An estimated 90% of men who have sex with men and as many as 5% to 10% of sexually active women engage in receptive anal intercourse. Often referred to simply as anal sex, anal intercourse is sexual activity that involves inserting the penis into the anus. People may engage in anal intercourse, which has health risks, because the anus is full of nerve endings, making it very sensitive. For some recipients of anal sex, the anus can be an erogenous zone that responds to sexual stimulation. For the giving partner, the anus may provide a pleasing tightness around the penis. While some people find anal sex enjoyable, the practice has downsides and requires special safety precautions. Is Anal Sex Safe? There are a number of health risks with anal sex, and anal intercourse is the riskiest form of sexual activity for several reasons, including the following: The anus lacks the natural lubrication the vagina has. Penetration can tear the tissue inside the anus, allowing bacteria and viruses to enter the bloodstream. This can result in the spread of sexually transmitted infections including HIV. Studies have suggested that anal exposure to HIV poses 30 times more risk for the receptive partner than vaginal exposure. Exposure to the human papillomavirus (HPV) may also lead to the development of anal warts and anal cancer. Using lubricants can help some, but doesn't completely prevent tearing. The tissue inside the anus is not as well protected as the skin outside the anus. Our external tissue has layers of dead cells that serve as a protective barrier against infection. The tissue inside the anus does not have this natural protection, which leaves it vulnerable to tearing and the spread of infection. The anus was designed to hold in feces. The anus is surrounded with a ring-like muscle, called the anal sphincter, which tightens after we defecate. When the muscle is tight, anal penetration can be painful and difficult. Repetitive anal sex may lead to weakening of the anal sphincter, making it difficult to hold in feces until you can get to the toilet. However, Kegel exercises to strengthen the sphincter may help prevent this problem or correct it. The anus is full of bacteria. Even if both partners do not have a sexually-transmitted infection or disease, bacteria normally in the anus can potentially infect the giving partner. Practicing vaginal sex after anal sex can also lead to vaginal and urinary tract infection
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.
Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures (BPs) lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment
Electrophysiology studies test the electrical activity of your heart to find where an arrhythmia (abnormal heartbeat) is coming from. These results can help you and your doctor decide whether you need medicine, a pacemaker, an implantable cardioverter defibrillator (ICD), cardiac ablation or surgery.
ERCP is a procedure that enables your physician to examine the pancreatic and bile ducts. A bendable, lighted tube (endoscope) about the thickness of your index finger is placed through your mouth and into your stomach and first part of the small intestine (duodenum). In the duodenum a small opening is identified (ampulla) and a small plastic tube (cannula) is passed through the endoscope and into this opening. Dye (contrast material) is injected and X-rays are taken to study the ducts of the pancreas and liver.
Mitral valve surgery is surgery to either repair or replace the mitral valve in your heart. Blood flows from the lungs and enters a pumping chamber of the heart called the left atrium. The blood then flows into the final pumping chamber of the heart called the left ventricle. The mitral valve is located between these two chambers. It makes sure that the blood keeps moving forward through the heart. You may need surgery on your mitral valve if: The mitral valve is hardened (calcified). This prevents blood from moving forward through the valve. The mitral valve is too loose. Blood tends to flows backward when this occurs. Minimally invasive mitral valve surgery is done through several small cuts. Another type of operation, open mitral valve surgery requires a larger cut.
Finding a donor heart can be difficult. The heart must be donated by someone who is brain-dead but is still on life support. The donor heart must be matched as closely as possible to your tissue type to reduce the chance that your body will reject it. You are put into a deep sleep with general anesthesia, and a cut is made through the breastbone. Your blood flows through a heart-lung bypass machine while the surgeon works on your heart. This machine does the work of your heart and lungs while they are stopped, and supplies your body with blood and oxygen. Your diseased heart is removed and the donor heart is stitched in place. The heart-lung machine is then disconnected. Blood flows through the transplanted heart, which takes over supplying your body with blood and oxygen. Tubes are inserted to drain air, fluid, and blood out of the chest for several days, and to allow the lungs to fully re-expand.
Cardiac arrest is the abrupt loss of heart function in a person who may or may not have diagnosed heart disease. The time and mode of death are unexpected. It occurs instantly or shortly after symptoms appear. Each year, more than 350,000 emergency medical services-assessed out-of-hospital cardiac arrests occur in the United States
You can decrease your risk of getting Lyme disease with some simple precautions: Cover up. ... Use insect repellents. ... Do your best to tick-proof your yard. ... Check yourself, your children and your pets for ticks. ... Don't assume you're immune. ... Remove a tick as soon as possible with tweezers.
HYSTERECTOMY RECOVERY: ALL PROCEDURES ARE NOT CREATED EQUAL Too often, women are only given the option of an open hysterectomy for conditions like large fibroids or an enlarged uterus. Surgical techniques have evolved in the last decade, but across the United States, the number of women still having open hysterectomy procedures is unnecessarily staggering. Robotic procedures are becoming more common as hospitals invest nearly $2 million in the machine. While the robot does allow surgeons who are not necessarily trained in laparoscopic procedures to perform a more minimally invasive surgery, tools cannot replace skill. There is no added benefit to the patient and the surgery can cost on average up to $2,000 more than other laparoscopic options, and in some cases much higher.
People with panic disorder have sudden and repeated attacks of fear that last for several minutes or longer. These are called panic attacks. Panic attacks are characterized by a fear of disaster or of losing control even when there is no real danger. A person may also have a strong physical reaction during a panic attack. It may feel like having a heart attack. Panic attacks can occur at any time, and many people with panic disorder worry about and dread the possibility of having another attack.
It can treat spider veins and tiny varicose veins just under the skin's surface. ... (If you have poor blood circulation feeding these tiny veins, the larger "feeder" vein must first be treated with surgery, endovenous laser or radiofrequency treatment, or sclerotherapy.) Endovenous laser treatment.
If a patient comes to you with a painful, throbbing, swollen, red face (a ''fat face'), perhaps with fever, trismus and lymphadenitis, he is probably suffering from an acute dental or oral infection, most probably an alveolar abscess. He may have: (1) An alveolar abscess begins as an infection in the bone around a non-vital infected tooth. He has severe pain, which becomes less as pus is released into more superficial tissues and his face starts to swell. After 36 hours of cellulitis he usually has a fluctuant abscess which needs draining. If drainage is delayed, the pus in his abscess discharges spontaneously through a sinus (26-8) in his gum or face, which may become chronic. First, control infection with antibiotics, and then drain the abscess, either by incising it where it is pointing, or by removing the infected tooth, which acts as a cork to prevent the pus escaping, or by doing both these things. If you remove a tooth before you have controlled the infection with antibiotics, and while his face is still severely swollen, you may spread the infection; your task will also be more difficult. (2) A periodontal abscess at the side of a tooth, caused by spread from an infected gum. (3) A pericoronal abscess caused by infection of the gum over the crown of an unerupted and impacted tooth, usually a lower third molar (''an infected wisdom tooth'). Often, an abscess does not form, and the gum round the tooth is merely inflamed.
Glomerular filtration is the first step in making urine. It is the process that your kidneys use to filter excess fluid and waste products out of the blood into the urine collecting tubules of the kidney, so they may be eliminated from your body.
