PURPOSE: To determine the metabolic characteristics of recurrent stone formers (RSF), we investigated urinary lithogenic factors. MATERIALS AND METHODS: The 24-hour urine samples of 151 RSF (114 men, 37 women) and 70 normal controls (33 men, 37 women) were analyzed for excretion rate differences of lithogenic and inhibitory constituents such as volume, sodium, phosphorus, uric acid, calcium, magnesium, oxalate, and citrate. The incidence and spectrum of metabolic abnomality in REF were aldo determined. RESULTS: The RSF showed significantly increased excretion of phosphorus (p=0.004), uric acid (p=0.003), and calcium (p=0.007) and decreased in that of citrate (p=0.044). No significant differences were found between the RSF and normal controls with regard to the excretions of sodium, magnesium, oxalate, and volume. The most frequent metabolic abnormality in RSF was hypocitraturia (43.7%), followed by hypernatriuria (41.7%), hypercalciuria (23.2%), and hyperuricosuria (20.5%). At least one metabolic abnormality was found in 118 of out of 151 RSF (78.1%). CONCLUSIONS: Our results showed that RSF had different urinary excretions of citrate as well as phophorus, uric acid, and calcium compared to the normal subjects and metabolic abnomalities were found up to 80% of them. The 24-hour urine study would be an effective means for metabolic evaluation in RSF although diagnostic accuracy increases with repeated examination.

Paget's disease of bone (osteitis deformans), a chronic osseous disease of unknown etiology, is extremely rarein Asia although well known in western countries. This disease is characterized by the simultaneous absorption ofbone and the new bone formation of abnormal character affecting middle and later age groups. The authorsexperienced a case of monostotic Paget's disease involving left pelvic bone in 56-years old female. To ourknowledge, this is the first cas report of monostotic Paget's in Korea.

Photodynamic therapy(PDT) is a treatment modality by highly reactive oxygen intermediates generated through the interaction of light with a photosensiziter. It has been shown to be an effective treatment for various cutaneous and noncutaneous malignancies. It is efficient for the curative and palliative treatment of epithelial skin tumor in situ or early invasive lesions. In effect, it is a useful alternative treatment for the lesions located on anatomically difficult areas or the large-sized lesions. We treated a case of Bowen's disease arising on the plantar area and 3rd and 4th toewebs of left forefoot in a 61-year-old man with PDT using the hematoporphyrin derivative, porfirmer sodium(Photofrin, Russia) as a photosensitizer and gold vapor laser as a visible light source. The outcome showed partial clinical improvement after about 2 months' follow-up.

The ultrasonographic features in 26 cases of blunt testicular trauma were reviewed. Ultrasonography diagnosed correctly in 11 surgically proven cases of testicular rupture. There were three false-positive cases, two with a large scrotal hematocele and one with epididymis rupture. there were no false-negative cases. The sensitivity and specificity of ultrasonographic diagnosis were 100% and 80% respectively. The positive and negative predictive values were 78. 6% and 100% respectively. Therefore, the negative diagnosis by ultrasonography can warrant conservative therapy.

A retrospective review was performed of 297 patients admitted to Chung Ang Gil Hospital between June 1995 and December 1996 with a diagnosis of blunt chest trauma. Of these patients, 34% suffered either immediate or delayed complications. Immediate complications included hemothorax in 58.8%, pneumothorax in 26.5%, and pulmonary contusion in 20.5%. Delayed complications occurred in 9.1% of patients overall; these included pulmonary contusion in 12.7%, pneumonia in 9.8%, pulmonary embolism in 2%, poeumothorax in 2%, and hemothorax in 2%. The mean age of the patients were 43 years. 210 patients(70.7%) were under age 50 and 87(29.3%) were 50 years of age or older. Male to female ratio was 1.9:1. Mean Initial Revised Trauma Score (RTS) and the Injury Severity Score (ISS) were 7.10+/-0.94 and 14+/-8.69, respectively. There were associated injuries in 225(75.8%) patients. Overall mortality rate was 7.1% and the mortality rate was significantly greater in patients with a RTS<6, ISS>or=16, associated injuries, advanced age(50 years of age or older), and pulmonary complications. Pulmonary complications were significantly greater in patients with a RTS<6, ISS>or=16, and an associated injuries.

Recent advent of 64-multidetctor (MD) CT enables more coverage of Z-axis in the perfusion imaging. The purpose of this study was to evaluate the clinical usefulness of perfusion CT by using 64-MD CT in detecting the lesion in patients with acute stroke. The perfusion CT was performed by using 64-MD CT in 62 consecutive patients who were initially suspected to have subacute ischemic stroke symptoms during the period of recent 9 months. These patients had subacute stroke (n=62). CT scanning was conducted with Jog Mode which provided 16 imaging slices with 5 mm of slice thickness, and 8 cm of coverage in Z-axis. Scan interval was 1 seconds for each imaging slice and total 15 scans were repeated. After CT scanning, perfusion maps (CBV, CBF, MTT and TTP) were created at Extended Brilliance Workstation. The CBV and CBF maps showed that lesions were smaller images. While on the MTT and TTP map lesions were seen to be larger fifty-one were large than they appeared on these images. Two slices of perfusion maps obtained at the level of the basal ganglia were chosen to simulate conventional older perfusion CT with 8 cm of coverage in Z-axis. TTP and MTT maps may be clinically useful for evaluation of the penumbral zone in cases of aubacute cerebral ischemic stroke. The perfusion CT is useful in the assessment of acute stroke as an initial imaging modality.

PURPOSE: The extent of ESWL(Extracorporeal Shock Wave Lithotripsy), a treatment for urinary calculus, shows gradual development and the treatment has become generally known as a noninvasive, safe, and efficacious method. Although the testicular effects are not within the vicinity of shock waves in carrying ESWL as a treatment for urinary calculus, research was initiated to examine effects which shock waves might cause on the testis. MATERIALS AND METHODS: After applying shock waves at intensity 4 for 1,000 times to the testis of Sprague Dawley immature rat, the histopathologic changes within the tissue of testis were observed after 1, 7, 14, 28 days, respectively. RESULTS: In the case of the experimental group having shock waves on the testis, destruction of seminiferous tubules, necrosis, and hemorrhage were found out a%or a day. One week later the atrophy of seminiferous tubules, interstitial fibrosis, and a small portion of chronic inflammatory cell appeared The capillary proliferation near the testis capsule also appeared. Two weeks later somewhat atrophied seminiferous tubules and proliferation of Leydig cells appeared. Diversely atrophied seminiferous tubules, diffusion of Leydig cell proliferation, calcified tubules, and foreignbody reaction were discovered after 4 weeks. As times went on, the tendency of recovery appeared. CONCLUSIONS: Noxious influences such as testicular atrophy and disturbance of spermatogenesis occurred in inflicting immediate shock wave on the testis. Therefore the need of more researches concerning long-term sequelae and the influences on the human body should be taken into consideration.
