Keywords: Central Precocious Puberty, Girls, Peripheral, IdiopathicBackground: Precocious puberty is thought to occur in 1 in 5000–10,000 people. Precocious puberty is a neglected topic in Pakistan, and little research has been done so far to examine its aetiology in our population, despite its importance and relative prevalence.Objective: To find the frequency of precocious ...

Background: Congenital hypothyroidism (CH) is a common and preventable cause of mental retardation in children, and is detected using dried blood spots in many neonatal screening programs. Upon suspicion of CH, plasma free thyroxine (FT4) and thyroid stimulating hormone (TSH) concentrations are measured. CH can be of thyroidal or central origin (CH-T and CH-C, respectively). While CH-T diagnosis is based on an elevated plasma TSH in combination with a low FT4,...

Background: Patients with a mutation in the thyroid hormone (TH) receptor TRα1 are characterized by growth retardation, delayed bone development, mild cognitive defects and constipation. They also have abnormal TH levels: low FT4, high T3, and low rT3 levels, suggesting an altered peripheral TH metabolism by deiodinases. The type 3 deiodinase (D3) inactivates TH by catalyzing the degradation of T3. D3 is importantly expressed in...

Background: Measurement of testicular volume is important when conditions associated with a delay or advance in the onset of puberty, or micro- and macroorchidism, are suspected. Measured testicular volumes must be compared with reference data, preferably expressed in S.D. curves using the LMS method, as is routinely done for many auxological measurements in pediatrics. The current study therefore aimed to construct LMS-smoothed age-reference charts for testicul...

Background: Although motor performance is often impaired in patients with Turner syndrome, the exact prevalence of motor problems is unknown. Detailed studies on specific motor profiles are lacking and the exact relationship between performal IQ and motor function is unknown.Aims and objectives: 1. To describe motor performance in our population of children and adolescents with Turner syndrome including the differentiation in specific motor skill domains...

Background: Thyroidectomy is a definitive treatment option in some benign thyroid disorders and the definitive treatment option for thyroid cancer. As postoperative mortality is extremely rare data on postoperative complications and long-term health consequences are important.Objective: To evaluate the frequencies of short- and long-term complications, and their risk factors in pediatric patients (0-18 years) who underwent a thyroidectomy in a tertiary c...

Introduction: Childhood craniopharyngioma (cCP) has excellent survival, but quality of life may be severely hampered by hypothalamic dysfunction. We aimed to evaluate treatment and hypothalamic outcomes of a Dutch cCP cohort, and evaluate the effect of centralization of care.Methods: A retrospective cohort study was performed, including cCP patients diagnosed between 2004-2021. Treatment characteristics and hypothalamic ...

Introduction: Patients carrying homozygous IGF1 loss-of-function mutations are extremely rare and show severe pre- and postnatal growth failure, microcephaly, developmental delay, retrognathia and sensorineural deafness. Heterozygous variants in IGF1 appear to be more common in short stature, but only few cases have been reported in detail. Therefore, clinical features and growth response to recombinant human growth hormone (rhGH) therapy are...

CHARGE syndrome is a rare and complex disorder with an incidence of 1:15000 to 1:17000 live births. It is associated with a wide range of issues, including, but not limited to, coloboma of the eye, congenital heart disease, atresia of the choanae, retardation of growth and development, hypogonadotropic hypogonadism, ear abnormalities and hearing loss. Hypogonadotropic hypogonadism is present in 60-88% of individuals with CHARGE syndrome. In these patients, hormone replacement ...

Background: Pseudoisodicentric X chromosomes with an Xq deletion (46,X,idic(Xq)) are rare. Most cases are mosaic, the other cell line being 45,X. Nonmosaicism is rare. Phenotype is characterized by the resultant of the X deletion. Variations from short to tall stature can occur and premature ovarian failure is a common feature.Case presentation: A 16 year old girl was referred to our clinic with primary amenorrhoea. She ...
