  ABSTRACT: The tarsal plate is the skeleton support system of the eyelids; therefore, repair during eyelid reconstruction is crucial. Many autogenous graft materials have been proposed for the tarsal reconstruction, such as nasal cartilage, palatal mucosa, upper eyelid tarsus, and auricular cartilage. Nail thickness and shape are similar to the tarsal plate with enough support for the eyelid. It also easily integrates with host tissues. The aim of this experimental study was to macroscopically and histopathologically compare nail xenografts with cartilage autografts when used in eyelid reconstruction in rabbits. In total, 12 New Zealand rabbits were used in the experiment. Full-thickness defect with a 1-cm diameter was created in both upper eyelids. The right upper eyelids were used for cartilage autograft reconstruction, and the left upper eyelids were used for nail xenograft reconstruction. All animals were killed on week 12 after eyelid reconstruction. After the animals were killed, the upper eyelids of the rabbits were resected for macroscopic and histologic analysis. In histologic evaluation, moderate foreign body giant cell formation and moderate histiocytic, neutrophilic, basophilic, and lymphocytic infiltration were observed in both experimental group and control group. In addition, this marked fibrous capsule formation was observed around the nail xenograft, which was absent in the cartilage autograft group. Nail has some advantages such as being cost-effective, being easy to obtain, and having less rejection risk for being composed of dead cells. Nail xenografts can be taken into account instead of cartilage grafts in eyelid reconstruction.

  ABSTRACT: In this study, 105 cases of thyroid lesions were evaluated to assess the role of HBME-1, cytokeratin-19 (CK-19), galectin-3 in distinguishing benign from malignant thyroid lesions. Thirty-seven papillary, 10 follicular, 6 medullary, 1 mixed medullary follicular cell carcinoma, 3 poorly differentiated carcinoma, 18 adenomatous nodular hyperplasia, 30 follicular adenoma cases were included in the study. Immunohistochemical staining was performed with HBME-1, CK-19, galectin-3 on cross-sections derived from selected paraffin blocks. Benign and malignant lesions were compared in terms of intensity, percentage and type of staining with CK-19, HBME-1 and galectin-3, and a statistically significant difference (p < 0.05) was found. The percentage and intensity of staining was higher in malignant lesions. Especially, strong and diffuse expressions of CK19, HBME-1 and galectin-3 were observed in papillary carcinomas. Membranous (luminal) staining was seen more frequently in malignant lesions; cytoplasmic staining in benign lesions. It was concluded that these markers could assist in the diagnosis of thyroid lesions with cellular properties suspicious for the diagnosis of papillary carcinoma and without capsule and vessel invasion. They may be used especially in cases where the follicular variant of papillary carcinoma, follicular adenoma and follicular carcinoma are confused with each other and follicular adenoma cannot be differentiated from follicular carcinoma.
