Vaginal ChildBirth after Cesarean Section (C-Section)
Vaginal ChildBirth after Cesarean Section (C-Section) Surgeon 123,474 Views • 3 years ago

At one time, women who had delivered by cesarean section in the past would usually have another cesarean section for any future pregnancies. The rationale was that if allowed to labor, many of these women with a scar in their uterus would rupture the uterus along the weakness of the old scar. Over time, a number of observations have become apparent: Most women with a previous cesarean section can labor and deliver vaginally without rupturing their uterus. Some women who try this will, in fact, rupture their uterus. When the uterus ruptures, the rupture may have consequences ranging from near trivial to disastrous. It can be very difficult to diagnose a uterine rupture prior to observing fetal effects (eg, bradycardia). Once fetal effects are demonstrated, even a very fast reaction and nearly immediate delivery may not lead to a good outcome. The more cesarean sections the patient has, the greater the risk of subsequent rupture during labor. The greatest risk occurs following a “classical” cesarean section (in which the uterine incision extends up into the fundus.) The least risk of rupture is among women who had a low cervical transverse incision. Low vertical incisions probably increase the risk of rupture some, but usually not as much as a classical incision. Many studies have found the use of oxytocin to be associated with an increased risk of rupture, either because of the oxytocin itself, or perhaps because of the clinical circumstances under which it would be contemplated. Pain medication, including epidural anesthetic, has not resulted greater adverse outcome because of the theoretical risk of decreasing the attendant’s ability to detect rupture early. The greatest risk of rupture occurs during labor, but some of the ruptures occur prior to the onset of labor. This is particularly true of the classical incisions. Overall successful vaginal delivery rates following previous cesarean section are in the neighborhood of 70 This means that about 30of women undergoing a vaginal trial of labor will end up requiring a cesarean section. Those who undergo cesarean section (failed VBAC) after a lengthy labor will frequently have a longer recovery and greater risk of infection than had they undergone a scheduled cesarean section without labor. Women whose first cesarean was for failure to progress in labor are only somewhat less likely to be succesful in their quest for a VBAC than those with presumably non-recurring reasons for cesarean section. For these reasons, women with a prior cesarean section are counseled about their options for delivery with a subsequent pregnancy: Repeat Cesarean Section, or Vaginal Trial of Labor. They are usually advised of the approximate 70successful VBAC rate (modified for individual risk factors). They are counseled about the risk of uterine rupture (approximately 1in most series), and that while the majority of those ruptures do not lead to bad outcome, some of them do, including fetal brain damage and death, and maternal loss of future childbearing. They are advised of the usual surgical risks of infection, bleeding, anesthesia complications and surgical injury to adjacent structures. After counseling, many obstetricians leave the decision for a repeat cesarean or VBAC to the patient. Both approaches have risks and benefits, but they are different risks and different benefits. Fortunately, most repeat cesarean sections and most vaginal trials of labor go well, without any serious complications. For those choosing a trial of labor, close monitoring of mother and baby, with early detection of labor abnormalities and preparation for

Lipid-Lowering Agents HMG-CoA reductase inhibitors (statins) These agents inhibit the rate-limiting step in cholesterol biosynthesis by competitively inhibiting HMG-CoA reductase. Note the following: Low-density lipoprotein (LDL) reduction of 25%-60% Examples include Atorvastatin, fluvastatin, lovastatin, pitavastatin, pravastatin, rosuvastatin, simvastatin Contraindications include hypersensitivity, active liver disease, pregnancy, lactation, coadministration with strong CYP3A4 inhibitors (selected statins) Vitamin B3 Vitamin B3 inhibits very-low-density lipoprotein (VLDL) synthesis. Note the following: LDL reduction of 10% High-density lipoprotein (HDL) increase of 20% Example includes Niacin (nicotinic acid) Contraindications include hypersensitivity, liver disease, active peptic ulcer, severe hypotension, arterial bleeding Fibrates Fibrates enhance lipoprotein lipase, resulting in increased VLDL catabolism, fatty acid oxidation, and triglycerides elimination. They decrease hepatic extraction of free fatty acids. Note the following: LDL reduction of 15% Triglyceride reduction of 35% Examples include Gemfibrozil, fenofibrate, fenofibrate (micronized), fenofibric acid Contraindications include active liver disease, renal disease, primary biliary cirrhosis, gallbladder disease 2-Azetidiones These agents inhibit sterol transporter at brush border and, consequently, intestinal absorption of cholesterol. LDL reduction of 15% Example includes Ezetimibe Contraindications include hypersensitivity, coadministration with statins (if active liver disease) Bile acid sequestrants These agents lower cholesterol and LDL via bile duct sequestration. Note the following: LDL reduction of 15% Examples include Cholestyramine, colesevelam, colestipol Contraindications include biliary/bowel obstruction, serum triglycerides >300-500 mg/dL, history of hypertriglyceridemia-induced pancreatitis

A breech birth occurs when a baby is born bottom first instead of head first. Around 3-5% of pregnant women at term (37–40 weeks pregnant) will have a breech baby. Most babies in the breech position are born by a caesarean section because it is seen as safer than being born vaginally.

Eosinophilic granulomatosis with polyangiitis (EGPA)—or, as it was traditionally termed, Churg-Strauss syndrome—is a rare systemic necrotizing vasculitis that affects small-to-medium-sized vessels and is associated with severe asthma and blood and tissue eosinophilia. [1] Like granulomatosis with polyangiitis (Wegener granulomatosis), and the microscopic form of periarteritis (ie, microscopic polyangiitis), EGPA is an antineutrophil cytoplasmic antibody (ANCA)–associated vasculitide. [2, 3, 4, 5] In 1951, Churg and Strauss first described the syndrome in 13 patients who had asthma, eosinophilia, granulomatous inflammation, necrotizing systemic vasculitis, and necrotizing glomerulonephritis. [3] In 1990, the American College of Rheumatology (ACR) proposed the following six criteria for the diagnosis of Churg-Strauss syndrome [6] : Asthma (wheezing, expiratory rhonchi) Eosinophilia of more than 10% in peripheral blood Paranasal sinusitis Pulmonary infiltrates (may be transient) Histological proof of vasculitis with extravascular eosinophils Mononeuritis multiplex or polyneuropathy

Special Anoscope for Easy Purse-string Suture Application in Stapled Hemorrhoidopexy Mohamed 34,905 Views • 3 years ago

Internal hemorrhoids and loose rectal mucosa may block the exposure during the purse string suturing in stapled hemorrhooidopexy, and this may cause some complications. To retract the prolapsing rectal mucosa we modified the purse string anoscope of the PPH01 kit (Ethicon-Endosurgery, Cincinnati, O...H, USA) and produced a special anoscope. The open part of the purse string suture anoscope is covered by transparent acrylic (Orthoacryl�, Dentaurum, Pforzheim, Germany). The covering material had complete cylindrical outer and inner surfaces and was thin enough to let the anoscope easily rotate in the anal dilator and to let the 26 mm curved, round bodied needle of the 2/0 polypropilene suture move in the anoscope. A window, 3 cm long and 3-4 mm wide, was opened at the angled part of the anoscope 2 cm to the tip of the anoscope. This special anoscope was used for the purse string suture during stapled hemorrhoidopexy procedure in five patients. No postoperative complications, early or late, were encountered, and we propose that stapled hemorrhoidopexy procedure can be applied more easily by using this special anoscope.

Giant Infected Spider Bite
Giant Infected Spider Bite Scott 19,627 Views • 3 years ago

Are most spiders poisonous? The majority of the 3,000 spiders in the United States aren’t poisonous. Even if most spiders did bite, their fangs are too small or weak to puncture human skin. Their bites may leave itchy, red wounds that heal within a week or so. The spiders that do manage to bite through our skin and insert toxic venom can cause serious health complications. Read on to learn what spider bites look like, what spider varieties leave certain bites, and how to treat spider bites. What do spider bites look like? Identifying a spider bite is easier if you saw the spider that bit you, but it’s possible that you won’t notice the wound until hours later. Look for things like: swelling a red welt skin damage any troubling symptoms that accompany the bite Other possible symptoms that may accompany a spider bite include: itching or rash pain around the area of the bite muscle pain or cramping blister that’s red or purple in color sweating difficulty breathing headache nausea and vomiting fever chills anxiety or restlessness rashes swollen lymph glands high blood pressure Spider bites often take longer to heal than other insect bites, and they may affect skin tissues. It’s important to keep the bite clean to reduce the risk of infection. How to treat a spider bite at home In some cases, you can treat spider bites at home. For nonvenomous spider bites, follow these steps: Apply an ice pack on and off the bite for 10 minutes at a time. Elevate the area to reduce swelling. Take an antihistamine, such as diphenhydramine (Benadryl), to help with itching. Clean the area with soap and water to prevent infection. Apply antibiotic ointment to the area if blisters develop. Seek medical attention if you’re showing symptoms of a spider bite or if the symptoms don’t go away over time. Always seek medical attention if you suspect you’ve been bitten by one of the following species: brown recluse black widow hobo spider tarantula Brazilian wandering spider

Hypertension - Antihypertensive Medications
Hypertension - Antihypertensive Medications samer kareem 3,502 Views • 3 years ago

Although drug treatment of hypertension is associated with improved survival and decreased vascular complications, drug compliance is a major problem in the control of hypertension. All antihypertensive medications are associated with side effects; thus, it is a physician's responsibility to explain to each patient the side effects of the drugs he prescribes to treat hypertension, and to instill in the patient a sense of necessity for the treatment of hypertension. The choice of antihypertensive drug should be made based on each patient's lifestyle, overall health and ability to tolerate the drug. Ideally, the antihypertensive regimen should be simple, effective, convenient to take and have very few side effects.
