RESUMEN
Pancreatic metastases of papillary thyroid carcinoma (PTC) are exceptional. We report a 80-year-old man consulting for obstructive jaundice and dysphonia. Abdominal ultrasonography showed biliary dilation and abdominal magnetic resonance imaging (MRI) showed a pancreatic head mass of 36 mm. A left vocal cord paralysis was confirmed and cervical computed tomography (CT) showed multiple thyroid nodules of up to 35 mm associated with bilateral cervical lymph nodes (LN). Positron emission tomography ( 18 F-FDG PET/CT) evidenced hyper-metabolic activity in bilateral cervical LN, lungs, pancreas and left intercostal soft tissue, as well as left gluteus. Thyroid biopsy reported a tall-cell variant of PTC, and endoscopic ultrasound guided fine needle aspiration (EUS-FNA) of pancreatic mass confirmed PTC metastasis. The molecular study was positive for BRAFV600E. Pancreatic metastasis from PTC can be accurately diagnosed with 18 F-FDG PET/CT and EUS-FNA, which is consistent with a predominant expression of BRAFV600E mutation and, thus, an aggressive presentation with poor short-term survival.

Background: Few studies have evaluated the details of insulin therapy for type 1 diabetes mellitus (T1D) in Chile. Aim: To describe clinical features and treatment details of adults with T1D and its association with metabolic control. Material and Methods: Review of medical records of patients with T1D treated in a clinical network. Demographic and clinical features, types and doses of insulin and glycated hemoglobin levels were registered. The use flash glucose monitors (FGM) and insulin pumps (CSII) were also recorded. Results: 205 records were reviewed, with T1d lasting 12 ± 10 years. Twenty six percent had hypothyroidism, 1% had celiac disease, 12% had hypertension, 20% had dyslipidemia; 13% had diabetic retinopathy, 2% had diabetic nephropathy, 8% had neuropathy and 2% cardiovascular diseases. Mean body mass index was 25 kg/ m2 and mean glycated hemoglobin was 8%. Eighty-two percent used multiple daily injections, 18% used CSII and 24% used FGM. As basal insulin, 35% used slow acting analogs and 65% used ultra-slow analogs. As rapid acting insulin, 69 patients used Lispro, 79 Aspart and 50 Glulisin. Bolus doses were calculated using only capillary glucose in 22%, while 78% also considered carbohydrate consumption. Variables significantly associated to better control were the use of carbohydrates for dosing rapid insulin (A1c 7,85% vs 8,59%, p = 0,008), use of CSII (A1c 7,36% vs 8,16%, p = 0,008), and basal dose < 0,4 U/kg (A1c 7,81% vs 8,58%, p = 0,003). There were no differences regarding insulin type or use of FGM. Conclusions: The use of formulas considering carbohydrates for dosing rapid insulin, use of infusion pumps and physiological doses of basal insulin are significantly associated with a better metabolic control in adults with T1d.
