Case ReportsMethadone as a rescue for failed high-dose opiate therapy for catastrophic pain.
Methadone is a unique opioid with several special properties besides being a mu agonist, which makes for difficulty in the calculation of equianalgesic doses. A series of three cases is presented to illustrate this point.

Clinical TrialEfficacy of treatment to relieve mucositis-induced discomfort.
To determine the efficacy of a mouthwash in relieving mucositis-induced discomfort in patients receiving chemotherapy, 31 (16 male, 15 female) with a mean age of 45 (range 16-80) were given an in-house three-drug (lidocaine, diphenhydramine and sodium bicarbonate in normal saline) mouthwash when they developed mucositis of any severity. The complications were assessed on the CALGB (Cancer and Leukemia Group B) scale. The response to the mouthwash was reported on a self-assessment scale. ⋯ The mean mucositis severity score was 1.9 (range 1-4), and the average self-assessment (response) score was 0.81 (range 0-2). The mean mucositis score during the worst stage of mucositis was 2.25 (range 1-4), and the average self-assessment (response) score during the worst stage of mucositis was 0.91 (range 0-2.7). These results suggests that this three-drug mouthwash provides effective symptomatic relief in patients with chemotherapy-induced mucositis.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialA double-blind, randomised, parallel study comparing intravenous dolasetron plus dexamethasone and intravenous dolasetron alone for the management of fractionated cisplatin-related nausea and vomiting.
Fractionated cisplatin-containing regimens are routinely used for chemotherapy in certain types of cancer. Dolasetron has been shown to be effective in preventing acute emesis related to high-dose cisplatin chemotherapy over 24 h; its effectiveness has not been evaluated in fractionated cisplatin-containing chemotherapy. This trial was designed to assess the efficacy of dolasetron alone or dolasetron plus dexamethasone in preventing nausea and vomiting related to fractionated cisplatin chemotherapy. ⋯ Both treatments were administered safely. As seen with other 5-HT3 receptor antagonist antiemetics, the addition of dexamethasone to dolasetron significantly increases effectiveness in preventing nausea and vomiting related to fractionated cisplatin chemotherapy. Both dolasetron and dolasetron plus dexamethasone were well tolerated.

Clinical TrialControl of high-dose-cisplatin-induced emesis with an all-oral three-drug antiemetic regimen.
In this pilot trial, the antiemetic efficacy and tolerability of an all-oral antiemetic combination in the prevention of both acute and delayed nausea and vomiting following high-dose cisplatin was evaluated. Fifty-two patients receiving cisplatin (median dose 100 mg/m2) were entered. Patients received (1) 60 min prior to cisplatin: prochlorperazine spansule 15 mg, dexamethasone 20 mg, granisetron 2 mg; (2) 12 h after cisplatin: prochlorperazine spansule 15 mg, dexamethasone 10 mg; (3) on days 2 and 3: prochlorperazine spansule 15 mg b.i.d., dexamethasone 8 mg b.i.d.; (4) on days 4 and 5: dexamethasone 4 mg b.i.d. ⋯ Treatment was well tolerated with infrequent and minor adverse events. In conclusion, an all-oral combination of granisetron, dexamethasone and prochlorperazine is a highly effective and well-tolerated regimen for preventing acute cisplatin-induced emesis. Control of delayed emesis was not better than with current standard treatment, and more effective approaches are needed.

ReviewIntravascular catheters impregnated with antimicrobial agents: a milestone in the prevention of bloodstream infections.
Vascular catheters impregnated with antimicrobial agents have been shown to decrease the risk of catheter-related colonization and bloodstream infections. Various antimicrobials and antiseptics have been used. In a recent meta-analysis of 12 studies, catheters coated with chlorhexidine and silver sulfadiazine (CH/SS) were shown to be significantly less likely to be associated with catheter-related bloodstream infections than uncoated catheters. ⋯ The M/R catheters are coated on the external and internal surfaces and have an antimicrobial durability of 4 weeks. Although no resistance to either minocycline or rifampin has been seen in two trials, further studies are required to determine whether the risk of resistance outweighs the benefits derived from their use. In conclusion, antimicrobial catheters have been shown to be highly cost effective in decreasing the risk of catheter-related bloodstream infection.
