The role of immediate stress testing in low-risk patients with a potential acute coronary syndrome has not been rigorously evaluated with respect to impact on 30-day cardiovascular events. We evaluated the impact of inpatient, outpatient, or no stress testing (ETT) on 30-day cardiovascular outcomes. We performed a prospective cohort study in which consecutive patients with chest pain were admitted to a non-intensive-care telemetry bed over 16 months. ⋯ The cardiovascular outcomes (with 95% confidence interval) for patients with inpatient ETT versus outpatient ETT versus no ETT were as follows: death, 0% (0-1.5%) vs 0% (0-4.1%) vs 1% (0.3-1.7%); AMI, 1% (0.1-2.4%) vs 1.4% (0.1-4.1%) vs 0.3% (0.1-0.7%); PCI, 0.5% (0.1-1.5%) vs 1.3% (0.1-4.1%) vs 0% (0-0.4%); and CABG, 0.5% (0.1-1.5%) vs 0% (0-4.1%) vs 0.2% (0.1-0.4%). There was no statistical difference in 30-day cardiovascular outcomes among patients who received inpatient, outpatient, or no ETT within 30 days. This suggests that patients with chest pain who are admitted to non-intensive-care telemetry (or observation unit) beds might not need stress testing before hospital release.

Spontaneous hemopneumothorax is a rare clinical entity. A large spontaneous hemopneumothorax is life-threatening, and mortality increases with delayed recognition and intervention. The initial chest radiography and the amount of blood drained from the inserted chest tube frequently underestimates the actual blood loss from the active bleeder around the ruptured apical bullae, leading to failed recognition of a potentially life-threatening condition until unexpected hemodynamic collapse develops. We report 2 cases of spontaneous hemopneumothorax to emphasize the importance of early recognition and prompt surgical intervention by video-assisted thoracoscopic surgery (VATS).

Delayed treatment of ethylene glycol or methanol poisoning can result in life-threatening complications, but obtaining quantitative levels is delayed by several hours in most hospitals. Calculating the anion gap and the osmol gap are recommended to hasten identification and treatment in cases of suspected toxic alcohol poisoning. ⋯ Our "Mountain" schematic illustrates the presence of an elevated osmol gap found early in toxic alcohol poisoning and the presence of an elevated anion gap found later in the course of poisoning. Using the "Mountain" diagram as a clarification of the temporal relationship between the anion and the osmol gap can improve the diagnostic use of these screening assays.

The aim of this study was to determine whether there is a relationship between climatic factors and suicidal behavior. A total of 1,119 suicide attempts were collected from hospital records between 1996 and 2001. A clear seasonal variation was seen in suicide attempts in the 15-24, 25-34, and over 65 age groups in men and in the 15-24, 25-34, and 35-44 age groups in women with peaks in the spring and summer. ⋯ People attempting suicide who have depression, anxiety, or a psychotic disorder usually attempt suicide in the summer. Whereas the monthly averages of humidity, ambient temperature, duration and intensity of sunlight were positively correlated with the number of monthly suicide attempts, cloudiness and atmospheric pressure were negatively correlated. In conclusion, we must keep in mind that suicides and suicide attempts are not only the effect of climatic changes and that the most important component is the individual's ability to deal with conflicts.

Missed diagnosis of avascular necrosis (AVN) may result in substantial morbidity. Early diagnosis is crucial for appropriate intervention and, ultimately, improved outcome. ⋯ Avascular necrosis (AVN) of the bone can occur when the blood supply to the bone is disrupted and is usually found in areas with terminal circulation. Commonly involved bones include the femoral head, talus, and scaphoid.
