Amelanotic maliganat melanoma is a comparatively rare disease. It accounts for 1.8~8.1% of all malignant melanoma. It is sometime difficult to diagnose amelanotic malignant melanoma because there is no pigmentation, clinically. Polypoid melanoma is a variant of nodular melanoma, which in depth seldom reaches the reticular dermis. The main part of the tumor is located above the nearby epidermis, raised in the form resembling cauliflower. We report a rare case of amelanotic malignant melanoma with polypoid feature in a 78-year-old woman who presented a single bright red nodule on the left thigh.

Tinea faciei is a dermatophyte infection of the glabrous part of facial skin most commonly caused by the Trichophyton species. Tinea faciale has been classified as part of tinea corporis but recently for its unique features, it is being considered a separate disease entity. Tinea faciale is a relatively rare dermatophytosis and is characterized by clinical polymorphism, which leads to frequent misdiagnosis and mistreatment with corticosteroids. Long term treatment with glucocorticoids can subsequently lead to tinea incognito. Herein we describe an unusual case of tinea faciei caused by T. mentagrophytes in a 40-year-old women with erythematous facial eruptions, initially misdiagnosed as allergic contact dermatitis and rosacea. By using mycological and histological examinations, dermatophytosis caused by Trichophyton mentagrophytes was confirmed. Oral terbinafine was administered together with topical clotrimazole and hydrocortisone for 4 weeks.

Basal cell carcinoma (BCC) is the most common of all skin cancers, and ultraviolet radiation is the major etiologic agent in the pathogenesis of BCC. BCC occurring on areas that are not exposed to the sun seems to have different pathogenesis that is not fully understood. Many histologic variants of BCC exist, reflecting its pluripotential origin from epithelial germ cells. Herein we report a case of BCC on the right axilla, which is an unusual place for its occurrence.

PURPOSE: This study was performed to improve cardiopulmonary resuscitation(CPR) training strategies for occupational groups, through the analysis of first responders' characteristics, knowledge and attitudes concerning CPR. METHODS: The occupational groups expected to have some training on rescue and emergency care in Korea were regarded as the first responders. In particular, this study focused on nurse-teachers, traffic policemen, and industrial safety supervisors, taxi drivers and restaurant workers as potential first responders, clerical workers comprised the control group. The subjects were given a questionnaire to answer over the internet. RESULTS: First responders' knowledge on CPR was significantly higher than that of the control group. First responders' attitude on CPR was more affirmative compared with the control group. In first responder group, nurse-teachers, traffic policemen and industrial safety supervisors had a higher fund of knowledge and more positive attitudes when compared to taxi drivers and restaurant workers. CONCLUSION: More training for first responders in CPR and emergency care is required given the likelihood of medical emergencies arising while on duty. Taxi drivers and restaurant workers' knowledge on CPR were found to be inadequate based on our survey questionnaire. Thus, it is necessary to strengthen CPR training for these individuals and groups.

OBJECTIVE: Postoperative seizure is a well documented complication of aneurysm surgery. The purpose of the present study was to analyze risk factors for postoperative seizure. METHODS: Between January 1990 and December 1996, we performed craniotomy for ruptured cerebral aneurysms in 321 patients. Among them 206 patients who could be followed up for more than 1 year(range, 1 to 4.6 years) were enrolled to present study. All patients were treated with anticonvulsants for 3 to 18 months postoperatively. We analyze the incidence of postoperative seizure in different sex and age groups, and risk factors associated with postoperative seizures following aneurysm rupture. For statistical processing chi-square test and Fisher's exact test were used. RESULTS: In the follow-up period of 1 to 4.6 years(mean, 1.8 years) postoperative seizure appeared in 18 out of 206 patients(8.7%). Mean latency between the operation and the first seizure was 6 months(range, 3 weeks to 18 months). The age of the patients has significant influence on the risk of seizure, it occurred more often in younger patients(p =0.0014). Aneurysm location in the MCA was associated with a significantly a higher risk of seizure(p =0.042). Eight patients(19%) out of 42 patients who suffered delayed ischemic neurologic deficit(DID) developed seizure. Delayed ischemic neurologic deficit was associated with significantly a higher risk of seizure(p =0.019). Infarct and hypertension were associated with significantly a higher risk of seizure(p < 0.05). pre- or postoperative intracranial hematoma(intracerebral or epidural hematoma) was associated with significantly a higher risk of seizure(p < 0.0001). H-H grade, Fisher grade, Glasgow Outcome Scale of patients and timing of operation after subarachnoid hemorrhage had no significant relation with the risk of seizure. CONCLUSION: Factors associated with the development of postoperative seizure were middle cerebral artery aneurysm, delayed ischemic neurologic deficit, infarct on late postoperative CT scan, hypertension, pre or postoperative intracranial hematoma(intracerebral or epidural hematoma). Identification of the risk factors may be help to focus the antiepileptic drug threapy in cases prone to develop seizures. Prospective evaluation is indicated.

BACKGROUND: The objective of this study was to examine the correlation between arterial blood gas (ABG) and peripheral venous blood gas (VBG) samples for all commonly used parameters in patients admitted to a medical intensive care unit (ICU). METHODS: A single-center, prospective trial was carried out in a medical ICU in order to determine the level of correlation of ABG and peripheral VBG measurements. A maximum of five paired ABG-VBG samples were obtained per patient to prevent a single patient from dominating the data set. RESULTS: Regression equations were derived to predict arterial values from venous values as follows: arterial pH=-1.108+1.145xvenous pH+0.008xPCO2-0.012xvenous HCO3+0.002xvenous total CO2 (R2=0.655), arterial PCO2=88.6-10.888xvenous pH+0.150xPCO2+0.812xvenous HCO3+0.124xvenous total CO2 (R2=0.609), arterial HCO3=-89.266+12.677xvenous pH+0.042xPCO2+0.675xvenous HCO3+0.185xvenous total CO2 (R2=0.782). The mean ABG minus peripheral VBG differences for pH, PCO2, and bicarbonates were not clinically important for between-person heterogeneity. CONCLUSION: Peripheral venous pH, PCO2, bicarbonates, and total CO2 may be used as alternatives to their arterial equivalents in many clinical contexts encountered in the ICU.
