Remember:

-Monospot test has a specificity of85% & a sensitivity of 100% for diagnosis of infectious mononucleosis.

#Infections

Endocrine Causes DM:

-Cushing syndrome
-Hyperthyroidism
-Acromegaly
-Pheochromocytoma
-Glucagonoma.

#Endocrine

LATRAL MEDULLARY SYNDROME :

Cerebellar signs, contralateral sensory loss & ipsilateral Horner's
Lateral medullary syndrome, also known as Wallenberg's syndrome, occurs following occlusion of the posterior inferior cerebellar artery PICA.

-Cerebellar features:
ataxia
nystagmus

-Brainstem features:
ipsilateral: dysphagia, facial numbness, cranial nerve palsy e.g. Horner's
contralateral: limb sensory loss.

#Neurology

THE LEADING CAUSE OF PNEUMONIA IN HIV Patients IS Pneumocystis jeroviciie p.
But the most common is S.pneumoniae.

#Respiratory

CVS MORTALITY PREDICTORS IN MVP:

-Moderate to sever MR
-EF is less than50%
-Left aterial size greater than 40mm.
-Flial leaflets
-Aterial fibrillation
-Age older than 50 years.

#Cardiology

Acute hemolytic transfusion reaction (AHTR)

-It is anadverse reaction to blood transfusion that occurs within the first 24 hours after transfusion.


-It's intravascular hemolysis; type II hypersensitivity reaction.

-Rapid onset during transfusion (because of preformed antibodies) or up to 24 hours after thetransfusion

Symptoms include: 
Fever "first" chills, nausea, flushing
Hypotension, tachycardia
Flank pain
Dyspnea, tachypnea
Hemoglobinuria (due to intravascular hemolysis)
Jaundice (due to intravascular hemolysis).

#Blood

•What will you find in ECG in case of Meningitis?

-There may be sinus bradycardia "increase RR interval".
Due to cushing response in advanced case.

#Neurology

Remember

-The most common malignant tumors of bone are plasma cell tumors related to multiple myeloma.

#Rheumatology

-The triad of portal vein thrombosis, hemolysis, and pancytopenia suggests Paroxysmal nocturnal hemoglobinuria (PNH).

#Blood

-Enteroviruses (especially coxsacie viruses and echoviruses) are the most common cause of all types of meningitis in all patient groups.

-S.pneumoniae is the most common bacteria causing meningitis in adults.


#Neurology

Remember:

In AS:
-Exertional dyspnea, angina pectoris and syncope are the three cardinal symptoms in patients
with pure or predominant AS.

#Cardiology

-Drugs are the most common cause of thrombocytopenia.

#Blood

-Cryoprecipitate is a source of fibrinogen, factor VIII & von Willebrand factor (vWF).

#Blood

-FFP contains stable coagulation factors and plasma proteins like fibrinogen, antithrombin, albumin, and proteins C and S.

#Blood

-JAK2 gene is located on the short arm of chromosome 9.

#Blood

•JAK2 mutations are associated with:

-Polycythemia vera,
-Essential thrombocythemia,
-Primary myelofibrosis.

Remember:

-During the last two trimesters of pregnancy, daily iron requirements increase to 5 - 6 mg/day.
