Can we predict the compensatory hyperhidrosis following a thoracic sympathectomy?

Background

Primary hyperhidrosis is a functionally and socially disabling condition resulting in social embarrassment and low quality of life. Thoracic sympathectomy is a definitive choice of treatment with favorable results. However, patients may face another embarrassing condition following surgery as compensatory hyperhidrosis which has no definitive treatment. The predictors of compensatory hyperhidrosis are controversial and remain unclear.

Patients and methods

A total of 74 patients underwent a videothoracoscopic sympathectomy for primary hyperhidrosis. We statistically analyzed our patients with correlations and uni-multivariate logistic regression models to outline the possible predictors of compensatory hyperhidrosis.

Results

A total of 45 (60.8%) patients had compensatory hyperhidrosis. The correlations showed that patients, with age greater than 21 years (P = 0.018), with body mass index (BMI) greater than 22 kg / m² (P = 0.045), with isolated facial hyperhidrosis (P = 0.044), and with smoking status (P = 0.015), had significantly greater rates of compensatory hyperhidrosis. Similarly, the significant univariate predictors of compensatory hyperhidrosis were age > 21 (P = 0.020), BMI > 22 kg / m² (P = 0.048), and the presence of smoking status (P = 0.015). Multivariate analysis revealed only smoking as a predictor within the threshold of significance (P = 0.078).

Conclusion

The clinical predictors of compensatory hyperhidrosis following a thoracic sympathectomy appear as older age, greater body mass index, and smoking.

ENHO gene expression and serum adropin level in rheumatoid arthritis and systemic lupus erythematosus

BACKGROUND

Adropin, a secreted protein, is encoded by the energy homeostasis-associated gene (ENHO). It is expressed by a variety of tissues and cells. It has been implicated in several physiological and pathological processes, such as angiogenesis and apoptosis.

OBJECTIVES

The aim of the present study was to investigate the ENHO gene expression and serum adropin levels in patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE).

MATERIAL AND METHODS

The study included 36 patients with RA, 22 patients with SLE and 20 healthy controls (HC). Patients with a disease activity score-28-erythrocyte sedimentation rate (DAS28-ESR) >2.6 in the RA group and an SLE disease activity index (SLEDAI) >6 in the SLE group were accepted as active. Serum adropin levels were analyzed by the enzyme-linked immunosorbent assay (ELISA) method. The ENHO gene and glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene expressions in peripheral blood mononuclear cells were analyzed by real-time polymerase chain reaction (PCR).

RESULTS

The ENHO gene mRNA expression was significantly higher in the RA group than in the HC group (p = 0.024), although it was similar between the SLE and HC groups (p = 0.920). On the other hand, there were no significant differences among the study groups in terms of serum adropin levels (p > 0.05 for all). Moreover, there was no significant difference in terms of the ENHO expression and serum adropin levels between active and inactive RA and SLE patients.

CONCLUSIONS

Although the ENHO gene expression is increased, serum adropin level is not altered in RA. Similarly, adropin seems not to be associated with SLE. However, the potential link between adropin and inflammatory diseases need to be tested by further studies.

Ultrasonographic evaluation of the ankle after unilateral traumatic lower limb amputations

BACKGROUND

Unilateral lower limb amputation can alter the tissue morphology leading to increase future risk of degenerative secondary disorders.

METHODS

Thirty-four consecutive male patients with unilateral lower limb amputations of different levels and 34 well matched male controls were included. To explore whether the ankles of traumatic lower limb amputees were undergoing morphological changes, three different tissue types i.e. talar cartilage, plantar fascia and Achilles tendon thicknesses in the intact limb of the lower limb amputee and healthy controls were measured by using ultrasound.

RESULTS

Plantar fascia was found to be thicker (p=0.013) and talar cartilage was thinner (p<0.001) on the intact sides of the patients than those of the controls. Achilles tendon thickness was found to be similar. In patients group, plantar fascia thickness was positively correlated with age (r=0.601, p<0.001), BMI (r=0.454, p=0.007) and durations of amputation (r=0.443, p=0.009) and prosthetic use (r=0.429, p=0.011). Achilles tendon thickness was positively correlated with durations of amputation (r=0.338, p=0.05) and prosthetic use (r=0.468, p=0.005). In controls group, talar cartilage thickness was negatively correlated with age (r=-0.640, p<0.001) and BMI (r=-0.401, p=0.019).

CONCLUSIONS

The talar cartilage seemed to be thinner and the plantar fascia to be thicker on the intact sides of the unilateral limb amputees.

Influence of omega-3 fatty acid on orthodontic tooth movement in rats: A biochemical, histological, immunohistochemical and gene expression study

OBJECTIVE

The aim of this study was to investigate the effects of omega-3 fatty acids on orthodontic tooth movement.

SETTING AND SAMPLE POPULATION

For this study, 56 12-week-old adult male Wistar albino rats from the Animal Laboratory at Adnan Menderes University, Faculty of Medicine, were used.

MATERIAL AND METHODS

Rats were randomly divided into seven groups (n = 8 each): control group (without any treatment), tooth movement groups (three groups of animals with only tooth movement) and omega groups (three groups of animals with tooth movement and omega-3 administration). Omega-3 fatty acids were administered to the rats systemically during the tooth movement period. On the 3rd, 7th and 14th days after the orthodontic tooth movement, the rats were sacrificed and biochemical, histological, immunohistochemical andgene expression examinations were performed.

RESULTS

On the 14th experimental day, the amount of tooth movement in the omega groups was significantly lower than the tooth movement groups (P = 0.012). Biochemical experimentsshowed that the omega groups had significantly lower total oxidant levels and higher total antioxidant levels compared to the tooth movement group on the 14th experimental day (P = 0.001). The levels of RANKL, IL-6 and IL-1β in the omega groups were significantly lower than the tooth movement groups on all experimental days (P < 0.05).

CONCLUSION

Systemic administration of omega-3 fatty acids showed antioxidant and antiinflammatory effects and decelerate the orthodontic tooth movement.

The relationship between gestational diabetes mellitus and selenoprotein-P plasma 1 (SEPP1) gene polymorphisms

Our aim is to demonstrate any correlation between gestational diabetes mellitus (GDM) and polymorphism of the selenoprotein P (SEPP1) gene encoding the SEPP1 protein, having a role in the insulin resistance in GDM. Forty pregnant women with GDM and 40 healthy pregnant women were included in the study. In both groups, single nucleotide polymorphisms (SNPs), specifically, rs4987017, rs13154178, rs146125471, rs28919926, and rs16872762 were studied. There was no difference between the groups in terms of polymorphism rs146125471, rs28919926, or rs16872762 (p > .05). There was a significant difference in SNP rs13154178 polymorphism between the two groups (p < .01). When rs13154178 gene polymorphism was compared with AA homozygous individuals, fasting blood glucose levels were significantly higher in carriers of either polymorphism than in those with no polymorphism (p < .001). We suggest rs13154178 gene polymorphism may lead to GDM in the Turkish society.

Comment on Ultrasound Guidance for Botulinum Neurotoxin Chemodenervation Procedures. Toxins 2017, 10, 18-Quintessential Use of Ultrasound Guidance for Botulinum Toxin Injections-Muscle Innervation Zone Targeting Revisited

Recently, the importance of targeting structures during botulinum neurotoxin applications has been discussed in a variety of disorders, including spasticity and dystonia. In this respect, the advantages of ultrasound imaging to traditional techniques have been emphasized. We would like underscore the importance of ultrasound guidance, with targeting innervation zone(s) of the over-active muscles to achieve effective clinical outcomes. Additionally, we also clarify the difference between the terms—innervation zone (motor end plate) and motor point—which have been used by the authors as if they were the same. Further, we disagree with the authors about the intramuscular botulinum neurotoxin application techniques i.e., in-plane vs. out-of-plane whereby the former is, for sure, superior.

Ultrasonographic measurements of the metacarpophalangeal and talar cartilage thicknesses: A reliability study in healthy subjects

BACKGROUND

Assessment of the joint cartilage using ultrasound imaging is important.

OBJECTIVE

Our aim was to investigate the reliabilities of ultrasonographic measurements for talus dome (TCT) and metacarpal cartilage thicknesses (MCT).

METHODS

Twenty healthy volunteers were recruited in the study. Every day, five physiatrists measured eight joint cartilage thicknesses. They repeated all the measurements in five consecutive days.

RESULTS

Intra-observer intraclass correlation coefficient (ICC) values were "excellent" for all MCTs, except for the 3rd left MCT on the 1st day, 4th left MCT on the 1st day and 4th right MCT on the 3rd day which were "good". They were "excellent" for the TCT measurements, except for the left side on the 3rd day and the right side on the 4th day which were "good". Inter-observer ICC values pertaining to the 2nd MCT measurements were "excellent" for all sonographers. Third and 4th MCT measurements (at least one side) were "excellent" for four and three sonographers, respectively. On the other hand, while TCT measurements were "excellent" for 4 sonographers.

CONCLUSIONS

Our results have shown that sonographic measurements of MCT and TCT have good to excellent reliabilities in healthy adults. These findings support the use of ultrasound for cartilage assessment in various diseases.

Evaluation of Genetic Polymorphisms for Determining Steroid Response in Nephrotic Children

GOALS

Although all children with nephrotic syndrome (NS) have similar biochemical abnormalities and clinical manifestations, they seem to have variable grades of steroid responsiveness and patterns of disease relapse. Therefore, this study aimed to examine whether steroid metabolism-related genetic polymorphisms, which are responsible for drug elimination, play a role for steroid response in children with NS.

METHODS

The study population consisted of 53 children with idiopathic NS [45 steroid sensitive (SS) and 8 steroid resistant (SR) nephrotic patients] and 22 healthy children as the control group. The genetic polymorphisms of the multi-drug resistance-1 (MDR-1) and human cytochrome P450 3A (CYP3A4 and CYP3A5) genes were analyzed and compared between SS, SR and control groups. In addition, mutations in the podocin and nephrin genes were also investigated.

RESULTS

There was no statistically significant difference between NS and control groups in terms of age and gender (P>0.05). Although the NS was more prevalent in boys (39/53, 73.6%), females were more dominant in the SR group (5/8, 62.5%). Serum urea and creatinine values were significantly higher in the SR group than in the SS group. Mutations in the podocin and nephrin genes were not different between the groups (P>0.05). In addition, no difference was found between the groups in regard to the polymorphisms of the MDR-1, CYP3A4 and CYP3A5 genes (P>0.05).

CONCLUSION

These results showed that the polymorphisms of the MDR-1, CYP3A4 and CYP3A5 genes were not associated with steroid response.

Evaluation of Mediterranean diet adherence in patients with a history of coronary revascularization

INTRODUCTION

Lifestyle modification is an important component of the secondary prevention strategies; and a healthy diet is one of the cornerstones in management of the coronary heart disease. We aimed to investigate the dietary habits of the patients with history of coronary revascularization, characteristics of the ones with good adherence by using alternate MedDiet questionnaire.

METHODS

We included outpatients who had a history of coronary revascularization at least 6 months prior to enrollment. Each participant filled out a questionnaire to collect the data of demographics and clinical characteristics. Alternate MedDiet score was calculated to evaluate the Mediterranean style dietary adherence. Alternate MedDiet was originally based on 14-item questionnaire; we adjusted it to our population (max 13 points).

RESULTS

We enrolled 226 consecutive outpatients (age 61.7±10.9 years, 72% males). The median duration after revascularization was 60 months. A total of 112 (49.6%) patients had previous percutaneous coronary intervention (PCI), 77 (34.1%) had coronary by-pass graft surgery (CABG), and 36 (15.9%) had both revascularization procedures. The median MedDiet score was 6. Patients were stratified into two subgroups (MedDiet score ≥7 vs. <7). A total of 61 (26.9%) patients had MedDiet score ≥7. By univariate analysis, good MedDiet scores were associated with older age, waist circumference, body mass index, high education level, regular follow-up, duration after first revascularization and revascularization with CABG+PCI. In the multivariate analysis, high education level (P=.002, OR=8.212, 95%CI: 2.155-31.291) and duration after revascularization (P=.034, OR=1.007, 95%CI: 1.001-1.013) were independent predictors of good MedDiet scores.

CONCLUSION

The adherence rate to a healthy diet was low in patients with previous coronary revascularization. MedDiet score seems to be practical and useful item to evaluate the dietary habits in outpatient setting. Mediterranean diet adherence rates were associated with high education level, and duration after revascularization.

Shall We Inject Superficial or Deep to the Plantar Fascia? An Ultrasound Study of the Treatment of Chronic Plantar Fasciitis

We compared the effectiveness of ultrasound (US)-guided corticosteroid, injected superficial or deep to the fascia, in patients with plantar fasciitis. Thirty patients (24 females [75%] and 6 males [25%]) with unilateral chronic plantar fasciitis were divided into 2 groups according to the corticosteroid injection site: superficial (n = 15) or deep (n = 15) to the plantar fascia. Patient heel pain was measured using a Likert pain scale and the Foot Ankle Outcome Scale (FAOS) for foot disability, evaluated at baseline and repeated in the first and sixth weeks. The plantar fascia and heel pad thicknesses were assessed on US scans at baseline and the sixth week. The groups were similar in age, gender, and body mass index (p > .05 for all). Compared with the baseline values, the Likert pain scale (p < .001 for all) and FAOS subscale (p < .01 for all) scores had improved at the first and sixth week follow-up visits in both groups. Although the plantar fascia thickness had decreased significantly in both groups at the sixth week (p < .001 for both), the heel pad thickness remained unchanged (p > .05 for both). The difference in the FAOS subscales (pain, p = .002; activities of daily living, p = .003; sports/recreational activities, p = .008; quality of life, p = .009) and plantar fascia thickness (p = .049) showed better improvement in the deep than in the superficial injection group. US-guided corticosteroid injections are safe and effective in the short-term therapeutic outcome of chronic plantar fasciitis. Additionally, injection of corticosteroid deep to the fascia might result in greater reduction in plantar fascia thickness, pain, and disability and improved foot-related quality of life.

Experiences with a modified preauricular mini incision with subdermally dissection in condylar and subcondylar fractures of the mandible

OBJECTIVE

Condylar and subcondylar fractures (CSFs) are among the most common mandible fractures. If reduction of these fractures is not carried out correctly, serious complications can result, including infection, damage to temporomandibular joint (TMJ) function, malocclusion, nonunion, malunion, and ankylosis of the TMJ.

METHODS

We used a preauricular, mini-incision, open technique (PMIOT) for CSF of the mandible. 66 patients (48 males, 18 females), with a total of 72 CSFs of the mandible, were repaired with PMIOT between 2011 and 2016. Average age was 37.8 years (range: 8-78). CSFs were located on the right side, left side, and bilaterally in 21, 27 and six patients, respectively. We used only one mini incision of length 2 cm for non-displaced subcondylar fractures. However, we had to perform a second mini incision for condylar fractures displaced by more than 45°, where subcondylar fractures overlapped, or where there was deep surgical exposure and difficulty with reduction.

RESULTS

No early complications, such as bleeding, hematoma, seroma, infection, or parotid fistula, were seen in any patients. Temporary facial nerve paresis was reported in three patients, but these recovered spontaneously with conservative treatment within 15 days. Permanent facial nerve paralysis occurred in none of the patients.

CONCLUSION

We believe that PMIOT is an effective, reliable, and feasible method for repair of CSF. It does not need any expensive and sophisticated tools, and has low complication rates. The mini incision used in our technique results in both a hidden scar and protection of essential structures in the region.

The ameliorative effects of Ginkgo biloba on apoptosis, LH-R expression and sperm morphology anomaly in testicular torsion and detorsion

Torsion/detorsion (T/D) induces testicular damages in both germinal epithelial and interstitial tissues. Ginkgo biloba extract (GbE) exerts antioxidant and free radical scavenger. We investigated the effect of GbE on testicular tissues, Leydig and sperm cells in rats injured with T/D. Twenty-eight Wistar albino rats were randomly assigned into four groups (Control, GbE, Treatment: T/D+GbE, T/D). T/D performed to the rats in torsion, treatment received GbE (50 mg/kg) 1 hr before T/D, GbE group received only GbE (50 mg/kg) and control was defined as sham group. After T/D, the testes along with epididymis were removed and processed. LH-R expression, apoptosis, sperm morphology and histopathological damage scores were determined for each group. Testicular T/D caused significant increases in apoptosis and sperm morphology anomaly, and a significant decrease in Johnsen's testicular biopsy scores, LH-R expression of Leydig cell and normal sperm cell count. GbE ameliorated testicular histopathology and caused significant increases in LH-R expression, normal sperm cell count in the treated and particularly GbE group. Consequently, GbE may prevent testicular injury and enhance Leydig and sperm cell activity following both T/D and normal situation owing to its antioxidant, anti-apoptotic, free radical scavenger and anti-inflammatory effects.

Differential efficiency of transcutaneous electrical nerve stimulation in dominant versus nondominant hands in fibromyalgia: placebo-controlled functional near-infrared spectroscopy study

Using functional near-infrared spectroscopy (fNIRS), modulation of hemodynamic responses by transcutaneous electrical nerve stimulation (TENS) during delivery of nociceptive stimulation was investigated in fibromyalgia (FM) patients and healthy controls for both hands. Two experiments were conducted: (1) median nerve stimulation with TENS and (2) painful stimulation using electronic von Frey filaments with TENS/placebo TENS. Mean [Formula: see text] brain activity was compared across groups and conditions using factorial ANOVA. Dominant (right) hand stimulation indicated significant interactions between group and condition in both hemispheres. Post hoc results revealed that FM patients showed an increased activation in "pain + TENS" condition compared to the "pain + placebo TENS" condition while the brain activity patterns for these conditions in controls were reversed. Left-hand stimulation resulted in similar TENS effects (reduced activation for "pain + TENS" than "pain + placebo TENS") in both groups. TENS effects in FM patients might be manipulated by the stimulation side. While the nondominant hand was responsive to TENS treatment, the dominant hand was not. These results indicate that stimulation side might be an effective factor in FM treatment by using TENS. Future studies are needed to clarify the underlying mechanism for these findings.
