Flashcards in second and third trimester Deck (23):
1

clinicaal manifestations Toxoplasmosis

 

dx

First trimester - death

Second - hydrocephalus, intracranial calcifeications, chorientiitis

Third - asymptomatic at birth

dx via IgM (igG is more indicative of chronic)

1

CMV infection histology

owl eye basopihlilc inclusions in nucleus

2

second trimester complications

TORCH

cervical insufficiency

fetal anomalies

3

rubella, virus and clincical 

Togavirus

deafness

eye - cataracts or retinopathy

cns defects

cardiac malformations 

4

fetal HSV cliinical 

Congenital (rare)

microcephaly

ventriculomegaly

spasticity

echogenic bowel
hepatosplenomegaly

flexed extremities

4

Preterm premature rupture of membrane =

risk factors

dx

chorioamniotic rupture before onset of labor in

Risk: preterm labor, shortcervix,advanced  cervical dilation

 

dx: direct visualization of fluid and ferning on microscopy

4

macrosomia = 

 

risk factors

estimated weight >4500g

 

incorrect dates, maternal diabetes, excessive weight gain, maternal obesity

6

fetal clincial manisfestation parvovirus

anemia

acute muycarditis

edema/hydrops

intrauterine demise

7

Tzanck smear

wrights stain with vescular materia showiing multinucleated giant cells and viral inclusions in HSV infection 

9

dx fetal syphillis

screening - RPR and vDRL

FTA-ABS and MHA test confirm

10

placenta previa = 

 

presentation

risk factors

placenta over or near intternal os

painless, no contractions 

risk: smoking, advanced age, multiple gestation, uterine anomlies, scaring from previous pregnancies

12

TORCH infections

Toxoplasmosis
Other (Syphillis, Parvovirus B19)

Rubella

Cytomegalovirus

Herpes simplex virus

13

hemorrhage secondary to placental abnls (placenta previa. accreta, abruption, velamentous cord isertion) occur duing

third trimester

13

intrauterine growth restricion = 

estimated fetal weight

14

placenta abruption -=

 

resentatoin

risk factors

placental separation due to heorrhage into decidual basalis before birth

presents: vaginal bleeeding, uterine tenderness, contractions (with or without hearttones)

risk: prior abruption, trauma, PPROM, HTN, smoking, cocaine

14

velamentous cord insertion =

cord to chroion and amnior rather than placenta

16

fetal CMV clinical

periventricular calcifications

intrauterine growth restriction
developmental delay
microecephaly
senosrineural hearing lsos
retinitis 
Jaundice + hepatospenomgaly
trhombocytopenia
hypotonia

18

risk  factos for preterm 

 

dx

premature activation of maternal or fetal hypothalamic =-pituitary - adrenalaxis

exaggerated inflammatory respoinses or infection

abruption 

pathological uterine distension 

dx: regular contarctions resulting in cervical dilation 

19

placenta accreta 

placenta increta

placenta percreta

implantation extends into basal zonne of endometrium

risk for heorrhage and hysterectomy after delivery

increta - into myometrium

percreta - into uterine serosa or other organs
(risk factors = multiple c-sections, placenta previa)

20

risk factor cervical insuffieicny

collagen abnls

uterine anomalies

prior obstetric trauma

mechaniical dilation

prior 2nd trimester loss

21

trasmission CMC

transplacental

perinatal

contact with body fluids

22

syphillis fetal infection presentations

spontatnesous abortion (first trimester)

still birth

non-immune hydrops

preterm

heaptomegaly

ascites

anemia, thrombocytopenia

23

toxplasma gondii transmission

fecal oral

transplacental
