A 60-year-old man has had painful skin with exfoliation of the skin and mucous membranes for 1 day. He has been taking allopurin

ol and probenecid for 2 weeks because of gouty arthritis. There is diffuse exfoliation of the skin with oozing of serous fluid. The mucous membranes of the mouth are erythematous and exfoliated. There are no target lesions. Which of the following is the most likely diagnosis?A. Bullous pemphigoidB. Erythema multiformeC. Pemphigus vulgarisD. Staphylococcal scalded-skin syndromeE. Toxic epidermal necrolysis

Answer:

The correct answer is option E, that is, toxic epidermal necrolysis.

Explanation:

The painful exfoliation of the mucous membranes and the skin two weeks after starting allopurinol indicates Toxic Epidermal Syndrome. A potentially life-threatening dermatologic ailment featured by widespread necrosis, erythema, and bullous detachment of the mucous membranes and epidermis is known as the toxic epidermal necrolysis. The further leads to exfoliation, and possible death or sepsis.

icang [17]
1. breeding of individuals that have genes for two different characteristics:
DIHYBRID CROSS.
We call it a dihybrid cross when we are considering a cross between two different traits.
"di" means having two traits involved (for example, trait A and trait B), the "hybrid" means that each trait will have two different alleles (for gene A: A or a; for gene B: B or b), one is dominant and the other is recessive.

2. a grid system used to predict possible combinations of genes due to random fertilization: PUNNETT SQUARE
The Punnett square is a grid system that helps us predict an outcome of a cross or a breeding experiment. We this, we can determine the probability of an offspring having a particular genotype.
This is very useful when we are considering more than one gene,  making it less confusing.

3. a condition in which both alleles are dominant: CODOMINANCE
Tere are alleles that have the capacity of dominating at the same time, and when an organism is heterozygotic, both alleles are expressed.
For example, a white chicken(WW) crossed with a black chicken (BB):  100% of the offspring being WB. With this genotype, they have black feathers and white feathers. It's not a blend of colors, but a case where both are expressing.

4. when more than two alternatives exist for a gene: MULTIPLE ALLELES
Mendel thought that only two possible alternatives could exist for a gene, but there are cases that have more than 3 possibilities. Some of those can be really popular in a population while others not so much.
This happens with rabbit's fur. They can be black, brown, grayish,
Himalayan patterning or white fur.

 5.a condition in which neither pair of alleles is dominant or recessive, so the traits blend in the phenotype: INCOMPLETE DOMINANCE
Some alleles are not completely dominant, and when that's the case the phenotype of a heterozygous organism will be a mix between the phenotypes of its homozygous parents.
For example:
plant 1: RR -red
plant 2: rr-white
By crossing this plants we will obtain 100%  of the offspring with a color mix: pink.(genotype: Rr)
Red and white are not completely dominating so it results in a blend of colors.
