EPILEPTIC SEIZURES REVEALING STURGE WEBER'S DISEASE IN A TROPICAL ENVIRONMENT: STUDY OF EIGHT CASES.

In sub-Saharan Africa (SSA), the etiological factors of epilepsy are multiple and phacomatoses, in particular Sturge weber's disease, are rarely reported due to under-medicalization and insufficient multidisciplinary care. We carried out a retrospective study of 216 patients hospitalized for recurrent epileptic seizures between 2015 and 2022 in the neurology and pediatrics department of the University Hospital Center of Conakry, among whom eight (8) patients were identified for Sturge Weber's disease in order to reassess this pathology from a clinical and paraclinical point of view in a tropical environment. Sturge Weber's disease was retained in eight (8) on the presence of symptomatic partial epileptic seizures (age 6 months to 14 years) with frequency of status epilepticus, homonymous lateral hemiparesis linked to occipital involvement, piriform calcifications on imaging and ocular disorders. The delay in consultation and medical care revealed severe mental deterioration in our patients. This study shows a stereotyped clinical picture in a context of aggravation of signs related to a delay in multidisciplinary management. These results are important for the diagnostic, therapeutic and prognostic discussion.

Development and evaluation of the perceived variety-support in physical education scale (PVSPES).

The provision of variety has been posited to influence motivation in physical education. Therefore, the aim of this 3-phase study was to design and evaluate a brief scale to assess ratings of variety-support in physical education. In Phase 1, 20 experts were invited to review the developed items of the Perceived Variety-Support in Physical Education (PVSPE) scale. In Phase 2, factorial validity of item responses was assessed in a sample of adolescents aged 12-14 years (n = 265). In Phase 3, test-retest reliability was determined over a one-week period (n = 100). A one-factor model resulted in "good" fit to the data (χ2(21) = 43.265, p < 0.001, CFI = 0.968, TLI = 0.952, RMSEA = 0.089; factor loading estimates showed that indicators were highly related to the factor (range: 0.60 to 0.93); and ICC was 0.98, 95% CI [0.97 to 0.98]. Our results provide initial evidence for the validity, measurement invariance, and test-retest reliability of scores derived from the VSPE scale for use with adolescents.

The Role of Visceral Obesity, Sarcopenia and Sarcopenic Obesity on Surgical Outcomes After Liver Resections for Colorectal Metastases.

BACKGROUND: The impact of body compositions on surgical results is controversially discussed. This study examined whether visceral obesity, sarcopenia or sarcopenic obesity influence the outcome after hepatic resections of synchronous colorectal liver metastases. METHODS: Ninety-four consecutive patients with primary hepatic resections of synchronous colorectal metastases were identified from a single center database between January 2013 and August 2018. Patient characteristics and 30-day morbidity were retrospectively analyzed. Body fat and skeletal muscle were calculated by planimetry from single-slice CT images at the level of L3. RESULTS: Fifty-nine patients (62.8%) underwent minor hepatectomies, and 35 patients underwent major resections (37.2%). Postoperative complications occurred in 60 patients (62.8%) including 35 patients with major complications (Clavien-Dindo grade III-V). The mortality was nil at 30 days and 2.1% at 90 days. The body mass index showed no influence on postoperative outcomes (p = 1.0). Visceral obesity was found in 66 patients (70.2%) and was significantly associated with overall and major complication rates (p = .002, p = .012, respectively). Sarcopenia was observed in 34 patients (36.2%) without a significant impact on morbidity (p = .461), however, with longer hospital stay. Sarcopenic obesity was found in 18 patients (19.1%) and was significantly associated with postoperative complications (p = .014). Visceral obesity, sarcopenia and sarcopenic obesity were all identified as significant risk factors for overall postoperative complications. CONCLUSION: Visceral obesity, sarcopenic obesity and sarcopenia are independent risk factors for overall complications after resections of CRLM. Early recognition of extremes in body compositions could prompt to perioperative interventions and thus improve postoperative outcomes.

[Treatment outcome, survival and their risk factors among new tuberculosis patients co-infected with HIV during the Ebola outbreak in Conakry]. / L'issue du traitement, la survie et ses facteurs de risque chez les nouveaux tuberculeux co-infectés par le VIH pendant l'épidémie d'Ebola à Conakry.

BACKGROUND: Mortality among TB/HIV co-infected patients remains high in Africa. The study aimed to estimate survival and associated factors in a cohort of TB/HIV co-infected patients who started tuberculosis treatment during the Ebola outbreak in Conakry, Guinea. METHODS: A prospective cohort study was conducted from April 2014 to December 2015. TB patients with HIV co-infection were enrolled at the University Hospital of Conakry. Survival and risk factors were analyzed according to Kaplan-Meier's method, log-rank test and Cox's regression. RESULTS: Data from 573 patients were analyzed. From these, 86 (15.0%) died before the end of treatment, 52% occurring within eight weeks of treatment onset. Survival at 4, 12 and 24 weeks after the beginning of the TB treatment was 92%, 86% and 83%, respectively. Independent risk factors associated with death were in the cell CD4 <200 cells/mm3 [adjusted hazard ratio (AHR): 2.25; 95% CI (confidence intervals): 1.16-4.37], opportunistic infections other than TB [AHR: 2.89; 95% CI: 1.39-6.02], and comorbidities [AHR: 4.12; 95% CI: 2.10-8.10]. An increase of one unit in hemoglobin [AHR: 0.81; 95% CI: 0.75-0.91] was protective of death. CONCLUSION: TB/HIV co-infected patients had a higher fatality rate during treatment of tuberculosis. Prevention of opportunistic infections, anemia and proper management of tuberculosis treatment in early comorbidities may improve survival for TB/HIV co-infected patients in restoring immune function.

[Obstetrical vesico-vaginal fistula in Guinea: Data analysis of three sites of treatment at Engender Health ONG]. / Fistules vésico-vaginales obstétricales en Guinée : analyse des données de 3 sites de prise en charge de l'ONG Engender Health.

OBJECTIVE: To analyze the management of obstetric vesico-vaginal fistula in the three sites of Engender Health in Guinea. PATIENTS AND METHODS: It was a retrospective study of descriptive type having helped collect 450 cases of vesico-vaginal fistulas in three support sites engender health between January 2008 and December 2011. The variables studied were epidemiological, clinical and therapeutic reasons and treatment outcomes were evaluated after a decline of at least six months. RESULTS: The mean age of onset of the fistula was 25years, ranging from 12 to 55years and 58.8% (n=265) of patients were aged between 18 and 30years. The mean duration of fistula was 11years, ranging from 1 to 38years. Eighty-two percent (n=416) of patients were housewives and 66.4% (n=299) off school. The complex fistula with 66% (n=297) was the most frequent. The treatment consisted of a fistulorraphie after splitting vesico-vaginal in 93.3% (n=420) of cases. Therapeutic results considered after a mean of 8months have resulted in a cure in 79.3% (n=357) of cases, improvement in 4.2% (n=19) of cases and failure in 16 4% (n=74) of cases. CONCLUSION: Vesico-vaginal fistula is a major cause of maternal morbidity in Guinea. The establishment of a real health policy based on sound medical and social structures contributes to its eradication. LEVEL OF EVIDENCE: 5.

Postoperative decrease in plasma sodium concentration after infusion of hypotonic intravenous solutions in neonatal surgery.

BACKGROUND: Hypotonic i.v. solutions can cause hyponatraemia in the context of paediatric surgery. However, this has not been demonstrated in neonatal surgery. The goal of this study was to define the relationship between infused perioperative free water and plasma sodium in neonates. METHODS: Newborns up to 7 days old undergoing abdominal or thoracic surgery were included in this prospective, observational study. Collected data included type and duration of surgery, calculated i.v. free water intake, and pre- and postoperative plasma sodium. Statistical analyses were performed using the Pearson correlation, Mann-Whitney test, and receiver operating characteristic analysis with a 1000 time bootstrap procedure. RESULTS: Thirty-four subjects were included. Postoperative hyponatraemia occurred in four subjects (11.9%). The difference between preoperative and postoperative plasma sodium measurements (ΔNaP) correlated with calculated free water intake during surgery (r=0.37, P=0.03), but not with preoperative free water intake. Calculated operative free water intake exceeding 6.5 ml kg(-1) h(-1) was associated with ΔNaP≥4 mM with a sensitivity and specificity [median (95% confidence interval)] of 0.7 (0.9-1) and 0.5 (0.3-0.7), respectively. CONCLUSIONS: Hypotonic solutions and i.v. free water intake of more than 6.5 ml kg(-1) h(-1) are associated with reductions in postoperative plasma sodium measurements ≥4 mM. In the context of neonatal surgery, close monitoring of plasma sodium is mandatory. Routine use of hypotonic i.v. solutions during neonatal surgery should be questioned as they are likely to reduce plasma sodium.

Ischemic strokes revealing neurosyphilis: Study of six (6) observations at the neurology Department of the University Hospital of Conakry.

Introduction: In sub-Saharan Africa (SSA), stroke is a major public health problem and the etiological aspects are poorly studied and documented because of under-medicalization; the syphilitic etiology is rarely mentioned. Patients and methods: We performed a retrospective study of 472 patients hospitalized for ischemic stroke between 2016 and 2021 in the Neurology Department of the University Hospital of Conakry, confirmed by neuroradiological explorations (brain CT, MRI-Angio) and a biological workup including VDRL-TPHA serological reactions in blood and CSF. Results: Syphilitic etiology was retained for six (6) patients (4 men and 2 women) with a mean age of 43 years (extremes 36 and 49 years). The clinical picture was dominated by carotid syndromes: superficial and deep sylvian syndrome, anterior cerebral artery syndrome and vertebro-basilar syndromes and one case of lacunar syndrome.The diagnosis was based on the positivity of serological reactions (VDRL-TPHA) in blood and cerebrospinal fluid (CSF) and the presence of a predominantly lymphocytic hypercellularity and a hyperproteinorachy in the CSF in the absence of any other etiology. Conclusion: These neurological vascular syndromes consecutive to a cerebral treponematous attack are often the result of a still poorly conducted management of primary and secondary syphilis in our country.

[The profile urological emergencies at the Conakry University Teaching Hospital, Guinea]. / Le profil des urgences urologiques au CHU de Conakry, Guinée.

OBJECTIVE: To stick out the profile urological emergencies at the Conakry University Teaching Hospital, Guinea. PATIENTS AND METHODS: This retrospective study, carried out over a period of 3 years (January 2005-December 2007), included 757 urological emergencies admitted to the urology department of the university hospital of Conakry, Guinea. RESULTS: The mean age of patients was 56 years. These patients had an age equal to or higher than 60 years in 58% of the cases. The sex ratio (M/F) was 16.6. According to the social profession, the farmer (40,6%) and workers (21%) were the dominant patients. The most frequent illness was vesical urinary retention (73.9%), hematuria (9.6%) and genito-urinary system trauma (7%). The most performed procedures were the installation of a urethral catheter (55.25%) and the installation of a suprapubic catheter (24.14%). CONCLUSION: The most frequent urological emergency in our country was vesical urinary retention, the hematuria and genito-urinary system trauma are not rare there.

Walking in PACU after unilateral spinal anesthesia a criteria for hospital discharge: a 100 outpatient survey.

PURPOSE: This study measured time and ability to walk in PACU after unilateral spinal anaesthesia. METHODS: Orthopaedic adult patients ASA 1-2, in the lateral decubitus position and placed on the operative side, received via a 25-gauge Whitacre needle 5 mg of 0.5% bupivacaine plus 2.5 microg of sufentanil. Lateral decubitus was maintained for 15 minutes. Time from the spinal injection to eligibility for discharge was recorded. Discharge criteria were stable hemodynamic and ability to walk without crutches. RESULTS: One hundred consecutive patients (38 females), 48 +/- 15 years-old were included. Unilateral sensory block was noted in 70% of patients. The maximum level of sensory block was at L1-T12 in 30 patients, at T11-T10 in 55 patients, at T9-T8 in 6 patients and at T7-T6 in 9. Criteria for PACU discharge were completed at 140 +/- 14 min (extremes: 55-235). All patients were discharged home uneventfully. CONCLUSION: Unilateral spinal anesthesia combining bupivacaine and sufentanil gives fast ability to walk for discharge.

[Prevalence of illegal abortions in Libreville Hospital, Gabon]. / Prévalence des avortements clandestins au centre hospitalier de Libreville, Gabon.

The objectives of this study were to determine the prevalence of illegal abortion in Libreville and to describe abortive methods used. It is a cross sectional and descriptive survey carried out at the maternity hospital of Libreville (MHL) during one year, from 1 January 2008 to 31 December 2008. 750 abortions were performed during this period and 651 cases were illegal abortions. Prevalence was of 86.7%. The women undergoing illegal abortion were most often pupils (67.1%), with an average age of 22.4 +/- 5.3 years old and a mean parity of 1.2 +/- 1.50. The average gestational term was of 7.4 +/- 1.9 weeks. Misoprostol (63.1%) was the most frequent abortive product used. 2 maternal deaths were notified. Prevalence of illegal abortions is increasing at the MHL. Up to now, misoprostol is the most frequent abortive product used.

[Dermatomyositis and pregnancy: a case in Gabon]. / Dermatomyosite et grossesse: une observation au Gabon.

The purpose of this report is to describe a case of successful pregnancy involving a 30-year-old Afican woman presenting dermatomyositis, without use of immunosuppressive treatment. The child was delivered prematurely by caesarean section at 32 weeks of gestation.

Prevalence, management and ethnobotanical investigation of hypertension in two Guinean urban districts.

ETHNOPHARMACOLOGICAL RELEVANCE: Hypertension is an important public health challenge in low- and middle-income countries, and in many African countries including Guinea medicinal plants are still widely used for its treatment. MATERIALS AND METHODS: The objective of this study was to determine the prevalence of hypertension in two Guinean urban districts (Pounthioun and Dowsare), to describe its management and to collect information on traditional herbal remedies. A total of 316 participants entered the study, 28.2% (89/316) men and 71.8% (227/316) women. Of these, 181 were from Dowsare (50 men and 131 women) and 135 from Pounthioun (39 men and 96 women). The mean age of subjects was 40.8 ±â€¯14.0 years (range18 - 88years), while the majority of subjects (63.3% or 200/316) were 45-74 years old. RESULTS: The overall prevalence of hypertension was 44.9% (142/316): 46.4% (84/181) from Dowsare and 43.0% (58/135) from Pounthioun. Ethnobotanical investigations among hypertensive patients led to the collection of 15 plant species, among which Hymenocardia acida leaves and Uapaca togoensis stem bark were the most cited. Phytochemical investigation of these two plant species led to the isolation and identification of isovitexin and isoorientin from H. acida, and betulinic acid and lupeol from U. togoensis. CONCLUSION: The presence of these constituents in Hymenocardia acida leaves and Uapaca togoensis stem bark may at least in part support their traditional use against hypertension in Guinea.

[Periodontal status in a sample of Senegalese women using hormonal contraception]. / Etat parodontal d'une population de femmes Sénégalaises sous contraception hormonale.

Hormonal contraception is based on the use of synthetic hormones containing variable doses of oestrogen and progesterone making it possible to avoid pregnancy in a temporary and reversible way. The objective of this study is to evaluate the periodontal status of a sample of Senegalese women under hormonal contraceptive. One hundred women using contraception since at least 6 month were paired on the age, the socio-economic profile and oral hygiene with a control group. Oral hygiene (plaque index (PI) of Silness and Löe), the inflammation (gingival index (GI) of Löe and Silness), probing depth and clinical attachment loss were recorded. With equal hygiene, the scores of the gingival index were significantly higher among women under contraceptive (p < 0.001). Inflammation was significantly more marked for the women who used contraception in injectable form compared to the control group (p < 0.001). Probing depth (3.01 +/- 0.04) and clinical attachment loss (3.19 +/- 0.08) were significantly more important among women under contraceptive (p < 0.001). The women under contraceptive seem to set up a group at risk for developing a periodontal disease, it is thus necessary to systematise periodontal appraisal before and during contraceptive use period.

Private pharmacy staff in five main towns in Benin, Burkina Faso, and Mali: knowledge and practices concerning malaria care in 2014.

The Global Fund's involvement in the fight against malaria has led to significant improvements, but mostly through programs supporting public-sector health facilities and personnel. The authors report the results of the preliminary survey preceding their intervention with private pharmacies. A simple random sampling technique was used to select the sample of pharmacies in urban areas in Burkina Faso, Benin, and Mali. A pretested questionnaire was administered to the supervisor present in each pharmacy at the time of the survey. Data were collected by local students in the first quarter of 2014. In all, 94 pharmacies were surveyed, representing 17.6% of all the pharmacies in these 5 cities. Among the participants, 84% knew about the national malaria control program, and 77.7% about artemisinin-based combination therapy (ACT), while 38.8% knew the national protocols. Licensed pharmacists had a better knowledge of ACT than their assistants, and training improved knowledge of treatment for uncomplicated malaria episodes. These pharmacists and assistants would like to be more involved in the fight against malaria. They are ready to advise ACT when appropriate after rapid detection tests. It is necessary to find resources for subsidized inputs in the private sector to make these drugs and tests more accessible for all patients.

Information about medications in the district of Bamako, Mali.

The aim of our study was to investigate the quality of information about pharmaceutical products in Mali. The study surveyed 98 prescribers, 60 pharmacists, and the package inserts of a basket of 30 generic medicines, compared to those of the corresponding proprietary versions. We made a rational choice of 98 doctors from various specialties and levels of the health system and randomly selected 60 of the 215 pharmacies in the district of Bamako (Mali). A rational sampling of generic medicines provided us with a basket of 30 drug notices for the antimalarial, antibiotic, antalgic, antipyretic, and anti-inflammatory agents used most in the Republic of Mali. This study showed that the pharmaceutical industry, through its sales representatives, are the main sources of drug information and that this information is not always adequate. The study also found that the content provided with generic medicines is sometimes different from the information for the proprietary brand-name drugs.

Automation for clinical CD4 T-cell enumeration, a desirable tool in the hands of skilled operators.

BACKGROUND: Automation in HIV clinical flow cytometry when appropriately applied brings considerable standardisation benefits. The Canadian Immunology Quality Assessment Program (CIQAP) detected situations where operators did not manually override automated software in the event of improper output on the Epics XL and FC500 CD4 immunophenotyping platforms. The automated gating algorithm identifies lymphocytes using a double gate strategy based on CD45 × side scatter (SS) gating and a light scatter FS × SS gate known to fail with sub optimal specimens. METHOD: To generate correct interpretation and results CIQAP introduced a simple protocol modification, bypassing the light scatter gate to include all cells characterized by the CD45 gate. Seventeen problem cases were reanalysed for both absolute and relative T-cell subsets accuracy and compared to the CIQAP group mean values. Results were found to be associated with the percentage of lymphocytes excluded by the automated light scatter gate. RESULTS: The modified manual protocol resolved poor performance in 14 instances out of 17 problem cases. It was found to improve accuracy when the light scatter gate excluded greater than 5% of the cells. The remaining three cases had a lymphocyte recovery of greater than 94.6% in the original automated analysis. CONCLUSION: There is a risk in relying solely on automated gating procedures when using the Epics XL and FC500 CD4 immunophenotyping platforms. Laboratory managers have the responsibility to intervene when required. EQA providers are equally responsible to alert the clinical laboratories of the need to update operator training to deal with stressed specimens. © 2016 International Clinical Cytometry Society.

[Seroprevalence of hepatitis C virus (HCV) in Senegalease blood donors]. / Seroprevalence du virus de l'hepatite C (VHC) chez les donneurs de sang au Senegal.

INTRODUCTION: Hepatitis C virus (HCV) is an important problem of public health in the world according to its transmission mode and its pathogenesis. The risk of blood transmission has led to be the systematic screening of blood donors in the world. In Senegal no study about HCV prevalence on the general population and also has been done. The aim of our study was to determine HCV prevalence in blood donors and the rate of co-infection with hepatitis B (HCV/HBV) or with HIV infection (HCV/HIV). MATERIALS AND METHODS: This study had been done in the National Blood Transfusion Centre (CNTS) in Dakar. Two different techniques has been used for the assessment HCV: 1/ ELISA technique and 2/ Immunoblot RIBA as confirmation test. RESULTS: Our study relates to 1565 blood donors recruited in CNTS during 2002. 369 of them were new blood donors with 365 females and 1200 males. The mean average was 30.5 +/- 9.5 years, ranged from 18 to 59 years. HCV ELISA test were positive in 22 plasma samples and one of them were co-infected with hepatitis B (HCV/HBV). Four out of these 22 samples have been confirmed positive to RIBA test and three of them were not determined. HCV seroprevalence were 1.4% after ELISA and 0.25% after RIBA testing. This seroprevalence were similar in male and in female and higher in new blood donors than in regular blood donors. CONCLUSION: Our results reinforce the necessity to screen hepatitis C virus in all Senegalese blood transfusion centres.

Efficacy comparison between anti-malarial drugs in Africans presenting with mild malaria in the Central Republic of Africa: a preliminary study.

Drug resistance to Plasmodium falciparum contributes to major health problems in central Africa and, as a consequence, poverty. We have analyzed the efficacy of three currently available antimalarial drugs to treat symptomatic, uncomplicated P. falciparum malaria in semi-immune adults living in Bangui, Central Republic of Africa. 210 consecutive individuals were enrolled in the survey, of which 45 were excluded. Those having received dihydroartemisin proved significantly less parasitemic than those having received quinine per os or sulfadoxin-pyrimethamin (chi2 = 16.93; p < 0.05), and 75% recovered in two days compared to 57 and 44%, respectively. The 25% who did not recover benefited from a second cure with dihydroartemisin, which proved 100% efficient. The most accurate protocol remains to be established by analyzing clinical and parasitological data and taking into account the economics of the country.

Immune responses to P. falciparum-MSP1 antigen: lack of correlation between antibody responses and the capacity of peripheral cellular immune effectors to respond to this antigen in vitro.

Protective immunity to P. falciparum blood stage infection is thought to be dependent on IgG antibodies, although the mechanisms that underlie such immunity are not clearly understood. One of the antigens thought to be involved in this protective response is MSP1. The present study has examined the levels and distribution of IgG (and IgM) antibodies to the C-terminal 19 kDa fragment of MSP1 in plasma from P. falciparum immune adult Senegalese and the capacity of the peripheral blood mononuclear cells from these patients to either proliferate or secrete IFN-gamma, IL-10 or IL-4 in vitro in response to this antigen. Specific antibodies were found in 74% of individuals' plasma; 44% of mononuclear cells proved capable of proliferating in vitro and IFN-gamma, IL-10 and IL-4 were detected in 37, 23 and 0% of culture supernatants, respectively. No significant association was found between the presence of antibodies and immune cell reactivity under the culture conditions used. This study emphasizes the complexity of the mechanisms responsible for the sustained production of potentially protective antibodies in response to proposed T-cell dependent P. falciparum blood stage antigens.
