The aim of this study was to demonstrate the efficacy of methylprednisolone, as a single 40-mg dose, injected into the masseter muscle upon completion of extraction of impacted lower third molars. A prospective, randomized cross-over study was made of 35 healthy patients. The difficulty of extraction was similar in all cases. The study group received 40 mg of methylprednisolone injected into the masseter muscle via the intrabuccal approach, immediately after suturing of the surgical wound. The control group received no intramuscular corticoid. Evaluations were made of postoperative pain, trismus and swelling. Oral aperture was measured, along with the following distances for the assessment of swelling: tragus-lip commissure, gonion-lip commissure and gonion-external canthus of the eye, before and 2 and 7 days after surgery. The patients administered methylprednisolone showed superior results after surgery in terms of oral aperture, pain and all the facial swelling parameters, with statistically significant differences versus the controls (p

Impacted third molar extraction causes considerable swelling in the days immediately following surgery. The aim of the present investigation was to evaluate the efficacy of methylprednisolone as a single 40-mg intramuscular dose in controlling the complications of impacted lower third molar surgical removal. Thirty-five patients were evaluated within the framework of a consecutive sampling and double-blind study with intrasubject measurements. Extraction comprised ostectomy with tooth sectioning of both lower third molars under local anesthesia. The study group received 40 mg of methylprednisolone injected into the gluteal region, while the controls received no such medication. In each individual one molar was randomly assigned to the study group and the other to the control series – with extraction of the two teeth being spaced 1 month apart. Evaluations were made of postoperative pain, trismus and swelling, and measurements were obtained for oral aperture and various distances (tragus-lip commissure, gonion-lip commissure and gonion-external canthus of the eye) before surgery and 2–7 days after extraction. Statistical correlations were made based on the Student t-test for the comparison of means of related samples. A statistically and clinically significant association was observed 2 days after surgery between methylprednisolone administration and increased oral aperture and diminished facial swelling. Likewise, less pain was recorded in the study group 6 h after surgery. The results confirm the efficacy of methylprednisolone in providing a more comfortable postoperative course after surgical extraction of impacted lower third molars.

Urinary excretion of 11-deoxy-17-ketosteroids was studied in 20 to 22 women with normal menstrual cycles on the 7, 10, 14 and 20th days of their cycles. The fraction studied showed a significant cyclic variation with a type of pattern for Androsterone and Aetiocholanolone and another one for the Dehydroepiandrosterone. The possibity of one metabolic path for the former metabolites and a different one for the latter, plus its close conection with the functional changes of the ovary, were arrived at.
