Our specialists treat conditions that are recurrent and hard to treat. Simply put, TPIAT a procedure that lets surgeons remove the pancreas, take out islet cells – the cells in the pancreas that make insulin – and put those islet cells into the liver. Patients then take pancreatic enzymes to help them digest food.

Some of the cardiac and thoracic conditions treated by Emory cardiac surgeons include mitral valve repair and replacement, atrial septal defect repair, atrial myxoma and thrombi, coronary bypass (LIMA to LAD), mediastinal mass excision, thymectomy, epicardial lead placement and pericardial window.

Chordoid meningioma
Chordoid meningioma samer kareem 14,364 Views • 2 years ago

Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.

Hepatitis B Symptoms and Treatment
Hepatitis B Symptoms and Treatment samer kareem 1,484 Views • 2 years ago

Hepatitis B is a liver infection caused by the Hepatitis B virus (HBV). Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the Hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection. Risk for chronic infection is related to age at infection: approximately 90% of infected infants become chronically infected, compared with 2%–6% of adults. Chronic Hepatitis B can lead to serious health issues, like cirrhosis or liver cancer. The best way to prevent Hepatitis B is by getting vaccinated.

Hemophagocytic lymphohistiocytosis is a rare but life threatening condition characterised by activation of macrophages which result in phagocytosis of RBCs and cytokine mediated tissue damage. This presentation aims to discuss the genetic basis, clinical features, diagnostic criteria and management options in this serious condition. The management options in HLH include Etoposide, Dexamethasone, Cyclosorine, Tacrolimus, Alemtuzumab and stem cell transplant.

Sinus infection
Sinus infection samer kareem 14,838 Views • 2 years ago

You're sneezing, coughing, and all stuffed up. It sounds and feels like a cold, alright. But as time goes on, you start to wonder. Is it turning into a sinus infection? They've got some things in common, but there are ways to tell them apart. The right ID lets your doctor get you the best treatment. What Is a Common Cold? It's an infection caused by a virus, a tiny living thing. You can't miss the symptoms: Nasal congestion Runny nose Post-nasal drip (drop-by-drop release of fluid from your nose into the back of the throat) Headache Fatigue You may also get a cough and a mild fever. The symptoms usually build, peak, and slowly disappear. Some medications can ease symptoms. For example, decongestants may decrease drainage and open the nasal passages. Pain relievers may help with fever and headache. Cough medicine may help, as well. Colds typically last from a few days to about a week or longer. Sometimes, a cold may cause swelling in the sinuses, hollow spaces in your skull that are connected to each other. The swelling can prevent the flow of mucus.

Lumbar Fusion of L5-S1 Surgery
Lumbar Fusion of L5-S1 Surgery samer kareem 3,955 Views • 2 years ago

At each level of the spine, there is a disc space in the front and paired facet joints in the back. Working together, these structures define a motion segment (Fig. 1A). Back pain may re­sult when injury or degenerative changes allow abnormal movement of the vertebrae to rub against one another, known as an unstable motion segment (Fig. 1B). Two vertebrae need to be fused to stop the motion at one segment. For example, an L4-L5 fusion is a one-level spinal fusion (Fig. 1C). A two-level fusion joins three vertebrae together and so on.

Basics of Multiple Endocrine Neoplasia
Basics of Multiple Endocrine Neoplasia samer kareem 5,094 Views • 2 years ago

Multiple endocrine neoplasia is a group of disorders that affect the body's network of hormone-producing glands (the endocrine system). Hormones are chemical messengers that travel through the bloodstream and regulate the function of cells and tissues throughout the body. Multiple endocrine neoplasia typically involves tumors (neoplasia) in at least two endocrine glands; tumors can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). If the tumors become cancerous, the condition can be life-threatening.

Low Thyroid - Could It Be A T3 Problem?
Low Thyroid - Could It Be A T3 Problem? samer kareem 5,794 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.

Cortisol and Glucocorticoids
Cortisol and Glucocorticoids samer kareem 3,644 Views • 2 years ago

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.
