Debulking is the surgical removal of part of a malignant tumour which cannot be completely excised, so as to enhance the effectiveness of radiation or chemotherapy. It is used only in specific malignancies, as generally partial removal of a tumor is not considered a worthwhile intervention. Ovarian carcinoma and some types of brain tumor are debulked prior to commencing radio- or chemotherapy. It may also be used in the case of slow growth tumors to shift tumor cells from phase of cell cycle to replicative pool.

Sex reassignment surgery for male-to-female involves reshaping the male genitals into a form with the appearance of, and, as far as possible, the function of female genitalia. Prior to any surgeries, patients usually undergo hormone replacement therapy (HRT), and, depending on the age at which HRT begins, facial hair removal. There are associated surgeries patients may elect to, including facial feminization surgery, breast augmentation, and various other procedures
FUE (follicular unit extraction) is a minimally invasive method in hair transplantation. Unlike strip harvesting, the traditional technique in which a strip of skin is removed from a donor site and cut into individual units, FUE uses an instrument to remove multiple groups of one to four hairs. The great thing about FUE is that there’s no linear scar. The downside is that a fewer number of hair grafts can be gathered per session.
Low potassium (hypokalemia) refers to a lower than normal potassium level in your bloodstream. Potassium is a chemical (electrolyte) that is critical to the proper functioning of nerve and muscles cells, particularly heart muscle cells. Normally, your blood potassium level is 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life-threatening and requires urgent medical attention.
Sodium levels are tightly controlled in a healthy individual by regulation of urine concentration and an intact thirst mechanism. Hypernatremia (defined as a serum sodium level >145 mEq/L) is rare in patients with preserved thirst mechanism. When hypernatremia does occur, it is associated with a high mortality rate (>50% in most studies). Given this high mortality rate, the emergency physician must be able to recognize and treat this condition. This article discusses the patients in whom hypernatremia should be suspected and how to initiate workup and administer appropriate treatment. In general, hypernatremia can be caused by derangement of the thirst response or altered behavioral response thereto (primarily psychiatric patients, and elderly patients who are institutionalized), impaired renal concentrating mechanism (diabetes insipidus [DI]) secondary to kidney pathology (nephrogenic DI) or difficulty with the neurohormonal control of this concentrating mechanism (central DI), or by losses of free water from other sources.
Menopause is defined as occurring 12 months after your last menstrual period and marks the end of menstrual cycles. Menopause can happen in your 40s or 50s, but the average age is 51 in the United States. Menopause is a natural biological process. Although it also ends fertility, you can stay healthy, vital and sexual. Some women feel relieved because they no longer need to worry about pregnancy. Even so, the physical symptoms, such as hot flashes, and emotional symptoms of menopause may disrupt your sleep, lower your energy or — for some women — trigger anxiety or feelings of sadness and loss. Don't hesitate to seek treatment for symptoms that bother you. Many effective treatments are available, from lifestyle adjustments to hormone therapy.
A disease of the immune system due to infection with HIV. HIV destroys the CD4 T lymphocytes (CD4 cells) of the immune system, leaving the body vulnerable to life-threatening infections and cancers. Acquired immunodeficiency syndrome (AIDS) is the most advanced stage of HIV infection. To be diagnosed with AIDS, a person with HIV must have an AIDS-defining condition or have a CD4 count less than 200 cells/mm³ (regardless of whether the person has an AIDS-defining condition).
In a small but promising Phase II clinical trial of breast cancer treatment, cryoablation killed 25 early-stage tumors in 13 women. The tumors ranged in size from .5 cm (very small) to 5.8 cm (very large), with an average size of 1.7cm. Patients were first given a local anesthesia with mild sedation before physicians used ultrasound with or without computed tomography (CT) imaging to guide needle-like probes to deliver very low temperature gas to the tumor site. The ultra-cold gas forms a ball of ice around the probe tip, then expands and destroys surrounding tumor cells. A harmless saline solution was first injected into the chest wall and skin of the breast to protect the tissue surrounding the tumor from the freezing effects. Patients experienced very little pain and most healed completely within six months with no complications and with little or no scarring. The cryotherapy margins of each participant were biopsied immediately after the procedures, and all were negative, with no evidence of cancerous tissue. All 13 patients were without recurrence at an average of 18 months and up to five years following the procedure. These results are promising, but larger studies with lengthier follow-up are needed to determine whether cryotherapy as effective as lumpectomy. A study involving cryoablation of mouse tumors at the University of Michigan Comprehensive Cancer Center found that the freezing procedure also works like a vaccine, boosting the immune system to reduce the likelihood of recurrence. Just how quickly the tumor was frozen made a difference: a 30-second freeze killed tumors and also boosted the immune system, inhibiting metastases to the lungs. A slower freezing lasting several minutes destroyed tumors just as effectively, but actually suppressed the immune system, resulting in greater metastases to the lungs.
Men need to know that breast cancer is not limited to women. Possible symptoms of breast cancer to watch for include: A lump or swelling, which is usually (but not always) painless Skin dimpling or puckering Nipple retraction (turning inward) Redness or scaling of the nipple or breast skin Discharge from the nipple Sometimes a breast cancer can spread to lymph nodes under the arm or around the collar bone and cause a lump or swelling there, even before the original tumor in the breast tissue is large enough to be felt. These changes aren't always caused by cancer. For example, most breast lumps in men are caused by gynecomastia (a harmless enlargement of breast tissue). Still, if you notice any breast changes, you should see a health care professional as soon as possible.
What is a mole? Many people refer to a mole as any dark spot or irregularity in the skin. Doctors use different terms. But the following types of skin marks such as these are not treated the same way moles are and are not discussed here: Birthmarks Abnormal formations of blood vessels (hemangiomas) Keratoses (benign or precancerous spots, which appear after about age 30 years)
The most common symptoms noticed by people with haemochromatosis (inherited iron overload disorder) are • Fatigue, weakness and lethargy • Joint pains leading to osteoarthritis * Other symptoms include: • Abdominal pain • Diabetes • Liver disorders; enlarged liver, cirrhosis • Sexual disorders; loss of sex drive in both male and female, impotence in men, absent or scanty menstrual periods and early menopause in women • Decrease in body hair • Discolouration or bronzing of the skin • Cardiomyopathy; disease of the heart muscle • Neurological/psychiatric disorders; impaired memory, mood swings, severe irritability, depression. These symptoms, if present, take time to develop. No two people are alike and symptoms will vary from person to person. Some people never develop any symptoms at all. All of the symptoms of haemochromatosis can also be caused by other medical conditions or even just the stresses of modern life. They develop slowly and people often do not notice what is happening for a long time. This can make haemochromatosis difficult to diagnose. Symptoms are caused by high levels of iron stored in the body. One indicator of the level of iron stored is serum ferritin. If iron stores are high the serum ferritin level will be high, but serum ferritin levels can also be raised by other factors. The normal range is 20 – 300 micrograms per litre (µg/L) for men and 10 – 200 µg/L for women. There is strong medical evidence of a potential for significant organ damage when iron stores cause serum ferritin levels above 1,000 µg/L. However some people seem to experience symptoms with levels between 300 and 1,000 µg/L. Higher levels are more likely to be associated with more severe symptoms. If haemochromatosis is diagnosed and treated before serious iron overload and significant damage occurs, most symptoms will decrease or disappear. However there is evidence that treatment may not alleviate arthritis symptoms.
What is idiopathic intracranial hypertension? Idiopathic intracranial hypertension (IIH) is a disorder that results from an increase in the pressure of the Cerebro-Spinal Fluid (CSF) that cushions and protects the brain and spinal cord. The CSF is constantly produced in the brain and reabsorbed back into the bloodstream at a fairly constant rate. This allows the fluid pressure around the brain to remain constant. What are the symptoms of idiopathic intracranial hypertension? Headaches that are generally nonspecific in location, type and frequency and can be associated with nausea and vomiting. Pulsatile tinnitus is a rhythmic or pulsating ringing heard in one or both ears. Horizontal double vision can be a sign of pressure on the 6th cranial nerve(s). Nonspecific radiating pain in the arms or legs (radicular pain). Transient obscurations of vision (TOV), which are temporary dimming or complete blacking out of vision. Visual field defects. These defects can occur in the central as well as the peripheral vision. Loss of color vision. What causes idiopathic intracranial hypertension? The cause is usually not known. A common explanation for increased pressure is a problem with the reabsorption of this fluid back into the body, which causes the pressure to increase. Sometimes the cause is determined and is referred to as “secondary” intracranial hypertension.
A sleep disorder, or somnipathy, is a medical disorder of the sleep patterns of a person or animal. Some sleep disorders are serious enough to interfere with normal physical, mental, social and emotional functioning. Polysomnography and actigraphy are tests commonly ordered for some sleep disorders.
Catheter ablation is a minimally invasive procedure to treat atrial fibrillation. It can relieve symptoms and improve quality of life. During an ablation, the doctor destroys tiny areas in the heart that are firing off abnormal electrical impulses and causing atrial fibrillation. You will be given medicine to help you relax. A local anesthetic will numb the site where the catheter is inserted. Sometimes, general anesthesia is used. The procedure is done in a hospital where you can be watched carefully. Thin, flexible wires called catheters are inserted into a vein, typically in the groin or neck, and threaded up into the heart. There is an electrode at the tip of the wires. The electrode sends out radio waves that create heat. This heat destroys the heart tissue that causes atrial fibrillation or the heart tissue that keeps it happening. Another option is to use freezing cold to destroy the heart tissue. Sometimes, abnormal impulses come from inside a pulmonary vein and cause atrial fibrillation. (The pulmonary veins bring blood back from the lungs to the heart.) Catheter ablation in a pulmonary vein can block these impulses and keep atrial fibrillation from happening. View a slideshow of catheter ablation to see how the heart's electrical system works, how atrial fibrillation happens, and how ablation is done. Atrial Fibrillation: Should I Have Catheter Ablation? AV node ablation AV node ablation is a slightly different type of ablation procedure for atrial fibrillation. AV node ablation can control symptoms of atrial fibrillation in some people. It might be right for you if medicine has not worked, catheter ablation did not stop your atrial fibrillation, or you cannot have catheter ablation. With AV node ablation, the entire atrioventricular (AV) node is destroyed. After the AV node is destroyed, it can no longer send impulses to the lower chambers of the heart (ventricles). This controls atrial fibrillation symptoms. After AV node ablation, a permanent pacemaker is needed to regulate your heart rhythm. Nodal ablation can control your heart rate and reduce your symptoms, but it does not prevent or cure atrial fibrillation. AV node ablation helps about 9 out of 10 people.1 The procedure has a low risk of serious problems.2 View a slideshow of AV node ablation to see how the heart's electrical system works, how atrial fibrillation happens, and how AV node ablation is performed.

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.
