Local recurrence of submucosal invasive colorectal cancer after endoscopic submucosal dissection revealed by copy number variation.

We report a case in which analysis of copy number variation revealed local recurrence of submucosal invasive colorectal cancer after curative endoscopic submucosal dissection (ESD). An 86-year-old man with a history of abdominoperineal resection of the rectum for rectal cancer underwent resection with ESD for early-stage sigmoid cancer 5 cm away from the stoma opening. At the same time, ileocecal resection was performed for advanced cecal cancer.

Robustness and resilience of supply chains during the COVID-19 pandemic.

Using a unique firm-level data set from Asia, this study examines what determined the robustness and resilience of supply chain links, that is, the ability of maintaining links and recovering disrupted links by substitution, respectively, when firms faced economic shocks due to the spread of the coronavirus disease (COVID-19). We find that a supply chain link was likely to be robust if the link was between a foreign-owned firm and a firm located in the foreign-owned firm's home country, implying that homophily on a certain dimension generates strong ties and thus supply chain robustness. We also find that firms with geographic diversity of customers and suppliers tended to increase their transaction volume with one partner while decreasing the volume with others.

Donor insemination for heterosexual couples: A practice in transition.

Donor insemination (DI) has long been the treatment of choice for severe male infertility among heterosexual couples. Since disclosing when offspring become adults provokes serious emotional issues, counselors are recommending early disclosure about the treatment. Furthermore, several countries have changed their policies on nonanonymous sperm donation, concerning the strong demand of donor information from the offspring.

Necrotizing fasciitis and septic shock due to streptococcal toxic shock syndrome in an elderly patient: A case report.

Streptococcal toxic shock syndrome (STSS) has a high mortality rate, and most patients die within a few days of onset. We report an elderly patient with STSS, necrotizing fasciitis and septic shock caused by group G streptococcus who was successfully treated with multidisciplinary therapy.

Neurogenic pulmonary edema caused by right insular cortex infarction.

We report a case of neurogenic pulmonary edema (NPE) caused by middle cerebral artery infarction involving the right insular cortex. Hyperactivity of the insular cortex, which regulates sympathetic function, can cause NPE. The NPE should be considered in the differential diagnosis of dyspneic patients with insular cortex infarction.

Smoking and drinking habits relating to development of ulcerative colitis in Japanese: A multicenter case-control study.

Background And Aim: The number of patients with ulcerative colitis (UC) has been increasing in Japan. To elucidate the risk factors for developing UC in Japan, a hospital-based case-control study was conducted. This study examined the association between smoking/drinking habits and UC onset in detail.

The efficacy and safety of a duckbill-type anti-reflux metal stent as the initial metal stent for distal malignant biliary obstruction in unresectable pancreatic cancer.

Background: The usefulness of duckbill-type anti-reflux metal stent (DMS) in self-expandable metal stent-naïve pancreatic cancer (PC) patients has not been well-studied. This study aimed to evaluate the efficacy and safety of DMS in such patients.

Methods: We analyzed consecutive patients with unresectable PC who received a covered metal stent (CMS) as the initial self-expandable metal stent at our institution.

Medical students and junior residents have five concerns about general medicine training, and senior residents and young academic generalists respond to these concerns. We hope that this paper will help to dispel some common concerns for those who wish to become specialists in general medicine.

Protective Role of Endothelial Fibulin-4 in Valvulo-Arterial Integrity.

Background Homeostasis of the vessel wall is cooperatively maintained by endothelial cells (ECs), smooth muscle cells, and adventitial fibroblasts. The genetic deletion of fibulin-4 () in smooth muscle cells () leads to the formation of thoracic aortic aneurysms with the disruption of elastic fibers. Although is expressed in the entire vessel wall, its function in ECs and relevance to the maintenance of valvulo-arterial integrity are not fully understood.

Hemorrhagic gastric ulcer in a patient with Behcet's disease successfully treated with infliximab.

Behcet's disease (BD) is a multisystem immune-mediated inflammatory disorder that occasionally involves the gastrointestinal tract. Reports on gastrointestinal involvement of BD are relatively rare, of which gastroduodenal involvement is particularly rare. Endoscopic features of gastroduodenal lesions are unknown, and treatment strategies have not been established.

Uterine rupture in the third trimester of a pregnancy subsequent to a cesarean section by transverse uterine fundal incision: A case report and literature review.

Cesarean section via a transverse uterine fundal incision is performed in patients with placenta previa to reduce blood loss. We describe a case of uterine rupture in a pregnant woman who previously underwent a cesarean section and recovered from cardiac arrest by multidisciplinary management.

Comparison of the effects of individual symptoms of gastroesophageal reflux disease co-existing functional dyspepsia on patients' daily lives: A prospective, observational study.

Background And Aim: Patients with gastroesophageal reflux disease (GERD) frequently also have functional dyspepsia (FD) symptoms, which impair their quality of life. However, the magnitude and characteristics of the effects of each symptom on daily life have been unclarified. Using multiple regression analysis, we aimed to clarify these questions.

Case of laryngeal venous malformations requiring repeated advanced airway management in the perioperative course.

Laryngeal venous malformations rarely but do cause airway obstruction resulting in life-threatening events. The perioperative airway management for the patients with them has not been well established. We suggest a strategy for laryngeal venous malformations management in the patients who undergo surgery in addition to planning for airway management.

A case of groove pancreatitis with duodenal stenosis successfully treated by endoscopic ultrasonography-guided pancreaticogastrostomy.

One of the reasons for groove pancreatitis is caused by the leakage of pancreatic juice into the space between the pancreatic head, descending duodenum, and common bile duct. Endoscopic drainage of Santorini's duct (SD) via the minor papilla is reportedly efficacious but can be difficult due to duodenal stenosis. We report Santorini's duct drainage using endoscopic ultrasonography-guided pancreaticogastrostomy (EUS-PGS) for a case of groove pancreatitis with gastric outlet obstruction.

Procedural Outcomes After Percutaneous Coronary Interventions in Focal and Diffuse Coronary Artery Disease.

Background Coronary artery disease (CAD) patterns play an essential role in the decision-making process about revascularization. The pullback pressure gradient (PPG) quantifies CAD patterns as either focal or diffuse based on fractional flow reserve (FFR) pullbacks. The objective of this study was to evaluate the impact of CAD patterns on acute percutaneous coronary intervention (PCI) results considered surrogates of clinical outcomes.
