Anatomic Variations and Malformations as Rare Causes of Median Nerve Compression in Adults: A Narrative Review.

OBJECTIVE: The median nerve can become compressed at multiple points in the arm, causing carpal tunnel-, pronator-, anterior interosseous-, or lacertus syndrome. Anatomical variations are potential reasons of persisting or recurrent symptoms of median nerve compression and are often recognized late. The objective of this study is to provide a comprehensive list of rare anatomical variations and malformations causing median nerve compression. METHODS: A total of 62 studies describing median nerve compression due to an anatomical structure in adults published from 2000 in English were included. The findings were: 35 tenomuscular, 16 vascular causes, and 4 cases with nerve involvement. Only 1 osseous and 18 combined anomalies caused compression. In 18 cases, the anomaly was found in the proximal forearm. RESULTS: In 44 cases, the median nerve was surgical released and 35 anomalies were completely resected. Persistent or recurrent symptoms were present in 13 cases. During follow-up, 1 case of recurrence was reported.Standard operative option for median nerve compression consists of an open median nerve release. CONCLUSIONS: In case of persistent or recurrent carpal tunnel syndrome, unilateral symptoms, the presence of a palpable mass, manifestation of symptoms at young age and pain in the forearm or upper arm, the surgeon has to rule out the presence of an anatomical anomaly. Complete resection of the anomaly is not always necessary. The surgeon should be aware of potential anomalies to avoid inadvertent damage at surgery.

The Impact of Resident Postgraduate Year Involvement in Body-Contouring and Breast Reduction Procedures: A Comprehensive Analysis of 9638 Patients.

Given the rising popularity in body-contouring procedures (BCPs) in the United States, it is important to assess the currently unknown association between resident involvement and postoperative complications. As such, the aim of this study was to evaluate the impact of resident involvement on outcomes in BCPs using a large national database. METHODS: A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database was performed (2006-2012) to identify patients undergoing BCPs, using relevant Current Procedural Terminology codes. Outcome measures included postoperative complications, hospital length of stay, and operation time.Multivariate regression models were used to assess the impact of resident involvement and resident experience on outcomes. RESULTS: A total of 9638 cases were identified, of which 3311 involved resident participation.Resident involvement was associated with significantly higher rates of complications (7.8% vs 4.4%; P = 0.003) and longer operation times (180.7 vs 171.9 minutes; P = 0.005). For each year increase of resident postgraduate year, there was a significant decrease in odds of complications (odds ratio, 0.906; P = 0.013) and operative time (-2.7 minutes; P = 0.001). CONCLUSIONS: Resident involvement in BCPs was associated with an increased rate of overall complications in a large, national database. However, the clinical significance of these outcomes may be debated. Increased postgraduate year experience as a surgical resident was inversely associated with overall complications. Guided resident autonomy and earlier exposure to BCPs could lead to an optimization of clinical outcomes and resident education.

Reconstruction of Mohs Defects Located in the Head and Neck.

BACKGROUND: Defects following Mohs micrographic surgery (MMS) can range in size from small defects requiring linear closure to large defects needing flap coverage. Reconstruction is dependent on defect size and facial aesthetic unit involvement. The aim of this study was to review the types of facial reconstruction per aesthetic unit involvement and describe their outcomes. METHODS: All data were retrieved for patients ≥18 years who underwent multidisciplinary treatment including dermatological MMS and plastic surgical reconstruction at a single tertiary hospital center (2001-2017). Patient characteristics, tumor pathology, surgical specifics, reconstructive modalities, and surgical outcomes were analyzed. RESULTS: A total of 418 patients were included. Patients were predominantly White, non-Hispanic (97%) and female (58%) with a mean age of 60 ±â€Š13.9 years. Tumor pathology was predominantly basal cell carcinoma in 73% of all cases followed by squamous cell carcinoma in 14%. The nasal aesthetic unit was mostly affected (50%). Local advancement flaps and different types of grafts were used in 51% and 25% of reconstructions, respectively. Complications were observed in 3% and local cancer recurrence in 4% of the patients. Scar revision was needed in 6% of the patients. CONCLUSION: Reconstruction of facial defects after Mohs micrographic surgery can be challenging due to its technical complexity and aesthetic implications. There were differences in complications in reconstructions performed within the same day versus 1 week, with a majority of complications occurring within same-day Mohs reconstructions. A multidisciplinary structured approach, which incorporates patient-reported outcomes, may be needed to optimize surgical results.

The Role of Topical Vitamin E in Scar Management: A Systematic Review.

BACKGROUND: The practice of prescribing vitamin E after surgery for scar prevention and treatment is widespread and increasingly popular among both the public and clinicians. However, very little evidence exists for this "ritual." OBJECTIVES: This review was undertaken to critically analyze the current literature about the effect of vitamin E on treating scars. METHODS: The Cochrane, Medline, and PubMed databases were searched based on the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P). The studies and levels of recommendation were graded according to the American Society of Plastic Surgeons (ASPS) criteria. Only prospective studies were included. RESULTS: Only six studies met the inclusion criteria. Of these six included studies, three reported a significant improvement in the cosmetic appearance of scars when using vitamin E: one study used topical vitamin E in white children as monotherapy, and two studies used vitamin E in an adult population as combination therapy. The other three selected studies showed no significant improvement in scar appearance when using topical vitamin E as monotherapy. Two of the six included studies reported adverse events of vitamin E application: contact dermatitis and increased incidence of itching and rash. CONCLUSIONS: We conclude that there is not yet sufficient evidence that monotherapy with topical vitamin E has a significant beneficial effect on scar appearance to justify its widespread use. Further prospective studies with vitamin E monotherapy and/or combination therapy are warranted to draw better conclusions regarding the value of vitamin E in the management of scar healing. LEVEL OF EVIDENCE: 2 Therapeutic.

Rare Tumors Causing Median Nerve Compression in Adults-A Narrative Review.

The median nerve can be compressed due to a tumor along the course of the median nerve, causing typical compression symptoms or even persistence or recurrence after an operation. The aim of this review is to provide a comprehensive overview of rare tumors described in recent publications that cause median nerve compression and to evaluate treatment options. The PubMed, Embase, and Web of Science databases were searched for studies describing median nerve compression due to a tumor in adults, published from the year 2000 and written in English. From 94 studies, information of approximately 100 patients have been obtained. Results The rare tumors causing compression were in 32 patients located at the carpal tunnel, in 21 cases in the palm of the hand, and 28 proximal from the carpal tunnel. In the other cases the compression site extended over a longer trajectory. There were 37 different histological types of lesions. Complete resection of the tumor was possible in 58 cases. A total of 8 patients presented for the second time after receiving initial therapy. During follow-up, three cases of recurrence were reported with a mean follow-up period of 11 months. The most common published cause of median nerve compression is the lipofibromatous hamartoma. Besides the typical sensory and motor symptoms of median nerve compression, a thorough physical examination of the complete upper extremity is necessary to find any swelling or triggering that might raise suspicion of the presence of a tumor.
