A hematoma is a collection of blood outside of a blood vessel. There are several types of hematomas and they are often described based on their location. Examples of hematomas include subdural, spinal, under the finger or toenail bed (subungual), ear, and liver (hepatic). Some causes of hematomas are as pelvic bone fractures, fingernail injuries (subungual), bumps, passing blood clots, blood clot in the leg (DVT), blood cancers, and excessive alcohol use. Symptoms of hematomas depend upon their location and whether adjacent structures are affected by the inflammation and swelling associated with the bleeding and may include

Urinary incontinence isn't a disease, it's a symptom. It can be caused by everyday habits, underlying medical conditions or physical problems. A thorough evaluation by your doctor can help determine what's behind your incontinence. Temporary urinary incontinence Certain drinks, foods and medications can act as diuretics — stimulating your bladder and increasing your volume of urine. They include: Alcohol Caffeine Decaffeinated tea and coffee Carbonated drinks Artificial sweeteners Corn syrup Foods that are high in spice, sugar or acid, especially citrus fruits Heart and blood pressure medications, sedatives, and muscle relaxants Large doses of vitamins B or C Urinary incontinence also may be caused by an easily treatable medical condition, such as: Urinary tract infection. Infections can irritate your bladder, causing you to have strong urges to urinate, and sometimes incontinence. Other signs and symptoms of urinary tract infection include a burning sensation when you urinate and foul-smelling urine. Constipation. The rectum is located near the bladder and shares many of the same nerves. Hard, compacted stool in your rectum causes these nerves to be overactive and increase urinary frequency. Persistent urinary incontinence Urinary incontinence can also be a persistent condition caused by underlying physical problems or changes, including: Pregnancy. Hormonal changes and the increased weight of the uterus can lead to stress incontinence. Childbirth. Vaginal delivery can weaken muscles needed for bladder control and also damage bladder nerves and supportive tissue, leading to a dropped (prolapsed) pelvic floor. With prolapse, the bladder, uterus, rectum or small intestine can get pushed down from the usual position and protrude into the vagina. Such protrusions can be associated with incontinence. Changes with age. Aging of the bladder muscle can decrease the bladder's capacity to store urine. Menopause. After menopause women produce less estrogen, a hormone that helps keep the lining of the bladder and urethra healthy. Deterioration of these tissues can aggravate incontinence. Hysterectomy. In women, the bladder and uterus are supported by many of the same muscles and ligaments. Any surgery that involves a woman's reproductive system, including removal of the uterus, may damage the supporting pelvic floor muscles, which can lead to incontinence. Enlarged prostate. Especially in older men, incontinence often stems from enlargement of the prostate gland, a condition known as benign prostatic hyperplasia. Prostate cancer. In men, stress incontinence or urge incontinence can be associated with untreated prostate cancer. But more often, incontinence is a side effect of treatments for prostate cancer. Obstruction. A tumor anywhere along your urinary tract can block the normal flow of urine, leading to overflow incontinence. Urinary stones — hard, stone-like masses that form in the bladder — sometimes cause urine leakage. Neurological disorders. Multiple sclerosis, Parkinson's disease, stroke, a brain tumor or a spinal injury can interfere with nerve signals involved in bladder control, causing urinary incontinence.
This video is really sad. You can literally watch this man dying. He was shot in the chest and rushed to the emergency room. His heart has stopped beating or has arrested. As a last resort, surgeons did an extreme procedure called an open thoracotomy which is that crazy tool you see there that basically splits the ribs open and allows easy open access to the heart. They did this so they could give him a cardiac massage. A cardiac massage is when surgeons are manually trying to pump the heart after it has stopped working on its own (cardiac arrest). Unfortunately he lost so much blood from his gun shot wound and he was pronounced dead. There are cases of patients surviving after having this kind of invasive resuscitation but it is rare.
This patient presented to the ER for umbilical pain and had a history of umbilical hernia. He was concerned about the possibility of incarceration of the hernia.
In this video we explain how the clinical exam helps to differentiate a simple painful hernia from an incarcerated one.
***Thanks to the patient for sharing his history and exam with YouTube world***

The male orgasm is a common subject but usually misunderstood at the same time. Men are sometimes led to believe that ejaculating often is a bad thing, particularly if you masturbate. The truth is that ejaculation is important to every man due to a number of reasons. The main goal of this post is to shed some light on reasons why men need to ejaculate.
What is a mole? Many people refer to a mole as any dark spot or irregularity in the skin. Doctors use different terms. But the following types of skin marks such as these are not treated the same way moles are and are not discussed here: Birthmarks Abnormal formations of blood vessels (hemangiomas) Keratoses (benign or precancerous spots, which appear after about age 30 years)
Microsurgical bipolar cautery tonsillectomy compares favorably with traditional techniques in terms of intraoperative bleeding, postoperative pain, otalgia, and hemorrhage. This technique combines the hemostatic advantage of cautery dissection, the excellent visualization achieved by a microscope, and, with the use of a video, greatly improves the physician's ability to teach how to perform a tonsillectomy.
Norepinephrine is synthesized from dopamine by dopamine β-hydroxylase.[7] It is released from the adrenal medulla into the blood as a hormone, and is also a neurotransmitter in the central nervous system and sympathetic nervous system where it is released from noradrenergic neurons.
