Assembling the Puzzle: Taking into Account Clinical Presentation and Predictive Scores.

Syncope is a common cause of emergency department visits. Physicians must scrutinize for life-threatening causes to avoid patient morbidity and mortality. Clinical decision rules are used to stratify risks and guide the course of action, including the need for further testing. This is the case of a 83-year-old man was brought to the emergency department after a 5-minute episode of sudden loss of consciousness. Vital signs showed hypotension and physical examination was unremarkable. Despite Wells score of 0, clinical suspicion for pulmonary embolism persisted, for which further testing was pursued. D-dimer was elevated at 13.77 mcg/mL and a chest computed tomography with angiography showed an extensive bilateral pulmonary embolism involving the distal right and left main pulmonary arteries. He was started on full-dose anticoagulation. This case exemplifies the need of high clinical suspicion along with the importance of applying predictive scores for diagnosing unusual causes of syncope.

Cannabinoid Hyperemesis Syndrome: A Paradoxical Cannabis Effect.

Despite well-established antiemetic properties of marijuana, there has been increasing evidence of a paradoxical effect in the gastrointestinal tract and central nervous system, given rise to a new and underrecognized clinical entity called the Cannabinoid Hyperemesis Syndrome. Reported cases in the medical literature have established a series of patients exhibiting a classical triad of symptoms: cyclic vomiting, chronic marijuana use, and compulsive bathing. We present a case of a 29-year-old man whose clinical presentation strongly correlates with cannabinoid hyperemesis syndrome. Despite a diagnosis of exclusion, this syndrome should be considered plausible in the setting of a patient with recurrent intractable vomiting and a strong history of cannabis use as presented in this case.

Cocaine induced vasculitis: have we found a culprit?

Cocaine abuse is relatively common in our society. To enhance profitability and acceptability of the product, it is not uncommon for illicit drugs to undergo several processes. The Drug Enforcement Agency (DEA) has reported that seventy percent (70%) of cocaine seized at USA borders has been adulterated with levamisole, previously used as chemotherapeutic and immunomodulator for several conditions. Among the side effects of levamisole-adulterated cocaine, necrotizing vasculitis is the more dramatic. We report three cases of necrotizing vasculitis associated with antineutrophils cytoplasmic antibodies (ANCAs) positivity, linked to the use of cocaine. To our knowledge, these are the first cases of cocaine induced vasculitis reported in the Caribbean.

Horner's syndrome: Herald of a ticking bomb.

Horner's syndrome is a clinical syndrome caused by damage to the cervical sympathetic ganglia. We discuss a case with classic signs of Horner's syndrome in an intravenous drug user with a right septic subclavian artery pseudoaneurysm. This case highlights that with the increasing intravenous drug use, this rare presentation of HS may become more common.

A resident research director can improve internal medicine resident research productivity.

BACKGROUND: Resident participation in research projects is felt to be an important component of internal medicine residency training, and accreditation organizations require that residency programs show that their residents and faculty participate in scholarly activity. PURPOSE: To determine the impact of a Resident Research Director (RRD) on scholarly productivity of our internal medicine residents. METHODS: We reviewed the number of presentations and publications of all residents from our institution over a 10-year study period (1992-2001). We used a historical control, comparing resident presentations and publications 5 years before (1992-1996) and after (1997-2001) implementation of the RRD position. We compared cohorts in terms of number of individuals in Alpha Omega Alpha and the number of individuals coming from a top 50 medical school as baseline measurements. We also compared these cohorts in regards to faculty to learner ratio, percentage of residents applying for fellowship, and American Board of Internal Medicine Certifying Examination performance. The Mann-Whitney U test was used for statistical inferences. Eighty-nine residents trained at our institution during the study period. RESULTS: There was a significant increase in the number of regional and national presentations as well as publications after instituting the RRD position. CONCLUSION: Our analysis suggests that an RRD can enhance resident scholarly productivity.

Military internal medicine resident performance on the American Board of Internal Medicine Certifying Examination.

The mission of military graduate medical education in internal medicine is to produce high-quality military internists prepared to practice in military environments. Board certification in internal medicine is an important outcome of internal medicine residency training. The American Board of Internal Medicine Certifying Examination (ABIMCE) first-taker pass rate of the graduates of an internal medicine residency program is a key measure of the quality of the program. We compared the ABIMCE first-taker pass rates for military and civilian internal medicine residency program graduates. Military internal medicine residency graduates had higher first-taker pass rates than their civilian counterparts. This is likely a reflection of the high-quality residents and the faculty at military programs. These results support the notion that military internal medicine residency programs continue to fulfill their mission of training high-quality internists.
