Pelvic pain is a common condition. Treatment interventions have traditionally targeted biomedical conditions with variable success. ⋯ The following description of gynecologic, urologic, gastrointestinal, musculoskeletal, and neurologic conditions that can cause or are associated with chronic pelvic pain leads to conservative management proposals based on the available evidence. Finally, nonoperative interventional strategies are described, which target the pain system from a cognitive behavioral perspective, address movement dysfunctions, and address interventional pain technique possibilities.

Review Case Reports
High doses of topical amitriptyline in neuropathic pain: two cases and literature review.
Severe chronic neuropathic pain is a challenge to treat, and due to adverse effects of classical oral medication, optimal and effective dose levels are difficult to reach. Therefore, administration of topical analgesics might be an option, due to reduced adverse effects, and increased patient compliance. The aim of this article is to describe two cases treated effectively with topical amitriptyline 5% and 10%, the highest dosage described to date. ⋯ The patient decided to stop topical treatment because of these adverse effects. These two cases suggest an analgesic dose-response effect of topical amitriptyline in painful neuropathy. Systemic adverse effects should be taken into account.

Randomized Controlled Trial
Analgesic effectiveness of dipyrone (metamizol) for postoperative pain after herniorrhaphy: a randomized, double-blind, dose-response study.
The efficacy of non-narcotic analgesics is mostly supported by randomized, placebo-controlled trials with no comparison with ordinary practice. Additionally, systematic reviews of these placebo-controlled trials have failed to determine clinically meaningful dose-response effect. ⋯ This trial shows a dose-response effect of 40 mg/kg over 15 mg/kg of intravenous dipyrone based on better movement-induced pain control, lower morphine consumption and fewer opioid-related side effects.

Good surgical outcomes depend in part on good pain relief, allowing for early mobilization, optimal recovery, and patient satisfaction. Postsurgical pain has multiple mechanisms, and multimechanistic approaches to postoperative analgesia are recommended and may be associated with improved pain relief, lowered opioid doses, and sometimes a lower rate of opioid-associated side effects. Acetaminophen (paracetamol) is a familiar agent for treating many types of pain, including postsurgical pain. ⋯ Intravenous (IV) acetaminophen and an opioid analgesic administered in the perioperative period may be followed by an oral acetaminophen and opioid combination in the postoperative period. Transitioning from an IV acetaminophen and opioid formulation to a similar but oral formulation of the same drugs appears to be a reasonable step in that both analgesic therapies are known to be safe and effective. For postsurgical analgesia with any acetaminophen product, patient education is necessary to be sure that the patient does not concurrently take any over-the-counter products containing acetaminophen and accidentally exceed dose limits.
