A glucagonoma is a rare tumor of the alpha cells of the pancreas that results in the overproduction of the hormone glucagon. Alpha cell tumors are commonly associated with glucagonoma syndrome, though similar symptoms are present in cases of pseudoglucagonoma syndrome in the absence of a glucagon-secreting tumor.

LASIK, or "laser-assisted in situ keratomileusis," is the most commonly performed laser eye surgery to treat myopia, hyperopia and astigmatism. The goal of the treatment is to reshape the cornea to correct the refractive error of the eye.
The cornea is the transparent dome-shaped structure in front of the eye. The cornea refracts light and accounts for about two-thirds of the eye's total optical power. Altering the curvature of the cornea changes the way light rays enter the eye. As a result, the light rays can be focused properly onto the retina for clearer vision.
For nearsighted people, the laser is used to flatten the cornea. For farsighted people, the cornea is made steeper. For patients with astigmatism, the laser is used to smooth the irregularly-shaped cornea into a more regular shape.
The outer layer of the cornea - the epithelium – is capable of replacing itself within a few days after being damaged or removed. The deeper layer of the cornea – the stroma, on the contrary, is a permanent corneal tissue with very limited regenerative capacity. The stroma, if reshaped by a laser, will remain that way permanently.
In this procedure, a thin, circular "FLAP" is created in the surface of the cornea to gain access to the permanent corneal tissue. This can be done with a mechanical cutting tool called a microkeratome, OR, for a blade-free experience, by a femtosecond laser. An excimer laser is then used to remove some corneal tissue to reshape the cornea. Excimer laser uses cool ultraviolet light beams to vaporize microscopic amounts of tissue in a precise manner to accurately reshape the cornea. The excimer laser is computer-controlled and is programmed based on the patient’s refractive error. The flap is then laid back in place and is allowed to heal.
LASIK eye surgery is mostly painless and can be completed within minutes. Improved vision can usually be seen overnight.

PRK, or photorefractive keratectomy, was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. In PRK, NO flap is created. Rather, the epithelial cells on the eye surface are simply removed. An excimer laser is then used to reshape the cornea just like it does in LASIK.
The vision correction outcomes of PRK surgery are comparable to those of LASIK, but the recovery period is longer. This is because the epithelium is completely removed in PRK and it takes a few days to regenerate. PRK patients also have more discomfort and haziness of vision in the first few days after the surgery. Improved vision also takes longer to achieve.
PRK does, however, offer certain advantages. Because PRK does not involve creation of a flap, which contains both epithelial and deeper stromal tissue, the entire thickness of the stroma is available for treatment. The treatment range is therefore higher. This is particularly useful for patients with high levels of myopia or for those whose cornea is too thin for LASIK. PRK is also free of flap-related complication risks.

Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures (BPs) lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment

Psoriatic arthritis is a chronic arthritis. In some people, it is mild, with just occasional flare ups. In other people, it is continuous and can cause joint damage if it is not treated. Early diagnosis is important to avoid damage to joints. Psoriatic arthritis typically occurs in people with skin psoriasis, but it can occur in people without skin psoriasis, particularly in those who have relatives with psoriasis. Psoriatic arthritis typically affects the large joints, especially those of the lower extremities, distal joints of the fingers and toes, and also can affect the back and sacroiliac joints of the pelvis. For most people, appropriate treatments will relieve pain, protect the joints, and maintain mobility. Physical activity helps maintain joint movement. Psoriatic arthritis is sometimes misdiagnosed as gout, rheumatoid arthritis or osteoarthritis. - See more at: http://www.rheumatology.org/I-Am-A/Patient-Caregiver/Diseases-Conditions/Psoriatic-Arthritis#sthash.VsBTUw76.dpuf

One of the most common knee injuries in contact and collision sports is a medial collateral ligament (MCL) injury. This is a ligament on the medial (side closest to the midline) side of your knee that provides stability against side-to-side stress to the knee. You might injure it by cutting maneuvers in sports like soccer or hockey. You can also suffer an MCL injury if another player hits you on the outside of your knee.

Also, in the past I used "keratinocyte" and "squamous cell" interchangeably (this is because in dermatopathology, we see and talk about squamous cell carcinomas all the time, and those tumors are composed of keratinocytes). But technically, in normal skin histology, "squamous cell" refers only to the flattened keratinocytes in the superficial epidermis. Thankfully, a histology PhD colleague pointed this out to me and corrected my lazy nomenclature!

An older patient with stomach pain, and the typical heart burning. We did some biopsies for evaluation of dyplasia.

Juvenile rheumatoid arthritis, also known as juvenile idiopathic arthritis, is the most common type of arthritis in children under the age of 17. Juvenile rheumatoid arthritis causes persistent joint pain, swelling and stiffness. Some children may experience symptoms for only a few months, while others have symptoms for the rest of their lives. Some types of juvenile rheumatoid arthritis can cause serious complications, such as growth problems and eye inflammation. Treatment of juvenile rheumatoid arthritis focuses on controlling pain, improving function and preventing joint damage.

An enlarged spleen may cause: No symptoms in some cases. Pain or fullness in the left upper abdomen that may spread to the left shoulder. Feeling full without eating or after eating only a small amount from the enlarged spleen pressing on your stomach. Anemia. Fatigue. Frequent infections. Easy bleeding.

Several options are available to remove spider veins — thin red lines or weblike networks of blood vessels that appear on your legs and feet. Spider veins are usually harmless, though they can sometimes cause aching, burning or pain, especially when you've been standing for long periods. If you have symptoms or are concerned about the appearance of spider veins, treatment options include: Sclerotherapy. In this procedure, your doctor injects the veins with a solution that scars and closes those veins, causing the blood to reroute through healthier veins. In a few weeks, treated spider veins fade. Although the same vein may need to be injected more than once, sclerotherapy is usually effective if done correctly. Sclerotherapy doesn't require anesthesia and can be done in your doctor's office. Side effects include swelling, itching and skin color changes in the treated area. Laser surgery. Laser surgery works by sending strong bursts of light into the vein that make the vein slowly fade and disappear. No incisions or needles are used. The treatment is often less effective than sclerotherapy, particularly for larger veins. Side effects may include redness, bruising, itching, swelling and permanent skin tone changes. After treatment, blood vessels fade over several months, but they may not disappear completely. Also, new spider veins can develop in the same area.
