Case-control study of drinking water quality in Yemen.

Background: Water, sanitation and hygiene (WASH) activities collapsed in Yemen due to the 2015 war, causing acute safe water shortage, poor sanitation and hygiene, and degraded microbial water quality. The cholera outbreaks in 2016/2017 triggered emergency WASH interventions to improve water quality and reduce cholera and other water-borne disease incidence.

Aim: This study aimed to assess the microbial water quality in Sana'a, Yemen, following cessation of the WASH activities.

Groundwater salinization risk assessment using combined artificial intelligence models.

Assessing the risk of groundwater contamination is of crucial importance for the management of water resources, particularly in arid regions such as Menzel Habib (south-eastern Tunisia). The aim of this research is to create and validate artificial intelligence models based on the original DRASTIC vulnerability methodology to explain groundwater salinization risk (GSR). To this end, several algorithms, such as artificial neural networks (ANN), support vector regression (SVR), and multiple linear regression (MLR), were applied to the Menzel Habib aquifer system.

Elephantiasis Nostras Verrucosa of the Lower Limb: A Case Report and Literature Review.

Elephantiasis nostras verrucosa (ENV) is a rare complication of chronic lymphedema, leading to progressive cutaneous hypertrophy and disfigured lower extremities. We present an unusual case of a 79-year-old man with ENV, who had an episode of erysipelas treated and cured with antibiotics. The patient presented with progressive painless lymphedema of the lower limb years ago, complicated with skin changes.

The thoracobrachial outlet syndrome, a false negative on MRI is possible: About a case.

The diagnosis of thoracobrachial outlet syndrome is one of the most discussed diagnoses. We report the case of a 33-year-old woman who presented to the consultation for pain, edema, and paresis of the left upper limb. Magnetic resonance imaging makes it possible to make the diagnosis, but it happens in certain situations that it reveals certain limits for the confirmation of this syndrome.

Migration of guiding catheter during placement of hemodialysis femoral catheter: case report.

Migration of guiding catheter during placement of hemodialysis femoral catheter is an unusual, early and rare mechanical complication. We report here the case of a 70-year-old man, admitted for severe renal failure, uremic syndrome and hyperkalemia, requiring an extra renal purification session which was complicated by a blockage of the femoral venous catheter guide during its removal. Such a complication highlights the importance of good anatomical knowledge, good monitoring by an experienced person during central venous catheterization, and the interest in using ultrasound guidance before and after catheter placement.
