La pneumopathie aigue bactérienne communautaire du sujet âge en pneumologie au centre hospitalier et universitaire du point-g, Bamako-mali / Community acute bacterial pneumonitis of the subject age in pulmonology at the Point-g hospital and university center, Bamako- Mali

Introduction : Les pneumopathies aiguës bactériennes (PAB) communautaires sont des infections respiratoires basses aiguës, non suppurées, non tuberculeuses du parenchyme pulmonaire acquises au sein de la communauté. Elles ont une présentation clinique atypique et un mauvais pronostic chez le sujet âgé. Matériels et Méthodes : Il s'agissait d'une étude transversale prospective menée au service de pneumologie du centre hospitalier universitaire (CHU) du Point-G, du 30 Octobre 2018 au 30 Septembre 2019. L'objectif était de déterminer les particularités cliniques, étiologiques, thérapeutiques et évolutives de la PAB chez le sujet âgé. Ont été inclus tout âge ≥ 65 ans, présentant des signes cliniques et radiologiques d'une PAB Résultats : Durant la période d'étude 85 patients répondaient aux critères d'inclusion sur 178 hospitalisés. Le sex-ratio était de 3/1. Environ 2/3 étaient tabagiques et 11% était positif au VIH. La fièvre n'était pas constante enregistrée dans 51,76% des cas. Les signes respiratoires étaient dominés par la toux (96, 47%), la dyspnée (94, 11%) et extra respiratoires par le trouble de la conscience. Le Klebsiellapneumoniae était le germe le plus retrouvé. L'antibiotique le plus utilisé était l'amoxicilline-acide clavulanique. La durée moyenne d'hospitalisation était de 9 jours. La mortalité était de 19%. Conclusion: La PAB chez le sujet âgé est d'une symptomatologie clinique frustre. Elle est grave avec une surmortalité

Introduction: Community-acquired acute bacterial pneumonia (ABP) is an acute, non-suppurative, non-tuberculosis lower respiratory infection of the lung parenchyma acquired within the community. They have an atypical clinical presentation and a poor prognosis in the elderly. Materials and Methods: This was a prospective cross-sectional study conducted in the Pneumology department of the University Hospital Center (CHU) of Point-G, from October 30, 2018, to September 30, 2019. The objective was to determine the clinical, etiological, therapeutic and progression of BAP in the elderly. Were included any age ≥ 65 years, presenting clinical and radiological signs of a PAB. Results During the study period, 85 patients met the inclusion criteria out of 178 hospitalized. The sex ratio was 3/1. About 2/3 were smokers and 11% were HIV positive. Fever was not constant recorded in 51.76% of cases. Respiratory signs were dominated by cough (96.47%), dyspnea (94.11%) and extra respiratory by impaired consciousness. Klebsiella pneumoniae was the most found germ. The most commonly used antibiotic was amoxicillin-clavulanic acid. The average length of hospitalization was 9 days. Mortality was 19%. Conclusion: The PAB in the elderly is of a frustrating clinical symptomatology. It is serious with excess mortality

[Health impact of exposure to pollens: A review of epidemiological studies]. / Impact sanitaire des pollens : revue des études épidémiologiques.

The aim of this review is to describe the health impact of exposure to pollen based on recently published epidemiological studies. The methodology chapter, describes a review of the literature and outlines important elements of these studies: measurement of exposure to pollens, study types used, study populations and the health indicators related to pollen exposure. In this review, two types of studies have been used to assess the epidemiological evidence of short-term links between pollen exposure and hay fever or asthma. Ecological time-series studies use daily indicators of asthma exacerbations (emergency room admissions or hospitalizations), consultations for rhinitis or conjunctivitis, or anti-allergic drug consumption within general population. Panel studies relate measurements of pollen grain concentrations to nasal, ocular and bronchial symptom severity in a group of subjects sensitized to a specific pollen, monitored during the pollen season. In both cases, the studies show a relationship on a day-to-day basis between health indicators and daily rates of atmospheric pollen collected by a pollen trap. These studies take into account confounding factors, such as air pollution, weather factors and sometimes exposure to outdoor molds. Unlike earlier studies, more and more studies focus on the shape of the dose-response relationship and the lag between pollen exposure and symptoms. Only rarely, individual susceptibility factors, the clinical phenomenon of priming and polysensitization are reported. Thus, ecological time-series studies and panel studies assess respectively the impact of pollen exposure in the general population and in groups of sensitized patients. Using appropriate statistical tools, these studies provide insight into the shape of the dose-response relationship, with a potential threshold below which symptoms are absent, then a linear relationship for nasal, ocular and bronchial symptoms and a plateau where the symptoms do not increase despite the continued increase in pollen.
