Stages of Labor
Stages of Labor samer kareem 22,310 Views • 2 years ago

Early labour contractions usually feel like period pain, or you might experience a lower backache at 20 to 30 minute intervals. Sometimes these pains radiate from back to front, or vice versa. There's no need to start timing the contractions straight away – if they are mild contractions, ignore them. The first stage of labor is the longest and involves three phases: Early Labor Phase –The time of the onset of labor until the cervix is dilated to 3 cm. Active Labor Phase – Continues from 3 cm. until the cervix is dilated to 7 cm. Transition Phase – Continues from 7 cm. until the cervix is fully dilated to 10 cm.

Dr. Glenn Barnhart explains the symptoms of mitral valve regurgitation such as becoming short of breath. There are five structures of the mitral valve: annulus, leaflet tissue, chordae tendineae, papillary muscles, and left ventricle. All of these are taken into consideration when the mitral valve is leaking and not working right. There are four degrees of mitral valve regurgitation: mild, moderate, moderately severe,.

Syringomyelia
Syringomyelia samer kareem 3,614 Views • 2 years ago

Syringomyelia (sih-ring-go-my-E-lee-uh) is the development of a fluid-filled cyst (syrinx) within your spinal cord. Over time, the cyst may enlarge, damaging your spinal cord and causing pain, weakness and stiffness, among other symptoms. Syringomyelia has several possible causes, though the majority of cases are associated with a condition in which brain tissue protrudes into your spinal canal (Chiari malformation). Other causes of syringomyelia include spinal cord tumors, spinal cord injuries and damage caused by inflammation around your spinal cord. If syringomyelia isn't causing any problems, monitoring the condition may be all that's necessary. But if you're bothered by symptoms, you may need surgery.

Part 2: Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hype
Part 2: Translational Neuroscience of Excessive Daytime Sleepiness (EDS), Fatigue and Hype Mohammad Torabi Nami 8,897 Views • 2 years ago

Sleepiness, tiredness and fatigue are complaints which must be thoroughly analyzed to eliminate blur and ambiguity.
Physiological sleepiness (“sleep pressure”) increases while being awake and additionally underlies the circadian rhythm with a lower threshold to fall asleep during night time.
Excessive daytime sleepiness (EDS) is considered normal only after sleep deprivation. Clinically, EDS manifests by frequents daytime napping and/or reduced alertness with automatic behavior or - in its extreme form - in recurrent attacks of sudden, uncontrollable compulsion to sleep also in inappropriate situations (= “sleep attacks”).
EDS is “objectively” addressed by measuring the mean sleep latency to four to five nap opportunities throughout the day using the multiple sleep latency test (MSLT) or the maintenance of wakefulness test (MWT).
EDS denotes both, a ready entrance into sleep as well as difficulty in staying awake during daytime or accordingly in inappropriate situations. These two partially independent aspects of EDS are separately assessed by the “passive” MSLT and the “active” MWT respectively.
For that reason the MSLT and MWT only weakly correlate with each other when tested over a broad range of patients with EDS. It is important to keep in mind, that these tests are importantly influenced by a great variety of factors such as mood, anxiety, and motivation.
“Vigilance” comprises wakefulness, alertness and attention and therefore is more than just the reciprocal to sleepiness. Cognitive performance tasks such as Steer Clear Reaction Time Test (SCRTT) or driving simulators require the complete integrity of vigilance to achieve normal results. Hypersomnia is usually broadly defined as the combination of abnormally prolonged night-time sleep (regularly >10 h) with EDS during ≥1 months.
On the other hand, the term hypersomnia has also been used in a narrower scene for the isolated abnormality of a prolonged night-time sleep need (>10 h). “Tiredness”, also in colloquial language often used for sleepiness, in a broader sense also describes the feeling of lack of energy, motivation and initiative.

These patients seek rest rather than sleep. They often cannot fall asleep when given the opportunity in spite of feeling tired, and hence, in an MSLT, do not show an abnormally short sleep latency. Furthermore, tiredness (and fatigue) as opposed to sleepiness has a mental (“central”) and physiological (bodily or “peripheral”) component, which the patients can readily distinguish. Patients with insomnia, mild sleep apnea syndrome, or depression rather suffer from mental tiredness than sleepiness during the day.
The simple subjective self-assessment using the Epworth Sleepiness Scale (ESS) quite reliably differentiates between sleepiness and mental tiredness (without sleepiness), which makes it a widely used test. The term “fatigue” is also heterogeneously used.
In physiology the “fatigue” implied a “time on task performance decrement” to describe decreasing muscle force during a sustained physical effort. In clinical medicine one distinguishes physical (“peripheral”) from mental (“central”) fatigue and the term usually denotes a chronic and more abnormal situation than tiredness.
In a broad sense “fatigue” implies a deficiency in coping satisfactorily with mental and physical work load. The chronic fatigue syndrome entails both mental as well as a physical fatigue (so called “leaden paralysis” of limbs). Depressive states are often associated with insomnia and fatigue, but there are also cases with hypersomnia rather than insomnia ( non organic hypersomnia , “atypical depression” or “hypersomnolent depression”)
Sometimes these patients have a tendency to spend much of the day lying in the bed without actually sleeping (so called clinophilia). The basic and clinical aspects of fatigu

What Panic Attacks Feel Like
What Panic Attacks Feel Like samer kareem 1,570 Views • 2 years ago

Panic attacks involve sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. People experiencing a panic attack may believe they are having a heart attack or they are dying or going crazy. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms:

Wrist ganglion aspiration
Wrist ganglion aspiration samer kareem 19,465 Views • 2 years ago

A nonsurgical method of treating a ganglion is to drain the fluid from (aspirate) the ganglion sac. Your doctor can do this in the office using the following procedure: The ganglion area is cleaned with an antiseptic solution. A local anesthetic is injected into the ganglion area to numb the area. When the area is numb, the ganglion sac is punctured with a sterile needle. The fluid is drawn out of the ganglion sac. The ganglion collapses. A bandage and, in some cases, a splint are used for a few days to limit movement and prevent the ganglion sac from filling again. Treating a ganglion by draining the fluid with a needle may not work because the ganglion sac remains intact and can fill again, causing the ganglion to return. For this reason, your doctor may puncture the sac with the needle 3 or 4 times so the sac will collapse completely. Even then, the ganglion is likely to come back.

Surgical Options for Epilepsy
Surgical Options for Epilepsy samer kareem 1,327 Views • 2 years ago

Surgery is an elective procedure done in people who have had extensive testing to decide if they are potential candidates. The following criteria are considered when determining if a person may be a good candidate for surgery. Person has failed adequate trials of two first-line seizure medicines (ones that are commonly effective in controlling the type of seizures the person is experiencing) and one combination of at least two drugs. A trial of a medication is considered adequate when it has been increased gradually to the maximum dosage that does not cause serious side effects. If the person has frequent seizures, any improvement will be obvious after a short time. If the seizures generally occur far apart, however, it may take months to determine whether a medication is helping. At some epilepsy centers, patients are offered additional conventional or experimental medications before surgery is considered. But research suggests that each time a trial of medication fails to control a person's seizures, it becomes less likely that a different medicine or combination will be successful. Since uncontrolled seizures present serious physical risks and social and psychological consequences, the trend these days is to proceed with surgery much sooner than in the past if it seems appropriate for that person.
