Chronic female pelvic pain--part 1: clinical pathoanatomy and examination of the pelvic region.
Chronic pelvic pain is defined as the presence of pain in the pelvic girdle region for over a 6-month period and can arise from the gynecologic, urologic, gastrointestinal, and musculoskeletal systems. As 15% of women experience pelvic pain at some time in their lives with yearly direct medical costs estimated at $2.8 billion, effective evaluation and management strategies of this condition are necessary. ⋯ The challenge of accurately diagnosing chronic pelvic pain resides in the degree of peripheral and central sensitization of the nervous system associated with the chronicity of the symptoms, as well as the potential influence of the affective and biopsychosocial factors on symptom development as persistence. Once the musculoskeletal origin of the symptoms is identified, a clinical examination schema that is based on the location of primary onset of symptoms (lumbosacral, coccygeal, sacroiliac, pelvic floor, groin or abdominal region) can be followed to establish a basis for managing the specific pain generator(s) and manage tissue dysfunction.

We report the successful use of low-dose ketamine infusion for treating a severe episode of painful myoclonus in the lower extremities, associated with opioid-induced hyperalgesia (OIH), in a patient who was receiving long-term, high dose intrathecal hydromorphone therapy. A low-dose ketamine infusion immediately relieved the painful myoclonus. It also enabled a reduction in the intrathecal opioid dosage leading to a resolution of the acute symptoms attributed to OIH.
