The hair transplant surgeon can accurately estimate the number of follicular grafts that can be obtained from dissecting a donor strip of a given size. The same number of follicular units can be used to cover a specific size bald area regardless of the patient's actual hair density.
A pneumothorax (noo-moe-THOR-aks) is a collapsed lung. A pneumothorax occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. In most cases, only a portion of the lung collapses. A pneumothorax can be caused by a blunt or penetrating chest injury, certain medical procedures, or damage from underlying lung disease. Or it may occur for no obvious reason. Symptoms usually include sudden chest pain and shortness of breath. On some occasions, a collapsed lung can be a life-threatening event. Treatment for a pneumothorax usually involves inserting a flexible tube or needle between the ribs to remove the excess air. However, a small pneumothorax may heal on its own.
Vesicoureteral (ves-ih-koe-yoo-REE-tur-ul) reflux is the abnormal flow of urine from your bladder back up the tubes (ureters) that connect your kidneys to your bladder. Normally, urine flows only down from your kidneys to your bladder. Vesicoureteral reflux is usually diagnosed in infants and children. The disorder increases the risk of urinary tract infections, which, if left untreated, can lead to kidney damage. Vesicoureteral reflux can be primary or secondary. Children with primary vesicoureteral reflux are born with a defect in the valve that normally prevents urine from flowing backward from the bladder into the ureters. Secondary vesicoureteral reflux is due to a urinary tract malfunction, often caused by infection. Children may outgrow primary vesicoureteral reflux. Treatment, which includes medication or surgery, aims at preventing kidney damage.
Anemia is a condition in which you don't have enough healthy red blood cells to carry adequate oxygen to the body's tissues. Having anemia may make you feel tired and weak. There are many forms of anemia, each with its own cause. Anemia can be temporary or long term, and it can range from mild to severe. See your doctor if you suspect you have anemia because it can be a warning sign of serious illness. Treatments for anemia range from taking supplements to undergoing medical procedures. You may be able to prevent some types of anemia by eating a healthy, varied diet.
Graves disease is an autoimmune disorder that leads to an overactive thyroid gland (hyperthyroidism). An autoimmune disorder is a condition that occurs when the immune system mistakenly attacks healthy tissue. Causes The thyroid gland is an important organ of the endocrine system. The gland is located at the front of the neck above where the collarbones meet. This gland releases the hormones thyroxine (T4) and triiodothyronine (T3), which control body metabolism. Controlling metabolism is important for regulating mood, weight, and mental and physical energy levels. When the body makes too much thyroid hormone, the condition is called hyperthyroidism. (An underactive thyroid leads to hypothyroidism.) Graves disease is the most common cause of hyperthyroidism. It is due to an abnormal immune system response that causes the thyroid gland to produce too much thyroid hormone. Graves disease is most common in women over age 20. But the disorder can occur at any age and can affect men as well. Symptoms Younger people may have these symptoms: Anxiety or nervousness, as well as problems sleeping Breast enlargement in men (possible) Problems concentrating Fatigue Frequent bowel movements Hair loss Heat intolerance and increased sweating Increased appetite, despite having weight loss Irregular menstrual periods in women Muscle weakness of the hips and shoulders Moodiness, including irritability and anger Rapid or irregular heartbeat Shortness of breath with activity Tremor Many people with Graves disease have problems with their eyes: The eyeballs may seem to be bulging out and may be painful. Eyes can feel irritated and be tearing. Double vision may be present. Older people may have these symptoms: Rapid or irregular heartbeat Chest pain Memory loss Weakness and fatigue
The key difference between monophasic and biphasic defibrillator is that the monophasic defibrillator is a type of defibrillation waveform where a shock is delivered to the heart from one vector as shown below. Whereas, in biphasic defibrillation, shock is delivered to the heart via two vectors.
Thalassemia (thal-uh-SEE-me-uh) is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.
The virus was first discovered in 1964 when Sir Michael Anthony Epstein and Ms. Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, the virus was linked to the disease infectious mononucleosis. Infection with Epstein-Barr virus (EBV) is common and usually occurs in childhood or early adulthood. EBV is the cause of infectious mononucleosis (also termed "mono"), an illness associated with fever, sore throat, swollen lymph nodes in the neck, and sometimes an enlarged spleen. It is also known as human herpes virus 4. Although EBV can cause mononucleosis, not everyone infected with the virus will get mononucleosis. Less commonly, EBV can cause more serious disease. Symptoms caused by EBV are usually mild and self-limited, but the virus persists in the body for life. It can be reactivated quietly without causing symptoms and may contaminate saliva. Thus, otherwise healthy people can spread the virus to uninfected people through kissing or sharing
The increased risk of thrombosis in patients with active cancer has multiple causes. Acute thrombosis of the aorta is an exceedingly rare but potentially devastating complication in patients with cancer receiving cisplatin-based chemotherapy. Prompt diagnosis and definitive treatment are imperative to decrease morbidity and mortality. Early diagnosis is difficult because initial presentation is often nonspecific, requiring a high degree of clinical suspicion. We report 4 cases of acute thrombosis of the abdominal aorta in patients with cancer receiving cisplatin-based chemotherapy. We review the clinical aspects, recommended investigation, and treatment of this potentially fatal complication.
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.
Diabetic ketoacidosis is a serious complication of diabetes that occurs when your body produces high levels of blood acids called ketones. The condition develops when your body can't produce enough insulin. Insulin normally plays a key role in helping sugar (glucose) — a major source of energy for your muscles and other tissues — enter your cells. Without enough insulin, your body begins to break down fat as fuel. This process produces a buildup of acids in the bloodstream called ketones, eventually leading to diabetic ketoacidosis if untreated. If you have diabetes or you're at risk of diabetes, learn the warning signs of diabetic ketoacidosis — and know when to seek emergency care.
Lung cancer is a type of cancer that begins in the lungs. Your lungs are two spongy organs in your chest that take in oxygen when you inhale and release carbon dioxide when you exhale. Lung cancer is the leading cause of cancer deaths in the United States, among both men and women. Lung cancer claims more lives each year than do colon, prostate, ovarian and breast cancers combined. People who smoke have the greatest risk of lung cancer. The risk of lung cancer increases with the length of time and number of cigarettes you've smoked. If you quit smoking, even after smoking for many years, you can significantly reduce your chances of developing lung cancer.
Most women have between 11 and 13 menstrual periods each year. You may be different: You may have more or fewer. Missed or irregular periods must be looked at in terms of what is normal for you. Menstrual periods are often irregular during the first few years after menstruation starts. It may take several years for the hormones that control menstruation to reach a balance. Menstrual periods also may be very irregular at the other end of the menstrual years. Many women realize that they are approaching perimenopause and menopause when their otherwise regular periods become irregular. Menopause occurs when it has been 12 months since you had a menstrual period. Pregnancy is the most common cause of a missed period. If you might be pregnant, treat yourself as if you are pregnant until you know for sure. Use a home pregnancy test as the first step to finding out whether you are pregnant.
Specific treatment for menorrhagia is based on a number of factors, including: Your overall health and medical history The cause and severity of the condition Your tolerance for specific medications, procedures or therapies The likelihood that your periods will become less heavy soon Your future childbearing plans Effects of the condition on your lifestyle Your opinion or personal preference Drug therapy for menorrhagia may include: Iron supplements. If you also have anemia, your doctor may recommend that you take iron supplements regularly. If your iron levels are low but you're not yet anemic, you may be started on iron supplements rather than waiting until you become anemic. Nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs, such as ibuprofen (Advil, Motrin IB, others) or naproxen (Aleve), help reduce menstrual blood loss. NSAIDs have the added benefit of relieving painful menstrual cramps (dysmenorrhea). Tranexamic acid. Tranexamic acid (Lysteda) helps reduce menstrual blood loss and only needs to be taken at the time of the bleeding. Oral contraceptives. Aside from providing birth control, oral contraceptives can help regulate menstrual cycles and reduce episodes of excessive or prolonged menstrual bleeding. Oral progesterone. When taken for 10 or more days of each menstrual cycle, the hormone progesterone can help correct hormone imbalance and reduce menorrhagia. The hormonal IUD (Mirena). This intrauterine device releases a type of progestin called levonorgestrel, which makes the uterine lining thin and decreases menstrual blood flow and cramping. If you have menorrhagia from taking hormone medication, you and your doctor may be able to treat the condition by changing or stopping your medication.
Can the flu be treated? Yes. There are prescription medications called “antiviral drugs” that can be used to treat flu illness. What are antiviral drugs? Antiviral drugs are prescription medicines (pills, liquid, an inhaled powder, or an intravenous solution) that fight against the flu in your body. Antiviral drugs are not sold over-the-counter. You can only get them if you have a prescription from your doctor or health care provider. Antiviral drugs are different from antibiotics, which fight against bacterial infections. What should I do if I think I have the flu? If you get the flu, antiviral drugs are a treatment option. Check with your doctor promptly if you are at high risk of serious flu complications (see box below for the full list of high risk factors). Flu symptoms can include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. Your doctor may prescribe antiviral drugs to treat your flu illness. Should I still get a flu vaccine? Yes. Antiviral drugs are not a substitute for getting a flu vaccine. While flu vaccine can vary in how well it works, a flu vaccine is the first and best way to prevent seasonal influenza. Antiviral drugs are a second line of defense to treat the flu (including seasonal flu and variant flu viruses) if you get sick.
Neck pain is a common complaint. Neck muscles can be strained from poor posture — whether it's leaning over your computer or hunching over your workbench. Osteoarthritis also is a common cause of neck pain. Rarely, neck pain can be a symptom of a more serious problem. Seek medical care if your neck pain is accompanied by numbness or loss of strength in your arms or hands or if you have shooting pain into your shoulder or down your arm
