Single-center experience of thoracoscopic sympathectomy for palmar hyperhidrosis with long-term postoperative questionnaire survey.

Objectives: Thoracoscopic sympathectomy is an effective treatment for palmar hyperhidrosis. However, compensatory hyperhidrosis occurs frequently as a postoperative complication of the procedure. The goal of this study was to elucidate the clinical significance of thoracoscopic sympathectomy using our surgical procedure.

Wnt2b and Wnt5a expression is highly associated with M2 TAMs in non‑small cell lung cancer.

Tumor‑associated macrophages (TAMs), particularly M2 macrophages, promote tumor progression, while genes encode a family of multi‑functional glycoproteins that serve an important role in tumorigenesis. Immunohistochemical studies were performed to evaluate Wnt2b and Wnt5a expression in tumor and stromal cells in M2 and M1 TAMs and Ki‑67 proliferation index in 160 consecutive patients with resected non‑small cell lung cancer (NSCLC). Overall, 52 tumors (32.

Evaluation of the postoperative course of East Asian eyelid reconstruction with free tarsoconjunctival graft transplantation: A Japanese single-centre retrospective study.

Although eyelid reconstruction by transplanting an autologous free tarsoconjunctival graft (FTG) is a well-established technique, few studies have examined the postoperative course of FTG transplantation for East Asian eyelids, including those of Japanese patients. Therefore, this study investigated complication and reoperation rates after FTG transplantation in the reconstruction of East Asian (Japanese) eyelids. This study included 42 eyelids wherein posterior lobe reconstruction after resection of a malignant tumour of the eyelid was performed by FTG transplantation between 2007 and 2019 at Niigata University Medical and Dental Hospital.

Choroid structure analysis following initiation of hemodialysis by using swept-source optical coherence tomography in patients with and without diabetes.

We aimed to evaluate choroid structural changes using swept-source optical coherence tomography (SS-OCT) following hemodialysis initiation in diabetic and nondiabetic patients with end-stage kidney disease (ESKD). In this multicenter, prospective, cross-sectional study, diabetic (DM group; 30 eyes; 16 patients) and nondiabetic patients (NDM group; 30 eyes; 15 patients) with ESKD were evaluated after hemodialysis initiation. SS-OCT findings were analyzed using a manual delineation technique and binarization method before the first and last hemodialysis sessions, conducted approximately 2 weeks apart.

The natural course of IgG4-related ophthalmic disease after debulking surgery: a single-centre retrospective study.

Objective: This study aimed to examine the natural course and relapse rate of IgG4-related ophthalmic disease (IgG4-ROD) after debulking surgery in Japanese patients.

Methods And Analysis: This retrospective review included patients with IgG4-ROD who did not undergo further treatment following debulking surgery. The patients were diagnosed between January 2009 and December 2018 at the Department of Ophthalmology and Pathology, Niigata University Medical and Dental Hospital.

The Role of Mutation Rates of GNAQ or GNA11 in Cases of Uveal Melanoma in Japan.

GNAQ and GNA11 mutations are thought to be important for the tumorigenesis of uveal melanoma. Although previous studies have reported on mutation rates in cases of uveal melanoma, presently, no such report for the Japanese population exists. In this study, we examined the frequency of GNAQ and GNA11 somatic mutations in cases of uveal melanoma in Japan and their relationship with clinicopathologic features or Ki-67-positive cell rates (Ki-67 labeling index: Ki-67 LI) using immunofluorescence methods.

Trametinib plus 4-Methylumbelliferone Exhibits Antitumor Effects by ERK Blockade and CD44 Downregulation and Affects PD-1 and PD-L1 in Malignant Pleural Mesothelioma.

Introduction: Malignant pleural mesothelioma (MPM) is a highly aggressive malignancy in which the mitogen-activated protein kinase pathway plays a critical role in the regulation of tumorigenesis. Hyaluronic acid (HA) is a major component of the extracellular matrix, and elevated HA levels with a concurrent increase in malignant properties are associated with MPM.

Methods: We evaluated the effects of trametinib, a mitogen-activated protein kinase (MEK) inhibitor, and 4-methylumbelliferone (4-MU), an HA synthesis inhibitor, alone and in combination on MPM cells in vitro and in vivo.

Is volumetric 3-dimensional computed tomography useful to predict histological tumour invasiveness? Analysis of 211 lesions of cT1N0M0 lung adenocarcinoma.

Objectives: The purpose of this study was to use Hounsfield unit (HU) thresholds of computed tomography (CT) images to predict pathological lymph node metastasis and tumour invasiveness of cT1N0M0 lung adenocarcinoma on 3D evaluations.

Methods: Preoperative CT images of 211 lesions of surgically resected cT1N0M0 lung adenocarcinoma were retrospectively examined. The tumour size was calculated in 1D, 2D and 3D views.

Second relapse of solitary fibrous tumor within 20 years of initial resection.

A 64-year-old woman presented with a sessile solitary fibrous tumor in the right thoracic cavity. She had undergone 2 solitary fibrous tumor resections 7 and 20 years previously. The latest histological findings were identical to the previous, and pathologically benign.

Thymic Neuroblastoma within a Thymic Cyst in an Adult.

Case Presentation: A 65-year-old female patient with no clinical manifestations was hospitalized for examination and treatment of an anterior mediastinal tumor found at the time of a regular health checkup. Enhanced computed tomography (CT) and magnetic resonance imaging revealed a cystic lesion containing a solid tumor. Positron emission tomography-CT demonstrated increased uptake in the solid lesion.

[A variety of orbital lymphangioma treatments: one case treated with orbital decompression therapy and the other case with intralesional injection of OK-432 therapy].

Background: Orbital lymphangioma can result in ocular emergencies due to acute enlargement, leading to painful proptosis, compressive optic neuropathy, exposure keratopathy, restrictive ocular motility and increased intraocular pressure. Treatment methods and clinical courses of two cases with orbital lymphangioma are reported, one with orbital decompression therapy and the other with intralesional injection of OK-432 therapy. CASE 1: An 8-year-old girl had multilocular cystic orbital intracornal lymphangioma.

Changes of scleral sulfated proteoglycans in three cases of nanophthalmos.

Purpose: To examine the composition of scleral sulfated proteoglycans in three nanophthalmic eyes by electron microscopic histochemistry.

Methods: Scleral tissues from three cases of nanophthalmos were collected from the Niigata University Hospital for transmission electron microscopic examination. Sulfated proteoglycans were studied using the cuprolinic blue (CB) dye binding method in conjunction with enzymatic digestion.

Phospholipase C delta-type consists of three isozymes: bovine PLCdelta2 is a homologue of human/mouse PLCdelta4.

To date, 12 phospholipase C (PLC) isozymes have been identified in mammals, and they are divided into five classes, beta-, gamma-, delta-, epsilon-, and zeta-type. PLCdelta-type is reported to be composed of four isozymes, PLCdelta1-delta4. Here we report that a screening for mouse PLCdelta2 from a BAC library with primers that amplify a specific region of bovine PLCdelta2 resulted in isolation of one clone containing the mouse PLCdelta4 gene.

Recurrent meningitis associated with complete Currarino triad in an adult--case report.

A 58-year-old woman presented with Currarino triad manifesting as recurrent meningitis. Currarino triad is a combination of a presacral mass, a congenital sacral bony abnormality, and an anorectal malformation, which is caused by dorsal-ventral patterning defects during embryonic development. She had a history of treatment for anal stenosis in her childhood.
