Abstract
Objective Geriatric patients have more complicated appendicitis, which leads to higher morbidity and mortality rates. Sarcopenia has been shown to have a negative impact on patients undergoing surgery. This study aims to reveal the predictive value of computerized tomography-assessed (CT-assessed) sarcopenia for complicated appendicitis in geriatric patients. Methods One-hundred fifty-four patients' with acute appendicitis age, gender, co-morbidities, appendicitis status, and body mass index (BMI) values were analyzed. The skeletal muscle index (SMI) and related measurements were evaluated. Results Fifty-two percent of the patients had complicated, and 48% had uncomplicated appendicitis. There was a statistically significant difference between uncomplicated and complicated cases regarding BMI, SMI, and muscle area values (P < 0.05). The cutoff point by Receiver Operating Characteristic Curve analysis was conducted for SMI and showed 71% sensitivity and 52% specificity (P = 0.042). Multivariate analysis has shown that comorbidities are significantly more associated with complicated appendicitis than sarcopenia. Conclusion Geriatric patients with lower BMI, decreased muscle area, and CT-detected sarcopenia have an increased risk of complicated appendicitis. Comorbidities are also important risk factors. Surgeons should be aware of factors leading to complicated appendicitis, which may cause higher morbidity and mortality rates in elderly patients.

Abstract
Perforated viscus is a fatal condition associated with a high mortality rate that necessitating immediate management. In gastric cancer, perforation is a relatively late rare presentation. In this study, we report a case of a 40-year-old male who presented with perforated gastric cancer. In the emergency department (ED), the provisional diagnosis was septic peritonitis and shock. However, upon exploratory laparotomy, pyloric tumor was detected metastasizing to the duodenum, liver, and porta hepatis.

Abstract
BACKGROUND The American Association for the Surgery of Trauma (AAST) appendicitis severity grading criteria use independent subscales for radiologists (Rad), surgeons (Surg), and pathologists (Path). We reviewed the EAST Multicenter Study of the Treatment of Appendicitis in America: Acute, Perforated, and Gangrenous (MUSTANG) database to determine rates of discordance and clinical consequences of inaccuracy. MATERIALS AND METHODS A confusion matrix was constructed for pairs among Rad, Surg, and Path. Accuracy was reported using chronologically latest diagnosis as gold standard. "Concordance" (C) was achieved when both agreed on the severity grade and "Discordance"(D) when they disagreed. A composite endpoint("COMP"= 30-d incidence of surgical site infection, abscess, wound complication, Clavien-Dindo complication, secondary intervention, ED[Emergency Department] visit, hospital readmission, and mortality) was compared between C versus D groups via χ2 test with Bonferroni correction to define statistical significance(P = 0.05/9 = 0.005). RESULTS For each pair and diagnosis, subjects were categorized as C or D and compared for the incidence of COMP. Incidence of COMP for Surg and/or Path in C versus D: 16% versus. 26% (p = 0.006, NS by Bonferroni) for acute (A), 39% versus 33% (p = 0.39) for gangrenous (G), and 48% versus 37% (p = 0.035, NS by Bonferroni) for perforated (P). For Rad and/or Path in C versus. D: 17% versus 42% (p < 0.001) for A, 27% versus 31% (p = 0.95) for G, and 56% versus 48% (p = 0.48) for P. For C versus D: 17% versus 40% (p < 0.001) for A, 36% versus 26% (p = 0.43) for G, and 51% versus 39% (p = 0.29) for P. CONCLUSIONS In appendicitis treated by appendectomy, surgeons are most accurate at diagnosing acute appendicitis and least accurate at diagnosing gangrenous. Radiologists are less accurate for all categories. When the surgeon is wrong, clinical outcomes are not significantly worse. However, when the radiologist is wrong about acute appendicitis, patients have worse clinical outcomes.

Abstract
Background: The corona virus disease of 2019 (COVID-19) imposed new public health constraints that deterred people from coming to the hospital. The outcome of patients who developed appendicitis during mandated COVID-19 quarantine has yet to be examined. The main objective was to establish whether there was an increased rate of perforated appendicitis seen during COVID-19 quarantine. Secondary objectives included observing the type of procedure performed, length of stay, and associated complications. Materials and Methods: This retrospective analysis was designed to look at the rates of appendicitis and perforated appendicitis observed during mandatory "safer at home order" from March to May 2020. The same time period a year earlier was used for comparative analysis. The study utilized data gathered from a single health care system, which consisted of a large regional referral center with three emergency rooms (ERs). Patients were included in the study if they presented to any ER in our health care system with a chief complaint of acute appendicitis. Perforated appendicitis was determined either radiographically or intraoperatively. Interventions included surgery, percutaneous drainage, or medical management. Results: There were 107 patients who were included. During quarantine, a total of 48 patients presented with acute appendicitis, with 16 perforations, compared with the previous year where 59 patients presented with acute appendicitis, with 10 perforations (33% versus 17% P = .04). Most patients underwent laparoscopic appendectomy (91%, n = 98), six patients (6%) were managed with intravenous antibiotics and 3 patients (3%) with percutaneous drainage. Patients who perforated had a longer duration of symptoms (2 versus 1, P = .03), white blood cell count (13,190 versus 15,960 cells/mm3, P = .09), and longer operative time (72 versus 89 minutes, P = .01). Patients who perforated had an increased length of stay and rate of complication. Conclusion: There was an overall increased rate of perforated appendicitis seen during quarantine compared with the previous year. Patients with perforated appendicitis had an increased length of stay, longer operative time, and increased rate of complications. Thus, although people were staying home due to public health safety orders, it negatively impacted those who developed appendicitis who may have presented to the hospital otherwise sooner.

Abstract
Background: Association between time-to-appendectomy and clinical outcomes is controversial with conflicting data regarding risk of perforation. The purpose of this study was to explore the associations between in-hospital delay in treatment of simple appendicitis with the incidence of complicated appendicitis discovered at appendectomy. Methods: The Eastern Association for the Surgery of Trauma (EAST) Multicenter Study of the Treatment of Appendicitis in America: Acute, Perforated, and Gangrenous (MUSTANG) database was queried and patients with acute appendicitis diagnosed on imaging were included. Upgrade was defined as gangrenous or perforated finding at appendectomy. Time intervals from emergency department (ED) triage to appendectomy were recorded in six-hour groups. Upgrade percentage for each group was presented and rates of a composite end point (30-day incidence of surgical site infection, abscess, wound complication, Clavien-Dindo complication, secondary intervention, ED visit, hospital re-admission, and mortality) were compared with Bonferroni correction to determine statistical significance (p = 0.05/9 = 0.005). Results: Of 3,004 included subjects, 484 (16%) experienced upgrade at appendectomy. Upgrade rates (%, 95% confidence interval [CI]) were: group 0-6 hours, 17% (95% CI, 14-19); group 6-11 hours, 15% (95% CI, 13-17%); group 12-17 hours, 16% (95% CI, 13-19); group 18-23 hours, 17% (95% CI, 12-23); group 24-29 hours, 30% (95% CI, 20-43); and group 30+ hours, 24% (95% CI, 14-37) (p = 0.014, NS by Bonferroni). Of 484 subjects with upgrade, 200 (41%; 95% CI, 37-46) had a worse composite outcome compared with 518 (21%; CI, 19-22) of 2,520 subjects with no upgrade (p < 0.001). The upgrade group was older (49 ± 17 years vs 39 ± 16 years), had a higher Charlson comorbidity index (CCI; 1.6 ± 1.9 vs 0.7 ± 1.4) and was more likely to have positive smoking history (20% vs 14%), and prior surgery (30% vs 22%; p < 0.001). Conclusions: We propose that ≥24-hour delay from ED triage to appendectomy is not associated with increased rate of severity upgrade from simple to complicated appendicitis. When upgrade occurs, it is correlated with older age, higher CCI, smoking history, and prior surgery and is associated with worse clinical outcomes.

Abstract
Squamous cell carcinoma (SCC) of the colon is an extremely rare condition, and its pathogenesis is not fully understood. Bowel perforation is a very infrequent manifestation of colonic SCC, and only a few cases have been reported in the literature involving sigmoid and splenic flexure perforation. To the best of our knowledge, no cases of ileocecal perforation have been documented in the literature. Here we present a case of cecal SCC that presented with bowel perforation, necessitating emergent surgical intervention. Histopathological examination showed SCC with lymph node metastasis. This case reviews current knowledge and highlights the rare manifestation that these rare tumors can present.

Abstract
Acute cholecystitis or inflammation of the gallbladder is a common cause of hospitalizations. A percentage of those patients will progress to gangrenous cholecystitis and perforation. This medical emergency can lead to peritonitis, which has increased morbidity and mortality. The first-line modality for the diagnosis of acute cholecystitis is an ultrasound, but if it is inconclusive, then a computed tomography (CT) scan may be beneficial. Gangrenous cholecystitis and perforation have been reported in asymptomatic diabetic patients secondary to diabetic neuropathy and/or gallbladder ischemia leading to nerve denervation. Yet, here we present the case of an asymptomatic non-diabetic patient with gangrenous gallbladder perforation that was treated with antibiotics and drain placements. Diagnosis and treatment involve the collaboration between primary care, interventional, and diagnostic services to appropriately manage these patients. This case demonstrates that clinicians should have a low threshold to conduct CT scan of the abdomen, especially when there is a sudden resolution of pain.

Abstract
Background: Although previous studies have evaluated whether use of irrigation decreases postoperative intraabdominal abscess (PO-IAA) formation, these studies treated irrigation as a dichotomous variable and concluded that no irrigation resulted in a decreased incidence of PO-IAA formation. However, a recent study found decreased incidence with small aliquots to a total volume of 6 L. We hypothesized that higher volumes of irrigation would result in a lower incidence of PO-IAA. Materials and Methods: A postoperative template was developed as a quality improvement initiative and included descriptors for complex appendicitis and volume of irrigation. Data were prospectively collected from February 2016 to December 2018. Patients with complex appendicitis (fibropurulent exudate, extraluminal fecalith, well-formed abscess, visible hole in the appendix) were identified and analyzed by using standard statistical analysis. Volume of irrigation was categorized for analysis. Results: Two thousand three hundred six appendicitis patients were identified; 408 had complex appendicitis (17.7%). Three hundred eighty-four patients with complex appendicitis had documented irrigation volumes. The overall incidence of PO-IAA was 13.8%. Irrigation was commonly used (92.7%). The median amount of irrigation was 1000 mL (500 mL, 2500 mL), but it ranged from none to 9000 mL. There was no overall difference in the volume of irrigation used between those who developed a PO-IAA and those who did not (P = .34). No specific intraoperative finding was associated with the development of PO-IAA. Increasing volume of irrigation did not lower PO-IAA incidence (P = .24). Conclusions: The volume of irrigation did not appear to affect the rate of PO-IAA formation. The use of irrigation should be left to the discretion of the operating surgeon.

Abstract
BACKGROUND Approximately one-third of children with appendicitis present with advanced disease or perforation. Whereas this increases the risk for post-operative complications and re-admission, it is not yet possible to predict early on who will develop an abdominal abscess. We sought to identify specific risk factors for this complication, in an attempt to streamline post-operative care. PATIENTS AND METHODS We reviewed the records of all cases of perforated appendicitis over a 12-month period at a tertiary children's hospital. All patients who developed an abscess despite treatment minimum of seven days of antibiotic therapy were identified. Patients who presented or were re-admitted with an abscess were excluded from analysis. Records were reviewed for demographics, laboratory results, progression of oral intake, and vital signs. RESULTS Of 273 patients with appendicitis, we identified 59 cases of perforated appendicitis. Fifteen patients were excluded. Eight of the remaining 44 patients (18.2%) developed an abscess during their initial admission. Their mean length of stay was longer than that of patients without an abscess (13.4 ± 7.1 vs. 6.9 ± 1.9 d, p < 0.0001). Gender, leukocytosis, or diarrhea at presentation, maximum temperature on post-operative day 3, and maximum heart rate on post-operative day 3 were not statistically different. Diet progression was different between the two groups: none of the 21 patients who were tolerating a regular diet by post-operative day 3 developed an abscess, compared with 8 of the 23 patients who were not yet eating a regular diet on post-operative day 3 (p < 0.01). Late leukocytosis also correlated with the presence of an abscess: 7 of the 8 patients with an abscess had persistent leukocytosis at days 5 through 7, compared with 3 of 31 patients without abscess (p < 0.05). An ultrasound was obtained for these 3 patients and proved normal. CONCLUSIONS Tolerating a regular diet three days after appendectomy for perforated appendicitis decreased the likelihood of a post-operative abscess. No other parameter was predictive of this complication early in the post-operative period. If confirmed in a larger prospective study, this finding may help decrease the length of stay for low-risk patients, and identify abscesses in high-risk patients in a timely fashion.

Abstract
BACKGROUND In the future, surgical management of pediatric appendicitis might become limited to nonperforating appendicitis. Thus, it becomes increasingly important to differentiate advanced from simple appendicitis and to predict perforated appendicitis among a group of children with right-sided abdominal pain, which was the aim of this study. METHODS An institutionally approved, single-center retrospective analysis of all patients with appendectomy from January 2009 to December 2010 was conducted. All diagnostic aspects were evaluated to identify predictors and differentiators of perforated appendicitis. RESULTS In 2 years, 157 children suffered from appendicitis. Perforation occurred in 47 (29.9%) of the patients. C-reactive protein (CRP) levels higher than 20 mg/dL ( P = .037) and free abdominal fluid on ultrasonography ( P = .031) are the most important features to differentiate perforated from simple appendicitis. Moreover, all children with perforation had a positive Heidelberg Appendicitis Score (HAS). A negative HAS excludes perforation in all cases (negative predictive value = 100%). DISCUSSION Perforated appendicitis can be ruled out by the HAS. In a cohort with right-sided abdominal pain, perforation should be considered in children with high CRP levels and free fluids or abscess formation on ultrasound.

Abstract
There are many reports on the endoscopic management of ingested foreign bodies in the upper gastrointestinal tract, however, little is known about the management of a specific subset of esophageal foreign bodies - impacted esophageal foreign bodies (IEFBs), especially perforating esophageal foreign bodies (PEFBs). The aim of this retrospective study on 78 cases was to report experience and outcome in the endoscopic management of the IEFBs in Chinese patients. From January 2006 to July 2011, a total of 750 patients with suspected upper gastrointestinal foreign bodies were admitted to the endoscopy center. Among these 750 patients, 78 cases that met the defined criteria of IEFBs were retrospectively enrolled in the present study, including 12 cases (12/78, 15.4%) with PEFBs. The major types of IEFBs were poultry bones (35.9%) and fish bones (17.9%). Most of the IEFBs (80.8%) were located in the upper esophagus, as were two thirds (66.7%) of the PEFBs. Foreign-body retrieval forceps were the most frequently used accessory devices. Extraction of IEFBs failed in eight patients (10.3%) during the endoscopic procedure. The difficult points in endoscopic management were PEFBs, IEFBs with sharp points, and those with impaction for more than 24 hours. IEFBs should be treated as early as possible, and their endoscopic management is safe and effective. Endoscopic management is the first choice for PEFBs when the duration of impaction is less than 24 hours and there are no abscesses outside of the esophageal tract as determined by a computed tomography scan.

Abstract
The quest to understand how the brain is able to store information for later retrieval has been pursued by many scientists through the years. Although many have made very significant contributions to the field and our current understanding of the process, few have played as pivotal a role in advancing our understanding as William T. Greenough. The current report will utilize associative learning, a training paradigm that has greatly assisted in our understanding of memory consolidation, to demonstrate how findings emerging from the Greenough laboratory helped to not only shape our current understanding of learning induced anatomical plasticity, but to also launch future analyses into the molecular players involved in this process, especially the Fragile X Mental Retardation Protein.
