Value of Infrared Thermography Camera Attached to a Smartphone for Evaluation and Follow-up of Patients with Graves' Ophthalmopathy.

PURPOSE: Graves' ophthalmopathy (GO) is the most common extra-thyroid manifestation of Graves' disease (GD). The Clinical Activity Score (CAS) has been widely used to evaluate GO inflammation severity and response to treatment; however, it is quite subjective. Infrared thermography (IRT) is a portable and low-cost device to evaluate local temperature and assess inflammation. The aim was to evaluate ocular temperature by IRT as an instrument for measuring inflammatory activity in GO and its correlation with CAS. METHODS: This is a cross-sectional study involving 136 consecutive GD patients (12 with CAS ≥ 3/7, 62 with CAS < 3 and 62 without apparent GO) with 62 healthy controls. Patients with active ophthalmopathy were prospectively evaluated. Exophthalmometry, CAS, and thermal images from caruncles and upper eyelids were acquired from all subjects. RESULTS: All eye areas of thermal evaluation had higher temperatures in GD patients with active ophthalmopathy (caruncles, p<0.0001; upper eyelids, p<0.0001), and it was positively correlated with CAS (r=0.60 and p<0.0001 at caruncles; r=0.58 and p<0.0001 at upper eyelids). No difference in temperature was found between other groups. Patients with active ophthalmopathy were prospectively evaluated after 6 or 12 months of the treatment and a significant difference was found in ophthalmometry (p=0.0188), CAS (p=0.0205), temperature of caruncles (p=0.0120), and upper eyelids (p=0.0066). CONCLUSIONS: IRT was an objective and simple tool for evaluation and follow-up of inflammation in GO, allowed evidencing patients with significant inflammatory activity, and had a good correlation with the CAS score.

Short-acting insulin analogues versus regular human insulin on postprandial glucose and hypoglycemia in type 1 diabetes mellitus: a systematic review and meta-analysis.

INTRODUCTION: Strict glucose control using multiple doses of insulin is the standard treatment for type 1 diabetes mellitus (T1DM), but increased risk of hypoglycemia is a frequent drawback. Regular insulin in multiple doses is important for achieving strict glycemic control for T1DM, but short-acting insulin analogues may be better in reducing hypoglycemia and postprandial glucose levels. OBJECTIVE: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effects of short-acting insulin analogues vs regular human insulin on hypoglycemia and postprandial glucose in patients with T1DM. METHODS: Searches were run on the electronic databases MEDLINE, Cochrane-CENTRAL, EMBASE, ClinicalTrials.gov, LILACS, and DARE for RCTs published until August 2017. To be included in the study, the RCTs had to cover a minimum period of 4 weeks and had to assess the effects of short-acting insulin analogues vs regular human insulin on hypoglycemia and postprandial glucose levels in patients with T1DM. Two independent reviewers extracted the data and assessed the quality of the selected studies. The primary outcomes analyzed were hypoglycemia (total episodes, nocturnal hypoglycemia, and severe hypoglycemia) and postprandial glucose (at all times, after breakfast, after lunch, and after dinner). Glycated hemoglobin (HbA1c) levels and quality of life were considered secondary outcomes. The risk of bias of each RCT was assessed using the Cochrane Collaboration Risk of Bias table, while the quality of evidence for each outcome was assessed using the GRADEpro software. The pooled mean difference in the number of hypoglycemic episodes and postprandial glucose between short-acting insulin analogues vs. regular human insulin was calculated using the random-effects model. RESULTS: Of the 2897 articles retrieved, 22 (6235 patients) were included. Short-acting insulin analogues were associated with a decrease in total hypoglycemic episodes (risk rate 0.93, 95% CI 0.87-0.99; 6235 patients; I2 = 81%), nocturnal hypoglycemia (risk rate 0.55, 95% CI 0.40-0.76, 1995 patients, I2 = 84%), and severe hypoglycemia (risk rate 0.68, 95% CI 0.60-0.77; 5945 patients, I2 = 0%); and with lower postprandial glucose levels (mean difference/MD - 19.44 mg/dL; 95% CI - 21.49 to - 17.39; 5031 patients, I2 = 69%) and lower HbA1c (MD - 0,13%; IC 95% - 0.16 to - 0.10; 5204 patients; I2 = 73%) levels. CONCLUSIONS: Short-acting insulin analogues are superior to regular human insulin in T1DM patients for the following outcomes: total hypoglycemic episodes, nocturnal hypoglycemia, severe hypoglycemia, postprandial glucose, and HbA1c.

Insulin therapy in patients with cystic fibrosis in the pre-diabetes stage: a systematic review / Insulinoterapia em pacientes com fibrose cística na fase de pré-diabetes: uma revisão sistemática

Abstract Objective: To elucidate whether insulin is effective or not in patients with cystic fibrosis before the diabetes mellitus phase. Data source: The study was performed according to the Prisma method between August and September 2014, using the PubMed, Embase, Lilacs and SciELO databases. Prospective studies published in English, Portuguese and Spanish from 2002 to 2014, evaluating the effect of insulin on weight parameters, body mass index and pulmonary function in patients with cystic fibrosis, with a mean age of 17.37 years before the diabetes mellitus phase were included. Data synthesis: Eight articles were identified that included 180 patients undergoing insulin use. Sample size ranged from 4 to 54 patients, with a mean age ranging from 12.4 to 28 years. The type of follow-up, time of insulin use, the dose and implementation schedule were very heterogeneous between studies. Conclusions: There are theoretical reasons to believe that insulin has a beneficial effect in the studied population. The different methods and populations assessed in the studies do not allow us to state whether early insulin therapy should or should not be carried out in patients with cystic fibrosis prior to the diagnosis of diabetes. Therefore, studies with larger samples and insulin use standardization are required.

Resumo Objetivo: Elucidar se a insulina é eficaz ou não em pacientes com fibrose cística antes da fase de diabetes. Fontes de dados: O estudo foi feito de acordo com o método Prisma entre agosto e setembro de 2014, nas bases de dados PubMed, Embase, Lilacs e SciELO. Foram incluídos estudos prospectivos publicados em inglês, português e espanhol de 2002 a 2014 que avaliaram o efeito da insulina nos parâmetros peso, índice de massa corporal e função pulmonar, em pacientes com fibrose cística, com média de 17,37 anos, antes da fase de diabetes. Síntese dos dados: Foram identificados oito artigos que incluíram 180 indivíduos submetidos ao uso de insulina. O tamanho das amostras variou de 4 a 54 pacientes, idade média entre 12,4 e 28 anos. O tipo de acompanhamento, o tempo de uso de insulina, a dose e o cronograma de implementação foram muito heterogêneos entre os estudos. Conclusões: Existem razões teóricas para se acreditar que a insulina tenha um efeito benéfico na população estudada. Os diferentes métodos e populações encontrados não permitem afirmar se a terapia precoce com insulina deve ou não ser feita em pacientes com fibrose cística previamente ao diagnóstico de diabetes. Portanto, são necessários estudos com amostras maiores e uniformidade de uso da insulina.

A new compound heterozygosis for inactivating mutations in the glucokinase gene as cause of permanent neonatal diabetes mellitus (PNDM) in double-first cousins.

BACKGROUND: Permanent neonatal diabetes mellitus (PNDM) is a rare disorder, characterized by uncontrolled hyperglycemia diagnosed during the first 6 months of life. In general, PNDM has a genetic origin and most frequently it results from heterozygous mutations in KCNJ11, INS and ABCC8 genes. Homozygous or compound heterozygous inactivating mutations in GCK gene as cause of PNDM are rare. In contrast, heterozygosis for GCK inactivating mutations is frequent and results in the maturity-onset diabetes of young (MODY), manifested by a mild fasting hyperglycemia usually detected later in life. Therefore, as an autosomal recessive disorder, GCK-PNDM should be considered in families with history of glucose intolerance or MODY in first relatives, especially when consanguinity is suspected. RESULTS: Here we describe two patients born from non-consanguineous parents within a family. They presented low birth weight with persistent hyperglycemia during the first month of life. Molecular analyses for KCNJ11, INS, ABCC8 did not show any mutation. GCK gene sequencing, however, revealed that both patients were compound heterozygous for two missense combined in a novel GCK-PNDM genotype. The p.Asn254His and p.Arg447Gly mutations had been inherited from their mothers and fathers, respectively, as their mothers are sisters and their fathers are brothers. Parents had been later diagnosed as having GCK-MODY. CONCLUSIONS: Mutations' in silico analysis was carried out to elucidate the role of the amino acid changes on the enzyme structure. Both p.Asn254His and p.Arg447Gly mutations appeared to be quite damaging. This is the first report of GCK-PNDM in a Brazilian family.

[Prevalence and clinical aspects when it comes to the association between type 1 diabetes mellitus (DM1) and celiac disease]. / Prevalência e aspectos clínicos da associação de diabetes melito tipo 1 e doença celíaca.

OBJECTIVES: To estimate the prevalence of type 1 diabetes mellitus (DM1) and celiac disease association and to verify the existence of celiac disease symptoms, as well as the occurrence of other autoimmune diseases among the patients, their first-degree relatives and the possible influences of celiac disease in diabetes control. METHODS: It was done a cross-sectional study with 195 patients that answered a questionnaire about gastrointestinal symptoms and the occurrence of autoimmune diseases in their first-degree relatives. IgA was measured and antiendomysial antibody (EMA) was screened. The patients with positive EMA were submitted to intestinal biopsy. Those with celiac disease confirmed by biopsy (case group) were paired with DM1 patients without celiac disease (control group) according to age on diabetes diagnosis, diabetes duration and gender. RESULTS: EMA was positive in nine patients. In seven of them the biopsy has confirmed celiac disease (4.0%). Comparing the cases with controls, the gastrointestinal symptoms were significantly more frequent in the first group, but there was no difference between the groups regarding to the occurrence of autoimmune disease among the first-degree relatives and regarding to the control of diabetes (z weight, z height, insulin dose, HbA1c). CONCLUSIONS: The prevalence found was 4.0%. This sample of celiac patients showed a predominance of gastrointestinal symptoms, although the celiac disease did not influence the diabetes control.

Prevalência e aspectos clínicos da associação de diabetes melito tipo 1 e doença celíaca / Prevalence and clinical aspects when it comes to the association between type 1 diabetes mellitus (DM1) and celiac disease

OBJETIVOS: Verificar a prevalência da associação entre diabetes melito tipo 1 (DM1) e doença celíaca (DC) e a presença de sintomas da DC, a ocorrência de outras doenças auto-imunes entre os pacientes e seus parentes de primeiro grau e as possíveis influências da DC no controle do diabetes. MÉTODOS: Estudo transversal com 195 pacientes com DM1, que responderam ao questionário sobre a presença de sintomas gastrintestinais e a ocorrência de doenças auto-imunes em familiares. Foi dosada a IgA sérica e pesquisado o anticorpo antiendomísio (EMA). Os pacientes com EMA positivo foram submetidos à biópsia intestinal. Aqueles com DC confirmada por biópsia (grupo-casos) foram pareados com os pacientes apenas diabéticos (grupo-controle), de acordo com a idade ao diagnóstico de diabetes, o tempo de duração da doença e o gênero. RESULTADOS: O EMA foi positivo em nove pacientes. Em sete a biópsia confirmou DC (prevalência de 4 por cento). No pareamento de casos (DM1 e DC) e controles (somente DM1), os sintomas gastrintestinais foram significativamente mais freqüentes no grupo casos, não sendo observada diferença com a ocorrência de doenças auto-imunes entre os parentes de primeiro grau e com o controle do diabetes (z peso, z estatura, dose de insulina e HbA1c). CONCLUSÕES: A prevalência de DC neste grupo de pacientes com DM1 foi de 4 por cento. A amostra de pacientes celíacos apresentou predomínio de sintomas gastrintestinais, porém a presença de DC não interferiu no controle do diabetes.

[Insulin pump therapy in patients with type 1 diabetes]. / Uso de bomba de infusão subcutânea de insulina e suas indicações.

Both Continuous Subcutaneous Insulin Infusion (CSII) and Multiple Daily Injections (MDI) are effective ways of implementing intensive management of DM1 to attain near normal glycemic levels and a more flexible lifestyle. CSII is as safe as MDI and has some advantages over it mostly in diabetic patients with frequent hypoglycemias with important dawn phenomenum, gastroparesia, during pregnancy, in children and in patients with an erratic way of living. CSII allows a better chance to reach better glycemic control with less hypoglycemia, asymptomatic hypoglycemias and a better quality of life. Besides, risks are lower and adverse events are less frequent in DM1 patients under CSII as compared to MDI. To obtain results like this, a careful adjustment of basal and boluses insulin doses and an adequate patient follow-up are essential.

[Brazilian Consensus on second-generation antipsychotics and metabolic disorders]. / Consenso Brasileiro sobre antipsicóticos de segunda geração e distúrbios metabólicos.

OBJECTIVE: To discuss current aspects of use of antipsychotics considering their metabolic side effects profile, which includes weight gain, dyslipidemias, diabetes and metabolic syndrome. Such metabolic effects increase the risk of mortality by cardiovascular disease, which is the leading cause of death among schizophrenic patients. METHOD: A consensus meeting was held, with participation of endocrinologists and psychiatrists specialists in schizophrenia and, based on a literature review, an article was elaborated emphasizing practical and helpful recommendations to clinicians. RESULTS AND CONCLUSIONS: Monitoring metabolic side effects is essential to patients taking antipsychotics, particularly in the case of second generation antipsychotics. Efficacy and tolerability should be carefully balanced in all phases of treatment.

Uso de bomba de infusão subcutânea de insulina e suas indicações: [revisão] / Insulin pump therapy in patients with type 1 diabetes: [review]

Tanto a bomba de infusão de insulina quanto a terapêutica de múltiplas doses de insulina (MDI) são meios efetivos de implementar o manejo intensivo do diabetes melito tipo 1 (DM1), com o objetivo de chegar a níveis glicêmicos quase normais e obter-se um estilo de vida mais flexível. A terapia com bomba de infusão de insulina é tão segura quanto a MDI e tem vantagens sobre ela, sobretudo em pacientes com hipoglicemias freqüentes, com um fenômeno do alvorecer importante, com gastroparesia, na gravidez, em crianças e em pacientes com DM1 e com um estilo de vida errático. A terapia com bomba de infusão de insulina possibilita maior probabilidade de se alcançar melhor controle glicêmico com menos hipoglicemia, hipoglicemias assintomáticas e melhor qualidade de vida. Além disso, os riscos e os efeitos adversos da terapêutica insulínica em pacientes com DM1 em insulinização intensiva são menores nos pacientes usando esta terapia, quando comparados a pacientes em MDI. Para tal, o ajuste cuidadoso das doses basais e de bólus e o seguimento adequado do paciente são vitais.

OBJETIVO: Discutir os aspectos atuais do tratamento com os antipsicóticos, levando-se em consideração o perfil de efeitos metabólicos, tais como ganho de peso, diabetes, dislipidemias e síndrome metabólica. Tais fatores aumentam o risco de doença cardiovascular, que é a principal causa de morte nos portadores de esquizofrenia. MÉTODO: Foi realizada uma reunião de consenso com psiquiatras especialistas em esquizofrenia e endocrinologistas, os quais, com base nas evidências provenientes de ampla revisão da literatura, elaboraram um documento com recomendações que auxiliam a prática clínica. RESULTADOS E CONCLUSÕES: A avaliação periódica dos efeitos adversos metabólicos em pacientes que fazem uso de antipsicóticos é fundamental para a prática clínica, especialmente nos caso de antipsicóticos de segunda geração. O equilíbrio entre eficácia e tolerabilidade deve ser cuidadosamente considerado em todas as etapas do tratamento.

[Growth and body composition in children with type 1 diabetes mellitus]. / Crescimento e composição corporal de crianças com diabetes mellitus tipo 1.

OBJECTIVE: To evaluate the growth and body composition of pre-pubertal diabetic children, and to check for influence of the age of diabetes onset and length, sex, insulin requirement and glycosylated hemoglobin. PATIENTS AND METHODS: 59 diabetic children (39 M; 29 F), age 1.2-11.5 years, and 67 controls (36 M; 31 F), age 1.2-11.7 years were included. Weight, height, body mass index (BMI), arm circumference, skin folds, fat mass and muscle areas were evaluated and transformed into standard deviation scores (SDS). RESULTS: Among the diabetic children the mean height SDS was -0.13 (+/- 0.97) while in the control group it was 0.28 (+/- 0.86) (p= 0.013). The difference between the first and the current height SDS showed that the height SDS decreased significantly (p< 0.001) and multiple regression analysis indicated correlation with the duration of the disease. The mean arm fat SDS also revealed difference (p< 0.001). The means for weight, BMI, addition of 3 skinfolds and muscle mass did not demonstrate difference between the groups. CONCLUSIONS: The diabetic children showed reduction of height SDS during the period studied and they were significantly shorter than the controls, even though their statures were within the population standards. The arm fat area also showed an increase in relation with the controls.

Crescimento e composição corporal de crianças com diabetes mellitus tipo 1 / Growth and body composition in children with type 1 diabetes mellitus

OBJETIVOS: Avaliar o crescimento e a composição corporal de diabéticos tipo 1, pré-púberes, em relação à idade de início e tempo da doença, sexo, dose de insulina e hemoglobina glicada média. PACIENTES E MÉTODOS: Foram incluídas no estudo 59 crianças diabéticas (30 M; 29 F), entre 1,2 e 11,5 anos, e 67 controles (36 M; 31 F), entre 1,2 e 11,7 anos. Peso, altura, IMC, perímetro braquial, pregas cutâneas e áreas de massa gorda e muscular braquial foram avaliados e transformados em escore z. RESULTADOS: Verificou-se que entre os diabéticos a média de escore z de altura foi -0,13 (± 0,97), enquanto no grupo controle foi de 0,28 (± 0,86) (p= 0,013). A diferença entre os escores de altura inicial e atual mostrou perda estatural (p< 0,001) e a análise multivariada demonstrou associação com tempo de doença. Também observou-se diferença na área de gordura braquial (p< 0,001). As médias de escore z de peso, IMC, soma de 3 dobras e área muscular braquial não diferiram entre os grupos. CONCLUSÕES: As crianças diabéticas apresentaram perda de estatura durante o período de acompanhamento e eram significativamente mais baixas que os controles, embora suas alturas ainda estivessem dentro dos padrões de normalidade. Também mostraram área de gordura braquial aumentada em relação aos controles.

Crescimento puberal e altura final em 40 pacientes com diabetes mellitus tipo 1 / Pubertal growth and final height in 40 patients with type 1 diabetes mellitus

OBJETIVO: O diabetes mellitus tipo 1 (DM1) é a mais importante doença endócrino-metabólica crônica entre crianças e adolescentes, podendo ser causa de atraso do crescimento e da puberdade. Avaliamos a influência do DM1 no estirão de crescimento e na puberdade de indivíduos com doença iniciada antes ou no começo desta fase. CASUíSTICA E MÉTODOS: Foram avaliados retrospectivamente os prontuários de 40 pacientes (25 meninas), que apresentavam altura final, com coleta dos dados para o cálculo do tempo total de doença, os escores de DP da altura e do peso a cada consulta, a altura-alvo parental, as velocidades de crescimento (VC) anuais, o pico do estirão de crescimento, a duração da puberdade, o ganho total de crescimento durante o estirão puberal e a hemoglobina glicada (HbG). RESULTADOS: Em relação à adequação da altura final para a altura-alvo parental, 37 pacientes ficaram dentro da previsão e 3 ficaram abaixo do limite inferior. Não houve associação entre as variáveis analisadas com exceção da VC no pico do estirão, quando esta foi menor ou igual a 6cm/ano. A idade de início do DM1 e do pico do estirão puberal coincidiram com a faixa etária descrita na literatura; não foi observado atraso na idade de início da puberdade. No entanto, o ganho de altura durante a puberdade foi menor que o descrito na literatura, o mesmo ocorrendo em relação ao pico de VC puberal. De acordo com os valores da HbG, todos os pacientes avaliados apresentaram um controle crônico ruim do DM1. CONCLUSÕES: Neste grupo de DM1 com controle inadequado da doença, houve um prejuízo na altura final em relação à altura do início do DM1, provavelmente causado por uma baixa VC durante a puberdade, que, no entanto, não teve influência na altura final em relação ao alvo parental.

[Pubertal growth and final height in 40 patients with type 1 diabetes mellitus]. / Crescimento puberal e altura final em 40 pacientes com diabetes mellitus tipo 1.

OBJECTIVE: Type 1 diabetes mellitus (DM1), the most important chronic endocrine-metabolic disease in children and adolescents, may lead to delayed growth and puberty. In this study we analyzed the influence of DM1 on growth spurt and puberty of patients whose onset of the disease was before or at the beginning of this phase. PATIENTS AND METHODS: Data from 40 patients, 25 females, who had attained final height were retrospectively obtained, including duration of disease, patient's height and weight SDS at each consultation, parental target height, yearly growth velocities (GV), peak of growth spurt, duration of puberty, magnitude of growth spurt and glycated hemoglobin (HbA1C) levels. RESULTS: 37 patients had an adequate final height to parental target height, and only 3 were below the lower limit. There was no significant association among the variables and the appropriate final height to the target height, except for GV on growth spurt, when it was lower than or equal to 6 cm/year. The age of onset of DM1 and the age of peak of growth spurt was similar to previously data reported; regarding the age of the onset of puberty, there was no delay. However, the magnitude of the growth spurt and the peak of GV were lower. According to HbA1C levels, all patients exhibited a bad chronic control of DM1. CONCLUSIONS: In this group of inadequately controlled patients, the final height was lower than expected when compared to the height at onset of DM1, probably due to a slow GV during puberty, which however had no influence on the final height to parental target height.

A importância dos controles domiciliares na reduçäo de internaçäo em portadores de diabetes mellitus do tipo I / The importance of domiciliary control in internations reduction in patients with diabetes mellitus type I

Vários esquemas terapêuticos, geralmente com base na determinação da glicemia capilar, têm sido utilizados para melhorar o controle do diabetes mellitus do tipo 1 (DM1). Em vista da dificuldade de obtenção de múltiplas amostras sangüíneas diárias, pelo stress da punção e/ou pelo alto custo da determinação glicêmica, freqüentemente utilizamos a glicosúria como um parâmetro da glicemia. Em 1990 criamos um ambulatório específico para os diabéticos em nosso serviço e, desde 1992, com a doação de tiras para determinação domiciliar de glicemia, glicosúria e cetonúria aos pacientes carentes, passamos a cobrar o controle domiciliar. O objetivo do presente trabalho foi avaliar a influência da realização de controles domiciliares rotineiros no número de internações dos pacientes portadores de DM1. Analisamos os números: de pacientes acompanhados (P), de internações (I), de tiras distribuídas anualmente (U= glicosúria/cetonúria, S= glicemia) e a relação I/P. Observamos que apesar do aumento progressivo do número de pacientes acompanhados, houve queda das internações acompanhando o aumento progressivo do material fornecido para controle domiciliar, chegando a ser 6 a 8 vezes menor que as observadas em 1989. Houve correlação inversa entre o número de tiras urinárias fornecidas (U/P) e a porcentagem de internações (r= -0,83, p< 0,05). Concluímos que um grupo estruturado para tratamento de DM1 permitiu um melhor controle da doença com diminuição das internações e que apesar de pouco valorizada pela literatura, a determinação de glicosúria é importante no tratamento do DM1 na faixa etária pediátrica.
