The analysis was based on the data on length of professional experience, localisation of rashes, clinical diagnoses and allergens, and the cause of positive reactions in epicutaneous testing. Pathological skin changes most often affected the upper limbs (hands, palms, fingers). As a diagnosis, the frequency of ACD was the highest – 79.4%, followed by that of dyshidrotic eczema (DE) – 17.6%, which also determines the highest percentage of dermatitis on the upper limbs (97%). Of the patients, 47.1% had a history of the disease for up to one year. For manicurists, the results of patch tests with the specialised MH-1000 series showed the highest frequency of positive reactions to 2-Hydroxyethyl methacrylate (2-HEMA) and 2-Hydroxypropyl methacrylate (2-HPMA) – 88.88% each, Ethylene glycol dimethacrylate (EGDMA) – 83.33% and 2-Hydroxyethyl acrylate (2-HEA) – 61.11%. After combining data for manicurists and clients, correlation analysis found a significant effect on the development of ACD to 2-HPMA (p=0.003) and EGDMA (p=0.005), as well as for hand dermatitis to 2-HEMA (p=0.05) and 2-HEA (p=0.044).</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00252023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0023<abstract> <title style='display:none'>Summary</title> <p>The choice between mechanical and bioprosthetic aortic valve implants is affected by relatively clear criteria. However, the choice between porcine or pericardial valve is more complex regarding bioprosthetic devices. We aimed to elucidate any hemodynamic and clinical difference between two widely used bioprosthetic valves: the Sorin Mitroflow bovine pericardial valve and the St. Jude Medical Epic Supra porcine valve. We retrospectively studied 71 consecutive patients separated into two groups based on the valve they received. Clinical outcomes included patient survival and hemodynamic performance of the implanted prostheses. Patients were assessed at one and five years postoperatively. Mean transprosthetic pressure gradients were used as a marker of hemodynamic performance. The Mitroflow valve exhibited lesser mean transvalvular gradients than the Epic valve for all labelled sizes at one and five years postoperatively. The 5-year survival was equal between groups. Both prostheses demonstrated a small but significant increase in mean pressure gradients in the fifth year. Most patients enjoyed significant clinical improvement as assessed by NYHA functional class. Both bioprostheses performed very well with excellent hemodynamic parameters. The pericardial valves are a safe and appropriate choice for surgical bioprosthetic aortic valve replacement.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00232023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0013<abstract> <title style='display:none'>Summary</title> <p>The administration of antenatal corticosteroids (ACS) to accelerate fetal lung maturation is considered one of the most valuable antenatal therapies in preterm labour. Although early indications that administering antenatal corticosteroids has a positive impact on fetal lung maturation and despite the widespread recommendations to use this treatment in women at risk of preterm birth, there is still some uncertainty regarding its effectiveness, particularly in lower-resource settings and in high-risk groups such as women with hypertension or multiple pregnancies. The optimal timing of administration has not improved in over 50 years. This assessment aimed to evaluate the effects of administering a course of corticosteroids to women before anticipated preterm birth (before 37 weeks of pregnancy) on fetal and neonatal morbidity and mortality, maternal mortality and morbidity, and the child’s health later in life. It is advised that clinicians only administer a single course of ACS in high-risk cases of preterm birth likely to occur within the next seven days, and the gestational age is between 22+0 and 33+6 weeks. The diagnosis of preterm labour should be made based on available resources and expertise and supported by comprehensive protocols in the relevant setting.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00132023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0017<abstract> <title style='display:none'>Summary</title> <p>Our study aimed to determine and analyze the serum levels of 25 (OH) vitamin D and parathyroid hormone (PTH) to assess vitamin D deficiency as a risk factor for increased morbidity of acute respiratory infections (ARI) in childhood. The changes in the serum parathormone level were used as a criterion for vitamin D sufficiency since an optimal level of 25 (OH) vitamin D is required for normal PTH values. The study included 87 children divided into four subgroups, respectively – children with acute bronchopneumonia (n=49), children with acute laryngotracheitis (n=11), children with acute bronchiolitis (n=16), and a control group (n=11). Subnormal Vit. D levels were found in the individual groups: in the bronchopneumonia group, 18 children showed evidence of insufficiency; in the group of children with laryngotracheitis, five children showed insufficiency, and one child had Vit.D deficiency; children with acute bronchiolitis showed abnormalities in vit. D levels: seven children with insufficiency and two children - with deficiency. The preliminary results showed that Vit.

The results showed that the serum erythropoietin level varied from 1.86 to 48.50 U/l and was below the borderline in only three patients. There were no significant differences between serum erythropoietin and haemoglobin values in both genders. No differences were found between the average haemoglobin values of patients with different values of serum erythropoietin. Non-significant differences were found in the values of serum erythropoietin in patients with different haemoglobin values. A statistically significant difference between the average value of serum erythropoietin was seen in the group of patients who were not undergoing treatment for anaemia with recombinant erythropoietin (8.5±5.9 U/l) and the groups treated with a dose above 3000 UI/weakly (from 18.6±11.3 to 19.7±8.8 U/l).</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00182023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0014<abstract> <title style='display:none'>Summary</title> <p>Two periods adjacent to starting dialysis are called “chronic kidney disease - peridialysis.” The predialysis period is of varying duration, while the dialysis period lasts up to 3 months after the first dialysis session.

The study aimed to analyse clinical, laboratory, and imaging indicators that have the strongest relationship with the presence of gangrenous cholecystitis and perforation of the wall and to design a predictive scoring system that highlights the risk of developing gangrenous cholecystitis with perforation. We performed a retrospective analysis of a total of 331 patients operated for five years (2016-2020) at the Department of Surgical Diseases” of Medical University - Pleven, with histologically verified chronic cholecystitis (120 patients; 36.4%), acute cholecystitis (100 patients; 30.1%), and destructive cholecystitis (111 patients; 33.5%).

A disturbed barrier function facilitates antigen penetration through the skin, with the subsequent development of allergic contact dermatitis (ACD). The gold standard for diagnosing ACD is epicutaneous (patch) testing, also applied to objectify contact sensitization in AD. This study aimed to determine the frequency of contact allergy (CA) among individuals with atopic history and the allergens that caused ACD in those cases. We studied 453 individuals tested in the period 2009-2022. Of these, a subpopulation of 189 individuals with atopic diathesis was identified. A retrospective analysis was used. Using clinical and allergological methods, we divided the tested patients according to sex, age, professional occupation, and areas of the body affected by dermatitis and identified the most common contact allergens that cause positive reactions and ACD. In conclusion, our results highlight the possibility of developing ACD in people with atopic diathesis. As far as we know, our study is the first one in Bulgaria to examine the frequency of contact sensitization in AD patients.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00262023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0016<abstract> <title style='display:none'>Summary</title> <p>The aim of this study was to determine the potential of early inflammatory markers to diagnose late-onset neonatal sepsis – interleukin 6 (IL-6), interleukin 8 (IL-8) and endocan (ESM-1), and to compare them with routinely used markers like C-reactive protein (CRP) and procalcitonin (PCT). A prospective (January, 2022 – January, 2023) clinical-epidemiological study was conducted in a third level NICU in Pleven, Bulgaria. Patients with suspected nosocomial infection and healthy controls were tested. A sandwich ELISA method was used to measure the serum concentrations. Sixty newborns with an average gestational age of 29.75±3.61 gestational weeks were included, of which 35% were symptomatic and infected, 33.3% were symptomatic but uninfected, and 31.7% were asymptomatic controls. The mean values of PCT and IL-6 differ significantly in the three groups. For ESM-1, IL-8 and CRP, the difference was statistically insignificant. The best sensitivity (78%) and negative predictive value (84%) was found for IL-6. The introduction into routine practice of indicators such as PCT and IL-6 may provide an opportunity to promptly optimize the diagnostic and therapeutic approach to LOS.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00162023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0021<abstract> <title style='display:none'>Summary</title> <p>Hepatobiliary sepsis and biliary septic shock are defined as a group of purulent-inflammatory diseases of the biliary tract which, in their progression, lead to sepsis in case of delayed diagnosis and treatment. The study aimed to analyse all the cases of hepatobiliary sepsis treated at the Clinic of Surgery, Dr G. Stranski University Hospital – Pleven, from 2016 to 2020 and create a reliable prognostic score for surveillance for patients with hepatobiliary sepsis. Retrospectively, we analysed the records of 697 patients (81%) with a hepatobiliary tract infection, including 79 (11.3%) diagnosed with hepatobiliary sepsis and six fatal cases (1.3%). We evaluated all statistically significant factors that affected mortality: immune deficiency comorbidity (р&lt;0.005), pathogenesis-related to trauma and ascending biliary tract infection (p&lt;0.005), positive hemoculture (p&lt;0.001), length of hospital stay, the need of treatment in intensive care unit and all septic complications. We designed four different prognostic indices based on calculated individual SOFA scores and factors that significantly affected mortality in the high SOFA score patients: immune deficiency, pathogenesis-related risks of sepsis or positive blood culture. The newly designed indices for the outcome are original and have 80% sensitivity and 87% specificity, compared with a simple SOFA score.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00212023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0015<abstract> <title style='display:none'>Summary</title> <p>The current study aimed to evaluate the influence of Japanese quince (Chaenomeles japonica) fruit juice (JQFJ) on the myocardium and on the coronary arteries of rats with diet-induced metabolic syndrome (MS). Male Wistar rats (n=50) were divided into 5 groups: Control, MS, MS+JQFJ2.5, MS+JQFJ5 and MS+JQFJ10. MS was induced with a high-fat high-fructose diet for 10 weeks. During that period, all animals were daily orally treated with distilled water (Control and MS groups) or with JQFJ at doses of 2.5 ml/kg, 5 ml/kg and 10 ml/kg (the other three groups, respectively). At the end of the experiment, the myocardium and coronary arteries were examined histopathologically. In group MS, necrotic endothelial cells and exposed basal membrane were observed. JQFJ at 2.5 ml/kg reduced the impairment but activated endothelial cells were still found. JQFJ at 5 ml/kg and 10 ml/kg prevented coronary artery endothelium damage, preserving the normal morphology. The myocardium in MS group presented with cardiomyocyte degeneration and increased distance between the cells. In group MS+JQFJ2.5, the degeneration was decreased. In groups MS+JQFJ5 and MS+JQFJ10, the histology of the myocardium resembled that of the control group.

We aimed to present the initial experience with stereotactic vacuum-assisted biopsy in breast diseases at the Department of Surgical Oncology. We show indications and contraindications for this kind of biopsy and present our initial experience. From February 2020 to December 2022, 29 stereotactic vacuum-assisted biopsies were performed. Benign histology was found in 9 cases, malignant – in 15, and 5 cases were precancerous. Therefore, being an innovative, minimally invasive, and highly accurate method for diagnosing breast lesions with a good cosmetic effect, it allows early diagnosis of breast cancer, and, last but not least, the procedure can be curative for benign lesions.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00222023-12-11T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0019<abstract> <title style='display:none'>Summary</title> <p>The purpose of оur research was to evaluate the effect of remote education on ocular health among medical students during the current COVID-19 pandemic.

They were interviewed anonymously, with an online questionnaire, between April 1-30, 2021. The findings of the study highlighted that digital learning increases screen time, at potentially dangerous for eye health levels. The most common presenting complaints were eye fatigue (83.1%), tearing (epiphora) (58.9%), dry eyes (58.4%), blurred vision (40.2%), photophobia (37.4%), itchiness (34.7%) etc. Regarding the longest uninterrupted time spent working on a computer, 32% of the students reported 1-2 hours without a break, 57.1% - more than 2 hours, and only 3.7% spent less than 20 min before taking a break. As the conclusion of this study, it was observed that distance learning during the pandemic and social isolation adversely affected eye health and eye fatigue among medical students.

We rated the age- and sex-related incidence, risk factors, localisation, pathological features, staging systems and treatment, and the recurrence and mortality rates of the tumours. Staging and risk stratification for recurrence and metastases is significant. Most SCCs are successfully treated surgically, with a small subset of carcinomas leading to recurrence, metastasis, and death.

Two generally accepted endoscopic approaches are transabdominal preperitoneal procedure (TAPP) and total extraperitoneal procedure (TEP). For nine years (2010 – 2018), 48 patients with inguinal hernia had laparoscopic hernia repair (TAPP or TEP) at Villarobledo General Hospital. Forty-three patients (89.6%)) were male, and five (10.4%) were female. Of these, ten had right inguinal hernia (RIH), 18 - left inguinal hernia (LIH), 12 - bilateral inguinal hernia (BIH), 6 had recurrent unilateral inguinal hernia (RUIH), and 2 had recurrent bilateral inguinal hernia (RBIH). In 33 patients (68.7%), transabdominal preperitoneal laparoscopic hernia repair (TAPP) was performed. Total extraperitoneal laparoscopic hernia repair (TEP) was performed on 15 patients (12%). In 8 patients (16.6%), simultaneous surgical procedures were performed: umbilical hernioplasty in 4 (8.3%) patients and laparoscopic cholecystectomy in 4 (8.3%) patients. There were no conversions in any of the surgical procedures. The average operative time was 77 minutes. Twenty-six patients underwent one-day surgery, 18 were in the hospital for one day, and four patients were discharged on the second postoperative day following surgery. In 7 patients (14%), recurrences occurred: in the first postoperative year - 1 patient; in the second year after surgery - 3 patients; in the third after surgery - 2 patients; and in the sixth year - 1 patient. The recurrence rate was 2 in 33 patients after TAPP (6%) versus 5 in 15 patients after TEP (33%), Chi-squared=5.91 (p=0.015). In one patient, perforation of the bladder occurred after TEP and was managed conservatively using a urethral catheter and preperitoneal drainage. TAPP and TEP had a considerable discrepancy in recurrence rates. Such discrepancy in recurrences is probably due to the higher complexity of the TEP technique and the required supervising of experienced surgeons during the learning curve.</p> </abstract>ARTICLEtruehttps://sciendo.com/article/10.2478/jbcr-2023-00052023-08-10T00:00:00.000+00:00https://sciendo.com/article/10.2478/jbcr-2023-0011<abstract> <title style='display:none'>Summary</title> <p>Acute aortic dissection is an extremely serious condition with a high mortality risk.
