Bronchoscopy
Bronchoscopy is a diagnostic test that is used to view the airways, throat and larynx. This procedure can also facilitate removal of a growth or obstruction from the airway. Bronchoscopy is useful in diagnosing lung diseases and lung cancer. Any growth in the airways can be treated or removed. Other diagnostic tests such as CBC test, arterial blood gas test and PFT may be prescribed before embarking on bronchoscopy. The secretions in the mouth and airways are dried up with suitable medications. The vocal chords are also numbed. Fluroscope is also used to capture the images on a monitor. Avoid eating or drinking for a few hours prior to a bronchoscopy procedure. There might be blood in the sputum in case of biopsy.
Flexible bronchoscope allows a better view of the smaller airways and permits biopsy procedure too. This is called a transbronchial biopsy. Local anasthesia is often sprayed into the nose and mouth.
Rigid bronchoscope often necessitates the patient to be anesthesized and is resorted to when large samples need to be taken for biopsy and to remove pieces of food or dilating the airway. Use of laser is possible for removal for obstructions.
Abnormal results of bronchoscopy may be indicative of lung cancer, tumor, enlarged lymph nodes, ulceration or abnormality in the bronchial wall. Bronchoscopy is prescibed in cases where the patient coughs up blood or chest x-ray shows abnormal findings. If a person has inhaled a foreign body into the lung, bronchoscopy can help in removing it.
Tuberculosis
Tuberculosis, TB or Pulmonary tuberculosis is a bacterial contagious disease caused by Mycobacterium tuberculosis. Persons with weakened immune system, infants and elderly people are at higher risk for tuberculosis. You can be at greater risk if you are in frequent contact with persons suffering TB. Poor nutrition and sanitation contribute to the risk factor. Many drug-resistant strains of TB have made it more difficult to treat the disease. Pulmonary tuberculosis shows up with symptoms like fatigue, fever, cough with mucus and blood, chest pain, difficulty in breathing and unexplained weight loss. A person suffering TB will have enlarged lymph nodes and pleural effusion. Bronchoscopy, chest x-ray and sputum culture can aid diagnosis of pulmonary tuberculosis. Pulmonary TB is treated with Isoniazid, Rifampin, Ethambutol, Streptomycin or Moxifloxacin. Treatment usually lasts for 6 months or longer.
Extra pulmonary tuberculosis or Miliary tuberculosis
Tuberculosis can also affect other parts of the body such as bones, lymphatic system, central nervous system and genital or urinary system. Disseminated tuberculosis or Miliary tuberculosis is a contagious bacterial infection that has spread from the lungs to other parts of the body through the blood or lymph system. This type of TB can also affect the larynx, skin and pericardium too.
Pneumonia
In most cases, pneumonia is noticed after an upper respiratory illness. When there is infection in the lung tissue, pneumonia occurs. This disease can be caused by either virus, bacteria, fungi or parasites. Pneumonia caused by virus appears gradually and may not be as severe as when caused by bacteria. The streptococcus bacteria, known as pneumococcus, is the main cause of pneumonia. adenoviruses, rhinovirus, influenza virus, respiratory syncytial virus (RSV), and parainfluenza virus are among the viruses that can cause pneumonia. Weak and elderly people are more at risk for contracting pneumonia. Persons with weakened immune systems or have had their spleen removed are more susceptible for pneumonia.
The disease is contagious and spreads through touching used handkerchiefs and sharing utensils.
Symptoms of pnemonia include fever, cough and chest pain. There is labored breathing and abdominal pain. Wheezing is noticed in cases of viral pneumonia. A patient suffering from pneumonia may develop bluish or grayish palor on the lips and fingertips. A case of bacterial pneumonia can take about a fortnight to recover while viral pneumonia takes longer. Pneumonia can be mild or life threatening.
Pneumonia is detected during a physical examination. Chest xrays and CT scan can help confirm the presence of pneumonia and throw light on the extent and location of the infection. Blood tests and phlegm sample can detect presence of virus or bacteria. Bronchoscopy allows a doctor to examine the patient's breathing passages. Antibiotics such as penicillin, amoxicillin and clavulanic acid are prescribed to treat pneumonia. Macrolide antibiotics such as erythromycin, azithromycin and clarithromycin are prescribed to those suffering from pneumonia. Vaccines against Haemophilus influenzae and pertussis are part of the routine immunization schedule for children.
