Efeitos de regras sobre comportamentos de cuidados com os pés em pessoas com diabetes

Dentre as complicações do Diabetes Mellitus (DM) encontra-se a amputação de membros inferiores, em decorrência do pé diabético. Medidas preventivas simples voltadas para os comportamentos de cuidados com os pés colaboram de forma significativa para a prevenção do pé diabético. Em virtude da gravidade e alta prevalência do pé diabético, vários estudos tem sido realizados com objetivo de identificar variáveis que contribuem para melhorar a adesão às medidas preventivas de cuidados com os pés em pacientes com diabetes. Entretanto, ainda não está claro quais os fatores que contribuem para estabelecer e manter comportamentos de cuidados com os pés. A proposta desta pesquisa foi identificar variáveis que contribuem para estabelecer e manter comportamentos de cuidado com os pés e que, desta forma, colaboram para evitar o surgimento do pé diabético em pessoas com diabetes. Ela se constituiu em três estudos: o primeiro, descritivo transversal, caracterizou-se como linha de base para os outros dois, que foram experimentais. A pesquisa se desenvolveu em uma unidade básica de saúde na cidade de Belém – Pará. O primeiro estudo investigou: as regras (orientações) relacionadas aos cuidados com os pés apresentadas pelos profissionais de saúde do programa Hiperdia, aos pacientes com diabetes; o repertório comportamental de 54 participantes com diabetes acerca dos cuidados com os pés; e o estado de saúde dos pés dos pacientes com diabetes. O segundo investigou o efeito de regras no estabelecimento e manutenção de comportamentos de cuidados com os pés em pessoas com diabetes, quando foi manipulada à apresentação, ou não, de perguntas acerca dos cuidados com os pés; e, a realização, ou não, de o exame dos pés. O terceiro investigou em 16 pacientes os efeitos de regras no estabelecimento e manutenção de comportamentos de cuidado com os pés em pessoas com diabetes, quando: (a) o relato de seguimento de regras de cuidado com os pés produziu reforço social; (b) eram apresentadas regras que especificavam justificativas para o seguimento de regras de cuidados com os pés; (c) eram apresentadas regras que especificavam justificativas para o seguimento de regras de cuidado com os pés e o relato de seguimento de regras de cuidado com os pés produziu reforço social; e, (d) o relato de seguimento de regras de cuidados com os pés não produziu o reforço social e as regras apresentadas não continham as justificativas para os cuidados com os pés. Os resultados do Estudo 1 apontaram que a apresentação de instruções sobre cuidados com os pés pelos profissionais de saúde é insuficiente, o repertório comportamental de cuidados com os pés é precário e há presença de riscos para desenvolver pé diabético entre os pacientes. De modo geral, as manipulações realizadas tanto no Estudo 2 quanto no Estudo 3, favoreceram acréscimos de comportamentos novos de cuidados com os pés no repertório comportamental dos pacientes. Estes dados sugerem que o seguimento de regras de cuidados com os pés depende: (a) do contato com as consequências aversivas em decorrência do não seguimento de regras; (b) da apresentação de perguntas que favorecem a autodescrição do comportamento, (c) da apresentação de reforçadores sociais, (d) da apresentação das justificativas para a emissão do comportamento, (e) da apresentação combinada de justificativas para a emissão do comportamento e de consequências para o comportamento emitido; (f) da exposição a um maior número de condições favoráveis para o seguimento de regras; (g) do histórico pré-experimental de seguimento de regras; e (h) da monitoração do comportamento de seguir regras por profissionais de saúde.

Meu corpo dependente: representações sociais de pacientes diabéticos

Este estudo tem como objetivos: caracterizar as representações sociais de clientes diabéticos sobre o seu corpo após a amputação e analisar a relação dessas representações para o cuidado de si.

Osteossarcoma apendicular: revisão de literatura

Osteosarcoma is the most common primary bone cancer in dogs. It affects most commonly dogs of big or giant breeds with 7 to 8 years and the etiology is unknown. Osteosarcoma is defined as a bone matrix-producing malignant mesenchymal tumor and has a predilection for the metaphyseal region of appendicular skeleton, however, it can affect axial skeleton and soft tissues. Distal radius is the most commonly affected site. The definitive diagnosis of osteosarcoma can be obtained with history, physical examination, radiographs and biopsy. Lung is the most common organ for metastatic disease. The mainly treatment for osteosarcoma is limb amputation and systemic chemotherapy for metastatic disease control. Limb-sparing surgery is a viable alternative to amputation for dogs with concomitant conditions that impede limb amputation. Palliative treatments for osteosarcoma have been studied such as local and systemic radiotherapy, immunotherapy and biphosphonates. This study has the objective of presenting the aspects of diagnosis and treatment for appendicular osteosarcoma

Avaliação do Efeito Fotodinâmico sobre o Crescimento in vitro de Pythium insidiosum

Photodynamic Therapy (PDT) is a therapeutic method which employs a photosensitizer and light to cause cellular death. The chemical compounds have low or none toxicity for hosts cells. Under the incidence of light, in an appropriated wavelength, these chemical compounds produce reactive oxygen which affects the biomolecules of the target-cells. The specific illumination of the affected area increases the selectivity of the therapy, since the photodynamic process occurs only in the irradiated area. Pythiosis, for instance, is a life-threatening emerging disease caused by a fungus-like organism called Pythium insidiosum. The disease occurs in man and other animals, being mostly observed in horses. Human pythiosis may present as ophthalmic, cutaneous-subcutaneous and systemic forms of lesions. Due to the fact that P. insidiosum is not a true fungus, it is refractory to most antifungal drugs and the treatment of the disease is difficult. Extensive surgery procedures, such as limb amputation, are the treatment of choice, however relapses may occur frequently. Although not totally effective, the use of immunotherapy associated to surgery have shown some results. Considering that pythiosis is an emerging disease few explored in its etiological and therapeutic aspects, which are limited and few effective, it is of great importance to encourage the development of researches for new strategies of treatment. In this sense, it was evaluated the effect of PDT on in vitro growth of the pathogen employing two chemical compounds as photosensitizer, porphyrin and chlorine, at different concentrations in combination with several energetic dosages. Porphyrin showed inhibition of growth at 25mg/mL with 100J/cm2 of energetic dosage and chlorine showed similar results employing low concentrations (0,7, 1,0 and 1,3mg/mL) with 70J/cm2 of energetic dosage...

Aspectos clínicos e cirúrgicos do osteossarcoma canino

Osteosarcoma is the primary osseous neoplasia frequently diagnosed in dogs and it’s the main answerable for more than 85% of the neoplasias origened from the skeleton. The average age of onset of the lesion is 7 years, especially in large breeds and giant, with males being more affected than females. In general, 75% of osteosarcomas develop in the appendicular skeleton and 25% in the axial. The forelimbs are more affected than the hindlimbs, since support 60% of body weight. The osteosarcoma diagnosis is made by the analys of the animal’s clinic historic, detailed physique exams, blood exams alkaline phosphatase, xray exams, cytology, biopsy. The treatment of choice is the amputation associated to the chemotherapy. However, in some cases the member is preserved by the allograft technic. The chemotherapy associated to the surgery reduces the total load of the tumor, lengthens the interval of the life and improves the quality of pacient’s life. The most used medicines are cisplatin and doxorubicin. They can be used in separated or associated ways. The prognostic of dogs with osteosarcoma is reserved

Phantom eye syndrome: a review of the literature

The purpose of this literature review was to describe the main features of phantom eye syndrome in relation to their possible causes, symptoms, treatments, and influence of eye amputation on quality of life of anophthalmic patients. For this, a bibliographical research was performed in Pubmed database using the following terms: eye amputation, eye trauma, phantom eye syndrome, phantom pain, and quality of life, associated or not. Thirteen studies were selected, besides some relevant references contained in the selected manuscripts and other studies hallowed in the literature. Thus, 56 articles were included in this review. The phantom eye syndrome is defined as any sensation reported by the patient with anophthalmia, originated anophthalmic cavity. In phantom eye syndrome, at least one of these three symptoms has to be present: phantom vision, phantom pain, and phantom sensations. This syndrome has a direct influence on the quality of life of the patients, and psychological support is recommended before and after the amputation of the eyeball as well as aid in the treatment of the syndrome. Therefore, it is suggested that, for more effective treatment of phantom eye syndrome, drug therapy should be associated with psychological approach.

Kasabach-Merritt syndrome: clinical vs. surgical treatment

Kassabach-Merritt syndrome is a combination of capillary hemangioma and thrombocytopenia that predisposes to bleeding with petechiae, ecchymosis and spontaneous bruising. Treatment is generally started with corticosteroids, interferon alpha or chemotherapy. We present the case of a child (aged 1 year and 9 months) with a giant hemangioma, from the root of the thigh to the knee, and thrombocytopenia. Treatment was started with corticosteroids, without improvement, and then intra-tumor and cutaneous bleeding appeared spontaneously. The patient’s clinical condition precluded prescription of vincristine and interferon and emergency tumor resection was conducted because of extreme thrombocytopenia and bleeding. The child then began to develop sepsis with hypotension and ischemia of remnant tissues. This case presented a therapeutic challenge, which is the subject of this article.

Retorno à atividade reprodutiva de touro angus após fimose traumática com obliteração parcial da luz prepucial: relato de caso

The main disturbs affecting the genital segment of bulls are balanitis, phimosis and preputial injuries, abscesses or prolapses, resulting in decreased libido or mating ability. One case of traumatic phimosis with partial obliteration of preputial lumen is reported in Aberdeen Angus bull. During anamnesis, it was reported that the animal was unable to expose the penis and presented increased penile and preputial volume of unknown etiology after being submitted to a libido test. During clinical examination, a firm preputial mass of 15 cm in diameter was observed in the middle third of the prepuce and stenosis of preputial lumen was detected approximately 17 cm from the preputial orifice. Reconstructive surgery was the chosen therapy, with amputation of the affected foreskin portion. A skin segment of about 12 cm and affected mucosal portion were removed. Postoperative therapy consisted of dressing with chlorhexidine digluconate based ointment, povidone iodine and topical insect repellent (cypermethrin and carbamyl), systemic antibiotic therapy with benzathine penicillin (30,000 IU / kg, repeated after 48 hours) and anti-inflammatory therapy with flunixin meglumine (2 , 0 mg / kg SID) for three days. After twenty days, semen was collected by massage of the accessory glands. The ejaculate volume was 3 mL, with 200x106 spermatozoa / mL, white color, "suis generis" odor, 88% of motile sperm, 64% of progressively motile sperm and 82% of rapid sperm. Thus, the chosen surgical treatment was effective to correct the pathology and reintroduce the animal into reproductive activity

Clinico-genetic aspects of a pediatric non-neurofibromatosis type 1 malignant triton tumor with loss of chromosome X

Malignant triton tumor (MTT) is an aggressive peripheral nerve sheath tumor with rhabdomyoblastic differentiation. Less than 100 cases have been described, being mostly male children with type 1 neurofibromatosis. We report a 6-year-old female with MTT and no diagnostic criteria for neurofibromatosis type 1. Cytogenetic analysis showed a 46,X,-X[4]/46,XX[16] karyotype. She underwent a transfemoral amputation and chemotherapy and is free of disease 15 months after diagnosis. The few cytogenetic studies of MTT described in the literature have been inconclusive. Further cytogenetic analyses are needed to understand the role of chromosome X monosomy in the pathogenesis of this rare tumor. Pediatr Blood Cancer 2012; 59: 13201323.

Gram-negative osteomyelitis: clinical and microbiological profile

Introduction: Despite the growing interest in the study of Gram-negative bacilli (GNB) infections, very little information on osteomyelitis caused by GNB is available in the medical literature. Objectives and methods: To assess clinical and microbiological features of 101 cases of osteomyelitis caused by GNB alone, between January 2007 and January 2009, in a reference center for the treatment of high complexity traumas in the city of Sao Paulo. Results: Most patients were men (63%), with median age of 42 years, affected by chronic osteomyelitis (43%) or acute osteomyelitis associated to open fractures (32%), the majority on the lower limbs (71%). The patients were treated with antibiotics as inpatients for 40 days (median) and for 99 days (median) in outpatient settings. After 6 months follow-up, the clinical remission rate was around 60%, relapse 19%, amputation 7%, and death 5%. Nine percent of cases were lost to follow-up. A total of 121 GNB was isolated from 101 clinical samples. The most frequently isolated pathogens were Enterobacter sp. (25%), Acinetobacter baumannii (21%) e Pseudomonas aeruginosa (20%). Susceptibility to carbapenems was about 100% for Enterobacter sp., 75% for Pseudomonas aeruginosa and 60% for Acinetobacter baumannii. Conclusion: Osteomyelitis caused by GNB remains a serious therapeutic challenge, especially when associated to nonfermenting bacteria. We emphasize the need to consider these agents in diagnosed cases of osteomyelitis, so that an ideal antimicrobial treatment can be administered since the very beginning of the therapy.

LIMB REPLANTATION AFTER AVULSION INJURIES: TECHNIQUES AND TACTICS FOR SUCCESS

Objectives: Retrospective evaluation of cases of limb replantation after avulsion injuries. Evaluation of the techniques and tactics used, that contributed to success and good functional results. Methods: Forty-three patients' records were assessed. All the cases had been submitted to limb replantation after avulsion injuries. Results: The majority of the cases were young men. The most common injury was to the thumbs. The surgical techniques and tactics used were: nerve grafting, vein grafting, transposition of the digital vessels, limb shortening, and heterotopic replantation. The most commonly used technique was vein graft. The limb survival rate was high (93%), as was patient satisfaction. Conclusion: Replantation after avulsion injury depends on the correct diagnosis of the limb viability and the use of appropriate surgical techniques and tactics for each case. The experience of the team of surgeons and a good hospital structure are essential for good results. There are few articles in medical literature about the indications, techniques and results of limb replantation after avulsion injuries. We believe that this retrospective evaluation can bring new information and contributions to the correct management of this highly complex situation. Level of evidence IV, Case Series.
