congenital abnormalities Flashcards
what is achondroplasia
Achondroplasia is a genetic disorder with an autosomal dominant pattern of inheritance whose primary feature is dwarfism
- short stature, shotended arms and legs, large head to body size, abnroaml hadn appearance with space between fingers, bowed legs and decreased muscle tone
Sutures allow growth and development of the head , you don’t want early fusions of the sutures either
what is craniosynostosis and what complication
where the bones in the head join way to early together and this could lead to hydrocephalus
what is plagiocephaly
head flattened on one side usually down to sleeping position
what is scaphocephaly
narrow and long skull shape in sagittal craniosynostosis due to premature fusion of the sagittal suture
Brachycephaly
the back of the head becomes flattened, causing the head to widen, and occasionally the forehead bulges out- baby sleeping on back
downs syndrome list features go
– broad flat face and flattened nasal ridge, widening of eyes- intrapapillary distance, up slanting palpebral fissures, umbilical hernia, small palate and hands , Problems include AVSD, VSD, PDA , duodenal atresia diagnosed with bilious green vomit ( double bubble sign on xray, gas bubble seen in duodenum just prior to the atresia, due to ari from stomach being between the pylorus sphincter and end of duodenum – surgical fix duodenoduodenostomy) , ALL, Alzheimer’s later life, thyroid , sleep disroders
frontal bossing
overgrowth syndromes
Single gene defects - Dominant
hereditary spherocytosis
achondroplasia
neurofibromatosis
single gene defects - recessive
CF (meconium ileus- babies first stool is so thick and sticky causing internal obstruction , meconium may not pass for 48hr – xray bubbly appearance, managed with drip and suck , IV fluids and stomach drain ( ryles) – DELTAF5O8 ) pancreatic deficiency and deficiency in vit ADEK – fat soluble vitamins
- sickle cell -african American
- CAII
what is hirschprung disease
– delayed passing of meconium over 48hr 1st pass, distended abdo and forceful evacuation of meconium after digital rectal examination -CCHS, rectal biopsy of different segments , poor weight gain, removal of section of ganglionic colon and healthy bowel pulled through is treatment
CHARGE syndrome
collarbone - problems with their senses of sight, hearing, smell, taste and touch. Deaf blindness at birth
anaerobic bacteria treated with what abx
metronidazole
Turner syndrome 45XO features
Short stature, constriction of aorta, poor breast development, widely spaced nipples, elbow deforms, no periods nad female – get them an echocardiogram , lymphoedema of hands and feet, webbed neck
Gastroschisis vs Exomphalos ( omphocele)
Gastroschisis is a defect of the abdominal wall, which results in your baby’s bowel being outside of their tummy. This means the bowel is not protected by any membrane or sac. Exomphalos is a defect at the base of the umbilical cord. It causes the bowel to push through (herniate) into the umbilical cord.
Developmental dysplasia of the hips features
Developmental dysplasia of the hips – hip within a shallow acetabulum, subluxation, frank dislocation , delayed walking, leg crease asymmetry, leg length discrepancy, clicky hips
