Eyelid tumors in dogs: 47 cases retrospective study (2006-2017)

Çalışmada 2006-2017 yılları arasında İstanbul Üniversitesi Veteriner Fakültesi Cerrahi Anabilim Dalı Kliniği’ne göz kapağında kitle şikayeti ile getirilen ve sağaltımları yapılan toplam 47 köpeğe ait göz kapağı tümörleri olguları retrospektif olarak değerlendirildi. Olguların ayrıntılı göz muayenesi yapıldı. Kitlelerin uzaklaştırılmasında V şeklinde eksizyon yeğlenerek, tümör tam katlı olarak bölgeden uzaklaştırıldı. Yapılan histopatolojik inceleme sonucu, meibomian bezlerden köken alan neoplazmaların çoğunlukta olduğu belirlendi. Çalışma sonunda elde edilen veriler ile göz kapağı tümörü oluşumunda ırk predispozisyonu, yaşın ve cinsiyetin etkisi ile en yaygın görülen göz kapağı tümörü belirlenip, kullanılan cerrahi yöntemin rekonstruktif blefaroplastiye gerek kalmadan, kitlelerin uzaklaştırılmasında yeterli olduğu görüldü.In this study, the eyelid tumors and the treatment results of 47 dogs referred to Istanbul University Faculty of Veterinary Medicine Department of Surgery with a complaint of eyelid masses were evaluated retrospectively. Cases underwent detailed ophtalmic examination. A V-shaped excision was performed and the tumor was removed in full-thickness. Histopathological examination revealed that most of the neoplasms originating from the meibomian glands were observed. The most common eyelid tumors and formation of the eyelid tumors with respect to the race predisposition, and effects of age and sex were defined. The surgical method used were sufficient for removal of the masses without the necessity of a reconstructive blepharoplasty

Kalça Displazisinde Tanı ve Tedavi Seçenekleri

Köpeklerde kalça displazisi eklem instabilitesi ve osteoartritle karakterize kompleks bir genetik rahatsızlıktır, büyük ve dev ırk köpeklerde daha çok gözlenir. Kalça displazisi genlerinin ekspresyonu, gıda tüketimi, vücut ağırlığı, yaş, hormonlar ve egzersiz gibi birçok çevresel faktörden etkilenir. Kalça displazisinin en önemli nedeni, femur başının asetabulum dışına sublukse olmasıyla karakterize, kalça ekleminin aşırı laksitesi olarak ifade edilebilir. Anamnez, klinik muayene ve fiziksel muayene bulgularına göre tahmini bir tanı konulabilirse de, radyografi hala kalça displazinin tanısında kullanılan primer tanı aracı olma özelliğini muhafaza etmektedir. Köpeklere OFA tarafından normal kalça yapısına sahip olduğuna dair sertifika verilebilmesi için 2 yaşından büyük olmaları gerekir. Diğer yandan üreticiler ellerinde tutacakları köpekleri daha genç yaşta seçmek zorunda olduklarından, veteriner hekimler zor bir durumla yüzleşmek zorunda kalırlar. Diğer yandan tedavide konservatif, medikal ya da cerrahi yöntemlerden hangisinin seçileceğine karar vermek diğer bir tartışmalı konudur. Anahtar Kelimeler: Kalça displazisi, köpek; tan

Evaluation of the stance phases of warmblood sport horses on soft and hard surfaces by infrared optical sensors

The aim of the study was to assertain the differences in walking time of sport horses by investigating their stance phases on soft versus hard surfaces using infrared sensors. A total of 15 warmblood sport horses were used in the study. Three different stages of the stance phase were examined, including initial contact, foot flat and propulsion, alongside assessment of walking pace and step-length. It was observed that the horses were inclined to walk more slowly on soft surfaces compared to hard ground. The amount of time spent in the foot flat position constituted the majority of the stance phase on both surfaces. Propulsion length during the stance phase was shorter on soft surfaces in comparison to hard ground. While the ratio of contact length in forelimbs was lower on hard ground compared to soft surfaces, in hind limbs this ratio was higher on hard ground. Objective data obtained through gait analysis systems are thought to serve as a potential auxiliary diagnostic tool in diseases associated with the locomotor system manifested by lameness, particularly in equine veterinary medicine. In the future, the relevant systems that could offer rapid results through current technology are anticipated to provide accurate preliminary assumptions to evaluate the potential of horses regarding their walking, trotting, and leaping capacity before competitions through such studies

Evaluation of Surgical Treatment Using PRF Membrane in Deep Corneal Ulcers Accompanied by a Descemetocele in Cats: Retrospective Study (2019-2021)

In the present study, the results of the new generation platelet-rich fibrin (PRF) membrane graft application in deep corneal ulcers accompanying descemetocele in cats in ocular surface reconstruction surgery were evaluated, and a retrospective non-comparative study covering the period between May 2019 and August 2021 was conducted. Patients underwent routine surgical procedures for corneal ulcers, and then a new-generation autologous PRF membrane graft was transplanted to the ulcer site. Nineteen eyes were analyzed (14 males, five females). Corneal integrity and vision were achieved in all cases aft er treatment. No signs of infection and infl ammation were noted aft er membrane transplantation. The PRF membrane was transplanted to the defected area with sutures generating highly eff ective results in eliminating the defect's urgency, supporting the cornea, and accelerating the corneal healing. Corneal integration of the PRF membrane was successful in all cases without postoperative separation or stretching. In conclusion, the PRF membrane graft ing was safely and eff ectively utilized in the surgical treatment of deep corneal ulcers in cats with a success rate of 89.4% in descemetocele cases
