Cyclical pattern of non-nutritive sucking in normal and high-risk neonates.

This study determined patterns of suction cycles by recording sucking pressure in full-term infants, normal pre-term infants and newborns with pathology (hypoxia at birth). Associations between these patterns and some clinical parameters were established in order to evaluate feeding capacity for the purpose of guiding specific stimulation and aiding hospital discharge in better health conditions. Seventy-five infants of both sexes were assessed after informed consent, grouped by their status at birth.

Human temporomandibular joint disc: anatomy and measurements in prenatal development.

The objective of this study was to determine morphological characteristics and measurements of the temporomandibular joint (TMJ) disc in human fetuses between 16 and 20 weeks of intrauterine life, and correlate it with oral-facial neuro-muscular maturing. Scanner images were used to record the length of the disc (D) and the thickness of its anterior middle and posterior bands in TMJ anteroposterior vertical sections from human fetuses of 16, 18 and 20 weeks of intrauterine life (WIL). Mean disc length was 1.

Parotid sialosis: morphometrical analysis of the glandular parenchyme and stroma among diabetic and alcoholic patients.

Background: Among the agents that cause parotid sialosis, diabetes mellitus type 2 and chronic alcoholism are included. In this study, the morphometrical modifications in the diabetic parotid sialosis were determined to compare them with the histopathological characteristics of alcoholic parotid sialosis.

Methods: Five parotid biopsy samples obtained from patients with diabetic sialosis, 12 samples from patients with alcoholic sialosis and seven from individuals without these pathologies (control group) were analyzed.

Morphometric analysis of the parotid gland affected by alcoholic sialosis.

Background: In alcoholic parotid sialosis, the gland is frequently enlarged due to ductal and/or acinar hypertrophy, ductal hyperplasy and stromal fat infiltration. The aim of this study was to determine acinar and ductal dimensions, the number of striated ducts and the proportion of fat tissue in patients with and without alcoholic parotid sialosis.

Methods: Twelve parotid biopsy samples from patients with hepatic alcoholic cirrhosis and those from seven controls were used.

Structural and functional salivary disorders in type 2 diabetic patients.

Unlabelled: Diabetes mellitus type 2 is the most common metabolic disorder and it causes an important morbimortality. The structural modifications in the parotid gland (sialosis) had already been described in these patients and could result in variations in the salivary composition, as well as an increase in periodontal and dental pathology.

Objectives: To compare the biochemical findings in the saliva and to correlate these biochemical disturbances with the morphologic findings previously described.

Structural differences between alcoholic and diabetic parotid sialosis.

Unlabelled: Between the sialosis' etiologic agents, we can find the chronic alcoholism and diabetes. Both nosologic entities are described using a similar histopathologic pattern.

Objectives: The purpose of this work has been analyzing and comparing the histopathological differences between the diabetic and alcoholic sialosis.

Alcoholic parotid sialosis: a structural and ultrastructural study.

Objectives: The purpose of this study is to demonstrate the histopathological differences between the initial and advanced stages of Alcoholic Sialosis, a pathology that generally involves parotid hypertrophy and structurally affects, to diverse degrees, the other salivary glands.

Study Design: An analysis and comparison was carried out of the structural and ultrastructural modifications of the parotid glands from the hepatic biopsies of chronic alcoholics with clinical diagnosis of cirrhosis and from autopsies on individuals who had died from alcoholic hepatic cirrhosis. Various samples of normal gland obtained from surgical material were used as a control.
