Airway Remodeling in Cystic Fibrosis Is Heterogeneous.

RATIONALE+OBJECTIVE/ Cystic fibrosis (CF) is characterized by bronchiectasis on imaging, while functionally evolving towards obstructive impairment. Despite its assumed importance in CF, small airway remodeling and its relation to bronchiectasis, is still poorly understood. METHOD/ On high-resolution computed tomography (HRCT, 600µm, CF=21, control=6) and micro-computed tomography (µCT, 150µm, CF=3, control=1) scans of inflated explant lungs, AV% (airway/total lung volume) was calculated as marker for bronchiectasis, while airway segmentation was used for generation analysis.

Growth Hormone-Secreting Pituitary Adenoma: Dura Mater Invasion Is Not a Predictor of Acromegaly Persistence After Trans-Sphenoidal Surgery.

: In pituitary adenomas, examinations of surgical specimens have shown that dural invasion occurs in 42-85% of cases. No studies about dura mater invasion have been conducted specifically in acromegaly patients. The aim of the present study was to evaluate the relationship between histologically dural invasion and the main features of GH-secreting adenomas.

Treatment with Long-Acting Somatostatin Analogues in Patients with Acromegaly: When and How.

Somatostatin and its analogs have been for years a mainstay treatment for a variety of hypersecretory conditions and neoplasms of the endocrine system. This chapter summarizes their pharmacological properties, their indication in the context of acromegaly, and the best way to handle this class of drugs for the treatment of the patient with acromegaly.

A 2024 Update on Growth Hormone Deficiency Syndrome in Adults: From Guidelines to Real Life.

Adult growth hormone deficiency (GHD) has been recognized since the late 1980s. The clinical manifestations of adult GHD are often nonspecific, and diagnosis relies on GH stimulation tests, which are intricate, costly, time-consuming, and may carry the risk of adverse effects. Diagnosis is further complicated by factors like age, sex, and BMI, which affect GH response during testing.
