Does smoking status affect multidisciplinary pain facility treatment outcome?

Objectives: Smoking may be a major problem in chronic low back pain (LBP) patients. The goal of this study was to determine whether smoking status affected multidisciplinary pain facility treatment outcome.

Design: As part of a grant study, chronic LBP patients identified themselves as either current smokers (N = 81) or current nonsmokers (N = 140), and were compared by chi-square for employment status at 1, 6, 12, and 24 months after multidisciplinary pain facility treatment.

What percentage of chronic nonmalignant pain patients exposed to chronic opioid analgesic therapy develop abuse/addiction and/or aberrant drug-related behaviors? A structured evidence-based review.

Design: This is a structured evidence-based review of all available studies on the development of abuse/addiction and aberrant drug-related behaviors (ADRBs) in chronic pain patients (CPPs) with nonmalignant pain on exposure to chronic opioid analgesic therapy (COAT).

Objectives: To determine what percentage of CPPs develop abuse/addiction and/or ADRBs on COAT exposure.

Method: Computer and manual literature searches yielded 79 references that addressed this area of study.

Can the neuropathic pain scale discriminate between non-neuropathic and neuropathic pain?

Objectives: 1) To determine if the neuropathic pain scale (NPS) can be used to classify chronic pain patients (CPPs) as having primarily neuropathic vs non-neuropathic pain, and furthermore; 2) to determine what, if any, cut-off score can be used to reliably make this determination.

Design: A total of 305 CPPs consecutive admissions to The Rosomoff Pain Center were administered the NPS and were assigned a diagnosis according to the physical examination and all available test results. CPPs with a diagnosis of chronic radiculopathy and spondylolysis/degenerative arthritis were segregated into two groups for the purposes of having a group representative of neuropathic pain (chronic radiculopathy) and non-neuropathic pain (spondylolysis/degenerative arthritis).

Variables associated with current smoking status in chronic pain patients.

Objectives: Smokers may report more pain and may be at greater risk for psychiatric comorbidity. Smoking may be a major problem in chronic pain patients (CPPs). The goal of this study was to determine if pain and psychiatric comorbidity are associated with smoking status in CPPs.

Medicolegal rounds: medicolegal issues and alleged breaches of standards of medical care in a patient motor vehicle accident allegedly related to chronic opioid analgesic therapy.

The objective of this medicolegal case report is to present the details of the case of a chronic pain patient (CPP) who was placed on chronic opioid analgesic therapy (COAT) and was involved in a motor vehicle accident, alleged in litigation to be related to COAT. COAT standards are in a process of evolution, and this process is influenced by recent literature developments. We aim to present both the plaintiffs and defendant's expert witnesses' opinions on whether the defendant physician fell below the "standard" in allowing the CPP to drive.

Chronic pain and the measurement of personality: do states influence traits?

Study Design: This is a structured evidence-based review of all available studies on the effect of pain, (a state phenomenon) on the measurement of personality characteristics (a trait phenomenon).

Objectives: To determine whether pain treatment changes trait scores.

Summary Of Background Data: Recent evidence from the psychiatric literature indicates that the measurement of personality characteristics (traits) can be affected or changed by the presence of state psychiatric disorders, for example, depression.

Lidocaine 5% patch: an open-label naturalistic chronic pain treatment trial and prediction of response.

Objective: There have been a few open-label nonplacebo reports on the successful use of lidocaine 5% patch (L5P) for other types of pain besides postherpetic neuralgia, such as chronic low back pain. With the these reports, we began to utilize L5P routinely for chronic pain patients (CPPs) with various pain diagnoses. The purpose of this report was to describe the results of a retrospective review of this open-label naturalistic L5P chronic pain treatment trial and to attempt to delineate predictors of perceived clinical response.

Multidisciplinary pain facility treatment outcome for pain-associated fatigue.

Objectives: Fatigue is frequently found in chronic pain patients (CPPs) and may be etiologically related to the presence of pain. Fishbain et al. have recently demonstrated that chronic low back pain (LBP) and chronic neck pain patients are more fatigued than controls.

Does the conscious exaggeration scale detect deception within patients with chronic pain alleged to have secondary gain?

Objectives: The illness behavior questionnaire (IBQ) is a test battery developed by Pilowsky to detect what he has termed abnormal illness behavior, which includes malingering. The IBQ has been widely utilized in patients with chronic pain (PWCP). Clayer developed a 21-item scale out of the IBQ, which he termed the conscious exaggeration (CE) scale.

Relationships between functional capacity measures and baseline psychological measures in chronic pain patients.

The extent to which baseline psychological measures, pain, and compensation status are related to admission and posttreatment functional capacity and employment outcome was investigated. Four pass/fail functional capacity tests based on the DOT (Dictionary of Occupational Titles) classification system and previously shown to be predictive of treatment outcome in chronic pain patients were analyzed in relation to baseline measures of depression, state and trait anxiety, and perceived stress. Statistical tests of all measures with employment level at admission to treatment, 1 month follow-up and at long-term follow-up were also performed.

Are opioid-dependent/tolerant patients impaired in driving-related skills? A structured evidence-based review.

Previous reviewers have concluded that opioids cause dose-related impairment in opioid-naive volunteers on psychomotor skills related to driving. Data relating to opioid-dependent/tolerant patients have not yet been reviewed. To determine what evidence, if any, exists for or against opioid-related driving skill impairment in opioid-dependent/tolerant patients, we performed a structured evidence-based review of all available studies addressing the issue of whether opioid-dependent/tolerant patients are impaired in driving-related skills.

Physical findings in patients with chronic intractable benign pain of the neck and/or back.

Chronic intractable benign pain (CIBP) is defined as non-neoplastic pain of greater than 6 months duration without objective physical findings and known nociceptive peripheral input. To test the CIBP concept, 283 consecutive chronic pain patients were examined independently by a neurosurgeon and physiatrist and only congruent physical findings were coded. Because they did not fit the CIBP definition, patients with the following primary treatment diagnoses were eliminated: degenerative disease of the spine and spinal stenosis; degenerative disease of the hips; radiculopathy; malignancy; deafferentation pain; and miscellaneous.

Münchausen syndrome presenting with chronic pain: case report.

A factitious disorder is one that has been fabricated or simulated by the patient. Münchausen syndrome is a subtype of factitious disorder. This syndrome has not previously been described in relationship to chronic pain/chronic pain treatment units.

Compensation and non-compensation chronic pain patients compared for DSM-III operational diagnoses.

Two hundred and eighty-three mixed chronic pain patients, consecutive admissions, were diagnostically evaluated as per DSM-III, Axis I, Axis II or personality type psychiatric operational criteria. Controlling for primary organic treatment diagnosis, age and race, statistical comparisons were made between male compensation patients (n = 93) and male non-compensation patients (n = 23) and between female compensation patients (n = 38) and female non-compensation patients (n = 28) for all DSM-III diagnoses. Male compensation patients were significantly overrepresented for these diagnostic groups: conversion disorder (somatosensory type); combined personality disorders; and passive-aggressive personality disorder.

Male and female chronic pain patients categorized by DSM-III psychiatric diagnostic criteria.

Two hundred and eighty-three chronic pain patients, consecutive admissions to the Comprehensive Pain Center of the University of Miami School of Medicine, received an extensive psychiatric evaluation based upon the American Psychiatric Association, Diagnostic and Statistical Manual of Mental Disorders (DSM-III) criteria and flowsheets. All patients received the following type of diagnoses: DSM-III axis I; DSM-III axis II, and personality type. The distribution of assigned diagnoses for the entire patient sample was reviewed and a statistical comparison between male and female patients was performed with regards to the prevalence of each diagnosis.
