Lumbar puncture is a common emergency department procedure used to obtain information about the cerebrospinal fluid (CSF) for diagnostic and, less commonly, therapeutic reasons. Please refer to the full article on Lumbar Puncture for more details on the lumbar puncture procedure. Lumbar puncture is typically performed via “blind” surface landmark guidance. The surface landmark technique is reported to be successful in a high percentage of attempted lumbar punctures; however, surface landmark identification of underlying structures has been shown to be accurate only 30% of the time. [1] Unsuccessful identification of proper landmarks often leads to increased difficulty in obtaining CSF, if the procedure is performed, and a higher rate of complications. Few alternatives are available in these cases. If available, fluoroscopic-guided lumbar puncture may be performed. If not, treatment is sometimes initiated empirically without obtaining CSF. Disadvantages of using fluoroscopy include limited availability or necessary transport of the patient outside of the emergency department, inability to directly visualize the spinal canal, and inherent radiation exposure
urgical management of proximal humerus fractures may be categorized either according to fracture type (eg, Neer type, anatomic type, greater tuberosity, surgical neck, anatomic neck, articular surface, lesser tuberosity fragments) or according to method of fixation (eg, closed reduction with no fixation, percutaneous fixation, open reduction with internal fixation [ORIF], humeral head replacement associated with tuberosity fixation

Lo Que Todos Necesitan Saber Sobre La Presión Arterial Alta
Si le han dicho que tiene presión arterial alta, usted puede decir, "Pero me siento muy bien!" Esto se debe a que la hipertensión o la presión arterial alta no tiene síntomas visibles. Es por eso que se la describe a menudo como el "asesino silencioso". No hay achaques o limitaciones físicas sólo porque tiene la presión arterial alta. Entonces, por qué siquiera preocuparse?
La hipertensión afecta a uno de cada tres adultos estadounidenses, y muchas de estas personas ni siquiera saben que la tienen. Además, aquellos con presión arterial alta tienen también un mayor riesgo de tener el colesterol alto.

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.
Osteoporosis is a disease in which bones become brittle and fragile due to low bone mass and bone tissue loss. It's the most common type of bone disease, according to the National Institutes of Health (NIH), and increases your risk of fractures, particularly of the hips, spine, and wrists. Prevalence In the United States, nearly 54 million people ages 50 and older were living with osteoporosis or osteopenia (low bone mass ) in 2010, according to a 2014 article in the Journal of Bone and Mineral Research. More specifically, 10.2 million adults had osteoporosis, and 43.4 million adults had osteopenia, which puts a person at high risk for osteoporosis.
A seizure occurs when there’s abnormal electrical activity in the brain. Seizures may go virtually unnoticed. Or, in severe cases, they may produce a change or loss of consciousness and involuntary muscle spasms called convulsions. Seizures usually come on suddenly and vary in duration and severity. A seizure may be a one-time event, or you may have seizures repeatedly. Recurrent seizures are called epilepsy, or a seizure disorder. Less than one in 10 people who has a seizure develops epilepsy. Experts classify seizures into two general categories and many subtypes based on the pattern of the attack. Generalized seizures involve both sides of the brain from the start of the attack. Common subtypes include tonic-clonic (grand mal) and absence seizures (petit mal). Febrile and infantile spasms are two types of generalized seizures that occur almost exclusively in young children. Partial (or focal) seizures are the second major seizure type. These begin in a specific area of the brain and may be contained there. Or they may spread to the entire brain. With simple partial seizures, the person remains conscious. Complex partial seizures involve impaired consciousness. What Causes Seizures? Often the cause of a seizure is unknown. Many conditions can provoke seizures, including: Stroke Brain tumors Head injuries Electrolyte imbalance Very low blood sugar Repetitive sounds or flashing lights, such as in video games Medications, such as antipsychotics and some asthma drugs Withdrawal from medications, such as Xanax, narcotics, or alcohol Use of drugs such as cocaine and heroin Cancer Brain infections, such as meningitis
Goiter treatment depends on the size of the goiter, your signs and symptoms, and the underlying cause. Your doctor may recommend: Observation. If your goiter is small and doesn't cause problems, and your thyroid is functioning normally, your doctor may suggest a wait-and-see approach. Medications. If you have hypothyroidism, thyroid hormone replacement with levothyroxine (Levoxyl, Synthroid, Tirosint) will resolve the symptoms of hypothyroidism as well as slow the release of thyroid-stimulating hormone from your pituitary gland, often decreasing the size of the goiter. For inflammation of your thyroid gland, your doctor may suggest aspirin or a corticosteroid medication to treat the inflammation. For goiters associated with hyperthyroidism, you may need medications to normalize hormone levels. Surgery. Removing all or part of your thyroid gland (total or partial thyroidectomy) is an option if you have a large goiter that is uncomfortable or causes difficulty breathing or swallowing, or in some cases, if you have a nodular goiter causing hyperthyroidism.
