Next-generation Mobile Cardiac Telemetry: Clinical Value of Combining Electrocardiographic and Physiologic Parameters.

The ZOLL Arrhythmia Monitoring System, a mobile cardiac telemetry (MCT) device from ZOLL Corporation (Chelmsford, MA, USA), records single-channel electrocardiogram (ECG) signals, heart rate, activity, respiratory rate, and posture. Comprehensive reporting from these multiple biometrics may provide a global evaluation of arrhythmic or other cardiovascular risks in individual patients and insights into the patient's overall wellness and health status. The objective of the study was to evaluate the physician-perceived utility of adding biometric data to the traditional ECG-only-based assessment and subject-reported symptoms.

Co-axial computed tomography for optimizing orthodontic miniscrew implant size and site of placement.

Purpose: Absolute anchorage has been a critical aspect in orthodontics. Quantity and quality is a critical factor MSI placement. The present study was designed using a spiral computed tomography to assess the bone availability and clinically assess the optimized position and site for MSI placement in the posterior region.

Miniscrew design and bone response: defining a correlation.

Aim: This prospective clinical trial aims at correlating miniscrew implant (MSI) micro/macro architecture, the method of placement, and biologic markers in peri-MSI crevicular fluid (PMICF) as indicators of bone response. A comparative evaluation of surface morphology of the MSIs before placement and after retrieval defines a correlation between the architecture of the MSIs and the bone- implant contact ratio.

Methods: Two types of MSIs (hybrid and cylindric) were placed in ten patients using a split-mouth technique with the aid of a restricted random number table.

Myocardial involvement in rocky mountain spotted fever: a case report and review.

Rocky Mountain Spotted Fever (RMSF), caused by Rickettia rickettsii, is a serious tickborne illness that is endemic in the southeastern United States. Although it is most commonly known as a cause of fever and rash, it can have systemic manifestations. The myocardium may rarely be involved, with symptoms that can mimic those of acute coronary syndromes.

Hypercalcemia caused by iatrogenic hypervitaminosis A.

Vitamin A toxicity produces protean clinical manifestations involving a wide variety of tissues and systems. Hypercalcemia can occasionally be associated with high vitamin A levels, but is rare. In this report we describe a patient who was receiving a commercially prepared enteral feeding formula for 2 years.

Idiopathic pneumonia syndrome after syngeneic bone marrow transplant in mice.

Idiopathic pneumonia syndrome is characterized by noninfectious diffuse lung injury after myeloablative chemotherapy and bone marrow transplant. Because little is known about its pathogenesis after autologous-based regimens, we have developed a murine model that closely mimics the human lung disease process. Using an autologous regimen similar to that used for patients with metastatic breast cancer, mice developed pulmonary injury as early as 1 day posttransplant.

Fatal re-expansion pulmonary edema associated with increased lung IL-8 levels following high-dose chemotherapy and autologous stem cell transplant.

Re-expansion pulmonary edema (REPE) leading to hypoxic respiratory failure and death occurred following a unilateral low-volume (750 ml) thoracentesis in a young patient 8 days after high-dose chemotherapy and autologous stem cell transplantation (HDC/ASCT) for advanced-stage breast cancer. A higher volume (1,000 ml) thoracentesis from the contralateral lung, 2 weeks prior to HDC/ASCT, showed no clinical consequences. We have recently demonstrated increased levels of inflammatory cytokines in the lungs of patients following HDC/ASCT, a finding which may predispose them to exaggerated inflammatory lung injury.
