Genetic diversity in global populations of the critically endangered addax () and its implications for conservation.

Threatened species are frequently patchily distributed across small wild populations, ex situ populations managed with varying levels of intensity and reintroduced populations. Best practice advocates for integrated management across in situ and ex situ populations. Wild addax () now number fewer than 100 individuals, yet 1000 of addax remain in ex situ populations, which can provide addax for reintroductions, as has been the case in Tunisia since the mid-1980s.

[Neonatal caecal perforation revealing congenital megacolon].

Spontaneous intestinal perforations are rare in a full term new-born. We report the case of an infant born at 41 weeks' gestation who, three days after birth, had pneumoperitoneum revealing congenital megacolon. Surgical exploration showed diastatic perforation of the cecum associated with a disparity in rectosigmoid caliber.

[Primary pseudotumoral calcinosis in children].

Pseudotumoral calcinosis is a relatively rare benign tumor, characterized by calcium deposition in peri-articular soft tissues. We here report the case of a 15-year old boy with primary tumoral calcinosis of the left hip as well as a literature review. The patient underwent total mass resection.

[Lipoblastoma detected in older children: an unusual case and literature review].

Lipoblastoma is a relatively rare benign tumor. It derives from embryonic white fat cells. It almost exclusively affects children less than 3 years of age.

Forecast analysis of the incidence of tuberculosis in the province of Quebec.

Background: While the overall population prevalence of tuberculosis in Quebec has been declining for many years, tuberculosis is still disproportionately more prevalent among the immigrant and Inuit communities. As such, the aim of this study was to forecast the incidence of tuberculosis in the Province of Quebec over time in order to examine the possible impact of future preventative and treatment programs geared to reducing such disparities.

Methods: A compartmental differential equation based on a Susceptible Exposed Latent Infectious Recovered (SELIR) model was simulated using the Euler method using Visual Basic for Applications in Excel.

A Palaearctic migratory raptor species tracks shifting prey availability within its wintering range in the Sahel.

Mid-winter movements of up to several hundreds of kilometres are typical for many migratory bird species wintering in Africa. Unpredictable temporary food concentrations are thought to result in random movements of such birds, whereas resightings and recoveries of marked birds suggest some degree of site fidelity. Only detailed (e.

Tuberculosis in quebec: a review of trends.

Unlabelled: The aim of this research was to conduct a thorough review on the literature of tuberculosis in Canada and the Province of Quebec. To achieve this aim, an exhaustive literature review of tuberculosis in the Province of Quebec was undertaken. Data was collected with the goal of creating an epidemiological and public health evidence base to forecast the spread of tuberculosis.
