Chronic axial neck pain and cervicogenic headache are common problems, and there have been significant advances in the understanding of the etiology and treatment of each. The severity and duration of pain drives the process. For patients who have had slight to moderate pain that has been present for less than 6 months and have no significant motor loss, strength training of anterior, posterior, and interscapular muscle groups coupled with body mechanics training is prescribed. ⋯ For patients with one or two level disc degeneration that has not responded, a psychologic evaluation and discography is recommended. If there are no significant psychologic abnormalities, and one or two (rarely three) painful discs, surgical consultation is recommended. Adjunctive low-dose opioid analgesics, nonsteroidal anti-inflammatory drugs, and perhaps tricyclic antidepressants are used to supplement the program at mid- and late stages.

Migraine is a common, chronic neurologic disorder that affects approximately 12% of the adult population in Western countries. Once migraine is diagnosed, illness severity must be assessed. Clinicians and patients should then work together to develop a treatment plan based on patient needs and preferences. ⋯ A variety of behavioral interventions are helpful. The clinician has an armamentarium of ever-expanding variety of medications. With experience, clinicians can match individual patient needs with the specific characteristics of a drug to optimize therapeutic benefit.

Chronic hip pain is often a debilitating problem and many patients are not good surgical candidates. Furthermore, hip replacement surgery has significant associated risks. We offer a conservative approach to hip replacement using radiofrequency lesioning. ⋯ Percutaneous radiofrequency lesioning of the sensory branches of the obturator and femoral nerves appears to be a safe alternative to hip replacement, especially in those patients where surgery is not an option. Further studies are needed to confirm our results.

Bronchiolar pathologic lesions result from the interplay between inflammatory and mesenchymal cells following injury to bronchioles. Offending agents include viruses, bacteria, fungi, cigarette smoke, toxic inhalants, inorganic dusts, allergens, and systemic or localized autoimmune or inflammatory processes. Bronchiolar pathologic lesions also arise in the context of allograft transplantation and pathology of the large airways and in the setting of an idiopathic disorder. ⋯ After a survey of the normal histology of bronchioles, we present a pragmatic classification that reflects the spectrum of bronchiolar pathology, illustrating the intimate interdependence of clinical, radiological, and pathologic findings in assessing the significance of bronchiolar lesions. This classification is intended to be applicable to surgical pathology material that can be correlated with clinical disease syndromes. It includes asthma-associated bronchiolar changes, chronic bronchitis/emphysema-associated bronchiolar changes, cellular bronchiolitis, respiratory bronchiolitis, bronchiolitis obliterans with intraluminal polyps/ BOOP, constrictive bronchiolitis, mineral dust small airway disease, peribronchiolar fibrosis and bronchiolar metaplasia, and bronchiolocentric nodules.

The lifetime prevalence of spinal pain has been reported as 65% to 80% in the neck and low back. In the US each year, 500,000 - 1,000,000 spine surgeries and 2 to 5 million interventional procedures are estimated to be performed. The burden created by chronic pain is enormous on the patient and society. ⋯ The optimal course of care requires an integrated delivery system involving a variety of specialists. Due to the complexities of diagnosis and management, patients are best managed utilizing a multidisciplinary approach under an umbrella of services offered by a spinal diagnostic and interdisciplinary pain center. This review identifies various pain syndromes and conditions and provides a model for the establishment of an interdisciplinary pain center as well as the resources, guidelines, and infrastructure required for operating a successful pain center in any setting; free-standing, hospital-based, or academic.
