Idiopathic musculoskeletal pain, musculoskeletal pain syndromes, and use of electronic devices in adolescents with asthma.

Objective: To evaluate idiopathic musculoskeletal pain, musculoskeletal pain syndromes, and use of electronic devices in adolescents with asthma and healthy controls.

Methods: Cross-sectional study was conducted on 150 asthmatic adolescents and 300 controls. Adolescents completed a self-administered questionnaire regarding painful symptoms, use of electronic devices, and physical activity.

Adrenal steroidogenesis and ovarian reserve in adult childhood-onset systemic lupus erytematosus patients.

Objective: To assess overall adrenal mineralocorticoid/glucocorticoid/androgen steroidogenesis in childhood-onset systemic lupus erythematosus (cSLE) patients and the possible effect of prednisone on adrenal hormones and ovarian reserve.

Methods: Fifty-one adult cSLE (ACR criteria) patients and 23 healthy controls were evaluated for adrenal steroidogenesis including mineralocorticoid (progesterone, deoxycorticosterone, aldosterone), glucocorticoid (17-OHprogesterone, 11-desoxycortisol, cortisol), and androgen (dehydroepiandrosterone-sulfate, androstenedione, total testosterone, and dihydrotestosterone) hormones. Ovarian reserve assessment included follicle-stimulating hormone (FSH), estradiol, anti-Müllerian hormone, ovarian volumes, and antral follicle count.

Sexual function in female juvenile idiopathic arthritis patients.

Objective: To evaluate sexual function female adolescents and young adults with juvenile idiopathic arthritis (JIA) and healthy controls.

Methods: After exclusion, 21 female adolescent and young JIA patients and 25 healthy controls were selected for this study. Sexual function was assessed by the Sexual Quotient Questionnaire for Females (SQQ-F) score, which is a validated tool and adapted for Brazilian Portuguese language.

Musculoskeletal pain and musculoskeletal syndromes in adolescents are related to electronic devices.

Objective: To evaluate television and simultaneous electronic devices use in adolescents with musculoskeletal pain and musculoskeletal pain syndromes.

Methods: A cross-sectional study was performed in 299 healthy adolescents of a private school. All students completed a self-administered questionnaire, including: demographic data, physical activities, musculoskeletal pain symptoms, and use of simultaneous television/electronic devices (computer, internet, electronic games, and cell phones).

Alcohol, smoking and illicit drug use in pediatric systemic lupus erythematosus patients.

Objective: To evaluate alcohol, smoking and/or illicit drug use, and history of bullying in adolescent childhood-onset systemic lupus erythematosus and healthy controls.

Methods: 174 adolescents with pediatric rheumatic diseases were selected. All of the 34 childhood-onset systemic lupus erythematosus patients and 35 healthy controls participated in this study.

[Optic neuritis in juvenile idiopathic arthritis patient].

Optic neuritis (ON) was rarely reported in juvenile idiopathic arthritis (JIA) patients, particularly in those under anti-tumor necrosis factor alpha blockage. However, to our knowledge, the prevalence of ON in JIA population has not been studied. Therefore, 5,793 patients were followed up at our University Hospital and 630 (11%) had JIA.
