Most cases of sparganosis in Thailand presented with superficial ocular mass lesions. The major risk behaviour in Thailand is drinking water contaminated with the infective organism. Some cases of serious deep visceral sparganosis have also been reported.

The quantitation of platelets in peripheral blood is a well-recognized tool. Recently, new indices related to erythrocytes and platelet counts have been provided by hematologic analyzers. Concerning the platelet parameter, the three important parameters are plateletcrit (PCT), mean platelet volume (MPV), platelet distribution width (PDW). The purpose of the study is to investigate these three parameters to define their expected values and the correlation with the parallel red blood cell parameters, hematocrit (HCT), mean corpuscular volumer (MCV), and red blood cell distribution width (RDW). Blood samples form 215 volunteers were analyzed for platelet parameters using Technicon H*3. The average (mean +/- SD) values obtained with expected ranges were PCT 0.24 +/- 0.05% (range, 0.23-0.24%), MPV 12.79 +/- 5.91 fL (range, 12.39-13.19 fL), and PDW 46.79 +/- 2.70% (range, 46.61-46.97%). Concerning the correlation between PCT, MPV, and RDW and their parallel red blood cell parameters, there was no significant correlation between PCT and HCT, and between MPV and MCV. However, there was a significant correlation between PDW and RDW. It seems that the anisocytosis of red blood cells and platelets might co-occur. However, these data are basic observations; further in-depth evaluation of the platelet parameters is recommended.

Dengue fever is a common tropical infection. This acute febrile illness can be a deadly infection in cases of severe manifestation, causing dengue hemorrhagic shock. In this brief article, I will summarize and discuss the diagnosis and treatment of this disease. For diagnosis of dengue, most tropical doctors make use of presumptive diagnosis; however, the definite diagnosis should be based on immunodiagnosis or viral study. Focusing on treatment, symptomatic and supportive treatment is the main therapeutic approach. The role of antiviral drugs in the treatment of dengue fever has been limited, but is currently widely studied.

Greater knowledge about blood donation does not lead to donation. Therefore, specific campaigns are needed to convert this into actual voluntary donation.

Background: One of the major health problems among HIV seropositive patients is superimposed infection due to the defect of immunity. Furthermore, intestinal parasite infection, which is also one of the basic health problems in tropical region, is common in these patients. In this study, a cross sectional study to document the prevalence of intestinal parasitic infection in Thai HIV-infected patients with different immune status was performed.
