Importance of early and continuous use of protein restriction on the progression of adriamycin nephropathy

Three experimental protocols were carried out with the aim of evaluating the role of protein restriction on the progression of the established adriamycin-induced nephropathy, and whether the protective effect of the diet persists after the diet is discontinued. The effect of a low protein diet (LPD) was studied for 6 weeks in protocol 1, 16 weeks in protocol 2 and for 28 weeks in protocol 3. In protocol 3, one group (LL) received LPD and another (NN) was given a normal protein diet (NPD). A third group (LN) received LPD for 16 weeks and then NPD for 12 weeks and a fourth group (NL) was fed NPD for 16 weeks and then LPD for 12 weeks. In protocol I the tubulo- interstitial index (TILl) of rats on LPD (Md = 2, P25 = 0.0; P75 = 3.5) after six weeks, was smaller than that of the animals on NPD (Md = 6.0; P25 = 3.0; P75 = 8.0; p < 0.05). In protocol 2, the group taking LPD presented an area of interstitial fibrosis (IF) (Md= 0.5%, P25 0.2%; P75 = 1.9%) smaller than that of the NPD group (Md = 6.8%; P25 = 5.2%; P75 = 7.1%; P < 0.05). No significant difference in the area of glomerulosclerosis (GSA) was observed between the animals on LPD (Md = 0.0%; P25 = 0.0%, P75 = 0.0%) and NPD (Md = 0.37%; P25 = 02% P75 = 1.25%; p > 0.05). In protocol 3, the group LL showed GSA (Md = 1.3%; P25 0.6%, P75 = 2.5%) and IF (Md = 3.60/0; P25 = 1.6%; P75 = 5.9%) smaller that those of LN (GSA Md = 10.1%; P25 = 6.6%; P75 = 14.8%; IF; Md = 17.3%; P25 = 14.1%; P75 = 24,5%), NL (GSA: Md = 9.1%; P25 = 5,8%; P75 = 11.7%; IF; Md = 25.0%; P25 = 20.4%; P75 = 30%), and NN (GSA: Md = 6. 75%; P25 = 4.9%; P75 = 11.7%; IF: Md = 20.9%; P25 = 16.2%; P75 = 32.4%). In conclusion, in order to be effective, LPD must be introduced early and maintained for a long period of tune.

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.

Dermatoses bolhosas auto-imunes

Autoimmune bullous dermatoses are diseases in which blisters and vesicles are the primary and fundamental types of skin lesion. Their classification is based on the location of the blister: intraepidermal and subepidermal. Patients produce autoantibodies against self-specific structures of the skin detectable by immunofluorescence techniques, immunoblotting and ELISA. Recent advances in molecular and cellular biology have brought to knowledge these self-antigens, against which patients are sensitized, and which are found in epidermis or in the dermo-epidermal junction. These are low incidence, but high morbidity diseases that may be fatal. The aim of this article is to review and describe the progress of four autoimmune vesiculobullous disorders: endemic pemphigus foliaceous (wild fire), pemphigus vulgaris, bullous pemphigoid and dermatitis herpetiformis. ©2009 by Anais Brasileiros de Dermatologia.

Constipação intestinal

It was reviewed the definition, mechanisms and classification of functional constipation. The diagnostic resources available were showed and it was underlined the importance to investigate and exclude the multiple causes of secondary constipation. The therapy was divided in general measures, like diet and specialized, involving laxatives and others alternatives. It was commented the different categories of laxatives, their actions and adverse effects. It was concluded that the best approach to functional defecatory disorder is biofeedback. Otherwise, for defecatory disturbance caused by mechanical obstruction and refractory constipation due to slow transit the therapeutical option is surgery.

A survey of owner attitudes and experiences in managing diabetic dogs

A survey of the experiences of owners of diabetic dogs was carried out by distributing questionnaires to veterinary clinics in São Paulo, Brazil. A total of 93 dog owners were surveyed over a 4. month period and descriptive statistical analysis, frequency distribution and correlations were performed. In most cases the clinical condition of the dogs had improved following treatment and owners were largely satisfied with veterinary intervention. Injection of neutral protamine hagedorm twice daily was the most commonly prescribed treatment and respondents found this procedure easy to perform, although it did pose some difficulties when the owners were away from their animals. Cost was considered an important factor at the initiation of treatment programs. The information gleaned from this survey, in providing useful insights into the attitudes and experiences of owners of diabetic animals, will contribute to improvements in the treatment and management of such patients. © 2011 Elsevier Ltd.

Gastrointestinal changes associated to heart failure

Over the last decade, several studies were conducted on the gastrointestinal changes associated to chronic heart failure. This article presents a literature review on the physiopathology and clinical consequences of pathological digestive changes of heart failure patients. Structural and functional abnormalities of the gastrointestinal tract, such as edema of absorptive mucosa and intestinal bacterial overgrowth, have been leading to serious clinical consequences. Some of these consequences are cardiac cachexia, systemic inflammatory activation and anemia. These conditions, alone or in combination, may lead to worsening of the pre-existing ventricular dysfunction. Although currently there is no therapy specifically earmarked for gastrointestinal changes associated to heart failure, the understanding of digestive abnormalities is germane for the prevention and management of systemic consequences.

Acompanhamento do aleitamento materno no tratamento de crianças com fenilcetonúria

A fenilcetonúria (PKU) ocorre na incapacidade para transformar fenilalanina em tirosina, trazendo efeitos tóxicos para o sistema nervoso central. Tradicionalmente, no tratamento da PKU, o aleitamento materno é substituído por fórmula láctea. Este estudo verificou os efeitos do aleitamento materno como fonte de fenilalanina no desenvolvimento de crianças com PKU. Participaram dez lactentes com PKU, que iniciaram o tratamento com a introdução de fórmula láctea antes dos 30 dias e que mantiveram o aleitamento materno por no mínimo 30 dias de vida após o início dos procedimentos. Os procedimentos basearam-se em estimar a ingestão de leite materno, com margem segura da concentração da fenilalanina, calculando o volume gástrico e oferecendo inicialmente fórmula láctea, seguida do aleitamento materno em demanda livre, em todas as mamadas. O tempo de amamentação variou de um mês e cinco dias a 14 meses. Os controles sanguíneos foram semanais. Se o nível sérico da fenilalanina estivesse >2 mg/dL e <6 mg/dL mantinha-se a prescrição; se estivesse <2 mg/dL, diminuía-se a fórmula láctea em 25%, aumentando indiretamente o aleitamento materno; se estivesse >6 mg/dL, aumentava-se a fórmula em 50%. Avaliou-se os níveis de fenilalanina, aplicou-se a Early Language Milestone Scale e Passos Básicos do Desenvolvimento. Foram considerados adequados aqueles lactentes que apresentaram índices normativos em todas as avaliações. Dos lactentes, 80% conseguiram manter limites seguros da fenilalanina e desenvolvimento nos índices normativos. Há viabilidade da continuidade do aleitamento materno no tratamento de crianças com PKU desde que os níveis de fenilalanina sejam rigorosamente controlados e que os efeitos do aleitamento materno para o desenvolvimento infantil sejam verificados.

Tolerância ao leite processado em altas temperaturas em pacientes com alergia ao leite de vaca mediada pela imunoglobulina E

INTRODUÇÃO: A incidência de pacientes apresentando alergia à proteína do leite de vaca (APLV) após os 5 anos de idade vem crescendo. Definir se estes pacientes tolerariam a ingestão de alimento produzido com leite processado a altas temperaturas (LPAT) proporcionaria melhor qualidade de vida, definiria melhor prognóstico e possibilitaria avaliar a indicação de dessensibilização com muffin. OBJETIVO: (1) identificar quais pacientes com APLV persistente aos quatro anos poderiam tolerar a ingestão de LPAT, (2) descrever as características clínicas e laboratoriais dos grupos reativo e não reativo ao LPAT, e (3) compara-las entre os dois grupos. MÉTODOS: Estudo transversal, utilizando amostra de conveniência, incluindo todos os pacientes acompanhados no ambulatório de alergia alimentar do Instituto da Criança HCFMUSP que preenchiam os critérios de inclusão e que concordaram em realizar o TPO, entre janeiro/2013 e novembro/2014. Os pacientes foram admitidos em hospital-dia sob supervisão médica e submetidos à ingestão de um muffin contendo 2,8 gramas de proteína do leite de vaca. Foram definidos como tolerantes se não apresentassem nenhuma reação alérgica. Estes pacientes foram submetidos na sequência a novo TPO com leite de vaca in natura para excluir a tolerância ao leite de vaca. RESULTADOS: Foram realizados 38 TPO com LPAT, sendo que 30 pacientes (15 masculinos) preencheram todos os critérios de inclusão. A mediana da idade foi de 7 anos e 7 meses (4a10m -14a2m). 14 pacientes (46%) não apresentaram reação após a ingestão do muffin, sendo considerados como não reativos. A análise comparativa entre os grupos reativos e não reativos ao LPAT, não mostrou diferença estatisticamente significante quanto às características clínicas: idade (p=0,8), sexo (p=0,4), história pessoal de rinite (p=0,7), história pessoal de asma (p=0,7), história pessoal de outras alergias (p=0,6), história familiar de rinite (p=0,7), história familiar de asma (p=0,3), história familiar de outras alergias (p=0,1), relato de anafilaxia prévia (p=0,07), relato de ingestão de traços de leite previamente ao TPO (p=0,4), relato de reação alérgica no último ano antes da provocação (p=0,6), relato de anafilaxia no último ano antes do TPO (p=0,6). Não se observou diferença estatisticamente significante entre os dois grupos para IgE total (p=0,1) e eosinófilos (p=0,6). O teste de puntura para leite de vaca e frações mostrou diferença estatisticamente significante para ?-lactoalbumina (p= 0,01) e para a caseína (p = 0,004); em relação ao ImmunoCAP® apenas para a caseína (p= 0,05) essa diferença foi significante. Ao avaliar estes pacientes 1 ano após o TPO, nenhum dos 16 pacientes que foram reativos ao LPAT estava ingerindo leite de vaca, enquanto 28% dos pacientes que foram tolerantes ao LPAT estavam consumindo leite de vaca in natura sem reação (p=0,037). CONCLUSÃO: O estudo mostrou que os pacientes com APLV desta amostra brasileira apresentaram 2 diferentes fenótipos, sendo que aproximadamente metade tolerou o LPAT. Sendo assim, o TPO para LPAT deve ser considerado para pacientes com APLV, sempre sob supervisão médica e estrutura segura e adequada, pois pode contribuir para uma mudança no paradigma do seguimento destes pacientes. Teste de puntura e ImmunoCAP® para caseína podem sugerir quais pacientes estariam tolerantes ao TPO com LPAT, reforçando dados da literatura internacional

FEEDING AND DIABETES MELLITUS: PERCEPTION AND FOOD CONSUMPTION BY ELDERLY PEOPLE IN THE HINTERLANDS OF PERNAMBUCO

Objective: To evaluate the knowledge of diabetes diet and identify factors that may interfere with the adherence to nutritional therapy and food choices of participants in a Community Center for the Elderly in Sairé, PE. Methods: A quantitative, descriptive and cross-sectional study, which evaluated 39 attendees of that center, from July to August 2014, with or without diabetes mellitus. Two questionnaires were applied to assess socioeconomic data, nutrition knowledge and cultural factors, and check the consumption of food with high and low glycemic index. Data was analyzed using the Assistat Program 7.0 Beta version. Results: The majority of the respondents have knowledge about types of foods that may influence the treatment of diabetes mellitus, as 51.2% (n=20) reported knowing some food that can reduce the risk for diabetes onset or assist in its treatment. Most of the participants reported having acquired such knowledge through the television 35% (n=7) and conversation with peers 35% (n=7). Evaluation of the food intake evidenced higher consumption of foods with high glycemic index. However, among diabetic patients, foods with low glycemic index are consumed more times per week. Conclusion: The knowledge about nutrition and diabetes mellitus was considered adequate, but socioeconomic and cultural factors may interfere in the adherence to diet therapy for diabetes or in the food choices made by the individuals. However, food consumption was considered appropriate among diabetics.
