  • Care of Infants and Children
    AAFP Reprint No. 260 Recommended Curriculum Guidelines for Family Medicine Residents Care of Infants and Children This document was endorsed by the American Academy of Family Physicians (AAFP). Introduction This AAFP Curriculum Guideline defines a recommended training strategy for family medicine residents. Attitudes, behaviors, knowledge, and skills that are critical to family medicine should be attained through longitudinal experience that promotes educational competencies defined by the Accreditation Council for Graduate Medical Education (ACGME), www.acgme.org. The family medicine curriculum must include structured experience in several specified areas. Much of the resident’s knowledge will be gained by caring for ambulatory patients who visit the family medicine center, although additional experience gained in various other settings (e.g., an inpatient setting, a patient’s home, a long-term care facility, the emergency department, the community) is critical for well-rounded residency training. The residents should be able to develop a skillset and apply their skills appropriately to all patient care settings. Structured didactic lectures, conferences, journal clubs, and workshops must be included in the curriculum to supplement experiential learning, with an emphasis on outcomes-oriented, evidence-based studies that delineate common diseases affecting patients of all ages. Patient-centered care, and targeted techniques of health promotion and disease prevention are hallmarks of family medicine and should be integrated in all settings. Appropriate referral patterns, transitions of care, and the provision of cost- effective care should also be part of the curriculum. Program requirements specific to family medicine residencies may be found on the ACGME website. Current AAFP Curriculum Guidelines may be found online at 1 www.aafp.org/cg.

  • ENCOPRESIS Information for Children and Parents
    ENCOPRESIS Information for children and parents Children with encopresis have bowel movements in the wrong places, such as underwear and nightclothes. This is called “soiling”. Sometimes the child will also pass stool in the toilet. Encopresis is very common, occurring in at least 1.5% of all children. What do You say? Families use many different words to mean “bowel movement” or “feces”. Does your child say “booboo” or “poop”? Some people say “number 2” or “make”. Doctors tend to say “bowel movement “ or “stool”, which are the words used in this pamphlet. Please let your doctor know what words will help your child to understand SYMPTOMS Encopresis usually follows constipation. The child may have stomach ache, cramps, vomiting, or bloating. Some children become pale or flushed, lose their appetites, or even lose weight. Some have small tears in the anal tissue called anal fissures. These are painful and can lead to blood in the stool. Children with this problem have different bowel habits. Some may not have any bowel movement for many days, and then have a huge, hard stool, large enough to block the toilet! Other children have daily bowel movements on the toilet but also leak liquid, diarrhea-like stool into their clothes. Some children do not stool in the toilet at all. Children may hide their soiled underwear in drawers or under the bed. This can be very unpleasant for other family members. Another common upsetting behavior is refusal to change dirty clothing even though the odor is very annoying to other people. The child with encopresis may not notice the unpleasant smell.

  • Outpatient Pediatrics, Continuity Clinic, and Office Based Rotations
    Outpatient Pediatrics, Continuity Clinic, and Office Based Rotations Description of Rotation: Residents on the outpatient rotation will examine and evaluate patients presenting with acute or chronic conditions. Their findings, impressions, and plans will be presented to an attending physician. The attending physician will examine all patients presented by PL-1 residents in their first six months of training. As residents gain more knowledge and experience, they will be given more autonomy. Residents will see their own private patients in their continuity clinic. Each resident will have their continuity clinic one half day per week. This will allow residents to follow patients longitudinally throughout their three years of residency training. These patients may be acquired through the newborn nursery, the emergency room, the inpatient service, or the general pediatric clinic. Responsibilities: Residents will arrive in the clinic at 8 am. They are expected to stay until all patient care and follow-up activities are completed for the day. They will be respectful to the patients, staff, and each other. They are required to attend the resident lecture series. Residents will notify the clinic director and the scheduling clerk if they are going to be absent. In case of vacation or CME, notification of clinic cancellation should occur as early as possible to allow for rescheduling of patients. Note: The goals and objectives described in detail below are not meant to be completed in a single one month block rotation but are meant to be cumulative, culminating in a thorough and complete outpatient experience at the end of residency. Primary Goals for this Rotation GOAL: Health Promotion and Screening.

  • Chapter 4: Gastrointestinal, Hepatic, and Nutritional Problems
    Fanconi Anemia: Guidelines for Diagnosis and Management Chapter 4: Gastrointestinal, Hepatic, and Nutritional Problems Introduction Good to Know The gastrointestinal system digests food and absorbs the nutrients our bodies need to function properly. This system is a complex group of cells organized as a long, hollow tube that begins at the mouth, continues through the esophagus, stomach, and intestines, and ends at the anus. The liver aids digestion by producing bile, which helps the body break down fats. The liver also clears some toxins from the body and synthesizes certain nutrients. Both Fanconi anemia (FA) and medications used to treat the disease can cause gastrointestinal disorders, liver disease, and nutrition-related challenges. Many patients experience symptoms such as reduced appetite, nausea, abdominal pain, and diarrhea. Without proper treatment, these symptoms can interfere with daily living and create hurdles to healthy growth and development. Concerns related to the gastrointestinal tract most commonly include: • Abnormalities of the gastrointestinal tract • Gastrointestinal symptoms, including poor food intake, nausea, abdominal pain, and/or diarrhea • Poor weight gain or malnutrition, often resulting from reduced food intake or difficulty absorbing nutrients from food • Overweight or obesity • Cancers of the gastrointestinal tract • Liver disease • Gastrointestinal-related complications of hematopoietic stem cell transplant (HSCT) 74 Chapter 4: Gastrointestinal, Hepatic, and Nutritional Problems The gastrointestinal clinical care team should include a gastroenterologist or pediatric gastroenterologist and, when needed, a dietician. This team should work in close collaboration with other FA specialists to provide comprehensive care. The involvement of multiple types of providers in the care of patients with FA introduces the risk that medications prescribed by one physician might adversely interact with those prescribed by another.
