Context: Congenital hypogonadotropic hypogonadism (CHH) is defined as an isolated deficiency of gonadotropin hormones. Mini-puberty, a transient postnatal activation of the hypothalamic-pituitary-gonadal axis in healthy infants, provides a window of opportunity to diagnose and treat CHH. Currently, in male infants with CHH, testosterone is used to increase phallus size.

However, so far only ex situ studies of the synthesis are performed, mostly due to the difficulty of handling HF-based solutions. Here the first time-resolved in situ synchrotron radiation X-ray Diffraction study of MXene synthesis performed using a plastic capillary-size reaction cell directly in HF solution is reported.

Methods: As part of a larger follow-up study performed between the years 2002-2005 there were questionnaires concerning genital surgery, type of surgery, their thoughts about timing of genital surgery and experience of information about surgery. Early surgery was defined as ≤4 years of age and late ≥10 years.
Introduction: Partial androgen insensitivity syndrome (PAIS) is a rare condition that is reported to be commonly associated with gynecomastia in males.
Objectives: To assess the management of gynecomastia in male PAIS.
Materials And Methods: Retrospective review of males with PAIS over the age of 10 years in the I-DSD registry.
Objective: To study school achievement in grade 9 of compulsory school in children with congenital hypothyroidism (CH), both those detected by the national screening program and those with a normal screening result and thus diagnosed later.
Study Design: Nationwide study of children in the Swedish Medical Birth Register (n = 1 547 927) from 1982 through 1997, linked to the neonatal screening CH cohort and the National School Register. Dried blood spot (DBS) samples are collected from all newborn infants, according to the neonatal screening program.
There are 3 physiological waves of central hypothalamic-pituitary-gonadal (HPG) axis activity over the lifetime. The first occurs during fetal life, the second-termed "mini-puberty"-in the first months after birth, and the third at puberty. After adolescence, the axis remains active all through adulthood.

Objective: To study the prevalence of injuries and accidents in females and males with CAH.
Design, Setting, And Participants: Patients with CAH (n = 714, all 21-hydroxylase deficiency) were compared with matched controls (n = 71 400).
Background: Complications are frequently reported after hypospadias repair and there is a need to understand the factors that influence their occurrence.
Methods: Data from boys with hypospadias born between 2000 and 2020 were obtained from the International Disorders of Sex Development (I-DSD) Registry. Logistic regressions, fisher's exact tests and spearman's correlation tests were performed on the data to assess associations between clinical factors and complication rates.
Objective: This study aims to evaluate the neonatal screening for congenital hypothyroidism (CH) and the diagnosis CH in the national health registers and to study the effects of lowering screening thyroid-stimulating hormone (TSH) threshold on the incidence of CH and birth characteristics of screening positive and negative CH children.
Design: This is a nationwide register-study of all children (n = 3 427 240) in the Swedish Medical Birth Register (MBR) and national cohort for screening positive infants (n = 1577) in 1980-2013.
Methods: The study population was further linked to several other Swedish health registers.
Objective: Congenital adrenal hyperplasia (CAH) refers to a group of genetic disorders that affect cortisol biosynthesis and the need for glucocorticoid treatment is lifelong. The complexities of CAH can greatly affect teenage life and the transition from pediatric to adult care. The aim was to assess transition readiness and the impact on quality of life (QoL) as well as medication adherence rates in adolescents and young adults with CAH.
View Article and Find Full Text PDFCongenital adrenal hyperplasia is a group of autosomal recessive disorders leading to multiple complex hormonal imbalances caused by various enzyme deficiencies in the adrenal steroidogenic pathway. The most common type of congenital adrenal hyperplasia is due to steroid 21-hydroxylase (21-OHase, henceforth 21OH) deficiency. The rare, classic (severe) form caused by 21OH deficiency is characterised by life-threatening adrenal crises and is the most common cause of atypical genitalia in neonates with 46,XX karyotype.

Here we demonstrate that pine cones, an abundant bio-precursor currently considered as a waste in the wood industry, can be used to prepare activated carbons with a BET surface area exceeding 3000 m g. It is found that the same KOH activation procedure applied to reduced graphene oxide (rGO) and pine cone derived biochars results in carbon materials with a similar surface area, pore size distribution and performance in supercapacitor (SC) electrodes.

As with other patient-reported experiences, they can complete the clinical evaluation and management of a specific disease, improving the often long diagnostic delay, therapy, patient education and access to knowledgeable multidisciplinary teams. This review discusses the utility of such patient-reported experience measures and summarises the experiences of patients with acromegaly, Addison's disease and congenital adrenal hyperplasia from different European countries.

Here we report an irreversible swelling transition, which occurs in MXenes immersed in excess dimethyl sulfoxide (DMSO) upon heating at 362-370 K with an increase in the interlayer distance by 4.2 Å.
View Article and Find Full Text PDFA plethora of negative long-term outcomes have been associated with congenital adrenal hyperplasia (CAH). The causes are multiple and involve supra-physiological gluco- and mineralocorticoid replacement, excess adrenal androgens both intrauterine and postnatal, elevated steroid precursor and adrenocorticotropic hormone levels, living with a congenital condition as well as the proximity of the cytochrome P450 family 21 subfamily A member 2 (CYP21A2) gene to other genes. This review aims to discuss the different long-term outcomes of CAH.

Objective: Congenital adrenal hyperplasia (CAH) requires exogenous steroid replacement. Treatment is commonly monitored by measuring 17-OH progesterone (17OHP) and androstenedione (D4).
Design: Retrospective cohort study using real-world data to evaluate 17OHP and D4 in relation to hydrocortisone (HC) dose in CAH patients treated in 14 countries.
Mini-puberty is defined as the period in infancy with elevated FSH and LH resulting in increased levels of sex hormones. It differs between boys and girls and its impact on future fertility is not completely known. This mini-review focus on the effects of mini-puberty on genital development and some aspects possibly related to future fertility.

It remains challenging to prevent the excessive exposure of DEX in unborn healthy babies during the first trimester of pregnancy.
Objective: Since endogenous glucocorticoids contribute to the maintenance of blood pressure (BP) and since events during fetal life may program the fetus and affect future metabolic health, the aim of this study was to analyze ambulatory BP measurements in CAH-unaffected children and adults that were prenatally exposed to DEX treatment.

Background: The standard treatment for congenital adrenal hyperplasia (CAH) in children is still hydrocortisone. Improved strategies for timing of the dose during the day and the dose per square meter body surface area used in children of different ages and developmental phases have improved the situation and outcome for the patients. Neonatal screening enables an earlier diagnosis and initiation of treatment, prevents from adrenal crisis, and improves growth and development also for children with the less severe forms of CAH.
