Pneumonia : Pneumonia is an inflammatory condition of the lung affecting primarily the microscopic air sacs known as alveoli. It is usually caused by infection with viruses or bacteria and less commonly other microorganisms, certain drugs and other conditions such as autoimmune diseases. Typical symptoms include a cough, chest pain, fever, and difficulty breathing. Patients with pneumonia are treated with amoxicillin, doxycycline, clarithromycin or oral macrolide antibiotics (azithromycin, clarithromycin, or erythromycin).Patients with other serious illnesses, such as heart disease, chronic obstructive pulmonary disease, or emphysema, kidney disease, or diabetes are often given more powerful and/or higher dose antibiotics like third- and fourth-generation cephalosporins, carbapenems, fluoroquinolones, aminoglycosides, and vancomycin. In addition to antibiotics, treatment includes: proper diet and oxygen to increase oxygen in the blood when needed. In some patients, medication to ease chest pain and to provide relief from violent cough may be necessary.


Bronchitis : Bronchitis is an inflammation of the mucous membranes of the bronchi (the larger and medium-sized airways that carry airflow from the trachea into the more distal parts of the lung parenchyma) Treatment Conventional treatment for acute bronchitis may consist of simple measures such as getting plenty of rest, drinking lots of fluids, avoiding smoke and fumes, and possibly getting a prescription for an inhaled bronchodilator and/or cough syrup. In some cases of chronic bronchitis, oral steroids to reduce inflammation and/or supplemental oxygen may be necessary.


Tonsillitis : Tonsillitis is inflammation (swelling) of the tonsils. Tonsillitis is inflammation (swelling) of the tonsils most commonly caused by viral or bacterial infection. Symptoms may include sore throat and fever. When caused by a bacterium belonging to the group A streptococcus, it is typically referred to as strep throat. The overwhelming majority of people recover completely, with or without medication. In 40%, symptoms will resolve in three days, and within one week in 85% of people, regardless of whether streptococcal infection is present or not. Causes The tonsils are lymph nodes in the back of the mouth and top of the throat. They normally help to filter out bacteria and other germs to prevent infection in the body. A bacterial or viral infection can cause tonsillitis. Strep throat is a common cause. The infection may also be seen in other parts of the throat. One such infection is called pharyngitis. Tonsillitis is very common, especially in children. Symptoms • Difficulty swallowing • Ear pain • Fever, chills • Headache • Sore throat - lasts longer than 48 hours and may be severe • Tenderness of the jaw and throat Treatment Treatments to reduce the discomfort from tonsillitis symptoms include: • pain relief, anti-inflammatory, fever reducing medications (paracetamol/acetaminophen and/or ibuprofen) • sore throat relief (warm salt water gargle, lozenges, dissolved aspirin gargle (aspirin is an anti inflammatory, do not take any other anti inflammatory drugs with this method), and iced/cold liquids) If the tonsillitis is caused by group A streptococcus, then antibiotics are useful with penicillin or amoxicillin being primary choices. Cephalosporins and macrolides are considered good alternatives to penicillin in the acute setting. A macrolide such as erythromycin is used for people allergic to penicillin. Individuals who fail penicillin therapy may respond to treatment effective against beta-lactamase producing bacteria such as clindamycin or amoxicillin-clavulanate. Aerobic and anaerobic beta lactamase producing bacteria that reside in the tonsillar tissues can "shield" group A streptococcus from penicillins. When tonsillitis is caused by a virus, the length of illness depends on which virus is involved. Usually, a complete recovery is made within one week; however, symptoms may last for up to two weeks. Chronic cases may be treated with tonsillectomy (surgical removal of tonsils) as a choice for treatment. The following tips may help your throat feel better: • Drink cold liquids or suck on popsicles • Drink fluids, especially warm (not hot), bland fluids • Gargle with warm salt water • Suck on lozenges (containing benzocaine or similar ingredients) to reduce pain (these should not be used in young children because of the choking risk) • Take over-the-counter medications, such as acetaminophen (Tylenol) or ibuprofen to reduce pain and fever. Do NOT give a child aspirin. Aspirin has been linked to Reye syndrome. Some people who have repeated infections may need surgery to remove the tonsils (tonsillectomy)


Pharyngitis : Pharyngitis is defined as an infection or irritation of the pharynx or tonsils. The etiology is usually infectious, with most cases being of viral origin and most bacterial cases attributable to group A streptococci (GAS). Other causes include allergy, trauma, toxins, and neoplasia. GAS pharyngitis is usually a self-limited disease, and most signs and symptoms resolve spontaneously in 3-4 days. If administered early, antibiotics can shorten the duration of the illness by up to 1 day, but the main reason they are given is for prevention of acute rheumatic fever. Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting. Antibiotics are indicated for clinically suspected and culture or antigen-verified GAS infection. Common antibiotics for pharyngitis include amoxicillin,cephelexin, azithromycin,erythromycin, ceftriaxone etc. Steroids (such as dexamethasone) have been found to be useful for severe pharyngitis. Analgesics such as NSAIDs and acetaminophen can help reduce the pain associated with a sore throat.
