Intra-abdominal hematomas and identifiable risk factors in patients receiving subcutaneous enoxaparin.

Background: Low molecular weight heparin has proven to be safe and effective but is not without potential risks such as spontaneous bleeding in the abdominal cavity. There is limited evidence evaluating the true incidence of this potential risk and the available literature is primarily via case reports.

Case Summary: The purpose of this study was to identify the incidence and risk factors associated with enoxaparin use (prophylaxis or treatment) abdominal hematomas in a 350-bed community hospital during an 8-month time period.

Accidental Hypothermia Associated with Intracardiac Thrombi.

Accidental hypothermia and thrombosis are rarely associated and encountered. A 66-year-old male and 62-year-old male were both admitted with accidental hypothermia. Patient 1 had a rectal temperature of 28.

Tetralogy of Fallot with pheochromocytoma: an unusual therapeutic challenge.

An adult with unoperated tetralogy of Fallot diagnosed simultaneously with pheochromocytoma is extremely rare. This poses obvious diagnostic and therapeutic challenges. A 29-year-old woman with these conditions was successfully operated on for both diseases in the same hospitalization.

Impact of appropriate use on the prognostic value of single-photon emission computed tomography myocardial perfusion imaging.

Background: Appropriate use criteria (AUC) have been developed to aid in the optimal use of single-photon emission computed tomography (SPECT)-myocardial perfusion imaging (MPI), a technique that is a mainstay of risk assessment for ischemic heart disease. The impact of appropriate use on the prognostic value of SPECT-MPI is unknown.

Methods And Results: A prospective cohort study of 1511 consecutive patients undergoing outpatient, community-based SPECT-MPI was conducted.

The prognostic value of transient ischemic dilatation with otherwise normal SPECT myocardial perfusion imaging: a cautionary note in patients with diabetes and coronary artery disease.

Background: The prognostic implications of transient ischemic dilatation (TID) of the left ventricle with otherwise normal single-photon emission computed tomography myocardial perfusion imaging (MPI) remain controversial. Whether this finding may have prognostic implications only in high-risk populations, such as patients with diabetes or manifest coronary artery disease (CAD), is uncertain.

Methods: We conducted a prospective cohort study of 1,236 consecutive patients with normal (99m)Tc-sestamibi MPI, defined as normal perfusion (summed stress score = 0) and normal left ventricle volume and function.

The prognostic value of cardiac SPECT performed at the primary care physician's office.

Background: The prognostic value of single-photon emission computed-tomography (SPECT)-myocardial perfusion imaging (MPI) is well documented. However, the utility of SPECT-MPI when performed at a low-volume primary care physician's (PCP's) office is unknown.

Methods: We conducted a prospective cohort study of consecutive patients referred by their PCP to undergo a stress-MPI at the PCP's office using a mobile laboratory.
