A rare cause of exophthalmia: Osteoblastoma of the frontal sinus.

Osteoblastoma is a rare benign tumor arising predominantly in the vertebrae or long tubular bones. Its naso-sinusian origin is rare and can be responsible for ophthalmological complications [1]. We report the case of 19-yeaold patient admitted to the Ophthalmology department for progressive right exophthalmia and ptosis evolving over 8 months.

Chronic dissection of the abdominal aorta as a rare complication of Takayasu disease.

Takayasu's arteritis exposes to complications of varying severity, such as arterial stenosis, thrombosis, and more rarely aneurysms. Aortic dissection is a rare complication of Takayasu's disease, reported in few times in the literature, only 7 of which concern the abdominal aorta. We report the case of a 41-year-old woman followed for Takayasu disease for 15 years, who presented an asymptomatic and chronic dissection of the abdominal subrenal aorta.

[The acute respiratory distress syndrome in malaria: is it always the prerogative of Plasmodium falciparum?].

Severe malaria causes nearly one million deaths annually in endemic areas and is a public health priority worldwide. Severity associated with the occurrence of acute respiratory distress syndrome (ARDS) is a well-known complication of infection with Plasmodium falciparum and can reach 25% of infected adults. However, ARDS is less often described with other Plasmodium species.

Barriers encountered using skill-mix to deliver caries prevention in dental practices.

This opinion paper provides an analysis of the barriers and successes experienced when developing and implementing a pilot scheme to deliver caries prevention using skill-mix in the National Health Service (NHS) General Dental Services. A training programme was initiated to develop the skills of extended duties dental nurses to deliver fluoride varnish to patients in selected dental practices in Croydon, London, UK. In the light of the evaluation of this programme, a recommendation is made that similar preventive schemes should be delivered in the future within the NHS dental contract.
