Iran J Pediatr; Vol 24 (No 4), Aug 2014 Published by: Tehran University of Medical Sciences (http://ijp.tums.ac.ir) Fig.1: Left. NeuN-immunonegative neurons in a pontine histological section of a SIDS victim dead at 2 months. Right. NeuN_immunopositivity in an equivalent section of a control case (late fetal death -38 gestational weeks) for comparison NeuN immunostaining. Magnification: 40× chemical breathing-depended components of blood and cerebrospinal fluid (e.g. pO2, pCO2, pH). The pathological involvement of the vagalglossopharingeal neuronal circuitry explains some lethal reflexogenic mechanism, quoted in the literature as “drive”, “death-feigning” and/or “Ondina’s course” reflexes. Moreover, parahypoglossal glossopharingeal brainstem damage can promote suffocation by tongue hypotonia during supine sleep, especially if an abnormal reticular formation 4 impairs respiration and/or gastro-esophageal reflux goes into trachea. Overall the results obtained in the 12 cases of sudden death reported here, in agreement with those highlighted in our previous study[2] performed on a very large survey of perinatal deaths (140 SIDS, 95 SIUDS and 78 controls), show the common congenital origin of SIUDS and SIDS and support the statement of the National Institute of Child Health and Human Development: “SIDS is a developmental disorder. It takes its origin from fetal development”. In the world, only Italy has a national law that orders “Regulations for Diagnostic Post Mortem Investigation in Victims of the SIDS and Unexpected Fetal Death”. This law can be an example for the other nations in the world, and we believe it should be known. The present paper is the first result of the application of the law. The province of Trento (North Italy) applies this law because it is an autonomous province. The use of NeuN immunohistochemistry is another new important marker in the study of this pathology.

To cite: Arora A, Donald PM. BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016216797 DESCRIPTION Odontomas are benign neoplasms of odontogenic origin. They are more appropriately termed hamartomas because of their limited growth potential rather than true neoplasm. Clinically, three types of odontomas are identified in the literature: central (intraosseous) odo...

An Unusual Association of Odontomas with Primary Teeth

Odontomas generally appear as small, solitary or multiple radio-opaque lesions found on routine radiographic examinations. Traditionally, odontomas have been classified as benign odontogenic tumors and are subdivided into complex or compound odontomas morphologically. Compound odontomas commonly occur in the incisor-canine region of the maxilla and complex odontomas are frequently located in th...

An Attached Odontoma to the Roots of a Mandibular Molar Tooth: A Case Report

Introduction: Odontomas are the most common odontogenic tumors. These lesions are usually considered a hamartoma than a neoplasm. Unlike normal tooth morphology, tissue arrangement is irregular in these lesions. Odontoma has self-limiting and slow growth, and if left untreated, its size will not increase over time. Most of these lesions are clinically asymptomatic and are detected on routine ra...
