Understanding the utility of "Talk-to-Me" an online suicide prevention program for Australian university students.

BACKGROUND: Australian university students are at risk of experiencing poor mental health, being vulnerable to self-harm and suicidal ideation. AIM: "Talk-to-Me" is a suicide ideation prevention Massive open online course (MOOC) previously showing it can support Western Australian university students' knowledge of identifying and responding to suicide ideation in themselves and others. METHODS: A multi-site one-group pre-test/post-test design with a 12-week follow-up explored the efficacy of "Talk-to-Me" for university students Australia-wide, evaluating the influence of COVID-19 and location. Overall, 217 students (55% female; mage = 24.93 years [18, 60]) enrolled in this study from 2020 to 2021. Participants' responses to suicidal statements, mental health literacy, generalized self-efficacy, help-seeking behavior, and overall utility of the program were collected at baseline, post-MOOC (10 weeks from baseline) and 12-week follow-up. The effect of time and location interaction was explored using a random-effects regression model. RESULTS: Findings indicated significant improvement in participants' knowledge of positive mental health support strategies (ES = 0.42, p < 0.001) and recognizing appropriate responses to suicidal statements (ES = 0.37, p < 0.001) at 10-weeks, with further improvement at 12 weeks follow-up (ES = 0.47 and 0.46, p < 0.001). Students reported higher generalized self-efficacy at the 12-week follow-up compared to baseline (ES = 0.19, p = 0.03) and an increased tendency to seek professional help for mental health issues (ES = 0.22, p = 0.02). CONCLUSION: These findings provide preliminary evidence of the efficacy of the "Talk-to-Me" program in supporting university students across Australia to increase their suicide-related knowledge and skills, general self-efficacy, and overall mental fitness.

Program evaluation of an adapted PEERS® social skills program in young adults with autism spectrum disorder and/or mild intellectual impairment and social skills difficulties.

RATIONALE, AIMS AND OBJECTIVES: Social challenges are common for young adults with autism spectrum disorder (ASD) and/or mild intellectual impairment, yet few evidence-based interventions exist to address these challenges. PEERS®, the Program for the Education and Enrichment of Relational Skills, has been shown to be effective in improving the social skills of young adults with ASD; however, it requires a significant time commitment for parents of young adults. As such, this mixed-methods study aimed to investigate the experiences of young adults, parents and PEERS® social coaches participating in an adapted PEERS® program, and to evaluate its acceptability and efficacy. METHOD: Young adults with ASD and/or mild intellectual impairment participated in a 16-week PEERS® program. Parents and PEERS® social coaches attended fewer, condensed sessions, where they learnt program content to support the young adults' social skill development at home and in the community. Focus groups were conducted post intervention. Quantitative pre-post assessment using the Social and Emotional Loneliness Scale for Adults, the Test of Young Adult Social Skills Knowledge, and Quality of Socialization Questionnaire-Young Adults was completed by young adults. The Social Responsiveness Scale Second Edition was completed by young adults and their parents. RESULT: Qualitative results revealed that, taken together, young adults, parents and PEERS® social coaches all felt that the adapted PEERS® program was 'challenging, but worth it'. The program was acceptable with a 93% attendance rate across all sessions. Whilst young adults' perceptions of their own social functioning did not change post-intervention, their knowledge of social skills content improved significantly (p < 0.05). Parent perceptions of young adults' social responsiveness also improved (p < 0.05). CONCLUSIONS: Social skill knowledge, social responsiveness, and social engagement improved significantly following the completion of the adapted PEERS® program. It was deemed acceptable and worthwhile by young adults, their parents and PEERS® social coaches.

BrightHearts: A pilot study of biofeedback assisted relaxation training for the management of chronic pain in children with cerebral palsy.

Background: Chronic pain is estimated to impact one-in-three children with cerebral palsy (CP). Psychological interventions including behavioral and cognitive strategies play a key role in chronic pain management, but there is a paucity of research exploring their use in children with CP. Aim: To investigate the acceptability and feasibility of biofeedback assisted relaxation training (BART) for chronic pain management in children with CP using a mixed-methods study design. Methods: Biofeedback assisted relaxation training was delivered via BrightHearts, an iOS application. Inclusion criteria were as follows: CP; self-reported chronic pain; age 9-18 years; and fluent English speaker. Children used BrightHearts for ten minutes daily, over four weeks. Qualitative post-intervention interviews were undertaken (child, parent) and quantitative pre-post measures (child) were gathered including pain intensity (numerical rating scale), and anxiety intensity (numerical rating scale). Content analysis was conducted for qualitative data. Descriptive statistics and exploratory analyses were performed for quantitative data. Results: Ten children participated (n = 3 male, mean age = 13.1 years SD = 2.5 years, GMFCS level I = 4, II = 2, III = 3, IV = 1). Predominant movement disorder was spasticity (n = 7) and dyskinesia, mainly dystonia (n = 3). Content analysis suggested an overarching theme "BrightHearts is a good thing to put in my toolbox" providing an overall representation of participants' experiences. For many, BrightHearts was a valuable supplement to children's pain management strategies: "The source of the pain is still there, but the actual effect of the pain isn't so relevant." Four sub-themes were identified: "Managing my pain;" "Managing my anxiety and stress," "Helping me do what I need to do;" and "Fitting it into my life." Some participants reported improvements in their anxiety management, and others described benefits in sleep and school following improved pain/anxiety management. A range of practical and personal factors within this heterogeneous group presented barriers to using BrightHearts including limited time, attention, and boredom. Seven-out-of-eight children would recommend BrightHearts to others with chronic pain and six-out-of-eight noticed a difference in their pain since using BrightHearts (n = 2 missing data). Non-significant reductions in pain or anxiety intensity scores were found following the intervention. Conclusion: This pilot suggests BrightHearts is an acceptable and feasible intervention for chronic pain management in children with CP and may be useful for some children as part of a multimodal approach.

Lived experiences of pain in children and young people with cerebral palsy.

AIM: To explore the lived experiences of pain in children and young people with cerebral palsy (CP). METHOD: Participants were recruited from the Sydney Children's Hospitals Network and the New South Wales/Australian Capital Territory CP Registers. Inclusion criteria were as follows: CP; aged 9 to 17 years; current/past experience of pain; fluent in English; no greater than mild intellectual disability. Purposive sampling ensured representation across age, motor subtypes, and Gross Motor Function Classification System (GMFCS) levels. Semi-structured face-to-face interviews were conducted. Data were analysed following an interpretative phenomenological approach. RESULTS: Ten participants (three male) were included (mean age 14y 5mo, SD 2y), GMFCS levels I (n=4), II (n=3), III (n=2), and IV (n=1). Analysis led to three superordinate themes: (1) Everybody's experience of pain is different; (2) When the pain is winning; (3) 'I know how to deal with it'. Pain contributors and locations varied between children. Pain intruded on school, physical activity, and psychosocial functioning. Children described personalized strategies used to deal with pain. INTERPRETATION: In this study, children self-reported highly individualized pain experiences which interfered with their daily life and psychosocial well-being. There is a need for improvement in pain assessment and a personalized approach to pain management.

Acute Kidney Injury After Large Ventral Hernia Repair Requiring Transversus Abdominis Release.

BACKGROUND: Acute kidney injury (AKI) is a known postoperative complication of open ventral hernia repair contributing to increased costs, hospital length of stay, and mortality. The aim of this study was to identify whether the muscle injury that occurs in a posterior separation of components via transversus abdominis release (TAR) contributes to a higher incidence of postoperative AKI. METHODS: A retrospective cohort study of patients who underwent open retrorectus ventral hernia repair with and without TAR at a single institution between 2012 and 2019 was performed. Patients who underwent a separation of components via either unilateral or bilateral transversus abdominis release were compared to those who did not undergo TAR as part of their hernia repair (non-TAR). The outcome of interest was the development of postoperative AKI. Acute kidney injury was defined as an increase in creatinine of greater than 50% of the preoperative baseline. Univariate and multivariate analyses were performed to determine the influence of TAR on the development of AKI. RESULTS: There were 523 patients who met inclusion criteria, of which 159 (30.4%) had a TAR as part of their retrorectus hernia repair. No differences were found in preoperative characteristics between the TAR and non-TAR group including age, gender, history of kidney disease, or history of diabetes. By contrast, the TAR group had significantly greater median estimated blood loss (100 mL vs 75 mL, P < .01), mean positive intraoperative fluid balance (2255 mL vs 1887 mL, P < .01), and operative duration (321 min vs 269 min, P < .001). The rate of AKI in the TAR group was 11% (n = 18) vs 6% (n = 23, P = .0503) in the non-TAR group. On multivariate analysis controlling for patient characteristics and intraoperative factors, TAR was the only factor with a significantly increased odds of AKI (OR 1.97, 95% CI 0.994-3.905, P = .0521). CONCLUSIONS: In patients with large ventral hernias requiring retrorectus repair, performing a TAR is associated with a nearly 2-fold increase in the development of postoperative AKI. These findings suggest that these patients should be optimized perioperatively with emphasis on fluid resuscitation, limiting nephrotoxic medications and monitoring urine output.

Does the false-negative rate for 1 or 2 negative sentinel nodes after neo-adjuvant chemotherapy translate into a high local recurrence rate?

Prospective trials demonstrate that sentinel node (SN) biopsy after neo-adjuvant chemotherapy (NACT) has a significant false-negative rate (FNR) when only 1 or 2 SNs are removed. It is unknown whether this increased FNR correlates with an elevated risk of recurrence. Tumor Registry data at an NCI-Designated Comprehensive Cancer Center were reviewed from 2004 to 2018 for patients having a negative SN biopsy after NACT. Among 190 patients with histologically negative nodes after NACT having 1 (n = 42), 2 (n = 46), and ≥3 (n = 102) SNs, axillary recurrences occurred in 7.14%, 0%, and 1.96% (p = 0.09), breast recurrences occurred in 2.38%, 6.52%, and 0.98% (p = 0.12), and distance recurrences occurred in 16.67%, 8.70%, and 7.84% (p = 0.27), respectively. Time to first recurrence did not differ by SN count (p = 0.41). After adjustment for age, race, clinical stage, and receptor status, there were no differences in the rates of axillary (p = 0.26), breast (p = 0.44), or distance recurrence (p = 0.24) by numbers of SNs harvested. Median follow-up was 46.8 months. Despite higher post-NACT FNRs reported in randomized trials for patients having <3 sentinel nodes, recurrence rates were not significantly different for 1 versus 2 versus ≥3 SNs. This suggests that patients having 1 or 2 post-NACT SNs identified may not necessitate axillary dissection.

Robotic Inguinal Hernia Repair Outcomes: Operative Time and Cost Analysis.

BACKGROUND: Robotic inguinal hernia repair is the latest iteration of minimally invasive herniorrhaphy. Previous studies have shown expedited learning curves compared to traditional laparoscopy, which may be offset by higher cost and longer operative time. We sought to compare operative time and direct cost across the evolving surgical practice of 10 surgeons in our healthcare system. METHODS: This is a retrospective review of all transabdominal preperitoneal robotic inguinal hernia repairs performed by 10 general surgeons from July 2015 to September 2018. Patients requiring conversion to an open procedure or undergoing simultaneous procedures were excluded. The data was divided to compare each surgeon's initial 20 cases to their subsequent cases. Direct operative cost was calculated based on the sum of supplies used intra-operatively. Multivariate analysis, using a generalized estimating equation, was adjusted for laterality and resident involvement to evaluate outcomes. RESULTS: Robotic inguinal hernia repairs were divided into two groups: early experience (n = 167) and late experience (n = 262). The late experience had a shorter mean operative time by 17.6 min (confidence interval: 4.06 - 31.13, p = 0.011), a lower mean direct operative cost by $538.17 (confidence interval: 307.14 - 769.20, p < 0.0001), and fewer postoperative complications (p = 0.030) on multivariate analysis. Thirty-day readmission rates were similar between both groups. CONCLUSION: Increasing surgeon experience with robotic inguinal hernia repair is associated with a predictable reduction in operative time, complication rates, and direct operative cost per case. Thirty-day readmission rates are not affected by the learning curve.

Meaningful autonomy in general surgery training: Exploring for gender bias.

BACKGROUND: Resident autonomy is essential to the development of a surgical resident. This study aims to analyze gender differences in meaningful autonomy (MA) given to general surgery trainees intraoperatively. METHODS: This is a retrospective study of general surgery residents at an academic-affiliated tertiary care facility. Attending surgeons completed post-operative evaluations based on the Zwisch model (4-point scale, ≥3 indicating MA). RESULTS: Attending faculty members (37 males, 15 females) completed evaluations of 35 residents (18 males, 17 females). A total of 3574 evaluations were analyzed (1380 female, 2194 male residents) over 28 months. Multivariate analysis revealed case complexity, post graduate year level and rater gender were significantly associated with MA. Resident gender and faculty experience did not impact MA. CONCLUSIONS: In contrast to published literature, resident gender did not influence MA. This may be encouraging to surgical programs seeking strategies to address gender bias.

The role of 2-octyl cyanoacrylate in prevention of penile adhesions after circumcision: A prospective, randomized trial.

PURPOSE: Penile adhesions are the most common complication after circumcision, although strategies to decrease them are poorly studied. We conducted a prospective, randomized trial comparing the use of 2-octyl cyanoacrylate (glue) skin adhesive to hydrophobic ointment after circumcision. METHODS: Patients <7years old undergoing circumcision were randomized to glue around the sutures and corona of the penis or antibiotic ointment. The primary outcome variable was postoperative penile adhesions. Utilizing a power of 0.8 and an alpha of 0.05, 168 patients were calculated for each arm. Because of high attrition, we planned to include up to 500 patients. Presence/absence of adhesions was evaluated 2-4weeks postop. Parents subjectively scored happiness, comfort, distress, and concern on a Likert scale 1-5. RESULTS: From 11/2012 through 7/2016, 409 patients were enrolled. Adhesion data were available on 243 patients. There was no difference between glue (16.8%) and those with antibiotic ointment (15.2%) (p=0.88) or in parental satisfaction across all areas measured. 165 patients were lost to follow-up, evenly distributed between the two groups (38% vs. 42%, p=0.49). CONCLUSION: The placement of 2-octyl cyanoacrylate skin adhesive does not decrease the rate of postoperative penile adhesions after circumcision. Parent satisfaction outcomes are similar. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level II.

Inflammatory myofibroblastic tumors in children.

BACKGROUND: Inflammatory myofibroblastic tumor (IMFT) is an uncommon neoplasm in children. METHODS: Retrospective review from 1993 to 2014 of patients ≤18years of age with a histopathologic diagnosis of IMFT treated at two tertiary centers. RESULTS: Thirty-two patients were diagnosed with IMFT. Mean (±SD) age was 9.3±5.7years at diagnosis. Tumor location was variable: abdomen/pelvis (28%), head/neck region (22%), intrathoracic (22%), genitourinary (9%), bowel (6%) liver (6%), and musculoskeletal (6%). Median follow-up was 2.6±4.6years, with 3 recurrences and 2 deaths, which occurred only after recurrence. Positive microscopic margin after resection was associated with recurrence, compared to those that had a negative margin (40% vs. 0%, p=0.04). Recurrence was associated with increased mortality (67% vs 0%, p=0.01). Time from first symptoms to resection was shorter in those with recurrence (25.8±22 vs. 179±275days, p=0.01) and in nonsurvivors (44.0±8.0 vs. 194.3±53.4days, p=0.02). Adjuvant chemotherapy, not including steroid monotherapy, either given before or after resection, was administered more often to nonsurvivors (100% vs 4%, p=0.009), and use of corticosteroids was also higher in the nonsurvivors (100% vs. 15%, p=0.04). CONCLUSIONS: IMFT is a rare pediatric neoplasm with variable locations. Complete excision is critical for cure. Proposed guidelines for diagnosis, treatment and surveillance of theses tumors in children are reported.

Treatment of Idiopathic Achalasia in the Pediatric Population: A Systematic Review.

BACKGROUND: Achalasia is a rare idiopathic neuromuscular disorder of the esophagus, characterized as a syndrome of impaired relaxation of the lower esophageal sphincter and decreased peristalsis of the esophageal body. OBJECTIVE: The primary objective is to determine the best first-line treatment for pediatric achalasia based on the consolidation of the current literature that compares outcomes after pneumatic dilatation (PD) versus surgical myotomy (Heller esophagomyotomy [HM]). DATA SOURCES: A systematic review of English articles using OVID was performed. STUDY SELECTION: OVID was used to search for articles focusing on the treatment of pediatric esophageal achalasia with PD versus HM. DATA EXTRACTION: Independent extraction of data was performed by N.E.S using predefined data fields. DATA SYNTHESIS: Seven articles were included in the systematic review. Techniques of HM and PD varied widely. The best first-line treatment of pediatric achalasia was determined to be HM in two articles, PD in one article, and equal efficacy in one article. Three articles concluded that appropriate initial treatment was determined by the age of the child. CONCLUSION: Adequate comparative data are lacking to determine the ideal treatment of pediatric achalasia. Appropriately designed randomized controlled trials with long-term follow-up are needed to determine ideal treatment algorithms in pediatric achalasia.

The Role of Medication in Spontaneous Gastrocutaneous Fistula Closure.

PURPOSE: Factors precipitating persistence of gastrocutaneous fistulas (GCFs) are not clearly understood. The role of proton pump inhibitors (PPIs) or histamine receptor antagonists in GCF closure is not yet studied. We aimed to identify whether these medications influence spontaneous GCF closure. METHODS: Retrospective review was performed on children who underwent gastrostomy tube insertion and removal from January 2010 to February 2013. Spontaneous GCF closure rates and medication use during gastrostomy tube removal were investigated. RESULTS: Of the 97 patients included, 48 had spontaneous GCF closure, whereas 49 required operative closure. When comparing these two groups, no significant difference existed in spontaneous GCF closure rates among patients who were on ranitidine, PPIs, or both (p = 0.09, p = 0.83, p = 0.06 respectively). Spontaneous closure occurred more in older patients (2.7 ± 4.1 vs. 0.9 ± 1.6 years, p < 0.01) and in patients without fundoplication at time of tube insertion (12.5 vs. 30.6%, p = 0.05). There were more laparoscopic placements in the group that closed spontaneously (83 vs. 61%, p = 0.02). Mean gastrostomy tube presence was longer in patients who required surgery than those with spontaneous closures (18.7 ± 10.3 vs. 35.5 ± 36.6 months, p < 0.01). CONCLUSION: Ranitidine or PPI use upon removal of gastrostomy tubes does not seem to facilitate spontaneous GCF closure in children.

Pediatric Head Trauma.

Traumatic brain injury (TBI) refers to a spectrum of brain injury that can result in significant morbidity and mortality in pediatric patients. Pediatric head trauma is distinct from adult TBI. The purpose of this review article is to discuss pediatric TBI and current treatment modalities available.

Influence of body mass index on skin grafting in pediatric burns.

BACKGROUND: There is heterogeneous literature on the association of obese and underweight body habitus on burn outcomes in adult and pediatric literature. We examine the effect of standardized pediatric body mass index (BMI) categories skin graft utilisation. METHODS: A retrospective chart review was performed on children who underwent burn treatment from January 1995 to November 2011. BMI was categorized by standard definitions: underweight (<5%), normal (5-85%), overweight (85-95%), obese (>95%). RESULTS: There were 1164 patients: 77 underweight, 604 normal, 215 overweight, and 268 obese patients. No differences existed between group demographics. Grafts were performed in 39% of underweight, 27% of normal, 22% of overweight, and 27% of obese patients. Underweight children had nearly a 2 fold increase in their risk of full thickness burns and were 1.8 times more likely to undergo skin grafting than normal BMI children. Overweight children had a significant decrease in the incidence skin grafting by 23% then compared to normal weight children. There were no differences in percent TBSA burned or percent TBSA grafted using ANOVA. CONCLUSIONS: Underweight pediatric burn victims have an increased risk for skin grafting while mildly overweight children are slightly protected from skin grafting.

Lower radiation exposure from body CT imaging for trauma at a dedicated pediatric hospital.

PURPOSE: We compare radiation exposure from body CT imaging for blunt trauma performed at outside hospitals (OH) versus our children's hospital (CH). METHODS: We performed a retrospective chart review of all children transferred to our facility for management of trauma after undergoing a body CT scan at an OH from June 2011 to August 2013. Radiation from OH images was compared to our CH by matching to age, gender, and nearest date. Radiation measures included dose length product (DLP), computed tomography dose index (CTDI), and size-specific dose estimate (SSDE). RESULTS: Fifty-one children were transferred from 39 OH. Abdomen/pelvis and chest/abdomen/pelvis imaging was performed in 30 and 21 children, respectively. Demographics are shown in Table 1. Results are illustrated in Tables 2 and 3. Contrast was utilized in 45 (1 oral, 41 IV, 3 both) and 51 (49 IV, 2 both). CT scans were performed at OH and CH, respectively (P=0.03). CONCLUSIONS: Children receive significantly less radiation exposure with body CT imaging for blunt trauma when performed at our dedicated CH. CT scans were significantly more likely to be ordered with appropriate contrast at our CH.

Single-site Nissen fundoplication versus laparoscopic Nissen fundoplication.

BACKGROUND: Advances in minimally invasive surgery have led to the emergence of single-incision laparoscopic surgery (SILS). The purpose of this study is to assess the feasibility of SILS Nissen fundoplication and compare its outcomes with traditional laparoscopic Nissen fundoplication. METHODS: This is a retrospective study of 33 patients who underwent Nissen fundoplication between January 2009 and September 2010. RESULTS: There were 15 SILS and 18 traditional laparoscopic Nissen fundoplication procedures performed. The mean operative time was 129 and 182 minutes in the traditional laparoscopic and single-incision groups, respectively (P=.019). There were no conversions in the traditional laparoscopic group, whereas 6 of the 15 patients in the SILS group required conversion by insertion of 2 to 4 additional ports (P=.0004). At short-term follow-up, recurrence rates were similar between both groups. To date, there have been no reoperations. CONCLUSIONS: SILS Nissen fundoplication is both safe and feasible. Short-term outcomes are comparable with standard laparoscopic Nissen fundoplication. Challenges related to the single-incision Nissen fundoplication include overcoming the lengthy learning curve and decreasing the need for additional trocars.

Nursing preference of topical silver sulfadiazine versus collagenase ointment for treatment of partial thickness burns in children: survey follow-up of a prospective randomized trial.

We performed a nursing survey to inquire about nursing preferences toward the use of silver sulfadiazine (SSD) and collagenase (CO). We performed a survey between September 2012 and December 2012 asking nurses to rate the application/removal of both products and provide a description of their preferences. Ten study nurses (83%) preferred CO over SSD (P < .001). Two nurses (17%) had no preference. Negative comments on SSD were pseudoeschar (50%), difficult application burns (25%), messiness (67%), and increased number of dressing changes (25%). Negative comments on CO were the need for an additional antimicrobial agent (58%), although 1 nurse noted the higher expense with CO. Nurses preferred CO because of cleanliness of dressing (17%), lack of pseudoeschar (25%), and less pain with dressing changes (8%). Despite no difference in outcomes between SSD and CO, experienced burn nurses prefer CO because of perceptions of decreased trauma and frequency of dressing changes.

Radiation exposure from head computed tomography scans in pediatric trauma.

BACKGROUND: We have previously reported that children receive significantly less radiation exposure after abdominal and/or pelvis computed tomography (CT) scanning for acute appendicitis when performed at our children's hospital (CH) rather than at outside hospitals (OH). In this study, we compare the amount of radiation children receive from head CTs for trauma done at OH versus those at our CH. METHODS: A retrospective chart review was performed on all children transferred to our hospital after receiving a head CT for trauma at an OH between July 2012 and December 2012. These children were then blindly case matched based on date, age, and gender to children at our CH. RESULTS: There were 50 children who underwent head CT scans for trauma at 28 OH. There were 21 females and 29 males in each group. Average age was 7.01 ± 0.5 y at the OH and 7.14 ± 6.07 at our CH (P = 0.92). Average weight was 30.81 ± 4.69 kg at the OH and 32.69 ± 27.21 kg at our CH (P = 0.81). Radiation measures included dose length product (671.21 ± 22.6 mGycm at OH versus 786.28 ± 246.3 mGycm at CH, P = 0.11) and CT dose index (53.4 ± 2.26 mGy at OH versus 49.2 ± 12.94 mGy at CH, P = 0.56). CONCLUSIONS: There is no significant difference between radiation exposure secondary to head CTs for traumatic injuries performed at OH and those at a dedicated CH.

Fever after redo Nissen fundoplication with hiatal hernia repair.

BACKGROUND: Fevers often arise after redo fundoplication with hiatal hernia repair. We reviewed our experience to evaluate the yield of a fever work-up in this population. METHODS: We performed a retrospective review of children undergoing redo Nissen fundoplication with hiatal hernia repair between December 2001 and September 2012. Temperatures and fever evaluations of those children receiving a mesh repair were compared with those without mesh. A fever defined as temperature ≥38.4°C. RESULTS: Fifty one children received 46 laparoscopic, 4 open, and 1 laparoscopic converted to open procedures. Biosynthetic mesh was used in 25 children whereas 26 underwent repair without mesh. A fever occurred in 56% of those repaired with mesh compared with 23.1% without mesh (P = 0.02). A fever evaluation was conducted in 32% of those with mesh compared with 11.5% without mesh (P = 0.52). A urinary tract infection was identified in one child after mesh use and an infection was identified in two children without mesh, one pneumonia and one wound infection (P = 1). In those repaired with mesh, there was no significant difference in maximum temperature. CONCLUSIONS: Fever is common after redo Nissen fundoplication with hiatal hernia repair and occurs more frequently, and with higher temperatures in those with mesh. Fever work-up in these patients is unlikely to yield an infectious source and is attributed to the extensive dissection during the redo procedure.

Radiation exposure - how do CT scans for appendicitis compare between a free standing children's hospital and non-dedicated pediatric facilities?

BACKGROUND: We compare the amount of radiation children receive from CT scans performed at non-dedicated pediatric facilities (OH) versus those at a dedicated children's hospital (CH). METHODS: Using a retrospective chart review, all children undergoing CT scanning for appendicitis at an OH were compared to children undergoing CT imaging for appendicitis at a CH between January 2011 and November 2012. RESULTS: One hundred sixty-three children underwent CT scans at 42 different OH. Body mass index was similar between the two groups (21.00±6.49kg/m(2), 19.58±5.18kg/m(2), P=0.07). Dose length product (DLP) was 620±540.3 at OH and 253.78±211.08 at CH (P < 0.001). OH CT scans accurately diagnosed appendicitis in 81%, while CT scans at CH were accurate in 95% (P=0.026). CTDIvol was recorded in 65 patients with subset analysis showing CTDIvol of 16.98±15.58 and 4.89±2.64, a DLP of 586.25±521.59 and 143.54±41.19, and size-specific dose estimate (SSDE) of 26.71±23.1 and 3.81±2.02 at OH and CH, respectively (P<0.001). CONCLUSION: Using SSDE as a marker for radiation exposure, children received 86% less radiation and had improved diagnostic accuracy when CT scans are performed at a CH.
