Article Synopsis
  • This study evaluated how effective diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) quantification are in diagnosing acute appendicitis in patients with right lower abdominal pain.
  • A total of 51 patients were examined, and by combining DWI with traditional T2-weighted imaging (T2WI), the diagnostic accuracy for appendicitis increased significantly.
  • The results indicated that lower ADC values in both the appendix and peri-appendiceal tissue can help distinguish between uncomplicated and complicated appendicitis, achieving very high accuracy rates.

Background And Aim: Acute pancreatitis following balloon-assisted enteroscopy is a rare but serious complication. The causative mechanism is uncertain and prevention strategies are not established. We conducted a retrospective study to clarify the risk factors for pancreatic hyperamylasemia.

A 33-year-old woman with Crohn disease complained of diarrhea and hematochezia from the fifth week of her third pregnancy and was hospitalized. Because her CDAI indicated 307.1 points and colonoscopy showed multiple longitudinal ulcers in the distal colon, adalimumab therapy was initiated.

Combined epidural and general anesthesia has become a standard anesthetic method for thymectomy. We employed levobupivacaine for epidural anesthesia combined with general anesthesia using remifentanil and sevoflurane for thymectomy with thoracoscopy for generalized type of myasthenia gravis. After decreasing the high level of antibodies to acethylcholine receptor by plasmapheresis, we could perform a stable and successful anesthetic management without the use of any muscle relaxants for the thymectomy.

Plasma diafiltration (PDF) is a blood purification therapy in which simple plasma exchange (PE) is performed using a selective membrane plasma separator while the dialysate flows outside the hollow fibers. A prospective, multicenter study was undertaken to evaluate the changes in bilirubin, IL-18, and cystatin C, as well as the 28-day and 90-day survival rates, with the use of PDF according to the level of severity as measured by the Model for End-Stage Liver Disease (MELD) score. Twenty-one patients with liver failure were studied: 10 patients had fulminant hepatitis and PDF therapies were performed 28 times; 11 had acute liver failure with the therapy performed 96 times.

Pneumatosis coli is a relatively rare condition characterized by the presence of gas in the submucosa or subserosa involving mainly the large intestine and, occasionally, the mesenteric attachments. We experienced two cases of pneumatosis coli with ulcerative colitis after colonoscopy that had different clinical courses. Case 1 showed submucosal pneumatosis coli and portal venous air.

Change in the pharmacokinetic disposition of an antifungal agent micafungin (MCFG) by 8-hour plasma exchange (PE) with 3200 mL replacement was examined in a stem cell transplant recipient. On pharmacokinetic analysis of the time course of the serum concentrations of MCFG, it was determined that PE shortened the elimination half-life of MCFG from 16.5 hours to 6.

Background And Aims: To measure the extended renal hemodynamic changes induced by intravenous radiocontrast.

Methods: Cross-ewes were studied in a randomized cross-over study. Intravenous saline or radiocontrast were administered, and continuous measurement of cardiac output and renal blood flow (RBF) was performed with flow probes.

Objective: To investigate the short- and medium-term renal hemodynamic and functional responses to both short and sustained hypoperfusion.

Subjects: Eleven Merinos ewes.

Setting: Animal laboratory of the University Physiology Institute.

Septic acute kidney injury accounts for close to 50% of all cases of acute kidney injury in the intensive care unit and, in its various forms, affects between 15% and 20% of intensive care unit patients. However, there is little we really know about its pathophysiology. Although hemodynamic factors might play a role in the loss of glomerular filtration rate, they may not act through the induction of renal ischemia.

A 49-year-old female cardiomyopathic patient with heart, hepatic, and renal failure and lactic acidosis was transferred to the intensive care unit without a unifying diagnosis. She was of short stature (145 cm tall), had difficulty in hearing, a past history of complete atrioventricular block, and had received a permanent pacemaker. She had been diagnosed and treated as dilated cardiomyopathy by her primary doctor.

Severe acute pancreatitis is a clinical entity that can develop into multiple organ failure (MOF), and still has a poor prognosis. It is generally agreed that excessive humoral mediators such as pro-inflammatory cytokines play important roles in the pathogenesis of organ failure in patients with severe acute pancreatitis (SAP). Furthermore, it has been reported that continuous hemodiafiltration (CHDF) can remove the excess humoral mediators during the hypercytokinemic state of systemic inflammatory response syndrome (SIRS).

The role of cross-sectional imaging in the diagnosis of Crohn disease has expanded with recent technologic advances in computed tomography (CT) and magnetic resonance (MR) imaging that allow rapid acquisition of high-resolution images of the intestines. To acquire images of diagnostic quality, administration of a fairly large amount of intraluminal contrast agent prior to examination and scanning with intravenous contrast material injection are necessary. Both CT and MR imaging are reported to have a sensitivity of over 95% for the detection of Crohn disease; however, they may not allow early diagnosis.

Acute lower gastrointestinal bleeding is a rare complication of Crohn's disease (CD). Although anti-tumor necrosis factor-alpha (TNF-alpha, infliximab) therapy has been established for patients with inflammatory and fistulous CD, there has been little evidence on whether infliximab is effective for the hemorrhagic type of CD. We report a case of a 31-year-old man with CD who had recurrent sudden-onset bloody stool.

Matrix metalloproteinases (MMPs) are the proteases involved in the degradation of the extracellular matrix. MMP-1 is thought to be one of the key enzymes in fibrolysis, a process closely related to tissue remodeling. In the present study, we investigated MMP-1 secretion from human pancreatic periacinar myofibroblasts in response to pro-inflammatory cytokines IL-1beta and TNF-alpha.

Objective: Although the pathogenesis of Crohn's disease remains unclear, dietary fat is thought to exacerbate intestinal inflammation. Chitosan is a water-insoluble dietary fiber, and a chitosan and ascorbic acid mixture has been shown in rats to increase fecal fat excretion without affecting protein digestibility. However, it remains unclear whether a chitosan and ascorbic acid mixture is safe and effective for patients with Crohn's disease.
