Insights

Severe hypercalcaemia requires prompt diagnosis to avoid life-threatening emergencies and unnecessary procedures. Clinical evaluation and basic tests accurately identified the cause in five patients, guiding effective treatment.

Area of Science:

  • Endocrinology
  • Nephrology
  • Medical Diagnostics

Background:

  • Hypercalcaemia is a common, potentially life-threatening condition.
  • Accurate diagnosis is crucial to prevent misdiagnosis and unnecessary interventions like parathyroidectomy.
  • Severe hypercalcaemia (calcium ≥3.5 mmol/L) presents diagnostic challenges.

Purpose of the Study:

  • To evaluate the effectiveness of initial clinical and biochemical assessments in diagnosing severe hypercalcaemia.
  • To demonstrate how early diagnostic steps can guide investigations and prevent delays.

Main Methods:

  • Retrospective review of five patients with severe hypercalcaemia at Sultan Qaboos University Hospital.
  • Analysis of clinical examination findings, fasting serum calcium, phosphate, creatinine, 24-hour urine calcium, and radiographic data.
  • Comparison of initial diagnostic accuracy with subsequent hormone assay results.

Main Results:

  • Most patients with severe hypercalcaemia had been misdiagnosed for extended periods.
  • Clinical examination and basic laboratory tests (serum calcium, phosphate, creatinine, urine calcium) accurately predicted the underlying cause.
  • These initial evaluations successfully guided further diagnostic procedures before hormone assays were completed.

Conclusions:

  • Early clinical and biochemical assessment is highly effective in diagnosing severe hypercalcaemia.
  • A systematic approach using readily available tests can prevent diagnostic delays and inappropriate treatments.
  • This strategy ensures timely and accurate management of hypercalcaemia, improving patient outcomes.

Urinary Tract Calculi III: Medical Management

The diagnosis of renal calculi involves several imaging techniques, including non-contrast CT scans and ultrasound. These methods help visualize kidney stones, assess their size and location, and detect possible obstructions. Additionally, Measuring urine pH is useful for diagnosing specific stone types, such as struvite (alkaline pH) and uric acid stones (acidic pH). Cystine stones are primarily linked to cystinuria, a genetic condition. A urinalysis helps detect blood in the urine (hematuria)...

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Urinary Tract Calculi IV: Nutrition Therapy and Prevention

Management of renal calculi focuses on effective strategies like tailored nutrition and hydration therapy. Adjusting diet and fluid intake reduces stone formation and recurrence, making these interventions simple yet powerful in kidney stone prevention and management.Understanding Kidney StonesKidney stones form when calcium, oxalate, uric acid, and cystine concentrate and crystallize in urine. Factors contributing to their formation include genetic predisposition, certain medical conditions,...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Urinary Tract Calculi VI: Surgical Management

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...
