When is pneumonia not pneumonia: a clinicopathologic study of the utility of lung tissue biopsies in determining the suitability of cadaveric tissue for donation.

Healthcare-associated pneumonia (HCAP) represents a major diagnostic challenge because of the relatively low sensitivity and specificity of clinical criteria, radiological findings, and microbiologic culture results. It is often difficult to distinguish between pneumonia, underlying pulmonary disease, or conditions with pulmonary complications; this is compounded by the often-subjective clinical diagnosis of pneumonia. We conducted this study to determine the utility of post-mortem lung biopsies for diagnosing pneumonia in tissue donors diagnosed with pneumonia prior to death. Subjects were deceased patients who had been hospitalized at death and diagnosed with pneumonia. Post-mortem lung biopsies were obtained from the anatomic portion of the cadaveric lung corresponding to chest radiograph abnormalities. Specimens were fixed, stained with hematoxylin and eosin, and read by a single board-certified pathologist. Histological criteria for acute pneumonia included intense neutrophilic infiltration, fibrinous exudates, cellular debris, necrosis, or bacteria in the interstitium and intra-alveolar spaces. Of 143 subjects with a diagnosis of pneumonia at time of death, 14 (9.8 %) had histological evidence consistent with acute pneumonia. The most common histological diagnoses were emphysema (53 %), interstitial fibrosis (40 %), chronic atelectasis (36 %), acute and chronic passive congestion consistent with underlying cardiomyopathy (25 %), fibro-bullous disease (12 %), and acute bronchitis (11 %). HCAP represents a major diagnostic challenge because of the relatively low sensitivity and specificity of clinical criteria, radiological findings, and microbiologic testing. We found that attending physician-diagnosed pneumonia did not correlate with post-mortem pathological diagnosis. We conclude that histological examination of cadaveric lung tissue biopsies enables ascertainment or rule out of underlying pneumonia and prevents erroneous donor deferrals.

Unmet need in Behcet's disease: most patients in routine follow-up continue to have oral ulcers.

The clinical course of Behcet's disease (BD) as a multisystemic disorder with a remitting-relapsing nature is insufficiently explored. As complete remission should be aimed in all inflammatory diseases, we investigated the frequency of complete remission in patients with BD followed in long-term, routine practice. In this retrospective study, 258 patients with BD who were regularly followed in outpatient clinics were assessed. The demographic and clinical data for active organ manifestations and treatment protocols were evaluated, and "complete remission" for this study was defined as no sign of any disease manifestation in the current visit and the preceding month. Two hundred fifty-eight patients with BD (F/M 130/128, mean age 41.1 ± 11.5 years) were included to the study. Mucocutaneous disease was present in 48.4 % (n = 125). Mean visit number was 6.8 ± 2.7, and mean follow-up duration was 45.8 ± 36.5 months. Patients were clinically active in 67.2 % (n = 1,182) of the total visits (n = 1,757), which increased to 75.6 % (68.1-90.3) when the month preceding the visit was also included. The most common active manifestation was oral ulcers (39.4-63.2 %) followed by other mucocutaneous manifestations and musculoskeletal involvement. When multivariate analysis was performed, oral ulcers, which are the main cause of the clinical activity, negatively correlated with immunosuppressive treatments (ß = -0.356, p < 0.000) and age (ß = -0.183, p = 0.04). It is fairly difficult to achieve complete remission in BD with current therapeutic regimens. The reluctance of the clinician to be aggressive for some BD manifestations with low morbidity, such as mucocutaneous lesions and arthritis, might be influencing the continuous, low-disease activity state, especially due to oral ulcers, in BD patients.

What we don't know may hurt us: urinary drainage system tubing coils and CA-UTIs-A prospective quality study.

Catheter-associated urinary tract infections account for >30% of infections in acute care hospitals. We hypothesized that coiling of/kinks in the indwelling urinary bladder catheter (IUBC) drainage bag tubing would increase the occurrence of infection/bacteriuria. Ninety-one patient events were evaluated over 60 days. All outcome variables trended with greater frequency among those with a coil in the IUBC tubing; only fever (temperature > 38.1°C) correlated significantly between groups (P = .003). If IUBC is unavoidable, strategies such as keeping collection bag below the level of bladder and avoiding any coiling in the drainage system should be employed. Further study of these phenomena is needed.

Decreasing ventricular infections through the use of a ventriculostomy placement bundle: experience at a single institution.

OBJECT: Ventricular infection after ventriculostomy placement carries a high mortality rate. Responding to ventriculostomy infection rates, a multidisciplinary performance improvement team was formed, a comprehensive protocol for ventriculostomy placement was developed, and the efficacy was evaluated. METHODS: A best-practice protocol was developed, including hand hygiene before the procedure; prophylactic antibiotics; sterile gloves changed between preparation, draping, and procedure; hair removal by clipping for dressing adherence; skin preparation using iodine povacrylex (0.7% available iodine) and isopropyl alcohol (74%); full body and head drape; full surgical attire for the surgeon and other bedside providers; and an antimicrobial-impregnated catheter. A checklist of critical components was used to confirm proper insertion and to monitor practice. Procedure-specific infection rates were calculated using the number of infections divided by the number of patients in whom an external ventricular drainage (EVD) device was inserted × 100 (%). Data were reported back to providers and to the committee. Bundle compliance was monitored over a 4-year period. RESULTS: At the authors' institution, 2928 ventriculostomies were performed between the beginning of the fourth quarter of 2006 and the end of the first quarter of 2012. Although the best-evidence bundle was applied to all patients, only 588 (20.1%) were checklist monitored (increasing from 7% to 23% over the study period). The infection rate for the 2 quarters before bundle implementation was 9.2%. During the study period, the rate decreased quarterly to 2.6% and then to 0%. Over a 4-year period, the rate was 1.06% (2007), 0.66% (2008), 0.15% (2009), and 0.34% (2010); it was 0% in 2011 and the first quarter of 2012. The overall EVD infection rate was 0.46% after bundle implementation. CONCLUSIONS: Bundle implementation including an antimicrobial-impregnated catheter dramatically decreased EVD-related infections. Training and situational awareness of appropriate practice, assisted by the checklist, plus use of the antibiotic-impregnated catheter resulted in sustained reduction in ventriculitis.
