PURPOSE: Because cryptorchid testes are known to undergo histopathologic changes affecting development, maturation, and tertility, early surgical correction is usually recommended. However there are differing opinions concerning whether retractile testes are affected by similar changes and also whether there is a need for surgical treatment. We aimed to assess the histopathologic changes in retractile testis by studying the changes in testes artificially placed back in the abdomen after they have descended to scrotum in experimental rat models. MATERIALS AND METHODS: Male Sprague-Dawley rats were divided into 3 groups; a control group(controls), prepubertal ascent group (P) in which testis were placed back intraabdominally by bilateral inguinal canal obstruction at 6 weeks, a neonatal group(N) in which intraabdminal testis was induced by bilateral inguinal canal obstruction at birth. The relative weight of the testis, morphology of the seminiferous tubules including Leydig cells, tubular degeneration phase(TDP), spermatogonia per tubules(S/T), and Sertoli cell index (SCI) of these three groups were analyzed and compared. RESULTS: The relative weight of testis was significantly decreased in the group of N(0.0016+/-0.001) and P(0.0015+/-0.0002) compared to controls(0.0037+/-0.0002) (p<0.05). The S/T value was also decreased in P(2.05+/-18.2) and N(73.2+/-32.4) when compared to controls (360.2+/-21.3). Similar changes were observed in SCI of both P(64.5+/-6.4) and N (91.2+/-14.2) when compared to controls (227.9+/-31.1). Only minority of N and P showed higher TDP values. However, although statistically insignificant, TDP was increased in both P and N when compared to controls. The Leydig cells in N and P showed cellular distortion and hypertrophy. CONCLUSIONS: This study demonstrate that prepubertal ascent, similar to that of innate cryptorchid testis, also can induce histopathologic changes such as changes in testicular seminiferous tubule, decrease in the S/T value and decrease in SCI value. Our findings supports that hypothesis that retractile testis may cause histological damage thus surgical correction may also be warranted similar to in case of genuine cryptorchism.

BACKGROUND: The purpose of this study was to evaluate the applicability of the Korean version of Fall Efficacy scale(FES) and Activities-specific Balance Confidence Scale(ABC) to Korean older adult through an examination of instrument`s internal consistency and validity METHOD: A sample of 90 Korean older adults who lived in a community completed a survey instrument which included Korean version of FES and ABC. Because of comparable data derived from each scale, fear of falling and quality of life, activity daily living were included. Concurrent validity, criterion validity and correlational validity were tested. Reliability was tested by internal consistency, test-retest method. RESULTS: Cronbach`s alpha was 0.9043 in FES, and 0.99623 in ABC. Test-retest correlations in all scales were higher than 7.0. Statistically significant association was found between fear of falling and both scales. Correlation coefficient between Quality of life(SF-8) and ABC was -0.142(p=0.049). Both FES and ABC are correlated significantly each other. CONCLUSION: The Korean version of FES and ABC appears to be a reliable and valid method for meas- uring fear of falling. These instruments may be useful in assessing the independent contribution of fear of falling. ABC scale may be more useful to detect loss of balance confidence in more highly functioning seniors.

Since introduction of venous flap in 1980, many experimental studies and clinical applications of various kinds of venous flaps were reported. Venous flap has the following advantages : (1) nonbulky and goo-quality of flap (2) long & large vascular pedicle (3) easy & rapid elevation of flap (4) no sacrifice of major arteries (5) a single operative field. But, we also have some disadvantages of difficult handling of the pliable veins and the tmcertainty of flap survival. For the better result we had to design the size of the flap larger than that of defect and increase the number of draining vein to reduce the postoperative edema of the flap. We have treated the defects of soft tissue of the hand using free arterialized venous flap from the flexor aspect of the forearm & had an excellent results.

Chronic perineal pain is an often encountered problem, which produces a great degree of functional impairment and frustration to the patient and a challenge to the treating physician. The reason for this problem is that the region contains diverse anatomic structures with mixed somatic, visceral and autonomic innervations affecting bladder and bowel control and sexual function. A blockade of nociceptive and sympathetic supply to the perineal region, supplied through the ganglion impar has been shown to benefit patients with chronic perineal pain. Several options to this block have been described that chemical neurolysis, radiofrequency ablation etc. Although the analgesic effect of Botulinum toxin type A (BoNT-A) has long been considered secondary to its action for muscle relaxation, BoNT-A also affects the release of the neurotransmitters that are involved in pain perception. We describe a patient who was successfully given ganglion impar block with BoNT-A.

Because of the frequent misdiagnosis of the carpal injury, the orthopedic surgeon must know the mechanism of injury and exact radiological interpretation. We had encountered 114 cases of carpal injury, in which carpal fracture, carpal dislocation and instability were analysed by radiological examination. The following results were obtained: 1. In 75 carpal bone fractures, the most common fracture was scaphoid fracture (64 cases), the next com- mon one was triangular fracture (4 cases). 2. Among the 64 scaphoid fractures, the waist portion was the most frequent site (45 cases) and the least was tubercle fracture (2 cases). 3. Of the carpal bone fractures, the fresh fracture was 48 cases (64%) and old one was 27 cases (36%), these showed sclerosis, cystic change, and degenerative change in radiological examination. 4. In 14 carpal dislocations, perilunar dislocation was 2.5 times move common than lunate dislocation, and the trans-scaphoid perilunar dislocation was the most common dislocation. 5. Carpal instability was 25 cases. These were dorsiflexion instability, navicular rotary subluxation, and pal- mar-flexion instability. The most common instability was dorsiflexion instability.

A spinal epidural hemangioma is rare. In this case, a 51 year-old female patient had low back pain and right thigh numbness. She was initially misdiagnosed as having a ruptured disc with possible sequestration of granulation tissue formation due to the limited number of spinal epidural hemangiomas and little-known radiological findings. Because there are no effective diagnostic tools to verify the hemangioma, more effort should be put into preoperative imaging tests to avoid misdiagnosis and poor decisions).

BACKGROUND/AIMS: Nuclear factor-kappa B p65 (NF-kappa B p65), nuclear factor-kappa B1 p50 (NF-kappa B p50) have been shown to play a role in cell proliferation, apoptosis, cytokine production, and oncogenesis. Recently, p38 mitogen-activated protein kinase (MAPK)/ NF-kappa B/ cyclin D1 signaling pathway has been shown to play an important part in the pathogenesis of human cancers. This study was designed to investigate the expression of NF-kappa B p65, NF-kappa B p50, p38 MAPK alpha, and cyclin D1 proteins in premalignant lesions of colon and colorectal adenocarcinoma. METHODS: Paraffin sections of 20 normal mucosa, 20 low-grade tubular adenoma, 20 high-grade tubular adenoma and 64 adenocarcinoma tissues were analysed immunohistochemically for the expression of NF-kappa B p65, NF-kappa B p50, p38 MAPK alpha, and cyclin D1 proteins. RESULTS: The expression of NF-kappa B p65, NF-kappa B p50, and p38 MAPK alpha proteins were significantly higher in adenocarcinoma tissue in comparison with that in normal mucosa, low-grade tubular adenoma, and high-grade tubular adenoma tissues. Expression of NF-kappa B p50 was more frequent in poorly differentiated histologic grade, presence of nodal metastasis, and advanced stage. Expression of p38 MAPK alpha protein was higher in advanced tumor stage, presence of nodal metastasis and advanced stage. Synchronous expression of NF-kappa B p65, NF-kappa B p50, p38 MAPK alpha, and cyclin D1 proteins were significantly higher in adenocarcinoma tissue. CONCULSIONS: With the increased expression of NF-kappa B p65, NF-kappa B p50, and p38 MAPK alpha proteins, p38 MAPK/ NF-kappa B/ cyclin D1 signaling pathway may play a role in the pathogenesis of colorectal carcinoma.

PURPOSE: The purpose of this study was to evaluate the clinicopathological significance of the microvessel density and macrophage and mast cell counts in invasive breast carcinomas. MATERIALS AND METHODS: 45 invasive breast carcinomas were immunohistochemically stained with the endothelial antigen, CD34, and macrophage marker, CD68. 0.1% toluidine blue was used to highlight mast cells. The microvessel and mast cell counts were performed at x200 magnification and the macrophages at x400 magnification. RESULTS: With the 45 invasive breast carcinomas, there were no statistically significant associations between the mast cell, macrophage and microvessel counts and the tumor size and lymph node status. ER and PR negative mast cells infiltrated more than in cases of positive stati, with statistical significance (p-value=0.010 and 0.005, respectively). The macrophage counts were negatively correlated with the PR status (p-value=0.030). With respect to the c-erbB-2 status, there was no significance correlation with the mast cell, macrophage and microvessel counts. The mast cell counts showed significantly positive correlation with the microvessel counts in the invasive breast carcinomas (p-value=0.015). In a comparison of the macrophage counts with the microvessel counts, a positive tendency for both parameters, but without statistical significance (p-value=0.310). CONCLUSION: Increasing numbers of mast cells and macrophages were recruited in invasive breast carcinomas, which contribute to angiogenesis. The microvessel density in invasive breast carcinomas had no statistically significant association with the tumor size, lymph node status, and histological grade, presence of DCIS component, estrogen/progesterone receptor status and cerbB-2 status. The evaluation of angiogenesis using these methods is not thought to provide an independent clinicopathological factor in invasive breast carcinomas.

Tamoxifen and radiotherapy are used in breast cancer treatment worldwide. Radiation recall dermatitis (RRD), induced by tamoxifen, has been rarely reported. Herein, we report a RRD case induced by tamoxifen. A 47-year-old woman had a right quadrantectomy and an axillary lymph node dissection due to breast cancer. The tumor was staged pT2N0; it was hormone receptor positive, and human epidermal growth factor receptor 2 negative. The patient received adjuvant chemotherapy followed by tamoxifen and radiotherapy. After 22 months of tamoxifen, the patient developed a localized heating sensation, tenderness, edema, and redness at the irradiated area of the right breast. The symptoms improved within 1 week without treatment. Three weeks later, however, the patient developed similar symptoms in the same area of the breast. She continued tamoxifen before and during dermatitis, and symptoms resolved within 1 week.

PURPOSE: Patients with neurogenic bladder ultimately undergo morphometric and functional changes of their bladder and urethra. As a result, voiding symptoms such as frequency, nocturia, urgency and incontinence appear Propiverine hydrochloride(BUP-4) is a benzylic acid derivative with musculotropic antispamodic activity and moderate anticholinergic effect. We evaluated the clinical and urodynamic effects of BUP-4 for patients with neurogenic urinary frequency and incontinence MATERIALS AND METHODS: Twenty six patients with neurogenic bladder suffering from urinary frequency and incontinence(including 5 placebo) were given 20mg of BUP-4 orally a day and its clinical and urodynamic effect were evaluated. RESULTS: In the group treated with BUP-4 for four weeks, 57.9% in 19 patients with frequency, 53.3% in 15 nocturia, 50.0% in 14 weak stream, 55.6% in 9 intermittency, 50.0% in 10 dribbling, 64.3% in 14 urgency, 55.6% in 9 hesitancy, 73.7% in 19 incontinence showed improvement of their symptom. Urodynamic study performed after treatment with BUP-4 for 4 weeks or more revealed greater than 10% increase in bladder capacity compared to pretreatment study in 11 patients out of 21(52.4%) and their maximum bladder capacity increased significantly from 181.7+/-101.3 to 249.4+/- 184.7mL(p=0.012). Maximum detrusor pressure decreased from 52.5+/-35.6 to 50.9+/- 26.8cmH2O(p=0.010). Changes in compliance and volume on the first urge sense were statistically insignificant. In placebo group, no significant symptomatic and urodynamic improvement were reported. Side effects of the drug had appeared in 7 patients(33.3%) out of 21 after 4 weeks of treatment -5 cases of dry mouth and 2 cases of nausea - but they were not severe enough to stop the treatment. CONCLUSIONS: The use of BUP-4 in patients with neurogenic bladder results in improvement of symptoms and urodynamic profile(bladder capacity and maximum detrusor pressure). Thus, BUP-4 could be used as one of the first line drugs in the treatment of patients with neurogenic bladder.
