Medial Medullary Syndrome
Medial Medullary Syndrome samer kareem 1,571 Views • 3 years ago

Medial medullary syndrome, also known as Dejerine syndrome, represents less than 1% of brainstem stroke syndromes. Thrombotic or embolic occlusion of small perforating branches from vertebral or proximal basilar artery supplying the medial aspect of medulla oblongata cause this rare syndrome. It is characterized by contralateral hemiplegia/hemiparesis as well as hemisensory loss with ipsilateral hypoglossal palsy (ipsilateral tongue weakness and atrophy) from involvement of CN XII nucleus. Other manifestations e.g. vertigo, nausea, ipsilateral limb ataxia are also reported.

heart failure
heart failure samer kareem 2,185 Views • 3 years ago

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently. Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer. Lifestyle changes — such as exercising, reducing salt in your diet, managing stress and losing weight — can improve your quality of life. One way to prevent heart failure is to control conditions that cause heart failure, such as coronary artery disease, high blood pressure, diabetes or obesity.

Carotid Endarterectomy
Carotid Endarterectomy samer kareem 1,606 Views • 3 years ago

A carotid endarterectomy is performed in a sterile surgical suite or standard operating room. You may go home the same day or stay 1–2 nights after the procedure depending on your medical condition. You receive a local anesthetic or general anesthesia. Your vascular surgeon makes an incision at the front of your neck. After removing the plaque from the artery your vascular surgeon repairs the artery by stitching in a natural graft (formed from a piece of vein from elsewhere in your body) or a woven patch. The incision is closed

Bruton's X linked agammaglobulinemia
Bruton's X linked agammaglobulinemia samer kareem 3,580 Views • 3 years ago

X-linked agammaglobulinemia (XLA), or Bruton agammaglobulinemia, is an inherited immunodeficiency disease caused by mutations in the gene coding for Bruton tyrosine kinase (BTK). The disease was first elucidated by Bruton in 1952, for whom the gene is named. BTK is critical to the maturation of pre–B cells to differentiating mature B cells. The BTK gene defect has been mapped to the long arm of the X chromosome at band Xq21.3 to Xq22, spanning 37.5kb with 19 exons forming 659 amino acids to complete the BTK cytosolic tyrosine kinase. A database of BTK mutations (BTKbase: Mutation registry for X-linked agammaglobulinemia) lists 544 mutation entries from 471 unrelated families showing 341 unique molecular events. No single mutation accounts for more than 3% of mutations in patients. In addition to mutations, a number of variants or polymorphisms have been found.

Severe combined immunodeficiency
Severe combined immunodeficiency samer kareem 1,769 Views • 3 years ago

Severe combined immunodeficiency (SCID) is a life-threatening syndrome of recurrent infections, diarrhea, dermatitis, and failure to thrive. It is the prototype of the primary immunodeficiency diseases and is caused by numerous molecular defects that lead to severe compromise in the number and function of T cells, B cells, and occasionally natural killer (NK) cells. Clinically, most patients present before age 3 months. Without intervention, SCID usually results in severe infection and death in children by age 2 years. A committee of experts, initially sponsored by the World Health Organization (WHO), meets every 2 years with the goal to classify the group of primary immunodeficiency diseases according to current understanding of the pathways that become defective in the immune system.[1] Eight classification groups have been determined, with SCID being one of the best studied. Over the past few decades, the diverse molecular genetic causes of SCID have been identified with progress from studies of the immune system.[2] SCID is considered a pediatric emergency because survival depends on expeditious stem cell reconstitution, usually by bone marrow transplantation (BMT). Appropriate diagnosis is essential because instituting proper treatment is lifesaving. Despite the heterogeneity in the pathogenesis of immune defects, common cutaneous manifestations and typical infections can provide clinical clues in diagnosing this pediatric emergency.[3] Skin manifestations were prevalent in primary immunodeficiency disorders studied in 128 pediatric patients in Kuwait; skin infections were the most prevalent findings, seen in 39 patients (30%), followed by dermatitis in 24 (19%).[4] Skin infections were significantly more prevalent in those with congenital defects in phagocyte number, function, or both, as well as in those with well-defined immunodeficiencies. Dermatitis was evident in all patients with hyper–immunoglobulin (Ig) E syndrome and Wiskott-Aldrich syndrome.[4] Erythroderma of infancy with diffuse alopecia was seen exclusively in patients with SCID disorders, and telangiectasia in patients with ataxia telangiectasia; and partial albinism with silvery gray hair was associated with Chediak-Higashi syndrome. With the advances in BMT and gene therapy, patients now have a better likelihood of developing a functional immune system in a previously lethal genetic disease. However, once an infant develops serious infections, intervention is rarely successful.

Massive Dermoid Cyst
Massive Dermoid Cyst samer kareem 2,785 Views • 3 years ago

The term dermoid cyst does not appear to be restricted to a single kind of lesion nor is it used in only a single medical discipline. The term dermoid cyst can be found in the vocabulary of dermatologists, dermatopathologists, general pathologists, gynecologists, neurosurgeons, or pediatricians. If asked, all of these clinicians would most probably define and describe dermoid cysts differently. For example, gynecologists and general pathologists might say that a dermoid cyst is a cystic tumor of the ovary. In contrast, neurosurgeons tend to view a dermoid cyst is associated with a congenital cyst of the spine or an intracranial congenital cyst. For pediatricians and dermatologists, dermoid cyst means subcutaneous cysts, which are usually congenital.[1]

Leg Ulcers
Leg Ulcers samer kareem 2,009 Views • 3 years ago

A leg ulcer is simply a break in the skin of the leg, which allows air and bacteria to get into the underlying tissue. This is usually caused by an injury, often a minor one that breaks the skin. In most people such an injury will heal up without difficulty within a week or two. However, when there is an underlying problem the skin does not heal and the area of breakdown can increase in size. This is a chronic leg ulcer.

Achilles Suture Bridge
Achilles Suture Bridge Mohamed Ibrahim 2,470 Views • 3 years ago

The Arthrex SpeedBridge™ is an innovative soft tissue fixation device used in the treatment of Achilles injuries. While standard anchor fixation of the tendon creates only a single point of compression directly over the anchor, the SpeedBridge enables an hourglass pattern of FiberTape® suture to be laid over the distal end of the tendon. This four-anchor construct enables a true knotless repair and a greater area of compression for the Achilles tendon on the calcaneus, improving stability and possibly allowing for earlier return to normal activities.

Breast Cancer Screening Recommendations Breast cancer screening is important for all women. If you are at higher risk of breast cancer, you may need to be screened earlier and more often than women at average risk. Breast cancer screening is only recommended for some men at very high risk due to an inherited gene mutation or a strong family history of breast cancer.

Premature Ejaculation - Causes and how to Avoid it
Premature Ejaculation - Causes and how to Avoid it samer kareem 44,901 Views • 3 years ago

Premature ejaculation occurs when a man ejaculates sooner during sexual intercourse than he or his partner would like. Premature ejaculation is a common sexual complaint. Estimates vary, but as many as 1 out of 3 men say they experience this problem at some time. As long as it happens infrequently, it's not cause for concern. However, you may meet the diagnostic criteria for premature ejaculation if you: Always or nearly always ejaculate within one minute of penetration Are unable to delay ejaculation during intercourse all or nearly all of the time Feel distressed and frustrated, and tend to avoid sexual intimacy as a result Both psychological and biological factors can play a role in premature ejaculation. Although many men feel embarrassed to talk about it, premature ejaculation is a common and treatable condition. Medications, counseling and sexual techniques that delay ejaculation — or a combination of these — can help improve sex for you and your partner.

The heart makers
The heart makers samer kareem 2,091 Views • 3 years ago

How do you make a working human heart? Scientists can turn stem cells into beating heart cells, but getting them to organize into a 3D heart requires a scaffold. At the Massachusetts General Hospital in Boston, Harald Ott and his team are reusing the scaffold that nature provides. They’re stripping away all the living cells from dead hearts, before filling in the leftover matrix with healthy new cells. In this video, Brendan Maher finds out how the technique could be used to develop parts of the heart, like the aortic root and valve, for transplant.

Epley Maneuver  Vertigo
Epley Maneuver Vertigo samer kareem 1,484 Views • 3 years ago

Epley maneuver: Step 1 You will sit on the doctor's exam table with your legs extended in front of you. The doctor will turn your head so that it is halfway between looking straight ahead and looking directly to the side that causes the worst vertigo. Without changing your head position, the doctor will guide you back quickly so that your shoulders are on the table but your head is hanging over the edge of the table. In this position, the side of your head that is causing the worst vertigo is facing the floor. The doctor will hold you in this position for 30 seconds or until your vertigo stops. Epley maneuver: Step 2 Then, without lifting up your head, the doctor will turn your head to look at the same angle to the opposite side, so that the other side of your head is now facing the floor. The doctor will hold you in this position for 30 seconds or until your vertigo stops. Epley maneuver: Step 3 The doctor will help you roll in the same direction you are facing so that you are now lying on your side. (For example, if you are looking to your right, you will roll onto your right side.) The side that causes the worst vertigo should be facing up. The doctor will hold you in this position for another 30 seconds or until your vertigo stops. Epley maneuver: Step 4 The doctor will then help you to sit back up with your legs hanging off the table on the same side that you were facing. This maneuver is done with the assistance of a doctor or physical therapist. A single 10- to 15-minute session usually is all that is needed. When your head is firmly moved into different positions, the crystal debris (canaliths) causing vertigo will move freely and no longer cause symptoms.

Electrical Injuries
Electrical Injuries samer kareem 2,226 Views • 3 years ago

Electrical injuries can present with a variety of problems, including cardiac or respiratory arrest, coma, blunt trauma, and severe burns of several types. It is important to establish the type of exposure (high or low voltage), duration of contact, and concurrent trauma. Low-voltage AC injury without loss of consciousness and/or arrest These injuries are exposures of less than 1000V and usually occur in the home or office setting. Typically, children with electrical injuries present after biting or chewing on an electrical cord and suffer oral burns. Adults working on home appliances or electrical circuits can also experience these electrical injuries. Low-voltage AC may result in significant injury if there is prolonged, tetanic muscle contraction. Low-voltage AC injury with loss of consciousness and/or arrest In respiratory arrest or ventricular fibrillation that is not witnessed, an electrical exposure may be difficult to diagnose. All unwitnessed arrests should include this possibility in the differential diagnosis. Query EMS personnel, family, and coworkers about this possibility. Inquire if a scream was heard before the patient’s collapse; this may be due to involuntary contraction of chest wall muscles from electrical current. High-voltage AC injury without loss of consciousness and/or arrest Usually high-voltage injuries do not cause loss of consciousness but instead cause devastating thermal burns. In occupational exposures, details of voltage can be obtained from the local power company. High-voltage AC injury with loss of consciousness and/or arrest This is an unusual presentation of high-voltage AC injuries, which do not often cause loss of consciousness. History may need to come from bystanders or EMS personnel. Direct current (DC) injury These injuries typically cause a single muscle contraction that throws the victim away from the source. They are rarely associated with loss of consciousness unless there is severe head trauma, and victims can often provide their own history. Conducted electrical devices Conducted electrical weapons (CEWs) such as tasers are weapons used by law enforcement that deliver high-voltage current that is neither true AC or DC but is most like a series of low-amplitude DC shocks.[16] They can deliver 50,000 V in a 5-second pulse, with an average current of 2.1 mA.[17] Though they have been temporally associated with deaths in the law enforcement setting, conducted electrical devices (CEDs) in healthy volunteers have been shown to be safe without evidence of delayed arrhythmia or cardiac damage as measured by troponin I.[18, 17] One study of their use in 1201 law enforcement incidents showed mostly superficial puncture wounds from the device probes, and significant injuries only from trauma subsequent to shock, not from the device itself. Of 2 deaths in custody, neither was related to CEW exposure.[19]

Subarachnoid Hemorrhage
Subarachnoid Hemorrhage samer kareem 3,257 Views • 3 years ago

Subarachnoid hemorrhage is bleeding in the space between your brain and the surrounding membrane (subarachnoid space). Bleeding usually results from the rupture of an abnormal bulge in a blood vessel in your brain (brain aneurysm). Sometimes an abnormal tangle of blood vessels in your brain (arteriovenous malformation), trauma or other events cause bleeding. A subarachnoid hemorrhage may lead to permanent brain damage or death if not treated.
