At 6 months after surgery, to be satisfied, diabetic patients required a minimal clinically important difference of 1.55 and 2.05 for symptom and function scales, respectively, whereas nondiabetic patients required 1.45 and 1.6, respectively. CONCLUSIONS Diabetic patients needed a greater improvement in Boston Carpal Tunnel Questionnaire score to be satisfied on functional and symptom severity scales than nondiabetic patients. Overall, diabetic patients had less improvement in Boston Carpal Tunnel Questionnaire final scores compared with nondiabetics. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, II.

Abstract
The coexistence of diabetes might complicate the diagnosis and operative outcomes of carpal tunnel syndrome. We retrospectively compared the results of carpal tunnel release in diabetic and non-diabetic patients. The group included 386 patients, 322 female (83%) and 64 male (17%) with a mean age of 57 years. A total of 41 patients (11%) were diabetic, whereas 345 (89%) did not have diabetes. Patients were followed-up at six months, by assessments that included Levine scores, filament tests, grip and pinch strength. No significant differences in any of the measured variables were found at the six-month assessment. The results of the study show that carpal tunnel release in diabetic and non-diabetic patients are similarly beneficial.

Abstract
PURPOSE OF REVIEW Diabetes is the most common cause of peripheral neuropathy in the world. More than half of patients with diabetes have neuropathy, and half of patients with neuropathy have diabetes. Diabetic neuropathy is a major cause of disability and health care expense. This article reviews the various forms of diabetic neuropathy with a focus on diagnosis and treatment. RECENT FINDINGS Diabetes causes a wide variety of peripheral nerve problems. These can be divided into chronic neuropathies, of which distal symmetric polyneuropathy is the most common, and acute neuropathies, such as diabetic amyotrophy. There is growing evidence suggesting that prediabetic levels of hyperglycemia and other consequences of obesity and dyslipidemia contribute to neuropathy risk. Evolving literature suggests that many of the acute diabetic neuropathies are related to inflammatory mechanisms. An important exception is treatment-related neuropathy, previously known as "insulin neuritis". SUMMARY While disease-altering therapy continues to prove elusive, our understanding of basic disease mechanisms is improving, and new diagnostic and research tools will hopefully lead to novel therapies for distal symmetric diabetic polyneuropathy.

Abstract
Diabetes mellitus is recognised as a risk factor for carpal tunnel syndrome. The response to treatment is unclear, and may be poorer than in non-diabetic patients. Previous randomised studies of interventions for carpal tunnel syndrome have specifically excluded diabetic patients. The aim of this study was to investigate the epidemiology of carpal tunnel syndrome in diabetic patients, and compare the outcome of carpal tunnel decompression with non-diabetic patients. The primary endpoint was improvement in the QuickDASH score. The prevalence of diabetes mellitus was 11.3% (176 of 1564). Diabetic patients were more likely to have severe neurophysiological findings at presentation. Patients with diabetes had poorer QuickDASH scores at one year post-operatively (p = 0.028), although the mean difference was lower than the minimal clinically important difference for this score. After controlling for underlying differences in age and gender, there was no difference between groups in the magnitude of improvement after decompression (p = 0.481). Patients with diabetes mellitus can therefore be expected to enjoy a similar improvement in function.
