During development, gonadotropin releasing hormone (GnRH) neurons are born in the nasal placode and migrate to the hypothalamus, where they position to regulate sexual reproduction by pulsatile release of GnRH. Defective GnRH neuron development or action may lead to GnRH deficiency (GD) which is characterized by absent or delayed puberty. Several GD causative genes have been identified so far, but half of the cases are still idiopathic. The employment of complementary research...

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Background: Recurrence of craniopharyngiomas influences mortality. Apart from the extent of surgical resection, few clinical parameters have been consistently shown to be associated with recurrence. Radical resection is difficult due to infiltration of surrounding tissue and unacceptable morbidity. Predictors of recurrence are therefore needed.Aim: To establish a multinational cohort of patients with craniopharyngioma an...

Cerebral infarction in childhood-onset craniopharyngioma patients: results of KRANIOPHARYNGEOM 2007

Boekhoff Svenja , Bison Brigitte , Genzel Daniela , Eveslage Maria , Otte Anna , Friedrich Carsten , Flitsch Jorg , Muller Hermann L. ,

Background: Cerebral infarction (CI) is a known vascular complication following treatment of suprasellar tumors. Risk factors for CI, incidence rate, and long-term prognosis are unknown for patients with childhood-onset craniopharyngioma (CP).Methods: MRI of 244 CP patients, recruited between 2007 and 2019 in KRANIOPHARYNGEOM 2007, were reviewed for CI. Risk factors for CI and outcome after CI were analyzed.<p class=...

Bardet-Biedl Syndrome: A retrospective study of progression through puberty

Whitehead Jennifer , Schoeneberg Dillon , Sparks Kathryn , Forsythe Elizabeth , Beales Philip , Peters Catherine , Dastamani Antonia , Katugampola Harshini ,

Introduction: Bardet-Biedl syndrome (BBS) is a rare, pleiotropic, autosomal recessive disorder, with prevalence between 1 in 100,000 – 160,000 in Europe and the USA. It is characterised by 6 cardinal features: rod-cone dystrophy, truncal obesity, cognitive impairment, hypogonadism and genitourinary anomalies, postaxial polydactyly and renal dysfunction, as well as a plethora of secondary features spanning multiple body systems. BBS belongs to a family of ...

Efficacy and Safety of Corifollitropin Alfa in Combination with Human Chorionic Gonadotropin for Initiation or Restoration of Puberty in Adolescent Males Aged 14 to < 18 Years with Hypogonadotropic Hypogonadism

Background: Combinations of follicle-stimulating hormone (FSH) and human chorionic gonadotropin (hCG) have been successful in treating males with hypogonadotropic hypogonadism (HH). The aim of this study was to investigate the efficacy and safety of corifollitropin alfa (CFA), a long-acting FSH analog, combined with hCG to induce testicular growth and pubertal development in adolescent males with HH.Methods: This was a 6...
