OBJECTIVE Post-lumbar puncture headaches (PLPHs) are a common complication of diagnostic lumbar punctures (LPs) caused by a persistent leak of spinal fluid from the dural puncture site. We conducted a prospective study to determine risk factors associated with PLPHs in the neurology outpatient setting. METHODS Clinical information from all diagnostic LPs(More)
OBJECTIVE To explore the safety and effectiveness of high-dose cyclophosphamide (HiCy) without bone marrow transplantation in patients with aggressive multiple sclerosis (MS). DESIGN A 2-year open-label trial of patients with aggressive relapsing-remitting multiple sclerosis (RRMS) given an immunoablative regimen of HiCy (50 mg/kg/d for 4 consecutive(More)
The current incidence estimate of 40 traumatic spinal cord injuries (TSCI) per million population/year in the United States (U.S.) is based on data from the 1990s. We sought to update the incidence and epidemiology of TSCI in U.S adults by using the Nationwide Emergency Department Sample (NEDS), the largest all-payer emergency department (ED) database in(More)
Major depressive disorder is the most common neuropsychiatric complication in human immunodeficiency virus (HIV) infections and is associated with worse clinical outcomes. We determined if detectable cerebrospinal fluid (CSF) HIV ribonucleic acid (RNA) at threshold ≥50 copies/ml is associated with increased risk of depression. The CNS HIV Anti-Retroviral(More)
HIV infection, depression, and cocaine use are independently associated with increased inflammatory signal production. There is increasing evidence about the role of inflammation in depression. In HIV disease, cocaine use may increase disease progression as well as alter T cell functioning resulting in cytokine activation and thereby increasing(More)
BACKGROUND Staging of disease severity is useful for prognosis, decision-making and resource planning. However, no commonly used, validated staging system exists for amyotrophic lateral sclerosis (ALS). Our purpose was to develop an ALS staging system (ALS Milano-Torino Staging) that captures the observed progressive loss of independence and function. (More)
Detectable human immunodeficiency virus (HIV) RNA in the cerebrospinal fluid (CSF) is associated with central nervous system (CNS) complications. We developed the CSF HIV risk score through prediction modeling to estimate the risk of detectable CSF HIV RNA (threshold >50 copies/mL) to help identify persons who might benefit most from CSF monitoring. We used(More)
This study was conducted to aid in the development of a multidisciplinary care center for patients with transverse myelitis. We surveyed the parents of 20 children diagnosed with transverse myelitis between the ages of 0.5 and 21 years to understand their experiences in navigating the health care system. We analyzed acute care events and long-term follow-up(More)
BACKGROUND Previous studies have described stabilization of aggressive multiple sclerosis (MS) with one-time induction therapy with high-dose cyclophosphamide (HiCy). The long-term benefit of this stabilization followed by conventional therapy has not been explored. OBJECTIVE The objective of this study was to evaluate the safety and clinical outcomes(More)
