Pictorial depth cues elicit the perception of tridimensionality in dogs.

The perception of tridimensionality is elicited by binocular disparity, motion parallax, and monocular or pictorial cues. The perception of tridimensionality arising from pictorial cues has been investigated in several non-human animal species. Although dogs can use and discriminate bidimensional images, to date there is no evidence of dogs' ability to perceive tridimensionality in pictures and/or through pictorial cues.

Schwannoma of the phrenic nerve. A case report.

Background: Neurogenic tumors are the third most common tumors occurring within the mediastinum. Predominantly completely asymptomatic, they are most often found in the posterior mediastinum, although they may also be located, albeit rarely, in the middle mediastinum. Thus, in the cases of tumors localized in the middle mediastinum, schwannomas of the phrenic nerve must always be considered.

Analysis of Bacterial Pathogens Causing Complicating HAP in Patients with Secondary Peritonitis.

Background: Diffuse peritonitis is an acute abdominal condition characterized by high mortality. The main treatment modality is surgery, requiring a subsequent prolonged hospital stay. These patients are, among other things, at risk of developing hospital-acquired pneumonia (HAP), which considerably worsens their treatment outcomes.

The purpose of the study was an evaluation of the effect of reinforcement suture in the healing of stapler rectal anastomosis and risk factors for anastomotic leakage in mid, upper rectal and sigmoid tumors.

Methods: A total of 357 patients who underwent curative resection for rectal or sigmoid tumor over 5 years were analyzed.

Midgut volvulus in adult age associated with congenital malrotation - case report.

Introduction: Malrotation is understood as a congenital anomaly of the intestinal position formed during embryonic development. Disorders of intestinal rotation and its manifestations in adulthood are less common; the symptoms of these disorders are characteristic of childhood. An asymptomatic bowel rotation disorder occurs in up to 1 of 200 newborns and symptomatic malrotation occurs in 1 of 6,000 live newborns.

Cyclomodulins and Hemolysis in as Potential Low-Cost Non-Invasive Biomarkers for Colorectal Cancer Screening.

The frequent occurrence of positive for cyclomodulins such as colibactin (CLB), the cytotoxic necrotizing factor (CNF), and the cytolethal distending factor (CDT) in colorectal cancer (CRC) patients published so far provides the opportunity to use them as CRC screening markers. We examined the practicability and performance of a low-cost detection approach that relied on culture followed by simplified DNA extraction and PCR in isolates recovered from 130 CRC patients and 111 controls. Our results showed a statistically significant association between CRC and the presence of colibactin genes and , the gene, and newly, the hemolytic phenotype of isolates.

The role of CRP in the diagnosis of postoperative complications in rectal surgery.

Postoperative complications of rectal resections classified as grade III or higher according to Clavien-Dindo system, which also include anastomotic leaks, are usually life-threatening conditions. Delayed diagnosis may account for almost 18% of deaths. Due to nonspecific clinical signs in the early postoperative period, diagnosing these complications may truly be a challenge for clinicians.

[Evolution of Opinions on Chest Wall Stabilisation and Our Experience].

PURPOSE OF THE STUDY Rib fractures represent one of the most common fractures sustained by 10-40% of all patients with blunt chest trauma, their incidence increases with age. In the current literature, however, new indication criteria continue to emerge. The purpose of this study is to assess the indication criteria, the timing of surgery and the use of individual plates in dependence on fracture location in our patients after the chest wall stabilisation in a retrospective analysis.

Candida albicans culture from a rectal swab can be associated with newly diagnosed colorectal cancer.

Plenty of metagenomic studies have suggested possible associations between microbiome composition and colorectal cancer (CRC). However, these techniques are not economic enough for routine use so far. Therefore, we explored the possibility to detect species associated with colorectal cancer by conventional culture from rectal swab.

Current possibilities of minimally invasive therapy of oesophageal diverticula.

Oesophageal diverticula represent a relatively rare pathology of the oesophagus requiring a specific diagnostic and therapeutic approach. Interventional therapy is indicated for symptomatic diverticula, diverticula with other pathologies (tumour in the diverticulum, gastroesophageal reflux disease, low-malignancy gastroesophageal junction tumours). The open surgical approach is being increasingly replaced by minimally invasive surgical, endoscopic and combined methods.

Fistuloclysis as a method of nutritional management in a patient with high output enteroatmospheric fistula - a case report.

Enteric fistula is a pathological communication between the small intestine and surrounding tissue. In case of communication with body surface it is called an enterocutaneous or enteroatmospheric fistula. There are many causes of enterocutaneous/enteroatmospheric fistula occurrence.

Current status of cytoreductive surgery (CRS) and intraperitoneal hyperthermic chemotherapy (HIPEC) in the multimodal treatment of peritoneal surface malignancies.

The tumors of the peritoneal surface, both primary and secondary, are associated with a very poor prognosis and rapid progression through conventional oncology treatment including systemic chemotherapy, targeted treatment, radiotherapy, surgery, and symptomatic treatment. Until recently, most of them were considered incurable. In the 1980s, the first cytoreductive surgery ("CRS") combined with intraperitoneal hyperthermic chemotherapy ("HIPEC") became the standard of treatment for selected tumor peritoneal tumor (pseudomyxoma peritonei and primary peritoneal malignant mesothelioma).
