RESUMO
Objective Untreated primary hyperparathyroidism (PHPT) has wide-ranging multisystemic effects. Recent studies based in the US have shown a less than 25% screening rate for PHPT. Our study aims to detect whether similar deficiencies exist in our community healthcare system while quantifying the prevalence of PHPT underdiagnosis and inadequate surgical referrals. Study design This retrospective quantitative study enrolled patients aged ≥18 years with imaged-confirmed nephrolithiasis at our healthcare facilities from 2017 to the present (n=2021). Patients with documented calcium levels and kidney/ureter stones were included. Descriptive and univariate analyses were performed. Results A total of 2021 subjects met the criteria to be enrolled in the study. 26.6% (n=537) of patients with nephrolithiasis had elevated calcium levels on record. 13.6% (n=73) of hypercalcemic patients were screened for PHPT with an intact parathyroid hormone (PTH). A majority (63%, n=46) of patients with intact PTH had PHPT defined as PTH levels >55 pg/mL. Ultimately, only 19.6% (n=9) of patients with PHPT were referred for surgical intervention, and there was no significant difference in referral rate between patients with PHPT and those without (p=0.913). Conclusions PHPT is underdiagnosed in our community, leading to a significantly low rate of surgical referral and delay in management. Implementation of hospital protocols to aid in improving diagnosis and interventions could improve outcomes for PHPT patients.
RESUMO
INTRODUCTION: Ewing sarcoma (EWS) is a highly malignant tumor of bone and soft tissue that occasionally arises from viscera. Visceral EWS (V-EWS) is challenging to manage given its varied organ distribution and often late-stage presentation. We aimed to characterize our institutional experience with V-EWS, focusing on its surgical management, and to compare V-EWS outcomes against those with osseous (O-EWS) and soft tissue EWS (ST-EWS). METHODS: Retrospective review of all EWS patients ≤21 years presenting to a single institution between 2000 and 2022. Patient- and disease-specific characteristics were compared. Overall and relapse-free survival were estimated using Kaplan Meier methods and log-rank test. RESULTS: 156 EWS patients were identified: 117 O-EWS, 20 ST-EWS, and 19 V-EWS. V-EWS arose in the kidney (n = 5), lung (n = 5), intestine (n = 2), esophagus (n = 1), liver (n = 1), pancreas (n = 1), adrenal gland (n = 1), vagina (n = 1), brain (n = 1), and spinal cord (n = 1). No significant demographic differences were detected between EWS groups. V-EWS was more frequently metastatic at presentation (63.2%; p = 0.005), yet no significant overall or relapse-free survival differences emerged between EWS groups, with similar follow-up intervals. While V-EWS required multiple unique operative strategies to gain primary control, no significant difference in treatment strategies appeared between groups. Surgery-only primary control was associated with improved overall and relapse-free survival in all groups. CONCLUSIONS: V-EWS presents unique management challenges in children and adolescents given its variable sites of origin. This large cohort is the first to describe the surgical management and outcomes of V-EWS, demonstrating more frequent metastatic presentation, while achieving similar survival across groups. LEVEL OF EVIDENCE: Level 2 - Cohort Study.

OBJECTIVE: Pediatric spinal injuries in all-terrain vehicle (ATV) and dirt bike crashes are relatively uncommon but may be associated with significant morbidity. There are no recent studies examining these injuries, their management, and outcomes. Therefore, a retrospective study was performed to characterize pediatric spinal injuries related to ATV and dirt bike crashes over the last decade. METHODS: Data on all patients involved in ATV or dirt bike crashes evaluated at a regional level 1 pediatric trauma center over a 10-year period (2010-2019) were analyzed. Descriptive statistics were analyzed and chi-square, Fisher exact, and Mann-Whitney U-tests were performed comparing the demographics, injury characteristics, and clinical outcomes in patients with versus those without spinal injuries. RESULTS: Of 680 patients evaluated, 35 (5.1%) were diagnosed with spinal injuries. Over the study period, both spinal injuries and emergency department visits related to ATV or dirt bike crashes increased in frequency. All spinal injuries were initially diagnosed on CT scans, and 57.9% underwent spinal MRI. Injuries were most commonly thoracic (50%), followed by cervical (36.8%). The injuries of most patients were classified as American Spinal Injury Association (ASIA) grade E on presentation (86.8%), while 2 (5.3%) had complete spinal cord injuries (ASIA grade A) and 3 patients (8.6%) were ASIA grade B-D. Operative management was required for 13 patients (28.9%). Nonoperative management was used in 71.1% of injuries, including bracing in 33% of all injuries. Patients with spinal injuries were older than those without (13.4 ± 3.35 vs 11.5 ± 3.79 years, p = 0.003). Spinal injuries occurred via similar crash mechanisms (p = 0.48) and in similar locations (p = 0.29) to nonspinal injuries. Patients with spinal injuries more frequently required admission to the intensive care unit (ICU; 34.2% vs 14.6%, p = 0.011) and had longer hospital stays (mean 4.7 ± 5.5 vs 2.7 ± 4.0 days, p = 0.0025). CONCLUSIONS: Although infrequent among young ATV and dirt bike riders, spinal injuries are associated with longer hospital stays, increased ICU use, and required operative intervention in 29%. Increasing awareness among ATV and dirt bike riders about the severity of riding-related injuries may encourage safer riding behaviors.
RESUMO
BACKGROUND: Few consensus statements exist to guide the timely diagnosis and management of urine leaks in children sustaining blunt renal trauma (BRT). The aims of this study were to characterize kidney injuries among children who sustain BRT, evaluate risk factors for urine leaks, and describe the negative impact of urinoma on patient outcomes and resource consumption. METHODS: A retrospective review was performed of 347 patients, younger than 19 years, who presented with BRT to a single American College of Surgeons-verified Level I Pediatric Trauma Center between 2005 and 2020. Frequency of and risk factors for urine leak after BRT were evaluated, and impact on patient outcomes and resource utilization were analyzed. RESULTS: In total, 44 (12.7%) patients developed urine leaks, which exclusively presented among injury Grade 3 (n = 5; 11.4%), Grade 4 (n = 27; 61.4%), and Grade 5 (n = 12; 27.3%). A minority of urine leaks (n = 20; 45.5%) were discovered on presenting CT scan but all within 3 days. Kidney-specific operative procedures (nephrectomy, cystoscopy with J/ureteral stent, percutaneous nephrostomy) were more common among urine leak patients (n = 17; 38.6%) compared with patients without urine leaks (n = 3; 1.0%; p = 0.001). Patients with urine leak had more frequent febrile episodes during hospital stay (n = 24; 54.5%; p = 0.001) and showed increased overall 90-day readmission rates (n = 14; 33.3%; p < 0.001). Independent risk factors that associated with urine leak were higher grade (odds ratio [OR], 7.9; 95% confidence interval [CI], 2.6-24.3; p < 0.001), upper-lateral quadrant injuries (OR, 2.9; 95% CI, 1.2-7.1; p = 0.02), and isolated BRT (OR, 2.6; 95% CI, 1.0-6.5; p = 0.04). CONCLUSION: In a large cohort of children sustaining BRT, urine leaks result in considerable morbidity, including more febrile episodes, greater 90-day readmission rates, and increased operative or image-guided procedures. This study is the first to examine the relationship between kidney quadrant injury and urine leaks. Higher grade (Grade 4-5) injury, upper lateral quadrant location, and isolated BRT were independently predictive of urine leaks. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

To assess causal association of depression with subclinical coronary atherosclerosis, we performed computer-based and manual search of literature for studies which had assessed relationship of depression disorder with coronary atherosclerosis. All studies had diagnosed depression with validated tools in patients without diagnosed coronary artery disease. The Bradford Hill criteria of cause-effect association was consistently fulfilled by those studies which achieved statistical significance and further showed incremental strength of association with one or more of the following attributes: (1) prospective cohort study, met cause-effect criteria of "temporality"; (2) relatively severe and/or longer period of depression, met cause-effect criteria of "dose-response"; (3) depression with predominantly somatic symptoms cluster, met cause-effect criteria of "scientific plausibility"; (4) multiethnic larger sample, met cause-effect criteria of "population equivalence"; and (5) multicenter study, met criteria of "environmental equivalence." Our results show that there is a significant association of depression with coronary atherosclerosis at its subclinical stages.

BACKGROUND: Diaphragm paralysis (DP) complicates the postoperative course of neonates and infants undergoing cardiac surgery. Events causing DP remain poorly understood, and preventive strategies remain elusive. This retrospective cohort analysis aims to test the hypothesis that chest tubes in contact with the phrenic nerve in the pleural apex may cause pressure palsy. METHODS: In late 2018, the chest tube positioning strategy was changed so as to avoid a putative "danger zone" configuration, defined as (1) the chest tube looping apicomedially at the level of the second right intercostal space, and (2) wedging of chest tube tip against pericardium. A preintervention and postintervention analysis of 531 patients from 2012 to 2019 was performed to evaluate any association of chest tube position or duration in place with DP. Univariable and multivariable analyses were carried out, with significance set a priori at P < .05. RESULTS: The preintervention group comprised 488 patients, of whom 32 (6.6%) had RDP. The postintervention group comprised 43 patients, none of whom had DP. Multivariable analysis of the entire cohort revealed chest tube positioning in the danger zone as the only significant association with RDP (odds ratio, 4.22; 95% confidence interval, 1.57-11.33; P < .05). CONCLUSIONS: Chest tubes that occupy the right superior pleural space are associated with increased risk of DP.

BACKGROUND: Aortic arch reobstruction is a common complication after aortic repair, with rates of reintervention varying from 0% to 40%, depending on the disease and the institution. This study aimed to determine the reintervention rate in children undergoing aortic arch repair using a tailored autologous pericardial patch at our center (Monroe Carell, Jr Children's Hospital at Vanderbilt, Nashville, TN). METHODS: This retrospective study examined all patients operated on by a single surgeon for aortic arch reconstruction through sternotomy, from 2011 to 2018, with 1 year of follow-up. Our data set was analyzed for normality by using the Shapiro-Wilk test, and nonparametric statistical methods were used. Kaplan-Meier survival analysis was performed, IBM SPSS software version 23 was used to perform all statistical analysis. RESULTS: A total of 171 patients met inclusion criteria. Twenty-three (13.5%) patients underwent aortic arch reinterventions during the study period, 17 (9.9%) catheter based and 3 (1.8%) surgical. Three patients (1.8%) had both. Freedom from reintervention at 1-year follow-up for the univentricular and biventricular patients was 82.1% and 89.4% (P = .174), respectively. To assess the growth of the aortic arch over time, cardiac catheterization measurements were used to index different parts of the aortic arch against the descending aorta. Ascending-to-descending aortic arch measurements revealed that the pre-Glenn median was 2.0 (interquartile range, 1.8 to 2.2), whereas the pre-Fontan median was 2.5 (interquartile range, 2.2 to 2.7) (P < .05). CONCLUSIONS: There was no significant difference in reintervention rates between biventricular and univentricular arches, and catheterization measurements showed significant growth of the arch over time. The use of a tailored autologous pericardial patch for aortic arch repair is comparable to other reported methods of arch repair.

Percutaneous coronary intervention (PCI) is the preferred treatment for acute coronary syndrome (ACS) secondary to atherosclerotic coronary artery disease. This nonsurgical procedure is also used for selective patients with stable angina. Although the procedure is essential for restoring blood flow, reperfusion can increase oxidative stress as a side effect. We address whether intravenous infusion of vitamin C (VC) prior to PCI provides a benefit for cardioprotection. A total of eight randomized controlled trials (RCT) reported in the literature were selected from 371 publications through systematic literature searches in six electronic databases. The data of VC effect on cardiac injury biomarkers and cardiac function were extracted from these trials adding up to a total of 1185 patients. VC administration reduced cardiac injury as measured by troponin and CK-MB elevations, along with increased antioxidant reservoir, reduced reactive oxygen species (ROS) and decreased inflammatory markers. Improvement of the left ventricular ejection fraction (LVEF) and telediastolic left ventricular volume (TLVV) showed a trend but inconclusive association with VC. Intravenous infusion of VC before PCI may serve as an effective method for cardioprotection against reperfusion injury.

OBJECTIVES: Infants undergoing congenital heart surgery require central venous lines which can be achieved by various combinations of transthoracic lines, percutaneous-indwelling central catheters and tunneled Broviac catheters. Transthoracic lines are removed by protocol prior to cardiac intensive care unit discharge (risk of bleeding), at which time percutaneous-indwelling central catheters are placed. Transdiaphragmatic tunneled Broviac catheters placed at the time of sternotomy, remain in place until hospital discharge, when they are safely removed at bedside. We characterized actual cost profiles associated with strategies that do versus do not include tunneled Broviac catheters. METHODS: From January 2014 to December 2016, we identified a study population of 220 consecutive patients under 1 year of age undergoing congenital heart surgery. Cost data were acquired from our electronic patient system interface database and office of finance. Our cohort was divided into 2 groups, tunneled Broviac catheter and nontunneled Broviac catheter. We calculated the total cost associated with each groups' central venous lines, propensity matched, and used the Mann-Whitney U test to analyze the results. RESULTS: Eighty-three (37.7%) of the 220 patients had tunneled Broviac catheters. The tunneled Broviac catheter group had 4 percutaneous-indwelling central catheter insertions and 6 radiological interventions while the nontunneled Broviac catheter group had 90 percutaneous-indwelling central catheters and 203 radiologic interventions. After propensity score matching, both groups were reduced to 82 patients and sum, median and interquartile range cost for tunneled Broviac catheters and nontunneled Broviac catheters was $17,351.84, $159.76 (128-159.76) versus $72,809.32, $1277.26 (31.76-1277.26), P < .02 respectively. CONCLUSIONS: Tunneled Broviac catheters, placed routinely at cardiac surgery, incur lower costs than the conventional combination of transthoracic lines and percutaneous-indwelling central catheters. The cost-effectiveness is achieved by reducing the number of percutaneous-indwelling central catheters and associated radiologic interventions.

BACKGROUND: A shift in the healthcare system towards the centralization of common yet costly surgeries, such as total hip arthroplasty (THA), to high-volume centers of excellence, is an attempt to control the economic burden while simultaneously enhancing patient outcomes. The "volume-outcome" relationship suggests that hospitals performing more treatment of a given type exhibit better outcomes than hospitals performing fewer. This theory has surfaced as an important factor in determining patient outcomes following THA. We performed a systematic review with meta-analyses to review the available evidence on the impact of hospital volume on outcomes of THA. MATERIALS AND METHODS: We conducted a review of PubMed (MEDLINE), OVID MEDLINE, Google Scholar, and Cochrane library of studies reporting the impact of hospital volume on THA. The studies were evaluated as per the inclusion and exclusion criteria. A total of 44 studies were included in the review. We accessed pooled data using random-effect meta-analysis. RESULTS: Results of the meta-analyses show that low-volume hospitals were associated with a higher rate of surgical site infections (1.25 [1.01, 1.55]), longer length of stay (RR, 0.83[0.48-1.18]), increased cost of surgery (3.44, [2.57, 4.30]), 90-day complications (RR, 1.80[1.50-2.17]) and 30-day (RR, 2.33[1.27-4.28]), 90-day (RR, 1.26[1.05-1.51]), and 1-year mortality rates (RR, 2.26[1.32-3.88]) when compared to high-volume hospitals following THA. Except for two prospective studies, all were retrospective observational studies. CONCLUSIONS: These findings demonstrate superior outcomes following THA in high-volume hospitals. Together with the reduced cost of the surgical procedure, fewer complications may contribute to saving considerable opportunity costs annually. However, a need to define objective volume-thresholds with stronger evidence would be required. TRIAL REGISTRATION: PROSPERO CRD42019123776.
