    The decision to operate for abdominal pain in patients with leukopenia can be exceedingly difficult. Surgical exploration may be the only effective way to differentiate acute appendicitis from other causes, but it involves considerable risk of infectious complications due to immunesuppression. Leukemic patients, who presented significant RLQ pain, had been indicated for operation, despite having advanced disease or having had received chemotherapy or steroids. Four adult leukemia patients, complicated by acute appendictis, were reviewed. Two patients were in induction chemotherapy, one receiving salvage chemotheapy due to relapse and the other was in conservative treatment. Two patients were acute myelocytic leukemia (AML), one had acute lymphocytic leukemia (ALL), and the other had aleukemic leukemia. All patients underwent appendectomy and recovered without complication. Our experience supports the theory that the surgical management of appendicitis in acute leukemia is the most effective way, in spite of leukopenia. PMID:8268146

    Introduction Balapiravir (R1626, RG1626) is the prodrug of a nucleoside analogue inhibitor of the hepatitis C virus (HCV) RNA-dependent RNA polymerase (R1479, RG1479). This phase 2, double-blind international trial evaluated the optimal treatment regimen of balapiravir plus peginterferon alfa-2a (40KD)/ribavirin. Material and methods Treatment-naive genotype 1 patients (N = 516) were randomized to one of seven treatment groups in which they received balapiravir 500, 1,000, or 1,500 mg twice daily, peginterferon alfa-2a (40KD) 180 or 90 μg/week and ribavirin 1,000/1,200 mg/day or peginterferon alfa-2a (40KD)/ribavirin. The planned treatment duration with balapiravir was reduced from 24 to 12 weeks due to safety concerns. Results The percentage of patients with undetectable HCV RNA was consistently higher in all balapiravir groups from week 2 to 12. However, high rates of dose modifications and discontinuations of one/all study drugs compromised the efficacy assessment and resulted in similar sustained virological response rates in the balapiravir groups (range 32-50%) and the peginterferon alfa-2a (40KD)/ribavirin group (43%). Balapiravir was discontinued for safety reasons in 28-36% of patients (most often for lymphopenia) and the percentage of patients with serious adverse events (especially hematological, infection, ocular events) was dose related. Serious hematological adverse events (particularly neutropenia, lymphopenia) were more common in balapiravir recipients. Two deaths in the balapiravir/peginterferon alfa-2a/ribavirin combination groups were considered possibly related to study medication. Conclusion Further development of balapiravir for the treatment of chronic hepatitis C has been halted because of the unacceptable benefit to risk ratio revealed in this study (www.ClinicalTrials.gov NCT 00517439).

    Acute bloody diarrhoea may be commonly encountered in the acute medical unit. Among young patients, the main differential diagnoses are acute infectious colitis, and first presentation of inflammatory bowel disease (IBD). A combination of clinical, laboratory, radiological, endoscopic and histological investigations are required to make the diagnosis. If inflammatory bowel disease is suspected, then the patient should be admitted to a specialist gastroenterology ward and receive input from the surgical team, IBD nurses and specialist stoma nurses. Intravenous steroid therapy for acute severe disease should be started before stool cultures are back unless there is a strong clinical suspicion of amoebiasis. All patients require thromboprophylaxis and close attention paid to fluid balance and nutritional requirements. Daily clinical review is required. The Travis criteria may be employed at day 3 to assess the likelihood of requiring surgery and plans for rescue therapy, medical or surgical should be made between day 3-7 if the patient is not responding adequately to initial medical therapy.

    We reviewed 50 patients admitted to the department of Otorhinolaryngology and Head & Neck Surgery of Govt Medical College Srinagar from September 19% to September 2002 diagnosed with acute epiglottitis. Male were more commonly involved than females in the ratio of 2.8:1 with only 6 cases younger than 10 years of age. The highest incidence was in the month of January (22%). The common symptoms of acute epiglottitis were sorethroat(92%) and odynophagia(88%). Any patient with sudden onset of these symptoms should be suspected of having acute epiglottitis and should have an indirect laryngoscopy. Blood culture was obtained in 20 cases Cultures were positive only in 5 cases, out of which 4 were positive for Hemophilus influenzae type B. Throat cultures were not obtamed The primary treatment of acute epiglottitis is intravenous antibiotics, steriods, and humidified air. Treacheostomy was needed only in 4 patients. There were no deaths.

    Planning for patient discharge is an essential element of any admission to an acute setting, but may often be left until the patient is almost ready to leave hospital. This article emphasises why discharge planning is important and lists the essential principles that should be addressed to ensure that patients leave at an optimum time, feeling confident and safe to do so. Early assessment, early planning and co-ordination of all the teams involved in the patient's care are essential. Effective communication between the various teams and with the patient and their family or carer(s) is necessary. Patients should leave hospital with all the information, medications and equipment they require. Appropriate plans should have been developed and communicated to the receiving community or non-acute team. When patient discharge is effective, complications as a result of extended lengths of hospital stay are prevented, hospital beds are used efficiently and readmissions are reduced.

    Ursodeoxycholic acid (UDCA) is a hydrophilic bile acid that possesses many pharmacological effects, including increasing bile flow, changing the hydrophobicity of the bile acid pool, and modulation of the immune response. UDCA has been approved for treating cholestatic liver disease, such as primary biliary cholangitis. However, several unanticipated severe side effects of UDCA are observed in cholestatic patients, and its pharmacological benefits remain controversial. We reported that ezrin-knockdown (Vil2(kd/kd)) mice exhibited severe hepatic injury because of a functional disorder in bile duct fluidity and alkalinity regulation, resembling human intrahepatic cholestatic disease. Here we used Vil2(kd/kd) mice as a cholestatic model to investigate the pharmacological effects of UDCA. We investigated the effects of oral and parenteral administration of UDCA on Vil2(kd/kd) mice. In Vil2(kd/kd) mice, fed a 0.5% (w/w) UDCA diet for 3 weeks, hepatic injury was exacerbated, although oral administration of a lower dose of UDCA slightly improved hepatic function in Vil2(kd/kd) mice. On the other hand, intraperitoneal administration of UDCA (50 mg/kg/d) ameliorated hepatic function and markedly reduced periductal fibrosis and cholangiocyte proliferation in Vil2(kd/kd) mice although biliary pH and HCO3(-) concentration were not improved. The expression levels of inflammatory and profibrotic genes were also significantly decreased in these mice. Furthermore, UDCA prevented cholangiocytes from hydrophobic bile acid-induced cytotoxicity independent of extracellular pH in in vitro experiments. These results suggest that an appropriate dosage of UDCA can ameliorate the intrahepatic cholestasis in Vil2(kd/kd) mice without changing the biliary bicarbonate secretion.

    Kimura disease (KD) is an immune-mediated chronic inflammatory disease of unknown etiology. KD has many complications associated with hypereosinophilia, including various forms of allergic reactions and eosinophilic lung disease. Additionally, hypereosinophilia is associated with hypercoagulability, which may lead to thromboembolic events. A 36-year-old man with KD presented with acute limb ischemia and coronary artery occlusion. He underwent thrombectomy, partial endarterectomy of both popliteal arteries, and coronary artery stent insertion. KD is a systemic disease that affects many organs and presents with thromboembolism and vasculitis. In a patient with KD, physicians should evaluate the vascular system, including the coronary arteries. PMID:28382271

    Acute kidney injury (AKI) is a frequent and significant complication of cancer and cancer therapy. Cancer patients frequently encounter risk factors for AKI including older age, CKD, prerenal conditions, sepsis, exposure to nephrotoxins, and obstructive physiology. AKI can also be secondary to paraneoplastic conditions, including glomerulonephritis and microangiopathic processes. This complication can have significant consequences, including effects on patients' ability to continue to receive therapy for their malignancy. This review will serve to summarize potential etiologies of AKI that present in patients with cancer as well as to highlight specific patient populations, such as the critically ill cancer patient.

    No well-defined Blastomyces-specific antigens are currently available. We used sodium dodecyl sulfate-polyacrylamide gel electrophoresis and immunoblotting to identify immunologically active molecules in the cell wall of B. dermatitidis. A major immunoreactive 120-kD protein (WI-1) was present in all five strains studied and comprised 5% of the protein in the cell wall extract obtained after freezing and thawing yeast cells. WI-1 was recognized by serum from all 10 patients with blastomycosis but by none of those from 5 patients with histoplasmosis. It was purified by electroelution, radiolabeled with 125I, and incorporated into a radioimmunoassay (RIA) for serodiagnosis of blastomycosis. Antibody to WI-1 was detected in 58 (85%) of 68 patients with blastomycosis (geometric mean titer, 1:2,981), in two (3%) of 73 patients with histoplasmosis, coccidioidomycosis, sporotrichosis, or candidiasis (titers, 1:86 and 1:91) and in none of 44 healthy persons. WI-1 was shown to be a surface molecule abundant on B. dermatitidis yeasts that were indirectly stained with serum from a rabbit immunized with WI-1. Approximately 0.93 pg of WI-1 or 4.7 x 10(6) WI-1 molecules were found on the surface of an individual yeast using an antigen-inhibition RIA; none was found on Histoplasma capsulatum or Candida albicans yeasts. We conclude that WI-1 is a novel, immunologically active surface molecule on the invasive form of B. dermatitidis and that WI-1 can be used to reliably detect antibody and study the immunopathogenesis of blastomycosis.

    Hepatitis C virus (HCV) infection is frequent in patients with end-stage renal disease treated by chronic dialysis, with a prevalence varying from 10-65% according to the geographical data. The prevalence is significantly associated with the duration of dialysis and the number of transfused blood products[1,2] and has dramatically declined with efficient blood screening.[3] We studied patients with acute HCV infection in a dialysis unit. The diagnosis was based on both anti-HCV detection and HCV-RNA detection. Other virological tools including HCV genotype determination was also used to tailor treatment to the individual patient and determine its efficacy for a one-year follow-up period. Seventeen patients (7 male and 10 female, mean age: 63.7 +/- 11.6 SD) with acute hepatitis C were enrolled to our study. All of them were followed up for a period of one year after the diagnosis was established. Phylogenetic analysis distinguished two separate HCV subtypes 1b, which were both responsible for this acute infection (see Figure 1). These types did not differ in their behavior on the clinical situation of our patients, as confirmed by the fact that in both groups of patients, there was only one patient who presented with acute illness. Six patients of our study group, three months after the acute infection, received pegylated interferon (Peg-IFNa2a) 135 mug for a six-month period. Four of them responded very well to therapy and at the first determination HCV RNA was below the cutoff point. One of our patients with very high HCV levels (HCV RNA > 50,000,000 IU/mL), despite receiving the same therapy, did not respond well and developed cirrhosis. In conclusion, it is clear from our experience that better information is needed about the current incidence, prevalence, and risk factors for HCV infection in dialysis patients. Algorithms for the diagnosis and management of hepatitis C should be developed by academic societies. Routine screening for hepatitis C also would allow

    Stroke is a major cause of death and disability. Anesthesiologists are likely to encounter patients with stroke and must be aware of the anesthetic considerations for these patients. Intravenous thrombolysis and intra-arterial thrombolysis are effective treatments for acuteischemic stroke as well as evolving endovascular techniques such as mechanical clot retrieval. Recent retrospective studies have found an association between general anesthesia and poor clinical outcome. The results of these studies have several limitations, and current evidence is inadequate to guide the choice of anesthesia in patients with acute stroke. The choice of anesthesia must be based on individual patient factors until further research is completed.

  13. Serum level of soluble 70-kD heat shock protein is associated with high mortality in patients with colorectal cancer without distant metastasis

    Many findings indicate that measuring the serum concentration of soluble 70-kD heat shock protein (soluble HSP70) may provide important information in cardiovascular, inflammatory, and pregnancy-related diseases; however, only scarce data are available in cancer. Therefore, using a commercial ELISA kit, we measured soluble HSP70 concentration in the sera of 179 patients with colorectal cancer. We investigated the relationship between soluble HSP70 concentration and mortality, during 33.0 (24.4–44.0) months long follow-up. High (>1.65 pg/ml, median concentration) soluble HSP70 level was a significant (hazard ratio: 1.88 (1.20–2.96, p = 0.005) predictor of mortality during the follow-up period. When we compared the soluble HSP70 levels in patients with non-resected primary tumors as compared to those who were recruited into the study 4–6 weeks after the tumor resection they were found to be significantly (p = 0.020) higher in the former group. Since the patients with non-resected primary tumors had also distant metastasis and died early, we limited the further analysis to 142 patients with no distant metastasis at the beginning of the follow-up. This association remained significant even after multiple Cox-regression analysis had been performed to adjust the data for age and sex (p = 0.028); age, sex, and TNM-T stage (p = 0.041); age, sex, and TNM-N stage (p = 0.021); age, sex, and histological grade (p = 0.023); or age, sex, and tumor localization (p = 0.029). Further analysis showed that the significant association between high HSP70 levels and poor survival is in the strongest in the group of <70-year-old female patients (HR: 5.52 (2.02-15.15), p = 0.001), as well as in those who were in a less advanced stage of the disease at baseline. These novel findings indicate that the serum level of soluble HSP70 might prove a useful, stage-independent prognostic marker in colorectal cancer without distant metastasis. PMID:19578980

    Acute kidney injury (AKI) occurs commonly in patients with advanced cirrhosis and negatively impacts pre- and post-transplant outcomes. Physiologic changes that occur in patients with decompensated cirrhosis with ascites, place these patients at high risk of AKI. The most common causes of AKI in cirrhosis include prerenal injury, acute tubular necrosis (ATN), and the hepatorenal syndrome (HRS), accounting for more than 80% of AKI in this population. Distinguishing between these causes is particularly important for prognostication and treatment. Treatment of Type 1 HRS with vasoconstrictors and albumin improves short term survival and renal function in some patients while awaiting liver transplantation. Patients with HRS who fail to respond to medical therapy or those with severe renal failure of other etiology may require renal replacement therapy. Simultaneous liver kidney transplant (SLK) is needed in many of these patients to improve their post-transplant outcomes. However, the criteria to select patients who would benefit from SLK transplantation are based on consensus and lack strong evidence to support them. In this regard, novel serum and/or urinary biomarkers such as neutrophil gelatinase-associated lipocalin, interleukins-6 and 18, kidney injury molecule-1, fatty acid binding protein, and endothelin-1 are emerging with a potential for accurately differentiating common causes of AKI. Prospective studies are needed on the use of these biomarkers to predict accurately renal function recovery after liver transplantation alone in order to optimize personalized use of SLK.

    Coronary artery (CA) abnormalities influence exercise capacity (EC) of patients with Kawasaki disease (KD), and Z-score of CA is a well established method for detecting CA aneurysm. We studied the influence of KD on cardiopulmonary function and EC; meanwhile we analyzed echocardiographic findings of KD patients. We also assessed the correlation between CA Z-score and EC of KD patients to see if CA Z-score of KD patients could reflect EC during exercise.Sixty-three KD patients were recruited as KD group 1 from children (aged 5-18 y) who received transthoracic echocardiographic examinations and symptom-limited treadmill exercise test for regular follow-up of KD from January 2010 to October 2014 in 1 medical center. We then divided KD group 1 into KD group 2 (<5 y, n = 12) and KD group 3 (≥5 y, n = 51) according to time interval between KD onset to when patients received test. Control groups were matched by age, sex, and body mass index. Max-Z of CA was defined as the maximal Z-score of the proximal LCA or RCA by Dalliarre equation or Fuse calculator.All routine parameters measured during standard exercise test were similar between KD and control groups, except that peak rate pressure products (PRPPs) in KD group 1 to 3 were all lower than corresponding control groups significantly (P = 0.010, 0.020, and 0.049, respectively). PRPPs correlated with Max-Z of CA by both equations modest inversely (by Dallaire, P = 0.017, Spearman rho = -0.301; by Fuse, P = 0.014, Spearman rho = -0.309).Our study recruited larger number of KD patients and provided a newer data of EC of KD patients. Our finding suggests that after acute stage of KD, patients could maintain normal cardiorespiratory fitness. Therefore, we believe that it is important to promote cardiovascular health to KD patients and KD patients should exercise as normal peers. However, since KD patients might still have compromised coronary perfusion during exercise, it remains crucial to

    A random sample of those admitted to acute psychiatric wards in Sheffield in 1985 was traced to establish whether or not the patients were homeless 5 years later. Contrary to expectations none were found to be homeless. Although the proportion of mentally ill amongst the homeless may be significantly high, the number discharged from psychiatric hospital, at least in Sheffield, living consistently 'on the streets' or staying regularly in night shelters seems small as a proportion of all discharges.

    Acute kidney injury (AKI) is costly and is associated with increased mortality and morbidity. An understanding of the renal physiologic changes that occur during pregnancy is essential for proper evaluation, diagnosis, and management of AKI. As in the general population, AKI can occur from prerenal, intrinsic, and post-renal causes. Major causes of pre-renal azotemia include hyperemesis gravidarum and uterine hemorrhage in the setting of placental abruption. Intrinsic etiologies include infections from acute pyelonephritis and septic abortion, bilateral cortical necrosis, and acute tubular necrosis. Particular attention should be paid to specific conditions that lead to AKI during the second and third trimesters, such as preeclampsia, HELLP syndrome, acute fatty liver of pregnancy, and TTP-HUS. For each of these disorders, delivery of the fetus is the recommended therapeutic option, with additional therapies indicated for each specific disease entity. An understanding of the various etiologies of AKI in the pregnant patient is key to the appropriate clinical management, prevention of adverse maternal outcomes, and safe delivery of the fetus. In pregnant women with pre-existing kidney disease, the degree of renal dysfunction is the major determining factor of pregnancy outcomes, which may further be complicated by a prior history of hypertension.

    2017-01-01

    Highly active antiretroviral treatment (HAART) has considerably increased the life expectancy of patients infected with HIV. Coronary artery disease is a leading cause of mortality in patients infected with HIV. This is primarily attributed to their increased survival, HAART-induced metabolic derangements, and to HIV itself. The pathophysiology of atherosclerosis in HIV is both multifactorial and complex – involving direct endothelial injury and dysfunction, hypercoagulability, and a significant contribution from traditional cardiac risk factors. The advent of HAART has since heralded a remarkable improvement in outcomes, but at the expense of other unforeseen issues. It is thus of paramount importance to swiftly recognize and manage acute coronary syndromes in HIV-infected patients to attenuate adverse complications, which should translate into improved clinical outcomes.

    1981-08-01

    To define the role of ultrasound in evaluating acute right upper quadrant pain, a prospective study was performed on 52 patients having clinically suspected acute cholecystitis. Ultrasonographic determination of acute or chronic cholecystitis, or diagnosis of a normal gallbladder, was based on analysis of location of tenderness, calculi, sludge, and wall thickness. The diagnosis of acute cholecystitis (34.6% of patients) was based on the highly significant observations of focal gallbladder tenderness and calculi. Sludge and wall thickening were also statistically significant, but to a lesser degree. Cholelithiasis allowed differentiation of patients with chronic cholecystitis (32.7%) from patients with normal gallbladders (32.7%). Neither of these two groups had significant focal gallbladder tenderness, sludge, or thickened walls. Because acute cholecystitis is found in the minority of patients with acute right upper quadrant pain, and because ultrasound is rapid, accurate, and noninvasive, it should be the initial modality used to evaluate these patients.

    Stroke is a devastating event that carries a potential for long-term disability. Malnutrition is frequently observed in patients with stroke, and dysphagia contributes to malnutrition risk. During both the acute phase of stroke and rehabilitation, specific nutritional interventions in the context of a multidisciplinary team effort can enhance the recovery of neurocognitive function. Early identification and management of malnutrition with dietary modifications or specific therapeutic strategies to ensure adequate nutritional intake should receive more attention, since poor nutritional status appears to exacerbate brain damage and to contribute to adverse outcome. The main purpose of nutritional intervention should be the prevention or treatment of complications resulting from energy-protein deficit. This paper reviews the evaluation and management of malnutrition and the use of specialized nutrition support in patients with stroke. Emphasis is given to enteral tube and oral feeding and to strategies to wean from tube feeding. PMID:22254136

    Acute urinary retention (AUR) is more than ten times more common in men than women. In men it tends to occur in the elderly; the risk of AUR is higher in men > 70 years. The causes in men can be divided into precipitated or occurring spontaneously. These can be further divided according to the mechanism i.e. obstructive, neurological and myogenic. Spontaneous AUR, caused by progression of BPH leading to a mechanical obstruction of the bladder outlet, is the most common cause of AUR. The typical presentation of AUR is a patient complaining of a sudden inability to urinate associated with progressive abdominal distension which is usually painful. The pain increases in intensity with increasing distension of the bladder. An abdominal examination should reveal a distended bladder which can be confirmed by a dull percussion note. A digital rectal examination is vital to gain information on prostatic enlargement (benign or malignant), faecal load in rectum, anal tone and presence of other masses. Urinalysis and culture should be carried out on a sample obtained after catheterisation to rule out infection. Renal function should be assessed to see if there has been damage to the upper tracts. It is better not to perform a PSA test in this situation as it will invariably be raised due to distension of the bladder and catheter insertion. If catheter insertion fails then a urological consultation is required for insertion of a suprapubic catheter. Admission is essential if the patient is: unwell with urosepsis; has abnormal renal function needing investigation and fluid monitoring; has acute neurological problems; or cannot take care of the catheter. Trial without catheter needs to be planned and the ideal time to do this is within 2-3 days so that the patient can pass urine naturally.

    Abstract Acute pancreatitis (AP) is a rare manifestation of pancreatic cancer (PC). The relationship between AP and PC remains less distinct. From January 2009 to November 2015, 47consecutive patients with PC who presented with AP were reviewed for this study. Clinical features, clinicopathologic variables, postoperative complications, and follow-up evaluations of patients were documented in detail from our database. In order to identify cutoff threshold time for surgery, receiver operating curve (ROC) was built according to patients with or without postoperative complications. Cumulative rate of survival was calculated by using the Kaplan–Meier method. The study was conducted in accordance with the principles of the Declaration of Helsinki and the guidelines of West China Hospital. This study included 35 men (74.5%) and 12 women (25.5%) (mean age: 52 years), with a median follow-up of 40 months. AP was clinically mild in 45 (95.7%) and severe in 2 (4.3%). The diagnosis of PC was delayed by 2 to 660 days (median 101 days). Thirty-nine (83.0%) cases underwent surgery. Eight (17.0%) cases performed biopsies only. Of 39 patients, radical surgery was performed in 32 (82.1%) cases and palliative in 7 (19.9%) cases. Two (8.0%) patients were needed for vascular resection and reconstruction. Postoperative complications occurred in 12 (30.8%) patients. About 24.5 days was the best cutoff point, with an area under curve (AUC) of 0.727 (P = 0.025, 95% confidence interval: 0.555–0.8999). The survival rate of patients at 1 year was 23.4%. The median survival in patients with vascular resection and reconstruction was 18 months, compared with 10 months in patients without vascular resection (P = 0.042). For the primary stage (T), Tix was identified in 3 patients, the survival of whom were 5, 28, 50 months, respectively. And 2 of them were still alive at the follow-up period. The severity of AP was mainly mild. Surgical intervention after 24.5 days may benefit for

    Periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis syndrome (PFAPA) is one of the autoinflammatory diseases of unknown etiology characterized by regularly recurrent fever episodes with attacks lasting 3-6 days every 3-8 weeks associated with at least one of the three cardinal clinical signs: aphthous stomatitis, pharyngitis, and cervical adenitis. Kawasaki disease (KD) is an acute, self-limited systemic vasculitis that occurs predominantly in infants and young children. In most KD patients, i.v. immunoglobulin leads to a rapid amelioration of clinical symptoms and significantly decreases the risk of coronary artery aneurysms. Although the etiology of KD is still unknown, it was reported that innate immunity was activated in the patients. Described herein is a patient with PFAPA who developed KD. This is the first report of KD development in a PFAPA patient. The association between KD and PFAPA may represent a genetic predisposition to dysregulated innate immune response.

    Neurologic disorders, mainly Guillain-Barré syndrome and Parsonage–Turner syndrome (PTS), have been described in patients with hepatitis E virus (HEV) infection in industrialized and developing countries. We report a wider range of neurologic disorders in nonimmunocompromised patients with acute HEV infection. Data from 15 French immunocompetent patients with acute HEV infection and neurologic disorders were retrospectively recorded from January 2006 through June 2013. The disorders could be divided into 4 main entities: mononeuritis multiplex, PTS, meningoradiculitis, and acute demyelinating neuropathy. HEV infection was treated with ribavirin in 3 patients (for PTS or mononeuritis multiplex). One patient was treated with corticosteroids (for mononeuropathy multiplex), and 5 others received intravenous immunoglobulin (for PTS, meningoradiculitis, Guillain-Barré syndrome, or Miller Fisher syndrome). We conclude that pleiotropic neurologic disorders are seen in HEV-infected immunocompetent patients. Patients with acute neurologic manifestations and aminotransferase abnormalities should be screened for HEV infection. PMID:26490255

    Mixed phenotype acute leukemia (MPAL) includes biphenotypic and bilineal types of leukemia, which constitute rare subtypes that require individualized therapy. Outcomes in Moroccan patients with MPAL are unknown. Among 1264 patients with acute leukemia, 20 were classified as having MPAL, including 17 with biphenotypic acute leukemia (1.3%) and 3 with bilineal leukemia (0.2%). There were 8 adults and 12 children. In 12 cases (60%), leukemic blasts expressed myeloid and T-lymphoid antigens, and, in 5 cases (25%), leukemic blasts expressed B lymphoid antigens plus myeloid antigens. Patients were initially treated on protocols for acute myeloid leukemia (n=4), acute lymphoblastic leukemia (ALL, n=14), or with palliative care (n=2). The probability of survival at 2 years in MPAL cases was 52%± 14%. Six of the 12 patients younger than 15 years remain alive versus 1 of 8 adult patients. Patients treated with ALL-directed therapy had significantly higher overall survival than those treated with acute myeloid leukemia-directed therapy (P=0.003). There was no association between the phenotypic characteristics and the clinical outcome (P=0.83). In conclusion, MPAL represents 1.5% of acute leukemia in Morocco. The prognosis is poor, but initial treatment with therapy directed toward ALL, improved supportive care, and the prevention of abandonment of therapy may improve outcomes in this subgroup of patients.

    Definition of Respiratory Failure using PaO2 alone is confounded when patients are commenced on oxygen therapy prior to arterial blood gas (ABG) measurement. Furthermore, classification of Respiratory Failure as Type 1 or Type 2 using PaCO2 alone can give an inaccurate account of events as both types can co-exist. 100 consecutive presentations of acute respiratory distress were assessed initially using PaO2, and subsequently PaO2/FiO2 ratio, to diagnose Respiratory Failure. Respiratory Failure cases were classified as Type 1 or Type 2 initially using PaCO2, and subsequently alveolar-arterial (A-a) gradient. Any resultant change in management was documented. Of 100 presentations, an additional 16 cases were diagnosed as Respiratory Failure using PaO2/FiO2 ratio in place of PaO2 alone (p = 0.0338). Of 57 cases of Respiratory Failure, 22 cases classified as Type 2 using PaCO2 alone were reclassified as Type 1 using A-a gradient (p < 0.001). Of these 22 cases, management changed in 18.

    Malaria is one of the most common protozoan diseases, especially in tropical countries. The clinical manifestation of malaria, especially falciparum malaria varies from mild acute febrile illness to life threatening severe systemic complications involving one or more organ systems. We would like to report a case of complicated falciparum malaria involving cerebral, renal, hepatic system along with acute pancreatitis. The patient was successfully treated with anti malarial and other supportive treatment. To the best of our knowledge there are very few reports of acute pancreatitis due to malaria. Falciparum malaria therefore should be added to the list of infectious agents causing acute pancreatitis especially in areas where malaria is endemic.

    Loss of protective airway reflexes in patients with acute coma puts these patients at risk of aspiration pneumonia complicating the course of the primary disease. Available data vary considerably with regard to bacteriology, role of anaerobic bacteria, and antibiotic treatment. Our objective was to research the bacteriology of aspiration pneumonia in acute coma patients who were not pre-treated with antibiotics or hospitalized within 30 days prior to the event. We prospectively analyzed 127 patient records from adult patients admitted, intubated and ventilated to a tertiary medical intensive care unit with acute coma. Bacteriology and antibiotic resistance testing from tracheal aspirate sampled within 24 h after admission, blood cultures, ICU scores (APACHE II, SOFA), hematology, and clinical chemistry were assessed. Patients were followed up until death or hospital discharge. The majority of patients with acute coma suffered from acute cardiovascular disorders, predominantly myocardial infarction, followed by poisonings, and coma of unknown cause. In a majority of our patients, microaspiration resulted in overt infection. Most frequently S. aureus, H. influenzae, and S. pneumoniae were isolated. Anaerobic bacteria (Bacteroides spec., Fusobacteria, Prevotella spec.) were isolated from tracheal aspirate in a minority of patients, and predominantly as part of a mixed infection. Antibiotic monotherapy with a 2nd generation cephalosporin, or a 3rd generation gyrase inhibitor, was most effective in our patients regardless of the presence of anaerobic bacteria.

    Background: Acute cholecystitis is the major complication of biliary lithiasis, for which laparoscopic treatment has been established as the standard therapy. With longer life expectancy, acute cholecystitis has often been seen in elderly patients (>65 years old) and is often accompanied by comorbity and severe complications. We sought to compare the outcome of laparoscopic treatment for acute cholecystitis with special focus on comparison between elderly and nonelderly patients. Method: This study was a prospective analysis of 190 patients who underwent laparoscopic cholecystectomy due to acute cholecystitis or chronic acute cholecystitis, comparing elderly and nonelderly patients. Results: Of 190 patients, 39 (21%) were elderly (>65 years old) and 151 (79%) were not elderly (≤65 years), with conversion rates of 10.3% and 6.6% (P=0.49), respectively. The incidence of postoperative complications in elderly and nonelderly patients were the following, respectively: atelectasis 5.1% and 2.0% (P=0.27); respiratory infection 5.1% and 2.7% (P=0.6); bile leakage 5.1% and 2.0% (P=0.27), and intraabdominal abscess 1 case (0.7%) and no incidence (P=1). Conclusion: According to our data, laparoscopic cholecystectomy is a safe and efficient procedure for the treatment of acute cholecystitis in patients older than 65 years of age. PMID:17575761

    Delirium is an acute medical emergency affecting about one in eight acute hospital inpatients. It is associated with poor outcomes, is more prevalent in older people and it is estimated that half of all patients receiving intensive care or surgery for a hip fracture will be affected. Despite its prevalence and impact, delirium is not reliably identified or well managed. Improving the identification and management of patients with delirium has been a focus for the national improving older people's acute care work programme in NHS Scotland. A delirium toolkit has been developed, which includes the 4AT rapid assessment test, information for patients and carers and a care bundle for managing delirium based on existing guidance. This toolkit has been tested and implemented by teams from a range of acute care settings to support improvements in the identification and immediate management of delirium.

    Sickle cell disease is a chronic hematologic disease with a variety of acute, and often recurring, complications. Vaso-occlusive crisis, a unique but common presentation in sickle cell disease, can be challenging to manage. Acute chest syndrome is the leading cause of death in patients with sickle cell disease, occurring in more than half of patients who are hospitalized with a vaso-occlusive crisis. Uncommon diagnoses in children, such as stroke, priapism, and transient red cell aplasia, occur more frequently in patients with sickle cell disease and necessitate a degree of familiarity with the disease process and its management. Patients with sickle cell trait generally have a benign course, but are also subject to serious complications. This issue provides a current review of evidence-based management of the most common acute complications of sickle cell disease seen in pediatric patients in the emergency department.

    This is the first report of a case of seminal vesiculitis prior to acute chlamydial epididymitis. At the first visit to the clinic, the patient wished to check whether he had Chlamydia trachomatis in his genital tract, because his wife had been diagnosed as having chlamydial cervicitis. He had no specific symptoms at that time; however, transrectal ultrasonograpy (TRUS) revealed swelling of seminal vesicles, which suggested the presence of seminal vesiculitis. Two days after the first visit, he had high-grade fever and was diagnosed as having acute epididymitis caused by C. trachomatis. We had previously reported that seminal vesiculitis was always complicated with acute epididymitis, so this case could provide important evidence that seminal vesiculitis might precede acute epididymitis. It suggested that acute epididymitis could be affected by seminal vesiculitis via the retrograde transmission route.

    Ischemic heart disease is the leading cause of mortality worldwide. Due to advances in medicine in the past few decades, life expectancy has increased resulting in an aging population in developed and developing countries. Acute coronary syndrome causes greater morbidity and mortality in this group of older patients, which appears to be due to age-related comorbidities. This review examines the incidence and prevalence of acute coronary syndrome among older patients, examines current treatment strategies, and evaluates the predictors of adverse outcomes. In particular, the impact of frailty on outcomes and the need for frailty assessment in developing future research and management strategies among older patients are discussed.

    2016-03-01

    The proportion of diabetic patients who are hospitalised for stroke has been increasing in recent years, currently reaching almost a third of all cases of stroke. In addition, about half of patients with acute stroke present hyperglycaemia in the first hours of the stroke. Although hyperglycaemia in the acute phase of stroke is associated with a poor prognosis, its treatment is currently a topic of debate. There is no evidence that the adminstration of intravenous insulin to these patients offers benefits in terms of the evolution of the stroke. New studies in development, such as the SHINE study (Stroke Hyperglycemia Insulin Network Effort), may contribute to clarifying the role of intensive control of glycaemia during the acute phase of the stroke. Ultimately, patients who have presented with stroke should be screened for diabetes.

    Pharmacokinetics of methohexital were studied in patients with acute hepatitis and after a treatment period either with "essential phospholipids" or phenobarbital. During the acute phase the distribution of methohexital was significantly altered. No change had been observed in the methohexital clearance. During remission the distribution of methohexital was in a normal range. After treatment with phenobarbital the methohexital clearance increased significantly whereas no change was observed after treatment with "essential phospholipids".

    The influence of pneumonia in acute stroke stage on the clinical presentation and long-term outcomes of patients with acute ischemic stroke is still controversial. We investigate the influence of pneumonia in acute stroke stage on the 3-year outcomes of patients with acute first-ever ischemic stroke. Nine-hundred and thirty-four patients with acute first-ever ischemic stroke were enrolled and had been followed for 3years. Patients were divided into two groups according to whether pneumonia occurred during acute stroke stage or not. Clinical presentations, risk factors for stroke, laboratory data, co-morbidities, and outcomes were recorded. The result showed that a total of 100 patients (10.7%) had pneumonia in acute stroke stage. The prevalence of older age, atrial fibrillation was significantly higher in patients with pneumonia in acute stroke stage. Total anterior circulation syndrome and posterior circulation syndrome occurred more frequently among patients with pneumonia in acute stroke stage (P<0.001 and P=0.009, respectively). Multivariate Cox regression revealed that pneumonia in acute stroke stage is a significant predictor of 3-year mortality (hazard ratio=6.39, 95% confidence interval=4.03-10.11, P<0.001). In conclusion, pneumonia during the acute stroke stage is associated with increased risk of 3-year mortality. Interventions to prevent pneumonia in acute stroke stage might improve ischemic stroke outcome.

    Cholelithiasis is the most common cause of acute pancreatitis, accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned, the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management, including cholecystectomy, endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy, or no definitive treatment. Delaying cholecystectomy until after resolution of the inflammatory process, usually not earlier than 6 wk after onset of acute pancreatitis, seems to be a safe policy. ERCP and sphincterotomy on index admission prevent recurrent episodes of pancreatitis until cholecystectomy is performed, but if used for definitive treatment, they can be a valuable tool for patients unfit for surgery. Some patients who survive severe biliary pancreatitis may develop pseudocysts or walled-off necrosis. Management of pseudocysts with minimally invasive techniques, if not therapeutic, can be used as a bridge to definitive operative treatment, which includes delayed cholecystectomy and concurrent pseudocyst drainage in some patients. A management algorithm has been developed for patients surviving severe biliary pancreatitis according to the currently published data in the literature. PMID:27678352

    Ultrasonography was performed as the first imaging procedure in 100 patients who presented with acute right upper quadrant pain suggestive of cholecystitis or cholelithiasis. In the final analysis 46 patients were found to have gallbladder disease (40 patients with cholelithiasis, 5 with acalculous cholecystitis, and 1 with a cholesterol polyp in the gallbladder). In 22 of 54 patients with a normal gallbladder, other abdominal disease was found. The error rate for ultrasound was 5%, and in 4 patients ultrasound was not the suitable procedure for the diagnosis. In 91 patients the ultrasonographic diagnosis was correct.

    Respiratory viruses (RVs) are ubiquitous pathogens that represent a major cause of community-acquired pneumonia and chronic pulmonary diseases exacerbations. However, their contribution to acute respiratory failure events requiring intensive care unit admission in the era of rapid multiplex molecular assay deserves further evaluation. This study investigated the burden of viral infections in non immunocompromised patients admitted to the intensive care unit for acute respiratory failure using a multiplex molecular assay. Patients were investigated for RVs using immunofluoresence testing and a commercial multiplex molecular assay, and for bacteria using conventional culture. Half the patients (34/70, 49%) had a documented RVs infection. No other pathogen was found in 24 (71%) patients. Viral infection was detected more frequently in patients with obstructive respiratory diseases (64% vs. 29%; P = 0.0075). Multiplex molecular assay should be considered as an usefull diagnostic tool in patients admitted to the intensive care unit with acute respiratory failure, especially those with acute exacerbations of chronic obstructive pulmonary disease and asthma.

    Hyperlactataemia is commonly used as a diagnostic and prognostic tool in intensive care settings. Recent studies documented that serial lactate measurements over time (or lactate clearance), may be clinically more reliable than lactate absolute value for risk stratification in different pathological conditions. While the negative prognostic role of hyperlactataemia in several critical ill diseases (such as sepsis and trauma) is well established, data in patients with acute cardiac conditions (i.e. acute coronary syndromes) are scarce and controversial. The present paper provides an overview of the current available evidence on the clinical role of lactic acid levels and lactate clearance in acute cardiac settings (acute coronary syndromes, cardiogenic shock, cardiac surgery), focusing on its prognostic role.

    To test the hypothesis that a mobilization of endothelial progenitor cells (EPCs) occurs after acute cerebrovascular diseases, we evaluated the number of EPCs in the process of acute stroke. A total of 203 individuals were examined, including 100 patients with ischemic strokes, 36 patients with hemorrhagic strokes and 67 healthy controls. Ninety-eight patients were observed at days 1, 7, 14 and 28 after acute stroke. Circulating EPCs were defined by the surface markers CD133/KDR and analyzed by flow cytometry. Serum high sensitivity C-reactive protein (hs-CRP) concentrations were determined by particle-enhanced immunonephelometry using the N high sensitivity CRP Reagent. Patients with acute stroke had lower numbers of EPCs (0.037+/-0.001/100 peripheral blood mononuclear cells (PMNCs) vs. 0.06+/-0.002/100 PMNCs, P<0.05) and higher levels of serum hs-CRP (1.99 vs. 0.03 mg per 100 ml, P<0.05) than control subjects after adjusting for age, sex, body mass index (BMI) and blood pressure. There were no differences in EPCs counts or serum hs-CRP levels between patients with ischemic and hemorrhagic stroke. In univariate analyses, BMI, age, systolic blood pressure (SBP), diastolic blood pressure, low-density lipoprotein (LDL), total cholesterol (T-cho), blood glucose and hs-CRP (P<0.001) were inversely correlated with EPCs counts. Multivariate analyses showed SBP and total cholesterol as independent predictors of EPCs levels. The number of EPCs gradually increased at day 7 after acute onset, remained elevated at day 14; and returned to baseline by day 28. Our results suggest a possible contribution of circulating EPCs in acute stroke. SBP and total cholesterol are independent factors of reduced EPCs numbers. A transient early increment of EPCs may result from the mobilization of EPCs in response to stroke stress.

    Acute Lyme disease results from transmission of and infection by the bacterium Borrelia burgdorferi following a tick bite. During acute infection, bacteria can disseminate to the central nervous system (CNS) leading to the development of Lyme meningitis. Here we have analyzed pooled cerebrospinal fluid (CSF) allowing for a deep view into the proteome for a cohort of patients with early-disseminated Lyme disease and CSF inflammation leading to the identification of proteins that reflect host responses, which are distinct for subjects with acute Lyme disease. Additionally, we analyzed individual patient samples and quantified changes in protein abundance employing label-free quantitative mass spectrometry based methods. The measured changes in protein abundances reflect the impact of acute Lyme disease on the CNS as presented in CSF. We have identified 89 proteins that differ significantly in abundance in patients with acute Lyme disease. A number of the differentially abundant proteins have been found to be localized to brain synapse and thus constitute important leads for better understanding of the neurological consequence of disseminated Lyme disease.

    Objectives Myocardial infarction (MI) may be experienced as a traumatic event causing acute stress disorder (ASD). This mental disorder has an impact on the daily life of patients and is associated with the development of post-traumatic stress disorder. Trait resilience has been shown to be a protective factor for post-traumatic stress disorder, but its association with ASD in patients with MI is elusive and was examined in this study. Methods We investigated 71 consecutive patients with acute MI within 48 h of having stable haemodynamic conditions established and for 3 months thereafter. All patients completed the Acute Stress Disorder Scale and the Resilience Scale to self-rate the severity of ASD symptoms and trait resilience, respectively. Results Hierarchical regression analysis showed that greater resilience was associated with lower symptoms of ASD independent of covariates (b=−0.22, p<0.05). Post hoc analysis revealed resilience level to be inversely associated with the ASD symptom clusters of re-experiencing (b=−0.05, p<0.05) and arousal (b=−0.09, p<0.05), but not with dissociation and avoidance. Conclusions The findings suggest that patients with acute MI with higher trait resilience experience relatively fewer symptoms of ASD during MI. Resilience was particularly associated with re-experiencing and arousal symptoms. Our findings contribute to a better understanding of resilience as a potentially important correlate of ASD in the context of traumatic situations such as acute MI. These results emphasise the importance of identifying patients with low resilience in medical settings and to offer them adequate support. PMID:26568834

    Various rhythm and conduction abnormalities can develop in acute rheumatic fever. This study investigated rhythm and conduction abnormalities in children with acute rheumatic fever using a standard 12-lead electrocardiogram and 24-h rhythm Holter recordings. This multicenter retrospective study, performed between August 2011 and March 2012, enrolled 73 consecutive children with acute rheumatic fever. Standard electrocardiography was used to measure PR and corrected QT intervals. Holter recordings were evaluated for all the patients, and 52 of the patients (71.2 %) had carditis that was either isolated or together with other major criteria. A positive correlation was detected between carditis and the mean PR interval on standard electrocardiography, but this was not significant (p > 0.05). Standard electrocardiography showed a significant positive correlation between PR and corrected QT intervals (p = 0.03; r = 0.55). Standard electrocardiography showed only three patients (4.2 %) with premature contractions, whereas 24-h electrocardiography showed 26 patients (35.6 %) with premature contractions. Carditis was positively correlated with premature contractions (p < 0.01; r = 0.57). One patient with junctional rhythm and one patient with left bundle block were detected by standard electrocardiography. Whereas some patients with carditis exhibited no arrhythmic evidence on standard electrocardiograms, complete atrioventricular block, supraventricular tachycardia, and Mobitz type 1 block were observed on 24-h Holter recordings. A positive correlation also was observed between the presence of premature contractions and serum levels of acute-phase reactants (p = 0.03; r = 0.62). These findings led to the conclusion that rhythm and conduction disorders in acute rheumatic fever are more common than previously thought.

    Each year, 1·0–2·0% of individuals with atrial fibrillation and 0·1–0·2% of those with venous thromboembolism who are receiving one of the novel oral anticoagulants (dabigatran, rivaroxaban, or apixaban) can be expected to experience an acute ischemic stroke. Additionally, 0·2–0·5% of individuals with atrial fibrillation who are receiving one of the novel oral anticoagulants can be expected to experience an intracranial hemorrhage. This opinion piece addresses the current literature and offers practical approaches to the management of patients receiving novel oral anticoagulants who present with an ischemic or hemorrhagic stroke. Specifically, we discuss the role of thrombolysis in anticoagulated patients with acute ischemic stroke and factors to consider concerning restarting anticoagulation after acute ischemic and hemorrhagic stroke.

    Although cardiac infiltration is common in advanced stage of acute leukaemia, it is not usually diagnosed at life and it is extremely rare for it to become pseudotumoral. A 25-years-old patient with an acute monoblastic leukaemia who had a leukaemic infiltration which affected the main part of the left ventricle at the time of diagnosis, is referred. The heart infiltration was detected by a two dimension echocardiography. In spite of a massive infiltration, heart failure was not present and the left ventricle's ejection fraction was 50%. Even though chemotherapy was administered, the patient died four days after diagnosis due to septic shock of respiratory origin. The most relevant autopsy finding was a widespread pseudotumoral infiltration of the left ventricle, the back side of the right ventricle and the interventricular wall. The pseudotumoral infiltration of the heart by acute leukaemia is uncommon and must be differentiated from granulocytic sarcoma. The usefulness of the different diagnostic procedures is discussed.

In this article we are trying to analize the reasons and to emphasize the need to include this subject in our Nursing Problem List. In it we explaine the fears and the wrong ideas that we have identified in our patients. The sexual function is not affected by a myocardial infarction but psychological factors, age, drugs and other associated diseases might be a reason. A quiet enviroment, a fit training plan and looking for personalise proper alternatives may help the patient to start a satisfactory sexual life again.

    During acute Lyme disease, bacteria can disseminate to the central nervous system (CNS) leading to the development of meningitis and other neurologic symptoms. Here we have analyzed pooled cerebrospinal fluid (CSF) allowing a deep view into the proteome for patients diagnosed with early-disseminated Lyme disease and CSF inflammation. Additionally, we analyzed individual patient samples and quantified differences in protein abundance employing label-free quantitative mass spectrometry based methods. We identified 108 proteins that differ significantly in abundance in patients with acute Lyme disease from controls. Comparison between infected patients and control subjects revealed differences in proteins in the CSF associated with cell death localized to brain synapses and others that likely originate from brain parenchyma.

    OBJECTIVES: Acute respiratory failure is present in 5% of patients with acute myocardial infarction and is responsible for 20% to 30% of the fatal post-acute myocardial infarction. The role of inflammation associated with pulmonary edema as a cause of acute respiratory failure post-acute myocardial infarction remains to be determined. We aimed to describe the demographics, etiologic data and histological pulmonary findings obtained through autopsies of patients who died during the period from 1990 to 2008 due to acute respiratory failure with no diagnosis of acute myocardial infarction during life. METHODS: This study considers 4,223 autopsies of patients who died of acute respiratory failure that was not preceded by any particular diagnosis while they were alive. The diagnosis of acute myocardial infarction was given in 218 (4.63%) patients. The age, sex and major associated diseases were recorded for each patient. Pulmonary histopathology was categorized as follows: diffuse alveolar damage, pulmonary edema, alveolar hemorrhage and lymphoplasmacytic interstitial pneumonia. The odds ratio of acute myocardial infarction associated with specific histopathology was determined by logistic regression. RESULTS: In total, 147 men were included in the study. The mean age at the time of death was 64 years. Pulmonary histopathology revealed pulmonary edema as well as the presence of diffuse alveolar damage in 72.9% of patients. Bacterial bronchopneumonia was present in 11.9% of patients, systemic arterial hypertension in 10.1% and dilated cardiomyopathy in 6.9%. A multivariate analysis demonstrated a significant positive association between acute myocardial infarction with diffuse alveolar damage and pulmonary edema. CONCLUSIONS: For the first time, we demonstrated that in autopsies of patients with acute respiratory failure as the cause of death, 5% were diagnosed with acute myocardial infarction. Pulmonary histology revealed a significant inflammatory response, which has

    Magnetic resonance (MR) imaging of the patient with acute cervical injury is important because of the potential prognostic significance of the appearance of the spinal cord at the time of injury. However, cervical traction may involve equipment incompatible with the magnetic environment, and transferring the patient to the imaging table may make it difficult to maintain traction. The authors describe a simple, inexpensive, and reliable method for providing cervical traction within the magnet room.

    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

    Objective To define the role of gastrointestinal (GI) decontamination of the poisoned patient. Data Sources A computer-based PubMed/MEDLINE search of the literature on GI decontamination in the poisoned patient with cross referencing of sources. Study Selection and Data Extraction Clinical, animal and in vitro studies were reviewed for clinical relevance to GI decontamination of the poisoned patient. Data Synthesis The literature suggests that previously, widely used, aggressive approaches including the use of ipecac syrup, gastric lavage, and cathartics are now rarely recommended. Whole bowel irrigation is still often recommended for slow-release drugs, metals, and patients who "pack" or "stuff" foreign bodies filled with drugs of abuse, but with little quality data to support it. Activated charcoal (AC), single or multiple doses, was also a previous mainstay of GI decontamination, but the utility of AC is now recognized to be limited and more time dependent than previously practiced. These recommendations have resulted in several treatment guidelines that are mostly based on retrospective analysis, animal studies or small case series, and rarely based on randomized clinical trials. Conclusions The current literature supports limited use of GI decontamination of the poisoned patient. PMID:21992527

    Asthma is a chronic inflammatory disease of the airways. The global prevalence of asthma ranges from 1% to 18% of the population, so it remains a common problem with enormous medical and economic impacts. In majority of patients, asthma can be well controlled with simple regimens of inhaled anti-inflammatory and bronchodilating medications. However, some patients tend to suffer from poorly controlled disease in terms of chronic symptoms with episodic severe exacerbations. Major factors that may be related to the emergency department visits and hospitalisation include prior severe attacks, nonadherence to therapeutic regimens, inadequate use of inhaled corticosteroids, poor self-management skills, frequent use of inhaled short-acting beta-agonists, cigarette smoking, poor socioeconomic status and age over 40 years. Severe exacerbations of asthma are life-threatening medical emergencies and require careful brief assesment, treatment according to current GINA (Global Initiative for Asthma) guidelines with periodic reassesment of patient's response to therapy usually in an emergency department.

    Objective: Gerstmann in 1924. observed in a few patients a concomitant impairment in discriminating their own fingers, writing by hand, distinguishing left from right and performing calculations. He claimed that this tetrad of symptoms constituted a syndromal entity, assigned it to a lesion of the dominant parietal lobe. Since than, Gerstmann`s syndrome (GS) was enigma for neuropsychologists. The aim of this study was to analyze frequency and clinical features of GS among acute stroke patients. Patients and methods: We prospectively analyzed 194 acute stroke patients (average age 65±11.06 years, male 113 (58.2%), female 81 (41.8%) hospitalized at department of Neurology, University Clinical Center tuzla, during the six mounths in 2010. For clinical assessment of agraphia, alexia and acalculia we used Minessota test for differential diagnosis of aphasia’s. Results: Among these acute stroke patients, 59 (30.40%) had alexia, agraphia and acalculia or different combinations of these disorders. two patients (3.4%) had agraphia and acalculia associated with other part of tetrad of GS: fi nger agnosia and left-right disorientation. they both where men, right handed, and cranial computed tomography scan showed ischemic lesion in the left parietal and left temporoparietal lobe. Conclusion: Gerstmann`s syndrome is rare clinical entity, and has the high value in localization and the lesion is mainly localized to angular gyrus of the dominant hemisphere. PMID:23378691

    Background Hospital admission for the treatment of acute decompensated heart failure is an unfortunate certainty in the vast majority of patients with heart failure. Regardless of the etiology, inpatient treatment for acute decompensated heart failure portends a worsening prognosis. Methods This review identifies patients with heart failure who need inpatient therapy and provides an overview of recommended therapies and management of these patients in the hospital setting. Results Inpatient therapy for patients with acute decompensated heart failure should be directed at decongestion and symptom improvement. Clinicians should also treat possible precipitating events, identify comorbid conditions that may exacerbate heart failure, evaluate and update current guideline-directed medical therapy, and perform risk stratification for all patients. Finally, efforts should be made to educate patients about the importance of restricting salt and fluid, monitoring daily weights, and adhering to a graded exercise program. Conclusion Early discharge follow-up and continued optimization of guideline-directed medical therapy are key to preventing future heart failure readmissions. PMID:26413005

    Kawasaki disease (KD) is an acute febrile illness of early childhood. Previous reports have suggested that genetic disease susceptibility factors, together with a triggering infectious agent, could be involved in KD pathogenesis; however, the precise etiology of this disease remains unknown. Additionally, previous culture-based studies have suggested a possible role of intestinal microbiota in KD pathogenesis. In this study, we performed metagenomic analysis to comprehensively assess the longitudinal variation in the intestinal microbiota of 28 KD patients. Several notable bacterial genera were commonly extracted during the acute phase, whereas a relative increase in the number of Ruminococcus bacteria was observed during the non-acute phase of KD. The metagenomic analysis results based on bacterial species classification suggested that the number of sequencing reads with similarity to five Streptococcus spp. (S. pneumonia, pseudopneumoniae, oralis, gordonii, and sanguinis), in addition to patient-derived Streptococcus isolates, markedly increased during the acute phase in most patients. Streptococci include a variety of pathogenic bacteria and probiotic bacteria that promote human health; therefore, this further species discrimination could comprehensively illuminate the KD-associated microbiota. The findings of this study suggest that KD-related Streptococci might be involved in the pathogenesis of this disease. PMID:26322033

  9. Delirium in acute promyelocytic leukemia patients: two case reports

    PubMed Central

    2013-01-01

    Background Delirium is a frequently misdiagnosed and inadequately treated neuropsychiatric complication most commonly observed in terminally ill cancer patients. To our knowledge this is the first report describing delirium in two patients aged less than 60 years and enrolled in an intensive chemotherapeutic protocol for acute promyelocytic leukemia. Case presentation Two female Caucasian acute promyelocytic leukemia patients aged 46 and 56 years developed delirium during their induction treatment with all-trans retinoic acid and idarubicin. In both cases symptoms were initially attributed to all-trans retinoic acid that was therefore immediately suspended. In these two patients several situations may have contribute to the delirium: in patient 1 a previous psychiatric disorder, concomitant treatments with steroids and benzodiazepines, a severe infection and central nervous system bleeding while in patient 2 steroid treatment and isolation. In patient 1 delirium was treated with short-term low-doses of haloperidol while in patient 2 non-pharmacologic interventions had a beneficial role. When the diagnosis of delirium was clear, induction treatment was resumed and both patients completed their therapeutic program without any relapse of the psychiatric symptoms. Both patients are alive and in complete remission as far as their leukemia is concerned. Conclusions We suggest that patients with acute promyelocytic leukemia eligible to intensive chemotherapy should be carefully evaluated by a multisciplinary team including psychiatrists in order to early recognize symptoms of delirium and avoid inadequate treatments. In case of delirium, both pharmacologic and non-pharmacologic interventions may be considered. PMID:24237998

    Background Acute pancreatitis is an inflammatory disease of the pancreas due to enzymatic autodigestion which can cause necrosis or multiple organ failure; its pathophysiology is not fully known yet. Aim To evaluate the correlation between clinical and therapeutic data in patients with mild acute pancreatitis. Methods A retrospective study in 55 medical records of patients admitted with acute mild pancreatitis was realized to analyze the association between age, leukocytosis, serum glutamic-oxaloacetic transaminase and lactate dehydrogenase, glucose, antibiotics, time admission and Ranson´s scores. Results There was a positive association between less intensive care (strict hydration, analgesia and monitoring of vital signs), early antibiotic therapy (monotherapy), early return to diet after 48 hours and laboratory control of the serum amylase and lipase (high in the first week and decreasing after 10 days, without any prognostic value). Conclusions Changes in the management of patients with mild acute pancreatitis, such as enteral nutrition, rational use of lower spectrum antibiotics and intensive care, have contributed significantly to the reduction of hospitalization time and mortality.

    The case of an 87-year-old woman who falls at home and is admitted to the Emergency Department of an acute hospital with delirium exemplify a common situation that physicians face in their everyday clinical practice. We describe the typical context of frailty in which acute illnesses frequently present in frail elderly patients and, in particular, the relationship between comorbidity, disability and frailty. We also report the current knowledge about frailty theories and we focus on the "atypical" presentation of many acute illnesses. Major attention is devoted on delirium and on mobility impairment, two of the most common atypical symptoms of elderly frail subjects. Finally we describe the evidence on the comprehensive geriatric assessment, i.e., the method that is required to identify and understand the ultimate needs of elderly complex subjects.

    Pleural effusions are rarely observed in patients with acute myelogenous leukemia (AML), acute lymphocytic leukemia (ALL) and myelodysplastic syndrome (MDS)/myeloproliferative neoplasm (MPN). Therefore the underlying etiology of pleural effusions and the efficacy and safety of pleural procedures in this population has not been well studied. In a retrospective review of cases from 1997 to 2007, we identified 111 patients with acute leukemia or MDS/MPN who underwent pleural procedures. Clinical characteristics were reviewed, and survival outcomes were estimated by Kaplan-Meier methods. A total of 270 pleural procedures were performed in 111 patients (69 AML, 27 ALL, 15 MDS/MPN). The main indications for pleural procedures were possible infection (49%) and respiratory symptoms (48%), and concomitant clinical symptoms included fever (34%), dyspnea (74%), chest pain (24%) and cough (37%). Most patients had active disease (61%). The most frequent etiology of pleural effusions was infection (47%), followed by malignancy (36%). Severe thrombocytopenia (platelet count < 20 × 10(3)/µL) was present in 43% of the procedures, yet the procedural complication rate was only 1.9%. Multivariate analysis revealed that older age, AML, MDS/MPN and active disease status were associated with a shorter median overall survival. Infection and malignant involvement are the most common causes of pleural effusion in patients with acute leukemia or MDS. After optimizing platelet count and coagulopathy, thoracentesis may be performed safely and with high diagnostic yield in this population. Survival in these patients is determined by the response to treatment of the hematologic malignancy.

    Objective Lateral brain displacement has been associated with loss of consciousness and poor outcome in a range of acute neurologic disorders. We studied the association between lateral brain displacement and awakening from acute coma. Methods This prospective observational study included all new onset coma patients admitted to the Neurosciences Critical Care Unit (NCCU) over 12 consecutive months. Head computed tomography (CT) scans were analyzed independently at coma onset, after awakening, and at follow-up. Primary outcome measure was awakening, defined as the ability to follow commands before hospital discharge. Secondary outcome measures were discharge Glasgow Coma Scale (GCS), modified Rankin Scale, Glasgow Outcome Scale, and hospital and NCCU lengths of stay. Results Of the 85 patients studied, the mean age was 58 ± 16 years, 51% were female, and 78% had cerebrovascular etiology of coma. Fifty-one percent of patients had midline shift on head CT at coma onset and 43 (51%) patients awakened. In a multivariate analysis, independent predictors of awakening were younger age (odds ratio [OR] = 1.039, 95% confidence interval [CI] = 1.002–1.079, p = 0.040), higher GCS score at coma onset (OR = 1.455, 95% CI = 1.157–1.831, p = 0.001), nontraumatic coma etiology (OR = 4.464, 95% CI = 1.011–19.608, p = 0.048), lesser pineal shift on follow-up CT (OR = 1.316, 95% CI = 1.073–1.615, p = 0.009), and reduction or no increase in pineal shift on follow-up CT (OR = 11.628, 95% CI = 2.207–62.500, p = 0.004). Interpretation Reversal and/or limitation of lateral brain displacement are associated with acute awakening in comatose patients. These findings suggest objective parameters to guide prognosis and treatment in patients with acute onset of coma. PMID:25628166

    Kawasaki disease (KD) is a self-limited, systemic vasculitis of children for which an infectious trigger is suspected. Recently, an association between KD and human coronavirus (HCoV)-New Haven (NH) was reported, on the basis of polymerase chain reaction (PCR) with primers that also amplified HCoV-NL63. We investigated the possible association between these HCoVs in the respiratory tract and KD by reverse-transcriptase (RT) PCR and viral culture in a geographically and ethnically diverse population. Only 1 (2%) of 48 patients with acute KD was positive by RT-PCR for HCoV-NL63/NH in a nasopharyngeal swab. These data do not support an association between these HCoVs and KD.

    Protein and calorie malnutrition have been encountered more frequently than expected in the hemodialysis patients. Intradialytic parenteral nutrition (IDPN) has been documented to improve nutritional status in hemodialysis patients in both acute and chronic settings (Henrich, 1996). The aim of this study was to support the usage of IDPN in our malnourished hemodialysis patients. Serum concentration of albumin is one of the main indicators of mortality in the dialysis population. The serum albumin concentration for six out of eight of our hemodialysis (HD) patients receiving IDPN increased significantly. There was a mean increase of 7.0 g/L of plasma albumin for the eight patients assessed. These results demonstrate that IDPN is an effective nutritional intervention for malnourished hemodialysis patients.

    We investigated the effect of octreotide in the treatment of severe acute pancreatitis in a case-control study. Experimental and clinical studies on the effect of octreotide in the treatment of acute pancreatitis have shown controversial results. Since January 1992, we have been conducting a prospective randomized study on the effect of octreotide in severe acute pancreatitis, in three hospitals in Israel. The entering criteria included three or more of the Ranson prognostic signs and CT findings of severe pancreatitis. Patients were randomly assigned to conservative treatment either with or without octreotide (0.1 mg subcutaneously three times a day). The end points of the study included: complication rate (ARDS, sepsis, renal failure, pseudocyst, fistula, and abscess), length of hospital stay, and mortality. From January 1992 to December 1996, 60 patients entered the study. After evaluating the files, 10 patients were excluded due to failure to meet the entering criteria, incomplete data, or incorrect diagnosis. Of the remaining 50 patients, 25 were assigned to octreotide (treatment group) and 25 to conservative treatment only (control group). The two groups matched with regard to age, sex, etiology, and severity of the disease. The complication rate was lower in the treatment group with regard to sepsis (24% vs 76%, P = 0.0002) and ARDS (28% vs 56%, P = 0.04). The hospital stay was shorter in the treatment group (20.6 vs 33.1 days, P = 0.04). Two patients died in the treatment group and eight in the control group (P < 0.019). These results suggest that octreotide may have a beneficial effect in the treatment of severe acute pancreatitis.

    Antifungal prophylaxis is routinely given to patients with hematologic malignancies at high risk for invasive fungal infections (IFI), yet breakthrough IFI may still occur. Posaconazole emerged as an excellent alternative for fungal prophylaxis in high-risk patients. There is limited data about pharmacokinetics and plasma concentrations of posaconazole when given as prophylaxis in patients with hematologic malignancies. We recruited 20 adult patients for prospective, open label trial of posaconazole given as a prophylaxis in patients with newly diagnosed acute myeloid leukemia (AML) undergoing induction chemotherapy or first salvage therapy. The median age of all patients was 65 years and received prophylaxis for a median of 38 days (range: 5-42 days).Ten patients (50%) completed 42 days on posaconazole prophylaxis. Median plasma posaconazole levels showed no statistical difference across gender, body surface area, patients developing IFI, and patients acquiring grade 3 or 4 elevation of liver enzymes. However, there was an overall trend for higher trough concentrations among patients with no IFI than those with IFI. Pharmacokinetics of posaconazole varies from patient to patient, and AML patients receiving induction chemotherapy who never develop IFI tend to have higher plasma concentrations after oral administration of posaconazole.

    The interrelation between kidney disease and cancer is complex and reciprocal. Among the most frequent cancer-associated kidney diseases are the electrolyte and acid-base disturbances, which occur frequently and often are associated with an ominous prognosis, and acute kidney injury. Tumor lysis syndrome is a potentially life-threatening condition that frequently occurs in patients with a high tumor burden and high cellular turnover after cytotoxic therapy (including steroids in steroid-sensitive hematologic malignancies). Electrolyte and acid-base disturbances are the consequence of neoplastic spread, anticancer treatment, or, more rarely, paraneoplastic phenomena of all types of tumors. This article reviews hyponatremia and hypernatremia, hypokalemia and hyperkalemia, hypomagnesemia, hypercalcemia and hypocalcemia, hypophosphatemia, and the most important disturbances in acid-base balance in cancer patients. Acute kidney injury (AKI) is a frequent occurrence in cancer patients and has the potential to substantially alter the outcome of patients with cancer and jeopardize their chances of receiving optimal cancer treatment and a potential cure. As in many other circumstances, the etiology of AKI in cancer patients is multifactorial. Initiation and/or continuation of dialysis in the AKI cancer patient should be based on the general clinical condition and overall life expectancy and the personal patient expectations on quality of life after eventual recovery.

    Acute appendicitis is a common cause for pediatric surgery, with an increasing incidence as this population ages. Pseudomembranous colitis (PMC) from Clostridum difficle is being seen more frequently in pediatric patients, especially after treatment with antibiotics and in those with Hirschsprung's disease. Only three prior cases of appendicitis associated with PMC have been described in the literature, and all of them occurred in adult patients. Here, we describe the first documented pediatric case: a 16-year-old female who developed acute appendicitis while concomitantly being treated for suspected pseudomembranous colitis. We concur with previous authors that there may be an association between these two pathologies; furthermore, this association may not always be clinically apparent and may be both under-diagnosed and under-reported.

    Background Previous studies have described an “obesity paradox” with heart failure, whereby higher body mass index (BMI) is associated with lower mortality. However, little is known about the impact of obesity on survival after acute myocardial infarction. Methods Data from 2 registries of patients hospitalized in the United States with acute myocardial infarction between 2003–04 (PREMIER) and 2005–08 (TRIUMPH) were used to examine the association of BMI with mortality. Patients (n=6359) were categorized into BMI groups (kg/m2) using baseline measurements. Two sets of analyses were performed using Cox proportional hazards regression with fractional polynomials to model BMI as categorical and continuous variables. To assess the independent association of BMI with mortality, analyses were repeated adjusting for 7 domains of patient and clinical characteristics. Results Median BMI was 28.6. BMI was inversely associated with crude 1-year mortality (normal, 9.2%; overweight, 6.1%; obese, 4.7%; morbidly obese; 4.6%; p<0.001), which persisted after multivariable adjustment. When BMI was examined as a continuous variable, the hazards curve declined with increasing BMI and then increased above a BMI of 40. Compared with patients with a BMI of 18.5, patients with higher BMIs had a 20% to 68% lower mortality at 1 year. No interactions between age (p=0.37), gender (p=0.87) or diabetes mellitus (p=0.55) were observed. Conclusions There appears to be an “obesity paradox” among acute myocardial infarction patients such that higher BMI is associated with lower mortality, an effect that was not modified by patient characteristics and was comparable across age, gender, and diabetes subgroups.

    Background The aim of the present study was to investigate risk factors for developing more severe pancreatitis, including moderately severe (MSAP) and severe acute pancreatitis (SAP), in patients admitted with mild acute pancreatitis (MAP). Material/Methods Patients admitted with MAP to our hospital from March 2013 to May 2016 were included and prospectively evaluated. Possible risk factors for developing MSAP or SAP were age, blood glucose level on admission, etiology, sex, Ranson score, amylase level, Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores, C-reactive protein (CRP) level, serum calcium level, visceral fat area (VFA), body mass index (BMI), whether this was the first episode of AP, and method of administration of octreotide. The effects of variables for developing MSAP or SAP were evaluated using univariate and multivariate logistic regression models. Mortality, hospital duration, and rate of ICU transfer of patients were compared between patients who developed MSAP or SAP and patients who did not. Results A total of 602 patients admitted with MAP were recruited into this study (256 men and 346 women). Seventy-four patients (12.3%) developed MSAP or SAP. According to univariate logistic regression analyses, the results indicated that there were 5 significant differences between patients who developed MSAP or SAP and those who did not: VFA (>100 cm2) (p=0.003), BMI (≥25 kg/m2) (p=0.001), Ranson score(p=0.004), APACHE-II (≥5) (p=0.001), and blood glucose level on admission (>11.1 mmol/L) (p=0.040). Further multivariate logistic regression analyses revealed that BMI (≥25 kg/m2) (p=0.005), APACHE-II (≥5) (p=0.001), and blood glucose level on admission (>11.1 mmol/L) (p=0.004) were independent risk factors for developing MSAP or SAP in patients admitted with MAP. Moreover, patients who developed MSAP or SAP had a mortality rate of 5.4%. Conclusions Significant risk factors for developing MSAP or SAP in patients admitted with MAP

    The pharmacokinetics of quinine were studied in six Nigerian patients during acute uncomplicated falciparum malaria and convalescent periods. An oral dose of 10 mg/kg quinine dihydrochloride administered 8-hourly for 7 days gave parasite and fever clearance times of 36.0 +/- 16.6 h and 18.0 +/- 6.4 h, respectively. From the individual quinine plasma profiles the mean plasma concentration of quinine at the time of parasite clearance was estimated as 4.5 +/- 1.1 micrograms/ml. Plasma quinine levels during malaria rose rapidly reaching a peak around the second and third days and declining thereafter as patients improved clinically. In acute malaria plasma quinine levels were more than two-fold higher than in convalescence; the mean AUC(0-12) in malaria was 37.9 +/- 14.7 micrograms.h/ml compared to 17.9 +/- 8.5 micrograms.h/ml in convalescence. The apparent oral clearance (CL/F) and volume of distribution (Vd/F) during the acute phase of the malaria (1.9 +/- 0.7 ml/min/kg and 1.8 +/- 0.9 l/kg, respectively) were significantly lower than in convalescence (4.5 +/- 2.1 ml/min/kg and 4.2 +/- 3.2 l/kg). The present data suggest that malaria parasites in African patients are still very sensitive to quinine and that the current dosage of quinine is effective for the treatment of acute falciparum malaria in African patients without augmenting therapy with any other drug such as tetracycline or sulphadoxine-pyrimethamine. It also confirms that malaria significantly alters the pharmacokinetics of quinine in humans.

    Pleural effusions occur frequently in mechanically ventilated patients, but no consensus exists regarding the clinical benefit of effusion drainage. We sought to determine the impact of thoracentesis on gas exchange in patients with differing severities of acute lung injury (ALI). A retrospective analysis was conducted on therapeutic thoracenteses performed on intubated patients in an adult surgical intensive care unit of a tertiary center. Effusions judged by ultrasound to be 400 mL or larger were drained. Subjects were divided into groups based on their initial P:F ratios: normal >300, ALI 200 to 300, and acute respiratory distress syndrome (ARDS) <200. Baseline characteristics, physiologic variables, arterial blood gases, and ventilator settings before and after the intervention were analyzed. The primary end point was the change in measures of oxygenation. Significant improvements in P:F ratios (mean ± SD) were seen only in patients with ARDS (50.4 ± 38.5, P = 0.001) and ALI (90.6 ± 161.7, P = 0.022). Statistically significant improvement was observed in the pO2 (31.1, P = 0.005) and O2 saturation (4.1, P < 0.001) of the ARDS group. The volume of effusion removed did not correlate with changes in individual patient's oxygenation. These data support the role of therapeutic thoracentesis for intubated patients with abnormal P:F ratios.

    Whereas in younger patients diagnosed with acute myeloid leukemia (AML) treatment is straightforward and the goal is cure, the optimal treatment decision for older adults remains highly controversial. Physicians need to determine whether palliation, “something” beyond palliation, intensive therapy, or an investigational therapy is the most appropriate treatment option. This requires understanding of the biology and risk profile of the AML, clinical judgment in evaluating the functional status of the patient, communication skills in understanding the patient's wishes and social background, and medical expertise in available therapies. The physician has to accurately inform the patient about (a) the unique biological considerations of his leukemia and his prognosis; (b) the risks and benefits of all available treatment options; (c) novel therapeutic approaches and how the patient can get access to these treatments. Last but not least, he has to recommend a treatment. This paper tries to discuss each of these issues. PMID:20628485

    Acute respiratory distress syndrome occupies a great deal of attention in intensive care units. Despite ample knowledge of the physiopathology of this syndrome, the focus in intensive care units consists mostly of life-supporting treatment and avoidance of the side effects of invasive treatments. Although great advances in mechanical ventilation have occurred in the past 20 years, with a significant impact on mortality, the incidence continues to be high. Patients with acute respiratory distress syndrome, especially the most severe cases, often present with refractory hypoxemia due to shunt, which can require additional treatments beyond mechanical ventilation, among which is mechanical ventilation in the prone position. This method, first recommended to improve oxygenation in 1974, can be easily implemented in any intensive care unit with trained personnel. Prone position has extremely robust bibliographic support. Various randomized clinical studies have demonstrated the effect of prone decubitus on the oxygenation of patients with acute respiratory distress syndrome measured in terms of the PaO2/FiO2 ratio, including its effects on increasing patient survival. The members of the Respiratory Therapists Committee of the Sociedad Argentina de Terapia Intensiva performed a narrative review with the objective of discovering the available evidence related to the implementation of prone position, changes produced in the respiratory system due to the application of this maneuver, and its impact on mortality. Finally, guidelines are suggested for decision-making. PMID:27925054

    Coronary artery aneurysms that occur in 25% of untreated Kawasaki disease (KD) patients may remain clinically silent for decades and then thrombose resulting in myocardial infarction. Although KD is now the most common cause of acquired heart disease in children in Asia, the United States, and Western Europe, the incidence of KD in Egypt is unknown. We tested the hypothesis that young adults in Egypt presenting with acute myocardial ischemia may have coronary artery lesions because of KD in childhood. We reviewed a total of 580 angiograms of patients ≤40 years presenting with symptoms of myocardial ischemia. Coronary artery aneurysms were noted in 46 patients (7.9%), of whom 9 presented with myocardial infarction. The likelihood of antecedent KD as the cause of the aneurysms was classified as definite (n = 10), probable (n = 29), or equivocal (n = 7). Compared with the definite and probable groups, the equivocal group had more traditional cardiovascular risk factors, smaller sized aneurysms, and fewer coronary arteries affected. In conclusion, in a major metropolitan center in Egypt, 6.7% of adults aged ≤40 years who underwent angiography for evaluation of possible myocardial ischemia had lesions consistent with antecedent KD. Because of the unique therapeutic challenges associated with these lesions, adult cardiologists should be aware that coronary artery aneurysms in young adults may be because of missed KD in childhood.

    There is a well explored relationship between quantum mechanical scattering from a potential and the Korteweg-de Vries (KdV) equation of fluid dynamics: if the potential is ‘evolved’ according to the KdV equation then it will have the same reflectivity and transmissivity as a function of energy, for each snapshot in time. In this work we explore this connection in optics, where the permittivity plays the role of the potential. We begin by deriving the relationship between the Helmholtz equation and the KdV equation in terms of the current induced in a material when a permittivity profile is changed slightly. It is then shown that the KdV equation can be used to design a plethora of bounded complex potentials that are relfectionless from both sides for all angles of incidence, and planar periodic media that exhibit a real Bloch vector for all angles of propagation. Finally we apply the KdV equation to reduce the reflection of a wave from an interface between two media of differing refractive indices.

    2015-01-01

    Acute kidney injury (AKI) is a frequent clinical event in patients with liver disease, compounding their prognosis. Furthermore, it is likely that the occurrence of AKI has a detrimental impact on the subsequent renal function and the long-term survival of these patients. Recently, some authors advocated the use of new diagnostic criteria for detecting acute kidney injury in patients with cirrhosis. These criteria are based on the rapidity and extent of the creatinine increase comparing to the basal creatinine and also on the kinetics of diuresis decrease. Although their validity in this population requires further studies to be clearly established, these new criteria could have two advantages: (1) to allow earlier diagnosis of AKI and, thus, hepatorenal syndrome for which earlier intervention could improve patients’ survival; and (2) to promote more intensive monitoring of renal function in these patients with high risk of AKI. Finally, recent practice guidelines about the prevention and treatment of general AKI have been published which should be useful in optimising the management of AKI in cirrhotic patients.

    Strate, Lisa L.; Gralnek, Ian M.

    2016-01-01

    This guideline provides recommendations for the management of patients with acute overt lower gastrointestinal hemorrhage. Hemodynamic status should be initially assessed with intravascular volume resuscitation started as needed. Risk stratification based upon clinical parameters should be performed to help distinguish patients at high and low-risk of adverse outcomes. Hematochezia associated with hemodynamic instability may be indicative of an upper GI bleeding source and thus warrants an upper endoscopy. In the majority of patients, colonoscopy should be the initial diagnostic procedure and should be performed within 24 hours of patient presentation after adequate colon preparation. Endoscopic hemostasis therapy should be provided to patients with high risk endoscopic stigmata of bleeding including active bleeding, non-bleeding visible vessel, or adherent clot. The endoscopic hemostasis modality used (mechanical, thermal, injection or combination) is most often guided by the etiology of bleeding, access to the bleeding site, and endoscopist experience with the various hemostasis modalities. Repeat colonoscopy, with endoscopic hemostasis performed if indicated, should be considered for patients with evidence of recurrent bleeding. Radiographic interventions (tagged red blood cell scintigraphy, CT angiography, angiography) should be considered in high-risk patients with ongoing bleeding who do not respond adequately to resuscitation, and who are unlikely to tolerate bowel preparation and colonoscopy. Strategies to prevent recurrent bleeding should be considered. NSAID use should be avoided in patients with a history of acute lower GI bleeding particularly if secondary to diverticulosis or angioectasia. In patients with established cardiovascular disease who require aspirin (secondary prophylaxis), aspirin should not be discontinued. The exact timing depends on the severity of bleeding, perceived adequacy of hemostasis and the risk of a thromboembolic event. Surgery

    2015-01-01

    The occurrence of dyspnoea in acute coronary syndrome (ACS) patients has always been considered a challenging diagnostic and therapeutic clinical scenario. P2Y12 platelet receptor inhibitors (i.e., clopidogrel, prasugrel and ticagrelor) are currently the cornerstone of treatment of ACS patients. Thus, in the last few years, the potential association between ACS and dyspnoea has also become more challenging with the increasing use of ticagrelor in these patients due to its beneficial effects on ischaemic event prevention and mortality, since ticagrelor can induce dyspnoea as a side effect. The present article is intended to review the current literature regarding dyspnoea occurrence in ACS patients, especially those treated with ticagrelor, and to propose ticagrelor-associated dyspnoea management recommendations based on current knowledge.

    Patients with acute brain injury (ABI) frequently require diagnostic and therapeutic procedures in the areas located outside of the intensive care unit. Transports can be risky for critically ill patients with ABI. Secondary brain injury can occur during the transport from causes such as ischemia, hypotension, hypoxia, hypercapnia, and cerebral edema. Preparation and implementation of preventive procedures including pretransport assessment, monitoring during transport, and posttransport examination and documentation for transports of patients with ABI deem to be necessary. The purpose of this article is to review the typical risks associated with the transports of the patients with ABI out of the intensive care unit and to propose the strategies that can be used to minimize the risks of secondary brain injury.

    Toxoplasmosis is an infectious disease caused by the intracellular parasite Toxoplasma gondii. In Switzerland about a third of the population has antibodies against this pathogen and has thus already been in contact with the parasite or has contracted the disease. Immunocompetent patients are usually asymptomatic (80-90%) during primary infection. The most common symptom is neck or occipital lymphadenopathy. Serology is the diagnostic gold standard in immunocompetent individuals. The presence of IgM antibodies is however not sufficient to make a definite diagnosis of acute toxoplasmosis. Distinction between acute and chronic toxoplasmosis requires additional serological tests (IgG avidity test). If required, the most used and probably most effective treatment is the combination of pyrimethamine and sulfadiazine, with folinic acid.

    Meeting patients' fundamental care needs is essential for optimal safety and recovery and positive experiences within any healthcare setting. There is growing international evidence, however, that these fundamentals are often poorly executed in acute care settings, resulting in patient safety threats, poorer and costly care outcomes, and dehumanising experiences for patients and families. Whilst care standards and policy initiatives are attempting to address these issues, their impact has been limited. This discussion paper explores, through a series of propositions, why fundamental care can be overlooked in sophisticated, high technology acute care settings. We argue that the central problem lies in the invisibility and subsequent devaluing of fundamental care. Such care is perceived to involve simple tasks that require little skill to execute and have minimal impact on patient outcomes. The propositions explore the potential origins of this prevailing perception, focusing upon the impact of the biomedical model, the consequences of managerial approaches that drive healthcare cultures, and the devaluing of fundamental care by nurses themselves. These multiple sources of invisibility and devaluing surrounding fundamental care have rendered the concept underdeveloped and misunderstood both conceptually and theoretically. Likewise, there remains minimal role clarification around who should be responsible for and deliver such care, and a dearth of empirical evidence and evidence-based metrics. In explicating these propositions, we argue that key to transforming the delivery of acute healthcare is a substantial shift in the conceptualisation of fundamental care. The propositions present a cogent argument that counters the prevailing perception that fundamental care is basic and does not require systematic investigation. We conclude by calling for the explicit valuing and embedding of fundamental care in healthcare education, research, practice and policy. Without this

    Acute heart failure (AHF) is the most common cause of unplanned hospital admissions, and is associated with high mortality rates. Over the next few decades, the combination of improved cardiovascular disease survival and progressive ageing of the population will further increase the prevalence of AHF in developed countries. New recommendations on the management of AHF have been published recently, but as elderly patients are under-represented in clinical trials, and scientific evidence is often lacking, the diagnosis and management of AHF in this population is challenging. The clinical presentation of AHF, especially in patients aged>85years, differs substantially from that in younger patients, with unspecific symptoms, such as fatigue and confusion, often overriding dyspnoea. Older patients also have a different risk profile compared with younger patients: often heart failure with preserved ejection fraction, and infection as the most frequent precipitating factor of AHF. Moreover, co-morbidities, disability and frailty are common, and increase morbidity, recovery time, readmission rates and mortality; their presence should be detected during a geriatric assessment. Diagnostics and treatment for AHF should be tailored according to cardiopulmonary and geriatric status, giving special attention to the patient's preferences for care. Whereas many elderly AHF patients may be managed similarly to younger patients, different strategies should be applied in the presence of relevant co-morbidities, disability and frailty. The option of palliative care should be considered at an early stage, to avoid unnecessary and harmful diagnostics and treatments.

    Previous case reports and retrospective studies suggest that pituitary dysfunction may occur after acute bacterial or viral meningitis. In this prospective study we assessed the pituitary functions, lipid profile and anthropometric measures in adults with acute bacterial or viral meningitis. Moreover, in order to investigate whether autoimmune mechanisms could play a role in the pathogenesis of acute meningitis-induced hypopituitarism we also investigated the anti-pituitary antibodies (APA) and anti-hypothalamus antibodies (AHA) prospectively. Sixteen patients (10 males, 6 females; mean ± SD age 40.9 ± 15.9) with acute infectious meningitis were included and the patients were evaluated in the acute phase, and at 6 and 12 months after the acute meningitis. In the acute phase 18.7% of the patients had GH deficiency, 12.5% had ACTH and FSH/LH deficiencies. At 12 months after acute meningitis 6 of 14 patients (42.8%) had GH deficiency, 1 of 14 patients (7.1%) had ACTH and FSH/LH deficiencies. Two of 14 patients (14.3%) had combined hormone deficiencies and four patients (28.6%) had isolated hormone deficiencies at 12 months. Four of 9 (44.4%) hormone deficiencies at 6 months were recovered at 12 months, and 3 of 8 (37.5%) hormone deficiencies at 12 months were new-onset hormone deficiencies. At 12 months there were significant negative correlations between IGF-I level vs. LDL-C, and IGF-I level vs. total cholesterol. The frequency of AHA and APA positivity was substantially high, ranging from 35 to 50% of the patients throughout the 12 months period. However there were no significant correlations between AHA or APA positivity and hypopituitarism. The risk of hypopituitarism, GH deficiency in particular, is substantially high in the acute phase, after 6 and 12 months of the acute infectious meningitis. Moreover we found that 6th month after meningitis is too early to make a decision for pituitary dysfunction and these patients should be screened for at least 12 months

    Hospitalists and others acute care providers are limited by gaps in evidence addressing the needs of the acutely ill older adult population. The Society of Hospital Medicine (SHM) sponsored the Acute Care of Older Patients (ACOP) Priority Setting Partnership to develop a research agenda focused on bridging this gap. Informed by the Patient-Centered Outcomes Research Institute (PCORI) framework for identification and prioritization of research areas, we adapted a methodology developed by the James Lind Alliance to engage diverse stakeholders in the research agenda setting process. The work of the Partnership proceeded through four steps: convening, consulting, collating, and prioritizing. First, the steering committee convened a Partnership of 18 stakeholder organizations in May 2013. Next, stakeholder organizations surveyed members to identify important unanswered questions in the acute care of older persons, receiving 1299 responses from 580 individuals. Finally, an extensive and structured process of collation and prioritization resulted in a final list of ten research questions in the following areas: advanced care planning, care transitions, delirium, dementia, depression, medications, models of care, physical function, surgery, and training. With the changing demographics of the hospitalized population, a workforce with limited geriatrics training, and gaps in evidence to inform clinical decision-making for acutely ill older patients, the identified research questions deserve the highest priority in directing future research efforts to improve care for the older hospitalized patient and enrich training.

    Seven cases with acute cervical cord lesions associated with a fit and fall, were found in approximately 500 patients with epilepsy over a period of 7 years. In all patients the epilepsy was refractory to drug therapy and six suffered tonic fits which resulted in falls and frequent head injuries. Notable radiological changes were found in the cervical spine; there was ankylosis in five, hyperostosis in four and the minimum sagittal diameter of the bony canal was less than 11mm in three cases. The findings indicate that repetitive trauma may be a factor in producing bony changes in the cervical spine which put the patient at risk of cervical cord injury, especially when the spinal canal is developmentally narrow.

    Acute and severe hyponatremia causes a metabolic encephalothy. It is physiopathologically based on the cerebral edema, and its fatal symptoms include seizures and coma. We present a case of an extreme hyponatremia of multifactorial etiology in a schizophrenic patient with potomania. Potomania does not usually cause hyponatremia, unless it coexists with other trigger factors. This patient had a syndrome of inappropriate antidiuretic hormone (SIADH), and a deep hypokaliemia, due to vomiting and a treatment with indapamida, which perpetuates the deficit of extracellular sodium. In the patient's treatment, aripiprazole was the only recently introduced drug with which cases of inappropriate vasopressin secretion have been reported. Management of a severe hyponatremia must be considered a vital emergency, independent of the cause, and 3% hypertonic saline must be administered. The increase of the sodium level must not be higher than 25 mmol/L in the first 24-48 hours, to avoid a secondary brain injury.

    Acute myeloid leukemia (AML) is primarily a disease of older adults, for whom optimal treatment strategies remain controversial. Because of the concern for therapeutic resistance and, in particular, excessive toxicity or even treatment-related mortality, many older or medically unfit patients do not receive AML-directed therapy. Yet, evidence suggests that outcomes are improved if essentially all of these patients are offered AML therapy, ideally at a specialized cancer center. Medical fitness for tolerating intensive chemotherapy can be estimated relatively accurately with multiparameter assessment tools; this information should serve as basis for the assignment to intensive or non-intensive therapy. Until our accuracy in predicting the success of individual therapies improves, all patients should be considered for participation in a randomized controlled trial. Comparisons between individual trials will be facilitated once standardized, improved response criteria are developed, and standard treatment approaches have been defined against which novel therapies can be tested.

    Severe diarrheal illness in children can be attributed to a number of different microbiological agents. Without appropriate microbiological testing of stool samples, patients who present with multiple days of severe diarrhea might have a delay in proper diagnosis and treatment. Here, we report a case of an immunocompetent pediatric patient presenting with acute cryptosporidiosis. Humans and bovine species are known hosts of cryptosporidium and several studies have evaluated the zoonotic transmission of cryptosporidium from cattle to humans. Adding diagnostic tests for cryptosporidium like Ziehl-Neelsen staining of stool or fecal rapid antigen detection techniques should be considered in the workup of patients presenting with undifferentiated, severe diarrheal illness, especially in those who have close contact with livestock.

    Thrombin generation measurement may be of value for assessing the risk of venous thromboembolism, but its long term profile has not been assessed in patients. We evaluated thrombin generation by Calibrated Automated Thrombogram (CAT) in plasma during follow up of 104 consecutive patients after an acute episode of deep venous thrombosis. Blood was drawn three times over the course of 24 months. Thrombin generation was measured in absence and presence of thrombomodulin and compared to a reference range derived from thrombin generation curves in 137 healthy volunteers. Thrombin generation of patients showed significantly higher endogenous thrombin potential (ETP) and peak height compared to the reference population. Differences were more pronounced in assays triggered with 1 pM TF. Inhibition by thrombomodulin was attenuated in patients off anticoagulants as compared to the reference population (21% vs. 42.2%, p < 0.0001); inhibition in patients on anticoagulant treatment was less pronounced (9.7%, p < 0.0001). Protein C activity, protein S antigen as well as free protein S showed highly negative correlation with ETP in all patients. A significant negative relation was found between FVIII levels and thrombomodulin induced reduction of ETP and peak height. In conclusion, thrombin generation by CAT reflects changes in coagulation status in patients following a thromboembolic event and is most sensitive at CAT analysis triggered with 1 pM TF. A role for factor VIII as an important attributable cause of hypercoagulability is reflected by the reduced inhibitory effect of thrombomodulin at high factor VIII levels.

    Acute gastrointestinal bleeding represents the most common adverse event associated with the use of oral anticoagulant therapy. Due to increasing prescription of anticoagulants worldwide, gastroenterologists are more and more called to deal with bleeding patients taking these medications. Their management is challenging because several issues have to be taken into account, such as the severity of bleeding, the intensity of anticoagulation, the patient's thrombotic risk and endoscopy findings. The recent introduction into the marketplace of new direct oral anticoagulants, for whom specific reversal agents are still lacking, further contributes to make the decision-making process even more demanding. Available evidence on this topic is limited and practice guidelines by gastroenterology societies only marginally address key issues for clinicians, including when and how to reverse coagulopathy, the optimal timing of endoscopy and when and how to resume anticoagulation thereafter. The present paper reviews the evidence in the literature and provides practical algorithms to support clinicians in the management of patients on anticoagulants who present with acute gastrointestinal bleeding.

    Introduction: The purpose of this study was to evaluate our experience with initial percutaneous transluminal angioplasty (PTA) {+-} stenting as valuable options in the acute setting. Methods: Between 2003 and 2008, eight patients with abdominal angio-MDCT-scan proven thrombotic AMI benefited from initial PTA {+-} stenting. We retrospectively assessed clinical and radiological findings and their management. Seven patients presented thrombosis of the superior mesenteric artery, and in one patient both mesenteric arteries were occluded. All patients underwent initial PTA and stenting, except one who had balloon PTA alone. One patient was treated by additional in situ thrombolysis. Results: Technical success was obtained in all patients. Three patients required subsequent surgery (37.5%), two of whom had severe radiological findings (pneumatosis intestinalis and/or portal venous gas). Two patients (25%) died: both had NIDD, an ASA score {>=}4, and severe radiologic findings. Satisfactory arterial patency was observed after a follow-up of 15 (range, 11-17) months in five patients who did not require subsequent surgery, four of whom had abdominal guarding but no severe CT scan findings. One patient had an ileocecal stenosis 60 days after the procedure. Conclusions: Initial PTA {+-} stenting is a valuable alternative to surgery for patients with thrombotic AMI even for those with clinical peritoneal irritation signs and/or severe radiologic findings. Early surgery is indicated if clinical condition does not improve after PTA. The decision of a subsequent surgery must be lead by early clinical status reevaluation. In case of underlying atherosclerotic lesion, stenting should be performed after initial balloon dilatation.

    Cryoglobulins are immunoglobulins that precipitate at cold temperatures. Their presence can be related to a type of vasculitis referred to as cryoglobulinemia. This condition, especially mixed cryoglobulinemia, has been associated with viral infections like hepatitis C virus in 60%-90% of cases, but it has also been reported in relation to connective tissue diseases, usually resulting in a more severe course. We describe the case of a patient with seronegative polyarthritis who developed acute arterial ischemia in association with cryoglobulinemia, with a good response to rituximab therapy.

    Acute respiratory distress syndrome (ARDS) caused by pneumonia in patients with hematologic malignancies can be life-threatening. Extracorporeal membrane oxygenation (ECMO) is the only temporary treatment for patients with ARDS who are refractory to conventional treatment. However, the immunosuppression and coagulopathies in hematological malignancies such as lymphoma and acute leukemia are relative contraindications for ECMO, due to high risks of infection and bleeding. Here, we report a 22-year-old man with acute myeloid leukemia (AML) who developed pneumonia and ARDS during induction chemotherapy; he was treated with ECMO. PMID:28275497

    The literature suggests that effective teamwork among patient care teams can positively impact work environment, job satisfaction and quality of patient care. The purpose of this study was to determine the perceived level of nursing teamwork by registered nurses, registered practical nurses, personal support workers and unit clerks working on patient care teams in one acute care hospital in northern Ontario, Canada, and to determine if a relationship exists between the staff scores on the Nursing Teamwork Survey (NTS) and participant perception of adequate staffing. Using a descriptive cross-sectional research design, 600 staff members were invited to complete the NTS and a 33% response rate was achieved (N=200). The participants from the critical care unit reported the highest scores on the NTS, whereas participants from the inpatient surgical (IPS) unit reported the lowest scores. Participants from the IPS unit also reported having less experience, being younger, having less satisfaction in their current position and having a higher intention to leave. A high rate of intention to leave in the next year was found among all participants. No statistically significant correlation was found between overall scores on the NTS and the perception of adequate staffing. Strategies to increase teamwork, such as staff education, among patient care teams may positively influence job satisfaction and patient care on patient care units.

    Abstract Acute kidney injury (AKI) is overlooked in patients with pulmonary embolism (PE). Risk factors for and long-term outcomes of this complication remain unknown. This study evaluated the predictors and prognosis of AKI in patients with PE. This retrospective cohort study used Taiwan's National Health Insurance Research Database. We enrolled a total of 7588 patients who were admitted to a hospital for PE from January1997 to December 2011 and administered anticoagulation or thrombolytic agents. All demographic data, risk factors, and outcomes were analyzed. AKI was diagnosed in 372 (4.9%) patients. Multivariate logistic regression analysis revealed pre-existing chronic kidney disease, hypertension, diabetes mellitus, massive PE, anemia, and sepsis as independent risk factors for AKI. In the long-term follow-up, the survival rate was similar in the AKI and non-AKI groups. Careful risk factor screening and intensive intervention in patients with AKI might yield outcomes similar to those in patients without AKI. PMID:28248851

    Noninvasive ventilation (NIV) has an established efficacy to improve gas exchange and reduce the work of breathing in patients with hypoxemic acute respiratory failure. The clinical efficacy in terms of meaningful outcome is less clear and depends very much on patient selection and assessment of the risks of the technique. The potential risks include an insufficient reduction of the oxygen consumption of the respiratory muscles in case of shock, an excessive increase in tidal volume in case of lung injury, and a risk of delayed or emergent intubation. With a careful selection of patients and a rapid decision regarding the need for intubation in case of failure, great benefits can be offered to patients. Emerging indications include its use in patients with treatment limitations, in the postoperative period, and in patients with immunosuppression. This last indication will necessitate reappraisal because the prognosis of the conditions associated with immunosuppression has improved over the years. In all cases, there is both a time window and a severity window for NIV to work, after which delaying endotracheal intubation may worsen outcome. The preventive use of NIV seems promising in this setting but needs more research. An emerging interesting new option is the use of high flow humidified oxygen, which seems to be intermediate between oxygen alone and NIV.

    This study was undertaken to assess the impact of acute hyperglycemia (acute-HG) and chronic hyperglycemia (chronic-HG) on short-term outcomes in patients with acute myocardial infarction (AMI). This study consisted of 696 patients with AMI. Acute-HG was defined as admission plasma glucose ≥200 mg/dl and chronic-HG as hemoglobin A1c ≥6.5%. Acute-HG was associated with higher peak serum creatine kinase (4,094 ± 4,594 vs 2,526 ± 2,227 IU/L, p <0.001) and in-hospital mortality (9.8% vs 1.6%, p <0.001). On the contrary, there was no significant difference in peak creatine kinase (2,803 ± 2,661 vs 2,940 ± 3,181 IU/L, p = 0.59) and mortality (3.3 vs 3.7%, p = 0.79) between patients with chronic-HG and those without. Multivariate analysis showed that admission plasma glucose was an independent predictor of in-hospital mortality (odds ratio 1.15, 95% confidence interval 1.05 to 1.27, p <0.001), but hemoglobin A1c was not. When only patients with acute-HG were analyzed, chronic-HG was associated with a significantly smaller infarct size (3,221 ± 3,001 vs 5,904 ± 6,473 IU/L, p <0.001) and lower in-hospital mortality (5.5 vs 18.9%, p = 0.01). In conclusion, these results suggested that acute-HG, but not chronic-HG, was associated with adverse short-term outcomes after AMI. Paradoxically, in patients with acute-HG, chronic-HG might abate the adverse effects of acute-HG.

    Acute pancreatitis is a rare complication in postoperative colorectal cancer patients after FOLFOX6 (oxaliplatin + calcium folinate +5-FU [5-fluorouracil]) chemotherapy. In this paper, a total of 62 patients with gastrointestinal cancer were observed after the burst of acute pancreatitis. Surgery of the 62 cases of colorectal cancer patients was completed successfully. But when they underwent FOLFOX6 chemotherapy, five patients got acute pancreatitis (8.06%), four (6.45%) had mild acute pancreatitis, and one (1.61%) had severe acute pancreatitis, of which two were males (3.23%) and three females (4.84%). No patients (0.00%) had acute pancreatitis on the 1st day after chemotherapy; one patient (1.61%) got it in the first 2 and 3 days after chemotherapy; and three others (4.83%) got it in the first 4 days after chemotherapy. In the 62 patients with malignant tumors, the body mass index (BMI) was less than 18 (underweight) in six of them, with two cases of acute pancreatitis (33.33%); the BMI was 18–25 (normal weight) in 34 cases, with one case (2.94%) of acute pancreatitis; the BMI was 25–30 (overweight) in 13 cases, with 0 cases (0.00%) of acute pancreatitis; and the BMI was ≥30 (obese) in nine patients, with two cases of acute pancreatitis (22.22%). After symptomatic treatment, four patients were cured and one died; the mortality rate was 1.61%. Most of them appeared in the first 4 days after chemotherapy; the probability of this complication is significantly higher in slim and obese patients than in normal weight patients. Postoperative colorectal cancer patients after FOLFOX6 chemotherapy have a sudden onset of acute pancreatitis occult, especially in patients with severe acute pancreatitis; the symptoms are difficult to control, there is high mortality and it is worthy of clinician’s attention.

    AIM: To identify the possible predictors of early complications after the initial intervention in acute necrotizing pancreatitis. METHODS: We collected the medical records of 334 patients with acute necrotizing pancreatitis who received initial intervention in our center. Complications associated with predictors were analyzed. RESULTS: The postoperative mortality rate was 16% (53/334). Up to 31% of patients were successfully treated with percutaneous catheter drainage alone. The rates of intra-abdominal bleeding, colonic fistula, and progressive infection were 15% (50/334), 20% (68/334), and 26% (87/334), respectively. Multivariate analysis indicated that Marshall score upon admission, multiple organ failure, preoperative respiratory infection, and sepsis were the predictors of postoperative progressive infection (P < 0.05). Single organ failure, systemic inflammatory response syndrome upon admission, and C-reactive protein level upon admission were the risk factors of postoperative colonic fistula (P < 0.05). Moreover, preoperative Marshall score, organ failure, sepsis, and preoperative systemic inflammatory response syndrome were the risk factors of postoperative intra-abdominal bleeding (P < 0.05). CONCLUSION: Marshall score, organ failures, preoperative respiratory infection, sepsis, preoperative systemic inflammatory response syndrome, and C-reactive protein level upon admission are associated with postoperative complications.

    This case presented challenging diagnostic and management issues in a young healthy man who presented with abdominal pain and new-onset hypertension. The differential diagnosis evolved over the course of the clinical presentation. The patient had severe vascular involvement of his renal and basal cerebral arteries that initially was assumed to be due to a vasculitic process or hypercoagulable state. Finally it became apparent that the patient did not have a systemic illness but rather a localized vascular disease most likely due to segmental arterial mediolysis, a rare, under-recognized condition that can potentially be fatal. This condition is often difficult to distinguish from fibromuscular dysplasia. It is important to recognize and correctly diagnose the condition, particularly in the acute phase of the disease, because delay in diagnosis can contribute to morbidity and mortality. PMID:25583291

    This case presented challenging diagnostic and management issues in a young healthy man who presented with abdominal pain and new-onset hypertension. The differential diagnosis evolved over the course of the clinical presentation. The patient had severe vascular involvement of his renal and basal cerebral arteries that initially was assumed to be due to a vasculitic process or hypercoagulable state. Finally it became apparent that the patient did not have a systemic illness but rather a localized vascular disease most likely due to segmental arterial mediolysis, a rare, under-recognized condition that can potentially be fatal. This condition is often difficult to distinguish from fibromuscular dysplasia. It is important to recognize and correctly diagnose the condition, particularly in the acute phase of the disease, because delay in diagnosis can contribute to morbidity and mortality.

    Hypothermia, defined as an unintentional decline in the core body temperature to below 35℃, is a life-threatening condition. Patients with malnutrition and diabetes mellitus as well as those of advanced age are at high risk for accidental hypothermia. Due to the high mortality rates of accidental hypothermia, proper management is critical for the wellbeing of patients. Accidental hypothermia was reported to be associated with acute kidney injury (AKI) in over 40% of cases. Although the pathogenesis remains to be elucidated, vasoconstriction and ischemia in the kidney were considered to be the main mechanisms involved. Cases of AKI associated with hypothermia have been reported worldwide, but there have been few reports of hypothermia-induced AKI in Korea. Here, we present a case of hypothermia-induced AKI that was treated successfully with rewarming and supportive care.

    Acute myocardial infarction (AMI) in patients with immune thrombocytopenic purpura (ITP) is rare. We describe a case of AMI in patient with ITP. An 81-year-old woman presented with acute inferoposterior MI with low platelet count on admission (34,000/µl). Coronary angiography revealed significant mid right coronary artery (RCA) stenosis with thrombus, subsequently underwent successful percutaneous coronary intervention (PCI). In some patients with immune thrombocytopenia purpura and acute myocardial infarction, percutaneous coronary intervention is a therapeutic option.

    In some patients with acute myocardial infarction, thrombolytic therapy may be limited by its failure to reperfuse the occluded artery, by recurrent ischemia (despite initially successful reperfusion), and by major hemorrhagic complications. Primary coronary angioplasty may circumvent these limitations. This article reviews the results of primary angioplasty reported in patients with myocardial infarction and makes recommendations for its use. The review includes pertinent articles found in the English language literature from July 1987 to July 1993 on MEDLINE. Nonrandomized series of primary angioplasty in acute myocardial infarction have demonstrated high procedural success rates (86% to 99%) and infrequent recurrent ischemia (4%). Two randomized trials comparing primary angioplasty and thrombolytic therapy have shown that primary angioplasty results in lower mortality, less recurrent ischemia, shorter length of hospital stay, and improved left ventricular function. Two other randomized studies have shown little benefit from primary angioplasty on myocardial salvage, recurrent ischemia, or ventricular function. One major limitation of primary angioplasty is that it requires 24-hour availability of a catheterization laboratory and experienced surgical personnel. Primary angioplasty may be the preferred approach in patients with extensive myocardial infarction who have immediate (< 120 min) access to a cardiac catheterization laboratory with experienced personnel. Patients having 1) contraindications to thrombolytic therapy, 2) cardiogenic shock, 3) prior coronary bypass surgery, or 4) "stuttering" onset of pain may also benefit from primary angioplasty. Poor candidates for this procedure are those with a small myocardial infarction, those in whom undue delays in access to a cardiac catheterization facility would be expected, or those with complex coronary anatomy, including left main coronary artery disease.

    The relationship between acute coronary syndrome (ACS) and local and systemic inflammation, including accumulation of macrophages in atherosclerotic plaques and upregulation of blood cytokines (e.g., C-reactive protein (CRP)), has been known for more than 100 years. The atherosclerosis-associated inflammatory response has been traditionally considered as an immune system reaction to low-density lipoproteins. At the same time, some data have indicated a potential involvement of cytomegalovirus (CMV) in the activation and progression of atherosclerosis-associated inflammation, leading to ACS. However, these data have been tangential and mainly concerned the relationship between a coronary artery disease (CAD) prognosis and the anti-CMV antibody titer. We assumed that ACS might be associated with CMV reactivation and virus release into the bloodstream. The study’s aim was to test this assumption through a comparison of the plasma CMV DNA level in patients with various CAD forms and in healthy subjects. To our knowledge, no similar research has been undertaken yet. A total of 150 subjects (97 CAD patients and 53 healthy subjects) were examined. Real- time polymerase chain reaction (RT-PCR) was used to determine the number of plasma CMV DNA copies. We demonstrated that the number of plasma CMV genome copies in ACS patients was significantly higher than that in healthy subjects (p = 0.01). The CMV genome copy number was correlated with the plasma CRP level (p = 0.002). These findings indicate a potential relationship between CMV activation and atherosclerosis exacerbation that, in turn, leads to the development of unstable angina and acute myocardial infarction. Monitoring of the CMV plasma level in CAD patients may be helpful in the development of new therapeutic approaches to coronary atherosclerosis treatment. PMID:27437144

    Morbidly obese patients with body mass index greater than 40 kg/m(2) and respiratory failure requiring critical care services are increasingly seen in trauma and acute care surgical centers. Baseline respiratory pathophysiology including decreased pulmonary compliance with dependent atelectasis and abnormal ventilation-perfusion relationships predisposes these patients to acute lung injury (ALI) and adult respiratory distress syndrome (ARDS) as well as prolonged stays in the intensive care unit. Airway pressure release ventilation (APRV) is an increasingly used alternative mode for salvage therapy in patients with hypoxemic respiratory failure that also provides lung protection from ventilator-induced lung injury. APRV provides the conceptual advantage of an "open lung" approach to ventilation that may be extended to the morbidly obese patient population with ALI and ARDS. We discuss the theoretical benefits and a recent clinical experience of APRV ventilation in the morbidly obese patient with respiratory failure at a Level I trauma, surgical critical care, and acute care surgery center.

    Objectives Aspiration after stroke has been associated with aspiration pneumonia, which contributes to increased mortality of stroke. Laryngeal elevation is a core mechanism for protection from aspiration. Few studies have explored the predictive value of laryngeal elevation velocity for aspiration after stroke. This study aimed to explore the ability of laryngeal elevation velocity to predict aspiration in patients with acute ischemic stroke. Methods This was a prospective cohort study that included consecutive acute ischemic stroke patients treated at a teaching hospital during a 10-month period. Patients underwent magnetic resonance imaging (MRI) to confirm the diagnosis of acute ischemic stroke. Patients who were at risk of aspiration and could swallow 5 ml of diluted barium (40%, w/v) for a videofluoroscopic swallowing (VFS) study were included. The association between abnormal indices in the oral and pharyngeal phase of the VFS study and aspiration was examined using univariate analyses. These indices included the lip closure, tongue movement and control, laryngeal elevation velocity and range, the latency of pharyngeal swallowing, pharyngeal transit time (PTT), abnormal epiglottis tilt, residual barium in the pharynx, and the duration of upper esophageal sphincter (UES) opening. The laryngeal elevation velocity (%/s) was calculated as the range of laryngeal elevation (%) from the resting position to the maximum superior position or to the position where the laryngeal vestibule is fully closed divided by the corresponding duration of laryngeal elevation. The range of laryngeal elevation (%) was the percentage calculated as the distance between the resting laryngeal position and the maximum superior excursion position or position where the laryngeal vestibule is fully closed divided by the distance between the resting laryngeal position and the lowest edge of the mandible. A logistic regression analysis was used to determine the predictive value for aspiration

    Background: Intravenous thrombolysis (IVT) has now become a standard treatment in eligible patients with acute ischemic stroke (AIS) who present within 4.5 h of symptom onset. Objective: To determine the usefulness of IVT and the subset of patients who will benefit from IVT in AIS within 4.5 h. Materials and Methods: Patients with AIS within 4.5 h of symptom onset who underwent IVT were studied prospectively. The study period was from October 2011 to October 2015. Results: A total of 97 patients were thrombolysed intravenously. The mean onset to needle time in all patients was 177.2 ± 62 min (range: 60–360). At 3 months follow-up, favorable outcome was seen in 65 patients (67.1%) and poor outcome including death in the remaining 32 patients (32.9%). Factors predicting favorable outcome was age <65 years (P = 0.02), the National Institute of Health Stroke Scale (NIHSS) <15 (P < 0.001), small vessel occlusion (P = 0.006), cardioembolism (P = 0.006), and random blood sugar (RBS) <250 mg/dl (P < 0.001). Factors predicting poor outcome was diabetes mellitus (P = 0.01), dyslipidemia (P = 0.01), NIHSS at admission >15 (P = 0.03), RBS >250 mg/dl (P = 0.01), Dense cerebral artery sign, age, glucose level on admission, onset-to-treatment time, NIHSS on admission score >5 (P = 0.03), and occlusion of large artery (P = 0.02). Conclusion: Milder baseline stroke severity, blood glucose <250 mg/dL, younger patients (<65 years), cardioembolic stroke, and small vessel occlusion benefit from recombinant tissue plasminogen activator.

    Background The aim of this study was to determine the health care utilization of patients with acute coronary syndrome (ACS) of one German statutory health insurance. The utilization of ambulatory services as well as of inpatient rehabilitation should be regarded. Moreover, the study should reveal the prescription of drugs for secondary prevention. Here, patients showing guideline corresponding prescriptions should be compared with patients without such prescriptions. Methods A retrospective claims data analysis of one German statutory health insurance was conducted. Health care utilization was considered in the first year after an index hospitalization due to ACS. Beneficiaries for whom an ICD-10 discharge diagnosis of ACS was reported between January 1st 2007 and December 31st 2009 were included. In order to reveal differences in health care utilization depending on the type of ACS (STEMI versus NSTEMI/UA) stratified analyses were performed. Another stratification was done for patients with and without defined drug prescriptions. Results From 45,188 patients with ACS almost three quarters were assigned to the group of NSTEMI/UA. For 8.9% of all ACS patients (18.74% STEMI, 8.89% NSTEMI/UA), inpatient post-hospital rehabilitation related to ACS was recorded. Ambulatory care related to CHD diagnosis was utilized by 77.6% of patients, more often by STEMI than by NSTEMI/UA patients. For 36.7% and 45.7% of ACS patients, a prescription of aspirin or clopidogrel was recorded, respectively, 79.4% of STEMI patients received at least one prescription for antiplatelet drugs, the corresponding proportion of NSTEMI/UA was 59.8%. A considerable part of patients without prescription dropped out within the first 90 days after the index event. Conclusions A claims data analysis of one German statutory health insurance fund showed that health care utilization of ACS patients varied depending on the ACS type. It is necessary to distinguish between STEMI and NSTEMI/UA patients when

    Kawasaki disease (KD) is a type of systemic vasculitis that primarily affects children under the age of five years old. For sufferers of KD, intravenous immunoglobulin (IVIG) has been found to successfully diminish the occurrence of coronary artery lesions. Anemia is commonly found in KD patients, and we have shown that in appropriately elevated hepcidin levels are related to decreased hemoglobin levels in these patients. In this study, we investigated the time period of anemia and iron metabolism during different stages of KD. A total of 100 patients with KD and 20 control subjects were enrolled in this study for red blood cell and hemoglobin analysis. Furthermore, plasma, urine hepcidin, and plasma IL-6 levels were evaluated using enzyme-linked immunosorbent assay in 20 KD patients and controls. Changes in hemoglobin, plasma iron levels, and total iron binding capacity (TIBC) were also measured in patients with KD. Hemoglobin, iron levels, and TIBC were lower (p < 0.001, p = 0.009, and p < 0.001, respectively) while plasma IL-6 and hepcidin levels (both p < 0.001) were higher in patients with KD than in the controls prior to IVIG administration. Moreover, plasma hepcidin levels were positively and significantly correlated with urine hepcidin levels (p < 0.001) prior to IVIG administration. After IVIG treatment, plasma hepcidin and hemoglobin levels significantly decreased (both p < 0.001). Of particular note was a subsequent gradual increase in hemoglobin levels during the three weeks after IVIG treatment; nevertheless, the hemoglobin levels stayed lower in KD patients than in the controls (p = 0.045). These findings provide a longitudinal study of hemoglobin changes and among the first evidence that hepcidin induces transient anemia and hypoferremia during KD's acute inflammatory phase.

    Background Acute coronary syndromes (ACS) have been associated with lower health utilities (HUs) compared with the general population. Given the prognostic improvements after ACS with the implementation of coronary angiography (eg, percutaneous coronary intervention (PCI)), contemporary HU values derived from patient-reported outcomes are needed. Methods We analysed data of 1882 patients with ACS 1 year after coronary angiography in a Swiss prospective cohort. We used the EuroQol five-dimensional questionnaire (EQ-5D) and visual analogue scale (VAS) to derive HU indexes. We estimated the effects of clinical factors on HU using a linear regression model and compared the observed HU with the average values of individuals of the same sex and age in the general population. Results Mean EQ-5D HU 1-year after coronary angiography for ACS was 0.82 (±0.16) and mean VAS was 0.77 (±0.18); 40.9% of participants exhibited the highest utility values. Compared with population controls, the mean EQ-5D HU was similar (expected mean 0.82, p=0.58) in patients with ACS, but the mean VAS was slightly lower (expected mean 0.79, p<0.001). Patients with ACS who are younger than 60 years had lower HU than the general population (<0.001). In patients with ACS, significant differences were found according to the gender, education and employment status, diabetes, obesity, heart failure, recurrent ischaemic or incident bleeding event and participation in cardiac rehabilitation (p<0.01). Conclusions At 1 year, patients with ACS with coronary angiography had HU indexes similar to a control population. Subgroup analyses based on patients' characteristics and further disease-specific instruments could provide better sensitivity for detecting smaller variations in health-related quality of life.

    The clinical manifestation of acute corpus callosum (CC) infarction is lack of specificity and complex, so it is easily missed diagnosis and misdiagnosis in the early stage. The present study aims to describe the clinical features of the acute CC infarction. In this study, 25 patients with corpus callosum infarction confirmed by the brain MRI/DWI and the risk factors were summarized. Patients were classified into genu infarction (3 cases), body infarction (4cases), body and genu infarction (4 cases), body and splenium infarction (1 case), splenium infarction (13 cases) according to lesion location. Clinical manifestation and prognosis were analyzed among groups. The results indicated that CC infarction in patients with high-risk group accounted for 72%, moderate-risk group accounted for 20%, low-risk group (8%). The main risk factors are carotid intimal thickening or plaque formation, hypertension, hyperlipidemia, cerebral artery stenosis, and so on. The CC infarction often merged with other parts infarction, and splenium infarction had the highest incidence, the clinical symptoms in the body infarction which can appear typical signs and symptoms, but in other parts infarction which always merged many nerve defect symptoms. The body infarction prognosis is poor; the rest parts of infarction are more favorable prognosis. In conclusion, CC infarction has the highest incidence in the stroke of high-risk group; neck color Doppler and TCD examination can be found as early as possible to explore the pathogenic factors. Prognosis is usually much better by treatment according to the location and risk factors. PMID:25197390

    The pathogenesis and progression of many tumors, including hematologic malignancies is highly dependent on enhanced lipogenesis. De novo fatty-acid synthesis permits accelerated proliferation of tumor cells by providing membrane components but these may also alter physicochemical properties of lipid bilayers, which can impact signaling or even increase drug resistance in cancer cells. Cancer type-specific lipid profiles would permit us to monitor and interpret actual effects of lipid changes, potential fingerprints of individual tumors to be explored as diagnostic markers. We have used the shotgun MS approach to identify lipid patterns in different types of acute myeloid leukemia (AML) patients that either show no karyotype change or belong to t(8;21) or inv16 types. Differences in lipidomes of t(8;21) and inv(16) patients, as compared to AML patients without karyotype change, presented mostly as substantial modulation of ceramide/sphingolipid synthesis. Furthermore, between the t(8;21) and all other patients we observed significant changes in physicochemical membrane properties. These were related to a marked alteration in lipid saturation levels. The discovered differences in lipid profiles of various AML types improve our understanding of the pathobiochemical pathways involved and may serve in the development of diagnostic tools.

    Respiratory injuries by smoke inhalation are one of the most frequent reasons for acute respiratory failure in burn victims. They are most often of chemical origin and are responsible of a 20 to 70% increase of the mortality compared to the mortality of patients with similar burn injuries, but without inhalation lesions. They are often associated to a certain degree to other factors of acute respiratory failure: superior air way obstruction by oedema in face and neck burns, thoracic expansion hindrance due to thoracic burns, lung trauma lesions by blast injury. The generalized inflammatory reaction due to the extent of burns and an initial inadequate resuscitation are worsening factors. The inflammatory process may be responsible of lung injuries similar to those induced by smoke inhalation, even when there is no inhalation. The treatment remains symptomatic and based on the oxygen therapy, mechanical ventilation, prevention of infections and maintain of homeostasis by hydroelectrolytic adequate resuscitation. The nitric oxyde associated to the almitrin allows in a certain number of cases to minimize intra pulmonary shunting and to normalize the VA/O ratio. The development of treatments allowing to modulate inflammatory mediators may lead to news therapies in the future.

    Kawasaki disease (KD) is an acute vasculitis affecting mainly infants and children. Human B cells express Toll-like receptor (TLR)-9, whose natural ligands are unmethylated cytosine–guanine dinucleotide (CpG) motifs characteristic of bacterial DNA. The aim of this study was to clarify the pathogenesis of KD analysing the activation status of peripheral blood mononuclear cells (PBMC), focusing on B lymphocyte activation and functions. Ten patients and 10 age-matched healthy donors were recruited from the Bambino Gesù Hospital of Rome, Italy and enrolled into this study. We determined phenotype profile and immunoglobulin (Ig) production of PBMC from KD patients and age-matched controls. We found that the frequency of CD19+ B lymphocytes and CD19+/CD86+ activated B lymphocytes from KD patients during the acute phase before therapy was increased significantly. Moreover, B lymphocytes of acute-phase KD patients were more prone to CpG oligodeoxynucleotide (ODN) activation compared with the age-matched controls, as assessed by a significant increase of the number of IgA-secreting cells (SC). In the same patients we found a marked increase of IgM, IgG, interleukin (IL)-6 and tumour necrosis factor (TNF)-α production compared with the control group. In addition, in two convalescent KD patients, conventional treatment with intravenous immunoglobulin (IVIG) restored the normal frequency of CD19+ B cells, the number of IgA-, IgM- and IgG-SC and the production of IL-6 and TNF-α. Our findings indicate that the percentages of peripheral B lymphocytes of acute-phase KD patients are increased and are prone to bacterial activation in terms of increased numbers of IgA-SC and increased production of IL-6 and TNF-α inflammatory cytokines. Thus, our data support the hypothesis of an infectious triggering in KD. PMID:21175593

  2. Midostaurin: an emerging treatment for acute myeloid leukemia patients

    2016-01-01

    Acute myeloid leukemia (AML) is a hematologic malignancy that carries a poor prognosis and has garnered few treatment advances in the last few decades. Mutation of the internal tandem duplication (ITD) region of fms-like tyrosine kinase (FLT3) is considered high risk for decreased response and overall survival. Midostaurin is a Type III receptor tyrosine kinase inhibitor found to inhibit FLT3 and other receptor tyrosine kinases, including platelet-derived growth factor receptors, cyclin-dependent kinase 1, src, c-kit, and vascular endothelial growth factor receptor. In preclinical studies, midostaurin exhibited broad-spectrum antitumor activity toward a wide range of tumor xenografts, as well as an FLT3-ITD-driven mouse model of myelodysplastic syndrome (MDS). Midostaurin is orally administered and generally well tolerated as a single agent; hematologic toxicity increases substantially when administered in combination with standard induction chemotherapy. Clinical trials primarily have focused on relapsed/refractory AML and MDS and included single- and combination-agent studies. Administration of midostaurin to relapsed/refractory MDS and AML patients confers a robust anti-blast response sufficient to bridge a minority of patients to transplant. In combination with histone deacetylase inhibitors, responses appear comparable to historic controls, while the addition of midostaurin to standard induction chemotherapy may prolong survival in FLT3-ITD mutant patients. The response of some wild-type (WT)-FLT3 patients to midostaurin therapy is consistent with midostaurin’s ability to inhibit WT-FLT3 in vitro, and also may reflect overexpression of WT-FLT3 in those patients and/or off-target effects such as inhibition of kinases other than FLT3. Midostaurin represents a well-tolerated, easily administered oral agent with the potential to bridge mutant and WT-FLT3 AML patients to transplant and possibly deepen response to induction chemotherapy.

    Talaromyces marneffei (also called Penicilliosis Marneffei or T. marneffei) is a rare fungal disease that is prevalent mainly in Southeast Asia and commonly seen in immunocompromised hosts. It was rarely observed in immunocompetent hosts. We report a case of acute disseminated T. marneffei in an immunocompetent patient in the non-prevalent region. This patient had never visited the endemic area. The patient experienced a persistent fever. Brain CT and magnetic resonance imaging (MRI) showed a mass in the right frontal with osteolytic damage. Excessive white blood cell (WBC) count and C-reactive protein content were observed. Antibiotics including meropenem and linezolid could not play an effect, and another two hard masses appeared in his right neck and front chest wall. The aspirates from the right frontal mass and bone marrow were cultured. The final diagnose of this infection was disseminated T. marneffei. After voriconazole treatment, all symptoms improved gradually. We present this case and aim to promote more clinicians and microbiologists in the non-endemic region to recognize this rare disease.

    Acute myeloid leukemia (AML) is the second most common form of leukemia and the most frequent cause of leukemia-related deaths in the United States. The incidence of AML increases with advancing age and the prognosis for patients with AML worsens substantially with increasing age. Many older patients are ineligible for intensive treatment and require other therapeutic approaches to optimize clinical outcome. To address this treatment gap, novel agents with varying mechanisms of action targeting different cellular processes are currently in development. Hypomethylating agents (azacitidine, decitabine, SGI-110), histone deacetylase inhibitors (vorinostat, pracinostat, panobinostat), FMS-like tyrosine kinase receptor-3 inhibitors (quizartinib, sorafenib, midostaurin, crenolanib), cytotoxic agents (clofarabine, sapacitabine, vosaroxin), cell cycle inhibitors (barasertib, volasertib, rigosertib) and monoclonal antibodies (gentuzumab ozogamicin, lintuzumab-Ac225) represent some of these promising new treatments. This review provides an overview of novel agents that have either completed or are currently in ongoing phase III trials in patients with previously untreated AML for whom intensive treatment is not an option. Other potential drugs in earlier stages of development will also be addressed in this review.

    Paraquat concentration-time data have been used to predict the clinical outcome following ingestion. However, these studies have included only small populations, although paraquat poisoning has a very high mortality rate. The purpose of this study was to develop a simple and reliable model to predict survival according to the time interval post-ingestion in patients with acute paraquat poisoning. Data were retrospectively collected for patients who were admitted with paraquat poisoning to Soonchunhyang University Choenan Hospital between January 2005 and December 2012. Plasma paraquat levels were measured using high-performance liquid chromatography. To validate the model we developed, we used external data from 788 subjects admitted to the Presbyterian Medical Center, Jeonju, Korea, between January 2007 and December 2012. Two thousand one hundred thirty six patients were included in this study. The overall survival rate was 44% (939/2136). The probability of survival for any specified time and concentration could be predicted as (exp(logit))/(1+exp(logit)), where logit = 1.3544+[-3.4688 × log10(plasma paraquat μg/M[Formula: see text])]+[-2.3169 × log10(hours since ingestion)]. The external validation study showed that our model was highly accurate for the prediction of survival (C statics 0.964; 95% CI [0.952-0.975]). We have developed a model that is effective for predicting survival after paraquat intoxication.

    BACKGROUND Few studies have evaluated the association between patient expectations for recovery and clinical outcomes, and no study has evaluated whether asking patients to choose their therapy modifies such an association. OBJECTIVE To evaluate the association between patients’ expectations and functional recovery in patients with acute low back pain (LBP), and to determine whether that association is affected by giving patients choice of therapy. DESIGN AND PARTICIPANTS A secondary analysis of a randomized controlled trial comparing usual care alone to usual care plus choice of chiropractic, acupuncture, or massage in 444 adults with acute LBP, lasting less than 21 days. MEASUREMENTS AND MAIN RESULTS Primary outcome was functional disability (Roland score) at 5 and 12 weeks. Patients’ general expectations for improvement were associated with improvement in functional status (β = 0.96, 95% CI = 0.56, 1.36). A 1-point increase in general expectations was associated with a 0.96-point improvement in Roland score. The association of expectation with outcome was 2–3 times greater in the usual care group than the choice group. However, these differences did not reach statistical significance. CONCLUSIONS In patients with acute LBP, higher expectations for recovery are associated with greater functional improvement. Eliciting patient expectations for improvement may be a simple way to identify patients with the highest (or lowest) likelihood of experiencing functional improvement. Incorporating questions about patient expectations in future trials may clarify the role of this important correlate of clinical outcomes. PMID:18066631

    Although dexamethasone is highly effective in the treatment of pediatric acute lymphoblastic leukemia (ALL), it can cause serious metabolic side effects. Because studies regarding the effects of dexamethasone are limited by their small scale, we prospectively studied the direct effects of treating pediatric ALL with dexamethasone administration with respect to activation of components of metabolic syndrome (MetS); in addition, we investigated whether these side effects were correlated with the level of dexamethasone. Fifty pediatric patients (3–16 years of age) with ALL were studied during a 5-day dexamethasone course during the maintenance phase of the Dutch Childhood Oncology Group ALL-10 and ALL-11 protocols. Fasting insulin, glucose, total cholesterol, HDL, LDL, and triglycerides levels were measured at baseline (before the start of dexamethasone; T1) and on the fifth day of treatment (T2). Dexamethasone trough levels were measured at T2. We found that dexamethasone treatment significantly increased the following fasting serum levels (P<0.05): HDL, LDL, total cholesterol, triglycerides, glucose, and insulin. In addition, dexamethasone increased insulin resistance (HOMA-IR>3.4) from 8% to 85% (P<0.01). Dexamethasone treatment also significantly increased the diastolic and systolic blood pressure. Lastly, dexamethasone trough levels (N = 24) were directly correlated with high glucose levels at T2, but not with other parameters. These results indicate that dexamethasone treatment acutely induces three components of the MetS. Together with the weight gain typically associated with dexamethasone treatment, these factors may contribute to the higher prevalence of MetS and cardiovascular risk among survivors of childhood leukemia who received dexamethasone treatment.

    Patients with tree pollinosis frequently report allergic reactions after ingestion of apples. The severity of apple allergy has been related to the variety of apples and their degree of maturity. To generate a serum pool that is representative of various IgE-binding patterns of apple-allergic sera, serum samples from 34 patients allergic to tree pollens were screened. Only 24 serum samples reacted to the apple extract. Pooled serum was used to identify allergens in apples. An efficient and consistent extraction method for apple fruits was used to compare the immunoreactivities of extracts of different varieties (McIntosh, Red Delicious, Granny Smith, and Golden Delicious) of freshly picked and store-purchased apples. We found that Golden Delicious apples had the greatest amount of the 18 kd allergen, which has been reported to be a potent IgE-binding apple allergen. Store-purchased apples contained higher concentrations of the 18 kd allergen than freshly picked apples. In our study only 37.5% of sera reacted to the 18 kd protein, whereas 75% of the sera reacted to a 31 kd allergen. Other immunoreactive bands in apple extracts included proteins of 50, 38, 16, 14, and 13 kd. The amino-terminal amino acid sequences of the two major allergens, 18 kd and 31 kd, were determined. These sequences shared approximately 50% identity with disease resistance proteins of various plants or Bet v 1 in birch tree pollens. The appearance of various allergens was also investigated in mature apples during storage. The amount of 18 kd allergen increased significantly when apples were stored at 4 degrees C. However, under controlled atmospheric conditions in which oxygen- and carbon dioxide-induced ripening were regulated, the amount of 18 kd allergen remained unaffected. Because ripening and maturation were not associated with increases in 18 kd allergen content, the observed changes might be induced by factors related to disease resistance.

    To conduct a kinetic study of paraquat (PQ), we investigated 9 patients with acute PQ intoxication. All of them ingested more than 20 ml of undiluted PQ herbicide to commit suicide and arrived at our hospital early, not later than 7 h after PQ ingestion. The urine dithionite test for PQ in all of the nine patients was strongly positive at emergency room. Blood samples were obtained every 30 min for the first 2~3 h and then every 1 or 2 h, as long as the clinical progression was stable among the patients for 30 h after PQ ingestion. The area under the plasma concentration-time curve (AUCinf), which was extrapolated to infinity, was calculated using the trapezoidal rule. Toxicokinetic parameters, such as the terminal elimination half-life, apparent oral clearance, and apparent volume of distribution (Vd/F) were calculated. The maximum PQ concentration (Cmax) and the time to reach maximum PQ concentration (Tmax) were also obtained. Plasma PQ concentrations in nine patients were well described by a bi-exponential curve with a mean terminal elimination half-life of 13.1±6.8 h. Cmax and AUCinf were 20.8±25.7 mg/l and 172.5±160.3 h·mg/l, respectively. Apparent volume of distribution and apparent oral clearance were 50.9±61.3 l/kg and 173.4±111.2 l/h, respectively. There were a significant correlation (r =0.84; p<0.05) between the PQ amount ingested and Cmax. AUCinf also showed a significant correlation (r =0.83; p<0.05) with the PQ amount ingested. These correlations provide evidence that PQ has dose-linear toxicokinetic characteristics. PMID:26807021

    Injuries constitute a major public health problem. Millions of people are injured each year, and acute drinking is a well-known risk factor for injuries. Research suggests that acknowledgment of alcohol as a factor in an injury enhances willingness to change drinking behavior, possibly because the patient becomes aware of the negative consequences of their drinking. This study aims to investigate the prevalence of acute alcohol consumption (drinking before the event) among injury patients and to examine the importance of factors potentially associated with motivation to reduce alcohol consumption among these patients. All patients aged 18-69 years were requested to answer alcohol-related questions on a touchscreen computer. Fifteen percent of injured patients were categorized as acute drinkers, and of these, 64% reported that their injury was connected to alcohol. There were significant differences for all sociodemographic and drinking characteristics between acute drinkers and nonacute drinkers. Acute drinkers were categorized as risky drinkers to a much higher extent than nonacute drinkers. Acute drinkers had a considerably higher average weekly alcohol consumption and engaged far more frequently in heavy episodic drinking than nonacute drinkers. Acute drinkers were motivated to reduce their alcohol intake to a greater extent than nonacute drinkers; 51% were in the action, preparation, and contemplation stages, compared with 19% of the nonacute drinkers. Acute drinkers had considerably more detrimental alcohol consumption than nonacute drinkers, and the acute drinkers were more motivated to reduce their drinking than the nonacute drinkers.

    Acute vasoreactivity testing for patients with pulmonary arterial hypertension (PAH) has been reported to be useful to identify patients with sustained beneficial response to oral calcium-channel blockers (CCBs), but there is a risk of exacerbation during the testing with oral CCBs. Therefore, we developed a testing method utilizing intravenous nicardipine, a short-acting CCB, and examined the safety and usefulness of acute vasoreactivity testing with nicardipine in PAH patients. Acute vasoreactivity testing with nicardipine was performed in 65 PAH patients. Nicardipine was administered by short-time continuous infusion (1 μg·kg⁻¹·min⁻¹ for 5 min and 2 μg·kg⁻¹·min⁻¹ for 5 min) followed by bolus injection (5 μg/kg). Hemodynamic responses were continuously measured using a right heart catheter. Acute responders were defined as patients who showed a decrease in mean pulmonary artery pressure of at least 10 mmHg to an absolute level below 40 mmHg with preserved or increased cardiac output. Two acute responders and sixty-three non-acute responders were identified. There was no hemodynamic instability requiring additional inotropic agents or death during the testing. Acute responders had good responses to long-term oral CCBs. The acute vasoreactivity testing with nicardipine might be safe and useful for identifying CCB responders in PAH patients.

    Daily interruption of sedative therapy and limitation of deep sedation have been shown in several randomized trials to reduce the duration of mechanical ventilation and hospital length of stay, and to improve the outcome of critically ill patients. However, patients with severe acute brain injury (ABI; including subjects with coma after traumatic brain injury, ischaemic/haemorrhagic stroke, cardiac arrest, status epilepticus) were excluded from these studies. Therefore, whether the new paradigm of minimal sedation can be translated to the neuro-ICU (NICU) is unclear. In patients with ABI, sedation has 'general' indications (control of anxiety, pain, discomfort, agitation, facilitation of mechanical ventilation) and 'neuro-specific' indications (reduction of cerebral metabolic demand, improved brain tolerance to ischaemia). Sedation also is an essential therapeutic component of intracranial pressure therapy, targeted temperature management and seizure control. Given the lack of large trials which have evaluated clinically relevant endpoints, sedative selection depends on the effect of each agent on cerebral and systemic haemodynamics. Titration and withdrawal of sedation in the NICU setting has to be balanced between the risk that interrupting sedation might exacerbate brain injury (e.g. intracranial pressure elevation) and the potential benefits of enhanced neurological function and reduced complications. In this review, we provide a concise summary of cerebral physiologic effects of sedatives and analgesics, the advantages/disadvantages of each agent, the comparative effects of standard sedatives (propofol and midazolam) and the emerging role of alternative drugs (ketamine). We suggest a pragmatic approach for the use of sedation-analgesia in the NICU, focusing on some practical aspects, including optimal titration and management of sedation withdrawal according to ABI severity.

    Differentiating acute Q fever from infections caused by other pathogens is essential. We conducted a retrospective case–control study to evaluate differences in clinical signs, symptoms, and outcomes for 82 patients with acute Q fever and 52 control patients who had pneumonia, fever and lower respiratory tract symptoms, or fever and hepatitis, but had negative serologic results for Q fever. Patients with acute Q fever were younger and had higher C-reactive protein levels but lower leukocyte counts. However, a large overlap was found. In patients with an indication for prophylaxis, chronic Q fever did not develop after patients received prophylaxis but did develop in 50% of patients who did not receive prophylaxis. Differentiating acute Q fever from other respiratory infections, fever, or hepatitis is not possible without serologic testing or PCR. If risk factors for chronic Q fever are present, prophylactic treatment is advised. PMID:26196955

    Kawasaki disease (KD) is a type of systemic vasculitis that primarily affects children under the age of five years old. For sufferers of KD, intravenous immunoglobulin (IVIG) has been found to successfully diminish the occurrence of coronary artery lesions. Anemia is commonly found in KD patients, and we have shown that in appropriately elevated hepcidin levels are related to decreased hemoglobin levels in these patients. In this study, we investigated the time period of anemia and iron metabolism during different stages of KD. A total of 100 patients with KD and 20 control subjects were enrolled in this study for red blood cell and hemoglobin analysis. Furthermore, plasma, urine hepcidin, and plasma IL-6 levels were evaluated using enzyme-linked immunosorbent assay in 20 KD patients and controls. Changes in hemoglobin, plasma iron levels, and total iron binding capacity (TIBC) were also measured in patients with KD. Hemoglobin, iron levels, and TIBC were lower (p < 0.001, p = 0.009, and p < 0.001, respectively) while plasma IL-6 and hepcidin levels (both p < 0.001) were higher in patients with KD than in the controls prior to IVIG administration. Moreover, plasma hepcidin levels were positively and significantly correlated with urine hepcidin levels (p < 0.001) prior to IVIG administration. After IVIG treatment, plasma hepcidin and hemoglobin levels significantly decreased (both p < 0.001). Of particular note was a subsequent gradual increase in hemoglobin levels during the three weeks after IVIG treatment; nevertheless, the hemoglobin levels stayed lower in KD patients than in the controls (p = 0.045). These findings provide a longitudinal study of hemoglobin changes and among the first evidence that hepcidin induces transient anemia and hypoferremia during KD’s acute inflammatory phase.

    Despite recognition that Acute Kidney Injury (AKI) leads to substantial increases in morbidity, mortality, and length of stay, accurate prognostication of these clinical events remains difficult. It remains unclear which approaches to variable selection and model building are most robust. We used data from a randomized trial of AKI alerting to develop time-updated prognostic models using stepwise regression compared to more advanced variable selection techniques. We randomly split data into training and validation cohorts. Outcomes of interest were death within 7 days, dialysis within 7 days, and length of stay. Data elements eligible for model-building included lab values, medications and dosages, procedures, and demographics. We assessed model discrimination using the area under the receiver operator characteristic curve and r-squared values. 2241 individuals were available for analysis. Both modeling techniques created viable models with very good discrimination ability, with AUCs exceeding 0.85 for dialysis and 0.8 for death prediction. Model performance was similar across model building strategies, though the strategy employing more advanced variable selection was more parsimonious. Very good to excellent prediction of outcome events is feasible in patients with AKI. More advanced techniques may lead to more parsimonious models, which may facilitate adoption in other settings.

    Several studies have demonstrated that G-CSF, GM-CSF and, in particular, IL-3 can effectively recruit acute myeloid leukaemia (AML) blasts into the cell cycle, resulting in a significant increase in cytosine-arabinoside (Ara-C) mediated cytotoxicity in vitro. Since IL-3 has shown biological and clinical activity, we investigated the cell kinetic effects of rIL-3 and high-dose Ara-C/idarubicin in three patients with refractory AML selected for the presence of chromosome 7 monosomy; this enabled differentiation between the effects of IL-3 on leukaemic and on normal cells. The in vivo administration of rhIL-3 (250 micrograms/m2d s.c. for 6-10d) recruited AML blasts into the cell cycle in two of the three patients, and this effect resulted in an increase in in vitro growth of clonogenic cells (CFU-L) and of their S-phase fraction. The percentage of leukaemic cells with monosomy 7 increased only in the two cases who showed a proliferative response. Normal cells were not recruited, even when rhIL-3 was administered for up to 10 d. In vitro studies showed an increased Ara-C cytotoxicity on clonogenic AML cells, in particular with IL-3 plus GM-CSF, thus confirming the priming effects of IL-3 in the two responding cases. The results of this study suggest that rhIL-3 can selectively recruit leukaemic cells into the cell cycle. Although leukaemic blasts can be sensitized to Ara-C, other mechanisms of primary blast resistance may limit the clinical benefit of kinetic-based approaches.

    Acute kidney injury in the setting of ascites and cirrhosis is a medical emergency characterized by significant morbidity and mortality. Clinicians other than gastroenterologists are often the front line against acute kidney injury for patients with ascites. Owing to the specifics of cirrhotic physiology, the treatment and prevention of acute kidney injury in the setting of ascites has unique features, widespread knowledge of which will benefit our patients with cirrhosis. Early detection and treatment of infection, maximization of cardiac output, and avoidance of medications that limit cardiorenal adaptations to arterial underfilling are part of a multipronged strategy to protect the renal function of our patients with cirrhosis and ascites.

    Understanding of the relation between the alcoholic consumption and the development of pancreatitis should help in defining the alcoholic etiology of pancreatitis. Although the association between alcohol consumption and pancreatitis has been recognized for over 100 years, it remains still unclear why some alcoholics develop pancreatitis and some do not. Surprisingly little data are available about alcohol amounts, drinking patterns, type of alcohol consumed and other habits such as dietary habits or smoking in respect to pancreatitis preceding the attack of acute pancreatitis or the time of the diagnosis of chronic pancreatitis. This review summarizes the current knowledge. Epidemiological studies clearly show connection between the alcohol consumption in population and the development of acute and chronic pancreatitis. In the individual level the risk to develop either acute or chronic pancreatitis increases along with the alcohol consumption. Moreover, the risk for recurrent acute pancreatitis after the first acute pancreatitis episode seems also to be highly dependent on the level of alcohol consumption. Abstaining from alcohol may prohibit recurrent acute pancreatitis and reduce pain in chronic pancreatitis. Therefore, all the attempts to decrease alcohol consumption after acute pancreatitis and even after the diagnosis of chronic pancreatitis should be encouraged. Smoking seems to be a remarkable co-factor together with alcohol in the development of chronic pancreatitis, whereas no hard data are available for this association in acute pancreatitis. Setting the limits for accepting the alcohol as the etiology cannot currently be based on published data, but rather on the 'political' agreement.

    We reported the oldest acute rheumatic fever (ARF) patient with initial attack at the age of 90 years and experience with ARF in adults in 20 years of observation. The case files of all ARF patients treated by rheumatology unit, Chiang Mai University, were reviewed. Demographic data and clinical profile were recorded and compared between patients with initial attack and patients with recurrent attack. A total of 25 patients with ARF were included. There was no different incidence of arthritis and carditis between two groups. Initial attack patients have higher incidence of prolonged PR-interval (67 vs. 12%, P = 0.049) and longer duration of admission to diagnosis (5 vs. 2 days, P = 0.05). Thirty percent presented initial attack after 30 years of age. ARF is more common in adults than previously recognized. Therefore, clinicians should be aware of this condition and include it in their differential diagnosis of the febrile patients with arthritis.

    Acute myocarditis can be induced by various concomitant disease processes including infections. Most of these cases are viral in origin; however, bacterial infections are also implicated to a lesser degree. Group A streptococcus is a frequent culprit in bacterial-induced myocarditis.

    Acute myocarditis can be induced by various concomitant disease processes including infections. Most of these cases are viral in origin; however, bacterial infections are also implicated to a lesser degree. Group A streptococcus is a frequent culprit in bacterial-induced myocarditis.

    OBJECTIVE Coronary CT angiography has high sensitivity, but modest specificity, to detect acute coronary syndrome. We studied whether adding resting CT myocardial perfusion imaging improved the detection of acute coronary syndrome. SUBJECTS AND METHODS Patients with low-to-intermediate cardiac risk presenting with possible acute coronary syndrome received both the standard of care evaluation and a research thoracic 64-MDCT examination. Patients with an obstructive (> 50%) stenosis or a nonevaluable coronary segment on CT were diagnosed with possible acute coronary syndrome. CT perfusion was determined by applying gray and color Hounsfield unit maps to resting CT angiography images. Adjudicated patient diagnoses were based on the standard of care and 3-month follow-up. Patient-level diagnostic performance for acute coronary syndrome was calculated for coronary CT, CT perfusion, and combined techniques. RESULTS A total of 105 patients were enrolled. Of the nine (9%) patients with acute coronary syndrome, all had obstructive CT stenoses but only three had abnormal CT perfusion. CT perfusion was normal in all other patients. To detect acute coronary syndrome, CT angiography had 100% sensitivity, 89% specificity, and a positive predictive value of 45%. For CT perfusion, specificity and positive predictive value were each 100%, and sensitivity was 33%. Combined cardiac CT and CT perfusion had similar specificity but a higher positive predictive value (100%) than did CT angiography. CONCLUSION Resting CT perfusion using CT angiographic images may have high specificity and may improve CT positive predictive value for acute coronary syndrome without added radiation and contrast. However, normal resting CT perfusion cannot exclude acute coronary syndrome. PMID:23617513

    Objectives We sought to describe the demographics, clinical characteristics, management and outcomes of patients in Oman with acute heart failure (AHF) as part of the Gulf aCute heArt failuRe rEgistry (CARE) project. Methods Data were analyzed from 988 consecutive patients admitted with AHF to 12 hospitals in Oman between 14 February and 14 November 2012. Results The mean age of our patients was 63±12 years. Over half (57%) were male and 95% were Omani citizens. Fifty-seven percent of patients presented with acute decompensated chronic heart failure (ADCHF) while 43% had new-onset AHF. The primary comorbid conditions were hypertension (72%), coronary artery disease (55%), and diabetes mellitus (53%). Ischemic heart disease (IHD), hypertensive heart disease, and idiopathic cardiomyopathy were the most common etiologies of AHF in Oman. The median left ventricular ejection fraction of the cohort was 36% (27–45%) with 56% of the patients having heart failure with reduced ejection fraction (< 40%). Atrial fibrillation was seen in 15% of patients. Acute coronary syndrome (ACS) and non-compliance with medications were the most common precipitating factors. At discharge, angiotensin converting enzyme inhibitors and beta-blockers were prescribed adequately, but aldosterone antagonists were under prescribed. Within 12-months follow-up, one in two patients were rehospitalized for AHF. In-hospital mortality was 7.1%, which doubled to 15.7% at three months and reached 26.4% at one-year post discharge. Conclusions Oman CARE was the first prospective multicenter registry of AHF in Oman and showed that heart failure (HF) patients present at a younger age with recurrent ADCHF and HF with reduced ejection fraction. IHD was the most common etiology of HF with a low prevalence of AHF, but a high prevalence of acute coronary syndrome and non-compliance with medications precipitating HF. A quarter of patients died at one-year follow-up even though at discharge medical therapy was

    Aspirin allergy in a patient with acute coronary syndrome represents one of the more urgent challenges an allergist may face. Adverse reactions to aspirin are reported in 1.5% of patients with coronary artery disease. A history of adverse reaction to aspirin often leads to unnecessary withholding of this medication or use of alternative antiplatelet therapy which may be inferior or more costly. Aspirin therapy has been shown to reduce morbidity and mortality in patients with coronary artery disease. Rapid aspirin challenge/desensitization in the aspirin allergic patient has been consistently shown to be both safe and successful in patients with acute coronary syndromes.

    In this article, the novel ( G '/ G)-expansion method is successfully applied to construct the abundant travelling wave solutions to the KdV-mKdV equation with the aid of symbolic computation. This equation is one of the most popular equation in soliton physics and appear in many practical scenarios like thermal pulse, wave propagation of bound particle, etc. The method is reliable and useful, and gives more general exact travelling wave solutions than the existing methods. The solutions obtained are in the form of hyperbolic, trigonometric and rational functions including solitary, singular and periodic solutions which have many potential applications in physical science and engineering. Many of these solutions are new and some have already been constructed. Additionally, the constraint conditions, for the existence of the solutions are also listed.

    It has been found that in 15% of acute myocardial infarction patients' platelets generate reactive oxygen species that can be detected with luminol-enhanced chemiluminescence of platelet-rich plasma within 8-10 days after acute myocardial infarction. This increase in generate reactive oxygen species production coincides with the emergence of CD45(+) platelets. The ability of platelets to carry surface leukocyte antigen implies their participation in exchange of specific proteins in the course of acute myocardial infarction. Future studies of CD45(+) platelets in peripheral blood of acute myocardial infarction patients in association with generate reactive oxygen species production may provide a new insight into the complex mechanisms of cell-cell interactions associated with acute myocardial infarction.

    Conventional markers of kidney function that are familiar to clinicians, including the serum creatinine and blood urea nitrogen levels, are unable to reveal genuine injury to the kidney, and their use may delay treatment. Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine, and the predictive role and pathogenic mechanism of MIF deregulation during kidney infections involving acute kidney injury (AKI) are not currently known. In this study, we showed that elevated urinary MIF levels accompanied the development of AKI during kidney infection in patients with acute pyelonephritis (APN). In addition to the MIF level, the urinary levels of interleukin (IL)-1β and kidney injury molecule (KIM)-1 were also upregulated and were positively correlated with the levels of urinary MIF. An elevated urinary MIF level, along with elevated IL-1β and KIM-1 levels, is speculated to be a potential biomarker for the presence of AKI in APN patients. PMID:23319831

    Subsets of patients with a remote history of Kawasaki disease (KD) have coronary artery aneurysms with associated risks of late morbidity. In a pilot study, we previously showed that computed tomography (CT) coronary artery calcium (CAC) scoring detects late CAC in patients with aneurysms and a remote history of KD. We performed CT calcium volume scoring in 166 subjects (median age 19.5 years) with a remote history of KD (median interval from KD to CT 15.1 years). Coronary arteries were classified as normal (n = 100), transiently dilated (n = 23), persistently dilated (n = 10), remodeled aneurysm (n = 9), or aneurysm (n = 24) based on echocardiography. All subjects with coronary arteries classified as normal, persistently dilated, or remodeled aneurysm had zero CAC. Of the 24 subjects with coronary aneurysms, all but 5 had CAC (median volume 542 mm(3); range 17 to 8,218 mm(3)). For subjects imaged ≥9 years after their acute KD (n = 144), the presence of CAC had a sensitivity of 95% and a specificity of 100% for detecting coronary artery abnormalities (defined as coronary artery aneurysm and/or stenosis). In conclusion, coronary calcification was not observed in subjects with a history of KD who had normal coronary arteries by echocardiography during the acute phase. Coronary calcification, which may be severe, occurs late in patients with coronary aneurysms. Therefore, CAC scanning may be a useful tool to screen patients with a remote history of KD or suspected KD and unknown coronary artery status.

    Seizures may present with ictal or interictal psychosis mimicking primary psychiatric disorders. The authors reviewed EEG, brain-imaging, and clinical data of 240 patients presenting with acute psychotic episode to assess the diagnostic value of EEG in differentiating ictal psychosis from primary psychosis. Seven patients had interictal spikes, but there were no patients with ictal discharges. There were no significant associations between the tested variables except that taking neuroleptics/antidepressants was associated with abnormal EEG, and older age and taking anti-epileptic drugs were associated with abnormal CT scans. These findings do not support routine use of EEG in patients presenting with acute psychosis.

    Patients with a clinical diagnosis of dengue but negative by serological testing were studied for rubella infection. Paired sera were obtained from 69 patients during an outbreak in Yucatán, México. The presence of specific anti-viral IgM in the acute sera was considered as diagnostic for rubella infection. The immunoglobulin was determined by measuring the difference in the inhibition of hemagglutination between the non-reduced and the reduced fractionated sera. Immunoglobulins were separated by sucrose density centrifugation. Acute rubella infection was found in 7 (10.1%) of the patients. These results demonstrate active rubella infection in patients clinically diagnosed as dengue. PMID:2323361

    Earlier intervention in acute HIV infection limits HIV reservoirs and may decrease HIV transmission. We developed criteria for empiric antiretroviral therapy (ART) in an emergency department (ED) routine HIV screening program. We assessed the feasibility and willingness of patients with suspected acute HIV infection in the ED to begin ART. A suspected acute HIV infection was defined as a positive HIV antigen antibody combination immunoassay with pending HIV-antibody differentiation test results and HIV RNA viral load. During the study period, there were 16 confirmed cases of acute HIV infection: 11 met our criteria for empiric ART and agreed to treatment, 10 were prescribed ART, and 1 left the ED against medical advice without a prescription for ART. Eight patients completed at least one follow-up visit. Empiric HIV treatment in an ED is feasible, well received by patients, and offers a unique entry point into the HIV care continuum.

    Within the first week of the disease, acute kidney injury (AKI) is among the most common causes of mortality in acute pancreatitis (AP). Recently, serum angiopoietin-2 (Ang-2) has been associated with hyperdynamic state of the systemic circulation. The aim of this study was to examine the associations between Ang-2 and the clinical AP severity during the first 72 hours of the disease, and organ disfunction, including AKI. Methods. Study included patients admitted to the surgery ward, diagnosed with AP. AKI was diagnosed according to KDIGO guidelines and renal failure according to modified Marshall scoring system. Ang-2 was determined in serum with ELISA. Results. AP was classified as mild (MAP) in 71% of patients, moderately severe (MSAP) in 22%, and severe (SAP) in 8%. During the first 72 hours of AP, 11 patients developed AKI and 6 developed renal failure. Ang-2 at 24, 48, and 72 hours following the onset of AP symptoms significantly predicted SAP and MSAP, as well as AKI and renal failure. Also, Ang-2 significantly correlated with acute phase proteins as well as with the indicators of renal disfunction. Conclusions. Serum Ang-2 may be a relevant predictor of AP severity, in particular of the development of AP-renal syndrome.

    Abstract Evaluation of acute white matter injuries caused by carbon monoxide (CO) poisoning can be limited by conventional magnetic resonance (MR) imaging. We aim to evaluate the feasibility of diffusion kurtosis imaging (DKI) for early detection of white matter alterations in patients with acute CO intoxication. A total of 30 subjects including 15 acute CO patients and 15 age- and sex-matched healthy volunteers were enrolled in this study. MR examinations were performed on a 3T MR scanner within 8 days after CO intoxication. DKI data were acquired to derive axial, radial, and mean kurtosis, as well as fractional anisotropy (FA), axial, radial, and mean diffusivity for tract-specific comparisons between the 2 groups. Significant decreases of mean kurtosis were shown in the genu of corpus callosum, cingulum, and motor-related tracts (corticospinal and corticobulbar tracts) in patients with acute CO intoxication as compared with controls. On the contrary, significant differences of FA values were merely shown in the regions of corticospinal tracts. DKI demonstrated comparably stronger potential than diffusion tensor imaging in terms of early detection of white matter changes in patients with acute CO intoxication. This may have implications in therapeutic strategy for managing acute CO intoxication patients. PMID:28151889

    Background: Patients with chronic obstructive pulmonary disease (COPD) often present with severe acute exacerbations requiring hospital treatment. However, little is known about the prognostic consequences of these exacerbations. A study was undertaken to investigate whether severe acute exacerbations of COPD exert a direct effect on mortality. Methods: Multivariate techniques were used to analyse the prognostic influence of acute exacerbations of COPD treated in hospital (visits to the emergency service and admissions), patient age, smoking, body mass index, co-morbidity, long term oxygen therapy, forced spirometric parameters, and arterial blood gas tensions in a prospective cohort of 304 men with COPD followed up for 5 years. The mean (SD) age of the patients was 71 (9) years and forced expiratory volume in 1 second was 46 (17)%. Results: Only older age (hazard ratio (HR) 5.28, 95% CI 1.75 to 15.93), arterial carbon dioxide tension (HR 1.07, 95% CI 1.02 to 1.12), and acute exacerbations of COPD were found to be independent indicators of a poor prognosis. The patients with the greatest mortality risk were those with three or more acute COPD exacerbations (HR 4.13, 95% CI 1.80 to 9.41). Conclusions: This study shows for the first time that severe acute exacerbations of COPD have an independent negative impact on patient prognosis. Mortality increases with the frequency of severe exacerbations, particularly if these require admission to hospital. PMID:16055622

    Objective The aim of this study was to investigate whether the acute care of frail elderly patients in a comprehensive geriatric assessment (CGA) unit is superior to the care in a conventional acute medical care unit. Design This is a clinical, prospective, randomized, controlled, one-center intervention study. Setting This study was conducted in a large county hospital in western Sweden. Participants The study included 408 frail elderly patients, aged ≥75 years, in need of acute in-hospital treatment. The patients were allocated to the intervention group (n=206) or control group (n=202). Mean age of the patients was 85.7 years, and 56% were female. Intervention This organizational form of care is characterized by a structured, systematic interdisciplinary CGA-based care at an acute elderly care unit. Measurements The primary outcome was the change in health-related quality of life (HRQoL) 3 months after discharge from hospital, measured by the Health Utilities Index-3 (HUI-3). Secondary outcomes were all-cause mortality, rehospitalizations, and hospital care costs. Results After adjustment by regression analysis, patients in the intervention group were less likely to present with decline in HRQoL after 3 months for the following dimensions: vision (odds ratio [OR] =0.33, 95% confidence interval [CI] =0.14–0.79), ambulation (OR =0.19, 95% CI =0.1–0.37), dexterity (OR =0.38, 95% CI =0.19–0.75), emotion (OR =0.43, 95% CI =0.22–0.84), cognition (OR = 0.076, 95% CI =0.033–0.18) and pain (OR =0.28, 95% CI =0.15–0.50). Treatment in a CGA unit was independently associated with lower 3-month mortality adjusted by Cox regression analysis (hazard ratio [HR] =0.55, 95% CI =0.32–0.96), and the two groups did not differ significantly in terms of hospital care costs (P>0.05). Conclusion Patients in an acute CGA unit were less likely to present with decline in HRQoL after 3 months, and the care in a CGA unit was also independently associated with lower mortality

    Acute porphyrias are caused by the inherited decreased activity of the enzymes of the heme biosynthesis pathway. Depending on the affected enzyme there are 4 types of them: acute intermittent porphyria, porphyria variegata, coproporphyria and delta-aminolevulinic acid dehydratase deficient porphyria, listed in order of their frequency. Basically the clinical picture is the same in the four types of acute porphyria. The most frequent complaints and symptoms are: cramping abdominal pain, nausea, vomiting, muscle weakness of the limbs then, in the advanced phase, there is a red-colored urine, hyponatremia, subileus, acute psychosis and Landry-type paralysis. Without proper treatment death is caused by respiratory paralysis or serious arrhythmia. In case of suspicion of acute porphyria it is mandatory to identify the type of the acute porphyria and the actual status of the patient. The later indicates what kind of treatment should be used. In the acute phase the early therapy with heme arginate is the treatment of choice. Since the clinical symptoms are precipitated by endogenous or exogenous inducing factors--most often by drugs-, the drugs negatively affecting the heme biosynthesis should be omitted at once even in the suspicion of acute porphyria. The role of the inducing factors in the manifestation of the clinical symptoms makes possible the prevention. It is possible to avoid the inducing factors and this way to prevent the acute attack if the acute porphyrias are recognized in time and the patients and the carriers are under regular control. The patients receive special identification card and the up-to-date list of safe drugs. They can use only these drugs in any kind of illness. Other drugs should be considered as porphyrinogenic since it is impossible to predict based on their chemical structure if they negatively affect the heme biosynthesis.

    Introduction Hemorrhagic transformation (HT) after acute ischemic stroke (AIS) can be seen at any time following ischemic stroke. Although HT usually occurs as a complication of antithrombotic, anticoagulant, or thrombolytic treatments, it can also occur spontaneously. We aimed to investigate the occurrence of early HT and its relevant risk factors in patients diagnosed with acute middle cerebral artery (MCA) infarction who were not treated with thrombolytic agents. Methods We recruited 171 patients with acute MCA infarction between January 2011 and July 2012 who were not treated with thrombolytic agents and were suitable to our inclusion criteria. Controlled neuroimaging was performed immediately in patients with deterioration, otherwise on day 7 following stroke. All patients were investigated for AIS risk factors and biochemical analyses were performed. Patients with HT in controlled neuroimaging were grouped both clinically (i.e., symptomatic or asymptomatic) and radiologically, according to “European Cooperative Acute Stroke Radiological Study” (ECASS), and risk factors were examined. Results We enrolled 171 patients [94 men (55%) and 77 women (45%)] in the study. HT developed in 37 patients (21.63%). In terms of risk factor analysis, the most frequent etiological factor was atherosclerosis in AIS patients (50.3%). National Institutes of Health Stroke Scale scores were significantly higher both in sHT patients according to asHT patients and in HT patients on day 7 compared with their initial scores. Serum low-density lipoprotein (LDL-C), triglycerides (TG), and total cholesterol (TC) levels were significantly lower in patients with HT (p<.001). Conclusion HT is a major complication in AIS that considerably increases the morbidity and mortality. To reduce the occurrence of HT, risk factors for each patient population should be determined. Acute thrombolytic therapy should be used cautiously in high-risk patients, and appropriate alternative therapies should

    Acute myeloid leukemia originates from leukemia-initiating cells that reside in the protective bone marrow niche. CXCR4/CXCL12 interaction is crucially involved in recruitment and retention of leukemia-initiating cells within this niche. Various drugs targeting this pathway have entered clinical trials. To evaluate CXCR4 imaging in acute myeloid leukemia, we first tested CXCR4 expression in patient-derived primary blasts. Flow cytometry revealed that high blast counts in patients with acute myeloid leukemia correlate with high CXCR4 expression. The wide range of CXCR4 surface expression in patients was reflected in cell lines of acute myeloid leukemia. Next, we evaluated the CXCR4-specific peptide Pentixafor by positron emission tomography imaging in mice harboring CXCR4 positive and CXCR4 negative leukemia xenografts, and in 10 patients with active disease. [(68)Ga]Pentixafor-positron emission tomography showed specific measurable disease in murine CXCR4 positive xenografts, but not when CXCR4 was knocked out with CRISPR/Cas9 gene editing. Five of 10 patients showed tracer uptake correlating well with leukemia infiltration assessed by magnetic resonance imaging. The mean maximal standard uptake value was significantly higher in visually CXCR4 positive patients compared to CXCR4 negative patients. In summary, in vivo molecular CXCR4 imaging by means of positron emission tomography is feasible in acute myeloid leukemia. These data provide a framework for future diagnostic and theranostic approaches targeting the CXCR4/CXCL12-defined leukemia-initiating cell niche.

    Background and Objectives The benefit of early statin treatment following acute myocardial infarction (MI) complicated with cardiogenic shock (CS) has not been well studied. We sought to assess the effect of early statin therapy in patients with CS complicating acute MI. Subjects and Methods We studied 553 statin-naive patients with acute MI and CS (Killip class IV) who underwent revascularization therapy between November 2005 and January 2008 at 51 hospitals in the Korea Acute Myocardial Infarction Registry. Patients were divided into 2 groups: those who received statins during hospitalization (n=280) and those who did not (n=273). The influence of statin treatment on a 12-month clinical outcome was examined using a matched-pairs analysis (n=200 in each group) based on the propensity for receiving statin therapy during hospitalization. Results Before adjustment, patients receiving statin, compared to those not receiving statin, had a more favorable clinical profile, were less likely to suffer procedural complications, and more likely to receive adequate medical therapy. Patients receiving statin had lower unadjusted in-hospital mortality and composite rate of mortality, MI, and repeat revascularization at 12 months, which remained significantly lower after adjustment for patient risk, procedural characteristics, and treatment propensity. Conclusion In CS patients with acute MI undergoing revascularization therapy, early statin treatment initiated during hospitalization was associated with lower rates of in-hospital death and 12-month adverse cardiac events.

    B cell lymphoma protein-2 (Bcl-2) may contribute to the pathophysiology of schizophrenia in the brain. The aim of this study was to investigate the serum levels of Bcl-2 in schizophrenic patients in an acute phase, and evaluate Bcl-2 level changes after antipsychotic treatment. We consecutively enrolled 41 schizophrenia patients in an acute phase; 28 were followed up with a 4-week antipsychotic treatment. Serum Bcl-2 levels were measured with assay kits. All patients were evaluated by examining the correlation between Bcl-2 levels and Positive and Negative Syndrome Scale (PANSS) scores, using Pearson correlation coefficients. In schizophrenic patients in an acute phase, positive PANSS subscores were significantly negatively correlated with Bcl-2 levels. In addition, we found Bcl-2 levels had a significantly negative correlation with PANSS total scores and positive subscores in male patients in an acute phase. Using the paired t-test, we found no significant changes in Bcl-2 levels in schizophrenia patients who had received the 4-week treatment with antipsychotic drugs (n=28). In conclusion, our results suggest that Bcl-2 might be an indicator of schizophrenia severity in the acute phase. In addition, Bcl-2 levels might be associated with positive symptoms in male patients with schizophrenia.

    The role of magnetic resonance imaging in characterizing normal, ischemic and infarcted segments of myocardium was examined in 8 patients with unstable angina, 11 patients with acute myocardial infarction, and 7 patients with stable angina. Eleven normal volunteers were imaged for comparison. Myocardial segments in short axis magnetic resonance images were classified as normal or abnormal on the basis of perfusion changes observed in thallium-201 images in 22 patients and according to the electrocariographic localization of infarction in 4 patients. T2 relaxation time was measured in 57 myocardial segments with abnormal perfusion (24 with reversible and 33 with irreversible perfusion changes) and in 25 normally perfused segments. T2 measurements in normally perfused segments of patients with acute myocardial infarction, unstable angina and stable angina were within normal range derived from T2 measurements in 48 myocardial segments of 11 normal volunteers (42 +/- 10 ms). T2 in abnormal myocardial segments of patients with stable angina also was not significantly different from normal. T2 of abnormal segments in patients with unstable angina (64 +/- 14 in reversibly ischemic and 67 +/- 21 in the irreversibly ischemic segments) was prolonged when compared to normal (p less than 0.0001) and was not significantly different from T2 in abnormal segments of patients with acute myocardial infarction (62 +/- 18 for reversibly and 66 +/- 11 for irreversibly ischemic segments). The data indicate that T2 prolongation is not specific for acute myocardial infarction and may be observed in abnormally perfused segments of patients with unstable angina.

    Patient: Female, 35 Final Diagnosis: Takotsubo cardiomyopathy Symptoms: Seizures Medication: — Clinical Procedure: Cesarean section Specialty: Critical Care Medicine Objective: Rare co-existance of disease or pathology Background: Acute pulmonary edema in a pregnant patient is associated with significant morbidity and mortality. Takotsubo syndrome, or stress-induced cardiomyopathy, is a rare cause of acute pulmonary edema in a pregnant patient, especially prior to delivery of the fetus. Case Report: We describe a case of a pregnant patient who presented with acute pulmonary edema and eclampsia and was found to have Takotsubo syndrome. To the best of our knowledge, eclampsia as a precipitating factor for Takotsubo syndrome has not been described in literature. Conclusions: Clinicians taking care of pregnant patients should be aware of the potential link between eclampsia and Takotsubo cardiomyopathy. Prompt correction of the precipitating cause along with supportive management as described is the key to a successful outcome. PMID:27658947

    In the present paper, a general solution involving three arbitrary functions for the generalized (2+1)-dimensional KdV-mKdV equation, which is derived from the generalized (1+1)-dimensional KdV-mKdV equation, is first introduced by means of the Wiess, Tabor, Carnevale (WTC) truncation method. And then multisymplectic formulations with several conservation laws taken into account are presented for the generalized (2+1)-dimensional KdV-mKdV equation based on the multisymplectic theory of Bridges. Subsequently, in order to simulate the periodic wave solutions in terms of rational functions of the Jacobi elliptic functions derived from the general solution, a semi-implicit multi-symplectic scheme is constructed that is equivalent to the Preissmann scheme. From the results of the numerical experiments, we can conclude that the multi-symplectic schemes can accurately simulate the periodic wave solutions of the generalized (2+1)-dimensional KdV-mKdV equation while preserve approximately the conservation laws.

    A 70-year-old African American female with a past medical history significant for chronic bilateral shoulder pain and reported sickle cell trait presented with acute-onset bilateral thoracolumbar pain radiating to her left arm. Two days after admission, Hematology was consulted for severely worsening microcytic anemia and thrombocytopenia. Examination of the patient’s peripheral blood smear from admission revealed no cell sickling, spherocytes, or schistocytes. Some targeting was noted. A Coombs test was negative. The patient was eventually transferred to the medical intensive care unit in respiratory distress. Hemoglobin electrophoresis confirmed a diagnosis of hemoglobin SC disease. A diagnosis of acute splenic sequestration crisis complicated by acute chest syndrome was crystallized, and red blood cell exchange transfusion was performed. Further research is necessary to fully elucidate the pathophysiology behind acute splenic sequestration crisis, and the role of splenectomy to treat hemoglobin SC disease patients should be better defined.

    Patients with a bipolar disorder and currently experiencing acute mania often require hospitalization. We explored patient problems, desired patient outcomes, and nursing interventions by individually interviewing 22 nurses. Qualitative content analysis gave a top five of patients problems, desired patient outcomes and nursing interventions, identified as most important in the interviews. We then conducted three focus group meetings to gain greater insight into these results. Intensive nursing care is needed, fine-tuning on the patient as a unique person is essential, taking into account the nature and severity of the manic symptoms of the patient.

    The article presents information obtained during the survey in 64 patients with acute hepatitis B. We show that acute hepatitis B in patients with concomitant chronic toxic liver characterized by a marked imbalance of cytokine status due to a lower level of interleukin-2 and a higher content of interleukin-8, the highest levels of nitrite content, spontaneous oxidative modifications of blood proteins and the lowest content of L -arginine in the blood serum in the dynamics of disease compared with patients without this concomitant factor. In the period of convalescence these changes in patients with acute hepatitis B with concomitant chronic toxic liver characterized combined with higher cytolysis of liver cells, often circulating in the blood of HBsAg seroconversion and less frequently with the advent of anti-HBeAg.

    Acute gastric dilation is a rare but recognised complication in patients with bulimia and anorexia following binge episodes owing to decreased bowel motility. We present a rare case of acute gastric dilation secondary to bulimia in an otherwise healthy 18-year-old female patient that resulted in compression and complete occlusion of the abdominal aorta, leading to acute mesenteric and bilateral lower limb ischaemia. This resolved immediately following a laparotomy and gastric decompression. Management of these patients is very challenging owing to the lack of a successful precedent. To our knowledge, such a catastrophic complication has only ever been reported once in the literature and the outcome was fatal. Our case is of additional importance as it offers a successful management strategy for these patients.

    HLA-B27 is a transplantation antigen found in a high proportion of patients with ankylosing spondylitis. Recently, an association has been shown to exist between HLA-B27 and acute uveitis, even in the absence of ankylosing spondylitis. We have examined the HLA antigen profile of 45 patients with acute nongranulomatous anterior uveitis and have confirmed this relation. In addition, using 90mtechnetium stannous pyrophosphate we have been able to demonstrate abnormal bone scan in 19 of 30 patients studied. Such abnormalities are limited to the sacroiliac joints but are otherwise the same as those seen in overt ankylosing spondylitis. Seven of the 19 patients did not have HLA-B27. These factors suggest that acute anterior uveitis may often represent a manifestation of a spondylitic diathesis even in the complete absence of any suggestive symptomatic or radiologic change and, in some cases, even though the antigenic marker HLA-B27 may be absent.

  6. Acute myocardial infarction after heart irradiation in young patients with Hodgkin's disease

    Forty-seven patients younger than 40 years at the time of the diagnosis, and irradiated to the mediastinum for Hodgkin's disease at Turku University Central Hospital from 1977 to 1982, were regularly followed for 56 to 127 months after therapy. Two patients developed an acute myocardial infarction ten and 50 months after cardiac irradiation at the age of only 28 and 24 years, respectively. None of the patients died from lymphoma within five years from the diagnosis, but one of the infarctions was eventually fatal. Since acute myocardial infarction is rare in this age group, the result suggests strongly that prior cardiac irradiation is a risk factor for acute myocardial infarction. The possibility of radiation-induced myocardial infarction should be taken into account both in treatment planning and follow-up of patients with Hodgkin's disease.

  7. Extended duration of thromboprophylaxis in acutely ill medical patients: optimizing therapy?

    PubMed

    Turpie, A G G

    2007-01-01

    Summary. Patients who are hospitalized for an acute medical illness are at risk of venous thromboembolism (VTE). Current evidence-based guidelines recommend prophylaxis with unfractionated heparin or low-molecular-weight heparin in acutely ill medical patients who are admitted to hospital with congestive heart failure, severe respiratory disease, or who are bedridden with an additional VTE risk factor. The need for thromboprophylaxis is therefore clear in this patient population; however, the optimal duration of prophylaxis in these patients is less clear. In patients undergoing orthopedic or cancer surgery, extended-duration prophylaxis has been shown to be superior to placebo. To date, however, no large-scale clinical trials have assessed the benefits of extended-duration prophylaxis in acutely ill medical patients. This review therefore focuses on the VTE risk profile of acutely ill medical patients, examines the currently available literature for evidence of a potential benefit of extended-duration prophylaxis in these patients, and provides a rationale for the testing of such a hypothesis in a randomized clinical trial.

    2016-01-01

    Introduction Cardiovascular and cerebrovascular diseases are leading causes of morbidity and mortality worldwide. Stroke accounts for the second leading cause of death, about 11.13% of total deaths worldwide. Microalbuminuria is known to be associated with increased risk of mortality in ischaemic stroke patients. But there have been no studies to assess whether microalbuminuria affects the early clinical outcome of patients with acute ischaemic stroke. Aim This study aims to investigate whether microalbuminuria affects the early clinical outcome of patients with acute ischaemic stroke. Materials and Methods This is a prospective study of patients with ischaemic stroke (who presented within 24 hours of symptom onset) who were consecutively admitted in three tertiary care centres during the time period from November 2013 to June 2015. Early clinical outcomes in patients were assessed by investigating the presence of Early Neurological Deterioration (END) using the National Institute of Health Stroke Scale. Urine albumin creatinine ratio was divided into two categories – Normal (less than 30mg/g of creatinine) or Urine Microalbuminuria (30-300 mg/g of creatinine). Results Total 42 out of 70 patients (60%) were found to have microalbuminuria. In multivariate logistic regression analysis, microalbuminuria was found to be independently associated with END in patients with acute ischaemic stroke (p=0.044). Conclusion In the early periods following acute ischaemic stroke, patients with microalbuminuria have worse clinical outcome. PMID:27790489

    The level of blood plasma selenium was analyzed by microfluorimetric method in in-patients and out-patients with acute coronary syndrome with ST-elevation resulting in acute Q-wave myocardial infarction. 72 patients, 40-75 years old, with acute Q-wave myocardial infarction were followed during a month. The initial decreased concentration of blood plasma selenium was recorded in most patients in the acute period of the myocardial infarction: deficiency of the microelement (< 90 mcg/l) was found in 30 subjects, the critical ranges (< 70 mcg/l) were stated in 33 patients. Just 2 patients had optimal concentration and 7 patients had a suboptimal one (90-114 mcg/l). Blood plasma level of the microelement increased in 2 weeks after myocardial infarction (in subacute stage) but it was still within deficient or critical levels. No difference was detected in selen concentration depending on gender, age, location on myocardial infarction, accompanying diseases, presence of some risk factors (smoking, alcohol abuse, hereditary predisposition to coronary artery disease). At the same time we revealed a significant Spearman rank correlation in patients with Q-wave myocardial infarction between basal level of blood serum selenium on the one hand, and electrocardiography indices (reflecting the rate of myocardial lesion and necrosis), echocardiography. data (which characterize myocardium reparation processes and remodeling), CPK (a prognostic marker of the myocardial necrosis), HDL-cholesterol (lipid profile index), blood potassium level and BMI on the other.

    The present study aimed to evaluate the effectiveness of morphine and meperidine (pethidine) as pain relief in opioid-dependent patients with acute pain. A total of 122 opioid-dependent patients with acute pain were included in the study. Their pain severity was assessed, using visual analog scale (VAS) scores ranging from 0 to 10. The patients randomly received intravenous morphine (up to 0.15 mg/kg) or meperidine (up to 1.5 mg/kg) for pain control by patient control analgesia (PCA) pump. The clinical opioid withdrawal scale (COWS) was employed for the assessment of withdrawal symptoms. The pain relief and the emergence of withdrawal symptoms were measured at 15, 30, and 60 minutes after drug administration. The patients who received morphine reported a better pain control compared to those who received meperidine (mean ± standard deviation [SD] VAS scores 4.11±1.90 vs 5.85±2.08 at the end of the study; P<0.001). On the other hand, the patients who received meperidine indicated prominent withdrawal symptoms (mean ± SD COWS scores 4.80±2.18 vs. 1.98±0.82 at the end of the study; P<0.001). Our findings revealed that morphine can be recommended in acute pain management of opioid-dependent patients. In addition, emergency physicians should ask their patients about any drug dependence before selecting the appropriate drug for their acute pain management. PMID:27621675

    To improve the nursing care quality in acute care hospitals in Taiwan after the 2003 SARS epidemic, the Taipei City Government Department of Health has allocated about US dollars 6 million for nurse aides' salaries and costs for recruitment, training, and administration of this program. Yet, there have been no corresponding changes in payments for nursing services by the National Health Insurance system in Taiwan such as increasing nurse fees for inpatient services. This article examines the roles of nurse aides and family members in providing acute patient care in Taiwan and discusses issues of nursing care quality as related to nurse staffing in acute care hospitals.

    Acute pulmonary toxicity associated with brentuximab appears to be a rare but serious adverse effect that can be potentially fatal. We report the case of a twenty-nine-year-old female with Hodgkin's lymphoma who was treated with brentuximab and later presented with severe acute pulmonary toxicity; she improved after the discontinuation of brentuximab and administration of antibiotics and glucocorticoid therapy. Currently there is very little data in the literature in regard to the clinical manifestations and characteristics of patients taking brentuximab and the potential development of acute severe pulmonary toxicity, as well as the appropriate therapeutic approach, making this particular case of successful treatment and resolution unique.

    Background Red blood cell distribution width (RDW) that describes red blood cell volume heterogeneity is a common laboratory test. Our aim was to focus on the association between RDW and acute pancreatitis associated lung injury (APALI). Methodology A total of 152 acute pancreatitis (AP) patients who conformed to the criteria were included in this study. The demographic data, medical histories and laboratory measures was obtained from each patient on admission, further, the medical histories and biological data were analyzed, retrospectively. Results Increased RDW at admission was observed in patients with APALI compared with the non-APALI groups. Our results exhibited that RDW was an independent risk factor for APALI after adjusting leukocyte, neutrophil percentage, random blood glucose (RBG), total bilirubin (TB) and total bile acid (TBA) (Crude model) (OR=2.671;CI 95% 1.145–6.230; P=0.023), further adjustment based on Crude model for sex and age did not attenuate the significantly high risk of APALI in patients with AP, RWD still remained a roles as an independent risk factor for APALI (OR=2.653;CI95 % 1.123–6.138; P=0.026). Conclusions Our study demonstrate that RDW at admission is associated with APALI and should be considered as an underlying risk factor of APALI. PMID:28352692

    2014-07-01

    Acute coronary syndromes have a wide spectrum of clinical presentations and risk of adverse outcomes. A distinction should be made between treatable (extent of ischemia, severity of coronary disease and acute hemodynamic deterioration) and untreatable risk (advanced age, prior myocardial damage, chronic kidney dysfunction, other comorbidities). Most of the patients with "untreatable" risk have been excluded from the "guideline-generating" clinical trials. In recent years, despite the paucity of specific randomized trials, major advances have been completed in the management of elderly patients and patients with comorbidities: from therapeutic nihilism to careful titration of antithrombotic agents, a shift toward the radial approach to percutaneous coronary interventions, and also to less-invasive cardiac surgery. Further advances should be expected from the development of drug regimens suitable for use in the elderly and in patients with renal dysfunction, from a systematic multidisciplinary approach to the management of patents with diabetes mellitus and anemia, and from the courage to undertake randomized trials involving these high-risk populations.

  18. Patients' age as a determinant of care received following acute stroke: A systematic review

    PubMed Central

    2011-01-01

    Background Evidence-based care should improve acute stroke outcomes with the same magnitude of effect for stroke patients of all ages. However, there is evidence to suggest that, in some instances, older stroke patients may receive poorer quality care than younger patients. Our aim was to systematically review evidence of the quality of care provided to patients with acute stroke related to their age. Quality of care was determined by compliance with recommended care processes. Methods We systematically searched MEDLINE, CINAHL, ISI Web of Knowledge, Ageline and the Cochrane Library databases to identify publications (1995-2009) that reported data on acute stroke care process indicators by patient age. Data extracted included patient demographics and process indicator compliance. Included publications were critically appraised by two independent reviewers using the Critical Appraisal Skills Programme tool, and a comparison was made of the risk of bias according to studies' findings. The evidence base for reported process indicators was determined, and meta-analysis was undertaken for studies with sufficient similarity. Results Nine from 163 potential studies met the inclusion criteria. Of the 56 process indicators reported, eleven indicators were evidence-based. Seven of these indicators (64%) showed significantly poorer care for older patients compared to younger ones, while younger patients received comparatively inferior care for only antihypertensive therapy at discharge. Our findings are limited by the variable methodological quality of included studies. Conclusion Patients' age may be a factor in the care they receive after an acute stroke. However, the possible influence of patients' age on clinicians' decision-making must be considered in terms of the many complex issues that surround the provision of optimal care for older patients with acute stroke.

    The potential for regulating immune function in acute respiratory distress syndrome (ARDS) through enteral-administered anti-inflammatory lipids has generated much interest over the past 20 years. Yet recommendations remain inconclusive regarding the utilization of ω-3 fatty acids in patients with ARDS and acute lung injury (ALI). Studies are limited in number, with differing methods, small sample sizes, and conflicting results, making recommendations difficult to interpret.

  20. Decreasing Kd uncertainties through the application of thermodynamic sorption models.

    Radionuclide retardation processes during transport are expected to play an important role in the safety assessment of subsurface disposal facilities for radioactive waste. The linear distribution coefficient (Kd) is often used to represent radionuclide retention, because analytical solutions to the classic advection-diffusion-retardation equation under simple boundary conditions are readily obtainable, and because numerical implementation of this approach is relatively straightforward. For these reasons, the Kd approach lends itself to probabilistic calculations required by Performance Assessment (PA) calculations. However, it is widely recognised that Kd values derived from laboratory experiments generally have a narrow field of validity, and that the uncertainty of the Kd outside this field increases significantly. Mechanistic multicomponent geochemical simulators can be used to calculate Kd values under a wide range of conditions. This approach is powerful and flexible, but requires expert knowledge on the part of the user. The work presented in this paper aims to develop a simplified approach of estimating Kd values whose level of accuracy would be comparable with those obtained by fully-fledged geochemical simulators. The proposed approach consists of deriving simplified algebraic expressions by combining relevant mass action equations. This approach was applied to three distinct geochemical systems involving surface complexation and ion-exchange processes. Within bounds imposed by model simplifications, the presented approach allows radionuclide Kd values to be estimated as a function of key system-controlling parameters, such as the pH and mineralogy. This approach could be used by PA professionals to assess the impact of key geochemical parameters on the variability of radionuclide Kd values. Moreover, the presented approach could be relatively easily implemented in existing codes to represent the influence of temporal and spatial changes in geochemistry

    This study aimed to identify acute self-limited hepatitis B (ASL-HB) among patients presenting with hepatitis B virus (HBV)-related acute hepatitis. Data were available for 220 patients diagnosed with HBV-related acute hepatitis, of whom 164 had acute hepatitis B (AHB). Of these, 160 were confirmed as ASL-HB: three (1.9%) evolved to chronic hepatitis B and one (0.6%) developed fulminant hepatitis and died. Comparisons were also made between AHB and acute infections with hepatitis A (HA) and hepatitis E (HE) viruses. During the study period, the number of patients with AHB exceeded the sum of those with acute HA and acute HE infections. There was no distinct seasonal peak for AHB infection, whereas both acute HA and acute HE infections occurred more frequently in the spring. Clinical symptoms and physical signs were similar for all three types of hepatitis, but significant differences were seen in some biochemical parameters. In conclusion, this study suggests that symptomatic AHB is not rare in China but it seldom evolves to chronic hepatitis B.

    16 patients with acute hepatitis, 18 patients with cirrhosis and a total of 21 volunteers and patients with normal liver function received 7.32 mg/kg hexobarbital by linear intravenous infusion within 60 min. Hexobarbital was determined gaschromatographically in serial blood samples and the hexobarbital-clearance was calculated from the plasma concentration curve versus time. Additional experiments were performed in rats suffering from so called "galactosamine hepatitis". In half of the patients with acute hepatitis a normal hexobarbital clearance could be found. In the other patients this was distinctly reduced but not correlation was found to other liver function tests. Patients with cirrhosis were subdivided into two groups. The patients in group 1 were well compensated. The patients in group 2 had a decompensated state with ascites and oesophageal varices. In nearly all patients with cirrhosis the hexobarbital-clearance was diminished. This was more pronounced in group 2. Ketohexobarbital excretion in healthy subjects was in the range of 40-60% of dose. Patients with acute hepatitis excreted only 10-20% of dose and patients with liver cirrhosis only about 5% of dose. In rats with "galactosamine hepatitis" hexobarbital clearance in vivo was distinctly reduced and this could be explained by diminished microsomal cytochrome p 45- and hexobarbital oxidation rate.

    Pharmocokinetics and metabolism of digoxin and beta-methyldigoxin have been studied in patients with acute hepatits after intravenous administration of both H-labeled glycosides. In contrast to digoxin, the rate of decline of radioactivity after administration of beta-methyldigoxin was significantly retarded in patients with acute hepatitis. The increase in plasma concentration after beta-methyldigoxin to patients with acute hepatitis is probably related to decreased demethylation.

    Coronary artery inflammation and aneurysm formation are the most common complications of Kawasaki disease (KD). Valvulitis and myocarditis are also well described and may lead to valvar regurgitation and left ventricular dysfunction. However, functional changes in the right heart have rarely been reported. We noted several acute KD patients with dilated pulmonary arteries (PA) and thus sought to systematically characterize PA size and right-heart function in an unselected cohort of KD patients cared for at a single clinical center. Clinical, laboratory, and echocardiographic data from 143 acute KD subjects were analyzed. PA dilation was documented in 23 subjects (16.1 %); these subjects had higher median right ventricle myocardial performance index (RV MPI), higher ratio of early tricuspid inflow velocity to tricuspid annular early diastolic velocity (TV E/e'), and lower median TV e' velocity compared to the non-PA dilation group (0.50 vs 0.38 p < 0.01, 4.2 vs 3.6 p < 0.05, and 13.5 vs 15.2 cm/s p < 0.01, respectively). Almost all subjects with PA dilation had improved PA Z-score, RV MPI, and TV E/e' in the subacute phase (p < 0.01). There were no significant differences in indices of left ventricle function between PA dilation group and non-PA dilation group. In summary, PA dilation was documented in 16 % of acute KD subjects. These subjects were more likely to have echocardiographic indices consistent with isolated RV dysfunction that improved in the subacute phase. The long-term consequence of these findings will require longitudinal studies of this patient population.

    Cryptococcal meningoencephalitis (CM) may present as an acute, subacute, or chronic infection. It manifests as a chronic process in over 75 % of cases, but, sometimes, it presents with a more acute onset, mostly in HIV-associated patients. Until now, there has been no study performed on the clinical features of HIV-negative CM patients with acute/subacute onset. We collected 106 HIV-negative patients diagnosed with CM in our hospital during a 15-year period, analyzed their epidemiological and clinical features, as well as the outcomes, and explored the independent prognosis factors and the factors related to the survival time among them. We found that impaired consciousness (23.4 % vs. 3.4 %, p = 0.017) was more common in CM patients with acute/subacute onset, while decreased cerebrospinal fluid (CSF) glucose (51.9 % vs. 75.9 %, p = 0.026) was less common. The ratio of CSF glucose/blood glucose [odds ratio (OR) 0.04, 95 % confidence interval (CI) 0.004-0.262, p = 0.02], impaired consciousness (OR 5.09, 95 % CI 1.477-17.522, p = 0.01), and hospitalization length (OR 0.98, 95 % CI 0.977-0.999, p = 0.04) were indicated to be not only independent prognosis factors in HIV-negative CM patients with acute/subacute onset, but also factors significantly related to the survival time. The results of our study demonstrated that the contact history and potential history risk factors would not affect the onset process of HIV-negative CM patients, and the mortality, hospitalization length, and survival time has not been related to the onset process. However, the ratio of CSF glucose/blood glucose, consciousness level, and hospitalization length of the HIV-negative CM patients with acute/subacute onset should be of greater focus in the clinical work.

    Patients with acute medical illnesses are at increased risk of venous thromboembolism (VTE), a significant cause of morbidity and mortality. Thromboprophylaxis is recommended in these patients but questions remain regarding the optimal duration of therapy. The aim of this study is to determine whether oral rivaroxaban is non-inferior to standard-duration (approximately 10 days) subcutaneous (s.c.) enoxaparin for the prevention of VTE in acutely ill medical patients, and whether extended-duration (approximately 5 weeks) rivaroxaban is superior to standard-duration enoxaparin. Patients aged 40 years or older and hospitalized for various acute medical illnesses with risk factors for VTE randomly receive either s.c. enoxaparin 40 mg once daily (od) for 10 ± 4 days or oral rivaroxaban 10 mg od for 35 ± 4 days. The primary efficacy outcomes are the composite of asymptomatic proximal deep vein thrombosis (DVT), symptomatic DVT, symptomatic non-fatal pulmonary embolism (PE), and VTE-related death up to day 10 + 4 and up to day 35 + 4. The primary safety outcome is the composite of treatment-emergent major bleeding and clinically relevant non-major bleeding. As of July 2010, 8,101 patients from 52 countries have been randomized. These patients have a broad range of medical conditions: approximately one-third were diagnosed with acute heart failure, just under one-third were diagnosed with acute infectious disease, and just under one-quarter were diagnosed with acute respiratory insufficiency. MAGELLAN will determine the efficacy, safety, and pharmacological profile of oral rivaroxaban for the prevention of VTE in a diverse population of medically ill patients and the potential of extended-duration therapy to reduce incidence of VTE.

    Objectives Crowding and limited resources have increased the strain on acute care facilities and emergency departments (EDs) worldwide. These problems are particularly prevalent in developing countries. Discrete event simulation (DES) is a computer-based tool that can be used to estimate how changes to complex healthcare delivery systems, such as EDs, will affect operational performance. Using this modality, our objective was to identify operational interventions that could potentially improve patient throughput of one acute care setting in a developing country. Methods We developed a simulation model of acute care at a district level hospital in Ghana to test the effects of resource-neutral (e.g. modified staff start times and roles) and resource-additional (e.g. increased staff) operational interventions on patient throughput. Previously captured, de-identified time-and-motion data from 487 acute care patients were used to develop and test the model. The primary outcome was the modeled effect of interventions on patient length of stay (LOS). Results The base-case (no change) scenario had a mean LOS of 292 minutes (95% CI 291, 293). In isolation, neither adding staffing, changing staff roles, nor varying shift times affected overall patient LOS. Specifically, adding two registration workers, history takers, and physicians resulted in a 23.8 (95% CI 22.3, 25.3) minute LOS decrease. However, when shift start-times were coordinated with patient arrival patterns, potential mean LOS was decreased by 96 minutes (95% CI 94, 98); and with the simultaneous combination of staff roles (Registration and History-taking) there was an overall mean LOS reduction of 152 minutes (95% CI 150, 154). Conclusions Resource-neutral interventions identified through DES modeling have the potential to improve acute care throughput in this Ghanaian municipal hospital. DES offers another approach to identifying potentially effective interventions to improve patient flow in emergency and acute

    The nursing discipline is vital throughout patients' hospital progression. One of the most critical moments in the hospital stay is the postoperative period. Neurosurgical patients require a high level of nursing care and vigilance and additional postoperative monitoring in intensive care units designed specifically for this demographic. In the postoperative setting, patient care must be transferred from anesthesia to nursing in a manner that is continuous and safe. This article focuses on neurosurgical patients in the postoperative period, the assessment of these patients, and critical care nursing, with emphasis on common issues and interventions for this dynamic patient population.

    Proximal humerus fractures are the third most common fracture in elderly patients. Hemiarthroplasty has been the treatment of choice in patients with bone quality and fracture patterns not amenable to open reduction and internal fixation. Reverse total shoulder arthroplasty is a newer option that appears to be less dependent on tuberosity healing than hemiarthroplasty. The authors hypothesized that reverse total shoulder arthroplasty provides improved functional outcomes compared with hemiarthroplasty for fractures in elderly patients.A retrospective review was performed of all patients treated with arthroplasty for acute proximal humerus fractures in an orthopedic practice using a Current Procedural Terminology code search, patient charts, and radiographs. Validated outcome scores were used to assess satisfaction, function, and general well-being. Twenty-three patients were treated for acute proximal humerus fractures (11 reverse total shoulder arthroplasties and 12 hemiarthroplasties). Three patients were lost to follow-up, and 6 patients were deceased. Mean follow-up was 3.6 years (range, 1.3-8 years). Reverse total shoulder arthroplasty outperformed hemiarthroplasty with regard to forward flexion, American Shoulder and Elbow Society score, University of Pennsylvania shoulder score, and Single Assessment Numerical Evaluation score.Reverse total shoulder arthroplasty is a reliable option for acute, proximal humerus fractures that are not amenable to closed treatment or reconstruction in elderly patients. Improved functional outcomes when compared with hemiarthroplasty must be balanced against the increased cost and limited life expectancy of patients with this injury.

    The aim of the study was to measure the occurrence (prevalence and incidence) of episodes of acute low back pain (definite effect) in a wide sample of health workers assisting disabled patients. A questionnaire was used for the study both of true acute low back pain and of episodes of ingravescent low back pain controlled pharmacologically at the onset. The questionnaire identified overall acute and pharmacologically controlled episodes occurring in the previous 12 months, both in the course of work and over the whole life of the subject. Appropriately trained operators administered the questionnaire to 551 subjects; 481 valid answer cards were obtained from 372 females and 109 males working in medical, orthopaedic and geriatric departments. 75.4% of the sample had high exposure index levels for patient lifting. The prevalence of true acute low back pain was 9% in males and 11% in females referred to the previous 12 months. Taking acute true and pharmacologically controlled low back pain together the prevalences rose to 13.8% for males and 26.9% in females. Data from the reference populations showed that acute low back pain did not exceed 3% on average in the previous year. Since work seniority in the hospital wards was known, the incidences were calculated, giving 7.9% in females and 5.29% in males for acute low back pain, and 19% in females and 3.49% in males for pharmacologically controlled low back pain. Considering the number of episodes in 100 workers/year, acute low back pain alone reached prevalences of 13-14%. This therefore appears to confirm the positive ratio between episodes of low back pain and duties involving assistance to disabled patients.

    Acute acalculous cholecystitis (ACC) is most frequently reported in critically ill patients following sepsis, extensive injury or surgery. It is rather uncommon as a chemotherapy-induced complication, which is usually life-threatening in neutropenic patients subjected to myelosuppressive therapy. A 23-year-old patient with acute lymphoblastic leukemia was subjected to myelosuppressive chemotherapy (cyclophosphamide, cytarabine, pegaspargase). After the first chemotherapy cycle the patient was neutropenic and feverish; she presented with vomiting and pain in the right epigastrium. Ultrasound demonstrated an acalculous gallbladder with wall thickening up to 14 mm. The ACC was diagnosed. Medical therapy included a broad spectrum antibiotic regimen and granulocyte-colony stimulating factors. On the second day after ACC diagnosis the patient's general condition worsened. Laparoscopic cholecystectomy was performed. The resected gallbladder showed no signs of bacterial or leukemic infiltrates. The postoperative course was uneventful. In the management of neutropenic patients with ACC surgical treatment is as important as pharmacological therapy. PMID:25337176

    Noroviruses are the leading cause of epidemic gastroenteritis, including foodborne outbreak, in Korea. The prevalence of human noroviruses was studied in diarrheal stool samples of patients with acute gastroenteritis by conventional duplex reverse transcription (RT)-PCR. Diarrheal stool samples were collected from 1,685 patients from the local hospitals in Seoul. The prevalence of the noroviruses was 22.8% (222/972 patients) in 2012 and 11.2% (80/713 patients) in 2013, with a total of 17.9% (302/1,685 patients). Genotyping was performed on 302 norovirus-positive stool samples to reveal 5.6% prevalence of genogroup I (GI) (17/302) and 94.4% prevalence of genogroup II (GII) (285/302). The patients with norovirus-associated acute gastroenteritis mostly showed prevalence of GII norovirus, especially GII.4 (64.6%; 195/302).

    Background This study aimed to determine the effects of smoke bomb-induced acute inhalation injury on pulmonary function at different stages of lung injury. Methods We performed pulmonary function tests (PFTs) in 15 patients with acute inhalation injury from days 3 to 180 after smoke inhalation. We measured the trace element zinc in whole blood on days 4 and 17, and correlations of zinc levels with PFTs were performed. Results In the acute stage of lung injury (day 3), 3 of 11 patients with mild symptoms had normal pulmonary function and 8 patients with restrictive ventilatory dysfunction and reduced diffusing capacity. Some patients also had mild obstructive ventilatory dysfunction (5 patients) and a decline in small airway function (6 patients). For patients with severe symptoms, PFT results showed moderate to severe restrictive ventilatory dysfunction and reduced diffusing capacity. PaCO2 was significantly higher (P=0.047) in patients with reduced small airway function compared with those with normal small airway function. Whole blood zinc levels in the convalescence stage (day 17) were significantly lower than those in the acute stage (day 4). Zinc in the acute stage was negatively correlated with DLCO/VA on days 3, 10, and 46 (r=−0.633, −0.676, and −0.675 respectively, P<0.05). Conclusions Smoke inhalation injury mainly causes restrictive ventilatory dysfunction and reduced diffusing capacity, and causes mild obstructive ventilatory dysfunction and small airway function decline in some patients. Zinc is negatively correlated with DLCO/VA. Zinc levels may be able to predict prognosis and indicate the degree of lung injury. PMID:28066595

    BACKGROUND: Although an autoimmune mechanism has been postulated for myocarditis and acute-onset inflammatory dilated cardiomyopathy (DCM), immunomodulatory treatment strategies are still under investigation. METHODS AND RESULTS: The clinical data of six patients with acute inflammatory DCM referred for evaluation for possible heart transplantation were reviewed. All patients were admitted with acute congestive heart failure and severely impaired left ventricular (LV) function and were treated with high-dose (2 g/kg) intravenous immunoglobulin (IVIG). The diagnosis of acute inflammatory DCM was based on recent onset of congestive heart failure (New York Heart Association functional class III or IV) with severely depressed LV ejection fraction ([LVEF] 30% or lower) occurring shortly after viral-like illness. All patients had inflammation on endomyocardial biopsy or elevated cardiac enzymes, as well as a normal coronary angiogram. All patients were in New York Heart Association class I or II at the time of hospital discharge. The mean LVEF improved from 21.7±7.5% at baseline to 50.3±8.6% at discharge (P=0.005). Four patients had complete recovery (LVEF 50% or higher) and two patients had partial LV recovery. Patients were followed for a median 13.2 months (range two to 24 months) and had a mean LVEF of 53±6% (P not significant versus LVEF at discharge). CONCLUSIONS: Therapy with intravenous high-dose IVIG may be a potentially useful treatment in selected patients if given early in the course of acute fulminant inflammatory DCM. A randomized, prospective trial is warranted to prove the real benefit of IVIG in this patient population. PMID:18612500

    Acute stroke patients with dysphagia are at increased risk for poor hydration. Dysphagia management practices may directly impact hydration status. This study examined clinical factors that might impact hydration status in acute ischemic stroke patients with dysphagia. A retrospective chart review was completed on 67 ischemic stroke patients who participated in a prior study of nutrition and hydration status during acute care. Prior results indicated that patients with dysphagia demonstrated elevated BUN/Cr compared to non-dysphagia cases during acute care and that BUN/Cr increased selectively in dysphagic patients. This chart review evaluated clinical variables potentially impacting hydration status: diuretics, parenteral fluids, tube feeding, oral diet, and nonoral (NPO) status. Exposure to any variable and number of days of exposure to each variable were examined. Dysphagia cases demonstrated significantly more NPO days, tube fed days, and parenteral fluid days, but not oral fed days, or days on diuretics. BUN/Cr values at discharge were not associated with NPO days, parenteral fluid days, oral fed days, or days on diuretics. Patients on modified solid diets had significantly higher mean BUN/Cr values at discharge (27.12 vs. 17.23) as did tube fed patients (28.94 vs. 18.66). No difference was noted between these subgroups at baseline (regular diet vs. modified solids diets). Any modification of solid diets (31.11 vs. 17.23) or thickened liquids (28.50 vs. 17.81) resulted in significantly elevated BUN/Cr values at discharge. Liquid or diet modifications prescribed for acute stroke patients with dysphagia may impair hydration status in these patients.

    BACKGROUND: Glycosylated hemoglobin (HbA1c) level on admission is a prognostic factor for mortality in patients with and without diabetes after myocardial infarction. In the present study, the authors examined the relationship between admission HbA1c level and myocardial perfusion abnormalities in patients with acute myocardial infarction. METHODS: One hundred consecutive patients with acute myocardial infarction who were treated with thrombolytic therapy were included in the present prospective study. Blood glucose and HbA1c levels of all patients were measured within 3 h of admission. Patients were divided into three groups according to HbA1c level: 4.5% to 6.4% (n=25), 6.5% to 8.5% (n=28) and higher than 8.5% (n=47). All patients then underwent exercise thallium-201 imaging and coronary angiography to determine ischemic scores and the number of diseased coronary arteries four weeks after admission. RESULTS: Seven patients died within the four-week follow-up period. There was a significant relationship between admission HbA1c level and mortality (P=0.009). Furthermore, there was a significant relationship between HbA1c level and total ischemic scores in patients with acute myocardial infarction (r=0.482; P=0.001). Ischemic scores increased as HbA1c levels increased in patients with acute myocardial infarction. CONCLUSIONS: The results demonstrated that admission plasma glucose and HbA1c levels are prognostic factors associated with mortality after acute myocardial infarction. PMID:18464942

    The purpose of this consensus document was to reach an agreement among experts on the multidisciplinary care of patients with acute heart failure. Starting with a narrative review of the care provided to these patients and a critical analysis of the healthcare procedures, we identified potential shortcomings and improvements and formalised a document on recommendations for optimising the clinical and therapeutic approach for acute heart failure. This document was validated through an in-person group session guided using participatory techniques. The process resulted in a set of 36 recommendations formulated by experts of the Spanish Society of Cardiology, the Spanish Society of Internal Medicine and the Spanish Society of Urgent and Emergency Care. The recommendations are designed to optimise the healthcare challenge presented by the care of patients with acute heart failure in the context of Spain's current National Health System.

    PubMed Central

    2016-01-01

    Spinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal vascular malformations. However, SDAVFs are still underdiagnosed entities because their clinical symptoms are usually non-specific, as they include low back pain or radiating pain to the limb. There have been several reports of acute paraplegia after lumbar epidural steroid injections in patients with SDAVFs. We present 4 patients with SDAVFs who received lumbar steroid injection. Among the 4 cases, acute paraplegia developed in 2 cases that received a larger volume of injectate than the other cases. Thus, we are suggesting that the volume of injectate may be a contributing factor for acute paraplegia after lumbar steroid injection in patients with SDAVFs. PMID:27847727

    Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup. Appendicitis and complicated biliary pathology are the most frequent causes of non-obstetric acute abdomen in the pregnant patient. The decision to operate, the timing, and the surgical approach are essential for a correct management of this pathology. The aim of this paper is to perform a review and update on the diagnosis and treatment of non-obstetric acute abdomen in pregnancy.

    Therapy-related acute myeloid leukemia (t-AML) is a rare and almost always fatal late side effect of antineoplastic treatment involving chemotherapy, radiotherapy or the two combined. The present retrospective study intended to characterize t-AML patients that were diagnosed and treated in a single referral to an oncological institution in North Portugal. Over the past 10 years, 231 cases of AML were diagnosed and treated at the Portuguese Institute of Oncology of Porto, of which 38 t-AML cases were identified. Data regarding the patient demographics, primary diagnosis and treatment, age at onset of therapy-related myeloid neoplasm, latency time of the neoplasm, cytogenetic characteristics, AML therapy and outcome were collected from medical records. A previous diagnosis with solid tumors was present in 28 patients, and 10 patients possessed a history of hematological conditions, all a lymphoproliferative disorder. Breast cancer was the most frequent solid tumor identified (39.5% of all solid tumors diagnosed). The mean latency time was 3 years. In the present study, t-AML patients were older (P<0.001) and more frequently carried cytogenetic abnormalities (P=0.009) compared with de novo AML patients. The overall survival time was observed to be significantly poorer among individuals with t-AML (P<0.001). However, in younger patients (age, <50 years) there was no difference between the overall survival time of patients with t-AML and those with de novo AML (P=0.983). Additionally, patients with promyelocytic leukemia possess a good prognosis, even when AML occurs as a secondary event (P=0.98). To the best of our knowledge, the present study is the first to evaluate t-AML in Portugal and the results are consistent with the data published previously in other populations. The present study concludes that although t-AML demonstrates a poor prognosis, this is not observed among younger patients or promyelocytic leukemia patients. PMID:27347135

    Statins are commonly used drugs in patients with liver and cardiac disease. Statin-induced severe myopathy is a very uncommon presentation and rhabdomyolysis may occur in extreme cases which leads to renal failure. Patients with comorbidities like diabetes, hypothyroidism, and liver disease have higher chances of development of statin-induced myopathy. We describe a case of Child's C cirrhosis wherein the patient had acute onset significant muscle weakness and improved on statin discontinuation.

    We report a case of acute renal failure related to rhabdomyolysis in a patient with Sheehan syndrome, while other diseases that could cause rhabdomyolysis were excluded. The patient's kidney function completely recovered with 3 sessions of intermittent hemodialysis. After thyroxine replacement therapy, musculoskeletal symptoms disappeared and creatine kinase concentrations decreased. Steroid replacement therapy was also administered. The present case suggests that rhabdomyolysis could occur in a patient with Sheehan syndrome without other precipitating factors.

    Let KdV stand for the Nth Gelfand-Dickey reduction of the KP hierarchy. The purpose of this Letter is to show that and KdV solution leads effectively to a solution of the q-approximation of KdV. Two different q-KdV approximations were proposed, first one by Frenkel [Int. Math. Res. Notices 2 (1996) 55] and a variation by Khesin, Lyubashenko and Roger [J. Func. Anal. 143 (1997) 55]. We show there is a dictionary between the solutions of q-KP and the 1-Toda lattice equations, obeying some special requirement; this is based on an algebra isomorphism between difference operators and D-operators, where Df( x) = f( qx). Therefore every notion about the 1-Toda lattice can be transcribed into q-language.

    Background Patients with Chronic Obstructive Pulmonary Disease (COPD) are frequently hospitalized with an acute exacerbation. Patients with COPD often lose weight. Consequently, deterioration in nutritional status (loss of lean body mass) is a likely repercussion of acute exacerbation in hospitalized COPD patients. The study was carried out to assess the nutritional status of COPD patients with acute exacerbation, during the period of hospital admission, and to evaluate the relationships between the nutritional indices and the pulmonary function parameters. Methods A cross sectional observation study constituting 83 COPD patients consecutively hospitalized with acute exacerbation on accrual during a period of one year. Lung function was measured by routine spirometry. Nutritional status was assessed by the measurement of anthropometric parameters. Hospital outcome was also assessed. Statistical analysis was performed using SPSS version 16.0 Independent t-tests and Pearsons correlation coefficient was used. Results Mean body weight was 50.03 ± 9.23 kg. Subjects had approximately 5 kg weight loss in previous six months. All the subjects had low BMI (19.38 ± 3.10) and MUAC (21.18 ± 2.31) that was significantly below the predicted levels. The correlation between body weight and FEV1/FVC% was good (r = 0.648, p = 0.003). BMI was negatively correlated (r = - 0.0103, p= 0.03) with duration of hospital stay. Conclusions The high prevalence of malnutrition among hospitalized COPD patients with acute exacerbation is related to their lung function and hospital outcome such as duration of hospital stay.

    After i.v. application of 3h-digoxin or 3H-methyldigoxin to 5 healthy volunteers and 5 patients with acute hepatitis, respectively (0.75 mg daily for 3 days and 0.375 for the following 2 days) total radioactivity in urine and plasma were determined. Chloroform-soluble and -insoluble glycosides were separated and the chloroform-soluble fraction was determined by TLC. 3 days after methyldigoxin application plasma levels reached toxic values in the patient group (2.73 +/- 0.48 ng/ml), whereas in patients receiving digoxin a mean plasma level of 0.91 +/- 0.21 ng/ml was obtained. During the first 24 hours following administration of digoxin 44 +/- 12% of the dose were recovered in urine of control subjects and 48 +/- 13% in patients with acute hepatitis, after methyldigoxin 34 +/- 5% and 34 +/- 8%, respectively. Metabolism of digoxin in patients with acute hepatitis was unaltered, whereas a diminished demethylation rate of methyldigoxin could be observed. 16 patients with acute hepatitis and 7 healthy volunteers received unlabelled digoxin p.o. as maintenance dose. Plasma glycoside concentrations were studied by radioimmunoassay. The average glycoside plasma concentrations were 0.59 +/- 0.21 ng/ml and 0.63 +/- 0.24 ng/ml, respectively.

    There is disagreement among psychiatric professionals about whether the doors of acute psychiatric wards should be kept locked to prevent patients from leaving and harming themselves or others. This study explored patient, staff, and visitor perceptions about the acceptability of locking the ward door on acute psychiatric inpatient wards. Interviews were conducted with 14 registered nurses, 15 patients, and six visitors from three different acute wards. Findings revealed commonalities across all groups, with general agreement that locking the door reduced absconding. Staff expressed feelings of guilt, embarrassment, and fear of being blamed when a patient absconded. Staff also reported that open wards created anxious vigilance to prevent an abscond and increased workload in allocating staff to watch the door, whereas staff on partially-locked doors also perceived an increased workload in letting people in and out of the ward. Patients had mixed feelings about the status of the door, expressing depression, a sense of stigma, and low self-esteem when the door was locked. The issue of balancing safety and security on acute psychiatric wards against the autonomy of patients is not easily resolved, and requires focused research to develop innovative nursing practices.

  11. Why are patients with acute stroke admitted to hospital?

    Data on 515 consecutive patients registered with the Oxfordshire Community Stroke Project were used to compare the characteristics of those patients who were admitted to hospital within one month after their first stroke with those who remained in the community during that time. Twenty eight patients had their stroke while in hospital for other conditions, and of the remaining 487, 266 were admitted. Though patients with a severe neurological deficit were significantly more likely to be admitted, 47 out of 202 such patients were managed in the community. In a substudy of 162 consecutive patients the general practitioners' reasons for either arranging admission to hospital or continuing with community care in the first week after the stroke were ascertained. Sixty patients were admitted. The only reason for admission was diagnostic uncertainty in five cases (though this was a contributing factor in 25) and to provide nursing or general, non-medical care in 25. Patients who lived alone were more likely to be admitted. All 12 patients who presented directly to the casualty department were admitted, though only five had had a severe stroke. A stroke service that provides a facility for rapid outpatient and domiciliary diagnosis as well as a rapidly acting domiciliary nursing team might reduce the number of patients with stroke admitted to hospital without adversely affecting the quality of patient care: this should be properly evaluated.

    Summary Background Although the use of magnetic resonance imaging (MRI) for the diagnosis of acute stroke is increasing, this method has not proved more effective than computed tomography (CT) in the emergency setting. We aimed to prospectively compare CT and MRI for emergency diagnosis of acute stroke. Methods We did a single-centre, prospective, blind comparison of non-contrast CT and MRI (with diffusion-weighted and susceptibility weighted images) in a consecutive series of patients referred for emergency assessment of suspected acute stroke. Scans were independently interpreted by four experts, who were unaware of clinical information, MRI-CT pairings, and follow-up imaging. Results 356 patients, 217 of whom had a final clinical diagnosis of acute stroke, were assessed. MRI detected acute stroke (ischaemic or haemorrhagic), acute ischaemic stroke, and chronic haemorrhage more frequently than did CT (p<0.0001, for all comparisons). MRI was similar to CT for the detection of acute intracranial haemorrhage. MRI detected acute ischaemic stroke in 164 of 356 patients (46%; 95% CI 41-51%), compared with CT in 35 of 356 patients (10%; 7-14%). In the subset of patients scanned within 3 h of symptom onset, MRI detected acute ischaemic stroke in 41 of 90 patients (46%; 35-56%); CT in 6 of 90 (7%; 3-14%). Relative to the final clinical diagnosis, MRI had a sensitivity of 83% (181 of 217; 78-88%) and CT of 26% (56 of 217; 20-32%) for the diagnosis of any acute stroke. Interpretation MRI is better than CT for detection of acute ischaemia, and can detect acute and chronic haemorrhage; therefore it should be the preferred test for accurate diagnosis of patients with suspected acute stroke. Because our patient sample encompassed the range of disease that is likely to be encountered in emergency cases of suspected stroke, our results are directly applicable to clinical practice.

    Coronary aneurysms occur in 25% of untreated Kawasaki Disease (KD) patients and put patients at increased risk for myocardial infarction and sudden death. Clinical guidelines recommend using aneurysm diameter >8 mm as the arbitrary criterion for treating with anti-coagulation therapy. This study uses patient-specific modeling to non-invasively determine hemodynamic parameters and quantify thrombotic risk. Anatomic models were constructed from CT angiographic image data from 5 KD aneurysm patients and one normal control. CFD simulations were performed to obtain hemodynamic data including WSS and particle residence times (PRT). Thrombosis was clinically observed in 4/9 aneurysmal coronaries. Thrombosed vessels required twice as many cardiac cycles (mean 8.2 vs. 4.2) for particles to exit, and had lower mean WSS (1.3 compared to 2.8 dynes/cm2) compared to vessels with non-thrombosed aneurysms of similar max diameter. 1 KD patient in the cohort with acute thrombosis had diameter < 8 mm. Regions of low WSS and high PRT predicted by simulations correlated with regions of subsequent thrombus formation. Thrombotic risk stratification for KD aneurysms may be improved by incorporating both hemodynamic and geometric quantities. Current clinical guidelines to assess patient risk based only on aneurysm diameter may be misleading. Further prospective study is warranted to evaluate the utility of patient-specific modeling in risk stratifying KD patients with coronary aneurysms. NIH R21.

    Introduction: It is known that cytomegalovirus (CMV) infection is a common problem among kidney transplant patients. This infection can be increased morbidity and decreased graft survival. This problem has been associated with acute rejection too. Patients and Methods: One hundred and thirty renal transplant patients were included in a prospective, case-control study. The renal transplant patients were divided into two groups; patients group with CMV infection and control group without CMV infection. Serum CMV-IgG in all patients was positive (donor and recipients). None of patients had received anti-thymocyte-globulin and thymoglobulin. CMV infection was diagnosed by quantitative CMV-PCR (polymerase chain reaction) test (more than 500 copies/μg). Rejection episode was defined by kidney isotope scan or biopsy. Results: In the group of 66 CMV infection patients (41 male [62.1%] and 25 female [37.9%]) the incidence of graft rejection was 36%, however in the group of 64 control patients the incidence of graft rejection was 9.4 % (P < 0.005). Conclusion: CMV infection is important predisposing factor for acute allograft rejection after kidney transplantation. The results of this study suggests that the control of CMV infection could decrease episodes of acute kidney rejection. PMID:27471740

    Objective This study aimed to describe and compare the characteristics and clinical outcomes of patients with septic and non-septic acute kidney injury. Methods This study evaluated an open cohort of 117 critically ill patients with acute kidney injury who were consecutively admitted to an intensive care unit, excluding patients with a history of advanced-stage chronic kidney disease, kidney transplantation, hospitalization or death in a period shorter than 24 hours. The presence of sepsis and in-hospital death were the exposure and primary variables in this study, respectively. A confounding analysis was performed using logistic regression. Results No significant differences were found between the mean ages of the groups with septic and non-septic acute kidney injury [65.30±21.27 years versus 66.35±12.82 years, respectively; p=0.75]. In the septic and non-septic acute kidney injury groups, a predominance of females (57.4% versus 52.4%, respectively; p=0.49) and Afro-descendants (81.5% versus 76.2%, respectively; p=0.49) was observed. Compared with the non-septic patients, the patients with sepsis had a higher mean Acute Physiology and Chronic Health Evaluation II score [21.73±7.26 versus 15.75±5.98; p<0.001)] and a higher mean water balance (p=0.001). Arterial hypertension (p=0.01) and heart failure (p<0.001) were more common in the non-septic patients. Septic acute kidney injury was associated with a greater number of patients who required dialysis (p=0.001) and a greater number of deaths (p<0.001); however, renal function recovery was more common in this group (p=0.01). Sepsis (OR: 3.88; 95%CI: 1.51-10.00) and an Acute Physiology and Chronic Health Evaluation II score >18.5 (OR: 9.77; 95%CI: 3.73-25.58) were associated with death in the multivariate analysis. Conclusion Sepsis was an independent predictor of death. Significant differences were found between the characteristics and clinical outcomes of patients with septic versus non-septic acute kidney

    Acute passive fixation atrial lead dislodgment occurred due to an unexpected and marked postural descent of the heart after permanent pacemaker implantation in two patients. Sagging of the heart in these two individuals may have been related to a history of morbid obesity followed by weight loss of over 100 pounds. Lead replacement with active fixation leads was required in both cases. The term "sagging heart syndrome" is proposed to describe this clinical entity. In certain adult populations, such as in patients with a history of significant weight loss, the "sagging heart syndrome" may represent a previously unrecognized cause of acute lead dislodgment.

    We present a case of acute hemolytic anemia, renal failure, and Clostridium perfringens bacteremia in a patient with acute myelogenous leukemia. The high fatality of C. perfringens bacteremia requires that clinicians recognize and rapidly treat patients at risk for this infection. Although other hemolytic processes are in the differential diagnosis of these events, the presence of high fever, chills, and rapidly positive blood cultures may help narrow the diagnosis. Most cases of C. perfringens bacteremia have a concomitant coinfection, which makes broad spectrum empiric therapy essential. There is a high mortality rate of C. perfringens infections associated with leukemia. PMID:27774325

    The objectives of this review were (1) to review recent literature on the rates, risk factors, and outcomes of infections in patients who had chronic kidney disease (CKD) and did or did not require renal replacement therapy; (2) to review literature on the efficacy and use of selected vaccines for patients with CKD; and (3) to outline a research framework for examining key issues regarding infections in patients with CKD. Infection-related hospitalizations contribute substantially to excess morbidity and mortality in patients with ESRD, and infection is the second leading cause of death in this population. Patients who have CKD and do not require renal replacement therapy seem to be at higher risk for infection compared with patients without CKD; however, data about patients who have CKD and do not require dialysis therapy are very limited. Numerous factors potentially predispose patients with CKD to infection: advanced age, presence of coexisting illnesses, vaccine hyporesponsiveness, immunosuppressive therapy, uremia, dialysis access, and the dialysis procedure. Targeted vaccination seems to have variable efficacy in the setting of CKD and is generally underused in this population. In conclusion, infection is a primary issue when caring for patients who receive maintenance dialysis. Very limited data exist about the rates, risk factors, and outcomes of infection in patients who have CKD and do not require dialysis. Future research is needed to delineate accurately the epidemiology of infections in these populations and to develop effective preventive strategies across the spectrum of CKD severity.

    Fasting serum triglycerides were measured in 52 patients who had sustained an attack of pancreatitis (gall stone related 33, alcoholism six) at least six months earlier. Several patients (23%) had raised fasting serum triglycerides, with a type IV phenotype in all but one patient. The 40 patients with normal fasting serum triglycerides received an oral load of 100 g sunflower oil to compare their clearance of dietary triglycerides with that of a control group of 54 subjects. The clearance of ingested triglycerides was significantly impaired in the patients - irrespective of the presumed aetiological factor, or clinical condition associated with pancreatitis - compared with the clearance in controls. A triglyceride tolerance test is the only way to detect those patients in whom a future attack of pancreatitis may be precipitated by a diet rich in fat, or endogenous over production of triglycerides as after an alcoholic debauch.

    Many current mobile health applications ("apps") and most previous research have been directed at management of chronic illnesses. However, little is known about patient preferences and design considerations for apps intended to help in a post-acute setting. Our team is developing an mHealth platform to engage patients in wound tracking to identify and manage surgical site infections (SSI) after hospital discharge. Post-discharge SSIs are a major source of morbidity and expense, and occur at a critical care transition when patients are physically and emotionally stressed. Through interviews with surgical patients who experienced SSI, we derived design considerations for such a post-acute care app. Key design qualities include: meeting basic accessibility, usability and security needs; encouraging patient-centeredness; facilitating better, more predictable communication; and supporting personalized management by providers. We illustrate our application of these guiding design considerations and propose a new framework for mHealth design based on illness duration and intensity.

    The results of study on evaluation of efficacy of combined treatment of patients with acute prostatitis are presented. The study included 34 patients with acute prostatitis aged 19 to 51 years. 13 patients in Group 1 received only basic therapy: fluoroquinolones (ciprofloxacin, 500 mg 2 times daily for 14 days), non-steroidal anti-inflammatory drugs (suppositories voltaren 50 mg at bedtime for 7 days). Along with basic treatments, 21 patients in the Group 2 received phytopreparation prostagutt forte (at a dose 280 mg 2 times a day), which has antiestrogenic, antiproliferative, antiinflammatory, immunomodulatory properties. It was shown that patients receiving prostagutt forte experienced pronounced and significant decrease of white blood count in the prostatic secretion, the decrease of prostate volume according to the data of transrectal ultrasound examination, more rapid relief of the inflammatory process, which was manifested by reduction of hyperthermia and reduction of severity of bladder outlet obstruction associated with swelling of the prostate.

    Objectives Several publications have demonstrated increased 30-day mortality in patients admitted on Saturdays or Sundays compared with weekdays. We sought to determine whether this was true for two different cohorts of patients admitted with acute myocardial infarction (MI). Methods and results Thirty-day mortality data were obtained for 3757 patients who had been admitted to the Belfast Health and Social Care Trust with acute MI between 2009 and 2015. They were subdivided into those presenting with ST elevation MI (n=2240) and non-ST elevation MI (n= 1517). We observed no excess 30-day mortality in those admitted over weekends. Conclusion Excess mortality in patients admitted at weekends is not a universal finding. This may mean that that there are patient subgroups with proportionately greater weekend hazard and points to the need for more detailed understanding of the weekend effect.

We report a nitrate-free patient with a history of cardiovascular risk factors who developed acute MI after taking sildenafil. A 44-year-old man diagnosed with acute anterior ST segment elevation MI 120 min after self-administration of 150 mg sildenafil was admitted before attempting any sexual intercourse. The coronary angiography revealed 99% occlusion of the left anterior descending artery (LAD) and a bare-metal stent was implanted. He was discharged after 5 days without any complication. Sildenafil may cause coronary steal or may lead to vasodilation causing hypotension in patient with pre-existing cardiovascular disease, especially in patients on nitrate therapy. Our patient was nitrate free, with normal blood pressure values. Emotional stimulation associated with anticipated sexual activity may have been a triggering factor for vulnerable coronary plaque rupture.

    Low back pain has a life time prevalence of 70% to 85%. Approximately 10% to 20% of all patients experience recurrent episodes or develop chronic low back pain. Sociodemographic, clinical, and psychological characteristics explain the transition from acute to chronic low back pain only to a limited extent. Altered central pain processing may be a contributing mechanism. The measurement of reflex receptive fields (RRF) is a novel method to assess altered central pain processing. The RRF area denotes the area of the foot sole from which spinal nociceptive reflexes can be elicited. It was shown to be enlarged in patients with acute and chronic low back pain compared with pain-free individuals. The aim of the study was to explore the discriminative ability of the RRF to distinguish patients with acute and chronic low back pain with the hypothesis that enlarged RRF are associated with chronic low back pain. We included 214 patients with either acute or chronic low back pain and compared RRF between groups in both univariable and multivariable analyses adjusted for different sociodemographic and clinical characteristics possibly associated with the transition to chronic pain. We found a mean difference between patients with acute and chronic low back pain of -0.01 (95% confidence interval [CI], -0.06 to 0.04) in the crude, -0.02 (95% CI, -0.08 to 0.04) in the age and sex adjusted, and -0.02 (95% CI, -0.09 to 0.05) in the fully adjusted model. Our results suggest that the enlargement of RRF area may not be associated with the transition from acute to chronic low back pain.

    For patients with a non-ST-segment elevation acute coronary syndrome (NSTE-ACS), guideline recommendations and treatment pathways focus on revascularization for definitive treatment if the patient is an appropriate candidate. Despite the widespread use of revascularization for NSTE-ACS, most patients undergo a percutaneous coronary intervention, whereas a minority of patients undergo coronary artery bypass grafting. Focusing specifically on the USA, the contemporary utilization, preoperative and perioperative considerations, and outcomes of NSTE-ACS patients undergoing coronary artery bypass grafting have not been comprehensively reviewed.

    Pneumothorax is a frequent and potentially fatal complication of mechanical ventilation in patients with acute respiratory distress syndrome (ARDS). Prompt recognition and treatment of pneumothoraces is necessary to minimize morbidity and mortality. The radiologic and clinical signs of pneumothoraces in ARDS patients may have unusual and subtle features. Furthermore, small pneumothoraces in these patients can cause severe hemodynamic or pulmonary compromise. Sparse clinical literature exists on when or how to treat pneumothoraces once they develop in patients with ARDS. In this article, the authors review the pathogenesis, radiologic signs, clinical significance, and treatment of pneumothoraces in ARDS patients. Treatment options include traditional tube thoracostomy, open thoracotomy, and image-guided percutaneous catheters.

    The study represents the retrospective analysis of major intestinal resections (the length of the left in olace bowel less then 200 sm) and non-major resections in 52 patients operated on the acute mesenterial thrombosis. Major bowel resection was performed in 30 patients (57.7%). 66.7% of those patients (20 of 30) died soon after the operation. Whereas lethality rate among patients with non-major resections was 54.5% (12 of 22). All 10 survived patients demonstrated the short-bowel syndrome during the follow-up period (the median follow-up time was 25 months).

    OBJECTIVE Despite increased information on the importance of an inappropriate inflammatory response in the acute Charcot process, there has been no previous attempt to define the specific pathways that mediate its pathogenesis. Here, the role played by monocytes was analyzed. RESEARCH DESIGN AND METHODS The immune phenotype of peripheral monocytes was studied by fluorescence-activated cell sorter analysis comparing patients with acute Charcot (n = 10) in both the active and recovered phase, diabetic patients with neuropathy (with or without osteomyelitis), and normal control subjects. RESULTS When compared with diabetic control subjects and healthy subjects, monocytes from acute Charcot patients showed a proinflammatory immune phenotype characterized by increased production of proinflammatory cytokines, reduced secretion of anti-inflammatory cytokines, increased expression of surface costimulatory molecules, and increased resistance to serum withdrawal-induced apoptosis. In addition, the pattern of circulating cytokines confirmed activation of proinflammatory cytokines. No modulation of the monocyte phenotype was documented in diabetic control subjects and healthy subjects, thus indicating that the proinflammatory alterations of monocytes are specific and causative of acute Charcot. CONCLUSIONS Together, these data provide evidence for the role of proinflammatory changes in the immune phenotype of monocytes in the pathogenesis of acute Charcot. These alterations may explain the abnormally intense and prolonged inflammatory response that characterizes this disorder and may represent a potential therapeutic target for specific pharmacological interventions.

    Objective. To assess whether acute stroke patients in rural hospitals receive less occupational therapy and physiotherapy than those in metropolitan hospitals. Design. Retrospective case-control study of health data in patients ≤10 days after stroke. Setting. Occupational therapy and physiotherapy services in four rural hospitals and one metropolitan hospital. Participants. Acute stroke patients admitted in one health district. Main Outcome Measures. Frequency and duration of face-to-face and indirect therapy sessions. Results. Rural hospitals admitted 363 patients and metropolitan hospital admitted 378 patients. Mean age was 73 years. Those in rural hospitals received more face-to-face (p > 0.0014) and indirect (p = 0.001) occupational therapy when compared to those in the metropolitan hospital. Face-to-face sessions lasted longer (p = 0.001). Patients admitted to the metropolitan hospital received more face-to-face (p > 0.000) and indirect (p > 0.000) physiotherapy when compared to those admitted to rural hospitals. Face-to-face sessions were shorter (p > 0.000). Almost all were seen within 24 hours of referral. Conclusions. Acute stroke patients in Australian rural hospital may receive more occupational therapy and less physiotherapy than those in metropolitan hospitals. The dose of therapy was lower than recommended, and the referral process may unnecessarily delay the time from admission to a patient's first therapy session. PMID:27752389

    Background. Individuals infected with chikungunya virus (CHIKV) normally exhibit a variety of clinical manifestations during the acute phase of infection. However, studies in different patient cohorts have revealed that disease manifestations vary in frequency. Methods. Disease profiles between patients with acute CHIKV-infection and febrile patients without CHIKV were compared and examined to determine whether any clinical presentations were associated with the clinical outcome of CHIKV infection. Circulatory immune mediators profiles were then characterized and compared with data from 14 independent patient cohort studies. The particular immune mediator signature that defines acute CHIKV infection was determined. Results. Our findings revealed a specific pattern of clinical presentations of joint-specific arthralgia from this CHIKV cohort. More importantly, we identified an immune mediator signature dominated by proinflammatory cytokines, which include interferon α and γ and interleukin 2, 2R, 6, 7, 12, 15, 17, and 18, across different patient cohorts of CHIKV load associated with arthralgia. Conclusions. To our knowledge, this is the first study that associated levels of CHIKV load with arthralgia as an indicator of acute CHIKV infection. Importantly, our findings also revealed specific immune mediator signatures that can be used to better define CHIKV infection. PMID:25635123

    BACKGROUND The objective of this study was to evaluate the association of some factors such as serum levels of homocysteine, folate and B12 vitamin with stroke in acute ischemic stroke patients. METHODS In this case control study, serum levels of homocysteine, folate and B12 vitamin in 93 patients with acute ischemic stroke admitted to Imam Khomeini Hospital between September 2008 and January 2010, and 93 healthy controls were measured. Cerebrovascular risk factors including age, sex, hypertension, hyperlipidemia, smoking, diabetes mellitus, alcohol consumption, coronary artery disease and obesity were recorded. The results were compared between the case and control groups. RESULTS The mean ± standard deviation (SD) of fasting total homocysteine (tHcy) level in acute ischemic stroke patients was 20.58 ± 19.6 µmol/l, which was significantly higher than that of control group being 14.11 ± 9.5 µmol/l (P = 0.002). 39 (41.9%) stroke cases and 25 (26.8%) controls had hyperhomocysteinemia. There were no significant relationships between tHcy, folate and B12 vitamin levels with the above mentioned cerebrovascular risk factors except for smoking (p> 0.05). No significant difference in B12 vitamin and folate levels between patients and healthy controls were detected (P> 0.05). CONCLUSION Hyperhomocysteinemia is common in Iranian patients with acute ischemic stroke and might play a role as an independent risk factor in stroke. PMID:22577454

    Objective No prior study appears to have focused on predictors of suicide in the general patient population admitted to psychiatric acute wards. We used a case-control design to investigate the association between suicide risk factors assessed systematically at admission to a locked-door psychiatric acute ward in Norway and subsequent death by suicide. Method From 2008 to 2013, patients were routinely assessed for suicide risk upon admission to the acute ward with a 17-item check list based on recommendations from the Norwegian Directorate of Health and Social Affairs. Among 1976 patients admitted to the ward, 40 patients, 22 men and 18 women, completed suicide within December 2014. Results Compared to a matched control group (n = 120), after correction for multiple tests, suicide completers scored significantly higher on two items on the check list: presence of suicidal thoughts and wishing to be dead. An additional four items were significant in non-corrected tests: previous suicide attempts, continuity of suicidal thoughts, having a suicide plan, and feelings of hopelessness, indifference, and/or aggression. A brief scale based on these six items was the only variable associated with suicide in multivariate regression analysis, but its predictive value was poor. Conclusion Suicide specific ideations may be the most central risk markers for suicide in the general patient population admitted to psychiatric acute wards. However, a low predictive value may question the utility of assessing suicide risk. PMID:28301590

    Acute aortic dissection is a rare, life-threatening condition requiring early recognition and proper treatment. Although chest pain remains the most frequent initial symptom, clinical manifestation of aortic dissection varies. Rarely aortic dissection starts with neurological symptoms such as ischemic stroke, which is usually right-sided. A danger of performing thrombolytic therapy in these patients exists if aortic dissection is overlooked. Herein, we present a case of a patient with acute aortic dissection without typical chest pain whose initial manifestation was bilateral stroke. The uncommon presentation which masked the underlying condition delayed implementation of appropriate management. Moreover, the late admission to hospital prevented the patient from administration of recombined tissue plasminogen activator that would certainly decrease chances of survival. Presented case highlights the need for thorough physical examination at admission to hospital in all patients with acute stroke and points out the necessity of proper clinical work-up including adequate aorta imaging modalities of patients with acute stroke and suggestive findings of aortic dissection.

    Invasive aspergillosis (IA) is a serious hazard to high-risk haematological patients. There are increasing reports of azole-resistant Aspergillus spp. This study assessed the epidemiology of IA and azole-resistant Aspergillus spp. in patients with acute leukaemia in Germany. A prospective multicentre cohort study was performed in German haematology/oncology centres. The incidence of probable and proven aspergillosis according to the revised EORTC/MSG criteria was assessed for all patients with acute leukaemia [acute myeloid leukaemia (AML) and acute lymphoblastic leukaemia (ALL)]. Cases were documented into a web-based case report form, and centres provided data on standards regarding prophylactic and diagnostic measures. Clinical isolates were screened centrally for azole resistance and, if applicable, underlying resistance mechanisms were analysed. Between September 2011 and December 2013, 179 cases of IA [6 proven (3.4%) and 173 probable (96.6%)] were diagnosed in 3067 patients with acute leukaemia. The incidence of IA was 6.4% among 2440 AML patients and 3.8% among 627 ALL patients. Mortality at Day 84 was 33.8% (49/145) and attributable mortality was 26.9% (39/145). At Day 84, 53 patients (29.6%) showed a complete response, 25 (14.0%) a partial response and 17 (9.5%) a deterioration or failure. A total of 77 clinical Aspergillus fumigatus isolates were collected during the study period. Two episodes of azole-resistant IA (1.1%) were caused by a TR/L98H mutation in the cyp51A gene. With only two cases of IA due to azole-resistant A. fumigatus, a change of antifungal treatment practices in Germany does not appear warranted currently.

    Backgrounds/Aims Frequently encountered in practice, the first-line treatment for acute cholecystitis is early or urgent cholecystectomy, with laparoscopic cholecystectomy (LC) being the preferred method. Percutaneous transhepatic gallbladder drainage (PTGBD) is considered as a safe alternative therapeutic option for resolving acute cholecystitis in surgically high-risk patients. We evaluated the surgical outcomes of acute cholecystitis, focusing on the differences between emergent LC without PTGBD, and scheduled LC following PTGBD. Methods Between March 2010 and December 2014, 294 patients with acute cholecystitis who had undergone LC, were retrospectively studied. Group I included 166 patients who underwent emergency LC without PTGBD. Group II included 128 patients who underwent scheduled LC after PTGBD. Clinical outcomes were analyzed according to each group. Results On admission, Group II had a higher mean level of c-reactive protein than Group I. According to the classification of the American Society of Anesthesiologists (ASA), group II had a greater number of high-risk patients than group I. There was no significant difference on perioperative outcomes between the two groups, including open conversion rate and complications. Analysis as per the ASA classes revealed no statistically remarkable finding between the groups. Conclusions There are no significant differences in the surgical outcomes of emergency LC group without PTGBD, and scheduled LC group following PTGBD. Comparison between two groups according to ASA classification reflecting the comorbidity and severity of condition of the patients also revealed no significant differences. However, scheduled LC following PTGBD is important for patients having acute cholecystitis with concurrent comorbidity. PMID:28317042

    The aim of the present study was to evaluate the prevalence of HEV, TTV and GBV-C/GBV-C/HGV in patients with acute viral hepatitis A, B and non-A-C. We evaluated sera of 94 patients from a sentinel program who had acute hepatitis A (N = 40), B (N = 42) and non-A-C (N = 12); 71 blood donors served as controls. IgM and anti-HEV IgG antibodies were detected by enzyme immunoassay using commercial kits. TTV and GBV-C/HGV were detected by nested PCR; genotyping was done by sequencing and phylogenetic analysis. Anti-HEV IgG was present in 38, 10 and 17% of patients with hepatitis A, B and non-A-C. Four patients with hepatitis A and 1 with non-A-C hepatitis also had anti-HEV IgM detected in serum. TTV was detected in 21% of patients with acute hepatitis and in 31% of donors. GBV-C/HGV was detected in 9% of patients with hepatitis, and in 10% of donors. We found TTV isolates of genotypes 1, 2, 3, and 4 and GBV-C/HGV isolates of genotypes 1 and 2. Mean aminotransferase levels were lower in patients who were TTV or GBV-C/HGV positive. In conclusion, the detection of anti-HEV IgM in some acute hepatitis A cases suggests co-infection with HEV and hepatitis E could be the etiology of a few cases of sporadic non-A-C hepatitis in Salvador, Brazil. TTV genotype 1, 2, 3 and 4 isolates and GBV-C/HGV genotype 1 and 2 strains are frequent in the studied population. TTV and GBV-C/HGV infection does not appear to have a role in the etiology of acute hepatitis.

    Background Natural health products (NHP) use may have implications with respect to adverse effects, drug interactions and adherence yet the prevalence of NHP use by patients with acute cardiovascular disease and the best method to ascertain this information is unknown. Objective To identify the best method to ascertain information on NHP, and the prevalence of use in a population with acute cardiovascular disease. Methods Structured interviews were conducted with a convenience sample of consecutive patients admitted with acute cardiovascular disease to the University of Alberta Hospital during January 2009. NHP use was explored using structured and open-ended questions based on Health Canada's definition of NHP. The medical record was reviewed, and documentation of NHP use by physicians, nurses, and pharmacists, compared against the gold-standard structured interview. Results 88 patients were interviewed (mean age 62 years, standard deviation [SD 14]; 80% male; 41% admitted for acute coronary syndromes). Common co-morbidities included hypertension (59%), diabetes (26%) and renal impairment (19%). NHP use was common (78% of patients) and 75% of NHP users reported daily use. The category of NHP most commonly used was vitamins and minerals (73%) followed by herbal products (20%), traditional medicines including Chinese medicines (9%), homeopathic preparations (1%) and other products including amino acids, essential fatty acids and probiotics (35%). In a multivariable model, only older age was associated with increased NHP use (OR 1.5 per age decile [95%CI 1.03 to 2.2]). When compared to the interview, the highest rate of NHP documentation was the pharmacist history (41%). NHP were documented in 22% of patients by the physician and 19% by the nurse. Conclusions NHP use is common in patients admitted with acute cardiovascular disease. However, health professionals do not commonly identify NHP as part of the medication profile despite its potential importance. Structured

    There is ample evidence that Staphylococcus aureus capsular polysaccharide (CP) promotes virulence. Loss of capsule expression, however, may lead to S. aureus persistence in a chronically infected host. This study was conducted to determine the relative prevalence of nonencapsulated S. aureus in patients with chronic and acute osteomyelitis. Only 76/118 (64%) S. aureus isolates from patients with osteomyelitis expressed CP, whereas all 50 isolates from blood cultures of patients with infections other than osteoarticular infections expressed CP (P = 0.0001). A significantly higher prevalence of nonencapsulated S. aureus was found in patients with chronic osteomyelitis (53%) than in those with acute osteomyelitis (21%) (P = 0.0046). S. aureus isolates obtained from multiple specimens from five of six patients with chronic osteomyelitis exhibited phenotypic (expression of CP, α-hemolysin, β-hemolysin, slime, and the small-colony variant phenotype) and/or genotypic (pulsed-field gel electrophoresis and spa typing) differences. Nonencapsulated S. aureus was recovered from at least one specimen from each chronic osteomyelitis patient. Fourteen isolates obtained from two patients with acute osteomyelitis were indistinguishable from each other within each group, and all produced CP5. In conclusion, we demonstrated that nonencapsulated S. aureus is more frequently isolated from patients with chronic osteomyelitis than from those with acute osteomyelitis, suggesting that loss of CP expression may be advantageous to S. aureus during chronic infection. Our findings on multiple S. aureus isolates from individual patients allow us to suggest that selection of nonencapsulated S. aureus is likely to have occurred in the patient during long-term bone infection.

    Purpose: We have previously shown that intensity-modulated radiotherapy (IMRT) can reduce dose to small bowel, bladder, and bone marrow compared with three-field conventional radiotherapy (CRT) technique in the treatment of rectal cancer. The purpose of this study was to review our experience using IMRT to treat rectal cancer and report patient clinical outcomes. Methods and Materials: A retrospective review was conducted of patients with rectal cancer who were treated at Mayo Clinic Arizona with pelvic radiotherapy (RT). Data regarding patient and tumor characteristics, treatment, acute toxicity according to the Common Terminology Criteria for Adverse Events v 3.0, tumor response, and perioperative morbidity were collected. Results: From 2004 to August 2009, 92 consecutive patients were treated. Sixty-one (66%) patients were treated with CRT, and 31 (34%) patients were treated with IMRT. All but 2 patients received concurrent chemotherapy. There was no significant difference in median dose (50.4 Gy, CRT; 50 Gy, IMRT), preoperative vs. postoperative treatment, type of concurrent chemotherapy, or history of previous pelvic RT between the CRT and IMRT patient groups. Patients who received IMRT had significantly less gastrointestinal (GI) toxicity. Sixty-two percent of patients undergoing CRT experienced {>=}Grade 2 acute GI side effects, compared with 32% among IMRT patients (p = 0.006). The reduction in overall GI toxicity was attributable to fewer symptoms from the lower GI tract. Among CRT patients, {>=}Grade 2 diarrhea and enteritis was experienced among 48% and 30% of patients, respectively, compared with 23% (p = 0.02) and 10% (p = 0.015) among IMRT patients. There was no significant difference in hematologic or genitourinary acute toxicity between groups. In addition, pathologic complete response rates and postoperative morbidity between treatment groups did not differ significantly. Conclusions: In the management of rectal cancer, IMRT is associated with a

    Incidence of AKI in hospitalized patients with cancer is increasing, but there have been few studies on AKI in patients with cancer. We conducted a retrospective cohort study in a South Korean tertiary care hospital. A total of 2211 consecutive patients (without cancer 61.5%; with cancer 38.5%) were included over a 140-month period. Predictors of all-cause death were examined using the Kaplan-Meier method and the Cox proportional hazards model. The main contributing factors of AKI were sepsis (31.1%) and ischemia (52.7%). AKI was multifactorial in 78% of patients with cancer and in 71% of patients without cancer. Hospital mortality rates were higher in patients with cancer (42.8%) than in patients without cancer (22.5%) (p = 0.014). In multivariate analyses, diabetes mellitus (DM) and cancer diagnosis were associated with hospital mortality. Cancer diagnosis was independently associated with mortality [odds ratio = 3.010 (95% confidence interval, 2.340-3.873), p = 0.001]. Kaplan-Meier analysis revealed that subjects with DM and cancer (n = 146) had lower survival rates than subjects with DM and without cancer (n = 687) (log rank test, p = 0.001). The presence of DM and cancer was independently associated with mortality in AKI patients both with and without cancer. Studies are warranted to determine whether proactive measures may limit AKI and improve outcomes.

    Posaconazole is a commonly used medication for antifungal prophylaxis in patients with high-risk acute leukemia, such as acute myeloid leukemia. Despite clinical data that show that posaconazole is superior to other antifungal prophylaxis medications, posaconazole is known to have many side effects and drug-drug interactions. We present a patient who developed rhabdomyolysis after being started on posaconazole for prophylaxis in the setting of relapsed acute myeloid leukemia.

Despite clinical data that show that posaconazole is superior to other antifungal prophylaxis medications, posaconazole is known to have many side effects and drug-drug interactions. We present a patient who developed rhabdomyolysis after being started on posaconazole for prophylaxis in the setting of relapsed acute myeloid leukemia. PMID:28203579

    After inpatient hospitalization, many elderly patients with congestive heart failure (CHF) are discharged home and receive post-acute home care from informal (family) caregivers and formal service providers. Hospital readmission rates are high among elderly patients with CHF, and it is thought that use of informal and formal services may reduce hospital readmission during the post-acute period. Using proportional Cox regression analysis, the authors examined the independent and joint effects of post-acute informal and formal services on hospital readmission. No evidence of service impact was found. Rather, hospital readmission was associated with a longer length of CHF history and noncompliance with medication regimes. Research, policy, and practice implications are discussed.

    We present a case of severe acute pancreatitis induced by hypertriglyceridemia secondary to lipoprotein lipase (LPL) deficiency in a pregnant patient with gestational diabetes, initially maneged with diet but it was later necessary to carry out artificial nutricional support measures: total parenteral nutrition. LPL deficiency might cause severe hypertriglyceridemia, repetition acute pancreatitis which is an unwieldy and severe situation during pregnancy. Acute familial hypertriglyceridemia pancreatitis accounts for 5% of cases, including LPL deficiency. The goal of treatment is to reach triglycerides levels below 500 mg/dl, being very low fat diet the treatment of choice, drugs or plasmapheresis techniques can also be associated. TPN enriched in ω3 fatty acids and glutamine was safe and effective in our patient with significant decrease in triglyceride levels.

    Aims To examine the extent of delay from initial hospital presentation to fibrinolytic therapy or primary percutaneous coronary intervention (PCI), characteristics associated with prolonged delay, and changes in delay patterns over time in patients with ST-segment elevation myocardial infarction (STEMI). Methods and results We analysed data from 5170 patients with STEMI enrolled in the Global Registry of Acute Coronary Events from 2003 to 2007. The median elapsed time from first hospital presentation to initiation of fibrinolysis was 30 min (interquartile range 18–60) and to primary PCI was 86 min (interquartile range 53–135). Over the years under study, there were no significant changes in delay times to treatment with either strategy. Geographic region was the strongest predictor of delay to initiation of fibrinolysis >30 min. Patient's transfer status and geographic location were strongly associated with delay to primary PCI. Patients treated in Europe were least likely to experience delay to fibrinolysis or primary PCI. Conclusion These data suggest no improvements in delay times from hospital presentation to initiation of fibrinolysis or primary PCI during our study period. Geographic location and patient transfer were the strongest predictors of prolonged delay time, suggesting that improvements in modifiable healthcare system factors can shorten delay to reperfusion therapy even further.

    Introduction In patients who present with acute cerebro-vascular disease, autonomic function testing is usually not given its due importance. This is because of the complex nature of the autonomic function tests and the relative technical difficulty faced in administering the tests to the patients. A simple and non-invasive method to assess the autonomic dysfunction is measurement of resting Heart Rate Variability (HRV). Aim To study the pattern of autonomic dysfunction among patients admitted with acute stroke and to study the relationship between autonomic dysfunction and the morbidity and mortality associated with acute stroke. Materials and Methods The study was carried out on 97 patients who were admitted with diagnosis of acute stroke. Patients with conduction abnormalities on ECG were excluded from the study. Resting ECG tracings were obtained for a period of 5 minutes. The frequency domain analysis of HRV was performed by a Fast Fourier transform of the RR intervals. The High Frequency (HF) was representative of the parasympathetic activity while low frequency is representative of baroreceptor mediated parasympathetic and sympathetic activity and Low Frequency (LF)/HF ratio was a measure of the sympathovagal balance. Statistical analysis was carried out with student’s t-test and chi-square test and p-value ≥ 0.05 was taken to be statistically significant. Results The mean age of the patients was 60.84±14.12 years. A total of 41 patients were females and 77 patients had ischemic stroke. Out of the total 97, 60 patients had evidence suggestive of increased sympathetic activity with a mean LF/HF ratio of 2.03±0.88. These patients had significantly higher mean systolic BP, diastolic BP and National Institute of Health Stroke Scale (NIHSS) values when compared to patients with reduced LF/HF ratio (166.33±24.81 vs 148.54±19.42, p=0.0003, 100.33±18.73 vs 88.76±12.66, p=0.0013, 15.77±8.22 vs 11.49±6.63, p=0.0088 respectively).

    The kinetics of autologous leukemic cells labeled with In-111 oxine were studied in 5 patients with acute myeloblastic leukemia (AML) and one patient with acute premyelocytic leukemia (APL), and kinetics of OKM1 monoclonal antibody-treated leukemic cells were studied in one patient with acute monoblastic leukemia (AMoL). Recoveries of 33.7 +- 23.3%(range, 22.0 to 48.1%) were achieved at 10min after injection of In-111 oxine labeled leukemic cells in AML and APL patients. However, in a patient with AMoL recovery of 12.3% was only achieved at 10min after injection of OKM1-treated leukemic cells. Clearance of the activity from blood was rapid up to one in all patients. The clearance curve of the activity in 5 AML patients showed a hump or a plateau from one to 5hr after injection of labeled leukemic cells. In APL patient and AMoL patient, however, this hump or plateau was not noted. In AML and APL patients the activity over the spleen was higher than that of over the liver at from 30min to 3hr after and showed a plateau or gradual rising thereafter. In a patient with AMoL, the hepatic activity was higher than the splenic activity at 30min after, but thereafter the latter became higher than the former. Liver activity curves showed transient fall at 3hr after and then gradual uprising in all patients. In a patient with APL, high activity was noted over the kidneys. This rose to a maximum after 3hr and then decreased rapidly. Since In-111 oxine stays firmly attached to the cells in spite of the possibility of radiation damage in a long-term survey, it seems an ideal label for studying leukemic cell kinetics.

    Because of the firm refusal of transfusion of blood and blood components by Jehovah's Witnesses, the management of Jehovah's Witness patients with severe bleeding is often complicated by medical, ethical, and legal concerns. Because of a rapidly growing and worldwide membership, physicians working in hospitals should be prepared to manage these patients. Appropriate management of a Jehovah's Witness patient with severe bleeding entails understanding of the legal and ethical issues involved, and meticulous medical management, including treatment of hypovolemic shock, local hemostatic interventions, and administration of prohemostatic agents, when appropriate. In addition, high-dose recombinant erythropoietin in combination with supplemental iron may enhance the speed of hemoglobin synthesis.

    The patient was a 23-year-old man, currently serving in a military airborne operations unit. During a jump training exercise, the patient's right lower extremity became entangled in his parachute equipment upon exiting the aircraft, which caused hyperextension and valgus forces upon his right knee. Due to concern for a fracture, the patient was transported to an emergency department, where conventional radiographs were completed and interpreted by a radiologist as negative for a fracture. Following further physical examination by a physical therapist, magnetic resonance imaging of the right knee was ordered, revealing ruptures of the anterior cruciate ligament and medial collateral ligament.

    Extracellular vesicles (EVs) are released from various cell types and play an important role in intercellular interactions. In our study, we investigated abundance of individual EVs in patients with acute forms of ischemic heart disease. Previously, we developed an approach for individual analysis of EVs conjugated with magnetic nanoparticles (MNPs), which was applied in the current study for analyzing phenotypic composition of EVs (by staining for markers CD31, CD41a, and CD63). EVs were isolated using fluorescently labeled MNPs containing anti-CD31, CD41a, or CD63 antibodies and analyzed by combining fluorescently labeled anti-CD41a and CD63, CD31 and CD63, or CD41a and CD31 antibodies, respectively. EVs were analyzed in 30 individuals: 17 healthy volunteers and 13 patients with acute coronary syndrome (ACS). Six and seven patients with ACS were with acute myocardial infarction and unstable angina, respectively. It was found that patients with ACS and healthy volunteers contained a dominant subset of EVs expressing surface CD41a antigen, suggesting that they originated from platelets. In addition, the total number of EVs isolated using either of the surface markers examined in our study was higher in patients with ACS compared to healthy volunteers. The subgroup of patients with acute myocardial infarction was found to contain significantly higher number of blood EVs compared to the control group. Moreover, increased number of EVs in patients with ACS is mainly due to the increased number of EVs in the subset of EVs bearing CD41a. By analyzing individual EVs, we found that plasma of patients with ACS, particularly upon developing of myocardial infarction, contained dominant platelet-derived EVs fraction, which may reflect activation of platelets in such patients.

    Background: Gender differences among patients with the acute coronary syndrome is still being debated, no research has been done on gender inequality among coronary syndrome patients in Sudan. Objectives: To study gender differences in presentation, management, and outcomes of acute coronary syndrome in Sudan. Subjects and Methods: This cross-sectional descriptive longitudinal study was conducted in Omdurman Teaching Hospital between July 2014 and August 2015. Patients were invited to sign a written informed consent form, were interviewed and examined by a physician, and then followed during their hospital stay. Information collected includes coronary risk factors, vital signs, echocardiography findings, arrhythmias, heart failure, cardiogenic shock, and death. The Ethical Committee of Omdurman Teaching Hospital approved the research. Results: A total of 197 consecutive acute coronary syndrome patients were included, 43.1% were females. A significant statistical difference was evident between males and females regarding the type of acute coronary syndrome, its presentation, and time of presentation to the hospital, smoking, and receipt of thrombolysis (P < 0.05). No differences were found with regard to age, hypertension, diabetes, family history of myocardial infarction, percutaneous coronary intervention, and in-hospital acute coronary complications (P > 0.05). Conclusion: Women were less likely to receive thrombolytic therapy, present with chest pain, and diagnosed with ST-segment elevation myocardial infarction. No gender differences were found in acute coronary syndrome risk factors apart from smoking, which was more common in males, and there were no differences between males and females as regards in-hospital complications.

    Introduction. Early laparoscopic cholecystectomy is usually associated with reduced hospital stay, sick leave, and health care expenditures. Early diagnosis and treatment of acute cholecystitis reduce both mortality and morbidity and the accurate diagnosis requires specific diagnostic criteria of clinical data and imaging studies. Objectives. To compare early versus delayed laparoscopic cholecystectomy regarding the operative outcome and patient satisfaction. Patients and Methods. Patients with acute cholecystitis were divided into two groups, early (A) and delayed (B) cholecystectomy. Diagnosis of acute cholecystitis was confirmed by clinical examination, laboratory data, and ultrasound study. The primary end point was operative and postoperative outcome and the secondary was patient's satisfaction. Results. The number of readmissions in delayed treatment group B was three times in 10% of patients, twice in 23.3%, and once in 66.7% while the number of readmissions was once only in patients in group A and the mean total hospital stays were higher in group B than in group A. The overall patient's satisfaction was 92.66 ± 6.8 in group A compared with 75.34 ± 12.85 in group B. Conclusion. Early laparoscopic cholecystectomy resulted in significant reduction in length of hospital stay and accepted rate of operative complications and conversion rates when compared with delayed techniques.

    ABSTRACT Introduction: Chronic obstructive pulmonary disease (COPD) is very prevalent worldwide, yet underdiagnosed. Aim: This study investigates feasibility of performing spirometry in patients in need of acute hospital admission as well as the prevalence of undiagnosed COPD in the same cohort. Methods: During a two-week period, all patients admitted to three large acute assessment units were evaluated. Patients ≥ 18 years, able to perform spirometry, with no surgery to the thorax or abdomen within the last weeks and no known COPD was included. Patients with FEV1/FEV6 ≤ 0.7 or FEV1 < 80% or FEV6 < 80% were offered follow-up visit after 6 weeks. Results: Of the 1145 admitted patients, 46% were eligible: 28% of those had an abnormal spirometry. The offered follow-up visit was attended by 51% and in this group 17% were diagnosed with lung disease. COPD was the most prevalent diagnosis (73%), and 2/3 was in GOLD group A. In total, 75% of the patients with airflow obstruction at the initial examination remained obstructive. Conclusion: Performing spirometry in patients in need of acute hospital admission is feasible, abnormal findings are common, and COPD is the most prevalent diagnosis. PMID:28326181

    This study aimed to explore the utility of arterial spin labeling perfusion-weighted imaging (ASL-PWI) in patients with suspected seizures in acute settings. A total of 164 patients who underwent ASL-PWI for suspected seizures in acute settings (with final diagnoses of seizure [n = 129], poststroke seizure [n = 18], and seizure mimickers [n = 17]), were included in this retrospective study. Perfusion abnormality was analyzed for: (1) pattern, (2) multifocality, and (3) atypical distribution against vascular territories. Perfusion abnormality was detected in 39% (50/129) of the seizure patients, most (94%, 47/50) being the hyperperfusion pattern. Of the patients with perfusion abnormality, multifocality or hemispheric involvement and atypical distribution against vascular territory were revealed in 46% (23/50) and 98% (49/50), respectively. In addition, seizures showed characteristic features including hyperperfusion (with or without non-territorial distribution) on ASL-PWI, thus differentiating them from poststroke seizures or seizure mimickers. In patients in whom seizure focus could be localized on both EEG and ASL-PWI, the concordance rate was 77%. The present study demonstrates that ASL-PWI can provide information regarding cerebral perfusion status in patients with seizures in acute settings and has the potential to be used as a non-invasive imaging tool to identify the cerebral perfusion in patients with seizures.

    The management of depression and other negative psychological states in cardiac patients has been a focus of multiple treatment trials, though such trials have not led to substantial improvements in cardiac outcomes. In contrast, there has been minimal focus on interventions to increase positive psychological states in cardiac patients, despite the fact that optimism and other positive states have been associated with superior cardiovascular outcomes. Our objective was to develop an 8-week, phone-based positive psychology intervention for patients hospitalized with acute cardiac disease (acute coronary syndrome or decompensated heart failure). Such an intervention would consist of positive psychology exercises adapted for this specific population, and it would need to be feasible for practitioners and patients in real-world settings. By adapting exercises that were previously validated in healthy individuals, we were able to generate a positive psychology telemedicine intervention for cardiac patients that focused on optimism, kindness, and gratitude. In addition, we successfully created a companion treatment manual for subjects to enhance the educational aspects of the intervention and facilitate completion of exercises. Finally, we successfully performed a small pilot trial of this intervention, and found that the positive psychology intervention appeared to be feasible and well-accepted in a cohort of patients with acute cardiac illness. Future studies should further develop this promising intervention and examine its impact on psychological and medical outcomes in this vulnerable population of cardiac patients.

    To establish the value of visual evoked potentials (VEPs) for monitoring disease evolution, we undertook a population-based study of 90 untreated patients 12 to 57 years of age (median, 32 years) at the onset of optic neuritis (ON) and after 2, 4, 12, and 52 weeks. Optic neuritis was monosymptomatic (AMON) in 58 patients and part of the clinically definite multiple sclerosis (CDMS) in 32 patients. The VEP was abnormal in eyes with acute ON in 69 (77%) of 90 patients at onset and in 80 (89%) of 90 patients at one or more of the follow-up sessions. In eyes with acute ON, normalization of an initially abnormal VEP was observed during 1-year follow-up in 13 (19%) of 69 patients. At onset of ON, VEP was abnormal in 35% of the clinically unaffected eyes. By parametric analysis of variance, the latencies (P = 0.0058), the amplitudes (P = 0.0298), and the combined VEP scores (P = 0.0345) in the eyes with acute ON were significantly associated with the time after onset. The latencies were influenced by the presence of CDMS (P = 0.0033), whereas the amplitudes were influenced by visual acuity (P = 0.0000). When visual acuity was included in a multifactor model, the time after onset was, however, not significantly associated with the amplitude (P = 0.8826). The mean latency of the VEPs in eyes with acute ON was significantly shorter in AMON than in ON as part of CDMS. This study provides evidence that VEP abnormality is often transitory, and that VEP often normalizes during follow-up. The diagnostic yield is increased by repeating VEP in the spontaneous course of acute ON. Visual evoked potential is a sensitive tool for revealing subclinical lesions.

    Dysphagia occurs in acute stroke patients at high rates, and many of them develop aspiration pneumonia. Team approaches with the cooperation of various professionals have the power to improve the quality of medical care, utilizing the specialized knowledge and skills of each professional. In our hospital, a multidisciplinary participatory swallowing team was organized. The aim of this study was to clarify the influence of a team approach on dysphagia by comparing the rates of pneumonia in acute stroke patients prior to and post team organization. All consecutive acute stroke patients who were admitted to our hospital between April 2009 and March 2014 were registered. We analyzed the difference in the rate of pneumonia onset between the periods before team organization (prior period) and after team organization (post period). Univariate and multivariate analyses were performed using a Cox proportional hazards model to determine the predictors of pneumonia. We recruited 132 acute stroke patients from the prior period and 173 patients from the post period. Pneumonia onset was less frequent in the post period compared with the prior period (6.9% vs. 15.9%, respectively; p = 0.01). Based on a multivariate analysis using a Cox proportional hazards model, it was determined that a swallowing team approach was related to pneumonia onset independent from the National Institutes of Health Stroke Scale score on admission (adjusted hazard ratio 0.41, 95% confidence interval 0.19–0.84, p = 0.02). The multidisciplinary participatory swallowing team effectively decreased the pneumonia onset in acute stroke patients. PMID:27138162

    Objective Municipality acute wards (MAWs) have recently been launched in Norway as an alternative to hospitalizations, and are aimed at providing treatment for patients who otherwise would have been hospitalized. The objective of this study was to explore how patients normally admitted to hospitals perceived the quality and safety of treatment in MAWs. Design The study had a qualitative design. Thematic analysis was used to analyze the data. Setting The study was conducted in a county in south-eastern Norway and included five different MAWs. Patients Semi-structured interviews were conducted with 27 participants who had required acute health care and who had been discharged from the five MAWs. Results Three subthemes were identified that related to the overarching theme of hospital-like standards (“almost a hospital, but…”), namely (a) treatment and competence, (b) location and physical environment, and (c) adequate time for care. Participants reported the treatment to be comparable to hospital care, but they also experienced limitations. Participants spoke positively about MAW personnel and the advantages of having a single patient room, a calm environment, and proximity to home. Conclusions Participants felt safe when treated at MAWs, even though they realized that the diagnostic services were not similar to that in hospitals. Geographical proximity, treatment facilities and time for care positively distinguished MAWs from hospitals, while the lack of diagnostic resources was stressed as a limitation.

    Possibly, acute esophagitis and pancreatitis cause each other, and we focused on sphincteric failure as the common causative key able to induce either esophagitis and acute pancreatitis or both of them, and thereby investigate the presence of a common therapy nominator. This may be an anti-ulcer pentadecapeptide BPC 157 (tested for inflammatory bowel disease, wound treatment) affecting esophagitis, lower esophageal and pyloric sphincters failure and acute pancreatitis (10 μg/kg, 10 ng/kg intraperitoneally or in drinking water). The esophagitis-sphincter failure procedure (i.e., insertion of the tubes into the sphincters, lower esophageal and pyloric) and acute pancreatitis procedure (i.e., bile duct ligation) were combined in rats. Esophageal manometry was done in acute pancreatitis patients. In rats acute pancreatitis procedure produced also esophagitis and both sphincter failure, decreased pressure 24 h post-surgery. Furthermore, bile duct ligation alone immediately declines the pressure in both sphincters. Vice versa, the esophagitis-sphincter failure procedure alone produced acute pancreatitis. What's more, these lesions (esophagitis, sphincter failure, acute pancreatitis when combined) aggravate each other (tubes into sphincters and ligated bile duct). Counteraction occurred by BPC 157 therapies. In acute pancreatitis patients lower pressure at rest was in both esophageal sphincters in acute pancreatitis patients. We conclude that BPC 157 could cure esophagitis/sphincter/acute pancreatitis healing failure.

    Objective: Calreticulin (CALR) plays important roles in cell proliferation, apoptosis, and immune responses. CALR mutations were described recently in Janus kinase 2 gene (JAK2)-negative or MPL-negative primary myelofibrosis (PMF) and essential thrombocythemia (ET) patients. CALR trails JAK2 as the second most mutated gene in myeloproliferative neoplasms (MPNs). However, little is known about CALR mutation in Chinese patients with leukemia. In the present study, a cohort of 305 Chinese patients with hematopoietic neoplasms was screened for CALR mutations, with the aim of uncovering the frequency of CALR mutations in leukemia and MPNs. Materials and Methods: Polymerase chain reaction and direct sequencing were performed to analyze mutations of CALR in 305 patients with hematopoietic malignancies, including 135 acute myeloid leukemia patients, 57 acute lymphoblastic leukemia patients, and 113 MPN patients. Results: CALR mutations were found in 10.6% (12 of 113) of samples from patients with MPNs. CALR mutations were determined in 11.3% (6 of 53), 21.7% (5 of 23), and 9.1% (1/11) of patients with ET, PMF, and unclassifiable MPN, respectively. Conclusion: We showed that MPN patients carrying CALR mutations presented with higher platelet counts and lower hemoglobin levels compared to those with mutated JAK2. However, all of the leukemia patients had negative results for CALR mutations. PMID:26377485

    Purpose: To present the patient outcomes and risk of symptomatic acute radiation pneumonitis (ARP) in 18 pediatric patients treated with helical tomotherapy to their craniospinal axis for a variety of neoplasms. Methods and Materials: A total of 18 patients received craniospinal axis irradiation with helical tomotherapy. The median age was 12 years (range, 2.5-21). The follow-up range was 3-48 months (median, 16.5). Of the 18 patients, 15 received chemotherapy in the neoadjuvant, adjuvant, or concomitant setting. Chemotherapy was tailored to the particular histologic diagnosis; 10 of 18 patients underwent surgical removal of the gross primary tumor. The patients were followed and evaluated for ARP starting at 3-6 months after completion of craniospinal axis irradiation. ARP was graded using the Common Toxicity Criteria, version 3. Results: At the last follow-up visit, 14, 2, and 2 patients were alive without disease, alive with disease, and dead of disease, respectively. The cause-specific survival rate was 89% (16 of 18), disease-free survival rate was 78% (14 of 18), and overall survival rate was 89% (16 of 18). No patient had treatment failure at the cribriform plate. No patient developed symptoms of ARP. Conclusion: Craniospinal axis irradiation using helical tomotherapy yielded encouraging patient outcomes and acute toxicity profiles. Although large volumes of the lung received low radiation doses, no patient developed symptoms of ARP during the follow-up period.

    Purpose: This study was designed to determine the feasibility and efficacy of endovascular embolization with liquid embolic agent ethylene vinyl alcohol copolymer (Onyx) in patients with acute traumatic arterial bleeding. Methods: This is a retrospective review of 13 patients (9 men and 4 women; mean age 45 years) with severe trauma who underwent embolotherapy using Onyx from November 2003 to February 2009. Bleeding was located in the pelvis (5 patients), kidney (3 patients), mesenteric region (2 patients), retroperitoneal space (2 patients), neck (1 patient), and thigh (1 patient). In three cases (23.1%), Onyx was used in conjunction with coils. We evaluate the technical and clinical success, procedural and embolization time, occurrence of rebleeding, and embolotherapy-related complications, such as necrosis or migration of Onyx into nontarget vessels. Results: In all patients, embolotherapy was technically and clinically successful on the first attempt. Control of bleeding could be reached with a mean time of 19 (range, 4-63) min after correct placement of the microcatheter in the feeding artery. No recurrent bleeding was detected. No unintended necrosis or migration of Onyx into a nontarget region was observed. During the follow-up period, three patients (23.1%) died due to severe intracranial hemorrhage, cardiac arrest, and sepsis. Conclusions: Transcatheter embolization with new liquid embolic agent Onyx is technically feasible and effective in trauma patients with acute arterial hemorrhage.

    Background In the last two decades, chikungunya virus (CHIKV) has rapidly expanded to several geographical areas, causing frequent outbreaks in sub-Saharan Africa, South East Asia, South America, and Europe. Therefore, the disease remains heavily neglected in Mozambique, and no recent study has been conducted. Methods Between January and September 2013, acute febrile patients with no other evident cause of fever and attending a health center in a suburban area of Maputo city, Mozambique, were consecutively invited to participate. Paired acute and convalescent serum samples were requested from each participant. Convalescent samples were initially screened for anti-CHIKV IgG using a commercial indirect immunofluorescence test, and if positive, the corresponding acute sample was screened using the same test. Results Four hundred patients were enrolled. The median age of study participants was 26 years (IQR: 21–33 years) and 57.5% (224/391) were female. Paired blood samples were obtained from 209 patients, of which 26.4% (55/208) were presented anti-CHIKV IgG antibodies in the convalescent sample. Seroconversion or a four-fold titer rise was confirmed in 9 (4.3%) patients. Conclusion The results of this study strongly suggest that CHIKV is circulating in southern Mozambique. We recommend that CHIKV should be considered in the differential diagnosis of acute febrile illness in Mozambique and that systematic surveillance for CHIKV should be implemented. PMID:26473605

    Pesticide formulation includes solvents (methanol and xylene) and antifreeze (ethylene glycol) whose metabolites are anions such as formic acid, hippuric acid, and oxalate. However, the effect of the anion gap on clinical outcome in acute pesticide intoxication requires clarification. In this prospective study, we compared the anion gap and other parameters between surviving versus deceased patients with acute pesticide intoxication. The following parameters were assessed in 1,058 patients with acute pesticide intoxication: blood chemistry (blood urea nitrogen, creatinine, glucose, lactic acid, liver enzymes, albumin, globulin, and urate), urinalysis (ketone bodies), arterial blood gas analysis, electrolytes (Na(+), K(+), Cl(-) HCO3 (-), Ca(++)), pesticide field of use, class, and ingestion amount, clinical outcome (death rate, length of hospital stay, length of intensive care unit stay, and seriousness of toxic symptoms), and the calculated anion gap. Among the 481 patients with a high anion gap, 52.2% had a blood pH in the physiologic range, 35.8% had metabolic acidosis, and 12.1% had acidemia. Age, anion gap, pesticide field of use, pesticide class, seriousness of symptoms (all P < 0.001), and time lag after ingestion (P = 0.048) were significant risk factors for death in univariate analyses. Among these, age, anion gap, and pesticide class were significant risk factors for death in a multiple logistic regression analysis (P < 0.001). In conclusions, high anion gap is a significant risk factor for death, regardless of the accompanying acid-base balance status in patients with acute pesticide intoxication.

    The hemodynamic effects of intravenously administered trinitroglycerin (TNT) and isosorbide dinitrate (ISDN) in stechiometric equivalent doses were studied in 30 patients with acute myocardial infarction. Both drugs were given over 30 min in every patient, and the stability of the condition of the patient was checked by administering the initial drug again. Measurements were made by right heart catheterization using a balloon tip thermodilution catheter and a catheter in the radial artery. TNT and ISDN have different hemodynamic effects. By multivariate analysis it could be shown that TNT is a venous dilator, lowering mainly pulmonary capillary pressure, while ISDN acts more as a mixed vasodilator, diminishing mainly peripheral vascular resistance and increasing cardiac output. These drugs have, therefore, a different spectrum of indications in patients with acute myocardial infarction.

    Abstract Eosinophilic with polyangiitis (EGPA, formerly known as Churg-Strauss syndrome) is a rare systemic disease characterized by a small-vessel necrotizing vasculitis. Cardiac manifestations are broad-ranging and are associated with a poor prognosis. Coronary vasospasm is uncommon. Here, we report a case of an acute coronary vasospasm in a patient with EGPA after corticosteroids withdrawal and nonsteroidal antiinflammatory drug (NSAID) introduction. This patient was initially misdiagnosed as bradykinin-mediated angioedema. A 30-year-old man presented with recurrence of abdominal pain and acute dyspnea. NSAID administration for pain during a flare was followed by coronary vasospasms leading to cardiac arrest. Corticosteroid treatment was recently interrupted by the patient. This case reports a rare cardiac complication of EGPA. NSAID might contribute to coronary vasospasm by eosinophilic degranulation in EGPA. Moreover, corticosteroid compliance must be emphasized among patients who display EGPA with high cardiac risk to prevent fatal issues. PMID:27893661

    The incidence of ischemic heart disease has been increased rapidly in Korea. However, the clinical effects of antecedent hypertension on acute myocardial infarction have not been identified. We assessed the relationship between antecedent hypertension and clinical outcomes in 7,784 patients with acute myocardial infarction in the Korea Acute Myocardial Infarction Registry during one-year follow-up. Diabetes mellitus, hyperlipidemia, cerebrovascular disease, heart failure, and peripheral artery disease were more prevalent in hypertensives (n=3,775) than nonhypertensives (n=4,009). During hospitalization, hypertensive patients suffered from acute renal failure, shock, and cerebrovascular event more frequently than in nonhypertensives. During follow-up of one-year, the incidence of major adverse cardiac events was higher in hypertensives. In multi-variate adjustment, old age, Killip class ≥III, left ventricular ejection fraction <45%, systolic blood pressure <90 mmHg on admission, post procedural TIMI flow grade ≤2, female sex, and history of hypertension were independent predictors for in-hospital mortality. However antecedent hypertension was not significantly associated with one-year mortality. Hypertension at the time of acute myocardial infarction is associated with an increased rate of in-hospital mortality. PMID:19794974

    Acute hepatitis C virus (HCV) is typically defined as new viremia and antibody seroconversion. Rates and immunologic correlates of hepatitis C clearance have therefore been based on clearance of viremia only in individuals who initially had an antibody response. We sought to characterize the immunological correlates of clearance in patients with acute hepatitis C and their sexual contacts. We prospectively determined CD4+ and CD8+ cytotoxic T-lymphocyte responses in index patients with acute HCV and their sexual contacts who developed acute infection, either with or without spontaneous clearance, as well as those contacts who never developed viremia. Responses were measured using proliferation and ELISpot assays for CD4+ and CD8+ responses. We demonstrate in this prospective study that cellular immune responses can develop in exposed but persistently aviremic and antibody-negative individuals as well as those individuals with spontaneous clearance of acute HCV. These findings lend further credence to the importance of cellular immune responses in recovery from HCV and suggest that low exposure to HCV may lead to development of HCV-specific immune responses without ongoing HCV replication. This finding has important implications for HCV vaccine and therapeutic development. PMID:15507612

    Natriuretic peptides have established prognostic value in heart failure (HF). The role of many other clinical and laboratory variables is still to be proved. The aim of this study was to assess prognostic determinants of death in acute HF in B-type natriuretic peptide (BNP)-matched patients. We conducted a case-control study to assess prognostic predictors of 6-month mortality in acute HF. From a prospectively recruited population of hospital-admitted patients with acute HF, we retrospectively selected a convenience sample of age-, gender-, and admission BNP-matched patients who survived (controls) or died (cases) in the follow-up period. Prognostic predictors of death were analyzed using a Cox regression analysis. A multivariate model was built. Variables in the model included atrial fibrillation, hypertension, admission heart rate, systolic blood pressure, the New York Heart Association class, hemoglobin, urea, albumin, systolic dysfunction, ischemic etiology, prognostic-modifying therapy, and BNP decrease during hospitalization. We analyzed 224 patients: 112 surviving and 112 not surviving a 6-month period. Median age was 80 years, 42.9% of the patients were men, and 63.9% had systolic dysfunction. Patients surviving the first 6 months had higher admission systolic blood pressure and heart rate, higher hemoglobin, lower urea, and more often had >30% decrease in BNP during hospitalization; they were more often discharged on HF prognostic modifying therapy. However, in multivariate analysis, the only independent mortality predictor was BNP decrease: patients in whom BNP decreased >30% had an HR of death of 0.57 (0.37 to 0.89). In conclusion, in BNP-matched patients with acute HF, the only independent mortality predictor is BNP decrease. Other literature suggested death predictors do not seem independent of natriuretic peptides.

    We herein report three ischemic stroke patients who underwent emergency carotid artery stenting after receiving intravenous tissue plasminogen activator (t-PA) treatment. All patients received antiplatelet medications immediately before stent placement for loading as well as dual antiplatelet therapy after stenting. Under high-dose and dual antiplatelet therapy, none of the three patients showed symptomatic intracranial hemorrhaging. However, one case showed reocclusion of the placed stent after acute thrombosis. As a result, new treatment strategies for the use of antiplatelet agents during emergency stent placement must be developed, particularly for patients who have received intravenous t-PA therapy.

    We describe four male patients suffering from quadriplegia caused by axonal Guillain-Barré syndrome. They were diagnosed with axonal Guillain-Barré syndrome based on their clinical course and electrophysiological findings. Three patients had severe pain, two had marked elevation of serum creatine kinase, one had finger contracture, and two required mechanical ventilation. Two of the patients recovered during the period from nadir to discharge in the Hughes functional grading scale and Barthel index. A physical therapist should understand the characteristics of severe axonal Guillain-Barré syndrome in an acute stage, and consider the psychological status of the patients.

    Posaconazole is a new oral triazole with broad-spectrum antifungal activity. Posaconazole has also shown a significant advantage of preventing invasive fungal infection compared to fluconazole or itraconazole in patients with prolonged neutropenia. Indeed, posaconazole has been commonly used for antifungal prophylaxis in patients undergoing remission induction chemotherapy for acute myelogenous leukemia or myelodysplastic syndrome. We experienced a case of fatal mucormycosis despite posaconazole prophylaxis. To our knowledge, this is the first reported case of fatal breakthrough mucormycosis in a patient receiving posaconazole prophylaxis during remission induction chemotherapy in Korea. This case demonstrated that breakthrough fungal infection can occurs in patients receiving posaconazole prophylaxis because of its limited activity against some mucorales.

    Abstract Background: The treatment of chronic hepatitis C virus infection has been revolutionized by the advent of direct-acting antiviral agents. However, evidence of its effects on patients with acute hepatitis C (AHC) virus infection is limited. Case summary: We report the case of a patient with decompensated cirrhosis induced by autoimmune liver disease, whose condition rapidly deteriorated following AHC virus infection. The patient received sofosbuvir and ribavirin combination treatment for 12 weeks. Serum hepatitis C virus RNA remained undetectable 36 weeks after discontinuing sofosbuvir and ribavirin. Conclusion: Our findings support the use of sofosbuvir and ribavirin as a treatment in AHC patients with decompensated cirrhosis. PMID:27930559

    Giardiasis is a common cause of diarrhea in undeveloped countries, but is very rare in developed countries. A patient with acute myelogenous leukemia and retinoblastoma presented with a high fever and severe watery diarrhea during induction chemotherapy. On microscopy, cysts were seen in her stool, suggesting Giardia intestinalis, which was confirmed on polymerase chain reaction (PCR). G. intestinalis was also detected in the patient's asymptomatic parents, who may have transmitted it to the patient. Giardiasis should be tested for in patients with severe and persistent diarrhea during chemotherapy, when other etiologies have been excluded. PCR used to amplify the DNA of G. intestinalis is rapid and sensitive.

    Low level of blood cholesterol is often found in patients with diseases which pathogenesis is mainly associated with inflamation. To detect blood cholesterol spectre, 383 patients with acute and chronic infections have been observed, level of blood cholesterol of 1259 patients with different pathology was retrospectively analyzed. It was found that an increase in frequency of low cholesterol and decrease in frequency of high cholesterol in patients with diseases not associated with infections do not depend on the age of patients. Extremely low level of cholesterol (Cholesterol < or = 100 mg/dl) is found in 12,8% of patients with inflamation of infectious origion, oftener in patients with community-acquired pneumonia and chronic virus hepatitis. Patients with intestinal infections have extremely low level of cholesterol; two-fold oftener than healthy persons have.

    Background and Purpose: The projected increase in persons with advanced heart failure and associated costs warrant the examination of exercise in patients receiving inotropic therapy. Literature supports the use of exercise and inotropic therapy in the treatment of patients with advanced heart failure. The purposes of this paper are to illustrate the use of exercise prescription and outcomes assessment with a 6-minute walk test in a patient with acute decompensated heart failure receiving tailored therapy with dobutamine and to discuss potential relationships resulting in observed improvements. Case Description: A 67-year old man was admitted to an acute care hospital with acute decompensated heart failure for tailored medical therapy including dobutamine. The patient received 14 days of tailored medical therapy, of which 12 days included exercise training by a physical therapist. Outcomes: Functional outcomes showed a clinically significant improvement in distance walked and improvement in the cardiorespiratory response. The improvement in estimated peak oxygen consumption was 7% greater than that predicted to be from tailored medical therapy. Discussion: Exercise was safely provided to a patient hospitalized with advanced heart failure on continuous inotropic therapy. The 6-minute walk test was effectively used to prescribe exercise and examine patient outcomes. PMID:21637393

    Dysphagia after stroke is associated with mortality and increased pulmonary complications. Swallowing therapies may decrease pulmonary complications and improve patients' quality of life after stroke. This study used clinical swallowing assessments and videofluoroscopy (VFS) to assess the functional recovery of acute stroke patients with dysphagia after different swallowing therapies. We enrolled 29 acute stroke patients with dysphagia and randomly divided them into 3 therapy groups: traditional swallowing (TS), oropharyngeal neuromuscular electrical stimulation (NMES), and combined NMES/TS. All patients were assessed using the clinical functional oral intake scale (FOIS), 8-point penetration-aspiration scale (PAS), and functional dysphagia scale (FDS) of VFS before and after treatment. There were no differences in the clinical parameters and swallowing results of the FOIS and VFS before swallowing treatment among the 3 groups (P > .05). TS therapy and combined therapy both had significant swallowing improvement after therapy according to the FOIS and 8-point PAS (P < .05). When comparing the results of the VFS among the 3 groups, we found significant improvements in patients eating cookies and thick liquid after combined NMES/TS therapy (P < .05). In acute stroke patients with dysphagia, combined NMES/TS therapy is the most effective swallowing therapy in taking solid diets and thick liquids.

    Purpose Prolonged recovery time of pulmonary function after an asthma exacerbation is a significant burden on asthmatics, and management of these patients needs to be improved. The aim of this study was to evaluate factors associated with a longer recovery time of pulmonary function among asthmatic patients hospitalized due to a severe asthma exacerbation. Methods We retrospectively reviewed the medical records of 89 patients who were admitted for the management of acute asthma exacerbations. The recovery time of pulmonary function was defined as the time from the date each patient initially received treatment for asthma exacerbations to the date the patient reached his or her previous best FEV1% value. We investigated the influence of various clinical and laboratory factors on the recovery time. Results The median recovery time of the patients was 1.7 weeks. Multiple linear regression analysis revealed that using regular inhaled corticosteroids (ICS) before an acute exacerbation of asthma and concurrent with viral infection at admission were associated with the prolonged recovery time of pulmonary function. Conclusions The prolonged recovery time of pulmonary function after a severe asthma exacerbation was not shown to be directly associated with poor adherence to ICS. Therefore the results indicate that an unknown subtype of asthma may be associated with the prolonged recovery of pulmonary function time after an acute exacerbation of asthma despite regular ICS use. Further prospective studies to investigate factors affecting the recovery time of pulmonary function after an asthma exacerbation are warranted. PMID:27582400

    Continuous flow left ventricular assist devices (LVADs) are used with good outcome. However, acute intravascular hemolysis due to thrombus in the pump remains a clinical challenge. We screened for LVAD-related intravascular hemolysis among 115 consecutive patients surviving HeartMateII implantation and investigated the role of medical therapy in resolving the hemolysis. Hemolytic events were identified in 7% of patients, 2-26 months after implant, manifested by peak lactate dehydrogenase (LDH) levels >6 times normal. With the institution of heparin and enhanced antiplatelet therapy, LDH levels receded rapidly reaching a stable trough level near baseline within 2 weeks with the resolution of clinical symptoms except in one patient who required additional therapy with tissue plasminogen activator (tPA). Complications included transient renal failure, one splenic infarct, and a cerebrovascular attack after tPA. The acute event of hemolysis resolved with medical therapy, and all were successfully discharged. However, recurrent hemolysis was common (6/8 patients over the next 1-7 months). At the end of follow-up, three patients were transplanted, one patient died refusing LVAD exchange for recurrent hemolysis, and 4 remained alive on LVAD support. Medical treatment with intensification of anticoagulation can be effective in resolving the acute hemolytic event. However, a definitive long-term strategy should be planned because the recurrence rate is high.

    The effects of coronary artery recanalization by intracoronary administration of streptokinase on left ventricular function during acute myocardial infarction have received increasing attention in recent years. Although myocardial dysfunction is often more pronounced in the right ventricle than in the left ventricle in patients with acute inferior wall myocardial infarction, the effect of coronary artery recanalization on right ventricular dysfunction has not been previously addressed. Accordingly, in this investigation, 54 patients who participated in a prospective, controlled, randomized trial of recanalization during acute myocardial infarction were studied. Among 30 patients with inferior wall infarction, 19 had right ventricular dysfunction on admission; 11 of these 19 had positive uptake of technetium-99m pyrophosphate in the right ventricle, indicative of right ventricular infarction. Patients with successful recanalization exhibited improved right ventricular ejection fraction from admission to day 10. However, control patients and patients who did not undergo recanalization also exhibited improvement. These data indicate that the right ventricular dysfunction commonly associated with inferior wall infarction is often transient, and improvement is the rule, irrespective of early recanalization of the infarct vessel.

    Background This study evaluated factors influencing early and late occurrence of AKI in severely burned patients and assessed the relationship between time of occurrence of AKI and mortality of AKI patients. Material/Methods Renal function was evaluated at 3 time points: at admission, at the critical point or middle point of hospitalization, and at the endpoint for which death or a discharge from the center was considered. AKI criteria were: decrease in GFR of less than 60 ml/min at admission, decrease in GFR of more than 75% compared to baseline, and decrease in the daily diuresis of less than 500 ml/24 h. Results At admission, 15.1% of the patients had eGFR <60 ml/min. AKI occurred in 38.5% of cases. The occurrence of AKI was associated with: elderly age (p<0.001), female sex (p=0.017), overweight and obesity (p=0.055); extent and depth of burns, respiratory failure, low protein concentration (for all p<0.001), low blood pressure (p=0.014), and high WBC (p=0.010). Early AKI was detected in 28% of patients. Mortality was 100% with the initial GFR ≥60, 100% with the initial GFR <60 and early deterioration of renal function, 80% with the initial GFR <60 and late worsening, and 60% with the initial GFR <60 and no worsening. Late AKI was observed in 10% of patients and mortality in this group was 79.2%. Mortality in the entire group with AKI was 88.0% versus 24.5%. Conclusions The frequent occurrence of AKI, especially early, worsens the prognosis for survival. Assessment of renal function should be included in the prognostic scales for burned patients.

  6. A major T cell antigen of Mycobacterium leprae is a 10-kD heat-shock cognate protein

    PubMed Central

    1992-01-01

    Several mycobacterial antigens, identified by monoclonal antibodies and patient sera, have been found to be homologous to stress or heat-shock proteins (hsp) defined in Escherichia coli and yeast. A major antigen recognized by most Mycobacterium leprae-reactive human T cell lines and cell wall-reactive T cell clones is a 10-kD protein that has now been cloned and sequenced. The predicted amino acid sequence of this protein is 44% homologous to the hsp 10 (GroES) of E. coli. The purified native and recombinant 10-kD protein was found to be a stronger stimulator of peripheral blood T cell proliferation than other native and recombinant M. leprae proteins tested. The degree of reactivity paralleled the response to intact M. leprae throughout the spectrum of leprosy. Limiting-dilution analysis of peripheral blood lymphocytes from a patient contact and a tuberculoid patient indicated that approximately one third of M. leprae-reactive T cell precursors responded to the 10- kD antigen. T cell lines derived from lepromin skin tests were strongly responsive to the 10-kD protein. T cell clones reactive to both the purified native and recombinant 10-kD antigens recognized M. leprae- specific epitopes as well as epitopes crossreactive with the cognate antigen of M. tuberculosis. Further, the purified hsp 10 elicited strong delayed-type hypersensitivity reactions in guinea pigs sensitized to M. leprae. The strong T cell responses against the M. leprae 10-kD protein suggest a role for this heat-shock cognate protein in the protective/resistant responses to infection. PMID:1730920

    Background Resistance to intravenous immunoglobulin (IVIG) occurs in 10–20% of patients with Kawasaki disease (KD). The risk of resistance is about two-fold higher in patients with elevated gamma glutamyl transferase (GGT) levels. We sought to understand the biological mechanisms underlying IVIG resistance in patients with elevated GGT levels. Method We explored the association between elevated GGT levels and IVIG-resistance with a cohort of 686 KD patients (Cohort I). Gene expression data from 130 children with acute KD (Cohort II) were analyzed using the R square statistic and false discovery analysis to identify genes that were differentially represented in patients with elevated GGT levels with regard to IVIG responsiveness. Two additional KD cohorts (Cohort III and IV) were used to test the hypothesis that sialylation and GGT may be involved in IVIG resistance through neutrophil apoptosis. Results Thirty-six genes were identified that significantly explained the variations of both GGT levels and IVIG responsiveness in KD patients. After Bonferroni correction, significant associations with IVIG resistance persisted for 12 out of 36 genes among patients with elevated GGT levels and none among patients with normal GGT levels. With the discovery of ST6GALNAC3, a sialyltransferase, as the most differentially expressed gene, we hypothesized that sialylation and GGT are involved in IVIG resistance through neutrophil apoptosis. We then confirmed that in Cohort III and IV there was significantly less reduction in neutrophil count in IVIG non-responders. Conclusions Gene expression analyses combining molecular and clinical datasets support the hypotheses that: (1) neutrophil apoptosis induced by IVIG may be a mechanism of action of IVIG in KD; (2) changes in sialylation and GGT level in KD patients may contribute synergistically to IVIG resistance through blocking IVIG-induced neutrophil apoptosis. These findings have implications for understanding the mechanism of

    The dynamics of cytopathic hypoxia markers in patients with acute pancreatitis (AP) biliary etiology (BE), depending on the presence of concomitant diabetes mellitus (DM), which is an independent factor of premorbid severity increase and increase in the degree of operational and anesthetic risk. Markers of cytopathic hypoxia use as methods for early diagnosis of acute liver failure (ALF) and monitoring the effectiveness of its correction promising. In terms of cytopathic hypoxia may be at the stage of laboratory diagnostics to distinguish between destructive and non-destructive forms APBE, and for markers of endothelial dysfunction--destructive forms on the area and depth of destruction of the pancreas.

    The authors present an unusual case of an acute swelling of the lower lip and septicemia in a 35-year-old, recent immigrant male arriving from India. The patient presented in our emergency department with a 48-hour history of a worsening, painful swelling of the lower lip. On presentation, he was pyrexial and the lip was found to be acutely inflamed with honey-colored crusting, pustular lesions, and induration . A diagnosis of impetigo leading to necrosis of the lip was established, a rare phenomenon potentially resulting in significant tissue destruction. Appropriate medical management achieved a good outcome and prevented disabling tissue loss of the orofacial region.

    We studied effect of time on the outcome of acute coronary syndrome and elevated ST segment at the prehospital stage. Logistic regression analysis revealed two time-dependent predictors: "symptom-needle" time and total call service time. In patients undergoing prehospital thrombolysis, these indices (88 and 85 min respectively) reliably predicted the probability of fatal outcome. Their values of 71 and 77 min respectively predicted the risk of unfavourable outcome. The total call service time may serve as an indicator of the quality of work of an ambulance crew at the prehospital stage of management of acute coronary syndrome with elevated ST segment.

    The recurrence rate for acute appendicitis treated nonoperatively varies between studies. Few studies have adequately evaluated the management of these patients when appendicitis recurs. We aimed to explore the recurrence rate and management of patients with acute appendicitis that were first treated nonoperatively.We identified patients in the Taiwan National Health Insurance Research Database who were hospitalized due to acute appendicitis for the first time between 2000 and 2010 and received nonsurgical treatment. The recurrence and its management were recorded. Data were analyzed to access the risk factors for recurrence and factors that influenced the management of recurrent appendicitis.Among the 239,821 patients hospitalized with acute appendicitis for the first time, 12,235 (5.1%) patients were managed nonoperatively. Of these, 864 (7.1%) had a recurrence during a median follow-up of 6.5 years. Appendectomy was performed by an open and laparoscopic approach in 483 (55.9%) and 258 (29.9%) patients, respectively. The remaining 123 (14.2%) patients were again treated nonsurgically. Recurrence was independently associated with young age, male sex, percutaneous abscess drainage, and medical center admission by multivariable analysis. In addition, age <18, a (CCI) <2, medical center admission, and a longer time to recurrence were correlated with using laparoscopy to treat recurrence. Neither type of appendicitis, percutaneous abscess drainage, nor length of first time hospital stay had an influence on the selection of surgical approach.In conclusion, a laparoscopic appendectomy can be performed in recurrent appendicitis cases, and its application may not be related to previous appendicitis severity.

    Gallium-67 (67Ga) accumulates in malignant tissues via the transferrin receptor without need for a monoclonal antibody and emits cytotoxic low-energy electrons. In this study we investigated the feasibility, pharmacokinetics, toxicity and preliminary efficiency of high-dose 67Ga injected intravenously (i.v.) in patients with acute leukaemia not responding to conventional therapy. Twelve doses of 36-105 mCi of Gallium67 citrate were administered as a push injection to eight patients with resistant leukaemia in a pilot study. All five patients with acute myeloid leukaemia (AML) and three patients with acute lymphoblastic leukaemia (ALL) had resistant disease or resistant relapse. No (sub)acute toxicity was observed. Independent of the administered dose, whole-blood radioactivity levels 10 min after administration measured only 1.25 +/- 1.39 microCi ml-1, indicating a large volume of distribution. Urine excretion in the first 24 h ranged from 18% to 51.5% (median 29.5%) of the administered dose. Cellular uptake of 67Ga was less than in previous in vitro studies. Whole-body radiation dose was estimated to be 0.25 +/- 0.03 cGy mCi-1. Red marrow dose was estimated to be between 0.18 +/- 0.02 and 0.97 +/- 0.12 cGy mCi-1. One definite response was observed in an ALL patient with disappearance of skin lesions, normalisation of the enlarged spleen and profound leucopenia. Three other patients showed transient reductions in white blood cell counts without disappearance of blasts from the peripheral blood. We conclude that high-dose i.v. 67Ga can be safely administered but that the uptake of 67Ga in blast cells must increase to make 67Ga therapeutically useful in patients with relapsed leukaemia.

    Background and Objectives There is an emerging evidence base for the use of music therapy in the treatment of severe mental illness. Whilst different models of music therapy have been developed in mental health care, none have specifically accounted for the features and context of acute in-patient settings. This review aimed to identify how music therapy is provided for acute adult psychiatric in-patients and what outcomes have been reported. Review Methods A systematic review using medical, psychological and music therapy databases. Papers describing music therapy with acute adult psychiatric in-patients were included. Analysis utilised narrative synthesis. Results 98 papers were identified, of which 35 reported research findings. Open group work and active music making for nonverbal expression alongside verbal reflection was emphasised. Aims were engagement, communication and interpersonal relationships focusing upon immediate areas of need rather than longer term insight. The short stay, patient diversity and institutional structure influenced delivery and resulted in a focus on single sessions, high session frequency, more therapist direction, flexible use of musical activities, predictable musical structures, and clear realistic goals. Outcome studies suggested effectiveness in addressing a range of symptoms, but were limited by methodological shortcomings and small sample sizes. Studies with significant positive effects all used active musical participation with a degree of structure and were delivered in four or more sessions. Conclusions No single clearly defined model exists for music therapy with adults in acute psychiatric in-patient settings, and described models are not conclusive. Greater frequency of therapy, active structured music making with verbal discussion, consistency of contact and boundaries, an emphasis on building a therapeutic relationship and building patient resources may be of particular importance.

    Diabetes, chronic obstructive pulmonary disease (COPD) and anemia are comorbidities with a high prevalence and impact in heart failure (HF). The presence of these comorbidities considerably worsens the prognosis of HF. Diabetic patients have a higher likelihood of developing symptoms of HF and both the treatment of diabetes and that of acute HF are altered by the coexistence of both entities. The glycemic targets in patients with acute HF are not well-defined, but could show a U-shaped relationship. Stress hyperglycemia in non-diabetic patients with HF could also have a deleterious effect on the medium-term prognosis. The inter-relationship between COPD and HF hampers diagnosis due to the overlap between the symptoms and signs of both entities and complementary investigations. The treatment of acute HF is also altered by the presence of COPD. Anemia is highly prevalent and is often the direct cause of decompensated HF, the most common cause being iron deficiency anemia. Iron replacement therapy, specifically intravenous forms, has helped to improve the prognosis of acute HF.

    Oxidative stress and inflammatory mediators, such as IL-6, play an important role in the pathophysiology of acute pancreatitis. The study was aimed to assess the degree of the pro/antioxidative imbalance and estimate which antioxidant plays a role in the maintenance of pro/antioxidative balance during acute pancreatitis. The study was investigated in the blood of 32 patients with acute pancreatitis and 37 healthy subjects. IL-6 concentration as early marker of inflammation was determinated. The intensity of oxidative stress was assessed by TBARS concentration. To investigate antioxidative status, the GPx and Cu/Zn SOD activities and the levels of GSH, MT, SH groups, and TRAP were measured. The concentrations of Cu and Zn as ions participating in the maintenance of antioxidant enzymes stability and playing a role in the course of disease were determinated. The activities of GGT, AAP, NAG, and β-GD as markers of tissue damage were also measured. An increase in IL-6 concentration, which correlated with Ranson criteria, and an increase in GPx activity, levels of MT, TBARS, or GGT, and NAG activities in patients group compared to healthy subjects were demonstrated. A decrease in GSH level in patients group compared to control group was noted. The studies suggest that GPx/GSH and MT play the role of the first line of defence against oxidative stress and pro/antioxidant imbalance in the course of acute pancreatitis. PMID:25298618

    We report three cases of patients with developmental-delay from neonatal herpetic encephalitis and/or meningitis who presented years later with acute retinal necrosis due to herpes simplex virus. The diagnosis was delayed in all cases due to the patients' inability to verbalize their ocular complaints and cooperate with eye examinations. This case series documents the clinical course, pathophysiologic mechanism, and treatment of acute retinal necrosis in this patient population. Clinicians should understand the importance of prudent consideration of acute retinal necrosis in patients with a history of neonatal herpetic encephalitis and/or meningitis presenting with a red eye.

Since Clostridium difficile is the most common cause of nosocomial infectious diarrhoea in non-haematologic patients, we were interested in its incidence in patients with acute myeloid leukaemia (AML). In this retrospective study, we analysed 134 patients with AML receiving a total of 301 chemotherapy courses. Diarrhoea occurred during 33% of all courses in 58 patients. C. difficile-associated diarrhoea (CDAD) occurred in 18% of all patients and 9% of all treatment courses. Almost one third of diarrhoea episodes were caused by C. difficile. CDAD was associated with older age (58 vs. 50 years), number of antibiotics administered (2 vs. 1), duration of antibiotic therapy (7 vs. 4 days), ceftazidime as the antibiotic of choice (75% vs. 54%) and duration of neutropenia (12 vs. 7 days) prior to onset of diarrhoea. An increased risk for CDAD was seen for prolonged neutropenia. CDAD responded well to oral metronidazole and/or vancomycin and no patient died of this complication. In conclusion, CDAD is common in patients with AML receiving chemotherapy. C. difficile enterotoxin testing of stool specimens should be included in all symptomatic patients.

    Acute myeloid leukemia (AML) is the most common acute leukemia in adults, and its incidence increases with age. Clinical outcomes in younger patients have improved over the years but, unfortunately, there is little evidence for an equivalent improvement in outcome for older patients. Approximately 50 % of older patients who are able to receive intensive chemotherapy will achieve a complete remission; however, they face a much higher relapse rate than younger patients, and survival rates for this group are low. Therefore, there is an urgent need to improve outcomes in older patients with AML. In this article, we discuss current treatment paradigms for older patients with AML including the challenges faced when determining which patients are eligible for intensive chemotherapy. We then highlight new treatments in development that may benefit this patient group. Cytotoxic agents, hypomethylating agents, molecularly targeted agents, and cell cycle kinase inhibitors are discussed, with a focus on novel agents that have achieved an advanced stage of development. Overall, the treatment of AML in older patients remains a challenge and, whenever possible, treatment should be offered in the context of clinical trials and should be planned with curative intent.

    Background Mycoplasma is a common cause of respiratory infections and may require differential diagnosis from Kawasaki disease (KD). In this study, we investigated the frequency and clinical manifestations of mycoplasma infection in patients with KD. Materials and Methods Medical records of 375 in-patients admitted for treatment during the acute stage of KD, were collected, and reviewed retrospectively. Of these patients, 152 (40.5%) were also tested for recent mycoplasma infection. Patients with positive results (anti-mycoplasma IgM Ab >1:640 or cold agglutinin >1:64) were designated as the case group (n = 37, 24.3%) whereas those with negative results were designated as the control group (n = 115, 75.7%). Clinical findings of the two groups were compared. Results Patients in the case group were older than those in the control group (mean age, 48.2 ± 32.1 months, vs. 31.7 ± 21.7 months; P = 0.001). There were significant differences between the case and control groups in the changes in the extremities (78.3% vs. 57.4%, respectively; P = 0.031), and in fever duration (6.5 ± 2.5 days vs. 5.4 ± 1.5 days; P = 0.047). Of the 37 patients with positive mycoplasma testing, 7 (18.9%) had persistent fever even after the symptoms and signs of systemic inflammation (acute phase of KD) had been resolved. These patients were positive for mycoplasma infection during further evaluation of persistent fever, and all of them responded to macrolide antibiotics. Conclusions We found that mycoplasma infection is somewhat related to KD. When fever persists after resolution of the acute stage of KD, mycoplasma infection may be considered as a possible cause of fever in preschool-aged children. PMID:28271651

    Care of burn-injured patients requires knowledge of the pathophysiologic changes affecting virtually all organs from the onset of injury until wounds are healed. Massive airway and/or lung edema can occur rapidly and unpredictably after burn and/or inhalation injury. Hemodynamics in the early phase of severe burn injury are characterized by a reduction in cardiac output, increased systemic and pulmonary vascular resistance. Approximately 2–5 days after major burn injury, a hyperdynamic and hypermetabolic state develops. Electrical burns result in morbidity much higher than expected based on burn size alone. Formulae for fluid resuscitation should serve only as guideline; fluids should be titrated to physiologic end points. Burn injury is associated basal and procedural pain requiring higher than normal opioid and sedative doses. Operating room concerns for the burn-injured patient include airway abnormalities, impaired lung function, vascular access, deceptively large and rapid blood loss, hypothermia and altered pharmacology.

    I describe four patients who successfully escaped from the hospital to their own home during the acute phase of ischemic stroke. This is a very rare phenomenon (seen in 0.35% of 1150 consecutive patients with first ischemic stroke within 24 h after onset), but the patients had rather uniform clinical characteristics. All were male, around 60 years old, had moderate to severe aphasia (Wernicke’s in 2 patients, Broca's in 1, and transcortical motor in 1), and cerebral infarction of the left middle cerebral artery territory. None had significant motor weakness, hemispatial neglect, or hemianopia at the time of escape. Overall functional outcome was good for all but one patient, but aphasia persisted in three. Although none of the four patients sustained serious injury during the escape, patients with such clinical characteristics must be managed cautiously to prevent serious consequences. PMID:22425726

    Objectives: The impact of different blood pressure (BP) components during the acute stage of stroke on the risk of recurrent stroke is controversial. The present study aimed to investigate by 24 hour BP monitoring a possible association between acute BP values and long term recurrence. Methods: A total of 339 consecutive patients with first ever acute stroke underwent 24 hour BP monitoring within 24 hours of ictus. Known stroke risk factors and clinical findings on admission were documented. Patients given antihypertensive medication during BP monitoring were excluded. The outcome of interest during the one year follow up was recurrent stroke. The Cox proportional hazard model was used to analyse association of casual and 24 hour BP recordings with one year recurrence after adjusting for stroke risk factors, baseline clinical characteristics, and secondary prevention therapies. Results: The cumulative one year recurrence rate was 9.2% (95% CI 5.9% to 12.3%). Multivariate Cox regression analyses revealed age, diabetes mellitus, and 24 hour pulse pressure (PP) as the only significant predictors for stroke recurrence. The relative risk for one year recurrence associated with every 10 mm Hg increase in 24 hour PP was 1.323 (95% CI 1.019 to 1.718, p = 0.036). Higher casual PP levels were significantly related to an increased risk of one year recurrence on univariate analysis, but not in the multivariate Cox regression model. Conclusions: Elevated 24 hour PP levels in patients with acute stroke are independently associated with higher risk of long term recurrence. Further research is required to investigate whether the risk of recurrent stroke can be reduced to a greater extent by decreasing the pulsatile component of BP in patients with acute stroke.

    Background: The mumps virus is frequently the causative agent of parotitis. There has been no study on serum cytokine levels of acute mumps parotitis except for a few which document cytokine levels in cerebrospinal fluid of mumps meningitis. It is with this notion, our study aimed to find Th1/Th2 cytokine levels from patients with acute mumps parotitis. Materials and Methods: Concentrations of mumps-specific IgM, mumps, measles, rubella-specific IgG antibody, and Th1/Th2 cytokines, namely interferon-γ (IFN-γ), interleukin-2 (IL-2), IL-4, and IL-10 were measured simultaneously in serum from 74 patients (42 pediatric and 32 adult cases), 40 healthy subjects (20 pediatric and 20 adults) and in the supernatant of peripheral blood mononuclear cells stimulated with mumps virus genotype C which served as the positive control. Statistical significance was analyzed between each group by means of Mann–Whitney U-test, Kruskal–Wallis test, and Spearman's rank correlation coefficient test. Results: IgM positivity confirmed acute infection in all 74 patients and of these 67 were vaccinated cases; however, very few of them (10/67) were positive for mumps IgG. We found that IFN-γ, IL-2, and IL-10 showed a statistically significant increase in both pediatric and adult patients with acute mumps infection when compared to healthy controls and values were comparable to the positive control. Conclusion: The Th1 cells play important roles during the acute phase of mumps parotitis. PMID:27293364

    Wandering spleen is a very rare defect characterized by the absence or weakness of one or more of the ligaments that hold the spleen in its normal position in the upper left abdomen. Patient symptomatology is variable and ranges from mere feeling of an abdominal lump to sudden abdominal pain due to infarction. Patients may have subacute to chronic abdominal or gastrointestinal complaints. Because of nonspecific symptoms, clinical diagnosis can be difficult; hence, imaging plays an important role. A major complication is splenic torsion, which is the cause of acute abdomen. We present a case of acute abdominal pain due to torsion of wandering spleen in a patient with Marfan Syndrome, valvular heart disease, and vertebral anomalies. Preoperative diagnosis was made on the basis of ultrasonography and computed tomography, which was later confirmed on surgery, and treated successfully.

    The aim of the present study was to quantify the severity of acute illness in patients with tick-borne encephalitis and to ascertain this approach by comparing it to standard clinical assessment. We designed scoring system for quantification of the severity of acute illness in patients with tick-borne encephalitis. Certain number of points was allotted to the presence, intensity, and duration of individual symptoms/signs. According to the obtained score the disease was classified as mild, moderate, and severe. Tick-borne encephalitis was assessed clinically as mild when only signs/symptoms of meningeal involvement were found, moderate in case of monofocal neurological signs and/or mild to moderate signs/symptoms of central nervous system dysfunction, and severe in patients with multifocal neurological signs and/or symptoms of severe dysfunction of central nervous system. By designed scoring system 282 adult patients, 146 males and 136 females, average aged 52.2 ± 15.5 years (range 15–82 years), with confirmed tick-borne encephalitis, were prospectively assessed. In 279/282 (98.9%) patients the severity according to clinical assessment matched with the score ranges for mild, moderate, and severe disease. The proposed approach enables precise and straightforward appraisal of the severity of acute illness and could be useful for comparison of findings within/between study groups. PMID:24895617

    The use of intravenous thrombolytic therapy for acute ischemic stroke is associated with improved outcomes. Fabry disease is an X-linked glycosphingolipid storage disease with vascular endothelial deposits. Affected males with the classic phenotype develop renal, cardiac, and cerebrovascular disease and die prematurely. However, Fabry disease is rare in young men with first ischemic stroke of undetermined cause. We report a 38-year-old man with acute aphasia and a left M2 segment of the middle cerebral artery thrombus with no recanalization who was finally diagnosed with Fabry disease after left ventricular hypertrophy of undetermined cause had been identified. A gene test revealed a R227X mutation typical of Fabry disease with the classical phenotype. To our knowledge our patient is the first reported male Fabry patient who was given intravenous thrombolytic therapy and the first reported Fabry patient who received intravenous thrombolytic therapy between 3 and 4.5 hours of the symptom onset. Despite favorable prognostic indicators on admission imaging, our patient suffered a significant stroke and had an unfavorable clinical outcome. Fortunately, the episode was not complicated by intracranial hemorrhage. Further studies are needed to evaluate the efficacy and safety of intravenous thrombolytic therapy in treating patients with Fabry disease and acute ischemic stroke.

    OBJECTIVE: To evaluate the outcomes of acute myeloid leukemia patients who were older than 60 years of age at the time of diagnosis following the implementation of a treatment algorithm based on age, performance status, and cytogenetic results. METHODS: We retrospectively compared the results of 31 elderly acute myeloid leukemia patients (median age of 74 years) who were treated according to the new algorithm. RESULTS: Fifteen patients with a good performance status and no unfavorable karyotypes were treated with either intensive cytotoxic chemotherapy (<70 years, nine cases) or adapted etoposide, 6-thioguanine and idarubicine (>70 years, six cases); 16 cases with a poor performance status or unfavorable cytogenetics received supportive care only. Six patients achieved a complete remission and two achieved a partial remission after chemotherapy. There were three toxic deaths during induction, two in the adapted etoposide, 6-thioguanine and idarubicine group and one in the intensive cytotoxic chemotherapy group. The overall median survival time was 2.96 months, 1.3 months in the supportive care group, and 4.6 months in the treatment group. CONCLUSIONS: Our results illustrate the importance of treatment guidelines adapted to local resources in an attempt to improve the survival of elderly acute myeloid leukemia patients in developing countries.

    Background. In acute coronary syndrome (ACS), inflammation and redox response are associated with increased residual platelet reactivity (RPR) on clopidogrel therapy. We investigated whether clopidogrel interaction affects platelet function and modulates factors related to inflammation and oxidation in ACS patients differently responding to clopidogrel. Material and Methods. Platelet aggregation was measured in 29 ACS patients on dual (aspirin/clopidogrel) antiplatelet therapy. Nonresponders (NR) were defined as RPR ≥70% by ADP. Several inflammatory and redox parameters were assayed and platelet proteome was determined. Results. Eight (28%) out of 29 ACS patients resulted NR to clopidogrel. At 24 hours, the levels of Th2-type cytokines IL-4, IFNγ, and MCP-1 were higher in NR, while blood GSH (r-GSHbl) levels were lower in NR than responders (R). Proteomic analysis evidenced an upregulated level of platelet adhesion molecule, CD226, and a downregulation of the antioxidant peroxiredoxin-4. In R patients the proinflammatory cytokine IL-6 decreased, while the anti-inflammatory cytokine IL-1Ra increased. Conclusions. In patients with high RPR on clopidogrel therapy, an unbalance of inflammatory factors, platelet adhesion molecules, and circulatory and platelet antioxidant molecules was observed during the acute phase. Proinflammatory milieu persists in nonresponders for a long time after the acute event while antioxidant blood factors tend to conform to normal responsiveness. PMID:25873769

    Objectives Acute kidney injury is a frequent complication of cardiac surgery and increases morbidity and mortality. As preoperative biomarkers predicting the development of acute kidney injury are not available, we have tested the hypothesis that preoperative plasma levels of endogenous ouabain may function as this type of biomarker. Rationale and Design Endogenous ouabain is an adrenal stress hormone associated with adverse cardiovascular outcomes. Its involvement in acute kidney injury is unknown. With studies in patients and animal settings, including isolated podocytes, we tested the above mentioned hypothesis. Patients Preoperative endogenous ouabain was measured in 407 patients admitted for elective cardiac surgery and in a validation population of 219 other patients. We also studied the effect of prolonged elevations of circulating exogenous ouabain on renal parameters in rats and the influence of ouabain on podocyte proteins both “in vivo” and “in vitro.” Main Results In the first group of patients, acute kidney injury (2.8%, 8.3%, 20.3%, p < 0.001) and ICU stay (1.4 ± 0.38, 1.7 ± 0.41, 2.4 ± 0.59 days, p = 0.014) increased with each incremental preoperative endogenous ouabain tertile. In a linear regression analysis, the circulating endogenous ouabain value before surgery was the strongest predictor of acute kidney injury. In the validation cohort, acute kidney injury (0%, 5.9%, 8.2%, p < 0.0001) and ICU stay (1.2 ± 0.09, 1.4 ± 0.23, 2.2 ± 0.77 days, p = 0.003) increased with the preoperative endogenous ouabain tertile. Values for preoperative endogenous ouabain significantly improved (area under curve: 0.85) risk prediction over the clinical score alone as measured by integrate discrimination improvement and net reclassification improvement. Finally, in the rat model, elevated circulating ouabain reduced creatinine clearance (–18%, p < 0.05), increased urinary protein excretion (+ 54%, p < 0.05), and reduced expression of podocyte nephrin

    In patients with acute coronary syndromes undergoing percutaneous coronary intervention (PCI), the diagnosis of periprocedural myocardial infarction is often problematic when the pre-PCI levels of cardiac troponin T (TnT) are elevated. Thus, we examined different TnT criteria for periprocedural myocardial infarction when the pre-PCI TnT levels were elevated and also the associations between the post-PCI cardiac marker levels and outcomes. We established the relation between the post-PCI creatine kinase-MB (CKMB) and TnT levels in 582 patients (315 with acute coronary syndromes and 272 with stable coronary heart disease). A post-PCI increase in the CKMB levels to 14.7 μg/L (3 × the upper reference limit [URL] in men) corresponded to a TnT of 0.23 μg/L. In the 85 patients with acute coronary syndromes and normal CKMB, but elevated post peak TnT levels before PCI (performed at a median of 5 days, interquartile range 3 to 7), the post-PCI cardiac marker increases were as follows: 21 (24.7%) with a ≥ 20% increase in TnT, 10 (11.8%) with an CKMB level >3 × URL, and 12 (14%) with an absolute TnT increase of >0.09 μg/L (p <0.005 for both). In the patients with stable coronary heart disease and post-PCI cardiac markers > 3× URL compared to those without markers elevations, the rate of freedom from death or nonfatal myocardial infarction was 88% for those with TnT elevations versus 99% (p <0.001, log-rank) and 84% for those with CKMB elevations versus 98% (p <0.001, log-rank). Of the patients with acute coronary syndromes, the post-PCI marker levels did not influence the outcomes. In conclusion, in patients with acute coronary syndromes and elevated TnT levels undergoing PCI several days later, ≥20% increases in TnT were more common than absolute increments in the TnT or CKMB levels of >3× URL. Also, periprocedural cardiac marker elevations in patients with acute coronary syndromes did not have prognostic significance.

    Delusional misidentification syndromes are a group of delusional phenomena in which patients misidentify familiar persons, objects, or themselves, believing that they have been replaced or transformed. In 25%–40% of cases, misidentification syndromes have been reported in association with organic illness. We report an acute episode of Capgras-like delusion lasting 8 days, focused on the idea that people were robots with human bodies, in association with an acute urinary infection. To our knowledge, this is the first case report associating urinary tract infection with Capgras-like syndrome. Awareness of the prevalence of delusional misidentification syndromes associated with acute medical illness should promote diligence on the part of clinicians in recognizing this disorder.

    Intubation is necessary in 7 to 20% of patients with severe acute cardiogenic pulmonary oedema despite optimal treatment. This study evaluated the usefulness of parameters largely available in clinical practice to predict the need for intubation in a population of acute cardiogenic pulmonary oedema patients treated with medical therapy and continuous positive airway pressure. The present retrospective cohort study involved 142 patients with severe acute cardiogenic pulmonary oedema who were admitted to coronary care or the intensive care unit of a university hospital and were treated by an in-hospital protocol. Physiological measurements and blood gas samples were evaluated at 'baseline' (just after admission), 'early' (one to three hours after beginning treatment) and 'late' (eight to 10 hours after beginning treatment). Twenty-two patients (15.5%) required intubation. A systolic blood pressure at admission lower than 140 mmHg was significantly associated with a higher risk for intubation, while hypercapnic patients or those with a reduced left ventricular ejection fraction at admission did not show a worse prognosis. A simple score based on largely available parameters (1 point for each: age >78 years, systolic blood pressure <140 mmHg at admission, arterial blood gas acidosis and heart rate >95 bpm at early time) is proposed. The rate of intubation according to this score ranged from 0% (score of 0) to 90% (score of 3). Our study found that simple parameters available in clinical practice are significantly associated with the need for intubation in acute cardiogenic pulmonary oedema patients treated with continuous positive airway pressure and medical therapy. A simple score to evaluate the need for endotracheal intubation is proposed.

    Learning and the formation of memory are reflected in various memory systems in the human brain such as the hippocampus based declarative memory system and the striatum-cortex based system involved in motor sequence learning. It is a matter of debate how both memory systems interact in humans during learning and consolidation and how this interaction is influenced by sleep. We studied the effect of an acute dysfunction of hippocampal CA1 neurons on the acquisition (on-line condition) and off-line changes of a motor skill in patients with a transient global amnesia (TGA). Sixteen patients (68 ± 4.4 yrs) were studied in the acute phase and during follow-up using a declarative and procedural test, and were compared to controls. Acute TGA patients displayed profound deficits in all declarative memory functions. During the acute amnestic phase, patients were able to acquire the motor skill task reflected by increasing finger tapping speed across the on-line condition, albeit to a lesser degree than during follow-up or compared to controls. Retrieval two days later indicated a greater off-line gain in motor speed in patients than controls. Moreover, this gain in motor skill performance was negatively correlated to the declarative learning deficit. Our results suggest a differential interaction between procedural and declarative memory systems during acquisition and consolidation of motor sequences in older humans. During acquisition, hippocampal dysfunction attenuates fast learning and thus unmasks the slow and rigid learning curve of striatum-based procedural learning. The stronger gains in the post-consolidation condition in motor skill in CA1 lesioned patients indicate a facilitated consolidation process probably occurring during sleep, and suggest a competitive interaction between the memory systems. These findings might be a reflection of network reorganization and plasticity in older humans and in the presence of CA1 hippocampal pathology.

    It is important for caregivers and patients to know which wounds are at risk of prolonged wound healing to enable timely communication and treatment. Available prognostic models predict wound healing in chronic ulcers, but not in acute wounds, that is, originating after trauma or surgery. We developed a model to detect which factors can predict (prolonged) healing of complex acute wounds in patients treated in a large wound expertise centre (WEC). Using Cox and linear regression analyses, we determined which patient- and wound-related characteristics best predict time to complete wound healing and derived a prediction formula to estimate how long this may take. We selected 563 patients with acute wounds, documented in the WEC registry between 2007 and 2012. Wounds had existed for a median of 19 days (range 6-46 days). The majority of these were located on the leg (52%). Five significant independent predictors of prolonged wound healing were identified: wound location on the trunk [hazard ratio (HR) 0·565, 95% confidence interval (CI) 0·405-0·788; P = 0·001], wound infection (HR 0·728, 95% CI 0·534-0·991; P = 0·044), wound size (HR 0·993, 95% CI 0·988-0·997; P = 0·001), wound duration (HR 0·998, 95% CI 0·996-0·999; P = 0·005) and patient's age (HR 1·009, 95% CI 1·001-1·018; P = 0·020), but not diabetes. Awareness of the five factors predicting the healing of complex acute wounds, particularly wound infection and location on the trunk, may help caregivers to predict wound healing time and to detect, refer and focus on patients who need additional attention.

    Background Circulating osteoprotegerin (OPG) levels are increased in patients with chronic heart failure (HF). The diagnostic and prognostic merit of OPG measurement in patients admitted with acute dyspnoea is unknown. Objectives To evaluate the diagnostic and prognostic value of measuring OPG in patients admitted to hospital with acute dyspnoea. Methods OPG was analysed by ELISA in 308 patients admitted due to acute dyspnoea. Investigators blinded to OPG results adjudicated the diagnosis for the index hospitalization. Clinical outcomes were obtained from hospital records. Results In total, 139 patients (45%) were hospitalized with acute HF. OPG levels on hospital admission were higher in patients with acute HF vs. no acute HF, 7.8 (5.5–10.4) vs. 5.4 (3.8–7.2) pmol/L, p<0.001. The area under the receiver operator characteristic curve (ROC AUC) of OPG to discriminate between HF vs. non-HF was 0.695 [95% CI 0.636–0.754]. OPG did not provide incremental information to the ED physician’s prediction or N-terminal pro-B-type natriuretic peptide regarding the diagnosis of acute HF. OPG levels (log transformed) were associated with mortality in crude analysis (HR (95% CI) 1.87 (1.34 to 2.61), p<0.001), but this association was attenuated and no longer significant after including established cardiac biomarkers into the model. Conclusion In patients admitted to hospital with acute dyspnoea, OPG levels are higher in patients with acute HF than in those with dyspnoea from other causes. However, OPG does not provide incremental information beyond ED physician assessment for the diagnosis of acute HF or beyond clinical risk variables and established cardiac biomarkers concerning prognosis.

    118 patients who had recovered from acute pancreatitis underwent endoscopic retrograde pancreatography (ERCP) during a long-term follow-up (mean 4.4 years, range 1-17) to investigate the frequency and features of residual ductal lesions. Oedematous and necrohaemorrhagic pancreatitis occurred in 35 and in 83 patients, respectively. The aetiology was biliary (39 patients), alcoholic (32), biliary-alcoholic (18) and miscellaneous (29). After oedematous pancreatitis, ERCP was normal in 31, showed obstructive pancreatitis in 2 and a slight localized and smooth stricture of the main duct in 2 patients. After necrotizing pancreatitis, 29 patients showed ductal changes without features of chronic pancreatitis, 7 obstructive, 3 chronic calcifying pancreatitis and 44 normal pictures. In 17 patients submitted to two or three ERCPs during a mean 10-year follow-up, the ductal appearance was unchanged in 12, worsened in 3, and improved in 2 patients. The aetiology of pancreatitis and frequency of recurrences was similar in patients with or without scarring lesions. We conclude that residual ductal lesions are common after acute necrotizing pancreatitis.

  5. Graduated compression stockings to prevent venous thromboembolism in hospital: evidence from patients with acute stroke.

    Pulmonary embolism is the most common preventable cause of death in hospital patients and prevention of venous thromboembolism (VTE) is cost-saving in high-risk patients. Low-dose anticoagulation is very effective at preventing VTE but increases bleeding. Graduated compression stockings and intermittent pneumatic compression devices are also used to prevent VTE and do not increase bleeding, which makes their use appealing in patients who cannot tolerate bleeding, such as patients with acute stroke. Studies that evaluated mechanical methods of preventing VTE were small and mainly used asymptomatic deep vein thrombosis (DVT), detected using screening tests, as the study outcome. The recently published CLOTS Trial 1 (Clots in Legs Or sTockings after Stroke) compared thigh-level compression stockings with no stockings in about 2500 patients with stroke and immobility, and found that thigh-level stockings were not effective. Indirectly, the findings of this study question the ability of stockings to prevent VTE in other patient groups, including those after surgery. CLOTS 1 compared thigh-level and below-knee stockings in about 3000 patients with acute stroke. Given that thigh-level stockings were ineffective in CLOTS 1, it is surprising that they were more effective than below-knee stockings in CLOTS Trial 2. A possible explanation is that below-knee stockings increase DVT, although this seems unlikely. CLOTS 1 and CLOTS 2 question whether graduated compression stockings prevent VTE and suggest the need for further trials evaluating their efficacy in medical and surgical patients.

    OBJECTIVE: We studied the relationship between acute pancreatitis and organ failure in African-American and Hispanic patients. METHODS: The medical records of 760 (417 African-American and 343 Hispanic) patients aged 19-85 years diagnosed with acute pancreatitis over 15 years were reviewed retrospectively. We abstracted and analyzed data related to demographics, etiology, type of pancreatitis, organ failure and mortality. RESULTS: Of the 760 patients, 24% had organ failure. Of the 182 patients with organ failure, 125 patients (69%) had multiple organ failure, whereas 57 patients (31%) had single type. Cardiovascular system failure was the common organ dysfunction (28%). Of the 760 patients, 14% died. Patients with organ failure had a higher mortality (40%) compared with those without it (6%) (OR=9.6, 95% CI: 6.0-15.3) (P=0.001). Mortality was higher among those with multiple organ failure (46%) compared with those with single type (25%). Mortality was highest among those with pulmonary failure (57%). CONCLUSION: The prevalence of organ failure in our study was slightly higher than the general population (20%). Mortality from single type was higher than that reported in previous studies (8-11%), especially mortality from pulmonary failure (18%). Prevention, early diagnosis and prompt treatment of organ failure may improve the clinical outcome. PMID:18229777

    2014-03-01

    Diagnosis of acute heart failure (HF) is difficult in elderly patients with multiple comorbidities. Risk scales and classification criteria based exclusively on clinical manifestations, such as the Framingham scales, lack sufficient specificity. In addition to clinical manifestations, diagnosis should be based on two key factors: natriuretic peptides and echocardiographic study. When there is clinical suspicion of acute HF, a normal natriuretic peptide level will rule out this process. When a consistent clinical suspicion is present, an echocardiographic study should also be performed. Diagnosis of HF with preserved ejection fraction (HF/pEF) requires detection of an enlarged left atrium or the presence of parameters of diastolic dysfunction. Elevation of cardiac biomarkers seems to be due to myocardial injury and the compensatory mechanisms of the body against this injury (hormone and inflammatory response and repair mechanisms). Elevation of markers of cardiac damage (troponins and natriuretic peptides) have been shown to be useful both in the diagnosis of acute HF and in prediction of outcome. MMP-2 could be useful in the diagnosis of HF/pEF. In addition to biomarkers with diagnostic value, other biomarkers are helpful in prognosis in the acute phase of HF, such as biomarkers of renal failure (eGFR, cystatin and urea), inflammation (cytokines and CRP), and the cell regeneration marker, galectin-3. A promising idea that is under investigation is the use of panels of biomarkers, which could allow more accurate diagnosis and prognosis of acute HF.

    The patients with hematologic malignancies are predisposed to develop infections with unusual bacteria, like Burkholderia cepacia, which is frequently resistant to many antibiotics and antiseptics. We present the case of a female patient with acute myeloid leukemia type 2 on the background of myelodysplastic syndrome, from whom Burkholderia cepacia was isolated in blood culture, after the 2nd cycle of induction. She was sensitive to ceftazidime, but its eradication was not easy. Five other patients were contaminated with this bacteria, but all of them had favourable evolution. The case is discussed in the context of those similar in literature. PMID:24353735

    The authors describe a 28-year-old woman with newly diagnosed acute promyelocytic leukaemia (APL), who developed junctional bradycardia after receiving the molecular-targeted therapy all-trans retinoic acid (ATRA) and the anthracycline-based chemotherapeutic agent idarubicin following sepsis and the APL differentiation syndrome. The patient was asymptomatic of the bradycardia. Electrolytes and cardiac imaging were unremarkable. No other cases have been reported in this context and the mechanisms of the sinus node dysfunction are unclear. The patient achieved normal sinus rhythm after ATRA was withheld. The patient recovered and went on to achieve complete remission after re-starting ATRA and idarubicin.

    Differentiation syndrome (DS) is a life-threatening complication observed in patients with acute promyelocytic leukemia (APL) receiving induction therapy with all-trans-retinoic acid (ATRA). A bimodal incidence of DS has been observed, with a majority of cases occurring during the first week of ATRA treatment ("early" DS), but a substantial number of cases occurring during the third or even fourth week of ATRA treatment ("late" DS). However, to our knowledge occurrence of both early and late DS in the same patient has not been reported. We report an APL patient treated with the AIDA regimen, who experienced both early and late DS, a situation where differential diagnosis was difficult.

    To determine the significance of patients' age and sex on the size of the thrombus in acute deep vein thrombosis, 420 consecutive phlebograms with acute deep vein thrombosis were studied. A significant correlation between the size of the thrombus and increasing age of the patient as well as the sex of male was noted. It is concluded that older patients and men often are at a high risk of pulmonary embolism at the time of diagnosis.

    Stroke has a greater effect on women than men owing to the fact that women have more stroke events and are less likely to recover. Age-specific stroke rates are higher in men; however, because of women's longer life expectancy and the much higher incidence of stroke at older ages, women have more stroke events than men overall. The aims of this prospective study in consecutive patients were to assess whether there are gender differences in stroke risk factors, treatment or outcome. Consecutive patients with ischemic stroke were included in this prospective study at four study centers. Disability was assessed using a modified Rankin Scale score (>or=3 indicating disabling stroke) in both genders at 90 days. Outcomes and risk factors in both genders were compared using the chi(2) test. Multiple logistic regression analysis was used to identify any independent predictors of outcome. A total of 1136 patients were included in this study; of these, 494 (46%) were female. Women were statistically older compared with men: 76.02 (+/- 12.93) and 72.68 (+/- 13.27) median years of age, respectively. At admission, females had higher NIH Stroke Scale scores compared with males (9.4 [+/- 6.94] vs 7.6 [+/- 6.28] for men; p = 0.0018). Furthermore, females tended to have more cardioembolic strokes (153 [30%] vs 147 [23%] for men; p = 0.004). Males had lacunar and atherosclerotic strokes more often (146 [29%] vs 249 [39%] for men; p = 0.002, and 68 [13%] vs 123 [19%] for men; p = 0.01, respectively). The mean modified Rankin Scale score at 3 months was also significantly different between genders, at 2.5 (+/- 2.05) for women and 2.1 (+/- 2.02) for men (p = 0.003). However, at multivariate analysis, female gender was not an indicator for negative outcome. It was concluded that female gender was not an independent factor for negative outcome. In addition, both genders demonstrated different stroke pathophysiologies. These findings should be taken into account when diagnostic workup and

    Background Little research has focused on the economic hardship among the insured with severe illnesses and high treatment costs, in particular, the consequence of poorer insurance coverage for high-cost illnesses. Therefore, we presented the case for identifying the experiences of insured patients with severe chronic and acute illnesses. This study identified a qualitative understanding of the economic impact of severe chronic and acute illnesses and household strategies to deal with high treatment costs. Design Interviews were conducted with 19 insured households of three different health insurance programs with a family member that had been hospitalized for severe chronic or acute illnesses in either Banyumas or Margono Sukarjo hospitals in Banyumas, Central Java, Indonesia. A thematic analysis was applied to guide the interpretation of the data. Results Insured households with a family member that had been hospitalized for severe chronic and acute illnesses were greatly affected by the high treatment costs. Four major issues emerged from this qualitative study: insured patients are still burdened with high out-of-pocket payments, households adopt various strategies to cope with the high cost of treatments, households experience financial hardships, and positive and negative perceptions of the insured regarding their health insurance coverage for acute and chronic illnesses. Conclusions Askes and Jamsostek patients faced financial burdens from high cost sharing for hospital amenities, non-covered drugs, and treatments and other indirect costs. Meanwhile, Jamkesmas beneficiaries faced no financial burden for related medical services but were rather burdened with indirect costs for the carers. Households relied on internal resources to cover hospital bills as the first strategy, which included the mobilization of savings, sale of assets, and borrowing of money. External support was tapped secondarily and included financial support from extended family members

  16. Evaluation of Lipid Profile Changes in Pediatric Patients with Acute Mononucleosis

    2017-01-01

    Background Acute Epstein-Barr virus (EBV) infection could lead to atherogenic lipid profile changes in adults; while there is no evidence about the children with Infectious mononucleosis (IM). The aim of this study was to evaluate the lipid profile of the children in acute phase of mononucleosis and two months after the recovery. Materials and Methods From 2010 through 2012, 36 children with IM aged 1-10 years were enrolled in a prospective cross-sectional study. Fasting serum total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), and triglyceride level were measured during acute phase of the disease and after 2 months of the recovery. Results From 36 patients enrolled, 25 (69.4%) cases were male and the mean age of the patients was 4.1 ± 2.0 years. The mean of the total cholesterol level in the acute phase and 2 months after the recovery were149.5 ± 35.3 mg/dL and 145.7±30.6, respectively (P = 0.38). However, the serum level of HDL cholesterol in patients after 2 months of recovery was significantly increased (37.9 ± 9.3 mg/dL vs. 28.5 ± 10.6 mg/dL, P <0.001). The mean value of serum LDL cholesterol was significantly reduced, two months after recovery (81.4 ± 19.5 mg/dL, vs. 92.6 ± 28.8 mg/dL, P = 0.009). Furthermore, the serum triglyceride level was significantly reduced after the recovery (108.7 ± 36.9 mg/dL) compared with the acute phase (163.8 ± 114.3 mg/dL) (P = 0.004). Conclusion EBV infection in children could change lipid profile which is partially restored 2 months after the recovery. PMID:28332346

    Nutritional management of acute metabolic decompensation in amino acid inborn errors of metabolism (AA IEM) aims to restore nitrogen balance. While nutritional recommendations have been published, they have never been rigorously evaluated. Furthermore, despite these recommendations, there is a wide variation in the nutritional strategies employed amongst providers, particularly regarding the inclusion of parenteral lipids for protein-free caloric support. Since randomized clinical trials during acute metabolic decompensation are difficult and potentially dangerous, mathematical modeling of metabolism can serve as a surrogate for the preclinical evaluation of nutritional interventions aimed at restoring nitrogen balance during acute decompensation in AA IEM. A validated computational model of human macronutrient metabolism was adapted to predict nitrogen balance in response to various nutritional interventions in a simulated patient with a urea cycle disorder (UCD) during acute metabolic decompensation due to dietary non-adherence or infection. The nutritional interventions were constructed from published recommendations as well as clinical anecdotes. Overall, dextrose alone (DEX) was predicted to be better at restoring nitrogen balance and limiting nitrogen excretion during dietary non-adherence and infection scenarios, suggesting that the published recommended nutritional strategy involving dextrose and parenteral lipids (ISO) may be suboptimal. The implications for patients with AA IEM are that the medical course during acute metabolic decompensation may be influenced by the choice of protein-free caloric support. These results are also applicable to intensive care patients undergoing catabolism (postoperative phase or sepsis), where parenteral nutritional support aimed at restoring nitrogen balance may be more tailored regarding metabolic fuel selection.

    We investigated acute effects of intermittent large dose bisphosphonate therapy in osteoporotic patients. Peripheral blood mononuclear cells were incubated with alendronate (100 microM) for 18 hr, in vitro and cytokine expressions were measured by real-time RT-PCR. Pamidronate 30 mg was administered on 26 osteoporotic patients; and acute phase reactants, inflammatory cytokines and bone biomarkers were measured. The in vitro study showed significant increase in mRNA expression of IL-6, TNF-alpha and IFN-gamma. A notable rise in serum C-reactive protein (CRP) was observed over 3 days after pamidronate infusion (P=0.026). Serum levels of TNF-alpha, IL-6 and IFN-gamma were also significantly increased (P=0.009, 0.014, 0.035, respectively) and the increase in IL-6 levels were strongly correlated with CRP levels (P=0.04). Serum calcium and c-telopeptide levels rapidly decreased after the treatment (P=0.02, <0.001, respectively). This study showed that mRNA expression of inflammatory cytokines at peripheral blood mononuclear cells (PBMC) level were observed within 18 hr and marked elevation of inflammatory cytokines and acute phase reactants were demonstrated after pamidronate infusion at the dose for osteoporosis. Our studies confirmed that intermittent large dose aminobisphosphonate causes acute inflammation.

    Increased morbidity and mortality due to asthma suggested the need to investigate whether persons with asthma report delay in seeking medical care during acute asthma exacerbations and the reasons they gave for delay. We interviewed 95 asthmatic adults, 36 men and 59 women, using a critical incident technique to discover how patients responded to acute asthma symptom episodes. Subjects were interviewed once per month for a total of three interviews. All subjects had physician-diagnosed asthma for a mean of 16.8+/-14.5 years. Eighty-six percent of the sample (n=82) reported delay in seeking medical care for severe asthma symptoms. Seven reasons for delay were identified: uncertainty, disruption, minimization, fear of systemic corticosteroid, previous bad experiences in emergency departments, the need to "tough it out" alone, and economic reasons. Seventy-one subjects (86.5%) reported three or more reasons for delay. Thirteen subjects (16%) identified pivotal episodes in which they realized they could die from asthma and as a result, no longer delayed. People with asthma often delay seeking urgent care for acute episodes for a variety of reasons. Some of these reasons are modifiable. Clear directions from health professionals to guide patients in responding to acute asthma episodes are needed. Asthma action plans written by the primary physician may be a positive agent of change for those who delay.

    The C-reactive protein (CRP), first described as a serum component capable of precipitating the C-polysaccharide of pneumococci, is one of the most important proteins because the serum concentration rises in the acute phase reaction. The acute phase reaction is the nonspecific reaction of the body to noxious stimuli of the most varied kinds, such as infections, burns, neoplasms and tissue trauma. The CRP is synthesized in liver parenchymal cells by cytokines which are derived from stimulated leucocytes and released into the circulation. Because of its molecular structure and in synergy with the complement system, it is able to precipitate and/or lyse microorganisms, thereby rendering them harmless. Measurement of the serum CRP concentration can provide important information with respect to the diagnosis and monitoring of treatment. Due to immunosenescence in geriatric patients the synthesis of CRP appears to be limited to inflammatory stimuli; however, this phenomenon does not appear to be of major clinical relevance. Despite the introduction of new parameters of the acute phase reaction, sometimes with better performance, such as interleukin-6, procalcitonin and the soluble endotoxin receptor sCD14, measurement of CRP for diagnosis and treatment monitoring is still justified even in geriatric patients as testing is rapid, economic and nearly ubiquitously available round the clock. Biochemical markers of the acute phase reaction should always be interpreted together with the clinical picture and their specific limitations.

  1. Is Valproate Depressogenic in Patients Remitting from Acute Mania? Case Series

    PubMed Central

    Sharma, Priya

    2015-01-01

    Valproate is an effective antimanic agent and is recommended as a first-line medication in the treatment of acute mania. Current evidence based guidelines recommend that valproate should be given as a loading dose as it produces a rapid antimanic and antipsychotic response with minimal side-effects. However, no clear guidelines are available on the appropriate dosing or serum levels of valproate in the continuation or maintenance phase of bipolar disorder. We present 4 clinical cases to hypothesize that the higher doses of valproate, such as those used in the treatment of acute mania, may cause a depressive switch. So consideration should be given to reducing the dose of valproate if a patient develops depressive symptoms following recovery from the manic episode, as a therapeutic strategy. The cases also indicate that relatively lower doses and serum levels of valproate are effective in the maintenance phase compared to those needed in the acute manic phase of bipolar disorder. This is the first set of case series that questions the depressogenic potential of valproate in patients remitting from an acute manic episode. It highlights that different doses and serum levels of valproate may be therapeutic in different phases of bipolar disorder. PMID:26664794

    Euforia, a supplement containing a variety of natural ingredients, is widely used as an antioxidant and anti-inflammatory formula. It is not approved by the US Food and Drug Administration and its side effects are unknown. We report a 45-year-old woman with limited systemic sclerosis who presented with jaundice and marked elevation of serum transaminases. One month before, she started taking Euforia juice. A liver biopsy disclosed submassive hepatocellular necrosis with histopathological changes consistent with toxic hepatitis. The patient's symptoms resolved with cessation of Euforia. Six months later, she persisted with abnormal liver function tests, but these resolved 18 months after discontinuation of Euforia. The mechanism by which Euforia causes liver injury is unknown. Some ingredients contained in this supplement (green tea, Aloe vera, noni and goji) are linked to hepatic injury. To our knowledge, this is the first report of hepatotoxicity associated with Euforia.

    2014-01-01

    Introduction In healthy subjects, Cytomegalovirus infection can be asymptomatic or manifest as mononucleosis syndrome, but organ disease has also been reported. However, in immunocompromised patients this infection can lead to its most significant and severe disease and even mortality. When Cytomegalovirus causes a gastrointestinal tract infection, it more commonly manifests with luminal tract disease and is usually characterized by ulcerative lesions. Appendicitis is a rare manifestation, and has been reported mainly in human immunodeficiency virus-infected patients or patients with other causes of immunocompromise. Case presentation The authors report on a case of acute primary Cytomegalovirus infection complicated with acute appendicitis due to Cytomegalovirus in an apparently immunocompetent 24-year-old Caucasian man also suffering from primary sclerosing cholangitis and ulcerative colitis. Diagnosis was based on clinical manifestations, serology results, as well as microbiological and histological findings. Treatment consisted of surgery and anti-Cytomegalovirus therapy. Conclusions Cytomegalovirus should be included among the etiologic agents of acute appendicitis in patients with primary sclerosing cholangitis and ulcerative colitis. Currently, there are no definitive data regarding the frequency of Cytomegalovirus appendicitis and the role of anti-Cytomegalovirus treatment in human immunodeficiency virus-negative and apparently immunocompetent subjects.

    Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related fatalities and is characterized by the onset of acute respiratory distress within six hours following blood transfusion. In most cases, donor antibodies are suggested to be involved, however, the pathogenesis is poorly understood. A two-hit model is generally assumed to underlie TRALI pathogenesis where the first hit consists of a patient predisposing factor such as inflammation and the second hit is due to donor antibodies present in the transfused blood. We recently demonstrated that the acute phase protein C-reactive protein (CRP) could enhance murine anti-major histocompatibility complex (MHC) class I-mediated TRALI. Whether CRP is increased in human TRALI patients which would support its role as a risk factor for human TRALI, is currently unknown. For that purpose, we measured CRP levels in the plasma of human TRALI patients and found CRP levels to be significantly elevated compared to transfused control patients. These data support the notion that CRP may be a novel first hit risk factor in human TRALI and that modulation of CRP levels could be an effective therapeutic strategy for this serious adverse event of transfusion.

    Physiotherapist in Chile and Respiratory Therapist worldwide are the professionals who are experts in respiratory care, in mechanical ventilation (MV), pathophysiology and connection and disconnection criteria. They should be experts in every aspect of the acute respiratory failure and its management, they and are the ones who in medical units are able to resolve doubts about ventilation and the setting of the ventilator. Noninvasive mechanical ventilation should be the first-line of treatment in acute respiratory failure, and the standard of care in severe exacerbations of chronic obstructive pulmonary disease, acute cardiogenic pulmonary edema, and in immunosuppressed patients with high levels of evidence that support the work of physiotherapist. Exist other considerations where most of the time, physicians and other professionals in the critical units do not take into account when checking the patient ventilator synchrony, such as the appropriate patient selection, ventilator selection, mask selection, mode selection, and the selection of a trained team in NIMV. The physiotherapist needs to evaluate bedside; if patients are properly connected to the ventilator and in a synchronously manner. In Chile, since 2004, the physioterapist are included in the guidelines as a professional resource in the ICU organization, with the same skills and obligations as those described in the literature for respiratory therapists.

    Trichloroisocyanuric acid is a high-efficiency and-low toxicity fungicide and bleach. It is commonly used as disinfectant for industrial circulating water, swimming pools, restaurants, and other public places in China. When trichloroisocyanuric acid is put into water, chlorine gas is produced. Chlorine gas is a potent pulmonary irritant that causes acute damage in both the upper and lower respiratory tracts (J Toxicol Clin Toxicol. 1998;36(1-2):87-93). Pneumomediastinum is a rare complication in patients with acute chlorine gas poisoning. A small amount of gas can be asymptomatic, but a large amount of gas entering the mediastinum suddenly will lead to respiratory and circulatory disorder, mediastinal swing, or even cardiopulmonary arrest. Severe chlorine gas poisoning patients usually need mechanical ventilation; if the pneumomediastinum is not found on time, threat to life would be greatly increased. It requires a high index of suspicion for diagnosis and rapid treatment. The proper use of ventilator, timely and effective treatment of original disease, and multiple system organ support had significant impact on the prognosis. The pneumomediastinum case secondary to inhalation of chlorine gas that we report here should remind all emergency department physicians to maintain a high index of suspicion for this disease and seek immediate and proper intervention when treating patients with acute chlorine gas poisoning, once diagnosed, especially in younger patients.

    The All Patient Refined-Diagnostic Related Group (APR-DRG) is a modification of the traditional DRG that adds four classes of illness severity and four classes of mortality risk. The APR-DRG is a more accurate assessment of the complexity of care. When individuals with advanced illness are admitted to an acute inpatient palliative medicine unit, there may be a perception that they receive less intense acute care. Most of these patients, however, are multisymptomatic, have several comorbidities, and are older. For all patients admitted to the unit, a guide was followed by staff physicians to document clinical information that included the site(s) of malignancy, site(s) of metastases, disease complications, disease-related symptoms, and comorbidities. We then prospectively compared DRGs, APR-DRGs, and case mix index (CMI) from January 1-June 30, 2003, and February 1-July 31,2004, before and after the use of the guide. The overall mean severity of illness (ASOI) increased by 25% (P < 0.05). The mean CMI increased by 12% (P < 0.05). The average length of stay over the same period increased slightly from 8.97 to 9.56 days. Systematic documentation of clinical findings using a specific tool for patients admitted to an acute inpatient palliative medicine unit based on APR-DRG classifications captured a higher severity of illness and may better reflect resource utilization.

    Extent of cerebellar involvement in cognition and emotion is still a topic of ongoing research. In particular, the cerebellar role in humor processing and control of laughter is not well known. A hypermetric dysregulation of affective behavior has been assumed in cerebellar damage. Thus, we aimed at investigating humor comprehension and appreciation as well as the expression of laughter in 21 patients in the acute or subacute state after stroke restricted to the cerebellum, and in the same number of matched healthy control subjects. Patients with acute and subacute cerebellar damage showed preserved comprehension and appreciation of humor using a validated humor test evaluating comprehension, funniness and aversiveness of cartoons ("3WD Humor Test"). Additionally, there was no difference when compared to healthy controls in the number and intensity of facial reactions and laughter while observing jokes, humorous cartoons, or video sketches measured by the Facial Action Coding System. However, as depression scores were significantly increased in patients with cerebellar stroke, a concealing effect of accompanying depression cannot be excluded. Current findings add to descriptions in the literature that cognitive or affective disorders in patients with lesions restricted to the cerebellum, even in the acute state after damage, are frequently mild and might only be present in more sensitive or specific tests.

    Introduction: Ghrelin is a novel brain-gut peptide hormone consisted of 28 amino-acid. In the plasma, it exists in two major molecular forms, acylated and des-acyled ghrelin, filtered in glomeruli or secreted by nephrons. Primary biological effects of hormones are regulating appetite, foods intake and energy metabolism. We investigated the changing and relationships between serum and urine ghrelin levels in acute stroke patients to provide more information whether diagnostic parameter. Methods: Thirty acute stroke patients and thirty consecutive volunteers included in study prospectively. To analyze serum and urine ghrelin levels, at the time of diagnose, all of participant blood and fresh urine (1 ml serum, 2 ml urine respectively) samples were obtained. Serum ghrelin levels analyzed ELISA technique, and urine ghrelin levels studied by validation technique. To compare quantitative data student’s t test, and for qualitative data chi-square and Fisher’s Exact Chi-square test was used. P<0.05 was considered statistically significant. Results: Urine acyl ghrelin levels found statistically significant between patient and control groups (P=0.001), but there were no statistically significant differences between both groups (P>0.05) in serum acyl gherelin, des-acyl ghrelin and urine des-acyle ghrelin levels. Conclusions: The results indicate that urine acyl ghrelin levels may be considered as a diagnostic parameter in acute ischemic stroke patients. Further studies delineating the mechanism of these observed results are warranted. PMID:25785049

    Patients with acute liver failure (ALF) are treated on the general intensive care unit (ICU) within this regional centre for hepatology and liver transplantation. This group of patients are at high risk of developing cerebral oedema, but because of the associated coagulopathy, intracranial pressure is not measured invasively. The safe management of these patients is vital to their outcome, and yet, there is no national or local guidance on the best practice for this group of patients. An absence of guidelines, or evidence base specific to caring for hepatology patients, was highlighted as we reviewed local clinical practices and those at other liver specialty centres, the British Liver Trust and published literature. We identified a need to develop evidence-based guidance for staff caring for patients with ALF within ICUs. A systematic approach enabled us to identify best practice to support the development of a structured evidence-based approach to care.

    Fifty-eight adult patients with acute leukemia were screened at the onset of the disease for hepatitis B antigen (HBSAg) in the serum, and during the course of the disease for the development of hepatitis B. One patient had a positive test for HBSAg by the radioimmunoassay technique only at the time leukemia was diagnosed; this patient had received transfusions some years before. In six patients icteric hepatitis B developed; five recovered completely and one died of leukemia during the course of hepatitis. All patients in whom hepatitis developed had received transfusions as a part of supportive therapy for leukemia. The hepatitis risk for patients who received transfusions of blood found to be negative for HBSAg by counterimmunoelectrophoresis was 0.26 percent per unit of blood administered. PMID:1054615

    Fifty-five patients with angiographically proved coronary artery disease (CAD) underwent Bruce protocol exercise stress testing with thallium-201 imaging. Twenty-seven patients (group I) showed myocardial hypoperfusion without angina pectoris during stress, which normalized at rest, and 28 patients (group II) had a similar pattern of reversible myocardial hypoperfusion but also had angina during stress. Patients were followed for at least 30 months. Six patients in group I had an acute myocardial infarction (AMI), 3 of whom died, and only 1 patient in group II had an AMI (p = 0.05), and did not die. Silent myocardial ischemia uncovered during exercise stress thallium testing may predispose to subsequent AMI. The presence of silent myocardial ischemia identified in this manner is of prognostic value, independent of angiographic variables such as extent of CAD and left ventricular ejection fraction.

    The Wnt-LPR5 signalling pathway plays an important role in skeletal homeostasis, especially in regulating osteoblastic activity. Activation of this pathway is regulated by various inhibitors, including DKK1. The objective of this study was to evaluate DKK1 levels in patients with ischemic heart disease, the response to atorvastatin and the relationship with bone mass. Twenty-one patients with acute myocardial infarction and twenty-three controls with a mean age of 61 ± 9 years with acute coronary syndrome were included. Patients were allocated to low (10-20mg) and high doses (40-80 mg) of atorvastatin according to baseline levels of cholesterol and triglycerides and the index of vascular risk. Patients were studied at hospital admission (baseline) and at 12 months of follow up. DKK1 was determined in all patients at baseline and at 12 months of follow up. Densitometric studies were conducted in the lumbar spine (L2-L4) and the femoral neck and trochanter using an X-ray densitometer. Patients had higher levels of DKK1 than controls, (111 ± 41 nmol/l versus 84 ± 27 nmol/l, p=0.014). Osteoporotic patients had higher levels of DKK1 (137.5 ± 33 nmol/l versus 95.4 ± 36 nmol/l, p=0.021). Analysis of the response to atorvastatin showed reduced DKK1 levels. In conclusion, in patients with acute coronary syndrome, atorvastatin decreases DKK1 levels. This may be a previously unreported mechanism of action of atorvastatin on bone, stimulating the Wnt signalling pathway and increasing bone mass.

    This prospective study investigated whether plasma asymmetric dimethylarginine (ADMA) concentrations are related to cardiovascular events in patients with acute heart failure. It has been reported that increased plasma ADMA concentrations are associated with adverse cardiovascular outcome in chronic heart failure. In 118 patients with acute decompensated heart failure and impaired left ventricular function, ADMA and N-terminal pro-brain natriuretic peptide (NT-proBNP) were assessed by high-performance liquid chromatography and by an enzyme-linked immunosorbent assay, respectively. Venous blood was collected at admission and after 1 week, and clinical events were observed during follow-up. All patients (median age 73 years, 96 males) were followed up for a median of 10.7 months. A clinical endpoint (cardiac decompensation, major adverse cardiovascular event, or all-cause mortality) occurred in 66 patients. In 81 patients, changes (Delta) in ADMA or NT-proBNP between admission and a median of 7 days were available. ADMA, NT-proBNP at admission, and DeltaADMA or DeltaNT-proBNP were comparable in patients with and without a clinical endpoint. In contrast to ADMA, NT-proBNP concentrations above the median were associated with higher adjusted hazard ratio for occurrence of an endpoint (HR 2.1; 95% confidence interval 1.2-3.9; P = 0.013). An inverse relationship was observed between DeltaNT-proBNP and endpoints before (P = 0.010) and after (P = 0.015) adjustment for confounders. In patients with acute heart failure, ADMA did not detect patients at future cardiovascular risk.

    Purpose Despite the widespread use of antiemetics, nausea continues to be reported by over 70% of patients receiving chemotherapy. Methods In this double blind, multicenter trial, we randomly assigned 744 cancer patients to four arms: 1) placebo, 2) 0.5g ginger, 3) 1.0g ginger, or 4) 1.5g ginger. Nausea occurrence and severity were assessed at a baseline cycle and the two following cycles during which patients were taking their assigned study medication. All patients received a 5-HT3 receptor antagonist antiemetic on Day 1 of all cycles. Patients took three capsules of ginger (250mg) or placebo twice daily for six days starting three days before the first day of chemotherapy. Patients reported the severity of nausea on a 7-point rating scale (“1” = “Not at all Nauseated” and “7” = “Extremely Nauseated”) for Days 1-4 of each cycle. The primary outcomes were to determine the dose and efficacy of ginger at reducing the severity of chemotherapy-induced nausea on Day 1 of chemotherapy. Results A total of 576 patients were included in final analysis (91% female, mean age = 53). Mixed model analyses demonstrated that all doses of ginger significantly reduced acute nausea severity compared to placebo on Day 1 of chemotherapy (p=0.003). The largest reduction in nausea intensity occurred with 0.5g and 1.0g of ginger (p=0.017 and p=0.036, respectively). Anticipatory nausea was a key factor in acute chemotherapy-induced nausea (p<0.0001). Conclusions Ginger supplementation at daily dose of 0.5g-1.0g significantly aids in reduction of the severity of acute chemotherapy-induced nausea in adult cancer patients. PMID:21818642

    Abstract Renal dysfunction is a prevalent comorbidity in acute ischemic stroke patients requiring thrombolytic therapy. However, the effect of renal dysfunction on the clinical outcome of this population remains controversial. This study aimed to evaluate the safety and effectiveness of thrombolytic therapy in acute stroke patients with renal dysfunction using a meta-analysis. We systematically searched PubMed and EMBASE for studies that evaluated the relationship between renal dysfunction and intravenous tissue plasminogen activator (tPA) in patients with acute ischemic stroke. Poor outcome (modified Rankin Scale ≥2), mortality, and symptomatic intracranial hemorrhage (ICH) and any ICH were analyzed. Fourteen studies were included (N = 53,553 patients). The mean age ranged from 66 to 75 years. The proportion of male participants was 49% to 74%. The proportion of renal dysfunction varied from 21.9% to 83% according to different definitions. Based on 9 studies with a total of 7796 patients, the meta-analysis did not identify a significant difference in the odds of poor outcome (odds ratio [OR] = 1.06; 95% confidence interval [CI]: 0.96–1.16; I2 = 44.5) between patients with renal dysfunction and those without renal dysfunction. Patients with renal dysfunction were more likely to die after intravenous thrombolysis (OR = 1.13; 95% CI: 1.05–1.21; I2 = 70.3). No association was observed between symptomatic ICH (OR = 1.02; 95% CI: 0.94–1.10; I2 = 0) and any ICH (OR = 1.07; 95% CI: 0.96–1.18; I2 = 25.8). Renal dysfunction does not increase the risk of poor outcome and ICH after stroke thrombolysis. Renal dysfunction should not be a contraindication for administration of intravenous thrombolysis to eligible patients. PMID:25526464

    Abstract Rotation thromboelastometry (ROTEM) is a viscoelastometric point-of-care-test for the complex evaluation of changes in hemostasis, performed in whole blood. However, no prospective study evaluating the efficacy of the antiplatelet therapy using ROTEM was performed. Fifty-six patients (34 men, 22 women, mean age 67.75 years, and age range 34–88 years) with acute ST-elevation myocardial infarction (STEMI), treated with dual antiplatelet therapy, undergoing urgent coronary angiography and percutaneous coronary intervention (PCI) of culprit coronary lesion were included. Three blood samples were taken (sample 1 taken before the urgent coronary angiography, sample 2 in 24 hours after the admission, and sample 3 in 30 days after acute STEMI). Twenty-one healthy blood donors (17 men, 4 women, mean age 50.38 years, and age range 40–74 years) were recruited as the control group. Blood samples were tested with ROTEM Gamma (Pentapharm GmbH, Munich, Germany) and light transmission aggregometry (LTA). Clotting time (CT) was significantly prolonged and maximum clot firmness (MCF) was significantly higher in patients compared to controls. Mean platelet aggregation after the induction with arachidonic acid (33.2% vs 74.6% in sample 1 and 21.1% vs 74.6% in sample 2), as well as adenosine diphosphate (51.4% vs 72.7% in sample 1 and 37.1% vs 72.7% in sample 2), were significantly lower in patients with acute STEMI. Significantly prolonged CT and increased MCF was found in patients with acute STEMI. This study confirmed the ability of ROTEM to identify changes in hemostasis in ACS patients on antithrombotic therapy. PMID:28178148

    Bilateral bipolar electric carotid sinus stimulation acutely reduced muscle sympathetic nerve activity (MSNA) and blood pressure (BP) in patients with resistant arterial hypertension but is no longer available. The second-generation device uses a smaller unilateral unipolar disk electrode to reduce invasiveness while saving battery life. We hypothesized that the second-generation device acutely lowers BP and MSNA in treatment-resistant hypertensive patients. Eighteen treatment-resistant hypertensive patients (9 women/9 men; 53±11 years; 33±5 kg/m(2)) on stable medications have been included in the study. We monitored finger and brachial BP, heart rate, and MSNA. Without stimulation, BP was 165±31/91±18 mm Hg, heart rate was 75±17 bpm, and MSNA was 48±14 bursts per minute. Acute stimulation with intensities producing side effects that were tolerable in the short term elicited interindividually variable changes in systolic BP (-16.9±15.0 mm Hg; range, 0.0 to -40.8 mm Hg; P=0.002), heart rate (-3.6±3.6 bpm; P=0.004), and MSNA (-2.0±5.8 bursts per minute; P=0.375). Stimulation intensities had to be lowered in 12 patients to avoid side effects at the expense of efficacy (systolic BP, -6.3±7.0 mm Hg; range, 2.8 to -14.5 mm Hg; P=0.028 and heart rate, -1.5±2.3 bpm; P=0.078; comparison against responses with side effects). Reductions in diastolic BP and MSNA (total activity) were correlated (r(2)=0.329; P=0.025). In our patient cohort, unilateral unipolar electric baroreflex stimulation acutely lowered BP. However, side effects may limit efficacy. The approach should be tested in a controlled comparative study.

    The survival of younger patients with acute leukemia has improved in the early 21(st) century, but it is unknown whether people of all ethnic and racial backgrounds have benefited equally. Using cancer registry data from the Surveillance, Epidemiology and End Results Program, we assessed trends in 5-year relative survival for patients aged 15 years or more with acute lymphoblastic leukemia and acute myeloblastic leukemia divided by racial and ethnic group, including non-Hispanic whites, African-Americans, Hispanics, and Asian-Pacific Islanders in the 1990s and the early 21(st) century. Modeled period analysis was used to obtain the most up-to-date estimates of survival. Overall, the 5-year survival increased from 31.6% in 1997-2002 to 39.0% in 2003-2008 for patients with acute lymphoblastic leukemia and from 15.5% in 1991-1996 to 22.5% in 2003-2008 for those with acute myeloblastic leukemia. Nevertheless, among patients with acute lymphoblastic leukemia, age-adjusted 5-year relative survival rates remained lower for African-Americans and Hispanics than for non-Hispanic whites. Among patients with acute myeloblastic leukemia, the increase in survival was greatest (from 32.6% in 1991-1996 to 47.1% in 2003-2008) for younger patients (15-54 years), and was more pronounced for non-Hispanic whites (+16.4% units) than for other patients (+10.8% units). Increases in survival are observed in all ethnic or racial groups. Nevertheless, among patients with acute leukemias, disparities in survival persist between non-Hispanic white people and people of other ethnic or racial groups. Disparities are increasing in younger patients with acute myeloblastic leukemia. Improvements in access to treatment, especially for minority patients, may improve outcomes.

  1. Investigation of the degree of organisational influence on patient experience scores in acute medical admission units in all acute hospitals in England using multilevel hierarchical regression modelling

    Objectives Previous studies found that hospital and specialty have limited influence on patient experience scores, and patient level factors are more important. This could be due to heterogeneity of experience delivery across subunits within organisations. We aimed to determine whether organisation level factors have greater impact if scores for the same subspecialty microsystem are analysed in each hospital. Setting Acute medical admission units in all NHS Acute Trusts in England. Participants We analysed patient experience data from the English Adult Inpatient Survey which is administered to 850 patients annually in each acute NHS Trusts in England. We selected all 8753 patients who returned the survey and who were emergency medical admissions and stayed in their admission unit for 1–2 nights, so as to isolate the experience delivered during the acute admission process. Primary and secondary outcome measures We used multilevel logistic regression to determine the apportioned influence of host organisation and of organisation level factors (size and teaching status), and patient level factors (demographics, presence of long-term conditions and disabilities). We selected ‘being treated with respect and dignity’ and ‘pain control’ as primary outcome parameters. Other Picker Domain question scores were analysed as secondary parameters. Results The proportion of overall variance attributable at organisational level was small; 0.5% (NS) for respect and dignity, 0.4% (NS) for pain control. Long-standing conditions and consequent disabilities were associated with low scores. Other item scores also showed that most influence was from patient level factors. Conclusions When a single microsystem, the acute medical admission process, is isolated, variance in experience scores is mainly explainable by patient level factors with limited organisational level influence. This has implications for the use of generic patient experience surveys for comparison between

    Nickel was measured, by electrothermal atomic absorption spectrophotometry, in sera from (a) 30 healthy adults, (b) 54 patients with acute myocardial infarction, (c) 33 patients with unstable angina pectoris without infarction, and (d) five patients with coronary atherosclerosis who developed cardiac ischemia during treadmill exercise. Mean (and SD) concentrations in Group a were 0.3 (0.3) ..mu..g/L (range <0.05-1.1 ..mu..g/L). Within 72 h after hospital admission, hypernickelemia (Ni greater than or equal to 1.2 ..mu..g/L) was found in 41 patients of group b (76%) and in 16 patients of group c (48%). Hypernickelemia was found before and after exercise in one patient of Group d (20%). Peak values averaged 3.0 ..mu..g/L (range 0.4-21 ..mu..g/L) in Group b, 1.5 ..mu..g/L (range <0.05-3.3 ..mu..g/L) in Group c. In Group b, the mean time interval between the peak values for creatine kinase activity and for nickel was 18 h. Serum nickel concentrations were unrelated to age, sex, time of day, cigarette smoking, medications, clinical complications, or outcome. Mechanisms and sources of release of nickel into the serum of patients with acute myocardial infarction or unstable angina pectoris are conjectural, but hypernickelemia may be related to the pathogenesis of ischemic myocardial injury. 25 references, 2 figures, 6 tables.

    Platelets play a crucial role in the pathogenesis of stroke and antiplatelet agents exist for its treatment and prevention. Through the use of LC-MS based protein expression profiling, platelets from stroke patients were analyzed and then correlated with the proteomic analyses results in the context of this disease. This study was based on patients who post ischemic stroke were admitted to hospital and had venous blood drawn within 24 hrs of the incidence. Label-free protein expression analyses of the platelets’ tryptic digest was performed in triplicate on a UPLC-ESI-qTOF-MS/MS system and ProteinLynx Global Server (v2.5, Waters) was used for tandem mass data extraction. The peptide sequences were searched against the reviewed homo sapiens database (www.uniprot.org) and the quantitation of protein variation was achieved through Progenesis LC-MS software (V4.0, Nonlinear Dynamics). These Label-free differential proteomics analysis of platelets ensured that 500 proteins were identified and 83 of these proteins were found to be statistically significant. The differentially expressed proteins are involved in various processes such as inflammatory response, cellular movement, immune cell trafficking, cell-to-cell signaling and interaction, hematological system development and function and nucleic acid metabolism. The expressions of myeloperoxidase, arachidonate 12-Lipoxygenase and histidine-rich glycoprotein are involved in cellular metabolic processes, crk-like protein and ras homolog gene family member A involved in cell signaling with vitronectin, thrombospondin 1, Integrin alpha 2b, and integrin beta 3 involved in cell adhesion. Apolipoprotein H, immunoglobulin heavy constant gamma 1 and immunoglobulin heavy constant gamma 3 are involved in structural, apolipoprotein A-I, and alpha-1-microglobulin/bikunin precursor is involved in transport, complement component 3 and clusterin is involved in immunity proteins as has been discussed.

    Background The aim of this study was to evaluate changes in quality of life scores and their association with therapy and survival in unselected elderly patients with acute myeloid leukemia. Design and Methods From February 2003 to February 2007, 113 patients aged more than 60 years with de novo acute myeloid leukemia were enrolled in a prospective observational study. Two different quality of life instruments were employed: the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire – C30 (EORTC QLQ-C30) and a health-related quality of life questionnaire for patients with hematologic diseases (QOL-E). Results Forty-eight patients (42.4%) received intensive chemotherapy and 65 (57.6%) were given palliative treatments. Age greater than 70 years (P=0.007) and concomitant diseases (P=0.019) had a significant impact on treatment allocation. At diagnosis, general quality of life was affected [median QOL-E standardized score 54, interquartile range 46–70; median EORTC global score 50, interquartile range 41–66]. Most patients were given a good ECOG Performance Status (< 2), which did not correlate with the patients’ perception of quality of life. At multivariate analysis, palliative approaches (P=0.016), age more than 70 years (P=0.013) and concomitant diseases (P=0.035) each had an independent negative impact on survival. In a multivariate model corrected for age, concomitant diseases and treatment option, survival was independently predicted by QOL-E functional (P=0.002) and EORTC QLQ-C30 physical function (P=0.030) scores. Conclusions Quality of life could have an important role in elderly acute myeloid leukemia patients at diagnosis as a prognostic factor for survival and a potential factor for treatment decisions.

    We report herein the characterization of a human IgG antibody reactive with a nonmuscle 135 kD microfilament-associated protein, anti-135 kD. Using nonmuscle epithelial PtK2 cells as substrate in indirect immunofluorescence, we identified a distinctive pattern of reactivity with microfilaments in sera from 12 of 165 (7.3%) patients investigated for systemic autoimmune diseases and in only 2 of 171 (1.2%) normal and rheumatic disease controls (P < 0.006, 95% Cl 1.46 to 30.1). An association between anti-135 kD and Raynaud's phenomenon (n = 12/14, 85.7%) with or without an associated systemic autoimmune disease was noted. The anti-135 kD specificity was established by several criteria. (1) The fluorescence was periodically distributed along microfilaments and concentrated at focal adhesions for all sera (n = 14). (2) On immunoblots, the 14 sera reacted with a PtK2 polypeptide of 135 kD. (3) IgG purified by blot-affinity from the 135 kD band (alpha-135) reproduced the fluorescent pattern of the original sera while IgG purified from other bands did not. (4) Double immunofluorescence with alpha-135 and anti-alpha-actinin mAb indicated absence of antibody fluorescence at ruffling membranes where a-actinin was distributed. (5) IgG subclass analysis of anti-135 kD revealed that 12 (85.7%) sera are of IgG3 isotype and 2 (14.3%) are of IgG1 isotype while the light chain expression was kappa restricted. This is the first report of an antibody to a 135 kD microfilament protein. Anti-135 kD expand the repertoire of anti-microfilament and anticytoskeletal antibodies in human sera.

    Purpose: To determine the feasibility of and acute toxicity associated with hypofractionated whole breast radiation (HypoRT) after breast-conserving surgery in patients excluded from or underrepresented in randomized trials comparing HypoRT with conventional fractionation schedules. Methods and Materials: A review was conducted of all patients consecutively treated with HypoRT at University of Chicago. All patients were treated to 42.56 Gy in 2.66 Gy daily fractions in either the prone or supine position. Planning was performed in most cases using wedges and large segments or a 'field-in-field' technique. Breast volume was estimated using volumetric measurements of the planning target volume (PTV). Dosimetric parameters of heterogeneity (V105, V107, V110, and maximum dose) were recorded for each treatment plan. Acute toxicity was scored for each treated breast. Results: Between 2006 and 2010, 78 patients were treated to 80 breasts using HypoRT. Most women were overweight or obese (78.7%), with a median body mass index of 29.2 kg/m{sup 2}. Median breast volume was 1,351 mL. Of the 80 treated breasts, the maximum acute skin toxicity was mild erythema or hyperpigmentation in 70.0% (56/80), dry desquamation in 21.25% (17/80), and focal moist desquamation in 8.75% (7/80). Maximum acute toxicity occurred after the completion of radiation in 31.9% of patients. Separation >25 cm was not associated with increased toxicity. Breast volume was the only patient factor significantly associated with moist desquamation on multivariable analysis (p = 0.01). Patients with breast volume >2,500 mL experienced focal moist desquamation in 27.2% of cases compared with 6.34% in patients with breast volume <2,500 mL (p = 0.03). Conclusions: HypoRT is feasible and safe in patients with separation >25 cm and in patients with large breast volume when employing modern planning and positioning techniques. We recommend counseling regarding expected increases in skin toxicity in women with a PTV

    Karasu-Kalkani et al (2008 J. Math. Phys. 49 073516) recently derived a new sixth-order wave equation KdV6, which was shown by Kupershmidt (2008 Phys. Lett. 372A 2634) to have an infinite commuting hierarchy with a common infinite set of conserved densities. Incidentally, this equation was written for the first time by Calogero and is included in the book by Calogero and Degasperis (1982 Lecture Notes in Computer Science vol 144 (Amsterdam: North-Holland) p 516). In this paper, we give a geometric insight into the KdV6 equation. Using Kirillov's theory of coadjoint representation of the Virasoro algebra, we show how to obtain a large class of KdV6-type equations equivalent to the original equation. Using a semidirect product extension of the Virasoro algebra, {\\widehat{Vir \\ltimes C^{\\infty}(S^1)}} , we propose the nonholonomic deformation of the Ito equation. We also show that the Adler-Kostant-Symes scheme provides a geometrical method for constructing nonholonomic deformed integrable systems. Applying the Adler-Kostant-Symes scheme to loop algebra, we construct a new nonholonomic deformation of the coupled KdV equation.

    A novel Bacillus subtilis KD1 strain was isolated and identified from healthy broilers, and its phylogenetic classification was subsequently analyzed. To evaluate its probiotic availability, its growth characteristics and tolerance for the gut environment were evaluated in vitro. The results suggest that B. subtilis KD1 is superior in secreting neutral protease and is highly tolerant of gastric acid and bile salt. In the logarithmic growth phase, the neutral protease reached a maximum of 1,369.3 U/mL. When all live bacteria had become spores in the broth, B. subtilis KD1 was freeze dried and fed to broilers at 10(9), 5 × 10(9), and 10(10) bacilli/kg of feed. The animal trial results suggest that the addition of the new strain significantly improved intestinal flora by increasing lactobacilli and reducing Escherichia coli (P < 0.05) as compared with the control; hence, B. subtilis KD1 is a promising probiotic organism in broilers.

    Summary The clinical characteristics, treatment options and outcomes in patients with acute promyelocytic leukaemia (APL) and hyperleucocytosis remain poorly defined. This study reviewed 242 consecutive patients with APL; 29 patients (12%) had a white blood cell count (WBC) ≥ 50 × 109/l at presentation (median WBC 85.5 × 109/l). Patients with hyperleucocytosis had inferior complete remission (CR) rates (69% versus 88%; P=0.004) and higher 4-week mortality (24% versus 9%; P=0.018) compared to patients without hyperleucocytosis. We noted a trend towards inferior 3-year disease-free survival (DFS) (69% versus 80%; P=0.057) and inferior 3-year overall survival (OS) (74% versus 92%; P=0.2) for patients with hyperleucocytosis. Leukapheresis was performed in 11 (38%) of the 29 patients with hyperleucocytosis. CR rate and 3-year OS were not significantly improved in patients who received leukapheresis. CR rate and 3-year OS for the 15 patients with hyperleucocytosis treated with all-trans retinoic acid (ATRA) plus arsenic trioxide (ATO) plus cytotoxic therapy (idarubicin or gemtuzumab ozogamicin) combinations were 100% and 100% versus 57% and 35% for the 14 patients treated with non-ATRA/ATO combinations (P=0.004 and P=0.002). Leukapheresis does not improve the outcomes in patients with APL presenting with hyperleucocytosis. ATRA/ATO-based combinations are superior to other regimens in these patients. PMID:25312977

    The agents of human febrile illness can vary by region and country suggesting that diagnosis, treatment, and control programs need to be based on a methodical evaluation of area-specific etiologies. From December 2006 to December 2009, 9,997 individuals presenting with acute febrile illness at nine health care clinics in south-central Cambodia were enrolled in a study to elucidate the etiologies. Upon enrollment, respiratory specimens, whole blood, and serum were collected. Testing was performed for viral, bacterial, and parasitic pathogens. Etiologies were identified in 38.0% of patients. Influenza was the most frequent pathogen, followed by dengue, malaria, and bacterial pathogens isolated from blood culture. In addition, 3.5% of enrolled patients were infected with more than one pathogen. Our data provide the first systematic assessment of the etiologies of acute febrile illness in south-central Cambodia. Data from syndromic-based surveillance studies can help guide public health responses in developing nations.

    Neuroimmunocorrection therapy with cerebrolysin has been used for the prophylaxis of clinical pneumonia development in the early stage of acute stroke in a group of 140 patients with heavy clinical course of acute ischemic stroke (AIS). All patients in the test and control groups received the basal anti-AIS therapy and antibacterial drugs (IV-generation cephalosporins) in case of pneumonia development. The efficacy of cerebrolysin administration was evaluated both on the clinical scale (NIH-NINDS, CPIS, SIRS immonograms) and using laboratory indices. It is established that the proposed neuroimmunocorrection therapy with cerebrolysin decreases the frequency of the clinical pneumonia development. A relationship between the pneumonia onset rate and the focus localization in limbico-diencephalic part of the brain is established. The use of cerebrolysin decreases lethality, normalizes the impaired immunity indices, accelerates the restoration of violated neural functions, suppresses pneumonia development, restores the level of albumin, and normalizes the laboratory indices of inflammatory syndrome.

    A 37-year-old man, a known case of Behcet's disease with its vascular complications such as abdominal and thoracic artery aneurysms, was admitted with the diagnosis of acute anterior myocardial infarction and received thrombolytic therapy. Coronary angiography and percutaneous coronary intervention via transradial approach were performed for the patient on the eighth day of admission. The patient did not suffer from any symptoms, myocardial infarction, or readmission in the nine-month follow-up. About 25 cases of myocardial infarction associated with Behcet's disease have been reported previously. Although coronary involvement is rare in Behcet's disease, it is especially important because it affects young individuals and often presents as acute coronary syndromes.

    1993-02-05

    In a group of 19 patients with renovascular hypertension the effect of a morning snack comprising meat (1 g protein per 1 kg body weight) on urinary albumin excretion was assessed. Concurrently the plasma creatinine concentration (Pcr) was examined which varied between normal and 260 mumol/l and the creatinine clearance (Ccr). After administration of an acute protein load the mean Ccr value increased by 23%. The albumin excretion, however, did not change substantially, as compared with the previous collection period (mean 17 and 18 micrograms/min). Microalbuminuria was recorded in 31% of the patients and its prevalence was directly related to the increasing Pcr value. The results revealed that an acute protein load did not increase albuminuria although the rise of Ccr was significant. The variability of albumin excretion in the course of the day is, however, influenced also by other factors and for assessment of microalbuminuria therefore examination of 24-hour urine samples should be preferred.

    We present the joint angles analysis by means of the principal component analysis (PCA). The data from twenty-seven acute and chronic hemiplegic patients were used and compared with data from five healthy subjects. The data were collected during walking along a 10-meter long path. The PCA was applied on a data set consisting of hip, knee, and ankle joint angles of the paretic and the nonparetic leg. The results point to significant differences in joint synergies between the acute and chronic hemiplegic patients that are not revealed when applying typical methods for gait assessment (clinical scores, gait speed, and gait symmetry). The results suggest that the PCA allows classification of the origin for the deficit in the gait when compared to healthy subjects; hence, the most appropriate treatment can be applied in the rehabilitation.

    A 29-year old female presented with a one-week history of vomiting, diarrhoea, abdominal pain, and headache. On admission, she had acute renal failure requiring dialysis. Tests revealed a hemolytic anemia with thrombocytopenia. An initial diagnosis of thrombotic thrombocytopenic microangiopathy was made and plasma exchange was instigated. However, renal biopsy did not show thrombotic microangiopathy but instead revealed acute kidney injury with mild tubulointerstitial nephritis and numerous oxalate crystals, predominantly in the distal tubules. The patient had been taking large doses (>1100 mg daily) of vitamin C for many months. She also gave a history of sclerotherapy using injections of an ethylene glycol derivative for superficial leg veins. The patient completed five sessions of plasma exchange and was able to discontinue dialysis. She eventually achieved full renal recovery. She has now discontinued sclerotherapy and vitamin supplementation. PMID:21785726

    Current treatment of acute respiratory distress syndrome is based on ventilatory support with a lung protective strategy, avoiding the development of iatrogenic injury, including ventilator-induced lung injury. One of the mechanisms underlying such injury is atelectrauma, and positive end-expiratory pressure (PEEP) is advocated in order to avoid it. The indicated PEEP level has not been defined, and in many cases is based on the patient oxygen requirements for maintaining adequate oxygenation. However, this strategy does not consider the mechanics of the respiratory system, which varies in each patient and depends on many factors-including particularly the duration of acute respiratory distress syndrome. A review is therefore made of the different methods for adjusting PEEP, focusing on the benefits of individualized application.

    Spontaneous coronary artery dissection (SCAD) is a rare cause of acute myocardial infarction that is more common in younger patients (under age 50) and in women. Although the etiology is not known, some predisposing conditions to SCAD are well known and include Marfan syndrome, pregnancy and peripartum state, drug abuse, and some anatomical abnormalities of the coronary arteries such as aneurysms and severe kinking. We describe a case of SCAD in a young woman who presented with sudden onset of chest pain and was admitted for the treatment of acute coronary syndrome. The coronary angiography showed dissection of the left anterior descending artery. The patient underwent successful percutaneous transluminal coronary angioplasty and stent placement. PMID:25317268

    1991-09-01

    Although exercise ECG testing has been shown to have important prognostic value after acute myocardial infarction, exercise 201Tl scintigraphy offers several potential advantages, including: (1) increased sensitivity for detecting residual myocardial ischemia; (2) the ability to localize ischemia to a specific area or areas subtended by a specific coronary artery; (3) the ability to identify exercise-induced left ventricular dysfunction, which is manifested by increased lung uptake or transient left ventricular dilation; and (4) more reliable risk stratification of individual patients. The more optimal prognostic efficiency of 201Tl scintigraphy partially results from the fact that the error rate in falsely classifying patients as low risk is significantly smaller with 201Tl scintigraphy than with stress ECG. Because of these substantial advantages, there seems to be adequate rationale for recommending exercise perfusion imaging rather than exercise ECG alone as the preferred method for evaluating mortality and morbidity risks after acute myocardial infarction.

    The purpose of this study is to describe a single-center experience in primary coronary angioplasty in 304 consecutive patients with acute myocardial infarction. Sixty-seven percent were men and 33% women, the mean age was 69 years. The time from onset to treatment was 3.5 hours, 14% had previous bypass surgery and 23% prior myocardial infarction, 11% arrived in cardiogenic shock. Coronary angiography showed multivessel disease in 56% of patients, 73% had TIMI 0-1 flow. Successful PTCA occurred in 95% and in hospital mortality was 6.5%. Primary coronary angioplasty is a successful reperfusion method in acute myocardial infarction and it is associated with low mortality even in high risk groups. The rates of success and major complications in this series are similar to other publications.

    The role of the stroke units in improving morbidity, mortality, and recovery from stroke is clearly demonstrated. However, acute management of language disorders in these specialized units remains controversial, and management of swallowing disorders is usually nonstandardized. The recent validation of a scale for rapid screening of language disorders (LAST [Language Screening Test]) in acute stroke patients should allow optimization of their detection and early management. Swallowing disorders should be screened and managed using a standardized protocol. Following early initial evaluation repeated on a daily basis, they justify tailored rehabilitation sessions, adaptation of food textures, team formation, and families' information. The use of these protocols implies the cooperation and coordination of the medical and paramedical teams and the daily presence of speech therapists. These aspects are crucial for patients in the stroke units to achieve full benefits from the management proposed in this paper, leading to diminution of complications and better long-term functional prognosis.

    Objective In Brazil, there are few descriptions in the literature on the angiographic pattern and clinical characteristics of young patients with acute coronary syndrome, despite the evident number of cases in the population. The objective of this study was to evaluate which clinical characteristics are most closely related to the acute coronary syndrome in young patients, and what long-term outcomes are in this population. Methods This is a prospective observational study with 268 patients aged under 55 years with acute coronary syndrome, carried out between May 2010 and May 2013. Data were obtained on demographics, laboratory test and angiography results, and the coronary treatment adopted. Statistical analysis was presented as percentages and absolute values. Results Approximately 57% were men and the median age was 50 years (30 to 55). The main risk factors were arterial hypertension (68%), smoking (67%), and dyslipidemia (43%). Typical pain was present in 90% of patients. In young individuals, 25.7% showed ST segment elevation. Approximately 56.5% of patients presented with a single-vessel angiographic pattern. About 7.1% were submitted to coronary bypass surgery, and 42.1% to percutaneous coronary angioplasty. Intrahospital mortality was 1.5%, and the combined event rate (cerebrovascular accident/stroke, cardiogenic shock, reinfarction, and arrhythmias) was 13.8%. After a mean follow-up of 10 months, mortality was 9.8%, while 25.4% of the patients had new ischemic events, and 37.3% required readmission to hospital. Conclusion In the short-term, young patients presented with mortality rates below what was expected when compared to the rates noted in other studies. However, there was a significant increase in the number of events in the 10-month follow-up. PMID:26466059

    One hundred ten consecutive patients (60 males and 50 females; age, mean +/- standard deviation [SD], 22.6 +/- 6.4 years; range 16-48 years) who were clinically diagnosed with sporadic acute hepatitis between December 2004 and January 2005 in Ulaanbaatar, Mongolia, were studied. IgM antibodies to hepatitis A virus were detected in 18 patients (16.4%), IgM antibodies to hepatitis B core (anti-HBc IgM) in 38 patients (34.5%) including two patients with concurrent hepatitis delta virus (HDV) infection, and hepatitis C virus RNA in nine patients (8.2%). There were 30 hepatitis B virus (HBV) carriers who had detectable hepatitis B surface antigen and antibodies to HDV but were negative for anti-HBc IgM, suggesting that they acquired type D acute hepatitis due to superinfection of HDV on a background of chronic HBV infection. None had IgM antibodies to hepatitis E virus (HEV). Consequently, 16.4, 32.7, 6.4, 1.8, and 27.3% of the patients were diagnosed as having acute hepatitis of type A, B, C, type B + D (HBV/HDV coinfection), and type D (superinfection of HDV), respectively. The cause of hepatitis was not known in the remaining 17 patients (15.5%). All 18 HAV isolates were genotyped as IA, all 9 HCV isolates were genotyped as 1b, and all 32 HDV isolates were classified into genotype I. The distribution of HBV genotypes among the 67 HBV isolates was A (1.5%, n = 1) and D (98.5%, n = 66). The present study indicates that de novo infections of HAV, HBV, HCV, and HDV are prevalent among young adults in Mongolia.

    Swallowing dysfunction caused by stroke is a risk factor for aspiration pneumonia. Tongue pressure measurement is a simple and noninvasive method for evaluating swallowing dysfunction. We have hypothesized that low tongue pressure may be able to predict pneumonia occurrence in acute stroke patients. Tongue pressure was measured using balloon-type equipment in 220 acute stroke patients. The modified Mann Assessment of Swallowing Ability (MASA) score was evaluated independently on the same day. Tongue pressure was measured every week thereafter. An improvement in tongue pressure was observed within the first 2 weeks. Receiver operating curve analysis was performed to determine the ability of tongue pressure to predict modified MASA score <95, which suggests swallowing dysfunction. The optimal cutoff for tongue pressure was 21.6 kPa (χ2 = 45.82, p<0.001, sensitivity 95.9%, specificity 91.8%, area under the curve = 0.97). The tongue pressure was significantly lower in patients with pneumonia than in those without pneumonia. Using a Cox proportional hazard model for pneumonia onset with a cutoff tongue pressure value of 21.6 kPa and adjustment for age, sex, and National Institutes of Health Stroke Scale score at admission, the tongue pressure had additional predictive power for pneumonia onset (hazard ratio, 7.95; 95% confidence interval, 2.09 to 52.11; p = 0.0013). In the group with low tongue pressure, 27 of 95 patients showed improvement of tongue pressure within 2 weeks. Pneumonia occurred frequently in patients without improvement of tongue pressure, but not in patients with improvement (31/68 and 2/27, p<0.001). Tongue pressure is a sensitive indicator for predicting pneumonia occurrence in acute stroke patients. PMID:27802333

    Background In acute exacerbation of COPD, increased plasma levels of cardiac troponin are frequent and associated with increased mortality. Thus, we aimed at prospectively determining the diagnostic value of coronary angiography in patients with exacerbated COPD and concomitantly elevated cardiac troponin. Patients and methods A total of 88 patients (mean age 72.9±9.2 years, 56.8% male) hospitalized for acute exacerbation of COPD with elevated plasma troponin were included. All patients underwent coronary angiography within 72 hours after hospitalization. Complementary 12-lead electrocardiogram, transthoracic echocardiography, pulmonary function, and angiological testing were performed. Results Coronary angiography objectified the presence of ischemic heart disease (IHD) in 59 patients (67.0%), of whom 34 patients (38.6% of total study population) underwent percutaneous coronary intervention. Among these 34 intervened patients, the vast majority (n=26, 76.5%) had no previously known IHD, whereas only eight out of 34 patients (23.5%) presented an IHD history. Patients requiring coronary intervention showed significantly reduced left ventricular ejection fraction (45.8%±13.1% vs 55.1%±13.3%, P=0.01) and a significantly more frequent electrocardiographic ST-segment depression (20.6% vs 7.4%, P=0.01). Neither additional laboratory parameters for inflammation and myocardial injury nor lung functional measurements differed significantly between the groups. Conclusion Angiographically confirmed IHD that required revascularization occurred in 38.6% of exacerbated COPD patients with elevated cardiac troponin. In this considerable portion of patients, coronary angiography emerged to be of diagnostic and therapeutic value. PMID:27695304

    Activation of the nuclear regulatory factor NF-kappaB occurs in the lungs of patients with the acute respiratory distress syndrome (ARDS) and may contribute to the increased expression of immunoregulatory cytokines and other proinflammatory mediators in this setting. Because of the important role that NF-kappaB activation appears to play in the development of acute lung injury, we examined cytoplasmic and nuclear NF-kapppaB counterregulatory mechanisms, involving IkappaB proteins, in alveolar macrophages obtained from 7 control patients without lung injury and 11 patients with established ARDS. Cytoplasmic levels of the NF-kappaB subunits p50, p65, and c-Rel were significantly decreased in alveolar macrophages from patients with ARDS, consistent with enhanced migration of liberated NF-kappaB dimers from the cytoplasm to the nucleus. Cytoplasmic and nuclear levels of IkappaBalpha were not significantly altered in alveolar macrophages from patients with established ARDS, compared with controls. In contrast, nuclear levels of Bcl-3 were significantly decreased in patients with ARDS compared with controls (P = 0.02). No IkappaBgamma, IkappaBbeta, or p105 proteins were detected in the cytoplasm of alveolar macrophages from control patients or patients with ARDS. The presence of activated NF-kappaB in alveolar macrophages from patients with established ARDS implies the presence of an ongoing stimulus for NF-kappaB activation. In this setting, appropriate counterregulatory mechanisms to normalize nuclear levels of NF-kappaB and to suppress NF-kappaB-mediated transcription, such as increased cytoplasmic and nuclear IkappaBalpha levels or decreased Bcl-3 levels, appeared to be induced. Nevertheless, even though counterregulatory mechanisms to NF-kappaB activation are activated in lung macrophages of patients with ARDS, NF-kappaB remains activated. These results suggest that fundamental abnormalities in transcriptional mechanisms involving NF-kappaB and important in the

    Background Prediction of clinical outcome in the acute stage of ischaemic stroke can be difficult when based on patient characteristics, clinical findings and on non-contrast CT. CT perfusion and CT angiography may provide additional prognostic information and guide treatment in the early stage. We present the study protocol of the Dutch acute Stroke Trial (DUST). The DUST aims to assess the prognostic value of CT perfusion and CT angiography in predicting stroke outcome, in addition to patient characteristics and non-contrast CT. For this purpose, individualised prediction models for clinical outcome after stroke based on the best predictors from patient characteristics and CT imaging will be developed and validated. Methods/design The DUST is a prospective multi-centre cohort study in 1500 patients with suspected acute ischaemic stroke. All patients undergo non-contrast CT, CT perfusion and CT angiography within 9 hours after onset of the neurological deficits, and, if possible, follow-up imaging after 3 days. The primary outcome is a dichotomised score on the modified Rankin Scale, assessed at 90 days. A score of 0–2 represents good outcome, and a score of 3–6 represents poor outcome. Three logistic regression models will be developed, including patient characteristics and non-contrast CT (model A), with addition of CT angiography (model B), and CT perfusion parameters (model C). Model derivation will be performed in 60% of the study population, and model validation in the remaining 40% of the patients. Additional prognostic value of the models will be determined with the area under the curve (AUC) from the receiver operating characteristic (ROC) curve, calibration plots, assessment of goodness-of-fit, and likelihood ratio tests. Discussion This study will provide insight in the added prognostic value of CTP and CTA parameters in outcome prediction of acute stroke patients. The prediction models that will be developed in this study may help guide future

    Immunoblastic lymphoma developed in a patient diagnosed as having angioimmunoblastic lymphadenopathy 5 years earlier. Chemotherapy schedules including alkylating agents were administered for 1 year, resulting in subsequent remission of the lymphoma. Thirty months after the start of chemotherapy, preleukemic changes were observed in peripheral blood and bone marrow, and acute nonlymphocytic leukaemia (M5 of the FAB classification) was diagnosed shortly afterwards. The possible role of both chemotherapy and the immunodeficiency associated to angioimmunoblastic lymphadenopathy in the pathogenesis of the leukemia is discussed.

    Background Evaluation of acute chest pain in emergency department (ED), using limited resource and time, is still very difficult despite recent development of many diagnostic tools. In this study, we tried to determine the applicability of new semi-automated cardiac function analysis tool, velocity vector imaging (VVI), in the evaluation of the patients with acute chest pain in ED. Methods We prospectively enrolled 48 patients, who visited ED with acute chest pain, and store images to analyze VVI from July 2005 to July 2007. Results In 677 of 768 segments (88%), the analysis by VVI was feasible among 48 patients. Peak systolic radial velocity (Vpeak) and strain significantly decreased according to visual regional wall motion abnormality (Vpeak, 3.50 ± 1.34 cm/s for normal vs. 3.46 ± 1.52 cm/s for hypokinesia, 2.51 ± 1.26 for akinesia, p < 0.01; peak systolic radial strain -31.74 ± 9.15% fornormal, -24.33 ± 6.28% for hypokinesia, -20.30 ± 7.78% for akinesia, p < 0.01). However, the velocity vectors at the time of mitral valve opening (MVO) were directed outward in the visually normal myocardium, inward velocity vectors were revealed in the visually akinetic area (VMVO, -0.85 ± 1.65 cm/s for normal vs. 0.10 ± 1.46 cm/s for akinesia, p < 0.001). At coronary angiography, VMVO clearly increased in the ischemic area (VMVO, -0.88+1.56 cm/s for normal vs. 0.70 + 2.04 cm/s for ischemic area, p < 0.01). Conclusion Regional wall motion assessment using VVI showed could be used to detect significant ischemia in the patient with acute chest pain at ED.

    2011-10-01

    Purpose: To construct a model for the prediction of acute esophagitis in lung cancer patients receiving chemoradiotherapy by combining clinical data, treatment parameters, and genotyping profile. Patients and Methods: Data were available for 273 lung cancer patients treated with curative chemoradiotherapy. Clinical data included gender, age, World Health Organization performance score, nicotine use, diabetes, chronic disease, tumor type, tumor stage, lymph node stage, tumor location, and medical center. Treatment parameters included chemotherapy, surgery, radiotherapy technique, tumor dose, mean fractionation size, mean and maximal esophageal dose, and overall treatment time. A total of 332 genetic polymorphisms were considered in 112 candidate genes. The predicting model was achieved by lasso logistic regression for predictor selection, followed by classic logistic regression for unbiased estimation of the coefficients. Performance of the model was expressed as the area under the curve of the receiver operating characteristic and as the false-negative rate in the optimal point on the receiver operating characteristic curve. Results: A total of 110 patients (40%) developed acute esophagitis Grade {>=}2 (Common Terminology Criteria for Adverse Events v3.0). The final model contained chemotherapy treatment, lymph node stage, mean esophageal dose, gender, overall treatment time, radiotherapy technique, rs2302535 (EGFR), rs16930129 (ENG), rs1131877 (TRAF3), and rs2230528 (ITGB2). The area under the curve was 0.87, and the false-negative rate was 16%. Conclusion: Prediction of acute esophagitis can be improved by combining clinical, treatment, and genetic factors. A multicomponent prediction model for acute esophagitis with a sensitivity of 84% was constructed with two clinical parameters, four treatment parameters, and four genetic polymorphisms.

    Pulmonary embolism is a common cardiovascular emergency, but it is still often misdiagnosed due to its unspecific clinical symptoms. Elevated troponin concentrations are associated with greater morbidity and mortality in patients with pulmonary embolism. Right ventricular ischemia due to increased right ventricular afterload is believed to be underlying mechanism of elevated troponin values in acute pulmonary embolism, but a paradoxical coronary artery embolism through opened intra-artrial communication is another possible explanation as shown in our case report.

    OBJECTIVE—To develop a simple risk model as a basis for evaluating care of patients admitted with acute myocardial infarction.
METHODS—From coronary care registers, biochemistry records and hospital management systems, 2153 consecutive patients with confirmed acute myocardial infarction were identified. With 30 day all cause mortality as the end point, a multivariable logistic regression model of risk was constructed and validated in independent patient cohorts. The areas under receiver operating characteristic curves were calculated as an assessment of sensitivity and specificity. The model was reapplied to a number of commonly studied subgroups for further assessment of robustness.
RESULTS—A three variable model was developed based on age, heart rate, and systolic blood pressure on admission. This produced an individual probability of death by 30 days (P30) where P30 = 1/(1 + exp(−L30)) and L30 = −5.624 + (0.085 × age) + (0.014 × heart rate) − (0.022 × systolic blood pressure). The areas under the receiver operating characteristic curves for the reference and test cohorts were 0.79 (95% CI 0.76 to 0.82) and 0.76 (95% CI 0.72 to 0.79), respectively. To aid application of the model to routine clinical audit, a normogram relating observed mortality and sample size to the likelihood of a significant deviation from the expected 30 day mortality rate was constructed.
CONCLUSIONS—This risk model is simple, reproducible, and permits quality of care of acute myocardial infarction patients to be reliably evaluated both within and between centres.

    Introduction: Sleep is one of the basic human needs and sleep deprivation causes nu-merous adverse effects on the human body and mind. Due to reduced sleep quality in patients with acute coronary syndrome, this study was carried out to determine the effect of eye mask on sleep quality in patients with acute coronary syndrome. Methods: In this two-group controlled clinical trial, sixty patients with acute coronary syndrome in the coronary care units of Baqiyatallah Hospital in Tehran in 2010 were selected by purposeful sampling method and randomly allocated to two groups of case and control. In the case group, in the second night stay, the intervention of eye mask was done per night and by using the Petersburg's sleep quality index; sleep quality was evaluated during and at the end of hospitalization. Then data were analyzed by paired t-test, independent t-test, Spearman and Pearson's correlation coefficient and SPSS software version 19. Results: Total sleep quality score of the case group was significantly decreased after intervention (4.86 ± 1.88) from before intervention (10.46 ± 4.09) (p < 0.000). In addi-tion, total score of sleep quality after intervention in the case group (4.86 ± 1.88) was significant different from the control group (8.43 ± 1.97) (p < 0.005). Conclusion: Using eye mask, as an economical and uncomplicated method, can improve sleep quality in patients with acute coronary syndrome in the coronary care units and can be used as an alternative method of treatment instead of drug therapy.

    2016-01-01

    Pesticide formulation includes solvents (methanol and xylene) and antifreeze (ethylene glycol) whose metabolites are anions such as formic acid, hippuric acid, and oxalate. However, the effect of the anion gap on clinical outcome in acute pesticide intoxication requires clarification. In this prospective study, we compared the anion gap and other parameters between surviving versus deceased patients with acute pesticide intoxication. The following parameters were assessed in 1,058 patients with acute pesticide intoxication: blood chemistry (blood urea nitrogen, creatinine, glucose, lactic acid, liver enzymes, albumin, globulin, and urate), urinalysis (ketone bodies), arterial blood gas analysis, electrolytes (Na+, K+, Cl- HCO3-, Ca++), pesticide field of use, class, and ingestion amount, clinical outcome (death rate, length of hospital stay, length of intensive care unit stay, and seriousness of toxic symptoms), and the calculated anion gap. Among the 481 patients with a high anion gap, 52.2% had a blood pH in the physiologic range, 35.8% had metabolic acidosis, and 12.1% had acidemia. Age, anion gap, pesticide field of use, pesticide class, seriousness of symptoms (all P < 0.001), and time lag after ingestion (P = 0.048) were significant risk factors for death in univariate analyses. Among these, age, anion gap, and pesticide class were significant risk factors for death in a multiple logistic regression analysis (P < 0.001). In conclusions, high anion gap is a significant risk factor for death, regardless of the accompanying acid-base balance status in patients with acute pesticide intoxication. PMID:27366016

    In infected individuals, hepatitis C virus (HCV) exists in various forms of circulating particles which role in virus persistence and in HCV resistance to IFN therapy is still debated. Here, the proportion of HCV bound to immunoglobulin was determined in plasma of 107 chronically infected patients harbouring different HCV genotypes and, for comparison, of six patients with acute HCV infection. The results showed that, in spite of wide individual variability, chronically HCV-infected patients exhibited an extremely high proportion of immune complexed (IC) virus regardless of plasma HCV load and infecting genotype. Moreover, no significant association was found between baseline proportion of IC HCV and response to IFN treatment. Plasma samples collected within 2 weeks of treatment from 20 patients revealed a significant decline of mean IC HCV values relative to baseline that clearly paralleled the decay of total HCV load. In acutely infected patients, circulating HCV was not IC or IC at very low levels only in patients developing chronic HCV infection. Collectively, these findings strengthen the possibility that IC virus could play a critical role in the pathogenesis of HCV infection.

    Twelve episodes of acute fatty liver of pregnancy (AFLP) were diagnosed in 11 patients during the past 18 years in a general hospital in Santiago, Chile, with a prevalence of 1 per 15,900 deliveries. Acute fatty liver of pregnancy started between the 31st and 38th weeks of pregnancy, with malaise, vomiting, jaundice, and lethargy as the main clinical manifestations. Polydipsia (in nine episodes) and skin pruritus (in seven episodes) were unusual clinical findings. In two patients, pruritus started two and four weeks before AFLP, suggesting that an intrahepatic cholestasis of pregnancy preceded AFLP in those patients. Considering the current prevalence of both diseases in Chile, their association should be considered fortuitous. In another patient, two consecutive pregnancies were affected by AFLP, raising to three the number of reported patients with recurrent AFLP. In 11 episodes, liver biopsies supported the diagnosis of AFLP by showing small and midsized vacuolar cytoplasmic transformation as the most prominent histopathological feature. Positive intracellular fat staining was found in the four samples analysed. Studies by electron microscopy showed megamitochondria with paracrystalline inclusions in four samples. All the mothers survived, but fetal mortality was 58.3%. Several extrahepatic complications delayed maternal recovery for up to four weeks after delivery. This study confirms an improvement in maternal prognosis in AFLP, discusses the possibility of an epidemiological association with intrahepatic cholestasis of pregnancy, and increases the number of patients reported with recurrent AFLP.

    Acute hyperglycemia is a frequent finding in patients presenting to the emergency department (ED) with acute myocardial infarction (AMI). The prognostic role of hyperglycemia in diabetic patients with AMI remains controversial. We retrospectively reviewed patients’ medical records to obtain demographic data, clinical presentation, major adverse cardiac events (MACEs), several clinical scores and laboratory data, including the plasma glucose level at initial presentation and HbA1c levels. The glycemic gap, which represents changes in serum glucose levels during the index event, was calculated from the glucose level upon ED admission minus the HbA1c-derived average glucose (ADAG). We enrolled 331 patients after the review of medical records. An elevated glycemic gap between admission serum glucose levels and ADAG were associated with an increased risk of mortality in patients. The glycemic gap showed superior discriminative power regarding the development of MACEs when compared with the admission glucose level. The calculation of the glycemic gap may increase the discriminative powers of established clinical scoring systems in diabetic patients presenting to the ED with AMI. In conclusion, the glycemic gap could be used as an adjunct parameter to assess the severity and prognosis of diabetic patients presenting with AMI. However, the usefulness of the glycemic gap should be further explored in prospective longitudinal studies. PMID:27291987

    There are a significant number of emergency department (ED) visits for lacerations each year. When individuals experience skin, soft tissue, or laceration symptoms, the decision to go to the ED is not always easy on the basis of the level of severity. For such cases, it may be feasible to use a mobile phone camera to submit images of their wound to a remote medical provider who can review and help guide their care choice decisions. The authors aimed to assess patient attitudes toward the use of mobile phone technology for laceration management. Patients presenting to an urban ED for initial care and follow-up visits for lacerations were prospectively enrolled. A total of 194 patients were enrolled over 8 months. Enrolled patients answered a series of questions about their injury and a survey on attitudes about the acceptability of making management decisions using mobile phone images only. A majority of those surveyed agreed that it was acceptable to send a mobile phone picture to a physician for a recommendation and diagnosis. Patients also reported few concerns regarding privacy and security and believe that this technology could be cost effective and convenient. In this study, the majority of patients had favorable opinions of using mobile phones for laceration care. Mobile phone camera images (a) may provide a useful modality for assessment of some acute wound care needs and (b) may decrease ED visits for a high-volume complaint such as acute wounds.

    Purpose To measure thrombopoietin (TPO) levels in the serum and aqueous humors of patients with noninfectious acute anterior uveitis. Methods A prospective, comparative, controlled study. Serum and aqueous humors were obtained from the eyes of 16 patients with noninfectious acute anterior uveitis. TPO levels were measured using an enzyme-linked immunosorbent assay (ELISA). The results obtained were compared with those of a control group. Results Serum concentrations of TPO were not significantly different between control individuals and patients with active anterior uveitis. Aqueous humor TPO levels were 54.46±16.24 pg/mL in the eyes of patients with uveitis, and 34.32±11.63 pg/mL in the eyes of controls. The difference between the two groups was significant (Mann–Whitney U-test for independent data, P=0.0008), with uveitis patients exhibiting significantly higher levels of TPO. Conclusion The high levels of TPO in the aqueous humors of uveitis patients points toward a cytoprotective role of this factor in inflammatory repair processes and the recovery of tissue homeostasis.

    Remarkable progress has been made over the past decade in cancer medicine. Personalized medicine, driven by biomarker predictive factors, novel biotherapy, novel imaging, and molecular targeted therapeutics, has improved outcomes. Cancer is becoming a chronic disease rather than a fatal disease for many patients. However, despite this progress, there is much work to do if patients are to receive continuous high-quality care in the appropriate place, at the appropriate time, and with the right specialized expert oversight. Unfortunately, the rapid expansion of therapeutic options has also generated an ever-increasing burden of emergency care and encroaches into end-of-life palliative care. Emergency presentation is a common consequence of cancer and of cancer treatment complications. It represents an important proportion of new presentations of previously undiagnosed malignancy. In the U.K. alone, 20%–25% of new cancer diagnoses are made following an initial presentation to the hospital emergency department, with a greater proportion in patients older than 70 years. This late presentation accounts for poor survival outcomes and is often associated with poor patient experience and poorly coordinated care. The recent development of acute oncology services in the U.K. aims to improve patient safety, quality of care, and the coordination of care for all patients with cancer who require emergency access to care, irrespective of the place of care and admission route. Furthermore, prompt management coordinated by expert teams and access to protocol-driven pathways have the potential to improve patient experience and drive efficiency when services are fully established. The challenge to leaders of acute oncology services is to develop bespoke models of care, appropriate to local services, but with an opportunity for acute oncology teams to engage cancer care strategies and influence cancer care and delivery in the future. This will aid the integration of highly

    Silent infarcts (SIs) are common findings in stroke patients, but their clinical significance remains controversial. Aim of this study was to evaluate the prevalence of SI in consecutive stroke patients, characteristics, associated factors, and influence on in-hospital mortality. The population consisted of 191 patients, consecutively admitted for an acute stroke. Of 191 patients, 74 had SI on CT-scan. Silent infarcts were often multiple, right sided, lacunar. We found SI more frequently in older patients, smokers, with an ischemic stroke having small vessel disease as presumed cause. In our study SI were associated with ageing, smoke habit and lacunar stroke. Silent infarcts size influenced the rate of in-hospital mortality.

    Results of treatment of 229 patients, suffering an acute necrotic pancreatitis, complicated by peripancreatic infiltrate, were analyzed. To all the patients antibiotic prophylaxis and antibiotic therapy were conducted. In 63 (27.5%) patients the methods of extracorporal hemocorrection were applied, and in 108 (47.1%)--the "four--catheters" rule (catheter for epidural anesthesia, installment of the feeding intestinal probe further than the Treitz ligament level, the central vein catheterization, the programmed laparocentesis). In 31 (13.5%) patients there were determined the activity of mononuclear phagocytes and production of ROS (the oxygen active forms) by them in peripheral blood with objective for the purulent-septic complications prognostication. In 14 (6.1%) patients purulent--septic complications have occurred, postoperative lethality was 21.4%, general lethality--3.4%.

    Several age-associated changes in natural killer (NK) cell phenotype have been reported that contribute to the defective NK cell response observed in elderly patients. A remodelling of the NK cell compartment occurs in the elderly with a reduction in the output of immature CD56(bright) cells and an accumulation of highly differentiated CD56(dim) NK cells. Acute myeloid leukaemia (AML) is generally a disease of older adults. NK cells in AML patients show diminished expression of several activating receptors that contribute to impaired NK cell function and, in consequence, to AML blast escape from NK cell immunosurveillance. In AML patients, phenotypic changes in NK cells have been correlated with disease progression and survival. NK cell-based immunotherapy has emerged as a possibility for the treatment of AML patients. The understanding of age-associated alterations in NK cells is therefore necessary to define adequate therapeutic strategies in older AML patients.

  12. Communicating with culturally and linguistically diverse patients in an acute care setting: nurses' experiences.

    Communication with culturally and linguistically diverse (CLD) patients has been shown to be difficult. This study describes nurses' experiences of communicating with CLD patients in an acute care setting. A purposive sample of registered nurses and certified midwives (n=23) were interviewed. Main findings were: interpreters, bilingual health workers and combinations of different strategies were used to communicate with CLD patients; some nurses showed empathy, respect and a willingness to make an effort in the communication process with others showing an ethnocentric orientation. Main recommendations were: prioritising access to appropriate linguistic services, providing nurses with support from health care workers, e.g., bilingual health care workers who are able to provide more in-depth information, increasing nurses' understanding of legal issues within patient encounters, supporting nurses to translate their awareness of cultural diversity into acceptance of, appreciation for and commitment to CLD patients and their families.
