Profile of patients with Baggio-Yoshinari Syndrome admitted at "Instituto de Infectologia Emilio Ribas"

The aim of this study was to evaluate the epidemiological, clinical and laboratorial profile of patients with Baggio-Yoshinari Syndrome (BYS), who underwent internment at the Instituto de Infectologia Emilio Ribas in São Paulo, Brazil, during the period from July 1990 to July 2006. BYS is a new Brazilian tick-borne disease caused by Borrelia burgdorferi sensu lato microorganisms that resembles features of Lyme disease (LD), except for its epidemiological, clinical and laboratorial particularities. From 60 patients' records with positive serology to B. burgdorferi done by ELISA and Western-blotting methods, 19 cases were diagnosed as having BYS, according to criteria adopted at LIM-17 HCFMUSP, the Brazilian Reference Laboratory for the research of BYS. The other 41 remaining patients displayed miscellaneous infections or auto-immune processes. The beginning of symptoms in BYS group varied from one day to six years, from the onset of the disease. Four of 19 patients were included in acute disease stage, and 15 in latent. General unspecific symptoms were identified in almost all cases, with high frequencies of fever (78.9%) and lymphadenomegaly (36.8%). Six patients had skin lesions (31.5%); six arthralgia or arthritis (31.5%) and eight neurological symptoms (42%). Interestingly, two patients showed antibodies directed to B. burgdorferi exclusively in cerebrospinal fluid. Since BYS is a new emergent Brazilian zoonosis and its diagnosis is sometimes complex, all the new knowledge about BYS must be scattered to Brazilian Medical specialists, aiming to teach them how to diagnose this amazing tick-borne disease and to avoid its progression to chronic irreversible sequels

A comunicação entre o diretor e os professores no agrupamento X

A comunicação é essencial nas relações interpessoais, quer ao nível das organizações em geral, quer na organização escolar em particular. As funções de administração, como planeamento, organização, liderança e controle, são levadas a cabo com sucesso, dentro de uma organização quando apoiadas num processo de comunicação eficaz. O objectivo deste estudo foi procurar soluções para a ineficácia relativa do processo de comunicação entre o Diretor e os professores no Agrupamento X. Metodologicamente desenvolveu-se um estudo de caso, de natureza qualitativa, onde se recorreu a instrumentos de recolha de dados como entrevistas e ‘focus group’. Desta forma identificou-se e descreveu-se o processo de comunicação adotado no Agrupamento X entre o Diretor e os professores, bem como se recolheram as opiniões dos docentes e do Diretor sobre a comunicação e a gestão da informação no Agrupamento. Este estudo permitiu reconhecer que a fraca internalização de alguns conceitos e mecanismos do processo comunicacional por parte dos atores contribui para ineficácia relativa deste processo. Na criação do plano de ação retomámos e valorizamos a ideia de que um modelo de comunicação assente nas principais funções da comunicação poderá ser a chave para o maior envolvimento dos docentes na consecução dos objetivos do Projeto Educativo do Agrupamento, ou seja, é dada a resposta à pergunta partida deste projeto – como melhorar o processo de comunicação entre o Diretor e os professores no Agrupamento X?

Acute inflammatory demyelinating polyradiculoneuropathy (Guillain-Barré syndrome) following dengue fever

This paper reports a case of dengue in a six-year-old female child who suddenly developed excruciating headaches, fever, myalgia and paresis. Laboratory examinations included blood count, platelet count, biochemical tests (BUN, creatinine, aminotransferases, and total bilirubin and bilirubin fractions) and specific IgM titers (enzyme-immunoassay with recombinant tetravalent dengue). After ten days of hospitalization and having already been in a home environment, a new clinical image emerged, characterized by dysphagia, dysphonia, weakness, peripheral facial palsy and paresthesia. The diagnosis of Guillain-Barré Syndrome was based on clinical findings, cerebrospinal fluid examination, electrophysiological findings and the exclusion of other pathologies. Our case, as some shown in previous reports, calls attention to the possibility that Guillain-Barré Syndrome may occur in association with dengue.

TINU syndrome – Two Clinical Cases of Tubulo-Interstitial Nephritis and Uveitis

TINU (Tubulo-Interstitial Nephritis and Uveitis)syndrome is a rare disease of unknown aetiology characterised by the association between interstitial nephritis and uveitis. The authors present the cases of two young children whose symptoms began with anorexia and weight loss, associated with renal failure and proteinuria of tubular origin. One child also presented anaemia, glycosuria without hyperglycaemia and microhaematuria. A few months later both developed uveitis. In both cases the renal biopsy showed changes compatible with interstitial nephritis. As interstitial nephritis and uveitis aetiologies were not identified, TINU syndrome was suggested as a possible diagnosis. In both children there was a complete resolution, with one needing systemic steroids and immunosuppressive treatment. TINU syndrome should always be considered in the differential diagnosis of patients with renal and ophthalmologic changes.

Giant Pericardial Cyst Mimicking Dextrocardia on Chest X-Ray

Pericardial cysts are rare benign congenital malformations, usually small, asymptomatic and detected incidentally on chest X-ray as a mass located in the right costophrenic angle. Giant pericardial cysts are very uncommon and produce symptoms by compressing adjacent structures. In this report, the authors present a case of a symptomatic giant pericardial cyst incorrectly diagnosed as dextrocardia on chest X-ray.

Nephrotic syndrome associated with toxoplasmosis: report of seven cases

The concomitance of nephrotic syndrome and acute infection by Toxoplasma gondii is a rare occurrence in humans. In this paper seven cases of children, ranging from 11 months to 7 year-old, with concomitant nephrotic syndrome and asymptomatic acute T. gondii infection are reported. In one of those patients only the administration of anti-Toxoplasma therapy was enough to control the clinical and laboratory manifestations of the disease. In the other patients it was necessary to introduce corticosteroids or other immunosuppressant drugs. Three patients had complete clinical and laboratory improvement and the remaining showed only a partial response.

Gastric Outlet Obstruction in a Patient with Bouveret's Syndrome: a Case Report

BACKGROUND: Gallstone ileus accounts for 1% to 4% of cases of mechanical bowel obstruction, but may be responsible for up to 25% of cases in older age groups. In non-iatrogenic cases, gallstone migration occurs after formation of a biliary-enteric fistula. In fewer than 10% of patients with gallstone ileus, the impacted gallstones are located in the pylorus or duodenum, resulting in gastric outlet obstruction, known as Bouveret's syndrome. CASE PRESENTATION: We report an 86-year-old female who was admitted to hospital with a 10-day history of persistent vomiting and prostration. She was in hypovolemic shock at the time of arrival in the emergency department. Investigations revealed a gallstone in the duodenal bulb and a cholecystoduodenal fistula. She underwent surgical gastrolithotomy. Unfortunately, she died of aspiration pneumonia on the fourth postoperative day. CONCLUSION: This case shows the importance of considering Bouveret's syndrome in the differential diagnosis of gastric outlet obstruction, especially in the elderly, even in patients with no previous history of gallbladder disease.

Miopatia Miotubular Ligada ao Cromossoma X - Caso Clínico

Introdução:A miopatia miotubular ligada ao cromossoma X e uma miopatia congénita grave neonatal que afecta o sexo masculino, com prognóstico reservado. Relato de Caso: Lactente com hipotonia generalizada grave detectada após o nascimento, atrofia muscular generalizada e abolição dos reflexos osteotendinosos, cujo estudo etiológico específico (biópsia muscular e estudo de genética molecular) revelo tratar-se de miopatia miotubular ligada ao cromossoma X. Internado em Unidade de Cuidados Intensivos até aos oito meses, foi submetido a traqueostomia e gastrotomia, tendo alta para domicílio. Faleceu aos dez meses, subitamente, de causa indeterminada. Discussão: Este caso mostra que, apesar da terapêutica actual ser apenas paliativa, a importância do conhecimento do mecanismo genético é enorme, abrindo novos horizontes para uma terapia génica no futuro.

Acute gouty arthritis as a manifestation of immune reconstitution inflammatory syndrome after initiation of antiretroviral therapy

Immune reconstitution inflammatory syndrome (IRIS) in HIV-infected subjects initiating antiretroviral therapy most commonly involves new or worsening manifestations of previously subclinical or overt infectious diseases. Reports of non-infectious IRIS are much less common but represent important diagnostic and treatment challenges. We report on a 34-year-old HIV-infected male patient with no history of gout who developed acute gouty arthritis in a single joint one month after initiating highly active antiretroviral therapy.

Neurogenic Thoracic Outlet Syndrome Associated with Cervical Rib

A true neurogenic thoracic outlet syndrome (TOS) associated with a cervical rib is considered extremely rare. The authors present their experience with 5 cases of true neurogenic TOS associated with a cervical rib. All patients were female and had a cervical rib confirmed radiographically pre-operatively. Average age was 34,8 years. Although all patients had been treated with several combinations of diverse drugs and a rehabilitation program before referral to surgery, all described their pain as intense and debilitating before surgical treatment. All patients had pre-operative electromyographic abnormalities. Patients were operated on via a supraclavicular approach and the cervical rib was resected. No intra-operative or postoperative complications were noted. Two years postoperatively, all patients mentioned improvement. However, only 2 were symptomless, and on no medication. In one patient there was significant improvement, and in the remaining 2 patients some residual pain persisted that had to be dealt with pharmacologically. All patients were able to resume their daily life activities. Recovery was poorer in the 2 patients that had been referred to surgery after a longer period of time since the beginning of symptoms.

RRH: envenoming syndrome due to 200 stings from Africanized honeybees

Envenoming syndrome from Africanized bee stings is a toxic syndrome caused by the inoculation of large amounts of venom from multiple bee stings, generally more than five hundred. The incidence of severe toxicity from Africanized bee stings is rare but deadly. This report reveals that because of the small volume of distribution, having fewer stings does not exempt a patient from experiencing an unfavorable outcome, particularly in children, elderly people or underweight people.
