Helpful hints for contact lens laboratory

Currently there is a large number of types of contact lenses. In addition to the now classic rigid (PMMA) lenses and hydrogel lenses, the emergence of rigid gas-permeable lenses has expanded the fitting options for practitioners. The :patient must be fitted with the appropriate lens. The question of which lens to choose IS perhaps the fitters most important decision. Does one go for the short-term reward and choose a soft lens, because it meets with early and rapid patient acceptance or does one consider a rigid gas-permeable lens, which may be superior in the long term with the advantage of Improved vision, durability and easier care? This manual is designed to help the novice fitter answer this question and lessen the apprehension, frustration and confusion of fitting contact lenses

Novel M4 Pediatrics Chief Program Utilizing Near-peer Teaching and Mentoring to Enhance Clerkship Curricula

Introduction: Near-peer teachers add many benefits to the academic, clinical performance, and enjoyment of near-peer learners in medical education. This enterprise describes and examines how the Creighton University School of Medicine M4 Pediatrics Chief Program fills a gap in medical education by offering an organized and formal methodology for near-peer teaching. The Creighton University M4 Pediatrics Chief Program utilizes select fourth year medical students to orient, teach basic clinical skills, mentor, and participate in curriculum development for the third year Pediatric clerkship students. Methods: Third year students (n=43) in their Pediatrics clerkship from September 2020 to February 2021 completed surveys at the end of the clerkship to assess the quality and effectiveness of the M4 Pediatrics Chief Program. Results: Students rated effectiveness of the Chiefs most highly as clerkship guides (4.29, SD=0.79), teachers (4.21, SD=0.92), and mentors (4.19, SD=0.75). Near-peer perspectives, education, provision of pertinent content, serving as a clerkship resource, and being a source of encouragement were the most beneficial aspects of the program. Students reported strong agreement all clerkships should have an M4 Chief Program (4.53, SD=0.88). Discussion: Because of the positive reviews by the third years students, the M4 Pediatrics Chief Program is now a permanent part of the Pediatric Clerkship. Additionally, other third year clerkships at Creighton University School of Medicine are adopting this model. Finally, the M4 students acting as the chiefs gain valuable leadership and educational skills. Conclusion: Based on positive perceptions of the “M4 Chief Program”, the authors recommend other medical schools consider initiating similar programs within their third year clerkships.https://digitalcommons.unmc.edu/chri_forum/1037/thumbnail.jp

Screening history of women with cervical cancer: a 6-year study in Aarhus, Denmark

To identify possible weaknesses in cervical screening in Aarhus County, 10 years after the programme was introduced, screening histories were examined. A major problem for the screening programme was that 31% of women were never screened and 61% under-screened, the latter group being significantly dominated by older women and high-stage tumours

Skin flora: Differences Between People Affected by Albinism and Those with Normally Pigmented Skin in Northern Tanzania - Cross Sectional Study.

Skin flora varies from one site of the body to another. Individual's health, age and gender determine the type and the density of skin flora. A 1  cm² of the skin on the sternum was rubbed with sterile cotton swab socked in 0.9% normal saline and plated on blood agar. This was cultured at 35 °C. The bacteria were identified by culturing on MacConkey agar, coagulase test, catalase test and gram staining. Swabs were obtained from 66 individuals affected by albinism and 31 individuals with normal skin pigmentation. Those with normal skin were either relatives or staying with the individuals affected by albinism who were recruited for the study. The mean age of the 97 recruited individuals was 30.6 (SD ± 14.9) years. The mean of the colony forming units was 1580.5 per cm2. Those affected by albinism had a significantly higher mean colony forming units (1680  CFU per cm²) as compared with 453.5  CFU per cm² in those with normally pigmented skin (p = 0.023). The skin type and the severity of sun- damaged skin was significantly associated with a higher number of colony forming units (p = 0.038). Individuals affected by albinism have a higher number of colony forming units which is associated with sun- damaged skin

Architectures of control in consumer product design

Copyright @ 2005 Social Services Research GroupThe idea of architectures of control is introduced through examples ranging from urban planning to digital rights management, and the intentions behind their use in consumer products are examined, with reference to case studies of printer cartridges and proposed 'optimum lifetime products.' The reactions of the technical community and consumers themselves are also explored, along with some wider implications for society

Diversity of the Human Skin Microbiome Early in Life

Within days after birth, rapid surface colonization of infant skin coincides with significant functional changes. Gradual maturation of skin function, structure, and composition continues throughout the first years of life. Recent reports have revealed topographical and temporal variations in the adult skin microbiome. Here we address the question of how the human skin microbiome develops early in life. We show that the composition of cutaneous microbial communities evolves over the first year of life, showing increasing diversity with age. Although early colonization is dominated by Staphylococci, their significant decline contributes to increased population evenness by the end of the first year. Similar to what has been shown in adults, the composition of infant skin microflora appears to be site specific. In contrast to adults, we find that Firmicutes predominate on infant skin. Timely and proper establishment of healthy skin microbiome during this early period might have a pivotal role in denying access to potentially infectious microbes and could affect microbiome composition and stability extending into adulthood. Bacterial communities contribute to the establishment of cutaneous homeostasis and modulate inflammatory responses. Early microbial colonization is therefore expected to critically affect the development of the skin immune function
