Design: Retrospective cohort study.

Setting: Single academic medical center.

Preoperative Alcohol Use, Postoperative Pain, and Opioid Use After Coronary Artery Bypass Surgery.

Objectives: Chronic alcohol use is associated with chronic pain and increased opioid consumption. The association between chronic alcohol use and acute postoperative pain has been studied minimally. The authors' objective was to explore the association among preoperative alcohol use, postoperative pain, and opioid consumption after coronary artery bypass grafting (CABG).

Bedside Clinician's Guide to Pulmonary Artery Catheters.

Background: Pulmonary artery catheters provide important information about cardiac function, mixed venous oxygenation, and right-sided pressures and potentially provide temporary pacing ability.

Objective: To provide bedside clinicians with guidance for techniques to insert right heart monitors and devices, describe risk factors for difficult insertion and contraindications to placement, and provide updates on new technologies that may be encountered in the intensive care unit.

Methods: An extensive literature review was performed.

Preoperative Assessment and Optimization of Cardiopulmonary Disease in Noncardiac Surgery.

More than 50 million surgical procedures are carried out every year in the United States with the estimated risk of major adverse cardiac events perioperatively between 1.4 and 3.9%.

Perioperative Considerations Regarding Sex in Solid Organ Transplantation.

Sex plays a role in all stages of the organ transplant process, including listing, sex/size matching of organs, complications, graft survival, and mortality. Sex-related differences in organ transplantation are likely multifactorial related to biological and social characteristics. More information is needed to determine how sex-related differences can lead to improved outcomes for future donors and recipients of solid organs.

Drowning hazard with deep brain stimulation: case report.

The caudal zona incerta target within the posterior subthalamic area is an investigational site for deep brain stimulation (DBS) in Parkinson disease (PD) and tremor. The authors report on a patient with tremor-predominant PD who, despite excellent tremor control and an otherwise normal neurological examination, exhibited profound difficulty swimming during stimulation. Over the last 20 years, anecdotal reports have been received of 3 other patients with PD who underwent thalamic or pallidal lesioning or DBS surgery performed at the authors' center and subsequently drowned.

Interactive effects of GPI stimulation and levodopa on postural control in Parkinson's disease.

Introduction: Postural instability is a major source of disability in idiopathic Parkinson's disease (IPD). Deep brain stimulation of the globus pallidus internus (GPI-DBS) improves clinician-rated balance control but there have been few quantitative studies of its interactive effects with levodopa (L-DOPA). The purpose of this study was to compare the short-term and interactive effects of GPI-DBS and L-DOPA on objective measures of postural stability in patients with longstanding IPD.

Paraspinal and scapular myopathy associated with scleroderma.

Objective: To describe a form of inflammatory myopathy with prominent involvement of the paraspinal and scapular muscles in patients with scleroderma.

Methods: Review of clinical records, laboratory investigations, and muscle biopsies.

Results: Patients presented with a "dropped head" resulting from weakness of the posterior cervical muscles (three cases) or camptocormia ("bent spine") resulting from weakness of the paraspinal muscles (two cases) and variable weakness and atrophy of shoulder girdle muscles with mild or absent pelvic girdle involvement.

Improvement in aerobic capacity after an exercise program in sporadic inclusion body myositis.

Objectives: The study aimed to investigate the effects of a combined functional and aerobic exercise program on aerobic capacity, muscle strength, and functional mobility in a group of patients with sporadic inclusion body myositis (IBM).

Methods: Aerobic capacity, muscle strength, and functional capacity assessments were conducted on 7 participants with sporadic IBM before and after a 12-week exercise program, which included resistance exercises and aerobic stationary cycling 3 times per week on alternative days.

Results: Aerobic capacity of the group increased significantly by 38%, and significant strength improvements were observed in 4 of the muscle groups tested (P < 0.

Spike-timing-related plasticity is preserved in Parkinson's disease and is enhanced by dopamine: evidence from transcranial magnetic stimulation.

We sought to investigate the effects of dopamine on motor cortical plasticity in Parkinson's disease (PD) using a novel interventional transcranial magnetic stimulation protocol that targets spike-timing-dependent plasticity (iTMS). Six patients (3F, mean age 62 years) with mild-moderate PD (mean disease duration 6 years, UPDRS-off 13, UPDRS-on 3, H&Y stage 2, daily levodopa dosage 450 mg) were studied off and on levodopa on separate days. Paired TMS pulses at resting motor threshold with an inter-stimulus interval of 1.

Globus pallidus stimulation improves both motor and nonmotor aspects of quality of life in advanced Parkinson's disease.

Our purpose was to measure the change in quality of life (QoL) following deep brain stimulation of the globus pallidus interna (GPi-DBS) in advanced Parkinson 's disease (PD), and identifies any associations with changes in motor features of the disease. Eleven patients (age range 54-69 years, 2 women) underwent GPi-DBS (4 unilateral, 7 bilateral). Outcome measures included assessment of PD-specific QoL (mean 8 months postsurgery) using the PDQ-39 questionnaire, and standard motor assessments.

Familial inclusion body myositis in a mother and son with different ancestral MHC haplotypes.

An Ashkenazi Jewish family in which the mother and a son both have inclusion body myositis (IBM) is reported. The condition developed at an earlier age and was more rapidly progressive and less responsive to treatment in the son than in the mother or other IBM patients in our clinic. Genetic analysis showed that the mother carried alleles of the 8.

Motor cortex reorganisation in Parkinson's disease.

Transcranial magnetic stimulation mapping of the motor cortical projection to the hand was performed in a group of patients with Parkinson's disease (PD) of variable duration to determine whether there is evidence of cortical reorganisation. Map shifts were found in the majority of PD cases (12/15), in untreated early cases as well as treated cases of longer duration, and there was a correlation between inter-side difference in the severity of PD symptoms (Unified Parkinson's Disease Rating Scale) and interhemispheric map displacement (r=0.60; P=0.

Blinded placebo crossover study of gabapentin in primary orthostatic tremor.

Primary orthostatic tremor (OT) is a rare but disabling condition characterized by leg tremor and feelings of instability during stance. Previous studies have reported a reduction in OT symptoms with gabapentin treatment. In this study, we report on the benefits of gabapentin treatment in a double-blind placebo-controlled crossover study of 6 OT patients.

Gabapentin can improve postural stability and quality of life in primary orthostatic tremor.

Primary orthostatic tremor (OT) is characterized by leg tremor and instability on standing. High frequency (13-18 Hz) tremor bursting is present in leg muscles during stance, and posturography has shown greater than normal sway. We report on an open-label add-on study of gabapentin in 6 patients with OT.

School-based health centers and academic performance: research, challenges, and recommendations.

School-based health centers (SBHCs) provide physical and mental health services on school campuses to improve student health status, and thereby potentially facilitate student academic success. With a growing emphasis on school accountability and the simultaneous dwindling of resources at the federal, state, and local levels, SBHCs face increasing pressures from school administrators and funders to document their impact on student academic achievement. This article reviews the methods, findings, and limitations of studies that have examined the relationship between SBHCs and academic performance.

Primary writing tremor: motor cortex reorganisation and disinhibition.

Background: Primary writing tremor (PWT) is a task-specific tremor of uncertain origin. There has been debate as to whether PWT represents a variant of essential tremor or a tremulous form of focal dystonia related to writer's cramp. In writer's cramp there is evidence of changes in intracortical inhibition (ICI), as well as cortical motor reorganisation.
