ABSTRACT
The histochemical effects of the lethal concentration that kills 50% of larvae (LC50) of three biological agents, abamectin, Bacillus thuringiensis and spinosad on the carbohydrates (polysaccharides), proteins, nucleic acids and lipids content of the midgut and fat bodies of Culex pipiens 2nd instar larvae were studied. The results showed that the three tested compounds reduced the carbohydrates (polysaccharides), proteins, RNA synthesis and lipids content after 72 hours of treatment where abamectin was the most effective followed by Bacillus thuringiensis then spinosad.

UNLABELLED: Vascular tumors of the sinus cavities are rarely documented in the literature. They are characterized by a histological diversity. They can be benign or malignant. The most common histologic type is the hemangioma. Their management is not well codified, it benefited from advances in modern imaging and endoscopic surgery. The objective of the work is to study anatomical and clinical characteristics, therapeutic and outcome. PATIENTS AND METHODS: The observations of 10 vascular tumors of the nasal cavities collected between January 2009 and July 2011 were studied retrospectively. The management of these tumors was based on nasal endoscopy, imaging, biopsy, and some angiography for embolization. The epidemiological parameters, histopathological, clinical, therapeutic and outcome were studied. RESULTS: The average age was 25.4 years, male was marked with a sex ratio of 4. Epistaxis was the revealing sign. All tumors were benign, with a predominance of the hemangioma (4 cases), followed by angiofibroma of the septum (3 cases) and nasopharyngeal angiofibroma (3 cases). All patients were operated, by endonasal technique in 7 cas/10 and transfacial road in 3 cases. Embolization was performed in 5 patients, there were two hemangiomas and 3 nasopharyngeal fibromas. No case of recurrence has been noted so far. CONCLUSION: The vascular tumors of the nasal cavities are difficult to treat, especially when they reach a large volume and at an extension to adjacent areas, which makes the surgical procedure difficult and bloody. The use of selective embolization in these cases is required.

Necrotizing fasciitis is an exceptional and severe form of subcutaneous gangrene which requires early diagnosis and emergency treatment. We report the case of a 24 year old woman presenting with necrotizing fasciitis after pansinusitis resistant to treatment. The germ detected was pseudomonas aeruginosa. The infection was controled with intensive care, antibiotics and surgical resection of necrotic tissues. The aim of this observation is to highlight the clinical characteristics of this disease, and to insist on the necessity to recognize the early symptoms and to start treatment as soon as possible.

Apert syndrome is a type of acrocephalosyndactylia that belongs to the group of craniofacial synostoses. It is characterised by craniofacial dysmorphia and syndactyly of hands and feet. It is an uncommon affection that is often transmitted through an autosomal dominant mode, but sporadic cases are frequent. We report the case of a 2 months old baby brought by his parents to the paediatric emergencies for respiratory distress occurring within the framework of a polymalformative syndrome. The examination showed brachycephaly, bilateral exorbitism, syndactyly of the hands and feet and an anal fistula. Echocardiographic examination showed a cardiovascular malformation (interventricular communication), the whole suggestive of Apert syndrome. The child was admitted in intensive care during five days. He died following a respiratory infection. Through this observation the authors illustrate the clinical and evolutionary aspects as well as the therapeutic difficulties of this affection.
