A presença de depressão no paciente com diabetes mellitus (DM) parece relacionar-se a alterações no curso clínico da doença. O objetivo deste trabalho é realizar uma revisão sistemática sobre a associação entre o DM e depressão. Foi realizada uma pesquisa bibliográfica utilizando as bases de dados MEDLINE e LILACS para identificar artigos relevantes, publicados entre 1990 e 2001, que avaliassem esta associação. Foram analisadas informações referentes à prevalência, ao impacto e ao tratamento da depressão no DM. A prevalência de depressão no DM variou de 0 a 60,5%. Sintomas depressivos relacionaram-se a um pior controle glicêmico, a um aumento e a uma maior gravidade das complicações clínicas, a uma piora da qualidade de vida e ao comprometimento de aspectos sociais, econômicos e educacionais ligados ao DM. O tratamento da depressão está relacionado à melhora dos níveis glicêmicos, podendo contribuir para um melhor controle de diversos aspectos relacionados ao DM. The presence of depression in a patient with diabetes mellitus (DM) seems to be related to changes in the clinical course of the disease. The purpose of this study is to perform a systematic review on the association of DM and depression. A bibliographic search was performed using the MEDLINE and LILACS databases to identify relevant articles, published from 1990 to 2001, which evaluate this relationship. Information concerning prevalence, impact and treatment of depression in DM were analyzed. The prevalence of depression varied from 0 to 60.5%. The presence of depressive symptoms were associated with a poor glycemic control, an increase in the number and severity of clinical complications, a worse quality of life and impairment of social, educational and economic aspects related to DM. The treatment of depression is associated with an improvement in glycemic levels, which may contribute to a better control of several aspects related to DM.

The aim of this study was to translate into Portuguese and to assess the reliability of an instrument for the diagnosis of diabetic distal polyneuropathy (DPN). The process for translation and adaptation into Portuguese of the Neuropathy Symptom Score (NSS) and the Neuropathy Disability Score (NDS) was performed following internationally standardized procedures. The instruments were applied by 2 raters in 57 consecutive subjects. Spearman correlation was used to evaluate the reliability and Cronbachs' alpha to evaluate the internal consistency of the items. Both, ECN and ESN, showed a good reliability (r= 0.77, p< 0.0001 and r= 0.76, p< 0.0001, respectively). ESN showed a good internal consistency (alpha= 0.74). The diagnosis of DPN, defined as the combination of the two scores (ECN+ESN) also showed a good reliability (r= 0.63, p< 0.0001). The Portuguese versions of the ESN and the ECN seem to be adequate for the diagnosis of DPN in this population.

In our study sample, the occurrence of eating disorders was increased compared to rates observed in the general population, with the predominance of binge eating disorder. The presence of an eating disorder in type 2 diabetes mellitus patients was associated with higher rates of anxiety disorders.

It has already been demonstrated that insulin resistance (IR) is associated with the stimulation of erythroid progenitors and with increased levels of inflammation markers. Therefore, IR should also be associated with increased red blood cell (RBC) and white blood cell (WBC) count. The aim of this study is to demonstrate that IR is independently associated with altered hematological parameters in a Brazilian sample. We analyzed laboratorial exams from 925 subjects. All data on hematological parameters, insulin resistance (Homeostasis Model Assessment [HOMA]) and lipid levels were included in the analysis. Demographic information included age and gender. HOMA correlated positively with RBC (r= 0.17, p< 0.001), plasma hemoglobin concentrations (r= 0.14, p< 0.001), hematocrit value (r= 0.15, p< 0.001) and WBC (r= 0.17, p< 0.01). Subjects in the upper quartile of IR had higher levels of plasma glucose, fasting insulin, triglycerides, hematocrit, hemoglobin, RBC and WBC count than those in the lower quartile. In conclusion, IR seems to be associated with alterations in several hematological parameters. These hematological alterations may be considered an indirect feature of the IR syndrome. Já foi demonstrado que a resistência à insulina (RI) está associada com a estimulação de progenitores eritrocitários e com níveis aumentados de marcadores inflamatórios. Desta maneira, a RI pode também estar associada o aumento de hemácias e leucócitos. Esse estudo objetivou demonstrar que a RI está independentemente associada com a alteração de parâmetros hematológicos em uma amostra da população brasileira. Nós analisamos exames laboratoriais de 925 indivíduos, incluindo todos os dados de parâmetros hematológicos, resistência insulínica (homeostasis model assessment -HOMA) e níveis lipídicos. Informação demográfica incluiu idade e gênero. HOMA correlacionou-se positivamente com a contagem de eritrócitos (r= 0,17; p<0,001), a concentração de hemoglobina (r= 0,14; p<0,001), o hematócrito (r= 0,15; p<0,001) e a contagem de leucócitos (r= 0,17; p<0,01). Indivíduos no quartil superior de RI tinham níveis mais elevados de glicemia, insulina de jejum, triglicérides, hematócrito, hemoglobina e contagem de leucóci-tos e eritrócitos do que aqueles no quartil inferior. Em conclusão: a RI parece estar associada com alterações em diversos parâmetros hematológicos. Essa alterações hematológicas podem ser consideradas um achado indireto da síndrome de resistência insulínica.

OCT is a new method that can help the evaluation of ME in diabetic patients. It can be used not only to diagnose the lesion, but also to follow up the patients during treatment. High levels of haemoglobin A1c might be associated with the presence of ME. Diabetic complications (nephropathy and neuropathy) are associated with retinopathy but not with macular edema.

SUMMARYAtypical presentation forms of hyperthyroidism are always a challenge to the clinician. We pre sent a female patient with the typical symptoms of thyrotoxicosis, without any thionamides treatment before, associated with pancytopenia, which recovered after euthyroidism state was achieved. Although the major cases of pancytopenia in Grave's disease are seen as a compli cation of antithyroid drugs (thioamides), in this case report the alteration in blood tests was associated with untreated hyperthyroidism. In the literature review, we found 19 case reports between 1981 to 2012, but it has been related to a hypercellular bone marrow with periferic destruction. Our case, however, is about a hypocellular bone marrow without fibrosis or fat tissue replacement, which proceeded with a periferic improvement following thyroid treatment. Although rare, pancytopenia, when present, may develop as an unusual and severe manifesta tion in untreated subjects.

Apresentamos uma paciente do sexo feminino, com sintomas típicos de tireotoxicose associa do a um quadro de pancitopenia sem nenhum tratamento prévio com tionamidas. A melhora da alteração hematológica ocorreu após recuperação do eutireoidismo. Embora a maioria dos casos de pancitopenia na doença de Graves seja uma complicação das drogas antitireoidianas (tionamidas), neste caso a alteração hematológica foi associada ao quadro de hipertireoidismo não tratado. Após uma revisão na literatura, encontramos 19 relatos de caso descritos no perío do de 1981 a 2012, nos quais o quadro de pancitopenia estava relacionado à hipercelularidade medular com destruição periférica das células sanguíneas. Nosso caso, entretanto, tratase de uma pancitopenia com medula óssea hipocelular, sem infiltração por tecido adiposo ou fibrose, que evoluiu com melhora dos elementos do sangue periférico após tratamento do hipertireoi dismo. Embora rara, a pancitopenia, quando presente, pode se manifestar como uma severa manifestação se não tratada a condição desencadeadora. Arq Bras Endocrinol Metab. 2014;58(9):953-7

The objective of the present study was to establish the frequency of psychiatric comorbidity in a sample of diabetic patients with symmetric distal polyneuropathy (SDPN). Sixty-five patients with type 2 diabetes mellitus were selected consecutively to participate in the study at Instituto Estadual de Diabetes e Endocrinologia. All patients were submitted to a complete clinical and psychiatric evaluation, including the Portuguese version of the structured clinical interview for DSM-IV, the Beck Depression Inventory, the Neuropathy Symptom Score, and Neuropathy Disability Score. SDPN was identified in 22 subjects (33.8%). Patients with and without SDPN did not differ significantly regarding sociodemographic characteristics. However, a trend toward a worse glycemic control was found in patients with SDPN in comparison to patients without SDPN (HbA 1c = 8.43 ± 1.97 vs 7.48 ± 1.95; P = 0.08). Patients with SDPN exhibited axis I psychiatric disorders significantly more often than those without SDPN (especially anxiety disorders, in general (81.8 vs 60.0%; P = 0.01), and major depression -current episode, in particular (18.2 vs 7.7%; P = 0.04)). The severity of the depressive symptoms correlated positively with the severity of SDPN symptoms (r = 0.38; P = 0.006), but not with the severity of SDPN signs (r = 0.07; P = 0.56). In conclusion, the presence of SDPN seems to be associated with a trend toward glycemic control. The diagnosis of SDPN in diabetic subjects seems also to be associated with relevant psychiatric comorbidity, including anxiety and current mood disorders.

O diabetes é uma doença muito prevalente e  com múltiplas vias patogênicas. Diversos fenótipos compõe o espectro dessa doença, alguns clinicamente semelhantes, como o “Latent Autoimmune Diabetes of the Adult” (LADA) e o "Double Diabetes" (DD), dificultando  diagnóstico e manejo clínico. Em ambas apresentações, ocorre uma intersecção de características típicas do diabetes tipo 1 (DM1) e tipo 2 (DM2). Relata-se o caso de uma paciente de 44 anos, que iniciou quadro de diabetes gestacional há 20 anos. Após dois anos sem tratamento, apresentou emagrecimento, polidipsia e diplopia, associadas a anti-GAD positivo, sendo diagnosticada como DM1. Ao procurar o ambulatório a paciente apresentava quadro de Síndrome Metabólica. Este trabalho visa discutir o complexo diagnóstico do diabetes. Embora esta seja uma doença muito estudada, a cada nova evidência científica, um antigo conceito "cai por terra" e percebe-se o quão leigos ainda somos quando se trata de diabetes.
