Acromegaly Presenting With Cricoarytenoid Joint Arthropathy

The Laryngoscope, EarlyView.
Excess growth hormone in acromegaly induces characteristic acral and soft tissue overgrowth (particularly in the face and hands), arthropathies, as well as cardiovascular and metabolic complications. Similar proliferative changes can occur in the larynx, where hypertrophy of the arytenoid and cricoid cartilages may impair vocal fold mobility.

Causal associations of COVID‐19 on neurosurgical diseases risk: a Mendelian randomization study

Human Genomics
Many researchers have explored the potential association between one neurosurgical disease and coronavirus disease 2019 (COVID-19), but few systematically analyzed the association and causality between COVID-19 and various neurosurgical diseases.

Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Thyroxine-binding globulin: investigation of microheterogeneity [PDF]

, 1981
Preparations of T4-binding globulin (TBG) from human serum was performed using only two affinity chromatography steps. Purity of the protein was demonstrated by a single band in overloaded disc and sodium dodecyl sulfate electrophoresis, equimolar ...

Evaluating the Link Between Thyroid Function Test Results and Levothyroxine Dose in the Management of Hypothyroidism: Can We Improve Dosing Regimes?

Clinical Endocrinology, EarlyView.
ABSTRACT Introduction Over 10 million thyroid function tests (TFTs) are carried out in England each year, most requests coming from primary care. Our previous work showed that only 25% of results for patients being treated with Levothyroxine fell within the TSH/FT4 boundary circumscribing 75% of untreated individuals.

Clinical Practice Patterns in Bone Health Assessment and Management in Endogenous Cushing's Syndrome

Clinical Endocrinology, EarlyView.
ABSTRACT Objective Skeletal fragility is a common complication of endogenous Cushing's Syndrome (CS), although specific guidelines for managing bone health are lacking. This study aimed to assess clinicians' current engagement with bone health assessment and management in patients with endogenous CS. Design Retrospective‐cohort design. Patients Seventy‐

No evidence for oncogenic mutations in guanine nucleotide-binding proteins of human adrenocortical neoplasms [PDF]

, 1933
G-Proteins are membrane-bound heterotrimeric polypeptides that couple receptor signals to second messenger systems such as cAMP. Recently, point mutations at 2 codons of the highly preserved alpha-chain of Gs, the adenyl cyclase-stimulating G-protein ...
