Split hand split foot(SHSF) is a rare human developmental defect characterized by mi-ssing digits, fusion of remaining digits, and a deep median cleft in the hands and feet. Cy-togenetic studies of deletions and translocations associated with this disorder have indicated that an autosomal dominant split hand/split foot locus maps to 7q21-q22. We have experienced a case of ectrodactyly in a 25-year-old primigravida woman and her baby and reported out our experience with a review of related literature.

We examined effects of interleukin 1 alpha (IL1 alpha) and phorbol 12, 13 dibutyrate (PDB), an activator of protein kinase C, on mRNA for Prostaglandin H synthase (PGHS) and prostanoid production in cultured ovine meningeal fibroblasts. Immuno- and morphologically-identified fibroblasts were derived from cerebral cortex and white matter from fetal lambs (approximately 120 days gestation) and grown to confluence on glass coverslips in 12 well plates. Levels of prostaglandin F2alpha and the stable hydrolysis product of prostacyclin (i.e., 6-keto-PGF1alpha) were determined using enzyme immunoassay. Relative amounts of mRNA were determined by in situ hybridization using ovine cDNA for PGHS1. IL1alpha (10 ng/ml) increased mRNA levels over baseline by 62 +/- 19% (p<0.05) at 60 min., 37 +/- 12% (NS) at 120 min., and 36 +/- 18 % (NS) at 240 min (n= 12). Levels of 6-keto-PGF1alpha were 148 +/- 18 pg/ml during baseline, 246 +/- 41 pg/ml at 60 min., 248 +/- 40 pg/ml at 120 min., and 259 +/- 62 pg/ml at 240 min (all p<0.05) (n=12). PGF2alpha was increased although it wasn't statistically significant. However, IL1alpha decreased PGE2 level significantly (all p<0.05). PDB (10-6 M) increased mRNA levels over baseline by 25+/-6% after 30 min., 40 +/- 6% after 60 min., and 20 +/- 8% after 90 min. (n=9) (all p<0.05). Levels of 6-keto-PGF1alpha were 200 +/- 43 pg/ml during baseline, 202 +/- 43 pg/ml after 30 min. (NS), 268 +/- 58 pg/ml after 60 min. (p<0.05), and 296 +/- 60 pg/ml after 90 min. (p<0.05) (n=9). Levels of PGF2alpha were 178 +/- 26 pg/ml during baseline, 300 +/- 30 pg/ml after 30 min., 299 +/- 35 pg/ml after 60 min., and 355 +/- 32 pg/ml after 90 min (all p <0.05) (n=6). Actinomycin-D (1 mg/ml) prevented increases in mRNA, 6-keto-PGF1alpha, and PGF2alpha at 60 min. for both I-L1 alpha and PDB. We conclude that cerebral fibroblasts are avid producers of prostanoids, and that enhanced production of PGHS is responsible for augmented PGF2alpha and prostacyclin production in the presence of an activator of protein kinase C and for decreased PGE2 and increased prostacyclin production in the presence of IL1alpha.

Bone involvement is a common finding in many types of lymphomas, particularly in advanced stages. However, cranial vault affliction has been regarded as an exceedingly rare presentation. Here, we report the case of a patient with cranial vault lymphoma who presented with a scalp mass. An 81-year-old woman presented with a gradually growing and non-painful frontal scalp mass that she noticed one month before admission. It was a flatly elevated, round mass measuring about 6x4x4 cm. Computed tomography and magnetic resonance imaging of the brain revealed a contrast-enhancing intracranial extradural mass at the counter-location of the scalp mass. The superior sagittal sinus was involved at the tumor site. Cerebral angiography showed that the tumor feeding vessels originated from the bilateral external carotid arteries. An operation was performed and the tumors were removed together with the involved bone. The pathologic diagnosis was malignant diffuse large B-cell type lymphoma. The patient was transferred to the Hemato-Oncology department for chemotherapy. Primary lymphoma of the cranial vault with scalp mass is very rare but it should be considered in the differential diagnosis of scalp masses. Although the results of reported cases are variable, the combination of surgery, radiation, and chemotherapy appears to offer favorable outcomes.

Multiple primary or secondary malignancies after anticancer therapy were recently reported to be increasing in frequency. The authors describe a case of metachronous metastatic pulmonary basaloid carcinoma to the central nervous system that was discovered after chemotherapy and radiation therapy for cervical uterine carcinoma. Two different types of cancer developed within some interval. There's the possibility that a secondary pulmonary neoplasm developed after the chemotherapy and radiotherapy conducted as cervical cancer treatment.

Polycythemia is a condition in which the red blood cell count is increased due to an inherited or acquired mutation, a physiologic response to hypoxia, autonomous erythropoietin production, or deliberate erythropoietin administration. Higher testosterone levels appear to act as a stimulus for erythropoiesis and testosterone replacement therapies have rarely been reported as causes of polycythemia. We report here a case of a 51-year-old man with polycythemia that was caused by long-acting testosterone undecanoate (Nebido(R)).

BACKGROUND AND OBJECTIVES: Mechanisms of restenosis following successful coronary angioplasty (PTCA) are knownasvascularsmoothmuscle cells(VSMCs)proliferationandmigration, elastic recoil or vascular wall remodeling. Paclitaxel whose effect on the stabilization of microtubles leads to cell death is highly lipophilic, permitting easy pass through cell membrane, and has a long-term antiproliferative effect. This study was performed to evaluate effect of paclitaxel on VSMCs proliferation and whether locally delivered paclitaxel can prevent stenosis and neointimal formation in rat carotid artery injury model. MATERIALS AND METHODS: Cultured VSMCs were exposed to sequential concentrations of paclitaxel in vitro, and proliferation inhibition was analyzed with 3H-thymidine incorporation. Paclitaxel of a suitable concentration was applied to the endothelium-denuded carotid artery of Fisher 344 inbred rats for 20 minutes. Angiogram and morphometric analysis of carotid artery was performed after 2 weeks. RESULTS: 3H-thymidine incorporation in cultured VSMCs was decreased dose-dependently from the concentration of 0.1 micromol/L (2,454+/-149cpm/ microgram protein) to 100 micromol/L (1,323+/-69cpm/ microgram protein) of paclitaxel by single and 20-minute exposure in the presence of platelet-derived growth factor (p<0.005). In the absence of platelet-derived growth factor, the decrement of 3H-thymidine incorporation was evident above the concentration of 5 micromol/L of paclitaxel. To evaluate in vivo effect, paclitaxel (0.1 or 1 micromol/L) was administered into the endothelium-denuded carotid artery by balloon injury and incubated for 20 minutes. Percent stenoses (32.2+/-9.8%) of paclitaxel-treated group was less than those (46.3+/-7.5%) of control group on histologic analysis (p<0.01). Paclitaxel-treated group also had wider lumen on carotid angiogram and less neointimal thickening than control on histologic examination (p<0.005). CONCLUSION: Proliferation of VSMCs was effectively inhibited and neointimal formation and luminal stenosis was prevented in rat carotid artery injury model by single, brief and local delivery of low-dose paclitaxel. This strategy could be applied to clinical settings for the prevention of restenosis after PTCA.

Korean Journal of Medicine 1998;55(6):1031-1038
OBJECTIVES: Few disciplines in medicine encompasses such wide diagnostic and treatment modalities as cardiology. A traditional text and education system is limited in its efficacy to convey such variety. In order to address this problem, a comprehensive computer-aided education system that compiles and links the current knowledge of cardiovascular diseases is proposed. An availability of such system through CD-ROM and world wide web will contribute undoubtedly to the promotion and betterment of current understandings of cardiology all over the world. METHODS AND RESULTS:1) The information about the cardiovascular diseases has been complied and organized. Multimedia medical information includes text, audio features that allow the users to study actual sounds, and visual aids (slides, real-time demonstration, and schematic illustrations).2) Cardiology education system can be approached according to "Disease module" or "Laboratory test module". One can readily look up the disease of interest and see the results of different tests. Or one can choose the laboratory test or physical examination and study the differences among the diseases. "Self test module" is also available to help user's self assessment of his/her understanding of cardiovascular diseases.3) This cardiology education program is conveniently stored in CD-ROM and can also be accessible through the world wide web (http://med.chungbuk.ac.kr/~mccho/ web-cardiology/alogo.html). CONCLUSION: A multimedia approach for the study of cardiovascular diseases has been developed and is now avaliable in CD-ROM. The same information can be obtained from our home page through the world wide web.

The purpose of this study was to investigate the differences in MR findings of adenocarcinoma (AC) and squamous cell carcinoma (SCC) of the uterine cervix and to compare MR findings with pathologic findings. MR images of 17 patients with pathologically proven AC, using a fast spin-echo (FSE) T2-weighted image (T2WI) with pelvic phased-array coil on a 1.5-T unit, were retrospectively evaluated. After measurement of the signal intensity (SI) ratios of the region of interest between tumors and gluteus maximus muscle, we compared the ratios of AC with those of 16 patients with SCC. AC showed relatively high SI on FSE T2WI with multiseptated lesions in four cases and hydrometrocolpos in three cases. The mean SI ratio was 3.82 +/- 1.68 in AC and 2.35 +/- 0.42 in SCC (p < 0.0001, t-test). Multiple tumorous glands with cytoplasmic and intraglandular mucin or serous fluid were pathologically found in AC, but SCC revealed the compact cellularity of stratified squamous tumor cells. The cervical AC showed higher SI than SCC on FSE T2WI with occasional multiseptated lesions and hydrometrocolpos. If the SI ratio of the tumor was more than 3.0, AC could be diagnosed with a sensitivity of 68.8% and a specificity of 100%.
