Some issues Dr. Ahmareen H. Khan, MD can help you with:

Asthma

Asthma is a chronic lung disease where the tissue and airways of the lungs become extremely sensitive to certain substances. When these substances are breathed in, the lungs become inflamed. The muscles around the airways tighten and squeeze the lungs, and passages within the lungs swell and tighten. The airways themselves produce mucus, which further clogs the tightened, swollen airways. A person having an asthma attack finds it very difficult to breathe, and a severe attack can even be fatal.

Asthma affects people of all ages, but people with asthma are most often diagnosed as children. Symptoms can include wheezing, a tight feeling in the chest, shortness of breath, and coughing. Some people have mild symptoms all the time, and some people have no symptoms at all, but everyone with asthma is susceptible to occasional severe attacks or flare-ups of symptoms when they are exposed to triggers. Triggers vary widely but can include:

Allergens (dust mites, pet fur, mold, pollen, grass)
Irritants (smoke, pollution, dust, chemicals)
Viral infections
Physical activity, especially outdoors
Certain medications or chemicals in foods (aspirin, sulfites)

Treatment for most asthma patients involves three steps. Patients learn what their asthma triggers are and avoid them. They take a daily control medication, usually an inhaled corticosteroid, to reduce inflammation in the lungs. Also, they have rescue medication with them at all times to take in case of a severe attack. These quick-acting inhaled medications relax the muscles around the airways and allow the lungs to open up for air.

There is no cure for asthma, but with treatment it should not interfere with daily life and activities.

Bronchoscopy

Bronchoscopy is a procedure in which a thin tube with a camera, called a bronchoscope, is inserted in the mouth or nose and slowly advanced to the lungs. This allows doctors to see the respiratory tract, which includes the throat, larynx (voice box), trachea (windpipe), bronchi (airways), and lungs. Doctors may recommend those who have or show signs of lung problems - for example, lung cancer or difficulty breathing - to undergo a bronchoscopy.

In performing a diagnostic bronchoscopy, doctors may only wish to visualize the respiratory tract, or doctors may also collect samples of tissue or fluid. The samples can help diagnose patients' conditions or, if patients have cancer, they can be used for staging purposes. One method for sample collection is bronchoalveolar lavage. In a bronchoalveolar lavage, doctors inject saline (salt water) through the bronchoscope and then suction it out of the airways. The washout collected is tested for lung disorders. Doctors can also insert a biopsy tool to collect tissue or mucus samples. The following are biopsies that can be performed by bronchoscopy:

Brush biopsy, which uses a brush to collect samples.
Endobronchial biopsy, which uses the bronchoscope to guide forceps to sample lung tissue.
Transbronchial biopsy, which uses forceps and image guidance - such as X-rays, CT scans, or fluoroscopy - to sample lung tissue.
Transbronchial fine needle aspiration (TBNA), which uses a small needle to take samples of the lymph nodes or lungs.

For visualization, bronchoscopy can be done alone, or it can be combined with ultrasound. Endobronchial ultrasound (EBUS) allows real-time imaging of the airway and is used for diagnosing and staging lung cancer, as well as for determining where the cancer has spread. EBUS can be performed with TBNA, a procedure known as endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).

Doctors can also use bronchoscopy as a treatment for lung problems. For example, if a foreign body is trapped in the airway, doctors can insert forceps through the bronchoscope to remove it. If the airway has become narrowed - which may occur if patients have an infection, cancer, or some other inflammatory issue - bronchoscopy can be used to place a device called a stent in the area of constriction. The stent will keep the airway open, allowing the patient to breathe properly.

During a bronchoscopy, patients will be given medication (sedative) to help them relax. If it is only a diagnostic bronchoscopy, patients will be kept awake, but if the bronchoscopy is for therapeutic purposes, patients will be put to sleep by general anesthesia. After the procedure, patients will need to stay in the hospital for a few hours. They will not be able to eat or drink for about 2 hours. Some patients may experience discomfort, such as a sore throat or pain while swallowing. Throat lozenges and gargling may help alleviate these symptoms, which should go away after a few days. Patients will need to have someone drive them home once their doctor determines that they are ready.
