Cytomegalovirus (CMV) is an opportunistic pathogen that exacerbates inflammatory bowel disease (IBD). There are no clear diagnostic criteria for CMV infection in IBD patients. The aim of this study was to evaluate the importance of the diagnosis of CMV infection with CMV-DNA polymerase chain reaction (PCR) in the colonic mucosa and the response to antiviral treatment. We retrospectively analyzed the clinical data of 30 patients with IBD (24 men, 6 women; median age: 42 years) who were hospitalized because of IBD exacerbation and whose samples were assessed by tissue CMV-DNA PCR positivity. Most of the IBD patients had ulcerative colitis (90%). The CMV-DNA PCR median value was 8848 copies/mL of tissue (range 90–242,936 copies/mL). Blood CMV-DNA PCR was found to be positive in a small group (33.3%, 10/30) of tissue CMV-DNA PCR-positive cases. immunohistochemistry tests were positive in only 5 of the 23 patients positive for CMV-DNA PCR in the colonic mucosa, and high remission (25/30, 83.3%) was detected with antiviral therapy. Recurrence of CMV colitis infection was observed in 9 of 25 patients who had remission with antiviral therapy. The tissue CMV-DNA PCR test was found to be more useful than blood CMV-DNA PCR and immunohistochemistry tests for diagnosing CMV colitis, and the tissue CMV-DNA PCR test enabled rapid and appropriate treatment.

Crit Care 1999, 3 3 ( (s su up pp pl l 1 1) ):P1 I In nt tr ro od du uc ct ti io on n: : Critically ill patients requiring intensive care are at risk of iatrogenic ocular damage. Studies have reported an incidence of eye problems of up to 40% in critically ill ventilated patients. We conducted this study to assess the incidence of ocular complications in our intensive care unit where all patients are cared for according to an eye care standard.M Me et th ho od ds s: : All ventilated patients over a 2 month period were included. Ophthalmic assessment was performed on admission and repeated every other day during the period of ventilation. At each assessment the average Ramsey sedation score over the previous 24 h, the presence of tracheal secretions and the presence of ventilation associated pneumonia was noted. Eye care performed was recorded. R Re es su ul lt ts s: : Sixty patients were included. One patient developed corneal exposure keratopathy. No patient developed conjunctivitis or corneal ulceration. Further advice on appropriate measures of eye care was given in five cases (8%). Nine patients (15%) had large amounts of respiratory secretions with positive microbiological results.C Co on nc cl lu us si io on n: : This study confirms that the use of an eye care standard is associated with a low incidence of ocular surface complications. The incidence of ocular complications in this group of patients is far lower than previously described.

Florence Nightingale defined the concept of noise as a cruel situation that can harm both sick and healthy people. 1 Due to the high number of technical devices in intensive care units (ICUs), the level of noise generated by such devices is inevitably high. Noise resulting from the operating and alarms of monitors, infusion and feeding pumps, and mechanical ventilators, which occupy a vital place in patient
