Background: Adhesions after tendinopathy in individuals who perform physical work and those physically active in middle age are a challenging problem for orthopedic surgeons. We evaluated the effects of human-derivated amniotic membrane on tendon healing, adhesions, angiogenesis, and the inflammatory process.
Methods: Thirty-five rats were divided evenly into five groups, and the left lower extremity was used in this study. No interventions were applied to the control group (group 5). In the other groups, Achilles tendons were partially cut to the midline. Then, primary repair (group 1), amniotic membrane treatment with no repair (group 2), primary repair and amniotic membrane treatment (group 3), or secondary healing with no repair (group 4) was performed.
Results: Use of amniotic membrane in tendon healing resulted in decreased adhesion formation and positive effects on collagen sequencing and anti-inflammatory effects. In addition, for the vascular endothelial growth factor evaluation there was no difference among the amniotic membrane repair groups, but there was an increase in vascular endothelial growth factor positivity compared with the control group.
Conclusions: These data show that amniotic membrane treatment can alter biological behavior and induce surface-dependent angiogenesis and can have angiogenetic effects on ischemia and inflammation.

Oral squamous cell papilloma is a benign proliferation of the stratified squamous epithelium, associated with the human papillomavirus (HPV). The clinical manifestation includes papillary or verrucous exophytic mass. Complete excision of the lesion, including normal margins, followed by histopathological examination is the treatment of choice.

We report a case of sympathetic ophthalmia that developed in the fellow eye following therapeutic corneal transplantation and amniotic membrane transplantation for corneal perforation caused by corneal ulceration. A 62-year-old man presented with discharge, lacrimation, and decreased visual acuity in the left eye. He was diagnosed with a corneal ulcer and treated with antimicrobial agents, but corneal epithelial erosion persisted, leading to nontraumatic corneal perforation.

Aim: Maternal colonization by Enterobacteriaceae that produce extended-spectrum β-lactamases (ESBL-E) has risen, and the antimicrobial resistance of ESBL-E is significant. We aimed to evaluate the rates of ESBL-E colonization among women with preterm premature rupture of membranes (PPROM) and of maternal-neonatal vertical transmission. We also aimed to compare obstetrical and neonatal complications among ESBL-E positive versus negative maternal colonization in pregnancies complicated by PPROM.

We describe a novel technique for recurrent pterygium and assess the advantage of properties of extended tenonectomy, amniotic membrane transplantation, and limbal epithelial transplantation in terms of recurrence rate, postoperative symptoms, postoperative orthoptics, and other complications. A total of nine eyes with recurrent pterygium underwent PERMISLET, i.e.

The dehydrated human amnion-chorion membranes (dHACMs) derived from the human placenta have emerged as a promising biomaterial for dental pulp regeneration owing to their unique biological and structural properties. The purpose of this review is to explore the potentials of dHACMs in dental pulp tissue engineering, focusing on their ability to promote cellular proliferation, differentiation, angiogenesis, and neurogenesis. dHACMs are rich in extracellular matrix proteins and growth factors such as TGF-β1, FGF2, and VEGF.
