Conditions We Treat

Allergic Rhinitis

Allergic Rhinitis

Allergic rhinitis, commonly called hay fever, is an inflammatory condition that results in a combination of symptoms including sneezing, nasal congestion, itching, runny nose, and/or post-nasal drip. It is caused when your immune system becomes sensitized to and then overreacts to a substance which is typically harmless in nature. Based on physician diagnosis, allergic rhinitis affects approximately 15% of people in the United States. However, self-reported diagnosis estimates the prevalence to be as high as 30% of the US population. Allergic rhinitis commonly contributes to missed or unproductive time at work and school, sleep problems, and decreased involvement in outdoor activities. Some studies have even found allergic rhinitis symptoms to worsen or contribute to depression, attention deficit, and memory or learning problems.

The symptoms of allergic rhinitis are similar to those of a cold but last longer than 7-10 days. Symptoms can include sneezing, runny nose, stuffy nose, post-nasal drip, itchy eyes, watery eyes, itchy nose, and dark circles under the eyes. Having allergic rhinitis can increase the probability of developing asthma. Up to 40% of people with allergic rhinitis have asthma. The main triggers for allergic rhinitis are pollen from trees, weed, and grasses, in addition to molds, cockroach, dust mites, and animal dander. Some allergens cause symptoms only during certain seasons and are referred to as seasonal allergens. Some cause symptoms year-round and are called perennial allergens.

There are many treatment options for allergic rhinitis. The physicians at Park Cities Allergy & Asthma will develop a treatment plan customized to work best for you and your needs.

Anaphylaxis

Anaphylaxis

Anaphylaxis is a very serious and potentially life-threatening allergic reaction. It can occur within seconds of exposure. Symptoms can include dizziness or fainting, difficulty breathing, wheezing, swelling, hives, itching, abdominal pain, nausea, vomiting, and diarrhea. The most common causes of anaphylaxis are food allergies, insect allergies (wasps, hornets, bees, fire ants), medication allergies, and latex.

Anaphylaxis requires immediate treatment including prompt administration of epinephrine. Avoidance of the trigger going forward is vital. The physicians at Park Cities Allergy & Asthma can help determine the cause of anaphylaxis and how to prevent another episode in the future.

Drug allergy

Drug Allergy

A drug allergy is an abnormal immune reaction to a medication. Symptoms commonly include rash, fever, and hives. Symptoms can also include difficulty breathing, wheezing, itching, swelling, abdominal pain, vomiting, and loss of consciousness. Any medication including over the counter medications, herbals, supplements, can cause allergic reactions, but some medications are more likely to than others. The most common medications to cause allergic reactions are penicillin and similar antibiotics, sulfa drugs, Non-steroidal anti-inflammatory drugs (such as aspirin and ibuprofen), anti-convulsants, and chemotherapy drugs.

Approximately 10% of the population reports a penicillin allergy, but over 90% of these individuals are not truly allergic. Even in those with a true penicillin allergy, 50% of these people will lose their tendency within 5 years. There is an increased risk of drug resistant infections and longer hospitalizations in patients labeled penicillin allergic. Thus, it is to your advantage to know if you are allergic to penicillin. Luckily, there is an easy and safe test for penicillin allergy.

Patients who may have previously had an allergic reaction to penicillin may no longer be sensitive to the medication and may benefit from a penicillin allergy test if they require penicillin for medical treatment. During an initial consultation, our physicians will evaluate your medical and penicillin sensitivity history, and thereby determine candidacy for further testing.

At a subsequent visit, if deemed eligible, skin prick tests and intradermal tests with standardized reagents will be performed, and should these be negative, an open challenge with an oral form of penicillin will be performed under close physician supervision.

Food allergy

Food Allergy

Approximately 1 in 13 children and 1 in 10 adults in the United States have food allergies. A food allergy is an abnormal response to a food triggered by the body’s immune system. Symptoms can include rash, hives, itching, vomiting, diarrhea, trouble breathing, wheezing, and even loss of consciousness. Food allergic reactions can be very serious, and in some cases, lead to death. Therefore, if you have a food allergy, it is extremely important to know what the trigger food is and how to avoid it. In the United States, 8 foods cause over 90% of food allergic reactions. These include peanut, tree nuts, wheat, soy, egg, cow’s milk, shellfish, and finned fish.

There are other food allergic conditions including Eosinophilic Esophagitis (EoE), Food Protein-Induced Enterocolitis Syndrome (referred to as FPIES), and Oral Allergy syndrome.
Eosinophilic Esophagitis is an allergic condition causing inflammation of the esophagus. The esophagus is the tube that sends food from the throat to the stomach. Most research suggests that the leading cause of EoE is an allergy or a sensitivity to particular proteins found in foods.

FPIES is a severe condition causing vomiting and diarrhea. In some cases, symptoms can progress to dehydration and shock brought on by low blood pressure and poor blood circulation. Much like other food allergies, FPIES allergic reactions are triggered by ingesting a food allergen. Although any food can be a trigger, the most common culprits include milk, soy and grains. FPIES often develops in infancy, usually when a baby is introduced to solid food or formula.

Oral Allergy Syndrome, also known as pollen-food allergy syndrome, is caused by cross-reacting allergens found in both pollen and raw fruits, vegetables, or some tree nuts. Symptoms of oral allergy syndrome include itchy mouth, scratchy throat, or swelling of the lips, mouth, tongue, and throat. Symptoms do not normally progress, and it is very rare that people develop symptoms away from the mouth, although it has been reported in very small percentages.

Sometimes, a reaction to a food is not an allergy but is another type of reaction called “food intolerance”. The difference is that a food allergy is caused by the immune system and can be life threatening. A food intolerance is not mediated by the immune system. Food intolerances are more common than food allergies.

Immunodeficiency

Immune Deficiency

An immune deficiency is caused when part of the immune system is absent or not functioning properly. When the deficiency is secondary to hereditary or genetic causes, it is called a primary immune deficiency. When the deficiency is caused by other reasons such as malnutrition, chemotherapy, HIV, etc., the deficiency is called a secondary immune deficiency. Signs of an immune deficiency include recurrent, unusual, or difficult to treat infections, poor growth or weight gain, recurrent deep abscesses, family history of primary immune deficiency, chronic diarrhea, persistent thrush or other fungal infections, or need for IV antibiotics.

If you are experiencing recurrent infections, the physicians at Park Cities Allergy & Asthma can determine the cause and help you live a healthier life.

Atopic dermatitis

Atopic Dermatitis

Atopic dermatitis, commonly called eczema, is caused by skin barrier dysfunction which results in dryness and inflammation. It presents as dry, red, itchy skin. It is very common affecting 1 in 5 infants and 1 in 50 adults. Children who have a family history of allergic disease such as asthma or hay fever or more likely to develop atopic dermatitis. Atopic dermatitis is considered to the best first step in the atopic march. The atopic march involves the development of allergic conditions including eczema, food allergy, allergic rhinitis, and asthma, typically in that order. Up to 80% of children with eczema will go on to develop asthma and/or allergic rhinitis.

Hives

Hives

Urticaria is the medical term for hives. Hives are red whelps or bumps that are extremely itchy. About 20% of the population will experience hives at some point in their lives. Hives are considered acute if they last no longer than 6 weeks and chronic if they last longer than 6 weeks. Acute hives are often caused by medication allergy, food allergy, or insect allergy. Acute hives can be caused by non-allergic triggers such as infections, heat, cold, and exercise. Chronic hives are rarely caused by specific triggers.

The allergists at Park Cities Allergy & Asthma Care can help determine the cause of hives and the best way to manage them.

Angioedema

Angioedema

Angioedema is swelling of the tissue beneath the surface of the skin. It commonly occurs with hives but can occur on its own. It presents as swelling of the eyes, lips, tongue, hand, and/or feet. Swelling can also occur in the abdomen. If swelling of the throat develops, this can be life threatening and requires immediate medical attention. Swelling can be related to an allergic reaction, medications, or hereditary.

Your allergist and Park Cities Allergy & Asthma can determine the underlying mechanism of the swelling to help determine the best treatment.

Contact dermatitis

Contact Dermatitis

Contact dermatitis is a rash that occurs due to direct contact of the skin with an allergen. The contact will produce a red, bumpy, itchy rash. Some of the most common culprits of contact dermatitis or poison ivy and nickel. If you have a nickel allergy, you can develop a rash after wearing jewelry that contains even a small amount of nickel. It is possible to become allergic to ingredient in your personal hygiene products such as soap, shampoo, make-up, and sunscreen.

The allergists at Park Cities Allergy & Asthma Care can help determine your contact allergens through patch testing.

Asthma

Asthma

Asthma is a chronic airway disease characterized by inflammation and swelling of the walls of your airways, and may be triggered by things that you are allergic to or find irritating. When the airways react, they get narrower, and this causes symptoms like wheezing, coughing, chest tightness, and trouble breathing, especially at night and in the early morning. Asthma cannot be cured, but most people with asthma can control it so that they have few and infrequent symptoms and can live active lives.

Chronic cough

Chronic Cough

A chronic cough is a cough that lasts longer than 8 weeks in an adult and 4 weeks in a child. Chronic cough can affect sleep, work/school performance, and social activities. The most common reasons for a chronic cough are asthma, post nasal drip, and reflux.

Your allergist at Park Cities Allergy & Asthma can help pinpoint the cause of the cough and recommend treatment for resolution.

"Dr. Clarke is amazing! For years I struggled with allergies and asthma, which would always end up in pneumonia and hospital visits. The day I met Dr. Clarke my life changed. She spent the time listening and testing, then came up with a treatment plan that fit my lifestyle, not telling me I had to change it. When issues came up she found the best way to treat them quickly and effectively. She genuinely cares about her patients well being. For me, she is one of the best doctor’s I’ve had, and I would recommend her to anyone who struggles with asthma or allergies. I no longer dread “allergy season,” and can finally breath! She’s my medical hero for sure!!"

"I HIGHLY recommend Park Cities Allergy & Asthma! I originally went in for food allergy testing but after talking with Dr. Schroeder, we decided to move forward with an environmental allergy test. This test was done the same day! It was quick and easy. The staff is super professional and after you've been there once they address you by name when you walk in. Excellent customer service! Highly recommend for anyone seeking questions to their allergy/asthma issues."

"Dr Schroeder is the best. I’ve had lots of allergy issues in the last few years and she is so understanding, supportive and available. I’ve a had more than one situation where I had severe allergy attacks after hours and Dr Schroeder has answered calls and texts on her cell phone - even coaching me through administering an Epi-Pen. Office staff is friendly and keep things running smoothly. Office itself is beautiful - clean and spa-like. I’ve also undergone immunotherapy with them and have seen an incredible difference with my seasonal allergies. Highly recommend for allergy treatment and immunotherapy."
- Katherine
"The experience here was as much spa as it was medical treatment. Came in with severe allergies and Dr: Schroeder spent what felt like hours with me. Full panel test last week and returned for rush immunology today. Everyone was professional, compassionate, patient with my apprehension of needles, and encouraging. Loved the day I spent here in their most calming environment. Looking forward to beating these allergies and continuing to be a good cat 🐈 dad! ❤️"
