“People need to realize this is imminently preventable,” he said. Lyme disease develops following an infection with the bacteria Borrelia burgdorferi. It's transmitted to humans through the bite of infected blacklegged ticks. The tick must be attached to its host for 36 to 48 hours to transmit the bacteria.

Ectopia cordis is a rare genetic defect. During a baby’s development in utero, their chest wall doesn’t form correctly. It also doesn’t fuse together as it normally would. This prevents the heart from developing where it should, leaving it defenseless and exposed outside of the protection of the chest wall. The defect affects about one in 126,000 births. In partial ectopia cordis, the heart is located outside the chest wall, but just under the skin. The heart can be seen beating through the skin.

Parkinson's part 1
Parkinson's part 1 samer kareem 6,140 Views • 2 years ago

Parkinson's disease is a progressive disorder of the nervous system that affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while a tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement. In the early stages of Parkinson's disease, your face may show little or no expression, or your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson's disease symptoms worsen as your condition progresses over time. Although Parkinson's disease can't be cured, medications may markedly improve your symptoms. In occasional cases, your doctor may suggest surgery to regulate certain regions of your brain and improve your symptoms.

Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy the entire larynx is removed and in a partial laryngectomy only a portion is taken out. The laryngectomee breathes through an opening in the neck known as a stoma.

Understanding MRIs
Understanding MRIs samer kareem 21,343 Views • 2 years ago

Magnetic resonance imaging (MRI) can be an important tool in the diagnosis of multiple sclerosis (MS). MRI can also be used to monitor the progression of the disease in people living with MS. How does it work? MRI uses very strong magnets, radio signals, and computer software to take 3-dimensional pictures of the inside of the body. Will I need contrast material? Maybe. Contrast material is a substance that temporarily changes the way imaging tools interact with the body. They are often used to visualize certain types of MS disease activity on the MRI. If your doctor thinks your scan requires this contrast material, you may get an injection before you get in the MRI machine. How long will it take? The time may vary based on the type of MRI. Be sure to discuss with your doctor in advance so he or she can provide you with exact timing. But don’t worry, you won’t have to stay still the whole time. The technician will let you know when they’re starting a new image.

Ankle fusion (arthrodesis) This is a surgical procedure which joins together the main bones of the ankle joint (the tibia and the talus). However, depending on the technique your surgeon will use, occasionally the fibula will be included in this procedure. The two joint surfaces which generate the pain are removed.

Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,147 Views • 2 years ago

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.

Chordoid meningioma
Chordoid meningioma samer kareem 14,368 Views • 2 years ago

Chordoid meningioma, classified as atypical meningioma according to the World Health Organisation (WHO) classification, is a rare subtype, which represents only 0.5% of all meningiomas and is associated with a high incidence of recurrence. Multiple intracranial meningiomas are rare in non-neurofibromatosis patients. We present a female patient with both of these rare types of meningioma. The patient presented with two concurrent intracranial meningiomas, with one a meningotheliomatous subtype and the other a chordoid meningioma. Given the wide array of histological differential diagnoses in chordoid meningioma, immunohistochemistry has a significant role to play in differentiating them. Recurrence in chordoid meningioma can be generally predicted based on the extent of resection, the percentage of chordoid element, and proliferation indices.

Emergency Pericardiocentesis
Emergency Pericardiocentesis samer kareem 7,830 Views • 2 years ago

Pericardiocentesis is the aspiration of fluid from the pericardial space that surrounds the heart. This procedure can be life saving in patients with cardiac tamponade, even when it complicates acute type A aortic dissection and when cardiothoracic surgery is not available. [1] Cardiac tamponade is a time sensitive, life-threatening condition that requires prompt diagnosis and management. Historically, the diagnosis of cardiac tamponade has been based on clinical findings. Claude Beck, a cardiovascular surgeon, described 2 triads of clinical findings that he found associated with acute and chronic cardiac tamponade. The first of these triads consisted of hypotension, an increased venous pressure, and a quiet heart. It has come to be recognized as Beck's triad, a collection of findings most commonly produced by acute intrapericardial hemorrhage. Subsequent studies have shown that these classic findings are observed in only a minority of patients with cardiac tamponade. [2] The detection of pericardial fluid has been facilitated by the development and continued improvement of echocardiography. [3] Cardiac ultrasound is now accepted as the criterion standard imaging modality for the assessment of pericardial effusions and the dynamic findings consistent with cardiac tamponade. With echocardiography, the location of the effusion can be identified, the size can be estimated (small, medium, or large), and the hemodynamic effects can be examined by assessing for abnormal septal motion, right atrial or right ventricular inversion, and decreased respiratory variation of the diameter of the inferior vena cava.

In nonsurgical treatment, progressive physical therapy and rehabilitation can restore the knee to a condition close to its pre-injury state and educate the patient on how to prevent instability.37, 38 This may be supplemented with the use of a hinged knee brace. However, many people who choose not to have surgery may experience secondary injury to the knee due to repetitive instability episodes. Surgical treatment is usually advised in dealing with combined injuries (ACL tears in combination with other injuries in the knee). However, deciding against surgery is reasonable for select patients. Nonsurgical management of isolated ACL tears is likely to be successful or may be indicated in patients:

Children are not little adults, which is why even the simplest of procedures requires a hospital that is 100 percent dedicated to caring for children. Children’s Mercy is one of only 10 centers in the country to be as recognized as a Level 1 Children’s Surgery Center, the highest possible rating. The result? An organization with pediatrics specialists in every subspecialty that sets the standard of care instead of just practicing it.
