Introduction: Intraoperative identification of neck lesions in patients who have undergone previous neck surgery is particularly difficult, because of operative scarring and distorted anatomy. Radioguided occult lesion localisation (ROLL) involves the preoperative intratumoral ultrasound-guided injection of a radioactive tracer. In the present study, we investigated the efficacy of roll in two patients with papillary thyroid cancer (PTC) who underwent previous neck exploration...

Thirty-two years old female G2P1A0 seen at our endocrinology clinic 9 years ago complaining of persistent menstrual irregularities associated to elevated prolactin values. MRI done revealed a pituitary microadenoma. However, she refused treatment for microprolactinoma. Four years afterwards, patient return complaining of recurrent episodes of headache. Repeated MRI showed a pituitary macroadenoma, so start on cabergoline treatment.Once more, patient was ...

Background: Most thyroid specific genes are transcriptionally regulated by TSH-TSHR signalling and T4-driven negative feedback of TSH secretion at the pituitary. However, local autoregulation of transcription has been described from IGF-IGFR, follicular thyroglobulin, or iodine. We aimed to investigate the TSH dependency of thyroid transcriptional regulation in the Dehal1 knockout, devoid of iodide-recycling capacity from iodotyrosines.Methods: ...

Background: Low plasma aldosterone after adrenalectomy due to aldosterone-producing adenoma (APA) and postoperative hypoaldosteronism recovery have been well described. However, prospective time course comparing simultaneously aldosterone and renin levels is still lacking.Aim: We prospectively studied clinical and biochemical findings emphasizing aldosterone and renin levels, in a cohort of patients with APA who underwent adrenalectomy in a single tertia...

Objective: While osteoporotic fractures are reported in up to 40% of post-poliomyelitis adults, clinical guidelines regarding bone mineral density (BMD) testing and best timing for initiating treatment in this population are scarce. We assessed the characteristics of post-poliomyelitis patients, focusing on fracture and osteoporosis as the primary outcomes.Methods: We conducted a cross-sectional retrospective data analysis from medical records of 204 pos...

Background: Pancreatic Cancer (PC) is uncommon; however, it is one of the most deadly cancer types of all. New-onset diabetes (NOD) is associated with a higher risk of pancreatic cancer than general population, particularly if late-onset. An association between new-onset diabetes and increased mortality in patients with pancreatic cancer has been suggested but clinical relevant differences between those individuals with new-onset diabetes and those without are not well establi...

Bariatric surgery (BS) improves quality of life and health due to the beneficial effect on the metabolism at multiple levels. Specifically, its effectiveness in weight loss and the attenuation or resolution of comorbidities associated with obesity, means lower morbidity and mortality compared to other types of interventions. The objective is to analyze the evolution of obesity-related diseases after twelve months of follow-up.Methods: Retrospective study...

Background: AMH represents a marker of ovarian reserve and is used in monitoring the effects of gonadotoxic drugs. In PCOS is higher and is an indirect marker of hyperandrogenism. In transsexual man(TM), high prevalence of PCOS is described and AMH provide information about ovarian reserve after exposure to testosterone.Objective: To assess the prevalence of PCOS in young TM previously to testosterone treatment, study the evolution of AMH levels and diff...

Objective: Althoughmost Papillary Thyroid Cancer (PTC) patients with biochemical incomplete response (BIR) to primary therapy have a good clinical outcome, some will develop disease progression. We aim to study baseline characteristics and long-term outcomes of PTC patients with BIR.Methods: Of 1049 PTC patients treated at 2 tertiary medical centers, 795 (75.8%) had excellent, 91 (8.7%) biochemical incomplete, 139 (13.2%) structural incomplete and 24 (2....

Introduction: It is universally accepted that calcitonin (CT), a hormone secreted by the parafollicular cells of the thyroid, is a specific, sensitive and early marker of Medullary Thyroid Carcinoma (CMT), with higher diagnostic accuracy than fine needle aspiration biopsy(FNAB). However, the routine measurement of serum CT during assessment of nodular thyroid disease (NTD) remains controversial due to rarity of this cancer and possible false positive results.<p class="abst...
