Immature teratoma accounts for less than I percent of all ovarian teratomas and occurs commonly in young individuals, the peak incidence being in the second decade. It contains a variable mixture of mature and immature tissues in which neuroectodermal elements almost always predominate. Gliomatosis peritonei, miliary implants of mature glial tissues on the peritoneum or omentum, is an infrequently reported complication of mature or immature ovarian teratomas. We describe the first case in Korea of a 12-year-old girl with an immature teratoma and numerous glial peritoneal implants.

This report describes a case of ileal obstruction in a 31-year-old male with acute abdominal pain. A plain film of the abdomen showed segmental obstruction of small intestine. The patient underwent laparoscopic resection of the segment. Microscopic examination demonstrated foci of ulceration, submucosal edema, transmural inflammation, mural and neural hyperplasia and noncaseating granulomas, mimicking Crohn's disease. However, there were microabscesses predominantly composed of eosinophils. Furthermore, a section of an adult heterophyid trematode was identified in the crypt. Heterophydiasis usually causes diffuse enteritis. Therefore, this case with intestinal obstruction seems to be a rare manifestation of intestinal heterophydiasis.

Wet cement can cause caustic ulcers due to its alkalinity. Besides caustic ulcers frequently called cement burn, allergic and irritant contact dermatitides are common in cement workers. Alkalinity of calcium hydroxide in wet cement combined with the effect of pressure and occlusion against skin may result in cement burn. We report two cases of cement burn due to their occupational exposures.

Povidone-iodine(PVP-I) is a widely used antiseptic for the skin because of its low toxicity and high germieidal efficacy, Allergic contact dermatitis to PVP-I is known to be rare. Two patients who recently underwent surgical operations were referred to us due to pruritic well-demarcated eczematous skin lesions around the wounds. Their operation wounds had persisted in spite of the treatments using systemic antibiotics and topical antiseptics. Patch tests were performed with antiseptics including PVP-I, hydrogen peroxide, and benzalkonium chloride which had been used to dress their wounds. The patch tests resulted in positive reactions to PVP-I at the concentrations of 1% in one patient and 0.01% in another.

Contact urticaria designates a local immediate and/or delayed urticaria reaction, with swelling and redness at the sites of contact with certain agents. Fruits are the frequently causative agent for immunologically mediated contact urticaria. We report herein a contact urticaria occurring in a 20-year-old male immediately aftar contact with peach and plum, and after ingestion of plum, peach and apple. Swelling and itching sensation of lips and oral cavity, and tightness of chest were also developed ofter ingestion of plum, peach and apple.

Autograft using suction hlistered epidermis is one of the surgical therapeutic mod- alities of vitiligo, and has been successfully used by several authors. The maintenance of grafting pigment is belieued to be more important than repigmentation itself. To examine the maintenance of pigment, 22 vitiligo patients were treated by autograft using suction blistered epidermis and followed for 16.8 months. Repigmentation developed in 20 patients, Two patients were lost to follow up. Out of 20 patients, grafting pigment was maintained in 17 patients(85% ) and disappeared in three patients(15% ). By clinical subtype, the rates of maintenance were 100% in segmental type, 80% in localized type and 66% in generalized type. The best results were observed in a head and neck location and the worst rates and maintenance were in the hand. However, these differences were not statistically significant. likewise, age and sex were not factors in maintenance and repigrnentation. Based on this study, autograft using suction blistered epidermis appears to be a good therapeutic modality for stable vitiligo, particularly segmental vitiligo.

PURPOSE: Epilepsy is generally defined as a chronic condition characterized by recurrent unprovoked seizure. It is still controversial whether the long-term antiepileptic drugs(AED) treatment will be necessary in children with first unprovoked seizure. Cognitive and behavioral side effects of AEDs are especially important in developing children. Therefore the rationale of AED treatment in the children with first unprovoked seizure depends upon the seizure recurrence rate and presence of risk factors related with seizure recurrence. We are going to evaluate the risk of seizure recurrence and risk factors after a first unprovoked seizure in children. METHODS: One hundred fifty eight patients presented with a first unprovoked seizure from July, 1994 to June, 1999 were prospectively followed by regular epilepsy clinic visit or telephone interview for a mean of 27 months. We analyzed overall recurrence risk and risk factors of seizure recurrence(EEG finding, etiology of seizure, seizure type, history of prior febrile convulsions, neurodevelopmental status prior to first seizure, presence of a Todd's paresis, family history of seizures, a seizure occuring while asleep, and duration of seizure) by Cox's proportional hazards model and Kaplan-Meier survival analysis. RESULTS: In 158 patients with first unprovoked seizure, 61 (39%) patients experienced subsequent seizure. The cumulative risk of seizure recurrence was 28.5, 37.6, and 42.3% at 6, 12, and 18 months. The median time to recurrence was 3 months, with 72% of recurrence occurring within 6 months, 92% within 1 year, and 100% within 2 years. On univariate analysis, risk factors for seizure recurrence included an etiology of seizure and abnormal EEG. In idiopathic cases, the risk factor was an EEG abnormality. CONCLUSION: Many of the children with a first unprovoked seizure will not have recurrences. The recurrence risk of a first unprovoked seizure in children have statistically correlated with the etiology of seizure(cryptogenic and symptomatic) and abnormal EEG. Children with an idiopathic first seizure and a normal EEG have a particularly favorable prognosis.

Quality control survey was done on the plasma triglyceride determination of six laboratories and following results were obtained. 1) Coefficients of variation were less than 5% in 3 laboratories and over 10% in one laboratory. 2) High interlaboratory variation was inferred from the mean values ranging from 104.0~136. 4mg% (sample A) with enzyme method and 44.7~65.3 (Sample B) with acetylaceton method. 3) Establishment of normal plasma triglyceride level in Koreans and supervised quality control by the authority seemed to be urgent.
