Infectious Disease

By: AMFS Medical Experts Nationwide

Infectious diseases are among the most common conditions for which patients seek medical care, and potentially the most serious. Fortunately, since the discovery of penicillin over 70 years ago, antibiotics have made the treatment of serious infections highly successful. Nevertheless, physicians and advanced practioners such as nurse practitioners and physician's assistants must use caution in administering antimicrobial medications, both to ensure effectiveness and to prevent side effects. Careful prescribing will help minimize the legal risks resulting from antibiotic treatment.

Hospital Medicines and Transitions of Care

By: AMFS Medical Experts Nationwide

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

By: AMFS Medical Experts Nationwide

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.

Transient Disorders of Awareness

By: AMFS Medical Experts Nationwide - R. Starkey

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.

Carpal Tunnel And Other Tunnel, Tendon And Inflammatory Syndromes

By: AMFS Medical Experts Nationwide - John Toton

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.

Kidney Transplantation in Medical Malpractice or Personal Injury Lawsuits

By: AMFS Medical Experts Nationwide

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.
