Abstractobjectives To describe the characteristics of suicide and assess the capacity of health services at the district level in Cameroon to deliver quality mental health care.methods The study covered the period between 1999 and 2008 and was carried out in Guidiguis health district which had a population of 145 700 inhabitants in 2008. Data collection was based on psychological autopsy methods. To collect data, we used documentary review of medical archives, semi-structured interviews of relatives of suicide completers, a focus group discussion of health committee members and a survey to consulting nurses working at the primary health care level.
Loiasis is a neglected disease that may have great social and economic impact in some endemic areas. This study was designed to update the geographical distribution of loiasis and assess the frequency and perceptions of the clinical signs of the disease in the Eastern province of Cameroon. The investigation covered 32 villages and involved 4146 respondents. Human infection with Loa loa was endemic in all the study villages but the prevalence of microfilaraemia generally decreased from south to north. All of the study villages had local names for eye worm and Calabar swellings that varied in meaning and among the various ethnic groups. The most common traditional treatment for eye worm was garlic or onion juice, which is dripped into the affected eye. The body sites that were most affected by Calabar swellings were the upper (30%) or lower (32%) limbs. The swellings were very painful (46%), mildly painful (28%) or painless (26%). Most respondents (94%) reported that the swellings itched. The prevalence of L. loa microfilaraemia in most of the study villages was >20%. These villages are clearly at risk of severe adverse events, with encephalopathy, following mass distribution of ivermectin. The prevalence of the main clinical manifestations of loiasis (i.e. eye worm and/or Calabar swellings) was twice that of detectable microfilaraemia.
Summaryobjective To explore the interface between vertical programmes (VPs) and general health services (GHS) in sub-Saharan Africa.methods Using semi-structured interviews, we analysed the perceptions of a selection of experienced mid-level managers of GHS and of VP originating from francophone Africa on the nature and quality of this interface.results The respondents acknowledged that VPs lead to both positive and negative effects on the functioning of GHS. The overall result, however, cannot be viewed as a simple summation of the positive effects possibly compensating for the negative ones. Indeed, some of the negative effects have a profound impact on the management and operation of the health care delivery system and may undermine the long-term institutional capacity of the general health systems. The quality and the nature of the interface between VP and GHS strongly vary in time, between settings and programmes.conclusion We argue for more systematic monitoring of the interface between VP and GHS, so as to identify and address, in a timely manner, significant disruptive effects and deficiencies in a perspective of systemic capacity building of health systems.keywords vertical programme, general health service, interface, sub-Saharan Africa
Although field trials of the application of molluscicides for the control of human schistosomiasis have been conducted in several settings, the acceptability of molluscide use at the community level has been poorly documented. The death and putrefaction of aquatic organisms in water treated with niclosamide (Bayluscide), for example, and the yellowish colouration of such water, may decrease the molluscide's acceptability. It may be possible, however, to use doses of a molluscicide that are only just high enough to kill the target snails but not high enough to kill non-target fish and frogs, thereby reducing the application's impact on water quality and colour and improving its acceptability to local communities. In a study in northern Cameroon, Bayluscide WP70 was applied to ponds at concentrations of 0, 0.25, 0.5 or 1 g/m(3). Changes in human contact with the water in the ponds were explored both by direct observation and by in-depth interviews with key informants from the local community. Although all applications of niclosamide greatly decreased human use of the treated ponds for a few days, most informants (99%) were in favour of niclosamide application and only 6% of the interviewees gave change in water colour or bad smell as a reason for not using a particular water body. Over the few days post-application, use of ponds treated with 0.25 or 0.5 g Bayluscide WP70/m(3) was higher than that of the ponds treated with 1 g/m(3), indicating that relatively low-dose applications, if effective in controlling snails, may be more acceptable to local communities than applications at higher doses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
