Approximately 10%-15% of human bite wounds become infected owing to multiple factors. The bacterial inoculum of human bite wounds contains as many as 100 million organisms per milliliter and is made up of as many as 190 different species. Many of these are anaerobes that flourish in the low redox environment of tartar that lies between human teeth or in areas of gingivitis. Most injuries due to human bites involve the hands. Hand wounds, regardless of the etiology, have a higher rate of infection than do those in other a locations. (See Pathophysiology and Etiology.) Infections associated with human bites are often far advanced by the time they receive appropriate care. Patients often wait until infection is well established before seeking medical treatment. These wounds are frequently more extensive than estimated on initial examination by the inexperienced observer and are frequently managed inadequately. (See Prognosis, Presentation, Treatment, and Medication.) Human bites have been shown to transmit hepatitis B, hepatitis C, herpes simplex virus (HSV), syphilis, tuberculosis, actinomycosis, and tetanus. Evidence suggests that it is biologically possible, but quite unlikely, to transmit human immunodeficiency virus (HIV) through human bites. (See Pathophysiology, Presentation, and Workup.)
Hirsutism is stiff and pigmented body hair, appearing on the body where women don't commonly have hair — primarily the face, chest and back. When excessively high androgen levels cause hirsutism, other signs may develop over time, a process called virilization. Signs of virilization may include: Deepening voice Balding Acne Decrease in breast size Enlargement of the clitoris
A cornea transplant, also called keratoplasty, is a surgical procedure to replace part of your cornea with corneal tissue from a donor. Your cornea is the transparent, dome-shaped surface of your eye that accounts for a large part of your eye's focusing power. A cornea transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. Most cornea transplant procedures are successful. But cornea transplant carries a small risk of complications, such as rejection of the donor cornea.
Aortic valve replacement is a procedure in which a patient's failing aortic valve is replaced with an artificial heart valve. The aortic valve can be affected by a range of diseases; the valve can either become leaky (aortic insufficiency / regurgitation) or partially blocked (aortic stenosis).
Prostatitis is an infection or inflammation of the prostate gland that presents as several syndromes with varying clinical features. The term prostatitis is defined as microscopic inflammation of the tissue of the prostate gland and is a diagnosis that spans a broad range of clinical conditions. The National Institutes of Health (NIH) has recognized and defined a classification system for prostatitis in 1999.[1] The 4 syndromes of prostatitis are as follows: I - Acute bacterial prostatitis II - Chronic bacterial prostatitis III - Chronic prostatitis and chronic pelvic pain syndrome (CPPS; further classified as inflammatory or noninflammatory) IV - Asymptomatic inflammatory prostatitis
Acute kidney failure occurs when your kidneys suddenly become unable to filter waste products from your blood. When your kidneys lose their filtering ability, dangerous levels of wastes may accumulate, and your blood's chemical makeup may get out of balance. Acute kidney failure — also called acute renal failure or acute kidney injury — develops rapidly over a few hours or a few days. Acute kidney failure is most common in people who are already hospitalized, particularly in critically ill people who need intensive care. Acute kidney failure can be fatal and requires intensive treatment. However, acute kidney failure may be reversible. If you're otherwise in good health, you may recover normal or nearly normal kidney function.
Initial symptoms may include: Pain or discomfort in the upper tummy (abdomen), especially after eating. Indigestion. (Note: most people who have indigestion do not have stomach cancer.) Feeling sick, and being off food. ... Weight loss and/or loss of appetite. You may pass blood out with your stools (faeces).
Absence of a woman's monthly menstrual period is called amenorrhea. Secondary amenorrhea is when a woman who has been having normal menstrual cycles stops getting her periods for 6 months or longer. Causes Secondary amenorrhea can occur due to natural changes in the body. For example, the most common cause of secondary amenorrhea is pregnancy. Breastfeeding and menopause are also common, but natural, causes. Women who take birth control pills or who receive hormone shots such as Depo-Provera may not have any monthly bleeding. When they stop taking these hormones, their periods may not return for more than 6 months. You are more likely to have absent periods if you: Are obese Exercise too much and for long periods of time Have very low body fat (less than 15 to 17%) Have severe anxiety or emotional distress Lose a lot of weight suddenly (for example, from strict or extreme diets or after gastric bypass surgery) Other causes include: Brain (pituitary) tumors Drugs for cancer treatment Drugs to treat schizophrenia or psychosis Overactive thyroid gland Polycystic ovarian syndrome Reduced function of the ovaries
Most frozen shoulders get better on their own within 12 to 18 months. For persistent symptoms, your doctor may suggest: Steroid injections. Injecting corticosteroids into your shoulder joint may help decrease pain and improve shoulder mobility, especially in the early stages of the process. Joint distension. Injecting sterile water into the joint capsule can help stretch the tissue and make it easier to move the joint. Shoulder manipulation. In this procedure, you receive a general anesthetic, so you'll be unconscious and feel no pain. Then the doctor moves your shoulder joint in different directions, to help loosen the tightened tissue. Surgery. Surgery for frozen shoulder is rare, but if nothing else has helped, your doctor may recommend surgery to remove scar tissue and adhesions from inside your shoulder joint. Doctors usually perform this surgery with lighted, tubular instruments inserted through small incisions around your joint (arthroscopically).
Dizziness is a word that is often used to describe two different feelings. It is important to know exactly what you mean when you say "I feel dizzy," because it can help you and your doctor narrow down the list of possible problems. Lightheadedness is a feeling that you are about to faint or "pass out." Although you may feel dizzy, you do not feel as though you or your surroundings are moving. Lightheadedness often goes away or improves when you lie down. If lightheadedness gets worse, it can lead to a feeling of almost fainting or a fainting spell (syncope). You may sometimes feel nauseated or vomit when you are lightheaded. Vertigo is a feeling that you or your surroundings are moving when there is no actual movement. You may feel as though you are off balance, spinning, whirling, falling, or tilting. When you have severe vertigo, you may feel very nauseated or vomit. You may have trouble walking or standing, and you may lose your balance and fall.
Scleroderma (skleer-oh-DUR-muh) is a group of rare diseases that involve the hardening and tightening of the skin and connective tissues — the fibers that provide the framework and support for your body. In some people, scleroderma affects only the skin. But in many people, scleroderma also harms structures beyond the skin — such as blood vessels, internal organs and the digestive tract. Signs and symptoms vary, depending on which structures are affected. Scleroderma affects women more often than men and most commonly occurs between the ages of 30 and 50. While there is no cure for scleroderma, a variety of treatments can ease symptoms and improve quality of life.
Aspirin, or acetylsalicylic acid (ASA) is a salicylate drug, and is generally used as an analgesic (something that relieves pain without producing anesthesia or loss of consciousness) for minor aches and pains, to reduce fever (an antipyretic), and also as an anti-inflammatory drug.
The deep veins play a significant role in propelling blood toward the heart. The one-way valves in deep veins prevent blood from flowing backward, and the muscles surrounding the deep veins compress them, helping force the blood toward the heart, just as squeezing a toothpaste tube ejects toothpaste.
Although the Apgar score was developed in 1952 by an anesthesiologist named Virginia Apgar, you also might hear it referred to as an acronym for: Appearance, Pulse, Grimace, Activity, and Respiration. The Apgar test is usually given to a baby twice: once at 1 minute after birth, and again at 5 minutes after birth.
Sinusitis means your sinuses are inflamed. The cause can be an infection or another problem. Your sinuses are hollow air spaces within the bones surrounding the nose. They produce mucus, which drains into the nose. If your nose is swollen, this can block the sinuses and cause pain. There are several types of sinusitis, including Acute, which lasts up to 4 weeks Subacute, which lasts 4 to 12 weeks Chronic, which lasts more than 12 weeks and can continue for months or even years Recurrent, with several attacks within a year Acute sinusitis often starts as a cold, which then turns into a bacterial infection. Allergies, nasal problems, and certain diseases can also cause acute and chronic sinusitis. Symptoms of sinusitis can include fever, weakness, fatigue, cough, and congestion. There may also be mucus drainage in the back of the throat, called postnasal drip. Your health care professional diagnoses sinusitis based on your symptoms and an examination of your nose and face. You may also need imaging tests. Treatments include antibiotics, decongestants, and pain relievers. Using heat pads on the inflamed area, saline nasal sprays, and vaporizers can also help.
