The Common Vein

Disease is a state of disorder that has a variety of causes including for example infection, malignancy, trauma, or circulatory disorders resulting in structural and or functional impairment manifesting in a clinical presentation of symptoms or signs.  Other diagnostic tools include laboratory investigation and imaging techniques, and treatment is most commonly via medical therapy or surgical therapy.

Malignant Disease in the Liver The series of normal and pathological images are grouped at the cellular level, (top images) at the tissue level (middle) and the organ level (below).  The normal images are on the left and the abnormal are on the right.

In the first row the normal liver cells have a normal size ratio of nucleus to cytoplasm .  The cells on the right represent malignant disease, and the nuclear cytoplasmic ratio is increased, a feature characteristic of malignant neoplasia.  In the second row,  the normal histology is demonstrated on the left and a cluster of blue malignant cells is shown as seedling tumor surrounded by normal liver on the right.  In the last row the normal liver as an organ is noted to your left and the seedling of malignancies have grown to enormous proportions invading the space of the normal liver and choking and destroying the normal tissue.  In the CT reconstruction of the abdomen ascites has caused the abdomen to swell

 

There is a bridge that needs to be explored between biology, (as the medical and scientific world sees it) and its “ripple up” or “ripple down” effect on the person, family, community and nation (as the young student of biology knows or has experienced it).  The key to the bridge is the understanding of universal and fundamental principles such that events at the molecular and microscopic level can be translated and understood in the macroscopic world of common experience.

Biological Units and Non Biological Units

Bricks and mortar behave differently from cells and interstitium. However it useful to think and work with the concept of units in mind and to continually compare and think about them in parallel since it helps understanding.  For example if the cement is abnormal between the bricks then there is a lack of cohesiveness and a subsequent weakening of the wall as a whole which presents as a danger .  Similarly if the interstitium of a tissue is abnormal, such as occurs in the aberrance of collagen in Ehlos-Danlos disease or Marfan’s syndrome then the whole body is weakened.  In the course of this work we will often use the word “biological units” to describe a discrete biological entity with the understanding that each unit is still a part of a whole.  In giving the cell, tissue, organ, body, family, community, nation and people of the world a common unit of “biological entity” we create an understanding of the responsibility of each to the other, and the consequences of health and order in each, and the negative consequences of disease and disorder in each on the whole.  It helps us to put ourselves and our mission in a global perspective

Time and  Disease

Just as our understanding of physiologic processes is informed by assessing them in the context of time, so is the passage of minutes, hours, and days critical to understanding diseases and their progression within the body.  Indeed, one of a physician’s primary responsibilities, diagnosing illness, is accomplished by assessing symptoms as they have occurred within a particular timeframe and subsequently classifying the illness as mild and in its early stages, advanced and potentially life-threatening, or somewhere in-between. For instance, the character and size of a malignant tumor, is important for classifying the progression of the cancer that caused it.  A small, immature tumor may indicate an early, treatable stage of disease while a large, tumor that has had time to metastasize presents as a more serious, life-threatening stage of cancer. This serves as just one example of the central role a working knowledge of time and disease may play .

Before delving into examples of disease processes it is important to realize that every physiologic system (Circulatory, Respiratory, Digestive, to name a few) is characterized by its ability to execute events both instantaneously and over longer periods of time. The immune system, for instance, is capable of very quickly initiating inflammatory responses through the rapid release of histamine from mast cells, leading when aberrant to anaphylaxis in serious cases.  This occurs within a few seconds of the initiating event.  On the other hand, this same system’s primary response to a bacterial or viral infection relies largely on the steady mounting of antibodies against the invading pathogen over a period of days. Similarly, diseases and disorders that afflict our physiologic systems may occur within seconds or across days and years. For instance, some disorders of the circulatory system, such as heart attacks due to acute coronary thrombosis, may afflict their victims within seconds while others, such as atherosclerosis, develop over years. Thus, it becomes apparent that one must must establish a working knowledge of disease as it relates to time in order to effectively diagnose and treat patients.

Disease Measured in Seconds, Minutes, Days, and Years

In the emergency setting, a variety of serious conditions can develop in a matter of minutes such that rapid response and treatment is absolutely essential to preserving the life of the afflicted patient.  Anaphylaxis, acute coronary thrombosis, and pulmonary embolism can all act within seconds to compromise essential physiologic functions, sometimes so severely that death becomes imminent without immediate treatment. Indeed, the rupture of an aneurysm or the blockage of a blood vessel or airway for even a short period of time can cause catastrophic and sometimes irreparable damage to the body.  Loss of consciousness can result from anoxia in about thirty seconds and brain damage results not too long after this. Still other diseases, such as influenza and bacterial infections, do not become fully manifest until days after initial exposure to the pathogen, and HIV, one of the most virulent viruses on the planet, may remain latent within the body for up to ten years. Thus, understanding the time frame within which symptoms of particular diseases typically appear is both daunting and critical to accurately diagnosing the signs of illness patients present within clinical settings.

 

Time and Diagnosis

The diagnostic process is a three part process.  Acquisition of data, processing the data, and then interpretation of the data.  This is true whether it relates to the clinical environment, lab tests, or imaging tests.   A clinical evaluation may take 30-45 minutes, and sometimes it is all that is necessary to come to a diagnosis.  An example of this may be a disease such as asthma.  On other occasions the diagnosis is made once routine tests such as routine blood tests, EKG and or chest X-ray are added.  Pneumonia is such an example when a consolidation is found on a chest X-ray.  The acquisition of the data  for a chest X-ray is short (measured in seconds) processing time (perhaps 30 seconds).  The data is sent to a work station where it waits in line to be read by the radiologist.  Once it reaches the front of the line, interpreation takes a few minutes.  Communication time can range from an immediate phone call, fax, or electronic report (minutes) to typed report correction and fax (about 24 hours)

If after the clinical presentation and routine studies the diagnosis still eludes the physician, then special directed diagnostic studies are required.  A patient who presents with fever and a neck mass will require a CT scan.  This study takes about 10 seconds to acquire the data, about 30 seconds to process the data.  The processed data is then placed onto a work list for interpretation by the radiologist and is interpreted within 1 or 2 hours.  If for example multiple enlarged nodes are seen a variety of diseases can be suspected and a differential diagnostic list is created but a biopsy is required for further workup.  This of course will occur on another day and another time and the biopsy will be performed by a surgeon or a radiologist using imaging guidance.  The material is submitted to a pathologist who has to process the material, and examine the material under a microscope, and render an interpretation.  This usually takes about 24 hours but even at this level further staining to delve deeper into the diagnosis may be required.

The goal is to make an accurate diagnosis as soon as possible.  The next goal is to initiate treatment as soon as possible.  A patient who has chest pain and is diagnosed with acute myocardial infarction in a timely fashion, should be referred to the cardiac catheterization laboratory for consideration for thrombolysis.  If the findings suggest thrombus in the coronary artery, then treatment with thrombolysis can be initiated immediately.  The time between diagnosis and treatment is minutes.

Another aspect of time and diagnosis is the determination of the acuity of a disease process using imaging.  If a patient presents with a focal neurological deficit and the question of an acute stroke is raised.  MRI with diffusion weighted imaging can differentiate between an acute process or a chronic process.  Timing of the disease has significant implications in the treatment that may be employed.  An example of the difference between an acute and chronic infarction in the brain is shown below

 

Acute Infarction – Loss of Brownian Motion

Chronic Infarction Changes in Volume The CT scan on the left was taken after the patient presented with acute focal deficit.  It  suggests bilateral subtle abnormalities in the occipital lobes.  The MRI shows that the findings on the right side in the diffusion weighted sequence (right image) with intense brightness is diagnostic of an acute process, while the finding in the left occipital lobe are unrevealing suggesting that they are of a chronic nature.

Time in Treatment

It is important to realize, that treatment of diseases also occurs over a specific time frame and requires knowledge of how certain drugs and therapies function over time.  A patient in ventricular fibrillation can be converted by an automated external defibrillator in seconds, and a patient who has anaphylaxis can recover within a minute after receiving epinephrine, either subcutaneously or intravenously.  Medications given intravenously will become effective quicker than those given orally.  However an antibiotic given intravenously will only be effective when a critical balance is overcome that enables the body to dominate the infection.  This may be hours in coming.  Other drugs such as sedatives and anxiolytics only require the time to reach their target organs in order to take effect.  This is usually about 30 seconds.  Oral medications have to be absorbed into the circulation for systemic effects.  Some medications are absorbed by the stomach and the time to become effective is less than those that are absorbed in the small bowel.

Other aspects of time to be considered relate to how long the drug is effective.  In pharmacology terms the half-life of the drug reflects the duration which a drug may be active, since half life is defined as the time that is required for half of the drug to be removed either by physical or chemical means.  Some drugs like epinephrine are short lasting (minutes) others last for hours (insulin), while others are effective for days (coumadin and digoxin).  Subcutaneous depot medroxyprogesterone acetate which is a subcutaneously injected contraceptive for females is injected every 3-4 months.

Narcotics and steroids, for instance, are often prescribed for a limited amount of time, as prolonged use of either one may result in addiction or other undesirable physical effects, respectively. Other treatments, such as birth control pills to manage an endocrine disorder or medication to combat autoimmune disease, are necessarily taken for prolonged periods of time. Chemotherapy, depicted in the image below, is of the latter category, as it is often completed over many months to rid the body of malignant cells.

So, as has been illustrated here, what makes time so fundamental to human physiology and disease is that it defines a broad spectrum of bodily process, whether life-giving, life-maintaining, or life-ending. The effective practice of medicine, then, relies upon a mastery of these concepts and a continual appreciation for the centrality of time in determining the health outcomes of one’s patients.

 

States  of Being – the Extremes and Somewhere In between

The section on states of being is intended to provide understanding of health and disease in the context of “opposites” in the sciences and arts.  In the world of physics, chemistry, and mathematics, units that are equal and opposite are “relatively” absolute.  Thus for example negative and positive are the extreme opposites.  In the world of art, literature, dance, biology,  and medicine, opposites are relative.

 

Positive and Negative 84154b04.698 positive and negative extreme states black and white Davidoff art Davidoff MD

 

The positive of the proton and the negative of the electron create no intellectual challenge at the superficial level – opposite and equal charges or forces.  Scientists involved with these forces probe their relative energies but as “lay” professionals we accept the extreme and apparent absolute difference between the two forces.  Despite the extremes of their nature they provide an attraction for one another.  The 0 and 1 of mathematics describe the nothing and the something, and they are the building blocks of mathematics and also form the basis of our computer language.

In the visual world of gray scale, we get black and white at the two extremes and in the world of the alphabet we get the a and the z at opposite ends.

In the cardiovascular system the relatively positive pressure in the left sided systemic circulation created by the left ventricle, enables flow throught the capillary circulation, perfusion of the cells tissues and organs, and subsequent return of the blood to the relatively low pressure of the right side of the heart.  The pulmonary circulation on the other hand is serviced by the pumping action of the right ventricle, which creates a positive force and flow to the capillaries of the lung and subsequent return to the low pressure of the left atrium.

The states of health and disease,  which can also be viewed as relatively positive and relatively negative can be reversed with appropriate resources and adaptation.  The healers of the world, sometimes the government, sometimes the people, sometimes the police force and sometimes the doctors, sometimes the street sweepers, and sometimes the lawyers and often the teachers – in fact the function of most of us – our function is to to try and change the world from a state of relative disorder to a world of relative order.

In the following images we will provide examples of the extreme positive and extreme negative in human biology to exempflify the states of health and disease, and order and disorder, starting at the level of a country and continuing to the cellular level.

 While it is obvious to the unprofessional eye that a difference exists between the extreme examples of health and disease – there are grades of severity and grades of the extreme that require the professional eye to recognise and attempt to correct , in order to realign the community, person, organ or cell and even parts of the cell on an orderly path.

1775 – A Nation in Disorder – A Dissatisfied People

The American revolution was born out of a country in despair where the dominant state was one of a negative sentiment of the people and the need for freedom to create  nation of independant destiny.  Even after the first shots of the revolution were fired at North Bridge in Concord, the lives of the Bostonians were described by Abigail Adams to John Adams in despicable terms.

A Negative Sentiment

The sentence above is one that describes the ambience of extreme despair and negativity of the community and if it was a true reflection of the ambient sentiment it is no wonder that the revolution was born out of such a spirit.

This simple chart of the order and disorder exemplifies the desirables and the undesirables of life – Ironically it was posted by the Bostonians in the hope of influencing the besieged British to forego their misery and seek a better life on the outside.

For the United States, the state change from relative disorder to relative order  has lasted 231 years but in the grand scheme of things is a relatively short time.  Ancient communities have been through cycles of disorder and order on innumerable occasions and are here to tell their tales.  Others have disappeared.  Modern day revolutions and dramatic changes are being told in Russia, South Africa, China, Iraq, Ireland, and the Middle East .  Our mission as the human race is in general, one of trying to find the order for ourselves and our nation, and hopefully to other nations, with world peace as a larger goal.

It does not take much to drag a state of relative order to a state of chaos and disaster. In our recent past, Hitler was the fire that ignited a hell, while Stalin who helped put one hell to rest, started another. Religious despots who see the world without a broader view of a global order (Khomeini, bin Laden)  As my daughter Dani (10 years) told me – “If you want peace in the world you need to have peace in each home.”
