Point-of-use water treatment and diarrhoea reduction in the emergency context: an effectiveness trial in Liberia.
Communicable diseases are of particular concern in conflict and disaster-affected populations that reside in camp settings. In the acute emergency phase, diarrhoeal diseases have accounted for more than 40% of deaths among camp residents. ⋯ In intervention households, point-of-use water treatment with the flocculant-disinfectant plus improved storage reduced diarrhoea incidence by 90% and prevalence by 83%, when compared with control households with improved water storage alone. Among the intervention group, residual chlorine levels met or exceeded Sphere standards in 85% (95% CI: 83.1-86.8) of observations with a 95% compliance rate.

Thresholds for health insurance in Rwanda: who should pay how much?
Community-based health insurance schemes were introduced in Rwanda in 1999 and now cover 27% of the population. Due to widespread poverty, it remains unclear to what degree poorer population strata can be anticipated to pay into the system. This study investigates the extent to which the Rwandan population can financially contribute to obtain health insurance. ⋯ Data from six household surveys are analysed revealing a consistent pattern: the goals of maximizing health revenue and maximizing participation in community-based health insurance are mutually exclusive. However, the upper three quartiles of the Rwandan population are able to contribute 1 US dollar per capita per year. In order to extend coverage to the poorest quartile, a corresponding subsidy for the coming years has to be considered.

Relationship between haemoglobin and haematocrit in the definition of anaemia.
Anaemia is the most frequent haematological disorder in childhood. The notion that defines naemia does not change throughout life, although parameters used for its evaluation show significant variations during childhood. Haematocrit (Hct) (%) is usually defined as three times the value of haemoglobin (Hgb) (g/dl), while the clinical definition of anaemia is related to either an abnormal Hct or Hgb value. ⋯ Measurement of haematocrit count is easy and can be performed in most rural health care centres. However, the corresponding Hgb levels cannot be derived with an acceptable accuracy using the value 3 as a conversion factor. Furthermore, the commonly assumed 'equivalent' cut-off points for anaemia definitions need to be re-evaluated.

Review Meta Analysis Comparative StudyIntrathecal vs. intramuscular administration of human antitetanus immunoglobulin or equine tetanus antitoxin in the treatment of tetanus: a meta-analysis.
Mortality caused by tetanus is still a serious health problem in developing countries. Apart from immunization, early treatment with equine antitetanus serum (ATS) or human tetanus immunoglobulin (TIG) is the real treatment that can avoid death. On pathophysiological grounds intrathecal administration would be preferred because of high concentrations of the antiserum in cerebrospinal fluid and thus around the nerve roots. Many studies concluded on its effectiveness whereas others did not find any superiority of this method. However, most of those studies were not random and/or had no sufficient weight. ⋯ A total of 942 patients were included in 12 trials, 484 in the intrathecal group and 458 in the intramuscular one. The combined RR of mortality for intrathecal vs. IMS was 0.71 (95% CI, 0.62-0.81). The superiority of intrathecal therapy also emerged when the analysis was performed in subcategories of both adults and neonates and for high and low dose of intrathecal serotherapy. Intrathecal administration of ATS or TIG is more beneficial than intramuscular administration in the treatment of tetanus.
