The present study was designed to measure the activity of purine nucleosiae phosphorylase(PNPase) in sera and lymphocytes af peripheral blood from patients with allergie contact dermstitis and drug eruption since PNPase activities are known to be decreased in cell-mediated immune deficieney diseases. The PNPase activities in sera and lymphocytes of normal subjects were (7.2 +1.05) * 105 unit/L of sera and (1.85+0.38) unit/102 lymphocytes, respectively. In allergic contact dermatitis, the PNPase activities in sera and lymphocytes of patients were (3.9+0.78) *105 unit/L of aera and (0.69+0.23) uoit/102 lymphocyteis, which were signifieantly lower than those of normal subjects. There were no differences in PNPase activities of sera and lymphocytes between drug eruption patients and normal subjects. From these results, it is suggested that the lowered PNPase aetivity in allergie contact dermatitis might be associated with abnormal lymphocytes differentiation or activation or some other unknown mechanism, since lowered PNPase activity in allergic contact dermatitis is in contrast to the generally accepted concept that enhanced status of CMI in ACD will lead to the increase in PWPase activity.

We experienced 53-year-old male patient, who had an eczematous verrucous plaque measuring 6 x 4cm in diameter on the nasal bridge for 4 months. On physical examination, there was no abnormality except of palpable bean sized nodule on the left side of chin for 2 months. The overlying skin of the nodule is a quite normal appearance. The skin biopsy of the nodule showed the charact.eristic a.rrangement of the infiltrate in three zones. And the result of fungus culture of the thin tissue slice on Sabouraud media diagnosed fungal infection due to Sporotherix .schenkii. The treatment began with oral ketoconazole for 4 weeks, and the medication was interrupted for 2 weeks, because of no favorable effectiveness. On his revisit, a chain of painless nodules along lymphatics palpated on the right side of his f ace. We changed the therapy into saturated solution of potassium iodide(KI) with 0.25ml(5 drops) orally there times a day and was gradually increased administration of KI, And no side effects were noted. The patient was treated for a. total of 18 weeks, which included 6 weeks of treatment following clinical resolution.

PURPOSE: To evaluate the usefulness of pulmonary function test for the prediction of successful weaning and extubation from the ventilator in very low birth weight(VLBW) infants with chronic lung disease. METHODS: This study included 15 VLBW infants(<1,500 g) with chronic lung disease who were admitted to Neonatal Intensive Care Unit of Samsung Medical Center from July, 1995 to June, 1996. They had extubation failure more than one time. This study was performed by reviewing of patients records retrospectively. The extubation criteria were based on clinical status, ABGA profiles and ventilatory parameters. At the time of last extubation failure and final success, we analyzed the distribution of age and weight of infants, ventilator profiles, ABGA profiles, dynamic and static pulmonary function test profiles measured by Bicore CP-100R from the infant with ventilator assistance daily in line monitoring. The paired T-test and linear logistic regression analysis were used to compare the variables between the evets of extubation failure and success. RESULTS: At the time of successful extubation, expiratory airway resistance was significantly lower and minute volume was significantly higher in dynamic pulmonary function test and respiratory system resistance was significantly lower in static pulmonary function test(P<0.05). In ventilator parameter, Fi02 and respiratory rate were lower at successful extubation(P<0.05). No statistically significant differences in ABGA profiles were seen between unsuccessful and successful extubation. CONCLUSION: The pulmonary function test is a useful predictor for successful weaning and extubation in VLBW infants with chronic lung disease. Among various parameters of pulmonary function test, expiratory airway resistance, minute ventilation and respiratory system resistance are suggested as successful weaning parameters.

A 19-year-old man was referred to Seoul National University Dental Hospital for evaluation of a large painless swelling of the left mandibular angle area in August, 1999. The growth had been first noted 6 years ago. He had visited other hospital in 1997. In spite of the treatment given at the hospital, the mass continued to grow rapidly. Conventional radiographs in 1999 showed an expansile, lobulated, and destructive lesion of the left mandibular body. CT scan demonstrated an expansile mass with a corticated margin. Bony septa were seen within the lesion. Internal calcification noted on the bone-setting CT image, and corresponded to the hypointense area in T1-weighted MRI image. MRI clearly delineated the extent of the lesion which had heterogenous intermediate signal intensity in T1-weighted images and heterogenous hyperintense signal intensity in T2-weighted images. The lesion was well-enhanced. Histopathologically, the lesion was completely encapsulated. Multinucleated giant cells were presented in a fibrous background, demonstrating a storiform pattern. Areas of osteoid rimmed by a few osteoblasts were scattered throughout the lesion. Inflammatory cells, blood vessels, and hemosiderin deposition were also shown. CGCG may show lots of internal calcification foci on the CT, and varied signal intensity in MRI. More cases will be needed to understand the features of the CT and MR finding of CGCG.

Allergy to latex gloves has been described as an unusual complication during labor. However, IgE mediated hypersensitivity reaction to natural rubber have recently been identified as an international health problem. In this first case report in Korea, latex anaphylaxis during labor is described in an operating room nurse who has been continuously exposed to latex gloves. Because of the increasing frequency of latex allergy, obstetrician should take care and give more attention to the clinical history, as well as be aware of this possibility especially in high risk groups.

PURPOSE: Systemic Candidiasis has become an increasingly important cause of morbidity and mortality in NICU infants. Severe infections caused by non-albicans Candida species have been increasingly reported in NICU infants. The purpose of the present study was to compare relative severity, mortality rates for C albians(CA) and C parapsilosis(CP) infections in our NICU. METHODS: This study included 16 infants with systemic candidiasis who were admitted to the Neonatal Intensive Care Unit of Samsung Medical Center from Oct. 1, 1994 to Aug. 31, 1998. Systemic candidiasis was defined as candida recovery from blood with clinical symptoms and signs of infection. Systemic candidiasis was diagnosed in 16 infants, 11 with CA and 5 with CP. Retrospective analysis of the medical records of patients with systemic candidiasis was performed. The analysis included demographic findings, clinical feature, hospital course, morbidity and mortality. RESULTS: No differences were found between CA and CP for birth weight, sex, gestational age, age or weight at onset, presence of necrotizing enterocolitis, severe ROP, prior duration of antibiotics, endotracheal intubation, parenteral nutrition, steroids, or central line. Infants with CA were more likely to have antecedent thrush and perineal Candida derrnatitis(P<0.05). Infants with CP were more likely to have catheter-related infection(P<0.05) and treated with more curnulative dose of Amphotericin B and for a longer duration than those with CA(P<0.05). CONCLUSION: Though both pathogens occur in similar NICU infants and can cause severe disease, CA appears more likely to result in complications than CP.

The primary lymphoma of the liver is a rare disease. We report a case of primary hepatic T-cell lymphoma associated with crescentic glomerulonephritis. The case, a 53-year-old male was presented with a 2-year history of hepatic mass and a 1-month history of foamy urine, rapidly progressive azotemia, and oliguria. The kidney biopsy revealed diffuse crescentic glomerulonephritis. The result of immunohistochemical study of liver biopsy specimen was consistent with non-Hodgkin's lymphoma in T-cell lineage. Because renal function was deteriorated rapidly and there were signs of volume overload, hemodialyses were performed. Although the patient received 2 cycles of combination chemotherapy with CHOP(cyclophosphamide, vincristine, prednisolone, and doxorubicin), he did not respond and died of sepsis.

Congenital intrahepatic portosystemic shunt is a rare entity and is mostly reported in adults. In embryonic period, the vitelline vein is broken up into the vitelline sinusoids, which become the intrahepatic portal vein branches and the hepatic veins. The portosystemic venous shunts may develop from embryonic vascular remnants, including the vitelline vein and ductus venosus. We report for the first time in Korea a case of congenital intrahepatic portosystemic shunt in a newbom infant presenting with congestive heart failure and hepatomegaly, successfully treated by coil embolization via umbilical vein.

Pendred syndrome is an autosomal recessive genetic disorder, which is characterized by sensorineural hearing loss, goiter and a positive perchlorate discharge test. It is caused by mutations of the PDS gene, and its clinical characteristics vary widely. The thyroid function in most cases is normal, or shows only mild hypothyroidism. In Pendred syndrome, there is an organification defect that leads to defective thyroid hormone synthesis, followed by chronic TSH stimulation. Herein is reported a case of a follicular thyroid carcinoma associated with Pendred syndrome. To our knowledge, this is the first case reported in Korea. The patient presented with a huge anterior neck mass, sensorineural hearing loss and a positive perchlorate discharge test. Fine needle aspiration cytology suggested malignancy of the thyroid, and a total thyroidectomy, with central compartment node dissection, was performed. The pathology from the thyroid mass showed a poorly differentiated follicular thyroid carcinoma
