According to research in Russia in 2016, the prevalence of diseases of the skin and subcutaneous tissue was 5871 cases per 100000 people, the incidence was 4259 cases per 100000 people. Severe chronic dermatoses significantly reduce the quality of life of patients and their families, the patients’ self-esteem suffers, their habitual lifestyle is disturbed. The purpose is to study the level dynamics and structure of the incidence of diseases of the skin and subcutaneous tissue of the population of the Republic of Bashkortostan for the period 2008-2017. The analysis of the structure and dynamics of the prevalence and the incidence of the ICD-10 class “Diseases of the skin and subcutaneous tissue” (L00-L99) in the Republic of Bashkortostan was carried out according to the FSN form No. 12 for 2008-2017, and a simulated forecast of the incidence rate up to 2022 was compiled. The study revealed a steady downward trend in the prevalence and the incidence of these diseases in the Republic of Bashkortostan for the period 2011-2017. Considering the prediction data, the trend towards a decrease in the incidence rates of skin diseases until 2022 will continue. On this background, the level of the prevalence of atopic dermatitis and psoriasis tends to increase, the incidence of atopic dermatitis tends to increase, and the incidence of psoriasis tends to decrease. The proportion of severe chronic dermatoses increased 1.5-2 times in all age groups. Thus, the analysis makes it necessary to improve the work on the organization of medical care for patients with chronic dermatoses and methods for their prevention.

AbstractInjectable fillers represent one of the most requested minimally invasive treatments to rejuvenate the aging face, and its popularity is steadily rising. A vast majority of filler treatments are with hyaluronic acid (HA). The aim of this systematic review is to evaluate patient outcomes, safety profile, and administration techniques of various HA fillers for malar augmentation. A systematic review of the published literature was conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and included PubMed, Embase, and Science Direct databases. Medical Subject Headings (MeSH) terms used were “cheek” OR “midface” OR “malar” and “filler” OR “hyaluronic acid” OR “Juvederm” OR “Restylane” OR “Perlane” OR “Belotero.” The initial search identified 699 articles; 256 duplicates were removed. Additional 12 studies were identified from reference lists. A total of 455 were screened by title and abstract and 387 studies were eliminated based on criteria. Also, 68 articles underwent full-text review, and 18 articles were included in the final review and involved seven different HA formulations. Men and women from many age groups were highly satisfied with their results following HA treatment for midface augmentation up to 24 months. The most common adverse events included bruising, swelling, and tenderness, and typically lasted no more than 2 weeks. Upper cheek filler injections near the zygoma should be placed in the submuscular plane while lower cheek injections should be placed in the subcutaneous tissue. HA is an attractive choice for midface augmentation due to its high patient satisfaction, long-lasting effects, and low side-effect profile. Due to the variability in technique, level of expertise, and subjective measurements across studies, one optimal regimen could not be concluded. However, midface augmentation treatment should be personalized to each patient. Additional clinical trials are required to more conclusively determine the most appropriate approach for this procedure.

ABSTRACT Background: The evaluation of collagen in the abdominal wall has been increasingly studied because of the relevance on collagen in the healing process after laparotomy. Aim: To evaluate the amount of collagen in the linea alba of patients undergoing laparotomic bariatric surgery and comparing with non-obese cadavers. Methods: Were evaluated 88 samples of aponeurosis from abdominal linea alba of 44 obese patients (obesity group) and 44 non-obese cadavers (control group). The samples were collected in 2013 and 2104, and were sorted according to age (18-30, 31-45 and 46-60), gender, BMI, waist and cervical circumference, and subcutaneous tissue thickness. Material for biopsy was collected from the supraumbilical region of the linea alba for immunohistochemical analysis differentiating collagen type 1 and type 3 and the 1/3 ratio. Image-Pro Plus pixel counting software was used to measure the amount of collagen. Results: The obesity group evidenced mean age 44.11±9.90 years; 18-30 age group had three (6.8%) obese individuals; 31-45 had 22 (50%) and 46-60 had 19 (43.1%). Females were present in 81.8% (n=36); BMI (kg/m²) was 48.81±6.5; waist circumference (cm) was 136.761±13.55; subcutaneous tissue thickness (cm) 4.873±0.916. Considering age groups, gender and BMI, there were statistical differences in all tests when compared with the cadavers. Conclusion: The amount of collagen in the linea alba above the umbilical region in the morbidly obese patients was smaller than in the non-obese cadavers in the same age group.

Small Resistance

Nitric oxide (NO) is produced by endothelial NO synthase (eNOS) using the aminoacid L-Arginine. Arginase (Arg) also uses L-Arginine as substrate, converting it in L-Ornitine and urea. An increased Arg activity causes a progressive L-Arginine depletion, which in turn determines a lower NO bioavailability. Studies in murine models of obesity identify Arg as a determinant of endothelial dysfunction. In this study, we evaluated whether Arg might play a role in determining the lower bioavailability of NO in small resistance arteries isolated from subcutaneous tissue of patients with severe obesity (Ob), split in age groups (younger than 30 aa, range 21-29, n=5; older than 30 aa, range 35-56, n=5) vs normoweight controls (Ctrl younger 30 years, range 20-29, n=5; older than 30 yrs, range 36-58, n=5). Each patient underwent a subcutaneous biopsy during a laparoscopic surgical procedure. Small arteries, isolated from periadvential fat, were evaluated on a pressurized micromyograph. Endothelium-dependent vasodilation (VD) was assessed by acetylcholine (Ach, 0,001-100μM). NO availability was assessed by repeating Ach with L-NAME (100μM). Ach was also infused in the presence of norNOHA (10μM, Arg inhibitor). In Ctrl, VD induced by Ach was inhibited by L-NAME and not modified by norNOHA. Ob younger exhibited a reduced VD induced by Ach vs Ctrl of the same age, a reduced inhibition by L-NAME, and a potentiating effect by norNOHA, which also normalized the inhibitory effect of L-NAME on Ach. In Ob older, VD induced by Ach was reduced vs Ob younger, resistant to L-NAME and not modified by norNOHA. In conclusions, in small arteries from younger Ob, the Arg inhibition improves endothelial function by increasing the NO availability, while in older Ob Arg does not seem to play any role in endothelial dysfunction.

ObjectiveDescribe the pattern of atopic disease prevalence from infancy to adulthood.DesignCross-sectional household survey.SettingCommunity-based demographic surveillance site, Mirzapur, Bangladesh.Participants7275 individuals in randomly selected clusters within 156 villages.Primary and secondary outcome measuresThe 12-month prevalence of atopic dermatitis (by UK Working Party Criteria (UK criteria) and International Study of Asthma and Allergies in Childhood (ISAAC)), asthma and rhinitis (by ISAAC); disease severity (by ISAAC); history of ever receiving a medical diagnosis.ResultsChildren aged 2 years had the highest prevalence of atopic dermatitis—18.8% (95% CI 15.2% to 22.4%) by UK criteria and 14.9% (95% CI 11.6% to 18.1%) by ISAAC— and asthma (20.1%, 95% CI 16.4% to 23.8%). Prevalence of rhinitis was highest among 25–29 year olds (6.0%, (95% CI% 4.5 to 7.4%). History of a medical diagnosis was lowest for atopic dermatitis (4.0%) and highest for rhinitis (27.3%) and was significantly associated with severe disease compared with those without severe disease for all three conditions (atopic dermatitis: 30.0% vs 11.7%, p=0.015; asthma; 85.0% vs 60.4%, p<0.001; rhinitis: 34.2% vs 7.3%, p<0.001) and having a higher asset-based wealth score for asthma (29.7% (highest quintile) vs 7.5% (lowest quintile), p<0.001) and rhinitis (39.8% vs 12.5%, p=0.003). Prevalence of having >1 condition was highest (36.2%) at 2 years and decreased with age. Having atopic dermatitis (ISAAC) was associated with significantly increased odds ratios (OR) for comorbid asthma (OR 5.56 (95% CI 4.26 to 7.26)] and rhinitis (3.68 (95% CI 2.73 to 4.96)). Asthma and rhinitis were also strongly associated with each other (OR 8.39 (95% CI 6.48 to 10.86)).ConclusionsAtopic disease burden was high in this rural Bangladeshi population. Having one atopic condition was significantly associated with the presence of another. Low incidence of ever obtaining a medical diagnosis highlights an important opportunity to increase availability of affordable diagnosis and treatment options for all age groups.

Abstract Background Pediatric classical Hodgkin lymphoma (cHL) is a clonal disorder in an inflammatory background, also known as the microenvironment. This microenvironment is of major importance for growth and survival of the malignant Hodgkin/Reed Sternberg (HRS) cells. HRS cells and the microenvironment communicate through chemo- and cytokines. Blood biomarkers result from this active crosstalk, and may be a surrogate for lymphoma viability (Steidl et al, JCC 2011). Blood biomarkers are important because they hold the promise to be easily available and cost-effective. One promising biomarker in adult patients with cHL is the "Thymus and Activation-Regulated Chemokine, TARC (Plattell et al, Haematologica 2012). Elevated TARC levels are also described in patients with atopic dermatitis (Hijnen et al, J All Clin Immunol 2004). In adult cHL patients about 85% of patients have significantly elevated levels of TARC in pre-treatment serum or plasma compared to healthy controls (Plattell et al). So far nothing is known about TARC in pediatric cHL patients. To define its value as a diagnostic marker in pediatric cHL patients, we compared TARC levels of pediatric cHL patients with control patients. This study was IRB-approved and registered under Dutch Trial registry number 6876. Methods After providing informed consent, plasma and serum samples were collected of newly diagnosed cHL patients before start of treatment. To define normal values of TARC in children, samples were collected from non-cHL randomly selected patients from the hematology, endocrinology and oncology outpatient clinic. Baseline characteristics including history of atopic dermatitis were collected. These control patients were divided in three age groups (0-9,10-14 and 15-18 years). TARC levels were measured by enzyme-linked immunosorbent assay (R&D systems, Human CCL17/TARC Quantikine ELISA Kit). TARC levels of the cHL patients were compared to the control group to obtain ROC curves and calculate the AUC, cross-validated sensitivity and specificity and accuracy of TARC as a diagnostic marker. We hypothesized that pediatric cHL patients had elevated pretreatment TARC levels in both serum and plasma. Analyses were done using SAS V9.4. Results Fourteen cHL patients were included with a median age of 14 (range 11-17) years. Ten (71.4%) were female. Eighty patients were included in the control group with a median age of 12 (range 10 months-18) years. Twenty-nine patients (36.3%) were included in age group 0-9, 25 (31.2%) in age group 10-14 and 26 (32.5%) in age group 15-18. Thirty-nine (48.8%) were female. Patients of the control group had a median TARC value of 71 (range 18-762) pg/ml for plasma and 318 (range 27-1300) pg/ml for serum. TARC plasma and serum levels decreased with age (Spearman correlation -0.26, 2-tailed p=0.0204), but there were no statistically significant pairwise comparisons found between the pre-specified age groups. In the eight control patients (10%) with atopic dermatitis no significantly higher plasma and serum levels were found (plasma median with eczema 97 versus 70 pg/ml without eczema (p=0.71) and serum median with eczema 643 versus 317 pg/ml (p=0.71)). Plasma was collected in 14 cHL patients, and all had elevated TARC levels, with a median plasma level of 18449 (range 1635-55821) pg/mL. Serum samples were collected in 8/14 cHL patients and all had elevated serum TARC levels. Median serum level: 46703 (range 12817-149739) pg/ml. The plasma TARC levels of cHL patients were significantly higher than those of the control group patients (p<0.001). With a cut-off of level of of 898.70 pg/ml, we obtained 100% (95% CI 73% - 100%) sensitivity and 100% (95% 94% - 100%) specificity. Serum TARC levels also were significantly higher than those of the control group patients (p<0.001), with a cut-off level of 10283.57 pg/ml, sensitivity and specificity will be 100% (95% CI 60% - 100% for sensitivity and 95% CI 94% - 100% for specificity). Conclusion All classical cHL patients had significantly higher TARC levels compared to the 80 control patients. Despite the small sample size of cHL patients, TARC was found to be a sensitive and specific diagnostic marker for pediatric cHL in both plasma and serum. Further research with a bigger sample of cHL patients is necessary to improve the accuracy of the sensitivity, as well as to investigate whether TARC is also a valuable marker for disease response during treatment in pediatric patients with cHL. Disclosures No relevant conflicts of interest to declare.

Background. Atopic dermatitis (AD) is the most common allergic disease among children of young age. Severe forms of AD with skin bacterial and fungal overgrowth may be associated with features of the immune response in different age groups. Plenty of studies demonstrated not only polarization of the Th2 immune response in AD patients, but also the Th1 immune dysregulation. The purpose of this study was to investigate the features of the immune response in children with varying severity of atopic dermatitis. Materials and methods. The study included 85 children aged 3 months to 3 years with a verified diagnosis of AD, living in the Zaporozhzhia region. Twenty healthy children without atopy formed a control group. The patients were divided into groups depending on the severity of AD based on the SCORAD scale. The serum levels C3, C4–2, CD3+, CD19–, CD4+, CD8–, CD4–, CD8+, CD3–, CD56+, CD19+, CD14, CD45, IgA, IgM, IgG, IgE, С3, С4–2, phagocytic acti­vity of neutrophils, and proliferative activity of lymphocytes were measured by flow cyto­metry (Synevo). ELISA method was used to detect serum levels of IL-13 (ELISA Kit, Thermo Fisher Scientific, Austria). Statistical processing of the results was performed using the official software package Statistica 13.0. Results. The study revealed eosinophilia in 60 % of the children with a mild and moderate course of AD (Me 5.62 [3.64; 7.81]) and in 56 % of the children with a severe course (Me 6.18 [3.13; 9.42]). The children with a severe course of AD and low levels of IL-13, C3 had transient hypogammaglobulinemia and significantly lower le­vels of the C3 complement, increased levels of CD4+, CD8– with simultaneously decreased levels of CD4–, CD8+ compared with groups of the children with high levels of ­IL-13 (р < 0.05). Conclusion. The results suggest that severe forms of AD in children of the young age were associated with changes in the complement system and low levels of cytotoxic cells, transient hypogammaglobulinemia. It requires deeper research of the cascades of the immune response in children with AD.

Abstract IntroductionVaccination features high among the public health interventions that have contributed significantly to global health. Following the March 2020 declaration by the World Health Organization that coronavirus 2019 (COVID-19) is a global pandemic, several vaccines have been developed and administered to curb the spread of COVID-19. One of the threats to attaining adequate vaccination uptake for these relatively new vaccines are concerns people have about the adverse event following immunization (AEFI) information. This study sought to assess AEFIs reported on COVID-19 vaccines approved for use so far in VigiAccess and to make a case for why AEFIs data in the database must be interpreted with caution.MethodsThe study followed a cross-sectional quantitative study design. VigiAccess was searched on November 10, 2021 for AEFIs reported so far for all the 12 approved COVID-19 vaccines. Data were captured among age groups, sex and continents of the world. Descriptive data were summarized using tables. Frequencies and percentages were used to categorize descriptive variables. No ethical approval was obtained before the commencement of the study as this was essentially a secondary data analysis of AEFI reports which cannot be linked to any individual. Consequently, there was no need for the informed consent process.ResultsOverall, 2,457,386 AEFIs had been reported in VigiAccess. AEFIs were found to be highest among the 18-44 age group (39.7%) and lowest in vaccine recipients below 12 years (0.1%). AEFIs were more common in females than male vaccine recipients with over two-thirds of the vaccine recipients being females. Among the continents of the world, AEFI reports were highest for Europe (50%) and lowest for Africa (3%). The top 10 commonly reported AEFI types were as follows: general disorders and vaccine administrative site conditions (1,481,549, 60.1%), nervous system disorders (1,046,928, 42.6%), musculoskeletal and connective tissue disorders (704,657, 28.6%), gastrointestinal disorders (495,997, 20.2%), investigations with undesirable outcomes (341,677, 13.9%), skin and subcutaneous tissue disorders (335,932, 13.6%), respiratory, thoracic and mediastinal disorders (262,158, 10.6%), infections and infestations (180,873, 7.3%), vascular disorders (132,533, 5.3%) and injury, poisoning and procedural complications (122,519, 5%).ConclusionThe study showed that over 2 million COVID-19 AEFIs were spontaneously reported in VigiAccess, however, no causal relationships could be established between the vaccines and the AEFIs. The public accessing VigiAccess data should be made aware of this lack of association so that they may make well informed health decisions.

Aim: Food-induced anaphylaxis is most common in the paediatric population and has an unpredictable course. The aim of this paper was to perform a demographic and clinical assessment of food-induced anaphylaxis in children using molecular diagnosis. Materials and methods: The study included 541 children aged 0–18 years who developed 893 sudden reactions to food. Levels of IgEs against 112 allergen molecules were measured in each child. We analysed demographic and clinical data in two age groups. The aetiology of anaphylaxis was determined at the level of source allergens and at the level of allergen molecules. We also determined the risk factors for severe clinical course of reactions. Results: A total of 631 food-induced anaphylactic reactions developed by 421 children were included in the analysis. The group of children aged 0–6 years was mostly composed of boys (p = 0.0023) and children with atopic dermatitis (p = 0.0001). Also, cutaneous and mucosal symptoms were more common (p < 0.0001), and milk casein, Bos d 8, was the most common cause of anaphylaxis in this group (p < 0.0001). In the group of 7–18-year-olds, anaphylaxis was more common in children with no asthma or atopic dermatitis (p = 0.0001); hazelnuts (p = 0.0005) and, in terms of allergen molecules, walnut 2S albumin, Jug r 1 (p = 0.0011), were a more common cause of reaction; as well as exercise-induced anaphylaxis (p < 0.0001) and cardiovascular symptoms (p = 0.0247) were more common. In the study population, more severe anaphylaxis was more common in children without asthma or atopic dermatitis (p = 0.0428) and in the case of anaphylaxis induced by cashew nut 2S albumin, Ana o 3 (p < 0.0001) and wheat allergen, Tri a 14 (p = 0.0143). Conclusions: Molecular diagnostics allows for a detailed assessment of the aetiology and the risk of severe food-induced anaphylaxis.
