Abdominal and pelvic adhesions: Possible role of leiomyomas and skin scar anomaly in profiling high risk patients  [PDF]
Emmanuel Nzau-Ngoma, Jean-Marie Mbuyi-Muamba, Esimo Mboloko, Massamba Lebwaze
Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.41004
Abstract:

Background and aims: Adhesions can cause important morbidity including abdominal and pelvic pain, intestinal obstructions, and infertility. When adhesions are formed, there is no efficient method, nowadays, to resolve them, thus the reduction of their prevalence relies on the prevention. Profiling high risk patients for abdominal and pelvic adhesions (APA) is an important step to this prevention. The risk factors of adhesions in our institution, the association between APA, leiomyomas and skin scar anomaly (SSA) were investigated. Methods: A cross-sectional study was conducted from March 1st to June 30th 2013 including patients who underwent laparotomy or laparoscopy. Patients’ characteristics, presence of a SSA and leiomyomas, as related to adhesions, were analyzed. Student’s t, Pearson’s Khi-square, Fisher’s Exact, Mann-Whitney tests and logistic regression were used. P values < 0.05 were considered statistically significant. Results: The frequency of adhesions was 41.74%. Patients had a mean age of 32.69 ± 8.94 years. Those with a previous abdominal surgery (PAS), SSA and leiomyomas had respectively 12 times [OR: 11.98, CI95 (4.63 - 30.97)], 3 times [OR: 2.79, CI95 (1.16 - 6.71) and 2.5 times [(OR: 2.49, CI95 (1.07 - 5.78)] more adhesions. In logistic regression, a PAS and leiomyomas remained associated significantly to adhesions with p = 0.000 and p = 0.037 respectively. Conclusion: In peritoneal adhesions, leiomyomas and SSA are other factors that may allow a cautious selection of high risk patients who must benefit from particular attention during surgery. Further well designed studies are necessary to investigate the accurate clinical relation among those three conditions.

Abstract: In this paper, we study some aspects of the geometry of leaves of integrable distributions of lightlike hypersurfaces in indefinite Kenmotsu manifolds, tangent to the structure vector field. Theorems on parallel vector field, Killing distribution, geodesibility of lightlike hypersurfaces are obtained. Some characterization Theorems of leaves of integrable distributions are given. We prove that there exists a distribution, subset of the screen distribution, in which, under the integrability condition, any totally contact umbilical leaf is an extrinsic sphere. En este trabajo se estudian algunos aspectos de la geometría de las hojas de distribuciones integrables de las hipersuperficies luminosas en variedades de Kenmotsu indefinidas, tangentes a la estructura de un campo vectorial. Se obtienen algunos teoremas sobre el campo de vectores paralelo, distribución de Killing y geodesbilidad de hipersuperficies liminosas. Se dan algunos teoremas de caracterización de las hojas de las distribuciones integrables. Se demuestra que existe una distribución, subconjunto de la distribución de la pantalla, en la que, bajo la condición de integrabilidad, cualquier contacto con la hoja umbilical es una esfera extrónseca.

Advances in Physical Education (APE) , 2019, DOI: 10.4236/ape.2019.92008
Abstract: The aim of this study was to find the reasons why football isn’t taught in the general and technical schools of Brazzaville,?Congo. A cross-sectional survey, conducted throughout Brazzaville (Congo), targeted?at?a representative sample of50 teachersaged 35 to 49 years. These subjects were teaching physical education in high schools. Our investigation, undertaken from February 2018 to April 2018, was based onof a questionnaire administered to the teachers of physical education evolving in the high schools of Brazzaville?that?was articulated around their representation on it put on football in physical education.The resultsindicate that the reason that football isn’t taught is attributable to the lack of initiative and creativity shown by the teaching of the physical education in high schools in Brazzaville.Our data show the importance of problems associated to football learning among Congolese teachers of physical education.

World Journal of Cardiovascular Diseases (WJCD) , 2016, DOI: 10.4236/wjcd.2016.69034
Abstract: Context: Several studies were conducted on physiology of apnea in scuba diving. No survey has been reported in fighting sports. Objective: To evaluate cardiovascular variations misled by voluntary apnea during groundwork techniques of judo training. Methods: The temporal evolution of heart rate and modifications of the blood pressure have been investigated during cross sectional and experimental study. A total of 28 Congolese judoists took part in the study. The voluntary apnea was achieved by a judoist to try to carry out two kinds of groundwork (hon-gesagatame and kamishiho-gatame). According to the case, Student t test and analysis of variance were used for comparing data. Multivariate analysis was used to evaluate the effect of “type of groundwork technique × category of weight”. Results: Between 0 and 3 seconds, tachycardia has been observed during the static groundwork techniques and then bradycardia occurred to 3 - 9 seconds for the dynamic groundwork techniques : +6.8% of the rest frequency versus -9.4% for hon-gesa; +4.9% versus -13.7% for kami-shiho. Thereafter, it followed a fluctuation of heart rate of 9 - 15 seconds. Beyond, a stagnation was noted for hongesa, whereas a minimal increase (<5%) for kami-shiho. In relation to the systolic arterial pressure, a meaningful rise was recovered: +46.5% (hon-gesa) versus +50.1% (kami-shiho) in static exercise; +43.4% (hon-gesa) versus +43.3% (kami-shiho) in dynamic exercise. The report was similar for the diastolic arterial pressure: +31.5% (hon-gesa) versus 30.0% (kami-shiho) in static exercise; +20.3% (hon-gesa) versus +23.8% (kami-shiho) in dynamic exercise. Conclusion: The apnea consecutive to the hindrance of an exit groundwork technique to judo drags bradycardia increased while exercise realized static posture, and a rise of the arterial pressure.

Abstract: Context: Several studies were conducted throughout the world on heart diseases in children; no data is available in Congolese child. Objective: To evaluate epidemiological profile of Congolese children and teenager carrying cardiovascular diseases. Methods: A descriptive and prospective study was carried out during 4 years in the pediatric department of teaching hospital of Brazzaville, near the children received in consultation of pediatric cardiology. Results: On 41,472 patients admitted in pediatric service, 526 patients were received in consultation for suspicion of heart diseases. Among them, 444 had cardiopathy (incidence of 10.7‰). It was about a congenital heart disease to 316 (60%) incidence of 7.6‰; Acquired heart disease to 128 (24.4%) incidence of 3.1‰. Among congenital heart defects observed frequency of patients with ASD was 20.3%, isolated in 10.1% of cases, and associated with ECD (11.8%). The VSD was observed in 30.1% of cases, and the Tetralogy of Fallot in 10.1% of cases. Among the acquired heart diseases, severe hypo kinetic dilated cardiomyopathy (DCM) was noted in 24.4% of cases. The rheumatic heart diseases accounted for 41.4% of cases. It was mitral regurgitation (33.6%), a mitral stenosis (1.6%). Pericarditis was objectified at 10.1% of the patients. The evolution was favorable for 43.3% of patients. An aggravation of symptoms was observed to 2.7% of patients. Mortality was 11.9% and 71.9% of deaths were observed to not operate carriers of congenital heart disease. 69.9% of dead patients were carrying a cyanogen heart disease. Left to right shunt represented 21.7% of the deaths. Conclusion: Heart diseases are real problem of public health for Congolese children.

Abstract: The aim of this study was to analyze the epidemiology and distribution of combat sports injuries during African Games 2015. A retrospective study was?conducted from November 2016 to February 2017, including all adult patients?aged?consulted by doctor during combat or admitted to emergency medical sport?unit of complex sporting of these Games. The data collected were sex,?time and day of consulting or admission, injury risk, types, location and?causes of injuries. During these African Games, an average injury frequency of about 78.6% has been observed. Contusions (n = 104), sprains and luxations (n = 43), fractures?(n = 40) and wounds (n = 12) were the main injuries observed among 187?athletes. The lower extremities were more frequently affected than the upper extremities (150 cases versus 78 cases). In conclusion, the present study provides the latest knowledge on the frequency and characteristics injuries in combat sports. Injuries are different according to sport in their mechanisms and injury distribution. During African competition and training session, the evaluation and prevention of these factors could decrease the occurrence of such injuries.

Abstract: Consumption of Bushmeat in the Conkouati-Douli National Park, Congo (Brazzaville): Nature of Game and Characteristics of Consumption. In order to identify the species hunted in the Conkouati- Douli National Park (CDNP), Brazzaville (Congo) and to appreciate the methods of consumption of the bushmeat by the bordering populations, 52 hunters from 16 to 62 years old were a surveying over a period of one month and half. The results indicate that hunt to involve rodents, bovidae, various carnivores, suidae, reptiles and birds. However, the african brush-tailed porcupines (Atherurus africanus) and blue duikers (Cephalophus monticola) were the most appreciated animals. The modes of consumption of the bushmeat were diversified. The smoked meat was used most frequently (48.1%) followed by fresh meat consumption (40.2%). All political and legislative measurements are to be necessary to preserve the resources of this protected area.
