A 21-year-old man suffered from diffuse low back pain and sciatica for 10-s periods once or twice a day over a period of 6 months. After this, pain became chronic and was resistant to conventional conservative treatment. Only acetylsalicylic acid diminished pain. ⋯ The time between onset of symptoms and final diagnosis was 18 months. Symptoms disappeared after surgery. Clinical and radiological aspects of the case are discussed.

We report a case of severe respiratory depression during postoperative patient-controlled analgesia (PCA) in a 14-year-old boy. The medication cassette of a Pharmacia CADD-PCA 5200 was not properly connected, which led to a free-flow infusion of about 85 mg piritramide (strong mu-opioid agonist) within 15 min; the patient lost consciousness and developed apnea. He was successfully treated with artificial ventilation via ambu-bag and 0.2 mg naloxone i. v. The incident occurred approx. 2 h after the start of postoperative medication, when other infusions (suspended above the PCA device level) had been stopped, making the free-flow opioid infusion possible. As the PCA device was in a bedside pump enclosure, the disconnection was not immediately apparent. ⋯ Although PCA is considered a safe method, it can have potentially lethal complications: Technical problems or serious handling errors involve the risk of large volumes of analgesics being infused within a very short time. Therefore, we recommend apparative monitoring (e. g., pulse oximetry) as a necessary condition for the safe use of PCA.

Undertreatment of cancer pain is a well-known and worldwide problem. Every country has its specific restrictions. In Germany studies have referred undertreatment to pain states and therapeutic aspects in transverse inquiries, and others to 6-month records of regional prescription data. This study adds some long-term (3 years) information about doctors' (330 general practitioners throughout Germany) prescribing habits concerning strong opioids. ⋯ We urgently need more information on the underlying reasons for the undertreatment of cancer pain. The data presented so far make it possible to draw up guidelines and a graduated education programme for patients and health care professionals.
