We present a case of transient acantholytic dermatosis which developed on the face of a 19-year-old Korean girl. Asyrnptomatic pinhead to miliary-grain sized brownish papules arranged in a somewhat band-like outbreak along the left side of the nose for about 3 months. Histopathologic findings were similar to Dariers disease. Immunoperoxidase staining showed that IgG was deposited on the intercellular area of keratinocytes around the suprabasal clefts. Skin lesions disappeared spontaneously in 5 weeks after a skin biopsy.

Early diagnosis of persistent abnormal reflexes may be of great significance to a more effective functioning of the cerebral palsied child. It is important to know the normal and abnormal reflex responses and their effect upon motor development for providing a basis for evaluation in the diagnosis and treatment of the cerebral palsied child. We studied 28 cerebral palsied children, between 1 to 12 years old, who were treated at Sam Yook Childrens Rehabilitation Center from May 1975 to December 1977. The pathologic reflexes were checked, and the relationship between pathologic reflexes and walking was compared. The following results were obtained. 1. The following were the most important pathologic reflexes in non-walking fgroup: a. Positive supporting reaction b. Protective extensor thrust c. Moro reflex 2. If they are present, the prognosis for walking ambulation was bad and surgery will not improve for the chances of walking.

Actinomycosis is a chronic, granulomatous suppurative disease caused by Actinomyces species. Actinomyces is an anaerobic, gram positive organism that requires special techniques for culture and isolation. Actinomycosis is characterized by formation of multiple abscesses, draining sinuses, abundant granulations (sulfur granule) and dense fibrous tissue. The three major clinical presentations include the cervicofacial, thoracic, and abdominal regions. Since A. israelii is a normal inhabitant of the oral cavity, to make a definitive diagnosis it must be recovered from closed tissue spaces, draining sinuses, or abscesses, or it must be shown to be invasive in histopathologic sections. The drug of choice is penicillin. Because of the dense fibrous tissue surrounding the colonies of organisms and the concentration of organisms in clusters, high doses of pharmacologic agents must be used for long periods, and radical surgical excision should accompany antibiotic therapy if possible. We report three cases of abdominal actinomycosis, preoperatively impressed as appendicitis and pelvic abscess, which was diagnosed by a histological study of operative specimens. The possible pathogenic mechanisms causing clinical symptoms are discussed.

Sparganum is a parasite infesting principally in the cats or dogs, but human infestation was also not uncommonly reported. In Korea, the reported cases of sparganosis are over 70. We experienced a case of sparganosis in scrotum. This patient, 47 year-old man, had had episodes of intake raw snakes for 6 years as a tonic since 12 years before. The removed larvae of the parasite revealed milkish-white color, flat, and glistening appearance. Life cycle and route of infection of sparganum mansoni are discussed with review of the literatures.

PURPOSE: To evaluate the efficacy of power Doppler ultrasonography (PDUS) in depicting renal infarction inrabbits during experimental renal segmental arterial occlusion, and to compare the results with those of CTscanning. MATERIALS AND METHODS: In 28 rabbits weighing 2.5-4kg, the segmental renal artery was occluded throughthe left main renal artery by embolization with Ivalon (Nycomed, Paris, France). Power Doppler ultrasonography andspiral CT scanning were performed before and at 2, 5, 8, 15, and 24 hours, and 3 and 7 days after occlusion of thesegmental renal artery. The location of infarcted areas and collaterals, as seen on PDUS and CT scans, wasevaluated by two radiologists. RESULTS: In all cases, as seen on power Doppler ultrasonography, infaretedareas-when compared with normal parenchyma, clearly demonstrated wedge-shaped perfusion defects in the kidney. Thelocation of the lesion closely corresponded to the location seen during CT scanning. After renal arterialocclusion, transiently congested capsular arteries, which were named 'capsular sign', were seen in 63% ofrabbits in the two and five-hour groups. No significant cortical rim sign was demonstrated on power Dopplerultrasonography, though it was noted on spiral CT at 15 and 24 hours, and 3 and 7 days after renal arterialocclusion. CONCLUSION: Power Doppler ultrasonography was useful for the diagnosis of renal infarction. Congestedcapsular artery seen in the early stage of renal infarction might be a characteristic finding of this condition,as seen on power Doppler ultrasonography.

Dural arteriovenous malformations may be congenital, but most dural arteriovenous malformations are acquired lesions. The acquired dural arteriovenous malformations are rarely associated with brain tumors. We describe a case of dural arteriovenous malformation at the non-dominant transverse-sigmoid sinus associated with a convexity meningioma on the same side. The lesion was spontaneously disappeared after removal of the meningioma, even though the dural arteriovenous malformation was not manipulated. The authors describe a possible pathophysiology of dural arteriovenous malformations associated with tumors at the remote area and spontaneous closure after tumor resection.

PURPOSE: To evaluate the impact of a retrotrigonal layer backup stitch (RTBS) during robot-assisted laparoscopic radical prostatectomy (RALP) on post-prostatectomy incontinence. MATERIALS AND METHODS: We compared the difference in continence recovery between 94 patients (group 1, as historical controls) and 57 patients (group 2). The only technical difference between our two groups was the incorporation of the retrotrigonal layer into the posterior aspect of the vesicourethral anastomosis (group 1: without RTBS; group 2: with RTBS). Postoperative continence recovery was defined as the use of no absorbent pads. RESULTS: In group 1, the continence rate at 3, 6, and 12 months postoperatively was 40.4%, 70.2%, and 90.4%, respectively;in group 2, the continence rate was 42.1%, 70.1%, and 89.7%, respectively. The median (95% confidence interval) time to continence recovery was four months (range, 1 to 12 months) in group 1 and four months (range, 1 to 9 months) in group 2. Kaplan-Meier curves showed no significant difference in the recovery of continence between the two groups (log rank test, p=0.629). CONCLUSIONS: A RTBS does not appear to improve urinary incontinence after RALP. Further anatomical study and prospective randomized studies will be needed to confirm this.

OBJECTIVE: To compare the accuracy of three-dimensional (3-D) ultrasound-assessed fetal thigh volumetry in predicting birth weight with that of other commonly used formulas composed of biparietal dimeter (BPD), abdominal circumference (AC), and femur length (FL) by two-dimentional (2-D) ultrasonography. METHODS: From May 1999 to February 2000 we performed a prospective study of ultrasonography on 100 pregnant women. We assessed the thigh volume of 100 fetuses using 3-D ultrasonography. Meanwhile their BPD, AC, and FL were measured by 2-D ultrasonography. All infants were delivered within 48 hours after the ultrasound examinations. RESULTS: The thigh volume assessed by 3-D ultrasonography was highly correlated with birth weight (r=0.414, n=100, p<0.0001). The 3-D formula had small mean values of absolute mean error (gm) (64.26), absolute mean error (%) (10.20+/-0.80). As well, the 2-D formulas had similar mean values. However, no significant differences in predicting birth weight were found between 3-D formula and 2-D formulas. CONCLUSION: The 3-D ultrasound method assessed by thigh volume showed better accuracy in predicting birth weight than 2-D methed. Further studies may be needed to confirm our conclusions.

PURPOSE: Traumatic rupture of the diaphragm is not easy to diagnose and often delayed. Delayed diagnosis of diaphragmatic rupture accompanied by higher chances of strangulation of herniated viscera which may result in higher morbility and mortality. The purpose of this study was to evaluate diagnostic accuracy of spiral CT, MRI and US for the diagnosis of diaphragmatic rupture in an animal model. MATERIALS AND METHODS: Small, medium, and large sized transabdominal diaphragmatic ruptures were surgically made in experimental rabbits and then followed up with spiral CT, MRI, and US at 1 day, 3 day, and 1 week after operation. RESULTS: US was superior to MRI or spiral CT in diagnosis of diaphragmatic rupture(P<0.05). The sensitivity and specificity were 94.4% and 92.9% for US, 54.0% and 85.7% for MRI, and 46.0% and 78.6% for spiral CT, respectively. The size of laceration was not related to diagnostic sensitivity in US. Sensitively of MRI and spiral CT increased as the size of laceration were larger, but no statistical significant was present(P>0.05). All experimental animals developed pleural effusion or hemothorax one day after operation. In acute phase. US and MRI were more sensitive than spiral CT in detecting diaphragmatic rupture. Spinal CT was more sensitive than US and MRI in delayed phase but without statistical significance(P>0.05) In the experimental rabbits with accompanying visceral hernia through the diaphragmatic defect, diagnostic accuracy was found equally high among three image modalities(P>0.05). CONCLUSION: This study indicates that US is the most accurate diagnostic method in detecting injury to the diaphragm in a rabbit model. The findings obtained in this experimental study can be applied to the diaphragmatic rupture of human being.
