Nutritional status of rural children in the Lesotho Highlands.

A baseline cross-sectional study was done to evaluate the nutritional status of the population of the Mohale Dam catchment area before construction of the dam commenced. In this article we report on the anthropometric, clinical and dietary assessment of the children less than 15 years of age in the study population. A two stage stratified sampling technique was used to randomly select 29 of the 83 villages in the study area. Children under 15 years of age from 395 households, representing approximately 50% of households in the selected villages, were included in the study. Anthropometric measurements of body height and weight in relation to age and sex indicated undernutrition varying, with few exceptions, from high to very high levels in children under 15 years. Stunting, indicating chronic undernutrition, was of particular concern in children, even from the first year of life. Very few clinical signs of nutritional deficiencies were found except for a goitre prevalence of 17.5% in 10 to 14 year old children. This was supported by the very low urinary iodine excretion (median 1.3 micrograms/dL) which indicated a severe iodine deficiency. Dietary evaluation showed high initiation rates of breastfeeding as well as a long duration of breastfeeding. Complementary foods were introduced at an early age, resulting in low exclusive breastfeeding rates. Regular meals were reported but qualitative analysis of the diet showed that a too small variety of foods were eaten, with an irregular intake of protein-rich foods and milk. Quantitative data on 3- < 5-year-old children showed that micro-nutrient intakes were low and that the energy intake of these children was inadequate. The results showed that these nutritionally vulnerable children should be monitored for the impact of the dam construction on their nutritional status.

Laparoscopic diagnosis of ascites in Lesotho.

In a prospective study of 98 consecutive patients with undiagnosed ascites examined by laparoscopy a correct immediate diagnosis was made in 76 (78%) and a final diagnosis in 92 (94%) of those who underwent laparoscopy. Visual diagnosis was highly accurate in patients with tuberculous peritonitis but only moderately accurate in those with carcinomatosis and liver disease. When the laparoscopic findings were compared with histological and microbiological results visual diagnosis was found to be the most accurate diagnostic method. Laparoscopy may readily be used in rural hospitals for diagnosing ascites.

Cancrum oris in HIV infected children in Lesotho: report of two cases.

Cancrum Oris (Noma) has been known to mankind since time immemorial. Its public health importance is lately being realised especially in Africa, where majority of the cases occur. It affects those whose immune systems are compromised and thus, it is no wonder that it is being reported in HIV infected individuals. This development could have serious implications regarding the impact of the HIV pandemic globally and in particular the African region where poverty is rife.

Oral HIV lesions and oral health behaviour of HIV-positive patients attending the Queen Elizabeth II Hospital, Maseru, Lesotho.

AIM: The aim of the study was to determine the prevalence of oral mucosal lesions strongly associated with HIV infection and to assess the oral health behaviour among patients attending Queen Elizabeth II Hospital in Maseru. The objectives were: (i) to determine the prevalence of group 1 lesions in HIV-positive patients according to the ECC/WHO classification; (ii) assess the oral hygiene practices of these patients; and (iii) make recommendations based on the findings. METHODOLOGY: A questionnaire was administered by an interviewer to a sample of 270 patients with a serological diagnosis of HIV infection to assess their oral health behaviour; they were then examined for oral manifestations. The assessment of oral health behaviour involved determining the regularity and frequency of oral hygiene practices, and use of mouth wash, interdental and other adjunct cleaning aids. The presumptive criteria as defined by the ECC/WHO classification were used for diagnosis of the oral mucosal lesions. Results were entered and analysed using Epi info-6 statistical software RESULTS: The prevalence of specific oral mucosal lesions in order of occurrence was pseudomembranous candidiasis 27%, erythematous candidiasis 26%, angular cheilitis 14%, hairy leukoplakia 12%, ulcerations 12%, necrotising gingivitis 5%, linear gingival erythema 3%, and non-Hodgkin's lymphoma and Kaposi's sarcoma less than 1%. This pattern reflects the findings in other regional studies where pseudomembranous candidiasis is often the most common lesion found. Nearly all patients reported cleaning their mouths; 82% did it every day. Mouth wash and interdental cleaning aids were not often used. CONCLUSIONS: A high prevalence (73%) of oral mucosal lesions was found. Oral candidiasis was the most common group of lesions (54%). The oral hygiene practices reported by the patients were considered acceptable.

Human immunodeficiency virus seroprevalence in an occupational cohort in a South African community.

BACKGROUND: In the early years of the worldwide pandemic, there were no reported cases of acquired immunodeficiency syndrome in Lesotho, a small, mountainous country in South Africa. Since 1986, when the first case of acquired immunodeficiency syndrome was identified, reported diagnoses have risen precipitously. The initiation of the Lesotho Highlands Water Project has resulted in the influx of a migrant workforce of predominantly single males into a relatively isolated, mountainous area where human immunodeficiency virus (HIV) was previously unknown. OBJECTIVE: To ascertain the HIV seroprevalence among a cohort of laborers at the Katse Dam construction site in Bokong, Lesotho. METHODS: During the 5-week study period in late 1992, construction workers (age range, 15 to 59 years) who were first-time clinic users for any chief complaint were randomly selected for serological study. Surveillance complied with the Lesotho National AIDS Control Programme guidelines, which required unlinked, anonymous testing. Serum samples were screened by an enzyme-linked immunosorbent assay; the results were confirmed by the Western blot technique. RESULTS: Unlinked, anonymous HIV testing of 486 persons revealed a seroprevalence of 5.3% (26/486; 95% confidence interval, 3.3% to 7.3%). These data contrasted with a 0.8% seroprevalence in a similar age group in nearby villages that surrounded the construction project. CONCLUSIONS: Lesotho, in the early phase of the HIV/acquired immunodeficiency syndrome epidemic in Africa in the 1980s, was seemingly protected by its relative isolation. Grave concern is now warranted as the country is destined to experience a rapid rise in HIV seroprevalence. Increased surveillance, health education opportunities, and aggressive prevention activities at the Katse Dam construction site are imperative to arrest the spread of HIV from construction workers to nearby villagers.

Monitoring of water transfer from Katse Dam into the Upper Vaal river system: water utility's perspective.

Water quality is of prime importance to Rand Water's core business of ensuring a reliable supply of good quality drinking water to more than 10 million people. Rand Water has, therefore, implemented a water quality monitoring programme of the source water as well as the drinking water produced. The establishment of the Lesotho Highlands Water Transfer scheme necessitated the expansion of the monitoring programme. In 1996, Rand Water and Lesotho Highlands Development Authority (LHDA) signed an agreement to jointly develop an extensive water quality monitoring programme for the Lesotho Highlands Water Project (LHWP). Prior to this agreement, monitoring was mainly undertaken by consultants on behalf of LHDA in the main feeder rivers within the Katse Dam catchment (donor system). On the recipient system (Ash/Liebenbergsvlei), extensive physical and chemical monitoring was undertaken by Rand Water and Department of Water Affairs and Forestry (DWAF). Biological monitoring was however only carried out superficially prior to the release of water. Information gained from carrying out biological and chemical assessments clearly indicates that the water from LHWP has negatively impacted on the biological communities in the recipient system. The importance of detailed before and after biological and physiochemical monitoring of both donor and recipient systems is emphasised.
