Reproducibility of endometrial intraepithelial neoplasia diagnosis is good, but influenced by the diagnostic style of pathologists
Endometrial intraepithelial neoplasia (EIN) applies specific diagnostic criteria to designate a monoclonal endometrial preinvasive glandular proliferation known from previous studies to confer a 45-fold increased risk for endometrial cancer. In this international study we estimate accuracy and precision of EIN diagnosis among 20 reviewing pathologists in different practice environments, and with differing levels of experience and training. Sixty-two endometrial biopsies diagnosed as benign, EIN, or adenocarcinoma by consensus of two expert subspecialty pathologists were used as a reference comparison to assess diagnostic accuracy of 20 reviewing pathologists. Interobserver reproducibility among the 20 reviewers provided a measure of diagnostic precision. Before evaluating cases, observers were self-trained by reviewing published textbook and/or online EIN diagnostic guidelines. Demographics of the reviewing pathologists, and their impressions regarding implementation of EIN terminology were recorded. Seventy-nine percent of the 20 reviewing pathologists' diagnoses were exactly concordant with the expert consensus (accuracy). The interobserver weighted kappa values of 3-class EIN scheme (benign, EIN, carcinoma) diagnoses between expert consensus and each of reviewing pathologists averaged 0.72 (reproducibility, or precision). Reviewing pathologists demonstrated one of three diagnostic styles, which varied in the repertoire of diagnoses commonly used, and their nonrandom response to potentially confounding diagnostic features such as endometrial polyp, altered differentiation, background hormonal effects, and technically poor preparations. EIN diagnostic strategies can be learned and implemented from standard teaching materials with a high degree of reproducibility, but is impacted by the personal diagnostic style of each pathologist in responding to potential diagnostic confounders
Neurocognitive functions after beating heart mitral valve replacement without cross-clamping the aorta
Background and aim of the study: Although neurologic outcome after cardiac surgery is well-established, neurocognitive functions after beating heart mitral valve replacement still needs to be elucidated. The aim of this study was to compare preoperative and postoperative neurocognitive functions in patients who underwent beating heart mitral valve replacement on cardiopulmonary bypass without cross-clamping the aorta. Methods: The prospective study included 25 consecutive patients who underwent mitral valve replacement. The operations were carried out on a beating heart method using normothermic cardiopulmonary bypass without cross-clamping the aorta. All patients were evaluated preoperatively (E1) and postoperatively (at sixth day [E2] and second month [E3]) for neurocognitive functions. Results: Neurologic deficit was not observed in the postoperative period. Comparison of the neurocognitive test results, between the preoperative and postoperative assessment for both hemispheric cognitive functions, demonstrated that no deterioration occurred. In the three subsets of left hemispheric cognitive function test evaluation, total verbal learning, delayed recall, and recognition, significant improvements were detected at the postoperative second month (E3) compared to the preoperative results (p = 0.005, 0.01, and 0.047, respectively). Immediate recall and retention were significantly improved within the first postoperative week (E2) when compared to the preoperative results (p = 0.05 and 0.05, respectively). Conclusions: The technique of mitral valve replacement with normothermic cardiopulmonary bypass without cross-clamping of the aorta may be safely used for majority of patients requiring mitral valve replacement without causing deterioration in neurocognitive functions
SEROUS VERSUS HIGH-GRADE ENDOMETRIOID ENDOMETRIAL CARCINOMA: IMMUNOHISTOCHEMISTRY OF RFP IS NOT USEFUL FOR DIFFERENTIATION
We evaluated the immunohistochemical expression of ret finger protein (RFP) along with conventional immunohistochemical markers in endometrioid and serous carcinomas of the endometrium.
A total of 124 endometrial carcinoma cases (24 grade 1 endometrioid, 60 grade 3 endometrioid, 40 serous) were retrieved from pathology archives. Tissue microarrays were constructed. The expression of RFP, WT1, ER., PR, p53 and p16 was examined immunohistochemically. Sensitivity, specificity, area under the receiver operating characteristic (ROC) curve, kappa statistic for interobserver reproducibility, Kruskal-Wallis test, Mann-Whitney U test and Fisher's exact tests were performed for statistical analyses.
The mean RFP score was 1.54 in grade 1 endometrioid, 4.31 in grade 3 endometrioid, and 6.31 in serous carcinomas (p 0.05), and significantly lower in grade 1 endometrioid carcinoma (p < 0.05). p16 and p53 staining patterns were able to differentiate between high-grade endometrioid and serous carcinoma (p < 0.001). ER, PR and WT-1 did not reach statistical significance for subtyping. The kappa values of the general agreement between the observers were 0.737 and 0.727 for endometrioid and serous carcinomas respectively (p < 0.001).
Diffuse p53 and p16 staining provides the most sensitive and specific immunomarkers for differentiating high-grade endometrioid and serous carcinomas
Uterine smooth muscle tumor of uncertain malignant potential: fertility and clinical outcomes
Objective: In this study, we aimed to evaluate the clinicopathological
features, obstetric, and oncological outcomes of patients diagnosed with
a uterine smooth muscle tumors of uncertain malignant potential (STUMP).
Methods: A dual-institutional, database review was carried out to screen
patients with STUMP who were treated with upfront surgery between
January 2006 and December 2017. Data including age at the time of
diagnosis, recurrence rate, disease-free survival, overall survival, and
fertility outcomes were retrospectively analyzed.
Results: Fifty-seven patients with STUMPs were included in the study.
The median age at the time of diagnosis was 42 (range, 16 to 75) years.
The median follow-up was 57 (range, 16 to 125) months. Eight patients
(14\%) had recurrence during follow-up. Recurrent STUMPs were seen in
seven patients and leiomyosarcoma after 14 months in one patient. Seven
patients with a recurrent STUMP survived, while the remaining patient
died. Recurrence rates were similar for women who underwent myomectomy
and those who underwent hysterectomy. The presence of uterine
localization of tumor (subserosal vs intramural-submucosal)
statistically significantly affected recurrence rates (odds ratio=5.72;
95\% confidence interval=1.349-24.290; p=0.018). Ten of 27 patients who
underwent myomectomy for uterine myoma had fertility desire. Seven
pregnancies were recorded.
Conclusions: Our study results suggest that fertility-sparing approaches
are feasible in patients with STUMP, although recurrence may be seen
Progressive hematoma in anterior neck after endovascular treatment of middle cerebral artery aneurysm
Abstract Background: Cervical hematomas can lead to airway compromise, a life threatening condition, regardless of the cause. The following case is the first presentation of cervical hematoma as a complication of endovascular treatment of middle cerebral artery aneurysm. Case report: A 49 year-old woman was scheduled for stent placement under general anesthesia for middle cerebral artery aneurysm. Few days before intervention, acetyl salicylic acid and clopidogrel treatment was started. Following standard monitoring and anesthesia induction, the patient's trachea was intubated with a 7.5 mm endotracheal tube and the procedure was completed without any complications. Three hours later, dyspnea developed and physical examination revealed progressive swelling and stiffness in the neck. Endotracheal intubation was performed with a 6 mm diameter uncuffed tube with the aid of sedation. The vocal cords were completely closed due to compression. There was no leak around the endotracheal tube. The rapidly performed computerized tomography scans showed an enormous hematoma around the neck and extravasation of contrast medium through superior thyroid artery. After coil embolization of superior thyroid artery, she was taken to the intensive care unit as intubated and sedated. Surgical exploration of the hematoma was not recommended by the surgeons, because she was on clopidogrel. After two days, the patient's trachea was extubated safely ensuring that the swelling was sufficiently ceased and leak detected around the endotracheal tube. Conclusions: Securing the airway rapidly by endotracheal intubation is the most crucial point in the management of cervical hematomas. Diagnostic and therapeutic procedures should be performed only afterwards
