Nonepileptic seizures in individuals attending neurological services in New Zealand.

Objectives: This study examined the demographic, social, and clinical (neurological and psychiatric) characteristics of people with psychogenic nonepileptic seizures (PNES) presenting to tertiary neurological services at Auckland District Health Board, New Zealand.

Methods: Electronic notes and video-electroencephalography (video-EEG) data gathered from the telemetry unit based on synchronized acquisition (motor activity and brain electrophysiology) over a five-year period (2011 to 2015 inclusive) were retrospectively examined. Two groups were compared: people with PNES only or people with combined PNES and epileptic seizures (ES) (the group with PNES) and a control group with ES only, matched 1:1 by age and gender.

Migration of Kirschner wires into the mediastinum after stabilization of sterno-clavicular lesions. A report of two cases.

The authors describe two cases of intrathoracic migration of Kirschner wires used for fixation of unstable Allman grade III sternoclavicular dislocation. The wires continue their migration after 10 years despite the risk and the need to treat such complications.

An experimental study of the redistribution of patellofemoral pressures by the anterior displacement of the anterior tuberosity of the tibia.

Using a series of miniature piezoelectric transducers constructed by the authors, a study was made of the effect of anterior displacement of the tuberosity of the tibia on the distribution of pressures in the patellofemoral joint. Proportionally, the most efficient displacements are those set at 1 cm; after this, and as advancement of the tuberosity is increased, the overall pressure continues to decrease progressively (although more slowly) because there are zones that, according to their situation, receive increased instead of decreased pressures. Consequently, values even higher than those of the original situation are reached.

[Reconstructive surgery using a massive prosthesis in loosening of a hip prosthesis].

Thirteen cases with loosening of THR treated by a massive prosthesis are reviewed. In previous years, with more conservative surgery, the loss of bone stock was most important. The results after a long follow-up were satisfactory.

Sternoclavicular dislocation. Treatment and complications.

Based on Allman's classification, the authors conducted a critical study on the results of treatment of 17 sternoclavicular dislocations, 14 anterior and 3 posterior. They propose conservative treatment for subluxations and operative treatment for total dislocations, particularly when posterior. Tomography was required for precise diagnosis.
