ABSTRACT

Strongyloidiasis is an emerging parasitic infection with intriguing epidemiology, presentation, and clinical management. We report a case of hyperinfection syndrome complicated by E. coli bacteremia and meningitis with one of the isolates showing a unique resistance pattern recently being recognized. This report describes the aspect of invasive bacterial infections in strongyloidiasis and highlights the unique susceptibility pattern of the E. coli isolate and the extreme caution required during the antibiotic therapy.

ABSTRACT

HIV has been linked to several autoimmune disorders since its emergence in the 1980s. By affecting different cells and pathways in the immune system, HIV induces the development of certain autoimmune diseases while prohibiting the emergence of others. Dermatomyositis has been rarely described in patients with HIV. We present a case of dermatomyositis in a patient with HIV and explore the pathogenesis of autoimmune disorders in HIV focusing on dermatomyositis.

ABSTRACT

An 83-year-old female patient with rheumatoid arthritis and hypertension presented to the emergency department with fever and chills of 1 day duration. On examination, temperature was 100.9 F, heart rate 111/min and she had orthostatic hypotension. Laboratory tests showed elevated blood urea nitrogen and white cell count. The patient underwent treatment for symptomatic urinary tract infection and while her fever and leucocytosis resolved, tachycardia persisted. An EKG done showed T inversions in leads II, III, arteriovenous fistula, V2 and V3. Troponin-I was elevated. Nuclear stress test revealed apical wall motion abnormality confirming myocardial infarction. Ewing's tests were carried out at bedside and these diagnosed severe autonomic neuropathy. Rheumatoid arthritis can cause cardiac autonomic neuropathy from chronic inflammation. This case entails the importance of assessing and detecting cardiac autonomic neuropathy in chronic inflammatory conditions, and the need to be cautious of acute coronary events in these patients, even for minimal or no symptoms.

ABSTRACT

Patients with severe aortic stenosis who are at high risk for open-heart surgery might be candidates for transcatheter aortic valve replacement (TAVR). To our knowledge, this is the first report of Streptococcus viridans endocarditis that caused prosthetic valve obstruction after TAVR. A 77-year-old man who had undergone TAVR 17 months earlier was admitted because of evidence of prosthetic valve endocarditis. A transthoracic echocardiogram revealed a substantial increase in the transvalvular peak gradient and mean gradient in comparison with an echocardiogram of 7 months earlier. A transesophageal echocardiogram showed a 1.5-cm vegetation obstructing the valve. Blood cultures yielded penicillin-sensitive S. viridans. The patient was hemodynamically stable and was initially treated with vancomycin because of his previous penicillin allergy. Subsequent therapy with levofloxacin, oral penicillin (after a negative penicillin skin test), and intravenous penicillin eliminated the symptoms of the infection. Transcatheter aortic valve replacement is a relatively new procedure, and sequelae are still being discovered. We recommend that physicians consider obstructive endocarditis as one of these.

ABSTRACT

Invasive pulmonary aspergillosis (IPA) is a severe fungal infection with a high mortality rate. The incidence of IPA is on the rise due to an increase in the number of patients undergoing transplants and receiving chemotherapy and immunosuppressive therapy. Diagnosis is challenging due to the non-specific nature of symptoms. Voriconazole is the mainstay of therapy. We present a case of an elderly woman presenting with acute bronchitis and asthma exacerbation, who succumbed to overwhelming IPA. It is uncommon for IPA to develop in patients on short-term steroid therapy for asthma exacerbation. The possibility of aspergillosis in immunocompetent patients should be considered in those on systemic steroids and deteriorating pulmonary functions.

ABSTRACT

OBJECTIVE: Cardiovascular disease (CVD) is largely preventable through appropriate risk-factor modification. We sought to compare effects of comprehensive cardiac risk factor screening with and without computed tomography (CT) imaging of the coronary arteries on behavior change related to cardiac risk in postmenopausal women. STUDY DESIGN AND SETTING: 56 postmenopausal women were randomized to alternative screening programs and followed for 1 year. RESULTS: Subjects randomized (n=26) to the CT imaging group were shown images of their coronary arteries and received an interpretation from a radiologist. Most subjects in the CT group had a very low-risk (73.1%) coronary calcification score at baseline. Systolic blood pressure, total cholesterol, triglyceride, LDL, and cholesterol/HDL ratio declined significantly in the conventional screening group, but not in the CT imaging group (P<0.05). As compared to baseline values, study participation lead to significant reductions in total cholesterol, HDL, LDL, and blood pressure at 6 months (P<0.05) and triglyceride (P<0.05) at 12 months. CONCLUSIONS: CVD risk-screening programs can facilitate cardiac risk reduction in women, but these data do not support an independent benefit of coronary CT imaging in a low-to-moderate risk group. The possibility of a deleterious effect of imaging on patient commitment to lifestyle changes is suggested.
