Charlson Index Is Associated with One-year Mortality in Emergency Department Patients with Suspected Infection

Scott B. Murray MD
Abstract Objectives: A patient's baseline health status may affect the ability to survive an acute illness. Emergency medicine research requires tools to adjust for confounders such as comorbid illnesses. The Charlson Comorbidity Index has been validated in many settings but not extensively in the emergency department (ED). The purpose of this study was to examine the utility of the Charlson Index as a predictor of one-year mortality in a population of ED patients with suspected infection. Methods: The comorbid illness components of the Charlson Index were prospectively abstracted from the medical records of adult (age older than 18 years) ED patients at risk for infection (indicated by the clinical decision to obtain a blood culture) and weighted. Charlson scores were grouped into four previously established indices: 0 points (none), 1,2 points (low), 3,4 points (moderate), and ,5 points (high). The primary outcome was one-year mortality assessed using the National Death Index and medical records. Cox proportional-hazards ratios were calculated, adjusting for age, gender, and markers of 28-day in-hospital mortality. Results: Between February 1, 2000, and February 1, 2001, 3,102 unique patients (96% of eligible patients) were enrolled at an urban teaching hospital. Overall one-year mortality was 22% (667/3,102). Mortality rates increased with increasing Charlson scores: none, 7% (95% confidence interval [CI] = 5.4% to 8.5%); low, 22% (95% CI = 19% to 24%); moderate, 31% (95% CI = 27% to 35%); and high, 40% (95% CI = 36% to 44%). Controlling for age, gender, and factors associated with 28-day mortality, and using the "none" group as a reference group, the Charlson Index predicted mortality as follows: low, odds ratio of 2.0; moderate, odds ratio of 2.5; and high, odds ratio of 4.7. Conclusions: This study suggests that the Charlson Index predicts one-year mortality among ED patients with suspected infection. [source]

Laparoscopic management of urachal remnants in adulthood

Background: The aim of this study was to investigate the outcome of laparoscopic excision of urachal remnants (LUR), and to compare the outcome with that of the traditional open excision of urachal remnants (OUR). Methods: Between February 2001 and December 2005, six patients with a mean age of 23.8 years who had a symptomatic urachal sinus underwent radical LUR. Using 12 mm and 5 mm ports, the caudal stump of the urachus was ligated with an absorbable clip and divided. The peritoneal and preperitoneal tissue between the medial umbilical ligaments was dissected free of the transversalis fascia. Dissection was carried out along the preperitoneal plane toward the umbilicus. The cephalic side of the lesion was ligated at the umbilicus with an endo-loop and divided. In addition, four patients who underwent a traditional OUR were included. Peri- and postoperative records were reviewed to assess morbidity, recovery, and outcome. Results: The operative duration was not significantly shorter for the LUR group than the OUR group, but there was generally a reduction in blood loss (mean 16.5 vs 68.3 mL), an earlier resumption of eating (mean 1.3 vs 2.5 days), and a shorter hospital stay (mean 5.3 vs 10.5 days). There were no intraoperative complications in either the LUR or the OUR group. Mean follow up was 5 (range 4,12) months. There were no postoperative complications. Conclusions: The results suggest that LUR can be safely and satisfactorily performed in adulthood. [source]

Providing a Dental Home for Pregnant Women: A Community Program to Address Dental Care Access , A Brief Communication

Peter Milgrom
Abstract Objective: This paper describes a community-based intervention to provide a dental home for women covered by Medicaid in Klamath County, Oregon. In 2001, 8.8 percent of pregnant women served by Medicaid in Oregon received care. The long-term goal of the program is to promote preventive oral care for both mothers and their new infants. Methods: Pregnant women received home/Women, Infant and Children visits and were assigned a dental home under a dental managed care program [Dental Care Organization (DCO)]. All initial care was provided at the Oregon Institute of Technology Dental Hygiene Clinic under the contract with the DCO. Emergency, preventive, and restorative care was provided. Results: Between February 2004 and January 2006, 503 pregnant women were identified; 421 women were contactable. Of these, 339 received home visits (339/421, 80.5 percent) and 235 received care (235/339, 69.3 percent). Overall, 55.8 percent of eligible women received care (235/421). Most who did not have a visit either moved or were not the caretaker of the baby. The missed appointment rate was 9 percent. Conclusion: A community health partnership led to a successful and sustainable model extending care to pregnant women and is being extended to promote preventive care for both new mothers and their offspring.

Efficacy of Spironolactone on Survival in Dogs with Naturally Occurring Mitral Regurgitation Caused by Myxomatous Mitral Valve Disease

F. Bernay
Background: Spironolactone, an aldosterone antagonist, has been demonstrated to decrease mortality in human patients when added to other cardiac therapies. Hypothesis: Spironolactone in addition to conventional therapy increases survival compared with conventional therapy in dogs with naturally occurring myxomatous mitral valve disease (MMVD). Animals: Between February 2003 and March 2005, 221 dogs were recruited in Europe. Nine dogs were excluded from analysis, leaving 212 dogs with moderate to severe mitral regurgitation (MR) caused by MMVD (International Small Animal Cardiac Health Council classification classes II [n = 190] and III [n = 21]). Methods: Double-blinded, field study conducted with dogs randomized to receive either spironolactone (2 mg/kg once a day) or placebo in addition to conventional therapy (angiotensin converting enzyme inhibitor, plus furosemide and digoxin if needed). Primary endpoint was a composite of cardiac-related death, euthanasia, or severe worsening of MR. Results: Primary endpoint reached by 11/102 dogs (10.8%) in the spironolactone group (6 deaths, 5 worsening) versus 28/110 (25.5%) in control group (14 deaths, 8 euthanasia, 6 worsening). Risk of reaching the composite endpoint significantly decreased by 55% (hazard ratio [HR] = 0.45; 95% confidence limits [CL], 0.22,0.90; log rank test, P= .017). Risk of cardiac- related death or euthanasia significantly reduced by 69% (HR = 0.31; 95% CL, 0.13,0.76; P= .0071). Number of dogs not completing the study for cardiac and other miscellaneous reasons similar in spironolactone (67/102) and control groups (66/110). Conclusion and Clinical Importance: Spironolactone added to conventional cardiac therapy decreases the risk of reaching the primary endpoint (ie, cardiac-related death, euthanasia, or severe worsening) in dogs with moderate to severe MR caused by MMVD.

Long-Term Outcomes of CRT-PM Versus CRT-D Recipients

Objective: To compare the rates of all-cause mortality in recipients of cardiac resynchronization therapy devices without (CRT-PM) versus with defibrillator (CRT-D). Methods: Between February 1999 and July 2004, 233 patients (mean age = 69 8 years, 180 men) underwent implantation of CRT-PM or CRT-D devices. New York Heart Association (NYHA) heart failure functional class II was present in 11%, class III in 69%, and class IV in 20% of patients; mean left ventricle ejection fraction (LVEF) was 26.5 6.5 %, 48% presented with idiopathic dilated cardiomyopathy and 49% with ischemic heart disease. Cox multiple variable regression analysis was performed in search of predictors of death. Results: The clinical characteristics of the 117 CRT-PM and 116 CRT-D recipients were similar, except for LVEF (28.2 6.2% vs 25.0 6.5%, respectively; P < 0.001), and ischemic versus nonischemic etiology of heart failure (41% vs 56%, respectively P = 0.02). Over a mean follow-up of 58 15 months, no significance difference in overall mortality rate was observed between the two study groups. Male sex, NYHA functional class IV, and atrial fibrillation at implant were significant predictors of death. Conclusions: There was no difference in long-term survival rate among patients with CRT-D versus CRT-PM, although CRT-D more effectively lowered the sudden death rate. Male sex, NYHA functional class IV, and atrial fibrillation predicted the worst prognosis. [source]

Eui Kyu CHIE
Abstract Aim: To evaluate the outcome of breast-conserving treatment including adjuvant radiotherapy in patients with multifocal or multicentric breast cancers. Methods: Between February 1996 and January 2002 13 patients presented with multifocal or multicentric breast tumors underwent breast-conserving therapy. Their median age was 44 years (range; 32,56). Nine patients had T1 disease and four had T2 disease. Nodal involvement was confirmed in three patients. All patients had breast-conserving surgery and axillary lymph node dissection with clear resection margin. Whole breast irradiation was given up to 50.4 Gy in 28 fractions followed by 10 Gy boost to tumor bed. Twelve patients received adjuvant systemic therapy: chemotherapy in four patients, hormonal therapy in five patients and both in three patients. Results: At a median follow-up duration of 70 months, all patients were alive without evidence of disease. The cosmetic outcome was evaluated in 11 patients. Cosmesis was excellent in two patients, good in six patients and fair in three patients. Conclusion: Multifocal and/or multicentric breast cancers can be successfully treated with breast-conserving surgery and adjuvant radiotherapy when complete microscopic resection and contemporary systemic therapy are given.
