Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.

BACKGROUND: Bcl-2 protein is essential for neurodevelopment and it is implicated in various neurodegenerative diseases. However, little is known about the normal developmental expression of Bcl-2 and NeuN protein in hippocampus slice cultures. We performed this study to assess their morphological changes and developmental expressions of Bcl-2 and NeuN protein. METHODS: We cultured the hippocampus of an eight days postnatal Sprague-Dawley (SD) rat in slices of 450 m. We observed the morphological development and differentiation of the hippocampus slices. Additionally, we measured the developmental expression of Bcl-2 and NeuN, -actin protein by western blotting. RESULTS: The hippocampal slice cultures revealed matured structures as early as 6 days in vitro (DIV) and a relatively high degree of tissue organization until 18 DIV. After 21 DIV, there were migration of the cells away from the margins of the slices. NeuN expressions at 7, 13, and 19 DIV were 1.42 +/- 0.38 (meanSD, NeuN/ beta-actin OD ratio, insert number=4, each insert had 5 culture slices), 2.95 +/- 0.53, 1.58 +/- 0.42 respectively. Bcl-2 expression at 6, 12, and 18 DIV were 0.56 +/- 0.18 (mean +/- SD, Bcl-2/beta-actin OD ratio, insert number=4, each insert had 5 culture slices), 1.22 +/- 0.28, 1.03 +/- 0.25. CONCLUSIONS: Organotypic slice cultures of a rat's hippocampus shows morphological maturation within 14 DIV and the highest NeuN and Bcl-2 level at about 13 DIV. It is expected that these findings would be useful as baseline data in the field of research on neuronal development and aging processes.

Lateral compartment syndrome of the lower leg is rarely observed. Hence, there may be difficulty in diagnosis as its clinical patterns are different and more complicated than usual. We report two rare cases of a 20-year-old and a 28-year-old diagnosed with isolated lateral compartment syndrome who had either a surgical or conservative treatment. The comparison was done by analyzing the progression of neurological manifestation, electromyography, and nerve conduction study for two years. In the final follow-up, the patient who underwent the surgical treatment showed a shorter recovery time. However, both patients showed a full recovery from neurologic deficits.

BACKGROUND: The interest of patients with chest pain and normal coronary arteries has been increased since 1960. From the year 1973, the syndrome representing these characteristics has been classified as syndrome X. Treadmill test and exercise TI-201 SPECT are important in the diagnosis of syndrome X. This study was designed to evaluate the clinical value of exercise TI-201 SPECT and the difference of clinical characteristics between exercise TI-201 SPECT positive(Group A) and negative (Group B) in patients with chest pain and normal coronary angiogram. METHODS: Twenty seven patients with chest pain and normal coronary angiogram underwent echocardiogram and exercise TI-201 SPECT. Patients received 2 mCi of thallium intravenously during exercise, redistribution images were performed 4 hour later and second dose of 1 mCi of thallium was injected at rest immediately thereafter. These three sets of image(stress, redistribution and reinjection) were analyzed. RESULTS: 1) 12 of 16 patients in Group A, none of 11 patients were positive on exercise treadmill test(p<0.005). 2) The incidence of systemic hypertension in Group A was significant greater than Group B(p<0.05). 3) The left ventricular end diastolic pressure was significantly higher in Group A than in Group B (p<0.05). CONCLUSION: The exercise TI-201 SPECT is a useful method to evaluate the patients with chest pain and normal coronary angiogram and the reversible perfusion defects on the exercise TI-201 SPECT might be related to systemic hypertension and elevated left ventricular end diastolic pressure.

BACKGROUND: The developing brain has a distinctive set of characteristics that make it have different susceptibility to excitotoxins. Using primary tissue cultures of rat hippocampus, we investigated the developmental susceptibility to N-methyl-D-aspartic acid (NMDA)-induced cell death at various days in vitro in relation to the appearance of Bcl-2 protein and NMDA receptor 2B subunit. METHODS: Six, 12, and 18 days-in-vitro (DIV) hippocampal tissue cultures derived from 7-day-old Sprague-Dawley rat pups were used. Each group was treated with 100 micrometer NMDA in 5% CO2 incubator at 36 degrees C for 30 min. A western blot was then performed for the NeuN, Bcl-2 and NMDA receptor 2B subunit and propidium Iodide (PI) staining. RESULTS: The NeuN and Bcl-2 were most highly expressed in 12 DIV tissues. The reductions of the NeuN and Bcl-2 protein expressions by NMDA were significant at the 12 and the 18 DIV tissues, but less at 6 DIV tissues (p<0.05). The PI staining showed that the area of fluorescence of the 7 DIV tissues after NMDA exposure was less than the DIV 13 and 19 tissues. Without NMDA treatment, the NMDA receptor 2B subunit protein expressions at the 6 DIV tissues were highest and decreased with maturation. CONCLUSIONS: These results suggest that the immature tissues were more resistant to NMDA toxicity than the mature tissues, and further studies are needed to establish its relationship with the Bcl-2 protein and NMDA receptor 2B subunit.

Over the last 20 years, the frequency of multiple pregnancy has increased mainly because of the introduction of exogenous pituitary gonadotropins in the treatment of infertility. Since the advent of assisted reproductive technology, the concern about ectopic implantation of embryos has increased dramatically and it continues to be a major complication of in vitro fertilization and embryo transfer (IVF-ET). Bilateral tubal pregnancy is the least common type of ectopic implantation of two embryos. Of all extrauterine pregnancies, 1:725~1:1580 are bilateral1,2. Simultaneous tubal pregnancies have been reported in natural cycles, recently, after ovulation induction, in-vitro fertilization2,3. The high incidence of ectopic pregnancy associated with IVF-ET continues to be a problem and frequencies of between 2.4 and 12.4% have been only a few reports of simultaneous bilateral tubal pregnancies following IVF-ET4. This paper describes a case of a simultaneous bilateral tubal pregnancy after IVF-ET in a 33 year old patient. The diagnosis was confirmed by diagnostic laparoscopy performed 25 days after embryo transfer(sixth week of gestation), which revealed bilateral tubal pregnancy. Bilateral salpingectomy was performed. With a review of the literature on this topic, diagnostic aspects and treatment options are discussed.

Uterine artery embolization was introduced to arrest post-partum hemorrhage 20 years ago. It has also been used to control severe hemorrhage from uterine gestational trophoblast tumors, carcinoma of the uterus, uterine arteriovenous malformations, and cases of pelvic trauma. More recently, transcatheter uterine artery embolization is a new treatment for uterine leiomyoma. A 33-year old married woman with 2 children had a history of heavy pelvic pain and pressure. Ultrasound and MRI investigation showed a bulky 12 x 10cm submucosal myoma in right lower uterine segment. The both uterine artery embolization was performed via a bilateral femoral artery. We present a case in which successful embolization of the uterine arteries in a woman with submucosal myoma resulted in a subsequent transcervical expulsion of large pieces of the dominant fibroid after 3 month of treatment with a brief review.

Shwachman-Diamond syndrome (SDS) is a rare genetic disorder of unknown pathogenesis involving exocrine pancreatic insufficiency and hematological and skeletal abnormalities. About 25% of patients develop hematopoietic malignancies. We report on a case of acute myeloid leukemia (M2) in a 21-year-old woman affected by SDS. She was treated with conventional chemotherapy (idarubicin plus cytarabine) and reached complete remission of leukemia. After induction chemotherapy, she underwent allogeneic bone marrow transplantation (BMT). The BMT preparative regimen consisted of total body irradation (TBI) followed by cyclophosphamide. Cyclosporin A and short term methotrexate were used for graft-versus-host disease prophylaxis. After a follow-up of 12 months, she is alive leukemia free off any immunosuppressive agent. Although experience in this field is scarce, we speculate that bone marrow failure in SDS is an indication for BMT which is the only curative trentment option.
