Cheilitis granulomatosa is one of the rare dermatoses which is characterized by a sudden onset and a progressive course termination in chronic enlargement of the lips Usually, enlargement of lip is the only symtom without ulceration, fissurign or scaling. It may be considered a part of the Melkersson-Rosenthal syndrome and the etiology is still unknown. A 35 year old female with the clinlcal symptoms of cheilitis granulomatosa is presented; the diagnosis was confirmed by histopathologic study.

BACKGROUND: There have been only a few electron microscopic studies after laser treatment of pigmented skin lesions. OBJECTIVE: The purpose was to investigate the pathologic, immunohistochemical, and electron microscopic changes following Q-switched alexandrite laser treatment of pigmented skin lesions. METHODS: Three patients with acquired bilateral nevus of Ota-like macules, and 2 patients with cafeau lait macule were irradiated with Q-switched alexandrite laser. Forty biopsies were taken before and immediately after laser treatment. Hematoxylin-eosin, Fontana-Masson, and gp100 staining were performed for the evaluation of the histopathologic and immunohistochemical findings of the specimens. Electron microscopic findings were also evaluated. RESULTS: Histopathologically, suprabasilar separations were observed immediately after laser treatment. Vacuolar alterations of pigment-containing cells were frequently found in the epidermis and/or in the dermis. Fontana-Masson and gp100 staining positivity changed to negative or decreased in the epidermis immediately after laser treatment, while they changed to negative in the dermis. Ultrastructurally, epidermal pigment-containing cells frequently showed severe vacuolar changes in the cytoplasm, pyknotic nuclei, and vacuolated and/or fragmented melanosomes immediately after laser treatment. Dermal melanocytes frequently revealed vacuolated and/or fragmented melanosomes immediately after laser treatment. CONCLUSION: Histopathologic, immunohistochemical, and electron microscopic examination of pigmented skin lesions immediately after Q-switched alexandrite laser treatment demonstrated vacuolated or fragmented melanosomes and vacuolar alteration of pigment-containing cells in the epidermis and/or in the dermis, which suggested selective photothermolysis of melanosomes.

INTRODUCTION: The pathophysiology of PIH remains unclear. Recently, placental abnormalitiesare stressed as a possible cause of PIH. Abnormal shallow invasion of trophoblasts, confinedto decidua, without involving myometrium is believed to result in reduced uteroplacentalperfusion, endothelial injury, and activation of coagulation cascade system. Integrin, one of theadhesive membrane proteins, is expected to be related to the regulation of trophoblasts invasion. PURPOSE: The purpose of this study is to investigate the expression of adhesion moleculesin placenta and the correlation between uterine artery Doppler findings and integrinexpressions in the placentas of PIH patients. SUBJECTS: Thirty-six cases of severe PIH patients were enrolled in the study with 10number of normal control pregnant women. The integrin subunit expressions withimmunohistochemical staining were observed in floating villi, maternal-side cytotropholbasts, andfetal-side cytotrophoblasts. Uterine artery Doppler study was also performed, and the S/Dratio was evaluated. Abnormal Doppler findings was defined as S/D ratio>or=2.6. RESULTS: Cytoplasmic staining of villi and placental bed cytotrophoblast for theintegrin alpha1 subunit in PIH specimen was weaker than those in normal controls. Theexpression of integrin beta1 subunit was negative for both controls and PIH group. Thepositive cytoplasmic stain was observed among PIH placenta in contrast to normal control inwhich the expression of integrin beta4 subunit was not detected. The expression of alpha v beta3 introphoblast with PIH was positive staining, but not in control group. Uterine artery Dopplervelocimetry was performed in 25 cases with PIH. Trace(+/-) or - staining of integrin alpha1 subunit were observed in 60.0% of abnormal S/D(>or=2.6) group, 20.0% of normal S/Dratio group patients, respectively. Trace or + staining of integrin beta4 subunit were observedin 50.0% of abnormal S/D group and 6.7% of normal S/D group and this is in statisticallysignificant. Trace or + staining of integrin alpha v beta3 subunit were observed 70.0% ofabnormal S/D group and 26.7% of normal S/D group, and this statistically significant. CONCLUSION: In PIH the abnormality in the invasion of cytotrophoblats results inabnormal integrin subunit expression, but it is also correlated to the abnormal uterine arteryDoppler velocimetry which shows a S/D ratio of greater than 2.6. Thus, the uterine arteryDoppler velocimetry reflects abnormal placentation.

Seborrheic keratosis, a benign tumor is more common in the elderly and composed of epidermal keratinocytes. Seborrheric keratoses are very common in white races and are often of little concern to the patient, being accepted as a harmless and inevitable consequence of aging. This tumor was classified into six histopathological types by Lever; acanthotic, hyperkeratotic, adenoid, irritated, clonal, and melanoacanthoma. In 1978 Tagami and Yamada reported a rare acantholytic variant of seborrheic keratosis. We are reporting a case with seborrheic keratosis showing focal acantholysis.

Torsion of the fallopian tube is an uncommon cause for acute low abdominal pain in female that is difficult to diagnose. Because it has no pathognomonic clinical symptoms or laboratory findings, a high index of suspicion is important when there is history of pelvic pathologic conditions or surgery. The early diagnosis and surgical treatment of the disease are mandatory to preserve oviduct.

Certain angiographic patterns outlining the morphologic characteristics of vessels and defining the lesion-specific characteristics have recently been shown to greatly influence the likelihood of a successful dilation. In 1988, ACC/AHA Subcommitte on percutaneous transluminal coronary angioplasty proposed the lesion-specific classification as a guide for estimating the likelihood of a successful procedure as well as the the likelihood of developing abrupt vessel closure. To determine the lesion-specific predictors for successful dilation and complications after percutaneous transluminal coronary angioplasty, nine angiographic charateristics of 200 lesions in 164 patients who underwent coronary angiplasty between May, 1983 and September, 1989 were analyzed. 1) Successful dilation, defined as a reduction in stenosis diameter to less than 50% without acute myocardial infarction or emergency coronary artery bypass graft, occurred in 175 of 212 lesions(82.5%). 2) Successful dilation occurred in 13 of 15 type A lesions(86.6%), 148 of 178 type B lesions(83.1%) and 3 of 7 type C lesions(42.8%)(p<0.05 for A or B vs C). 3) Acute closure syndrome occurred in none of type A lesions, 6 of type B lesions(3.4%), 2 of type C lesions(28.5%)(p<0.005 for A or B vs C). 4) multivariate analysis showed that lesion-specific characteristic predictors for successful dilation were length of lesion(p<0.05) and accessibility(p<0.05) ; for ischemic events were major branch involvement(p<0.05) and eccentricity(p<0.05); for acute closure syndrome were accessibility(p<0.05) and eccentricity(p<0.05). 5) Procedural predictors for ischemic events were coronary artery dissection(p<0.01), post-PTCA diameter stenosis(p<0.05) and balloon/artery diameter ratio(p<0.01) ; For acute closure syndrome was coronary artery dissection(p<0.005). In this analysis, we found that angiographic lesion-specific characteristics related very importantly to procedural success and were able to define three major independent lesionspecific risk factors whose presence beforehand decreased the likelihood of successful dilation and increased the likelihood of acute closure. In the absence of any of these risk factors, the risk of acute closure is very small. Thus, identification of these factors and their associate risk should improve patients selection and better define the role of coronary angioplasty in the management fo patients with coronary artery disease.

Vitiligo is an acquired, progressive depigmenting disorder of unknown etiology. In this study, to clarify pathogenesis of vitiligo, the marginal skin of actively spreading and stable vitiligo was examined using ICAM-1, HLA-DR, CD4 and CD8 monoclonal antibodies. In immunohistochemical study, ICAM-1 was expressed in four of five epidermis in active lesions, but not in stable lesion. Dermal ICAM-1 was also expressed in all active and stable lesions. HLA-DR was also expressed in all active epidermis in active lesions, but two of five epidermis in stable lesion. Dermal HLA-DR was also expressed in all active and stable lesion. CD4 lymphocytes were expressed more strongly in active lesion, but CD8 lymphocytes were not different in both lesions. There was no significant difference of degree of positivity with CD4 and CD8 in normal control specimens. In conclusion, we think that ICAM-1 and HLA-DR expression, cytokines released from keratinocytes, melanocytes or lymphocytes and infiltration of activated T-lymphocytes play an important role in disease activity.

PURPOSE: To compare the usefulness of echo-planar imaging (EPI) and fast spin-echo (FSE) in routine brain MR imaging. MATERIALS AND METHODS: Twenty-five patients with various intracranial diseases were prospectively examined with T2-weighted MR imaging on a 1.5T unit using FSE, spin echo singl-shot EPI (SS-EPI) and multi-shot EPI (MS-EPI) techniques. For qualitative assessment, overall image quality, discrimination between cortical gray-white matter and between basal ganglia-white matter, lesion conspicuity, image distortion and artifacts (motion, ghost, flow, and susceptibility) were all evaluated using a subjective scoring system ranging from 1 to 4 (1 for the worst and 4 for the best). For quantitative assessment, contrast and contrast-to-noise ratio (CNR) were calculated for cortical gray-white matter, basal ganglia-white matter, and lesion-white matter. RESULTS: Overall image quality, discrimination between cortical gray-white matter, basal ganglia-white matter, and lesion-white matter, lesion conspicuity, image distortion and susceptibility artifacts showed the highest value in FSE and the lowest in SS-EPI. Motion artifacts were seen only in FSE, while flow and ghost artifacts were most commonly seen in SS-EPI. Contrast and CNR of anatomical and pathologic structures showed the highest value in FSE, especially for cortical gray-white matter and basal ganglia-white matter . CONCLUSION: With regard to overall image quality, image distortion, susceptibility artifacts, contrast and CNR, EPI is far inferior to FSE. In routine brain MR imaging., the usefulness of EPI techniques would therefore be very limited.

The purpose of the present study was to investigate the effect of ethanol extracts from red pepper seeds on the antioxidative defense system and oxidative stress in rats fed a high fat . high cholesterol diet. Rats were divided into four experimental groups which were composed of high fat . high cholesterol diet group (HF), high fat . high cholesterol diet with 0.1% ethanol extracts from red pepper seeds supplemented group (HEA), high fat . high cholesterol diet with 0.2% ethanol extracts from red pepper seeds supplemented group (HEB) and high fat.high cholesterol diet with 0.5% ethanol extracts from red pepper seeds supplemented group (HEC). Supplementation of ethanol extracts from red pepper seeds groups (HEA, HEB and HEC) resulted in significantly increased activities of hepatic glutathione peroxidase and catalase. Hepatic superoxide radical contents in microsome and mitochondria were significantly reduced in the groups supplemented with red pepper seeds ethanol extracts. Hepatic hydrogen peroxide content in the mitochondria was reduced in ethanol extracts from red pepper seeds supplemented groups. TBARS values in the liver were reduced in red pepper seeds ethanol extracts supplemented groups. Especially, HEB and HEC groups were significantly decreased compared to the HF group. Hepatic carbonyl values were significantly reduced in mitochondria in these supplemented groups. These results suggest that red pepper seeds ethanol extracts may reduce oxidative damage, by activation of antioxidative defense system in rats fed high fat . high cholesterol diets.
