Some issues Dr. Mark D. Weissig, MD can help you with:

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.

CPAP Treatment

Continuous positive airway pressure (CPAP) treatment is a medical treatment for people with sleep apnea. Sleep apnea interrupts breathing during sleep, resulting in lapses of oxygen. Lapses of oxygen may in turn lead to severe headaches, heart problems, fatigue, and poor sleep quality. The CPAP device remedies sleep apnea by forcing open the airway with pressurized air, ensuring someone receives enough oxygen while sleeping. The CPAP device is a mask attached to a machine (with a tube) that takes in air from the surrounding room, filters it, and then pressurizes it. The constant flow of pressurized air treats sleep apnea by keeping the tongue and soft palate from obstructing the throat and airway. Benefits of CPAP treatment include:

Improved concentration and focus
Reduced snoring
Lowered risk of heart disease and stroke
Improved mental health

In order to receive a CPAP device, patients must receive a prescription from a physician. Some patients may be asked to complete an overnight sleep study known as a titration study. A titration study monitors patients' sleep using a mask attached to a CPAP machine. The technician may monitor and adjust the CPAP's air pressure throughout the night. The purpose of a titration study is to determine the appropriate air pressure for patients with obstructive sleep apnea (blocked upper airway). Once an appropriate CPAP pressure is identified, physicians or sleep technicians may recommend a specific brand or style of device to the patient for long-term use.

Lung Issues

Every cell in the body requires oxygen to function and produces carbon dioxide as a waste product. In order to keep the body's tissues constantly supplied with fresh oxygen and to keep waste from building up, the lungs pump air in and out, even while sleeping or unaware. Unfortunately, diseases and disorders affecting the lungs are some of the most common medical problems afflicting people around the world. Some of the most common lung problems include asthma, COPD, pneumonia, and lung cancer.

Asthma is a chronic disease where swollen, inflamed airways make it hard to breathe. It is often brought on by specific triggers. While asthma is a common condition, affecting millions of people, it can also be serious and even fatal in severe cases. Treatment involves avoiding triggers and using inhaled corticosteroid medications.

COPD, or Chronic Obstructive Pulmonary Disease, is the name given to two illnesses that both cause difficulty breathing: emphysema and chronic bronchitis. In emphysema, the air sacs of the lungs become damaged, while with bronchitis they become clogged with mucus. COPD is the fourth leading cause of death in the United States. It is almost always caused by breathing irritants into the lungs, such as smoking or heavy pollution.

Pneumonia is a lung infection that can be caused by bacteria, a virus, or fungi. Most healthy people recover from pneumonia in a week or two, but for some people pneumonia can be fatal. There are treatments available for pneumonia, but the best treatment is to prevent getting sick in the first place. People who are at risk should make sure they get a flu shot every year. There is also a vaccine available for the type of bacteria that causes pneumonia.

Lung cancer occurs when abnormal cells inside the lung grow into a tumor, destroying healthy tissue. Because it is so difficult to detect lung cancer in early stages when it has few symptoms, it is the deadliest form of cancer, responsible for the most cancer deaths both in the U.S. and worldwide. Most lung cancer is caused by exposure to tobacco smoke, but between 10-15% of cases are not linked to smoking.

Some problems with the lungs are minor and are not cause for concern. However if symptoms have lasted for a month or more, even if they are minor, it is worth checking with a healthcare professional. A cough, shortness of breath, or excess mucus production that lingers for weeks are all worth getting looked at.
