Pregnancy occurs when an egg is fertilized by a sperm, grows inside a woman's uterus (womb), and develops into a baby. In humans, this process takes about 264 days from the date of fertilization of the egg, but the obstetrician will date the pregnancy from the first day of the last menstrual period (280 days 40 weeks).
Keyhole surgery can be helpful for patients with brain, pituitary and skull base tumors. With cutting edge technology and a proven track record in keyhole and endonasal endoscopic approaches, we make surgery safer, less invasive and more effective.
A burn is tissue damage that results from scalding, overexposure to the sun or other radiation, contact with flames, chemicals or electricity, or smoke inhalation. Is it a major or minor burn? Call 911 or seek immediate care for major burns, which: Are deep Cause the skin to be dry and leathery May appear charred or have patches of white, brown or black Are larger than 3 inches (about 8 centimeters) in diameter or cover the hands, feet, face, groin, buttocks or a major joint A minor burn that doesn't require emergency care may involve: Superficial redness similar to a sunburn Pain Blisters An area no larger than 3 inches (about 8 centimeters) in diameter Treating major burns Until emergency help arrives: Protect the burned person from further harm. If you can do so safely, make sure the person you're helping is not in contact with the source of the burn. For electrical burns, make sure the power source is off before you approach the burned person. Make certain that the person burned is breathing. If needed, begin rescue breathing if you know how. Remove jewelry, belts and other restrictive items, especially from around burned areas and the neck. Burned areas swell rapidly. Cover the area of the burn. Use a cool, moist bandage or a clean cloth. Don't immerse large severe burns in water. Doing so could cause a serious loss of body heat (hypothermia). Elevate the burned area. Raise the wound above heart level, if possible. Watch for signs of shock. Signs and symptoms include fainting, pale complexion or breathing in a notably shallow fashion. Treating minor burns For minor burns: Cool the burn. Hold the burned area under cool (not cold) running water or apply a cool, wet compress until the pain eases. Remove rings or other tight items from the burned area. Try to do this quickly and gently, before the area swells. Don't break blisters. Fluid-filled blisters protect against infection. If a blister breaks, clean the area with water (mild soap is optional). Apply an antibiotic ointment. But if a rash appears, stop using the ointment. Apply lotion. Once a burn is completely cooled, apply a lotion, such as one that contains aloe vera or a moisturizer. This helps prevent drying and provides relief. Bandage the burn. Cover the burn with a sterile gauze bandage (not fluffy cotton). Wrap it loosely to avoid putting pressure on burned skin. Bandaging keeps air off the area, reduces pain and protects blistered skin. If needed, take an over-the-counter pain reliever, such as ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve) or acetaminophen (Tylenol, others).
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
The annual incidence of primary intraspinal neoplasm is approximately five per million for females and three per million for males.[9] Spinal intradural extramedullary tumors account for two thirds of all intraspinal neoplasms and include neuromas and meningiomas.[1] Overall, meningiomas account for 25 to 46% of primary spinal neoplasms and are the second most common intradural spine tumor after neuromas.[9] Spinal meningiomas occur less frequently than intracranial ones and account for approximately 7.5 to 12.7% of all meningiomas.[25]
Rheumatic fever is an inflammatory disease that can develop as a complication of inadequately treated strep throat or scarlet fever. Strep throat and scarlet fever are caused by an infection with streptococcus bacteria. Rheumatic fever is most common in 5- to 15-year-old children, though it can develop in younger children and adults. Although strep throat is common, rheumatic fever is rare in the United States and other developed countries. However, rheumatic fever remains common in many developing nations. Rheumatic fever can cause permanent damage to the heart, including damaged heart valves and heart failure. Treatments can reduce damage from inflammation, lessen pain and other symptoms, and prevent the recurrence of rheumatic fever.
Ehlers-Danlos syndrome is a group of disorders that affect the connective tissues that support the skin, bones, blood vessels, and many other organs and tissues. Defects in connective tissues cause the signs and symptoms of Ehlers-Danlos syndrome, which vary from mildly loose joints to life-threatening complications. Previously, there were more than 10 recognized types of Ehlers-Danlos syndrome, differentiated by Roman numerals. In 1997, researchers proposed a simpler classification that reduced the number of major types to six and gave them descriptive names: the classical type (formerly types I and II), the hypermobility type (formerly type III), the vascular type (formerly type IV), the kyphoscoliosis type (formerly type VIA), the arthrochalasia type (formerly types VIIA and VIIB), and the dermatosparaxis type (formerly type VIIC). This six-type classification, known as the Villefranche nomenclature, is still commonly used. The types are distinguished by their signs and symptoms, their underlying genetic causes, and their patterns of inheritance. Since 1997, several additional forms of the condition have been described. These additional forms appear to be rare, affecting a small number of families, and most have not been well characterized.
The DASH diet is a lifelong approach to healthy eating that's designed to help treat or prevent high blood pressure (hypertension). The DASH diet encourages you to reduce the sodium in your diet and eat a variety of foods rich in nutrients that help lower blood pressure, such as potassium, calcium and magnesium.
The menstrual cycle is the regular natural change that occurs in the female reproductive system like the uterus and ovaries that make pregnancy possible. The cycle is required for the production of ovocytes, and for the preparation of the uterus for pregnancy.
The syndrome of inappropriate antidiuretic hormone (ADH) secretion (SIADH) is defined by the hyponatremia and hypo-osmolality resulting from inappropriate, continued secretion or action of the hormone despite normal or increased plasma volume, which results in impaired water excretion.
Adrenoleukodystrophy, or ALD, is a deadly genetic disease that affects 1 in 18 000 people. It most severely affects boys and men. This brain disorder destroys myelin, the protective sheath that surrounds the brain's neurons -- the nerve cells that allow us to think and to control our muscles.
