Thyroid nodules increase with age and are present in almost 10% of the adult population. Autopsy studies reveal the presence of thyroid nodules in 50% of the population, so they are fairly common. 95% of solitary thyroid nodules are benign, and therefore, only 5% of thyroid nodules are malignant.
An antisperm antibody test looks for special proteins (antibodies) that fight against a man's sperm in blood, vaginal fluids, or semen. The test uses a sample of sperm and adds a substance that binds only to affected sperm. Semen can cause an immune system response in either the man's or woman's body. The antibodies can damage or kill sperm. If a high number of sperm antibodies come into contact with a man's sperm, it may be hard for the sperm to fertilize an egg. The couple has a hard time becoming pregnant. This is called immunologic infertility.
The Estech COBRA Fusion™ 150 Surgical Ablation System combines intuitive, real-time TCRF (Temperature Controlled Radiofrequency) energy control with proprietary Versapolar technology. Versapolar™ energy delivery is the first of its kind—an adaptable and effective platform that can deliver both bipolar and monopolar energy so that surgeons can easily and efficiently create reproducible transmural lesions with more flexibility, confidence and control.
Dilation and curettage (D&C) is a procedure to remove tissue from inside your uterus. Doctors perform dilation and curettage to diagnose and treat certain uterine conditions — such as heavy bleeding — or to clear the uterine lining after a miscarriage or abortion. In a dilation and curettage — sometimes spelled "dilatation" and curettage — your doctor uses small instruments or a medication to open (dilate) your cervix — the lower, narrow part of your uterus. Your doctor then uses a surgical instrument called a curette to remove uterine tissue. Curettes used in a D&C can be sharp or use suction

Breast abscesses are often linked to mastitis – a condition that causes breast pain and swelling (inflammation), and usually affects women who are breastfeeding. Infections can occur during breastfeeding if bacteria enter your breast tissue, or if the milk ducts (tiny tubes) become blocked. This can cause mastitis which, if not treated, can result in an abscess forming. Women who aren't breastfeeding can also develop mastitis if bacteria enter the milk ducts through a sore or cracked nipple, or a nipple piercing. White blood cells are sent to attack the infection, which causes tissue at the site of the infection to die. This creates a small, hollow area that fills with pus (an abscess).
People whose back or neck pain has not been relieved by back surgery or other treatments may have another option to consider: spinal cord stimulation. Around the world, some 14,000 patients undergo spinal cord stimulator implants each year. Spinal cord stimulation (SCS) delivers mild electrical stimulation to nerves along the spinal column, modifying or blocking nerve activity in a non-medicinal way to minimize the sensation of pain reaching the brain.
Pulmonary edema is a condition caused by excess fluid in the lungs. This fluid collects in the numerous air sacs in the lungs, making it difficult to breathe. In most cases, heart problems cause pulmonary edema. But fluid can accumulate for other reasons, including pneumonia, exposure to certain toxins and medications, trauma to the chest wall, and exercising or living at high elevations. Pulmonary edema that develops suddenly (acute pulmonary edema) is a medical emergency requiring immediate care. Although pulmonary edema can sometimes prove fatal, the outlook improves when you receive prompt treatment for pulmonary edema along with treatment for the underlying problem. Treatment for pulmonary edema varies depending on the cause but generally includes supplemental oxygen and medications.
An abscess is an infectious process characterized by a collection of pus surrounded by inflamed tissue. [1, 2] Abscesses can form anywhere in the body, from a superficial skin (subcutaneous) abscess to deep abscesses in muscle, organs, or body cavities. Patients with subcutaneous skin abscesses present clinically as a firm, localized, painful, erythematous swelling that becomes fluctuant (see the image below).
