The rate of segmental resection for early stage non-small cell lung carcinoma (NSCLC) is increasing. However, the indications remain controversial. The aim of this study is to analyze the preliminary results of thoracoscopic segmental resection in early stage NSCLC in terms of morbidity, oncological validity and survival. We report the preliminary results of a consecutive series of 226 thoracoscopic segmentectomies for suspicion of early stage NSCLC. PATIENTS AND METHODS: Between 2007 and 2016, we performed 322 thoracoscopic anatomical sublobar resections (ASLR)...

A feasibility study using a quantum cascade laser-based infrared microscope for the rapid and label-free classification of colorectal cancer tissues is presented. Infrared imaging is a reliable, robust, automated, and operator-independent tissue classification method that has been used for differential classification of tissue thin sections identifying tumorous regions. However, long acquisition time by the so far used FT-IR-based microscopes hampered the clinical translation of this technique. Here, the used quantum cascade laser-based microscope provides now infrared images for precise tissue classification within few minutes...

The ability to histologically assess surgical specimens in real-time is a long-standing challenge in cancer surgery, including applications such as breast conserving therapy (BCT). Up to 40% of women treated with BCT for breast cancer require a repeat surgery due to postoperative histological findings of close or positive surgical margins using conventional formalin fixed paraffin embedded histology. Imaging technologies such as nonlinear microscopy (NLM), combined with exogenous fluorophores can rapidly provide virtual H&E imaging of surgical specimens without requiring microtome sectioning, facilitating intraoperative assessment of margin status...

BACKGROUND: Postoperative pancreatic fistula (POPF) is a potentially debilitating complication following pancreatoduodenectomy (PD). There are limited data correlating pancreatic parenchymal histopathologic features specifically fat and fibrosis content with development of POPF after PD. METHODS: Patients who underwent PD (January 2010-May 2015) with archived pathologic slides were included. Each pancreatic neck transection margin was histologically graded for fat and fibrosis, scored from 0 to 4, and grader was blinded to clinical outcomes...

Intermediate filaments (IFs) are principal components of the cytoskeleton, a dynamic integrated system of structural proteins that provides the functional architecture of metazoan cells. They are major contributors to the elasticity of cells and tissues due to their high mechanical stability and intrinsic flexibility. The basic building block for the assembly of IFs is a rod-like, 60-nm-long tetrameric complex made from two antiparallel, half-staggered coiled coils. In low ionic strength, tetramers form stable complexes that rapidly assemble into filaments upon raising the ionic strength...

PURPOSE: Recently, it has been recognized that meniscocapsular ('ramp') lesions of the posterior one-third of the medial meniscus frequently occur during injuries causing ACL rupture, and that these lesions are easily missed at arthroscopy. Furthermore, it is clear that these lesions are biomechanically significant, adding to the deficits caused by ACL rupture, and that their repair can reverse this. The efficacy of an all inside repair technique has been questioned by some authors and by those who advocate a suture shuttle technique via an accessory posteromedial portal...

Invasive adenocarcinoma intraoperatively misdiagnosed as adenocarcinoma in situ or minimally invasive adenocarcinoma is more likely to undergo potentially insufficient resection. The purpose of our study was to evaluate the diagnostic accuracy of frozen section. We retrospectively reviewed 1,111 lung adenocarcinomas from January to March 2016 to evaluate the diagnostic performance of frozen section. A derivation cohort consisting of 436 cases of adenocarcinoma in situ or minimally invasive adenocarcinoma diagnosed by frozen section in the same period were analyzed to find predictive factors for invasive adenocarcinoma as the final diagnosis...

Meredith E Pittman, Rhonda K Yantiss
Intraoperative consultation requires skills in gross examination and histologic diagnosis, as well as an ability to perform rapid interpretations under time constraints. The aim of this review is to provide surgical pathologists with a framework for dealing with hepatic specimens in the frozen section area by covering common clinical scenarios and histologic findings. Differential diagnoses are considered in relation to primary hepatic neoplasia and metastatic diseases. Benign mimics of malignancy and other pitfalls in frozen section diagnosis of lesional tissue are covered...

BACKGROUND: Placental dysfunction is related to many pregnancy complications, but collecting placental specimens for investigation in large scale epidemiologic studies is often infeasible. Standard procedures involving immediate collection after birth and snap freezing are often cost prohibitive. We aimed to collect pilot data regarding the feasibility and precision of a simpler approach, the collection of tissue samples following 24 hours of refrigeration of whole placentae at 4°C, as compared to the "gold standard" of snap freezing excised tissue within 40 minutes of delivery for the assessment of inflammatory cytokines...

Despite the recent advent of neuro-radiographic techniques, creating a 'perfect' human brain atlas providing precise and consistent images with minimal distortion is practically difficult. In this study, we created a new human brain atlas from cadaveric brains with serial sections of 50 μm thickness covering the entire basal ganglia. Human cerebral hemispheres were obtained from 10 donated cadavers and fixed in 10% formalin solution, cut in a block measuring 50 mm × 30 mm × 50 mm around the midpoint of the anterior and posterior commissures and frozen at -40 °C...

Orexins are neuropeptides with pleiotropic functions, involved in the coordination of multiple versatile physiological processes, in particular related to food intake and several aspects of the reproductive process. Their actions are carried out through the bond with the related Orexin 1 (OXR1) and Orexin 2 (OXR2) G-protein-coupled receptors. Studies on the expression of the orexinergic system in the female genital organs are scarce and limited to preovulatory gametogenic follicles and corpora lutea isolated from the rest of the ovary...

Mass cytometry is a highly multiplexed single-cell analysis platform that uses metal tagged reagents to identify multiple cellular biomarkers. Current metal-tagged reagent preparation employs thiol-maleimide chemistry to covalently couple maleimide-functionalized metal-chelating polymers (MCPs) with antibodies (Abs), a process that requires partial reduction of the Ab to form reactive thiol groups. However, some classes of Abs (for example, IgM) as well as biomolecules lacking cysteine residues has been challenging to label using this method...

Cancer cells invade nerves through a process termed perineural invasion (PNI), in which cancer cells proliferate and migrate in the nerve microenvironment. This type of invasion is exhibited by a variety of cancer types, and very frequently is found in pancreatic cancer. The microscopic size of nerve fibers within mouse pancreas renders the study of PNI difficult in orthotopic murine models. Here, we describe a heterotopic in vivo model of PNI, where we inject syngeneic pancreatic cancer cell line Panc02-H7 into the murine sciatic nerve...
