The Relationship between Tumor Budding and Tumor Deposits in Patients with Stage III Colorectal Carcinoma.

Recently, some new morphological features of colorectal cancer have been discovered as important prognostic factors; in this paper, we study the relationship between tumor budding (TB) and tumor deposits (TDs). The retrospective cohort study included 90 patients with pathohistologically confirmed stage III CRC who were treated with radical surgical resection. All hematoxylin and eosin (H and E)-stained slides from each patient were reviewed, and histological parameters were recorded.

COMPARISON OF C-REACTIVE PROTEIN LEVELS IN SERUM AND PERITONEAL FLUID IN EARLY DIAGNOSIS OF ANASTOMOTIC LEAKAGE AFTER COLORECTAL SURGERY.

In colorectal surgery, anastomotic leakage is a serious complication, leading to higher postoperative morbidity and mortality. The aim of this study was to evaluate the accuracy of serum and intraperitoneal C-reactive protein (CRP) in early diagnostics of anastomotic leakage on the first four postoperative days after colorectal surgery. From January to October 2019, fifty-nine patients with colorectal carcinoma were operated on, with formation of primary anastomosis.

Association of Gut and Chronic Spontaneous Urticaria.

(1) Background: Chronic spontaneous urticaria (CSU) has been linked to the dysbiosis of the gut microbiota. Furthermore, various studies have highlighted the anti-inflammatory properties of short-chain fatty acids (SCFAs), whose production is primarily regulated by the gut microbiota. However, only a few studies have investigated the role of major SCFA producers, such as , in skin inflammatory diseases.

Expression and Prognostic Significance of PD-L1 and NY-ESO1 in Gallbladder Carcinoma.

Background/aim: Gallbladder cancer is a rare malignancy with a very high mortality, usually due to diagnosis in an advanced stage of the disease. Therefore, the aim of this study was to evaluate the clinical significance of cancer/testis antigen 1A (CTAG1A, NY-ESO1) and CD274 molecule (PD-L1, the ligand for programmed cell death protein 1) and their impact on the overall survival of patients with gallbladder cancer.

Patients And Methods: Using immunohistochemical staining, we determined the expression of NY-ESO1 in tumor cells (positivity: cytoplasmic/nuclear staining of any intensity in ≥50%) and PD-L1 in tumor cells and intratumoral immune cells (positivity: cytoplasmic/membranous staining of any intensity in ≥1%).

Background: This research looks at the connection between psychological stress and the prevalence of hand eczema (HE) among physicians and dentists (surgeons, non-surgeons).

Methods: This cross-sectional field study involved 185 participants: physicians (surgeons, non-surgeons), dentists (surgeons, non-surgeons) and controls. Hand lesions were examined using the Osnabrueck Hand Eczema Severity Index (OHSI), and participants answered the Nordic Occupational Skin Questionnaire (NOSQ) and Perceived Stress Scale (PSS).

Multiple Primary Angiosarcomas of the Colon.

Introduction: Gastrointestinal angiosarcomas are rare and represent less than 1% of all gastrointestinal tract malignancies, with most occurring in the stomach and small intestine. Occurrence in the colorectal segments is considered extremely rare. .

Comparison of hypofractionation and standard fractionation for post-prostatectomy salvage radiotherapy in patients with persistent PSA: single institution experience.

Background: Hypofractionated post-prostatectomy radiotherapy is emerging practice, however with no randomized evidence so far to support it's use. Additionally, patients with persistent PSA after prostatectomy may have aggressive disease and respond less well on standard salvage treatment. Herein we report outcomes for conventionally fractionated (CFR) and hypofractionated radiotherapy (HFR) in patients with persistent postprostatectomy PSA who received salvage radiotherapy to prostate bed.

Urinary troponin concentration as a marker of cardiac damage in pregnancies complicated with preeclampsia.

Pregnant women with preeclampsia experience significant hemodynamic changes which lead to an increased myocardial workload. In response to increased demands in pregnancy, the heart muscle responds with ventricular remodeling process which involves cardiac muscle hypertrophy. Opposed to occurrence of eccentric ventricular hypertrophy in normal pregnancy, myocardial remodeling in a form of concentric hypertrophy will occur in pregnant patients with preeclampsia.

Retrorenal fat predicts grade C pancreatic fistula after pancreaticoduodenectomy.

Background: Pancreatic fistula after pancreaticoduodenectomy is one of the most severe complications with mortality rates as high as 45%, and the prediction of most severe form of fistula (grade C) is crucial for successful management of patients who are to undergo cephalic pancreatoduodenectomy. It has been found that the amount of abdominal fat may predict grade C postoperative pancreatic fistula. In this study, we analysed the value of retrorenal fat thickness in the prediction of grade C pancreatic fistula.

TREATMENT OF HUMERAL SHAFT FRACTURES: ANTEGRADE INTERLOCKING INTRAMEDULLARY NAILING WITH ADDITIONAL INTERLOCKING NEUTRALIZATION SCREWS THROUGH FRACTURE SITE.

Validation of a clinical score in predicting pancreatic fistula after pancreaticoduodenectomy.

Background: Postoperative pancreatic fistula (POPF) is one of the most severe complications after cephalic pancreaticoduodenectomy, with mortality as high as 30%. Risk scores may help predict the risk of POPF. Multiple external validations substantially improve generalized clinical acceptability of a scoring system.

DISCHARGE AFTER ELECTIVE UNCOMPLICATED LAPAROSCOPIC CHOLECYSTECTOMY: CAN THE POSTOPERATIVE STAY BE REDUCED?

- The aim of the study was to reevaluate the safety and feasibility of discharge 24 h after elective uncomplicated laparoscopic cholecystectomy. Since the introduction of laparoscopic cholecystectomy in our hospital, the minimum postoperative stay was considered to be two days based on surgeons' experience. The study included 337 operations performed by 21 surgeons during 2016 in the Sestre milosrdnice University Hospital Centre.

Bypassing major venous occlusion and duodenal lesions in rats, and therapy with the stable gastric pentadecapeptide BPC 157, L-NAME and L-arginine.

Aim: To investigate whether duodenal lesions induced by major venous occlusions can be attenuated by BPC 157 regardless nitric oxide (NO) system involvement.

Methods: Male Wistar rats underwent superior anterior pancreaticoduodenal vein (SAPDV)-ligation and were treated with a bath at the ligated SAPDV site (BPC 157 10 μg, 10 ng/kg per 1 mL bath/rat; L-NAME 5 mg/kg per 1 mL bath/rat; L-arginine 100 mg/kg per 1 mL bath/rat, alone and/or together; or BPC 157 10 μg/kg instilled into the rat stomach, at 1 min ligation-time). We recorded the vessel presentation (filled/appearance or emptied/disappearance) between the 5 arcade vessels arising from the SAPDV on the ventral duodenum side, the inferior anterior pancreaticoduodenal vein (IAPDV) and superior mesenteric vein (SMV) as bypassing vascular pathway to document the duodenal lesions presentation; increased NO- and oxidative stress [malondialdehyde (MDA)]-levels in duodenum.

The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding (PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up.

Sensitivity and Specificity of Fenyö-Lindberg and Teicher Scores in the Diagnosis of Acute Appendicitis in Women.

The aim of the study was to assess diagnostic accuracy (sensitivity and specificity) of Fenyö-Lindberg and Teicher scores for distinguishing patients that need immediate surgical treatment from the others, in a female population from an urban setting. The study prospectively included 130 female patients admitted to the emergency department with abdominal pain indicating acute appendicitis. The scores and parameters of validity were calculated and compared to definitive diagnosis.

Pancreatic surgery: evolution and current tailored approach.

Surgical resection of pancreatic cancer offers the only chance for prolonged survival. Pancretic resections are technically challenging, and are accompanied by a substantial risk for postoperative complications, the most significant complication being a pancreatic fistula. Risk factors for development of pancreatic leakage are now well known, and several prophylactic pharmacological measures, as well as technical interventions have been suggested in prevention of pancreatic fistula.

Significance of surgery for prognosis of GIST in cohort from transitional healthcare settings.

Objective: Despite significant improvement in survival of gastrointestinal stromal tumors (GIST) due to use of tyrosine kinase inhibitors, surgery still represents the important part of clinical management. The aim of our study was to retrospectively analyze prognosis of GIST depending on the success of surgical treatments and utilization of chemotherapy in transitional country with relatively limited resources.

Methods: cohort of consecutive patients operated for GIST in tertiary medical center, within time frame 1999-2012.

Familial adenomatous polyposis in three generations of a single family: a case study.

Background: Familial adenomatous polyposis (FAP) is an autosomal dominantly inherited syndrome characterized by the development of numerous polyps in the colon and rectum. If left untreated, the affected patients inevitably develop colon cancer by the age of 40 years. A resection of the colon (colectomy) or of the colon and rectum (proctocolectomy) is needed to minimize the risk of cancer.

Giant mixed-type liposarcoma of the mesentery: case report.

Primary mesenteric liposarcomas are very rare, especially when they are of mixed histologic pattern. Patient prognosis is based upon the most aggressive histologic type of liposarcoma. A case is reported of a 77-year-old man with a history of slowly increasing abdominal volume over 3 years.

Secondary arterio-enteric fistula: case report and review of the literature.

Arterio-enteric fistula is a rare, but potentially deadly cause of gastrointestinal bleeding. The disease occurs in two forms: primary as a result of atherosclerotic aortic aneurysm, aortitis, trauma, radiation, tumor invasion or penetrating ulcer, and secondary as a consequence of surgical aortal reconstruction. The clinical manifestation is mostly gastrointestinal bleeding, rarely back pain, fever and sepsis.

Lack of prognostic significance of connexin-43 labeling in a series of 46 gastrointestinal stromal tumors.

Background: Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors with variable malignant potential. Connexin-43 (Cx43) is the commonest gap-junction protein and has been frequently investigated in oncology. Our aim was to establish the immunohistochemical expression of Cx43 in relation to GIST location, size, Ki67 index, tumor grade and follow-up.

The vascular hybrid room--operating room of the future.

The last two decades have seen a paradigm shift in the treatment of vascular related diseases from once traditional open surgical repairs to the entire vascular tree being amenable to percutaneous interventions. Neither the classic operating room nor the conventional angiography suite is optimal for both open surgery and endovascular procedures. Important issues for the vascular hybrid operating room include quality of the imaging equipment, radiation burden, ease of use of the equipment, need for specially trained personnel, ergonomics, ability to perform both open and percutaneous procedures, sterile environments, as well as quality and efficiency of patient care.
