Laparoscopic Repair of Internal Hernia at the Pelvic Floor After Low Anterior Resection: A Case Report.

Internal hernia following colorectal surgery is an uncommon but serious complication. Most reported cases have involved hernias resulting from mesenteric defects after left-sided colon resection. We herein report a case of laparoscopic repair of an internal hernia at the pelvic floor following low anterior resection.

New Treatment Modalities for Colorectal Cancer Through Simultaneous Suppression of FSP1 and GPX4.

Background/aim: Ferroptosis is a nonapoptotic type of cell death that is dependent on iron and involves the accumulation of reactive oxygen species. Ferroptosis suppressor protein 1 (FSP1) and glutathione peroxidase 4 (GPX4) are ferroptosis regulators that inhibit ferroptosis through independent pathways. This study assessed the prognostic value of GPX4 and FSP1 expression in colorectal cancer (CRC).

Practical use of transanal decompression tube following the repair of fourth-degree perineal tears associated with vaginal delivery.

Background: Fourth-degree perineal tears associated with vaginal delivery (PTAVD) occur in approximately 0.25 to 6% of vaginal deliveries. A persistent challenge in treating fourth-degree PTAVD is the high incidence of anastomotic leakage, leading to impaired quality of life, marked by incontinence, rectovaginal fistula, and painful sexual intercourse.

Appendiceal Metastasis of Breast Cancer: A Case Report and a Literature Review.

Appendiceal metastases of breast cancer (BC) are very rare, and there are few reports of resection. Asymptomatic appendiceal enlargement is often suspected to be a primary appendiceal tumor, making it difficult to suspect metastatic tumors, especially metastases from BC. On the other hand, advances in drug therapy, including hormonal therapy for BC, have prolonged survival, and there is a possibility of encountering metastatic cases that have rarely been seen before.

Acute gastric dilatation with segmented abdominal paresis as a rare manifestation of herpes zoster: a case report and review of the literature.

Background: Herpes zoster is a common disease that can affect men and women at any age. Sensory neuropathy is the most common complication while motor neuropathy of the abdominal muscles is rare complication appearing in ~ 0.7% of patients.

Diagnosis and treatment of cardiovascular disease in patients with heritable connective tissue disorders or heritable thoracic aortic diseases.

Patients with heritable connective tissue disorders (HCTDs), represented by Marfan syndrome, can develop fatal aortic and/or arterial complications before age 50. Therefore, accurate diagnosis, appropriate medical treatment, and early prophylactic surgical treatment of aortic and arterial lesions are essential to improve prognosis. Patients with HCTDs generally present with specific physical features due to connective tissue abnormalities, while some patients with heritable thoracic aortic diseases (HTADs) have few distinctive physical characteristics.

Asymptomatic Essential Thrombocytosis Presenting with Extrahepatic Portal Vein Thrombosis: A Case Report.

BACKGROUND Essential thrombocytosis (ET) is a myeloproliferative neoplasm variant that leads to excessive platelet production in the bone marrow. Janus kinase 2 (JAK2) mutation is observed in 60% of ET cases. The risk of thrombosis increases with the presence of this mutation.

Association Between Genetic Diagnosis and Clinical Outcomes in Patients With Heritable Thoracic Aortic Disease.

Background Differences in the clinical course of heritable thoracic aortic disease based on the disease-causing gene have not been fully evaluated. To clarify the clinical relevance of causative genes in heritable thoracic aortic disease, we assessed the clinical course of patients categorized based on genetic diagnosis. Methods and Results We investigated cardiovascular events and mortality in 518 genetically diagnosed patients in 4 groups: Group 1, (n=344); Group 2, , , , or (n=74); Group 3, (n=60); and Group 4, or (n=40).

Characteristics, Antithrombotic Patterns, and Prognostic Outcomes in Claudication and Critical Limb-Threatening Ischemia Undergoing Endovascular Therapy.

Purpose: The underlying difference between intermittent claudication (IC) and critical limb-threatening ischemia (CLTI) still remains unclear. This prospective multicenter observational study aimed to clarify differences in clinical features and prognostic outcomes between IC and CLTI, and prognostic factors in patients undergoing endovascular therapy (EVT).

Materials And Methods: A total of 692 patients with 808 limbs were enrolled from 20 institutions in Japan.

Risk factors for recurrence in elderly patients with stage II colorectal cancer: a multicenter retrospective study.

Background: Adjuvant chemotherapy for stage II colorectal cancer (CRC) is considered appropriate for patients with risk factors for recurrence, rather than for all patients uniformly. However, the risk factors for recurrence remain controversial, and there is limited information, especially for elderly patients. The Geriatric Nutritional Risk Index (GNRI) is widely used as a simple nutritional screening tool in the elderly and is associated with cancer prognosis and recurrence.

Activation of PPARγ in bladder cancer via introduction of the long arm of human chromosome 9.

Bladder cancer is divided into two molecular subtypes, luminal and basal, which form papillary and nodular tumors, respectively, and are identifiable by gene expression profiling. Although loss of heterozygosity (LOH) of the long arm of human chromosome 9 (9q) has been observed in the early development of both types of bladder cancer, the functional significance of LOH remains to be clarified. The present study introduced human chromosome 9q into basal bladder cancer cell line, SCaBER, using microcell-mediated chromosome transfer to investigate the effect of LOH of 9q on molecular bladder cancer subtypes.

Phlegmonous gastritis: a case series.

Background: Phlegmonous gastritis is a rare and fatal infectious disease of the stomach, presenting varied and nonspecific endoscopic images, which are therefore difficult to diagnose. This report discusses three cases of phlegmonous gastritis, each with unique endoscopic images, and considers the differential diagnosis of this disease. These cases were initially suspected of scirrhous gastric cancer, gastric syphilis, and acute gastric mucosal lesion.

Human chromosome 3p21.3 carries TERT transcriptional regulators in pancreatic cancer.

Frequent loss of heterozygosity (LOH) on the short arm of human chromosome 3 (3p) region has been found in pancreatic cancer (PC), which suggests the likely presence of tumor suppressor genes in this region. However, the functional significance of LOH in this region in the development of PC has not been clearly defined. The human telomerase reverse transcriptase gene (hTERT) contributes to unlimited proliferative and tumorigenicity of malignant tumors.

Clinical Significance of Serum Antithrombin III Activity After Hepatectomy for Hepatocellular Carcinoma.

Background: As antithrombin III (AT-III) is produced in the hepatocytes, its serum activity decreases at the time of liver failure, in addition to ischemia reperfusion injury, vascular endothelial dysfunction, and disseminated intravascular coagulation (DIC). Here, we examined whether the serum AT-III value after hepatectomy could be a prognostic factor for hepatocellular carcinoma (HCC).

Methods: Of 141 patients who underwent hepatectomy for HCC, data for 101 patients in whom serum AT-III activity was measured on the first postoperative day were extracted.

The prognostic significance of combined geriatric nutritional risk index and psoas muscle volume in older patients with pancreatic cancer.

Background: The geriatric nutritional risk index (GNRI), originally developed as a nutritional assessment tool to evaluate mortality and morbidity in older hospitalized patients (i.e., those aged ≥65 years), is regarded as a prognostic factor in several cancers.

Rationale and Design of a Prospective, Multicenter, Single-Arm Clinical Trial to Investigate the Safety and Effectiveness of Rotablator Atherectomy System as an Adjunctive Device for Endovascular Treatment of Occlusive Atherosclerotic Lesions in Below-the-Knee Arteries With Critical Limb Ischemia (RESCUE-BTK).

Endovascular treatment with balloon angioplasty plays a major role in revascularization of below-the-knee (BTK) arteries in patients with critical limb ischemia (CLI). However, with severely calcified lesions, achieving optimal revascularization with balloon angioplasty alone is difficult. Therefore, we are evaluating the safety and effectiveness of the Rotablator atherectomy system as an adjunctive device in the treatment of severely calcified lesions in BTK arteries in the RESCUE-BTK trial, a multicenter, single-arm, open-label, exploratory investigator-initiated clinical study of medical devices.
