The Great Mimicker: Secondary Syphilis-Associated Nephrotic Syndrome in an Adolescent Patient.

BACKGROUND: Syphilis is long regarded as the "great mimicker" for its variety of symptoms and clinical manifestations. Rarely, it can present with renal involvement, particularly nephrotic syndrome. This is an uncommon initial presentation, particularly in pediatrics. CASE REPORT: We present the case of a 17-year-old male adolescent who presented to the emergency department with a chief symptom of abdominal pain. In addition, he was found to have a number of stigmata characteristic of both syphilis and nephrotic syndrome, including a rash and diffuse edema, particularly in the lower extremities. This led to the diagnosis of nephrotic syndrome secondary to syphilis infection. Prompt diagnosis and treatment of syphilis resulted in resolution of both kidney injury and symptoms of the underlying infection. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the variety of manifestations of sexually transmitted infections, particularly in the pediatric population. It demonstrates how identifying syphilis as the inciting event led to the correct treatment management for the patient. This presentation serves to teach and remind emergency physicians of the wide-ranging presentations for sexually transmitted infections, particularly syphilis, and the necessity of obtaining a sexual history even in adolescent patients.

Detecting pediatric wrist fractures using deep-learning-based object detection.

BACKGROUND: Missed fractures are the leading cause of diagnostic error in the emergency department, and fractures of pediatric bones, particularly subtle wrist fractures, can be misidentified because of their varying characteristics and responses to injury. OBJECTIVE: This study evaluated the utility of an object detection deep learning framework for classifying pediatric wrist fractures as positive or negative for fracture, including subtle buckle fractures of the distal radius, and evaluated the performance of this algorithm as augmentation to trainee radiograph interpretation. MATERIALS AND METHODS: We obtained 395 posteroanterior wrist radiographs from unique pediatric patients (65% positive for fracture, 30% positive for distal radial buckle fracture) and divided them into train (n = 229), tune (n = 41) and test (n = 125) sets. We trained a Faster R-CNN (region-based convolutional neural network) deep learning object-detection model. Two pediatric and two radiology residents evaluated radiographs initially without the artificial intelligence (AI) assistance, and then subsequently with access to the bounding box generated by the Faster R-CNN model. RESULTS: The Faster R-CNN model demonstrated an area under the curve (AUC) of 0.92 (95% confidence interval [CI] 0.87-0.97), accuracy of 88% (n = 110/125; 95% CI 81-93%), sensitivity of 88% (n = 70/80; 95% CI 78-94%) and specificity of 89% (n = 40/45, 95% CI 76-96%) in identifying any fracture and identified 90% of buckle fractures (n = 35/39, 95% CI 76-97%). Access to Faster R-CNN model predictions significantly improved average resident accuracy from 80 to 93% in detecting any fracture (P < 0.001) and from 69 to 92% in detecting buckle fracture (P < 0.001). After accessing AI predictions, residents significantly outperformed AI in cases of disagreement (73% resident correct vs. 27% AI, P = 0.002). CONCLUSION: An object-detection-based deep learning approach trained with only a few hundred examples identified radiographs containing pediatric wrist fractures with high accuracy. Access to model predictions significantly improved resident accuracy in diagnosing these fractures.

Effect of a positive pressure ventilation-refresher program on ventilation skill performance during simulated newborn resuscitation.

AIM: Clinical staff highly proficient in neonatal resuscitation are essential to ensure prompt, effective positive pressure ventilation (PPV) for infants that do not breathe spontaneously after birth. However, it is well-documented that resuscitation competency is transient after standard training. We hypothesized that brief, repeated PPV psychomotor skill refresher training would improve PPV performance for newborn care nurses. METHODS: Subjects completed a blinded baseline and post PPV-skills assessment. Data on volume and rate for each ventilation was recorded. After baseline assessment, subjects completed PPV-Refreshers over 3 months consisting of psychomotor skill training using a newborn manikin with visual feedback. Subjects provided PPV until they could deliver ≥30 s of PPV meeting targets for volume (10-21 mL) and rate (40-60 ventilations per minute [vpm]). Baseline and post assessments were compared for total number PPV delivered, number target PPV delivered (volume 10-21 mL), mean volume and mean rate (Wilcoxon signed-rank test, median[IQR]). RESULTS: Twenty-six subjects were enrolled and completed a baseline assessment; 24 (92%) completed a post-assessment; 2 (8%) were lost to follow-up. Over 3 months, a mean 3.2 (range 1-6) PPV-Refreshers/subject were completed. Compared to baseline, subjects demonstrated significant improvement for total (57 [36-74] vs. 33 [26-46]; p = 0.0007) and target PPV (23 [13-23] vs. 11 [5-21]; p = 0.024), and a significant change in mean volume (mL) (11.5 [10.2-13] vs. 13.4 [11-16]; p = 0.02) and mean rate (vpm) (54 [45-61] vs. 40 [28-49]; p = 0.019). CONCLUSIONS: A PPV-Refresher program with brief, repeated psychomotor skill practice significantly improved PPV performance with the greatest improvement in total PPV and target PPV. Additional investigation is warranted to determine optimal PPV-Refresher frequency.Registered at ClinicalTrials.gov #NCT02347241.

The NICU Cuddler Curriculum: A Service-Learning Curriculum for Preclinical Medical Students in the Neonatal Intensive Care Unit.

Introduction: The neonatal intensive care unit (NICU) is often seen as off-limits by preclinical medical students. The NICU cuddler curriculum is a service-learning curriculum that invited preclinical medical students into the NICU to engage with and learn from one of the hospital's most vulnerable populations: neonates. The purpose of this preclinical experience was to provide students with exposure to the NICU and an opportunity to engage with babies, families, and the NICU staff, in order to improve students' clinical and communication skills. Methods: First- and second- year medical students applied and were selected for participation. Participants cuddled neonates in the NICU for at least 10 hours, attended didactic sessions relevant to neonatal care, and debriefed with an attending each semester. The curriculum was evaluated via qualitative analysis and postparticipation surveys. Results: To date, a total of 73 students have participated in the NICU cuddler curriculum. Qualitative analysis revealed students felt included in patient care, empowered in their understanding of the social determinants of health, and useful in their role. A postsurvey of clinical medical students following participation revealed the sustained impact of this program. Discussion: This service-learning curriculum for preclinical medical students has the potential to enhance student understanding of the social determinants of health, increase exposure to the NICU, and promote interprofessional collaboration, ultimately increasing preparedness of students for their clinical years.

Use of esophageal balloon manometry in the management of pediatric acute respiratory distress syndrome.

There is paucity of literature regarding the use of esophageal balloon manometry in the management of Pediatric Acute Respiratory Distress Syndrome. We describe our first ever experience of successful usage of esophageal balloon pressure manometry in a child with acute respiratory distress syndrome. This is a six-year-old girl who presented with shortness of breath and fever and was found to be in severe acute respiratory distress syndrome due to septic shock secondary to group A streptococcus. The patient was managed using an esophageal balloon manometry for positive end-expiratory pressure titration. She was liberated from invasive mechanical ventilation on day 7 of hospital course. Esophageal balloon manometry guided positive end-expiratory pressure for 103 out of 155 hours of ventilation with no obvious sequelae. Our case shows the feasibility of transpulmonary pressure measurements in pediatric patients. This practice may be useful to optimize management in pediatric acute respiratory distress syndrome to improve outcomes.

Incidence and characteristics of positive pressure ventilation delivered to newborns in a US tertiary academic hospital.

INTRODUCTION: The Neonatal Resuscitation Program (NRP) guidelines recommend positive pressure ventilation (PPV) in the first 60s of life to support perinatal transition in non-breathing newborns. Our aim was to describe the incidence and characteristics of newborn PPV using real-time observation in the delivery unit. METHODS: Prospective, observational, quality improvement study conducted at a tertiary academic hospital. Deliveries during randomized weekday/evening 8-h shifts were attended by a trained observer. Intervention data were recorded for all newborns with gestational age (GA) ≥34wks that received PPV. Descriptive summaries and Kruskal-Wallis test for continuous variables and Fisher's exact test for categorical variables were used to compare characteristics. RESULTS: Of 1135 live deliveries directly observed over 18mos, 64 (6%) newborns with a mean GA 39±2wks received PPV: Median time from birth to warmer was 20s (IQR 15-22s); PPV was initiated within 60s of life in 29 (45%) and between 60 and 90s of life in 17 (27%). PPV duration was <120s in 38 (60%). Seven/21 (33%) newborns that received PPV after vaginal delivery were not pre-identified and resuscitation team was alerted after delivery. We found no association between PPV start time and duration of PPV (p=0.86). CONCLUSION: We observed that most (94%) term newborns spontaneously initiate respirations. In over half observed deliveries receiving PPV, time to initiation of PPV was greater than 60s (longer than recommended). Compliance with current NRP guidelines is difficult, and it's not clear whether it is the recommendations or the training to achieve PPV recommendations that should be modified.
