CROUP
CROUP samer kareem 1,654 Views • 3 years ago

Croup refers to an infection of the upper airway, which obstructs breathing and causes a characteristic barking cough. The cough and other symptoms of croup are the result of swelling around the vocal cords (larynx), windpipe (trachea) and bronchial tubes (bronchi). When a cough forces air through this narrowed passage, the swollen vocal cords produce a noise similar to a seal barking. Likewise, taking a breath often produces a high-pitched whistling sound (stridor). Croup typically occurs in younger children. Croup usually isn't serious and most cases can be treated at home.

In a small but promising Phase II clinical trial of breast cancer treatment, cryoablation killed 25 early-stage tumors in 13 women. The tumors ranged in size from .5 cm (very small) to 5.8 cm (very large), with an average size of 1.7cm. Patients were first given a local anesthesia with mild sedation before physicians used ultrasound with or without computed tomography (CT) imaging to guide needle-like probes to deliver very low temperature gas to the tumor site. The ultra-cold gas forms a ball of ice around the probe tip, then expands and destroys surrounding tumor cells. A harmless saline solution was first injected into the chest wall and skin of the breast to protect the tissue surrounding the tumor from the freezing effects. Patients experienced very little pain and most healed completely within six months with no complications and with little or no scarring. The cryotherapy margins of each participant were biopsied immediately after the procedures, and all were negative, with no evidence of cancerous tissue. All 13 patients were without recurrence at an average of 18 months and up to five years following the procedure. These results are promising, but larger studies with lengthier follow-up are needed to determine whether cryotherapy as effective as lumpectomy. A study involving cryoablation of mouse tumors at the University of Michigan Comprehensive Cancer Center found that the freezing procedure also works like a vaccine, boosting the immune system to reduce the likelihood of recurrence. Just how quickly the tumor was frozen made a difference: a 30-second freeze killed tumors and also boosted the immune system, inhibiting metastases to the lungs. A slower freezing lasting several minutes destroyed tumors just as effectively, but actually suppressed the immune system, resulting in greater metastases to the lungs.

How to Prevent STDs
How to Prevent STDs samer kareem 1,909 Views • 3 years ago

Preventing Sexually Transmitted Diseases A sexually transmitted disease (STD) is an infection that is spread during sexual contact with another person. This includes touching, since some STDs can be spread from skin-to-skin contact. In general, STDs are highly preventable. Almost 20 million new STDs are diagnosed each year in the United States, according to the Centers for Disease Control and Prevention (CDC). However, a large number of those infections could be avoided if people made different decisions about their sexual health. The only guaranteed method to prevent STDs is to abstain from all sexual contact. This may not a practical solution for everyone. Fortunately, there are steps people can take to limit their risk of exposure.

Factitious disorder is the term used to describe a pattern of behavior centered on the exaggeration or outright falsifications of one’s own health problems or health problems of others. Some people with this disorder fake or exaggerate physical problems; others fake or exaggerate psychological problems or a combination of physical and psychological problems. Factitious disorder differs from a pattern of falsified or exaggerated behavior called malingering. While malingerers make their claims out of a motivation for personal gain, people with factitious disorder have no such motivation.

Propofol Use in the ED
Propofol Use in the ED samer kareem 2,347 Views • 3 years ago

Multiple studies demonstrate the safety of propofol in pediatric EDPS. Each has identified a drop in blood pressure and transient hypoxemia as the most frequent complications. In all of the studies in which hypotension was identified there was no evidence of poor perfusion. The hypoxemia in all of these studies quickly responded to minimal intervention with no apparent lasting complications. Although these were pediatric studies, the results were very similar to ours in complication rates and sedation times. Our study did not demonstrate the frequency of decreased blood pressure seen in these pediatric studies but had similar hypoxemia rates.
