PURPOSE: In Korea, there was no specific guidelines for the management of benign prostatic hyperplasia (BPH). We reviewed the practice patterns of Korean urologists in the management of BPH and aimed to describe the need to develop specific guidelines. MATERIALS AND METHODS: A probability sample was taken from the Korean Urological Association Registry of Physicians, and a structured questionnaire, that explored practice patterns in the management of BPH, was mailed to a random sample of 251 Korean urologists. RESULTS: For the initial evaluation of BPH, most urologists routinely performed prostatic specific antigen (PSA) (96.4%), digital rectal exam (94.4%), international prostate symptom score (IPSS) (83.2%) and transrectal ultrasound (79.2%). Symptom assessment (36.4%) followed by transrectal ultrasound of prostate (TRUS) (20.0%) was considered as the most important diagnostic examination affecting the decision about individual treatment options. Almost all urologists (92.2%) chose medical treatment as the first-line treatment option for uncomplicated BPH with moderate symptoms. Of the respondents, 57.2% had prescribed alpha blocker and 41.6% alpha blocker plus 5-alpha reductase inhibitors as the medical treatment option for BPH. The prescription of 5-ARIs was dependent on the size of the prostate and the severity of symptoms. CONCLUSION: The results of our current survey provide useful insight into variations in the clinical practice of Korean urologists. They also indicate the need to develop further practical guidelines based on solid clinical data and to ensure that these guidelines are widely promoted and accepted by the urological community.

A 44-year-old man was cutting an outer plate of a ship, at a depth of 25 m below sea level. Following a sudden explosion, he was discovered unconscious and was carried to the surface by other divers. There was no evidence of vital signs upon arrival at the hospital. Postmortem computed tomography, which was performed prior to autopsy, revealed massive pneumocephalus in the brain, pneumohemothorax, diffuse lung contusions with multiple traumatic lung cysts, air-fluid level in the cardiac chamber of the chest, and pneumoperitoneum in the abdomen. Postmortem external examination showed a circular abrasion on the jaw, diffuse subcutaneous emphysema, and contusion in the right upper arm. An internal examination revealed intravascular air bubbles in all four chambers of the heart, and diffuse pulmonary trauma including contusion, laceration, and multiple traumatic cysts. Blast injury to the chest, and air embolism due to the underwater explosion were established as the underlying cause of death.

This retrospective study was undertaken to provide information when considering aspects of future prevention and quantifying demand fir medical services. And it comprised 835 patients with facial bone fractures in various accidents and treated in the department of Plastic and Reconstructive Surgery, the Yeungnam University Hospital during the past five years from January 1991 to December 1996. The medical records of this 835 patients(1,210 fractures) were reviewed and analyzed in order to obtain the clinical pattern and understand the therapeutic tendency. The following results were obtained; 1. The greatest number of patients were sustained facial bone injuries between midnight and 3:00. The monthly incidence showed in September at the most and at the least in December. The increase of facial bone injuries of 11.3% per year was shown. 2. The mean age of patients was 30 years. The most prevalent age group was at third decade(31.9%). Males were predominated more than female(3.6 : 1). 3. The most common cause was traffic accidents(41.6%) followed by violence, fall, industrial accidents and others. 4. The most common fracture was found in the nose(35.1%) followed by mandible(22.6%), zygoma(21.1%), and maxilla(11.2%). 5. Associated injuries were as following order of frequency; ophthalmologic injury(21.0%), other facial bone fractures(18.2%), head injury(10.2%). 6. Open reduction was used for 53.9% of total cases while 40.6% of total cases required closed reduction, and 5.5% of total cases treated conservatively. The complication rate was 18.5% and complications were as following order of frequency; facial asymmetry(37.2%), diplopia and enophthalmos(19.4%), and local infection(12.8%).

Castleman's disease is a benign disorder characterized by hypervascular lymphoid hyperplasia. The etiology of the disease is still unknown. Although it may occur at the various sites such as peritoneum, retroperitoneum, pelvic lymph node, muscle and lung, it occurs most commonly at the mediastinum. Even though specific pathophysiologic relations are still not clearly determined between two different histologic types -hyaline vascular type and plasma cell type-, there were several previous reports dealing with the plasma cell type transformed or progressed into different types of malignancies such as malignant lymphoma, Kaposi's sarcoma and Hodgkin's disease. We experienced a case of plasma cell type Castleman's disease that transformed into a malignant lymphoma and report this case with review of literatures.

PURPOSE: A scoring system could be clinically useful in determining cases in which a throat culture may be omitted or in cases whether antibiotics may be initiated or not. We propose to make a clinical guideline of antibiotics administration in patients with pharyngitis. METHODS: From Apr. 1996. to Mar. 1997, throat cultures were taken from 321 cases (72 cases from Kyung-Hee Medical Center, 249 cases from 3 local pediatric clinics). On the first day of visit, 9 clinical items on a score-card were checked and a tentative diagnosis for streptococcal or non-streptococcal infection was made. These clinical scores were compared with the results of the throat swab cultures. RESULTS: Of 321 cases with pharyngitis, 55 cases (17%) proved to have group A streptococci by throat culture. The positive culture rate of group A streptococci was 18.5% from 3 local pediatric clinics, and 12.5% from Kyung-Hee Medical Center. The positive culture rate of group A streptococci were 40% in above 31 points of score, 31.5% in 29 to 30 points, 20.5% in 27 to 28 points. The sensitivity and specificity of the scoring system using a score at least 28 above points were 71% and 67%, respectively. CONCLUSION: The clinical diagnosis of streptococcal pharyngitis indicates that patients age 5 to 10 years, findings of abnormal pharynx, high fever and no past history of antibiotics use. Further modification of the scoring system for diagnosis of streptococcal pharyngitis should be made to prevent antibiotics abuse and correct diagnosis of pharyngitis.

Relapsing polychondritis is an uncommon disease manifested by episodes of progressive inflammation and destruction of cartilage. While the cause remains unknown, an autoimmune pathogenesis appears likely. Characteristic features include auricular chondritis, arthritis, nasal chondritis, ocular inflammation, respiratory tract involvement and audiovestibular damage. The clinical course of patients may vary from a relatively benign illness free of clinically evident visceral involvement, to one of episodic or smoldering activity with variable intensity, to a f ulminant illness and death within months of diagnosis. Dapsone, corticosteroid and immunosuppressive agent remain the effective therapies. We have experienced a case of relapsing polychondritis and active pulmonary tuberculosis in a 69-year-old man. He suffered from arthralgia and swelling of joints for several months on the first admission and initially was diagnosed as pseudogout based on polyarthritis and chondrocalcinosis of right knee joint. During follow-up, chondritis of both auricles and nose, which was proved by the biosy of right auricle, and relapse of polyarthritis were developed. His spu tum smear for acid-fast bacillus was postive on the second admission. Then he was diagnosed as relapsing polychondritis and active pulmonary tuberculosis and has achieved improvement with medication of dapsone and antituberculosis drugs according to susceptability test during followed-up. Thus we report this case with literature review.

BACKGROUND: Nitrovasodilators are known to induce hypotension through activating nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) pathway. By inhibiting the breakdown of cGMP, sildenafil citrate may augment the nitrovasodilator-induced hypotension. The present study was aimed to investigate whether sildenafil would reduce the dose of nitrovasodilators needed to induce the hypotension. METHODS: Ten mongrel dogs were acutely instrumented with a femoral artery catheter and a pulmonary artery catheter. They were intravenously given sodium nitroprusside (SNP; 1-16ng/kg/min) or nitroglycerin (NTG; 2 - 32ng/kg/min) to induce hypotension. The study was composed of two occasions in each animal: one with sildenafil pretreatment (1 mg/kg IV followed by 0.3 mg/kg/h) and the other without to serve as control, one week apart. Hemodynamic parameters were continuously monitored. Plasma cGMP concentrations were measured by radioimmunoassay. RESULTS: Both SNP and NTG produced dose-dependent reductions in mean arterial pressure (MAP) without affecting the heart rate in both the control and sildenafil groups. Systemic vascular resistance index (SVRI) and mean pulmonary arterial pressure were also decreased. However, SNP caused a greater reduction of MAP and SVRI in the sildenafil group than in the control group; whereas, NTP caused similar reductions in both groups. Neither SNP nor NTG altered the plasma cGMP concentrations. Sildenafil increased the plasma cGMP concentration, which was further increased by SNP, but not by NTG. CONCLUSIONS: These results indicate that sildenafil may reduce the dose of SNP, but not that of NTG needed to produce hypotension in the dog. The potentiation of SNP-induced hypotension by sildenafil may be related to an augmented cGMP effect.

An anomalous left coronary artery from the pulmonary artery(Bland-White-Garland syndrome) is a rare congenital malformation and sometimes fatal. It is caused by an abberant endothelial budding from or an anomalous division of the truncus arteriosus. Echocardiography (transthoracic and transesophageal) and angiographical imaging are essential for the diagnosis of this anomaly. Corrective Surgery is recommended due to its fatal natural course. A case was diagnosed in a 45-year-old man who presented with intermittent palpitation. This patient was successfully treated with closure of anomalous left coronary artery orifice combined with right saphenous vein graft anastomosis.
