Objective: To evaluate the effects of exposure to emissions from sugar cane burning on inflammatory mechanisms in tissues of the trachea and lung parenchyma in Wistar rats after different periods of exposure. Methods: This was an experimental open randomized study. The animals were divided into four groups: a control group (CG) underwent standard laboratory conditions, and three experimental groups were exposed to emissions from sugar cane burning over different periods of time, in days-1 (EG1), 7 (EG7), and 21 (EG21)...

The combination of tuberculosis with other diseases can affect tuberculosis treatment within populations. In the present study, social network analysis of data retrieved from the Mexican National Epidemiological Surveillance System was used in order to explore associations between the number of contacts and multimorbidity. The node degree was calculated for each individual with tuberculosis and included information from 242 contacts without tuberculosis. Multimorbidity was identified in 49.89% of individuals...

Background: Cardiovascular urgencies are frequent reasons for seeking medical care. Prompt and accurate medical diagnosis is critical to reduce the morbidity and mortality of these conditions. Objective: To evaluate the use of a pocket-size echocardiography in addition to clinical history and physical exam in a tertiary medical emergency care. Methods: One hundred adult patients without known cardiac or lung diseases who sought emergency care with cardiac complaints were included. Patients with ischemic changes in the electrocardiography or fever were excluded...

Amiodarone is a potent anti-arrhythmic drug with a well-known potential chronic pulmonary toxicity. We describe a case of acute pulmonary toxicity (APT) induced by amiodarone in a 57 year old patient submitted to a perfusion of 900 mg in just 6 hours, to control an auricular flutter with rapid ventricular response. During the administration, the patient developed hemodynamic instability and oxygen dessaturation that led to an electrical cardioversion with return of sinus rhythm. Still, the patient continued in progressive respiratory deterioration with acute bilateral infiltrates on chest x-ray and apparent normal cardiac filling pressures confirmed by echocardiography...

We have studied whether hyperbaric oxygen (HBO) prevents different pulmonary aspiration materials-induced lung injury in rats. The experiments were designed in 60 Sprague-Dawley rats, ranging in weight from 250 to 300 g, randomly allotted into one of six groups (n = 10): saline control, Biosorb Energy Plus (BIO), hydrochloric acid (HCl), saline + HBO treated, BIO + HBO treated, and HCl + HBO treated. Saline, BIO, HCl were injected into the lungs in a volume of 2 ml/kg. A total of seven HBO sessions were performed at 2,4 atm 100% oxygen for 90 min at 6-h intervals...

The main puzzle of the pulmonary circulation is how the alveolar spaces remain dry over a wide range of pulmonary vascular pressures and blood flows. Although normal hydrostatic pressure in pulmonary capillaries is probably always below 10 mmHg, well bellow plasma colloid pressure of 25 mmHg, most textbooks state that some fluid filtration through capillary walls does occur, while the increased lymph drainage prevents alveolar fluid accumulation. The lack of a measurable pressure drop along pulmonary capillaries makes the classic description of Starling forces unsuitable to the low pressure, low resistance pulmonary circulation...

UNLABELLED: The hemodialysis (HD) population continues growing and aging, reason why they are required to adapt the human, economic and materials resources to be taken care of. OBJECTIVE: To analyze the distribution of the consultations and the times of admissions in the different Hospital services of which an peripheral arranged HD Center depends. METHOD: We analyzed all the consultations to the Hospital Urgencies Departments and Hospitable admissions of all the patients who received HD in the arranged Center Ponfedial, (sanitary area Ponferrada of 150,000 inhabitants) in period 01/12/02 to the 31/05/05...

Five patients with CF (cystic fibrosis) dead between 1974 to 1982 at ages ranging from one to six months are presented. All of them showed edema, hypoalbuminemia and anemia in a severely compromised clinical situation, and failure to gain weight in spite of being breast-fed in the first weeks of life, in four of them. All of them were second or third degree malnourished babies (Gomez classification) at admission. Five children presented edema, two severe, two moderate and one mild. Hematocrit values ranged from 19% to 39% (means 26...

Lung and heart sections from 33 drug addicts submitted for medico-legal autopsy at the Institute of Forensic Medicine in Copenhagen were studied together with tissue sections from 20 'normal' persons. In the drug addict cases focal bleedings in lung tissue were found in 94%, signs of earlier bleedings, haemosiderin containing histiocytes, were seen in 91%, and focal fibrosis in 46%. The bleeding episodes may be due to hypoxia in connection with heroin intake. In 94% of the drug addicts birefringent material in lung tissue was demonstrated, in 58% in granulomas and giant cells, in 27% in giant cells only and in 9% in isolated histiocytes...
