[Unusual presentation of juvenile idiopathic arthritis and autoimmune hepatitis].

The coexistence of autoimmune hepatitis and juvenile idiopathic arthritis is very rare. This is the case of an 18 month old female patient whose first sign of disease was torticollis due to an underlying atlanto-axial subluxation. Three months later, bilateral knee arthritis developed and she was diagnosed with Juvenile Idiopathic Arthritis.

[Surgical stress and hypophyseal-adrenal activation in childhood].

Introduction: The study on the physiological alterations due to surgical aggression (surgical stress), widely investigated in adults, is less known in paediatric age.

The Objective: Of this work is to quantify surgical stress (evaluated by means of Oxford Scale as high or low depending on its value bigger or lower than 6), after determining changes of plasmatic concentrations of ACTH, beta-endorphin and cortisol in operated children.

Patients And Methods: Observational analytic design of a prospective cohort with internal comparison of the groups.

Hormonal response to surgical stress in schoolchildren.

Purpose: To determine hormone concentrations (ACTH, cortisol, beta-endorphin) in children before and after surgery, to assess the correlation between any hormonal changes and to study the influence exercised on them by the severity of surgical stress and the elective/emergency nature of the surgery.

Patients And Methods: Prospective cohort of 78 children (age= 10+/-2.6 years, range 6-13 years) undergoing elective or emergency surgery.

[Hormonal response and two special techniques of postoperative analgesia in pediatric surgery].

Aims: We studied neuroendocrine response in the postoperative pain relief in pediatric patients treated with two analgesic techniques (conventional intravenous analgesia and patient controlled analgesia).

Material And Methods: A double blind study was made in 30 patients, 6-14 year-old children, under total intravenous anesthesia for programmed surgery. An intravenous analgesia dose of 0.
