Misplaced Evidence, Missed Opportunities: Protocols for Handling Ballistic Evidence in Pediatric Patients.

BACKGROUND: Gun-related injury is now the number one cause of death in pediatric trauma patients. Many hospitals lack dedicated forensic nurses or updated protocols for handling ballistic evidence. Evidence not collected, handled improperly, or misplaced may deny a victim the basic human right to justice. OBJECTIVE: This article aims to describe an initiative to highlight the importance of proper management of ballistic evidence and to educate medical providers on best practices for the documentation, handling, removal, and transfer of ballistic evidence. METHODS: After discovering 24 "orphaned" bullets and bullet fragments in our hospital that had not been turned over to law enforcement, we sought to turn in evidence to the proper authorities and implement protocols to prevent this error in the future. New protocols were written by forensic staff, and education on new protocols was provided via in-person training, grand rounds, emails, and other collaborative initiatives. RESULTS: Evidence was matched to police reports using the patient name and date of birth on evidence labels. The median (interquartile range [IQR]) time of lost ballistic evidence was 1,397 (903, 1604) days, with the oldest bullet removed in 2015. All bullets were successfully returned to law enforcement with a median (IQR) time from bullet discovery to collection of 78 (78, 174) days. CONCLUSIONS: Ballistic evidence handling protocols are essential for all hospitals. Dedicated, trained forensic staff should be employed to ensure proper evidence handling.

Revisiting the prevalence of nonclassic congenital adrenal hyperplasia in US Ashkenazi Jews and Caucasians.

PurposeNonclassic 21-hydroxylase deficiency, a mild form of congenital adrenal hyperplasia (CAH), is estimated to be the most common autosomal recessive condition, with an especially high prevalence in Ashkenazi Jews (3.7% affected, 30.9% carriers), based on a 1985 HLA-B linkage study of affected families. Affected individuals, especially women, may suffer from hyperandrogenism and infertility. State-of-the-art genetic studies have not been done to confirm these remarkable rates.MethodsCYP21A2 genotyping was performed in 200 unrelated healthy Ashkenazi Jewish subjects and 200 random US Caucasians who did not self-identify as a specific ethnicity using multiplex minisequencing, real-time polymerase chain reaction and junction site analysis.ResultsNonclassic CAH carriership was found similarly in 15% (95% confidence interval (CI): 10.4-20.7) of Ashkenazi Jews and 9.5% (95% CI: 5.8-14.4) of Caucasians (P=0.13). The proportion of Ashkenazi Jewish nonclassic CAH carriers (0.15 versus 0.309, P<0.0001) and disease affected (0.005 versus 0.037, P=0.009) was not as high as previously reported. The estimated prevalence of nonclassic CAH in Caucasians was 1 in 200 (0.5%, 95% CI: 0.01-2.8).ConclusionNonclassic CAH is a common condition, regardless of ethnicity, and should be considered with preconception and infertility counseling.

Androgens correlate with increased erythropoiesis in women with congenital adrenal hyperplasia.

OBJECTIVE: Hyperandrogenism in congenital adrenal hyperplasia (CAH) provides an in vivo model for exploring the effect of androgens on erythropoiesis in women. We investigated the association of androgens with haemoglobin (Hb) and haematocrit (Hct) in women with CAH. DESIGN: Cross-validation study. PATIENTS: Women with CAH from Sheffield Teaching Hospitals, UK (cohort 1, the training set: n = 23) and National Institutes of Health, USA (cohort 2, the validation set: n = 53). MEASUREMENTS: Androgens, full blood count and basic biochemistry, all measured on the same day. Demographic and anthropometric data. RESULTS: Significant age-adjusted correlations (P < 0·001) were observed for Ln testosterone with Hb and Hct in cohorts 1 and 2 (Hb r = 0·712 & 0·524 and Hct r = 0·705 & 0·466), which remained significant after adjustments for CAH status, glucocorticoid treatment dose and serum creatinine. In the combined cohorts, Hb correlated with androstenedione (P = 0·002) and 17-hydroxyprogesterone (P = 0·008). Hb and Hct were significantly higher in cohort 1 than those in cohort 2, while there were no group differences in androgen levels, glucocorticoid treatment dose or body mass index. In both cohorts, women with Hb and Hct in the highest tertile had significantly higher testosterone levels than women with Hb and Hct in the lowest tertile. CONCLUSIONS: In women with CAH, erythropoiesis may be driven by androgens and could be considered a biomarker for disease control.

Acute Exercise Improves Prefrontal Cortex but not Hippocampal Function in Healthy Adults.

The effects of acute aerobic exercise on cognitive functions in humans have been the subject of much investigation; however, these studies are limited by several factors, including a lack of randomized controlled designs, focus on only a single cognitive function, and testing during or shortly after exercise. Using a randomized controlled design, the present study asked how a single bout of aerobic exercise affects a range of frontal- and medial temporal lobe-dependent cognitive functions and how long these effects last. We randomly assigned 85 subjects to either a vigorous intensity acute aerobic exercise group or a video watching control group. All subjects completed a battery of cognitive tasks both before and 30, 60, 90, or 120 min after the intervention. This battery included the Hopkins Verbal Learning Test-Revised, the Modified Benton Visual Retention Test, the Stroop Color and Word Test, the Symbol Digit Modalities Test, the Digit Span Test, the Trail Making Test, and the Controlled Oral Word Association Test. Based on these measures, composite scores were formed to independently assess prefrontal cortex- and hippocampal-dependent cognition. A three-way mixed Analysis of Variance was used to determine whether differences existed between groups in the change in cognitive function from pre- to post-intervention testing. Acute exercise improved prefrontal cortex- but not hippocampal-dependent functioning, with no differences found between delay groups. Vigorous acute aerobic exercise has beneficial effects on prefrontal cortex-dependent cognition and these effects can last for up to 2 hr after exercise.

Establishing Shock Index, Pediatric Age-Adjusted (SIPA) Cut Points in Trauma Patients Under 1 Year of Age.

PURPOSE: Shock Index (SI) is used to predict injury severity and adverse outcomes in trauma patients, but age-adjusted shock index (SIPA) has superior performance in pediatric patients over the age of 1 year. SIPA scores under the age of 1 have not been well studied. This project aimed to establish and evaluate SIPA cut point data points for patients under 1 year of age. METHODS: Using age-based vital signs, we developed cut point values for patients under 1 year old using our institutional trauma data. All trauma patients under the age of 12 months were included, and clinical outcomes were recorded. SIPA cut points were defined using age specific vital sign limits (SIPA-VS) and tested against optimal cut points defined by ROC analysis (SIPA-ROC) and a cut point of 1.2 (SIPA-Nordin), which is used for patients ages 1-4 years. Student's t-test, chi-square tests, ANOVA, and test characteristics were used to analyze groups. RESULTS: A total of 609 pediatric trauma patients under the age of 12 months were identified from 2018 to 2022. SIPA scores were calculated for 483 patients. There were 406 patients with blunt trauma and 17 with penetrating. SIPA-Nordin was elevated in 81.6% (n = 397) of patients, compared to SIPA-VS 21% (n = 101) and SIPA-ROC 31% (n = 150). In comparison to SIPA-Nordin, both SIPA-VS and SIPA-ROC score exhibited superior specificity and negative predictive values (NPV) for multiple outcomes. Elevated SIPA-ROC scores had statistically significant associations with ICU admission, mechanical ventilation, severe anemia, transfusion during hospital admission, and in-hospital mortality. CONCLUSION: SIPA is a useful tool in identifying patients at risk for several complications of severe traumatic injury. SIPA cut points had high NPV and specificity for many outcomes. This study proposes cut point values that may aid in clinical decision-making for trauma patients under 1 year of age.Level of Evidence: Level IV Retrospective Review.

11-Oxygenated Androgens Are Biomarkers of Adrenal Volume and Testicular Adrenal Rest Tumors in 21-Hydroxylase Deficiency.

Context: Patients with 21-hydroxylase deficiency (21OHD) have long-term complications, resulting from poor disease control and/or glucocorticoid overtreatment. Lack of optimal biomarkers has made it challenging to tailor therapy and predict long-term outcomes. Objective: To identify biomarkers of disease control and long-term complications in 21OHD. Setting and Participants: Cross-sectional study of 114 patients (70 males), ages 2 to 67 years (median, 15 years), seen in a tertiary referral center. Methods: We correlated a mass-spectrometry panel of 23 steroids, obtained before first morning medication, with bone age advancement (children), adrenal volume (adults), testicular adrenal rest tumors (TART), hirsutism, menstrual disorders, and pituitary hormones. Results: Total adrenal volume correlated positively with 18 steroids, most prominently 21-deoxycortisol and four 11-oxygenated-C19 (11oxC19) steroids: 11ß-hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11ketoA4), 11ß-hydroxytestosterone (11OHT), and 11-ketotestosterone (11ketoT) (r ≈ 0.7, P < 0.0001). Nine steroids were significantly higher (P ≤ 0.01) in males with TART compared with those without TART, including 11OHA4 (6.8-fold), 11OHT (4.9-fold), 11ketoT (3.6-fold), 11ketoA4 (3.3-fold), and pregnenolone sulfate (PregS; 4.8-fold). PregS (28.5-fold) and 17-hydroxypregnenolone sulfate (19-fold) levels were higher (P < 0.01) in postpubertal females with menstrual disorders. In males, testosterone levels correlated positively with all 11oxC19 steroids in Tanner stages 1 and 2 (r ≈ 0.7; P < 0.001) but negatively in Tanner stage 5 (r = -0.3 and P < 0.05 for 11ketoA4 and 11ketoT). In females, testosterone level correlated positively with all four 11oxC19 steroids across all Tanner stages (r ≈ 0.8; P < 0.0001). Conclusion: 11oxC19 steroids and PregS might serve as clinically useful biomarkers of disease control and long-term complications in 21OHD.

Positive fertility outcomes in a female with classic congenital adrenal hyperplasia following bilateral adrenalectomy.

BACKGROUND: Classic congenital adrenal hyperplasia (CAH) requires lifetime steroid replacement and supraphysiologic glucocorticoid dose is often required for adequate adrenal androgen suppression. Patients often suffer from long-term co-morbidities and female infertility is common. CASE PRESENTATION: We report the use of laparoscopic bilateral adrenalectomy as a treatment for a 21 year old female with classic simple virilizing CAH and infertility. She presented as an adolescent with increasing weight gain, amenorrhea and elevated adrenal androgens despite the use of dexamethasone (250 mcg given twice daily), and fludrocortisone (150 mcg daily). An anti-androgen (flutamide 250 mg given twice daily) and a combined oral contraceptive pill were added to her regimen and prevented progressive virilization, but she eventually desired fertility. A bilateral laparoscopic adrenalectomy was performed at age 21. The right adrenal gland weighed 41.8 grams and the left gland 45.5 grams. There were no complications during the surgery. Since the surgery, she has had a total of three pregnancies, resulting in 3 healthy full-term infants. Follow-up 7 years later at age 27 revealed overall excellent health with a BMI of 25.1 kg/m(2), no evidence of adrenal rest tissue based on hormonal testing, above average quality-of-life based on 36-item short-form health survey and she has not experienced an adrenal crisis. CONCLUSIONS: This case highlights the use of bilateral adrenalectomy as a treatment option for female infertility in a patient with classic CAH and difficult-to-control hyperandrogenism secondary to adrenal nodular hyperplasia. Outstanding quality-of-life, disease control and fertility were achieved.
