Introduction: Cranioencephalic trauma caused by bladed weapons is rare, and that caused by sharp objects is exceptional. The aim of our study was to describe the clinical, therapeutic and evolutionary aspects. Materials and method: This was a descriptive and analytical study over a 48-month period at CHU la Renaissance from January 1, 2018 to december 31, 2021, concerning patients admitted for penetrating cranioencephalic trauma by pointed object. Results: Twelve cases, all male, of penetrating cranioencephalic sharp-force trauma were identified. The mean age was 34 ± 7 years, with extremes of 11 and 60 years. Farmers and herders accounted for 31% and 25% of cases respectively. The average admission time was 47 hours. Brawls were the circumstances of occurrence in 81.2% of cases. Knives (33%), arrows (25%) and iron bars (16.6%) were the objects used. Altered consciousness was present in 43.8% of cases, and focal deficit in 50%. Scannographic lesions were fracture and/or embarrhment (12 cases), intra-parenchymal haematomas (6 cases) and presence of object in place (4 cases). Surgery was performed in 11 patients. Postoperative outcome was favorable in 9 patients. After 12 months, 2 patients were declared unfit. Conclusion: Penetrating head injuries caused by sharp objects are common in Chad. Urgent surgery can prevent disabling after-effects.

Introduction: Human papillomavirus (HPV) infection is the most widespread sexually transmitted infection in the world. Today, there is growing evidence that HPV can be transmitted early in life, and one potential route is mother-to-child transmission. Data on this route of HPV transmission are scarce in Africa and particularly in Burkina Faso, where no data on the subject are yet available. The aim of our study was to estimate the rate of mother-to-child transmission of HPV infection and to identify circulating genotypes. Methodology: Cervico-uterine samples were collected from 100 full-term pregnant women and, buccal samples were obtained from their newborns at Hopital Saint Camille de Ouagadougou (HOSCO) by the specialist physician. HPV DNA amplification and genotyping were performed by PCR followed by hybridization using the HPV Direct Flow Chips kit, detecting 36 genotypes including 18 high-risk and 18 low-risk. Results: The prevalence of HPV in newborns was 8% (8/100). Six (6) HPV-positive neonates had HPV-positive mothers, while 2 HPV-positive neonates had HPV-negative mothers. The vertical transmission rate was 26.09% (6/23). Mother-newborn genotypes were concordant. However, the genotype profile of the newborns was more restricted than that of the mothers. Conclusion: HPV DNA was found in 8% of newborns in our study. The genotype profile of the mother-newborn pair was concordant. Asymptomatic HPV infection in a pregnant woman could constitute a risk factor for vertical transmission.

High-gain and low-distortion Brillouin amplification based on pump multi-frequency intensity modulation

引用

Chinese Physics B 2019年第2期28卷 277-282页

作者： Li-Wen Sheng de-Xin ba Zhi-Wei Lv National Key Laboratory of Science and Technology on Tunable Laser Harbin Institute of Technology

Using a pump with a multi-line spectrum to broaden the Brillouin gain bandwidth is an effective way to achieve lowdistortion amplification with high gain. Here, we theoretically and experimentally investigate the generation of a broadband Brillouin gain spectrum based on multi-frequency intensity modulation in an optical fiber. The arbitrary bandwidth of the Brillouin gain spectrum of stimulated Brillouin scattering(SBS) can be obtained as expected. In our experiment, a broadband Brillouin gain spectrum with a bandwidth of about 200 MHz is demonstrated. We also achieve a low-distortion amplification of a weak signal, whose maximum magnification is 65 d B for a-68-dBm input power signal.

Introduction. Hyperprolactinemia represents a supraphysiological secretion of prolactin. In clinical practice, it is the most frequently encountered anterior pituitary disorder. However, its real prevalence is little known in Africa. The purpose of this study is to list all cases of hyperprolactinemia over the past four years and to make an inventory of the various etiologies found and their management. Methodology. This is a cross-sectional descriptive study on the files of patients who came for consultation in the internal medicine and endocrinology department with hyperprolactinemia retrospectively collected from January 2017 to december 2020. Included were patients followed or whose the diagnosis of hyperprolactinemia was established in endocrinological consultation during the study period. Results. This study recorded 26 cases of hyperprolactinemia. The female sex represented 73.08% (sex ratio M/F 0.37) and the average age was 33.92 years. The 40 - 50 age group was the most represented with 30.77%. In women, galactorrhea accounted for 73.07%, amenorrhea 57.69% of clinical pictures and infertility 23.08%. In men, infertility accounted for 7.69% of presentations, gynecomastia 11.54% and erectile dysfunction 15.38%. The duration of evolution of the signs was 4 months in 23.08% of the patients. The mean prolactinemia was 702.58 ng/ml. CT was performed in 80.85% of patients. The main etiologies were pituitary adenomas (77%). All our patients were treated with dopaminergic agonists. Cabergoline was prescribed in 77% of patients. The evolution was favorable in 96.25% of patients. Conclusion. Hyperprolactinemia is a pathology that exists in our regions. The main etiology remains pituitary adenomas and treatment with cabergoline.

Giant cerebriform nevus cell nevus of the scalp is an extremely rare form of congenital melanocytic nevus. Giant cerebriform nevus of the scalp has a major psychosocial impact because of its unsightly appearance with fetid maceration. We report the case of a 35-year-old woman who had a painless, malodorous swelling of the cerebriform scalp measuring 20 × 17 cm in diameter with a wide base of insertion at the occipital level adhering to the deep planes. The excision associated with a skin plasty was carried out. Histology concluded that there was a giant cerebriform naevo-cellular nevus of the scalp.

为了探究磺胺类抗生素对污水生物脱氮的影响及相关机制,采用序批式生物反应器(SBR)工艺运行模式,投加不同剂量磺胺甲恶唑(SMX),评估了SMX对全程生物脱氮性能的影响。结果表明,低浓度(0.1 mg/L)SMX对生物脱氮性能污泥特征影响不显著,而高浓度SMX(>0.5 mg/L)降低了生物脱氮效率,提高了污泥胞外聚合物(EPS)含量、降低污泥浓度、抑制了生物硝化和反硝化过程。SMX在生物脱氮系统内去除受初始SMX浓度影响,且初始SMX浓度越高,SMX的去除效率越低。当SMX为2.0 mg/L时,化学需氧量(COD)、氨氮和总氮(TN)去除效率分别下降至76.5%~79.2%,80.6%~84.6%和71.6%~73.4%,EPS含量提高至89.8~91.3 mg/g,污泥蛋白质与多糖比值提高至2.91~2.97,污泥浓度降低至3.41~3.52 g/L。高浓度SMX显著抑制了硝化和反硝化过程,从而导致生物脱氮效率下降。研究结果丰富了SMX在水体内全程生物脱氮系统内影响行为,为SMX风险管控提供一定借鉴。
