Severe Acute Pancreatitis Associated with Weil's Disease.

Leptospirosis is an emerging zoonosis of worldwide importance. Its distribution is closely linked to hydrometric conditions. It is characterized by a wide clinical range, from the subclinical form, or one with few symptoms; which resolves spontaneously, to the multi-visceral form, known as icterrohemorrhagic disease or Weil's disease, with a lethal risk.

Seroprevalence of hepatitis E virus among blood donors in eastern Algeria.

Hepatitis E virus (HEV) is recognized worldwide as the leading cause of orofecal-transmitted hepatitis. However, blood transmission has been increasingly implicated in recent years raising health concerns. In Algeria, updated prevalence data are lacking.

Air Pollution and Health Risk: Intelligent Mapping.

Air pollution by chemical or bacteriological pollutants is not limited to a geographical area at the discrete border. Also, factors taken into account in the risk analysis such as patient age, seasons, socio-economic background or race are far from being necessary as discrete values. Often used analysis tools are limited to statistical analyzes.

Epidemiological and Clinical Factors Associated with Spontaneous Clearance of Hepatitis C Virus.

BACKGROUND The risk of chronicity is high after acute hepatitis C. The infection remains limited and spontaneously resolves in an average of 30% of subjects. Such subjects are considered recovered and do not require any medical care.

First study of hepatitis delta virus in Algeria: Seroprevalence and risk factors in Setif region (east of Algeria).

Background: No recent data are available on hepatitis delta virus (HDV) prevalence in Algeria. For this reason we conducted an epidemiological study, cross-sectional seroprevalence of HDV in the region of Setif.

Methods: Between 2011 and 2014, sera samples of 500 patients (carrying HBsAg) admitted to the Division of Infectious Diseases Teaching Hospital, Setif (east of Algeria), were tested for anti-HDV-IgG ab (ETI-AB-DeltaK-2).
