Resolution and recurrence of anemia following repair of paraesophageal hernias.

Background: Iron deficiency anemia is a common paraesophageal hernia (PEH) symptom and may improve after repair. When present, anemia has also been proposed to be associated with an increase in length of hospital stay, morbidity, and mortality after PEH repair. This study aimed to determine anemia-related factors in patients with PEH, the rate of anemia resolution after PEH repair, and the risk of anemia recurrence when repair failed.

A virtual-pinhole PET device for improving contrast recovery and enhancing lesion detectability of a one-meter-long PET scanner: a simulation study.

This paper presents a simulation study to demonstrate that the contrast recovery coefficients (CRC) and detectability of small lesions of a one-meter-long positron emission tomography (PET) scanner can be further enhanced by the integration of high resolution virtual-pinhole (VP) PET devices. The scanner under investigation is a Siemens Biograph Vision Quadra which has an axial field-of-view (FOV) of 106 cm. The VP-PET devices contain two high-resolution flat panel detectors, each composed of 2 × 8 detector modules each of which consists of 32 × 64 lutetium-oxyorthosilicate crystals (1.

Concomitant neuroleptic malignant syndrome and diabetes insipidus.

Each year, nearly one-fifth of adults in the United States are prescribed at least one psychotropic medication. An increased trend in psychiatric polypharmacy has heightened awareness of drug-drug interactions and the tracking of adverse drug reactions. This article describes a patient who developed concomitant neuroleptic malignant syndrome (NMS) and nephrogenic diabetes insipidus during cross-titration of his antipsychotics while on lithium.

Midterm Outcomes of Endovascular Versus Open Surgical Repair of Intact Descending Thoracic Aneurysms in Patients with Connective Tissue Disorders.

Background: Data on the efficacy of endovascular thoracic endovascular aneurysm repair (TEVAR) versus open surgical repair for chronic aortic pathology in patients with connective tissue disorders are limited. In particular, few studies have examined outcomes of TEVAR versus open repair for intact descending thoracic aortic aneurysms (DTAA) in this subset of patients beyond index hospitalization. Therefore, we investigate 5-year outcomes of TEVAR and open surgical repair of intact DTAAs in patients with known connective tissue disorders.
