BACKGROUND Recent outbreaks of avian influenza A (H5N1) in poultry throughout Asia have had major economic and health repercussions. Human infections with this virus were identified in Vietnam in January 2004. METHODS We report the clinical features and preliminary epidemiologic findings among 10 patients with confirmed cases of avian influenza A (H5N1)(More)
In southern Vietnam, a four-year-old boy presented with severe diarrhea, followed by seizures, coma, and death. The cerebrospinal fluid contained 1 white cell per cubic millimeter, normal glucose levels, and increased levels of protein (0.81 g per liter). The diagnosis of avian influenza A (H5N1) was established by isolation of the virus from cerebrospinal(More)
BACKGROUND Dengue shock syndrome is characterized by severe vascular leakage and disordered hemostasis and progresses to death in 1 to 5 percent of cases. Although volume replacement is recognized as the critical therapeutic intervention, World Health Organization management guidelines remain empirical rather than evidence-based. METHODS We performed a(More)
Consecutive fluoroquinolone (FQ)-resistant isolates (n = 109) identified at the Pham Ngoc Thach Hospital for Tuberculosis, Ho Chi Minh City, Vietnam, were sequenced in the quinolone resistance-determining regions of the gyrA and gyrB genes and typed by large sequence polymorphism typing and spoligotyping to identify the Beijing genotype of Mycobacterium(More)
BACKGROUND It is uncertain whether all adults with bacterial meningitis benefit from treatment with adjunctive dexamethasone. METHODS We conducted a randomized, double-blind, placebo-controlled trial of dexamethasone in 435 patients over the age of 14 years who had suspected bacterial meningitis. The goal was to determine whether dexamethasone reduced the(More)
Multidrug-resistant tuberculous meningitis is fatal without rapid diagnosis and use of second-line therapy. It is more common in human immunodeficiency virus (HIV)-positive patients. Beijing genotype strains of Mycobacterium tuberculosis are associated with drug resistance, particularly multidrug resistance, and their prevalence is increasing worldwide. The(More)
The mechanisms underlying the bleeding manifestations and coagulopathy associated with dengue remain unclear, in part because of the focus of much previous work on severe disease without an appropriate comparison group. We describe detailed clinical and laboratory profiles for a large group of children with dengue of all severities, and a group with similar(More)
Clostridium tetani is the etiologic agent of the muscle-spasming disease tetanus. Despite an effective vaccine, tetanus is an ongoing problem in some developing countries. Diagnosis by bacterial culture is not done because it is generally unnecessary and the entry of route of the bacteria can be inapparent. We attempted to isolate and evaluate C. tetani(More)
BACKGROUND Streptococcus suis infection, an emerging zoonosis, is an increasing public health problem across South East Asia and the most common cause of acute bacterial meningitis in adults in Vietnam. Little is known of the risk factors underlying the disease. METHODS AND FINDINGS A case-control study with appropriate hospital and matched community(More)
