Q

In acute haemorrhage, Why can O+ be given to men, but is generally avoided in women (need O-)

A

Women can become sensitised to the Rh, and can cause erythroblastosis fetalis. Rh mismatch for patients generally is ok though

When there is concern for massive transfusion requirements (eg, SBP

118
Why do pernicious anemia need periodic EGD
Risk of gastric CA
119
RF for upper extremity DVT. Name 5
Central venous cathete • Repetitive arm motions (eg, baseball pitching) • Weight lifting (increase scalene size causing thoracic outlet syndrome) • Malignancy thoracic outlet syndrome
120
Treatment of splenic sequestration crisis
Isotonic fluid resuscitation • Red blood cell transfusion • ‡ Splenectomy
121
SCD disease patient with: Abdominal pain • Palpable splenomegaly • Signs of anemia (tachycardia, pallor, fatigue) •Hypotensive shock 大
Splenic sequestration crisis
122
Tx of SCD induced stroke
• Exchange transfusion • Simple transfusion if exchange transfusion is unavailable
123
All patients with cryoglob, need which infx disease test
Therefore, all patients require hepatitis serologies (even if aminotransferases
124
General Tx for raynauds
Avoid aggravating factors CCB for persistent symptoms If secondary • Evaluate & treat underlying disorder • CB for persistent symptoms, aspirin for patients at risk for digital ulceration
125
Main symptoms difference between primary and secondary raynauds
Tissue injury or digital ulcers • Abnormal nail fold capillary examination In secondary
126
Recall muscles for shoulder abduction
Abduction of the shoulder is initiated by the Supraspinatus; O to 15° The Deltoid muscle can then abduct to 90°. Its the major abductor. 15° to 90° 180° (elevation) is brought about by rotation of the scapula upwards by the Trapezius and Serratus anterior.
127
HbCO levels in smokers and non smoker
Nonsmokers have low levels (<3%) of carboxyhemoglobin (due to normal enzymatic reactions). Cigarette smokers may have carboxyhemoglobin levels as high as 10%.
128
Why do we get polycythemia in CO toxicity
Carboxyhemoglobin shifts the oxygen dissociation curve to the left, impairing the ability of heme to unload oxygen at the tissue level. This results in tissue hypoxia. The kidney responds to tissue hypoxia by producing more erythropoietin (EPO). EPO stimulates the bone marrow to differentiate more red blood cells. Chronic CO toxicity is a cause of secondary polycythemia.
129
Leukamoid reaction vs CML regarding shift left
Leukamoid reaction: More mature (metamyelocytes > myelocytes) CML: Less mature (metamyelocytes < myelocytes)
130
Main issue with the G6PDH assay testing. How do we overcome this
It’s often normal during the attack. So in 3mo we do the confirmatory assay test
131
Clinical difference between Pyr Kinase def and G6PDH def
Unlike with G6PD deficiency, hemolysis is constant, so there is no relationship to inciting events (eg, sulfa drug exposure).
132
133
Leukoreduction of RBCs, two benefits
Leukoreduction reduces the risk of human leukocyte antigen alloimmunization and transmission of cytomegalovirus (which typically resides in leukocytes). Also reduces risk of FNHTR
134
First line Tx for chemo induced N/V
Serotonin (5HT) receptor antagonists (eg, ondansetron)
135
Thrombosis link to IV fluids
Limiting use of crystalloids (eg, $1 L), which dilute existing coagulation (eg, clotting) factors and platelets, thereby increasing coagulopathy
136
Iv fluids worsen the lethal triad. What is the lethal triad
"lethal triad" (hypothermia, acidosis, coagulopathy)
137
Mx for TRALI
Resp support only
138
TRALI vs TACO BP
Low and high resp
139
Risk factors for rectal sheath hematoma
Abdominal trauma, forceful abdominal contractions (eg, coughing) • Anticoagulation • Older age, female sex
140
How does a rectal sheath hematoma present
Acute-onset abdominal pain with palpable abdominal mass Worse pain on abdominal contraction (carnett sign) • Blood loss anemia, leukocytosis • ‡ Nausea, vomiting, fever
141
Why is a rectal sheath hematoma problematic below arcuate line?
The rectus sheath, which contains this muscle, does not extend posteriorly below the arcuate line; therefore, bleeding below this line (eg, lower aspect of rectus abdominis muscle) is relatively uncontained and can result in significant hemorrhage with hematoma formation.
142
Bone lesions in MM vs HyperPTH
Hyper PTH are typically well-defined (vs moth-eaten appearance of MM), and other radiographic abnormalities are common (eg, subperiosteal bone resorb the middle, phalanx,
143
Why do infants have a Hb nadir
After birth, increased oxygenation (ie, breathing, ductus closure) triggers reduced erythropoietin (EPO) production by the liver and kidney. Low levels of circulating EPO impair erythropoiesis in the bone marrow, which normally causes a mild, transient anemia that reaches a nadir of around 9-11 g/dL at age 2-3 months
144
Why do premats have a lower infant Hb nadir
htc is lower at birth, blood draws will also worsen it. Flora is less mature too
145
Pathophys of urticaria transfusion reaction
preformed recipient IgE antibodies reacting against a soluble allergen in the donated plasma, or vice versa (ie, donor IgE against recipient allergen).
146
Tx of metastasis to bone for the high calcium and bad pain?

151
Other than doing von Willebrand factor antigen test, What is another diagnostic test for von Willebrand’s disease
Ristocetin assay.
152
Interpret Ristocetin assay
If it improves the bleeding time this is indicative of Bernard Soulier disease. If it doesn’t improve bleeding time this indicates von Willebrand’s disease
153

VTE and no risk factor. First-degree relative had VTE test and 50 years old 1st° relative had thrombophilia
155
Diagnostic approach to HIT2. Consider beginning, initial diagnostic test, most accurate test
Obviously would do platelet count. The HIT PF4 Ab is first diagnostic test. Most accurate is the functional serotonin release assay
156
Why is testing for factor eight important in DIC
He is low in DIC, but is normal in liver disease
157
Antiphospholipid syndrome treatment.
Low molecular weight heparin bridge into warfarin. DOAC not so effective here
158
Recall of TTP management and HUS management
TTP - Plasma exchange, consider steroids and rituximab HUS – mainly supportive. Plasma exchange of severe. Dialysis if aKI. Hydration
159
ITP management. If platelets above 30, And no bleeding. Or if platelets less than 30 or bleed
No treatment as long as platelets above 30 and no bleeding. Corticosteroids or IVIg otherwise. Keep in mind this is for adults
160
Main difference in ITP management between adults and children
Adults we give treatment if platelets are less than 30 all the patients bleeding. In children we only give treatment if bleeding
161
If corticosteroids or IV immunoglobulin fails for ITP, what are the things could we do
Splenectomy, rituximab, TPO
162

164
PNH treatment. Consider best initial, alternative, definitive
Prednisone initially. Eculizumab is an alternative. Bone marrow transplant is definitive
165
Hereditary spherocytosis. Treatment. Consider most cases, and considered severe cases
Most cases just give folate supplementation and transfuse of need. Severe cases usually require splenectomy
166
First line treatment for warm autoimmune haemolytic anaemia. What about a mild. Potential second line
Corticosteroid First line. If mild no treatment. Splenectomy or IV Ig could be a second line
167
Is rituximab more for cold or warm autoimmune haemolytic anaemia

HU, phlebotomy when need, aspirin. Ruxolitinib is a jack inhibitor, and is the if HU is resistant. Less than 45%
170
Porphyria cutanea tarda management
Phlebotomy to remove porphyrin, avoid sun, hydroxychloroquine (like lupus)
171
Acute intermittent porphyria management
Mainly supportive, but hemin and glucose are good
172
HLH management
Dexamethasone and etopside. Consider antibiotics. Transfuse if needed
173
Treatment ideas for mastocytosis
Prevent degranulation. Antihistamine, cromylyn, anti-leukotriene
174
Neutropenic fever investigations. And treatment.
Investigation: chest x-ray, CT, blood culture, urine culture, stool culture, BUN, LFT. Give prophylactic Vanco and cephalosporin. No rectal exam. Antifungal cover if no improvement in 72 hours.
