Authors reviewed mammographic ultrasonographic and MRI findings a patient with breast cysticerocosis, which was operated and pathologically proved. Mammography showed a 1 cm sized round radioopaque lesion with curvilinear calification, which was located near the pectoralis major muscle. Ultrasonograiphic findings showed heterogenous hypoechoic cystic lesion with internal hyperechoic nodule and posterior acoustic shadowing. T2Wl and proton density MR image showed low signal intensity with cresentic high signal intensity portion. 2D-FLASH dynamic MRI showed intermediate signal intensity and peripheral signal void area, which was not enhanced with Gd-DPTA. The possibility of cysticercosis can be considered be considered when a cytic lesion is discovered near the pectoralis muscle in a patient living in an endemic area.

Traumatic optic neuropathy is one of true ophthalmic emergencies and there is no proven form of treatment for traumatic optic neuropathy. 82 cases of traumatic optic neuropathy were investigated to evaluate the effectiveness of high dose corticosteroid for the visual improvement. Age, sex, initial visual acuity, final visual acuity, interval to treatment, the type of trauma and the affected region were studied retrospectively.250 mg of Methylprednisolone was administered intravenously every 6 hours for 3 days, and then followed by tapering using oral prednisone The vision was improved in 36 of 82 cases[43.9%]. It was difficult to interpret the relation-ships between the affected region and visual improvement, the interval for each treatment and final visual acuity. However, the vision was improved in 45 of 50 cases who had an initial visual acuity of above light perception, but in the two of 32 cases with no light perception. If indicated, fifteen cases were treated with a combination of high dose corticosteroid and optic nerve decompression. In initial treatment of traumatic optic neuropathy, high dose corticosteroid was effecive. Whether or not initial visual acuity was better than light perception was a key risk factor in the outcome.

Animal models are useful tools to study the molecular basis of schizophrenia pathophysiology and efficacy of potential therapeutic agents. Schizophrenia animal models can be subdivided into three classes ; drug-induced models, genetic models, and environmental models and each model is designed based on specific traits corresponding to the characteristic symptoms of human schizophrenia patients. Psychomotor agitation and sensitivity to psychotomimetic drugs are often thought to reflect positive symptoms. Social interaction deficits and affective impairments are known to correspond to negative symptoms. Also, cognitive symptoms have been linked to the working memory impairments, attention deficits and related cognitive deficits in animals. To analyze such components in quantifiable manners, various behavioral paradigms have been developed and utilized. Here, we overview these animal models, focusing on underlying rationales for their use in the context of schizophrenia research.

We assessed the accuracy of clinical evaluation, arthrography and arthroscopy in the diagnosis of meniscal lesions in ninty knees in which arthrotomy was performed for disabling symptoms after evaluation by these three methods. At surgery, ninty-two menisci were removed, of which seventy-two were abnormal and twenty were normal. In these ninty-two menisci, correct diagnostic rate was made clinically 78%, arthrographically 70% and arthroscopically 86%. Arthrographic diagnosis was least accurate for lesions of the lateral meniscus and arthroscopic diagnosis was least accurate for lesions of the posterior horn of the medial meniscus and peripheral lesions. Based on this study, it was concluded that both the arthrography and arthroscopy are valuable technique for diagnosis of meniscal lesions.

PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

In Korea, Kerion celsi caused by T. verrucosum was first reported by Kim et al in the Honam province in 1986. Since then three mare cases have been reported in the Young Nam province. Herein present a case of kerion celsi caused by T. verrucosum from Chungcheong province. The patient, a 7-year old female, showed a 4x 4cm sized, oval, yellow crusted and boggy patch with alopecia on the scalp. She was living on a farm in a rural area of Chungcheong province. Cows on the farm also exhibited similar skin lesions on the buttock. The same T. verrucosum was identified by a characteristic colony morphology on Sabourauds dextrose agar and chains of chlamydoconidia with mycologic stain from scales of lesions of patient and cows. This skin lesion was successfully treated with griseofulvin.

The distribution of pemphigus subclass autoantibodies in a patient with pemphigus vulgaris (PV) has been investigated by semiquantitative indirect immunofluorescence (IIF), using the HP series monoclonal antibodies specific for four human IgG subclasses on human foreskins. IgG1 and IgG4 intercellular substance-specific autoantibodies were detected in the serum of the patient, whereas IgG2 and IgG3 autoantibodies were absent. In addition to foreskins, human tonsillar epithelia were used as substrates of IIF for detecting the PV autoantibodies and it was one of satisfactory substitutes for monkey esophagus.

Neonatal hepatitis(NH) and congenital extrahepatic biliary atresia(BA) are two major causes of neonatal cholestasis. The method of therapeutic trials for each disease is essentially different. Nonetheless it is very difficult to differentiate these diseases histologically, since most of the hepatic changes are mutual in both of them. This study is to aimed to find out major differences between the two by scoring various histological parameters. A total of 63 consecutive liver biopsies taken from 54 patients with suggested NH and BA were examined by applying morphometric scoring system. The detailed clinical histories, laboratory data including serology for HBsAg and TORCH infection and radiologic operative findings were reviewed. Among 54 patients, 27 were diagnosed as NH and 20 as BA. In two cases, features of both diseases were coexistent. The pathological diagnosis was not compatible with the final diagnosis in 5 cases(10.7%). In all of these 5 cases, biopsy had been performed at the age of one to two months. The seropositivity for TORCH was 59.3%(16.27) in NH, but 25.0%(5/20) in BA. Serum AST, ALT and alpha-fetoprotein values were higher in NH, and total bilirubin in BA. Of various histological parameters, scores of portal fibrosis, bile duct and ductular proliferation and bile thrombi were much higher in BA, and at the age of less than 2 months, extramedullary hemopoiesis(EMH) was found much more frequently in NH. Giant cell transformation of hepatocytes(GCT) was more commonly observed in NH. The numbers of GCT and EMH were particulary plentiful when the patients' sera were positive for HBsAg or TORCH. These results indicate that portal fibrosis, biliary proliferation and bile thrombi are the three major histologic features of BA, and therefore erroneous histological diagnosis may ensue when scores of those features are low as in some early BA.

This study is based on 155 patients of congenital me colon. For the diagnosis, 93 cases were histologically proven and the remaining 63 cases were diagnosed on clinical basis including barium enema or surgical gross findings. On histologic examination, 80 cases(86%) showed typical features of absence of ganglion cell in the myenteric plexus and the 13 cases(14%) had atypical features which were segmental absence Of ganglion cell in one case. There we 127 males(82%) and 28 females(18%). The age at diagnosis was younger than 30 days in 87 cases(56%), I month to 1 year in 39 cases(25%) and older than I year in 29 cases(18%). The levels of aganglionosis were variable: short segment (rectosigmoid) in 134 cases(86%), intermediate segment (more proximal colon) in 14 cases(100%). and 6 cases(4%) had total aganglionosis. Common clinical presentations were abdominal distention, delayed meconium passage or bilious vomiting in neonate, and chronic constipation in infancy or childhood. Following initial colostomy or ileostomy, a definitive procedure was performed in 151 cases(Duhamel type in 150 cases; Soave type in 2 cases; Swenson type in 3 cases). Frequently associated problems after definitive procedure were persistent constipation(ll%) due to septum formation, fecaloma, remnant aganglionic segment and rectal stenosis. Overall mortality rate was 4%, and increased mortality was associated with enterocolitis(14%) which was the most frequent cause of death. The follow-up study longer than 3 months was available in 138 patients who underwent a definitive procedure(mean 2 year 11 months). Seventy-three cases(53%) had normal bowel function, 38cases(27.5%) had occasionally used enema or stool softners, and 27 cases(19.5%) had severe constipation or soiling. The bowel habit improved with time, and were considered normal in 60% of patients after follow-up more than 3 years. The results of definitive procedures for congenital megacolon including Duhamel operation was satisfactory, and long-term follow-up appeared an important and critical component of patients'care.
