02) Acid base balance
Refer 16th edition Harrison Vol 1 page no 263-270

AG = Na – (Cl + HCO3) –Normal = 10-12 mmol/L

Causes of high Anion Gap Metabolic acidosis (Table 42.3)
• Lactic Acidosis
• Keto Acidosis – DM /starvation/alcoholic
• Toxins –Ethylene Glycol, Methanol, Salicylates
• Renal Failure(A/C & C/C)

Causes of Non anion Gap Acidosis (Table 42.4)
• Gastrointestinal bicarbonate loss – Diarrhea, External Pancreatic or small bowel drainage, Uretrosigmoidostomy ,Drugs – Calcium chloride, Magnesium sulphate,Colestyramine.
• Renal Acidosis – *Hypokalemia – a . Proximal(Type2)RTA b. Distal(Type1)RTA *Hyperkalemia – generalized distal nephron dysfunction(type4RTA)
• Drug induced Hyperkalemia – Potassium sparing diuretics, Trimethoprim, Pentamidine, ACE inhibitors, NSAIDs, Cyclosporine.
• Other – Acid loads, Loss of potential bicarbonate, Expansion acidosis, Hippurate, Cation exchange resins.

Treatment of severe Acidosis (Metabolic)
Severe acidosis (pH<7.20) warrants iv administration of 50-100meq of NaHCO3

Treatment of Lactic Acidosis
Then underlying condition that disrupts lactate metabolism must first be corrected: tissue perfusion must be restored when it is adequate.

>17mmol/L accompanied with Hyperglycemia

• Pain usually appears gradually over a few hours before peak intensity is reached – Usually Dull & Boring with superimposed ice pick like lancinating pains.
• Scalp tenderness – present
• Head ache – worse at night & is often aggravated by exposure to cold
• ESR – is often, though not always: elevated

Tension Head Ache
• Chronic head pain syndrome characterized by a bilateral tight, band like discomfort.
• Pain typically builds up slowly, fluctuates in severity & may persist more or less continuously for many days.
• Exertion does not worsen the head ache.
• Episodic/Chronic headache

• De-Activators – Sleep , pregnancy, Exhilaration, triptans.


Cluster Head ache
( Raeders syndrome, Histamine cephalagia , sphenopalatine neuralgia)
• Usually episodic
• Men affected 7-8 times often than women
• 1-3 short lived attacks of Periorbital pain per day over a 4 to 8 week period, followed by a pain free interval that averages 1 year
• Peri-orbital or less commonly,temporal pain begins without warning & reaches a crescendo within 5 min.
• Pain is usually excruciating in intensity and is deep non fluctuating and explosive in quality
• Pain is strictly unilateral & usually affects the same sides in subsequent months
• Attacks last from 30min to 2 hours
• Associated symptoms – Homolateral Lacrimation, Reddening of the eye, Nasal stuffiness, Lid ptosis & nausea
• Alcohol provokes attack in 70% patients

• Onset is nocturnal in 50% cases which awkens the patients within 2 hours of falling asleep.

05) Intracranial Haemorrhage
(Ref: 16th edition Harrison vol 2 page no 2387)

• MCC of SAH = Head trauma
• 2nd MCC of SAH = Saccular aneurysym
• Saccular Aneurysm rupture is preceded by a brief moment of excruciating head ache
• 45% cases severe head ache is associated with exertion.
• Most common type of intracranial hemorrhage = Intra parenchymal hemorrhage
• Hypertensive intra parenchymal hemorrhage usually results from spontaneous rupture of a small penetrating artery deep in the brain.
• Most common sites are Basal Ganglia, Deep cerebellum & Pons

06) Hyperparathyroidism
(Ref: 16th edition Harrison vol 2 page no 2252)

• Hypercalcaemia causes – Fatigue, depression, Mental confusion, Anorexia, Nausea, Vomiting, Constipation, Short QT interval

(Ref: 16th edition Harrison vol 2 page no 1415)

• Narrow pulse pressure
• Hypotension
• Elevation of JVP
• Prominent X descent & diminutive or absent Y descent

(Ref: 16th edition Harrison vol 2 page no 1410)

• Asymmetric left ventricular hypertrophy often with preferential hypertrophy of the inter ventricular septum
• Dynamic left ventricular outflow tract pressure gradient
• SAM(Systolic Anterior Movement) of the Mitral valve

• Conditions aggravating murmur of HOCM ==>A)Which increase myocardial contractility- Exercise, Sympathomimetic amines, Digitalis Glycosides
==> B)Which reduce ventricular volume – Valsalva maneuver, Sudden standing, Nitroglycerin, Amyl nitrite, Tachycardia

? Conditions ameliorating the murmur ==> Phenylephrine, Squatting, Sustained hand

• The association of thymoma and hypogammaglobulinaemia usually occurs in late adult life.
• Bacterial infections and sever diarrhea reflect the antibody deficiency
• Fungal and viral infections are infrequent complications
