SPECT/CT-plethysmography--non-invasive quantitation of bone and soft tissue blood flow.

Preserved blood flow to bone and soft tissue is essential for their normal function. To date only numerous methods are suitable for direct bone blood flow (BBF) measurement. Here, we introduce a novel quantitative method for bone and soft tissue blood flow (BBF and SBF, respectively) measurement.

Hormonal and volume dysregulation in women with premenstrual syndrome.

Premenstrual syndrome (PMS) presents with emotional and physical symptoms. Although the emotional symptoms have been extensively studied, the pathophysiology of the fluid-retention symptoms is not currently known. We tested the hypothesis that the fluid regulatory mechanisms are disturbed in PMS.

Aspergillus vertebral osteomyelitis in chronic leukocyte leukemia patient diagnosed by a novel panfungal polymerase chain reaction method.

Background Context: Vertebral osteomyelitis and disciitis caused by Aspergillus spp is a rare event. Early diagnosis and early antifungal therapy are critical in improving the prognosis for these patients. The diagnosis of invasive fungal infections is, in many cases, not straightforward and requires invasive procedures so that histological examination and culture can be performed.

Use of cellular telephones and transmission of pathogens by medical staff in New York and Israel.

Hands and instruments used by healthcare workers may serve as vectors for the nosocomial transmission of microorganisms. The use of cellular telephones by medical personnel and the associated nosocomial transmission of pathogens have not been thoroughly examined. Findings from our study show that cellular telephones are commonly used by hospital personnel, even during patient contact.

Impaired cerebral CO2 vasoreactivity: association with endothelial dysfunction.

Conflicting data exist on the role of nitric oxide (NO) in cerebral blood flow (CBF) autoregulation. Previous studies involving human and animal subjects seem to indicate that NO involvement is limited to the CO(2)-dependent mechanism (chemoregulation) and not to the pressure-dependent autoregulation (mechanoregulation). We tested this hypothesis in patients with impaired endothelial function compared with healthy controls.
