Trans-oral resection of Nasopharyngeal Pleomorphic Adenoma : a case report

Introduction: Around 80% of all salivary gland tumours are pleomorphic adenomas, most commonly found in the parotid gland. This case report regards the rare finding of a pleomorphic adenoma in the nasopharynx. Case Presentation: a 29 year old lady presented to the ENT department with a 4 month history of worsesning and non-resolving nasal obstruction, change in voice, snoring and right aural congestion. A smooth mass pushing the uvula forward was seen on oral examination, and flexible nasoendoscopy revealed an exophytic mass from the right nasopharynx. CT and MRI showed a non-erosive mass in the right nasopharynx. Incisional biopsy was carried out which showed features of pleomorphic adenoma. Lesion was excised using transoral technique to remove the tumour with an intact capsule. Literature Review and Discussion: A PubMed search found only 12 previously reported cases of pleomorphic adenoma from 1970 to 2015. The treatment of choice was surgical in all cases, one case reports the use of radiotherapy, without affect. The trans-oral technique used in this case ensured that the tumour was removed with the surrounding capsule intact, thus reducing risk of recurrence. Conclusion: This is the first reported case of nasopharyngeal pleomorphic adenoma from Malta. Diagnosis was made by the triple assessment – examination, radiology and histology. The tumour was excised completely and the plan is for the patient to have regular follow up.peer-reviewe

Ritual During Covid-19

The following teaching module is designed for high school and college level instructors who seek to teach a lesson on the impact the COVID-19 pandemic had on the participation and practice of religious rituals. The teaching module features a lesson plan, case studies, and assignments that can be incorporated as the instructor sees fit. This teaching module was created by Western Michigan University\u27s Department of Comparative Religion

Prevalence of meticillin-resistant Staphylococcus aureus colonisation amongst residents in Maltese nursing homes

Since the 1960’s, meticillin-resistant Staphylococcus aureus (MRSA) has become a major pathogen with everincreasing incidence rates of hospital-acquired and community-acquired infections. Malta has currently one of the highest rates of hospital-acquired and community-acquired infections in Europe. In addition, reports have estimated community carriage at more than 8%. MRSA carriage in homes for the elderly is very important because these residents are often hospitalized and therefore serve as a source of transmission. The aims of this study were to establish the prevalence of MRSA nasal carriage amongst residents in nursing homes in Malta, to determine their antibiotic susceptibility and to determine the significance of specific risk factors found in the literature. Nasal swabs were taken from 397 randomly chosen residents in 10 governmental nursing homes. A short questionnaire including possible risk factors reported to be associated with MRSA nasal carriage was also filled. MRSA carriage amongst nursing home residents was 19.4% (95% CI 17.6 – 21.2%) ranging from 0% to 25% amongst the nursing homes studied. Logistic regression analyses indicated that previous hospital admission was the only risk factor that was found to be significantly (OR: 1.956, p: 0.011; 95CI 1.163 - 3.290) associated with MRSA nasal colonization amongst nursing home residents.peer-reviewe

Solvent-free, one-pot, multicomponent synthesis of xanthene derivatives

An efficient and environmentally benign one-pot condensation of cyclic diketones, aldehydes and naphthols was achieved with 1,4-diazabicyclo[2-2-2]octane supported on Amberlyst-15 as a novel catalyst, producing a variety of benzoxanthenones in good to excellent yields. The advantages of this multicomponent reaction include the use of a heterogeneous catalyst, solventless conditions and a simple methodology that is atom-economical and results in low E-factor values. A total of 17 xanthene derivatives, including two novel molecules, were synthesized and then characterized. Aromatic aldehydes carrying an electron-withdrawing group provided excellent yields. Appreciable results were also obtained using aliphatic aldehydes. The catalyst is fully recyclable and can be reused up to six times.peer-reviewe

Prevalence of obesity in Malta

Background: Obesity is a global epidemic with the Mediterranean island of Malta being no exception. The World Health Organization (WHO) has identified Malta as one of the European countries with the highest obesity prevalence. Method: A cross-sectional study was conducted (2014–2016) under the auspices of the University of Malta. The prevalence of overweight-obesity in Malta was calculated and then age stratified for comparisons with previous studies. Results: The study identified 69.75% (95% CI: 68.32–71.18) of the Maltese population to be either overweight or obese. The men overweight/obese prevalence (76.28% 95% CI: 74.41–78.14) was statistically higher than that for women (63.06% 95% CI: 60.92–65.20) (p = 0.0001). Age stratification revealed that both genders had the highest overweight prevalence rates between 55 and 64 years (Men = 23.25% 95% CI: 20.43–26.33; Women = 24.68% 95% CI: 21.44–28.22). Men obesity prevalence rates were highest in the 35 to 44 years group (22.52% 95% CI: 19.65–25.68) while for women it was highest in the 55 to 64 years group (28.90%, 95% CI: 25.44–30.63). Conclusion: Over a 35-year period, an overall decrease in the normal and overweight BMI categories occurred with an increase in the prevalence of obesity. An exception was observed in the women, where the prevalence of normal BMI increased over this time period. Also, it appears that while the total population obesity prevalence increased (for 2016), a percentage of the women have shifted from an obese to an overweight status.peer-reviewe

Dust in Comet C/2007 N3 (Lulin)

We report optical imaging, optical and near-infrared polarimetry, and Spitzer mid-infrared spectroscopy of comet C/2007 N3 (Lulin). Polarimetric observations were obtained in R (0.676 micron) at phase angles from 0.44 degrees to 21 degrees with simultaneous observations in H (1.65 micron) at 4.0 degrees, exploring the negative branch in polarization. Comet C/2007 N3 (Lulin) shows typical negative polarization in the optical as well as a similar negative branch near-infrared wavelengths. The 10 micron silicate feature is only weakly in emission and according to our thermal models, is consistent with emission from a mixture of silicate and carbon material. We argue that large, low-porosity (akin to Ballistic Particle Cluster Aggregates) rather absorbing aggregate dust particles best explain both the polarimetric and the mid-infrared spectral energy distribution.Comment: 18 pages, 9 figures, 3 table

Effect of a 12-week online walking intervention on health and quality of life in cancer survivors: a quasi-randomized controlled trial

Cancer survivors are at an increased risk of experiencing physical and psychological ill-effects following cancer treatment. Rural cancer survivors are at a greater risk of future health problems following a cancer diagnosis compared to their urban counterparts. Physical activity has been targeted as a health promotion priority in cancer survivors. Research indicates that a large portion of cancer survivors do not meet physical activity recommendations. The purpose of this quasi-randomized controlled trial was to test the effectiveness of an online 12-week walking intervention designed for cancer survivors, and to explore its impact on physical health indicators and quality of life outcomes. Steps Toward Improving Diet and Exercise among cancer survivors (STRIDE) is an online resource designed according to Social Cognitive Theory and Self Determination Theory, based on individualized step goal setting. Measures of physiology, physical fitness, and quality of life were taken at the baseline, post-intervention, and three-month follow-up in an Intervention group (n = 46) and active Control group (n = 45). The Control group was provided with a pedometer but did not have access to the online program. Three-factor repeated measures ANOVAs indicated that there were improvements in physical fitness (p < 0.01), systolic blood pressure (p < 0.01), diastolic blood pressure (p < 0.01), waist girth (p < 0.01), mental health (p < 0.05), social functioning (p < 0.01), and general health (p < 0.01), but an increase in bodily pain (p < 0.01), from the baseline to week 12 and the three-month follow-up, irrespective of group allocation. Pedometer interventions, delivered with or without online support and step goal setting, show promise for improving the overall health of cancer survivors, at least in the short term.Lauren J.
