What Is Tonsillitis?
What Is Tonsillitis?
Tonsils
are the two lymph nodes located on each side of the back of your
throat. They function as a defense mechanism, helping to prevent
infection from entering the rest of your body. When the tonsils
themselves become infected, the condition is called tonsillitis.
Tonsillitis can occur at any age and is a common childhood ailment. It is most often diagnosed in children from preschool age through their mid teens. Symptoms include a sore throat, swollen tonsils, and fever.
This condition can be caused by a variety of common viruses and bacteria and is contagious. If left untreated, tonsillitis caused by strep throat (Streptococcus bacteria) can lead to serious complications.
Tonsillitis is easily diagnosed and treated. Symptoms usually fully resolve within seven to 10 days.

Whooping Cough (Pertussis)
Whooping Cough
Whooping cough is a serious respiratory infection caused by a type of bacteria called Bordetella pertussis.
The infection causes violent, uncontrollable coughing that can make it
difficult to breathe. While whooping cough can affect people at any
age, it can be deadly for infants and young children.
Before a vaccine was available, whooping cough caused approximately 10,000 deaths per year in the U.S. According to KidsHealth, whooping cough is now responsible for fewer than 30 deaths each year. (KidsHealth). Don’t let your guard down – there are still one million new cases reported in adults and adolescents each year.

What Is Pneumonia?
What Is Pneumonia?
Pneumonia is an infection in one or both lungs. The infection may be
caused by fungi, bacteria, or viruses. Pneumonia causes inflammation
in your lung’s
air sacs, also referred to as alveoli. The alveoli fill with fluid or
pus, making it difficult to breathe. Symptoms of pneumonia can range
from mild to life threatening. In fact, pneumonia causes more deaths
worldwide than any other illness. The severity of pneumonia usually
depends on the cause of the inflammation or by the type of organism
causing the infection, a person’s age, and their general health.
The Types of Pneumonia, Grouped by Causes
There are five major types of pneumonia. They are:
Less common types of pneumonia can also be serious. Pneumonia can be caused by inhaling food, dust, liquid, gas, and by various fungi.
Bacterial Pneumonia
Bacterial pneumonia can affect anyone at any age. It can develop on its own or after a serious cold or flu. The most common cause of bacterial pneumonia is streptococcus pneumoniae. Bacterial pneumonia can also be caused by Chlamydophila pneumonia or legionella pneumophila. Pneumocystis jiroveci pneumonia is sometimes seen in those who have weak immune systems, due to illnesses like AIDS or cancer.Viral Pneumonia
In most cases, respiratory viruses can cause pneumonia, especially in young children and the elderly. Pneumonia is usually not serious and lasts a short time. However, the flu virus can cause viral pneumonia to be severe or fatal. It’s especially harmful to pregnant women or individuals with heart or lung issues. Invading bacteria can cause complications with viral pneumonia.Mycoplasma Pneumonia
Mycoplasmas are not viruses or bacteria, but they have traits common to both. They are the smallest agents of disease that affect humans. Mycoplasmas generally cause mild cases of pneumonia, most often in older children and young adults.Other Types of Pneumonia
Many additional types of pneumonia affect immune-compromised individuals. Tuberculosis and pneumocystis carinii pneumonia (PCP) generally affect persons with AIDS. In fact, PCP can be one of the first signs of illness in people with AIDS.Less common types of pneumonia can also be serious. Pneumonia can be caused by inhaling food, dust, liquid, gas, and by various fungi.
Who Is at Risk for Developing Pneumonia?
No one is immune to pneumonia, but there are certain factors that can raise your risks:
- previous stroke or problems swallowing: People who have had a stroke, have problems swallowing, or are bedridden can easily develop pneumonia.
- age: Infants from birth to age two are at risk for pneumonia, as are individuals age 65 or older.
- weakened immune system: This includes people who take medications (steroid drugs and anti-cancer drugs) that weaken the immune system and people with HIV, AIDS, or cancer.
- drug abuse: This includes excessive alcohol consumption and smoking.
- certain medical conditions: Asthma, cystic fibrosis, diabetes, and heart failure raise your risks for pneumonia.
What Are the Symptoms of Pneumonia?
The general symptoms of bacterial pneumonia can develop quickly and may include:
- chest pain
- shaking chills
- fever
- dry cough
- muscle aches
- nausea/vomiting
- rapid breathing
- rapid heartbeat
- difficulty breathing
- skin with bluish tone (from lack of oxygen)
- blood in sputum (coughed-up mucus)
- labored breathing
- high fever (103 °F or higher)
- confusion
- rapid heartbeat
How Is Pneumonia Diagnosed?
Pneumonia can be easily overlooked as the cause of an illness
because it often resembles a cold or the flu. However, it usually lasts
longer and symptoms seem more severe than these other conditions.
Detailed Patient History
To determine whether or not a patient has pneumonia, doctors generally inquire about a patient’s signs and symptoms. Questions they may include:- What are your symptoms and when did they begin?
- What were your recent travels and activities?
- What was your recent exposure to animals?
- What was your recent exposure to individuals who are sick?
- What are your past and current medical issues?
- What medications are you currently taking?
- What is your smoking history?
- Have you recently had any vaccinations or illnesses?
Physical Exam
Crackling and bubbling sounds in the chest during inhalation are usually indicators of pneumonia. Wheezing may also be present. Additionally, your doctor may have trouble hearing normal breathing sounds in different areas of the chest.Diagnostic Tests
Chest X-rays can be used to determine if infection is present in your lungs. However, chest X-rays won’t show your type of pneumonia. Blood tests can provide a better picture of the type of pneumonia. Also, blood tests are necessary to see if the infection is in your bloodstream.Other Tests
Additional tests that may be required include:- Chest computed tomography (CT scan): A CT scan is similar to an X-ray, but the pictures provided by this method are highly detailed. This painless test provides a clear and precise picture of the chest and lungs.
- Sputum test: This test will examine the sputum (the mucus you cough up) to determine what type of pneumonia is present.
- Pleural fluid test: If there is fluid apparent in the pleural space (the space between the tissue that covers the outside of your lungs and the inside of your chest cavity), a fluid sample can be taken to help determine if the pneumonia is bacterial or viral.
- Pulse oximetry: This test measures the level of oxygen blood saturation by attaching a small sensor to your finger. Pneumonia can prevent normal oxygenation of blood.
- Bronchoscopy: When antibiotics fail, this method is used to view the airways inside the lungs to determine if blocked airways are contributing to the pneumonia.
How Is Pneumonia Treated?
The type of treatment prescribed for pneumonia primarily depends on
what type of pneumonia is present and its severity. In many cases,
pneumonia can be treated at home.
General Treatment
The typical treatment plan for pneumonia includes taking all prescribed medications and participating in follow-up care. A chest x-ray may be ordered to ensure your pneumonia has been successfully treated.Treating Bacterial Pneumonia
Antibiotics are used to treat this type of pneumonia. Antibiotics should be taken as directed. If antibiotics are ceased before treatment is complete, the pneumonia may return. Most people will improve after one to three days of treatment.Treating Viral Pneumonia
Antibiotics are useless if a virus is the cause of pneumonia. However, antiviral drugs can help treat the condition. Symptoms usually improve within one to three weeks.Can Pneumonia Be Prevented?
Allergic Rhinitis
What Is Allergic Rhinitis?
Allergic rhinitis, also called hay fever, is the group of
uncomfortable symptoms that occur when your body is exposed to a
specific allergen. An allergen is a typically harmless substance, such
as grass or dust, which causes an allergic reaction. Pollen is the most
common allergen for most people.
When your body comes into contact with an allergen, it releases histamine. This is a natural chemical that is actually intended to defend the body from the allergen. However, this chemical causes many uncomfortable symptoms (allergic rhinitis) that include runny nose, sneezing, and itchy eyes.
This condition can interfere with your everyday quality of life, so it is important to find treatment.

Asthma
Asthma is an inflammatory disease of the lungs.
It makes breathing difficult and brings on attacks of coughing, wheezing,
tightness in the chest and shortness of breath. According to the Centers for
Disease Control and Prevention (CDC), approximately 25
million Americans suffer from asthma. It’s the most common chronic condition
among American children. About one in every 10 children has asthma.
To understand asthma, you need to understand a little about
what happens when you breathe. Normally, with every breath you take, air goes
through your nose and down into your throat, eventually making it to your
lungs. There are lots of small air passages in your lungs that help deliver
oxygen from the air into your bloodstream. Asthma symptoms occur when the
lining of these air passages swell and the muscles around them tighten. Mucus then
fills the airways, further reducing the amount of air that can pass through. These
conditions then bring on an asthma “attack” — the coughing and tightness
typical of asthma.
Cough
Cough
A cough is a common reflex action that aims to clear the throat of
mucus or foreign irritants. Coughing to clear the throat is typically
an infrequent action, although there are a number of other conditions
that can cause more frequent bouts of coughing.
In general, a cough that lasts for less than three weeks is known as an acute cough.
A cough that lasts between three weeks and eight weeks, improving by the end of the period, is known as a sabacute cough.
A persistent cough that lasts for over eight weeks is known as a chronic cough.
Most coughs will clear up, or at least significantly improve, within two weeks. If you cough up blood or have a “barking” cough, consult with a doctor. Any cough that has not improved after a few weeks may be serious and you should see a doctor.
