By researching the factors related to exposure to indoor and outdoor allergens, such seasons, climate changes and particulate matter, allergists can screen the sensitization profile of individuals according to their exposures and conduct preventive treatment and individualized immunotherapy. Molecular allergology has improved aerobiological screening of allergenic components toward more specific results on allergic exposure, sensitization, and symptoms [1,2]. The Enzyme-Linked Immunosorbent Assay (ELISA) is a colorimetric enzyme immunoassay technique used to quantify soluble substances such as proteins, peptides, antibodies, and hormones. Due to its high sensitivity and specificity, ELISA can quantify substances at low concentrations, such as allergens [3].

Oral lichen planus (OLP) is an autoimmune chronic inflammatory disease. The potential risk of malignant transformation in OLP remains controversial. The aim of the present study was to review original clinical studies published in indexed databases, which assessed the potential risk cofactors which were implicated in the malignant transformation of oral lichen planus. We focused our search to include most of the studies that reported malignant transformation of oral lichen planus using different combinations of the following key indexing terms: oral lichen planus, malignant transformation, smoking, alcohol, chronic inflammation, candida, human papillomavirus (HPV), hepatitis C virus (HCV) and immunosuppression. The animal studies were excluded from our study. Despite a dearth of studies on this topic we have identified consumption of tobacco and/or alcohol, the presence of erosive and/or atrophic areas, infection with candida, HCV, HPV, and immunosuppression as significant cofactors. Patients with OLP with these risk co-factors are at risk of malignant transformation should, therefore be followed up for an extensive period or even for life.

Background: Rotation of the femoral component in total knee replacement (TKR) is very important for good long-term results. Malrotation of the femoral component usually requires subsequent reimplantation. We performed X-ray projections of the knee at 90° to determine proper rotation of the femoral component without use of computed tomography. Methods: The axial projection of the distal femur was measured in post-TKR cases. During the TKR operation, Whiteside’s method had been used to provide symmetrical flexion space. The exact outer rotation of the femoral component was measured by x-ray determination of the middle condylar twist angle, from the central epicondylar axis and posterior condylar axis. Results: The middle condylar twist angle was in outer rotation, with an average of 3.36° (range: 1-7.6), similar to the literature. Six of the patients underwent bilateral TKR. In total, the case series included 18 women and 15 men, with average age of 71.34 years-old (range: 56-85). As a clinical evaluation we used Knee Society Score (2011). From results 2 patients were not very satisfied with the instability TKR. Axially X-ray seemed to be only which could distribute these patients. Summary: X-ray values have the same evaluation as computed tomography. The results were 2 patients in pattern of 48, which were sufficient to extrapolate to whole population according to the statistical methods. This corresponds to 4% which we can add to evaluate satisfaction of all patients after TKR and eventually lower the total of unsatisfactory patients which is total of ¼ of total. It is also forensic reason for all patients. Our recommendation to have good results and patient satisfaction in TKR is to do x-rays before and after operation. Important are x-rays antero-posterior, lateral, and Kanekasu projection to know the rotation after TKR. Other cases without stability in flexion are nor very rarely planed for revision surgery, which is much more expensive, and burdens overall health system. 

The aim of this study was to investigate and compare the complications including infection and mortality associated with enteral and parenteral nutrition on patients in the ICU of a university hospital. In this study, a total of 100 patients who were under follow-up in the ICU for two years were examined. In our study, demographic characteristics, the reason for admission, comorbidity, initial ICU laboratory values, morbidity and mortality during the follow-up period of the patients who only received enteral nutrition (EN) or parenteral nutrition (PN) were evaluated, and the results between two were compared as well as evaluating the complications within the groups. The comparison of the reason for admission between the EN and PN groups showed that surgical reasons were significantly higher in the PN group. Nosocomial infections, the presence of infection and the development of sepsis were significantly higher in the EN group. The 28-day mortality rate was higher in the PN group compared to the EN group. The length of stay in the ICU and on mechanical ventilation was longer in the EN group. There was no significant difference in the 28-day mortality, readmission to the ICU and repeated endotracheal intubation between the two groups. Because there is no statistical difference between EN and PN groups in point of infection and mortality, we conclude that the length of stay in the ICU and reason for admission play a more crucial role in the development of infection and on mortality rather than enteral or parenteral nutrition route.

Objective: Plaque morphology plays an important prognostic role in the occurrence of cerebrovascular events. Echolucent and heterogeneous plaques, in particular, carry an increased risk of subsequent stroke. Depending on the quality of the plaque echogenicity based on B-mode ultrasound examination, carotid plaques divide into a soft lipid-rich plaque and a hard plaque with calcification. The aim of this study was to investigate structural changes in the basement membrane of different carotid artery plaque types. Patients and methods: Biopsies were taken from 10 male patients (average age; 75 + 1 years) and 7 females (68 + 3 years). The study population included patients suffering from a filiform stenosis of the carotid artery, 8 patients with acute cerebrovascular events and 9 with asymptomatic stenosis. Scanning electron and polarised light microscopic investigations were carried out on explanted plaques to determine the morphology of calcified areas in vascular lesions. Results: By means of scanning electron microscopy, multiple foci of local calcification were identified. The endothelial layer was partially desquamated from the basement membrane and showed island-like formations. Polarised light microscopy allows us to distinguish between soft plaques with transparent structure and hard plaques with woven bone formation. Conclusion: The major finding of our study is the presence of woven bone tissue in hard plaques of carotid arteries, which may result from pathological strains or mechanical overloading of the collagen fibers. These data suggest a certain parallel with sclerosis of human aortic valves due to their similar morphological characteristics.

Aim: The purpose of this study was to evaluate the effect of Titanium dioxide and Gold nanoparticles surface treatment on the flexural strength of Polymethyl methacrylate (PMMA) Heat cure denture base resins.Materials and methods: A total of thirty PMMA Heat cure denture base resin test samples were fabricated of size 65 x 10 x 2.5 mm (rectangular shaped) according to ADA specification no.2. The samples were divided into three groups as Conventional PMMA heat cure denture base resin samples (GROUP I, n = 10 CONTROL), PMMA Heat cure denture base resin samples coated with Titanium dioxide nanoparticles (GROUP II, n = 10) and PMMA Heat cure denture base resin samples coated with Gold nanoparticles (GROUP III, n = 10). GROUP II and GROUP III PMMA Heat cure denture base resin test samples were coated by Magnetron sputtering. Flexural strength of GROUP I, GROUP II and Group III was evaluated by a three-point bend test using a Universal testing machine and the mean values were obtained.Results: The Mean flexural strength of GROUP I, GROUP II and GROUP III samples were 114.79 MPa, 142.48 MPa and 154.70 MPa respectively. On comparative evaluation of the flexural strength among the three groups GROUP III PMMA Heat cure denture base resin samples exhibited the highest flexural strength followed by GROUP II and least by GROUP I. The statistical analysis by ANOVA had shown that there is significance in flexural strength among the groups tested (p - value = 0.000*).Conclusion: Within the limitations of the study, PMMA heat cure denture base resin coated with Gold nanoparticles showed the highest flexural strength followed by PMMA Heat cure denture base resin coated with Titanium dioxide nanoparticles. Conventional PMMA Heat cure denture base resin without any surface treatment showed the least flexural strength.

Background: The novel coronavirus is a rapidly spreading respiratory disease that has been declared a pandemic by the World Health Organization (WHO) and a global public health emergency. The use of face masks has been recommended by the WHO and the Centers for Disease Control (CDC) as a standard prevention method for transmission of COVID-19.Objective: The objective of this study is to determine face mask utilization and associated factors in combating the COVID-19 pandemic among government employees in Akaki district administration offices in Akaki District, Oromia, Ethiopia, 2022Methods: A quantitative cross-sectional study was conducted from December 1, 2021, to February 15, 2022, on 385 government employees working in Akaki district administration offices. After obtaining consent from the study participants, data were collected using pretested, self-administered, and standardized questionnaires adapted from other studies. After the data was collected, it was entered into Epi info version 7.2.6, cleaned, and analyzed using SPSS version 26. A logistic regression model was computed to measure the association between the predictor and outcome variables. A p - value of.05 with a 95% CI was used as the cut-off point to declare the level of statistical significance. Results: The study showed that the magnitude of good practice for facemask utilization was 213 (53.5%) (95% CI: 1.50, 1.60) for preventing COVID-19. In the multivariate logistic regression analysis, the odds of using face masks among male employees (AOR = 0.275; 95% CI: 0.137, 0.555), employees aged 20-29 (AOR = 0.17; 95% CI: 0.065, 0.481 ), employees aged 30-39 (AOR = 0.260, 95% CI: 0.109, 0.623), employees of less than five family size (AOR = 0.549, 95% CI: 0.303, 0.995), work experience at 6-12 (AOR = 0, 32, 95 CI: 0.120, 0.450), poor knowledge about face mask use (AOR = 0.504, 95% CI: 0.302, 0.844), and employees with a negative attitude (AOR = 0.430, 95% CI: 0.256, 0.721) were factors significantly associated with face mask utilization.Conclusion: The magnitude of facemask utilization was low (53.5%) compared to other studies. The results of the study showed that age, sex, household family size, work experience, poor knowledge, and the negative attitude of employees toward facemask utilization were among the factors significantly associated with facemask utilization.

Ischemic heart disease may occur in isolation, or in combination with the pathological process of vascular ageing, arteriosclerosis. These two conditions have differing impacts on the haemodynamic changes in response to anaesthesia and surgery. Hypertension is not a feature of ischemic heart disease, and vice versa, but where the two conditions co-exist, hypertension aggravates and accelerates the pathological processes of ischemic heart disease. Patients older than 40 yrs. presenting for anaesthesia and surgery must therefore be considered at risk of any combination of these three conditions. Anaesthetic techniques must also be chosen to minimize haemodynamic changes which in the normal healthy patient cause no serious morbidity, but which, in the patient with ischemic heart disease, can lead to serious morbidity or death. Here we report a 70 years old (BMI of 23.3) elderly, hypertensive Male patient with ischemic heart disease with previous MI (EF of 40% - 5%) undergoing elective Inguinal hernia repair. We Opted Spinal anesthesia over General anaesthesia as it should be an asset in cardiac patients undergoing non-cardiac lower abdominal surgeries to reduce preload and after load, stress response, coagulation responses, improves coronary perfusion, provides better postoperative analgesia, reduces incidence of perioperative MI, maintains myocardial oxygen supply demand ratio and avoids harmful effects of GA such as hypotention due to intravenous induction drugs, tachycardia and hypertension due to pressor response during direct laryngoscopy and tracheal intubation.

Solid tumor oncology treatments are primarily performed in the outpatient setting. However, hospitalizations are inevitable due to complications of cancer and treatment-related toxicities. With rising health care spending, the length of hospital stay (LOS) is increasingly considered a proxy for healthcare costs. There are several ongoing efforts to abbreviate the inpatient LOS and ensure a safe and timely discharge to the outpatient setting. In addition to the acute illness and the associated comorbidities, various factors affect the LOS: social determinants of health (SDOH), nutritional status in cancer patients, and end-of-life issues. Furthermore, it is unclear how the institutional policies on social distancing and visitation during the current coronavirus disease (COVID-19) pandemic may impact the LOS. The purpose of this article is to review various factors and barriers that lead to longer LOS for solid tumor patients during the COVID-19 pandemic, and identify the critical areas of quality improvement.

The study attempted to answer several questions: Does the cultural and social background of immigrant youth from the Former Soviet Union (FSU) affect their use of addictive substances? Do these youth show distinctive patterns of drug and alcohol abuse? Do the addictive substances used by these teenagers share similar characteristics? Are the patterns of drug abuse and alcohol abuse different? Do students in different educational frameworks demonstrate different consumption patterns? Can “critical moments” explain the presence or absence of alcohol and drug abuse?
