Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare and potentially fatal severe cutaneous reaction, which has a delayed onset after the initiation of an inciting medication. ...After recognition and withdrawal of the causative agent, along with aggressive management, a majority of patients will have complete recovery over several months. We present a rare case of DRESS secondary to oxcarbazepine with an elevated human herpesvirus-6 titer.
Mixed Gram-negative bacterial infections represent a secondary infection, due to the underlying tinea pedis. 1 Trauma, depressed host resistance, as in diabetes mellitus or HIV disease, may also ...predispose individuals to the infection. In a multivariate analysis, disruption of the cutaneous barrier (ie, traumatic wound, toe-web intertrigo, excoriated leg dermatosis and plantar squamous lesions) and leg oedema were found to be independently associated with erysipelas of the leg. 2 For our patient, Pseudomonas aeruginosa was found to be the causative pathogen based on bacterial culture.
Opportunistic infections following immunosuppression in solid organ transplant (SOT) patients are common complications with the skin being a common sight of infection. Nontuberculous mycobacteria ...(NTM) are rare but potential causes of skin infection in SOT patients. We present a case of an adult male immunosuppressed following renal transplantation who presented with an asymptomatic rash for several months. The patient’s skin eruption consisted of erythematous papules and plaques coalescing into an annular formation. After failure of the initial empiric therapy, a punch biopsy was performed that demonstrated nerve involvement suspicious for Mycobacterium leprae. However, culture of the biopsy specimen grew acid-fast bacilli that were subsequently identified as M. haemophilum. His rash improved after a prolonged course of clarithromycin and ciprofloxacin. Both organisms are potential causes of opportunistic skin infections and can be difficult to distinguish with similar predilection for skin and other biochemical and genetic similarities. Ultimately they can be distinguished with culture as M. haemophilum will grow in culture and M. leprae will not. This case was unique due to nerve involvement on biopsy which is classically seen on biopsies of leprosy.
A 58-year-old female with a history of hypertension and asthma presented to an internist for a routine physical examination. A grade II/VI systolic ejection murmur and electrocardiogram abnormalities ...were noted. She was referred to a cardiologist for further assessment.

Incident chest pain occurred in 30.3% of 1,743 asymptomatic healthy men and women who were followed for up to 4 years. Proportions of patients who had coronary artery calcium were similar among those ...who had no chest pain, noncardiac pain, atypical pain, or cardiac chest pain. Incident chest pain is common and should be examined according to a patient’s pretest probability of developing coronary artery disease, without excessive influence of the presence of coronary artery calcium.
The authors examined the relationship between calcified coronary atherosclerosis and an array of cardiovascular risk factors in sequential logistic models to determine the extent to which these ...markers overlap in their identification of patients at risk for developing coronary heart disease. The prevalence of coronary artery calcium using electron beam computed tomography was 19.4% in this cross‐sectional study of a prospective, consecutive, screening cohort of 1999 healthy United States Army personnel (aged 39–50 years). The proportion of the total variance of coronary artery calcium explained by sequential logistic models incorporating conventional, emerging, hereditary, lifestyle, and psychosocial cardiovascular risk variables increased progressively from 9.7% to 14.5%. The best‐fit logistic model for the prediction of coronary artery calcium identified age, male gender, Framingham risk score, total cholesterol, high‐density lipoprotein cholesterol, triglycerides, smoking, a family history of coronary heart disease, white race, physical inactivity, and lower depression scores as significant independent correlates of coronary artery calcium. These data indicate that the explanatory power of models for atherosclerosis can be significantly improved with the use of emerging, heredity, lifestyle, and psychosocial factors. The large residual variance, however, supports the potential of atherosclerosis imaging to incrementally and independently identify coronary heart disease risk.
Identifying the etiology of a cutaneous eruption in the setting of an acute cluster outbreak is of utmost importance due to the inherent potential public health impact. The differential diagnosis ...ranges from innocuous arthropod bites to more concerning causes such as infection, medication reaction, and environmental exposure. We report the simultaneous presentation of 15 US Marines who presented with numerous discrete papular skin eruptions. Subsequent thorough patient evaluation and history, literature review, immunization status reconciliation, entomological assessment, site survey, and skin biopsy were performed. This case series is one of the largest reported to date of a cluster outbreak of a papular dermatitis secondary to bites from thrips (ie, insects of the order Thysanoptera).

To the Editor:
Metastatic tumors that invade the heart occur 20 to 40 times more frequently than primary tumors. Of the primary cardiac tumors, 75 percent are benign, and of these benign tumors, ...myxomas are the most common. The remaining primary cardiac tumors are malignant, the overwhelming majority of which are sarcomas. Cardiac sarcomas arise from the right side of the heart in 25 percent of reported cases, whereas myxomas arise from right-sided cardiac structures in only 5 percent of cases.
