Coronavirus infections have caused outbreaks in humans: SARS-COV ((Severe Acute Respiratory Syndrome) and MERS-CoV (Middle East Respiratory Syndrome) resulting in significant mortality and morbidity

Objectives: The aim of this study is to compute the radiation attenuation parameters such as mass attenuation coefficient, linear attenuation coefficient, half value layer, mean free path, and effective atomic number for some selected chemotherapy drugs such as Lomustine, Cisplatin, Carmustine, and Chlorambucil in the energy range from 1 keV to 100 GeV. Materials and Methods: The mass attenuation coefficients were calculated with the help of WinXCOM program. Using the obtained mass attenuation coefficients, other parameters such as linear attenuation coefficient, half value layer, mean free path, and effective atomic number were derived. Results: It is observed that the variations of these parameters with respect to the photon energy show changes in different energy regions. According to the obtained results, Cisplatin has the highest mass attenuation coefficient, linear attenuation coefficient and effective atomic number results among the selected chemotherapy drugs. Moreover, Chlorambucil has the highest half value layer and mean free path results among the selected chemotherapy drugs. Conclusion: The results of this study are useful for applied science fields such as radiation physics, pharmacology, and medical physics. These results may be useful when the selected chemotherapy drugs are used together with radiology.

Background:While recognition and documentation of true drug allergy is critically important, most physicians acknowledge that its prevalence is likely overestimated, often on the basis of historical, sometimes anecdotal evidence. Correct or not, once applied, drug allergy labels may result in altered, potentially inferior therapy, increased costs and prolonged hospitalisation. Objective:Estimate the point prevalence, accuracy and symptomatology of self-reported drug allergy in a typical, large NHS Acute Trust adult inpatient population. In the subset with penicillin allergy (PA), estimate additional management costs from the use of alternative antibiotics and readmission rates in the previous 5 years. Methods:Data on self-reported drug allergies were extracted from 440 adult inpatient prescription charts over a 4 month period. Where penicillin allergy (PA) was reported, alternative antibiotic regimens were recorded and their additional costs calculated. Hospital electronic records were used to assess readmission rates of PA patients. Results:194/440 inpatients (44.5%) reported at least one drug allergy. Antibiotic allergy was most commonly reported (51%), followed by analgesic (23%) and antiemetic (12%) allergy. PA accounted for 76% of reported antibiotic allergy. The commonest reported symptoms were cutaneous (42%) and gastrointestinal (18%). Where antibiotic therapy was required for patients with PA to manage acute infections, Ciprofloxacin, Clarithromycin, Teicoplanin, Clindamycin and Cefuroxime were the most commonly employed alternatives. Extrapolation of these figures to include the entire Trust inpatient population suggested that the use of alternative antibiotics in PA patients incurred additional annual expenditure of £268,000. Further, 87% of PA patients had been admitted more than once in the preceding 5 years, with 74% requiring further courses of antibiotics during these admissions. Conclusion:Self-reported drug allergy, and in particular PA, is common in hospital inpatient populations and, in addition to the potentially unnecessary hazards to individual patients resulting from the use of alternative antibiotics, results in a considerable additional financial burden to the healthcare system. This problem could be eliminated by the provision of a nationwide and equitable tertiary Allergy service.

Exposure to environmental chemicals is a potential cause for the rapid increase in the prevalence of allergic asthma over the last few decades. The production of the environmental estrogen bisphenol A, the monomer of polycarbonate plastics, has increased rapidly over the last 50 years, such that bisphenol A is one of the most highly produced chemicals. It is detectable in the urine of the vast majority of the human population. While the relationship between the increase of bisphenol A in our environment and the prevalence of asthma does not prove a cause and effect relationship, it provides a strong rationale for experiments that have tested the hypothesis. Because of its small molecular size and hydrophobicity, bisphenol A is easily transferred from the mother to the fetus, via the placenta and in breast milk. We have reviewed all the publications available on medline on the human epidemiological studies of the early bisphenol A exposure on the development of allergic asthma and experimental studies using mouse model of the effects of early bisphenol A exposure on the development of asthma. There are eight human epidemiological studies and five mouse model studies currently published. The human studies suggest that bisphenol A exposure in early life enhances the likelihood of developing asthma on at least one of the study groups. The effects of early bisphenol A exposure were observed as an enhanced development of asthma before adolescent in the animal model.

Purpose: Percutaneous abscess drainage (PAD) is the first-line approach for abscess in Crohn’s disease (CD) since it procrastinates or avoids surgery especially in postoperative abscesses [within 30 days post-operative (p.o.)]. We retrospectively evaluated the effectiveness, complications and outcome after PAD in postoperative and spontaneous abscesses and factors influencing the outcomes. Methods: We performed PAD in 91 abscesses, 45 (49,5%) postoperative and 46 (50,5%) spontaneous. We defined the overall success (OS) as clinical (CS) and technical success (TS) when imaging documented the resolution of the abscess with no surgery within 30 days. Conversely, patients without abscess at the time of surgery, were considered as TS but clinical failure (CF). We also analyzed the overall failure (OF) defined as CF with or without technical failure (TF). Overall technical success (OTS) was OS plus TS. Complications were classified as major and minor according to the Interventional Radiology Criteria. Results: In postoperative abscesses we found 91% OS, 9% OF, no TF and 100% OTS. In spontaneous abscesses we found 33% OS, 67% OF, 6.4% TF, 95,6% OTS. A total abscess resolution was achieved in 97,8% of patients. No major complication occurred; only 1 case of minor complication. Factors statistically influencing the outcome were postoperative vs spontaneous collections (OF: 9% vs. 67%, p < 0.0001), multiloculated vs uniloculated collections (OF: 38% vs. 1%, p < 0.0001) and upper abdominal vs lower location (OF: 13% vs. 25%, p <0.05). Conclusion: Our data confirms the safety and effectiveness of PAD even in cases needing surgery within 30 days; most remarkable, PAD allows avoidance of early reoperation in almost all the patients with postoperative abscess.

The insufficiency of interferon production and the cytokine imbalance in patients with atopic dermatitis, especially in combination with persistent herpes virus infection, has been identified. The expediency of the use of interferon inducer Cycloferon in the treatment of chronic atopic dermatitis has been shown.

Inflammatory Bowel Disease (IBD)-associated arthritis is called Enteropathic Arthritis (EA) which is classified among the group of Spondyloarthritis (SpA), because its presentation is variable. The current trend is to classify them as autoinflammatory rather than autoimmune diseases, since no antibodies have yet been identified. The study of biomarkers (BM) will help us with early identification and hence, to provide treatment in the early stages, prior to radiographic progression, which will enable prompt identification of the disease phenotype. 42 patients diagnosed with IBD were included, of which 48% were females; the mean age of the study group was 48.12 ± 5.02 (95% CI). The average time of evolution of disease was 37.57 ± 14.28 months; most patients referred to the rheumatologist had a diagnosis of ulcerative colitis (83%). According to our analysis, we were able to determine that the three most significant variables influencing the development of sacroiliitis were: Lactoferrin, ANCA and HLA B27 (p < 0.5). The variable that can be ruled out because of its almost neglectable contribution was fecal calprotectin.

The widespread availability of non-traditional dietary supplements and pharmacologically active substances via the Internet continues to introduce mechanisms for inadvertent toxidromes not commonly seen. Consumers are virtually unrestricted in their ability to acquire products purporting augmentation of normal physiology for the purposes of enhancement, recreation, and/or potential abuse. The safety profiles at standard or toxic doses remain largely unknown for many agents that can be purchased electronically. We report a case of mixed toxicity related to phenibut and fosaracetam, both of which are readily available for consumer purchase from online retailers. Written and verbal consent was obtained for this case presentation.

Introduction: Forty-six per cent children have allergic rhinoconjunctivitis (Allergologica 2005). Working hypothesis: Ocular topical cyclosporine improves the quality of life for these patients. Material, methods, design: 2-year prospective study (2015-16), 40 patients with topical corticosteroids without improvement, followed 20 and 20 switched to corticosteroids cyclosporine 0.05%. Interview with Quality of Life Questionnaire in Children with rhinoconjunctivitis (PRQLQ) before and at the end of treatment. Mean age of 10.3 years with 60% male-40% female. Treatments were applied from January to March. There were 15 questions divided into two blocks. Children responded using a card with responses rated from zero (not bothered at all) to 6 (quite upset). Results: Before the 100% reported that, the itching was very bothersome. In the group of 40 children, 80% showed symptoms of epiphora and 60% showed symptoms of ocular inflammation. 100% complained of significant discomfort in rubbing their eyes, 30% did not like to take medications. Headaches affected 20%. 100% stated that they cannot play normally. 80% showed decreased concentration in class. Continuing with corticosteroids did not show statistically significant changes. Patients with cyclosporine improved the results by 3 points, with decreased itching, tearing, swelling, pain, eye rubbing, medication and headaches. In the 2nd questionnaire there was limited variation in the results related to fatigue, malaise, and irritability but with substantially improved balance of sleep, insomnia and concentration at school. Conclusion: Cyclosporine A is a cyclic polypeptide calcineurin inhibitor developed from the fungus Tolypocladium inflatum. The first dilution was 2% but it is currently used at a dilution of 0.05% and recent publications suggest nanosuspensions. Our study showed improvement in parameters related to symptoms, especially itching and lower improvement of psychological aspects, this achieves a better quality of life for children and more willingness to adhere to the treatment.

Background: Leukemia is frequently associated with fundoscopic abnormalities. However, no organized effort has been made for analyzing leukemic retinopathy in our country. This study was done to observe the demographic profile and correlation between fundoscopic findings of retinal exudates and hematological parameters in leukemic patients. Materials and Methods: The study was a hospital-based descriptive cross-sectional study among 50 leukemic patients in Medicine and Oncology departments of Bangladesh Medical College and Hospital (BMCH) from May, 2020 to October, 2020. Fundoscopic examination was done which was reviewed by an ophthalmologist. Collected data was analyzed statistically by using SPSS-17 (Chicago, Illinois). Results: Among 50 leukemic patients’, the fundal lesion was detected in 32 patients (64%), retinal exudates are rare. Only 3 patients (6%) had exudates while others (29 patients, 58%) have retinal hemorrhages. Exudates did not show any statistically significant relationship with types of leukemia (p value = 0.53). There was no statistically significant association between fundal exudates and high white cell count (p = 0.56) or low hemoglobin level (p = 0.11) or low platelet level (p = 0.11). Conclusion: This study has identified retinopathy occurring frequently in leukemic patients. Therefore, an adequate attention should be paid at fundoscopic evaluation while treating leukemic patients.
