RESUMEN
BACKGROUND: Acute appendicitis is one of the most common reasons for pediatric surgical consultation in the emergency room. Although acute appendicitis is a clinical diagnosis, the use of imaging in the emergency department to assist with the diagnosis is very common. Ultrasound is frequently utilized in pediatrics because of the radiation risks associated with computed tomography (CT) scan. The risks of radiation in the pediatric population are much more significant than in adults. Reasons for this include smaller size so there is a relative higher radiation dose than for larger adults, radiosensitive organs such as thyroid, bone marrow, and gonads, and radiation exposure earlier in life allows for more time that a radiation induced cancer could develop. The risks of radiation from imaging are increased with cumulative dosing. METHODS: The purpose of this study was to incorporate the pediatric appendicitis score (PAS) and standardized ultrasound scoring system to provide a combined score that would assist with the clinical diagnosis of acute appendicitis and avoid the need for a CT scan. RESULTS: The presented data shows that for scores of 7 or more, the specificity and sensitivity is 90% and 90.2%, respectively for the diagnosis of acute appendicitis. DISCUSSION: This study validates the combined score, shows the specific cutoffs, and initiates the discussion that CT scan may not always be required for diagnosing acute appendicitis if this scoring system is used.

Retroperitoneal abscesses are relatively uncommon in infants and children. They carry a high rate of morbidity due to insidious onset and pose a diagnostic challenge. Here we report a case of spontaneous retroperitoneal methicillin-resistant Staphylococcus aureus (MRSA) infection in a two-year-old patient. The patient was successfully treated with antibiotics and surgical washout and drainage. A retroperitoneal abscess is usually found in patients with a history of osteomyelitis, seeding of post-traumatic pelvic hematomas, post radiation, or perforated hollow viscus including but not limited to: perforated appendicitis, bowel perforations due to foreign objects or malignancy, or perforated diverticulitis. Most of these conditions are usually found in the adult population. As per a recent literature search, there are no reported cases of a spontaneous retroperitoneal MRSA abscess in the pediatric population without risk factors.
RESUMEN
INTRODUCTION: In response to the opioid epidemic, we hypothesized that adequate pain control can be achieved with few, if any, opioid prescriptions at discharge following pediatric surgical procedures. METHODS: All records for patients 0-15â¯years old who underwent pediatric surgical operations from December 2017 through May 2018 were reviewed. Opioids prescriptions, emergency department (ED) visits, and hospital readmissions were recorded. Postoperative pain was assessed on a scale from 0 to 10 via phone call within three days of discharge. RESULTS: 352 patients underwent 394 surgical procedures. Three patients were prescribed opioids at discharge. There were no pain-related readmissions. One patient returned to the ED owing to pain. 116 unique pain scores were obtained from 114 patients: score 0 (nâ¯=â¯69, 59%), 1-3 (nâ¯=â¯31, 27%), 4-5 (nâ¯=â¯11, 9%), 6-8 (nâ¯=â¯5, 4%), and 9-10 (nâ¯=â¯0, 0%). There was a positive association between pain and increasing age (râ¯=â¯0.26, pâ¯=â¯0.005). No patients who underwent hernia repair reported a pain score greater than 3. CONCLUSIONS: Adequate pain control at discharge after pediatric general surgical procedures can be achieved for most children with scheduled nonopioid medications only. A limited supply of opioids for analgesia after discharge may benefit small subset of patients. This strategy would help reduce opioid prevalence in the community. TYPE OF STUDY: Retrospective cohort study. LEVEL OF EVIDENCE: Level III.

The purpose of this study was to determine the changes in endothelin (ET) receptor subtype expression and their functional significance after endotoxin pretreatment. Rats were pretreated with lipopolysaccharide (LPS) or sterile saline (control). After 24 h, liver samples were homogenized and competitive receptor binding assays were performed. There was no significant difference in ET receptor binding affinity between the control and LPS groups. However, the receptor subtype density showed a significant increase in ET(B) receptors in LPS-treated rats, whereas the amount of ET(A) receptors was almost identical between the two groups. In control, almost all ET receptors (95%) were displaced by using combined ET(A) antagonist (BQ-610) and ET(B) agonist (IRL-1620) as competitors, whereas only 80% (P < 0.05 versus control) was displaced in LPS group, raising the possibility of novel type of ET receptor expression. An infusion of ET(B) agonist (Sarafotoxin 6c, S6c) through portal vein in isolated perfused livers produced the same pressure response in both LPS and control groups; however, the portal pressure increase in response to the ET-1, which binds all ET receptors, was significantly potentiated in LPS-treated rats compared to controls. We conclude that altered regulation of ET receptors, in particular, the appearance of ET binding capacity that is not displaced by ET(A) or ET(B) competitors, may explain the hyper-response of the portal venous system to ET-1 during endotoxemia.
