Background: Active rehabilitation has an important role in the management of patellofemoral pain syndrome (PFPS). Although some studies have shown the benefit of hip-muscle strengthening, the effect of combining hip-muscle stretching with strengthening has not yet been defined. Purpose: To evaluate the effect of combined strengthening of the hip external rotators and abductors and stretching of the hip internal rotators on pain and function in patients with PFPS. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: A total of 109 patients with PFPS (75 female and 34 male; mean age, 31.6 ± 10.8 years) were first randomly assigned to protocol A (n = 67) of the A-B arm (AB group; standard rehabilitation) or protocol B (n = 42) of the B-A arm (BA group; standard rehabilitation with strengthening of the hip external rotators and abductors and stretching of the hip internal rotators). Each protocol consisted of 3 sessions a week for 4 weeks. After a washout period, corresponding to a symptom-free period, rehabilitation programs were crossed over. A visual analog scale (VAS) evaluating perceived pain, the Functional Index Questionnaire (FIQ), and the Kujala score were administered at baseline, the end of each rehabilitation protocol, and 12 weeks after the completion of the second protocol for each group. Results: Until the final follow-up, VAS, FIQ, and Kujala scores were significantly improved in both the A-B and B-A arms ( P < .05 for all). Compared with protocol A, protocol B provided significant improvement in terms of pain and function in both the BA (VAS and Kujala; P < .001) and AB (VAS and Kujala; P < .001) groups. Conclusion: Combined strengthening of the hip abductors and external rotators with stretching of the hip internal rotators provided better outcomes, which were maintained for at least 12 weeks, in terms of pain and function in patients with PFPS.

The meeting of the Working Group on standard stars (WG-SS) opened under the chairmanship of Corbally. Gray, as editor, gave a report on the Standard Stars Newsletter (SSN). Through a round of thanks given to Gray, it was recognized by the two dozen present that this publication is the major vehicle between WG-SS meetings for achieving its tasks, namely promoting and communicating work on standard stars.

Abstract In this study, 42 Wistar albino female rats (n = 42, 8 weeks old) were used. Rats were divided into 6 groups and 7 rats included each group. Groups: (i) Control Group: Standard diet; (ii) RJ (royal jelly) Group: Standard diet + royal jelly; (iii) F50 Group: Standard diet + 50 mg/kg fluoride; (iv): F100 Group: Standard diet + 100 mg/kg fluoride; (v) F50 + RJ Group: Standard diet + 50 mg/kg fluoride + royal jelly; (iv): F100 + RJ Group: Standard diet + 100 mg/kg fluoride + royal jelly. After the 8-week study period, the rats were decapitated and their muscle tissues were removed. Expression levels of Caspase-3, Caspase-6, Bax, Tnf-α, IL1-α and Bcl-2 proteins in muscle tissue were determined by Western Blotting method. Histopathological analyzes were also performed on the muscle tissue. MDA, GSH, and CAT analyzes were determined by spectrophotometric analysis. According to our findings, Bcl-2, Tnf-α and IL1-α protein expression were increased in damage groups compared to control and royal jelly groups, Caspase-3, Caspase-6 and Bax protein expression levels decreased in damage groups. There was an increase in MDA level in damage groups compared to the control and royal jelly groups, CAT and GSH levels decreased in damage groups. According to histopathological analysis results, edema and inflammatory cell formations were found in the injury groups, a tendency to decrease in these injuries was observed in the treatment groups. Based on these results, we can say that royal jelly has protective effects against fluoride damage.
