It has been generally assum d that eccrine poroma arises from acrosyringium, the epidermal sweat duct unit. Eccrine poroma mainly involves the non hairy surfaces of the skin, but it has also been found on hair-bearing areas. One of the characteristics of this structure is absence of melanocytes and melanin granules arnong its cells. However a complete absence of melanocytes and melanin granules in eccrine poroma is not invariable and a few reports of such an occurrence have been presented. The authors report herein a case of unusual and rare eccrine poroma. The eccrine poroma had melanin pigment and melanocytes, was pedunculated and occurred on the parietal scalp which was the unusual site of involvement. The eccrine poroma was also combined with a pedunculated congenital melanocytic nevus on the supraauricular scalp.

Necrolytic migratory erythema is a rare, distinctive, necrotizing cutaneous eruption usually associated with glucagonoma, an alpha-cell tumor of the pancreas. Other clinical features include ane- mia, diabetes mellitus and weight loss. However, it also occurrs without the pancreatic glucagonoma. So this rare condition is called pseudoglucagonoma syndrome, and has been described in association with chronic hepatic diseases, malabsorption with villous atrophy, chronic pancreatitis, celiac sprue, hypoproteinemia and odontogenic infection. We report a case of pseudoglucagonoma syndrome induced by malnutrition without glucagonoma. A 28-year-old Korean female was referred to our department complaining of multiple erythematous, desquamative, crusted and erosive patches on the extremities, and diffuse scalp alopecia for 5 years. She also had perianal erosion, angular cheilitis without glossitis, amenorrhea, axillary and pubic hair loss, and weight loss. Six years previously she had had Whipples operation for a pancreatic solid and papillary neoplasm. The laboratory data showed hypoalbuminemia, essential fatty acid deficiency, diabetes mellitus and slightly high levels of zinc and glucagon. A skin biopsy showed irregular acanthosis, epidermal edema and pallor, dyskeratosis, areas of superficial epidermal necrosis and vascular dilatation of the papillary dermis. The patient improved dramatically after intravenous hyperalimentation and oral intake of mediurn chain triglyceride. For 2.5 years she has taken medium-chain triglycerides without any other treatment, and no side effects on recurrence has been observed.

Anal gland/duct cyst (AGC) is rare and observed in only 0.05% of patients undergoing anal surgery. AGC is thought to be a retention cyst in the anal gland and arises when an obstruction of the anal duct causes fluid collection in the anal gland. We report a case of AGC in a 66-year-old woman without anal symptoms. Found by colonoscopy, the AGC was excised transanally. The histopathology of the specimen confirmed AGC. Colonoscopists should include AGC in the differential diagnosis of anal canal mass and rule out of malignancy. Excision is recommended for definitive diagnosis and treatment.

This study was carried out to research the adaptation patterns of head posture after activator therapy in functional class ill malocclusion patients. For this purpose, 29 functional class III malocclusion patients, from the ages of 8 to 13 years old, were used. 1. Increase in capacity of oral cavity capacity were found in all the samples, but craniocervical angulation were varied into increased group and decreased group after activator therapy. 2. Head posture exhibited the compensatory adaptation in the relative growth increments of the vertical dimension, ALFH and PLFH. 1) A group with more PLFH and less sagittal angle showed relatively small growth increment in PLFH during the treatment period, thus craniocervical angulation was increased. 2) A group with less PLFH and more sagittal angle showed relatively great growth incrmenet in PLFH during the treatment period, thus craniocervical angulation was decreased.

Angiographic findings were analysed in 22 cases of coronary occlusive disease which were selected from 50 cases of coronary arteriographies done in Department of Radiology, Seoul National Un iversity Hospital from September, 1981 to August, 1984. There were 16 cases of single vessel disease, in which 12 were LAD involvement and 4 were RCA involvement, 2 cases of two vessel and 4 cases of three vessel disease. Site, degree and extent of stenotic involvement in those occlusive coronary diseases were anal ysed with review of literature for selective coronaryarteriography. Since coronary arteriography is the final and accurate examination for the evaluation of occlusive coronary arterial disease, it is expected to be widely used for the diagnosis of occlusive coronary arterial disease which is rapidly increasing recently in this country.

PURPOSE: Grape seed-derived polyphenols (GSPs) provide a concentrated source of polyphenols having antioxidant capacity. In this study we investigated the cytoprotective effect of GSP against oxidative stress-induced cell damage in cultured human retinal pigment epithelial (RPE) cells. METHODS: Cultured adult retinal pigment epithelium (ARPE)-19 cells were incubated with GSP from Vitis vinifera (0.1, 0.5, 1, 5 or 10 microg/mL) for 24 hours and treated with hydrogen peroxide (H2O2, 0.4 mM) for 24 hours to induce oxidative stress. Cell viability was measured using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Intracellular reactive oxygen species (ROS) was quantified using 2',7'-dichlorofluorescein diacetate (DCF-DA) fluorescence. RESULTS: The percentage of viable RPE cells was significantly lower in cultures treated with H2O2 0.4 mM than in control cultures. GSP significantly reduced H2O2-induced cell death in a dose dependent manner. GSP at 0.1, 0.5, 1, 5 and 10 microg/mL significantly reduced cell mortality due to the treatment with H2O2. Intracellular ROS production increased significantly in cultures treated with H2O2 0.4 mM compared with control. There was a significant dose-dependent decrease in intracellular ROS levels after treatment of RPE with GSP. CONCLUSIONS: GSP, a natural polyphenolic compound, can protect RPE cells from H2O2-induced oxidative stress and reduce intracellular ROS production by scavenging free radicals. This suggests potential effects of polyphenolic compounds against retinal diseases associated with oxidative stress.

PURPOSE: To evaluate the effects of macular ischemia and early treatment on the visual outcomes of patients with branch retinal vein occlusion (BRVO). METHODS: This study retrospectively reviewed the records of 42 patients who were treated with an intravitreal bevacizumab injection for BRVO, repeated 3 times at 6-week intervals and were whose data available for a follow-up period of at least 4 years. Best-corrected visual acuity (BCVA) and optical coherence tomography (OCT) results before treatment and at 6, 12, 24, 36 and 48 months after the 3 serial injections, were measured. We assessed macular ischemia, time to the first treatment, and the relationship of these with BCVA. RESULTS: Mean BCVA (log MAR) was significantly improved from 0.67 +/- 0.43 at baseline to 0.30 +/- 0.30 at 48 months (p < 0.001). Four years after treatment, mean BCVA in the macular non-ischemic group was better than in the ischemic group, but this relationship did not hold for mean change in BCVA. There was a statistically significant (p < 0.05) difference between the early (< or =6 weeks) and late (>6 weeks) treatment groups in BCVA and mean change in BCVA after 48 months. There was statistically significant (p < 0.05) difference between the early (< or =6 weeks) and late (>6 weeks) treatment groups with macular ischemia in BCVA after 48 months. CONCLUSIONS: In patients with BRVO, a significant visual improvement was maintained after intravitreal bevacizumab injections, despite the presence of macular ischemia. Early treatment (within 6 weeks) is more effective for maintaining and improving visual acuity. Similar results in the macular ischemia group confirmed the importance of early treatment.
