Acceptance of short course artesunate plus mefloquine drug combination by malaria patients in rural Myanmar.

A cross sectional study was carried out in a rural area of Myanmar to identify malaria patients' acceptance of artesunate plus mefloquine drug combination and to determine the cost borne by patients. The majority (88.5%) preferred this new regimen rather than the other ones they had used before; conviction of drug efficacy was the reason given for the preference by most of them. Traveling on foot to rural health centers or a health assistant's residence for getting the drugs was found to be the main route. Average cost incurred by a patient to get the drug was found to be 274.22 Kyats. Among the cost items, drug cost was the highest item that they had used.

A comparative study of intervention methods (full, partial and non-integration) on late case detection and treatment irregularity in Yangon, Myanmar.

The high percentage (20%) of new cases with grade 2 disabilities, and a low treatment regularity of 47% indicated problems in case detection and case holding in Urban Yangon. The fact that Urban Health Centers (UHCs) were not involved in leprosy control programme might have had an adverse influence. To compare the effectiveness of two methods of integration (full and partial) of urban leprosy services in terms of early case detection and regularity of treatment this study was conducted, in an urban area. Two townships with similar leprosy prevalence, staff infrastructure, socio-economic status, transport, communication and working capacity of the Township Medical Officers (TMOs) were chosen for this intervention study: UHC-A(Thingangyun) for full integration and UHC-B(Tamwe) for partial integration and the remaining 14 townships as non-integrated areas served by the Central Special Skin Clinic (CSSC). This study has shown that it was possible to fully integrate Leprosy Control Programme (LCP) into the Urban Health Centres [Basic Health Services (BHS)] in Urban Yangon. Case detection could be improved by active case finding such as contact examination and school examination conducted by the personnel of UHCs. Treatment regularity was found to be directly proportional to prompt defaulter retrieval action and the motivational level of the TMO and peripheral BHS workers. There were more complaints from patients (8.1%) treated at UHC-A when compared to CSSC (6.7%). Among defaulters there were more adults than children, more males than females and more PB than MB patients.

Serum cortisol levels in patients with uncomplicated and cerebral malaria.

Ten patients with uncomplicated malaria, ten with cerebral malaria and 37 controls (blood donors from blood bank) were included in the study. The serum cortisol levels of the patients were determined daily for 7 days while they were at the hospital. A radio-immunoassay method was used for quantitative measurement of cortisol in human serum. The mean serum cortisol level of patients with uncomplicated malaria was 528.2 +/- 123.9 nmol/l, with cerebral malaria was 516.0 +/- 80.5 nmol/l, and in controls was 393.8 +/- 141.0 nmol/l. There was a significant rise of serum cortisol levels in patients with malaria when compared to controls at the day of admission to hospital. There was no significant difference between uncomplicated malaria patients and those with cerebral malaria. There was also no significant difference between the different days of treatment up till day 7. We found no cortisol insufficiency in cases with falciparum malaria during acute and convalescent stages of illness.

Prevalence of colour blindness among patients with leprosy.

Using Ishihara test plates the prevalence of colour blindness was studied on six hundred and ninety-seven leprosy patients and two hundred and ninety-two normal healthy controls. 7.88% of male patients with tuberculoid leprosy, 12.18% of male patients with lepromatous leprosy, and 0.67% of male controls were detected to be colour blind (red-green deficiency or total colour weakness). The differences between the different groups are significant. Among female patients and controls, only one lepromatous leprosy patient was detected to have red-green deficiency. This suggests the possibility of a genetic predisposition to Mycobacterium leprae infection in patients with leprosy.

The effect of artemether plus mefloquine on Myanmar patients with complicated falciparum malaria.

The effect of artemether plus mefloquine versus quinine on 35 patients with complicated falciparum malaria including 5 patients with cerebral malaria were studied. All patients treated with the artemether-mefloquine combination survived and all were free from toxic effects of the drugs. Three patients on quinine therapy died. The mortality rate was 8.5%. The mean parasite clearance time of patients treated with artemether plus mefloquine was significantly shorter than those treated with quinine but there was no significant difference in the mean fever clearance of the two groups of patients. There was no recrudescence with artemether and mefloquine; the recrudescence rate was 5.5% with quinine. The study showed that the artemether-mefloquine combination is superior to quinine for the treatment of patients with complicated falciparum malaria, including cerebral malaria.

The effect of tetanus toxoid in leprosy patients.

Since cases of lepra reaction following smallpox vaccination and BCG vaccination had been reported the effect of tetanus immunisation on leprosy patients (whether it may provoke a lepra reaction or not) was studied. Three doses of purified tetanus toxoid (one ml initially, one ml after six weeks and one ml after six months) were given to 357 leprosy patients and 60 patients living in the same environ were followed as controls. The antibody response following immunisation was followed in six lepromatous leprosy patients using toxin antitoxin neutralisation test at the Lf/1000 level in mice and in three of them the antibody titre of leprosy patients rose to satisfactory level. The number of lepra reactions in these patients was monitored for nine months (two months before vaccination, during the six months period of vaccination and one month after the last dose of vaccine). There was no significant rise in the number of patients with reaction following the vaccination.

The effect of mefloquine-sulfadoxine-pyrimethamine vs quinine on patients with complicated falciparum malaria.

Sixty-six patients with complicated falciparum malaria (defined as anaemia, hyperpyrexia, jaundice, or more than 2% of RBC parasitised) were studied. Patients with cerebral signs and symptoms were not included in the study. Patients were randomised in pairs to receive either mefloquine 750 mg, sulfadoxine 1500 mg and pyrimethamine 75 mg (MSP) single oral dose or quinine (10 mg/kg tds X 7 days oral therapy). All the patients were admitted in hospital for 7 days and were followed on days 14, 21 and 28. All patients survived. The parasite clearance times in MSP treated patients were significantly shorter then those treated with quinine. There was no difference in fever clearance time in the two groups of patients. One patient was resistant to MSP at RII level and 5 patients were resistant at RI level. Among patients treated with quinine 3 patients were resistant at RI level.

Hydrocortisone in the management of dengue shock syndrome.

A total of 98 patients with dengue shock syndrome admitted into Children's Hospital from February 1973 to February 1974 were randomly selected into 2 groups. A double blind controlled trial of the efficacy of pharmacologic doses of hydrocortisone hemisuccinate was carried out. The 2 groups were confirmed to be completely matched by age, sex and severity of the disease. Nine deaths occurred out of 48 cases in the steroid group (Case Fatality Rate 18.75%) and 22 deaths out of 50 cases in the non-steroid group (Case Fatality Rate 44%), the difference being statistically significant. No significant difference was detected in fluid requirements and other morbidity pattern.
