Since the first description of pseudohypoparathyroidism (PHP) a remarkable clinical variability was observed. In 2016 a new classification of this group of diseases have been published by the European Network on PHP and related disorders, proposing “inactivating PTH/PTHrP signaling disorder” (iPPSD) as a new term that encompasses all the clinical entities. PHP and related disorders vary in clinical presentation and disease severity, and clinical features usually deve...

Since the first description of inactivating PTH/PTHrP signaling disorders (iPPSDs, historically named pseudohypoparathyroidism (PHP)) a remarkable clinical variability was observed, especially in clinical presentation, which seems to be age-dependent. The main clinical features, including PTH resistance, brachydactyly and short stature, develop during mid and late childhood, whilst minor clinical features such as a round face, rapid weight gain and subclinical hypothyroidism a...

Inactivating PTH/PTHrP signaling disorders (iPPSDs, historically named pseudohypoparathyroidism (PHP)) are a group of rare disorders associated with resistance to parathormone (PTH) and other hormones due to impaired hormonal signaling via G protein coupled receptors. Hypercalcitoninemia has been reported in these patients, however very few reports are available. The aim of this study was to further investigate the prevalence and characteristics of hypercalcitoninemia in both ...

Introduction: The serum calcium/phosphorus (Ca/P) ratio has been proposed to identify patients with primary hyperparathyroidism and chronic hypoparathyroidism (HPT) from healthy subjects. However, other disorders of the Ca-P metabolism might present similar biochemical profile of HPT, such as pseudohypoparathyroidism (PHP), for which the use of Ca/P can be useful. Aim: To test the performance of Ca/P ratio in the diagnosis of PHP in comparison to healthy...

The aim of this study was to evaluate in a long follow-up time patients with acromegaly successfully treated by transphenoidal surgery (TNS) in order to establish the recurrence rate and the need of subsequent follow up.Methods: We retrospectively analyzed data of 283 acromegalic patients (168 females, mean age: 44.2 ±12.9 years) who underwent TNS for a GH secreting pituitary adenoma between 1980 and 2020, on regular follow-up at two Pituitary Units...
