OBJECTIVE: To evaluate the results of second-trimester maternal serum triple-marker screening test for Down syndrome and open neural tube defects in singleton pregnancies conceived from in vitro fertilization, the screen positive rates and triple-marker level of patients conceiving singleton pregnancies by IVF were compared to those of pregnancies conceived naturally. METHODS: Two hundred singleton pregnancies conceived by IVF and naturally conceived pregnancies who had done maternal serum screening test during the second trimester were analyzed from January 1995 to April 1998. RESULTS: One (0.5%) of the 200 cases of IVF singleton pregnancies had a positive result for Down syndrome compared with 1% of screen positive rate in the 200 cases of naturally conceived pregnancies. The median level of the triple markers were 0.92 multiples of the median(MoM) for alpha-fetoprotein(AFP), 1.44 MoM for unconjugated estriol(E3) and 0.87 MoM for human chorionic gonadotropin(hCG) respectively. CONCLUSION: The positive rate of triple test for Down syndrome and open neural tube defect in the two groups were significantly not different. As additional data are collected, corrected standards should be determined.

BACKGROUND: The epidermal permeability barrier necessary for terrestrial life resides in the intercellular spaces of the stratum corneum and is composed of lipids. OBJECTIVE: Since strrtum corneum lipid may be important for the permeability barrier, we studied the differences and effects of experimentally altered barrier function using acetone and tape-stripping technique. METHODS: The permeability barrier of hairless mouse was disrupted by tape-stripping and acetone treatment and the recovery rate was assessed by histochemical staining, electron microscopic examination and lipid analysis. RESULTS: Although the transepidermal water loss recovered completely by 48 hours in both of the acute models, acetone treated samples seem to have on over-all better recovery rate than tape-stripped samples. The return of barrier function to normal in both tape-stripped and acetone-treated skin was accompanied by a comparable return of normal nile red and ruthenium tetroxide staining. The amount of lipid in stratum corneum paralleled both the return of barrier function towards normal and the extent of prior damage to the barrier in acetone treated skin, yet, the lipid synthesis in tape-stripped skin showed a slower return of lipid content. CONCLUSION: The difference in the recovery rate of the two acute models may be due to the fact that acetone mainly extracts intercellular lipids, whereas, tape-stripping has a prolonged effect by removal of comeocyte in addition to the intercellular lipids. This shows the importance of comeocytes as well as the intercellular lipid bilayer in the recovery of normal barrier function.

3.Pulmonary coccidioidomycosis Diagnosed in an Immigrant.

Coccidioidomycosis is a common infectious disease in southwestern North America, which is caused by the soil fungus, Coccidioides immitis. Due to the mobility of the modern population, increasing numbers of cases are being diagnosed outside the endemic areas. Moreover, diagnosis in non-endenmic areas may be delayed or confused due to its rarity. Here we report a case of pulmonary coccidioidomycisis in an immigrant. The patient presented with unexplained pulmonary symptoms. A history of recent travel to or immigration from an endemic area may suggest coccidioidomycosis. In addition an early tissue biopsy is helpful in establishing this diagnosis.

A 25-year-old woman developed generalized urticaria and an anaphylactic syndrome of sudden onset while she was being treated for her decubitus ulcer with chlorhexidine antiseptic solution. Prick test with 0.5% chlorhexidine produced a wheal in a few minutes. A passive intradermal transfer test (PK test) to her mother was positive. These enabled us diagnose her as having an immunologic contact urticaria to chlorhexidine.

Successful percutaneous transluminal angioplasty (PTA) of an internal mammary artery graft was performed in a 40 year old male patient who had recurrent angina soon after bypass surgery. Coronary angiography showed total occlusion of proximal portion of the left anterior descending artery and normal right coronary artery. Angiography of the left internal mammary artery graft revealed a tight stenosis (90% diameter narrowing) in the mammary artery at its insection into the left anterior descending artery.Angiography after the angioplasty demonstrated a widely patent graft (residual stenosis 10%) and translesional pressure gradient was 10 mmHg.

Epidermal cyst in the fibroadenoma of the breast is very rare. A 29-year-old woman presented with a lump in the upper outer quadrant of the right breast. Clinically it was a fibroadenoma and the excisional specimen showed an encapsulated, firm lobulated lesion with a cystic area on cut surface. The cystic area showed squamous metaplasia of the ductal epithelium and keratinous cyst formation in the fibroadenoma. We report this unusual case with review of literatures.

This study was undertaken to elucidate any quantitative abnormalities of Tlymphocyte subsets (helper/inducer T cell; T cell and suppressor/cytotoxic T cell: T cell) and IgE levels in the peripheraI blood in atopic dermatitis patients by using monoclonal antibodies and enzyme immunoassay, respectively. In addition we have tried to ascertain whether there are any correlations betveen such immuiiologic abnormalities and the severity of the disease. The results showed that there were significant decrease in the mean percentage of T Cells and increase in the mean value of T/T cell ratios in patients with atopic dermatitis. These changes seem to relate to the severity of the disease when evaluated as groups. A significant increase in the mean value of serum IgE was found in atopic dermatitis patients and the change was related to the severity of the disease. But increase of serum IgE level did not correlated closely with the T cell abnormalities in each patients.

Generalized lipodyst,rophy is characterized by generalized loss of body fat, and is asociated vith metabolic ahnormalities, including insulin resistance, hyperglycemia., and hypertriglyceridemia. like acanthosis nigricans, generalized lipodystrophy is a cutaneous marker of insulin re.istant diabetes. We report. herein a twenty year old female witti both classic generalized lipodystripin and acanthosis nigricans, in association with insulin resistant diabetes.

A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy
