Most of malignant melanoma of skin had occurred in transformation from benign nevi(Webster, 1944), especially most frequently from junctional nevi of them. which was characterized by flat surface, dark-brown color and hairlessness(Ackermen, 1948) Blumberg (1972) introduced five levels of hietologic invasion of malignant melanoma described by Clark et al. Morton(1970) reported various measures of treatment such as surgery combined with radiotherapy or with chemotherapy or with recent immunotherapy with good result. The authors recently experienced 24-yeas old male soldier patient with malignant melanoma on hypothenar region of right palm. The pathologic investigation including electronmicroscopical aspect was carried out and are presented. Treatment consisted of the resections of right axillary lymph nodes and the lesion in situ on the hypotherar region of right hand, pedicle skin graft to right hand from abdomen, and immediate postoperative immunotherapy with intradermal injection of 1.0 cc. of B.C.G. daily on extensor surface of both thighs in turn, which lasted for about 3 months duration to find good result.

Twenty newly admitted acute schizophrenic patients were treated with haloperidol for 6 weeks. HVA and 5-HIAA were sampled at baseline, 3days after initial neuroleptic dose, and after 1, 2, 3, 4, 6 weeks of treatment. Nine patients were classified as responders in this prospective haloperidol treatment trial. They had a score of change in the BPRS total scores of 25% or greater. Eleven patients were classified as nonresponders, based on a score of changes in the BPRS total scores of less than 25%. 1) There was no significant difference in plasma HVA/5-HIAA ratio between responder and non-responder before and after haloperidol treatment. 2) There was no significant correlations between plasma HVA/5-HIAA ratio and BPRS total scores. This study could not support the hypothesis that neuroleptic treatment would be effective by changing dopamine and serotonin function and/or by altering their interaction.

Islet transplantation has been considered as an attractive procedure due to its simplicity, and because it can improve glycemic control in type 1 diabetic patient with hypoglycemic unawareness. In 2000, Shapiro et al. at the University of Alberta in Edmonton reported successful reversal of type 1 diabetes by pancreatic islet transplantation in seven patients with severe hypoglycemia, but no kidney disease. After the Edmonton milestone report, there has been an exponential increase in clinical islet transplantation activities. However, the revived enthusiasm regarding clinical islet transplantation after the landmark Edmonton trial has been decreased by the long-term results. The aim of this review is to summarize history, current status and the perspective of islet transplantation in patients with type 1 diabetes.

This study was done to examine changes of plasma homovanillic, acid(HVA), 5-hydroxyindoleacetic acid(5-HIAA), and HVA/5-HIAA ratio during an 8-week clozapine trial and to investigate the relationship between the plasma monoamine metabolites and treatment responses. Twenty-seven chronic schizophrenic patients were treated for 8 weeks with clozapine. The psychopathology was assessed at baseline just clozapine trial and then every 2 weeks until the end of 8-week clozapine treatment using the positive and Negative Syndrome Scale(PANSS) and the Clinical Global Impression scale(CGI). The plasma HVA and 5-HIAA levels were measured also biweekly using high preformance liquid chromatography with electrochemical detection method. Plasma HVA and 5-HIAA levels were significantly decreased during a 8-week chozapine treatment, although plasma HVA/5-HIAA ratio showed no significant change. The changes of plasma HVA levels were in significant correlations with the changes of PANSS positive scores, of general psychophathology scores, and changes of total scores. The changes of plasma 5-HIAA levels were in significant correlations with the changes of PANSS negative scores. But the changes of plasma HVA/5-HIAA ratio had no significant correlation with any PANSS subscale score changes. 48% of the patients treated with clozapine was categorized as responders, who showed at least a 20% decrease in PANSS total score and a CGI severity score of mildly ill or less(< or =3) of the end pint of the study. The baseline plasma HVA levels and HVA/5-HiAA) ratio were significantly higher in responders(N=13) than in nonresponders(N=14). But no significant difference in the change of plasma HVA between responders(40.3% decrement) and nonresponders(3.1% increment). But no significant difference in the change of plasma 5-HIAA and the change of plasma HVA/5-HIAA ratio between responders and nonresponders were observed. These results suggest that the antipsychotic effect of clozapine on positive symptoms may be associated with dopaminergic blocking activity, and that on negative symptoms may be associated with serotonergic blocking activity. The baseline plasma HVA levels and the change of HVA levels from baseline may be useful predictors of treatment response with clozapine.

We have experienced a case of 13 ring chromosome in a 40-month-old girl who demonstrated psychomotor retardation with delayed speech, growth retardation, hearing loss(left), microcephaly, trigonocephaly with flat occiput, hypertelorism, epicanthal folds, microophthalmia, broad prominamt nasal bridge, high arched palate, micrognathia, large auricles and other anomalies. Cytogenetic studies of peripheral blood lymphocytes with differential staining of chromosomes revealed 46, XX, r13. Her parents' karyotypes were normal. We reported the case with the review of the associated literatures.

We report a case of giant hydronephrosis due to congenital ureteropelvic junction obstruction in a 7-month-old female infant with contralateral renal agenesis. Congenital renal agenesis is an uncommon congenital condition that results from a failure of induction of the metanephric blastema by the ureteral bud and fifteen per cent of cases show anomalies of the contralateral kidney. An excretory urogram and abdominal CT scan of the patient revealed nonvisualization of left kidney, and a retrograde pyelogram showed markedly dilated extrarenal pelvis crossing over the mid-line because of narrowing of ureteropelvic junction. However, the other combined anomalies were not identified. A successful dismembered pyeloplasty was performed after temporary urinary diversion with percutaneous nephrostomy for 4 weeks.

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.

BACKGROUND: Intracranial lipomas are uncommon benign lesions of the central nervous system. They preferentially occur near the midline, most frequently in the pericallosal cistern, and are often associated with various neurologic and systemic anomalies. Since the advent of CT scanning and MR imaging, unexpected findings of intracralial lipomas have increased. We identified 11 cases of intracranial lipomas diagnosed by CT and MR and analyzed their characteristic clinical and radiologic findings. METHODS: We retrospectively reviewed 11 cases of intracranial lipomas. MR was used in all cases and CT in three. RESULTS: There were seven men and four women whose ages ranged from six months to 76 years, with a mean of 39 years. Six (55%) lipomas were located in the quadrigeminal plate and five (45%) in the pericallosal area. The pericallosal lipomas were divided into three cases of curvilinear type and two cases of tubulonodular type. Of the six quadrigeminal lipomas, five cases (83%) were associated with either hypoplasia of the unilateral (four) or bilateral (one) superior and/or inferior colliculus. One case of quadrigeminal lipoma was associated with hypoplasia of the cerebellar vermis, agenesis of the septum pellucidum, and glioblastoma multiforme. All cases of pericallosal tubulonodular type were associated with dysgenesis of the corpus callosum and enlarged ventricles. However, all cases of pericallosal curvilinear type were not associated with other anomalies. Four (36%) cases found incidentally were asymptomatic. Seizure was the most frequent clinical presentation in five (45%) cases, followed by headaches in three (27%) and mental retardation in one (9%). Of five seizures cases, three had secondary generalized seizures and two had generalized tonic clonic seizures. CONCLUSIONS: Quadrigeminal and pericallosal lipomas were the most common types of intracranial lipomas. Sixty-three percent of the lesions were associated with adjacent brain malformations of varying degrees. Four cases were asymptomatic, while the others presented with seizures, headache, and mental retardation. (J Korean Neurol Assoc 19(2):149~154, 2001)
