-Howell-Jolly bodies are seen in hyposplenism and pencil cells are a feature of iron-deficiency. Both of these are seen in coeliac disease.

-Glucagon is the main antidote in patients with beta blocker overdose with significant hypotension and bradycardia.

4-10 mg bolus then 2-5 mg / hour iv infusion.

#Cardiology

-Bicuspide aortic valve is the most common congenital cardiac anomaly in turner's syndrome 16%.


#Cardiology

-ACE-inhibitors and beta-blockers have NO effect on mortality in heart failure with preserved ejection fraction.

#Cardiology

Cough (acute): antimicrobial prescribing.

#Respiratory

-Avoid co-administering RAAS inhibitors and NSAIDs in patients with reduced renal perfusion (e.g., in congestive heart failure, renal artery stenosis) because doing so can significantly decrease their GFR.

#Nephrology

-AKI management is primarily supportive. Currently, there are no specific pharmacotherapies for AKI.

#Nephrology

Howship-Romberg Sign

◼️Pain radiating down the medial thigh to the knee due to
compression of obturator nerve (anterior division) by the hernial sac.

◼️Charactaristic of an incarcerated hernia.

◼️Present in 25-50% cases.

#Hernia

-On a native valve ,the most common organisms causing infective endocarditis is Streptococcus viridanse.

#Cardiology

Some findings give important clues to the chronicity of disease:

Examples:

♥️ LVH on ECG suggests HTN has been longstanding.

🫘 A thin, echogenic renal cortex on US suggests CKD rather than AKI.

🩸Anemia w/ low MCHC suggests longstanding Fe deficiency.

#Medicine

Main treatment of:

-Good pasture syndrome👉🏼Plasmapheresis.

-Churgstrauss or Wegner granulomatosis or PAN👉🏼 High dose steroids and cyclophosphamide .

-Minimal change disease👉🏼 Oral steroids.

-Scleroderma or diabetic associated nephropathy ( to slow progression )👉🏼ACEI .

#Medicine

-Presence of Anti-SSA/Ro in pregnant women with SLE is associated with an increased risk of [congenital heart block in the fetus].


#Rheumatology

Remember:

-In prosthetic valves Staphylococcus aureus & Staphylococcus Epidermidis are the most common causes of endocarditis. But MRS are rare causes.

#Cardiology

-Gastric linitis plastica is a diffuse type of cancer (3-19%of adenoca)in which the cells invade throughout the stomach, resulting in the thickening and rigidity of the stomach wall.
