A spermatocele (SPUR-muh-toe-seel) is an abnormal sac (cyst) that develops in the epididymis — the small, coiled tube located on the upper testicle that collects and transports sperm. Noncancerous and generally painless, a spermatocele usually is filled with milky or clear fluid that might contain sperm. The exact cause of spermatoceles is unknown but might be due to a blockage in one of the tubes that transports sperm. Spermatoceles, sometimes called spermatic cysts, are common. They typically don't reduce fertility or require treatment. If a spermatocele grows large enough to cause discomfort, your doctor might suggest surgery.

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.

Testing for the four features of Gerstmann Syndrome in this patient with two separate left sided strokes (left frontoparietal ischaemic stroke followed by left posterior parietal haemorrhagic stroke). He exhibits (i) acalculia, (ii) agraphia, (iii) left-right disorientation, and (iv) finger agnosia. Complicating the issue is his obvious nonfluent aphasia (expressive dysphasia) with paraphasic errors (replacing words with associated words (e.g. says 'fork' instead of 'spoon')) and some comprehension issues.

Minimally invasive open thyroidectomy (MIT) is similar to conventional thyroidectomy in its surgical approach. The major difference is the length of the neck incision. A smaller incision improves cosmesis and reduces discomfort. Typically, a skin incision less than 6 cm is considered minimally invasive. The remainder of the procedure is exactly the same as is used in conventional thyroidectomy. Adaptations to this technique include transection rather than lateral retraction of the strap muscles (the Sofferman technique). [1]

Beating heart or "off pump" coronary artery surgery is the latest revolution in the management coronary disease. It is being embraced world-wide by increasing numbers of surgeons.

Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The most common symptoms of medulloblastoma include behavioral changes, changes in appetite, symptoms of increased pressure on the brain (eg, headache, nausea, vomiting, and drowsiness, as well as problems with coordination). Unusual eye movements may also occur. Like many tumor types, the exact cause of medulloblastoma is not known. However, scientists are making significant strides in understanding its biology. Changes have been identified in genes and chromosomes (the cell’s DNA blueprints) that may play a role in the development of this tumor. There are also a few rare, genetic health syndromes that are associated with increased risk for developing this tumor.

A grand mal seizure causes a loss of consciousness and violent muscle contractions. It's the type of seizure most people picture when they think about seizures. A grand mal seizure — also known as a generalized tonic-clonic seizure — is caused by abnormal electrical activity throughout the brain. Usually, a grand mal seizure is caused by epilepsy. But sometimes, this type of seizure can be triggered by other health problems, such as extremely low blood sugar, a high fever or a stroke. Many people who have a grand mal seizure never have another one and don't need treatment. But someone who has recurrent seizures may need treatment with daily anti-seizure medications to control and prevent future grand mal seizures
