The ameloblastic fibro-odontoma (AFO) is essentially a benign tumor with the features characteristic of ameloblastic fibroma along with enamel and dentin (hard tissues). [4] Though it is generally regarded as benign, there have been cases of its malignant transformation into ameloblastic fibrosarcoma [ 5 ] and odontogenic sarcoma. [ 6 ]
The signs and symptoms of amniotic fluid embolism can vary from one individual to another but involve systemic involvement of multiple organ systems. Often, a patient may present with a cough due to the release of bradykinin , an inflammatory marker released during times of pain and which causes an anaphylactoid reaction . [ 4 ]
Polyhydramnios is a medical condition describing an excess of amniotic fluid in the amniotic sac.It is seen in about 1% of pregnancies. [1] [2] [3] It is typically diagnosed when the amniotic fluid index (AFI) is greater than 24 cm. [4] [5] There are two clinical varieties of polyhydramnios: chronic polyhydramnios where excess amniotic fluid accumulates gradually, and acute polyhydramnios ...
The use of oligohydramnios as a predictor of gestational complications is controversial. [23] [24] Potter syndrome is a condition caused by oligohydramnios. Affected fetuses develop pulmonary hypoplasia, limb deformities, and characteristic facies. Bilateral agenesis of the fetal kidneys is the most common cause due to the lack of fetal urine.
Other causes, albeit less frequent, are mutations in genes affecting other enzymes involved in steroid metabolism, like 11β-hydroxylase or 3β-hydroxysteroid dehydrogenase. [3] It has a prevalence between 0.1% and 2% depending on population, [ 2 ] and is one of the most common autosomal recessive genetic diseases in humans.
One main test that is performed on amniotic fluid is the L/S ratio test (lecithin/sphingomyelin). This test is used to determine fetal lung maturity. Both lecithin and sphingomyelin are lung surfactants that are present in increasing amounts in the maturing fetus, though past week 33, sphingomyelin levels remain relatively constant.

Erythroblastosis fetalis, also known as Rh disease, is the only immune cause of hydrops fetalis. Rh disease is a hemolytic disease of newborns. Pregnant mothers do not always have the same blood type as their child. During birth or throughout the pregnancy, the mother may be exposed to the infant's blood.
