Androgen receptor CAG repeat polymorphism might be a possible cause of familial constitutional delay of growth and puberty.

Background: Induction of puberty in boys with constitutional delay of growth and puberty (CDGP) through a short course of low-dose testosterone therapy indicates the critical interaction between testosterone and the androgen receptor (AR) during the activation and maturation of the hypothalamic-pituitary-gonadal axis at puberty onset. Previous studies have shown an inverse relationship between the CAG repeat length and the transactivation function or expression level of the AR gene.

Objective: We aimed to investigate whether the AR CAG repeat polymorphism has any implications on pubertal delay.

Avacopan in the treatment of refractory scleritis secondary to granulomatosis with polyangiitis: A case report.

Purpose: Avacopan is a novel C5a receptor inhibitor which was recently licensed for treatment of severe granulomatosis with polyangiitis (GPA) in the European Union and the United Kingdom. To the best of our knowledge, this is the first described case on initial ophthalmic outcomes in a patient with severe GPA and concurrent refractory scleritis treated with avacopan.

Case Description: We present a case of de novo scleritis in a 77-year-old male with a background of retinitis pigmentosa with Argus II implant in situ.

Diabetic cardiomyopathy: an educational review.

This educational review provides information about the epidemiology of diabetes and heart failure (diabetic cardiomyopathy) and the challenges in diagnosis and screening. Details on how to investigate patients with imaging and other modalities are discussed, as well as an update regarding the efficacy and safety of novel agents for treatment of diabetic cardiomyopathy.

Salivary Sex Steroid Levels in Infants and the Relation with Infantile Colic.

Objective: The hypothalamic-pituitary-gonadal axis is active during minipuberty, the timing of which coincides with infantile colic. To the best of our knowledge, the relationship between these entities has not been previously investigated.

Methods: Saliva samples were collected from 15- to 60-day-old term infants (n=139) between 9 am and 5 pm.
