Diagnosis of a sebaceous cyst

Treatment of sebaceous cyst:

Conductive and mixed conductive/sensory hearing loss

A bone conduction implant (BCI) is used to treat 2 basic problems: conductive and/or mixed hearing loss and deafness in one ear (single-sided deafness). These devices are considered when use of a conventional (air-conduction hearing aid) is not possible. For the case of conductive or mixed hearing loss, they are used most commonly in patients with chronic ear infections, cholesteatoma, and chronic otorrhea in which the diseased eardrum and/or middle ear ossicles are not able to conduct sound to the cochlea and use of a conventional hearing device often is not possible. The other common situation is congenital aural atresia in which absence of the ear canal and eardrum causes conductive hearing loss and a conventional hearing aid cannot be used.

Before Baha, the only device available to treat these situations was a conventional bone conduction hearing aid. This device consists of a bone conduction hearing aid (vibrator) attached to a headband (see the image below). These devices, while very helpful over the years, have several inherent disadvantages that limit their benefit and their acceptance, including the following:

• Discomfort caused by the constant pressure of the vibrator against the scalp
• Poor sound quality and volume caused by the indirect and variable coupling of the vibrator to the skull due to intervening hair and scalp tissues
• Variable and unstable positioning affecting the quality of transduction
• Bilateral use is not possible
• Poor aesthetics

Polycystic Ovary Syndrome :

What is Polycystic Ovary Syndrome?

Polycystic ovary syndrome, or PCOS, is a complex hormone disorder that causes such symptoms as irregular menstrual cycles, infertility, excessive body hair, acne, and obesity.  The syndrome is named for the cysts that may form in the ovaries when the hormone imbalance interrupts the ovulation process.  The term polycystic means “composed of many cysts”.  If the hormone imbalance is left untreated, the syndrome may lead to life-threatening illnesses such as diabetes, heart disease, stroke, and uterine and endometrial cancers.

Symptoms of Polycystic Ovary Syndrome

Because it is a syndrome, PCOS includes a set of symptoms.  Women with PCOS can suffer from any combination of the symptoms listed here.  Some women experience only one of these symptoms, while other women experience all of them.  The severity of PCOS symptoms can vary widely from woman to woman.  Talk to your physician if you suffer from one or more of these symptoms.•

• Chronically irregular menstrual cycles or absent periods
• Infertility or difficulty conceiving (due to not ovulating)
• Obesity (greater than 20 percent over “ideal” weight)
• Sudden, unexplained weight gain (even if you are still of “normal” weight)
• Adult acne
• Excessive hair growth (especially dark hair on the face, chest, or abdomen)
• Male-pattern hair loss or thinning hair
• Type II diabetes or insulin resistance

It is possible to have the above symptoms and not have PCOS.  However, most women with these symptoms, especially irregular menstrual cycles, do have PCOS.  In fact, 80 percent of women with six or fewer periods per year have PCOS.

Researchers have found some variations in the symptoms among different races.  For example, while excessive body hair is found among 70 percent of American women with PCOS, it only occurs in about 10 to 20 percent of Asian women.  Unfortunately, there is not enough evidence to explain why these variations in symptoms occur.

Because the symptoms of PCOS can vary widely, it can be difficult to exclude or include symptoms as a part of the diagnosis.  In face, the World Health Organization tried to determine a comprehensive list of symptoms and couldn’t agree on more than four of them.  Further research is being done at a dozen facilities in the United States alone.  There may be more common symptoms discovered as new studies are completed and women continue reporting their experiences.

Who Is Affected by Polycystic Ovary Syndrome, PCOS?

The most common endocrine disorder, PCOS is estimated to affect anywhere from 5 to 10 percent of all women. That means at least 5 million and as many as 10 million women in the United States suffer from PCOS. The syndrome does not discriminate and can be found in women of all races and ethnic groups throughout the world, although it tends to be more common in women of Mediterranean descent.  PCOS affects women of all ages, from adolescence to menopause.  Once a woman is diagnosed, she will need to manage the symptoms for the rest of her life.

What is Uncemented / Cementless Total Hip Replacement

Total hip replacement is a surgical procedure for replacing the hip joint. This joint is composed of two parts – the hip socket (acetabulum, a cup-shaped bone in the pelvis) and the “ball” or head of the thighbone (femur). During the surgical procedure, these two parts of the hip joint are removed and replaced with smooth artificial surfaces. The artificial socket is made of high-density plastic, while the artificial ball with its stem is made of a strong stainless metal. These artificial pieces are implanted into healthy portions of the pelvis and thighbones and affixed with a bone cement (methyl methacrylate).

An alternative hip prosthesis called a “cementless” total hip replacement has the potential to allow bone to grow into it, and therefore may last longer than the cemented hip. This is an important consideration for the younger patient. In some cases, only one of the two components (socket or stem) may be fixed with cement and the other is cementless and would be called a “hybrid” hip prosthesis.

When is total hip replacement considered ?

Total hip replacements are usually performed for severe arthritic conditions. The operation is sometimes performed for other problems such as hip fractures or avascular necrosis (a condition in which the bone of the hip ball dies). Most patients who have artificial hips are over 55 years of age, but the operation is occasionally performed on younger persons.

Circumstances vary, but generally, patients are considered for total hip replacements if : –

Your pain is severe enough to restrict work, recreation, and the ordinary activities of daily living.
Your pain is not relieved by anti-inflammatory medicine, the use of a cane or walker and restricting activities.
You have significant stiffness of the hip.
Your x-rays show advanced arthritis, or other problems.

The orthopaedic surgeon must be very precise in preparing the femur for a cementless impact. The implant channel must match the shape of the implant itself very closely. New bone growth cannot bridge gaps larger than 1 mm to 2 mm. Your surgeon may recommend a period of protected weight-bearing (using crutches or a walker) to give the bone time to attach itself to the implant. This protected weight bearing helps to ensure there is no movement between the implant and bone so a durable connection can be established.

Cementless femoral components tend to be much larger at the top, with more of a wedge shape. This design enables the strong surface (cortex) of the bone and the dense, hard spongy (cancellous) bone just below it to provide support.

The acetabular component of a cementless total hip replacement also has a coated or textured surface to encourage bone growth into the surface. Depending on the design, these components may also use screws through the cup or spikes, pegs, or fins around the rim to help hold the implant in place until the new bone forms. Usually these components have a metal outer shell and a polyethylene liner.

The pelvis is prepared for a cementless acetabular component using a process similar to that used in a cemented total hip replacement procedure. The intimate contact between the component and bone is crucial to permit bone ingrowth.

Initially, it was hoped that cementless total hip replacement would eliminate the problem of bone resorption or stem loosening caused by cement failure. Although certain cementless stem designs have excellent long-term outcomes, cementless stems can loosen if a strong bond between bone and stem is not achieved.

Patients with large cementless stems may also experience a higher incidence of mild thigh pain. Likewise, polyethylene wear, particulate debris, and the resulting osteolysis (dissolution of bone) remain problems in both cemented and uncemented designs. Improvements in the wear characteristics of newer polyethylene and the advent of hard bearings (metal-on-metal or ceramic) may help resolve some of these problems in the future.

Although some orthopaedic surgeons are now using cementless devices for all patients, cementless total hip replacement is most often recommended for younger, more active patients and patients with good bone quality where bone ingrowth into the components can be predictably achieved. Individuals with juvenile inflammatory arthritis may also be candidates, even though the disease may restrict their activities.

What Is Esophageal Cancer?

Signs and symptoms of pancreatic cancer:

The cervix is a tubelike channel that connects the uterus to the vagina. Cervical polyps are growths that usually appear on the cervix where it opens into the vagina. Polyps are usually cherry-red to reddish-purple or grayish-white. They vary in size and often look like bulbs on thin stems. Cervical polyps are usually not cancerous (benign) and can occur alone or in groups. Most polyps are small, about 1 centimeter to 2 centimeters long. Because rare types of cancerous conditions can look like polyps, all polyps should be removed and examined for signs of cancer.

The cause of cervical polyps is not well understood, but they are associated with inflammation of the cervix. They also may result from an abnormal response to the female hormone estrogen.

Cervical polyps are relatively common, especially in women older than 20 who have had at least one child. They are rare in girls who have not started menstruating. There are two types of cervical polyps:

• Ectocervical polyps can develop from the outer surface layer cells of the cervix. They are more common in postmenopausal women.
• Endocervical polyps develop from cervical glands inside the cervical canal. Most cervical polyps are endocervical polyps, and are more common in premenopausal women.

Symptoms

Cervical polyps may not cause any symptoms. However, you may experience:

• Discharge, which can be foul-smelling if there is an infection
• Bleeding between periods
• Heavier bleeding during periods
• Bleeding after intercourse

Diagnosis

If you have a cervical polyp, you probably won’t be able to feel it or see it. Cervical polyps are discovered during routine pelvic exams or evaluations for bleeding or while getting a Pap test.

Expected Duration

Sometimes a polyp will come off on its own during sexual intercourse or menstruation. However, most polyps need to be removed to treat any symptoms and to evaluate the tissue for signs of cancer, which is rare.

Prevention

Visit your doctor for an annual Pap test and for regular pelvic exams. A direct examination is the best way to identify cervical polyps.

Treatment

Cervical polyps are removed surgically, usually in a doctor’s office. The doctor will use a special instrument, called a polyp forceps, to grasp the base of the polyp stem and then gently pluck the polyp with a gentle, twisting motion. Bleeding is usually brief and limited. Nonprescription, mild pain medication such as acetaminophen (Tylenol and others) or ibuprofen (Advil, Motrin and others) can help to relieve discomfort or cramping during or after the procedure.

The polyp or polyps are sent to a laboratory for examination. You may receive antibiotics if the polyp shows signs of infection. If the polyp is cancerous, treatment will depend on the extent and type of cancer.

Large polyps and polyp stems that are very broad usually need to be removed in an operating room using local, regional or general anesthesia. You will not need to stay in the hospital overnight. Cervical polyps may grow in the future from different areas of the cervix, usually not from the original site. Regular pelvic examination will help to identify and treat polyps before they cause symptoms.

When To Call a Professional

If you experience vaginal discharge, bleeding after intercourse, or bleeding between periods, make an appointment to see your doctor as soon as possible for a pelvic exam.

Prognosis

The outlook is excellent. The vast majority of cervical polyps are not cancerous. Once removed, polyps usually don’t come back.

Humans are the most advanced in the order of creation, they have been gifted with the intellect which they have been using in different fields and helping mankind make his life easier and simpler. With the advance in technology medicine was not far behind. The so called “incurable diseases” started finding a cure, psychiatric patients were unshackled after the discovery of neurotransmitters responsible for psychiatric illnesses. Antibiotics and vaccines started curing and preventing serious infectious diseases.

However the neuro-degenerative diseases such as dementia, MNDs, spinal cord injury, parkinsonism, cerebral palsy etc., still are in search of that elusive drug. But with the discovery of stem cell therapy the hitherto “elusive drug” the magic remedy has been found which has come to salvage scores of patients suffering from these debilitating illnesses.

What is stem cell?
Stem cells can be called as the ‘mother cells’. They originate from the developing embryo and differentiate into different types of cells for example the heart muscle, the liver, brain, skin, bone etc. Etc., They are known as progenitors cells since they lead to creation of new cells.

When these stem cells are transplanted into the body they migrate to the injured areas in the body , get attached there and transform themselves into the tissue desired and replace the damaged one.
This is the theory behind the use of stem cells in most of the neuro-degenerative and autoimmune disorders.

Procedures:

Essentially there are two types of stem cell therapy:

• Autologous therapy where the patient is given stem cells derived from his own bone marrow, or adipose (fat) tissue.
• Allogenic therapy where the donor cells are used ( not the patient himself but some other persons cells are transplanted)

Keloids are raised overgrowths of scar tissue that occur at the site of a skin injury. They occur where trauma, surgery, blisters, vaccinations, acne or body piercing have injured the skin. Less commonly, keloids may form in places where the skin has not had a visible injury. Keloids differ from normal mature scars in composition and size. Some people are prone to keloid formation and may develop them in several places.

Keloids are more common in African-Americans. They are seen most commonly on the shoulders, upper back and chest, but they can occur anywhere. When a keloid is associated with a skin incision or injury, the keloid scar tissue continues to grow for a time after the original wound has closed, becoming larger and more visible until it reaches a final size. They generally occur between 10 and 30 years of age and affect both sexes equally, although they may be more common among young women with pierced ears. Keloids may form over the breastbone in people who have had open heart surgery.

Symptoms:

Keloids usually appear in areas of previous trauma but may extend beyond the injured area. They are shiny, smooth and rounded skin elevations that may be pink, purple, or brown. They can be doughy or firm and rubbery to the touch, and they often feel itchy, tender or uncomfortable. They may be unsightly. A large keloid in the skin over a joint may interfere with joint function.

Expected Duration:

Keloids may continue to grow slowly for weeks, months or years. They eventually stop growing but do not disappear on their own. Once a keloid develops, it is permanent unless removed or treated successfully. It is common for keloids that have been removed or treated to return.

Prevention

People who are prone to keloids should avoid cosmetic surgery. When surgery is necessary in such people, doctors can take special precautions to minimize the formation of keloids at the site of the incision. Examples of techniques that might be used to minimize keloid formation include covering the healing wound with hypoallergenic paper tape for several weeks after surgery, covering the wound with small sheets made of a silicone gel after the surgery, or using corticosteroid injections or radiation treatments at the site of the surgical wound at the beginning of the healing period.

Treatment

There is no single treatment for keloids, and most treatments do not give completely satisfying results. Two or more treatments may be combined. If you decide to pursue treatment for a keloid scar, you will have the best results if you start treatment soon after the keloid appears. Available treatments include:

• Removal with conventional surgery — This unreliable technique requires great care, and keloids that return after being removed may be larger than the original. Keloids return in more than 45% of people when they are removed surgically. Keloids are less likely to return if surgical removal is combined with other treatments.
• Dressings — Moist wound coverings made of silicone gel sheets have been shown in studies to sometimes reduce the size of keloids over time. This treatment is safe and painless.
• Corticosteroid injections — Injections with triamcinolone acetonide or another corticosteroid medicine typically are repeated at intervals of four to six weeks. This treatment can often reduce keloid size and irritation, but injections are uncomfortable.
• Compression — This involves using a bandage or tape to apply continuous pressure 24 hours a day for a period of six to 12 months. Such compression can cause a keloid to become smaller. For keloids that form at the site of an ear piercing, a clip known as a “Zimmer splint” usually reduces keloid size by at least 50% after one year of compression. Zimmer splints that resemble earrings are available.
• Cryosurgery — This freezing treatment with liquid nitrogen is repeated every 20 to 30 days. It can cause a side effect of lightening the skin color, which limits this treatment’s usefulness.
• Radiation therapy — This therapy is controversial because radiation increases the risk of cancer. Radiation treatments may reduce scar formation if they are used soon after a surgery, during the time a surgical wound is healing.
• Laser therapy — This is an alternative to conventional surgery for keloid removal. There is no good evidence that keloids are less likely to return after laser therapy than after regular surgery.
• Experimental treatments — One treatment showing promise is injecting keloid scars with medicines that were developed to treat autoimmune illnesses or cancers. Treatments with these medicines (various types of interferon and the chemotherapy agents 5-fluorouracil and bleomycin) will need to be evaluated further before they are appropriate for use outside of research studies.
