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.

Objective: Metacarpophalangeal joint (MCPJ) radiographic parameters were developed to evaluate MCPJ conformation of equine forelimbs, but the effect of joint rotation during radiography on these parameters has not been reported. The current study examined the effect of the rotation around the vertical axis of MCPJ on 27 MCPJ parameters (12 angles and 15 ratios) and identified the acceptable range of rotation at which minimal amount of changes occurred in these parameters. Design: Descriptive study Animals: MCPJs of seven right forelimbs from seven different horses with no MCPJ abnormalities. Procedures: MCPJs of seven right equine forelimbs were loaded in a load cell to obtain the normal MCPJ angle. They were frozen at −20C° and then scanned using a CT-scan machine. The collected slices were reconstructed to obtain a 3D model of MCPJs, and the dorsopalmar view at zero angle (ZDP) were identified. The view was then rotated around the vertical axis of MCPJ. Snapshots were taken for MCPJ at −10°, −5°, Zero, +5° and +10° angles. All the parameters were measured on the total 35 radiographs and statistically analysed. Differences were estimated per 5° of MCPJ rotation for all the parameters. Results:Generally, the ratio parameters were less affected than the angular parameters during MCPJ rotation. Conclusion and clinical relevance: Rotational angles of vertical ±10° from ZDP were considered as an acceptable range for reliable radiographic measurements of MCPJ parameters.

As little is known about the blood profile of camels in Libya, this article is the third of a 4-part series describing the biochemical and haematological blood profile in Libyan camels. In part 1 of these manuscripts, the overall blood biochemical and haematological mean values of camels in Libya were determined, parts 2-4 evaluate the effects of breed, gender and age respectively on these values. Blood samples were collected from 24 male and 42 female apparently healthy camels and the levels of enzymes, metabolites, electrolytes and haematological indices were measured. The blood of the male camels showed higher values of aspartate aminotransferase (AST), Lactate dehydrogenase (LDH), Amylase (AMS), total proteins, globulin and Phosphorus (Ph), than the female camels which showed higher values of glucose, Albumin/Globulin (A/G) ratio, urea, Iron (Fe), Calcium (Ca), Packed Cell volume (PCV), Haemoglobin (Hb), erythrocyte osmotic fragility, Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), neutrophil and monocyte numbers. This study shows significant sex differences between male and female Libyan camels in many haematological and biochemical analytes. arabic 28 English 141
