The aim of the study is to determine and explain the main progressive methods of surgical treatment of obstructive diseases of vessels of different calibers that lead to circulatory disorders and tissue necrosis. The following research methods were used in the work: statistical method, bibliographic, and bibliosemantic. The main indications for lower limb amputation are severe infection, tumor, various types of injuries, gangrene, and limb deformities. In international practice, the most common pathology leading to lower limb amputation is diabetes mellitus and peripheral vascular disease. Critical limb ischemia is the most severe stage of peripheral arterial disease and is characterized by ischemic pain at rest and/or tissue loss. In such patients, the main goal of treatment is to preserve the affected limb. Among some complications that can be successfully treated, only two were noted (which is 9.8% of the total): distal embolization of the peripheral arterial bed and arterial perforation with subsequent bleeding. These conditions significantly worsened the prognosis of the underlying disease. The practical significance of the proposed work can be considered the conclusions that at the first symptoms of lower limb ischemia, one can resort to different types of angioplasty with an improvement in the patient's condition, and in advanced cases it is better to resort to a radical method - amputation, to save the patient's life, in addition, this study brings to science the prospect of creating new methods of limb amputation and new methods of combating ischemia.</p>","PeriodicalId":12610,"journal":{"name":"Georgian medical news","volume":" 356","pages":"28-38"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143038010","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}

Nitrosamines are mutagens, genotoxic substances, and mediators of phototoxicity/carcinogenicity, whose long-term daily usage, in the context of polypharmacy, can result in the parallel appearance of heterogeneous forms of skin cancer: keratinocytic and melanocytic. But a number of clinical observations suggest that it is the nitrosamines that potentiate the multiple occurrences of skin cancer over the years, or recurrences of skin cancer localized in areas exposed to solar radiation. This article reports the occurrences of keratoacanthoma and multiple actinic keratoses in a patient on systemic therapy with telmisartan and tamsulosin - medications that contain Nitrosamines/ NDSRIs. Successful surgical treatment by modificated advancement flap and cryotherapy was performed. The role of nitrosamines as mediators of phototoxicity in the context of drug-mediated Photo-Nitrosogenesis/ Nitrosocarcinogenesis is discussed. Contamination of certain classes of drugs with nitrosamines is proving to be more than a serious problem. This problem is fueled on the one hand by the fact that nitrosamines are 1) photocarcinogens (known for decades), but on the other hand, they are also 2) mutagens/carcinogens, genotoxic substances (according to the FDA classification). The phototoxic effect according to current data is not calculated by the tests provided by the regulators (at least so far), which in practice leads to a miscalculation of the total, cumulative carcinogenic effect in the context of the intake of a contaminated mono or polymedication. The tests could be seen as either largely static, according to some clinical observations-even as categorically insufficient in terms of defining the concept of carcinogenicity in real-world settings (such as the intake of carcinogens with drugs, for example). The processes of carcinogenesis are dynamic, multifactorial and could hardly be characterized by this kind of tests. New literature evidence finds a disconnect precisely in the determination of carcinogenic activity by assays proposed by regulators such as the Ames test (in bacteria) and the CPCA test in rodents. An open dilemma remains: since there is no concordance between the mutagenicity test in bacteria (Ames) with that in rodents (CPCA), what should be their significance in humans? For this reason, the application of the above-mentioned tests might be seriously limited in the future. We present a patient with multiple actinic keratoses and an epithelial skin tumor in the scalp area that developed during therapy with Tamsulosin and Telmisartan. We comment on the role of drug-mediated Photo-Nitrosocarcinogenesis/Oncopharmacogenesis in the background of potential/actual carcinogen contamination.</p>","PeriodicalId":12610,"journal":{"name":"Georgian medical news","volume":" 356","pages":"89-93"},"PeriodicalIF":0.0,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143038038","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}
