RESUMO
Introduction: We investigated the role of E-cadherin and Ber-EP4 in tubal pregnancy by comparing their expressions in epithelial and trophoblastic cells both in ectopic tubal and intrauterine pregnancies. Methods: The Formalin-fixed paraffin embedded blocks of 17 intrauterine and 17 tubal pregnancies were immunohistochemically stained with E-cadherin and Ber-EP4. Results: E-cadherin was expressed in the epithelium, villous and extravillous trophoblast in tubal and intrauterine pregnancies but not in the syncytiotrophoblast. The staining intensity was lower in the extra-villous trophoblast in tubal ectopic pregnancies compared with intrauterine pregnancies. Ber-EP4 was expressed in the epithelium of tubal and intrauterine pregnancies and only in villous cytotrophoblast. The intensity of staining in tubal pregnancy was higher than in intrauterine pregnancy. Discussion: The loss of E-cadherin expression in extra-villous trophoblast and increased expression of Ber-EP4 in the villous cytotrophoblast may play a role in the formation of tubal pregnancy by allowing the blastocyst to attach to the tubal epithelium.
RESUMO
Endometriosis is one of the most common benign gynaecologic diseases and its clinical presentation is generally ovarian endometrioma. We aimed to assess the association of tumour markers with histopathological structure of ovarian endometriomas to assess their roles in clinical management. Data from 86 women who underwent laparoscopic surgery for ovarian endometrioma were evaluated. The possible risk factors for inadvertently removed normal ovarian parenchyma (IRNOP) during laparoscopic cystectomy and the relationship between tumour markers and histopathologic parameters of ovarian endometrioma were assessed. Age and the depth of penetration of endometrial tissue into the cyst wall showed a significant positive correlation with thickness of IRNOP. There was a significant negative correlation between IRNOP and the thickness of fibrosis on cyst wall. Thickness of fibrosis and the depth of penetration represented significant positive correlations with tumour markers (CA 125, CA 15-3, and CA 19-9), respectively. This is the first study that reveals the association between tumour markers and the histopathologic features of ovarian endometrioma. The outcome of the present study indicated that lower levels of tumour markers may permit a conservative management, rising levels may help in timing of a possible surgical intervention and high levels may help in counselling postoperative outcomes.Impact statementWhat is already known on this subject? Endometriosis is defined as a benign gynaecologic disease, and the vast majority of women who suffer from endometriosis are of reproductive age. Ovarian endometriotic cysts are found in one-fifth to one-half of patients with endometriosis. Laparoscopic cystectomy is accepted as the gold standard for the surgical management of ovarian endometriotic cysts because of the procedure's several clinical advantages, such as lower recurrence and higher pregnancy rates. However, studies have indicated that laparoscopic excision of an ovarian endometrioma capsule could be associated with a reduction in both the ovarian volume and the follicle count.What do the results of this study add? Our retrospective data indicate that tumour markers may have role in planning the management of ovarian endometriomas.What are the implications of these findings for clinical practice and/or further research? Low tumour markers levels may permit a conservative management, elevating levels may help in timing of a possible surgical intervention and finally high levels may help in counselling the patient about her possible postoperative outcomes.

OBJECTIVE: The aim of this study was to evaluate the diagnostic efficacy and utility of liquid-based cytology in ThinPrep (Cytyc Corporation, Boxborough, MA) for endometrial lesions in patients presenting with abnormal uterine bleeding. MATERIALS AND METHODS: Two hundred and thirteen women scheduled for dilatation and curettage because of abnormal uterine bleeding were enrolled in the study. After providing informed consent, all the women proceeded sequentially to endometrial cytology and then dilatation and curettage. RESULTS: In the premenopausal group, cytological failure was 4.8%, histopathological failure was 2.4%; cytologic insufficiency in the postmenopausal group was 2.1%, and histopathologic insufficiency was 19.6%. When cytologic and histopathological sufficiency rates were compared in all cases, cytologic insufficiency was 4.2% and histopathologic insufficiency was 6.1%. This difference was statistically significant (p < 0.039). The diagnostic accuracy, sensitivity, specificity, PPV, and NPV of the liquid-based endometrial cytology for premenopausal patients were 96.79, 58.33, 97.92, 70, and 96.58%, respectively. In the postmenopausal cases, the accuracy of diagnosis of endometrial cytology was 97.30%, sensitivity 100%, specificity 96.67%, PPV 87.50%, and NPV 100%. When cytologic and histopathologically inadequate cases were excluded, no cytologic and histopathological abnormal findings were found in endometrial thickness cutoff ≤ 5 mm for all patients. CONCLUSION: The use of liquid-based cytology with TVS may contribute to increasing the diagnostic accuracy of the test and reduce unnecessary D&C for women. When TVS is used as a triage indicator, regardless of menopausal status in ≤ 5 mm endometrial thickness cases, endometrial cytology is an absolutely reliable method for detecting cancer.

OBJECTIVES: Possible primary sites of pelvic serous cancers are, fallopian tubes, ovaries or peritoneum. Recent studies have revealed that a portion of these tumors originates from serous tubal intraepithelial carcinoma (STIC) at the distal end of fallopian tubes. In this study, the association of STIC with pelvic serous carcinomas and the pathologic parameters that indicate the tubes as the primary site were assessed. METHODS: In total, 495 pairs of fallopian tubes obtained via total abdominal hysterectomy and bilateral salpingo-oophorectomy between 2011 and 2013 were examined according to SEE-FIM protocol. Hematoxylin and eosin-stained slides were examined by pathologists. Suspicious areas were immunostained with p53 and Ki-67 to diagnose STIC precisely. RESULTS: Of the 495 cases, 110 cases were malignant. Among 34 cases of non-uterine serous carcinomas, 13 were diagnosed with STIC. STIC was located at the fimbrial end of the fallopian tubes in 12 cases. No STIC was identified in the gynecologic malignancies other than non-uterine serous pelvic carcinomas and benign gynecologic pathologies. Comparison of the ovarian and tubal cancer cases with and without STIC did not reveal a factor that helps to define the primary site. STIC was an important factor associated in a higher portion of the cases with bilateral ovarian cancer. CONCLUSION: The role of STIC in carcinogenesis continues to be discussed as it is unknown whether STIC is the precursor lesion or just associates with the malignancies. Discovering the accurate precursor lesions and tumor carcinogenesis is essential to prevent these malignancies and to develop early diagnostic methods.

OBJECTIVE: This study aimed to evaluate and reexamine materials of the patients with cervical biopsy revealing cervical intraepithelial neoplasia and their cone biopsies revealing no lesion. MATERIALS AND METHODS: Twenty-five patients with cervical biopsy revealing cervical intraepithelial neoplasia and cone biopsies revealing no lesion among 202 patients who had undergone cervical conization after colposcopically derived cervical biopsy between 2005 and 2011 were included in this study. Ki67 and P16 were applied to the all biopsy slides. The conization blocks of patients whose reevaluation results of the original biopsy slides were positive were completely sectioned to reexamine the presence of any lesion, and suspicious areas were stained with Ki67 and P16. RESULTS: Of the 25 patients' punch biopsies, no lesion was detected in 13 patients. The false positivity of first punch biopsy (52%) was the main reason for negative cone biopsy result after positive punch biopsy. Punch biopsies of the other 12 patients confirmed the lesions previously diagnosed. The detailed examination of conization specimens of the latter group showed 3 new low-grade cervical intraepithelial neoplasia, which had not been identified before. CONCLUSIONS: Discordance between cervical biopsy findings and cervical conization findings could result from misdiagnosis of cervical biopsy, failure in preparation of the whole conization material, and technical difficulties of conization. Ki67 and P16 staining can be used in such cases to clarify the diagnosis.

INTRODUCTION: Interpretation of changes and premalignant lesions in endometrial polyps can be challenging. We evaluated the clinical course of patients with focal gland crowdings in endometrial polyps via repeat biopsies and searched for possible morphological findings in the initial biopsy that may foresee a premalignant course. METHODS: Specimens diagnosed as endometrial polyp and focal gland crowding in patients who had a repeat biopsy in a 1-year period were reexamined. Morphological findings in the initial biopsies were recorded. The group whose repeat biopsies were "premalignant or malignant" (Group 1), and the group with "benign" repeat biopsies (Group 2) were compared. RESULTS: "Endometrial polyp and gland crowdings" was diagnosed in 115 specimens of which 38 patients had repeat biopsies. Among these 8 (21%) were diagnosed as "endometrial intraepithelial neoplasia (EIN)" (Group 1) and 30 (79%) as "benign" (Group 2). Morphological features in the initial biopsies were evaluated; PAX2 loss was 6 of 8 (75%) for Group 1 and 7 of 30 (23%) for Group 2 (P = .020), and altered epithelial cytological features were present in 5 of 8 (62%) versus 4 of 30 (13%) (P = .015), both significantly higher in Group 1. Dark intraluminal secretion, intraluminal histiocytes, intraglandular epithelial proliferation, and mean diameter of crowded gland areas were not statistically different between the 2 groups. CONCLUSION: "Focal gland crowdings" in endometrial polyps do carry a risk of EIN in subsequent biopsies. We suggest that the loss/decrease of PAX2 and altered epithelial cytological features in these areas in the initial biopsy are indicative of a premalignant course.
RESUMO
Introduction. Assigned female at birth transgender people go through a gender-affirming hormone therapy using testosterone. We aimed to define the histological changes in the removed ovaries of these patients and investigate the correlation of these changes to factors like chronological age and duration of hormone therapy. Methods. The ovaries of 84 patients who had at least 6 months of testosterone therapy before surgery were examined. Tunica albuginea thickness, cortical thickness, and number of different stages of follicles were recorded. Results. The mean age was 27.2 ± 4.9 years. Testosterone duration 25.8 ± 13.1 months. The mean tunica albuginea thickness was 356.4 ± 152.6â µm. The mean cortical thickness was 799.6 ± 245.6â µm. The number of primordial (C1) follicles was 18.03 ± 13.6 and antral (C3) follicles was 3.1 ± 1.9 per cm². When grouped as using therapy under or over 2 years the groups did not have differences in histological findings. Hormone duration did not correlate with histological findings except for a positive correlation with atretic follicle number. However, age was negatively correlated with number of follicles at all stages except atretic follicles and positively correlated with cortical thickness (P < .05). Conclusion. Testosterone therapy induces multifollicularity, stromal hyperplasia, and luteinization in some patients. Hormone duration did not correlate with ovarian histology whereas chronological age did suggesting an effect of age on ovarian reserve rather than duration of hormone therapy.

OBJECTIVE: Decorin is a leucine-rich proteoglycan, affects the proliferation, migration, and invasion of extravillous trophoblasts (EVTs). In this study, we aimed to determine the localization of decorin in the implantation site in human tubal ectopic pregnancy, to compare decorin expression levels in ectopic and intrauterine pregnancy, and to investigate the relationship between implantation depth of the tubal wall and expression levels of decorin. METHODS: 15 patients underwent salpingectomy for tubal ectopic pregnancy and 15 underwent curettage for voluntary interruption of pregnancy were included. All blocks were stained with decorin immunohistochemical staining. Trophoblastic cells of tubal Stage I-III and tubal epithelial and stromal cells were analyzed in terms of presence and intensity of decorin staining. RESULTS: Decorin was expressed in both tubal and intrauterine trophoblasts, stroma, and surface epithelium during the first trimester of pregnancy. Decorin staining intensity was significantly lower in the villous cytotrophoblasts and syncytiotrophoblasts in tubal ectopic pregnancies, compared to intrauterine pregnancies (p = 0.001 for both). Decorin staining intensity also significantly lower in the extravillous cytotrophoblasts and syncytiotrophoblasts in the tubal ectopic pregnancies (p = 0.002 and p = 0.001, respectively). There was no significant difference in the staining intensity of the trophoblasts and surface epithelial between Stage II and Stage III tubal invasion; however, the decorin expression was lower in the stroma in Stage III (p = 0.094). CONCLUSION: Decorin expression is significantly lower in trophoblastic cells of tubal ectopic pregnancies than the intrauterine pregnancies. Although it remains limited to explain the underlying cellular mechanisms, decorin seems to play a role in the development of tubal pregnancy.

OBJECTIVE: To evaluate immunohistochemical (IHC) staining of decorin and vascular endothelial growth factor (VEGF) of ovarian and endometrial tissues in patients with and without endometriosis. Study Design: Descriptive study. PLACE AND DURATION OF STUDY: Department of Obstetrics and Gynecology, ZeynepKamil Training and Research Hospital, Istanbul, Turkey, between Istanbul, TurkeyJanuary 2018 and June 2019. METHODOLOGY: Thirty patients, who underwent total abdominal hysterectomy (TAH) + bilateral salpingo-oophorectomy (BSO)/unilateral salpingo-oophorectomy (USO) and were in the proliferative phase of menstrual cycle,were included. The study population consisted of 20 patients (patient group) with an endometriomaand the control group consisted of 10 patients who were operated for benign gynecological pathologies.The ovarian and endometrial tissue specimens were collected from the archives. IHC staining was performed using decorin and VEGF. RESULTS: Decorin analysis showed a significantly higher intensity of staining in both endometrial and ovarian tissues in control group than patient group. Patients with endometriosis had a lower intensity of staining of decorin and a higher intensity of staining of VEGF compared to control group. There was a negative, statistically significant concordance between VEGF and decorin staining of endometrial tissues of both groups (concordance rate -0.560, p=0.001). Therewas a negative, statistically significant concordance between VEGF and decorin staining of ovarian tissues of both groups (concordance rate -0.564, p<0.001). CONCLUSION: Angiogenesis plays a critical role in endometriosisand interaction between decorin and VEGF,which suggests that decorin may be a promising molecule for the treatment of endometriosis. Key Words: Decorin, Endometriosis, Immunohistochemical staining, Vascular endothelial Growth factor.

We investigated programmed cell death 1 (PD-1) / programmed cell death ligand 1 (PD-L1) expression in high grade serous ovarian cancer (HGSOC) and its relationship to tumor infiltrating lymphocytes (TIL) and prognosis. Formalin fixed paraffin embedded (FFPE) samples of 94 HGSOC cases were included in the study. Immunohistochemical analysis (CD3, CD4, CD8, PD-1 and PD-L1) was performed. Samples were analyzed for expression of immune proteins in the peritumoral stromal and intratumoral areas, scored, and expression was correlated with overall survival, stage, and age. PD-L1 staining ratio with a score greater than 0 was found to have lower survival. There were two positive staining patterns, patchy/diffuse and patchy/focal patterns, in 24 (25.5%) cases. Considering the threshold value ≥5%, we demonstrated that the PD-L1 positive cancer cell membrane immunoreactivity rate and patchy/diffuse PD-L1 expression were 9.6% (nâ¯=â¯9). There was statistically significant relationship between high PD-1 scores and PD-L1 cases of ≥ 5%. A statistically significant difference was found between PD-L1 staining and survival in patients with a threshold ≥ 5%. However an appropriate rate for treatment was determined in 9.6% cases. There was a statistically significant correlation between PD-1 positive TIL score and intratumoral CD3, peritumoral stromal CD3, intratumoral CD4 and intratumoral CD8 positive cells. Survival was lower in cases with higher PD-L1 positive stromal TIL score.
RESUMO
Although primary bronchopulmonary fibrosarcoma is a rare tumor, it may be characterized by the symptoms of acute respiratory distress occurring during the first moments of life in a newborn. It is one of the leading congenital malignant neoplasms of the lung, but is considered a borderline tumor since its biological behavior is much more favorable than that of adult fibrosarcomas. In the absence of metastases, complete resection is curative. Histopathological diagnosis is not simple, as the microscopic characteristics may be confused with benign fibromatosis or malignant mesenchymal neoplasms. In this case report, we present a case of congenital pulmonary spindle cell tumor showing the features of fibrosarcoma, and we discuss the differential diagnosis of spindle cell lesions localized within the thorax.

OBJECTIVES: To investigate the effects of a second cytology preparation on cytological diagnosis in high-risk HPV positive and PaP smear-negative cases. METHODS: This retrospective study was conducted with 57 cases who underwent cytological evaluation and cotest in our center in 2016-2017. All of these cases were high-risk HPV positive, PaP smear-negative and had a second preparation. All preparations were re-evaluated by a cytopathologist and a pathologist. Twenty-five of the cases who had a positive diagnosis in the second preparation had a cervical biopsy. RESULTS: In 46 (80%) of the cases, the cytological diagnosis was the same and negative in the first and second preparations. Second preparations of 11 cases (19.2%) were positive. Twenty of 25 patients (77%) with cervical biopsy had premalignant lesion. CONCLUSION: In high-risk HPV positive and PaP smear-negative cases, patient management is different from cases where these two tests are positive together. According to our results, 19.2% of high-risk HPV positive and PaP smear-negative cases were given positive cytological diagnosis by second cytology preparation. Biopsy results support our cytological findings. The incidence of positive cytological diagnosis increases in PaP smear with the second preparation. With this protocol, patient management changes, follow-up time and number can be reduced.
RESUMO
PURPOSE: We aimed to assess ocular surface characteristics in children with Hashimoto's thyroiditis without thyroid-associated ophthalmopathy and compare the results with those of healthy children. METHODS: Twenty-two children with Hashimoto's thyroiditis (Group 1) and 20 healthy children without any ocular and/or systemic disorder (Group 2) were enrolled in the study. Ocular Surface Disease Index questionnaire, tear film osmolarity measurement (TearLab Osmolarity System, San Diego, CA, USA), Schirmer and tear film breakup time tests, meibography, and conjunctival brush cytology were performed and compared the results between the groups. RESULTS: The study group included 19 girls and 3 boys in Group 1 and 12 girls and 8 boys in Group 2 (p=0.081). Thyroid-associated ophthalmopathy was not identified in any of the patients. Mean tear film osmolarity was 310.23 ± 11.98 mOsm/l in Group 1 and 313.60 ± 15.03 mOsm/l in Group 2 (p=0.424). Mean Schirmer test score was lower in Group 1 (14.91 ± 6.27) compared with Group 2 (23.60 ± 5.63) (p=0.001). Mean tear film breakup time was lower in Group 1 (11.78 ± 4.07) compared with Group 2 (15.1 ± 1.6) (p=0.013). Moreover, mean meibomian gland area loss was 25.01% ± 10.04% in Group 1 and 16.54% ± 6.02% in Group 2 (p=0.002). Conjunctival cytologic analysis in Group 1 revealed grade 0 changes in 6 patients (27.3%), grade 1 changes in 14 patients (63.6%), and grade 2 changes in 2 patients (9.1%), whereas 18 patients (90%) had grade 0 changes and 2 patients (10%) had grade 1 changes (p=0.001) in Group 2. CONCLUSIONS: The study demonstrates several ocular surface changes in children with Hashimoto's thyroiditis. These findings may indicate a tendency for dry eye in pediatric Hashimoto's thyroiditis patients without clinical evidence of thyroid-associated ophthalmopathy.

BACKGROUND: The objective of this study was to compare the classical method and Sectioning and Extensively Examining the Fimbriated End Protocol (SEE-FIM) in detecting microscopic lesions in fallopian tubes with gynecological lesions. METHODS: From a total of 1,118 cases, 582 with various parts of both fallopian tubes sampled in three-ring-shape sections and 536 sampled with the SEE-FIM protocol were included in this study. Pathological findings of cases with endometrial carcinoma, non-uterine pelvic malignant tumor, ovarian borderline tumors, premalignancy, and benign lesions were compared. RESULTS: We detected two tubal infiltrative carcinomas among 40 uterine endometrioid adenocarcinomas, 15 serous tubal intraepithelial carcinomas in 39 non-uterine pelvic serous high-grade carcinoma cases, seven papillary tubal hyperplasias in 13 serous borderline tumor cases, and 11 endometriotic foci and four adenomatoid tumors among all cases sampled with the SEE-FIM protocol. Using the classical method, we detected only one serous tubal intraepithelial carcinoma in 113 non-uterine pelvic serous high-grade carcinoma cases and two papillary tubal hyperplasia cases in 31 serous borderline tumors. We did not identify additional findings in 185 uterine endometrioid carcinoma cases, and neither endometriotic focus nor adenomatoid tumor was shown in other lesions by the classical method. CONCLUSIONS: Benign, premalignant, and malignant lesions can possibly be missed using the classical method. The SEE-FIM protocol should be considered especially in cases of endometrial carcinoma, nonuterine pelvic serous cancers, or serous borderline ovarian tumors. For other lesions, at least a detailed examination of the fimbrial end should be undertaken.
RESUMO
Colloid carcinoma, which is a very rare tumor of the uterine cervix, is composed of an excessive amount of mucus and a relative paucity of tumoral glandular cells within them. Herein, we report a rare case of colloid carcinoma of the cervix with adenocarcinoma in situ (AIS), intestinal and usual types, and endocervical adenocarcinoma (usual type) components. We also discuss the morphological and immunohistochemical characteristics of this tumor. A 51-year-old woman was referred to our outpatient clinic with the symptom of genital bleeding lasting for 5 months. She had a cervix surrounded by an irregular tumor with a diameter of 5 cm. The colloid carcinoma cells were positive for MUC2, MUC5AC, and cytokeratin (CK) 7, focal positive for CDX2, and negative for MUC6 and CK20. Also, the intestinal type AIS showed a similar staining pattern. Colloid carcinoma cells producing mucin showed an intestinal phenotype and AIS. The intestinal type can be considered as a precursor lesion of colloid carcinoma.
RESUMO
Here, we present a rare case of a hydatid cyst in a 25-year-old woman, mimicking a uterine leiomyoma. The patient was admitted with lower abdominal pain and tenesmus, and ultrasonographic examination revealed a 10×10 cm uniloculated mass with regular borders in the myometrium. The patient was operated with an initial diagnosis of a uterine leiomyoma with cystic degeneration, which was found to be hydatid cyst during frozen section and confirmed with the identification of protoscoleces during microscopy. This rare case report indicates the necessity of considering hydatid disease in the differential diagnosis of pelvic cysts, especially in endemic regions.

BACKGROUND/AIM: Histopathological examination is crucial for the effective management of endometrial polyps. Immunohistochemical markers such as p16 and c-Kit may facilitate the differential diagnoses of benign and malignant polyps. The aim of the present study was to explore the expression levels of c-Kit (CD117) and p16 in endometrial polyps of postmenopausal women. MATERIALS AND METHODS: Twenty-five hysterectomy specimens with malignant endometrial polyps and hysterectomy or polypectomy specimens featuring 55 benign polyps were studied. The polyps were immunohistochemically stained for p16 and c-Kit, and differences in the expression levels of these proteins in the glandular and stromal components of benign polyps and the benign regions of the malignant polyps were assessed by using Fisher's exact test. RESULTS: The glandular components of malignant polyps exhibited significantly more intense p16 immunostaining than did benign polyps. Most immunoreactive cells were glandular cells exhibiting tubal metaplasia. The stromal components of either type of polyp did not differ in terms of p16 immunostaining. The extent of c-Kit immunostaining in benign and malignant polyps was similar. CONCLUSION: The extensive tubal metaplasia in and the p16 immunoreactivity of the glandular components of malignant polyps may be useful to distinguish such polyps from benign polyps.

OBJECTIVES: To evaluate the risk factors for the recurrence of ovarian endometrioma after laparoscopic cystectomy. STUDY DESIGN: Reproductive aged patients who underwent laparoscopic ovarian endometriotic cystectomy and with histopathologically confirmed diagnosis of ovarian endometrioma were evaluated retrospectively. Histopathologic specimens were reevaluated and histopathologic characteristics of ovarian endometriotic cysts (thickness of cyst wall, thickness of fibrosis [ToF], thickness of ovarian tissue, the number of follicles per cyst, the depth of penetration [DoP] of endometrial tissue into the cyst wall) were determined. Along the determined histopathologic findings, demographic characteristics (age at surgery, number of pregnancies), clinical symptoms (dysmenorrhea, infertility), intraoperative findings (revised American Society for Reproductive Medicine [rASRM] stage), imaging features (bilaterality, cyst diameter), and biochemical parameters (Ca125, Ca19.9, Ca15.3) were evaluated as possible risk factors for the recurrence of endometrioma. The variables with p<0.2 in univariate analysis were introduced into regression analysis to determine the risk factors for recurrence. RESULTS: There were statistically significant differences in age group (≤35 years and >35 years), the ToF and DoP between patients with recurrence and those with no recurrence. In Cox regression analysis, age ≤35 years and DoP were significant risk factors for presence of recurrence. DoP, ToF, preoperative cyst diameters in ultrasonographic examination were inversely correlated with recurrence interval. In multivariate regression analysis, the DoP was found the only significant risk factor for the recurrence interval. 1.2mm of DoP was found as the optimum cut off value for presence of recurrence according to Youden index criteria in ROC curve analyze. The sensitivity (62.9%), specificity (75%) were obtained at the cut off value of 1.2mm for DoP. CONCLUSION: Histopathological features of ovarian endometriotic cyst may have important roles on predicting the recurrence of the endometrioma. Predicting the recurrence risk of particular patient is very important in future management of the disease. Knowing the recurrence risk of an endometrioma will help in deciding the optimal treatment modalities for each individual patient. High risk patients should be offered appropriate treatments according to the clinical status without delay and low risk patients should be protected from overtreatment.

BACKGROUND: Presepsin is an inflammatory marker released from monocytes and macrophages as an acute reaction to microbial infection. We hypothesized that it may be useful in pregnancies with preterm premature rupture of the membranes (PPROM) for early diagnosis of subclinical chorioamnionitis. AIMS: To determine whether the plasma presepsin level has any diagnostic or prognostic value for subclinical chorioamnionitis in pregnancies complicated with PPROM. STUDY DESIGN: Prospective cohort study. METHODS: Fifty-three singleton pregnancies between 23 and 28 weeks of gestation diagnosed with PPROM were prospectively included in the study. Venous blood samples were collected at admission, at the 48th hour of admission, and at the time of delivery to determine presepsin and C-reactive Protein (CRP) levels and white blood cell (WBC) counts. Chorioamnionitis was diagnosed by microscopic examination of the placenta and cords. RESULTS: Of the 53 PPROM cases included in the study, 41 (77.4%) had histologically confirmed chorioamnionitis. Neonatal sepsis developed in 24 (45.3%) of the newborns. The median presepsin level at admission was 135.0 pg/mL for pregnancies with subclinical chorioamnionitis and 113.5pg/mL for pregnancies without chorioamnionitis (p=0.573). There was also no significant difference between subclinical chorioamnionitis (+) and (-) cases in terms presepsin levels at the 48th hour and at delivery. However, chorioamnionitis (+) cases showed a significant decrease in both presepsin level and WBC count at the 48th hour after the administration of antibiotics, which increased significantly at delivery (p<0.001 and p=0.011, respectively). CONCLUSION: The striking fluctuations in presepsin level after the diagnosis of PPROM can be used to predict subclinical chorioamnionitis and determine the optimal timing of delivery before the clinical signs of chorioamnionitis are established. However, presepsin level itself was neither diagnostic nor prognostic for neonatal sepsis.
RESUMO
PURPOSE: To compare tear film osmolarity (TFO) and other dry eye tests between diabetic children and normal healthy children. MATERIALS AND METHODS: Twenty-six diabetic children (Group 1) and 20 healthy children without any ocular and/or systemic disorder (Group 2) were enrolled in the study. Detailed ocular surface assessment including, ocular surface disease index (OSDI) questionnaire, TFO measurement (Tear Lab Osmolarity System, San Diago, CA, USA), corneal epithelial thickness (CET) measurement using the anterior segment optical coherence tomography (OCT) (RTVue CAM, Optovue Inc, CA, USA), tear film break-up time (TFBUT) test, Schirmer test, meibography, and conjunctival brush cytology were performed. The results were compared between the groups. RESULTS: The mean TFO was significantly higher in Group 1 (328.8 ± 12.8) than Group 2 (313.6 ± 15.1) (p = 0.001). The mean Schirmer test score was significantly lower in Group 1 (16.7 ± 5.1) than Group 2 (23.6 ± 5.6) (p = 0.00). Cytologic analysis revealed grade 0 changes in 11 patients (42.3%), grade 1 changes in 13 patients (50%), and grade 2 changes in 2 patients (7.7%) in Group 1 whereas grade 0 changes in 18 patients (90%) and grade 1 changes in 2 patients (10%) were observed in Group 2 (p = 0.004). The TFO levels were significantly associated with HbA1c levels (r = 0.459, p = 0.018). CONCLUSION: The study revealed significantly higher TFO, lower Schirmer test scores and changes in conjunctival cytology in diabetic children. Altered ocular surface changes in diabetic children may be due to the result of increased TFO.
