Ictère néonatal. Etude des facteurs associés au Centre Hospitalier Départemental de l'Ouéme-Plateau (CHD-OP)

Introduction : l'ictère néonatal est très fréquent dans le monde et est dominé par les ictères à bilirubine libre. Son évolution est le plus souvent favorable mais il peut être grave et engendrer des complications comme une encéphalopathie hyperbilirubinique, une anémie, voire le décès en absence ou en cas de retard à la prise en charge. L'objectif de ce travail était d'étudier les facteurs associés à l'ictère néonatal dans l'unité de néonatologie du CHUD-OP.Méthodes : il s'agissait d'une étude transversale descriptive et analytique qui avait été conduite du 01 juillet 2015 au 30 juin 2016 et avait porté sur tous les nouveau-nés ayant présenté un ictère et admis dans l'unité de néonatologie du service de pédiatrie du CHUD-OP. La saisie et l'analyse des données avaient été faites à l'aide de Epi info 2000 version 3.5.3 et Microsoft Excel 2016. Le test de Pearson avait été utilisé pour les proportions et le test de Student pour la comparaison des moyennes. La différence était statistiquement significative lorsque p est inférieur à 0,05. Résultats : la fréquence hospitalière de l'ictère néonatal était de 11,0% (170, N=1542). Les principales causes retrouvées étaient : l'infection néonatale bactérienne (29,4% ; n=50), l'incompatibilité fœto-maternelle dans les systèmes ABO et rhésus (15,9% ; n=27). La majorité de ces nouveau-nés était guérie et 22,4% (n=38) avaient présenté : une anémie sévère 21,6% (n=25), une encéphalopathie hyperbilirubinémique 18,2% (n=31) et 26 étaient décédés (15,3%). Les nouveau-nés accouchés en dehors de l'hôpital, la prématurité et l'incompatibilité fœto-maternelle dans les systèmes ABO et rhésus étaient des facteurs associés aux complications de l'ictère néonatal. Conclusion : l'organisation de la référence et l'amélioration de la qualité des soins au couple mère-enfant permettra la réduction des facteurs associées à l'évolution défavorable de l'ictère

[Stevens-Johnson syndrome and toxic epidermal necrolysis in Lomé (Togo). Evolutional and etiological profiles of 40 cases]. / Syndrome de Stevens-Johnson et nécrolyse épidermique toxique à Lomé (Togo): profil évolutif et étiologique de 40 cas.

INTRODUCTION: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe cutaneous drug reactions, the prognosis of which largely depends on the quality of their treatment. The purpose of this study was to determine the evolutional and etiological profiles of SJS/TEN in a teaching hospital in Lome (Togo). METHODS: The medical records of patients hospitalized in the departments of dermatology and intensive care of the university hospital center of Lome for SJS/TEN from 1992 to 2001 were reviewed retrospectively. The records of patients retained corresponded to the international classification criteria of SJS/TEN. RESULTS: We collected 40 cases of SJS/TEN (27 cases of SJS, 12 cases of TEN and one overlap SJS/TEN). Patients' mean age was of 30 +/- 7 years. The sex ratio (male/female) was of 1.5 and the mean follow-up after hospitalization was of 2 months (range: 4 weeks to 8 months). The HIV serology was known in 20 cases (13 cases of SJS and 7 cases of TEN). It was positive in 10 cases (5 during TEN and 5 during SJS). Five of the 12 patients (41.7 p.cent) exhibiting NET died (all were HIV-infected) versus 2 of the 27 patients (7.4 p.cent) exhibiting SJS (2 patients were also HIV-infected). The principle drugs incriminated were: antibacterial sulphonamides (16 cases; 40 p.cent), rifampicin-isoniazid combination (7 cases; 17.9 p.cent), anti-epileptics (5 cases; 12.5 p.cent); amino-penicillin (4 cases; 10 p.cent) and non-steroidal anti-inflammatories (2 cases; 5 p.cent). Chinese drugs of undetermined nature were incriminated in 3 cases of SJS. No drug was formally identified in 3 cases of SJS. DISCUSSION: This study confirms the rareness of SJS/NET. These affections are of poor prognosis, particularly in developing countries. The results of this study suggest that the concomitance of an opportunist infection due to HIV-immunodepression is of poor prognosis in the evolution of SJS/NET. Antibacterial sulphonamides and the rifampicin-isoniazid combination are frequently incriminated in Togo.

[Stevens-Johnson syndrome and toxic epidermal necrolysis after intake of rifampicin-isoniazid: report of 8 cases in HIV-infected patients in Togo]. / Syndromes de Stevens-Johnson et de lyell après la prise de rifampicine-isoniazide chez 8 malades infectés par le VIH au Togo.

Dermatological reactions are frequent drug-related complications in patients with HIV infection. The most serious disorders are Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), a.k.a. Lyell's syndrome, that are potentially fatal. The purpose of this report is to describe 8 cases of SJS/TEN observed in Lomé teaching hospital (Togo) after intake of a combination of rifampicin-isoniazid by HIV-infected patients. There were 5 men and 3 women with a mean age of 28 years. All patients presented AIDS. The disorder was SJS in 3 cases and TEN in 5. In 6 cases, manifestations occurred during initiation of treatment (mean delay for onset, 16 days). In the remaining two cases, manifestations occurred 6 days and 8 days respectively after beginning treatment for recurrent tuberculosis. Mean skin detachment was 8% in patients with SJS and 55.7% in patients with TEN. Five patients including 4 with TEN and 1 with SJS died. This study documents incrimination of combined rifampin-isoniazid treatment in the occurrence of SJS/TEN in patients with HIV infection and confirms the severity and poor prognosis of these disorders. The presence of opportunistic infections such as pulmonary tuberculosis may be an unfavourable prognostic factor in immunocompromised patients with these severe dermatological disorders.

Fractal analysis of bone texture on os calcis radiographs compared with trabecular microarchitecture analyzed by histomorphometry.

Microarchitecture of trabecular bone is an important determinant of bone fragility; to date, its evaluation requires bone biopsy with histomorphometry analysis. Methods of noninvasive characterization of trabecular bone microarchitecture are in development and we have developed and validated a bone texture analysis applied to bone radiographs and based on fractal geometry. The aim of our study was to compare this fractal analysis of trabecular bone texture on radiographs to the trabecular microarchitecture analyzed by bone histomorphometry on os calcis biopsies. Thirty eight ossa calcis from 19 human cadavers were studied. Fractal analysis of the trabecular bone of os calcis radiographs was performed by the maximum likelihood estimator following the fractional brownian motion model. The ossa calcis were dissected, then transcortical biopsy cores focused on the fractal analysis region of interest were obtained. Structural and connectivity parameters were measured with both automatic and semiautomatic analyzers. We have found a significant relationship between the fractal Hmean parameter and structural histomorphometric indices; the best correlation was found with trabecular separation (r = -0.55; P = 0.0004). Based on a stepwise regression analysis, trabecular spacing and trabeculae number together would explain 38% of the variance of the fractal parameter. Although the relationship with connectivity indices was poor, our fractal analysis of os calcis trabecular bone texture on radiographs seemed to partially reflect the trabecular bone microarchitecture.

[Systematic parasitic coprologic testing. Value in hospital kitchen staff]. / Examen coprologique parasitaire systématique. Intérêt chez les agents de restauration hospitalière.

The results of annual parasitological coprology in 56 members of the kitchen staff of a hospital over a 6-year period have been studied. Among these subjects, 27 had at least one positive examination. The results were compared with those from other hospitals. Among the parasites found were 2 Strongyloides stercoralis, 4 Schistosoma mansoni and 31 protozoa with direct transmission. The value of this examination is discussed, taking into account the increasing number of immunodepressed patients.
