Contact dermatitis is a highly prevalent disease in the health care area, being the second most frequent consult in dermatology. This article will make a complete review of the subject, starting with its definition and the different types of dermatitis described with their main characteristics; it will describe the etiology and pathogenesis, the main risk factors related with the health care workers that influence in the evolution of the disease. It also will mention the principal clinical manifestations and how they evolve during time. Concluding, the physician should perform a complete medical history with emphasis on the anamnesis and physical examination of the skin and lesions, for an appropriate medical correlation to guide the diagnosis and define which one is the most appropriate laboratory test, in order to choose the ideal treatment. As contact dermatitis is a recurrent disease, education is fundamental to create conscious in the patient about his condition, and prevent future relapses. It is physician's responsibility to make a strict follow-up, in order to avoid disease progression and improve its outcome. [ABSTRACT FROM AUTHOR]

Objective: To determine if sonotherapy reduces the anxiety level and postoperative pain in adults undergoing outpatient orthopedic surgery under regional anesthesia., Method: A randomized, double-blind, placebo-controlled study in 80 adult patients undergoing orthopedic surgery, 40 received intervention with sonotherapy and 40 did not receive it. Pain, anxiety in the preoperative period, immediate postoperative, high, 24 and 48 hours later were measured. Hemodynamic parameters were measured in four moments., Results: No significant differences were found between the two groups in the pain scales neither anxiety. A significant reduction of the systolic blood pressure was observed after the application of sonotherapy and in recovery. There was no difference in other hemodynamic variables such as heart rate, respiratory rate, arterial oxygen saturation or diastolic blood pressure between groups, however, the observed changes in some of them occurred faster in the intervention group., Conclusions: In adult patients undergoing outpatient orthopaedic surgery under regional anaesthesia, sound therapy is a novel strategy that significantly reduces systolic blood pressure, considered as an indicator of decreased anxiety. However, in our study, no difference could be demonstrated in terms of pain control or the need for additional sedation or analgesia., (Copyright: © 2019 Permanyer.)
