Effect of Previous Crosslinking on Intraoperative and Postoperative Outcomes and Complication Rates of Big-Bubble Deep Anterior Lamellar Keratoplasty for Keratoconus: A Comparative Study.

Purpose: To compare surgical outcomes and intraoperative and postoperative complications of big-bubble deep anterior lamellar keratoplasty (DALK) in patients with and without a history of previous corneal collagen crosslinking (CXL) for keratoconus.

Methods: Patients with keratoconus who underwent DALK surgery with big-bubble technique between January 2013 and January 2018 were retrospectively reviewed. Operative findings, intraoperative and postoperative complications, and visual and refractive outcomes were recorded.

Immunohistochemical Grading of Epidural Fibrosis with CD105 Antibody.

Objective: Grading of epidural fibrosis (EF) is usually performed by histopathologic staining in experimental studies. Immunohistochemical methods for grading are not available in routine practice yet. In our study, the effect of tranexamic acid (TXA), a commonly used hemostatic agent in surgical interventions, was evaluated for use against the development of EF with classical histopathologic methods and immunohistochemistry using the CD105 antibody, a marker of angiogenesis.

The assessment of autofluorescence of the crystalline lens in diabetic patients and healthy controls: can it be used as a screening test?

Background: Our purpose was to demonstrate if measuring lens autofluorescence (AF) with a scanning confocal biomicroscope may be used to identify subjects with undiagnosed type II diabetes mellitus (DM), and hence, for it to be used as a marker for the severity of diabetic retinopathy in diabetic patients.

Patients And Methods: In this cross-sectional, comparative study, lens AF was measured with scanning confocal lens fluorescence biomicroscope in diabetic and healthy groups. Full ophthalmological examination was performed.

Epithelioid hemangioendothelioma of the craniocervical junction; case report and review.

Epithelioid hemangioendotheliomas are uncommon vascular neoplasms and their spinal location is even rarer. We report clinical course of a 31-year-old man with an epithelioid hemangioendothelioma at the cranio-cervical junction. A cervical magnetic resonance imaging revealed tumor that caused posterior cervical cord compression.

Anterior cervical fusion with interbody cage containing beta-tricalcium phosphate: Clinical and radiological results.

Aim: Beta tricalcium phosphate (beta-TCP) is an osteoconductive, resorbable material. Its clinical effectiveness has been proved in many indications. This study was clinical and radiographic study report obtained in patients undergoing anterior cervical discectomy and fusion ACDF in which PEEK cages were filled beta-TCP in an injectable form.

Long-term Surgical Outcomes of Spinal Schwannomas: Retrospective Analysis of 49 Consecutive Cases.

Aim: Spinal schwannomas (SS) represent the most common intradural extramedullary lesions, accounting for approximately 24% of all nerve sheath tumors in adults. Schwannomas have infrequent, but existent possibility of malignancy. In this study, long-term outcomes of 49 consecutive SS have been presented.

Management of Tethered Cord Syndrome in Adults: Experience of 23 Cases.

Aim: Tethered cord syndrome (TCS) is rarely diagnosed in adults. It is a complex clinicopathological entity that remains poorly understood. In this study, clinical outcomes of 23 consecutive congenital TCSs diagnosed in adults have been evaluated to establish a standard approach to treat congenital TCS diagnosed in adults.

Non-traumatic myositis ossificans in the lumbar spine.

Background: Myositis ossificans is a non-neoplastic benign reactive bone and cartilage matrix-producing pseudotumor that develops in skeletal muscles adjacent to the joint. The clinical and pathologic appearance of myositis ossificans varies depending on the time elapsed after heterotopic bone formation. Although its etiology is unclear, it usually occurs at the site of the injured muscle, most commonly in large muscles of the extremities, especially the quadriceps and brachialis.

Solitary osteochondroma arising from cervical spina bifida occulta.

Solitary osteochondromas are common benign long bone tumors originating from cartilage. They may produce a wide variety of symptoms and complications depending on their spinal location. These may include compressive myelopathy, nerve root compression, pathologic fracture and malignant degeneration, or in some cases only pain.

Cerebellar Mutism Syndrome After Posterior Fossa Surgery: A Report of Two Cases of Pilocytic Astrocytoma.

Cerebellar mutism is a type of syndrome including decreased speech, hypotonia, ataxia and emotional instability which occurs after posterior fossa surgery. It has been first reported by Rekate et al. and Yonemasu in 1985.

Penetrating keratoplasty versus deep anterior lamellar keratoplasty: comparison of optical and visual quality outcomes.

Purpose: To evaluate and compare visual and optical performance outcomes by means of analysis of the contrast sensitivity function (CSF) and ocular higher order aberrations (HOA) in patients with keratoconus who had deep anterior lamellar keratoplasty (DALK) or penetrating keratoplasty (PK).

Methods: In this prospective, randomised case series, 174 eyes of 140 consecutive patients with moderate to advanced keratoconus were included. The big-bubble technique was attempted to perform DALK.

The first Anatolian contribution to treatment of sciatica by Serefeddin Sabuncuoglu in the 15th century.

Serefeddin Sabuncuoglu was an early 15th century surgeon in Anatolia. His masterpiece entitled Cerrahiyetül Haniye (Imperial Surgery) is the first illustrated surgical textbook in the Turkish Islamic literature of the Ottoman era Anatolia. It is the first written medical-surgical work in Anatolian history and it covers the treatment of more than 40 illnesses, which range from hydrocephalus to sciatica.
