Rationale: Asthma and obesity often occur together in children. It is unknown whether asthma contributes to the childhood obesity epidemic. Objectives: We aimed to investigate the effects of asthma and asthma medication use on the development of childhood obesity. Methods: The primary analysis was conducted among 2,171 nonobese children who were 5-8 years of age at study enrollment in the Southern California Children's Health Study (CHS) and were followed for up to 10 years. A replication analysis was performed in an independent sample of 2,684 CHS children followed from a mean age of 9.7 to 17.8 years. Measurements and Main Results: Height and weight were measured annually to classify children into normal, overweight, and obese categories. Asthma status was ascertained by parent- or self-reported physician-diagnosed asthma. Cox proportional hazards models were fitted to assess associations of asthma history with obesity incidence during follow-up. We found that children with a diagnosis of asthma at cohort entry were at 51% increased risk of developing obesity during childhood and adolescence compared with children without asthma at baseline (hazard ratio, 1.51; 95% confidence interval, 1.08-2.10) after adjusting for confounders. Use of asthma rescue medications at cohort entry reduced the risk of developing obesity (hazard ratio, 0.57; 95% confidence interval, 0.33-0.96). In addition, the significant association between a history of asthma and an increased risk of developing obesity was replicated in an independent CHS sample. Conclusions: Children with asthma may be at higher risk of obesity. Asthma rescue medication use appeared to reduce obesity risk independent of physical activity.

This evidence review aimed to conceptualize patient satisfaction with anesthesia care (PSAC), which has been linked to reimbursement, competency evaluations, and litigation; to describe factors affecting PSAC; and to develop provider recommendations to enhance PSAC. The search for systematic reviews, survey reports, qualitative studies, and consumer satisfaction reports within the last 20 years excluded pediatric and obstetric articles. The search yielded 27 quantitative, 7 qualitative, and 9 consumer satisfaction articles. High levels of PSAC are reported using a variety of methods. Studies evaluating patient perioperative experiences document that fear and anxiety with prior patient experiences have an impact on anticipatory anxiety. Patients reported desiring positive experiences and emotional connections with anesthesia providers. Modifiable dissatisfiers included anxiety, inadequate explanation of anesthesia, postoperative pain and nausea or vomiting, long surgeries or wait times, and anesthesia complications. Besides providing preoperative information with reasonable expectations (eg, for nausea and vomiting) and treating discomfort, anesthetists must engage emotionally with patients. Measures of PSAC should include the emotional component of PSAC. Future research addressing patient experiences with differing anesthesia methods would be helpful for providers trying to understand and facilitate patient coping.

Background: Asthma and rhinitis are common childhood health conditions. Being an understudied and rapidly growing population in the US, Hispanic children have a varying risk for these conditions that may result from sociocultural (including acculturative factors), exposure and genetic diversities. Hispanic populations have varying contributions from European, Amerindian and African ancestries. While previous literature separately reported associations between genetic ancestry and acculturation factors with asthma, whether Amerindian ancestry and acculturative factors have independent associations with development of early-life asthma and rhinitis in Hispanic children remains unknown. We hypothesized that genetic ancestry is an important determinant of early-life asthma and rhinitis occurrence in Hispanic children independent of sociodemographic, acculturation and environmental factors. Methods: Subjects were Hispanic children (5-7 years) who participated in the southern California Children's Health Study. Data from birth certificates and questionnaire provided information on acculturation, sociodemographic and environmental factors. Genetic ancestries (Amerindian, European, African and Asian) were estimated based on 233 ancestry informative markers. Asthma was defined by parental report of doctor-diagnosed asthma. Rhinitis was defined by parental report of a history of chronic sneezing or runny or blocked nose without a cold or flu. Sample sizes were 1,719 and 1,788 for investigating the role of genetic ancestry on asthma and rhinitis, respectively. Results: Children had major contributions from Amerindian and European ancestries. After accounting for potential confounders, per 25% increase in Amerindian ancestry was associated with 17.6% (95% confidence interval [CI]: 0.74-0.99) and 13.6% (95% CI: 0.79-0.98) lower odds of asthma and rhinitis, respectively. Acculturation was not associated with either outcome. Conclusions: Earlier work documented that Hispanic children with significant contribution from African ancestry are at increased asthma risk; however, in Hispanic children who have little contribution from African ancestry, Amerindian ancestry was independently associated with lower odds for development of early-childhood asthma and rhinitis.

In the United States, each year 1% to 2% of deaths are brain deaths. Considerable variation in the practice of determining brain death still remains, despite the publication of practice parameters in 1995 and an evidence-based guideline update in 2010. This review is intended to give bedside clinicians an overview of definition, the causes and pitfalls of misdiagnosing brain death, and a focus on the specifics of the brain death determination process. © SAGE Publications.

Background: The biologic materials currently available for hernia repairs are costly and there are limited statistics on recurrences and rates of infection in connection with their use in complex cases. Methods: We performed a retrospective review and comparison of two types of biologic mesh used at our institution for abdominal hernia repairs spanning a 1-year period. Demographic data and outcomes relating to surgical site infections, hernia recurrences, and mortality were analyzed. Of the 35 patients in the study, 23 patients (Group I) were managed with SurgiMend, a neonatal bovine mesh, and 12 patients (Group II) were managed with Flex HD, a human-derived mesh. Results: The study cohorts met criteria for high-risk stratification based on body mass index, comorbid conditions, and a high prevalence of contaminated wounds. The overall surgical site infection rate was 17 % for Group I and 50 % for Group II. These differences reached statistical significance when comparing superficial infections but not for deep infections with mesh involvement. Hernia recurrences in Group I were 5 % compared to 33 % in Group II. No deaths were observed. Conclusions: These preliminary data demonstrate promising short-term outcomes for high-risk complex hernias repaired with biologic mesh, particularly SurgiMend, but the long-term durability of these biological materials is yet to be determined. © Société Internationale de Chirurgie 2012.

Splenic artery aneurysm (SAA) is the most common (60%) of all visceral artery aneurysms. The majority of these cases are asymptomatic, but the presentation of their rupture can vary from abdominal/chest pain to cardiovascular collapse (Sadat U, Dar O, Walsh S, Varty K. Splenic artery aneurysms in pregnancy-a systematic review. Int J Surg. 2008;6(3):261-265.). Although rare, the mortality associated with the rupture is as high as 25% (De Vries JE, Schattenkerk ME, Malt RA. Complications of splenic artery aneurysm other than intraperitoneal rupture. Surgery. 1982;91(2):200-204; Caillouette JC, Merchant EB: Ruptured splenic artery aneurysm in pregnancy. Twelfth reported case with maternal and fetal survival. Am J Obstet Gynecol 1993;168(6 Pt 1):1810-1811) and increases to 75% among pregnant women with a concomitant fetal mortality of 95% (O'Grady JP, Day EJ, Toole AL, et al. Splenic artery aneurysm rupture in pregnancy. A review and case report. Obstet Gynecol. 1977; 50(5):627-630). Because of such high maternal and fetal mortality prompt management of SAAs is of utmost importance. We are presenting a case of a 35-year-old woman with a missed ruptured SAA who after an emergent cesarean section went into profound shock and was unable to be resuscitated. This case illustrates the importance of considering the diagnosis of SAA rupture in hemodynamically unstable peripartum females.

Proper critical care training and management rests on 3 pillars-evidence-based patient care, proficient procedural skills, and compassionate end-of-life (EOL) management. The purpose of this manuscript is to provide a practical guide to EOL management for all bedside practitioners. The manuscript outlines not all but some fundamentally important ethical concepts and provides helpful rules and steps on end-of-life management based on my own personal experience and practice. Moreover, nowhere in the rigorous training of critical care or hospitalist physicians do we teach the procedure for removal of life-sustaining measures. Like any other procedure in medicine, it requires preparation, implementation and conclusion, as well as supervision and repetition to become proficient. Therefore, at the conclusion of this paper, an attempt is made to correct this lack of training by providing such outline and a guide. © SAGE Publications 2011.

Background: Percutaneous endoscopic gastrostomy (PEG) has become a mainstay in providing enteral access for patients with obstructive head and neck tumors. PEG tube placement is considered safe and complications are infrequent. Methods: A comprehensive review of the literature in MEDLINE (1962-2011) was performed. We report herein 3 new cases. Results: The literature search revealed 43 previous cases. The interval between PEG placement and diagnosis of metastasis ranged from 1 to 24 months. Conclusions: Metastatic cancer should be considered in patients with head and neck cancer that have persistent, unexplained skin changes at PEG site, anemia, or guaiac positive stools without a clear etiology. The direct implantation of tumor cells through instrumentation is the most likely explanation, although hematogenous and/or lymphatic seeding is also a possibility. Our review of the literature and clinical experience indicate that the pull technique of PEG placement may directly implant tumor cells at the gastrostomy site. © 2012 Elsevier Inc.

Geisinger's ProvenCare™ Program (for elective coronary artery bypass surgery, total hip replacement, and others) has shown that the principles of reliability science, facilitated by a robust electronic health record and institutional commitment, allow the re-engineering of complicated clinical processes. This eliminates unwarranted variation and promotes the completion of evidence-based elements of care. It has not been established that ProvenCare can be generalized to other institutions. Now, under the auspices of the American College of Surgeons Commission on Cancer, ProvenCare has been adapted to a multi-institutional collaborative for the care of the patient with resectable lung cancer.

Before thoracoscopy became popular in the 1990s, thoracotomy and decortication was the treatment of choice for empyema thoracis not responding to tube thoracostomy. An Institutional Review Board-approved, retrospective review of all patients treated for empyema between September 1, 2006, and August 31, 2009, at Kern Medical Center was conducted. A total of 37 patients (male = 33; female = 4) with a mean age of 43.7 years were treated. Empyema developed after community-acquired pneumonia (CAP) in 27, traumatic hemothorax (TH) in nine, and other cause in one. For 34 of 36 patients (91%), a thoracoscopic approach was successful. Two of 36 patients required conversion to thoracotomy, whereas one patient required an initial thoracotomy in each case as a result of tenacious adhesions. Mean duration of the chest tube was 4.1 days in patients with CAP and 4.6 days in patients with TH. Mean length of stay after surgery was 6 days for patients with CAP and 9.1 days for patients with TH. Five of 37(13.5%) had complications and one patient died (2.7%). Follow-up was complete for 81.1 per cent of patients, none of whom required a subsequent intervention. Compared with the literature, it appears that the conversion rate to thoracotomy, length of chest tube duration, and postoperative length of stay have decreased as experience has increased.
