A status report on human odorant receptors and their allocated agonists.

Olfactory perception begins when odorous substances interact with specialized receptors located on the surface of dedicated sensory neurons. The recognition of smells depends on a complex mechanism involving a combination of interactions between an odorant and a set of odorant receptors (ORs), where molecules are recognized according to a combinatorial activation code of ORs. Although these interactions have been studied for decades, the rules governing this ligand recognition remain poorly understood, and the complete combinatorial code is only known for a handful of odorants.

[The dacryoscanner, an optimal technique for nasolacrimal system exploration].

The dacryoscanner is the imaging technique of choice in case of persistent tearing. It allows the opacification of nasolacrimal system, and thus determines the site and the origin of obstruction. The site could be the lacrimal canaliculus, the lacrimal sac, or the nasolacrimal duct.

Spontaneous resolution of cryptogenic organizing pneumonia in pediatrics: A case report.

Cryptogenic organizing pneumonia (COP) is a rare entity in childhood, particularly in previously healthy children. Moreover, the spontaneous remission of the disease is exceptional. We report on the case of a previously healthy 10-year-old girl who consulted her doctor for a 2-month history of mild pyrexia, fatigue, weight loss, and exertional dyspnea with no response to amoxicillin.

[Immediate hypersensitivity reactions to iodinated contrast agents used in radiology: a review].

The use of iodinated contrast agents (IC) has become common practice nowadays in the daily diagnostic and therapeutic procedures in radiology. Immediate hypersensitivity reactions occurring up to the first hour after injection of IC, can be of serious consequences, occasionally leading to death. This justifies the establishment of a prevention algorithm, including a sharp identification of those at risk and the implementation of premedication with corticosteroids.

Ultrasound as an adjunct to radiography in minor musculoskeletal pediatric trauma.

Purpose: To assess the value of ultrasound as an adjunct to radiography in minor musculoskeletal pediatric trauma.

Methods: Fifty children with 53 suspected fractures were referred for upper and/or lower limbs X-rays, followed by ultrasound. On radiography, we noted presence of fracture, of soft tissue thickening, or absence of any lesion.
