Rotator cuff injuries and factors associated with reoperation.

Objective: To evaluate the prevalence of rotator cuff tears and describe the profile of reoperated patients, causes of repeated tendon tears, tear evolution and range of times between surgical procedures.

Method: This was a cross-sectional study involving 604 surgical procedures performed at two regional referral hospitals between January 2006 and December 2012. After approval by the ethics committee, data describing the patients' epidemiological profile were gathered at a single time, using Cofield's classification to measure the extent of the tears, all of which underwent arthroscopic surgery.

Evaluation of the results from arthroscopic tenodesis of the long head of the biceps brachii on the tendon of the subscapularis muscle.

Objectives: The aim of this study was to evaluate the results from arthroscopic tenodesis of the long head of the biceps brachii (LHBB) on the tendon of the subscapularis muscle, with regard to the presence of pain, subscapularis lesion, presence of Popeye's sign and patient satisfaction.

Methods: A prospective cohort study was conducted on 32 patients with LHBB lesions, through preoperative interviews and physical examinations, which were repeated six months after the operation. The main variables studied were the belly press, bear hug and lift-off tests, Popeye's sign, anterior pain and satisfaction.

Effect of methylprednisolone use on the rotator cuff in rats: biomechanical and histological study.

Objective: To evaluate the influence of treatment with different doses of methylprednisolone on the mechanical resistance and possible histological alterations of the rotator cuff tendon in rats.

Methods: Male Wistar rats were divided randomly into four treatment groups: sham, vehicle or 0.6 mg/kg or 6.

Locus of pain control associated with medication adherence behaviors among patients after an orthopedic procedure.

Background: Locus of pain control (LPC) is characterized by the behavior of people coping with their health problems, as a result of their own actions (internal control) or external factors or other people (external control). This parameter can be associated with medication adherence, in addition to other psychosocial factors that may also influence this behavior. This study was performed to investigate the influence of the LPC on medication adherence in patients undergoing an orthopedic procedure.

[Factors associated with the understanding of medical prescriptions in the Unified Health System in a city in Southern Brazil].

A cross-sectional study via interviews was conducted in the city of Tubarão in the state of Santa Catarina in order to identify the association between prescription indicators and the profile of the healthcare users and their understanding of medical prescriptions among patients attended by the Unified Health System. Information was collected on the profile of the healthcare users, the prescription indicators recommended by the World Health Organization and the understanding of drug prescriptions. Three hundred subjects were interviewed and the associated factors were identified using the Chi-square test.
