Steatocystoma simplex or solitary steatocystoma, first reported by Brownstein in 1982, is exceedingly rare. It is characterized by solitary, noninherited tumor in adults and seems to be a counterpart of steatocystoma multiplex with an identical histologic pattern. We describe a case of steatocystoma simplex in a 52-year-old woman who had a bluish papule on the nose. Histopathological findings showed a thin-walled cyst lined by stratified squamous epithelium with hyaline cuticle and sebaceous glands in or near the wall. We think that this is the first report of steatocystoma simplex in Korean literature.

BACKGROUND: Helicobacter pylori(H. pylori) infection is known to be strongly associated with varied dermatoses such as rosacea, vasculitic purpura, and Sweet's syndrome. Also, many antibiotics including amoxicillin, clarithromycin, and tetracycline have been used to ameliorate chronic urticaria. This recent knowledge posed the plausibility that H. pylori infection might be an underlying causative factor of chronic urticaria. OBJECTIVE: This study was conducted to investigate the role of H. pylori infection in patients with chronic urticaria. METHODS: Sixty-five subjects with chronic urticaria were examined for H. pylori infection with enzyme-linked immunosorbent assay for IgG/M against H. pylori and rapid urease test(CLO test) for endoscopically biopsied gastric mucosa. Amoxicillin or clarithromycin combined with omeprazole as a therapy was administrated to the 44 patients with positive test results for 4 weeks. RESULTS: H. pylori infection was more frequently diagnosed in 44 of 65(67.7%) patients with chronic urticaria than in the control subjects(8.8%). After the completion of treatment for 4 weeks, specific IgG antibodies and a CLO test against H. pylori were negative in 28 of 38(73.7%) and 43 of 44(97.7%) patients respectively. At the post-treatment evaluation, 37 of 44(84.1%) patients with H. pylori-positive urticaria showed significant clinical remission of urticaria. CONCLUSION: Eradication of H. pylori in patients with chronic urticaria was accompanied by clinical remission of urtication. There is substantial evidence that unexplained causes of chronic urticaria may be associated with H. pylori infection.

BACKGROUND: Epinephrine used in surgery to provide hemostasis may elicit ventricular arrhythmias. A desirable anesthetic would not sensitize the myocardium to exogenously administered epinephrine. So the effect of sevoflurane, which was introduced to clinical anesthesia recently, on cardiac arrhythmias induced by the infusion of epinephrine was compared with those of halothane which was already known to epinephrine-induced arrhythmia in the 14 mongrel dogs. METHODS: The authors compared the arrhythmogenicity (three or more premature ventricular contractions, PVCs)of intravenously administered epinephrine in 14 mongrel dogs who were randomly assigned to receive sevoflurane (1.7 vol%) or halothane (0.75 vol%) anesthesia equipotently. The arrhythmogenic doses of epinephrine determined in this comparative study were expressed by both infusion rates of epinephrine during sevoflurane and halothane anesthesia. RESULTS: The mean values of the arrythmogenic infusion rates of epinephrine were 27.1 7.6 g/kg for sevoflurane and 2.7 0.8 g/kg for halothane. CONCLUSIONS: We concluded that the arrythmogenic doses of epinephrine during sevoflurane were significantly higher than those during halothane anesthesia.

Angioleiomyoma(ALM) of the cavernous type is a rare subtype of leiomyomas arising from the smooth muscle of veins. ALM of this type invariably shows clinically and histopathologically distinctive features, compared with the classical solid or venous type. However, no case of ALM of this type has been yet reported in Korea although there have been several reported cases of other types. We herein present the case of a 39-year-old man with a 7-year history of a painless ALM of the cavernous type on his buttock with the histological features of markedly ectatic vascular channels and thin intervascular bundles of smooth muscles.

OBJECTIVE: To investigate the response of hyperplastic endometrium to Medroxyprogesterone acetate according to the histologic types such as simple typical, complex typical and atypical hyperplasia. METHODS: A total of 79 patients with histologically proved endometrial hyperplasia were enrolled into this prospective study between March 1996 and May 1998. Patients without atypia were placed on a regimen of cyclic therapy with 10mg MPA orally, each day for 14days per month for 3 months. In the cases in which hyperplasia did not regress , MPA was increased to 20mg. Patients with atypical hyperplasia received continuous MPA therapy, 20mg orally each day for 3 month. All patients were followed up for a minimum of 3 months and a maximum of 1 year(mean 7 months). RESULTS: In patients with simple typical hyperplasia, 45 patients(80.4%) had regression, 11 patients(19.6%) had persistence and none had progression. In patients with complex typical hyperplasia, 10 patients(83.3%) had regression, 2 patients(16.7%) had persistence and none had progression. But, in patients with atypical hyperplasia 5 patients(45.4%) had regression, 4 patients(36.4%) had persistence and 2(18.2%) patients had well differentiated endometrial adenocarcinoma. There was no recurrence during the follow up. CONCLUSION: This data suggest that most women with typical hyperplasia respond to progestin therapy, but there is high failure rate of response to progestin therapy and risk of endometrial cancer in patients with atypical hyperplasia. If the young patient desires to preserve her fertility, then progestin therapy may be considered as primary treatment in patients with atypical hyperplasia. But older patients in whom fertility is not an issue, hysterectomy should be selected as treatment of choice for atypical lesion.

PURPOSE: We examined the relationship between BIS, sedation score and plasma midazolam concentration to verify the usefulness of BIS to assess the patient's consciousness during sedation. PATIENTS AND METHODS: Twenty-five young, healthy adult volunteers participated in this clinical study. Midazolam was administered intravenously up to 0.08 mg/kg to induce unconsciousness and we monitored the patient's physiological and conscious status until complete recovery from sedation. BIS and sedation score were measured before sedation, 10, 20, 30 minutes after midazolam administration. Plasma midazolam concentration was measured 10 minutes after midazolam administration. BIS was measured using A-2000 BISTM monitor (Aspect Medical Systems, USA) and the degree of sedation was evaluated with the sedation score. RESULTS: The BIS score correlated with the sedation score (r = 0.676, P < 0.05). With the decreased plasma midazolam concentration, the correlation was better with sedation score(r = -0.656).Although BIS values did not correlate with calculated plasma concentration of midazolam (r = 0.467) at 10 minutes after midazolam administration, values after sedation were well distinguished from those before sedation. CONCLUSIONS: BIS is known for an effective predictor of patient's hypnotic state, and it is correlated with the sedation score. But, it doesn't always coincide with the clinical parameters of depth of sedation. So more attention is needed using BIS only during sedation, and it is advisable that the patient's consciousness is monitored with variable sedation score systems every several minutes.
