Histopathological pattern of Orbito-Ocular Lesions, a retrospective hospital-based study spanning 15 years

Background: Many previous studies on orbito-ocular lesions are skewed in favour of the neoplastic lesions in general and the malignant lesions in particular. This, therefore, creates a vacuum on the spectrum of these lesions, thus may result in problematic diagnostic bias by the ophthalmologist and pathologist. Objective: To give the spectrum and relative frequencies of orbito-ocular biopsies and by extension orbito-ocular lesions/diseases at the University of Benin Teaching Hospital (UBTH). Materials and Methods: A retrospective descriptive study of all cases of orbito-ocular biopsies with histopathologic diagnosis. Results: There were 236 orbito-ocular biopsies. The male to female ratio was slightly in favour of the females. Orbito-ocular biopsies had a wide age range that spanned from the 1st to 10th decade, mean age in the 3rd decade (20-29years) and a peak age in the 1st decade (0-9 years). The neoplastic lesions were the prevalent indication for orbito-ocular biopsies (63.72%) while the conjunctiva (58.10%) was the most common site for orbito-ocular biopsies. Conclusion: This study noted a wide array of orbito-ocular lesions for which biopsies were done for histopathological diagnosis. This we hope will in no small measure increase the diagnostic precision of the ophthalmologist and the pathologists in our own environment

Revision surgery in lumbar degenerative disease

Introduction: Lumbar degenerative disease is a common health problem all over the world and the need for revision surgery is still high with variable results. The aim of the work: Is to evaluate the clinical and radiologic outcome in cases of redo surgery for lumbar degenerative pathology and to specify which pathology is responding well to revision surgery.Patients and methods: Forty eight patients were operated upon for revision of previous failed back surgery in Zagazig University Hospitals from August 2014 to April 2017. Selection of patients for revision surgery depends on confirmed radiological and clinical compression or instability. All patients were operated and followed for at least 6 months after surgery. VAS score was used as a tool for evaluation of back and leg pain.Results: There were 48 patients; with a mean age of 46.7 years (range 22-78).There were 29 males and 19 females. The dominant symptoms were unilateral sciatica in 30, bilateral in 11, low back pain in 23 patients.Neurogenic claudication was present in 4 cases. Type of surgery was redo discectomy in 31 cases, revision decompression for spinal canal stenosis in 4 cases, and posterior lumbar interbody fusion in 13 cases, with success rate of 96.8%, 75% and 84.6% respectively regarding improvement after surgery.Conclusion: Revision surgery of lumbar degenerative diseases gives excellent results provided that the patients are properly selected
