Formaldehyde is an anxious gas used as a tissue preservative of cadavers in anatomy halls. Therefore, laboratory staff and students are at high risk of different clinical complications due to the continuous exposure to formaldehyde. The present questionnaire-based study evaluates the effects of formaldehyde exposure on veterinary students and staff in the anatomy gross dissection laboratory, University of Tripoli, Libya. A total of 104 students and 6 anatomy staff members completed a questionnaire of 24 questions related to the clinical symptoms observed after formaldehyde exposure and the answers were assessed using a six point (0-5) scale. Students had a high prevalence of nasal itching 78(75%), eyes burning 78(75%), excessive lacrimation 76(73%), eyes redness 60(58%), headache 64(62%) and respiratory distress 61(59%). Smoking and wearing glasses or gloves worsened many symptoms while wearing masks minimized other symptoms and male students were more affected than females. All anatomy staff members (100%) reported nasal itching, burning and congestion, eyes burning and redness, excessive lacrimation, cough and respiratory distress and less than that (83%) suffered from mouth dryness, headache, temporary loss of their ability to recognize the smell of formaldehyde and needed a physician assistance after the exposure to formaldehyde. The repeated exposure to formaldehyde in gross anatomy dissection has harmful effects on both students and staff member and finding alternative preservation methods, such as freezing, would be safer than using the formaldehyde. arabic 12 English 74

The forelimb fetlock joint and its bony components are a common site of injury in racing horses. We hypothesized that the variations in relative density of these bones might correspond to their mechanical properties. This study aimed first to identify the relative density of third metacarpal bone (Mc3), proximal phalanx (P1) and proximal sesamoid bones (PSBs) of Thoroughbred race horses. Second, to determine whether there was any difference and/or similarity in the relative density between and within the bones. Bones from right and left forelimbs of 10 horses were collected and prepared by boiling and drying. Dry weight and volume for each bone were measured and the relative density was then calculated. Relative density of Mc3 was substantially greater than the other two bones with a mean of 1.7 ± 0.06. Relative density of P1 and PSBs showed a high similarity especially between P1 and the medial PSBs. Neither the comparisons between right and left sides nor between lateral and medial PSBs showed any significant differences. P1 had the most consistent relative density within right and left sides. Larger relative density in Mc3 and the similarity between P1 and PSBs presume a more important role of the bone mass on their properties than the volume.

Abstract Background: Although bone tumors are common pathologies in companion animals, limited reports describe nasal osteosarcoma (OSA) in cats. Case description: A case of nasal OSA in a local Libyan cat was admitted to the Veterinary Teaching Hospital at the Faculty of Veterinary Medicine, University of Tripoli–Libya, with nasal swelling and discharges and facial deformity. The radiological findings revealed nasal osteolysis with the absence of evidence of lung metastasis. In addition, fungal growth was not identified in microbiological culture. Furthermore, the pathological examination has grossly revealed a destructed nasal bone due to the presence of a tumor mass, with a mucohemorrhagic nasal discharge and absence of metastasis. OSA was confirmed histopathologically. Conclusion: This report presents the clinical, radiological, and pathological findings of a primary nasal OSA in a Libyan cat with no tumor metastasis to other body organs. Keywords: Cat, Nasal cavity, Primary osteosarcoma.
