Automedicação em adultos de baixa renda no município de São Paulo

OBJETIVO: Estimar a proporção de automedicação em adultos de baixa renda e identificar fatores associados. MÉTODOS: Foram utilizados dados de inquérito populacional realizado no município de São Paulo em 2005, cujo plano amostral incluiu dois domínios, favela e não favela, com amostragem por conglomerados em dois estágios, totalizando 3.226 indivíduos elegíveis. Além de características sociodemográficas e econômicas, foram analisados: uso de medicamentos nos 15 dias anteriores à entrevista, tipo de acesso (gratuito, comprado ou outra) aos medicamentos e os tipos de morbidades (crônicas ou agudas) tratadas, em análise de regressão logística múltipla. RESULTADOS: A proporção de automedicação foi de 27% a 32%. Automedicação esteve fortemente associada à morbidade aguda, ao acesso ao medicamento por compra, à idade menor que 47 anos e medicamentos do grupo terapêutico que atuam no sistema nervoso central. O grupo que atua no sistema nervoso central foi o mais utilizado na automedicação. CONCLUSÕES: O acesso gratuito aos medicamentos mostrou-se fator de proteção para a automedicação. A distribuição de medicamentos e o atendimento adequado devem ser considerados para orientação e redução dos riscos que o uso irracional de medicamentos pode gerar à saúde.

Transvaginal US after Bowel Preparation for Deeply Infiltrating Endometriosis: Protocol, Imaging Appearances, and Laparoscopic Correlation

Deeply infiltrating endometriosis (DIE) is a common gynecologic disease that is characterized by a difficult and delayed diagnosis. Radiologic mapping of the DIE lesion sites is crucial for case management, patient counseling, and surgical planning. Transvaginal ultrasonography (US) is the initial imaging modality for investigating DIE and has been the focus of several recent studies. DIE typically manifests at imaging as hypoechogenic nodules throughout the affected sites and thickening of the intestinal wall, with some lesions showing a mixed pattern due to cystic areas. Transvaginal US performed after bowel preparation improves the ability to diagnose intestinal lesions and provides invaluable details, including which layers of the intestine are affected and the distance between the lesion and the anal border. It is vital that radiologists be familiar with the technical aspects of this modality and with the US manifestations of DIE lesions. Transvaginal US performed after bowel preparation should be the first-line imaging modality for the evaluation of women with suspected endometriosis. (C) RSNA, 2010 . radiographics.rsna.org

Findings of Pelvic Endometriosis at Transvaginal US, MR Imaging, and Laparoscopy

Endometriosis is a common multifocal gynecologic disease that manifests during the reproductive years, often causing chronic pelvic pain and infertility. It may occur as invasive peritoneal fibrotic nodules and adhesions or as ovarian cysts with hemorrhagic content. Although findings at physical examination may be suggestive, imaging is necessary for definitive diagnosis, patient counseling, and treatment planning. The imaging techniques that are most useful for preoperative disease mapping are transvaginal ultrasonography (US) after bowel preparation, and magnetic resonance (MR) imaging. Initial transvaginal US is a reliable technique for detecting rectosigmoid endometriotic lesions. MR imaging is indicated as a complementary examination in complex cases of endometriosis with extensive adhesions and ureteral involvement. Peritoneal endometriotic implants are typically hypoechoic on transvaginal US images and demonstrate low signal intensity on T2-weighted MR images. Endometriotic implants most commonly are found in retrocervical and rectosigmoid sites, followed by the vagina, bladder, and ureters. Cysts with low-level internal echoes and echogenic peripheral foci at transvaginal US are suggestive of endometriomas. MR imaging has high specificity for identifying endometriomas, which are characterized by high signal intensity on T1-weighted images and low signal intensity on T2-weighted images. Correlation of the radiologic imaging features of endometriotic lesions with their laparoscopic appearances may help improve individual proficiency in the radiologic diagnosis of endometriosis.

Sexual satisfaction among patients with erectile dysfunction treated with counseling, sildenafil, or both

Introduction. Sexual satisfaction is linked to life satisfaction, and erectile dysfunction (ED) may lead to an impaired quality of life (QOL). Aim. Our goal was to evaluate the QOL among Brazilian patients with ED, before and after three kinds of treatment. Methods. Men aged 25-55 years, with a diagnosis of psychogenic or mixed ED, according to the Classification of Mental and Behavioral Disorders of the International Classification of Diseases, 10th edition, and the Standard Practice in Sexual Medicine, were randomly assigned to three treatment groups: counseling, sildenafil, and sildenafil plus counseling. At baseline each group had 40 patients. Sildenafil was provided in 50 mg that could be adjusted to 100 mg. The patients could initially take one to two tablets per week and the entire treatment lasted for 3 months. Counseling was provided in group sessions that took place once a week. They were evaluated at baseline and after 3 months of treatment with the Male Sexual Quotient (MSQ) and the Sexual Health Inventory for Men (SHIM). Main Outcome Measures. The correlation between the patients` MSQ score and scores on the SHIM. Results. One hundred seventeen patients were enrolled. The three groups were similar according to age, marital status, mean time of ED, and ED severity and etiology. At baseline, MSQ and SHIM total scores were not different among the three groups. MSQ scores increased from 41.2 +/- 15.3, 38.7 +/- 18.0, and 46.8 +/- 17.0 to 48.5 +/- 15.3, 63.8 +/- 21.6, and 70.0 +/- 17.3 after counseling, sildenafil, and sildenafil plus counseling, respectively (P < 0.05). SHIM scores also increased significantly (9.6 +/- 4.1, 9.7 +/- 4.1, and 10.2 +/- 3.9 to 12.1 +/- 3.9, 16.7 +/- 5.6, and 17.7 +/- 4.5 after counseling, sildenafil, and sildenafil plus counseling, respectively) (P < 0.05). There were no serious adverse events related to sildenafil, and no patient was withdrawn from the study because of an adverse event. Conclusions. The three treatments were significantly efficient, and the best treatment was sildenafil associated with counseling.

Oral findings and dental care in a patient with myelomeningocele: case report of a 3-year-old child

Myelomeningocele (MMC) is a congenital malformation of the neural tube that occurs in the first weeks of pregnancy. This malformation refers to the caudal non-closure of the neural tube and neural tissue exposure, which lead to neurological problems, such as hydrocephalus, motor disability, genitourinary tract and skeletal abnormalities and mental retardation. Patients with MMC have an acknowledged predisposition to latex allergy and are usually at a high caries risk and activity due to poor oral hygiene, fermentable carbon hydrate-rich diet and prolonged use of sugar-containing medications. This paper addresses the common oral findings in pediatric patients with MMC, discusses the strategies and precautions to deal with these individuals and reports the dental care to a young child diagnosed with this condition.

Leishmania spp. parasite isolation through inoculation of patient biopsy macerates in interferon gamma knockout mice

Isolation of Leishmania parasite and species identification are important for confirmation and to help define the epidemiology of the leishmaniasis. Mice are often used to isolate pathogens, but the most common mouse strains are resistant to infection with parasites from the Leishmania (Viannia) subgenus. In this study we tested the inoculation of interferon gamma knockout (IFNγ KO) mice with biopsy macerates from Leishmania-infected patients to increase the possibility of isolating parasites. Biopsies from twenty five patients with clinical signs of leishmaniasis were taken and tested for the presence of parasites. Immunohistochemical assay (IHC) and conventional histopathology detected the parasite in 88% and 83% of the patients, respectively. Leishmania sp. were isolated in biopsy macerates from 52% of the patients by culture in Grace's insect medium, but 13% of isolates were lost due to contamination. Inoculation of macerates in IFNγ KO mice provides isolation of parasites in 31.8% of the biopsies. Most isolates belong to L. (Viannia) subgenus, as confirmed by PCR, except one that belongs to L. (Leishmania) subgenus. Our preliminary results support the use of IFNγ KO mice to improve the possibility to isolate New World Leishmania species.

Estimating HIV-1 incidence using the serologic testing algorithm for recent HIV infections at HIV counseling and testing centers in the city of São Paulo, Brazil

The network of HIV counseling and testing centers in São Paulo, Brazil is a major source of data used to build epidemiological profiles of the client population. We examined HIV-1 incidence from November 2000 to April 2001, comparing epidemiological and socio-behavioral data of recently-infected individuals with those with long-standing infection. A less sensitive ELISA was employed to identify recent infection. The overall incidence of HIV-1 infection was 0.53/100/year (95% CI: 0.31-0.85/100/year): 0.77/100/year for males (95% CI: 0.42-1.27/100/year) and 0.22/100/ year (95% CI: 0.05-0.59/100/year) for females. Overall HIV-1 prevalence was 3.2% (95% CI: 2.8-3.7%), being 4.0% among males (95% CI: 3.3-4.7%) and 2.1% among females (95% CI: 1.6-2.8%). Recent infections accounted for 15% of the total (95% CI: 10.2-20.8%). Recent infection correlated with being younger and male (p = 0.019). Therefore, recent infection was more common among younger males and older females.

A importância da intervenção nutricional na redução do peso corpóreo em pacientes com síndrome do anticorpo antifosfolípide

OBJETIVO: Avaliar a eficácia da intervenção nutricional na redução do excesso de peso (EP), em pacientes com síndrome do anticorpo antifosfolípide (SAF). MÉTODO: Incluídos 40 pacientes, acima de 18 anos, com diagnóstico de SAF primária ou secundária, acompanhados no Serviço de Reumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (HC-FMUSP) e recrutados no período de outubro de 2005 a fevereiro de 2006. Foram coletados dados demográficos e realizados a revisão de prontuários, a mensuração de peso e da altura, o cálculo do índice de massa corpórea (IMC) atual e a adequação da dieta pelo IMC ideal. Foi realizada avaliação na primeira consulta e após intervalo mínimo de dois meses. RESULTADOS: A média de idade dos pacientes foi de 41 anos, sendo 93% de mulheres. Os pacientes com SAF primária perfaziam 25%, com média de dois anos da doença. A trombose venosa ocorreu em 63%, arterial em 48% e manifestações obstétricas em 27%. Na primeira consulta, 68% apresentavam EP, 27% eram eutróficos e 5% estavam com baixo peso (BP). Após três meses de intervenção, os eutróficos mantiveram o peso e os de BP tornaram-se eutróficos, segundo o IMC. Interessantemente, entre os pacientes com EP (n = 27), 82% emagreceram, 14% engordaram e 4% se mantiveram. Especificamente, 11 pacientes apresentaram 1% a 3% de perda ponderal de peso, oito perderam de 4% a 7%, dois reduziram 8% a 9% e um reduziu 13,6% com o acompanhamento nutricional. CONCLUSÃO: Foi demonstrado no presente estudo que a intervenção nutricional conseguiu atingir metas para redução de peso, possibilitando diminuição no risco trombótico num curto período, sendo, portanto, uma modalidade terapêutica inicial e de eleição para corrigir o EP em pacientes com SAF.

Short-term nutritional counseling reduces body mass index, waist circumference, triceps skinfold and triglycerides in women with metabolic syndrome

Background: It is recognized that the growing epidemic of metabolic syndrome is related to dietary and lifestyle changes. Objective: The purpose of this study was to evaluate short-term application of nutritional counseling in women with metabolic syndrome. Methods: This follow-up study was conducted from September to November 2008 with thirty three women >= 35 years old screened clinically for nutritional counseling. Dietary intake was reported, and biochemical and body composition measures were taken at baseline and after three months of follow-up. Results: Of the 33 women evaluated, 29 patients completed the study. The prevalence of type 2 diabetes mellitus, hypertension, dyslipidemia, and obesity was high at 38%, 72.4%, 55.2%, and 75.8%, respectively. At the end of three-months of follow-up, a significant decline in body mass index, waist circumference, triceps skinfold, and triglycerides was observed, as was an increase in calcium and vitamin D intake. The multiple regression analysis showed that changes in body mass index, triceps skinfold, waist circumference and triglyceride levels after nutritional intervention were positively associated with changes in anthropometric (loss of body weight) and biochemical (decrease of TG/HDL-c ratio) parameters. Moreover, waist circumference changes were negatively associated with changes in calcium and vitamin D intake. Conclusion: Short-term nutritional counseling improved some factors of metabolic syndrome. Moreover, the increases in calcium and vitamin D consumption can be associated with the improvement in markers of metabolic syndrome.

The International LAM Registry: A Component of an Innovative Web-Based Clinician, Researcher, and Patient-Driven Rare Disease Research Platform

Background: A relative friability to capture a sufficiently large patient population in any one geographic location has traditionally limited research into rare diseases. Methods and Results: Clinicians interested in the rare disease lymphangioleiomyomatosis (LAM) have worked with the LAM Treatment Alliance, the MIT Media Lab, and Clozure Associates to cooperate in the design of a state-of-the-art data coordination platform that can be used for clinical trials and other research focused on the global LAM patient population. This platform is a component of a set of web-based resources, including a patient self-report data portal, aimed at accelerating research in rare diseases in a rigorous fashion. Conclusions: Collaboration between clinicians, researchers, advocacy groups, and patients can create essential community resource infrastructure to accelerate rare disease research. The International LAM Registry is an example of such an effort.

Improvement in Quality of Life of An Oncological Patient by Laser Phototherapy

Objective and Background Data: Common side effects of radiotherapy (RT) to the head and neck include oral mucositis, xerostomia, and severe pain. The aim of this study is to report improvement in the quality of life of an oncological patient by laser phototherapy (LPT). Clinical Case and Laser Phototherapy Protocol: The patient, a 15-year-old girl diagnosed with mucoepidermoid carcinoma, underwent surgical excision of a tumor of the left palatomaxilla. After that, she was subjected to 35 sessions of RT (2 Gy/d). Clinical examination revealed the spread of severe ulcerations to the jugal mucosa, gums, lips, hard palate, and tongue (WHO mucositis score 3). She had difficulty in moving her tongue and she was unable to eat any solid food. Oral hygiene orientation and LPT were performed throughout all RT sessions. A continuous diode laser, 660 nm, 40 mW, 6 J/cm(2), 0.24 J per point in contact mode, with spot size of 0.04 cm(2) was used in the entire oral cavity. A high-power diode laser at 1 W, 10 sec per cm of mucositis, approximately 10 J/cm(2), was used in defocused mode only on ulcerative lesions. After the first laser irradiation session, decreases in pain and xerostomia were reported; however, a more significant improvement was seen after five sessions. At that point although the mucositis score was still 2, the patient reported that she was free of pain, and consequently a palatine plate could be made to rehabilitate the entire surgical area. Seventeen laser irradiation sessions were necessary to eliminate all oral mucositis lesions. Conclusion: Normal oral function and consequent improvements in the quality of life of this oncologic patient were observed with LPT.

A novel COL1A1 gene-splicing mutation (c. 1875+1G > C) in a Brazilian patient with osteogenesis imperfecta

Osteogenesis imperfecta is a heterogeneous genetic disorder characterized by bone fragility and deformity, recurrent fractures, blue sclera, short stature, and dentinogenesis imperfecta. Most cases are caused by mutations in COL1A1 and COL1A2 genes. We present a novel splicing mutation in the COL1A1 gene (c. 1875+ 1G>C) in a 16-year-old Brazilian boy diagnosed as a type III osteogenesis imperfecta patient. This splicing mutation and its association with clinical phenotypes will be submitted to the reference database of COL1A1 mutations, which has no other description of this mutation.

Hemoplasma Infection in HIV-positive Patient, Brazil

Hemotrophic mycoplasmas infect a variety of mammals. Although infection in humans is rarely reported, an association with an immunocompromised state has been suggested. We report a case of a Mycoplasma haemofelis-like infection in an HIV-positive patient co-infected with Bartonella henselae.

City tuberculosis control coordinators` perspectives of patient adherence to DOT in Sao Paulo State, Brazil, 2005

SETTING: Thirty-six priority cities in Sao Paulo State, Brazil, with a high incidence of tuberculosis (TB) cases, deaths and treatment default. OBJECTIVE: To identify the perspectives of city TB control coordinators regarding the most important components of adherence strategies adopted by health care teams to ensure patient adherence in 36 priority cities in the State of Sao Paulo, Brazil. DESIGN: Qualitative research with semi-structured interviews conducted with the coordinators of the National TB Control Programme involved in the management of TB treatment services in the public sector. RESULTS: The main issues thought to influence adherence to directly observed treatment (DOT) by coordinators include incentives and benefits delivered to patients, patient-health care worker bonding and comprehensive care, the encouragement given by others to follow treatment (family, neighbours and health professionals), and help provided by health professionals for patients to recover their self-esteem. CONCLUSION: The main aspects mentioned by city TB control coordinators regarding patient adherence to treatment and to DOT in Sao Paulo are improvements in communications, relationships based on trust, a humane approach and including the patients in the decision-making process concerning their health.

HIV testing and care of the patient co-infected with tuberculosis and HIV

Human immunodeficiency virus (HIV) infection poses one of the greatest challenges to tuberculosis (TB) control, with TB killing more people with HIV infection than any other condition. The standards in this chapter cover provider-initiated HIV counselling and testing and the care of HIV-infected patients with TB. All TB patients who have not previously been diagnosed with HIV infection should be encouraged to have an HIV test. Failing to do so is to deny people access to the care and treatment they might need, especially in the context of the wider availability of treatments that prevent infections associated with HIV A clearly defined plan of care for those found to be co-infected with TB and HIV should be in place., with procedures to ensure that the patient has access to this care before offering routine testing for HIV in persons with TB. It is acknowledged that people caring for TB patients should ensure that those who are HIV positive are transferred for the appropriate ongoing care once their TB treatment has been completed. In some cases, referral for specialised HIV-related treatment and care may be necessary during treatment for TB. The aim of these standards is to enable patients to remain as healthy as possible, whatever their HIV status.
