Knowledge and habits of sun exposure in university students: a cross-sectional study in Southern Brazil.

BACKGROUND: Excessive sun exposure is the major risk factor for skin cancer. Thus, sun exposure behavior is the major focus for prevention of this disease, since it is potentially modifiable. Increasing the knowledge on sun related habits and other skin cancer risk factors is fundamental in the development of preventive programs, especially when directed to young people. OBJECTIVES: To assess the photoprotection habits and the knowledge about skin cancer in college students. METHODS: We conducted a cross-sectional study from Oct. 16 to Feb. 17, including 371 students from the Federal University of Santa Maria, RS, Brazil, through a self-administered questionnaire. RESULTS: The level of knowledge about skin cancer and photoprotection was unsatisfactory in more than 10% of the students. The occurrence of sunburn was extremely high among students, and 25% reported at least one episode of second degree sunburn. Proper use of sunscreen was referred by only 34% of individuals. Students who reported having received photo education in college were associated with a more consistent use of sunscreen. STUDY LIMITATIONS: health area represented a large part of the sample; instrument validated outside Brazil. CONCLUSIONS: Young people are unaware of basic information about sun protection and exposure. Even among those with proper knowledge, the use of photoprotective measures is very low. The sun exposure has shown to be excessive in most of the students, which makes this population an important target for photo-educational measures.

High-intensity interval training improves inflammatory and adipokine profiles in postmenopausal women with metabolic syndrome.

This study investigate the effects of high-intensity interval training (HIIT) on systemic levels of inflammatory and hormonal markers in postmenopausal women with metabolic syndrome (MS). Fifteen postmenopausal women with MS completed the training on treadmills. Functional, body composition parameters, maximal oxygen uptake (VO2max), and lipid profile were assessed before and after HIIT. Serum or plasma levels of cytokines and hormonal markers were measured along the intervention. The analysis of messenger RNA (mRNA) expression of these cytokines was performed in peripheral blood mononuclear cells (PBMC). VO2max and some anthropometric parameters were improved after HIIT, while decreased levels of proinflammatory markers and increased levels of interleukin-10 (IL-10) were also found. Adipokines were also modulated after 12 weeks or training. The mRNA expression of the studied genes was unchanged after HIIT. In conclusion, HIIT benefits inflammatory and hormonal axis on serum or plasma samples, without changes on PBMC of postmenopausal MS patients.

[Neurofibroma of thyroid in a patient with neurofibromatosis type 1]. / Neurofibroma de tireóide em uma paciente com neurofibromatose tipo 1.

The neurofibromatosis type 1 (NF1), also known as von Recklinghausens disease, is an autosomal dominant disorder, with high degree of variability of clinical expression, usually involved with formation of tumors, with benign origin in the majority of cases mainly localized in the region of the head and neck and rarely incident in the thyroid area. However, the association with medullary carcinoma of the thyroid (MCT) exists in literature and needs to be excluded. We report a case of a patient with NF1, nonfunctional thyroid nodule and obstructive symptoms. Surgical resection of lesion was performed, with histopathologic findings compatible with neurofibroma in thyroid tissue. This case is relevant not only because of the rarity of the presentation of NF1, but also due to the likely association with MCT, an aggressive tumor that can be cured by surgery.

Laparoscopic spleen-preserving distal pancreatectomy as treatment for nesidioblastosis after gastric bypass surgery.

Nesidioblastosis is characterized by hyperfunction of pancreatic islets caused by hypertrophic beta cells. Postprandial symptoms of hypoglycemia are the clinical presentation of the disease. A female patient with diabetes mellitus who underwent a Roux-en-Y gastric bypass began to present postprandial symptoms of hypoglycemia. There was no radiologic (MRI) evidence of insulinoma. Selective arterial calcium-stimulation test identified hyperfunction only in the splenic artery. Laparoscopic spleen-preserving distal pancreatectomy was performed. The patient has been entirely free of any postprandial symptoms for 10 months after the partial pancreatectomy.

Evaluation of the biochemical, inflammatory and oxidative profile of obese patients given clinical treatment and bariatric surgery.

BACKGROUND: We investigated the biochemical and inflammatory parameters as well as biomarkers of oxidative stress in morbidly obese patients before and after bariatric surgery and clinical treatment. METHODS: This study was conducted using 60 individuals (10 men and 50 women) distributed into 3 groups: the control group, 20 non-diabetic obese patients given clinical treatment, the bariatric group, 20 non-diabetic obese patients given a Roux-en-Y bypass gastroplasty, and the bariatric diabetic group, 20 diabetic obese patients given a Roux-en-Y bypass gastroplasty. Measurements were made before and 1, 3, 6, and 12months after surgery and clinical treatment. RESULTS: We showed a significant decrease in body weight, body mass index (BMI) and waist circumference, accompanied by a decrease in the lipid profile and glucose and glycated hemoglobin concentrations in the groups that received bariatric surgery. The concentrations of lipid peroxidation, carbonyl protein and NPSH, as well as superoxide dismutase (SOD) and catalase (CAT) activity, significantly decreased in both groups after surgery. The concentrations of inteleukin-6, inteleukin-1, TNF-α and resistin were also significantly lower, while adiponectin concentrations significantly increased 12months after bariatric surgery. No significant alterations were observed in the biochemical, inflammatory or oxidative parameters of the control group. CONCLUSIONS: Our findings demonstrate a decrease in body mass and a subsequent improvement in biochemical, metabolic and anthropometric parameters in patients given bariatric surgery. This may contribute to the reduction of oxidative damage in these patients and consequently a reduction in the risk of the development and progression of multiple co-morbidities associated with obesity.

Value of diagnostic tools for myocardial ischemia used in routine clinical practice to predict cardiac events in patients with type 2 diabetes mellitus: a prospective study.

OBJECTIVE: To analyze tests used in routine clinical practice for the diagnosis of myocardial ischemia to predict the development of cardiac events in type 2 diabetic patients. METHODS: The occurrence of cardiac events (new myocardial infarct, myocardial re-vascularization procedures, congestive heart failure, acute pulmonary edema, sudden death, and death after myocardial infarction or pulmonary edema) were prospectively assessed in a cohort of 135 type 2 diabetic patients after up to seven years of follow-up. At baseline, coronary artery disease was assessed by the WHO cardiovascular questionnaire, resting electrocardiogram, and stress myocardial scintigraphy. RESULTS: Forty-eight cardiac events were observed in 41 patients (10.5 events/100 patients-year). In a Cox's proportional-hazard model only the presence of symptoms of coronary artery disease on the WHO cardiovascular questionnaire alone (RR = 2.13, 95% CI 1.11-4.07, P= 0.022) or in combination with abnormalities on resting ECG (RR= 2.03, 95% CI 1.05-3.92, P= 0.034) or on myocardial scintigraphy (RR= 1.89, 95% CI 1.001-3.57, P= 0.050) predicted cardiac events, adjusted for fasting plasma glucose, mean blood pressure, body mass index, peripheral vascular disease and diabetic nephropathy. CONCLUSION: The WHO cardiovascular questionnaire, a simple tool for the diagnosis of coronary artery disease, is a significant predictor of cardiac events in type 2 diabetic patients.

Nail involvement in adult patients with plaque-type psoriasis: prevalence and clinical features.

BACKGROUND: Psoriasis is a disease of worldwide distribution with a prevalence of 1 to 3%. Nail psoriasis is estimated in 50% of patients with psoriasis, and in the presence of joint involvement, it can reach 80%. OBJECTIVE: To study the nail changes - and their clinical implications - presented by patients with psoriasis vulgaris under surveillance in a university hospital from the south of Brazil. METHODS: his cross-sectional study evaluated 65 adult patients from January 2012 to March 2013. Cutaneous severity was assessed according to the Psoriasis Area and Severity Index (PASI). The Nail Psoriasis Severity Index (NAPSI) was used to evaluate patient's nails. The diagnosis of psoriatic arthritis was established according to the Classification Criteria for Psoriatic Arthritis (CASPAR). RESULTS: The prevalence of NP was 46.1%. These patients had a median [interquartilic range (IQR)] NAPSI of 1 (0-15). A total of 63.3% of patients reported aesthetic discomfort or functional impairment related to their nails. Onycholysis was the most common feature (80%). When compared with patients without nail involvement, patients with NP had lower mean age at psoriasis onset [21 (18-41) vs. 43 (30-56) years, p=0,001]; longer disease duration [15.5 (10-24) vs. 6 (2-12) years, p=0.001]; higher PASI [9.2 (5-17) vs. 3.7 (2-10), p=0.044], higher frequency of psoriatic arthritis (43.3 vs. 3.7, p = 0.002) and more often reported family history of psoriasis (40% vs. 7.4%, p = 0.011). CONCLUSION: Onycholysis was the most frequent finding and most patients feel uncomfortable with the psoriatic nail changes that they experience.

Association among microalbuminuria and oxidative stress biomarkers in patients with type 2 diabetes.

AIM: Hyperglycemia in diabetes mellitus (DM) may be one of the most important factors responsible for the development of oxidative stress, which promotes the main complications in DM patients. Therefore, this study evaluated if the hyperglycemia could be related to oxidative stress biomarkers, lipid profile, and renal function in type 2 diabetes patients without clinic complications. METHODS: Plasmatic malondialdehyde (MDA), serum protein carbonyl (PCO), serum creatinine levels, microalbuminuria, glycated hemoglobin, and lipid profile were analyzed in 37 type 2 diabetic patients and 25 subjects with no diabetes. RESULTS: Serum creatinine levels were within the reference values, but microalbuminuria presented increased levels in all the patients compared with controls (P < 0.05) and above of the reference values. The MDA, PCO, low-density lipoprotein, and triglyceride levels showed positive correlation with microalbuminuria levels. Moreover, glycated hemoglobin presented positive correlation with MDA, PCO, and microalbuminuria levels. CONCLUSIONS: The hyperglycemia could be responsible for the increase of the microalbuminuria levels and for the oxidation process in lipids and proteins in DM patients. Therefore, we suggested that the microvascular lesion is a direct consequence from hyperglycemia and an indirect one from the increased oxidative stress. Malondialdehyde and protein carbonyl levels could be suggested as additional biochemical evaluation to verify tissue damage in type 2 DM patients.

Sarcopenia: evaluation of different diagnostic criteria and its association with muscle strength and functional capacity / Sarcopenia: avaliação de diferentes critérios diagnósticos e sua associação com a força muscular e capacidade funcional

INTRODUCTION: Sarcopenia has been associated with increased morbidity and mortality in older people. However, there is still no consensus about the best diagnostic criteria for it. OBJECTIVE: This study aimed to evaluate different diagnostic criteria of sarcopenia and their relationship with muscle strength and functional capacity. METHODS: A cross-sectional study was carried out in Santa Maria-RS, Brazil. Body composition was measured by dual-energy X-ray absorptiometry (DXA). Physical performance was evaluated by the Timed-get-up-and-go test (TGUG). Muscle strength was measured with a handgrip dynamometer. The proposed criteria of sarcopenia were evaluated as follows: A) appendicular lean mass index (aLM/ht2), cutoffs 5.5 kg/m2, 2SD, 10th percentile, and 20th percentile of young reference; B) a linear regression model was used to adjust appendicular lean mass (aLM) for both height and fat mass, cutoff 20th percentile of elderly. RESULTS: In total, 104 women agreed to participate in the research, 39 young (20 to 40 years) and 65 elderly (over 60 years). The prevalence of sarcopenia varied from 0% to 17.2% according to the diagnostic criteria. Regarding muscle strength, the aLM/ht2 cutoff 10th percentile was the criterion with greater area under the ROC curve. However, there were no criteria with an area under the ROC curve greater than 0.5 when TGUG was the outcome. The reclassification showed that the criterion B reclassified 66.7% with normal grip strength as sarcopenic. CONCLUSION: Of these criteria, aLM/ht2 cutoff 10th percentile had stronger correlation with muscle strength.

INTRODUÇÃO: Sarcopenia está associada com aumento da morbidade e mortalidade em pessoas idosas. No entanto, ainda não existe consenso sobre o melhor critério diagnóstico para ela. OBJETIVO: Avaliar os diferentes critérios diagnósticos de sarcopenia e sua relação com a força muscular e capacidade funcional. MÉTODOS: Estudo transversal realizado em Santa Maria-RS, Brasil. A composição corporal foi avaliada através de absorciometria por dupla emissão de raios-x (DXA). A capacidade funcional foi inferida por meio dos testes Timed-get-up-and-go (TGUG) e preensão manual com um dinamômetro. Os critérios de sarcopenia propostos foram: A) índice de massa muscular apendicular (aLM/ht²), pontos de corte de 5,5 kg/m2, dois desvios-padrões (dp), percentil 10 e percentil 20 da amostra jovem de referência; B) modelo de regressão linear utilizando massa muscular apendicular (aLM) ajustado para altura e massa gorda (percentil 20 da amostra de idosos). RESULTADOS: No total, 104 mulheres concordaram em participar da pesquisa, 39 jovens (20 a 40 anos) e 65 idosas (acima de 60 anos). A prevalência de sarcopenia variou de 0% a 17,2%, conforme o critério utilizado. Em relação à força muscular, o percentil 10th do aLM/ht² foi o critério com maior área sob a curva ROC. No entanto, nenhum dos critérios diagnósticos para sarcopenia apresentou área sob a curva ROC maior que 0,5 quando TGUG foi utilizado. CONCLUSÃO: Dos critérios avaliados, aLM/ht2 percentil 10 apresentou melhor correlação com força muscular.

Transverse myelitis associated to HCV infection.

Complications involving the central nervous system in patients suffering from hepatitis C virus (HCV) infection have been rare. Among them, it appears the transverse myelitis, which has already been reported in likely association with HCV. This paper presents the case study of a 65-year-old woman who developed cervical transverse myelitis linked to chronic HCV infection and anti-HCV antibodies in the spinal fluid, being excluded other etiologies for transverse myelitis. Current evidence has reinforced the likely association between chronic HCV infection and transverse myelitis, especially as recurrent manifestations of the disease. These findings reveal the need for more searching to establish the causal relationship between transverse myelitis and hepatitis C.

Neurofibroma de tireóide em uma paciente com neurofibromatose tipo 1 / Neurofibroma of thyroid in a patient with neurofibromatosis type 1

A neurofibromatose tipo 1 (NF1), também conhecida como doença de von Recklinghausen, é uma doença autossômica dominante com alto grau de variabilidade da expressão clínica, comumente envolvida na formação de tumorações na maioria das vezes de origem benigna, localizadas principalmente na região da cabeça e do pescoço, sendo a tireóide acometida raramente. Porém existe na literatura a associação com carcinoma medular da tireóide (CMT), necessitando sempre sua exclusão. Relatamos o caso de uma paciente com NF1, com um nódulo de tireóide não-funcionante e sintomas obstrutivos. Foi realizada ressecção cirúrgica da lesão, com achados histopatológicos compatíveis com neurofibroma em tecido tireoidiano. A importância desse caso deve-se não só à raridade dessa apresentação da NF1, mas também à possibilidade de associação desta com CMT, tumor agressivo com possibilidade de cura pela ressecção cirúrgica.

Value of diagnostic tools for myocardial ischemia used in routine clinical practice to predict cardiac events in patients with type 2 diabetes mellitus: a prospective study

OBJETIVO: Analisar os testes usados na prática clínica de rotina para diagnóstico de isquemia miocárdica na predição do desenvolvimento de eventos cardíacos em pacientes com diabetes mellitus tipo 2 (DM2). MÉTODOS: A ocorrência de eventos cardíacos (novo infarto do miocárdio [IM], procedimentos de re-vascularização miocárdica, insuficiência cardíaca congestiva, edema agudo de pulmão, morte súbita e morte após IM ou edema pulmonar) foi avaliada prospectivamente em uma coorte de 135 pacientes com DM2 após até 7 anos de acompanhamento. Na condição basal, a doença arterial coronariana (DAC) foi avaliada pelo questionário cardiovascular da OMS, eletrocardiograma de repouso e cintilografia do miocárdio sob stress. RESULTADOS: 48 eventos cardíacos foram observados em 41 pacientes (10,5 eventos/100 pacientes-ano). No modelo de risco proporcional de Cox apenas a presença de sintomas de DAC no questionário cardiovascular da OMS isoladamente (RR= 2,13, 95% CI 1,11­4,07, P= 0,022) ou em combinação com anormalidades no ECG de repouso (RR= 2,03, 95% CI 1,05­3,92, P= 0,034) ou cintilografia do miocárdio (RR= 1,89, 95% CI 1,001­3,57, P= 0,050) predisseram eventos cardíacos, ajustados para a glicemia de jejum, pressão arterial média, índice de massa corporal, doença vascular periférica e nefropatia diabética. CONCLUSÃO: O questionário cardiovascular da OMS, um procedimento simples para o diagnóstico da DAC, é um preditor significativo de eventos cardíacos em pacientes com DM2.

Neuropatia autônoma cardiovascular em pacientes com diabetes “mellitus” tipo 2 / Cardiovascular autonomic neuropathy in diabetic mellitus type 2 patients

A neuropatia autônoma acomete grande parte dos pacientes diabéticos. Este acometimento pode envolver diversos órgãos e sistemas e isso geralmente ocorre de forma desigual. O envolvimento do sistema nervoso autônomo no decurso do diabetes mellitus (DM) é bem estabelecido e está associado com aumento da mortalidade. A presença de neuropatia autônoma cardíaca (NAC), evidenciada por alterações nas variações de freqüência cardíaca, está associada a uma mortalidade de 29 por cento em 10 anos, enquanto que naqueles pacientes ilesos de NAC essa taxa representa apenas 6 por cento. Devido ao valor prognóstico na NAC, é importante avaliarmos a sua presença nos pacientes com DM, bem como orient´-alos quanto às suas associações. Descrevemos os dados encontrados em nosso ambulatório e discutimos as evidências na NAC encontradas na literatura

Ainda é útil o uso de bicabornato no tratamento da cetoacidose diabética? / is still useful the use of bicabornate in the treatment of diabetic ketoacidosis?

O uso de bicarbonato de sódio no tratamento da cetoacidose diabética ainda é discutível e há poucos dados na literatura sobre este assunto. O objetivo do presente trabalho foi analisar retrospectivamente os aspectos evolutivos de pacientes com cetoacidose grave (pH arterial < 7,1) tratados ou nao com bicarbonato. Foram identificados 11 pacientes que receberam bicarbonato de sódio (60 a 350 mEq) durante o tratamento da cetoacidose diabética e outros 11 pacientes que nao receberam tratamento alcalinizante. Os pacientes de cada grupo eram semelhantes em relaçao a idade, proporçao de sexos, tipo e duraçao de diabete, níveis glicêmicos e de acidose metabólica na admissao. Os pacientes que receberam bicarbonato nao diferiram dos que nao receberam este tratamento quanto ao tempo de recuperaçao da glicemia (7,8 ñ 6,5 vs 6,1 ñ 3,7 horas), tempo de desaparecimento da cetose (40,7ñ 19,1 vs 34,6 ñ 15,5 horas), a dose total de insulina empregada (223 ñ 132 vs 202 ñ 134 unidades), quantidade total de líquidos infundidos (l2,7 ñ 5,6 vs 12,3 ñ 4,6 litros), assim como, o número de episódios de hipopotassemia (2/8 vs 2/8) e de hipoglicemia (2/9 vs 1/9). Ocorreram 2 casos de óbito, ambos no grupo de pacientes que recebeu bicarbonato. O uso de bicarbonato nao esteve associado a qualquer benefício terapêutico e, portanto, nao há justificativa para o seu emprego rotineiro no tratamento da cetoacidose diabética.
