Poor Feeding
After ten days, the baby was seen by the primary-care physician (PCP) for a new-onset fever and poor feeding. The patient was put on amoxicillin for otitis media but no clinical improvement ensued. [file.scirp.org]
Prevention of Secondary Complications Poor feeding and recurrent aspiration necessitate the placement of a gastrostomy tube. Note: Improved nutrition does not enhance linear growth. [ncbi.nlm.nih.gov]

Treatment
TREATMENT Treatment for Rhizomelic Chondrodysplasia Punctata Type 1 is symptomatic depending on the features of an individual. [evolvegene.com]
Management and treatment There is no specific treatment for the enzyme defect. Prognosis Rhizomelic chondrodysplasia has a severe prognosis with death generally occurring during the first decade of life, mainly due to respiratory complications. [orpha.net]
Treatment Treatment Options: No treatment is available beyond supportive measures. Cataract removal may improve vision but the poor prognosis for longevity requires caution be used. [disorders.eyes.arizona.edu]
TREATMENT There is no current cure for RCDP. Treatment is supportive and many include physical therapy, anti-seizure medication, hearing amplification, and cataract removal. [secure.ssa.gov]
