Consensus guide on prophylactic gonadectomy in different sex development.

The risk of suffering from gonadal germ cell tumors (GCT) is increased in some patients with different sexual development (DSD), mainly in those with Y chromosome material. This risk, however, varies considerably depending on a multitude of factors that make the decision for prophylactic gonadectomy extremely difficult. In order to make informed recommendations on the convenience of this procedure in cases where there is potential for malignancy, this consensus guide evaluates the latest clinical evidence, which is generally low, and updates the existing knowledge in this field.

[Management guidelines for disorders / different sex development (DSD)]. / Guía de actuación en las anomalías de la diferenciación sexual (ADS) / desarrollo sexual diferente (DSD).

Disorders of Sex Development (DSD) include a wide range of anomalies among the chromosomal, gonadal, and phenotypic (genital) characteristics that define sexual differentiation. At present, a definition as Different Sexual Development (DSD) is currently preferred. They originate in the pre-natal stage, are classified according to the sex chromosomes present in the karyotype. The known genetic causes are numerous and heterogeneous, although, in some cases, they may be secondary to maternal factors and/or exposure to endocrine-disrupting chemicals (EDCs). The diagnosis and treatment of DSD always requires multidisciplinary medical and psychosocial care. An aetiological diagnosis needs the interaction of clinical, biochemical (hormonal), genetic, imaging and, sometimes, surgical examinations. The treatment should deal with sex assignment, the possible need for hormone replacement therapy (adrenal if adrenal function is impaired, and with sex steroids from pubertal age if gonadal function is impaired), as well as the need for surgery on genital structures (currently deferred when possible) and/or on gonads (depending on the risk of malignancy), the need of psychosocial support and, finally, an adequate organisation of the transition to adult medical specialties. Patient Support Groups have a fundamental role in the support of families, as well as the interaction with professional and social media. The use of Registries and the collaboration between professionals in Working Groups of national and international medical societies are crucial for improving the diagnostic and therapeutic tools required for the care of patients with DSD.

Initial Approach to Childhood Obesity in Spain. A Multisociety Expert Panel Assessment.

PURPOSE: In recent years, the incidence of childhood obesity in Europe, and Spain in particular, has increased dramatically. Bariatric surgery could play a major role in treating of adolescents with severe obesity. However, no specific guidelines for bariatric surgery currently exist in Spain. METHODS: The Board of the Spanish Society for Obesity Surgery and Metabolic Diseases (SECO) proposed a study of childhood obesity by using the Delphi method. This prospective study involved 60 experts from nine national societies. Each society leader recruited experts from their society in obesity-related fields. Two online questionnaires were taken, and consensus on guidelines for various obesity treatments was reached according to the percentage of answers in favor or against inclusion of a given guideline. Based on these results, preoperative, surgical management and follow-up of childhood obesity management among others were analyzed. RESULTS: The survey results indicated significant concern among all societies regarding obesity. There was strong consensus with regard to adolescents and obesity, medical treatment, dietary recommendations, environmental and social factors, and goals for adolescents with obesity. Consensus on the use of intragastric balloons and other techniques was not reached. However, biliopancreatic diversion was rejected as a primary treatment, and mandatory psychological/psychiatric assessment was agreed upon. Inclusion criteria accepted were similar to those for adults with the exception of surgery in those with a body mass index <40. CONCLUSIONS: Spanish obesity-related societies are aware of the societal problem of childhood obesity. Multisociety development of national approaches may arise from consensus-building studies among specialists.
