THE EFFECT OF SOME ENVIRONMENTAL FACTORS ON MILK COMPOSITION OF ANATOLIAN BUFFALOES

WOS: 000413672900011The aim of this study was to determine the composition of raw milk from Anatolian water buffaloes raised under different village conditions in the Tokat province of Northern Turkey. The study materials included 600 milk samples from 120 water buffaloes raised at different farms in 12 separate villages of the Erbaa, Turhal, and Pazar counties in the Tokat Province. The dry matter, nonfat dry matter (or solid non fat), fat, protein, lactose, and casein content of the milk samples were determined. The study results demonstrated that the mean dry matter, nonfat dry matter, fat, protein, lactose, and casein content of the raw milk samples were 16.99 +/- 0.108%, 10.88 +/- 0.036%, 5.98 +/- 0.107%, 4.85 +/- 0.043%, 5.17 +/- 0,021%, and 3.61 +/- 0.036%, respectively. The study data were evaluated according to the water buffaloes' lactation stage, parity, and season by using the SPSS statistical program. It was concluded that the sampling time, parity, village conditions, stage of lactation and calving age had a significant effect (p < 0.05) on the dry matter, nonfat dry matter, fat, protein, lactose, and casein content of raw milk from the Anatolian water buffalo.Ahi Evran University Scientific Research Projects Coordination UnitAhi Evran University [ZRT.E2.16.008]; General Directorate of Agricultural Research and Policies in Tokat provinceThis work was supported by the Ahi Evran University Scientific Research Projects Coordination Unit.

On the karyology, morphology and biology of Chionomys gud (Satunin, 1909) (Mammalia: Rodentia) in Turkey

WOS: 000266997900014We examined the karyotype of Chionomys gud for the first time from Turkey, and found the values 2n=54, NF=58 and NFa=54. The X chromosome was found to be submetacentric and the Y chromosome acrocentric. Counts of embryos suggested a litter size range of 4 - 6 (mean 4.66, N = 3). Glans penis was stick shaped and covered by numerous microscopic papillae. The baculum had a well developed cartilaginous trifit distal process. The stalk of baculum had a well developed and broad base. The base and the shaft of the os baculum were roughly triangular in shape in dorsal view. The skull shapes of young, adult and aged specimens had distinctive features; in particular, the sagital crest became more prominent in older animals. Much variation was found in the shape of the molar chewing surfaces

Spontaneous Retrobulbar Haematoma

Background. Spontaneous orbital haemorrhage is a very rare condition and vision-threatening event. It may occur due to trauma, orbital surgery/injections, orbital vascular anomalies, and a variety of systemic predisposing factors. Signs of retrobulbar hemorrhage include proptosis, ophthalmoplegia, increased intraocular pressure, loss of pupillary reflexes, and optic disc or retinal pallor. Both Computed Tomography scan and Magnetic Resonance Imaging may be performed in the diagnosis. Case Report. A 31-year-old woman was referred to our hospital with a complaint of headache and blurred vision following a strong sneeze. Ophthalmological examination revealed mild Relative Afferent Pupillary Defect in left eye. Computed Tomography revealed left hyperdense retrobulbar mass and displaced optic nerve. T1 weighted hypointense, T2 weighted hyperintense and non-enhanced round shape, sharply demarcated lesion measuring 18 × 15 × 14 × mm in diameter compatible with haematoma was detected by MRI. Surgically Caldwell-Luc procedure was performed. Histological examination confirmed haematoma. Follow-up Magnetic Resonance Imaging revealed a small reduction in the size of lesion but not complete resolution. The patient’s complaint was regressed. She is now free of symptoms and is still under surveillance. To our knowledge, this is the first reported case of retrobulbar haematoma caused by sneeze

The role of FOXL2, SOX9, and beta-catenin expression and DICER1 mutation in differentiating sex cord tumor with annular tubules from other sex cord tumors of the ovary

Sex cord tumor with annular tubules (SCTAT) is a highly rare type of ovarian sex cord-stromal tumor (SCST), the diagnosis of which remains to be challenging. The aim of this study was to scrutinize the utility of three immunohistochemical markers including Forkhead box protein 2 (FOXL2), SOX9, and beta-catenin and DICER1 mutation status in distinguishing SCTATs from other ovarian SCSTs. Nine cases of SCTAT, 10 Sertoli-Leydig cell tumor (SCLT), 10 adult-type granulosa cell tumor (AGCT), and 8 juvenile-type granulosa cell tumor (JGCT) were included in the study. SCTATs were characterized by diffuse and strong expression of SOX9, focal and weak expression of FOXL2, and the absence of DICER1 mutation. However, AGCTs and JGCTs displayed strong and diffuse expression of FOXL2, focal/no immunoreaction for SOX9. SLCTs generally showed moderate intensity of FOXL2 and SOX9 expression. Nuclear beta-catenin expression was observed in none of SLCT, 1/9 of SCTAT, 6/8 JGCT, and 4/10 AGCT cases, respectively. DICER1 hotspot mutation was detected in only 3 cases of SLCT and 2 cases of JGCT. We conclude that in addition to strong and diffuse SOX9 expression, weak/absent expression of FOXL2 is suggestive for the diagnosis of SCTAT. Hence, we suggest that inclusion of these two markers, SOX-9 and FOXL2, to the immunohistochemical panel helps in differentiation of SCTAT from other SCSTs in addition to morphologic findings. We also conclude that SCTATs of the ovary do not harbor DICER1 hotspot mutation

Management of Acquired Atresia of the External Auditory Canal

OBJECTIVE: The aim was to evaluate surgical techniques and their relationship to postoperative success rate and hearing outcomes in acquired atresia of the external auditory canal. MATERIALS and METHODS: In this article, 24 patients with acquired atresia of the external auditory canal were retrospectively evaluated regarding their canal status, hearing, and postoperative success. RESULTS: Acquired stenosis occurs more commonly in males with a male: female ratio of 2-3:1; it seems to be a disorder affecting young adults. Previous ear surgery (13 patients, 54.2%) and external ear trauma (11 patients, 45.8%) were the main etiological factors of acquired ear canal stenosis. Mastoidectomy (12/13) and traffic accidents (8/11) comprise the majority of these etiological factors. Endaural incision is performed in 79.2% and postauricular incision for 20.8% of cases during the operation. As types of surgical approach, transcanal (70.8%), transmastoid (20.8%), and combined (8.4%) approaches are chosen. The atretic plate is generally located at the bony-cartilaginous junction (37.5%) and in the cartilaginous canal (33.3%); the bony canal is involved in a few cases only. Preserved healthy canal skin, split-or full-thickness skin grafts, or pre-or postauricular skin flaps are used to line the ear canal, but preserved healthy canal skin is preferred. CONCLUSION: The results of surgery are generally satisfactory, and complications are few if surgical principles are followed.WoSScopu

A Selected Immunohistochemical Panel Aids in Differential Diagnosis and Prognostic Stratification of Subtypes of High-grade Endometrial Carcinoma: A Clinicopathologic and Immunohistochemical Study at a Single Institution

This study aimed to investigate whether a selected immunohistochemical panel (estrogen receptor, p53, ARID1A, PPP2R1A, HNF-1) could contribute to the diagnostic process of high-grade endometrial carcinomas (HG-ECs). We also aimed to analyze the correlation of these immunohistochemical results with several morphologic variables and survival data. After revising the diagnosis of 78 HG-ECs, immunohistochemical analysis was performed for each case. After immunohistochemical analysis, a specific diagnosis of prototypic HG-EC was established in most of the cases that were uncertain due to morphologic ambiguity. In the univariate analysis, older patient age, type II morphology, undifferentiated carcinoma and carcinosarcoma type of histology, altered p53 immunostaining, strong membranous staining of PPP2R1A, presence of lymphovascular invasion in serous carcinoma, and microcystic, elongated, and fragmented-type infiltration pattern in endometrioid carcinoma were significantly related to poor prognosis. In the multivariate analysis, only older patient age and carcinosarcoma or undifferentiated/dedifferentiated carcinoma type histology were found to be significantly poor prognostic factors (P=0.011), whereas advanced FIGO stage and type II histology were found to be correlated with poor prognosis, but did not reach statistical significance. We suggest that immunohistochemistry should be used in the differential diagnosis of HG-ECs, especially those with ambiguous morphology. Markers used in this study made a valuable contribution to the diagnostic process as well as prediction of prognosis

Does endometriosis have an effect on the survival of women with synchronous endometrial and ovarian cancer?

Purpose: Synchronous endometrial and ovarian cancer is defined as the concurrent presence of ovarian cancer with endometrial cancer. We aimed to evaluate whether there is an effect of endometriosis on progression-free survival and overall survival of women with synchronous endometrial and ovarian cancer. We also compared these findings with the patients having endometrial-only tumors and ovarian-only tumors. Methods: The patients who underwent surgery for endometrioid or clear-cell endometrial-only tumors and/or ovarian-only tumors and synchronous endometrial and ovarian cancer between 2005 and 2016 were included in this cohort study. The effect of the presence of endometriosis on progression-free survival and overall survival in these women who met the criteria was determined using statistical methods. Women were also compared regarding their demographic, clinical, and pathological characteristics. Results: A total of 176 patients were included in this study. All histology types of tumors located in endometrium or ovary were endometrioid or clear-cell cancer. Endometriosis was present in 62 patients (35.2%), whereas adenomyosis was present in 44 patients (25%). Endometriosis was diagnosed more frequently in women with ovarian-only tumors and synchronous endometrial and ovarian cancer than those with endometrial-only tumors (59.2% vs 5.7%, p < 0.001 and 45.7% vs 5.7%, p < 0.001, respectively). The patients with endometriosis showed no significantly longer progression-free survival and overall survival (hazard ratio = 1.70; 95% confidence interval = 0.48-6.03; p = 0.408 and hazard ratio = 1.67; 95% confidence interval = 0.30-9.44; p = 0.562, respectively). The presence of endometriosis was a stronger predictor for progression-free survival and overall survival comparing with the presence of adenomyosis. Conclusion: The women with synchronous endometrial and ovarian cancer should be informed that endometriosis has no detrimental effect on progression-free survival and overall survival

The effect of adenomyosis on endometrial cancer: a university hospital-based cohort study

Endometrial cancer (EC) can coexist with gynaecological diseases including adenomyosis which can be defined as the location of endometrial cells within the myometrium. Our aim was to clarify the impact of adenomyosis on the clinical and survival outcomes of EC. We included the patients who underwent an operation for EC and had concurrent adenomyosis in this retrospective cohort study. All clinicodemographical and tumour characteristics with survival outcomes of the patients were analysed comparatively. A total of 763 patients who met the eligibility criteria were included. Of those, 591 patients in the non-adenomyosis group and 172 patients in the adenomyosis group were examined. Disease-specific survival (DSS) was significantly prolonged while progression-free survival (PFS) was not affected by the presence of adenomyosis (p = .004 vs. p = .161). However, adenomyosis did not remain as an independent prognostic factor for EC in multivariate analysis (p = .341). These patients with coexistent adenomyosis and EC have better clinicopathological characteristics and less advanced tumour. Although adenomyosis is associated with prolonged DSS, it has no prognostic importance for survival outcomes of the patients with EC.IMPACT STATEMENT What is already known on this subject? Endometrial cancer (EC) can coexist with other gynaecological diseases including uterine adenomyosis. Adenomyosis is typically diagnosed by the pathological evaluation of the uterus following hysterectomy, although diagnosis is possible with imaging methods However, the coexistence of adenomyosis and EC is controversial in the literature. What do the results of this study add? To the best of our knowledge, our study is the largest study performed at a single university hospital. All potential confounding factors including clinicodemographical characteristics of the patients, examination of histopathology slides by the experienced gynaecological pathologists, evaluation of all included factors that may affect the survival outcomes of EC by multivariate analysis were examined. Although adenomyosis is associated with prolonged disease-specific survival (DSS), it has no prognostic importance for survival outcomes of the patients with EC. What are the implications of these findings for clinical practice and/or further research? Women having coexistent adenomyosis and EC should be informed about the impact of adenomyosis on the survival outcomes of EC

Clinicopathological analysis of borderline ovarian tumours and risk factors related to recurrence: experience of single institution

This study was conducted to determine the demographic and clinicopathologic characteristics and evaluate the prognostic value of various factors, such as the extensiveness of surgery, related to the tumour itself and the clinical features in the recurrence of borderline ovarian tumours (BOT). We retrospectively evaluated the data of 103 patients with a borderline ovarian tumours treated at our institution between the years 2000 and 2012. The median age was 37 (16-79) years and the majority of the patients were premenopausal (76.7%). During the follow-up, 16 recurrences were observed (15.5%). The multivariate analysis showed that the micropapillary architecture and fertility sparing surgery were the only significant independent predictors for the development of a recurrence amongst all of the demographic and clinicopathological features. In our study group, we identified that the micropapillary architecture itself and the fertility sparing surgery had a significant impact on the development of a BOT recurrence. The patients who possess these features should be followed up more closely for a long time period
