Pneumococcal pneumonia is a type of bacterial pneumonia that is caused by Streptococcus pneumoniae (pneumococcus). It is the most common bacterial pneumonia found in adults, the most common type of community-acquired pneumonia, and one of the common types of pneumococcal infection. The estimated number of Americans with pneumococcal pneumonia is 900,000 annually, with almost 400,000 cases hospitalized and fatalities accounting for 5-7% of these cases. Symptoms
The symptoms of pneumococcal pneumonia can occur suddenly, presenting as a severe chill, followed by a severe fever, cough, shortness of breath, rapid breathing, and chest pains. Other symptoms like nausea, vomiting, headache, fatigue, and muscle aches could also accompany initial symptoms. The coughing can occasionally produce rusty or blood-streaked sputum. In 25% of cases, a parapneumonic effusion may occur. Chest X-rays will typically show lobar consolidation or patchy infiltrates. Treatment
In most cases, once pneumococcal pneumonia has been identified, doctors will prescribe antibiotics. These antibiotics usually help alleviate and eliminate symptoms between 12 and 36 hours after the initial dose. Despite most antibiotics effectiveness in treating the disease, sometimes the bacteria can resist the antibiotics, causing symptoms to worsen. Age and health of the infected patient can also contribute to the effectiveness of the antibiotics. A vaccine has been developed for the prevention of pneumococcal pneumonia, recommended to children under age five as well as adults over the age of 65.
Undifferentiated connective tissue disease (UCTD) is a disease in which the body mistakenly attacks its own tissues. It is diagnosed when there is evidence of an existing autoimmune condition which does not meet the criteria for any specific autoimmune disease, such as systemic lupus erythematosus or scleroderma. Latent lupus and incomplete lupus are alternative terms that have been used to describe this condition.The term is sometimes used interchangeably with mixed connective tissue disease, an overlap syndrome. However, MCTD is thought by some researchers to be a clinically distinct entity and is strongly associated with the presence of high titers of ribonucleoprotein (RNP) antibodies.It is estimated that up to 25 percent of people with systemic autoimmune disease could be considered to have UCTD. Signs and symptoms
Disease presentation varies widely from patient to patient, as UCTD is by definition nonspecific. Symptoms typically include constitutional complaints that are common to connective tissue diseases such as fatigue, a general sense of feeling unwell, and fever. Other symptoms associated with UCTD include:
dry eyes
dry mouth
hair loss
joint inflammation
joint pain
oral ulcers
positive ANA test
raynauds phenomenon
sun sensitive rashClinical presentation in some people diagnosed with UCTD may show: 
a decrease in white blood cell count in the blood
anemia
abnormal nerve sensations in the extremities
inflammation of the lining of the heart and/or lungs
a decrease in platelet countLung involvement, such as nonspecific interstitial pneumonia, is a possible disease complication. Diagnosis
There is no official diagnostic criteria for UCTD. Diagnostic testing generally aims to determine whether a patient has a definite or undifferentiated connective tissue disease.
