Primary IgA nephropathy is believed to result from which immunopathogenetic mechanism?

1.Deposition of immune complexes containing IgA1 in mesangium with activation of alternative complement pathway

A 39year old man is complaining of the worst groin pain that he has ever experienced. He feels that he may have strained his groin playing football earlier in the week but notes that the pain seems to begin in the flank. It is affecting his left side and is colicky type and  the pain is worsening on urinating. Dipstick reveals microscopic haematuria. He has no past history of abdominal problems and has had no operations in the past. His observations reveal a heart rate of 120 beats/minute, respiratory rate 24 breaths/minute, sats 92%, blood pressure 157/91mmHg. What is the likely diagnosis?

A. Pyelonephritis
B. Renal calculus
C. Ureteric calculus
D. Renal cell carcinoma
E. Prostatism


The Correct Answer is C - Minimal change disease

Is a commonest cause of nephrotic syndrome in children in whom this disease occur frequently. Despite massive proteinuria, the renal function remains normal. Over 90% of patients are corticosteroid sensitive while small numbers of patients are corticosteroid dependent or resistant. The later can be treated by immunosuppressive agents. The disease is characterized by normal appearing glomeruli on light and immunofluorescence microscopy and the only abnormality detected is effacement of epithelial cell foot processes which is identified on electron microscopy only. No immune-complexes are identified and so the disease is not an immune complex in origin but several associated features suggests immune mediation. The current hypothesis is that the cell-mediated immunity seems to play an important role where T-lymphocytes are said to produce vascular permeability factor which is responsible for massive proteinuria.


The Correct Answer is A - IgA NEPHROPATHY

IgA NEPHROPATHY Causes: Nephrotic syndrome
Epidemiology/At risk individuals: Most common type of GN worldwide, occurs 1-2 days after URTI/GIT infections in patients

Clinical features: There is an acquired or genetic defect in regulating production of IgA antibodies. After URTI / GIT infection, too much IgA is produced a forms immune complexes and trapped in mesangium and activate alternate complement pathway a injury. Patient will develop Proteinuria + haematuria (Nephrotic syndrome). Progress to ESRF in 25-50% of patients.

Morphology: Light Microscope: mesangial proliferation, matrix deposition. Immunofluorecence: IgA in mesangium + C3.


The Correct Answer is C - Ureteric calculus

Pyelonephritis is an ascending urinary tract infection that has reached pelvis of thekidney.It primarily affects the interstitial area and the renal pelvis or, less often, the renal tubules. Chronic pyelonephritis is persistent kidney inflammation that can scar the kidneys and may lead to chronic renal failure.
Papillary necrosis is complication of pyelonephritis.
Kidney stones formation or urolithiasis is comprised of calcium carbonate crystals in the presence of hypercalciuria and a common complication is chronic pyelonephritis.


Correct answer is B
Fanconi syndrome is a generalized disorder of the Proximal Tubules. The defect can lead to glycosuria, aminoaciduria, phosphaturia, bicarbonaturia and excessive urinary loss of K+, Na+, Ca++, Mg++, uric acid and other organic acids.It may be inherited, or caused by drugs or heavy metals.

Correct Answer - T T T T T

  • In dark Environment
  • Strong sexual arousal
  • Oxytocin
  • Oculomotor nerve palsy
  • Head injury or orbit trauma (eye injury),or any iris trauma including Surgery
  • Anticholinergics such as atropine
  • Cycloplegics(agents that paralysis of the ciliary muscle of the eye) are also mydriatic(an agent that induces dilation of the pupil)- cyclopentolate,tropicamide
  • Cocaine - inhibits the normal reuptake of norepinephrine into presynaptic nerve terminals resulting in an increased level of extracellular norepinephrine. The released norepinephrine then proceeds to bind to adrenergic receptors,and the end result is dilation of the pupil
  • Drugs that increase serotonin levels - fenfluramine, antidepressants such as the SSRIs and MAOIs
  • Adie's pupil - benign condition affecting the young women
  • Migraine

Correct Answer - F F T T F

A chronic subdural hematoma (SDH) is an old clot of blood on the surface of the brain beneath its outer covering. It predominantly occursin infancy and in the elderly. 1/6th of cases are bilateral.
Predisposing factors
Less than 50% might have a traumatic event
Other risk factors include alcohol abuse, seizures, shunts that drain excess cerebrospinal
fluid from the brain,brain atrophy,blood thinning medications such as Coumadin and coagulation disorders

The symptoms of a chronic subdural haematoma do not usually appear until about 2-3 weeks
after the initial head injury (in some people it may be months)
The symptoms tend to progress gradually
The most common complaint is headache, seen in up to 80 percent of patients. Other symptoms
include lethargy, memory impairment, confusion, weakness, nausea, vomiting, impaired vision
and seizures
Patients with large hematomas may develop varying degrees of paralysis and coma
Papilloedema is uncommon

If there is a small,subdural haematoma that is not producing any symptoms,it can sometimes be treated just by careful monitoring and observation. The blood clot is left to re-absorb by itself

MCQ 01 Correct Answer - T T T T F
Physiology of pregnacy psecentation

Renal blood flow increases by about 25 % from 1.2 to 1.5 litres perminute.This occurs early in pregnancy. Changes in renal functionroughly parallel those in cardiac function. GFR increases 30 to 50%,peaks between 16 and 24 wk gestation, and remains at that level until
nearly term, when it may decrease slightly because uterine pressure onthe vena cava often causes venous stasis in the lower extremities.Renal plasma flow increases in proportion to GFR. As a result, BUNdecreases, usually to less than 10 mg/dL (less than 3.6 mmol urea/L), and creatinine levels decrease proportionally to 0.5 to 0.7 mg/dL (44 to 62 ╬╝mol/L). Marked dilation of the ureters (hydroureter) is caused by hormonal influences (predominantly progesterone) and by backup due to pressure from the enlarged uterus on the ureters, which can also cause hydronephrosis. Postpartum, the urinary collecting system may take as long as 12 wk to return to normal. Glucose transfers in bulk through the glomerulus and is then reabsorbed by the proximal tubule.With the increased GFR, much more sugar is dumped on the tubule and may swamp its reabsorptive capacity. The result is the common pregnancy finding of glycosuria in the presence of normal blood glucose levels.

MCQ 02 Correct Answer - T T T F T
Shoulder dystocia presentation

Shoulder dystocia occurs in approximately 1% of vaginal births.There are well-recognised risk factors, such as diabetes, fetal macrosomia, and maternal obesity. Premature labour means small babies and a reduced risk. Mid-cavity forceps suggests some difficulty in descent of the head. Zavanelli's maneuver, which involves pushing the fetal head back in with performing a cesarean section is one way of managing Shoulder Dystocia. MCQ 03
