A comparative morphologic and morphometric study about geniculate ganglion development in man and in rat.

Conclusions: Human-rat geniculate ganglion (GG) have multiple origins: (1) An initial proximity (20 μm) to the endocranial foramen of the IAM, suggests neural crest induction; and (2) The influence of epibranchial placodes: the tensor tympani muscle (TTM) and the otic apical coil.

Objectives: This study was undertaken to determine the comparative development of human-rat GG.

Materials And Methods: A light microscopic study of the GG in human material obtained from spontaneous abortions at 9, 13, 14, 17, 18, and 30 weeks, and one neonate was done.

Morphological and morphometric study on human Scarpa ganglion development.

Conclusion: In Scarpa neurons the cell and nuclear area increases and nuclear/cytoplasm ratio decreases with fetal age (p < 0.0001). There are statistically significant differences in cell area between all fetal groups, except for the interval 45-74 mm crown-rump-length (CRL).

Principles of cranial base ossification in humans and rats.

Conclusions: 1. The principle of bilateral symmetry depends on the chordal cartilage that is the keystone in cranial base ossification in rats and humans, due to its anatomical situation and for the production of the chordin protein that regulates the bone morphogenetic protein BMP-7. 2.

Inflammatory myofibroblastic tumor of the temporal bone: a histologically nonmalignant lesion with fatal outcome.

Introduction: Inflammatory myofibroblastic tumor (IMFT) of the temporal bone is an unusual but distinct clinicopathologic entity.

Case Report: We report the case of a 75-year-old patient with an IMFT located in the temporal bone. Symptoms included VI, X, XI, and XII cranial nerves palsies.

[Analysis of the anthropometric, epidemiological, and clinical parameters in patients with snoring and obstructive sleep apnoea].

Objectives: The existence of snoring, apnoeas and diurnal somnolence constitutes obstructive sleep apnoea (OSA), a disease of high prevalence that can cause serious complications. We have made a descriptive study of the epidemiological and clinical characteristics of patients with suspected OSA, with the main target of knowing the value of some of these characteristics in the evaluation of these patients.

Patients And Method: We have had access to a retrospective sample of 433 patients (361 men and 72 women) with an average age of 47 (11.

The predictive value of clinical and epidemiological parameters in the identification of patients with obstructive sleep apnoea (OSA): a clinical prediction algorithm in the evaluation of OSA.

We sought to analyze the predictive value of anthropometric, clinical and epidemiological parameters in the identification of patients with suspected OSA, and their relationship with apnoea/hypopnoea respiratory events during sleep. We studied retrospectively 433 patients with OSA, 361 men (83.37%) and 72 women (16.
