Tracheotomy in children: evolution in indications.

OBJECTIVES: To evaluate the evolution of indications for tracheostomy in children. METHODS: A retrospective review of 46 children undergoing tracheostomy between 1996 and 2001. RESULTS: The indications for tracheostomy were classified in two groups:(1) prolonged ventilator dependence (57%), (2) upper airway obstructions (43%). The average age of the tracheostomy was 3 years and 8 months. This was higher in the first group (5.5 years). Decannulation was accomplished in 52%. The indications for tracheostomy were evaluated and were found to decrease in frequency for upper airway obstructions. An increasing indication was for chronic disorders requiring prolonged ventilator dependence. Complications occurred in 50% of children. Overall mortality was 13-2.7% directly related to the tracheostomy. CONCLUSIONS: Evolving indication has been ventilator dependence. Upper airway obstruction as an indication has diminished in frequency, especially with the concomitant progress of endoscopic techniques.

[Imported malaria in Tunisia].

Thanks to the national programme of malaria eradication carried out between 1968 and 1972, there has been no active transmission of the parasitosis in Tunisia since the last indigenous case in 1979. Since 1980, with the increase in international exchanges especially with sub-Saharian countries, only imported cases of malaria have been reported in Tunisia. A retrospective and thorough survey of malaria cases diagnosed in the laboratory of parasitology of the Pasteur Institute in Tunis from 1980 to 1995 determined the epidemiological characteristics of this imported parasitosis. All in all, during the sixteen years following eradication, 245 cases were registered. The majority of cases (86.2%) was diagnosed by a systematic control of groups at risk within the national programme of malaria eradication. The remaining 13.8% cases sought medical advice when clinical symptoms appeared after their return from endemic countries. The population most affected by imported malaria were men (sex-ratio: 6.8) aged between 20 and 40 years (76% of cases); 38% were Tunisians having sojourned in an endemic country, essentially students from sub-Saharian Africa. The presumed country of contamination was African in 92.7% of the cases. Entrance into Tunisia by patients was mainly by air; 4% of the registered cases had come by land from Algeria. Sound knowledge of the epidemiological characteristics of imported malaria would make for a better follow-up of the affected population and thus reduce the probability of repeated transmission.
