A luta de classes em Portugal (1919:1926) : a esquerda republicana e o bloco radical

Com o presente trabalho estudamos a Primeira República do pós-guerra (1919-1926), procurando compreender o sentido histórico desses anos atribulados, caracterizados por uma permanente instabilidade governativa e pelo desassossego dos agentes sociais. Defendemos existir uma explicação que torna os últimos anos do regime republicano, aparentemente caóticos, compreensíveis: à semelhança de outros países europeus, a especificidade dos anos 20 portugueses reside num fenómeno de polarização política da sociedade, na mobilização e organização de forças mediante os quadrantes da esquerda e da direita modernas. Concretamente, o nosso objecto de estudo consiste na esquerda republicana, um campo que se autonomizou dentro do republicanismo durante o pós-guerra, e no bloco radical, conceito analítico sob o qual englobamos manifestações heteróclitas (partidárias, armadas, intelectuais, unitárias) do fenómeno de polarização política à esquerda.

Envelhecimento, memória e estímulo cognitivo

Neste artigo apresentamos uma breve revisão da literatura sobre o papel da memória no processo de envelhecimento e a deterioração que esta sofre em caso de demência, por exemplo de Alzheimer. Expomos ainda um ensaio/programa de treino cognitivo para estimular/reabilitar a memória. O aumento acentuado da esperança de vida, associado à baixa natalidade que se vem observando na maioria dos países ocidentais, poderá fazer com que as manifestações psicopatológicas da terceira idade se tornem bastante incidentes. Torna-se portanto indispensável que o envelhecimento decorra de forma natural, saudável, simplificando o funcionamento do organismo e libertando-o de problemas indesejáveis. Com o presente artigo procuramos alertar a comunidade para o tema do envelhecimento, da consequente diminuição de capacidades cognitivas, funcionais e executivas, fazendo um especial enfoque à memória.

Trans-cultural aspects of social anxiety disorder and related conditions: a Brazilian case series and a review of international clinical studies

Cross-cultural studies have much to teach clinicians and researchers alike about psychopathology in general and about social anxiety disorder (SAD) in particular. Unfortunately, little is known about the degree and the mechanisms through which cultural environment may influence clinical manifestations of SAD. OBJECTIVE: Our objective was to identify culture-related clinical patterns in SAD and related disorders. METHODS: We described socio-demographic and clinical characteristics of a sample of 62 adult outpatients with SAD seen at a university clinic for anxiety and depressive disorders in Rio de Janeiro, Brazil, and compared them with those reported in clinical samples from North America, Europe, Asia and Oceania identified through a systematic review in Medline, PsychINFO, and LILACS. RESULTS: Our comparison of trans-cultural features of SAD lends partial support to Heimberg's (1997) contention that the majority of socio-demographic features and symptoms of this disorder are relatively independent of geographic and cultural differences. CONCLUSION: Patients with SAD were almost universally characterized by: 1) a predominance of males in clinical samples; 2) early onset of the disorder; 3) high educational attainment; and 4) great frequency of comorbidities.

Topical tropicamide induced delirium and psychosis: case report

Acute psychosis and confusional states are known complications of treatment with anticholinergic agents in the elderly. We report an 87-year-old female patient presenting with acute neurobehavioral abnormalities requiring hospitalization immediately after starting treatment for openangle glaucoma with the topic cycloplegic muscarinic receptor blocker tropicamide. Case-effect relationship was confirmed. The authors make a review of the literature trying to identify the clinical manifestations and risk factors for this complication.

Psychosis associated with methimazole-induced hypothyroidism: a case report

INTRODUCTION: Thyroid dysfunction has often been associated with several psychiatric manifestations. Previous case reports/series suggest the possible role played by acute alteration of thyroid status in the onset of psychotic symptoms. METHODS: Case report and literature review. RESULTS: A 45-year-old woman with no psychiatric antecedents was brought to the ER with a full-blown psychotic episode, marked by paranoid delusions, which developed gradually over two months. She had been treated elsewhere for hyperthyroidism for five years with methimazole 40 mg/d, with poor compliance. One month before the beginning of the psychotic symptoms, methimazole was raised to 60 mg/d and she started taking it correctly. Five months earlier she had TSH: 0.074 uUI/ml and free T4: 1.3 ng/dl. At admission we found a diffuse thyroid goiter, TSH: 70.9 uUI/ml and free T4: 0.03 ng/dl. Brain CT was normal. We hospitalized her with the diagnosis of a psychosis secondary to hypothyroidism, suspended methimazole, and gave her levothyroxine (up to 75 µg/d) and risperidone (2 mg/d). The patient had a quick remission and was discharged after 15 days. Within one month she had TSH: 0.7 uUI/ml and was completely recovered psychiatrically. She has been well since then, with risperidone in the first 8 months, and without it for 10 months now. CONCLUSION: This case report is a reminder of the necessity of checking thyroid status as part of clinical assessment of psychoses. It also supports the hypothesis that antithyroid drugs may have severe psychiatric consequences, especially when they lead to an acute change of thyroid status.

Neoplastic pericardial disease. Analysis of 26 patients

PURPOSE: To characterize patients with neoplastic pericardial disease diagnosed by clinical presentation, complementary test findings, and the histological type of tumor. METHODS: Twenty-six patients with neoplastic pericardial disease were retrospectively analyzed. RESULTS: Clinical manifestations and abnormalities in chest roentgenograms and electrocardiograms were frequent, but were not specific. Most patients underwent surgery. There was a high positivity of the pericardial biopsy when associated with the cytological analysis of the pericardial liquid used to determine the histological type of the tumor, particularly when the procedure was performed with the aid of pericardioscopy. CONCLUSION: The correct diagnosis of neoplastic pericardial disease involves suspicious but nonspecific findings during clinical examination and in screen tests. The suspicious findings must be confirmed through more invasive diagnostic approaches, in particular pericardioscopy with biopsy and cytological study.

Natural course of subsequent pregnancy after peripartum cardiomyopathy

OBJECTIVE: To assess the effect of subsequent pregnancy after peripartum cardiomyopathy (PPCM) on maternal and fetal outcome. METHODS: Prospective study of 34 patients with the diagnosis of PPCM (mean age= 26years). At the time of first diagnosis 5 were in NYHA functional class (FC) II for heart failure, one in FC III and 28 in FC IV. After clinical treatment, patients were advised to avoid new pregnancies and a follow-up was obtained. RESULTS: There were 12 (35.3%) subsequent pregnancies in patients (pt) aged 19 to 44 years (mean 32), divided into two groups: GI: 6 pts who had normalized their heart size and GII: 6 pts with persistent cardiomegaly. GI had initially mild clinical manifestations ( 3 were in FC II, 1 in FC II and 2 in FC IV) and complete recovery of cardiac function (FC I). A new pregnancy was well-tolerated in 5 (83.3%); 1 pt presented with preeclampsia, and progressed to FC II. Presently, 5 pt are in FC I and 1 in FC II. GII pts had more severe heart failure at the onset of PPCM (1 pt in FC II and 5 in FC IV); during follow-up, 4 pt were in FC I and 2 in FC II. A new pregnancy was well tolerated in all of them, but the eldest, who had had 2 pregnancies and had a progressive worsening of clinical status, dying 8 years after the last pregnancy and 13 years after the diagnosis of PPCM. The remaining 5 pt are still alive, 3 in FC I and 2 in FC II, with worsening of FC in 1. Subsequent pregnancies occurred 3-7 years after clinical treatment of PPCM and no fetal distress was observed. CONCLUSION: Subsequent pregnancies are well-tolerated after PPCM, but not devoid of risk. No fetal distress was observed. A minimum interval of 3 years after the recovery of function seems to be safe for subsequent pregnancies.

Cardiac abnormalities in the acquired immunodeficiency syndrome. A prospective study with a clinical-pathological correlation in twenty-one adult patients

OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males). ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42%) and dilated cardiomyopathy (19%). Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

Cardiac involvement in total generalized lipodystrophy (Berardinelli- Seip syndrome)

Total generalized lipodystrophy (Berardinelli--Seip Syndrome) is a rare hereditary disease characterized by insulin-resistant diabetes mellitus and a small quantity of adipose tissue and is of unknown origin. Common cardiovascular alterations related to this syndrome are cardiac hypertrophy and arterial hypertension. This article reports a case of Berardinelli--Seip syndrome and reviews the literature with special emphasis on the cardiovascular manifestations of this syndrome.

Cardiac extension of primary mediastinal seminoma compressing the right ventricular outflow tract

We report the case of a 33-year-old male with primary seminoma of the anterior mediastinum with initial clinical manifestations suggestive of heart disease.

Pneumococcal endocarditis of subacute evolution

With the development of penicillin, Streptococcus pneumoniae has become an uncommon cause of bacterial endocarditis in adults. Subacute manifestation of pneumococcal endocarditis has been reported a few times in the literature, but most reports define the disease as acute, severe, and having a high mortality rate. We report the case of a 58-year-old male with subacute bacterial endocarditis due to Streptococcus pneumoniae. We stress the low frequency of this agent as a cause of endocarditis and the atypical evolution of this case. The pathophysiology, clinical manifestations and evolution, and the therapeutical options for this type of infection are also discussed.

Electrocardiographic Alterations in Patients Hospitalized with Leptospirosis in the Brazilian City of Salvador

OBJECTIVE: To report the frequency and types of electrocardiographic alterations in patients with leptospirosis in the first 24 hours of hospitalization. METHODS: We analyzed the electrocardiograms of 157 patients admitted to the Hospital Couto Maia in the city of Salvador, in the State of Bahia, Brazil, from March 1998 to June 1999. The electrocardiograms were performed in the first 24 hours after hospital admission, independent of the clinical manifestations of the patients. RESULTS: The mean ± SD for patients' age was 35.5± 13.7 (median = 32) years, and jaundice was present in 95.5% of them. Alterations in the electrocardiogram were detected in 68.2% (107/157) of the patients (95% confidence interval = 60.6% - 75.1%). Atrial fibrillation was the most frequent arrhythmia, occurring in 10.8% (17/157) of the patients. Other frequent findings were alterations in ventricular repolarization detected in 38.9% (61/157) of patients and first-degree atrioventricular block in 10.2% (16/157). The patients with atrial fibrillation were older and had higher levels of creatinine and aminotransferases. CONCLUSION: In this sample, approximately 2/3 of the patients had electrocardiographic alterations after hospital admission. Of the major arrhythmias, atrial fibrillation was the most frequent, and the patients with this arrhythmia had evidence of more severe disease. The relation between the presence and type of electrocardiographic alteration and the prognosis of leptospirosis is yet to be assessed.
