Pain about the bridge of the nose is often a diagnostic dilemma. There is an important recognizable subgroup who may, as a consequence of involvement of the external nasal nerve in nasal injury, exhibit neuralgic pain after a latent interval. Temporary relief by anaesthesia can be achieved and cure is possible by division of the anterior ethmoidal nerve. This rare cause of facial pain is presented using two illustrative cases.

Chronic somatic pain patients often present more than one pain location with concomitant different pain complaints (pain qualities) which may need to be treated individually. Major attention should be given to the identification of opioid insensitive neurogenic pain qualities, and to a lesser degree the pain intensity. ⋯ Other special pain qualities should be treated as specifically as possible. With this differentiated pharmacological therapy approximately 70-90% of somatic pain patients can be treated with satisfactory pain relief or freedom from pain, at least at rest.

The purpose of this study was to describe family factors which influence cancer pain. Previous research has focused on the patients' and professional caregivers' perspective of pain. ⋯ Findings of the study demonstrate family perceptions of pain, caregiver burden associated with pain, caregiver moods and differences in caregiver experiences of pain between three sites of care including a hospice, a community hospital and a cancer centre. Understanding the perspective of the family caregivers and their role in pain management can assist health care providers in management of the patient's pain.

The well established use of oral morphine in the treatment of chronic cancer pain has developed empirically and a knowledge of its pharmacokinetics is not necessary in order to use the drug effectively. However recent information about the pharmacokinetics of morphine may help resolve the controversy about oral to parenteral relative potency ratios, and may also in the future shed some light on the problem of patients whose pain does not respond to morphine.

Metabolic acidosis and hyperlactataemia are important, independent findings in acute illness, and the combination of these abnormalities carries a grave prognosis. Despite this there is still controversy about the most appropriate therapy of lactic acidosis, and the relationship of commonly used acid base measurements to blood lactate levels. This paper details studies in shock and multiple organ failure examining these issues. ⋯ Serious acid base derangements were not seen. Significant hyperlactataemia was present throughout haemofiltration as a result of the infusion of replacement fluid containing 45 mmol/l lactate. The only alterations in acid base status were transient falls in arterial bicarbonate and base excess at one hour.
