Internação psiquiátrica e a manutenção do tratamento extra-hospitalar

O objetivo desse trabalho foi identificar características comuns entre pessoas que tiveram alta hospitalar de internação psiquiátrica recente. Foi realizado um estudo quantitativo exploratório em um serviço ambulatorial de saúde mental. A amostra foi composta por pacientes egressos de internação. Utilizou-se um questionário e a pesquisa foi aprovada pelo CEP. Estrevistou-se 48 pacientes com idade média de 39 anos. Diagnósticos de Esquizofrenia e Transtornos Esquizotípicos foram prevalentes em 33,3% da amostra. Em média treze pacientes recebem alta de internação psiquiátrica hospitalar ao mês e 62,5% deles tinham internações anteriores. No período, 12,5% da amostra necessitou de reinternação. A internação psiquiátrica demonstrou ser um recurso necessário aos momentos de crise e parte da manutenção do tratamento psiquiátrico, principalmente dos transtornos mentais graves. O que evidencia a necessidade de uma manutenção adequada do tratamento nos serviços de atendimento comunitário para que a necessidade de reinternações seja evitada.

Glucosurie rénale [Renal glucosuria].

The occurrence of glucosuria in the absence of hyperglycemia is distinctive for renal glucosuria. SGLT2 mutations provoke familial renal glucosuria characterized by persistent glucosuria in the absence of any other renal tubular dysfunction. Renal glucosuria associated with others proximal tubular dysfunctions points to Fanconi syndrome. This generalized dysfunction of proximal tubule needs to be treated and may progress regarding its aetiology to chronic renal failure. The development and study of models of Fanconi syndrome has recently contributed to a better knowledge of the mechanisms implicated in the tubular transport of glucose and low-molecular-weight-proteins. This article reviews these recent developments.

Extra-articular knee resection for a secondary chondrosarcoma evolving from an isolated enchondroma of the distal femur: A case report.

Introduction: Enchondromas are among the most current benign bone tumours. Malignant degeneration is extremely rare (<1%) and generally presents as a low grade chondrosarcoma. For localized grade 1 lesions, the treatment of choice is curettage. Wide excision and reconstruction is generally not necessary, unless locally advanced or more aggressive behaviour is suspected at presentation. Case report: A healthy 72 yo male presented with pain and recurrent knee joint effusion. X-rays show a classical central distal metaphyseal enchondroma of the femur associated with subtle osteolysis of the lateral condyle. MRI confirms the presence of a locally aggressive chondromatous lesion based in a classical enchondroma. Core needle biopsy revealed a grade 1 chondrosarcoma, which was in contrast to the radiological aggressiveness of the lesion. Total body CT-scan did not reveal metastatic disease. A wide resection was planned, as a high-grade lesion and joint contamination was suspected. We performed an extra-articular knee resection and reconstruction with a hinged modular total knee megaprosthesis. The definitive histology was grade 1 chondrosarcoma, the surgical margins were wide. The evolution was favourable and the patient was able to perform all his activities of daily living independently without pain at 6 weeks postop. Knee flexion reached 90°. The oncologic screening at 18 months did not show local or distant recurrence. Conclusion: Joints near a benign tumour that suddenly become symptomatic or present an effusion might indicate a malignant transformation. Wide resection and prosthetic reconstruction remains an effective treatment option even in low grade cartilaginous lesions if (1) the adjacent joint is contaminated, or (2) joint-sparing surgery would result in a severe functional impairment of the limb.

Troubles du sommeil chez des patients présentant une insuffisance rénale chronique [Sleep disorders in patients with chronic renal insufficiency].

Sleep disorders, especially insomnia, daytime sleepiness, sleep apnea syndrome and restless legs syndrome are very frequently encountered in patients with chronic renal failure whether or not they undergo renal replacement therapy. The causes of sleep disorders are multifactorial and not only linked to the renal disease itself, but also to its treatment and its associated psychosocial factors. This article discusses the prevalence and physiopathology of the most frequently encountered sleep disorders in chronic renal failure patients, and highlights the actually available therapeutic options.

Bicarbonate de sodium pour ralentir la progression de la maladie rénale chronique [Sodium bicarbonate to slow the progression of chronic kidney disease].

Metabolic acidosis is a prevalent complication in moderate and late stages of chronic kidney disease (CKD). It is established that the correction of metabolic acidosis may improve metabolic bone disorders and protein degradation in the skeletal muscle, two characteristic complications of patients with advanced CKD. In the last 18 months, three randomized controlled trials have drawn the attention on a novel indication to correct metabolic acidosis in these patients, i.e., halting CKD progression. These data show that sodium bicarbonate, a cheap and easily manageable treatment, may delay the progression of CKD and the need of a renal replacement therapy such as dialysis or kidney transplantation.

Appropriate management of special situations in Crohn's disease (upper gastro-intestinal; extra-intestinal manifestations; drug safety during pregnancy and breastfeeding): results of a multidisciplinary international expert panel-EPACT II

Introduction: High-grade evidence is lacking for most therapeutic decisions in Crohn's disease. Appropriateness criteria were developed for upper gastro-intestinal, extra-intestinal manifestations and drug safety during conception, pregnancy and breastfeeding in patients with Crohn's disease, to assist the physician in clinical decision making. Methods: The European Panel on the Appropriateness of Crohn's Disease Therapy (EPACT II), a multidisciplinary international European expert panel, rated clinical scenarios based on evidence from the published literature and panelists' own clinical expertise. Median ratings (on a 9-point scale) were stratified into three categories: appropriate (7-9), uncertain (4-6 with or without disagreement) and inappropriate (1-3). Experts were also asked to rank appropriate medications by priority. Results: Proton pump inhibitors, steroids, azathioprine/6-mercaptopurine and infliximab are appropriate for upper gastro-duodenal Crohn's disease; for stenosis, endoscopic balloon dilation is the first-tine therapy, although surgery is also appropriate. Ursodeoxycholic acid is the only appropriate treatment for primary sclerosing cholangitis. Infliximab is appropriate for Pyoderma gangrenosum, ankylosing spondylitis and uveitis, steroids for Pyoderma gangrenosum and ankylosing spondylitis, adalimumab for Pyoderma gangrenosum and ankylosing spondylitis, cyclosporine-A/tacrolimus for Pyoderma gangrenosum. Mesalamine, sulfasalazine, prednisone, azathioprine/6-mercaptopurine, ciprofloxacin, and probiotics, may be administered safety during pregnancy or for patients wishing to conceive, with the exception that mate patients considering conception should avoid sulfasalazine. Metronidazol is considered safe in the 2nd and 3rd trimesters whereas infliximab is rated safe in the 1st trimester but uncertain in the 2nd and 3rd trimesters. Methotrexate is always contraindicated at conception, during pregnancy or during breastfeeding, due to its known teratogenicity. Mesalamine, prednisone, probiotics and infliximab are considered safe during breastfeeding. Conclusion: EPACT II recommendations are freely available online (www.epact.ch). The validity of these criteria should now be tested by prospective evaluation. (C) 2009 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.

La dénervation rénale unilatérale et le système kallikréine-bradykinine rénal chez le rat [Unilateral renal denervation and the renal kallikrein-bradykinin system in the rat].

AIM: The antihypertensive effect of renal denervation in hypertensive patients is partially explained by increased tubular natriuresis. To study the possible contribution of the kallikrein-kinin system (KKS) to this natriuretic effect in rats, we measured kallikrein activity (KA) and bradykinin concentrations (BK) in plasma and tissues. METHODS: To measure KA, we adapted and validated an enzymatic assay that cleaves para-nitroaniline (pNA) from the tripeptide H-D-Pro-Phe-Arg-pNA. The coefficients of variation (CV) within- and between-assays were less than 8% for plasma and tissue KA (plasma n=6 and 13; tissue n=4). Linear results for serially diluted samples confirmed the assay specificity. Tissue BK determinations were based on an established assay for plasma BK: tissue was homogenized and kinins extracted in ethanol, and BK was isolated by high-performance (HPLC) liquid chromatography and quantitated by radioimmunassay. Within- and between-assay CV for plasma BK were 18% (n=8 and n=35, respectively) and for BK in various tissues less than 16% (n=5-8). RESULTS: In male Wistar rats (n=3), plasma BK was 8.2±6.6 fmol/mL (mean±SD), and tissue BK (fmol/g) in 14 tested organs varied between brain (14±3) and submaxillary gland (521±315). Six days after left-sided unilateral renal denervation, left renal tissue BK (89±9) was not different from right renal BK (75±23). Similarly, KA was comparable in the two kidneys (left 18.0±1.5, right 15.8±1.4μkat/g). CONCLUSION: Any possible effect of unilateral renal denervation on the kidney's KKS would have to be bilateral.
