EXPERIENCE OF SUCCESSFUL ACNEFORM ERUPTIONS TREATMENT IN PATIENT WITH MULTIPLE MELANOMA

Objective: to describe the results of the joint monitoring and diversified treatment of oncologists and dermatologists those patient with multiple recurrent melanoma who received over a long period a targeted anti-cancer therapy, which was complicated by side-effect as widespread acneform rush, resistant to traditional treatment. Patient A., born in 1988, was followed up and got a treatment more than 2 years in oncology out-patient clinic diagnosed with “Melanoma of the front surface of the left leg T2bN0M0 IIA”. Subsequently, the patient was verified metastasis in the inginal lymph nodes, in the soft tissues of the hips, to liver. Acute adverse reaction has developed in a short time after getting the anti-tumor target therapy as generalized acneform rush and itching of the skin. Skin symptoms accompanied by pronounced psychological and emotional stress, therefore, dermatologists have been invited to provide additional medical assistance to this patient. Due to the fact that subsequent traditional anti-acne algorithms of topical and oral treatment was not such effective, there was made a decision to use an alternative supporting external therapy, which did not have similar examples of usage previously. Results. External application of tacrolimus ointment in combination with other drugs and then as a mono-therapy, allows us in a rather short period achieve a stable and pronounced regression of skin pathological lesions, to return to the previously cancelled initial drug dose of the anti-tumor target therapy, to change significantly components of the patient’s quality of life. Conclusion. The search for additional and alternative treatment approaches for similar patients, as in our case, remains relevant for specialists and patients themselves. This case is an example of alternative approach to the tacrolimus topical application in patient with drug-mediated acneform rush

TUMOR-ASSOCIATED LOCALIZED SCLERODERMA IN CONJUNCTION WITH ACQIRED DISSIMINATED FORM OF VITILIGO: A CLINICAL CASE

We are presenting the clinical and laboratory case of management of 62 years old patient with combined dermatological tumor-associated diseases: localized form of scleroderma, acquired disseminated form of hypopigmentation (vitiligo). The patient initial visit in a medical dermatological facility was due to the emergence of a consistent following complaints such as the sudden appearance of alterated skin sites in the left breast and some later the occurrence of rushes on the skin on the chest area and on the anterior surface of the abdomen. Upon further examination of the patient have been verified malignant tumor of the left breast, therefore appropriate (complex) treatment have been conducted in a medical institution of oncology service. After 1.5 years after the sectoral mastectomy the patient appealed to the dermatologist again with a complaints to the renewed activity of scleroderma process on the skin of the left breast. On the background of activation of dermatological symptoms the patient have been diagnosed recurrent tumor in the left breast. This clinical case is a multipurpose: first of all, it is demonstrates the importance of the principle of oncological vigilance in multidisciplinary daily medical practice which would improve early diagnosis and, consequently, treatment of the underlying disease; secondly, the present clinical case suggests an unexpected paraneoplastic contour of the diseases which are unpopular in this category previously, but generally frequent in the population

Genetic Effects at Pleiotropic Loci Are Context-Dependent with Consequences for the Maintenance of Genetic Variation in Populations

Context-dependent genetic effects, including genotype-by-environment and genotype-by-sex interactions, are a potential mechanism by which genetic variation of complex traits is maintained in populations. Pleiotropic genetic effects are also thought to play an important role in evolution, reflecting functional and developmental relationships among traits. We examine context-dependent genetic effects at pleiotropic loci associated with normal variation in multiple metabolic syndrome (MetS) components (obesity, dyslipidemia, and diabetes-related traits). MetS prevalence is increasing in Western societies and, while environmental in origin, presents substantial variation in individual response. We identify 23 pleiotropic MetS quantitative trait loci (QTL) in an F16 advanced intercross between the LG/J and SM/J inbred mouse strains (Wustl:LG,SM-G16; n = 1002). Half of each family was fed a high-fat diet and half fed a low-fat diet; and additive, dominance, and parent-of-origin imprinting genotypic effects were examined in animals partitioned into sex, diet, and sex-by-diet cohorts. We examine the context-dependency of the underlying additive, dominance, and imprinting genetic effects of the traits associated with these pleiotropic QTL. Further, we examine sequence polymorphisms (SNPs) between LG/J and SM/J as well as differential expression of positional candidate genes in these regions. We show that genetic associations are different in different sex, diet, and sex-by-diet settings. We also show that over- or underdominance and ecological cross-over interactions for single phenotypes may not be common, however multidimensional synthetic phenotypes at loci with pleiotropic effects can produce situations that favor the maintenance of genetic variation in populations. Our findings have important implications for evolution and the notion of personalized medicine

Polycyclic aromatic hydrocarbons in soils of industrial and residential areas of Tyumen

The relevance of the research is caused by the necessity to study the poorly investigated features of the priority polycyclic aromatic hydrocarbons accumulation in the urban topsoil of the city areas described by various functional purposes and industry. The main aim of the research is qualitative and quantitative assessment of the topsoil contamination in the residential and industrial areas of the city according to the polycyclic aromatic hydrocarbons composition and content observation. Objects of the research are urban topsoil undisturbed horizons (0-10 cm) of urban soils. Methods: soil sampling; methods for determining physical and chemical properties of soils, extraction of polycyclic aromatic hydrocarbons by saponification, high/performance liquid chromatography with fluorimetric detection using 1260 Infinity device made by Agilent (USA), statistical methods, calculation of diagnostic ratios of polycyclic aromatic hydrocarbons, hygienic and geochemical parameters. The results. The contents of 12 priority polycyclic aromatic hydrocarbons were determined in anthropogenically altered soils: naphthalene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenzo[a,h]anthracene, benzo[ghi]perylene. A wide variability of their content in urban topsoils is shown. It has been established that the increased contents of benzo[a]anthracene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene and benzo[ghi]perylene determine soil contamination in the residential area, and fluorene, phenanthrene, benzo[a]anthracene and benzo[k]fluoranthene - in the soils of industrial areas. It was revealed that, on average, the total content of polycyclic aromatic hydrocarbons is twice higher in the soils of the residential area than in the soils of industrial areas. This is due to both the physical and chemical properties of soils, and the duration and intensity of anthropogenic impact. An integrated assessment of pollution showed a dangerous level of soil pollution in the residential area, moderately dangerous - in the Antipinsky Refinery impact area and the permissible - in the CHP-2 plant impact area
