Toxicol Rep 2016; 3:826-831. [PMID: 28959610 PMCID: PMC5616082 DOI: 10.1016/j.toxrep.2016.10.004] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Revised: 10/14/2016] [Accepted: 10/14/2016] [Indexed: 11/24/2022] Open
Abstract
Isoniazid (INH), recommended by WHO (World Health Organization) in the treatment of tuberculosis (TB), is metabolized primarily by the genetically polymorphic N-acetyltransferase 2 (NAT2) enzyme. The human population is divided into three different phenotypic groups according to acetylation rate: slow, intermediate, and fast acetylators. The objective of this study was to explore the relationship between NAT2 genotypes and the serum concentrations of INH. Blood samples from 96 patients with TB were taken for the analysis. NAT2 polymorphisms on coding region were examined by polymerase chain reaction (PCR) direct sequencing; the acetylation status was obtained by measuring isoniazid (INH) and its metabolite, acetylisoniazid (AcINH) in plasma was obtained by using the liquid chromatography coupled to mass spectrometry. TB patients were distributed into two groups of fast and slow acetylators according to the acetylation index calculated based on the plasma concentration of INH in the 3rd hour (T3) after an oral dose. Our PCR analysis identified several alleles, where NAT2*4, NAT2*5A, NAT2*6A, and NAT2*13A were the most important. The concentrations of INH varied between 1.10 mg/L and 13.10 mg/L at the 3rd hour and between 0.1 and 9.5 mg/L at the 6th hour. The use of the acetylating index I3 allowed the classification of tested patients into two phenotypic groups: slow acetylators (44.3% of TB patients), and rapid acetylators (55.7%). Patient’s acetylation profile provides valuable information on their therapeutic, pharmacological, and toxicological responses.

Abstract
The purpose of the study was to determine Pb and Cd concentrations in humans and to assess the effect of co-exposure to these metals on biomarkers of oxidative stress and nephrotoxicity. Blood and urine levels of Pb and Cd, oxidative stress and urinary renal biomarkers were measured in 77 subjects neighboring a discharge and 52 in the control site. Exposed subjects showed significantly higher levels of lead and cadmium in blood and urine than the controls. Excessive production of reactive oxygen species induced by these metals in exposed subjects conducted to a decrease in antioxidant defense system (GPx, Selenium, GSH) and an increase in lipid peroxidation (MDA). Moreover, changes in markers of nephrotoxicity (high urinary concentrations of total protein, RBP and CC16, as well as GSTα and LDH increased activities) suggested the occurrence of discrete and early signs of impaired renal function for the discharge neighboring population.

Abstract
We report an exceptional association of metacarpal and clavicular tuberculosis in a two-year-old child with SAFA2 sickle cell disease. We emphasize the role of imaging (X-ray and CT scan) in this work. The definitive diagnosis is confirmed by the pathological examination of biopsy samples. This location should be known in endemic tuberculosis areas.

Abstract
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.

Abstract
We report four cases of uterine fistula found with the multidetector CT virtual hysterosalpingography. Patients were received for suspicious of a utero-peritoneal fistula at hysterosalpingography. They were young people at childbearing age (average age of 33 years), multigravidae, two of whom were nulliparous, one primiparous and one multiparous. We noted a history of voluntary interruption of pregnancy by curettage and a cesarean section. For the opacification, we used the classic hysterography standard equipment by means of 1/5 diluted iodine with saline solution as contrast. The multidetector CT virtual hysterosalpingography revealed small uterine perforations including three which were located in uterine posterior face at cervico-isthmic area and corporeal area, bringing about a utero-peritoneal fistula. The multidetector CT virtual hysterosalpingography is a simple and powerful technique for the diagnosis of utero-peritoneal fistula. It is convenient and then deserves an important place in the evaluation of uterine fistula.

Abstract
AIMS The aim of this study was to determine sociodemographics, clinical and therapeutic aspects in patients with isolated mandibular fractures in the Bamako dentistry teaching hospital (CHU-OS). MATERIALS AND METHODS We carried out restrospective study over a period of four months involving isolated mandibular fracture cases, confirmed by a clinical and radiological examination in 2006. The data were collected from medical records, entered and analyzed using Epiinfo.fr 6.0 software. RESULTS The lesions involved 42 men and 13 women with a sex ratio of 3.23. The age group of 21-30 was the most affected. The main cause was found to be road traffic accidents with 72.72 % of the total cases. The fractures of the mandible at the level of horizontal branch were the most frequent with 34.54 %. The orthopedic treatment was used in 72.72 % of the cases, with a good and very good results. CONCLUSION This study shows the high frequency of isolated fractures of the mandible mainly from road traffic accidents, as well as their occurrence among young adults.

Abstract
The annulus is an electron-dense ring structure connecting the midpiece and the principal piece of the mammalian sperm flagellum. Proteins from the septin family have been shown to localize to the annulus. A septin complex is assembled early in spermiogenesis with the cochaperone DNAJB13 and, in mature sperm, associates with Testis Anion Transporter 1; SLC26A8 (Tat1), a transmembrane protein of the SLC26 family. Studies in mice have shown that the annulus acts as a barrier to protein diffusion and controls correct organization of the midpiece. Consistent with these findings, absence of the annulus is associated with flagellum differentiation defects and asthenozoospermia in humans.

Abstract
Ectopic pregnancy is one of the most frequent hemorrhagic emergencies encountered in gynecology and obstetrics. The purpose of this 16-month descriptive prospective study at the Ignace Deen Gynecology-Obstetric clinic at Conakry University Hospital in Guinea was to assess diagnostic techniques and therapeutic attitudes regarding ectopic pregnancy in a low-resource setting. The frequency of ectopic pregnancy was 1.4%. Mean patient age was 28.9 years. Ectopic pregnancy was often observed at the second or third pregnancy (47.1%) in women who were giving birth for the second or third time (36.0%) and had a history of sexually transmitted infections (88.2%) or abortions (43.1%). Most women had no schooling (60.8 %), were poor and lived in a marital home (86.3%). Presenting symptoms included the classic triad of amenorrhea (98.0%), abdominopelvic pain (92.2%), and vaginal bleeding (62.7%). Definitive diagnosis was achieved by ultrasound examination in 76.6% of cases and by puncture of the Douglas pouch in 84%. The most frequent site of ectopic pregnancy was the ampulla of the uterine tube (66.9%). Abdominal and ovarian pregnancy was observed in 3 and 4 of the 51 cases respectively. Surgical management was performed in all cases. The most frequent procedure was salpingectomy (80.3%). Proper treatment of sexually transmitted infections (STI), start-up of post-abortion care facilities, and provision of information during early consultation at the first signs of pregnancy would help reduce the frequency and improve the prognosis of ectopic pregnancy.

Abstract
RhoGTPases (Rho, Rac, and Cdc42) are known to regulate multiple functions, including cell motility, adhesion, and proliferation; however, the signaling pathways underlying these pleiotropic effects are far from fully understood. We have recently described a new RhoGAP (GTPase activating protein for RhoGTPases) gene, MgcRacGAP, primarily expressed in male germ cells, at the spermatocyte stage. We report here the isolation, through two-hybrid cloning, of a new partner of MgcRacGAP, very specifically expressed in the male germ line and showing structural features of anion transporters. This large protein (970 amino acids and a predicted size of 109 kDa), we provisionally designated Tat1 (for testis anion transporter 1), is closely related to a sulfate permease family comprising three proteins in human (DRA, Pendrin, and DTD); it is predicted to be an integral membrane protein with 14 transmembrane helices and intracytoplasmic NH(2) and COOH termini. In situ hybridization studies demonstrate that Tat1 and MgcRacGAP genes are coexpressed in male germ cells at the spermatocyte stage. On testis sections, Tat1 protein can be immunodetected in spermatocytes and spermatids associated with plasma membrane. Two-hybrid and in vitro binding assays demonstrate that MgcRacGAP stably interacts through its NH(2)-terminal domain with the Tat1 COOH-terminal region. Expression of Tat1 protein in COS7 cells generates a 4,4'-diisothiocyano-2,2'-disulfonic acid stilbene and chloride-sensitive sulfate transport. Therefore we conclude that Tat1 is a novel sulfate transporter specifically expressed in spermatocytes and spermatids and interacts with MgcRacGAP in these cells. These observations raise the possibility of a new regulatory pathway linking sulfate transport to Rho signaling in male germ cells.

Abstract
Hemolytic uremic syndrome (HUS) is an nonexceptional complication of infectious gastroenteritis. No one has already been reported in Senegalese publications. We made a retrospective study of the record of 7 patients with HUS among 256 cases of children with bloody diarrhea presenting to the pediatric unit of Aristide Le Dantec between august 1998 and july 1999. The mean age of the children was 33,14+/-25 months and the weight was -2,29 DS. The diagnosis is supported by the findings of an acute renal failure with urea at 1,28+/-0,51g/ l and creatinine at 41,46+/-25,48mg/l. An hemolytic anemia was constant, the blood film revealed schizocytes. We found a thrombocytemia only in two cases. A hight white blood cell count (more than 50000/mm3) was noted in for cases. Only one child made a good recovery. We insist on preventing gastroenteritis and aggressive and adapted management of the HUS.

Abstract
Nearly 200 million people in the developing world are dependent or urban gardening for food and income. This practice has been accelerated by the droughts of recent decades which have forced more and more migrants into urban areas. Numerous potential health hazards have been attributed to urban gardening but the exact risks in Sahelian areas remain unclear. The purpose of this cross-sectional study was to evaluate the incidence of diarrhea at the Tel Zatar gardening site in urban Nouakchott, Mauritania. In addition, a case-control study was carried out to identify risk factors for diarrhea in function of gardeners' activity and living conditions. Statistical analysis was performed using univariate and logistical regression methods. The annual incidence of diarrhea ranged from 6.9 (IC95 p. 100 = 5.0-8.8) to 8.5 (IC95 p. 100 = 6.2-10.8) episodes per gardener and year. Multivariate analysis identified four significant risk factors. Two of these factors were unrelated to gardening, i.e., not having spent more than USD 3.50 the previous day (odds ratio (OR = 2.8, IC95 p. 100 = 1.01-7.81) and poor food hygiene (cooking outside (OR = 4.69, IC95 p. 100 = 1.06-20.83). The other two factors were regular consumption of raw vegetables (OR = 25.5, IC95 p. 100 = 2.0-32.0) and use of untreated well water (OR = 3.85, IC95 p. 100 = 1.08-14.29). Unprotected well water was the cause of 59.2 p. 100 of diarrheal episodes reported by gardeners at Tel Zatar. The results of this study confirm that vegetable production in urban gardens such as Tel Zatar is associated with health risks. Public health measures should address not only the garden sites but also domestic hygiene.
