[Telomeres and lung]. / Télomères et poumon.

Genetic studies of familial forms of interstitial lung disease (ILD) have led to the discovery of telomere-related gene (TRG) mutations (TERT, TERC, RTEL1, PARN, DKC1, TINF2, NAF1, NOP10, NHP2, ACD, ZCCH8) in approximately 30% of familial ILD forms. ILD patients with TRG mutation are also subject to extra-pulmonary (immune-hematological, hepatic and/or mucosal-cutaneous) manifestations. TRG mutations may be associated not only with idiopathic pulmonary fibrosis (IPF), but also with non-IPF ILDs, including idiopathic and secondary ILDs, such as hypersensitivity pneumonitis (HP). The presence of TRG mutation may also be associated with an accelerated decline of forced vital capacity (FVC) or poorer prognosis after lung transplantation, notwithstanding which, usual ILD treatments may be proposed. Lastly, patients and their relatives are called upon to reduce their exposure to environmental lung toxicity, and are likely to derive benefit from specific genetic counseling and pre-symptomatic genetic testing.

[Ensuring continuity of care at the time of COVID-19: challenges for the Dakar Integrated Support Center for Addictions]. / Assurer la continuité des soins au temps de la COVID-19 : défis pour le centre de traitement des addictions à Dakar.

The COVID-19 pandemic has an impact on health systems, whose modes of adaptation and response on the ground are still poorly documented and are evolving. The Dakar Integrated Support Center for Addictions (CEPIAD) has been implementing risk reduction since 2014, particularly with drug users. The COVID-19 pandemic and related public health measures were an obstacle to its attendance by patients, in particular due to movement restriction. In addition to the implementation of individual and collective preventive measures in the center, CEPIAD has experimented "take-home" for methadon that is generally provided daily through directly observed treatment. The center has also taken care of amnestied incarcerated cannabis users. Several aspects of this experience, perceived positively, could be relevant outside the pandemic context.

Estimation of the burden of flu-association influenza-like illness visits on total clinic visits through the sentinel influenza monitoring system in Senegal during the 2013-2015 influenza seasons.

Knowing the burden of influenza is helpful for policy decisions. Here we estimated the contribution of influenza-like illness (ILI) visits associated with laboratory-confirmed influenza among all clinic visits in a Senegal sentinel network. ILI data from ten sentinel sites were collected from January 2013 to December 2015. ILI was defined as an axillary measured fever of more than 37.5 °C with a cough or a sore throat. Collected nasopharyngeal swabs were tested for influenza viruses by rRT-PCR. Influenza-associated ILI was defined as ILI with laboratory-confirmed influenza. For the influenza disease burden estimation, we used all-case outpatient visits during the study period who sought care at selected sites. Of 4030 ILI outpatients tested, 1022 were influenza positive. The estimated proportional contribution of influenza-associated ILI was, per 100 outpatients, 1.2 (95% CI 1.1-1.3), 0.32 (95% CI 0.28-0.35), 1.11 (95% CI 1.05-1.16) during 2013, 2014, 2015, respectively. The age-specific outpatient visits proportions of influenza-associated ILI were higher among children under 5 years (0.68%, 95% CI: 0.62-0.70). The predominant virus during years 2013 and 2015 was influenza B while A/H3N2 subtype was predominant during 2014. Influenza viruses cause a substantial burden of outpatient visits particularly among children under 5 of age in Senegal and highlight the need of vaccination in risk groups.

Physical, mental and social consequences in civilians who have experienced war-related sexual violence: a systematic review (1981-2014).

OBJECTIVES: To identify the health outcomes of sexual violence on civilians in conflict zones between 1981 and 2014. STUDY DESIGN: Systematic review. METHODS: For the purpose of this study, we defined sexual violence as sexual torture including, individual rape, gang rape, and sexual slavery. All types of conflicts were included (intrastate, interstate, and internationalized intrastate). Quantitative and mixed-method studies, reporting any physical, mental, and social consequences, were retrieved from Medline, Embase, Global Health, Global Health Library, WHOLIS, Popline, and Web of Sciences (n = 3075) and from checking reference lists and personal communications (n = 359). Data were analyzed using Microsoft Excel and MetaXL. Given inherent variation, the means derived from combining studies were misleading; thus, we focused on the range of values. RESULTS: The 20 studies were from six countries, five in Africa (18 studies), and especially in Democratic Republic of Congo (12 studies). The number of subjects varied from 63 to 20,517, with 17 studies including more than 100 subjects. Eight studies included males. Gang rape, rape, and abduction were the most commonly reported types of sexual violence. Sixteen studies provided data on physical outcomes of which the most common were pregnancy (range 3.4-46.3%), traumatic genital injuries/tears (range 2.1-28.7%), rectal and vaginal fistulae (range 9.0-40.7%), sexual problems/dysfunction (range 20.1-56.7%), and sexually transmitted diseases (range 4.6-83.6%). Mental health outcomes were reported in 14 studies, the most frequent being post-traumatic stress disorder (range 3.1-75.9%), anxiety (range 6.9-75%), and depression (range 8.8-76.5%). Eleven studies provided social outcomes, the most common being rejection by family and/or community (range of 3.5-28.5%) and spousal abandonment (range 6.1-64.7%). CONCLUSIONS: Wartime sexual violence is highly traumatic, causing multiple, long-term negative outcomes. The number and quality of studies published does not match the significance of the problem. The findings highlight the need for care of the survivors and their relatives and raise concerns about how they and their children will be affected in the long term.

Usefulness of Dried Blood Spots (DBS) to perform hepatitis C virus genotyping in drug users in Senegal.

The aim of this pilot study was to analyze the Hepatitis C Virus (HCV) genotypes circulating in Senegal among Drug User (DUs), using Dried Blood Spots (DBS) as RNA source for molecular assays. Heroin and/or cocaine users (n = 506) were recruited in Dakar from April to July 2011, using a Respondent Driven Sampling (RDS) method. DBS preparation consisted of five drops of whole blood from finger applied to a Whatman paper card. HCV infection was screened by the detection of anti-HCV antibodies, using a rapid immune-chromatographic test. HCV RNA was quantified on anti-HCV positive DBS, using the Abbott RealTime HCV® Genotyping was performed on DBS with detectable viral load with Versant® HCV Genotype 2.0 Assay (LiPA) and Abbott RealTime HCV Genotype II assay®. Among the 506 participants, 120 were tested as positive for anti-HCV antibodies and their samples were analyzed for HCV RNA viral load and genotype. Out of the 120 DBS tested, HCV RNA was detected on 25 (20.8%). The median viral load was 15,058 IU/ml (ranging from 710 to 766,740 IU/ml). All positive DBS were suitable for the genotyping assay, that showed a predominance of genotype 1 (21/25) including 16 genotypes 1a and 5 genotypes 1b. HCV genotype 1 prevails in a DU population in Dakar. DBS could be useful for HCV RNA genotyping, but optimal storage conditions should required avoiding RNA impairment. Acknowledging this limitation, DBS could be a great interest for detecting and genotyping HCV viremic patients. J. Med. Virol. 89:484-488, 2017. © 2015 Wiley Periodicals, Inc.

[Malignant infantile osteopetrosis revealed by choanal atresia: A case report]. / Ostéopétrose maligne infantile révélée par une atrésie des choanes : à propos d'un cas.

Malignant infantile osteopetrosis is a rare genetic disease characterized by increased bone density due to osteoclastic dysfunction. We report on the case of a 3-month-old girl who was referred to our hospital by the ENT department for severe anemia in the context of bilateral choanal atresia. Clinical examination showed failure to thrive, anemia, respiratory distress, bilateral choanal atresia, and chest deformation. The abdomen was soft with large hepatosplenomegaly. We noted a lack of eye tracking, no optical-visual reflexes, and left nerve facial paralysis. The blood count showed normocytic normochromic anemia with severe thrombocytopenia. The infectious work-up and blood smears were negative. The skeleton X-ray showed diffuse bone densification of the skull, long bones, pelvis, vertebrae, and ribs. The facial bone CT confirmed membranous choanal atresia. The molecular biology search for the TCIRG1 gene mutation was not available. The patient had supportive treatment (transfusion, oral steroid, vitamin D, oxygen, nutrition). Bone marrow transplantation was indicated but not available. She died at 6 months in a context of severe anemia and bleeding. Malignant infantile osteopetrosis is rare and symptoms are nonspecific. Diagnosis should be considered in young infants presenting refractory anemia, particularly in the context of choanal atresia. Bone marrow transplantation remains the only curative treatment.

[Particularities of liver abscesses in children in Senegal: Description of a series of 26 cases]. / Particularités des abcès du foie chez l'enfant au Sénégal : description d'une série de 26 cas.

UNLABELLED: Liver abscess is a serious infection that can cause life-threatening complications. OBJECTIVE: To describe the epidemiology, diagnosis, and progression of liver abscess at the Dakar National Albert-Royer Children's Hospital. METHOD: A retrospective study was conducted from over a period of 5 years (1st January 2010 to 31st December 2014). All children aged 0-15 years hospitalized for liver abscess with ultrasound confirmation were included. We collected demographic data (age, gender, socioeconomic status, origin), clinical data (general and hepatic symptoms), diagnostic data (ultrasound, bacteriology) and progression (death, complications, sequelae). The data were analyzed with Epi-info (P<0.05 was considered significant). RESULTS: We collected 26 cases of liver abscesses, representing a hospital prevalence of 100 cases per 100,000 admissions. Males predominated (sex ratio: 1.36). The children's average age was 7.2 years. Most of the children came from urban areas of Dakar. Low socioeconomic status and precarious lifestyle were the contributing factors. Anemia (69.2%), malnutrition (42.3%), and abdominal trauma (15.3%) were the main causes found. The Fontan triad characteristic of the liver abscess was found in 57.7% of cases. At ultrasound, a single abscess was found in 21 cases. The abscess was located in the right lobe in 18 cases, the left lobe in three cases, and in both lobes in three cases. Segment VI (four cases) was the most frequently involved. Bacteriologically, the abscess was pyogenic in 17 cases and an amoebic abscess in nine cases. The main pyogenic sources found were Klebsiella pneumoniae in two cases, Pseudomonas aeruginosa in one case, Streptococcus pneumoniae in one case, and Staphylococcus aureus in one case. The average duration of antibiotic treatment was 14.5 days. Liver drainage was carried out in 24 cases. The outcome was favorable in all children. CONCLUSION: The prevalence of liver abscesses at the Albert-Royer Children's Hospital is relatively high, compared to the literature data. Percutaneous drainage combined with antibiotics remains the treatment of choice. The prognosis is favorable.

Pediatric invasive pneumococcal disease in Senegal.

OBJECTIVES: We aimed to describe the clinical, epidemiological, and outcome characteristics of IPD case patients hospitalized at the Albert-Royer National Children's Hospital (French acronym CHNEAR) to evaluate the disease burden of IPDs in a pediatric hospital of Dakar (Senegal). PATIENTS AND METHODS: All children aged 0-15 years hospitalized at the CHNEAR between January 1st, 2008 and December 31st, 2013 for a documented IPD were included in the study. Medical history, risk factors, clinical, bacteriological, and outcome data was collected. Data was then analyzed using the SPSS software, version 16 (Pearson's Chi(2) test: a P-value<0.05 was considered statistically significant). RESULTS: A total of 218 IPD patients were hospitalized at the CHNEAR during the study period (hospital prevalence: 0.79%). The mean age was 36.1 months. The male to female ratio was 1.27 (122 boys and 96 girls). Infants<2 years of age represented 61.46% of patients. Prior antibiotic therapy was found in 54% of patients but details were lacking. Infection sites were mostly meningeal (61%) and pleuropulmonary (28.9%). The main isolated serotypes were 1, 6A, 14, 5, and 23F. Case fatality was 17.4% and it was five times higher for pneumococcal meningitis. CONCLUSION: IPDs are very common in children in Senegal. Infants<2 years of age are particularly affected. The very high case fatality (17%) was significantly associated with meningeal infection sites hence the need for better access to pneumococcal vaccines.

[Influenza sentinel surveillance network improvement in Senegal and results]. / Renforcement du réseau de surveillance sentinelle de la grippe au Sénégal et résultats.

Influenza surveillance in Senegal was initially restricted to the identification of circulating strains. The network has recently been enhanced (i) to include epidemiological data from Dakar and other regions and (ii) to extend virological surveillance to other respiratory viruses. Epidemiological data from the sentinel sites is transmitted daily by mobile phone. The data include those for other febrile syndromes similar to influenza-like illnesses (ILI), corresponding to integrated approach. Also, clinical samples are randomly selected and analyzed for influenza and other respiratory viruses. There were 180,192 declared visits to the 11 sentinel sites between week 11-2012 and week 52-2013; 24% of the visits were for fever syndromes and 25% of the cases of fever syndrome were ILI. Rhinoviruses were the most frequent cause of ILI (19%), before adenoviruses (18%), enteroviruses (18%) and influenza A viruses (13%). Co-circulation and co-infection were frequent and were responsible for ILI peaks. In conclusion, it is clear that the greatest advantage of this system is the ease with which it can be implemented, thanks to the availability of mobile phones and mobile phone networks. We recommend this solution for other African countries, because it performs very well and provides rapid benefits in terms of public health decision-making.

[Elimination of maternal and neonatal tetanus in Senegal: evolution of survey indicators of 2003-2009]. / Élimination du tétanos maternel et néonatal au Sénégal : évolution des indicateurs de surveillance de 2003 à 2009.

OBJECTIVES: This study aimed to estimate the evolution of the maternal and neonatal tetanus in Senegal from the tetanus vaccination coverage among pregnant women, the proportion of deliveries attended by trained medical personnel and the number of cases of tetanus declared by respective districts, helping to identify districts at high risk of neonatal tetanus (NNT). METHOD: Data analysis of the epidemiological surveillance realized from 2003 to 2009 in 65 districts of Senegal. Data were collected from the reports of vaccination usage and from the Statistical Directories of the National Health Information Services of the Ministry of Health & Prevention. A district is at high risk when the incidence of NNT is ≥1 case per 1 000 Live births (LB). RESULTS: There were 153 reported cases of NNT in Senegal between 2003 and 2009. National incidence decreased from 0.08 to 0.03 case per 1 000 LB (p = 0,0008). The vaccination coverage of the pregnant women by at least two doses of tetanus vaccine (VAT2+) increased from 66% in 2003 to 78% in 2009. The percentage of districts that had reached a vaccination coverage ≥80% was 20% in 2003 compared to 60% in 2009 (p = 0.009). The proportion of deliveries attended by qualified medical staff evolved from 53% in 2003 to 67% in 2009 (p = 0,02). By 2009, the incidence of NNT was less than 1 case per 1,000 LBs in all districts. CONCLUSION: Assessing the elimination of maternal and neonatal tetanus in Senegal shows that progress has been made from 2003 to 2009. This was made possible through the organization of vaccination campaigns for women of childbearing age and the improvements in the conditions of deliveries.

[Role of eldest in a destructured family context: clinical case report from Fann Hospital in Dakar, Senegal]. / La position d'aîné a l'epreuve d'un contexte familial déstructurant: une observation au CHU de Fann a Dakar.

In a Senegalese family, the role of the eldest, i.e. the one who must lead the way, is particularly difficult. The eldest is the only one required to excel and wield power in the family. To ensure his status and maintain his identity, the elder must be acknowledged as such by the father, mother, and younger siblings. The purpose of this report is to describe a case demonstrating the psychological frailness associated with elder status. The patient developed depressive breakdown when his mother dismayed by his professional failure ceased to acknowledgement his status and implicitly disqualified him. Discussion includes the psychopathological dimension revolving mainly around an Oedipal relationship with the father.

[Factors determining the place of delivery in women who attended at least one antenatal consultation in a health facility (Senegal)]. / Facteurs déterminant le lieu d'accouchement chez des femmes ayant bénéficié au moins d'une consultation prénatale dans une structure sanitaire (Sénégal).

BACKGROUND: Home birth remains a major cause of maternal and neonatal deaths in Senegal. The objective of this study was to identify the determinants of home birth in women who attended at least one antenatal consultation during their last pregnancy. METHOD: The study was cross-sectional and analytical. It covered a sample of 380 women selected at random among those who have given birth in the last 12 months in the health district Gossas. Data were collected at home using a questionnaire during an interview after informed consent. Multiple logistic regression was used to explore the determinants of childbirth at home using the Andersen model. RESULTS: The mean age was 26.2 ± 6.1 years. Women were married (97.3%), illiterate (81.8%) and lived in rural areas (78.4%). Available means of transportation at home were car (7.6%), cart (62.9%) or none 29.5%. In addition, 52.2% of the women lived more than 5 km from a health facility. For 59.0% of the women, the prenatal exam was considered satisfactory. The prevalence of home birth was 24%. Factors related to birth at home are polygamous marriage (OR=2.04 [1.13-3.70]), lack of transportation (OR=2.11 [1.13-5.01]) and residence more than 5 km from a health facility (OR=2.68 [1.56-4.16]). Late (3.90 [2.30-6.65]) or low quality (4.27 [2.25-8.10]) prenatal exams were also risk factors. CONCLUSION: Home birth is linked to access to health facilities but also to the prenatal consultation. Particular emphasis should be placed on training health care providers to improve the quality of the patients in the structures.

[Clinical and psychopathological postpartum depression: eleven Senegalese cases report]. / Aspects cliniques et psychopathologiques de la dépression du postpartum: rapport d'une série de onze cas sénégalais.

INTRODUCTION: The postpartum depression is a frequent puerperium psychiatric disorder. The authors study the clinical, therapeutic and evolutionary aspects of the postpartum depression among eleven Senegalese women. MATERIAL AND METHOD: They examined the medical reports and hospital registers of eleven patients belonging to a sample of 52 women presenting psychic disorders of the puerperality. The diagnosis was made by using the International Classification of the Diseases. RESULTS: The symptoms of depression were irritability, bad concentration, multiple somatic complaints, of insomnia of drowsiness, loss of the usual interests. All the patients profited from psychotherapy and have received chemotherapy with antidepressant treatment associated tranquillizing in six cases. They improved from 29 to 43 days after their admission. CONCLUSION: The pregnancy and the childbirth, the parity, personal history of the patient, their social environment and the cultural representations of maternity are factors of depression of the postpartum. The antidepressant is always essential in the treatment.

[Caries patterns and diet in early childhood caries]. / Le regime alimentaire et la distribution topographique des lesions de caries précoces de l'enfance.

INTRODUCTION: Early childhood caries (EEC) are multiple carious lesions affecting the primary teeth of infants and preschool children. They are related to a prolonged and night bottle-feeding rich in fermentable carbohydrates. The carious lesions characterised by their patterns and the rapidity of their process can lead to a widespread tooth destruction. The aim of this study was to evaluate the patterns of the carious lesions and their relationship to the diet. MATERIAL AND METHOD: This prospective study was carried out in Dakar in public heath structures that have a dental office. It has included 68 children of both sex aged from two to 6 years consisted of 35 boys (51% of the sample) and 33 girls (49%) with the predominance of the 5-year-old children. These children were examined using a plan mouth mirror and probes and their mothers were interviewed. RESULTS: The observed carious lesions were distributed on all tooth surfaces but the complete coronal destruction was the most common lesions observed and represented 25 of the lesions, followed by lesions in three faces of the tooth (17%). The most frequently affected tooth was the association maxillar incisors and molars and the mandibular molars (32.4%). The incisor alone represented 22.1% of the affected teeth. The children were breast-fed associated with either pap or with hard food (52.9%). The bottle was added to this association in 32.4% of the cases and 10% of the children were exclusively breast-fed. The carious lesions were more severe and more frequent in children fed with breast associated with pap and hard food and in those fed with breast associated with the bottle pap and food than to children exclusively breast-fed. These differences were not statistically significant (p = 0.73 > 0.05). CONCLUSIONS: Early childhood caries are related to a diet rich in carbon hydrate. They lead to severe tooth destruction. The treatments cost are very high thus prevention by information on the bad effects of sugar on diet and the baby bottle are of great interest.

[Evaluation of oral health and access to care in senegalese children with Down syndrome: preliminary study]. / Evaluation de la santé oro- faciale et de l'accès aux soins chez des enfants sénégalais porteurs de la trisomie 21: etude préliminaire.

Down syndrom is the most frequent genetic disease discribed for viable (live born) children and the commonest cause of mental deficiency in developed countries. It is an autosomal chromosomic anomaly resulting from trisomy of all or part of chromosome 21 and is characterizd by general and mental deficiencies and a typical facial phenotype. The aims of this study are:--to evaluate the general and oral health of a senegalese group of children with Down syndrome and their siblings the closest in age,--to assess their access to care. We used the OADS (Oral Assessment Down Syndrome) questionnaire in 25 senegalese children with Down syndrome living in Dakar and 17 od their siblings the closest in age. Their ages range from 4 to 20 years old in both groups. Our results revealed that senegalese children with Down syndrome have more general and oral health problems compared to their siblings the closest in age but they were more likely to have difficulty finding both medical and dental services. This study pointed out the need for special care services with trained people for a better management of these specific patients.

[Study of fear of dental treatments in pediatrics in Sénegal]. / Etude de la peur liée aux soins dentaires chez l'enfant au Sénégal.

Fear and anxiety of dental treatment have been recognized as a major source of a problems in pediatric dentistry. They can prevent dental procedure and lead to avoidance an dental phobia. A variaty of studies, using psychometric methods have been carried out worldwide to evaluate these behavious. In Senegal, no study of this nature has been done yet. The aim of this study was to evaluate fear and anxiety related to dental care in senegaleese pediatric children living in Dakar. We have used the children's Fear survey Schedule Dental Sb scale (CFSS-DS) in 415 senegalese children of both sex with a age anking from 7 to 15 years. The results showed a mean score of 33.222 +/- 11.162. Girls revealed a significant higher score (35.122 +/- 11.692) than boys (29.168 +/- 9.704) (p < 0.05). These mean score increase with age in both boys than girl. In addition, more than 43.5% of the children have never consulted a dentist previously and 28% among them showed fear of the dentist. 17% of the children who have dental experiences showed fear of the dentist. This study has showed that senegalease children revealed fear of the dental care even those who have never been to a dentist. It also point out the problem of the origine of dental fear in children.
