Results: The analysis showed that the patients mean age was 48 years-old, with the age peak prevalence was from 60 to 69 years-old, with male predominance of 2:1. The undifferentiated non-keratinized squamous cell carcinoma was predominant in 23 samples (79%), differentiated non-keratinized squamous cell carcinoma was found in 4 samples (13.3%) and keratinized squamous cell carcinoma was found in 3 samples (10%). The laminin expression, which is nor...

Initially this narrowest part of nasal airway was considered an isolated deformity; subsequently the congenital Stenosis of pyriform aperture was thought to represent a microform of holoprosencephaly. In this report a male neonate had respiratory distress, cyclic cyanosis and apnea after delivery. The patient underwent surgical correction of pyriform stenosis by sublabial access. In the follow up, the patient had good evolution. The report of this deformity shows an important cause of neonatal nasal obstruction and its differential diagnosis with bilateral choanal atresia. Congenital stenosis of nasal pyriform aperture can be surgically corrected when necessary.

É provocada pelo crescimento excessivo do processo nasal medial da maxila causando um estreitamento do terço anterior da fossa nasal. Inicialmente foi relatada uma deformidade isolada, posteriormente a estenose congênita da abertura piriforme foi considerada como apresentação de forma menor da holoprosencefalia. Neste artigo relatamos um caso de recémnascido do sexo masculino que apresentava desde o parto dispnéia, cianose e episódios de apnéia. O paciente foi submetido a cirurgia com alargamento da abertura piriforme por acesso sublabial. No seguimento apresentou boa evolução durante o acompanhamento. O relato desta deformidade mostra sua importância como causa de obstrução nasal congênita e diagnóstico diferencial de atresia coanal. A estenose congênita da abertura piriforme pode ser reparada adequadamente, quando necessário, através de procedimento cirúrgico.

It can affect the anterior and/or posterior plates, with or without hitting the nasofrontal duct. It has a large potential of complications and its management still being a controversy. To present the casuistic of fractures frontal sinus, the epidemiology and clinical and surgical management of frontal sinus fractures. Not randomized retrospective study of 24 patients with frontal sinus fractures Hospital of Clinics, School of Medicine Botucatu, São Paulo, Brazil. From the 24 patients, we had 16 (66,6%) fractures of the extern plate and 8 (33,4%) of both. In 2 patients the nasofrontal duct was involved. Others facial fractures were associated in 20 (83,4%) cases and major lesions of the cerebral segment were found in 13 (54,2%). Subpalpebral incision was performed in the majority with satisfactory aesthetic results. The basis of the surgical treatment was reduction and fixation with different materials (steel...

Methods: One hundred and twenty rats, that had an average weight of 100g, were used. They received water and a standard diet with 20% protein during 7 days for adaptation to the diet itself and to environmental conditions. After that period, the animals were randomly distributed in two groups of 60 rats each: Group 1 -the animals received a control diet with 20% casein for 21 days; Group 2 -hypoprotein diet with 2% casein for 21 days. After the adaptation period, 12 animals of each group were sacrificed at 5 moments: the beginning of experimental period (M0), 4° day (M1), 7° day (M2), 14° day (M3) and 21° day (M4). The diet to the other rats was maintained until the last sacrifice. The following variables were evaluated: body weight, blood albumin rate, tissue's hydroxyproline, hydroxyproline/total protein ratio and rupture strength in the intestinal wall of the ileum and the distal colon. Results: It was observed that the rupture strength in the ileum segment and distal colon was lower in malnourished animals (Group 2); the loss of mechanical resistance was higher in the distal colon segment than in the ileum probably due to the smaller concentration of tissue collagen in the distal colon. Conclusion: Protein malnutrition induces the loss of mechanical resistance of the ileum and distal colon and may be associated with a smaller percentage of collagenous tissue formation in the intestinal wall.
