Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia. Pernicious anemia is a decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12.

Strep throat is a bacterial infection that can make your throat feel sore and scratchy. Strep throat accounts for only a small portion of sore throats. If untreated, strep throat can cause complications, such as kidney inflammation or rheumatic fever. Rheumatic fever can lead to painful and inflamed joints, a specific type of rash or heart valve damage. Strep throat is most common in children, but it affects people of all ages. If you or your child has signs or symptoms of strep throat, see your doctor for prompt testing and treatment.

Emphysema gradually damages the air sacs (alveoli) in your lungs, making you progressively more short of breath. Emphysema is one of several diseases known collectively as chronic obstructive pulmonary disease Smoking is the leading cause of emphysema. Your lungs' alveoli are clustered like bunches of grapes. In emphysema, the inner walls of the air sacs weaken and eventually rupture — creating one larger air space instead of many small ones. This reduces the surface area of the lungs and, in turn, the amount of oxygen that reaches your bloodstream. When you exhale, the damaged alveoli don't work properly and old air becomes trapped, leaving no room for fresh, oxygen-rich air to enter. Treatment may slow the progression of emphysema, but it can't reverse the damage.

The average time from symptom onset to diagnosis has been reported to be approximately 2 years. Despite recent attempts at increasing the awareness of pulmonary arterial hypertension (PAH), especially associated PAH (APAH), this delay in diagnosis has not changed appreciably in recent years. Early symptoms are nonspecific. Often, neither the patient nor the physician recognizes the presence of the disease, which leads to delays in diagnosis. Complicating matters, idiopathic PAH (IPAH) requires an extensive workup in an attempt to elucidate an identifiable cause of the elevated pulmonary artery pressure. The most common symptoms and their frequency, reported in a national prospective study, are as follows: Dyspnea (60% of patients) Weakness (19%) Recurrent syncope (13%) Additional symptoms include fatigue, lethargy, anorexia, chest pain, and right upper quadrant pain. Cough, hemoptysis, and hoarseness are less common symptoms. Women are more likely to be symptomatic than men.

The virus was first discovered in 1964 when Sir Michael Anthony Epstein and Ms. Yvonne Barr found it in a Burkitt lymphoma cell line. In 1968, the virus was linked to the disease infectious mononucleosis. Infection with Epstein-Barr virus (EBV) is common and usually occurs in childhood or early adulthood. EBV is the cause of infectious mononucleosis (also termed "mono"), an illness associated with fever, sore throat, swollen lymph nodes in the neck, and sometimes an enlarged spleen. It is also known as human herpes virus 4. Although EBV can cause mononucleosis, not everyone infected with the virus will get mononucleosis. Less commonly, EBV can cause more serious disease. Symptoms caused by EBV are usually mild and self-limited, but the virus persists in the body for life. It can be reactivated quietly without causing symptoms and may contaminate saliva. Thus, otherwise healthy people can spread the virus to uninfected people through kissing or sharing

Cytomegalovirus (CMV) is a common virus that can infect almost anyone. Most people don't know they have CMV because it rarely causes symptoms. However, if you're pregnant or have a weakened immune system, CMV is cause for concern. Once infected with CMV, your body retains the virus for life. However, CMV usually remains dormant if you're healthy. CMV spreads from person to person through body fluids, such as blood, saliva, urine, semen and breast milk. CMV spread through breast milk usually doesn't make the baby sick. However, if you are pregnant and develop an active infection, you can pass the virus to your baby.

Genital warts are soft growths that appear on the genitals. Genital warts are a sexually transmitted infection (STI) caused by certain strains of the human papillomavirus (HPV). These skin growths can cause pain, discomfort, and itching. They are especially dangerous for women because some types of HPV can also cause cancer of the cervix and vulva.

Genetic surfactant dysfunction disorders are caused by mutations in genes encoding proteins critical for the production and function of pulmonary surfactant. These rare disorders may produce familial or sporadic lung disease, with clinical presentations ranging from neonatal respiratory failure to childhood- or adult-onset interstitial lung disease. An overview of these disorders is presented in the table.. Interstitial lung diseases in children until recently were categorized by their histologic appearance in a manner similar to that used for adult forms of interstitial lung disease (ILD). In children, the lung histopathology findings associated with desquamative interstitial pneumonitis (DIP) are now known to often result from genetic mechanisms that disrupt normal surfactant production and metabolism. By contrast, DIP in adults is considered to represent a distinct type of ILD, which is strongly associated with cigarette smoking and carries a relatively favorable prognosis [1]. These genetic disorders also result in histopathologic patterns other than DIP, including findings of pulmonary alveolar proteinosis and chronic pneumonitis of infancy. An understanding of the pathogenesis of these disorders permits a mechanistic classification as genetic surfactant dysfunction disorders instead of their previous classification based upon histologic appearance.

Acute leukaemias develop quickly and need to be treated urgently. Chronic leukaemias develop more slowly and may not need to be treated for some time after they are diagnosed. Some forms may not require any treatment. Myeloid leukaemias arise from myeloid stem cells and are characterised by the accumulation of cancerous myeloid cells. Lymphoid leukaemias arise from lymphoid stem cells and are characterised by the accumulation of cancerous lymphoid cells such as B-cells and T-cells. The most common forms of leukaemia in adults are CLL and AML, and the common cancer in children is ALL. Leukaemia is more common in adults.
