The LCI is elevated early in CF, especially in the presence of Pseudomonas and airway inflammation. The LCI is a feasible, repeatable, and sensitive noninvasive marker of lung disease in young children with CF.
The management of malrotation when it is an incidental finding is unclear. This retrospective study reports an analysis of radiological and operative findings in a series of 71 patients. There were no deaths. We report a false-positive rate of 15% for upper gastrointestinal contrast studies reported as showing malrotation. Our findings and a review of the literature demonstrate that in the asymptomatic child over 2 years of age, the evidence supporting mandatory correction of malrotation is weak.
Factors relating to the child (effortful control) and parent (coping and distress-promoting behaviors) both contribute to children's response to an aversive medical procedure. Interventions that facilitate parent coping and promoting behavior, reduce their distress-promoting behavior, and compensate for children's infrequent and ineffective use of coping strategies (such as distraction) may be optimal for young children, particularly those low in effortful control.
Successful reduction of an intussusception does not always rule out a lead point. Other imaging studies, the patient's condition, and laparotomy may also be necessary to diagnose and treat lead points and other lesions.
The diagnostic efficacy of ultrasound (US) in the diagnosis of infantile hypertrophic pyloric stenosis (IHPS) was evaluated, with particular attention paid to whether prematurity, age or weight correlate significantly to the sonographic measurements. The medical records of 187 infants with suspected IHPS were reviewed retrospectively. Eighty-seven had an US examination with details of the pylorus. Fifty-nine of these gave a positive diagnosis. The US criteria for a positive diagnosis were pyloric muscle thickness (PMT)>or=3 mm and pyloric muscle length (PML)>or=17 mm. The mean overall PMT was 4.14 mm and mean overall PML was 18.99 mm. Premature infants had a lower mean PML (17.8 mm) than the term infants (PML mean 19.3 mm); however, this was not significant (t-value 1.92, P=0.062). The sensitivity and specificity of PMT was 91 and 85%, respectively, and of PML 76 and 85%, respectively. The ability of US to diagnose IHPS using our criteria was significant (t-value, PMT 14.93 and PML 6.89; P<0.0001). There was no significant correlation between age, weight or prematurity and a sonographic diagnosis of IHPS (Pearson's coefficient<0.3). Therefore, the same US criteria should apply irrespective of prematurity, age or weight. Borderline PMT and PML measurements necessitate repeat US or alternative imaging.
Angiography with selective embolization is a safe and effective method to correct posttraumatic priapism in children. Color Doppler sonography is a valuable preangiographic study, as it allows for characterization and localization of the causative lesion and obviates diagnostic cavernosal aspiration.
We present a case of duplication of the pituitary gland with associated clefts of the hard palate and body of the sphenoid and a midline palatine dermoid. This is an extremely rare malformation with only six previous case reports in the literature. Imaging findings are discussed and literature reviewed for possible morphogenesis, including its association with partial twinning and midline cleft face syndrome.
The purpose of this study was to compare the concurrent use of chloral hydrate (CH), intramuscular Nembutal (IMN) and intravenous Nembutal (IVN) for sedation. Data was collected on all pediatric outpatients requiring sedation for CT over a 2.5-year period. During this period, 2178 outpatients required sedation of whom, 1324 (60.8%) received IMN, 710 (32.6%) IVN and 110 (5%) CH. The overall success rate was 97% and was similar in all three groups. IVN however, produced better-quality sedation than IMN or CH. The IVN group received a significantly lower dose of Nembutal than the IMN group (p = 0.001). Patients receiving IVN had a significantly lower induction time (p = 0.0001) and total examination time (p = 0.001) than IMN or CH. There was an increased occurrence of desaturation in patients sedated with IVN, especially in those with airway obstruction. IVN sedation permits faster, more efficient and better-quality sedation for outpatient CT scanning than IMN or CH in patients requiring intravenous contrast but may not be appropriate for departments that perform relatively few sedations or lack proper resuscitation facilities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
