[Intestinal parasitosis in the inhabitants of a suburban zone in which the groundwater is polluted by nitrates of fecal origin (Yeumbeul, Senegal)]. / Les parasitoses intestinales chez des habitants d'une zone péri-urbaine à nappe phréatique polluée par les nitrates d'origine fécale (Yeumbeul, Sénégal)

This study was carried out in 1997 to 1998, to determine the prevalence of intestinal parasite infestations due to groundwater pollution at Yeumbeul, Senegal, and to follow the progression of parasite infestations following anti-parasite treatment. The study included 705 people living in a suburban zone in which the water table was polluted with nitrates of fecal origin. These individuals consumed either well water or water from springs. The overall prevalence of parasite infestation was 42.26%, but varied significantly with age (p < 0.001). Individuals who consumed well water were more frequently infested than those who consumed spring water, but the difference was not significant (p > 0.3). Giardia and Entamoeba coli were the most frequently isolated parasites, with Giardia predominating in the 0 to 9 year age-group. There was no significant correlation between the prevalence of the various parasites and indicators of water pollution (R2 = 0.0566 for nitrates and 0.1086 for fecal coliform bacteria). Similarly, no correlation was found with water pollution factors such as the depth of the water table (R2 = 0.027) and the distance between the wells and the latrines (R2 = 0.00007). Following specific treatment, the prevalence of parasite infestation fell to 30.81%. This indicates the limitations of drug treatment, which is always used alone to combat intestinal parasites, in the face of possible reinfestation.

[Emergency reimplantation of the tongue after complete traumatic amputation]. / Réimplantation en urgence après amputation traumatique complète de la langue chez un enfant.

Complete traumatic amputation of the tongue is very exceptional, the intra-oral position generally protecting the tongue. Most reported cases of trauma have involved partial section with satisfactory results after simple suture. Complete amputation of a portion of the tongue occurred in a 12-year-old boy during a fight. The fragment of the tongue was brought to the emergency unit. It was placed in heparinated saline solution and replanted successfully three hours after the trauma. Plastic surgery of the oral cavity was also performed to repair laceration injuries. The postoperative period was uneventful and the tongue regained vitality and normal motion. There was just a slight retraction. Replantation of the tongue after complete section may not be successful but should be attempted when possible.
