ABSTRACT

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumor originating from the gastrointestinal tract and have a broad spectrum of clinicopathological features affecting disease management regarding the treatment modalities. Methods: A retrospective study of 49 patients who underwent surgery for gastrointestinal tumors between 2008 and 2016 was conducted. Clinical, pathological, and immunohistochemical features of patients with and without recurrence were statistically analyzed. Results: Twenty-nine (59.1%) patients had gastric; 16 (32.6%) had small intestinal; 3 (6.1%) had mesenteric; and 1 (2.2%) had rectal GISTs. Microscopic tumor necrosis and tumor ulceration were also significant for disease recurrence (P = 0.005, P = 0.049). High-risk patients according to Miettinen's risk classification were more likely to develop a recurrence (P < 0.001). Additionally, high-grade tumors were also a risk factor for recurrence (P < 0.001). Ki-67 levels were available in 40 patients and the mean Ki-67 level was 16.8 in patients with recurrence, which was a significant risk factor in regression analysis (HR: 1.24, 95%, CI: 1.08-1-43). Five-year disease-free survival rates of non-gastric and gastric GISTs were 62.3% and 90%, respectively (P = 0.044). Conclusion: Larger tumors and higher mitotic rates are more likely to develop recurrence. High Ki-67 levels were also associated with recurrence.

ABSTRACT

BACKGROUND: Violence against physicians is a global issue that causes impaired physical and mental health, declined work quality, resignations, and even suicides. Studies regarding violence against physicians are very limited. Therefore, our aim is to investigate the physical violence incidents against physicians presented in print media between 2008 and 2018. METHODS: A total of 8612 news reports acquired in national news database via 45 keywords were assessed. Five hundred and sixty-four of the reports met the inclusion criteria and were retrospectively analyzed. RESULTS: Of 5964 news reports, 3754 (62.9%) were reprimands and protests against violence incidents. In 11 years, 560 individual incidents occurred where 647 physicians were physically assaulted, with 2267 news reports written on those incidents. The number of incidents increased over the years, and in 2012 both the number of incidents (n=91) and news reports count per incident were found highest. About 77.7% of assaulted physicians were male, and incident rate was higher in Western Turkey (42.15%). In 11 years, ten dedicated physicians have lost their lives in the line of duty. Emergency medicine (20.4%), primary care (9.89%) were the departments most exposed to physical violence. The claim of receiving inadequate medical attention was noted to be the primary allegation of the assailants. CONCLUSION: The frequency of physical violence incidents against physicians is increasing. Throughout the study period, news reports containing condemnations, critiques, and protests are also more frequently, yet not adequately, placed in print media. Thus, social and public awareness ought to be enhanced through national and global media outlets. Furthermore, extensive measures must be taken by governments in order to prevent and eliminate violence.

ABSTRACT

BACKGROUND: Acute left colonic diverticulitis (ALCD) ranges from localized diverticulitis to perforation and fecal peritonitis, and treatment varies from conservative management to emergency surgery. The risk factors for recurrence following nonoperative management of ALCD is still controversial. We aimed to define the factors predicting severity level, progression and recurrence risk of ALCD to timely select patients requiring surgery. METHODS: This is a multicenter study where patients were included on accrual. Patients in our clinic between December 2017 and June 2019 with ALCD above 18 years of age were included (n=144) in this study, while 18 years and younger, pregnant or nursing mothers, those with Crohn's disease, ulcerative colitis, colorectal and/or anal cancer were excluded from this study. Laboratory parameters, Modified Hinchey Scores, clinical features, demographics, diet, smoking, alcohol consumption, body mass index, previous diverticulitis episodes, chronic diseases of patients with ALCD, as well as recurrences within 18 months after discharge were evaluated. RESULTS: The findings showed that smoking was more common in patients with previous episodes (p=0.04) and patients who underwent emergency surgery (p=0.04). Recurrence was higher in Modified Hinchey 1b and 2 (p=0.03) than 0 and 1a. Patients who were older than 50y had a higher propensity to undergo emergency surgery than the patients younger than 50y (p=0.049). Nausea, fever, respiratory rate, procalcitonin, total bilirubin and direct bilirubin levels were higher in patients with Modified Hinchey 4 (p=0.03, 0.049, 0.02, 0.001, 0.002, 0.001, respectively). Recurrence was higher in patients with a smoking history, previous ALCD episodes, lower body mass index and pandiverticulitis. CONCLUSION: Laboratory parameters, body mass index, age, clinical features, previous episodes of diverticulitis and smoking may predict the severity and progression of ALCD. Smoking and having low BMI seem to be precursors of ALCD recurrence, especially when the patient with MHS 1b or 2 had at least one previous episode of ALCD. Control colonoscopy results are predictive of recurrence.

ABSTRACT

PURPOSE: The aim of this study is to evaluate the outcomes of pharmacological thromboprophylaxis given for short-term duration to the patients who underwent major abdominal surgery for colorectal and gastric cancer. MATERIALS AND METHODS: This retrospective cohort study was performed in consecutive patients who underwent major abdominal surgery for colorectal and gastric cancer and received short-term pharmacological thromboprophylaxis during hospital stay were enrolled. Complete duplex ultrasonography of the lower limbs was performed for all patients to investigate both symptomatic and asymptomatic deep vein thrombosis (DVT). RESULTS: Overall, 278 patients were evaluated for inclusion and 62 colorectal and 27 gastric cancer patients were enrolled. Of 89 patients, the incidence of total and symptomatic DVT was 4.5% and 2.2%, respectively. The patients with symptomatic DVT were diagnosed within the first four months. The incidence of coronary artery disease, mucinous adenocarcinoma and vascular tumor invasion were significantly higher in patients with DVT (P-values<0.001, 0.009, and 0.02, respectively). CONCLUSION: Short-term pharmacological thromboprophylaxis after major abdominal surgery for colorectal and gastric cancer does not increase symptomatic DVT rates of patients with low Caprini score. Postoperative DVT surveillance may benefit patients with coronary artery disease, mucinous adenocarcinoma or vascular invasion of the tumor.
