Question 3

INT - 13.3
You take care for a patient with deep vein thrombosis, which occured also previously too. Baseline aPTT prolonged with 12 seconds, which can not be corrected with addition of normal plasma. The most likely diagnosis:

A) dysfibrinogenaemia

B) lupus-anticoagulant/antiphospholipid syndrome

C) F XIII deficiency

D) antithrombin deficiency

Answer 3

ANSWER
B) lupus-anticoagulant/antiphospholipid syndrome

EXPLANATION
Dysfibrinogenaemia rarely cause thrombosis, if so mostly venous. Antithrombin deficiency does not typically provoke stroke, orherwise normal pasma can correct coagulation test results. In antiphospholipid lupus anticoagulant syndrome one might not achieve aPTT correction by mixing patient plasma with normal.

A) If thrombocytopenia severe, spontaneous improvement is uncommon.

B) Spontaneous recovery is the most common.

C) Improvement might be achieved only with 1 mg/kg prednisone.

Answer 15

ANSWER
B) Spontaneous recovery is the most common.

EXPLANATION
The correct selection is B, as childhood acute ITP spontaneously and quickly cures in vast majoritiy of cases, without any intervention.

Question 16

INT - 13.17
In chronic ITP (non post infectious event) the prognosis

A) Spontaneous remissions are the rule

B) Spontaneous remissions are uncommon, but after a short course of 1 mg/kg Prednisolon 80% achieves durable remissions

C) In chronic ITP spontaneous remissions are uncommon, first line 1 mg/kg Prednisolon achieves durable remissions in 10-15%

D) Any kind of remisssion needs combined immusuppressive therapy

Answer 16

ANSWER
C) In chronic ITP spontaneous remissions are uncommon, first line 1 mg/kg Prednisolon achieves durable remissions in 10-15%

EXPLANATION
C is correct, as in adultory ITP sponatenous cure is extremely rare. Point B is incorrect, as steroid therapy much less rarely results in longstanding remission in chronic ITP. Selection D is clearly incorrect, you do not neeed combined immunsuppression in ITP, as steroids, high dose invenous immunoglobulins, or is some cases Anti D sera might achieve remission, even if short duration.

Question 17

INT - 13.18
Please identify the antidote of unfractionated (Na) heparin.

A) Vitamin K 20 mg iv.

Answer 45

ANSWER B) 2nd, 3rd and 5th answers are correct EXPLANATION In acute DIC aPTT is prolonged due to factor consumption, while unfractionatd heparin does it by antithrombin anti Xa activities. In lupus anticoagulat (antiphospholipid syndrome aPTT is prolonged in vitro (complexes are blocking catalytic surfaces to the reaction) whereas in vivo more thrombotic even might develop. LMWHS does not really prolong aPTT, due their specific anti Xa actity, aPTT is also not modified either by Leiden mutation or or antiplatelet durg ticlopidin

Question 46

INT - 13.51 Typical findings in hemolysis: 1) direct bilirubin elevated 2) indirect bilirubin elevated 3) ubg reaction increased in urine 4) bilirubin positivity in urine 5) high reticulocyte count 6) low reticulocyte count A) 1st and 4th answers are correct B) 4th and 6th answers are correct C) 1st, 4th and 6th answers are correct D) 2nd, 3rd and 5th answers are correct

Answer 46

ANSWER D) 2nd, 3rd and 5th answers are correct EXPLANATION Correct responses are 2,3,5. In hemolysis indirect bilirubin released to circulation and not excreted via kidneys. This also results in more direct bilirubin excretion into the intestine, where it is transformed to urobilinogen, which recirculates, and more urobilinogen will appear in the urine. Due to marrow compensatory activity, more red blood cells will be produced, resulting in elevated reticulocyte counts. Correct selection 2,3,5

Question 47

Question 63

INT - 13.73 Which is the most likely disease? A 16 years old girl admitted to your ward, looks really sick. History: no meaningful previous event, she had regular sport activity, but 8 days ago she had transient mild fever and diarrhoea for 2 days. Last day she had fever again, headache, dizziness, mild confusion, she could not even recognise her sister. Small petechiae and suffusiones appeared. You observe somnolence, mild jaundice. No meningeal signs. Liver, spleen, lymphnodes are normal sized. Platelet count 10 G/L, WBC 15 G/L, urea 11 mmol/l, hemostasis screening tests are normal. A) acute myeloid leukemia B) acute lymphoid leukemia C) acute immun thrombocytopenic purpura (ITP) D) Thrombotic mikroangiopathia, HUS (hemolytic uremic syndrome) E) acute víral hepatitis F) acute DIC

Answer 63

ANSWER D) Thrombotic mikroangiopathia, HUS (hemolytic uremic syndrome) EXPLANATION Acute myeloid or lymphoid leukemias are not typically associated with cognitive dysfunctions or previous diarrhoea episodes. In acute viral hepatitis platelet counts are usually normal. Confusion is very rare in acute DIC early stage, and there are severe bleedings along with laboratory signs of consumption coagulopathy. This clinical presentation presentation is typical to thrombotic microangiopathy HUS or TTP. So correct answer is D.

Question 64

INT - 13.74 Which are the most appropriate examination in this case to prove suggested diagnosis A 16 years old girl admitted to your ward, looks really sick. History: no meaningful previous event, she had regular sport activity, but 8 days ago she had transient mild fever and diarrhoea for 2 days. Last day she had fever again, headache, dizziness, mild confusion, she could not even recognise her sister. Small petechiae and suffusiones appeared. You observe somnolence, mild jaundice. No meningeal signs. Liver, spleen, lymphnodes are normal sized. Platelet count 10 G/L, WBC 15 G/L, urea 11 mmol/l, hemostasis screening tests are normal. 1) Bone marrow – myeloblast accumulation 2) Bone marrow – lymphoblast accumulation 3) Bone marrow – accumulation 4) GOT-/GPT 5) HbsAg screening 6) LDH-activity 7) peripheral blood smear, leukocytosis analysis 8) peripheral blood smear, lymphoblast search 9) peripheral blood smear, fragmentocyte (fragmented sred blood cells) screen 10) Platelet surface immunglobulin detection 11) kidney function analysis A) 1st, 4th and 11th answers are correct B) 2nd, 5th and 10th answers are correct C) 6th, 9th and 11th answers are correct D) 7th, 8th and 10th answers are correct

Answer 64

ANSWER C) 6th, 9th and 11th answers are correct EXPLANATION In HUS one may find excessive number of bone marrow megakaryocytes (same as in some other conditions, i.e. ITP) so this examination is not really indicated. Elevated LDH, Fragmented red blood cells in peripheral blood smears, modest renal impairment should be searched and detected as simple but important diagnostic tools. So correct is 6, 9, 11. all the other tests are useless in confirming your diagnosis.

Question 65

INT - 13.75 Which are the most useful disease specific diagnostic tools A 16 years old girl admitted to your ward, looks really sick. History: no meaningful previous event, she had regular sport activity, but 8 days ago she had transient mild fever and diarrhoea for 2 days. Last day she had fever again, headache, dizziness, mild confusion, she could not even recognise her sister. Small petechiae and suffusiones appeared. You observe somnolence, mild jaundice. No meningeal signs. Liver, spleen, lymphnodes are normal sized. Platelet count 10 G/L, WBC 15 G/L, urea 11 mmol/l, hemostasis screening tests are normal. 1) Bone marrrow myeloblast flow cytometry 2) t15,17 translocation, suggesting acute promyelocytic leukemia, to indicate retinooid therapy 3) Durable increment of platelet counts after platelet transfusion, a sin ITP foreign platelets are not affected by antibodies 4) test if patient plasma provokes platelet aggregation in control specimen 5) verotoxin ELISA 6) ADAM TS13 activity or complementactivation measurement 7) TFPI measurement (tissue Factor inhibitor) A) 1st and 7th answers are correct B) 5th and 6th answers are correct C) 3rd and 7th answers are correct D) 4th and 5th answers are correct E) all of the answers are correct

Answer 65

ANSWER B) 5th and 6th answers are correct EXPLANATION HUS plasma might provoke healthy platelet clumping phenomenon, but this is uncertain and not used as specific test. Verotoxin ELISA seemes to be important in post diarrhoea HUS cases. More recently we understood that the most common background is ADAMTS13 abnormality, and there are cases with complement system abnormality. All other options are irrelevant. So the correct selection is 5, 6.

Question 66

INT - 13.76 Which therapeutic approach is the most appropriate A 16 years old girl admitted to your ward, looks really sick. History: no meaningful previous event, she had regular sport activity, but 8 days ago she had transient mild fever and diarrhoea for 2 days.

Answer 72

ANSWER B) Platelet transfusion EXPLANATION Platelet transfusion may severely worsen TTP/HUS clinical signs, so it it strictly contraindicated. All other options are rather neutral. Correct B

Question 73

INT - 13.83 What is the most likely diagnosis suspected? You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. A) lymphogranulomatosis B) chronic lymphoid leukemia C) acute lymphoid leukemia D) chronic myeloid leukemia E) mononucleosis infectiosa

Answer 73

ANSWER B) chronic lymphoid leukemia EXPLANATION The clinical presentation is a typical case of chronic lymphocytic leukemia (CLL). Characteristic is advanced age, lymphocytosis with seemingly matured small lymphocytes, lymphadenopathy, modest anemia somtimes mild spleen enlargement. So correct is B. In Hodgkin you do not see lymphocytosis or low immunoglobulins. Mononucleosis is the disease of young people. In chronic myeloid leukemia granulocyte cell line accumulation might be observed. In acute lymphoid leukemia lymphoblasts are seen.

Question 74

INT - 13.84 What are the most helpful diagnostic tools in this case You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. 1) lymph node biopsy 2) Gumprecht shadows in peripheral blood smears 3) Bone marrow examination 4) citogenetics screening for Philadelphia-chromosome 5) peripheral blood flowcytometry.

The appearance of 5 G/L or more CD19/CD5 coexpressed lymphocytes in peripheral blood is the official diagnostic criterium, Gumprecht shadows are additional markers (but not enough in itself). Paul Bunnel and Philadelphia are used in mononucleosis and CML. You do not need lymph node or bone marrrow biopsy to approve your diagnosis.

Question 75

INT - 13.85 What diagnostic tool is the most useful in this condition to define prognosis You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. A) Epstein–Barr-víral serology B) Epstein–Barr-vírus genomic analysis in malignant cells C) Bcr-Abl rearrangement analysis, even if cytogenetics are negative D) Philadelphia chomosome detection E) PAS and acid phosphatase citochemistry F) peripheral blood FISH analysis

Answer 75

ANSWER F) peripheral blood FISH analysis EXPLANATION Correct selection is F, as FISH information are important factors in prognosis and progression of disease. All the others are not related to CLL.

Question 76

INT - 13.86 What clinical signs, complications you should check and foresee for longer period You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. 1) slowly progressing lymphadenomegaly 2) splenic rupture 3) hepatitis like symptoms 4) myocarditis like symptoms 5) increased likelyhood of infections 6) transformation into accelerated or blastic phase 7) transformation into myelofibrosis 8) After the cure of lymphogranulomatosis secondary cancer might develop A) 2nd and 4th answers are correct B) 6th and 7th answers are correct C) 3rd and 8th answers are correct D) 1st and 5th answers are correct

Answer 76

ANSWER D) 1st and 5th answers are correct EXPLANATION Slowly progressive lymphadenopathy and increased frequency of infections are the most common characteristics to CLL, so correct is D. Blast transformation occurrs in CML. option 8 might be valid only for Hodgkin patient.

Question 77

INT - 13.87 How much is the average survival of the disease while treating? You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. A) spontaneous cure in all B) One or two years in spite of therapeutic efforts C) Four years chronic phase, followed by one year accelerated phase D) Fove year survival is 55–60% in Hodgkin lymphoma E) 8–15 average survivial, however final cure can be achieved even with modern therapies

Answer 77

ANSWER E) 8–15 average survivial, however final cure can be achieved even with modern therapies EXPLANATION In most CLL cases E is the good selection, survival is long but CLL for the time being is still incurable condition. C is valis for CML, D would be lymphogranulomatosis, but survival is not even correctly given for this disease.

Question 78

INT - 13.88 Which alteration carries important prognostic relevance You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. 1) histological subtype, as lymphoid depletion cases run poor prognosis 2) In ALL Philadelphia chromosome means very bad prognosis 3) lymphocyte doubling time shorter than 6 month 4) anemia, thrombocytopenia, medullary infiltration 5) male sex in itself has worse prognosis in Hodgkin 6) In chronic lymphocytic leukemia FISH p53 positivity especaillay bad prognosis A) 1st and 3rd answers are correct B) 3rd and 6th answers are correct C) 4th and 6th answers are correct

Answer 78

ANSWER B) 3rd and 6th answers are correct EXPLANATION B is the good selection, as short cell doubling time or FISH p53 positivity indicates progression or poor prognosis.

Question 79

INT - 13.89 What is the adequate therapy in this case? You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. A) hydroxyurea first line, may consider interferons which might induce cytogenetic response of Phildelphia abnormality B) ALL-standard agents: antracyclin, steroid, vincristine, methotrexate polychemotherapy C) in mononucleosis observation is enough without any intervention mononucleosis D) COPP (cyclophosphamide + vincristine + procarbazin + prednisolone) protocoll, 6 cycles E) watch and wait, if progression (quick doubling of white blood cell count, gross lymphadenopathy, B signs) first line should be Fludarabine-Cyclophosphamid-MabThera immunchemotherapy, in elderly, moderately frail patients MabThera+bendamustin

Answer 79

ANSWER E) watch and wait, if progression (quick doubling of white blood cell count, gross lymphadenopathy, B signs) first line should be Fludarabine-Cyclophosphamid-MabThera immunchemotherapy, in elderly, moderately frail patients MabThera+bendamustin EXPLANATION Watch and wait is the best approach in early CLL, therapy is indicated only if cell doubling is shorter than 6 month, lymph node enlargement is quick, progressive or there are B signs. So correct selection is E. All other options are irrelevant in CLL.

Question 80

INT - 13.90 Which 3 alteration may help the most during followup You see a 62 years old male, with cherry sized neck, axillary, inguinal painless lymphadenopathy. Moderate weakness and weightloss. He had some mild fever and upper airway infections recently. Spleen enlarged by 6 cm. White Blood cell count 23 G/L, 76% small matured lymphocyte, other forms are normal. Hemoglobin 105 g/l, platelet count normal. Reduced IgG. 1) extent of splenomegaly 2) extent and progression of lymphadenomegalia 3) kinetics of white blood cell count increase 4) immunglobulin levels 5) progression of FISH alterations 6) EBV-antibody -titer changes 7) serum-copper levels A) 1st, 5th and 7th answers are correct B) 5th, 6th and 7th answers are correct C) 2nd, 3rd and 5th answers are correct D) 1st and 5th answers are correct E) all of the answers are correct

Answer 80

ANSWER C) 2nd, 3rd and 5th answers are correct EXPLANATION CLL progression markers are 2,3, and 5. Cell number kinetics, quick progression of lymphadenopathy are clear indicators, while bad baseline FISH markers, or secondary FISH alterations are informing you about prognosis or even worse prognosis. EBV markers and copper levels are useless in CLL:

Question 81

INT - 13.91 What other examinations should should be performed before starting anticoagulant therapy? A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in he right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. 1) Iv. phlebography, as all types of anticoagulants are extremely dangerous during pregnancy, to ascertain more your diagnosis 2) aPTT 3) fibrinogen level 4) Factor VIII. activity 5) baseline platelet count 6) Bleeding time measurememnt A) 1st and 3rd answers are correct B) 2nd and 5th answers are correct C) 4th and 6th answers are correct D) 1st and 5th answers are correct E) all of the answers are correct

Answer 81

ANSWER B) 2nd and 5th answers are correct EXPLANATION Baseline haemostasis screening is indicated to identify potential thrombophilia (e.g. lupus anticoagulant), but more importantly baseline platelet count is necessary to see whether heparin induced thrombocytopenia develops or not. Good selection 2 and 5. Phlebography is not indicated, as invasive and does not provide more information than Color Doppler, which is the gold standard in deep vein thrombosis diagnostics, and you should not expose a pregnant woman to unnecessary radiation. Fibrinogen level and FVIII activity does not carry any importance in this case. Bleeding time is not altered by deep vein thrombosis

Question 82

INT - 13.92 Which anticoagulant is that does not cross placental barrier and can be administered safely during pregnancy? A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in he right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. A) low molecular weight heparin B) coumarol derivatives C) dabigatran D) rivaroxaban

Answer 82

ANSWER A) low molecular weight heparin EXPLANATION Low molecular weight heparins (LMWH) do not cross placenta, they might be given during pregnancy without any harm to the fetus or mother. Correct A.

Question 83

INT - 13.93 Wich anthrombotic therapy should be selected in this case? A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in he right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. A) only aspirin can be applied in pregnancy B) Low molecular weight heparin, therapeutic dose C) couumarin, as all heparins are contraindicated in pregnant patients D) thrombolytic treatment E) surgical thrombectomy

Answer 83

ANSWER B) Low molecular weight heparin, therapeutic dose EXPLANATION Correct is B. LMWH may be administered for thrombotic or thrombophiliac pregnants. coumarols should be avoided, being teratogenic. thrombolytic treatment if possible should not be used during pregnancy (placental damage). In this case thrombolytic approach is not indicated. Surgical thrombectomy does not seems necessary, as well. Aspirin is not a convenient agent for venous thrombos

Question 84

INT - 13.94 Considering all this, what are the feasible options A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in the right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in the right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. 1) aspirin 2) aspirin + coumarol 3) Unfractionated-heparin 1000–1200 U/hour, infusion 4) immobilisation, elastic bandage on the thrombotic leg 5) Low molecular weight heparin twice/day 100–120 U/kg subcutaneously. 6) streptokinase or tissue plasminogen activator 7) pentoxyphyllin A) 1st and 3rd answers are correct B) 2nd and 7th answers are correct C) 4th and 5th answers are correct D) 3rd and 5th answers are correct E) all of the answers are correct

Answer 84

ANSWER C) 4th and 5th answers are correct EXPLANATION Good answers 4 and 5, the LMWH doses are in concert with clinical practice

Question 85

INT - 13.95 Identify the most dangerous complication of your therapy: A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in he right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. A) erosion, gastric bleeding B) heparin induced thrombocytopenia C) coumarol-necrosis D) hypofibrinogenemia

Answer 85

ANSWER B) heparin induced thrombocytopenia EXPLANATION By far the most dangerous side effect is heparin induced thrombocytopenia. Gastric erosions in this setting has no clinical impact. Hypofibrinogenemia is not induced by LMWHs. Coumarol necrosis of course irrelevant

Question 86

INT - 13.96 After the acute thrombotic period which type of anticoagulant prophylaxis should be applied in this case? A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in he right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. 1) Coumarols 2) aspirin 3) Low molecular weight heparin profilactic dose once daily 1 4) elastic bandage 5) prophilaxis is not necessary 6) prohylaxis is dangerous in pregnancy, so not recommended A) 1st and 3rd answers are correct B) 3rd and 4th answers are correct C) 5th and 6th answers are correct D) 3rd and 5th answers are correct E) all of the answers are correct

Answer 86

ANSWER B) 3rd and 4th answers are correct EXPLANATION Elastic bandage on the leg along with once daily LMWH is the convenient thrombosis prophylasis during pregnancy. Correct 3 and 4. Coumarol is teratogenic. Aspirin is not able to prevent venous thrombosis. prophylaxis is really necessary and the described form is not dangerous during pregnancy.

Question 87

INT - 13.97 In her case suspicion of thrombophilic condition shoud be an issue. What is the most like hereditary thrombophilia based on statistics? A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in he right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. A) antithrombin deficiency B) protein C deficiency C) activated protein C resistance/F. V. Leiden-mutation D) protein S deficiency E) homozygous hyperhomocysteinemia

Answer 87

ANSWER C) activated protein C resistance/F. V. Leiden-mutation EXPLANATION The most frequent hereditary thrombophilia in Europe is Leiden mutation, correct is C.

Question 88

INT - 13.98 So the most common thrombophilia was proved. What prophylactic guideline is recommended in her case? A 26-year-old pregnant lady in 16 weeks of pregnancy arrives to your office. Progressive swelling and pain developed in he right femoral region, four days ago. Pregnancy goes on normally otherwise. Doppler ultrasound reveals newly developed deep vein thrombosis in right femoral vein and popliteal vein. The patient's mother and sister also had thrombotic episodes. A) all cases whoi had once DVT lifelong anticoagulant prophylactic approach recommended. B) All cases with previous DVT should receive couple of years anticoagulant prophylaxis, after some years may go for cautious dose reduction C) In all such cases a 6 mont prophylaxis is enough D) As all prophylactic efforts are ineffective, their use is not recommended

Answer 88

ANSWER B) All cases with previous DVT should receive couple of years anticoagulant prophylaxis, after some years may go for cautious dose reduction EXPLANATION The guidelines indicate anticoagulant prophylaxis in Leiden mutation after the first thrombotic event. Thrombosis free Leiden mutants should not receive that. After a thrombotic event with Leiden mutation anticoagulant prophylaxis is indicated for some years, maybe with tapering dose later on.
