RESUMO

INTRODUCTION: In Senegal, marital infertility is a real problem for society. We undertook the study of this subject to make an analysis of the spermatic parameters of the infertile Senegalese man and to better understand the impact of testicular morphological anomalies on male fertility. PATIENTS AND METHODS: We conducted a cross-sectional, descriptive, retrospective study of 100 infertile patients followed at the Histology-Embryology-Cytogenetics laboratory of UCAD in Dakar, during the year 2020. Sperm parameters, presence of varicocele, and testicular volume were evaluated in our patients. RESULTS/DISCUSSION: The mean age of the patients was 35.17±8.7 years. A history of sexually transmitted infections was found in 57% of patients. The mean duration of infertility was 5.67±3.2 years. The mean sperm count was 14,871,230/ml±4,950,000. Necrospermia was the most frequent abnormality found (60%), followed by asthenospermia (51%). The high rate of necrospermia could be explained by the high frequency of sexually transmitted infections. Other abnormalities were oligospermia (48%, including 09% cryptospermia), azoospermia (19%), teratospermia (19%), and hypospermia (13%). The predominance of azoospermia and oligospermia should prompt a search for a genetic predisposition in these subjects. The mean testicular volume was 10.3±4.9 cc on the right and 9.5±4.8 cc on the left. A single or bilateral varicocele was found in 43% of subjects. Patients with azoospermia and teratospermia were associated with testicular hypotrophy with a significant value (p=0.04). CONCLUSION: Overall, the senegalese man consulting for infertility is a young adult, married for an average of 5 years. Necrospermia is the most frequently found anomaly. The severity of both qualitative and quantitative abnormalities should lead to a systematic search for a genetic origin. The etiological research of infertile patients must be done within a multidisciplinary framework to propose better management of these patients.

RESUMO

BACKGROUND: In Senegal, psychological violence remains a taboo subject insofar as it often arises in the closed circle of family life. It has a highly negative impact on the health of pregnant women. The objective of this work was to study the epidemiological profile of female victims of psychological violence before and after birth in the Sédhiou region. METHOD: An observational, cross-sectional and analytical study was carried out from December 4, 2018 to April 4, 2019. The study population consisted of all the women received for postnatal consultation in one of the referral health structures in the Sédhiou region. Data were collected using a survey form and a questionnaire administered to the women having met the inclusion criteria. The data were entered using CS Pro software and subsequently analyzed using R 3.4.4 software. RESULTS: The mean age of the women was 25.4±7.8 (14-43 years). A total of 222 women (55.5 %) had suffered psychological violence during the prepartum period. Isolated psychological violence represented 44.3 % of the surveyed population, while psychological violence associated with sexual or physical violence represented 8.0 % and 5.4 % of the respondent population, respectively. The factors associated with psychological violence during the prepartum period were pursuit of a professional activity [ORaj=4.7 (1.3-17.0)], high educational status [ORaj=7.0 (4.2-11.5)] and performance of fewer than 3 antenatal consultations (ANC) [ORaj=2.2 (1.2-4.0)]. Maternal, fetal and neonatal complications were more frequent among victims of psychological violence (P<0.05). During the postpartum period, 26.5 % of the women who had been victims of violence during the prepartum period mentioned the fact that the aggression had ceased. The other women continued to endure violence, which was even more intense among 2.5 %. CONCLUSION: Psychological violence among pregnant women has a negative impact on the health of the mother and the newborn. This state of affairs should induce health care providers to increase popular awareness of its detrimental effects. Communication efforts aimed at behavioral change will need to be combined during prenatal consultations with strengthened screening for violence, the objective being to achieve improved care.

RESUMO

The current study assesses the characteristics and outcomes of multiple myeloma (MM) patients, treated with novel agents for hematogenous extramedullary (HEMM) relapse. Consecutive patients diagnosed with HEMM between 2010-2018 were included. Patients' characteristics at diagnosis and at HEMM presentation, response to treatment, survival and factors predicting survival were recorded and analyzed. A group of 127 patients, all diagnosed with HEMM by imaging (87.3%) and/or biopsy (79%), were included. Of those, 44% were initially diagnosed with ISS3, 57% presented with plasmacytomas, and 30% had high-risk cytogenetics. Median time to HEMM was 32 months. In multivariate analysis, ISS3 and bone plasmacytoma predicted shorter time to HEMM (P = .005 and P = .008, respectively). Upfront autograft was associated with longer time to HEMM (P = .002). At HEMM, 32% of patients had no BM plasmacytosis, 20% had non-secretory disease and 43% had light-chain disease. Multiple HEMM sites were reported in 52% of patients, mostly involving soft tissue, skin (29%), and pleura/lung (25%). First treatment for HEMM included proteasome inhibitors (50%), immunomodulatory drugs (IMiDs) (39%), monoclonal antibodies (10%), and chemotherapy (53%). Overall response rate (ORR) was 57%. IMiDs were associated with higher ORR (HR 2.2, 95% CI 1.02-4.7, P = .04). Median survival from HEMM was 6 months (CI 95% 4.8-7.2). Failure to achieve ≥VGPR was the only significant factor for worse OS in multivariate analyses (HR = 9.87, CI 95% 2.35 - 39, P = .001). In conclusion, HEMM occurs within 3 years of initial myeloma diagnosis and is associated with dismal outcome. The IMiDs might provide a higher response rate, and achievement of ≥VGPR predicts longer survival.

RESUMO

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.

RESUMO

OBJECTIVE: To determine the risk of recurrent trophoblastic disease after normalisation of human chorionic gonadotrophin (hCG) levels in women with hydatidiform mole. DESIGN: A retrospective review of data from a national gestational trophoblastic disease centre. SETTING: The Trophoblastic Disease Unit, Dakar, Senegal. SAMPLE: Women with pregnancies affected by hydatidiform mole registered between 2006 and 2012. METHODS: The women were followed up in accordance with the hospital protocol 'Score de Dakar'. For women who progressed to gestational trophoblastic neoplasia (GTN) the time to onset of GTN, treatment and evolution were evaluated. The rate of evolution to GTN after normalisation of hCG was determined. MAIN OUTCOME MEASURES: Rate of occurrence of GTN after chemotherapy for hydatidiform mole. RESULTS: Five hundred and thirty-one women were diagnosed to have molar pregnancies. According to the hospital's protocol, 107 (20.2%) of these had chemotherapy and 224 (42.2%) had prophylactic chemotherapy. Five hundred and thirteen women (96.4%; 95% confidence interval [95% CI] 95.05-98.14%) achieved remission. Eighteen women (3.4%; 95% CI 1.86-4.94%) developed GTN (11 before remission and seven after remission). Seven women out of the 18 developed GTN after hCG normalisation (1.3%). Five of these seven were diagnosed beyond the recommended period of follow up. The mean interval to diagnosis of GTN was 18.7 months. These seven women underwent combination chemotherapy: five achieved complete remission whereas two died from GTN. CONCLUSIONS: Cytotoxic therapy for hydatidiform mole does not prevent GTN, it delays its diagnosis and promotes GTN after normalisation of hCG.

RESUMO

BACKGROUND: Despite the frequency of hysterectomy, several studies have reported physical and psychological sequelae of this intervention. BUT: To evaluate the consequences of hysterectomy, their level of importance and how patients experience hysterectomy. METHODS: That is a prospective study of 70 patients who underwent a hysterectomy from January 2009 to June 2011 at Pikine National Hospital. The experience of hysterectomy was determined by the physical and psychosocial felt after surgery. RESULTS: Hysterectomy represented 5.9 % of gynecological surgical activities. The indications were dominated by myoma (57.1%). Hysterectomy was performed abdominally in 78.6% of cases and associated with bilateral salpingo-oophorectomy in 87% of cases. After surgery, new symptoms appeared: hot flushes, night sweats, urinary incontinence and urge incontinence in respectively 65.7%, 54.3%, 7.1% and 11.4% of patients. A proportion of 45.6% of them had resumed sexual activity after 90 days. The fear of pain at the time of intercourse was expressed in 55.7% of cases. A decrease in the frequency of sexual intercourse was found in 54.3% of patients. A drop of pleasure during sex was expressed in 38.6% of patients. Psychological effects were also reported by patients: decreased confidence in 31.4% of patients, feeling of being rejected by her husband in 5.7% of cases, sensation of mutilation in 24.3% of cases. CONCLUSION: Physical and psychological postoperative impacts of hysterectomy are real. Adequate accompanying measures are necessary, in addition to preoperative preparation, to allow patients to improve the experience of hysterectomy.

RESUMO

INTRODUCTION: Prosthetic teeth size and placement must be in perfect harmony with the bucco-facial structures for a successful and esthetic removable prosthesis. This study aimed to determine among young Senegalese black people facial index estimating maxillary central incisor width and distance between canine points starting from bizygomatic width. PATIENTS AND METHODS: 621 black Senegalese participated to this transversal study. Measurements were made using anthropometric slide caliper and electronic slide caliper. The comparative analysis was carried out by the test t of Student. The correlative analysis used the chi-square test. The risk of error was fixed at 5%. RESULTS: Positive correlations were found between variables. Distance between canine points was significantly (p = 0.000) correlated to bizygomatic width and central incisor width. Using bizygomatic width, the average dividing factors to estimate central incisor width and distance between canine points were respectively 15.13 and 3.75. CONCLUSION: Distance between canine points and central incisor width can be given starting from bizygomatic width, as guide of selecting maxillary anterior prosthetic teeth width.

RESUMO

Rehabilitation with complete denture include among other objectives, improvement of facial and dental esthetics. To these ends, the artificial teeth should mimic as far as possible, healthy and natural dentition. The main objective of this study was to investigate factors associated with tooth color among black African subjects. One hundred and two subjects (72 men and 30 women) were included in this investigation. The colorimetric parameters of their teeth as well as those of the conjunctiva of their eyes and skin were recorded from standardized photographs. Two software, Mesurim and Photoshop were used for that purpose. Univariate and linear regression analysis were run to assess the association between tooth color and the variables age, gender and colorimetric parameters of eyes and skin. It appears from the result of this study that tooth color was positively and significantly associated with age. Stepwise multiple regression analysis further revealed that tooth hue can be best predicted by a combination of skin complexion and brightness and eye lightness.

RESUMO

BACKGROUND: Maternal mortality is still too high in sub-Saharan Africa, particularly in referral hospitals. Solutions exist but their implementation is a great issue in the poor-resources settings. The objective of this study is to assess the effect of the organization of obstetric care services on maternal mortality in referral hospitals in Mali. METHODS: This is a multicentric observational survey in 22 referral hospitals. Clinical data on 42,929 women delivering in the 22 hospitals within the 2007 to 2008 study period were collected. Organization evaluation was based on explicit criteria defined by an expert committee. The effect of the organization on in-hospital mortality adjusted on individual and institutional characteristics was estimated using multi-level logistic regression models. RESULTS: The results show that an optimal organization of obstetric care services based on eight explicit criteria reduced in-hospital maternal mortality by 41% compared with women delivering in a referral hospital with sub-optimal organization defined as non-compliance with at least one of the eight criteria (ORa=0.59; 95% CI=0.34-0.92). Furthermore, local policies that improved financial access to emergency obstetric care had a significant impact on maternal outcome. CONCLUSION: Criteria for optimal organization include the management of labor and childbirth by qualified personnel, an organization of human resources that allows timely management of obstetric emergencies, routine use of partography for all patients and availability of guidelines for the management of complications. These conditions could be easily implemented in the context of Mali to reduce in-hospital maternal mortality.

RESUMO

BACKGROUND: In sub-Saharan Africa, problems of access to relevant and high-quality facility-based statistics hinder the assessment of safe motherhood programs. The objective of this study was to assess the quality of data collected in referral hospitals in Mali and Senegal after the routine information system (RIS) was strengthened. METHODS: This was a multicenter observational study conducted during the pre-intervention period of a randomized controlled trial (trial QUARITE). The RIS was strengthened based on technical, organizational and behavioral factors. We included all women who gave birth in the 46 referral hospitals from October 1, 2007 to October 30, 2008. The completeness, completion and accuracy rates were monitored every 3 months in each hospital. The cost of investment needed to strengthen the existing RIS was also determined. RESULTS: The mean completeness rate ranged from 94 to 97% depending on the study period. The completion and accuracy rates increased during the study period from 72% and 79% to 87% and 93%, respectively (significant differences). The average investment per hospital was less than 1% of state subsidies for public hospitals. CONCLUSION: Strengthening the existing information system has set up an economically and technologically appropriate system for monitoring maternal and perinatal health in Senegal and Mali. We encourage policy makers and researchers from countries with limited resources to invest in RIS to improve and monitor the performance of health systems.

RESUMO

INTRODUCTION: Urachus is an embryonic remnant that usually involutes before birth. Abnormal persistence of this structure gives embryologic malformation like an urachal cyst. Infection or malignancy degeneration can complicated it. CASE PRESENTATION: Case 1: We report 20 years old female patient consulted with acute abdominal pain. Clinical examination showed fever and infra-umbilical tender mass. The abdominal Computerized Tomography showed pelvic mass between umbilicus and bladder. The open laparotomy found infra-abdominal semi-solid mass. A complete resection was done and histological exam confirmed infected urachal cyst. Case 2: A 19 years old male patient presented with abdominal pain and fever. Physical examination found tenderness in lower abdomen. Biology revealed leukocytosis, and Ultrasonography found a heterogeneous infra-umbilical mass. Surgical exploration by mini-laparotomy found an abscess urachal cyst that is confirm by histological exam after complete resection. CLINICAL DISCUSSION: Urachal cyst in adult patient is rare. Clinical symptoms without complications are insignificant. Because of malignancy risk, adult urachal cyst are managed by surgery. CONCLUSION: Infection cyst is the most common complication of urachal cyst. Complete resection is recommended because of malignancy degeneration risk.

RESUMO

Materials in nature have fascinating properties that serve as a continuous source of inspiration for materials scientists. Accordingly, bio-mimetic and bio-inspired approaches have yielded remarkable structural and functional materials for a plethora of applications. Despite these advances, many properties of natural materials remain challenging or yet impossible to incorporate into synthetic materials. Natural materials are produced by living cells, which sense and process environmental cues and conditions by means of signaling and genetic programs, thereby controlling the biosynthesis, remodeling, functionalization, or degradation of the natural material. In this context, synthetic biology offers unique opportunities in materials sciences by providing direct access to the rational engineering of how a cell senses and processes environmental information and translates them into the properties and functions of materials. Here, we identify and review two main directions by which synthetic biology can be harnessed to provide new impulses for the biologization of the materials sciences: first, the engineering of cells to produce precursors for the subsequent synthesis of materials. This includes materials that are otherwise produced from petrochemical resources, but also materials where the bio-produced substances contribute unique properties and functions not existing in traditional materials. Second, engineered living materials that are formed or assembled by cells or in which cells contribute specific functions while remaining an integral part of the living composite material. We finally provide a perspective of future scientific directions of this promising area of research and discuss science policy that would be required to support research and development in this field.

RESUMO

INTRODUCTION: Childhood type 1 diabetes (T1D) is a chronic condition with serious repercussions on both the quality of life of the child and the family. Insulin therapy is the cornerstone of optimal blood sugar control. The main objective of our study was to assess the level of knowledge of physicians about insulin therapy in diabetes. METHODS: This was a multicenter survey over a period of 5 months (from March 5 to August 2, 2018). It took place in five reference university hospital centers in the Dakar region. RESULT: The number of doctors interviewed in our study was 82, 47.6% of whom were confirmed pediatricians or pediatricians in the process of specialization. The number of years of experience in the field of diabetes was on average 3 years. Fast-acting regular insulins were recommended by 75.6% of doctors and mixtures of insulin (intermediate and rapid-acting) by 50% of doctors. Overall, 91% of doctors recommend a variation in insulin injection sites. The "basal bolus" treatment regimen with insulin analogs was recommended by 50% of doctors, while 31.7% recommended it with human insulin. Regarding adapting insulin doses for leisure and sports activities, more than half (54.9%) of the doctors had to reduce the doses. CONCLUSION: This study enabled us to assess the level of knowledge of insulin therapy among doctors caring for children with diabetes in Senegal, which proved to be limited. We recommend the reinforcement and follow-up of training on the management of T1D for providers at the different facilities.

RESUMO

More than 35% of lung adenocarcinoma patients have bone metastases at diagnosis and have a poor survival. Periostin, a carboxylated matrix protein, mediates lung cancer cell dissemination by promoting epithelial-mesenchymal transition, and is involved in bone response to mechanical stress and bone formation regulation. This suggests that periostin may be used as a biomarker to predict survival in lung cancer patients. Serum periostin was assessed at diagnosis in a prospective cohort of 133 patients with lung adenocarcinoma of all stages. Patients were divided into localized and bone metastatic groups. Both groups were matched to healthy controls. Survival analysis and Cox proportional hazards models were conducted in the total population and in bone metastatic group. The median serum periostin level was higher in bone metastatic (n = 67; median: 1752 pmol/L) than in the localized group (n = 66; 861 pmol/L; p < 0.0001). Patients with high periostin (>median) had a poorer overall survival in the whole population (33.3 weeks vs. NR; p < 0.0001) and the bone metastatic group (24.4 vs. 66.1 weeks; p < 0.001). In multivariate analysis, patients with high periostin had increased risk of death (HR = 2.09, 95%CI [1.06-4.13]; p = 0.03). This was also found in the bone metastatic group (HR = 3.62, 95%CI [1.74-7.52]; p = 0.0005). Immunohistochemistry on bone metastasis biopsies showed periostin expression in the bone matrix and nuclear and cytoplasmic staining in cancer cells. Serum periostin was an independent survival biomarker in all-stage and in bone metastatic lung adenocarcinoma patients. IHC data suggest that periostin might be induced in cancer cells in bone metastatic niche in addition to bone microenvironment expression.

RESUMO

The skin epidermis is continuously exposed to external aggressions, including environmental pollution. The cosmetic industry must be able to offer dedicated products to fight the effects of pollutants on the skin. We set up an experimental model that exposed skin explants maintained in culture to a pollutant mixture. This mixture P representing urban pollution was designed on the basis of the French organization 'Air Parif' database. A chamber, called Pollubox®, was built to allow a controlled nebulization of P on the cultured human skin explants. We investigated ultrastructural morphology by transmission electron microscopy of high pressure frozen skin explants. A global transcriptomic analysis indicated that the pollutant mixture was able to induce relevant xenobiotic and antioxidant responses. Modulated detoxifying genes were further investigated by laser micro-dissection coupled to qPCR, and immunochemistry. Both approaches showed that P exposure correlated with overexpression of detoxifying genes and provoked skin physiological alterations down to the stratum basale. The model developed herein might be an efficient tool to study the effects of pollutants on skin as well as a powerful testing method to evaluate the efficacy of cosmetic products against pollution.

RESUMO

In Senegal, patients are seen an average of 16 months after their injury in a specialized hand and upper limb surgery department. Because of this lengthy delay, these patients have severe functional sequelae, such as wrist flexion contracture, averaging 45 degrees in our case series (range, 35 to 90 degrees). After reviewing the literature, we did not find any splint that was well suited to these patients. Inspired by the general splinting rules set out by Schultz, MacConaill and Brand, we constructed a volar/dorsal splint to reduce these contractures. We have been using this serial static splint for 2 years. We performed a prospective study of 17 wrists to evaluate its therapeutic benefit, describe its use and outline its optimal application.

RESUMO

To describe the process of establishing a reference center for gestational trophoblastic diseases (GTD) in Senegal and to report its main results so far. We describe the history and establishment of the center, which is based on the experience of the main international centers. The adaptations made to patient follow-up are detailed, while we follow FIGO and WHO diagnostic and management criteria. Finally, we report our main results. Between 2011 and 2017, 878 files were registered at the Center. More than half of the women had no histological confirmation of GTD (60.8 %). The diagnosis was then based on ultrasound images or macroscopic examination of molar vesicles. Spontaneous remission occurred in 64.5 % of the cases, while gestational trophoblastic neoplasia developed in 23.5 %. The FIGO criteria were slightly adapted for hCG monitoring. Methotrexate was the drug of choice in the low-risk group (97.8 %), while the EMACO protocol was financially difficult for nearly half of the high-risk group. The overall remission rate was 83 % and the specific lethality 11.6 %. Our center has demonstrated the efficiency of centralizing the management of GTDs. Difficulty in access to hCG and antimitotic drugs makes management difficult. However, we have introduced alternative solutions that we are working to improve.

RESUMO

Nosocomial Infection (NI) is also observed in healthcare facilities in non-Western countries. The purpose of this report is to describe the findings of a survey undertaken to evaluate hygiene procedures implemented at the "Hopital Principal" in Dakar, Senegal and to assess perception and awareness of nosocomial risk among the hospital staff. A total of 264 healthcare workers were interviewed. Mean age was 39 years (range, 18-60) and the sex ratio was 1.3 (150 men/114 women). Sixty (22.7%) had university degrees, 106 (40.2%) had secondary school diplomas, 50 (18.9%) had attended middle school, and 13 (4.9%) had no schooling. Analysis of interview data showed that 56.1% (157/264) defined NI as infection acquired at the hospital but that only 9.8% (n=26) knew that a minimum 48-hour delay was necessary to distinguish nosocomial from community acquired infection. While understanding about NI was correlated with education level, data showed that 1 out of 3 physicians (13/39) failed to give the exact definition. Hand contact was cited as the second route of transmission. Isolation precautions were understood by 22.7% of personnel (60/264). Systematic handwashing was reported by 363% (96/264) but observation demonstrated that it was not performed properly regardless of the category of personnel. Care protocols were understood by 54.6% of persons interviewed (144/264). A hygiene-training course had been attended by 52.2% (n=138). Two thirds of the staff (69.7%: 54/264) was able to identify the hygiene nurse. Ninety-eight health care providers (37.1%) were familiar with the CLIN (Comités de Lutte contre les Infections Nosocomiales).

RESUMO

Intussusception is a rare cause of bowel obstruction in adults, and has generally an organic etiology. However, adenomatous polyp of the small bowel is an uncommon etiology. Moreover, there's a great difference with childhood intussusception in its presentation, etiology and management. We describe herein a case of adult ileocecal intussusception due to an adenomatous ileal polyp with a preoperative diagnosis made on computed tomography. We performed a right hemicolectomy, without attempting to reduce the intussusception, and an end-to-end ileotransverse anastomosis. The pathological examination of the surgical specimen revealed an adenomatous polyp with a high grade dysplasia on the terminal ileum, being the cause of the ileocecal intussusception.
