Myocardial rupture occurs in the setting of acute myocardial infarction (AMI), blunt and penetrating cardiac trauma, primary cardiac infection, primary and secondary cardiac tumors, infiltrative diseases of the heart, and aortic dissection. Myocardial rupture (or perforation) may also occur iatrogenically during percutaneous cardiac procedures (including device implantation) or open heart surgery (particularly valve replacement). Recently, myocardial rupture has been reported in the setting of stress cardiomyopathy (Takotsubo or regional ventricular ballooning syndrome). The clinical presentation of myocardial rupture depends on the mechanism and site of injury and the hemodynamic effects of the rupture. Mortality is extremely high unless early diagnosis is made and urgent surgical intervention is provided.
Acute respiratory distress syndrome (ARDS) occurs when fluid builds up in the tiny, elastic air sacs (alveoli) in your lungs. More fluid in your lungs means less oxygen can reach your bloodstream. This deprives your organs of the oxygen they need to function. ARDS typically occurs in people who are already critically ill or who have significant injuries. Severe shortness of breath — the main symptom of ARDS — usually develops within a few hours to a few days after the original disease or trauma. Many people who develop ARDS don't survive. The risk of death increases with age and severity of illness. Of the people who do survive ARDS, some recover completely while others experience lasting damage to their lungs.
Irritable bowel syndrome (IBS) is a common disorder that affects the large intestine (colon). Irritable bowel syndrome commonly causes cramping, abdominal pain, bloating, gas, diarrhea and constipation. IBS is a chronic condition that you will need to manage long term. Even though signs and symptoms are uncomfortable, IBS — unlike ulcerative colitis and Crohn's disease, which are forms of inflammatory bowel disease — doesn't cause changes in bowel tissue or increase your risk of colorectal cancer. Only a small number of people with irritable bowel syndrome have severe signs and symptoms. Some people can control their symptoms by managing diet, lifestyle and stress. Others will need medication and counseling.
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
Depression (major depressive disorder or clinical depression) is a common but serious mood disorder. It causes severe symptoms that affect how you feel, think, and handle daily activities, such as sleeping, eating, or working. To be diagnosed with depression, the symptoms must be present for at least two weeks.
Influenza is a viral infection that attacks your respiratory system — your nose, throat and lungs. Influenza, commonly called the flu, is not the same as stomach "flu" viruses that cause diarrhea and vomiting. For most people, influenza resolves on its own. But sometimes, influenza and its complications can be deadly. People at higher risk of developing flu complications include: Young children under 5, and especially those under 2 years Adults older than 65 Residents of nursing homes and other long-term care facilities Pregnant women and women up to two weeks postpartum People with weakened immune systems People who have chronic illnesses, such as asthma, heart disease, kidney disease and diabetes People who are very obese, with a body mass index (BMI) of 40 or higher Your best defense against influenza is to receive an annual vaccination.
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.
A pheochromocytoma (fee-o-kroe-moe-sy-TOE-muh) is a rare, usually noncancerous (benign) tumor that develops in cells in the center of an adrenal gland. You have two adrenal glands, one above each kidney. Your adrenal glands produce hormones that give instructions to virtually every organ and tissue in your body. If you have a pheochromocytoma, an adrenal gland releases hormones that cause persistent or episodic high blood pressure. If left untreated, a pheochromocytoma can result in severe or life-threatening damage to other body systems, especially the cardiovascular system. Most people with a pheochromocytoma are between the ages of 20 and 50, but the tumor can develop at any age. Surgical treatment to remove a pheochromocytoma usually returns blood pressure to normal.
Minimally invasive open thyroidectomy (MIT) is similar to conventional thyroidectomy in its surgical approach. The major difference is the length of the neck incision. A smaller incision improves cosmesis and reduces discomfort. Typically, a skin incision less than 6 cm is considered minimally invasive. The remainder of the procedure is exactly the same as is used in conventional thyroidectomy. Adaptations to this technique include transection rather than lateral retraction of the strap muscles (the Sofferman technique). [1]
Fulminant hepatic failure (FHF) or acute liver failure (ALF) is defined as the rapid development of acute liver injury with severe impairment of the synthetic function and hepatic encephalopathy in a patient without obvious, previous liver disease.
Non-alcoholic fatty liver disease (NAFLD) is a very common disorder and refers to a group of conditions where there is accumulation of excess fat in the liver of people who drink little or no alcohol. The most common form of NAFLD is a non serious condition called fatty liver.
Premature ventricular contractions (PVCs) are extra, abnormal heartbeats that begin in one of your heart's two lower pumping chambers (ventricles). These extra beats disrupt your regular heart rhythm, sometimes causing you to feel a flip-flop or skipped beat in your chest.
It is a specialized bodily fluid that supplies essential substances and nutrients, such as sugar, oxygen, and hormones to our cells, and carries waste away from those cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs (carbon dioxide). Blood also contains clotting agents.
Sepsis is a potentially life-threatening complication of an infection. Sepsis occurs when chemicals released into the bloodstream to fight the infection trigger inflammatory responses throughout the body. This inflammation can trigger a cascade of changes that can damage multiple organ systems, causing them to fail. If sepsis progresses to septic shock, blood pressure drops dramatically, which may lead to death. Anyone can develop sepsis, but it's most common and most dangerous in older adults or those with weakened immune systems. Early treatment of sepsis, usually with antibiotics and large amounts of intravenous fluids, improves chances for survival. Symptoms & causes Symptoms Many doctors view sepsis as a three-stage syndrome, starting with sepsis and progressing through severe sepsis to septic shock. The goal is to treat sepsis during its early stage, before it becomes more dangerous. Sepsis To be diagnosed with sepsis, you must exhibit at least two of the following symptoms, plus a probable or confirmed infection: Body temperature above 101 F (38.3 C) or below 96.8 F (36 C) Heart rate higher than 90 beats a minute Respiratory rate higher than 20 breaths a minute Severe sepsis Your diagnosis will be upgraded to severe sepsis if you also exhibit at least one of the following signs and symptoms, which indicate an organ may be failing: Significantly decreased urine output Abrupt change in mental status Decrease in platelet count Difficulty breathing Abnormal heart pumping function Abdominal pain Septic shock To be diagnosed with septic shock, you must have the signs and symptoms of severe sepsis — plus extremely low blood pressure that doesn't adequately respond to simple fluid replacement. When to see a doctor Most often sepsis occurs in people who are hospitalized. People in the intensive care unit are especially vulnerable to developing infections, which can then lead to sepsis. If you get an infection or if you develop signs and symptoms of sepsis after surgery, hospitalization or an infection, seek medical care immediately. Causes While any type of infection — bacterial, viral or fungal — can lead to sepsis, the most likely varieties include: Pneumonia Abdominal infection Kidney infection Bloodstream infection (bacteremia) The incidence of sepsis appears to be increasing in the United States. The causes of this increase may include: Aging population. Americans are living longer, which is swelling the ranks of the highest risk age group — people older than 65. Drug-resistant bacteria. Many types of bacteria can resist the effects of antibiotics that once killed them. These antibiotic-resistant bacteria are often the root cause of the infections that trigger sepsis. Weakened immune systems. More Americans are living with weakened immune systems, caused by HIV, cancer treatments or transplant drugs. Risk factors Sepsis is more common and more dangerous if you: Are very young or very old Have a compromised immune system Are already very sick, often in a hospital's intensive care unit Have wounds or injuries, such as burns Have invasive devices, such as intravenous catheters or breathing tubes Complications Sepsis ranges from less to more severe. As sepsis worsens, blood flow to vital organs, such as your brain, heart and kidneys, becomes impaired. Sepsis can also cause blood clots to form in your organs and in your arms, legs, fingers and toes — leading to varying degrees of organ failure and tissue death (gangrene). Most people recover from mild sepsis, but the mortality rate for septic shock is nearly 50 percent. Also, an episode of severe sepsis may place you at higher risk of future infections.
Neurogenic shock is a distributive type of shock resulting in low blood pressure, occasionally with a slowed heart rate, that is attributed to the disruption of the autonomic pathways within the spinal cord. It can occur after damage to the central nervous system such as spinal cord injury.
Pruritis is itchy skin that makes you want to scratch. It can be caused by many things. Normally, itchy skin isn't serious, but it can make you uncomfortable. Sometimes, itchy skin is caused by a serious medical condition. It can occur in association with a primary rash (e.g. dermatitis) or may occur because of hypersensitive nerves in the skin (neuropathic pruritus). ... Scratching a localised itch may lead to lichen simplex, prurigo or prurigo nodularis. Systemic causes of pruritus. Sytemic diseases may cause generalised pruritus.
The cornea occupies the front center part of the outer wall of the eye. It is made of collagen fibers in a very special arrangement so that the cornea is clear. One looks through the cornea to see the iris and pupil. The cornea bends light coming into the eye so that it is focused on the retina.
Shoulder dystocia is a rare emergency that can happen during the end of the second stage of labour. It's all to do with how your baby moves down through your vagina and out into the world. Shoulder dystocia happens when your baby's head has been born, but one of her shoulders becomes stuck.
