Left atrial myxoma
Left atrial myxoma samer kareem 7,096 Views • 2 years ago

Symptoms range from nonspecific and constitutional to sudden cardiac death. [18] In about 20% of cases, myxomas may be asymptomatic and discovered as an incidental finding. Signs and symptoms of mitral stenosis, endocarditis, mitral regurgitation, and collagen vascular disease can simulate those of atrial myxoma. A high index of suspicion aids in diagnosis. Symptoms of left-sided heart failure include the following: Dyspnea on exertion (75%) that may progress to orthopnea, paroxysmal nocturnal dyspnea, and pulmonary edema is observed. [19, 20] Symptoms are caused by obstruction at the mitral valve orifice. Valve damage may result in mitral regurgitation.

The lumps may be hard or rubbery and can appear as a single breast lump that may be large or small. Fibrocystic changes also can appear as thickening of the breast tissue. Fibrocystic changes can occur in one or both breasts and are the most common cause of benign breast lumps in women age 35 to 50.

Chronic myeloid leukaemia: diagnosis and management
Chronic myeloid leukaemia: diagnosis and management samer kareem 1,662 Views • 2 years ago

Chronic myeloid leukaemia is a common malignancy worldwide. We have come a long way from the limited treatment options and survival in this condition. Today, CML is a treatable malignancy with more than 80% patients surviving beyond 10 years after diagnosis, in absence of complications. This presentation deals with the definition, diagnostic criteria of chronic phase, accelerated and blastic phase (MD Anderson cancer centre, International bone marrow transplant registry and the WHO for the latter two) and management (first and second generation tyrosine kinase inhibitors) of this condition. Finally, a stepwise approach to chronic myeloid leukaemia is also presented including the definitive modality of treatment, allogeneic stem cell transplantation.

Stapling is used to treat prolapsed hemorrhoids. A surgical staple fixes the prolapsed hemorrhoid back into place inside your rectum and cuts off the blood supply so that the tissue will shrink and be reabsorbed. Stapling recovery takes less time and is less painful than recovery from a hemorrhoidectomy.

If you have a lung disease, a type of surgery called a lobectomy is one treatment option your doctor may suggest. Your lungs are made up of five sections called lobes. You have three in your right lung and two in your left. A lobectomy removes one of these lobes. After the surgery, your healthy tissue makes up for the missing section, so your lungs should work as well or better than they did before.

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 8,904 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

Acute aortic thrombosis
Acute aortic thrombosis samer kareem 1,949 Views • 2 years ago

The increased risk of thrombosis in patients with active cancer has multiple causes. Acute thrombosis of the aorta is an exceedingly rare but potentially devastating complication in patients with cancer receiving cisplatin-based chemotherapy. Prompt diagnosis and definitive treatment are imperative to decrease morbidity and mortality. Early diagnosis is difficult because initial presentation is often nonspecific, requiring a high degree of clinical suspicion. We report 4 cases of acute thrombosis of the abdominal aorta in patients with cancer receiving cisplatin-based chemotherapy. We review the clinical aspects, recommended investigation, and treatment of this potentially fatal complication.

Frostbite, drainage
Frostbite, drainage samer kareem 19,124 Views • 2 years ago

Frostbite is an injury caused by freezing of the skin and underlying tissues. First your skin becomes very cold and red, then numb, hard and pale. Frostbite is most common on the fingers, toes, nose, ears, cheeks and chin. Exposed skin in cold, windy weather is most vulnerable to frostbite. But frostbite can occur on skin covered by gloves or other clothing. Frostnip, the first stage of frostbite, doesn't cause permanent skin damage. You can treat very mild frostbite with first-aid measures, including rewarming your skin. All other frostbite requires medical attention because it can damage skin, tissues, muscle and bones. Possible complications of severe frostbite include infection and nerve damage.

A facet joint injection is a relatively simple, straightforward procedure, and is usually performed in an office based procedure suite or in an ambulatory surgical center. As with many spinal injections, facet joint injections are best performed using fluoroscopy (live X-ray) for guidance to properly target and place the needle (and to help avoid nerve injury or other injury).
