Abstract
OBJECTIVE To determine the periodontal factors associated with stroke in melanodermic subjects in Senegal. STUDY DESIGN Case-control study. METHODS One hundred and twenty cases and 120 controls were included in this study. Cases had been diagnosed with stroke by a neurologist, with the diagnosis confirmed by scanner. Controls had never had any type of stroke. Data were collected regarding sociodemographic characteristics, lifestyle behaviours, general history, type of stroke (ischaemic or haemorrhagic) and periodontal parameters [plaque index, papillary bleeding index, pocket depth, clinical attachment loss, Community Periodontal Index of Treatment Needs and periodontitis (defined by clinical attachment loss >2 mm and pocket depth >3 mm)]. Logistic regression analysis was performed using R software to isolate a final model after adjustment for the 5% threshold. RESULTS All periodontal characteristics were more common among cases than among controls. Periodontitis (odds ratio 1.58, 95% confidence interval 1.1-3.022) and periodontal parameters were significantly associated with stroke, adjusted for hypertension, sedentary lifestyle, and the interaction between periodontitis and age. CONCLUSIONS Periodontal disease is associated with stroke in the Senegalese population. Prospective longitudinal studies should be undertaken to improve understanding.

Abstract
A patient presented with intertrigo at the second, third and fourth interdigitals spaces lasting for four years in which Fusarium solani was highlighted. The search for contributing factors revealed a concept of foot washing with water at least five times a day for ablutions, associated with wearing closed shoes all day and the absence of immunosuppression and diabetes. The diagnosis of Fusarium was made on the basis of direct examination and culture. Combined treatment with griseofulvin oral and topical ciclopirox was introduced and allowed healing after 45 days at which an antifungal powder was prescribed for relay. This case adds to the rare cases of intertrigo Fusarium sp. and confirms the frequent practice of ablutions as favoring factor.

Abstract
OBJECTIVE The pathology of the salivary glands focuses on that of the parotid gland. The purpose of this study is to clarify and explain the epidemiological features of parotid tumors in a Senegalese context, to highlight the importance of clinical examination when access to complementary investigations is limited, to discuss respective indications and finally to describe certain aspects of treatment in our context. MATERIALS AND METHODS This retrospective study of 114 cases of parotidectomy spans 16 years, from 1992 to 2007. It was performed in the ENT department of University Hospital of Fann, Senegal. All patients operated on for chronic mass of the parotid region for whom histological results were available when initially included. Benign swellings were subsequently excluded. The study parameters were epidemiological, clinical, paraclinical and surgical. RESULTS The 114 parotidectomies showed a predominance of benign tumours: 63 procedures (55.26%) essentially concerned pleomorphic adenoma; 30 cases (26.31%) concerned malignant tumours, mainly parotid adenocarcinoma. There were 21 cases of benign swelling (18.4%). The study focused on the series of 93 cases of benign and malignant tumours of the parotid gland. Both sexes were affected similarly. All age groups were concerned, from 5 to 89 years. A total of 97% of patients underwent surgery: conservative total parotidectomy in 75.51% of cases. CONCLUSION Although there are features specific to the local context, the epidemiological profile of parotid tumours is well-known. Indications for complementary investigations are discussed, as availability in Senegal is restricted, highlighting the important role of clinical examination in the management of parotid tumours.

Genomic analysis of three African strains of Bacillus anthracis demonstrates that they are part of the clonal expansion of an exclusively pathogenic bacterium. New Microbes New Infect 2014; 2:161-9. [PMID: 25566394 PMCID: PMC4265047 DOI: 10.1002/nmi2.62] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2014] [Revised: 07/04/2014] [Accepted: 08/08/2014] [Indexed: 01/31/2023] Open
Abstract
Bacillus anthracis is the causative agent of anthrax and is classified as a
‘Category A’ biological weapon. Six complete genomes of
B. anthracis (A0248, Ames, Ames Ancestor, CDC684, H0491, and Sterne) are
currently available. In this report, we add three African strain genomes: Sen2Col2, Sen3 and Gmb1.
To study the pan-genome of B. anthracis, we used bioinformatics tools, such
as Cluster of Orthologous Groups, and performed phylogenetic analysis. We found that the three
African strains contained the pX01 and pX02 plasmids, the nonsense mutation in the
plcR gene and the four known prophages. These strains are most similar to the
CDC684 strain and belong to the A cluster. We estimated that the
B. anthracis pan-genome has 2893 core genes (99% of the genome size)
and 85 accessory genes. We validated the hypothesis that B. anthracis has a
closed pan-genome and found that the three African strains carry the two plasmids associated with
bacterial virulence. The pan-genome nature of B. anthracis confirms its lack
of exchange (similar to Clostridium tetani) and supports its exclusively pathogenic
role, despite its survival in the environment. Moreover, thanks to the study of the core content
single nucleotide polymorphisms, we can see that our three African strains diverged very recently
from the other B. anthracis strains.

Abstract
Malarial infection in non immune pregnant women is a major risk factor for pregnancy failure. However in malaria endemic areas, intermittent preventive treatment (IPTp) have been adopted to prevent malaria in pregnancy women since 2003 in Senegal. The impact of IPT on the development of immunity is not very well documented. We conducted a prospective study at the Roi-Baudouin maternity hospital of Guediawaye in Senegal to assess IL10, IL12, TNFα and IFNγ cytokines production in pregnant women under IPTp. Cytokines were analyzed in 82 sera at inclusion and delivery. P. falciparum HRP2 antigen was detected in 17% of women included by rapid diagnostic test (RDT). At inclusion the mean of IL10 response was higher in P. falciparum negative women (8 UA) compare to RDT-positive women (7 UA) p=0.069 while in delivery the opposite was found p=0.014. Low production of inflammatory cytokines IL12, IFNγ and TNFα was noted in both groups. Between inclusion and delivery, a significant increase of IL-10 production was noted while a decrease of IFNγ and TNFα cytokine was noted. Thus, IL12 and IFNγ responses may synergistically associate as malaria immune response during pregnancy.

Abstract
Rapid diagnosis tests (RDTs) allow for the confirmation of malaria diagnosis. In Senegal, RDTs detecting HRP2 have been adopted in 2008 for malaria diagnosis. However, the sustainability of this strategy requires adequate and regular quality control. PCR on DNA extracted in nitrocellulose band of RDTs enable quality control. A RDT (Malaria Antigen P.f®) and a thick smear were performed on patients with suspected malaria. DNA was extracted from the nitrocellulose band of RDTs to which a non-specific PCR and a specific PCR were applied. The results of the RDT were compared with those obtained from the thick smear and the PCR to measure sensitivity, specificity as well as positive and negative predictive values. For 81.6% of the 273 patients involved, the thick smear was positive. Rapid diagnosis tests were positive for 85.7% of the patients. Non-specific PCR was positive on 87.9% of RDTs. Plasmodium falciparum was found in 99.5% of patients and Plasmodium ovale appeared in only 0.4% of patients. Sensitivity of the Malaria Antigen Pf® RDT in relation to thick smear and to PCR was 98.2% and 97.1% respectively. Quality control with PCR on the nitrocellulose band performed several months after it was used confirms its adequate level of sensitivity. The collection and screening of DNA present in already used RDT is a good means of quality control for this tool. It is also a relevant alternative to the molecular approach in the context of a reduction in the transmission of malaria.

Abstract
BACKGROUND The genetic diversity of Plasmodium falciparum has been extensively studied in various parts of the world. However, limited data are available from Mauritania. The present study examined and compared the genetic diversity of P. falciparum isolates in Mauritania. METHODS Plasmodium falciparum isolates blood samples were collected from 113 patients attending health facilities in Nouakchott and Hodh El Gharbi regions. K1, Mad20 and RO33 allelic family of msp-1 gene were determined by nested PCR amplification. RESULTS K1 family was the predominant allelic type carried alone or in association with Ro33 and Mad20 types (90%; 102/113). Out of the 113 P. falciparum samples, 93(82.3%) harboured more than one parasite genotype. The overall multiplicity of infection was 3.2 genotypes per infection. There was no significant correlation between multiplicity of infection and age of patients. A significant increase of multiplicity of infection was correlated with parasite densities. CONCLUSIONS The polymorphism of P. falciparum populations from Mauritania was high. Infection with multiple P. falciparum clones was observed, as well as a high multiplicity of infection reflecting both the high endemicity level and malaria transmission in Mauritania.

Abstract
BACKGROUND Community case management of malaria (CCMm) and seasonal malaria chemoprevention (SMC) are anti-malarial interventions that can lead to substantial reduction in malaria burden acting in synergy. However, little is known about the social acceptability of these interventions. A study was undertaken to assess whether combining the interventions would be an acceptable approach to malaria control for community health workers (CHWs). METHODS Sixty-one interviews and six focus group discussions were conducted nested in a cluster-randomized trial assessing the impact of combining CCMm and SMC in a rural area of Senegal. Participants consisted of: (i) members of village associations, (ii) members of families who had access to the interventions as well as members of families who did not access the interventions, (iii) CHWs, and (iv) community leaders, e g, religious guides and village chiefs. RESULTS The interventions were acceptable to the local population and perceived as good strategy to make health care services available to community members and thus, to reduce the delays in access to anti-malarial treatment as well as expenses related to patients' transfer to the health post. The use of malaria rapid diagnostic test (RDT) contributed to improving CHWs diagnostic capacity as well as malaria treatment practices. Study participants notified RDT and drugs stock-out as the major risk for sustainability of the intervention at community level. CONCLUSION Combining CCMm and SMC is a well accepted, community-based approach that can contribute to control malaria in areas where malaria transmission is seasonal.

Abstract
Although malaria is declining in many countries in Africa, malaria and anaemia remain frequent in children. This study was conducted to assess the relationship between malaria parasitaemia, intestinal worms, and anaemia, in children <5 years living in low transmission area in Senegal. A survey was carried out in 30 villages in the central part of Senegal. A two-level random cluster sampling technique was used to select study participant. Children <5 years were enrolled after informed consent. For each child, blood thick and smear tests were performed, haemoglobin concentration was measured with HemoCue, and stool samples were collected and examined using the Ritchie technique. A total of 736 children were recruited. Malaria parasite prevalence was 1.5% (0.7-2.6); anaemia was found in 53.4% (48.2-58.9), while intestinal parasites and stunting represented 26.2% (22.6-30.2) and 22% (18.6-25.5), respectively. In a logistic regression analysis, anaemia was significantly associated with malaria parasitaemia (aOR= 6.3 (1.5-53.5)) and stunting (aOR = 2 (1.2-3.1)); no association was found between intestinal parasites and anaemia. Malaria and anaemia remain closely associated even when malaria is declining. Scaling up antimalarial interventions may contribute to eliminate malaria and reduce the occurrence of anaemia among children.

Abstract
Background Malaria remains a major public health problem in developing countries. Then in these countries prompt access to effective antimalarial treatment such as Artemisinin based-Combination Therapies (ACT) proves to be an essential tool for controlling the disease. In Senegal, since 2006 a nationwide scaling up program of ACT is being implemented. In this context it has become relevant to monitor ACT efficacy and provide recommendations for the Senegalese national malaria control program. Methods An open randomized trial was conducted during two malaria transmission seasons (2011 and 2012) to assess the efficacy and safety of three combinations: dihydro-artemisinin-piperaquine (DHAPQ), artemether-lumefantrine (AL) and artesunate-amodiaquine (ASAQ). The primary end point of the study was represented by a PCR adjusted adequate clinical and parasitological response (ACPR) at day 28. Secondary end points included: (i) a ACPR at days 35 and 42, (ii) a parasite and fever clearance time, (iii) ACTs safety and tolerability. The 2003 WHO’s protocol for antimalarial drug evaluation was used to assess each outcome. Results Overall, 534 patients were randomized selected to receive, either ASAQ (n = 180), AL (n = 178) or DHAPQ (n = 176). The PCR adjusted ACPR at day 28 was 99.41% for the group ASAQ, while that was 100% in the AL and DHAPQ groups (p = 0.37). The therapeutic efficacy was evaluated at 99.37% in the ASAQ arm versus 100% in AL and DHAPQ arm at day 35 (p = 0.37). At day 42, the ACPR was 99.27% in the ASAQ group versus 100% for both AL and DHAPQ groups, (p = 0.36). No serious adverse event was noted during the study period. Also a similar safety profile was noted in the 3 study groups. Conclusion In the context of scaling up of ACTs in Senegal, ASAQ, AL and DHAPQ are highly effective and safe antimalarial drugs. However, it’s remains important to continue to monitor their efficacy. Trial registration PACTR 201305000552290.

Abstract
BACKGROUND Home-based management of malaria (HMM) may improve access to diagnostic testing and treatment with artemisinin combination therapy (ACT). In the Sahel region, seasonal malaria chemoprevention (SMC) is now recommended for the prevention of malaria in children. It is likely that combinations of antimalarial interventions can reduce the malaria burden. This study assessed the feasibility, effectiveness and safety of combining SMC and HMM delivered by community health workers (CHWs). METHODS A cluster-randomised trial was carried out during two transmission seasons in eight villages located in the south-eastern part of Senegal. Intervention communities received HMM+SMC while control communities received HMM. Primary end point was the incidence of malaria attacks during the follow up period. Secondary end points included: malaria diagnostic accuracy; access to ACT treatment; SMC coverage; safety and drug tolerability. RESULTS The adjusted rate ratio for incidence of malaria attacks in intervention and control communities was 0.15, indicating a protective effect of HMM+SMC of 85% (95% CI: 39.9-96.3%, p=0.01). Access to ACT treatment was 96.4% while SMC coverage represented 97.3% (95% CI: 91.3-100%) in 2010, and 88.8% (95% CI: 84.2-93.6%) in 2011. No serious adverse events were recorded. CONCLUSION It seems feasible and safe to combine SMC with HMM intervention, while achieving high coverage and effectiveness of both SMC and HMM.

Abstract
OBJECTIVES To analyze the epidemiology, diagnosis, management and the prognosis of cholesteatoma of the middle ear in children. METHODS This was a retrospective study of 15 years (from 01 January 1995 to 31 December 2009) for patients aged 0-15 years admitted in ENT ward of FANN hospital for chronic otitis media complicated with cholesteatoma The parameters studied were epidemiology, clinical presentation, disease progression and management. RESULTS Sixty-six participants were included. We noted a slight male predominance with a sex ratio of 1.44. The average mean age was 10 years. Most patients presented with signs of complications (69.7%) and mastoiditis was the most common complication (63.6%). The otorrhea was noted in almost all patients: n = 64 (97%) and deafness in 49 patients (74, 2%). There was a slight predominance of cholesteatoma on the right side (51.5%). Schuller's view of the mastoid cells was done in 21.2% of patients (n = 14) and showed sclerotic mastoid air cells for all them. Eighty-two percent (82%) of patients presented with conductive hearing loss. A radical mastoidectomy was performed in 66.7% and modified radical mastoidectomy in 33.3% of cases. Mean follow-up was 6 months. Recurrence of cholesteatoma was noted in 13% of cases. CONCLUSIONS ENT ward of Hospital Fann is one of the two centers in Senegal where cholesteatoma of the middle ear are treated. This low number of cholesteatoma in children in a developing country is in relation to the fact that patients only present when complications develop: 70% of cases. The reason for this in our setting include insufficient human and manpower resources necessary for prompt management of the disease and also lack of awareness among the populace. In these settings we advocate canal wall down mastoidectomy (radical or modified radical) as the treatment of choice.

Abstract
Primitive neuroectodermal tumors are a rare type of malignant neuroectodermal tumor that is very aggressive. Cervicofacial location is rare, even exceptional. We report a case of a 4-month-old male infant, referred from the pediatric clinic for severe supralaryngeal dyspnea, a firm mass under the left mandibular angle, mobile and extended to the parotid area, painful, with a curve of the left side wall of the oropharynx. Cervical computed tomodensitometry showed a well-limited mass in the carotid area, enhanced by the contrast product. A vascularized mass, which had developed at the expense of the vagus nerve, was removed surgically. Histology found a primitive neuroectodermal tumor.

Abstract
INTRODUCTION There are growing concerns about the emergence of resistance to artemisinin-based combination therapies (ACTs). Since the widespread adoption of ACTs, there has been a decrease in the systematic surveillance of antimalarial drug resistance in many malaria-endemic countries. The aim of this work was to test whether data on travellers returning from Africa with malaria could serve as an additional surveillance system of local information sources for the emergence of drug resistance in endemic-countries. METHODOLOGY Data were collected from travellers with symptomatic Plasmodium falciparum malaria returning from Senegal (n = 1,993), Mali (n = 2,372), Cote d'Ivoire (n = 4,778) or Cameroon (n = 3,272) and recorded in the French Malaria Reference Centre during the period 1996-2011. Temporal trends of the proportion of parasite isolates that carried the mutant genotype, pfcrt 76T, a marker of resistance to chloroquine (CQ) and pfdhfr 108N, a marker of resistance to pyrimethamine, were compared for travellers and within-country surveys that were identified through a literature review in PubMed. The in vitro response to CQ was also compared between these two groups for parasites from Senegal. RESULTS The trends in the proportion of parasites that carried pfcrt 76T, and pfdhfr 108N, were compared for parasites from travellers and patients within-country using the slopes of the curves over time; no significant differences in the trends were found for any of the 4 countries. These results were supported by in vitro analysis of parasites from the field in Senegal and travellers returning to France, where the trends were also not significantly different. CONCLUSION The results have not shown different trends in resistance between parasites derived from travellers or from parasites within-country. This work highlights the value of an international database of drug responses in travellers as an additional tool to assess the emergence of drug resistance in endemic areas where information is limited.
