With increase use of tissue-integrated prostheses in recent years it is a goal to understand what is happening at the interface between haversion bone and bulk metal. This study uses electron microscopy (EM) techniques to establish parameters for osseointegration (structure and function between bone and nonload-carrying implants) in an animal model. In the past the interface has been evaluated extensively with light microscopy methods. Today researchers are using the EM for ultrastructural studies of the bone tissue and implant responses to an in vivo environment. Under general anesthesia nine adult mongrel dogs received three Brånemark (Nobelpharma) 3.75 × 7 mm titanium implants surgical placed in their left zygomatic arch. After a one year healing period the animals were injected with a routine bone marker (oxytetracycline), euthanized and perfused via aortic cannulation with 3% glutaraldehyde in 0.1M cacodylate buffer pH 7.2. Implants were retrieved en bloc, harvest radiographs made (Fig. 1), and routinely embedded in plastic. Tissue and implants were cut into 300 micron thick wafers, longitudinally to the implant with an Isomet saw and diamond wafering blade [Beuhler] until the center of the implant was reached.

Introduction: Spinal tuberculosis is the most common manifestation of extrapulmonar y tuberculosis. A combination of leprosy and tuberculosis is a rare entity.Case report: A 44-year-old male patient working as a laborer presented to our hospital with complaints of severe back pain and swelling over the back, difficulty in walking, associated with constitutional symptoms. On admission, he was febrile and had leukocytosis. Initial spine X-ray showed end plate destruction and increase in soft tissue shadow at the level of T8-T9. CT spine revealed thoracic paravertebral collection extending from T7 to T9 levels, suggest ive of tuberculous spondylitis with cold abscess. Patient refused a transpedicular biopsy and was started on anti-tubercular therapy. Two weeks after commencement of treatment, he developed worsening back pain and weakness of the lower extremities. MRI spine showed a paravertebral abscess and posterior soft tissue edema involving level of T7 to T11. Patient underwent a posterior decompression, debridement and posterior instrumentation. He was discharged well, there was improvement of his lower limb power. Upon clinic review, he complained of multiple hyperpigmented, painless, nonpruritic skin lesions over the trunk and back. No previous history of eczema, psoriasis and Tinea corporis. Given the history of allergy, initial impression was hypersensitivity reaction towards the titanium implants, and he was started on anti-histamines. However, there was no improvements seen. Histopathological examination of skin lesions revealed presence of granuloma within the dermis layer, composed of epitheloid, histiocytes, lymphocytes and plasma cells. Wade-Fite stain for Mycobacterium leprae is positive. Slit skin smear shows multibacillary leprosy. Patient was started on multidrug therapy (rifampicin, clofazimine and dapsone) for 1 year. He has recovered well.International Journal of Human and Health Sciences Supplementary Issue: 2019 Page: 33
