Common alpha-thalassemia deletions in transfusion-dependent thalassemia patients in the Southeast Asia region of Myanmar.

Screening of 3 common alpha-thalassemia (thal) deletions (-alpha3.7, -alpha4.2 and --SEA) in Southeast Asia was done by polymerase chain reaction in 170 unrelated Myanmar thal patients receiving transfusions.

Active surveillance for congenital rubella syndrome in Yangon, Myanmar.

Objective: Rubella vaccine is not included in the immunization schedule in Myanmar. Although surveillance for outbreaks of measles and rubella is conducted nationwide, there is no routine surveillance for congenital rubella syndrome (CRS). Therefore, we organized a study to assess the burden of CRS.

Myanmar dengue outbreak associated with displacement of serotypes 2, 3, and 4 by dengue 1.

In 2001, Myanmar (Burma) had its largest outbreak of dengue-15,361 reported cases of dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS), including 192 deaths. That year, 95% of dengue viruses isolated from patients were serotype 1 viruses belonging to two lineages that had diverged from an earlier, now extinct, lineage sometime before 1998. The ratio of DHF to DSS cases in 2001 was not significantly different from that in 2000, when 1,816 cases of DHF/DSS were reported and dengue 1 also was the most frequently isolated serotype.

Dengue hemorrhagic fever in infants: research opportunities ignored.

The age distribution of cases of dengue hemorrhagic fever and dengue shock syndrome (DHF/DSS) in infants under the age of 1 year are reported from Bangkok, Thailand, and for the first time for Ho Chi Minh City, Vietnam; Yangon, Myanmar; and Surabaya, Indonesia. The four dengue viruses were isolated from Thai infants, all of whom were having a primary dengue infection. Progress studying the immunologically distinct infant DHF/DSS has been limited; most contemporary research has centered on DHF/DSS accompanying secondary dengue infections.

A wider molecular spectrum of beta-thalassaemia in Myanmar.

Two hundred and nine beta-thalassaemia (beta-Thal) alleles of 158 unrelated Myanmar patients (107 HbE-beta-Thal; 51 beta-Thal major) were analysed for beta-globin gene mutations. Amplification refractory mutation system (ARMS) characterized six beta-thal mutations known to Myanmar [betaIVSI-1(G-->T), codon 41/42(-TCTT), betaIVSI-5(G-->C), codon 17(A-->T), betaIVS II-654(C-->T), and -28 Cap (A-->G)] in 166/209 (79.4%) alleles.

Investigation of small-intestinal transit time in normal and malnourished children.

We aimed to establish whether there was a variation in orocecal transit time (OCTT) in Myanmar children and whether shortened transit time correlated with malnutrition. OCTT was measured in 90 healthy Myanmar children aged 1-5 years, using the hydrogen breath test (10g in 10% aqueous solution). The relationships between OCTT, sex, age, and malnutrition status were assessed.

Serum cortisol levels in children with dengue haemorrhagic fever.

Dengue Haemorrhagic Fever (DHF) is a serious and often fatal paediatric problem in Myanmar. Acute and convalescent serum cortisol levels were measured in 62 children with dengue infection to study cortisol sufficiency in this disease. Twenty-six children with non-dengue acute viral infection were also included as controls.

High-calorie, rice-derived, short-chain, glucose polymer-based oral rehydration solution in acute watery diarrhea.

In this study, we have compared the effects of the World Health Organization oral rehydration solution (WHO ORS) and an ORS containing short polymers of glucose (Amylyte ORS) at a high caloric density (five times) and comparable osmolality, on stool output, duration of diarrhea, weight gain and fluid and electrolyte balance, in randomized, open-labeled, controlled clinical trials in five centers. A total of 198 male children (4 months to 10 years) with acute diarrhea ( <72 h after onset) were assigned by random allocation to either WHO ORS or Amylyte ORS at five centers in Asia. Children were stratified according to grade of dehydration (mild, moderate or severe) and the initial purging rates during the first 6 h (low ( < 2 ml/kg/h), moderate (2-5 ml/kg/h) and high ( > 5 ml/kg/h) purgers).

Thermophilic amylase-digested rice-electrolyte solution in the treatment of acute diarrhea in children.

Objective: To compare the efficacy of an oral rehydration solution (ORS) containing short polymers of glucose derived from rice (Amylyte-ORS) and five times the caloric density of current ORS to the standard glucose-ORS (World Health Organization [WHO] = ORS) in the treatment of acute diarrhea in children.

Methods: The rice ORS (Amylyte-ORS) was obtained by adding thermophilic amylase (252,500 MW units) and salts (1.5 g NaCl, 600 mg KCl, and 150 mg CaCl2) to 100 g rice and boiling for 10 minutes in 500 mL water.

A prospective study on defecation frequency, stool weight, and consistency.

It has been commonly believed that children in developing countries pass stools that are very different from those of developed countries. A community based study on defecation frequency, stool weight, and consistency was conducted in a cohort of 300 Myanmar (Burmese) children aged 1 to 4 years. Most (80.

Thalassemia in the outpatient department of the Yangon Children's Hospital in Myanmar: cost analysis of the day-care-room services for thalassemia.

A cost analysis study for the fiscal year 1989-1990 was conducted in the day care room (DCR) for thalassemia patients at the Yangon Children's Hospital in Myanmar to provide a basis for future cost-effectiveness, cost-benefit and efficiency analyses. Two types of costs, hospital costs and costs borne by the patients' families were studied by reviewing hospital records and by interviewing family members of patients. Of the total cost of DCR services for thalassemia 74 to 75% was contributed by material costs most of which were for imported items.

Thalassemia in the outpatient department of the Yangon Children's Hospital in Myanmar: knowledge, attitudes and practice in relation to thalassemia.

A maternal knowledge, attitudes and practice (KAP) study concerning the nature and prevention of thalassemia was carried out at the Yangon Children's Hospital in Myanmar. The KAP information was collected using a pretested schedule. Only 18 to 28% of the mothers knew at least one of the statements: thalassemia is a genetic disorder; both parents of thalassemic children carry abnormal genes; there is a 25% chance of recurrence in each subsequent pregnancy.

Thalassemia in the outpatient department of the Yangon Children's Hospital in Myanmar: basic hematological values of thalassemia traits.

The present study was conducted in the Outpatient Department (OPD) of Yangon Children's Hospital (YCH) during June to November 1990 to determine the hematological data of 133 Myanmar patients with thalassemia trait who were the parents of patients with known beta-thalassemia major or hemoglobin E (Hb E)/beta-thalassemia. The mean values of hemoglobin (Hb) concentration, packed cell volume (PCV), mean cell hemoglobin (MCH) and mean cell volume (MCV) were significantly lower than normal controls but the mean cell hemoglobin concentration (MCHC) was the same as controls. Increased osmotic resistance tested in 0.

Comparison of glucose/electrolyte and maltodextrin/glycine/glycyl-glycine/electrolyte oral rehydration solutions in acute diarrhea in children.

Male children (N = 101) 6-35 months of age presenting with acute watery diarrhea for less than 48 h at home before hospitalization were admitted into a randomized, double-blind clinical trial. Fifty-one children were treated with standard oral rehydration solution (ORS) (World Health Organization [WHO] formulation containing citrate) and 50 were treated with an improved ORS formulation (containing, in addition to the standard formula, 20 g maltodextrin instead of glucose, and 4 g glycine and 4 g glycyl-glycine). None were given antibiotics.
