Lidocaine suppositories for prostate biopsy.

OBJECTIVES: To evaluate, in a randomized prospective study, the efficiency of transrectal lidocaine suppositories to reduce pain during transrectal prostate biopsy, as suppositories allow longer for the agent to be effective. PATIENTS AND METHODS: In all, 100 patients were randomized to receive either a placebo suppository or 10 mL of 2% (200 mg) lidocaine gel rectally 10 min before biopsy, or a suppository containing 60 mg lidocaine 1 or 2 h before biopsy. Costs (in euros) per application were 0.82 for gel and 0.63 for suppositories. In all patients the same 10-core biopsy technique was used. Pain was evaluated using a visual linear pain scale ranging from 0 to 100 points; the patient's side of the scale did not show the number of points. RESULTS: The mean pain scores in the placebo, lidocaine gel, and lidocaine suppositories applied 1 h and 2 h before biopsy were 36.2, 40.9, 29.2 and 21.2, respectively. Thus patients with no anaesthesia reported 25% more pain than those receiving lidocaine suppositories 1 h before and 71% more pain than those receiving lidocaine suppositories 2 h before biopsy (P = 0.002). CONCLUSIONS: Lidocaine suppositories at a lower dose and with longer to take effect can be used to reduce pain significantly more effectively than the commonly used gel. As suppositories are easy to use and cheap, they are recommended in daily routine prostate biopsy.

Rectal hydrocortisone during vomiting in children with adrenal insufficiency.

AIM: To evaluate rectal hydrocortisone as an emergency glucocorticoid replacement therapy in adrenal insufficient children. METHODS: A parental questionnaire evaluated preferred treatment, problems or benefits of i.m. and rectal hydrocortisone, frequency and indications for administration and who administered treatment. Admissions of children with adrenal insufficiency were monitored. RESULTS: There were 39/52 families who responded to the questionnaire. 93% (26/28) preferred rectal hydrocortisone. Parents or children who previously received emergency treatment from a doctor now self-administered rectal hydrocortisone. The cost of suppositories and i.m. hydrocortisone is similar; however, storage of suppositories was inconvenient. One girl presented with pneumonia and collapse despite rectal hydrocortisone and a hydrocortisone level at admission of >2000 nmol/l with normal electrolytes. CONCLUSIONS: Rectal hydrocortisone is an acceptable and safe emergency therapy. We still advise i.m. hydrocortisone if rectal administration is not possible or with suppository extrusion.
