Vaginal Delivery After Ileal Pouch-Anal Anastomosis: A Word of Caution

PURPOSE This study was designed to evaluate the impact of childbirth on anal sphincter integrity and function, functional outcome, and quality of life in females with restorative proctocolectomy and ileal pouch-anal anastomosis.METHODS The patients who had at least one live birth after ileal pouch-anal anastomosis were asked to return for a comprehensive assessment. They were asked to complete the following questionnaires: the Short Form-36, Cleveland Global Quality of Life scale, American Society of Colorectal Surgeons fecal incontinence severity index, and time trade-off method. Additionally, anal sphincter integrity (endosonography) and manometric pressures were measured by a medical physician blinded to the delivery technique. Anal sphincter physiology also was evaluated with electromyography and pudendal nerve function by nerve terminal motor latency technique.RESULTS Of 110 eligible females who had at least one live birth after ileal pouch-anal anastomosis, 57 participated in the study by returning for clinical evaluation to the clinic and 25 others by returning the quality of life and functional outcome questionnaires. Patients were classified into two groups: patients who had only cesarean section delivery after ileal pouch-anal anastomosis (n = 62) and patients who had at least one vaginal delivery after ileal pouch-anal anastomosis (n = 20). The mean follow-up from the date of the most recent delivery was 4.9 years. The vaginal delivery group had significantly higher incidence of an anterior sphincter defect by anal endosonography (50 percent) vs. cesarean section delivery group (13 percent; P = 0.012). The mean squeeze anal pressure was significantly higher in the patients who had only cesarean section delivery (150 mmHg) after restorative proctocolectomy than patients who had at least one vaginal delivery (120 mmHg) after restorative proctocolectomy (P = 0.049). Quality of life evaluated by time trade-off method also was significantly better in the cesarean section delivery group (1) vs. vaginal delivery group (0.9; P < 0.001).CONCLUSIONS The risk of the sphincter injury and quality of life measured by time trade-off method are significantly worse after vaginal delivery compared with cesarean section in patients with ileal pouch-anal anastomosis. In the short-term, this does not seem to substantially influence pouch function or quality of life; however, the long-term effects remain unknown, thus obstetric concern may not be the only factor dictating the type of delivery in this group of patients. A planned cesarean section may eliminate these potential and factual concerns in ileal pouch-anal anastomosis patients.Podium presentation at the meeting of The American Society of Colon and Rectal Surgeons, Dallas, Texas, May 8 to 13, 2004.     

Care processes and clinical outcomes of continuous outpatient support with inotropes (COSI) in patients with refractory endstage heart failure

BACKGROUND: This study describes the process and outcomes of continuous outpatient support with inotropes (COSI) in patients with Stage D heart failure (HF). Although Stage D HF has recently been defined as end-stage disease requiring special interventions for survival such as COSI or ventricular assist devices, concern has been raised regarding the safety, efficacy, mortality outcomes, and ethics of COSI. METHODS AND RESULTS: Inotrope dependence was defined as worsening of the patient's clinical status with attempted inotrope withdrawal such that the patient was deemed unlikely to survive to permit hospital discharge. A care process for COSI was designed; baseline and outcome variables were evaluated. COSI was administered to 36 inotrope-dependent patients (age 55.4 +/- 9.5 years, 24 males). Baseline characteristics (mean +/- SD) were consistent with Stage D HF: left ventricular ejection fraction 19.9 +/- 8.5, left ventricular end-diastolic dimension (LVEDD) 70 +/- 10 mm, systolic blood pressure 97.4 +/- 13.4 mm Hg, serum creatinine 1.5 +/- 0.6, serum sodium 131.7 +/- 5.3; 69 HF hospitalizations (mean 1.9 +/- 1.8) 6 months before COSI initiation. Symptomatic hypotension, increasing dyspnea, renal dysfunction, and hypoperfusion most commonly prevented inotrope withdrawal. Despite Stage D HF, patients were discharged with COSI ambulatory, oriented, and pain free. Rehospitalizations were 46; 6 subjects accounted for 24 hospitalizations; 23 had 0 or 1 rehospitalization. Median survival was 3.4 months (range 0.2-26.3 months); and 3-, 6-, and 12-month Kaplan Meier survival was 51%, 26%, and 6%, respectively. The majority of patients died at home and chose to not undergo resuscitation attempts. CONCLUSION: COSI may be an acceptable treatment option for Stage D HF.     

Macrophage impairment underlies airway occlusion in primary respiratory syncytial virus bronchiolitis

Although respiratory syncytial virus (RSV) infection is the most important cause of bronchiolitis in infants, the pathogenesis of RSV disease is poorly described. We studied histopathologic changes in a panel of lung tissue specimens obtained from infants with fatal cases of primary RSV infection. In these tissues, airway occlusion with accumulations of infected, apoptotic cellular debris and serum protein was consistently observed. Similar observations were found after RSV infection in New Zealand black (NZB) mice, which have constitutive deficiencies in macrophage function, but not in BALB/c mice. A deficiency in the number of alveolar macrophages in NZB mice appears to be central to enhanced disease, because depletion of alveolar macrophages in BALB/c mice before RSV exposure resulted in airway occlusion. In mice with insufficient numbers of macrophages, RSV infection yielded an increased viral load and enhanced expression of type I interferon-associated genes at the height of disease. Together, our data suggest that innate, rather than adaptive, immune responses are critical determinants of the severity of RSV bronchiolitis.     

Enteroviruses,hygiene and type 1 diabetes: toward a preventive vaccine

Enteroviruses and humans have long co‐existed. Although recognized in ancient times, poliomyelitis and type 1 diabetes (T1D) were exceptionally rare and not epidemic, due in large part to poor sanitation and personal hygiene which resulted in repeated exposure to fecal–oral transmitted viruses and other infectious agents and viruses and the generation of a broad protective immunity. As a function of a growing acceptance of the benefits of hygienic practices and microbiologically clean(er) water supplies, the likelihood of exposure to diverse infectious agents and viruses declined. The effort to vaccinate against poliomyelitis demonstrated that enteroviral diseases are preventable by vaccination and led to understanding how to successfully attenuate enteroviruses. Type 1 diabetes onset has been convincingly linked to infection by numerous enteroviruses including the group B coxsackieviruses (CVB), while studies of CVB infections in NOD mice have demonstrated not only a clear link between disease onset but an ability to reduce the incidence of T1D as well: CVB infections can suppress naturally occurring autoimmune T1D. We propose here that if we can harness and develop the capacity to use attenuated enteroviral strains to induce regulatory T cell populations in the host through vaccination, then a vaccine could be considered that should function to protect against both autoimmune as well as virus‐triggered T1D. Such a vaccine would not only specifically protect from certain enterovirus types but more importantly, also reset the organism's regulatory rheostat making the further development of pathogenic autoimmunity less likely.

Are pressure injuries related to skin failure in critically ill patients?

Background

Pressure injuries contribute significantly to patient morbidity and healthcare costs. Critically ill patients are a high risk group for pressure injury development and may suffer from skin failure secondary to hypoperfusion. The aim of this study was to report hospital acquired pressure injury incidence in intensive care and non-intensive care patients; and assess the clinical characteristics and outcomes of ICU patients reported as having a hospital acquired pressure injury to better understand patient factors associated with their development in comparison to ward patients.
