The long-standing answer has been that sneezing is a reflex. When irritants — such as germs, dust, pollen, animal dander, or pollutants, just to name just a few — infiltrate the nose lining, the brain sends out a signal to get rid of it. That triggers a deep breath, which gets held in the lungs.

Portal hypertension is an increase in the blood pressure within a system of veins called the portal venous system. Veins coming from the stomach, intestine, spleen, and pancreas merge into the portal vein, which then branches into smaller vessels and travels through the liver.

-Korsakoff's syndrome is a common and preventable sequel of Wernicke's encephalopathy. Thiamine, if given during the stage of Wernicke's encephalopathy, can prevent the onset of Korsakoff's psychosis. The administration of glucose prior to thiamine can precipitate Korsakoff's syndrome, as seen in this case. In such patients, brain MRI frequently shows abnormal enhancement of the mammillary bodies & thallamus

Angina results from a reduction in the oxygen supply/demand ratio. Therefore, in order to alleviate the pain, it is necessary to improve this ratio. This can be done either by increasing blood flow (which increases oxygen delivery or supply), or by decreasing oxygen demand (i.e., by decreasing myocardial oxygen consumption).

Capnography, the graphic display of the exhaled and inhaled carbon dioxide concentration plotted against time, is used to monitor ventilation. This video reviews the principles of capnography and explains how to interpret the information it provides.

Lewy body dementia, also known as dementia with Lewy bodies, is the second most common type of progressive dementia after Alzheimer's disease dementia. Protein deposits, called Lewy bodies, develop in nerve cells in the brain regions involved in thinking, memory and movement (motor control). Lewy body dementia causes a progressive decline in mental abilities. People with Lewy body dementia may experience visual hallucinations, and changes in alertness and attention. Other effects include Parkinson's disease-like symptoms such as rigid muscles, slow movement and tremors.

This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve’s place. The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI). Valve-within-valve — How does it work? Somewhat similar to a stent placed in an artery, the TAVR approach delivers a fully collapsible replacement valve to the valve site through a catheter. Once the new valve is expanded, it pushes the old valve leaflets out of the way and the tissue in the replacement valve takes over the job of regulating blood flow.

Medical providers divide the spinal cord into four distinct regions. Knowing the region in which the injury is located is often the key to understanding diagnosis and treatment. The four spinal cord regions are: The cervical spinal cord: This is the topmost portion of the spinal cord, where the brain connects to the spinal cord, and the neck connects to the back. This region consists of eight vertebrae, commonly referred to as C1-C8. All spinal cord numbers are descending, so C1 is the highest vertebra, while C8 is the lowest in this region. The thoracic spinal cord: This section forms the middle of the spinal cord, containing twelve vertebrae numbered T1-T12. The lumbar spinal cord: This is a lower region of the spinal cord, where your spinal cord begins to bend. If you put your hand in your lower back, where your back bends inward, you're feeling your lumbar region. There are five lumbar vertebrae, numbered L1-L5.

The first step is to see if you have pigmentation issues -not really classed as acne scars, but this is controversial, or if you have contour changes. The best thing to do is to examine under tangential or angled lighting, as this will reveal all. Once this is done, scars can be subtyped and mapped, with high resolution photos. The second aspect, which is equally as important is to examine scars upon animanation, namely when you speak, smile and move your face. This will give me an idea of the amount of tethering and anchored acne scars. Time and time again I get request for ‘what is the treatment’ with static photos, an impossible task to answer correctly. Acne scar assessment has to be done live- with the patient in front of you, and lighting from all angles. Photos do not map scars as well a real time examination under magnification and lighting.

Like a fine whiskey barrel and wine cellar, cannabis also comes at its best when aged in a dark, cool place. Though there is no steadfast expiration date for cannabis, the method you use for preserving the cannabis makes a big difference in maintaining the buds’ freshness and potency. The question is, how do you store cannabis in a way that could extend its longevity while maintaining the vigor and freshness? Experts have described different methods. However, here are some time-proven methods that are easy and inexpensive and require very less equipment. Use air-tight glass containers to store the weed Use clean air-tight glass containers or jars to store cannabis. You can buy glass containers from any ordinary supermarket or hardware store. The tricky part is to make sure you do leave some air in the container while the air stored with cannabis isn’t in detrimental extent. Always leave 1/4 space at the top of the canister or container. Do not fill the containers to the brim with the buds. If you leave no air, then the buds will dry out. If you have too much air, the buds will get damp and moldy. Freeze your cannabis in a convenient temperature The best way to store your buds is in air-tight glass jars, in a cool and dark place under an ideal temperature between 60 and 70 degrees Fahrenheit. If you need to store a high volume of cannabis, you can freeze them after keeping them completely dry for a period of 4 weeks. On this note, you should know that you must not handle frozen buds until it becomes normal in room temperature as trichomes become brittle and can easily break off in freezing temperature. Refrigerate your cannabis (Not Recommended) Even if you use airtight jars, cannabis can grow mold in the fridge. So, you should avoid storing cannabis in the fridge. If you can’t help but doing it, make sure the weed is completely dry and put them in the back where the humidity and temperature don’t fluctuate. Plastic Baggies (Worst method!) Albeit this is very common among people who aren’t expert in handling cannabis, this is the worst of all storage methods. Cannabis gets brittle and dries out in plastic bags. It also loses its natural smell, and the potency deteriorates sharply. So, it should be avoided entirely or can be used for a short-term if there is no better alternative. Here are some things you should know while storing cannabis - Make sure cannabis has been cured for at least 4 weeks before putting them into long-term storage. Without proper curing before storage, the buds can lose their strength and smoothness. - Sunlight can stop the medicinal qualities of cannabis. Your cannabis, if stored correctly, can maintain its medicinal qualities for a few years. Exposure to Sun will turn your cannabis brown, no matter how you have stored it away. - Air-tight, nonporous glass jar are the best way for storing the buds for long term. You can use metal or plastic box/bag, but that could reduce the smell and taste after a while. - Avoid heat and middling temperature in the place where you store your buds. The ideal temperature is 60-70°F (15-21°C) or under 32°F (0°C). Extra heat, cold or middling temperature cause the cannabis potency to decrease. - Keep your cannabis away from any electronic devices or appliances that will expose the cannabis to heat. Keeping cannabis on top of a microwave, or near a laptop or mobile charge is a bad idea.
