Multiple hydatid cysts of the neck,the nasopharynx and the skull base revealing cervical vertebral hydatid disease

Hydatid disease is caused by the parasitic tapeworm Echinococcus. This parasite in larval stage can thrive in many parts of the body, most commonly in the liver and the lung. Hydatid disease in the head and neck is uncommon and hydatid cyst presents rarely as a cervical mass. Cervical vertebral echinococcosis is rare. We report a 14-year-old girl with multiple cervical spine hydatid cysts of the C1-C2 vertebrae that spread into the surrounding paravertebral tissues and involve the nasopharynx and the skull base particularly the left jugular foramen. This process has caused a progressive swelling in the left side of the neck located in the retrostyloid compartment of the parapharyngeal space with paralysis of cranial nerves (VI, IX, X, XI, XII). The diagnosis was made based on the image obtained from CT and MRI examinations. Characteristics of this rare disease, diagnosis and treatment difficulty are discussed.     

Pindborg's tumor: a propos of a case

The calcifying epithelial odontogenic tumor was first described as an entity by Danish pathologist Jens Pindborg in 1955. It is an uncommon and locally invasive benign odontogenic tumor. The most characteristic findings are the presence of amyloid-like substance and calcified concentric liesegang rings.     

The optomotor response: a robust first-line visual screening method for mice

In both scotopic and photopic conditions, the rotation of a grating was found to elicit head movements in mice. The highest spatial frequency eliciting this optomotor response provided an estimate of visual acuity. In male C57BL/6J mice, visual acuity increased from 0.26cpd in scotopic conditions to 0.52cpd in photopic conditions whereas it was 0.52 cpd in both sets of conditions in 129/SvPas mice. No optomotor response was detected in albino CD1 mice and rd1 retinal degeneration mice although light sensitivity in CD1 mice was attested by photophobia and normal electroretinograms. This rapid and cheap method could provide a powerful test of visual performance in genetically modified and pharmacologically treated mice.     

Les médecins maghrébins ont-ils besoin de renforcement de leurs capacités en investigation et contrôle des épidémies ?

Objective:

Describe the training needs of young Maghreb doctors in epidemic management.

Methods:

This is a study to quantify the need for medical training on "epidemic management". The study population was formed by residents and assistant professors of the French-speaking faculties of medicine in the Greater Maghreb, hospital-university professors, who were invited to respond to an online questionnaire. The "need" for learning a skill was defined by the perception of its importance, of its low coverage by the curricula and its poor mastery. A grid with 20 items, coded according to the Likert scale of 1 to 5 points, was specially developed for the measurement of need, retained beyond the thresholds of 45/90 points for the two dimensions "confirmation" and "investigation", 60/120 points for the "control" dimension, and 150/300 for the total sum.

Results:

A total of 121 young Maghreb doctors answered the questionnaire to assess the needs for learning epidemic management skills. The median overall scores for the chapters "importance", "coverage" and "performance" were 76, 40 and 48 respectively out of 100 points. The median scores for training «needs» were 54/90, 48/90 and 67/120 points, respectively, for the dimensions «confirmation», «investment» and «control», giving a global median score of 168 / 300.

Conclusion:

Capacity building in epidemic management is a need felt by young Maghreb doctors, partially covered by current medical school programs, and consequently altering their professional performance.
