Análise das condições de saúde e de vida da população urbana de Botucatu, SP (Brasil): III - Conhecimentos e opiniões dos profissionais de saúde a respeito de sintomas de doenças, 1984

Foram estudados os conhecimentos e opiniões dos profissionais de saúde do Município de Botucatu, SP (Brasil), acerca da freqüência e gravidade de treze sintomas e sinais de doenças, visando à comparação com as opiniões emitidas pela população urbana do Município. Foram entrevistados 435 profissionais de saúde ativos (médicos, enfermeiros, auxiliares e atendentes de enfermagem e outros), a maioria do sexo feminino, com idade de 25 a 44 anos. A categoria de atendentes foi a mais numerosa. de modo geral, os cinco últimos sintomas da relação constante do formulário - sangue no escarro, sangramento vaginal, caroço no seio, acessos e sangue na urina, foram considerados menos freqüentes e mais graves, comparativamente aos oito primeiros: falta de ar, febre, fraqueza, dor nas costas, dor no peito, dor de cabeça, tosse e diarréia. Dentre as categorias, os médicos diferenciaram-se atribuindo, com menor freqüência, escores altos para a freqüência e gravidade. Os clínicos valorizaram mais do que os cirurgiões, esses dois fatores, para quase todos os sintomas. O cotejo com a opinião dos leigos entrevistados revelou semelhanças nas tendências, embora tenha havido, por parte destes, maior valorização da freqüência e gravidade.

Hepatic bleeding induced by streptokinase and heparin in a patient with acute myocardial infarction

Although rare, major bleeding is the most important side effect of thrombolytic therapy in acute myocardial infarction (AMI) (Levine et al., 1995). Spontaneous hepatic bleeding in normal liver after thrombolytic administration has rarely been reported in literature. To our knowledge, there are only three cases of hepatic bleeding related to thrombolytic therapy in AMI. In these, the used drugs were anisolylated plasminogen streptokinase activator complex (APSAC) (Garcia-Jiménez et al., 1997; Fox et al., 1991) and rt-PA (Garcia-Jiménez et al., 1997). We report a case of hepatic bleeding after streptokinase followed by units over 60 minutes). The next day, the patient developed third-degree atrioventricular block and a temporary pacemaker was inserted. Twenty-seven hours after streptokinase infusion, the patient complained of refractory chest pain that was interpreted as post-myocardial infarction angina; clotting screen was normal and intravenous heparin was started (80 U/kg followed by 18 U/kg/hour). After four hours of heparin administration, the patient presented abdominal pain and distension, and his blood pressure and hematocrit level dropped. Abdominal ultrasonography revealed free fluid in the peritoneal cavity (about 3,000 mL). A laparotomy disclosed blood in the abdominal cavity with bleeding from the right lateral hepatic segment, which was removed. The remaining abdominal viscera were normal and there was no other evidence of hemorrhage. The partial liver resection presented subcapsular hemorrhage with small parenchymal hemorrhage. Histopathological examination also revealed focal areas of ischemic centrilobular necrosis. The patient died of multiple organ system failure 21 days after admission.

Acute coronary syndrome associated with continuous 5-fluorouracil infusion in a patient with metastatic colorectal cancer-a case report with a discussion on this clinical dilemma

Introduction: 5-Fluorouracil (5-FU) is considered to be the backbone of colorectal cancer (CRC) systemic therapy since the great majority of recommended regimens include its administration. A clinical picture consisting of chest pain, sometimes cardiac enzyme elevation, electrocardiogram abnormalities consistent with myocardial ischemia, and normal coronary angiogram associated with 5-FU administration have been infrequently reported. The clinical dilemma is: Which chemotherapy regimen should we use in CRC patients with a previous acute coronary syndrome (ACS) associated with 5-FU? Case Report: We describe the case of a 55-year-old otherwise healthy woman with metastatic colon adenocarcinoma who presented an ACS probably secondary to arterial vasospasm while receiving continuous intravenous 5-FU infusion (mFOLFOX6 regimen). After the ACS, the patient was treated with raltitrexate plus oxaliplatin (TOMOX) and subsequently with irinotecan plus cetuximab with no other cardiac event. Conclusion: The risk of cardiotoxicity associated with 5-FU is low but real. The probable mechanism is arterial vasospasm, as suggested by our case report. Both the use of the TOMOX regimen and irinotecan plus cetuximab seems to be safe regimens to be considered in this clinical scenario. © 2009 Humana Press Inc.

Estudo clínico, morfológico e imuno-histoquímico de série de casos de tuberculose pleural e ganglionar

A dificuldade no diagnóstico definitivo da tuberculose extrapulmonar persiste principalmente devido a baixa resolutividade dos métodos convencionais disponíveis para a detecção do Mycobacterium tuberculosis. Esse estudo teve como objetivos avaliar a contribuição da técnica imuno-histoquímica (IHQ) para a detecção de Mycobacterium spp. em casos de tuberculose pleural e ganglionar com histoquímica negativa, assim como, investigar alguns aspectos clínicos, laboratoriais e morfológicos da doença. Para obtenção desta amostra fez-se a busca dos casos no Núcleo de Vigilância Epidemiológica (NVE) e Divisão de Arquivo Médico e Estatística (DAME) do Hospital Universitário João de Barros Barreto (HUJBB) e no Departamento de Anatomia Patológica da Universidade Federal do Pará (UFPA), selecionando-se aqueles que haviam realizado exame histopatológico para esclarecimento diagnóstico do caso. Foram incluídos 50 pacientes, sendo 25 com diagnóstico presuntivo de tuberculose pleural e 25 de tuberculose ganglionar. Para obtenção dos dados clínicos e laboratoriais os respectivos prontuários foram revisados, e para confirmação dos aspectos morfológicos foi realizada a revisão de todas as lâminas selecionadas. Posteriormente, cada amostra foi submetida à técnica IHQ com anticorpo polyclonal Mycobacterium bovis BCG. Encontrou-se no grupo investigado, maior frequência do sexo masculino, cuja média de idade foi de 33,8 anos (desvio padrão: 14,1) sendo a maioria procedente da cidade de Belém-Pará e com nível de escolaridade de sete ou menos anos de estudo. Os sintomas constitucionais mais frequentes em todo o grupo foram a febre e perda ponderal. Nos pacientes com tuberculose pleural, os sintomas específicos mais encontrados foram tosse, dor torácica e dispneia, e naqueles com a forma ganglionar da doença, o envolvimento da cadeia cervical isolada foi mais frequente. Infecção pelo vírus da imunodeficiência humana (HIV) ou Síndrome da Imunodeficiência Adquirida (Sida) e etilismo foram as condições de risco mais frequentemente associadas. Na tuberculose pleural, 20% dos casos cursaram com derrame pleural associado à lesão parenquimatosa, e em 60% o líquido pleural foi do tipo exsudativo. Enquanto, na forma ganglionar, em 50% dos casos evidenciou-se lesão parenquimatosa à radiografia do tórax. Neste estudo, foi inexpressiva a quantidade de participantes nos quais foi realizada a pesquisa direta e cultura para bacilo álcool - ácido resistente (BAAR) nos diversos espécimes clínicos analisados (líquido pleural, tecido pleural e ganglionar, escarro e lavado broncoalveolar) O padrão morfológico predominante em ambas as formas da doença foi o granuloma tipo tuberculoide com necrose caseosa, independente do status sorológico para o HIV. A técnica IHQ contribuiu para o diagnóstico de tuberculose pleural em 21% (4/19) das amostras de tecido pleural e em 37,5% (9/24) de tecido ganglionar. Um resultado imuno-histoquímico positivo define o diagnóstico de micobacteriose, e quando associado aos achados clínicos, laboratoriais e morfológicos torna-se uma ferramenta de grande utilidade para melhorar o diagnóstico da tuberculose extrapulmonar.

Possible adverse drug events leading to hospital admission in a Brazilian teaching hospital

OBJECTIVES: Drug safety problems can lead to hospital admission. In Brazil, the prevalence of hospitalization due to adverse drug events is unknown. This study aims to estimate the prevalence of hospitalization due to adverse drug events and to identify the drugs, the adverse drug events, and the risk factors associated with hospital admissions. METHOD: A cross-sectional study was performed in the internal medicine ward of a teaching hospital in São Paulo State, Brazil, from August to December 2008. All patients aged ≥18 years with a length of stay ≥24 hours were interviewed about the drugs used prior to hospital admission and their symptoms/complaints/causes of hospitalization. RESULTS: In total, 248 patients were considered eligible. The prevalence of hospitalization due to potential adverse drug events in the ward was 46.4%. Overprescribed drugs and those indicated for prophylactic treatments were frequently associated with possible adverse drug events. Frequently reported symptoms were breathlessness (15.2%), fatigue (12.3%), and chest pain (9.0%). Polypharmacy was a risk factor for the occurrence of possible adverse drug events. CONCLUSION: Possible adverse drug events led to hospitalization in a high-complexity hospital, mainly in polymedicated patients. The clinical outcomes of adverse drug events are nonspecific, which delays treatment, hinders causality analysis, and contributes to the underreporting of cases.

Diagnosis and management of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is probably one of the most prevalent diseases in the world that also compromises the quality of life of the affected significantly. Its incidence in Brazil is 12%, corresponding to 20 million individuals. OBJECTIVE: To update the GERD management and the new trends on diagnosis and treatment, reviewing the international and Brazilian experience on it. METHOD: The literature review was based on papers published on Medline/Pubmed, SciELO, Lilacs, Embase and Cochrane crossing the following headings: gastroesophageal reflux disease, diagnosis, clinical treatment, surgery, fundoplication. RESULTS: Various factors are involved on GERD physiopathology, the most important being the transient lower esophageal sphincter relaxation. Clinical manifestations are heartburn, regurgitation (typical symptoms), cough, chest pain, asthma, hoarseness and throat clearing (atypical symptoms), which may be followed or not by typical symptoms. GERD patients may present complications such as peptic stenosis, hemorrhage, and Barrett's esophagus, which is the most important predisposing factor to adenocarcinoma. The GERD diagnosis must be based on the anamnesis and the symptoms must be evaluated in terms of duration, intensity, frequency, triggering and relief factors, pattern of evolution and impact on the patient's quality of life. The diagnosis requires confirmation with different exams. The goal of the clinical treatment is to relieve the symptoms and surgical treatment is indicated for patients who require continued drug use, with intolerance to prolonged clinical treatment and with GERD complications. CONCLUSION: GERD is a major digestive health problem and affect 12% of Brazilian people. The anamnesis is fundamental for the diagnosis of GERD, with special analysis of the typical and atypical symptoms (duration, intensity, frequency, triggering and relief factors, evolution and impact on the life quality). High digestive endoscopy and esophageal pHmetry are the most sensitive diagnosctic methods. The clinical treatment is useful in controlling the symptoms; however, the great problem is keeping the patients asymptomatic over time. Surgical treatment is indicated for patients who required continued drug use, intolerant to the drugs and with complicated forms of GERD.

Validation of the Short-Version of Rose Angina Questionnaire in Brazil

Background: Stable angina pectoris is a serious condition with few epidemiological studies in Brazil. Objective: To validate the short-version of the Rose angina questionnaire in Brazilian Portuguese for its implementation in surveys and longitudinal studies. Methods: A total of 116 consecutive patients from an outpatient clinic without prior myocardial infarction and/or coronary revascularization were enrolled for application of three questions of the Rose angina questionnaire addressing chest pain after exertion. We used the treadmill test as the gold standard with the Ellestad protocol. Results: The short-version of the Rose angina questionnaire of the 116 subjects submitted to the exercise treadmill test disclosed 89.7% of accuracy, 25% of sensitivity, 92.0% of specificity, 10.0% of positive predictive value, 97.2% of negative predictive value, and 3.1 of positive likelihood ratio and 0.82 of negative likelihood ratio. Conclusion: The Portuguese version with three items of the Rose angina questionnaire is suitable for epidemiological purposes. (Arq Bras Cardiol 2012; 99(5): 1056-1059)

Inactive Disease and Remission in Childhood-Onset Systemic Lupus Erythematosus

Objective. To define inactive disease (ID) and clinical remission (CR) and to delineate variables that can be used to measure ID/CR in childhood-onset systemic lupus erythematosus (cSLE). Methods. Delphi questionnaires were sent to an international group of pediatric rheumatologists. Respondents provided information about variables to be used in future algorithms to measure ID/CR. The usefulness of these variables was assessed in 35 children with ID and 31 children with minimally active lupus (MAL). Results. While ID reflects cSLE status at a specific point in time, CR requires the presence of ID for >6 months and considers treatment. There was consensus that patients in ID/CR can have <2 mild nonlimiting symptoms (i.e., fatigue, arthralgia, headaches, or myalgia) but not Raynaud's phenomenon, chest pain, or objective physical signs of cSLE; antinuclear antibody positivity and erythrocyte sedimentation rate elevation can be present. Complete blood count, renal function testing, and complement C3 all must be within the normal range. Based on consensus, only damage-related laboratory or clinical findings of cSLE are permissible with ID. The above parameters were suitable to differentiate children with ID/CR from those with MAL (area under the receiver operating characteristic curve >0.85). Disease activity scores with or without the physician global assessment of disease activity and patient symptoms were well suited to differentiate children with ID from those with MAL. Conclusion. Consensus has been reached on common definitions of ID/CR with cSLE and relevant patient characteristics with ID/CR. Further studies must assess the usefulness of the data-driven candidate criteria for ID in cSLE.

BNP and Admission Glucose as In-Hospital Mortality Predictors in Non-ST Elevation Myocardial Infarction

Objectives. Admission hyperglycemia and B-type natriuretic peptide (BNP) are associated with mortality in acute coronary syndromes, but no study compares their prediction in-hospital death. Methods. Patients with non-ST-elevation myocardial infarction (NSTEMI), in-hospital mortality and two-year mortality or readmission were compared for area under the curve (AUC), sensitivity (SEN), specificity (SPE), positive predictive value (PPV), negative predictive value (NPV), and accuracy (ACC) of glycemia and BNP. Results. Respectively, AUC, SEN, SPE, PPV, NPV, and ACC for prediction of in-hospital mortality were 0.815, 71.4%, 84.3%, 26.3%, 97.4%, and 83.3% for glycemia = 200 mg/dL and 0.748, 71.4%, 68.5%, 15.2%, 96.8% and 68.7% for BNP = 300 pg/mL. AUC of glycemia was similar to BNP (P = 0.411). In multivariate analysis we found glycemia >= 200mg/dL related to in-hospital death (P = 0.004). No difference was found in two-year mortality or readmission in BNP or hyperglycemic subgroups. Conclusion. Hyperglycemia was an independent risk factor for in-hospital mortality in NSTEMI and had a good ROC curve level. Hyperglycemia and BNP, although poor in-hospital predictors of unfavorable events, were independent risk factors for death or length of stay >10 days. No relation was found between hyperglycemia or BNP and long-term events.

Acute coronary syndromes in young patients: Presentation, treatment and outcome

Background: Acute coronary syndromes (ACS) in very young patients have been poorly described. We therefore evaluate ACS in patients aged 35 years and younger. Methods: In this prospective cohort study, 76 hospitals treating ACS in Switzerland enrolled 28,778 patients with ACS between January 1, 1997, and October 1, 2008. ACS definition included ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI), and unstable angina (UA). Results: 195 patients (0.7%) were 35 years old or younger. Compared to patients N35 years, these patients were more likely to present with chest pain (91.6% vs. 83.7%; P=0.003) and less likely to have heart failure (Killip class II to IV in 5.2% vs. 23.0%; Pb0.001). STEMI was more prevalent in younger than in older patients (73.1% vs. 58.3%; Pb0.001). Smoking, family history of CAD, and/or dyslipidemia were important cardiovascular risk factors in young patients (prevalence 77.2%, 55.0%, and 44.0%). The prevalence of overweight among young patients with ACS was high (57.8%). Cocaine abuse was associated with ACS in some young patients. Compared to older patients, young patients were more likely to receive early percutaneous coronary interventions and had better outcome with fewer major adverse cardiac events. Conclusions: Young patients with ACS differed from older patients in that the younger often presented with STEMI, received early aggressive treatment, and had favourable outcomes. Primary prevention of smoking, dyslipidemia and overweight should be more aggressively promoted in adolescence.

The prevalence of endothelial dysfunction in patients with and without coronary artery disease

Endothelial dysfunction (ED) is frequently present in patients presenting with acute or stable coronary artery disease (CAD), but it is also found in patients presenting with chest pain without angiographic coronary lesions.

Thoraxschmerzen bei Kindern und Jugendlichen - das Herz?

Chest pain in children and adolescents is a frequent observation, although potentially relevant disease is rather rare and then found in situations with acute presentation. In children with an inflammatory/infectious clinical context the differential diagnosis is oesophagitis, pleuropneumonia or pericarditis. Potentially dangerous complications may be found in youth with predisposing conditions for aortic dissection, pneumothorax or pulmonary embolism, or even in rare instances for an acute coronary complication. In these cases aggressive diagnostic work-up is mandatory. In the frequent elective outpatient evaluation of teenagers with long-lasting episodes of chest pain, relevant underlying cardiovascular disease only rarely can be found as the cause. In the elective outpatient evaluation for chest pain, usually patient history and clinical examination may be enough to track the problem, the main role of the physician is to provide reassurance with minimal but appropriate testing.

Impact of left ventricular hypertrophy late after aortic valve replacement for aortic stenosis on cardiovascular morbidity and mortality

AIMS: The goal of this study was to assess the prevalence of left ventricular (LV) hypertrophy in patients with aortic stenosis late (>6 months) after aortic valve replacement and its impact on cardiac-related morbidity and mortality. METHODS AND RESULTS: In a single tertiary centre, echocardiographic data of LV muscle mass were collected. Detailed information of medical history and angiographic data were gathered. Ninety-nine of 213 patients (46%) had LV hypertrophy late (mean 5.8 +/- 5.4 years) after aortic valve replacement. LV hypertrophy was associated with impaired exercise capacity, higher New York Heart Association dyspnoea class, a tendency for more frequent chest pain expressed as higher Canadian Cardiovascular Society class, and more rehospitalizations. 24% of patients with normal LV mass vs. 39% of patients with LV hypertrophy reported cardiac-related morbidity (p = 0.04). In a multivariate logistic regression model, LV hypertrophy was an independent predictor of cardiac-related morbidity (odds ratio 2.31, 95% CI 1.08 to 5.41), after correction for gender, baseline ejection fraction, and coronary artery disease and its risk factors. Thirty seven deaths occurred during a total of 1959 patient years of follow-up (mean follow-up 9.6 years). Age at aortic valve replacement (hazard ratio 1.85, 95% CI 1.39 to 2.47, for every 5 years increase in age), coexisting coronary artery disease at the time of surgery (hazard ratio 3.36, 95% CI 1.31 to 8.62), and smoking (hazard ratio 4.82, 95% CI 1.72 to 13.45) were independent predictors of overall mortality late after surgery, but not LV hypertrophy. CONCLUSIONS: In patients with aortic valve replacement for isolated aortic stenosis, LV hypertrophy late after surgery is associated with increased morbidity.
