RESUMO

Objective: To investigate the respiratory and postural adaptations associated with mouth and nasal breathing and to evaluate the associations of such adaptations in mouth breathers' self-perceived quality of life. Method: Cross-sectional study with mouth breathers (initial n=116 and final n=48) and nasal breathers (initial n=131 and final n=24) from elementary school, aged between 7 and 14 years. Chest expansion, using cirtometry, the breathing pattern and the use of accessory muscles, by means of clinical evaluations and photogrammetry, and flexibility tests were evaluated in both groups. Subsequently, the mouth breathers were asked to complete the quality of life questionnaire. Statistical tests: Chi-square, odds ratio, Mann-Whitney, and binomial tests were first applied followed by logistic regressions. Results: Thoracic breathing (p=0.04), using of accessory muscles (p=0.03) and reductions in flexibility (p=0.001) increased the chances of an individual being a mouth breather when compared to nasal breathers. Subsequently, using of accessory muscles decreased the chances of snoring among mouth breathers (p=0.03); the presence of shoulder asymmetry reduced the chances of experiencing quiet sleep (p=0.05) and increased the chances of coughing or being tired when playing or running (p=0.008). Finally, forward head position reduced the chances of waking up at night (p=0.04) and experiencing shortness of breath (p=0.05). Conclusions: Respiratory and postural adaptations increased the chances of individuals persisting with mouth breathing. Additionally, these adaptations could be associated with mouth breathers' self-perceived quality of life. .

RESUMO

Se realiza la presentación de un caso de anencefalia asociado a cíclope que ocurrió en la misión realizada recientemente en el hermano pueblo de Haití, y en la que se obtuvo un feto muerto de 1 850 g con fusión de los 2 ojos y esbozo de nariz en forma de trompa, achatada. Se hace la discusión y revisión de la literatura al respecto

RESUMO

In the central nervous system, magnesium ion (Mg2+) acts as an endogenous modulator of N-methyl-D-aspartate (NMDA)-coupled calcium channels, and may play a major role in the pathomechanisms of ischemic brain damage. In the present study, we investigated the effects of magnesium chloride (MgCl2, 2.5, 5.0 or 7.5 mmol/kg), either alone or in combination with diazepam (DZ), on ischemia-induced hippocampal cell death. Male Wistar rats (250-300 g) were subjected to transient forebrain ischemia for 15 min using the 4-vessel occlusion model. MgCl2 was applied systemically (sc) in single (1x, 2 h post-ischemia) or multiple doses (4x, 1, 2, 24 and 48 h post-ischemia). DZ was always given twice, at 1 and 2 h post-ischemia. Thus, ischemia-subjected rats were assigned to one of the following treatments: vehicle (0.1 ml/kg, N = 34), DZ (10 mg/kg, N = 24), MgCl2 (2.5 mmol/kg, N = 10), MgCl2 (5.0 mmol/kg, N = 17), MgCl2 (7.5 mmol/kg, N = 9) or MgCl2 (5 mmol/kg) + DZ (10 mg/kg, N = 14). Seven days after ischemia the brains were analyzed histologically. Fifteen minutes of ischemia caused massive pyramidal cell loss in the subiculum (90.3 percent) and CA1 (88.4 percent) sectors of the hippocampus, vehicle vs sham). Compared to the vehicle-treated group, all pharmacological treatments failed to attenuate the ischemia-induced death of both subiculum (lesion: 86.7-93.4 percent) and CA1 (lesion: 85.5-91.2 percent) pyramidal cells. Both DZ alone and DZ + MgCl2 reduced rectal temperature significantly. No animaldeath was observed after drug treatment. These data indicate that exogenous magnesium, when administered systemically post-ischemia even in different multiple dose schedules, alone or with diazepam, is not useful against the histopathological effects of transient global cerebral ischemia in rats

RESUMO

Se presenta la experiencia con 14 casos de holoprosencefalia diagnosticado prenatalmente por ultrasonografía. Esta serie demuestra que esta malformación se asocia frecuentemente con anomalías cromosómicas, principalmente trisomía 13, y casi invariablemente con un mal pronóstico perinatal

RESUMO

A estimulaçäo repetida sublimiar experimental de áreas límbicas leva ao desenvolvimento de convulsöes generalizadas, inclusive motoras e permanentes, fenômeno conhecido como kindling. De outro lado a estimulaçäo acústica de animais sensíveis pode induzir convulsöes tônico-clônicas generalizadas, conhecidas como convulsöes audiogênicas (CA). A repetiçäo de CA pode recrutar áreas prosencefálicas, modelo conhecido como kindling audiogênico. Nas CA agudas, o colículo inferior é a área inferior mais crítica envolvida na origem de atividade epileptiforme, enquanto que no kindling audiogênico, a amígdala e o córtex cerebral podem ser recrutados. A evoluçäo comportamental indicativa desse recrutamento foi avaliada mediante o uso de técnicas neuroetológicas
