[Domestic system for fluorescent diagnostics in breast cancer: pros and cons]. / Otechestvennaya sistema dlya flyuorestsentnoi diagnostiki pri rake molochnoi zhelezy: za i protiv.

OBJECTIVE: To analyze the effectiveness of identifying the sentinel lymph node in breast cancer using the «MARS¼ system for fluorescent diagnostics in near infrared light. MATERIAL AND METHODS: There were 51 patients with breast cancer cT0-2N0M0 between July 2023 and October 2023. Mean age of patients was 52.3 years. Invasive ductal carcinoma was diagnosed in 39 (76.5%) patients, invasive lobular carcinoma - in 8 (15.7%) patients, other forms of breast cancer - in 4 (7.8%) patients. RESULTS: Sentinel lymph node was successfully identified in all cases (n=51). A total of 122 sentinel lymph nodes were detected and mapped (2.4 nodes per a patient). CONCLUSION: The MARS system for intraoperative fluorescence diagnostics in near-infrared light is effective for identifying the sentinel lymph node in breast cancer.

[Pneumatosis cystoides intestinalis: a case report and literature review]. / Kistoznyi pnevmatoz tonkoi kishki: klinicheskii sluchai i obzor literatury.

Pneumatosis cystoides was first described by Du Vernay in 1783. This is a fairly rare disease with nonspecific symptoms and CT data on pneumoperitoneum. The authors present pneumatosis intestinalis in a patient with systemic connective tissue disorder. Free gas in abdominal cavity and dilated intestinal loops were an indication for emergency surgery with subsequent resection of intestine due to signs of ischemic damage. A review of clinical cases allows us to conclude that pneumoperitoneum requires careful differential diagnosis. Free gas in abdominal cavity in patients with cystic pneumatosis is an indication for emergency surgery only in case of complicated course of disease.

[Rare causes of acute purulent-inflammatory lesions of pararectal tissue and Fournier's gangrene]. / Redkie prichiny ostrogo gnoino-vospalitel'nogo porazheniia pararektal'noi kletchatki i gangreny Furn'e.

National and foreign literature devoted to acute non-cryptogenic suppurations of pararectal tissue was analyzed. Own clinical observations are given. The unsolved questions of terminology and treatment strategy for this rare disease are discussed.

[EFFECT OF ANTIOXIDANTS ON ESOPHAGUS TISSUE REPAIR UPON EXPERIMENTAL CHEMICAL BURN FROM ACETIC ACID].

This work is an experimental study on 30 rabbits to determine the effect of antioxidants on the process of repair of the esophagus. Chemical agent was 46% acetic acid, a The antioxidant "Mexidol" were injected to core group of test animals in 2 weeks. Animals were taken from the experiment at 5, 14, 21, 30, 45 and 60 hours. We conducted morphometric study of histological exemplars, determining the number of inflammatory cells, epithelial thickness, the area of newformed blood vessels. In the study group we reported an improvement of reparative processes in the wall of the body: it was increased blood supply to the burn surface on 242% and more rapid relief of inflammatory processes on 117% (p < 0.05).
