Esophageal ulcers induced by doxycycline is a rare complication. These patients usually complain of sudden onset of symptoms, ie acute substernal or chest pain and odynophagia without prior hietory of esophageal syraptoms. On esophagoscopic examination, there are upper or midesophageal ulcers, which heal after diseontinuation of the drug within 2 weeks. A history of ingestion of the doxycycline,with liquid jost before bedtime can be elicited. The exact eause of the xaucosal ulceration is not clear, but a direct irritant effeet on esophageal mucosa seems most likely. We report 5 cases of esophageal uleeration secondary to the ingestion of doxycydine. Esophagoscopy revealed esophageal ulcers in all patients and the patients hecame asymptomatic following stopping of tbe drugs and taking antacids.

PURPOSE: Neurogenesis in neonatal period after birth occurs consequently through a series of neuronal stem/progenitor cell proliferation and differentiation. This stage is critical for determining of normal development and maturation of the brain throughout the life. Therefore, exposure to a certain physical or chemical factor(s) during pregnancy can result in serious damage in the developing brain. Bisphenol A (BPA), a plasticizer, is generally known as an endocrine disruptor exhibiting adverse effects when exposed to animals under experimental conditions. The purpose of this study was to investigate the changes in neuronal stem cell proliferation and differentiation during neonatal brain development in BPA-exposed pregnant rats. METHODS: After exposure of BPA to pregnant rats, infant brains were excised at days 3, 7, and 14 after birth, and tissues were processed for histological and biochemical analyses. RESULTS: Proliferating cell nuclear antigen (PCNA) immunostaining showed that whereas cells in the hippocampus at days 3 and 7 after birth were highly proliferating, the cells at day 14 divided less often. Immunohistochemical staining for nestin in the control group revealed that nestin-positive cells were only observed at day 3 after birth, but the immunoreactivity was not observed at day 14. In addition, glial fibrillary acidic protein (GFAP) immunoreactive cells were observed from days 7 to 14 in control tissues. However, in the BPA-exposed groups, 1) the number of PCNA-positive cells in the BPA-exposed groups at days 3 and 7 were higher than those of the control, 2) nestin-positive cells were observed at day 3 which is earlier than that of control, and 3) GFAP-positive cells were detected in the hippocampus tissue from day 3. Furthermore, western blotting showed that exposure to BPA in pregnant rats resulted in earlier expression of nestin in the neuronal rat brain compared to the controls. CONCLUSION: Taken together, it is assumed that precocious neurogenesis in the infant rat hippocampus might be due to BPA exposure during the gestational period. Further studies on adult brain perinatally exposed to BPA are needed to evaluate the pathological status of the hippocampus.

Strumal carcinoid of ovary is an unusual form of monodermal ovarian teratoma with thyroid-like follicles admixed with typical carcinoid tumor pattern. Most of them arise in dermoid cyst or in mature solid teratoma. Recently we experienced a case of strumal carcinoid postoperatively and report this case with a brief review of the concerned literatures.

We report a case of isolated primary medullary hemorrhage with a review of the literature to analyze the clinical presentation and radiological character. A 46-year-old man with chronic alcoholism developed tegmental medullary syndrome secondary to spontaneous hemorrhages in the medulla oblongata. Magnetic resonance imaging study was carried out on the third day after the second event, which showed two distinct isolated hematomas in the medulla oblongata. Digital subtraction angiography was normal. The cause of hemorrhage was presumed to be cryptic vascular malformation. The primary medullary hemorrhage usually presents with a characteristic syndrome of sudden onset vertigo with neurological signs that correspond to various combination of medial and lateral medullary involvement. Usually, the prognosis is good only with conservative treatment.

Fibrolipoma is a rare variant of lipomas which shows distinct pathologic findings with both component of mature adipose cells and broad bands of dense fibrous connective tissue. A 52-year-old woman presented with 2X2cm sized, indurated, slightly elevated and slightly tender subcutaneous mass which slowly enlarged during the last four to five years accompanied by slight tenderness on the right upper back. The laboratory examination showed non-specific findings. Histopathologic findings revealed a well-defined mass composed of eosinophilic dense connective tissue bands with mature adipose cells scattered throughout the mass. The lesion was totally excised and she showed no evidence of recurrence after 6 months of follow-up.

A 30-year-old man presented with several intensely prurutic erythematous serpiginous thread-like skin lesions which began as a small papule on the upper back 2 weeks prior to his visit and was migrating to the lower back and buttock area. The laboratory examination showed non-specific findings. Histopathologic examination revealed a pustular burrow containing numerous eosinophils in the epidermis. In the dermis, there was a diffuse and occasionally dense perivascular inflammatory cell inflammation consisting of eosinophils and some lymphocytes. The patient was treated with oral albendazole, antihistamine and topical corticosteroid for 2 weeks without recurrence for 6 months up to now. Multiple histologic sections were made without success in demonstrating parasitic tissue in the epidermis, however, the clinical and histopathologic features were consistent with cutaneous larva migrans.

PURPOSE:To determine by means of MR imaging the ischemic status of parenchymal lesions in moyamoya disease. MATERIALS AND METHODS: Ninety-two MR images in 50 children with moyamoya disease were retrospectively reviewed. Ischemic parenchymal lesions were categorized according to the signal intensities of cortex and subcortical white matter. We also analyzed enhancement patterns, time sequential changes in the lesions, and the Prognosis for each patient, according to lesion type. RESULTS: Among one hundred and seventeen parenchymal abnormalities, 89 gyral lesions were seen in 43 children (86 %), predominantly in the frontal area (33.1%). Cortical parenchymal lesions were categorized as either type I - intermediate to high signal intensity (SI) on both T2 weighted (T2WI) and proton density images(PDI), and associated with low SI of the subcortical white matter; type II - high SI on T2WI and PDI, without low SI of the subcortical white matter; or type III - high SI on T2WI and iso SI on PDI. Thirty-three lesions were type I, ten were type II, and 43 were type III. Time sequential changes from type I to type II, and then to type III, were observed. The prognoses of patients with a type-I lesion were better than those of patients whose lesions were type II or III. CONCLUSION: Type I lesions presented with abnormal low signal intensity in the subcortical white matter, as seen on T2W1 images. This was the characteristic and earliest finding of ischemic parenchymal lesions in moyamoya disease; sequential MR images showed that type-I lesions progressed to type II or III.

Moyamoya disease(MMD) is defined as the development of collateral anastomosis pathways, associated with bilateral chronic progressive stenosis of the carotid fork. We have reviewed the types of presentation, angiograms, and single photon emission computed tomographs(SPECT). Ninety-nine patients were divided into three groups (aged below 5 years, between 5 and 15 years, and 16 or over) to investigate whether there were differences in clinical presentation and hemodynamic characteristics between the age groups. Mean age of the 99 patients was 13.6 years and the mean duration of symptoms was 26.2 months. In the 17 children aged less than five, the duration of symptoms was shorter(4.8 months) than in older patients(p<0.05). The former presented mostly with cerebral infarction(59%) with a widespread cerebral perfusion defect(50%). Among 56 children who were 5 to 15 years old, 42 (75%) presented with transient ischemic attacks and 10(18%) with cerebral infarction; the latter was less frequent in this age group than in other age groups. Twelve(46%) out of 26 adult patients had hemorrhage at the initial diagnosis, which was the most frequent presentation in this age group. Stenosis of the posterior cerebral artery was detected in 27% of adult MMD patients, while it was detected in 39% of children. Moreover, no case showed widespread perfusion defects in the adult group. The results suggest that the patterns of presentation and the hemodynamic features differ according to the age at which initial major symptoms occur. Children aged less than five suffer rapid progression of the disease and severe cerebral pefusion defect, and should therefore undergo early surgery. The less frequent involvement of MMD in the posterior circulation and better-preserved cerebral perfusion are characteristic findings of the disease in adults, and this seems to account for its delayed onset.
