Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

5.3K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Inborn Errors of Metabolism

967
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Pathophysiology of Diabetes

4.0K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

1.1K
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Disorders of the Skeletal Muscle

2.1K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Summary
This summary is machine-generated.

Nonketotic hyperglycemia can initially manifest as hemichorea-hemiballism, a movement disorder. This condition, associated with high blood sugar, may be the first sign of diabetes mellitus.

Area of Science:

  • Neurology
  • Endocrinology
  • Movement Disorders

Background:

  • Hemichorea-hemiballism is a rare hyperkinetic movement disorder.
  • It can be associated with metabolic disturbances, particularly hyperglycemia.
  • New-onset diabetes mellitus is a potential underlying cause.

Purpose of the Study:

  • To investigate the association between hemichorea-hemiballism and nonketotic hyperglycemia.
  • To highlight this presentation as an initial manifestation of diabetes mellitus.
  • To review existing literature on hyperglycemia-induced movement disorders.

Main Methods:

  • Case report analysis.
  • Literature review of similar cases.
  • Review of clinical and biochemical data.

Main Results:

  • Hyperglycemia, specifically nonketotic hyperglycemia, was consistently observed in affected individuals.
  • Hemichorea-hemiballism resolved or improved with glycemic control.
  • In some cases, this movement disorder was the presenting symptom of previously undiagnosed diabetes mellitus.

Conclusions:

  • Nonketotic hyperglycemia should be considered in the differential diagnosis of new-onset hemichorea-hemiballism.
  • Prompt management of hyperglycemia is crucial for neurological recovery.
  • This presentation underscores the importance of metabolic screening in movement disorder evaluations.
