Carpal Tunnel Syndrome in Patients Undergoing Long-Term Hemodialysis Therapy: Clinical Characteristics and Results of Surgical Treatment

PURPOSE: Carpal tunnel syndrome (CTS) has become increasingly recognized as a complication of long-term hemodialysis. This study evaluated the clinical characteristics and compared the results of carpal tunnel release for CTS patients with or without hemodialysis. METHODS: We retrospectively reviewed the clinical characteristics and surgical outcomes of 49 chronic hemodialysis patients with 83 CTS hands. Also, 100 patients were selected for the control group. Patient characteristics, accompanying systemic conditions, operative outcomes were compared. RESULTS: In hemodialysis group, the mean age and hemodialysis duration were 59.5+/-10.5 years and 4.1+/-2.5 years, respectively. Of the 83 hands with CTS, 45 (54.2%) had arteriovenous fistulas, while 38 (45.7%) did not (p=0.02). Most (81.6%) of the patients reported symptom improvement after surgical treatment, and the remaining patients (18.4%) reported persistent and recurrent symptoms. Rates of remaining symptoms and reoperations were significantly higher in the CTS patients with hemodialysis group. CONCLUSION: Majority of CTS patients with hemodialysis have much improved after transverse carpal ligament release. However, they showed higher recurrence than idiopathic CTS patients. In recurrent patients, use of the extended carpal tunnel release is effective in symptom relief.

Comparative Study of Electromyography and Hand Elevation Test in Carpal Tunnel Syndrome

PURPOSE: Since the hand elevation test was first introduced by Ahn in 2001, it has been one of most performing provocative test for diagnosing carpal tunnel syndrome. Although many studies have been published on the hand elevation test, there are no study that can explain why false-negative results of hand elevation test appears in carpal tunnel syndrome patients diagnosed by electromyography (EMG) findings. Therefore we searched out whether hand elevation test is related with EMG severity. MATERIALS AND METHODS: We made a retrospective study of 654 bilateral carpal tunnel syndrome patients. Among them 134 were studied which had different hand elevation test results on each hands. The paired samples t-test was used to compare the EMG severity of each group. The relationships between hand elevation test and EMG severity were examined using Pearson-product correlations. Comparing whether the frequency of false negative hand elevation were different between both hands, and whether the severity of EMG depends on which side of hand is, was evaluated with Mann-Whitney U-test. RESULTS: Severity of EMG in positive group was moderate to severe on average, whereas mild to moderate on negative group, with significant difference statistically (p<0.001). Correlation between the hand elevation test results and EMG severity also showed significance statistically (p<0.001). CONCLUSION: Mild severity of EMG was found out to be the factor affecting the false results. However, EMG severity and hand elevation test shows a meaningful correlation, supporting the value of hand elevation test.

Stabilizing Morbidity and Predicting the Aesthetic Results of Radial Forearm Free Flap Donor Sites

BACKGROUND: The radial forearm flap is a versatile, widely used flap. However, the possibility of donor site complications has led to concern over its use. Some surgeons prefer using other flaps whose donor sites can be closed primarily with less morbidity, including avoiding unpleasant scarring. However, in our experience, donor site stability of the radial forearm flap can be reliably achieved by using well-implemented specific procedures. Here, we present a collection of donor site cases of the radial forearm flap and investigate factors that affect the aesthetic results as the basis for a reference for selecting a radial forearm flap. METHODS: In this retrospective study, we reviewed 171 cases in which a radial forearm flap was used for free tissue transfer after resecting head and neck cancer. We focused on donor site morbidity rates. Each operation involved a detailed procedure designed to minimize donor site morbidity. Moreover, statistical investigations were conducted for 22 cases to determine factors affecting the scar appearance. RESULTS: Only one case developed total skin graft necrosis as a major complication. Scar-related aesthetic results were acceptable, and the body-mass index, body weight, diabetes, and cardiac problems were significant factors related to the appearance of scars. CONCLUSIONS: Performing the radial forearm flap using a well-implemented detailed technique helps achieve acceptable donor site morbidity results. The aesthetic results were more promising for patients without excess body weight, diabetes, or cardiac problems. Therefore, anxiety about donor site morbidity should not be a reason to avoid selecting the radial forearm flap in suitable patients.

Laparoscopic Repair of Traumatic Intraperitoneal Urinary Bladder Rupture / 대한비뇨기과학회지

The development, over the last 10 years, of laparoscopy has revitalized interest in the minimal invasive technique as a diagnostic tool in trauma cases. Laparoscopy is advocated to lessen the morbidity associated with open procedures. In trauma cases, therapeutic laparoscopy has not been advocated due to potential missed injury, but several authors have reported laparoscopic repairs of simple intra-abdominal injuries. We report a case of intraperitoneal bladder rupture treated with laparoscopy.

A Case of Idiopathic Calcinosis of the Scrotum / 대한비뇨기과학회지

The idiopathic calcinosis of the scrotum is multiple and asymptomatic nodules of scrotal skin which can onset either in childhood or early adulthood. It increases in size and number, while breakingdown to discharge chalky contents on occasions. We report a case of a 68-year-old-man who was effectively treated with a simple excision of the affected skin with an idiopathic scrotal calcinosis. There is no family history of scrotal calcification. Histopathologically, multiple nodules showed the epidermal cyst with partially degenerated wall and calcium deposits with a foreign body reaction in the dermis in this case. In most reported cases, some intact epidermal cysts are also present, and dystrophic calcification, and possible inflammation and rupture of epidermal cysts regarded as be the main pathogenetic mechanism of the disease.
