Manejo da dor inguinal crônica pós-hernioplastia (inguinodinia)

A dor inguinal crônica pós-herniorrafia é uma situação preocupante, pois aproximadamente 10% dos pacientes submetidos à hernioplastia inguinal apresenta os sintomas, que com frequência limita a capacidade física. A etiopatogênese está relacionada a uma periostite do púbis (dor somática) e mais frequentemente à lesão nervosa (dor neuropática). É importante distinguir clinicamente entre os dois tipos de dor, pois o tratamento pode ser diferente. O médico deve estabelecer uma rotina diagnóstica e de tratamento, sendo que a maior parte dos pacientes necessitarão de terapêutica cirúrgica. A prevenção desta condição é de grande importância e pode levar a uma menor incidência da síndrome. Algumas medidas são fundamentais, como evitar pontos ou clipes no periósteo do púbis, usar criteriosamente as próteses e identificar os nervos da região inguinal. Esta última medida é certamente a mais importante na prevenção da dor crônica e implica em conhecimento profundo da anatomia e o uso de uma técnica aprimorada.

Culturally-sensitive complaints of depressions and anxieties in women

Background: Current classifications of Mental Disorders are centered on Westernized concepts and constructs. Cross-cultural sensitivity emphasizes culturally-appropriate translations of symptoms and questions, assuming that concepts and constructs are applicable.Methods: Groups and individual psychiatrists from various cultures from Asia, Latin America, North Africa and Eastern Europe prepared descriptions of main symptoms and complaints of treatment-seeking women in their cultures, which are interpreted by clinicians as a manifestation of a clinically-relevant dysphoric disorder. They also transliterated the expressions of DSM IV criteria of main dysphoric disorders in their cultures.Results: In many non-western cultures the symptoms and constructs that are interpreted and treated as dysphoric disorders are mostly somatic and are different from the Western-centered DSM or ICD systems. In many cases the DSM and ICD criteria of depression and anxieties are not even acknowledged by patients.Limitations: the descriptive approach reported here is a preliminary step which involved local but Westernized clinicians-investigators following a biomedical thinking. It should be followed by a more systematic-comprehensive surveys in each culture.Conclusions: Westernized concepts and constructs of mental order and disorders are not necessarily universally applicable. Culturallysensitive phenomena, treatments and treatment responses may be diversified. Attempts at their cross-cultural harmonization should take into consideration complex interactional multi-dimensional processes. (c) 2006 Elsevier B.V. All rights reserved.

Quadro clínico do transtorno obsessivo-compulsivo

Obsessive-compulsive disorder is a very heterogeneous condition, not always easy to be identified. Obsessions are intrusive thoughts, impulses or images that cause anxiety or other emotional discomfort, whereas compulsions are repetitive behaviors or mental acts voluntarily performed to counterbalance or minimize the discomfort, or magically prevent any feared events. The most common symptoms are contamination, aggressive, somatic and sexual obsessions and washing, checking, repeating, counting and ordering compulsions. Patients usually have multiple symptoms simultaneously, which often change over time. Although the insight is typically preserved, it varies among patients and also fluctuates in the same patient in different ocasions. The main features are: exacerbated appraisal of risks, pathological doubts and incompleteness, as well as excessive sense of responsibility and guilt and thought/action fusion. As patients frequently feel ashamed of their symptoms, they can be reticent about them. Consequently, it usually takes time till they get adequate treatment.

PSA and androgen-related gene (AR, CYP17, and CYP19) polymorphisms and the risk of adenocarcinoma at prostate biopsy

The aim of the present study was to examine the impact of polymorphisms in prostate-specific antigen (PSA) and androgen-related genes (AR, CYP17, and CYP19) on prostate cancer (PCa) risk in selected high-risk patients who underwent prostate biopsy. Blood samples and prostate tissues were obtained for DNA analysis. Single-nucleotide polymorphisms in the 50-untranslated regions (UTRs) of the PSA (substitution A > G at position -158) and CYP17 (substitution T > C at 50-UTR) genes were detected by polymerase chain reaction (PCR)-restriction fragment length polymorphism assays. The CAG and TTTA repeats in the AR and CYP19 genes, respectively, were genotyped by PCR-based GeneScan analysis. Patients with the GG genotype of the PSA gene had a higher risk of PCa than those with the AG or AA genotype (OR = 3.79, p = 0.00138). The AA genotype was associated with lower PSA levels (6.44 +/- 1.64 ng/mL) compared with genotypes having at least one G allele (10.44 +/- 10.06 ng/mL) (p = 0.0687, 95% CI - 0.3146 to 8.315, unpaired t-test). The multivariate analysis confirmed the association between PSA levels and PSA genotypes (AA vs. AG+GG; chi(2) = 0.0482) and CYP19 (short alleles homozygous vs. at least one long allele; chi(2) = 0.0110) genotypes. Genetic instability at the AR locus leading to somatic mosaicism was detected in one PCa patient by comparing the length of AR CAG repeats in matched peripheral blood and prostate biopsy cores. Taken together, these findings suggest that the PSA genotype should be a clinically relevant biomarker to predict the PCa risk.

Aspectos citológicos e microbiológicos do leite em propriedades no sistema orgânico de produção

A produção de leite no sistema orgânico tem despertado o interesse dos produtores rurais, pelo aumento de consumo de produtos naturais. Estudaram-se os aspectos citológicos e microbiológicos do leite no sistema orgânico de produção em quatro propriedades no município de Botucatu, SP, utilizando métodos como CMT, exame microbiológico das amostras positivas, contagem de células somáticas (CCS/mL de leite) e Contagem de Unidades Formadoras de Colônias (UFC de microrganismos mesófilos/mL de leite) em amostras individuais de leite em animais com pelo menos um teto positivo ao CMT. Foi também realizado a CCS/mL de leite e UFC/mL de leite, e exame microbiológico de amostras de leite do conjunto (tanque) de cada propriedade. Das 150 glândulas mamárias examinadas, 66 (44,00%) amostras foram positivas ao CMT, com isolamento de Corynebacterium bovis em 37,90%, Staphylococcus aureus (18,20%), S. epidermidis (15,20%), Streptococcus uberis (3,00%) e S. dysgalactiae (3,00%), e isolamento de mais de um agente bacteriano em 7,60% das amostras. Os valores de CCS/mL das amostras do leite de conjunto estiveram dentro dos limites de normalidade em três das quatro propriedades (< 400x10³), por outro lado considerando a UFC/mL em três das quatro propriedades observou-se altos índices (8,5x10(5); 1,5x10(6); 4,1x10(5)). Obteve-se o isolamento de microrganismos ambientais, como Escherichia coli e Pseudomonas aeruginosa, sugerindo a contaminação do leite durante ou após a ordenha, o que reforça a importância de atividades de educação sanitária para obtenção higiênica do leite.

H19-DMR allele-specific methylation analysis reveals epigenetic heterogeneity of CTCF binding site 6 but not of site 5 in head-and-neck carcinomas: A pilot case-control analysis

Aberrant methylation of seven potential binding sites of the CTCF factor in the differentially methylated region upstream of the H19 gene (H19-DMR) has been suggested as critical for the regulation of IGF2 and H19 imprinted genes. In this study, we analyzed the allele-specific methylation pattern of CTCF binding sites 5 and 6 using methylationsensitive restriction enzyme PCR followed by RFLP analysis in matched tumoral and lymphocyte DNA from head-and-neck squamous cell carcinoma (HNSCC) patients, as well as in lymphocyte DNA from control individuals who were cancer-free. The monoallelic methylation pattern was maintained in CTCF binding site 5 in 22 heterozygous out of 91 samples analyzed. Nevertheless, a biallelic methylation pattern was detected in CTCF binding site 6 in a subgroup of HNSCC patients as a somatic acquired feature of tumor cells. An atypical biallelic methylation was also observed in both tumor and lymphocyte DNA from two patients, and at a high frequency in the control group (29 out of 64 informative controls). Additionally, we found that the C/T transition detected by HhaI RFLP suppressed one dinucleotide CpG in critical CTCF binding site 6, of a mutation showing polymorphic frequencies. Although a heterogeneous methylation pattern was observed after DNA sequencing modified by sodium bisulfite, the biallelic methylation pattern was confirmed in 9 out of 10 HNSCCs. These findings are likely to be relevant in the epigenetic regulation of the DMR, especially in pathological conditions in which the imprinting of IGF2 and H19 genes is disrupted.

Estudo comparativo entre a acepromazina, clorpromazina e levomepromazina em diferentes doses, através do exame bispectral, termo e pressoalgimetria, em cães

The study's objective was to realize comparisons among different acepromazine, chlorpromazine and methotrimeprazine doses, evaluate parametric changes, test analgesia using press and term algimetry, and evaluate bispectral condition. 90 mongrel dogs were used, male and female, adult, weighting 10 to 15 Kg as a rule, distributed in 9 groups with 10 animals each. At first, second and third groups acepromazine was used at 0,1; 0,05 e 0,025 mg/Kg, respectively. At forth, fifth and sixth groups, chlorpromazine was used at 1,0; 0,5 and 0,25 mg/Kg, respectively. At seventh, eighth and ninth groups, methotrimeprazine at 1,0; 0,5 and 0,25 mg/Kg was used, respectively. All drugs were administered intravenously. objects of study: heart rate (HR), non invasive blood pressure (SAP, MAP, DAP), respiratory rate (f), capnography (ETCO(2)), pulse oxymetry (SatO(2)), mouth and rectal temperature, bispectral index (BIS), electromyography (EMG%), press and term algimetry. Somatic analgesia was evaluated by animal's response to nociceptives stimulus. We concluded that chlorpromazine had more bypotension. Dogs showed higher hypnosis level at: chlorpromazine group, with evident myorelaxation. All groups showed analgesia to thermic and mechanic stimulus. Acepromazine group showed high duration to both pain stimuli. Bispectral index was shorten at chlorpromazine group at 1,0 mg/kg doses, showing higher hypnosis index, and acepromazine was the less depressing considering the bispectral index.

Avaliação da produção de leite e contagem de células somáticas em bovinos leiteiros suplementads com Saccharomyces cerevisiae como fonte de zinco orgânico

The aim of the evaluation of milk production and somatic cell count of dairy cow supplemented with Saccharomyces cerevisiae as a source of organic zinc for 180 days, 25 Holstein cows were selected, randomly chosen from a flock of 189 lactating cows. The animals were distributed in two groups, namely group 1 (G1) which holded 10 cows supplemented and group 2 (G2) with 15 animals without supplementation. The production of milk was measured by the control official milkman of the Assocition Paranaense of Creators of Bovine of the Holstein in seven moments during the 180 days. The samples of milk were collected of each animal, being submitted to the electronic counting of somatic cells. The results demonstrate that the supplemented of organic zinc didn't alter the production of milk, however it was capable to maintain low the counting of somatic cells. The data of the present work suggest that to use supplemented of organic zinc in the diet of cows milk, increase the quality of the produced milk and consequently the remuneration for the producer.

Associação deagentes patogênicos isolados emanálise microbiológica da água, coma presença de mastite clínica ou subclínica, em vacas de propriedades leiteiras da região de Cerqueira César - SP

Objetivou-se, neste trabalho, pesquisar a relação entre os microrganismos patogênicos isolados e identificados em água utilizada na ordenha, com o isolamento e identificação dos mesmos em amostras de leite, de quartos mamários apresentando mastite clínica ou subclínica nas mesmas propriedades. Foram utilizadas 16 propriedades rurais leiteiras, escolhidas aleatoriamente, na região de Cerqueira César - SP, que utilizavam ordenha mecânica. A água utilizada na ordenha foi classificada em relação à presença de coliformes totais e fecais, como dentro dos padrões ou fora dos padrões de potabilidade humana. Nos resultados obtidos, 94% das amostras foram classificadas como fora dos padrões em relação a coliformes totais e fecais. Os microrganismos identificados foram: Escherichia coli (51%), Enterobacter spp. (25%), Enterobacter cloacae (8%) Edwardsiella tarda (8%) e Klebsiella oxytoca (8%). em relação ao leite, foram analisadas 373 amostras provenientes de vacas em lactação, com mastite clínica (n=19; 5%) e subclínica (n=354; 95%). Os animais com mastite subclínica foram identificados pela contagem de células somáticas (CCS), utilizando-se o aparelho eletrônico (Somacount 300, Bentley), onde a média observada foi de 1.631 x 10³ células/mL. Os principais microrganismos identificados foram: Staphylococcus aureus (30%), Corynebacterium bovis (23%) e Staphylococcus spp. (15%). Conforme os dados obtidos, os agentes coliformes encontrados na água, utilizada na ordenha, não estavam presentes nas análises das amostras de leite dos quartos mamários com mastite clínica ou subclínica das respectivas propriedades, demonstrando não haver associação entre a qualidade da água e a ocorrência de mastite.

Surto de mastite bovina causada por Arcanobacterium pyogenes

An uncommon outbreak of mastitis caused by Arcanobacterium pyogenes in 26 cows is reported. The epidemiological findings, clinical signs, microbiological exams, somatic cell count, in vitro susceptibility profile of strains, efficacy of intramammary treatment and control measures were discussed. Florfenicol (96.2%), cefoperazona (92.3%), cefaloxin (84.6%) and ceftiofur (84.6%) were the most effective antimicrobials, and neomicin (27.0%) and enrofloxacin (17.4%) the least effective antimicrobials.

Breed and season influence on milk quality parameters and in mastitis occurrence

Os objetivos do presente estudo foram avaliar a performance das raças Jersey e Holandesa em diferentes condições de pluviosidade (estações seca e chuvosa) através do monitoramento de aspectos relacionados com a mastite subclínica (contagem de células somáticas, isolamento microbiológico, tipo de patógeno isolado), qualidade do leite (lactose, proteína, gordura e sólidos totais) e produção (media da produção de leite) de ambas as raças. O estudo foi conduzido em propriedade leiteira localizada no estado de São Paulo, Brasil. Oito visitas foram realizadas a propriedade, quatro em período de alta pluviosidade e outro em período de baixa pluviosidade. Amostras de leite foram colhidas de todos os animais para contagem eletrônica de células somáticas e determinação dos principais componentes do leite (proteína, gordura, sólidos totais, lactose). Gordura, proteína, sólidos totais e produção leiteira foram influenciadas tanto pela raça como pela estação, apresentando tendências similares para ambas raças em ambas estações. A contagem de células somáticas (CCS) apresentou resultados similares para ambas as raças. Vacas holandesas com infecção intramamária (IIM) apresentaram um maior aumento na CCS quando comparadas as vacas Jersey (P<0.001). Na estação seca, 53 animais tiveram IIM em pelo menos um mês do estudo. Destes, 32 eram da raça Holandesa e 21 da raça Jersey. Na estação chuvosa, 65 animais possuíram infecção intramamária, dos quais 43 eram da raça Holandesa e 22 da raça Jersey. A frequência de casos de IIM foi maior na estação chuvosa em comparação à estação seca. Vacas Jersey apresentaram uma menor chance de desenvolver sinais e sintomas de IIM em relação às vacas holandesas na estação chuvosa (razão de chances=0.52). O maior numero de casos de IIM na estação chuvosa pode ter contribuído para uma menor taxa de lactose no leite para ambas as raças, sendo que esta pode ser considerada como um indicador do status de IIM. Existiu uma prevalência de patógenos contagiosos durante todo o experimento. O modelo estatístico aplicado mostrou que patógenos ambientais foram mais frequentemente isolados da raça Jersey, independentemente do período do estudo. Aparentemente existem diferenças na resposta imune das raças Jersey e Holandesa.

Estudo dos métodos de rotina diagnóstica de mastite no leite de éguas

Routine diagnosis methods used in bovine mastitis were studied in 55 mares in lactation. The findings of strip cup test, California Mastitis Test-CMT, electronic somatic cell count-CCS, microbiological culture, and in vitro antimicrobial susceptibility profile of isolates were discussed. Streptococcus spp., Staphylococcus spp, and enterobacteria were the most common microorganisms isolated in health and CMT-positive mammary glands. Staphylococcus aureus and Arcanobacterium pyogenes were identified in two mares presenting clinical mastitis. Mean somatic cell count of eight mares without presence of microorganisms in milk was 247.57x10³/mL and 1.621,86x10³/mL in 47 mares with positive microbiological culture. Moderate concordance (63.8%) between positive reactions in CMT (1 to 3+) and microbiological culture was observed. Amicacin (78.9%), ceftiofur (74.7%), sulpha-trimetoprim (69,0%) and norfloxacin (69.0%), were the most effective drugs, while resistance of isolates was mainly observed against penicillin (64.8%), gentamycin (35.2%), azithromycin (35.2%), enrofloxacin (28.2%), and florfenicol (28.2%).

Relationship between teat-end condition, udder cleanliness and bovine subclinical mastitis

The aims of the present study were to relate intramammary infection (IMI) occurrence and somatic cell count (SCC) with teat-end condition (TEC) and udder cleanliness (UC). Milk samples from 1931 teats were evaluated according to the presence of IMI and SCC. Scores were applied to teats according to the TEC and to UC. Teats ends with a very rough ring had the largest number of IMI when compared to the other three categories, as well as animals with dirtier udders. The change in a TEC score increased by around 30% the chance of IMI. Also, the chance of the animal developing IMI increased by approximately 47% when the UC score increased. No significant association between both scores and quarter SCC was found. It can be concluded that animals with very rough teat end rings and very dirty udders have a greater predisposition to IMI.
