I have read that carrageenan solution causes swelling/ oedema upon subcutaneous injection. I was wondering, could it cause swelling/ oedema upon contact with mucous membranes such as the lining of the mouth/ respiratory tract, in high concentration?

Ever since I was a kid I have the fear of getting painfully injured, like being cut by a very sharp knife. I think this type of phobia is called agliophobia. Angliophobia (the fear of pain) can be a serious problem and can even paralyze a person. Agliophobia is a psychological disorder that can be described as the fear of experiencing pain. In most cases, the person fears an event that may potentially cause pain. The fear may be worse than any real potential injury that could actually occur, making the fear illogical. http://www.wisegeek.com/what-is-agliophobia.htm

Hello, everyone! First of all, I wish to apologize for stepping into a place where only the medical minds reside. To my relief, though, I’ve noticed that similar events have already occurred on these forums – that is, cases in which a question was asked by a layperson writing a novel with plot points involving viruses or bacteria. That is what I am doing, and I greatly wish to make this plot point seem plausible. I’m not sure if it is possible to mix this particular concept with the rest of the plot to such a point where a biologist would wave it off as actually acceptable… but, hopefully, at least to the point of not having said biologist angrily throw the book acro…

what are the factors effectinf API 20E test strips which are based on phenotype? help me guysss

Hi everyone, I know it sounds obvious. But in cerbral oedema lets say due to vasgenic cause,the problem is cerebral vessels becoming more permeable and leaking out blood to extravascular compartment. Now how does the brain get bigger due to this. I mean for brain to get bigger, the intracellular fluid volume of brain cells must increase. So when these capillaries leak blood out, do near by brain cells absorb these water, increasing their intracellular volume and as a result we get enlarged brain? or does this leaked out fluid get stuck in brain interstitium making it bigger. I hope u understand my confusion, because leaking out fluid must make brain smaller otherwis…

Hello everybody . What's the rational of using such term '' incentive '' for the device ? I am not native English speaker ,however it means basically motivation induction . What kind of an incentive the patient might get ?

Hi: I've heard that most types shock of any can cause diarrhea because the autonomic nervous system responds to the hypoperfusion by constricting blood vessels that supply the colon. This starvation of oxygen irritates the colon, leading to diarrhea. However, in septic shock, all blood vessels around the body dilate due to chemicals released as a result of the infection. So how does septic shock cause diarrhea, if intestinal circulation isn't impaired? Thanks, GX

Hi, Does anyone have an idea what this is? It was deeply imbedded in my back for about two years and although it was visible from the skin surface (looked kind of like an ingrown blackhead) it needed a significant incision to be removed. It is round, hard, and 2.75mm tall by 2mm wide. Any ideas? Thanks!

For the past 2 years I have been poisoned from something in my house. It started off gradually with feelings of tiredness and muscle aches and escalated to such a degree that we actually had to leave our home. I suspect that it is a gas that is in the tap water because of several things that have occurred, though it may also be a chemical that settles into the water somehow. In addition, we had a new neighbor move in about a month ago and she immediately asked if there was something wrong with the plumbing. We've kept in contact after the move and she has developed many of the same symptoms that we have dealt with, mainly the headaches and bloody noses. We have pursue…

If there is evidence that a plant extract is good for treating Parkisons disease, how do we make this a drug? Are there other ways to make this a mainstream treatment for pd, without making it a drug? Thanks, Dmitriy

Hello, I'm simply confused how effective is giving aspirin in various cardiac disorder? Ok someone develops severe chest pain, presents to hospital within 3 hours due to MI?Is there any use in giving aspirin. I know aspirin disaggregates platelets, and this is primary haemostasis. Now within 3 hours I believe primary haemostasis is already done, so is their any point in giving aspirin. What I'm basically asking is how long does primary and secondary haemostasis take and also lets say a full thrombus was formed then is the only choice available is to lyse it with streptokinase, or does aspirin have an effect even after a full thrombus is formed. Then having said all th…

Hello everyone, You usually get pulmonary oedema in conditions such as Left heart failure, where there is increased back pressure in pulmonary vasculature, which in turn increase hydrostatic pressure and then fluid in alveoli giving rise to the condition. Now my question is this fluid in alveoli is a transduate it does not contain blood, however the classic symptom of this condition is pink frothy sputum which indicates blood. Why is this the case. Thanks

An Interesting talk from Simon Baron-Cohen as he discusses an article written by Ioan James for the Journal of the Royal Society of Medicine, which claims that scientists -- including Isaac Newton, Henry Cavendish, Marie Curie and Paul Dirac -- showed signs of autism

I've been trying to dispel the myth (in my family) that being out in the cold causes you to catch a cold. Naturally I try the simplest approach and say that a cold is caused by a virus, and unless you actually catch a virus while out in the cold weather, the actual cold itself won't make you sick. Likewise, it is believed that standing under a ceiling fan with your head wet can make you sick. Or going outside with your head wet causes pneumonia, etc. As far as I know and have read, none of this is true. The closest I've come to anything suggesting otherwise is that maybe some viruses are more prevalent during the cold months, which makes them easier to catch. But again, i…

I found out recently that Have been dating a pathalogical liar. If you do not know what this is, read carefully: it is someone who fabricates nearly everything in their lives, briliantly, almost undetectably. It is very scary and I am realizing, now, that I developed arthritis in my fingers between the 2nd and 3rd dates with this person. The though occurred to me that perhaps he drugged my food and somehow this has caused the crippling of my hands. I could see someone of thi nature carrying something like this out bc once I would find out who he"really" is (much less 'adequate' in his own eyes than the millionaire, ebonaire perosn he made himself out to be), I…

According to Dr. Stephen Devries the Mediterranean Diet reduces the risk of heart disease by 74% and reduces the risk of asthma 72% when their mother is on a Mediterranean Diet during pregnancy. See video:

By concentrating, I am able to produce a sensation throughout my body in my nervous system. Anywhere from my brain to my toes works. Given that any sensation is the passage of an electromagnetic signal, what is the physiological effect of this on my nervous system? Could it be that I am capable of "massaging" my nervous system? Or am I contrubuting to wear of my nervous tissue? Perhaps there is no effect at all?

Americans live longer base from the statistics, thus making the population age and as it ages the need for home care workers will grow significantly. According to the Bureau of Labor Standards, the Home Care Workforce will grow from 1.7 Million to 2.6 million in 2018, but the people caring for seniors in their homes earn on average less than 10 dollars an hour and many do not get benefits. A number of those workers assembled at the Food and Medicine Headquarters in Brewer Thursday to encourage their Senators to make it a priority to improve pay, benefits and training for this growing workforce. Helen Hanson stood at a podium from her huddling under the tent and shar…

Hi dear readers! To improve blinds' stick, lasers and previously acoustic sensors seem an obvious choice, to detect and range objects and obstacles sooner. http://www.lac.u-psud.fr/teletact/publications/report_training.htm (among many) Though, the varied designs have not replaced the white stick. One reason could be that the acoustic signal that represents the distance competes with useful surrounding sounds and is difficult to use to make a mental image of the surroundings. It would also have to represent very fast variations: if the user scans 5m width in 1/4s, a 0.1m pole lasts for 5ms only, which is difficult to perceive through a pitch change - such a fast sweep is…

I have an incredible fear of pain and of getting cut by something sharp, like a very sharp knife. So how can I treat my fear of being cut by a sharp knife? Is there something that can help me with it?

Dear All, A friend of mine met a road accident and an injury to his brain stem occurred.She is not able to berathe on her own since the day of accident (around 60 days)and her BP also has to be controlled from time to time.She is not responding to any external stimuli. However her digestion is working fine and doctors said she had mensus also recently. The doctors are unable to take a CT scan to check if any signals are in the brain as she is on ventilator support and they are afraid to move the patient. Her parents have tried pranic healing and alternate medicines such as homeopathy with no affect.The doctors are also surprised on how the digestion works normally but…

A new bird flu strain (H7N9) infecting humans has emerged in China. 3 infections were confirmed yesterday, 2 of whom died, in Shanghai. 4 new cases in a serious condition were confirmed today, in 4 different cities in the same province, north of Shanghai . Only 1 of the 4 had occupational contact with poultry. None of the contacts of the 7 confirmed cases have shown signs of the virus, so it looks as if (thus far) there's no human to human transmission. However, two sons of one of the fatalities have been in hospital with 'serious pneumonia', one dying. It's not confirmed they were infected, but they obviously were. However, this family were butchers, so could have been…

Hi, I'm sophomore student who wants to become a doctor. I have few ideas on colleges but I want to see more options. If you know any good medical school or accelerated program, please post here. Thanks.

Ok Guys, I'm panicking. I've been one of those "i wanna be a doctor" kids since I could walk. And I pursued that dream until...about 6 months ago. I started out as a bio major in undergrad, hated learning about plants, talked to a bunch of people and settled on an English degree. Five novels courses later I decided I couldn't stand not studying medicine and decided to continue my pre-medicine track. But I was about to turn 23, lose my parents insurance and found myself graduating with my English degree, getting a 'real' job with my own insurance and taking the required chemistry and physics courses I had yet to finish post grad. I have worked in a hospital setting sin…

Hi guys, I'm new here. Quick question, and I really need help doing so. How do I trick my mind into seeing clear, vivid things that aren't actually there? Google was useless, so this is really my last hope. There's got to be some way. Oh, and I'm sorry if this is in the wrong section, I thought it would fit under here best.
