Is pre-discharge echocardiography indicated for asymptomatic neonates with a heart murmur? A retrospective analysis.

OBJECTIVE The purpose of this study was to determine whether a murmur detected on routine pre-discharge examination of asymptomatic newborn children in the first 48 hours of life warrants further investigation with echocardiography. METHODS We conducted a retrospective review of all echocardiography studies of neonates born at Jordan University Hospital between August, 2007 and June, 2014. Findings on physical examination as well as the indication of the echocardiographic studies were reviewed. We included asymptomatic neonates for whom echocardiographic studies were carried out due to the sole indication of a heart murmur on routine pre-discharge neonatal physical examination. RESULTS Of 309 asymptomatic newborns with murmurs on pre-discharge examination, echocardiography revealed 68 (22%) cases of CHD, with 18 (6%) designated as significant heart disease with anticipated intervention during infancy or childhood. The most common abnormality was ventricular septal defect occurring in 36 cases. Critical heart diseases detected included hypoplastic left heart syndrome in two and aortic valve stenosis in four newborns. CONCLUSIONS Although most asymptomatic neonates with heart murmurs have normal hearts, a small percentage may have significant heart disease. The decision to refer an asymptomatic newborn with a murmur for echocardiography before discharge from the hospital remains controversial and must be supported by other evidence such as murmur characteristics and local trends in parental compliance with follow-up well-baby visits.

Pre-operative total parenteral nutrition improves post-operative outcomes in a subset of Crohn’s disease patients undergoing major abdominal surgery

Abstract Background Despite major advances in the medical management of Crohn’s disease (CD), a significant proportion of patients will require surgery within 5 years of diagnosis. Malnutrition is an independent risk factor for adverse post-operative outcomes following gastrointestinal surgery. Data on the value of pre-operative total parenteral nutrition (TPN) in CD patients are mixed and there is a paucity of data in the biologic era. We aimed to define the role of pre-operative TPN in this population. Methods This was a retrospective cohort study conducted at a tertiary referral center. CD patients who underwent major abdominal surgery were identified. Patients receiving pre-operative TPN were compared to controls. We compared the incidence of 30-day infectious and non-infectious post-operative complications between the two groups. Results A total of 144 CD patients who underwent major abdominal surgery between March 2007 and March 2017 were included. Fifty-five patients who received pre-operative TPN were compared to 89 controls. Twenty-one (14.6%) patients developed infectious complications (18.2% in TPN group vs 12.3% in non-TPN group, P = 0.34) and 23 (15.9%) developed non-infectious complications (14.5% in TPN group vs 16.9% in non-TPN group, P = 0.71). In a multivariate analysis, controlling for differences in baseline disease severity and malnutrition between groups, patients receiving pre-operative TPN for ≥60 days had significantly lower odds of developing non-infectious complications (odds ratio 0.07, 95% confidence interval: 0.01–0.80, P = 0.03). Weight loss of >10% in the past 6 months was a significant predictor of post-operative complications. Conclusions In a subset of malnourished CD patients, TPN is safe and allows comparable operative outcomes to controls. Pre-operative TPN for ≥60 days reduced post-operative non-infectious complications without associated increase in infectious complications.

Risk factors for hepatic steatosis in adults with cystic fibrosis: Similarities to non-alcoholic fatty liver disease

AIM To investigate the clinical, biochemical and imaging characteristics of adult cystic fibrosis (CF) patients with hepatic steatosis as compared to normal CF controls. METHODS We performed a retrospective review of adult CF patients in an academic outpatient setting during 2016. Baseline characteristics, genetic mutation analysis as well as laboratory values were collected. Abdominal imaging (ultrasound, computed tomography, magnetic resonance) was used to determine presence of hepatic steatosis. We compare patients with hepatic steatosis to normal controls. RESULTS Data was collected on 114 patients meeting inclusion criteria. Seventeen patients (14.9%) were found to have hepatic steatosis on imaging. Being overweight (BMI > 25) (P = 0.019) and having a higher ppFEV1 (75 vs 53, P = 0.037) were significantly associated with hepatic steatosis. Patients with hepatic steatosis had a significantly higher median alanine aminotransferase level (27 vs 19, P = 0.048). None of the hepatic steatosis patients had frank CF liver disease, cirrhosis or portal hypertension. We found no significant association with pancreatic insufficiency or CF related diabetes. CONCLUSION Hepatic steatosis appears to be a clinically and phenotypically distinct entity from CF liver disease. The lack of association with malnourishment and the significant association with higher BMI and higher ppFEV1 demonstrate similarities with non-alcoholic fatty liver disease. Long term prospective studies are needed to ascertain whether CF hepatic steatosis progresses to fibrosis and cirrhosis.

Once Versus Twice-Daily Oral Proton Pump Inhibitor Therapy for Prevention of Peptic Ulcer Rebleeding: A Propensity Score-Matched Analysis

Background After inpatient management of upper gastrointestinal bleeding (GIB) due to peptic ulcer disease (PUD), oral proton pump inhibitor (PPI) therapy is recommended at discharge to decrease rebleeding risk and improve ulcer healing. Our aim is to determine whether once-daily oral PPI dosing at hospital discharge is associated with inferior 30-day rebleeding outcomes as compared to twice-daily dosing. Methods We retrospectively identified 233 patients admitted with signs and symptoms of upper GIB found to be due to PUD on upper endoscopy. After inpatient management, patients discharged on once-daily oral PPI were compared to those discharged on twice-daily therapy. We utilized propensity score matching based on Rockall scores to ensure the two groups were closely matched in terms of their baseline rebleeding risk. Primary outcome was the incidence of rebleeding within 30 days. Secondary outcomes were all-cause mortality, blood transfusion requirement, requirement for interventional radiology or surgery. Results Overall, 49 patients were discharged on once-daily and 184 on twice-daily PPI. Recurrent bleeding occurred in 18 patients (7.7%) within 30 days. There was no statistically significant difference in recurrent bleeding rates between once-daily (n = 7, 14.3%) as compared to twice-daily PPI (n = 11, 6%) (P = 0.053). In a 1:1 propensity score matched analysis, there was no statistically significant difference in 30-day recurrent bleeding rate between groups (14% once-daily vs. 4% twice-daily, P = 0.159). There were no differences in secondary outcomes. Conclusions Once-daily oral PPI dosing at hospital discharge was not associated with inferior outcomes compared to twice-daily dosing in patients hospitalized for upper GIB due to PUD.

Adherence to quality indicators and surveillance guidelines in the management of Barrett’s esophagus: a retrospective analysis

Background  Adherence to quality indicators and surveillance guidelines in the management of Barrett’s esophagus (BE) promotes high-quality, cost-effective care. The aims of this study were (1) to evaluate adherence to standardized classification (Prague Criteria) and systematic (four-quadrant) biopsy protocol, (2) to identify predictors of practice patterns, and (3) to assess adherence to surveillance guidelines for non-dysplastic BE (NDBE). Methods  This was a single-center retrospective study of esophagogastroduodenoscopy (EGD) performed for BE (June 2008 to December 2015). Patient demographics, procedure characteristics, and histology results were obtained from the procedure report-generating database and chart review. Adherence to Prague Criteria and systematic biopsies was based on operative report documentation. Multiple logistic regression analysis was performed to identify predictors of practice patterns. Guideline adherent surveillance EGD was defined as those performed within 6 months of the recommended 3- to 5-year interval. Results  In total, 397 patients (66.5 % male; mean age 60.1 ± 12.5 years) had an index EGD during the study period. Adherence to Prague Criteria and systematic biopsies was 27.4 % and 24.1 %, respectively. Endoscopists who performed therapeutic interventions for BE were more likely to use the Prague Criteria (OR: 3.16; 95 %CI: 1.47 – 6.82; P  < 0.01) than those who did not. Longer time in practice was positively associated with adherence to Prague Criteria (OR 1.07; 95 %CI: 1.02 – 1.12; P  < 0.01) but with a lower likelihood of performing systematic biopsies (OR 0.91; 95 %CI: 0.85 – 0.97; P  < 0.01). More than half (55.6 %) of patients with NDBE underwent surveillance EGD sooner (range 1 – 29 months) than the recommended interval. Conclusion  Adherence to quality indicators and surveillance guidelines in BE is low. Operator characteristics, including experience with endoscopic therapy for BE and time in practice predicted practice pattern. Future efforts are needed to reduce variability in practice and promote high-value care.

Proton Pump Inhibitor Use Is Associated With an Increased Frequency of Hospitalization in Patients With Cystic Fibrosis

Background Proton pump inhibitors (PPIs) are among the most commonly prescribed medications in clinical practice. PPI use has been associated with the development of community-acquired pneumonia. With a reported prevalence of gastroesophageal reflux disease (GERD) and PPI use that is higher than the general population, patients with cystic fibrosis (CF) are particularly vulnerable to PPI adverse effects. We sought to explore whether PPI use was associated with a higher number of hospitalizations for CF pulmonary exacerbation. Methods We conducted a longitudinal retrospective review in an academic outpatient setting. Patients > 18 years of age with a diagnosis of CF and at least 1 year of follow-up were eligible for inclusion. Baseline characteristics, PPI use, and details of hospitalization through 1 year of follow-up were collected. Results One hundred fourteen patients met inclusion criteria. Fifty-nine patients (51.7%) were hospitalized at least once in the follow-up year, mean number of hospitalizations was 2.17 (± 1.9). At least 6 months of PPI use was observed in 59 patients (51.7%). In univariate analysis, PPI use was associated with a significantly higher mean number of hospitalizations (0.9 vs. 1.4, P = 0.009). In a multi-variable regression model, PPI use remained significantly associated with a higher number of hospitalizations (P = 0.03), while controlling for risk factors traditionally associated with increased pulmonary exacerbations. Conclusion PPI use is highly prevalent in CF patients. Exposure to PPI therapy is independently associated with a higher number of hospitalizations for pulmonary exacerbation in CF patients.

Hematochezia: An Uncommon Presentation of Colonic Tuberculosis

Abdominal tuberculosis (TB) is an uncommon entity in the United States. Colonic TB is reported in 2-3% of patients with abdominal TB. It is frequently misdiagnosed as Crohns disease or carcinoma of the colon due to their shared clinical, radiographic, and endoscopic presentations. We present a case of a 72-year-old male with colonic tuberculosis presenting as hematochezia. Our patient presented with shortness of breath and weight loss. Chest X-ray demonstrated ill-defined bilateral parenchymal opacities in the perihilar, mid, and lower lung zones. The patient was diagnosed and treated for community acquired pneumonia, with no improvement. Hematochezia complicated by symptomatic hypotension developed later in the course of admission. Colonoscopy revealed multiple ulcers at the anus and transverse and ascending colon as well as the cecum with stigmata of bleeding. Biopsy of a sigmoid ulcer was consistent with colonic tuberculosis. Antitubercular therapy was initiated, but the patient passed away secondary to multiorgan failure 29 days into admission.

Facial palsy and atrial fibrillation: a special case of Ramsay Hunt syndrome

Ramsay Hunt syndrome (herpes zoster oticus) is a rare complication of latent Varicella Zoster virus infection. It can be complicated by permanent hearing loss, loss of taste and postherpetic neuralgia. Although Ramsay Hunt syndrome most prominently involves the facial nerve, a number of other cranial nerves can be involved such as the vestibulocochlear, glossopharyngeal and the vagus nerve. We report on a case of Ramsay Hunt syndrome with cranial polyneuritis complicated by atrial fibrillation. Vagal involvement as evidenced by physical examination and MRI findings was present in our patient. We hypothesise that viral vagal neuritis likely contributed to the development of atrial fibrillation in our patient through involvement of the autonomic components of the vagus nerve.

Circumferential stent fracture repaired using a covered stent in a 42-year-old man with coarctation of the aorta

We present a case of circumferential fracture of aortic coarctation stent with severe re-stentosis presenting 16 years after initial stent implantation with end-stage renal disease. The patient was treated with a covered stent using the stent-in-stent technique. The use of an ultra-high-pressure balloon was proved necessary to overcome the tight, non-compliant stenosis.

Atretic aortic coarctation in a 32-year-old woman diagnosed after her third pregnancy, treated percutaneously using a covered stent

Atretic aortic coarctation is a severe form of coarctation of aorta, where there is loss of luminal communication at the site of aortic isthmus. We present a case of a 32-year-old woman who had long-standing, treatment-resistant hypertension. She had three pregnancies. The third pregnancy ended in premature labor of a newborn female infant who was found to have severe coarctation of aorta. This diagnosis in the newborn child prompted proper evaluation of the mother, who was found to have atretic coarctation. The woman was treated successfully using a covered Advanta V12 stent (Atrium, Hudson, NH, USA), after percutaneous needle puncture of the atretic isthmus. Anatomical orientation of the aorta at the site of coarctation and its relationship to the safety of needle puncture approach are discussed. This case brings an old lesson to the table, where proper evaluation of severe, treatment-resistant hypertension in adults should include screening for secondary causes. <Learning objective: Evaluation of severe and resistant systemic hypertension in adults should include screening for aortic coarctation. Pregnancy in women with coarctation of aorta carries significant risk to both the woman and the fetus. Atretic coarctation is a severe form of coarctation where there is complete obstruction of aortic isthmus. This can be treated successfully by percutaneous approach using covered stents.>.
