A significant percentage of chronic headache sufferers use excessive quantities of substances for relief. Drug dependency is frequent in these patients. Patients have an impaired lifestyle, sustain organ system damage, may suffer a withdrawal syndrome, and continue to have headaches. ⋯ The mechanism of substance abuse may be related to repeated use of substances that reinforce behavior and stimulate brain reward systems. Treatment includes comprehensive diagnostic workup, withdrawal of the agent, and use of headache preventives. beta-Adrenergic blockers, tricyclic antidepressants, monoamine oxidase (MAO) inhibitors, and nonsteroidal anti-inflammatory agents may be of value. Behavior modification and dietary counseling are also helpful.

An updated review of patient-controlled analgesia (PCA) for acute pain relief in the postoperative period is presented. The technique, becoming more and more popular with patients, surgeons, and nurses, is undergoing numerous clinical trials under a variety of clinical protocols that are currently being reviewed. Benefits found with PCA include the fact that it is individualized therapy, allowing optimum drug titration; it decreases a patient's anxiety in the postoperative period; and it is a safer and more efficient technique of acute pain relief than conventional therapy. ⋯ Contraindications to the technique and most current equipment in use are listed herein. Clinical experience with PCA at Georgetown University Medical Center has provided, as has been the case elsewhere, data showing the superiority of the technique and its wide acceptance as part of the Acute Pain Service. The anesthesiologist plays a vital role in coordinating the various people and aspects involved in PCA for postoperative pain relief.

The diagnosis and management of various HA syndromes in children and adolescents have been reviewed. The decision as to whether a child's HA is organic or functional may be a difficult one, but a thorough and systematic history and examination coupled with selected laboratory tests will usually guide the examiner to the correct diagnosis.

The recent development of new drug therapies for headache disorders has allowed for the tailoring of treatment to specific patient needs. This paper reviews the pharmacologic management of patients with both headache and concomitant medical illness. The discussion specifically includes the treatment of hypertension, coronary artery disease, mitral valve prolapse, asthma, peptic ulcer disease, obesity, and chronic Epstein-Barr virus infection, occurring concomitantly in patients with headache. Medications that can exacerbate either the headache or concurrent medical condition are noted, and alternative therapies are advised.

Muscle contraction headache is the most common headache afflicting mankind. Acute muscle contraction headache usually presents no problem in treatment and is a self-limited condition. Chronic muscle contraction headache presents a very difficult treatment problem. ⋯ The pathophysiology of muscle contraction headache is unknown. There is much controversy as to whether muscle contraction is the primary cause of this condition or whether muscle contraction is merely another component of this syndrome. The extensive research now going on in the field of chronic pain should help clarify the issue.
