Fallopian Tube Torsion in the Pediatric Age Group

Fallopian tube torsion is a rare but important cause of acute pelvic pain in young adolescent girls. It is a surgical emergency treated with either detorsion or salpingectomy. The imaging findings can be nonspecific and challenging. However, an accurate early diagnosis is essential for prompt surgical treatment. Our objective was to review whether imaging findings can be specific enough to suggest the diagnosis of tubal torsion prospectively in the appropriate clinical setting. An Institutional Review Board–approved retrospective review of our imaging database from 2005 to 2012 revealed 10 surgically proven cases of fallopian tube torsion. All cases had sonography performed; 5 cases had additional multidetector computed tomography. All 10 patients (9–17 years) presented with acute pelvic pain. Sonographic findings included dilated tubular structures in 6 of 10 cases: adjacent to a normal ipsilateral ovary in 5 of 6 and adjacent to a benign ovarian teratoma in 1. In 4 cases, no dilated tube was identified; 3 of 4 had a cystic mass separate from the ovaries, and 1 had the imaging appearance of a multicystic ovary. Computed tomographic findings in the 5 cases that underwent multidetector computed tomography included a dilated tubular structure in 3 of 5; 2 of 5 had a cystic adnexal mass identified. Although rare, tubal torsion should be considered in female adolescents with acute pelvic pain. Sonography should be the first imaging choice. When a tubular structure or a midline cystic mass associated with a normal ipsilateral ovary is noted, tubal torsion should be considered in the differential diagnosis.     

Examination of concordance between maternal and youth reports in the diagnosis of pediatric bipolar disorder

Objective:  While concordance between mother and child report continues to be the gold standard in the assessment of pediatric bipolar disorder, uncertainty develops when a mother's report is not endorsed by the youth. To this end we compared discordant (mother positive and youth negative) and concordant (mother and youth positive) cases.
Methods:  Subjects were 98 adolescents (12–19 years of age) derived from family studies of bipolar disorder in youth who had both self-reported and mother-reported assessments. Comparisons were made between discordant (n = 35) and concordant (n = 59) cases on a wide range of clinical correlates.
Results:  Mothers in both groups reported similar rates of symptoms of mania and depression. Within the concordant group, mothers and youth reported similar rates of symptoms of mania. There were no differences between the concordant and discordant groups in onset, duration, or impairment of mania, rates of psychiatric hospitalization, cognitive variables, or rates of disorders in family members.
Conclusions:  The similarities between discordant and concordant reports in symptomatology of mania and depression, rates of comorbidities, treatment needs, and other clinical correlates suggest that a mother-based diagnosis of mania should not be discounted in discrepant cases in which the youth fails to endorse the diagnosis.     

Recovery Factors Affecting Utilization of Small Pediatric Donor Kidneys

Kidneys from small pediatric donors are underutilized. Using data from the Scientific Registry of Transplant Recipients for donors <21 kg in which at least one organ was recovered from 1997 to 2007 (n = 3341), donor and recovery factors were evaluated by multivariate analysis for associations with (a) kidney nonrecovery and (b) transplantation of recovered kidneys. Results: The proportion of kidney recoveries were 55% during liver procurements and 40% during intestine procurements amongst donors <10 kg (p < 0.01) compared to 93% and 88%, respectively, for donors weighing 10–20 kg (p = 0.003). Intestine procurement was independently associated with an 81% greater likelihood of kidney nonrecovery (p < 0.0001) and a 48% lower likelihood of transplantation (p = 0.0004). A multivariate Cox model indicated that single kidney recipients had a 63% higher risk of graft failure compared with en bloc kidney recipients (p < 0.0001); however, concurrent intestine recovery was not a significant risk factor for graft loss. Intestine recovery from donors <21 kg of age is strongly associated with higher kidney nonrecovery and lower transplantation rates. Graft survival is worse with single kidney transplantation, but is not significantly affected by intestine recovery. Small pediatric donors procurement teams should strive to increase kidney recoveries overall and en bloc recoveries in particular.     

Linear Growth Patterns in Prepubertal Children Following Liver Transplantation

Factors impacting linear growth following pediatric liver transplantation (LT) are not well understood. This longitudinal analysis examines predictors of linear growth impairment in prepubertal children included in Studies of Pediatric Liver Transplantation. In 1143 children with serial measurements, mean height scores increased from −1.55 at LT to −0.87 and −0.68 at 24 and 36 months post LT with minimal subsequent catch up growth observed until 60 months. Subgroup analysis of height measurements at 24 months (n = 696), 33.8% were below 10th percentile at 24 months post LT. Multivariate analysis revealed linear growth impairment more likely in patients with metabolic disease (OR 4.4, CI: 1.83–10.59) and >18 months of steroids exposure (OR 3.02, CI: 1.39–6.55). Higher percentiles for weight (OR 0.80, CI: 0.65–0.99) and height (OR 0.62, CI: 0.51–0.77) at LT decreased risk. Less linear catch up was observed in patients with metabolic disease, non-Biliary atresia cholestatic diseases and lower weight and higher height percentiles prior to LT. Prolonged steroid exposure and elevated calculated glomerular filtration rate and γ-Glutamyltransferase following LT were associated with less catch up growth. Linear growth impairment and incomplete linear catch up growth are common following LT and may improve by avoiding advanced growth failure before LT and steroid exposure minimization.     

Health,Emergency Department Use,and Early Identification of Young Children Exposed to Trauma

Background

Childhood trauma is an important public health problem with financial, physical health, and mental health repercussions. Emergency departments (EDs) are often the first point of contact for many young children affected by emotionally or psychologically traumatic events (e.g., neglect, separation from primary caregiver, maltreatment, witness to domestic violence within the family, natural disasters).

Study Objectives

Describe the prevalence of physical health symptoms, ED use, and health-related problems in young children (birth through 5 years) affected by trauma, and to predict whether or not children experiencing trauma are more likely to be affected by health-related problems.

Methods

Community-based, cross-sectional survey of 208 young children. Traumatic events were assessed by the Traumatic Events Screening Inventory – Parent Report Revised. Child health symptoms and health-related problems were measured using the Caregiver Information Questionnaire, developed by ORC Macro (Atlanta, GA).

Results

Seventy-two percent of children had experienced at least one type of traumatic event. Children exposed to trauma were also experiencing recent health-related events, including visits to the ED (32.2%) and the doctor (76.9%) for physical health symptoms, and recurring physical health problems (40.4%). Children previously exposed to high levels of trauma (four or more types of events) were 2.9 times more likely to report having had recently visited the ED for health purposes.

Conclusions

Preventing recurrent trauma or recognizing early trauma exposure is difficult, but essential if long-term negative consequences are to be mitigated or prevented. Within EDs, there are missed opportunities for identification and intervention for trauma-exposed children, as well as great potential for expanding primary and secondary prevention of maltreatment-associated illness, injury, and mortality.     

Cranial Computed Tomography Utilization for Suspected Ventriculoperitoneal Shunt Malfunction in a Pediatric Emergency Department

Background

Computed tomography (CT) scan, the largest medical source of ionizing radiation in the United States, is used to test for failure of ventricular peritoneal shunts.

Study Objectives

To quantify the exposure to cranial CT scans in pediatric patients presenting with symptoms of shunt malfunction, and to measure the association of signs and symptoms with clinical shunt malfunction and the need for neurosurgical intervention within 30 days of presentation.

Method

This was a quality improvement study evaluating a pathway used by providers in a tertiary care pediatric emergency department with 85,000 patient visits per year, by retrospective chart review of 223 patient visits for suspected shunt malfunction. We determined the median CT scan per patient per year and the association of signs and symptoms on the pathway with radiological signs of shunt failure and neurosurgical intervention within 30 days of scan.

Results

The median exposure was 2.6 (interquartile range 1.44–4.63) scans per patient per year. Among 11 signs and symptoms, none was associated with radiologic shunt failure. Neurosurgical intervention within 30 days was positively associated with bulging fontanelle (adjusted odds ratio [AOR] 11.78; 95% confidence interval [CI] 1.67–83.0) and behavioral change (AOR 3.01; 95% CI 1.14–7.93), and negatively associated with seizure (AOR 0.13; 95% CI 0.02–0.79) and fever (AOR 0.15; 95% CI 0.04–0.55).

Conclusions

Patients with ventricular peritoneal shunts underwent many cranial CT scans each year. None of the signs or symptoms included on the clinical pathway was predictive of changes on CT scan.
