Objectives: During temporary abdominal closure (TAC) with damage control laparotomy (DCL), infusion volume and negative-pressure wound therapy (NPWT) output volume are associated with the success and prognosis of primary fascial closure. The same may also hold true for anastomosis. The aim of this research is to evaluate whether the difference between early anastomosis and delayed anastomosis in DCL is related to infusion volume and NPWT output volume.

Background: The current report describes a case of stomach perforation, a rare but serious complication, that occurred during cardiopulmonary resuscitation following severe cibenzoline intoxication.

Case Presentation: A woman aged in her 30s was brought into our hospital while receiving cardiopulmonary resuscitation for pulseless electrical activity. After starting extracorporeal membrane oxygenation (ECMO), her abdominal X-ray examination revealed free air in her abdomen.

Direct hemoperfusion with polymyxin B-immobilized fiber (PMX-DHP) has been widely used for severe sepsis and septic shock. However, data are limited regarding the clinical experience and efficacy of PMX-DHP for septic shock resulting from urinary tract infection (UTI). At our institution, 15 patients with septic shock resulting from a UTI received PMX-DHP from January 2013 to July 2017.

Stent migration, which causes issues in stent therapy for esophageal perforations, can counteract the therapeutic effects and lead to complications. Therefore, techniques to regulate stent migration are important and lead to effective stent therapy. Here, in these cases, we placed a removable fully covered self-expandable metallic stent (FSEMS) in a 52-year-old man with suture failure after surgery to treat Boerhaave syndrome, and in a 53-year-old man with a perforation in the lower esophagus due to acute esophageal necrosis.

Recent successive reports on acute pancreatitis-induced thrombotic thrombocytopenic purpura (TTP) have revealed that TTP-related microvascular damage is an aggravating factor of acute pancreatitis. Here, we report the case of a 26-year-old man diagnosed with acute pancreatitis due to high alcohol consumption. The patient was unconscious as he had taken an overdose of medication, and presented with fever and renal failure due to acute pancreatitis on admission.

In recent years, it has been reported that the urinary level of Liver-type fatty acid-binding protein (L-FABP) serves as a useful biomarker for diagnosing acute kidney injury (AKI) or sepsis complicated by AKI. However, because the urinary level of L-FABP is currently measured by enzyme-linked immunosorbent assay (ELISA), several days may elapse before the results of the measurement become available. We have newly developed a simplified kit, the Dip-test, for measuring the urinary level of L-FABP.

The application of endotoxin adsorption therapy for severe acute cholangitis is controversial. We present a survival case of septic shock and multiple organ failure due to severe acute cholangitis. The patient was treated by endotoxin adsorption therapy using polymyxin B-immobilized fiber because he continued to remain in shock even after successful endoscopic nasobiliary drainage.

The endotoxin activity assay (EAA) is a FDA-approved blood endotoxin assay that is reported as a useful tool for the diagnosis of gram-negative bacterial infection. However, discrepancies between the results of the EAA and those of the limulus amebocyte lysate (LAL) assay have been reported. Thus, we verified these methods.

Purpose: The purpose of this study was to investigate the relationship between the blood levels of interleukin (IL)-18 measured in the early stage of acute respiratory failure and the prognosis for patient survival.

Methods: The study subjects were 38 patients with acute respiratory failure treated at our institution during the 4-year period from April 2004 to March 2008. The underlying clinical condition was defined as acute respiratory distress syndrome (ARDS; n = 12) or acute lung injury (ALI; n = 26).

Tight glucose control (TGC) using a sliding scale based on intermittent blood glucose measurements occasionally can have a fatal outcome as a result of insulin-induced hypoglycemia. The present study was undertaken to examine whether the use of an artificial pancreas to achieve TGC would be possible in postoperative patients with sepsis. The retrospective study was carried out as an exploratory study, focusing on the possibility of precise evaluation of the significance of TGC as a beneficial intervention by serological monitoring of various mediators.

CD14 is present in macrophage, monocyte, and granulocyte cells and their cell membranes, and it is said to be responsible for intracellular transduction of endotoxin signals. Its soluble fraction is present in blood and is thought to be produced in association with infections. It is called the soluble CD14-subtype (sCD14-ST), and in the following text it is referred to by its generic name, presepsin.

Article Synopsis
  • A 36-year-old woman with sarcoidosis and Sjogren's syndrome was treated for pain but later experienced severe abdominal pain and distention, leading to her emergency admission.
  • Imaging revealed free air in her abdomen, prompting an emergency laparotomy which discovered multiple perforations in her transverse colon.
  • The case emphasizes the risks of using slow-release NSAIDs and corticosteroids in patients with autoimmune diseases, as this combination could worsen intestinal issues.

Background: There is a report that S100A12 is useful as an early marker of acute lung injury (ALI). The purpose of this study was to determine whether S100A12 or sRAGE is useful as a marker during the development of ALI in postoperative sepsis patients.

Methods: The subjects were patients who underwent emergency surgery because of sepsis secondary to perforation of the lower gastrointestinal tract.

The purpose of this study was to assess lipopolysaccharide (LPS)-stimulated cytokine production in the presence of linezolid (LZD) in comparison with the drug effect on the plasma endotoxin level. Peripheral venous whole-blood samples collected from five healthy subjects were stimulated with 10 microg/ml of LPS. LZD was then added to the LPS-stimulated blood samples at concentrations of 0, 2, 4, and 15 microg/ml , followed by incubation for 24 h at 37 degrees C in a 5% CO(2)-95% air atmosphere.

Sivelestat sodium hydrate (sivelestat) is a selective inhibitor of polymorphonuclear leukocyte elastase (PMN-E). We administered sivelestat to patients with septic acute lung injury (ALI) to examine its usefulness. The primary endpoints in the study were the duration of artificial ventilation and pulmonary oxygenation ability, and the secondary endpoints were mortality and the concentrations of PMN-E, SP-D, TNF-alpha and IL-8 in blood.

A 55-year-old (163 cm, 70 kg) man with traumatic intra-abdominal bleeding underwent emergency operation. The patient was in a state of hemorrhagic shock with 82 mmHg of systolic blood pressure (SBP) at hospital arrival. His condition became severer within about 1 hr, and tracheal intubation and mechanical ventilation were consequently started in the ambulatory emergency room.

Because of its low sensitivity, the conventional measurement method for endotoxin (ET) is not the most appropriate for monitoring the effect of ET adsorption therapy. Thus, the efficacy of ET adsorption therapy was investigated using a newly developed high-sensitivity ET assay method. The changes in the cytokine production capacity of whole blood were also examined.

Unlabelled: It is important to take into consideration the duration for which the plasma concentration of the drug is higher than the Minimal Inhibitory Concentration during treatment with carbapenem antibiotics, because the antibiotics are time-dependent drugs. A preliminary study of the administration of carbapenem antibiotics on the basis of the pharmacokinetics/pharmacodynamics (PK/PD) was conducted.

Subjects: Ten patients with intraabdominal infection.

CD14, a high-affinity receptor for lipopolysaccharide (LPS), is a glycoprotein expressed on the surface membranes of monocytes/macrophages. We have identified a previously unknown form of soluble CD14, named soluble CD14 subtype (sCD14-ST), that is increased in patients with sepsis. To measure sCD14-ST concentrations in plasma, we prepared anti-sCD14-ST antibodies and developed an enzyme immunoassay (EIA) for this soluble form of CD14.

Purpose: To examine the changes in blood-soluble phospholipase A(2)-IIA levels caused by surgical stress and postoperative infections.

Methods: We retrospectively analyzed a prospective database of 40 patients who underwent esophagectomy for esophageal cancer. Nine of these patients had a postoperative infection (E Inf(+) group), and 31 did not have a postoperative infection (E Inf(-) group).
