Herpes simplex keratitis (HSK) is a serious eye condition caused by the herpes simplex virus (HSV), particularly HSV-1. This viral infection affects the cornea, potentially leading to vision impairment or blindness if untreated. Early diagnosis and effective management are crucial for preserving ocular health. Causes of Herpes Simplex Keratitis The primary cause of herpes simplex
Herpes simplex infection is a common viral condition caused by the herpes simplex virus (HSV). This virus exists in two primary forms: HSV-1, which is commonly linked to oral herpes, and HSV-2, responsible for genital herpes. Both types are highly contagious and can cause recurring outbreaks. Understanding the virus’s transmission, symptoms, and management is essential
Herpes simplex hepatitis (HSH) is a rare yet severe viral infection caused by the herpes simplex virus (HSV). This condition predominantly affects immunocompromised individuals, pregnant women, and neonates. While HSV-1 is the most common cause, HSV-2 may also trigger this liver-related condition. Prompt diagnosis and treatment are crucial to improving outcomes. Causes of Herpes Simplex
Herpes Simplex Encephalitis (HSE) is a severe and potentially life-threatening condition caused by the herpes simplex virus (HSV), predominantly HSV-1. It is the most common cause of sporadic viral encephalitis worldwide and requires immediate medical intervention. Causes of Herpes Simplex Encephalitis HSE is caused primarily by HSV-1, the same virus responsible for cold sores. HSV-2,
Herpes simplex dendritic keratitis is a common form of viral keratitis caused by the herpes simplex virus (HSV). This condition predominantly affects the cornea, leading to painful eye symptoms and potential vision impairment. Early diagnosis and appropriate treatment are essential to prevent complications. What is Herpes Simplex Dendritic Keratitis? Herpes simplex dendritic keratitis is an
A herniated lumbar disc is a common spinal condition that occurs when the soft inner core of a spinal disc protrudes through its outer layer. This condition often results in lower back pain, leg pain, and other neurological symptoms. Anatomy of the Lumbar Spine The lumbar spine comprises five vertebrae (L1-L5) that provide flexibility and
Hereditary Tyrosinemia Type I (HT1) is a rare genetic disorder caused by a deficiency in the enzyme fumarylacetoacetate hydrolase (FAH). This enzyme is essential in the breakdown of the amino acid tyrosine. The absence of FAH leads to the accumulation of toxic metabolites in the liver and kidneys, resulting in severe complications. Causes of Hereditary
Hereditary orotic aciduria type I is a rare autosomal recessive metabolic disorder characterized by a deficiency in the enzyme uridine monophosphate synthase (UMPS). This condition affects pyrimidine biosynthesis, resulting in excessive excretion of orotic acid in the urine and impaired growth and development. Causes and Genetic Basis Hereditary orotic aciduria type I is caused by
Hereditary Factor XIII (FXIII) deficiency is a rare genetic bleeding disorder characterized by impaired blood clotting due to low levels or dysfunction of Factor XIII. This condition is inherited in an autosomal recessive pattern and can result in severe bleeding episodes if untreated. Causes of Hereditary Factor XIII Deficiency Factor XIII deficiency results from mutations
Hereditary Factor XIII A subunit deficiency is a rare congenital bleeding disorder resulting from mutations in the F13A1 gene. This condition impairs the blood’s ability to form stable clots, leading to prolonged bleeding episodes and other complications. What is Factor XIII A Subunit Deficiency? Factor XIII (FXIII) is a crucial clotting factor composed of two
