Academic optimism, capital indicators as predictors of cognitive, affective, and psychomotor learning outcome among students in secondary school. Hierarchical regression approach (HRA).

Background: Studies that were carried out previously on learning outcomes focused mainly on the student's cognitive domain while identifying factors that predicted it. More so, most of the learner's assessments in school are largely dependent on the score obtained from specific subjects by the learner, and efforts to address other domains of instruction such as affective and psychomotor domains have been minimal or absent in regard to the variables selected for the study. This study therefore sought to address that gap by finding out the relative and composite contribution of academic optimism and capital indicators to the learning outcomes (of students.

[Epidemiology of urologic cancers at the university teaching hospital of Cotonou, Benin. Review of about 158 cases of urologic cancers].

Objective: To study the epidemiological profile of urologic cancers in the department of urology at the teaching hospital of Cotonou.

Methodology: We analysed the course of all urological cancer data over a 42-month period, from January the 1st 2008 to 30th June 2011.

Results: Urologic cancers were frequent in our hospital practice with a frequency of 17.

Prevention of venous thromboembolism among inpatients at Cotonou teaching hospital, Benin.

Aim: The aim of this retrospective study was to evaluate the use and appropriateness of preventive measures for venous thrombosis among adult inpatients in a Benin teaching hospital.

Patients And Methods: All patients were systematically enrolled. The risk of venous thrombosis was estimated according to international guidelines.

Novel amphiphiles with preorganized functionalities-formation of Langmuir-films and efficiency in mineral flotation.

Based on the principle of supramolecular preorganization, three different types of new oligofunctional surfactants have been designed and prepared differing in both the degree of conformational flexibility and the hydrophilic-lipophilic balance of their structures due to the chosen building blocks including rather rigid and shape-persistent backbones or a dendritic subunit. Surface-active properties of the oligofunctional surfactants involving critical micellization concentration, surface tension at cmc, effectiveness of surface tension reduction, and the efficiency of adsorption were determined by use of the surface tension isotherms, respectively. In particular the amino-acid-based amphiphiles show remarkable surface-active properties with the adsorption at the air/water interface and also the aggregation to micelles starting at very low concentration.

[Vesicouterine fistula: report on 15 cases at Cotonou University Urology Clinic].

Objective: To analyse the clinical and radiological features of cases of vesicouterine fistula (VUF) seen in the department and the results of treatment in order to improve the therapeutic management of patients with VUF.

Material And Methods: The medical records of 17 woman admitted to the department and treated for vesicouterine fistula between 01/01/1994 and 15/06/2001 were reviewed. Two were excluded from this essentially retrospective study, as they were considered to be uninterpretable due to missing data.

[Embryonal botryoid rhabdomyosarcoma of the bladder].

A 10-year-old black child presented with bloody urine and urine retention due to a bladder tumor. Cystoprostetatectomy led to the diagnosis of embryonal botryoid rhabdomyosarcoma. At gross examination, tumor presented a grape-shaped form.

[Penile-perineal-scrotal gangrene. Epidemiologic, diagnostic, and therapeutic features. Report of 32 cases].

The authors analyse the epidemiological, diagnostic and therapeutic aspects of peno-perineo-scrotal gangrene in the urology department of a university hospital of a developing African country. The frequency of this disease is low, four cases per year, and most patients (about 72%) are between the ages of 40 to 70 years. The authors identified urethral stricture (31.

[Urethral diseases in children at surgical departments of the Cotonou Hospital. Apropos of 77 cases].

Over a 6-year period in the surgical departments of Cotonou hospital, urethral diseases in children represented 20% of all infantile urological diseases and essentially consisted of urethral strictures (26 cases), hypospadias (22 cases), posterior urethral valves (12 cases), prolapsed urethral mucosa, the only disease observed in girls (9 cases). These diseases generally do not raise any diagnostic problems, but the real problem concerns follow-up of these children, who are usually lost to follow-up after discharge.

[Buschke-Loewenstein tumor. Apropos of 2 cases in Cotonou, Benin].

About two cases of Buschke-Loewenstein tumor--one of the penis in man infected with HIV and another of perianal area-, the authors insist on the relative frequency of Buschke-Loewenstein tumor in non-circumcised and homosexual groups. They emphasize the continuous precancerous spectrum of Buschke-Loewenstein tumor.
