Liver Pathology Expert Witness

Liver pathology is a medical specialty in which physicians study the diseases of the liver. They do this in order to discover all of the signs and symptoms so that they can appropriately, safely, and effectively treat and diagnose the diseases.

Lupus Expert Witness

Lupus is a chronic autoimmune disease. It can affect any area of the body, and is much more common in women than men. It is mostly treated with palliative medications, because there is no complete cure.

Lung Cancer Expert Witness

Lung cancer is a deadly condition in which cancerous cells affect the function of the patient’s lungs. It can result in shortness of breath and coughing. The most common course of treatment is chemotherapy.

Lung cancer: does the patient have cancer or is that scar tissue in the lung from tuberculosis or something else? The doctor has a duty to obtain any previous chest x-rays. If this is a “new lump” seen in the lung and the patient had a chest x-ray a year before and five years ago, which showed the same lump, it couldn’t be cancer because it hasn’t changed. How was the patient evaluated before surgery? Bronchoscopy, looking into the windpipe, and obtaining sputum specimens for germs and cancer analysis is important. The condition must be properly diagnosed, biopsies performed when possible, the patient told about the risks, and the previous chest x-rays checked. Very often we see negligence in failing to examine earlier x-rays, whether they were taken for tuberculosis screening, for work physicals, for insurance, for previous hospitalizations, or for any other condition. Have good copies made of all x-rays. Was the lump seen earlier? Was it misdiagnosed when the cancer cure rate would have been higher? Has it changed? Is it cancer or was it some old scarring, tuberculosis or pleurisy? Lung cancer is one of the top five diseases in terms of malpractice dollar awards. The typical case alleges misdiagnosis via poor diagnostic methods or mismanagement of diagnostic tests. Delayed diagnosis of lung cancer offers a much poorer prognosis, and therefore any malpractice award is typically large in terms of dollar value.

Low Back Pain Expert Witness

Low back pain is often caused by repetitive motions, strenuous activities, or improper posture. Patients with this condition should visit a chiropractor, general practitioner, or surgeon. Treatment techniques include acupuncture, back adjustments, medications, surgery, or lifestyle changes

Long Term Care Expert Witness

Long term care physicians are responsible for making plans of treatment for elderly patients. They want to be sure that the patient will live in comfort and safety, so they help with everyday activities as well as administer medicine and food.

Liver Pathologist Expert Witness

Liver pathology is a medical specialty in which physicians study the diseases of the liver. They do this in order to discover all of the signs and symptoms so that they can appropriately, safely, and effectively treat and diagnose the diseases.

Liver Disease Expert Witness

Liver disease is the term for a group of diseases affecting the human liver. Most liver diseases are associated with jaundice (yellowing of the skin caused by an increased level of bilrubin) because the liver is not functioning to remove the excess bilrubin.

Because most medications are metabolized in the liver, Drug Induced Liver Injury (DILI) is frequently the main toxicity of many drugs on the market. Medications can induce DILI either by predictable mechanisms (i.e., acetaminophen) or their toxicity is unpredictable (idiosyncratic DILI). Acetaminophen (Tylenol and similar products) is the main cause of Acute Liver Failure (ALF) in the USA.

The reasons for poor outcomes, such as death or liver transplantation, in acetaminophen ALF are: i] delays in initiating treatment with Mucomyst; ii] incorrect use Mucomyst in either dosage or duration of treatment; iii] use of sedatives and /or narcotics when patients with ALF experience irritability, anxiety, pain or insomnia, which often accelerates the development of coma in ALF; and iv] delays in transferring the patient for Liver Transplantation. Physicians and RNs in Hospitals not familiar with the diagnosis and treatment of acetaminophen ALF or other causes of ALF may be responsible for the progression of the disease. A rapid diagnosis of ALF allows implementation of appropriate management. The liability of the Pharmaceutical Companies is often limited to the inadequate labeling and warning box; this may change since the FDA has considered ‘forcing’ correction of labeling deficiencies.

Medications that induce idiosyncratic DILI are many and the patient’s susceptibility cannot be anticipated. The Hospital liability is similar to that of acetaminophen-induced DILI if the patient presents with ALF. The Pharmaceutical Companies are often found to be liable if the pre-clinical research or the pre-marketing clinical studies shows evidences of a ‘signal’ liver injury that is similar to that observed in the cohort afflicted with the DILI (and ALF). The main issues are related to interpretation of that data including: i] cell toxicity in culture systems and the specificity and relatedness to the human DILI; ii] pharmacokinetics and liver toxicity in animals; iii] evidences of liver injury in clinical studies – even at a relatively low level- ; and iv] evidences of drug-drug or drug-disease interactions that could or should have been inferred.

Although valuable to the medical and scientific community, neither the Med-Watch Reports to the FDA nor the published case reports provide statistical support for the causal association between a medication and ALF. In addition, and except in rare instances (e.g., rechallenge), presumed idiosyncratic DILI cannot be attributed unequivocally to any drug. As evidence of the diagnostic uncertainties, in the United States, the cases of acute liver failure of undetermined causes (17%) exceed those attributed as probable to all medications combined (13%), excluding acetaminophen.

Acetaminophen- induced ALF is not associated with chronic liver injury; patients that survive recover completely. In contrast, it has been postulated that liver fibrosis and cancer may result from the liver toxicity in some cases of idiosyncratic DILI. These presumed chronic complications would constitute an extraordinary medical burden to patients treated with that medication. Because these alleged long-term complications of some DILI have significant medical, social, legal, and financial repercussions, is necessary to evaluate the scientific merits of the proposed mechanisms.

Liposuction Expert Witness

Liposuction is a type of cosmetic procedure that focuses on removing undesired areas of fat on the patient’s body. The surgeon must remove exactly the right amount of fat. Too little, and the patient may not be satisfied; too much, and the skin will not stretch tightly over the area, resulting in dimples and dents. Liposuction can be performed on many places of the body, especially the butt, thighs, and stomach.

Lifespan Assessment Expert Witness

A lifespan assessment professional is responsible for assessing many factors of a patient’s life in order to determine how they can remain healthy for the longest amount of time possible.

Life Expectancy & Mortality Expert Witness

Life expectancy and mortality professionals study the typical human life expectancies as the human population continues to evolve. They do this because they want to study the effects of certain diseases on the population, as well as be able to predict how long patients should live.
