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.

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.

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.

PURPOSE: Non-preaxial polydactyly of the hand refers to axial polysyndactyly involving the 2nd, 3rd, or 4th finger and postaxial polydactyly involving the 5th finger. It has a much lower incidence and a higher genetic penetrance than preaxial type. METHODS: Medical records of the patients who had operation for their polydactyly between July 1997 and July 2015 were retrospectively reviewed. The clinical data of the patients were investigated regarding demographics, clinical findings of the involved digits, foot involvement, and genetic penetrance. Through postoperative follow-up based on physical and radiologic examinations, we assessed functional and aesthetic outcomes, postoperative complications, and reoperation rate. RESULTS: Twenty-four patients (17 males and 7 females) underwent surgery for non-preaxial polydactyly of the hand. There were 15 postaxial type polydactyly, and 9 axial type polysyndactyly. Thirteen patients had bilateral involvement (54.2%), while 5 patients (20.8%) were right-sided and 6 patients (25%) were left-sided. In the axial type, 4th finger was the most frequently involved in 8 patients, followed by the 3rd finger in 1 patient. Thirteen patients (54.2%) had concurrent congenital foot anomalies. One patient (4.2%) had a family history of congenital hand anomaly. Patients with axial type polysyndactyly had poorer postoperative outcome than those with postaxial type, regarding reoperation rate. CONCLUSION: Non-preaxial polydactyly is a very rare congenital hand anomaly and the surgical outcome is not always promising especially in the axial type. Therefore, it is necessary to provide a sufficient preoperative counseling and to perform a meticulous surgery.

PURPOSE: We investigated the clinical characteristics and relationship between chromosome and its phenotypic expression in patients with 45 XO/46XY mosaicism or 45 XO with SRY gene. MATERIALS AND METHODS: 11 patients with 45XO/46XY chromosomal abnormality and 4 patients with 45XO with SRY positive reaction admitted from 1990 to 1996 were evaluated. Patients were grouped according to chromosome and gonadal expression. Group A consisted of patients with 45XO/46XY chromosome and unilateral streak gonad, group B patients with 45XO chromosome, SRY positive reaction and unilateral streak gonad and group C patients with 45XO/46XY chromosome and bilateral streak gonads. RESULTS: Of the total 15 patients, the number of patients in group A, B, and C were 8, 4, and 3, respectively. SRY gene was positive in all group A and B patients but only one patient was positive in group C. Of the 8 patients in group A, 5 patients had a high XY mosaicism ratio compared to XO whereas an equal ratio was observed in the remaining 3 patients. Of the 4 male penotype patients only 1 patient had a high XY mosaicism ratio compared to XO while 3 patients displayed an equal ratio. There was no difference in associated anomaly and the degree of severity of ambiguity according to the mosaicism ratio in all patients. CONCLUSIONS: There was no definite correlation between the mosaicism ratio and phenotypic expression. Presence of SRY gene in 45XO patients may suggest MGD(mixed gonadal dysgenesis) and therefore, the evaluation SRY gene could be useful in the diagnosis of 45XO patients with ambiguous genitalia.
