BACKGROUND: Although exact mechanism of adult respiratory distress syndorme (ARDS) is not known, many evidences suggest that inflammatory mediators such as protease and oxygen radicals may be the final common pathway to the endothelial injury. It is gradually accepted that activated neutrophils play a major role in the process. Pentoxifylline is a methylated xanthine with a wide range of actions that make it theoretically useful in the treatment of ARDS. Studies show that it decreases neutrophil phagocytosis and superoxied production. The aim of this experiment is to determine whether pentoxifylline has a preventive effect on oleic acid-induced lung injury. METHODS: Oleic acid (0.08 ml/kg) was infused in 10 mongrel dogs in order to induce acute lung injury. Pentoxifylline (20 mg/kg) was administered 40 mins before oleic acid injection. The author made a comparative studies on the effects of pentoxifylline on hemodynamics and gas exchange before oleic acid injection and at 15, 30, 45, 60, 90 mins after oleic acid injection. RESULTS: There were not significant changes in mean arterial pressure, cardiac output, systemic vascular resistence, pulmonary wedge pressure intrapulmonary shunt in both groups. There were statistical significance in arterial oxygen tension, pulmonary artery pressure, pulmonary vascular resistance between both groups (p<0.05). CONCLUSIONS: Pentoxifylline is a noteworthy drug that could be a candidate as a therapy to help prevent effect in lung injuries that share a common mechanism with oleic acid-induced lung injury.

Fracuture-dislocation of the cuboid is an extremely rere injury compared with fracture-dislocation of other tarsal bones. We report a case of the fracture-dislocation of the cuboid treated by open reduction and internal fixation.

One hundred and two patients with benign prostatic hyperplasia were treated by transurethral radio-frequency thermotherapy (TURT) device (Thermex-II, Direx, Israel) with 47.5 degrees C in single session for 2 hours and 30 minutes from November 1992 to October 1993. Among them, 83 patients, who were followed up for more than 3 months were included in this study. Twenty-seven (32.5%) patients had a history of acute retention. Pretreated values of the mean Madsen-Iversen symptom score, maximum urine flow rate, postvoiding residual urine volume, prostate volume and prostate specific antigen (PSA) were 15.4, 6.5 ml/sec, 61.3ml, 43.2ml and 0.77 ng/ml respectively. Madsen-Iversen symptom score, maximum urine flow rate were measured at 2 weeks, 1, 3 and 6 months after TURT. The residual urine volume, prostate volume and PSA level were measured at 3 and 6 months after TURT. During the follow up, the symptom score started to decrease significantly at 1 month (9.9, p< 0.01) after TURT, and gradually decreased up to 6.9 at 3 months. The maximum flow rate showed initial significant improvement at 2 weeks (8.1 ml/sec., p< 0.01), but no significant interval change was observed thereafter. The residual volume decreased significantly at 3 months (41.3 ml, p< 0.01) and no decrement was noted until 6 months. Neither the prostate volume nor PSA value changed significantly at 3 or 6 months after TURT. The improvement, which was defined as a change of 50% or more in at least one of subjective or objective symptoms showed in 63.9% (53/83) at 3 months and 57.1% (32/56) at 6 months. Both subjective and objective improvements at 3 and 6 months after treatment showed in 24.1% and 19.6%, respectively.

A clinical observation was made on 284 cases of renal diseases, admitted to the Department of Urology, National Medical Center from January 1972 to December 1971 The results were as follows ; 1) During this period, the total number of in-patients were 969 among which patients with renal diseases were 284 (29.3 %). And ratio between male and female patients was 1.2:1 2) Among renal diseases, the patients with tbc or stone were occupied over half (62.6 %). 3) In renal tbc, the prevalence rate of complication became decreased due to early treatment by early visiting to hospital. And patients taken with only anti-Tb medication became increased. 4) In renal stone or renal injury, there was tendency of taking conservative treatment(pyelolithotomy etc.) rather than taking surgical intervention as like nephrectomy etc.

6.Congenital hand differences: a comprehensive literature review

Upper extremity anomalies are the second most common type of congenital malformations. Approximately 1% to 3% of newborns are born with congenital anomalies, and among them, roughly 10% have upper extremity anomalies. Congenital hand anomalies are often isolated phenomena but may also coexist with other congenital anomalies or syndromes. These anomalies cause not only aesthetic concerns, but also significant functional deficits and psychological issues for children and their families. Surgeons should conduct a thorough examination to make an accurate diagnosis and provide appropriate treatment or refer the patient to a specialized clinic if necessary. Operative procedures should aim to restore both function and aesthetics. This article reviews the embryology of the hand, the classification of congenital hand anomalies, and the clinical features and treatment of common major congenital hand anomalies.

PURPOSE: Methylphenidate is the most widely used central nervous system stimulant in patients with attention deficit hyperactivity disorder. However, few studies have assessed its effects on voiding. Various doses of methylphenidate were investigated for their effects on cystometric parameters in conscious mice. METHODS: Ten male C57BL/6 mice, weighing between 20 and 23 g, were used in this study. To compare the acute drug responses before and after the oral medication was administered in the awake condition, we injected the solution through a catheter inserted into the stomach. Methylphenidate (1.25, 2.5, and 5 mg/kg) in an injection volume of 0.05 mL was administered. RESULTS: Four mice that received high doses of methylphenidate (2.5 and 5 mg/kg) showed no voiding contraction, with urine leakage. Six mice that received a low dose of methylphenidate (1.25 mg/kg) showed typical micturition cycles before and after administration. The micturition pressure decreased and bladder capacity increased without an increased residual volume after administration. CONCLUSIONS: Methylphenidate has differential, dose-dependent effects on the function of the lower urinary tract, due to the dependent relationship between the brain and lower urinary tract. Especially at higher doses, this drug may interfere with normal micturition. Therefore, more detailed clinical or experimental studies are warranted in the future.

The lumbar intraspinal epidural ganglion cyst has been a rare cause of the low back pain or leg pain. Ganglion cysts and synovial cysts compose the juxtafacet cysts. Extensive studies have been performed about the synovial cysts, however, very little has been known about the ganglion cyst. Current report is about two ganglion cysts associated with implicative findings in young male patients. We discuss about the underlying pathology of the ganglion cyst based on intraoperative evidences, associated disc herniation at the same location or severe degeneration of the ligament flavum that the cyst originated from in young patients.

Chylothorax is an accumulation of lymphatic fluid or chyle in the pleurual cavity resulting from a leak of the thoracic duct or one of its major divisions. If the loss of chyle persist, life threatening nutritional and immunologic deficiencies ensue. Initial conservative managements consist of tube thoracostomy drainage and dietary modification(low fat diet and total parenteral nutrition). In some refarctory cases, surgical intervention is required. Pleuroperitoneal shunt is an alternative surgical method recommended prior to thoracic duct ligation. The shunted fluid in the peritoneal cavity is reabsorbed by peritoenal lymphatic vessels running to join the right lymphatic duct. We experienced a case of chylothorax in a two-month-old female infant. Because there was no underlying disease to cause chylothorax, the diagnosis of idiopathic chylothorax was made. She failed to respond to conservative management and showed severe hypoalbuminemia and lymphopenia. On day 22, a pleuroperitoneal shunt was inserted between the right pleural cavity and the peritoneal cavity. Three weeks after insertion of the shunt, there was no fluid in the right pleural space. After one more week of observation, the shunt was removed.
