Accessory Structures of the Skin: Sebaceous Glands01:21

Accessory Structures of the Skin: Sebaceous Glands

4.5K
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...

Finding the Center of Gravity01:03

Finding the Center of Gravity

4.4K
The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Respiratory System Abnormal Finding I: Inspection and Percussion

868
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Finding Electric Potential From Electric Field01:13

Finding Electric Potential From Electric Field

5.7K
For a system of charges, it is easy to calculate the system's potential because potential is a scalar quantity. However, in some instances where calculating the electric field is more straightforward than finding the potential, the electric field is used to calculate the system's potential. For a positive charge, the electric field is radially outward, and the potential is positive at any finite distance from the positive charge. In such an electric field, the motion away from the...

Finding Volume Using Cross-Sectional Area01:24

Finding Volume Using Cross-Sectional Area

102
For solids whose cross-sectional areas vary in a predictable way, volume can be determined by integrating these areas along an axis perpendicular to the slices. This approach is particularly useful for polyhedral solids, where classical geometric formulas may not be immediately applicable. A tetrahedron provides a clear example of how cross-sectional integration can be applied to a three-dimensional object with continuously changing geometry.Consider a tetrahedron with height h and a base that...

Summary

Children with extensive craniofacial sebaceous nevus require brain imaging and eye exams due to high rates of associated abnormalities. Early surgical excision may improve scarring outcomes.

Area of Science:

  • Dermatology
  • Pediatric Surgery
  • Medical Genetics

Background:

  • Sebaceous nevus is a congenital skin malformation, typically on the scalp or face.
  • Syndromic forms can involve cerebral and ocular abnormalities.
  • Tumors may develop in adult patients; early childhood surgery can improve scar results.

Purpose of the Study:

  • Analyze cases of syndromic sebaceous nevus.
  • Review existing literature on the condition.
  • Propose therapeutic guidelines for syndromic sebaceous nevus.

Main Methods:

  • Retrospective study of syndromic sebaceous nevus cases.
  • Data collected from Montpellier, France and Lausanne, Switzerland (1994-2016).

Main Results:

  • Six pediatric patients with syndromic sebaceous nevus analyzed; average age at consultation was 4 months.
  • All cases had craniofacial lesions; 2/6 showed abnormal cerebral imaging.
  • All 4 patients with ophthalmic exams had abnormalities; 3 had other malformations.

Conclusions:

  • Extensive craniofacial sebaceous nevus warrants cerebral imaging and ophthalmic evaluation due to high associated abnormality rates.
  • Developmental issues were not definitively linked to the skin malformations in this study.
