CONTEXT Differentiated thyroid cancer (DTC) in thyroglossal duct cysts is uncommon. The requirement of total thyroidectomy and lymph node dissection is still controversial. SETTING The study was performed in a referral thyroid cancer center at an academic hospital. PATIENTS We conducted a single center retrospective study of a consecutive series of 26(More)
CONTEXT Treatment and follow-up of patients thyroidectomized for differentiated thyroid carcinoma (DTC) mainly depends on the identification of the patient's risk of recurrence. Thyroglobulin (Tg) is the most important marker of persistent/recurrent disease. The recent introduction of a new, more sensitive Tg measurement allows for the early detection of(More)
CONTEXT Levothyroxine monotherapy is the treatment of choice for hypothyroid patients because peripheral T4 to T3 conversion is believed to account for the overall tissue requirement for thyroid hormones. However, there are indirect evidences that this may not be the case in all patients. OBJECTIVE To evaluate in a large series of athyreotic patients(More)
Ten chronic undifferentiated schizophrenics, 6 men and 4 women, aged 28-63, with 6- to 31-year histories of the disease were given DDAVP to observe the effects of this neuropeptide on the prevalent negative symptoms of their illness. Patients were maintained on neuroleptic therapy and first given a 20-day course of placebo followed by 20 days of DDAVP i.m.,(More)
CONTEXT Medical centers worldwide report an increased frequency of Hashimoto's thyroiditis (HT) and thyroid cancer (TC), two environmentally influenced diseases. In Sicily, data on HT are available for the province of Messina (1975-2005); data on TC are available for the whole island (2002-2004), with the volcanic province of Catania having the highest(More)
INTRODUCTION In genetically predisposed individuals, exogenous factors (including pollution) influence the development of Hashimoto's thyroiditis/chronic lymphocytic thyroiditis (CLT). CLT may also be a risk factor for associated thyroid cancer. Few data are available on the role of pollution from petrochemical complexes, one of which is located in the(More)
Necrobiosis lipoidica (NL) is a degenerative disease of dermal connective tissue of unknown etiology characterized by erythematous plaques preferentially localized to distal extremities. Skin lesions show a chronic relapsing nature. NL is often associated with diabetes mellitus and satisfactory treatment options are lacking. We describe the spontaneous(More)
BACKGROUND Whether serum TSH undergoes seasonal fluctuations in euthyroid and hypothyroid residents of temperate climates is controversial. METHODS Monthly TSH and thyroid hormone levels were cross-sectionally analysed in a large cohort of euthyroid subjects (n=11 806) and L-thyroxine (L-T4)-treated athyreotic patients (n=3 934). Moreover, in a small(More)
OBJECTIVE To characterize primary hyperparathyroidism (PHPT) patients with renal stones and to compare silent with symptomatic stone formers. METHODS We reviewed clinical data from 234 patients with PHPT, comparing those with and without renal stones (n = 109 and 125, respectively), and among stone formers those symptomatic versus silent (n = 93 and 16,(More)
