Some babies have microcephaly because of changes in their genes. The premature fusing of the joints (sutures) between the bony plates that form an infant's skull keeps the brain from growing. What you need to know •Fetal microcephaly can be isolated or be associated with other congenital anomalies •Causes include genetic, chromosomal, infections, exposure to toxins (such as alcohol), metabolic, intrauterine growth restriction, or a normal variant Involvement of the CNS is a hallmark of congenital Toxoplasmainfection. Clinical manifestations of congenital toxoplasmosis are different. Microcephaly is a birth defect in which a baby's head is smaller than expected, compared to babies of the same sex and age. Microcephaly may be genetic. Congenital infections causing microcephaly are known as TORCH infections (Toxoplasmosis, Other infections (Syphilis, Varicella Zoster, Parvovirus B-19), Rubella, Cytomegalovirus (CMV) and Herpes virus). 57 Clinical manifestations of congenital toxoplasmosis consist of retinochoroiditis, hydrocephalus, microcephaly, cerebral calcifications, seizures, psychomotor retardation, organomegaly, jaundice, rash, and fever.

Effect on pregnancy. The Toxoplasma parasite can live in cat feces (poop), water, soil, or certain foods. Congenital toxoplasmosis is a disease that occurs in fetuses infected with Toxoplasma gondii, a protozoan parasite, which is transmitted from mother to fetus. The acronym TORCH stands for the causative pathogens of congenital infections: Toxoplasma gondii. Congenital toxoplasmosis is the consequence of transplacental hematogenous fetal infection by T gondii during primary infection in pregnant women. Infection with T gondii before pregnancy confers little or no risk to the fetus except in women who become infected up to 3 months before conception. Microcephaly has been associated with intellectual disability . Congenital toxoplasmosis can have severe sequelae, including mental retardation, blindness, and epilepsy in infancy or much later in life. Babies with mild microcephaly often don't have problems other than small head size.

Head size is an important measurement to monitor a child's brain growth. Congenital toxoplasmosis is almost exclusively due to a primary maternal infection during pregnancy; however, there are exceptions, including reinfection with a new serotype of T. gondii or reactivation of toxoplasmosis in mothers with severe cell-mediated immunodeficiencies. . Manifestations, if present, are prematurity, intrauterine growth restriction, jaundice, hepatosplenomegaly, myocarditis, pneumonitis, rash, chorioretinitis, hydrocephalus, intracranial calcifications, microcephaly, and seizures. Clinical presentations of these congenital infections overlap significantly, and it is usually impossible to determine the causative agent clinically. The Toxoplasma parasite can live in cat feces (poop), water, soil, or certain foods. Congenital toxoplasmosis. The Zika virus is present in Brazil and other parts of South America, along with Mexico, Central America, and the Caribbean. Microcephaly can occur because a baby's brain has not developed properly during pregnancy or has stopped growing after birth, which results in a smaller head size. 11).

Intrauterine growth restriction (low weight) Hepatosplenomegaly (enlarged liver and spleen) Seizures. Introduction: Microcephaly is a congenital anomaly associated with a wide range of etiological factors such as infections, medications/substances, genetic abnormalities and radiation.

On the contrary, in the newborn, congenital toxoplasmosis can be responsible of hydrocephalus, microcephaly, intracranial calcifications, strabismus, blindness, epilepsy, mental retardation, thrombocytopenia, anemia and chorioretinitis. Sometimes detected at birth, microcephaly usually is the result of the brain developing abnormally in the womb or not growing as it should after birth. Primary infection in an otherwise healthy pregnant woman is asymptomatic in 60% of cases. There is no single definition of microcephaly that is universally used. Toxoplasmosis is an infection caused by a parasite called Toxoplasma gondii. Context: The autosomal recessive form of microcephaly-chorioretinopathy syndrome is a rare genetic condition that is considered to be an important differential diagnosis with congenital toxoplasmosis. Toxoplasmosis is an infection caused by a parasite called Toxoplasma gondii. Teratogenic conditions with microcephaly include congenital rubella, CMV, congenital Zika infection and congenital toxoplasmosis. Objective: Toxoplasmosis, cytomegalovirus (CMV), and Zika virus (ZIKV) are among the common infectious agents that may infect the fetuses vertically. pregnancy.

Physiologically, congenital microcephaly is a disorder of reduced brain size and volume resulting from abnormal fetal development. However, infants with congenital toxoplasmosis have been born to immunocompetent women with prior histories of toxoplasmosis infection and with evidence of prior immunity (38).This can occur when a previously-infected pregnant mother is reinfected with a new and more virulent strain. Congenital infections causing microcephaly are known as TORCH infections (Toxoplasmosis, Other infections (Syphilis, Varicella Zoster, Parvovirus B-19), Rubella, Cytomegalovirus (CMV) and Herpes virus).
