Scrub typhus is common among patients with acute fever in rural areas of Thailand. The authors prospectively recruited patients with acute fever from provincial Thai army hospitals. Dot-ELISA test for scrub typhus was done in hospitals and then compared with standard immunofluorescent assay for diagnosis of scrub typhus.

Chromosome analysis of uncultured amniocytes by comparative genomic hybridization in early amniocentesis.

Objective: To study chromosome analysis by comparative genomic hybridization (CGH) compared with the conventional technique in early amniocentesis.

Material And Method: Cross-sectional descriptive study design was performed in 32 singleton pregnant women with gestational age between 12-15 weeks. Transabdominal amniocentesis was carried out under ultrasound guidance.

Prenatal diagnosis of Hb Bart's hydrops fetalis by PCR technique: Pramongkutklao experience.

Hb Bart's hydrops fetalis is very common in Southeast Asia, especially in Thailand. As the mother of such an infant may suffer from toxemia of pregnancy, ante- or post-partum hemorrhage as well as the psychological burden for carrying a nonviable fetus to term, so prenatal diagnosis is indicated and the family should be given the choice of early termination of the pregnancy. Seven high risk pregnancies with Hb Bart's hydrops fetalis (homozygous alpha-thalassemia 1) were studied.

Mosaic hexasomy 21.

Cases in which there are more than three copies of a sex chromosome, and rarely of an autosome, have been reported, but to our knowledge hexasomy has never been described except in tissue undergoing neoplastic change. This report describes a female infant with multiple malformations in whom we found a mosaic hexasomy 21. This was first detected in amniotic fluid cells and subsequently in skin fibroblasts.
