Methotrexate for Rheumatoid Arthritis
Methotrexate for Rheumatoid Arthritis samer kareem 1,698 Views • 2 years ago

Methotrexate works by reducing the function of the cells that are causing inflammation in the joint tissues. "Its use can reduce inflammation and therefore should help relieve pain and protect from joint damage," notes Sean A. Whelton, MD, a rheumatologist and associate professor of medicine at MedStar Georgetown University Hospital in Washington, D.C. Less inflammation in the joints should mean less joint pain and less joint swelling. You should also feel less fatigue and less morning stiffness.

If you have gestational diabetes, your baby may be at increased risk of: Excessive birth weight. Extra glucose in your bloodstream crosses the placenta, which triggers your baby's pancreas to make extra insulin. This can cause your baby to grow too large (macrosomia).

The development of the gastrointestinal tract
The development of the gastrointestinal tract samer kareem 2,524 Views • 2 years ago

The gastrointestinal tract (GIT) arises initially during the process of gastrulation from the endoderm of the trilaminar embryo (week 3) and extends from the buccopharyngeal membrane to the cloacal membrane. The tract and associated organs later have contributions from all the germ cell layers. During the 4th week three distinct regions (fore-, mid- and hind-gut) extend the length of the embryo and will contribute different components of the GIT. The large mid-gut is generated by lateral embryonic folding which "pinches off" a pocket of the yolk sac, the 2 compartments continue to communicate through the vitelline duct. The oral cavity (mouth) is formed following breakdown of the buccopharyngeal membrane (oropharyngeal or oral membrane) and contributed to mainly by the pharynx lying within the pharyngeal arches (More? Head Development). Loss of buccopharyngeal membrane opens the tract to amniotic fluid through the remainder of development, and during the fetal period is actively swallowed.

What could cause a blockage in the stomach? Mechanical causes of intestinal obstruction may include: Adhesions or scar tissue that forms after surgery. Foreign bodies (objects that are swallowed and block the intestines) Gallstones (rare) Hernias. Impacted stool. Intussusception (telescoping of one segment of bowel into another) Tumors blocking the intestines. Less common radiologic signs are seen in specific circumstances. Most closed-loop obstructions (75%) are caused by adhesions. A closed-loop obstruction occurs when a loop of bowel is not decompressed by the caudal passage of gas and fluid.

Swallowing Semen, Is that dangerous?
Swallowing Semen, Is that dangerous? samer kareem 20,292 Views • 2 years ago

Ejaculating into a partner’s mouth is a common practice during oral sex/fellatio. In a safe situation (where there is no danger of catching an STD), the semen-receiving partner may choose to spit the semen out, or to swallow it. Before you engage in fellatio, I’d recommend that you and your partner both get tested for sexually transmitted infections (STIs). If not, please use barriers for oral sex and abstaining from making contact with ejaculate. Semen is mostly water, but also contains amino acids and protein, sugars such as fructose and glucose, minerals such as zinc and calcium, vitamin C, and a few other nutrients. Sperm cells themselves make up less than one percent of semen. Semen is edible, and if swallowed, will travel down the esophagus and into the stomach, where it will be digested in the same way that food is. You can never get pregnant by swallowing semen. Some people accept the taste of semen, but others complain that swallowing semen can give them an upset stomach. In rare cases, you may have an allergy to the proteins found in semen. What does It Taste Like? The taste of semen varies. Bitter, sweet, metallic. So, one may expect to find the taste of semen anywhere from enjoyable to tasteless to disgusting. But there is a way of controlling the taste of semen, which is through diet. Keep track of the diet, and communicate with the partner about when it tastes better or worse.

Bowel Obstruction
Bowel Obstruction samer kareem 1,867 Views • 2 years ago

A bowel obstruction happens when either your small or large intestine is partly or completely blocked. The blockage prevents food, fluids, and gas from moving through the intestines in the normal way. The blockage may cause severe pain that comes and goes. This topic covers a blockage caused by tumors, scar tissue, or twisting or narrowing of the intestines. It does not cover ileus, which most commonly happens after surgery on the belly (abdominal surgery). What causes a bowel obstruction? Tumors, scar tissue (adhesions), or twisting or narrowing of the intestines can cause a bowel obstruction. These are called mechanical obstructions . In the small intestine, scar tissue is most often the cause. Other causes include hernias and Crohn's disease, which can twist or narrow the intestine, and tumors, which can block the intestine. A blockage also can happen if one part of the intestine folds like a telescope into another part, which is called intussusception.

Niemann-Pick Disease
Niemann-Pick Disease samer kareem 1,597 Views • 2 years ago

Niemann-Pick disease is a condition that affects many body systems. It has a wide range of symptoms that vary in severity. Niemann-Pick disease is divided into four main types: type A, type B, type C1, and type C2. These types are classified on the basis of genetic cause and the signs and symptoms of the condition. Infants with Niemann-Pick disease type A usually develop an enlarged liver and spleen (hepatosplenomegaly) by age 3 months and fail to gain weight and grow at the expected rate (failure to thrive). The affected children develop normally until around age 1 year when they experience a progressive loss of mental abilities and movement (psychomotor regression). Children with Niemann-Pick disease type A also develop widespread lung damage (interstitial lung disease) that can cause recurrent lung infections and eventually lead to respiratory failure. All affected children have an eye abnormality called a cherry-red spot, which can be identified with an eye examination. Children with Niemann-Pick disease type A generally do not survive past early childhood.

Among common cancers, pancreatic cancer has one of the poorest prognoses. Because pancreatic cancer often grows and spreads long before it causes any symptoms, only about 6% of patients are still alive five years after diagnosis. For some pancreatic patients, however, a complex surgery known as the Whipple procedure may extend life and could be a potential cure. Those who undergo a successful Whipple procedure may have a five-year survival rate of up to 25%.

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

Medial medullary syndrome, also known as Dejerine syndrome, represents less than 1% of brainstem stroke syndromes. Thrombotic or embolic occlusion of small perforating branches from vertebral or proximal basilar artery supplying the medial aspect of medulla oblongata cause this rare syndrome. It is characterized by contralateral hemiplegia/hemiparesis as well as hemisensory loss with ipsilateral hypoglossal palsy (ipsilateral tongue weakness and atrophy) from involvement of CN XII nucleus. Other manifestations e.g. vertigo, nausea, ipsilateral limb ataxia are also reported.
