Community Health Workers and Disease Surveillance in Tanzania: Promoting the Use of Mobile Technologies in Detecting and Reporting Health Events.

This cross-sectional study was conducted in the Kilosa, Morogoro Urban, Ngorongoro, and Ulanga districts of Tanzania to investigate the practices of community health workers (CHWs) related to disease surveillance functions and to establish their needs and technology capacities. We also established the strength of mobile phone networks and internet connections in the study areas to inform the feasibility of using mobile-based applications in community-based disease surveillance. A total of 135 CHWs from 85 villages participated in the study.

Mobile technologies for disease surveillance in humans and animals.

A paper-based disease reporting system has been associated with a number of challenges. These include difficulties to submit hard copies of the disease surveillance forms because of poor road infrastructure, weather conditions or challenging terrain, particularly in the developing countries. The system demands re-entry of the data at data processing and analysis points, thus making it prone to introduction of errors during this process.

Towards one health disease surveillance: the Southern African Centre for Infectious Disease Surveillance approach.

Africa has the highest burden of infectious diseases in the world and yet the least capacity for its risk management. It has therefore become increasingly important to search for 'fit-for- purpose' approaches to infectious disease surveillance and thereby targeted disease control. The fact that the majority of human infectious diseases are originally of animal origin means we have to consider One Health (OH) approaches which require inter-sectoral collaboration for custom-made infectious disease surveillance in the endemic settings of Africa.

Obstructive sleep apnea patients voice analysis.

Unlabelled: It is generally considered that obstructive sleep apnea may associate larynx abnormalities--either anatomic or functional in nature; considering the vocal tract as a series of uniform loss cylindrical pipes the idea of non-invasively exploring this by means of spectral analysis emerged. The aim of our study is to evaluate potential changes in acoustic features of voice in sleep apnea patients as compared to matched controls in order to develop a potential screening test.

Material And Method: Sleep apnea subjects and controls were asked to produce sustained vowels such as "a" and "i" which were recorded and analyzed.

[Pulmonary thromboembolism: specifics of diagnosis in young age--case report].

Pulmonary thrombo-embolism (PTE) is responsible for a reasonable number of undiagnosed pleural effusions. It is considered that PTE causes pleural effusions more frequently than bronchogenic carcinoma although statistics bring it to less than 5% of diagnosed cases. This probably relies in an insufficient investigation of patients with pleural effusion as well as considering PTE a rare cause of disease.
