The authors experienced a case of gastroduodenojejunal trichobezoar detected by ultrasongraphic examination. We thought that tricholbezoar had relatively specific ultrasonographic findings such as a broad hyperechogenic superficial bandlike rim with a complete posteior sonic shadowing and multiple linear echogenic strands on its surface representing hairs, which were better seen after water ingestion. So we were able to get the correct diagnosis of trichobezoar prior to conventional barium studies in a patient who could not be suspected suspected clinically.

Hyperkeratosis of the nipple and areola is a rare condition. We report a case of hyperkeratosis of the nipple and areola occurrinp in man with no underlying endocrirop thy or synthetic estrogenic drug therapy. The patient was not associated with epidermal nevus orichthyosis and so fitted into the nevoid form of hyperkeratosis of the nipple and areola. The clinical appearance and histological findings of the lesion were the same as those reported before. He showed a slight improvement in the color and hyperkeratcsis of the nipple and areola with 6 months use of a topical keratolytic agent and corticosteroid crearn.

Intentional delay of aftercoming siblings in multiple gestation is an infrequent occurrence in obstetrics. After delivery of an immature twin, conventional treatment calls for induction and delivery of the aftercoming sibling. However, several case reports have documented the feasibility of an expectant management. And also, as in our case, an aggressive treatment consisting of cerclage, tocolysis, and broad-spectrum antibiotics has been shown to prolong pregnancy. We experienced an unavoidable delivery of a nonviable first twin after premature rupture of membranes at 16 weeks' of gestation. The placenta was left undisturbed. Twin B was confirmed to be alive within the intact second sac. Tocolysis was started and cervical cerclage was done directly after delivery of twin A. Pregnancy was successfully prolonged, which enabled the second fetus to remain in utero and grow for another 145 days. To our knowledge, this was the longest interval between deliveries in a twin pregnancy reported in the literature. A healthy 3,050 gm male was delivered by cesarean section at 37 weeks' of gestation. Below we present this case in detail and discussed with respect to the aggressive approach undertaken to prolong gestation.

A medullary fibroma is the most common tumor found in the renal medulla and is seen incidentally in necropsy, but the usual small size and benignancy make clinical detection extremely rare. We report two cases of unusual renal medullary fibroma, incidentally discovered and accompanied by gross hematuria respectively in both sex. Radical nephrectomy and radical ureteronephrectomy with bladder cuff excision were performed because suspected to be malignant renal and renal pelvis tumor in X-ray and clinically. Histological examination revealed renal medullary fibroma. The diagnostic limitation and therapeutic dilemma associated with this condition are discussed.

PURPOSE: Status epilepticus (SE) is one of the most common neurologic emergencies in children requiring immediate aggressive intervention. Despite advances in treatment of this condition, SE is still associated with a significant morbidity and mortality. To evaluate etiology and neurologic outcome of SE is very important for improving the methods of evaluation and management of SE as well as decreasing morbidity and mortality. METHODS: We retrospectively reviewed the records of 98 children aged 1 month to 15 years who were admitted to our department of pediatrics from January, 1992 to December, 1998. We analyzed age distribution, etiology, seizure type, abnormalities of EEG and brain MRI, and neurologic outcome. We try to find any coherence between neurologic sequelae and clinical factors. RESULTS: The incidence was high in toddler age, especially younger than 3 years old (67.4%). Generalized convulsive SE was the most common type (67.3%), and 54.1% of children with SE which was the first seizure episode. Major etiology of SE in young children younger than 3 years old were febrile convulsion (54.5%) and acute symptomatic causes (22.7%). Neurologic sequelae were left in 21.4% and the mortality rate was 7.1%. The neurologic complications were highly associated with the underlying causes and the seizure durations, especially over 2 hour seizures left in 75% complications. The mortality and neurologic sequelae were higher in acute symptomatic SE than other causes. Febrile SE had usually benign course, but in four in our cases showed neurologic sequale it shows 4 neurologic sequelae cases. CONCLUSION: SE is a life-threatening neurologic condition and especially occurs in young children. The early detection of seizure etiology and aggressive management are the essential factors to decrease the mortality and morbidity rates.

PURPOSE: To evaluate the characteristic CT findings of neuroblastoma, we studied neurobalstomas. METHODS AND MATERIALS: We analysed CT findings of available 25 cases among pathologically proved 51 neurobalstomas from Jan. 1983 to Sept. 1990. RESULTS: The most frequent site of origin is adrenl gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows:Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently septated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymphnodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neurobalstomas and 25% of mediastinal neuroblastomas. The most common organ of contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. CONCLUSION: We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings.
