Nasal polyps are associated with inflammation of the lining of your nasal passages and sinuses that lasts more than 12 weeks (chronic rhinosinusitis, also known as chronic sinusitis). However, it's possible — and even somewhat more likely — to have chronic sinusitis without nasal polyps. Nasal polyps themselves are soft and lack sensation, so if they're small you may not be aware you have them. Multiple growths or a large polyp may block your nasal passages and sinuses.
Following Dr. Eric Skarsgard on his grueling 19-hour day at BC Children's Hospital, we meet several of his patients -- some of who need surgery that day, and some who have chronic conditions and need regular check-ups with him -- and learn how he works with medical students and on research projects as time allows.
This video shows Prof Dan Reinstein, MD MA(Cantab) FRCSC DABO FRCOphth FEBO performing a ReLEx SMILE keyhole LASIK procedure using the latest surgical instrument that he helped to develop (Malosa MMSU1297 - Reinstein Lenticule Separator: http://www.malosa.com/en/reinstein-le...). This instrument enables the procedure to be performed with one instrument, through one 2mm incision, using only one sweep per plane, and taking about 30 seconds to separate and withdraw the lenticule, improving day 1 uncorrected vision over other lenticule extraction techniques that require more corneal manipulation.
Bell's palsy is a form of facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve-also called the 7th cranial nerve-travels through a narrow, bony canal (called the Fallopian canal) in the skull, beneath the ear, to the muscles on each side of the face. For most of its journey, the nerve is encased in this bony shell. Each facial nerve directs the muscles on one side of the face, including those that control eye blinking and closing, and facial expressions such as smiling and frowning. Additionally, the facial nerve carries nerve impulses to the lacrimal or tear glands, the saliva glands, and the muscles of a small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue. When Bell's palsy occurs, the function of the facial nerve is disrupted, causing an interruption in the messages the brain sends to the facial muscles. This interruption results in facial weakness or paralysis. Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who described the facial nerve and its connection to the condition. The disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell's palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides.
Acute kidney injury is common entity in medical practice. The present definition is based on a serum creatinine rise of more 0.3 mg/dl in 48 hours or less, a 50% increase from the baseline over a period of 07 days or a urine output of less than 0.5 ml/kg/hour for more than 06 hours. The main causes of acute kidney injury may be classified into pre renal, intrinsic or post renal causes. Rapid diagnosis and prompt treatment is essential to prevent mortality or morbidity. This presentation discusses in detail the causes of all three mechanisms, pre-renal, post renal and intrinsic.
Peripheral artery disease (P.A.D.) is a disease in which plaque builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in the body's arteries, the condition is called atherosclerosis. Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. P.A.D. usually affects the arteries in the legs, but it also can affect the arteries that carry blood from your heart to your head, arms, kidneys, and stomach. This article focuses on P.A.D. that affects blood flow to the legs.
The cardiac examination is one of the earliest clinical skills that medical students learn. As a junior doctor, the examination of the cardiovascular system can be almost a dreaded examination, as cardiac murmurs can literally take years of exposure in order to gain confidence with their identification through cardiac auscultation.
This video demonstrates not merely the examination of the heart, but the complete cardiovascular system including peripheries.

Septoplasty (SEP-toe-plas-tee) is a surgical procedure to correct a deviated septum — a displacement of the bone and cartilage that divides your two nostrils. During septoplasty, your nasal septum is straightened and repositioned in the middle of your nose.
Dr. Shaun Kunisaki is an Associate Professor of Surgery at The Johns Hopkins University and Associate Chief of Strategy and Integration in the Division of General Pediatric Surgery at the Johns Hopkins Children's Center. His clinical practice spans the full breadth of pediatric general surgery, but he is recognized both regionally and nationally for this expertise in complex thoracic surgical problems in the fetus and young child. As Director of Pediatric Esophageal Surgery, he specializes in the management of long-gap esophageal atresia. In this role within the Johns Hopkins Children Center Fetal Program, he helps counsel parents with pregnancies complicated by fetal anomalies.
