The bladder is a hollow organ in the lower abdomen (pelvis). It collects and stores urine produced by the kidneys. The bladder is connected to the kidneys by a tube from each kidney called a ureter. When the bladder reaches its capacity of urine, the bladder wall contracts, although adults have voluntary control over the timing of this contraction. At the same time, a urinary control muscle (sphincter) in the urethra relaxes. The urine is then expelled from the bladder. The urine flows through a narrow tube called the urethra and leaves the body. This process is called urination, or micturition.
There are several approaches to scoliosis surgery, but all use modern instrumentation systems in which hooks and screws are applied to the spine to anchor long rods. The rods are then used to reduce and hold the spine while bone that is added fuses together with existing bone.
Knee osteotomy is commonly used to realign your knee structure if you have arthritic damage on only one side of your knee. The goal is to shift your body weight off the damaged area to the other side of your knee, where the cartilage is still healthy. When surgeons remove a wedge of your shinbone from underneath the healthy side of your knee, the shinbone and thighbone can bend away from the damaged cartilage. Imagine the hinges on a door. When the door is shut, the hinges are flush against the wall. As the door swings open, one side of the door remains pressed against the wall as space opens up on the other side. Removing just a small wedge of bone can "swing" your knee open, pressing the healthy tissue together as space opens up between the thighbone and shinbone on the damaged side so that the arthritic surfaces do not rub against each other. Osteotomy is also used as an alternative treatment to total knee replacement in younger and active patients. Because prosthetic knees may wear out over time, an osteotomy procedure can enable younger, active osteoarthritis patients to continue using the healthy portion of their knee. The procedure can delay the need for a total knee replacement for up to ten years.
Masturbating is totally healthy, and totally normal. There are tons of myths out there meant to scare you into thinking masturbation is wrong or bad. But the truth is masturbation is perfectly safe. Masturbating won't make you blind, crazy, or stupid. It won’t damage your genitals, cause pimples, or stunt your growth. It doesn’t use up all your orgasms or ruin other kinds of sex. In fact, masturbation can actually be good for you. Here are some benefits of masturbation: Masturbation is safer than any other type of sex. You can’t get pregnant or get any sexually transmitted infections from masturbating. Masturbation can help you learn what you like and don’t like sexually. And if you decide to have sex with someone, you can know what you do/don’t want to do. BONUS: getting comfortable talking about sex and your body with your partner makes it easier to talk about protecting yourself against STDs and pregnancy, too. Exploring your body and learning how to give yourself sexual pleasure can be empowering and help improve your body image. Masturbation can lower stress and help you relax. It even helps some people fall asleep. Having an orgasm releases endorphins — feel good chemicals in your brain. Orgasms can be a natural painkiller and can even help with period cramps. Mutual masturbation (masturbating with a partner) is a really safe way to have sex and let the other person know what feels good to you. If you share a sex toy, use condoms on the toy and clean it before swapping. And if you touch each other’s genitals, wash your hands before touching your own. Can I get an STD from masturbating? Nope. Masturbating is the safest sexual activity out there. There is virtually NO chance of getting an STD or any other infection from touching your own genitals (and there’s also no chance of pregnancy). STDs have to be passed from one person to another, so you can’t give yourself an STD. The one exception to this is herpes - so if you have any cold sores on your mouth and touch them, make sure to wash your hands before masturbating. But it IS possible to get an STD if you’re masturbating with another person and touching each other’s genitals. Anytime semen (cum) or vaginal fluids are spread to someone else’s body, or your genitals rub against each other, there’s a risk of STDs. So if you touch each other’s genitals, wash your hands before touching your own. STDs can also be spread by sharing sex toys with another person. You can help protect yourself by using condoms on any toys that you share (even if they’re not shaped like a penis). Put a new condom on anytime a different person uses it. If you’re the only one using your sex toys, you don’t have to worry about STDs. But if you use them with other people, protect those sex toys just like you’d protect your own genitals — put a condom on ‘em! It’s possible for masturbation to cause irritation or infections if your body is sensitive to the way you masturbate or the things you masturbate with — but this isn’t the same thing as an STD. Lotions, Vaseline, oils, and scented or flavored stuff may irritate your vulva and vagina. Masturbating roughly and not using lubrication can also lead to irritation because of friction. And germs from the anus can cause vaginal infections — so never put something in your vagina that’s been in your butt without washing it or covering it with a condom. If you’re worried that you have an STD because of pain, itching, or discomfort in your genitals, go to your doctor or your local Planned Parenthood health center.
For blunt trauma patients lying supine, drains should be placed anteriorly in the chest. This pevents a tension pneumothorax developing if the chest tube is blocked by dependent lung tissue. Normal movement of the lungs will allow drainage of a basal haemothorax through an anterior chest tube
A little venom is drawn into a syringe. ... The quick coagulation or blood clotting caused by the Russell's viper venom is of particular interest to scientists — there's a lot of research into how it might be used in medicine. But this effect is only present in healthy blood.
When foreign organisms such as bacteria enter the body, the immune system sends white blood cells to fight the infection. This causes swelling (inflammation) at the site of infection and the death of nearby tissue, creating a hole called a cavity, which fills with pus to form an abscess.

t’s the brain, after all, that devises experiments and interprets their results. How the brain perceives, how it makes decisions and judgments, and how those judgments can go awry are at least as important to science as knowing the intricacies of nonbiotic experimental machinery. And as any brain scientist will tell you, there’s still a long way to go before understanding the brain will get crossed off science’s to-do list. But there has been progress. A recent special issue of the journal Neuron offers a convenient set of “perspective” papers exploring the current state of understanding of the brain’s inner workings. Those papers show that a lot is known. But at the same time they emphasize that there’s a lot we don’t know.
You may have a lot of questions about epilepsy. We will help you understand the basics, answer the most common questions, and help you find resources and other information you may need.

If you have multiple sclerosis (MS), you probably had several tests done before you received your diagnosis. There isn’t one test to diagnosis MS, so testing can vary. Doctors can use neurological exams, information about previous symptoms, blood tests, and spinal fluid tests. A magnetic resonance imaging (MRI) scan isn’t used to diagnose MS but rather to rule out other diseases. A diagnosis of MS requires more information than what a scan alone can give. By looking at more than one test or exam result, doctors can get a clearer picture of what’s going on in your body.
Clinical Review First aid and treatment of minor burns BMJ 2004; 328 doi: https://doi.org/10.1136/bmj.328.7454.1487 (Published 17 June 2004) Cite this as: BMJ 2004;328:1487 Article Related content Metrics Responses Jackie Hudspith, clinical nurse lead, Sukh Rayatt, specialist registrar, plastic and reconstructive surgery Author affiliations Introduction Some 250 000 burns occur annually in the United Kingdom. About 90% of these are minor and can be safely managed in primary care. Most of these will heal regardless of treatment, but the initial care can have a considerable influence on the cosmetic outcome. All burns should be assessed by taking an adequate history and examination.
Four-Step Guide to ABG Analysis Is the pH normal, acidotic or alkalotic? Are the pCO2 or HCO3 abnormal? Which one appears to influence the pH? If both the pCO2 and HCO3 are abnormal, the one which deviates most from the norm is most likely causing an abnormal pH. Check the pO2. Is the patient hypoxic?
