Mucormycosis (zygomycosis) is a serious, potentially deadly fungal
infection that's infrequently diagnosed.
Many different fungi may cause mucormycosis;
infections with the Mucoraceae family of fungi predominate as causes; hence many
investigators use the term mucormycosis instead of zygomycosis.
Risk factors
include poorly controlled debilitating diseases, immunosuppression and trauma
(usually serious injuries), and groups of such patients injured in natural
disasters.
Symptoms and signs first appear usually in the body area infected
and may occur as follows: fever, headache, reddish and swollen skin over nose
and sinuses, dark scabbing in nose by eye(s), visual problems, eye(s) swelling,
facial pain, coughing sometimes with bloody or dark fluid production,
shortness of
breath, diffuse abdominal pain,
bloody and sometimes dark vomitus, abdominal
distension, fever, flank pain, an ulcer with a dark center and sharply defined
edges, headaches, and mental-status changes may occur.
Preliminary diagnosis is
made by patient history, physical exam, and the patient's risk factors for
mucormycosis; definitive diagnosis is made by identification of fungi in the patient's tissue.
Almost all patients require surgical debridement of infected
tissue, antifungal drugs (mainly amphotericin B), and good control (treatment) of
underlying medical problems such as diabetes.
Complications of mucormycosis can
be dire: blindness, organ dysfunction, loss of body tissue due to infection and
debridement, and death.
The prognosis (outcomes) of mucormycosis infections range
from fair to poor; there is about a 50% death rate that rises to about 85% for
rhinocerebral and GI infections.
Prevention of mucormycosis centers on avoidance
of risk factors (see above), but not all infections are likely to be prevented;
there is no vaccine for mucormycosis.
Research shows mucormycosis infection incidences are increasing, especially with immunosuppressed individuals; more
research may occur as the number of infections increase.
Diabetes mellitus is a chronic condition characterized by high levels of sugar (glucose) in the blood. The two types of diabetes are referred to as type 1 (insulin dependent) and type 2 (non-insulin dependent). Symptoms of diabetes include increased urine output, thirst, hunger, and fatigue. Treatment of diabetes depends on the type.
Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.). Fever is part of the body's own disease-fighting arsenal: rising body temperatures apparently are capable of killing off many disease- producing organisms.
Abdominal pain is pain in the belly and can be acute or chronic. Causes include inflammation, distention of an organ, and loss of the blood supply to an organ. Abdominal pain can reflect a major problem with one of the organs in the abdomen such as the appendix, gallbladder, large and small intestine, pancreas, liver, colon, duodenum, and spleen.
Chronic cough is a cough that does not go away and is generally a symptom of another disorder such as asthma, allergic rhinitis, sinus infection, cigarette smoking, GERD, postnasal drip, bronchitis, pneumonia, medications, and less frequently tumors or other lung disease. Treatment of chronic cough is dependant upon the cause.
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
Blindness is the state of being sightless. Causes of blindness include macular degeneration, stroke, cataract, glaucoma, infection and trauma. Symptoms and signs may include eye pain, eye discharge, or the cornea or pupil turning white. Treatment of blindness depends upon the cause of the blindness.
Blindness is defined as the state of being sightless. A blind individual is
unable to see. In a strict sense the word blindness denotes the condition of
total blackness of vision with the inability of a person to distinguish darkness
from bright light in either eye. The terms blind and blindness have been
modified in our society to include a wide range of visual impairment. Blindness
is frequently used today to describe severe visual decline in one or both eyes
with maintenance of some residual vision.
Vision impairment, or low vision, means that even with eyeglasses, contact
lenses, medicine or surgery, you don't see well. Vision impairment can range
from mild to severe. Worldwide, between 300 million and 400 million people are
visually impaired due to various causes. Of this group, approximately 50 million
people are totally blind. Approximately 80% of blindness occurs in people over 50 years old
