Cutaneous smooth muscle hamartomas are benign proliferations of smooth muscle bundles within the dermis. They can be congenital or acquired, and most cases are congenital. Congenital smooth muscle hamartomas (CSMHs) usually manifest at birth as well-circumscribed, frequently hypertrichotic, hyperpigmented or skin-colored patches or plaques on trunk or extremities. We report a case of CSMH in a 10 year-old girl, who showed a localized skin-colored patch showing prominent follicular papules on the lateral aspect of her right upper arm, which were found at birth. There was no hypertrichosis and the pseudo-Darier sign was negative. This patchy follicular variant is the less common clinical type of the disease.

Clostridium perfringens is an anaerobe responsible for a wide range of diseases in animals and humans. Symptoms associated with C. perfringens food poisoning are caused by enterotoxin expressed only during sporulation of C. perfringens. It has been known that only 6% of global C. perfringens isolates carry the enterotoxin gene. We found 2 strains of enterotoxigenic C. perfringens out of 33 strains isolated from various sources in Korea using PCR. It was also found that these two strains were both type A that were strongly associated with food poisoning by checking the presence of four major lethal toxins (a-, B-, e-, l-toxin) using PCR. These results suggest that foodborne illness caused by C. perfringens may be common in Korea and that public education is necessary to prevent contamination of foods by this organism.

Korean Journal of Urology 1998;39(6):585-588
PURPOSE: Metastatic prostatic adenocarcinoma can be controlled by androgen ablation through the active process of programmed cell death in androgen responsive cells. However, about 20-30% of patients have no clinical response to androgen withdrawal. Because of the importance of apoptosis in effecting tumor control, factors involved in this process may be helpful in predicting androgen insensitivity. So, we evaluated the significance of bcl-2 protooncogene expression pattern with therapeutic response of prostatic cancer MATERIALS AND METHODS: We examined the cellular expression of bel-2 protein using immunohistochemical stain in tumor samples from 40 patients with metastatic prostatic cancer(stage D) and determined whether expression of blc-2 protein has related to the therapeutic response of prostatic cancer. RESULTS: The hormonal status of the patient's tumor was determined by the clinical response to therapy. Androgen independent cancer was defined as that subset of patients who experienced no initial response to androgen ablation, or who experienced disease relapse following an initial response to androgen ablation. So, we found that androgen dependent prostatic cancer was 22 patients and androgen independent prostatic cancer was 18 patients. The positive staining for bcl-2 was 27.3%(6/22) and 83.3%(15/18) in androgen dependent and independent prostatic cancer, respectively. It was significant difference(p<0.05). CONCLUSIONS: These results suggest that bcl-2 expression is associated with androgen independent prostatic cancer and used one of the factors to predict which patient with prostatic cancer will respond to androgen ablation.

BACKGROUND: The aim of this study was to analyze the questions in the shoulder and elbow section of the Korean Orthopaedic In-Training Examination (KOITE) and compare them with those of the US Orthopaedic In-Training Examination (US OITE). METHODS: Twenty-nine questions in the shoulder and elbow section of the KOITE from 2010 to 2014 were analyzed and compared with those of the US OITE (80 questions) by literature review. A thorough analysis of the contents was performed after categorizing as topics, diagnostic tools, treatment modalities, taxonomic classification, and references. RESULTS: The shoulder and elbow section of the KOITE was 5.8% weight which was similar to the US OITE (5.9%). The most commonly appearing topic was anterior labral injury (17.2%) on the KOITE compared to instability and arthritis (21.3%, each) on the US OITE. Magnetic resonance imaging was most frequently appeared imaging modality on the KOITE (41.0%) compared to the radiograph on the US OITE (43.0%). The Latarjet procedure was the most commonly asked treatment modality (22.2%) on the KOITE, whereas arthroplasty (33.3%) on the US OITE. The KOITE showed an even taxonomic classification distribution compared to the US OITE. Campbell's operative orthopaedics covered 96.6% questions as a reference on the KOITE compared to the Journal of Bone and Joint Surgery, American Volume on the US OITE, which covered 45.0%. CONCLUSIONS: This specific analysis shows us current trends of the shoulder and elbow section of the KOITE and it might be developed for use in the educational curricula for the trainee.

Ovaries lie near the distal ureter where extracorporeal shock wave lithotripsy (ESWL) of calculi is performed. The question whether ESWL may induce morphological changes in ovary should be investigated in animal experiments. After applying shock waves to ovary of Sprague Dawley female rat, the histopathologic changes within the tissue of ovary were observed immediately after shock waves and after recovery. For animal subjects, 25 healthy rats weighing about 250 grams each were used. Five rats were designated as control, and remaining 20 received shock waves at 20 kV for 1,000 times using Pendulum-ESWL (Lithoring), a third generation lithotriptor. The 20 rats were divided into 4 groups before shock waves, and each group was sacrificed after 1, 7, 14, and 28 days, respectively, in order to compare the observed histopathologic changes. Edema, congestion and hemorrhage were observed in ovary after 1 and 7 days of shock waves, but the edema and congestion were significantly reduced on the 14th day and completely disappeared on the 28th day. There was no ovarian follicular changes or fibrosis on the whole. It is thought that the extracorporeal shock waves have no specific effects on the tissues of ovary, but further studies ate needed to determine its long term effects.

Purulent pericarditis is an infrequent but fulminant and frequently lethal disease. Purulent pericarditis tends to occur as direct extension of bacterial pneumonia or empyema in past. In recently, purulent pericarditis tends to occur in adult via contiguous spread from an early postoperative infection after thoracic surgery or trauma, infection related to infective endocarditis, extension from a subdiaphragmatic suppurative source, and hematogenous spread during bacteremia. Endogenous causes of purulent pericarditis are frequently characterized as esophageal perforations. Common causes of esophageal perforations related to purulent pericaditis which usually develop in association with mediastinitis, pneumonia and empyema include corrosive esophagitis, complication after esophageal and tracheal instrumentation and Boerhaave's syndrome. There is very little reference to the development of pericarditis in associated with esophageal perforation which does not directly communicate with the pericardium. while, although most uncommon, it is well documented that the esophagus can perforate directly into the pericardium and produce pericarditis. We experienced a case of acute purulent pericarditis after esophageal and pericardial perforation by a small fish bone in a previously healthy man. The patient was treated successfully with systemic antibiotics and pericardiotomy.

PURPOSE: The objective of this study was to evaluate an immunoassay for urinary nuclear matrix protein (NMP22) as an indicator for transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Three groups of subjects attended the trial of NMP22. First group was 27 patients with transitional cell carcinoma of the bladder, second group was 24 patients with other urinary cancer consisted of prostate cancer and renal cell carcinoma, and third group was 24 healthy volunteers. NMP22 was determined using a commercial test kit, which is based on an enzyme-linked immunosorbent assay. RESULTS: In normal healthy volunteers and other urinary cancer group median NMP22 levels were 2.24 and 3.27 U/ml, respectively. Median urinary NMP22 levels in patients with transitional cell carcinoma of the bladder were 54.30 U/ml. It was significantly greater than other two groups. Median NMP22 levels according to the tumor stage and the tumor grade did not show the significant difference statistically. CONCLUSIONS: Urinary NMP22 is a useful marker that is more specific for bladder cancer thsn for other urinary cancer. Further tests are required to clarify the influence of other spe- cific conditions, such as urinary tract infection, and intravesical drug instillation or procedure.

PURPOSE: The role of growth hormone in the tumor-bearing host is controversial because of its potential to stimulate tumor growth. So, this study was done to determine the effects of growth hormone on primary tumor growth and body weight change in tumor-bearing animals receiving either high protein or protein-depleted diet. MATERIALS AND METHODS: Tumors were induced in nude mice by subcutaneous injection of 1x106/ml PC-3 cells. Nude mice were fed with high protein diet at the time of tumor cell injection. Six weeks later, after measurable tumors were formed, the animals were randomized to receive either high protein diet(20.0% protein) or protein-depleted diet(0.04% protein). Animals in each dietary group were randomized to receive daily subcutaneous injections of either growth hormone(1,000 mU/kg) or placebo(normal saline) for 2 weeks. After then, animals were sacrificed by carbon dioxide inhalation, and, subsequently body weight and tumor volume were measured. RESULTS: At the end of the experiment, the body weights of group I(protein depleted diet+ormal saline) and II(protein depleted diet+growth hormone) were checked at 22.6+/-1.9 g and 24.9+/-1.6 g, respectively. But the body weights of group III(high protein diet+normal saline) and IV(high protein diet+growth hormone) increased to 32.5+/-1.2 g and 36.9+/-1.5 g, respectively. So in high protein diet group, body weight increases were observed and, in group which also had subcutaneous injections of growth hormone, the increases were more prominent. At the end of experiment, the tumor volumes of group I, II, III, and IV were checked at 0.88+/-0.02 cm3, 0.89+/-0.03 cm3, 1.31+/-0.02 cm3, and 1.30+/-0.02 cm3, respectively. So high protein diet group demonstrated large tumor volume increases, but there were no significant differences compared with group that also had subcutaneous injections of growth hormone, which implies growth hormone itself didn`t have large effect on tumor volume change. And, the ratios of tumor volume to body weight assessed at the end of experiment proved to be 3.94+/-0.33 %, 3.60+/-0.26 %, 3.89+/-0.08 %, and 3.54+/-0.18 % for group I, II, III, and IV, respectively which is showing no significant differences among them. CONCLUSIONS: These results suggest that the growth hormone dose not accelerate the growth of tumor volume in nude mice bearing prostatic cancer. Thus simultaneous treatment of growth hormone and high protein diet may improve the performance status without accelerating the growth of tumor volume in patients with advanced prostatic cancer.
