Place of urolithiasis in the spectrum of urological pathologies, practices and use of endourological procedures in the management of calculi of the upper urinary tract: results of a survey of referral centres in Africa.

Our aim was to determine the current trend of endourology in the management of upper urinary tract calculi in Africa reference centres. We conducted an online multiple-choice questionnaire survey involving 46 centres from 27 countries using a structured well-designed Google Form (®) questionnaire. The questionnaires were distributed to the head of service through their emails.

Fatty liver and atherogenic dyslipidemia have opposite effects on diabetic micro- and macrovascular disease.

Background And Aims: Non-alcoholic fatty liver (FL) is comorbid with obesity, metabolic syndrome and type 2 diabetes. Atherogenic dyslipidaemia (AD), frequent in FL, is associated with risk of micro- and macrovascular complications. Given the paradoxical ocular protection of FL in T2DM, we studied how FL modulates micro- and macrovascular complications as a function of AD.

Oncogenic human papillomavirus in breast cancer: molecular prevalence in a group of Congolese patients.

Background: Since the work of Band . in 1990 ( 87:463-467), several studies have suggested a possible link between the pathogenesis of breast cancer and viral infection. Infection with oncogenic HPV has been one of the viruses implicated in breast cancer cases worldwide.

[Evaluation of the Follow-Up and State of Adolescents with Sickle-Cell Disease in Brazzaville (Congo)].

The experience of the adolescent with homozygous sickle-cell disease is influenced by several factors that differentiate it from the older child entirely dependent on his parents. The objective of this study was to describe the state of health and to assess the quality of follow-up and to identify the determinants of poor monitoring of adolescent sickle-cell followed in Brazzaville for an average of 12 ± 9.6 years, starting from a cross-sectional study carried out at the Brazzaville University Hospital from March to September 2016.

[Pterygium surgery by conjunctiva autograft with autologous blood fixation].

Introduction: Pterygium surgery is marked by the possibility of recurrences; one of the techniques which results in the least recurrences is conjunctival autograft. Fixation of the conjunctiva had traditionally been accomplished with sutures. In recent years, conjunctival grafting has also been performed with fibrin glue.

[Intraocular pressure decrease after manual small incision cataract surgery].

Purpose: We decided to evaluate the decrease in intraocular pressure six months after cataract surgery.

Materials And Methods: We evaluated patients' IOP using an applanation tonometer. The patients then underwent cataract surgery.

Size, density and cholesterol load of HDL predict microangiopathy, coronary artery disease and β-cell function in men with T2DM.

The role of high-density lipoprotein cholesterol (HDL-C) as modifiable risk factor for cardiovascular (CV) disease is increasingly debated, notwithstanding the finding that small-dense and dysfunctional HDL are associated with the metabolic syndrome and T2DM. In order to better clarify the epidemiological risk related to HDL of different size/density, without resorting to direct measures, it would seem appropriate to adjust HDL-C to the level of its main apolipoprotein (apoA-I), thereby providing an [HDL-C/apoA-I] ratio. The latter allows not only to estimate an average size for HDLs, but also to derive indices on particle number, cholesterol load, and density.

The normal-weight type 2 diabetes phenotype revisited.

Background: Type 2 diabetes (T2DM) is associated with obesity, insulin resistance and the metabolic syndrome (MetS). In non-diabetic populations, features of metabolic obesity (MO) are observed in a minority of normal-weight (NW) subjects. The cardiometabolic status of metabolically obese but normal-weight (MONW) individuals has not yet been phenotyped in T2DM.

How to transform a metabolic syndrome score into an insulin sensitivity value?

Background: The metabolic syndrome (MetS) predicts cardiovascular risk and incident type 2 diabetes mellitus. The presence of a MetS is defined by the clustering of ≥3 out of 5 cardiometabolic criteria (hyperglycemia; hypertension; enlarged waist; low high-density lipoprotein-cholesterol; and hypertriglyceridemia), each of which is connected with insulin resistance. It is not known whether the severity of MetS, ranked from the sextet of scores range [0/5 to 5/5], is linearly related to reduced insulin sensitivity (IS) and/or lesser hyperbolic product across the glycemic spectrum.

Baseline diabetes as a way to predict CV outcomes in a lipid-modifying trial: a meta-analysis of 330,376 patients from 47 landmark studies.

Background: Diabetes is a major cardiovascular risk factor. However, its influence on the rate of occurrence of cardiovascular (CV) events during a clinical trial that included a diabetes subgroup has not yet been quantified.

Aims: To establish equations relating baseline diabetes prevalence and incident CV events, based on comparator arms data of major lipid-modifying trials.

Novel determinants preventing achievement of major cardiovascular targets in type 2 diabetes.

Background: T2DM management requires tight control of 3 critical quality indicators to prevent vascular complications: LDL-C, SBP, and HbA1c. This study evaluated the rate of T2DM patients attaining these critical quality indicators, and the pathophysiological or cardiometabolic traits predicting goal achievement.

Patients And Methods: Cross-sectional analysis evaluating combined goal achievement (LDL-C<100 mg/dL; SBP<130 mmHg and HbA1c<7.

[Tooth decay in school environment at Brazzaville (Congo)].

Aim: To determine the frequency of dental caries and habits that can be the cause of this disease in Brazzaville.

Methods: A prospective study was conducted in primary schools between February and May 2010. This study involved a sample of 307 students of both sexes, aged 4-15 years from school in the city of Brazzaville.

[A case of isolated tuberculosis of the appendix at the University Hospital Center in Brazzaville, Congo].

Since the outbreak of human immunodeficiency virus (HIV) infection, extrapulmonary tuberculosis has become increasingly frequent in developing countries. The purpose of this report is to describe a case of isolated tuberculosis of the appendix diagnosed following generalized peritonitis in a 53-year-old man. The appendix is the least frequent gastrointestinal location of isolated tuberculosis.

[Heart failure in elderly patients in Brazzaville, Congo: clinical and etiologic aspects and outcome].

[Severe malaria associated with acute renal insufficiency: apropos of a case].

Renal insufficiency as a complication of severe malaria is a rare pathology. A case was observed in young girl aged 10.5 years following Plasmodium malaria fever.

Disseminated African histoplasmosis in a Congolese patient with AIDS.

We report the first Congolese case of African histoplasmosis in a patient with AIDS which represents the third case to be described in the literature. This contrasts with the now frequent occurrence of Histoplasma capsulatum histoplasmosis in HIV-infected subjects in North America; the difference is likely to be due to differences in exposure to the fungus rather than to differences in behaviour of the fungus or in the epidemiology of HIV.

[Epidemiological status of onchocerciasis in the Congo].

Analysis of 25 surveys carried out in the Congo between 1978 and 1987 (covering nine of the ten administrative regions), during which 6,215 subjects were examined, showed that onchocerciasis is endemic in the southern part of the country. Two main foci meeting at the southern exit of Brazzaville (Pool region) were identified. One focus in the Djoué basin.

[Loa loa filariasis: cause of severe eosinophilia].

Two cases of very high hypereosinophilia (28,160 and 11,232/mm3) observed in congolese patients are presented. Although microfilaraemia was not detectable, loiasis was diagnosed, given the clinical manifestations, epidemiological data, history of sub-conjunctival migration of the adult worm (in one case), spectacular recovery (clinical and biological) after treatment with diethylcarbamazine. This "allergic form" of filariasis is often considered unusual in indigenous subjects.
