Introduction: The importance of highly sensitive screening tests for pheochromocytoma/paragnaglioma (PPGL) is clear. However, a low level of specificity may lead to unnecessary biochemical and imaging investigations and even to needless surgical procedures. Therefore, in patients with elevated values of metanephrines, it is essential to establish a rational threshold for performing prompt thorough diagnostic investigations rather than opting for active surveillance.<p clas...

BackgroundThe term adrenal incidentaloma (AI) refers to the existence of an asymptomatic adrenal mass that was detected at random in an imaging test performed not in order to evaluate the adrenal glands. In recent years, the use of imaging tests has increased, and the resolution of the imaging studies has been improved. This trend may affect the characteristics of AIs at the time of diagnosis.ObjectiveInvesti...

Background: Data regarding the effect of gender and age on medullary thyroid cancer (MTC) presentation and prognosis is limited. Although older age and male sex were found to correlate with poorer prognosis in some studies, this correlation may reflect differences in MTC presentation between sex and age groups, or a mixture of hereditary and sporadic MTC forms.Objective: To evaluate the impact of age and sex on the presentation and outcomes of MTC.<p...

Background: The majority of adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas are less than 10 mm in diameter and are described as microadenomas, while corticotroph macroadenomas (≥10 mm) are a less common cause of Cushing’s disease. Prior reports on the differences of clinical and biochemical behavior of corticotroph microadenomas and macroadenomas were inconsistent.Objective: Describe the clinical and biochemical characteristic...

Background: Adrenocorticotropic hormone (ACTH)-producing pituitary adenoma is the most common cause of endogenous Cushing syndrome (CS), but the relative proportion of adrenal causes of CS is rising. Limited data are available on the clinical manifestations and cause of CS in older women.Objective: Determine the clinical presentation, biochemical profile, and cause of CS in women 65 years of age and older, compared with younger patients with CS.<p cl...

Background: The massive use of neck sonography has led to a dramatic increase in the incidence of thyroid cancer detection, predominantly small papillary carcinomas. However, changes in the presentation and course of medullary thyroid carcinoma (MTC) over time remain unclear.Objective: To evaluate trends in the presentation and outcomes of MTC.Methods: Patients treated for MTC at four medical centers in Israel were divided into two...

Introduction: Two aetiologies are responsible for postpartum hypopituitarism; Sheehan’s syndrome which develops following traumatic labour, and lymphocytic hypophysitis. Since management of lymphocytic hypophysitis does not require surgery in most cases, pathology is usually absent, and the clinical presentation, in combination with laboratory and imaging characteristics establish the diagnosis. We aimed to describe the various patterns of presentation, including assistin...

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: Primary hyperparathyroidism (PHPT) is the third most common endocrinopathy. Data on PHPT in the elderly are scarce.Objective: To characterize elderly patients with PHTP, clinically and biochemically.Patients: A total of 216 patients (73.6% females) aged≥75 years were diagnosed and followed at a single tertiary medical center for PHPT.Results: Mean follow-up was 11.3±5.5 years. Age at ...

Introduction: A syndrome of MEN2A and Hirschsprung’s disease described in Israeli Jews of Moroccan descent is caused by Cys 618 Arg mutation, one of the less common causes of MEN2A. We aimed to define the clinical characteristics of a large cohort with this mutation from a multi-center Israeli registry.Methods: The Israeli MTC registry including 8 centers was searched retrospectively for results of RET mutational analysis. Patients with a Cys 618 Ar...
