Radiological assessment of the PRF/BMSC efficacy in the treatment of aseptic nonunions: A retrospective study on 90 subjects.

Orthopaedic Pathophysiology and Regenerative Medicine Unit, Department of Complex Orthopaedic-Trauma Pathology Rizzoli Orthopaedic Institute, Bologna, Italy.
Background: Nonunion is a major orthopaedic concern because of treatment difficulty, high costs and devastating effects on the patients' life quality. Therefore, there is interest in the use of bone substitutes and cell-based strategies to augment fracture repair. We aimed to verify if Platelet Rich Fibrin (PRF) added with bone marrow stromal cells (BMSC) was able to improve the reparative process in the aseptic nonunion, and to establish whether it was worthwhile with atrophic nonunion.

Objective: To explore the clinical effectiveness of endoscopic myringoplasty with homoplastic amniotic membrane.
Method: A retrospective study in 43 patients underwent endoscopic myringoplasty with homoplastic amniotic membrane was observed at the wound healing of tympanic membrane perforation and the hearing improve-threshold audiometry in 43 patients after surgery.
Result: The tympanic membrane's perforation healing rate was 95.
Surgical treatment of proximal ulna nonunion.

We reviewed our experience in the surgical treatment of 12 cases of proximal ulna nonunion. The primary injuries were 2 fracture-dislocations of the olecranon, 6 Monteggia lesions and 3 isolated fractures of the proximal ulna. According to the type of primary injury and its anatomical site, the nonunions were classified into 2 groups, considering that the nonunions nearest to the humerus-ulna joint present a more disabling clinical profile and are more difficult to treat: group A (6 patients - nonunion within 5 cm from the olecranon tip of the olecranon) and group B (6 patients - nonunion between 5 and 10 cm from the olecranon tip of the olecranon).

Refract Corneal Surg
August 1992
Department of Ophthalmology, El-Maghraby Eye Hospital, Jeddah, Saudi Arabia.
Background: Opacification of the clear optical zone following radial keratotomy has not been observed before.
Methods And Results: The authors noted the appearance of subepithelial dense white reticular cicatrization in the central area following radial keratotomy in a patient with inactive trachoma and clear cornea. The corneal changes resulted in regression of the surgical effect and decrease in visual acuity.
Variations in corneal wound healing after radial keratotomy: possible insights into mechanisms of clinical complications and refractive effects.

Department of Ophthalmology, University of Texas Southwestern Medical Center, Dallas 75235-9057.
Ultrastructural and histopathologic analysis was performed on three human corneal specimens for variable and complicated refractive outcomes 1-2 years after radial keratotomy. Specimens were obtained immediately postsurgery after microkeratome resection with homoplastic lamellar keratoplasty (two cases) and penetrating keratoplasty (one case) for correction of glare, severe astigmatism, overcorrection, and/or double vision. All three cases showed variability of wound healing and delayed corneal wound healing sites; epithelial retention cysts, and/or absence of stromal scar collagen that was not dependent on the length of time after surgery.
