Three anopheline mosquitoes in Korea were studied for their abilities as vectors for Plasmodium vivax. The female mosquitoes of Anopheles lesteri, An. pullus and An. sinensis were allowed to suck malaria patient blood until fully fed, and they were then bred for 2 weeks to develop from malaria parasites to sporozoites. The result from the above confirmed the sporozoites in one An. lesteri of one individual and five An. sinensis of six individuals. We also reconfirmed that An. sinensis was the main vector to transmit malaria and An. lesteri as well as An. sinensis were able to carry Korean malaria parasites. Therefore, we propose that diversified study is needed to manage malaria projects.

Lichen planopilaris (LPP) is a follicular variant of lichen planus, typically occurring on the scalp. A 61-year-old man presented with asymptomatic pigmented atrophic patches on his chin. Dermoscopy showed reticular hyperpigmentation and perifollicular hyperkeratosis. A punch biopsy revealed follicular plugging, perifollicular lymphocytic infiltration, vacuolar degeneration of the follicular basal cell layer, mild interface dermatitis, and melanophages. Direct immunofluorescence testing was negative, leading to a diagnosis of facial LPP. Some have classified similar cases as facial LPP, while others have reported them as a follicular variant of lichen planus pigmentosus. This report explores the question of whether these cases should be classified as facial LPP, or as a follicular variant of lichen planus pigmentosus, or as conditions encompassed within the spectrum of these two disorders, with a comprehensive literature review.

Endoscopic variceal ligation(EVL) is newly developed method to manage esophageal variceal bleeding. This study asse initial control rate of active variceal bleeding, incidence of rebleeding and complications in EVL. From June in l992 to December in 1994, this study was performed on 70 patients who had visited to our medical center for melena or hematemesis by acute esophageal variceal bleeding. In all of 70 cases, eradication of esophageal varix was performed and variceal bleeding was controlled well. And first session was performed successfully with EVL. But rebleeding was occured in 12 cases(11 cases caused by esoyhageal varix and 1 case caused by esophageal ulcer) during follow-up period, so EVL therapy was performed repeatedly and 8 cases were eradicated and 4 cases were uncontrolled and died, and then 94% hemostatic effect was achieved during follow-up period. Complications of EVL therapy were mild(substernal discomfort in 12 cases, substernal pain in 4 cases, fever in 3 cases, mild dysphagia in 2 cases) and well controlled. Superficial esaphageal ulcer was shown in 18 cases by follow-up endoscopy after 1 week. These results show that EVL is a good therapeutic method to control active variceal bleeding and eradication of varix with repeat treatment. In conclusion, EVL is an effective and safe method of treatment and prevention for esophageal variceal bleeding.

In order to study the range of flight and feeding activity of Anopheles sinensis, the dispersal experiment was conducted in Paju city, located in the northern part of Gyeonggi-do, Republic of Korea, during the period of 7th to 28th September 1998. Unfed females An. sinensis were collected in cowshed and released after being marked with fluorescent dye at 23:00 hours on the same day. Released female mosquitoes were recaptured everyday during 21 days using light traps, which were set at 10 sites in the cowsheds located 1, 3, 6, 9 and 12 km north-northwest and north-northeast and at 3 sites located 1, 6 and 9 km toward south-west from the release point. In addition, to study the longest flight distance in one night, we set the light traps at 16 and 20 km toward north-northeast from the release site. All the collected mosquitoes were placed on filter papers and observed on UV transilluminator after treatment with one drop of 100% ethanol. Out of 12,773 females of An. sinensis released, 194 marked females mosquitoes were recaptured, giving 1.52% recapture rate. Of 194, 72 mosquitoes (37.1%) were recaptured in light traps from three places set at 1 km from the release point, 57 mosquitoes (29.4%) from two places at 1-3 km, 41 mosquitoes (21.1%) from three places at 3-6 km, 20 mosquitoes (10.3%) from three places at 6-9 km, and 4 mosquitoes (2.1%) from two places at 9-12 km. Since 170 female mosquitoes (87.6%) out of 194 marked mosquitoes were captured within 6 km from the release point, this flight radius represents the main activity area. An sinensis was found to be able to fly at least 12 km during one night.

The frequency of intestinal tuberculosis is relatively common; however, primary tuberculosis of the appendix remains a rarity. We report on a case of primary tuberculous appendicitis for which we obtained the MDCT images revealing thickening of the appendix and the surrounding lymphadenopathies.

BACKGROUND: The heavy-light chain (HLC) quantitative test can identify and quantify the heavy and light chains of each immunoglobulin class. The purpose of this study was to evaluate the effectiveness of the HLC quantitative test. METHODS: To evaluate the effectiveness of the HLC quantitative test, a systemic review of the literature, using Ovid-MEDLINE, EMBASE, Cochrane library, and eight domestic databases including KoreaMed, was performed until October 10, 2013. We included five cohort studies and one diagnostic evaluation study in the final evaluation. Two reviewers independently assessed the quality of the included studies and extracted data from the studies. The quality of the studies was assessed according to the Scottish Intercollegiate Guidelines Network (SIGN) tool. RESULTS: A correlation between the HLC quantitative test and previous assays was evaluated in one study, which enrolled patients with increased monoclonal IgA. The correlation coefficient was reported as 0.94 in this study. The clinical significance of the quantitative HLC test to predict a prognosis was also reported in five cohort studies. The survival rate in patients with higher HLC ratio was significantly lower and the increased IgA kappa/lambda ratio or IgM kappa/lambda ratio was significantly correlated with higher survival rate in patients with monoclonal gammaglobulinemia. CONCLUSIONS: The HLC quantitative test is an effective test that can quantitatively measure the identified immunoglobulin type and predict the prognosis of patients with monoclonal gammopathy.
