A leg ulcer is simply a break in the skin of the leg, which allows air and bacteria to get into the underlying tissue. This is usually caused by an injury, often a minor one that breaks the skin. In most people such an injury will heal up without difficulty within a week or two. However, when there is an underlying problem the skin does not heal and the area of breakdown can increase in size. This is a chronic leg ulcer.
How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaffold. At the Massachusetts General Hospital in Boston, Harald Ott and his team are reusing the scaffold that nature provides. They’re stripping away all the living cells from dead hearts, before filling in the leftover matrix with healthy new cells. In this video, Brendan Maher finds out how the technique could be used to develop parts of the heart, like the aortic root and valve, for transplant.
Genes are the building blocks of heredity. They are passed from parent to child. They hold DNA, the instructions for making proteins. Proteins do most of the work in cells. They move molecules from one place to another, build structures, break down toxins, and do many other maintenance jobs. Sometimes there is a mutation, a change in a gene or genes. The mutation changes the gene's instructions for making a protein, so the protein does not work properly or is missing entirely. This can cause a medical condition called a genetic disorder. You can inherit a gene mutation from one or both parents. A mutation can also happen during your lifetime.
In your first few months of pregnancy, hormones flood your body. Your baby is still tiny but already your body is changing. Your breasts start to swell and may feel tender. Tiredness, nausea and frequent trips to the loo are common pregnancy symptoms.
A central venous catheter, also called a central line, is a long, thin, flexible tube used to give medicines, fluids, nutrients, or blood products over a long period of time, usually several weeks or more. A catheter is often inserted in the arm or chest through the skin into a large vein.
The uterus, or womb, is an important female reproductive organ. It is the place where a baby grows when a women is pregnant. There are different types of uterine cancer. The most common type starts in the endometrium, the lining of the uterus. This type of cancer is sometimes called endometrial cancer. The symptoms of uterine cancer include Unusual vaginal bleeding or discharge Trouble urinating Pelvic pain Pain during intercourse Uterine cancer usually occurs after menopause. Being obese and taking estrogen-alone hormone replacement therapy (also called menopausal hormone therapy) also increase your risk. Treatment varies depending on your overall health, how advanced the cancer is and whether hormones affect its growth. Treatment is usually a hysterectomy, which is surgery to remove the uterus. The ovaries and fallopian tubes are also removed. Other options include hormone therapy and radiation.
A peak flow meter is an inexpensive, portable, handheld device for those with asthma that is used to measure how well air moves out of your lungs. Measuring your peak flow using this meter is an important part of managing your asthma symptoms and preventing an asthma attack.
Chemotherapy (often abbreviated to chemo and sometimes CTX or CTx) is a category of cancer treatment that uses chemical substances, especially one or more anti-cancer drugs (chemotherapeutic agents) that are given as part of a standardized chemotherapy regimen.

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4.
Do you need to do a parasite cleanse? Probably... I hear from so many people suffering from symptoms of parasites - severe bloating, cramps, constipation, diarrhoea. A big problem in getting to the bottom of this (pun intended) is that the mainstream medical system really doesn’t have a way to detect, or even find most forms of parasites. They give you drugs for the symptoms, but essentially the parasites aren’t removed during that process.
To get started, you need to find your pelvic floor muscles by stopping urination in midstream. If you succeed, you have located the right muscles. Once you have located your pelvic floor muscles, tighten the contraction for about 5 seconds, before relaxing for another 5 seconds.
The removal of a clot is called an embolectomy. An embolectomy might be done during a surgery. Or it might be done with a minimally invasive procedure that uses a catheter (a thin tube that is guided through a blood vessel). This type of treatment for pulmonary embolism is used only in rare cases.
