[Community acute bacterial pneumonitis of the subject age in pulmonology at the Point-g hospital and university center, Bamako-Mali]

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.

OBJECTIVE

To assess the reduction in IOP and ocular symptoms in patients newly diagnosed with POAG and treated with latanoprost as monotherapy.

PATIENTS AND METHOD

A multicentric, cross-sectional, descriptive study was conducted. We included adults newly diagnosed with POAG. All patients received one drop of preserved latanoprost 0.005% in each eye every night for 12 weeks. Changes in IOP and ophthalmic signs and symptoms were assessed during and at the end of treatment.

RESULTS

A total of 524 patients were included, with a participation rate of 93% at 12 weeks. The mean age was 52.79±17.33 years, and the sex ratio M/F was 1.39. At inclusion, the mean IOP was 21.68±9.72mmHg. After 2 weeks of treatment, the mean IOP was 15.49±5.81mmHg, for a reduction of 28.55%. After 12 weeks of treatment, the mean IOP was 13.16±3.54mmHg, for a reduction of 39.30%. The main symptom recorded was a gritty foreign body sensation, the frequency of which was 4.72% at W2 and 2.45% at W12. The main sign was hyperemia (4.33% at W2 and 1.84% at W12).

CONCLUSION

Latanoprost given as first-line monotherapy in POAG in blacks considerably reduces IOP. The incidence of side effects remains low; it is higher at the start of treatment.

Human Gut Microbiota: Toward an Ecology of Disease

Composed of trillions of individual microbes, the human gut microbiota has adapted to the uniquely diverse environments found in the human intestine. Quickly responding to the variances in the ingested food, the microbiota interacts with the host via reciprocal biochemical signaling to coordinate the exchange of nutrients and proper immune function. Host and microbiota function as a unit which guards its balance against invasion by potential pathogens and which undergoes natural selection. Disturbance of the microbiota composition, or dysbiosis, is often associated with human disease, indicating that, while there seems to be no unique optimal composition of the gut microbiota, a balanced community is crucial for human health. Emerging knowledge of the ecology of the microbiota-host synergy will have an impact on how we implement antibiotic treatment in therapeutics and prophylaxis and how we will consider alternative strategies of global remodeling of the microbiota such as fecal transplants. Here we examine the microbiota-human host relationship from the perspective of the microbial community dynamics.
