Erectile dysfunction in obstructive sleep apnea patients: A randomized trial on the effects of Continuous Positive Airway Pressure (CPAP).

Objectives: Obstructive sleep apnea (OSA) is among the least studied risk factors for erectile dysfunction (ED). We aimed to determine ED prevalence in newly-diagnosed OSA patients, describe their main characteristics and assess continuous positive airway pressure (CPAP) effects on ED.

Methods: Cross-sectional study assessing ED prevalence in OSA patients and open-label, parallel, prospective randomized controlled trial evaluating 3-month CPAP treatment effects on sexual function, satisfaction, and psychological, hormonal and biochemical profiles.

Prepubertal testicular tumours and efficacy of testicular preserving surgery.

Study Type: Therapy (case series).

Level Of Evidence: 4. What's known on the subject? and What does the study add? Testicular tumours in childhood are very rare.

[Early ultrasound detection of renal tumors in patients with end stage renal disease in dialysis].

Objectives: Patients with end stage renal disease in dialysis are a population susceptible to suffer various types of cancers, mainly in the kidney and urinary tract. These tissues suffer systemic carcinogenic effects, including all that result from chemical and immunological changes secondary to renal failure, from the treatment they receive and dialysis itself. In the present article we determine the clinical, epidemiological, and pathological characteristics of patients with chronic renal failure in dialysis who presented renal tumors during the evolution of their disease over the last ten years.
