Monte LDL, Ocáriz RC, Bustorff-Silva JM, Pegolo PTDC, Guerra-Junior G, Miranda ML. Evaluation of the level of information of pediatricians about the diagnosis and management of cryptorchidism. J Pediatr (Rio J) 2024:S0021-7557(24)00072-X. [PMID: 38996811 DOI: 10.1016/j.jped.2024.06.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2023] [Revised: 06/03/2024] [Accepted: 06/04/2024] [Indexed: 07/14/2024] Open
Abstract
OBJECTIVE Evaluate the level of information of pediatricians about the diagnosis and management of cryptorchidism. METHOD A cross-sectional observational study was conducted using a form via the "Google Forms" platform. The study population included pediatricians and pediatric residents associated with the Brazilian Society of Pediatrics. Seven hundred twenty-eight responses were recorded and analyzed using IBM SPSS v21. RESULTS 728 valid responses were obtained. Of these answers, only 20.5 % answered that the physical examination was sufficient for the diagnosis, and 79.4 % responded that they requested ultrasound as the best test to aid in diagnosing cryptorchidism. When questioned about the ideal age for referring a patient with cryptorchidism, the survey recorded 56.3 % of the responses defending the correct age as six months old, 30.2 % shortly after birth, and 13.2 % at two years old. Other topics were addressed in the form, such as the frequency of evaluation of testicular position and investigation for DDS, among others. Still, the answers to these questions were compatible with current manuals and guidelines on cryptorchidism. CONCLUSION It is evident that the understanding of the professionals consulted about the diagnosis and management of cryptorchidism needs to be updated with the current practices adopted and that pediatricians, in general, must maintain periodic programs on this subject. Therefore, this topic should be part of a continuing education program with pediatric surgery.

Posterior Approach and Inferior Capsulotomy in Bipolar Hemiarthroplasty for Femoral Neck Fractures: Comparison with Superior Capsulotomy. Clin Orthop Surg 2024; 16:374-381. [PMID: 38827757 PMCID: PMC11130618 DOI: 10.4055/cios23259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 09/12/2023] [Accepted: 09/12/2023] [Indexed: 06/04/2024] Open
Abstract
Background Hemiarthroplasty is frequently used to treat displaced femoral neck fractures in elderly patients, but it has a higher risk of postoperative dislocation. We introduced the posterior approach and inferior capsulotomy (PAICO) to enhance joint stability after bipolar hemiarthroplasty for femoral neck fracture. We evaluated whether the PAICO would have a lower dislocation rate than the conventional posterior approach with superior capsulotomy. Methods From January 2021 to December 2021, we prospectively recruited 25 patients (25 hips) aged 50 years or older who underwent bipolar hemiarthroplasty for femoral neck fractures due to low-energy trauma as the PAICO group. We compared the PAICO group with a historical control group who had undergone hemiarthroplasty in 7 institutes between 2010 and 2020. The primary endpoint was dislocation within 1 year after the surgery. We compared data from the PAICO group with the data from the historical control group from the Korean Hip Fracture Registry which was carried out in South Korea. Results A total of 25 patients (25 hips) were enrolled in the present study; 3,477 patients (3,571 hips) who underwent bipolar hemiarthroplasty were reviewed as the historical control group. In the PAICO group, we observed no dislocation, whereas the dislocation rate in the control group was 1.3%. Conclusions In patients with displaced femoral neck fractures, the PAICO approach demonstrated comparable results in operation time and complication rates when compared to bipolar hemiarthroplasty using superior capsulotomy. Notably, there were no observed cases of dislocation among patients who underwent the PAICO approach. We recommend this PAICO approach to surgeons using the posterior approach, hoping to prevent dislocation in bipolar hemiarthroplasty.

Non-anatomical liver resection for hepatocellular carcinoma: the SegSubTe classification to overcome the problem of heterogeneity. Hepatobiliary Pancreat Dis Int 2024; 23:265-271. [PMID: 36775688 DOI: 10.1016/j.hbpd.2023.02.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 01/18/2023] [Indexed: 02/14/2023]
Abstract
BACKGROUND The superiority of anatomical resection (AR) vs. non-anatomical resection (NAR) in the surgical management of hepatocellular carcinoma (HCC) is debated. ARs are well-defined procedures, whereas the lack of NAR standardization results in heterogeneous outcomes. This study aimed to introduce the SegSubTe classification for NAR detailing the appropriateness of the level of surgical section of the Glissonean pedicles feeding the tumor. METHODS A single-center retrospective analysis of pre- and postoperative imaging of consecutive patients treated with NAR for single HCC between 2012 and 2020 was conducted. The quality of surgery was assessed classifying the type of vascular supply and the level of surgical section (segmental, subsegmental or terminal next to the tumor) of vascular pedicles feeding the HCCs; then, the population was divided in "SegSubTe-IN" or "SegSubTe-OUT" groups, and the tumor recurrence and survival were analyzed. RESULTS Ninety-seven patients who underwent NAR were included; 76% were SegSubTe-IN and 24% were SegSubTe-OUT. Total disease recurrence, local recurrence and cut-edge recurrence in the SegSubTe-IN vs. SegSubTe-OUT groups were 50% vs. 83% (P = 0.006), 20% vs. 52% (P = 0.003) and 16% vs. 39% (P = 0.020), respectively. SegSubTe-OUT odds ratio for local recurrence was 4.1 at univariate regression analysis. One-, three-, and five-year disease-free survival rates in the SegSubTe-IN vs. SegSubTe-OUT groups were 81%, 58% and 35% vs. 46%, 21% and 11%, respectively (P < 0.001). CONCLUSIONS The SegSubTe classification is a useful tool to stratify and standardize NAR for HCC, aiming at improving long-term oncological outcomes and reducing the heterogeneity of quality of NAR for HCC.

Abstract
Purpose To report a case of a refractory foveal microaneurysm (MA) that was successfully treated by use of a new surgical procedure. Observations This study involved a 79-year-old female with an active foveal MA associated with branch retinal vein occlusion in her left eye. Despite anti-vascular endothelial growth factor treatments, the MA remained active without closure, and best-corrected visual acuity (VA) gradually decreased from 20/20 to 20/200. After our new surgical procedure was explained in detail to the patient, written informed consent was obtained from the patient and the surgery was performed. Briefly, following pars plana vitrectomy, the internal limiting membrane in her left eye was peeled and the retina of the external wall of the MA was then gently incised. The exposed MA was then directly grabbed and pulled up onto the retina using 27-gauge microforceps, and photocoagulation was performed. At 3-months postoperative, closure of the MA and improvement in the retinal findings were observed, and best-corrected VA improved to 20/67. Conclusions and importance We report a case of a refractory foveal MA that was successfully treated with a novel surgical technique that closed the MA, avoided thermal damage to the surrounding tissue, and resulted in improved postoperative VA.

Abstract
Background Spinal cord injury (SCI) is a severe impairment of the central nervous system, leading to motor, sensory, and autonomic dysfunction. The present study investigates the efficacy of the polyethylene glycol (PEG)-mediated spinal cord fusion (SCF) techniques, demonstrating efficacious in various animal models with complete spinal cord transection at the T10 level. This research focuses on a comparative analysis of three SCF treatment models in beagles: spinal cord transection (SCT), vascular pedicle hemisected spinal cord transplantation (vSCT), and vascularized allograft spinal cord transplantation (vASCT) surgical model. Methods Seven female beagles were included in the SCT surgical model, while four female dogs were enrolled in the vSCT surgical model. Additionally, twelve female dogs underwent vASCT in a paired donor-recipient setup. Three surgical model were evaluated and compared through electrophysiology, imaging and behavioral recovery. Results The results showed a progressive recovery in the SCT, vSCT and vASCT surgical models, with no statistically significant differences observed in cBBB scores at both 2-month and 6-month post-operation (both P>0.05). Neuroimaging analysis across the SCT, vSCT and vASCT surgical models revealed spinal cord graft survival and fiber regrowth across transection sites at 6 months postoperatively. Also, positive MEP waveforms were recorded in all three surgical models at 6-month post-surgery. Conclusion The study underscores the clinical relevance of PEG-mediated SCF techniques in promoting nerve fusion, repair, and motor functional recovery in SCI. SCT, vSCT, and vASCT, tailored to specific clinical characteristics, demonstrated similar effective therapeutic outcomes.

Abstract
PURPOSE Surgical manipulation of the lungs increases the number of circulating tumor cells and the subsequent risk of metastasis in patients with lung cancer. This study investigated whether or not ligating the tumor-draining pulmonary vein first during lobectomy could improve the prognosis of these patients. METHODS We retrospectively evaluated patients who underwent curative lobectomy for solitary nonsmall-cell lung carcinoma between January 2012 and December 2016. We divided the patients into the vein-first group, in which all associated pulmonary veins were dissected and severed before cutting the pulmonary artery, bronchus, or pulmonary fissure, and the other procedure group. RESULTS Overall, we included 177 and 413 patients in the vein-first and other procedure groups, respectively. Propensity score matching yielded 67 pairs of patients. The 5-year overall survival (85.6% [95% confidence interval, 77.3-94.8%] vs. 69.4% [58.7-81.9%], P = 0.03%) and recurrence-free survival (73.4% [63.3-85.1%] vs. 53.5% [42.5-67.3%], P = 0.02) were significantly better in the vein-first group than in the other procedure group. The cumulative recurrence rate at 5 years post-surgery was significantly lower in the vein-first group than in the other procedure group (21.7% vs. 38.3%, P = 0.04). CONCLUSION Our study suggests that ligating the pulmonary vein first during lobectomy for lung cancer can improve the overall survival, recurrence-free survival, and cumulative recurrence rate.

Abstract
The aim of this study was to propose a treatment strategy for intraglandular submandibular calculi based on calculus site. Seventy-three consecutive patients with impalpable intraglandular submandibular calculi were enrolled retrospectively. The calculi were classified as either post-hilar type, central type, or superficial type. Treatment approaches included transoral duct slitting (TDS), interventional basket retrieval (IBR), intraductal laser lithotripsy (ILL), and transcervical lithotomy (TCL). Complete calculus removal with gland preservation was achieved in 64 patients (87.7%). The success rate for post-hilar, central, and superficial calculi was 86.4% (51/59), 90.9% (10/11), and 100% (3/3), respectively. The treatment approach applied in patients with treatment success was TDS in 32 cases, IBR in 20, ILL in nine, and TCL in three. During follow-up (median 17.3 months), one patient experienced gland atrophy and three had ductal stenosis; the remaining 60 patients (93.8%, 60/64) had good clinical outcomes. In the eight failure cases operated by TDS, the deeply situated calculi could not be detached despite the parenchymal incision in five cases, while the procedure was ceased due to the patient's inability to cooperate in the other three cases. In the remaining failure case, the submandibular gland was sacrificed after calculus extraction via TCL. Application of the proposed treatment algorithm might help preserve gland function in patients with intraglandular submandibular calculi.

Abstract
BACKGROUND To enhance patient satisfaction, nurses engaged in preoperative care must possess a comprehensive understanding of the most up-to-date evidence. However, there is a notable dearth of relevant information regarding the current status of preoperative care satisfaction and its impact, despite a significant rise in the number of patients seeking surgical intervention with complex medical requirements. OBJECTIVE To assess patient satisfaction with preoperative nursing care and its associated factors in surgical procedures of, 2023. METHODS A cross-sectional study was conducted, and the data was collected from the randomly selected 468 patients who had undergone surgery during the study period. The collected data was entered into Epidata version 3.1 and analyzed using SPSS version 25 software. RESULTS The complete participation and response of 468 participants resulted in a response rate of 100%. Overall patient satisfaction with preoperative nursing care was 79.5%. Sex (Adjusted odds ratio (AOR): 1.14 (95% confidence interval (CI): 0.21-2.91)), payment status for treatment (AOR: 1.45 (95% CI: 0.66-2.97)), preoperative fear and anxiety (AOR: 1.01, 95% CI: 0.49-2.13)), patient expectations (AOR: 3.39, 95% CI: 2.17-7.11)), and preoperative education (AOR: 1.148, 95% CI: 0.54-2.86)) exhibited significant associations with patient satisfaction with preoperative nursing care. CONCLUSION It is important to exercise caution when interpreting the level of preoperative nursing care satisfaction in this study. The significance of preoperative nursing care satisfaction lies in its reflection of healthcare quality, as even minor deficiencies in preoperative care can potentially lead to life-threatening complications, including mortality. Therefore, prioritizing the improvement of healthcare quality is essential to enhance patient satisfaction.

Abstract
BACKGROUND Despite the guidelines recommending thyroid lobectomy, many papillary thyroid microcarcinoma (PTMC) patients still undergo total thyroidectomy. PTMC's optimal treatment remains unclear. We aimed to determine whether total thyroidectomy improves outcomes compared to less extensive surgery. METHODS We analyzed 6064 PTMC adult patients from the Surveillance, Epidemiology, and End Results (SEER) database (2000-2019) who underwent either total thyroidectomy (n = 3652) or less extensive surgery (n = 2412). Endpoints were overall survival, cancer-specific survival, and recurrence. RESULTS Total thyroidectomy patients had a 5.2 % mortality rate versus 8.1 % with less extensive surgery. Recurrence occurred in 1 (0.03 %) total thyroidectomy patient compared to 24 (1.0 %) less extensive surgery patients (HR 0.07, p = 0.01). Median survival was 8.1 years for total thyroidectomy versus 8.8 years for less extensive surgery. Overall survival favored total thyroidectomy (p = 0.001) but cancer-specific survival did not differ. CONCLUSION Although total thyroidectomy may not improve cancer-specific survival, it lowers recurrence risk and confers an overall survival advantage for PTMC patients. These findings may help guide surgical decisions.

Abstract
The survival outcomes of patients with chest wall sarcomas (CWS) were evaluated after receiving wide excision and chest wall reconstruction by using three-dimensional printed (3DP) implants. The survival outcomes evaluating the effect of 3DP implants for chest wall reconstruction is lacking. Here, forty-nine patients with CWS underwent radical wide excision and chest wall reconstruction using 3DP implants. The surgical data and long-term survival outcomes were collected and analyzed. With a median follow-up of 36 months, the disease-free survival (DFS) and overall survival (OS) were 31.7% and 58.5%, respectively. In addition, the 3-year DFS and OS can be significantly differentiated using the classification criteria of tumor grade, tumor size tumor area. Hence, wide excision and chest wall reconstruction using three-dimensional printed implants are a safe and effective treatment for chest wall sarcoma. The novel classification criteria of tumor size and area have the potential to predict the prognosis of CWS.

Abstract
Myocardial ischemia-reperfusion injury (IRI) after myocardial ischemia, cardiac surgery, or circulatory arrest leads to adverse cardiovascular outcomes. Primarily, no blood flow to the heart causes an imbalance between oxygen demand and supply, namely, ischemia, resulting in damage or dysfunction of the cardiac tissue. Early restoration of blood flow has been established to be the treatment of choice to prevent further tissue injury. Indeed, the use of thrombolytic therapy or primary percutaneous coronary intervention is the most effective strategy for reducing the size of a myocardial infarct and improving the clinical outcome. Unfortunately, restoring blood flow to the ischemic myocardium, named reperfusion, can also contribute to injury. This phenomenon was therefore termed myocardial IRI. Subsequent studies in animal models of acute myocardial infarction suggest that myocardial IRI accounts for up to 50% of the final size of a myocardial infarct. Consequently, many researchers aim to understand the underlying molecular mechanism of myocardial IRI to find therapeutic strategies that ultimately reduce the final infarct size. Despite numerous therapeutic strategies identified in laboratories, no clinical medicine specifically targeting IRI has yet been approved. Therefore, more relevant research is needed to develop promising therapeutic agents. In this respect, we will introduce a solid and reproducible experimental protocol to induce myocardial IRI in mice and test potent drug transfer during this surgical procedure.

Abstract
INTRODUCTION In spite of being inaccurate in terms of suprahyoid dissection, Sistrunk's procedure is the gold-standard technique in the treatment of thyroglossal cyst. Since it was first described in 2014, the modifications introduced by Koempel have allowed for a more reproducible suprahyoid approach. We present our initial experience with this technique. METHODS A retrospective study of patients with thyroglossal cyst undergoing Koempel's technique in our institution from 2021 to 2022 was carried out. Demographic, clinical, and histological data was collected. RESULTS In the study period, 5 patients -3 girls and 2 boys- underwent surgery. Median age and weight were 5 years (2-6) and 16 kg (14-25), respectively. All patients had suffered from previous infections, with 60% having cutaneous fistulization. In 2 patients, surgery was indicated following Sistrunk's procedure as a result of recurrence. Median operating time was 77 minutes (57-110), with the genioglossal muscle plane being identified in the 5 patients. No immediate complications were recorded, and diagnosis of thyroglossal cyst was histologically confirmed in all cases. One of the formerly recurrent patients had recurrence following surgery, but it was subclinical and incidentally diagnosed at control ultrasonography. The remaining patients had no recurrences after a median 8-month (1-12) follow-up period. CONCLUSIONS Koempel's technique allows for a safe and reproducible approach of the suprahyoid segment. It is an attractive option in complicated cases as a result of previous infection or recurrence.

Abstract
Orthotopic models of hepatocellular carcinoma (HCC) consist in the implantation of tumor cells into the liver by direct intrahepatic injection. In this model, tumorigenesis is triggered within the hepatic microenvironment, thus mimicking the metastatic behavior of HCC. Herein, we detail a surgically mediated methodology that allows the reproducible and effective induction of liver-sessile tumors in mice. We enumerate the steps to be followed before and after the surgical procedure, including HCC cell preparation, the quantity of cancer cells to be injected, presurgical preparation of the mice, and finally, postoperative care. The surgical procedure involves laparotomy to expose the liver, injection of cells into the left-lateral hepatic lobe, and closure of the incision with sutures followed by wound clips. We also provide information concerning the subsequent tumor growth follow-up, as well as the application of bioluminescence imaging to monitor tumor development.

Abstract
STUDY DESIGN Retrospective cohort study. PURPOSE This study aimed to develop machine-learning algorithms to predict ambulation outcomes following surgery for spinal metastasis. OVERVIEW OF LITERATURE Postoperative ambulation status following spinal metastasis surgery is currently difficult to predict. The improved ability to predict this important postoperative outcome would facilitate management decision-making and help in determining realistic treatment goals. METHODS This retrospective study included patients who underwent spinal metastasis at a university-based medical center in Thailand between January 2009 and November 2021. Collected data included preoperative parameters and ambulatory status 90 and 180 days following surgery. Thirteen machine-learning algorithms, namely, artificial neural network, logistic regression, CatBoost classifier, linear discriminant analysis, extreme gradient boosting, extra trees classifier, random forest classifier, gradient boosting classifier, light gradient boosting machine, naïve Bayes, K-neighbor classifier, Ada boost classifier, and decision tree classifier were developed to predict ambulatory status 90 and 180 days following surgery. Model performance was evaluated using the area under the receiver operating characteristic curve (AUC) and F1-score. RESULTS In total, 167 patients were enrolled. The number of patients classified as ambulatory 90 and 180 days following surgery was 140 (81.9%) and 137 (82.0%), respectively. The extreme gradient boosting algorithm was found to most accurately predict 180-day ambulatory outcome (AUC, 0.85; F1-score, 0.90), and the decision tree algorithm most accurately predicted 90-day ambulatory outcome (AUC, 0.94; F1-score, 0.88). CONCLUSIONS Machine-learning algorithms were effective in predicting ambulatory status following surgery for spinal metastasis. Based on our data, the extreme gradient boosting and decision tree best predicted postoperative ambulatory status 180 and 90 days after spinal metastasis surgery, respectively.

Abstract
PURPOSE This study aimed to elucidate the difficulty of adjuvant chemotherapy administration in patients with biliary tract carcinoma (BTC). METHODS Clinical data of patients with BTC who underwent curative-intent surgery were retrospectively analyzed. The eligible patients were stratified into two groups according to the presence or absence of adjuvant chemotherapy administration (adjuvant and non-adjuvant groups), and the clinicopathological features were compared between the two groups. The ratios of adjuvant chemotherapy administration were investigated in each surgical procedure. Independent factors associated with no administration of adjuvant chemotherapy were analyzed using multivariate analyses. RESULTS Among 168 eligible patients, 141 (83.9%) received adjuvant chemotherapy (adjuvant group), while 27 (16.1%) did not (non-adjuvant group). The most common surgical procedure was pancreaticoduodenectomy in the adjuvant group, and it was hepatectomy with extrahepatic bile duct resection (BDR) in the non-adjuvant group, respectively. The rate of no adjuvant chemotherapy was significantly higher in patients who underwent hepatectomy with BDR than in those who underwent other surgeries (p < 0.001). The most common cause of no adjuvant chemotherapy was bile leak in 12 patients, which occurred after hepatectomy with BDR in ten patients. Multivariate analyses revealed that hepatectomy with BDR and preoperative anemia were independently associated with no adjuvant chemotherapy (p < 0.001 and p < 0.001, respectively). CONCLUSIONS Hepatectomy with BDR and subsequent refractory bile leak can be the obstacle to adjuvant chemotherapy administration in patients with BTC.

Abstract
INTRODUCTION Transurethral resection of the bladder (TUR-BT) is the standard initial treatment and diagnosis of bladder cancer (BC). Of note, upstaging into muscle-invasive disease (MIBC) during re-resection occurs in a significant proportion of patients. This study aimed to define risk factors at initial TUR-BT for upstaging. METHODS TUR-BT between 2009 and 2021 were retrospectively screened (n = 3,237). We included patients with visible tumors that received their primary and re-TUR-BT at our institution. Upstaging was defined as pathological tumor stage progression into MIBC at re-TUR-BT. Clinicopathological variables were analyzed for the impact on upstaging. RESULTS Two hundred and sixty-six patients/532 TUR-BTs were included in the final analysis. Upstaging occurred in 7.9% (21/266) patients. Patients with upstaging presented with stroma-invasive and papillary non-muscle-invasive BC at primary resection in 85.7% (18/21) and 14.3% (3/21), respectively. Detrusor muscle at primary TUR-BT was significantly less present in patients with upstaging (4.1 vs. 95.9%; p < 0.001). After multivariate analysis, solid tumor configuration (HR: 4.17; 95% CI: 1.23-14.15; p = 0.022) and missing detrusor muscle at initial TUR-BT (HR: 3.58; 95% CI: 1.05-12.24; p = 0.043) were significant risk factors for upstaging into MIBC. CONCLUSIONS The current study defined two major risk factors for upstaging: missing detrusor muscle and solid tumor configuration. We propose that a second resection should be performed earlier if these risk factors apply.

Zhang K, Xu H, Du L, Liu Y, Xu B. Application of self-anchored lateral lumbar interbody fusion in lumbar degenerative diseases. BMC Musculoskelet Disord 2023; 24:836. [PMID: 37872610 PMCID: PMC10594783 DOI: 10.1186/s12891-023-06974-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 10/17/2023] [Indexed: 10/25/2023] Open
Abstract
STUDY DESIGN This is a retrospective study. OBJECTIVE The aim of the study was to evaluate the efficacy of self-anchored lateral lumbar interbody fusion (SA-LLIF) in lumbar degenerative diseases. METHODS Forty-eight patients with lumbar degenerative disease between January 2019 and June 2020 were enrolled in this study. All patients complained of low back and leg pain, which were aggravated during standing activities and alleviated or disappeared during lying. After general anesthesia, the patient was placed in the right decubitus position. The anterior edge of the psoas major muscle was exposed through an oblique incision of approximately 6 cm, using an extraperitoneal approach. The psoas major muscle was then properly retracted dorsally to expose the disc. After discectomy, a suitable cage filled with autogenous bone graft from the ilium was implanted. Two anchoring plates were inserted separately into the caudal and cranial vertebral bodies to lock the cage. Clinical efficacy was evaluated using the visual analog scale (VAS) and Oswestry Disability Index (ODI). Lumbar lordosis, intervertebral disc height, spondylolisthesis rate, cage subsidence and fusion rate were also recorded. RESULTS A total of 48 patients were enrolled in this study, including 20 males and 28 females, aged 61.4 ± 7.3 (range 49-78) years old. Surgery was successfully performed in all patients. Lumbar stenosis and instability were observed in 22 cases, disc degenerative disease in eight cases, degenerative spondylolisthesis in nine cases, degenerative scoliosis in six cases, and postoperative revision in three cases. In addition, five patients were diagnosed with osteoporosis. The index levels included L2-3 in three patients, L3-4 in 13 patients, L4-5 in 23 patients, L2-4 in three patients, and L3-5 in six patients. The operation time was 81.1 ± 6.4 (range 65-102) min. Intraoperative blood loss was 39.9 ± 8.5 (range 15-72) mL. No severe complications occurred, such as nerve or blood vessel injuries. The patients were followed up for 11.7 ± 2.3 (range 4-18) months. At the last follow-up, the VAS decreased from 6.2 ± 2.3 to 1.7 ± 1.1, and the ODI decreased from 48.4% ± 11.2% to 10.9% ± 5.5%. Radiography showed satisfactory postoperative spine alignment. No cage displacement was found, but cage subsidence 2-3 mm was found in five patients without obvious symptoms, except transient low back pain in an obese patient. The lumbar lordosis recovered from 36.8° ± 7.9° to 47.7° ± 6.8°, and intervertebral disc height recovered from 8.2 ± 2.0 mm to 11.4 ± 2.5 mm. The spondylolisthesis rate decreased from 19.9% ± 4.9% to 9.4% ± 3.2%. The difference between preoperative and last follow-up was statistically significant (P<0.05). CONCLUSION SA-LLIF can provide immediate stability and good results for lumbar degenerative diseases with a standalone anchored cage without posterior internal fixation.

Abstract
Perioperative blood transfusion is costly and raises safety concerns. We developed and validated a model for predicting minor, moderate, or major transfusion given to patients during on-pump cardiac procedures based on two centers' database. Model performance incorporating 7 variables on the development set had an AUC of 0.803 [95% CI, 0.790-0.815] for minor transfusion; moderate transfusion, giving an AUC of 0.822 (95% CI, 0.803-0.841); and major transfusion, giving an AUC of 0.813 (95% CI, 0.759-0.866). Model performance on the validation set had an AUC of 0.739 (95% CI 0.714-0.765), 0.730 (95% CI 0.702-0.758), and 0.713 (95% CI 0.677-0.749), respectively. A model based entirely on readily available electronic health records can accurately predict intraoperative minor, moderate, or major transfusion and provide individualized transfusion risk profiles before surgery among those on-pump cardiac surgical patients, and may help guide patient management.

Abstract
Excessive scarring is the main cause of surgical failure in glaucoma filtration surgery. S58 has been shown to have an excellent antifibrotic effect but its duration of action is not sufficient to achieve the desired antiscarring effect. In this study, a light-cured bioadhesive hydrogel composed of GelMA and oxidized dextran (ODex), namely, GelDex, was used to load S58 (GelDex-S58). The microscopic morphology of GelDex-S58 appeared to be a porous structure with good slow-release properties and suitable degradation time. Cell Counting Kit-8, cell scratch and transwell assays showed that GelDex-S58 significantly reduced TGF-β-induced fibroblast proliferation, increased migration and invasion ability. In in vivo studies, GelDex-S58 treatment prolonged follicular retention, reduced mean intraocular pressure, and significantly reduced collagen deposition and α-SMA expression levels in the conjunctival tissue compared to treatment with S58 alone. In conclusion, GelDex-S58 could reduce scar formation after glaucoma filtration surgery.

Abstract
Fractional CO2 laser, as a typical ablative laser, has been used to assist in the treatment of many skin diseases, such as photoaging, atrophic scar, hypertrophic scar, superficial pigmentation, vitiligo, and so on. However, the dynamic changes in skin function after fractional CO2 laser treatment are still unclear. This study explored the changes in local skin function and possible regulatory mechanisms after fractional CO2 laser treatment for 1, 3, 5, and 7 days through transcriptome high-throughput sequencing. The results showed that fractional CO2 laser tended to transform the "lesions" into "normal skin", regulate the skin barrier, coordinate the rearrangement of collagen, enhance the local microvascular circulation, activate the immune system to secrete a large number of cytokines, and act as an auxiliary tool to assist drug transport. In conclusion, according to the basic principle of destruction before reconstruction, fractional CO2 laser plays a key role of balancer in skin reconstruction.

The inter-prefectural regional disparity of healthcare resources and representative surgical procedures in orthopaedics and general surgery: a nationwide study in Japan during 2015-2019. BMC Musculoskelet Disord 2023; 24:726. [PMID: 37700283 PMCID: PMC10496376 DOI: 10.1186/s12891-023-06820-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/15/2022] [Accepted: 08/22/2023] [Indexed: 09/14/2023] Open
Abstract
BACKGROUND Few reports have examined the localized regional disparity in representative surgical procedures in orthopaedics and general surgery globally. This study aimed to clarify the inter-prefectural regional disparity and relationships between healthcare resources and representative surgical procedures using a nationwide database in Japan. METHODS The number of medical specialists in orthopaedics, general surgery, and anaesthesiology, as well as the number of hospitals, and the incidence of representative surgical procedures in orthopaedics and general surgery were evaluated annually per 100,000 inhabitants/people by prefecture in Japan during 2015-2019. Medium-sized regional disparities were evaluated using the Gini coefficient. Correlation coefficients were calculated for the defined variables and ageing rate. We also compared the urban and rural regional disparities in all study variables. RESULTS The annual average number/incidence and Gini coefficients were 110.6 and 0.11 for femur fracture surgery, 106.3 and 0.09 for cholecystectomy, 14.2 and 0.11 for orthopaedic surgeon specialists, 17.6 and 0.09 for general surgeon specialists, 5.9 and 0.13 for anaesthesiology specialists, and 8.1 and 0.21 for hospitals, respectively. The correlation coefficients by the incidence of femur fracture surgery were 0.74 for orthopaedic surgeon specialists (p < 0.001), 0.63 for hospitals (p < 0.001), and 0.62 for the ageing rate (p < 0.001); those by the incidence of cholecystectomy were 0.60 for general surgeon specialists (p < 0.001) and 0.59 for hospitals (p < 0.001). The number/incidence of orthopaedic surgeon specialists, hospitals, femur fracture surgery, and cholecystectomy, as well as the ageing rate, were significantly higher in rural prefectures than in urban prefectures (p < 0.05). CONCLUSIONS Inter-prefectural regional disparity was small, although certain items were unevenly distributed in the rural prefectures, which is contrary to our expectations. Higher prevalence was recognised in rural prefectures due to the higher ageing rate; however, supply and demand are balanced. This study provides basic data for healthcare policy development in a medium-sized community. LEVEL OF EVIDENCE III.

Preoperative flexion contracture does not affect outcome in total knee arthroplasty: A case-control study of 2,634 TKAs. Orthop Traumatol Surg Res 2023; 109:103592. [PMID: 36924881 DOI: 10.1016/j.otsr.2023.103592] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 01/04/2023] [Accepted: 01/18/2023] [Indexed: 03/17/2023]
Abstract
BACKGROUND One issue in total knee arthroplasty (TKA) is management of preoperative flexion contracture, which may be associated with poor functional outcome. AIM The aim of this study was to compare functional results in TKA with or without preoperative flexion contracture, treated according to a standardized algorithm of tissue release and bone cut. PATIENTS AND METHOD A single-center retrospective case-control study was performed on prospectively collected data for the period 1987-2016. Patients with >10̊ flexion contracture were assigned to the "contracture" group and associated to a selected control group at a ratio of 1:4. Clinical analysis used pre and post-operative International Knee Society (IKS) scores. The significance threshold was set at p<0.05. RESULTS Eight hundred and forty-nine cases and 3,304 controls were included, comprising a total of 2,838 male and 1,315 female participants. Mean preoperative extension deficit was 13̊±6̊ in the contracture group and 1̊±2̊ in controls. Preoperative IKS total and functional scores were significantly poorer in the contracture group (38±18 and 54±20) than in controls (52±16 and 59±19) (p<0.001). Postoperatively, the two groups did not significantly differ in IKS functional score (77±22 vs. 79±21, p=0.143). There were differences in IKS knee score (87±12 vs. 88±13, p=0.006) and maximal flexion (114̊±14̊ vs. 119̊±13̊, p<0.0001) that were statistically, but not clinically, significant. DISCUSSION A systematic standardized algorithm for surgical treatment of flexion contracture during primary total knee arthroplasty provided clinical outcomes similar to those of patients without preoperative flexion contracture. LEVEL OF EVIDENCE III; case-control study.

Abstract
BACKGROUND Transoral robotic surgery (TORS) has renovated the surgical management of oropharyngeal squamous cell carcinoma (OPSCC), allowing a minimally invasive surgical approach with optimal oncological outcomes. The recent introduction of the da Vinci Single Port (SP) system resulted in a considerable improvement of TORS technique. METHODS In this video, we illustrate the transoral robotic lateral oropharyngectomy performed with the da Vinci SP system in a 50-year-old male patient suffering from a p16+ oropharyngeal squamous cell carcinoma cT4N1M0. RESULTS The transoral robotic lateral oropharyngectomy is illustrated step by step. The structures encountered during the resection are described, and the surgical margins are defined based on anatomical landmarks. The most critical regions encountered during resection are pointed out, and the tip and tricks of this surgery are reported. CONCLUSIONS A step-by-step transoral lateral oropharyngectomy is described to increase its reproducibility. The da Vinci SP system owns various benefits for performing transoral lateral oropharyngectomy due to the increased maneuverability in the narrower oral cavity working spaces.

Abstract
BACKGROUND Idarucizumab has been approved to reverse the anticoagulant effect of dabigatran. However, there is little knowledge of the effectiveness and safety of idarucizumab in daily practice. AIMS This systematic review and meta-analysis aims to evaluate the use, effectiveness and outcomes of idarucizumab. METHODS A systematic literature search was performed up to September 8th 2022. Original studies including patients prescribed idarucizumab, evaluating prescription indications, prescription appropriateness, haemostatic efficacy and/or the occurrence of adverse events were eligible. Case-reports and studies performed in patients ≤18 years or in healthy volunteers were excluded. Study selection and data extraction were performed by two independent reviewers. Pooled estimates were calculated using the random-effects model, after Freeman-Tukey double-arcsine transformation. RESULTS Thirty studies comprising 3602 patients were included. Idarucizumab was prescribed for bleeding (63.1 %, 95%CI 57.0 %-69.0 %), invasive procedures (30.5 %, 95%CI: 24.1 %-37.2 %), to enable thrombolysis (range: 2.0 %-27.3 %), dabigatran intoxication without bleeding (range: 3.6 %-7.0 %) or unspecified reasons (range: 0.4 %-18.8 %). Overall, 2.8 % (95%CI 0.5 %-6.2 %) of prescription indications were reported to be inappropriate upon post-hoc evaluation. Hemostatic effectiveness was achieved in 77.7 % (95%CI 66.7 %-87.2 %) and peri-procedural haemostasis was normal in 98.5 % (95%CI 86.6 %-100 %) of patients. The pooled incidences of all-cause mortality and thromboembolic events at any follow-up duration were 13.6 % (95%CI 9.6 %-17.9 %) and 2.0 % (95%CI 0.8 %-3.4 %), respectively. CONCLUSION Idarucizumab was mainly prescribed in the setting of bleeding. The reported hemostatic effectiveness was good, especially perioperatively, and the incidence of thromboembolic events was low. Patients with dabigatran-associated bleeding or requiring an urgent procedure nonetheless face a high mortality risk.
