Computed tomography (CT)-guided transthoracic needle biopsy is a well-established, minimally invasive diagnostic tool for pulmonary lesions. Few large studies have been conducted on the diagnostic performance and adequacy for molecular testing of transthoracic core needle biopsy (TCNB) for small pulmonary lesions.
There are twelve cranial nerves in total. The olfactory nerve (CN I) and optic nerve (CN II) originate from the cerebrum. Cranial nerves III – XII arise from the brain stem (Figure 1). They can arise from a specific part of the brain stem (midbrain, pons or medulla), or from a junction between two parts: Midbrain – the trochlear nerve (IV) comes from the posterior side of the midbrain. It has the longest intracranial length of all the cranial nerves. Midbrain-pontine junction – oculomotor (III). Pons – trigeminal (V). Pontine-medulla junction – abducens, facial, vestibulocochlear (VI-VIII). Medulla Oblongata – posterior to the olive: glossopharyngeal, vagus, accessory (IX-XI). Anterior to the olive: hypoglossal (XII). The cranial nerves are numbered by their loca
Retinitis pigmentosa is a rare, inherited degenerative eye disease that causes severe vision impairment. Symptoms often begin in childhood. They include decreased vision at night or in low light and loss of side vision (tunnel vision). There's no effective treatment for this condition. Wearing sunglasses may help protect remaining vision.

Surgeons at St Mary's Hospital, part of Imperial College Healthcare have come up with a new surgical procedure that cures heartburn with a device called RefluxStop.
Mr Ahmed Ahmed, a consultant surgeon, says surgery should now be seen as an alternative to life-long drug treatment - as Sky's Thomas Moore reports.

What is hemodialysis and how does it work? Who needs it? How do you prepare for it? In the United States, over 30 million Americans have kidney disease, and sometimes, kidney disease progresses to kidney failure or end-stage renal disease. When this happens, you cannot survive unless you have a kidney transplant or some form of dialysis. So today we're going to talk about hemodialysis.
Your kidneys are the two kidney bean-shaped organs that are located in your lower back, or in your flanks. And the kidneys are responsible for filtering out or cleaning your blood. They get rid of excess waste, excess toxins, and excess fluids. If your kidneys stop functioning, then you develop renal failure or end-stage renal disease.
What is Hemodialysis?
Hemodialysis, or blood dialysis, is the filtering of your blood outside of your body. So, if your kidneys stop working properly, the hemodialysis acts as a substitute kidney. Now it's important to note that hemodialysis does not actually correct your own kidney function. It does not fix or treat your kidneys.
#hemodialysis #drfrita
What is The Dialyzer?
The dialyzer is actually the filter. It's the main powerhouse of the hemodialysis system, and it is what actually acts as the substitute kidney. In the dialyzer, you have these hollow fibers that run through it, and these fibers are bathed in something called dialysates, or dialysis fluid.
How Often Are Patients Treated With Hemodialysis?
Most patients who are on hemodialysis are on it between three and six hours, about three days a week, especially if they go to a center.
How Does Hemodialysis Work?
So when you are on dialysis, how does your blood get from your body to the hemodialysis machine and then back to your body? Well, it does so through tubes, and those tubes are connected to your access, and we'll talk about access in just a moment. But as far as the tubing, the tubing is connected to your body.
Types Of Hemodialysis Access
Arteriovenous Fistula or AV Fistula
The AV fistula is the gold standard as far as hemodialysis access is concerned because it gives you the most efficient hemodialysis and it is the least likely to be infected.
Arteriovenous Graft or AV Graft
The AV graft is very similar to the AV fistula in that you still have a surgically connected artery and a vein, usually in the arm, but in the case where if you have veins that are rather thin or arteries that are thin and maybe too weak in order to really give you a properly functioning, substantial AV fistula, then the vascular surgeon may opt to add an artificial material in order to make that shunt a little stronger, or little more durable. And so, an AV graft is another option for dialysis access.
Catheter
If you're in a situation where you need temporary dialysis, or if you have acute kidney injury, then you may have a temporary Vascath placed, and it's usually placed in a vein of the neck, the internal jugular vein, or it can be placed in the groin, or in the femoral vein.
Who Needs Hemodialysis Treatment?
How do you know if you need hemodialysis, and when is it time to prepare? Well, if you follow up with your kidney doctor (nephrologist) regularly, he or she will be watching your labs. They'll be able to see those signs of your kidneys not functioning properly.
Thought a snake in your boot was bad? That old 19th-century idiom is nothing compared to one in your ear.
Shocking footage captured the alleged moment that a “surgeon” tried to remove a live snake that infiltrated a woman’s ear. Video of the herpetological surgery has racked up more than 125,000 views as viewers speculate whether or not the squirm-inducing footage is authentic.
“The snake has gone in the ear,” reads the caption to the bizarre Facebook clip, which was posted Sept. 1 by an India-based social media star named Chandan Singh to his 20,126 followers. However, it’s unclear where, when or how this unfortunate event transpired, local outlet the Economic Times reported.
In the nearly four-minute clip, an alleged medical practitioner can be seen using tweezers in a desperate attempt to extract a black and yellow serpent that’s peeking its head out from a female patient’s ear.
Bunions can be very painful. ... Bunion removal is a surgical procedure that corrects a deformed area of the foot near the big toe. Bunion removal is sometimes called a bunionectomy, bunion surgery, or hallux valgus correction. Hallux valgus is a Latin phrase that means “foot deformity
Shoulder Clinical Examination - Medical School Clinical Skills - Dr Gill
Personally, I find the shoulder examination the most complex examination possibly as there are so many variations and special tests. Some of which overlap and some will relate specifically to a patients presentation.
Often in a medical school syllabus, only select special tests will be used. In this shoulder exam demonstration, we include the Hawkins-Kennedy Test looking for impingement. This is dovetailed with examination for bicipital tendonitis as this is another possible cause of impingement type symptoms.
This shoulder upper limb exam follows the standard "Look, Feel, Move" orthopaedic exam approach, and overall order as set out in MacLeods Clinical Examination
Watch further orthopaedic examinations for your OSCE revision:

Knee Examination

Hip Joint Clinical Examination

________
Please note that there is no ABSOLUTE way to perform a clinical examination. Different institutions and even clinicians will have differing degrees of variations - the aim is the effectively identify medically relevant signs.
However during OSCE assessments. Different medical schools, nursing colleges, and other health professional courses will have their own preferred approach to a clinical assessment - you should concentrate on THEIR marks schemes for your assessments.
The examination demonstrated here is derived from Macleods Clinical Examination - a recognized standard textbook for clinical skills.

Occiput or cephalic — the baby's head is down, and the baby is facing the mother's abdomen. This position results in back pain and a prolonged labor. Transverse — the baby is lying crosswise in the uterus, side-to-side over the mother's pelvis, in a horizontal position rather than vertical.

Synthol, otherwise known as site enhancement oil is used by some people (including bodybuilders) to increase the apparent size of their muscles by directly injecting the oil into their muscle tissue. Users treat it as a short cut of looking like a body builder, without the actual hard work of bodybuilding training. With repeated injections, a larger volume of synthol builds up inside the muscle, expanding its size like a balloon filling up with air. Side effects of synthol can cause nerve damage, stroke, ulcers, pulmonary embolisms, and much more. Injecting synthol is very dangerous and if that doesn’t deter potential users, there is also a problem from an aesthetic standpoint; synthol use makes ones body look deformed (just see for yourself in the pictures below).
