Neoplasia papilar cística do pâncreas

Papyllary cystic tumor of the pancreas, so-called Frantz’s tumor, is rare. Clinical presentation of this disease is usually a slowly growing abdominal mass with or without abdominal pain, affecting predominantly young females. Its pathogenesis is still unknown . Surgical resection is usually curative, and prognosis is excellent. The authors report two pancreatic tumor cases(Frantz’s tumor) in women aged 26 and 31 years old. Pre operative assessment showed a solid-cystic tumor of the tail and body of the pancreas. An extended distal pancreatectomy was performed without splenic preservation

Repercussões do tempo operatório em pulmões de ratos idosos

A duração das operações pode representar um fator importante para uma série de complicações pós-operatórias, especialmente para os indivíduos idosos. Objetivo: estudar a repercussão nos pulmões, de operações de diferentes tempos de duração. Métodos: Vinte ratos idosos (18 meses) e 20 jovens (3 meses) foram separados aleatoriamente em grupos A e B respectivamente. Os grupos foram divididos em A1, A2, A3, A4, B1, B2, B3 and B4, com cinco ratos cada. Os animais foram anestesiados com pentobarbital (20mg/Kg) intraperitoneal. No subgrupo A1 e B1 foi feita operação com duração de 30 minutos, nos grupos A2 and B2 60 minutos, em A3 and B3 a operação foi feita em 120 minuto e os animais A4 e B4 (controle) não foram operados. O procedimento consistiu de laparotomia xifopubiana que foi aberta e fechada tantas vezes quanto necessário para atingir os tempos estipulados. Após o quinto dia pós-operatório os animais foram mortos com superdose de anestésico e biópsias de ambos os pulmões foram realizadas. Os achados histopatológicos foram transformados em escores. Resultados: os grupos de ratos jovens atingiram os escores: A1= escore 6, A2=11; A3=28; A4=5. Os ratos idosos tiveram os escores: B1=12; B2=34; B3=51 e B4=6. A análise estatística revelou diferenças significantes entre os escores dos grupos A e B. Conclusões: O tempo prolongado nas operações realizadas em ratos idosos contribuiu para o aparecimento de alterações pulmonares de modo significante. Quanto maior o tempo operatório, mais intensas e mais freqüentes as complicações pulmonares

Comparison of prophylactic and therapeutic use of short-chain fatty acid enemas in diversion colitis: a study in Wistar rats

OBJECTIVES: To study the effect of short-chain fatty-acids on atrophy and inflammation of excluded colonic segments before and after the development of diversion colitis. INTRODUCTION: Diversion colitis is a chronic inflammatory process affecting the dysfunctional colon, possibly evolving with mucous and blood discharge. The most favored hypotheses to explain its development is short-chain fatty-acid deficiency in the colon lumen. METHODS: Wistar rats were submitted to colostomy with distal colon exclusion. Two control groups (A1 and B1) received rectally administered physiological saline, whereas two experimental groups (A2 and B2) received rectally administered short-chain fatty-acids. The A groups were prophylactically treated (5th to 40th days postoperatively), whereas the B groups were therapeutically treated (after post-operative day 40). The mucosal thickness of the excluded colon was measured histologically. The inflammatory reaction of the mucosal lamina propria and the lymphoid tissue response were quantified through established scores. RESULTS: There was a significant thickness recovery of the colonic mucosa in group B2 animals (p = 0.0001), which also exhibited a significant reduction in the number of eosinophilic polymorphonuclear cells in the lamina propria (p = 0.0126) and in the intestinal lumen (p = 0.0256). Group A2 showed no mucosal thickness recovery and significant increases in the numbers of lymphocytes (p = 0.0006) and eosinophilic polymorphonuclear cells in the lamina propria of the mucosa (p = 0.0022). CONCLUSION: Therapeutic use of short-chain fatty-acids significantly reduced eosinophilic polymorphonuclear cell numbers in the intestinal wall and in the colonic lumen; it also reversed the atrophy of the colonic mucosa. Prophylactic use did not impede the development of mucosal atrophy

Integridade da pele em idosos: revisão da literatura segundo as cartas de promoção da saúde

Trata-se de uma revisão bibliográfica que objetivou relacionar as medidas educativas para a promoção da integridade da pele em idosos com as Cartas de Promoção da Saúde.

Cuidado de enfermagem ao potencial doador de órgãos em morte encefálica: uma reflexão sobre a prática

Despite of the technological advances that favor the transplant process, there are issues of effectiveness of care necessary for the maintenance of potential organ donors with brain death, which contribute to the no realization of transplants of organs and tissues of these patients. It is presupposed that the problems could be related to perceptions and understandings that the professionals of the units of internment have about the care required by the diagnosis of brain death. The aim of this study was to understand the meaning of the nursing care of the potential organ donor with brain death to the nursing staff. Descriptive study with qualitative approach guided by Action Science Theory and the critic-reflexive research methodology accomplished with five nurses and 19 nursing technicians from Operative Rehabilitation Center in a public hospital at Natal / RN, Brazil, between March and May 2013. Data were collected through semi-structured interviews with individual reflection about the care and through group interview, after approval by the Ethics and Research Committee, CAAE No.: 04255612.7.0000.5537. The analysis was performed in a thematic way according to Bardin. During the group meeting the participants were driven in a discussion about the need for change and how to perform them. The results indicate that the professionals actions are consistent with those required for maintenance of potential organ donors, although the material and human resources are not adequate. That situation leads the professionals to develop a meaning of care as one labor more, demanding more than they can give. They express beliefs and feelings concerning the hope that their care brings a greater good that is to save lives. The reflection for a possible change of action was difficult to accomplish due to professionals not to be able to self evaluate, what lead to direct your changes suggestions for other team members. It is concluded that the care provided to these patients is a difficult care, evidenced by suffering both death situation of the person cared and pain of their families, as the dehumanizing conditions of work, helping themselves to keep distance from patients to not suffer so much. The knowledge impregnated in their act, are scientific, ethical, aesthetic and personal kind with a predominance of the scientific followed by the personal. The study was also relevant to the practice of nursing in maintaining the potential donor, in that it allowed the identification of the knowledge used by nurses in their care practice and the meaning understanding of the professionals on the care provided, as a good action that brings satisfaction when the transplanting is executed. Other experiences are suggested with the critic-reflexive research methodology, both in research as in teaching nursing

Efeitos da perda de peso induzida pela cirurgia bariátrica sobre a função respiratória

Background: Obesity leads to alteration of lung volumes and capacities due to accumulation of fat in the chest wall and abdomen. Few studies have shown that weight loss induced by surgery improves lung function. Our objective was to evaluate the anthropometric development, pulmonary function, respiratory muscle, strength and endurance after weight loss induced by bariatric surgery. Methods: We evaluated in pre and post operative period variables of weight, BMI, NC, WHR and spirometric and respiratory pressure. Results: 39 subjects were evaluated, with age mean 35.9 ± 10.9 years, predominantly by women (76.3%). The weight mean decreased from 124.8 ± 17.5 kg to 88.8 ± 14.28 kg in post operative. The mean BMI ranged from 47,9 ± 5,6 Kg/m² to 34,3 ± 4,75 Kg/m². There was a significant increase in FVC from 3,63 ± 0,94 to 4,01±1,03, FEV1 from 3,03 ± 0,72 to 3,39 ± 0,85, FEF 25-75% from 3,41 ± 0,72 to 3,82 ± 0,94, PEF from 6,56 ± 1,47 to 7,81 ± 1,69, ERV from 0,35 ± 0,39 to 0,66 ± 0,38, MVV ranged from 103,43 ± 22,21 to 137,27 ± 29,84, all of them to p<0,01. The MIP and MEP showed no significant difference in pre and post operative. It was noted that for every centimeter reduced in neck circumference, an increase of 0.06 in FVC and 5.98 in MVV is observed. This is also observed in weight and BMI. Conclusion: We conclude that weight loss induced by bariatric surgery in obese provides a significant improvement in lung function and reduction of fat around the neck is more important in the generation of lung volume than the reduction of BMI

Revisitando o eletrocorticograma intra-operatório na epilepsia mesial do lobo temporal: relevância das oscilações de alta frequência

Epilepsies are neurological disorders characterized by recurrent and spontaneous seizures due to an abnormal electric activity in a brain network. The mesial temporal lobe epilepsy (MTLE) is the most prevalent type of epilepsy in adulthood, and it occurs frequently in association with hippocampal sclerosis. Unfortunately, not all patients benefit from pharmacological treatment (drug-resistant patients), and therefore become candidates for surgery, a procedure of high complexity and cost. Nowadays, the most common surgery is the anterior temporal lobectomy with selective amygdalohippocampectomy, a procedure standardized by anatomical markers. However, part of patients still present seizure after the procedure. Then, to increase the efficiency of this kind of procedure, it is fundamental to know the epileptic human brain in order to create new tools for auxiliary an individualized surgery procedure. The aim of this work was to identify and quantify the occurrence of epilepticform activity -such as interictal spikes (IS) and high frequency oscillations (HFO) - in electrocorticographic (ECoG) signals acutely recorded during the surgery procedure in drug-resistant patients with MTLE. The ECoG recording (32 channels at sample rate of 1 kHz) was performed in the surface of temporal lobe in three moments: without any cortical resection, after anterior temporal lobectomy and after amygdalohippocampectomy (mean duration of each record: 10 min; N = 17 patients; ethic approval #1038/03 in Research Ethic Committee of Federal University of São Paulo). The occurrence of IS and HFO was quantified automatically by MATLAB routines and validated manually. The events rate (number of events/channels) in each recording time was correlated with seizure control outcome. In 8 hours and 40 minutes of record, we identified 36,858 IS and 1.756 HFO. We observed that seizure-free outcome patients had more HFO rate before the resection than non-seizure free, however do not differentiate in relation of frequency, morphology and distribution of IS. The HFO rate in the first record was better than IS rate on prediction of seizure-free patients (IS: AUC = 57%, Sens = 70%, Spec = 71% vs HFO: AUC = 77%, Sens = 100%, Spec = 70%). We observed the same for the difference of the rate of pre and post-resection (IS: AUC = 54%, Sens = 60%, Spec = 71%; vs HFO: AUC = 84%, Sens = 100%, Spec = 80%). In this case, the algorithm identifies all seizure-free patients (N = 7) with two false positives. To conclude, we observed that the IS and HFO can be found in intra-operative ECoG record, despite the anesthesia and the short time of record. The possibility to classify the patients before any cortical resection suggest that ECoG can be important to decide the use of adjuvant pharmacological treatment or to change for tailored resection procedure. The mechanism responsible for this effect is still unknown, thus more studies are necessary to clarify the processes related to it

Avaliacão da satisfação do usuário e da qualidade dos tratamentos endodônticos em Centros de Especialidades Odontológicas da Grande Natal-RN

Objective: To evaluate the degree of users satisfaction and technical quality of endodontic treatment in specialized dental clinics (CEO) of Grande Natal / RN between 2006 and 2008. Methodology: evaluated 282 endodontically treated teeth in CEOs through clinical and radiographic examinations. A questionnaire about the clinical condition of the tooth, evaluation of care and satisfaction with treatment was applied. Data on pre-and trans-operative were noted by the patient's clinical record. Endodontically treated teeth were examined by a specialist in endodontics, which compared with previous radiographs and current ones. The collected datas were presented descriptively by absolute numbers, percentages, averages. To determine the association between the independent and dependent variables was carried out through the bivariate association test Chi-square and Fisher exact test. Results: 79.8% presented with radiographic normal and 84.4% without pain symptoms. 8.2% of the teeth were fractured and 3.2% extracted. The persistence of the periapical lesion was associated with initial periapical status (p <0.05). 91.5% of patients are satisfied with the outcome of treatment. Such satisfaction is associated with absence of pain and an adequate esthetic tooth position (p <0.05). Conclusion: endodontic treatment in specialized dental clinics have an adequate technical quality, resulting in the success of endodontic therapy performed in these centers and that users are satisfied with the treatment

Acolhimento institucional e desenvolvimento moral: a generosidade em crianças de quatro a seis anos de idade em situação de abrigo

This research has as main proposal to verify how the virtue of generosity, considered as one of the important aspects of moral development on children, shows itself in children between four and six years old in institutional welcome condition. Toward this aim, knowledge in Human Development Psychology, specifically Jean Piaget and his contemporary collaborators, were associated to philosophic knowledge, with emphasis in Kant and Aristotle. The research took place in an institutional welcome service in the town of Natal-RN, between February and May of 2009, witch is responsible to offer care to children from zero till six years old. As procedure were used: the rulebased game Memory Game ; the childhood story One note fight ; and observations of the institution s everyday. The corpus analysis was done by the Thematic Content Analysis method. In general, in the daily observations, children showed themselves more co-operative and generous than in the executed procedures, mainly when the matter subject was other´s well-being. The duty, Kantian perspective, was overcome by the Aristotelian sumo bem, classified as generous act of afford to other what is not posted as right, however guaranteed by solidarity

Instrumentalidade do serviço social: dimensões teórico-metodológica, ético-política e técnico-operativa e exercício profissional

The dissertation proposes a discussion about the instrumentality of the Social Work, in the attempt of visualizing her, as well as the profession, in a totality perspective to the light of the rationality critical-dialetical. Understood as the capacity that the professional subjects acquire of giving answers to the demands that are placed to the profession, itself built partner-historically, in a teleologys conflicts and causalitys. So, it is proposed the discussion of the instrumentality while a group of you know specific, composed essentially by the development of three practical-formative dimensions. The theoretical-methodological refers to the capacity of apprehension of the method and of the theories and, consequently, of the relationship that does with the practice. The dimension ethical-politics concerns the development of the capacity of analyzing the society and the own profession as field of contradictory forces, being considered the character eminently political of the professional exercise, as well as the professional's conscience concerning the social direction that prints in your intervention. And the technician-operative dimension refers more strictly to the technical elements and you score for the development of the intervention. It was looked for to evidence as those dimensions they attend in the professional exercise, starting from the experience lived by the social workers of the Social Attendance Reference Centers, in Natal/RN

Em direção a uma representação para equações algébricas :uma lógica equacional local

The intervalar arithmetic well-known as arithmetic of Moore, doesn't possess the same properties of the real numbers, and for this reason, it is confronted with a problem of operative nature, when we want to solve intervalar equations as extension of real equations by the usual equality and of the intervalar arithmetic, for this not to possess the inverse addictive, as well as, the property of the distributivity of the multiplication for the sum doesn t be valid for any triplet of intervals. The lack of those properties disables the use of equacional logic, so much for the resolution of an intervalar equation using the same, as for a representation of a real equation, and still, for the algebraic verification of properties of a computational system, whose data are real numbers represented by intervals. However, with the notion of order of information and of approach on intervals, introduced by Acióly[6] in 1991, the idea of an intervalar equation appears to represent a real equation satisfactorily, since the terms of the intervalar equation carry the information about the solution of the real equation. In 1999, Santiago proposed the notion of simple equality and, later on, local equality for intervals [8] and [33]. Based on that idea, this dissertation extends Santiago's local groups for local algebras, following the idea of Σ-algebras according to (Hennessy[31], 1988) and (Santiago[7], 1995). One of the contributions of this dissertation, is the theorem 5.1.3.2 that it guarantees that, when deducing a local Σ-equation E t t in the proposed system SDedLoc(E), the interpretations of t and t' will be locally the same in any local Σ-algebra that satisfies the group of fixed equations local E, whenever t and t have meaning in A. This assures to a kind of safety between the local equacional logic and the local algebras
