Intracranial Pressure samer kareem 9,662 Views • 2 years ago

Intracranial pressure (ICP) is the pressure inside the skull and thus in the brain tissue and cerebrospinal fluid (CSF). ICP is measured in millimeters of mercury (mmHg) and, at rest, is normally 7–15 mmHg for a supine adult.

Diabetic retinopathy involves changes to retinal blood vessels that can cause them to bleed or leak fluid, distorting vision. Diabetic retinopathy is the most common cause of vision loss among people with diabetes and a leading cause of blindness among working-age adults.

Severe combined immunodeficiency
Severe combined immunodeficiency samer kareem 1,698 Views • 2 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.

Thalassaemia is simple
Thalassaemia is simple samer kareem 18,791 Views • 2 years ago

Thalassemia (thal-uh-SEE-me-uh) is an inherited blood disorder characterized by less hemoglobin and fewer red blood cells in your body than normal. Several types of thalassemia exist, including alpha-thalassemia, beta-thalassemia intermedia, Cooley's anemia and Mediterranean anemia. Hemoglobin is the substance in your red blood cells that allows them to carry oxygen. The low hemoglobin and fewer red blood cells of thalassemia may cause anemia, leaving you fatigued. If you have mild thalassemia, you may not need treatment. But, if you have a more severe form of thalassemia, you may need regular blood transfusions. You can also take steps on your own to cope with fatigue, such as choosing a healthy diet and exercising regularly.

Massive Pulmonary Embolus
Massive Pulmonary Embolus samer kareem 1,458 Views • 2 years ago

Pulmonary embolism symptoms can vary greatly, depending on how much of your lung is involved, the size of the clots, and whether you have underlying lung or heart disease. Common signs and symptoms include: Shortness of breath. This symptom typically appears suddenly and always gets worse with exertion. Chest pain. You may feel like you're having a heart attack. The pain may become worse when you breathe deeply (pleurisy), cough, eat, bend or stoop. The pain will get worse with exertion but won't go away when you rest. Cough. The cough may produce bloody or blood-streaked sputum. Other signs and symptoms that can occur with pulmonary embolism include: Leg pain or swelling, or both, usually in the calf Clammy or discolored skin (cyanosis) Fever Excessive sweating Rapid or irregular heartbeat Lightheadedness or dizziness

Optimal blood pressure typically is defined as 120 mm Hg systolic — which is the pressure as your heart beats — over 80 mm Hg diastolic — which is the pressure as your heart relaxes. For your resting heart rate, the target is between 60 and 100 beats per minute (bpm)

Removing a 20-CM Long Loa Loa Worm from the Eye Scott 4,413 Views • 2 years ago

Loa loa filariasis (also known as loiasis, loaiasis, Calabar swellings, Fugitive swelling, Tropical swelling and African eyeworm) is a skin and eye disease caused by the nematode worm, loa loa. Humans contract this disease through the bite of a Deer fly or Mango fly (Chrysops spp), the vectors for Loa loa. The adult Loa loa filarial worm migrates throughout the subcutaneous tissues of humans, occasionally crossing into subconjunctival tissues of the eye where it can be easily observed. Loa loa does not normally affect one's vision but can be painful when moving about the eyeball or across the bridge of the nose.The disease can cause red itchy swellings below the skin called "Calabar swellings". The disease is treated with the drug diethylcarbamazine (DEC), and when appropriate, surgical methods may be employed to remove adult worms from the conjunctiva.

Finger Dislocation & Metacarpal Block
Finger Dislocation & Metacarpal Block samer kareem 2,197 Views • 2 years ago

Finger metacarpophalangeal (MCP) joint collateral ligament sprains should not be overtreated. First-degree sprains may require a brief period of protection, usually consisting of buddy taping for 2-3 weeks. Second-degree sprains are immobilized in mid flexion for 3 weeks. Finger MCP joint hyperextension injuries may be treated by gently flexing the proximal phalanx and immobilizing the MCP joint in 30° of flexion for 2-3 weeks. A dorsal extension-block splint protects the healing volar plate while allowing active flexion of the finger. Early protected motion minimizes postinjury stiffness. Thumb MCP joint hyperextension injuries ("locked MCP joint") are immobilized in 20° MCP joint flexion for 3 weeks.

Renal agenesis
Renal agenesis samer kareem 6,186 Views • 2 years ago

Renal agenesis is a condition in which a newborn is missing one or both kidneys. Unilateral renal agenesis (URA) is the absence of one kidney. Bilateral renal agenesis (BRA) is the absence of both kidneys. Both types of renal agenesis occur in fewer than 1 percent of births annually, according to the March of Dimes. Fewer than 1 in every 1,000 newborns has URA. BRA is much rarer, occurring in about 1 in every 3,000 births.

Most people start smoking when they are in their teens and are addicted by the time they reach adulthood. Some have tried to quit but have returned to cigarettes because smoking is such a strong addiction. It is a habit that is very difficult to break. There are many different reasons why people smoke.

Diprosopus: Rare condition disorder
Diprosopus: Rare condition disorder Alicia Berger 2,779 Views • 2 years ago

Rare condition disorder known as Diprosopus, also known as craniofacial duplication. Diprosopus is a congenital defect also known as craniofacial duplication. The exact description of diprosopus refers to a fetus with a single trunk, normal limbs, and facial features that are duplicated to a certain degree. A less severe instance is when the fetus has a duplicated nose and the eyes are spaced far apart. In the most extreme instances, the entire face is duplicated, hence the name diprosopus, which is Greek for two-faced. Fetuses with diprosopus often also lack brains (anencephaly), have neural tube defects, or heart malformations. In some cases, if the brain is formed, it may have duplicated structures. Most infants with diprosopus are stillborn and there are fewer than fifty cases documented since 1864.

The superior vena cava is a major vein in a person's body. It carries blood from the head, neck, upper chest, and arms to the heart. Superior vena cava syndrome (SVCS) occurs when a person's superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS.
