Acute kidney injury: mechanism, diagnosis and management
Acute kidney injury: mechanism, diagnosis and management samer kareem 1,522 Views • 2 years ago

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.

Small cell lung cancer: diagnosis and management
Small cell lung cancer: diagnosis and management samer kareem 1,580 Views • 2 years ago

Small cell lung cancer, which occurs almost exclusively in smokers, is a malignancy characterised by rapid doubling time, high growth fraction and widespread metastasis at presentation. In this presentation, we will briefly discuss the classification of pulmonary Neuro-endocrine tumours by the World Health Organisation followed by a detailed discussion of the clinical features, lab evaluation and management of SCLC, both limited and extended stage. The frontline therapy in small cell lung cancer is etoposide and cisplatin along with thoracic radiotherapy and prophylactic cranial irradiation in patients who have a good response to therapy. Hyperfractionation of radiotherapy may provide some benefit but is also associated with increase incidence of complications. Newer agents for SCLC include Vandetanib and immunotherapy molecules, such as Iplimumab and nivolumab.

Aplastic anemia: causes, diagnosis and managment
Aplastic anemia: causes, diagnosis and managment samer kareem 1,322 Views • 2 years ago

Aplastic anemia is a hematopoietic disorder caused due to T lymphocyte mediated destruction of stem cells resulting in pancytopenia with a cellular bone marrow and normal cell cytogenetics. The causes of aplastic anaemia may be inherited or acquired. The causes and the diagnostic approach, along with spectrum of severity of this disorder is discussed in this presentation. A detailed discussion of the management options, along with pharmacological therapy and supportive therapy in these cases is also discussed. The treatment options include, in addition to a stem cell transplant, anti-thymocyte globulin, cyclosporine, methyprednisolone and eltrombopag (for patients who have failed treatment on combined modality therapy with ATG and cyclosporine)

Hyponatremia: causes, diagnosis and management
Hyponatremia: causes, diagnosis and management samer kareem 1,478 Views • 2 years ago

Hyponatremia is defined as a serum sodium of less than 135 Meq per litre and occurs in upto 22 % of hospitalised patients. The causes of hyponatremia may be understood based on the pre-existing volume status of the patient which may either be hypovolemic, euvolemic or hypervolemic hyponatremia. This presentation discusses in detail, the causes of these underlying conditions. Also mentioned are the clinical features and management options and therapeutic sodium targets in patients with hyponatremia. Drugs such as demeclocycline and vaptans (Tolvaptan, Conivaptan) are also mentioned as management options which may be used on a case to case basis. Finally, the all important targets of sodium correction over 24 hours are also mentioned, along with a practical formula for calculation of sodium deficit which is explained with an example.

A ganglion cyst is a tumor or swelling on top of a joint or the covering of a tendon (tissue that connects muscle to bone). It looks like a sac of liquid (cyst). Inside the cyst is a thick, sticky, clear, colorless, jellylike material. Depending on the size, cysts may feel firm or spongy.

Rhinoplasty enhances facial harmony and the proportions of your nose. It can also correct impaired breathing caused by structural defects in the nose. Rhinoplasty surgery can change: Nose size in relation to facial balance Nose width at the bridge or in the size and position of the nostrils Nose profile with visible humps or depressions on the bridge Nasal tip that is enlarged or bulbous, drooping, upturned or hooked Nostrils that are large, wide, or upturned Nasal asymmetry If you desire a more symmetrical nose, keep in mind that everyone’s face is asymmetric to some degree. Results may not be completely symmetric, although the goal is to create facial balance and correct proportion.

Digoxin Toxicity
Digoxin Toxicity samer kareem 1,888 Views • 2 years ago

The incidence of digitalis toxicity has declined in recent years, due to decreased use of this drug along with improved technology for monitoring of drug levels and increased awareness of drug interactions. Nevertheless, cardiac glycoside toxicity continues to be a problem in the United States because of the wide use of digoxin (a preparation of digitalis) and its narrow therapeutic window. Digitalis is a plant-derived cardiac glycoside commonly used in the treatment of chronic heart failure (CHF), atrial fibrillation, and reentrant supraventricular tachycardia.[1, 2] Digoxin is the only available preparation of digitalis in the United States. (See Etiology and Epidemiology.) Cardiac glycosides are found in certain flowering plants, such as oleander and lily-of-the-valley. Indigenous people in various parts of the world have used many plant extracts containing cardiac glycosides as arrow and ordeal poisons. The ancient Egyptians used squill (Urginea maritime) as a medicine. The Romans employed it as a diuretic, heart tonic, emetic, and rat poison. Digitalis, or foxglove, was mentioned in the year 1250 in the writings of Welsh physicians. Fuchsius described it botanically 300 years later and named it Digitalis purpurea. William Withering published his classic account of foxglove and some of its medical uses in 1785, remarking upon his experience with digitalis. He recognized many of the signs of digitalis toxicity, noting, "The foxglove, when given in very large and quickly repeated doses, occasions sickness, vomiting, purging, giddiness, confused vision, objects appearing green or yellow; increased secretion of urine, slow pulses, even as low as 35 in a minute, cold sweats, convulsions, syncope, death." (See Presentation and Workup.) During the early 20th century, as a result of the work of Cushny, Mackenzie, Lewis, and others, the drug was gradually recognized as specific for treatment of atrial fibrillation. Only subsequently was the value of digitalis for treatment of CHF established. Cardiac glycosides enhance cardiac contractility and slow conduction through the atrioventricular (AV) junction by increasing vagal tone.[3] (See Etiology.) Cardiac glycoside toxicity has been known to result from ingestion of some plants, including yellow oleander (Thevetia peruviana) and foxglove, and a similar toxidrome has been associated with the use of herbal dietary supplements that contain cardiac glycosides. Digoxin is among the top 50 prescribed drugs in the United States.[4] In 2011, the American Association of Poison Control Centers reported 1601 single exposures to cardiac glycoside drugs.[5] Cardiac glycosides account for 2.6% of toxic plant exposures in the United States.[6, 7] Most of these exposures are in children.[7] (See Epidemiology.) Digoxin-specific fragment antigen-binding (Fab) antibody fragments have contributed significantly to the improved morbidity and mortality of toxic patients since their approval in 1986 by the US Food and Drug Administration (FDA).
