Intercostal nerve mononeuropathy: study of 14 cases

Este trabalho apresenta estudo retrospectivo de 14 pacientes com mononeuropatia de nervo intercostal (MNI), obtidos dentre 5.560 exames eletromiográficos, realizados de janeiro de 1991 até junho de 2004, em nosso Hospital Universitário. MNI foi encontrada em 14 pacientes, tendo como causas prováveis intervenções cirúrgicas torácicas em 6 (43%), neuropatia por herpes-zoster em 4 (28%), provável neurite de nervo intercostal em 2 (14%), neoplasia pulmonar em 1 (7%) e radiculopatia em 1 (7%). As principais causas de MNI de nosso Serviço são similares às da literatura. Os antidepressivos tricíclicos e anticonvulsivantes foram os fármacos mais utilizados no controle da dor.

Tuberculose ativa em pacientes cirúrgicos com baciloscopia negativa no pré-operatório

OBJETIVO: Verificar a proporção de pacientes com baciloscopia negativa no pré-operatório e que apresentaram TB ativa na peça cirúrgica. MÉTODOS: Estudo retrospectivo de pacientes com diagnóstico histopatológico de TB ativa ou sequelar e operados entre os anos de 2003 e 2006 em um hospital universitário. Foram pesquisados antecedentes e aspectos clínicos relativos à doença, pesquisa de bacilos álcool-ácido resistentes (BAAR), tipo de cirurgia realizada e exame histopatológico da peça cirúrgica. RESULTADOS: Foram incluídos 43 pacientes, com média de idade de 44 ± 19 anos, sendo 27 do sexo masculino. Apresentavam história prévia de TB com tratamento adequado 28 pacientes, e 15 não referiam antecedentes para TB. O principal motivo da procura pelo serviço foi infecção de repetição, seguida por achados em exames de imagem. Dos 43 pacientes, foi pesquisado BAAR no pré-operatório em 35: 32 apresentaram resultados negativos e 3, resultados positivos. Dos 35 pacientes pesquisados, 26 apresentavam diagnóstico histopatológico de TB ativa e 9 de TB sequelar na peça cirúrgica; os outros 8 também foram diagnosticados com TB sequelar. A proporção de TB ativa em doentes com baciloscopia negativa foi de 72% (23/32), e o de baciloscopia negativa em TB ativa foi de 88% (23/26), sendo a pesquisa de BAAR positiva somente em 11,5% (3/26). CONCLUSÕES: A baciloscopia direta tem rendimento muito baixo, e muitos pacientes mesmo já tratados podem permanecer com TB em atividade com baciloscopia negativa. A TB ativa pode ser confundida com infecções secundárias ou com câncer.

OSLERUS OSLERI (COBBOLD, 1876) INFECTION IN MANED WOLF (CHRYSOCYON BRACHYURUS, ILLIGER, 1815)

Oslerus osleri is a small nematode that infects the respiratory tract of domestic and wild canids and is responsible for causing chronic nodular tracheobronchitis. This paper aims to report a case of parasitism by O. osleri in a free-living maned wolf (Chrysocyon brachyurus) that was struck by a motor vehicle. Fecal samples were collected, and the presence of spiral larvae, with S-shaped tails, was observed on flotation. This characteristic was compatible with the Filaroididae Family larvae of O. osleri. Although the animal did not show clinical signs of respiratory system impairment, a tracheobronchoscopy was performed. Semitransparent nodules, 5 mm in diameter, containing adult parasites were observed in the third distal portion of the trachea, cranial to the carina. Larval morphological characteristics and the nodular locations were compatible with an O. osleri respiratory tract infection.

Management of tracheobronchial foreign body in children

To study cases of foreign bodies (FB) in the tracheobronchial tree investigating the clinical and radiological FB characteristics, complications and endoscopic and surgical intervention. Medical and radiological records review of all FB aspiration cases treated at S (a) over tilde uo Paulo State University Hospital over the last 30 years. One hundred and sixty-four FB cases were analyzed; 57% were male, 84% of these were under 16 years old. The most common clinical manifestations were coughing (68.3%) and choking (54.9%). The most common FBs were seeds (peanut, bean, maize) and also small metal or plastic objects. Radiography was normal in 21.3%, atelectasis was present in 40.9%, hyperinsufflation in 17.1% and the FB was radio-opaque in 20.7%. FB time in the bronchial tree varied from hours to years. The most serious complications, as fibroatelectasis and difficult resolution pneumonia, were caused by the long time that the FB remained in the bronchial tree. FB extraction was by endoscopy in 89% of cases, while 6% required surgical extraction or resection of destroyed part of lung, and 5% spontaneously eliminated the FB. There was no mortality in this series. Coughing and choking were the commonest clinical findings. Most FBs were dried seeds. Complications were due to delays in diagnosis, and most would not have existed if the doctor had given credence to the history. Radiography can be normal as most FBs are radiotransparent. FB extraction was by endoscopy, but a few cases required surgery and others were spontaneously eliminated.

Persistent Pleuropulmonary Air Leak Treated with Autologous Blood: Results from a University Hospital and Review of Literature

Background: Persistent air leak after pulmonary resection is a difficult complication for thoracic surgeons to manage. Objectives: To show the results of our experience treating persistent pleuropulmonary air leak with autologous blood and review the literature on this specific method of treatment. Methods: Retrospective study of patients with persistent aerial pleuropulmonary fistula treated with autologous blood. The patient's own blood was collected from a peripheral vein and directly introduced through the pleural drain. An inverted siphon was located in the drainage system to avoid prolonged clamping of the drain. This siphon impeded blood return but not air escape. Results: Between January 2001 and August 2008, 27 patients were treated by the above method. Patient age ranged from 2 to 74 years, and 78% were male. Each procedure used a mean quantity of 92 ml blood. Mean persistent air leak time before pleurodesis was 10.6 days and mean time to fistula resolution after pleurodesis was 1.5 days. Twenty-three (85%) patients had persistent pleuropulmonary air leak closed with the above procedure. Conclusion: Treating persistent pleuropulmonary air leak with autologous blood is promising, but further studies are required to quantify its real effectiveness. Copyright (C) 2009 S.

Câncer de pulmão: histologia, estádio, tratamento e sobrevida

OBJETIVO: Analisar os principais tipos histológicos, estádio, tratamento e sobrevida dos portadores de câncer de pulmão. MÉTODOS: Estudo retrospectivo a partir da análise dos prontuários de pacientes acompanhados no Hospital das Clínicas da Faculdade de Medicina de Botucatu, num período de seis anos. RESULTADOS: de janeiro de 2000 a janeiro de 2006, foram acompanhados 240 doentes com câncer de pulmão, com predominância do sexo masculino (64%). O tipo histológico mais freqüente foi o carcinoma escamoso (37,5%), seguido pelo adenocarcinoma (30%), carcinoma neuroendócrino (19,6%) e carcinoma de grandes células (6,6%). Apenas 131 pacientes (54,6%) foram tratados. Destes, 52 pacientes (39,7%) foram submetidos à quimioterapia exclusiva, 32 (24,4%) realizaram quimioterapia associada à radioterapia e 47 (35,9%) foram submetidos à cirurgia associada ou não à quimioterapia exclusiva e/ou radioterapia. Somente 27 pacientes (20,6%) foram submetidos à cirurgia exclusiva.Em relação ao estadiamento, 34,4% apresentavam, no momento do diagnóstico, estádio IV, 20,6% estádio IIIB, 16,8% estádio IIIA e os outros 28,2% pertenciam aos estádios I e II. A sobrevida em cinco anos foi de 65% para o estádio I e 25% para os estádios remanescentes. CONCLUSÕES: O tipo histológico predominante foi o carcinoma escamoso e o de menor freqüência foi o carcinoma de grandes células. A maioria se encontrava em estádio avançado ao diagnóstico, estando nos estádios iniciais menos de 30% dos casos. Isto justifica a baixa sobrevida e a pequena quantidade de pacientes submetidos ao tratamento cirúrgico exclusivo, em comparação à maioria que foi submetida à quimioterapia exclusiva.

Cytogenetic studies of Brazilian pediatric myelodysplastic syndrome cases: challenges and difficulties in a large and emerging country

Myelodysplastic syndromes (MDS) and juvenile myelomonocytic leukemia (JMML) are rare hematopoietic stem cell diseases affecting children. Cytogenetics plays an important role in the diagnosis of these diseases. We report here the experience of the Cytogenetic Subcommittee of the Brazilian Cooperative Group on Pediatric Myelodysplastic Syndromes (BCG-MDS-PED). We analyzed 168 cytogenetic studies performed in 23 different cytogenetic centers; 84 of these studies were performed in patients with confirmed MDS (primary MDS, secondary MDS, JMML, and acute myeloid leukemia/MDS+Down syndrome). Clonal abnormalities were found in 36.9% of the MDS cases and cytogenetic studies were important for the detection of constitutional diseases and for differential diagnosis with other myeloid neoplasms. These data show the importance of the Cooperative Group for continuing education in order to avoid a late or wrong diagnosis.

Do mundo como norma ao lugar como forma: o uso do território pela estratégia da saúde da família

This work aims to check whether there is a congruence between the purposes of regulations imposed by SIAB and the materiality constitution of places where your information is produced, since our hypothesis is that there is a mismatch between the rules and forms, which means, between reality as it is in places and how the territory is scrutinized by the Family Health Strategy (FHS) as for the performance of their teams as to the generation of their information. For this, the methodology used was the literature, documentary and empirical research, in special about territorialization of the Family Health strategy of Natal-RN. From the empirical mediation was possible to see the gap between full exploration and information produced by the ESF and the reality of the places. Thus, we highlight the importance of considering the conditioning of geographical forms as a guiding principle of the strategy for Family Health

Lugar, saúde e informação: os círculos de informação da atenção básica do SUS no contexto na disputa pelo conceito de saúde

Through the analysis of the informational activity at the primary care of SUS at the scale of places, this dissertation has as central objective to observe the dispute for the concepts of health and sickness, in the ambit of Brazilian Health Movement, featuring, on one hand, the clinic, biomedical or flexnerian line hegemonic, scientifically restrict and the primary frame of references for the Brazilian health politics and on the other hand a multiplicity of new proposals and critic thoughts to the current model, which have , as common characteristic, the worry with a territorial way of thinking the health context, therefore beyond the biological processes. On the first chapter we jut out with details these scientific and ideological movements, on a wider way, but also on the specificities of the public health s information politics. On the second chapter we analyze the downward health information circle at the basic care, observing the operational processes of the information s technical systems SIAB and e-SUS. On the third and last chapter, we give references to think about an upward health information circle, centered on the places, ruled by the notions of autonomy, organic solidarity and communicational density. It would possess, as method s primary horizon, the local organization of production and managing of information through the work of the Health Community Agent, privileging therefore the urgency of the most contingent needs of the people in theirs every day s life

Prevention of Risky drinking among students at a Brazilian University

Aim: The aim of this paper was to compare the quantity and frequency of alcohol use and its associated negative consequences between two groups of college students who were identified as being risky drinkers. Subjects were randomly allocated in a clinical trial to intervention or control groups. Methods: Risky drinking use was defined as Alcohol Use Disorders Identification Test (AUDIT) >= 8 and/or Rutgers Alcohol Problem Index (RAPI) >= 5 problems in the previous year. Students who had undergone the Brief Alcohol Screening and Intervention for College Students (BASICS) (N = 145 at baseline; 142 at 12 months, and 103 at 24 months, loss of 29.7%) were compared with a control group (N = 121 at baseline; 121 at 12 months and 113 at 24 months, loss of 9.3%), the nonintervention group. Variables included drinking frequency, quantity and peak consumption, dependence assessment, and family and friends' abuse assessment. Results: Treated students at a 24-month follow-up decreased quantity of alcohol use per occasion and lowered AUDIT and RAPI scores. Conclusions: This is the first brief intervention work on risky drinking with college students in Brazil and the results are encouraging. However, it is difficult to conduct individual prevention strategies in a country where culture fosters heavy drinking through poor public policy on alcohol and lack of law enforcement.

Characterization of S3Pvac Anti-Cysticercosis Vaccine Components: Implications for the Development of an Anti-Cestodiasis Vaccine

Background: Cysticercosis and hydatidosis seriously affect human health and are responsible for considerable economic loss in animal husbandry in non-developed and developed countries. S3Pvac and EG95 are the only field trial-tested vaccine candidates against cysticercosis and hydatidosis, respectively. S3Pvac is composed of three peptides (KETc1, GK1 and KETc12), originally identified in a Taenia crassiceps cDNA library. S3Pvac synthetically and recombinantly expressed is effective against experimentally and naturally acquired cysticercosis.Methodology/ Principal Findings: In this study, the homologous sequences of two of the S3Pvac peptides, GK1 and KETc1, were identified and further characterized in Taenia crassiceps WFU, Taenia solium, Taenia saginata, Echinococcus granulosus and Echinococcus multilocularis. Comparisons of the nucleotide and amino acid sequences coding for KETc1 and GK1 revealed significant homologies in these species. The predicted secondary structure of GK1 is almost identical between the species, while some differences were observed in the C terminal region of KETc1 according to 3D modeling. A KETc1 variant with a deletion of three C-terminal amino acids protected to the same extent against experimental murine cysticercosis as the entire peptide. on the contrary, immunization with the truncated GK1 failed to induce protection. Immunolocalization studies revealed the non stage-specificity of the two S3Pvac epitopes and their persistence in the larval tegument of all species and in Taenia adult tapeworms.Conclusions/ Significance: These results indicate that GK1 and KETc1 may be considered candidates to be included in the formulation of a multivalent and multistage vaccine against these cestodiases because of their enhancing effects on other available vaccine candidates.
