Irregular Menstrual Cycle
Irregular Menstrual Cycle samer kareem 1,716 Views • 3 years ago

Menstruation is the time of month when the womb (uterus) sheds its lining and vaginal bleeding occurs. This is known as a menstrual period. Periods vary widely from woman to woman. Some periods are punctual, some are unpredictable. On average, a woman gets her period every 24 to 38 days. A period usually lasts about two to eight days. Irregular periods may require treatment. What Are Irregular Periods? You may have irregular periods if: The time between each period starts to change. You are losing more or less blood during a period than usual. The number of days that your period lasts varies significantly. There are different terms for different types of irregular periods: Irregular Menstrual Bleeding (IrregMB): Bleeding of more than 20 days in individual cycle lengths over a period of one year. Absent Menstrual Bleeding (amenorrhea): No bleeding in a 90-day period. Heavy Menstrual Bleeding (HMB): Excessive menstrual blood loss that interferes with the woman’s physical, emotional, social, and material quality of life and can occur alone or in combination with other symptoms. Heavy and Prolonged Menstrual Bleeding (HPMB): Less common than HMB. It is important to make a distinction from HMB given they may have different etiologies and respond to different therapies. Light Menstrual Bleeding: Based on patient complaint, rarely related to pathology.

Empyema can develop after you have pneumonia. Many different types of bacteria may cause pneumonia, but the two most common are Streptococcus pneumoniae and Staphylococcus aureus. Occasionally, empyema may happen after you've had surgery on your chest. Medical instruments can transfer bacteria into your pleural cavity

Marfan Syndrome Diagnosis and Treatment
Marfan Syndrome Diagnosis and Treatment samer kareem 9,843 Views • 3 years ago

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.

Thoracic outlet syndrome surgery
Thoracic outlet syndrome surgery samer kareem 1,793 Views • 3 years ago

Thoracic outlet syndrome is a group of disorders that occur when blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) are compressed. This can cause pain in your shoulders and neck and numbness in your fingers. Common causes of thoracic outlet syndrome include physical trauma from a car accident, repetitive injuries from job- or sports-related activities, certain anatomical defects (such as having an extra rib), and pregnancy. Sometimes doctors can't determine the cause of thoracic outlet syndrome. Treatment for thoracic outlet syndrome usually involves physical therapy and pain relief measures. Most people improve with these approaches. In some cases, however, your doctor may recommend surgery.

Heart transplantation
Heart transplantation samer kareem 2,295 Views • 3 years ago

Finding a donor heart can be difficult. The heart must be donated by someone who is brain-dead but is still on life support. The donor heart must be matched as closely as possible to your tissue type to reduce the chance that your body will reject it. You are put into a deep sleep with general anesthesia, and a cut is made through the breastbone. Your blood flows through a heart-lung bypass machine while the surgeon works on your heart. This machine does the work of your heart and lungs while they are stopped, and supplies your body with blood and oxygen. Your diseased heart is removed and the donor heart is stitched in place. The heart-lung machine is then disconnected. Blood flows through the transplanted heart, which takes over supplying your body with blood and oxygen. Tubes are inserted to drain air, fluid, and blood out of the chest for several days, and to allow the lungs to fully re-expand.

Chronic Pancreatitis samer kareem 2,080 Views • 3 years ago

Chronic pancreatitis is a long-standing inflammation of the pancreas that alters the organ's normal structure and functions. It can present as episodes of acute inflammation in a previously injured pancreas, or as chronic damage with persistent pain or malabsorption.

Dislocation of the Temporomandibular Joint
Dislocation of the Temporomandibular Joint samer kareem 7,215 Views • 3 years ago

The temporomandibular joint (TMJ), located just in front of the lower part of the ear, allows the lower jaw to move. The TMJ is a ball-and-socket joint, just like the hip or shoulder. When the mouth opens wide, the ball (called the condyle) comes out of the socket and moves forward, going back into place when the mouth closes. TMJ becomes dislocated when the condyle moves too far and gets stuck in front of a bony prominence called the articular eminence. The condyle can't move back into place. This happens most often when the ligaments that normally keep the condyle in place are somewhat loose, allowing the condyle to move beyond the articular eminence. The surrounding muscles often go into spasm and hold the condyle in the dislocated position.

Pick's Dementia: samer kareem 1,451 Views • 3 years ago

Frontotemporal dementia (frontotemporal lobar degeneration) is an umbrella term for a diverse group of uncommon disorders that primarily affect the frontal and temporal lobes of the brain — the areas generally associated with personality, behavior and language. In frontotemporal dementia, portions of these lobes shrink (atrophy). Signs and symptoms vary, depending upon the portion of the brain affected. Some people with frontotemporal dementia undergo dramatic changes in their personality and become socially inappropriate, impulsive or emotionally indifferent, while others lose the ability to use language.

Knee Pain

Knee pain facts Knee pain is a common problem with many causes, from acute injuries to complications of medical conditions. Knee pain can be localized to a specific area of the knee or be diffuse throughout the knee. Knee pain is often accompanied by physical restriction. A thorough physical examination will usually establish the diagnosis of knee pain. The treatment of knee pain depends on the underlying cause. The prognosis of knee pain is usually good although it might require surgery or other interventions.

Removing a hump from the bridge is one of the most common things people want addressed during their rhinoplasty. Nasal humps can range widely in size. Perhaps you just have a small bump that you'd like refined? Or maybe you have more of a Roman Nose with a more dominating, distracting large hump? No matter if your nose falls on one of these extremes or somewhere in between rhinoplasty surgery can be used to reshape your nose. For anyone considering having a rhinoplasty to reduce a hump on their bridge there are several things to consider before having surgery.

Renal Artery Aneurysm Repair
Renal Artery Aneurysm Repair samer kareem 7,358 Views • 3 years ago

Indications for intervention in patients with a renal artery aneurysm (RAA) include the following [20, 8, 13, 14] : Rupture Symptomatic RAA - Hypertension (from associated renal artery stenosis, refractory to medical management), pain, renal ischemia or infarction secondary to embolization from the aneurysm sac RAAs in females who are pregnant or are contemplating pregnancy Diameter greater than 2 cm Enlarging RAA RAA associated with acute dissection Currently, there is no consensus regarding the size at which an RAA should be repaired in an asymptomatic patient. Experts have recommended RAA repair at diameters ranging from 1.5 to 3 cm, [8] though most suggest 2 cm. Some reports have even suggest that larger asymptomatic saccular aneurysms may be managed expectantly. Note that aneurysm rupture at a diameter of 1.5 cm has been reported. Complete calcification of the wall of the aneurysm sac manifests in about 40% of patients. This was once believed to confer protection against rupture [21] ; however, this belief has since been questioned. [30] Asymptomatic, small (<2 cm in diameter) RAAs do not usually require treatment. One notable exception is an RAA in a woman who is pregnant or contemplating pregnancy. In view of the increased risk of rupture in such cases, even small asymptomatic aneurysms should be repaired in this population. For diagnosis and preinterventional planning, gadolinium-enhanced magnetic resonance angiography (MRA) and computed tomography (CT) angiography (CTA) with three-dimensional (3D) reconstruction have essentially replaced conventional arteriography. Regular follow-up examination with ultrasonography (US) or CT) is recommended in patients who are treated expectantly. Spontaneous cure by thrombosis of small aneurysms has been described. Further refinements in endovascular techniques may allow more RAAs to be treated in this manner. So far, excellent short- and intermediate-term results have been described in the literature [40] ; however, there remains a need for further long-term outcome data.

Digoxin is used to treat heart failure, usually along with other medications. It is also used to treat a certain type of irregular heartbeat (chronic atrial fibrillation). Treating heart failure may help maintain your ability to walk and exercise and may improve the strength of your heart. Treating an irregular heartbeat can decrease the risk for blood clots, an effect that may reduce your risk for a heart attack or stroke.

Wash your hands thoroughly with soap and water before and after treating the wound. Wash the area with mild soap and running water to reduce the risk of infection. Pat dry. Apply antibiotic ointment and cover with a clean bandage or sterile dressing. Antibiotic prophylaxis should be considered, especially if there is a high risk of infection, such as with cat bites, with puncture wounds, with wounds to the hand, and in persons who are immunosuppressed. Amoxicillin/clavulanate is the first-line prophylactic antibiotic.

6 987 24 MORE How Does Anesthesia Work? Credit: itsmejust | Shutterstock If you’ve ever had surgery, unless you are super tough, you’ve gone through it with the benefit of anesthetics. But, how do these body-numbing elixirs work? Prior to the invention of anesthesia in the mid-1800s, surgeons had to hack off limbs, sew up wounds and remove mysterious growths with nothing to dull the patient's pain but opium or booze. While these drugs may have numbed the patient, they didn’t always completely block the pain, or erase the memory of it. Since then, doctors have gotten much better at putting us out with drug combinations that ease pain, relax muscles and, in some cases, put us in a deep state of hypnosis that gives us temporary amnesia. Today, there are two primary types of anesthesia drugs: those that knockout the whole body (general) and those that only numb things up locally.
