[An update on parathyroid carcinoma].

Parathyroid carcinoma is a rare malignant disease that presents as a sporadic or familial primary hyperparathyroidism (PHP). The latter is associated with some genetic syndromes. It occurs with equal frequency in both sexes, unlike PHP caused by parathyroid adenoma that is more common in women.

Neutropenia in Incarcerated Adolescents Secondary to Intranasal Quetiapine Misuse.

Between April 2015 and May 2016, a number of young males incarcerated at a Youth Justice center in New South Wales, Australia, were noted to have unexplained and significant neutropenia. None of the adolescents were prescribed quetiapine; however, it was prescribed for other young people in the center for this time period. The authors undertook a case series review to investigate the cause of this neutropenia.

[Guidelines of the Chilean Endocrinology Society for the correct clinical use of bone densitometry].

Osteoporosis is a silent and frequent disease, which increases fracture risk. Approximately half of women and one of five men over 50 years old will suffer an osteoporotic fracture throughout their lives. Dual-energy x-ray absorptiometry (DXA) allows a real bone mineral density (BMD) measurement in different parts of the skeleton and is considered the "gold standard" for quantifying osteoporosis with high accuracy and precision.

[Positron emission tomography with fluorine-deoxyglucose in sarcomas and non-sarcoma non-epithelial tumors].

Background: The usefulness of positron emission tomography (PET) with fluorine-deoxyglucose (FDG) in sarcomas and non-sarcoma non-epithelial (NSNE) tumors is not clearly defined.

Aim: To report a Chilean experience with NSNE tumors evaluated using PET with FDG.

Material And Methods: Retrospective review of the database of a PET laboratory.

[Chilean experience with the use of 18F-deoxyglucose positron emission tomography].

Background: Clinical oncology is the main application of 18F-deoxyglucose (FDG) positron emission tomography (PET).

Aim: To evaluate the first 1,000 patients studied with FDG PET in Chile.

Material And Methods: Retrospective analysis of 1,000 patients (aged between 1 and 94 years, 550 females) studied with FDG PET, since 2003.
