Alcohol consumption and maxillofacial fractures in times of Covid-19: a cross-sectional study in a cuban university hospital / Consumo de alcohol y fracturas maxilofaciales en tiempos de Covid-19: un estudio transversal en un hospital universitario cubano

Introduction: The consumption of alcoholic beverages reduces the body's ability to deal with dangerous situations and exposes people to trauma. Objective: To determine the association between the consumption of alcoholic beverages and the characteristics of maxillofacial fractures treated at a Cuban university hospital in the context of COVID-19. Material and Methods: An observational, analytical, and cross-sectional study was carried out in the Maxillofacial Surgery unit at the "Carlos Manuel de Céspedes" General University Hospital during the year 2020. Prevalence ratios, 95% confidence intervals and p-values were obtained using generalized linear models. Results: In 58.23% of the cases, fractures were related to the consumption of alcoholic beverages. The fundamental etiology was interpersonal violence (47.75%), regardless of the consumption of alcoholic beverages. There was a prevalence of patients with nasal fractures (n=98; 55.06%), among which, 35.71% had consumed alcoholic beverages at the time of the trauma. Being male (p=0.005), the lack of university studies (p=0.007), the need for surgical treatment (p<0.001), the fractures of the zygomaticomaxillary complex (p=0.023), and the traumas that occurred during the weekends (p<0.001) or during the month of June (p=0.029) were factors associated with a higher frequency of fractures related to the consumption of alcoholic beverages. There was a lower frequency of fractures associated with alcohol consumption during the months of January (p=0.006) and March (p=0.001). Conclusion: Six out of ten cases were under the influence of alcoholic beverages. There was a greater number of young and male patients, mainly due to interpersonal violence.

Introducción: La ingestión de bebidas alcohólicas disminuye la capacidad del organismo para enfrentar situaciones de peligro y lo predispone a sufrir traumatismos diversos. Objetivo: Determinar la asociación entre el consumo de bebidas alcohólicas y las características de las fracturas maxilofaciales atendidas en un hospital universitario cubano en el contexto de la COVID-19. Material y Métodos: Estudio observacional, analítico y transversal realizado en el servicio de Cirugía Maxilofacial del Hospital General Universitario "Carlos Manuel de Céspedes" durante el 2020. Se obtuvieron razones de prevalencia, intervalos de confianza a 95% y valores p mediante modelos lineales generalizados. Resultados: En el 58.23% de los casos las fracturas se relacionaron con la ingestión de bebidas alcohólicas. La etiología fundamental fue la violencia interpersonal (47.75%), independientemente del consumo o no de bebidas alcohólicas. Predominaron los pacientes con fracturas nasales (n=98; 55.06%), en los que el 35.71% había consumido bebidas alcohólicas en el momento del trauma. El sexo masculino (p=0.005), la carencia de estudios universitarios (p=0.007), la necesidad de tratamiento quirúrgico (p<0.001), las fracturas del complejo cigomático-maxilar (p=0.023), los traumas sucedidos durante los fines de semanas (p<0.001) o durante el mes de junio (p=0.029) fueron factores asociados a una mayor frecuencia de fracturas relacionadas con el consumo de bebidas alcohólicas. Hubo menor frecuencia de fracturas asociadas a este consumo durante los meses de enero (p=0.006) y marzo (p= 0.001). Conclusión: Seis de cada diez casos estuvieron bajo los efectos de la ingestión de bebidas alcohólicas. Existió una mayor afectación de pacientes jóvenes, masculinos, a causa principalmente de la violencia interpersonal.

Effect of chronic ingestion of wine on the glycemic, lipid and body weight homeostasis in mice / Efeito da ingestão crônica de vinho sobre a homeostase glicêmica, lipídica e ponderal em camundongos

ABSTRACT Background: The health benefits associated with moderate wine consumption, as with ethanol and phenolic compounds, include different mechanisms still little understandable. Aim: Evaluate glycemic and weight variations, and the deposit of triglycerides, cholesterol and liver glycogen with red wine consumption. Methods: 60 ApoE knockout mice were divided into three groups of 20: Wine Group (WG), Ethanol Group (EG) and Water Group (WAG). They received daily: WG 50 ml of wine and 50 ml water; EG 6 ml ethanol and WAG 94 ml of water. All groups were followed for four months. The food intake was monitored daily, in the period from eight to ten hours and held every five days. The measurement of water intake was also made every five days. The weighing of the animals took place every ten days. Results: The WG had higher weight increase as compared to the other groups. The concentration of hepatic triglyceride was higher in WG (57%) and the EG group was lower (31.6%, p<0.01) than the control. The concentration of cholesterol was lower in the WG (23.6%), as well as EG (24.5%, p<0.05). The concentration of glycogen was higher in WG (16%) and fasting blood glucose was higher in EG compared to the other groups but not both demonstrated a statistically significant difference. Conclusion: The WG increased triglyceride and WAG decreased cholesterol. The triglyceride may be increased due to the high caloric value of wine or some unknown property that led to significant increase in subcutaneous andretroperitoneal fat in mice.

RESUMO Racional: Os benefícios para a saúde associados ao consumo moderado de vinho, como etanol e compostos fenólicos, incluem mecanismos diferentes ainda pouco compreensíveis. Objetivo: Avaliar as variações da glicemia, peso e depósito de triglicrideos, colesterol e glicogênio hepático com o uso de vinho tinto. Métodos: Sessenta camundongos ApoE knockout foram divididos em três grupos de 20: Grupo do Vinho (WG), grupo do Etanol (EG) Grupo Água (WAG). Cada grupo recebeu diariamente: WG 50 ml de vinho e 50 ml de água; EG 6 ml de etanol e WAG 94 ml de água. Resultados: O WG teve aumento de peso mais elevado em comparação com os outros grupos. A concentração de triglicerídeos foi maior no WG (57%) e no grupo EG inferior (31,6%) do que no controle (p <0,01). A concentração de colesterol foi inferior no WG (23,6%) e no EG (24,5%, p<0,05). A concentração de glicogênio foi maior no WG (16%); a glicemia capilar foi maior no EG em comparação com os outros grupos, mas não demonstrou diferença estatisticamente significativa. Conclusão: Triglicerídeos ficaram aumentados no WG e o colesterol diminuiu no WAG. Os triglicerídeos podem ter aumentado devido ao alto valor calórico do vinho ou alguma propriedade desconhecida que levou ao aumento significativo da gordura subcutânea e retroperitoneal nos camundongos.

Tuberculose pulmonar: associação entre extensão de lesão pulmonar residual e alteração da função pulmonar / Pulmonary tuberculosis: association between extent of the residual pulmonary lesion and alteration in the lung function

OBJETIVO: Descrever as alterações nas variáveis da espirometria e seus distúrbios; estudar a existência de associação entre a extensão da lesão pulmonar residual ao final do tratamento da tuberculose e a alteração da função pulmonar aferida pela espirometria. MÉTODOS: Estudou-se uma série de 96 pacientes com diagnóstico de tuberculose pulmonar, atendidos em três unidades de saúde de Região Metropolitana do Recife, durante o período de janeiro de 2003 a novembro de 2005. Foram analisados pacientes de ambos os sexos, com idade a partir de 15 anos, cujas radiografias do tórax do final do tratamento foram classificadas pelo critério da National Tuberculosis Association (NTA). Os pacientes responderam questionário, no início da pesquisa, e foram submetidos à prova de função pulmonar, após o término do tratamento. RESULTADOS: Dos 96 pacientes estudados, concluímos que 89,6 por cento apresentavam seqüelas radiográficas; 54 por cento apresentavam seqüelas moderadas a graves. Estas alterações radiográficas correspondiam a 24,6 por cento e 73,8 por cento, respectivamente, de alterações na função pulmonar. CONCLUSÃO: Foram identificadas 89,6 por cento de lesões residuais radiográficas, enquanto 66,7 por cento das disfunções respiratórias alertam para o fato de que a assistência ao paciente com tuberculose pulmonar não deve se restringir apenas à cura baciloscópica da doença. A identificação de lesões pulmonares residuais e disfunções respiratórias em pacientes que concluem o tratamento da tuberculose permitirão instituir medidas precoces de tratamento dessas seqüelas para uma melhor qualidade de vida.

OBJECTIVE: To describe alterations in spirometric variables and its disturbances and to study the existence of a relationship between extent of the residual lung lesion at the end of treatment for tuberculosis and alteration of the lung function measured by spirometry. METHODS: Analyzed were 96 patients with diagnosis of pulmonary tuberculosis, treated in three health centers in the metropolitan area of Recife, from January, 2003 to November, 2005. Patients of both genders, 15 years of age or older were included, whose chest x-rays at end of the treatment were classified according to criteria of the National Tuberculosis Association (NTA) for extent of lung lesion. Patients replied to a questionnaire at the beginning of the survey, and were submitted to spirometry after conclusion of treatment. RESULTS: Of the 96 patients, 89.6 percent presented with radiographic sequels. About 54 percent had moderate to severe sequels. These radiographic alterations correspond to 24.6 percent and 73.8 percent respectively of alterations in the pulmonary function. CONCLUSION: The large number of residual radiographic lesionss (89.6 percent) and breathing dysfunction (66,7 percent) identified in this survey call attention to the fact that treatment of a patient with pulmonary tuberculosis must not be restricted to bacteriological healing of the disease. Identification of the residual lung lesions and of the breathing dysfunction in patients who conclude treatment will promote early actions to treat these sequels, improving the quality of life of these patients.

Prevalencia de bebedores de alcohol entre los pacientes que se atienden en la Facultad de Odontología / Prevalence of alcohol drinkers among patients of the Odontology School

La odontología debería tener mayor ingerencia en algunos problemas de salud pública general importantes en nuestro país. De acuerdo a este se realizó un estudio para determinar la prevalencia de bebedores problema en quienes acudían a recibir atención dental a la Facultad de Odontología de la Universidad de Chile en 1989. Se analizaron 420 pacientes mayores de 15 años de ambos sexos, cuyas edades fluctuaron entre los 15 y los 74 años. La investigación se realizó como un estudio transversal, por medio de la aplicación de un instrumento ya probado para tal efecto: la Escala Breve de Bebedores Alcohólicos, E.B.B.A. De la muestra seleccionada se estudiaron tres variables: sexo, edad y distribución por clínica, las que fueron analizadas estadísticamente mediante el test de Chi cuadrado y la prueba de Z. Los resultados obtenidos a partir de la muestra indican que hay una alta prevalencia de bebedores problema, habiéndose obtenido una tasa global de 31,9 por ciento de ellos. La diferencia de frecuencia encontrada entre ambos sexos fue estadísticamente significativa. La información obtenida permite sugerir la necesidad de profundizar los conocimientos en cuanto a los cambios morfofuncionales de las estructuras bucomáxilo faciales en pacientes adictos al alcohol
