This disease is seen nearly exclusively in East Asian infants and children who had previously a good health. Serial MRI examinations demonstrated symmetric lesions involving the thalami, brainstem, cerebellum, and white matter. This disease has a poor prognosis, often culminating in profound morbidity and mortality. A 22-month infant with ANEC hospitalized in Amirkola Children Hospital has been evaluated. References1.

    Acute necrotizing encephalopathy of childhood is a rare disease with a broad clinical, radiologic, and biochemical spectrum. In the few postmortem studies published to date, the neuropathologic findings involved symmetric, necrotic brain lesions as the hallmark. Here we report on the clinical and neuropathologic findings of a Spanish child with the most severe form of the disease. PMID:18021928

  3. Concentric structure of thalamic lesions in acute necrotizing encephalopathy

    Acute necrotizing encephalopathy of childhood (ANE) is characterized by multiple, symmetrical brain lesions affecting the bilateral thalami, putamina and cerebral white matter, which often show a concentric structure on CT and MRI. To reveal the pathological substrate of this finding, comparison was made between CT and necropsy findings of three fatal cases of ANE. Cranial CT demonstrated a concentric structure of the thalamocerebral lesions in one patient who died 3.5 days after the onset of encephalopathy, but not in the other two patients who died within 30 h. Neuropathological examination of postmortem brains revealed laminar changes of vascular and parenchymal pathology in all the cases. Excessive permeability of blood vessels and resultant vasogenic edema became more prominent with increasing depth from the cerebral surface. The deep portion of the lesions showed severe perivascular hemorrhage, accounting for the central high density on the CT images of one patient. (orig.)

    Acute necrotizing encephalopathy of childhood (ANEC) is a disease entity seen nearly exclusively in East Asian children that is characterized by multifocal, symmetric lesions involving the thalami, brainstem, cerebellum, and white matter. We present a child who developed dramatic neurologic symptoms following a viral prodrome. Serial MRI examinations demonstrated characteristic lesions of ANEC, while laboratory analyses revealed evidence of acute infection with human herpesvirus-6 (HHV-6). We highlight the MRI findings in both the acute and convalescent phases of ANEC, discuss the implications of neuroimaging on the child's clinical course, and emphasize the integral role of the radiologist in correctly diagnosing this rare disease.

  7. Acute necrotizing encephalopathy of childhood: a fatal complication of swine flu

    Acute necrotizing encephalopathy of childhood (ANEC) is a rare condition characterized by the presence of multifocal symmetrical brain lesions involving mainly thalami, brainstem, cerebellum and white matter. ANEC is a serious and life threatening complication of simple viral infections. We present a case of a young child who developed this condition with classical clinical and radiological findings consistent with ANEC, secondary to swine flu (H1N1). He needed ventilatory support and had profound motor and intellectual deficit on discharge. We report this case with aim of raising awareness about this fatal complication of swine flu which has become a global health care issue these days. (author)

  8. Acute necrotizing encephalopathy in a child with H1N1 influenza infection

    Since the World Health Organization declared a global pandemic of novel influenza A H1N1 in June 2009, there has been a sustained rise in the number of cases of this strain of influenza. Although most cases are mild with complete and uneventful recovery, multiple cases of severe infection with complications including death have been reported. To the best of our knowledge, the majority of fatal outcomes in the United States have been related to pulmonary complications. We report a 12-year-old girl infected with influenza A H1N1 whose clinical course was complicated by rapid progressive neurologic deterioration and striking CT and MRI findings consistent with acute necrotizing encephalopathy (ANE). To our knowledge this has not been reported in the pediatric radiology literature. We hope this case will alert radiologists to this complication and familiarize radiologists with imaging findings that herald ANE. (orig.)

    Acute necrotizing encephalopathy (ANE) is a rare disease presenting with rapidly progressing encephalopathy. It usually occurs in otherwise healthy children after common viral infections. The hallmarks of ANE are the neuroradiological findings of multiple symmetric lesions in the thalami, midbrain, pons and brainstem. Most cases are sporadic and non recurrent. However, recurrent or familial forms of ANE due to mutations in RANBP2 gene have been reported. It has been suggested to give these cases the term ANE1. We report the clinical course in two male infants (P1, P2) with ANE1 and a variable clinical course and outcome. One patient is heterozygous for the most common RANBP2 missense mutation p.Thr585Met. In the other patient we observed a novel de novo missense mutation p.Trp681Cys in the RANBP2 gene causing recurrent ANE. Clinical and radiological features are presented and differential diagnoses are discussed. This report adds to the current knowledge of the phenotype in ANE, caused by mutations in RANBP2 gene.

    Acute necrotizing encephalopathy (ANE) is a rapidly progressive encephalopathy that can occur in otherwise healthy children after common viral infections such as influenza and parainfluenza. Most ANE is sporadic and nonrecurrent (isolated ANE). However, we identified a 7 Mb interval containing a susceptibility locus (ANE1) in a family segregating recurrent ANE as an incompletely penetrant, autosomal-dominant trait. We now report that all affected individuals and obligate carriers in this family are heterozygous for a missense mutation (c.1880C→T, p.Thr585Met) in the gene encoding the nuclear pore protein Ran Binding Protein 2 (RANBP2). To determine whether this mutation is the susceptibility allele, we screened controls and other patients with ANE who are unrelated to the index family. Patients from 9 of 15 additional kindreds with familial or recurrent ANE had the identical mutation. It arose de novo in two families and independently in several other families. Two other patients with familial ANE had different RANBP2 missense mutations that altered conserved residues. None of the three RANBP2 missense mutations were found in 19 patients with isolated ANE or in unaffected controls. We conclude that missense mutations in RANBP2 are susceptibility alleles for familial and recurrent cases of ANE. PMID:19118815

    Full Text Available A encefalopatia necrotizante aguda foi descrita inicialmente em crianças japonesas e se caracteriza por rápida evolução e lesões simétricas no tronco encefálico, cerebelo e especialmente nos tálamos. Avaliamos uma menina de 7 meses de idade, que apresentou dois episódios de depressão da consciência de rápida instalação e paresias, sem alterações metabólicas. Houve uma rápida melhora na primeira crise, porém o segundo episódio foi fulminante, tendo evoluído para estado de morte encefálica em dois dias. Os estudos de ressonância magnética mostraram lesões simétricas nos tálamos e acometimento também do tronco encefálico e cerebelo.Acute necrotizing encephalopathy was initially reported in Japanese children. The rapid evolution and symmetrical brain lesions seen in the brainstem, cerebellum and specially in the thalamus characterize the disease. We studied a 7-month-old-girl, who presented with two episodes of rapid loss of consciousness and paresis without metabolic disturbances. At the first time she had a rapid improvement, but at the second episode the course was fulminant and in two days she lapsed into a clinical state of brain death. The magnetic resonance studies showed symmetrical lesions in the thalamus and additional lesions involving the brainstem and the cerebellum.

    Full Text Available Carbon monoxide poisoning is a major cause of death following attempted suicide and accidental exposures. Although clinical presentation depends on the duration and the intensity of exposure, the assessment of the severity of intoxication is difficult. A small percentage of patients who show complete initial recovery may develop delayed neurological deficits. Delayed encephalopathy after acute carbon monoxide poisoning is a rare and poor prognosis neurologic disorders and there is no specific treatment. We present a case with early onset of delayed encephalopathy after acute carbon monoxide poisoning with typical cranial imaging findings in a child with atypical history and clinical presentation.

    Full Text Available Context Acute pancreatitis due to pancreatic ischemia is a rare condition. Case report In this case report we describe a 57-year-old male who developed an acute necrotizing pancreatitis after running a marathon and visiting a sauna the same evening, with an inadequate fluid and food consumption during both events. Conclusions Pancreatic ischemia imposed by mechanical and physical stress and dehydration can induce the development of acute pancreatitis. Separately, these factors are rare causes of ischemic acute pancreatitis. But when combined, as in this particular case, the risk of an acute necrotizing pancreatitis cannot be neglected

    Periorbital necrotizing fasciitis is a rare but potentially fatal infection. It is most commonly caused by Gram-positive group A b-haemolytic Streptococci and rarely by fungal infections. In this report, we present a rare case of periorbital necrotizing fasciitis caused by Aspergillus species in an immunocompromised patient. He presented to us with a history of a slowly progressive eyelid necrosis leading to a loss of vision in one eye. The patient was started on an antibiotic and subsequently, surgical debridement and enucle-ation were performed. A few days post-operatively, yellow white mould colonies were noted to grow on the wound surface. Microbiology cultures identified them as Aspergillus species and intravenous amphotericin B 10 mg was added daily. However, despite the extensive medical and surgical treatments, he failed to respond and succumbed from septicaemia and multi-organ failure.

  3. Antibiotics in acute necrotizing pancreatitis --- perspective of a developing country

    Prophylactic antibiotics in acute necrotizing pancreatitis is controversial. The mortality of acute necrotizing pancreatitis is 8-25% in the western world. In view of the limited resources available for managing the complications of infected pancreatitis in developing countries, the use of prophylactic antibiotics may be recommended in selected cases. Various antibiotics show good penetration into the pancreatic tissue; imipenem and quinolones have better penetration. Clinical trials on the use of prophylactic antibiotics in necrotizing pancreatitis have been reviewed. Prophylactic antibiotics have been considered if greater than 30% pancreatic necrosis as documented by CT scan. Imipenem can be given for a duration of 10 to 14 days if no systemic complications are present. In a developing country where the cost of managing complications of pancreatitis can be a limiting factor for patients, the use of prophylactic antibiotics early on in the disease in selected cases can be beneficial.

  4. Wernicke Encephalopathy Presenting in a Patient with Severe Acute Pancreatitis

    Ana Cecilia Arana-Guajardo

    2012-01-01

    Full Text Available Context Acute pancreatitis can lead to prolonged fasting and malnutrition. Many metabolic changes, including thiamine deficiency, may lead to the well know pancreatic encephalopathy. In this condition however the thiamine deficiency is rarely suspected. Case report We report the case of a 17-year-old woman with severe acute pancreatitis who developed mental status changes and ophthalmoplegia. A magnetic resonance image showed hyperintensive signals in periventricular areas, medial thalamus, and mammillary bodies, findings consistent with the diagnosis of Wernicke encephalopathy. Thiamine treatment reversed neurological complications. Conclusion Wernicke encephalopathy secondary to thiamine deficiency should be considered as a possible cause of acute mental status changes in patients with acute pancreatitis and malnutrition. Prophylactic doses of thiamine could be considered in susceptible patients.

  7. Percutaneous necrosectomy in patients with acute, necrotizing pancreatitis

    The objective of this retrospective study was to evaluate the outcome of patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy. By searching the radiological, surgical and internal medicine databases, all patients with acute necrotizing pancreatitis treated by active percutaneous necrosectomy between 1992 and 2004 were identified. Demographic, laboratory, and clinical data, and details about invasive procedures were collected by reviewing patient charts, radiological and surgical reports. The computed tomography severity index (CTSI) scores were determined by reviewing CT images. Eighteen patients were identified. Median Ranson score on admission was 2. The Acute Physiology and Chronic Health Evaluation (APACHE) II score was median 22. Median CTSI score was 7. Initially all patients were treated with CT-guided drainage placement. Because passive drainage proved not to be effective, subsequent minimally invasive, percutaneous necrosectomy was performed. Eight out of 18 patients recovered fully without the need for surgery. Ten of 18 patients required additional surgical necrosectomy. For one of ten patients, percutaneous necrosectomy allowed postponing surgery by 39 days. Four of ten surgically treated patients died: three from septic multiorgan failure, one from pulmonary embolism. Percutaneous minimally invasive necrosectomy can be regarded as a safe and effective complementary treatment modality in patients with necrotizing pancreatitis. It is suitable for a subset of patients to avoid or delay surgery. (orig.)

  9. Acute hyperammonemic encephalopathy with features on diffusion-weighted images: Report of two cases

    Acute hyperammonemic encephalopathy is a rare toxic encephalopathy caused by accumulated plasma ammonia. A few literatures are reported about MRI findings of acute hyperammonemic encephalopathy. It is different from the well-known chronic hepatic encephalopathy. The clinical symptom and MRI findings of acute hyperammonemic encephalopathy can be reversible with proper treatment. Acute hepatic encephalopathy involves the cingulate cortex, diffuse cerebral cortices, insula, bilateral thalami on diffusion-weighted imaging (DWI), and fluid-attenuated inversion-recovery. Acute hepatic encephalopathy might mimic hypoxic-ischemic encephalopathy because of their similar predominant involving sites. We experienced 2 cases of acute hyperammonemic encephalopathy consecutively. They showed restricted diffusion at the cingulate cortex, cerebral cortices, insula, and bilateral dorsomedial thalami on DWI. One patient underwent acute fulminant hepatitis A, the other patient with underlying chronic liver disease had acute liver failure due to hepatotoxicity of tuberculosis medication. In this report, we presented the characteristic features of DWI in acute hyperammonemic encephalopathy. In addition, we reviewed articles on MRI findings of acute hyperammonemic encephalopathy.

    Full Text Available Baking soda is a readily available household product composed of sodium bicarbonate. It can be used as a home remedy to treat dyspepsia. If used in excessive amounts, baking soda has the potential to cause a variety of serious metabolic abnormalities. We believe this is the first reported case of hemorrhagic encephalopathy induced by baking soda ingestion. Healthcare providers should be aware of the dangers of baking soda misuse and the associated adverse effects.

  13. About pathognomonic images: an infrequent case of acute encephalopathy

    Alessandro Grasso

    2013-05-01

    Full Text Available BACKGROUND The occurrence of acute encephalopathy is a dramatic clinical dilemma when usual diagnostic techniques (blood tests, cerebral CT and cerebrospinal fluid analysis show no abnormalities. CLINICAL CASE We describe a case of a 73 years old man admitted in our Internal Medicine Unit for acute diarrhoea with vomiting and fever who developed a prolonged gastrointestinal dysmotility syndrome with poor nutritional intake. Although a parenteral support was provided, he developed acute encephalopathy followed by hypotension and lactic acidosis without evidence of renal and hepatic disease or glycemic alterations. Likewise, no cerebral CT and cerebrospinal fluid alterations were found. Conversely, cerebral MRI showed marked and diffuse DP-2 and FLAIR hyperintensity of the mesencephalic tectal plate, of the periaqueductal area, and of the periventricular region of the third ventricle including the median thalamic area. These MRI descriptions were considered pathognomonic of Wernicke encephalopathy. Thus, the immediate use of ev thiamine was followed by a prompt and complete recovery of neurological, hemodinamic and metabolic conditions. CONCLUSIONS Non-alcoholic Wernicke encephalopathy is a rare and dramatic clinical event with high mortality. In this context, brain MRI is the best diagnostic tool providing a typical picture.

    The diagnosis of acute pancreatitis is still mainly based on the clinical signs and symptoms of patients. In a prospective study of 64 patients with acute pancreatitis, computed tomography (CT) findings were correlated with the clinical types of acute pancreatitis. We were able to correctly diagnose 3 acute necrotizing pancreatitis with autopsy and 2 acute hemorrhagic pancreatitis by plain CT about 48 hours after onset. At present, CT about 48 hours after onset seems to be the most accurate method for the early detection of necrotizing, hemorrhagic and edematous forms of acute pancreatitis. (author)

  16. Posterior Reversible Encephalopathy Syndrome (PRES After Acute Pancreatitis

    Tara Murphy

    2015-12-01

    Full Text Available Posterior reversible encephalopathy syndrome (PRES is an unusual condition typified by acute visual impairment caused by sudden, marked parieto-occipital vasogenic edema. Thought to be inflammatory in origin, it has been described in patients undergoing chemotherapy, with autoimmune disease, and in some infections. We report a case of PRES that occurred one week after an episode of acute pancreatitis in an otherwise healthy 40-year-old female. There was progressive visual impairment over a 24-hour period with almost complete visual loss, with characteristic findings on magnetic resonance imaging. After treatment with steroids, the visual loss recovered. Clinicians should retain an index of suspicion of this rare condition in patients with visual impairment after acute pancreatitis.

    2007-01-01

    BACKGROUND:Pancreatic encephalopathy (PE) is a serious complication of severe acute pancreatitis (SAP). In recent years, more and more PE cases have been reported worldwide, and the onset PE in the early stage was regarded as a poor prognosis sign of SAP, but the pathogenesis of PE in SAP still has not been clariifed in the past decade. The purpose of this review is to elucidate the possible pathogenesis of PE in SAP. DATA SOURCES:The English-language literature concern-ing PE in this review came from the Database of MEDLINE (period of 1991-2005), and the keywords of severe acute pancreatitis and pancreatic encephalopathy were used in the searching. RESULTS:Many factors were involved in the pathogenesis of PE in SAP. Pancreatin activation, excessive release of cytokines and oxygen free radicals, microcirculation abnormalities of hemodynamic disturbance, ET-1/NO ratio, hypoxemia, bacterial infection, water and electrolyte imbalance, and vitamin B1 deifciency participated in the development of PE in SAP. CONCLUSIONS:The pathogenesis of PE in SAP has not yet been fully understood. The development of PE in SAP may be a multi-factor process. To ifnd out the possible inducing factor is essential to the clinical management of PE in SAP.

    Increasing occurrence of posterior reversible encephalopathy syndrome has been reported in children with acute lymphoblastic leukemia. However, the etiology of posterior reversible encephalopathy syndrome is not clear. To study the possible pathogenetic mechanisms and treatment of this complication, we reported 11 cases of pediatric acute lymphoblastic leukemia who developed posterior reversible encephalopathy syndrome after induction chemotherapy. After appropriate treatment, the clinical symptoms of posterior reversible encephalopathy syndrome in most cases disappeared even though induction chemotherapy continued. During the 1-year follow-up, no recurrence of posterior reversible encephalopathy syndrome was observed. Although the clinical and imaging features of posterior reversible encephalopathy syndrome may be diverse, posterior reversible encephalopathy syndrome should be recognized as a possible important complication of acute lymphoblastic leukemia when neurologic symptoms appear. In line with previous reports, our study also indicated that posterior reversible encephalopathy syndrome was reversible when diagnosed and treated at an early stage. Thus, the occurrence of posterior reversible encephalopathy syndrome should be considered and investigated to optimize the early induction scheme of acute lymphoblastic leukemia treatment.

    2003-01-01

    Despite of the current achievements of medicine, the mortality of necrotizing pancreatitis (NP) is still too high--up to 35-40% and stands as a serious diagnostic and treatment problem. The results of treatment of 148 patients, admitted in the clinic with diagnosis NP, 95 males and 53 females, are discussed. The ratio between patients with acute oedematic and acute NP is 81.1% to 18.9%. According to the hystopatology findings, the results are as follows: pancreatic necrosis--128 patients, peripancreatic necrosis--42 patients, retropancreatic necrosis--29 patients, phlegmonous cholecystitis--31 patients. For the exact diagnostic estimation of the development and prognosis of NP, we are based on: Clinic symptomatology, biochemical constellations (the prognostic scale of Ranson), ultrasonography, CT, ERCP, ES, laparoscopy (48 pts), and laparoscopic drainage (34 pts) of the abdominal cavity with one or two drains, in order to decrease the intoxication and manage intraperitoneal irrigation with antibiotics and enzymes. The operative intervations consists of a thorough exploration, broad necrectomy combined with lavage and large drainage. COLD (controlled open lesser sac drainage) has been performed at 34 cases. In 31 pts cholecystectomy and choledochotomy with T-tube drainage of d. choledochus (Kehr drainage) was performed. Reoperations have been made at 34 pts (22.9%); in 11 of them--2 operative revisions have been carried out, in 3 cases--three, and in 3 cases--4 operative revisions were performed. The total postoperative death rate was 21.6% (32 patients). The most common postoperative complications were as follows: pulmonary complications at 11 cases, pleural effusions--9 pts, intraabdominal abscesses--6 patients, postnecrotic pseudocysts--9 cases, pancreatic fistulas--6 cases, fistulas of the colon--2 pts, bleeding--4 patients.

    We examined the local hemodynamic response of intestinal loops during acute necrotizing enterocolitis (NEC) in anesthetized rabbits. NEC was induced in ileal loops by transmural injection of a solution containing casein (10 mg/ml) and calcium gluconate (50 mg/ml) acidified to pH 4.0 with propionic or acetic acid. Control loops received casein only (pH 5.0). Mucosal damage was quantified by the blood-to-lumen movement of (51Cr)EDTA, fluid shifts into the lumen, and histology. Mean arterial pressure and loop blood flow were steady over the 3-hr period, loop fluid volume decreased, and there was no evidence of necrosis or epithelial damage. In loops receiving acidified casein and calcium gluconate, there was an immediate dramatic increase in loop blood flow that returned to baseline by 50 min. In addition, loop fluid volume was dramatically increased, necrosis was noted in the form of blunting and loss of villi, and sevenfold increase in (51Cr)EDTA permeability was evident. Administration of CV 1808 (30 mg/kg/hr), a selective adenosine2 agonist, which maintained and elevated loop blood flow throughout the 3 hr protocol, failed to alter the changes in loop fluid volume or prevent necrosis. Histamine levels in loop fluid levels were significantly elevated 20-30 min after NEC induction when compared to saline controls, indicating an early activation of mucosal defenses with this luminal insult. Thus, this model of NEC is characterized by a transient, acute hyperemia, increased intestinal permeability, and histamine release. As mucosal damage was independent of ischemia and could not be prevented by vasodilatory therapy, this model supports the clinical findings that NEC is correlated with luminal factors related to feeding and independent of cardiovascular stress.

  2. CT and MR manifestations of acute methyl alcohol toxic encephalopathy

    Objective: To analyze the CT and MR manifestations of methyl alcohol toxic encephalopathy and to improve the diagnosing value of CT and MRI. Methods: 40 patients with methyl alcohol intoxication were collected in this study, in which CT scan was performed on 40 cases and MRI on 4 cases. All CT and MRI radiological data of brain were retrospectively studied. Results: 13 of 40 cases showed abnormal findings on brain CT and MRI. The most common manifestation (6/13, 46%)was hypodensity in frontal parietal white matter and external capsule-putamen on CT, which showed long or short T1 and long T2 on MR. Hemorrhage in right putamen was found only in 1 patient (1/13,7%). CT showed low density inbilateral external capsule in 4 cases (4/13,31%), in which MR showed long or short T1 and long T2. Low density lesions in subcortical white matter of bilateral frontal and parietal lobes, cingulate gyms and insular lobes were found in 2 patients (2/13,15%). The more severe clinic manifestation, the more obvious brain lesion CT and MRI showed. Conclusion: Brain CT and MR manifestations have great diagnostic value of acute methyl alcohol toxic encephalopathy. MRI was more sensitive and better than CT in finding early brain damage caused by methanol intoxication. (authors)

    Full Text Available Objective To investigate the use of quantitative EEG (qEEG in patients with acute encephalopathies (AEs and EEG background abnormalities. Method Patients were divided into favorable outcome (group A, 43 patients and an unfavorable outcome (group B, 5 patients. EEGLAB software was used for the qEEG analysis. A graphic of the spectral power from all channels was generated for each participant. Statistical comparisons between the groups were performed. Results In group A, spectral analysis revealed spectral peaks (theta and alpha frequency bands in 84% (38/45 of the patients. In group B, a spectral peak in the delta frequency range was detected in one patient. The remainder of the patients in both groups did not present spectral peaks. Statistical analysis showed lower frequencies recorded from the posterior electrodes in group B patients. Conclusion qEEG may be useful in the evaluations of patients with AEs by assisting with the prognostic determination.

  5. A 32 year old male with idiopathic hepatic encephalopathy and necrotic lower extremity

    Schmitz ED

    2010-11-01

    Full Text Available A 32 year old with undiagnosed alpha-1 antitrypsin deficiency had an unusual initial presentation of acute liver failure, septic shock; adult respiratory distress syndrome and what appeared to be a left lower extremity soft tissue infection. Skin biopsy revealed panniculitis. Because of the diagnosis of panniculitis, an alpha-1 antitrypsin level was ordered and demonstrated alpha-1 antitrypsin deficiency with a ZZ phenotype. The patient recovered with antibiotics and supportive therapy. This case illustrates that alpha-1 antitrypsin deficiency can present other that the more usual adult presentation of progressive emphysema. Unexplained panniculitis should prompt investigation of alpha-1 antitrypsin deficiency in the adult patient.

    Acute encephalopathy with febrile convulsive status epilepticus (AEFCSE) is the most common type of acute encephalopathy in childhood in Japan, which develops with prolonged febrile convulsion, followed by mild unconsciousness. It is generally sporadic and nonrecurrent. In this report, a 1-year-old girl showed signs of AEFCSE triggered by respiratory syncytial virus infection. Two years later, she presented with AEFCSE triggered by influenza virus infection, resulting in severe neurologic sequelae. The patient had a thermolabile genotype of carnitine palmitoyltransferase II (CPT II) variations consisting of three single nucleotide polymorphisms in exons 4 [1055T > G/F352C and 1102G > A/V368I] and 5 [1939A > G/M647V]. The polymorphism has been identified as a genetic predisposition for acute encephalopathy. This report presents the first case of recurrent encephalopathy with CPT II variations that may partially associate with pathogenesis of recurrent AEFCSE. PMID:23450341

    Acute renal injury caused by acute necrotizing pancreatitis (ANP) is a common complication that is associated with a high rate of mortality. Paeoniflorin is the active ingredient of paeonia radix and exhibits a number of pharmacological effects, such as anti‑inflammatory, anticancer, analgesic and immunomodulatory effects. The present study detected the potential treatment effects of paeoniflorin on acute renal injury induced by ANP in a rat model. The optimal dose of paeoniflorin for preventing acute renal injury induced by ANP was determined. Then, the possible protective mechanism of paeoniflorin was investigated. The serum levels of tumor necrosis factor (TNF)‑α, interleukin (IL)‑1β and IL‑6 were measured with enzyme‑linked immunosorbent assay kits. Renal inflammation and apoptosis were measured by immunohistochemistry and terminal deoxynucleotidyl transferase‑mediated dUTP nick end labeling assay. The expression of nitric oxide in kidney tissues was also evaluated. The p38 mitogen‑activated protein kinases (MAPKs) were measured by western blotting. The results shown that paeoniflorin may ameliorate acute renal injury following ANP in rats by inhibiting inflammatory responses and renal cell apoptosis. These effects may be associated with the p38MAPK and nuclear factor‑κB signal pathway. PMID:27279569

  8. Biomarkers of acute kidney injury in neonatal encephalopathy.

    Sweetman, D U

    2013-03-01

    Acute kidney injury (AKI) is a common complication of neonatal encephalopathy (NE). The accurate diagnosis of neonatal AKI, irrespective of the cause, relies on suboptimal methods such as identification of rising serum creatinine, decreased urinary output and glomerular filtration rate. Studies of AKI biomarkers in adults and children have shown that biomarkers can improve the early diagnosis of AKI. Hypoxia-ischaemia is the proposed aetiological basis of AKI in both NE and cardiopulmonary bypass (CPB). However, there is a paucity of studies examining the role of AKI biomarkers specifically in NE. Urinary cystatin C (CysC), neutrophil gelatinase-associated lipocalin (NGAL), interleukin-18, kidney injury molecule-1, liver-type fatty acid-binding protein, serum CysC and serum NGAL all show good ability to predict early AKI in a heterogeneous critically ill neonatal population including infants post-CPB. Moreover, serum and urinary NGAL and urinary CysC are early predictors of AKI secondary to NE. These findings are promising and open up the possibility of biomarkers playing a significant role in the early diagnosis and treatment of NE-related AKI. There is an urgent need to explore the role of AKI biomarkers in infants with NE as establishing the diagnosis of AKI earlier may allow more timely intervention with potential for improving long-term outcome.

  11. Clinical characteristics of acute encephalopathies associated with influenza H1N1-2009 in children

    We report 12 cases of acute encephalopathy associated with influenza H1N1-2009 treated according to Japanese guideline (2009). In all 12 cases, electroencephalogram presented diffuse or localized high-amplitude slow waves. Brain CT and MRI showed abnormalities in 4 and 6 cases, respectively. We used hypothermia therapy for 5 patients. One patient showed impairment in short term memory, while the rest of the patients showed no sequelae. These 12 cases presented here suggest the early recognition and therapy according to the newly proposed guideline may reduce severe sequelae and mortality by acute encephalopathy associated with influenza H1N1-2009.

    We describe an 18-year-old man with acute leukemia who presented with posterior reversible encephalopathy syndrome (PRES) shortly after developing acute pancreatitis. On day 15 after the third consolidation course with high-dose cytarabine, treatment with broad-spectrum antibiotics was initiated for febrile neutropenia. On day 16, he developed septic shock, and subsequently, acute respiratory distress syndrome (ARDS). After adding vancomycin, micafungin and high-dose methylprednisolone (mPSL) to his treatment regimen, these manifestations subsided. On day 22, he received hemodialysis for drug-induced acute renal failure. On day 24, he developed acute pancreatitis possibly due to mPSL; the following day he had generalized seizures, and was intubated. Cerebrospinal fluid findings were normal. Brain MRI revealed hyperintense signals on FLAIR images and increased apparent diffusion coefficient values in the sub-cortical and deep white matter areas of the bilateral temporal and occipital lobes, indicative of vasogenic edema. Thus, we diagnosed PRES. Blood pressure, seizures and volume status were controlled, with MRI findings showing improvement by day 42. He was extubated on day 32 and discharged on day 49 without complications. Although little is known about PRES following acute pancreatitis, clinicians should be aware that this condition may develop. PMID:24881921

  15. Ligustrazine alleviates acute lung injury in a rat model of acute necrotizing pancreatitis

    Jian-Xin Zhang; Sheng-Chun Dang

    2006-01-01

    BACKGROUND:Acute necrotizing pancreatitis leads to a systemic inlfammatory response characterized by widespread leukocyte activation and, as a consequence, distant lung injury. The aim of this study was to evaluate the effect of ligustrazine, extracted from Ligusticum wallichii a traditional Chinese medicine, on lung injury in a rat model of acute necrotizing pancreatitis (ANP). METHODS:A total of 192 rats were randomly divided into three groups: control (C group); ANP without treatment (P group); and ANP treated with ligustrazine (T group). Each group was further divided into 0.5, 2, 6 and 12 hours subgroups. All rats were anesthetized with an intraperitoneal injection of sodium pentobarbital. Sodium taurocholate was infused through the pancreatic membrane to induce ANP. For the T group, sodium taurocholate was infused as above, then 0.6%ligustrazine was administered via the femoral vein. The effects of ligustrazine on the severity of lung injury were assessed by lung wet/dry weight ratio, myeloperoxidase (MPO) activity and histopathological changes. Pulmonary blood lfow was determined by the radioactive microsphere technique (RMT). RESULTS:The blood lfow in the P group was signiifcantly lower than that of the C group, while the blood lfow in the T group was signiifcantly higher than that of the P group but showed no signiifcant difference from the C group. Compared with C group, the lung wet/dry ratios in both the P and T groups were signiifcantly increased, but there was no signiifcant difference between them. The MPO activity in the P group was greatly increased over that of the C group. In the T group, although the MPO activity was also higher than in the C group, it much less increased than in the P group. Moreover, the difference between P and T groups was signiifcant after 0.5 to 12 hours. After induction of the ANP model, the pancreas showed mild edema and congestion;the longer the time, the more severe this became. The pulmonary pathological changes were

  19. Antiproteases in the Treatment of Acute Necrotizing Pancreatitis: Continuous Regional Arterial Infusion

    Kazunori Takeda

    2007-07-01

    Full Text Available Acute necrotizing pancreatitis is still a fatal disease. Pancreatic necrosis might be, in part, a result of infarction due to ischemia with vasospasm and an increase in intravascular coagulability. Synthetic antiproteases have a broad inhibitory action on pancreatic enzymes, the coagulation system, the complement system and the production of proinflammatory cytokines. Therefore, antiproteases have been expected to prevent necrotic changes in the pancreas and to reduce the mortality rate. However, the clinical efficacy of antiproteases is still a matter of controversy. Unfortunately, an antiprotease cannot easily reach the pancreas when administered intravenously because of its pharmacokinetic characteristics and impaired microcirculation. Administration through a catheter placed in one of the arteries which supplies the inflamed area of the pancreas, dramatically increases the concentration of the antiprotease in the pancreas. Clinical studies of continuous regional arterial infusion of a protease inhibitor have been conducted in Japan and have demonstrated the possible therapeutic efficacy of the new treatment in severe acute pancreatitis.

  20. Acinar cell ultrastructure after taurine treatment in rat acute necrotizing pancreatitis

    To evaluate the organelle-based changes in acinar cells in experimental acute necrotizing pancreatitis (ANP) after taurine treatment and the association of electron microscopic findings with histopathalogical changes and oxidative stress markers. The study was performed in February 2005at Gulhane School of Medicine and Hacettepe University, Turkey. Forty-five rats were divided into 3 groups. Acute necrotizing pancreatitis was induced in groups II and III. Groups I and II were treated with saline and Group III with taurine 1000mg/kg/day, i.p, for 48 hours. Histopathological and ultrastructural examinations were determined using one-way analysis of variance and Kruskal-Wallis tests. Histopathologic findings improved significantly after taurine treatment. Degree of injury in rough and smooth endoplasmic reticulums, Golgi apparatus, mitochondria and nucleus of acinar cells also decreased with taurine in correlation with biochemical and histological results. Taurine improves acinar cell organelle structure, and ultrastructural recovery in ANP reflects histological improvement. (author)

    Mahendra K Patel

    2012-01-01

    Full Text Available A nine year old female patient presented with complaints of severe colicky abdominal pain, vomiting, and tingling with numbness for 3 days. Acute necrotizing pancreatitis associated with tetany due to anti-retroviral therapy was diagnosed. Stavudine was the probable causal agent. Unfortunately, the patient died due to severity of the reaction. High index of suspicion and early withdrawal of the offending drug may prevent further harm in such cases.

    Full Text Available AIM: To assess the outcome of patients with acute necrotizing pancreatitis treated by percutaneous drainage with special focus on the influence of drainage size and number.METHODS: We performed a retrospective analysis of 80 patients with acute pancreatitis requiring percutaneous drainage therapy for infected necroses. Endpoints were mortality and length of hospital stay. The influence of drainage characteristics such as the median drainage size, the largest drainage size per patient and the total drainage plane per patient on patient outcome was evaluated.RESULTS: Total hospital survival was 66%. Thirty-four patients out of all 80 patients (43% survived acute necrotizing pancreatitis with percutaneous drainage therapy only. Eighteen patients out of all 80 patients needed additional percutaneous necrosectomy (23%. Ten out of these patients required surgical necrosectomy in addition, 6 patients received open necrosectomy without prior percutaneous necrosectomy. Elective surgery was performed in 3 patients receiving cholecystectomy and one patient receiving resection of the parathyroid gland. The number of drainages ranged from one to fourteen per patient. The drainage diameter ranged from 8 French catheters to 24 French catheters. The median drainage size as well as the largest drainage size used per patient and the total drainage area used per patient did not show statistically significant influence on mortality.CONCLUSION: Percutaneous drainage therapy is an effective tool for treatment of necrotizing pancreatitis. Large bore drainages did not prove to be more effective in controlling the septic focus.

Eighteen patients out of all 80 patients needed additional percutaneous necrosectomy (23%). Ten out of these patients required surgical necrosectomy in addition, 6 patients received open necrosectomy without prior percutaneous necrosectomy. Elective surgery was performed in 3 patients receiving cholecystectomy and one patient receiving resection of the parathyroid gland. The number of drainages ranged from one to fourteen per patient. The drainage diameter ranged from 8 French catheters to 24 French catheters. The median drainage size as well as the largest drainage size used per patient and the total drainage area used per patient did not show statistically significant influence on mortality. CONCLUSION: Percutaneous drainage therapy is an effective tool for treatment of necrotizing pancreatitis. Large bore drainages did not prove to be more effective in controlling the septic focus.

    Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is the most common subtype of infectious pediatric encephalopathy in Japan. The exact pathogenesis of and the best therapeutic strategy for AESD are uncertain. We firstly performed a brain biopsy in a 2-year-old boy with AESD associated with RS viral infection, which revealed activated ameoboid microglia accumulation around degenerated neuron, and astrogliosis in the affected cortex. Glutamate released from activated microglia may play an important role in the pathogenesis of AESD, which is compatible with the previous report of magnetic resonance spectroscopy showing elevated glutamate.

  6. Continuous Regional Arterial Infusion Therapy for Acute Necrotizing Pancreatitis Due to Mycoplasma pneumoniae Infection in a Child

    A case of acute necrotizing pancreatitis due to Mycoplasma pneumoniae infection was treated in an 8-year-old girl. She experienced acute pancreatitis during treatment for M. pneumoniae. Contrast-enhanced computed tomographic scan revealed necrotizing pancreatitis. The computed tomographic severity index was 8 points (grade E). A protease inhibitor, ulinastatin, was provided via intravenous infusion but was ineffective. Continuous regional arterial infusion therapy was provided with gabexate mesilate (FOY-007, a protease inhibitor) and meropenem trihydrate, and the pancreatitis improved. This case suggests that infusion therapy is safe and useful in treating necrotizing pancreatitis in children.

  7. Posterior reversible encephalopathy syndrome and acute post-streptococcal glomerulonephritis mimicking breakthrough seizures

    2015-05-01

    Full Text Available We report the case of a 14-year-old boy with a past history of primary generalized seizures, who had been seizure-free for 2 years on sodium valproate and presented with generalized tonic clonic seizures suggestive of breakthrough seizures. Examination revealed hypertension, impetiginous lesions of the lower limbs, microscopic hematuria, elevated antistreptolysin O titre and low complement levels consistent with acute post-streptococcal glomerulonephritis. Cranial magnetic resonance imaging (MRI demonstrated changes consistent with posterior reversible encephalopathy syndrome. Hypertension was controlled with intravenous nitroglycerin followed by oral captopril and amlodipine. Brain MRI changes returned normal within 2 weeks. The nephritis went in to remission within 2 months and after 8 months the patient has been seizure free again. Posterior reversible encephalopathy syndrome appeared to have neither short nor intermediate effect on seizure control in this patient. The relationship between posterior reversible encephalopathy syndrome and seizures is reviewed.

  8. Ischemic Acute Necrotizing Pancreatitis in a Marathon Runner. Comment

    2009-03-01

    Full Text Available Dear Sir we read the contribution by Mast et al. with great interest [1]. They report on this unfortunate gentleman who developed acute pancreatitis after running marathon and taking a sauna. Although this combination of physical activities is not so uncommon in the Nordic countries, particularly during winter time, no such experience or reports exist on pancreatitis. Morbidity and mortality of sauna bathing is rather low [2], despite the fact that there is a readiness to combine sauna with alcohol intake. The more this case report appears worth publishing, even though we should have appreciated some more data on the level of hemoconcentration in this runner and sauna bather Furthermore, as it is routine in our pancreas clinic these days, we would have searched also for one of the known genetic factors contributing to the development of pancreatitis such as mutations in PRSS1, SPINK1, CFTR and CTRC genes [3]. Even more though in a patient who does not have one of the known or obvious causes such as alcohol, gallstones or hyperlipidemia. Further, despite his obvious physical condition, the presence of atherosclerotic microangiopathy would be worth knowing in a 57-year-old man, since most of the ischemic etiologies are thought to be associated with atherosclerotic disease [4].

    Acute encephalitis/encephalopathy is a severe neurological syndrome that is occasionally associated with viral infection. Comprehensive virus detection assays are desirable because viral pathogens have not been identified in many cases. We evaluated the utility of next-generation sequencing (NGS) for detecting viruses in clinical samples of encephalitis/encephalopathy patients. We first determined the sensitivity and quantitative performance of NGS by comparing the NGS-determined number of sequences of human herpesvirus-6 (HHV-6) in clinical serum samples with the HHV-6 load measured using real-time PCR. HHV-6 was measured as it occasionally causes neurologic disorders in children. The sensitivity of NGS for detection of HHV-6 sequences was equivalent to that of real-time PCR, and the number of HHV-6 reads was significantly correlated with HHV-6 load. Next, we investigated the ability of NGS to detect viral sequences in 18 pediatric patients with acute encephalitis/encephalopathy of unknown etiology. A large number of Coxsackievirus A9 and mumps viral sequences were detected in the cerebrospinal fluid of 2 and 1 patients, respectively. In addition, Torque teno virus and Pepper mild mottle viral sequences were detected in the sera of one patient each. These data indicate that NGS is useful for detection of causative viruses in patients with pediatric encephalitis/encephalopathy. PMID:27625312

    Eleven piglets with haemorrhagic necrotizing pancreatitis and nine piglets with oedematous pancreatitis were imaged using a multi-breath-hold TurboFLASH (TR 6.5 ms, TE 3 ms, TI 300 ms, flip angle 8 , three slices) pre-excited T1-weighted sequence with an IV bolus injection of gadopentetate dimeglumine (Gd-DTPA, 0.3 mmol/kg) as a contrast agent to show dynamic contrast enhancement of the pancreas by MRI. All piglets were imaged according to the same protocol before inducing the disease. Following the IV Gd-DTPA bolus, time-enhancement curve of the pancreas during haemorrhagic necrotizing pancreatitis was significantly lower than during oedematous pancreatitis. The enhancement curves for the healthy piglets and piglets with oedematous pancreatitis did not differ significantly. Each piglet served as its own control. Because the results of this initial study are similar to those obtained with contrast-enhanced CT, we conclude that our results may encourage further clinical trials, and contrast-enhanced dynamic MRI may be an alternative to the established method of CT for diagnosing acute haemorrhagic necrotizing pancreatitis.

    2013-05-01

    We describe a male infant with carnitine palmitoyltransferase 2 (CPT2) deficiency who presented with acute encephalopathy related to human herpesvirus-6 (HHV-6) infection. He was hospitalized for pylexia and status epilepticus, diagnosed with acute encephalopathy, and treated with intensive supportive care including mechanical ventilation, support for hypothermia, and control of the intracranial pressure, that caused severe neurological sequelae. HHV-6 was detected in his cerebrospinal fluid, indicating HHV-6 related encephalopathy. In the acute phase, acylcarnitine analysis of blood suggested a defect of long chain fatty acid β-oxidation, and CPT2 deficiency was genetically confirmed. In addition, other gene alterations that have been previously reported as "thermolabile variants" were found. Some patients with the infantile form of CPT2 deficiency present with acute encephalopathy, but others do not develop encephalopathy. The correlation between phenotype and genotype has not been clarified. Our case may contribute to the elucidation of the genetic factor involved in acute encephalopathy in CPT2 deficiency.

  15. Acute encephalitis and encephalopathy associated with human parvovirus B19 infection in children.

    Watanabe, Toru; Kawashima, Hideshi

    2015-11-01

    Reports of neurologic manifestations of human parvovirus B19 (B19) infection have been on the rise. Acute encephalitis and encephalopathy is the most common, accounting for 38.8% of total B19-associated neurological manifestations. To date, 34 children with B19 encephalitis and encephalopathy have been reported, which includes 21 encephalitis and 13 encephalopathy cases. Ten (29%) were immunocompromised and 17 (39%) had underlying diseases. Fever at the onset of disease and rash presented in 44.1% and 20.6% of patients, respectively. Neurological manifestations include alteration of consciousness occurred in all patients, seizures in 15 (44.1%) patients, and focal neurologic signs in 12 (35.3%) patients. Anemia and pleocytosis in cerebrospinal fluid (CSF) occurred in 56.3% and 48.1% of patients, respectively. Serum Anti-B19 IgM (82.6%) and CSF B19 DNA (90%) were positive in the majority of cases. Some patients were treated with intravenous immunoglobulins and/or steroids, although an accurate evaluation of the efficacy of these treatment modalities cannot be determined. Nineteen (57.6%) patients recovered completely, 11 (33.3%) patients had some neurological sequelae and 3 (8.8%) patients died. Although the precise pathogenesis underlying the development of B19 encephalitis and encephalopathy is unclear, direct B19 infection or NS1protein of B19 toxicity in the brain, and immune-mediated brain injuries have been proposed.

Aunque su mecanismo no es del todo conocido, el compromiso isquémico parece ser el factor fisiopatológico fundamental. Cuando la esofagitis necrotizante aguda es un hallazgo en el estudio endoscópico de hemorragia digestiva alta, sin desestabilización hemodinámica, el pronóstico es bueno. Presentamos un caso en el que el diagnóstico de esófago negro fue un mero hallazgo endoscópico, secundario a una situación de inestabilidad hemodinámica subyacente, con resultado fatal.Acute necrotizing esophagitis or black esophagus is a rare affection, described in the medical literature since 1990. Although its mechanism is not fully understood, ischemic compromise appears to be the fundamental physiopathological factor. When acute necrotizing esophagitis is found in the endoscopic study of an upper digestive haemorrhage, the prognosis is good. We present a case in which diagnosis of black esophagus was an endoscopic finding, secondary to a situation of underlying hemodynamic instability, with a fatal outcome.

    2000-01-01

    Objective To evaluate the changes of pancreatic acinar cell functions in the rats with acute necrotizing pancreatitis (ANP). Methods Seventy SD rats were randomized into two groups: experimental group (n=35) and control group (n=35). To prepare the experimental model, the retrograde injection of 5% sodium taurocholate into the pancreatic duct was used for inducing ANP. Radioactive tracing by L- 3H-phenylalanine and autoradiography were performed for scoring the differences of changes of amino acid uptake, enzyme-protein synthesis and output from acinar cells in rats between both groups. Results No changes were observed in amino acid uptake and enzyme-protein synthesis in rats with dotted and haemorrhagic necrotizing foci as compared with control group. However, accumulated zymogen granules in the interstitial of acinar cells were seen in the experimental group. Conclusion It indicates that in experimental ANP rats, the functions of acinar cells in both amino acid uptake and protein synthesis were essentially normal, but the pathway of enzyme output was affected into ectopic secretion through the bottom or lateral cellular membrane of pancreatic acinar cell.

  19. Acute toxic encephalopathies: CT and MR imaging features

    An endless variety of toxins can cause degenerative brain lesions both by chronic use of small amounts and by acute exposures from industrial accidents or suicide attempts. The more commonly occurring toxins encountered clinically include carbon monoxide, cyanide, methanol, and ethylene glycol. CT and MR imaging are of great importance in the assessment of the comatose patient. Some of these toxins have a propensity for selective bilateral and symmetric involvement of the basal ganglia as well as the white matter. CT and MR can demonstrate the extent and distribution of the morphologic brain changes

  20. Non-alcoholic acute Wernicke's encephalopathy: Role of MRI in non typical cases

    Aim: Acute Wernicke's encephalopathy (WE) is a severe neurological disorder caused by thiamine deficiency, most commonly found in chronic alcoholics. It is not so easy to suspect acute WE when the clinical picture does not include all the typical symptoms and alcohol abuse is not reported. Three rare cases of Wernicke's encephalopathy (WE) in non-alcoholic patients are reported. Cases presentation: Two patients developed the disease following prolonged intravenous feeding, the third was carrying a gastric lymphoma. None of them presented with the classic clinical triad of WE (ophtalmoplegia/nystagmus, ataxia and consciousness disturbance), showing just one or two of the typical symptoms. Brain Magnetic Resonance Imaging (MRI) represented the key tool to suspect and define WE diagnosis, showing a picture characterized by bilaterally altered signal of the thalamic pulvinar, mesencephalic cup, mammillary bodies, periaqueductal grey matter and floor of fourth ventricle. All patients dramatically improved within 48 h after administration of thiamine. Conclusion: We emphasize that WE should be suspected in all patients showing typical MRI features presenting with at least one of the clinical triad of WE.

    2015-11-15

    Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is the most common subtype of infectious pediatric encephalopathy in Japan. It is sometimes difficult to make an early diagnosis of AESD; excitotoxicity is postulated to be the pathogenesis based on elevated glutamine (Gln) and glutamate (Glu) complex (Glx = Glu + Gln) observed on MR spectroscopy. It is uncertain whether Gln or Glu contributes to the elevated Glx, or whether MR spectroscopy is useful for an early diagnosis. Five Japanese patients with AESD (three boys and two girls, 1 year of age) were enrolled in this study. MR spectroscopy was acquired from the frontal white matter (repetition time (TR) of 5000 ms, echo time (TE) of 30 ms) with a 1.5- or 3.0-T scanner. MR spectroscopy was performed four times for two patients, three times for one patient, and two times for two patients. Quantification of Glu and Gln was performed using LCModel. Glu was elevated in three of four studies on days 1-4 and became normal or low afterward. Gln was normal in three studies on days 1-2, elevated in all seven studies on days 4-12, and became normal or low afterward. These findings suggest that MR spectroscopy may be useful for an early diagnosis. Acute Glu elevation changes to subacute Gln elevation, suggesting that a disrupted Glu-Gln cycle may play an important role. (orig.)

    The expression of microRNA-19b (miR-19b) in acute necrotizing pancreatitis (ANP) and its functional role in acinar cell necrosis of SD rats were investigated. Twelve SD rats were divided into two groups randomly, including control group and ANP group. The rat ANP models were established by intraperitoneal injection of L-arginine (2400 mg/kg body weight), and equal volume of 0.9% NaCl was injected in the control group. MiRNA chip assay was performed to examine the expression of miRNAs in the pancreas in two different groups. Besides, to further explore the role of miR-19b in ANP in vitro, taurolithocholic acid 3-sulfate disodium salt (TLC-S) (200 μmol/L) was administrated to treat the rat pancreatic acinar cell line, AR42J, for establishing the ANP cells model. The quantitative real-time PCR (qRT-PCR) was adopted to measure the miR-19b expression. Moreover, the mimic miRNA, miRNA antisense oligonucleotide (AMO) and control vector were used to transfect AR42J cells, the expression of miR-19b was confirmed by qRT-PCR and the necrotizing rate of AR42J cells was detected with AO/EB method. The expression of miR-19b was significantly higher in ANP group than in control group as displayed by the miRNA chip assay. Furthermore, after inducing necrosis of AR42J cells in vitro, the expression of miR-19b was significantly increased by 2.51±0.14 times in comparison with the control group. As revealed by qRT-PCR assay, the expression of miR-19b was 5.94±0.95 times higher in the mimic miRNA group than in the control vector group, companied with an obviously increased acinar cell necrotizing rate (50.3%±1.5% vs. 39.6%±2.3%, P0.05). The expression of miR-19b was significantly induced in ANP. In addition, up-regulation of miR-19b could promote the necrosis of pancreatic acinar cells and miR-19b deficiency could decrease the rate of pancreatic acinar cell necrosis. PMID:27072966

    2014-10-01

    Full Text Available Delayed encephalopathy after acute carbon monoxide poisoning (DEACMP is a syndrome constituted by acute dementia, psychiatric symptoms, pyramidal and extrapyramidal symptoms, which can be developed after the original clinical symptoms of carbon monoxide poisoning recovered. Lots of studies have been done to explain the mechanisms of DEACMP, and more and more researches have demonstrated that the immunological mechanism may be involved in or play an important role on the pathogenesis of the process. This article will review the researches of immunological mechanism of DEACMP in recent years and give some prompts to clinical study in the future. doi: 10.3969/j.issn.1672-6731.2014.10.006

  5. Posterior reversible encephalopathy syndrome: an acute manifestation of systemic lupus erythematous.

    Chan, Dexter Yak Seng; Ong, Yin Sheng

    2013-09-01

    Stroke mimickers are common, and they represent a diagnostic dilemma for clinicians. Many, like posterior reversible encephalopathy syndrome (PRES), are easily reversible. The manifestation of PRES is characterised by headaches, convulsions, altered mental functioning and blindness. In most cases, computed tomography of the brain will show hypodense lesions in the parieto-occpitial lobe, which only further confounds the physician. Although this syndrome is uncommon, prompt and accurate recognition allows early treatment, which has been shown to produce favourable outcomes. Herein, we report the case of a 54-year-old woman, who presented with PRES, as an acute manifestation of systemic lupus erythematous (SLE) and lupus nephritis. The patient was initially thought to be experiencing an ischaemic stroke, but the diagnosis was later changed. On management of her underlying condition, her symptoms resolved. PRES should be recognised as an acute emergency manifestation of SLE. It should not be mistaken for an ischaemic stroke as inappropriate treatment could have adverse outcomes. PMID:24068069

    2011-02-01

    Full Text Available Abstract Introduction Infections are the most frequent and severe complications of acute necrotizing pancreatitis with a mortality rate of up to 80 percent. Although experimental and clinical studies suggest that the microbiologic source of pancreatic infection could be enteric, information in this regard is controversial. Case presentation We describe a Citrobacter freundii isolation by endoscopy ultrasound fine needle aspiration in a 80-year-old Caucasian man with pancreatic pseudocyst after acute necrotizing pancreatitis. Conclusion Our case report confirms that this organism can be recovered in patients with a pancreatic pseudocyst. On-site cytology feedback was crucial to the successful outcome of this case as immediate interpretation of the fine needle aspiration sample directed the appropriate cultures and, ultimately, the curative therapy. To the best of our knowledge, this is the first reported case of isolated pancreatic C. freundii diagnosed by endoscopy ultrasound fine needle aspiration.

    Abstract Peritoneal lavage and dialysis is an approach to treat necrotizing acute pancreatitis as it removes dialyzable toxins and reduces severe metabolic disturbances. Successful catheter implantation is important for delivering adequate peritoneal lavage and dialysis. The aim of the present study was to describe a new modified percutaneous technique for the placement of peritoneal dialysis catheters and assess the effectiveness and safety of peritoneal lavage and dialysis used for treatment of necrotizing acute pancreatitis. We conducted a retrospective data review of 35 patients of necrotizing acute pancreatitis from January 2010 to December 2014 in Jilin City Central Hospital and The First Affiliated Hospital of ZheJiang University. In total, 18 patients underwent peritoneal lavage and dialysis after inserting catheters by our new technique (group A), whereas 17 patients underwent ultrasound-guided percutaneous catheter drainage (group B). By analyzing the patients’ data, the drainage days and mean number of hours between the debut of the symptoms and the hospital admission were lower in group A (P < 0.05, P < 0.05, respectively). The complication rate of 5.6 and 17.6%, respectively (P = 0.261), and a mortality rate of 16.7 and 5.9% for each group, respectively (P = 0.316). Likewise, hospitalization time was similar for the group A: 31 ± 25.3 days compared with 42.8 ± 29.4 days in the group B (P = 0.211). Peritoneal lavage and dialysis can be used in necrotizing acute pancreatitis, and our new modified percutaneous technique offers the same complication and mortality rate as ultrasound-guided drainage but with a shorter drainage days.

    Abstract Introduction Infections are the most frequent and severe complications of acute necrotizing pancreatitis with a mortality rate of up to 80 percent. Although experimental and clinical studies suggest that the microbiologic source of pancreatic infection could be enteric, information in this regard is controversial. Case presentation We describe a Citrobacter freundii isolation by endoscopy ultrasound fine needle aspiration in a 80-year-old Caucasian man with pancreatic pseudocyst afte...

    2011-01-01

    Full Text Available Parieto-occipital region is the most commonly involved site in posterior reversible encephalopathy syndrome (PRES. Cerebellar involvement has been reported with the predominant involvement of posterior cerebral regions, but isolated cerebellar involvement in PRES has been reported only once in English literature. We report here a 7-year-old boy with acute lymphoblastic leukemia who had PRES with isolated cerebellar involvement during induction chemotherapy. He presented with sudden onset headache, vomiting and hypertension followed by seizures, unconsciousness, and involuntary movements. Computed tomography scan revealed bilateral cerebellar hypodensities. He improved within few hours and reversibility of the lesions was documented on magnetic resonance imaging after 2 weeks. Awareness of atypical patterns in distribution of imaging abnormalities is important to recognize PRES more accurately and to avoid unnecessary diagnostic procedures and treatment.

    Full Text Available Introduction: The posterior reversible encephalopathy syndrome (PRES is a neurological entity characterized by magnetic resonance imaging (MRI evidence of bilateral subcortical edema in the occipital regions of the brain. Case report: We report the case of a female patient with AIDS, pulmonary aspergillosis, CMV infection, and acute renal failure due to Clostridium difficile diarrhea. Her clinical course was complicated by seizures and hypertension. MRI findings were consistent with PRES. The patient was treated with anticonvulsants and antihypertensive agents with clinical improvement. Discussion and conclusions: Few cases of PRES in HIV-infected patients have been described, and it is not clear whether HIV infection is a predisposing factor for this syndrome. The article reviews the literature on PRES in HIV and discusses the role of HIV-associated endothelial damage in the pathogenesis of this syndrome.

  12. Brain perfusion single photon emission computed tomography in children after acute encephalopathy

    We studied single photon emission computed tomography (SPECT) of 15 children with acute encephalopathy after more than 1 year from the onset, using technetium-99 m-L, L-ethyl cystinate dimer (99mTc-ECD) and a three-dementional stereotaxic region of interest template. Regional cerebral blood flow was evaluated and divided in three groups according to the severity of disability: absent or mild, moderate, and severe. There was no abnormality on SPECT in the patients without disability or with mild disability. Diffuse hypoperfusion was shown in the groups with moderate and severe disability. The patients with severe disability showed hypoperfusion in the pericallosal, frontal and central areas which was more pronounced than in the patients with moderate disability. (author)

    Full Text Available Infection with Epstein–Barr virus (EBV is very common and usually occurs in childhood or early adulthood. Encephalitis/encephalopathy is an uncommon but serious neurological complication of EBV. A case of EBV-associated encephalitis/encephalopathy with involvement of reversible widespread cortical and splenial lesions is presented herein. An 8-year-old Chinese girl who presented with fever and headache, followed by seizures and drowsiness, was admitted to the hospital. Magnetic resonance imaging revealed high signal intensities on diffusion-weighted imaging in widespread cortical and splenial lesions. The clinical and laboratory examination results together with the unusual radiology findings suggested acute encephalitis/encephalopathy due to primary EBV infection. After methylprednisolone pulse therapy together with ganciclovir, the patient made a full recovery without any brain lesions. The hallmark clinical–radiological features of this patient included severe encephalitis/encephalopathy at onset, the prompt and complete recovery, and rapidly reversible widespread involvement of the cortex and splenium. Patients with EBV encephalitis/encephalopathy who have multiple lesions, even with the widespread involvement of cortex and splenium of the corpus callosum, may have a favorable outcome with complete disappearance of all brain lesions.

  14. Colonic involvement in non-necrotizing acute pancreatitis: correlation of CT findings with the clinical course of affected patients

    The purpose of this study was to describe CT findings of colonic involvement in acute non-necrotizing pancreatitis and to analyze the correlation between colonic wall thickening at CT and the clinical course of these patients. The CT examinations of 19 consecutive patients with acute non-necrotizing pancreatitis who were not treated with antibiotics initially were analyzed retrospectively. The severity of acute pancreatitis was categorized according to the CT severity index (CTSI) and the presence of colonic wall thickening at the initial CT was compared with the clinical course of all patients. Seven of 11 patients with a CTSI of 4 showed a colonic wall thickening, whereas the remaining patients with a CTSI of 4 (n=4), CTSI of 3 (n=5), and CTSI of 2 (n=3) showed no colonic abnormalities at CT. Patients with colonic wall thickening presented more often with fever, showed higher levels of infectious parameters, needed more often antibiotic therapy, and had more requests for additional CT examinations and CT-guided fluid aspirations as well as a longer duration of hospital stay as compared with patients without colonic wall involvement, even if the latter presented with the same CTSI initially. It is well known that translocation of the colonic flora may significantly influence the clinical course of patients with acute pancreatitis, and our results indicate that patients with acute pancreatitis who present with colonic wall thickening at CT have an increased risk for a complicated clinical course regarding systemic infection.

  16. Magnetic resonance (MR) imaging in delayed encephalopathy of acute carbon monoxide poisoning - comparison with CT -

    Eleven magnetic resonance (MR) and computed tomographic (CT) imaging were performed in nine patients with mild to moderate degree of delayed neuropsychiatric symptoms following acute carbon monoxide (CO) poisoning, to evaluate the capability of MR in demonstrating any additional finding to CT. The MR images were obtained using 0.15 Tesla resistive system with various combination of three pulse sequences, including partial saturation recovery, T2-weighted spin echo and inversion recovery. Bilateral white matter abnormalities suggesting demyelination were demonstrated in 4 patients with MR and in only 2 patients with CT. The contrast discrimination between normal and abnormal white matter proved to be better with T2-weighted spin echo and inversion recovery than with partial saturation recovery and CT. But necrosis of the globus pallidus (1 patient) and diffuse atrophy (3 patients) were equally demonstrated on both MR and CT. It is suggested that MR be used as a initial imaging method in the evaluation of the delayed encephalopathy following acute CO poisoning, especially for the detection of the possible white matter lesions. Acute carbon monoxide (CO) poisoning produces hypoxia by displacing oxygen from hemoglobin and preventing its release from hemoglobin in tissues, often resulting in fetal event. Victims who survive acute CO poisoning may have various delayed symptoms and signs. Occasionally, an apparent recovery is followed within two days to three weeks by a sudden neurological deterioration. The degree of neuropsychiatric symptoms depends upon the extent and severity of the pathologic changes in the brain. The pathologic effects of CO poisoning are present in almost all organs of patients. However, the most important changes occur in the brain, which consist of necrosis of the globus pallidus and reticular zone of the substantia nigra, and the degeneration of the cerebral white matter. The diagnostic superiority of magnetic resonance (MR) over CT has already

    2016-01-01

    Necrotizing fasciitis is a rare bacterial skin condition which forms a major diagnostic challenge and is associated with poor prognosis unless promptly treated. Initial clinical presentation is often misleading with characteristic features developing only late in the course of the disease. In this review, we discuss the applicability and usefulness of laboratory risk indicator for necrotizing fasciitis score in facilitating rapid diagnosis of necrotizing fasciitis in emergency department by differentiating it from other skin in-fections like cellulitis and abscesses. A high index of suspicion resulting from the lab-oratory risk indicator for necrotizing fasciitis score can facilitate early diagnosis enabling prompt antibiotic administration and timely referral to surgery for wound debridement, ultimately reducing both the morbidity and mortality.

    2012-01-01

    Full Text Available Hepatic encephalopathy can be a serious complication of acute liver failure and chronic liver diseases, predominantly liver cirrhosis. Hyperammonemia plays the most important role in the pathogenesis of hepatic encephalopathy. The brain-blood barrier disturbances, changes in neurotransmission, neuroinflammation, oxidative stress, GABA-ergic or benzodiazepine pathway abnormalities, manganese neurotoxicity, brain energetic disturbances, and brain blood flow abnormalities are considered to be involved in the development of hepatic encephalopathy. The influence of small intestine bacterial overgrowth (SIBO on the induction of minimal hepatic encephalopathy is recently emphasized. The aim of this paper is to present the current views on the pathogenesis of hepatic encephalopathy.

  20. The clinical and imaging characteristics of delayed encephalopathy after acute carbon monoxide poisoning

    Objective: To discuss the clinical and imaging characteristics of delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: The clinical data of 14 patients with DEACMP were respectively analyzed. Results: Initial symptom included mentally falling (MMSE rate < 20 points) in 14 patients (100%), incontinence of urine in 11 patients (78%). Relatively significant increase of hematoma (HCT) (average level 0.503±0.027) was found in 6 patients. Three kinds of brain magnetic resonance imaging (MRI) appearance including diffuse white matter lesion, cortical lesion and basal nuclei lesion often existed in association. Therapy for improving circulation was given in 14 patients, and therapy with hormone was given in 9 patients; with 85% improvement rate. 5 patients without hormone therapy but with improving circulation therapy also received improvement. Conclusion: High level of HCT might be one of the causes of DECACMP due to acute disturbance of brain micro-circulation.. Close monitoring the change of HCT levels should be adopted for at least 3-6 months during therapy. Therapy for improving circulation and for anti-agglutination of platelets should be performed besides the routine high-tension oxygen therapy. Low FA value on DTI indicates the occurrence of a demyelization change in the brain long tract fibers, which indicated therapeutic effect of hormone treatment. And, therefore it would be better to perform DTI scan before therapy for individualized therapy. (authors)

    2014-12-01

    A previously healthy 48-year-old woman was evaluated for lightheadedness and chest heaviness 2 weeks after starting the herbal supplement Garcinia cambogia. She was found to be hypotensive and had an elevated serum troponin level. The patient had a progressive clinical decline, ultimately experiencing fulminant heart failure and sustained ventricular arrhythmias, which required extracorporeal membrane oxygenation support. Endomyocardial biopsy results were consistent with acute necrotizing eosinophilic myocarditis (ANEM). High-dose corticosteroids were initiated promptly and her condition rapidly improved, with almost complete cardiac recovery 1 week later. In conclusion, we have described a case of ANEM associated with the use of Garcinia cambogia extract. PMID:25475477

  2. Acute intermittent porphyria leading to posterior reversible encephalopathy syndrome (PRES): a rare cause of abdominal pain and seizures.

    Dagens, Andrew; Gilhooley, Michael James

    2016-01-01

    Acute intermittent porphyria (AIP) is an inherited deficiency in the haem biosynthesis pathway. AIP is rare, affecting around 1 in 75 000 people. Acute attacks are characterised by abdominal pain associated with autonomic, neurological and psychiatric symptoms. AIP is rarely associated with posterior reversible encephalopathy syndrome (PRES). PRES is a clinicoradiological condition caused by the failure of the posterior circulation to autoregulate, resulting in cerebral oedema, headaches, nausea and seizures. This association is important because drugs used in the management of seizures may worsen an attack of AIP. This article describes a case of AIP and PRES in a young woman. PMID:27277587

    Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) at onset manifests an early seizure (ES) usually lasting more than 30 min. Following ES, some patients exhibit almost clear consciousness with no neurological symptoms, and no MRI abnormality for a few days, which may lead to an initial misdiagnosis of prolonged febrile seizures (PFS). To allow an early diagnosis of AESD, we retrospectively analyzed clinical manifestations, laboratory data, and radiologic and EEG findings in patients with AESD (n=62) having ES of over 30 min, and ones with PFS (n=54), using logistic regression analyses. Multivariate logistic regression analysis revealed that an age below 1.5 years and a Glasgow Coma Scale score of 14 or less than 14 (Japan Coma Scale score of 1 or higher) were high risk factors of developing AESD. We proposed an AESD prediction score system consisting of consciousness level, age, duration of convulsions, enforcement of mechanical intubation, and aspartate aminotransferase, blood glucose and creatinine levels (full score: 9), the mean scores in AESD and PFS being 5.9 and 1.8, which were significantly different (psystem for differentiating patients with AESD and PFS around the time of ES (score of 4 or more than 4 suggesting AESD), which may contribute to early therapeutic intervention and an improved neurologic outcome.

    Full Text Available Abstract Introduction Patients with clinically mild encephalitis/encephalopathy with a reversible splenial lesion present with relatively mild central nervous system disturbances. Although the exact etiology of the condition remains poorly understood, it is thought to be associated with infective agents. We present a case of a patient with mild encephalitis/encephalopathy with a reversible splenial lesion, who had the unusual feature of acute urinary retention. Case presentation A 23-year-old Japanese woman developed mild confusion, gait ataxia, and urinary retention seven days after onset of fever and headache. Magnetic resonance imaging demonstrated T2 prolongation in the splenium of the corpus callosum and bilateral cerebral white matter. These magnetic resonance imaging abnormalities disappeared two weeks later, and all of the symptoms resolved completely within four weeks. Except for the presence of acute urinary retention (due to underactive detrusor without hyper-reflexia, the clinical and radiologic features of our patient were consistent with those of previously reported patients with mild encephalitis/encephalopathy with a reversible splenial lesion. To the best of our knowledge, this is the first report of acute urinary retention recognized in a patient with mild encephalitis/encephalopathy with a reversible splenial lesion. Conclusion Our findings suggest that mild encephalitis/encephalopathy with a reversible splenial lesion can be associated with impaired bladder function and indicate that acute urinary retention in this benign disorder should be treated immediately to avoid bladder injury.

  7. Quantitative analysis of brain metabolites concentrations using MR spectroscopy in acute hypoxia ischemic encephalopathy

    Objective: To evaluate the absolute quantification of brain metabolites concentrations using external standard MRS in acute hypoxia ischemia encephalopathy (HIE) piglet model. Method: Eight 7-day-old healthy piglets were subjected to insult of hypoxia ischemia (HI). The animals and an external standard phantom containing detectable metabolites of known concentrations were studied on a 1.5 T GE Signa scanner. The single-voxel proton magnetic resonance spectroscopy (1H-MRS) data were processed using LCModel software, and the quantification of N-acetylaspartate (NAA), creatine (Cr) and lactate (Lac) were accomplished. Multivariate analysis of variance was performed to compare the NAA, Cr, Lac concentration differences in the brains of piglets pre- and post-HI (0h). In addition, the dynamic changes of brain metabolites concentrations of 2 HIE piglets were observed at the time points of 0 h and 2 h. Results: One piglet was excluded because it was over anesthetized to death. Seven piglets' data were analyzed. The concentrations of NAA pre- and post-HI were (6.86±0.49) mmol/kg and (5.73±0.88) mmol/kg respectively, they were (4.65±0.73) mmol/kg and (4.40±0.80) mmol/kg for Cr; and were 0.00 mmol/kg and (0.43±0.39) mmol/kg for Lac. After HI, decreased NAA concentration immediately was observed, and it was of statistical significance (F=8.608, P=0.013). The concentration of Cr was insignificantly decreased (F=0.379, P=0.550). The concentration of Lac was increased, and the difference was of statistical significance (F=8.600, P=0.013). Dynamic observation showed a Lac peak immediately after HI and it decreased after 2 h post-HI. Conclusions: External standard MRS using LCModel has great value in the quantitative analysis of brain metabolites. The changes of NAA and Lac concentrations are sensitive to reflect the early metabolic change of acute HIE. (authors)

  9. Multiple Pancreaticoduodenal Penetrating Gunshot Trauma Evolving into Acute Necrotizing Pancreatitis. A Combined Surgical and Minimally Invasive Approach

    Mario Testini

    2008-09-01

    Full Text Available Context Shotgun injuries are the cause of increasing surgical problems related to the proliferation of firearms. Gunshot pancreaticoduodenal traumas are unusual in urban trauma units. Their management remains complex because of the absence of standardized, universal guidelines for treatment and the high incidence of associated lesions of major vessels as well as of other gastrointestinal structures. Surgical treatment is still controversial, and the possibilities offered by the safe and effective miniinvasive techniques seem to open new, articulated perspectives for the treatment of pancreaticoduodenal injury complications. Case report We present the case of a 27- year-old man with multiple penetrating gunshot trauma evolving into acute necrotizing pancreatitis, treated by combining a surgical with a mini-invasive approach. At admission, he presented a Glasgow Coma Score of 4 due to severe hemorrhagic shock. First, surgical hemostasis, duodenogastric resection, multiple intestinal resections, peripancreatic and thoracic drainage were carried out as emergency procedures. On the 12th postoperative day, the patient underwent re-surgery with toilette, external duodenal drainage with Foley tube and peripancreatic drainage repositioning as a result of a duodenal perforation due to acute necrotizing pancreatitis. Eight days later, following the accidental removal of the peripancreatic drains, a CT scan was done showing a considerable collection of fluid in the epiploon retrocavity. Percutaneous CT-guided drainage was performed by inserting an 8.5 Fr pigtail catheter, thus avoiding further reoperation. The patient was successfully discharged on the 80th postoperative day. Conclusions The treatment of multiple pancreaticoduodenal penetrating gunshot traumas should focus on multidisciplinary surgical and minimally invasive treatment to optimize organ recovery.

    Posterior reversible encephalopathy represents a neurotoxic state which can be associated to different pathological situations. The key to diagnosis are characteristic features on magnetic resonance imaging and rapidly evolving neurological symptoms if recognized and treated rapidly. Arterial hypertension and preeclampsia are the main causes of posterior reversible encephalopathy. Metabolic disorders including renal failure can also be associated with this syndrome. We report the clinical observation of an 18-year-old young patient on chronic hemodialysis who presented a status epilepticus associated with hypertensive crisis, two weeks after his transfer to peritoneal dialysis. Magnetic resonance imaging showed a typical aspect of posterior reversible encephalopathy with intracerebral haemorrhage. The evolution was favorable with a clear improvement of encephalic lesions.

    Acute non-necrotizing cellulitis is a skin infection with a tendency to recur. Both general and local risk factors for erysipelas or cellulitis have been recognized in previous studies using hospitalized controls. The aim of this study was to identify risk factors for cellulitis using controls recruited from the general population. We also compared patients with a history of previous cellulitis with those suffering a single episode, with regard to the risk factors: length of stay in hospital, duration of fever, and inflammatory response as measured by C-reactive protein (CRP) level and leukocyte count. Ninety hospitalized cellulitis patients and 90 population controls matched for age and sex were interviewed and clinically examined during the period April 2004 to March 2005. In multivariate analysis, chronic oedema of the extremity, disruption of the cutaneous barrier and obesity were independently associated with acute cellulitis. Forty-four (49%) patients had a positive history (PH) of at least one cellulitis episode before entering the study. Obesity and previous ipsilateral surgical procedure were statistically significantly more common in PH patients, whereas a recent (<1 month) traumatic wound was more common in patients with a negative history (NH) of cellulitis. PH patients had longer duration of fever and hospital stay, and their CRP and leukocyte values more often peaked at a high level than those of NH patients. Oedema, broken skin and obesity are risk factors for acute cellulitis. The inflammatory response as indicated by CRP level and leukocyte count is statistically significantly more severe in PH than NH patients. PMID:19694769

    @@ 小儿急性坏死性胰腺炎是一种少见疾病(1),我院小儿外科近几年收治了2例重型患儿,经过积极手术治疗,均获痊愈.%Two children with acute necrotizing pancreatitis were treated by aggressive surgical intervention,and survived.The sequelae of this condition are also outlined.It is concluded that acute necrotizing pancreatitis should be considered when a child complains of upper abdominal pain,bloody ascites,acute onset and signs of peritoneal irritability.The serum and urine amylase determination should be imminent,wh1ch is helpful in confirming the diagnosis and lend to earlier surgical intervend tion.Once exploratory laporotomy has ruled out the biliary diseaseas as the original cause,wide debridement of the necrotic gland tissue and removal of the adjacent abscess and external drainage are indicated.Gastrotomy and cholecystomy for decompression and jejunostomy for early tube feeding are necessary.After one week,re-debridement through the patient's wound is recommended.

  16. Role of central nervous system in acute radiation syndrome functional metabolic encephalopathy

    In adult rabbit, the effect on the brain of a whole-body or encephalic gamma irradiation is a function of the absorbed dose and begins after 25 rads. Three phases are described in the mechanism of radiation effect. In the initial phase, irradiation acts as a direct stimulus of cerebral structures. The second phase is a response towards aggression which includes: the effect of stimulation of various cerebral structures; their response and the induced feed-back mechanism; the release of metabolites inducing a functional metabolic encephalopathy in which occur: modification of blood pressure; modification of pulmonary ventilation; modification of acido-basic blood equilibrium. The third phase consists of functional recovery

    AIM: In previous experiments we have demonstrated that by administering low doses of cholecystokinin-octapeptide (CCK-8), the process of regeneration following L-arginine (Arg)-induced pancreatitis is accelerated. In rats that were also diabetic (induced by streptozotocin, STZ), pancreatic regeneration was not observed. The aim of this study was to deduce whether the administration of exogenous insulin could in fact restore the hypertrophic effect of CCK-8 in diabetic-pancreatitic rats.METHODS: Male Wistar rats were used for the experiments.Diabetes mellitus was induced by administering 60 mg/kg body mass of STZ intraperitoneally (i.p.), then, on d 8,pancreatitis was induced by 200 mg/100 g body mass Arg i.p. twice at an interval of 1 h. The animals were injected subcutaneously twice daily (at 7 a.m. and 7 p.m.) with 1 μg/kg of CCK-8 and/or 2 IU mixed insulin (300 g/L shortaction and 700 g/L intermediate-action insulin) for 14 d after pancreatitis induction. Following this the animals were killed and the serum amylase, glucose and insulin levels as well as the plasma glucagon levels, the pancreatic mass/body mass ratio (pm/bm), the pancreatic contents of DNA, protein, amylase, lipase and trypsinogen were measured. Pancreatic tissue samples were examined by light microscopy on paraffin-embedded sections.RESULTS: In the diabetic-pancreatitic rats treatment with insulin and CCK-8 significantly elevated pw/bm and the pancreatic contents of protein, amylase and lipase vs the rats receiving only CCK-8 treatment. CCK-8 administered in combination with insulin also elevated the number of acinar cells with mitotic activities, whereas CCK-8 alone had no effect on laboratory parameters or the mitotic activities in diabetic-pancreatitic rats.CONCLUSION: Despite the hypertrophic effect of CCK-8 being absent following acute pancreatitis in diabetic-rats,the simultaneous administration of exogenous insulin restored this effect. Our results clearly demonstrate that insulin is

    Objective To observe sulfhydryl compound variation in the injury of pancreatic cells and the effects of external sulfhydryl compounds on cytoprotection.Methods Male Wistar mice were divided randomly into three groups: groups A and B served as animal models (retrograde duct infusion with 5% sodium taurocholate), in group A, 45 animals were treated with normal saline therapy, in group B, 45 aminals were treated with Tiopronin therapy; and group C, 15 animals, were designated as normal control. Animals were killed at 2, 4, 6, 12 and 24 h, and pancreatic tissue was analyzed for total sulfhydryl (TSH), nonprotein sulfhydryl (NPSH) and malondialdehyde (MDA). Histopathology, serum amylase (Sam) and C reactive protein (CRP) were assessed as well.Results Levels of Sam and CRP increased in both group A and group B, with corresponding pathological changes of acute nerotic pancreatitis (ANP). Levels of TSH, NPSH and protein sulfhydryl (PSH) in group A decreased markedly during pancreatitis (P<0.01), but MDA increased significantly (P<0.01). The depletion of NPSH in group B was markedly ameliorated at 4 h or 6 h, when Tiopronin was prophylactically administered (P<0.05), after which the level of MDA showed very little increase when compared to group A (P<0.01). Histopathological damage was attenuated to a certain extent, in regards to serum amylase and CRP.Conclusions All sulfhydryl compounds decreased significantly during ANP; external sulfhydryl compound could protect the pancreatic cells most likely as a type of scavengers of oxygen free radicals, which are critically involved in the pathophysiology of ANP. Sulfhydryl plays an important role in the action of pancreatic cytoprotection.

  20. Effect of an acute necrotic bacterial gill infection and feed deprivation on the metabolic rate of Atlantic salmon Salmo salar.

    Jones, M A; Powell, M D; Becker, J A; Carter, C G

    2007-10-31

    In this study, experiments were conducted to examine the effect of an acute necrotic bacterial gill infection on the metabolic rate (M(O2)) of Atlantic salmon Salmo salar. Fed and unfed Atlantic salmon smolts were exposed to a high concentration (5 x 10(12) CFU ml(-1)) of the bacteria Tenacibaculum maritimum, their routine and maximum metabolic rates (M(O2rout) and M(O2max), respectively) were measured, and relative metabolic scope determined. A significant decrease in metabolic scope was found for both fed and unfed infected groups. Fed infected fish had a mean +/- standard error of the mean (SEM) decrease of 2.21 +/- 0.97 microM O2 g(-1) h(-1), whilst unfed fish a mean +/- SEM decrease of 3.16 +/- 1.29 microM O2 g(-1) h(-1). The decrease in metabolic scope was a result of significantly increased M(O2rout) of both fed and unfed infected salmon. Fed infected fish had a mean +/- SEM increase in M(O2rout) of 1.86 +/- 0.66 microM O2 g(-1) h(-1), whilst unfed infected fish had a mean +/- SEM increase of 2.16 +/- 0.72 microM O2 g(-1) h(-1). Interestingly, all groups maintained M(O2max) regardless of infection status. Increases in M(O2rout) corresponded to a significant increase in blood plasma osmolality. A decrease in metabolic scope has implications for how individuals allocate energy; fish with smaller metabolic scope will have less energy to allocate to functions such as growth, reproduction and immune response, which may adversely affect the efficiency of fish growth.

  1. Isolated acute non-cystic white matter injury in term infants presenting with neonatal encephalopathy.

    Barrett, Michael Joseph

    2013-03-01

    We discuss possible aetiological factors, MRI evolution of injury and neuro-developmental outcomes of neonatal encephalopathy (NE). Thirty-six consecutive infants diagnosed with NE were included. In this cohort, four infants (11%) were identified with injury predominantly in the deep white matter on MRI who were significantly of younger gestation, lower birthweight with higher Apgars at one and five minutes compared to controls. Placental high grade villitis of unknown aetiology (VUA) was identified in all four of these infants. Our hypothesis states VUA may induce white matter injury by causing a local inflammatory response and\\/or oxidative stress during the perinatal period. We underline the importance of continued close and systematic evaluation of all cases of NE, including examination of the placenta, in order to come to a better understanding of the clinical presentation, the patterns of brain injury and the underlying pathophysiological processes.

  2. Necrotizing Fasciitis

    2013-01-01

    Full Text Available Necrotizing fasciitis (NF is among the most challenging surgical infections faced by a surgeon. The difficulty in managing this entity is due to a combination of difficulty in diagnosis, and also of early as well as late management. For the patient, such a diagnosis means prolonged hospital stay, painful dressings, an extended recovery, and in some unfortunate cases even loss of limb or life. Necrotizing fasciitis is a fairly common condition in surgical practice in the Indian context resulting in a fairly large body of clinical experience. This article reviews literature on MEDLINE with the key words ′′necrotizing,′′ ′′fasciitis,′′ and ′′necrotizing infections′′ from 1970, as well as from articles cross referenced therein. The authors attempt to draw comparisons to their own experience in managing this condition to give an Indian perspective to the condition.

  3. DNA pooling base genome-wide association study identifies variants at NRXN3 associated with delayed encephalopathy after acute carbon monoxide poisoning.

    Wenqiang Li

    Full Text Available Delayed encephalopathy after acute carbon monoxide poisoning (DEACMP is more characteristic of anoxic encephalopathy than of other types of anoxia. Those who have the same poisoning degree and are of similar age and gender have a greater risk of getting DEACMP. This has made it clear that there are obvious personal differences. Genetic factors may play a very important role. The authors performed a genome-wide association study involving pooling of DNA obtained from 175 patients and 244 matched acute carbon monoxide poisoning without delayed encephalopathy controls. The Illumina HumanHap 660 Chip array was used for DNA pools. Allele frequencies of all SNPs were compared between delayed encephalopathy after acute carbon monoxide poisoning and control groups and ranked. A total of 123 SNPs gave an OR >1.4. Of these, 46 mapped in or close to known genes. Forty-eight SNPs located in 19 genes were associated with DEACMP after correction for 5% FDR in the genome-wide association of pooled DNA. Two SNPs (rs11845632 and rs2196447 locate in the Neurexin 3 gene were selected for individual genotyping in all samples and another cohort consisted of 234 and 271 controls. There were significant differences in the genotype and allele frequencies of rs11845632 and rs2196447 between the DEACMP group and controls group (all P-values <0.05. This study describes a positive association between Neurexin 3 and controls in the Han Chinese population, and provides genetic evidence to support the susceptibility of DEACMP, which may be the resulting interaction of environmental and genetic factors.

    Full Text Available Background: Acute febrile encephalopathy (AFE is a clinical term used to an altered mental state that either accompanies or follows a short febrile illness and is characterized by a diffuse and nonspecific brain insult manifested by a combination of coma, seizures, and decerebration. Objective: To identify the etiological diagnosis and outcome in adult patients with AFE. Settings and Design: A prospective observational study was done in patients aged 14 years or above who were admitted with AFE at a tertiary care center in northwest India. Materials and Methods: The non-infectious causes of unconsciousness were excluded and then only a diagnosis of AFE was considered. Cerebrospinal fluid (CSF analysis and imaging of brain was done to determine the possible etiology. Outcome was assessed at 1 month of follow-up after discharge by using modified Rankin Scale (mRS. Data were analyzed and presented as mean, median, and percentages. A P value of 3 in 14 patients with AVE (P 3 in six patients with AVE and in the rest it was ≤1 (P < 0.001. Conclusions: In this study, pyogenic meningitis was the leading cause of AFE, followed by AVE and cerebral malaria. The outcome in cases with AVE can be fatal or more disabling than other etiologies.

    Full Text Available Introduction: Necrotizing sialometaplasia (NSM is a benign lesion affecting the salivary glands mainly in the hard palate. It presents as an ulcer with irregular borders, slightly elevated and necrotic The differential diagnosis should include malignant neoplasms. Case Report: A 26-year-old woman sought medical advice for a painful 2 cm ulceration of the hard palate. She is carrying pierced tongue. The patient had a history of cigarette smoking, chronic anxiety disorder and bulimia,. Analytical normal (including HIV and syphilis serology. Histopathology: accessory gland with squamous metaplasia, pseudoepitheliomatous hyperplasia and conservation lobulararchitecture. She had an important improvement with total resolution of the lesion in 4 months Discussion: The NSM is a necrotizing inflammatory process. It presents as an ulcer located in the posterior hard palate or the junction between the hard and soft palate. This situation has been associated with local ischemia as surgical trauma, thromboangiitis obliterans, dentures, alcohol, snuff, cocaine, and certain malignancies such as lymphomas, rhabdomyosarcoma or Warthin tumor. Currently associated withbulimia, it being necessary suspected in young women. It is important to rule out neoplasms and infectious processes (tuberculosis or syphilis. Also consider subacute necrotizing sialadenitis, nonspecific acute inflammatory process of unknown cause, with focal necrosis without hyperplasia or ductal metaplasia pseudoepitheliomatous. Treatment is symptomatic and usually resolves in 2-3 months. Conclusion: The NSM is a benign lesion which may mimic neoplasia. The trend is toward resolution. It must be recognized to avoid unnecessary surgery.

  10. An experimental model of acute encephalopathy after total body irradiation in the rat: effect of Ginkgo biloba extract (EGb 761)

    To define the therapeutic effect of Ginkgo biloba extract (EGb 761) in an experimental model of acute encephalopathy following total body irradiation in rats. Ninety four-month-old rats received 4.5 Gy total body irradiation (TBI) at day 1 while 15 rats received sham irradiation. A behavioural study based on a conditioning test of negative reinforcement, the one-way avoidance test, was performed test, was performed after irradiation. Orally treatment was started one day (study A) or twenty two days (study B) after irradiation and repeated daily for twelve days. In the irradiated group, three subgroups were defined according to the treatment received: EGb 761 (50 mg/kg), EGb 761 (100 mg/kg), water. This work comprised two consecutive studies. In study A (45 rats) the one-way avoidance test was administered daily from day 7 to day 14. In study B (45 rats) the behavioural test was performed from day 28 to day 35. Study A (three groups of 15 rats): following TBI, irradiated rats treated with water demonstrated a significant delay in a learning the one-way avoidance test in comparison with sham-irradiated rats (P < 0.0002) or irradiated rats treated with EGb 761 (50 mg/kg; P < 0.007) or EGb 761 (100 mg/kg; P < 0.0002). The irradiated rats, treated with EGb 761 (50 or 100 mg/kg) did not differ from the sham-irradiated controls.

    2011-01-01

    Introduction Pediatric acute liver failure (ALF) is often accompanied by hepatic encephalopathy, cerebral edema and raised intracranial pressure (ICP). Elevated ICP can be managed more effectively with intracranial monitoring, but ALF-associated coagulopathy is often considered a contraindication for invasive monitoring due to risk for intracranial bleeding. We reviewed our experience with use of early ICP monitoring in ALF in children listed for liver transplantation. Methods Retrospective review of all intubated pediatric ALF patients with Grade 3 and Grade 4 encephalopathy requiring intracranial pressure monitoring and evaluated for potential liver transplant were identified from an institutional liver transplant patient database from 1999 to 2009. Result 14 patients were identified that met inclusion criteria. Age ranged from 7 months to 20 yrs. Diagnoses of ALF were infectious (3), drug induced (7), autoimmune hepatitis (2) and indeterminate (2). Grade 3 and 4 encephalopathy was seen in 10 (71%) and 4 (29%) patients respectively. CT scans prior to ICP monitor placement showed cerebral edema in 5 (35.7%) patients. Prior to ICP monitor placement, fresh frozen plasma, Vitamin K and activated recombinant factor VIIa were given to all 14 patients with significant improvement in coagulopathy (pliver transplant with 100% surviving neurologically intact. 4/14 (28%) patients had spontaneous recovery without liver transplant. 2 of 14 (14%) patients died due to multiple organ failure prior to transplant. One patient had a small 9mm intracranial hemorrhage but survived after receiving a liver transplant. No patient developed intracranial infection. Conclusion In our series of patients, ICP monitoring had a low complication rate and was associated with a high survival rate despite severe hepatic encephalopathy and cerebral edema in the setting of pediatric ALF. In our experience, monitoring of ICP allowed interventions to treat increased ICP and provided additional

It can be defined as a neuropsychiatric syndrome caused by portosystemic venous shunting, ranging from minimal to overt hepatic encephalopathy or coma. Its pathophysiology is still unclear, although increased levels of ammonia play a key role. Diagnosis of hepatic encephalopathy is currently based on specific tests evaluating the neuropsychiatric state of patients and their quality of life; the severity of hepatic encephalopathy is measured by the West Haven criteria. Treatment of hepatic encephalopathy consists of pharmacological and corrective measures, as well as nutritional interventions. Rifaximin received approval for the treatment of hepatic encephalopathy in 2010 because of its few side effects and pharmacological benefits. The aim of this work is to review the use and efficacy of rifaximin both in acute and long-term management of hepatic encephalopathy. Treatment of overt hepatic encephalopathy involves management of the acute episode as well as maintenance of remission in those patients who have previously experienced an episode, in order to improve their quality of life. The positive effect of rifaximin in reducing health care costs is also discussed.Keywords: acute hepatic encephalopathy, recurrent hepatic encephalopathy, rifaximin, lactulose, cost, health-related quality of life

  13. Classical, Minimally Invasive Necrosectomy or Percutaneous Drainage in Acute Necrotizing Pancreatitis. Does Changing the Order of the Factors Change the Result?

    Generoso Uomo

    2010-07-01

    Full Text Available Over the last years many international surveys have witnessed a substantial reduction of the mortality rate in severe acute pancreatitis [1, 2, 3, 4, 5, 6]. Several factors, such as a better identification and characterization of patients having the poorest prognosis, improvement of intensive care measures, and a clearer definition of the indication/timing of surgery play a significant role in this positive scenario. In this regard the avoidance of early intervention to allow resuscitation, stabilization, and demarcation of the necrotic areas and innovations in drainage and evacuation of fluid and devitalized tissues represent important steps in the evolution of therapeutic strategies in acute pancreatitis [7, 8]. In the recent past, the most important controversies in the field of the surgical treatment of necrotizing acute pancreatitis are mainly related to the approach to be used in patients with sterile necrosis and to the choice between the different techniques of necrosectomy/drainage. The first topic still remains uncertain and, independently from what has been suggested by international guidelines/recommendations, the clinician’s expertise or the attitude of the individual working-care group guides the definitive management in daily clinical practice [9]. As regards the surgical procedure of necrosectomy/drainage, the choice is mainly between the open necrosectomy with open packing and planned re-laparotomy/lavage [10, 11] and with open necrosectomy followed by continuous closed lavage of the lesser sac and retroperitoneum [12, 13, 14, 15]. Percutaneous catheter drainage through an anterior or retroperitoneal approach (guided by CT scan or ultrasound was mainly considered over the last years to be complementary to an intensive care support in unstable patients, often as a bridging procedure able to delay surgery [16, 17, 18]. The best results with this procedure were achieved in draining pus or fluid collections whereas debridement of

  14. Computed tomography of delayed encephalopathy of acute carbon monoxide poisoning - correlation with clinical findings -

    Cerebral computed tomography (CT) findings were described in twenty-six cases with the late sequelae of acute carbon monoxide poisoning and were computed with the neurological symptoms and signs. The CT findings include symmetrical periventricular white matter low density in five cases, globes pallidus low density in six cases, ventricular dilatation in seven cases, ventricular dilatation and sulci widening in three cases, and normal findings in ten cases. Only one case showed low densities in both periventricular white matter and globes pallidus. Late sequelae of the interval from of carbon monoxide poisoning were clinically categorized as cortical dysfunction, parkinsonian feature, and cerebella dysfunction. The severity of the clinical symptoms and signs of neurological sequelae is generally correlated with presence and multiplicity of abnormal brain CT findings. But of fourteen cases showing the parkinsonian feature, only five cases had low density of globes pallidus in brain CT. Another case showing small unilateral low density of globes pallidus had no parkinsonian feature but showed mild cortical dysfunction.

    Anti-PD-1 inhibitors have significant activity in metastatic melanoma. Responses often occur early and may be sustained. The optimal duration of treatment with these agents is unknown. Here, we report the case of a 51-year-old woman treated with pembrolizumab, as part of the Keynote-001 trial, as first-line treatment for metastatic disease. She experienced a complete response after 13.8 months of treatment with no adverse events. One month after the last drug infusion and 18 months from starting treatment, the patient presented with eosinophilic fasciitis. She then developed acute confusion and weakness, thought to be due to intracranial vasculitis. High-dose steroids were initiated with resolution of the fasciitis. Aspirin was commenced for presumed vasculitis with resolution of the neurologic symptoms. To our knowledge, there are no previous reports of eosinophilic fasciitis or cerebral vasculitis due to anti-PD-1 agents. This case demonstrates that toxicity may occur in association with pembrolizumab treatment after a prolonged period of treatment without toxicity. Future trials should explore the optimal duration of treatment with pembrolizumab. PMID:26822024

    Full Text Available Abstract Background Acute encephalopathy includes rapid deterioration and has a poor prognosis. Early intervention is essential to prevent progression of the disease and subsequent neurologic complications. However, in the acute period, true encephalopathy cannot easily be differentiated from febrile seizures, especially febrile seizures of the complex type. Thus, an early diagnostic marker has been sought in order to enable early intervention. The purpose of this study was to identify a novel marker candidate protein differentially expressed in the cerebrospinal fluid (CSF of children with encephalopathy using proteomic analysis. Methods For detection of biomarkers, CSF samples were obtained from 13 children with acute encephalopathy and 42 children with febrile seizure. Mass spectral data were generated by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS technology, which is currently applied in many fields of biological and medical sciences. Diagnosis was made by at least two pediatric neurologists based on the clinical findings and routine examinations. All specimens were collected for diagnostic tests and the remaining portion of the specimens were used for the SELDI-TOF MS investigations. Results In experiment 1, CSF from patients with febrile seizures (n = 28, patients with encephalopathy (n = 8 (including influenza encephalopathy (n = 3, encephalopathy due to rotavirus (n = 1, human herpes virus 6 (n = 1 were used for the SELDI analysis. In experiment 2, SELDI analysis was performed on CSF from a second set of febrile seizure patients (n = 14 and encephalopathy patients (n = 5. We found that the peak with an m/z of 4810 contributed the most to the separation of the two groups. After purification and identification of the 4.8-kDa protein, a 4.8-kDa proteolytic peptide fragment from the neurosecretory protein VGF precursor (VGF4.8 was identified as a novel biomarker for encephalopathy.

    Full Text Available La pancreatitis necrotizante es una causa infrecuente de muerte súbita. La metadona, un fármaco empleado en el tratamiento sustitutivo de adictos a opiáceos, ha sido responsable de muertes tras su ingestión accidental por niños cuando estaba a su alcance, en intentos autolíticos o después de un período de abstinencia en pacientes con tolerancia. La muerte se debe a depresión del sistema nervioso central y depresión respiratoria. Reportamos un caso de muerte súbita con pancreatitis aguda necrotizante y hemorrágica, hemorragia suprarrenal y edema pulmonar en el contexto de una sobredosis por metadona en un paciente en programa de mantenimiento. Se descartaron otras causas frecuentes de pancreatitis como el alcoholismo crónico o la patología de tracto biliar. Discutimos la constelación de hallazgos para sugerir un posible mecanismo fisiopatológico.Necrotic pancreatitis is a rare cause of sudden death. Methadone, a drug used as a substitution treatment in heroin addicts, has been responsible for deaths after accidental ingestion by children of carelessly stored methadone, in suicide attempts or after a period of abstinence in tolerant patients. Death results from central nervous system and respiratory depression. We report a case of a sudden death with acute hemorrhagic and necrotizing pancreatitis, suprarenal haemorrhagia and pulmonary edema in the context of an overdose of methadone in a patient in an opioid maintenance program. Other frequent causes of pancreatitis such as chronic alcoholism and biliary tract disease were ruled out. We discuss the constellation of findings with regard to possible pathophysiological mechanisms.

    Several studies have shown that acute fluoride (F(-)) exposure impairs cardiac function, but the molecular mechanism is not clear. In order to study this, male Wistar rats were treated with single oral doses of 45 and 90 mg/kg F(-) for 24 h. A significant accumulation of F(-) was found in the serum and myocardium of experimental rats. F(-) treatment causes myocardial necrosis as evident from increased levels of myocardial troponin I, creatine kinase, lactate dehydrogenase and aspartate transaminase. In addition, F(-) induces myocardial oxidative stress via increased reactive oxygen species, lipid peroxidation, protein carbonyl content and nitrate levels along with decreased in the levels of enzymatic (superoxide dismutase 2, catalase, glutathione peroxidase and glutathione s transferase pi class) and non-enzymatic (reduced glutathione) antioxidants. Notably, F(-) triggers myocardial apoptosis through altered Bax/Bcl2 ratio and increased cytochrome c, caspase 3p20 and terminal deoxynucleotidyl transferase dUTP nick end labeled positive cells. An increased cardiac expression of Nox4 and p38α MAPK in F(-) treated rats indicates the oxidative and apoptotic damage. Moreover, ultra-structural changes, histopathological and luxol fast blue staining demonstrates the degree of myocardial damage at subcellular level. Taken together, these findings reveal that acute F(-) exposure causes cardiac impairment by altering the expression of oxidative stress, apoptosis and necrotic markers. PMID:26455266

  8. The diagnostic value of apparent diffusion coefficient value on the delayed encephalopathy after acute carbon monoxide poisoning

    Objective: To investigate the diagnostic value of ADC on delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: Forty healthy subjects with normal head MRI appearance and 32 cases with DEACMP were recruited and scanned using MRI. ADC values in bilateral globus pallidus, cerebral white matter (peri-ventricle, centrum semioval) and cortex were measured respectively. According to conventional MRI, 32 DEACMP patients were divided into abnormal and normal signal intensity groups, and followed up more than one year. Thirteen cases without evident symptoms and 3 cases with little headache and dizziness were good prognosis group. Fifteen cases with disturbance of intelligence and mental anomaly and one case with manifested unresponsive, inability in life self-care, urinary and fecal incontinence were poor prognosis group. Independent samples t-test was used to compared all parts of brain ADC values between DEACMP group and normal control, abnormal and normal signal intensity groups, normal signal intensity group and normal control, good and poor prognosis groups. Results: According to MRI findings, DEACMP were classified into three types: type 1: showing white matter involvement; type 2: showing neural nuclei involvement and type 3: showing brain cortex involvement. The ADC values [peri-ventricle white matter (0.62±0.06) x 10-3 mm2/s, the globus pallidus (0.67± 0.05) x 10-3 mm2/s, centrum semioval(0.57±0.07) x 10-3 mm2/s] in DEACMP group were statistically different with those [(0.74±0.03) x 10-3, (0.74±0.04) x 10-3, (0.73±0.05) x 10-3 mm2/s] in normal people (t=2.82,2.89,2.98, P-3 mm2/s, centrum semioval(0.52±0.09) x 10-3 mm2/s] in 20 cases with abnormal signal on routine MRI were statistically different with the ADC values [(0.66±0.05) x 10-3, (0.62±0.06) x 10-3 mm2/s] in 12 cases without abnormal signal (t=4.45,3.98, P-3 mm2/s, centrum semioval (0.58±0.05) x 10-3 mm2/s] in good prognosis group, the ADC value of 16 cases [(0.56±0.02) x

    susceptibility locus (ANE1) in a family segregating recurrent ANE as an incompletely penetrant, autosomal-dominant trait. We now report that all affected individuals and obligate carriers in this family are heterozygous for a missense mutation (c.1880C-->T, p.Thr585Met) in the gene encoding the nuclear pore...... protein Ran Binding Protein 2 (RANBP2). To determine whether this mutation is the susceptibility allele, we screened controls and other patients with ANE who are unrelated to the index family. Patients from 9 of 15 additional kindreds with familial or recurrent ANE had the identical mutation. It arose de...... novo in two families and independently in several other families. Two other patients with familial ANE had different RANBP2 missense mutations that altered conserved residues. None of the three RANBP2 missense mutations were found in 19 patients with isolated ANE or in unaffected controls. We conclude...

    2007-01-01

    Background Although severe encephalopathy has been proposed as a possible contraindication to the use of noninvasive positive-pressure ventilation(NPPV),increasing clinical reports showed it was effective in patients with impaired consciousness and even coma secondary to acute respiratory failure,especially hypercapnic acute respiratory failure(HARF).To further evaluate the effectiveness and safety of NPPV for severe hypercapnic encephalopathy,a prospective case-control study was conducted at a university respiratory intensive care unit(RICU)in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)during the past 3 years.Methods Forty-three of 68 consecutive AECOPD patients requiring ventilatory support for HARF were divided into 2 groups,which were carefully matched for age,sex,COPD course,tobacco use and previous hospitalization history,according to the severity of encephalopathy,22 patients with Glasgow coma scale(GCS)0.05),but group A needed an average of 7 cmH2O higher of maximal pressure support during NPPV,and 4,4 and 7 days longer of NPPV time,RICU stay and hospital stay respectively than group B(P<0.05 or P<0.01).NPPV therapy failed in 12 patients(6 in each group)because of excessive airway secretions(7 patients),hemodynamic instability(2),worsening of dyspnea and deterioration of gas exchange(2),and gastric content aspiration(1).Conclusions Selected patients with severe hypercapnic encephalopathy secondary to HARF can be treated as effectively and safely with NPPV as awake patients with HARF due to AECOPD;a trial of NPPV should be instituted to reduce the need of endotracheal intubation in patients with severe hypercapnic encephalopathy who are otherwise good candidates for NPPV due to AECOPD.

    Hepatic encephalopathy is a severe complication of liver cirrhosis and is an important therapeutic challenge, with a social and economic issue. If, now, the pathophysiology is not totally understood (main role of ammonia, but a better understanding of cerebral mechanisms), the clinical presentation is well-known. Some treatments are useful (disaccharides, treatment of the trigger) but their efficiency is limited. Nevertheless, the emergence of new treatments, such as non-absorbable antibiotics (rifaximin essentially), is an interesting therapeutic tool. PMID:26597584

    A 21-year-old male known case of primary hypothyroidism, Seizure disorder sequelae of an old trauma receiving sodium valproate, clobazam and phenobarbitone for control of Generalized tonic clonic seizures reported to neurology OPD with history of altered sensorium and gait unsteadiness for 1 week with history of hike in valproate dose 2 weeks before. On examination he was drowsy. Neurological examination was unremarkable except for gait unsteadiness and ataxia. Patient was admitted and evaluated for acute worsening. All (the) biochemical parameters including complete blood count, liver function tests, kidney function tests, routine urine examination, arterial blood gas analysis, blood and urine culture tests were normal. CSF analysis was also normal. Repeat MRI brain was also done which depicted all old changes with no fresh changes which will account for worsening of his sensorium. EEG was suggestive of diffuse encephalopathy. Thyroid function tests were also normal. Valproate encephalopathy was suspected and Valproate was empirically stopped and he was put on levetiracetam and phenytoin. His sensorium improved rapidly after stoppage of valproate with normalization of EEG. Serum valproate Levels were high with serum ammonia levels were in the normal range. We made the inference of nonhyperammoneamic valproate encephalopathy. This case highlights the existence of non-hyperammonemic valproate induced encephalopathy, suggesting mechanisms other than hyperammonemia responsible for this encephalopathy. PMID:25206067

    2016-01-01

    Cervical necrotizing fasciitis is an unusual infection characterized by necrosis of the subcutaneous tissue and fascial layers. Risk factors for the development of necrotizing fasciitis include diabetes mellitus, chronic renal disease, peripheral vascular disease, malnutrition, advanced age, obesity, alcohol abuse, intravenous drug use, surgery, and ischemic ulcers. This report presents a case of necrotizing fasciitis in the cervical area caused by dental extraction in a 73-year-old woman. Cervical necrotizing fasciitis in geriatric patient is rare, and even when establishing the diagnosis and having it timely treated, the patient can suffer irreversible damage or even death. Clinical manifestations in the head and neck usually have an acute onset characterized by severe pain, swelling, redness, erythema, presence of necrotic tissue, and in severe cases obstruction of the upper airways. Therefore, the presentation of this clinical case can serve as guidance to dentists as a precaution to maintain an aseptic chain and be aware of the clinical condition of older patients and the systemic conditions that may increase the risk of infections.

    2009-05-01

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    The NMDA type of glutamate receptors modulates learning and memory. Excessive activation of NMDA receptors leads to neuronal degeneration and death. Hyperammonemia and liver failure alter the function of NMDA receptors and of some associated signal transduction pathways. The alterations are different in acute and chronic hyperammonemia and liver failure. Acute intoxication with large doses of ammonia (and probably acute liver failure) leads to excessive NMDA receptors activation, which is responsible for ammonia-induced death. In contrast, chronic hyperammonemia induces adaptive responses resulting in impairment of signal transduction associated to NMDA receptors. The function of the glutamate-nitric oxide-cGMP pathway is impaired in brain in vivo in animal models of chronic liver failure or hyperammonemia and in homogenates from brains of patients died in hepatic encephalopathy. The impairment of this pathway leads to reduced cGMP and contributes to impaired cognitive function in hepatic encephalopathy. Learning ability is reduced in animal models of chronic liver failure and hyperammonemia and is restored by pharmacological manipulation of brain cGMP by administering phosphodiesterase inhibitors (zaprinast or sildenafil) or cGMP itself. NMDA receptors are therefore involved both in death induced by acute ammonia toxicity (and likely by acute liver failure) and in cognitive impairment in hepatic encephalopathy. PMID:17701332

    2012-11-01

    Full Text Available Context Cytomegalovirus (CMV-induced pancreatitis in patients with AIDS is a known entity with poor prognosis. Case report We report a case of a 43-year-old woman with AIDS and CMV viremia who was evaluated for hypotension and found to have severe necrotizing pancreatitis. The authors have also conducted a MEDLINE search for CMV-induced pancreatitis from 1980 to 2012 and reviewed the pertinent results. Discussion Until mid-1990s in the United States, pancreatitis due to CMV was mainly diagnosed at autopsy in AIDS patients. However, presumably due to the advent of antiretroviral therapy, there has since been a significant decline in the number of reported cases among these individuals. Rather, our review revealed that the occurrence of CMV-induced pancreatitis has since been described in a variety of clinical settings, ranging from patients on corticosteroid therapy to immunocompetent persons. Conclusions Clinicians need a high index of suspicion to timely diagnose CMV-induced pancreatitis as patients often present with non-specific signs and symptoms. As it occurred in our case, early intervention is crucial and may alter the outcome in such patients.

  1. Current concepts in the assessment and treatment of hepatic encephalopathy.

    Cash, W J

    2012-02-01

    Hepatic encephalopathy (HE) is defined as a metabolically induced, potentially reversible, functional disturbance of the brain that may occur in acute or chronic liver disease. Standardized nomenclature has been proposed but a standardized approach to the treatment, particularly of persistent, episodic and recurrent encephalopathy associated with liver cirrhosis has not been proposed. This review focuses on the pathogenesis and treatment of HE in patients with cirrhosis. The pathogenesis and treatment of hepatic encephalopathy in fulminant hepatic failure is quite different and is reviewed elsewhere.

Among the factors that contributed to encephalopathy were: Acute liver failure (73%, electrolyte imbalances (80% and shock (40%. Five (33.3% patients developed seizures. Disseminated intravascular coagulation was seen in five (33.3%. Secondary bacterial infections were observed in 8 (53.3% of our patients. The overall mortality rate was 47%.

  3. Necrotizing Pancreatitis: A Review of Multidisciplinary Management

    Anthony Sabo

    2015-05-01

    Full Text Available The objective of this review is to summarize the current state of the art of the management of necrotizing pancreatitis, and to clarify some confusing points regarding the terminology and diagnosis of necrotizing pancreatitis, as these points are essential for management decisions and communication between providers and within the literature. Acute pancreatitis varies widely in its clinical presentation. Despite the publication of the Atlanta guidelines, misuse of pancreatitis terminology continues in the literature and in clinical practice, especially regarding the local complications associated with severe acute pancreatitis. Necrotizing pancreatitis is a manifestation of severe acute pancreatitis associated with significant morbidity and mortality. Diagnosis is aided by pancreas-protocol computed tomography or magnetic resonance imaging, ideally 72 h after onset of symptoms to achieve the most accurate characterization of pancreatic necrosis. The extent of necrosis correlates well with the incidence of infected necrosis, organ failure, need for debridement, and morbidity and mortality. Having established the diagnosis of pancreatic necrosis, goals of appropriately aggressive resuscitation should be established and adhered to in a multidisciplinary approach, ideally at a high-volume pancreatic center. The role of antibiotics is determined by the presence of infected necrosis. Early enteral feeds improve outcomes compared with parenteral nutrition. Pancreatic necrosis is associated with a multitude of complications which can lead to long-term morbidity or mortality. Interventional therapy should be guided by available resources and the principle of a minimally invasive approach. When open debridement is necessary, it should be delayed at least 3-6 weeks to allow demarcation of necrotic from viable tissue

  6. Case Report of Necrotizing Fasciitis Associated with Streptococcus pneumoniae

    Lei Jiao

    2016-01-01

    Full Text Available Necrotizing fasciitis, caused by Streptococcus pneumoniae, is an extremely rare and life-threatening bacterial soft tissue infection. We report a case of early necrotizing fasciitis associated with Streptococcus pneumoniae infection in a 26-year-old man who was immunocompromised with mixed connective tissue disease. The patient presented with acute, painful, erythematous, and edematous skin lesions of his right lower back, which rapidly progressed to the right knee. The patient underwent surgical exploration, and a diagnosis of necrotizing fasciitis was confirmed by pathological evidence of necrosis of the fascia and neutrophil infiltration in tissue biopsies. Cultures of fascial tissue biopsies and blood samples were positive for Streptococcus pneumoniae. To our knowledge, this is the first report of necrotizing fasciitis resulting from Streptococcus pneumoniae diagnosed at early phase; the patient recovered well without surgical debridement.

    Necrotizing enterocolitis, which is localized only in the jejunum, is very rare and this entity cannot be found in the English medical literature. We report the computed tomographic(CT) findings of necrotizing jejunitis in a 45-year-old man, which showed ring like and mottled air shadows between the contrast filled bowel lumen and its wall, dirty mesenteric fat and prominent mesenteric vascular enhancement. We regard CT is a useful diagnostic method of necrotizing jejunitis.

  11. Mortality in necrotizing fasciitis

    The objective of this study was to determine the mortality rate in patients presenting with Necrotizing Fasciitis. This prospective study was conducted at ward 26, JPMC Karachi over a period of two years from March 2001 to Feb 2003. All patients above the age of 12 years diagnosed to be having Necrotizing Fasciitis and admitted through the Accident and emergency department were included in this study. After resuscitation, the patients underwent the emergency exploration and aggressive surgical debridement. Post-operatively, the patients were managed in isolated section of the ward. The patients requiring grafting were referred to plastic surgery unit. The patients were followed up in outpatients department for about two years. Over all, 25 male and 5 female patients fulfilled the inclusion criteria and were included in this study. The common clinical manifestations include redness, swelling, discharging abscess, pain, fever, skin necrosis and foul smelling discharge etc. The most common predisposing factor was Diabetes mellitus whereas the most commonly involved site was perineum. All patients underwent aggressive and extensive surgical debridements. The common additional procedures included Skin grafting, Secondary suturing, Cystostomy and Orchidectomy. Bacteroides and E. coli were the main micro-organisms isolated in this study. Bacteroides was the most common microorganism isolated among the eight patients who died. Necrotizing Fasciitis is a potentially life threatening emergency condition and carries the mortality rate of about 26.6%. The major contributing factors to increase the mortality missed initially diagnosed, old age, diabetes mellitus truncal involvement and late presentation. Anorectal involvement of disease carry worse prognosis. Hyperbaric oxygen therapy and proper use of unprocessed honey reduced the mortality rate. (author)

  12. Thiamine in the treatment of Wernicke encephalopathy in patients with alcohol use disorders.

    Latt, N; Dore, G

    2014-09-01

    Wernicke encephalopathy is an acute, reversible neuropsychiatric emergency due to thiamine deficiency. Urgent and adequate thiamine replacement is necessary to avoid death or progression to Korsakoff syndrome with largely irreversible brain damage. Wernicke Korsakoff syndrome refers to a condition where features of Wernicke encephalopathy are mixed with those of Korsakoff syndrome. Although thiamine is the cornerstone of treatment of Wernicke encephalopathy, there are no universally accepted guidelines with regard to its optimal dose, mode of administration, frequency of administration or duration of treatment. Currently, different dose recommendations are being made. We present recommendations for the assessment and treatment of Wernicke encephalopathy based on literature review and our clinical experience. PMID:25201422

    2013-12-01

    Full Text Available Since Hippocrates that neuropsychiatric illness secondary to liver disease fascinates physicians, but only in the XIX century Marcel Nencki and Ivan Pavlov suggested the relation between high concentrations of ammonia and Hepatic Encephalopathy (HE. The reaction of ammonia and glutamate (origins glutamine, “the Trojan Horse of neurotoxicity of ammonia continues to be the main responsible for the neurologic lesions, recently confirmed by neurochemistry and neuroimagiology studies. Glutamine starts the inflammatory reaction at the central nervous sys- tem but other important actors seem to be manganese and the neurotransmitters systems of GABA and endocanabinoids. Nowadays there are three different etiologic big groups for HE: type A associated with acute liver failure; type B associated with portosystemic bypass; and type C associated with cirrhosis of the liver. The staging of HE is still based on classic West Haven system, but a latent Grade 0 was introduced (the so called minimal HE; remaining the aggra- vating HE from Grade 1 (subtle changes at clinical examination to Grade 4 (coma. In this work a bibliographic review was made on 30 of the most pertinent and recent papers, focusing in psychopathology, physiopathology, etiology and staging of this clinical entity transversal to Psychiatry and Gastroenterology. Alterations are described in vigility and conscience like temporal, spatial and personal disorientation. Attention, concentration and memory are impaired very early, on latent phase and can be accessed through neuropsychological tests. Mood oscillates between euphoric and depressive. Personality changes begin obviously and abruptly or in a subtle and insidious way. There can be changes in perception like visual hallucinations or even of acoustic-verbal. The thought disorders can be of delusional type, paranoid, systematized or not, but also monothematic ala Capgras Syndrome. Speech can be accelerated, slowed down or completely in

    To define the therapeutic effect of Ginkgo biloba extract (EGb 761) in an experimental model of acute encephalopathy following total body irradiation in rats. Ninety four-month-old rats received 4.5 Gy total body irradiation (TBI) at day 1 while 15 rats received sham irradiation. A behavioural study based on a conditioning test of negative reinforcement, the one-way avoidance test, was performed test, was performed after irradiation. Orally treatment was started one day (study A) or twenty two days (study B) after irradiation and repeated daily for twelve days. In the irradiated group, three subgroups were defined according to the treatment received: EGb 761 (50 mg/kg), EGb 761 (100 mg/kg), water. This work comprised two consecutive studies. In study A (45 rats) the one-way avoidance test was administered daily from day 7 to day 14. In study B (45 rats) the behavioural test was performed from day 28 to day 35. Study A (three groups of 15 rats): following TBI, irradiated rats treated with water demonstrated a significant delay in a learning the one-way avoidance test in comparison with sham-irradiated rats (P < 0.0002) or irradiated rats treated with EGb 761 (50 mg/kg; P < 0.007) or EGb 761 (100 mg/kg; P < 0.0002). The irradiated rats, treated with EGb 761 (50 or 100 mg/kg) did not differ from the sham-irradiated controls. Study B (three groups of 15 rats): the irradiated rats, treated with water of EGb 761 (50 or 100 mg/kg) did not differ from the sham-irradiated controls. (authors)

Iran J Child Neurol. 2014 Winter; 8(1:1-11. Objective As acute liver failure (ALF and chronic liver disease (cirrhosis continue to increase in prevalence, we will see more cases of hepatic encephalopathy. Primary care physician are often the first to suspect it, since they are familiar with the patient’s usual physical and mental status. This serious complication typically occurs in patients with severe comorbidities and needs multidisciplinary evaluation and care. Hepatic encephalopathy should be considered in any patient with acute liver failure and cirrhosis who presents with neuropsychiatric manifestations, decrease level of consciousness (coma, change of personality, intellectual and behavioral deterioration, speech and motor dysfunction. Every cirrhotic patient may be at risk; potential precipitating factors should be addressed in regular clinic visits. The encephalopathy of liver disease may be prominent, or can be present in subtle forms, such as decline of school performance, emotional outbursts, or depression. “Subtle form” of hepatic encephalopathy may not be obvious on clinical examination, but can be detected by neurophysiologic and neuropsychiatric testing.

    Full Text Available Lead poisoning is a common occupational health hazard in developing countries. We report the varied clinical presentation, diagnostic and management issues in two adult patients with lead encephalopathy. Both patients worked in a battery manufacturing unit. Both patients presented with seizures and one patient also complained of abdominal colic and vomiting. Both were anemic and a lead line was present. Blood lead level in both the patients was greater than 25 µg/dl. Magnetic resonance imaging of brain revealed bilateral symmetric involvement of the thalamus, lentiform nucleus in both patients and also the external capsules, sub-cortical white matter in one patient. All these changes, seen as hyperintensities in T2-weighted images suggested demyelination. They were advised avoidance of further exposure to lead and were treated with anti-epileptics; one patient also received D-penicillamine. They improved well on follow-up. Lead encephalopathy is an uncommon but important manifestation of lead toxicity in adults.

Methods The male Sprague-Dawley (SD) rats were divided into three groups: ANP group(group A,n=8), ANP fish oil treatment group(group F,n=8) and control group(group C, n = 8). Five days after experiment being started, the grade of the severity of pancreatitis was evaluated by histological analysis,and the amount of food residue in the rat's gastrointestinal tract in each group were observed. Finally, the activity of serum antioxidant enzymes(SOD, GSH-Px), D-lactic acid and the concentration of serum amylase in each groups were measured respectively. Results His-topathological analysis suggested that the infiltration of the inflammatory cells in group F were significantly

  9. Necrotizing enterocolitis Enterocolitis necrosante.

    Norma Carmenate González

    Full Text Available Necrosantizing enterocolitis constitutes the most frequent and devastator gastrointestinal emergency in newborn patients, affecting especially premature patients and those with low weight (< 1500 g during the two first weeks of life, that by some motive have suffered episodes of anoxy during the labor or shortly after and in which habitually the oral diet has been initiated. It can be seen in small infants, especially in the less than 3 months and associated to diarrhea. It is reported between 15 and 75 cases by each 1000 admissions in a unit of neonatal intensive cares. The mortality varies from 10 to 40%, greater in groups of high risk and is greater than the surgical mortality of all the congenital anomalies of the digestive tract combined. We presented the Good Clinical Practices Guideline for Necrotizing enterocolitis, approved by consensus in the 2nd National Good Clinical Practices Workshop in Pediatric Surgery (Manzanillo, Cuba, September 31 - October 3, 2002.

    La enterocolitis necrosante constituye la emergencia gastrointestinal más frecuente y devastadora del recién nacido, afecta especialmente a los pretérminos y a los de bajo peso al nacer (< 1500 g durante las dos primeras semanas de vida, que por algún motivo han sufrido episodios de anoxia durante el parto o poco después y en los que habitualmente se ha iniciado la alimentación oral. Puede verse en lactantes pequeños, en especial en los menores de tres meses y asociado a cuadros de diarrea. Se reportan entre 15 y 75 casos por cada 1000 admisiones en una unidad de cuidados intensivos neonatales. La mortalidad varía de 10 a 40 %, mayor en grupos de alto riesgo y supera la mortalidad quirúrgica de todas las anomalías congénitas del tracto digestivo combinadas.

  11. Unusual tomographic findings of complicated necrotizing pancreatitis

    Rosa Maria Silveira Sigrist

    2013-12-01

    Full Text Available Acute pancreatitis (AP is a potential life-threatening disease, which originates from inflammatory involvement of the pancreas and surrounding tissues. Serious complications eventuate and treatment is difficult. AP is classified in both interstitial edematous pancreatitis, which occurs in 70-80% of patients, and necrotizing pancreatitis, which occurs in 20-30% of patients. Diagnosis is based on the presence of two of the following criteria: abdominal pain, increased serum determination of amylase and/or lipase more than three times the reference value, and characteristic tomographic findings. Among the latter, there is the pancreatic and surrounding tissue damage as well as that related to distant organ involvement. This case report shows the fatal case of a male patient with a history of heavy alcoholic abuse admitted with the diagnosis of necrotizing pancreatitis. The authors call attention to the unusual tomographic findings; namely, a huge duodenal hematoma and a large hemoperitoneum, ischemic involvement of the spleen and kidneys, as well as pancreatic and peripancreatic necrosis.

  12. [NECROTIZING FASCIITIS OF THE CHEST WALL].

    Farah, Raymond; Asla, Husam

    2016-04-01

    Necrotizing fasciitis (NF) is a bacterial dermo-hypodermitis affecting the soft tissue and muscular fascia. It is an uncommon and severe infection caused by microorganisms called 'flesh eating bacteria', mainly represented by group A beta-haemolytic streptococcus. NF remains a life-threatening condition associated with a high mortality rate. Its location on the chest wall is extremely rare. The few reported cases are subsequent to thoracic drainage, lung surgery or esophageal resection. This is a case report of an 80-year old female with comorbidity of heart disease, a past history of coronary artery by-pass and diabetes. She was admitted to the emergency room with acute NF of the chest and shortly after diagnosis, the patient died. Due to the fast decline observed in this disease, we would like to emphasize the importance of early recognition and diagnosis. PMID:27323534

  13. Massive soft tissue infections: necrotizing fasciitis and purpura fulminans.

    Edlich, Richard F; Winters, Kathryne L; Woodard, Charles R; Britt, L D; Long, William B

    2005-01-01

    Necrotizing fasciitis and purpura fulminans are two destructive infections that involve both skin and soft tissue. Necrotizing fasciitis is characterized by widespread necrosis of subcutaneous tissue and the fascia. Historically, group A beta-hemolytic streptococcus has been identified as a major cause of this infection. However, this monomicrobial infection is usually associated with some underlying cause, such as diabetes mellitus. During the last two decades, scientists have found that the pathogenesis of necrotizing fasciitis is polymicrobial. The diagnosis of necrotizing fasciitis must be made as soon as possible by examining the skin inflammatory changes. Magnetic resonance imaging is strongly recommended to detect the presence of air within the tissues. Percutaneous aspiration of the soft tissue infection followed by prompt Gram staining should be conducted with the "finger-test" and rapid-frozen section biopsy examination. Intravenous antibiotic therapy is one of the cornerstones of managing this life-threatening skin infection. Surgery is the primary treatment for necrotizing fasciitis, with early surgical fasciotomy and debridement. Following debridement, skin coverage by either Integra Dermal Regeneration Template or AlloDerm should be undertaken. Hyperbaric oxygen therapy complemented by intravenous polyspecific immunoglobulin are useful adjunctive therapies. Purpura fulminans is a rare syndrome of intravascular thrombosis and hemorrhagic infarction of the skin; it is rapidly progressive and accompanied by vascular collapse. There are three types of purpura fulminans: neonatal purpura fulminans, idiopathic or chronic purpura fulminans, and acute infectious purpura fulminans. Clinical presentation of purpura fulminans involves a premonitory illness followed by the rapid development of a septic syndrome with fever, shock, and disseminated intravascular coagulation. The diagnosis and treatment of these conditions is best accomplished in a regional burn

    Wicklund, Meredith R; Knopman, David S

    2013-08-01

    A 71-year-old woman with myelofibrosis on chemotherapy experienced an acute illness with nausea, vomiting, and diarrhea. Two weeks later, she developed an acute confusional state characterized by disorientation and fluctuating alertness with normal speech and language. Her neurologic examination demonstrated an upper motor neuron pattern of right hemiparesis. She reported double vision though ophthalmoparesis was not appreciated. Her gait was normal. While hospitalized, she developed generalized tonic-clonic seizures. Brain MRI revealed a small area of restricted diffusion of the left precentral gyrus (figure). She was diagnosed with a stroke with secondary seizures; however, as the confusional state resolved, she developed profound retrograde and anterograde amnesia. Review of the brain MRI showed high T2 signal in the medial thalamus and contrast enhancement of the mamillary bodies; a diagnosis of Wernicke-Korsakoff syndrome was entertained and she was started on thiamine replacement. The encephalopathy and hemiparesis resolved though she remains severely amnestic. PMID:24195023

    2016-09-01

    Necrotizing fasciitis of the head and neck is a rare and potentially fatal disease. It is a bacterial infection characterized by spreading along fascia planes and subcutaneous tissue resulting in tissue necrosis and likely death. It is commonly of dental or pharyngeal origin. Factors affecting the success of the treatment are early diagnosis, appropriate antibiotics and surgical debridement. Our study showed eight patients, five males and three females with mean age of 49.25 years (range 20-71 years). Clinical presentations were a rapidly progressing painful neck swelling, fever, dysphagia and trismus. The aetiology varied from idiopathic, pharyngeal/tonsillar infection, trauma and nasal malignancy. There were associated variable comorbidities (diabetes mellitus, HIV infection, hypertension and congestive cardiac failure). All the patients received early and aggressive medical treatment. The earliest time of surgery was 12 h after admission because of the poor financial status of patients. Three cases came in with complications of the disease and were not fit for extensive debridement under general anaesthesia. For them limited and reasonable bed side debridement was done. Mortality was 50 % from multiple organ failure, HIV encephalopathy, aspiration pneumonitis and septicemia. The duration of hospital stay for the patients that died ranged from 1 to 16 days and 4 to 34 days for the survivor. Our study heightens awareness and outlines the management challenges of necrotizing fasciitis of the head and neck in a poor resource setting. PMID:26626324

  18. Fatal Necrotizing Fasciitis following Episiotomy

    Faris Almarzouqi

    2015-01-01

    Full Text Available Introduction. Necrotizing fasciitis is an uncommon condition in general practice but one that provokes serious morbidity. It is characterized by widespread fascial necrosis with relative sparing of skin and underlying muscle. Herein, we report a fatal case of necrotizing fasciitis in a young healthy woman after episiotomy. Case Report. A 17-year-old primigravida underwent a vaginal delivery with mediolateral episiotomy. Necrotizing fasciitis was diagnosed on the 5th postpartum day, when the patient was referred to our tertiary care medical center. Surgical debridement was initiated together with antibiotics and followed by hyperbaric oxygen therapy. The patient died due to septic shock after 16 hours from the referral. Conclusion. Delay of diagnosis and consequently the surgical debridement were most likely the reasons for maternal death. In puerperal period, a physician must consider necrotizing fasciitis as a possible diagnosis in any local sings of infection especially when accompanied by fever and/or tenderness. Early diagnosis is the key for low mortality and morbidity.

  6. Neonatal scrotal wall necrotizing fasciitis (Fournier gangrene): a case report

    Zgraj, Oskar

    2011-12-12

    Abstract Introduction Necrotizing fasciitis in neonates is rare and is associated with almost 50% mortality. Although more than 80 cases of neonates (under one month of age) with necrotizing fasciitis have been reported in the literature, only six of them are identified as originating in the scrotum. Case presentation We report the case of a four-week-old, full-term, otherwise-healthy Caucasian baby boy who presented with an ulcerating lesion of his scrotal wall. His scrotum was explored because of a provisional diagnosis of missed torsion of the testis. He was found to have necrotizing fasciitis of the scrotum. We were able to preserve the testis and excise the necrotic tissue, and with intravenous antibiotics there was a successful outcome. Conclusions Fournier gangrene is rarely considered as part of the differential diagnosis in the clinical management of the acute scrotum. However, all doctors who care for small babies must be aware of this serious condition and, if it is suspected, should not hesitate in referring the babies to a specialist pediatric surgical center immediately.

  7. Encephalopathy for prions

    The encephalopathy spongyform for prions are neuro degenerative illness that can be sporadic or transferable, for infectious or hereditary mechanisms. Their investigation has outlined enormous challenges and in the historical journey in search of its cause two doctors have received the Nobel prize of medicine Carleton Gajdusek, for its works in New Guinea where it described the infectious transmission for cannibalistic rites that it took to studies of experimental transmission in chimpanzees and to its theory of the slow virus; later on, Stanley Prusiner developed its experimental works in hamsters, throwing to the neurobiology the prion concept (particles infectious proteinaceous not viral). The paper narrates the history of a patient that died in the San Juan de Dios of Bogota Hospital by cause of this prionic illness and clinical and pathological aspects are discussed

  8. Hepatic encephalopathy: historical remarks.

    Amodio, Piero

    2015-03-01

    The history of hepatic encephalopathy (HE) is briefly reviewed since the beginning of western medicine by Hippocrates. For about 2000 years the main evidence was the mere association between jaundice, fever and delirium. A clear link between delirium and cirrhosis was proven in the 17th century by Morgagni. In subsequent times the focus was manly the descriptions of symptoms and the only pathophysiological improvement was the evidence that jaundice, per se, does not alter brain function. Only at the end of the 19th century Hann et al proved the role of portal-systemic shunt and pf nitrogenous derivates in the pathophysiology of the syndrome. A terrific development of knowledge occurred in the last 60 years, after the works of Sherlock in London. Nowadays some consensus about HE was reached, so that new developments will likely occur.

    4 cases of acute hemorrhagic necrotic pancreatitis treated by surgery are presented in this report. While the condition is severe and its etiology remains unknown, the prognosis is fairly good in infancy provided early diagnosis is made and proper surgical treatment given. Clinical manifestation is characterized by abdominal pain, distension, vomiting and severe dehydration. Shock and peritonitis may occur in early phase. The increase in the activity of pancreatic amylase and bloody fluid obtained by abdominal puncture are of diagnostic significance.Operation is imminent once the diagnosis is established. This is especially true to younger infants. A simple operation restricted to a smaller area is advisable. We suggest manual blunt removal of the necrotic tissues. This done, the focus and the abdominal cavity should be given a rinse, followed by decompressive drainage.%@@ 成人急性出血性坏死性胰腺炎是起病急、进展快、病情重、死亡率高的严重疾病,也是猝死原因之一.虽小儿发病率较低,但病情重笃、病死率高,为危及小儿生命的一种急症.

    Paz Maya, Silvia; Dualde Beltran, Delfina [Hospital Clinico Universitario de Valencia, Valencia (Spain); Lemercier, Pierre; Leiva-Salinas, Carlos [Hospital Politecnico y Universitario La Fe, Valencia (Spain)

    2014-05-15

    Necrotizing fasciitis (NF) is a rare, life-threatening soft-tissue infection and a medical and surgical emergency, with increasing incidence in the last few years. It is characterized by a rapidly spreading, progressive necrosis of the deep fascia and subcutaneous tissue. Necrotizing fasciitis is often underestimated because of the lack of specific clinical findings in the initial stages of the disease. Many adjuncts such as laboratory findings, bedside tests - e.g., the ''finger test'' or biopsy - and imaging tests have been described as being helpful in the early recognition of the disease. Imaging is very useful to confirm the diagnosis, but also to assess the extent of the disorder, the potential surgical planning, and the detection of underlying etiologies. The presence of gas within the necrotized fasciae is characteristic, but may be lacking. The main finding is thickening of the deep fasciae due to fluid accumulation and reactive hyperemia, best seen on magnetic resonance imaging. (orig.)

    Objectives of the International Society for Hepatic Encephalopathy and Nitrogen Metabolism Commission were to identify well-characterized animal models of hepatic encephalopathy (HE) and to highlight areas of animal modelling of the disorder that are in need of development. Features essential to HE modelling were identified. The best-characterized animal models of HE in acute liver failure, the so-called Type A HE, were found to be the hepatic devascularized rat and the rat with thioacetamide-induced toxic liver injury. In case of chronic liver failure, surgical models in the rat involving end-to-side portacaval anastomosis or bile duct ligation were considered to best model minimal/mild (Type B) HE. Unfortunately, at this time, there are no satisfactory animal models of Type C HE resulting from end-stage alcoholic liver disease or viral hepatitis, the most common aetiologies encountered in patients. The commission highlighted the urgent need for such models and of improved models of HE in chronic liver failure in general as well as a need for models of post-transplant neuropsychiatric disorders. Studies of HE pathophysiology at the cellular and molecular level continue to benefit from in vitro and or ex vivo models involving brain slices or exposure of cultured cells (principally cultured astrocytes) to toxins such as ammonia, manganese and pro-inflammatory cytokines. More attention could be paid in the future to in vitro models involving the neurovascular unit, microglia and neuronal co-cultures in relation to HE pathogenesis. PMID:19638106

    Full Text Available Vijay PB Grover, Joshua M Tognarelli, Nicolas Massie, Mary ME Crossey, Nicola A Cook, Simon D Taylor-Robinson Liver Unit, Division of Diabetes, Endocrinology and Metabolism, Department of Medicine, Imperial College London, London, UK Abstract: Hepatic encephalopathy is a common neuropsychiatric abnormality, which complicates the course of patients with liver disease. It was probably first described by Hippocrates over 2000 years ago, who said that "those whose madness arises from phlegm are quiet and neither shout nor make a disturbance, while those whose madness arises from bile shout, play tricks and will not keep still, but are always up to some mischief". He was presumably describing the differences between patients with pneumonia and acute liver failure. Despite the fact that the syndrome was probably first recognized thousands of years ago, the exact pathogenesis still remains unclear. Furthermore, a precise definition of the syndrome is lacking, as are definitive methods of diagnosing this condition. It is important as both patients with cirrhosis and the general population with whom they interact may be affected as a consequence. At a minimum, the individual may be affected by impaired quality of life, impaired ability to work, and slowed reaction times, which are relevant to the population at large if affected individuals operate heavy machinery or drive a car. Pathogenic mechanisms, diagnostic tools, and treatment options are discussed. Keywords: hepatic encephalopathy, cirrhosis, ammonia, pathology, treatment, rifaximin, lactulose

    Sepsis-associated encephalopathy (SAE) is a diffuse and acute cerebral dysfunction caused by sepsis. Many sepsis patients exhibit acute deterioration in mental status during the early stage of disease, and central nervous system dysfunction has been shown to increase patient mortality. The present study selected 284 sepsis patients who were admitted to the Intensive Care Unit of Beijing Friendship Hospital, Capital Medical University, from January to December 2009. The patients were assigned to SAE and non-SAE patient groups according to SAE occurrence. SAE incidence was 37.68%, and mortality was significantly greater in SAE patients compared with non-SAE patients (41.12% vs. 17.51%, P < 0.01). Univariate analysis and multivariate logistic regression analysis indicated lower arterial partial pressure of oxygen and greater alanine aminotransferase and Acute Physiology and Chronic Health Evaluation II scores in the SAE group compared with the non-SAE group. Arterial partial pressure of oxygen, alanine aminotransferase, and Acute Physiology and Chronic Health Evaluation II scores were determined to be potential risk factors for SAE.

    Full Text Available Objective. Encephalopathy and brain edema are serious complications of acute liver injury and may lead to rapid death of patients. The present study was designed to investigate the role of the inflammatory mediators and oxidative stress in the cytotoxic brain oedema and the neuroprotective effects of both minocycline and dexamethasone. Methods. 48 male albino rats were divided into 4 groups: control group, acute liver injury (ALI group, minocycline pretreated ALI group, and dexamethasone pretreated ALI group. 24 hours after acute liver injury serum ammonia, liver enzymes, brain levels of heme oxygenase-1 gene, iNOS gene expression, nitrite/nitrate, and cytokines were measured. In addition, the grades of encephalopathy and brain water content were assessed. Results. ALI was associated with significant increases in all measured inflammatory mediators, oxidative stress, iNOS gene expression, and nitrite/nitrate. Both minocycline and dexamethasone significantly modulated the inflammatory changes and the oxidative/nitrosative stress associated with ALI. However, only minocycline but not dexamethasone significantly reduced the cytotoxic brain oedema. Conclusion. Both minocycline and dexamethasone could modulate inflammatory and oxidative changes observed in brain after ALI and could be novel preventative therapy for hepatic encephalopathy episodes.

    Korsakoff syndrome is a chronic form of amnesia resulting from thiamine deficiency. The syndrome can develop from unrecognized or undertreated Wernicke encephalopathy. The intra-individual course of Wernicke-Korsakoff syndrome has not been studied extensively, nor has the temporal progression of gait disturbances and other symptoms of Wernicke encephalopathy. Here we present the detailed history of a patient whose acute symptoms of Wernicke encephalopathy were far from stable. We follow his mobility changes and the shifts in his mental status from global confusion and impaired consciousness to more selective cognitive deficits. His Wernicke encephalopathy was missed and left untreated, being labeled as "probable" Korsakoff syndrome. Patients with a history of self-neglect and alcohol abuse, at risk of or suffering with Wernicke encephalopathy, should receive immediate and adequate vitamin replacement. Self-neglecting alcoholics who are bedridden may have severe illness and probably active Wernicke encephalopathy. In these patients, mobility changes, delirium, or impaired consciousness can be an expression of Wernicke encephalopathy, and should be treated to prevent further damage from the neurologic complications of thiamine deficiency.

    Septic encephalopathy represents the most frequently observed form of encephalopathy in intensive care units. Interactions between the immune and nervous systems have been observed in experimental sepsis. Therefore, the aim of the current study was to characterize the effect of different severities of sepsis on encephalopathy and the inflammatory profile of the spleen. We hypothesized that different grades of sepsis severity would lead to variations in encephalopathy and activation of spleen cells. We induced sepsis of different severities in Balb/c mice by cecal ligature and puncture (CLP). Six and 12 h after CLP induction, behavioral impairment was assessed by the SmithKline/Harwell/Imperial College/Royal Hospital/Phenotype Assessment (SHIRPA) test. The animals were then killed, and the plasma, spleen, and hippocampus were removed. Levels of the encephalopathy marker S100β were measured in plasma. Spleens were weighed and then a characterization of splenic lymphocytes was performed by flow cytometry (cytotoxic T lymphocyte, T helper lymphocytes, B lymphocytes, T regulatory cells, and Th17 cells). Cytokine levels in the spleen and hippocampus were determined by enzyme-linked immunosorbent assay (ELISA), and cytokine levels in plasma were performed with MilliPlex® technology. Our results showed that behavioral impairment as measured by the SHIRPA test and elevation in plasma S100β levels were significant in moderate and severe CLP groups compared to those in the sham control group. Regarding immunological alterations, we were unable to observe changes in the weights of the spleen and the profile of lymphocytes 6 h after CLP. However, several cytokines, including IL-6, IL-10, and IL-1β, were increased in spleen and plasma. In conclusion, we observed variations in encephalopathy as measured by plasma S100β, which were mediated by the severity of sepsis; however, we did not observe a different activation of spleen cells 6 h post-CLP, despite evidence of

  9. Approach to clinical syndrome of jaundice and encephalopathy in tropics.

    Anand, Anil C; Garg, Hitendra K

    A large number of patients present with jaundice and encephalopathy in tropical country like India and acute liver failure is the usual cause. Clinical presentation like ALF is also a complication of many tropical infections, and these conditions may mimic ALF but may have subtle differences from ALF. Moreover, what hepatologists see as acute liver failure in tropics is different from what is commonly described in Western Textbooks. Paracetamol overdose, which is possibly the commonest cause of ALF in UK and USA, is hardly ever seen in India. Most common etiology here is viral hepatitis (hepatitis E > hepatitis B> hepatitis A). Apart from ALF, one may also come across subacute hepatic failure (SAHF) as well as acute-on-chronic liver failure (ACLF) due to viral hepatitis. Interestingly, a host of other conditions can mimic ALF because clinical presentation in these conditions can be dominated by jaundice and encephalopathy. Malarial hepatopathy is possibly the best-known condition out of these and is not an uncommon manifestation of severe malaria. A similar presentation can also be seen in other common infections in tropics such as dengue fever, typhoid fever, leptospirosis, scrub typhus, amoebic liver abscesses, tuberculosis and other bacterial and fungal infections with or without human immunodeficiency virus (HIV) related disease. In many of these conditions, liver failure may not be underlying pathophysiology. Some pregnancy related liver diseases could also present with jaundice and encephalopathy. This review summarizes the commonly seen presentations in tropical country like India, where jaundice and encephalopathy dominate the clinical picture. PMID:26041951

    BACKGROUND: Patients with hepatic encephalopathy may present with extrapyramidal symptoms and changes in basal ganglia. These changes are similar to those seen in patients with Parkinson's disease. Dopamine agents (such as bromocriptine and levodopa, used for patients with Parkinson's disease) have...... therefore been assessed as a potential treatment for patients with hepatic encephalopathy. OBJECTIVES: To evaluate the beneficial and harmful effects of dopamine agents versus placebo or no intervention for patients with hepatic encephalopathy. SEARCH METHODS: Trials were identified through the Cochrane...... the trials followed participants after the end of treatment. Only one trial reported adequate bias control; the remaining four trials were considered to have high risk of bias. Random-effects model meta-analyses showed that dopamine agents had no beneficial or detrimental effect on hepatic...
