An anatomic study of inferior glenohumeral recess portals: comparative anatomy at risk.

Purpose: The purpose of this study was to describe the musculotendinous relations and neurologic structures at risk during establishment of posterior portals for access to the inferior glenohumeral recess (IGHR).

Methods: Three 18-gauge spinal needles were used to establish 2 posteroinferior portals and 1 axillary pouch portal in 14 embalmed cadaveric shoulders, without joint distention and arthroscopic visualization. At dissection, musculotendinous structures traversed by the needles were recorded, and distances from the (1) axillary nerve (at the deltoid undersurface, quadrangular space, and capsule), (2) nerve to teres minor (at the inferior border of the teres minor muscle and at the capsule), and (3) suprascapular nerve were measured.

Transfer of segmentally split pectoralis major for the treatment of irreparable rupture of the subscapularis tendon.

Irreparable ruptures of the subscapularis tendon represent a difficult surgical problem. An accepted treatment has been to utilize the pectoralis major as a transfer, using the superior half of the tendon, which involves parts of both the sternal and clavicular heads of the muscle. We undertook an anatomic study to investigate the possibility of using a segmentally split pectoralis transfer of the sternal portion alone, which may provide a transfer with a vector more closely matching that of the functioning subscapularis muscle.

Correlation between gene expression and morphological alterations in baboon carotid after balloon dilatation injury.

Treatment for fibroproliferative restenosis after angioplasty and endovascular surgery is an unmet medical need. Rational therapy and drug design still lack the very basic knowledge about the underlying biological processes leading to pathological changes in the vessel wall. We have developed a primate model for vascular response to denudation-overstretch injury of baboon carotid artery.

[Anxiety disorders in private practice psychiatric out-patients: prevalence, comorbidity and burden (DELTA study)].

Few data are currently available on the prevalence and associated characteristics of anxiety disorders in psychiatric out-patients in France, in particular in the private health-care. However, this represents one of the principal systems of care for patients suffering from anxiety disorders, with a possible direct access and several types of treatments available (pharmacotherapy but also different kinds of psychotherapy). The aim of our study was to describe the prevalence of anxiety disorders in a large sample of patients consulting in the private sector, and in addition to study the comorbidity, the severity of the disorders, their consequences on quality of life and health care consumption.
