BACKGROUND: Culture negative neutrocytic ascites is a variant of spontaneous bacterial peritonitis. But there are conflicting reports regarding the mortality associated with culture negativeneutrocytic ascites. Therefore we aim to determine the predictors of mortality associated with culture negativeneutrocytic ascites in a larger sample population. METHODS: We analysed 170 patients consecutively admitted to intensive care unit with diagnosis of culture negative neutrocytic ascites...

Dihydropyridine calcium-channel blockers are a known substrate for the cytochrome P450 isoform 3A4. Rifampicin, an antitubercular agent, is one of the most potent inducers of hepatic and intestinal CYP3A4 thus increasing dihydropyridine metabolism. We report a case of a 67-year-old hypertensive female treated with a 4-drug antihypertensive regimen including a dihydropyridine (nicardipine 50mg bid), who was admitted for septic arthritis of the knee requiring antibiotic treatment with teicoplanin 400mg od and rifampicin 600mg bid...

PURPOSE OF REVIEW: Monitoring of mental status and peripheral circulatory changes can be accomplished noninvasively in patients in the ICU. Emphasis on physical examination in conditions such as sepsis have gained increased attention as these evaluations can often serve as a surrogate marker for short-term treatment efficacy of therapeutic interventions. Sepsis associated encephalopathy and mental status changes correlate with worse prognosis in patients. Evaluation of peripheral circulation has been shown to be a convenient, easily accessible, and accurate marker for prognosis in patients with septic shock...

Subcutaneous fat necrosis of the newborn (SCFN) is a rare, self-limited disorder of the panniculus which appears in the first few weeks of life. SCFN generally follows an uncomplicated course. However, there are important complications for which the patient must be regularly monitored, including thrombocytopenia, hypoglycemia, hypertriglyceridemia, and most importantly, hypercalcemia. We report five infants with SCFN. All children were born at term. The onset of lesions was between 1 day and 20 days after birth...

REVIEW
E Schmutzhard, B Pfausler
Over the past decades, the incidence of sepsis and resultant neurologic sequelae has increased, both in industrialized and low- or middle-income countries, by approximately 5% per year. Up to 300 patients per 100 000 population per year are reported to suffer from sepsis, severe sepsis, and septic shock. Mortality is up to 30%, depending on the precision of diagnostic criteria. The increasing incidence of sepsis is partially explained by demographic changes in society, with aging, increasing numbers of immunocompromised patients, dissemination of multiresistant pathogens, and greater availability of supportive medical care in both industrialized and middle-income countries...

Sepsis-associated encephalopathy is a major complication during sepsis, and an effective treatment remains unknown. Although minocycline (MINO) has neuroprotective effects and is an attractive candidate for treating sepsis-associated encephalopathy, the effect of MINO on synaptic plasticity during sepsis is still unclear. In the present study, we investigated the effects of MINO on long-term potentiation (LTP) in the hippocampus in a cecal ligation and puncture (CLP) mouse model. We divided mice into 4 groups; (1) sham + vehicle, (2) sham + MINO (60 mg/kg, i...

BACKGROUND: Sepsis-associated encephalopathy (SAE) is a frequent and nasty complication of sepsis, associated with patients increased risk of death and long-term brain dysfunctions. OBJECTIVE: This study aimed to explore the effect of dexmedetomidine (Dex), an anesthetic adjuvant, on the development of SAE. METHODS: Lipopolysaccharide (LPS, 10 mg/kg) was intraperitoneally injected to male BALB/c mice to induce sepsis. Dex (25 μg/kg) was given intraperitoneally immediately after LPS injection...

INTRODUCTION: Wernicke's encephalopathy (WE) is a neurological syndrome caused by thiamine deficiency, and clinically characterized by ophthalmoplegia, ataxia and acute confusion. In developed countries, most cases of WE have been seen in alcohol misusers. Other reported causes are gastrointestinal tract surgery, hyperemesis gravidarum, chronic malnutrition, prolonged total parenteral nutrition without thiamine supplementation, and increased nutrient requirements as in trauma or septic shock...

Sepsis-associated encephalopathy (SAE) is a common complication associated with poor prognosis in septic patients, but the underlying mechanism remains unclear. We hypothesized that disturbed neuregulin 1 (NRG1)-ErbB4 signaling in the parvalbumin interneurons was involved in sepsis-induced cognitive impairment in a mouse model of SAE. The SAE model was induced by cecal ligation/perforation (CLP). Animals were randomly divided into the following six groups: sham + vehicle group, sham + NRG1 group, CLP + vehicle group, CLP + NRG1 group, CLP + NRG1 + AG1478 (ErbB4 inhibitor) group, and CLP + minocycline group...

The purpose of this study is to test the hypothesis that the mammalian target of rapamycin (mTOR) signaling pathway might mediate neuroprotection in a mouse model of septic encephalopathy and also to identify the role of autophagy. Mice were subjected to cecal ligation and puncture (CLP) or a sham operation, and all 50 mice were randomly assigned to five groups: sham, CLP+ saline, CLP+ rapamycin (1, 5, 10 mg/kg) groups. Two weeks after the operation, Morris water maze was conducted for behavioral test; Nissl staining was used for observing glia infiltration; immunohistochemical staining and biochemical measures in hippocampi were performed to detect mTOR targets and autophagy indicators...

During the last two decades, septic encephalopathy (SE) was recognized as a clinically relevant problem with a high prevalence in patients at admission and during their hospital stay. SE is a condition associated with increased mortality and morbidity such as long-term cognitive impairment. Areas covered: This review illustrates the pathophysiology of sepsis-associated encephalopathy and encephalitis involving blood-brain-barrier dysfunction and neuroinflammation caused by endothelial and microglial activation by endogenous or pathogen-derived compounds, hypoxia by impaired microvascular regulation and septic shock as well as imbalance of neurotransmitters...

Sepsis results in unfettered inflammation, tissue damage, and multiple organ failure. Diffuse brain dysfunction and neurological manifestations secondary to sepsis are termed sepsis-associated encephalopathy (SAE). Extracellular nucleotides, proinflammatory cytokines, and oxidative stress reactions are associated with delirium and brain injury, and might be linked to the pathophysiology of SAE. P2X7 receptor activation by extracellular ATP leads to maturation and release of IL-1β by immune cells, which stimulates the production of oxygen reactive species...

OBJECTIVE: Confabulations are described as "a falsification of memory occurring in clear consciousness in association with an organically derived amnesia". We describe production of confabulations in long-term memory in a 51-year-old woman who do not present amnesic syndrome typically associated. The patient was admitted in reanimation unit for septic shock. After 8 days of coma, she presented signs of encephalopathy of Gayet-Wernicke, without cerebral damage on T1 MRI. OBSERVATIONS: At 6 months of acute episode, the patient presents a severe cognitive and behavioural dysexecutive syndrome, with impulsivity, perseverations and environmental dependency...

BACKGROUND: The TP53 gene, encoding tumour suppressor protein p53, is located on the short arm of chromosome 17 (17p). Patients with 17p deletion (del17p) chronic lymphocytic leukaemia have poor responses and survival after chemoimmunotherapy. We assessed the activity and safety of ibrutinib, an oral covalent inhibitor of Bruton's tyrosine kinase, in relapsed or refractory patients with del17p chronic lymphocytic leukaemia or small lymphocytic lymphoma. METHODS: We did a multicentre, international, open-label, single-arm study at 40 sites in the USA, Canada, Europe, Australia, and New Zealand...

Nitric oxide (NO) overproduction via induction of inducible nitric oxide synthase (iNOS) is implicated in vasodilatory shock in sepsis, leading to septic encephalopathy and accelerating cerebral ischemic injury. An abbreviated urea-cycle (l-citrulline-l-arginine-NO cycle) has been demonstrated in cerebral perivascular nitrergic nerves and endothelial cells but not in normal cerebral vascular smooth muscle cell (CVSMC). This cycle indicates that argininosuccinate synthase (ASS) catalyzes l-citrulline (l-cit) conversion to form argininosuccinate (AS), and subsequent AS cleavage by argininosuccinate lyase (ASL) forms l-arginine (l-arg), the substrate for NO synthesis...

Septic encephalopathy is a form of general cerebral dysfunction caused by a systemic inflammatory reaction. Its investigation encounters enormous difficulties for the lack of reliable biological markers of neuronal lesions and methods for the evaluation of consciousness in severely ill patients. Hence, the importance of correct clinical interpretation of the character and magnitude of CNS activity. Examples are presented demonstrating the difficulty of interpreting disorders in CNS activity associated with evere community-acquired pneumonia...
