ABSTRACT
Ultrasound-guided vascular access is a medical procedure that is becoming increasingly common in daily practice and is recommended to avoid iatrogenic complications. One of the procedures with a high-risk rate of complications is the vascular puncture. However, training on this technique can be challenging due to the limited availability of simulation models. We propose a simple, cost-effective, and effective ultrasound-guided vascular access simulation model that utilizes chicken breast and a urine catheter to address this need.
ABSTRACT
Background: Most studies have demonstrated the high accuracy of ultrasound for the diagnosis of acute appendicitis (AA) in children. However, the lack of visualization of the appendix on ultrasound is usually a challenge. The aim of this study was to identify any factors that might help the physician make the right decision when dealing with a child with suspected appendicitis and an appendix not seen on ultrasound. Patients and Methods: After receiving Institutional Review Board approval, we conducted a prospective study in a pediatric emergency department from January 1, 2022, to December 31, 2022. All children under 14 years of age with suspected AA and an appendix not visualized on ultrasound were included. Results: During the study period, 333 children presented with suspected AA. Of these patients, 106 had an appendix not seen on ultrasound. Our patients' median age was 10 years (interquartile range [IQR], 8-11 years), with 54.7% (n = 58) of children being female. Twenty-five (23.6%) were ultimately diagnosed with AA based on pathologic examination. Multivariable logistic regression analysis revealed that Alvarado score ≥6 and increased peri-appendiceal fat echogenicity were predictive for AA. The combination of these two factors provided a positive predictive value of 100%. A white blood cell (WBC) count ≤10 × 109/L and/or a C-reactive protein (CRP) level ≤6 mg/L makes the diagnosis of appendicitis unlikely. Conclusions: In conclusion, our study demonstrated that an Alvarado score at or above six and increased peri-appendiceal fat echogenicity are independent predictive factors of AA in children with non-visualized appendix on ultrasound. The combination of these two factors would confirm the diagnosis of AA in these patients.

Background: Intra-amniotic umbilical vein varices are characterized by a focal dilatation of the extra abdominal umbilical vein. Case report: We report a full-term baby female with extra-abdominal umbilical vein varices misdiagnosed clinically as an omphalocele. The umbilical vein was ligated and excised near the level of the liver. The infant died one day after surgery due to extrinsic compression of the renal pedicle by a massive thrombus, resulting in severe renal failure and life-threatening hyperkalemia despite intensive resuscitation. Conclusion: Large intra-amniotic umbilical vein varices can be clinically misdiagnosed as an omphalocele. Their resection near the level of the fascia, as with normal umbilical veins, could be a better management with a better prognosis.

Background: Breast phyllodes tumor has a distinct histologic appearance. There are no pediatric phyllodes tumors of the bladder in English literature reported. Case report: A 2-year-old boy presented with a urinary infection and obstructive urinary symptoms. A 3-cm slow-growing bladder mass revealed by repeated transabdominal ultrasonography was initially considered a ureterocele. Cystoscopic and laparoscopic exploration using pneumovesicum confirmed the diagnosis of a bladder neck tumor. Histologically, the features were of a benign phyllodes tumor, morphologically similar to those seen in breast tissue. The patient received no further treatment and showed no recurrence or metastasis. Conclusion: Phyllodes tumor can cause a pediatric bladder tumor.

Background: Despite the high prevalence of acute appendicitis in children and substantial resource utilization associated with this condition, no consensus has been reached on optimal timing for performing appendectomies. The aim of this study was to examine the association between time to appendectomy and outcomes and assess the feasibility of delayed appendectomy in children. Patients and Methods: We performed a retrospective analysis of all patients younger than 14 years of age undergoing an appendectomy for suspected appendicitis. We divided our patients into two groups based on whether their time to appendectomy was shorter or longer than eight hours: group A, early appendectomy and group B, delayed appendectomy. Then we compared the two study groups regarding demographic, clinical, and radiographic characteristics, peri-operative data, and outcomes. Results: During the eight-year study period, a total of 1,141 patients underwent appendectomies. After applying exclusion criteria, 852 children were included: 544 (63.8%) in group A and 308 (36.2%) in group B. There were no differences in the rate of complicated appendicitis at exploration, post-operative complications, length of post-operative hospital stay, and 30-day re-admission rate between the two study groups. Conclusions: Our study demonstrated that delaying appendectomy within 24 hours of presentation is safe and feasible for pediatric acute appendicitis. Therefore, patients presenting during nighttime hours could be initially treated conservatively with antibiotic agents. This allows the surgeon to delay surgery to the following day.

OBJECTIVE: The aim of the study was to assess the feasibility and outcomes of pediatric urological laparoendoscopic single-site (LESS) surgery. MATERIALS AND METHODS: We retrospectively collected charts of all patients who underwent LESS procedures in our department from January 2013 to December 2016. Data included demographic characteristics, type of procedures, intraoperative details, hospital stay, and complications. The umbilicus was used as the surgical site in all cases. All procedures were performed with a homemade glove port and standard straight 3- or 5-mm laparoscopic instruments. RESULTS: Seventy-three patients (55 males, 18 females) were identifed. Procedures included 46 orchidop-exies, 21 pyeloplasties, 8 varicocelectomies, 3 nephrecto-mies, 3 nephroureterectomies, 3 orchiectomies, and 1 renal hydatid cyst treatment. Median operative time for the entire cohort was 47 min (range 26-156 min). There was no signifcant intraoperative blood loss. No conversion to conventional laparoscopy or open surgery was needed. All patients required paracetamol postoperatively. The mean follow-up was 18 months. Two patients had testicular atrophy after a Fowler-Stephens procedure and 1 patient had testicular reascension. Cosmetic results were excellent. Forty-five (62.5%) patients were discharged on the day of surgery. CONCLUSION: Our study demonstrated that LESS surgery using our glove port technique and conventional laparoscopic instruments is a feasible and safe technique for the surgical management of various pediatric urological conditions.
ABSTRACT
BACKGROUND: Enterobius vermicularis (EV) is the most common helminthic infection in the world. This small parasite is predominant in the pediatric population. The presence of EV in the appendix can cause or mimick appendicitis. The aim of our study was to compare patients with EV infection and those without EV infection, and to identify predictive factors that may help the diagnosis of EV infection in patients presenting with right iliac fossa pain and avoid negative appendectomy. METHODS: A retrospective analysis of all the appendices removed between January 2012 and December 2016 was conducted at the department of pediatric surgery, Hedi Chaker Hospital, Sfax, Tunisia. According to the final histopathological diagnosis, patients with EV infection were compared to those without EV infection. Data including age, sex, white blood cell (WBC) count, neutrophil count, eosinophil count, C-reactive protein, and ultrasound results for both groups were analyzed and compared. The study protocol was approved by the local hospital ethics committee. Statistical analysis was performed using IBM SPSS, version 20. Descriptive analysis in the form of mean and standard deviation was performed on demographic information. Differences between groups were assessed using the student t-test for continuous variables and the χ2 test and Fisher exact test where appropriate for categorical variables. RESULTS: In total, 540 pediatric appendectomies were performed. Overall, 63.5% of patients were male and 36.5% were female. Mean age was 9.28 ± 2.77 years. 22.2% of procedures were completed laparoscopically, 76.5% were open and 1.3% were converted. The negative appendectomy rate was 11.1%. EV was present in 9.8% of cases. Comparison of clinical, biological, and ultrasound findings between two groups of patients with EV (EV+) and those without EV (EV-) shows a statistical significance for pruritus ani (P < 0.001), WBC count (P < 0.001), neutrophil count (P < 0.001), C-reactive protein (CRP) (P = 0.001), positive ultrasound (P < 0.001), perforation rate (P = 0.009), and negative appendectomy rate (P < 0.001). No significant difference between the two groups was seen when comparing gender (P = 0.271), vomiting (P = 0.130), eosinophil count (P = 0.915), and procedure (P = 0.536). CONCLUSION: EV was seen in 9.8% of pediatric appendectomies in our study. Pruritus ani, normal WBC count, normal neutrophil count, and normal CRP level at presentation could predict EV infection in children who present with right iliac fossa pain.

Totally implanted port devices are important for the administration of fluid and chemotherapeutic agents. However, their use may be associated with serious complications, such as catheter fracture and embolism. Most data on port catheter embolization consist of isolated case reports. We report a 6-year-old boy with relapse of an acute lymphoblastic leukemia. He presented with dysfunction of his totally implanted port device. Radiologic examination revealed a catheter fracture. Echocardiography showed the catheter embolized into the right ventricle. The catheter was successfully removed from the right ventricle by percutaneous endovascular intervention. During the procedure, it was observed that the catheter fragment was located in the pulmonary artery. Catheter embolism may go undiagnosed for a prolonged period; however, severe systemic clinical signs may develop. Any implanted catheter should be removed after completion of treatment, or should be checked regularly for this complication by periodic standard chest x-ray monitoring.
