Amniotic membran

A Schilimow, B Wiechens
In this article, a case of recurrent epithelial defects in neurotrophic keratopathy is described. Multiple abrasions of the corneal epithelium with a therapeutic contact lens, corneal stitches, and amniotic membrane transplantation in combination with artificial tears brought only short-term success. However, a botulinum toxin A induced protective ptosis could finally achieve permanent epithelial closure. As this case shows, protective ptosis can be a promising approach in spite of multiple previous ineffective therapeutic efforts...

A 54-year-old male developed symptomatic scleral buckle exposure 16 years after placement and presented with large conjunctival defects with fibrosed edges. Following surgical removal of the buckle elements, primary conjunctival closure could not be achieved due to significant wound tension despite undermining the conjunctival edges to mobilize the conjunctiva. A dehydrated amniotic membrane graft (Ambio5; IOP Ophthalmics, Costa Mesa, CA) was placed on the scleral bed and secured in place with fibrin sealant (TISSEEL; Baxter International, Westlake Village, CA)...

OBJECTIVE: Bronchopulmonary dysplasia (BPD) is a serious complication associated with preterm birth. A growing body of evidence suggests a role for prenatal factors in its pathogenesis. Metabolomics allows simultaneous characterization of low molecular weight compounds and may provide a picture of such a complex condition. The aim of this study was to evaluate whether an unbiased metabolomic analysis of amniotic fluid (AF) can be used to investigate the risk of spontaneous preterm delivery (PTD) and BPD development in the offspring...

BACKGROUND: Chorioamniotic membrane separation (CMS) is a rare finding that is commonly preceded by invasive fetal procedures. The presence of CMS can also be associated with uncommon maternal or fetal conditions as well as preterm delivery, amniotic band syndrome, umbilical cord complications, and fetal and neonatal death. It is classified as a high-risk antepartum condition due to the significant fetal morbidity and mortality that may ensue. CASE REPORT: A 40-year-old gravida 5 para 1212 at 35 weeks presented for antepartum fetal testing...

In dogs, there is no diagnostic test to identify and differentiate fetal fluids from maternal urine in the event that a clear-yellowish vulvar discharge is observed pre-whelping. The objective of this study was to find a test that could easily and accurately identify rupture of the fetal membranes preceding parturition. Maternal urine, and amniotic fluid (AMF) and allantoic fluid (ALF) from only one fetus per bitch, were collected intraoperatively during cesarean section. Specific gravity (SG) was analyzed with a refractometer, whereas the presence of leukocytes, protein, glucose, ketones, bilirubin, urobilinogen, nitrite, erythrocyte/hemoglobin (Hb), and the pH were assessed using a urine dipstick (Combur-Test)...

OBJECTIVE: These case series present a retrospective analysis of clinical effects that an allogeneic amniotic cell transplantation can have in treating 4 patients with type 2 diabetes. PATIENTS AND METHODS: Eligible diabetic patients were onset within 3 years, with fasting blood glucose > 7.0 mmol/l. Stem - cells that are collected from neonatal amniotic membrane when a child is born (2 x 107 cells) - are used for the treatment of these patients. Measured by the flow cytometry, stem cells transfer clusters of differentiation CD113 and CD34 at a high level, and through the femoral artery on the left, they are administered into the patient's pancreatic dorsal artery...

PURPOSE: To evaluate the effect of prolonged limbal explants cultured without any scaffolds or on amniotic membrane (AM) on the viability, proliferation and differentiation potential of putative phenotypically defined cultured limbal mesenchymal (LMSC) and epithelial stem cells (LESC). METHODS: Limbal explants were cultivated on cryopreserved intact AM or plastic plates using medium supplemented with only human serum. AM was positioned with either the epithelial or stromal side up...

Pemphigoid and pemphigus diseases as well as Stevens-Johnson syndrome present as vesiculobullous disorders of the skin and may additionally involve both the oral cavity and the ocular surface. Ocular involvement ranges from mild irritation and dry eye disease to chronic conjunctivitis, symblepharon, eyelid malposition, ocular surface scarring and severe visual loss. In addition to diagnostic assessments, ophthalmologists must treat the dry eye and Meibomian gland dysfunction components of these diseases using a stepladder approach, including eyelid hygiene and lubricants...

Osteoarthritis (OA) is a progressive degenerative joint disease and to date, no disease modifying osteoarthritis drug exist. Amniotic membrane and umbilical cord products have been used clinically in several diseases due to their anti-inflammatory and anti-scarring properties. In the present study, we sought to evaluate whether a particulate amniotic membrane and umbilical cord (AM/UC) matrix could aid in attenuating disease progression. Lewis rats underwent medial meniscus transection (MMT) to induce OA. Two weeks after surgery, animals received intra-articular injections (50 μL) of either 50 µg/µL or 100 µg/µL particulate AM/UC or saline control and were subsequently euthanized 1 or 4 weeks later...

Patients with limbal stem cell deficiency (LSCD) often experience pain and photophobia due to recurrent epithelial defects and chronic inflammation of the cornea. Successfully restoring a healthy corneal surface in these patients by transplantation of ex vivo expanded human limbal epithelial cells (LECs) may alleviate these symptoms and significantly improve their quality of life. The clinical outcome of transplantation is known to be influenced by the quality of transplanted cells. Presently, several different protocols for cultivation and transplantation of LECs are in use...

Body stalk anomaly (BSA) and amniotic band syndrome (ABS) are rare similar fetal sporadic polymalformative syndromes of unknown etiology, though there are certain differences between them. BSA is a combination of developmental abnormalities involving neural tube, body wall, and the limbs with persistent extra embryonic coelomic cavity. ABS is characterized by the presence of thin membrane-like strands attached to fetal body parts and causing constrictions and amputations. This is a cohort study involving 32,100 patients who were referred for routine antenatal ultrasound scan...

Human leukocyte antigen-G (HLA-G) is a nonclassical HLA class I antigen that is expressed during pregnancy contributing to maternal-fetal tolerance. HLA-G can be expressed as membrane-bound and soluble forms. HLA-G expression increases strongly during viral infections such as congenital human cytomegalovirus (HCMV) infections, with functional consequences in immunoregulation. In this work we investigated the expression of soluble (s)HLA-G and beta-2 microglobulin (component of HLA) molecules in correlation with the risk of transmission and severity of congenital HCMV infection...

The cornea is a self-renewing tissue located at the front of the eye. Its transparency is essential for allowing light to focus onto the retina for visual perception. The continuous renewal of corneal epithelium is supported by limbal stem cells (LSCs) which are located in the border region between conjunctiva and cornea known as the limbus. Ex vivo expansion of LSCs has been successfully applied in the last two decades to treat patients with limbal stem cell deficiency (LSCD). Various methods have been used for their expansion, yet the most widely used culture media contains a number of ingredients derived from animal sources which may compromise the safety profile of human LSC transplantation...

PURPOSE: Gal-3, which can regulate immune responses upon infection and inflammation, was not studied so far in intrauterine infection leading to pre-term pre-labor rupture of the membranes (PPROM), although gal-1 was reported to be implicated in the process. Gal-3 mRNA and protein expression in amnion and its changes during histological chorioamnionitis were studied here. MATERIALS AND METHODS: Fetal membranes were obtained from women with PPROM with (n =15) and without histological chorioamnionitis (n =15) during second and third trimester...

Amniotic fluid embolism (AFE) is a rare, catastrophic emergency that requires prompt recognition and treatment. Despite early recognition and supportive therapy, the morbidity and mortality remain high. We report a case of AFE after vacuum-assisted vaginal delivery resulting in hemodynamic collapse and subsequent multiorgan failure. Management included mechanical ventilation, extracorporeal membrane oxygenation, and continuous veno-venous hemodialysis. The patient was able to make a full recovery with minimal sequelae...

OBJECTIVES: Amniopatch is a proposed treatment of iatrogenic preterm premature rupture of membranes (iPPROM). We studied characteristics associated with successful amniopatch treatment of iPPROM after fetoscopic laser surgery for twin-twin transfusion syndrome. METHODS: Patients with iPPROM within 15 days of laser surgery treated with an amniopatch were studied. Factors associated with amniopatch success (i.e. cessation of leakage with normalization of amniotic fluid volume) were tested univariately and in multivariate logistic regression models...

OBJECTIVE: Cryopreserved amniotic suspension allograft (CASA) is a regenerative tissue suspension containing amniotic membrane and amniotic fluid components used for soft-tissue repair, replacement, and reconstruction. The aim of this case series is to examine its effects in different wound types. METHOD: In a retrospective series CASA was applied to chronic non-healing wounds. All patients were treated at a single center between June 2013 and December 2014. The criterion for application of CASA was lack of progress toward wound healing despite standard treatments and adjuvant therapies...
