Association between biological markers of sickle cell disease and cognitive functioning amongst Cameroonian children.

Background: Some of the major complications of sickle cell disease (SCD) occur in the brain and apart from overt stroke, patients also present with cognitive impairments. We sought to evaluate the prevalence of cognitive deficits as well as their biological predicting factors in young SCD patients in Cameroon.

Methods: The cognitive performances of Cameroonian SCD young patients were evaluated using a neuropsychological test battery assessing four domains of cognitive functioning (executive functions, attention, memory, and sensory-motor skills) previously adapted and normalized on healthy subjects in Yaoundé.

HIV-associated neurocognitive disorders in sub-Saharan Africa: a pilot study in Cameroon.

Background: The disease burden of human immunodeficiency virus (HIV)--acquired immunodeficiency syndrome (AIDS) is highest in sub-Saharan Africa but there are few studies on the associated neurocognitive disorders in this region. The objectives of this study were to determine whether Western neuropsychological (NP) methods are appropriate for use in Cameroon, and to evaluate cognitive function in a sample of HIV-infected adults.

Methods: We used a battery of 19 NP measures in a cross-sectional study with 44 HIV+ adults and 44 demographically matched HIV- controls, to explore the validity of these NP measures in Cameroon, and evaluate the effect of viral infection on seven cognitive ability domains.

Neuropsychology in Cameroon: first normative data for cognitive tests among school-aged children.

Introduction: Very few normative data on psychometric tests are available in sub-Saharan African countries, in spite of the obvious needs and potential benefits from psychological and neuropsychological examination in these contexts. The goal of the ongoing overall project is to assess the cognitive functioning of Cameroonian school-aged children suffering from Sickle Cell Disease. For this purpose, normative data on psychometric tests adapted to the Cameroonian cultural context had to first be established.

[Antimicrobial susceptibilities of organisms isolated from patients with urinary tract infections in 2002].

Using the agar dilution method, the antibacterial activity of 18 antibiotics inclusive of 4 carbapenems were investigated against 101 strains of urinary pathogens isolated from patients with urinary tract infections who visited the Department of Urology at Kagoshima University Hospital, between January and December 2002. 4 strains of Staphylococcus aureus, 3 strains of Staphylococcus spp. (exclusive of S.

Renal silica calculi in an infant.

We report on a rare case of urinary silica calculi in a 10-month-old boy. The boy showed acute pyelonephritis with left hydronephrosis. Ultrasonography and computed tomography revealed a calculus at the left ureteropelvic junction and three additional calculi in the left renal pelvis.

[Spontaneous rupture of renal cell carcinoma: a case report].

A 74-year-old man with severe right flank pain and hypochondralgia, was admitted to a hospital where he was found to have an abnormality of the right kidney on computed tomographic (CT) scan. He was referred to our department for further examination and treatment on the next day. Spontaneous rupture of the right renal cell carcinoma was mostly suspected from preoperative clinical findings obtained by ultrasonography.
