Elizabeth H. Stephens, M.D., Ph.D., is an Assistant Professor of Surgery in Cardiovascular Surgery specializing in congenital cardiac surgery. She received her medical degree from Baylor College of Medicine and Ph.D in Bioengineering from Rice University focusing on tissue engineering heart valves. Her adult cardiothoracic training was completed at Columbia University and congenital training at Lurie Children's Hospital in Chicago. Her clinical areas of expertise include the treatment of:
• Neonates, infants, and children with complex congenital heart disease
• Adult patients with congenital heart disease, including patients previously repaired
• Valve disease, including Ebstein's anomaly
• Pediatric patients with heart failure, including mechanical circulatory support and heart transplantation
• Patients with vascular rings and tracheal stenosis
In addition to her clinical areas of expertise, Dr. Stephens is active in outcomes research relative to congenital heart disease and is extensively published on various cardiac surgery conditions. She has a particular interest in education, including serving on national committees and mentoring trainees of all levels.
When taking oral corticosteroids longer term, you may experience: Clouding of the lens in one or both eyes (cataracts) High blood sugar, which can trigger or worsen diabetes. Increased risk of infections. Thinning bones (osteoporosis) and fractures. Suppressed adrenal gland hormone production
The vast majority of glucocorticoid activity in most mammals is from cortisol, also known as hydrocortisone. Corticosterone, the major glucocorticoid in rodents, is another glucocorticoid. Cortisol binds to the glucocorticoid receptor in the cytoplasm and the hormone-receptor complex is then translocated into the nucleus, where it binds to its DNA response element and modulates transcription from a battery of genes, leading to changes in the cell's phenotype. Only about 10% of circulating cortisol is free. The remaining majority circulates bound to plasma proteins, particularly corticosteroid-binding globulin (transcortin). This protein binding likely decreases the metabolic clearance rate of glucocorticoids and, because the bound steroid is not biologically active, tends to act as a buffer and blunt wild fluctuations in cortisol concentration.

CPAP, or continuous positive airway pressure, is a treatment that uses mild air pressure to keep the airways open. CPAP typically is used by people who have breathing problems, such as sleep apnea. CPAP also may be used to treat preterm infants whose lungs have not fully developed.
They might not sound very life threatening, but a blood clot that develops in the deep veins of your leg, if left untreated and unable to dissolve of its own volition, may detach and travel to your lungs, causing a pulmonary embolism (or PE). In most cases, a leg blood clot will form due to lengthy periods of travel, for example if you remain immobile in cramped spaces—such as an airplane or bus—with few opportunities to stretch your legs or get up and walk around. Here are ten signs that you may have a dangerous blood clot in your leg
Your kidneys are two bean-shaped organs that lie just below your rib cage, on each side of your spine. They remove waste from your body, level out your blood pressure, and keep your bones strong. They also ensure that you have the right amount of chemicals, like potassium and sodium (salt), in your blood. Finally, they make the hormone that causes your body to create red blood cells.
The superior sagittal sinus (also known as the superior longitudinal sinus), within the human head, is an unpaired area along the attached margin of falx cerebri. It allows blood to drain from the lateral aspects of anterior cerebral hemispheres to the confluence of sinuses.
-Korsakoff's syndrome is a common and preventable sequel of Wernicke's encephalopathy. Thiamine, if given during the stage of Wernicke's encephalopathy, can prevent the onset of Korsakoff's psychosis. The administration of glucose prior to thiamine can precipitate Korsakoff's syndrome, as seen in this case. In such patients, brain MRI frequently shows abnormal enhancement of the mammillary bodies & thallamus
Stapling is used to treat prolapsed hemorrhoids. A surgical staple fixes the prolapsed hemorrhoid back into place inside your rectum and cuts off the blood supply so that the tissue will shrink and be reabsorbed. Stapling recovery takes less time and is less painful than recovery from a hemorrhoidectomy.
The patient has spasticity in the lower extremities greater than the upper extremities. The hips and knees are flexed and adducted with the ankles extended and internally rotated. When the patient walks both lower extremities are circumducted and the upper extremities are held in a mid or low guard position. This type of gait is usually seen with bilateral periventricular lesions. The legs are more affected than the arms because the corticospinal tract axons that are going to the legs are closest to the ventricles.
Haemorrhoids is one of the most common problems seen in surgical OPD. Open haemorrhoidectomy has remained the gold standard for a long time with a high post-operative morbidity. The quest for a better understanding of the pathology of haemorrhoids resulted in the evolvement of stapler haemorrhoidopexy. Our aim is to study the efficacy of stapler haemorrhoidopexy with regards to role of immediate post-operative morbidity. A prospective study of 50 patients (n = 50) with the second- and third-degree symptomatic haemorrhoids was done. The mean age of the patients was 44.1 years. Fourteen patients had co-morbid conditions. The average duration of the operation was 29 min. Patients with the second-degree haemorrhoids had higher rate of complication. The complication rate was 32%. Three patients had urinary retention. Two patients had minor bleeding, and one patient experienced transient discharge. The mean analgesic requirement was 2.4 tramadol, 50 mg injections. Ten patients had significant post-operative pain. Average length of hospital stay was 2.7 days. There were no symptomatic recurrences till date.
