Cirurgia ambulatorial em proctologia: análise retrospectiva de 437 casos

RACIONAL: O número de cirurgias ambulatoriais realizadas em hospitais, como em clínicas particulares, cresce a cada dia. Hoje, em alguns países, como a França, há predomínio das cirurgias ambulatoriais em relação às hospitalares. OBJETIVO: Avaliar retrospectivamente os pacientes operados no Serviço de Cirurgia Ambulatorial do Hospital das Clínicas da Faculdade de Medicina de Botucatu, SP. CASUÍSTICA E MÉTODO: Foram estudados retrospectivamente 437 casos clínicos de patologias orificiais, analisando a distribuição por faixa etária, por sexo, por patologias e as complicações pós-operatórias. RESULTADOS: Notou-se predomínio de pacientes com idade inferior a 45 anos (62,8%), prevalência do sexo feminino (56%), sendo a doença hemorroidária (45,1%) a principal patologia e a dor e sangramento as complicações mais freqüentes (9,8% e 7,3%). CONCLUSÕES: Os resultados satisfatórios observados demonstram a possibilidade de realização, em ambulatório, de diversos procedimentos simples em patologias anorretais freqüentes, a baixo custo e poucas complicações, sendo estas não superiores às observadas em cirurgia hospitalar.

Artificial oocyte activation using calcium ionophore in ICSI cycles with spermatozoa from different sources

The present study evaluated the effect of artificial oocyte activation (AOA) with calcium ionophore A23187 oil intracytoplasmic sperm injection (ICSI) cycles using spermatozoa from different sources. The 314 cycles evaluated were divided into three groups according to sperm origin, the ejaculated group (n = 92), the epididymal group (n = 82). and the testicular roup (n = 140). Each group was further split into experimental subgroups, depending oil whether or no AOA was performed. In additions the cycles of women younger than 36 years were evaluated separately. For each experimental group, ICSI outcomes were compared between subgroups. No significant difference was observed between subgroups for all sperm origin groups. When evaluating only the cycles of women younger than 36 years of age, AOA increased the percentage of high-quality embryos (74.5 versus 53.0%. P = 0.011) and the implantation rate (19.3 versus 10.5%, P = 0.0025) when it was used with ejaculated spermatozoa, and the percentage of high-quality embryos (64.4 versus 50.3%, P = 0.006) when epididymal spermatozoa were used. These results may suggest that both sperm maturity and oocyte quality play a role in oocyte activation. However. this study is to be continued to confirm these findings.

Violência entre parceiros íntimos e álcool: prevalência e fatores associados

Objective. To estimate physical violence between intimate partners and to examine the association between violence and sociodemographic variables, use of alcohol, and other related factors.Method. This epidemiologic survey included a stratified probabilistic sample representative of the population from the city of São Paulo in economic and educational terms. The Gender, Alcohol and Culture: An International Study (GENACIS) questionnaire was employed. The sampling unit was the home, where all individuals older than 18 years were candidates for interview. The final sample included 1 631 people. Statistical analysis employed the Rao Scott test and logistic regression.Results. The response rate was 74.5%. Most participants were female (58.8%), younger than 40 years of age (52%), or had 5 to 12 years of schooling. of the overall group, 5.4% reported having been victims of physical violence by an intimate partner and 5.4% declared having been aggressors of intimate partners in the past 2 years. Most men declared that none of those involved had ingested alcohol at the moment of aggression. Most women reported that nobody or only the man had drunk. Being a victim or an aggressor was associated with younger age and having a heavy-drinking partner. Women suffered more serious aggression, requiring medical care, and expressed more anger and disgust at aggression than men.Conclusions. The results underscore the importance of the association between alcohol use and risk of aggression between intimate partners, and may contribute to the design of public policies aimed to control this situation.

Ocorrência de anticorpos anti-Neospora caninum em cães da microrregião da Serra de Botucatu, Estado de São Paulo, Brasil

Neosporose é uma enfermidade parasitária causada pelo protozoário Neospora caninum reconhecido como importante causa de abortamento bovino e neuropatia canina. Considerando o isolamento de N. caninum e a sorologia freqüente em bovinos em nossa região, os objetivos do presente trabalho foram avaliar a ocorrência de anticorpos anti-N. caninum em cães da Microrregião da Serra de Botucatu, Estado de SãoPaulo, e sua associação ao sexo, idade e procedência quanto à zona urbana (exclusivamente cidade), rural (somente chácaras e sítios) e peri-urbana (acesso à zona urbana e rural) dos cães estudados. Foram analisados 963 cães, com ou sem raça definida, de ambos os sexos e diferentes idades, sem apresentação de qualquer sintomatologia clínica. Os animais foram selecionados aleatoriamente durante a campanha de vacinação anti-rábica da microrregião da Serra de Botucatu, no período de maio a setembro de 1998. O soro obtido dos animais foi avaliado por meio da Reação de Imunofluorescência Indireta (RIFI) utilizando como antígeno a cepa padrão NC-1 deN. caninum. Observaram-se 245 animais reagentes (25,4% de positividade), sendo 161 (27,5%) machos e, 84 (22,3%) fêmeas. Dos animais de zona urbana, rural e mista 223 (25,8%),11(16,9%) e 11(33,3%), respectivamente, foram reagentes à prova de RIFI. Todos os 11 municípios apresentaram cães soropositivos com valores de ocorrência que variaram de 8,9% a 53,5%. Observou-se percentual de positividade menor em cães até um ano (16,2%) quando comparados àqueles entre 1 a 4 anos e superior a 4 anos (28,4 % e 28,0%, respectivamente) que não apresentaram diferença entre si. Os resultados obtidos caracterizaram soropositividade para N. caninum em cães pertencentes a todos os municípios da Microrregião da Serra de Botucatu evidenciando a ampla distribuição do agente na região.

Relação entre o índice de massa corporal e a gravidade da asma em adultos

OBJETIVO: O aumento do índice de massa corporal (IMC) tem sido associado a uma maior prevalência da asma em adultos. O presente estudo tem o objetivo de avaliar a associação entre a prevalência da obesidade e a gravidade da asma. MÉTODOS: Prontuários de duzentos asmáticos acima dos 20 anos de idade foram avaliados retrospectivamente. A asma foi classificada quanto à gravidade através da história clínica e do diagnóstico registrados, dos resultados da espirometria e da medicação prescrita. O IMC foi calculado e foram considerados obesos os pacientes com IMC > 30 kg/m². RESULTADOS: 23% dos pacientes apresentavam asma intermitente, 25,5%, asma persistente leve, 24%, asma persistente moderada e 27,5%, asma persistente grave. O IMC < 29,9 kg/m² foi observado em 68% dos pacientes e em 32% o IMC foi > 30 kg/m². O odds ratio da relação entre a obesidade e a gravidade da asma foi de 1,17 (CI95%: 0,90-1,53; p > 0,05). CONCLUSÕES: Na amostra estudada não foi encontrada correlação entre a obesidade e a gravidade da asma nem no sexo masculino, nem no feminino.

Estudo comparativo de fatores de risco em crianças e adolescentes com diagnóstico antropométrico de sobrepeso ou obesidade

OBJETIVO: O excesso de peso é um grande problema de saúde pública em todo o mundo, atingindo crianças e adolescentes. O presente estudo teve por objetivo verificar se a condição de portador de sobrepeso se associa à presença de fatores de risco à saúde. MÉTODOS: Foram estudados 84 sujeitos entre seis e 17 anos, constituindo-se um grupo de 34 pacientes portadores de sobrepeso e outro de 50 obesos, atendidos em ambulatório de Nutrologia Pediátrica da Universidade de Ribeirão Preto (Unaerp), durante o período de outubro de 2004 a outubro de 2005. Foram obtidas as variáveis: pressão arterial, circunferência abdominal, glicemia de jejum, glicemia de segunda hora, colesterol total, HDL-c, LDL-c e triglicérides. Comparam-se os dois grupos por meio de duas abordagens estatísticas: comparação entre as distribuições dos valores absolutos (teste de Mann-Whitney) e entre as frequências de valores considerados alterados (teste exato de Fisher). RESULTADOS: Quanto à primeira abordagem, verificou-se diferença estatística apenas para o HDL-c, com maiores valores para o subgrupo de portadores de sobrepeso de seis a dez anos. Quanto à segunda comparação, verificou-se diferença estatística para a circunferência abdominal (segundo os critérios de Freedman), HDL-c e glicemia de jejum, com maiores frequências de valores alterados entre os obesos. CONCLUSÕES: Os portadores de sobrepeso apresentaram alterações indicativas de prejuízos à sua saúde, semelhantemente aos obesos, sendo necessário também incluí-los nos programas de prevenção e tratamento.

Idade materna como fator de risco: estudo com primigestas na faixa etária igual ou superior a 28 anos

Trata-se de estudo transversal, cujo objetivo foi analisar a idade materna como fator de risco ou não, através da verificação de intercorrências na gestação, parto e puerpério de primigestas com idade igual ou superior a 28 anos e das condições de nascimento e alta de seus recém-nascidos, comparando-as com o grupo de primigestas na faixa etária de 20 a 27 anos. Foi realizado em Botucatu/S.P., no período de janeiro de 1990 a junho de 1995. A análise estatística, discutida ao nível de 5% de significância, foi realizada através da prova de Mann-Whitney, teste de Goodman e avaliação do risco relativo e risco relativo corrigido, através da técnica de Mantel-Haenszel. Concluiu-se que a idade materna igual ou superior a 28 anos não constituiu fator de risco gestacional, puerperal e intra-parto mas, por outro lado, foi fator de risco, mesmo após controlado o tipo de parto, para as seguintes intercorrências perinatais: taquipnéia transitória do recém-nascido, cianose generalizada ao nascer e infecção neonatal.

Antibodies to Neospora caninum and Toxoplasma gondii in domestic cats from Brazil

The occurrence of antibodies to Neospora caninum and Toxoplasmagondii was determined in 400 domestic cats (Siamese, Persian, and undetermined breeds) from the Municipality of Aracatuba, São Paulo, Brazil, through the indirect fluorescence antibody test (IFAT). of the 400 cats, 100 were seropositive to T. gondii (25%, titer >= 64) and 98 to N. caninum (24.5%, titer >= 16). The rate of seropositive cats for T. gondii was correlated with age (chi(2)=35.7; p < 0.001), with a higher number of infected animals at older ages. of the 219 cats younger than 1-year-old, 13.2% were seropositive for T. gondii, while 39.2% were positive in the 181 older animals. The presence of N. caninum was also correlated with age (divided by(2)=8.8; p < 0.01), with 18.7% (41/219) and 31.5% (57/181) of positive animals at ages below and above 12-month, respectively. An association between the occurrences of both protozoa in the felines was also observed (chi(2)=19.6; p < 0.001).

Periodontal status in smokers and never-smokers: Clinical findings and real-time polymerase chain reaction quantification of putative periodontal pathogens

Background: Smoking is a well-known risk factor for destructive periodontal disease, but its relationship with periodontal status and subgingival microbiota remains unclear. Inherent limitations of microbiological methods previously used may partly explain these mixed results, and real-time polymerase chain reaction (PCR) has been presented as a valid alternative. The aim of the present study was to investigate the clinical condition and microbiological profile of patients with chronic periodontitis as related to the habit of smoking.Methods: Fifty patients (33 to 59 years old), 25 smokers and 25 never-smokers, constituted the sample. The visible plaque index (VPI), gingival bleeding index (GBI), bleeding on probing (BOP), periodontal probing depth (PD), clinical attachment loss (CAL), and gingival crevicular fluid (GCF) volume were recorded. Real-time PCR quantified Porphyromonas gingivalis, Micromonas micros, Dialister pneumosintes, Actinobacillus actinomycetemcomitans and total bacteria in subgingival samples.Results: Smokers and never-smokers showed similar values for VPI, GBI, and BOP. Smokers had deeper PD in buccal/lingual sites and higher CAL independently of the tooth surface. The GCF volume was smaller in smokers, independent of the PD. Similar amounts of total bacteria and P. gingivalis were observed for both groups. Significantly higher numbers of D. pneumosintes and M. micros were present in smokers and associated with moderate and deep pockets. When heavy smokers were considered, higher counts of total bacteria, M. micros, and D. pneumosintes were observed.Conclusions: Smoking seems to have a detrimental impact on the periodontal status and microbiological profile of patients with periodontitis. Compared to never-smokers, smokers had deeper pockets, greater periodontal destruction, and higher counts of some putative periodontal pathogens.

Landfills as risk factors for respiratory disease in children

Objective: To investigate the relationship between exposure to a landfill site closed 6 years previously and respiratory symptoms in children aged up to 13 years.Method: This was a cross-sectional study conducted in Varzea Paulista, in the state of São Paulo, Brazil. One adult in every household in a neighborhood close to the landfill and from a randomized sample of households in another neighborhood with similar socioeconomic characteristics but no landfill were interviewed and asked about respiratory symptoms and other variables relating to children aged up to 13. A logistic regression model was used to study this relationship.Results: The likelihood of a child having respiratory symptoms was a function of -2.36 + 0.43 if the child was less than 2 years old; + 0.24 if the child lived in the landfill area; -0.67 if there was a computer at home; + 0.54 if firewood was burnt in the home in the last year; + 0.94 if the child was diagnosed with asthma; + 0.87 if the child visited a health service in the previous 30 days.Conclusion: The authors conclude that living near to a landfill closed 6 years previously may be a risk factor for respiratory disease in children.

Prácticas de alimentación complementaria en niños dentro del primer año de vida

This study aimed to investigate complementary feeding practices during children's first year of life in Botucatu, SP, Brazil. Practices were described according to the age range and the breastfeeding (BF) practice. Data were collected during a multi-vaccination campaign through the interview of 1,238 individuals who accompanied children younger than one year old being vaccinated. Differences associated with the BF situation were identified by the chi-square test and Fisher's exact test. The early introduction of complementary food was observed, which led to the low frequency of exclusive breastfeeding (36.9% <4 months). Children younger than 4 months old consumed tea (30.7%); children between 4 and 6 months old consumed fruits (54.1%), soups (39.9%) and home-made food (19.2%). Juice was offered only to 15.2% of children younger than 4 months old who were completed weaned, 60% of the children was offered water. Data show that the consistence of the food consumed was inappropriate: children between 6 and 8 months old were offered the family's regular food (48.8%) and children older than 8 months (71.6%) were offered soup. Therefore, interventions focused on complementary feeding are justified on the city.

Contribuição do uso de medicamentos para a admissão hospitalar

According to the Word Health Organization, adverse drug reactions (ADR) are any harmful and non intentional answer which occurred in doses normally used in human beings. The ADR can be responsible for 2.4% to 11.5% of hospital admissions. Therefore, this study aimed at knowing the admitted patient's demographic profile due to possible ADR, identifying the most frequent drugs and complaints, and evaluating the incidence of hospital admission related to drug use. Patients who were 18 years old or more and were admitted during a period of one month to a medical clinical of a general hospital were interviewed for one month about drug use before being admitted, as well as regarding to the complaint which led them to hospital. These information were analyzed according to official data, like MICROMEDEX® and WHO criteria as well. It was observed that the admission due to drug use occurred in most part of the cases in elderly [47.5% (66/139)] and women [62% (87/139)]. The most frequent drugs used were: omeprazole (16), analgesics (31), antihypertensive (31), simvastatin (7) and formoterol fumarate (6), and the symptoms were normally associated to the digestive (20.5%), circulatory (20.2%), respiratory (18.2%) and central nervous systems (13.9%). It was estimated that 15.5% (139/897) of the hospital admission occurred possibly due to the drug use. The data found by present study suggests some strategies in order to prevent ADR in the context of primary health care services, such as monitoring drug therapy, manly for patients with chronic diseases, elderly and polimedicated people; and pharmaceutical care including dispensation and purchasing of the drugs, a lot of them dispensed over the counter (OTC).
