Renal Artery Stenosis
Renal Artery Stenosis samer kareem 4,445 Views • 2 years ago

Renal artery stenosis is a narrowing of arteries that carry blood to one or both of the kidneys. Most often seen in older people with atherosclerosis (hardening of the arteries), renal artery stenosis can worsen over time and often leads to hypertension (high blood pressure) and kidney damage.

Massive PE causing hemodynamic instability (shock and/or low blood pressure, defined as a systolic blood pressure <90 mmHg or a pressure drop of 40 mmHg for >15 min if not caused by new-onset arrhythmia, hypovolemia or sepsis) is an indication for thrombolysis, the enzymatic destruction of the clot with medication.

Pain in the affected bone is the most common complaint of patients with bone cancer. At first, the pain is not constant. It may be worse at night or when the bone is used (for example, leg pain when walking). As the cancer grows, the pain will be there all the time. The pain increases with activity and the person might limp if a leg is involved.

Fungal infections in bone marrow transplant patients. PURPOSE OF REVIEW: Invasive fungal infections have become the leading infectious cause of death in recipients of hematopoietic cell transplantation. Several factors have led to a renaissance in the study of invasive fungal infections.

They were victims of caisson disease. This condition, also known as the bends or decompression sickness, is caused by the formation of gas bubbles in the body. Human body tissues contain small amounts of the gases present in the air.

Signs and symptoms of this condition typically appear around the age of 3 or 4 months, when babies start to sleep through the night and do not eat as frequently as newborns. Affected infants may have low blood sugar (hypoglycemia), which can lead to seizures. They can also have a buildup of lactic acid in the body (lactic acidosis), high blood levels of a waste product called uric acid (hyperuricemia), and excess amounts of fats in the blood (hyperlipidemia). As they get older, children with GSDI have thin arms and legs and short stature. An enlarged liver may give the appearance of a protruding abdomen. The kidneys may also be enlarged. Affected individuals may also have diarrhea and deposits of cholesterol in the skin (xanthomas).

Scoliosis
Scoliosis samer kareem 18,798 Views • 2 years ago

If you look at someone’s back, you’ll see that the spine runs straight down the middle. When a person has scoliosis, their backbone curves to the side. The angle of the curve may be small, large or somewhere in between. But anything that measures more than 10 degrees is considered scoliosis. Doctors may use the letters “C” and “S” to describe the curve of the backbone. You probably don’t look directly at too many spines, but what you might notice about someone with scoliosis is the way they stand. They may lean a little or have shoulders or hips that look uneven. What Causes Scoliosis? In as many as 80% of cases, doctors don’t find the exact reason for a curved spine. Scoliosis without a known cause is what doctors call “idiopathic.” Some kinds of scoliosis do have clear causes. Doctors divide those curves into two types -- structural and nonstructural. In nonstructural scoliosis, the spine works normally, but looks curved. Why does this happen? There are a number of reasons, such as one leg’s being longer than the other, muscle spasms, and inflammations like appendicitis. When these problems are treated, this type of scoliosis often goes away.

Low Thyroid - Could It Be A T3 Problem?
Low Thyroid - Could It Be A T3 Problem? samer kareem 5,781 Views • 2 years ago

NTIS refers to a syndrome found in seriously ill or starving patients with low fT3, usually elevated RT3, normal or low TSH, and if prolonged, low fT4. It is found in a high proportion of patients in the ICU setting, and correlates with a poor prognosis if TT4 is <4ug/dl. The patho-physiology includes suppression of TRH release, reducedT3 and T4 turnover, reduction in liver generation of T3, increased formation of RT3, and tissue specific down-regulation of deiodinases, transporters, and TH receptors. Although long debated, tissue TH levels are definitely reduced, and tissue hypothyroidism is presumably present. This is often not clinically evident because of the brief duration, and reduced but not absent tissue levels of TH. Although recognized for nearly 4 decades, interpretation of the syndrome is contested, because of lack of data. Some observes, totally without data, argue that it is a protective response and should not be treated. Other observers (as in this review) present available data suggesting, but not proving, that thyroid hormone replacement is appropriate, not harmful, and may be beneficial. The best form of treatment (TRH,TSH,or T3+T4) and possible accompanying treatments (GHRH, Cortisol, nutrition, insulin) lack consensus. In this review current data are laid out for reader’s review and judgment.

Best Timing and Sexual positions to get pregnant fast
Best Timing and Sexual positions to get pregnant fast samer kareem 2,387 Views • 2 years ago

You may have heard that some positions, such as your partner on top (missionary position), are better than others for getting pregnant. In fact, there's no evidence to back these theories up. Experts just haven't done the research yet. What experts have done, though, is use scanning to show what's going on inside when you're doing the deed. The research looked at two positions: the missionary position and doggy style. (Doggy style being when you're on all fours, and your partner enters you from behind). Common sense tells us that these positions allow for deep penetration. This means that they're more likely to place sperm right next to your cervix (the opening of your uterus). The scans confirm that the tip of the penis reaches the areas between the cervix and vaginal walls in both of these positions. The missionary position allows the penis to reach the area at the front of the cervix. The rear entry position reaches the area at back of the cervix. It's amazing what some experts spend their time doing, isn't it! Other positions, such as standing up, or woman on top, may be just as good for getting sperm right next to the cervix. We just don't know yet. http://www.babycentre.co.uk/sex-for-getting-pregnant#ixzz4XKnPLbxL

Why You Got Fat
Why You Got Fat samer kareem 26,582 Views • 2 years ago

The usual reason given for people getting fat is that they eat too much and/or exercise too little. That reflects one of the basic laws of thermodynamics—I forget which one. The amount of energy you put into a system minus the energy you take out has to be stored somewhere i.e. FAT! This formulation—true though it is—does not entirely explain obesity since some people seem to eat more than fat people and exercise no more than these same fat people, and yet they are not fat! Chalking this fact up to the general perversity of the universe is not sufficient explanation. Other factors must come into play. I mention below some of the ideas thoughtful people have proposed to explain why fat people become fat:

Biliary ileus
Biliary ileus samer kareem 2,406 Views • 2 years ago

Gallstone ileus is an important, though infrequent, cause of mechanical bowel obstruction, affecting older adult patients who often have other significant medical conditions. It is caused by impaction of a gallstone in the ileum after being passed through a biliary-enteric fistula. The diagnosis is often delayed since symptoms may be intermittent and investigations fail to identify the cause of the obstruction. The mainstay of treatment is removal of the obstructing stone after resuscitating the patient. Gallstone ileus continues to be associated with relatively high rates of morbidity and mortality.

Stress ulcer

A stress ulcer is a single or multiple mucosal defect which can become complicated by upper gastrointestinal bleeding during the physiologic stress of serious illness.

Stress-related mucosal disease (SRMD) is an acute, erosive gastritis representing conditions ranging from stress-related injury to stress ulcers (1, 2). Stress-related injury is superficial mucosal damage that presents primarily as erosions, whereas stress ulcers are deep, focal mucosal damage penetrating the submucosa with high risk for gastrointestinal bleeding (2, 3). Mucosal damage has been reported to occur during the first 24 hours of hospital admission in 75% to 100% of intensive care unit (ICU) patients (4, 5). Clinically important gastrointestinal bleeding can cause hemodynamic instability and increase the need for red blood cell transfusions (1). Significant bleeding may also increase the length of stay in the ICU and mortality (1).
