Morphological studies have an important role in establishing the timing of irreversible damage occurred in cryptorchid testis. The present study was undertaken to determine how soon definitive sign or testis pathology may appear in cyptorchid testis. Testicular biopsies were collected at the time of orchiopexy from 79 patients during the period from January, 1988 to June, 1990, and then we examined ultrastructural changes of cryptorchid testis with light and electron microscopy. Comparing with normal testis, following results were obtained ; l. The volume of cryptorchid testis became smaller than normal after age of 14. 2. Mean tubular diameter became smaller after age of 14 and basement membrane thickened prominently after age of 20. 3. The increase number of mitochondria appeared at age of 2 4. Cytoplasmic vacuolization became prominent after age of 6, but detachment and loss of ribosome appeared at age of 20. 5. Tunica propria showed marked thickening and collagenous degeneration after age of 14. With above results, we suggest that orchiopexy should be done before age of 2.

Emphysematous pyelonephritis is a rare, life endangering suppurative infection characterized by the production of intrarenal and occasionally perirenal gas which generally occurs in patient with diabetes mellitus or urinary tract obstruction. Clinically, it appears as an acute severe clinical pyelonephritis that needs emergency care with poor prognosis. Recently, we experienced six cases of emphysematous pyelonephritis, so a clinical study was made on these six patients who were admitted to the Department of Urology, Kyung Hee University from April 1986 to June 1987. The results were as followings : 1. Four patients were female and 2 were male, age distribution ranged from 31 to 72 years. All patients had diabetes mellitus and duration of diabetes mellitus ranged from 8 months to 10 years. 2. Causative organism were E. coli in 5 patients, and Mucormycosis in 1 patient who had alcoholism and septic pneumonia. 3. the disease involved right kidney in 3 patients, the left kidney in 3 patients. Bilateral emphysematous pyelonephritis was not found. 4. Simple abdominal radiography and renal sonogram were performed in 6 patients to identify the gas in renal area. Computerized tomography were used to localize the gas and extent of infection, in 4 patients. Intraparenchymal gas only was found in 1 patient, gas in renal parenchyme and perineral space was found in 5 patients. 5 3 patients were treated by conservative management and other 3 patients underwent nephrectomy. 2 patients were expired, one is treated by nephrectomy and another by conservative ma-nagement each other. 4 patients survived.

Torsion of the testis is a common urological emergency. We treated 28 cases of spermatic cord torsion during the period from March. 1978 to November, 1988. Detorsion with orchiopexy was performed in 19 cases, remaining cases underwent orchiectomy. Follow up was made in 13 cases who underwent detorsion with orchiopexy, and 11 cases of them under went testicular biopsy at same operation field. histopathologic findings of testicular biopsies were compared with clinical characteristics and courses of patients. The results were as follows : 1. Among the group of biopsy, testicular atrophy occurred in 5 cases and normal testis was palpable in 6 cases 2. Testicular salvage is closely related with duration of symptoms. 3. Histopathologic findings of atrophic testis group showed marked hemorrhagic necrosis of seminiferous tubule and interstitial tissue, but normally palpable testis group showed mild to moderate congestive and hemorrhagic changes of seminiferous tubule and interstitial tissue. 4. histopathologic changes were more deteriorative in the group of patients more delayed managed. 5. We could predict fate of testis after orchiopexy by biopsy findings.

Subcutaneous tissue calcification in rheumatic diseases usually occurs in connective tissue diseases, such as systemic lupus erythematosus, scleroderma, and dermatomyositis. Domestic cases of calcification in rheumatoid arthritis have not been reported. The mechanism of subcutaneous tissue calcification may differ depending on the cause and it can develop on all parts of the body. Calcification occurring in rheumatic diseases is a major mechanism of tissue damage caused by chronic inflammation. No standard therapy for calcification has been established; however, many studies have reported on medical and surgical treatment. We report on subcutaneous tissue calcification in a rheumatoid arthritis patient tissue calcification on both sides of the buttocks, the upper limbs, and the lower limbs.

Congenital mesoblastic nephroma is a slow-growing tumor considered to originate from renal mesenchyme and usually discovered before the age of 6 months. The tumor is almost invariably benign but has been mistaken for Wilms` tumor and unnecessarily overtreated. We report a case of congenital mesoblastic nephroma in 2 months aged infant.

BACKGROUND/AIMS: Hood cap-assisted chromocolonoscopy using indigocarmine is expected to improve the detection rate of colorectal polyps, especially adenomatous polyps. Therefore, aim of the present study was to evaluate the usefulness of hood cap-assisted chromocolonoscopy in routine colonoscopic examinations. METHODS: From January, 2013 through March, 2013, a total of 86 patients were enrolled (M:F=33:53, mean age=60 years). For each patient, hood cap-assisted colonoscopic examination was performed, followed by hood cap-assisted chromocolonoscopy using 0.2% indigocarmine from the cecum to the hepatic flexure. Total numbers and characteristics of polyps were compared before and after indigo carmine dye spraying. RESULTS: Prior to dye spraying, 48 polyps were found in 37 patients, and after dye spraying, 53 additional polyps were found in 34 patients. Of these undetected polyps, 45 (85%) were small sized polyps (< or =0.5 cm). Histologically, 19 (36%) were adenomatous polyps, and of these, 15 (28%) were tubular adenomas and 4 (8%) were serrated adenomas. As for the polyp detection rate, there was no difference between the expert and the non-expert groups. CONCLUSION: Hood cap-assisted chromocolonoscopic examination using indigocarmine was helpful in detecting cecum and ascending colon polyps, especially small sized polyps (<0.5 cm) and neoplastic polyps.

We report here a case of oral myiasis in the Republic of Korea. The patient was a 37-year-old man with a 30-year history of Becker's muscular dystrophy. He was intubated due to dyspnea 8 days prior to admission to an intensive care unit (ICU). A few hours after the ICU admission, 43 fly larvae were found during suction of the oral cavity. All maggots were identified as the third instars of Lucilia sericata (Diptera: Calliphoridae) by morphology. We discussed on the characteristics of myiasis acquired in Korea, including the infection risk and predisposing factors.

The Korean Endocrine Society (KES) published clinical practice guidelines for the treatment of acromegaly in 2011. Since then, the number of acromegaly cases, publications on studies addressing medical treatment of acromegaly, and demands for improvements in insurance coverage have been dramatically increasing. In 2017, the KES Committee of Health Insurance decided to publish a position statement regarding the use of somatostatin analogues in acromegaly. Accordingly, consensus opinions for the position statement were collected after intensive review of the relevant literature and discussions among experts affiliated with the KES, and the Korean Neuroendocrine Study Group. This position statement includes the characteristics, indications, dose, interval (including extended dose interval in case of lanreotide autogel), switching and preoperative use of somatostatin analogues in medical treatment of acromegaly. The recommended approach is based on the expert opinions in case of insufficient clinical evidence, and where discrepancies among the expert opinions were found, the experts voted to determine the recommended approach.

Acromegaly is a chronic disorder caused by excessive growth hormone (GH) secretion. In most cases, the excess GH originates from GH-producing pituitary adenomas. Surgery is the preferred first-line treatment for patients with acromegaly, but medical management is considered when the disease persists after surgery or in cases where patients refuse surgery or are poor candidates for surgery. Somatostatin analogues are commonly used to treat acromegaly. The Korean Endocrine Society and the Korean Neuroendocrine Study Group have developed a position statement for the use of somatostatin analogues in the medical treatment of acromegaly. This position statement is based on evidence from the current literature and expert opinions. In the case of discrepancies among expert opinions, the experts voted to determine the recommended approach.
