by 5 years of age.
Signs and symptoms reflect the tumor site and extent of disease, but may include fever, failure to
thrive, bone pain, cytopenia, orbital proptosis, masses, bowel obstruction, or spinal cord
compression.

Adolescent lesbian and bisexual females are more likely to have been pregnant when compared

LGB adolescents and young adults are at greater risk for unplanned pregnancy and, it is
important to counsel about accidental pregnancy even with females who have sex with females.
Providing sexual and reproductive health education that includes information about abstinence,
contraception, and sexually transmitted infections (STIs) is necessary for all adolescents and
young adults. Additionally, information about contraception should be offered to all females
regardless of their sexual orientation.
Pre-college visits present an excellent opportunity to ensure that all immunizations are current,
not just the human papilloma virus vaccine. Adolescents and young adults, including those who
know or are unsure about their sexuality, may have psychosocial concerns. Providing care that is

confidential, current, factual, and nonjudgmental is required with all patients, regardless of their
sexual orientation.
While some characteristics of an Individualized Education Plan (IEP) and 504 Plan are similar,
the IEP differs in that it uniquely requires
A. a specific medical diagnosis for eligibility.
B. a modification in curriculum to meet the student's needs.
C. an evaluation typically completed through school system resources.
D. a written plan be developed that specifies individualized accommodations.
B. a modification in curriculum to meet the student's needs.
Eligibility for both plans requires a medical diagnosis. For a 504 Plan, this can be any
psychologic or physical disorder which "substantially limits" the individual's learning. These
children can follow the curriculum without modification but may require assistance in the school
setting. This may include conditions such as ADHD, diabetes, or migraines.
In order to be eligible for an IEP, a child has to also have a medical diagnosis, but that diagnosis
must specifically meet criteria as a qualifying disability that seriously affects learning or
behavior and, therefore, requires modification of the school curriculum.
Both a 504 and an IEP require evaluation, although the evaluation for an IEP is more formalized
and is typically completed by a team of professionals. Both an IEP and a 504 plan will include a
written plan. There are no legal requirements for what is included in a 504 plan and there is no
mandated re-evaluation. An IEP has very specific criteria and must describe the specific learning
problems, detail what services will be provided, set annual goals and define how progress will be
measured. Re-evaluation is mandated every 3 years.

A. normalize desquamation of the follicular epithelium.
B. minimize development of antibiotic-resistant Cutibacterium acnes (formerly
Propionibacterium acnes).
C. generate free radicals to oxidize proteins in the cell wall of Cutibacterium acnes.
D. work within the cell ribosomes to alter upstream signals affecting inflammatory pathways.
A. normalize desquamation of the follicular epithelium.
The therapeutic objectives in the management of acne vulgaris are to reduce sebum production,
prevent formation of microcomedones, suppress Cutibacterium acnes (formerly
Propionibacterium acnes), and reduce inflammation to prevent scarring.
Topical retinoids, vitamin A derivatives that bind to retinoid receptors in the skin, are a key
component of primary acne management. Topical retinoids normalize desquamation of the
follicular epithelium to prevent new formation of microcomedones, the precursors of both
comedonal and inflammatory lesions. Additionally, retinoids promote clearing of existing
microcomedones and work within the nucleus to alter downstream signals that affect
inflammatory pathways.
