Investigating linkage to care following community-based screening for hepatitis B virus in rural Senegal: A mixed methods study.

This paper investigates linkage to care following community-based screening for hepatitis B virus (HBV) in rural Senegal. HBV-positive participants who completed a biological and clinical examination to assess liver disease and treatment eligibility were referred to a regional hospital (if eligible for treatment), invited to join the Sen-B research cohort study (adults with detectable viral load) or referred to their local health centre (all others). Logistic regressions were conducted to investigate factors associated with (i) uptake of the scheduled post-screening examination, and (ii) HBV management initiation.

Residual malaria transmission and the role of Anopheles arabiensis and Anopheles melas in central Senegal.

Understanding the behavior and ecology of local malaria vectors is essential for the effectiveness of the commonly used vector-targeted malaria control tools in areas of low malaria transmission. This study was conducted to determine species composition, biting behavior and infectivity of the major Anopheles vectors of Plasmodium falciparum in low transmission settings in central Senegal. Adult mosquitoes were collected using human landing catches during 2 consecutive nights and Pyrethrum Spray Catches in 30-40 randomly selected rooms, from July 2017 to December 2018 in 3 villages.

It causes differential diagnostic problems in the pediatric age group and there is no consensus on the therapeutic approach. We here report the case of a 1-month-old infant treated for respiratory distress syndrome.

Anopheles gambiae s.l. swarms trapping as a complementary tool against residual malaria transmission in eastern Gambia.

Malaria remains a major health problem and vector control is an essential approach to decrease its burden, although it is threatened by insecticide resistance. New approaches for vector control are needed. The females of Anopheles gambiae s.

Mapping the breeding sites of Anopheles gambiae s. l. in areas of residual malaria transmission in central western Senegal.

Despite the deployment of several effective control interventions in central-western Senegal, residual malaria transmission is still occurring in some hotspots. To better tailor targeted control actions, it is critical to unravel the underlying environmental and geographical factors that cause the persistence infection in hotspot villages. "Hotspots villages" were defined in our study as those reporting more than six indigenous malaria cases during the previous year.

Evaluation of the effectiveness of a targeted community-based IRS approach for malaria elimination in an area of low malaria transmission of the central-western Senegal.

The implementation of effective malaria control strategies in the central-western Senegal, such as Indoor Residual Spraying (IRS), long-lasting insecticide-treated nets (LLIN), Seasonal malaria chemoprophylaxis (SMC) and appropriate management of malaria cases, has led to the decline of malaria transmission in the region. However, residual malaria transmission still occurring in some localities, known as hotspots villages, making challenging the achievement of the malaria elimination goal. A pilot study was undertaken between 2013 and 2014 to test the feasibility of a community-based IRS approach for malaria elimination in four targeted health districts of the Central Western Senegal.

[Indications and results of surgical resection of bubbles arising from pulmonary emphysema].

Surgical resection of bubbles or bullectomy is the gold standard in the treatment of bubbles arising from pulmonary emphysema. It is usually indicated for patients with complicated bubbles or when they are the underlying cause of disabling dyspnea. This study aims to determine the indications for bullectomy and to evaluate surgical outcomes in our Department.

Traditional cooking practices and preferences for stove features among women in rural Senegal: Informing improved cookstove design and interventions.

Nearly half the world's population burns solid fuel for cooking, heating, and lighting. The incomplete combustion of these fuels is associated with detrimental health and environmental effects. The design and distribution of improved cookstoves that increase combustion efficiency and reduce indoor air pollution are a global priority.

Penetrating chest injuries caused by swordfish sword used as a weapon.

We report 5 cases of penetrating chest wounds caused by weapons made from swordfish swords, involving breakage of the sword that later appeared as a thoracic foreign body. The patients had been assaulted 2 days to 17 years earlier. Three of them had a chronic infected wound, one had a penetrating thoracic wound with hemopneumothorax, and one had a foreign body.

An epidemiological study to assess Plasmodium falciparum parasite prevalence and malaria control measures in Burkina Faso and Senegal.

Background: Malariometric information is needed to decide how to introduce malaria vaccines and evaluate their impact in sub-Saharan African countries.

Methods: This cross-sectional study (NCT01954264) was conducted between October and November, 2013, corresponding to the high malaria transmission season, in four sites with Health and Demographic Surveillance Systems (DSS) [two sites with moderate-to-high malaria endemicity in Burkina Faso (Nouna and Saponé) and two sites with low malaria endemicity in Senegal (Keur Socé and Niakhar)]. Children (N = 2421) were randomly selected from the DSS lists of the study sites and were stratified into two age groups (6 months-4 years and 5-9 years).

[Social Determinants of Routine Immunization Coverage of Children Aged 12 to 23 Months in the Kaolack Region of Senegal].

Introduction: The lowest immunization coverages (IC) are recorded in Africa, where health systems fail to take geographical disparities into account. The objective of this study was to identify the social determinants of routine immunization coverage for children aged 12 to 23 months in the Kaolack region.Methodology: A cross-sectional, descriptive and analytical study was conducted in four health districts of Kaolack region from 1 to 30 June 2014.

[Anatomical bases of external pudendal artery injuries during surgical treatment of pelvic limb varices].

Introduction: External pudendal artery is a collateral branch of the common femoral artery which is the primary blood supply to the penis or the clitoris. Its relationship with the venous arch of the great saphenous vein and its afferents in femoral triangle, are very narrow. This often entails injuries during crossectomy and great saphenous vein stripping.

Materials And Method: We injected a dye into the subpleural lymphatic vessels in 65 right lung segments, followed by dissection in 22 subjects.

Results: At the upper lobe, we had injected 32 segments.

Ethical Challenges and Lessons Learned During the Clinical Development of a Group A Meningococcal Conjugate Vaccine.

Background: The group A meningococcal vaccine (PsA-TT) clinical development plan included clinical trials in India and in the West African region between 2005 and 2013. During this period, the Meningitis Vaccine Project (MVP) accumulated substantial experience in the ethical conduct of research to the highest standards.

Methods: Because of the public-private nature of the sponsorship of these trials and the extensive international collaboration with partners from a diverse setting of countries, the ethical review process was complex and required strategic, timely, and attentive communication to ensure the smooth review and approval for the clinical studies.

A Case Report of Iatrogenic Pulmonary Artery Injury due to Chest-Tube Insertion Repaired under Cardiopulmonary Bypass.

The authors presented a case of a 50-year-old patient with multiple trauma who suffered from the inadvertent cannulation of the main pulmonary artery at the second attempt of left chest drainage. Pulmonary artery injury has been suspected because early chest tube production was 2300 mL of blood. CT scan showed injury of the trunk of the pulmonary artery, left hemothorax, and suspect damage of the right branch of the pulmonary artery.

The azygos lobe: an unusual anatomical observation with pathological and surgical implications.

The azygos lobe is a rare anomaly in broncho-pulmonary segmentation due to an unusual course of the azygos vein. Its radiological aspects are well known but there are few anatomical reports about its bronchial and vascular components. The authors describe the characteristic features in a particular case of the azygos lobe observed in the right lung after studying a fresh specimen and doing a casting of said specimen.

Emergence and distribution of the ilioinguinal nerve in the inguinal region: applications to the ilioinguinal anaesthetic block (about 100 dissections).

The variations in the emergence and distribution of the ilioinguinal nerve are the cause of the failures of the ilioinguinal block and the difficulties at interpreting the ilioinguinal nerve syndrome. In order to identify its variations and set reliable anatomical landmarks for performing the ilioinguinal block, we dissected 100 inguinal regions of 51 adult corpses. The nerve was absent in seven cases and double in one case.

Arteriography of three models of gastric oesophagoplasty: the whole stomach, a wide gastric tube and a narrow gastric tube.

The esogastric anastomotic fistula,occurring after the replacement of esophagus by the stomach, is a post-operative complication always feared and awaited. Apart from other causes, there exist the anatomical dispositions notably the vascular and technical factors that stress this potential risk despite certain advantages of esophagogastroplasty. The goal of our study was to study the arterial distribution of the gastric transplants in order to identify the better modalities of their making.
