Radiographic and clinical outcomes using intraoperative magnetic resonance imaging for transsphenoidal resection of pituitary adenomas.

The utility and safety of intraoperative MRI (iMRI) for resection of pituitary adenomas is not clearly established in the context of advances in endoscopic approaches. The goal in this study was to evaluate the safety and efficacy of iMRI for pituitary adenoma resection, with endoscopic transsphenoidal (ETS) versus microscopic transsphenoidal (MTS) approaches.

Appendageal Tumors and Tumor-Like Lesions of the Testis and Paratestis: A 32-Years of Experience at a Single Institution.

The testicular hilum and paratestis contain several embryologically diverse anatomic structures, including the spermatic cord, tunica vaginalis, epididymis, rete testis, and several other embryonic remnants. Several benign and malignant lesions arise from these morphologically distinct structures, and, due to their proximity, it is challenging to classify and subsequently stage these tumors. Herein, we conducted a retrospective review of the paratesticular appendageal and rete testis tumors and tumor-like lesions diagnosed at our department from 1985 to 2016. Soft tissue lesions/tumors were excluded. A total of 146 paratesticular appendageal and rete testis tumors and tumor-like lesions were identified. Most were benign (n=107; 73%). Adenomatoid tumor (26%) was the most common benign tumor, followed by different types of cysts (19%), mesothelial hyperplasia (18%), serous cystadenoma (5.5%) and rete testis adenoma (4%). Malignant lesions comprised 23%, with mesothelioma the most common (15%), adenocarcinoma of the rete testis (4%), serous cystadenocarcinoma (2%), and papillary and clear cell adenocarcinoma of the epididymis (2%). Finally, serous borderline tumors and melanotic neuroectodermal tumor (retinal anlage tumors) comprised the remaining 4% of cases. In conclusion, a wide range of benign and malignant lesions can arise from the paratesticular region. Awareness of these lesions and their histologic spectrum is crucial to avoid diagnostic pitfalls and to allow pathologists to establish a correct diagnosis and subsequent treatment plan.

Risk-Adapted Cutoffs in Colorectal Cancer Screening by Fecal Immunochemical Tests.

Fecal immunochemical tests (FITs) for hemoglobin are increasingly used in colorectal cancer (CRC) screening. The use of uniform positivity thresholds (cutoffs) within screening populations is expected to imply lower positive predictive values (PPVs) and higher numbers of colonoscopies needed (numbers needed to scope [NNSs]) to detect advanced neoplasms among screening participants at lower risk compared with those at higher risk. We aimed to assess such variation and its potential implications in a large screening cohort.

The Safety of Radiofrequency Ablation Using a Novel Temperature-Controlled Probe for the Treatment of Residual Intraductal Lesions after Endoscopic Papillectomy.

Treatment of residual intraductal lesions after endoscopic papillectomy for ampullary adenomas is relatively difficult. Few studies have been conducted using intraductal radiofrequency ablation (RFA) in the treatment of such lesions, and no study has aimed to reduce the side effects of excessive heat caused by RFA. Recently, a temperature-controlled RFA probe was developed to avoid excessive heat. This study aimed to investigate the safety of this new RFA probe in the treatment of intraductal lesions of ampullary adenoma.

Association of PTP4A3 expression and tumour size in functioning pituitary adenoma: a descriptive study.

PTP4A3 is a subclass of a protein tyrosine phosphatase super family and is expressed in a range of epithelial neoplasms. We evaluated PTP4A3 expression and its association with clinicopathological parameters in different types of functioning pituitary adenomas.

Comparison of Fentanyl versus Meperidine in Combination with Midazolam for Sedative Colonoscopy in Korea.

Combination of midazolam and opioids is used widely for endoscopic sedation. Compared with meperidine, fentanyl is reportedly associated with rapid recovery, turnover rate of endoscopy room, and quality of endoscopy. We compared fentanyl with meperidine when combined with midazolam for sedative colonoscopy.

Sellar Pathologies Mimicking Pituitary Tumors.

The most common sellar pathology that merits neurosurgical attention is the pituitary adenoma. However, some developmental, inflammatory, and neoplastic lesions may primarily or secondarily involve the sella, mimicking pituitary tumors. Advances in imaging and endocrinological assessment have helped in the recognition of these less common sellar, supra sellar pathologies, which may occasionally create confusion in management. The most common developmental anomaly is the Rathke's cleft cyst and an increasingly recognized inflammatory pathology is the spectrum of hypophysitis. Neoplasms, viz. Craniopharyngioma, Germinoma, Langerhans's cell histiocytosis or metastasis, have more distinctive features in various age groups and are more likely to be correctly diagnosed on current imaging and managed accordingly. This review looks at mainly intraparenchymal pathologies, namely Rathke's Cleft Cyst and various hypophysitides, and will discuss their management strategies.
