Abstract:
A 5-year-old male child with complaints of failure to thrive (since 4 months of age) and developmental delay presented to the nephrology department with complaints of weakness in all four limbs for 5 days. On examination, he was hypotensive, dehydrated, and had reduced tone in all four limbs. Biochemistry revealed acute kidney injury (AKI), hyponatremia, hypocalcemia, and hypokalemia. Renal needle biopsy (in view of unexplained AKI) revealed ropy, granular pigment casts with marked tubular injury. Myoglobin stain was positive. The positive genetic analysis of the patient (CLCNKB gene) confirmed the clinical diagnosis of Bartter syndrome (BS). The child was managed with aggressive intravenous hydration with potassium and calcium supplementation, and AKI recovered.

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Proximal Convoluted Tubule (PCT):
The PCT is the initial segment of the renal tubule, extending from the Bowman's capsule that encloses the glomerulus. Its convoluted structure and microvilli-lined cells increase the surface area for reabsorption. The PCT reabsorbs glucose, amino acids, sodium, and water from the filtrate, ensuring essential...
