Treatment of congenital hypothyroidism: comparison between L-thyroxine oral solution and tablet formulations up to 3 years of age.

OBJECTIVE: Oral solution and tablet formulations of levothyroxine (L-T4) are both used in the treatment of congenital hypothyroidism (CH). However, few studies and with a limited follow-up period have been published comparing these two formulations in children. DESIGN: The aim of this multicenter study was to compare the effectiveness of L-T4 oral solution (with ethanol as excipient) and tablet formulation in children with CH up to 3 years of age. METHODS: Children diagnosed with CH between 2006 and 2015 were enrolled and divided into two groups according to the L-T4 formulation used: solution in drops (group D) or tablets (group T). Auxological parameters, thyroid-stimulating hormone (TSH) and free thyroxine (FT4) values and L-T4 dose were collected at diagnosis and at 15 days, 1, 3, 6, 12, 24 and 36 months of treatment. The developmental quotient (DQ) at 1 and 3 years of age was evaluated using Griffiths' Scale. RESULTS: In this study, 254 children were enrolled among which 117 were treated with solution and 137 with tablets. Auxological parameters, dose and thyroid function values at diagnosis, 3, 6, 12, 24, 36 months were not significantly different. TSH at 15 days (P = 0.002) and 1 month (P = 0.009) was significantly reduced in group D. At 2-year follow-up, median TSH was significantly lower in group T (P = 0.03). No statistical difference was detected between the median DQ; however, group D showed lower values in the language subscale at 12 months and in eye-hand coordination at 36 months. CONCLUSIONS: Both therapeutic strategies are effective in the treatment of CH. A higher risk of overtreatment in the first months of therapy seems to be associated with oral solution L-T4; therefore, a different strategy should be considered when starting and adjusting the dose. No negative effects on cognitive development were observed. The data obtained are encouraging but long-term follow-up is needed.

Investigating sexuality in adolescents with cancer: patients talk of their experiences.

Objective. The aim of the present study is to understand which areas of sexuality were regarded as most important and/or problematic among adolescents with cancer.Methods. A questionnaire was administered to adolescent and young adult patients who had been receiving treatments at the Pediatric Oncology Unit of our Institution, for at least 2 months, and those in follow-up who had completed their treatments no more than two years previously. The questionnaire was devised to investigate patients' experiences in various areas, i.e. personal relations, sexual relations; functional aspects, body image, and communication.Results. Questionnaires were given to 70 patients and completed by 66. As main results, the survey showed that disease and treatment might negatively affect patients' way of relating with others (53% of cases) and their body image (56%), though their sexual desire remains unchanged (69.7%). Most patients (67%) reported not having the chance to talk to someone about having sex while receiving their treatments; 79% of patients felt this topic deserved more attention.Conclusion. This study promotes the discussion of an important topic for young people with cancer, which is inadequately addressed today. When establishing an age-specific model of care, aspects related to sexuality should be considered and managed.

Phenotypic expression of Hashimoto's thyroiditis is absolutely atypical in girls with Turner syndrome.

BACKGROUND: It is unknown whether phenotypic expression of Hashimoto's thyroiditis (HT) might be conditioned by the association with Turner syndrome (TS). OBJECTIVES: To focus on the most recent pediatric studies concerning epidemiology and biochemical course of HT in TS girls. DESIGN: The epidemiological peculiarities of TS-related HT in pediatric age were compared with those usually observed in non-TS girls with HT and results are summarized in Tables 1 and 2. CONCLUSIONS: 1) phenotypical expression of HT in TS girls is significantly different from that observed in girls without TS; 2) such differences concern the epidemiological picture, the biochemical presentation modes and also the natural history from HT diagnosis onwards; 3) these peculiarities of TS-related HT are not necessarily linked with a specific karyotype.
