Vasectomy is a minor surgical procedure wherein the vasa deferentia of a man are severed, and then tied or sealed in a manner such to prevent sperm from entering the seminal stream (ejaculate). Typically done in an outpatient setting, a traditional vasectomy involves numbing (local anesthetic) of the scrotum after which 1 (or 2) small incisions are made, allowing a surgeon to gain access to the vas deferens.

What Is a Paronychia (Nail Infection)? An infection that develops along the edge of the fingernail or toenail is called a paronychia (pear-ah-NIK-ee-ah). It is the most common hand infection and, if left untreated, can progress to a more severe infection of the entire finger or toe. Paronychia is distinguished from other infections such as onychomycosis and herpetic whitlow by its location and appearance.

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

When you’re trying to conceive a baby it is worth giving anything a go which you think will boost your chances. This includes considering that there may be better positions for getting pregnant. But it pays to bear in mind that the human race has been around for over 200,000 years and most of us were probably conceived without our ancestors investing too much thought into the mechanics. Science has proven that successful conception isn’t so much about sexual position as the frequency of sex between a fertile couple. Basically, if you want to fall pregnant, don’t use contraception and have frequent, active and enjoyable sex. Importantly, don’t stress too much about whether you’re doing it the right way. Women can, and do, conceive in any position. Nature has a way of making sure of that.

In patients age ;::25, HPV DNA testing is the preferred next step in management if the initial cytology shows ASC-US. In this method, samples are collected for both cytology and reflex HPV DNA. If cytology results are positive, HPV DNA testing is performed. If cytology results are negative, the sample for HPV DNA is discarded. HPV DNA testing along with Pap smear at 3 years is recommended if initial cytology shows ASC-US but HPV DNA testing is negative

The most reliable clinical sign to detect ascites is checking for bilateral flank dullness. If a patient with ascites is lying supine, fluid accumulates in the flank regions, leading to dullness on percussion. At the same time, the air-filled bowel loops are forced upwards by the free fluid due to buoyancy, resulting in tympanitic percussion. To locate specifically where dullness shifts to tympany, or the air-fluid level, percussion should be performed from the sides towards the middle. To confirm that the dullness is caused by ascites, ask the patient to switch to a lateral decubitus position. If ascites is present, the air-filled bowel loops will shift accordingly and remain at the surface of the fluid. As a result, the air-fluid level will shift as well. This is known as shifting dullness.

This 3D animation of brain surgery, shows how a ventriculostomy is performed, which is a neurosurgical procedure of creating a hole within a cerebral ventricle for drainage. It is most commonly performed on those with hydrocephalus, an abnormal buildup of fluid in the ventricles (cavities) deep within the brain. It's done by surgically penetrating the skull, dura mater, and brain such that the ventricular system ventricle of the brain is accessed.

When catheter drainage is temporary, it is commonly referred to as an external ventricular drain (EVD). When catheter drainage is permanent, it is usually referred to as a shunt.

There are many catheter-based ventricular shunts that are named for where they terminate, for example, a ventriculi-peritoneal shunt terminates in the peritoneal cavity, a ventriculoarterial shunt terminates within the atrium of the heart, etc. The most common entry point on the skull is called Kocher's point. An EVD ventriculostomy is done primarily to monitor the intracranial pressure as well as to drain cerebrospinal fluid (CSF), primarily, or blood to relieve pressure from the central nervous system (CNS).
