TSK: This happens to students/residents ALL the time...

  • Cranquis: Well, Mrs. Perjure, my PA student tells me that your mysterious rash just showed up suddenly yesterday?
  • Patient: YES AND IT IS REALLY ITCHY!
  • Cranquis: Well even though you told the student that you haven't been around any plants lately, the rash really looks like poison ivy...
  • Patient: OH BUT I HAVE BEEN AROUND PLANTS, I SPENT ALL WEEKEND PULLING OUT WEEDS FROM UNDER THE PORCH!
  • PA Student: *sputtering helplessly*
medicalschool: Sleep Quality May Be Tied to Covert Brain Wave A type of brain activity known as an alpha wave emanates from the back of the head when a person is awake but relaxing with eyes closed. Scientists used to think that the wave was subdued and disappeared as a person fell deeper and deeper into sleep. But the alpha wave doesn’t disappear; it just goes undercover during sleep, researchers report online March 3 in PLoS One.

Sleep Quality May Be Tied to Covert Brain Wave

A type of brain activity known as an alpha wave emanates from the back of the head when a person is awake but relaxing with eyes closed. Scientists used to think that the wave was subdued and disappeared as a person fell deeper and deeper into sleep. But the alpha wave doesn’t disappear; it just goes undercover during sleep, researchers report online March 3 in PLoS One. The covert alpha wave may help determine how deeply people sleep and how much noise is needed to rouse a sleeper.

Most are familiar with simple Mendelian inheritance: One copy, or allele, of a particular gene comes from your mother, and the other from your father. If one gene is defective, usually, if you have an effective copy from the other parent, you’re asymptomatic - and it doesn’t matter which allele comes from which parent. But what happens when Mendelian genetics gets thrown to the winds?

Prader-Willi Syndrome and Angelman Syndrome are twin examples of this phenomenon in action. Contrary to normal Mendelian, these two follow quite a strange pattern of inheritance: If the defective gene comes from the father, the offspring has Prader-Willi Syndrome, and the maternal allele is silenced; and if the defective gene comes from the mother, the child has Angelman Syndrome, and the paternal allele is silenced. These two syndromes are classic examples of genomic imprinting, and come with varying sets of symptoms and severity.

Prader-Willi Syndrome tends to be more severe than Angelman Syndrome, and is characterised by low muscle tone, short stature, incomplete sexual development, cognitive disabilities, problem behaviours, and a chronic feeling of hunger that can lead to excessive eating and life-threatening obesity. Angelman Syndrome is characterised by developmental impairment, speech delay, balance disorder, and “behavioural uniqueness” - usually apparent through frequent laughter or smiling and an overall excessively happy demeanor.

Breast within a breast sign - refers to the common mammographic appearance of breast hamartomas (fibroadenolipomas). Since these benign lesions are well-circumscribed and contain a mixture of fibrous, glandular and fatty tissue (just like normal breast), it is not surprising that the appear very much like a second breast sitting within the actual breast.
