Functional activities limited by people with age-related macular degeneration Introduction Activities of daily living (ADL) refer to self-care tasks. It is classified into basic ADL (BADL) and Instrumental ADL (IADL). The former one is essential for the patients in life such as eating and personal hygiene while the latter one is for the people to function in the community such as shopping. This may sound easy for a normal human being. However, for a low vision patient, even a very simple task will

Psychology What word spells J-O-K-E? Now, what do you call a white part of an egg? This is what you call, a perceptual set, our tendency to interpret things in certain ways is based on our previous experiences. This idea is part of a larger concept of study called psychology, “the scientific study of the human mind and its functions, especially those affecting behavior in a given context” (Angell). I’ve done extensive research on this topic, as well as taken a few psychology classes in the past.
Toxoplasmosis is an infection caused by the obligate intracellular parasite known as Toxoplasma gondii.1 It is estimated to be the leading cause of food-related deaths in the United States and it infects up to a third of the worldwide population. Incidence is highest in areas that are hot, humid and at a low elevation, all of which are characteristic of the southwestern US where the case patient, S.C., is from. 2,3 Cats are the common culprit as they become definitive hosts of the parasite after
Chief Complaint Migraine headaches. History Patient is a 19-year-old right-handed white male who presents with his mother for evaluation of frequent headaches. He did not have headaches prior to two grade 1 concussions while playing football in 2012. At that time, he had a normal MRI. He has been having headaches since. He did see Kent Logan, MD in 2012, at which point he was describing weekly headaches with photophobia, phonophobia, and nausea. At that time, according to Dr. Logan's notes
shows a trend of progress made through collaboration, and failure to adhere to that trend can be extremely detrimental to a field. For instance, the case of the dispute between Hermann von Hemholtz and Ewald Hering discussed in Oliver Sacks ' essay, “Scotoma: Forgetting and Neglect in Science,” is shown to be highly restrictive to the evolution of the scientific
Within the cases detailed in Jennifer Kahn 's essay, “Notes from a Parallel Universe,” and Oliver Sacks ' essay, “Scotoma: Forgetting and Neglect in Science,” there are many similarities, largely in the reasoning behind the initial failures of newly presented and highly controversial theories. Standing chief amongst them is the credibility and scientific standing of the theory 's author. Take, for instance, the case of John Frederick Herschel. Herschel, an outsider of the realm of physicians to
The chief premise of Siddhartha Mukherjee’s paper “Fighting Chance,” is rather agreeable. That is, the argument for the essential nature of basic—or curiosity driven science—stands by itself to be one that is supported by sound evidence. However, the evidence and anecdotes that Mukherjee uses are far more controversial. For instance, there is significant issue to be derived from the support for Mukherjee’s argument that the John Collier anthrax anecdote provides. Prominent amongst these issues is
INTRODUCTION Multiple sclerosis is a chronic inflammatory autoimmune disease of the central nervous system, directed against the myelin sheath. Leading to demyelination and axonal loss. It’s characterized by spread “plaques” of demielinization typically found in typically found on MRI in the periventricular region, corpus callosum, centrum semiovale and, to a lesser extent, deep white – structures and basal ganglia.(Olek, 2005) The clinical picture of the disease is rich and variated. Usually it
Introduction: Gas in 1968 described Acute Posterior Multifocal Placoid Pigment Epitheliopathy (APMPPE) as being a condition that caused acute and rapid loss of central vision due to multiple pale lesions at the level of Retinal pigment epithelium (RPE) in the posterior pole. (1) It is a self-limiting condition which recovers spontaneously over a three weeks period leaving residual pigment epithelial alterations.(2) The typical features in acute phase include cream colored placoid lesions at the
