Insights

Systemic lupus erythematosus (SLE) in a mother was linked to neonatal lupus erythematosus (NLE) in her daughter. Monitoring for cardiac conduction disturbances is crucial in infants born to mothers with anti-SSA antibodies due to potential risks.

Area of Science:

  • Immunology
  • Rheumatology
  • Pediatrics

Background:

  • Systemic lupus erythematosus (SLE) is an autoimmune disease with diverse clinical manifestations.
  • Neonatal lupus erythematosus (NLE) is a rare condition affecting infants born to mothers with specific autoantibodies.
  • Anti-nuclear antibodies (ANA) and anti-SSA antibodies are frequently associated with SLE and NLE.

Observation:

  • A 42-year-old woman diagnosed with SLE presented with positive ANA and anti-SSA antibodies.
  • Her daughter exhibited cutaneous lesions characteristic of NLE.
  • Infants with NLE are at risk for developing cardiac conduction disturbances.

Findings:

  • The presence of anti-SSA antibodies in mothers with SLE is a significant risk factor for NLE in their offspring.
  • Neonatal lupus erythematosus can manifest with skin lesions and potentially severe cardiac complications.
  • Cardiac conduction disturbances in NLE are linked to substantial morbidity and mortality.

Implications:

  • Early detection and monitoring of NLE are essential for affected infants.
  • Close surveillance for cardiac conduction abnormalities is warranted in neonates born to mothers with anti-SSA antibodies.
  • Understanding the maternal-fetal transmission of autoimmunity aids in managing NLE and its complications.

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Skin Diseases and Disorders01:23

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
