Anatomical Study of the Digastric Muscle: Variations in the Anterior Belly
Provedor de dados: 77
Autores: Liquidate,Bianca Maria; Barros,Mirna Duarte; Alves,Adriana Leal; Pereira,Celina Siqueira Barbosa.
The digastric muscle is formed by two muscle bellies: one anterior and one posterior, joined by an intermediate tendon. It is localized in the anterior cervical region. The anterior belly divides the region between the hyoid bone and the mandible into two: laterally the submandibular triangle, and medially the submental triangle. The anatomical variations described in the literature relate to the anterior belly and consist of differences in shape and muscle attachment. This cross-sectional cohort study had the objective of describing anatomical variations in the anterior belly of the digastric muscle. The neck regions of 10 cadavers of male adults were dissected in the Department of Morphology, between June 2004 and June 2006. The digastric muscles that...

Study on the Morphology and Frequency of the Vomeronasal Organ in Humans
Provedor de dados: 77
Autores: Carvalho,Maria de Fátima Pereira de; Alves,Adriana Leal; Barros,Mirna Duarte.
The vomeronasal organ was first described in humans in the seventeenth century. It has a chemosensory function and is found in the mucosa of the nasal septum of mammals and consists of an opening in the mucosa at the base of the nasal septum. For this study, 143 individulas undergoing nasofibrolaryngoscopy were studied, and presence of the vomeronasal organ was considered to be a finding from the examination. Three morphological types of vomeronasal organ were observed: fissure, fossette and circular. The total prevalence of the vomeronasal organ among these patients was 28% (40 individulas ). The prevalence of the vomeronasal organ in this study population is compatible with what has been reported in other studies. The forms of the vomeronasal organ can...

Cardia: at the End of the Day, what is it?
Provedor de dados: 77
Autores: Fregnani,José HumbertoTavares Guerreiro; Macea,José Rafael; Barros,Mirna Duarte; Liquidato,Bianca Maria; Macea,Maria Inez Marcondes; Alves,Adriana Leal; Pereira,Celina Siqueira Barbosa; Pinto,Antonio Cardoso; Carvalho,Maria de Fátima Pereira de; Carillo,Joáo.
There is no consensus about the precise definition of what the cardia is. Although this term is often utilized in the medical literature, it takes on a variety of meanings, depending on the context. For histologists and endoscopists, the cardia is a region of the stomach immediately below the gastroesophageal junction. However, the concepts of gastroesophageal junction used by histologists and endoscopists are not the same as used by anatomists. This junction is histologically defined as the abrupt transition from the nonkeratinized stratified squamous epithelium of the esophagus to simple columnar epithelium and corresponds to the endoscopically defined Z-line. Nevertheless, this epithelial change does not occur exactly in the anatomical transition...

Minor Salivary Glands Morphology in Xerostomia Patients
Provedor de dados: 77
Autores: Liquidato,Bianca Maria; Barros,Mirna Duarte; Filho,Ivo Bussoloti; Pereira,Celina Siqueira Barbosa; Macéa,Maria Inêz Marcondes.
The minor salivary glands are found scattered throughout the oral mucosa, especially in the lips and soft palate mucosa. Several factors can cause xerostomia, whereas the salivary glands histological characteristics are also considered as factors for defining the etiology. Thus, the minor salivary glands biopsy represents an essential tool for attending the required diagnosis criterion in the classification of Sjögren's Syndrome patients, since it does not present risk for the patient. The objective of this study is to determine the histological description of the minor salivary glands obtained from the biopsies of xerostomia patients and to classify the minor salivary gland histological aspect as the Sjögren's Syndrome. Forty laminas of xerostomia...

Estrogen Receptors in Immunohistochemically Stained Slides: Comparing Subjective and Computerized Evaluation Methods
Provedor de dados: 77
Autores: Millas,Ieda; Barros,Mirna Duarte; Curcio,Daniella Franco; Buck,Hudson Sousa; Liquidato,Bianca Maria.
Immunohistochemistry is a specific and sensitive staining method for detection of several proteins. One important function of this method is to help us on the diagnosis of the presence of specific receptors as the estrogen receptors. The aim of this study was to compare two different methods to evaluate immunohistochemical staining intensity to detect the presence of ER in the nasal mucosa tissue: one using a digital system and the other through conventional direct microscopy observation. Sixty two stained samples were observed and analyzed under optic microscopy by three specialized professionals, who have graded intensity from: absent, mild, moderate and intense staining. Afterwards, an objective measurement was obtained by a relative optical density...

Benign Inclusions in Lymph Nodes
Provedor de dados: 77
Autores: Spinardi,Julia Regazzini; Goncalves,Isis  Rocha Dias; La Falce,Thiago Souza; Fregnani,José Humberto Tavares Guerreiro; Barros,Mirna Duarte; Macea,José Rafael.
Benign inclusions are foci of non-neoplastic ectopic tissue in lymph nodes. They are classified into three types: epithelial, nevomelanocytic and decidual. It is important to identify them for the differential diagnosis with lymph node metastases, particularly among patients who present proliferative benign lesions. In general, epithelial inclusions are presented inside lymph nodes as epithelial cysts or as numerous structures resembling ducts. The cells of these structures may originate from the cells of paramesonephricus ducts, salivary glands, breast tissue, thyroid follicles, squamous epithelium or mesothelium. Paramesonephricus -type inclusions are almost exclusively found in pelvic lymph nodes and, in appearance, they resemble the epithelium of the...
