Spirotome macrobiopsy of a lung as a minimal invasive way to complete the diagnosis of lung lesions.

Lumpectomy means that a focal area of cancer is going to be removed. A lot of patients with a lumpectomy don’t need any specific breast reconstruction, explains Dr. Miguel Angel Medina, Director of Microsurgery with Miami Cancer Institute.
Al the end of surgical treatment, all those patients go on to need radiation therapy. For patients who have large breasts, physicians have to take a larger lumpectomy than normal.

PEOPLE WITH A SEXUALLY ACTIVE LIFE SHOULD BE AWARE OF THIS SILENT KILLER

Varicose veins are generally benign. The cause of this condition is not known. For many people, there are no symptoms and varicose veins are simply a cosmetic concern. In some cases, they cause aching pain and discomfort or signal an underlying circulatory problem. Treatment involves compression stockings, exercise, or procedures to close or remove the veins.

atrial septal defect (ASD) is a hole in the wall between the two upper chambers of your heart (atria). The condition is present from birth (congenital). Small atrial septal defects may close on their own during infancy or early childhood. Large and long-standing atrial septal defects can damage your heart and lungs. Small defects may never cause a problem and may be found incidentally. An adult who has had an undetected atrial septal defect for decades may have a shortened life span from heart failure or high blood pressure that affects the arteries in the lungs (pulmonary hypertension). Surgery may be necessary to repair atrial septal defects to prevent complications

A thyroid biopsy is a procedure in which a small sample of tissue is removed from the thyroid gland and looked at under a microscope for cancer, infection, or other thyroid problems. The thyroid gland is found in front of the windpipe (trachea), just below the voice box (larynx). A sample of thyroid tissue can be taken by: Fine-needle biopsy. Your doctor puts a thin needle through the skin and into the thyroid gland. Many thyroid specialists like to use a needle biopsy method rather than surgery. Open biopsy. Your doctor makes a cut (incision) through the skin to see the thyroid gland. This method is done when other tests have not found the cause of your symptoms. Core needle biopsy. Your doctor inserts a needle with a special tip and removes a sample of tissue about the size of a grain of rice.

Dehydration can also be a cause of kidney stones. A common symptom is having a lower left abdominal pain, fever, nausea, groin pain and vomiting. Lower left abdominal pain can also be caused by an infection of the kidneys. It usually begins with the bladder and then reaches out to the kidneys.

Possible causes are a blocked milk duct or bacteria entering the breast. It usually occurs within the first three months of breast-feeding. Symptoms include breast pain, swelling, warmth, fever, and chills. Antibiotics are required. Mild pain relievers can help with discomfort.

This test stimulates your acoustic nerve by delivering cold or warm water or air into your ear canal. When cold water or air enters your ear and the inner ear changes temperature, it should cause fast, side-to-side eye movements called nystagmus. The test is done in the following way: Before the test, your ear, especially the eardrum, will be checked. This is to make sure it is normal. One ear is tested at a time. A small amount of cold water or air is gently delivered into one of your ears. Your eyes should show an involuntary movement called nystagmus. Then they should turn away from that ear and slowly back. If water is used, it is allowed to drain out of the ear canal. Next, a small amount of warm water or air is gently delivered into the same ear. Again, your eyes should show nystagmus. Then they should turn toward that ear and slowly back. Your other ear is tested in the same way.

What could cause a blockage in the stomach? Mechanical causes of intestinal obstruction may include: Adhesions or scar tissue that forms after surgery. Foreign bodies (objects that are swallowed and block the intestines) Gallstones (rare) Hernias. Impacted stool. Intussusception (telescoping of one segment of bowel into another) Tumors blocking the intestines. Less common radiologic signs are seen in specific circumstances. Most closed-loop obstructions (75%) are caused by adhesions. A closed-loop obstruction occurs when a loop of bowel is not decompressed by the caudal passage of gas and fluid.

Histology of Tooth Eruption

Benign prostatic hyperplasia (BPH), also known as benign prostatic hypertrophy, is a histologic diagnosis characterized by proliferation of the cellular elements of the prostate. Cellular accumulation and gland enlargement may result from epithelial and stromal proliferation, impaired preprogrammed cell death (apoptosis), or both. BPH involves the stromal and epithelial elements of the prostate arising in the periurethral and transition zones of the gland (see Pathophysiology). The hyperplasia presumably results in enlargement of the prostate that may restrict the flow of urine from the bladder. BPH is considered a normal part of the aging process in men and is hormonally dependent on testosterone and dihydrotestosterone (DHT) production. An estimated 50% of men demonstrate histopathologic BPH by age 60 years. This number increases to 90% by age 85 years. The voiding dysfunction that results from prostate gland enlargement and bladder outlet obstruction (BOO) is termed lower urinary tract symptoms (LUTS). It has also been commonly referred to as prostatism, although this term has decreased in popularity. These entities overlap; not all men with BPH have LUTS, and likewise, not all men with LUTS have BPH. Approximately half of men diagnosed with histopathologic BPH demonstrate moderate-to-severe LUTS. Clinical manifestations of LUTS include urinary frequency, urgency, nocturia (awakening at night to urinate), decreased or intermittent force of stream, or a sensation of incomplete emptying. Complications occur less commonly but may include acute urinary retention (AUR), impaired bladder emptying, the need for corrective surgery, renal failure, recurrent urinary tract infections, bladder stones, or gross hematuria. (See Presentation.) Prostate volume may increase over time in men with BPH. In addition, peak urinary flow, voided volume, and symptoms may worsen over time in men with untreated BPH (see Workup). The risk of AUR and the need for corrective surgery increases with age.

Wondering how pregnancy happens? It’s not as simple as it seems! Pregnancy takes several days, and there are lots of steps. Here are the basics on how pregnancy works.

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).

Acute aortic dissection can be treated surgically or medically. In surgical treatment, the area of the aorta with the intimal tear is usually resected and replaced with a Dacron graft. Emergency surgical correction is the preferred treatment for Stanford type A (DeBakey type I and II) ascending aortic dissection. It is also preferred for complicated Stanford type B (DeBakey type III) aortic dissections with clinical or radiologic evidence of the following conditions: Propagation (increasing aortic diameter) Increasing size of hematoma Compromise of major branches of the aorta Impending rupture Persistent pain despite adequate pain management Bleeding into the pleural cavity Development of saccular aneurysm
