By 5 weeks' gestational age, the wolffian (ie, mesonephric) and the müllerian (ie, paramesonephric) ducts have formed from intermediate mesoderm. In the absence of testosterone and müllerian inhibitory substance, the mesonephric ducts regress and the paramesonephric ducts continue to form the female reproductive structures with fusion of the distal portions of the paramesonephric ducts to give rise to the uterine fundus, the cervix, and the upper vagina. These developmental changes are genetically controlled in large part by a series of complex transcriptional signaling pathways including Wnt signaling, Hox genes, and many others. In a female fetus, the wolffian duct disappears except for nonfunctional vestiges. The müllerian duct is lined by a columnar epithelium. This includes the entire cervix and upper vagina to the vaginal plate (ie, sinovaginal bulb). Through a process of squamous metaplasia, the vagina and a variable portion of the ectocervix become covered with squamous epithelium. This process is complete by the fifth month of pregnancy.

Sclerotherapy is a medical procedure used to eliminate varicose veins and spider veins. Sclerotherapy involves an injection of a solution (generally a salt solution) directly into the vein. The solution irritates the lining of the blood vessel, causing it to collapse and stick together and the blood to clot.

What Is an Appendectomy? An appendectomy is the surgical removal of the appendix. It’s a common emergency surgery that’s performed to treat appendicitis, an inflammatory condition of the appendix. The appendix is a small, tube-shaped pouch attached to your large intestine. It’s located in the lower right side of your abdomen. The exact purpose of the appendix isn’t known. However, it’s believed that it may help us recover from diarrhea, inflammation, and infections of the small and large intestines. These may sound like important functions, but the body can still function properly without an appendix. When the appendix becomes inflamed and swollen, bacteria can quickly multiply inside the organ and lead to the formation of pus. This buildup of bacteria and pus can cause pain around the belly button that spreads to the lower right section of the abdomen. Walking or coughing can make the pain worse. You may also experience nausea, vomiting, and diarrhea. It’s important to seek treatment right away if you’re having symptoms of appendicitis. When the condition goes untreated, the appendix can burst (perforated appendix) and release bacteria and other harmful substances into the abdominal cavity. This can be life-threatening, and will lead to a longer hospital stay. Appendectomy is the standard treatment for appendicitis. It’s crucial to remove the appendix right away, before the appendix can rupture. Once an appendectomy is performed, most people recover quickly and without complications. Why Is an Appendectomy Performed? An appendectomy is often done to remove the appendix when an infection has made it inflamed and swollen. This condition is known as appendicitis. The infection may occur when the opening of the appendix becomes clogged with bacteria and stool. This causes your appendix to become swollen and inflamed. The easiest and quickest way to treat appendicitis is to remove the appendix. Your appendix could burst if appendicitis isn’t treated immediately and effectively. If the appendix ruptures, the bacteria and fecal particles within the organ can spread into your abdomen. This may lead to a serious infection called peritonitis. You can also develop an abscess if your appendix ruptures. Both are life-threatening situations that require immediate surgery. Symptoms of appendicitis include: stomach pain that starts suddenly near the belly button and spreads to the lower right side of the abdomen abdominal swelling rigid abdominal muscles constipation or diarrhea nausea vomiting loss of appetite low-grade fever Although pain from appendicitis typically occurs in the lower right side of the abdomen, pregnant women may have pain in the upper right side of the abdomen. This is because the appendix is higher during pregnancy. Go to the emergency room immediately if you believe you have appendicitis. An appendectomy needs to be performed right away to prevent complications. What Are the Risks of an Appendectomy? An appendectomy is a fairly simple and common procedure. However, there are some risks associated with the surgery, including: bleeding infection injury to nearby organs blocked bowels It’s important to note that the risks of an appendectomy are much less severe than the risks associated with untreated appendicitis. An appendectomy needs to be done immediately to prevent abscesses and peritonitis from developing. How Do I Prepare for an Appendectomy? You’ll need to avoid eating and drinking for at least eight hours before the appendectomy. It’s also important to tell your doctor about any prescription or over-the-counter medications you’re taking. Your doctor will tell you how they should be used before and after the procedure. You should also tell your doctor if you: are pregnant or believe you may be pregnant are allergic or sensitive to latex or certain medications, such as anesthesia have a history of bleeding disorders You should also arrange for a family member or friend to drive you home after the procedure. An appendectomy is often performed using general anesthesia, which can make you drowsy and unable to drive for several hours after surgery. Once you’re at the hospital, your doctor will ask you about your medical history and perform a physical examination. During the exam, your doctor will gently push against your abdomen to pinpoint the source of your abdominal pain. Your doctor may order blood tests and imaging tests if appendicitis is caught early. However, these tests may not be performed if your doctor believes an emergency appendectomy is necessary. Before the appendectomy, you’ll be hooked up to an IV so you can receive fluids and medication. You’ll likely be put under general anesthesia, which means you’ll be asleep during surgery. In some cases, you’ll be given local anesthesia instead. A local anesthetic numbs the area, so even though you’ll be awake during the surgery, you won’t feel any pain. How Is an Appendectomy Performed? There are two types of appendectomy: open and laparoscopic. The type of surgery your doctor chooses depends on several factors, including the severity of your appendicitis and your medical history. Open Appendectomy During an open appendectomy, a surgeon makes one incision in the lower right side of your abdomen. Your appendix is removed and the wound is closed with stiches. This procedure allows your doctor to clean the abdominal cavity if your appendix has burst. Your doctor may choose an open appendectomy if your appendix has ruptured and the infection has spread to other organs. It’s also the preferred option for people who have had abdominal surgery in the past. Laparoscopic Appendectomy During a laparoscopic appendectomy, a surgeon accesses the appendix through a few small incisions in your abdomen. A small, narrow tube called a cannula will then be inserted. The cannula is used to inflate your abdomen with carbon dioxide gas. This gas allows the surgeon to see your appendix more clearly. Once the abdomen is inflated, an instrument called a laparoscope will be inserted through the incision. The laparoscope is a long, thin tube with a high-intensity light and a high-resolution camera at the front. The camera will display the images on a screen, allowing the surgeon to see inside your abdomen and guide the instruments. When the appendix is found, it will be tied off with stiches and removed. The small incisions are then cleaned, closed, and dressed. Laparoscopic surgery is usually the best option for older adults and people who are overweight. It has fewer risks than an open appendectomy procedure, and generally has a shorter recovery time. What Happens After an Appendectomy? When the appendectomy is over, you’ll be observed for several hours before you’re released from the hospital. Your vital signs, such your breathing and heart rate, will be monitored closely. Hospital staff will also check for any adverse reactions to the anesthesia or the procedure. The timing of your release will depend on: your overall physical condition the type of appendectomy performed your body’s reaction to the surgery In some cases, you may have to remain in the hospital overnight. You may be able to go home the same day as the surgery if your appendicitis wasn’t severe. A family member or friend will need to drive you home if you received general anesthesia. The effects of general anesthesia usually take several hours to wear off, so it can be unsafe to drive after the procedure. In the days following the appendectomy, you may feel moderate pain in the areas where incisions were made. Any pain or discomfort should improve within a few days. Your doctor may prescribe medication to relieve the pain. They might also prescribe antibiotics to prevent an infection after surgery. You can further reduce your risk for infection by keeping the incisions clean. You should also watch for signs of infection, which include: redness and swelling around the incision fever above 101°F chills vomiting loss of appetite stomach cramps diarrhea or constipation that lasts for more than two days Although there’s a small risk of infection, most people recover from appendicitis and an appendectomy with little difficulty. Full recovery from an appendectomy takes about four to six weeks. During this time, your doctor will probably recommend that you limit physical activity so your body can heal. You’ll need to attend a follow-up appointment with your doctor within two to three weeks after the appendectomy.

This video, Rheumatoid arthritis is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition also can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels. An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well. While new types of medications have improved treatment options dramatically, severe rheumatoid arthritis can still cause physical disabilities.

Anybody can and anybody should learn how to perform CPR (Cardiopulmonary resuscitation): According to the American Heart Association, a stunning 70% of Americans don’t know how what to do if somebody is experiencing a cardiac emergency because they don’t know how to administer CPR or they forgot the exact technique. This is especially alarming since almost 90% of cardiac arrests occur at home — where patients depend on the immediate respiratory care response of their family members. In brief, knowing how to perform CPR can save the life of a loved one someday.

This video: Claudication is pain caused by too little blood flow, usually during exercise. Sometimes called intermittent claudication, this condition generally affects the blood vessels in the legs, but claudication can affect the arms, too. At first, you'll probably notice the pain only when you're exercising, but as claudication worsens, the pain may affect you even when you're at rest. Although it's sometimes considered a disease, claudication is technically a symptom of a disease. Most often, claudication is a symptom of peripheral artery disease, a potentially serious but treatable circulation problem in which the vessels that supply blood flow to your legs or arms are narrowed. Fortunately, with treatment, you may be able to maintain an active lifestyle without pain.
