Funiculars anomalies during childbirth: about 562 cases collected in Pikine National Hospital

Background: Establish an epidemiological description of the different types of umbilical cord anomalies in our reference structure and to assess their impact on the prognosis of childbirth.Methods: We conducted a descriptive study, cross over a period of one year in Obstetrics and Gynecology Service Level III of Pikine Hospital. We included all women in labor have reached the term less than 28 weeks gestation and delivering a newborn with umbilical cord abnormality diagnosed during labor or during the expulsion.Results: During this period, we compiled 562 anomalies of the umbilical cord, which gave a frequency of 23.8%. Length discrepancies were far the most frequent (67.4%). Only the prolapsed cord was an independent risk factor for cesarean section (p = 0.036). The rate of episiotomy and tear was significantly higher in case of brevity (primitive or induced) cord (p = 0.042). Apgar score ≤7 was significantly related to the presence of brevity (p = 0.000), excessive length (p = 0.048) or cord prolapse (p = 0.037).Conclusions: This study has allowed us to see that the funicular abnormalities impede the smooth running of childbirth. Their occurrence is facilitated by the excess amniotic fluid, prematurity and low birth weight. Their research during prenatal ultrasounds should be systematic

Evaluation of the Prognostic Value of IFN-γ Release Assay and Tuberculin Skin Test in Household Contacts of Infectious Tuberculosis Cases in Senegal

BACKGROUND: Chemoprophylaxis of contacts of infectious tuberculosis (TB) cases is recommended for TB control, particularly in endemic countries, but is hampered by the difficulty to diagnose latent TB infection (LTBI), classically assessed through response to the Tuberculin Skin Test (TST). Interferon-gamma release assays (IGRA) are proposed new tools to diagnose LTBI, but there are limited data on their ability to predict the development of active TB disease. To address this, we investigated the response to TST and IGRA in household contacts of infectious TB cases in a TB high-burden country and the potential correlation with development of TB. METHODOLOGY/PRINCIPAL FINDINGS: Prospective household contacts study conducted in two health centres in Dakar, Senegal. A total of 2679 household contacts of 206 newly detected smear and/or culture positive index TB cases aged 18 years or greater were identified A TST was performed in each contact and an ESAT6/CFP10 ELISPOT assay performed in a random sample of those. Contacts were followed-up for 24 months. TB was diagnosed in 52 contacts, an incidence rate of 9.27/1000 person-years. In univariable analysis, the presence of positive TST (> or = 10 mm) and ELISPOT (>32 SFC/million PBMC) responses at baseline were associated with active TB during follow-up: Rate Ratio [RR] = 2.32 (95%CI:1.12-4.84) and RR = 2.09 (95%CI:0.83-5.31), respectively. After adjustment for age, sex and proximity to index case, adjusted RRs were 1.51 (95%CI:0.71-3.19) and 1.98 (95%CI:0.77-5.09), respectively. Restricting analysis to the 40 microbiologically confirmed cases, the adjusted RR for positive ELISPOT was 3.61 (95%CI:1.03-12.65). The median ELISPOT response in contacts who developed TB was 5-fold greater than in those who did not develop TB (p = 0.02). CONCLUSIONS/SIGNIFICANCE: TST and IGRAs are markers of a contact of the immune system with tubercle bacilli. In a TB endemic area, a high ELISPOT response may reflect increased bacterial replication that may subsequently be associated with development of TB disease and may have a prognostic value. Further longitudinal data are needed to assess whether IGRAs are reliable markers to be used for targeting chemoprophylaxis

Ecology of Phlebotomine Sand Flies in the Rural Community of Mont Rolland (Thiès Region, Senegal): Area of Transmission of Canine Leishmaniasis

BACKGROUND: Different epidemiological studies previously indicated that canine leishmaniasis is present in the region of Thiès (Senegal). However, the risks to human health, the transmission cycle and particularly the implicated vectors are unknown. METHODOLOGY/PRINCIPAL FINDINGS: To improve our knowledge on the population of phlebotomine sand flies and the potential vectors of canine leishmaniasis, sand flies were collected using sticky traps, light traps and indoor spraying method using pyrethroid insecticides in 16 villages of the rural community of Mont Rolland (Thiès region) between March and July 2005. The 3788 phlebotomine sand flies we collected (2044 males, 1744 females) were distributed among 9 species of which 2 belonged to the genus Phlebotomus: P. duboscqi (vector of cutaneous leishmaniasis in Senegal) and P. rodhaini. The other species belonged to the genus Sergentomyia: S. adleri, S. clydei, S. antennata, S. buxtoni, S. dubia, S. schwetzi and S. magna. The number of individuals and the species composition differed according to the type of trap, suggesting variable, species-related degrees of endophily or exophily. The two species of the genus Phlebotomus were markedly under-represented in comparison to the species of the genus Sergentomyia. This study also shows a heterogeneous spatial distribution within the rural community that could be explained by the different ecosystems and particularly the soil characteristics of this community. Finally, the presence of the S. dubia species appeared to be significantly associated with canine leishmaniasis seroprevalence in dogs. CONCLUSIONS/SIGNIFICANCE: Our data allow us to hypothesize that the species of the genus Sergentomyia and particularly the species S. dubia and S. schwetzi might be capable of transmitting canine leishmaniasis. These results challenge the dogma that leishmaniasis is exclusively transmitted by species of the genus Phlebotomus in the Old World. This hypothesis should be more thoroughly evaluated

PHYSICAL CHARACTERIZATION OF EXCAVATED

The building is an object of concern in terms of health, energy consumption and environmental impacts. With more than 40 % of the worlds energy consumption and high CO2 emissions, the building sector is among the most energy-intensive sectors. An in-depth analysis of the building sector shows that Concrete, the material currently most used in Senegal is unsuited to the climatic conditions of Sahelian countries. In addition, cement production consumes a lot of energy and is a source of greenhouse gas emissions. Faced with environmental and energy concerns, the choice of appropriate materials is a key to limiting environmental impact and ensuring a healthy and comfortable indoor environment. This is how a sustainable approach using local clay resources for the production of clay bricks was implemented. However, the use of swelling clays is the source of significant problems in construction. Thus for a good prediction of the mechanical and thermal behavior of a material, it is important to determine its physical properties. This is why our study focuses on the physical characterization of the excavated soils of Diamniadio

Prevalence and risk factors of chronic kidney disease in an african semi-urban area: Results from a cross-sectional survey in Gueoul, Senegal

Chronic kidney disease (CKD) is a public health priority worldwide; however, its prevalence and incidence are difficult to assess. In Africa, few studies have been conducted on the prevalence of CKD. This study sought to describe the epidemiological characteristics and profile of CKD, as well as the related risk factors in Guéoul, a semi-urban zone in Senegal. An observational, cross-sectional, and descriptive study was conducted in Guéoul city in Senegal from November 1, 2012, to December 10, 2012, according to the WHO STEPS approach. People older than 35 years living in Guéoul city were included in the study. Cardiovascular and renal disease risk factor screening was conducted for this population. Data were analyzed using the 3.5.1 version of Epi Info software. The significance level was a P <0.05. One thousand four hundred and eleven participants with a mean age of 48 ± 12.68 years and a sex ratio of 0.34 were included in the study (359 men/1052 women). The prevalence of renal disease was 36.5%. Sixty-eight people showed proteinuria greater than two cross with urinary dipsticks. Two hundred and six people had a glomerular filtration rate <60 mL/min, and among them, 201 were in stage III, two in stage IV, and three in stage V according to the modification of diet in renal disease formula. Ninety-eight participants had morphological abnormalities. Cardiovascular risk factors found among participants with renal disease were obesity (25.2%), hypertension (55.5%), diabetes (2.3%), and renal and metabolic syndrome (32.43%). Those that statistically significantly correlated with renal disease were obesity (P = 0.0001), hypertension (P = 0.0001), and diabetes (P = 0.021). This study assessed the extent of renal disease in the population of Guéoul city. Being aware of the prevalence of CKD in the general population of Senegal is mandatory for defining appropriate strategies for the management of these risk factors and progression of renal diseases
