PURPOSE: To evaluate the behavior of the scotopic Oscillatory Potentials (OP) of total field electroretinogram (ERG) in hypertensive retinopathy. METHODS: Forty-four patients (n=44) were submitted to clinical evaluation and subdivided in to 2 groups: hypertensives (HT) and normotensives (NT). The hypertensives patients were maintained under placebo during the period of the study. Soon afterwards, they were submitted to ophthalmological evaluation and accomplishment of ERG. Total field electroretinogram (ERG), with recording of the answers: scotopic, maximum scotopic, OP scotopic, photopic and flicker.For analysis of the OP answer the latency of the first 2 peaks and the average value of the width of the first 3 peaks of the compound of 3 consecutive answers, denominated Oscillatory Index (OI) were considered. RESULTS: The sample was composed of 44 patients, with a mean age of 51.55 ± 7.2 range (34 to 68) years, 24 being females. Arterial hypertension affected 26 (59.1%) of the patients, while 18 (40.9%) were normotensives. The average of the obtained IO was 257.41 µv in the NT group and of 217.81 µv in HT (p=0.006). The averages of latencies obtained for peaks 1 (NT-18.42 and HT-17.91) and 2 (NT-24.54 and HT - 24.29) were not different between the groups (p>0.05). CONCLUSIONS: The hypertensive patients presented significantly smaller oscillatory index than the normotensives, suggesting that arterial hypertension might cause dysfunction of the internal retina.

In recent decades, Brazil has undergone several political, economic, social and cultural changes that showed changes in quality of life, especially regarding health. The main diseases affecting the Brazilians no longer became acute and chronic non-transmitted diseases. The modification of nutritional habits accompanied that change, greatly influencing the Brazilians’ diet. The dissemination of propaganda by the Brazilian media and modern labor activities stimulates the consumption of foods high in fats, sugars and carbohydrates, contributing to the increase in the percentage of overweight and obese individuals in the world. According to the Ministry of Health the overweight’s Brazilian population percentage increased from 42.7% to 48.1% in five years. It is considered that Body Mass Index (BMI) between 25.0 and 29.9 means overweight. Studies in Applied Behavior Analysis to the Health emphasizes techniques, especially focused on increasing the rate of adherence to treatment. On the Nutritional area, these techniques help to identify the environmental variables under which feeding behavior is under control. The emphasis on self-observation and self-description provide the analysis and research of control variables by the individual himself. Thus, the present study aimed to evaluate the effectiveness of the presentation of justifications, in the form of a printed manual, on report of adherence to nutritional instructions in overweight adults, as well as observing the maintenance of this report through follow-up. Participated in this sample, nine individuals enrolled in the Multiprofessional Project of Patients with Nutritional Disorders, attended in the Hospital Universitário Bettina Ferro de Souza (HUBFS) of the Universidade Federal do Pará (UFPA). These participants were divided into three study conditions: Condition 1 (weekly monitoring with application of a manual containing justifications for the following nutritional rules), Condition 2 (weekly application with accompaniments 24-hours recall), Condition 3 (inquiry the medical records of patients with unique monitoring by the HUBFS’ nutrition service. Have been associated anthropometric data, body fat percentage and body folds to the Index of Reporting of Adherence (IRA). Results showed that there was no difference in the indexes of Adherence Reports obtained by participants of Condition 1 and condition 2. However, we observed an increase in the IRA after intervention (compared with values observed in baseline) and reduction in monitoring, regardless of the condition to which the participant was exposed. Thus, the rates of reported adherence did not depend specifically on how the allegations were presented, which were in written form and orally.

Life quality assessment of patients after phacoemulsification or extracapsular cataract extraction
(2014-02) MENDONÇA, Paula Teixeira de; MENDONÇA, Leonardo Teixeira de; ROSA, Alexandre Antonio Marques; SILVEIRA, Luiz Carlos de Lima
Purpose: To study the quality of life, treatment outcomes, and satisfaction in patients who have undergone cataract surgery Methods: This comparative case series study was conducted at the Ophthalmology Service of the Bettina Ferro de Souza University Hospital, Belém, Pará, Brazil. Totally, 60 patients with cataract were included; 50% underwent conventional extracapsular cataract extraction (ECEE) and 50% underwent cataract extraction by phacoemulsification (PHACO). Patients were interviewed using the Visual Function 14 (VF-14) questionnaire to determine the quality of life before and 30 days after surgery. The results of ophthalmological examination were recorded in the patients' files and were available throughout this study. One-way ANOVA, Tukey's post-hoc comparison, and the sign test were used for statistical analyses. Results: The mean VF-14 satisfaction index was 38.0 and 89.4 before and after surgery, respectively, for the ECEE group and 47.0 and 94.1, respectively, for the PHACO group. The improvement in patient quality of life after surgery was significant in both groups (p<0.0001), with a similar amount of improvement in both groups. Conclusions: The observed improvement in quality of life was significant (p<0.0001) and directly related to patient satisfaction with surgical outcomes, which was also significant (p<0.0001) as assessed using the VF-14. Satisfaction and quality of life are individual factors; consequently, patient responses to questions regarding improvements in the ability to perform each activity are subjective and depend uniquely on individual perception.

Prevalência de hipertensão arterial em pacientes com oclusão do ramo da veia central da retina

PURPOSE: To identify in patients with branch retinal vein occlusion using ambulatory blood pressure monitoring and clinical blood pressure measures: hypertension prevalence, and nocturnal profile of blood pressure. METHODS: Prospectively, 93 eyes of 83 patients with branch retinal vein occlusion were submitted to ophthalmological examination. Afterwards the patients were submitted to clinical evaluation and blood pressure monitoring. Non-dipper was defined as a fall in systolic blood pressure < 10%, and dipper when this value was higher. RESULTS: Disease affected one eye in 73 (88%) patients. The temporal superior branch was the site of occlusion in 61 (65.6%) eyes, while in the others the infero-temporal branch was affected. Seventy six (92%) patients were diagnosed as hypertensive after clinical evaluation. Ambulatory blood pressure monitoring identified 76 hipertensives, 5 normotensives, 1 white-coat hypertensive and one masked hypertensive subjects. The two latter were excluded from the analysis. Of the 81 analyzed patients, forty (49%) were dippers and 41 (51%) were non-dippers. Among the HT (n=76), 36 (47%) were dippers and 40 (53%) were non-dippers. CONCLUSION: Prevalence of hypertension in our series was extremely high (92%) which suggests that physiopathology of the disease has a close relationship with changes promoted by hypertension. A little more than half of the hypertensives were non-dippers (n=40; 52,6%). These evidences suggest that a 24-hour sustained level of blood pressure may be an additional risk factor for branch retinal vein occlusion.
