Currently, the “gold” standard of treatment for patients with non‑metastatic cancer of the stomach and esophageal–gastric junction is surgical treatment, which is complemented by perioperative chemotherapy according to the FLOT scheme, which includes four courses of therapy before surgery and four after. However, according to statistics, less than half of patients complete all adjuvant courses of FLOT chemotherapy due to the high toxicity of the regimen and a decrease in the functional status of patients in the postoperative period.

Identification of structural and functional changes in pelvic lymph nodes in experimental metastatic prostate cancer.Materials and methods. The study included 30 male mice aged 3 months. All animals (n = 30) were divided into 2 groups. The first group (the main one, n = 20) included mice that had a model of metastatic prostate cancer created by transplanting an Ehrlich tumor into the prostate parenchyma. These animals were further divided into two equal subgroups: 1a (n = 10) – mice were withdrawn from the experiment on day 7; 1b (n = 10) – mice were withdrawn from the experiment on day 18. The second group (n = 10) included mice that were not manipulated, they made up the control group. After the end of the experiment, morphological analysis of the prostate gland and regional (pelvic) lymph nodes in mice of both groups was performed using light microscopy. Statistical processing of the results was carried out using the Statistica 8.0 software package. The differences were considered statistically significant at p < 0.05.Results. When compared to the control group the mice of groups 1a and 1b, the prostate parenchyma was almost completely replaced by atypical cells, which demonstrates the presence of neoplastic processes in the prostate gland. In group 1a mice, the number of pelvic lymph nodes was 1.9 times as large, and in group 1b animals, this indicator was 2.7 times higher compared to the second group (p < 0.01). In animals of the first group, the proportion of mast cells in the pelvic lymph nodes increased by 121 % compared to the control group (p < 0.01). At the same time, we revealed a direct relationship of mast cells with the number of tumor cells and immunoblasts in the medullar sinuses, which indicates the participation of tissue basophils in tumor metastasis. We also recorded a significant increase in the area of the medullar sinuses of regional lymph nodes in animals of groups 1a by 12.4 % (p < 0.05) and 1b by 20.2 % (p < 0.01) against the background of an increase in the number of mast cells in this zone compared to the control group, which indicates the possible participation of mast cells in lymphangiogenesis.Conclusion. Mast cells can potentially play a role in the development of malignant neoplasms of the prostate gland. The number of mast cells increases in pelvic lymph nodes in animals with a created model of metastatic prostate cancer. The obtained direct dependence of the increase in the number of mast cells and the increase in the number of tumor cells with immunoblasts suggests the participation of tissue basophils in the spread of metastases. It can be assumed that infiltration of lymph nodes by mast cells may correlate with a poor prognosis of prostate cancer, since these granulocytes contribute to tumor metastasis.","PeriodicalId":334809,"journal":{"name":"Research and Practical Medicine Journal","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114398871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To conduct a retrospective analysis of the results of providing urological care to patients with chronic balanoposthitis on the background of carbohydrate metabolism disorders..Patients and methods. A retrospective analysis of the results of treatment of phimosis due to chronic balanoposthitis in 95 patients was carried out. All patients were divided into two groups. The 1st group included men who showed signs of impaired carbohydrate metabolism (n = 41; 43.1 %). The 2nd group consisted of patients who had no metabolic disorders (n = 54; 56.9 %). The average age of 41 men of the first group was 48.2 ± 17.5 years, the second group of 54 men – 44.6 ± 15.3 years (p > 0.05). According to the indications, all patients underwent local therapy with antiseptics and antimicrobial drugs. In the presence of frequent relapses of balanoposthitis, persistent pain syndrome, the presence of phimosis according to the indications, circumcision of the foreskin was performed. In all patients, the time of surgery, the volume of blood loss during circumcision, and the duration of wound healing were evaluated. We considered the clinical case completed after complete regeneration of the wound.Results. Conservative therapy of balanoposthitis in patients without impaired carbohydrate metabolism was effective in 85.1 %, and in men with type 2 diabetes mellitus (DM2) only in 9.7 %. Consequently, hyperglycemia reduces the effectiveness of conservative therapy of this disease by eight times. In patients with DM2, circumcision was performed 4.6 times more often than in the control group. The correlation of signs of hyperglycemia and the need for surgical treatment of balanoposthitis was 0.66. The duration of circumcision in group 1 was longer by 7.3 ± 3.6 min. compared with the second group (p < 0.05). Wound healing in patients with DM2 was observed almost twice as long (p < 0.05). Thus, with DM2, balanoposthitis is more difficult to treat. If balanoposthitis has a recurrent course, then circumcision can be considered as the final treatment option.Conclusion. Balanoposthitis in patients with impaired carbohydrate metabolism often has a chronic form. In patients with DM2, conservative therapy of inflammation of the foreskin of the penis is effective in one out of ten cases. In adult men, balanoposthitis was more common in middle and old age. Among patients of this age, 11 (26.8 %) people had hyperglycemia for the first time. Consequently, men of the above age may be at risk and need more careful examination of the external genitalia and control of the level of glycemia.","PeriodicalId":334809,"journal":{"name":"Research and Practical Medicine Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132741761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessment of safety and short‑term effectiveness of high and very high‑risk prostate cancer neoadjuvant chemo‑ hormonal treatment without distant metastases.Patients and methods. Combined hormone chemo‑ radiation treatment of 33 patients with prostate cancer of high and very high risk of progression without distant metastases was performed. Metastases to regional lymph nodes were found in 9 patients according to the examination data (MRI, MSCT), no metastases were detected in 24 patients. All patients underwent combined chemohormonal therapy in the amount of 4 courses of docetaxel intravenously at a dose of 75 mg/m2 every 3 weeks as the first stage of treatment. in combination with androgen deprivation therapy with agonists or antagonists of GnRH before performing radical radiation therapy (combined or remote). All patients underwent neoadjuvant hormone therapy: 16 patients – with the use of GnRH antagonists (Degarelix), 17 – with the use of GnRH agonists (Gozerelin/Leuprorelin/Triptorelin). The toxicity of the presented treatment regimen and its immediate effectiveness – the effect on the level of prostate‑s pecific antigen (PSA), prostate volume, and the quality of urination – were evaluated.Results. Treatment regimen was highly effective concerning PSA decrease (from initial median level 79,67 ng/ml to 1,45 ng/ml after neoadjuvant treatment), all subjects responded well, no non‑responders observed. Median prostate volume decreased from 44 cm3 to 25 cm3 after treatment, which guaranteed availability and safety of further radical radiation treatment. Urinary function was restored in all subject with initial urinary retention.Conclusion. Neoadjuvant chemo‑h ormonal treatment was highly effective in PSA level, prostate volume decrease and functional results improvement which secured further radical radiation treatment in one of its types.

Acute renal injury in patients with kidney cancer after surgical treatment may be accompanied by the development of early (hyperhydration, electrolyte balance disorders, hyperkalemia, acid‑base condition disorders, uremic intoxication) and late chronic kidney disease complications. The incidence of these complications increases with an increase in the volume of kidney resection, as a result of which it is important to take into account risk factors, timely diagnosis of the degree of kidney damage and medical measures aimed at restoring kidney function. Currently, the possibility of using various molecules as early markers of kidney damage, which help not only assess the presence of kidney damage, but also localize it, is being studied. For example, albumin, serum cystatin C, alpha 1‑microglobulin, P2‑microglobulin – markers of glomerular damage, NGAL, KIM‑1; L‑FABP, urine cystatin‑C, IL‑18 – reflect damage to the proximal tubule, GST, NGAL – distal tubule, calibindin D28 ‑ characterizes damage to the collecting duct, osteopontin, NHE‑3 – are associated with damage to the loop of Henle. Measures of a curative and preventive nature (infusion therapy, anti‑ischemic protection, modulation of ferroptosis, renal replacement therapy), as well as dynamic monitoring of the main biomarkers of renal damage are aimed at preventing the persistence of the pathological process with a possible outcome into chronic kidney disease, which is especially undesirable in patients with single kidney cancer. The main directions of medical and preventive measures in patients with acute kidney injury should be considered: 1) the fastest possible elimination or minimization of the effect of tumor tissue; 2) control and correction of life‑threatening complications of renal dysfunction (hyperhydration, electrolyte balance disorders (hyperkalemia), acid‑base state, uremic intoxication). Methods of anti‑ischemic protection include a number of surgical techniques aimed at 1) minimizing ischemia time, 2) reducing the intensity of volatile metabolic processes in the kidney, 3) training renal parenchyma for hypoxic conditions (receiving ischemic preconditioning).Duration of renal ischemia represents an important modifiable factor affecting early and distant renal function in surgically exposed patients.

To evaluate the intensity of healing of an infected skin wound in rats using Trigonella foenum- graecum (Fenugreek) against the background of experimental steroid hyperglycemia.Materials and methods. The rats included in the study (n = 20) were divided into two equal groups. First, a model of steroid hyperglycemia was created for all animals. Then the same animals (n = 20) were used to create models of infected skin wound. The rats of the first group (the main one) were treated with wound surface ointment containing Trigonella foenum- graecum. Also, Trigonella foenum- graecum extract was constantly added to the water for the rats of the first group. Intact vaseline ointment was applied to the wound of the second group (control) rats.

This study showed several positive aspects of the use of Trigonella foenum-g raecum in terms of treatment of infected skin wounds in animals with steroid hyperglycemia. The decrease in glucose levels almost to baseline values in the rats of the main group against the background of oral administration of Trigonella foenum-g raecum was recorded. By the end of the observation, the level of glycemia was almost two times less in animals of the first group compared to the second (p < 0.05).

To analyze levels of sex hormones and cortisol in lung tissues of patients with lung cancer with previous COVID‑19 of different severity.Materials and methods. The material for the study included samples of lung tissues obtained after open biopsy at radical surgery from 60 patients with morphologically verified stage I–IIIA non‑small cell lung cancer (NSCLC) (сT1–3NХ M0). The mean age of patients was 59.11 ± 2.9 years. All patients had negative results of SARS‑CoV‑2 nasopharyngeal swab PCR testing at hospitalization. Based on the anamnestic data collected using a special questionnaire, the main and control groups were formed depending on COVID‑19 severity. The main group included 30 NSCLC patients (15 men and 15 women) after severe or moderate COVID‑19 who had required hospitalization; the control group included 30 patients with NSCLC after asymptomatic or mild SARS‑CoV‑2 infection. All patients underwent COVID‑19 infection for 3 months or more before the start of NSCLC treatment. Quantitative assessment of estradiol (E2), testosterone (T), progesterone (P4) and cortisol (C) was performed by RIA in 10 % homogenates of the tumor and resection line tissues.Results. Resection line tissues in women of the main group showed an increase of E2 by 1.7 times, C by 1.6 times, P4 by 4.1 times, and a decrease of T by 1.3 times; in men, levels of T and P4 were increased on average by 1.8 times (p < 0.05).

Significant prognostic factors, e.g. the invasive component of Paget’s cancer, the involvement status of regional lymph nodes, morphological criteria, the grade of malignancy, overexpression of epidermal growth factor Her2/neu, the presence of BRCA 1/2 and CHEK2 gene mutations, as well as age, affect the prognosis of Paget’s disease. According to various sources, PBC in 90–98 % is combined with invasive or non‑invasive breast cancer. For the most part, the lesion is multifocal. There’s high expectation for PBC to form tumor node. A palpable tumor node in the mammary gland is detected in half of the patients. PBC has certain features and specificity in relation to treatment methods. The method of radical surgical treatment of patients is primarily based on performing oncoplastic resections. Sufficient breast volume is a significant criterion for the possibility of performing an organ‑ preserving operation. The organ‑ preserving treatment is oncologically safe in case of PBC. The removal of the nipple‑ areolar complex is mandatory in case of PBC.

The number of cases of newly diagnosed hepatocellular cancer (HCC) in the Russian Federation in 2019 accounted to 9324. Currently, the method of transarterial chemoembolization (TACE) is widely used for the treatment of patients with malignant liver tumors. Various methods of transarterial embolization of the liver are used, including selective or superselective catheterization and the use of various chemotherapeutic and embolizing agents. In recent years, calibrated synthetic microspheres loaded with a chemotherapeutic agent have been developed. They ensure uniform and prolonged release of the drug and the achievement of high concentrations of the chemotherapeutic agent in tumor cells. The method of transarterial embolization of the liver using grains containing the drug is known as DEB‑TACE (Drug‑eluting bead transarterial chemoembolization).  The traditional TACE (conventional transarterial chemoembolization), technique is also widely used, in which a chemotherapeutic drug is administered together with lipiodol, and then with occlusive material. When comparing the techniques, no differences were found in their safety profiles. Despite the fact that transarterial embolization of the liver is considered a safe procedure, it is not without the risk of complications, the most common of which are acute cholecystitis and leukopenia. Also, a frequent undesirable phenomenon after transarterial chemoembolization of the liver is postembolization syndrome, which includes abdominal pain, hyperthermia up to 38 °  C and nausea. One of the rare complications occurring in less than 1% of cases is a complication of liver TACE – the development of a liver abscess against the background of tumor necrosis. It is believed that the formation of an abscess can lead to the formation of fistulas: hepaticobronchial, hepaticoduodenal, hepaticogastric, etc. Our article presents a rare clinical case of hepatogastric fistula formation after liver TACE.","PeriodicalId":334809,"journal":{"name":"Research and Practical Medicine Journal","volume":"63 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120862501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
