The heart weighs between 7 and 15 ounces (200 to 425 grams) and is a little larger than the size of your fist. By the end of a long life, a person's heart may have beat (expanded and contracted) more than 3.5 billion times. In fact, each day, the average heart beats 100,000 times, pumping about 2,000 gallons. Your heart is located between your lungs in the middle of your chest, behind and slightly to the left of your breastbone (sternum). A double-layered membrane called the pericardium surrounds your heart like a sac. The outer layer of the pericardium surrounds the roots of your heart's major blood vessels and is attached by ligaments to your spinal column, diaphragm, and other parts of your body. The inner layer of the pericardium is attached to the heart muscle. A coating of fluid separates the two layers of membrane, letting the heart move as it beats. Your heart has 4 chambers. The upper chambers are called the left and right atria, and the lower chambers are called the left and right ventricles. A wall of muscle called the septum separates the left and right atria and the left and right ventricles. The left ventricle is the largest and strongest chamber in your heart. The left ventricle's chamber walls are only about a half-inch thick, but they have enough force to push blood through the aortic valve and into your body.
A Cesarean section (C-section) is surgery to deliver a baby. The baby is taken out through the mother's abdomen. In the United States, almost one in three women has their babies this way. Some C-sections are planned, but many are done when unexpected problems happen during delivery. Reasons for a C-section may include
An abscess is a tender mass generally surrounded by a colored area from pink to deep red. Abscesses are often easy to feel by touching. The middle of an abscess is full of pus and debris. Painful and warm to touch, abscesses can show up any place on your body. The most common sites are in your armpits (axillae), areas around your anus and vagina(Bartholin gland abscess), the base of your spine (pilonidal abscess), around a tooth (dental abscess), and in your groin. Inflammation around a hair follicle can also lead to the formation of an abscess, which is called a boil (furuncle).
Learn one of the hidden reasons why you still have a thyroid symptoms. If your lab results are "normal"--then why do you still have thyroid symptoms like: * Tired, sluggish * Can't lose weight even with exercise * Feel cold—hands, feet, or all over * Require excessive amounts of sleep to function properly * Increase in weight gain even with low-calorie diet * Gain weight easily * Difficult, infrequent bowel movements * Depression, lack of motivation * Morning headaches that wear off as the day progresses * Outer third of eyebrow thins * Thinning of hair on scalp, face or genitals or hair loss * Dryness of skin and/or scalp * Mental sluggishness * Nervousness and emotional * Insomnia * Night sweats
Osteoporosis is a disease that weakens bones over time. Because of this, it puts you at risk for breaking a bone. Postmenopausal osteoporosis is the most common form of osteoporosis. It affects many women after menopause, leaving some women at high risk for fracture. - See more at: https://www.prolia.com/postmenopausal-osteoporosis/deeper-look/?WT.z_co=A&WT.z_in=PMO&WT.z_ch=PDS&WT.z_st=Site1&WT.z_mt=Broad&WT.z_pdskw=www%20osteoporosis&WT.z_ag=Osteoporosis%20Information%20-%20Broad&WT.z_se=G&WT.srch=1&WT.z_prm=DSE__&WT.mc_id=A_PMO_PDS_G_DSE___Broad_www%20osteoporosis_Osteoporosis%20Information%20-%20Broad#sthash.x5Ys3Now.dpuf
Haemorrhoids is one of the most common problems seen in surgical OPD. Open haemorrhoidectomy has remained the gold standard for a long time with a high post-operative morbidity. The quest for a better understanding of the pathology of haemorrhoids resulted in the evolvement of stapler haemorrhoidopexy. Our aim is to study the efficacy of stapler haemorrhoidopexy with regards to role of immediate post-operative morbidity. A prospective study of 50 patients (n = 50) with the second- and third-degree symptomatic haemorrhoids was done. The mean age of the patients was 44.1 years. Fourteen patients had co-morbid conditions. The average duration of the operation was 29 min. Patients with the second-degree haemorrhoids had higher rate of complication. The complication rate was 32%. Three patients had urinary retention. Two patients had minor bleeding, and one patient experienced transient discharge. The mean analgesic requirement was 2.4 tramadol, 50 mg injections. Ten patients had significant post-operative pain. Average length of hospital stay was 2.7 days. There were no symptomatic recurrences till date.
First described by Aubaniac in 1952, central venous catheterization, or central line placement, is a time-honored and tested technique of quickly accessing the major venous system. Benefits over peripheral access include greater longevity without infection, line security in situ, avoidance of phlebitis, larger lumens, multiple lumens for rapid administration of combinations of drugs, a route for nutritional support, fluid administration, and central venous pressure (CVP) monitoring. Central vein catheterization is also referred to as central line placement. Overall complication rates are as high as 15%, [1, 2, 3, 4] with mechanical complications reported in 5-19% of patients, [5, 6, 7] infectious complications in 5-26%, [1, 2, 4] and thrombotic complications in 2-26%. [1, 8] These complications are all potentially life-threatening and invariably consume significant resources to treat. Placement of a central vein catheter is a common procedure, and house staff require substantial training and supervision to become facile with this technique. A physician should have a thorough foreknowledge of the procedure and its complications before placing a central vein catheter. The supraclavicular approach was first put into clinical practice in 1965 and is an underused method for gaining central access. It offers several advantages over the infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-side approach offers a straighter path into the subclavian vein. In addition, this site is often more accessible during cardiopulmonary resuscitation (CPR) and during active surgical cases. Finally, in patients who are obese, this anatomic area is less distorted.
Pharyngitis is caused by swelling in the back of the throat (pharynx) between the tonsils and the voice box (larynx). Most sore throats are caused by colds, the flu, coxsackie virus or mono (mononucleosis). Bacteria that can cause pharyngitis in some cases: Strep throat is caused by group A streptococcus.
According to a Danish study , frequent sex may help prevent pre-eclampsia. Researchers believe it's because of a protein found in sperm that can regulate the body's immune system. Yet because the cause of preeclampsia is unknown, it's important to keep your prenatal visits and talk to your doctor about your risk.
This test stimulates your acoustic nerve by delivering cold or warm water or air into your ear canal. When cold water or air enters your ear and the inner ear changes temperature, it should cause fast, side-to-side eye movements called nystagmus. The test is done in the following way: Before the test, your ear, especially the eardrum, will be checked. This is to make sure it is normal. One ear is tested at a time. A small amount of cold water or air is gently delivered into one of your ears. Your eyes should show an involuntary movement called nystagmus. Then they should turn away from that ear and slowly back. If water is used, it is allowed to drain out of the ear canal. Next, a small amount of warm water or air is gently delivered into the same ear. Again, your eyes should show nystagmus. Then they should turn toward that ear and slowly back. Your other ear is tested in the same way.

Antisocial personality disorder (ASPD) is defined by the American Psychiatric Association's Axis II (personality disorders) of the Diagnostic and Statistical Manual (DSM-IV-TR) as "a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood." Antisocial personality disorder is sometimes wrongly referred to as psychopathy or sociopathy. Currently, neither psychopathy nor sociopathy are valid diagnoses described in the Diagnostic and Statistical Manual of Mental Disorders, and the ICD-10 of the World Health Organization also lacks psychopathy as a diagnostic disorder. Psychopathy is normally seen as a subset of the antisocial personality disorder, but Blair believes that the antisocial personality disorder and psychopathy may be separate conditions altogether.
Nuclear Transfer is a form of cloning. The steps involve removing the DNA from an oocyte and while(unfertilized egg), and injecting the nucleus which contains the DNA to be cloned. In rare instances, the newly constructed cell will divide normally, replicating the new DNA while remaining
