Randomized Controlled Trial Clinical TrialThe effects of urokinase instillation therapy via percutaneous transthoracic catheter in loculated tuberculous pleural effusion: a randomized prospective study.
The purpose of this study was to propose that intrapleural urokinase (UK) instillation could reduce pleural thickening in the treatment of loculated tuberculous pleural effusion. Forty- three patients who were initially diagnosed as having loculated tuberculous pleural effusion were assigned at random to receive either the combined treatment of UK instillation including anti-tuberculosis agents (UK group, 21 patients) or strictly the unaccompanied anti-tuberculous agents (control group, 22 patients). The UK group received 100,000 IU of UK dissolved in 150 ml of normal saline daily, introduced into the pleural cavity via a pig-tail catheter. ⋯ The interval of symptoms observed prior to treatment of patients with RPT > or = 10 mm (6.0 +/- 3.4 wks) was detected to be significantly longer than in those with RPT < 10 mm (2.1 +/- 1.2 wks) in the control group (p < 0.05). However, there were no discernible differences were seen in the pleural fluid parameter in patients with RPT > or = 10 mm, as compared to patients with RPT < 10 mm in the UK group. These results indicate that the treatment of loculated tuberculous pleural effusion with UK instillation via percutaneous transthoracic catheter can cause a successful reduction in pleural thickening.

ReviewTelemedicine in the USA with focus on clinical applications and issues.
Telemedicine usually refers to the use of information-based technologies, such as, computer and communications systems, to provide healthcare across geographic distances. Although telemedicine has the potential to improve healthcare, the number of clinical applications is still small and constrained by custom, regulatory, reimbursement and technical issues. ⋯ Current telemedicine issues in clinics and technological problems to be decided, improved, and challenged, are reviewed. This is followed by conclusions.

Increasing prevalence of vancomycin-resistant enterococci, and cefoxitin-, imipenem- and fluoroquinolone-resistant gram-negative bacilli: a KONSAR study in 2002.
Continued antimicrobial resistance surveillance can provide valuable information for the empirical selection of antimicrobial agents for patient treatment, and for resistance control. In this 6th annual study for 2002, the susceptibility data at 39 Korean Nationwide Surveillance of Antimicrobial Resistance (KONSAR) hospitals were analyzed. Resistance rates of S. aureus were 67% to oxacillin, and 58% to clindamycin. ⋯ Ceftazidime- resistant K. pneumoniae decreased slightly, and imipenem- resistant P. aeruginosa and Acinetobacter spp., and vancomycin-resistant E. faecium increased. In conclusion, vancomycin-resistant E. faecium, cefoxitin-resistant E. coli and K. pneumoniae, and imipenem-resistant P. aeruginosa and Acinetobacter spp. increased gradually, and imipenem- resistant E. coli and K. pneumoniae appeared for the first time. Continued surveillance is required to prevent further spread of these serious resistances.

Case ReportsManagement of detachment of pilot balloon during intraoral repositioning of the submental endotracheal tube.
Submental endotracheal intubation for surgery was used as an alternative to nasotracheal intubation in patients with craniomaxillofacial injury. Generally extubation was performed in the operation room by pulling the tube through the submental incision site. When extubation is not indicated, intraoral indwelling is preferred to submental intubation. ⋯ At the end of the surgery, we noticed the oropharyngeal edema, and so the submental intubation was converted into a standard orotracheal intubation. During that procedure, the pilot balloon was accidentally detached from the endotracheal tube. The situation was managed by cutting a pilot tube from a new, unused endotracheal tube and connecting it to the intubated tube using a needle connector.

Radiological considerations of posterior cervical lateral mass fixation using plate and screw.
The aim of this study is to determine whether the posterior cervical fusion methods with the plate-screw system applied to the lateral mass of cervical spine are radiologically safe to patients. The lateral cervical X-rays and CT scans were done on 40 normal adults without cervical problem. Based on Roy-Camille and Magerl's method, the theological trajectory of screw was shown on films and the parameters were measured. ⋯ A reduced lateral angle of screw (19.6 +/- 3.5 degrees C) performed with the concept based on Magerl's method resulted a longer depth of screw (13.5 +/- 2.1 mm). Both Roy-Camille and Magerl's methods seemed to be radiologically safe to normal persons. However, the authors recommend the reduced lateral angle (19.6 +/- 3.5 degrees C) of screw based on the Magerl's method more than an original Magerl's methods.
