Summary
Pityriasis Alba (PA) in children is linked to lower levels of hemoglobin, zinc, copper, and magnesium. Sun exposure and skin type are also identified as key risk factors for this common skin condition.
Area of Science:
- Pediatric Dermatology
- Nutritional Biochemistry
- Clinical Research
Background:
- Pityriasis Alba (PA) is a prevalent pediatric skin condition with various contributing factors.
- Understanding the biochemical profile associated with PA is crucial for effective management.
Purpose of the Study:
- To investigate serum levels of trace elements (copper, zinc, magnesium) and hemoglobin (Hb) in children diagnosed with Pityriasis Alba.
- To identify potential nutritional deficiencies and their correlation with PA.
Main Methods:
- A case-control study involving 110 children (55 with PA, 55 controls) aged 6-16.
- Analysis of sociodemographic data, clinical history, and dermatological examination.
- Biochemical assessment of serum trace elements and hemoglobin levels using SPSS software.
Main Results:
- Significantly lower levels of hemoglobin, serum ferritin, copper, zinc, and magnesium were observed in the PA group compared to controls.
- Zinc deficiency was associated with a >15-fold increased risk of PA.
- Reduced Hb levels increased PA risk by over ninefold (OR 9.6).
Conclusions:
- Pityriasis Alba is associated with deficiencies in hemoglobin, serum zinc, ferritin, copper, and magnesium.
- Sun exposure and skin phototype are significant risk factors for developing PA.
- These findings highlight the importance of nutritional status and environmental factors in PA pathogenesis.

Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to...

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.

4.0K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...

Although Mendel chose seven unrelated traits in peas to study gene segregation, most traits involve multiple gene interactions that create a spectrum of phenotypes. When the interaction of various genes or alleles at different locations influences a phenotype, this is called epistasis. Epistasis often involves one gene masking or interfering with the expression of another (antagonistic epistasis). Epistasis often occurs when different genes are part of the same biochemical pathway.
