In our series with old electrical burn around the the wrist, there are several characteristics: for example, bad scarring in palm and volar aspect of wrist and distal forearm, large multiple defects of the flexor tendons, low median and ulnar nerve palsy, and occasionally insufficient blood supply. Between 1992 and 1995, we treated 8 cases of 7 patients with staged reconstruction. 4 patients with bilateral involvements had below-elbow amputee of contralateral upper extremity. The common approachs in each were soft tissue coverage, staged tendon reconstructiuon, and opponensplasty. The length of time between the injury and tendon reconstruction was 9 months on an average. Soft tissue coverage consisted of: 1. free tissue transfer (n=3), 2. abdominal (n=3) or groin (n=2). Total numbers of flexor tendon reconstruction were 26. Among them, staged reconstruction using silicone prosthesis were done in 18 tendons and primary tendon graft following tenolysis were done in 8 tendons. The time between first and second stage tendon reconstruction was 4.13 months. In all cases, opponen-splasty using extensor indicis proprius (n=4), extensor pollicis longus (n=2), and extensor digiti mini- mi (n=l), were performed. Good functional improvement of the hand were obtained in all cases. Patient s satisfaction were much better than the degree of functional improvement of the hand.

Vascularized fibular graft is one of the treatment option for avascular necrosis of femoral head (ANFH) and has been known as providing a strut mechanical support and new vascular bed. It is very important to evaluate a healing process in femoral head after vascularization procedure. But a plain radiographic finding has a problem to assess pathological changes of ANFH treated with vascularized fibular graft. Authors analyzed chronogical changes of Tc-99m-HDP bone scan in 31 cases of ANFH treated with vascularized fibular graft from April, 1991 to May, 1994 and following results were obtained. l. Until 2 months after surgery, no change in size of cold defect area and no significant change in extent of RI uptake in reactive zone were noted. 2. During 2 months and 6 months after surgery, slight decrease in size of cold defect area and minimal changes in extent of RI uptake in reactive zone were observed. 3. During 6 months and 12 months after surgery, size of cold defect area decreased to 1/2 and changes in extent and degree of RI uptake in reactive zone were observed. 4. During 1 year and 2 years after surgery, size of cold defect area were minimal and sometimes faded away. RI uptake with decreased density in reactive zone broadened and moved to subchondral area. 5. After 2 years after surgery, cold area faded away and small increased RI uptake were observed in same site. In conclusion, Tc-99m-HDP bone scan which is economic and easily applicable in a patient is very useful for follow up study in ANFH treated with vascularized fibular graft.

OBJECTIVES: The purpose of this study is investigate the clinical characteristics and the change of depression and anxiety in pathological gamblers who completed 10-week admission treatment programs. METHODS: To investigate the clinical characteristics, we included 40 pathological gamblers who completed admission treatment programs from Jan 2006 to Jun 2010. To measure the change through treatment, we included 16 patients who completed pre-treatment and post-treatment assessment scales, including the Korean-National Opinion Research Center DSM-IV Screen for Gambling Problems (K-NODS), Beck's Depression Inventory (BDI), and the State-trait Anxiety Inventory (STAI), from May 2008 to Aug 2008. RESULTS: Mean age of the patients was 42.9+/-9.0 years and mean intelligent quotient was 109.7+/-10.4. Thirty (75%) patients showed comorbid disorders, including depression (14 patients, 35%), anxiety disorder (five patients, 12.5%), alcohol use disorder (five patients, 12.5%), and personality disorder (four patients, 10%). After treatment, K-NODS, BDI, STAI-I, and STAI-II scores showed improvement, from 9.1+/-1.5 to 7.6+/-2.7, from 23.5+/-5.8 to 11.1+/-3.2, from 52.6+/-10.3 to 41.9+/-7.1, and from 53.7+/-10.6 to 46.0+/-4.4, respectively. CONCLUSION: In treatment of pathological gambling, comorbid psychiatric risk factors, such as depression and anxiety should be considered.

OBJECTIVE: The purpose of this study was to evaluate the accuracy of a preoperative MRI with microscopy coils in determining the primary tumor thickness of malignant melanoma with histopathologic correlation. MATERIALS AND METHODS: Eleven patients with histopathologically confirmed malignant melanoma were included in this study. MR images of the tumors were obtained with a 47-mm microscopy coil on 1.5T MR scanners and were evaluated by two radiologists, who assessed the thickness of the primary tumor on T2-weighted images (T2WI) and gadolinium-enhanced T1-weighted images with fat suppression (Gd-T1WI) and compared the results with the histopathologic findings as the reference standard. Correlations between tumor thickness on MRI and histopathologic examination were assessed using concordance correlation coefficients (CCCs). Inter- and intraobserver variabilities of tumor measurements were also assessed by intraclass correlation coefficient (ICC). RESULTS: Among the 11 cases included in the study, 10 cases from the same number of patients were managed with surgical excision and one case was confirmed with punch biopsy. The primary tumor thickness measured on T2WI showed better correlation with histopathologic results, as compared with measurements taken on Gd-T1WI: the CCC of measurements on T2WI ranged from 0.64 to 0.78, indicating a substantial agreement, whereas the CCC of measurements on Gd-T1WI ranged from 0.50 to 0.61, indicating a moderate to substantial agreement. Inter- and intraobserver agreements of readers 1 and 2 were excellent for both T2WI and Gd-T1WI, with ICC ranging from 0.86 to 0.99. CONCLUSION: MR imaging with microscopy coils may be an accurate technique in the preoperative assessment of tumor thickness in malignant melanoma, especially on T2-weighted images.

Interleukin-6 (IL-6) and its receptor are presumed to play important roles in the developing nervous system. However, little is known about their potential role(s) in the developing kidney. To investigate this, we have studied the expression of IL-6 and its receptor (IL-6R) in the developing rat kidney. Kidneys from 16- (F16), 18- and 20-day-old (F20) fetuses, 1- (P1), 3- (P3), 7- (P7) and 14-day-old (P14) pups, and adult rats were extracted. Renal expressions of IL-6 and its receptors were examined by immunohistochemistry and in situ hybridization respectively. Il-6 protein already appeared in F16. The early stage of renal development before birth, IL-6 showed strong immunoreactivity in the ureteric bud, metanephric mesenchymal cells (MMC) and developing glomerulus. The expression pattern of IL-6 in nephrogenic zone are very similar even after birth. In matured nephron after birth, IL-6 immunoreactivities were detected in distal tubules strongly, and collecting ducts moderately and thick ascending limb weekly. IL-6R hybridization signals have also already appeared in 16-day old fetal kidney. Before birth, IL-6R mRNAs were expressed in ureteric bud, MMC and developing glomerulus. In the matured nephron after birth, IL-6R mRNA was expressed in the thick ascending limb, distal tubules, collecting ducts and S3 segment of proximal tubule. These results suggest that IL-6 and its receptor may be involved in regulation of nephron formation in nephrogenic zone of rat, and play a role in distal nephron including collecting duct after birth.

Neurilemmoma, like other non-epithelial tumors, seldom occurs in the thyroid gland. We present a case of a 61-year-old woman with a neurilemmoma of her left thyroid lobe. She was clinically and biochemically euthyroid, and underwent a left thyroid lobectomy without complications. The tumor was an encapsulated solid mass, 34x23x1 5mm in size and was diagnosed as neurilemmoma. Neurilemmoma of the thyroid gland tends to develop in the right lobe, but this case was in the left.
