The aim of this study was to evaluate the diagnostic performance of strain elastography in the assessment of mammary neoplasms. Twenty-three dogs and a total number of 57 mammary neoplasms were ...included in this study. The elasticity score and strain ratio were measured using elastography recordings for comparison of histopathology results in mammary neoplasms. The mean elasticity scores were 1.66±0.15 for the benign neoplasms and 3.33±0.16 for the malignant tumors (P0.05). There was no significant difference found in distinguishing malignant mixed tumors and malignant epithelial tumors (P>0.05). The results of this study showed that, strain elastography is a highly valuable tool in differential diagnosis of mammary neoplasms in bitches.

All of the ewes in this study were synchronized for oestrus by insertion of a progesterone impregnated vaginal sponge for 12 days and administration of 400 IU PMSG at sponge withdrawal. Three methods of service were compared: natural service, artificial insemination (AI) with fresh semen, or AI with frozen semen. Two times of insemination (fixed time AI versus AI at observed oestrus) were compared on the fresh and frozen AI treatments. The absence (control) or use of carazolol (carazolol; 0.5
mg/ewe i.m. 30
min before mating) was the third factor in the design and penetration of the cervix by the insemination pipette was assessed as shallow (<10
mm), middle (10–20
mm) or deep (>20
mm). Natural service ewes were only mated at observed oestrus. Consequently, the factorial design was incomplete and there were a total of 10 treatments each represented by 30 ewes. Natural service resulted in a significantly (
P
<
0.05) higher lambing rate and litter size (86%; 2.0
±
0.05 lambs/ewe) than AI using fresh (65%; 1.6
±
0.1
lambs/ewe) or frozen (40%; 1.4
±
0.14 lambs/ewe) semen. For AI animals the lambing rate and litter size were not significantly different when service was at a fixed time (50%; 1.5
±
0.12
lambs/ewe) or at observed oestrus (56%; 1.5
±
0.12 lambs/ewe). Carazolol did not permit complete cervical penetration in any ewe. Deep penetration of the cervix at AI was achieved in 33% of untreated (control) and 48% of carazolol treated ewes (
P
<
0.05). However, the proportion of ewes in which penetration of the cervix and semen deposition was greater than shallow was similar for control (82%) and carazolol (85%), and lambing rate and litter size were similar for both treatments. Over the three service methods, the lambing rate was 56% for control and 63% for carazolol (NS) and litter size was similar for both treatments. It was concluded that the carazolol treatment used prior to natural mating or AI in this experiment did not improve lambing rate or litter size in Kivircik ewes.
The aim of this study was to evaluate the diagnostic performance of strain elastography in the assessment of mammary neoplasms. Twenty-three dogs and a total number of 57 mammary neoplasms were ...included in this study. The elasticity score and strain ratio were measured using elastography recordings for comparison of histopathology results in mammary neoplasms. The mean elasticity scores were 1.66+ or -0.15 for the benign neoplasms and 3.33+ or -0.16 for the malignant tumors (P<0.001). The optimal cutoff value was found to be between 2 and 3 (2.5), with values of 71.4% sensitivity and 93.3% specificity. The mean strain ratios were calculated 1.85+ or -0.21 for the benign neoplasms and 3.76+ or -0.23 for the malignant tumors (P<0.001). In the analysis of strain ratio measurements, the optimal cutoff value was found to be 2.15 with 90.5% sensitivity and 80.0% specificity. Analyses with both methods of the malignant epithelial tumors in different grade groups were not statistically different (P>0.05). There was no significant difference found in distinguishing malignant mixed tumors and malignant epithelial tumors (P>0.05). The results of this study showed that, strain elastography is a highly valuable tool in differential diagnosis of mammary neoplasms in bitches.

Istrazivanjem su obuhvacena 23 psa i ukupno 57 neoplazmi mlijecne zlijezde. Na elastografskim zapisima izmjereni su faktor cvrstoce (engl. elasticity score) i omjer cvrstoce (engl. strain ratio) radi usporedbe histopatoloskih nalaza kod neoplazmi mlijecne zlijezde. Prosjecna vrijednost faktora cvrstoce bila je 1,66+ or -0,15 za dobrocudne neoplazme i 3,33+ or -0,16 za zlocudne tumore (P<0,001). Optimalna granicna vrijednost bila je izmedu 2 i 3 (2,5), s osjetljivoscu 71,4% i specifcnoscu 93,3%. Prosjecan omjer cvrstoce bio je 1,85+ or -0,21 za dobrocudne neoplazme i 3,76+ or -0,23 za zlocudne tumore (P<0,001). Analiza izmjerenih vrijednosti pokazala je da je optimalna granicna vrijednost 2,15 s osjetljivoscu 90,5% i specifcnoscu 80,0%. Nije bilo statisticki znakovite (P>0,05) razlike medu tim dvjema metodama u analizi zlocudnih epitelnih tumora u razlicitim stadijima, a statisticki znakovite (P>0,05) razlike nije bilo ni izmedu zlocudnih mjesovitih tumora i zlocudnih epitelnih tumora. Rezultati ovog istrazivanja pokazali su da je strain-elastografja izvrstan alat u diferencijalnoj dijagnostici neoplazmi mlijecne zlijezde kuja.

Yapılan çalışmada yedi kısrağa ovarium tümörü sebebiyle inhalasyon anestezisi altında tek taraflı ovariectomy
operasyonu yapıldı. Değerlendirilen tüm kısrakların 2 senelik infertilite geçmişi ...bulunmakta idi. Bu kısraklardan 6 tanesi
kalıcı anöstrus gösteriyorken, bir tanesi kalıcı östrus gösteriyordu. Tümörlerin klinik tanısı rektal palpasyon ve
ovariumların ultrasonografik gözlemi ile yapıldı. Tüm kısraklarda flank yaklaşım tekniği kullanıldı. Tüm kısraklar başarılı
şekilde ameliyat edildi. Kısraklardan bir tanesinde kızgınlığın gecikmesi ve ensizyon hattında abse oluşumu gözlendi. Bir
kısrakta ovariectomy sonrası karşı taraftaki ovarium küçük ve inaktif kaldı. Histopatolojik inceleme sonrasında etkilenen
ovarium için fibrothecoma tanısı kondu. Söz konusu kısrak ovariectomy sonrası infertil kaldı. Diğer kısraklar ameliyat
sonrasında östrus (ortalama: 154 ± 30 gün) gösterdi ve üreme yeteneğine kavuşarak normal davranış gösterdiler. Bu
kısrakların ovariumları için histopatolojik inceleme sonrasında granulosa theca hücre tümörü (GTCT) tanısı kondu.
Kısrakların aşımları için bir sonraki üreme sezonu beklendi. Bu kısraklar çiftleştirilmelerini (ortalama: ameliyat sonrası
296 ± 20 gün) takiben gebe kaldılar ve sorunsuz olarak sağlıklı taylar doğurdular.
Unilateral ovariectomies were performed on 7 mares under inhalation anesthesia for treatment of ovarian
tumors. All mares were evaluated for a 2-year history of infertility; 6 mares showed persistent anestrus while 1 mare
showed persistent estrus. The presumptive clinical diagnosis of the tumors was made by rectal palpation and
ultrasonographic imaging of the ovaries. The affected ovaries were large, spherical, and hard, and the contralateral ovaries
were small and inactive. The flank approach technique was used for all of the mares. All mares were operated on
successfully. One of the mares had delayed healing and abscess formation in the incision line. In one postovariectomy
mare, the contralateral ovary remained small and inactive; the histopathological diagnosis for the ovarian tumor was
fibrothecoma and the mare remained infertile after the ovariectomy. The other 6 mares returned to estrus (average: 154
± 30 days), were capable of breeding, and exhibited normal behavior after the surgery. These mares were diagnosed
histopathologically with ovarian granulosa theca cell tumors (GTCT). These mares were not bred until the next breeding
season. After breeding (average time to successful conception: 296 ± 20 days after surgery), these mares became pregnant
and gave birth to normal foals uneventfully.
