Heterotopic pregnancy, simultaneous intrauterine and extrauterine pregnancy, is an extremely rare case. The incidence of heterotopic pregnancy was about 1 to 30,000 pregnancies, but it has increased after wider use of assisted reproductive technology. The rising incidence presents a serious problem as the diagnosis of this potentially fatal condition is often missed. Careful pelvic examination combined with serial beta-hCG determinations, and transvaginal sonography to evaluate the adnexal region are necessary prerequisites for early diagnosis. We report a case of heterotopic pregnancy following in vitro fertilization and embryo transfer(IVF-ET) with a brief review of literature.

Although dural arteriovenous malformations(DAVM) involving the occipital lobe can be the cause of variable posi-tive visual phenomena, the mechanism of these visual disturbances is not fully understood. We report a 42-year-old man with a left occipital DAVM presenting headache and positive visual phenomena in the right hemianopic field. Occipital DAVM was not accompanied by parenchymal lesions in a brain magnetic resonance imaging. The cerebral angiography demonstrated the retrograde flow into the dilated occipital cortical veins as well as the left occipital DAVM having multiple arterial feeders and the drainage into the left transverse sinus. All clinical symptoms disap-peared after a transarterial embolization. Brain 99mTc-ECD single photon emission computed tomography also showed the improvement of hypoperfusion on the left occipital area after the embolization. We believe that the venous hyper-tension by occipital DAVM impeding the perfusion to the occipital lobe plays an important role in producing positive visual phenomena on the hemianopic field.

Hidroacanthoma simplex is a benign tumor believed to arise from the uppermost segment of the intradermal eccrine duct and the acrosyringium, and histologically shows intraepidermal focal growth. A malignant counterpart to this tumor is rare and named malignant hidroacanthoma simplex or porocarcinoma in situ. We report a case of atypical hidroacanthoma simplex, which is considered to be a malignant transformation of benign hidroacanthoma simplex in a 83- year-old female.

OBJECTIVE: The purpose of this study was to evaluate the different patterns of bone loss between the lumbar spine and the femur after ovariectomy in rats. METHODS: Twenty-four female Sprague-Dawley rats underwent a sham operation (the sham group) or bilateral ovariectomy (the ovariectomized group). Four and eight weeks after operation, six rats from each of the two groups were euthanized. Serum biochemical markers of bone turnover including osteocalcin and alkaline phosphatase (ALP), which are sensitive biochemical markers of bone formation, and the telopeptide fragment of type I collagen C-terminus (CTX), which is a sensitive biochemical marker of bone resorption, were analyzed. Bone histomorphometric parameters of the 4th lumbar vertebrae and femur were determined by micro-computed tomography. RESULTS: Ovariectomized rats were found to have higher osteocalcin, ALP and CTX levels than sham controls. Additionally, 8 weeks after ovariectomy in the OVX group, serum levels of osteocalcin, ALP and CTX were significantly higher than those of 4 weeks after ovariectomy. Bone loss after ovariectomy was more extensive in the 4th lumbar spine compared to the femur. Bone loss in the 4th lumbar spine was mainly caused by trabecular thinning, but in the femur, it was mainly caused by trabecular elimination. CONCLUSION: The present study demonstrates different patterns of bone loss between the 4th lumbar spine and the femur in ovariectomized rats. Therefore, when considering animal models of osteoporosis, it is important that bone sites should be taken into account.
