[Effects of glycine on auditory evoked potentials among diabetic patients with auditory pathway neuropathy].

Background: Glycine inhibits the formation of advanced glycation end products that may cause central and peripheral neuronal damage, affecting also the auditory nerve.

Aim: To evaluate the effect of glycine on auditory nerve conduction and hearing level among patients with type 2 diabetes mellitus and auditory neuropathy.

Material And Methods: Twenty grams of oral glycine per day were administered during 6 months to 28 type 2 diabetic patients aged 58 ± 6 years, with auditory pathway neuropathy.

[Evaluation with ultrasound and arthro-ultrasonography of complete rotator cuff rupture].

Introduction: Shoulder ultrasonography is revised in the evaluation of complete rotator cuff tears. Also another technique known as artro-ultrasonography, which consist of a 10 mL solution injection inside the articular capsule to observe its escape to the subacromial-subdeltoidea bursae which implicates rotator cuff tear. It is compared against multiple standards like surgery, magnetic resonance, arthrography and rehabilitation to include positive and negative cases.

[Cost-effectiveness of the treatment of acute and chronic rhinosinusitis at the IMSS].

Introduction: Rhinosinusitis is one of the more common diseases encountered in outpatient visits to health care. The objective of this study was to determine the most cost-effective antibiotic treatment for patients with acute (RSA) and chronic rhinosinusitis (RSC) that is available at the Mexican Institute of Social Security (IMSS).

Methods: Cost-effectiveness analysis of RSA and RSC treatment from an institutional perspective.
