Routine culture for Mycobacterium tuberculosis from bronchoscopy in Taiwan

RESPIROLOGY, Issue 3 2007
Chih-Jen YANG
Background and objective: The value of routine culture for mycobacterium from bronchoscopic washings and the cost-effectiveness is still uncertain in countries where tuberculosis is endemic. This study examined the epidemiology of positive cultures for M. tuberculosis obtained by bronchoscopy to determine the health benefit and cost of a policy of routine culture and smear. Methods: All positive cultures for Mycobacterium tuberculosis in bronchial washings and the corresponding CXR features were analysed. Results: The incidence of tuberculosis in routine bronchoscopy was 3.71%, and in patients who presented with typical tuberculosis features on CXR was 6.5%. Up to 10.6% of culture-proven pulmonary tuberculosis relied on bronchoscopy for diagnosis. The total cost of routine mycobacterium culture and acid-fast bacillus smear during the 2-year period was approximately USD 24 800. Conclusion: Routine mycobacterium culture and acid-fast staining from bronchoscopic specimens appears to be valuable in countries where tuberculosis is prevalent. [source]

SURGICAL SITE MARKING DOES NOT AFFECT STERILITY

ANZ JOURNAL OF SURGERY, Issue 8 2008
John Rooney
Background: In 2005, surgical site marking became mandatory in Australia, with the introduction of the first Australian guidelines to prevent wrong site surgery. It has been our experience that most surgical site marking occurs with the use of a non-sterile marking pen, which has been used on multiple patients and there is little information in the published work about the effects of surgical site marking carried out in this fashion. Our aim was to determine whether the sterility of a surgical site was affected by surgical site marking with a non-sterile surgical marking pen. Methods: Both forearms of 20 volunteers would simulate surgical sites. Surgical site marking was carried out on right forearms with the same non-sterile surgical marking pen, whereas left forearms were unmarked controls. Microbiology swabs were taken from both forearms before, and after, skin sterilization with 10% povidone,iodine. Routine cultures were carried out on the swabs after sodium thiosulphate was used to deactivate residual iodine. Cultures were assessed for growth after 5 days. Results: One of the 20 marked forearms and 15 of the 20 unmarked forearms had bacterial growth on cultures before skin sterilization (P < 0.1). After sterilization with iodine, no bacterial growth occurred in the cultures of the swabs taken from the marked or control arms. Conclusion: Surgical site marking carried out with a non-sterile surgical marking pen did not contaminate the surgical site. We recommend the practice of surgical site marking. [source]

Clinical implication of routine bacterial culture from epidural catheter tips in postoperative cancer patients: a prospective study

ANAESTHESIA, Issue 9 2006
S. Mishra
Summary We conducted a prospective study to determine the epidural tip culture pattern and its clinical implication in postoperative cancer patients. All patients scheduled to undergo various cancer surgeries requiring epidural analgesia were included. Epidural catheter tips were sent for culture on removal. Of the 466 epidural catheter tips sent for culture, 27 showed a positive culture (5.7%). The commonest organism identified was Staphylococcus aureus. There were no signs of local or epidural space infection in any of the patients. The rates of epidural catheter tip cultures in cancer patients are comparable to those in the general patients and the presence of a positive tip culture is not a predictor of epidural space infection. Hence, we recommend that even in cancer patients, routine culture of epidural catheters is not advisable, provided strict asepsis is maintained at the time of insertion, and patients are constantly monitored for early signs of epidural infection.
