Background: Aneurysms of the internal carotid artery within the petrous temporal bone are extremely rare;their true incidence is unknown. The exact cause is unclear: they may be congenital or result from trauma, infection, or radiation. Aim: We report a case of massive otorrhagia and epistaxis from a ruptured aneurysm of the petrous internal carotid artery. Case Presentation: A 34-year-old man presented to our department for the first time with repeated left otorrhagia ongoing for 5 years, left sided pulsatile tinnitus and left conductive hearing loss. In his history, we noted a right hemi-corporeal deficit of sudden onset one month ago and the head-CT showed a left frontoparietal subarachnoid hemorrhage without any visualised vascular malformation. Otomicroscopy showed a pulsatile mass visible at the posterior part of the hypotympanum. There was a right-sided hemiparesis estimated at 2/5 with no disorder of the sensitivity. After hemodynamic stabilization, the patient was discharged from the hospital and treatment was scheduled in interventional radiology and neurosurgery unit. Unfortunately the patient presented at home with a cataclysmic hemorrhage by massive otorrhagia and epistaxis and arrived dead at the emergency unit. Conclusion: The treatment of a petrous carotid aneurysm must be carried out quickly considering the risk of rupture leading to a cataclysmic hemorrhage that can be rapidly life threatening.

Laryngeal tuberculosis is a rare entity. We consider the case of a woman of 62 who presented a one-year evolving chronic dysphonia chart associated with cough, febricula and general health damage. The nasofibroscopy showed a budding ulcerous lesion of the larynx a priori evoking a granulomatous lesion or cancer. The BAAR spits were strongly positive and the radiographic pictures of the thorax, typically evoked a pulmonary tuberculosis. seeing the excellent therapeutic response to TB treatment in 4 months period, the bifocal tuberculosis diagnostic was confirmed.

This study proposed the newly-designed Pelagic and demersal trawls for the fishing vessels operating in Cameroonian waters in pelagic and demersal fishing grounds. The engineering performances of both trawls were investigated using physical modelling method and analytical method based on the predicted equations. In a flume tank, a series of physical model tests based on Tauti’s law were performed to investigate the hydrodynamic and geometrical performances of both trawls and to assess the applicability of the analytical methods based on predicted equations. The results showed that in model scale, the working towing speed and door spread for the pelagic trawl were 3.5 knots and 1.85 m, respectively, and for the bottom trawl net they were 4.0 knots and 1.8 m. At that speed and door spread, the drag force, net opening height, and wing-end spread of the pelagic model trawl were 36.73 N, 0.89 m, and 0.86 m, respectively, and the swept area was 0.76 msup>2sup>. Bottom trawl speed and door spread were 30.43 N, 0.38 m, and 0.45 m, respectively, and the swept area was 0.25 msup>2sup>. The maximum difference between the experimental and analytical results of hydrodynamic performances was less than 56.22% and 41.45%, respectively, for pelagic and bottom trawls, the results of the geometrical performances obtained using predicted equations were close to the experimental results in the flume tank with a maximum relative error less than 12.85%. The newly developed pelagic and bottom trawls had advanced engineering performance for high catch efficiency and selectivity and could be used in commercial fishing operations in Cameroonian waters.

In senegal, tomato (Solanum lycopersicum L.) cultivation is affected by salinity in many agro-ecological zones. The selection of salt tolerant varieties would be an alternative solution to enhance the production. Thus, germination and growth are studied under axenic conditions for five varieties of tomato subjected to increasing concentrations of NaCl [0, 35, 70 and 105 mM], and supplemented in an MS/2 medium for 30 days. The results reveal that salt negatively affects the evaluated parameters. The Rodeo and Lady Nema varieties have the lowest final germination rates (50%) unlike the Mongal variety (55%). These last two varieties have a decrease of 71.78% and 81.28% in the height of the stem, respectively, in the presence of NaCl at [105 mM] while that of the Rodeo variety is 70%. The Xewel variety has the greatest average number of leaves in the presence of [NaCl 35 mM] (4.95 leaves) and [NaCl 70 mM] (4.77 leaves). The Lady Nema variety records the longest taproot length (2.99 cm) unlike the Rodeo variety (2.25 cm) at [NaCl 105 mM]. The Ganila variety reveals the highest number of secondary roots at the concentrations of [0, 35 and 105 mM] of NaCl with, respectively, 4

Introduction: The frequency, severity, cost of treatment, morbidity and mortality of stroke make it a real public health problem. In industrialized countries, strokes are the leading cause of physical disability in adults, the second leading cause of dementia (after Alzheimer’s disease), and the third leading cause of death (after cancer and cardiovascular disease). It’s also a major cause of depression. The objective of our study was to describe the epidemiological, clinical and evolutionary aspects of stroke in the internal medicine department of Tivaouane Hospital. Material and Method: This is a retrospective study carried out from January 1, 2015 to December 31, 2018 on the files of patients hospitalized for stroke in the medical department of the EPs1 in Tivaouane. We took into account all the patients who had a brain CT (computed tomography) scan. We collected data related to socio-demographic characteristics, history, risk factors, reasons for admission, clinical signs, paraclinical examinations, as well as evolution. Results: Out of 1999 patients, 206 files of patients with stroke were collected, i.e. a proportion of 10.3%. Our study population had a mean age of 65.53 years [16 - 97 years]. We noted a clear predominance of women (50.5%). The majority of the population came from the outskirts of Tivaouane (56.7%). Risk factors for stroke were dominated by hypertension (90.3%), dyslipidemia (19.4%), previous stroke (18.9%), and diabetes (16%). The clinical signs were dominated by a motor deficit (94.1%), speech disorders (67.4%) and consciousness disorders (47%). Ischemic strokes were predominant (65%) over hemorrhagic strokes (34.5%). The outcome was generally unfavorable with 14.6% total recovery, 58.7% recovery with sequelae and a case fatality of 26.7%. Conclusion: It emerges from this study that strokes still remain a real public health problem. Knowledge of populations of risk factors as well as their proper management is fundamental in primary preventio

The residual effects of sucrose concentrations (80 or 100 g·L-1) and hormonal treatments (BAP + Kinetin or Coumarin) of tuberization medium on in vitro microtubers germination of three potato varieties (solanum tuberosum L.) so called Aida, Atlas and Odessa, are described. After 3 weeks of incubation at 28℃ ± 1℃, 70% of Aida microtubers variety, previously formed in the MT2 medium [Ms/2 + 80 g·L-1 sucrose], germinated. The best germination rate for varieties Atlas (100%) and Odessa (66.66%) was obtained on microtubers previously formed in the medium MT2 [Ms/2 + 100 g·L-1 sucrose]. The addition of hormones in the tuberization medium allowed optimizing the microtubers germination of the Aida variety unlike the other varieties. Indeed, for the Aida variety, the combination M5 [Kin 2.5 mg·L-1 + Coum 0.025 mg·L-1 + sucrose 80 g·L-1] increased the germination rate from 70% up to 93.33%. The best germination rate (90%), noticed with microtubers of Atlas variety, initially formed in M2 medium [Kin 1 mg·L-1 + BAP 1 mg·L-1 + sucrose 100 g·L-1], was lower than that one (100%) obtained on medium without hormones. For Odessa variety, the maximum germination rate (53.33%) of microtubers, from the medium M4 [Kin 2.5 mg·L-1 + BAP 1 mg·L-1 + sucrose 100 g·L-1], was also lower than that one (66.66%) observed in the medium without hormones. Aida and Atlas varieties thus offer a better germination rate than Odessa after their cold storage.

Introduction: High blood pressure (HBP) is a worldwide health issue responsible of high cardiovascular morbidity and mortality. Even though essential HBP is far the most frequently reported in patients, secondary causes must be known because of their severity and the possibility of aetiological treatment. No recent epidemiological data are available about secondary causes of HBP in black African populations. The aim of this study was to describe aetiological patterns of secondary HBP in patients followed at saint-Louis Hospital. Patients and Method: We conducted a retrospective and descriptive study in regional hospital of saint-Louis. All patients aged ≥15 years old admitted from January 1st 2011 to January 31st 2015 in internal medicine, nephrology, emergency and cardiology departments were included. Clinical, paraclinical data and patients outcomes were collected from medical records. Hypertension was defined according to JNC8 criteria. secondary HBP was considered if explorations identified a clear aetiology to hypertension. statistical analysis was done with Excel 2010 and sTATA 12.0. Results: We included 9253 patients with mean age of 35 ± 12 years (15 - 83 years) and sex-ratio of 1.6. Overall 67.5% of patients had hypertension and secondary causes were found in 10.5% of them. The majority of patients presented clinical symptoms suggesting a secondary cause of HBP and first-line laboratory explorations were normal in half of cases. Renal diseases were responsible for 79.1% of secondary HBP cases mainly dominated by glomerulonephritis (22.6%), vascular nephropathies (18.7%) and autosomal dominant polycystic kidney disease (5.8%). They were followed by preeclampsia (13.6%) and endocrinal aetiologies such as hyperthyroidism (5.8%), hypercorticism (0.5%), pheochromcytoma (0.5%), primary hyperparathyroidism (0.4%) and Conn’s adenoma (0.1%).

In arid and semi-arid regions, the growth and development of cultivated plants, especially tomato (solanum lycopersicum L.), are severely limited by water deficit. Thus, to cope with this constraint, the plant establishes symbiotic relationships with arbuscular mycorrhizal fungi (AMF) in the soil whose extension of the hyphae allows a better and deeper exploration;this notably improves the hydromineral nutrition of the plant. Therefore, the choice of fungal partner becomes crucial for the establishment of a crop in water-deficient soil. In this context, the contribution of AMF to the water stress tolerance of two varieties of tomato plants was assessed under semi-controlled conditions. Parameters, such as the mycorrhizal frequency, intensity of mycorrhization, relative mycorrhizal dependency, growth, and biochemical parameters (carbon, nitrogen, phosphorus, and proline contents) of plants subjected to three levels of water stress (T100, T70, and T30), were evaluated. The highest frequencies and intensities of mycorrhization and relative mycorrhizal dependencies were obtained with plants of the Xewel variety inoculated with Rhizophagus fasciculatus (F: 95.24%, 88.35%, and 13.64%;M: 40.52%, 37.52%, and 11.22%;D: 23.7%, 54.4%, and 78.82%) and in those of the Lady Nema variety inoculated with Claroideoglomus etunicatum (F: 95.12%, 87.01%, and 15.25%;M: 40.66%, 37.99%, and 11.42%;D: 19.27%, 57.01%, and 70.98%), respectively at water regimes of T100, T70 and T30. These same symbiotic couples recorded, at T30, the best survival rates (+ 40%) and the higher aerial (77% and 74%) and root dry weights (80% and 59%). Plants of the Xewel variety inoculated with R. fasciculatus recorded the highest contents of carbon (T70: 30.59% and T30: 21.55%) and phosphorus (T70: 0.18% and T30: 0.17%). Plants of the Lady Nema variety recorded the highest nitrogen contents with 3.51% and 3.20%, respectively at T70 and T30. Plants of the Lady Nema variety, inoculated with C. etunicatum, also re

The considerable post-harvest losses (5% to 40% depending on storage time) due to the high water content level of the onion varieties in senegal are the main cause of the problem of access to local onion all year round. Therefore, drying is one of the techniques that can be used to solve the problem of onion perishability. This study deals with the characterization of naturally convective kinetics drying of four onion varieties in relation to their maturity level. The experiment was carried out using the gravimetric method. The Welch and Turkey statistical tests display a significant difference between the effective diffusivity coefficients depending on the maturity level within each variety and across the four varieties. The effective diffusivity coefficients of the Galmi Violet, safari, Gandiol F1 and Orient F1varieties range from 2.18 × 10−11 ± 2.69 × 10−12 to 1.32 × 10−10 ± 1.17 × 10−11 m2⋅s−1 at a maturity level less than 80%. When the maturity level is greater than 85%, the effective diffusivity coefficients range from 1.30 × 10−11 ± 1.24 × 10−12 to 8.05 × 10−11 ± 8.94 × 10−13 m2⋅s−1. As far as the activation energy is concerned, the study only reveals a significant difference between the varieties whatever the maturity level is. The Galmi Violet variety stands out with an average activation energy of 66.71 ± 0.12 KJ⋅mol−1 K−1 for the maturity level below 80% and 58.74 ± 0.11 KJ⋅mol−1 for the maturity level above 85%. For the three remaining varieties, the average activation energy ranges from 58.15 ± 0.19 to 59.12 ± 0.13 KJ⋅mol−1 for a maturity level less than 80% whereas the rates go from 47.63 ± 0.28 to 49.96 ± 0.77 KJ⋅mol−1 when the maturity level is greater than 85%. In summary, the higher the maturity level is, the lower the effective diffusivity coefficients will be. The same tendency was observed with the activation energy. The Galmi

Redo cardiac surgery increases?mortality and morbidity. The aim of this study was to determine if aprotinin was superior to tranexamic acid concerning control bleeding loss after redo valve surgery. A retrospective study was conducted from January 1994 until December 2014. 221 patients underwent redo cardiac valve surgery and separated into two groups: aprotinin group (n?=?85) and tranexamic acid group (n?=?136). Univariate tests were applied for data analysis. A total of 221 patients were enrolled in this study. This cohort was separated into two groups: aprotinin group (n?=?85) and tranexamic acid group (n?=?136). Euroscore in tranexamic acid group was higher: 5.96 ± 3.04 vs.?5.17 ± 2.83 in aprotinin group?(p?=?0.055). There was no statistical difference in postoperative mortality between the two groups (p?= 0.153). No statistical differences were reported concerning: total blood loss (p?= 0.51), red blood cells transfusion (p?= 0.215), reexploration for bleeding (p?= 0.537) and postoperative renal failure (p?= 0.79). There were statistical differences concerning mechanical ventilation time, which is longer in tranexamic acid group (p?= 0.008) and the use of inotropic drug support, which is more frequent in the tranexamic acid group (p?= 0.001). Our results demonstrated that tranexamic acid and aprotinin reduce transfusion requirement and blood loss. Due to financial reason, we chose tranexamic acid in preventing blood loss in redo valve surgery.
