Rare case of pediatric trauma with hepatic injury managed using gel-foam embolization: a case report.

Nonoperative management for hepatic injuries requires observation and supportive care in the case of hemodynamically stable patients. If there is active bleeding on presentation, hepatic artery embolization is an option to achieve hemostasis in the acute setting. Although interventional radiology procedures are well documented in adults, there is limited literature regarding these procedures in the pediatric population. In this report, we present a case of a pediatric patient who sustained blunt abdominal trauma, resulting in a grade IV liver injury. Treatment involved fluoroscopically guided right hepatic segmental arterial gel-foam embolization.

Umbilical Fascial Defects are Common and Predict Trocar Site Hernias After Laparoscopic Appendectomy.

INTRODUCTION: Investigations have demonstrated that trocar site hernia (TSH) is an under-appreciated complication of laparoscopic surgery, occurring in as many as 31%. We determined the incidence of fascial defects prior to laparoscopic appendectomy and its impact relative to other risk factors upon the development of TSH. METHODS: TSH was defined as a fascial separation of ≥ 1 cm in the abdominal wall umbilical region on abdominal computerized tomography scan (CT) following laparoscopic appendectomy. Patients admitted to our medical center who had both a preoperative CT and postoperative CT for any reason (greater than 30 days after surgery) were reviewed for the presence of TSH from May 2010 to December 2018. CT scans were measured for fascial defects, while investigators were blinded to film timing (preoperative or postoperative) and patient identity. Demographic information was collected. RESULTS: 241 patients undergoing laparoscopic appendectomy had both preoperative and late postoperative CT. TSH was identified in 49 (20.3%) patients. Mean preoperative fascial gap was 3.3 ± 4.3 mm in those not developing a postoperative hernia versus 14.8 ± 7.3 mm in those with a postoperative hernia (P < .0001). Preoperative fascial defect on CT was predictive of TSH (P < .001, OR = 1.44), with an Area Under the Curve (AUC) of .921 (95%CI: .88-.92). Other major risk factors for TSH were: age greater than 59 years (P < .031, OR = 2.48); and obesity, BMI > 30 (P < .012, OR = 2.14). CONCLUSIONS: The incidence of trocar site hernia was one in five following laparoscopic appendectomy. The presence of a pre-existing fascial defect, advanced age, and obesity were strong predictors for the development of trocar site hernia.

Recurrent spontaneous small bowel perforations with a rare pathology: non-familial visceral myopathy.

Visceral myopathy is a rare, often misdiagnosed disease characterised by abnormalities in the gastrointestinal smooth muscle layer. Its clinical presentation includes pseudo-obstruction, intestinal dysmotility and spontaneous perforation. We report an atypical case of a 51-year-old man with a history of recurrent small bowel perforations who presented with an acute abdomen. A laparotomy was performed with identification of a distal jejunal perforation. A small bowel resection with end-to-end anastomosis was done. Minimal adhesions were seen intraoperatively despite the patient's multiple prior surgeries. Pathology showed histiocytic inflammation and patchy loss of the muscle layer reflective of visceral myopathy. Genetic testing revealed a variant of uncertain significance in the myosin light chain kinase gene. It is difficult to make a conclusive diagnosis given the patient's clinical presentation closely mimicking other gastrointestinal disorders. However, it is crucial to consider visceral myopathy in patients with recurrent spontaneous intestinal perforations as a differential diagnosis.

Equity on the frontlines of trauma surgery: An #EAST4ALL roundtable.

BACKGROUND: Inequity exists in surgical training and the workplace. The Eastern Association for the Surgery of Trauma (EAST) Equity, Quality, and Inclusion in Trauma Surgery Ad Hoc Task Force (EAST4ALL) sought to raise awareness and provide resources to combat these inequities. METHODS: A study was conducted of EAST members to ascertain areas of inequity and lack of inclusion. Specific problems and barriers were identified that hindered inclusion. Toolkits were developed as resources for individuals and institutions to address and overcome these barriers. RESULTS: Four key areas were identified: (1) harassment and discrimination, (2) gender pay gap or parity, (3) implicit bias and microaggressions, and (4) call-out culture. A diverse panel of seven surgeons with experience in overcoming these barriers either on a personal level or as a chief or chair of surgery was formed. Four scenarios based on these key areas were proposed to the panelists, who then modeled responses as allies. CONCLUSION: Despite perceived progress in addressing discrimination and inequity, residents and faculty continue to encounter barriers at the workplace at levels today similar to those decades ago. Action is needed to address inequities and lack of inclusion in acute care surgery. The EAST is working on fostering a culture that minimizes bias and recognizes and addresses systemic inequities, and has provided toolkits to support these goals. Together, we can create a better future for all of us.

Putting a halt to unnecessary transfers: Do patients with isolated subarachnoid hemorrhage and Glasgow Coma Scale of 13 to 15 need a trauma center?

OBJECTIVES: Trauma patients with isolated subarachnoid hemorrhage (iSAH) presenting to nontrauma centers are typically transferred to an institution with neurosurgical availability. However, recent studies suggest that iSAH is a benign clinical entity with an excellent prognosis. This investigation aims to evaluate the neurosurgical outcomes of traumatic iSAH with Glasgow Coma Scale (GCS) of 13 to 15 who were transferred to a higher level of care. METHODS: The American College of Surgeon Trauma Quality Improvement Program was retrospectively analyzed from 2010 to 2015 for transferred patients 16 years and older with blunt trauma, iSAH, and GCS of 13 or greater. Those with any other body region Abbreviated Injury Scale of 3 or greater, positive or unknown alcohol/drug status, and requiring mechanical ventilation were excluded. The primary outcome was need for neurosurgical intervention (i.e., intracranial monitor or craniotomy/craniectomy). RESULTS: A total of 11,380 patients with blunt trauma, iSAH, and GCS of 13 to 15 were transferred to an American College of Surgeon level I/II from 2010 to 2015. These patients were 65 years and older (median, 72 [interquartile range (IQR), 59-81]) and white (83%) and had one or more comorbidities (72%). Eighteen percent reported a bleeding diathesis/chronic anticoagulation on admission. Most patients had fallen (80%), had a GCS of 15 (84%), and were mildly injured (median Injury Severity Score, 9 [IQR, 5-14]). Only 1.7% required neurosurgical intervention with 55% of patients being admitted to the intensive care unit for a median of 2 days (IQR, 1-3 days). Furthermore, 2.2% of the patients died. The median hospital length of stay was only 3 days (IQR, 2-5 days), and the most common discharge location was home with self-care (62%). Patient factors favoring neurosurgical intervention included high Injury Severity Score, low GCS, and chronic anticoagulation. CONCLUSION: Trauma patients transferred for iSAH with GCS of 13 to 15 are at very low risk for requiring neurosurgical intervention. LEVEL OF EVIDENCE: Therapeutic/care management, Level IV.

Transcriptional regulation of an axonemal central apparatus gene, sperm-associated antigen 6, by a SRY-related high mobility group transcription factor, S-SOX5.

SOX5 is a transcription factor with homology to the high mobility group box region of the testis-determining factor, SRY. Both the mouse and human SOX5 genes encode a 48-kDa SOX5 protein (S-SOX5) that is only present in tissues containing cells with motile cilia/flagella. The mammalian sperm-associated antigen 6 gene (SPAG6) encodes an axoneme central apparatus protein. Because human and mouse SPAG6 gene promoters contain multiple potential binding sites for SOX5, SPAG6 gene regulation by S-SOX5 was investigated in BEAS-2B cells, a line derived from human bronchial cells. Like FOXJ1, a transcription factor known to be essential for motile ciliogenesis, S-SOX5 stimulated mouse and human SPAG6 promoter function in BEAS-2B cells, but the effect was abrogated when the SOX5 binding sites were mutated or deleted. S-SOX5 and FOXJ1 functioned cooperatively in stimulating SPAG6 promoter activity. The SPAG6 message was up-regulated when S-SOX5 was overexpressed in BEAS-2B cells, and silencing of S-SOX5 by RNA interference down-regulated SPAG6 transcripts. Chromatin immunoprecipitation and EMSA experiments demonstrated that S-SOX5 associates with the SPAG6 promoter directly. The present study demonstrates that SPAG6 is a S-SOX5 target gene, indicating a key role for S-SOX5 in the formation and function of motile cilia.
