A parasitic twin (also known as an asymmetrical or unequal conjoined twin) is the result of the processes that produce vanishing twins and conjoined twins, and may represent a continuum between the two. Parasitic twins occur when a twin embryo begins developing in utero, but the pair does not fully separate, and one embryo maintains dominant development at the expense of the other. Unlike conjoined twins, one ceases development during gestation and is vestigial to a mostly fully-formed, otherwise healthy individual twin. The undeveloped twin is defined as parasitic, rather than conjoined, because it is incompletely formed or wholly dependent on the body functions of the complete fetus. The independent twin is called the autosite.

When your arteries cannot supply enough blood to your heart, your doctor may recommend coronary artery bypass graft (CABG) surgery. One of the most common heart surgeries in the United States, CABG surgery restores blood flow to your heart. Approximately every 10 minutes, someone has beating heart or "off-pump" bypass surgery1. Beating heart bypass surgery is — in simple terms — bypass surgery that is performed on your heart while it is beating. Your heart will not be stopped during surgery. You will not need a heart-lung machine. Your heart and lungs will continue to perform during your surgery. Surgeons use a tissue stabilization system to immobilize the area of the heart where they need to work. Beating heart bypass surgery is also called Off Pump Coronary Artery Bypass Surgery (OPCAB). Both OPCAB and conventional on-pump surgery restore blood flow to the heart. However, off-pump bypass surgery has proven to reduce side effects in certain types of patients.

Nasal catheter YAMIK - is a new drug delivery sistem for topical treatment for sinusitis. The introduction of a large volume of the #drugsolution directly into all the paranasal #sinuses - provides new opportunities in the #treatment of #sinusitis! #YamikprocedureNasal catheter YAMIK is a new device for topical sinonasal delivery of medication during rhinosinusitis treatment. Administration of therapeutic solution with YAMIK catheter is called YAMIK procedure. The following features differs YAMIK procedure from all other topical sinonasal delivery techniques: - Medication is delivered into the all paranasal sinuses at one side of nose regardless of their involvement in the inflammatory disease. -Specific position of patient’s head. Patient should lay on the side of of the sinuses, into which solution will be administered. This position is physiological and comfortable for patients, including children and elders. The LHL position was suggested to be the most favorable position for patients to adopt - Therapeutic solutions reliably penetrates into without previous sinus surgery sinuses with natural ostia size. - Paranasal sinuses are filling with medicinal solution by gravity. To accelerate process, it is used small pressure gradient, which created by motion of syringe plunger with amplitude 1 - 2 ml during administration of solution. - It is provided contact of the whole sino-nasal mucosa with medication. - Prolonged time of the contact of sino-nasal mucosa with medicine provides administration of the therapeutically significant dose. Therapeutic solution administered into paranasal sinuses is considered as a STORE. Thanks to affect mucociliary clearance, therapeutic solution is gradually evacuated from sinuses through ostia. Thereby, prolonged nasal irrigation is performed. - Due to extended contact with saline (NaCl 0,9%), viscous colloidal pathological substance filling paranasal sinuses is dissolved. As a result, its viscosity decreases, and substance is removing by mucociliary clearance. Thereby, drainage function of the ostia are returned some time after finish YAMIK method procedure. -The procedure is performing under local anesthesia. - There is no need in active involvement of the patient. Blowing, pronouncing any sounds like “cuckoo”, holding any things and so on is unnecessary. If is performed by a qualified medical professional the procedure is more effective. - Medication contacts only with nasal passages and paranasal sinuses. Thus, it is provided topical drug therapy. - YAMIK procedure is call sinonasal delivery techniques of a therapeutic solution. It differs from nasal techniques, because medicinal solution contacts not only with nasal mucosa, but with mucous membrane of paranasal sinuses. - The only used drug formulation is a solution. - It is possible non-invasive sample extraction from mucosa of paranasal sinuses (for bacteriological, immunological, cytological and a number of others investigation methods).

Liposuction is a surgical procedure that is done to remove fat deposits from underneath the skin. Common areas that are treated: the abdomen, buttocks, thighs, upper arms, chest and neck. (use medical graphic of body with labeled parts) The procedure is usually done as an outpatient under some combination of local anesthesia and/or sedation:. This means you are awake but relaxed and pain free. Depending on the number of areas to be treated and the specific technique selected, it may take from one to several hours. A small incision (cut) is made through the skin near the area of the fat deposit. Multiple incisions may be needed if a wide area or multiple areas are being done. A long hollow tube called a cannula will be inserted through this incision. Prior to inserting the cannula, the doctor may inject a solution of salt water that contains an anesthetic (numbing) medication and another medication to decrease bleeding. The cannula is then inserted and moved under the skin in a way to loosen the fat deposits so they may be suctioned out. Because a significant amount of body fluid is removed with the fat, an intravenous (through the veins) fluid line will be kept going during the procedure.

A recent technique called “ultrasound-assisted lipoplasty” uses a special cannula that liquefies the fat cells with ultrasonic energy. You should ask your doctor which technique he/she will use and how it will affect the type of anesthesia you will need and the length of the procedure.

Why is this procedure performed?
Liposuction is done to restore a more normal contour to the body. The procedure is sometimes described as body sculpting. It should be limited to fat deposits that are not responsive to diet and exercise. It is suggested that you should be within 20of your ideal body weight at the time of surgery. If you are planning to lose weight you should delay this procedure. This is not obesity surgery. The maximum amount of fat that can be removed is usually less than 10 pounds. The best results are achieved in people who still have firm and elastic skin. Although rare, there are risks and complications that can occur with liposuction. You should be aware that all the complications are increased if you are a smoker. You will need to quit smoking or at least avoid smoking for a month before and after surgery. If you have had prior surgeries near any of the areas to be treated, this may increase the risk of complications and you should discuss this with your doctor. Any history of heart disease, diabetes, bleeding problems or blood clots in your legs may make you more prone to post-operative problems and you should discuss these with your doctor. Finally, as with any cosmetic procedure it is important to have realistic expectations. The goals, limitations, and expectations of the procedure should be discussed openly and in detail with your doctor. Most insurance companies do not cover cosmetic surgery.

What should I expect during the post-operative period?
After surgery you should be able to go home but you will need someone to drive you. In the first few days after surgery it is common for the incisions to drain fluid and you will have to change dressings frequently. Fresh blood is not usual and if you have any bleeding you should call your doctor immediately. In some cases a small tube may have been placed through the skin to allow drainage. You will be limited to sponge baths until the drains and dressings are removed. After that you may take showers but no baths for 2 weeks. You may experience pain, burning, and numbness for a few days. Take pain medicine as prescribed by your doctor. You may notice a certain amount of bruising and swelling. The bruising will disappear gradually over 1 to 2 weeks. Some swelling may last for up to 6 months. If you have skin sutures they will be removed in 7 to 10 days. You should be able to be up and moving around the house the day after surgery but avoid any strenuous activity for about 1

Thalassemia (thal-uh-SEE-me-uh) is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.

Many mothers notice engorgement, or over-filled breasts, at some point or the other while they are breast-feeding their baby and it is especially common to experience when your baby is first born and you are just starting to make milk. So for the first couple of days you make colostrum and then 2-5 days later your milk comes in. And sometimes it comes in with a vengeance and all of the sudden you feel really full and it can be painful and very uncomfortable. Normally your milk supply will even out and start to work well with your babys demand, so it is kind of a supply and demand type of function, but until then, if you feel engorgement, there are a few things you can do to relieve it. If you are nursing your baby on demand this will usually help to self-regulate and most young babies want to eat every 2-3 hours and sometimes even every hour. So, basically, the more often your breasts are emptied the more relief you will feel. But on the same hand, the more you nurse the more milk your body will probably produce. This is why it is good to go off of your babys cues because then you will make what your baby needs and hopefully not much more. But if you are making more than your baby needs and you find that you are still full after feedings you will probably have to either manually express some milk or pump it off, so have a good pump available in case you need to, and if you don't, you can manually express the milk by gently massaging from the armpit down towards the nipple. And you can also try using heat prior to nursing your baby or pumping milk off and this will also help to relax things and help you to get the milk out. Take a warm shower and then feed your baby or use a warm compress.

Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy the entire larynx is removed and in a partial laryngectomy only a portion is taken out. The laryngectomee breathes through an opening in the neck known as a stoma.

If you need heart bypass surgery, the procedure is pretty similar. A surgeon takes blood vessels from another part of your body to go around, or bypass, a blocked artery. The result is that more blood and oxygen can flow to your heart again. ... Bypass surgery is also known as coronary artery bypass grafting (CABG).Dec 12, 2015

Ten percent of all pregnancies are complicated by hypertension. Eclampsia and preeclampsia account for about half of these cases worldwide, and these conditions have been recognized and described for years despite the general lack of understanding of the disease. [1] In the fifth century, Hippocrates noted that headaches, convulsions, and drowsiness were ominous signs associated with pregnancy. In 1619, Varandaeus coined the term eclampsia in a treatise on gynecology. [2, 3]

Initial treatment of a deviated septum may be directed at managing the symptoms of the tissues lining the nose, which may then contribute to symptoms of nasal obstruction and drainage. Your doctor may prescribe: Decongestants. Decongestants are medications that reduce nasal tissue swelling, helping to keep the airways on both sides of your nose open. Decongestants are available as a pill or as a nasal spray. Use nasal sprays with caution, however. Frequent and continued use can create dependency and cause symptoms to be worse (rebound) after you stop using them. Decongestants have a stimulant effect and may cause you to be jittery as well as elevate your blood pressure and heart rate. Antihistamines. Antihistamines are medications that help prevent allergy symptoms, including obstruction and runny nose. They can also sometimes help nonallergic conditions such as those occurring with a cold. Some antihistamines cause drowsiness and can affect your ability to perform tasks that require physical coordination, such as driving. Nasal steroid sprays. Prescription nasal corticosteroid sprays can reduce inflammation in your nasal passage and help with obstruction or drainage. It usually takes from one to three weeks for steroid sprays to reach their maximal effect, so it is important to follow your doctor's directions in using them. Medications only treat the swollen mucus membranes and won't correct a deviated septum.
