**IMMUNOLOGY**

The immune system protects the body from disease. It plays a role in
infections, allergies and cancer. Some individuals are born with in
inadequate immune systems leaving them subject to a variety of
infections. Alternatively, as with AIDS, they may develop inadequate
immune systems. Occasionally, for reasons which are not understood, the
body's immune system attacks its own organs and causes autoimmune
disease.

There are numerous congenital immune disorders, but the most commonly
seen include the following:

**X-linked Agammaglobulinemia** -- a serious disease characterized by
recurrent, severe infections and requiring lifelong replacement therapy
and frequent antibiotic use.

**Common Variable Agammaglobulinemia** -- a heterogeneous disorder with
usual onset in the second or third decade. It pursues a milder course
and requires similar therapy. Bronchiectasis and intestinal disorders
may result.

**Selective IgA Deficiency** -- the mildest and most common
immunodeficiency. It may be asymptomatic or have recurrent respiratory
infections, allergy, diarrhea or autoimmune disease. Antibiotics are the
only treatment available.

**Underwriting Requirements**

An APS (VA Form 29-8158) is required.

  ---------------------------------------------------- ------------------
  Congenital Immune Deficiencies may be classified as  
  follows:                                             

  Mild -- asymptomatic or only occasional infections;  55-0
  complications responding promptly to treatment       

  Moderate -- several episodes per year with           175-125
  disabilities up to two weeks                         

  Severe -- multiple episodes with prolonged           R-225
  disabilities or chronic respiratory disease such as  
  bronchiectasis

**IMPAIRED GLUCOSE TOLERANCE**

Impaired glucose tolerance may be a precursor of diabetes. While it
exists, it is a risk factor for the development of arteriosclerosis.
Impaired glucose tolerance is diagnosed when the following three
criteria are present in a Glucose Tolerance Test (GTT):

1.  Fasting blood sugar less than 140 mg.

2.  Glucose level at 120 minutes between 140 mg. and 200 mg.

3.  A value greater than 200 mg. at 30, 60 or 90 minutes

If these three criteria are present on a recent (within 2 years) or
current GTT, enter the following table:

  ------------------------------------ ----------------------------------
  [Age]{.underline}                    [Debits]{.underline}

  0-14                                 R

  15-39                                100

  40-49                                75

  50+                                  50
  ------------------------------------ ----------------------------------

History or diagnosis of Impaired Glucose Tolerance based on GTT more
than two years old.

If subsequent blood sugar readings on a repeat GTT do not meet the
criteria above, no rating is required.

If no subsequent readings available, order GTT.

INDIGESTION

Indigestion or dyspepsia is the inability to digest, or difficulty in
digesting food. The underlying cause may be functional, systemic, or a
reflex effect from disturbance in other organs.

Acute indigestion, irritable bowel or acute gastritis, for example,
consisting of nausea, vomiting and pain of short duration, is usually
due to dietary indiscretion or poisoning. Chronic indigestion or chronic
dyspepsia is of more significance and usually the result of underlying
organic disease. Nervous indigestion, nervous stomach, heartburn or
gastric neurosis are terms applied to digestive symptoms associated with
emotional symptoms or nervousness. Acid indigestion, acid or sour
stomach, and hyperacidity describe indigestion characterized chiefly by
sour eructations (belching).

Repeated or prolonged attacks of indigestion are often due to ulcer,
spastic or mucous colitis, gallbladder, or other serious organic
disease, including heart disease, particularly at the older ages. If due
to organic disease, selection is based on the underlying cause.

**Underwriting Requirements**

When attacks are prolonged and/or chronic, an APS (VA Form 29-8158) is
required.

  ------------------------------------------------------ ----------------
  Mild or moderate -- infrequent brief episodes not      0
  requiring medical attention or prescription medication 

  Severe -- more frequent or prolonged, requiring        30
  medical attention, prescription medication and         
  requiring diagnostic tests                             
  ------------------------------------------------------ ----------------

INFANTILE PARALYSIS

Infantile paralysis, or poliomyelitis, is an acute infectious disease,
which affects the central nervous system and sometimes results in
paralysis of the movable muscles. Paralysis usually results within 1
week of an attack. Flu and poliomyelitis are often mistaken for each
other. Less than 50 percent of the attacks result in paralysis.
Longevity is not affected except where the respiratory muscles become
involved; therefore, it is important to evaluate the residuals
correctly.

**Underwriting Requirements**

An APS (VA Form 29-8158) is required if not adequately described.

INFECTIOUS MONONUCLEOSIS

Infectious mononucleosis, or glandular fever, is an acute mildly
contagious disease characterized by moderate fever, sore throat,
headache, and a feeling of exhaustion, which may be noted for many
weeks. Prolonged cases maybe confused with Hodgkin\'s disease,
tuberculosis, or leukemia.

**Underwriting Requirements**

This is a disease seen principally in young persons and recovery is
usually complete. In older ages, an incidence of the disease is looked
upon with suspicion. Ages up to 35, APS (VA Form 29-8158) in 6 months.
Over age 35, within 2 years an APS (VA Form 29-8158) is required.

  -------------------------------------------- --------------------------
  After recovery, no complications             0

  -------------------------------------------- --------------------------

**INFLAMMATORY BOWEL DISEASE**

**Crohn's Disease, Granulomatous Colitis, Ileitis, Regional Enteritis**
-- These are various names for chronic processes affecting the terminal
portion of the ileum but also occurring in other areas of the intestines
or stomach. The most common symptoms are chronic diarrhea associated
with abdominal pain, fever, anorexia and weight loss. Frequent
complications are intestinal obstruction and the formation of abdominal
fistulas and abscesses.

**Lower G.I. bleeding** -- Passage of blood by rectum may be occult
(detectable only by chemical tests) or overt (visible as blood). Blood
passed by rectum may originate at any point from the mouth or nasal
passage of the anus. If the blood appears blackish (melena) it suggests
an upper G.I. source, whereas if it is brighter, a lower source of
bleeding is probable. Regardless, any bleeding requires identification
of the source and treatment and follow up as appropriate. While
hemorrhoids are a common cause of bleeding, other conditions such as
polyps, diverticulosis, inflammatory bowel disease, cancer, ulcers and
esophageal varices must be ruled out.

**Megacolon (Hirschsprung's Disease)** -- Megacolon is a congenital
dilation of the large intestine. Symptoms may include constipation,
severe colic and malnutrition. Surgical intervention may be required.

**Mucous Colitis, Irritable Bowel, Spastic Colon** -- These are motility
disorders of the small and large intestine with abdominal pain, diarrhea
and constipation. They are generally associated with stress.

**Ulcerative Colitis** -- Ulcerative colitis is a chronic, recurrent
disease of the colon with diffuse inflammation, ulceration, crypts, and
crypt abscesses. Symptoms include rectal bleeding, abdominal pain,
diarrhea, weight loss and fever. There is increased risk of cancer of
the colon and rectum. Treatment may require surgery.

**Ulcerative Proctitis** -- This is a more benign and limited form of
colitis that usually remains localized to the rectum, although about 10%
undergo more extensive spread.

**Anal Fissure** -- An anal fissure is a split in the mucous membrane
that covers the anal sphincter.

**Fistula-in-Ano** -- A fistula is a deep ulcer, or abnormal tract often
leading from the surface to an internal hollow organ. A fistula near the
anus is known as fistula-in-ano. Fistulas occur more frequently in
persons afflicted with chronic colitis, ileitis and tropical
dysenteries. Recurrences are common.

**Hemorrhoids, Piles** -- Hemorrhoids are caused by congestion of veins
in the rectal area. They may be internal or external with reference to
the rectal sphincter muscle.

## INFLUENZA-VIRUS INFECTION

Influenza, flu, grippe, or grip is an infectious disease characterized
by sudden onset, fever, marked prostration, muscular and joint pain, and
inflammation of the respiratory passages. Pneumonia is the most frequent
complication.

INSOMNIA

Wakefulness or inability to sleep during the period when sleep should
normally occur is known as insomnia. Temporary emotional upsets,
external stimuli, such as noises or lights, and the use of tea or coffee
before retiring are frequent causes. Insomnia is more significant if
related to nervous influences, the frequent use of mild sedatives or
hypnotics, or to the use of narcotics.

**INTERSTITIAL LUNG DISEASE (ILD)**

This is a group of conditions that all cause a similar change in the
lung -- inflammation that resolves with fibrosis. As a result there is
reduced efficiency of oxygen exchange between the air and blood. Each of
the diseases is uncommon, but, as a group, they will be encountered
regularly.

ILD may be grouped by causes as follows:

**Diseases of Unknown Cause** -- Idiopathic pulmonary fibrosis,
sarcoidosis, vasculitis, collagen vascular diseases and others.

**Infectious Diseases** -- Viral, bacterial and fungal infections
occasionally resulting in generalized interstitial fibrosis.

**Inhaled Dusts and Gases** -- Silicosis, coal miner's lung, asbestosis,
chlorine gas and others.

**Drugs** -- antibiotics, Dilantin, anti-depressants, gold, oral
hypoglycemic agents and many others.

The factors to be considered include current lung function and the
potential for progression of the lung disease. Since ILD is a
restrictive rather than obstructive lung disease, the FEV1 may be normal
even with advanced disease. The vital capacity and the diffusing
capacity are often reduced; the Single Breath Diffusing Capacity (DLCO)
is the more useful indicator of the severity. The primary value of the
chest x-ray is in assessing the extent of the pulmonary fibrosis.

Each specific cause of ILD must be assessed for its potential to
progressively destroy the lungs. Most occupational, drug and infectious
causes will become stable several years after the person has been
removed from the exposure, and some may resolve completely after time.
However, many of the cases associated with diseases of unknown cause
carry the risk of inexorable decline to lung failure and the rate of
decline is often difficult to predict.

INTERVERTEBRAL DISK RUPTURE

(Herniated Nucleus Pulposus)

An intervertebral disk or disc is a layer of fibrous cartilage between
the segments of the spine. It consists of a fibrous ring enclosing a
pulpy center (nucleus pulposus). A rupture and displacement of an
intervertebral disk usually results in pressure on the spinal cord
and/or spinal nerve roots, generally producing pain and sometimes
paralysis of the affected nerves.

Rupture of a disk in the lower part of the spine (thoracic or lumbar
region) may produce low back pain and pain along the nerve trunks of the
legs, or even paralysis of those nerves. Because of the function and
nature of the structure of the upper part of the spine (cervical
region), a ruptured disk in this area is of greater significance.
Treatment is usually surgical removal of the affected disk through an
opening made by the removal of a portion of the vertebra (laminectomy).
A spinal fusion or bone graft may be required to close the operative
opening.

An APS (VA Form 29-8158) may be required if not adequately described.

INTESTINAL OBSTRUCTION

Among the most common causes of intestinal obstruction are strictures,
adhesions and hernias. Less common causes are tumors or other masses,
intusseseption (telescoping), volvulus (twisting), or paralytic ileus
(decreased activity).

**INTESTINAL PARASITES**

Infestation of the human intestinal tract by a group of parasitic worms
occasions certain symptoms referable to the intestinal tract itself, and
in some instances with manifestations of involvement of other organs.
There is usually marked weakness, often a severe anemia.

The most common type of manifestations are:

1.  Ancylostomiasis, uncinariasis, or hook worm

2.  Ascariasis, or round worm

3.  Cestodiasis, or tapeworm -- beef -- fish

4.  Oxyuris Vermicularis, or pin worm

5.  Trichinosis, or pork worm
