Several countries developed guidelines in order to provide a systematic approach for treatment of (chronic) lower back pain. The risk of suffering from (chronic) lower back pain differs significantly within the general population. A serious lack of research exists concerning the risk factor "dysfunctional behavior of the subjects in terms of acute lower back pain." ⋯ The study revealed a lack of awareness of common available guidelines and an uneven distribution of existing knowledge throughout the population. Passive coping strategies like taking pain medication or ointment therapy were favored over active coping strategies like gymnastics, physical activities, and relaxation exercises. Respondents with a higher level of education suffered significantly less often from lower back pain and tended toward active treatment strategies. Respondents with lower levels of education more often demanded passive treatment strategies. The general population, especially those with lower education, is not sufficiently aware of behavioral strategies for managing lower back pain as proposed in available guidelines.

Anatomy of the infrapatellar branch in relation to skin incisions and as the basis to treat neuropathic pain by cryodenervation.
Neuropathic knee pain, particularly of the infrapatellar branch, is an important complication of knee replacement surgery, with an incidence as high as 70%. The increasing number of elderly patients requiring knee surgery, including total knee arthroplasty (TKA), has contributed to an increase in the number of patients with this pathology. Treatment includes neurectomy, infiltration therapy, and cryodenervation. Percutaneous cryodenervation of the infrapatellar branch is a promising option. ⋯ Based on our findings, the surgeon can localize the unbranched main nerve. Compared with the current practice, our approach should allow for a lower impact on tissues and should facilitate complete pain relief through a single cryodenervation. Furthermore, we propose that the lateral parapatellar skin incision is an acceptable alternative surgical approach in knee replacement surgery because it is associated with the lowest risk of damage to the infrapatellar branch.

Persistent meningeal puncture headache (MPH) is a known complication following both intentional and unintentional puncture of the dura mater. We present a case of persistent MPH following implantation of an intrathecal drug delivery system (IDDS). Two separate epidural blood patches (EBP) were performed under radiographic guidance with contrast visualization of the epidural space on postoperative days 16 and 28, respectively. ⋯ This case illustrates a potential unique morbidity associated with the EBP in a patient with an IDDS. The report concludes with a brief review of MPH followed by a discussion of possible mechanisms underlying this complication.

Mental nerve neuropathy (MNN), colloquially referred to as numb chin syndrome, is an uncommon neurologic condition that may arise secondary to multiple local and systemic etiologies, and may mimic other pain conditions affecting the mandible. Early recognition of mental nerve neuropathy in conjunction with accurate etiologic identification is crucial, as early pain management may prevent the transition from an acute to a chronic pain condition. In this article, we will describe the clinical courses of 2 patients who presented to the pain clinic with chronic painful numbness in the mental nerve sensory distribution following dental extraction. ⋯ The objective of our article is to help clinicians identify and properly manage early stage mental nerve neuropathy. Moreover, we aim to advance general medical knowledge of this important pain medicine topic. During the process of preparing this article we reviewed all existing pertinent medical literature related to MNN.

A 39-year-old woman with no history of trauma or meningitis presented to the neurology department of our hospital with an occipital headache, neck pain, nausea, and dizziness that had worsened during the previous month. The headache worsened when sitting or standing and partially regressed when lying down. She was diagnosed with spontaneous intracranial hypotension (SIH) and received conservative management. ⋯ Follow-up magnetic resonance imaging (MRI) showed the disappearance of abnormal radiological features associated with intracranial hypotension. She currently remains symptom free for 9 months. Delivery of autologous blood patch via a cervical epidural Racz catheter inserted from the upper thoracic spine can be a safe and effective method for patients with SIH due to cerebrospinal fluid (CSF) leakage in the upper cervical spine.
