Osteogenesis Imperfecta
  1. Pathophysiology
    1. Hereditary disorder of bone fragility caused by mutations in various collagen producing genes (Rush, 2016). This can be classified into groups.
      1. Group A: Collagen structure & function defects (Rush, 2016)
        1. Group C: Collagen folding and cross-linking defects (Rush, 2016)
          1. Group E: Osteoblast development defects with collagen insufficiency (Rush, 2016)
            1. Group D: Ossification or mineralization defects (Rush, 2016)
              1. Group B: Collagen modification defects (Rush, 2016)
                1. TYPES?????
              2. Epidemiology
                1. Nursing Considerations
                  1. Psychosocial Support
                    1. Reassure parents not to feel guilty regarding child’s diagnosis - Educate parents on how OI does not affect a child’s ability to think and learn - Referral to genetic counsellor - Offer emotional support to both parents and patient – demonstrate empathy, active listening, social worker referral, chaplain - Recognize stages of grief: denial, anger, bargaining, depression and acceptance and offer. Encourage families to express these feelings and explain they are normal - Offer various resources such as: Osteogenesis Imperfecta Foundation website (www.oif.org) and phone number: 1-800-981-2663 - Referrals to local OI support group, pediatrician, pediatric orthopedist, physical therapist should be provided
                    2. Handling
                      1. - Educate parents with demonstration and explanation of proper holding, lifting, feeding and general infant care procedures - Get to parents to do a return demonstration to ensure learning has occurred - Provide reading material and educational resources such as brochures from OI foundation etc. - Provide teaching regarding recognizing new fractures and protecting the injured body part while travelling to the hospital or clinic - Advise parent regarding choosing clothing with wide openings since it’d allow for the garment to slide over the infant’s arms or legs without pulling the limbs
                      2. Bedding and positioning
                        1. Waterbeds and soft bedding should never be used - Regular crib mattress is recommended for a baby with OI - Position the infant to prevent plagiocephaly: use rolled blankets/sheets or soft foam to support side lying position
                        2. Parent teaching
                          1. - Educate parents with demonstration and explanation of proper holding, lifting, feeding and general infant care procedures - Get to parents to do a return demonstration to ensure learning has occurred - Provide reading material and educational resources such as brochures from OI foundation etc. - Provide teaching regarding recognizing new fractures and protecting the injured body part while travelling to the hospital or clinic - Advise parent regarding choosing clothing with wide openings since it’d allow for the garment to slide over the infant’s arms or legs without pulling the limbs
                          2. Feeding
                            1. - Small, frequent feeds: babies may be poor feeders and may have weak sucking reflex - Breast milk recommended: excellent source of nutrition • Fosters special bond between mother and child • If infant unable to breastfeed due to inability to suck or risk of aspiration due to rapid respirations: offer mom to pump breast milk and feed the child from a bottle - Burp the baby cautiously: gently lift the baby and soft taps with padding over hands are recommended
                          3. Clinical Manifestations (OI, n.d.)
                            1. Type I: Most common/ mildest form
