To determine the long-term efficacy of IDET in the treatment of chronic lumbar discogenic pain. ⋯ IDET appears to be an effective treatment for chronic lumbar discogenic pain in a well-selected group of patients with favorable long-term outcome.

Facet or zygapophysial joint blocks are used extensively in the evaluation of chronic spinal pain. However, there is a continuing debate about the value and validity of facet joint blocks in the diagnosis of chronic spinal pain. The value of diagnostic facet joint injections may have been overlooked in the medical literature. ⋯ The diagnostic accuracy of controlled local anesthetic facet joint blocks is high in the diagnosis of chronic spinal pain.

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.

Glossopharyngeal neuralgia (GPN) is an uncommon orofacial pain syndrome. Primary GPN is idiopathic, whereas secondary GPN has identifiable causes: tonsillectomy, peritonsillar abscesses, invasive cancer, and trauma. ⋯ Pulsed mode radiofrequency lesioning is a safe, non-destructive treatment method and hence, useful in neuropathic pain conditions. We present the first case of chronic post-tonsillectomy pain (secondary glossopharyngeal neuralgia), that was successfully managed with pulsed radiofrequency lesioning.
