Слайд 2The icteric color of skin (jaundice) is a noticeable sign.
It is observed at many infectious and noninfectious diseases.
Very
often groundlessly diagnosis of viral hepatitis is put at jaundice (30-40% − by mistaken diagnosis).
General sign for all jaundices is increase of level of bilirubin in the serum of blood.
It can be caused by other reasons (acrichine, carotin), i.e. not by increased bilirubinemia.
Слайд 3At differential diagnostics of jaundices it is necessary:
Decision of question
about the presence of veritable jaundice, i.e. to eliminate other
reasons of color of skin.
To eliminate or confirm the jaundice related to aqute infectious pathology.
To eliminate or confirm the jaundice related to aqute surgical pathology.
Слайд 6At hepatic insufficiency urobilinogen is not taken by hepatocytes and
distinguished with urine, oxidizing on air to the urobilin.
At viral
hepatitis:
Mainly II phase is disturbed, i.e. activity of capture of free bilirubin goes down from the Disse's space (because of disfunction of hepatocyte), as a result the level of free bilirubin grows in blood.
IV phase is disturbed to because of conjugated bilirubin is excreted not in a bilious capillary and through the sinewave poles of hepatocytes in Disse’s space and then gets in blood.
Other stages are changed smaller and increase of general bilirubin is mainly due to direct bilirubin.
Слайд 7At a cholestatic variant:
an excretion and movement of bilirubin
(IV phase) are considerably disturbed,
thrombuses appear in bilious
capillars.
it results in conjugated bilirubin and other components of bile (bilious acids, cholesterol) enter Disse’s space and blood.
disturbance of passableness of bilious channels, for example, at biliary obstruction by a stone.
Слайд 8On pathogenesis hemolytic hepatic and subhepatic (cholestatic) jaundices are distinguished
usually.
Hemolytic jaundice is conditioned by increased disintegration of RBC
and increased formation of bilirubin, insufficiency of capture by liver.
Different types of hemolytic jaundice:
defects of RBC,
autoimmune hemolytic jaundices,
resorbable massive haematomas,
infarction.
Слайд 9Hepatic jaundices are conditioned by the injury of hepatocytes and,
maybe, cholangiols.
By leading mechanism it is possible to distinguish
a few variants.
disturbance of excretion and capture of bilirubin, regurgitation of bilirubin (at a hepatocellular jaundice at sharp and chronic hepatitis, sharp and chronic hepatosis, hepatocirrhosis).
excretion of bilirubin is disturbed and regurgitation presents at cholestatic jaundice, cholestatic hepatitis, primary biliar hepatocirrhosis, idiopathic cholestasis.
disturbance of conjugation and capture of bilirubin can be at enzymopathic jaundice at the Gilbert's syndrome and other benign familial icteruses
disturbance of excretion of bilirubin can be at the Dubin-Johnson syndrome and Rotor syndrome.
Слайд 10Subhepatic jaundices arise up as a result of disturbance of
passableness of bilious channels, a leading mechanism here is disturbance
of excretion and regurgitation of bilirubin.
By the character of biliary obstruction subhepatic jaundices is subdivided on:
intrachannelar (at biliary obstruction of bilious channels by stones, tumour, vorms, inflammatory exsudate, detritus of tissue),
extrachannelar (conditioned by the prelum of channels from outside by a tumour, Echinococcus, narrowing by scars.
During realization differential diagnosticians of jaundices it is needed to define belonging of jaundice to that or another to the group, and then already to conduct differentiation into a group.
Слайд 11SUPRAHEPATIC JAUNDICE
It develops as a result of enhanceable products of
bilirubin and insufficiency (relative) of function of its capture.
The
increased disintegration of RBC (hemolysis) is basic in genesis, therefore usually it named hemolytic.
Main reason is out of liver − plenty of free bilirubin appears as a result of the increased disintegration of RBC that liver is unable to take (relative insufficiency), intracellular transport of pigment is disturbed probably too.
Слайд 12Because of the increased secretion of bilirubin in a bile
maintenance of urobilin bodies increases in an excrement and urine.
Enhanceable maintenance of bilirubin in blood is conditioned by the accumulation of free (indirect) bilirubin.
At massive hemolysis hepatocytes not always are able to excrete all conjugated bilirubin, as a result maintenance of the conjugated bilirubin sometimes rises in blood.
The level of jaundice at this form depends:
from massiveness of hemolysisа,
from functional state of liver (hepatocytes).
Слайд 13It is necessary to remember about possibility of combined genesis
of jaundices at some infectious diseases (leptospirosis, sepsis).
Hemolysis and
damage of hepatocytes by causative agent or it’s toxins.
Hemolysis can be druginduced (quinine, Sulfanilamidums) and damage of hepatocyte − by a causative agent (hemoglobinuric fever at a malaria).
For the decision of question about suprahepatic character of jaundice the complex of clinical and laboratory data is used.
Слайд 14Main sign of suprahepatic jaundice − hyperbilirubinemia due to a
free (indirect) bilirubin (bilirubinic coefficient − attitude of the conjugated
bilirubin toward his general amount) not high (less than 50%).
Important clinical signs:
absence of acholia;
presence of pleochromic bile and dark colouring of excrement and urine (increase of urobilinogen);
the jaundice of skin and sclera is moderate;
skin as a rule, pale (anaemia as a result of hemolysis);
liver and spleen can be enlarged, but the function of liver substantially is not broken (livers biopsy without considerable changes);
anaemia, increase of amount of reticulocytes (strengthening of regeneration of RBC) in peripheral blood, sometimes change of form of RBC (anisocytosis and other)
Слайд 15At diagnostic of suprahepatic (hemolytic) character of jaundice it is
necessary to specify type. 3 types are distinguished.
At a corpuscular
hemolytic jaundice principal reason can be biochemical defects:
inherited enzymopathy RBC (deficiency of G6-PDG),
microspherocytosis,
hemoglobinopathys (thalassemia of and other),
defects of membranes of RBC (paroxysmal hemoglobinuria and other).
Слайд 16At extracorpuscular hemolyticой anaemia enhanceable hemolysis is conditioned by the
action of different factors being in plasma of blood :
antibodies
(for example, action of isoantibodies as a result of incompatible blood transfusion),
hemolysisines of different causative agents (viruses, Leptospira, causative agents of sepsis).
influence of disease causing (plasmodia of malaria) agent;
at the action of hemolytic poisons (arsenic, sulphuretted hydrogen of and other).
Слайд 17Third type − increase of products of bilirubin as a
result of disintegration of RBC :
haematomas,
heart attacks,
hemorrhages in
abdominal or pleural cavities.
At anamnesis:
third type of hemolytic jaundice :
haematomas, hemorrhages (traumas, signs of the internal bleeding)
clinical symptomatology of heart attacks of myocardium, lung.
Слайд 18At anamnesis:
Corpuscular hemolytic jaundice often is repeated at persons with
insufficiency of G6-PDG provoked by some drug (quinine, Sulfanilamidums NSAD)
and accompanied by:
ferver (hemoglobinuric fever),
brown urine with large sediment,
anemia.
more often observed at patients with malaria.
Слайд 19Possibilities of differential diagnostics.
Hereditary microspherocytosis:
related to the defect of membrane
of RBC (enhanceable disintegration of RBC),
anaemia,
increase of spleen,
formation
of stones is in a gall-bladder,
Нв decreases 40-50 g/l
can be provoked by different infectious diseases,
amount of bilirubin rises up to 50-75 mcmoll/l due to indirect bilirubin,
misdiagnosis of chronic hepatitis and even hepatocirrhosis is often put,
the diameter of RBC is diminished, and a thickness is enlarged, form is spherical,
amount of reticulocyteов is enhanceable,
diagnostics is difficult at combination with a cholestasis.
Слайд 20Hereditary stomacytosis (described in 1961 г) :
defect of membranes of
RBC,
the form of RBC is original the unpainted part in
their center is delimited by two bent lines and some reminds a mouth (from here the name of illness),
expressed anaemia (Нв 70-90 g/l out of crysis and 30-50 g/l during crysis),
increase of spleen,
jaundice due to an indirect bilirubin.
Слайд 21Jaundice at the hereditary hemolytic anaemia conditioned by the deficit
of G6-PDG:
most widespread anomaly of RBC,
often conditioned by the
reception of drugs during treatment of some infectious diseases,
most often meets in the countries of Africa, Latin America, on the coast of Mediterranean, in Azerbaijan (to 9,9% population), rarer in other regions(2-4%),
often provoked by Sulfanilamids, antimalarials (quinine, примахин, acrichine), nitrofurans, quinolons, derivatis of isonicotinic acid, para-aminosalicylic acid.
usually it appears on a 2-3th day from the start of treatment,
Слайд 22hemolytic crysis is usually named a hemoglobinuric fever.
in the start
− moderate jaundice, dark urine,
on the 4-5th day heavy hemolytic
crysis with brown urine,
the temperature rises, sharp headache appears, vomiting and diarrhoea are possible, jaundice grows,
Нв decreases to 20-30 g/l
differentiating is necessary from other hemolytic jaundices.
Слайд 23Thalassemia:
it is contingented by the hereditary disturbance of synthesis of
hematohistone,
jaundice, considerable increase of liver and spleen,
bilirubin in blood is
enhanceable due to direct faction of pigment,
Where are reticulocytosis, anisocytosis, poykilocytosis, basophilic including in RBC at peripheral blood.
Слайд 24Autoimmune hemolytic anaemias:
idiopathic (reason is unknown),
symptomatic (develop at
many illnesses: myelomatosis, lymphatic leukemia, lymphosarcoma, system red lupus, pseudorheumatism,
ulcerous colitis).
can be provoked by many infectious diseases (measles, rubella, epidemic parotitis, quinsy, etc.) when jaundice is not typical usually.
Слайд 25Autoimmune hemolytic anaemia with incomplete thermal agglutinins:
must be taken into
account at idiopathic and symptomatic hemolytic jaundices,
start of illness is
sharp or even stormy with growth of jaundice,
sharp weakness, pains in area of heart, shortness of breath, pains in back, palpitation, fever,
misdiagnosis of viral hepatitis is often put,
can begin gradually with pains in joints, stomach-ache, weakness,
Слайд 26subfebrile fever, pallor of the skin and moderate jaundice,
liver and
spleen, as a rule, are enlarged,
bilirubin is enhanceable up to
40-60 mcmoll/l due to indirect faction,
in blood the − amount of reticulocyteов is enhanceable, macrocytosis and/or microspherocytosis, sometimes fragmented destroyed RBC,
osmotic resistence of RBC is decreased.
Слайд 27paroxysmal night hemoglobinuria :
purchased form of the hemolytic anaemia related
to the change of structure of RBC,
leucocytes and thrombocytes are
damaged also,
the amount of uniform elements decreases,
gradual start, weakness, moderate jaundice,
headache, stomach-aches (thrombosis of mesenteric vessels sometimes is operated with suspicion on appendicitis or other surgical disease),
a liver and spleen are mildly enlarged,
Слайд 28the excretion of hemosiderin is characteristic at urine (dark color
of urine in default of RBC in it),
proteinuria is expressed,
the benzidine test with urine is positive,
Нв in the period of intensifying decreased (30-50 g/l), at the period of remission it is normal,
bilirubin in blood is mildly enhanceable due to indirect faction,

the level of iron in blood is decreased due to loses with urine.
Слайд 29During heavy lead-poisoning:
excretion with urine of hemosiderin in combination
with stomach-aches and anaemia,
polyneuritis absent at night hemoglobinuria is
characteristic.
Other variants of suprahepatic jaundices are rarely.
Слайд 30HEPATIC JAUNDICES
If patient really has a jaundice and the different
variants of hemolyticой (suprahepatic) jaundice are excluded, the most difficult
stage of differential diagnostics of jaundices - differentiation of hepatic jaundices, because of the large number of infectious and uninfectious diseases have a hepatic jaundice:
Слайд 31viral hepatitis A, B, C, Д, Е, F, G;
herpetic hepatitis;
CMV
hepatitis;
yellow fever;
infectious mononucleosis
typhus recurrens
intestinal yersiniosis;
psittacosis;
leptospirosis;
pseudotuberculosis;
salmonellosis;
glanderss;
sepsis;
listeriosis;
amoeba damage of liver;
syphilis;
toxic hepatitis:
aqute alcoholic
hepatitis;
other hepatitises
Слайд 32For differential diagnostics of infectious and toxic hepatitis presence of
signs of aqute infectious process (fever, signs of general intoxication,
exanthema, epidemiology these and other) has a large value.
For diagnostics of toxic hepatitis matter the use of hepatotoxic substances (antiphthisic preparations, inhibitors of МАО, derivatives of phenotiasin), technical liquids (dichlorethane, ethyleneglycol), occupational hazard (work with oxidants on the basis of nitric acid, hydrazone and other), and also absence of signs of infectious process.
Слайд 33For the decision of question about the presence of aqute
viral hepatitis :
to compare fever and other signs of general
intoxication with the degree of damage of liver.
At VHA and B fervescence and other signs of infectious toxicosis expressed unaqutely and mainly in the initial stages of illness.
At appearance and development of jaundice the temperature of body goes down, and the signs of general intoxication are expressed poorly (at VHA).
Differentiation of VHA and other causes difficulty, especially as their combination is possible.
VHA is possible more often at the persons of young age, sometimes − as epidemic infective episode, contacts with sick VHA presents in the terms laid in a latent period (more often 15-30 days).
Слайд 34In age 25-40 VHA durats heavier.
Duration of preicteric period at
VHA is some shorter (up to 5-7 days) than at
VHB (more often 1-4 weeks.).
At VHA joint pains disturb rarer, more often flu-like syndrom, dyspepsia and asthenovegetative syndroms present at the pre-icteric period, at the end of pre-icteric period urine becomes dark and an excrement is discoloured.
The icteric period of HA begin with appearance of icteritiousness sclera, mucous membranes of pharynx, and then skin. Intensity of jaundice grows during a week. The temperature of body is normal, weakness, sleepiness, decline of appetite, pains in right hypochondrium, for some patients skin itch present.
A liver is enlarged, indurated and some painful, there is an increase of spleen at 20-50% of patients .
There is leucopenia (sometimes normocytosis), neutropenia, relative lymphomonocytosis, ESR is a 2-4 mm/h in peripheral blood.
Maintenance of general bilirubin is enhanceable mainly due to direct (conjugated).
Слайд 35Activity of transferases rises considerably, especially ALT, the indexes of
thymol test are enlarged, a prothrombin index is decreased. An
icteric period lasts 7-15 days. At most patients of VHA a bilirubinemia does not exceed 80-90 mcmoll/l (5 mgs%).
A decubation is characterized by a fast disappearance of clinical and biochemical signs of hepatitis.
Biochemical indexes are usually normalized to the 20-25th day from the moment of appearance of jaundices.
The severe forms of VHA are observed rarely, chronic forms, as governed, does not develop.
Слайд 36Viral hepatitis B
It is transmitted by mainly parenteral way
and latent period is more often 60-120 days.
Pre-icteric period more
long often with joint pains. More often dyspepsia and joint pains start at the pre-icteric period.
At 10% of patients short-term urticarial rash is marked.
At the end of pre-icteric period urine becomes dark, and an excrement is discoloured, the increase of liver is marked, activity of AST rises more than ALT.
Icteric period at VHB, as a rule, is prolonged and characterized by expressed and stable clinical signs.
An jaundice arrives at a maximum on a 2-3th week.
At severe forms already on the first days of jaundice aqute hepatic insufficiency (hepatic coma) can develop on a background of worsening of the state.
Слайд 37An jaundice grows gradually, the expressed, as a rule, is
proportional to severity of illness (exceptions is possible).
The sizes of
liver are enlarged. A spleen is often enlarged.
Reduction of sizes of liver at an increasing jaundice is an unfavorable sign.
Bradycardia and hypotension are characteristic.
The period of recovery is more protracted, than at VHA.
The dyspepsia and asthenic syndrome can save long time.
Recovery, prolonged and chronic forms of viral hepatitis are clinical outcomes.
At part of patients (about 0,2%) hepatocirrhosis can develop in future. Laboratory discovery of Ag and/or Ab of VHB confirm diagnosis.
Слайд 38At the generalized forms of viral infection (herpetic, CMV), or
septic bacillosiss appearance of jaundice takes place on a background
a high fever and expressed symptoms of general intoxication (haemodynamic disorders, damage of the central nervous system and other) and different organ damages peculiar to one or another infectious disease, are not characteristic for VHA and VHВ.
Слайд 39Aqute herpetic hepatitis.
Usually durats latently, periodically (often on a
background a flu and other illnesses) passes to the clinical
form.
It is observed rarely and one of frequent signs of generalized, very severe herpetic infection.
Aqute suppression of immunity (reception of immunodepressants, cytostatics, prolonged reception of large doses of corticosteroids, radiologic therapy, AIDS and other) is preceded. The isolated herpetic hepatitis is impossible.
Damages of skin and mucous membranes are typical.
Different organ damages combine usually − herpetic encephalitis, viral-bacterial pneumonia and herpetic hepatitis.
The symptoms of general intoxication are aqutely expressed.
Illness durats severe, lethality about 30%.
Слайд 40Aqute CMV hepatitis.
CMV-INFECTION is widespread as a latent form.
For women CMV-INFECTION can stipulate the severe antenatal infection of
fetus. Innate CMV-INFECTION is characterized by an jaundice, defects of development and often results in death of children.
Acquired CMV-INFECTION in a aqute period develops as an easy flu-like disease, and then passes to the latent form, at that CMV saved in an organism.
At the fall-off of immune defence a generalized form (patients by AIDS, on a background other the diseases − leukemia, cancer, severe surgical operations and other) can develop from latent.
Clinically − high fever, increase of liver and spleen, jaundice.
A liver is considerably enlarged, painful at palpation.
Practically always pneumonia viral etiology develops, antibiotic therapy is not effective.
An encephalitis develops often.
There are not a herpetic exanthema at CMV-INFECTION.
Слайд 41Innate CMV-INFECTION at new-born

aqute hepatitis, hemorragic syndrome, encephalitis.
An jaundice grows 2-3 weeks
and in 2-6 months goes down
Activity of transferases and ALKALINE PHOSPHATASE is enhanceable.
There can be defects of development, innate damages of eyes (cataract, chorioretinitis, atrophy of visual nerve).
The number of thrombocytes is considerably decreased, anaemia develops.
For confirmation of diagnosis of CMV-INFECTION − cytological research of of saliva, urine, CSF : finding out the cytomegalic cells.
Слайд 42Icteric form of infectious mononucleosis.
Aqute hepatitis caused by a
virus Epstein-Barr does not behave to viral hepatitises.
Jaundice of
hepatic genesis, increase of liver, increase of activity of serum enzymes — ALT, AST, ALKALINE PHOSPHATASE and other present.
Expressed syndrome of general intoxication (fervescence up to 39-40 °C, general weakness, headache and other), saves and sometimes grows after appearance of jaundice.
The basic signs of infectious mononucleosis for differential diagnostics are following: а) fever; б) tonsillitis; с) generalized lymphadenopathy; д) increase of liver and spleen; е) characteristic changes of peripheral blood.
A diagnosis is confirmed by ELISA and/or PCR.
Слайд 43Yellow fever.
Quarantine endemic illness of the countries of South
America and equatorial Africa.

Слайд 44Nausea and vomiting, hyperemia of mucous membrane of oral cavity
appear on a 2th day, on the 3-4th day −
jaundice.
There is a very short remission on the 5th day of illness, later the temperature increases again and hemorragic syndrome appears.
Tachycardia is replaced by bradycardia (40-50 in a minute), BP decreases.
Death comes from aqute kidney insufficiency or from infectious-toxic shock.
At a favourable end from a 7-9th day the state begins to get better.
A diagnosis is confirmed by specific laboratory data.
Слайд 45At all bacterial hepatitis the same signs at other hepatitis
are marked: increase of liver (quite often spleens), considerable increase
of level of bilirubin, hepatic character of jaundice, substantial increase of activity of serum enzymes (ALT, AST).
Differences from viral hepatitis A and B are aqutely expressed infectious syndrome and damage of different organs and systems.

Start is aqute, body temperature 38-40 °С.
The injection of vessels of sclera, hyperaemia of face, neck, upper departments of trunk («symptom of hood») appear early.
Слайд 49Punctulated («scarlatiniform») exanthema more often on the 3th day of
illness is abundant and placed on all body with a
concentration in area of natural folds of skin (ulnar bends, inguinal areas of and other) is characteristical.
Skin of hands and soles is hyperaemic, tongue bright red with enlarged papillae, without a coat («raspberry tongue»).

Bilirubinic- transferases dissociation (the degree of increase of ALT some falls behind from the level of hyperbilirubinemia).
Слайд 60Medicamental hepatitis
Conditioned by many drugs.
Often at the reception of
drug long time and in large doses. More than half
of cases − application of antiphthisic drugs. Except an jaundice and increase livers can be other signs of medicinal illness: dyspepsia disorders, allergic disturbances.
The cyclicity of development of disease is absent.
The indexes of thymol test are negative.
Morphologically − picture of aqute infiltration hepatitis, and at VH aqute destructive hepatitis is typical.
Слайд 61Toxic hepatitis at poisoning pesticide
The symptoms of hepatitis appear
on the 2-3th day of poisoning.
Clinically (depending on the type
of poison) for differential diagnostics a basic value are:
information about a contact or use of poisons or technical liquid;
symptomatology of initial period of «drunkenness»;
the period of brief improvement is possible;
combination of signs of toxic hepatitis with a damage GIT, CNS, kidneys.
Слайд 62Prolonged jaundices (during many months and years in the stage
of intensifying or remission):
chronic hepatitis (including - autoimmune),
hepatocirrhosiss,

change of proteins of plasma (decline of albumens and increase of globulins);
activity of serum enzymes (AST, ALT, ALKALINE PHOSPHATASE) is mildly enhanceable.
Слайд 66Gilbert's Syndrome (hereditary pigmental hepatosis) :
starts in young or
juvenile age and expressed in the chronic, periodically appearing mildly
expressed jaundice;
conditioned by the increase of free bilirubin, in default of complex of signs of hemolytic jaundices (change of mechanical and osmotic resistance of RBC, their morphology, considerable increase of liver and spleen and other).
Crigler-Najjar syndrome is similar with the Gilbert's Syndrome, but appears from the period of new-bornness, maintenance only of free bilirubin rises.
Слайд 67Dubin-Jhonsson Syndrome:
observed in juvenile and young age;
hyperbilirubinemia due to
mainly conjugated or in an equal degree free and conjugated
factions of pigment;
bilirubinuria;
at cholecystography bilious ways are not filled or filled poorly;
morphologically − in tissue of liver accumulation of characteristic dark pigment («black liver»).
Rotor syndrome:
more often in child's age;
mainly conjugated bilirubin accumulates in blood;
bilirubinuria;
morphologically - no pathology of liver;
cholecystography − bilious ways are not filled after intravenous introduction of contrasting substance.
Слайд 68SUBHEPATIC JAUNDICES
Conditioned by disturbance of leadingout of bilirubin through bilious
channels with the regurgitation of it, and also decline of
excretion of bilirubin from hepatocytes.
A pathological process is localized out of liver in the main bilious channels − mechanical jaundices.
Слайд 69Subhepatic jaundices can be conditioned by many factors:
closing (obstruction)
hepatic and general bilious channels from within by gall-stones, helmints
of and other;
by the compression of general bilious channel outside (tumor, enlarged lymphatic nodes);
stenosis of general bilious channel by scars and jointins (after operative intervention, inflammatory process);
atresia (hypoplasia) of bilious ways.
Слайд 70At subhepatic jaundices:
Maintenance of the conjugated (direct) bilirubin rises mainly.
After the obstruction of bilious channels the excretion of bile
from hepatocytes proceeds somet time.
The increase of pressure in bilious channels results in the secondary changes of hepatocytes, as a result the excretory function of hepatic cells goes down and paracholia comes, i.e. intrahepatic cholestasis. The increase of level of indirect (free) bilirubin, presumably, is related to disturbance of capture by hepatocytes from blood.
The excretion of urobilinic bodies with feces and urine at mechanical jaundices is absent.
Слайд 71Differential diagnostics has a most practical value with:
cholestatic variant of
viral hepatitis,
mechanical jaundice as a result of compression of
bilious channels by tumor,
mechanical jaundice at biliary obstruction by stones or helmints.
Cholestatic variant of viral hepatitis :
mainly at VHB, but possible and at hepatitis C and other..
markers of viral hepatitis , recurrence of development, anamnesis.
observed for the people of any age.
pains are expressed mildly, localized in right hypochondrium, sometimes in epigastric area.
Слайд 72Tumor and cholelithiasis :
More often marked older 40 y.o.
Women
have a calculous cholecystitis mainly.
Disturbance of diet is sometimes
preceded appearance of obstruction jaundice.
There are signs of cholecystitis (pains in area of liver, jaundice and other) in anamnesis.
At tumor obstruction of bilious channels can be preceded chronic diseases of stomach, pancreas, loss of body mass, anemia and other - signs characteristic for tumor.
At obstruction of bilious channels by the stone pain attack after that an jaundice appears soon.
Pains have a characteristic irradiation in a right shoulder, shoulder-blade.
During a pain attack there can be nausea, vomiting, sometimes diarrea.
At tumor, pain can be very strong, but she develops gradually and progreses.
Слайд 73At all these states next also can be observed: Intensive
jaundice and itch of skin. Hemorragic syndrome.
A fever at VHB
is short-time and observed to development of jaundice.
At tumor at the start a temperature of body can be subfebrile (and even normal), but at progress of process disintegration of tumour tissue the temperature of body grows (often has large daily fluctuation).
At a calculose cholecystitis the temperature of body is also enhanceable, sometimes accepts septic character (fever of wrong type).
An anacholia is observed at all these illnesses.
Increase of liver of is observed at all examined illnesses.
At the mechanical jaundice conditioned by obstruction of bile ducts by a tumour or stone gall-bladder increases (symptom of Courvoisier’s).
gall-bladder is palpated as the large, tense painful rounded formation during obstruction of general bilious channel by the tumour of head of pancreas or tumour in area of papilla of duodenum.
Glucocorticoids reduce expressed jaundice at VHB, but not at the mechanical jaundices.
Слайд 74In blood for the patients of viral hepatitis leucopenia, ESR
normal, but at the subhepatic jaundices caused by a tumour
or stones more often leucocytosis and increase of ESR are found.
At the cholestatic variant of viral hepatitis activity of transferases is substantially enhanceable, moderate increase of ALKALINE PHOSPHATASE, thymol test positive, a cholesterol is decreased.
At tumor activity of transaminases is normal, ALKALINE PHOSPHATASE and cholesterol are aqutely enhanceable.
At biliary obstruction by a stone activity of ALKALINE PHOSPHATASE rises substantially, and sometimes activity of transferases rises short-timely, thymol test - negative, the cholesterol is mildly enhanceable or in a norm.
At viral hepatitis positive reaction on an urobilin is positive, while at the jaundices a reaction on an urobilin is negative.
Additional researches have an important value: USI. СT, X-ray, FGDS, laparoscopy.
Слайд 75Mechanical jaundice conditioned by helmints (opisthorchiasis, clonorchosis, schistosomiasis) :
jaundice is
moderate or slight,
the expressed pain attacks are absent,
epidemiology data
(endemic for these helminths districts),
eosinophilia(15-20% and more),
confirmed by finding out of helminths or its ova,
specific allergic and immunological reactions.
