Constipation is a common problem in pediatrics and accounts for 3-5% of all pediatric office visits and 10-25% of all pediatric gastroenterology referrals. Functional constipation accounts for about 95% of constipation cases, but "red flag" symptoms that suggest organic causes need to be considered. A diagnosis of functional constipation can be made in absence of "red flag" symptoms and a normal physical assessment. Physical assessment should focus on growth, abdominal exam, inspection of the perianal region, and examination of the lumbosacral region. Abdominal x-rays are generally not useful to differentiate between functional and organic causes of constipation. Treatment of constipation includes dietary changes, medication use, and behavioral modification. Osmotic laxatives are used as first-line treatment, and stimulant laxatives can be added if there is no improvement with osmotic laxatives. Despite improvement with laxatives, 40-50% of children with constipation experience at least 1 relapse in 5 years. Quality improvement opportunities exist for improving care of children with functional constipation by specialists partnering with primary care.Our objective was to evaluate hand-held echocardiography as point of care ultrasound scanning (POCUS) to detect sources of embolism in the acute phase of stroke. Prospective, unicentric observational cohort study of non-lacunar ischemic stroke patients evaluated by V Scan device. The main sources of embolism (MSEs) were classified into embolic valvulopathies and severe ventricular dysfunction. We looked for atrial fibrillation (AF) predictors in strokes of undetermined etiology. MSEs were detected in 19.23% (25/130). Large vessel occlusion (LVO) (odds ratio [OR] 4.24, 95% confidence interval [CI] 1.01-17.85) and chronic heart failure (OR 13.25, 95% CI 3.54-49.50) were independent predictors of MSEs. LVO (OR 6.54, 95% CI 1.62-26.27) and left atrial area &gt;20 cm2 (OR 7.01, 95% CI 1.75-28.09) independently predicted AF. Patients with LVO and chronic heart disease may benefit from hand-held echocardiography as part of POCUS in the acute phase of ischemic stroke. Left atrial area measured was an independent predictor of AF in strokes of undetermined etiology.Objectives Postoperative delirium, associated with negative consequences including longer hospital stays and worse cognitive and physical outcomes, is frequently accompanied by sleep-wake disturbance. Our objective was to evaluate the efficacy and short-term safety of ramelteon, a melatonin receptor agonist, for the prevention of postoperative delirium in older patients undergoing orthopedic surgery. Design A quadruple-masked randomized placebo-controlled trial (Clinical Trials.gov NCT02324153) conducted from March 2017 to June 2019. Setting Tertiary academic medical center. Participants Patients aged 65 years or older, undergoing elective primary or revision hip or knee replacement. Intervention Ramelteon (8 mg) or placebo MEASUREMENTS Eighty participants were randomized to an oral gel cap of ramelteon or placebo for 3 consecutive nights starting the night before surgery. Trained research staff conducted delirium assessments for 3 consecutive days starting on postoperative day (POD) 0, after recovery from anesthesia, and on to POD2. A delirium diagnosis was based upon DSM-5 criteria determined by expert panel consensus. Results Of 80 participants, five withdrew consent (one placebo, four ramelteon) and four were excluded (four ramelteon) after randomization. Delirium incidence during the 2 days following surgery was 7% (5 of 71) with no difference between the ramelteon versus placebo 9% (3 of 33) and 5% (2 of 38), respectively. The adjusted odds ratio for postoperative delirium as a function of assignment to the ramelteon treatment arm was 1.28 (95% confidence interval 0.21-7.93; z-value 0.27; p-value = 0.79). Adverse events were similar between the two groups. Conclusion In older patients undergoing elective primary or revision hip or knee replacement, ramelteon was not efficacious in preventing postoperative delirium.Objective To evaluate the effects of hyperglycemia on body composition and neurodevelopment, and how early nutrition and illness modify these relationships in infants born preterm. Study design Prospective data were collected from infants born 150 mg/dL) and nutrient intake. Body composition was measured at discharge and 4 months' postmenstrual age (PMA). Bayley Scales of Infant Development III (BSID-III) were administered at 12 months' PMA. Linear regression analysis was performed, adjusting for birth gestational age. Associations between hyperglycemia, body composition, and BSID-III were analyzed in models accounting for first-week nutrition and early illness severity via Score for Neonatal Acute Physiology-II. Results Mean birth gestational age was 27.8 (SD 2.4) weeks. Hyperglycemia occurred in 48.5% of infants. Hyperglycemia for ≥5 days was negatively associated with fat mass and fat free mass z scores at discharge, and fat free mass z score at 4 months' PMA (P less then .05 all). Hyperglycemia for ≥5 days was negatively associated with cognition, language, and motor scores on the BSDI at 12 months (P ≤ .01 all). Associations with body composition and BSID-III were diminished when models included first week nutrition yet remained unchanged when illness severity was included. Conclusions In infants less then 32 weeks, ≥5 days of hyperglycemia is associated with decreased lean mass at 4 months' PMA and poorer neurodevelopmental outcome at 12 months' PMA. These associations may be mediated by decreased first week nutrition, potentially related to reduced glucose infusion rate for management of hyperglycemia.Objective To detail common comorbidities and procedures performed to evaluate functional nausea in children. [https://www.selleckchem.com/products/pds-0330.html PDS-0330] Study design In total, 63 children age 7-18 years seen in a tertiary care pediatric clinic who met Rome IV criteria for functional nausea prospectively completed an Intake Questionnaire, the Pediatric and Parent-Proxy PROMIS-25 Profile v 2.0, the Pediatric and Parent-Proxy Pediatric Sleep Disturbance-Short Form 4a, and the COMPASS 31 orthostatic intolerance scale to assess comorbidities. Medical records were reviewed for diagnostic tests performed to evaluate nausea and for additional comorbidities. Summary statistics were used to determine the most common comorbidities and diagnostic yield of the procedures. Intraclass correlation coefficients assessed agreement between parent and child reports on the PROMIS scales. Results Patients with functional nausea experienced multisystem comorbidities. A majority reported abdominal pain, headache, orthostatic intolerance, fatigue, disturbed sleep, anxiety, constipation, allergies, and vomiting.
