We compared the performance of three screening kits for the detection of anti-HIV in 187 samples; Enzygnost Anti-HIV 1/2 Plus, ABBOTT TESTPACK HIV- 1/HIV-2 & SERODIA. HIV- 1/2. Four samples, 3 serums and 1 CSF, from 2 patients were repeatedly reactive in all three screening kits and 2 serum specimens were confirmed positive(HIV-1) by the western blot assay. The sensitivity and specificity of all three screening kits were 100% and 98.9%, respectively. In Korea, the cause of AIDS is mostly HIV-1 and the prevalence is very low. So, all three screening kits were useful for the detection of anti-HIV from patients and blood donors. But the use of screening kit for the detection of anti-HIV-1, anti-HIV-2 and anti-HIV-I subtype O will be needed for the decrement of false negative rate because HIV infection has been increased, especially, HIV-2 infection and pediatric AIDS patient by vertical transmission were also reported, currently.

BACKGROUND: Microalbuminuria is the main parameter used in diabetic patients for clinical evaluation of early diabetic nephropathy and other complications. The most common method for quantitative urinary protein relies on a 24-hour urine collection or overnight urine collection; however, this method is time consuming and sometimes obtains inaccurate results. This study is aimed to test whether the microalbumin to creatinine ratio (Uma/Ucr) in the first-morning urine samples correlates with the microalbumin content in the 24-hour urine collection. METHODS: 59 urine samples from 59 type 2 diabetic patients were analyzed for Uma/Ucr, and for 24-hour urine microalbumin that were successively collected. RESULTS: Daily microalbumin excretion varied from 2.4 to 168.7 mg/24 hr with a median value of 22.9 mg, and Uma/Ucr ranged from 3.4 to 200 g/mg with a median value of 29.0 g/mg. An excellent correlation was found between the microalbumin excretion measured from the 24-hour urine collections and the first-morning urine Uma/Ucr ratio (R=0.93, P<0.001). All patients that excreted more than 30 mg albumin in the 24-hour urine samples also had an Uma/Ucr of more than 30 g/mg. Patients who had less than 30 g/mg of Uma/Ucr were unlikely candidates for microalbuminuria. CONCLUSIONS: This study indicates that measurements of Uma/Ucr in first-morning urine samples are a simple and reliable alternative to measurements of the urinary albumin excretion rate in the 24-hour urine collections.

BACKGROUND: Classical surgical treatment of axillary osmidrosis and hyperhidrosis results in many complications such as scarring, hematoma and necrosis, therefore, gentle skin flap cares is needed. OBJECTIVE: In order to lessen the complications and to obtain an improved clinical outcome, a new easy-learn, surgical excision method of treating subcutaneous tissue is required. METHOD: On 16 patients, We carried out a type-1 surgical method to treat axillary osmidrosis and hyperhidrosis. This invoved major removal of the subcutaneous tissue by scissor excision, and partial removal by the subwtaneous shaver method, to minimise trauma. We then analyzed the clinical efficiency, complications, patient satisfaction, and pathologic specimens according to clinical severity. RESULTS: All 16 patients showed an improved odor or sweating pattern, and a good or very good level of satisfaction. One patient also showed that hematoma was improved with proper post- operative care. Hyperactivity of the apocrine glands in osmidrosis and eccrine gland in hyperhidrosis was seen, and various morphologic features of apoeccrine glands were found in both osmidrosis and hyperhidrosis. We observed that apocrine and eccrine glands were completely excised by following the biopsy of 2 patients. CONCLUSION: Our present method of minimal skin incision and major removal of subcutaneous fat with manual scissor excision, in combination with partial excision with the subcutaneous shaver method, showed a good clinical outcome and few complications.

Approximately 6% of all head and neck skin cancers arise from the external ear, of which squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are the most common. Acquired helical rim defects can be caused by injury or after excision of a tumor. Since many patients feel that the auricle has a functional and cosmetic importance, it is crucial to consider the esthetics. In cases where the defect exposes bare cartilage, second-intention healing is usually not achieved. Therefore, full-thickness skin grafts have been adopted, but the healing time is long and in many cases, mismatch of color between the grafted skin and the surrounding ear has been observed. Alternatively, reconstruction with flaps may provide optimal coverage. Among the many possible flap designs, the rhombic transposition flap has become widely utilized in dermatologic surgery, due to its simplicity and versatility. Herein, we report a case of SCC on the superior helical rim (of which the cartilage was spared) successfully managed with a rhombic transposition flap. The surgical procedure had been relatively simple and the resultant ear helix was free from deformity. In future, we recommend that defects of the ear helix, which have an intact cartilage, should be treated with a rhombic transposition flap to give a successful cosmetic and functional outcome.

Leukemia cutis, the specific infiltration of leukemia, can be seen in any leukemia, but, are especially common in the acute myelogenous leukemia M4 and M5 variants. It may clinically mimic many inflammatory dermatoses. We herein report a case of a 59-year-old man with acute monocytic leukemia who concurrently presented with various cutaneous manifestations that clinically resembled benign skin lesions such as rosacea, contact dermatitis, and milium. Histologic study of all the lesions revealed leukemia cutis of the monocytic type. We presented this case to illustrate how leukemia cutis can masquerade as clinically benign-appearing, cutaneous eruptions.

The introduction of a new, fully automated system into the clinical microbiology laboratory contributes to a rapid identification of microorganisms with accurate and reliable results, but such a system requires a high cost and additional tests for identification of some species. For instance, additional tests on oxidase, indole, motility, hemolysis, and pigmentation are needed in the correct identification by using Vitek GNI+ system (bioMerieux Vitek Inc., MO, USA). In particular, Vibrio and Aeromonas species are occasionally identified incorrectly when an automated system is used, and thus conventional biochemical tests may be more reliable in the identification of such species. We experienced three cases of incorrect identification of Vibrio parahaemolyticus, Vibrio cholerae, and Aeromonas veronii biovar sobria as Vibrio alginolyticus by using Vitek GNI+ card.

Nevus sebaceus is well-known for its potential to develop both benign and malignant neoplasms of epidermal and adnexal origin. We found 5 tumors including syringocystadenoma papilliferum, a basal cell carcinoma-like tumor, sebaceous epithelioma, a tumor of follicular infundibulum and apocrine adenoma within a single nevus sebaceus lesion in a 37-year-old man. This is a rarely reported case of a nevus sebaceus lesion containing a basal carcinoma-like, trichoblastoma-like skin tumor and tumors of follicular infundibulum. The lesion was treated by wide excision and repaired with subgaleal-periosteal fixation which resulted in good wound healing.
