Apocrine hidrocystoma is an uncommon benign tumor derived from the secretory segment of apocrine sweat glands and another name for it is apocrine cystadenoma. A 48-year-old female patient had a solitary, translucent red-brownish cystic nodule, 10 × 6 × 7mm in size, on the periorbital area of her left eye. The lesion had enlarged very slowly for 25 years. We excised the lesion and identified it as apocrine hidrocystoma. This is a case of apocrine hidrocystoma with typical clinical and histopathological findings.

BACKGROUND: Laser resurfacing has beneficial effects for the treatment of several skin conditions. Recently, the pulsed erbium:YAG laser has been shown to be a highly effective treatment for several kinds of pitted facial scars. OBJECTIVE: The purpose of this study was to assess the efficacy and safety of pulsed erbium:YAG laser skin resurfacing at the setting of low or high energy for pitted acne scars. METHODS: 65 patients with pitted acne scars were included in this study. All patients had skin types III or IV. All patients were instructed to use tretinoin cream 0.05% nightly for 2-4 weeks prior to the laser treatment. The pulsed erbium:YAG laser with a 2 mm handpiece at the setting of 500 mJ/pulse, 3.5-5 W in 45 patients and 1,000 mJ/pulse, 7-10 W in 20 patients was used. Two weeks after laser treatment, topical application of hydroquinone 4%, tretinoin 0.05%, and hydrocortisone 1% cream was recommended for 2-4 weeks. Facial photographs were obtained at baseline and 2 week intervals postoperatively. The results of treatment were evaluated for the changes of skin texture and color at 1 month, 3 months, and 6 months. RESULTS: In 45 cases treated with 500 mJ/pulse energy, pitted acne scars were improved about 46.7 % on average and no erythema and postinflammatory hyperpigmentation was observed after 6 months. In 20 cases treated with 1,000 mJ/pulse energy, pitted acne scars were improved about 64% on average and erythema in two patients and postinflammatory hyperpigmentation in one patient were observed after 6 months. CONCLUSION: The results of laser treatment for pitted facial acne scars at the setting of high energy are better than those of laser treatment at the setting of low energy.

Systemic lupus erythematosus is a systemic disorder which has frequent involvement of gastrointestinal tract. Non specific symptoms such as anorexia, nausea, diarrhea and abdominal pain are well known symptoms when the gastrointestinal tract is involved. The most feared gastrointestinal complication of systemic lupus erythematosus is lupus enteritis. The pathological change in lupus enteritis is usually a result of mesenteric vasculitis. Major complications such as intestinal bleeding and perforation may occur and sometimes result in sugery. Because of high mortality rate in case of major complications, early diagnosis and appropriate treatment is very important. We experienced three patients with lupus enteritis who presented with severe abdominal pain and dirrhea. They were diagnosed by characteristic radiographical findings of small bowel series and barium study. All radiographical findings has been resolved completely with the steroid therapy. Conclusively we can induce complete remission by steroid therapy alone, if we diagnose lupus enteritis in the early period of disease course.

High-voltage electrical burns are associated with deep muscle injuries. A hidden, deep muscle injury has no specific clinical manifestations, and undetected muscle injury sometimes leads to septisemia or major amputations. From January to December 1996, 52 burned patients were admitted to the burn center. We evaluated their laboratory findings and the results of diagnostic tools. The items of study were urine, EKG, CK-MB, CPK, LDH, SGOT, SGPT, PYP scanning, Plethysmography, and arteriography. The presence of myoglobinuria and the increase in SGOT and SGPT two weeks after the injury were related to the extent of the burns. The PYP scanning was a very sensitive and useful tool for detecting hidden muscle injuries. The arteriographic findings were unsatisfactory for deciding the amputation level. The PCR findings converting to obstructive type were helpful in predicting possibile amputations.

This study was designed to investigate dental arch shapes buccally and lingually at Bracket Level of Koreans. This involved studying 63 inviduals (37 males, 26 females) with normal occlusion ranging in age from 17 to 24 years old. The landmarks were digitized and measurements and statistical analysis were performed by NEC 9801 V-M computer. The Results were as Follows: Bicanine width, Bipremolar width and Bimolar width were larger in males than in females. Buccal and lingual arch form and coordination form were obtained by NEC 9801 V-M computer. The parabolic equations which represents buccal and lingual arch form were obtained.

Cystic parathyroid adenoma is one of the rare causes of hyperparathyroidism, and is usually located in neck and mediastinum. This type of adenoma tends to cause increased serum level of parathyroid hormone and alkaline phosphatase, similar serum calcium level when compared to those of solid adenoma. Thanks to current radioimmunoassay and easy accessibility to serum autoanalyzer, serum calcium level and parathyroid hormone level are more easily measured, which in turn lead to more easier diagnosis of hyperparathyroidism. Also improvement in imaging and nuclear diagnostic method of parathyroid lesion are suggested to enable easy diagnosis of cystic parathyroid adenoma. A 35-year-old male presented with easy fatigability for 12 months. The serum calcium, phosphate, alkaline phosphotase were 11.5mg/dL, 1.4mg/dL, 194IU/L respectively and his parathyroid hormone level in serum was 126.42pg/mL. Neck CT showed enlargement of right lobe of thyroid gland with well defined inhomogenously enhanced density inside the right thyroid gland. The patient was diagnosed of hyperparathyroidim due to parathyroid adenoma and was surgically removed. The surgical biopsy showed cystic parathyroid adenoma. After operation his general condition was improved and serum calcium, phosphate, parathyroid hormone level were normalizd. We report a case of hyperparathyroidism caused by cystic parathyroid adenoma with brief review of literature.

BACKGROUND: Although an oxidants and antioxidants imbalane has been considered in the pathogenesis of chronic obstructive pulmonary disease (COPD), there is a paucity of reports focussing on the smoking-induced changes of oxidants and antioxidants in COPD. METHOD: The concentration of antioxidants (ascorbic acid, uric acid, retinol, and α- &γ-tocopherol) was measured in the serum and induced sputum of 30 healthy controls and 34 stable COPD patients using high performance liquid chromatography (HPLC). The inhibition of lipid peroxidation as an index of antioxidant capacity was measured in the serum by a TBA assay. RESULTS: The serum concentration of ascorbic acid, α-tocopherol, and retinol were significantly lower in the patients with COPD than in healthy controls (484.8±473.3 vs 1497.8±819.2 pmol/L, p<0.001, 48.38±17.34 vs 73.96±26.29 pmol/L, p<0.001, and 9.51±8.33 vs 15.01±5.88 pmol/L, p<0.05, respectively, mean±SD). However, there were little differences in the ascorbic acid and uric acid concentrations in the induced sputum between the COPD patients and the controls. The induced sputum to serum ratio of ascorbic acid was significantly higher in COPD patients compared with healthy control (0.375 vs 0.085, p<0.05). In the normal controls, the serum ascorbic acid concentration was lower in smokers than in nonsmokers (1073±536 vs 1757±845 pmol/L, p<0.05), but the level was still higher than that of the COPD patients (p<0.05). The serum retinol levels were correlated with FEV1 in COPD patients (r=0.58, p<0.05). The products of lipid peroxidation were increased in normal smokers and COPD compared with normal nonsmokers (115.56±19.93 and 120.02±24.56 vs 91.87±20.71 µmol/µmol Pi of liposome, p<0.05). CONCLUSION: Cigarette smoking may induce the depletion of serum antioxidants and this depletion of antioxidants is suggested to play a role in the pathogenesis of COPD.
