    Assessing the accuracy of respiratory rates at different counting periods and methods
    (1996-01-01) Khin Myat Tun; Phyu Phyu Aung; Thida Kyaw; Khin Saw Aye; Thein Shwe; Le Le Win; Soe Aung
    The respiratory rates of 198 children (aged 2-59 months) suffering from acute respiratory infections (ARI) were monitored by observation, palpation and auscultation (Gold standard). Two 30-second and one 60-second counts were obtained. The difference among respiratory rate counts determined simultaneously by observation, palpation and auscultation in relation to their mean count was analyzed for 60-second counting period, 30 plus 30-second period and 30-second doubled. The variability among the different counting methods and counting periods was not significantly different whether the children were feeding, sleeping, resting and awake or awake but not resting. The data from the study suggest that respiratory rate counting either by observation or palpation are similar in accuracy and one minute's counting either at a stretch or 30-second doubled or two blocks of 30-second intervals are also similarly accurate.

    Assessment of the erythrocyte protoporphyrin test for screening of iron deficiency anaemia
    (1994-12-01) Khin Myint Myint Kyaw; Khin Myat Tun; Than Than Lwin; Tin Moe Moe; Phyu Phyu Aung; Khin Saw Aye; Thida Kyaw; Tin Nu Swe
    A total of 84 apparently healthy children between ages of 1-12 years were screened for iron deficiency with the erythrocyte protoporphyrin (EP) test. Serum iron, total iron binding capacity in serum, percent transferrin saturation, haematocrit and haemoglobin values were also determined together with the screening test. Comparing the relationship between EP and percent transferrin saturation, using a percent transferrin saturation value < 10 percent as the criterion of iron deficiency, the optimal cut off limit for the EP test appears to be 80 ug/dl of rbcs. At this level, this screening test showed a sensitivity of 74 percent and specificity of 95 percent and the positive and negative predictive values were 82 percent and 93 percent respectively. thus EP assay which is less expensive and easy to perform can be used as a screening test for the detection of iron deficiency.

    Histopathological severity of antral gastritis in relationship to Helicobacter pylori colonisation
    (1997-01-01) Than Than Htwe; Myo Khin; Kyaw Hla; Than Than Swe; Tin Nu Swe; Khin Myat Tun; Thida Kyaw
    The association between Helicobacter pylori (HP) colonisation in gastric antrum and the degree of severity and activity of gastritis and the concomitant relationship with gastric atrophy and intestinal metaplastic changes were studied. A total of 204 pieces of endoscopic biopsy tissues were collected from the outpatient endoscopy unit of New Yangon General Hospital in 1994. Routine Haematoxylin and Eosin stain as well as special stains such as modified Giemsa and Carbol fuchsin stains were used for bacterial identification and quantitative analysis. a significant correlation (P value <0.001) was obtained between density of HP colonisation and severity of gastritis as well as its activity (p value <0.001). However, no significant degree of atrophic changes and intestinal metaplastic changes were noted in these biopsies. a continuation for a better understanding of the pathogenesis of HP and its consequences is necessary.

    Is oral rice-based electrolyte solution superior to glucose electrolyte solution in acute chidhood diarrhoea?
    (1995-04-01) Khin Myat Tun; Thida Kyaw; Khin Saw Aye; Tin Aye; Kyaw Moe; Thein Thein Myint; Thein Aung; Tin Oo; Tin Nu Swe; Soe Aung
    In a controlled trial of oral rehydration therapy, the efficacy and safety of rice-based electrolyte solution was compared with standard WHO oral rehydration solution. Ninety eight male children aged 4 months to 10 years presenting with watery diarrhoea of less than 72 hours prior to hospitalization were studied. 48 were treated with standard WHO oral rehydration solution (ORS) and 50 patients with an improved formulation which contained 100 gm of rice (instead of glucose) with 25 mg of amylase in addition to electrolytes. The clinical characteristics of the two groups on, admission were comparable. Although there was a consistent trend towards reduction in stool volume and better gain in body weight in children with cholera treated with rece-based ORS, significant difference was noted only in 6-12 hour stool output and in the first 6 hour weight gain. Stool volume was significantly reduced during the 24 to 48 hour perild in all diarrhoeal patients receiving rice-based ORS. Thus, amylyte digested rice-based ORS is as effective as the Standard WHO ORS and have some therapeutic advantage in the treatment of acute childhood diarrhoea.
