Insights

Myringosclerosis, a middle ear condition, affects 32% of hemodialysis patients. This study found no strong link between myringosclerosis and hyperparathyroidism in these patients.

Area of Science:

  • Otolaryngology
  • Nephrology
  • Pathology

Background:

  • Myringosclerosis involves collagen overproduction, hyalinization, calcification, and potential metaplasia in the middle ear.
  • A similar pathological sequence is observed in hyperparathyroidism associated with chronic kidney disease.

Purpose of the Study:

  • To determine the prevalence of myringosclerosis in hemodialysis (HD) patients.
  • To investigate the association between hyperparathyroidism and myringosclerosis in chronic HD patients.

Main Methods:

  • 86 chronic HD patients were evaluated.
  • Patients were categorized into two groups: myringosclerosis-negative (n=58) and myringosclerosis-positive (n=28).
  • Serum parathyroid hormone, creatinine, ferritin, and red blood cell mean corpuscular volume were analyzed.

Main Results:

  • Myringosclerosis was present in 32% of the studied HD patients.
  • No statistically significant difference in serum parathyroid hormone levels was found between groups.
  • Significantly higher serum creatinine, lower serum ferritin, and significantly lower mean corpuscular volume were observed in the myringosclerosis-positive group.

Conclusions:

  • Myringosclerosis is prevalent in 32% of chronic HD patients.
  • No strong correlation was found between myringosclerosis and hyperparathyroidism in this cohort.
  • Further research may explore the association with other biochemical markers.

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Hemodialysis I: Introduction

Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

The Parathyroid Glands00:59

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Hemodialysis III: Nursing Management

The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Peritoneal Dialysis III: Nursing Management

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...
