Guillain-Barre syndrome (GBS) is an acute disease characterised by symmetrical muscle weakness, loss of sensation and reflex. There is usually a viral infection at the beginning of the disease. Here, we report a GBS case which did not respond to any treatment strategy at first and was diagnosed as Human Immunodeficiency Virus positive (HIV+) during the search for the aetiology. A 32-year-old male patient who presented to a medical centre with symptoms of gait disturbance and arm and leg numbness was found to have albuminocytologic dissociation upon cerebrospinal fluid examination. After the diagnosis of GBS, immunoglobulin G (IVIG) therapy (400 mg kg(-1) day(-1) 5 days) was started as a standard therapy. This therapy was repeated due to a lack of improvement of symptoms. During this therapy, the patient was sent to our clinic with symptoms of respiratory failure and tetraplegia. He was conscious, cooperative, haemodynamically stable and his arterial blood gas analyses were: pH: 7.28, PaO2: 74.4 mmHg, PCO2: 63.8 mmHg. He was intubated, mechanically ventilated and underwent plasmapheresis. After the investigation of aetiology, HIV(+), CD4/CD8: 0.17, absolute CD4: 71 cells mL(-1) were detected and antiretroviral therapy was started. The patient died from multiple organ failure due to sepsis on day 35. In conclusion, HIV infection should be kept in mind in GBS patients, especially those not responding to routine treatment. As a result, not only could the patient receive early and adequate treatment, but also HIV infection transmission would be avoided.

This study was conducted to evaluate the impact of central venous catheters impregnated with chlorhexidine and silver sulphadiazine on the incidence of colonization and catheter-related bloodstream infection in critically ill patients. One hundred and thirty-three patients requiring central venous catheterization were chosen at random to receive either an antiseptic-impregnated triple-lumen catheter (N = 64) or a standard triple-lumen catheter (N = 69). The mean (SD) durations of catheterization for the antiseptic and standard catheters were 11.7 (5.8) days (median 10; range 3-29) and 8.9 (4.6) days (median 8.0; range 3-20), respectively (P = 0.006). Fourteen (21.9%) of the antiseptic catheters and 14 (20.3%) of the standard catheters had been colonized at the time of removal. (P = 0.834). Four cases (6.3%) of catheter-related bloodstream infection were associated with antiseptic catheters and one case (1.4%) was associated with a standard catheter (P = 0.195). The catheter colonization rates were 18.7/1000 catheter-days for the antiseptic catheter group and 22.6/1000 catheter-days for the standard catheter group (P = 0.640). The catheter-related bloodstream infection rates were 5.3/1000 catheter-days for the antiseptic catheter group and 1.6/1000 catheter-days for the standard catheter group (P = 0.452). In conclusion, our results indicate that the use of antiseptic-impregnated central venous catheters has no effect on the incidence of either catheter colonization or catheter-related bloodstream infection in critically ill patients.

PCT is frequently used in ICU patients. Recent studies suggest that the use of a LMA has achieved good control of airway during PCT [1]. The COPA is a modification of the Guedel airway which allows manual ventilation by directly connecting to the breathing system [2]. We designed a prospective randomized study to compare the COPA and LMA devices during PCT in ICU patients.
