Association between ear creases and peripheral arterial disease

INTRODUCTION: Peripheral arterial disease is a severe manifestation of atherosclerosis that can lead to critical ischemia of the lower limbs and is also associated with high cardiovascular risk. Diagonal lobular and anterior tragal ear creases have been associated with coronary artery disease, but they have not yet been investigated in patients with peripheral arterial disease.OBJECTIVES: To evaluate the prevalence of ear creases among patients with peripheral arterial disease of the lower limbs, compared with patients without documented atherosclerotic disease.METHODS: Cross-sectional study including 60 male patients with peripheral arterial disease of the lower limbs and 60 dermatologic outpatients matched for age and gender. The associations were adjusted for other risk factors by conditional logistic regression.RESULTS: The prevalence of diagonal and anterior tragal ear creases was higher among cases (73% vs. 25% and 80% vs. 43%, respectively) than controls; these associations remained significant even when adjusting for other known risk factors of atherosclerosis (odds ratio = 8.1 and 4.1, respectively).CONCLUSIONS: Ear creases are independently associated with peripheral arterial disease and may be an external marker for risk identification.

Armadillo meat intake was not associated with leprosy in a case control study, Curitiba (Brazil)

Leprosy's progression and its maintained endemic status, despite the availability of effective treatments, are not fully understood and recent studies have highlighted the possibility of involved Mycobacterium leprae ambient reservoirs. Wild armadillos can carry leprosy and, because their meat is eaten by humans, development of the disease among armadillo meat consumers has been investigated. This study evaluated the frequency of armadillo meat intake among leprosy patients as well as age and gender matched controls with other skin diseases from a dermatological unit. Armadillo meat consumption among both groups was adjusted by demographic and socioeconomic covariates based on a conditional multiple logistic regression model. One hundred twenty-one cases and 242 controls were evaluated; they differed in socioeconomic variables such as family income, hometown population and access to treated water. The multivariate analysis did not show an association between the intake of armadillo meat and leprosy (odds ratio = 1.07; CI 95% 0.56-2.04), even when only cases with no known contacts were analyzed. We conclude that leprosy is not associated with the intake of armadillo meat in these patients.

Associação entre doença arterial coronariana e as pregas lobular diagonal e anterotragal em homens

FUNDAMENTOS: Diversas alterações dermatológicas foram associadas à doença arterial coronariana, representando achados de fácil constatação que podem contribuir na estratificação não invasiva do risco cardíaco. OBJETIVOS: Avaliar comparativamente a prevalência de certos achados dermatológicos em pacientes com ou sem doença arterial coronariana. MÉTODOS: Estudo caso/controle envolvendo pacientes do sexo masculino submetidos à cineangiocoronariografia. Foram considerados aqueles casos com obstrução de mais de 50% em pelo menos uma coronária. Avaliou-se a presença da prega lobular diagonal, prega anterotragal, alopecia e presença de pêlos no tórax nos dois grupos. Os resultados foram ajustados para os fatores de risco: tabagismo, hipertensão, diabetes, idade, dislipidemia e índice de massa corporal. RESULTADOS: Analisaram-se 110 pacientes (80 casos e 30 controles). A prevalência da prega lobular diagonal nos casos (60,0%) foi maior do que no grupo controle (30,0%) (p<0,05). Alopecia androgenética e distribuição de pêlos no tórax não demonstraram associação positiva com coronariopatia neste estudo. O Odds Ratio (IC 95%), da prega lobular diagonal foi de 3,1 (1,2-8,3) e para prega anterotragal foi de 5,5 (1,9-16,3). A verificação simultânea da prega lobular diagonal e prega anterotragal representou valor preditivo positivo de 90%. CONCLUSÕES: Detectou-se associação positiva entre a presença da prega lobular diagonal bilateral e prega anterotragal bilateral com doença arterial coronariana, sendo que a presença simultânea das duas pregas apresenta alta preditividade para doença arterial coronariana.

Effect of soluble fiber on hypertriglyceridemia and immune profile in HIV-positive individuals undergoing highly active antiretroviral therapy

The advent of highly active antiretroviral therapy (HAART), since 1996, represented a profound impact on the natural history of HIV-infection by promoting important and sustainable viral replication suppression and increasing survival and quality of life among seropositive patients. Nonetheless, antiretroviral therapy has been observed to be accompanied by metabolic alterations such as dyslipidemia, especially hypertriglyceridemia, insulin resistance, hyperglycemia and lipodystrophy (body fat redistribution). Epidemiological studies have demonstrated a correlation between high triglyceride (TG) levels and higher incidence of coronary artery disease (CAD). Some investigators suggest dietary intervention as part of hyperlipidemia treatment, including an increase in soluble fiber intake (10-25g/day). Whereas some studies have demonstrated that both cholesterol and serum triglyceride levels decrease with the use of food fiber, others have shown just a serum triglyceride decrease, and others failed to observe any alteration in lipid metabolism. The purpose of this study was to assess the effect of soluble fiber (R) (partially hydrolyzed guar gum) supplementation on hypertriglyceridemia and immune profile in HIVpositive individuals on HAART. Nineteen HIV-positive individuals with hypertriglyceridemia (serum levels >= 150 to < 500mg/dl) were studied. of these individuals, 63.16% were males and 36.84% females, with mean age of 43.52 +/- 9.22 years. These individuals had been on the same HAART regimen for at least six months, had no change in therapy during the study and received 20g/day of soluble fiber for four months at pre-established times. Clinical-nutritional, biochemical (total proteins, albumin, globulin, total cholesterol, LDL-c, HDL-c, TG, TG/HDL-c and LDLc/HDL-c), hematimetric (hemoglobin, hematocrit and total lymphocytes), and immunologic (lymphocytes T CD4(+), T CD8(+); T CD4(+)/CD8(+) ratio, viral load, TNF-alpha and IL-6) parameters were assessed in all patients at three time points (M0: pretreatment, M1: 30 days, and M2: four months after intervention). Significance level was set at 5% for all data statistically analyzed. Serum TG and TG/HDL-c ratio reduction was observed at all time points, but statistical significance was found just at M0 and M2. The remaining biochemical, hematimetric and immunologic parameters (lymphocytes T CD4(+), T CD8(+); T CD4(+)/ CD8(+) ratio, and viral load) showed no significant difference at all times. Regarding serum cytokines, TNF-alpha and IL-6 significantly decreased between M0 and M2, and only IL-6 reduced between M1 and M2. The data collected show that dietary and anthropometric parameters remained unchanged excluding potential confounding factors related with the effect of fiber supplementation on serum TG, TNF-alpha and IL-6. Thus, soluble fiber (R) contributed to an important reduction in hypertriglyceridemia and in the serum levels of the proinflammatory cytokines TNF-alpha and IL-6 in HIV-seropositive individuals on HAART. In addition, soluble fiber (R) might have minimized the process of atherosclerosis in these individuals, given that elevated serum levels of TG, TNF-alpha and IL-6 have been associated with the development of these lesions.

Experiências de famílias na imunização de crianças brasileiras menores de dois anos

O objetivo foi descrever as experiências de famílias sobre imunização de crianças menores de dois anos. É estudo de natureza descritiva, com análise qualitativa dos dados, entrevistas não estruturadas com 22 sujeitos. Os resultados foram agrupados em: conhecimentos práticos sobre imunização, responsabilidade e obrigatoriedade na imunização e ampliação da prática de imunização. Foram destacados elementos que fortalecem a imunização: experiência e realização pessoal no papel de ser mãe, temor de adoecimento, reconhecimento como um bom cuidado, acesso, flexibilidade do horário, divulgação, cartão de vacinas, campanhas de vacinação e disponibilidade de vacinas, e elementos da não imunização: inexperiência dos pais, recusa de aplicações simultâneas de vacinas, assistência fragmentada, ausência de diálogo, discriminação, falsas contraindicações e obrigatoriedade. A imunização centrada no cumprimento do calendário vacinal, ou em situações autoritárias, está descolada do cuidado familiar. O vínculo com as famílias precisa ser fortalecido para ampliação da adesão às medidas de proteção e promoção da saúde da criança.

Motile sperm organelle morphology examination (MSOME): intervariation study of normal sperm and sperm with large nuclear vacuoles

Background: Although the motile sperm organelle morphology examination (MSOME) was developed only as a selection criterion, its application as a method for classifying sperm morphology may represent an improvement in evaluation of semen quality, with potential clinical repercussions. The present study aimed to evaluate individual variations in the motile sperm organelle morphology examination (MSOME) analysis after a time interval.Methods: Two semen samples were obtained from 240 men from an unselected group of couples undergoing infertility investigation and treatment. Mean time interval between the two semen evaluations was 119 +/- 102 days. No clinical or surgical treatment was realized between the two observations. Spermatozoa were analyzed at greater than or equal to 8400 x magnification by inverted microscope equipped with DIC/Nomarski differential interference contrast optics. At least 200 motile spermatozoa per semen sample were evaluated and percentages of normal spermatozoa and spermatozoa with large nuclear vacuoles (LNV/one or more vacuoles occupying >50% of the sperm nuclear area) were determined. A spermatozoon was classified as morphologically normal when it exhibited a normal nucleus (smooth, symmetric and oval nucleus, width 3.28 +/- 0.20 mu m, length 4.75 +/- 0.20 mu m/absence of vacuoles occupying >4% of nuclear area) as well as acrosome, post-acrosomal lamina, neck and tail, besides not presenting cytoplasm around the head. One examiner, blinded to subject identity, performed the entire study.Results: Mean percentages of morphologically normal and LNV spermatozoa were identical in the two MSOME analyses (1.6 +/- 2.2% vs. 1.6 +/- 2.1% P = 0.83 and 25.2 +/- 19.2% vs. 26.1 +/- 19.0% P = 0.31, respectively). Regression analysis between the two samples revealed significant positive correlation for morphologically normal and for LNV spermatozoa (r = 0.57 95% CI: 0.47-0.65 P < 0.0001 and r = 0.50 95% CI: 0.38-0.58 P < 0.0001, respectively).Conclusions: The significant positive correlation and absence of differences between two sperm samples evaluated after a time interval with respect to normal morphology and LNV spermatozoa indicated that MSOME seems reliable (at least for these two specific sperm forms) for analyzing semen. The present result supports the future use of MSOME as a routine method for semen analysis.

A new ovarian response prediction index (ORPI): implications for individualised controlled ovarian stimulation

Background: The objective was to present a new ovarian response prediction index (ORPI), which was based on anti-Mullerian hormone (AMH) levels, antral follicle count (AFC) and age, and to verify whether it could be a reliable predictor of the ovarian stimulation response.Methods: A total of 101 patients enrolled in the ICSI programme were included. The ORPI values were calculated by multiplying the AMH level (ng/ml) by the number of antral follicles (2-9 mm), and the result was divided by the age (years) of the patient (ORPI=(AMH x AFC)/Patient age).Results: The regression analysis demonstrated significant (P<0.0001) positive correlations between the ORPI and the total number of oocytes and of MII oocytes collected. The logistic regression revealed that the ORPI values were significantly associated with the likelihood of pregnancy (odds ratio (OR): 1.86; P=0.006) and collecting greater than or equal to 4 oocytes (OR: 49.25; P<0.0001), greater than or equal to 4 MII oocytes (OR: 6.26; P<0.0001) and greater than or equal to 15 oocytes (OR: 6.10; P<0.0001). Regarding the probability of collecting greater than or equal to 4 oocytes according to the ORPI value, the ROC curve showed an area under the curve (AUC) of 0.91 and an efficacy of 88% at a cut-off of 0.2. In relation to the probability of collecting greater than or equal to 4 MII oocytes according to the ORPI value, the ROC curve had an AUC of 0.84 and an efficacy of 81% at a cut-off of 0.3. The ROC curve for the probability of collecting greater than or equal to 15 oocytes resulted in an AUC of 0.89 and an efficacy of 82% at a cut-off of 0.9. Finally, regarding the probability of pregnancy occurrence according to the ORPI value, the ROC curve showed an AUC of 0.74 and an efficacy of 62% at a cut-off of 0.3.Conclusions: The ORPI exhibited an excellent ability to predict a low ovarian response and a good ability to predict a collection of greater than or equal to 4 MII oocytes, an excessive ovarian response and the occurrence of pregnancy in infertile women. The ORPI might be used to improve the cost-benefit ratio of ovarian stimulation regimens by guiding the selection of medications and by modulating the doses and regimens according to the actual needs of the patients.

Body dysmorphic disorder among dermatologic patients: Prevalence and clinical features

Background: An impairing preoccupation with a nonexistent or slight defect in appearance is the core symptom of body dysmorphic disorder (ODD), a psychiatric condition common in dermatology settings.Objective: We sought to determine the prevalence of ODD in dermatologic patients, comparing general and cosmetic settings, and describing some demographic and clinical characteristics.Methods: In all, 300 patients were consecutively assessed. Screening and diagnoses were performed with validated instruments plus a best estimate diagnosis procedure. The final sample comprised 150 patients in the cosmetic group, 150 patients in the general dermatology group, and 50 control subjects. Standard statistical analyses were performed (chi(2), nonparametric tests, logistic regression).Results: The current prevalence was higher in the cosmetic group (14.0%) compared with general (6.7%) and control (2.0%) groups. No patient had a previous diagnosis. Frequently the reason for seeking dermatologic treatment was not the main ODD preoccupation. Patients with ODD from the cosmetic group were in general unsatisfied with the results of dermatologic treatments.Limitations: Cross-sectional study conducted in a university hospital is a limitation. It is uncertain if the findings can be generalized. Retrospective data regarding previous treatments are not free from bias.Conclusions: BUD is relatively common in a dermatologic setting, especially among patients seeking cosmetic treatments. These patients have some different features compared with general dermatology patients. Dermatologists should be aware of the clinical characteristics of ODD to identify and refer these patients to mental health professionals. (J Am Acad Dermatol 2010;63:235-43.)

Sentimentos e percepções de puérperas com relação à assistência prestada pelo serviço materno-infantil de um hospital universitário

OBJETIVOS: avaliar percepções e sentimentos de puérperas adultas e adolescentes, relacionados ao filho e a assistência materno-infantil, em hospital universitário de nível terciário. MÉTODOS: estudo transversal, envolvendo 180 puérperas, no Alojamento Conjunto (AC) e no Berçário Interno (BI) do Hospital das Clínicas da Faculdade de Medicina de Botucatu , entrevistadas no segundo e terceiro dia pós-parto e distribuídas em três grupos: adultas primíparas, adultas multíparas e adolescentes. Para comparação entre grupos e locais de internação utilizou-se o chi2 ou teste de Fisher. RESULTADOS: ultrasom obstétrico e cardiotocografia tiveram impacto positivo na emoção materna. Houve pouca diferença entre os grupos quanto aos sentimentos antes e após o parto, sendo felicidade, amor, responsabilidade, ansiedade e medo os mais freqüentes. A culpa predominou nas adolescentes do BI. As percepções relacionadas ao filho, a avaliação da assistência e equipe, não diferiram entre adultas e adolescentes. Nas duas enfermarias o relacionamento entre mães e cuidadores foi bom, as mães mostraram-se satisfeitas com a equipe e a assistência, mas o aleitamento materno foi pouco valorizado e poucas mães conheciam o médico. CONCLUSÕES: está ocorrendo um processo de humanização na assistência materno-infantil deste hospital universitário, mas alguns aspectos precisam ser melhorados, especialmente a valorização do aleitamento materno e a individualização no contato médico-paciente.
