What is optimal solution of an LPP?

- The optimal solution is the corner point that yields the maximum value of Z (if maximizing) or the minimum value of Z (if minimizing). This point is where the objective function reaches its best value according to the problem's requirements.wood lamp dermatology

What are the criteria for diagnosis of lichen planus?

The 6 'Ps' of LP are 'Pruritic, Purple, Polygonal, Planar, Papules, and Plaques' (14). The lesions are usually bilateral with relatively symmetric appearance. Oral lichen planus can occur solitary or with simultaneous cutaneous or mucosal manifestations (e.g., genital area, gastrointestinal tract, eyes, etc.)

What is lichen planus pigmentosus dd?

Introduction. The term lichen plans pigmentosus (LPP) was first used by Shima in 1956 for a condition considered to be a variant of lichen planus. [1] It is characterized by insidious onset of blue–brown macules over the sun-exposed areas and the flexures. Rarely, involvement can be generalized.melasma dermoscopy

What is the best cream for lichen planus?

High-potency topical corticosteroids should be first-line treatments for all forms of lichen planus. Topical calcineurin inhibitors, such as tacrolimus (Protopic) and pimecrolimus (Elidel), should be used as second-line therapies to treat genital and oral lichen planus.

Can LPP be negative?

Usually, in an LPP problem, it is assumed that the variables xj are restricted to non-negativity. In many practical situations, however, one or more of the variables xj which can have either positive, negative, or zero value are called unrestricted variables.

What is lichen planus pigmentation?

Overview. Lichen planus (LIE-kun PLAY-nus) is a condition of the skin, hair, nails, mouth and genitals. On skin, lichen planus often appears as purple, itchy, flat bumps that develop over several weeks. In the mouth and genital mucosa, lichen planus forms lacy white patches, sometimes with painful sores.

What are the Dermoscopy findings of lichen planopilaris?

Lichen planopilaris

Trichoscopy reveals multiple irregular cicatricial alopecic areas with perifollicular whitish-gray scaling associated with erythema, arboriform vessels, absence of follicular openings and follicular plugging (Figures 2, 3).

Can cafe au lait spots suddenly appear?

Can café-au-lait spots suddenly appear in adulthood? Yes. Café-au-lait (CAL) spots are most often present on a newborn's skin but it is common for CAL spots to develop on a person's skin later in life. It is normal for a person to have a few CAL spots but more than six spots may be a sign of an underlying condition.

How can you tell the difference between lichen sclerosus and lichen planus?

The main difference between the two conditions is that LP has a propensity to involve the mucous membranes including the mouth and vagina which are rarely affected in LS. First-line treatment for LS is a super-potent topical corticosteroid ointment which has a high response rate.
