Objective Left ventricular outflow tract (LVOT) obstruction is a complication in 15-25% of patients with Takotsubo cardiomyopathy and sometimes leads to catastrophic outcomes, such as cardiogenic shock or cardiac rupture. However, the underlying mechanisms have not been clarified. Methods and Results We experienced 22 cases of Takotsubo cardiomyopathy during 3 years, and 4 of these 22 cases were complicated with LVOT obstruction in the acute phase (mean age 79±5 years, 1 man, 21 women). The LVOT pressure gradient in the acute phase was 100±17 mmHg...

We present a case of intramural duodenal haematoma caused by inferior vena caval (IVC) filter strut perforation requiring innovative open and endovascular retrieval. A 32-year-old woman presents in shock with dull epigastric pain and non-bilious vomiting. She had previously had an IVC filter for deep venous thrombosis and pulmonary embolism. Computed tomography demonstrated strut perforation into the second part of the duodenum, causing intramural haematoma and duodenal obstruction. Laparotomy facilitated evacuation of the duodenal haematoma, while the IVC filter was retrieved by endovascular means...

Sabine Brandt, Peter R Mertens
Kidneys undergoing acute inflammatory responses are characterized by cell infiltration and a cytokinergic milieu. The hazard resides in the perpetuation of inflammation and ensuing fibrosis. In this issue of Kidney International, Wang et al.(4) identify the cold shock Y-box binding protein-1 as the key orchestrator of cell infiltration in experimental tubulointerstitial nephritis following ureteral obstruction. Intriguingly, a small molecule previously designed to interfere with Y-box binding protein-1 interactions mediates an anti-inflammatory response and halts fibrogenesis...

The aim of the present study was to analyze in vivo the role of SNAI1 on renal fibrosis. Unilateral ureteral obstruction injury was induced in Snai1 knockout mice. Snai1 gene deletion was, however, only partial and could therefore not be correlated to reduced fibrosis. Expression of SNAI1 protein and epithelial-mesenchymal transformation markers was then assessed in human chronic allograft nephropathy biopsy specimens. Significant up-regulation of SNAI1 protein was detected within cytoplasm of proximal tubules localized, for some of them, near foci of fibrosis and tubular atrophy...

This report describes a case of endovascular repair of an outflow cannula obstruction in a heart failure patient with biventricular assist devices. The patient presented with cardiogenic shock and was diagnosed via multimodality imaging with outflow cannula obstruction of the left ventricular assist device, likely from a hematoma. A transesophageal echocardiogram-guided endovascular approach was undertaken. A 10.0 mm × 38 mm covered stent was successfully deployed and post-dilated. Normal flow in the outflow cannula was restored...

PURPOSE OF REVIEW: The urinary tract is the infection site in severe sepsis/septic shock in 10-30%. RECENT FINDINGS: There is a new Sepsis definition focusing on severe sepsis. Urosepsis is mainly due to obstructed uropathy of the upper urinary tract. The pathogenesis of sepsis is complex and is driven by the innate immune system. In the further course immunosuppression is developing.Management of urosepsis includes early diagnosis, early initiation of treatment such as identification and control of the complicating factor in the urinary tract and the specific sepsis therapy...

A 15-year-old girl with Graves' disease presented with hypotension after methimazole and propranolol were re-started for hyperthyroidism. She was found to have pulmonary artery hypertension resulting in obstructive shock. Thyroid storm was diagnosed according to Burch and Wartofsky score. She was promptly treated with anti-thyroid drugs, inorganic iodide, corticosteroid, and respiratory support. Pulmonary hypertension was treated with inhaled nitric oxide until the clinical status improved. Propranolol was withdrawn due to poor cardiac function...

Adult necrotising enterocolitis secondary Clostridium perfringens type C-pig-bel disease-is rarely seen outside of Pacific populations, with the highest incidence being in Papau New Guinea. We present the first reported case of pig-bel disease in a previously well patient without diabetes following food poisoning since 1996. In this case, the enterotoxin-induced disease necessitated emergency laparotomy and bowel resection following the failure of medical treatment and worsening septic shock. We hypothesise that obstruction secondary to a sigmoid diverticular stricture complicated by infection-related oedema led to colonic stasis and rapid progression of disease and bowel loss...

INTRODUCTION: Emphysematous pyelonephritis (EPN) is a rare and severe, necrotizing infection of the kidney. Diagnosis should be precocious based on computed tomography (CT). Its management remains controversial and its treatment is currently increasingly conservative. The aim of this paper is to discuss the conservative treatment of this disease through our experience in 21 patients. MATERIAL AND METHODS: A retrospective analysis including 21 patients managed conservatively for an emphysematous pyelonephritis in our department from January 2010 to April 2015...

Our aim was to determine short and medium-term changes of neutrophil gelatinase-associated lipocalin (NGAL) in the urine of patients undergoing shock wave lithotripsy (SWL). In patients with kidney stones, serum urea and creatinine (Cr), urine Cr and NGAL levels were determined immediately before and at 3, 24 h and 30 days after SWL. Urine NGAL concentrations were normalized to urinary Cr ruling out the confounding effect of variable hydration states. Thirty-five patients with a single renal stone were enrolled...

Manu Tandan, Rupjyoti Talukdar, Duvvur Nageshwar Reddy
Pancreatolithiasis, or pancreatic calculi (PC), is a sequel of chronic pancreatitis (CP) and may occur in the main ducts, side branches or parenchyma. Calculi are the end result, irrespective of the etiology of CP. PC contains an inner nidus surrounded by successive layers of calcium carbonate. These calculi obstruct the pancreatic ducts and produce ductal hypertension, which leads to pain, the cardinal feature of CP. Both endoscopic therapy and surgery aim to clear these calculi and decrease ductal hypertension...

PURPOSE: This study aimed to investigate the clinical effects of early goal-directed therapy according to the global end-diastolic volume index (GEDI) on chronic obstructive pulmonary disease (COPD) patients with septic shock. METHODS: A total of 71 COPD patients with septic shock were randomly assigned to 2 groups. In the control group (n = 37), fluid resuscitation was performed based on the central venous pressure. In the study group (n = 34), fluid resuscitation was performed until GEDI reached 800 mL/m(2)...

Hepatic ischemia-reperfusion injury as a result of inflow obstruction is a major cause of morbidity and mortality associated with liver pathologies and surgery. Heat shock proteins, a family of stress-inducible proteins involved in maintaining cell homeostasis and regulating the immune system play a major role in liver regeneration. They serve as crucial indicators of ischemia-reperfusion injury in human liver and influence liver function and recovery. The primary objectives of this article are to review the potential role of heat shock proteins as a diagnostic marker for liver diseases and therapeutic target in critical illness...

LPS stimulation in macrophages/monocytes induces TNFα production. We here tested the potential effect of GSK621, a novel AMP-activated protein kinase (AMPK) activator, against the process. In RAW264.7 macrophages, murine bone marrow-derived macrophages (BMDMs), and chronic obstructive pulmonary disease (COPD) patients' monocytes, GSK621 significantly inhibited LPS-induced TNFα protein secretion and mRNA synthesis. Inhibition of AMPK, through AMPKα shRNA knockdown or dominant negative mutation (T172A), almost abolished GSK621's suppression on TNFα in RAW264...
