What is Sepsis ? samer kareem 1,447 Views • 2 years ago

Sepsis occurs when chemicals released in the bloodstream to fight an infection trigger inflammation throughout the body. This can cause a cascade of changes that damage multiple organ systems, leading them to fail, sometimes even resulting in death. Symptoms include fever, difficulty breathing, low blood pressure, fast heart rate, and mental confusion. Treatment includes antibiotics and intravenous fluids.

Rheumatic Heart Disease
Rheumatic Heart Disease samer kareem 4,564 Views • 2 years ago

Rheumatic heart disease (RHD) is the most common acquired heart disease in children in many countries of the world, especially in developing countries. The global burden of disease caused by rheumatic fever currently falls disproportionately on children living in the developing world, especially where poverty is widespread. RHD is a chronic heart condition caused by rheumatic fever that can be prevented and controlled. Rheumatic fever is caused by a preceding group A streptococcal (strep) infection. Treating strep throat with antibiotics can prevent rheumatic fever. Moreover, regular antibiotics (usually monthly injections) can prevent patients with rheumatic fever from contracting further strep infections and causing progression of valve damage. Consequences of rheumatic heart disease Acute rheumatic fever primarily affects the heart, joints and central nervous system. The major importance of acute rheumatic fever is its ability to cause fibrosis of heart valves, leading to crippling valvular heart disease, heart failure and death. The decline of rheumatic fever in developed countries is believed to be the result of improved living conditions and availability of antibiotics for treatment of group A streptococcal infection. Overcrowding, poor housing conditions, undernutrition and lack of access to healthcare play a role in the persistence of this disease in developing countries.

Nelson's syndrome
Nelson's syndrome samer kareem 4,817 Views • 2 years ago

Nelson syndrome refers to a spectrum of symptoms and signs arising from an adrenocorticotropin (ACTH)–secreting pituitary macroadenoma after a therapeutic bilateral adrenalectomy. The spectrum of clinical features observed relates to the local effects of the tumor on surrounding structures, the secondary loss of other pituitary hormones, and the effects of the high serum concentrations of ACTH on the skin. [1] The first case was reported by Nelson et al in 1958. [2]

Knee injury ,Injuries - Everything You Need To Know - Dr. Nabil Ebraheim Scott 43 Views • 2 years ago

Dr. Ebraheim’s educational animated video describing the anatomy and associated injuries of the knee joint.
Disrupted quadriceps
•Patient is unable to actively extend the knee.
The most common cause of ACL ruptures:
•Traumatic force being applied during twisting motion.
•Side stepping or landing from a jump.
Patient complains of:
•Immediate pain
•Knee giving way
•Swelling
Aspiration of the knee
•If aspiration of the knee joint shows evidence of blood within the joint there is 75-80% chance of ACL and meniscal injury.
Lachamn’s test- ACL knee exam
•Knee is flexed at 30 degrees.
•ACL tear of the knee is identified by pulling on the tibia and examining the frontward motion of the lower leg in comparison to the upper leg.
Radiological exam – ACL
•MRI of the knee joint shows bone lesions or bruising associated with tears of the ACL. Injury is found in the typical location; middle of the femoral condyle and posterior part of the tibia laterally.
Posterior cruciate ligament tear (PCL)
•Common cause of injury is a bent knee hitting a dashboard in a car accident.
Tibial Sag Test –PCL knee exam
Quadriceps active test-PCL knee exam
•The examiner stabilizes the leg of the patient and then the patient is asked to actively contract the quadriceps muscle.
•The tibia is seen actively reduced from the posterior subluxed position.
Lachman’s test-PCL knee exam
•Knee is bent 20-30 degrees.
•The posterior drawer test is carried out while the patient is in a supine position and the knee is flexed to 90 degrees.
•The amount of translation of the tibia relative to the femur is observed.
The dial test is performed while the patient is in the supine or prone position and both knees are in 90 and 30 degrees of flexion. More than 10 degrees of external rotation indicates significant injury.
Common meniscal tears
Symptoms include
•Knee pain
•Pain with straightening the knee
•Swelling
•Locking
•Weakness

A silent heart attack is a heart attack that has few, if any, symptoms. You may have never had any symptoms to warn you that you've developed a heart problem, such as chest pain or shortness of breath. Having diabetes or prediabetes puts you at increased risk for heart disease and stroke. You can lower your risk by keeping your blood glucose (also called blood sugar), blood pressure, and blood cholesterol close to the recommended target numbersthe levels suggested by diabetes experts for good health.

Direct Laryngoscopy
Direct Laryngoscopy samer kareem 7,403 Views • 2 years ago

Visualization of the larynx by direct or indirect means is referred to as laryngoscopy and is the principal aim during airway management for passage of a tracheal tube. This paper presents a brief background regarding the development and practice of laryngoscopy and examines the equipment and techniques for both direct and indirect methods. Patient evaluation during the airway examination is discussed, as are predictors for difficult intubation. Laryngoscope blade design, newer intubating techniques, and a variety of indirect laryngoscopic technologies are reviewed, as is the learning curve for these techniques and devices.
