Item Accuracy of ultrasonography in detecting fragmentation of the medial coronoid process in dogs(Amer Veterinary Medical Assoc, 2009-02-15) Michele, Ursula; Tacke, Sabine; Kramer, Martin; Gerwing, Martin; Seyrek, Deniz İntaş; Uludağ Üniversitesi/Veteriner Fakültesi/Doğum ve Jinekoloji Anabilim Dalı.; 6506990178Objective-To determine the accuracy of ultrasonography in detecting fragmentation of the medial coronoid process (FMCP) in dogs. Design-Cross-sectional study. Animals-102 dogs (112 elbow joints) suspected to have FMCP Procedures-Elbows were examined ultrasonographically prior to surgery for evidence of fragmentation, fissuring, or deformation of the medial coronoid process; thickening of the joint capsule; joint effusion; and secondary new bone formation. Results were compared with intraoperative findings. Results-At surgery, 51 (46%) joints had free fragments, 55 (49%) had nondisplaced fragments, and 6 (5%) did not have any fragments or fissures. Fragments were not seen ultrasonographically in 23 of the 51 (45%) joints in which a free fragment was found during surgery or in 50 of the 55 (91%) joints in which a nondisplaced fragment was found during surgery. Accuracy of using ultrasonographic evidence of any medial coronoid process abnormality (ie, a medial coronoid process fragment, deformation of the medial coronoid process, or both) for diagnosis of medial coronoid process fragmentation was 77%. The kappa coefficient for the level of agreement between ultrasonographic (ie, any medial coronoid process abnormality) and surgical findings was -0.014, indicating that there was no agreement. Conclusions and Clinical Relevance-Results suggested that ultrasonography was of limited diagnostic value in detecting FMCP in dogs.Item Evaluation of thoracic trauma in dogs and cats: A review of seventeen cases(Shiraz University, 2010) Kramer, Martin; Salcı, Hakan; Bayram, Ahmet Sami; Çelimli, Nureddin; Çalışkan, Gülsüm Ülke; Görgül, Osman Sacit; Uludağ Üniversitesi/Veterinerlik Fakültesi/Klinik Bilimler Bölümü.; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Cerrahisi Anabilim Dalı.; 0000-0002-4542-315X; T-4623-2019; ABB-7580-2020; 8680329000; 8347194000; 8680328800; 24334005700; 6507730974The objective of this study was to assess the etiology, diagnosis, treatment methods, surgical findings, postoperative results and necropsy findings of seventeen cases of thoracic trauma by evaluating medical records. A car accident, falling down, stabbing and bites were identified as the causes of trauma. Diagnosed pathologies in the cases included pneumothorax, hemothorax, pulmonary contusion, lung lobe collapse or eventration, rib fractures, etc. The treatment methods employed in these cases were medical therapy, thoracocentesis, tube thoracostomy, lateral intercostal thoracotomy, median sternotomy and thoracic wall revisions. Atelectasis, rupture, laceration or contusion of the lung lobes, pulmonary artery rupture, rib fracture and etc. were the surgical findings. Overall, seven dogs and four cats recovered completely. Two dogs were euthanized due to other pathologies including multisegmental lumbar fracture, paraplegia and postpneumonectomy syndrome. Three dogs and a cat died during treatment management. The necropsies revealed that the animals had pulmonary artery and tracheobronchial ruptures. The cat also had sudden onset cardiac arrest during surgery. In conclusion, cases with thoracic trauma should be assessed closely and managed with the necessary emergency and surgical procedures.Item Radiographic pelvimetry and evaluation of radiographic findings of the pelvis in cats with dystocia(George Thieme Verleg KG, 2008) Kramer, Martin; Celimli, Nureddin; İntaş, Deniz Seyrek; Yılmazbaş, Gülnaz Mecitoğlu; İntaş, Kamil Seyrek; Keskin, Abdülkadir; Kumru, İsmail Hakki; Uludağ Üniversitesi/Veterinerlik Fakültesi/Kadın Hastalıkları ve Doğum Anabilim Dalı.; Uludağ Üniversitesi/Veterinerlik Fakültesi/Klinikleri.; Uludağ Üniversitesi/Veterinerlik Fakültesi/Cerrahi Bölümü.; Uludağ Üniversitesi/Veterinerlik Fakültesi/Radyoloji Bölümü.; 0000-0003-2817-3221; O-9153-2019; AAH-3831-2021; AAG-4440-2019; AAH-7292-2019; 8680328800; 24759148000; 36457964000; 24759183100; 24473229800; 16637505700Objective: The aim of this study was to determine reference values for pelvic dimensions in radiographically unremarkable native Turkish cats (similar to European Shorthair cats) and to evaluate radiographic findings of the pelvis in cats with dystocia and to compare their pelvimetric measurements with those of radiographically unremarkable cats. Material and methods: Pelvinnetry was performed on ventro-dorsal and lateral radiographs of radiographically unremarkable male (n = 34) and female cats (n = 23) with no history of dystocia and cats presented with dystocia. Cats with dystocia were classified in groups according to radiographical findings: cats without obvious radiographical changes, cats with traumatic pelvic stenosis and cats with pelvic narrowing due to metabolic disease. Statistical analyses were performed to find out significant differences between both groups with respect to gender and age. Results: Pelvic dimensions of radiographically unremarkable cats are greater in males compared to females. These differences increase with increasing age, but are not significant in cats older than 2 years. Twenty-five out of 37 queens presented with dystocia had significantly smaller pelvic dimensions compared to radiographically unremarkable queens. Deformation/narrowing of the pelvis in 12 cats (32%) due to old fractures and metabolic bone disease occurred in 7 and 5 cases, respectively. Conclusion: Old, untreated pelvic fractures and metabolic disorders may cause stenosis of the birth canal and dystocia. However, there is a high rate of queens without deformation, but smaller pelvic dimension experiencing dystocia. As 80% of these cats are around 1 year of age they might still be growing or are underdeveloped, despite pelvic physeal growth plates are already closed. Clinical relevance: Pelvic radiographs and pelvimetry before mating enables to identify cats with pelvic narrowing due to traumatic, metabolic, or developmental reasons and may prevent the queen from potential dystocia.Item Sonography of the kidneys, urethra and adrenal gland: Position, standard cut level, normal anatomy, pathology(Schluetersche, 2009-07-01) Gerwing, Martin; Kramer, Martin; İntaş, Deniz Seyrek; Uludağ Üniversitesi/Veterinerlik Fakültesi/Doğum & Jinekoloji Anabilim Dalı.Item Sonography of the prostate gland and testicles: Position, standard cutting planes, normal anatomy and pathology(Schluetersche Verlagsgesellschaft, 2010-06-01) Cerwing, Martin; Kramer, Martin; Seyrek, Deniz İntaş; Uludağ Üniversitesi/Veterinerlik Fakültesi/Hayvan Hastanesi.; 6506990178Item Ultrasonographic diagnosis of intestinal mural changes in the cat(Georg Thime Verlag, 2008) Peppler, Christine; Marek, Nadine; Gerwing, Martin; Kramer, Martin; Seyrek İntaş, Deniz; Uludağ Üniversitesi/Veteriner Fakültesi/Radyoloji Anabilim Dalı.; 6506990178Objective: The aim of this study was to characterize ultrasonographically detectable mural changes in cats with intestinal disorders and to determine their diagnostic relevance. Material and methods: Ultrasonographical examination was performed between 2002-2005 in 30 cats with non-specific gastro-intestinal symptoms. Alterations of the thickness, layering and echogenicity of the intestinal wall, symmetry and dimensions of the lesion if present, and involvement of abdominal lymph nodes were evaluated. Tissue specimens were collected for histopathologic examination by ultrasound-guided 18-gauge tru-cut biopsy or full-thickness biopsy via laparotomy. Results: Sonographic evaluation of 30 cats revealed a separate thickening of the muscular layer (n = 14) and a symmetric (n = 10) or asymmetric (n = 6) thickening of the entire intestinal wall. Further sonographical findings of the abdomen were enlarged lymph nodes, free fluid and oedema of the mesentery, or additional lesions in other organs. Histopathologically, 12 cats had benign inflammatory disorders, 13 cats had alimentary lymphoma, four cats had adenocarcinoma, and in one case the intestinal tract was histologically normal. Conclusions: Increased thickness of the muscularis propria maintaining normal mural layering occurs more frequently during intestinal inflammation (10 of 12 cases), while neoplastic alterations more often show a symmetric or asymmetric thickening of the entire bowel wall. Clinical relevance: Diagnostic ultrasonography is an important tool for the detection of mural alterations of the intestinal tract in the cat. The definite diagnosis must be made histopathologically.Item Ultrasonography in disorders of the urinary tract of dogs and cats(George Thieme, 2011) Karpenstein, Heike; Klumpp, Stephan W.; Kramer, Martin; İntaş, Deniz Seyrek; Uludağ Üniversitesi/Veterinerlik Fakültesi/Cerrahi Anabilim Dalı.; 6506990178
