Deliberate self-harm is an important problem in the developing world. Ingestion of yellow oleander seeds (Thevetia peruviana) has recently become a popular method of self-harm in northern Sri Lanka -- there are now thousands of cases each year. These seeds contain cardiac glycosides that cause vomiting, dizziness, and cardiac dysrhythmias such as conduction block affecting the sinus and AV nodes. This paper reports a study of the condition's mortality and morbidity conducted in 1995 in Anuradhapura General Hospital, a secondary referral centre serving 750 000 people in Sri Lanka's north central province. 415 cases were admitted to the hospital during 11 months; 61% were women and 46% were less than 21 years old. A prospective study of 79 patients showed that 6% died soon after admission. 43% presented with marked cardiac dysrhythmias which necessitated ther transfer to the coronary care unit in Colombo for prophylactic temporary cardiac pacing. The reasons for the acts of self-harm were often relatively trivial, particularly in children; most denied that they wished to die. Unfortunately, the case fatality rate for oleander poisoning in Sri Lanka is at least 10%. This epidemic is not only causing many unnecessary deaths, it is also putting immense stress on the already stretched Sri Lankan health services. There is an urgent need for an intervention which could be used in rural hospitals, thus preventing the hazardous and expensive emergency transfer of patients to the capital.

This study presents findings on the socio-demographic and health characteristics, continuation rates, menstrual disturbances, and changes in menstrual patterns as well as other side effects among a sample of 952 1st time acceptors of the injectable contraceptive Depo-Provera during 1978-1980 in Colombo, Sri Lanka. Those continuing to use the method were observed for 24 months. The reasons for discontinuation are discussed based on another study that focused on 321 discontinuers who received Depo-Provera from the same clinic. The overall continuation rates at 12 and 24 months were 58% and 29%, respectively. Relatively older and higher parity women had lower continuation rates than younger and lower parity women. The occurrence of amenorrhea rose sharply foloowing the 1st dose and stabilized such that about 1/3 of those continuing with Depo-Provera became amenorrheic. 1/4 of the women experienced menstrual disturbances such as spotting and irregular bleeding. Other side effects, including vomiting, headache, and dizziness, affected 6% of the women following the 1st dose, but declined gradually over time. Over the course of the observation, 41-66% of the women appeared to gain weight. The 2 primary reasons for discontinuing Depo-Provera were non-medical: 1) the desire to have another child and 2) the decision to be sterilized. The findings suggest that Depo-Provera has played a signinficant role in Sri Lanka in 2 ways: 1) its use has provided desired pregnancy spacing for those who wished to have another child and 2) it has assisted couples by providing them with time (without the fear of pregnancy) to decide to stop having children and then get sterilized.

This study assesses the nutritional status of tuberculosis (TB) patients in Sri Lanka and differences in the nutritional presentation between males and females. In May-June 2002, cases from Colombo hospitals and controls from both the Sri Lankan Air Force Base and audience members at a 'better health' presentation in Colombo were assessed for nutritional status using a modified Standard Global Assessment. Fifty cases and 49 controls were recruited. Nutritional examinations revealed the cases to have significantly lower nutritional values than the controls (body mass index 16.2 vs. 24.0 kg/m(2); arm circumference 20.7 vs. 28.4 cm; muscle wasting [temple 56% vs. 0%; shoulder 46% vs. 0%]). The nutritional history revealed the cases to have higher levels of anorexia, vomiting, nausea and diarrhoea within the preceding fortnight. Differences between the genders were minimal other than an increase of 23 and 19% in the frequency of female cases having suffered with vomiting and nausea respectively. Consequently, both male and female TB patients in Sri Lanka are significantly malnourished. It is recommended that patients receive nutritional support during their treatment, with studies of the exact nutritional deficiencies at the micronutrient level and their effect on the immune system being required.

We aimed to identify clinical features that would be useful for case detection and the appropriate timing of investigations and hospital admissions in patients with short-duration fever, suspected to be dengue fever (DF). Of 928 adult patients with short-duration fever admitted to Colombo North Teaching Hospital, Sri Lanka during February-June 2004, one in four were randomly selected for assessment of the severity of six clinical features: headache, body aches, vomiting, retro-orbital pain, generalised weakness (scale 0-9) and skin erythema (grade 1-5). There were 148 DF patients (95 males, mean age+/-SD: 28+/-12 years) and 54 non-DF patients as controls (44 males, mean age+/-SD: 25+/-11 years). All symptoms assessed (cut-off >or=5) and skin erythema (>or=grade 2) had a good positive predictive value for DF. However, erythema had the best negative predictive value, helping to differentiate DF from other short-duration fevers. More than 95% of patients with dengue had a platelet count above 50000/microl until the third day of illness. The platelet counts were significantly reduced when erythema, fever, vomiting and generalised weakness were persistent. In conclusion, erythema elicited by hand impression may help in the prediction of DF, and follow-up blood counts are indicated when symptoms persist.
