Availability and Access to Medications for Puberty Induction and Maintenance in Adolescents with Hypogonadism in the Arab Region.

Background: Inducing puberty in hypogonadal patients enables achieving normal final adult height and healthy bone mass accrual and improves fertility potential. Reliable availability and access to medicines remain a challenge around the world, particularly in low-income countries. Aim: We aimed to describe the availability/access to medications used for inducing and maintaining puberty in centers within the Arab region. Method: A cross-sectional survey was conducted using a link to an online questionnaire, which was emailed to paediatric endocrinologists in the Arab region. The questionnaire consisted of three questions related to the availability of various forms of sex hormones. Results: 99 physicians from 16 countries participated in the study. The commonest available form of estrogen was conjugated estrogen (29% of centers), followed by ethinylestradiol (26%). Depot estradiol was available in 11 centers, while topical estrogen preparations of gel and patches were available in 6 and 10 centers, respectively. Medroxy progesterone was available in 26% of the centers, followed by norethisterone (24%). The combined forms of oral and transdermal patches of estrogen/progesterone were available in 35% and 9% of centers, respectively. Intramuscular testosterone (Sustanon) was the most commonly available preparation of testosterone, followed by the depot injection (Nebido), oral testosterone, and testosterone gel and cream. Conclusions: We report the first available data on medications used for puberty induction and maintenance in paediatric hypogonadism in the Arab region. Recommended preparations for this purpose are not widely available. Creating an essential list of medications used in paediatric endocrinology disorders might improve availability, access, and consequently practice.

Assessment of serum acylated ghrelin in children and adolescents with chronic liver diseases: relation to nutritional status.

Because ghrelin is one of the key hormones in regulating feeding behavior and caloric status, it was suggested that ghrelin behavior might be closely associated with malnutrition state of patients with chronic liver disease (CLD). Thus, we aimed to assess serum ghrelin levels in children with CLD and its relation to anthropometric parameters and severity of CLD. Forty CLD patients were studied in comparison to 40 controls. All subjects were subjected to history, anthropometric, and laboratory assessment of liver functions and serum acylated ghrelin. Ghrelin was higher in patients than controls being higher with progress of Child's grade and with deterioration of liver functions. Hyperghrelinemia was detected in 62.5% of cases. Ghrelin correlated negatively with body mass index standard deviation score (BMISDS (r = -0.95, P < 0.001)), triceps skin fold thickness (TSFT (r = -0.88, P < 0.001)), and subscapular skin fold thickness (SSFT (r = 0.83, P < 0.001)) percentiles. In conclusion, hyperghrelinemia may represent a compensatory mechanism trying to overcome malnutrition state complicating CLD and can be used as a parameter for early detection and assessment of the severity of malnutrition in children with CLD.

Surgical and functional outcomes of sigmoid vaginoplasty among patients with variants of disorders of sex development.

PURPOSE: To assess the use of sigmoid colon in vaginal reconstruction of some patients with disorders of sex development. MATERIALS AND METHODS: The study included 31 patients with disorders of sex development of various causes. All were reared as females. Female gender was decided for all cases after complete medical assessment. All patients underwent sigmoid vaginoplasty. Assessment of surgical and functional outcomes was carried out in a follow-up period of up to 6 years. RESULTS: The preoperative diagnoses included mullerian aplasia (16 cases), androgen insensitivity syndrome (12 cases) and previous failed vaginoplasty (3 cases). Associated surgical procedures were gonadectomy in 5 cases and gonadectomy combined with clitoroplasty and vulvoplasty in 7 cases. No intra-operative or early postoperative complications occurred. A cosmetic neovagina with adequate size was achieved in all cases. Long term follow-up showed introital stenosis in 4 cases (12.9 %). Two of them responded to vaginal dilatation. The third one needed y-v plasty while the fourth one presented by acute abdomen secondary to ruptured vagina and was submitted to urgent laparotomy. Mucosal prolapse occurred in 1 case (3.2 %). Reoperation rate was 9.6 %. Sexual satisfaction was achieved among 9 sexually active cases. The subjective satisfaction score of the surgical outcome was 8.03. CONCLUSIONS: For patients with disorders of sex development of various etiologies, sigmoid vaginoplasty is the preferred technique for vaginal replacement. It is a safe technique that provides the patient with a cosmetic neovagina of adequate caliber and a satisfactory functional outcome.

Adrenal function in thalassemia major adolescents.

BACKGROUND: Several studies reported a significant prevalence of adrenal insufficiency, ranging from 18-45%, in patients with thalassemia. Evidence for dissociation of cortisol and adrenal androgen secretion in patients with beta-thalassemia was previously reported. AIM: We measured adrenal androgen response along with cortisol to the standard (250 mg) dose ACTH test. METHODS: Forty five beta-thalassemia major (TM) patients were enrolled. Their ages ranged between 12 and 20 years (14.9 ± 2.2 years). All patients underwent the 250 mg cosyntropin test in the morning before blood transfusion. Blood samples for total cortisol, dehdroepiandrosterone (DHEA) and androstendione (A) measurements were collected before and 60 min after IV injection of 250 mg cosyntropin. Adrenal insufficiency was observed in 7 of 45 (15.5%) patients. Adrenal androgen levels decreased significantly with advancing Tanner stage. No difference was noted between patients with and without adrenal insufficiency regarding anthropometric and laboratory parameters. CONCLUSION: Adrenal insufficiency is not a rare complication in thalassemia. Adrenal androgen production declines with advancing puberty in thalassemic adolescents and might explain the poor development of pubic and axillary hair observed in this condition.
