A Young Boy With Hemophagocytic Lymphohistiocytosis Presenting With Vaccine-Related Granulomatous Dermatitis: A Case Report and Literature Review.

Cutaneous eruptions associated with hemophagocytic lymphohistiocytosis (HLH) have been reported in 6%-63% of patients. Clinical findings of these skin lesions vary widely and include maculopapular rashes, ulcers, and violaceous nodules. Corresponding histologic findings are also variable and are considered nonspecific.

Health providers induced iatrogenic delusions of infestation.

Patients that suffer from factitial dermatosis mutilate their skin, often lacking any consciousness of self-injury, attributing the resulting lesions to spontaneous development. The case hereby described shows how the health providers' interventions led a patient from a baseline undiagnosed factitious disorder to frank delusions of infestation with , and a relentless search for antibiotic treatments. We highlight the need for educating health practitioners on the characteristics of psycho-cutaneous disorders.

Clinical resolution of pemphigus vulgaris on rituximab.

Although significant progress has been made for the treatment of pemphigus vulgaris (PV) with rituximab (RTX), a consensus remains to be determined for standard treatment protocol, regarding optimal dosing, infusion regimen, and use of concomitant immunotherapy to achieve safe, effective, and rapid clinical response. We describe a patient with pemphigus vulgaris treated with high dose rituximab with the rheumatoid arthritis protocol along with intravenous immunoglobulin therapy. This case provides evidence towards the growing body of research needed to modify and improve treatment for pemphigus using rituximab.

Laugier-Hunziker syndrome: a case of asymptomatic mucosal and acral hyperpigmentation.

Laugier-Hunziker syndrome (LHS) is a rare condition characterized by acquired hyperpigmentation involving the lips, oral mucosa, acral surfaces, nails and perineum. While patients with LHS may manifest pigmentation in all of the aforementioned areas, most present with pigmentation localized to only a few of these anatomical sites. We herein report a patient exhibiting the characteristic pigment distribution pattern associated with LHS.

The Relationship Between High Pulse Pressure and Low Ankle-Brachial Index. Potential Utility in Screening for Peripheral Artery Disease in Population-Based Studies.

Introduction: The ankle-brachial index (ABI) is a reliable screening procedure for peripheral artery disease detection. However, ABI testing is time-consuming and requires trained personnel, which may preclude its routine use in population-based surveys. Preliminary data suggest a relationship between ABI values and pulse pressure (PP) levels.

The association of ankle-brachial index with silent cerebral small vessel disease: results of the Atahualpa Project.

Background: An abnormal ankle-brachial index has been associated with overt stroke and coronary heart disease, but little is known about its relationship with silent cerebral small vessel disease.

Aim: To assess the value of ankle-brachial index as a predictor of silent small vessel disease in an Ecuadorian geriatric population.

Methods: Stroke-free Atahualpa residents aged ≥60 years were identified during a door-to-door survey.

Prevalence, correlates, and prognosis of peripheral artery disease in rural ecuador-rationale, protocol, and phase I results of a population-based survey: an atahualpa project-ancillary study.

Background. Little is known on the prevalence of peripheral artery disease (PAD) in developing countries. Study design.

Utilization of trained volunteers decreases 30-day readmissions for heart failure.

Background: This study evaluated the effectiveness of using trained volunteer staff in reducing 30-day readmissions of congestive heart failure (CHF) patients.Methods: From June 2010 to December 2010, 137 patients (mean age 73 years) hospitalized for CHF were randomly assigned to either: an interventional arm (arm A) receiving dietary and pharmacologic education by a trained volunteer, follow-up telephone calls within 48 hours, and a month of weekly calls; ora control arm (arm B) receiving standard care. Primary outcomes were 30-day readmission rates for CHF and worsening New York Heart Association (NYHA) functional classification; composite and all-cause mortality were secondary outcomes.
