Estudo da distribuição dos casos de Diabetes Mellitus em Presidente Prudente - SP

The main causes of illness and consequent death in patients affected by Diabetes Mellitus are the long-term complications. Depression can make it harder to control the level of glucose in the blood, as well as intensifying and worsening the clinical complications, thus reducing the quality of life. The aim of this study was to estimate the incidence of Diabetes Mellitus in Public Health Clinic in Presidente Prudente (SP) in patients enrolled in the Hiper-Dia Program. From October 2003 to July 2004, a descriptive survey was carried out. Data were obtained from doctor's records of 50 diabetes patients and also their answers to a specific questionnaire. The majority of the patients were female, had not completed elementary school, with a family income below five minimum wages, a nationally-defined amount related to the poverty line. It was observed that 24% of the patients had depression and 76% never followed a controlled diet. Pharmacological treatment was prescribed for 82% of the patients. Twenty-eight patients were receiving psyicological treatment, together with oral hypoglycemic agents. The glycated hemoglobin was measured in 68%. The association between depression and submission to treatment was not significant. No statistical association was found between the psychologically assisted patient's group and glucose control (p= 0.40), diet control (p= 0.37) and physical activities (p= 0.77). It was concluded that 24% patients had depression and the majority not under diet control, but 82% were under pharmacological treatment.

Bases neurofisiológicas da dependência do tabaco

A maioria dos estudos pré-clínicos e clínicos aponta a nicotina como o principal agente responsável pelo desenvolvimento da dependência ao tabaco. Muitos trabalhos têm demonstrado que as bases neurais da dependência à nicotina são semelhantes àquelas das outras drogas de abuso. A nicotina induz preferência condicionada por lugar e auto-administração e, portanto, atua como reforçador positivo, esse efeito parece ser mediado pelo sistema dopaminérgico mesolímbico. A nicotina também induz à sensibilização comportamental que é provavelmente resultante de alterações da expressão gênica do núcleo acumbens induzidas pela exposição prolongada a essa substância. A suspensão do uso de nicotina resulta em síndrome de abstinência. As evidências indicam que esses sinais e sintomas sejam mediados por receptores colinérgicos nicotínicos centrais e periféricos. Outros neurotransmissores, como por exemplo a serotonina e os peptídeos opióides, também podem estar envolvidos na mediação da dependência e síndrome de abstinência à nicotina. A revisão da literatura mostra a complexidade dos efeitos da nicotina no organismo. A integração entre as abordagens comportamental, neuroquímica e molecular possibilitará a compreensão dos mecanismos neurais da dependência ao tabaco e fornecerá as bases para o desenvolvimento racional de agentes terapêuticos que possam ser utilizados para o tratamento da dependência e síndrome de abstinência ao tabaco.

Inibidores da HIV-integrase: Potencial abordagem farmacológica para tratamento da AIDS

AIDS has the HIV as its etiological agent. Researches has been done to find new pharmacological agents to be used in therapy, because of problems of resistance and side effects. The HIV-integrase inhibitors are some of those new agents that are being studied. This updating focusses on the fundamental information about HIV and HIV-integrase and the main methods being used to develop these new drugs, with examples for each case.

Síndrome das pernas inquietas: Diagnóstico e tratamento. Opinião de especialistas Brasileiros

This article contains the conclusions of the November 17-18, 2006 meeting of the Brazilian Study Group of Restless Legs Syndrome (GBE-SPI) about diagnosis and management of restless legs syndrome (RLS). RLS is characterized by abnormal sensations mostly but not exclusively in the legs which worsen in the evening and are improved by motion of the affected body part. Its diagnosis is solely based on clinical findings. Therapeutic agents with efficacy supported by Class I studies are dopamine agonists, levodopa and gabapentine. Class II studies support the use of slow release valproic acid, clonazepan and oxycodone. The GBE-SPI recommendations for management of SPI are sleep hygiene, withdrawal of medications capable of worsening the condition, treatment of comorbidities and pharmacological agents. The first choice agents are dopaminergic drugs, second choice are gabapentine or oxycodone, and the third choice are clonazepan or slow release valproic acid.

Terapia do diabetes mellitus em cães

Diabetes Mellitus is caracterized by a disturbance on endocrine pâncreas with reduction in serum levels of insulin. The deficiency or absence of insulin promotes alterations in the metabolism of carbohydrates, lipidis and proteins. The most common clinical signs of disease are polyuria, polydipsia, polyphagia and loses of weight. The diagnosis is made based on clinical symptoms, with laboratory confirmation through persistent hyperglycemia on fasting and glycosuria. Treatment includes insulin therapy, diet, exercise and oral hypoglycemic agents in an attempt to reverse the catabolic effects associated with deficiency or antagonism of insulin and restore normal homeostasis of the metabolism of proteins, lipids and carbohydrates

Oral health education in schools: promoting health agents

Purpose: The aim of this study was to verify the influence of preschool children participating in an oral health education programme on daily health practices of their families, through parent's perception. Methods: A sample of 119 parents of 5- to 6-year-old preschool children were selected. Data were collected using a structured open-closed questionnaire, self-administered. The questions focused on parents' knowledge about activities of oral health education conducted in school, the importance given by them to these activities, learning from their offspring and the presence of habit change at home. Results: In total, 63 (52.9%) parents agreed to participate. Ninety-eight per cent knew about educative and preventive activities developed at school and all of them affirmed that these activities were important, mainly because of knowledge, motivation and improvement in children's health. Ninety and half per cent of parents reported that they learned something about oral health from their children and, among these, almost half (47.8%) cited toothbrushing as the indicator for better learning. Besides this, 87.3% of participants revealed the change in oral health habits of their family members. Conclusion: Preschool children were able to transmit knowledge acquired at school to their parents that included change in oral health routine of their family members.

Influence of dental exposure to oral environment on smear layer removal and collagen exhibition after using different conditioning agents

Although in vitro studies have shown encouraging results for root surface conditioning with demineralizing agents, in vivo studies have failed to show its benefits in periodontal healing. This can be attributed to several factors, among which, the hypermineralization of dental surface. Therefore, this in vitro study compared, using scanning electron microscopy (SEM), the effect of root surface conditioning with different conditioners (1% and 25% citric acid, 24% EDTA and 50 mg/mL tetracycline hydrochloride) in impacted teeth and in teeth that had their roots exposed to the oral environment. One trained examiner assessed the SEM micrographs using a root surface modification index. There was a tendency of more root surface modification in the group of impacted teeth, suggesting that the degree of root mineralization influences its chemical demineralization.

Anthelmintic efficacy of oral trichlorfon solution against ivermectin resistant nematode strains in cattle

Infected calves from two different rural estates in Brazil were studied to assess the anthelmintic efficacy of oral trichlorfon against naturally occurring ivermectin resistant parasitic nematode strains. In experiment 1, infected animals were from a region where ivermectin resistant populations of Haemoncus placei, Cooperia punctata,Cooperia spatulata and Trichuris discolor have recently been identified. Six calves with natural gastrointestinal nematode infections were treated with 48.5 mg/kg aqueous trichlorfon administered orally and six calves acted as a non-treated control group. In experiment 11 24 naturally infected calves were selected to enter one of four treatment groups, six animals each received: 48.5 mg/kg oral trichlorfon; 200 mu g/kg subcutaneous 1% ivermectin; 630 mu g/kg subcutaneous 3.15% ivermectin; or no treatment (control group). Gastrointestinal helminths were counted and identified post-mortem at 7 days (trichlorfon and 1% ivermectin treated and untreated animals) or 14 days (3.15% ivermectin treated and untreated animals) after administration of the test agents. Experiment I identified a high level efficacy for oral trichlorfon against four helminth species that have previously been shown to be ivermectin resistant in this geographical region: percentage efficacy was 99.82% against adult H. placei, 99.18% against C. punctata, 99.33% against C. spatulata, 81.06% against T. axei, 98.46% against Oesophagostomum radiatum and 100% against T. discolor. Trichlorfon also showed activity against the ivermectin (1% and 3.15%) resistant helminth species identified in experiment 11, attaining efficacy levels of 99.17% against H. placei, 98.46% against C punctata and 100.00% against T. discolor. These findings indicate that oral trichlorfon is an effective treatment option in the management of cattle infected with ivermectin resistant helminths. (C) 2009 Elsevier B.V. All rights reserved.
