    Over the past two decades, there has been a growing trend for the care of the hospitalized patient to be assumed by physicians who care only for patients in the inpatient setting, and who do not have an outpatient medical practice. These physicians have come to be known as "hospitalists", and their area of practice as "hospital medicine". Hospitalists are a departure from the old style of practice, in which the primary care physician (PCP) cared for their seriously ill patients in the hospital while still maintaining a busy outpatient practice. Because of the increasing complexity of modern medicine, and due to a variety of economic pressures, the trend now is for physicians in primary care specialties to focus their practice on either outpatient or inpatient care, but not both.

    Congestive heart failure can be simply described as the inability of the heart to meet the metabolic demands of the body. The heart functions as a pump to deliver oxygen and nutrients to the tissues. Failure of the pump to deliver nutrition to the tissues stimulates a number of compensatory responses in an effort to improve tissue perfusion. These responses result in the clinical symptoms and signs associated with the heart failure syndromes-shortness of breath, rapid heartbeat, and fluid retention.

    Acute respiratory distress syndrome (ARDS) was first described in 1967 by Ashbaugh, who described a syndrome of severe respiratory failure associated with pulmonary infiltrates, similar to infant hyaline membrane disease.

    Anterior Cruciate Ligament Injury (ACLI) is most often a result of low-velocity, noncontact, deceleration injuries and contact injuries with a rotational component. Contact sports also may produce injury to the anterior cruciate ligament (ACL) secondary to twisting, valgus stress, or hyperextension all directly related to contact or collision.

    Some of the most abstract medical occurrences that may also prove to be legally challenging are transient disorders of awareness. The very nature of their transient occurrence often results in an absence of objective laboratory or examination abnormalities. Since these conditions result in an alteration of the patient's awareness, there may also be inadequate historical information to assist in diagnosis. Yet, these disorders can have very significant consequences that range from a loss of one's driving privileges or job to the participation in a criminal event. The two most common causes of altered awareness are seizures and reduced blood flow to the brain.

    There are many wrist and hand symptoms related to the multiple tunnels that tendons, nerves, and blood vessels pass through. Wherever there is a "crease" in one's wrist, palm, or fingers on the flexor/volar side, there is a tunnel that these structures must pass through. These tunnels are usually soft transverse tissue bands that keep the tendons from bowstringing as they pass from forearm to fingers, as we use our hands in grasp and function.

    Almost every American from eighteen to eighty years of age has heard enough about LASIK to understand on a basic level what it is and how it works.

The vast majority of these procedures are successful, but unwanted side effects and/or suboptimal results can occur in a small percentage of patients. Below is a discussion of the essential elements in the pre-operative evaluation of a patient being considered for LASIK.

    Crude Oil has been pouring into the Gulf of Mexico and is causing numerous and significant health issues for children, pregnant mothers, and adults. Exposure occurs via inhalation, ingestion (of liquid droplets in the air), and direct skin contact. Some of the health effects will be long-term sequelae and may last a lifetime or affect future generations. Crude oil is a known teratogen and can cause birth defects and changes in fetal development. The target organs for crude oil are the hematopoietic (blood forming) system, lymphatic system, nervous system, and reproductive system. The Benzene component is a known carcinogen.

    Persistent neuropsychiatric impairment following head injury is a significant public health problem. From 400,000 to 500,000 are hospitalized in the United States every year from head injury; many more people are injured and do not require admission. Head injury is the third most likely cause of dementia, after infection and alcoholism, in people younger than 50 years.

    In 1911, Hammond and Sutton of Philadelphia performed the first human-to-human kidney transplant with transient success. Since then the techniques and indications have evolved. The first wholly successful human transplant took place on December 23, 1954, in Boston, Massachusetts. Surgeon Joseph Murray performed a kidney transplant between identical twin brothers. Although this and subsequent twin transplants did little to solve the problem of rejection, these procedures contributed to proving the value of the procedure and to the solution of many technical problems.

    Neonatal emergencies are not uncommon problems. They appear either at the time of birth, during the in-hospital post-birth period, or at home within several weeks of discharge. In all instances they present significant diagnostic and treatment challenges to the clinician, and must be taken seriously.

    Cardiovascular disease (CVD) is the leading cause of death in the United States, accounting for approximately 500,000 deaths each year. More women in the United States die of heart disease than of any other cause, and one form of heart disease, myocardial infarction, is responsible for the majority of these deaths. In every year since 1984 it has claimed the lives of more women than men.

    A large number of reports have been produced on HP and its pathogenetic potential. In fact, although peptic ulcer disease is the most studied disease related to HP infection, this bacterium is seemingly involved in the pathogenesis of several extragastric diseases, such as mucosa-associated lymphoid tissue lymphomas (MALTomas), coronaritis, gastroesophageal reflux disease, iron deficiency anemia, skin disease, and rheumatological conditions.

A motor vehicle collision where there is only minor damage to the vehicles may result in personal injury claims for substantial sums.

    It is a common error that an attorney retains the wrong type of expert to testify in a lawsuit. This error is particularly common when the expert is a medical specialist. It is widely believed that a medical doctor who specializes in a particular organ system is qualified to formulate opinions and testify as to all issues concerning that organ system.
