![]() Also, note the bump above the RPE line of the neurosensory detachment of retinal layers above RPE. Here we see multiple cystic spaces in the intraretinal architecture (Sub-Segment 3). Here is an OCT image of a 61-year-old gentleman who underwent cataract surgery 3 weeks back. This fundus picture is grossly showing pigmentary changes with yellow coloured deposits over temporal part of macula along with straitening of retinal vessels around it suggesting a possible clinical condition of macular telangiectasia type 2 (MACTEL). The rest of the OCT image including the deeper layers of the retina is appearing normal.īefore commenting on the diagnosis it is wise to retrospectively analyze the fundus photo of this eye. This OCT image shows hyporeflective cavitatory spaces in the inner retina (sub-segment number 2). In this image, you can see a hyperreflective membrane in VR interface Sub-Segment which is exerting traction to the underneath retinal layers suggesting an Epiretinal membrane (ERM). Let’s learn to read one more similar OCT image. there are some other subtle abnormalities in this OCT image of VMT like cystic changes in the inner retina and the neurosensory detachment in deeper layers which we will discuss once we go through each of the 5 sub-segments). VR interface gives us a clue to the possible clinical diagnosis of vitreo-macular traction (VMT). Here we can easily appreciate a hyper-reflective layer in the sub-segment number 1 which is attached at fovea viz. Now let's see some examples of abnormal macular OCTs of common retinal diseases and interpret them by sub-segmenting them. Always correlate your OCT interpretation or for that matter any diagnostic imaging to your clinical examination findings. examine the patients in detail, try interpreting the clinical fundus photos before you jump in to read and interpret the OCT scans. My personal advice would be to be a good clinician first i. ![]() Henceforth in order to read and interpret a macular OCT scan rapidly, we must keep in mind the normal appearance of these 5 sub-segments.Ī thumb rule before interpreting any OCT image is to be aware of the background clinical history and fundus photo of the same eye of which you are going to interpret the OCT image. THIS IS HOW THE NORMAL MACULAR SCAN LOOKS LIKE. Let us first review the normal macular OCT. These5 OCT sub-segments can be used for quick interpretation of macular OCT scans. And also just by looking at the diseased/damaged retinal layer, we can identify probable clinical disease. So if we segment the OCT image into 5 layer-wise sub-segments, it becomes very easy to read and interpret the retinal pathology. How to quickly read a macular OCT?Īn OCT image gives you layer by layer information of retinal tissue. And so correct interpretation of OCT scans helps us in understanding the disease pathologically which in turn aids in prognosticating and making treatment decisions. In today’s practice, OCT is indisputably an essential diagnostic tool for every retinal surgeon. Optical Coherence Tomography (OCT) is a quick, non-invasive, reproducible, and optical analog of ultrasound imaging which is as good as in vivo viewing of individual retinal layers histologically.

![]() Foam beds maintain their original shape, whether in a vertical or horizontal position. Memory foam and latex mattresses do best when paired with a Murphy bed. While there are low-cost foam mattresses available for Murphy beds and wall beds, be aware that these brands may have policies prohibiting them from covering wear and tear associated with this bed configuration. Since wall beds place the mattress in an unusual position for many hours of the day, many manufacturers don’t recommend or allow their mattresses to be used for this purpose, and doing so voids the manufacturer’s warranty. Take note that a lot of brands have warranty policies that prohibit the use of standard solid foundations. Both hold their shape well when standing on end and provide very different sleeping experiences, so you should be able to select a mattress that suits your needs in one of these two categories. Thus, latex or memory foam mattresses are ideal for use with your Murphy bed. ![]() Innerspring and hybrid mattresses with coils are generally not advised as they are not designed to be stored vertically, which results in misshapen coils. It is critical to select the appropriate mattress for a Murphy bed. What Type of Mattre ss is Best for a Murphy Bed? There are Murphy beds with tables or desks that fold down when the bed is folded up and models with sofas, TVs, cabinets, and shelving. Since the first model, there have been numerous variations and designs, including sideways-mounted Murphy beds, Murphy bunk beds, and solutions with additional functions. When the unit is folded upright, the mattress is attached to the bed frame, usually with elastic straps to keep the mattress in place. Instead, the mattress is usually supported by a platform or mesh that keeps it from sagging when closed. The majority of Murphy beds do not come with box springs. Many of them have drop-down desks, exposed cabinets, or shelves when the bed is folded up. While you can sleep on a Murphy bed daily, one of the most common uses is in spare bedrooms for guests who don’t want to take up too much space with a permanent bed. As a result, you can use that area for whatever else you require, such as a home office or crafts’ space. Unlike your usual bed design, which takes a lot of square feet, Murphy beds use a significant amount of floor space only when in use and can be neatly stored vertically to free up space. Murphy Bed For The HomeĪpart from the picture reels, Murphy beds are useful for anyone who doesn’t have a lot of living space in their home. Read more on space-saving bed design ideas here. The Murphy Bed is also called a pull-down bed or fold-down bed. That’s why it’s usually known as a wall bed.Ī Murphy bed’s space-saving feature often makes it a popular choice for guest rooms, studio-type lofts, mobile homes, and other occupancy with limited space.

Longer-term follow-up and continued accrual in the phase 3 trial will be required to validate these findings. The University of Kansas Health System is our regions 1st provider to offer an innovative, noninvasive treatment for essential tremor or Parkinsons. Staged bilateral magnetic resonance-guided focused ultrasound thalamotomy can be performed with a reasonable safety profile similar to that seen with unilateral thalamotomy and improves the tremor and quality of life of patients with essential tremor. Seven experienced mild adverse effects, including 2 with transient gait impairment and a fall, 1 with dysarthria and dysphagia, and 1 with mild dysphagia persisting at 3 months. Tremor significantly improved in all patients. The study met both primary outcomes, with the intervention resulting in clinically significant improvement in quality of life at 3 months (mean Quality of Life in Essential Tremor score difference, 19.7 95%CI, 8.0-31.4 P = 0.004) and all patients reporting that they would elect to receive the second-side treatment again. Secondary outcomes included tremor, gait, speech, and adverse effects. The primary outcome was the change in quality of life relative to baseline, as well as the answer to the question "Given what you know now, would you treat the second side again?". We conducted a prospective, single-arm, single-blinded phase 2 trial of second-side magnetic resonance-guided focused ultrasound thalamotomy in patients with essential tremor. The objective of the current study was to determine whether bilateral thalamotomies can be performed with an acceptable safety profile where benefits outweigh adverse effects. However, this procedure does not address ipsilateral symptoms. In patients with medically refractory essential tremor, unilateral magnetic resonance-guided focused ultrasound thalamotomy can improve contralateral tremor. 8 Krembil Brain Institute, Toronto, Ontario, Canada.Division of Neurology, University of Toronto, Toronto, Ontario, Canada. Essential tremor and Parkinson’s disease cause the thalamic circuitry to become abnormal, which results in tremors. The thalamus in the brain is a relay station of motor and sensory signals.

Limit your alcohol and caffeine consumption.Reach and maintain a body weight that is healthy for you.Start and maintain a pattern of consistent physical activity.Follow an eating plan low in salt, cholesterol, saturated fat, and trans fats.If you have either condition, you should take the following steps: The American Heart Association recommends the same plan of care for AFib and AFL. Treatment Guidelines for Atrial Flutter and AFib Moreover, AFL carries a lower risk of clot formation than AFib because of the presence of flutter waves. Wolf Parkinson White Syndrome (another type of abnormality in the heart’s electrical conduction system)īoth AFib and AFL place you at risk for stroke because of the potential for the development of blood clots arising from incomplete emptying of blood from the atria into the ventricles.Moreover, AFL patients have an elevated risk of AFib occurring in the future.Īccording to physicians, the risk factors for AFib and AFL are identical and include the following: AFL also has a higher probability of reverting to a normal rhythm. If you have AFib, you can experience periods of AFL that start and stop without warning, and if you have AFL, it can flip into AFib. In both conditions, people can experience mild symptoms or none. These P waves, called flutter waves, look like the teeth on a saw, with many failing to reach the ventricles because of the speed at which they occur.ĪFib and AFL have almost the same symptoms, such as:Ītrial flutter symptoms tend to be less severe than those associated with AFib. In AFL, the P waves are visible, but there are two to four of these for every QRS wave instead of the 1:1 ratio seen on an ECG representing a normal heart rhythm.In AF, the P wave is invisible, and the QRS waves appear at frequent, irregular intervals, which produces the standard fast and chaotic heart rate.The tall, slender peak after the P wave, called the QRS wave, represents a contraction of the ventricles.ĪFib and AFL appear very different when viewed on an electrocardiogram (ECG). On an electrocardiogram (ECG), the small hump-shaped spike, called the P wave, represents a contraction of the atria. ![]() Individuals with AFL have a fast but regular pulse, while people with AFib have both a rapid and irregular pulse. Furthermore, the atria fire so fast (240 – 360 beats per minute) that only every 2 nd to 4 th impulse reaches the ventricles, producing contractions at a rate of roughly 150 beats per minute. In AFL, the sources generating electrical signals are fewer, allowing the atria to contract instead of vibrating. The reduced volume of blood transported to the ventricles further decreases the amount the heart pumps to the rest of the body by around 10 percent, posing a significant problem during physical exertion. The random signals received from the atria then cause the ventricles to contract in an irregular pattern that ranges from 100 to 275 beats per minute. Instead of contracting after accepting the incoming signal, the atria vibrate (fibrillate), which produces insufficient blood flow into the ventricles. In AFib, the electrical signals originate from many regions near the atria, with only a few of these random impulses transmitted to the atria. Heart rates in AFib are unlike those seen in AFL because of a difference in the heart’s electrical activity. AFib usually starts in the left atrium whereas AFL begins in the right atrium.īoth conditions share similar symptoms, although atrial flutter symptoms tend to be milder. The primary difference between atrial flutter and atrial fibrillation relate to variations in heart rate seen when looking at an electrocardiogram reading. AFL happens less often, and 33 percent of people who suffer from it will also experience AFib.īoth arrhythmias have the potential to cause severe problems, and a physician should address each one as soon as you notice either occurring. Also, both AFib and AFL can occur when there is no evidence of a heart problem.ĪFib is the more common of the two conditions, occurring in less than one percent of adults. These conditions are often the result of issues that cause the enlargement of the atria. Atrial tachycardias are conditions that trigger the two upper chambers of the heart called the atria to contract at speeds higher than 100 beats per minute. Atrial Fibrillation: Understanding the Similarities and DifferencesĪtrial fibrillation (AFib) and atrial flutter (AFL) are the two most frequent types of heart arrhythmias known as atrial tachycardias. 1 online beauty marketplace cosmetics club, makeup, skincare, hair care and fragrances online retailer.Įstablished in 2008 The Beauty Club has grown to become Australia's leading online beauty, skincare, make up & perfume marketplace with over 70,000 products online, Join The Beauty Club today.īeauty News / Beauty Trends: Cheap By Terry Skincare | Patchology Skincare | After Sun Care | Easy Blowout Tutorial | Party Prep Tips | Anti Aging Retinols | It's Suncare Season: spring into new SPF | The Ordinary Back in Stock-up Retailer Skincare | Foreo Beauty Devices | Hylamide Skincare | COSRX Acne Patches | QRxLABS New Skincare Brand | Dr. #1 Beauty Marketplace & Discount Cosmetics Club: The Beauty Club is Australia's No. Shop for change with The Beauty Club x i=Change!īuy Now, Pay Later with Klarna, Afterpay, ZipPay, Humm or Laybuy Kevyn Aucoin The Sculpting Powder is a contour that retails for 44.00 and contains 0.11 oz.
