Findings regarding the association of cohort changeovers with patient outcomes are mixed. We sought to examine the association of resident and fellow changeovers with a comprehensive set of indicators. We performed a cross-sectional comparative study including all French teaching and non-teaching hospitals. All-cause mortality and length of stay were assessed. Focused analysis for three medical conditions (myocardial infarction, intestinal hemorrhage, stroke) and three surgical procedures (colorectal, vascular and spine surgery) was performed regarding other quality and efficiency indicators (readmissions, intensive care unit admission, transfers)...

William Edward Gallie (1882-1959) was a Canadian general surgeon with special expertise in orthopedic surgery. His experience with surgical management of cervical spine subluxation led him to invent a method of cervical wiring of the atlas to the axis. His method of C1-2 wiring has since been modified, but it still remains one of the three most commonly taught wiring techniques in neurosurgical training programs. Gallie is also hailed for instituting the first surgical training program in Canada, a curriculum his pupils memorialized as the "Gallie course" in surgery...

Giant cell tumor (GCT) is a benign, locally aggressive tumor that rarely occurs in the spine. They usually occur in patients between 20 and 40 years of age; some patients with GCT present in hospital with pregnancy. The management of these patients can be challenging. The current study reports a case of GCT located in the sixth thoracic vertebra of a 31-year-old female at 34 weeks of gestation. An osteolytic lesion, 3.5 cm × 3.5 cm in diameter, was identified on CT. An MRI test of the lesion revealed a soft tissue mass involving the T 6-7 vertebrae, extending to the right pedicle of the T 6 vertebra and causing significant spinal cord compression...

Mild primary hyperparathyroidism (PHPT) is known to affect the skeleton, even though patients usually are asymptomatic. Treatment strategies have been widely discussed. However, long-term randomized studies comparing parathyroidectomy to observation are lacking. The objective was to study the effect of parathyroidectomy (PTX) compared to observation (OBS) on bone mineral density (BMD) in g/cm(2) and T-scores, and on biochemical markers of bone turnover (P1NP and CTX-1), in a prospective randomized controlled study of patients with mild PHPT after 5 years of follow-up...

Graft infection following aortic aneurysms repair is an uncommon but devastating complication; its incidence ranges from <1% to 6% (mean 4%), with an associated perioperative and overall mortality of 12% and 17.5-20%, respectively. The most common causative organisms are Staphylococcus aureus and Escherichia coli; causative bacteria typically arise from the skin or gastrointestinal tract. The pathogenetic mechanisms of aortic graft infections are mainly breaks in sterile technique during its implantation, superinfection during bacteremia from a variety of sources, severe intraperitoneal or retroperitoneal inflammation, inoculation of bacteria during postoperative percutaneous interventions to manage various types of endoleaks, and external injury of the vascular graft...

BACKGROUND: The vast majority of studies emphasize the greater morbidity/mortality for elective spine surgery in morbidly obese patients. METHODS: This review focuses on the increased morbidity/mortality of performing elective spinal operations in morbidly obese patients. There are two definitions of morbid obesity; a body mass index (BMI) of equal to or greater than 35 plus two major comorbid factors (e.g., hypertension, diabetes, etc.) or a BMI (morbidly obese III) of =≥40 kg/m(2)...

Nancy E Epstein
BACKGROUND: Minimally invasive surgery (MIS) spine procedures were developed to limit operative time, the extent of dissection, and reduce perioperative morbidity. Here, we asked what are the "learning curves" for these MIS spine procedures? METHODS: We reviewed studies in the literature that discussed the "learning curves" attributed to performing different MIS spine surgical procedures. Of interest, the majority were single-surgeon series. RESULTS: Very few articles assessed the learning curves for different MIS spine procedures...

The current case report describes two cases of alkaptonuric ochronosis for anesthetic management. Alkaptonuria is a rare genetic orphan disease of tyrosine metabolism characterized by an accumulation of homogentisic acid in cartilage and connective tissues. Patients present most commonly for orthopedic joint surgery due to progressive arthropathy that can be misdiagnosed many a times. However respiratory, airway, cardiovascular and genitourinary systems complications can occur with age progressing. Restricted range of motion of cervical spine may lead to difficulty with airway management...
