Amniotic constriction band is a rare clinical entity with varied manifestations that range from a combination of congenital malformations to isolated malformations that are unique to each patient. The etiology of this entity remains unknown. Herein, we highlight two cases of amniotic constriction band that presented to our unit with unique clinical characteristics. To the best of our knowledge, an isolated circumferential band of scarring on the face with ocular involvement, as demonstrated by the first case, and a combination of bilateral complete cleft lip and palate with bilateral microphthalmia, auto-amputation of the right thumb, and a constriction band on the left thumb, as demonstrated by the second case, are extremely rare presentations of amniotic constriction band that were not previously reported in the literature and therefore necessitate a special mention...

Constriction of the lower limb by congenital amniotic band has been proposed to explain the development of pseudoarthrosis of tibia and fibula. We report a case of amniotic band syndrome in a preterm infant with pseudoarthrosis of tibia and fibula. Simple release of constriction band with Z-plasty resulted in the growth of mature bone, replacing the pseudoarthrosis and hence did not require surgical amputation. Our case confirms the potential for bone growth in ABS, once the constricting band is released. Early limb preserving surgery with release of the constricting band with an intention to salvage the limb appears appropriate...

The incidence of the craniofacial cleft is rare ranging between 1.43 and 4.85/100,000 births. Tessier number nine cleft being the rarest, there are a few reports of detailed ophthalmologic examinations performed in them. In this study, 1-day-old female neonate delivered by normal vaginal delivery at term, weighing 1480 g presented with right eye dystopia, cleft extending through the lateral third of the upper eyelid, brow ending at the temporal region, conjunctival congestion, clear cornea 10 mm in diameter, normal anterior chamber, pupil 2 mm reactive to light, clear lens, and normal fundus...

Constriction of the lower limb by a congenital amniotic band has been proposed to explain the development of pseudoarthrosis of the tibia and fibula. We report a case of amniotic band syndrome in a preterm female infant with pseudoarthrosis of the tibia and fibula. She was born at 29 weeks of gestation with congenital amniotic bands and was noted to have a severely edematous left foot distal to the constricting band with rudimentary digits. The skin was pink and well perfused with palpable pulses. Radiography demonstrated pseudoarthrosis of the tibia and fibula...

Congenital heart defects are the most common birth defect. The limiting factor in tissue engineering repair strategies is an autologous source of functional cardiomyocytes. Amniotic fluid contains an ideal cell source for prenatal harvest and use in correction of congenital heart defects. This study aims to investigate the potential of amniotic fluid-derived stem cells (AFSC) to undergo non-viral reprogramming into induced pluripotent stem cells (iPSC) followed by growth-factor-free differentiation into functional cardiomyocytes...

INTRODUCTION: Pseudoamniotic band syndrome (PABS) occurs iatrogenically after fetal surgery or amniocentesis due to chorioamniotic membrane separation. Separation of the amnion from the chorion can expand to form fibrous amniotic bands that can envelope fetal limbs or the umbilical cord, with consequences ranging from limb constriction to fetal demise. CASE REPORT: We report a case of bilateral fetal pleural effusions at 27 weeks' gestation treated by bilateral thoracoamniotic shunts...

Background: The multiple banded antigen (MBA), a surface-exposed lipoprotein, is a proposed virulence factor of Ureaplasma spp. We previously demonstrated that the number of Ureaplasma parvum MBA size variants in amniotic fluid was inversely proportional to the severity of chorioamnionitis in experimentally infected pregnant sheep. However, the effect of ureaplasma MBA size variation on inflammation in human pregnancies has not been reported. Methods: Ureaplasmas isolated from the chorioamnion of pregnant women from a previous study (n = 42) were speciated/serotyped and MBA size variation was demonstrated by PCR and western blot...

The obstetrical ultrasound may identify the protrusion of the uterine surface or placental area into the amniotic cavity. The differential diagnosis of this pathology with uterine adhesions, septate uterus, circumvallate placenta, amniotic band or amniotic sheet can be sometimes difficult. The purpose of the pictorial essay is to exemplify the presence of the amniotic sheet and circumvallate placenta in routine obstetrics screening of all trimesters of pregnancy.

We report a case of amniotic band syndrome complicated by constriction bands and marked distal swelling of both lower extremities. Color Doppler interrogation of the right lower extremity revealed complete lack of blood flow below the level of the constriction. Upon fetoscopic survey, the right lower extremity beyond the constriction band appeared dusky red and discolored with desquamation, consistent with a necrotic appearance. The constriction bands were cut in utero using endoshears, thereby allowing restoration of blood flow on postoperative day 1...

OBJECTIVE: Euchromatic variants (EVs) of 8q21.2 are extremely rare chromosomal abnormalities. So, far there have only been two reports on EVs of 8q21.2. Here, we report an 8q21.2 EV detected in cultured amniotic-fluid cells of twins. It was later found to be inherited from the mother, who did not present with abnormal phenotypes. CASE REPORT: A pregnant woman underwent amniocentesis at 16 weeks of gestation because of advanced maternal age. This pregnancy was monozygotic twins conceived naturally...

OBJECTIVE: To explore the application of combined techniques for the prenatal diagnosis of a case with 7q11.23 duplication. METHODS: Amniocentesis was performed in the second trimester for a mother with a high risk suggested by serological prenatal screening. G-banded chromosomal analysis was performed on cultured amniocytes and peripheral blood samples from both parents. DNA from amniotic fluid sample was isolated for a BACs-on-Beads (BoBs) assay. To define the range of duplication, copy number variation was determined with single nucleotide polymorphism array (SNP array, Affymetrix CytoScan 750K) and fluorescence in situ hybridization (FISH) analysis...

Amniotic Band Syndrome (ABS) is a group of congenital malformations that includes the majority of typical constriction rings and limb and digital amputations, together with major craniofacial, thoracic, and abdominal malformations. The syndrome is caused by early rupture of the amniotic sac. Some of the main oral manifestations include micrognathia, hyperdontia, and cleft lip with or without cleft palate, which is present in 14.6% of patients with this syndrome. The purpose of this report was to describe the clinical characteristics and the oral treatment provided to a 6-month-old male patient affected with ABS with cleft lip and palate...

Introduction. Amniotic band syndrome and sequence are a relatively rare condition in which congenital anomalies occur as a result of the adherence and entrapment of fetal parts with coarse fibrous bands of the amniotic membrane. A large percentage of reported cases have an atypical gestational history. The frequency of this obstetric complication is not affected by fetal gender, genetic abnormality, or prenatal infection. Case. A 21-year-old, G1P0 female parturient at 18 weeks and 5 days with a single intrauterine gestation during a routine ultrasound evaluation was noted to have amniotic band sequence...

REVIEW
Emma L Sweeney, Samantha J Dando, Suhas G Kallapur, Christine L Knox
The human Ureaplasma species are the most frequently isolated microorganisms from the amniotic fluid and placentae of women who deliver preterm and are also associated with spontaneous abortions or miscarriages, neonatal respiratory diseases, and chorioamnionitis. Despite the fact that these microorganisms have been habitually found within placentae of pregnancies with chorioamnionitis, the role of Ureaplasma species as a causative agent has not been satisfactorily explained. There is also controversy surrounding their role in disease, particularly as not all women infected with Ureaplasma spp...
