Case Discussion

56 year male , ex smoker with significant history of Ischemic heart disease

Presented in emergency with the complaint of Generalized weakness, Short

Of breath and decreased urine output for last 2 weeks.

He was already investigated outside in cardiology services which he often

Visisted for his chronic heart ailment. His serum creatinine jumped from 0.7

Mg/dl to 4.1 mg/dl in 1 week period.

His past history entails stent placement 8 year back after angiography. Since  then

He was on heart medication including anti hypertensive agent s whose is prescription

Was not brought by him and he does not  know the names for all medications.

On examination he was conscious , well oriented and mobile with regular pulse

96 bpm and BP 80/6o with diminished perepheral pulses. He pale , not icteric

Not cyanosed with dry peripheries and flat neck veins.

Systemically he was ok except slight tenderness on right hypochondrial region.

Discussion:

Now this middle age guy has developed acute kidney injury. And the reason for

This is quit well infromed for his low blood pressure with significand heart disease

With medication whose names are not described. Well we can presume medication

In this scenario would be diuretic , ace inhibitors, anti platelets, Beta blockers etc.

This could cause volume depletion and AKI. ACE inhibitors can cause AKI.

He might have developed unstabel angina/MI which has cused AKI. He may have atherembolic disease.

Case Discussion

30 year male admited through emergency in a severe metabolic acidosis state and drowsy.

He had outside s.creatine of 15mg/dl, and xray showing homogenous opacity involving right

Apex of lung. There was recent history of taking ATT, which he soon gave up after using few

Days as he became more nauseated and had vomiting too. There was an aditional history of

Difficulty in passing urine since many years, and also required once catheterization suprapubically.

We got him inserted Double lumen cather and dialysed , later on Ultrasound kidneys and bladder

Showed markly dillated PC system leaving no cortex bilatteraly and thick wall , mild trabeculated

Bladder.

We concluded that he would be having stricture urethra by his tory which was substaciated with

The fact  when he was tried to pass cather but failed to proceed and subsequently suprabubic cathe

Erization done as he was in retention of urine.

Regarding his homogenous opacity in lung we would work him up for tuberculosis by Blood CP, ESR

Mauntox test, Sputum AFB or moring gastric lavage for AFB or BAL. Urine Dr and C/s. 

Case Disscussion

A 65 year male known  Hypertension ,diabetic, controlled on diet was found collapsed in bath room. On exa: Drowsy, heart rate 50 bpm with BP 140/90 and Tem 36.8 C. Jvp not raised. Heart sound normal and chest clear. Abdomen normal. Left lower limb was externally rottated and painful to move and brusing to thigh.
Lab:     Hb 9.8, tlc 14000, plat 350000,

t bili 1.4, AST 26,  Alp 109 , Alb 4.0,
Urine : blood 2 plus, prot 1 plus,
chest xray normal , xray hip show fracture and dislocation of neck of femure.
ECg : minor t wave abnormalties in lateral leads.


Question: What is diagnosis?
What is the cause of metabolic abnormality and how will u manage the patient?



Answere:  Diagnosis is Rhabdomyolysis. There are two important clues. One is that patient had a fall. Second there is renal failure with disproportionally raised creatine. There is muscle injury ( myositis). Myoglobin is released which is toxic to renal tubules and precipitate renal failure. calcium is found decrease and it binds with myoglobin and potassium and phosphate are high and there are liberated heavilly from damaged muscles.
The management involves adequate hydaration and alkalinization of the urine to reduce precipitation of myoglobin in the renal tubules. Avoid loop diuretic as they cause acidic urine.

Spina Bifida(Neurogenic bladder.)

 Neurogenic bladder , which is usually treated by ileal conduit. It is urinary diversion procedure in which terminal part of intestine , Ileum is dissected and anastomosed with ureters with one end and second end with skin (Stoma formation). we often come across cases in nephrology practice where patients with history of Spina bifida come as renal failure which is complication of this neurogenic bladder.
Now these patients usually need renal replacement therapy. Whenever we consider Peritoneal dialysis in these patients, we must consider patients ventriculo-peritoneal shunt which is often placed in these pateint because of Hydrocephalous. Therefor these children would be prone to meningitis if PD is initiated.

Interstitial nephritis

How interstitial nephritis is presented and what are the some of the drugs which cause?

It is usually presented with fever. maculopapular rash, eosinophilia, eosinophilurea.

Penicillin analogue, cephalosporin, sulphonamide, NSAIDs, cimitidine, allopurinol etc.
