A New Era in Medical Information: ChatGPT Outperforms Medical Information Provided by Online Information Sheets About Congenital Malformations.

BACKGROUND: ChatGPT has demonstrated notable capabilities and has gained popularity in various medical tasks, including patient education. This study evaluates the content and readability of ChatGPT's responses to parents' questions about congenital anomalies. METHODS: Information on four congenital anomalies (congenital diaphragmatic hernia, esophageal atresia and tracheoesophageal fistula, anorectal malformation, and gastroschisis) was assessed. Seven questions frequently asked by parents were posed for each anomaly, and responses generated by GPT-4 were compared to online information sheets from three top pediatric medical centers. Two senior pediatric surgeons, blinded to the source, evaluated the answers based on accuracy, comprehensiveness, and conciseness. Reading time and readability of the answers were also assessed. RESULTS: ChatGPT answered all 28 questions, while online information sheets varied in completeness. ChatGPT's responses were rated significantly higher regarding full accuracy, comprehensiveness, and conciseness compared to the online information sheets (p < 0.00001, <0.00001, 0.0002, respectively). Despite having longer reading times and more challenging to read, ChatGPT's responses were more precise and detailed. CONCLUSIONS: ChatGPT outperforms online information sheets in providing accurate, comprehensive, and concise answers about congenital anomalies. This positions ChatGPT as a beneficial supplementary resource in pediatric healthcare. Future research should explore real-world applications and usability among parents. LEVEL OF EVIDENCE: Level III.

Percutaneous core needle biopsy of neuroblastoma in the pediatric population: what have we learned in the last decade.

INTRODUCTION: Historically, neuroblastoma has been diagnosed by surgical open biopsy (SB). In recent decades, core needle biopsy (CNB) has replaced surgical biopsy due to its safe and adequate method of obtaining tissue diagnosis. AIM: Our study aimed to assess the effectiveness of CNB in obtaining tissue diagnosis for neuroblastoma and evaluate its safety profile in terms of post-operative complications, in comparison to SB. METHODS: A retrospective cohort study, including all patients younger than 18 years who were diagnosed with neuroblastoma from 2012 until 2022 in a single tertiary medical center. Patients' demographics, tumor size and location, pathological results, and clinical outcomes were collected. RESULTS: 79 patients were included in our study: 35 biopsies were obtained using image-guided CNB and 44 using SB. Patients' and tumor characteristics including age, gender, tumor volume, and stage were similar in both groups. The biopsy adequacy rate in the CNB group was 91% and 3 patients in this group underwent repeated biopsy. The safety profile in the CNB group was similar to the SB group. CONCLUSIONS: CNB is a safe method and should be considered the first choice for obtaining tissue diagnosis when feasible due to its high adequacy in terms of tumor histopathological features.

Antibiotic Treatment in Complicated Appendicitis: Can It Be Optimized?

BACKGROUND: The management of complicated appendicitis is inconclusive. Guidelines have not been established for the use of personalized antibiotic treatment. OBJECTIVES: To investigate specific risk factors to consider during the initial first-choice antibiotic therapy in children with complicated appendicitis. METHODS: This study included all pediatric patients younger than 18 years of age who underwent a laparoscopic appendectomy during 2012-2022 at a single tertiary medical center. RESULTS: In total, 300 pediatric patients underwent laparoscopic appendectomy due to complicated appendicitis. The patients were treated with ceftriaxone + metronidazole (CM). For 57 (19%) patients, the empirical treatment was changed to tazobactam/piperacillin (TP) due to resistant bacteria or clinical deterioration. The presence of generalized peritonitis during surgery and C-reactive protein (CRP) levels above 20 mg/L at admission were identified as risk factors for changing the antibiotic regimen from CM to TP. CONCLUSIONS: Generalized peritonitis and CRP > 20 gr/L were highly correlated with changing the antibiotic regimen to TP. For such patients, initial treatment with TP may result in clinical improvement and shorter hospitalization.

Negative appendectomy rate in the pediatric population: can we reach near-zero rates? An observational study.

INTRODUCTION: Correct diagnosis of acute appendicitis may sometimes be challenging. The Negative appendectomy rate (NAR) has declined in the recent years in Europe and USA, in part due to better diagnostic imaging tools. The aim of this study was to examine the rates of negative appendectomy in our institution, investigate trends in its incidence, and identify possible predicting factors. METHODS: A retrospective cohort study, including all patients younger than 18 years of age who underwent an appendectomy between 2007 and 2021 in a single tertiary medical center. Data regarding patient's demographics, laboratory and imaging results, pathological results and clinical outcome were collected. RESULTS: Between 2007 and 2021, a total of 3937 pediatric patients underwent appendectomy due to a working diagnosis of acute appendicitis. Overall, 143 patients (3.6%) had normal appendix on pathological examination. However, in the last 5 years, the rate of normal appendix was 1.9%, together with an increased rate of pre-operative imaging (from 40% to nearly 100%). CONCLUSION: Low NAR under 2% is an achievable benchmark in the era of accessible pre-operative imaging. In unequivocal cases, a secondary survey that includes repeated physical examination, blood work and imaging is recommended and may result in near-zero rates of NAR.

Recurrence rates following ileo-colic resection in pediatric patients with Crohn's disease.

BACKGROUND: Ileo-colic resection (ICR) is an important therapeutic option for Crohn's disease (CD) patients. There are limited updated data of clinical and endoscopic post-operative recurrence (POR) in pediatric patients with CD for the long run. We aimed to determine recurrence rates following ICR over an extended period of time and asses its risk factors. METHODS: This is a single-center retrospective review of 35 patients with CD between the ages of 6 and 17.9 years who required ICR between 2003 and 2021 at Schneider Children Medical Center of Israel. Medical charts were reviewed at different time-points post-ICR. RESULTS: Clinical recurrence following ICR was demonstrated in only 11.4% and 28.6% (n = 4, n = 10) in the first two and five years-much lower rates than what was reported so far. We found no specific risk factor that correlated with clinical recurrence, although patients that were treated with early prophylaxis of anti-TNF medications following ICR tend to have less recurrence. CONCLUSIONS: We found lower POR following ICR, especially in the first years after surgery-which can be attributed to close surveillance and early medical treatment. Such surveillance seems to improve recurrence rates in the first years following ICR.

Synchronous Malignancies Identified by PET-CT Scan in Breast Cancer Patients.

Breast cancer is a common malignancy and a common cause of cancer-related mortality in women. Pre-treatment workup of breast cancer does not routinely include positron emission tomography scans. We aimed to review cases of women with breast cancer and a synchronous second primary malignancy. We present three cases of women with non-metastatic cancer in whom a synchronous second primary malignancy was found. Synchronous, second primary malignancies which were identified included rectal cancer, gastrointestinal stromal tumor, and non-small cell lung cancer. All second primary malignancies were identified by a PET-CT scan. In conclusion, PET-CT may be used for detection of secondary primary malignancies in select breast cancer patients.

Biliary Tract Instrumentations Prior to Elective Cholecystectomy: Effect on Biliary Microbiome.

Background: Calculus biliary disease is a common condition that requires invasive procedures in complicated cases. The effect of biliary instrumentation on the biliary microbiome and its impact on surgical complications after elective cholecystectomy remains unclear. This study aimed to assess the impact of prior biliary instrumentation on the biliary microbiome, as well as on the clinical outcomes of cholecystectomy. Patients and Methods: This retrospective study included all patients who underwent elective cholecystectomy for calculus biliary disease between 2015 and 2020 in a single medical center. Data regarding biliary instrumentation prior to cholecystectomy, biliary cultures obtained during cholecystectomy, and clinical outcomes were collected. A comparison between patients with and without prior instrumentation was performed with regard to biliary cultures and clinical outcomes. Results: Of the 508 patients studied, 109 patients underwent biliary instrumentation prior to cholecystectomy. Patients with prior instrumentation were older and more likely to be men (p < 0.0001). Prior instrumentation was also associated with higher rates of conversion to open surgery (p < 0.0001). Positive biliary cultures and polymicrobial growth were both more common among patients with prior instrumentation (p < 0.0001). Prior instrumentation was associated with longer length of hospital stay, as well as higher rates of perioperative complications and surgical site infection (p < 0.0001). Conclusions: Prior instrumentation was associated with poorer clinical outcomes and affected the biliary microbiome. The different results of biliary cultures in these patients may suggest that an alternative empiric antibiotic regimen should be considered when treating patients with biliary instrumentation.

Does Maternal Omega 3 Supplementation Protect Against Infantile Hypertrophic Pyloric Stenosis?

OBJECTIVES: Infantile hypertrophic pyloric stenosis (IHPS) is potentially life threatening. The etiology of IHPS remains unknown and many risk factors have been reported. We aimed to assess the prevalence of known risk factors and investigate maternal nutrition and habits as possible additional risk factors for IHPS. METHODS: This case-control study includes mothers of infants diagnosed with IHPS and control mothers of infants, age 2 to 11 months, hospitalized in the pediatric department due to other conditions. Cases of IHPS were identified by review of all infants diagnosed with IHPS and operated upon in 2010 to 2016 at 2 major hospitals in central Israel. Data regarding potential risk factors were collected via questionnaires in both study groups. RESULTS: Sixty-six cases and 67 controls were included in the study. Maternal omega 3 supplement consumption during pregnancy was significantly less common among cases of IHPS as compared with controls (P = 0.031). Consumption of omega 3 supplement was defined as consumption of at least 1 to 2 per week during the pregnancy period. Following adjustment for known risk factors, including male sex and maternal smoking, maternal omega 3 supplement consumption remained associated with a significantly lower risk of developing IHPS (odds ratio = 0.303, 95% confidence interval 0.111-0.828, P = 0.02). CONCLUSIONS: Maternal omega 3 supplement consumption during pregnancy was associated with a significantly reduced risk of IHPS. Further studies are needed to support these results and investigate possible mechanisms of the effect of omega 3.
