Why Do We Vomit? samer kareem 5,282 Views • 2 years ago

The timing of the nausea or vomiting can indicate the cause.

Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.

Thyroid Clinical Examination
Thyroid Clinical Examination samer kareem 19,328 Views • 2 years ago

The examination consists of three portions: Inspection, Palpation, and Synthesis of data from these techniques In addition to palpating for size, also note the gland texture, mobility, tenderness and the presence of nodules. Inspection Inspection: Anterior Approach The patient should be seated or standing in a comfortable position with the neck in a neutral or slightly extended position. Cross-lighting increases shadows, improving the detection of masses. To enhance visualization of the thyroid, you can: Extending the neck, which stretches overlying tissues Have the patient swallow a sip of water, watching for the upward movement of the thyroid gland. quicktime video 251KB video demo from Return to the Bedside Inspection: Lateral Approach After completing anterior inspection of the thyroid, observe the neck from the side. Estimate the smooth, straight contour from the cricoid cartilage to the suprasternal notch. Measure any prominence beyond this imagined contour, using a ruler placed in the area of prominence. Palpation Note: There is no data comparing palpation using the anterior approach to the posterior approach so examiners should use the approach that they find most comfortable. Palpation: Anterior Approach placement of hands for palpatation of thyroid in anterior approach The patient is examined in the seated or standing position. Attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Use one hand to slightly retract the sternocleidomastoid muscle while using the other to palpate the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland. quicktime video 454KB video demo from Return to the Bedside. Palpation: Posterior Approach placement of hands for palpatation of thyroid in posterior approach The patient is examined in the seated or standing position. Standing behind the patient, attempt to locate the thyroid isthmus by palpating between the cricoid cartilage and the suprasternal notch. Move your hands laterally to try to feel under the sternocleidomstoids for the fullness of the thyroid. Have the patient swallow a sip of water as you palpate, feeling for the upward movement of the thyroid gland.

Emergency Pericardiocentesis
Emergency Pericardiocentesis samer kareem 7,805 Views • 2 years ago

Pericardiocentesis is the aspiration of fluid from the pericardial space that surrounds the heart. This procedure can be life saving in patients with cardiac tamponade, even when it complicates acute type A aortic dissection and when cardiothoracic surgery is not available. [1] Cardiac tamponade is a time sensitive, life-threatening condition that requires prompt diagnosis and management. Historically, the diagnosis of cardiac tamponade has been based on clinical findings. Claude Beck, a cardiovascular surgeon, described 2 triads of clinical findings that he found associated with acute and chronic cardiac tamponade. The first of these triads consisted of hypotension, an increased venous pressure, and a quiet heart. It has come to be recognized as Beck's triad, a collection of findings most commonly produced by acute intrapericardial hemorrhage. Subsequent studies have shown that these classic findings are observed in only a minority of patients with cardiac tamponade. [2] The detection of pericardial fluid has been facilitated by the development and continued improvement of echocardiography. [3] Cardiac ultrasound is now accepted as the criterion standard imaging modality for the assessment of pericardial effusions and the dynamic findings consistent with cardiac tamponade. With echocardiography, the location of the effusion can be identified, the size can be estimated (small, medium, or large), and the hemodynamic effects can be examined by assessing for abnormal septal motion, right atrial or right ventricular inversion, and decreased respiratory variation of the diameter of the inferior vena cava.

Best Timing and Sexual positions to get pregnant fast
Best Timing and Sexual positions to get pregnant fast samer kareem 2,384 Views • 2 years ago

You may have heard that some positions, such as your partner on top (missionary position), are better than others for getting pregnant. In fact, there's no evidence to back these theories up. Experts just haven't done the research yet. What experts have done, though, is use scanning to show what's going on inside when you're doing the deed. The research looked at two positions: the missionary position and doggy style. (Doggy style being when you're on all fours, and your partner enters you from behind). Common sense tells us that these positions allow for deep penetration. This means that they're more likely to place sperm right next to your cervix (the opening of your uterus). The scans confirm that the tip of the penis reaches the areas between the cervix and vaginal walls in both of these positions. The missionary position allows the penis to reach the area at the front of the cervix. The rear entry position reaches the area at back of the cervix. It's amazing what some experts spend their time doing, isn't it! Other positions, such as standing up, or woman on top, may be just as good for getting sperm right next to the cervix. We just don't know yet. http://www.babycentre.co.uk/sex-for-getting-pregnant#ixzz4XKnPLbxL

Narcolepsy
Narcolepsy samer kareem 10,774 Views • 2 years ago

Narcolepsy is a chronic sleep disorder characterized by overwhelming daytime drowsiness and sudden attacks of sleep. People with narcolepsy often find it difficult to stay awake for long periods of time, regardless of the circumstances. Narcolepsy can cause serious disruptions in your daily routine. Sometimes, narcolepsy can be accompanied by a sudden loss of muscle tone (cataplexy) that leads to weakness and loss of muscle control. Cataplexy is often triggered by a strong emotion, most commonly laughter. Narcolepsy is a chronic condition for which there's no cure. However, medications and lifestyle changes can help you manage the symptoms. Support from others — family, friends, employer, teachers — can help you cope with narcolepsy.

St. John's Wort
St. John's Wort samer kareem 4,492 Views • 2 years ago

St. John's wort (Hypericum perforatum) is an over-the-counter herbal supplement used for its antidepressant, anti-inflammatory, and wound-healing properties. Although it has been prescribed in Europe for mild to moderate depression, negative clinical trials and multiple reports of adverse drug interactions have raised concern about its use. St. John's wort induces various P450 isozymes (CYP 1A2, 2C19, 2C9, and 3A4) and P-glycoprotein systems. Drug interactions with the herbal product can lead to treatment failures with many medications, including hormonal contraceptives, antiretrovirals, immunosuppressive agents, narcotics, anticoagulants, and antifungals. There is also a risk for serotonin syndrome when St. John's wort is used in combination with other serotonergic antidepressants. The lack of strict regulation of herbal products that results in variable quality and content (unknown toxic ingredients or inactive ingredients) is also a concern.
