Normal Heart Sounds
Normal Heart Sounds Scott 67,386 Views • 2 years ago

Normal Heart Sounds With the aid of a stethoscope you can hear the characteristic sounds of the normal heartbeat, typically described as a "lub-dub." These sounds are produced by the closure of the heart valves. The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall. This "dub" sound is typically heard as a sharp snap because the semilunar valves tend to close much more rapidly than the AV valves. Because diastole occupies more time than systole, a brief pause occurs after the second heart sound when the heart is beating at a normal rate. Therefore, the pattern that one hears is one of: "lub-dub" pause, "lub-dub" pause, and so on. Sometimes, especially in young normal individuals, a third heart sound can be heard. This sound is produced by the very rapid influx of blood into the partially filled ventricle. It is typically very faint and as such difficult to hear.

Fundus Exam Eye Video

With an Ophthalmoscope, light is shone into the eye and the retina and the optic nerve is examined. This is called as Examination of the Fundus. This is what the eye-doctor sees when he peeps into your eye! Through the transparent cornea, into the dark interior. The Fundus Exam When he looks into the eye with the Ophthalmoscope, he sees a orange glowing interior. That is the retina. The retina is actually transparent. It appears bright because of blood vessels in the choroid layer below. It is like looking at your ear against the bright sunlight. The yellow circle is the Optic Nerve, the cable of vision! A red, shiny dot attracts attention. That is the macula. If indicated, the exam of periphery of the retina is done with an Indirect ophthalmoscope. The ophthalmologist wears this instrument on the head and focuses the light into the eye with a lens held in his hand. This is usually done in a dark room.

University Hospitals Neurological Institute will host a live webcast to demonstrate the removal of a brain tumor that doctors believe is causing epileptic seizures in a middle-aged man.

An MRI showed what appears to be a glioma (tumor) near a part of the brain that controls muscle movement, called the motor strip. Studies have shown that complete removal can cure the seizures and improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because it's difficult to determine where tumor ends and normal brain begins.

Pelvic Floor Exercise & Bladder Scans
Pelvic Floor Exercise & Bladder Scans Surgeon 23,821 Views • 2 years ago

Surgery to treat men with prostate cancer is often followed by months of difficulty controlling urine flow, a condition known as urinary incontinence. But new research suggests that this problem may go away more quickly if the men perform certain exercises to strengthen their pelvic floor muscles.
Researchers from the Kaiser Permanente Medical Center in Los Angeles, California, found that men who were taught how to perform pelvic floor exercises before and after surgery were more likely to have regained continence three months later.

Men Doing Pelvic Exercises Recover Earlier

In the current study, the researchers randomly assigned 38 men scheduled for radical prostatectomy to either a treatment group or a control group. The men in the treatment group were referred to a physical therapist. They were instructed how to do Pelvic Floor Exercises both before and after surgery, using biofeedback to ensure they were using the proper muscles. The control group did not receive any formal instruction. All of the men completed questionnaires regarding bladder function at regular intervals over the next year.
Overall, 82% of the patients had regained continence (defined as not needing to use any absorbent pads) by the end of the year, including about equal numbers in both groups. But on average the men who had been educated about Pelvic exercises regained continence about one month earlier than those in the control group (at 12 weeks vs. 16 weeks).
Most of the men who did not regain continence within a year were still using at least three absorbent pads a day, indicating continued severe incontinence. The study authors explained that these men probably had extensive damage to the bladder sphincter or severe dysfunction of the bladder after surgery, and the exercises alone were unable to compensate for this.
But the exercises seemed to be effective. Pelvic floor exercise and education initiated prior to surgery is an effective noninvasive intervention useful for improving early return of urinary continence, the authors concluded. It would certainly have a positive impact on our patients undergoing radical prostatectomy in an effort to improve quality of life after major urological surgery.

The results of the study were published in the Journal of Urology (Vol. 170, No. 1: 130-133)
