Epidural infection represents a serious albeit infrequent complication of long-term epidural catheterization. The catheter hub is regarded as the main point of entry for microorganisms among the three possible routes (hematogenous, insertion site, hub) of microbial colonization of the inserted catheter. The current study was aimed at evaluating whether frequent changing of antimicrobial filters carries an increased risk of catheter hub contamination and the time-dependent efficacy of commonly used antimicrobial filters after prolonged use. ⋯ Our data indicate significant correlation between the incidence of catheter hub colonization and the filter-change frequency, when the skin close to the filter-hub connection is contaminated. Our results also show that Portex and Sterifix-Braun bacterial filters, when perfused with reduced volumes at low injection pressures, maintain an unmodified antimicrobial function for at least 60 days. Based on these data, it appears clinically feasible to reduce the frequency of filter changes during long-term epidural catheterization, with a consequent possible decrease of epidural catheter colonization.

Complications of intrathecal opioids and bupivacaine in the treatment of "refractory" cancer pain.
To test the concept that externalized tunneled intrathecal catheters lead to a high risk of complications, such as meningitis and epidural abscess, and therefore should not be used for durations of intrathecal pain treatment of > 1 week. ⋯ In our population and with the technique of insertion and care reported here, the use of externalized tunneled intrathecal catheters has not been associated with higher rates of complications when compared with earlier reported rates of externalized epidural catheters and internalized (both epidural and intrathecal) catheters connected to subcutaneously implanted ports, reservoirs, and pumps. The opinion that the use of externalized tunneled intrathecal catheters should be restricted only to patients who need pain treatment for < 1 week (because of the potential risk of infection, particularly meningitis and epidural abscess) is unfounded.

The treatment of patients with chronic unilateral or bilateral orchialgia, defined as intermittent or constant testicular pain of greater than 3 months and of unclear cause, is difficult. This pain significantly interferes with the daily activities of the patient. We have seen 12 patients with chronic orchialgia of unknown etiology and each had a normal history, physical examination and normal scrotal sonogram. ⋯ Two patients had bilateral transrectal injections of local anesthetic (5 ml bupivacaine) and methylprednisolone into the region of the pelvic plexus under transrectal ultrasound guidance. They were successfully treated with this injection technique. On the basis of our results, we recommend transrectal blockade of nerves from the pelvic plexus or inguinal orchiectomy as the procedure of choice for patients in whom medical treatment fails.

Randomized Controlled Trial Clinical Trial
Cost-effectiveness of palliative chemotherapy in advanced gastrointestinal cancer.
Chemotherapy may relieve tumor-related symptoms, may improve quality of life and prolong survival in advanced gastrointestinal cancer. The extent of such improvements is unclear despite the extensive use of this treatment modality, and there are no studies concerning the economic cost of any gain achieved in the quantity and quality of life by chemotherapy. ⋯ The results of this study suggest that palliative chemotherapy is cost-effective in patients with advanced gastric and colorectal cancer. Knowledge about survival and quality of life benefits is still limited in patients suffering from gastric and pancreatic-biliary cancer.
