Abstract: introduction: the treatment of glaucoma is made initially with the use of eyedrops, with the purpose to decrease intraocular pressure and to minimize the damages to the optic nerve. the lack of compliance with drug therapy can be influenced by factors related to patients, doctors and medicines. purposes: to estimate the rate of noncompliance with the treatment with antiglaucoma eyedrops and to verify the intervenience of possible factors for noncompliance. methods: a study of the transversal type was carried out, in the ophthalmologic clinic of the hospital governador israel pinheiro, in belo horizonte, minas gerais. questionnaires were applied to 102 glaucoma patients to collect information about the level of noncompliance and the intervenience of possible factors for noncompliance with drug therapy. results: the rate of noncompliance was 21.5%. the factors: not using the eyedrops due to money shortage (p=0.035) and accomplishment of corrective surgery (p=0.049), significantly contributed to noncompliance. conclusion: more than one fifth of the glaucoma patients does not follow the drug treatment in an adequate way. donation of eyedrops to all the glaucoma patients without favorable economic conditions, governmental actions for the reduction of the prices of the eyedrops, information on the continuity of the use of the eyedrops after the accomplishment of corrective surgeries would help to decrease the rates of noncompliance.

Abstract: glaucoma is defined as an optic neuropathy, characterized for loss of visual field and injury of the optic nerve, being considered as the second cause of blindness in the world, which could be prevented by the use of antiglaucoma eyedrops. the lack of adhesion of the patient to the drug treatment can culminate with loss of the vision. the objective was to revise possible literature data regarding intervening factors for noncompliance and explain estimated rates of noncompliance. a systematic review about the subject was carried out in the period of january to june of 2006. articles had been searched in two data bases, in the national library of medicine (pubmed) and in the literature latin american and caribbean health sciences (lilacs) using the following keywords: glaucoma, compliance of the patient, noncompliance of the patient, treatment and eyedrops. in pubmed, 199 articles were collected, written in english and french languages. no article was found in lilacs. considering the inclusion and exclusion criteria, 27 articles were selected, with 25 originals and two reviews. twelve possible intervening factors for noncompliance were raised, as well as estimates for rates of noncompliance. the noncompliance rates varied from 4.6% up to 59%. two factors, forgetfulness and inadequate between-doses interval, had been associated to noncompliance of the drug therapy. the factors race, adverse effects, treatment cost, number of instilled doses, coexisting illnesses and number of eyedrops used, had resulted contradictory, being impossible to affirm that they have contributed for noncompliance. age, sex, educational level and loss of visual field, had not been associated with noncompliance. the glaucoma patients tended to disregard the drug treatment. the wide variation in noncompliance rates could be an influence from the authors' difficulty to define the noncompliance and the variety of methodologies used to estimate it. more studies are necessary for a better evaluation

Abstract: background: skin changes observed in chronic venous insufficiency have venous reflux as the most common etiology. some authors have reported that reflux in the superficial venous system accounts for 40-60% of leg ulcers in patients with primary varicose veins. objective: to evaluate the correlation between superficial venous reflux and clinical status (ceap classification - clinical, etiology, anatomy and pathophysiology) in patients with primary varicose veins of the lower limbs using duplex scanning. method: a cross-sectional and descriptive study was performed in patients with primary varicose veins. primary variables were venous reflux and clinical status. clinical status was characterized by groups a, b, and c, represented by ceap clinical categories. types of venous reflux in the great and small saphenous veins were used as complementary data, according to engelhorn’s classification (2004). hypotheses of interrelationship between incidence and types of reflux were statistically analyzed using fisher’s exact and chi-square tests. significance was set at 0.05%. results: of 242 lower limbs, 15 were excluded, so that the final sample was comprised of 227 lower limbs. ninety-nine (83.9%) patients were female. mean age was 50 years and median was 49 years. reflux was absent in 93 limbs (41%), and 134 (59%) showed isolated and/or associated reflux. isolated reflux in perforating veins (p = 0.0008) or in association with great saphenous vein reflux (p < 0.0001) was significantly related to clinical status severity. conclusion: duplex scan showed correlation between presence of superficial venous reflux and clinical status severity in patients with primary varicose veins of the lower limbs.

Abstract: OBJETIVO: Desenvolver um modelo experimental estável de aneurisma sacular em carótida de suínos utilizando veia jugular interna. MéTODOS: Em 12 suínos sadios, com peso variando entre 25 e 50kg, cinco machos e sete fêmeas, foi confeccionado aneurisma na artéria carótida comum direita. Após arteriotomia elíptica, foi realizada anastomose terminolateral com coto distal de veia jugular interna. O volume do aneurisma era calculado de maneira que o valor n o excedesse em 27 vezes o valor da área da arteriotomia. Após seis dias, era realizada angiografia e análise microscópica do aneurisma para avaliar perviedade e trombose parcial ou total. RESULTADOS: Houve ganho de peso significante dos suínos no intervalo de tempo entre a confec o do aneurisma e a angiografia (p = 0,04). Foi observada perviedade aneurismática em dez suínos (83%). Ocorreram infec es de feridas operatórias em dois animais (16,6%), ambas com início de aparecimento em três dias após a confec o do aneurisma. Análise histológica dos aneurismas mostrou trombos ocluindo parcialmente a luz em nove suínos (75%). Nesses animais, observou-se que, em média, 9% da luz aneurismática estava preenchida por trombos. CONCLUS O: P de ser desenvolvido um modelo experimental estável de aneurisma sacular em carótida de suínos utilizando veia jugular interna. OBJECTIVE: To develop an experimental model of stable saccular aneurysm in carotid of pigs using the internal jugular vein. METHODS: In 12 healthy pigs, weighing between 25 and 50kg, five males and seven females, we made a right common carotid artery aneurysm. After elliptical arteriotomy, we carried out a terminolateral anastomosis with the distal stump of the internal jugular vein. Aneurysm volume was calculated so that the value did not exceed 27 times the area of the arteriotomy. After six days angiography and microscopic examination were performed to assess patency of the aneurysm and the presence of total or partial thrombosis. RESULTS: There was a significant weight gain of pigs in the time interval between the manufacture of the aneurysm and angiography (p = 0.04). Aneurysmal patency was observed in ten pigs (83%). Operative wound infections occurred in two animals (16.6%), both with early onset, three days after the making of the aneurysm. Histological analysis showed aneurysm thrombus partially occluding the light in nine pigs (75%). In these animals, it was observed that on average 9% of the aneurysmal diameter was filled with thrombi. CONCLUSION: It was possible to develop a stable experimental model of saccular aneurysms in pig carotid artery

Abstract: background and objectives: an inspired oxygen fraction (fio2) of 40% is often used for weaning patients, but lower fio2 values are also recommended, if arterial oxygen pressure (pao2)/ fio2 >150-200 mmhg. this study aimed to compare respiratory variables and vital data values recorded during use of sufficient fio2 (ideal) to maintain peripheral oxygen saturation at 92% with values recorded during use of fio2 established at 40% (baseline) in weaning patients. methods: prospective cross-over study. respiratory variables (respiratory frequency, tidal volume, occlusion pressure, inspiratory time/total time ratio) and vital data (blood pressure and heart rate) were collected sequentially at 30 and 60 minutes with baseline fio2, followed by ideal fio2. these were compared to a generalized linear model for repeated measurements. comparisons between baseline and ideal fio2 values, and arterial blood gases were evaluated by the student's t or wilcoxon tests. results: in 30 adult patients the median of ideal fio2 was 25% (iq25%-75% 23-28). this was significantly lower than baseline fio2 (40%) (p< 0.001). no significant difference was found in the pao2/ fio2 ratio between baseline fio2 (269±53) and ideal fio2 (268±47). tidal volume was significantly lower during use of ideal fio2 (p=0.003) and blood pressure was significantly higher during use of baseline fio2 (p=0.041), but there was no clinical significance. the remaining variables were not affected by reduction in fio2. the ideal fio2 did not influence remaining variables. conclusions: these results suggest that fio2 levels sufficient to ensure a spo2>92% did not alter breathing patterns or trigger clinical changes in weaning patients.
