Lumbar intraspinal synovial cyst (LISC) refers to a cyst that arises from the zygapophyseal joint capsule of the lumbar spine and contains serous or gelatinous fluid. In cases of LISCs resistant to conservative treatments, various minimally invasive percutaneous spinal techniques (MIPSTs) may be applied prior to open surgery. ⋯ Conservative treatment, endoscopic surgical procedures, facet joint, intraarticular injection, minimally invasive surgical procedures, needle biopsy, nerve root compression, radiculopathy, synovial cysts.

Clinical Trial
A Prospective, Randomized Cross-Over Trial of T2 Paravertebral Block as a Sympathetic Block in Complex Regional Pain Syndrome.
Sympathetic block is commonly performed in clinical practice for management of intractable pain conditions. However, stellate ganglion block (SGB) alone often does not achieve sufficient sympatholysis of the upper extremity. The paravertebral space continues up to the cervical sympathetic chain and includes the stellate ganglion. We compared the sympatholytic and analgesic effect of paravertebral block performed at the T2 level (T2 PVB) with that of SGB in patients with complex regional pain syndrome (CRPS) of the upper extremity. ⋯ Sympathetic block, Complex Regional Pain Syndrome, paravertebral block, stellate ganglion block.

Head and facial pain is a common and often difficult to treat disorder. Routine treatments sometimes fail to provide acceptable relief, leaving the patient searching for something else, including narcotics and surgery. Recently, neuromodulation has been expanding to provide another option. Secondary to its potentially temporary nature and relatively manageable risk profile, several reviews have suggested trialing neuromodulation prior to starting narcotics or invasive permanent surgeries. There is evidence that neuromodulation can make a difference in those patients with intractable severe craniofacial pain. ⋯ Neuromodulation, headache, facial pain, craniofacial pain, migraine, cluster headache, trigeminal neuralgia, occipital neuralgia, peripheral nerve stimulator, high cervical spinal cord stimulator, peripheral nerve field stimulator.

The spine is the most common site of skeletal metastatic disease. Vertebral body metastases (VBM) can cause crippling pain, fractures, and spinal cord compression. Radiofrequency ablation (RFA) is a minimally invasive technique that has proven to be a safe method of targeted tissue destruction. Studies have shown that RFA combined with cement vertebral augmentation is safe and effective and has been associated with significant improvements in pain and quality of life. ⋯ Cancer, cancer pain, spinal metastasis, radiofrequency ablation, tumor ablation, cement augmentation.

Observational Study
Depression Trends in Patients with Chronic Pain: An Analysis of the Nationwide Inpatient Sample.
Chronic pain remains a major public health issue that affects the lives of many worldwide, including patients with chronic pain. Comorbidities like depression have been associated with decreased quality of sleep, decreased enjoyment of life activities, increased anxiety, and decreased efficacy in treatments among patients with chronic pain. Despite these associations, the trends and demographic characteristics of patients with chronic pain with depression is yet to be investigated. ⋯ Chronic pain, depression, National Inpatient Sample.
