Background The benefit of myocardial perfusion imaging (MPI) over exercise ECG stress testing alone is unclear in individuals attaining a workload of ≥10 METS. The purpose of this prospective study is to determine mortality and nonfatal cardiac events in patients at either intermediate pretest risk for CAD or patients with known CAD, achieving ≥10 METS regardless of peak exercise heart rate. The authors previously reported a low prevalence of significant ischemia in this patient cohort. Methods Baseline characteristics, ECG stress test findings, and perfusion and function results from quantitative gated 99mTc-SPECT MPI were compared by achievement of a maximum age-predicted heart rate ≥85% in 509 consecutive patients who reached ≥10 METS. Events including all-cause and cardiac mortality, non-fatal myocardial infarction (MI), and late revascularization (>4 weeks after MPI) were prospectively collected. Results Of the 509 patients achieving ≥10 METS, follow-up for mortality was obtained in 463 (91%). Those lost to follow-up were older and had higher rates of tobacco use. The prevalences of CAD risk factors, prior known CAD, and MPI abnormalities were higher for the 68 patients failing to reach 85% of their target heart rate. The rate of ≥10% left-ventricular (LV) ischemia by MPI remained very low irrespective of attained heart rate (0.6% (3/463)). Six (1.2%) had an LVEF < 40%. Death occurred in 12 (2.6%) patients, one of which was classified as cardiac (0.1%/year). The other 11 deaths were related to cancer. Additionally, there were three nonfatal MIs (0.7 %) and one late revascularization (0.2%). Only one of these patients had any ischemia on MPI. No cardiac event patient had exercise ST depression or ≥5% LV ischemia. Conclusions Thus, patients at intermediate risk for CAD or known CAD achieving ≥10 METS have a very low prevalence of ≥10% LV ischemia and very low rates of cardiac mortality, nonfatal MI, and late revascularization, irrespective of heart rate achieved. Cardiac events did not correlate with abnormalities on the index MPI study. These results suggest that patients who attain ≥10 METS during exercise stress have an excellent prognosis over an intermediate term of follow-up, regardless of peak exercise heart rate achieved. The added value of MPI to standard exercise ECG testing in this population is questionable.

Background Open trigger finger release is generally considered a simple low-risk procedure. Reported complication rates vary widely from 1 to 43 %, mostly based on small studies. Our goal was to determine the incidence of complications in a large consecutive series, while also identifying potential risk factors. Methods All open trigger finger releases performed from 2006 to 2009 by four fellowship-trained hand surgeons at a single institution were retrospectively reviewed. There were 795 digits released in 543 patients. Complications were defined as signs or symptoms requiring further treatment and/or considered unresolved by 1 month postoperatively. Complications requiring operative intervention were regarded as major. Multivariable analysis was performed to determine possible risk factors for complications. Results There were 95 documented complications among 795 digits (12 %). The most common complications involved persistent pain, stiffness, or swelling, persistent or recurrent triggering, or superficial infection. Most were treated nonoperatively with observation, therapy, steroid injection, or oral antibiotics. There were 19 reoperations (2.4 %), mostly including revision release, tenosynovectomy, and irrigation and debridement. Male gender, sedation, and general anesthesia were independently associated with complications, while age, diabetes, hypothyroidism, recent injection, and concurrent procedures were not associated.Conclusions Open trigger finger release is generally a lowrisk procedure, although there is potential for complications, some requiring reoperation. Male gender, sedation, and general anesthesia may be associated with greater risk. Surgeons should be careful to thoroughly discuss the risk of both major and minor complications when counseling patients.

» Surfing is safe: the risk of injury ranges from 0.26 to 0.90 injuries per surfer per year, 0.06 to 3.5 injuries per 1,000 days of surfing, and 1.1 to 13.0 injuries per 1,000 hours of surfing.» The most common acute surfing injuries are lacerations, contusions, and sprains; the head and the neck as well as the lower extremities are the locations that are affected most.» The most common mechanism of injury is striking a surfer’s own board or that of another surfer.» A pathology that is unique to surfers is surfer’s myelopathy; bites and/or stings by sea life and infections caused by marine life also occur in surfers.
