To investigate the association between cytokine peripheral levels and the risk of cardiovascular disease in patients with schizophrenia and controls.
A sample of 40 patients and 40 control subjects ...participated in the study. Psychiatric diagnosis was established following structured clinical assessment. The Framingham Score was used to assess cardiovascular risk (CVR). Serum levels of the cytokines IL-1β, IL-6, IL-8, IL-10, IL-12p70 and TNF-α were determined by cytometric bead array (CBA) technique, and the serum levels of IL-33, sST2, sTNFR1, sTNFR2, Leptin and Adiponectin by Enzyme-Linked Immunosorbent assay (ELISA).
Patients with schizophrenia showed greater frequency of moderate CVR when compared with controls (p = 0.14). In addition, patients showed higher levels of sTNFR2 and Adiponectin compared to controls (p = 0.007 and p < 0.001, respectively). Adiponectin and sTNFR2 were associated with CVR only in patients (p = 0.0002 and p = 0.033, respectively). In multivariate analysis controlling for socio-demographic and clinical confounders, illness duration (r = 0.492; p < 0.002) and sTNFR2 (r = 0.665; p < 0.004) were independent predictors of CVR.
Our results reinforce the concept that patients with schizophrenia are at greater risk to develop cardiovascular diseases, and suggest that the associated chronic low-grade inflammation might play a role in this process.
Studies show great variation in prevalence of anti-thyroid antibodies in children with type 1 diabetes mellitus (DM1). There still is no consensus regarding screening of autoimmune thyroiditis in ...patients with DM1, especially in asymptomatic patients.
To investigate the natural history and prevalence of autoimmune thyroiditis in pediatric patients with DM1 and relate it to potential risk factors.
This study is a historical cohort, through research of the records of 474 patients with DM1 from 9 months to 25 years of age, between 1980 and 2005 - 222 boys (46.8%) and 252 girls (53.2%), with an average duration of DM1 of 9.3 +/- 5.8 years. The sample was selected by having at least one measurement of TSH and anti-thyroid autoantibodies (antithyroperoxidase or anti-microssomal and/or anti-thyroglobulin) at any time from diagnosis of DM1. A questionnaire was answered in order to study the variables of interest for the study. Thyroid function disorder was defined as altered levels of TSH, with or without altered free T4 levels.
A total of 383 patients (9 months to 25 years of age) were studied, 199 girls (52%) and 184 boys (48%). Sixty-four (16.7%) had positive anti-thyroid antibodies, predominantly girls (p = 0.064). Average duration of DM1 was 9.3 +/- 5.8 years and those above this age had a higher incidence of thyroiditis (p = 0.01). The prevalence of thyroid function disorder in patients with DM1 was 7.3% (n = 28), mostly with thyroiditis (32.8% vs 2.2% with negative antibodies, p < 0.001). There was a positive association between thyroiditis, as well as thyroid function disorders, and other autoimmune disorders (p < 0.001 and p < 0.02, respectively).
Prevalence of thyroiditis in the diabetic population is considerably higher than in the general population. Annual laboratory determinations of anti-TPO antibodies and dosage of TSH should be part of routine tests in the diabetic population, especially in girls, children with DM1 for > 9 years, patients above 12 years of age, and those in whom DM1 is associated with another autoimmune disease. Anti-thyroid antibody positivity may indicate the necessity for thyroid function testing at shorter intervals.
Objective: To test the hypothesis that genetic variations of cannabinoid receptors contribute to the pathophysiology of cognitive deficits in schizophrenia. Methods: In this genetic association ...case-control study, cannabinoid receptor polymorphisms CNR1 rs12720071 and CNR2 rs2229579 were tested for association with neurocognitive performance in 69 patients with schizophrenia and 45 healthy controls. Neurocognition was assessed by the Brief Assessment of Cognition in Schizophrenia (BACS). Results: We found a consistent association between CNR1 rs12720071 polymorphism and the cognitive performance of patients in several cognitive domains. Patients with C/C polymorphism presented significantly worse performance in motor speed, verbal fluency, attention/processing speed and reasoning/problem solving. Conclusion: Although limited, our data support the hypothesis that CNR1 variations may be associated with the pathogenesis of cognitive deficits of schizophrenia.
OBJETIVO: Analisar os resultados obtidos no Serviço de Cirurgia Geral do Hospital Universitário Cajuru - PUCPR, com o tratamento da gangrena de Fournier. MÉTODOS: Foram revisados os prontuários de 40 ...pacientes com diagnóstico de Gangrena de Fournier internados no hospital universitário Cajuru de Novembro de 1999 a Abril de 2006, analisando-se as variáveis: sexo, idade, fatores predisponentes, etiologia, localização da lesão, exames laboratoriais, procedimentos cirúrgicos realizados, antibioticoterapia e utilização de câmara hiperbárica. RESULTADOS: A etiologia mais comum foi de origem anorretal. O agente etiológico mais prevalente foi a E. coli. O fator predisponente predominantes foi a diabetes mellitus, A maioria dos pacientes eram do sexo masculino. A localização e extensão da lesão mais freqüente foi a perineal. Todos foram submetidos à desbridamento cirúrgico, 17 à colostomia e dois à cistostomia. Todos os pacientes utilizaram antibiótico, sendo os mais usados: metronidazol e gentamicina. Vinte e seis pacientes submeteram-se à terapia hiperbárica. A mortalidade global foi de 20%. CONCLUSÃO: A Síndrome de Fournier, apesar de todos os avanços terapêuticos atuais, continua apresentando altos índices de mortalidade. O reconhecimento precoce da infecção associado a tratamento agressivo e invasivo são medidas essenciais para se tentar diminuir esses índices prognósticos.
OBJECTIVE: To analyze the results obtained in the Department of General Surgery, Cajuru University Hospital - PUCPR, with the treatment of Fournier's gangrene. METHODS: We reviewed the charts of 40 patients diagnosed with Fournier's gangrene admitted to the Cajuru University Hospital from November 1999 to April 2006, analyzing gender, age, predisposing factors, etiology, lesion location, laboratory tests , surgical procedures, antibiotic use and hyperbaric oxygen therapy. RESULTS: The most common etiology was the anorectal origin. The most prevalent etiological agent was E. coli. The predominant predisposing factor was diabetes mellitus. The majority of patients were male. The location and extent of injury was usually in the perineum. All underwent surgical debridement, 17 with associated colostomy and two with combined cystostomy. All patients received antibiotics, the most used being metronidazole and gentamicin. Twenty-six patients underwent hyperbaric therapy. The overall mortality was 20%. CONCLUSION: Fournier's syndrome, despite all the advances in treatment today, continues to show high mortality rates. Early recognition of infection associated with invasive and aggressive treatment are essential for attempting to reduce these prognostic indices.
A persistência da artéria isquiática é uma rara variação anatômica, com poucos casos descritos na literatura, manifestando-se por formação de aneurisma, massa pulsátil em glúteo, isquemia aguda ou ...crônica de membro inferior e compressão de nervo isquiático. O diagnóstico é confirmado com exames de imagem: mapeamento duplex, angiotomografia e angiorressonância magnética. O tratamento é indicado nos casos sintomáticos ou quando há formação de aneurisma, realizado através de ligadura ou embolização por via endovascular, sendo necessário a revascularização do membro nos casos em que a artéria isquiática é a principal responsável pelo suprimento sangüíneo do membro. Apresentamos o caso de uma paciente do sexo feminino, 43 anos, com pseudoaneurisma de artéria isquiática confirmada por mapeamento duplex e angiorressonância magnética, com quadro de neuropatia isquiática por compressão nervosa e dor local. A paciente foi submetida à exploração cirúrgica com ligadura da artéria isquiática e remoção dos trombos. No seguimento de 12 meses, apresentou importante melhora da dor e realizou fisioterapia motora para recuperação das funções neurológicas do membro.

The persistent sciatic artery is a rare anatomical variation, with few cases described on the literature. It presents clinically as aneurysm formation, pulsate gluteal mass, acute or chronic limb ischemia and sciatic nerve compression. Diagnosis is confirmed by imaging methods: duplex scan, CT angiographt and magnetic resonance angiography. Treatment is indicated in symptomatic cases and when there is aneurysm formation and it is performed by ligation of the sciatic artery or endovascular embolization, associated with limb revascularization in the cases the sciatic artery is the main blood supply to the limb. We report the case of a 43 year-old female patient, ,with a false aneurysm of the sciatic artery confirmed by duplex scan and magnetic resonance angiography who had local pain and sciatic neuropathy due to neural compression. Surgical exploration was performed, with ligation of sciatic artery and thrombus removal. At the 12 months follow up there was significant pain relief and she was performing motor physical therapy to recover the neurological functions of the limb.

Lemierre syndrome is a rare disease. It often affects young adults and is most frequently caused by Fusobacterium necrophorum. The initial event is pharyngitis, which extends to the internal jugular vein, serving as source of continuous bacteremia and septic pulmonary emboli. Clinical manifestations include fever, respiratory distress, and swollen cervical lymph nodes. Diagnosis is established based on blood culture or direct blood culture and confirmed by computed tomography and/or duplex scan. Treatment consists of administration of beta-lactamase resistant beta-lactam antibiotics. Surgical exploration is rarely required. A 34-year-old woman with acute oropharyngeal infection presented 48 hours later with prostration, fever, and swollen and painful cervical lymph nodes on the left side of the neck. Chest radiography and tomography demonstrated multiple lung lesions. Computed tomography and duplex scan demonstrated thrombosis of the internal jugular vein, compatible with acute suppurative thrombophlebitis, also known as Lemierre syndrome. The patient received antibiotics and had clinical recovery. A control duplex scan demonstrated partial recanalization of the internal jugular vein.
