Varicose Veins and Chronic Venous Insufficiency in Brazil: Prevalence among 1755 Inhabitants of a Country Town

Abstract: The prevalence of varicose veins (VV) and of chronic venous insufficiency (CVI) was studied among 1755 adults over 15 years of age (443 men and 1312 women). These people attended the University Health Center in Botucatu, a country town in the State of Sao Paulo, Brazil, for routine examination or for any disease complaints. The prevalence of all grades of VV not including telangiectasis and reticular varices grade I was 47.6% (37.9% in men and 50.9% in non-pregnant women). The prevalence of VV recorded as moderate or severe was 21.2%. The more severe form of CVI with active or healed ulcer was present in 3.6% of the subjects (2.3% of men and 4% of women). For only 5.5% of the patients was VV or CVI the reason for medical consultation. The prevalence of VV increased with age and number of pregnancies and was greater among white than non-white people. Working posture or posture adopted for defaecation did not influence the prevalence of VV. Our data show the prevalence of VV and CVI to be higher or as high as the prevalence found in developed western countries. We therefore propose that studies of these conditions should be included in epidemiological surveys of other developing areas or countries, so that if data similar to ours are verified prophylaxis and early treatment could be included in health planning for these areas with the aim of reducing future morbidity and the related social onus.

Ulnar ray a/hypoplasia: evidence for a developmental field defect on the basis of genetic heterogeneity. Report of three Brazilian families

Abstract: We report on five Brazilian patients from three unrelated families with congenital anomalies of the upper limbs. Ulnar aplasia/hypoplasia was the main reason for examining these patients. Evidence for existence of an ulnar developmental field is based on genetic heterogeneity. Clinical and genetic aspects of the ulnar ray defects are discussed.

Delayed results of treatment of paracoccidioidomycosis with amphotericin B plus sulfamides versus amphotericin B alone

Atraves de analises estatisticas comprovam a maior eficacia do tratamento, quando se faz a manutencao com sulfamidicos.

Função pulmonar na evolução de 35 doentes com paracoccidioidomicose

Abstract: Lesoes pulmonares observadas na paracoccidioidomicose (pbmicose) pela radiologia foram designadas: leve, moderada e grave de acordo com criterio estabelecido pelos autores. Lesoes infiltrativas intersticiais bilaterais nddulo fibrolineares e cotonosas foram identificadas respectivamente em 34 e em 23 doentes. Formas leve, moderada e grave assinaladas respectivamente em 6 10 e 19 mostraram a analise radiologica evolutiva melhora em 2, piora em 15 e manutencao do padrao da lesao em 18 doentes. Testes de funcao pulmonar realizados nos doentes durante o retorno ambulatorial evidenciaram: 12 com padrao espirografico normal, 20 obstrutivos e 3 mistos; 34 doentes estavam hiperventilando e todos apresentaram aumento da diferenca alveolo arterial. Os resultados obtidos permitiram supor que a fibrose residual descrita nos padroes radiologicos; manutencao e piora de 33 deles aliada a doenca obstrutiva cronica verificada pelas provas de funcao pulmonar constituiram subsidios para o desenvolvimento do Cor pulmonale assinalado

Análise das condições de saúde e de vida da população urbana de Botucatu, SP: I - Descrição do plano amostral e avaliação da amostra

Abstract: Descreve-se o processo de amostragem para o levantamento das condicoes de saude e de vida da populacao urbana de Botucatu, SP (Brasil), pelo metodo de entrevistas domiciliarias. Analisa-se a representatividade da amostra, segundo a distribuicao percentual da populacao por estrato e segundo as variaveis sexo e idade. Comparam-se os criterios externos de estratificacao socio-economica com a renda familiar e per capita das familias entrevistadas. Comenta-se as dificuldades de operacionalizar o conceito de classe social atraves de zonas socio-espaciais, em investigacoes domiciliares e em estudos epidemiologicos que utilizam dados de registro rotineiros.

Relações entre fluxos de água subterrânea e superficial em bacia hidrográfica caracterizada por cobertura florestal amazônica.

Abstract: The investigation was carried out from May 1981 to december 1983 in a small hydrografic basin (area ca. 1,3 km2) drained by the stream "Βarrο Branco", situated in INPA's forest Reserve "Adolfο Ducke" (Highway AM 010, km 28).The area is covered by tropical rainforest of the amazonian "Terra firme" typo (i. e. situated above the levels of annual inundations).Stream discharge was 32,3%, interception by the canopy 22% and the remaining 45,7% fall on transpiration by the vegetation, thus resulting in a total of 67,7% evapotranspiration.Accordingly, one may expect significant changes in the water balance as a consequence of indiscriminate and massive deforestation, specifically reduced rainfall and a much higher percentage of stream discharge, accompanied by erosion and sedimentation.

Chromosome numbers and their taxonomic implications for eight Brazilian andropogons (Poaceae: Andropogoneae)

Abstract: Eleven chromosome counts are reported for Brazilian populations of eight species ofAndropogon. Counts for five of the species are first reports for the species. Four of these species,A. arenarius, A. glaziovii, A. lateralis, andA. lindmanii, are hexaploids (n=30) and belong to a group of about a dozen species informally referred to as theAndropogon lateralis complex. Two other species of this complex,A. bicornis andA. hypogynus, we also found to be hexaploids, in agreement with previous reports. Diploid counts (n=10) forA. macrothrix (a first report) andA. virgatus (the same as two previous reports) support the morphological affinities of these two species to other species complexes withinAndropogon.

Medicina caseira em sete localidades da região de Bauru, SP

Abstract: Este trabalho foi realizado nas localidades de Duartina, Piratininga, Presidente Alves, Bocaina, Boraceia, Dois Corregos e Potunduva (Regiao de Bauru), em 1981. O objetivo foi avaliar o conhecimento e o uso de plantas medicinais, pela populacao. Foram entrevistadas 372 pessoas, das quais, a maioria pertencia ao estrato social baixo. Mais de 95% das pessoas conheciam plantas medicinais, com grande utilizacao de duas a quatro variedades. O nao-uso representou, no total, apenas 10,8%. O local de obtencao mais frequente foi quintal, seguindo-se a farmacia. Citaram-se 118 plantas diferentes para uso medicinal Destas, em apenas 9,3% nao se encontrou, na literatura, o nome cientifico correspondente e, em 17,0%, a indicacao do valor medicinal O uso mencionado pelos entrevistados foi coincidente com os da literatura em quase 70% das vezes, em pelo menos um sintoma ou doenca. Discutiram-se as razoes do recente incremento da medicina caseira; alguns aspectos referentes a industrializacao e comercializacao de plantas medicinais e sublinhou-se a necessidade de promocao de pesquisas farmacologicas para o melhor conhecimento do valor terapeutico da flora medicinal brasileira.

Paracoccidioidomicose pulmonar agressiva, endotraqueíte estenosante e cor-pulmonale subagudo: descrição de um caso

Abstract: Paracoccidioidomycosis (Pbmycosis) reaches the lungs through the respiratory tract where it initiates the primary infection. Although the disease produces a variety of extrapulmonary manifestations, the lungs are involved in a large number of cases. The trachea is affected by Pbmycosis lymphohematogenic dissemination causing a granulomatous process leading to airway obstruction and secondary asphyxia. A 32 years old male, farm worker coming from Sarutaia (SP.) was studied in our hospital. The patient has developed, since 8 months ago a white productive daily cough and a mild dyspnea. Four months later, the mentioned symptoms worsened and anorexia and asthenia appeared. One month previously to hospital admission the dyspnea increased and a weight loss of 15 kg was observed. He has been a heavy smoker and a heavy drinker during the last 16 years. On physical examination it was observed: blood pressure = 100/70 mm/Hg, respiratory rate = 28 pm, body weight = 31 Kg. Pulmonary emphysema, clubbing, loud an splitting S2, right ventricular hypertrophy on E.K.G., hepatosplenomegaly and signs of obstructive pulmonary disease allowed the diagnosis of a "Cor pulmonale" — like syndrome, Amphotericin B was administred at the dose of 1 mg/Kg body weight. A relative adrenal insufficiency was observed early during the treatment. 45 days after hospitalization the patient developed an acute respiratory insufficiency caused by tracheal obstruction and aggravated Cor pulmonale. In spite of intensive care he died. The tracheal stenosis and sub acute Cor pulmonale reported in this patient is a rare manifestation of human pulmonary pbmycosis.

A comparative study of the immunoantigenicity of eight Paracoccidioides brasiliensis isolates

Abstract: The present study was carried out to investigate differences in the immunoantigenicity of 8 P. brasiliensis isolates from 3 endemic areas (Botucatu: Pb 1, 2 and 3; Sao Paulo: Pb 18, 192 and 265; Venezuela: Pb 9 and 73). The antigenic reactivity of each isolate in the indirect fluorescent test (II) and in the immunodiffusion test (ID) was studied using a panel of 20 positive control sera for paracoccidioidomycosis. The humoral (measured by immunodiffusion) and the cellular (measured by the footpad test) immune response inducing capacity of each isolate was assessed by the immunization of mice. It was observed: 1. Pb 265 and Pb 9 showed the highest reactivity in II; 2. Pb 192 and Pb 73 were the most reactive in ID; 3. These results demonstrate differences in antigenicity among these isolates; 4. Pb 18 exhibited weak cellular immune response inducing power and great capacity of evoking antiP. brasiliensis antibody production in the immunized mice showing dissociation of its immunogenicity. These differences may indicate the occurrence of strains of the fungus or may reflect modification of the parasite in the host or during culturing.

Dependence of the activity of grazing cattle on foraging grass‐cutting ants (Attn spp.) in the southern Neotropics

Abstract: In Paraguayan and Brazilian pastures with the grass-cutting ants, Atta bisphaerica, A. capiguara, A. laevigata and A. vollenweideri present, cattle were found to limit their grazing activity to areas in which grass-cutting ants were not actively cutting. Cattle confined to areas in which grass-cutting ants were actively cutting grazed significantly less and walked significantly more than cattle confined to areas free of cutting ants. Forage offered to cattle in which workers of grass-cutting ants were placed was consumed significantly less than control treatments, suggesting that the thoracic spines, which are well-developed in Atta spp., may be adaptive in the defense of vegetative resources against large mammalian herbivores, as well as serve other assumed adaptive functions. These results suggest that the impact of grass-cutting ants on Neotropical cattle production is much more complex than estimates of their grazing potential indicate. Zusammenfassung Abhangigkeit der Aktivitat von grasendem Vieh von grasschneidenden Ameisen (Atta spp.) im Suden der neotropischen Region Es wurden auf paraguayaischen und brasilianischen Weiden, die von den Grasschneider-Ameisen Atta bisphaerica, A. capiguara, A. laevigata und A. vollenweideri besiedelt waren, beobachtet, das das Vieh nur an solchen Stellen weitete, wo die Ameisen nicht aktiv waren. Wurden die Weidetiere gezwungen an Stellen zu grasen, wo Atta-Ameisen grasschneidend aktiv waren, frasen sie signifikant weniger und liefen mehr umher als Tiere an ameisenfreien Stellen. Dargereichtes Futter, in dem sich grasschneidende Ameisen belanden, wurden vom Vieh in geringen Mengen als ameisenfreies Futter angenommen. Dies deutet darauf hin, das die Atta-Ameisen ihren gut entwickelten Thorakal-Dorn zur Verteidigung des Grases gegen die herbivoren Sauger einsetzen. Die Ergebnisse zeigen, das die Wirkung grasschneidender Ameisen auf die Viehzuchtung der neotropischen Region uber die Verminderung der Grasmenge hinausgeht.

Influência do tamanho e umidade do grão na expansão da pipoca South American Mushroom

Abstract: Utilizando sementes do cultivar de milho-pipoca South American Mushroom, obtido em 1984/85 em Campinas, SP, procurou-se avaliar os efeitos do teor de umidade e tamanho de grao na expansao da pipoca. Foram empregados tamanhos de graos compreendidos entre as peneiras 14 e 18 e teores de umidade entre 9,4 e 19,8%. Os resultados mostraram que a capacidade de expansao foi maior nos graos menores e nos teores de umidade de 10,5 a 11,5%.

Antagonistic effect between histamine and norepinephrine on isolated guinea-pig right atrium.

Abstract: Norepinephrine (NE) and histamine (His) cause a dose related increase in the rate of the guinea pig isolated right atria. The rate increase induced by both amines has been shown to be mediated by pharmacologically different receptors. His shifted the NE CEC to the right in a non parallel fashion. Cimetidine (10(-4) mol/l) abolished this antagonism. Norepinephrine (3 X 10(-7) mol/l) shifted to the right the His CEC also in a non parallel fashion. Practolol (10(-4) mol/l) abolished this antagonism. Theophylline (10(-4) mol/l) reverted both: the antagonistic action of His related to the NE chronotropic effect and the antagonistic action of NE related to the His chronotropic effect. The reversal of the antagonism could be the result of the block of purinergic P1-receptors by theophylline. This block impairs the chronotropic effect of adenilic compounds which can function as a modulater of cardiac rate through a negative feed back mechanism.
