A system and method for rating the severity of psoriasis in a patient is provided. In one embodiment, the system includes: a first logic for categorizing psoriasis plaque qualities into one of a plurality of categories of increasing severity for at least one target area of the patient based on an assessment of each psoriasis plaque quality for each corresponding target area, the psoriasis plaque qualities including elevation plaque quality, erythema plaque quality, and scale plaque quality and a second logic for classifying the severity of psoriasis for each target area into one of a plurality of classes of increasing severity based on the categorized psoriasis plaque quality with priority given to the categorized elevation plaque quality over other categorized plaque qualities. In another embodiment, the system also includes a third logic for assessing the psoriasis plaque qualities of each target area of the patient.

Methods for rating the severity of psoriasis in a patient are provided. Such methods comprise assessing the percent of the patient's body surface exhibiting signs of psoriasis, assessing the overall elevation, erythema, and scale of the patient's psoriasis plaques, and classifying the severity of the patient's psoriasis into at least four classes based upon the percent of the patient's body surface exhibiting signs of psoriasis adjusted by the overall elevation, erythema and scale of the patient's psoriasis plaques. In the present methods the weight given to one or more of the overall qualities of elevation, erythema or scale of the patient's psoriasis plaques in classifying the severity of the patient's psoriasis into a higher class is greater than the weight given to other of the overall qualities. A computer readable medium and system for practicing the present methods are also provided.

A telecommunication method and apparatus includes at least one bypass carrier code for completing a telecommunication connection between a telecommunication device and a communication network. The bypass carrier code is automatically entered for each outgoing toll and long distance call requiring a long distance carrier whenever a telephone number is input through a keypad or selected from a plurality of prestored memory telephone number locations. In one aspect, the bypass carrier code is stored in the memory of the telecommunication device. In alternate aspects, the bypass carrier code is re-programmable through the keypad or other numeric input on the telecommunication device or selectable by an input selector from a plurality of discrete bypass carrier codes.

Treatment of post-inflammatory hyperpigmentation (PIH) in black and asian skin is accelerated from natural healing by use of a composition comprising a retinoid and/or an inhibitor of cytochrome P-450 enzyme-mediated degradation of retinoids, the composition does not require a conventional depigmenting or bleaching agent (such as a hydroquinone) as is typically used. Healing of PIH lesions is accelerated about three to five times from normal healing. Additionally, these compositions are useful separately for lightening black or asian skin.
