Women With Acute Aortic Dissection Have Higher Prehospital Mortality Than Men.

Background: Acute aortic dissection (AAD) often leads to out-of-hospital cardiac arrest (OHCA) and death before hospital arrival.

Objectives: The purpose of this study was to investigate differences in AAD incidence by sex.

Methods: A population-based study in a city with 121,180 residents was conducted using postmortem computed tomography data to identify patients with AAD who died before hospital arrival in 2008-2020.

Retroperitoneoscopic Simple Nondismembered Pyeloplasty with Da Vinci Si Assistance to Prevent Alignment Shift.

Retroperitoneoscopic simple nondismembered pyeloplasty (SNDP) with da Vinci Si assistance was developed because of a possible risk for alignment shift after retroperitoneoscopic diamond-shaped bypass pyeloplasty (Diamond-Bypass; DP). Outcomes of SNDP and DP were compared. For SNDP, a small longitudinal incision is made on the border of the dilated pelvis and narrowed ureter at the ureteropelvic junction (UPJ).

Comparative assessment of fully laparoscopic Duhamel-Z with minimal rectorectal dissection vs. laparoscopy-assisted Duhamel-Z with blunt manual rectorectal dissection for total colonic aganglionosis.

Aims: Early postoperative outcome (EPO) was compared between fully laparoscopic Duhamel-Z (F-Dz) and laparoscopy-assisted Duhamel-Z (A-Dz) anastomoses performed for total colonic aganglionosis (TCA).

Methods: EPO was assessed quarterly for the first year after F-Dz/A-Dz using a continence evaluation score (CES) based on stool frequency (motions/day) and stool consistency (0 = liquid, 1 = soft, 2 = formed), presence of anal erosion (0 = severe, 1 = moderate, 2 = mild), and incidence of enterocolitis.Surgical technique involved taking the ileostomy down, dissecting the colon laparoscopically, and preparing the pull-through ileum through the stoma wound.

Robot-Assisted Retroperitoneoscopic Diamond Bypass Pyeloplasty.

Aim: Robot (da Vinci Si; Intuitive Surgical, Sunnyvale, CA) assisted retroperitoneoscopic diamond bypass pyeloplasty (R-RDBP) performed for ureteropelvic junction (UPJ) obstruction (n = 5) is presented.

Methods: Patients were placed affected side up and the retroperitoneal space accessed conventionally using 3-4 trocars. The diamond-shaped anastomosis involved incising the lowest part of the renal pelvis 12-15 mm transversely and the ureter distal to the obstruction 10-12 mm longitudinally.

Combined laparoscopic and thoracoscopic approaches for Bochdalek hernia with hernia sac in an 8-years-old boy: Case report.

Bochdalek hernia (BH) is characterized by a defect of the posterolateral diaphragm and intrathoracic herniation of abdominal organs. The laparoscopic or thoracoscopic approach has recently become the surgical standard. However, studies on combined approaches are limited.

Testicular appendage torsion in children.

Background: Testicular appendage torsion (TAT) is a medical emergency that presents as an acute scrotum, usually in children and preadolescents. In previous reports of TAT, most cases have been treated conservatively, but some necessitate surgical treatment. Our aim was to examine the incidence, clinical examination findings, etiology, and treatment of TAT.

Umbilical microflora and pediatric surgery.

Introduction: In pediatric surgery, the umbilicus with humid environment prone to bacterial colonization has become the most common site of entrance into the peritoneum. However, the umbilical flora in children has never been reported. This study aimed to describe the characteristics of umbilical microflora in children before antiseptic skin preparation.

Defined serum-free culture of human infant small intestinal organoids with predetermined doses of Wnt3a and R-spondin1 from surgical specimens.

Purpose: Refinement of organoid technology is important for studying physiology and disease of the intestine. We aimed to optimize defined serum-free conditions for human infant small intestinal (SI) organoid culture with predetermined doses of Wnt3a and Rspo1 from surgical specimens. We further assessed whether intestinal specimens could be stored before use as a source of organoids.

Association of early administration of furosemide with improved oxygenation in patients with acute heart failure.

Aims: Optimal pharmacological treatment for chronic heart failure has been established. However, treatments that can improve the prognosis of acute heart failure (AHF) are controversial. Although intravenous diuretics may be one optimal treatment option, little evidence has shown the effect of early administration of diuretics on clinical outcomes in patients with AHF.

Disseminated carcinomatosis of the bone marrow from rectal cancer: A case report.

A 66-year-old man presented with worsening dyspnea. A colonoscopy revealed an elevated lesion at the rectosigmoid junction. The biopsy specimen and bone marrow aspiration demonstrated adenocarcinoma, leading to a diagnosis of disseminated carcinomatosis of the bone marrow.

Perforation in pediatric non-complicated appendicitis treated by antibiotics: the real incidence.

Purpose: The incidence of perforation during antibiotic therapy (AT) of children triaged as non-complicated acute appendicitis (NC-Ap) was investigated.

Methods: Abdominal ultrasonography (US) and/or computed tomography (CT) scans from cases of perforation identified at appendectomy for failed AT were reassessed blindly by a panel of board-certified specialists for any evidence of pre-AT morbidity suggestive of perforation.

Results: Of 521 cases triaged as NC-Ap, symptoms resolved with AT in 452 cases (86.

Signet-ring Cell Carcinoma in Hyperplastic Polyp of the Stomach.

Signet-ring cell carcinoma rarely occurs in gastric hyperplastic polyps, with only a few such cases reported. We treated a 76-year-old woman with a signet-ring cell carcinoma arising from a hyperplastic polyp. She had been diagnosed with a gastric hyperplastic polyp four years previously.

Efficacy and safety of double filtration plasmapheresis in combination with interferon therapy for chronic hepatitis C.

Aim: Efficacy and safety of double filtration plasmapheresis (DFPP) for chronic hepatitis C were prospectively analyzed in Japanese clinical settings.

Methods:  All patients who received DFPP in combination with interferon (IFN) therapy for chronic hepatitis C were serially recruited at 36 institutions between April 2008 and July 2009 in Japan.

Results:  A total of 239 patients were analyzed for the safety of DFPP and 206 patients for the efficacy.
