    Introduction Intestinal parasites are more common in people with HIV, especially in tropical developing countries. This cross-sectional study was carried out to assess the prevalence of intestinal parasites among people with HIV at the Yaoundé Central Hospital Accredited Treatment Centre. Methods Structured questionnaires were used to collect clinical information after obtaining consent from the participants. Stool samples were collected from 207 HIV-positive patients for the investigation of intestinal pathogens using direct microscopy, formalin-ether concentration, ZiehlNeelsen modified and Kato-Katz methods. Data was analyzed using Epi-info version 3.4.1. and Microsoft Office Excel 2007. Results A total of 207 people were recruited. Eighty (38.65%) were male and 127 (61.35%) were female. The overall prevalence of intestinal parasite infections was 57.48% (119/207). The parasites detected in our study population included Entamoeba coli (22.68%), Ascaris lumbricoïdes (22.68%), Entamoeba histolytica(15.93%), Cryptosporidium spp (12.60%), Isospora belli (10.08%), Trichuris trichiura (7.60%), Strongyloïdesstercoralis (5.88%), Ancylostomaduodenale and Necatoramericanus (2.52%). Conclusion At the end of our study, it appears that intestinal parasites still occupy an important place among HIV-positive patients. PMID:25419274

    Data on the prevalence and complications of gestational diabetes are very scarce in Cameroon. The aim of this study was to evaluate the uptake of screening for gestational diabetes and assess the immediate post-partum outcome of hyperglycemic parturient mothers and perinatal outcome of their babies. A prospective cohort study was held at the Maternity of the Yaoundé Central Hospital from March to June 2013. One hundred volunteer women in labor without overt diabetes mellitus and having fasted for 8 to 12 h were recruited. No intervention was given. A clinical examination was done and capillary glucose recorded. Parturient women were categorized into two groups (hyperglycemic and non-hyperglycemic subjects) based on glycemia results interpreted according to the International Association of Diabetes and Pregnancy Study Groups. Mothers' clinical examination was repeated and neonates examined immediately after delivery. Perinatal outcomes associated with maternal hyperglycemia during labor were assessed using relative risks. A p value <0.05 was considered statistically significant. One hundred women with a mean age of 27 (SD 6) years were recruited. Of them, 22 (22 %) had already been screened for gestational diabetes at baseline. Thirty-one (31 %) were diagnosed with hyperglycemia during labor, and this condition was highly associated with macrosomia in neonates (RR = 8.9, 95 % CI 2.70-29.32; p < 0.001). Other complications associated with maternal hyperglycemia during labor were perineal tears, cesarean section, and intrauterine fetal death, though the association was not statistically significant. The main finding of this study is that maternal hyperglycemia during labor is highly associated with macrosomia in neonates. About a third of mothers were concerned with hyperglycemia during labor, and gestational diabetes was insufficiently screened in this series.

    From April 1988 to March 1989, 903 randomly chosen children were examined in the Maternal and Child Health Department of the Central Hospital of Yaounde (Cameroon) to determine the importance of malaria in general morbidity, the relation between clinical symptoms and parasite densities and to have some idea of the population's self-medication behaviour. We adopted the criteria formerly worked out in West Africa, i.e. a fever (t degree higher than 37.9 degrees C) without any obvious febrile disease and a parasitaemia higher than 10,000 red blood cells parasitized by Plasmodium falciparum/mm3. In the sample under investigation, the average plasmodic index was 32.5%, mainly P. falciparum (98% of all infections), while 120 children had a parasitaemia higher than the critical level of 10,000 par./mm3 (i.e. 13.3% of the whole sample and 40.1% of Plasmodium carriers. 559 of the 903 children were actually febrile and among them 94 had a so-called malaria crisis (i.e. 16.8% of fevers and 10.4% of all consultations). It was confirmed that not one single clinical symptom is pathognomic for malaria crisis but fever, splenomegaly and anaemia seemed to occur more frequently among sick children. It also appeared that the proportion of children with fever increased as their parasitaemia exceeded the critical threshold of 10,000 par./mm3, while splenomegaly tends to drop with very high parasitaemia. Faced with fever as a clinical symptom, self-medication is a common behaviour (65% of people interviewed admitted such practice); it is mainly based upon chloroquine tablet ingestion but at a subcurative dosage. Such self-medication could induce an underestimation of malaria morbidity from clinical statistics and, on the other hand, a growing drug pressure, which could play a role in the current spread of P. falciparum chloroquine resistant strains in Central Africa and elsewhere in sub-saharan regions.

    Introduction Many studies still show significant numbers of surgical patients contracting nosocomial infections each year globally with high morbidity and mortality. The aim of this study was to identify potential bacteria reservoirs that may be responsible for nosocomial infection in surgical services in the Yaoundé University Teaching Hospital (YUTH) and the Central Hospital Yaoundé (CHY). Methods A cross sectional descriptive study was conducted from June to August 2012. Air, water, and surface samples were collected from two surgical services and subjected to standard bacteriological analysis. Results A total of 143 surface samples were collected. Bacteria were isolated in all surfaces except from one trolley sample and a surgical cabinet sample. The predominant species in all services was coagulase negative Staphylococcus (CNS). The average number of colonies was 132. 82CFU/25cm2. The bacteria isolated in the air were similar to those isolated from surfaces. From the 16 water samples cultured, an average of 50.93 CFU/100ml bacteria were isolated. The distribution of isolated species showed a predominance of Burkholderia cepacia. Conclusion These results showed the importance of the hospital environment as a potential reservoir and source of nosocomial infections amongst surgical patient at YUTH and CHY, thus we suggest that Public health policy makers in Cameroon must define, publish guidelines and recommendations for monitoring environmental microbiota in health facilities.

    Background: very little is known about musculoskeletal features of multiple myeloma (MM) in Africa. To describe the musculoskeletal features of multiple myeloma at presentation in a tertiary health care centre in sub-Saharan Africa. A Cross sectional observational study. The Douala General Hospital, Cameroon from 2007 to 2013. A patient was said to have MM according the current international consensus criteria for diagnosis and staging of MM. Patients with monoclonal gammopathy of undetermined significance, solitary plamocytoma and other haematologic malignancies were excluded. A total of 62 patients were diagnosed with multiple myeloma, 63% were female. Mean age was 57 ± 12,1 (19-81) years. Musculoskeletal presentation included spine bone pains (75.6%); vertebral fracture with spinal cord compression in 46.8 %. Other clinical features at presentation included anaemia (70.93%), and nephropathy (17.74%). The average percentage of bone marrow plasmacytosis at diagnosis was 33% and Immunoglobulin G was found in 86% of patients. Sixty three per cent of patients were diagnosed at stage III of the disease. Presence of bone pain and anaemia should alert the clinician to investigate along the lines of multiple myeloma. Majority of the patients have osteolytic lesions and pathologic fractures at the time of diagnosis.

    In most parts of the world, ticks are rapidly developing resistance to commonly used acaricides thus rendering control difficult. This constraint is further compounded by the introduction of new species in areas where they did not exist before. Such is the case with the introduction into and rapid spread of Rhipicephalus (Boophilus) microplus in some countries of West Africa. With the looming threat of its further spread in the region, the objective of the present study was to update knowledge on cattle ticks in Cameroon. Among 19,189 ticks collected monthly from 60 animals in 5 herds from March 2012 to February 2013, Rh. (B.) decoloratus was the most abundant species with a relative prevalence of 62.2%, followed by Amblyomma variegatum (28.4%), Rh. (B.) annulatus (0.2%), Rh. (B.) geigyi (0.03%), other Rhipicephalus spp. (8.4%) and Hyalomma spp. (0.3%). Rh. (B.) decoloratus and A. variegatum were also the most widely distributed in space. Infestation rate was generally high, with average tick count/animal of about 80 during peak periods. Tick distribution and abundance in the different sites was as varied as the underlying factors, among which the most important were management systems and climatic factors. The effects of rainfall and temperature were confounded by other factors and difficult to evaluate. However, it appears tick development depends among other factors, on a humidity threshold, above which there is not much more effect. Rh. microplus was not found during this study, but more extensive tick collections have to be done to confirm this. In conclusion, cattle tick infestation in Cameroon remains an important cause for concern. Farmers need assistance in the use and management of acaricides in order to increase their efficiency and reduce the development of resistance. Although Rh. microplus was not found, its introduction from other West African countries is imminent if adequate measures, especially in the control and limitation of animal movements

    More than 550,000 women die yearly from pregnancy-related causes. Fifty percent (50%) of the world estimate of maternal deaths occur in sub-Saharan Africa alone. There is insufficient information on the risk factors of maternal mortality in Cameroon. This study aimed at establishing causes and risk factors of maternal mortality. This was a case-control study from 1st January, 2006 to 31st December, 2010 after National Ethical Committee Approval. Cases were maternal deaths; controls were women who delivered normally. Maternal deaths were obtained from the delivery room registers and in-patient registers. Controls for each case were two normal deliveries following identified maternal deaths on the same day. Variables considered were socio-demographic and reproductive health characteristics. Epi Info 3.5.1 was used for analysis. The mean MMR was 287.5/100,000 live births. Causes of deaths were: postpartum hemorrhage (229.2%), unsafe abortion (25%), ectopic pregnancy (12.5%), hypertension in pregnancy (8.3%), malaria (8.3%), anemia (8.3%), heart disease (4.2%), and pneumonia (4.2%), and placenta praevia (4.2%). Ages ranged from 18 to 41 years, with a mean of 27.7 ± 5.14 years. Lack of antenatal care was a risk factor for maternal death (OR=78.33; CI: (8.66- 1802.51)). The mean MMR from 2006 to 2010 was 287.5/100,000 live births. Most of the causes of maternal deaths were preventable. Lack of antenatal care was a risk factor for maternal mortality.

Water samples were collected during the dry season on March 2013. Bacterial and archaeal communities were profiled using Polymerase Chain Reaction-Denaturing Gradient Gel Electrophoresis (PCR-DGGE) approach of the 16S rRNA gene. The results indicate a stratification of both communities along the water column. Altogether, the physico-chemical data and microbial sequences suggest a close correspondence of the potential microbial functions to the physico-chemical pattern of the lake. We also obtained evidence of a rich microbial diversity likely to include several novel microorganisms of environmental importance in the large unexplored microbial reservoir of Lake Nyos.

    Background Severe acute malnutrition (SAM) is a major health problem, and the cause of more than half of childhood deaths in children less than 5 years in developing countries. Globally, 20 million children under 5 years of age are severely malnourished according to the World Health Organization (WHO). In Cameroon, the prevalence of SAM remains high and estimated at 1.9% in 2011 and 1.3% in 2014. The aim of this study was to determine the epidemiology, clinical aspects and outcome of SAM at the Yaounde Gynaeco-Obstetric and Pediatric Hospital (YGOPH). Methods We retrospectively reviewed the medical records of children hospitalized in the YGOPH for SAM over a period of 8 1/2 years (from September 2006 to March 2015). We included the medical records of children under 15 years of age who were hospitalized in the pediatric unit of the YGOPH for the management of SAM. Data was collected using a data entry form and was analyzed with Epi info version 3.5.4 software. Data was considered statistically significant for P less than 0.05. Results The prevalence of SAM was 2.72%. The median age was 9 months (range, 23 days–112 months). The most represented age group was 6 to 12 months with 34.6% of the children. The most frequent symptoms on admission were: wasting (58.1%) and fever (53.6%). The mean interval between the onset of symptoms and admission was 30.36 days. Marasmus was the most frequent clinical form of SAM observed in 88.8% of the children. Respiratory tract infections were the most common comorbidities and were present in 45 patients (25.1%), followed by malaria in 15.1% of cases. The sero-prevalence of human immuno deficiency virus (HIV) was 43.75% amongst the 32 children whose HIV status was known. Dehydration was the most frequent complication, with an occurrence of 29.6%. A total of 58.7% of patients were discharged following clinical improvement and the mortality rate was 15%. The average duration of hospitalization was 8.25 days. Conclusions SAM is a

    Konzo is a spastic paraparesis of sudden onset, linked to the exclusive consumption of insufficiently processed bitter cassava as staple food combined with low protein intake. Around 60,000 refugees from the Central African Republic sought refuge in villages in eastern Cameroon between 2005 and 2007. Médecins Sans Frontières was providing nutritional and medical assistance in the villages affected by displacement. We describe cases of konzo seen at the mobile clinics organized in these villages. Basic information including demographic data, history and clinical presentation was recorded for each konzo patient. All patients were given nutritional supplements, and selected cases were referred for physiotherapy to a rehabilitation center. A total of 469 patients were diagnosed with konzo. The majority (80%) were refugees. Children and women of reproductive age predominated. Most of the patients developed symptoms after 2007 in a seasonal pattern with most of the cases occurring during the dry winter season. Most of the patients complained about walking difficulties and weight loss and had exaggerated lower limb reflexes and muscle wasting on observation. Eastern Cameroon is an area with konzo. More effort needs to be put into preventive and educational measures. In addition, timely balanced food rations have to be provided to refugees.

    Nosocomial infections (NI) represent a real public health problem in developing countries. Their surveillance is recommended to provide needed information for better control. The aim of this study was to describe the frequency and distribution of NI in the Yaoundé University Teaching Hospital (YUTH). It was a longitudinal and descriptive study targeting hospitalized patients in the intensive care, gynaecological, surgical and neonatal units. Each consenting patient was administered a questionnaire at the beginning of the study and followed up daily for the duration of their hospitalization using a standardized grid to detect all nosocomial infections. Cumulative incidence was used to estimate NI frequency. There were 307 patients included. The cumulative incidence and specific mortality rate of NI were 19.21% (16.9-21.5) and 28% (16.2-42.5) respectively. Septicaemia (20.34%), infection of the skin and soft tissues (20.34%) and urinary tract infections (15.25%) were the most frequent type of NI. Klebsiella spp. was the most frequently isolated bacterium (27%). Nosocomial infections contribute to high hospital morbidity in the Yaounde University Teaching Hospital. Strategies need to be identified for a sustainable and continuous monitoring of NI in all health facilities of Cameroon. In addition, Further studies should identify NI determinants and interventions for efficient and better control.

    The DNA sequence of the dihydrofolate reductase (dhfr) gene, a molecular marker for pyrimethamine resistance, was determined for 178 field isolates of Plasmodium falciparum collected along the east-west axis in southern Cameroon. The proportion of isolates having the wild-type dhfr allele varied from 48.1% in the east (city of Bertoua) to 11.3-15.7% in central provinces (Yaounde and Eseka) and 0% in the littoral region (port city of Douala). Isolates with a single Asn-108 mutation or double mutations (Ile-51 or Arg-59 and Asn-108) constituted approximately 10% of the samples. Isolates with triple mutations (Ile-51, Arg-59, and Asn-108) were present in an equal proportion (48.1%) as the wild-type isolates in the east (Bertoua), while triple mutations predominated in Yaounde (62.3%), Eseka (62.7%), and Douala (78.9%). The distribution of triple dhfr mutations along the east-west axis in southern Cameroon suggests the presence of a decreasing gradient from the west coastal region to the central region and then to the east towards the interior of the country.

    Due to the infectious nature of some clinical waste, poor disposal practices have sparked concern regarding the impact on public health and the environment. Lack of sufficient knowledge of the associated risks may be a strong factor contributing to inadequate disposal practices. We conducted a survey to evaluate hospital workers' awareness of health and environmental impacts of poor clinical waste disposal in Cameroon. We randomly distributed 500 questionnaires to hospital workers in three hospitals in the Northwest Region of Cameroon in April 2008. In addition, we observed collection, segregation, transportation, and disposal of clinical waste at the three hospitals. Of 475 total respondents, most lacked sufficient awareness of any environmental or public health impacts of poor clinical waste disposal and had never heard of any policy--national or international--on safe clinical waste management. Methods of collecting, segregating, transporting and disposing clinical waste at the three hospitals was poor. The development of a comprehensive policy on efficient clinical waste management in Cameroon is imperative.

    Introduction: We performed an analytic and prospective study over a period of 12 months from January 2nd to December 31st, 2008, at the Gynaeco-Obstetric and Paediatric Hospital of Yaoundé, Cameroon. Our aim was to determine the prevalence and causes of unilateral blindness in school children aged 6 to 15 years. Results: Among the 1,266 children aged 6 to 15 years who were recruited, 60 presented with unilateral blindness (4.7%): 42 boys (6.96%) and 18 girls (2.71%). The mean age was 10.15 ± 3.4 years. In patients with unilateral blindness, 65% was due to ocular trauma. Discussion: The hospital-based prevalence of unilateral blindness in children is relatively high and ocular trauma is the leading etiology. Conclusion: Unilateral blindness in school children is avoidable and its incidence could be markedly reduced by emphasizing an information strategy and education based on prevention of ocular trauma. Early management of nontraumatic diseases such as infantile glaucoma and some tumors could improve outcome and avoid blindness. PMID:19714264

    Trauma is a leading cause of morbidity and mortality worldwide. Data characterizing the burden of trauma in Cameroon is limited. Regular, prospective injury surveillance can address the shortcomings of existing hospital administrative logs and medical records. This study aims to characterize trauma as seen at the emergency department (ED) of Limbe Regional Hospital (LRH) and assess the completeness of data obtained by a trauma registry. From January 2008 to October 2013, we prospectively captured data on injured patients using a strategically designed, context-relevant trauma registry instrument. Indicators around patient demographics, injury characteristics, delays in accessing care, and treatment outcomes were recorded. Descriptive, bivariate, and multivariate statistical analyses were conducted. About 5,617 patients, aged from 0.5-95years (median age of 26 years), visited the LRH ED with an injury; 67% were male. Students (27%) were the most affected occupation category. Road traffic injuries (RTIs) (56%), assault (22%), and domestic injuries (13%) were the leading causes of injury. Two-thirds of RTIs were motorcycle-related. Working in transportation (AOR 4.42, p<0.001) and law enforcement (AOR 1.73, p = 0.004) were significant predictors of having a RTI. The trauma registry showed a significant improvement in completeness of all data (p<0.001) and it improved over time compared with previous administrative records. However, proportions of missing data still ranged from 0.5% to 8.2% and involved respiratory rate or Glasgow Coma scale. Implementation of a context-appropriate trauma registry in resource-constrained settings is feasible. Providing valuable, high-quality data, the trauma registry can inform trauma care quality improvement efforts and policy development. Study findings indicate the need for injury prevention interventions and policies that will prioritize high-risks groups, such as those aged 20-29 years, and those in occupations requiring frequent

    Teenage pregnancy is a high-risk condition that requires skilled antenatal care for good outcome. World estimates in 2008 report about 16 million births to adolescent mothers, most of them occurring in low and middle-income countries. In Cameroon, about 12% of all births are to adolescent mothers. This study determines the prevalence of hospital teenage deliveries in the Buea Health District and compares the delivery outcomes and demographic characteristics between pregnant teenage mothers (14-19) and adult mothers (20-29 years). We also identify factors associated with adverse pregnancy outcomes. We undertook a retrospective study of case files of patients who gave birth in the Buea Regional Hospital during the period 2009-2012, to determine the prevalence of hospital-delivered teenage pregnancies in the BHR. We also undertook a, cross-sectional study to compare the outcomes of 148 singleton adolescent births with 360 adult births in three health facilities in the Buea Health District during the period March 1 to August 31, 2013. The prevalence of teenage births was 13.3%. The adverse fetal outcomes imputable to adolescent births were low birth weight (<2,500 g) (OR, 2.79; 95% CI, 1.28-6.09), preterm babies (<37 weeks) (OR: 1.85; 95% CI, 1.01-3.41), low 5 min Apgar score < 7 (OR: 1.66; 95% CI, 0.91-3.0). Adverse maternal outcomes associated with teenage pregnancies were mainly perineal tear (OR, 1.6; 95% CI, 0.95-2.7). Teenage births were not discovered in any significant way to cause preeclampsia/eclampsia, episiotomy, premature rupture of membranes and caesarean section. Maternal factors like age and gravidity were discovered to lead to adverse fetal outcomes in adolescents, while maternal factors like age, unemployment, marital status and gravidity were, for their part, directly responsible for adverse maternal outcomes in adolescents. Teenage pregnancies are quite prevalent in the Buea Health District, and hospital delivery common. Adolescent pregnancies

    The Ngaoundéré granite pluton, in Central-North Cameroon, located near the Central Cameroon Shear zone (CCSZ), and previously studied for its petrography and geochemistry, is characterized by the absence of macroscopic markers of deformation. In this study, we report microstructures and magnetic fabrics (AMS) of this pluton and discuss the relationship with the Pan-African evolution of the CCSZ. The pluton consists of a porphyritic Hbl-Bt-monzogranite at its rim and a porphyritic biotite-granite at its core, a petrographic distribution denoting a normal zoning pattern, i.e. more silicic toward the centre. As expected, magnetic susceptibilities values also exhibit a zoning pattern in agreement with petrographic zonation. Thermomagnetic data indicate that this pluton is dominantly ferromagnetic in behaviour. As indicated by its microstructures, the pluton has suffered a continuum of deformation from the magmatic state to the high temperature solid-state during magma crystallization and solidification. The magnetic foliations dominantly strike NE-SW and dip moderately to steeply and the lineations mostly plunge shallowly to the NE or SW, roughly parallel to NE-to ENE-trending Central Cameroun Shear Zone (CCSZ). The foliation poles define a girdle pattern with a zone axis (52°/11°) rather close to the best line of the lineations (44°/21°). These fabrics correlate with the structures of the country rocks ascribed by several workers to a regional transpression. Toward the margins of the pluton, particularly the northern one, the lineations tend to rotate from NE to N in azimuth. This change is interpreted as due to strain partitioning, simple shearing with NE-SW extension being relayed by compression toward the northern pluton border. This new magnetic fabric study suggests that the Ngaoundéré pluton (poorly dated at c. 575 Ma) was emplaced during the late stages of the CCSZ dextral transpressive movement. It also provides some more constraints on the correlation

    Genital mycoplasmas are implicated in pelvic inflammatory diseases, puerperal infection, septic abortions, low birth weight, nongonococcal urethritis and prostatitis as well as spontaneous abortion and infertility in women. There is paucity of data on colonisation of genital mycoplasma in women and their drug sensitivity patterns. The aim of our study was to determine the prevalence of genital mycoplasmas (Ureaplasma urealiticum and Mycoplasma hominis) infection and their drug sensitivity patterns in women. A mycofast kit was used for biochemical determination of mycoplasma infection in 100 randomly selected female patients aged 19–57 years, attending the University of Yaoundé Teaching Hospital (UYTH) from March to June 2010. Informed consent was sought and gained before samples were collected. Genital mycoplasmas were found in 65 patients (65%) [95% CI=55.7–74.3%] and distributed as 41 (41%) [95% CI=31.4–50.6%] for U. urealiticum and 4 (4%) [95% CI=0.20– 7.8%] for M. hominis while there was co-infection in 20 women (20%) [95% CI=12.16–27.84%]. In our study, 57 (57%) [95% CI=47.3–67%] had other organisms, which included C. albicans (19 [19%]), G. vaginalis (35 [35%]) and T. vaginalis (3 [3%]). Among the 65 women with genital mycoplasma, the highest co-infection was with G. vaginalis (33.8%). Pristinamycine was the most effective antibiotic (92%) and sulfamethoxazole the most resistant (8%) antibiotic to genital mycoplasmas. We conclude that genital mycoplasma is a problem in Cameroon and infected women should be treated together with their partners. PMID:28299057

    Abstract While conducting field inventories in South Cameroon, we collected two specimens of a new species that we considered to belong to the genus Angraecopsis. Afterwards, a careful examination of specimens housed at main herbaria, along with the nomenclatural types, allows us to place it in Distylodon, a monotypic genus previously known from East Africa. Distylodon sonkeanum Droissart, Stévart & P.J.Cribb, sp. nov. was collected in the lowland coastal forest of Atlantic Central Africa. It is known from a single locality in the surroundings of the Campo-Ma’an National Park. The species differs from D. comptum, by its several-flowered inflorescences, longer leaves and spur, and shorter pedicel and ovary. The species appears to be rare and is assessed as Critically Endangered [CR B2ab(iii)] according to IUCN Red List Categories and Criteria. New field investigations are required to attempt to find it in the low-elevation parts of the Campo-Ma’an National Park in Cameroon. PMID:24843291

    Hepatitis C virus (HCV) infection is a major public health problem, especially in resource-limited settings where many patients are diagnosed at the stage of complications. In Cameroon, where HCV is endemic, little is known about the clinical, biological, and virological profile of HCV-infected patients. A clinical case note review of all patients positive for antibodies against HCV diagnosed at the gastroenterology outpatient clinic of the Douala General Hospital, Cameroon, from January 2008 to December 2014, was performed. A total of 524 patients were included in the study, 53% of whom were female. The mean age was 56±13 years. A history of blood transfusion and a history of scarification were the most common potential risk factors for HCV exposure, as found in 16% and 13% of the study population, respectively. Current alcohol use was found in 24% of patients. Co-infection with hepatitis B virus and HIV was 3.6% and 3.4%, respectively. Among the patients, 39% had no complaint at diagnosis; only 16% were diagnosed through a routine medical checkup. Clinically, the most common finding was hepatomegaly (26.1% of patients). Transaminases above the upper limit of normal were found in 55.2% of patients, particularly those aged >57 years (p=0.001). Genotypes 1 (43.95%), 2 (25.11%), and 4 (28.25%) were the most common. Liver cirrhosis was present in 11% of patients and hepatocellular carcinoma in 4%, the latter being more common in males (p<0.001) and in those aged >57 years (p=0.03). In the gastroenterology clinic of Douala General Hospital, while almost 40% of patients who were anti-HCV antibody-positive were asymptomatic and diagnosed fortuitously, some already presented complications, including cirrhosis and hepatocellular carcinoma. There is an urgent need to put in place programs to increase awareness and diagnosis of HCV infection and to develop extensive and targeted anti-HCV treatment guidelines to improve the management of these patients in Cameroon.

    Injuries are a major cause of death and disability worldwide. Low-income countries, particularly in Africa, are disproportionately affected. The burden of injuries can be alleviated by preventive measures and appropriate management of injury cases. African countries generally lack trauma care systems based on reliable and affordable guidelines. The aim of this study was to assess the compliance of some district hospitals in Cameroon with World Health Organization/International Association for Trauma and Intensive Care (WHO/IATSIC) guidelines for care of the injured. This cross-sectional descriptive survey used items from the WHO/IATSIC "Guidelines for Essential Trauma Care" to develop a checklist for inspection of physical equipment and a questionnaire assessing human resources and organizational capabilities in 25 district hospitals of the Center Region of Cameroon. All hospitals surveyed had at least one doctor available. Each reported treating a mean of 338 ± 214 injury cases every year. Most hospitals (n = 22) were globally either not compliant or partly compliant with the guidelines. Staff generally had received the appropriate basic training but had no additional training specifically directed toward trauma management. Skills for managing specific injuries (e.g., chest injuries) were poor. Availability and utilization of equipment was globally inadequate, and organizational capabilities were almost nonexistent. District hospitals of the Center Region of Cameroon still lack compliance with the WHO/IATSIC guidelines for essential trauma care but have significant potential for improvement. It seems possible to optimize the utilization of existing facilities.

    This study aims to describe transfer modalities of newborn babies in vital distress to the ESSOS Hospital Center in Yaoundé, Cameroon. We conducted a prospective cross-sectional study from October 2014 to January 2015. Data were collected using a short questionnaire from the transfer operator. Main parameters: means of transport, reason for transfer, transfer delay, number of detours (itinerary before admission) prevalence for hypothermia, neonatal mortality rate. We recorded 73 transfers during the study period. Nearly 1/5 (22%) of infants were born within the health district of the reference structure. 24/73 newborns were referred for tertiary care centers (33%). The main reason for transfer was prematurity (40%) followed by neonatal asphyxia (26%). Medical transfer was performed in 5/73 (7%) cases, inter-hospital transfer effected through a nurse was performed in 10/73 (13.6%) cases. The average transfer time was 17 hours, 60% of babies were transferred within the first 6 hours of life, 22% (16/73) within the first two hours of life. For more than half of newborns, a transfer to another hospital was done before admission. Hypothermia (central temperature less than 36° C) on arrival was found in 20% of cases. 15/73 (20.5%) of transferred newborns died. The mean temperature in the dead infants upon their arrival to the hospital was 35.5° C versus 37° C in the non-deceased (p = 0.006). The percentage of newborns who underwent =2 tranfers was 57% in the deceased infants versus 30% in the non-deceased ones (p=0,02). In Yaoundé, transfers conditions of newborns in precarious conditions of life hinder early neonatal prognosis because of an erratic itinerary, which increases the risk of hypothermia and death. This reinforces the need for a perinatal network.

    A study of volcanic risk perception was carried out in rural communities around the Mount Cameroon volcano between August and December 2008. The results indicate that risk perception reflects the levels of threat to which a resident population has been exposed to previously. Results of 70 responses to questionnaires show that local knowledge of hazards is high. Most respondents correctly indicated that earthquake and lava flow activities would affect resident population most in the future. By contrast, respondent's ability to adapt and protect themselves from the effects of future eruptions is poor, and inhabitants would likely shift responsibility for their protection to the requisite experts. This study confirms that there is little knowledge of any existing emergency plan, little or no educational outreach activities, but a high perceived need for information about and implementation of such actions. Knowledge about natural threats is found to be directly related to past exposure to volcanic hazard, and is significantly higher for people living along the southern than those along the northern slopes of Mt. Cameroon. The data also show that the media remains the most accessible channel for hazard communication, and that the internet is a growing information source that should be used to reach out to the younger generation. It is clear from the results of this study that major education and information efforts are required to improve the public's knowledge, confidence in the government, and growing self-reliance, in order to improve both collective and individual capacity to face future volcanic emergencies.

    Background The Anopheles nili group of mosquitoes includes important vectors of human malaria in equatorial forest and humid savannah regions of sub-Saharan Africa. However, it remains largely understudied, and data on its populations’ bionomics and genetic structure are crucially lacking. Here, we used a combination of nuclear (i.e. microsatellite and ribosomal DNA) and mitochondrial DNA markers to explore and compare the level of genetic polymorphism and divergence among populations and species of the group in the savannah and forested areas of Cameroon, Central Africa. Principal Findings All the markers provided support for the current classification within the An. nili group. However, they revealed high genetic heterogeneity within An. nili s.s. in deep equatorial forest environment. Nuclear markers showed the species to be composed of five highly divergent genetic lineages that differed by 1.8 to 12.9% of their Internal Transcribed Spacer 2 (ITS2) sequences, implying approximate divergence time of 0.82 to 5.86 million years. However, mitochondrial data only detected three major subdivisions, suggesting different evolutionary histories of the markers. Conclusions/Significance This study enlightened additional cryptic genetic diversity within An. nili s.s. in the deep equatorial forest environment of South Cameroon, reflecting a complex demographic history for this major vector of malaria in this environment. These preliminary results should be complemented by further studies which will shed light on the distribution, epidemiological importance and evolutionary history of this species group in the African rainforest, providing opportunities for in-depth comparative studies of local adaptation and speciation in major African malaria vectors.

    The fourth Millennium Development Goals targets reduction by 2/3 the mortality rate of under-fives by 2015. This reduction starts with that of neonatal mortality representing 40% of childhood mortality. In Cameroon neonatal mortality was 31‰ in 2011. We assessed the trends, associated factors and causes of neonatal deaths at the Yaounde Gynaeco-Obstetric and Pediatric Hospital. The study was a retrospective chart review. Data was collected from the hospital records, and included both maternal and neonatal variables from 1st January 2004 to 31st December 2010. The neonatal mortality was 10%. Out-borns represented 49.3% of the deceased neonates with 11.3% born at home. The neonatal mortality rate followed a downward trend dropping from 12.4% in 2004 to 7.2% in 2010. The major causes of deaths were: neonatal sepsis (37.85%), prematurity (31.26%), birth asphyxia (16%), and congenital malformations (10.54%). Most (74.2%) of the deaths occurred within the first week with 35% occurring within 24hours of life. Mortality was higher in neonates with birth weight less than 2500g and a gestational age of less than 37 weeks. In the mothers, it was high in single parenthood , primiparous and in housewives and students. There has been a steady decline of neonatal mortality since 2004. Neonatal sepsis, prematurity, birth asphyxia and congenital malformations were the major causes of neonatal deaths. Neonatal sepsis remained constant although at lower rates over the study period.

    Abstract Recent field inventories and taxonomic research in Central Africa have resulted in the discovery of many new orchid species. Five specimens of an apparently new Angraecum species were collected in Gabon and Cameroon. They stand out for their hanging habit and short zig-zag stem. Morphology of leaves and habit is somewhat comparable to Angraecum cultriforme and Angraecum stolzii, two species from East Africa. Flowers of the novelty share the general morphology of Angraecum pyriforme from which the new species is distinguished by being smaller and with a different lip-spur ratio. Here we show that these five specimens represent a new species, described here as Angraecum lanceolatum. The distinguishing traits include thin lanceolate leaves, convolute distally, with a rhombic lip shape. Dichotomous key to four Central African species of sect. Conchoglossum and a table of the diagnostic characters of the seven related Continental African Angraecum taxa are included here. A preliminary assessment of the conservation status of Angraecum lanceolatum is provided, using the IUCN Red List Categories and Criteria. PMID:27081350

    The petrography, mineral chemistry and geochemical features of the Sabongari alkaline complex are presented and discussed in this paper with the aim of constraining its petrogenesis and comparing it with other alkaline complexes of the Cameroon Line. The complex is mainly made up of felsic rocks: (i) granites predominate and include pyroxene-amphibole (the most abundant), amphibole-biotite, biotite and pyroxene types; (ii) syenites are subordinate and comprise amphibole-pyroxene and amphibole-biotite quartz syenites; (iii) pyroxene-amphibole-biotite trachyte and (iv) relatively abundant rhyolite. The minor basic and intermediate terms associated with felsic rocks consist of basanites, microdiorite and monzodioites. Two groups of pyroxene bearing rocks are distinguished: a basanite-trachyte-granite (Group 1) bimodal series (SiO2 gap: 44 and 63 wt.%) and a basanite-microdiorite-monzodiorite-syenite-granite (Group 2) less pronounced bimodal series (reduced SiO2 gap: 56-67 wt.%). Both are metaluminous to peralkaline whereas felsic rocks bare of pyroxene (Group 3) are metaluminous to peraluminous. The Group 1 basanite is SiO2-undersaturated (modal analcite in the groundmass and 11.04 wt.% normative nepheline); its Ni (240 ppm) and Cr (450 ppm) contents, near mantle values, indicate its most primitive character. The Group 2 basanite is rather slightly SiO2-saturated (1.56 wt.% normative hypersthene), a marker of its high crustal contamination (low Nb/Y-high Rb/Y). The La/Yb and Gd/Yb values of both basanites (1: 19.47 and 2.92; 2: 9.09 and 2.23) suggest their common parental magma composition, and their crystallization through two episodes of partial melting (2% and 3% respectively) of a lherzolite mantle source with <4% residual garnet. The effects of crustal contamination were selectively felt in the values of HFSE/LREE, LREE/LILE and LREE/HFSE ratios, known as indicators. Similar features have been recently obtained in the felsic lavas of the Cameroon Volcanic Line.

    Intertidal mangrove ecosystems are sensitive to climate change impacts, particularly to associated relative sea level rise. Human stressors and low tidal range add to vulnerability, both characteristics of the Doula Estuary, Cameroon. To investigate vulnerability, spatial techniques were combined with ground surveys to map distributions of mangrove zones, and compare with historical spatial records to quantify change over the last few decades. Low technology techniques were used to establish the tidal range and relative elevation of the mapped mangrove area. Stratigraphic coring and palaeobiological reconstruction were used to show the longer term biological history of mangroves and net sedimentation rate, and oral history surveys of local communities were used to provide evidence of recent change and identify possible causes. Results showed that the seaward edge of mangroves had over two thirds of the shoreline experienced dieback at up to 3 m per year over the last three decades, and an offshore mangrove island had suffered 89% loss. Results also showed low net sedimentation rates under seaward edge mangroves, and restricted intertidal elevation habitats of all mangroves, and Avicennia and Laguncularia in particular. To reduce vulnerability, adaptation planning can be improved by reducing the non-climate stressors on the mangrove area, particularly those resulting from human impacts. Other priorities for adaptation planning in mangrove areas that are located in such low tidal range regions are to plan inland migration areas and strategic protected areas for mangroves, and to undertake management activities that enhance accretion within the mangroves.

    Tuberculosis remains a major public health problem in sub-Saharan Africa. District hospitals (DHs) play a central role in district-based health systems, and their relation with vertical programmes is very important. Studies on the impact of vertical programmes on DHs are rare. This study aims to fill this gap. Its purpose is to analyse the interaction between the National Tuberculosis Control Programme (NTCP) and DHs in Cameroon, especially its effects on the human resources, routine health information system (HIS) and technical capacity at the hospital level. We used a multiple case study methodology. From the Adamaoua Region, we selected two DHs, one public and one faith-based. We collected qualitative and quantitative data through document reviews, semi-structured interviews with district and regional staff, and observations in the two DHs. The NTCP trained and supervised staff, designed and provided tuberculosis data collection and reporting tools, and provided anti-tuberculosis drugs, reagents and microscopes to DHs. However, these interventions were limited to the hospital units designated as Tuberculosis Diagnostic and Treatment Centres and to staff dedicated to tuberculosis control activities. The NTCP installed a parallel HIS that bypassed the District Health Services. The DH that performs well in terms of general hospital care and that is well managed was successful in tuberculosis control. Based on the available resources, the two hospitals adapt the organisation of tuberculosis control to their settings. The management teams in charge of the District Health Services are not involved in tuberculosis control. In our study, we identified several opportunities to strengthen the local health system that have been missed by the NTCP and the health system managers. Well-managed DHs perform better in terms of tuberculosis control than DHs that are not well managed. The analysis of the effects of the NTCP on the human resources, HIS and technical capacity of DHs

    Introduction Neonatal outcomes can be directly and indirectly affected by caesarean delivery (CD). Data on CD rates in semi-urban and rural hospitals in resource-limited settings are scarce and yet are needed to better guide the care of women and neonates in these settings. we carried out this study to determine the frequency of CD, its indications and the frequency of the various adverse neonatal outcomes (ANO) in the Limbe Regional Hospital (LRH) and the Buea Regional Hospital (BRH), Cameroon. We also assessed the relationship between the indication for CD and ANO in the said hospitals. Methods This was a hospital-based retrospective and prospective cross-sectional study using descriptive and analytic methods conducted in the LRH and the BRH maternity units within a nine months period in 2015. Informed consent was obtainedfrom mothers of the neonates. Data analyses were performed using Epi-Info 3.5.4 software. Results We recruited 199 neonates born through CD. The prevalence of CD was 13.3% with cephalopelvic disproportion (CPD) being the most frequent (32.2%) indication for CD. There were 52 (26.1%) ANO following CD and respiratory distress was the most common 24 (46.2%) of all ANO. Emergency indications for CD were associated with more ANO 49 (34.5%) as compared to elective indications for CD 3 (5.3%) [p-value<0.001]. We noted a significant association between indications for CD and the various type of ANO, with CPD having the worse prognostic neonatal outcomes 30.8% [p-value=0.02]. Conclusion The prevalence of ANO associated with CD in our hospitals was high with a worrying prognosis. While the exact reasons are unknown, the creation of well-equipped neonatal units with trained staff, may contribute to reduce neonatal morbidity and fatalities. Furthermore, the association of CPD to worse prognostic neonatal outcomes calls for clinicians, to consider additional management options, such as antibiotic prophylaxis and oxygen therapy to the neonates, prior to CD

    The fourth Millennium Development Goals targets reduction of the mortality rate of under-fives by 2/3 by the year 2015. This reduction starts with that of neonatal mortality representing 40% of childhood mortality. In Cameroon neonatal mortality was 31% in 2011. We assessed the trends, associated factors and causes of neonatal deaths at the Yaounde Gynaeco-Obstetric and Pediatric Hospital. The study was a retrospective chart review. Data was collected from the hospital records, and included both maternal and neonatal variables from 1(st) January 2004 to 31(st) December 2010. The neonatal mortality was 10%. Out-borns represented 49.3% of the deceased neonates with 11.3% born at home. The neonatal mortality rate followed a downward trend dropping from 12.4% in 2004 to 7.2% in 2010. The major causes of deaths were: neonatal sepsis (37.85%), prematurity (31.26%), birth asphyxia (16%), and congenital malformations (10.54%). Most (74.2%) of the deaths occurred within the first week with 35% occurring within 24 hours of life. Mortality was higher in neonates with birth weight less than 2500 g and a gestational age of less than 37 weeks. In the mothers, it was high in single parenthood, primiparous and in housewives and students.. There has been a steady decline of neonatal mortality since 2004. Neonatal sepsis, prematurity, birth asphyxia and congenital malformations were the major causes of neonatal deaths. Neonatal sepsis remained constant although at lower rates over the study period.

    Mineralogical, chemical and geochronological studies constrained the origin of sapphires from Mayo Kila, Northwest Cameroon. The sapphires are mostly blue, with sizes ranging from 2 to 5 mm. The pale blue grains are transparent, whereas, other corundums are transparent to translucent and/or opaque. The sapphires are dominantly euhedral to sub-hedral with few polished lustrous grains, acquired features during moderate to short distance transport from a proximal source rock. Solid inclusions are limited to rutile and zircon. Trace element analysis of sapphires shows significant concentration (in ppm) in some elements: Fe (2208-14,473), Ti (82-1783), Ga (77-512), Mg (0.9-264.9), Cr (b.d.l -168) and V (1.3-82). The other elements (e.g. Sn, Nb, Ta, Th, Zr, Ni, Ce) are generally below 10 ppm. The calculated ratios for some of the selected elements show an extreme variation: Fe/Mg (43-3043), Fe/Ti (2-76), Ti/Mg (1-328), and Ga/Mg (0.4-363). They are dominantly corundum crystallized in alkaline magma (s) with few from metamorphic source (s). Trace elemental features with Hf (13,354-26,238 ppm), Th (4018-45,584 ppm) and U (7825-17,175 ppm), and Th/U (0.39-2.65) found in zircon inclusions are compatible with quantified values in magmatic crystallized zircons. The Cenozoic age (mean of 30.78 ± 0.28 Ma) obtained for zircon inclusions is close to the age of some igneous rocks found within the Cameroon Volcanic Line (e.g. rocks of the Mount Oku: 31-22 Ma), showing the same period of formation. The most probable source of the zircon host sapphires is the Oku Mountain located SW of Mayo Kila.

    71 maternal deaths at the Hospital Central Militar (Central Military Hospital) over the 12-year period 1968-1979 were reviewed. Maternal mortality rate was 23.07% which is higher than for the rest of the population. The most frequent type of mortality was due to obstetrical causes (69.01%) and here it was infection, pre-eclampsia, eclampsia, and hemorrhage which were most frequent. Among nonobstetrical causes, viral hepatitis was the most frequent. Death occurred more often among young women ages 21-25 with 2-4 previous deliveries. Death was considered evitable and probably evitable in 50 cases (70.42%). Of these, 62% were the responsibility of physicians and hospitals, while the rest were attributable to the patient and the community. (author's modified)

    Road traffic injury surveillance systems are a cornerstone of organized efforts at injury control. Although high-income countries rely on established trauma registries and police databases, in low- and middle-income countries, the data source that provides the best collection of road traffic injury events in specific low- and middle-income country contexts without mature surveillance systems is unclear. The objective of this study was to compare the information available on road traffic injuries in 3 data sources used for surveillance in the sub-Saharan African country of Cameroon, providing potential insight on data sources for road traffic injury surveillance in low- and middle-income countries. We assessed the number of events captured and the information available in Yaoundé, Cameroon, from 3 separate sources of data on road traffic injuries: trauma registry, police records, and newspapers. Data were collected from a single-hospital trauma registry, police records, and the 6 most widely circulated newspapers in Yaoundé during a 6-month period in 2009. The number of road traffic injury events, mortality, and other variables included commonly in injury surveillance systems were recorded. We compared these sources using descriptive analysis. Hospital, police, and newspaper sources recorded 1,686, 273, and 480 road traffic injuries, respectively. The trauma registry provided the most complete data for the majority of variables explored; however, the newspaper data source captured 2, mass casualty, train crash events unrecorded in the other sources. Police data provided the most complete information on first responders to the scene, missing in only 7%. Investing in the hospital-based trauma registry may yield the best surveillance for road traffic injuries in some low- and middle-income countries, such as Yaoundé, Cameroon; however, police and newspaper reports may serve as alternative data sources when specific information is needed.

    Purpose The aim of this study was to determine the prevalence and causes of bilateral and unilateral blindness in the town of Douala and its environs based on data from the ophthalmic unit of a tertiary hospital in Douala. Methods We conducted a retrospective epidemiological survey of consultations at the eye unit of the Douala General Hospital over the last 20 years (from January 1, 1990 to December 31, 2009). Results Out of the 1927 cases of blindness, 1000 were unilateral, corresponding to a hospital prevalence of 1.84% and 927 cases were bilateral, corresponding to a hospital prevalence of 1.71%. No statistically significant difference was noted between the two (P = 0.14). The leading causes of bilateral blindness were cataract (50.1%), glaucoma (19.7%), and diabetic retinopathy (7.8%) while the leading causes of unilateral blindness were cataract (40.4%), glaucoma (14.1%), and retinal detachment (9.1%). Cataract (51.2%), cortical blindness (16.3%), and congenital glaucoma (10%) were the leading causes of bilateral blindness in children aged less than 10 years. Conclusion Blindness remains a public health problem in the Douala region with a hospital prevalence which is relatively higher than the national estimate given by the National Blindness Control Program.

    Ruptured ectopic pregnancies are life-threatening emergencies, especially in developing countries, where many patients do not consult until rupture, sometimes with the patient already in hemorrhagic shock. In this situation, immediate blood transfusion is essential. Homologous blood products are not always available. Furthermore, homologous transfusion carries the risk of transmitting viruses such as HIV and hepatitis B and C. Autologous transfusion (intraoperative blood salvage) may thus be helpful. The authors present 6 cases of autologous transfusion performed at the Yaounde University Hospital (Cameroon) and recommend this method in developing countries where good quality blood cannot always be obtained rapidly.

    Risk factors for HIV transmission within a hospital setting were assessed using pre-structured questionnaires and observations. Of 409 respondents, 66.3% corresponded to the nursing staff, 14.4% doctors and 8.3% laboratory staff. The irregular use of gloves and other protective clothing for risky tasks, and recapping of needles after use were some of the risk factors identified, especially amongst nurses. Preventive measures were not always implemented by health personnel. More emphasis should be placed not only on diffusing universal precautions and recommendations for hospital staff safety, but accompanying measures for monitoring and evaluation of implementation of these standards are also indispensable.

    The comparison between contemporary and long-term weathering has been carried out in the Small Experimental Watershed (SEW) of Nsimi, South Cameroon in order to quantify the export fluxes of major and trace elements and the residence time of the lateritic weathering cover. We focus on the hillside system composed of a thick lateritic weathering cover topped by a soil layer. This study is built on the recent improvements of the hillside hydrological functioning and on the analyses of major and trace elements. The mass balance calculation at the weathering horizon scale performed with the parent rock as reference indicates (i) strong depletion profiles for alkalis (Na, K, Rb) and alkaline earths (Mg, Ca, Sr, Ba), (ii) moderate depletion profiles for Si, P, Cd, Cu, Zn, Ni and Co, (iii) depletion/enrichment profiles for Al, Ga, Ge, Sn, Pb, LREE, HREE, Y, U, Fe, V, Cr, Mn. It is noteworthy that (i) Mn and Ce are not significantly redistributed according to oxidative processes as it is the case for Fe, V and Cr, and (ii) Ge is fractionated compared to silica with enrichment in Fe-rich horizons. The calculations performed for the topsoil with iron crust as parent material reference reveal that the degradation of the iron crust is accompanied by the loss of most of the constituting elements, among which are those specifically accumulated as the redox sensitive elements (Fe, V, Cr) and iron oxide related elements like Th. The overall current elemental fluxes from the hillside system at the springs and the seepage zones are extremely low due to the inert lateritic mineralogy. Ninety-four percent of the whole Na flux generated from the hillside corrected from atmospheric deposits (77 mol/ha/yr) represents the current weathering rates of plagioclase (oligoclase) in the system, the other remaining 6% may be attributed to the dissolution of hornblende. The silica hillside flux is 300 mol/ha/yr and can be mostly attributed to the plagioclase and kaolinite dissolution. Al and Ga

    Women older than 40 years have been termed "advanced maternal age" and considered to be at risk of adverse pregnancy outcome. This study aimed to examine the obstetrical outcomes among primiparous and multiparous African advanced maternal age women. We conducted a retrospective cohort study study at two teaching hospitals at Yaounde, Cameroon. From the hospital records, obstetrical characteristics of 585 consecutive women aged 40 or above who delivered from January 2007 to December 2011 were compared with those of 1816 younger mothers aged 20 to 29 years as control cases. Associations between maternal age and selected obstetrical variables were assessed with the contigency X (2) test or two-tailed Fisher exact test. Primiparous and multiparous advanced maternal age were more likely to undergo cesarean delivery than were their younger counterparts (38.5% vs 13.5%, RR=2.85, p<0.05 and 16.1% vs 9.1%, RR=1.76, p<0.05). Older primiparous women had similar perinatal outcomes than their younger counterparts. Older multiparous women had increased incidence of preeclampsia/eclampsia (2.4% vs 0.6%, RR=4, p<0.01); antepartum hemorrhage (1.8% vs 0.8%, RR=2.25, p<0.01); fetal distress (3.5% vs 1.3%, RR=2.69, p<0.01); fetal death (3.5% vs 1.6%, RR= 2.18, p<0.05); postpartum hemorrhage (2.4% vs 1.2%; RR=2, p<0.05); preterm delivery (12% vs 9.2%, RR=1.30, p<0.05); low birth weight (11% vs 7.7%, RR=1.42, p<0.05); admission to special care neonatalogy unit(14.1% vs 10.2%, RR=1.38, p<0.05); low Apgar scores at 1min and 5min; and perinatal mortality (3.5% vs 1.6, RR=2.18, p<0.05). Advanced maternal age women are at higher risk to cesarean delivery. Increased risk of antepartum and intra partum complications among multiparous advanced maternal age women were associated to adverse perinatal outcome. Our results are in concordance with the view that increased risk of adverse perinatal outcome with advanced maternal age is indirectly related to age through the increased risk of

    To reduce development costs at the Mokoko-Abana field, all production equipment was installed in deck units during fabrication and the equipment was precommissioned in the contractors' yards before loadout. The 5,000-ton (4500-Mg) central production facilities deck, however, exceeded lifting capabilities of available marine equipment, so a unique installation technique was developed that uses tidal changes and rapid barge ballasting to lower the completed deck onto a specially designed jacket.

    The World Health Organization has estimated that the global incidence of neonatal deaths was 2,8 million in 2015, of which 47,6% were due to infections. These infections can affect newborns babies ages 0-1 month through 3 months. This is a prospective study conducted from 1 March to 30 June 2015 in the Neonatology service of the Laquintinie Hospital at Douala. All symptomatic newborns with or without anamnestic criteria and all asymptomatic newborns, with at least an infectious risk and a positive blood culture or an abnormal blood count or positive C-reactive protein were included in the study. Of the 310 newborns enrolled in the study, 300 were retained for neonatal infection, corresponding to a total incidence of 96.8%. We performed 104 cultures, of which 25 were positive, corresponding to an incidence of confirmed neonatal infection of 24%. The factors associated with infection were unexplained preterm birth < 35 weeks of amenorrhea (45,1%) and neonatal resuscitation (34,8%). Fever (56%) and neurological disorders (48.8%) were the most frequent clinical symptoms. Gram-negative bacteria were the most frequent germs (56%). Imipenem (95%) and amikacin (66.7%) were the most effective antibiotics. Outcome was favorable in 66,4% of cases and the overall mortality rate was 33,6%. This study revealed a high prevalence of neonatal bacterial infection in this Hospital. Bacterial ecology was dominated by Gram-negative bacteria. It was recorded a significant resistance to the most widely used antibiotics and a fairly high mortality.

    Detailed analyses and interpretation realized by combining existing 2D reflection seismic and Gravity/Magnetic data of the Logone Birni Basin (LBB) in the West and Central African Rift System (WCAS) have revealed the distribution of the main buried volcanic bodies as well as their relationships with the structural and tectonic evolution of this basin. The volcanic activity in the LBB is restricted to the Cretaceous period. Three main volcanic episodes are identified and are associated to the Neocomian, Late Albian and Cenomanian-Turonian rifting phases respectively. The volcanic bodies within the Lower Cretaceous are either lying directly on basement or are mainly interbedded with the contemporaneous sediments whereas the Upper Cretaceous bodies are morphologically expressed in the forms of dykes and sills. The volcanic activity was more intense in the western region of the central LBB (Zina sub-basin) along the Cameroon-Nigeria border whereas it was scanty and scattered in the other parts of the basin. The main volcanic dykes are found on the flanks of the major faults bounding basement horsts or in crestal positions in association with syndepositional faults. Although WCAS is associated with large amount of crustal extension and minor volcanism, the intense volcanic activity observed in LBB during the Cretaceous suggests that the intrusive zone during this period was confined to the basement beneath the study area flanked respectively to the north, south and southwest by the Lake Chad, Poli and Chum triple junctions. Tensional stresses generated by this localized domal uplift accounts for most of the observed tectonic structures where major faults transected the entire lithosphere, thus providing conduits for magma migration.

  18. Impact of repeated ivermectin treatments against onchocerciasis on the transmission of loiasis: an entomologic evaluation in central Cameroon

    PubMed Central

    2013-01-01

    Background Annual community-directed treatment with ivermectin (CDTI) have been carried out since 1999 in the Lekie division (central region of Cameroon where most cases of Loa-related post ivermectin severe adverse events were reported) as part of the joined activities of the African Programme for Onchocerciasis Control (APOC) and Mectizan® Donation Program (MDP). As large-scale administration of ivermetine was demonstrated to be an efficient means to control loiasis transmission, it was hypothesized that CDTI would have lowered or halted the transmission of Loa loa in the Lekie division after 13 years of annual drug administration, indicating a possible reduction in the occurrence of Loa-related post-ivermectin severe adverse events. Methods A 4-month entomologic study was carried out from March to June 2012 in the Lekie division to evaluate the impact of 13 years of CDTI on the transmission of L. loa whose baseline data were recorded in 1999–2000. Results There was a significant reduction in the infection rate for Chrysops silacea and C. dimidiata from 6.8 and 9% in 1999–2000 to 3 and 3.6% in 2012, respectively. The differences in the infective rate (IR) (percentage of flies harboring head L3 larvae), potential infective rate (PIR) (percentage of flies bearing L3 larvae), mean head L3 larvae load (MHL3) (average L3 per infective fly) and mean fly L3 larvae load (MFL3) (average L3 per potentially infective fly) for both C. silacea and C. dimidiata were not significantly different between the two investigation periods. The biting density (BD) was almost three-fold higher in 2012 for C. silacea but not for C. dimidiata. The transmission potential (TP) which is a function of the BD, was higher in the present study than in the baseline investigation for each species. Conclusion The infection rate remaining high, the high TP and the stability observed in the IR, PIR, MHL3 and MFL3 after 13 years of CDTI suggest that transmission of L. loa is still active. This is

    The insertion and the permanence of central venous catheters (CVC) represent potential sources of infection contracted in hospital. The evaluation of the risk of CVC-associated infections was evaluated in a retrospective study during the period 2007-2010 in a Hospital of Central Italy. A total of 514 CVC were collected and examined by microbiological techniques and, among the examined patients, 450 CVC blood cultures were collected. Cultures were performed collecting a portion of 5-6 cm of intravenous catheters in liquid medium and spread on selective media for Gram-positive and Gram-negative bacteria and yeasts; blood specimens were obtained through peripheral venous punctures and analyzed by a commercial automated system. 308/514 (59.90%) samples were positive to the microbiological culture. Staphylococcus aureus, S. epidermidis and other coagulase negative Staphylococci (CNS) were the prevalent Gram-positive bacteria. Among Gram-negative bacteria, Enterobacteriaceae and Pseudomonaceae were the main bacteria isolated. A higher prevalence of Gram-positive bacteria was observed in Neonatal Pathology (90.90%). The Intensive Care Unit (ICU) showed 73.10% of positive cultures with 54.12% of Gram-positive isolates. Among positive blood cultures (38%), Gram-positive bacteria were the main bacteria isolated. The high prevalence of catheter-related infections requires accurate surveillance and the assumption of preventive measures in particular during catheter insertion.

    Obesity is a rising public health issue worldwide. Guidelines regarding maternal body mass index (BMI) and gestational weight gain (GWG) are missing in Cameroon where maternal mortality rate remains very high. We hypothesized that obesity and inappropriate GWG are associated with poor pregnancy outcomes. We aimed at assessing associations of BMI and GWG with pregnancy outcomes. This was a retrospective cohort study at the Yaoundé Central Hospital. We included women with term singleton deliveries in the post-partum ward. The World Health Organisation classification of BMI and the United States Institute Of Medicine (IOM) categories of GWG were used to stratify participants. Poor maternal outcome was defined by the occurence of caesarean section, preeclampsia or obstetrical haemorrhage. Poor perinatal outcome was defined by the occurence of perinatal death, admission in intensive care unit, low birth weight, macrosomia or fifth minute Apgar score <7. Multiple logistic regressions were used to calculate unadjusted and adjusted Odds Ratios (uOR, aOR) for poor maternal outcome (PMO) and for poor perinatal outcome (PPO) in each category of BMI and GWG. Adjustment was done for age, scarred uterus, sickle cell disease, malaria, human immunodeficiency virus (HIV) infection, parity and smoking. Of the 462 participants, 17 (4 %) were underweight (BMI < 18.5), 228 (49 %) had normal pre-pregnancy BMI, 152 (33 %) were overweight (25 ≤ BMI < 30) and 65 (14 %) were obese (BMI ≥ 30). Following the IOM recommendations, GWG was normal for 186 (40 %) participants, less than recommended for 131 (28 %) and above the recommended norms for 145 (32 %). GWG above the IOM recommendation was significantly associated with PMO (aOR: 1.7, 95 % CI 1.1-2.8). GWG less than the IOM recommended values, overweight and obesity were not significantly associated with poor pregnancy outcomes. While waiting for local recommendations for GWG, the IOM recommendations can be used for

    Scientifically-based integration of therapeutic and prophylactic institutions is needed for better meeting the population requirement of medical care, and it is desirable to unite the financial resources and personnel; such is the objective reality for municipal therapeutic and prophylactic institutions of local public health systems. In order to make medical care available for the population and to ensure its high quality, structural changes in the public health of a region are needed. These changes include integration of medical services of these territories; creation of a network of therapeutic and prophylactic institutions corresponding to medical demographic structure of population, so that the scope of medical care be increased and specialized care made easier available for the population; and creation of the optimal managing system. Comparative studies of population health and its time course, public health organization at neighboring territories, where therapeutic and prophylactic institutions, such as Central Municipal Hospital and Central Regional Hospital have autonomous managing and financing, confirmed the need in integration of public health units functioning at a certain territory into a universal system, and in development of approaches to overcome the present-day miscellaneous network by integrating the activities of treatment-and-prophylaxis institutions. Identical economic, geographic, and macroeconomic living conditions of the population, similarity of medical demographic structure and similar changes in it, as well as similar morbidity structure, are sufficient grounds for integration of public health services.

    The main geological feature of Central Cameroon is the wide spread occurrence of granitoids emplaced in close association with transcurrent regional shear zones. The basement of this vast domain is a Paleoproterozoic ortho-and para-derivative formation, which has been intensely reworked, together with subsequent intrusions and sediments, during the Panafrican orogenesis in the Neoproterozoic. As consequence, the area underwent pervasive metamorphism and intense deformation. This makes it difficult to distinguish between Panafrican metasediments or syntectonic plutonites and their respective basement. Our study presents zircon features (CL-BSE-SE) and in-situ U-Th-Pb LA-MC-ICP-MS geochronology of a meta-sedimentary pyroxene-amphibole-bearing gneiss of the Méiganga area in Central Cameroon. Based on the Internal structures of the zircon four characteristic zonation patterns can be deciphered: 1) cores with magmatic oscillatory zonation 2) zircons with oscillatory or sector zonation, 3) zircons with sector zoning or blurred zoning, and 4) narrow bright un-zoned rims. These groups suggest that the rock experienced a number of geological events. Considering this zircon characteristic, the U-Th-Pb data allow to distinguish four ages: 2116 ± 57 Ma, consistent with ages from the Paleoproterozoic West Central African Belt; 2551 ± 33 Ma which marks a late Neoarchean magmatic event; 2721 ± 27 Ma related to a Neoarchean magmatic even in Central Cameroon, similar to one found in the Congo Craton. A zircon core gives ages around 2925 Ma which provides some evidence of the presence of the Mesoarchean basement prior to the Neoarchean magmatism. A weighted average of lower intercepts ages gives a value of 821 ± 50 Ma, representing the age of later metamorphism event. The various characteristic group and related ages reflect not only the complexity of the history of the pyroxene amphibole gneiss, but also show that the meta-sediment has at least three zircon contributing

    2010-01-01

    Background While influenza surveillance has increased in most developing countries in the last few years, little influenza surveillance has been carried out in sub-Saharan Africa and no information is available in Central Africa. The objective of this study was to assess the prevalence of influenza viruses circulating in Yaounde, Cameroon and determine their antigenic and genetic characteristics. Methods Throat and/or nasal swabs were collected from November 2007 to October 2008 from outpatients with influenza-like illness (ILI) in Yaounde, Cameroon and analyzed by two different techniques: a one-step real time reverse transcription-polymerase chain reaction (RT-PCR) and virus isolation in MDCK cells. Typing and subtyping of virus isolates was performed by hemagglutination inhibition (HI), and viruses were sent to the WHO Collaborating Centre in London, UK for further characterization and analyses of antiviral resistance by enzyme inhibition assay and nucleotide sequencing. Results A total of 238 patients with ILI were sampled. During this period 70 (29%) samples were positive for influenza by RT-PCR, of which only 26 (11%) were positive by virus isolation. By HI assay, 20 of the 26 isolates were influenza type A (10 H3N2 and 10 H1N1) and 6 were influenza type B (2 B/Victoria/2/87 lineage and 4 B/Yagamata/16/88 lineage). Seven (70%) of the H1N1 isolates were shown to be resistant to oseltamivir due to a H275Y mutation. Conclusions This study confirmed the circulation of influenza A(H1N1), A(H3N2) and B viruses in the human population in Central Africa and describes the emergence of oseltamivir-resistant A(H1N1) viruses in Central Africa.

  7. Effects of the soil-forming factors climate and time on soils of Mount Cameroon (Central Africa)

    Knowledge on rates of soil-forming processes in humid-tropical climate is limited, mainly because objects that are suitable for studying soil chronosequences are rare in tropical regions. Mt. Cameroon, located at the Gulf of Guinea in SW Cameroon, between latitudes 4°00' to 4°20'N, is an ideal object for this purpose. Its volcanic activity started 11 Ma ago and still continues today, providing lava flows of different ages and rather uniform basaltic composition. The climate of the area is humid-tropical, characterised by a distinct gradient in mean annual precipitation (MAP). MAP amounts to > 9000 mm on the SW flank, near the coast, decreasing to < 2000 mm on the opposite flank, in the rain shadow of Mt. Cameroon's peak. Eight soil profiles, including six on historical lava flows of different ages and two on older (Holocene) lava flows characterised by contrasting MAP, were described and analysed. Soil formation proceeds from Nudilithic Leptosol (on a 13 year-old lava flow) to Skeletic Mollic Leptic Vitric Silandic Andosol (54 years), Umbric Leptic Silandic Andosol (91 and 104 years), and finally to Umbric Silandic Andosol (Holocene, MAP 2400 mm) or Umbric Amphisilandic Endoaluandic Andosol (Holocene, MAP 8000 mm). The general trends of Fed/Fet and (Ca+Mg+K+Na)/Al molar ratios over time indicate progressive weathering, formation of pedogenic iron oxides, and leaching of Ca, Mg, K and Na. Irregular uppermost parts of the depth curves of these ratios in some soils suggest addition of fresh ash or dust. Organic matter (OM) contents are remarkably high in the 104 year-old soils that are located at 3000 m a.s.l., compared to all other analysed soils. A possible explanation is that biomass production and thus OM input are still high at this elevation, whereas the altitudinal temperature decline leads to decreased OM decomposition compared to the lower slope.

    Background Transfusion-transmissible infections (TTIs) pose a major health risk in Cameroon given the high prevalence of such pathogens and increased demands for blood donations in the local communities. This study aims at establishing the prevalence of commonly encountered TTIs among blood donors and transfusion-related complications among recipients in an urban center of Cameroon. Methods A total of 477 blood donors and 83 blood recipients were recruited by consecutive sampling at the Laquintinie Hospital in Douala (LHD), Cameroon. Serum samples from blood donors were tested by quantitative enzyme-linked immunosorbent assays (ELISA) and/or using various Rapid diagnostic test (RDT) for presence of Hepatits B (HBV) viral antigens, and antibodies to human immunodeficiency (HIV-1/2), Hepatits B (HCV) and Treponema pallidum. Recipient’s medical records were also analyzed for possible transfusion-associated complications. Results The male/female sex ratio of the blood donors was 4/1 with a mean age of 30.2 (Sd = 8.3) years. Of all blood donors, 64/467 (13.7%) were infected by at least one of the four TTIs. Infected volunteer donors represented 8.3% while infected family donors comprised 14.3% of the donor population. The prevalence of HCV, HIV, HBV and T. pallidum were 1.3%, 1.8%, 3.5%, and 8.1%, respectively. More than half of the blood recipients were female (78.3%) and the mean age was 20.6 (SD = 16.1) years. The causes of severe anemia indicative of transfusion in recipients varied with wards (postpartum hemorrhage, caesarean section, uterine or cervical lacerations, abortions, urinary tract infections, severe malaria, vaso-occlusive attacks, wounds and gastrointestinal bleeding). The most frequent complications were chills and hematuria, which represented 46.1% of all observed complications. Other complications such as nausea, vomiting, jaundice, sudden diarrhea, anxiety, tachycardia, or hyperthermia were also found in recipients. Three cases of deaths

    Background: Liver disease related to Hepatitis B (HBV) and C (HCV) infection has become a major cause of morbidity and mortality in HIV/AIDS patients. Data on the prevalence of HBV and HCV in Cameroon remains inconclusive. Objective: We aimed to determine the sero-prevalence and correlates of Hepatitis markers in HIV/AIDS patients in two Regional Hospitals. Methods: A cross-sectional study carried out from December 2014 to March 2015. HIV/AIDS patients aged 21 were included and above, receiving care at HIV treatment centres. Data was collected using a structured questionnaire. Blood samples were collected to screen for Hepatitis with HBsAg and anti HCV antibody rapid immunochromatographic test kits. Correlates of hepatitis were investigated by logistic regression. STATA was used for data analysis. Results: We included 833 HIV/AIDS patients,78.8% (657) were female. Mean age was 44(SD 11) years. Prevalence of Hepatitis in general (total of two viral markers tested) was 8.9% (74/833), with 6.1% for HBsAg and 2.8% for Anti-HCV antibodies. From multivariate analysis, the likelihood of having hepatitis was independently increased by a history of surgical interventions [OR: 1.82(1.06-3.14)], and of sexually transmitted infections [OR: 2.20(1.04-4.67)]. Conclusion: Almost one in ten participants with HIV/AIDS attending the BRH and LRH tested positive for either HBsAg or anti HCV antibodies. Screening for HBV and HCV should therefore be integrated to the existing guidelines in Cameroon as it can influence management. More studies are needed to evaluate the extent of liver disease and magnitude of HIV suppression in hepatitis and HIV coinfection in this setting. PMID:27867437

    Sore throat is a common complaint in general practice which is more frequent in children. The most frequent pathogenic bacteria associated with this infection is Streptococcus pyogenes. Rapid Antigen Diagnostic Test (RADT) facilitates the rapid identification and consequently prompt treatment of patients, prevents complications, and also reduces the risk of spread of Group A Streptococcus (GAS). The main objective of this study was to assess the diagnostic value of a rapid streptococcal antigen detection test in patients with sore throat. A cross-sectional descriptive study was carried out from January to April 2011 on patients aged 3 to 72 years consulting for pharyngitis or sore throat at the paediatric and Ear, Nose and Throat units of the University Teaching Hospital Yaounde and the Central Hospital Yaounde. Two throat swabs were collected per patient. One was used for the rapid test and the other for standard bacteriological analysis. The prevalence of GAS in the study population was 22.5%. Out of the 71 samples collected, the RADT detected group A streptococcal antigens in 12 of 16 positive cultures giving a sensitivity of 75%. The specificity of the rapid test was 96%, with positive predictive value of 85.7%, and negative predictive value of 93% respectively. Rapid test may have an additional value in the management of patients with high risk of having GAS infection. However, tests with a higher sensitivity are needed for accurate and reliable results for early diagnosis of patients with sore throat caused by GAS.

    In West and West Central Africa, multiple subtypes, circulating recombinant forms (CRF), and high proportions of unique recombinant forms (URF) are documented. The predominance of recombinants strongly suggests that dual infections occur frequently. In the present study, we adapted the multi-region hybridization assay (MHA), previously developed to identify dual infections in geographic regions where few HIV-1 variants circulate, to identify HIV-1 variants and dual infections. We designed clade-specific probes in three genomic regions (gag p17, vpu, nef) to detect eight different variants that are common in this part of Africa (A, B/D, C, F, G, CRF02_AG, CRF06_cpx, CRF22_01A1). The assay was validated with 163 samples representing the corresponding HIV-1 variants. Depending on the genomic regions, the global sensitivity of the assay ranged from 86% to 94%, and the global specificity was between 85% and 96%. The assay was then applied on 156 antiretroviral treatment-naive patients from Cameroon. The MHA assay identified 79%, 85% and 90% of the strains in nef, gag and vpu regions, respectively. The subtype/CRF distribution and the proportion of inter-region recombinants obtained by the new MHA assay were in accordance with known subtype/CRF distribution in Cameroon. Moreover, the MHA assay identified 35 (22.4%) patients as dually infected, from which 20 were reactive in more than one region and/or with concordant multigenomic recombination pattern. Despite the high genetic diversity, we successfully developed an hybridization assay allowing identification of eight common HIV-1 variants circulating in West and West Central Africa. We documented high rates of dual infection in a low-risk population group, illustrating that the global evolution of HIV diversity is driven by dual infections. This assay could become a useful screening tool for the global surveillance and monitoring of inter-subtype/CRF dual infections in West and West Central Africa. Copyright © 2012

    HIV/AIDS is a major public health problem in Cameroon which had a prevalence of 5.1% in 2010 with 141 new infections per day. The fear of voluntary counseling and testing (VCT) is an obstacle to HIV prevention. To determine the prevalence of HIV-1, HIV-2 and HIV-1/HIV-2 co-infection among people attending a health facility for VCT. Venous blood was collected from participants using aseptic techniques in a descriptive observational cross-sectional study. DETERMINE HIV-1/2 and SD BIOLINE HIV-1/2 3.0 qualitative tests were used for the detection of HIV-1 and HIV-2 in their sera. Range and consistency checks were carried out on the data and analysed using Epi-Info. Of 290 individuals tested, 78(26.9%) were positive for HIV-1 and HIV-2. Among the 78 HIV positive individuals, 62 (79.5%) had HIV-1, 1(1.3%) had HIV-2 and 15(19.2%) had concurrent HIV-1/ HIV-2. Among those infected, 57(73.1%) were females including 21(26.9%) males. HIV-1 is the major cause of AIDS and VCT is well accepted. Co-infection with HIV-1/HIV-2 may lead to anti-retroviral drug resistance. VCT should be encouraged so that positive cases can initiate therapy on time to stay ahead of anti-retroviral drug resistance.

    Central Africa owns important renewable energy potential, namely hydro, solar and biomass. This important potential is still suffering from poor development up to the point where the sub region is still abundantly using the fossil energy and biomass as main power source. This is harmful to the climate and the situation is still ongoing. The main cause of the poor use of renewable energy is the poor management of resources by governments who have not taken the necessary measures to boost the renewable energy sector. Since the region is experiencing power shortage, thermal plants are among other solutions planned or under construction. Firewood is heavily used in remote areas without a sustainability program behind. This solution is not environment friendly and hence is not a long term solution. Given the fact that the region has the highest hydro potential of the continent, up to one-quarter of the world's tropical forest, important oil production with poor purchase power, the aim of this paper is to identify actions for improved access to sustainable, friendly, affordable energy services to users as well as a significant improvement of energy infrastructure in Central Africa and the promotion of small hydro and other renewable energy. The work will show at first the potential for the three primary energy sources which are solar, biomass and hydro while showing where available the level of development, with an emphasis on small hydro. Then identified obstacles for the promotion of clean energy will be targeted. From lessons learned, suggestions will be made to help the countries develop an approach aiming at developing good clean energy policy to increase the status of renewable energy and better contribute to fight against climate change. Cameroon has a great renewable energy potential and some data are available on energy. From the overview of institutional structure reform of the Cameroon power sector and assessments, specific suggestions based on the weaknesses

    Some chimpanzee populations exhibit ground night nesting, which occurs in different habitat types, is driven by a variety of interconnected factors, and may reflect cultural or social differences. This has important implications for ape conservation management, given that accurate nest builder identification is required to estimate density, crucial in monitoring, and allows inferences about environmental and social factors that may have contributed to the transition from tree to ground sleeping in early hominins. We conducted a 24-month marked nest count survey in La Belgique, Cameroon, and recorded the occurrence of chimpanzee tree and ground night nests, temperature and rainfall, predator and large mammal abundance, human activities, nesting tree species, and Uapaca spp. consumption. Ground night nesting occurred at a rate of 3.47% (n = 1,008), with more in swamps, in the dry season and with increasing human activities. We found no influence of leopard/elephant presence, but a possible influence of lack of nesting trees. We suggest chimpanzees visit swamps in the dry season (low water levels) for relief from hunting pressure and to consume Uapaca spp. fruits. Ground nesting may be enabled due to high abundance of terrestrial herbaceous vegetation, and may be favoured for inconspicuousness and safety from gun hunters.

  17. Estimating C3 vs. C4 vegetation cover from sedimentary records - a surface sediment test from Cameroon, Western Central Africa

    Carbon isotope fractionation associated with higher plant photosynthesis differs between the Calvin-Benson (C3) and Hatch-Slack (C4) cycles. It is possible to identify both C3 and C4 plants by measuring their δ13C values: C3 plants are depleted in δ13C compared with C4 plants. Higher plant lipid biomarkers, such as long-chain n-alkanes, which inherit the δ13C values representative of the carbon fixation pathway, are often used to reconstruct past vegetation cover (C3 vs. C4) for the African continent quantitatively. The percentage of C3 and C4 vegetation contribution to sedimentary n-alkanes can be determined by applying simple mixing models that assume two end-member δ13C values for both vegetation types. Here, we present a new dataset of δ13C values of n-alkanes from modern C3 and C4 plants and lake surface sediments with the aim to test the accuracy of these binary mixing models to infer C3 and C4 vegetation compositions from sedimentary records. Samples were collected in Cameroon across a natural gradient, which accommodates a wide range of climates and vegetation classes. Our results indicate that while the mean δ13C values of C4 plants remains relatively stable along the studied gradient (n-C29 alkane = -20±2‰), the mean δ13C values of C3 plants show larger variations (n-C29 alkane = -37±4‰). The latter observation can be attributed to environmental variables such as the relative humidity: n-C29 alkanes from C3 plants growing under high relative humidity (80%) had mean δ13C values of -40‰ while at low relative humidity (45%) they reached up to -31‰. These results suggest that δ13C values of C3 plants are not independent of environmental conditions, which likely reflects known physiological responses of leaves such as the decrease in stomatal conductance and increase in water use efficiency under drier conditions. The large variability of δ13C values of C3 plants across this transect further suggests that assigning an end-member value for C

    Knowledge of population structure in a major vector species is fundamental to an understanding of malaria epidemiology and becomes crucial in the context of genetic control strategies that are being developed. Despite its epidemiological importance, the major African malaria vector Anopheles funestus has received far less attention than members of the Anopheles gambiae complex. Previous chromosomal data have shown a high degree of structuring within populations from West Africa and have led to the characterization of two chromosomal forms, "Kiribina" and "Folonzo." In Central Africa, few data were available. We thus undertook assessment of genetic structure of An. funestus populations from Cameroon using chromosomal inversions and microsatellite markers. Microsatellite markers revealed no particular departure from panmixia within each local population and a genetic structure consistent with isolation by distance. However, cytogenetic studies demonstrated high levels of chromosomal heterogeneity, both within and between populations. Distribution of chromosomal inversions was not random and a cline of frequency was observed, according to ecotypic conditions. Strong deficiency of heterokaryotypes was found in certain localities in the transition area, indicating a subdivision of An. funestus in chromosomal forms. An. funestus microsatellite genetic markers located within the breakpoints of inversions are not differentiated in populations, whereas in An. gambiae inversions can affect gene flow at marker loci. These results are relevant to strategies for control of malaria by introduction of transgenes into populations of vectors.

    Adolescents are generally ill-equipped to deal with the burden of a pregnancy. A high prevalence of adolescent pregnancies is among the indicators of limitations toward the achievement of the Millennium Development Goals in most developing countries. We sought to determine the prevalence, 6-year trend, and adverse outcomes of adolescent deliveries. We also tested whether being married decreased the risk of adverse fetal outcomes in these adolescents. A 6-year retrospective register analysis. Buea Regional Hospital. Birth records from 2007 to 2012. None. Prevalence and 6-year trend in the rate of adolescent deliveries; adverse fetal outcomes. The overall prevalence of adolescent deliveries was 9.9% (491 of 4941). There was no significant change in the annual prevalence of adolescent deliveries over 6 years (P trend = .8). Adolescent pregnancies were at higher risk of preterm deliveries (deliveries at gestational age <37 completed weeks; odds ratio [OR], 1.7; 95% confidence interval [CI], 1.3-2.2; P < .01), low birth weight (defined as birth weight <2600 g; OR, 1.8; 95% CI, 1.4-2.3; P < .01), and neonatal asphyxia (OR, 1.4; 95% CI, 1.1-1.7; P < .01). There was no significant difference in the frequency of adverse outcomes between married and single adolescents. One of every 10 babies is born from adolescent mothers in the Buea Regional Hospital. Whether these mothers are married or not, their neonates are exposed to higher morbidity. This emphasizes the need for more adolescent-friendly public health policies geared toward reducing the prevalence of this condition to improve the chances of attaining the Millennium Development Goals in Cameroon.

    Background Adolescent pregnancies are a growing public health problem in Cameroon. We sought to study the outcome of such pregnancies, in order to inform public health action. Methods A cross-sectional analysis of 5997 deliveries which compared the outcome of deliveries in adolescent (10–19 years old) pregnant women registered at the Yaoundé Central Hospital between 2008 and 2010 to that of their non-adolescent adult (≥ 20 years old) counterparts. Variables used for comparison included socio-demographic and obstetric characteristics of parturients, referral status, and maternal and fetal outcomes. Predictors of maternal and of perinatal mortality were determined through binomial logistic modeling. Results Adolescent deliveries represented 9.3% (560) of all pregnancies registered. Adolescent pregnancies had significantly higher rates of both gestational duration extremes: preterm as well as post-term deliveries (29.3% versus 24.5%, p = 0.041 OR 1.28 95% CI 1.01-1.62 and 4.9 versus 2.4%, p = 0.014 OR 2.11 95% CI 1.46-3.87 respectively). Both groups did not differ significantly with respect to mean blood loss, rates of cesarean or instrumental deliveries. Adolescent deliveries however required significantly twice as many episiotomies (OR 2.15 95% CI 1.59-2.90). The likelihood of perineal tears in the adolescent group was significantly higher than that in the adult group on assuming episiotomies done would have been tears if they had not been carried out (OR 1.45 95% CI 1.16-1.82). Adolescent parturients had a higher likelihood of apparent fetal death at birth as well as perinatal fetal death after resuscitation efforts (AOR 1.75 95% CI 1.25-2.47 and AOR 1.69 95% CI 1.17-2.45 respectively).Comparisons of pregnancy outcomes between early (10–14 years), middle (15–17 years) and late adolescence (18–19 years) found no significant differences. Predictors of maternal death included having been referred, having had ≥5 deliveries and preterm

    Objectives Using cohort data nested in a randomized trial conducted in Cameroon, this study aimed to investigate time trends and predictors of the susceptibility to transmitting HIV during the first 24 months of treatment. Methods The outcome, susceptibility to transmitting HIV, was defined as reporting inconsistent condom use and experiencing incomplete virological suppression. Mixed logistic regressions were performed to identify predictors of this outcome among 250 patients reporting to have had sexual relationships either with HIV-negative or unknown HIV status partner(s). Results Despite an initial decrease from 76% at M0 to 50% at M6, the rate of inconsistent condom use significantly increased from M12 (59%) to M24 (66%) (p = 0.017). However, the proportion of patients susceptible to transmitting HIV significantly decreased over follow-up from 76% at M0, to 50% at M6, 31% at M12 and 27% at M24 (p<0.001). After controlling for age, gender and intervention group, we found that perceiving healthcare staff’s readiness to listen as poor (adjusted odds ratios (AOR) [95% Confidence Interval (CI)] = 1.87 [1.01–3.46]), reporting to have sexual relationships more than once per week (AOR [95%CI] = 2.52 [1.29–4.93]), having more than one sexual partner (AOR [95%CI] = 2.53 [1.21–5.30]) and desiring a/another child (AOR [95%CI] = 2.07 [1.10–3.87]) were all associated with a higher risk of being susceptible to transmitting HIV. Conversely, time since ART initiation (AOR [95%CI] = 0.66 [0.53–0.83] for an extra 6 months and ART adherence (AOR [95%CI] = 0.33 [0.15–0.72]) were significantly associated with a lower risk of being susceptible to transmitting HIV. Conclusions The decrease observed in the susceptibility to transmitting HIV suggests that fear of behavioural disinhibition should not be a barrier to universal access to ART. However, developing adequate preventive interventions matching patients’ expectations -like the desire

    his study presents the first and detail field investigations of exposed deposits at proximal sections of the Barombi Mbo Maar (BMM), NE Mt Cameroon, with the aim of documenting its past activity, providing insight on the stratigraphic distribution, depositional process, and evolution of the eruptive sequences during its formation. Field evidence reveals that the BMM deposit is about 126m thick, of which about 20m is buried lowermost under the lake level and covered by vegetation. Based on variation in pyroclastic facies within the deposit, it can be divided into three main stratigraphic units: U1, U2 and U3. Interpretation of these features indicates that U1 consists of alternating lapilli-ash-lapilli beds series, in which fallout derived individual lapilli-rich beds are demarcated by surges deposits made up of thin, fine-grained and consolidated ash-beds that are well-defined, well-sorted and laterally continuous in outcrop scale. U2, a pyroclastic fall-derived unit, shows crudely lenticular stratified scoriaceous layers, in which many fluidal and spindle bombs-rich lapilli-beds are separated by very thin, coarse-vesiculatedash-beds, overlain by a mantle xenolith- and accidental lithic-rich explosive breccia, and massive lapilli tuff and lapillistone. U3 displays a series of surges and pyroclastic fall layers. Emplacement processes were largely controlled by fallout deposition and turbulent diluted pyroclastic density currents under "dry" and "wet" conditions. The eruptive activity evolved in a series of initial phreatic eruptions, which gradually became phreatomagmatic, followed by a phreato-Strombolian and a violent phreatomagmatic fragmentation. A relatively long-time break, demonstrated by a paleosol between U2 and U3, would have permitted the feeding of the root zone or the prominent crater by the water that sustained the next eruptive episode, dominated by subsequent phreatomagmatic eruptions. These preliminary results require complementary studies, such as

    Background Genetic variation at loci influencing adult levels of HbF have been shown to modify the clinical course of sickle cell disease (SCD). Data on this important aspect of SCD have not yet been reported from West Africa. We investigated the relationship between HbF levels and the relevant genetic loci in 610 patients with SCD (98% HbSS homozygotes) from Cameroon, and compared the results to a well-characterized African-American cohort. Methods and Findings Socio-demographic and clinical features were collected and medical records reviewed. Only patients >5 years old, who had not received a blood transfusion or treatment with hydroxyurea were included. Hemoglobin electrophoresis and a full blood count were conducted upon arrival at the hospital. RFLP-PCR was used to describe the HBB gene haplotypes. SNaPshot PCR, Capillary electrophoresis and cycle sequencing were used for the genotyping of 10 selected SNPs. Genetic analysis was performed with PLINK software and statistical models in the statistical package R. Allele frequencies of relevant variants at BCL11A were similar to those detected in African Americans; although the relationships with Hb F were significant (p <.001), they explained substantially less of the variance in HbF than was observed among African Americans (∼ 2% vs 10%). SNPs in HBS1L-MYB region (HMIP) likewise had a significant impact on HbF, however, we did not find an association between HbF and the variations in HBB cluster and OR51B5/6 locus on chromosome 11p, due in part to the virtual absence of the Senegal and Indian Arab haplotypes. We also found evidence that selected SNPs in HBS1L-MYB region (HMIP) and BCL11A affect both other hematological indices and rates of hospitalization. Conclusions This study has confirmed the associations of SNPs in BCL11A and HBS1L-MYB and fetal haemoglobin in Cameroonian SCA patients; hematological indices and hospitalization rates were also associated with specific allelic variants.

    Severe malaria is a leading cause of morbidity and mortality in under-fives in sub-Saharan Africa. Recently quinine has been replaced by artesunate as the first-line drug in the treatment of severe malaria in Cameroon. Artesunate has been shown to be cost-effective in African children, but whether these findings are transferable to Cameroonian children remains to be explored. To conduct a cost-analysis of four different regimens used in the treatment from the perspective of the healthcare payer. An economic evaluation alongside a randomized comparative study was conducted in children aged 3 months to 15 years, admitted at the Ebolowa Regional Hospital with severe malaria due to Plasmodium falciparum. Patients were randomized to receive one of the four treatment alternatives. Group 1 (ARTES) received parenteral artesunate at 2.4 mg/kg at H0, H12, H24 and then once daily; Group 2 (QLD) received a loading dose of quinine base at 16.6 mg/kg followed 8 h later by an 8-hourly maintenance dose of 8.3 mg/kg quinine base; Group 3 (QNLD3) received 8.3 mg/kg quinine base every 8 h, and Group 4 (QNLD2) received 12.5 mg/kg quinine base every 12 h. The main outcome measure for effectiveness of treatment was the parasite reduction rate. Based on a healthcare perspective, an evaluation of direct medical costs was done, including costs of anti-malarials, nursing care materials, adjuvant treatment, laboratory investigations, hospitalisation and professional fees. Guided by a cost minimalization approach, the relative costs of these treatment alternatives was compared and reported. Overall cost was higher for ARTES group at $65.14 (95% CI $57.68-72.60) than for quinine groups ($52.49-$62.40), but the difference was not statistically significant. Cost of the anti-malarial drug was significantly higher for artesunate-treated patients than for quinine-treated patients, whereas cost of hospitalization was significantly lower for artesunate-treated patients than for quinine

    End-Stage Renal disease (ESRD) is associated with increased morbidity and mortality. We assessed the occurrence, time-trend and determinants of fatal outcomes of haemodialysis-treated ESRD patients over a 10-year period in a major referral hospital in Cameroon. Medical records of ESRD patients who started chronic haemodialysis at the Douala General Hospital between 2002 and 2012 were reviewed. Baseline characteristics and fatal outcomes on dialysis were recorded. Accelerated-failure time and logistic regression models were used to investigate the determinants of death. A total of 661 patients with 436 (66 %) being men were included in the study. Mean age at dialysis initiation was 46.3 ± 14.7 years. The median [25(th)-75(th) percentiles] duration on dialysis was 187 [34-754] days. A total of 297 (44.9 %) deaths were recorded during follow-up with statistical difference over the years (p < 0.0001 for year by year variation) but not in a linear fashion (p = 0.508 for linear trend), similarly in men and women (p = 0.212 for gender*year interaction). The death rate at 12 months of follow-up was 26.8 % (n = 177), with again similar variations across years (p < 0.0001). In all, 34 % of deaths occurred within the first 120 days. Year of study and background nephropathies were the main determinants of mortality, with the combination of diabetes and hypertension conveying a 127 % (95 % CI: 40-267 %) higher risk of mortality, relative to hypertension alone. Mortality in dialysis is excessively high in this setting. Because most of these premature deaths are potentially preventable, additional efforts are needed to offset the risk and maximise the benefits from the ongoing investments of the government to defray the cost of haemodialysis. Potential actions include sensitisation of the population and healthcare practitioners, early detection and referral of individuals with CKD; and additional subsidies to support the cost of managing co

    Accidental exposure to blood and body fluids is a public health concern, especially among health workers and constitutes a risk of transmission of blood-borne viruses including HIV, hepatitis B virus and hepatitis C virus. The objective of this study was to determine the frequency and the post exposure management of accidental exposures to blood and body fluid among health workers in the Yaoundé University Teaching Hospital. It was a cross-sectional hospital-based study conducted from the 1st to the 30th of September 2013. Self-administered questionnaires to health workers were used to collect data on self-reported accidents, circumstances and post-exposure management. Their knowledge on accidental exposure to blood was also assessed. Data were entered and analyzed using Epi Info software version 3.5.4. Descriptive analysis was performed to measure the importance of AEB and to evaluate the risk of contamination. One hundred and fifty health workers were interviewed among which 36.7 % reported having been exposed to blood and body fluid at least once in the preceding 3 months. Splash was the most reported injury (in 60.3 % of cases), followed by needle stick (28.7 %) and cuts (10.9 %). Moreover, 43.6 % of victims were not vaccinated against HBV, 7.3 % were not wearing gloves during the accident and 41 % of splash occurs on injured skin. The majority of victims belong to the surgical Department [20 %, p = 0.2310]. None of these injuries had been reported in the registry of accidental exposure to blood. There is a high rate of accidental exposure to blood and body fluid in the daily hospital routine. Preventives measures, including wearing of protective equipment's during care and vaccination against HBV are not systematically done among health workers. Health institution should develop and provide standard operating procedures targeting surveillance of occupational risks, staff training, and supervision.

    This study investigated the variations in some cells of the immune system, as well as the antibiotic resistance of the bacteria responsible for enteric infections among HIV+ patients compared to HIV- patients in Mbouda AD LUCEM Hospital, Cameroon. A cross-sectional study was performed from September 2014 to February 2015 in 67 human immunodeficiency virus (HIV)-seropositive (HIV+) and 37 HIV-seronegative (HIV-) patients. Blood collected from these patients was used to perform cluster of differentiation 4 (CD4) and cluster of differentiation 8 (CD8) lymphocyte blood counts and a white blood cell count, as well as to measure C-reactive protein (CRP) blood by flow cytometry and perform optical and immuno-turbidimetric detection. Enteric bacteria were isolated from the stool of patients, and their antibiotic susceptibility profiles were determined using agar diffusion methods. The results showed that Escherichia coli was the main pathogenic bacteria in the digestive tracts of HIV+ (85.3%) and HIV- (81.1%) patients, and infections with Klebsiella sp. were also predominant among HIV- patients (29.4%). Resistance of Klebsiella sp. to ceftriaxone (CRO; P=0.001), gentamicin (GEN; P=0.005), chloramphenicol (CHL; P=0.0004), ciprofloxacin (CIP; P=0.005) and doxycycline (DOX; P<0.0001) was significantly higher in HIV+ patients than in HIV- patients. Enterobacter sp. showed high resistance to GEN (P=0.009) and CIP (P=0.001) in HIV+ patients compared to HIV- patients. Citrobacter sp. was resistant to GEN (P=0.009) in HIV+ patients compared to HIV- patients. Salmonella sp. showed high resistance to CHL (P<0.0001) and DOX (P<0.0001) in HIV+ patients compared to HIV- patients. Resistance of Serratia sp. to AMO (P=0.005), AMC (P=0.005) and CHL (P=0.005) was significantly higher in HIV+ patients than in HIV- patients. Lymphopenia was higher in HIV+ patients (36.8%) than in HIV- patients (2.7%). In 45.9% of the HIV- patients, the CRP rate was higher than 6mg/L compared to 16.2% in HIV

    Objective. To determine the frequency of lipid abnormalities in patients with a cardiovascular risk and disease at the University Teaching Hospital (UTH) of Yaoundé. Materials and Methods. We conducted a cross-sectional study from 1 March to 31 May 2015 at the UTH of Yaoundé. We included all patients seen in the outpatient department with a diagnosis of a cardiovascular disease or a risk factor for cardiovascular disease. Patients who accepted to participate in the study were asked to answer a questionnaire; after that a blood sample was taken for lipid profile. An informed consent was signed by all the participants and the study has received approval from the national ethic committee. Results. We recruited 264 patients of which 119 were men and 145 were women with a sex ratio of 0.82. Mean age was 61.36 years. The frequency of lipid profiles abnormalities was as follows: low HDL cholesterol (44.3%), hypertriglyceridemia (18.9%), high LDL cholesterol (3.8%), and high total cholesterol 3.4%). Hypertriglyceridemia was strongly associated with type 2 diabetes mellitus. Conclusion. Low levels of HDL cholesterol and hypertriglyceridemia are more prevalent in our study population. More studies are needed to confirm this finding in our environment. PMID:28163932

    Congenital heart disease (CHD) is a common condition in children in Sub-Saharan Africa (SSA), where it is associated with poor outcomes. Diagnosis of CHD in SSA depends essentially on echocardiography, which is available only in few urban referral centers. Our aim was to assess time changes in the pattern of referral for pediatric echocardiography and the subsequent diagnosis of structural CHD in a major SSA city. All pediatric echocardiography performed between 2004 and 2013 at the echocardiography laboratory of the Yaounde General Hospital were reviewed. The primary indication of the study and the presence of structural CHD were recorded. Between 2004 and 2013, 9,390 echocardiograms were performed and 834 (8.9%) children aged 1 day to 15 years underwent echocardiography at the center, and 227 (27.2%) cases of definite structural CHD were diagnosed, with 123 (54.2%) in boys. The most frequent indications for echocardiography were heart murmurs (40%) and the suspicion of CHD (37.4%). The commonest CHD was ventricular septal defect (VSD) (30%) with tetralogy of Fallot being the most frequent cyanotic heart lesion (5.3%). The proportion of pediatric echocardiography decreased from 13.3% in 2004-2005 to 6.1% in 2012-2013 (P=0.001) but not in a linear fashion (P=0.072 for linear trend).The diagnosis of structural CHD increased from 25.1% in 2004-2005 to 27.1% in 2012-2013. This increase however was non-significant (P=0.523) and did not follow a linear trend (P=0.230). The pattern of referral for pediatric echocardiography at this center has changed over time, but diagnosis of structural CHD has remained the same. Improving access to this diagnostic procedure and subsequent treatment of diagnosed CHD will help improving the outcome of the disease in this setting.

    Background Congenital heart disease (CHD) is a common condition in children in Sub-Saharan Africa (SSA), where it is associated with poor outcomes. Diagnosis of CHD in SSA depends essentially on echocardiography, which is available only in few urban referral centers. Our aim was to assess time changes in the pattern of referral for pediatric echocardiography and the subsequent diagnosis of structural CHD in a major SSA city. Methods All pediatric echocardiography performed between 2004 and 2013 at the echocardiography laboratory of the Yaounde General Hospital were reviewed. The primary indication of the study and the presence of structural CHD were recorded. Results Between 2004 and 2013, 9,390 echocardiograms were performed and 834 (8.9%) children aged 1 day to 15 years underwent echocardiography at the center, and 227 (27.2%) cases of definite structural CHD were diagnosed, with 123 (54.2%) in boys. The most frequent indications for echocardiography were heart murmurs (40%) and the suspicion of CHD (37.4%). The commonest CHD was ventricular septal defect (VSD) (30%) with tetralogy of Fallot being the most frequent cyanotic heart lesion (5.3%). The proportion of pediatric echocardiography decreased from 13.3% in 2004–2005 to 6.1% in 2012–2013 (P=0.001) but not in a linear fashion (P=0.072 for linear trend).The diagnosis of structural CHD increased from 25.1% in 2004–2005 to 27.1% in 2012–2013. This increase however was non-significant (P=0.523) and did not follow a linear trend (P=0.230). Conclusions The pattern of referral for pediatric echocardiography at this center has changed over time, but diagnosis of structural CHD has remained the same. Improving access to this diagnostic procedure and subsequent treatment of diagnosed CHD will help improving the outcome of the disease in this setting. PMID:28164029

  12. Assessing forest products usage and local residents' perception of environmental changes in peri-urban and rural mangroves of Cameroon, Central Africa

    2011-01-01

    Background Deforestation is one of the most ubiquitous forms of land degradation worldwide. Although remote sensing and aerial photographs can supply valuable information on land/use cover changes, they may not regularly be available for some tropical coasts (e.g., Cameroon estuary) where cloud cover is frequent. With respect to mangroves, researchers are now employing local knowledge as an alternative means of understanding forest disturbances. This paper was primarily aimed at assessing the mangrove forest products usage, along with the local people's perceptions on environmental changes, between Littoral (Cameroon estuary) and Southern (mouth of the Nyong River and Mpalla village) regions of Cameroon. Methods The data from both locations were obtained through conducting household interviews and field observations. Results In the Cameroon estuary (Littoral region), 69.23% of respondents (mostly elders) could distinguish two to four mangrove plants, whereas the informants (65.45%) in the mouth of the Nyong River and Mpalla village (mostly young people interviewed from the Southern region) are familiar with only one or two commonly found mangroves. Also, more respondents from the Cameroon estuary are depending on mangroves for fuelwood (Rhizophora spp.) and housing (Rhizophora spp., Avicennia germinans (L.) Stearn and Nypa fruticans (Thumb.) Wurmb.) purposes, in contrast to Nyong River mouth and Mpalla village. Although local people perceived wood extraction as a greater disruptive factor, there are several causes for mangrove depletion in the Cameroon estuary. Among others, over-harvesting, clear-felled corridors, sand extraction and housing were found important. Furthermore, a decline in mangrove fauna composition (in terms of fishery products) was recorded in the Littoral as well as Southern regions. However, the causes of such perceived negative changes were not similar in both cases. Conclusions Findings of this study highlight the need to improve sustainable

    Background Children’s health programs in Sub-Saharan Africa have always been oriented primarily to infectious diseases and malnutrition. We are witnessing in the early 21st century an epidemiological transition marked by the decline of old diseases and the identification of new diseases including heart disease. Therefore, it is necessary to describe the spectrum of these diseases in order to better prepare health workers to these new challenges. Methods We conducted a cross-sectional study focused on heart disease diagnosed by echocardiography in children seen from January 2006 to December 2014 in a pediatric hospital of Yaounde. We collected socio-demographic data and the types of heart disease from registers, patients files as well as the electronic database of echocardiographic records. Results A total of 2,235 patients underwent echocardiographic examination during the study period including 1,666 subjects with heart disease. Congenital cardiopathies were found in 1,230 (73.8%) patients and acquired abnormalities in 429 (25.8%). Seven children (0.4%) had a combination of both types. Congenital heart defects (CHD) were dominated by ventricular septal defect (VSD). Acquired heart disease was mostly rheumatic valvulopathies. Dyspnea on exertion was the most frequent presenting complaint (87.6%). Discovery of a heart murmur was the principal clinical finding on physical examination (81.4%). The median age was 9 months for congenital heart disease and 132 months for acquired heart disease. Conclusions As infectious diseases recede and the diagnostic facilities are improving, pediatric heart diseases occupy a more important position in the spectrum of pediatric diseases in our context. However, the ability to evoke the diagnosis remains unsatisfactory by the majority of health personnel and therefore needs to be improved. Apart from congenital heart diseases, the impact of acquired heart diseases, rheumatic valvulopathy being the highest ranking, is remarkable in

    The Mbengwi plutonics consist of intermediate to felsic granitoids forming a continuous magmatic series from monzonite to granite and mafic intrusions. Their mineralogical composition consists of quartz, plagioclases, K-feldspars, biotite, muscovite, and amphibole. The accessory phase includes opaque minerals + titanite ± apatite ± zircon, while secondary minerals are pyrite, phengite, chlorite, epidote, and rarely calcite. These plutonics are assigned high-K calc-alkaline to shoshonitic series, metaluminous to weakly peraluminous and mostly belong to an I-type suite (A/CNK = 0.63-1.2). They are typically post-collisional, with a subduction signature probably being inherited from their protoliths emplaced during the subduction phase. The Sr and Nd isotopic data evidence that these plutonics result from melting of the lower continental crust with variable contribution of the oceanic crust. Their geochemical features are similar to those of western Cameroon granitoids related to the Pan-African D1 event in Cameroon.

    The geomagnetic data obtained from Amber Network station in Cameroon has been used for this study. The variability of H component of geomagnetic field has been examined by using geomagnetic field data of X and Y components recorded at AMBER magnetometer station hosted by the Department of Physics of University of Yaoundé (3.87°N, 11.52°E). The day-to-day variability of the horizontal intensity of the geomagnetic field has been examined and shows that the scattering of H component of magnetic field variation is more on disturbed than on quiet days. The signatures H of geomagnetic Sq and Sd variations in intensities in the geomagnetic element, has been studied. This paper shows that the daytime variations in intensities of geomagnetic elements H, Sq(H) and Sd(H) respectively are generally greater at diurnal-times than at night-times. This study mainly interests to answer to two questions: 1) how can geomagnetic variations be used to study the equatorial ionosphere electrodynamics and electrojet equatorial over Africa in general and Cameroon in particular? 2) How can geomagnetic variations be used to monitor and predict Space weather events in Cameroon? This study presents and interprets the results of H component of geomagnetic field variations during magnetic storms and on quiet days.

    We compared catheter survival and sepsis rates in a tertiary paediatric gastroenterology centre with those at home in the same patients. We examined whether there were differences in the safety in the two locations, and estimated the financial and opportunity cost implications of any difference. We used survival analysis to analyse differences. Surgical records were audited to determine venous access workload, and to estimate cost implications. Twenty patients with chronic intestinal failure but stable parenteral nutrition requirements, ranging from 0.04-15.83 years of age were studied. The duration of line survival and sepsis-free intervals and rates of re-operation for venous access were determined to estimate morbidity and costs. The study encompassed 28 patient-years in hospital and 48 patient-years at home. There was a significant reduction in the rate of sepsis at home compared with hospital (Z = 4.30, P < 0.00001), and a similar improvement in line survival (Z = 4.36, P < 0.00001). Line insertions accounted for 21% of minor surgery in our hospital, one third being reinsertions. We conclude that central venous catheter sepsis rates are greatly improved at home. If home results could be achieved in the hospital setting, considerable cost savings would be made.

    To evaluate the impact of implementing a multifaceted intervention based on the WHO Pocketbook of Hospital Care for Children on the quality of case management of common childhood illnesses in hospitals in Lao PDR. The quality of case management of four sentinel conditions was assessed in three central hospitals before and after the implementation of the WHO Pocketbook as part of a broader mixed-methods study. Data on performance of key steps in case management in more than 600 admissions were collected by medical record abstraction pre- and post-intervention, and change was measured according to the proportion of cases which key steps were performed as well as an overall score of case management for each condition. Improvements in mean case management scores were observed post-intervention for three of the four conditions, with the greatest change in pneumonia (53-91%), followed by diarrhoea and low birthweight. Rational drug prescribing, appropriate use of IV fluids and appropriate monitoring all occurred more frequently post-intervention. Non-recommended practices such as prescription of antitussives became less frequent. A multifaceted intervention based on the WHO Pocketbook of Hospital Care for children led to better paediatric care in central Lao hospitals. The degree of improvement was dependent on the condition assessed. © 2014 John Wiley & Sons Ltd.

    Haemodialysis is one of the widely used methods in end stage renal disease. However it has a negative impact on the quality of life of the renal patients. Hypoalbuminaemia occur in haemodialysis patients and it correlates strongly with mortality and morbidity. We sought out to determine the prevalence of hypoalbuminaemia among haemodialysis patients at Parirenyatwa group of hospitals and Chitungwiza central hospital. A questionnaire was administered on haemodialysis patients at Parirenyatwa Group of Hospitals and Chitungwiza Central Hospital who consented to participate in the study. Pre dialysis serum samples collected from the patients were used for albumin analysis. The serum from the patients was analysed for serum albumin levels using the Mindray BS120 chemistry analyser using the bromocresol green method. A total of 60 patients were recruited from the two hospitals. The Mean albumin concentration for the entire group was 33.6g/L SD (6.1 g/L). The mean albumin in males was 33.6 g/L, SD (5.9) and in female 33.6, SD (6.6 g/L) and this was not statistically significantly different (p = 0.988). The prevalence of hypoalbuminaemia was 76.7%. Hypoalbuminaemia in 76.7% of haemodialysis patients studied is a cause of concern thus monitoring of haemodialysis patients albumin is necessary since its decreased levels has been associated with increased morbidity and mortality.

    Heterotopic pregnancy is very rare under natural circumstances. We report the case of a 28 year old Gravida2 Para1001 woman at 9 weeks of pregnancy who consulted in emergency for acute pelvic pain following metrorrhagia. Physical exam revealed hemoperitoneum without shock. An emergency ultrasonography revealed two gestational sacs, one intra-uterine and the other extra-uterine. Laparotomy was done and the findings were: a ruptured right tubal pregnancy with 1,300 milliliters of hemoperitoneum, type B left utero-adnexal adhesions and an increased uterus consistent with a 9 weeks pregnancy. Right total salpingectomy was done and the patient did well postoperatively. That intrauterine pregnancy evolved normally under progesterone supply and the woman delivered a termed live female baby weighing 3.1 kilogrammes. In our context where ultrasound is not always available, practitioners carrying out salpingectomy for ruptured ectopic pregnancies should bear in mind the plausibleness of heterotopic pregnancy in order to properly handle the uterus.

    The author describes the circumstances of the hospital and out-of-hospital situation in the region she worked in, in focussing on the relevant practical features of the daily life of patients and staff. She deals among other things with the maternity ward (including the separate "camp" devoted to prenatal stays) and the operating theatre. As regards health activities outside the hospital, she mentions those of the existing health centres and of auxiliary personnel called first-aiders (whose job description is close to the one of the village health workers advocated by WHO and others). A health team, usually led by a physician, makes periodic visits to bush villages. The importance of the contacts thus created, for health work itself (including collaboration with traditional health practitioners) as well as for community development, is underlined.

    HIV and AIDS are major public health problems in Cameroon where the HIV prevalence is 5.5%. Candidiasis is the leading opportunistic mycosis in HIV and AIDS patients. The objective of this study was to determine the in vitro antifungal susceptibility pattern of Candida albicans in HIV and AIDS patients to eight antifungal agents in the Nylon Health District of Douala in Cameroon. Three hundred and four HIV and AIDS patients were recruited between March and August 2007 to participate in a cross-sectional study. All subjects who fulfilled the inclusion criteria were enrolled. Informed consent was obtained from all subjects before samples were collected. Three samples comprising oral swabs, vagina/urethra swabs and a mid-stream urine were collected from each subject. Specimens were cultured on sabouraud dextrose agar and C. albicans isolates were identified using the germ tube technique. The disk diffusion method was used for antifungal susceptibility testing using eight antifungal agents. The prevalence of candidiasis in the study population was 67.8% (95% CI: 62.5-73.1%) and that of C. albicans was 42.8% (95% CI: 37.2-48.4%). Oral swabs had the highest prevalence of C. albicans followed by vaginal/urethral samples (52.6% vs. 29.7% respectively). Forty (30.8%) subjects had C. albicans infection at more than one collection site. There was a statistically significant difference in the infectivity of C. albicans with age, sex and site of infection (P<0.05). C. albicans isolates were most sensitive to ketoconazole (80%) followed by econazole (64.6%) while fluconazole and 5-flurocytosin recorded the poorest sensitivities (22.9% vs 24.6%, respectively). There was a statistically significant difference in the sensitivity pattern of antifungal agents with respect to the site of isolation of the organism (P<0.05). Ketoconazole is the drug of choice for the treatment of C. albicans infection in HIV and AIDS patients in the Nylon Health District of Douala, Cameroon.

    The Bambouto Mountain is a shield volcano, that lies between Longitudes 10^o and 10^o10'E and the Latitudes 5^o35' and 5^o45'N. It is part of the Cameroon Volcanic Line, and lies in the NE linear axis to Mts Cameroon and Manengouba. It is elliptic (45-50 km X 20-25 km) and bears two collaspsed calderas at its summit. Volcanic activity of this volcano is in three dynamism: an effusive volcanic activity, that at the origin of lava flow (basanite, basalt, hawaiite, benmoréite, trachyte, tephrite,...), an extrusive phase responsible of the formation of trachytic, phonolitic and rarely basaltic domes. Lastly an explosive phase which gave rise to strombolian ejecta and several ignimbritic sheets. Ignimbrites are common and occur as discontinuous sheets 10-30 m thick, at times up to 100 m. These ignimbrites are various, ranging from tuffaceous facies which are more or less rich in lithic fragments to compact. trachyto-rhyolitic facies. Thin sections of these ignimbrites show full or partly cracked alkali feldspars, plagioclase, biotite, clinopyroxenes, trachyte fragments and entirely deformed flames, devitrified or partly altered in a devitrified matrix. They also enclosed xenoliths of granito-gneissic basement rocks, trachytes, scoria and carbonaceous rocks (lignite and/or carbonised wood). These ignimbritic elements are not found in all facies (Gountie Dedzo, 2002). In addition, the different ignimbritic facies, present degrees of welding depending on outcrop locality or on stratigraphic position in the eruption episode. Hand specimen and thin section studies indicate different welding rates and compaction depend on the emission source of the tephras, emission temperature and intensity of the eruption. Following the afore mentioned and description of proposed geological cross-section, they exist many volcanic phases and ignimbritic emissions in the Bamboutos Mountain.

    Despite the recent international focus on maternal and child nutrition, little attention is paid to nutrition capacity development. Although infant feeding counselling by health workers increases caregivers' knowledge, and improves breastfeeding, complementary feeding, and children's linear growth, most of the counselling in sub-Saharan Africa is primarily conducted by nurses or volunteers, and little is done to develop capacity for nutrition at the professional, organizational, or systemic levels. The Cameroon Baptist Convention Health Services Nutrition Improvement Program (NIP) has integrated a cadre of nutrition counselors into prevention of mother-to-child transmission of HIV programs, infant welfare clinics, and antenatal clinics to improve infant and young child feeding practices (IYCF). The study objective was to evaluate the effects of NIP's infant feeding counselors on exclusive breastfeeding (EBF), complementary feeding (CF), and children's linear growth. A cross-sectional evaluation design was used. Using systematic random sampling, caregivers were recruited from NIP sites (n = 359) and non-NIP sites (n = 415) from Infant Welfare Clinics (IWCs) in the Northwest (NWR) and Southwest Regions (SWR) of Cameroon between October 2014 and April 2015. Differences in EBF and CF practices and children's linear growth between NIP and non-NIP sites were determined using chi-square and multiple logistic regression. After adjusting for differences in religion, occupation, and number of months planning to breastfeed, children were almost seven times (Odds Ratio [OR]: 6.9; 95% Confidence Interval [CI]: 2.30, 21.09; β = 1.94) more likely to be exclusively breastfed at NIP sites compared to non-NIP sites. After adjusting for differences in occupation, religion, number of months planning to breastfeed, rural environment, economic status, attending other Infant Welfare Clinics, and non-biological caregiver, children were five times (OR: 5.5; CI: 3.37, 9.02;

    Ultramafic xenoliths (lherzolite, harzburgite and olivine websterite) have been discovered in basanites close to Ngaoundéré in Adamawa plateau. Xenoliths exhibit protogranular texture (lherzolite and olivine websterite) or porphyroclastic texture (harzburgite). They are composed of olivine Fo89-90, orthopyroxene, clinopyroxene and spinel. According to geothermometers, lherzolites have been equilibrated at 880-1060 °C; equilibrium temperatures of harzburgite are rather higher (880-1160 °C), while those of olivine websterite are bracketed between 820 and 1010 °C. The corresponding pressures are 1.8-1.9 GPa, 0.8-1.0 GPa and 1.9-2.5 GPa, respectively, which suggests that xenoliths have been sampled respectively at depths of 59-63 km, 26-33 km and 63-83 km. Texture and chemical compositional variations of xenoliths with temperature, pressure and depth on regional scale may be ascribed to the complex history undergone by the sub-continental mantle beneath the Adamawa plateau during its evolution. This may involve a limited asthenosphere uprise, concomitantly with plastic deformation and partial melting due to adiabatic decompression processes. Chemical compositional heterogeneities are also proposed in the sub-continental lithospheric mantle under the Adamawa plateau, as previously suggested for the whole Cameroon Volcanic Line.

    A study of the spatial and temporal changes in the pattern and distribution of tropical wetland vegetation in four ponds that received sewage and wastewater discharge, was undertaken for a small wetland ecosystem in the Olezoa drainage basin in Yaounde, Cameroon. More than 25 years of nutrient loading has led to the eutrophication and subsequent establishment of wetland vegetation in these ponds. Estimated free water surface areas of the ponds in 1964, 1976, and 1986 and 1992 determined from digitized aerial photographs and field measurements suggests a decline of 70 to 100% in the pond surface areas due to invasion and colonization by plants. The rate of pond surface decline and vegetation development is correlated with the construction of sewage plants and the discharge of untreated sewage and wastewater into the ponds. The main wetland plants that are established in the ponds consist of aquatic species Nymphae lotus, Enhydra fluctuants, Pistia stratiotes, Commelina sp., Ipomea aquatica and terrestrial species Echinochloa sp., Thalia welwitschii, Polygonum senegalense, Leersia haxandra and Cyperus papyrus. The pattern of wetland plant succession that resulted within each pond is correlated to the timing, duration and magnitude of sewage and wastewater discharge into the wetland complex.

  10. Reconstructing C3 and C4 vegetation cover using n-alkane carbon isotope ratios in recent lake sediments from Cameroon, Western Central Africa

    Trees and shrubs in tropical Africa use the C3 cycle as a carbon fixation pathway during photosynthesis, while grasses and sedges mostly use the C4 cycle. Leaf-wax lipids from sedimentary archives such as the long-chain n-alkanes (e.g., n-C27 to n-C33) inherit carbon isotope ratios that are representative of the carbon fixation pathway. Therefore, n-alkane δ13C values are often used to reconstruct past C3/C4 composition of vegetation, assuming that the relative proportions of C3 and C4 leaf waxes reflect the relative proportions of C3 and C4 plants. We have compared the δ13C values of n-alkanes from modern C3 and C4 plants with previously published values from recent lake sediments and provide a framework for estimating the fractional contribution (areal-based) of C3 vegetation cover (fC3) represented by these sedimentary archives. Samples were collected in Cameroon, across a latitudinal transect that accommodates a wide range of climate zones and vegetation types, as reflected in the progressive northward replacement of C3-dominated rain forest by C4-dominated savanna. The C3 plants analysed were characterised by substantially higher abundances of n-C29 alkanes and by substantially lower abundances of n-C33 alkanes than the C4 plants. Furthermore, the sedimentary δ13C values of n-C29 and n-C31 alkanes from recent lake sediments in Cameroon (-37.4‰ to -26.5‰) were generally within the range of δ13C values for C3 plants, even when from sites where C4 plants dominated the catchment vegetation. In such cases simple linear mixing models fail to accurately reconstruct the relative proportions of C3 and C4 vegetation cover when using the δ13C values of sedimentary n-alkanes, overestimating the proportion of C3 vegetation, likely as a consequence of the differences in plant wax production, preservation, transport, and/or deposition between C3 and C4 plants. We therefore tested a set of non-linear binary mixing models using δ13C values from both C3 and C4

    One risk factor for infant and childhood morbidity is not exclusive breastfeeding (EBF) during the first six months of life. Entertainment Education (EE) is a communication strategy consisting of placing educational information into television, movies, and radio programs. In developing countries this form of behavioral change communication has proven effective in addressing health-related issues; however, no research has determined if EE is effective in promoting EBF. The objective of this research was to develop an EE audio program and discussion guide and to determine if a series of four 15-minute episodes and post-listening discussion improved knowledge, perceived benefits, self-efficacy, and intention and decreased misconceptions and perceived barriers toward EBF in the Kumbo West Health District, Cameroon. Pregnant women and their partners were assigned to either the control group (N = 116; 74 women, 42 partners) or intervention group (N = 148; 99 women, 49 partners) based on expected date of delivery. All control and intervention group participants completed a questionnaire prior to listening to the first and after the last episode. Pre- and post-listening questionnaires were used to determine changes in the EBF knowledge, misconceptions, perceived barriers, self-efficacy, and intention variables as a result of exposure to the audio program. The Wilcoxon Sign Rank test showed significant improvement in all of the variables, except perceived barriers, within the intervention group (p < 0.05) and the Mann-Whitney test indicated significant differences between the control and intervention group in all of the variables (p < 0.05), indicating that using an audio program and discussion guide based on the EE model is an effective tool for promoting EBF in this setting. The strength of this approach is that it goes beyond simply telling women about what constitutes EBF, but addresses misconceptions and perceived barriers that may prevent women from practicing EBF for

    Background Immunochromatographic card test (ICT) is a tool to map the distribution of Wuchereria bancrofti. In areas highly endemic for loaisis in DRC and Cameroon, a relationship has been envisaged between high L. loa microfilaria (Mf) loads and ICT positivity. However, similar associations have not been demonstrated from other areas with contrasting levels of L. loa endemicity. This study investigated the cross-reactivity of ICT when mapping lymphatic filariasis (LF) in areas with contrasting endemicity levels of loiasis and mansonellosis in Cameroon. Methodology/Principal Findings A cross-sectional study to assess the prevalence and intensity of W. bancrofti, L. loa and M. perstans was carried out in 42 villages across three regions (East, North-west and South-west) of the Cameroon rainforest domain. Diurnal blood was collected from participants for the detection of circulating filarial antigen (CFA) by ICT and assessment of Mf using a thick blood smear. Clinical manifestations of LF were also assessed. ICT positives and patients clinically diagnosed with lymphoedema were further subjected to night blood collection for the detection of W. bancrofti Mf. Overall, 2190 individuals took part in the study. Overall, 24 individuals residing in 14 communities were tested positive by ICT, with prevalence rates ranging from 0% in the South-west to 2.1% in the North-west. Lymphoedema were diagnosed in 20 individuals with the majority of cases found in the North-west (11/20), and none of them were tested positive by ICT. No Mf of W. bancrofti were found in the night blood of any individual with a positive ICT result or clinical lymphoedema. Positive ICT results were strongly associated with high L. loa Mf intensity with 21 subjects having more than 8,000 L. loa Mf ml/blood (Odds ratio = 15.4; 95%CI: 6.1–39.0; p < 0.001). Similarly, a strong positive association (Spearman’s rho = 0.900; p = 0.037) was observed between the prevalence of L. loa and ICT positivity by area

    A rational primary health care (PHC) health system could manage Cameroon's major health problems (e.g., tropical parasitic and deficiency diseases). In 1989, Cameroon's Ministry of Public Health (MOPH) implemented a district health system composed of a network of integrated health centers and the district referral hospital. In 1991 in the South West and North West Provinces, a study was conducted to examine the organization and functioning of the basic health centers. Health centers within or near urban areas had more staff than those in rural areas (mean, 13 vs. 3). The range of staff in urban areas was 1-50. Some health centers had no trained staff. Other health centers originally had about 7 trained staff and now have 1-2 trained staff as a result of widespread and uncoordinated transfers. Many highly-qualified and state registered nurse-midwives worked in urban maternal and child health (MCH) units. MCH activities (prenatal care, well-baby clinics, vaccinations, and sometimes family planning) comprised the minimum package of activities to be offered by all integrated health centers. More than 80% of the highly-trained midwives in the MCH units were wives of highly-placed civil servants or other members of the elite. These women apparently work in MCH units because, when compared to hospitals, there is a lighter work load and no night shifts. MOPH guidelines on personnel requirements have never been implemented. Had they been implemented, this unequal distribution of health workers would have been prevented. The World Health Organization calls for the abolition of specialized units, such as the MCH units, and for the establishment of health centers delivering PHC in well-defined areas. MOPH should clearly delineate the urban PHC policy for Cameroon, issue new directives for personnel deployment, and establish hardship incentives for personnel working in difficult areas.

    As the overwhelming surgical burden of injury and disease steadily increases, disproportionately affecting low- and middle-income countries, adequate surgical and trauma care systems are essential. Yet, little is known about the emergency and essential surgical care (EESC) capacity of facilities in many African countries. The objective of this study was to assess the EESC capacity in different types of hospitals across Cameroon. This cross-sectional survey used the WHO Tool for Situational Analysis to Assess EESC, investigating four key areas: infrastructure, human resources, interventions, and equipment and supplies. Twelve hospitals were surveyed between August and September 2009. Facilities were conveniently sampled based on proximity to road traffic and sociodemographic composition of population served in four regions of Cameroon. To complete the survey, investigators interviewed heads of facilities, medical advisors, and nursing officers and consulted hospital records and statistics at each facility. Seven district hospitals, two regional hospitals, two general hospitals, and one missionary hospital completed the survey. Infrastructure for EESC was generally inadequate with the largest gaps in availability of oxygen concentrator supply, an on-site blood bank, and pain relief management guidelines. Human resources were scarce with a combined total of six qualified surgeons, seven qualified obstetrician/gynecologists, and no anesthesiologists at district, regional, and missionary hospitals. Of 35 surgical interventions, 16 were provided by all hospitals. District hospitals reported referring patients for 22 interventions. Only nine of the 67 pieces of equipment were available at all hospitals for all patients all of the time. Severe shortages highlighted by this survey demonstrate the significant gaps in capacity of hospitals to deliver EESC and effectively address the increasing surgical burden of disease and injury in Cameroon. This data provides a foundation

    Our objective was to estimate the incidence of influenza-associated hospitalizations and in-hospital deaths in Central American Region. We used hospital discharge records, influenza surveillance virology data, and population projections collected from Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua to estimate influenza-associated hospitalizations and in-hospital deaths. We performed a meta-analysis of influenza-associated hospitalizations and in-hospital deaths. The highest annual incidence was observed among children aged <5 years (136 influenza-associated hospitalizations per 100 000 persons). Annually, 7 625-11 289 influenza-associated hospitalizations and 352-594 deaths occurred in the subregion. Our results suggest that a substantive number of persons are annually hospitalized because of influenza. Health officials should estimate how many illnesses could be averted through increased influenza vaccination. © 2016 The Authors.

    Located at the bottom of the Gulf of Guinea, Cameroon is exposed to a large variety of natural hazards, including volcanism. Most of the hazard are concentrated around the active volcano Mt. Cameroon which combines effusive and explosive types of activity. The threatened stakes are numerous and different exposed: people, settlements, industrial plantations, petrol refinery and many other factories and infrastructures. Until 2005, no risk management plans has been available. In 2006, the French Embassy in Cameroon, within the framework of a financial convention between Cameroon and France, put in place the GRINP (Management of Natural Risks and Civil Protection) project whose objective was to reinforce the capacity of Cameroon's civil protection department and thus, contribute to the improvement of the security of the population faced with catastrophes. The objective was to realize a Risk Prevention Plan at a local council scale, and taking into consideration the specific natural risks of each zone. The general objective of the RPP was to clearly draw land use maps for risks zones, showing the overlay of stakes with risk of different intensities. In 2008 European Commission funded the Mia-Vita project (Mitigating and Assessing Volcanic Impacts on Terrain and human Activities). The aim of the project is to improve the crisis management capabilities based on monitoring and early warning systems and secure communications; reduction of people's vulnerability and development of recovering capabilities after an event occurs for both local communities and ecological systems.

    The Tcholliré massif, in central north Cameroon, consists of elongated granite plutons that crop out along the Pan-African Tcholliré-Banyo shear zone (TBSZ), a potential suture zone within the Central Africa Orogenic Belt. New structural and geochronological data on these granites constrain the tectonic regime and timing of the TBSZ. The plutons consist of syntectonic granites and granodiorite containing dioritic mafic enclaves. They show an S2 sub-vertical foliation, that trends NE-SW to ENE-WSW. The related L2 lineation is subhorizontal to shallowly plunging to the SW or NE. Kinematic indicators such as asymmetric folds, sigmoidal-shape boudins, shear bands, imbricated feldspar phenocrysts along antithetic fractures point to a sinistral sense of shear. Microstructural analysis shows that structures are acquired from the submagmatic to the low temperature solid state suggesting progressive deformation of the magma during its emplacement, crystallization and cooling. U-Pb zircon dating on this massif yields emplacement ages of 719 ± 12 Ma for the biotite-amphibole granite and muscovite granite, 652.2 ± 5.4 Ma for the biotite-granite and 632 ± 13 Ma for the leucogranite. These geochronological data show in addition, Palaeoproterozoic inherited ages of 1631 ± 30 Ma on the leucogranites of this massif, and point to a Palaeoproterozoic contribution in their genesis. The range of ages (ca. 87 Ma) points to the timing of syntectonic emplacement of felsic magmas coeval with sinistral transpression along the TBSZ during the Pan-African orogeny. These results show that the TBSZ has recorded prolonged deformation associated with crustal magmatism between the Palaeoproterozoic Adamawa-Yadé domain to the southeast and the Sinassi-Mayo Kebbi Neoproterozoic magmatic arc to the Northwest.

    Task shifting to nurses for antiretroviral therapy (ART) is promoted by the World Health Organization to compensate for the severe shortage of physicians in Africa. We assessed the effectiveness of task shifting from physicians to nurses in rural district hospitals in Cameroon. We performed a cohort study using data from the Stratall trial, designed to assess monitoring strategies in 2006-2010. ART-naive patients were followed up for 24 months after treatment initiation. Clinical visits were performed by nurses or physicians. We assessed the associations between the consultant ratio (ie, the ratio of the number of nurse-led visits to the number of physician-led visits) and HIV virological success, CD4 recovery, mortality, and disease progression to death or to the World Health Organization clinical stage 4 in multivariate analyses. Of the 4141 clinical visits performed in 459 patients (70.6% female, median age 37 years), a quarter was task shifted to nurses. The consultant ratio was not significantly associated with virological success [odds ratio 1.00, 95% confidence interval (CI): 0.59 to 1.72, P = 0.990], CD4 recovery (coefficient -3.6, 95% CI: -35.6; 28.5, P = 0.827), mortality (time ratio 1.39, 95% CI: 0.27 to 7.06, P = 0.693), or disease progression (time ratio 1.60, 95% CI: 0.35 to 7.37, P = 0.543). This study brings important evidence about the comparability of ART-related outcomes between HIV models of care based on physicians or nurses in resource-limited settings. Investing in nursing resources for the management of noncomplex patients should help reduce costs and patient waiting lists while freeing up physician time for the management of complex cases, for mentoring and supervision activities, and for other health interventions.

  20. The effect of centralized hospital administration on financial control and hospital service delivery: the case of Hong Kong.

    PubMed

    1987-01-01

    Administration, financial control and service delivery are three mutually influential dimensions of a hospital system. The centralized hospital system of Hong Kong is a case-in-point that illustrates such influence. By spending only a small fraction of the Gross Domestic Product each year, the government has been able to provide limited modern health care services at nominal financial cost to the public. At the same time, hospitals are subject to a strict system of administrative and financial controls. Consequently, Hong Kong hospitals must utilize their limited facilities effectively to provide modern health services to the public. However, the trade-off between low-cost health services and limited facilities is the incurrence, by the public, of non-monetary costs in obtaining hospital admission.

    The Mbéré sub-basin belongs to the Mbéré-Djerem intra-continental basin of Central North Cameroon. In this sub-basin, a travertine outcrop has been discovered and investigated palynologically and petrologically in this study. The sporopollinic content of the studied travertine is mainly composed of fungal spores (Rhyzophagites sp., Monoporisporites sp …) associated with rare fresh water algae spores such as Chomotriletes minor and angiosperm pollens (compositae, graminae, …). This sporopollinic association is indicative of hot and semi-arid to arid paleoclimate and reveals a Pleistocene-Holocene depositional age. The whole rock major element geochemistry shows relative enrichment of CaO (49.48%) and CO2 (38.49%). The origin of CO2 is probably from magmatic and/or metamorphic fluids. Compared to other travertines, SiO2 and Al2O3 contents are significant with average concentrations of 5.68% and 2.58% respectively. The mineralogical composition revealed by a microscopic study of bulk rocks is dominated by calcite (90-92%) associated to quartz (2-4%) and feldspar (2-3%), meanwhile the heavy mineral concentrate is formed by various mineral types such as zircon (most abundant), garnet, tourmaline, epidote, biotite, peridot and aegirine augite suggesting that the underground water has crossed both volcanic, plutonic and metamorphic rocks. With the mineral composition made of both chemical and detrital derived elements, the Mbéré travertine corresponds to chemico-lithoclastic/detrital limestone. In the Mbéré trough, numerous thermo-mineral springs are located along major fractures and faults. This result suggests that the Mbéré travertine deposit is related to the rising of deep water with the help of a fracturing system, similar to those of Irdi (Morocco), Italy and Turkey where there is much volcanism.

    The Sanaga Sud field, offshore Cameroon, is located just northwest of the coastal town of Kribi in the northern part of the Douala basin. The discovery well, Sanaga Sud A-1, was drilled in 1979 to test an apparent horst block that contained a prominent horizontal seismic amplitude. The Douala basin is one of a series of passive margin basins located along the coastline of central and southern Africa, and formed during the rifting of Africa and South America during the Early Cretaceous. Drilling results showed that the amplitude was a gas/water contact. Two appraisal wells, SSA-2 and SSA-3, were drilled in 1981. All three wells tested gas and condensate. Total recoverable hydrocarbons for the field are estimated to be approximately 1 tcf of gas. The trap in this field is composed of tilted and rotated fault blocks composed of interbedded Aptian to Albian sandstones, siltstones, and shales. The fault blocks were truncated by erosion (breakup unconformity) and later buried by a considerable thickness of onlapping Upper Cretaceous and Tertiary shale. The late Albian erosional unconformity forms the top of the trap over most of the field. Geochemical studies indicate a Lower Cretaceous source for the hydrocarbons. The gross pay thickness averages 250 m with an average porosity of 23% and an average permeability of 142 md. Reservoir lithologies range from well-sorted, massive sandstones to poorly sorted fine sandstones and siltstones containing shaly laminations that are carbonaceous and micaceous. The field is located predominantly in Block PH-38, but part of the field is in the Londji concession. Mobil Producing Cameroon, Inc., is the operator of PH-38 and Total Exploration and Production Cameroon is the operator of the Londji concession.

    Neonatal hyperbilirubinemia continues to be a leading cause of morbidity and mortality in resource-limited countries. The aim of this study was to measure the effectiveness of existing phototherapy units at a local hospital in Cameroon using an irradiance meter. Phototherapy units (n = 4) in one newborn nursery in Cameroon were evaluated. The average irradiance of the functioning units was 2.87 μW/cm(2)/nm, which is substantially below the recommended range of 10-30 μW/cm(2)/nm. With simple improvements, one new prototype unit was developed. Its irradiance was 23.3 μW/cm(2)/nm. We concluded that irradiance of phototherapy units should be measured, as many local nurseries worldwide may not be delivering effective treatment. Simple and cost-effective changes to phototherapy units can make a substantial improvement in irradiance. © The Author [2014]. Published by Oxford University Press. All rights reserved.

    Cameroon, a west-central African country with a ~ 20 million population, is commonly regarded as 'Africa in miniature' due to the extensive biological and cultural diversities of whole Africa being present in a single-country setting. This country is inhabited by ancestral human lineages in unique eco-climatic conditions and diverse topography. Over 90 percent Cameroonians are at risk of malaria infection, and ~ 41 percent have at least one episode of malaria each year. Historically, the rate of malaria infection in Cameroon has fluctuated over the years; the number of cases was about 2 million in 2010 and 2011. The Cameroonian malaria control programme faces an uphill task due to high prevalence of multidrug-resistant parasites and insecticide-resistant malaria vectors. Above all, continued human migration from the rural to urban areas as well as population exchange with adjoining countries, high rate of ecological instabilities caused by deforestation, poor housing, lack of proper sanitation and drainage system might have resulted in the recent increase in incidences of malaria and other vector-borne diseases in Cameroon. The available data on eco-environmental variability and intricate malaria epidemiology in Cameroon reflect the situation in the whole of Africa, and warrant the need for in-depth study by using modern surveillance tools for meaningful basic understanding of the malaria triangle (host-parasite-vector-environment).

    The Sinassi Batholith in the Central African Fold Belt (CAFB) of northern Cameroon represents the largest volume of plutonic rocks or granitoids massif of the Western Cameroonian Domain. It is made up dominantly of tonalite-trondhjemite-granodiorite (TTG) suite and lesser granite which are locally more or less deformed, and composed of varying proportions of quartz, plagioclase, K-feldspar, biotite, hornblende, sphene, magnetite, apatite and zircon. Major and trace element compositions of fifteen rock samples of granitoids (Djourdé granodiorite, Sinassi quartz diorite and orthogneisses groups) indicate that investigated rocks from the Sinassi Batholith are characterized by medium- to high-K calc-alkaline affinity and metaluminous I-type signature. In addition, their chondrite- and primitive mantle-normalized trace element patterns are strongly fractionated ((La/Yb)N = 2.96-61.40) and show respectively enrichment in LREE relative to HREE and enrichment in LILE compared to HFSE with moderate to slight negative Nb-Ta, Ti and Eu anomalies consistent with a continental magmatic arc setting related to a subduction zone. Geothermobarometric calculations using hornblende-plagioclase thermometry and aluminum-in-hornblende barometry on eleven rock samples indicate that plutons from Sinassi Batholith were emplaced at average temperatures and pressures ranging between 698 and 720 °C and 4.06-5.82 kbar (Djourdé granitoids), 698-728 °C and 4.04-5.34 kbar (Sinassi granitoids) and 667-670 and 4.23-4.76 kbar (orthogneisses group) respectively. The average emplacement depths estimates for the investigated granitoids is constrained at ca 16-18 km, indicating that at least 16 km of crustal rocks of the Sinassi Batholith must have been eroded or uplifted at approximately exhumation rates of 0.08-0.10 mm/year. Regardless of their Th/U ratios, geochronological results highlight three main events characterizing the Neoproterozoic tectonomagmatic evolution within the Sinassi Batholith

    Aim: The purpose of this study was to identify beliefs, perceptions and attitudes that may influence the return for test results after voluntary HIV testing in six district hospitals of the city of Douala in Cameroon.Methods: A qualitative study based on theory of planned behaviour (TPB) and using semi-structured interviews (N = 33) was conducted among individuals who underwent a voluntary HIV test in the prevention and voluntary testing and counselling centres (PVTCCs) located in six district hospitals of the city of Douala in Cameroon.Results: Participants identified a) seven advantages to return for their results (e.g., “knowing about my health condition,” “take the medication in the case of a positive result “and four disadvantages (e.g., fear of positive result); b) four groups of people that may influence their decision to return for HIV test results (e.g., family, friends/colleagues; c) one barrier (lack of time) and four factors that can facilitate return for the results after an HIV testing (e.g., the career project).Conclusion: The results of this study indicate that individuals who voluntarily undergo an HIV test in PVTCCs of the Douala district hospitals in Cameroon perceived real advantages and very few disadvantages and barriers to know their HIV status. Particular attention should be given to organizational factors that may be responsible for failure to return for HIV test results and post-test counselling.

    Background. Malaria remains a major killer of children in Sub-Saharan Africa, while anaemia is a public health problem with significant morbidity and mortality. Examining the factors associated with moderate to severe anaemia (MdSA) and malarial anaemia as well as the haematological characteristics is essential. Methodology. Children (1-14 years) at presentation at the Regional Hospital Annex-Buea were examined clinically and blood samples were collected for malaria parasite detection and full blood count evaluation. Results. Plasmodium falciparum, anaemia, and malarial anaemia occurred in 33.8%, 62.0%, and 23.6% of the 216 children, respectively. Anaemia prevalence was significantly higher in malaria parasite positive children and those with fever than their respective counterparts. MdSA and moderate to severe malarial anaemia (MdSMA) were detected in 38.0% and 15.3% of the participants, respectively. The prevalence of MdSA was significantly higher in children whose household head had no formal education, resided in the lowland, or was febrile, while MdSMA was significantly higher in febrile children only. Children with MdSMA had significantly lower mean white blood cell, lymphocyte, and platelet counts while the mean granulocyte count was significantly higher. Conclusion. Being febrile was the only predictor of both MdSA and MdSMA. More haematological insult occurred in children with MdSMA compared to MdSA.

    In 2011, Thailand was affected by the one of the worst flood disasters in recent times. Hospitals in Thailand were faced with the challenge of managing the health impacts from this natural disaster. The purpose of this study was to assess flood disaster preparedness among hospitals in the central region of Thailand. A survey questionnaire was given to twenty-seven key people responsible for hospital disaster preparedness that experienced disruptions to health services (severely, moderately and slightly) during the flood disaster in 2011 in the central region of Thailand. Of the twenty-four participating hospitals, not one had satisfied the standards in all the dimensions of flood disaster preparedness. All respondent hospitals were deficiently prepared with regard to surge capacity, the management of healthcare services and the management of the supporting systems. The availability of supplies and equipment were found to be in place but preparations were found to be inadequate in organizing staff at all participating hospitals. Trained staff members regarding disaster response were reported to be present in all respondent hospitals. Hospitals that experienced slightly disruptions to their health services did not elect to do any exercises to meet the set standards. None of the hospitals that experienced slightly disruptions to their health services performed any evaluation and improvement in terms of disaster preparedness. Many hospitals were not up to standard in terms of disaster preparedness. Hospitals should prioritize disaster preparedness to fulfill their responsibility during crisis situations and improve their flood disaster preparedness.

    The aim of the study was to investigate the pattern of valvular lesions, the mortality and the challenges in five years follow-up in children with post-rheumatic valvulopathies in natural history in St. Elizabeth Catholic General hospital Shisong, cardiac centre. This retrospective analysis included 270 patients aged between 5 and 16 years old suffering from post-rheumatic valvulopathies who consulted in the cardiac centre from July 2008 through July 2013. Postrheumatic valvulopathies were diagnosed according to the World heart federation criteria. Data from patients' records, two-dimensional echocardiographic studies, and electrocardiograms were reviewed. Patients and their family were contacted every six months. The duration of the follow-up was 60months. Patients aged between 5 and 16 years old with a mean age of 12.4±4.5 years. Female gender was representing 63% (n=170) of the population. Surgery was indicated in 256 cases. Lesions of the valves needing prophylaxis with penicillin was diagnosed in 14 cases. In 95 patients surgical correction could not be performed. Mitral regurgitation was the commonest echocardiographic diagnosis present in 61.5%, n=164 patients; 38.5%, n=103 patients had aortic regurgitation. Mitral stenosis and mitral disease were also represented in 6%, n=16, and 8%, n= 21 patients respectively. Pulmonary hypertension was the common echocardiographic complication of the disease in=234, 87% of cases. Clinically, complications of the disease included congestive heart failure (n=229, 85%), growth retardation (n=162, 60%), sudden death (n=27, 10%). On presentation, n=210, 78% of cases were admitted. Mortality in two years was 35%, (p≤0.05, 95% CI=2.5-6.5), in five years was 65% (p≤ 0.05, 93% CI= 2.7-7.21). The challenges faced are patients' negligence and poor discipline, wrong beliefs, poverty. Post-rheumatic mitral valve regurgitation is the pathology the most encountered. Pulmonary hypertension is the most common echocardiographic

    Simian virus infections of humans are an increasing public health concern. Simian foamy virus (SFV) infections have been reported in persons occupationally exposed to nonhuman primates and in a few hunters in Cameroon. To better understand this retroviral zoonosis in natural settings, we studied persons who lived in southern Cameroon, near nonhuman primate habitats. First we studied a general population of 1,164 adults; 4 were SFV positive according to serologic and molecular assays. Then we studied 85 persons who reported having been bitten or scratched by nonhuman primates; 7/29 (24.1%) of those who had contact with apes (gorillas or chimpanzees) were SFV positive, compared with only 2/56 (3.6%) of those who had had contact with monkeys. These data demonstrate efficient transmission of SFVs to humans in natural settings in central Africa, specifically following ape bites, and viral persistence in the human host. PMID:18252101

  20. Two-tier charging in Maputo Central Hospital: Costs, revenues and effects on equity of access to hospital services

    PubMed Central

    2011-01-01

    Background Special services within public hospitals are becoming increasingly common in low and middle income countries with the stated objective of providing higher comfort services to affluent customers and generating resources for under funded hospitals. In the present study expenditures, outputs and costs are analysed for the Maputo Central Hospital and its Special Clinic with the objective of identifying net resource flows between a system operating two-tier charging, and, ultimately, understanding whether public hospitals can somehow benefit from running Special Clinic operations. Methods A combination of step-down and bottom-up costing strategies were used to calculate recurrent as well as capital expenses, apportion them to identified cost centres and link costs to selected output measures. Results The results show that cost differences between main hospital and clinic are marked and significant, with the Special Clinic's cost per patient and cost per outpatient visit respectively over four times and over thirteen times their equivalent in the main hospital. Discussion While the main hospital cost structure appeared in line with those from similar studies, salary expenditures were found to drive costs in the Special Clinic (73% of total), where capital and drug costs were surprisingly low (2 and 4% respectively). We attributed low capital and drug costs to underestimation by our study owing to difficulties in attributing the use of shared resources and to the Special Clinic's outsourcing policy. The large staff expenditure would be explained by higher physician time commitment, economic rents and subsidies to hospital staff. On the whole it was observed that: (a) the flow of capital and human resources was not fully captured by the financial systems in place and stayed largely unaccounted for; (b) because of the little consideration given to capital costs, the main hospital is more likely to be subsidising its Special Clinic operations, rather than the

    The treatment of emergencies in a hospital should be organized in a central interdisciplinary emergency department (ER). It is the main entrance for all patients with acute illness or injuries. There are multiple advantages of such a central unit. Quality of treatment and economic efficiency is improved. The interdisciplinary diagnostics and treatment at one place prevents time-consuming and unnecessary transport. The fact that more complex diseases and injuries need specialized doctors in specific disciplines should be considered in personnel planning of the ER. To reinsure that the entire medical staff of the hospital is familiar with the daily routine and clinical pathways of the ER, doctors from other departments of the hospital should always be part of the ER team.

    The study aims to identify key enablers fostering clinical risk management (CRM) in hospitals to guide health care in this vital area of patient safety. A cross-sectional survey was conducted at the national level in 324 Swiss hospitals in 2007-2008 to assess the relationship between key elements and systematic CRM. Therefore, a comprehensive monitoring instrument for CRM was used for the first time. Organizational factors (e.g. strategy, coordination, resources) and structural conditions (e.g. hospital size) were tested as key elements. CRM was assessed by evaluating its maturity (i.e. the level of CRM development) by 12 theoretically derived indices joining together essential aspects of CRM at the hospital level and the service level. Chi-square measures were used to analyse the relationships between organizational factors or structural conditions and maturity of CRM. Participation in this voluntary survey was good, with CRM experts of 138 out of 324 hospitals responding (response rate 43%). Three key enablers for CRM were identified: implementing a function for central CRM coordination, assuring dialogue with and between the different hospital services, and developing strategic CRM objectives. This study offers, for the first time, an assessment of the maturity of hospitals' CRM and identifies key enablers related to CRM. This is a feasible first step in guiding hospitals to shape their CRM and presents a basis for future studies, for example, linking CRM to outcome data. © 2012 Blackwell Publishing Ltd.

    Central line-associated bloodstream infection (CLABSI) is the major complication of central venous catheters (CVC). The aim of the study was to test the effectiveness of a hospital-wide strategy on CLABSI reduction. Between 2008 and 2011, all CVCs were observed individually and hospital-wide at a large university-affiliated, tertiary care hospital. CVC insertion training started from the 3rd quarter and a total of 146 physicians employed or newly entering the hospital were trained in simulator workshops. CVC care started from quarter 7 and a total of 1274 nurses were trained by their supervisors using a web-based, modular, e-learning programme. The study included 3952 patients with 6353 CVCs accumulating 61,366 catheter-days. Hospital-wide, 106 patients had 114 CLABSIs with a cumulative incidence of 1.79 infections per 100 catheters. We observed a significant quarterly reduction of the incidence density (incidence rate ratios [95% confidence interval]: 0.92 [0.88-0.96]; P<0.001) after adjusting for multiple confounders. The incidence densities (n/1000 catheter-days) in the first and last study year were 2.3/1000 and 0.7/1000 hospital-wide, 1.7/1000 and 0.4/1000 in the intensive care units, and 2.7/1000 and 0.9/1000 in non-intensive care settings, respectively. Median time-to-infection was 15 days (Interquartile range, 8-22). Our findings suggest that clinically relevant reduction of hospital-wide CLABSI was reached with a comprehensive, multidisciplinary and multimodal quality improvement programme including aspects of behavioural change and key principles of good implementation practice. This is one of the first multimodal, multidisciplinary, hospital-wide training strategies successfully reducing CLABSI.

    Background Despite nation-wide efforts to reduce health care costs through hospital closures and centralization of services, little is known about the impact of such actions. We conducted this study to determine the effect of a hospital closure in Calgary and the resultant centralization of coronary revascularization procedures from 2 facilities to a single location. Methods Administrative data were used to identify patients who underwent coronary artery bypass grafting (CABG), including those who had combined CABG and valve procedures, and patients who underwent percutaneous transluminal angioplasty (PTCA) in the Calgary Regional Health Authority from July 1994 to March 1998. This period represents the 21 months preceding and the 24 months following the March 1996 hospital closure. Measures, including mean number of discharges, length of hospital stay, burden of comorbidity and in-hospital death rates, were compared before and after the hospital closure for CABG and PTCA patients. Multivariate analyses were used to derive risk-adjustment models to control for sociodemographic variables and comorbidity. Results The number of patients undergoing CABG was higher in the year following than in the year preceding the hospital closure (51.6 per 100 000 before v. 67.3 per 100 000 after the closure); the same was true for the number of patients undergoing PTCA (129.8 v. 143.6 per 100 000). The burden of comorbidity was significantly higher after than before the closure, both for CABG patients (comorbidity index 1.3 before v. 1.5 after closure, p < 0.001) and for PTCA patients (comorbidity index 1.0 before v. 1.1 after, p = 0.04). After adjustment for comorbidity, the mean length of hospital stay was significantly lower after than before the closure for CABG patients (by 1.3 days) and for PTCA patients (by 1.0 days). The adjusted rates of death were slightly lower after than before the closure in the CABG group. The adjusted rates of death or CABG in the PTCA group did not

    2013-01-01

    Background Central venous catheter-associated bloodstream infections in children are an increasingly recognized serious safety problem worldwide, but are often preventable. Central venous catheter bundles have proved effective to prevent such infections. Successful implementation requires changes in the hospital system as well as in healthcare professionals’ behaviour. The aim of the study is to evaluate process and outcome of implementation of a state-of-the-art central venous catheter insertion and maintenance bundle in a large university children’s hospital. Methods/design An interrupted time series design will be used; the study will encompass all children who need a central venous catheter. New state-of-the-art central venous catheter bundles will be developed. The Pronovost-model will guide the implementation process. We developed a tailored multifaceted implementation strategy consisting of reminders, feedback, management support, local opinion leaders, and education. Primary outcome measure is the number of catheter-associated infections per 1000 line-days. The process outcome is degree of adherence to use of these central venous catheter bundles is the secondary outcome. A cost-effectiveness analysis is part of the study. Outcomes will be monitored during three periods: baseline, pre-intervention, and post-intervention for over 48 months. Discussion This model-based implementation strategy will reveal the challenges of implementing a hospital-wide safety program. This work will add to the body of knowledge in the field of implementation. We postulate that healthcare workers’ willingness to shift from providing habitual care to state-of-the-art care may reflect the need for consistent care improvement.

    The study aimed to analyze the history of the use of the peripherally inserted central catheters in adult patients admitted to hospital from 2000 to 2007. The historical cohort approach was used with retrospective data collection from medical records of the Catheter Group of the Moinhos de Vento Hospital Association in Porto Alegre, RS, totaling 229 catheters inserted. The growth curve in the use of the PICC was from 1 catheter inserted in 2000 to 57 in 2007. The most prevalent pathology was oncology (17.9%, n=41). In relation to the indications of use, antibiotic use prevailed (54.1%, n=124). In the radiological confirmation the vena cava was prevalent (68.1%, n=156). The use of the PICC in the hospital environment is expanding and nursing has a fundamental role in its insertion, maintenance and removal.

    For many years peroperative cholangiography has been routinely used for bile duct surgery in the Western countries. However recent publications showing high rate of inconclusive peroperative cholangiography (47%) has cast doubt on this attitude. Surgeons in Africa and particularly in Cameroon have already replaced peroperative cholangiography with other indicators such as clinical history and preoperative echography, anticipating cholangitis. For some indications, e.g. Mirizzi syndrome, peroperative cholangiography is essential for surgery. The fluoroscopes required for this exploration should be made available in our hospitals since they are also needed for traumatology, vascular surgery, and other specialities. In addition this syndrome may be more common in our region.

    Use of users' perception in measuring quality of care has been shown to be useful in screening problems and in planning for improvement of quality of health care delivery. Traditionally, quality of care has been measured using professional standards, neglecting users' opinions which may leave psychosocial needs unattended. The objective of this descriptive cross-sectional study was to assess users' perceptions of quality of care given at outpatient department (OPD) at Kilosa District Hospital in Central Tanzania. Hospital based exit interviews were conducted to adult patients or caregivers of children attending the hospital. Focus Group Discussions were conducted among community members in selected villages within the hospital catchment area. Information on perceptions on care provider-patient interaction, cost of service, availability of medicines, equipment and health personnel was sought from the participants. Overall OPD was perceived to have several shortcomings including verbal abuse of patients by care providers, lack of responsiveness to patients' needs, delays, inadequate examination, unreliable supply of medicines, lack of confidentiality and favouritism in health care provision. Cost of service was perceived to be reasonable provided medicines were available. In conclusion, provider-patient interactions, timely services, supply of medicines and favouritism were the major factors affecting quality of service at the hospital. Efforts should be made to address the shortcomings so as to improve quality of care and users perceptions.

Offers were received for eight permits in Douala Basin and Kribi-Campo basin from Exxon, Petrofina and Phillips Petroleum. Nine blocks were offshore and four were onshore. No offers were made for blocks in Douala Basin. Exxon is seeking offshore permits close to the Chad border in the north. Petrofina and Phillips jointly put in bids for three permits in Rio del Rey offshore basin close to the Niger River delta and the Nigerian border where Elf/Pecten hold permits.

    Evidence of short-term effects of ultrafine particles (UFP) on health is still inconsistent and few multicenter studies have been conducted so far especially in Europe. Within the UFIREG project, we investigated the short-term effects of UFP and fine particulate matter (particulate matter with an aerodynamic diameter less than 2.5 μm [PM2.5]) on daily cause-specific hospital admissions in five Central and Eastern European cities using harmonized protocols for measurements and analyses. Daily counts of cause-specific hospital admissions focusing on cardiovascular and respiratory diseases were obtained for Augsburg and Dresden (Germany), 2011-2012; Chernivtsi (Ukraine), 2013 to March 2014; and Ljubljana (Slovenia) and Prague (Czech Republic), 2012-2013. Air pollution and meteorologic data were measured at fixed monitoring sites in all cities. We analyzed city-specific associations using confounder-adjusted Poisson regression models and pooled the city-specific effect estimates using metaanalysis methods. A 2,750 particles/cm(3) increase (average interquartile range across all cities) in the 6-day average of UFP indicated a delayed and prolonged increase in the pooled relative risk of respiratory hospital admissions (3.4% [95% confidence interval, -1.7 to 8.8%]). We also found increases in the pooled relative risk of cardiovascular (exposure average of lag 2-5, 1.8% [0.1-3.4%]) and respiratory (6-d average exposure, 7.5% [4.9-10.2%]) admissions per 12.4 μg/m(3) increase (average interquartile range) in PM2.5. Our findings indicated delayed and prolonged effects of UFP exposure on respiratory hospital admissions in Central and Eastern Europe. Cardiovascular and respiratory hospital admissions increased in association with an increase in PM2.5. Further multicenter studies are needed using harmonized UFP measurements to draw definite conclusions on health effects of UFP.

    Developing a patient safety culture was one of the recommendations made by the Institute of Medicine (IOM) to assist hospitals in improving patient safety. Nurses are the key to safety improvements in hospitals. It is necessary to know their awareness and perception regarding institutional safety climate. The aim of this study is to explore perceptions of patient safety among nursing staff in a tertiary hospital in Central Saudi Arabia in different discipline units. The current study was conducted at Prince Sultan Military Medical City (PSMMC), a tertiary center in Riyadh, Central Saudi Arabia. In November 2014, five hundred nurses were randomly selected to participate in this study. A survey questionnaire with Likert scale was adopted covering characteristics of participants together with their views on patient safety issues. Two hundred and twenty-four participants filled the questionnaire with a response rate of 44.8%. The overall perception of patient safety among participants was (57.9%). The majority (74.1%) thought that the existing system is good at preventing errors and only one third indicated that they have patient safety problems. Most of the participants were happy with the existing patient safety culture including organizational learning/continuous improvement (95.5%), and errors feedback and communication (76.64%). In conclusion, this study showed that perception of patient safety was sub-optimal among nurses and there are several areas for improvement regarding safety culture.

    Limited data on the risk of peripherally inserted central venous catheter-associated bloodstream infections (PICC BSIs) in hospitalized patients are available. In 2007, dedicated intravenous therapy nurses were no longer available to place difficult peripheral intravenous catheters or provide PICC care Barnes-Jewish Hospital. To determine the hospital-wide incidence of PICC BSIs and to assess the effect of discontinuing intravenous therapy service on PICC use and PICC BSI rates. A 1,252-bed tertiary care teaching hospital. A 31-month retrospective cohort study was performed. PICC BSIs were defined using National Healthcare Safety Network criteria. In total, 163 PICC BSIs were identified (3.13 BSIs per 1,000 catheter-days). PICC use was higher in intensive care units (ICUs) than non-ICU areas (PICC utilization ratio, 0.109 vs 0.059 catheter-days per patient-day for ICU vs non-ICU; rate ratio [RR], 1.84 [95% confidence interval {CI}, 1.78-1.91]). PICC BSI rates were higher in ICUs (4.79 vs 2.79 episodes per 1,000 catheter-days; RR, 1.7 [95% CI, 1.10-2.61]). PICC use increased hospital-wide after the intravenous therapy service was discontinued (0.049 vs 0.097 catheter-days per patient-day; P =.01), but PICC BSI rates did not change (2.68 vs 3.63 episodes per 1,000 catheter-days; P =.06). Of PICC BSIs, 73% occurred in non-ICU patients. PICC use and PICC BSI rates were higher in ICUs; however, most of the PICC BSIs occurred in non-ICU areas. Reduction in intravenous therapy services was associated with increased PICC use across the hospital, but PICC BSI rates did not increase.

    AIM To complete the data of ocular trauma in central China, as a well-known tertiary referral center for ocular trauma, we documented the epidemiological characteristics and visual outcomes of patients hospitalized for ocular trauma in this region. METHODS A retrospective study of patients hospitalized for ocular trauma in central China from 2006 to 2011 was performed. RESULTS This study included 5964 eyes of 5799 patients. The average age was 35.5±21.8y with a male-to-female ratio of 2.8:1. The most common age was 45-59y age group. Most patients were farmers and workers (51.9%). The most common injuries were firework related (24.5%), road traffic related (24.2%), and work related (15.0%). Among the most common causative agents were firecrackers (24.5%), followed by metal/knife/scissors (21.4%). Most injuries occurred in January (14.2%), February (27.0%), and August (10.0%). There were 8.5% patients with ocular injuries combined with other injuries. The incidence of open ocular injuries (4585 eyes, 76.9%) was higher than closed ocular injuries (939 eyes, 15.7%). The incidences of chemical and thermal ocular injuries were 1.2% and 0.6%. Ocular trauma score (OTS) predicted final visual acuity at non light perception (NLP), 20/200-20/50 and 20/40 with a sensitivity of 100%, and light perception (LP)/hand motion (HM) and 1/200-19/200 with a specificity of 100%. CONCLUSIONS This study provides recent epidemiological data of patients hospitalized for ocular trauma in central China. Some factors influencing the visual outcome include time interval between injury and visit to the clinic, wound location, open or closed globe injury, initial visual acuity, and OTS. PMID:25709927

    Rational nutritional support shall be based on nutritional screening and nutritional assessment. This study is aimed to explore nutritional risk screening and its influencing factors of hospitalized patients in central urban area. It is helpful for the early detection of problems in nutritional supports, nutrition management and the implementation of intervention measures, which will contribute a lot to improving the patient's poor clinical outcome. A total of three tertiary medical institutions were enrolled in this study. From October 2015 to June 2016, 1202 hospitalized patients aged ≥18 years were enrolled in Nutrition Risk Screening 2002 (NRS2002) for nutritional risk screening, including 8 cases who refused to participate, 5 cases of same-day surgery and 5 cases of coma. A single-factor chi-square test was performed on 312 patients with nutritional risk and 872 hospitalized patients without nutritional risk. Logistic regression analysis was performed with univariate analysis (P<0.05), to investigate the incidence of nutritional risk and influencing factors. The incidence of nutritional risk was 26.35% in the inpatients, 25.90% in male and 26.84% in female, respectively. The single-factor analysis showed that the age ≥60, sleeping disorder, fasting, intraoperative bleeding, the surgery in recent month, digestive diseases, metabolic diseases and endocrine system diseases had significant effects on nutritional risk (P<0.05). Having considered the above-mentioned factors as independent variables and nutritional risk (Y=1, N=0) as dependent variable, logistic regression analysis revealed that the age ≥60, fasting, sleeping disorders, the surgery in recent month and digestive diseases are hazardous factors for nutritional risk. Nutritional risk exists in hospitalized patients in central urban areas. Nutritional risk screening should be conducted for inpatients. Nutritional intervention programs should be formulated in consideration of those influencing

    After four decades of a repressive dictatorial regime during which homosexuality was banned and punished with prison sentence and electroshock, Spain became a democratic country in 1978. The social, political, and legal debates previous to the passing of the law on same-sex marriage in June 2005 fueled lesbian visibility in the media. Considering that the emergence of lesbian representation has been linked to these social and political changes, our contribution centers on the ways in which the prime time TV series Hospital Central unravels as a vehicle for the normalization of lesbian relationships and families as addressed to a mostly heterosexual audience.

    The central-line associated bloodstream infections (CLABSI) are the most common healthcare-associated infections in childhood. Despite the international data available on healthcare-associated infections in selected groups of patients, there is a lack of large and good quality studies. The present survey is the first prospective study monitoring for 6 months the occurrence of central-line associated bloodstream infections in all departments of an Italian tertiary care children's university hospital. The study involved all children aged less than 18 years admitted to Meyer Children's University Hospital, Florence, Italy who had a central line access between the October 15(th), 2014 and the April 14(th), 2015. CLABSI were defined according to the Center for Disease Control and Prevention criteria. CLABSI incidence rates with 95% confidence limits were calculated and stratified for the study variables. For each factor the relative risk and 95% confidence intervals were evaluated. Statistical analysis was performed using the statistical software SPSS for Windows, version 22.0 (SPSS Inc., Chicago, IL), p < 0.05 was considered statistically significant. CLABSI rate was 3.73/1000 (95% CI: 2.54-5.28) central line-days. A higher CLABSI incidence was seen with female gender (p = 0.045) and underlying medical conditions (excepting prematurity, surgical diseases and malignancy) (p = 0.06). In our study 5 infections, were caused by extended-spectrum β-lactamase producing organisms and in one case by carbapenem-resistant Klebsiella pneumoniae. Our study confirms the spreading of multi-resistant pathogens as causes of healthcare associated infections in children. An increased incidence rate of CLABSI in our study was related to underlying medical conditions. Pediatric studies focusing on healthcare infections in this type of patients should be done in order to deepen our understanding on associated risk factors and possible intervention areas.

    The overall situation in Guatemala, Central America, regarding programs caring for women's reproductive health has been lagging behind for some decades. Since the year 2000, 56% of Guatemalan families have lived below the poverty line. Guatemala has one of the highest fertility rates (lifetime births per woman) in Latin America and the Caribbean countries, comparable to those observed in less developed countries in Africa. Considering the lack of sex education, poor access to effective contraceptive methods and issues of unwanted pregnancy, Guatemalan women engage in illegal and unsafe abortions, which often causes harm and sometimes death. A key strategy designed to improve women's health is through free and informed access to contraceptive methods that are effective and accepted by Guatemalan women. From July 1, 2003, to December 31, 2006, specially hired trained facilitators visited 22 public hospitals for 1 week to train corresponding physician staff in postabortion counseling, enabling them to assist patients to select and use an effective contraceptive method. To monitor the progress achieved, the trained facilitators returned 4 weeks later. The main purpose of the training was to focus in strengthening the understanding and technical capacity of the hospital staff to implement postabortion contraceptive counseling and to enable women to obtain an effective contraceptive method prior to hospital discharge. Out of 22 hospitals, 21 managed to improve their record for counseling patients admitted for postabortion complications, from 31% to 96%. Furthermore, the percentage of women being discharged from the hospital with an effective contraceptive method rose from 20% to 64% from 2003 to 2006. The successful results obtained during this study to meet postabortion demands by Guatemalan women point out to the urgent need for the government to expand this initiative within the national health system, including health centers nationwide. This is one of the worldwide

    Compliance with minimum volume standards for specific procedures serves as a criterion for high-quality patient care. International experiences report a centralization of the respective procedures. In Germany, minimum volume standards for hospitals were introduced in 2004 for 5 procedures (complex esophageal and pancreatic interventions; liver, kidney and stem cell transplantations), in 2006 total knee replacement was added. This study explores whether any centralization is discernible for these procedures in Germany. A retrospective longitudinal analysis of secondary data serves to determine a possible centralization of procedures from the system perspective. Centralization means that over time, fewer hospitals perform the respective procedure, the case volume in high-volume hospitals increases together with their percentage of the annual total case volume, and the case volume in low-volume hospitals decreases together with their percentage of the annual total case volume. Using data from the mandatory hospital quality reports for the years 2006, 2008 and 2010 we performed Kruskal Wallis and chi-square tests to evaluate potential centralization effects. No centralization was found for any of the six types of interventions over the period from 2006 to 2010. The annual case volume and the number of hospitals performing interventions rose at differing rates over the 5-year period depending on the type of intervention. Seven percent of esophagectomies and 14% of pancreatectomies are still performed in hospitals with less than 10 interventions per year. For the purpose of further centralization of interventions it will be necessary to first analyze and then appropriately address the reasons for non-compliance from the hospital and patient perspective.

  6. A Ground Deformation Monitoring Approach to Understanding Magma Chamber Systems and Eruptive Cycles of Mount Cameroon

    Mount Cameroon is a 13,400ft basanite volcano on the passive margin of West Africa. It has erupted seven times in the past century making it one of the most active volcanoes in Africa. Most recently Mount Cameroon erupted in 1999 and 2000 first issuing strombolian explosions from vents near the summit, and later erupting effusively from a fissure running southwest from the summit (Suh et al., 2003). Prior to 2004, the only monitoring equipment on Mount Cameroon was a small seismometer network installed following the 1982 eruption. By 1999 only a single seismometer in the network was functional. Seismic activity did not rise above background levels until the few days immediately preceding the eruption. In an effort to raise awareness of the volcano's condition and provide a more efficient warning of impending eruptions we have begun constructing a ground deformation network on Mount Cameroon. The new network currently consists of two Applied Geomechanics 711-2A(4X) biaxial tiltmeters capable of resolving 0.1 microradians of tilt. One station is located approximately 500 m from the 2000 summit vent, and the other is approximately 1km away from the central fissure approximately 5km southwest of the 2000 summit vent. Three primary processes could precede eruptions at Mt. Cameroon, offering the opportunity for detection and prediction by our network. These processes are magma chamber pressurization, magma ascent via a central conduit, and/or propagation of magma along the central fissure. Magma chamber location, if a significant chamber exists, is poorly constrained, however, previous petrologic studies on Mount Cameroon (Suh et al., 2003; Fitton et al., 1983) suggest Mount Cameroon magmas originate at a depth less than 40km. Published seismic data (Ambeh, 1989) contains evidence of magmatic activity and possible chambers at depths ranging from 10km to 70km. Preliminary calculations using a simple Mogi model suggest deformation caused by pressurization of a large

    Little is known on the magnitude and correlates of insulin resistance in HIV-infected people in Africa. We determined the prevalence of insulin resistance and investigated associated factors in HIV-infected adult Cameroonians. We conducted a cross-sectional study at the Yaoundé Central Hospital, Cameroon; during which we enrolled HIV-infected people aged 30 to 74 years with no previous history of cardiovascular disease. An homeostatic model assessment of insulin resistance (HOMA-IR) like index served to assess insulin sensitivity with insulin resistance defined by values of 2.1 or higher. We included 452 patients (20% men). Their mean age was 44.4 ± 9.8 years and 88.5% of them were on antiretroviral therapy (93.3% on first line regimen including Zidovudine, lamivudine and Efavirenz/Nevirapine). Of all participants, 28.5% were overweight, 19.5% had obesity and 2.0% had diabetes. The prevalence of insulin resistance was 47.3% without any difference between patients on ART and those ART-naïve (48.5% vs. 38.5%; p = 0.480). Obesity was the only factor independently associated with insulin resistance (adjusted odds ratio: 2.28; 95% confidence interval: 1.10-4.72). Insulin resistance is present in nearly half of HIV-infected patients in Cameroon despite a low prevalence rate of diabetes, and is associated with obesity.

    Cancer is a major disease burden worldwide resulting in high morbidity and mortality. It is the leading cause of mortality in developed countries and is one of the three leading causes of death for adults in developing countries. Pathological examination of tissue biopsies with histological confirmation of a correct cancer diagnosis is central to cancer care. Without an accurate and specific pathologic diagnosis, effective treatment cannot be planned or delivered. In addition, there are marked geographical variations in incidence of cancer overall, and of the specific cancers seen. Much of the published literature on cancer incidence in developing countries reflects gross estimates and may not reflect reality. Performing baseline studies to understand these distributions lays the groundwork for further research in this area of cancer epidemiology. Our current study surveys and ranks cancer diagnoses by individual anatomical site at Queen Elizabeth Central Hospital (QECH) which is the largest teaching and referral hospital in Malawi. A retrospective study was conducted reviewing available pathology reports over a period of one full year from January 2010 to December 2010 for biopsies from patients suspected clinically of having cancer. There were 544 biopsies of suspected cancer, taken from 96 anatomical sites. The oesophagus was the most common biopsied site followed by breast, bladder, bone, prostate, bowel, and cervical lymph node. Malignancies were found in biopsies of the oesophagus biopsies (squamous cell carcinoma, 65.1%; adenocarcinoma, 11.6%), breast (57.5%), bladder (squamous cell carcinoma, 53.1%) and stomach (37.6%). Our study demonstrates that the yield of biopsy for clinically suspected malignancy was greater than 50% for the 11 most common sites and provides a current survey of cancer types by site present in the population reporting to our hospital.

    Introduction Infectious diseases are one of the major causes of child mortality in India. Pediatric patients are commonly prescribed antibiotics for non-bacterial infections. Monitoring of local antibiotic prescribing with respect to the diagnosis is necessary to improve the prescribing practices. The aim of the study was to describe antibiotic prescribing for potential infections among patients admitted in pediatric departments in two private sector hospitals; one teaching (TH) and one non-teaching (NTH) in Central India. Methods Data from all patients admitted at the pediatric departments of both study hospitals was collected manually, for 3 years (2008–2011) using a customized form. Data from inpatients aged 0–18 years, diagnosed with; acute gastroenteritis (AGE), respiratory tract infections, enteric fever, viral fever or unspecified fever were focused for analysis. Antibiotic prescriptions were analysed using the WHO Anatomical Therapeutic Chemical (ATC) classification system and defined daily doses (DDDs). Adherence to the Indian Academy of Pediatrics list of essential medicines (IAP-LEM) was investigated. P-values <0.05 were considered significant. Results Oftotal6, 825 inpatients admitted at two pediatric departments, 510 patients from the TH and 2,479from the NTH were selected based on the assigned potential infectious diagnoses. Of these, 224 patients (44%) at the TH and 2,088 (84%) at the NTH were prescribed at least one antibiotic during hospital stay (odds ratio-0.69, 95%confidence interval-0.52 to 0.93; p<0.001). Patients with AGE, viral- and enteric fever were frequently prescribed antibiotics at both hospitals, yet higher proportion were prescribed antibiotics at the NTH compared to the TH. Broad-spectrum antibiotics were the most commonly prescribed antibiotic class in both hospitals, namely third generation cephalosporins, J01DD (69%) at the TH, and new fixed dose combinations of antibiotics J01R (FDCs, 42%) at the NTH. At the TH, 37% of the

    The Nigeria-Cameroon chimpanzee (Pan troglodytes ellioti) is found in the Gulf of Guinea biodiversity hotspot located in western equatorial Africa. This subspecies is threatened by habitat fragmentation due to logging and agricultural development, hunting for the bushmeat trade, and possibly climate change. Although P. t. ellioti appears to be geographically separated from the neighboring central chimpanzee (P. t. troglodytes) by the Sanaga River, recent population genetics studies of chimpanzees from across this region suggest that additional factors may also be important in their separation. The main aims of this study were: 1) to model the distribution of suitable habitat for P. t. ellioti across Cameroon and Nigeria, and P. t. troglodytes in southern Cameroon, 2) to determine which environmental factors best predict their optimal habitats, and 3) to compare modeled niches and test for their levels of divergence from one another. A final aim of this study was to examine the ways that climate change might impact suitable chimpanzee habitat across the region under various scenarios. Ecological niche models (ENMs) were created using the software package Maxent for the three populations of chimpanzees that have been inferred to exist in Cameroon and eastern Nigeria: (i) P. t. troglodytes in southern Cameroon, (ii) P. t. ellioti in northwestern Cameroon, and (iii) P. t. ellioti in central Cameroon. ENMs for each population were compared using the niche comparison test in ENMtools, which revealed complete niche divergence with very little geographic overlap of suitable habitat between populations. These findings suggest that a positive relationship may exist between environmental variation and the partitioning of genetic variation found in chimpanzees across this region. ENMs for each population were also projected under three different climate change scenarios for years 2020, 2050, and 2080. Suitable habitat of P. t. ellioti in northwest Cameroon / eastern Nigeria is

    Chimpanzees (Pan troglodytes) can be divided into four subspecies. Substantial phylogenetic evidence suggests that these subspecies can be grouped into two distinct lineages: a western African group that includes P. t. verus and P. t. ellioti and a central/eastern African group that includes P. t. troglodytes and P. t. schweinfurthii. The geographic division of these two lineages occurs in Cameroon, where the rages of P. t. ellioti and P. t. troglodytes appear to converge at the Sanaga River. Remarkably, few population genetic studies have included wild chimpanzees from this region. We analyzed microsatellite genotypes of 187 wild, unrelated chimpanzees, and mitochondrial control region sequencing data from 604 chimpanzees. We found that chimpanzees in Cameroon and eastern Nigeria comprise at least two, and likely three populations. Both the mtDNA and microsatellite data suggest that there is a primary separation of P. t. troglodytes in southern Cameroon from P. t. ellioti north and west of the Sanaga River. These two populations split ~200-250 thousand years ago (kya), but have exchanged one migrant per generation since separating. In addition, P. t. ellioti consists of two populations that split from one another ~4 kya. One population is located in the rainforests of western Cameroon and eastern Nigeria, whereas the second population appears to be confined to a savannah-woodland mosaic in central Cameroon. Our findings suggest that there are as many as three genetically distinct populations of chimpanzees in Cameroon and eastern Nigeria. P. t. troglodytes in southern Cameroon comprises one population that is separated from two populations of P. t. ellioti in western and central Cameroon, respectively. P. t. ellioti and P. t. troglodytes appear to be characterized by a pattern of isolation-with-migration, and thus, we propose that neutral processes alone can not explain the differentiation of P. t. ellioti and P. t. troglodytes.

    The aim of this investigation was to describe the effects of standardization and central control of the processes involved in postoperative pain management from patient and employee perspectives. Patients (n = 282/307) and respective hospital staff (n = 149/119) evaluated the processes, the quality of postoperative pain management and result parameters 3 months before and 12 months after the introduction of standardization of the postoperative pain therapy process using a set of standardized questionnaires. Pain level and the waiting period for an analgesic partially decreased and a higher subjective effectiveness of medication was achieved in patients after the standardization. Patients felt that the pain was taken more seriously and contacted the staff for additional medication more frequently. From an employee viewpoint the quality of care and individual competence and ability to treat pain increased after the introduction of standardization. Pain assessment was improved and employees rated their knowledge and education level as higher than before the intervention. Patients with pre-existing chronic pain and patients with special regional therapy benefited only partially after the introduction and an increase in pain intensity was even observed. The quality of care was improved by standardization of the postoperative pain management. The legal and practical ability of the nursing stuff to administer pain medication within well-defined margins reduced the dependence on the ward doctor and at the same time patient pain levels. Patients received analgesics more quickly and experienced increased effectiveness. These results should be an incentive to reconsider the importance of the organization of postoperative pain management, because the quality of care with all potential medical and economic advantages, can be easily optimized by such simple mechanisms. They also show that the quality assessment of acute pain and the selection of appropriate indicators

Organizational culture is also considered as an effective factor in the performance of many organizations. The main goal of the present study was to determine the relationship of Centralization and organizational culture and performance indexes in Teaching Hospitals affiliated to Tehran University of Medical Sciences. This correlation study was performed in the year 2007. The population studied consisted of 4408 personnel from 13 hospitals among whom 441 subjects were selected and studied via a class sampling method. Data was compiled using a check list concerning the evaluation status of Centralization and another form concerning performance indexes as well as Robbin's organizational culture questionnaire. Data were obtained from the subjects by self answering and analyzed by using descriptive statistical indexes, T- test and Fisher's exact tests. Among the organizational culture indexes of the hospitals studied, control and organizational identity was better as compared to others (mean=3.32 and 3.30). Concerning the extent of Centralization in the hospitals studied, 53.85 % and 46.15 % were reported to have upper and lower organizational Centralization, respectively. Mean ratio of surgical operations to inpatients was 40%, the mean rate of admissions per active bed was 60.83, mean bed occupancy coefficient was 70.79%, average length of stay was 6.96 days, and mean net death rate was 1.41%. No significant correlation was seen between Centralization degree, organizational culture and performance indexes in teaching hospitals Tehran university of medical sciences. (with 95% confidence interval). Due to the fact that first grade Teaching hospitals use board certified members, expert personnel, and advanced equipments and because of the limitation of patients choice and, the extent of Centralization and many organizational culture components have no significant

    The growth and destruction of a volcanic edifice reflects dynamic processes that shape the Earth, including transport of mass and heat in a cooling planet versus the mechanical and chemical degradation of igneous material driving toward equilibrium. Central to understanding the nature of volcanoes are determinations of the rates of change in the volumes of these features. Through a quantitative temporal framework it is possible to elucidate the relative importance of competing processes that govern growth and destruction of volcanoes, e.g., magma production versus mass wasting. As the energetics of constructive and destructive processes are directly linked to the hazards that they pose to human populations and because volcanoes are stochastic systems, the only means of long-term forecast is via comprehensive understanding of volcanic history. Mount Cameroon is one of Africa's largest volcanoes and is currently the only active centre on the Cameroon line. The edifice is 4 km high with a volume of at least 1200 km3. Seventeen eruptions have been reported since 1800 and a time-averaged eruption volume of 6 x 106 m3/year is calculated from 7 eruptions over the past 91 years. Eight new Ar/Ar ages have been determined for basaltic rocks distributed across Mt. Cameroon; plateau ages are 4139±19 ka, 195±2 ka, 187±5 ka, 161±2 ka, 82±4, 68±3, 14±4 and 2±4 ka (1σ). The upper age from this set defines the oldest age yet measured for the Mt. Cameroon system. The data demonstrate activity through the mid to upper Pleistocene, continuing through to modern activity. Using recent estimates for basin-wide erosion of ca. 0.05 mm/a on a similar edifice (Kauai, Hawaii, Gayer et al 2008) and extrapolating over the Mt. Cameroon edifice yields an erosion rate of 5x104 m3/a, a factor of 30 times lower than the modern magma production rate. Considering these two fluxes implies that approximately 700 ka is required to construct an edifice of 1200 km3 (the current volume of Mt

    In a period of 10 years seven patients with open injury to the heart were treated. Their ages ranged from 17 to 39 years. One patient had a gunshot injury, in six the injury was inflicted with a knife. In three patients the injuries were combined (concurrent injury to the lung in 2 and to the diaphragm in one) and in four isolated. Perforating injury of both ventricles and damage of the interventricular septum were found in one case. All patients underwent emergency closure of the heart wounds with an atraumatic synthetic thread and drainage of the pleural cavity. Complications developed in the postoperative period in six patients: suppuration of the operative wound in one and pericarditis in five. One patient died. Analysis of the obtained data testifies to the expediency of two-stage treatment with rehabilitation in cardiological departments. This shortens the period of rehabilitation of patients with open injuries to the heart treated in a central regional hospital.

    This retrospective, cross-sectional study was carried out to evaluate the quality of 2208 outpatient prescriptions in a central hospital in the West Bank, Palestine. The physicians' handwriting was poorly readable or illegible in one-third of the prescriptions. The prescriber's name and signature and patient's name were mentioned in almost all orders whereas the patient's age was stated in 54.9%. The vast majority of physicians (95.5%) prescribed drugs using their trade (brand) names. Drug strength, quantity and dose/frequency were stated in 61.1%, 76% and 73.8% of prescriptions respectively. Only 33 prescriptions (1.5%) contained full directions for use for all drugs. Correlation analysis revealed that the presence of certain prescription elements was statistically significantly associated with the clinic of origin and the number of drugs prescribed. The overall poor legibility and incompleteness of the prescriptions is of concern.

    Carbon dioxide was blamed for the deaths of around 1700 people in Cameroon, west Africa, in 1986 when a massive release of gas occurred from Lake Nyos, a volcanic crater lake. The clinical findings in 845 survivors seen at or admitted to hospital were compatible with exposure to an asphyxiant gas. Rescuers noted cutaneous erythema and bullae on an unknown proportion of corpses and 161 (19%) survivors treated in hospital; though these lesions were initially believed to be burns from acidic gases, further investigation suggested that they were associated with coma states caused by exposure to carbon dioxide in air. The disaster at Lake Nyos and a similar event at Lake Monoun, Cameroon, two years previously provide new information on the possible medical effects of large scale emissions of carbon dioxide, though the presence of other toxic factors in these gas releases cannot be excluded.

    Background Studies in different parts of the world have implicated money as a vehicle for transmission of pathogens. Such information which is necessary to facilitate infection control strategies is lacking in many sub-Saharan countries including Cameroon. This study analyzed the Franc de la Communauté Financiere d’Afrique (Franc CFA), the currency used in Cameroon and other countries in the Central African sub-region, as a potential vehicle for transmission of pathogenic bacteria and fungi, particularly drug-resistant strains, to generate findings which could create awareness on currency contamination and serve as a guide when formulating health policies on currency. Methods Two hundred and thirteen currency samples representing various denominations of notes and coins randomly collected from diverse sources in Buea, Cameroon were analyzed for bacteria and fungi. The sensitivity of bacterial isolates to antibiotics was tested using the disc diffusion method. The relationship between contamination and physical state, source or denomination of currency was assessed using the χ2 test. All statistics were discussed at 0.05 significance level. Results Two hundred (93.9%) samples were contaminated with notes (96.6%) showing higher contamination than coins (88.2%). Uncirculated (mint) samples showed no contamination. There was a significant difference (P˂0.05) in contamination with respect to currency denomination, physical state and source. All samples from butchers and patients/personnel in hospitals were contaminated. Lower denominations showed significantly higher (P = 0.008) levels of contamination than higher denominations. Dirty currency was more contaminated than clean currency. Nine bacterial species were isolated. Coagulase-negative Staphylococcus (CoNS) (54.9%) and Staphylococcus aureus (20.1%) predominated.

    Racial disparities have been suggested in hospital utilization and outcome for lung cancer surgery, but the effect of hospital centralization on closing this gap is unknown. We hypothesized that centralization has increased the utilization of high- or very-high-volume (HV/VHV) hospitals, a proxy for access to high-quality care, over the study period independently from race.Inpatient records were extracted from the New York Statewide Planning and Research Cooperative System database (1995-2012) according to Clinical Modification of the International Classification of Diseases, 9th Revision diagnosis codes 162.* and 165.* and surgical procedure codes 32.2-32.6 (n = 31,931). Patients treated exclusively with surgery of black or white race with a valid zip code were included. Logistic models were performed to determine factors associated with utilization of HV/VHV or low- or very-low-volume (LV/VLV) hospitals; these models were subsequently stratified by race.The percentage of both black and white patients utilizing HV/VHV hospitals increased over the study period (+22.7% and 13.9%, respectively). The distance to the nearest HV/VHV hospital and patient-hospital distance were significantly lower in black compared to white patients, however, blacks were consistently less likely to use HV/VHV than whites (odds ratioadj: 0.26; 95% confidence interval: 0.23-0.29), and were significantly more likely to utilize urban, teaching, and lower volume hospitals than whites. Likelihood of HV/VHV utilization decreased with an increasing distance from a HV/VHV hospital, overall and separately for black and white patients.Although centralization has increased the utilization of HV/VHV for both black and white patients, racial differences in access and utilization of HV hospitals persisted.

    The purpose of this study was to determine the profile of women who give unassisted natural home childbirth (UNHC) in Brazzaville and to evaluate maternal and perinatal morbidity and mortality. This prospective descriptive study was carried out at the Maternity Clinic of the Talangaï Central Hospital (TCH) from November 1, 2006 to October 31, 2008. Women who gave UNHC and were afterwards admitted to the TCH. The frequency of UNHC was 3.7%. The 19- to 35-year age bracket accounted for 72.6% of cases. The main causes underlying UNHC were ignorance of the initial clinical signs of labor for 37 of the 61 primipares (60.7%) and waiting for onset of labor before going to the hospital for 167 of the 360 paucipares and multipares (46.4%). For 234 women, UNHC occurred after pregnancy without prenatal care. In 57.8% of these cases, the reason for admission after UNCR was hemorrhage. More than half of the women (56.8%) who gave UNHC lived women live near a medical facility. Term pregnancies accounted for 41.3% cases of UNHC and undetermined term for 34.4%. At least one maternal complication was observed in 65.3% of cases. Neonatal morbidity was observed in 24% of cases and perinatal mortality in 11.4%. UNHC is still common in Brazzaville owing mainly to poor public awareness. Public information campaigns to educate women to recognize the initial signs of labor could decrease the frequency of UNHC.

    Coronavirus (CoV) infections induce respiratory tract illnesses and central nervous system (CNS) diseases. We aimed to explore the cytokine expression profiles in hospitalized children with CoV-CNS and CoV-respiratory tract infections. A total of 183 and 236 hospitalized children with acute encephalitis-like syndrome and respiratory tract infection, respectively, were screened for anti-CoV IgM antibodies. The expression profiles of multiple cytokines were determined in CoV-positive patients. Anti-CoV IgM antibodies were detected in 22/183 (12.02%) and 26/236 (11.02%) patients with acute encephalitis-like syndrome and respiratory tract infection, respectively. Cytokine analysis revealed that the level of serum granulocyte colony-stimulating factor (G-CSF) was significantly higher in both CoV-CNS and CoV-respiratory tract infection compared with healthy controls. Additionally, the serum level of granulocyte macrophage colony-stimulating factor (GM-CSF) was significantly higher in CoV-CNS infection than in CoV-respiratory tract infection. In patients with CoV-CNS infection, the levels of IL-6, IL-8, MCP-1, and GM-CSF were significantly higher in their cerebrospinal fluid samples than in matched serum samples. To the best of our knowledge, this is the first report showing a high incidence of CoV infection in hospitalized children, especially with CNS illness. The characteristic cytokine expression profiles in CoV infection indicate the importance of host immune response in disease progression. © 2017 S. Karger AG, Basel.

    HIV/AIDS is a major public health problem in Cameroon and Africa, and the challenges of orphans and vulnerable children are a threat to child survival, growth and development. The HIV prevalence in Cameroon was estimated at 5.1% in 2010. The objective of this study was to assess the burden of orphans and vulnerable children due to HIV/AIDS in Cameroon. A structured search to identify publications on orphans and other children made vulnerable by AIDS was carried out. A traditional literature search on google, PubMed and Medline using the keywords: orphans, vulnerable children, HIV/AIDS and Cameroon was conducted to identify potential AIDS orphans publications, we included papers on HIV prevalence in Cameroon, institutional versus integrated care of orphans, burden of children orphaned by AIDS and projections, impact of AIDS orphans on Cameroon, AIDS orphans assisted through the integrated care approach, and comparism of the policies of orphans care in the central African sub-region. We also used our participatory approach working experience with traditional rulers, administrative authorities and health stakeholders in Yaounde I and Yaounde VI Councils, Nanga Eboko Health District, Isangelle and Ekondo Titi Health Areas, Bafaka-Balue, PLAN Cameroon, the Pan African Institute for Development-West Africa, Save the orphans Foundation, Ministry of Social Affairs, and the Ministry of Public Health. Results show that only 9% of all OVC in Cameroon are given any form of support. AIDS death continue to rise in Cameroon. In 1995, 7,900 people died from AIDS in the country; and the annual number rose to 25,000 in 2000. Out of 1,200,000 orphans and vulnerable children in Cameroon in 2010, 300,000(25%) were AIDS orphans. Orphans and the number of children orphaned by AIDS has increased dramatically from 13,000 in 1995 to 304,000 in 2010. By 2020, this number is projected to rise to 350,000.

    Nearly three decades after its discovery, HIV infection remains the number one killer disease in Sub- Saharan Africa where up to 67% of the world's 33 million infected people live. In Cameroon, based on a Demographic Health Survey carried out in 2004, the national HIV prevalence is estimated at 5.5% with women and youths being predominantly infected. Orphans and vulnerable children (OVC) from the HIV and AIDS pandemic have increased steadily over the years; hospital occupancy is estimated at about 30%, hence stretching the health system; co-infections like HIV/tuberculosis have been reported to reach 40-50% of infected cases and 95% of teachers are said not to be productive on several counts. Thus, the impact is multi-sectorial. Furthermore, the HIV epidemic in Cameroon is peculiar because of the wide HIV-1 genetic diversity of HIV-1 Group M observed with several subtypes reported (A, B, C, D, F, G, H, J, K), predominantly subtype A. There are also circulating recombinant forms, mainly CRF02_AG. In addition, HIV-1 Groups O and N have all been noted in Cameroon. These findings have great implications not only for HIV diagnosis, but also for responsiveness to therapy as well as for vaccine development. In 1986, the initial response of the Cameroon government to the increasing trends in the HIV/AIDS infection was to create a National AIDS Control Committee to coordinate a national AIDS programme. By 2000, the first National Strategic Plan was drawn for 2000-2005. The second National Strategic Plan for 2006-2010 is currently being implemented and covers various axes. Some results obtained show that there has been significantly positive outcomes noted in the various arms of intervention by the Cameroon government.

  10. Crop yield gaps in Cameroon.

    Although food crop yields per hectare have generally been increasing in Cameroon since 1961, the food price crisis of 2008 and the ensuing social unrest and fatalities raised concerns about the country's ability to meet the food needs of its population. This study examines the country's potential for increasing crop yields and food production to meet this food security challenge. Fuzzy set theory is used to develop a biophysical spatial suitability model for different crops, which in turn is employed to ascertain whether crop production is carried out in biophysically suited areas. We use linear regression to examine the trend of yield development over the last half century. On the basis of yield data from experimental stations and farmers' fields we assess the yield gap for major food crops. We find that yields have generally been increasing over the last half century and that agricultural policies can have significant effects on them. To a large extent, food crops are cultivated in areas that are biophysically suited for their cultivation, meaning that the yield gap is not a problem of biophysical suitability. Notwithstanding, there are significantly large yield gaps between actual yields on farmers' farms and maximum attainable yields from research stations. We conclude that agronomy and policies are likely to be the reasons for these large yield gaps. A key challenge to be addressed in closing the yield gaps is that of replenishing and properly managing soil nutrients.

    For advanced out-of-hospital airway management, skilled personnel and adequate equipment are key prerequisites. There are little data on the current availability of airway management equipment and standards of medical staff on Helicopter Emergency Medical System (HEMS) helicopters in central Europe. An internet search identified all HEMS helicopters in Austria, Switzerland and Luxembourg. We identified 15 HEMS helicopter bases in Switzerland, 28 in Austria and three in Luxembourg. A questionnaire was sent to all bases, asking both for the details of the clinical background and experience of participating staff, and details of airway management equipment carried routinely on board. Replies were received from 14 helicopter bases in Switzerland (93%), 25 bases in Austria (89%) and all three bases in Luxembourg. Anaesthesiologists were by far the most frequent attending physicians (68-85%). All except one bases reported to have at least one alternative supraglottic airway device. All bases had capnometry and succinylcholine. All bases in the study except two in Austria had commercial pre-packed sets for a surgical airway. All helicopters were equipped with automatic ventilators, although not all were suitable for non-invasive ventilation (NIV; Switzerland: 43%, Austria: 12%, Luxembourg: 100%). Masks for NIV were rarely available in Switzerland (two bases; 14%) and in Austria (three bases; 12%), whereas all three bases in Luxembourg carried those masks. Most HEMS helicopters carry appropriate equipment to meet the demands of modern advanced airway management in the pre-hospital setting. Further work is needed to ensure that appropriate airway equipment is carried on all HEMS helicopters.

    The Cameroon Volcanic Line (CVL) is a major geologic feature that cuts across Cameroon from the south west to the north east. It is a unique volcanic lineament which has both an oceanic and a continental sector and consists of a chain of Tertiary to Recent, generally alkaline volcanoes stretching from the Atlantic island of Pagalu to the interior of the African continent. The oceanic sector includes the islands of Bioko (formerly Fernando Po) and Sao Tome and Principe while the continental sector includes the Etinde, Cameroon, Manengouba, Bamboutos, Oku and Mandara mountains, as well as the Adamawa and Biu Plateaus. In addition to the CVL, three other major tectonic features characterize the region: the Benue Trough located northwest of the CVL, the Central African Shear Zone (CASZ), trending N70 degrees E, roughly parallel to the CVL, and the Congo Craton in southern Cameroon. The origin of the CVL is still the subject of considerable debate, with both plume and non-plume models invoked by many authors (e.g., Deruelle et al., 2007; Ngako et al, 2006; Ritsema and Allen, 2003; Burke, 2001; Ebinger and Sleep, 1998; Lee et al, 1994; Dorbath et al., 1986; Fairhead and Binks, 1991; King and Ritsema, 2000; Reusch et al., 2010). Crustal structure beneath Cameroon has been investigated previously using active (Stuart et al, 1985) and passive (Dorbath et al., 1986; Tabod, 1991; Tabod et al, 1992; Plomerova et al, 1993) source seismic data, revealing a crust about 33 km thick at the south-western end of the continental portion of the CVL (Tabod, 1991) and the Adamawa Plateau, and thinner crust (23 km thick) beneath the Garoua Rift in the north (Stuart et al, 1985) (Figure 1). Estimates of crustal thickness obtained using gravity data show similar variations between the Garoua rift, Adamawa Plateau, and southern part of the CVL (Poudjom et al., 1995; Nnange et al., 2000). In this study, we investigate further crustal structure beneath the CVL and the adjacent regions in

    Background The aim of this study was to analyzed the characteristics and treatment of maxillofacial injuries in the elder patients with maxillofacial injuries in central China. Material and Methods We retrospectively analyzed the characteristics and treatment of maxillofacial injuries in the patients over the age of 60 to analyze the trends and clinical characteristics of maxillofacial trauma in elder patients from the First Affiliated Hospital of Zhengzhou University (from 2010 to 2013) in central China and to present recommendations on prevention and management. Results Of the 932 patients with maxillofacial injuries, 126 aged over 60 years old accounting for 13.52% of all the patients (male:female, 1.74:1; mean age, 67.08 years old). Approximately 52% of the patients were injured by falls. The most frequently observed type of injuries was soft tissue injuries (100%), followed by facial fractures (83.05%). Of the patients with soft tissue injuries, the abrasions accounted the most, followed by lacerations. The numbers of patients of midface fracture (60 patients) were almost similar to the number of lower face fractures (66 patients). Eighty two patients (65.08%%) demonstrated associated injuries, of which craniocerebral injuries were the most prevalent. One hundred and four patients (82.54%) had other systemic medical conditions, with cardiovascular diseases the most and followed by metabolic diseases and musculoskeletal conditions. Furthermore, the study indicated a relationship between maxillofacial fractures and musculoskeletal conditions. Only 13 patients (10.32%) sustained local infections, of whom had other medical conditions. Most of the facial injuries (85.71%) in older people were operated including debridement, fixing loose teeth, reduction, intermaxillary fixation and open reduction and internal fixation (ORIF). Conclusions Our analysis of the characteristics of maxillofacial injuries in the elder patents may help to promote clinical research to

    Introduction Ninety-two percent of Low Birth Weight(LBW) infants are born in developing countries, 70% in Asia and 22% in Africa. WHO and UNICEF estimate LBW in Kenya as11% and 6%by 2009 Kenya Demographic Health Survey. The same survey estimated LBW to be 5.5% in Central Province, Kenya. Data in Olkalou hospital indicated that prevalence of LBW was high. However, factors giving rise to the problem remained unknown. Methods A cross-sectional analytic study was therefore conducted to estimate prevalence and distribution and determine the factors associated with LBW in the hospital. LBW was defined as birth of a live infant less than 2500g. We collected data using a semi-structured questionnaire and review of health records. A total 327 women were randomly selected from 500mothers. Data was managed using Epi Info 3.3.2. Results The prevalence of LBW was 12.3% (n=40). The mean age of mothers was 25.6±6.2 years. Mean birth weight was 2928±533 grams. There were 51.1% (n=165) male neonates and 48.9% (n=158) females. The following factors were significantly associated with LBW:LBW delivery in a previous birth (OR=4.7, 95%C.I.=1.53-14.24), premature rapture of membranes (OR=2.95, 95%C.I.=1.14-7.62), premature births (OR=3.65, 95%C.I.=1.31-10.38), and female newborn (OR=2.32, 95%C.I.=1.15-4.70). On logistic regression only delivery of LBW baby in a previous birth (OR=5.07, 95%C.I.=1.59-16.21) and female infant (OR=3.37, 95%C.I.=1.14-10.00)were independently associated with LBW. Conclusion Prevalence of LBW in the hospital was higher than national estimates. Female infant and LBW baby in a previous birth are independent factors. Local prevention efforts are necessary to mitigate the problem. Population-based study is necessary to provide accurate estimates in the area. PMID:26090056

    Bovine Bacillus anthracis isolates from Cameroon were genetically characterized. They showed a strong homogeneity, and they belong, together with strains from Chad, to cluster Aβ, which appears to be predominant in western Africa. However, one strain that belongs to a newly defined clade (D) and cluster (D1) is penicillin resistant and shows certain phenotypes typical of Bacillus cereus. PMID:21705535

    Objective. To detect genes encoding carbapenem resistance among Enterobacter species in a tertiary care hospital in central India. Methods. Bacterial identification of Enterobacter spp. isolates from various clinical specimens in patients admitted to intensive care units was performed by routine conventional microbial culture and biochemical tests using standard recommended techniques. Antibiotic sensitivity test was performed by standard Kirby Bauer disc diffusion technique. PCR amplification and automated sequencing was carried out. Transfer of resistance genes was determined by conjugation. Results. A total of 70/130 (53.84%) isolates of Enterobacter spp. were found to exhibit reduced susceptibility to imipenem (diameter of zones of inhibition ≤13 mm) by disc diffusion method. Among 70 isolates tested, 48 (68.57%) isolates showed MIC values for imipenem and meropenem ranging from 32 to 64 mg/L as per CLSI breakpoints. All of these 70 isolates were found susceptible to colistin in vitro as per MIC breakpoints (<0.5 mg/L). PCR carried out on these 48 MBL (IP/IPI) E-test positive isolates (12 Enterobacter aerogenes, 31 Enterobacter cloacae, and 05 Enterobacter cloacae complex) was validated by sequencing for beta-lactam resistance genes and result was interpreted accordingly. Conclusion. The study showed MBL production as an important mechanism in carbapenem resistance in Enterobacter spp. and interspecies transfer of these genes through plasmids suggesting early detection by molecular methods.

All the intramural deliveries between 1 January 2005 and 31 July 2007 comprised 9386 births and their 9324 mothers (62 mothers gave birth to twin babies). The newborns were examined and assessed systematically for the presence of congenital anomalies, system wise distribution of anomalies and risk factors attributable. Out of the total 9386 deliveries, 9194 were live births and 192 were stillbirths. The total number of babies with congenital malformations was 179 (1.91%). Out of the 9262 singleton births, 177 (1.05%) were malformed, whereas 2 of the 62 pairs of twins had birth defects. Nine of the 179 malformed babies (5.02%) were still born. Prematurity, increased maternal age, increasing birth order and low birth weight were found to have a higher risk of congenital anomalies. Cardiovascular malformations were most common in live births, followed by musculoskeletal and genitourinary anomalies. Congenital anomalies are a major cause of stillbirths and infant mortality. Evaluation of cardiovascular system to rule out congenital heart disease in high-risk mothers' babies is the important factor to be considered.

    The HIV pandemic disseminated globally from Central West Africa, beginning in the second half of the twentieth century. To elucidate the virologic origins of the pandemic, a cross-sectional study was conducted of the genetic diversity of HIV-1 strains in villagers in 14 remote locations in Cameroon and in hospitalized and STI patients. DNA extracted from PBMC was PCR amplified from HIV(+) subjects. Partial pol amplicons (N = 164) and nearly full virus genomes (N = 78) were sequenced. Among the 3956 rural villagers studied, the prevalence of HIV infection was 4.9%; among the hospitalized and clinic patients, it was 8.6%. Virus genotypes fell into two distinctive groups. A majority of the genotyped strains (109/164) were the circulating recombinant form (CRF) known to be endemic in West Africa and Central West Africa, CRF02_AG. The second most common genetic form (9/164) was the recently described CRF22_01A1, and the rest were a collection of 4 different subtypes (A2, D, F2, G) and 6 different CRFs (-01, -11, -13, -18, -25, -37). Remarkably, 10.4% of HIV-1 genomes detected (17/164) were heretofore undescribed unique recombinant forms (URF) present in only a single person. Nearly full genome sequencing was completed for 78 of the viruses of interest. HIV genetic diversity was commonplace in rural villages: 12 villages each had at least one newly detected URF, and 9 villages had two or more. These results show that while CRF02_AG dominated the HIV strains in the rural villages, the remainder of the viruses had tremendous genetic diversity. Between the trans-species transmission of SIVcpz and the dispersal of pandemic HIV-1, there was a time when we hypothesize that nascent HIV-1 was spreading, but only to a limited extent, recombining with other local HIV-1, creating a large variety of recombinants. When one of those recombinants began to spread widely (i.e. became epidemic), it was recognized as a subtype. We hypothesize that the viruses in these remote Cameroon

    Increasingly, peripherally inserted central venous catheters (PICCs) are placed for prolonged intravenous access. Few data exist regarding risk factors for central line-associated bloodstream infection (CLABSI) complicating PICCs in hospitalized children, especially children hospitalized outside the intensive care unit (ICU). We identified all children with a PICC inserted at The Johns Hopkins Hospital (Baltimore, MD) from 1 January 2003 through 31 December 2009 and used Poisson regression models to identify risk factors for PICC-associated CLABSIs. A total of 2592 PICCs were placed in 1819 children. One hundred sixteen CLABSIs occurred over 44,972 catheter-days (incidence rate [IR], 2.58 cases per 1000 catheter-days; 95% confidence interval [CI], 2.07-3.00 cases per 1000 catheter-days). Independent predictors of CLABSI in the entire cohort included PICC dwell time of > 21 days (IR ratio [IRR], 1.53; 95% CI, 1.05-2.26), parenteral nutrition as indication for insertion (IRR, 2.24; 95% CI, 1.31-3.84), prior PICC-associated CLABSI (IRR, 2.48; 95% CI, 1.18-5.25), underlying metabolic condition (IRR, 2.07; 95% CI, 1.14-3.74), and pediatric ICU exposure during hospitalization (IRR, 1.80; 95% CI, 1.18-2.75). Risk factors for CLABSI in children without PICU exposure included younger age, underlying malignancy and metabolic conditions, PICCs inserted in the lower extremity, and a prior PICC-associated CLABSI. Prolonged catheter dwell time, pediatric ICU exposure, and administration of parenteral nutrition as the indication for PICC insertion are important predictors of PICC-associated CLABSI in hospitalized children. A careful assessment of these risk factors may be important for future success in preventing CLABSIs in hospitalized children with PICCs.

  9. The unfortunate sufferer: discursive dynamics around pregnancy loss in Cameroon.

    Pregnancy losses are ambiguous affairs in East Cameroon. Childbearing is not always people's primary aim within their fragile sexual and marital relationships, and it is often unclear to outsiders whether a pregnancy interruption is intended or unintended. Drawing on 15 months of fieldwork, I explore the discursive strategies Gbigbil women deploy while navigating such ambiguities around interrupted pregnancies. Suffering is central to their defensive discourses. Depending on the stakes in their relationships, women foreground the notion of suffering either to portray themselves as moral and innocent--and maintain social status or raise support--or to allude to or acknowledge their intention to terminate a pregnancy. This dynamic deployment of a suffering discourse reveals the interconnections of unintended and intended pregnancy losses, and of suffering (associated especially with the former) and agency (often associated with the latter).

    Ocular trauma is a major cause of visual loss, but little is known about its epidemiology and clinical characteristics in China. The aim of this study was to determine the prevalence and clinical characteristics of ocular trauma and assess prognostic factors in Changsha, Hunan, located in South-Central China. A retrospective case series (ICD codes: S05) study of ocular trauma in patients was performed at the Second Xiangya Hospital, Central South University, from 1 January 2010 to 31 December 2014. Demographic information, injury causes, ocular trauma types and initial and final visual acuity (VA) were recorded and analysed. The ocular trauma score (OTS) was calculated to assess the extent of the eye injury, prognosis and factors associated with visual impairment. All patient data were collected from the medical records system. Of the 2009 patients presenting during this 5-year period, 1695 (84.4%) were males and 314 (15.6%) were females. The average age of all patients was 37.0 ± 19.3 years (range from 1 to 87 years). The age distribution showed a peak in the ocular trauma population in the 41- to 50-year age group (24%, n = 482), followed by the 51- to 60-year age group (16.9%, n = 339). Overall, open-globe injuries had a higher frequency (70.7%, n = 1420) than closed-globe injuries (28.6%, n = 575) and thermal/chemical injuries (0.7%, n = 14). Of the open-globe injuries, corneal penetration was the most common injury (32.2%, n = 646) followed by rupture (21.5%, n = 432) and an intraocular foreign body (16.2%, n = 325). Overall, the most frequent ocular trauma setting was the workplace (39.6%, n = 795), followed by the home (28.4%, n = 570), and the most frequent activity was ironwork. Firecracker- and firework-associated ocular trauma was significantly higher during the months of January and February than during other months (50.0%, n = 112, p < 0.001). In patients under 18 years, the most frequently occurring injury was open globe

    We investigate the lithospheric structure of Cameroon inverting Rayleigh waves obtained from the cross-correlation of ambient seismic noise. We correlate seismic records between 32 broad-band stations and we obtain good quality Rayleigh waves for 310 interstation paths. We measure group velocity dispersion curves from the reconstructed Rayleigh waves in the period range 10-35 s and we invert the group velocities for tomographic images. After the tomography the group velocities are then inverted, together with longer period group velocity measurements from existing literature, to compute a 3-D S-wave velocity model of the Cameroon lithosphere down to 100 km depth. Our results provide an unprecedented mapping of the physical properties of the different crustal units and their correlations with surface geology, as well as with mantle lithospheric variations. The Cameroon Volcanic Line (CVL) appears as a segmented feature exhibiting different physical properties along strike. The active Mt Cameroon volcano is underlain by very low velocities, unlike the other segments of the CVL. The along-strike variations in crustal structure suggest that lateral heterogeneities in lithospheric thickness and physical properties have influenced the location and distribution of magmatism. The crust beneath the Central African Shear Zone exhibits a sizeable low velocity anomaly. The lithosphere beneath Cameroon is characterised by a heterogeneous crust with a relatively constant thickness and a low velocity uppermost mantle at the edge of the Congo Craton. Our results favour processes combining small-scale upwelling at the edge of a thick lithosphere and reactivation of Precambrian basement structures to explain the distribution of Holocene-Recent magmatism and plateau uplift. Our results also indicate that Mt Cameroon and surroundings areas are the most at risk zones for magmatic activity during this stage of CVL development.

    Injury is a significant and increasingly common cause of morbidity and mortality in sub-Saharan Africa; however, the social and economic factors underlying these trends are not well understood. We evaluated the relationship between socioeconomic status (SES) and trauma outcomes using a prospective registry of patients presenting to the largest trauma hospital in Yaoundé, Cameroon. Trauma patients (n=2855) presenting to the emergency ward at Central Hospital, Yaoundé between April 15 and October 15, 2009 were surveyed regarding demographic and socioeconomic background, nature and severity of injuries, treatment, and disposition. A wealth score was estimated for each patient, corresponding to an SES index constructed using principle components analysis of the urban Cameroonian Demographic and Health Survey. Logistic regression was used to evaluate the effects of SES on care-seeking behaviour, injury severity, and treatment outcome. SES wealth score, care-seeking prior to visiting hospital, injury severity, treatment outcome. Patients aged 1-89 presented with road traffic injuries (59.83%), falls (7.76%), and penetrating trauma (6.16%), and had higher SES than the broader urban Cameroonian population. Within the Yaoundé sample, being in the lowest SES quintile was associated with an increased likelihood of having sought care elsewhere before presenting to the hospital (aOR=3.28, p<0.001), after controlling for background and injury characteristics. Patients in the lowest SES quintile were also more likely to present with moderate/severe injuries (aOR=4.93, p<0.001), and were more likely to be transferred to the operating room. Patients presenting to this trauma centre were wealthier than the broader community, suggesting the possibility of barriers to accessing care. Poorer patients were more likely to have severe injuries and more likely to need surgery, but were less likely to seek care from a major trauma centre immediately. Substantial differences in SES

    Background Infectious diseases of the central nervous system (CNS) remain common and life-threatening, especially in developing countries. Knowledge of the aetiological agents responsible for these infections is essential to guide empiric therapy and develop a rational public health policy. To date most data has come from patients admitted to tertiary referral hospitals in Asia and there is limited aetiological data at the provincial hospital level where most patients are seen. Methods We conducted a prospective Provincial Hospital-based descriptive surveillance study in adults and children at thirteen hospitals in central and southern Viet Nam between August 2007– April 2010. The pathogens of CNS infection were confirmed in CSF and blood samples by using classical microbiology, molecular diagnostics and serology. Results We recruited 1241 patients with clinically suspected infection of the CNS. An aetiological agent was identified in 640/1241 (52%) of the patients. The most common pathogens were Streptococcus suis serotype 2 in patients older than 14 years of age (147/617, 24%) and Japanese encephalitis virus in patients less than 14 years old (142/624, 23%). Mycobacterium tuberculosis was confirmed in 34/617 (6%) adult patients and 11/624 (2%) paediatric patients. The acute case fatality rate (CFR) during hospital admission was 73/617 (12%) in adults and to 42/624 (7%) in children. Conclusions Zoonotic bacterial and viral pathogens are the most common causes of CNS infection in adults and children in Viet Nam. PMID:22662232

    In Greece more than 14,000 tonnes of infectious hospital waste are produced yearly; a significant part of it is still mismanaged. Only one off-site licensed incineration facility for hospital wastes is in operation, with the remaining of the market covered by various hydroclave and autoclave units, whereas numerous problems are still generally encountered regarding waste segregation, collection, transportation and management, as well as often excessive entailed costs. Everyday practices still include dumping the majority of solid hospital waste into household disposal sites and landfills after sterilization, still largely without any preceding recycling and separation steps. Discussed in the present paper are the implemented and future treatment practices of infectious hospital wastes in Central Macedonia; produced quantities are reviewed, actual treatment costs are addressed critically, whereas the overall situation in Greece is discussed. Moreover, thermal treatment processes that could be applied for the treatment of infectious hospital wastes in the region are assessed via the multi-criteria decision method Analytic Hierarchy Process. Furthermore, a sensitivity analysis was performed and the analysis demonstrated that a centralized autoclave or hydroclave plant near Thessaloniki is the best performing option, depending however on the selection and weighing of criteria of the multi-criteria process. Moreover the study found that a common treatment option for the treatment of all infectious hospital wastes produced in the Region of Central Macedonia, could offer cost and environmental benefits. In general the multi-criteria decision method, as well as the conclusions and remarks of this study can be used as a basis for future planning and anticipation of the needs for investments in the area of medical waste management.

    BACKGROUND The purpose of this study was to evaluate preoperative and intraoperative blood transfusion practices in Hospital Central (Maputo, Mozambique) and estimate the number of potentially avoidable transfusions. STUDY DESIGN AND METHODS A retrospective cohort study was performed. Age, comorbidities, hemoglobin, the potential for blood loss, and units of packed red blood cell (RBC) transfusions were recorded. Preoperative transfusions were evaluated to determine whether they met criteria established by the Mozambican Ministry of Health as well as proposed guidelines based on more restrictive protocols. Avoidable blood transfusions were defined as those preoperative transfusions that were not indicated based on these guidelines. Multivariate logistic regression was used to identify factors that predicted transfusion. RESULTS Two-hundred and five patients (age range: 0.1 - 86 years) underwent surgery in the main operating room during the two-week study period. Overall, thirty-five (17%) patients received sixty-eight transfusions. Of these, thirty-six transfusions were given preoperatively and thirty-two were given intraoperatively. Thirty-six percent of preoperative transfusions were avoidable according to national guidelines. Ninety-two percent were avoidable using more restrictive guidelines. The primary predictors of preoperative blood transfusion were lower hemoglobin (odd's ratio 0.390 / 1 g/dl; p<0.0001) and the potential for blood loss (odd's ratio 3.73; p=0.0410). CONCLUSIONS Adherence to existing hemoglobin thresholds recommended by national blood transfusion guidelines could significantly reduce the number of transfusions and the association risk of transfusion-transmissible infections. Adoption of more restrictive guidelines is recommended to further improve blood transfusion utilization and further reduce the transmission risk of HIV and hepatitis. PMID:23692441

    PurposeTo determine the incidence and the risks factors of peripherally inserted central catheter (PICC)-related infectious complications.Materials and MethodsMedical charts of every in-patient that underwent a PICC insertion in our hospital between January 2010 and October 2013 were reviewed. All PICC-related infections were recorded and categorized as catheter-related bloodstream infections (CR-BSI), exit-site infections, and septic thrombophlebitis.ResultsNine hundred and twenty-three PICCs were placed in 644 unique patients, mostly male (68.3 %) with a median age of 58 years. 31 (3.4 %) PICC-related infections occurred during the study period corresponding to an infection rate of 1.64 per 1000 catheter-days. We observed 27 (87.1 %) CR-BSI, corresponding to a rate of 1.43 per 1000 catheter-days, 3 (9.7 %) septic thrombophlebitis, and 1 (3.2 %) exit-site infection. Multivariate logistic regression analysis showed a higher PICC-related infection rate with chemotherapy (odds ratio (OR) 7.2–confidence interval (CI) 95 % [1.77–29.5]), auto/allograft (OR 5.9–CI 95 % [1.2–29.2]), and anti-coagulant therapy (OR 2.2–95 % [1.4–12]).ConclusionChemotherapy, auto/allograft, and anti-coagulant therapy are associated with an increased risk of developing PICC-related infections.Clinical AdvanceChemotherapy, auto/allograft, and anti-coagulant therapy are important predictors of PICC-associated infections. A careful assessment of these risk factors may be important for future success in preventing PICC-related infections.

    To assess the awareness and knowledge of glaucoma among people attending the ophthalmology outpatient department at a tertiary care hospital in central India. A prospective observational study. A questionnaire-based study was conducted, involving persons aged 18 and above attending the ophthalmology outpatient department from October 2014 to September 2015. Data on awareness and knowledge of glaucoma was collected through a face-to-face interview. Fourteen hundred people participated in the study. The mean age of participants was 43 ± 15 years (range, 18-85). The study participants included 53% men and 47% women. Only 27% (n = 380/1400) of the participants were aware of glaucoma. Age, sex, and presence or type of refractive error had no impact on glaucoma awareness. Awareness level was greater in individuals with higher education levels and those belonging to an upper socioeconomic class (SEC). Multiple logistic regression analysis revealed significantly higher levels of glaucoma awareness among participants belonging to the upper 2 SECs (P = 0.05) and those educated above the high school level (P = 0.001). The most common source of awareness was close acquaintance with relatives, famly members, and friends of glaucoma patients. Awareness of glaucoma in India is low. Lack of education and lower socioeconomic status are the major risk factors for late preentation of glaucoma. Continuous presence of a low level of awareness and the same factors accounting for it warrants the need for an aggressive and refined approach to increase awareness of glaucoma to prevent glaucoma-related blindness.

    Introduction Ophthalmic lesions show varied distribution on the basis of geographical location. Eye being a unique sensory organ needs to be studied both clinically and pathologically. Aim This study was aimed to evaluate the histomorphological and clinico-pathlological spectrum of ophthalmic lesions at a tertiary care hospital of Central India. Materials and Methods We reviewed all the ophthalmic biopsies performed in the Department of Pathology of our institute between January 2008 and November 2014. Total 488 biopsies of the orbito-ocular region were obtained from patients attending the ophthalmology department. Ophthalmic biopsies were studied as per epidemiological and histomorphological data. Results The patients ranged in age from one month to 85 years with bimodal distribution. With a male to female ratio of 1:1. Ophthalmic lesions were highest (44.8%) in less than 20 years age group. Eyelid (33.6%) was the most commonly involved site. Clinical diagnosis was consistent with histopathological diagnosis in approximately 76% cases. The non-neoplastic, benign and malignant lesions were 61.1%, 7.8% and 31.1% respectively. Retinoblastoma formed 40.1% of all malignant lesions followed by sebaceous carcinoma (19.1%) and Squamous Cell Carcinoma (SCC) (10.5%). Rare lesions were primary neuroblastoma of orbit and rhabdomyosarcoma of eyelid. Conclusion Findings suggest that among neoplastic lesions the most common ophthalmic malignancies were retinoblastoma in children and sebaceous carcinoma in adults. Among non-neoplastic lesions, 89% cases of infectious aetiology were of rhinosporidiosis in our study making it an important differential diagnosis among ophthalmic lesions. PMID:28273971

    Introduction Tumors of salivary glands are rare. According to Johns and Goldsmith in 1989, their annual incidence is less than 1/100000 without noteworthy geographical gap. But other authors suggest that their distribution may vary according to the race and geographical location. In Cameroon, existing studies give incomplete data. Hence, we underwent this study in order to draw the general profile of salivary gland tumors in Cameroon. Methods A retrospective study was carried out on the period spanning from January 2000 to December 2010 (11 years). It was done in nine Pathology services of different hospitals in Yaoundé, Douala and Bamenda. We consulted the archive registers of those services, retaining any patient with salivary gland tumor, whatever the histological type or location. Information gathered was the year of diagnosis, the service, the age and sex, the site of the tumor (gland) the histological type and the benign/ malignant character. Results We recruited a total of 275 files. Women were 56% (154/275) and men 44% (121/275) of the sample. Fifty eight tumors were malignant (21.9%) while 217 were benign (78.1%). The overall mean age was 37.44 years, with extremes between 1 and 84 years. Pleomorphic adenoma (60.36%) was the most common benign tumor. Adenoid cystic carcinoma (31%), mucoepidermoid carcinoma (22.4%) and adenocarcinoma (19%) were the most common malignant tumors. Palate (66.7%), cheek (30%) and lips (3.3%) were the sites were the minor salivary glands were mostly involved. Conclusion The differences with western world authors suggest a geographical variability of salivary gland tumors. PMID:27217890

    Objectives: To identify and describe the hospital disaster preparedness (HDP) in major private hospitals in Riyadh, Saudi Arabia. Methods: This is an observational cross-sectional survey study performed in Riyadh city, Saudi Arabia between December 2015 and April 2016. Thirteen major private hospitals in Riyadh with more than 100 beds capacity were included in this investigation. Results: The 13 hospitals had HDP plan and reported to have an HDP committee. In 12 (92.3%) hospitals, the HDP covered both internal and external disasters and HDP was available in every department of the hospital. There were agreements with other hospitals to accept patients during disasters in 9 facilities (69.2%) while 4 (30.8%) did not have such agreement. None of the hospitals conducted any unannounced exercises in previous year. Conclusion: Most of the weaknesses were apparent particularly in the education, training and monitoring of the hospital staff to the preparedness for disaster emergency occasion. Few hospitals had conducted an exercise with casualties, few had drilled evacuation of staff and patients in the last 12 months, and none had any unannounced exercise in the last year. PMID:28251227

    In December 1959 the Central Hospital for the Negev (today, the Soroka University Medical Center) opened its doors. This event was preceded by an arduous political battle over the Location of hospital facilities for inhabitants of Israel's south. On one side was the presiding Prime Minister David Ben-Gurion, who opposed the establishment of a hospital in Beer Sheba by the Clalit Sick Fund. On the other side were Beer Sheba's residents, led by David Tuviyahu--mayor of Beer Sheba, and Moshe Soroka--a member of the Clalit Sick Fund's management, who sought to bring about the immediate establishment of a hospital in the city itself, following the decision of the Hadassah Women's Organization to close the temporary hospital they had operated in Beer Sheba since 1948. The work at hand describes the ideological and political struggle between the two sides, the conflicting interests of the Government of Israel and the Labor Federation regarding the health needs of the city, and the factors that, in the end, led to the establishment of the hospital by the Federation's Clalit Sick Fund. The research is based on both archival material and on input from informants from the period who constitute primary sources.

    The U.S. scientific and medical teams sent to Cameroon by the Office of Foreign Disaster Assistance of the Agency for International Development (AID) to investigate the cause of the lethal gas release at Lake Nyos, Cameroon, have submitted their preliminary reports to the agency. While neither team could reach definitive conclusions without the opportunity to conduct laboratory analyses on their samples, they were able to make tentative statements about what may have occurred at the volcanic crater lake on the evening of August 21, 1986 (Eos, September 2, 1986, p. 659). At this early stage, it seems most likely that the gas release was triggered by a limnological phenomenon, such as an overturn of the lake, rather than by a sudden injection of volcanic gases. The origin of the gas seems most likely to be magmatic, but a biogenic origin has not been ruled out.

    To determine the prevalence of Pneumocystis pneumonia (PCP), a major opportunistic infection in AIDS patients in Europe and the USA, in Cameroon. Induced sputum samples from 237 patients without pulmonary symptoms (126 HIV-positive and 111 HIV-negative outpatients) treated at a regional hospital in Cameroon were examined for the prevalence of Pneumocystis jirovecii by specific nested polymerase chain reaction (nPCR) and staining methods. CD4 counts and the history of antiretroviral therapy of the subjects were obtained through the ESOPE database system. Seventy-five of 237 study participants (31.6%) were colonised with Pneumocystis, but none showed active PCP. The Pneumocystis colonisation rate in HIV-positive subjects was more than double that of HIV-negative subjects (42.9% vs. 18.9%, P < 0.001). In the HIV-positive group, the colonisation rate corresponds to the reduction in the CD4 lymphocyte counts. Subjects with CD4 counts >500 cells/μl were colonised at a rate of 20.0%, subjects with CD4 counts between 200 and 500 cells/μl of 42.5%, and subjects with CD4 counts <200 cells/μl of 57.1%. Colonisation with Pneumocystis in Cameroon seems to be comparable to rates found in Western Europe. Prophylactic and therapeutic measures against Pneumocystis should be taken into account in HIV care in western Africa. © 2014 John Wiley & Sons Ltd.

    Malaria is an endemic disease in Cameroon. Expatriate population is also affected by malaria risk. Many studies are published on malaria, but few are focused on the expatriate population. The objective was to describe epidemiological characteristics andmanagement ofmalaria at Plasmodium falciparum in Yaounde expatriate population. This is a retrospective analysis of all patients treated at health center of the French Embassy in Yaounde in 2013 with a diagnosis of malaria. 103 cases were recruited. Out of them, 32.7% came from the outskirts of Yaounde, 25.2% from the coastal area of Cameroon, and 20.4% from the center of Yaounde. 22 patients were hospitalized, including 6 in Emergency department. 3 deaths were reported during this period. Severe malaria cases are regularly detected in expatriate population inYaounde and preferentially patients, who are over 50 years old, long stay residents in Cameroon and they paid less attention on prevention and vector control. This study confirms the presence of urban malaria in Yaounde and the need to adopt measures including prophylaxis. To the ignorance of risk and the poor adherence to prophylactic measures, it appears important that the various embassies in northern countries have specific information to their expatriates living in endemic areas.

    This irritant blister dermatitis is caused by the genus Paederus whose geographical distribution is worldwide, with a higher incidence in tropical areas. It is induced by direct skin contact with pederin, a blistering and caustic substance found in the abdomen (coelome) of Paederus insects (insect order Coleoptera: family Staphylinidae). The diagnosis is based on the presence of typical clinical features combined with compatible epidemiological features. Our goal is to describe the epidemiological and clinical features of this irritant contact dermatitis in Cameroon through a retrospective study conducted at the end of the rainy season at the Oku Hospital in Northwest Cameroon and to also include cases reported at the medical center of the French Embassy in Yaounde during this same timeframe. In addition, we conducted a literature review of paederus dermatitis. Nineteen patients were included in this study. More than half of the patients presented with more than two lesions predominantly localized to the face or the neck; less than half had complications manifesting as either localized or respiratory reactions and three patients presented periorbital involvement. This study confirms the presence of paederus dermatitis in Cameroon. It is mainly localized in the unusual geoclimatic region of the western high mountains within the country, as well as the usual warm, moist areas of Yaounde. The clinical evolution of this dermatitis is usually one of spontaneous and uneventful resolution with complications being rare. Curative treatment is one of localized topical therapies while oral antibiotic therapy should be reserved for more complicated cases.

  7. Women's experiences of the abortion law in Cameroon: "What really matters".

    2010-05-01

    While prosecutions of women who have had an illegal abortion are rare in Cameroon, women who have a legitimate claim to a legal abortion, e.g. following rape, can rarely take advantage of it. This is because the law in Cameroon is not applied, either when it is violated or when it is indicated. This paper examines the histories of four young women who became pregnant and had an abortion in the Anglophone region of the Cameroon Grassfields. Three of them became pregnant following rape or sexual coercion, in one case by the girl's priest, in the second case by her employer's son, and in the third case by a stranger. The fourth young woman, who sold sex for survival money and food, had two abortions while in prison for committing infanticide following a failed attempt to abort an earlier pregnancy. The four young women were interviewed as part of a qualitative, hospital-based study among 65 women who had had abortions in 1996-97. The women's affecting personal histories illuminate the reality of living under a restrictive abortion law, the troubling conditions in which they have to manage their lives, and the harsh circumstances in which they become pregnant and seek (but may not find) a safe abortion.

    In Italy, the prevalence of smoking among health professionals is higher than in the general population and this might hamper their role in the promotion of health. This study aimed to investigate how the smoking status of healthcare professionals might influence knowledge, attitudes and clinical practice in a hospital in central Italy in order to enforce effective tobacco control measures. Physicians and professionals of the hospital were asked to complete an anonymous questionnaire which yielded epidemiological and environmental information on knowledge, attitude, clinical practice and quality of the hospital environments, in relation to smoking. Overall, among the employees of the hospital, the smoking prevalence was 47%, (42% among physicians and 43% among nurses); 30% admitted smoking in the hospital and three quarters of the smokers would like to quit. Some knowledge, opinions and attitudes differ statistically among the smoking categories. For example, only 35% of the smokers admitted that smoking is more dangerous to health than atmospheric and car pollution compared with 60% of the ex or never smokers (p=0.04). Fewer smokers realize that their behavior is seen as a role model by patients. A greater percentage of smokers state that patients (34%) and visitors (43%) often smoke in hospital and these percentages are significantly higher than those reported by ex or never smokers (p≤0.05). All smokers claim that they never smoke in patient rooms, infirmaries and clinics, whereas over 20% of ex or never smokers report that smoking sometimes occurs in these places (p=0.015). The mean concentration of PM 2.5 in the 25 rooms was 2.4 μg/m3 with a range from 1 to 7 μg/m3. This study implies that the prevalence of smoking among health professionals may be very high, and might be twice the rate observed in the general population. Generally, smokers report less knowledge compared with ex and never-smokers and it seems that they systematically underestimate the

    This paper analyzes the impact of oil revenues on the agriculture-based economy of Cameroon, a significant (100,000 barrels per day) but temporary (20 years' of reserves) oil producer. It has been observed in other oil exporting countries that when oil revenues are spent domestically, an appreciation of the real exchange rate results, leading to a shift in the production mix away from tradable sectors in favor of nontradables. Using a multisectoral, general equilibrium model of Cameroon, the authors show that while this effect occurs in the aggregate, some tradable sectors actually expand. In particular some import-substituting industries, because they produce output which is only imperfectly substitutables with foreign goods, undergo an increase in demand despite the real exchange rate appreciation. The traditional export sectors -- coffee and cocoa in Cameroon's case - do suffer, however, as a result of their decline in international competitiveness. Moreover, while real wages increase throughout the economy, the gap between rural and urban wages widens. Finally, efforts to protect the tradable sectors with tariffs have little effect on reversing the structural change induced by oil revenues.

    Objective. To establish the percentile charts of birth weights for gestational age and sex within the Cameroonian population. Methods. A review of medical records of infants born between January 2007 and December 2011 at the maternities of two hospitals in Cameroon, Central Africa. Multiple pregnancies, births of HIV infected women, stillbirths, and births with major fetal malformations were excluded. The smooth curves of birth weight for gestational age and sex were created using the Gamlss package under R.3.0.1 software. Results. The birth weights of 12837 live birth singleton infants born to HIV negative women between 28 and 42 weeks of gestation were analyzed to construct the birth weight curves for gestational age and sex. The smoothed percentile curves of birth weights for gestational age and sex of Cameroonian infants have demonstrated an increasing slope until 40 weeks and then a plateau. There was a varied difference of distribution in birth weights for gestational age between Cameroonian, Botswanan, American, and French infants. Conclusion. We established the reference curves of birth weights for gestational age and sex for Cameroonians. The difference in birth weight curves noted between Cameroonian, Botswanan, American, and French infants suggests the importance of establishing the regional birth weight norms.

    Hepatitis C virus infects humans world-wide. The virus genome varies greatly and it has several genotypes. HCV infection is highly prevalent in Central Africa and Cameroon. Initial studies on the genetic variability of HCV showed infection with HCV genotypes 1, 2, and 4. We have now sequenced the NS5b and E2 regions of 156 HCV isolates collected from patients presenting for diagnosis in Yaounde and used the data to describe the distribution of HCV genotypes and subtypes in patients with hepatitis in Cameroon. Genotype 1 was more frequent than Genotypes 4 and 2. Genotypes 1 and 4 were highly heterogeneous, containing many subtypes described previously (1b, 1c, 1e, 1h, 1l, 4f, 4t, 4p, 4k) and unsubtyped groups. There was a systematic phylogenetic concordance between NS5b and E2 sequence clustering. The Genotype 2 sequences did not vary. Neither subject age nor gender influenced HCV distribution. HCV Genotypes 1 and 4 are very heterogeneous in Cameroon, perhaps due to ancient infections. The homogeneity of HCV Genotype 2 indicates its more recent introduction from western Africa.

    The history of the genus Pan is a topic of enduring interest. Chimpanzees (Pan troglodytes) are often divided into subspecies, but the population structure and genetic history of chimpanzees across Africa remain unclear. Some population genetics studies have led to speculation that, until recently, this species constituted a single population with ongoing gene flow across its range, which resulted in a continuous gradient of allele frequencies. Chimpanzees, designated here as P. t. ellioti, occupy the Gulf of Guinea region that spans southern Nigeria and western Cameroon at the center of the distribution of this species. Remarkably, few studies have included individuals from this region, hindering the examination of chimpanzee population structure across Africa. Here, we analyzed microsatellite genotypes of 94 chimpanzees, including 32 designated as P. t. ellioti. We find that chimpanzees fall into three major populations: (i) Upper Guinea in western Africa (P. t. verus); (ii) the Gulf of Guinea region (P. t. ellioti); and (iii) equatorial Africa (P. t. troglodytes and P. t. schweinfurthii). Importantly, the Gulf of Guinea population is significantly different genetically from the others, sharing a last common ancestor with the populations in Upper Guinea ~0.46 million years ago (mya) and equatorial Africa ~0.32 mya. Equatorial chimpanzees are subdivided into up to three populations occupying southern Cameroon, central Africa, and eastern Africa, which may have constituted a single population until ~0.10–0.11 mya. Finally, occasional hybridization may be occurring between the Gulf of Guinea and southern Cameroon populations. PMID:21368170

    The origin of the volcanism in the Cameroon Volcanic Line and the nature of its mantle sources are still highly controversial. We present major and trace element compositions as well as Sr-Nd-Pb-Hf isotopic results on mafic and intermediate lavas from the Bafang area in the central part of the Cameroon Volcanic Line. The lavas range from basanites and basalts to hawaiites and mugearites with an alkaline affinity and were emplaced between 10 and 6 Ma ago. The evolution from basalts and basanites to more differentiated rocks involved fractionation of olivine, clinopyroxene and Fe-Ti oxides, but the isotopic compositions show that crustal contamination processes affected some magmas during their ascent in the crust. Basalts and basanites originated from a garnet-bearing mantle source and their differences are mostly due to variable degrees of partial melting. The isotopic composition of the uncontaminated samples imply the participation of three distinct mantle components, the depleted MORB mantle (not dominant), an enriched component and a Pb radiogenic component similar to the source of the Mount Cameroon. Combined with previously published isotopic data from the Cameroon Volcanic Line, our new results indicate that the source of the volcanism mostly reside in the lithospheric mantle and is different from what can be expected from the melting of a mantle accreted from or modified during the emplacement of the St. Helena mantle plume.

    Objective of this study was to systematically investigate the family histories of a large set of patients affected with Meniere's disease to determine the prevalence of familial MD and Meniere-like symptoms in their families. All 640 patients treated at the Oulu University Hospital and Kainuu Central Hospitals during 2005-2010 for Meniere's disease were selected as the initial study population. A postal family history survey was sent to all subjects. Hospital records of all patients were studied to confirm diagnosis and sufficient differential diagnosis. All patients that revealed a positive family history of Meniere's disease or Meniere-like symptoms were phone interviewed and the probability of Meniere's disease in a relative was estimated on a three level scale: probable, possible or unlikely. Affected family members of the patients were recruited to the study if possible. Familial Meniere's disease could be confirmed in 9.3% of patients, but 32.7% patients reported Meniere-like symptoms in their family. It was not possible to confirm all cases, but a family history of Meniere's disease was convincing (confirmed or probable) in 23.4% of the patients. Genetic factors are significant in the development of Meniere's disease.

    Toxoplasmosis is caused by an intracellular protozoan, Toxoplasma gondii, which has a wide geographical distribution. The congenital form results in a gestational form that can present a temporary parasiteamia that will infect the fetus. For this reason early diagnosis in pregnancy is highly desirable, allowing prompt intervention in cases of infection. The aim of this study was to determine the seroprevalence of Toxoplasma gondii antibodies among pregnant women attending the Douala General Hospital. The study was carried out between March and July 2009, whereby 110 pregnant women were tested for IgG and IgM antibodies and information about eating habits and hygienic conditions was collected using a questionnaire. These women's ages ranged from 20–44 years old with an average of 29.9 years; the overall IgG and IgM seroprevalence was 70% and 2.73 % respectively. Seroprevalence was significantly high amongst women who ate raw vegetables (76.39%, P<0.05) and there was a significant trend towards a higher seroprevalence in women who did not have a good source of water (75.58%, P<0.05). This research showed that consumption of raw vegetables and poor quality drinking water are two risk factors associated with Toxoplasma gondii infection amongst pregnant women attending the Douala General Hospital in Cameroon.

    To present an analysis of the Department of Paediatrics' statistics on hospital mortality, covering the period through 1980-1990. Basic information was recollected from logbooks of the Department's wards. Descriptive statistics are estimated on death and its main causes. The proportion of deaths in relation to total admissions and in relation to global in-hospital mortality are computed and their changes over time documented. The data show an important decrease of in-hospital global mortality in spite of the increase of the number of admissions over time. The pattern of the main causes of death changed, and the authors postulate that the change is attributed to a dramatic change in the epidemiological pattern of childhood morbidity in Maputo City, especially due to measles vaccination. In parallel, the study suggests an increase in the prevalence of severe malnutrition. Hospital statistics, while dependent on socio-economic conditions, can be significantly changed by Public Health interventions. Monitoring and analysing hospital statistics is important for documenting epidemiological changes, and also to suggest community interventions. From that point of view, epidemiological surveillance and hospital statistics are complementary.

  18. The Nature of the Cameroon Volcanic Line: Evidence from Seismic Anisotropy and Receiver Functions

    The Cameroon geological record spans more than 3 billion years, from Congo Craton basement formation during the Archean, to Cenozoic volcanism along the Cameroon Volcanic Line (CVL). Intriguingly, the CVL, which straddles the continent-ocean boundary in central West Africa, displays no age-progression along its length. Analogies with other hotspot chains worldwide are thus not well established. To help address this issue, we present a receiver function study of bulk crustal structure, and an SKS shear wave splitting study of seismic anisotropy using data from a recent broadband seismic experiment in Cameroon. Within the cratonic Cameroon, crustal Vp/Vs ratios show little variation between Archean and Proterozoic domains, perhaps indicating similar mechanisms of crustal formation during more than 2 billion years of the Precambrian. The edge of the Congo Craton, however, is characterized by an abrupt change in crustal thickness of ~5 km, which constrains the northern and western edges of the craton to be ~4N and ~10E respectively. Along the CVL, Vp/Vs ratios are low (~1.74) compared to other hotspots worldwide, providing no evidence for either partial melt, or mafic crustal intrusion due to Cenozoic volcanism. The anisotropy study indicates that fast polarisation directions parallel the trend of the Central African Sear Zone (CASZ), which developed during the breakup of the Pangea supercontinent during Cretaceous times. Beneath much of the CVL, however, we observe only null SKS splitting observations. The lack of lithospheric fabric here may be the result of it being destroyed during Cenozoic hotspot tectonism. However, there is no evidence for anisotropic aligned melt within the lithosphere, unlike hotspots such as Ethiopia, with the implication that neither a CASZ-related lithospheric fabric nor horizontally oriented asthenospheric fabrics exist beneath the line. This finding is in agreement with the receiver function study, and petrological studies that suggest

    Chronic suppurative otitis media (CSOM) is still a significant health problem in developing countries. Therefore, it was pertinent to determine the local Malawian microbiology in order to guide adequate treatment, avoid complications, and provide records for future reference. The study sought to determine the CSOM-causing microorganisms at Queen Elizabeth Central Hospital in Blantyre, Malawi, and establish their relationship signs and symptoms, and with the demographic pattern of the study. This was a hospital-based cross-sectional descriptive study carried out at the ENT outpatient clinic and the Microbiology Department of Queen Elizabeth Central Hospital.The sample comprised 104 patients with unilateral or bilateral active CSOM, who met the inclusion criteria. All patients were evaluated through a detailed history and clinical examination. Pus samples from draining ears were collected by aspiration with a sterile pipette. The specimens were immediately sent for microbiological analysis. Data were analyzed using SPSS.version 20. The study found that Proteus mirabilis, Pseudomonas aeruginosa, and Staphylococcus aureus were the most prevalent aerobic bacteria, while Bacteroides spp. and Peptostreptococcus spp. were the commonest anaerobic bacteria causing CSOM. These CSOM-causing microorganisms were predominant among males aged 18 years and below. Some CSOM-causing microorganisms were-significantly more so than the others-characteristically associated with each of the following clinical features: quantity of pus drainage, mode of onset, otalgia, hearing loss, location of tympanic membrane perforation, and mucosal appearance.

    The World Health Organization (WHO) recommends task-shifting HIV care to nurses in low-resource settings with limited numbers of physicians. However, the effect of such task-shifting on the health-related quality of life (HRQL) of people living with HIV (PLHIV) has seldom been evaluated. We aimed to investigate the effect of task-shifting HIV care to nurses on HRQL outcomes in PLHIV initiating antiretroviral therapy (ART) in rural district hospitals in Cameroon. Outcomes in PLHIV were longitudinally collected in the 2006-2010 Stratall trial. PLHIV were followed up for 24 months by nurses and/or physicians. Six HRQL dimensions were assessed during face-to-face interviews using the WHO Quality of Life (WHOQOL)-HIV BREF scale: physical health; psychological health; independence level; social relationships; environment; and spirituality/religion/personal beliefs. The degree of task-shifting was estimated using a consultant ratio (i.e. the ratio of nurse-led to physician-led visits). The effect of task-shifting and other potential correlates on HRQL dimensions was explored using a Heckman two-stage approach based on linear mixed models to adjust for the potential bias caused by missing data in the outcomes. Of 1424 visits in 440 PLHIV (70.5% female; median age 36 years; median CD4 count 188 cells/μL at enrolment), 423 (29.7%) were task-shifted to nurses. After multiple adjustment, task-shifting was associated with higher HRQL level for four dimensions: physical health [coefficient 0.7; 95% confidence interval (CI) 0.1-1.2; P = 0.01], psychological health (coefficient 0.5; 95% CI 0.0-1.0; P = 0.05), independence level (coefficient 0.6; 95% CI 0.1-1.1; P = 0.01) and environment (coefficient 0.6; 95% CI 0.1-1.0; P = 0.02). Task-shifting HIV care to nurses benefits the HRQL of PLHIV. Together with the previously demonstrated comparable clinical effectiveness of physician-based and nurse-based models of HIV care, our results support the WHO recommendation

    Fungal infections are common complication among hospitalized patients especially between who is immunocompromised. Wet cooling systems in the hospital environment play a critical role as a source of these infections. The aim of this study was survey of wet cooling system of hospitals for fungal contamination in Arak city. This study was conducted during May to September of 2016. Sampling was done as random. Samples were obtained from water and straw of 84 wet cooling systems of four hospitals in Arak city. Samples were cultured in Sabouraud dextrose agar medium contain of chloramphenicol. Identification of fungi was performed by Slide culture method. From 84 wet cooling systems, 32 (38.1%) were contaminated with fungi. The highest fungal contamination was found in wards of oncology and CCU. The most prevalent of fungi isolated in this study were Aspergillus spp. and Candida spp., respectively. The findings of this descriptive cross-sectional study clearly indicate, in wards of the hospital that used wet cooling systems, there was considerable fungal contamination, particularly Aspergillus contamination. These results highlight a clear need for greater attention to the use of non-aqueous or closed circulation cooling systems, especially where susceptible patients receive medical care.

    Motivation is an individual's degree of willingness to exert and maintain an effort towards organizational goals. This study assessed motivational status and factors affecting it among health professionals in public hospitals of West Shoa Zone, Oromia Region. Facility based cross-sectional survey was employed. All health professionals who served at least for 6 months in Ambo, Gedo and Gindeberet hospitals were included. Self-administered Likert scale type questionnaire was used. Data were analyzed using SPSS version 20. Mean motivation calculated as percentage of maximum scale score was used. Bivariate and multiple linear regression analyses were done to see the independent effects of explanatory variables. The overall motivation level of health professionals was 63.63%. Motivation level of health professionals varied among the hospitals. Gindeberet Hospital had lower motivation score as compared to Ambo Hospital (B = -0.54 and 95% CI; -0.08,-0.27). The mean motivation score of health professionals who got monthly financial benefit was significantly higher than those who did not (B = 0.71 and 95% CI; 0.32, 1.10). Environmental factors had higher impact on doctors' motivation compared to nurses' (B = 0.51 and 95% CI; 0.10, 0.92). Supervisor-related factors highly varied in motivation relative to other variables. Motivation of health professionals was affected by factors related to supervisor, financial benefits, job content and hospital location. Efforts should be made to provide financial benefits to health professionals as appropriate especially, to those who did not get any such benefits. Officially recognizing best performance is also suggested.

    OBJECTIVE: To determine differences in phenotype and treatment among hospitalized elderly and young patients with inflammatory bowel disease (IBD), and the utility of International Classification of Diseases, 10th Revision (ICD)-10 codes in hospital discharge abstracts in diagnosing IBD in elderly patients. METHODS: A large Canadian health region hospitalization discharge database was used to identify elderly (>65 years of age) and young (19 to 50 years of age) patients with IBD admitted between April 1, 2007 and March 31, 2012, and a random sample of elderly patients with other colonic conditions. Medical records were reviewed to confirm IBD diagnosis and extract clinical information. The characteristics of elderly versus young hospitalized IBD patients and accuracy of ICD-10 IBD discharge codes in the elderly were assessed. RESULTS: One hundred forty-three elderly and 82 young patients with an IBD discharge diagnosis, and 135 elderly patients with other gastrointestinal discharge diagnoses were included. Elderly IBD patients were less likely to have ileocolonic Crohn disease (21.4% versus 50.9%; P=0.001), more likely to be prescribed 5-aminosalicylates (61% versus 43%; P=0.04), and less likely to be prescribed biologics (6% versus 21%; P=0.016) or immunomodulators (21% versus 42%; P=0.01). The sensitivity, specificity and positive predictive value of a single ICD code for CD were 98%, 96% and 94%, respectively, and for ulcerative colitis (UC) were 98%, 92% and 70%, respectively. CONCLUSIONS: Treatment approaches in elderly patients were different than in younger IBD patients despite having disease sufficiently severe to require hospitalization. While less accurate in UC, a single ICD-10 IBD code was sufficient to identify elderly CD and UC hospitalized patients. PMID:25874650

    AIM: The article presents the current data on the sensitivity of the main 37 strains of eXtremaly Drugs Resistance (XDR) category to anti-pseudomonas drugs. MATERIAL AND METHODS: The strains were collected during the prospective multicenter study in large multidisciplinary hospitals of Central Kazakhstan. Susceptibility to antimicrobial drugs was carried out by disk method and the serial dilution method with the interpretation of the results according to EUCAST criteria. Detection of carbapenemases gene of VIM, IMP, NDM and GES classes was carried out by PCR method using the commercial kits. RESULTS: All identified carbapenemases were sorted to VIM class and accounted for 63.64%. Resistance to aminoglycoside drugs exceeded 80%. All the strains were susceptible to polymyxin. CONCLUSION: Thus, at the present stage the circulation of P. aeruginosa strains of XDR category continues in major hospitals in Kazakhstan. The strains remain sensitiveness only to polymyxin.

    The purpose of this study was to survey antibacterial resistance in outpatients of Chinese county hospitals. A total of 31 county hospitals were selected and samples continuously collected from August 2010 to August 2011. Drug sensitivity testing was conducted in a central laboratory. A total of 2946 unique isolates were collected, including 634 strains of Escherichia coli, 606 Klebsiella pneumoniae, 476 Staphylococcus aureus, 308 Streptococcus pneumoniae, and 160 Haemophilus influenzae. Extended-spectrum β-lactamases were detected in E. coli (42.3% strains), K. pneumoniae (31.7%), and Proteus mirabilis (39.0%). Ciprofloxacin-resistance was detected in 51.0% of E. coli strains. Salmonella spp. and Shigella spp. were sensitive to most antibacterial agents. Less than 8.0% of Pseudomonas aeruginosa isolates were resistant to carbapenem. For S. aureus strains, 15.3% were resistant to methicillin, and some strains of S. pneumoniae showed resistance to penicillin (1.6%), ceftriaxone (13.0%), and erythromycin (96.4%). β-lactamase was produced by 96.5% of Moraxella catarrhalis strains, and 36.2% of H. influenzae isolates were resistant to ampicillin. Azithromycin-resistant H. influenzae, imipenem-resistant but meropenem-sensitive Proteus, and ceftriaxone- and carbapenem non-sensitive M. catarrhalis were recorded. In conclusion, cephalosporin- and quinolone-resistant strains of E. coli and Klebsiella pneumonia and macrolide-resistant Gram-positive cocci were relatively prominent in county hospitals. The antibacterial resistance profiles of isolates from different geographical locations varied significantly, with proportions in county hospitals lower than those in their tertiary counterparts in the central cities, although the difference is diminishing.

    Background and purpose — The burden of road traffic injuries globally is rising rapidly, and has a huge effect on health systems and development in low- and middle-income countries. Malawi is a small low-income country in southeastern Africa with a population of 16.7 million and a gross national income per capita of only 250 USD. The impact of the rising burden of trauma is very apparent to healthcare workers on the ground, but there are very few data showing this development. Patients and methods — The annual number of femoral fracture patients admitted to Kamuzu Central Hospital (KCH) in the Capital of Malawi, Lilongwe, from 2009 to 2014 was retrieved from the KCH trauma database. Linear regression curve estimation was used to project the growth in the burden of femoral fractures and the number of operations performed for femoral fractures over the same time period. Results — 992 patients with femoral fractures (26% of all admissions for fractures) presented at KCH from 2009 through 2014. In this period, there was a 132% increase in the annual number of femoral fractures admitted to KCH. In the same time period, the total number of operations more than doubled, but there was no increase in the number of operations performed for femoral fractures. Overall, there was a 7% mortality rate for patients with femoral fractures. Interpretation — The burden of femoral fractures in Malawi is rising rapidly, and the surgical resources available cannot keep up with this development. Limited funds for orthopedic trauma care in Malawi should be invested in central training hospitals, to develop a sustainable number of orthopedic surgeons and improve current infrastructure and equipment. The centralization of orthopedic surgical care delivery at the central training hospitals will lead to better access to surgical care and early return of patients to local district hospitals for rehabilitation, thus increasing surgical throughput and efficiency in a more cost

    To further investigate the genetic diversity of hepatitis B virus (HBV) genotype A in Africa, we analysed 263 HBV strains from Nigeria (n=163) and Cameroon (n=100). Phylogenetic analysis of S fragment sequences attributed 175 strains (66.5%) to genotype E and 88 (33.5%) to genotype A. In Cameroon, genotype A strains were the most prevalent (79/100, 79.0%), whereas, in Nigeria, genotype E was highly dominant (154/163, 94.5%). The genotype A strains grouped with reference strains of subgenotype A3 (n=8), the provisional subgenotype A5 (n=43), a recently reported new variant from Rwanda (n=35), or as outliers (n=2). Ten complete genome sequences obtained from strains that clustered with the new variant from Rwanda formed a separate group supported by a bootstrap value of 96. The between-group distance to other potential or recognized subgenotypes of genotype A was at least 3.81%. Thus, the new group of strains could be considered as a new subgenotype of HBV genotype A, tentatively named 'A7'. Interestingly, the 'A7' strains from Rwanda and Cameroon showed an interspersed clustering, but essentially no other (sub)genotypes were shared between the two countries, suggesting that 'A7' may have evolved in a yet unknown place and may have only relatively recently spread to Rwanda and Western Cameroon. Strains attributed to provisional subgenotype A5 were found for the first time in Cameroon (n=36) and Central Nigeria (n=2), indicating that A5 is more widespread than previously thought.

  11. Late Cretaceous intraplate silicic volcanism in the Lake Chad region: incipient continental rift volcanism vs. Cameroon Line volcanism

    The crustal evolution of west-central Africa during the Cretaceous was directly related to plate motion associated with the opening of the central Atlantic Ocean. Late Cretaceous (~66 Ma) to recent magmatism related to the Cameroon Line stretches from Northern Cameroon (i.e. Golda Zuelva) to the Gulf of Guinea (i.e. Pagalu) and is considered to be due to mantle-crust interaction. The volcanic rocks at Hadjer el Khamis, west-central Chad, are considered to be amongst the oldest volcanic rocks of the Cameroon Line but their relationship is uncertain because they erupted during a period of a regional extension associated with the opening of the Late Cretaceous (~75 Ma) Termit basin. The silicic volcanic rocks can be divided into a peraluminous group and a peralkaline group with both rock types having similar chemical characteristics as within-plate granitoids. In situ U/Pb zircon dating yielded a mean 206Pb/238U age of 74.4 ± 1.3 Ma and indicates the rocks erupted ~10 million years before the next oldest eruption attributed to the Cameroon Line. The Sr isotopes (i.e. ISr = 0.7050 to 0.7143) show a wide range but the Nd isotopes (i.e. 143Nd/144Ndi = 0.51268 to 0.51271) are more uniform and indicate that the rocks were derived from a moderately depleted mantle source. Major and trace elemental modeling show that the silicic rocks likely formed by shallow fractionation of a mafic parental magma where the peraluminous rocks experienced crustal contamination and the peralkaline rocks did not. The silicic rocks are more isotopically similar to Late Cretaceous basalts in the Doba and Bongor basins (i.e. ISr = 0.7040 to 0.7060; 143Nd/144Ndi = 0.51267 to 0.51277) of southern Chad than to rocks of the Cameroon Line (i.e. ISr = 0.7026 to 0.7038; 143Nd/144Ndi = 0.51270 to 0.51300). Given the age and isotopic compositions, it is likely that the silicic volcanic rocks of the Lake Chad area are related to Late Cretaceous extensional tectonics rather than to Cameroon Line magmatism.

    Travelers to West Central Africa are at risk for infection with Onchocerca volvulus. We describe the case of an adventurous traveler who became infected with O volvulus after a 10-day stay in rural Cameroon. Two years after his return, he was diagnosed with a 3-month history of limb swelling with pruritus and fixed edema of the right arm. He was successfully treated by a single dose of ivermectin, with an additional treatment with doxycycline. The patient was followed-up during 1 year after therapy without relapse. Such travelers experiencing unusual dermatitis syndromes should prompt evaluation for onchocerciasis.

    In Japan, many problems related to alcohol are pointed out from before. We believe that there is a unique drinking culture in Okinawa, such as a large amount of alcohol. Therefore, we estimate many people in Okinawa have a drinking problem. We conducted a survey of patients who visited general hospital (medical or surgical or orthopedic) in 2007. The purpose of this study is to collect basic data for introducing alcoholics to specialized treatment as early as possible, detecting the person who drink large amounts of alcohol, performing early intervention for people who drink large amount of alcohol, and advancing cooperation with specialized medical agencies of alcohol. As a result, Among the patients who visited general hospital in Okinawa, many problem drinkers are concentrated in the young age. and they have strong fears of health. The possibility of early intervention with intervention techniques, such as brief intervention, has been suggested.

    The cost of blood and blood products has increased rapidly over the last several years while the supply of available blood donors has simultaneously decreased. Higher blood costs and donor shortages have put a strain on the relationship between blood suppliers and their hospital customers. This study examines the association between blood center centralization or decentralization and several aspects of hospital satisfaction. Centralized and decentralized blood centers have significant differences in various aspects of hospital customer satisfaction. Advantages and disadvantages of the two structures are discussed, as well as areas for future research.

    To determinate the significance of risk factors with the presence of biofilm on catheters of patients attended at tertiary hospital cares. A total of 126 patients were included, data collection by observing the handling of the CVC, clinical history and microbiological isolation methods of CVCs tips (Roll-plate, sonication and scanning electron microscopy) were evaluated. Certain factors, such as the lack of proper hand washing, the use of primary barriers and preparing medications in the same hospital service, showed an important relationship between biofilm formation in CVCs. The sonication method presented that most of the samples had isolation of multispecies 29 samples (64%); in contrast with the roll-plate method, just one sample (3%) was isolated. The importance of the strict aseptic techniques of insertion and of the handlings of CVC was highlighted, the failure of both techniques was related to the biofilm formation and was evidenced using the scanning electron microscopy. Since this tool is not available in most hospitals, we present the correlation of those evidences with other standard microbiological methods and risk factors, which are necessary for the sensible detection of the different steps of the biofilm formation on CVC and their correct interpretation with clinical evidences.

    To determine the accuracy, turnaround time and cost effectiveness of bedside monitoring of blood glucose levels by non-laboratory health care workers and centralized testing of blood glucose by automated analyzer in a tertiary care hospital. The study was conducted in Section of Chemical Pathology, Department of Pathology and Microbiology and Section of Endocrinology Department of Medicine, Aga Khan University and Hospital Karachi, from April 2005 to March 2006. One hundred and ten patients were included in the study. The blood glucose levels were analyzed on glucometer (Precision Abbott) by finger stick, using Biosensor Technology. At the same time venous blood was obtained to analyze glucose in clinical laboratory on automated analyzer (SYNCHRON CX7) by glucose oxidase method. We observed good correlation between bed side glucometer and laboratory automated analyzer for glucose values between 3.3 mmol/L (60 mg/dl) and 16.7 (300 mg/dl). A significant difference was observed for glucose values less than 3.3 mmol/L (p = 0.002) and glucose values more than 16.67 mmol/l (p = 0.049). Mean Turnaround time for glucometer and automated analyzer were 0.08 hours and 2.49 hours respectively. The cost of glucose testing with glucometer was 48.8% lower than centralized lab based testing. Bedside glucometer testing, though less expensive does not have good accuracy in acutely ill patient with either very high or very low blood glucose levels.

    Background: The study was conducted to evaluate the knowledge, attitudes and practices of breast-feeding in the West region of Cameroon. Methods: A cross sectional descriptive study was conducted in two health facilities on 195 mother-infant pairs, seen at the out patient and vaccination units of the Bafoussam Regional Hospital over a period of one month from 1st to 30th September 2008. The socio-demographic characteristics of mothers, knowledge on breastfeeding and the practice of breastfeeding were studied. Data was analyzed using the SPSS software. The chi square and student t- test were used for comparison and results considered significant for P< 0.05. Results: Breastfeeding was practised by 99.48% of the mothers. Only 33.8% of the mothers knew that they had to exclusively breastfeed up to 6 months, and 20% effectively breastfed up to 6 months. The mean duration of breastfeeding was 5.06 months and negatively correlated with the number of children and the profession of the mother. In 69.74% of the women, nothing was given to the baby before the first breastfeed. Discontinuation of breastfeeding was done averagely around 15.24 months and earlier in married women and in those with a higher educational level. Conclusion: Although the majority of parents practised breast feeding, only a minority understood its benefits, so more should be done to educate the community on the benefits of exclusive breast-feeding for up to six months.

    Movement of live animals is a major risk factor for the spread of livestock diseases and zoonotic infections. Understanding contact patterns is key to informing cost-effective surveillance and control strategies. In West and Central Africa some of the most rapid urbanization globally is expected to increase the demand for animal-source foods and the need for safer and more efficient animal production. Livestock trading points represent a strategic contact node in the dissemination of multiple pathogens. From October 2014 to May 2015 official transaction records were collected and a questionnaire-based survey was carried out in cattle markets throughout Western and Central-Northern Cameroon. The data were used to analyse the cattle trade network including a total of 127 livestock markets within Cameroon and five neighboring countries. This study explores for the first time the influence of animal trade on infectious disease spread in the region. The investigations showed that national borders do not present a barrier against pathogen dissemination and that non-neighbouring countries are epidemiologically connected, highlighting the importance of a regional approach to disease surveillance, prevention and control. Furthermore, these findings provide evidence for the benefit of strategic risk-based approaches for disease monitoring, surveillance and control, as well as for communication and training purposes through targeting key regions, highly connected livestock markets and central trading links.

    With a recently established Haemophilia Treatment Centre (HTC) in Yaoundé, Cameroon, over a hundred people living with haemophilia have been recruited and followed up at this centre. This study aimed at assessing the quality of haemophilia care provided at the HTC, in order to monitor and improve patient care. In February 2014, the HTC was assessed using recommended markers. Although few, the logistics and reagents for the diagnosis and treatment of haemophilia were available. There were seven trained workers involved with haemophilia care, but the multidisciplinary care team was incomplete. A total of 113 people living with haemophilia (all males) had been registered and regularly followed up at the HTC. This study showed that the HTC of the Yaoundé University Teaching Hospital, although not yet ideal, allows for some degree of haemophilia patient care. Hence, it may be recommended to improve the centre and make it fully established in Cameroon.

    As part of a national accelerated campaign to eliminate measles, we conducted a study, to define the epidemiology of measles in the Central Region. A descriptive survey was carried out on retrospective cases of measles. Patients were drawn from the three district hospitals (Assin, Asikuma and Winneba Hospitals) with the highest number of reported cases in the region. Records of outpatient and inpatient measles patients attending the selected health facilities between 1996 and 2000. Data on reported measles cases in all health facilities in the three study, districts were also analysed. The distribution of measles cases in person (age and sex), time (weekly, or monthly, trends) and place (residence), the relative frequency, of cases, and the outcome of treatment. There was an overall decline in reported cases of measles between 1996 and 2000 both in absolute terms and relative to other diseases. Females constituted 48%-52% of the reported 1508 cases in the hospitals. The median age of patients was 36 months. Eleven percent of cases were aged under nine months; 66% under five years and 96% under 15 years. With some minor variations between districts, the highest and lowest transmission occurred in March and September respectively. Within hospitals, there were sporadic outbreaks with up to 34 weekly cases. In Ghana, children aged nine months to 14 years could be appropriately targeted for supplementary, measles immunization campaigns. The best period for the campaigns is during the low transmission months of August to October. Retrospective surveillance can expediently inform decisions about the timing and target age groups for such campaigns.

  4. Mount Cameroon Eruptions, Related Hazards and Effects on the Ecosystem

    Mount Cameroon (MC) is the highest peak in West and Central Africa. It is the only active volcano along the 1600km, Cameroon volcanic line with NE-SW orientation. It has a height of about 4100m above sea level, is a typical example of a hazardous volcano in a densely populated area, often causing damage by lava flows. It shows layered mafic volcanic sequence thought to be related to near-continuous eruptions within the last century during which period it has erupted 8 times in 1909, 1922, 1925, 1954, 1959, 1982, 1999 and 2000. These volcanic activities are suggested to be contributing factor to the many small-scale shallow landslides within the last 20 years which have resulted in the loss of about 30 lives and significant damage to farmland and property. The relatively high carbon dioxide (CO2) content in MC Glass inclusions support the interpretation that the CO2 gas responsible for the 1984 Lakes Monoun and 1986 Nyos disasters is magmatic in origin, which killed 37 and over 1800 people respectively. Months before the latest 2000 eruption, MC was characterized by a seismic swarm recorded in 03/2000 by analogue seismic stations. The co-eruptive period from May 28th to June 19th, 2000 was characterized by sequences of earth quakes, swarms and volcanic tremor. The main shock had a magnitude 3.2 event and a modified Mercalli intensity of 3 to 4. The largest seismic event recorded had a magnitude of 4. An explosion on 5th June, 2000, injured many members of a surveillance team, and a helicopter crash on 10th June, 2000 killed both pilots. It also led to lava flow across the Limbe-Idenau highway, damage of forest and palm plantations in Bakingili, and the evacuation of the 600 inhabitants of Bakingili. Never the less MC has positive impacts on the environment such as increased soil fertility where agro-industrial plantations have taken advantage, and more touristic sites have developed. After the last eruption of 2000, a number of seismographs have been placed along

    This is the first study of particulate matter (PM) air pollution in Cameroon. In this study, mass concentration and PM size fractions as well as carbonaceous contribution to PM are measured in Bafoussam, Bamenda, and Yaoundé, Cameroon. Average concentrations in Bafoussam, Bamenda, and Yaoundé of PM2.5 are 67 ± 14, 132 ± 64, and 49 ± 12 μg/m3 and PM10 are 105 ± 29, 141 ± 107, and 65 ± 21 μg/m3, respectively. Daytime levels of PM2.5 and PM10 are seen to be higher than nighttime levels in all cities except Bamenda where nighttime levels are higher for both PM sizes. In Bafoussam, the average PM1.0 particle number concentration during the day is 19,800 pt/cc and during the evening is 15,200 pt/cc. PM2.5/PM10 mass ratios are 0.65 ± 0.05, 0.75 ± 0.05, and 0.78 ± 0.09 for Bafoussam, Bamenda, and Yaounde, respectively. Elemental carbon (EC) and organic carbon (OC) contribution to PM2.5 in Bafoussam, Bamenda, and Yaoundé are 3.9%, 2.9% and 12% for EC and 17.7%, 23.6%, and 34.2% for OC, respectively. After conducting spatial variability of PM mass concentration and size fractionation sampling at various locations within each of the three cities, we find that PM2.5 averages are highest during commercial meal preparation in Bafoussam (684 ± 546 μg/m3), and on the road in Bamenda (417 ± 113 μg/m3) and Yaoundé (110 ± 57 μg/m3). Additional air quality research in Central and West Africa is necessary to begin implementing policy steps that influence change and to advocate for improved health conditions in this rapidly expanding region of the world.

  6. Socio-cultural determinants of infant malnutrition in Cameroon.

    This study seeks to explore and explain the socio-cultural factors responsible for the incidence of infant malnutrition in Cameroon with particular emphasis on northern Cameroon where it is most accentuated. It combines quantitative data drawn from the 1991, 1998, 2004 and 2011 Cameroon Demographic and Health Surveys, as well as a literature review of publications by the WHO and UNICEF. This is further complemented with qualitative data from various regions of Cameroon, partly from a national ethnographic study on the ethno-medical causes of infertility in Cameroon conducted between 1999 and 2000. Whereas socio-cultural factors related to child feeding and maternal health (breast-feeding, food taboos and representations of the colostrum as dangerous for infants) are widespread throughout Cameroon, poverty-related factors (lack of education for mothers, natural disaster, unprecedented influx of refugees, inaccessibility and inequity in the distribution of health care services) are pervasive in northern Cameroon. This conjunction of factors accounts for the higher incidence of infant malnutrition and mortality in northern Cameroon. The study suggests the need for women's empowerment and for health care personnel in transcultural situations to understand local cultural beliefs, practices and sentiments before initiating change efforts in infant feeding practices and maternal health. Biomedical services should be tailored to the social and cultural needs of the target population--particularly women--since beliefs and practices underpin therapeutic recourse. Whereas infant diarrhoea might be believed to be the result of sexual contact, in reality, it is caused by unhygienic conditions. Similarly, weaning foods aimed at transmitting ethnic identity might not meet a child's age-specific food needs and might instead give rise to malnutrition.

    Ethnobotanical investigations were conducted in Fundong Central Subdivision in the Northwest Region of Cameroon to identify trees growing in the area and collect information on their uses by the local people. This research covered a period of 12 months from May 2007 to April 2008. Ethnobotanical information was collected through the show-and-tell/semi-structured method and personal interviews during field trips. Three villages were investigated. A total of 82 tree species were identified belonging to 70 genera and 42 families. Among these species, 40 were widely used by the local people in traditional medicine to treat 48 human ailments. Tree species were also used for fuel wood, construction materials, wood carving and honey production. Leaves and barks were commonly used in traditional medicine while the wood, branches and the entire plants were commonly used for other purposes. In spite of the scarcity of natural forests in the study area, the local populations continue to depend on indigenous and exotic trees in their surroundings for their survival. There is therefore need for cultivation, protection and sustainable management of these valuable resources for rural livelihoods. PMID:19555468

    Carbon dioxide was blamed for the deaths of around 1700 people in Cameroon, west Africa, in 1986 when a massive release of gas occurred from Lake Nyos, a volcanic crater lake. The clinical findings in 845 survivors seen at or admitted to hospital were compatible with exposure to an asphyxiant gas. Rescuers noted cutaneous erythema and bullae on an unknown proportion of corpses and 161 (19%) survivors treated in hospital; though these lesions were initially believed to be burns from acidic gases, further investigation suggested that they were associated with coma states caused by exposure to carbon dioxide in air. The disaster at Lake Nyos and a similar event at Lake Monoun, Cameroon, two years previously provide new information on the possible medical effects of large scale emissions of carbon dioxide, though the presence of other toxic factors in these gas releases cannot be excluded.

    While communicable diseases are the leading causes of morbidity and mortality in Malawi, the contribution of nosocomial or hospital-acquired infections (HAIs) is unknown but could be substantial. The single most important method of preventing nosocomial infections is hand hygiene. We report a study which was conducted in 2011 to investigate adherence to hand hygiene protocols by clinicians and medical students working at Queen Elizabeth Central Hospital in Blantyre, Malawi. There were two parts to the study: a single blinded arm in which participants were observed without their knowledge by trained nurses; and a second arm which included self-completion of questionnaire after participant consent was obtained. The 2009 World Health Organization hand hygiene technique and recommendations which were adopted by Queen Elizabeth Central Hospital were used to define an opportunity for hand washing and effectiveness of hand washing. Hand hygiene effectiveness was defined as adherence to at least 6 out of 7 steps (80%) of the hand hygiene technique when using alcohol-based formulation or at least 8 out of 10 steps (80%) of the hand hygiene technique when using water and soap formulation before and after having direct contact with patients or their immediate surroundings. Clinicians were found to have disinfected their hands more than medical students (p<0.05) but effectiveness was similar and very low between the two groups (p=0.2). No association was also found between having a personal hand sanitizer and hand hygiene practice (p=0.3). Adherence to hand hygiene was found to be 23%. Most of the participants mentioned infection transmission prevention as a reason for disinfecting their hands. Other reasons mentioned included: a routine personal hand hygiene behaviour and discomfort if not washing hands. The top three reasons why they did not disinfect hands were forgetfulness, unavailability of sanitizers and negligence. Adherence to hand hygiene practice was found to be low

    Fifteen pediatric cases of suspected Japanese encephalitis (JE) were reported in Beijing Children's Hospital during the late summer of 2013. The clinical manifestations in most cases included high fever, seizures, and abnormal magnetic resonance imaging findings. Twelve of 15 cases were laboratory-confirmed as JE cases by pathogen identification. Epidemiological investigations showed that five of the 12 laboratory-confirmed patients had an incomplete JE vaccination history. Follow-up investigations after discharge indicated that seven laboratory-confirmed JE patients without JE vaccinations had relatively poor prognoses, with an average Modified Rankin Scale (MRS) score of 2.6 when compared with the other five laboratory-confirmed, JE-vaccinated patients with an average MRS score of 0.5. The observation of pediatric JE cases among those with a history of JE vaccination warrants further attention. Copyright © 2016 The Editorial Board of Biomedical and Environmental Sciences.

    Background: Motorcycle-related injuries lead to considerable morbidity and mortality. The aim of this study is to determine the pattern and outcome of motorcycle-related injuries at Benue State University Teaching Hospital, Makurdi, Nigeria. Patients and Methods: Case records of all patients who presented to the accident and emergency department with motorcycle-related injuries between July 2012 and June 2013 were analysed for age, gender, injury host status (i.e. rider, pillion or pedestrian), nature of collision (motorcycle versus other vehicles, motorcycle versus motorcycle, motorcycle versus pedestrian or lone riders), body region injured, injury severity score (ISS) at arrival, length of hospital stay (LOS) and mortality. Results: Seventy - nine patients with motorcycle-related injuries were included in the study. They consisted of 63 males (61.8%) and 16 females (15.7%). The age range was 5-65 years with a mean of 32.4 ± 14.0. Motorcycle versus vehicle collisions were the most common mechanism of injury (n = 46, 58.2%). Musculoskeletal injuries constituted the most common injuries sustained (n = 50, 47.6%) and the tibia was the most frequently fractured bone (n = 14, 35.9%). The majority of patients (57.0%) sustained mild/moderate injuries (ISS ≤ 15). There was no statistically significant difference between the sexes for sustaining mild/moderate injuries or severe/profound injuries (P > 0.05). Mortality rate was 6.3% with head injuries being involved in all cases. Conclusion: Young males were mostly injured in motorcycle-related trauma. Musculoskeletal injuries were the most common injuries sustained and head injuries were involved in all the deaths. Enforcement of motorcycle crash bars and helmet usage is recommended.

    Background: Unintended pregnancy is a pregnancy that is either unwanted or mistimed. The objectives of this study were to determine the prevalence of unintended pregnancy as well as to document the determinant factors among pregnant women attending antenatal clinic at the University of Abuja Teaching Hospital, Gwagwalada, Abuja, Nigeria. Materials and Methods: This was a descriptive, cross-sectional study of 300 women attending the antenatal clinic of the Teaching Hospital. Information on sociodemographic characteristics, desirability of the current pregnancy at the time of conception, and knowledge and practice of contraceptive methods were collected using a pretested questionnaire. The data obtained were analyzed using SPSS version 20. Chi-square test was used for tests of associations with the level of significance set at P < 0.05. Results: The average age of the respondents was 30.0 ± 4.7 years. Overall, 33.3% and 58.3% of the respondents attained secondary and tertiary levels of education, respectively. The prevalence rate of unintended pregnancy was 16%. Contraceptive awareness was quite high (259, 86.3%). However, contraceptive usage was low as 192 (61.9%) had never used any form of contraceptives. Univariate analysis using Chi-square test showed a statistically significant association between age and unwanted pregnancy (χ2 = 68.56, P < 0.001), as well as between parity and unwanted pregnancy (χ2 = 39.92, P < 0.001). Conclusion: The prevalence of unintended pregnancy among women attending antenatal clinic is high, possibly due to low contraceptive usage. Adequate information, education, and communication materials should be provided during antenatal health talks. Advocacy visits for community sensitization should also be increased. PMID:27942101

    2014-07-01

    A structured questionnaire was administered to 50 medical patients, 50 surgical patients and 50 staff members at Vila Central Hospital, Vanuatu. A similar study was conducted 10 years earlier. In the intervening decade, Vanuatu has seen unprecedented population growth, increasing expatriate numbers, and the introduction of mobile phone and Internet networks. Given these social transformations, this study aimed to identify changes in custom medicine use over this period. Fifty-nine percent of interviewees had used custom medicine at least once, compared to 86% reported in the 2003 study. Thirty-two percent had used custom medicine in the last 12 months, a significant decline from 60% in the previous study. Collectively, rates of custom medicine use have declined but especially in the physical therapies such as bone setting. We believe this declining custom medicine use reflects an overall weakening traditional culture within Vanuatu and believe that within a generation, custom medicine knowledge will likely be lost.

    Nonmalarial acute undifferentiated fever (NMAUF) refers to a febrile illness with no indication of an organ-specific disease after diagnosis of malaria has been excluded. In developing countries, the empirical treatment of NMAUFs with antimalarial drugs continues even in the era of highly specific rapid diagnostic tests (RDTs) for malaria. We carried out a retrospective review of patients with fever admitted to a rural teaching hospital in central India. We categorized patients with NMAUF into different clinical syndromes and determined their demographic profile, inhospital course, and the pattern of antimalarial use. The study sample included 1,197 adult patients who were investigated for malaria; 1,053 (88%) of them had NMAUF, and use of further diagnostics in this group was limited. Despite one or more negative tests for malaria, many patients (39.9%, 95% CI 37.0-43.3) received antimalarial drugs. These results suggest a need for guidelines and training to improve empirical treatment of NMAUF.

    Background Ectopic pregnancy contributes to maternal morbidity and mortality, especially in low-resourced countries with limited facilities for early diagnosis and treatment. It is a very challenging condition to diagnose. Patients may collapse and die while undergoing investigation. Aims To assess surgical treatment given to patients presenting at Mpilo Central Hospital, the challenges that are faced and the outcomes; and also to document how women survive this dangerous condition in a setting challenged by low resources. Results All the patients had prompt life-saving surgery within 48 h of admission despite the challenges faced. The survival rate was 100% during the period of the study. Conclusion It is possible to prevent maternal mortality in low-resource countries by maintaining basic clinical and surgical skills.

    Two new cases of sarcoidosis are reported from Cameroon. The first one concerned a man, 53 years old, who presented multiple dermal nodules of the face, polyadenopathy , splenomegaly, exertional dyspnea, reticular and micronodular aspect of lungs X-ray. Diagnosis was confirmed by histology of skin, ganglions and bronchus biopsies. Patient was treated by corticotherapy. The other one concerned a woman, 28 years old, who presented successively mediastinal adenopathies, then, 9 months later, reticular and micronodular aspect of lungs X-ray. During this period, a treatment against tuberculosis had been established. Bronchus biopsies confirmed the diagnosis. The patient was also treated by corticosteroids. The authors wonder whether sarcoidosis is actually or apparently rare in Negro-Africans, owing to the fact of frequent failure to recognize this affection, or confusion with tuberculosis. Correct incidence of sarcoidosis in Negro-Africans should be defined.

    The viral C hepatitis is a disease which is often asymptomatic but with a very high risk of death. A prospective survey on multitransfused patients with a high transfusional risk has been conducted between May 1st and September 30th, 2001 in the medical services of the Hospital of Brazzaville. It deals with 252 samples of blood taken on 132 multitransfused patients and 120 control cases who have never been transfused. The screening of antibodies has been performed with ELISA technique by using 2 sensitive tests: the monolisa anti-HCV plus version 2 (Bio-Rad) and BIOTEC HCV a.b. Only monolisa is registered by AFSSAPS. The survey shows a overall seroprevalence of 13.9%: multitransfused patients: 26 out of 132 (19.7%) and control cases 9 out of 120 (7.5%). The prevalence of anti-HCV antibodies is practically similar in both series. It is low among control cases before 20 years old, but important in this same group when the patients are multitransfused. It is very significant among adult control cases, indicating the probability of other transmission modes in this age bracket. Patients suffering from hemoglobinopathy (sickle cell) and from malignant hemopathy paid an heavy toll to the virus with respectively 16.9% and 22% of prevalence even if the sampling is restricted. This results point out the necessary implementation of a systematic screening of all the main viruses before transfusion.

    The authors had for aim, to determine the frequency and the main clinical forms of severe malaria and to evaluate its management. A cross-sectional investigation was made in the "Complexe Pediatrique" of Bangui, the only children hospital of the CAR capital, from 12 January to 12 September 1998. The survey included children 6 months to 15 years of age presenting on admission with a positive thick drop examination, and at least one of the clinical symptoms of severe malaria as defined by the World Organization of Health (WHO). Four hundred and thirty-two children were included. Those from 6 months to 4 years of age accounted for 89.35% of the studied population. The most frequent clinical forms were neurological 31% and anemic 22.2%; the other forms were combined in 42.8%. Managing patients consisted of an etiologic treatment by quinine (91.7%) or sulfadoxine pyrimethamine (3.2%) and symptomatic treatment in the following proportions: rehydration: 49.3%; blood transfusion: 36.3%; preventing seizure: 72.9%; oxygen therapy: 77.5%; use of antipyretics: 96.7%, and correction of hypoglycemia: 9%. The death rate remained high with 62 deaths (14.35%). It was higher in combined forms (48 deaths out of 62). Severe malaria and its various clinical forms remain a major problem for our pediatric intensive care unit. Updated technical means and human resources could improve the management of severe pediatric malaria.

    Objectives: To investigate the epidemiology of pediatric hand fractures and to provide recommendations regarding prevention. Methods: Medical records and x-rays were retrospectively reviewed for age at the time of injury, gender, fracture pattern, place where the injury occurred, and mechanism of injury. The study was conducted at King Khalid University Hospital, Riyadh, Saudi Arabia between January 2005 and December 2011. Results: Of 361 cases reviewed, there were 291 (80.6%) male and 70 (19.4%) female patients. Most (46.2%) were in the age group of 13-18 years. For age group 1-4 years, the most common place of occurrence was at home (81.3%) and for the group 13-18 years, outdoors was the place of occurrence (64.7%). Females were mostly injured at home while males had similar distribution of indoor and outdoor injuries. The most common causes of fractures were: door slams in the 1-8 years age group; falls at home, in the 9-12 years age group; and both falls at home and sports in the oldest age group (13-18 years). The little finger ray are the most frequently injured part of the hand followed by the middle finger. Conclusion: Our series showed that most hand fractures in children occurred at home, which requires reevaluation of home settings. Implementation of safety measures during sports activities are relevant in the oldest age group. PMID:25935180

    Economic analysis plays a pivotal role in the management of medical store. The main objectives of this study were to consider always better control-vital, essential and desirable (ABC-VED) analysis with economic order quantity (EOQ), comparison of indexed cost and the actual cost, and to assess the expenditure for the forthcoming years. Based on cost and criticality, a matrix of nine groups by combining ABC and VED analysis was formulated. Drug categories were narrowed down for prioritization to direct supervisory monitoring. The subgroups AE and AV of the categories category I and II should be ordered based on EOQ. The difference between the actual annual drug expenditure (ADE) and the derived indexed cost using the cost inflation index (CII) was calculated. Linear regression was used to assess the expenditure for the forth coming years. The total ADE for the financial year of 2010–2011 was Rs. 1,91,44,253 which was only 7.68% of annual hospital expenditure. Using the inflation index, the indexed cost of acquisition of ADE for year 2010–2011 was Rs. 1,95,10,387. The difference between the two was estimated to be 2.11%. Thus, the CII justifies the demand of increased budget for next year and prompts us for cautious use of drugs. By taking into consideration the ADE of last 10 years, we have forecasted the budget for forthcoming years which will help significantly for making policies according to the available budget.

    The neonatal, infant, child, and maternal mortality rates in Haiti are the highest in the Western Hemisphere, with rates similar to those found in Afghanistan and several African countries. We identify several factors that have perpetuated this health care crisis and summarize the literature highlighting the most cost-effective, evidence-based interventions proved to decrease these mortality rates in low- and middle-income countries.To create a major change in Haiti's health care infrastructure, we are implementing two strategies that are unique for low-income countries: development of a countrywide network of geographic "community care grids" to facilitate implementation of frontline interventions, and the construction of a centrally located referral and teaching hospital to provide specialty care for communities throughout the country. This hospital strategy will leverage the proximity of Haiti to North America by mobilizing large numbers of North American medical volunteers to provide one-on-one mentoring for the Haitian medical staff. The first phase of this strategy will address the child and maternal health crisis.We have begun implementation of these evidence-based strategies that we believe will fast-track improvement in the child and maternal mortality rates throughout the country. We anticipate that, as we partner with private and public groups already working in Haiti, one day Haiti's health care system will be among the leaders in that region.

    Objective: Oral hygiene is important not only for maintaining health of teeth and gingivae in an individual but also for good and uneventful regeneration and healing of tissues, when one has undergone one or other dental treatments. This makes it important to have an understanding of oral hygiene practices employed by the population. Materials and Methodology: This descriptive cross-sectional hospital-based survey was carried out to know oral hygiene methods practiced by patients who visited Department of Dentistry at a Tertiary Care Hospital attached to medical college from Central Gujarat. While examining and recording their history, their mode of oral hygiene practice was also noted. Recorded data were entered in Microsoft Excel and analyzed in SPSS Statistics Version 17.0. The study reports proportions of the variables under study in percentages. Results: The patients ranged from 4 to 80 years in age with equal numbers from both genders. The number of participants using modern and scientific material and instrument for oral hygiene was good. However, majority of them performed it only once a day, and none after every meal or at bed time. Conclusion: There is a need to improve the frequency of oral hygiene procedure among the studied population as well as use of dental floss needs to be increased. PMID:27114949

    Background: Suicide is a significant public health issue. India currently has the largest number of suicides in the world and has a disproportionate number of youth suicides including young women. The studies on patterns of suicide in rural central India are sparse, particularly among tribal communities. Aims: The aim of this study is to describe the profile of suicide attempters presenting to a secondary-level hospital in rural central India and identify areas for potential future research toward preventive strategies. Materials and Methods: A retrospective chart review was carried out of eighty patients who were admitted with presenting complaints of deliberate self-harm and survived until psychiatric consultation. Descriptive statistics was employed to generate the results. Results and Conclusions: 86% of the attempts were isolated impulsive attempts following triggers, the most common of which was interpersonal disputes (71%). Only 67% of patients had a mental health condition, the most common syndrome being alcohol use disorder, followed by depression, and personality disorders. Although 45% of attempters had background interpersonal conflicts, only 5% reported financial stressors as contributory. Psychosocial stressors, especially interpersonal conflicts within the family, appear to be at least as important factors as mental illnesses in contributing to suicide attempts in the area.

    Aims and Objectives: To describe clinicopathological features of surgically resected vascular malformations (VMs) of central nervous system (CNS). Materials and Methods: Histologically diagnosed cases of VMs of CNS during April 2010–April 2014 were included. Demographic data, clinical and radiological features were obtained. Hematoxylin and eosin slides were reviewed along with Verhoeff-Van Gieson (VVG), Masson's trichrome, periodic acid-Schiff, and Perls' stains. Morphologically, cavernomas and arteriovenous malformations (AVMs) were distinguished on the basis of vessel wall features on VVG and intervening glial parenchyma. Results: Fifty cases were diagnosed as VMs of CNS with an age range of 14–62 years. These included 36 cavernomas, 12 AVMs, 2 mixed capillary-cavernous angiomas. Most of the cavernoma patients (15/36) presented with seizures, whereas AVM patients (8/12) had a headache as the dominant symptom. Twenty-nine patients were reliably diagnosed on radiological features. Microscopic evidence of hemorrhage was seen in 24/36 cavernomas and 6/12 AVMs, as opposed to radiologic evidence of 10 and 4, respectively. Reactive gliosis was seen in 16 cavernomas. Conclusions: Histological features are important for classifying the VMs of CNS as there are no specific clinical and radiological features. Type of VM has a bearing on management, prognosis, and risk of hemorrhage. PMID:27114659

    The multiple-locus variable-number repeat analysis of 90 human Brucella melitensis isolates from a large urban area in central Peru revealed variations at 4 (Bruce07, Bruce09, Bruce18, and Bruce42) out of 16 loci investigated, of which 1 (Bruce42) also is used for species identification. Ten genotypes were identified, separated by the number of Bruce42 repeats into two groups that may have distinct phenotypic characteristics. Whereas genotypes with five or six Bruce42 repeats were cultured mainly from adult patients, genotypes with three Bruce42 repeats were isolated from children and young adolescents as well as from adults. In addition, the isolates with three Bruce42 repeats were obtained more often from patients with splenomegaly (P = 0.02) or hepatomegaly (P = 0.006). An annual variation in the diversity of genotypes was observed, possibly reflecting changes in sources of fresh dairy products, supply routes to city shops and markets, and the movement of infected dairy goat herds.

    The reported long-term outcome of endemic Burkitt lymphoma (eBL) patients who present with paraplegia is largely unknown. Records of BL patients treated with comparable short-interval cyclophosphamide chemotherapy schedules between 2004 and 2014 at three Baptist mission hospitals in Cameroon were reviewed. Survivors were followed up and examined at home or in hospital. Eighty-seven of 948 (9.2%) patients had paraplegia at diagnosis. The survival rate in eBL patients with paraplegia at diagnosis was 33% (n = 29) after follow-up of between 2 and 96 (median 40) months. Seven patients (24%) had neurological sequelae and needed rehabilitation. There was no relationship between the duration of symptoms (<2, 2-4, >4 weeks) and the survival rate or the risk to have neurological sequelae. The survival rate and risk for sequelae were similar in patients with confirmed St. Jude stage III and IV diseases.

    Aquatic and semi-aquatic bugs (Heteroptera) represent a remarkable diversity and a resurging interest has been given to documenting at the species level these insects inhabiting Cameroon in Central Africa due to their potential implication in the transmission of the bacterium Mycobacterium ulcerans, the causal agent of Buruli ulcer, an emerging human disease. A survey was carried out over two years in Cameroon. Morphological analyses were done in two steps. A first step consisted in separating the specimens based on broadly shared characters into morphotypes. The specimens were then separated into two independent batches containing each the same representation of each morphotype. One batch (309 specimens) was used by taxonomy experts on aquatic bugs for species level identification and/or to reconcile nymph with their corresponding adult species. The second batch (188 specimens) was used to define species based on the COI DNA sequences (standard sequence used for "DNA barcoding") and using the Automatic Barcode Gap Discovery (ABGD) method. The first morphological analysis step separated the specimens into 63 different morphotypes (49 adults and 14 nymphs), which were then found to belong to 54 morphological species in the infra-orders Gerromorpha and Nepomorpha based on the species-level morphological identification, and 41-45 putative molecular species according to the gap value retained in the ABGD. Integrating morphology and "DNA barcoding" reconciled all the specimens into 62 aquatic bug species in Cameroon. Generally, we obtained a good congruence between species a priori identified based on morphology from adult morphotypes and molecular putative species. Moreover, molecular identification has allowed the association of 86% of nymphs with adults. This work illustrates the importance of integrative taxonomy.

    Lymphoedema, a condition of localized fluid retention, results from a compromised lymphatic system. Although one common cause in the tropics is infection with filarial worms, non-filarial lymphoedema, also known as podoconiosis, has been reported among barefoot farmers in volcanic highland zones of Africa, Central and South America and north-western India. There are conflicting reports on the causes of lymphoedema in the highland regions of Cameroon, where the condition is of great public-health importance. To characterise the focus of lymphoedema in the highlands of the North West province of Cameroon and investigate its real causes, a cross-sectional study was carried out on the adults (aged > or =15 years) living in the communities that fall within the Ndop and Tubah health districts. The subjects, who had to have lived in the study area for at least 10 years, were interviewed, examined clinically, and, when possible, checked for microfilaraemia. The cases of lymphoedema confirmed by ultrasonography and a random sample of the other subjects were also tested for filarial antigenaemia. The interviews, which explored knowledge, attitudes and perceptions (KAP) relating to lymphoedema, revealed that the condition was well known, with each study community having a local name for it. Of the 834 individuals examined clinically, 66 (8.1%) had lymphoedema of the lower limb, with all the clinical stages of this condition represented. None of the 792 individuals examined parasitologically, however, had microfilariae of W. bancrofti (or any other filarial parasite) in their peripheral blood, and only one (0.25%) of the 399 individuals tested for the circulating antigens of W. bancrofti gave a positive result. In addition, none of the 504 mosquitoes caught landing on human bait in the study area and dissected was found to harbour any stage of W. bancrofti. These findings indicate that the elephantiasis seen in the North West province of Cameroon is of non-filarial origin.

    Chinese herbal medicine (CHM), as the largest application category of traditional Chinese medicine (TCM), is widely accepted among cancer patients in China. Herbal slice (HS) and Chinese patent drug (CPD) are commonly used CHM in China. This study aimed to investigate the utilization of CHM among clinicians and cancer patients in central China. Five hundred and twenty-five patients and 165 clinicians in 35 comprehensive hospitals in central China were asked to complete an anonymous questionnaire that was designed to evaluate the use of CHM. The results showed that 90.74% clinicians and 72.24% cancer patients used CHM during cancer treatment. The educational backgrounds of the clinicians and the age, education level, annual income, and cancer stage of the cancer patients were related to use of CHM. More than 90% clinicians and cancer patients had used CPD. Comparatively, the percentage of HS use was 10% lower than that of CPD use among clinicians and cancer patients. More clinicians preferred to use CHM after surgery than cancer patients did (20.41% vs. 5.37%). Enhancing physical fitness and improving performance status were regarded as the most potential effect of CHM on cancer treatment (85.71% among clinicians and 94.07% among cancer patients), in comparison with directly killing tumor cells (24.49% among clinicians and 31.36% among patients). As for refusal reasons, imprecise efficacy was the unanimous (100%) reason for clinicians' rejection of CHM, and 95.58% patients objected to using CHM also for this reason. Furthermore, the side effects of CHM were more concerned by clinicians than by patients (33.33% vs. 15.81%). In conclusion, our survey revealed that CHM was popularly accepted by clinicians and cancer patients in central China. The reasons of use and rejection of CHM were different between clinicians and cancer patients.

    Since 1985, OCEAC, the organization for control of widespread endemic disease in Central Africa, has managed an epidemiological surveillance programme concerning HIV infection and AIDS in six countries of the Sub-Region: Cameroon, Tchad, Central African Republic, Congo, Equatorial Guinea and Gabon. This programme consists in evaluating longitudinally incidence rates of infection and clinical cases, and mortality rates. It is based on a selective strategy using a network of sentinels (hospitals and maternity care consultation centers), completed by cross sectional epidemiological studies. Thanks to this programme high risk groups of population, high risk places and high risk activities have been identified. These observations will be used to plan national prevention programmes on AIDS.

    The purpose of this retrospective study was to identify traumatic dental injuries by using the documentations of children (range 0-14 years, average age: 10.79±2.06) with dental trauma who referred to Cumhuriyet University, Faculty of Dentistry, Department of Pedodontics, in Sivas, Turkey, between January 2007 and June 2012. A total of 591 children (356 boys and 235 girls) with 1,287 injured teeth (394 primary and 893 permanent teeth) were included in the study. The children were evaluated in terms of gender, age, number of injured teeth, type of trauma, the interval between the traumatic event and time of seeking, and treatment procedures. The highest frequency of trauma occurred in the 12-14 year age group (14%). The most common type of injury was enamel-dentin fractures (58%) in primary teeth and complicated crown fractures (39%) in permanent teeth. Falls (30%) were the major cause of dental injury. Direct restoration (27%) without any endodontic treatment was the most common treatment procedure for permanent teeth. The most frequent treatment for primary teeth was examination and follow-up (42%). The upper central incisors (71%) were the mostly affected teeth in both primary and permanent teeth. Most dental trauma occurred in June and July (12%-8%). Only 63 children (11%) were referred to the clinic less than 30 minutes after trauma. Traumatic dental injury is considered a serious public health problems especially in children; parents and teachers should be informed on prevention and emergency management of traumatic dental injuries. In addition, the findings showed that initial treatment after dental trauma should be as quick as possible.

    Rheumatic heart disease is one of the most common cause for heart failure and associated mortalities/morbidities in the young population in developing countries like Nepal imparting huge familial, social and manpower burden. This is a hospital based descriptive cross-sectional study during June 2014 to April 2016 over a period of 22 months at College of Medical Sciences-Bharatpur including 235 patients with clinical and/or echocardiographic evidence of definite rheumatic heart disease. The age of the patients ranged from 7 to 76 years with mean age 39.82 ± 4.2 years with female preponderance (F:M = 2.1:1) (p < 0.01). Majority of the rheumatic heart disease patients belonged to 30-44 years (28.78%) followed by 15-29 years (25.75%) and 45-59 years (25.00%). Majority belonged to the low socioeconomic status (60.60%) (p < 0.05). The predominantly involved isolated valve was mitral in 110 patients (46.80%) followed by isolated aortic valve in 22 patients (9.36%) and 79 (33.62%) had dual valvular involvement. The common rheumatic valvular lesions were pure mitral stenosis in 32 (13.61%), isolated mitral regurgitation in 58 (24.68%), combined mitral stenosis/regurgitation in 36 (15.32%), combined mitral/aortic regurgitation in 23 (9.78%) and combined aortic stenosis/regurgitation in 18 (7.66%) patients with few overlappings. The common complications encountered were heart failure in 90 (38.30%) and arrhythmias in 124 (51.00%) patients.130 patients (55.32%) received injectable benzathine penicillin whereas 45 patients (19.15%) preferred oral penicillin V. Surgical intervention was done in 54 (22.97%) patients. 12 (5.10%) expired in the CCU during the course of treatment. RHD is a leading cause of heart failure among young populations with requirement of prolonged duration of medical treatment and many of them requiring surgery.

    Background. Infections with human immunodeficiency virus (HIV), hepatitis B (HBV), and hepatitis C virus (HCV) are currently major public health problems. Methods. A retrospective study was conducted from January to June 2008 at the Blood Bank of the Central Hospital, Yaoundé (Cameroon). The objective was to study the prevalence of HIV, HBV, and HCV and their coinfections among blood donors. Results. A total of 4650 donors were identified, and the sex ratio (male/female) was 14/1. The median age of donors was 28 years (range: 16 to 69 years). Among blood donors, HBV, HIV, and HCV infection prevalences were 12.14%  (n = 565) , 4.44%  (n = 206), and 1.44%  (n = 67), respectively. Coinfection with HIV and HBV was observed among 0.77% donors, followed by hepatitis B and C co-infection (0.21%) and HIV and HCV coinfection (0.06%). Co-infection with HIV-HBV-HCV was encountered in 2 donors. The HIV, HBV, and HCV infections lead to a destruction of one out of six sets of blood collected. Conclusion. There is a need to review policies for blood collection from donors, by modifying the algorithm of blood donors testing. Pretesting potential donors using rapid tests could help to avoid collection and destruction of (infected) blood. PMID:24066258

    Background.  Buruli ulcer is the third most common mycobacterial disease after tuberculosis and leprosy and is particularly frequent in rural West and Central Africa. However, the impact of HIV infection on BU severity and prevalence remains unclear. Methods.  This was a retrospective study of data collected at the Akonolinga District Hospital, Cameroon, from January 1, 2002 to March 27, 2013. Human immunodeficiency virus prevalence among BU patients was compared with regional HIV prevalence. Baseline characteristics of BU patients were compared between HIV-negative and HIV-positive patients and according to CD4 cell count strata in the latter group. Buruli ulcer time-to-healing was assessed in different CD4 count strata, and factors associated with BU main lesion size at baseline were identified. Results.  Human immunodeficiency virus prevalence among BU patients was significantly higher than the regional estimated prevalence in each group (children, 4.00% vs 0.68% [P < .001]; men, 17.0% vs 4.7% [P < .001]; women, 36.0% vs 8.0% [P < .001]). Individuals who were HIV positive had a more severe form of BU, with an increased severity in those with a higher level of immunosuppression. Low CD4 cell count was significantly associated with a larger main lesion size (β-coefficient, −0.50; P = .015; 95% confidence interval [CI], −0.91–0.10). Buruli ulcer time-to-healing was more than double in patients with a CD4 cell count below 500 cell/mm3 (hazard ratio, 2.39; P = .001; 95% CI, 1.44–3.98). Conclusion.  Patients who are HIV positive are at higher risk for BU. Human immunodeficiency virus-induced immunosuppression seems to have an impact on BU clinical presentation and disease evolution.

    The use of x-ray generators for diagnostic radiology in the medical sector in Cameroon, Central Africa, is wide spread and on the increase in recent times. Regulatory control of x-ray machines used in medical sector has been achieved in the Littoral Region of Cameroon by means of notification and authorization systems, routine inspections, and enforcement programs. Quality control of x-ray equipment is performed to test the components of the radiological system and verify that the equipment is operating satisfactorily before issuance of the authorization with a validity of two years. The Licensee has the responsibility to conduct internal QC of their own x-ray equipment to insure their safe use and quality care to patients. After a 2-y period, the authorization shall be renewed and a new quality control is carried out. Because Cameroon is a developing country, second hand x-ray machines are imported and radiation exposure control is required to ensure protection of workers, patients, and the public by measuring physical parameters of the x-ray generators and imaging devices at the time of commissioning. Forty-five x-ray machines located in the Littoral Region of Cameroon are considered. The authorization/registration program is implemented in the whole country, but the considered x-ray machines were identified because of the high number of medical examinations due to patients and workers to whom the annual routine medical examinations are required by their employers. Is appears by the present study that around 45% of x-ray machines are inappropriate for diagnostic radiology. Based on their state of operation, enforcement measures are taken to maintain them or to prohibit their use. Appropriate training of staff under ionizing radiation is part of the effort to develop the necessary awareness about safety culture. The acquired knowledge and skills ensure the required protection and safety at workplaces.

    Little information is available about the natural cycle of foot-and-mouth disease (FMD) in the absence of control measures such as vaccination. Cameroon presents a unique opportunity for epidemiological studies because FMD vaccination is not practiced. We carried out a prospective study including serological, antigenic and genetic aspects of FMD virus (FMDV) infections among different livestock production systems in the Far North of Cameroon to gain insight into the natural ecology of the virus. We found serological evidence of FMDV infection in over 75% of the animals sampled with no significant differences of prevalence observed among the sampled groups (i.e. market, sedentary, transboundary trade and mobile). We also found antibodies reactive to five of the seven FMDV serotypes (A, O, SAT1, SAT2 and SAT3) among the animals sampled. Finally, we were able to genetically characterize viruses obtained from clinical and subclinical FMD infections in Cameroon. Serotype O viruses grouped into two topotypes (West and East Africa). SAT2 viruses grouped with viruses from Central and Northern Africa, notably within the sublineage causing the large epidemic in Northern Africa in 2012, suggesting a common origin for these viruses. This research will guide future interventions for the control of FMD such as improved diagnostics, guidance for vaccine formulation and epidemiological understanding in support of the progressive control of FMD in Cameroon.

    Diabetes mellitus affects virtually all tissues and organs the body including the hard and soft issues of the oral cavity, manifesting with several complications. To assess the prevalence of oral diseases in diabetics and non-diabetics and to correlate oral diseases with glycaemic control. This was an observational study involving 149 diabetic patients recruited from hospitals in Southwest Region of Cameroon and 102 non-diabetic controls drawn from the general population. The study participants were aged 18 years and above. Data were collected using questionnaires, oral examination and laboratory tests. Oral examination was conducted to assess dental plaque, calculus, dental caries, periodontitis, gingivitis and candidiasis. Glycemic status was assessed by measuring glycated hemoglobin (HbA1c) levels using standardized methods. Thirty five out of 149 (23.5%) diabetic patients had gingivitis; 37 (24.8%) had periodontitis; 29 (19.5%) had dental caries and 32 (21.5%) had oral candidiasis. Gingivitis, periodontitis and oral candidiasis was significantly higher in diabetics than non-diabetics (P < 0.001). Also, more diabetic patients presented with poor oral hygiene than non-diabetics. Poorly controlled diabetics presented more with gingivitis and candidiasis than well-controlled diabetics and this relationship was statistically significant. The prevalence of oral disease was significantly higher in diabetics than in non-diabetic controls and hyperglycaemia seemed to be a major contributor to oral health in diabetic patients in the study area. Proper management of blood sugar levels might improve on the oral health of diabetes mellitus patients.

    This paper describes how the integration between one of the RIS-systems (Adapt) in VGR and the infobroker in the central archive is implemented. The project was presented in 2006 with the title Building an IT Healthcare Enterprise by taking the standards to the limits and sometimes beyond that. The Adapt RIS is used by the Sahlgrenska University Hospital (SU) in Gothenburg and handles 8 different radiology departments. The implementation is based on HL7 version 3 and the message exchange is based on Web Services/SOAP. The base of the RIS-system was developed in the beginning of the 1990:s by a company that no longer exists. SU has always been able to modify the system by changing the source code and we have been responsible for the system-development since late 1990s. We are using IBM Informix Dynamic Server that is running on a Solaris-based cluster with additional software from Veritas/Symantec. The communication is planned to be 2-way. Our RIS-system transfers order promises, various status updates during the workflow and finally reports with various status levels. Our system will be able to receive requests and reports from the broker. The broker in turn receives these messages from other hospitals in VGR (Vastra Gotalands Regionen). We use Axis2 to generate skeleton java-code based on WSDL- and XSD-files that defines the Web Services. Axis2 is an Open Source software that is developed as a part of the Apache project. Eclipse is a development environment for Java that we use and it is also open source. Apache Tomcat is the application server that we use to receive messages from the infobroker.

    We aimed to reliably describe the pattern of outpatient prescription of non-steroidal anti-inflammatory drugs (NSAIDs) and antibiotics (ATBs) at a central hospital in the West Bank, Palestine. This was a retrospective, cross-sectional study investigating a cohort of 2,208 prescriptions ordered by outpatient clinics and the emergency room over one year in Beit Jala Hospital in Bethlehem, West Bank. The orders were analysed for the rate and types of NSAIDs and ATBs utilised, and the appropriateness of these drugs to the diagnosis. Of the total prescriptions, 410 contained NSAIDs (18.6%), including diclofenac (40.2%), low dose aspirin (23.9%), ibuprofen (17.8%) and indomethacin (15.1%). A minority of these prescriptions contained a combination of these agents (2.5%). Only one prescription contained cyclooxyeganse-2 inhibitors (0.2%). The appropriateness of NSAID use to the diagnosis was as follows: appropriate (58.3%), inappropriate (14.4%) and difficult to tell (27.3%). The rate of ATB use was 30.3% (669 prescriptions). The ATBs prescribed were amoxicillin (23.3%), augmentin (14.3%), quinolones (12.7%), first and second generation cephalosporins (9.4% and 12.7%, respectively) and macrolides (7.2%). ATB combinations were identified in 9.4%, with the most common being second-generation cephalopsorins and metronidazole (4.3%). Regarding the appropriateness of prescribing ATBs according to the diagnosis, it was appropriate in 44.8%, inappropriate in 20.6% and difficult to tell in 34.6% of the prescriptions. These findings revealed a relatively large number and inappropriate utilisation of ATBs and NSAIDs. An interventional programme needs to be adopted to reinforce physicians' knowledge of the rational prescription of these agents.

    Few prospective follow-up studies evaluating the use of peripherally inserted central catheters (PICCs) to deliver chemotherapy and/or home parenteral nutrition (HPN) have focused exclusively on oncology outpatients. The aim of this prospective study was to assess the reliability and the safety of PICCs over a 5-year use in non-hospitalized cancer patients requiring long-term intravenous therapies. Since June 2008, all adult oncology outpatient candidates for PICC insertion were consecutively enrolled and the incidence of catheter-related complications was investigated. The follow-up continued until the PICC removal. Two hundred sixty-nine PICCs in 250 patients (98 % with solid malignancies) were studied, for a total of 55,293 catheter days (median dwell time 184 days, range 15-1,384). All patients received HPN and 71 % received chemotherapy during the study period. The incidence of catheter-related bloodstream infections (CRBSIs) was low (0.05 per 1,000 catheter days), PICC-related symptomatic thrombosis was rare (1.1 %; 0.05 per 1,000 catheter days), and mechanical complications were uncommon (13.1 %; 0.63 per 1,000 catheter days). The overall complication rate was 17.5 % (0.85 per 1,000 catheter days) and PICCs were removed because of complications only in 7 % of cases. The main findings of this study were that, if accurately managed, PICCs can be safely used in cancer patients receiving chemotherapy and/or HPN, recording a low incidence of CRBSI, thrombosis, and mechanical complications; a long catheter life span; and a low probability of catheter removal because of complications. Our study suggests that PICCs can be successfully utilized as safe and long-lasting venous access devices in non-hospitalized cancer patients.

    The psychoprophylactic method is one of the methods for providing 'painless childbirth without drugs' and was invented by applying I. Pavlov's theory of higher nervous activity. In 1951, it was adopted as a national policy in the Union of Soviet Socialist Republics. This method was then introduced in the People's Republic of China in 1952. In 1953, it was brought to Japan by Masatomo SUGAI, an obstetrician, and was introduced into the Central Hospital of Maternity of the Japanese Red Cross Society with the support of the director, Naotarou KUJI. The practice of this method by the research team, which consisted of the obstetricians and midwives of the Central Hospital of Maternity of the Japanese Red Cross Society and Oomori Red Cross Hospital, resulted in the initiation and characterization of the prenatal care program to encourage the autonomy of the pregnant women for normal parturition in the institutions of Japan.

    Rural India has an undetected load of HIV-positive individuals. Few rural adults present for HIV testing and counseling due to stigma, discrimination, and fear of social ostracization. In this rural hospital clinic-based study, we document profiles of rural adults seeking voluntary testing and counseling, and analyze correlates of HIV seropositivity. This cross-sectional study was conducted in 450 participants presenting to the outpatient clinics of Mahatma Gandhi Institute of Medical Sciences, Sevagram, Central India. After informed consent, pre- and post-test counseling, HIV testing, and face-to-face interviews were conducted. Data were collected using a structured questionnaire. The median age of the 450 study participants was 34 years (range 18-88 years); the majority (74%) was married. The overall proportion of HIV seropositivity was 32% [95% CI 28%, 37%]. The proportions of HIV seropositivity in married women, married men, and single men were 41%, 37%, 18%, respectively. No single woman was found seropositive in the study. Very few married women were aware of their husbands' HIV status. In a multivariate analysis, correlates of HIV seropositivity in men were: age 30-39 years, being married, having sex with multiple partners, use of alcohol before sex, and testing positive for HIV in the past. In married women, the only predictor of seropositivity was being married. Although limited by the non-random nature of the sampling method, this pilot study is unique in that it is the first from this rural region of Central India. It provides baseline data on marginalized, largely unstudied populations that may aid in designing probabilistic community-based surveys in this neglected population.

    This study demonstrates that most cholera deaths in this region of Cameroon occur out of hospital. This is a region which is prone to cholera, and interventions are needed to improve access to emergency medical care, especially during cholera outbreaks. Cameroon has experienced 14 cholera epidemics during the last 20 years, and these have had high case fatality rates. This study attempted to assess the effect of delays in seeking care and the locations of care as possible risk factors for cholera mortality. The study used data from a community-based survey regarding the circumstances of 97 fatal cases and 197 control (nonfatal) cases following a cholera-like syndrome in villages with cholera-like diseases during cholera outbreaks in Cameroon during 2009-2011. Deaths occurred in one of four environments: the community, in a temporary community treatment center (TCTC), in transit to a treatment center, or in a hospital (39%, 32%, 5%, and 24%, respectively). Using a case-control analysis, factors associated with deaths included the nonuse of a cholera treatment center, receiving health care in a TCTC instead of a hospital, and greater than 4 hours delay between the onset of symptoms and the decision to go to a treatment center (odds ratios of 17.1 [confidence interval (CI): 7.0-41.8], 2.5 [CI: 1.2-5.0], and 2.2 [CI: 1.0-4.6], respectively). During cholera epidemics, a higher proportion of deaths are still occurring in communities. The nonuse and delays in deciding to go a treatment center, and treatment at TCTC rather than a hospital were risk factors for death among patients with cholera-like syndrome in Cameroon. Informing people on community management of cholera-like syndrome and improving care in all health facilities are needed to reduce deaths during cholera epidemics.

    The epidemiology, referral patterns and outcome of patients admitted to a tertiary burns unit in southern Africa were reviewed. The charts of all patients with thermal injury presenting to the Burns Centre at Inkosi Albert Luthuli Central Hospital (IALCH) between 1 January 2008 and 31 December 2010 were reviewed. Information collected included age, gender, past medical history, cause of burn, size of burn, presence of inhalation injury, time before admission, time to excision, length of hospital stay, complications and mortality. Four hundred and sixty two patients were admitted, 296 (58%) children and 193 (42%) adults. The female-male ratio was 1:1.13. The mean total body surface area (TBSA) burned was 12% (interquartile range 8-25%) for children and 18% (interquartile range 10-35%) for adults. Common causes for the burns were in children: hot liquids (71%) and open flame (24%). Major causes in adults were: open fire (68%) and hot liquids (25%). Epilepsy was a contributing factor in 12.7%. Inhalation injury was seen in 13.6% of adults and 14.3% of children with a flame burn. Forty-four percent of referrals from general surgical units were for burns <30% in adults, and 30% for burns <10% in children. More than one in four patients was referred between 1 and 6 weeks post-injury. Overall mortality was 9.1% (5.7% in children and 15.1% in adults). Complications occurred in 21.6% of children and 36.7% in adults, the most common being lung complications such as ARDS and infection, severe sepsis, skin graft failure and contractures. The length of stay was 1 day/% TBSA burn for all burns in children and for burns between 10 and 49% in adults. The epidemiology and outcome of severe burns referred to the Burns Centre at IALCH is similar to those in other units in Africa. The management and referral of burns patients by other hospitals are inappropriate in a significant number of patients. Copyright © 2014. Published by Elsevier Ltd.

    Campanian-Maastrichtian marine sediments outcrop in five genetically linked sedimentary basins along the West African coast in the Gulf of Guinea, from the Douala Basin in Cameroon to the Anambra Basin in Nigeria. These sediments in the more centrally located Rio del Rey Basin have been the least studied. Therefore, the geologic history of this region has merely been speculative. The Rio del Rey Basin like the adjacent Niger Delta is producing hydrocarbon from the offshore Tertiary sedimentary interval in which all studies have been focused, neglecting the onshore Cretaceous sediments. Outcrops in the basin are rare, small and highly weathered. Samples from some of these sediments have yielded a few Planktonic and dominantly benthonic foraminiferal assemblages. The long-ranging heterohelix and hedbergellids characterized the planktics while the species Afrobolivina afra which is a well known diagnostic taxon for Campanian-Maastrichtian sediments in West African basins clearly dominate the benthic assemblage. Its occurrence in association with other Upper Cretaceous forms such as Bolivina explicata, Praebulimina exiqua, Gabonita lata, Ammobaculites coprolithiformis amongst others, formed the basis on which this age was assigned to the sediments sampled from the Rio del Rey Basin. Hence, this work has undoubtedly established the much needed link in this regional geologic history and correlates these sediments with the Logbaba and Nkporo Formations in the Douala Basin in Cameroon and the southeastern Nigerian Sedimentary Basins. Thus, these units were all deposited during this same geologic period and probably controlled by the same geologic event.

    The following is a population-based survey of the Central African Republic (CAR) female refugee population displaced to rural Djohong District of Eastern Cameroon and associated female Cameroonian host population to characterise the prevalence and circumstances of sexual violence. A population-based, multistage, random cluster survey of 600 female heads of household was conducted during March 2010. Women heads of household were asked about demographics, household economy and assets, level of education and sexual violence experienced by the respondent only. The respondents were asked to describe the circumstances of their recent assault. The lifetime prevalence of sexual violence among Djohong district female heads of household is 35.2% (95% CI 28.7-42.2). Among heads of household who reported a lifetime incident of sexual violence, 64.0% (95% CI 54.3-72.5) suffered sexual violence perpetrated by their husband or partner. Among the host population, 3.9% (95% CI 1.4-10.5) reported sexual violence by armed groups compared to 39.0% (95% CI 25.6-54.2) of female refugee heads of household. Women who knew how to add and subtract were less likely to report sexual violence during their lifetime (OR 0.16, 95% CI 0.08-0.34). Sexual violence is common among refugees and host population in Eastern Cameroon. Most often, perpetrators are partners/husbands or armed groups.

    Poor retention in care is common among HIV-positive adults in sub-Saharan Africa settings and remains a key barrier to HIV management. We quantify the associations of disclosure of HIV status and referral to disclosure counseling with successful retention in care using data from three Cameroon clinics participating in the Phase 1 International epidemiologic Databases to Evaluate AIDS Central Africa cohort. Of 1646 patients newly initiating antiretroviral therapy between January 2008 and January 2011, 43% were retained in care following treatment initiation. Self-disclosure of HIV status to at least one person prior to treatment initiation was associated with a minimal increase in the likelihood of being retained in care (risk ratio [RR] = 1.14; 95% confidence interval (CI): 0.94, 1.38). However, referral to disclosure counseling was associated with a moderate increase in retention (RR = 1.37; 95% CI: 1.21, 1.55) and was not significantly modified by prior disclosure status (p = .3). Our results suggest that while self-disclosure may not significantly improve retention among patients receiving care at these Cameroon sites, counseling services may play an important role regardless of prior disclosure status.

    Efficient and effective disaster management will prevent many hazardous events from becoming disasters. This paper constitutes the most comprehensive document on the natural disaster management framework of Cameroon. It reviews critically disaster management in Cameroon, examining the various legislative, institutional, and administrative frameworks that help to facilitate the process. Furthermore, it illuminates the vital role that disaster managers at the national, regional, and local level play to ease the process. Using empirical data, the study analyses the efficiency and effectiveness of the actions of disaster managers. Its findings reveal inadequate disaster management policies, poor coordination between disaster management institutions at the national level, the lack of trained disaster managers, a skewed disaster management system, and a top-down hierarchical structure within Cameroon's disaster management framework. By scrutinising the disaster management framework of the country, policy recommendations based on the research findings are made on the institutional and administrative frameworks. © 2014 The Author(s).

    Introduction. Epistaxis is one of the most common emergencies in Otorhinolaryngology. It is usually managed with simple conservative measures but occasionally it is a life threatening condition. Identification of the cause is important, as it reflects the management plan being followed. Aims and Objectives. To analyze the etiology and treatment methods for patients with epistaxis. Methods. A retrospective study was done in a tertiary care hospital in central Nepal. The study period was from May 2014 to April 2015. Results. A total of 84 patients had epistaxis; 52 were males and 32 were females. The most common cause of epistaxis was idiopathic (38.09%) followed by hypertension (27.38%), trauma (15.47%), and coagulopathy (8.33%). Regarding treatment methods, most (52.38%) of our patients required anterior nasal packing. Chemical cautery was sufficient to stop bleeding in 14.28% of patients while electrocautery and posterior nasal packing were performed in 2.38% and 16.66% patients, respectively. Two (2.38%) patients required endoscopic sphenopalatine arterial ligation. Conclusion. Hypertension, trauma and coagulopathy were the most common etiological factors among the patients in whom etiology was found although in most of the patients etiology could not be found. Anterior nasal packing was the most common treatment method applied to these patients. PMID:26346242

    Setting: South Africa reports more cases of tuberculosis (TB) than any other country, but an up-to-date, precise estimate of the costs associated with diagnosing, treating and preventing TB at the in-patient level is not available. Objective: To determine the costs associated with TB management among in-patients and to study the use of personal protective equipment (PPE) at a central academic hospital in Cape Town. Design: Retrospective and partly prospective cost analysis of TB cases diagnosed between May 2008 and October 2009. Results: The average daily in-patient costs were US$238; the average length of stay was 9.7 days. Mean laboratory and medication costs per stay were respectively US$26.82 and US$8.68. PPE use per day cost US$0.99. The average total TB management costs were US$2373 per patient. PPE was not always properly used. Discussion: The costs of in-patient TB management are high compared to community-based treatment; the main reason for the high costs is the high number of in-patient days. An efficiency assessment is needed to reduce costs. Cost reduction per TB case prevented was approximately US$2373 per case. PPE use accounted for the lowest costs. Training is needed to improve PPE use. PMID:26392953

    Human respiratory syncytial virus group A (RSV-A) was detected in symptomatic hospital attended children in Central Spain for a continuous time period, September 2010 to April 2015. In order to accurately describe the epidemiology of this virus, the genetic diversity of the complete G gene and the clinical manifestations observed were jointly analyzed. Out of 3,011 respiratory specimens taken from 2,308 children, 640 were positive to RSV (21.3%) and 405 were RSV-A (63.2%). Complete G gene sequences of 166 randomly selected RSV-A virus identified NA1 and ON1 genotypes. In 2011-2012, ON1 emerged sporadically and become dominant in 2012-2013 with 38 cases (70%). In 2014-2015, all the 44 sequences contained the 72-nt duplication (100%). Clinical diagnosis of children with ON1 genotype were bronchiolitis in 55 (62.5%), recurrent wheezing or asthma exacerbations in 22 (25%), laryngotracheobronchitis in 3 (3.4%), and upper respiratory tract infections in eight. Results showed replacement and substitution of circulating NA1 genotype with the new ON1 genotype. Nevertheless, at this stage, none of the RSV-A genotypes identified have resulted in significant clinical differences. The amino acid composition of the complete G gene ON1 sequences demonstrated an accumulation of single changes not related with different clinical presentation. J. Med.

    Primary health care in Cameroon meets with serious obstacles. The state gives it a low priority in its budget and over-all policy. The health institutions are rarely active in this field. Institutions which do practice some primary health care are usually foreign. The villagers, finally, are little interested. They insist only on improvement of curative services and material life conditions. The conclusion is that primary health care is regarded as something of secondary importance. First comes a better life. The research for this paper was conducted in 1980 in the South of Cameroon.

    OBJECTIVE To evaluate the concordance of case-finding methods for central line–associated infection as defined by Centers for Medicare and Medicaid Services (CMS) hospital-acquired condition (HAC) compared with traditional infection control (IC) methods. SETTING One tertiary care and 2 community hospitals in North Carolina. PATIENTS Adult and pediatric hospitalized patients determined to have central line infection by either case-finding method. METHODS We performed a retrospective comparative analysis of infection detected using HAC versus standard IC central line–associated bloodstream infection surveillance from October 1, 2007, through December 31, 2009. One billing and 2 IC databases were queried and matched to determine the number and concordance of cases identified by each method. Manual review of 25 cases from each discordant category was performed. Sensitivity and positive predictive value (PPV) were calculated using IC as criterion standard. RESULTS A total of 1,505 cases were identified: 844 by International Classification of Diseases, Ninth Revision (ICD-9), and 798 by IC. A total of 204 cases (24%) identified by ICD-9 were deemed not present at hospital admission by coders. Only 112 cases (13%) were concordant. HAC sensitivity was 14% and PPV was 55% compared with IC. Concordance was low regardless of hospital type. Primary reasons for discordance included differences in surveillance and clinical definitions, clinical uncertainty, and poor documentation. CONCLUSIONS The case-finding method used by CMS HAC and the methods used for traditional IC surveillance frequently do not agree. This can lead to conflicting results when these 2 measures are used as hospital quality metrics. PMID:23388357

    Abstract Admission rate and length of stay (LOS) are two hospital performance indicators that affect the quality of care, patients’ satisfaction, bed turnover, and health cost expenditures. The aim of the study was to identify factors associated with higher admission rates and extended average LOS among acutely poisoned children at a single poison center, central Saudi Arabia. This is a cross-sectional, poison and medical chart review between 2009 and 2011. Exposures were child characteristics, that is, gender, age, body mass index (BMI), health history, and Canadian 5-level triage scale. Poison incident characteristics were, that is, type, exposure route, amount, form, home remedy, and arrival time to center. Admission status and LOS were obtained from records. Chronic poisoning, plant allergies, and venomous bites were excluded. Bivariate and regression analyses were applied. Significance at P < 0.05. Of the 315 eligible cases, (72%) were toddlers with equal gender distribution, (58%) had normal BMI, and (77%) were previously healthy. Poison substances were pharmaceutical drugs (63%) versus chemical products (37%). Main exposure route was oral (98%). Home remedy was observed in (21.9%), which were fluids, solutes, and/or gag-induced vomiting. Almost (52%) arrived to center >1 h. Triage levels: non-urgent cases (58%), less urgent (11%), urgent (18%), emergency (12%), resuscitative (1%). Admission rate was (20.6%) whereas av. LOS was 13 ± 22 h. After adjusting and controlling for confounders, older children (adj.OR = 1.19) and more critical triage levels (adj.OR = 1.35) were significantly associated with higher admission rates compared to younger children and less critical triage levels (adj.P = 0.006) and (adj.P = 0.042) respectively.

    The application of information technologies and telecommunications in healthcare in southern countries can improve the health of millions of people living in poverty without access to high-quality health services. Specifically, telemedicine not synchronized with internet platforms is a very efficient option for international cooperation projects. Since its inception, the project Health 2.0: professionals from Africa-Spain connected, of the Spanish organization, Foundation Recover, Hospitals for Africa, has managed to connect health professionals from both continents with the goal of improving health in Cameroon. Thanks to a social network with the scientific format of case management and clinical updates, Spanish physicians collaborate through volunteer e-health in the training of their African colleagues to improve the quality of care provided to residents and also create sources of knowledge and research.

    Teledermatology is a rapidly expanding niche within telemedicine still in its infancy. It has become increasingly more feasible in recent years with the expansion of information and communication technologies. Here, the authors present the details of their collaboration and propose a model for constructing a teledermatology network. In the year 2014, the authors’ Dermatopathology institute in Torrance, California, partnered with Mbingo Baptist Hospital, a tertiary referral center in Cameroon, Africa. During this time, 145 cases were received. The authors present highlights of specific cases as well as the strengths and challenges encountered. They have found the use of the store and forward method to be an effective tool with an acceptable concordance rate. With basic bandwidth speeds and images taken with smart devices shared via email, providers are given the unique opportunity to provide specialty care and alleviate disease burden where dermatology and dermatopathology resources are scarce.

    Tuberculosis (TB) is a major cause of mortality and suffering worldwide, with over 95% of TB deaths occurring in low- and middle-income countries. In recent years, molecular typing methods have been widely used in epidemiological studies to aid the control of TB, but this usage has not been the case with many African countries, including Cameroon. The aims of the present investigation were to identify and evaluate the diversity of the Mycobacterium tuberculosis complex (MTBC) isolates circulating in two ecological zones of Cameroon, seven years after the last studies in the West Region, and after the re-organization of the National TB Control Program (NTBCP). These were expected to shed light also on the transmission of TB in the country. The study was conducted from February to July 2009. During this period, 169 patients with symptomatic disease and with sputum cultures that were positive for MTBC were randomly selected for the study from amongst 964 suspected patients in the savannah mosaic zone (West and North West regions) and the tropical rainforest zone (Central region). After culture and diagnosis, DNA was extracted from each of the MTBC isolates and transported to the BecA-ILRI Hub in Nairobi, Kenya for molecular analysis. Genetic characterization was done by mycobacterial interspersed repetitive unit-variable number tandem repeat typing (MIRU-VNTR) and Spoligotyping. Molecular analysis showed that all TB cases reported in this study were caused by infections with Mycobacterium tuberculosis (98.8%) and Mycobacterium africanum (M. africanum) (1.2%) respectively. We did not detect any M. bovis. Comparative analyses using spoligotyping revealed that the majority of isolates belong to major clades of M. tuberculosis: Haarlem (7.6%), Latin American-Mediterranean (34.4%) and T clade (26.7%); the remaining isolates (31.3%) where distributed among the minor clades. The predominant group of isolates (34.4%) corresponded to spoligotype 61, previously described as the

    Hospital-treated deliberate self-poisoning (DSP) by central nervous system depressant drugs (CNS-D) has been associated with impairments in cognitive and psychomotor functions at the time of discharge. We aimed to replicate this finding and to compare recovery in the first month after discharge for CNS-D and CNS nondepressant drug ingestions. We also examined a series of multivariate explanatory models of recovery of neurocognitive outcomes over time. The CNS-D group was impaired at discharge compared with the CNS-nondepressant group in cognitive flexibility, cognitive efficiency, and working memory. There were no significant differences at discharge in visual attention, processing speed, visuomotor speed, or inhibition speed. Both groups improved in the latter measures over 1 month of follow-up. However, the CNS-D group's recovery was significantly slower for key neurocognitive domains underlying driving in complex traffic situations, namely, cognitive flexibility, cognitive efficiency, and working memory. Patients discharged after DSP with CNS-D drugs have impairments of some critical cognitive functions that may require up to 1 month to recover. Although more pre- than post-DSP variables were retained as explanatory models of neurocognitive performance overall, recovery over time could not be explained by any one of the measured covariates. Tests of cognitive flexibility could be used in clinical settings as a proxy measure for recovery of driving ability. Regulatory authorities should also consider the implications of these results for the period of nondriving advised after ingestion of CNS-D in overdose. Future research, with adequate sample size, should examine contributions of other variables to the pattern of recovery over time.

    Blood lead levels have decreased following the removal of lead from gasoline in most of the world. However, numerous recent studies provide evidence that elevated blood lead levels persist in many low and middle-income countries around the world at much higher prevalence than in the more developed countries. One potential source of lead exposure that has not been widely investigated is the leaching of lead from artisanal aluminum cookware, which is commonly used in the developing world. Twenty-nine samples of aluminum cookware and utensils manufactured by local artisans in Cameroon were collected and analyzed for their potential to release lead during cooking. Source materials for this cookware included scrap metal such as engine parts, radiators, cans, and construction materials. The lead content of this cookware is relatively low (<1000 ppm by X-ray fluorescence), however significant amounts of lead, as well as aluminum and cadmium were released from many of the samples using dilute acetic acid extractions at boiling and ambient temperatures. Potential exposures to lead per serving were estimated to be as high as 260 μg, indicating that such cookware can pose a serious health hazard. We conclude that lead, aluminum and cadmium can migrate from this aluminum cookware during cooking and enter food at levels exceeding recommended public health guidelines. Our results support the need to regulate lead content of materials used to manufacture these pots. Artisanal aluminum cookware may be a major contributor to lead poisoning throughout the developing world. Testing of aluminum cookware in other developing countries is warranted.

    This paper is dedicated to Soba Djallo, Director of IRGM, who died in 1991 Results of seismic monitoring of the continental segment of the Cameroon Volcanic Line for the period 1982 to 1990 are reported. Mount Cameroon continues to be seismically the most active area with a well defined seismicity pattern characterized by single and swarm events with duration magnitudes between 2 and 3 occurring at depths down to 55 km. On average, the earthquakes here occur at the rate of about 2 events every 3 days. Further north, the seismicity is low except for isolated felt events located along the Foumban Shear Zone which probably controls the location of the earthquakes as well as the volcanic centres making up the volcanic line. During this eight-year period two fatal carbon dioxide gas emissions from crater lakes occurred in 1984 (L. Monoun) and 1986 (L. Nyos) causing 37 and 1700 deaths respectively. Seismic monitoring indicates that no seismic activity was associated with these lakes thus favouring an aseismic cause to the disasters. These gas emissions, the increased number of felt earthquakes and a recent natural explosion on Mount Cameroon suggest either a more active phase of the Cameroon Volcanic Line and/or a greater awareness by the local population of the phenomena associated with this volcanic province.

  14. Uncovering high rates of unsafe injection equipment reuse in rural Cameroon: validation of a survey instrument that probes for specific misconceptions

    PubMed Central

    2011-01-01

    Background Unsafe reuse of injection equipment in hospitals is an on-going threat to patient safety in many parts of Africa. The extent of this problem is difficult to measure. Standard WHO injection safety assessment protocols used in the 2003 national injection safety assessment in Cameroon are problematic because health workers often behave differently under the observation of visitors. The main objective of this study is to assess the extent of unsafe injection equipment reuse and potential for blood-borne virus transmission in Cameroon. This can be done by probing for misconceptions about injection safety that explain reuse without sterilization. These misconceptions concern useless precautions against cross-contamination, i.e. "indirect reuse" of injection equipment. To investigate whether a shortage of supply explains unsafe reuse, we compared our survey data against records of purchases. Methods All health workers at public hospitals in two health districts in the Northwest Province of Cameroon were interviewed about their own injection practices. Injection equipment supply purchase records documented for January to December 2009 were compared with self-reported rates of syringe reuse. The number of HIV, HBV and HCV infections that result from unsafe medical injections in these health districts is estimated from the frequency of unsafe reuse, the number of injections performed, the probability that reused injection equipment had just been used on an infected patient, the size of the susceptible population, and the transmission efficiency of each virus in an injection. Results Injection equipment reuse occurs commonly in the Northwest Province of Cameroon, practiced by 44% of health workers at public hospitals. Self-reported rates of syringe reuse only partly explained by records on injection equipment supplied to these hospitals, showing a shortage of syringes where syringes are reused. Injection safety interventions could prevent an estimated 14-336 HIV

    Inhabitants of the Mount Cameroon region depend on the forest resources of the region for their livelihood, including the diverse use of macrofungi. With the increasing loss of forest due to exploitation and urbanization, they are liable to rapidly lose their indigenous knowledge of the forest resources, especially of mushrooms. An ethnomycological survey was conducted with the aim of documenting the indigenous knowledge of mushrooms as a prelude to conservation efforts. We also sought to assess the mycophilic and mycophobic tendencies of the inhabitants. It was revealed that traditionally, mushrooms were used as food, medicine, for mythological purposes, for aesthetics, and some poisonous species were also recorded. At least 15 different species were identified to be edible among the Bakweri people.

Mushrooms were used as love charms, for dispelling evil spirits, and as part of cultural festivals.

    A multimodal hospital-wide central line-associated bloodstream infection (CLABSI) risk reduction strategy was implemented over a 20-month period at an Australian center. Reduced CLABSI rates were observed in both intensive care units (ICUs) (incidence rate ratio [IRR], 0.39; P < .001) and non-ICU wards (IRR, 0.54; P < .001). The median time to CLABSI onset was 7.5 days for ICU events and 13 days for non-ICU events. The timing of infection demonstrates the need for more careful attention to postinsertion care and access of central venous catheters.

    Introduction In Cameroon, cholera has periodically resurfaced since it was first reported in 1971. In 2003, Cameroon adapted the Integrated Disease Surveillance and Response (IDSR) strategy to strengthen surveillance in the country. This study was an in-depth description and assessment of the structure, core and support functions, and attributes of the current cholera surveillance system in Cameroon. It also discussed its strengths and challenges with hope that lessons learned could improve the system in Cameroon and in other countries in Africa implementing the IDSR strategy. Methods Semi-structured key informant interviews, peer reviewed articles, and government record review were conducted in the Far North and Centre Regions of Cameroon. We used the matrix and conceptual framework from the World Health Organization (WHO) and Centers for Disease Control and Prevention, WHO Regional Office for Africa Technical Guidelines to frame the study. Site visits included the WHO country office, the ministry of public health (MoPH), two Regional Public Health Delegations (RPHDs), eight health districts (HDs) and health facilities (HFs) including two labs. Results Cholera surveillance is passive but turns active during outbreaks and follows a hierarchical structure. Cholera data are collected at HFs and sent to HDs where data are compiled and sent to the RPHD in paper format. RPHDs de-identify, digitalize, and send the data to the MoPH via internet and from there to the WHO. The case definition was officially changed in 2010 but the outdated definition was still in use in 2013. Nationally, there are 3 laboratories that have the ability to confirm cholera cases; the lack of laboratory capacity at HFs hampers case and outbreak confirmation. The absence of structured data analysis at the RPHD, HD, and HF further compounds the situation, making the goal of IDSR of data analysis and rapid response at the HD very challenging. Feedback is strongest at the central level (MoPH) and

    The Pan-African NE-SW elongated Bandja granitic pluton, located at the western part of the Pan-African belt in Cameroon, is a K-feldspar megacryst granite. It is emplaced in banded gneiss and its NW border underwent mylonitization. The magmatic foliation shows NE-SW and NNE-SSW strike directions with moderate to strong dip respectively in its northern and central parts. This mostly, ferromagnetic granite displays magnetic fabrics carried by magnetite and characterized by (i) magnetic foliation with best poles at 295/34, 283/33 and 35/59 respectively in its northern, central and southern parts and (ii) a subhorizontal magnetic lineation with best line at 37/8, 191/9 and 267/22 respectively in the northern, central and southern parts. Magnetic lineation shows an `S' shape trend that allows to (1) consider the complete emplacement and deformation of the pluton during the Pan-African D 2 and D 3 events which occurred in the Pan-African belt in Cameroon and (2) reorganize Pan-African ages from Nguiessi Tchakam et al. (1997) compared with those of the other granitic plutons in the belt as: 686 ±17 Ma (Rb/Sr) for D 1 age of metamorphism recorded in gneiss; and the period between 604-557 Ma for D 2-D 3 emplacement and deformation age of the granitic pluton in a dextral ENE-WSW shear movement.

    Data on the economic burden of rotavirus infection in Tunisia are needed to inform the decision to include rotavirus in routine childhood immunizations. This study aimed to describe the epidemiological profile of rotavirus disease in central-east Tunisia and to estimate its hospital cost. In the first stage - the prospective collection of epidemiological data - we enrolled all patients < 5 years old who were hospitalized for acute diarrhoea at 5 university paediatric departments in central-east Tunisia during the period 2009-2011. Rotavirus was responsible for 65 (23.3%) of the 279 cases enrolled. In the second stage, cost data were collected retrospectively using an activity-based costing method from the medical records of the children who were positively diagnosed with rotavirus. The average cost of care per child was TD 433 (SD 134). This is a significant economic burden in Tunisia, where a safe and effective vaccine is available but not yet introduced to the immunization schedule.

    Background Cardiovascular disease is an increasingly important issue in human immunodeficiency viral (HIV)-infected individuals. There is dearth of information on the patterns of cardiovascular disease especially in sub-Saharan Africa (SSA) patients. This study reports on the clinical, biological, electrocardiographic and echocardiographic characteristics of a group of HIV-infected patients presenting with symptoms of heart disease in Yaoundé, Cameroon. Methods This was a cross-sectional study conducted at the Yaoundé Central Hospital and Jamot Hospital. Consenting HIV-infected adults aged ≥18 years with symptoms suggestive of heart disease were consecutively recruited between February and July 2014. All participants underwent a complete clinical examination; biological analyses including CD4 cell counts, fasting blood glucose, and serum lipids, resting electrocardiography and cardiac ultrasound, and a venous ultrasound where necessary. Results Forty four subjects (21 men) were included. Their mean age was 48 (SD 13) years. Thirty patients (68.2%) were in WHO clinical stages 3 and 4 of HIV infection, 27 (61.4%) had a CD4 cell count <200/mm3, and 31 (70.5%) were on antiretroviral therapy (ART). Hypertension (43.2%, n=19) was the most frequent cardiovascular risk factor; and dyslipidemia which was found in 17 subjects (38.6%) was significantly associated with ART (48.4% vs. 15.4%, P=0.04). Only men where smokers (23% vs. 0%, P=0.019). Exertional dyspnea (86.4%, n=38) and cough (59.1%, n=26) were the most frequent symptoms, and the clinical presentation was dominated by heart failure (75%, n=33). The most frequent echocardiographic abnormalities were pericardial effusion (45.5%, n=20) and dilated cardiomyopathy (22.7%, n=10). Dilated cardiomyopathy was significantly associated with CD4 cell counts <200/mm3 (100%, P=0.003). Primary pulmonary hypertension (PH) rate was 11.4% (n=5) and all cases occurred at CD4 cell counts ≥200/mm3 (P=0.005). The most frequent

    Water containing high concentrations of nitrate is unfit for human consumption and, if discharging to freshwater or marine habitats, can contribute to algal blooms and eutrophication. The level of nitrate contamination in groundwater of two densely populated, agro-industrial areas of the Cameroon Volcanic Line (CVL) (Banana Plain and Mount Cameroon area) was evaluated. A total of 100 samples from boreholes, open wells and springs (67 from the Banana Plain; 33 from springs only, in the Mount Cameroon area) were collected in April 2009 and January 2010 and analyzed for chemical constituents, including nitrates. The average groundwater nitrate concentrations for the studied areas are: 17.28 mg/l for the Banana Plain and 2.90 mg/l for the Mount Cameroon area. Overall, groundwaters are relatively free from excessive nitrate contamination, with nitrate concentrations in only 6 % of groundwater resources in the Banana Plain exceeding the maximum admissible concentration for drinking water (50 mg/l). Sources of NO3 - in groundwater of this region may be mainly anthropogenic (N-fertilizers, sewerage, animal waste, organic manure, pit latrines, etc.). Multivariate statistical analyses of the hydrochemical data revealed that three factors were responsible for the groundwater chemistry (especially, degree of nitrate contamination): (1) a geogenic factor; (2) nitrate contamination factor; (3) ionic enrichment factor. The impact of anthropogenic activities, especially groundwater nitrate contamination, is more accentuated in the Banana Plain than in the Mount Cameroon area. This study also demonstrates the usefulness of multivariate statistical analysis in groundwater study as a supplementary tool for interpretation of complex hydrochemical data sets.

    There are no epidemiological studies comparing the prevalence of skin diseases between civilian and military populations. We sought to determine and compare the prevalence of skin conditions between civilian and military populations. A total of 3382 male patients (1148 military and 2234 civilian) were retrospectively and consecutively evaluated at Merzifon Military Hospital in the central Black Sea Region of Turkey. The most frequent dermatological condition was tinea pedis (15.8%) followed by acne vulgaris, allergic contact dermatitis and alopecia areata in the military population (15.7%, 7.7% and 5.4%, respectively). Acne vulgaris, xerosis cutis and allergic contact dermatitis were the most common diagnoses in the civilian group (19.4%, 14.1% and 9.1%, respectively). The prevalence of tinea pedis, alopecia areata, pityriasis versicolor, ingrown nail (unguis incarnatus) and callus were statistically significantly higher in the military group (15.8% vs 4.4%, p<0.001; 5.4% vs 1.7%, p<0.05; 3.5% vs 0.7%, p<0.001; 3.3% vs 0.3%, p<0.001 and 4.6% vs 0.9%, p<0.001; respectively). Xerosis cutis was found to be significantly higher in the civilian group (14.1% vs 5.8%, p<0.001). Superficial fungal disease was the most prevalent disorder as in the previous literature. Preventive measures should be taken to improve the health of troops and reduce the prevalence of the common disorders such as tinea pedis, alopecia areata and callus. Troops should wear boots only when necessary in base camps. Clothing which reduces ventilation is not recommended. Depression and anxiety should be recognised and treated in soldiers with alopecia areata, as a solely dermatological approach without psychological support may reduce treatment success.

    Ritual tooth mutilation is a relatively understudied human body mutilatory practices. The purpose of the study was to examine the effects of ritual tooth modification, teeth cleaning measures and herbal medications for their oral health problems among the Baka pygmies in Cameroon. This cross-sectional study was conducted between January and March, 2012 using semi-structured questionnaire as the tool of data collection. Intra-oral examinations were carried out to determine the dental hard tissue loss using Smith and Knight Tooth Wear Index (TWI). Fifty-six pygmies with ritual tooth modification made of 34 males (60.7%) and 22 females (39.3%) with a mean age of 31 years were interviewed and had oral health examination. The reported age at which the tooth modification was done was between 10 and 15 years with mean age as 12 ± 1.66 years. More than half (58.9%) of the participants reported the tooth filing as painful and nearly two-thirds (64.3%) of the participants reported having persistent pain afterwards. The upper right central and lateral incisors were the most commonly modified teeth. A total of 42.9%, 12.5% and 7.1% of the participants had Smith and Knight TWI scores of 2, 3 and 4 respectively. All the participants reported cleaning their teeth at least once-daily with about two-thirds (66.1%) of them doing so with chewing stick. The majority (67.9%) of the participants reported cleaning their teeth for cosmetic reasons [to remove dirt' (60.7%) and 'to remove stains' (7.1%)]. The oral health problems among the participants in form of tooth sensitivity, toothache and dental abscess were treated with plant-based traditional medicines from Irvingia gabonensis, Ricinodendron heudoletti, Pterocarpus soyauxii, Alchornea cordifolia and Piptadeniastrum africanum. Ritual tooth modification is a painful mutilatory practice which is culturally significant for the Baka pygmies without health benefit. There is need for intervention to stop this harmful traditional

    Because it already has over 30 years of experience in preparing and executing 5-year plans, Cameroon was chosen as the case study for a workshop on training of African planners in population, human resources, and development planning. This communication, based on analysis of the 1st 5 plans and preparatory documents for the 6th, is divided into 4 chapters. The 1st chapter studies the methodology and structures for plan development and the models used in projections and forecasts. The 2nd chapter discusses sectorial programs while the 3rd examines the place of population in the different plans. The final chapter proposes a practical approach to planning of population, human resources, and development in Africa. Cameroon's experience in planning is instructive because it shows the growing consciousness of the importance of population factors and the progressive integration of demographic variables in the plans. The 20-year process began with construction of planning structures at the central, regional, and provincial levels, followed by constitution of series of demographic data and finally the establishment of a population commission that defined the major outlines of Cameroon's population policy and its translation into national, regional, and sectorial development plans. The results obtained were evidence of the political will of high authorities and of the technical competence of planning staffs. The framework for planning of population, human resources, and development in Africa is intended to guide planners while being adaptable to the conditions, structures, and needs of each particular country. The 9-step framework begins with an inventory and evaluation of statistical data available for planning, followed by definitions of the overall orientation of national development and of sectorial, regional, and national objectives of the plan. The 4th step is a study of the interdependence between population and social and economic factors, followed by development of

    Background The extraction of the teeth by traditional healers in Cameroon is an established cultural practice in the central region of the Cameroon. Traditional healers (TH) use herbs and crude un-sterilized instruments and tools for the tooth extraction procedure. The present study investigates the knowledge and practices of traditional healers regarding tooth extraction and the management of its complications. Methods A cross sectional design utilizing semi-structured questionnaires was used to collect the data from traditional healers and their patients. Results Sixteen traditional healers (TH) were interviewed. All were male and the majority were between 25-35 years old. The most important reason given for the removal of a tooth was "if it has a hole". All reported using herbs to control bleeding and pain after extractions. Only 20% used gloves between patients when extracting a tooth and just over a third (31.3%) gave post-operative instructions. Eighty seven percent managed complications with herbs and 62.5% reported that they would refer their patients to a dentist whenever there are complications. Only a third (31.3%) was familiar with the basic anatomy of a tooth and more than half (56.3%) reported that tooth extractions are the only treatment for dental problems. One hundred and fifty patients were interviewed with a mean age of 29 years. More than two thirds were in the 21-30 year age group and just over half were male. Sixty six percent reported that they visited the TH because it is cheap, 93.3% were satisfied with the treatment they received while 95.3% reported said they never had a problem after an extraction. Conclusions Tooth extractions using medicinal plants is well established in Lekie division, Cameroon. Infection control during extraction is not the norm. Traditional healers are willing to co-operate with oral health workers in improving the oral health of their patients. Mutual cooperation, collaboration and integrating TH into primary oral

    Simian immunodeficiency virus (SIV) naturally infects two subspecies of chimpanzee: Pan troglodytes troglodytes from Central Africa (SIVcpzPtt) and P. t. schweinfurtii from East Africa (SIVcpzPts), but is absent in P. t. verus from West Africa and appears to be absent in P. t. ellioti inhabiting Nigeria and western Cameroon. One explanation for this pattern is that P. t. troglodytes and P. t schweinfurthii may have acquired SIVcpz after their divergence from P. t. verus and P. t. ellioti. However, all of the subspecies, except P. t. verus, still occasionally exchange migrants making the absence of SIVcpz in P. t. ellioti puzzling. Sampling of P. t. ellioti has been minimal to date, particularly along the banks of the Sanaga River, where its range abuts that of P. t. troglodytes. This study had three objectives. First, we extended the sampling of SIVcpz across the range of chimpanzees north of the Sanaga River to address whether under-sampling might account for the absence of evidence for SIVcpz infection in P. t. ellioti. Second, we investigated how environmental variation is associated with the spread and prevalence of SIVcpz in the two chimpanzee subspecies inhabiting Cameroon since environmental variation has been shown to contribute to their divergence from one another. Finally, we compared the prevalence and distribution of SIVcpz with that of Simian Foamy Virus (SFV) to examine the role of ecology and behavior in shaping the distribution of diseases in wild host populations. The dataset includes previously published results on SIVcpz infection and SFVcpz as well as newly collected data, and represents over 1000 chimpanzee fecal samples from 41 locations across Cameroon. Results revealed that none of the 181 P. t. ellioti fecal samples collected across the range of P. t. ellioti tested positive for SIVcpz.

    The persistent high prevalence of human scabies, especially in low- and middle-income countries prompted us to research the sociodemographic profile of patients suffering from it, and its spreading factors in Cameroon, a resource-poor setting. We conducted a cross-sectional survey from October 2011 to September 2012 in three hospitals located in Yaoundé, Cameroon, and enrolled patients diagnosed with human scabies during dermatologists' consultations who volunteered to take part in the study. We included 255 patients of whom 158 (62 %) were male. Age ranged from 0 to 80 years old with a median of 18 (Inter quartile range: 3-29) years. One to eight persons of our patients' entourage exhibited pruritus (mean = 2.1 ± 1.8). The number of persons per bed/room varied from 1 to 5 (mean = 2.1 ± 0.8). The first dermatologist's consultation occurred 4 to 720 days after the onset of symptoms (mean = 77.1 ± 63.7). The post-scabies pruritus (10.2 % of cases) was unrelated to the complications observed before correct treatment (all p values > 0.05), mainly impetiginization (7.1 %) and eczematization (5.9 %). Human scabies remains preponderant in our milieu. Populations should be educated on preventive measures in order to avoid this disease, and clinicians' knowledges must be strengthened for its proper diagnosis and management.

    Rotavirus is the most common cause of severe diarrheal disease in children under 5 years of age worldwide. The World Health Organization (WHO) estimated that 453,000 rotavirus-attributable deaths occur annually. Through the WHO, the Rotavirus Sentinel Surveillance Program was established in Cameroon in September 2007 with the Mother and Child Center (MCC) in Yaoundé playing the role of sentinel site and national laboratory for this program. The objectives of this surveillance were to assess the rotavirus disease burden and collect baseline information on rotavirus strains circulating in Cameroon. Diarrheal stool samples were collected in a pediatric hospital from children under 5, using the WHO case definition for rotavirus diarrhea. Antigen detection of rotavirus was performed by using an enzyme immunoassay (EIA). The genotypic characterization was performed using multiplexed semi-nested reverse transcription-polymerase chain reaction (RT-PCR) assays. Between September 2007 and December 2012, 2444 stool samples were received at the MCC laboratory for rotavirus antigen detection, of which 999 (41%) were EIA positive. Among EIA positive samples 898 were genotyped. Genotype prevalence varied each year. Genotype G9P[8] was the dominant type during 2007 (32%) and 2008 (24%), genotype G3P[6] predominated in 2010 (36%) and 2011 (25%), and G1P[8] was predominant in 2012 (44%). The findings showed that the rotavirus disease burden is high and there is a broad range of rotavirus strains circulating in Yaoundé. These data will help measure the impact of vaccination in the future.

    Evaluation of medication efficacy and safety is an essential guarantee to successful therapeutic outcome in public health practices. However, larger distribution chain supply in developing countries such as Cameroon is often challenged by counterfeit drugs, poor manufacturing, storage and degradation leading to health and patient adverse consequences. Yet, access to supply chain management in strengthening ARVs quality assurance and outcomes remains poorly documented. More than 53,000 patients have been enrolled on free ARVs medications, but little is documented on quality assurance and validity of safety for affected populations along the supply chain management since 2008. The cross sectional study was conducted in ARVs distribution units and centers in central, littoral and south west regions of Cameroon. ARVs drugs samples included Nevirapine, Efavirenz, and fixed dose combinations of Zidovudine + Lamivudine, Lamivudine + Stavudine and Zidovudine + Lamivudine + Nevirapine. Drugs packaging and labeling was assessed and galenic assays were performed at National Laboratory of quality Control of Medications and Expertise (LANACOME), Yaoundé, Cameroon. The study covered 16 structures located in eight different towns including the central ARVs store, two regional pharmaceutical procurement centers and thirteen HIV approved treatment centers and management units. A total of 35 ARVs products were collected. Only eight ARVs drugs containing Lamivudine and Stavudine presented with white stains on tablets, however these drugs were standard for all other tests performed. The others 28 ARVs products were standards to all assays performed. We concluded that ARVs drugs freely accessible and distributed to PLWHA are of good quality in Cameroon. However, with the increase number of patients under HAART since 2013, adoption of "Test and Treat" approach to reach the 90-90-90 goals and with the implementation of new national antiretroviral regimen guidelines and molecules

    Bamboo is a well know and versatile material, which is a common sight across Cameroon's diverse ecosystems, from dry to humid tropical and Afromontane forests. Its numerous uses range from storage jars to decorating restaurant-bars, beehives to knives, fences, fodder, and fuel. Responding to the paucity of data on species and uses, the value chain for bamboo in Cameroon was analyzed. Based on 171 interviews and field observations, two African indigenous species (alpine Yushania alpina and savannah Oxytenanthera abyssinica) and exotic (Bambusa vulgaris spp.) bamboos were identified as most utilized. They were tracked from major production zones to final consumers. The ecological, socio-economic, institutional, and governance contexts and impacts are described and analyzed. Issues for research, conservation, and development are highlighted. These include the ambiguous regulatory status, the relationship between tenure and management, threats and conservation of African species and options to increase the sustainable livelihoods for stakeholders dependent upon bamboo.

    Total Exploration Production Cameroon, a subsidiary of the Compagnie Francaise Des Petroles (CFP)/total has been operating since 1979 on the H 17 north concession shared by the CFP total/Mobil Association. On this concession, 3 high pressure wildcats were drilled but had to be abandoned due to lost circulation and kicks. None of these wildcats was drilled to the programed total depth, and no testing was performed. The target formations (Isongo sands) are located below thick zones of under-compacted shale (500 M and over). Many wells have had to be abandoned upon reaching these zones in Cameroon as well as in Nigeria, and the few wells where the shales were drilled were time consuming and costly (especially barite), with many drilling problems. Problems encountered are discussed as a guide to understanding the structures in this type of well.

    Two planned trials of pre-exposure prophylaxis tenofovir in Cambodia and Cameroon to prevent HIV infection in high-risk populations were closed due to activist pressure on host country governments. The international news media contributed substantially as the primary source of knowledge transfer regarding the trials. We aimed to characterize the nature of reporting, specifically focusing on the issues identified by media reports regarding each trial. With the aid of an information specialist, we searched 3 electronic media databases, 5 electronic medical databases and extensively searched the Internet. In addition we contacted stakeholder groups. We included media reports addressing the trial closures, the reasons for the trial closures, and who was interviewed. We extracted data using content analysis independently, in duplicate. We included 24 reports on the Cambodian trial closure and 13 reports on the Cameroon trial closure. One academic news account incorrectly reported that it was an HIV vaccine trial that closed early. The primary reasons cited for the Cambodian trial closure were: a lack of medical insurance for trial related injuries (71%); human rights considerations (71%); study protocol concerns (46%); general suspicions regarding trial location (37%) and inadequate prevention counseling (29%). The primary reasons cited for the Cameroon trial closure were: inadequate access to care for seroconverters (69%); participants not sufficiently informed of risks (69%); inadequate number of staff (46%); participants being exploited (46%) and an unethical study design (38%). Only 3/23 (13%) reports acknowledged interviewing research personnel regarding the Cambodian trial, while 4/13 (30.8%) reports interviewed researchers involved in the Cameroon trial. Our review indicates that the issues addressed and validity of the media reports of these trials is highly variable.

    The prevalence of epilepsy in Cameroon is higher than that of the industrialized world and other developing countries. Neurocysticercosis due to Taenia solium infestation has been reported as a major cause of epilepsy in some parts of Cameroon although there are some conflicting data. The prevalence of epilepsy is especially high in the Momo division of the North-West Province of Cameroon. We hypothesized that individuals with epilepsy in this region have a higher percentage of seropositivity to T. solium than matched controls. We conducted a case-control study in the Momo subdivision of Ngie. Individuals with epilepsy were recruited from the health centers in Ngie. Control subjects were selected from 19 Ngie villages. Potential cases of people with epilepsy (PWE) were identified through a questionnaire applied by trained field workers, using history of epileptic seizures as a key indicator. Blood samples were taken from all consenting individuals by finger prick, stored in StabilZyme Select, and assayed for antibodies to T. solium in an Atlanta based reference laboratory. We accrued 249 patients with epilepsy, of whom 237 met the inclusion criteria, and 245 age-matched controls. There was no significant difference in seropositivity to T. solium between those individuals with epilepsy (5%) and controls (4.9%). Our data do not support the hypothesis that epilepsy is associated with seropositivity to T. solium. It is highly unlikely that cysticercosis plays a causative role in the high prevalence of epilepsy in this region of Cameroon. Copyright © 2013 British Epilepsy Association.

    Recent blue-ribbon panel reports have concluded that HIV treatment programs in less wealthy countries must integrate mental health identification and treatment into normal HIV clinical care and that research on mental health and HIV in these settings should be a high priority. We assessed the epidemiology of depression in HIV patients on antiretroviral therapy in a small urban setting in Cameroon by administering a structured interview for depression to 400 patients consecutively attending the Bamenda Regional Hospital AIDS Treatment Center. One in five participants met lifetime criteria for MDD, and 7% had MDD within the prior year. Only 33% had ever spoken with a health professional about depression, and 12% reported ever having received depression treatment that was helpful or effective. Over 2/3 with past-year MDD had severe or very severe episodes. The number of prior depressive episodes and the number of HIV symptoms were the strongest predictors of past-year MDD. The prevalence of MDD in Cameroon is as high as that of other HIV-associated conditions, such as tuberculosis and Hepatitis B virus, whose care is incorporated into World Health Organization guidelines. The management of depression needs to be incorporated in HIV-care guidelines in Cameroon and other similar settings. PMID:22860006

    Results of the chemical and isotopic analysis of the water and gases discharged from volcanic crater lakes and soda springs located along the Cameroon Volcanic Line were used to characterize and infer their genetic relationships. Variations in the solute compositions of the waters indicate the dominant influence of silicate hydrolysis. Na + (40-95%) constitutes the major cation in the springs while Fe 2+ + Mg 2+ (70%) dominate in the CO 2-rich lakes. The principal anion is HCO 3 (>90%), except in the coastal springs where Cl-predominates. Lakes Nyos and Monoun have FeMgCaHCO 3- type signatures; the soda springs are essentially NaHCO 3- type, while all other lakes show similar ionic compositions to dilute surface waters. Dissolved gases show essentially CO 2 (>90%), with small amounts of Ar and N 2, while CH 4 constitutes the principal component in the non-gassy lakes. Active volcanic gases are generally absent, except in the Lobe spring with detectable H 2S. Stable isotope ratio evidence indicates that the bicarbonate waters are essentially of meteoric origin. CO 2 ( δ13C = -2 to -8% 0 and He ( 3He/ 4He = 1 to 5.6R a) infer a mantle contribution to the total CO 2. CH 4 has a biogenic source, while Ar and N 2 are essentially atmospheric in origin, but mixing is quite common.

    To examine the association between intimate partner violence (IPV; physical, sexual, and emotional violence) and induced abortion in Cameroon. We used data from the 2004 Cameroon Demographic Health Survey (DHS) and hierarchic multivariate modeling to compare the rates of induced abortion by IPV type. In 2004, 2570 women were administered the domestic violence module of the DHS. Of those women, 126 (4.9%) reported having had at least 1 induced abortion. Cameroonian women reported high rates of IPV: physical violence (995 [38.7%]); emotional violence (789 [30.7%]); and sexual violence (381 [14.8%]). After adjusting for covariates, physical and sexual IPV increased the risk for induced abortion, whereas the association between emotional violence and induced abortion was not significant in multivariate models. Given the increased risk for maternal morbidity and mortality following unsafe induced abortions in Cameroon, the association between induced abortion and IPV is of interest in terms of public health. Programs targeted at preventing IPV might reduce the rate of maternal morbidity and mortality. Copyright © 2010 International Federation of Gynecology and Obstetrics.

    Dinosaur trackways have rarely been reported in Cretaceous strata across the African continent. To the exception of ichnological occurrences in Morocco, Tunisia, Niger and Cameroon, our knowledge on the composition of Cretaceous dinosaur faunas mostly relies on skeletal evidence. For the first time, we document several dinosaur trackways from the Cretaceous of the Mamfe Basin in western Cameroon. Small and medium-size tridactyl footprints as well as numerous large circular footprints are present on a single horizon showing mudcracks and ripple marks. The age of the locality is considered Cenomanian-Turonian and if confirmed, this ichnological assemblage could be younger than the dinosaur footprints reported from northern Cameroon, and coeval with or younger than skeletal remains reported from the Saharan region. These trackways were left in an adjacent subsiding basin along the southern shore of the Benue Trough during a time of high-sea stand when the Trans-Saharan Seaway was already disconnecting West Africa from the rest of the continent. We predict that other similar track sites may be occurring along the margin of the Benue Trough and may eventually permit to test hypotheses related to provincialism among African dinosaur faunas.

    Background. The cholera burden in Cameroon has increased during the past 2 decades. During 2010 and 2011, the largest number of cholera cases in Cameroon since February 1971 were reported. This article describes cholera outbreaks during 2010-2011. Methods. Data received from the national surveillance system from 2010 and 2011 were compiled and analyzed. Results. The first suspected cholera cases were reported in the Far North region on 6 May 2010. In 2010, 10 759 cholera cases were reported by 8 of the 10 regions in the country, with 657 deaths (case-fatality ratio [CFR], 6.1%). In 2011, through September 22, 17 121 suspected cholera cases, including 636 deaths (CFR, 3.7%), were reported all over the country. During 2010, the Far North region accounted for 87.6% of cases (9421/10 759) and 91.6% of deaths (602/657) recorded. By contrast, during 2011, 5 regions (Far North, North, Center, Southwest, and Littoral) accounted for 90.6% of cases (15 511/17 121) and 84.0% of deaths recorded. Vibrio cholerae was identified in 525 stool specimens, and all organisms were serogroup O1. Conclusions. The ongoing cholera outbreak in Cameroon increased in intensity and geographic spread from 2010 to 2011. Nevertheless, the overall CFR decreased during this period. Strengthening the early warning system and enhancing water, sanitation, and hygiene interventions and sensitization should be considered in addressing cholera outbreaks.

    A nationwide survey for snail hosts of human schistosomes was carried out in Cameroon between 1985 and 1988. In total, 668 sites at 432 locations were sampled. In the arid, northern half of the country (tropical climatic zone), where both intestinal and urinary schistosomiasis are hyperendemic, Biomphalaria pfeifferi was the only Schistosoma mansoni host and Bulinus globusus and B. senegalensis the most common S. haematobium hosts. In that region, these snails occurred almost exclusively in temporary bodies of water. Taking into account results from a companion study on the distribution of schistosomiasis in humans, our results clearly show that temporary water bodies in the tropical zone are the principal foci of transmission. These findings disagree with commonly held views about schistosome transmission in Cameroon. B. truncatus, a S. haematobium host, was also present in the tropical zone but was found principally in perennial habitats. Although some perennial habitats were important transmission sites, they represent only a small portion of the overall problem. B. truncatus is the principal S. haematobium host in the wetter southern half of the country where schistosomiasis haematobium is highly focal. Biom. camerunensis was far more common than Biom. pfeifferi in the South but did not occur where S. mansoni prevalence rates were high; thus it appears to be a poor host. B. forskalii, the sole host of S. intercalatum in Cameroon, occurs widely throughout the country; however, the schistosome is restricted to a small region in the South.

    Inappropriate antibiotic prescribing, common in India, contributes to increased risk for development of bacterial resistance. Patients admitted to intensive care units (ICUs) are often prescribed antibiotics. Paucity of local data on antibiotic prescribing hinders development of appropriate interventions. The aim of the study was to describe and compare antibiotic prescribing in medical ICUs (MICUs) at two private sector hospitals, one teaching (TH) and one non-teaching (NTH) in Ujjain, India. The study was conducted prospectively for 3 years at MICUs of both hospitals. Patients were compared for demographic variables and diagnosis, prescribed antibiotics, generic name prescribing, and route of administration. Adherence to the World Health Organization list of essential medicines (WHOLEM) and the National List of Essential Medicines of India (NLEMI) was analyzed. In total, 4843 of 6141 patients admitted to the MICUs stayed at least one night. More than 70% were prescribed antibiotics. Generic name prescribing was more common at the TH than at the NTH. Prescriptions at the TH had higher compliance to WHOLEM and NLEMI compared with that at the NTH (p < 0.001). Of the 1371 patients at the TH, 189 (14%) and of 3472 at the NTH, 400 (12%) patients were diagnosed with infections. More than 75% of patients at both hospitals had no infection-associated diagnoses. Antibiotic prescribing was common at both hospitals. The antibiotic prescriptions at the TH had higher compliance to WHOLEM and NLEMI. However, there is a need to develop appropriate interventions to improve antibiotic prescribing at both hospitals.

    Background Health care providers are at risk of acquiring human immunodeficiency virus (HIV) infection from occupational exposure, with nurses being the most vulnerable. There is no data on the awareness of post-exposure prophylaxis (PEP) among nurses in Cameroon. This study aimed to assess the knowledge, practices of nurses regarding PEP for HIV and their determinants in Cameroon. Methods A cross-sectional study was conducted between April and July 2013, and involved 80 nurses in a rural health district in the North West Region of Cameroon. Data was collected using a structured questionnaire and analysed using the SPSS software version 20. Results In all, 73.7% of the participants had poor knowledge about PEP for HIV. Though many (83.8%) had heard about PEP, just 10 (12.5%) had received formal training on PEP for HIV. Only 24 (30%) and 20 (25%) knew the correct drug regimen and duration of treatment respectively. The majority (85%) considered themselves to be at risk of acquiring HIV at work, with 54 (67.5%) having experienced an exposure in the past, mainly while setting up intravenous lines (57.4%), recapping needles (37.0%) and during delivery (24.1%). Of those exposed, ten (18.9%) received PEP, which was started after 24 hours in 50%. In multivariable regression analyses, awareness of hospital policy [OR: 0.043 (0.005–0.404), p-value = 0.006] was associated with Good knowledge on PEP for HIV. Conclusions The knowledge and practice of nurses on PEP for HIV in Cameroon is low. There is urgent need for training programmes and workshops to increase awareness, improve practice, and reduce the risk of HIV acquisition from work related activities among health care providers.

    Seventy-one patients with malodorous, painful wounds were treated with sugar dressings in Lilongwe Hospital, Malawi, to assess the effects of such dressings on diminishing pain and odour. Pain and odour were assessed at the beginning of dressing application and then at frequent intervals. Mean patient odour scores reduced from 5.45 (out of 10) on application to 2.94 at 10 days, and mean patient discomfort scores reduced from 6.73 on application to 3.87 at 10 days. This very cheap treatment produced reproducible benefits as part of an appropriate protocol for use in developing world hospitals with limited resources and nursing care.

    Background. In rural Africa, data on virologic effectiveness of antiretroviral treatment (ART) are not sufficient to assess the gap with the UNAIDS 90-90-90 treatment targets. We investigated the prevalences of unsuppressed viral load and antiretroviral drug resistance and the profile of genotypic resistance mutations among patients routinely treated in rural Cameroon. Methods. A cross-sectional study was performed in 2013–2014 among patients ≥15 years and on first-line ART for ≥6 months in a district hospital. Patients were offered free access to human immunodeficiency virus viral load testing. Genotypic drug resistance testing was done when the viral load was >1000 copies/mL. Multivariate logistic regression models were used to assess the relationship of unsuppressed viral load or antiretroviral drug resistance with sociodemographic and medical characteristics. Results. Of 407 patients (women 74.9%, median age 41.8 years, median time on ART 29.2 months), 96 (23.6%; 95% confidence interval [CI], 19.5–28.0) had unsuppressed viral load and 74 (18.2%; 95% CI, 14.6–22.3) had antiretroviral drug resistance. The prevalences of unsuppressed viral load and resistance increased with time on ART, from 12.0% and 8.0% in the 6- to 12-month group to 31.3% and 27.1% in the >72-month group, respectively. All 74 patients with antiretroviral drug resistance were resistant to nonnucleoside reverse-transcriptase inhibitors, and 57 of them were also resistant to nucleoside reverse-transcriptase inhibitors.

    In rural Africa, data on virologic effectiveness of antiretroviral treatment (ART) are not sufficient to assess the gap with the UNAIDS 90-90-90 treatment targets. We investigated the prevalences of unsuppressed viral load and antiretroviral drug resistance and the profile of genotypic resistance mutations among patients routinely treated in rural Cameroon. A cross-sectional study was performed in 2013-2014 among patients ≥15 years and on first-line ART for ≥6 months in a district hospital. Patients were offered free access to human immunodeficiency virus viral load testing. Genotypic drug resistance testing was done when the viral load was >1000 copies/mL. Multivariate logistic regression models were used to assess the relationship of unsuppressed viral load or antiretroviral drug resistance with sociodemographic and medical characteristics. Of 407 patients (women 74.9%, median age 41.8 years, median time on ART 29.2 months), 96 (23.6%; 95% confidence interval [CI], 19.5-28.0) had unsuppressed viral load and 74 (18.2%; 95% CI, 14.6-22.3) had antiretroviral drug resistance. The prevalences of unsuppressed viral load and resistance increased with time on ART, from 12.0% and 8.0% in the 6- to 12-month group to 31.3% and 27.1% in the >72-month group, respectively. All 74 patients with antiretroviral drug resistance were resistant to nonnucleoside reverse-transcriptase inhibitors, and 57 of them were also resistant to nucleoside reverse-transcriptase inhibitors. Our estimations were among the highest observed in the west and central African region. The proportion of patients with virologic failure should be divided at least by 2 to reach the UNAIDS 90-90-90 treatment targets.

    Begomovirus isolates ToF3B2 and ToF3B17 and betasatellite isolate SatBToF3 were obtained from the same infected tomato plant showing begomovirus disease symptoms in Fontem, Cameroon. The full-length nucleotide sequences of ToF3B2, ToF3B17 and SatBToF3 were cloned and sequenced and were determined to be 2,797 nt, 2,794 and 1,373 nt long respectively. When compared with other begomovirus and betasatellite sequences, ToF3B2 was 93.5 % identical to Tomato leaf curl Togo virus, ToF3B17 was 95 % identical to Tomato leaf curl Cameroon virus and SatBToF3 was 92 % identical to Ageratum leaf curl Cameroon betasatellite (ALCCMB), respectively. The identification of ALCCMB in Ageratum and now in tomato strongly suggests Ageratum may be an alternative host to these viruses and that ALCCMB is non host specific and may cause severe diseases when transmitted to other crops.

    With funds from Elizabeth Glaser Pediatric AIDS Foundation, the Cameroon Baptist Convention Health Board implemented a program to prevent mother-to-child transmission of HIV-1 (PMTCT) as part of its routine antenatal care, with single-dose maternal and infant peripartum nevirapine (NVP) prophylaxis of HIV-positive mothers and their babies. Nurses, midwives, nurse aides, and trained birth attendants counseled pregnant women, obtained risk factor data, and offered free HIV testing with same-day results. From February 2000 through December 2004, this program rapidly expanded to 115 facilities in 6 of Cameroon's 10 provinces, not only to large hospitals but to remote health centers staffed by trained birth attendants. We trained 690 health workers in PMTCT and counseled 68,635 women, 91.9% of whom accepted HIV testing. Of 63,094 women tested, 8.7% were HIV-1-positive. Independent risk factors for HIV-1 infection included young age at first sexual intercourse, multiple sex partners, and positive syphilis serology (P < 0.001 for each). We counseled 98.7% of positive and negative mothers on a posttest basis. Of 5550 HIV-positive mothers, we counseled 5433 (97.9%) on single-dose NVP prophylaxis. Consistent training and programmatic support contributed to rapid upscaling and high uptake and counseling rates.

    Introduction. Urethral strictures in boys denote narrowing of the urethra which can be congenital or acquired. In case of acquired strictures, the etiology is iatrogenic or traumatic and rarely infectious or inflammatory. The aim of this study was to highlight the diagnostic and therapeutic difficulties of acquired nontraumatic urethral strictures in boys in Yaoundé, Cameroon. Methodology. The authors report five cases of nontraumatic urethral strictures managed at the Pediatric Surgery Department of the YGOPH over a two-year period (November 2012–November 2014). In order to confirm the diagnosis of urethral stricture, all patients were assessed with both cystourethrography and urethrocystoscopy. Results. In all the cases the urethra was inflammatory with either a single or multiple strictures. The surgical management included internal urethrotomy (n = 1), urethral dilatation (n = 1), vesicostomy (n = 2), and urethral catheterization (n = 3). With a median follow-up of 8.2 months (4–16 months) all patients remained symptoms-free. Conclusion. The authors report the difficulties encountered in the diagnosis and management of nontraumatic urethral strictures in boys at a tertiary hospital in Yaoundé, Cameroon. The existence of an inflammatory etiology of urethral strictures in boys deserves to be considered. PMID:27239364

    Background Zonocerus variegatus (Linnaeus, 1758) (Orthoptera: Pyrgomorphidae) is known as an agricultural pest in West and Central Africa. However, its importance in the agricultural production system in Cameroon has not been investigated. The study assesses farmers' perception on the importance of Z. variegatus in the agricultural production systems of the humid forest zone of Southern Cameroon. Methods Research was carried out in 5 villages of each of three Agro-Ecological, Cultural and Demographic Blocks (AECD-Blocks) of the Forest Margin Benchmark Area (FMBA). In each village, a semi-structured survey was used; male and female groups of farmers were interviewed separately. Results Z. variegatus is present throughout the humid forest zone of Southern Cameroon, where it is ranked as the third most economically important insect pest of agriculture. In the farmers' opinion, Z. variegatus is a polyphagous insect with little impact on young perennial crops. The length of the pre-farming fallow does not affect Z. variegatus pest pressure in the following crops. The increased impact of the grasshopper observed today in the fields, compared to what existed 10 years ago is as a result of deforestation and increase in surface of herbaceous fallow. The damage caused by Z. variegatus is higher in fields adjacent to C. odorata and herbaceous fallows than in those adjacent to forests and shrubby fallows. The fight against this grasshopper is often done through physical methods carried out by hand, for human consumption. The farmers highlight low usage of the chemical methods and a total absence of biological and ecological methods. Conclusion Farmers' perception have contributed to understanding the status of Z. variegatus in the humid forest zone of Southern Cameroon. The results are in general similar to those obtained in other countries. PMID:16573815

    Enteroviruses (EVs) infecting African Non-Human Primates (NHP) are still poorly documented. This study was designed to characterize the genetic diversity of EVs among captive and wild NHP in Cameroon and to compare this diversity with that found in humans. Stool specimens were collected in April 2008 in NHP housed in sanctuaries in Yaounde and neighborhoods. Moreover, stool specimens collected from wild NHP from June 2006 to October 2008 in the southern rain forest of Cameroon were considered. RNAs purified directly from stool samples were screened for EVs using a sensitive RT-nested PCR targeting the VP1 capsid coding gene whose nucleotide sequence was used for molecular typing. Captive chimpanzees (Pan troglodytes) and gorillas (Gorilla gorilla) were primarily infected by EV types already reported in humans in Cameroon and elsewhere: Coxsackievirus A13 and A24, Echovirus 15 and 29, and EV-B82. Moreover EV-A119, a novel virus type recently described in humans in central and west Africa, was also found in a captive Chimpanzee. EV-A76, which is a widespread virus in humans, was identified in wild chimpanzees, thus suggesting its adaptation and parallel circulation in human and NHP populations in Cameroon. Interestingly, some EVs harbored by wild NHP were genetically distinct from all existing types and were thus assigned as new types. One chimpanzee-derived virus was tentatively assigned as EV-J121 in the EV-J species. In addition, two EVs from wild monkeys provisionally registered as EV-122 and EV-123 were found to belong to a candidate new species. Overall, this study indicates that the genetic diversity of EVs among NHP is more important than previously known and could be the source of future new emerging human viral diseases. PMID:25079078

    There is a huge need for health research to support contextually relevant health service and policy solutions to better the health of populations in sub-Saharan Africa. This need contrasts with the very timid engagement of healthcare practitioners in research in the region.It is against this background that the Douala General Hospital (a tertiary-care hospital in Cameroon), under the stewardship of its chief executive officer, organised the first annual scientific and research day in October 2014. This maiden event saw the participation of local research leaders and the eminent director of the South African Hatter Institute for Cardiovascular Research in Africa, who co-chaired the event. The aim was to educate students, clinicians and junior researchers on the importance of clinical research and evidence-based medicine around the leading theme of the event: action for clinical research and good medical practice.Several abstracts were presented, covering various aspects of medicine, including cardiology, rheumatology, paediatrics, pulmonology, HIV medicine, and obstetrics and gynaecology, together with key lectures on cardiac disease and pregnancy, and plenary sessions on research methodology, scientific writing and publishing. It is hoped that this event will enhance clinical research and the dissemination of research findings to improve evidence-based clinical practice in the country.

    The Fomopéa pluton (622-613 Ma) is located in the western part of the Pan-African belt in Cameroon. It comprises of 3 units: biotite-hornblende granitoids (BHG), biotite monzogranites (BmG) and edenite syenogranites (EsG). The BHG unit displays magnetic fabrics characterized by foliations gently dipping towards the ESE and ENE-trending lineations (D1 event). Microstructures are magmatic to submagmatic. In discrete N-S deformation bands (D2), lineations are rotated towards the North and microstructures indicate solid-state deformation at mid- to low-T conditions, with kinematic indicators pointing to a sinistral motion. The second unit, BmG, displays lineation trajectories suggesting emplacement during the D2 event. The EsG unit displays fabrics consistent with a later emplacement, with no superposed deformation. The last event (D3) corresponds to a dextral shear zone, that runs along the southeastern border of the Fomopéa pluton. It was responsible for protomylonitic deformation of the granitic rocks in greenschist facies conditions, whereas the core of the shear zone registered higher temperatures and strain. This shear zone induced a rejuvenation of the Rb/Sr isotopic system in the pluton at ca 572 Ma. It belongs to the Central Cameroon shear zone system, regarded as the prolongation of the dextral Patos shear zone system in Brazil.

    The laboratory tests supplied by clinical laboratory comprise an increasing volume in most hospitals. Consultation and effective utilization of laboratory data are important aspects of evidence-based medicine. Effective utilization of laboratory data will also contribute to the efficiency of hospital practice. Questionnaire surveys were conducted to investigate the actual situation in the information office of clinical laboratories in national, public and private facilities of 80 medical universities in Japan. Few facilities demonstrated efficient functioning, although information offices had been opened in six national, one public, and four private universities. The office staff received many questions on specimen handling and analytical methods. In the future, the office will be expected to be actively involved in mutual communications with clinical physicians and an information system such as computerized web is anticipated. Furthermore, a full-time laboratory physician and technicians are expected to provide support as experts in patient diagnosis.

As inclusion criteria, patients who had routine visit in 3 month continuously with fasting plasma glucose (GDN) < or = 126 mg/dl was participated as a well glycemic control group, and the one with GDN > 126 mg/dl as poor glycemic control group. Data were recorded which included age, sex, period of DM, daily diet pattern, and education received. we found that glycemic control was not affected by sex (p=0.52) and age (p=0.38), but it was affected by period of DM (p=0.02). Glycemic control in the present study was affected by dietary pattern (p=0.01), but not by education (p=1.00). the present study has found significant correlation between regulation of dietary pattern and glycemic control (p=0.01).

    This study was done to describe the incidence and outcomes of primary hospital-acquired bloodstream infection (HABSI) secondary to Staphylococcus aureus (SA) that did and did not meet the National Healthcare Safety Network's (NHSN's) definition for central line-associated bloodstream infection (CLABSI). Consecutive hospitalized patients during a 48-month study period with an SA HABSI were categorized according to those who did and did not meet the NHSN's definitions for CLABSI and non-CLABSI. Primary outcomes were mortality at 30 days and 1 year. Secondary outcomes were the incidence of complicated bacteremia and the need for operative intervention secondary to the HABSI event. A total of 122 episodes of primary SA HABSIs were identified: 78 (64%) were CLABSIs, and 44 (36%) were non-CLABSIs. Overall 30-day and 1-year mortality in the cohort was 21.3% and 38.5%, respectively, and did not differ significantly between the 2 groups. Complicated SA HABSI was significantly more common in the non-CLABSI group (15.9% [n = 7] vs 0% [n = 0], P ≤ .001). Primary SA HABSI was associated with significant 30-day and 1-year mortality. Complications from SA non-CLABSI requiring surgical intervention were significantly more common than in those with a CLABSI event. Our findings affirm the significance of non-device-related hospital-acquired infections. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

    Peripherally inserted central catheters (PICCs) are commonly used for delivering intravenous therapy. PICC failure is unacceptably high (up to 40%) due to mechanical, infectious and thrombotic complications. Poor securement potentiates all complication types. This randomised controlled trial (RCT) aimed to examine the feasibility of a large RCT of four dressing and securement methods to prevent PICC failure. This single-centre pilot RCT included 124 admitted medical/surgical/cancer patients aged ≥ 16 years with a PICC. Interventions were: (i) standard polyurethane dressing and sutureless securement device (SPU + SSD, control); (ii) polyurethane with absorbent lattice pad dressing (PAL + Tape); (iii) combination securement-dressing (CSD); and (iv) tissue adhesive (TA + SPU). All groups except TA + SPU had a chlorhexidine-gluconate (CHG) impregnated disc. Feasibility outcomes were recruitment and safety/acceptability of the interventions. The primary outcome was PICC failure, a composite of PICC removal for local infection, catheter-associated bloodstream infection, dislodgement, occlusion, and/or catheter fracture. Secondary outcomes included individual complications, dressing failure and dwell time, PICC dwell time, skin complications/phlebitis indicators, product costs, and patient and staff satisfaction. Qualitative feedback was also collected. PICC failure incidence was: PAL + CHG + Tape (1/5; 20%; 17.4/1000 days), SPU + SSD + CHG (control) (4/39; 10%; 9.0/1000 days), TA + SPU (3/35; 9%; 9.6/1000 days), and CSD + CHG (3/42; 7%; 9.4/1000 days). Recruitment to PAL + CHG + Tape was ceased after five participants due to concerns of PICC dislodgement when removing the dressing. CSD + CHG, TA + SPU (TA applied only at PICC insertion time), and control treatments were acceptable to patients and health professionals. A large RCT of CSD + CHG and TA + SPU (but not PAL

    Ageratum conyzoides (goat weed) is a widespread uncultivated species in Cameroon that exhibits leaf curl disease (LCD) symptoms suggestive of begomovirus infection. In Asia, different begomovirus-satellite complexes have been identified in A. conyzoides. The objective of this study was to determine the identity of the suspect begomoviruses and their associated satellites in A. conyzoides in Cameroon. The results indicated that all three symptomatic A. conyzoides plants examined were infected with a new begomovirus species, herein named Ageratum leaf curl Cameroon virus (ALCCMV). The ALCCMV genome sequences shared their highest identity, at 84.3-88.5%, with a group of tomato-infecting begomoviruses from West Africa. In addition, a betasatellite and an alphasatellite were cloned from the same symptomatic A. conyzoides plants. The betasatellite sequences shared limited sequence identity at 37% or less with the betasatellite Cotton leaf curl Gezira betasatellite, and the new betasatellite species is herein named Ageratum leaf curl Cameroon betasatellite (ALCCMB). The alphasatellite shared 80% nt identity with Tomato leaf curl Cameroon alphasatellite (ToLCCMA), and the new alphasatellite species is herein named Ageratum leaf curl Cameroon alphasatellite (ALCCMA). In addition, two fragments containing begomovirus-alphasatellite sequences were cloned from sample AGLI4, and they were related to the defecting interfering molecule (Y14167) associated with Ageratum yellow vein virus from Asia. These results suggest that the begomoviral-satellite complexes infecting A. conyzoides in Cameroon may be as complex or more so, to species and strains reported thus far from Asia.

    The Numba ductile deformation zone (NDDZ) is characterised by folds recorded during the three deformation phases that affected the banded amphibole gneiss. Fold-shape analyses using the program Fold Profiler with the aim to show the importance of folding events in the structural analysis of the NDDZ and its contribution to the Pan-African orogeny in central Africa have been made. Classical field method, conic sections method and Ramsay's fold classification method were applied to (i) have the general orientation of folds, (ii) analyze the fold shapes and (iii) classify the geometry of the folded bands. Fold axes in banded amphibole gneiss plunge moderately (<15°) towards the NNE or SSW. The morphology of F1, F2 and F3 folds in the study area clearly points to (i) Z-shape folds with SE vergence and (ii) a dextral sense of shear motion. Conic section method reveals two dominant families: F1 and F3 folds belong to parabolic shape folds, while F2 folds belong to parabolic shape and hyperbolic shape folds. Ramsay's scheme emphasizes class 1C (for F1, F2 and F3 folds) and class 3 (for F2 folds) as main fold classes. The co-existence of the various fold shapes can be explained by (i) the structuration of the banded gneiss, (ii) the folding mechanisms that associate shear with a non-least compressive or flattening component in a ductile shear zone and (iii) the change in rheological properties of the band during the period of fold formation. These data allow us to conclude that the Numba region underwent ductile dextral shear and can be integrated (i) in a correlation model with the Central Cameroon Shear Zone (CCSZ) and associated syn-kinematic intrusions and (ii) into the tectonic model of Pan-African belt of central Africa in Cameroon.

    The progress of women in science has been widely discussed in recent years. Women have made great progress in the social sciences, but they lag in the field of physics. A survey of the situation of women in physics in Cameroon over the last three years shows some improvement and some areas of stagnation. For example, the statistics show an increase of women teaching physics in secondary school and a slight improvement in the numbers of women studying physics at the university level, but stagnation in the number of women lecturers in physics.

    The 2004 Demographic and Health Survey (DHS) in Cameroon revealed a higher prevalence of HIV in richest and most educated people than their poorest and least educated compatriots. It is not certain whether the higher prevalence results partly or wholly from wealthier people adopting more unsafe sexual behaviours, surviving longer due to greater access to treatment and care, or being exposed to unsafe injections or other HIV risk factors. As unsafe sex is currently believed to be the main driver of the HIV epidemic in sub-Saharan Africa, we designed this study to examine the association between wealth and sexual behaviour in Cameroon. We analysed data from 4409 sexually active men aged 15-59 years who participated in the Cameroon DHS using logistic regression models, and have reported odds ratios (OR) with confidence intervals (CI). When we controlled for the potential confounding effects of marital status, place of residence, religion and age, men in the richest third of the population were less likely to have used a condom in the last sex with a non-spousal non-cohabiting partner (OR 0.43, 95% CI 0.32-0.56) and more likely to have had at least two concurrent sex partners in the last 12 months (OR 1.38, 95% CI 1.12-1.19) and more than five lifetime sex partners (OR 1.97, 95% CI 1.60-2.43). However, there was no difference between the richest and poorest men in the purchase of sexual services. Regarding education, men with secondary or higher education were less likely to have used a condom in the last sex with a non-spousal non-cohabiting partner (OR 0.24, 95% CI 0.16-0.38) and more likely to have started sexual activity at age 17 years or less (OR 2.73, 95% CI 2.10-3.56) and had more than five lifetime sexual partners (OR 2.59, 95% CI 2.02-3.31). There was no significant association between education and multiple concurrent sexual partnerships in the last 12 months or purchase of sexual services. Wealthy men in Cameroon are more likely to start sexual activity

The 1998 Cameroon Demographic and Health Survey and the 2000 Multiple Indicator Cluster Survey are the main sources of household-level data. These surveys are supplemented by data from a 2002 survey of health facilities conducted in three provinces. At the national level, immunization financing data were collected from the Ministry of Health and donors that support the national Expanded Programme on Immunization. FINDINGS: The 1998 survey found that nationally 37% of children were fully immunized; the 2000 survey found that nationally 34% were fully immunized. These results are strongly correlated with both the mother's level of education and the household's economic status. Multilevel logistic regression shows that maternal education level is a stronger predictor of positive immunization status than is relative economic status. Children of mothers with secondary education or higher education were 3 times more likely to be fully vaccinated than children whose mothers had not completed primary education. At the health-facility level, both having art immunization plan and regular supervisory visits from someone at the health-district level are strongly positively associated with immunization rates. The cost of routine vaccinations for each fully immunized child is 12.73 U.S. dollars when donors' contributions are included but not the costs of immunization campaigns. CONCLUSION: Studies conducted in the 1980s and 1990s found that costs per fully immunized child varied from 2.19 U.S. dollars to 26.59 U.S. dollars (not adjusted for inflation) in a range of low-income and middle-income countries. The relatively low rates of immunization coverage in Cameroon, and the strong influence of

    Women are at a higher risk of being sexually harassed. There is a need to document the clinical findings of this crime and its outcome in order to improve the quality of care the victims receive. Case notes of patients who presented with alleged rape at Jos University Teaching Hospital between January 2001 and December 2003 were retrieved and analyzed. During the study period, 2,135 patients were seen in the Gynaecological Emergency Unit. A total of 120 were for alleged rape, representing 5.6% of the total cases seen. However, only 105 case notes were available for analysis. Of these, 63.8% of the alleged rapes were in children, with the infantile age group accounting for 26.7%. 36.2% of the victims had experienced some form of sexual exposure prior to the rape. A previous relationship with the rapist was established in 77.4% of the cases. Most cases delayed in presenting to hospital. Thirty six percent of the cases did not have a human immunodeficiency virus screening test done. Candida albicans (13.3%) accounted for most of the infectious agents. Emergency contraception was administered to the victims when indicated. Women under 16 years of age were at an increased risk of being raped, possibly because they are defenseless and vulnerable. Three quarters (3/4) of the assailants had some form of relationship with the victims, which may account for the delays in reporting. Children and young adolescents were more at risk than adults to be raped.

    Peripherally inserted central catheters (PICCs) are expected to be convenient and reliable venous access devices. The purpose of this study was to analyze clinical nurse specialist (CNS)-led PICC placement and to describe its growth in a tertiary hospital. A computerized database identified 3508 patients who had PICCs placed between November 2001 and June 2010. One thousand, eight hundred ninety-eight of the 4101 PICCs were available for complete follow-up, and 791 of 1898 PICCs were still in place. The mean dwell time of 1898 PICCs was 27.4 days (1∼422 days). Most PICCs were removed after the completion of infusion therapy; the remainder were removed following death, occlusion, suspected infection, or phlebitis, or were removed by the patient. The study found that CNS-led PICC placement for infusion therapies was effective and safe with relatively low complication rates and that CNSs played important roles in the increased use of PICCs.

    Background In Sub-Saharan Africa, infectious diarrhea is a major cause of morbidity and mortality. A case-control study was conducted to identify the etiology of diarrhea and to describe its main epidemiologic risk factors among hospitalized children under five years old in Bangui, Central African Republic. Methods All consecutive children under five years old hospitalized for diarrhea in the Pediatric Complex of Bangui for whom a parent’s written consent was provided were included. Controls matched by age, sex and neighborhood of residence of each case were included. For both cases and controls, demographic, socio-economic and anthropometric data were recorded. Stool samples were collected to identify enteropathogens at enrollment. Clinical examination data and blood samples were collected only for cases. Results A total of 333 cases and 333 controls was recruited between December 2011 and November 2013. The mean age of cases was 12.9 months, and 56% were male. The mean delay between the onset of first symptoms and hospital admission was 3.7 days. Blood was detected in 5% of stool samples from cases. Cases were significantly more severely or moderately malnourished than controls. One of the sought-for pathogens was identified in 78% and 40% of cases and controls, respectively. Most attributable cases of hospitalized diarrhea were due to rotavirus, with an attributable fraction of 39%. Four other pathogens were associated with hospitalized diarrhea: Shigella/EIEC, Cryptosporidium parvum/hominis, astrovirus and norovirus with attributable fraction of 9%, 10%, 7% and 7% respectively. Giardia intestinalis was found in more controls than cases, with a protective fraction of 6%. Conclusions Rotavirus, norovirus, astrovirus, Shigella/EIEC, Cryptosporidium parvum/hominis were found to be positively associated with severe diarrhea: while Giardia intestinalis was found negatively associated. Most attributable episodes of severe diarrhea were associated with rotavirus

    To reduce the prevalence of reproductive health problems among adolescents, governmental and nongovernmental organizations in Cameroon are implementing youth-oriented reproductive health programs. To facilitate the design of effective programs to increase condom use, this study examines survey data on the determinants of having ever used condoms and on current condom use with regular and casual partners among unmarried young people in urban Cameroon. While most adolescents have tried condoms at least once, use remains inconsistent. Parental support, personal risk perception, and self-efficacy are found to be associated with higher levels of condom use. Youth-oriented programs seeking to increase the number of new condom users among the young should promote parental support for condom use and enhance young people's perceptions of personal risk. Programs that work to convince the young that their sexual history can put them at risk of HIV infection and that dispel the myth that HIV risk with regular partners is low may serve to increase personal risk perception. Finally, communications programs should aim to increase adolescents' self-efficacy, particularly in terms of their perceived ability to convince partners to use condoms and to use them correctly.

    At a time when much energy is being spent all over the world to bring women into the fast-developing world of science, it is regrettable that these efforts are still at their genesis in Cameroon. It is however, worth noting that efforts geared toward the education of the girl child are yielding fruit, even if much remains to be done in rural areas. The only unfortunate revelation is that increase in the number of young girls in scientific classes observed in high school is not reflected at the tertiary level in physics. Thus, young women are almost completely absent when it comes to recruiting lecturers and researchers in the subject. It is time a serious study is carried out on the status of the woman physicist in Cameroon. It is time to evaluate the importance of the woman physicist to our society and to the field of study as well. It is also necessary to develop a new policy geared toward encouraging young girls to take up a career in physics.

    The Douala basin is predominantly an offshore basin extending from the Cameroon volcanic line in the north to the Corisco arch in the south near the Equatorial Guinea-Gabon border. The basin lies wholly within the territorial borders of Cameroon and Equatorial Guinea. The Douala basin is one of a series of divergent margin basins occurring along the southwest African coastline resulting from the rifting of Africa from South America. Continental rifting in the Doula basin was initiated at least by Aptian-Albian time and possibly as early as Jurassic. The rift stage persisted until Albian time when the onset of drifting occurred. The sedimentary section in the basin has a maximum thickness of 8-10 km, based on exploration drilling and gravity and magnetics modeling. The synrift section consists of Aptian-Albian sands and shales, deposited primarily as submarine fans, fan-deltas, and turbidite deposits. These are overlain by salt, thought to be equivalent to the Ezagna salt of Aptian age in the Gabon basin to the south. The synrift section is separated from the overlying postrift shale sequence of Late Cretaceous and Tertiary age by a major late Albian unconformity. The Douala basin has been explored for hydrocarbons intermittently over the last 25 years. Results show a distinct tendency for gas-proneness. The largest field recorded to date is the Sanaga Sud gas field, discovered in 1979, offshore, near the coastal city of Kribi.

    The Littoral region of Cameroon met most of its routine immunization and surveillance objectives in 2010 but has not reiterated such a performance since then. We describe the case-based measles surveillance performance of 2010 by person, place, time and determine measles surveillance system delays. Descriptive statistics were performed using Epi Info 3.5.3. There were 130 suspected measles cases investigated by 17 (89.5%) health districts, 83 (64%) males and 99 (76%) ≤5 years. At least 4 cases were investigated per month with a peak of 23 cases in June. About 67 (51.5%) patients visited a hospital more than 48 h after disease onset, 34 (26.2%) health facilities informed the district service late after receiving a suspected case and 65 (50%) samples got to the reference laboratory more than 24 hours after reception by the specimen collection centre. More than 2 discarded measles/100,000 population were investigated but with health facilities, specimen collection centre and patients’ ability to seek healthcare delays. All specimens got to the reference laboratory within 72 h. Patients’ health seeking behavior need to be improved and personnel involved in surveillance sensitized on timeliness. PMID:28299126

    Anemia is a common complication of chronic kidney disease. We investigated the prevalence, characteristics and management of anemia in patients on chronic hemodialysis and assessed the response to blood-transfusion based management in Cameroon. This was a cohort study of five months' duration (August-December 2008) conducted at the Yaoundé General Hospital's hemodialysis center, involving 95 patients (67 men, 70.5%) on chronic hemodialysis by a native arteriovenous fistula. A monthly evaluation included full blood counts, number of pints of red cell concentrates transfused, and vital status. At baseline, 75 (79%) patients had anemia which was microcytic and hypochromic in 32 (43%). Anemia was corrected in 67 (70.5%) patients using blood transfusion only, while 28 (29.5%) patients were receiving erythropoietin (11 regularly, 39%). Only 77.2% of 342 pints (median 3.0, range 0-17 per patients) of red cell concentrates prescribed were effectively received during the follow-up at an unacceptably high cost to patients and families. Mean hemoglobin and mean corpuscular hemoglobin levels remained stable during follow-up, while mean corpuscular volume increased. Erythropoietin treatment was the main determinant of favorable trajectories of hematological markers. Patients on chronic hemodialysis have predominantly microcytic hypochromic anemia, with limited capacity for correction using blood transfusion.

    Due to current spreading of chemoresistant strains of Plasmodium falciparum malaria control must incorporate vector control programmes. Due to well known constraints house sprayings cannot be performed as before. Personal protection can be developed and a large scale use of insecticide treated bed-nets appeared to be very useful to reduce man-vector contact in Asia, South America and West and East Africa. No trial has been done in forest Central Africa where transmission is permanent. We performed such a trial in the southern part of Cameroon (using deltamethrin, at 25 mg/m2) and obtained similar data to those observed in The Gambia, Burkina Faso and Tanzania with a noteworthy reduction of both transmission and high parasitaemia of P. falciparum (respectively 78% and 75%) meaning a drop of malaria morbidity.

    Effective triage is an important part of high quality emergency care, yet is frequently lacking in resource-limited settings. The South African Triage Scale (SATS) is designed for these settings and consists of a numeric score (triage early warning score, TEWS) and a list of clinical signs (known as discriminators). Our objective was to evaluate the implementation of SATS at a new teaching hospital in Haiti. A random sample of emergency department charts from October 2013 were retrospectively reviewed for the completeness and accuracy of the triage form, correct calculation of the triage score, and final patient disposition. Over and under triage were calculated. Comparisons were evaluated with chi-squared analysis. Of 390 charts were reviewed, 385 contained a triage form and were included in subsequent analysis. The final triage color was recorded for 68.4% of patients, clinical discriminators for 48.6%, and numeric score for 96.1%. The numeric score was calculated correctly 78.3% of the time; in 13.2% of patients a calculation error was made that would have changed triage priority. In 23% of cases, chart review identified clinical discriminators should have been circled but were not recorded. Overtriage and undertriage were 75.6% and 7.4% respectively. This study demonstrates that with limited structured training, SATS was widely adopted, but the clinical discriminators were used less commonly than the numeric score. This should be considered in future implementations of SATS. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Sepsis is one of the leading causes of neonatal morbidity and mortality. Because of difference in local epidemiology and possible variation with time, regular monitoring and updates on pathogen and their antimicrobial sensitivity pattern is important for prevention and treatment. A retrospective descriptive study was carried out among cases of neonatal sepsis admitted in neonatal intermediate care unit of Kanti Children's hospital from August 2014 to August 2015. The data was collected from medical records of neonatal intermediate care unit and microbiology department and analyzed using SPSS version 20. There were 644 admissions, among which 210 (32%)were suspected of having neonatal sepsis. Thirty(14%) of the suspected cases had positive blood culture. Proportions of late and early onset were 25 (83.3%) and 5(17.7%) respectively.In blood culture Staphylococcus aureus was the most common organism(80%),followed by Coagulase negative Staphylococcus (6.66%), Acinetobacter (6.66%), Enterobacter species(3.33%) and Morgonellamorgoni (3.33.5%).Gram positive organisms were isolated in all cases of early onset sepsis and in 84% of late onset sepsis. Most of the isolated organisms showed sensitivity to amikacin, cloxacillin, ciprofloxacin and vancomycin. This study has indicated possible emergence of Staphylococcus aureus as the dominant cause of neonatal sepsis. Cloxacillin, amikacin, ciprofloxacin have high proportion of efficacy against the commonly isolated bacteria in neonatal sepsis.

    Outbreaks of influenza epidemics are common but influenza vaccination is sub-optimal among the healthcare staff including the medical students. The study aims to assess the rate of vaccine uptake among medical students, its associated barriers and levels of awareness. A cross sectional study was done at a University Hospital in Saudi Arabia on 421 medical students by self administered questionnaire from February to March 2015. The immunization rate of seasonal influenza vaccine was just 20.7% in 2015, while it was 57% for cumulative of previous three-year period. The intended uptake among those offered vaccination was 68%. The significant determinants of vaccine uptake were clinical years of medical study (p<0.05) and previous history of vaccination (p<0.0001). The major sources influencing vaccine uptake decision were health department guidelines, medical training, social and media influence. Barriers of vaccination constituted, assumption of not being at risk of influenza (37.9%), vaccine side effects (28.9%), questioned effectiveness of the vaccine (14.5%), and inability to allocate time (11%). Knowledge levels were unsatisfactory and males scored lower (5.4±1.7) than females (6.5±1.4) out of total score of 9. Both knowledge and uptake of annual influenza vaccination was inadequate. Policy makers can formulate strategies with a focus on larger coverage of medical students. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Tuberculosis lymphadenitis is difficult to diagnose clinically, and often the laboratory confirmation is not available in resource-poor countries. We describe here the symptoms, clinical characteristics, and results of cytological analysis in peripheral tuberculous lymphadenitis patients. One hundred and fifty-six patients with peripheral lymph node for cytological evaluation presenting to Department of Pathology, Acharya Vinoba Bhave Rural Hospital, Wardha, India were included in this study. Sixty-nine cases were tuberculous lymphadenitis, with female to male ratio of 1.3:1. One or more constitutional symptoms were present in 59.4% of patients, with 89.9% of lymph nodes ≥2×2cm and the most common site of involvement was cervical lymph node (70.3%). The lymph nodes were multiple (85.5%), either discrete or matted. Cytomorphologically, hemorrhagic aspirate was observed in 29 cases, well-formed epithelioid cell granuloma with caseous necrosis was seen in 34 cases, and Zeihl Neelsen staining was positive in 45 cases. Correlation between character of aspirate and cytomorphological pattern was found highly significant. These data suggest that constitutional symptoms and clinical and cytological features help in diagnosing cases of peripheral tubercular lymphadenitis and also open new frontiers to further research that affects the cytological features of these cases.

    (1) Background: An analysis of work-related accidents in paramedics in Poland by presenting the model and trend of accidents, accident rates and by identifying causes and results of accidents; (2) Methods: A retrospective analysis of medical documentation regarding work-related accidents in a multi-specialist hospital, located in central Poland, in the period 2005–2015. The study group included paramedics who had an accident while being on duty; (3) Results: According to hospital records, 88 paramedics were involved in 390 accidents and 265 injuries caused by sharp instruments. The annual accident rate was 5.34/100 employed paramedics. Most of the accidents occurred at night. The most common reason for the accident was careless behaviour of the paramedic, which resulted in joint sprains and dislocations. Injuries accounted for a huge portion of the total number of events. As many as 45% of injuries were not officially recorded; (4) Conclusion: High rates of work-related accidents and injuries caused by sharp instruments in paramedics are a serious public health problem. Further studies should be conducted in order to identify risk factors of accidents, particularly injuries, and to implement preventative programmes, aiming to minimise rates of occupational hazards for paramedics.

    Purpose: To evaluate the level of knowledge, attitudes, and barriers to diabetic retinopathy (DR) screening among diabetic healthcare staff at a tertiary eye hospital in central Saudi Arabia. Methods: This was a descriptive survey using a closed-ended questionnaire. A. 5-grade. Likert scale was used for responses to each question. Data were collected on patient demographics and the status of diabetes. Survey responses related to knowledge, attitude, and barriers were grouped. Results: The study sample was comprised of 45 diabetics employed at the hospital. The mean age was 49 ± 11 years and 33 diabetics were males. One-third of the study population was referred to the eye clinic for DR screening. DR screening was performed in 25% of diabetics over the previous year. Twenty-nine (64%; 95% confidence intervals: 50–78) participants had excellent knowledge of eyecare for diabetic complications. Thirteen percent of participants had a positive attitude toward periodic eye checkups. Travel distance to an eyecare unit, no referral from family physicians for annual eye checkups and the lack of availability of gender-specific eyecare professionals were the main perceived barriers. Conclusion: Annual DR screening needs to be promoted to primary healthcare providers and diabetic patients. Barriers should be addressed to improve the uptake of DR screening. PMID:26957842

  11. Seismic reflection character of the Cameroon volcanic line: Evidence for uplifted oceanic crust

    Deep-imaging multifold seismic lines across submarine parts of the Cameroon volcanic line (west Africa-Gulf of Guinea) show asymmetric uplift of oceanic crust associated with extensive magmatism. The main pulse of uplift occurred after creation of a regional sequence boundary believed to be Miocene in age. The apparent synchroneity of uplift argues against the Cameroon line being a simple hotspot trace, as previously inferred. One plausible theory of origin for the seaward part of the Cameroon volcanic line and its asymmetric uplift geometry combines regional asthenospheric upwelling with restriction of magmatic egress to regularly spaced weak spots, corresponding to fracture-zone crossings. Horizontal motion and buckling also may have occurred along the Cameroon volcanic line.

    We present the mineralogy and age of the magmatic epidote-bearing granite composing most of the Mokong pluton, in the Central Africa orogenic belt (North Cameroon). This pluton intrudes Neoproterozoic (~830 to 700 Ma) low- to high-grade schists and gneisses (Poli-Maroua group), and is crosscut or interleaved with bodies of biotite granite of various sizes. The pluton is weakly deformed in its interior, but solid-state deformation increases toward its margins marked by narrow mylonitic bands trending NNE-SSW. The magmatic epidote granitic rocks are classified as quartz monzodiorite, granodiorite, monzogranite, and syenogranite. They are medium- to coarse-grained and composed of K-feldspar + plagioclase + biotite + amphibole + epidote + magnetite + titanite + zircon + apatite. In these granites, the pistacite component [atomic Fe+3/(Fe3+ + Al)] in epidote ranges from 16 to 29 %. High oxygen fugacity (log ƒO2 - 14 to -11) and the preservation of epidote suggest that the magma was oxidized. Al-in hornblende barometry and hornblende-plagioclase thermometry indicate hornblende crystallization between 0.53 and 0.78 GPa at a temperature ranging from 633 to 779 °C. Zircon saturation thermometry gives temperature estimates ranging from 504 to 916 °C, the latter being obtained on samples containing inherited zircons. U/Pb geochronology by LA-ICP-MS on zircon grains characterized by magmatic zoning yields a concordia age of 668 ± 11 Ma (2 σ). The Mokong granite is the only known occurrence magmatic epidote in Cameroon, and is an important milestone for the comparison of the Central Africa orogenic belt with the Brasiliano Fold Belt, where such granites are much more abundant.

    The Cameroon Volcanic Line (CVL) is a 1800km long feature, extending SW-NE from the Gulf of Guinea into Central Africa. Volcanism along the line does not display the typical age progression exhibited by hotspot-related volcanic tracks, leading to speculation over the geodynamic source of this intraplate feature. Numerous models have been proposed to explain the linear nature of the CVL in the absence of age progression, including laterally transported material from a single or multiple plumes, reactivation of the Central African Shear Zone, edge-flow convection associated with the neighboring Congo Craton, and convection driven by lithospheric instabilities at the edge of continental lithosphere. In this study, we calculate Rayleigh wave phase velocities and upper mantle shear wave velocity structure beneath the continental portion of the CVL to investigate the geodynamic source of the CVL. Rayleigh wave phase velocities are measured at periods from 20 to 182 seconds following the two-plane wave methodology developed by Forsyth and Li (2005), and using data from the Cameroon Seismic Experiment, which consists of 32 broadband stations deployed between 2005 and 2007. These phase velocities are then inverted to build a model of shear wave velocity structure in the upper mantle beneath the CVL. We find that phase velocities beneath the CVL are reduced, while velocities beneath the Congo Craton to the south are elevated. This is observed for all periods, but the difference between regions decreases at the longest periods measured in the study. Shear wave velocity structure indicates a tabular low velocity anomaly directly beneath the CVL, extending from 50km to at least 200km depth, with a sharp vertical boundary with the faster velocities beneath the Congo Craton. These observations are most consistent with the edge convection or lithospheric instability models as the source of the continental CVL. Further study of offshore structure will aid in better characterizing

    During October 2013-June 2014, approximately 54,000 unaccompanied children, mostly from the Central American countries of El Salvador, Guatemala, and Honduras, were identified attempting entry into the United States from Mexico, exceeding numbers reported in previous years. Once identified in the United States, U.S. Customs and Border Protection, an agency of the U.S. Department of Homeland Security, processes the unaccompanied children and transfers them to the Office of Refugee Resettlement (ORR), an office of the Administration for Children and Families, U.S. Department of Health and Human Services. ORR cares for the children in shelters until they can be released to a sponsor, typically a parent or relative, who can care for the child while their immigration case is processed. In June 2014, in response to the increased number of unaccompanied children, U.S. Customs and Border Protection expanded operations to accommodate children at a processing center in Nogales, Arizona. ORR, together with the U.S. Department of Defense, opened additional large temporary shelters for the children at Lackland Air Force Base, Texas; U.S. Army Garrison Ft. Sill, Oklahoma; and Naval Base Ventura County, California.

    Objectives Reduced biocide susceptibility in Staphylococci is associated with various antiseptic resistance genes encoding efflux systems. Our aim was to determine the susceptibility to three disinfectant agents, including benzalkonium chloride (BAC), benzethonium chloride (BZT), and chlorhexidine digluconate (CHDG) among clinical isolates of Staphylococcus aureus and coagulase-negative Staphylococci (CoNS). Methods The minimum inhibitory concentration (MIC) of 60 methicillin-resistant S. aureus (MRSA), 54 methicillin-sensitive S. aureus (MSSA) and 51 CoNS isolates from a single hospital to three biocidal agents (BAC, BZT, and CHDG) was determined. Biocide resistance genes (qacA/B, smr, qacG, qacH, qacJ, and norA) were analyzed by the polymerase chain reaction assay. Results All isolates had MICs for BAC and BZT from 0.25 to 8 µg/mL, and for CHDG from 0.5 to 64 µg/mL. qacA/B was the most common biocide resistance gene among all 165 Staphylococcus isolates (76; 46%), which comprised 38 (63.3%) MRSA, 14 (25.9%) MSSA, and 24 (47%) CoNS. Eleven (6.7%) and 24 (14.5%) isolates among the 165 Staphylococci carried smr and norA genes, respectively. In contrast, other resistance genes such as qacG, qacH, and qacJ were absent in all Staphylococci studied. The qacA/B and smr genes were detected concomitantly in 3% of isolates, and 23.6% strains of the total 165 Staphylococcus isolates were negative for each studied gene. Conclusions The carriage of several biocide resistance genes, including qacA/B, smr, and norA, alone or concurrently, is associated with reduced susceptibility. Use of antiseptics may select for antibiotic-resistant strains and assist their survival in the healthcare environment. PMID:27974958

    The purpose of this study was to define the demographics of pediatric traumatic injuries and to understand the predictive value of injury type, prehospital, and emergency department (ED) data regarding the mortality of pediatric trauma patients (<14 years of age) in South Central Texas. We report a retrospective review of pediatric trauma patients presenting to Trauma Service Area P in South Central Texas during 2004-2013. The primary outcome was mortality; secondary outcomes were ventilator days, hospital days, and intensive care unit stay. Demographics, Abbreviated Injury Score (AIS) codes, ICD-9 codes, transport times, Emergency Medical Services (EMS) vital signs en route and on arrival to the emergency department (ED), and outcomes were evaluated. A total of 8004 traumatically injured children presented to EDs in South Central Texas during the study period; 4109 of these presented via EMS. Most patients were Hispanic and male. Distribution was even across age groups. Overall mortality was 2%, and the mortality of those arriving by EMS was 3.7%. Abnormal vital signs and Glasgow Coma Score upon presentation to both EMS and the ED were strongly associated with mortality. Increased Injury Severity Score, the need for transfusion in the ED, and increased maximal AIS were also strongly associated with mortality. African American race was associated with increased mortality, although transport time and age were not. Most injuries overall were caused by motor vehicle collisions; however, burns and falls were most common in infants. The most lethal injuries were caused by firearms (mostly seen in preteens) and assaults (mostly seen in infants). This analysis of injured children in Southwest Texas offers insight into areas of needed quality improvement in the trauma system and potential areas to focus prevention efforts.

    Suitability of environmental conditions determines a species distribution in space and time. Understanding and modelling the ecological niche of mosquito disease vectors can, therefore, be a powerful predictor of the risk of exposure to the pathogens they transmit. In Africa, five anophelines are responsible for over 95% of total malaria transmission. However, detailed knowledge of the geographic distribution and ecological requirements of these species is to date still inadequate. Indoor-resting mosquitoes were sampled from 386 villages covering the full range of ecological settings available in Cameroon, Central Africa. Using a predictive species distribution modeling approach based only on presence records, habitat suitability maps were constructed for the five major malaria vectors Anopheles gambiae, Anopheles funestus, Anopheles arabiensis, Anopheles nili and Anopheles moucheti. The influence of 17 climatic, topographic, and land use variables on mosquito geographic distribution was assessed by multivariate regression and ordination techniques. Twenty-four anopheline species were collected, of which 17 are known to transmit malaria in Africa. Ecological Niche Factor Analysis, Habitat Suitability modeling and Canonical Correspondence Analysis revealed marked differences among the five major malaria vector species, both in terms of ecological requirements and niche breadth. Eco-geographical variables (EGVs) related to human activity had the highest impact on habitat suitability for the five major malaria vectors, with areas of low population density being of marginal or unsuitable habitat quality. Sunlight exposure, rainfall, evapo-transpiration, relative humidity, and wind speed were among the most discriminative EGVs separating "forest" from "savanna" species. The distribution of major malaria vectors in Cameroon is strongly affected by the impact of humans on the environment, with variables related to proximity to human settings being among the best

    Background Speciation among members of the Anopheles gambiae complex is thought to be promoted by disruptive selection and ecological divergence acting on sets of adaptation genes protected from recombination by polymorphic paracentric chromosomal inversions. However, shared chromosomal polymorphisms between the M and S molecular forms of An. gambiae and insufficient information about their relationship with ecological divergence challenge this view. We used Geographic Information Systems, Ecological Niche Factor Analysis, and Bayesian multilocus genetic clustering to explore the nature and extent of ecological and chromosomal differentiation of M and S across all the biogeographic domains of Cameroon in Central Africa, in order to understand the role of chromosomal arrangements in ecological specialisation within and among molecular forms. Results Species distribution modelling with presence-only data revealed differences in the ecological niche of both molecular forms and the sibling species, An. arabiensis. The fundamental environmental envelope of the two molecular forms, however, overlapped to a large extent in the rainforest, where they occurred in sympatry. The S form had the greatest niche breadth of all three taxa, whereas An. arabiensis and the M form had the smallest niche overlap. Correspondence analysis of M and S karyotypes confirmed that molecular forms shared similar combinations of chromosomal inversion arrangements in response to the eco-climatic gradient defining the main biogeographic domains occurring across Cameroon. Savanna karyotypes of M and S, however, segregated along the smaller-scale environmental gradient defined by the second ordination axis. Population structure analysis identified three chromosomal clusters, each containing a mixture of M and S specimens. In both M and S, alternative karyotypes were segregating in contrasted environments, in agreement with a strong ecological adaptive value of chromosomal inversions. Conclusion Our

  19. Sustaining mother tongue medium education: An inter-community self-help framework in Cameroon

    Advocating mother tongue education implies recognising the centrality of linguistic and cultural diversity in quality and accessible education planning and delivery. In minority linguistic settings, this need becomes particularly urgent. Decades of exclusive promotion of foreign languages have rendered the educational system incapable of guaranteeing maximum quality, accessibility and equity. Also, due to long periods of marginalisation and disempowerment, most indigenous communities are unable to undertake viable self-reliant educational initiatives. As a result, planning and management of education is not adapted to the needs and realities of target populations. What such an educational approach has succeeded in achieving is to cultivate a culture of near-total dependence and consumerism. In minority language situations where mother tongue education is still primarily in the hands of private institutions and individuals, successful planning also means influencing the perceptions and attitudes of indigenous people and systematically integrating them into the educational process. This paper discusses grass-roots mother tongue education in Cameroon. It focuses on the inter-community self-help initiative as a local response framework and argues that this initiative is a strong indication of the desire of communities to learn and promote learning in their own languages.

    One possible explanation of the maintenance of many historical foci of sleeping sickness in Central Africa could be the existence of a wild animal reservoir. In this study, PCR was used to detect the different trypanosome species present in wild animal captured by hunters in the southern forest belt of Cameroon (Bipindi). Trypanosomes were also detected by a parasitological method (Quantitative buffy coat: QBC). Parasite could not be isolated in culture medium (Kit for in vitro isolation: KIVI). Specific primers of T. brucei s.l., T. congolense forest type, T. congolense savannah type, T. vivax, T. simiae and T. b. gambiense group 1 were used to identify parasites in the blood of 164 animals belonging to 24 different species including ungulates, rodents, pangolins, carnivores, reptiles and primates. Of the 24 studied species, eight were carrying T. b. gambiense group 1. Those parasites pathogenic to man were found in monkeys (Cercocebus torquatus and Cercopithecus nictitans), in ungulates (Cephalophus dorsalis and C. monticola), in carnivores (Nandinia binotata and Genetta servalina) and in rodents (Cricetomys gambianus and Atherurus africanus). 13 species (54%) were carrying T. brucei s.l. identified as non-gambiense group 1.

    Fifty-eight fusaria isolated from 50 Italian patients between 2004 and 2007 were subject to multilocus DNA sequence typing to characterize the spectrum of species and circulating sequence types (STs) associated with dermatological infections, especially onychomycoses and paronychia, and other fusarioses in northern and central Italy. Sequence typing revealed that the isolates were nearly evenly divided among the Fusarium solani species complex (FSSC; n = 18), the F. oxysporum species complex (FOSC; n = 20), and the Gibberella (Fusarium) fujikuroi species complex (GFSC; n = 20). The three-locus typing scheme used for members of the FSSC identified 18 novel STs distributed among six phylogenetically distinct species, yielding an index of discrimination of 1.0. Phylogenetic analysis of the FOSC two-locus data set identified nine STs, including four which were novel, and nine isolates of ST 33, the previously described widespread clonal lineage. With the inclusion of eight epidemiologically unrelated ST 33 isolates, the FOSC typing scheme scored a discrimination index of 0.787. The two-locus GFSC typing scheme, which was primarily designed to identify species, received the lowest discrimination index, with a score of 0.492. The GFSC scheme, however, was used to successfully identify 17 isolates as F. verticillioides, 2 as F. sacchari, and 1 as F. guttiforme. This is the first report that F. guttiforme causes a human mycotic infection, which was supported by detailed morphological analysis. In addition, the results of a pathogenicity experiment revealed that the human isolate of F. guttiforme was able to induce fusariosis of pineapple, heretofore its only known host. PMID:20107100

    We illustrate the use of Faith's 'Phylogenetic Diversity' measure to compare the phylogeographic structure of two bird species with patterns of avian endemism across six mountains in Cameroon and Equatorial Guinea. The Mountain Greenbul and Cameroon Blue-headed Sunbird showed phylogeographic patterns that together defined three biogeographic regions: Bioko, Mt. Cameroon, and the northern mountains of Cameroon. In contrast, the distributions of endemic species were largely a function of geographical distance, with close mountains sharing more endemic species than distant mountains. Moreover, for both species, populations on Mt. Cameroon were distinctive with respect to the ecologically relevant character bill size. Our results, while preliminary, illustrate the utility of a comparative approach for identifying geographical regions that harbour evolutionarily distinct populations and caution against using only the distributional patterns of endemics to prioritize regions for conservation. Results show that patterns of endemism may not be concordant with patterns of phylogenetic diversity nor morphological variation in a character important in fitness. While incorporation of additional species from unrelated taxa will be necessary to draw definitive conclusions about evolutionarily distinct regions, our preliminary results suggest a conservation approach for the Afromontane region of the Gulf of Guinea that would: (i) emphasize protection of both Bioko and Mt. Cameroon, thereby maximizing preservation of within-species phylogenetic and morphologic diversity; (ii) emphasize protection within the northern mountains to further conserve intraspecific phylogenetic diversity and maximize protection of endemic species.

    Native of rural West Cameroon, the Bamiléké population is traditionally predisposed to obesity. Bamiléké who migrated to urban areas additionally experience the nutrition transition. We investigated the biocultural determinants of obesity in Bamiléké who migrated to urban Cameroon (Yaoundé), or urban France (Paris). We conducted qualitative interviews (n = 36; 18 men) and a quantitative survey (n = 627; 266 men) of adults using two-stage sampling strategy, to determine the association of dietary intake, physical activity and body weight norms with obesity of Bamiléké populations in these three socio-ecological areas (rural Cameroon: n = 258; urban Cameroon: n = 319; urban France: n = 50). The Bamiléké valued overweight and traditional energy-dense diets in rural and urban Cameroon. Physical activity levels were lower, consumption of processed energy-dense food was frequent and obesity levels higher in new migrants living in urban Cameroon and France. Female sex, age, duration of residence in urban areas, lower physical activity and valorisation of overweight were independently associated with obesity status. This work argues in favour of local and global health policies that account for the origin and the migration trajectories to prevent obesity in migrants. PMID:28661463

  4. Gas bursts from cameroon crater lakes: a new natural hazard.

    Gas bursts from tropical crater lakes constitute a hitherto unrecognized natural hazard, which claimed 37 lives around Lake Monoun in 1984 and 1,746 lives in 1986 around Lake Nyos in Cameroon, west Africa. Studies of these events indicate that the lethal gas clouds were dominantly CO(2) which exsolved catastrophically from deep waters of the lakes, producing in the case of Lake Nyos a gas cloud of 1.94 times 10(6) tons CO(2) . Carbon-isotope data indicate a magmatic source of the carbon dioxide, but the geochemistry of deep water and gases does not support a sudden injection of volcanic gas from a deep source into the lakes. Rather, it is proposed that the gas bursts were preceded by gradual build-up of dissolved bicarbonate in deep waters, where anoxic conditions in enclosed and stagnant basins led to low pH and pCO(2) close to saturation. Steady input from the Earth's mantle to submerged mofettes or CO(2) -rich soda springs within the lakes is most likely the primary source of carbon dioxide. Lethal effects of the gas bursts are almost entirely due to CO(2) -induced asphyxia. A small percentage of victims awoke from coma one or two days after the event, but most died. Unusual skin lesions on about 5% of victims arose from the comatose state. It is shown that the mass of gas required to account for the lethal effects and observed gas clouds is an order of magnitude less than the potential gas yield from the lakes. In view of the lethal gas bursts from the small Cameroon lakes, the potential hazard of future gas bursts from other much larger density-stratified equatorial lakes must be seriously considered, particularly in Lake Kivu in east Africa, where methane and carbon dioxide gas content is higher by two to four orders of magnitude than that of the Cameroon lakes. A gas burst from Lake Kivu would form a carbon dioxide cloud up to 340 km(3) in volume and expansion of the exsolving gas from deep water to atmospheric pressure would correspond to an energy release

    To assess the pattern of dentofacial injuries in commercial motorcycle accidents among riders and passengers in Cameroon. This was a hospital based study conducted in 6 out of 10 regional capitals in the months of December 2011 to September 2012. Analyzed information included age, gender, residence, role on the motorcycle (rider or passenger), type, pattern and month of injury, cost, duration and patient's perception about the cost of treatment. A total of 387 patients were studied with majority of the patients being 21-30 years (39.8%), males (63.8%), passengers (57.3%) and urban dwellers (85.8%). Most of the injuries occurred in December (20.7%), January (19.4%) and February (20.2%). Soft tissue injuries were most frequent (91.2%) followed by trauma to the teeth (83.5%), of which 62.3% were tooth loss. Mandibular fracture was commoner than maxillary fracture; (45% versus 25.3%). A total of 44.2% of patients received their treatment as in-patients. The treatment of the dentofacial injuries among 64.3% of the patients lasted for more than a month. A total of 51.9% of the patients spent 100,000 francs ($200) or more for their treatment. More than half (51.4%) of the patients perceived the cost of treatment as expensive. Dentofacial injuries in commercial motorcycle accidents necessitated hospital admission and lengthy treatment time with high attendant cost. Preventing these injuries will serves as a form of poverty reduction as money that will be used by the victim to better their life is not used to correct deformities or treat injuries.

    Malnutrition is the fourth commonest reason for hospital admission to the paediatric department of the Central Hospital, Maputo and has the second highest death rate (20 per cent). A study from 1995 into mortality at this paediatric department, suggested an increase in severe malnutrition. Recent studies have shown that the global burden of undernutrition in the world is declining; however, data for Eastern Africa shows a deterioration. The current study was aimed at describing and comparing the patients on the malnutrition ward, in 2001 and 1983. The study gathered indices of nutritional status and secondary diagnoses from the notes of all children (aged between 6 months and 5 years) discharged from the malnutrition ward for a period of l year (January-December 2001), and from data (collected in January-December 1983) for the malnutrition ward. Data was entered and analysed using Epi-Info 6 and SPSS statistics package. The ethics committee of the hospital approved the study. Data was collected for 558 children in 2001 and 833 in 1983. There was no gender difference, average age was 21.7 months in 2001 and 23.8 months in 1983 and the average hospital stay was 13.1 and 14.3 days, respectively. In 2001, 33 per cent had kwashiorkor, 26 per cent marasmus, and 28 per cent marasmic kwashiorkor. Three hundred and twenty children (82 per cent) were <2 Z-scores below the median weight-for-age and 252 children (65 per cent) were <3 Z-scores. Forty per cent had malaria, 65 per cent anaemia, 53 per cent bronchopneumonia, 14 per cent TB, 36 per cent diarrhoea, and 12 per cent HIV/AIDS. In 1983, 49 per cent had kwashiorkor, 17 per cent marasmus, and 11 per cent had marasmic kwashiorkor. A total of 494 children (81 per cent) were <2 Z-scores below the median weight-for-age and 335 children (55 per cent) were <3 Z-scores. Eighteen per cent had malaria, 37 per cent anaemia, 28 per cent bronchopneumonia, 6 per cent TB, 8 per cent diarrhoea, and 4.4 per cent measles/post-measles. A

    Background Hypertension is associated with considerable morbidity and mortality. Improvement of its management to reduce adverse cardiovascular outcomes will require an understanding of the patient characteristics and treatment factors associated with uncontrolled blood pressure. Factors that affect blood pressure control have not been sufficiently described in Cameroon. The main goal of our study was to determine the predictors of blood pressure control in patients with hypertension in an urban city in Cameroon. Methods This was descriptive cross-sectional study from five outpatient hypertension consultation units in Hospitals in Yaoundé. Controlled hypertension was defined as blood pressure ≤140/90 mmHg. Logistic regression was used to determine factors associated with blood pressure control. Results Among the 440 patients enrolled in the survey, 280 (63.6%) were females. The mean age was 61 (SD ±11) years. Mean systolic blood pressure (SBP) was 147 mmHg and mean diastolic blood pressure (DBP) was 88 mmHg. Only 36.8% of patients had their mean blood pressure controlled (BP ≤140/90 mmHg). Multivariable logistic regression analysis revealed good adherence to anti-hypertensive medications (OR= 3.99; 95% CI: 2.20–7.23; P<0.000) and dietary lifestyle changes (OR =1.5; 95% CI: 0.53–2.49; P=0.031) to be factors independently associated with controlled hypertension. Conclusions Only one out of three patients has their blood pressure controlled. The results of our study suggest that good adherence to treatment are important factors for tight blood pressure control in primary care. Further identification of patients at risk of non-adherence to treatment and poor blood pressure control can lead to targeted interventions to reduce hypertension related morbidity and mortality in this setting.

    Sensitisation of asthmatic patients to mites in sub-Saharan Africa has been less described. The aim of this study was to assess the prevalence and determinants of sensitisation to mites in asthmatic adolescents and adults in Yaounde, Cameroon. This was a cross-sectional study. Logistic regression models were employed to investigate the determinants of sensitisation to mites. This study was carried out at the Jamot Hospital and CEDIMER private centre, in Yaounde, capital city of Cameroon. All asthmatic patients received in consultations from January 2012 to June 2013 and in whom prick-skin tests for perennial aeroallergens were performed were included. Prevalence of sensitisation to mites and associated factors. In total, 201 patients (132 being women, 65.7%), with a median age of 36 (25th-75th centiles: 20-54) years were included, with 135 (67.2%) having a positive skin test for mites. Sensitisation to Dermatophagoïdes pteronyssinus, Dermatophagoides farinae and Blomia tropicalis was found in 53.2%, 49.8% and 47.8% of the patients, respectively. Intermittent rhinitis (16.3% vs 7.6%) and persistent rhinitis (43.0% vs 22.7%) were more frequent in sensitised patients than in the non-sensitised ones (p<0.010). Independent allergological determinants of sensitisation to mites were sensitisation to Alternaria alternata (adjusted OR 14.98 (95% CIs 1.96 to 114.4)) and sensitisation to Blattella germanica (3.48 (1.34 to 9.00)). Sensitisation to mites was found in about two-thirds of asthmatic patients in this setting, with a frequent multiple sensitisations to A alternata and Blattella germanica. Systematically investigating asthmatic patients for mites' sensitisation and determinants will help optimising the care in this setting by combining the aetiological treatment for the allergy with symptomatic treatment for asthma, in order to modify the natural course of the disease.

    The sudden, catastrophic release of gas from Lake Nyos on 21 August 1986 caused the deaths of at least 1700 people in the northwest area of Cameroon, West Africa. Chemical, isotopic, geologic, and medical evidence support the hypotheses that (i) the bulk of gas released was carbon dioxide that had been stored in the lake's hypolimnion, (ii) the victims exposed to the gas cloud died of carbon dioxide asphyxiation, (iii) the carbon dioxide was derived from magmatic sources, and (iv) there was no significant, direct volcanic activity involved. The limnological nature of the gas release suggests that hazardous lakes may be identified and monitored and that the danger of future incidents can be reduced.

    A unique humanitarian, scientific, and technical experiment is currently taking place in a forgotten mountainous region of West Africa. The experiment is on the verge of reaching its operational stage, which consists of the eradication of a ``new'' natural hazard; one that is potentially devastating, but which has been known for only 20 years. The Lake Nyos catastrophe, which claimed 1800 victims in August 1986, was not unprecedented. Indeed, two years previously, a lethal gas burst, originating from nearby Lake Monoun in the same remote area of Cameroon, killed 37 people-an odd and tragic episode that went almost unnoticed. One had never before heard of Mother Nature asphyxiating human beings and most higher animals on such a scale in a single and brief non-volcanic event.

    The author discusses the pro-natalist policies of Cameroon, measures that are not explicit population policies but are instead implied in other government policies and pronouncements. It is argued that "this pronatalist policy partly has its roots in the inherent cultures of the people which have been forged from several years of ravages from epidemic and endemic diseases, inter-tribal conflicts and slave trade. These have been further authenticated, constitutionalised and perpetuated by official policy which bears the stamp of its French colonial masters...." These policies include "legislation against contraception and abortions, discriminatory taxation in favour of married persons, family allowances and other travel, leave, transfer, retirement, housing and educational benefits and concessions for persons with large families as well as an elaborate network of mother and child health care centers." Attention is also given to the establishment of family planning and family care clinics, contraceptive availability, and illegal abortions. (SUMMARY IN FRE)

    A serological survey for human T cell leukaemia virus (HTLV)/simian T cell leukaemia virus (STLV) antibodies was performed in 61 wild-caught African apes, including five gorillas and 56 chimpanzees originating from south Cameroon. Two young animals, a gorilla (Gorilla gorilla gorilla) and a chimpanzee (Pan troglodytes vellerosus), exhibited a pattern of complete HTLV-I seroreactivity. Sequence comparison and phylogenetic analyses using the complete LTR (750 bp) and a 522 bp fragment of the env gene indicated the existence of two novel STLV-I strains, both of which belonged to HTLV-I/STLV-I molecular clade subtype B, specific to central Africa. These first STLV-I strains to be characterized in gorilla and chimpanzee were closely related to each other as well as to several HTLV-I strains originating from inhabitants of south Cameroon, including pygmies. Such findings reinforce the hypothesis of interspecies transmission of STLV-I to humans, leading to the present day distribution of HTLV-I in central African inhabitants.

    Background While wild chimpanzees are experiencing drastic population declines, their numbers at African rescue and rehabilitation projects are growing rapidly. Chimpanzees follow complex routes to these refuges; and their geographic origins are often unclear. Identifying areas where hunting occurs can help law enforcement authorities focus scarce resources for wildlife protection planning. Efficiently focusing these resources is particularly important in Cameroon because this country is a key transportation waypoint for international wildlife crime syndicates. Furthermore, Cameroon is home to two chimpanzee subspecies, which makes ascertaining the origins of these chimpanzees important for reintroduction planning and for scientific investigations involving these chimpanzees. Results We estimated geographic origins of 46 chimpanzees from the Limbe Wildlife Centre (LWC) in Cameroon.

    While wild chimpanzees are experiencing drastic population declines, their numbers at African rescue and rehabilitation projects are growing rapidly. Chimpanzees follow complex routes to these refuges; and their geographic origins are often unclear. Identifying areas where hunting occurs can help law enforcement authorities focus scarce resources for wildlife protection planning. Efficiently focusing these resources is particularly important in Cameroon because this country is a key transportation waypoint for international wildlife crime syndicates. Furthermore, Cameroon is home to two chimpanzee subspecies, which makes ascertaining the origins of these chimpanzees important for reintroduction planning and for scientific investigations involving these chimpanzees. We estimated geographic origins of 46 chimpanzees from the Limbe Wildlife Centre (LWC) in Cameroon. Using Bayesian approximation methods, we determined their origins using mtDNA sequences and microsatellite (STRP) genotypes compared to a spatial map of georeferenced chimpanzee samples from 10 locations spanning Cameroon and Nigeria. The LWC chimpanzees come from multiple regions of Cameroon or forested areas straddling the Cameroon-Nigeria border.

    An innovative, low-cost bubble continuous positive airway pressure (bCPAP) device has recently been introduced in Malawi for the treatment of respiratory distress in infants. While this novel bCPAP system has been shown to be safe and effective in reducing infant mortality, caregivers' experiences have not been investigated. The purpose of this study was to explore experiences of parents and guardians of infants who had been on bCPAP at Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi. This was a descriptive phenomenological study that was carried out at the Chatinkha nursery unit and the paediatric nursery ward at QECH, from January to February 2015. Purposive sampling was used to select participants for in-depth interviews. Data saturation was reached with 12 caregivers. Data were analysed using Colaizzi's framework. Caregivers received inadequate, inconsistent, and sporadic information about bCPAP. Student nurses and doctors were best able to answer caregivers' questions and concerns. When their infants were on bCPAP, caregivers felt anxious and fearful. However, upon implementation of bCPAP treatment for their children, the caregivers were satisfied with it. The main sources of psychological stress were limited parent-child interaction and the constraints of prescribed visiting hours. Family, friends, and caregiver involvement in the care of infants provided some psychological comfort. The results show gaps in the information and psychological support that mothers of infants on bCPAP receive in hospital. We recommend that psychological support be given to the mothers of infants on bCPAP at QECH.

    The aim of the study was to describe the clinical and epidemiological characteristics of the central nervous system (CNS) infection by varicella zoster virus (VZV) in patients older than 65 years in a tertiary community hospital. We retrospectively analysed the results of cerebrospinal fluid (CSF) testing in patients older than 65 years between 2007 and 2014 with clinically suspected VZV infection with CNS involvement. Patients whose CSF samples were positive for VZV DNA were included, as were those with negative results who simultaneously presented herpes zoster and CSF or magnetic resonance imaging findings suggestive of CNS infection, and in whom other possible aetiologies had been ruled out. The study included 280 patients. The disease was considered to be caused by a VZV infection in 32 patients (11.4%), of which 23 cases were virologically confirmed (detection of VZV DNA in CSF). The most frequent diagnosis of the patients with VZV CNS infection was encephalitis (83.3%), followed by meningitis (13.3%) and cerebellitis (3.3%). The mean annual incidence of VZV CNS infection was 3.0 cases per 100,000 inhabitants. VZV was the most common cause of encephalitis and viral meningitis, ahead of herpes simplex virus (n = 9). At the time of discharge, 12 (40%) patients showed neurological sequelae. Five patients (20%) died during hospitalization, all with encephalitis. Patients with a fatal outcome had significantly higher median age and longer delay before initiating acyclovir. In conclusion, VZV was the first cause of encephalitis in our elderly population. Despite acyclovir treatment, there was a high rate of case fatality and sequelae at discharge.

    Afrormosia laxiflora (A. laxiflora), Chenopodium ambrosioides (C. ambrosioides), Microglossa pyrifolia (M. pyrifolia) and Mimosa pudica (M. pudica) are plants used in traditional medicine in Cameroon to treat insomnia, epilepsy, anxiety, and agitation. They were evaluated for their anxiolytic like activity in mice. Animal models (elevated plus maze and stress-induced hyperthermia tests) were used. The four plants showed anxiolytic activity. In stress-induced hyperthermia test, A. laxiflora, C. ambrosioides, M. pyrifolia and M. pudica significantly antagonised the increase of temperature. ΔT° decreased from 0.75°C in the control group to 0.36°C at the dose of 110 mg/kg for A. laxiflora; from 1°C in the control group to -1.1°C at the dose of 120 mg/kg for C. ambrosioides; from 1.7°C in the control group to 0.2°C at the dose of 128 mg/kg for M. pyrifolia and from 1.3°C in the control group to 0.5°C at the dose of 180 mg/kg for M. pudica. In the elevated plus maze test, the four plants increased the number of entries into, percentage of entries into, and percentage of time in open arms. A. laxiflora, C. ambrosioides and M. pudica also reduced the percentage of entries and time in closed arms. In addition, C. ambrosioides, M. pyrifolia and M. pudica showed antipyretic activity by reducing the body temperature. The results suggested that C. ambrosioides, M. pyrifolia and M. pudica posses anxiolytic-like and antipyretic activities while A. laxiflora possesses only anxiolytic-like properties. These plants could be helpful in the treatment of anxiety and fever in traditional medicine in Cameroon.

    To increase the understanding of crustal deformation and crustal flow patterns due to tectonic processes in Cameroon, we study the lateral variability of the crustal isotropic velocity and radial anisotropy estimated using Ambient Noise Tomography (ANT). Rayleigh and Love wave Noise Correlation Functions (NCFs) were retrieved from the cross-correlation of seismic ambient noise data recorded in Cameroon, and phase velocities at periods of 8 to 30 s were measured to perform surface wave tomography. Joint inversion of Rayleigh and Love wave data for isotropic velocity models could not fit the observed dispersions simultaneously. We attribute the Love-Rayleigh discrepancy to the presence of radial anisotropy in the crust and estimated its magnitude. Our 3-D radial anisotropic model reveals the spatial variation of strong to weak positive (Vsh > Vsv) and negative (Vsv > Vsh) radial anisotropy in the crust. We observe negative radial anisotropy in the upper crust that is associated mainly with the location of a previously reported mantle plume. The anisotropy could be attributed to the vertical alignment of fossil microcracks or metamorphic foliations due to the upwelling of plume material. A strong positive radial anisotropy is centered at the location of an inferred boundary between the Congo Craton and the Oubanguides Belt that might be related to the preferred orientation of crustal anisotropic minerals associated with shearing in this fault zone. The middle crust is characterized by a widespread negative radial anisotropy that is likely caused by the flow-induced alignment of anisotropic minerals that crystallized during magma intrusion. The magnitude of the radial anisotropy varies systematically from predominantly negative in the middle crust to positive in the lower crust. The imaged patterns of the isotropic velocity and radial anisotropy are consistent with previous studies and agree with regional tectonics.

    In spite of the availability of substitutes for lead compounds used in paints, manufacturers continue to produce these paints for decorative and industrial applications. We report here on the concentration of lead in new paint sold in Cameroon and provide a summary of labeling practices on paints available in the country, based on a market survey. Investigators visited 76 retail and wholesale paint suppliers in Cameroon to collect information from paint product labels and to collect samples of paints to analyze for lead content. Only 8.5% of paints had labels identifying any of the ingredients, and none of the lead paints included any warning language. Based on a convenience sample (weighted to include multiple colors from the most common brands), 61 mostly enamel paints were purchased from retail outlets and analyzed for lead content (median: 2150 ppm; range: <21-500,000 ppm). Sixty-six percent of the new paint samples had concentrations exceeding the U.S. standard of 90 ppm total lead. All but one of the samples with lead concentrations greater than 90 ppm were also greater than 600 ppm. The largest manufacturer in the country-Seigneurie, a subsidiary of the U.S.-based company PPG-had significant lead concentrations in 9 out of 22 (41%) paints tested. There is an immediate need to adopt mandatory standards to limit the lead content of paint manufactured, imported, and sold in the country. To promote safer paint products we recommend the development of a third-party certification program for paints without added lead. These recommendations are consistent with the objectives of the Global Alliance to Eliminate Lead Paint established under the auspices of the United Nations to address this problem on a global scale.

    RATIONALE: The social marketing of STD treatment may be a strategy to increase the availability of effective therapy for urethritis in male patients. OBJECTIVE: To evaluate a pilot project of social marketing of urethritis treatment packages. The project, initially designed for over the counter sale in private pharmacies, was finally restricted by national health authorities to primary healthcare settings in Yaounde and Douala, Cameroon. METHODS: Monthly sales of packages containing antibiotics, condoms, partner referral cards, and written information on STDs were monitored by the social marketing agency. Structured interviews were conducted with a sample of traceable patients who had consulted for urethritis. Structured interviews completed by focus group discussions were conducted among healthcare providers. Interview findings were further validated by a "mystery patient" survey, using surrogate patients. Lastly, 15 key informants among the decision markers involved in the project were interviewed in depth. Local independent consultants carried out the whole evaluation. RESULTS: A total of 1392 treatment packages were sold in 10 months. Patients who had purchased the package reported high compliance with the treatment, with 99% taking the single dose of cefuroxime-axetil and 83% completing the course of doxycycline. 76% notified all or some partners, and 84% of those who had sex during treatment used condoms. In contrast, only 27% of trained healthcare providers prescribed "MSTOP". They questioned the omission of laboratory diagnosis, the selection of antibiotics, and the duration of therapy. Public health authorities were also sceptical about the choice of antibiotics and viewed the initial project as an overt encouragement of self medication. CONCLUSIONS: Although the MSTOP project was not implemented in the way it had initially been designed, it highlighted the patients' interest in the product. Public health authorities in Cameroon should have been made aware

    Mycobacteria cause major diseases including human tuberculosis, bovine tuberculosis and Johne’s disease. In livestock, the dominant species is M. bovis causing bovine tuberculosis (bTB), a disease of global zoonotic importance. In this study, we estimated the prevalence of Mycobacteria in slaughter cattle in Cameroon. A total of 2,346 cattle were examined in a cross-sectional study at four abattoirs in Cameroon. Up to three lesions per animal were collected for further study and a retropharyngeal lymph node was collected from a random sample of non-lesioned animals. Samples were cultured on Lowenstein Jensen media and the BACTEC MGIT 960 system, and identified using the Hain® Genotype kits. A total of 207/2,346 cattle were identified with bTB-like lesions, representing 4.0% (45/1,129), 11.3% (106/935), 23.8% (38/160) and 14.8% (18/122) of the cattle in the Bamenda, Ngaoundere, Garoua and Maroua abattoirs respectively. The minimum estimated prevalence of M. bovis was 2.8% (1.9–3.9), 7.7% (6.1–9.6), 21.3% (15.2–28.4) and 13.1% (7.7–20.4) in the four abattoirs respectively. One M. tuberculosis and three M. bovis strains were recovered from non-lesioned animals. The high prevalence of M. bovis is of public health concern and limits the potential control options in this setting without a viable vaccine as an alternative. PMID:27075056

    We investigated the prevalence of β-lactamase genes and plasmid-mediated quinolone resistance (PMQR) determinants in 51 carbapenem-resistant Enterobacteriaceae (CRE) from five teaching hospitals in central China. The prevalence of carbapenem resistance in Enterobacteriaceae was 1·0% (51/5012). Of 51 CRE, 31 (60·8%) isolates were positive for one tested carbapenemase gene, while 10 (19·6%) were simultaneously positive for two tested carbapenemase genes. The positive rates of bla KPC-2, bla NDM-1, bla IMP-4, bla IMP-26 and bla IMP-8 were 54·9%, 17·6%, 11·8%, 11·8% and 3·9%, respectively. Of 10 CRE with two carbapenemase genes, three, five, one and one were positive for bla KPC-2 and bla IMP-4, bla KPC-2 and bla IMP-26, bla KPC-2 and bla IMP-8, and bla KPC-2 and bla NDM-1, respectively. Eight of nine bla NDM-1-positive isolates lacked carbapenemases by the modified Hodge test, while 27/28 isolates harbouring bla KPC-2 were positive for carbapenemases determined by this test; 41·2% of the CRE-positive isolates also harboured ESBL genes in various combinations (three and two positive for bla KPC-2 also carried bla DHA-1 and bla CMY-2). The positive rates of qnrS1, qnrA1, qnrB and aac-(6/)-Ib-cr in CRE were 25·5%, 9·8%, 23·5% and 15·7%, respectively. In particular, 7/9 isolates harbouring bla NDM-1 were positive for these quinolone resistance genes, of which five carried qnrS1 and two carried qnrS1 and qnrB4. All but two of 29 Klebsiella pneumoniae isolates were grouped into 20 clonal clusters by PFGE, with the predominant cluster accounting for four bla KPC-2-positive isolates distributed in the same hospital. We conclude that there is a high prevalence of bla NDM-1 and PMQR determinants in CRE isolates in central China. Multiple resistance determinants in various combinations co-exist in these strains and we report for the first time the co-existence of bla KPC-2 and bla IMP-26 in a strain of Klebsiella oxytoca.

    Despite free of charge biomedical treatment, the cost burden of Buruli ulcer disease (Bu) hospitalisation in Central Cameroon accounts for 25% of households' yearly earnings, surpassing the threshold of 10%, which is generally considered catastrophic for the household economy, and calling into question the sustainability of current Bu programmes. The high non-medical costs and productivity loss for Bu patients and their households make household involvement in the healing process unsustainable. 63% of households cease providing social and financial support for patients as a coping strategy, resulting in the patient's isolation at the hospital. Social isolation itself was cited by in-patients as the principal cause for abandonment of biomedical treatment. These findings demonstrate that further research and investment in Bu are urgently needed to evaluate new intervention strategies that are socially acceptable and appropriate in the local context.
