Celiac disease (or coeliac disease) is a genetically predisposed autoimmune disease which affects the small intestine. This disease is determined gliadin, a protein found in wheat, barley and rye. The immune system cross-reacts with the intestinal tissue, after the tissue transglutaminase modifies the gliadin, and so, an inflammatory is triggered.This process leads to damage of the villi found on the intestinal mucous membrane, damage known as villous atrophy. This disturbs the absorbtion of nutrients. Inspite of the fact that this disease is the result of the action of a wheat protein, this disease should not be mistaken with the wheat allergy.


The signs and symptoms of the disease are determined by the intestinal damage and by the consequences of the malabsorbtion. The most usual symptoms of celiac disease are: diarrhea, vomiting, weight loss, fatigue, and abdominal distension, but even though this disease is primarily an intestinal disorder, bowel symptoms may be subtle or absent. In some cases the diagnosis may be rather based on symptoms determined by the malabsorbtion . For example in subtle disease, the adults may only complain of fatigue and their blood tests show a mild anemia and the children may have psychologiacal problems and malabsorbtion-related disturbances.

T he diarrhea is a very characteristic sign of celiac disease  and it usually manifests as the presence of voluminous, discolored and malodorous stools. The cramping, bloatedness accompanied by abdominal distension (determined by the gas resulted from fermentation processes) abdominal pain and lesions on the mucous membrane lining the inner side of the cheeck are other common features of celiac disease. As the disease progresses and the intestine is more affected, lactose intolerance may occur. The gastrointestinal symptoms may be various and some patients may have a normal intestinal tranzit or even display a tendency towards constipation.

Celiac disease may lead to other intestinal disorders such as stricturing or ulcerative jejunitis or it may increase th risk of developing adenocarcinoma and lymphoma.

As a consequence of the impaired intestinal absorbtion other disturbances may also occur determined by the deficit in vitamins, calcium, and nutrients. Weight loss may occur in adults due to the insufficient amount of aminoacids, glucose and fats absorbed and in children stunted growth and pubertal delay are determined by this form of malnutrition. The malabsorbtion of calcium may lead to osteopenia, osteomalacia and osteoporosis, affecting the bone metabolism and increasing the risk of fractures. Anemia may be determined by more than one cause, all related to the impaired absorbtion function: by the malabsorbtion of iron there will occur iron deficiency anemia and the malabsorbtion of vitamin B12 and folic acid will lead to megaloblastic anemia.

At the moment the only effective treatment consists in a gluten-free diet. Nevertheless there are people with refractory disease whose condition does not improve after taking the dietary measures. In these cases the treatment with corticosteroids should be considered.

Down's syndrome is a chromosomial disorder caused by the existence of an extra 21 chromosome. Down's syndrome affects the cognitive abilities and development, facial appearance and physical growth.

The symptoms of Down's syndrome are usually noticed at birth but the syndrome may be identified during pregnancy by a medical procedure named amniocentesis.

The most common facial features of Down syndrome are: a flat face, a flat nasal bridge, small nose, the specific upward slant to the eyes, epicantus (the presence of a skin fold in the medial corner of the eye), small ears that usually fold at the top, abnormally small mouth (microstomia) and chin (microgenia),  Brush field spots (white spots in the iris) large protuding tongue and microcephaly (abnormally small head).

The babies with this disorder are usually born earlier than normally, they  have smaller feet and hands, their articular ligaments are loose and they have a reduced muscular tone (hypotonia). Hypotonia a main feature in Down's syndrome. The muscles of the patient feel floppy and it usually affects all the skeletal muscles in the body. Therapy for hypotonia should be started rapidly, in order to reduce the disease's impact on the development of motor skills.


An early intervention is also the key in preventing the impact of the low muscular tone on the future speaking and eating skills of the baby. Microstomia (the small mouth), accompanied by the undeveloped sinuses and the frequent respiratory infections the individuals with Down's syndrome are exposed to may lead to respiratory problems, thus leading to the baby's necessity to breathe through mouth and so, as consequence there will be encouraged the protuding tongue. This symptom, combined with hypotonia will lead to nurshing problems, since the child will not be able to eat properly and later on, there will occur problems with eating solid food.

Other features of Down's syndrome are: the Simian crease (unique palmar crease- in babies without the disease there are two palmar creases on each hand), short limbs, the lack of the distal phalanx in the little finger,flat, broad hands with short fingers, weaker or absent Monro reflexes, broad flat feet with short toes and with an abnormally large space between the big toe and the second.

The individuals with this disorder usually have a lower than average IQ and cognitive abilities. They usually have a speech delay not only because of the intellectual impairment but also determined by hearing loss, malformations of the acustic conduct or middle ear problems.

Vision problems will also occur in more than 70% of children with this syndrome. The ophtalmological problems may range from myopia and hypermetropia to blocked tear duct cataracts and astigmatism.

The congenital heart defects that occur with this disorder are atrioventricular septal defect, ventricular septal defect and atrial septal defect, requiring surgery. Endocrine problems may also occur, the most frequent are represented by thyroid disorders (hypothyroidism and hyperthyroidism) but pituitary problems may occur as well thus leading to a shortage of growth hormone, which leads to an even more marked growth delay.

The gastrointestinal tract is frequently affected by many anatomical and functional abnormalities. Aganglionnic megacolon, duodenal atresia, anular pancreas, tracheo-esophageal fistula and malabsorbtion disorders are the most common gasrtointestinal problems.

Cardiovascular disorders represent the most prevalent serious diseases in industrialized countries and a growing problem in most developing countries. The signs and symptoms of cardiac disease are usually the result of myocardial ischemia, of the disturbances of the contraction or relaxation of the myocardium,  abnormal cardiac rhythm or by the obstruction to blood flow.

Ischemia, is determined by an imbalance between the heart's oxygen supply and demand. Ischemia usually manifests as chest discomfort and the reduction of the heart's pumping ability leads to fatigue and elevated intravascular pressure upstream the affected ventricle. The latter leads to an abnormal fluid accumulation, with peripheral edema, dyspnea and pulmonary congestion. Obstruction to blood flow (like, for example, the one that occurs in valvular stenosis) may determine symptoms similar to those of myocardial failure. Cardiac arrhythmias usually have a sudden onset and the signs and  symptoms of this disturbances are: palpitations, syncope, dyspnea and hypotension, which may  occur abruptly and may disappear as rapidly.

Even though chest discomfort, dyspnea, syncope and edema are the most common features of cardiac disease, they may occur in other conditions as well, making the differential diagnosis quite difficult. For example dyspnea is also observed in other disorders such as pulmonary disease, marked obesity, and anxiety . Similarly, the chest discomfort may be the result of many other non cardiac and cardiac causes, not only of myocardial ischemia. Edema, an important feature in most untreated or inadequately treated cases of heart failure, may also occur with primary renal disease, parasitoses, chronic liver disease and in hepatic cirrhosis. Syncope (brief loss of consciousness followed by rapid, spontaneous revival) occurs not only in the patients with serious cardiac arrhythmias but it's also an important symptom in many neurologic diseases.

The patient may complain of persistent fatigue because of the reduced cardiac output. The low cardiac output will lead to an increased respiratory rate, especially in case of pulmonary venous congestion. Central cyanosis is also determined by the insufficient oxigenation and when is associated  with clubbing of the fingers and toes it  indicates right -to- left cardiac shunting.  Cyanosis in the distal extremities accompanied by cool skin and sometimes increased sweating is usually the result of vasoconstriction in severe heart failure cases. Some disorder such as endocarditis or rheumatic fever may cause fever. Low grade fever is also common after a miocardic infarction.

The examination of the peripheral veins may also give important information. They should be observed for arteriovenous shunting, arteriovenous malformations and varicosities. The inflammation and the tenderness of these peripheral veins usually indicate thromboflebitis. Chest diformities may suggest congenital cardiac malformations or genetic disorders such as X monosomy (or Turner's syndrome) in which the chest has a bird-like, proeminent sternum (pectus carinatus). In some cases. an aortic aneurism determined by syphilis may be suggested by an upper chest bulge. Pectus excavatum ( a depressed aspect of the sternum) may indicate the  myxomatous degeneration of the cardiac valves or chordae or a genetic disease which leads to cardiac malformations, Marfan syndrome.

The Klinefelter's Syndrome symptoms are determined by the extra X chromosome in the patient's kariotype (the patient's kariotype will be 47 XXY, not 46 XY, like in normal men) . In many men this disease is asymptomatic but it represents one of the most common genetic causes of male sterility.

The newborns and babies with Klinefelter's syndrome have mild hypotonia, reduced muscular strength and may have a slightly slower motor development. These symptoms may go unnoticed, and Klinefelter's syndrome is suspected only if the child has other disorders such as cryptorchidism (the testis's failure to descend into the scrotum), scrotal or inguinal hernias or hypospadias (uretral birth defect) occur. During childhood, the children with this disorder tend to be taller than the children of their age, thin or with a tendency towards obesity, they may have less muscular coordination than the other children, have difficulties in learning how to write and read and their speech skills develop slower.



The symptoms of Klinefelter's syndrome become more marked after the onset of puberty. Because of the reduced amount of testosterone produced, the boy with this disorder have an above average height, a smaller muscular mass, reduced pilosity with a gynoid disposition, wide hips, narrow shoulder, long legs and arms. Another common feature is gynecomastia (large mammary glands / breast enlargement in men) which occurs in almost 30% of patients. The adults with Klinefelter are usually taller than the men in their family.

Infertility is a common feature of this syndrome and is determined by hypogonadism (decreased testicular endocrine function). Microorchidism(small testes) occurs frequently. The men with Klinefelter's syndrome may have normal sex lives but they have azoospermia (no sperm is created ) in 95 to 98% of the cases or oligospermia (very low levels of sperm) in up to 5% of the cases.

The low amounts of testosteron also affect the bone metabolism, leading to weaker bones, an increased risk of fractures and a high predisposition to osteoporosis. Additionally, they have an increased risk of developing serious diseases such as breast cancer, germ cell tumors, rheumatoid arthritis, autoimmune disorders and diabetes mellitus.

The social and psychological development of the teenagers with Kleinfelter's syndrome is affected by the slow development of verbal skills and their poor speech skills. In school they may have problems learning or engaging in sportive activities and have more problems with "fitting in" than other teenagers, and the may also have poor social skills. They have a higher risk of developing depression, substance abuse problems and anxiety disorders. Their emotional problems range from shyness and immaturity to anxiety and aggressivity, but most of them are more quiet, undemanding, more obedient and more helpful and less active and self confident than other boys of their age. These psychological features persist in their adult life. As adults they can have a life similar to the other men, they may have families and friends and have successful careers although they may have to make more efforts in order to performs tasks that require reading or writing.

Alzheimer disease (also known as Alzheimer's) is the most common form of dementia among the elder. The disease is incurable, degenerative and it usually occurs in people over 60 but there have been documented many cases of early-onset Alzheimer's


The early symptoms of Alzheimer's are usually mistaken as the result of stress or are considered to be age-related. The most common early symptom tends to be memory lapses; the patient starts forgetting dates, important events, things he recently learned or information he recently received. As a consequence, the patient starts using memory aides(agenda, notebooks, reminder notes, electronic devices) in order to keep up with his/her usual activities or starts relying on his/her family help.

Another common sign is the fact that many people with Alzheimer's start having language problems and problems related to semantic memory. They may have problems in starting or following casual conversations, they may start forgetting the names of common objects, of friends and even family and they sometimes start using the definition of an object instead of its name.

The abstract thinking is also impaired, affecting abilities such as working with numbers, the ability to develop plans and to follow them and usually simple tasks such as following recipes, keeping track of household expenses and bills become much harder and take longer than prior to the onset of the disease. Performing familiar task may also be more difficult and so there may occur problems at work, at home or in social contexts.

Vision problems may be an early symptom of Alzheimer's disease when the patient starts having problems in reading a simple text, appreciating the colors, the contrasts or the distances. The people with Alzheimer's disease may also experience disorientation; they may become lost in otherwise familiar places, they may not know where they are , why, when and how did they get there and they may also lose track of time, dates and sometimes even seasons.

Misplacing an object is something that happens to anyone but in Alzheimer's disease the patients usually put important objects in odd and unusual places and afterwords they are unable to find them. In some cases they may even start accusing the others of stealing their things (especially keys, wallets, valuable items). As the disease progresses, this feature's frequency increases.



Judgment is also affected by Alzheimer's. The patient may spend large amounts of money for things they will never use, present a reduced interest in housekeeping or personal hygiene.

Withdrawal from both social and professional activities is not only a consequence of the embarrassment caused by the features mentioned earlier but also an important psychiatric symptom. The patient's withdrawal from his usual interest is accompanied by forgetting how to complete activities such as games, hobbies, losing interest in social contacts or business and an increased need for sleep. Personality and mood changes occur in all the people with Alzheimer's disease. They may become irritable, depressed, anxious, suspicious, confused and grumpy, have rapid mood swings or be dependent of one of the family members. Aggressivity and stubbornness are not unusual , especially if the patient is outside his/her comfort zone.

Congestive heart disease is a misapplied term used when referring to a disorder named congestive heart failure (CHF); another mistake people make when talking or reading about this condition is that they don't know that the initials CHD which refers to congenital heart defects (which may be accompanied by congestive heart failure fact that confuses even more the people).


The symptoms of congestive heart failure occur in patients who have an abnormality (inherited or acquired) in heart structure or functioning. There are many causes that lead to this condition, the most frequent being miocardic infarction, miocardic ischemia, hypertension, genetic disorders, valvular diseases and infiltrative diseases.

The most common symptoms of congestive heart failure are fatigue and dyspnea. Fatigue is determined not only by the low cardiac output but also by the associated non-cardiac co-morbidities. Dyspnea occurs in the early stages only after exertion but, as the disease progresses it occurs after any physical activity and,ultimately it occurs even at rest. Orthopnea (shortness of breath while lying flat) and paroxysmal nocturnal dyspnea (severe breathlessness and coughing attacks in the nighttime, awakening the patient) are common in the late stages of the disease. Orthopnea may be relieved by sitting upright, unlike paroxysmal nocturnal dyspnea. Another respiratory feature of the disease is represented by the Cheyne-Stokes respiration. This sign consists in severe episodes of dyspnea or short, transient cessations of breathing.

The patient also complain of gatrointestinal symptoms such as fullness, nausea, anorexia, abdominal pain and early satiety, determined by a congested liver or the edema of the bowel. The congestion of the liver and the stretching of Glisson's capsule ill also lead to right-upper quadrant pain.

In patient with severe congestive heart failure neurological symptoms may occur. Sleep disturbances, confusion, mood disturbances and disorientation are common, especially among the elderly patients.

A very important sign is represented by hepatomegaly. When this sign is present the enlarged liver is tender and pulsates during systole in case tricuspid regurgitation is present. As a consequence of the increased blood pressure in the hepatic veins, ascites occurs. The liver congestion leads to an impaired hepatic function, whose consequence is jaundice, another late sign of congestive heart failure.

A cardinal sign of congestive heart failure is peripheral edema which occurs mainly in the pretibial region and in the ankles. In bedridden patients presacral edema may be found.

In the severe cases of the disease massive weight loss and cachexia may be found. These feature have not been entirely explained but they are considered to be multifactorial and determined by the anorexia, impairment of the intestinal function, nausea, vomiting due to abdominal fullness and hepatic congestion.

Other less specific signs and symptoms are: decreased daytime micturition, nocturia, postural light headedness, falls and muscle wasting. Other symptoms, determined by hypoxemia are severe cyanosis and impaired mental performance.

Pick's disease is a neurological disease which determines a rare type of dementia (frontotemporal dementia). The disease usually affects people of 40-55 years old but there have been documented cases of patient younger than 30 or older than 60; it has also been noticed that the disease affects more womnt than men. The disease causes the brain cells to shrink due to the apparition inside the brain cells of large proteic aggregates, also known as Pick's bodies. Although that the disease has similar symptoms to other diseases that cause frontotemporal dementia (eg Alzheimer) in Pick's disease the brain damage is focal, not diffuse.


The symptoms of Pick's disease, especially in the early stages are determinned by frontal lobe damage. This is why the first symptoms are affecting emotional functioning and social skills (unlike in Alzheimer's disease where the memory is impaired first). The patient presents mood swings, desinhibition, euphoria, light headaches and his social abilities deteriorate. At the beginning of the disease the behavioral changes may go unnoticed but as the disease progresses, the patient may become extremely withdrawn or extroverted, his / her sexual behavior may change and there may be noticed an increased libido. This feature and  other symptoms such as aggressivity, impatience, rudeness and the loss of inhibition may be very disturbing and it may even make necessary law enforcement  interventions.

In the early stages of the disease language problems may occur. The patient has difficulties in naming objects or finding words; instead of finding the word to name an object the patient will describe it; but these problems are not marked.


As the disease progresses the patient's alimentary habits changes. The person with Pick's disease may have an increased appetite, even gluttony, he/she may manifest an obsessive-compulsive behavior towards food such as overeating or eating only a few or even one type of food. Excessive drinking (alcohol) occurs, although prior the onset of Pick's disease the patient did not have drinking problems.

All this disturbances plus the inability to function in social contexts, the affected judgment, and the difficulties in keeping a line of thought will make the patient unable to find or keep a job.




In time the language difficulties increase; echolalia (repeating words other people say), aphasia (difficulties in understanding speech or difficulties in speaking) may occur and writing and reading abilities are affected as well. Other emotional changes become more obvious: lack of empathy or warmth, a decreased interest in daily activities, impulsivity and lack of interest concerning personal hygiene.

There may also appear physical and neurological symptoms: urinary incontinence, weakness, stiffness and muscle rigidity, lack of movement coordination and progressive memory loss.

Unfortunately there is no treatment or cure for Pick's disease and the disease always leads to deterioration but there are treatments that ameliorate the behavioral problems; speech and occupational therapy may also be useful and behavioral modification techniques may have an impact on social integration. The life expectancy in Pick's disease it's usually 2-15 years and so, the treatment must focus on improving the patient's life quality.

Mercer disease is an extremely contagious disease caused by Methicillin Resistant Staphylococcus Aureus and therefore the disease is mostly known as MRSA infection. This bacteria is frequently acquired in hospitals, dialysis centers, nursing home and other health care facilities (health care associated MRSA). The health care associated MRSA affects mostly immunocompromised patients and old patients. Another type of MRSA has been discovered in otherwise healthy people in wider communities ( community associated MRSA) which is responsible for serious forms of pneumonia and skin infections.



The first symptoms in MRSA skin infections (the most common type of infection) are small red bumps like boils (the infection of hair follicles), pimples, abscesses (the infection of subcutaneous soft tissue), carbuncles (severe abscesses from which pus is draining), celulitis (the infection of fatty tissue ) or impetigo( superficial skin infection which appears as pus-filled vesicles). In short time, these skin conditions increase their severity, their surface increases, they become more painful,  and the patient develops more symptoms such as malaise, fever, and rashes. Although these skin conditions may be effectively treated, some community acquired MRSA strains may be highly virulent and may spread rapidly causing serious complications like sepsis, necrotizing fasciitis, toxic shock syndrome, necrotising pneumonia, pyomiositosis and infective endocarditis.




Necrotising fasciitis is a serious, deep infection of the subcutaneous tissue. Its symptoms are pain, subcutaneous swelling, crepitus, normal or reddish aspect of the skin in the first stage and skin necrosis and dark bullae in later stages. Necrotising fasciitis may be determined not only by Methicillin Resistant Staphylococcus Aureus, but also by other strains of bacteria and so, the antibiotic must be chosen after a microbiological analysis of the tissue.

Pyomiositosis is a deep muscular infection (it affects skeletal muscles, especially the quadriceps and the gluteal muscular group) and its symptoms are muscle swelling, pain, and high fever. The skin is usually minimally involved.

The pneumonia produced by MRSA is usually the result of a nosocomial (acquired during hospitalization) infection. Its features are not very different to those produced by other types of bacteria. The patient presents fever, cough with large quantities of purulent sputum and respiratory distress. The diagnosis is made after sputum cultures and Gram coloration.

TSS or toxic shock syndrome may be caused not only by MRSA but virtually by all Staphylococcus aureus strains. It is determined by the different bacterial toxins and its symptoms are: malaise, high fever, low blood pressure, characteristic rash, gastrointestinal disturbances (such as vomiting and diarrhea). Toxic shock syndrome progresses fast, leading to renal failure, hepatic inflammation, central nervous system involvement (confusion, stupor, coma). THis is a severe disorder and it frequently requires hospitalization.

Infective endocarditis occurs mainly in patients with intra-vascular devices, immunosupressed, that are going through hemodialysis, or patients with intra-vascular prosthetic devices. Most commonly the patient complains of fever, chills, night sweats, fatigue, shortness of breath, pleuritic chest pai. The clinical exam reveals muscular, red or hemorrhagic, painless patches on palms or soles known as Janeway's lesions, petechiae, splinter hemorrhage, and oval, pale retinal lesions surrounded by hemorrhage known as Roth's spots. Neurological manifestations may occur due to central nervous system embolization.

Crohn's disease consist in the chronic inflammation of the gatrointestinal tract. It commonly affects the colon or the distal ileum but it may affect virtually any part of the digestive tract. The causes of this disease are not certainly known but many authors consider it an autoimmune disorder (determined by an improper immune response). There are clues that suggest a hereditary predisposition to the disease; also smoking seems to have a contribution in triggering the attacks and affecting the course of the disease. Depending on the segment affected the disease may present as jejunoileitis, ileocolitis, colitis and perianal disease, or gastroduodenal disease.

In all these clinic forms of the disease, the first symptom of the disease is in most cases chronic diarrhea (especially if the patient complaining of this symptom has had surgery), accompanied by low-grade fever, anorexia, abdominal pain and weight loss.

In ileocolitis (the most common form of the disease) the signs and symptoms are chronic diarrhea, colicky lower right quadrant pain, a palpable mass in the same quadrant and fever. As a consequence of diarrhea, fear of eating and anorexia the patient suffers a weight loss of up to 20% of his body weight. The mass consists in swollen bowel and mesentery amd it may compress the right ureter leading to dysuria. Bowel obstruction causes symptoms that vary in intensity from postprandial pain to fibrostenotic stricture (over the years). Severe inflammation may lead to wall thinning thus leading to fistula formation to the adiacent structures (bowl, skin, mesenteric abscess).

Jejunoileitis determines loss of digestive surface, thus leading to malabsorbtion (followed by nutritional deficiencies) and steatorrhea. Diarrhea is a characteristic symptom. The nutritional deficiencies may have serious consequences such as pellagra (a severe disorder caused by niacin deficit) and  megaloblastic anemia (due to lack of vitamin B12).

The signs and symptoms of colitis ans perianal disease are diarrhea, fever, malaise, crampy abdominal pain, rectal bleeding. Due to colon strictures the patient may present symptoms of bowel obstruction. The disease may produce fistulas into the stomach and duodenum ,thus leading to feculent
vomiting, and 12% of women suffering of Crohn's disease will develop a rectovaginal fistula. Perianal disease occurs in 35% of patients with Crohn colitis and its symptoms are large hemorrhoidal tags, anorectal fistulae, anal strictures, incontinence and perirectal abscesses.

In gatroduodenal disease the symptoms are: nausea, vomiting and pain in the epigastric region.

Crohn's disease may have extra-intestinal symptoms too. The dermatological manifestations of the disease are perianal skin tags (up to 80% of the patients with Crohn's colitis), erythema nodosum (up to 17% of the patients) which consists in red nodules, measuring up to 5 cm in diameter on the calves, thighs and arms and pyoderma gangrenosum (just 7% of cases). The rheumatologic manifestations occur in 15 to 20% of cases and they are represented by ankylosing spondilitis and peripheral artritis. These manifestations worsen as the disease progresses.

Inspite the fact that anthrax has been usually observed in well defined areas or as an occupational hazard , nowdays it is very important due to its potential use as a biological weapon. Anthrax it is mainly a zoonosis; it mainly affects herbivores (horses, cattle, sheep), who come in contact with Bacillus antracis spores that contamine their pastures. The people are infected usually by direct contact with animals or their contaminated biological
The disease has three forms, with different symptoms and progression: cutaneous, pulmonary and gastrointestinal. In all three forms of the disease meningitis and sepsis may occur due to the lymphematogenous dissemination of bacteria from a primary lesion.

Cutaneous anthrax is the most frequent form of the disease (95% of cases). The bacteria or the spores are being inocculated into the skin through a cut, scratch, or insect bite. After two to five days (in some cases the incubation period lasts up to 3 weeks), at the infection site it appears an initial lesion, an erythematous papule which may be mistaken as an insect bite. In 2-4 days the papule enlarges and it is surrounded by a ring of small vesicles. The area surrounding this lesion is eritematous and edematous. The lesions' diameter is 1-3 cm, it is not painful and pus is absent. When the vesicular ring ruptures (day 7-12) the clear fluid from the vesicles is being discharged and the lesion progresses into an eschar - a specific black necrotic lesion which heals slowly (up to 60 days).Other symptoms are: regional lymphadenopathy, fever, malaise and headaches

In cutaneous anthrax, if the patient receives adequate treatment, mortality is rare; nevertheless in severe cases, less commonly the disease may progress with toxemia, bacteremia, massive local edema and painful adenomegaly, shock and fatal outcome.

Gastrointestinal anthrax is determined by the ingestion of spores in contaminated water or food. After the incubation period wich lasts up to one week, the disease may have two clinical forms: intestinal or oropharyngeal.

Initially the symptoms of intestinal anthrax are non-specific: fever, malaise, vomiting, nausea and anorexia. Later on, the disease progresses and severe abdominal pain, massive ascites, hematemesis (vomiting blood) and bloody diarrhea appear. Toxemia develops, then shock, leading to death (25% to 60% of cases).

In oropharyngeal anthrax the lesion is more frequently localized on the tongue, the buccal mucous membrane, the posterior pharyngeal wall or the tonsils. The main symptoms in this form of the disease are: sore throat, high fever, dysphagia, local lymphadenopathy. The infection may lead to bacteremia and toxemia thus leading to shock and death, in spite of the treatment (50% mortality).

The inhalation of spores leads to pulmonary anthrax. Its initial symptoms are insidious and are similar to a cold. After a short incubation (up to 1 week) the disease begins with unproductive cough, fever, malaise, dyspnea. In a few days the illness worsens and progresses to its next stage characterized by high fever, cianosis, dyspnea, respiratory distress. The bacteria spreads massively to CNS ad bloodstream and toxemia occurs.Once bacteremia has developed the progression to shock and death is very rapid. In spite treatment, pulmonary anthrax is, in most cases, fatal.
