Both TI-RADS and the ATA guidelines have high sensitivity and NPV for the diagnosis of thyroid carcinoma. These systems are feasible for clinical application, allowing to better select patients to undergo fine-needle aspiration biopsies.

Objective. To evaluate the prevalence of chronic vascular complications and associated factors in patients with type 1 diabetes mellitus (DM 1.0, CI95%: 1.0-1.01, P = 0.05]. Seven patients had macrovascular disease. Only 22% achieved an HbA1c of <7.0%. HPT prevalence was 33%, and 48% had blood pressure levels <130/80 mmHg and 45% of the patients had LDL values > 100 mg/dl. cOnclusiOn. We observed a high prevalence of microvascular complications and HPT. The duration of DM, HPT and presence of DN were associated with DR. HPT and dyslipidemia were associated with DN. Most patients did not meet the desired glycaemic control, blood pressure and lipid targets. Greater efforts are needed to intensify the pressure and metabolic control of patients with type 1 DM.

Even though it is a rare event, most associations of thyroid carcinoma with subacute thyroiditis described in the literature are related to its granulomatous form (Quervain's thyroiditis). We present a patient with subacute lymphocytic thyroiditis (painless thyroiditis) and papillary thyroid cancer that was first suspected in an initial ultrasound evaluation. A 30-year old female patient who was referred to the emergency room due to hyperthyroidism symptoms was diagnosed with painless thyroiditis established by physical examination and laboratory findings. With the presence of a palpable painless thyroid nodule an ultrasound was prescribed and the images revealed a suspicious thyroid nodule, microcalcification focus in the heterogeneous thyroid parenquima and cervical lymphadenopathy. Fine needle aspiration biopsy was taken from this nodule; cytology was assessed for compatibility with papillary thyroid carcinoma. Postsurgical pathology evaluation showed a multicentric papillary carcinoma and lymphocytic infiltration. Subacute thyroiditis, regardless of type, may produce transitory ultrasound changes that obscure the coexistence of papillary carcinoma. Due to this, initial thyroid ultrasound evaluation should be delayed until clinical recovery. We recommended a thyroid ultrasound exam for initial evaluation of painless thyroiditis, particularly in patients with palpable thyroid nodule. Further cytological examination is recommended in cases presenting with suspect thyroid nodule and/or non-nodular hypoechoic (> 1 cm) or heterogeneous areas with microcalcification focus.
