PURPOSE Sickle cell disease (SCD) is the most common and serious form of an inherited blood disorder that lead to higher risk of early mortality. SCD patients are at high risk for developing multiorgan acute and chronic complications linked with significant morbidity and mortality. Some of the ophthalmological complications of SCD include retinal changes, refractive errors, vitreous hemorrhage,...

Sperm DNA fragmentation is being increasingly recognized as an important cause of infertility. We herein describe the Sperm Chromatin Dispersion (SCD) test, a novel assay for sperm DNA fragmentation in semen. The SCD test is based on the principle that sperm with fragmented DNA fail to produce the characteristic halo of dispersed DNA loops that is observed in sperm with non-fragmented DNA, foll...

HYPOTHESIS Power reflectance (PR) measurements in ears with superior canal dehiscence (SCD) have a characteristic pattern, the detection of which can assist in diagnosis. BACKGROUND The aim of this study was to determine whether PR coupled with a novel detection algorithm can perform well as a fast, noninvasive, and easy screening test for SCD. The screening test aimed to determine whether pa...

Aims To test the value of Periodic Repolarization Dynamics (PRD), a recently validated electrocardiographic marker of sympathetic activity, as a novel approach to predict sudden cardiac death (SCD) and non-sudden cardiac death (N-SCD) and to improve identification of patients that profit from ICD-implantation. Methods and results We included 856 post-infarction patients with left-ventricular ...

OBJECTIVE Sickle cell disease (SCD) conveys a high risk of neuropsychological impairment due to chronic anemia, hypoxemia, cerebrovascular ischemia and stroke, in addition to causing pain and other biomedical complications. Few families accessed neuropsychological testing via the traditional referral system. In this paper, we describe a successful alternative strategy for addressing cognitive a...

BACKGROUND Sudden cardiac death (SCD) is the leading cause of death in maintenance hemodialysis (HD) patients, but there is little information about underlying risk factors. OBJECTIVES Evaluate the association between clinical and echocardiographic variables with SCD on HD patients. METHODS Retrospective nested case-control study on chronic HD patients who were prospectively followed. The p...

BACKGROUND Pulmonary complications are a major cause of morbidity and mortality in sickle cell disease (SCD). The relationship of asthma with SCD and acute chest syndrome (ACS) remains uncertain. A study was undertaken to test the hypotheses that asthma and bronchial hyperreactivity (BHR) are more common in children with SCD than in ethnic matched controls and that SCD children with atopic asth...

In the daily practice of forensic pathology, sudden cardiac death (SCD) is a diagnostic challenge. Our aim was to determine the usefulness of blood biomarkers [creatine kinase CK-MB, myoglobin, troponins I and T (cTn-I and T), and lactate dehydrogenase] measured by immunoassay technique, in the postmortem diagnosis of SCD. Two groups were compared, 20 corpses with SCD and 8 controls. Statistica...

OBJECTIVE To compare the neuropsychological functioning of children with sickle cell disease (SCD) with no evidence of overt clinical stroke to that of classmates without a chronic illness matched on gender, race, and age. We examined both overall level of performance and patterns of performance utilizing empirically derived construct scores of key domains of neurocognitive functioning. METHO...
