Successful Re-ileostomy Using Skin Flap Formation Techniques.

A 61-year-old woman underwent an emergent operation with sigmoid colon cancer resection, colostomy, and ileostomy on colon perforation. The low ileostoma, caused by intra-abdominal bad conditions, had irritated the surrounding skin after surgery, intermittently forcing the patient to fast for a certain period. Six months after the operation, under the judgment that re-ileostomy, essential for hospital discharge, seemed very difficult through another laparotomy, we attempted to make the ileostoma higher not with pulling the ileum from the abdomen but with lowering the surrounding skin using skin flap formation techniques.

Effect of Regional Anesthesia on Intraoperative Hyperkalemia in Patients With Chronic Kidney Disease: Two Case Reports.

Intraoperative hyperkalemia is particularly common in patients with chronic kidney disease (CKD). We report two cases of intraoperative hyperkalemia occurring under general anesthesia, while potassium levels remained stable with regional anesthesia alone. Case 1 involved a 69-year-old male with CKD who underwent total thyroidectomy under general anesthesia and developed intraoperative hyperkalemia, requiring glucose-insulin (GI) therapy.

Inhibition of ROS1 activity with lorlatinib reversibly suppresses fertility in male mice.

Background: Inhibition of sperm maturation in the epididymis is a promising post-testicular strategy for short-acting male contraceptives. It has been shown that ROS1, a receptor tyrosine kinase expressed in the epididymis, is essential for epididymal differentiation, sperm maturation, and male fertility in mice. However, it is unknown if inhibition of ROS1 suppresses male fertility reversibly.

Feasible Nipple Preservation Techniques for Breast Cancer with Slight Nipple Retraction.

Introduction: Nipple retraction has long been regarded as an absolute contraindication factor for nipple preservation in breast cancer surgery.

Case Presentation: A 62-year-old woman was referred to our hospital for the treatment of breast cancer with slight nipple retraction. Imaging findings showed neither direct cancer infiltration to the nipple-areolar complex nor lymphadenopathy.

Pitfalls on image evaluation of tumor viability and anti-tumor efficacy in metastatic mucinous breast cancer: A case report.

A 66-year-old woman with metastatic mucinous breast cancer was referred to our hospital. The patient had lymph node and multiple lung metastases judged as progressive disease. Positron emission tomography showed radio tracer uptake neither in the axillary lymph nodes nor in the lung metastases.

A case of breast cancer developed in the chronic expanding hematoma cyst wall.

No studies have reported breast cancer cases developed in the chronic expanding hematoma (CEH). Case presentation: A 47-year-old woman was referred to our hospital for the treatment of a large breast mass. Ultrasound showed that the tumor had an intra-cystic tumor pattern.

Apocrine Adenoma of the Breast Showing Unique Image Findings.

Introduction: Apocrine adenoma of the breast is extremely rare and its typical images remain uncertain.

Case Presentation: A 66-year-old woman was incidentally found of her left breast tumor with computed tomography for ascending colon cancer staging work. Mammography showed a well-demarcated oval mass.

Multidisciplinary Treatment for Locally Advanced Mucinous Breast Cancer.

Background: Due to its indolent biology and high estrogen receptor positivity of mucinous breast cancer, vast majority of locally advanced mucinous breast cancer (LABC) are treated with first-line endocrine therapy.

Case Presentation: A 50-year-old woman was referred to our hospital for the treatment of her huge breast tumor. Computed tomography showed an oval solid tumor, 17 cm in size, and lymph node swelling in both the axilla and parasternum.

Metastatic lymph nodes of occult breast cancer show very low internal echoes.

A 62-year-old woman showed an elevation of carcinoembryonic antigen (CEA) level 15 years after the left breast cancer, i.e., tubule forming type luminal micro invasive cancer, operation.

Body talk and body dissatisfaction in Japanese university students: Longitudinal study using the Japanese Body Talk Scale.

This study evaluated the reliability and validity of the Japanese version of the Body Talk Scale (BTS), designed to measure negative fat talk, negative muscle talk, and positive body talk. The study also explored the longitudinal associations between each body talk category and body dissatisfaction. We conducted two separate studies among university students in Japan.

Intracystic gastrointestinal stromal tumor developed in the round ligament of the liver.

A 44-year-old woman was referred to our hospital for the examination and treatment of a presumed gallbladder tumor. Both ultrasound and computed tomography showed an intracystic tumor but failed to point out the discontinuity between the cystic lesion and the gallbladder. Magnetic resonance imaging, however, could clearly depict the presumed intracystic tumor and the discontinuity between the gallbladder and the target lesion.

Successful endoscopic treatment of a huge trichobezoar in a 10-year-old girl.

A 10-year-old girl was admitted to our hospital due to acute pancreatitis. Computed tomography showed an intra-gastric mass containing multiple small air bubbles. Ultrasound showed a well-circumscribed large oval mass with a broad acoustic shadow.

Clinically node-negative invasive lobular carcinoma of the breast showing multiple lymph node metastases.

A 73-year-old woman was pointed out of her right breast tumor on screening computed tomography (CT). Mammography showed distortion of the mammary gland and skin retraction. Ultrasound (US) showed an irregular tumor with hyperechoic haloes adjacent to the anterior tumor borders.

Focal coagulative necrosis of the liver in a patient with sustained virologic response to anti-hepatitis C virus therapy.

A 69-year-old woman with chronic hepatitis C virus (HCV) infection was referred to our hospital due to liver enzyme abnormalities. Four years after anti-HCV therapy, the patient with sustained virologic response and no clinical symptoms developed an oval hepatic mass with mixed high and low internal echoes near the portal vein on ultrasound. Magnetic resonance imaging (MRI) of the liver lesion showed a slightly hypo intense pattern on T1-weighted images, a hyper intense pattern both on T2- and diffusion-weighted images, a slight rim enhancement pattern with no intra-lesional enhancement up to the late phase, and a very low intense pattern on hepatobiliary phase images.

Comparison of the negative effect of remimazolam and propofol on cardiac contractility: Analysis of a randomised parallel-group trial and a preclinical ex vivo study.

Remimazolam is a newly developed ultra-short-acting benzodiazepine that exerts sedative effects. This study aimed to clarify the effects of remimazolam on cardiac contractility. In a randomised-parallel group trial, haemodynamic parameters were compared between propofol (n = 11) and remimazolam (n = 12) groups during the induction of general anaesthesia in patients undergoing non-cardiac surgery.

Well-Differentiated Adenocarcinoma Spreading Widely in the Gastric Submucosa.

A 56-year-old woman was referred to our hospital due to dry mouth. Diagnostic upper gastrointestinal endoscopy showed slightly elevated lesions both on the anterior wall and lesser curvature in the upper part of the stomach. Biopsy-proven tuble-forming atypical cells in the two lesions led us to treat the presumed early gastric cancers with endoscopic submucosal dissection (ESD).

Ulcer-forming colon cancer can develop cavity-forming metastatic lung tumors.

A 67-year-old man with abdominal pain and vomiting was referred to our hospital for the treatment of ileus. Enhanced computed tomography (CT) showed marked dilatation of the ileum and a presumed cecal tumor. After the intestinal decompression using nasogastric tube, a colonoscopy showed a type 3 tumor in the cecum.

Epithelioid Hemangioendothelioma of the Liver Showing Spontaneous Complete Regression after the Cessation of Methotrexate Intake.

A 71-year-old man with slight fever and dull abdominal pain was referred to our hospital. He had been receiving methotrexate (MTX) to treat his rheumatoid arthritis for more than 6 years but stopped taking MTX after admission due to the rapid aggravation of his liver function. Computed tomography (CT) showed multiple liver lesions with late enhancement, highly suggesting them to be cholangiocarcinomas.

Matrix-producing carcinoma of the breast showing retained rim enhancement to the late phase on magnetic resonance imaging.

A 54-year-old woman with a left breast mass was referred to our hospital. Mammography showed a mass, 2.1cm in size, with micro-lobulated boarders.
