Thyroid nodules increase with age and are present in almost 10% of the adult population. Autopsy studies reveal the presence of thyroid nodules in 50% of the population, so they are fairly common. 95% of solitary thyroid nodules are benign, and therefore, only 5% of thyroid nodules are malignant.
LASIK eye surgery is commonly performed laser refractive surgery to correct vision problems. This 3d animation shows how laser-assisted in situ keratomileusis (lasik) can be an alternative to glasses or contact lenses.
It’s one of many vision correction surgeries that work by reshaping your cornea, the clear front part of your eye, so that light focuses on the retina in the back of your eye.
In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision.
During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eyes (cornea) to improve vision.
Glasses or contact lenses can correct vision, but reshaping the cornea itself also will provide the necessary refraction.

To record the sequence, Stephan Gordts and Ivo Brosens of the Leuven Institute for Fertility & Embryology in Belgium performed transvaginal laparoscopy, which involves making a small cut in the vaginal wall and observing the ovary with an endoscope.
"This allows us direct access to and observation of the tubo-ovarian structures without manipulation using forceps," says Gordts.
For the photos of ovulation, which only accidentally captured the critical moment, Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium, used gas to distend the organs for photography. However, Gordts and Brosens planned the procedure to coincide with ovulation and used saline solution to "float" the structures.
Perfect timing
Observation was timed for the day of the peak of the patient's luteal hormone cycle. Ovulation was predicted to occur on the evening of the day of the LH peak, and the endoscope introduced at 6 pm.
A small amount of saline was used to float the opening of the fallopian tube, its fimbriae (the "fingers" that sweep the egg into the tube) and the ovary itself. This gives a more natural appearance than gas, says Gordts.
In the video, the fimbriae can be seen sweeping in time with the patient's heartbeat. A mucus plug can be seen protruding from the ovary – this contains the egg.
"The ovum is not captured 'naked'," says Gordts. "There is no eruption like a volcano."
Gordts says that in clinical practice it is not easy to organise the observation of ovulation. "We were probably lucky to be successful at our first attempt," he says.

An amputation is the removal of an extremity or appendage from the body. Amputations in the upper extremity can occur as a result of trauma, or they can be performed in the treatment of congenital or acquired conditions. Although successful replantation represents a technical triumph to the surgeon, the patient's best interests should direct the treatment of amputations. The goals involved in the treatment of amputations of the upper extremity include the following : Preservation of functional length Durable coverage Preservation of useful sensibility Prevention of symptomatic neuromas Prevention of adjacent joint contractures Early return to work Early prosthetic fitting These goals apply differently to different levels of amputation. Treatment of amputations can be challenging and rewarding. It is imperative that the surgeon treat the patient with the ultimate goal of optimizing function and rehabilitation and not become absorbed in the enthusiasm of the technical challenge of the replantation, which could result in poorer outcome and greater financial cost due to lost wages, hospitalization, and therapy.
Electrical injuries can present with a variety of problems, including cardiac or respiratory arrest, coma, blunt trauma, and severe burns of several types. It is important to establish the type of exposure (high or low voltage), duration of contact, and concurrent trauma. Low-voltage AC injury without loss of consciousness and/or arrest These injuries are exposures of less than 1000V and usually occur in the home or office setting. Typically, children with electrical injuries present after biting or chewing on an electrical cord and suffer oral burns. Adults working on home appliances or electrical circuits can also experience these electrical injuries. Low-voltage AC may result in significant injury if there is prolonged, tetanic muscle contraction. Low-voltage AC injury with loss of consciousness and/or arrest In respiratory arrest or ventricular fibrillation that is not witnessed, an electrical exposure may be difficult to diagnose. All unwitnessed arrests should include this possibility in the differential diagnosis. Query EMS personnel, family, and coworkers about this possibility. Inquire if a scream was heard before the patient’s collapse; this may be due to involuntary contraction of chest wall muscles from electrical current. High-voltage AC injury without loss of consciousness and/or arrest Usually high-voltage injuries do not cause loss of consciousness but instead cause devastating thermal burns. In occupational exposures, details of voltage can be obtained from the local power company. High-voltage AC injury with loss of consciousness and/or arrest This is an unusual presentation of high-voltage AC injuries, which do not often cause loss of consciousness. History may need to come from bystanders or EMS personnel. Direct current (DC) injury These injuries typically cause a single muscle contraction that throws the victim away from the source. They are rarely associated with loss of consciousness unless there is severe head trauma, and victims can often provide their own history. Conducted electrical devices Conducted electrical weapons (CEWs) such as tasers are weapons used by law enforcement that deliver high-voltage current that is neither true AC or DC but is most like a series of low-amplitude DC shocks.[16] They can deliver 50,000 V in a 5-second pulse, with an average current of 2.1 mA.[17] Though they have been temporally associated with deaths in the law enforcement setting, conducted electrical devices (CEDs) in healthy volunteers have been shown to be safe without evidence of delayed arrhythmia or cardiac damage as measured by troponin I.[18, 17] One study of their use in 1201 law enforcement incidents showed mostly superficial puncture wounds from the device probes, and significant injuries only from trauma subsequent to shock, not from the device itself. Of 2 deaths in custody, neither was related to CEW exposure.[19]
How to start a peripheral IV in the dorsum of the hand: clinical nursing skill technique.
Starting an IV (intravenous catheter) can be an intimidating experience for nurses, especially nursing students and new nurses. However, nurses will perform IV insertions often, so this is an important nursing skill to learn.
Before starting an IV, always follow the protocols of your facility, as well as manufacturer's instructions for any supplies used.
In this video, Nurse Sarah demonstrates how to start a peripheral IV in the dorsum of the hand. Prior to inserting the IV, you'll want to do the following:
-Gather supplies
-Perform hand hygiene
-Prepare supplies (including priming the saline flush, removing air from extension tubing, opening packages, completing labels, and any other steps required by your facility.
-Locate a suitable vein
-Perform hand hygiene
-Don gloves
If the patient has a lot of hair, you might want to use clippers to trim the hairs prior to starting the IV. You may also apply a tourniquet to help veins move near the surface of the skin.
Next, you'll want to clean the site using the cleaner that came in the IV start kit, such as ChloraPrep.
Once the site has dried completely, you can insert the IV. Stabilize the vein with your non-dominant hand, and insert the IV's needle into the vein, watching carefully for blood return (or a blood flash) in the chamber. Advance the IV around 2mm more to ensure the plastic cannula is in the vein, then thread the cannula into the vein and press the needle safety button.

his patient had spilled boiling water on his lower leg a couple days before. This isn't complicated but the teaching points should focus on draining the large blistered areas and attempting to maintain moisture as long as we can so the skin doesn't contract down on itself.
Hypertrophic cardiomyopathy (HCM) is very common and can affect people of any age. It affects men and women equally. It is a common cause of sudden cardiac arrest in young people, including young athletes. Hypertrophic cardiomyopathy occurs if heart muscle cells enlarge and cause the walls of the ventricles (usually the left ventricle) to thicken. The ventricle size often remains normal, but the thickening may block blood flow out of the ventricle. If this happens, the condition is called obstructive hypertrophic cardiomyopathy. Sometimes the septum, the wall that divides the left and right sides of the heart, thickens and bulges into the left ventricle. This can block blood flow out of the left ventricle. Then the ventricle must work hard to pump blood. Symptoms can include chest pain, dizziness, shortness of breath, or fainting. Hypertrophic cardiomyopathy also can affect the heart's mitral valve, causing blood to leak backward through the valve. Sometimes, the thickened heart muscle doesn't block blood flow out of the left ventricle. This is referred to as non-obstructive hypertrophic cardiomyopathy. The entire ventricle may thicken, or the thickening may happen only at the bottom of the heart. The right ventricle also may be affected. In both obstructive and non-obstructive HCM, the thickened muscle makes the inside of the left ventricle smaller, so it holds less blood. The walls of the ventricle may stiffen, and as a result, the ventricle is less able to relax and fill with blood.
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.
