We report the detection of high-amplitude X-ray flaring of the AGN HE 1136-2304, which is accompanied by a strong increase in the flux of the broad Balmer lines, changing its Seyfert type from almost type 2 in 1993 down to 1.5 in 2014. HE 1136-2304 was detected by the XMM-Newton slew survey at >10 times the flux it had in the ROSAT all-sky survey, and confirmed with Swift follow-up after increasing in X-ray flux by a factor of ~30. Optical spectroscopy with SALT shows that the AGN has changed from a Seyfert 1.95 to a Seyfert 1.5 galaxy, with greatly increased broad line emission and an increase in blue continuum AGN flux by a factor of >4. The X-ray spectra from XMM-Newton and NuSTAR reveal moderate intrinsic absorption and a high energy cutoff at ~100 keV. We consider several different physical scenarios for a flare, such as changes in obscuring material, tidal disruption events, and an increase in the accretion rate. We find that the most likely cause of the increased flux is an increase in the accretion rate, although it could also be due to a change in obscuration. [ABSTRACT FROM AUTHOR]

A surgical procedure for the successful repair of the temporomandibular joint meniscus is described. Twenty-three patients have been treated by this procedure, with both objective and subjective improvement. The procedure is accomplished with minimal technical difficulty and minimal cosmetic defect.

Patients with skeletal Class II malocclusions and deep bites can be difficult to manage properly. Dental compensations, mandibular retrognathia, vertical dysplasia of inadequate posterior alveolar growth, and compensating chin effects must be considered if one is to achieve ideal treatment results. The eleven cases presented were managed through a combination of surgery, orthodontics, and rapid extrusion of the posterior dental arches. The rapid extrusion process is begun during the surgical healing phase, thereby decreasing total treatment time. Other advantages include simplicity of the surgical procedure, acceptance by the patient, stability of the facial and dental results, and possible avoidance of additional chin surgery.
