The preferred route of access for temporary transvenous pacing is the internal jugular vein followed by subclavian and femoral veins. However, all the major venous access sites (internal and external jugular, subclavian, brachial, femoral) have been used and each is associated with particular problems.
Ca2+ binds with the membrane of the synaptic vesicles, which causes the vesicles to break and release the neurotransmitter into the synaptic cleft. After the neurotransmitters are released, they diffuse across the synaptic cleft and interact with receptors on the postsynaptic membrane. When the action potential reaches the presynaptic terminal, it provokes the release of a small quantity of neurotransmitter molecules, which bind to chemical receptor molecules located in the membrane of another neuron, the postsynaptic neuron, on the opposite side of the synaptic cleft.
Ascites, the collection of fluid within the peritoneal space is caused due to a variety of causes including cirrhosis, cardiac causes, sinusoidal obstruction syndrome, tubercular peritonitis and pancreatitis, amongst others. Most commonly, the cause of ascots may be cirrhosis , which in turn, is most frequently causes by alcohol use, hepatitis C and non-alcoholic steatohepatitis. At the heart of the ascitic fluid analysis is the serum albumin ascitic gradient, the differential diagnosis of which has been discussed in detail in this presentation. Both low SAAG and high SAAG ascites have been dealt with in some depth, with a brief overview of the management of these conditions
Cardiac tamponade Email this page to a friend Print Facebook Twitter Bookmark & Share Cardiac tamponade is pressure on the heart that occurs when blood or fluid builds up in the space between the heart muscle (myocardium) and the outer covering sac of the heart (pericardium). Causes In this condition, blood or fluid collects in the pericardium, the sac surrounding the heart. This prevents the heart ventricles from expanding fully. The excess pressure from the fluid prevents the heart from working properly. As a result, the body does not get enough blood. Cardiac tamponade can occur due to: Dissecting aortic aneurysm (thoracic) End-stage lung cancer Heart attack (acute MI) Heart surgery Pericarditis caused by bacterial or viral infections Wounds to the heart
Acute kidney injury is common entity in medical practice. The present definition is based on a serum creatinine rise of more 0.3 mg/dl in 48 hours or less, a 50% increase from the baseline over a period of 07 days or a urine output of less than 0.5 ml/kg/hour for more than 06 hours. The main causes of acute kidney injury may be classified into pre renal, intrinsic or post renal causes. Rapid diagnosis and prompt treatment is essential to prevent mortality or morbidity. This presentation discusses in detail the causes of all three mechanisms, pre-renal, post renal and intrinsic.
It used to be when a woman needed a hysterectomy she could expect full abdominal surgery with a long recovery time. Dr. Melissa Lee uses less invasive methods that can cut the patients downtime in half.
"We were trained in more laparoscopic and minimally invasive cases so of course that's what I'm more comfortable with doing right now."
She sees a new generation of patients opting for laparoscopic surgery.
"Laparoscopy is the use of small cameras with small incisions and instruments that are guided by the hand, and you're able to see directly into the abdomen without actually fully opening the abdomen," says Dr. Lee, an obstetrician-gynecologist with Lee Memorial Health System.
Nowadays, even a large mass or uterus can be removed using the slender tools.
"There are multiple different laparoscopic instruments that you can use. Whether they're blunt dissections or just dissectors that hold and retract back or actual scissors or cutting instruments, there are multiple different options," says Dr. Lee.
While a standard abdominal hysterectomy requires a four to eight inch incision, the laparoscope needs only a quarter to half inch. It's enough to make a big difference in terms of recovery.
"They're able to get up and move around faster. They're able to recover faster, their pain level and their need for pain medicine is much lower," says Dr. Lee.
The laparoscopic procedure also cuts down on scarring and more importantly, shortens the hospital stay. The trend now is home within 24 hours.
"Where the patient is done early in the morning, they're doing well they're tolerating oral intake they're able to getup and move around. And those patients a lot of times will feel comfortable to go home that same nigh after a major surgery," says Dr. Lee.
New studies show women who've had a laparoscopic hysterectomy viewed their quality of life as better than those who had an open abdominal procedure, making this a good option for the right patient.

Barrett's esophagus is a complication of chronic (long lasting) and usually severe gastrointestinal reflux disease (GERD), but occurs in only a small percentage of patients with GERD. Criteria are needed for screening patients with GERD for Barrett's esophagus. Until validated criteria are available, it seems reasonable to do screening endoscopies in GERD patients who cannot be taken off acid suppression therapy after two to three years. The diagnosis of Barrett's esophagus rests upon seeing (at endoscopy) a pink esophageal lining that extends a short distance (usually less than 2.5 inches) up the esophagus from the gastroesophageal junction and finding intestinal type cells (goblet cells) on biopsy of the lining. There is a small but definite increased risk of cancer of the esophagus (adenocarcinoma) in patients with Barrett's esophagus.
Erectile dysfunction (ED) is the inability to get or keep an erection firm enough for sexual function. It’s a common sexual problem, affecting as many as 30 million men in the United States. Most cases of ED have a physical cause, such as heart disease, diabetes, and obesity. Lifestyle choices like smoking and drinking excessive amounts of alcohol can also lead to ED. But for some men, psychological issues are the root of the problem.
