Smell and taste problems can have a big impact on our lives. Because these senses contribute substantially to our enjoyment of life, and our desire to eat and be social, smell and taste disorders can be serious. When they are impaired, life loses some zest, we eat poorly, socialize less and, as a result, feel worse. Many older people experience this problem.
Smell and taste also warn us about dangers, such as fire, poisonous fumes, and spoiled food. Certain jobs require that these senses be accurate -- chefs and firemen rely on taste and smell.One study estimates that more than 200,000 people visit a doctor with smell and taste disorders every year but, many more cases go unreported.
Loss of the sense of smell may be a sign of sinus disease, growths in the nasal passages or, in rare circumstances, brain tumors.
Fever blisters are fluid-filled blisters that commonly occur on the lips. They also can occur on the gums and roof of the mouth (hard palate), but this is rare. Fever blisters are usually painful; pain may precede the appearance of the lesion by a few days. The blisters rupture within hours, then crust over. They last about seven to ten days.
Fever blisters result from a herpes simplex virus that becomes active. This virus is latent (dormant) in afflicted people, but can be activated by conditions such as stress, fever, trauma, hormonal changes, and exposure to sunlight. When lesions reappear, they tend to form in the same location.
Yes, the time from blister rupture until the sore is completely healed is the time of greatest risk for spread of infection. The virus can spread to the afflicted person’s eyes and genitalia, as well as to other people.
Treatment consists of coating the lesions with a protective barrier ointment containing an antiviral agent, for example 5% acyclovir ointment. While there is no cure now, scientists are working on trying to develop one and hopefully fever blisters will be a curable disorder in the future.
Tips to prevent spreading fever blisters:
(Note: Despite all caution, it is possible to transmit herpes virus even when no blisters are present.)
Canker sores (also called aphthous ulcers) are different than fever blisters. They are small, red or white, shallow ulcers occurring on the tongue, soft palate, or inside the lips and cheeks; they do not occur in the roof of the mouth or the gums. They are quite painful, and usually last five–ten days.
Eighty percent of the U.S. population between the ages of ten to 20 years of age, most often women, get canker sores.
The best available evidence suggests that canker sores result from an altered local immune response associated with stress, trauma, or irritation. Acidic foods (i.e., tomatoes, citrus fruits, and some nuts) are known to cause irritation in some patients.
No, because they are not caused by bacteria or viral agents, they cannot be spread locally or to anyone else.
The treatment is directed toward relieving discomfort and guarding against infection. A topical corticosteroid preparation such as triamcinolone dental paste (Kenalog in Orabase 0.1%®) is helpful.
Consider consulting a physician if a mouth sore has not healed within two weeks. Mouth sores offer an easy way for germs and viruses to get into the body. Therefore, it is easy for infections to develop.
People who consume alcohol, smokers, smokeless tobacco users, chemotherapy or radiation patients, bone marrow or stem cell recipients, or patients with weak immune systems should also consider having regular oral screenings by a physician. The first sign of oral cancer is a mouth sore that does not heal.
The physician will most likely examine the head, face, neck, lips, gums, and high-risk areas inside the mouth, such as the floor of the mouth, the front and sides of the tongue, and the roof of the mouth or soft palate. If a suspicious lesion is found, the physician may recommend collecting and testing soft tissue from the oral cavity.
Gastroesophageal reflux, often referred to as GERD, occurs when acid from the stomach backs up into the esophagus. Normally, food travels from the mouth, down through the esophagus and into the stomach. A ring of muscle at the bottom of the esophagus, the lower esophageal sphincter (LES), contracts to keep the acidic contents of the stomach from “refluxing” or coming back up into the esophagus. In those who have GERD, the LES does not close properly, allowing acid to move up the esophagus.
When stomach acid touches the sensitive tissue lining the esophagus and throat, it causes a reaction similar to squirting lemon juice in your eye. This is why GERD is often characterized by the burning sensation known as heartburn.
In some cases, reflux can be SILENT, with no symptoms until a problem arises. Almost all individuals have experienced reflux (GER), but the disease (GERD) occurs when reflux happens on a frequent basis often over a long period of time.
During gastroesophageal reflux, the acidic stomach contents may reflux all the way up the esophagus, beyond the upper esophageal sphincter (a ring of muscle at the top of the esophagus), and into the back of the throat and possibly the back of the nasal airway. This is known as laryngopharyngeal reflux (LPR), which can affect anyone. Adults with LPR often complain that the back of their throat has a bitter taste, a sensation of burning, or something “stuck.” Some may have difficulty breathing if the voice box is affected.
In infants and children, LPR may cause breathing problems such as: cough, hoarseness, stridor (noisy breathing), croup, asthma, sleep disordered breathing, feeding difficulty (spitting up), turning blue (cyanosis), aspiration, pauses in breathing (apnea), apparent life threatening event (ALTE), and even a severe deficiency in growth. Proper treatment of LPR, especially in children, is critical.
The symptoms of GERD may include persistent heartburn, acid regurgitation, nausea, hoarseness in the morning, or trouble swallowing. Some people have GERD without heartburn. Instead, they experience pain in the chest that can be severe enough to mimic the pain of a heart attack. GERD can also cause a dry cough and bad breath. Some people with LPR may feel as if they have food stuck in their throat, a bitter taste in the mouth on waking, or difficulty breathing although uncommon.
If you experience any of the following symptoms on a regular basis (twice a week or more) then you may have GERD or LPR. For proper diagnosis and treatment, you should be evaluated by your primary care doctor for GERD or an otolaryngologist—head and neck surgeon (ENT doctor).
Women, men, infants, and children can all have GERD. This disorder may result from physical causes or lifestyle factors. Physical causes can include a malfunctioning or abnormal lower esophageal sphincter muscle (LES), hiatal hernia, abnormal esophageal contractions, and slow emptying of the stomach. Lifestyle factors include diet (chocolate, citrus, fatty foods, spices), destructive habits (overeating, alcohol and tobacco abuse) and even pregnancy. Young children experience GERD and LPR due to the developmental immaturity of both the upper and lower esophageal sphincters.
Unfortunately, GERD and LPR are often overlooked in infants and children leading to repeated vomiting, coughing in GER and airway and respiratory problems in LPR such as sore throat and ear infections. Most infants grow out of GERD or LPR by the end of their first year; however, the problems that resulted from the GERD or LPR may persist.
A gastroenterologist, a specialist in treating gastrointestinal orders, will often provide initial treatment for GERD. But there are ear, nose, and throat problems that are either caused by or associated with GERD, such as hoarseness, laryngeal (singers) nodules, croup, airway stenosis (narrowing), swallowing difficulties, throat pain, and sinus infections. These problems require an otolaryngologist—head and neck surgeon, or a specialist who has extensive experience with the tools that diagnose GERD and LPR. They treat many of the complications of GERD, including: sinus and ear infections, throat and laryngeal inflammation and lesions, as well as a change in the esophageal lining called Barrett’s esophagus, which is a serious complication that can lead to cancer.
Your primary care physician or pediatrician will often refer a case of LPR to an otolaryngologist—head and neck surgeon for evaluation, diagnosis, and treatment.
In adults, GERD can be diagnosed or evaluated by a physical examination and the patient’s response to a trial of treatment with medication. Other tests that may be needed include an endoscopic examination (a long tube with a camera inserted into the nose, throat, windpipe, or esophagus), biopsy, x-ray, examination of the throat and larynx, 24 hour pH probe, acid reflux testing, esophageal motility testing (manometry), emptying studies of the stomach, and esophageal acid perfusion (Bernstein test). Endoscopic examination, biopsy, and x-ray may be performed as an outpatient or in a hospital setting. Endoscopic examinations can often be performed in your ENT’s office, or may require some form of sedation and occasionally anesthesia.
Symptoms of GERD or LPR in children should be discussed with your pediatrician for a possible referral to a specialist.
Most people with GERD respond favorably to a combination of lifestyle changes and medication. On occasion, surgery is recommended. Medications that could be prescribed include antacids, histamine antagonists, proton pump inhibitors, pro-motility drugs, and foam barrier medications. Some of these products are now available over-the-counter and do not require a prescription.
Children and adults who fail medical treatment or have anatomical abnormalities may require surgical intervention. Such treatment includes fundoplication, a procedure where a part of the stomach is wrapped around the lower esophagus to tighten the LES, and endoscopy, where hand stitches or a laser is used to make the LES tighter.
The skin is the largest organ in our body. It provides protection against heat, cold, light, and infection. The skin is made up of two major layers (epidermis and dermis) as well as various types of cells (see figure). The top (or outer) layer of the skin—the epidermis—is composed of three types of cells: flat, scaly cells on the surface called squamous cells; round cells called basal cells; and melanocytes, cells that provide skin its pigment or color and protect against skin damage. The inner layer of the skin—the dermis—is the layer that contains the nerves, blood vessels, and sweat glands.
Skin cancer is a disease in which cancer (malignant) cells are found in the outer layers of your skin. There are several types of cancer that originate in the skin. The most common types are basal cell carcinoma (70 percent of all skin cancers) and squamous cell carcinoma (20 percent). These types are classified as non-melanoma skin cancer.
Melanoma (5 percent of all skin cancer) is the third major type of skin cancer. It is less common than basal cell or squamous cell skin cancer, but potentially much more serious. Other types of skin cancer are rare.
Skin cancer is a disease that has shown a steady increase over the last 20 years. Fortunately, with early diagnosis and treatment it remains a very curable disease. A variety of factors have been identified which place a person at a higher risk to develop skin cancer (see “Am I at risk?” )
The most important first step is early diagnosis. The vast majority of skin cancers can be cured if diagnosed and treated early. Aside from protecting your skin from sun damage, it is important to recognize the early signs of skin cancer:
If you notice any of the factors listed above see your doctor right away. If you have a spot or lump on your skin, your doctor may remove the growth and examine the tissue under the microscope. This is called a biopsy. A biopsy can usually be done in the doctor's office after numbing the skin with a local anesthetic. Examination of the biopsy under the microscope will tell the doctor if the skin lesion is a cancer (malignancy).
There are varieties of treatments available (including surgery, radiation therapy, and chemotherapy) to treat skin cancer. Treatment for skin cancer depends on the type and size of cancer, your age, and your overall health.
Surgery is the most common form of treatment. This generally consists of an office or outpatient procedure to excise the lesion and check edges to make sure all the cancer was removed. In many cases, the site is then repaired with simple stitches (primary closure). In larger skin cancers, your doctor may take some skin from another body site to cover the wound and promote healing. This is termed skin grafting. In more advanced cases of skin cancer radiation therapy or chemotherapy (drugs that kill cancer cells) may be used in conjunction with surgery to improve cure rates. Your overall treatment will be individualized based on the type and size of skin cancer, your age, and your overall health.
The single most important thing you can do to lower your risk of skin cancer is to avoid direct sun exposure. Sunlight produces ultraviolet (UV) radiation that can directly damage the cells (DNA) of our skin. People who work outdoors (farmers, construction, boating, outdoor sports) are at the highest risk of developing a skin cancer. The sun's rays are the most powerful between 10 am and 2 pm, so you must be particularly careful during those hours.
If you must be out during the day, wear clothing that covers as much of your skin as possible including a wide-brimmed hat to block the sun from your face, scalp, neck, and ears. In addition to protective clothing, the use of a sunscreen can reflect light away from the skin and provide protection against UV radiation. When selecting a sunscreen, choose one with a Sun Protection Factor (SPF) of 15 or more. Sunscreen products do not completely block the damaging rays but they do allow you to be in the sun longer without getting sunburn.
In addition to being sun-smart, it is critical to recognize early signs of trouble on your skin. The best time to do self-examination is after a shower in front of a full-length mirror. Note any moles, birthmarks, and blemishes. Be on the alert for sores that do not heal or new nodules on the skin. Any mole that changes in size, color, or texture should be carefully examined. If you notice anything new or unusual, see your physician right away. Catching skin cancer early can save your life.
People with any of the factors listed below have a higher risk of developing skin cancer and should be particularly careful of sun exposure.
