    In the acute phase of cerebral infarction, many experimental data suggest that free radicals including superoxide, hydroxy radical and nitric oxide are one of the most important factors to cause brain damage. We have clearly detected nitrotyrosine (a marker of endogenous production of peroxynitrite, which is readily produced from superoxide and nitric oxide) in neurons and intraparenchymal vascular walls during post-ischemic reperfusion. Free radical scavengers thus seem to be very promising tools of treatment, and one of them (edaravone) has recently been approved for clinical use in Japan. CREB (cyclic AMP response element binding protein) is a DNA-binding transcription factor, and its function is activated by phosphorylation of Ser133 residue. CREB plays important roles in neuronal development, synaptic plasticity and regeneration. We have found that phosphorylation of CREB is significantly and persistently increased in surviving neurons and oligodendrocytes in post-ischemic brain, while this phosphorylation is only transiently increased in neurons and oligodendrocytes which eventually die. These data suggest that CREB phosphorylation plays an important role in protection of ischemic brain tissue. Oligodendrocyte progenitor cells (OPC) remain abundant throughout the adult brain, and retain their ability to become not only mature oligodendrocytes, but also neurons. We have recently found that OPC are significantly activated and proliferate in the peri-infarct area at 1-2 weeks after ischemia, suggesting that OPC may be involved in the repair mechanisms of ischemic brain. Future targets of stroke treatment should include enhancement of intrinsic protection mechanisms such as CREB phosphorylation and activation of progenitors cells. PMID:12235793

    The true pathophysiologic nature of Peyronie's disease continues to evolve. This pathology often results in a penile plaque(s), penile deformity, curvature, pain, and erectile dysfunction. Clinically, there are two distinct phases, acute and chronic. The focus of this review will center on the management of the acute phase of Peyronie's disease. While little data exists demonstrating disease resolution, disease stabilization is an important clinical goal for patients as this often allows acceptable sexual function. Thus, medical management during the acute phase of Peyronie's disease is aimed at limiting and stabilizing the degree of penile fibrosis, decreasing penile curvature, and reducing penile pain. In this manuscript we explain different therapies; oral, topical, intralesional injection and others like extracorporeal shockwave (ESWT), radiation and penile traction for acute phase of Peyronie's disease. Although no consensus exists for the treatment of acute phase Peyronie's disease, a majority of patients can achieve stabilization and in some cases regression of their disease with proper medical therapy. The goals of therapy should be discussed extensively with each patient, noting that erectile function will be likely despite some degree of curvature.

    The acute phase of venous thromboembolism (VTE) treatment focuses on the prompt and safe initiation of full-dose anticoagulation to decrease morbidity and mortality. Immediate management consists of resuscitation, supportive care, and thrombolysis for patients with haemodynamically significant pulmonary embolism (PE) or limb-threatening deep-vein thrombosis (DVT). Patients with contraindications to anticoagulants are considered for vena cava filters. Disposition for the acute treatment of VTE is then considered based on published risk scores and the patient's social status, as the first seven days carries the highest risk for VTE recurrence, extension and bleeding due to anticoagulation. Next, a review of: immediate and long-term bleeding risk, comorbidities (i. e. active cancer, renal failure, obesity, thrombophilia), medications, patient preference, VTE location and potential for pregnancy should be undertaken. This will help determine the most suitable anticoagulant for immediate treatment. The non-vitamin K antagonist oral anticoagulants (NOACs), including the factor Xa inhibitors apixaban, edoxaban and rivaroxaban as well as the direct-thrombin inhibitor dabigatran, are increasing the convenience of and options available for VTE treatment. Current options for immediate treatment include low-molecular-weight heparin (LMWH), unfractionated heparin (UFH), fondaparinux, apixaban, or rivaroxaban. LMWH or UFH may be continued as monotherapy or transitioned to treatment with a VKA, dabigatran or edoxaban. This review describes the upfront treatment of VTE and the evolving role of NOACs in the contemporary management of VTE.

    Aortic valve injury due to blunt trauma is rare and often difficult to diagnose. Therefore, most reported cases are operated on months or years after initial injury. Reported below is the case of a 55-year-old male, who was involved in a head-on collision with a bus. He was transported to Tsukuba Medical Center by ambulance, 34 minutes after the accident. The patient presented acute shock without obvious evidence of hemorrhaging. On physical examination a murmur was detected. The murmur was evaluated by Doppler echocardiography and revealed aortic regurgitation. On further physical examination he had gross hematuria and intratracheal bleeding. Computerized tomography (CT) showed evidence of contusions to his lungs, liver, and kidneys. The individual was diagnosed with an aortic valve injury, causing aortic insufficiency. It was necessary to continuously monitor the patients' hemodynamic state, assessing when conditions to operate were most favorable. However, in the hyper-acute phase the bleeding is difficult to control. We waited for his platelet count to recover before operating on the fifth day. When the patient underwent valve repair using extracorporeal circulation (ECC), aprotinin was added to the procedure. The surgery revealed a large laceration on the right coronary cusp of the aortic valve. Repair to the valve was impossible, so replacement of the aortic valve was required. A Carbomedics mechanical valve (phi 21 mm) was inserted. The patient did well after surgery, and eventually returned to work. To date, in Japan, there are eleven such cases of aortic valve injury on file. However, this is the first reported case that involved operating during the acute phase. This case demonstrates that, with careful evaluation of coexisting injuries and control of bleeding, successful treatment of aortic valve injury using ECC is possible, even in the acute phase.

    Abstract Sudden sensorineural hearing loss (SSHL) is an otological emergency defined as a rapid hearing loss, seriously affects patient's social life. To data, no study has reported the treatment by acupuncture alone in the acute phase. In this report, Acupuncture and Moxibustion therapy of excitation-focus transfer is outlined. The patient was a 26-year-old young woman who had an SSHL coupled with ear fullness. The patient had no past medical history, but she had undergone variable emotions and had a history of excessive noise exposure. The patient refused to receive any medicine especially steroids and hyperbaric oxygen therapy. She just only received acupuncture treatment. Her symptoms and outcome measurements were improved every week and completely recovered after the last week. Even though the article presents a single case and is based on self-reports, there are very clear trends on how patients with SSHL responded to acupuncture treatments. PMID:27368045

    The acute phase of chronic periodontitis may occur even in patients during supportive periodontal therapy. However, the details are not fully understood. Since the natural environment, including meteorology affects human health, we hypothesized that weather conditions may affect occurrence of acute phase of chronic periodontitis. The aim of this study was to investigate the relationship between weather conditions and acute phase of chronic periodontitis in patients under supportive periodontal therapy. Patients who were diagnosed with acute phase of chronic periodontitis under supportive periodontal therapy during 2011–2013 were selected for this study. We performed oral examinations and collected questionnaires and meteorological data. Of 369 patients who experienced acute phase of chronic periodontitis, 153 had acute phase of chronic periodontitis without direct-triggered episodes. When using the autoregressive integrated moving average model of time-series analysis, the independent covariant of maximum hourly range of barometric pressure, maximum hourly range of temperature, and maximum daily wind speed were significantly associated with occurrence of acute phase of chronic periodontitis (p < 0.05), and 3.1% of the variations in these occurrence over the study period were explained by these factors. Meteorological variables may predict occurrence of acute phase of chronic periodontitis. PMID:26251916

    During the adulticide treatment of Dirofilaria immitis the worms die releasing fragments of parasites and causing pulmonary thromboembolisms which could exacerbate the clinical condition. To determine the utility of acute phase proteins (APPs) to monitor the progression of the treatment, different positive [C-reactive protein (CRP), haptoglobin (hp)] and negative [albumin, paraoxonase-1(PON-1)] APPs were measured in 15 heartworm-infected dogs (5 with high and 10 with low parasite burden) following adulticide treatment. The results showed increased concentrations of CRP, decreased concentrations of haptoglobin and PON-1 in infected dogs before starting the treatment. Progressive but not significant increases were observed in PON-1 activity and albumin concentration along the treatment. After the treatment with doxycycline and ivermectine a decrease in CRP and Hp levels was experienced, which could reflect a reduction of the vascular inflammation caused by the elimination of Wolbachia and reduction of microfilariae. Fifteen days after the first melarsomine injection, marked increases in CRP and Hp were observed, which could be due to pulmonary inflammation and thromboembolism caused by the post-adulticide death of the worms. This increase was greater in dogs with high parasite burden. As the pathology disappeared, there was an improvement in the concentrations of CRP and Hp, returning into reference values in dogs with low parasite burden at the end of the treatment. The measurement of CRP and Hp could be a resource of support to evaluate the magnitude of the post-adulticide complications during the adulticide treatment of D. immitis. PMID:25801227

    Acute phase response is an effector process orchestrated by the innate immune system for the optimal mobilization of the resources of the organism distant from the local insult site needed in the execution of a host-protecting reaction. Our research has shown that mice bearing tumors treated by photodynamic therapy (PDT) exhibit the three major hallmarks of acute phase response: release of acute phase reactants, neutrophilia, and pituitary/adrenal axis activation. Of particular interest in this study were acute phase proteins that have a pivotal role in the clearance of dead cells, since the occurrence of this process in PDT-treated tumors emerges as a critical event in the course of PDT-associated host response. It is shown that this type of acute phase reactants, including complement proteins (C3, C5, C9, mannose-binding lectin, and ficolin A) and related pentraxins (serum amyloid P component and PTX3), are upregulated following tumor PDT and accumulate in the targeted lesions. Based on the recently accumulated experimental evidence it is definitely established that the acute phase response is manifested in the hosts bearing PDT-treated tumors and it is becoming clear that this effector process is an important element of PDT-associated host response bearing in impact on the eventual outcome of this therapy.

  10. Treatment for sulfur mustard lung injuries; new therapeutic approaches from acute to chronic phase

    2012-01-01

    Objective Sulfur mustard (SM) is one of the major potent chemical warfare and attractive weapons for terrorists. It has caused deaths to hundreds of thousands of victims in World War I and more recently during the Iran-Iraq war (1980–1988). It has ability to develop severe acute and chronic damage to the respiratory tract, eyes and skin. Understanding the acute and chronic biologic consequences of SM exposure may be quite essential for developing efficient prophylactic/therapeutic measures. One of the systems majorly affected by SM is the respiratory tract that numerous clinical studies have detailed processes of injury, diagnosis and treatments of lung. The low mortality rate has been contributed to high prevalence of victims and high lifetime morbidity burden. However, there are no curative modalities available in such patients. In this review, we collected and discussed the related articles on the preventive and therapeutic approaches to SM-induced respiratory injury and summarized what is currently known about the management and therapeutic strategies of acute and long-term consequences of SM lung injuries. Method This review was done by reviewing all papers found by searching following key words sulfur mustard; lung; chronic; acute; COPD; treatment. Results Mustard lung has an ongoing pathological process and is active disorder even years after exposure to SM. Different drug classes have been studied, nevertheless there are no curative modalities for mustard lung. Conclusion Complementary studies on one hand regarding pharmacokinetic of drugs and molecular investigations are mandatory to obtain more effective treatments. PMID:23351279

    Polymyositis and dermatomyositis (PM/DM) are representative inflammatory muscle diseases. In treatment of PM/DM, drug therapies are cardinal but rehabilitation may be another option. Since muscles with PM/DM are fragile for muscle exercise, rehabilitation has been recommended mainly in chronic phase. Some researchers considered that rehabilitation for PM/DM patients in acute phase may improve their functional prognosis without major sideeffect. However, there are controversies about rehabilitation for PM/DM patients from acute phase. To consider advisability, I reviewed literatures concerning rehabilitation for PM/DM patients in acute phase.

    Background Recently, the application of meditative practices to the treatment of depressive disorders has met with increasing clinical and scientific interest, due to a lower side-effect burden, potential reduction of polypharmacy, as well as theoretical considerations that such interventions may target some of the cognitive roots of depression. We aimed to determine the state of the evidence supporting this application. Methods Randomized, controlled trials of techniques meeting the Agency for Healthcare Research and Quality (AHRQ) definition of meditation, for participants suffering from clinically diagnosed depressive disorders, not currently in remission, were selected. Meditation therapies were separated into praxis (i.e. how they were applied) components, and trial outcomes were reviewed. Results Eighteen studies meeting inclusionary criteria were identified, encompassing seven distinct techniques and 1173 patients, with Mindfulness-Based Cognitive Therapy comprising the largest proportion. Studies including patients suffering from acute major depressive episodes (N = 10 studies), and those with residual subacute clinical symptoms despite initial treatment (N = 8), demonstrated moderate to large reductions in depression symptoms within group, and relative to control groups. There was significant heterogeneity of techniques and trial designs. Conclusions A substantial body of evidence indicates that meditation therapies may have salutary effects on patients suffering from clinical depressive disorders during the acute and subacute phases of treatment. Due to methodological deficiences and trial heterogeneity, large-scale, randomized controlled trials with well-described comparator interventions and measures of expectation are needed to clarify the role of meditation in the depression treatment armamentarium.

    Common and pernicious adult psychiatric disorders consequent to burn injury include post-traumatic stress disorder (PTSD), major depressive disorder (MDD), and new-onset substance abuse disorder. Diagnosing and treating these disorders is complicated by the complex psychosocial issues associated with burns including grief, pain, role impairment, disfigurement, dysfunction, stigma, as well as financial and legal issues. Additionally, pre-morbid psychiatric and neurological illnesses are risk factors for burns, adding to the challenge of diagnosis and treatment. This article will focus on the diagnosis and treatment of PTSD and MDD consequent to burn trauma, as these are the major psychiatric outcomes, addressing the attendant psychosocial problems as threads in this post-trauma tapestry.

    The traditional treatment of venous thromboembolism (VTE) has been use of heparin and vitamin K antagonists (VKA), and although shown to be effective, they have numerous limitations. New oral anticoagulants (NOACs) including direct thrombin (factor IIa) inhibitors (dabigatran) and selective factor Xa inhibitors (rivaroxaban, apixaban and edoxaban) have emerged as promising alternatives with the potential to overcome the limitations of traditional treatments. Clinical trials have been performed with a view to making significant changes to the acute, long-term and extended treatment of VTE. Data are now available on the efficacy and safety, including bleeding rates, of the NOACs in comparison with VKA in the acute treatment and secondary prevention of VTE as well as in comparison with placebo extended VTE treatment. This review compares and contrasts the design and results of the Phase III trials of NOACs in VTE and discusses the implications of the NOACs in terms of treatment strategies in VTE patients.

    We aimed to characterize a large international cohort of outpatients with MDD within a practical trial design, in order to identify clinically useful predictors of outcomes with three common antidepressant medications in acute-phase treatment of major depressive disorder (MDD). The international Study to Predict Optimized Treatment in Depression has presently enrolled 1008 treatment-seeking outpatients (18-65 years old) at 17 sites (five countries). At pre-treatment, we characterized participants by symptoms, clinical history, functional status and comorbidity. Participants were randomized to receive escitalopram, sertraline or venlafaxine-extended release and managed by their physician following usual treatment practices. Symptoms, function, quality of life, and side-effect outcomes were assessed 8 weeks later. The relationship of anxiety to response and remission was assessed by comorbid Axis I diagnosis, presence/absence of anxiety symptoms, and dimensionally by anxiety symptom severity. The sample had moderate-to-severe symptoms, but substantial comorbidity and functional impairment. Of completers at week 8, 62.2% responded and 45.4% reached remission on the 17-item Hamilton Rating Scale for Depression; 53.3% and 37.6%, respectively on the 16-item Quick Inventory of Depressive Symptoms. Functional improvements were seen across all domains. Most participants had side effects that occurred with a frequency of 25% or less and were reported as being in the "none" to minimal/mild range for intensity and burden. Outcomes did not differ across medication groups. More severe anxiety symptoms at pre-treatment were associated with lower remission rates across all medications, independent of depressive severity, diagnostic comorbidity or side effects. Across medications, we found consistent and similar improvements in symptoms and function, and a dimensional prognostic effect of comorbid anxiety symptoms. These equivalent outcomes across treatments lay the foundation for

    We report the results of a phase I study with four dose levels of bortezomib in combination with idarubicin. Eligible patients were newly diagnosed with acute myeloid leukemia (AML) age ≥60 years, or any adult with relapsed AML. Bortezomib was given twice weekly at 0.8, 1.0, or 1.2 mg/m(2) with once weekly idarubicin 10 mg/m(2) for four weeks. Twenty patients were treated: 13 newly diagnosed (median age 68, range 61-83) and 7 relapsed (median age 58, range 40-77). Prior myelodysplastic syndrome (MDS) was documented in 10/13 (77%) newly diagnosed and 1/7 (14%) relapsed patients; the three newly diagnosed patients without prior MDS had dyspoietic morphology. Two dose-limiting toxicities occurred at the initial dose level (bortezomib 0.8 mg/m(2) and idarubicin 10 mg/m(2)); idarubicin was reduced to 8 mg/m(2) without observing subsequent dose-limiting toxicities. The maximum tolerated dose in this study was bortezomib 1.2 mg/m(2) and idarubicin 8 mg/m(2). Common adverse events included: neutropenic fever, infections, constitutional symptoms, and gastrointestinal symptoms. No subjects experienced neurotoxicity. Most patients demonstrated hematologic response as evidenced by decreased circulating blasts. Four patients (20%) achieved complete remission. There was one treatment-related death. The combination of bortezomib and idarubicin in this mostly poor-risk, older AML group was well tolerated and did not result in high mortality. This trial was registered at www.clinicaltrials.gov as #NCT00382954.

    A woman had been followed since 1957 for acute phase Chagas disease. Parasitological and serological tests were positive, and treatment included benznidazole in 1974. Following treatment, parasitological test results were negative and conventional serology remained positive until 1994, with subsequent discordant results (1995-1997). The results became consistently negative since 1999. She had an indeterminate chronic form until 1974. Only two minor and transitory nonspecific alterations on electrocardiogram were noted, with the last nine records normal until June 2014. This case confirms the possibility of curing chronic disease and suggests the benefit of specific treatments for preventing long-term morbidity. PMID:26516979

    The objective of this study was to evaluate the efficacy, safety and tolerability of brexpiprazole versus placebo in adults with acute schizophrenia. This was a 6-week, multicenter, placebo-controlled double-blind phase 3 study. Patients with acute schizophrenia were randomized to brexpiprazole 1, 2 or 4 mg, or placebo (2:3:3:3) once daily. The primary endpoint was changed from baseline at week 6 in Positive and Negative Syndrome Scale (PANSS) total score; the key secondary endpoint was Clinical Global Impressions-Severity (CGI-S) at week 6. Brexpiprazole 4 mg showed statistically significant improvement versus placebo (treatment difference: -6.47, p=0.0022) for the primary endpoint. Improvement compared with placebo was also seen for the key secondary endpoint (treatment difference: -0.38, p=0.0015), and on multiple secondary efficacy outcomes. Brexpiprazole 1 and 2mg also showed numerical improvements versus placebo, although p>0.05. The most common treatment-emergent adverse events were headache, insomnia and agitation; incidences of akathisia were lower in the brexpiprazole treatment groups (4.2%-6.5%) versus placebo (7.1%). Brexpiprazole treatment was associated with moderate weight gain at week 6 (1.23-1.89 kg versus 0.35 kg for placebo); there were no clinically relevant changes in laboratory parameters and vital signs. In conclusion, brexpiprazole 4 mg is an efficacious and well-tolerated treatment for acute schizophrenia in adults. Clinical Trials.gov NCT01393613; BEACON trial.

    In recent years, combinations of pharmacological treatments have become common for the treatment of bipolar disorder type I (BP I); however, this practice is usually not evidence-based and rarely considers monotherapy drug regimen (MDR) as an option in the treatment of acute phases of BP I. Therefore, we evaluated comparative data of commonly prescribed MDRs for both manic and depressive phases of BP I. Medline, PsycINFO, EMBASE, the Cochrane Library, the ClinicalStudyResults.org and other data sources were searched from 1949 to March 2009 for placebo and active controlled randomized clinical trials (RCTs). Risk ratios (RRs) for response, remission, and discontinuation rates due to adverse events (AEs), lack of efficacy, or discontinuation due to any cause, and the number needed to treat or harm (NNT or NNH) were calculated for each medication individually and for all evaluable trials combined. The authors included 31 RCTs in the analyses comparing a MDR with placebo or with active treatment for acute mania, and 9 RCTs comparing a MDR with placebo or with active treatment for bipolar depression. According to the collected evidence, most of the MDRs when compared to placebo showed significant response and remission rates in acute mania. In the case of bipolar depression only quetiapine and, to a lesser extent, olanzapine showed efficacy as MDR. Overall, MDRs were well tolerated with low discontinuation rates due to any cause or AE, although AE profiles differed among treatments. We concluded that most MDRs were efficacious and safe in the treatment of manic episodes, but very few MDRs have demonstrated being efficacious for bipolar depressive episodes. PMID:20128953

    Eighty percent of all cases of acute pancreatitis are linked etiologically to gallstone disease or caused by immoderate alcohol consumption. No specific causal treatment for acute pancreatitis exists. Early prognostic factors that indicate severe disease are three or more signs on organ failure scores according to Ranson, Imrie, or Acute Physiology and Chronic Health Evaluation (APACHE) 11, extrapancreatic complications of the disease, or the detection of pancreatic necrosis on CT scans. Elevated CRP levels above 130 mg/L can also predict a severe course of acute pancreatitis. The essential medical treatment for acute pancreatitis is the correction of hypovolemia. Moreover, relief of often severe visceral pain is a high priority. Prophylactic antibiotics should be restricted to patients with necrotizing pancreatitis, infected necrosis, or other infectious complications. Enteral nutrition has no adverse effect compared with parenteral nutrition during the course of acute pancreatitis, and is probably beneficial in regard to outcome.

    Abstract Efficacy and security of a plasmapheresis procedure in complex of treatment of nonbiliary acute pancreatitis in early phase of the disease were established, basing on the treatment results analysis in 48 patients. The plasmapheresis results were estimated in accordance to changes revealed in the intoxication leukocytic index (ILI), a general protein (GP) content, general calcium (GC) in the blood plasm and of the activated partial thrombin time (APTHT). Application of plasmapheresis in patients, suffering purulent pancreatitis in the enzymal phase, have guaranteed a staged reduction of ILI by (34.86 ± 1.27)%, the APTHT enhancement from (35.15 ± 0.37) to (52.01 ± 0.62) sec, a trustworthy lowering of the GP by (4.35 ± 0.02) g/L at average and of GC in a blood plasmby (10.45 ± 0.38)%.

    An acute-phase response (APR), manifested as an increase of acute-phase proteins has been shown in major depression. Panic disorder (PD) may share some aetiopathogenic mechanisms with depression, but APR has not been studied in this disorder. Forty-one panic patients in the first stages of their illness were compared with 32 healthy subjects of comparable sex, age, and body mass index. Clinical diagnosis was established with the mini international neuropsychiatric interview, and severity with the panic disorder severity scale and the CGI scale. Laboratory determinations included four acute phase proteins (APPs) [albumin, gammaglobulins, fibrinogen, C-reactive-protein (CRP)] and basal cortisol level. Patients were studied after 8-wk follow-up taking selective serotonin reuptake inhibitors (SSRIs) to assess the evolution of the APPs. Gammaglobulin levels were lower, and both cortisol and CRP levels were higher in PD patients than in controls. APP did not differ between patients with or without agoraphobia. At follow-up, patients who responded to SSRIs presented a decrease in albumin levels, and a trend towards a decrease in cortisol and CRP compared with levels at intake. The conclusions of this study are that there is an APR in patients suffering from PD, and this APR tends to diminish after a successful treatment with SSRIs. PMID:15927091

    Efficacy of conventional opioids can be limited by adverse events (AEs). TRV130 is a structurally novel biased ligand of the μ-opioid receptor that activates G protein signaling with little β-arrestin recruitment. In this phase 2, randomized, placebo- and active-controlled study, we investigated the efficacy and tolerability of TRV130 in acute pain after bunionectomy. We used an adaptive study design in which 144 patients experiencing moderate-to-severe acute pain after bunionectomy were randomized to receive double-blind TRV130, placebo, or morphine in a pilot phase. After pilot phase analysis, 195 patients were randomized to receive double-dummy TRV130 0.5, 1, 2, or 3 mg every 3 hours (q3h); placebo; or morphine 4 mg q4h intravenously. The primary end point was the time-weighted average change in numeric rating scale pain intensity over the 48-hour treatment period. Secondary end points included stopwatch and categorical assessments of pain relief. Safety and tolerability were also assessed. TRV130 2 and 3 mg q3h, and morphine 4 mg q4h produced statistically greater mean reductions in pain intensity than placebo over 48 hours (P < 0.005). TRV130 at 2 and 3 mg produced significantly greater categorical pain relief than morphine (P < 0.005) after the first dose, with meaningful pain relief occurring in under 5 minutes. TRV130 produced no serious AEs, with tolerability similar to morphine. These results demonstrate that TRV130 rapidly produces profound analgesia in moderate-to-severe acute pain, suggesting that G-protein-biased μ-opioid receptor activation is a promising target for development of novel analgesics.

    There are many options for acute migraine attack treatment, but none is ideal for all patients. This study aims to review current medical office-based acute migraine therapy in adults and provides readers with an organized approach to this important facet of migraine treatment. A general literature review includes a review of several recent published guidelines. Acetaminophen, 4 nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, acetylsalicylic acid [ASA], naproxen sodium, and diclofenac potassium), and 7 triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, and zolmitriptan) have good evidence for efficacy and form the core of acute migraine treatment. NSAID-triptan combinations, dihydroergotamine, non-opioid combination analgesics (acetaminophen, ASA, and caffeine), and several anti-emetics (metoclopramide, domperidone, and prochlorperazine) are additional evidence-based options. Opioid containing combination analgesics may be helpful in specific patients, but should not be used routinely. Clinical features to be considered when choosing an acute migraine medication include usual headache intensity, usual rapidity of pain intensity increase, nausea, vomiting, degree of disability, patient response to previously used medications, history of headache recurrence with previous attacks, and the presence of contraindications to specific acute medications. Available acute medications can be organized into 4 treatment strategies, including a strategy for attacks of mild to moderate severity (strategy one: acetaminophen and/or NSAIDs), a triptan strategy for patients with severe attacks and for attacks not responding to strategy one, a refractory attack strategy, and a strategy for patients with contraindications to vasoconstricting drugs. Acute treatment of migraine attacks during pregnancy, lactation, and for patients with chronic migraine is also discussed. In chronic migraine, it is particularly important that medication

    Patients with acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS) not fit for intensive treatment need novel therapy options. Vascular endothelial growth factor (VEGF) receptor inhibition is one potential mechanism by which AML and MDS could be treated. The receptor tyrosine kinase inhibitor AZD2171 (cediranib) has activity against VEGF receptors KDR and FLT-1. This multicenter phase II study was designed to test cediranib's activity in patients with AML or high-risk MDS. The primary endpoint was confirmed disease response defined as a composite of complete remission, partial remission or hematologic improvement. The study enrolled 23 subjects in the AML cohort and 16 subjects in the MDS cohort. There were no confirmed responses in either group. Since the study met the stopping rule after the first stage of enrollment, the trial was closed to further accrual. Common adverse events in both cohorts included thrombocytopenia, neutropenia, anemia, fatigue, dyspnea, diarrhea, nausea and dehydration. PMID:25329007

    2010-04-01

    Optimum acute treatment of migraine requires prevention of headache as a top priority. Recognition of the multitude of migraine presentations, the frequency of total headache attacks, and number of days of headache disability are critical. Successful treatment requires excellent patient-clinician communication enhancing confidence and mutual trust based on patient needs and preferences. Optimum management of acute migraine nearly always requires pharmacologic treatment for rapid resolution. Migraine-specific triptans, dihydroergotamine, and several antiinflammatories have substantial empirical clinical efficacy. Older nonspecific drugs, particularly butalbital and opioids, contribute to medication overuse headache and are to be avoided. Clinicians should utilize evidence-based acute migraine-specific therapy stressing the imperative acute treatment goal of early intervention, but not too often with the correct drug, formulation, and dose. This therapy needs to provide cost-effective fast results, meaningful to the patient while minimizing the need for additional drugs. Migraine-ACT evaluates 2-hour pain freedom with return to normal function, comfort with treatment, and consistency of response. Employ a thoroughly educated patient, formulary, testimonials, stratification, and rational cotherapy against the race to central sensitization for optimum outcomes. PMID:20352584

    Background. The global emergence of carbapenem-resistant Enterobacteriaceae highlights the urgent need to reduce carbapenem dependence. The phase 3 RECAPTURE program compared the efficacy and safety of ceftazidime-avibactam and doripenem in patients with complicated urinary tract infection (cUTI), including acute pyelonephritis. Methods. Hospitalized adults with suspected or microbiologically confirmed cUTI/acute pyelonephritis were randomized 1:1 to ceftazidime-avibactam 2000 mg/500 mg every 8 hours or doripenem 500 mg every 8 hours (doses adjusted for renal function), with possible oral antibiotic switch after ≥5 days (total treatment duration up to 10 days or 14 days for patients with bacteremia). Results. Of 1033 randomized patients, 393 and 417 treated with ceftazidime-avibactam and doripenem, respectively, were eligible for the primary efficacy analyses; 19.6% had ceftazidime-nonsusceptible baseline pathogens. Noninferiority of ceftazidime-avibactam vs doripenem was demonstrated for the US Food and Drug Administration co-primary endpoints of (1) patient-reported symptomatic resolution at day 5: 276 of 393 (70.2%) vs 276 of 417 (66.2%) patients (difference, 4.0% [95% confidence interval {CI}, −2.39% to 10.42%]); and (2) combined symptomatic resolution/microbiological eradication at test of cure (TOC): 280 of 393 (71.2%) vs 269 of 417 (64.5%) patients (difference, 6.7% [95% CI, .30% to 13.12%]). Microbiological eradication at TOC (European Medicines Agency primary endpoint) occurred in 304 of 393 (77.4%) ceftazidime-avibactam vs 296 of 417 (71.0%) doripenem patients (difference, 6.4% [95% CI, .33% to 12.36%]), demonstrating superiority at the 5% significance level. Both treatments showed similar efficacy against ceftazidime-nonsusceptible pathogens. Ceftazidime-avibactam had a safety profile consistent with that of ceftazidime alone. Conclusions. Ceftazidime-avibactam was highly effective for the empiric treatment of cUTI (including acute

    We present our experience with 21 patients of pemphigus vulgaris seen over a period of 10 years managed in service hospitals during acute phase of the disease. Age groups of patients ranged from 25-45 years. Eighteen (85.7%) were young adults, 30-40 years of age. Fifteen (71.4%) were men and 6 (28.6%) were women. All the cases were hospitalized in ICU, till the acute phase of the disease subsided. Complete hematological profile, urinalysis, serum biochemistry and repeated bacterial cultures from the skin were carried out in all patients at the time of admission and thereafter weekly. The treatment comprised of potassium permanganate lotion bath (1:10,000) and 1 framycetin gauze dressing of the denuded areas, maintenance of fluid and electrolyte balance. All suspected infections and septicemia were treated with appropriate antibiotics. The corticosteroids were usually administered as a single dose of prednisolone 1 mg/kg/day. Cyclophosphamide was given at an initial dose of 50 mg/day and the dose was escalated to 100 mg/day. Once the bulk of the lesions were healed, the dose of corticosteroids was gradually lowered by approximately 50% every two weeks and cyclophosphamide was continued till patients were symptom-free. Out of 21 patients receiving corticosteroids, cyclophosphamide and other supportive therapy, 20 (95%) had undergone clinical resolution of the disease. During follow up study 15 (71.4%) patients remained symptom-free and undergone clinical remission. Five patients (23.8%) had relapse, out of which 4 (19%) remained symptom free, after subsequent treatment. There was one death (4.7%) in our study.

    Experimental inflammation in rats led to a sevenfold increase in serum levels of alpha 1 acute-phase globulin. This increase is correlated with elevated levels of translatable mRNA for alpha 1 acute-phase globulin in the liver. Biosynthesis and secretion of alpha 1 acute-phase globulin were studied in rat hepatocyte primary cultures. An intracellular form of alpha 1 acute-phase globulin with an apparent relative molecular mass of 63 500 and a secreted form of 68 000 were found. The intracellular form of alpha 1 acute-phase globulin could be deglycosylated by endoglucosaminidase H treatment indicating that its oligosaccharide chains were of the high-mannose type. The secreted form of alpha 1 acute-phase globulin was not sensitive to endoglucosaminidase H, but was susceptible to the action of sialidase reflecting carbohydrate side-chains of the complex type. Pulse-chase experiments revealed a precursor-product relationship for the high-mannose and the complex type alpha 1 acute-phase globulin. In the hepatocyte medium newly synthesized alpha 1 acute-phase globulin was detected 30 min after the pulse. Unglycosylated alpha 1 acute-phase globulin was found in the cells as well as in the medium when the transfer of oligosaccharide chains onto the polypeptide chains was blocked by tunicamycin. Tunicamycin led to a marked delay in alpha 1 acute-phase globulin secretion. PMID:2578391

    Acute radiation dermatitis is a common side-effect of radiotherapy which often necessitates interruption of the therapy. Currently, there is no general consensus about its prevention or about the treatment of choice. The goal of this work was to focus on optimal methods to prevent and manage acute skin reactions related to radiation therapy and to determine if there are specific topical or oral agents for the prevention of this acute skin reaction. The prevention and the early treatment are the two focus points of the management of the acute radiation dermatitis.

    There is currently lack of information on the changes of acute phase proteins (APP) and antioxidant markers and their clinical relevance as treatment response indicators in canine monocytic ehrlichiosis (CME). The objective of this study was to investigate the patterns of C-reactive protein (CRP), haptoglobin (Hp), ferritin and paraoxonase-1 (PON-1) during treatment of dogs with acute CME with rifampicin. Blood serum samples from ten Beagle dogs with experimental acute CME were retrospectively examined. Five dogs (Group A) were treated with rifampicin (10mg/Kg/24h), per os, for 3 weeks and 5 dogs (Group B) received no treatment (infected controls). Two Beagle dogs served as uninfected controls. Blood serum samples were serially examined prior to Ehrlichia canis inoculation and on post-inoculation days 14, 21, 28, 35 and 42. Significant changes of CRP, Hp, ferritin and PON-1 values were found in the majority of infected dogs. However, their concentrations did not differ between the two groups during the treatment observation period. The results of this study indicate that although several APP and PON-1 tend to significantly change in the majority of dogs with acute CME, they were of limited clinical relevance as treatment response indicators in this experimental setting.

  1. Acute Phase Proteins and Their Role in Periodontitis: A Review

    PubMed Central

    2015-01-01

    Acute phase proteins are a class of proteins whose plasma concentration increase (positive acute phase proteins) or decrease (negative acute phase proteins) in response to inflammation. This response is called as the acute phase reaction, also called as acute phase response, which occurs approximately 90 minutes after the onset of a systemic inflammatory reaction. In Periodontitis endotoxins released from gram negative organisms present in the sub gingival plaque samples interact with Toll- like receptors (TLR) that are expressed on the surface of Polymorphonuclear leucocytes (PMNs) and monocytes which are in abundance in periodontal inflammation. The complex formed due to interaction of Endotoxins and TLR activates the Signal transduction pathway in both innate and adaptive immunity resulting in production of Cytokines that co- ordinate the local and systemic inflammatory response. The pro inflammatory cytokines originating at the diseased site activates the liver cells to produce acute phase proteins as a part of non specific response. The production of Acute phase proteins is regulated to a great extent by Cytokines such as IL-1, IL-6, IL-8, TNF-α and to a lesser extent by Glucocorticoid hormones. These proteins bind to bacteria leading to activation of complement proteins that destroys pathogenic organisms. Studies have shown that levels of acute phase proteins are increased in otherwise healthy adults with poor periodontal status. This article highlights about the synthesis, structure, types and function of acute phase proteins and the associated relation of acute phase proteins in Periodontitis. PMID:26674303

    Recurrent acute pancreatitis (RAP) is a challenging condition that can lead to chronic pancreatitis and long-term morbidity. Etiology-based treatment can potentially have an impact on the natural history of RAP and its progression to chronic pancreatitis. In cases of divisum-associated RAP and idiopathic RAP, several studies have been performed to evaluate the efficacy of endoscopic therapy in alleviation of symptoms and frequency of AP events. This review discusses the literature available on these topic as well as touching on the role of endoscopic therapy in smoldering acute pancreatitis.

    Neuromyelitis optica (NMO) is a severe inflammatory demyelinating disease with exacerbations involving recurrent or bilateral optic neuritis and longitudinally extensive transverse myelitis. Pulse steroid therapy is recommended as the initial, acute-phase treatment for NMO. If ineffective, treatment with plasma exchange (PE) should commence. However, no evidence exists to support the effectiveness of PE long after the acute phase. Immunoadsorption therapy (IA) eliminates pathogenic antibodies while sparing other plasma proteins. With IA, side effects of PE resulting from protein substitution can be avoided. However, whether IA is effective for NMO remains unclear. We describe a patient with anti-aquaporin-4-positive myelitis who responded to IA using a tryptophan polyvinyl alcohol gel column that was begun 52 days after disease onset following the acute phase. Even long after the acute phase when symptoms appear to be stable, IA may be effective and should not be excluded as a treatment choice.

    Vincristine is a component of acute lymphoblastic leukemia (ALL) treatment with the potential to induce peripheral neuropathy. Recently, the CEP72 rs924607 TT genotype was found to be associated with vincristine-induced toxicity during the continuation phase in pediatric ALL patients treated on the Total XIIIB and COG AALL0433 protocols at St Jude Children's Research Hospital and Children's Oncology Group. This finding could provide a base for safer dosing of vincristine. Nevertheless, there are variations in vincristine regimens among ALL treatment protocols and phases in different populations. Therefore, the aim of this study was to determine whether the CEP72 rs924607 TT genotype is a useful marker of vincristine neuropathy during induction therapy among Spanish children with B-ALL treated on the LAL-SHOP protocols. No association was found between neurotoxicity during the induction phase and the rs924607 TT genotype. This lack of association could be because of population differences and/or differences in neurotoxicity etiology between induction and continuation phases of treatment. PMID:26618658

    The association of vitamin C deficiency with nutritional factors is commonly recognized. However, an acute form of scurvy can occur in patients with an acute systemic inflammatory response, which is produced by sepsis, medications, cancer or acute inflammation. The frequency of acute hypovitaminosis C in hospitalized patients is higher than previously recognized. We report the occurrence of acute signs and symptoms of scurvy (perifollicular petechiae, erythema, gingivitis and bleeding) in a patient hospitalized for treatment of metastatic renal-cell carcinoma with high-dose interleukin-2. Concomitantly, serum vitamin C levels decreased to below normal. Better diets and longer lifespan may result a lower frequency of acute scurvy and a higher frequency of scurvy associated with systemic inflammatory responses. Therefore, increased awareness of this condition can lead to early recognition of the cutaneous signs of acute scurvy in hospitalized patients with acute illnesses or in receipt of biological agents, and prevent subsequent morbidity such as bleeding, anaemia, impaired immune defences, oedema or neurological symptoms.

    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. PMID:26189890

    In the immediate period after traumatic spinal cord injury (SCI) a variety of secondary injury mechanisms combine to gradually expand the initial lesion size, potentially leading to diminished neurological outcomes at long-term follow-up. Riluzole, a benzothiazole drug, which has neuroprotective properties based on sodium channel blockade and mitigation of glutamatergic toxicity, is currently an approved drug that attenuates the extent of neuronal degeneration in patients with amyotrophic lateral sclerosis. Moreover, several preclinical SCI studies have associated riluzole administration with improved functional outcomes and increased neural tissue preservation. Based on these findings, riluzole has attracted considerable interest as a potential neuroprotective drug for the treatment of SCI. Currently, a Phase I trial evaluating the safety and pharmacokinetic profile of riluzole in human SCI patients is being conducted by the North American Clinical Trials Network (NACTN) for Treatment of Spinal Cord Injury. The current review summarizes the existing preclinical and clinical literature on riluzole, provides a detailed description of the Phase I trial, and suggests potential opportunities for future investigation.

    Human Natural Killer (NK) cells require at least two signals to trigger tumor cell lysis. Absence of ligands providing either signal 1 or 2 provides NK resistance. We manufactured a lysate of a tumour cell line which provides signal 1 to resting NK cells without signal 2. The tumor-primed NK cells (TpNK) lyse NK resistant Acute Myeloid Leukemia (AML) blasts expressing signal 2 ligands. We conducted a clinical trial to determine the toxicity of TpNK cell infusions from haploidentical donors. 15 patients with high risk AML were screened, 13 enrolled and 7 patients treated. The remaining 6 either failed to respond to re-induction chemotherapy or the donor refused to undergo peripheral blood apheresis. The conditioning consisted of fludarabine and total body irradiation. This was the first UK trial of a cell therapy regulated as a medicine. The complexity of Good Clinical Practice compliance was underestimated and led to failures requiring retrospective independent data review. The lessons learned are an important aspect of this report. There was no evidence of infusional toxicity. Profound myelosuppression was seen in the majority (median neutrophil recovery day 55). At six months follow-up, three patients treated in Complete Remission (CR) remained in remission, one patient infused in Partial Remission had achieved CR1, two had relapsed and one had died. One year post-treatment one patient remained in CR. Four patients remained in CR after treatment for longer than their most recent previous CR. During the 2 year follow-up six of seven patients died; median overall survival was 400 days post infusion (range 141–910). This is the first clinical trial of an NK therapy in the absence of IL-2 or other cytokine support. The HLA-mismatched NK cells survived and expanded in vivo without on-going host immunosuppression and appeared to exert an anti-leukemia effect in 4/7 patients treated.

    An acute myocardial infarction, is an infrequent complication in pregnant women. We present the case of a 29-years-old patient who suffered 2 acute myocardial infarction in relation with her two pregnancies. The first acute myocardial infarction occurred the third day after delivery, and the second, during the seventh month of the second pregnancy. In the latter, delivery was vaginal, with epidural anaesthesia. A coronary angiogram showed coronary arteries without significant narrowings, as well as an aneurysm of the left ventricle. A review of the literature published so far is made in the discussion.

    Background In animal models of ischaemic stroke, 25% albumin reduced brain infarction and improved neurobehavioral outcome. In a pilot clinical trial, albumin doses as high as 2 g per kg were safely tolerated. Trial Design and Methods This was a randomised, parallel-group, double-blind trial to test the superiority of 25% albumin (dose 2 g [8 ml] per kg; maximum, 750 ml) over an equivalent volume of isotonic saline in improving the outcome of acute ischaemic stroke. Eligibility criteria were an ischaemic (i.e., non-haemorrhagic) stroke with baseline National Institutes of Health Stroke Scale (NIHSS) score of 6 or above, ability to treat within 5 hours of onset, age 18 through 83 years, and written informed consent. The major exclusion criteria were cardiovascular. The objective was to test the hypothesis that the primary outcome (defined as either a modified Rankin Scale score of 0 or 1, or a NIHSS score of 0 or 1, or both, at 90 days) with albumin treatment was superior to saline by an absolute margin of 10 percentage points. Centralised web-based randomisation was by a minimisation-plus-biased-coin algorithm. Thrombolytic therapies were permitted. The trial is registered with ClinicalTrials.gov, Identifier: NCT00235495. Findings The trial was stopped prematurely for futility after 841 participants were randomised (422 patients to albumin and 419 to saline). The primary outcome did not differ by treatment assignment (albumin, 44.1%; saline, 44.2%; relative benefit, 0.96; 95% confidence interval [CI] 0.84 – 1.10 adjusted for baseline NIHSS score and thrombolysis stratum). Secondary outcomes were also neutral. The chief adverse event was mild-to-moderate pulmonary edema, which was more common with albumin than saline (13.1% and 1.2%, respectively), as was symptomatic intracranial haemorrhage within 24 hours (albumin, 4.1%; saline, 1.7%). While the favourable outcome rate in albumin-treated subjects remained consistent at 44–45% over the course of the trial, the

    Symptoms of alcohol withdrawal range in severity from mild "hangover" to fatal delirium tremens (DTs). Tremor, hallucinosis, and seizures usually occur within 48 hours of abstinence. Seizures tend to be generalized without focality, occurring singly or in a brief cluster, but status epilepticus is not unusual. DTs usually appears after 48 hours of abstinence and consists of marked inattentiveness, agitation, hallucinations, fluctuating level of alertness, marked tremulousness, and sympathetic overactivity. The mainstay of treatment for alcohol withdrawal is benzodiazepine pharmacotherapy, which can be used to control mild early symptoms, to prevent progression to DTs, or to treat DTs itself. Alternative less evidence-based pharmacotherapies include phenobarbital, anticonvulsants, baclofen, gamma-hydroxybutyric acid, beta-blockers, alpha-2-agonists, and N-methyl-d-aspartate receptor blockers. Treatment of DTs is a medical emergency requiring heavy sedation in an intensive care unit, with close attention to autonomic instability, fever, fluid loss, and electrolyte imbalance. Frequent comorbid disorders include hypoglycemia, liver failure, pancreatitis, sepsis, meningitis, intracranial hemorrhage, and Wernicke-Korsakoff syndrome.

  17. Microbiology and Treatment of Acute Apical Abscesses

    PubMed Central

    Rôças, Isabela N.

    2013-01-01

    SUMMARY Acute apical abscess is the most common form of dental abscess and is caused by infection of the root canal of the tooth. It is usually localized intraorally, but in some cases the apical abscess may spread and result in severe complications or even mortality. The reasons why dental root canal infections can become symptomatic and evolve to severe spreading and sometimes life-threatening abscesses remain elusive. Studies using culture and advanced molecular microbiology methods for microbial identification in apical abscesses have demonstrated a multispecies community conspicuously dominated by anaerobic bacteria. Species/phylotypes commonly found in these infections belong to the genera Fusobacterium, Parvimonas, Prevotella, Porphyromonas, Dialister, Streptococcus, and Treponema. Advances in DNA sequencing technologies and computational biology have substantially enhanced the knowledge of the microbiota associated with acute apical abscesses and shed some light on the etiopathogeny of this disease. Species richness and abundance and the resulting network of interactions among community members may affect the collective pathogenicity and contribute to the development of acute infections. Disease modifiers, including transient or permanent host-related factors, may also influence the development and severity of acute abscesses. This review focuses on the current evidence about the etiology and treatment of acute apical abscesses and how the process is influenced by host-related factors and proposes future directions in research, diagnosis, and therapeutic approaches to deal with this disease.

    Human bartonellosis is a South American anthroponosis caused by Bartonella bacilliformis. The disease has an acute phase characterized by invasion of red blood cells by parasites, and consequent severe anemia; and a chronic phase presenting with benign vascular tumors. During the acute phase, affected individuals are prone to developing opportunistic infections with a variety of organisms similar to the ones seen in AIDS. After antibiotic treatment is instituted, a subgroup of patients may develop atypical symptoms which potentially represent clinical manifestations of the restoration of macrophage function. We speculate that the pathophysiology of the acute phase of human bartonellosis resembles AIDS, with a period of immunosuppression following the infection and later, clinical manifestations of immune reconstitution subsequent to treatment.

    Use of gestation stalls in pork production remains a controversial topic in animal welfare. Immune status and measures are frequently used to assess stress levels and thus well-being of confined animals. The important welfare issue of close confinement among gestating gilts was tested by quantifying cortisol, acute phase cytokine, and acute phase protein pro-files before and after farrowing of gilts housed in 2 systems. Landrace x Yorkshire crossbred gilts housed in groups of 4 (group, n = 8) in pens (3.9 x 2.4 m with 4 individual feeding spaces, 9.36 m(2) total or 2.34 m(2)/gilt) were compared with gilts housed in standard industry stalls (stall, n = 16; 2.2 x 0.6 m, 1.32 m(2)/gilt). Floors were fully slatted, and a substrate was not provided for either system. Cortisol was determined from saliva on d 105 of gestation, 1 h after moving the gilts into farrowing stalls (d 111), and 24 h and 7 d after farrowing. Cortisol was greater (P = 0.04) for group gilts compared with stall gilts 1 h after moving them into farrowing stalls and 24 h after farrowing. Cortisol concentrations decreased (P = 0.001) over time. Leukocyte mRNA expression of IL-1, IL-1 receptor antagonist, and tumor necrosis factor-alpha was determined by quantitative, reverse transcription PCR on d 35, 63, and 91 of gestation and 72 h after farrowing. Cytokine mRNA expression of peripheral blood mononuclear cells did not differ between housing systems for IL-1, its receptor antagonist, or for tumor necrosis factor-alpha. Acute phase proteins, including fibrinogen, haptoglobin, and alpha(1)-acid glycoprotein were determined for plasma samples taken at d 35, 63, and 91 of gestation and 72 h and 14 d after farrowing. In contrast to cortisol, plasma fibrinogen concentrations increased (P < 0.005) over time. Haptoglobin did not differ between treatments (P > 0.10). Stall gilts tended to have greater (P = 0.07) plasma alpha(1)-acid glycoprotein concentrations than group animals at d 35 of gestation and d 14

    Background The infectivity of the HIV-1 acute phase has been directly measured only once, from a retrospectively identified cohort of serodiscordant heterosexual couples in Rakai, Uganda. Analyses of this cohort underlie the widespread view that the acute phase is highly infectious, even more so than would be predicted from its elevated viral load, and that transmission occurring shortly after infection may therefore compromise interventions that rely on diagnosis and treatment, such as antiretroviral treatment as prevention (TasP). Here, we re-estimate the duration and relative infectivity of the acute phase, while accounting for several possible sources of bias in published estimates, including the retrospective cohort exclusion criteria and unmeasured heterogeneity in risk. Methods and Findings We estimated acute phase infectivity using two approaches. First, we combined viral load trajectories and viral load-infectivity relationships to estimate infectivity trajectories over the course of infection, under the assumption that elevated acute phase infectivity is caused by elevated viral load alone. Second, we estimated the relative hazard of transmission during the acute phase versus the chronic phase (RHacute) and the acute phase duration (dacute) by fitting a couples transmission model to the Rakai retrospective cohort using approximate Bayesian computation. Our model fit the data well and accounted for characteristics overlooked by previous analyses, including individual heterogeneity in infectiousness and susceptibility and the retrospective cohort's exclusion of couples that were recorded as serodiscordant only once before being censored by loss to follow-up, couple dissolution, or study termination. Finally, we replicated two highly cited analyses of the Rakai data on simulated data to identify biases underlying the discrepancies between previous estimates and our own. From the Rakai data, we estimated RHacute = 5.3 (95% credibility interval [95% CrI]: 0

    Prognosis of elderly patients with acute myeloid leukemia (AML) remains poor and new treatment approaches are urgently needed. A novel nucleoside analog sapacitabine has recently emerged as a feasible agent because of its oral administration and acceptable toxicity profile. Clinical efficacy of sapacitabine, both as a single agent and in combination, has been evaluated in elderly AML patients or AML patients unfit for standard intensive chemotherapy. Response rates varied from 15 to 45% in phase II studies. Sapacitabine was overall well-tolerated with gastrointestinal and myelosuppression-related complications were the most common side effects. Unfortunately, in a phase III study sapacitabine showed no clinical superiority as compared to low-dose cytarabine (LDAC) in patients with AML. Another large phase III study comparing the combination of sapacitabine with decitabine to decitabine alone is currently ongoing and is expected to be completed by the end of 2015 or by the first half of 2016.

    Diagnosis and treatment results of 57 patients with acute diffuse brain injury have been analyzed. Patients were divided into two groups: first study period 2000-2005; second study period 2006-2010. The main differences between the first and the second study periods were in health condition and brain functions monitoring parameters, therapy approaches and goals. Increasing of axial and lateral dislocation symptoms during progression from the first type of diffuse injury to the fourth one is related to intracranial hypertension (ICH) occurrence rate and significance it's significance. During the second study period, ICH was found in 25% patients with the second type of injury, 57% patients with the third type of injury, and 80%, with the fourth type of injury. Mean ICP in the group of patients with the second type of diffuse injury comprised 14.4 +/- 6.6 mmHg; with the third type of injury, 30 +/- 20.6 mmHg; with the fourth type of injuty, 37.6 +/- 14.1 mmHg. Introduction of differentiated approach to conservative or surgical treatment method application to acute diffuse brain injuries patients based on ICP monitoring data led to 13.8% reduction in mortality in the second study period compared with the first study period.

    JNJ-Q2 is a fluoroquinolone with broad coverage including methicillin-resistant Staphylococcus aureus (MRSA). A double-blind, multicenter, phase II noninferiority study treated 161 patients for 7 to 14 days, testing the efficacy of JNJ-Q2 (250 mg, twice a day [BID]) versus linezolid (600 mg, BID) in patients with acute bacterial skin and skin structure infections (ABSSSI). The prespecified criterion for noninferiority was 15%. Primary intent-to-treat analysis was unable to declare noninferiority, as the risk difference lower bound of the 95% confidence interval between treatments was 19% at 36 to 84 h postrandomization for the composite end point of lesion assessment and temperature. Prespecified clinical cure rates 2 to 14 days after completion of therapy were similar (83.1% for JNJ-Q2 versus 82.1% for linezolid). Post hoc analyses revealed that JNJ-Q2 was statistically noninferior to linezolid (61.4% versus 57.7%, respectively; P = 0.024) based on the 2010 FDA guidance, which defines treatment success as lack of lesion spread and afebrile status within 48 to 72 h postrandomization. Despite evidence of systemic disease, <5% of patients presented with fever, suggesting fever is not a compelling surrogate measure of systemic disease resolution for this indication. Nausea and vomiting were the most common adverse events. Of the patients, 86% (104/121) had S. aureus isolated from the infection site; 63% of these were MRSA. The results suggest JNJ-Q2 shows promise as an effective treatment for ABSSSI, demonstrating (i) efficacy for early clinical response (i.e., lack of spread of lesions and absence of fever at 48 to 72 h), and (ii) cure rates for ABSSSI pathogens (especially MRSA) consistent with the historical literature.

    This article focuses on the pathogenesis, clinical manifestations, and various treatment modalities for acute hyperkalemia and presents a systematic approach to selecting a treatment strategy. Hyperkalemia, a life-threatening condition caused by extracellular potassium shift or decreased renal potassium excretion, usually presents with non-specific symptoms. Early recognition of moderate to severe hyperkalemia is vital in preventing fatal cardiac arrhythmias and muscle paralysis. Management of hyperkalemia includes the elimination of reversible causes (diet, medications), rapidly acting therapies that shift potassium into cells and block the cardiac membrane effects of hyperkalemia, and measures to facilitate removal of potassium from the body (saline diuresis, oral binding resins, and hemodialysis). Hyperkalemia with potassium level more than 6.5 mEq/L or EKG changes is a medical emergency and should be treated accordingly. Treatment should be started with calcium gluconate to stabilize cardiomyocyte membranes, followed by insulin injection, and b-agonists administration. Hemodialysis remains the most reliable method to remove potassium from the body and should be used in cases refractory to medical treatment. Prompt detection and proper treatment are crucial in preventing lethal outcomes. PMID:23882341

    Treatment for acute hepatitis C virus (HCV) infection has significantly better outcomes than treatment for chronic infection. The short window of the acute period poses challenges for young injection drug users (IDU), who are at highest risk of HCV infection, to demonstrate treatment candidacy. We recruited patients with acute HCV from a prospective cohort study to examine clinical and behavioral issues related to treatment candidacy. We report on outcomes and how nursing case management affected candidacy. All five acutely-infected participants reported daily drug use at baseline. All established primary care and decreased their drug use. None received treatment for their acute infection; one was treated within 12 months of infection. Establishing treatment candidacy for young IDU in the acute phase involves various health domains. An acute infection's short period poses many challenges to establishing candidacy, but it is a window of opportunity to engage young IDU in health care. PMID:21497111

    Migraine is a common disabling primary headache disorder. Despite the need for a perfect treatment of this debilitating condition, the ideal “cure” eludes us. In 1992, the first triptan was released in the US for use in acute migraine. Triptans are more specific for the serotonin receptor 5-hydroxy triptamine (5-HT) 1 than previously prescribed drugs, such as ergotamines, with fewer side effects. This was an important first step in specific acute migraine therapy. Today however, triptans continue to be underutilized. There remains a concern, among practitioners and patients, about possible cardiovascular safety issues, despite the lack of strong evidence of serious adverse events. In fact, triptans now have a safe track record over more than a decade of use. Other perceived downfalls to use, include cost and variable efficacy. The more we learn about the clinical features and pathophysiology of migraine, the closer we are to finding a satisfactory monotherapy. Until then, recognizing that mixed mechanisms underlie migraine symptoms, rational polytherapy can be useful. Research on the roles of serotonin, calcitonin gene related peptide, glutamine and N-methyl-D-aspartate in the trigeminovascular system holds promise for those searching for the perfect migraine headache cure.

    Berlin-Frankfurt-Munster (BFM) and Dana-Farber Cancer Institute (DFCI) consortia's treatment strategies for acute lymphoblastic leukaemia (ALL) in children are widely used. We compared the health effects and monetary costs of hospital treatments for these two strategies. Parents of children treated at seven centres in Canada, Italy and the USA completed health-related quality of life (HRQL) assessments during four active treatment phases and at 2 years after treatment. Mean HRQL scores were used to calculate quality-adjusted life years (QALYs) for a period of 5 years following diagnosis. Total costs of treatment were determined from variables in administrative databases in a universally accessible and publicly funded healthcare system. Valid HRQL assessments (n = 1200) were collected for 307 BFM and 317 DFCI patients, with costs measured for 66 BFM and 28 DFCI patients. QALYs per patient were <1.0% greater for BFM than DFCI. Median HRQL scores revealed no difference in QALYs. The difference in mean total costs for BFM (US$88 480) and DFCI (US$93 026) was not significant (P = 0.600). This study provides no evidence of superiority for one treatment strategy over the other. Current BFM or DFCI strategies should represent conventional management for the next economic evaluation of treatments for ALL in childhood. PMID:24393150

    The use of triptans has improved the ability to treat migraine successfully compared with older treatments. Speed of relief, consistency of effect, and good tolerability have been the hallmarks of these agents. All of the currently available triptans have comparable efficacy and tolerability. Variables between the agents may lead to one agent or dose form being preferred over another in various clinical scenarios. The triptans that are forthcoming may improve on these options through enhanced efficacy rates, tolerability, and headache recurrence rates. There exist increasing options for migraine treatment that may further improve the clinical effects of the older and newer triptans through early treatment of migraine at the stages of mild migraine pain, or even during the prodromal phase of the attack. Additionally, recent work suggests that mini-prophylaxis of migraine at the menses is a highly successful treatment option with the triptans. In this age of managed care, providing cost-effective treatment of headache will take on increasing importance. Techniques such as stratification of acute treatments may enhance cost-effective care, whereas ready availability of the triptans may lead to significant improvements in utilization of parameters such as office visits, emergency room treatment, and even hospitalization.

    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.

  16. Endovascular treatment of acute ischemic stroke.

    Endovascular thrombectomy is an effective treatment for major acute ischemic stroke syndromes caused by major anterior circulation artery occlusions (commonly referred to as large vessel occlusion) and is superior to intravenous thrombolysis and medical management. Treatment should occur as quickly as is reasonably possible. All patients with moderate to severe symptoms (National Institutes of Health stroke scale >8) and a treatable occlusion should be considered. The use of neuroimaging is critical to exclude hemorrhage and large ischemic cores. Very shortly after stroke onset (<3 hours) computed tomography (CT) and CT angiography provide sufficient information to proceed; diffusion magnetic resonance imaging (MRI) is less reliable during this early stage. After 3 hours from onset diffusion MRI is the most reliable method to define ischemic core size and should be used in centers that can offer it rapidly. Recanalization is highly effective with a stentriever or using a direct aspiration technique, with the patient awake or under conscious sedation rather than general anesthesia, if it may be performed safely. After thrombectomy the patient should be admitted to an intensive care setting and inpatient rehabilitation undertaken as soon as feasible. Patient outcomes should be assessed at 3 months, preferably using the modified Rankin score. PMID:27430469

    Injuries to the acromioclavicular joint occur commonly in athletes, especially those involved in contact sports. The majority of these injuries are type I and II acromioclavicular joint separations and are treated nonoperatively with rehabilitation. A rapid and full return to play is expected. Acute types IV, V, and VI are less common and operative intervention is recommended. The type III injury is more controversial and current trends are towards initial nonoperative management. Operative treatment is sought only when the athlete remains symptomatic with painful instability. However, some do support early intervention in the overhead athlete. The goal of operative intervention is to create a stiff and strong repair/reconstruction of the coracoclavicular ligaments while providing stability in all planes. This will allow early and more aggressive rehabilitation. Surgical treatment includes reconstruction of the coracoclavicular ligaments with an augmented coracoacromial ligament transfer and more recently tendon graft reconstructions. Biomechanical research supports an anatomic reconstruction of the ligaments to confer the most function and stability.

    Acute pancreatitis (AP) has a fast onset and progression, which lead to an unfavorable prognosis. Therefore, the development of novel drugs for its treatment is critical. As a homologous derivative of resveratrol, pterostilbene exerts a variety of effects including anti-inflammatory, antioxidant, and antitumor effects. This study investigated the potential of pterostilbene for treatment of severe AP (SAP) and related mechanisms. Effects of pterostilbene were evaluated in a Wistar rat model of AP. Serum levels of amylase (AMY), creatinine (Cr), and alanine aminotransferase (ALT) were quantified. Furthermore, serum levels of tumor necrosis factor (TNF)-a and interleukin (IL)-1b were quantified using enzyme-linked immunosorbent assay. Nuclear factor (NF)-kB expression in pancreatic tissues was quantified by real-time PCR and western blotting. The production of reactive oxygen species (ROS) was determined using a spectrometer, while superoxide dismutase (SOD) activity was assayed. In the AP rat model, the expression of inflammatory markers TNF-a and IL-1b, expression of NF-kB, and serum indices (AMY, Cr, and ALT) increased compared to the corresponding levels in the control group (P < 0.05). Pterostilbene reduced serum levels of TNF-a and IL-1b; decreased NF-kB gene expression, serum indices, and ROS generation; and increased SOD activity in a dose-dependent manner. In conclusion, pterostilbene can alleviate SAP-induced tissue damage by decreasing the inflammatory response and by promoting antioxidation leading to the protection of pancreatic tissues.

    After patients with major depressive disorder (MDD) respond to acute-phase cognitive therapy (CT), continuation-phase treatments may be applied to improve long-term outcomes. We clarified which CT responders experience remission, recovery, relapse, and recurrence by testing baseline demographic, clinical, and personality variables. The sample of CT responders at higher risk of relapse (N = 241) was randomized to 8 months of continuation-phase CT, double-blinded fluoxetine, or pill placebo, and followed 24 months (Jarrett & Thase, 2010). Patients with lower positive emotionality and behavioral activation at the end of acute-phase CT showed increased risk for relapse/recurrence of MDD. In addition, patients with lower positive emotionality and behavioral activation, as well as higher residual depression (including emotional, cognitive, and social facets), showed decreased probability of remission (≥6 continuous weeks of minimal or absent symptoms) after acute-phase CT. Finally, patients with greater residual depression, as well as younger age and earlier MDD onset, showed decreased probability of recovery (≥35 continuous weeks of minimal or absent symptoms) after acute-phase CT. Moderator analyses did not reveal differential prediction across the continuation phase treatment arms. These results may help clinicians gauge the prognoses and need for continuation treatment among MDD patients who respond to acute-phase CT.

    We evaluated the acute phase protein response in capybaras (Hydrochoerus hydrochaeris). Three animal groups were used: 1) healthy animals (n=30), 2) a group in which experimental inflammation with turpentine was induced (n=6), and 3) a group affected with sarcoptic scabies (n=14) in which 10 animals were treated with ivermectin. Haptoglobin (Hp), acid-soluble glycoprotein (ASG) and albumin were analyzed in all animals. In those treated with turpentine, Hp reached its maximum value at 2 wk with a 2.7-fold increase, whereas ASG increased 1.75-fold and albumin decreased 0.87-fold 1 wk after the induction of inflammation. Capybaras affected with sarcoptic scabies presented increases in Hp and ASG of 4.98- and 3.18-fold, respectively, and a 0.87-fold decrease in albumin, compared with healthy animals. Haptoglobin and ASG can be considered as moderate, positive acute phase proteins in capybaras because they showed less than 10-fold increases after an inflammatory process and reached their peak concentrations 1 wk after the induction of inflammation. Conversely, albumin can be considered a negative acute phase protein in capybaras because it showed a reduction in concentration after inflammatory stimulus.

    Background and Purpose We report a novel finding of caloric conversion from normal responses into unilateral paresis during the acute phase of vestibular neuritis (VN). Methods We recruited 893 patients with a diagnosis of VN at Dizziness Clinic of Seoul National University Bundang Hospital from 2003 to 2014 after excluding 28 patients with isolated inferior divisional VN (n=14) and those without follow-up tests despite normal caloric responses initially (n=14). We retrospectively analyzed the neurotological findings in four (0.5%) of the patients who showed a conversion from initially normal caloric responses into unilateral paresis during the acute phase. Results In those four patients, the initial caloric tests were performed within 2 days of symptom onset, and conversion into unilateral caloric paresis was documented 1–4 days later. The clinical and laboratory findings during the initial evaluation were consistent with VN in all four patients except for normal findings in bedside head impulse tests in one of them. Conclusions Normal findings in caloric tests should be interpreted with caution during the acute phase of suspected VN. Follow-up evaluation should be considered when the findings of the initial caloric test are normal, but VN remains the most plausible diagnosis. PMID:26932259

    Chemotherapy remains the first-choice option for adjuvant therapy in breast cancer. Here, we investigated the impact of the first chemotherapic cycle of doxorubicin on the plasmatic-proteomic profiling of women diagnosed with breast cancer (n = 87). Blood samples were obtained from the same patient before and after doxorubicin infusion (1 h, 60 mg/m(2)) and processed for label-free LC-MS proteomic screening. A total of 80 proteins were downregulated after chemotherapy. In silico analysis revealed that the main biological process enrolled was inflammation and canonical pathways involving acute phase proteins. TNF-α, IL-1β, IL-12, TGF-β1, clusterin, and gelsolin were chosen as relevant for further validation. All selected targets presented reduced plasmatic levels after treatment. Our results indicate that doxorubicin downregulated acute phase proteins immediately after its infusion. Since such proteins are cancer promoting, its downregulation could support the effectiveness of doxorubicin along treatment.

    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.

    To investigate the in vivo acute phase molecular response of the brain to ionizing radiation, C3Hf/Sed/Kam mice were given midbrain or whole-body irradiation. Cerebral expression of interleukins (IL-1{alpha}, IL-1{beta}, IL-2, IL-3, IL-4, IL-5, IL-6), interferon (IFN-{gamma}), tumor necrosis factors (TNF-{alpha} and TNF-{beta}), intercellular adhesion molecule-1 (ICAM-1), inducible nitric oxide synthetase (iNOS), von Willebrand factor (vWF), {alpha}1-antichymotrypsin (EB22/5.3), and glial fibrillary acidic protein (GFAP) was measured at various times after various radiation doses by ribonuclease (RNase) protection assay. The effects of dexamethasone or pentoxifylline treatment of mice on radiation-induced gene expression were also examined. Levels of TNF-{alpha}, IL-1{beta}, ICAM-1, EB22/5.3, and to a lesser extent IL-1{alpha} and GFAP, messenger RNA were increased in the brain after irradiation, whether the dose was delivered to the whole body or only to the midbrain. Responses were radiation dose dependent, but were not found below 7 Gy; the exception being ICAM-1, which was increased by doses as low as 2 Gy. Most responses were rapid, peaking within 4-8 h, but antichymotrypsin and GFAP responses were delayed and still elevated at 24 h, by which time the others had subsided. Pretreatment of mice with dexamethasone or pentoxifylline suppressed radiation-induced gene expression, either partially or completely. Dexamethasone was more inhibitory than pentoxifylline at the doses chosen. The initial response of the brain to irradiation involves expression of inflammatory gene products, which are probably responsible for clinically observed early symptoms of brain radiotherapy. This mechanism explains the beneficial effects of the clinical use of steroids in such circumstances. 64 refs., 4 figs.

    The half-lives of typical acute phase proteins in rats and beagle dogs during acute inflammation were investigated. Acute inflammation was induced by injection of turpentine oil in rats and administration of indomethacin in beagle dogs. Serum concentrations of α2-macroglobulin (α2M) and C-reactive protein (CRP) were measured by enzyme-linked immunosorbent assay and α1-acid glycoprotein (AAG) was measured by single radial immunodiffusion. Half-life was calculated as 0.693/elimination rate constant (K). The mean half-lives in the terminal elimination phase of α2M and AAG were 68.1 and 164.8 h, respectively. The half-life of AAG was significantly longer than that of α2M. Mean half-lives in the terminal elimination phase of CRP and AAG were 161.9 and 304.4 h, respectively. The half-life of AAG was significantly longer than that of CRP in beagle dogs. No significant differences in the half-life of AAG were observed between rats and beagle dogs. Furthermore, serum concentrations in the terminal elimination phase could be simulated with the K data acquired in this study.

    The Paliperidone ER Treatment in Acute Intervention (PERTAIN) study was designed to explore treatment response, tolerability, and safety of flexible doses of paliperidone ER in patients with schizophrenia admitted for an acute exacerbation. This paper addresses a secondary analysis of PERTAIN data designed to explore predictors for treatment response, flexible dosing, and concomitant benzodiazepine use. This prospective, multicenter, phase 3b, open-label, single-arm, 6-week study used flexible doses of paliperidone ER (3 to 12mg once daily) to treat patients hospitalized for an acute exacerbation of schizophrenia, reflecting more closely daily clinical practice. Predictive models were evaluated for paliperidone ER flexible dosing, treatment response, and concomitant treatment with benzodiazepines as distinct independent variables. For the analysis of explanatory variables, a stepwise logistic regression was used, taking into account patient age, gender, body mass index, diagnosis and duration of schizophrenia, number of prior hospitalizations, psychotic symptoms (PANSS), disease severity (CGI-S), and patient functioning (PSP) at baseline. Early response (defined as response within 2weeks of treatment initiation) was also used as a predictor. Clinical response (defined as ≥30% decrease in PANSS total score and ≥1 point decrease in CGI-S from baseline to endpoint) was predicted by early clinical response (p<0.001) and there was a trend for the diagnosis of paranoid schizophrenia vs. other types of schizophrenia to predict clinical response (p=0.0525). High response (defined as ≥50% decrease in PANSS total score and ≥2 points decrease in CGI-S from baseline to endpoint) was predicted by early high response, higher baseline CGI-S, or female gender. More severely ill patients with a higher baseline CGI-S were twice likely to be treated concomitantly with a benzodiazepine. PMID:24096139

    Background Alcohol abuse is associated with impaired circadian rhythms and sleep. Ethanol administration disrupts circadian clock phase-resetting, suggesting a mode for the disruptive effect of alcohol abuse on the circadian timing system. In this study, we extend previous work in C57BL/6J mice to: 1) characterize the SCN pharmacokinetics of acute systemic ethanol administration; 2) explore the effects of acute ethanol on photic and non-photic phase-resetting; and 2) determine if the SCN is a direct target for photic effects. Methods First, microdialysis was used to characterize the pharmacokinetics of acute i.p. injections of 3 doses of ethanol (0.5, 1.0 and 2.0 g/kg) in the mouse suprachiasmatic (SCN) circadian clock. Second, the effects of acute i.p. ethanol administration on photic phase-delays and serotonergic ([+]8-OH-DPAT-induced) phase-advances of the circadian activity rhythm were assessed. Third, the effects of reverse-microdialysis ethanol perfusion of the SCN on photic phase-resetting were characterized. Results Peak ethanol levels from the 3 doses of ethanol in the SCN occurred within 20–40 min post-injection with half-lives for clearance ranging from 0.6–1.8 hr. Systemic ethanol treatment dose-dependently attenuated photic and serotonergic phase-resetting. This treatment also did not affect basal SCN neuronal activity as assessed by Fos expression. Intra-SCN perfusion with ethanol markedly reduced photic phase-delays. Conclusions These results confirm that acute ethanol attenuates photic phase-delay shifts and serotonergic phase-advance shifts in the mouse. This dual effect could disrupt photic and non-photic entrainment mechanisms governing circadian clock timing. It is also significant that the SCN clock is a direct target for disruptive effects of ethanol on photic shifting. Such actions by ethanol could underlie the disruptive effects of alcohol abuse on behavioral, physiological, and endocrine rhythms associated with alcoholism. PMID:21463340

    Acute pancreatitis (AP) is a potentially life-threatening disease with a wide spectrum of severity. The overall mortality of AP is approximately 5%. According to the revised Atlanta classification system, AP can be classified as mild, moderate, or severe. Severe AP often takes a clinical course with two phases, an early and a late phase, which should both be considered separately. In this review article, we first discuss general aspects of AP, including incidence, pathophysiology, etiology, and grading of severity, then focus on the assessment of patients with suspected AP, including diagnosis and risk stratification, followed by the management of AP during the early phase, with special emphasis on fluid therapy, pain management, nutrition, and antibiotic prophylaxis.

    Alcohol abuse is associated with sleep problems, which are often linked to circadian rhythm disturbances. However, there is no information on the direct effects of ethanol on the mammalian circadian clock. Acute ethanol inhibits glutamate signaling, which is the primary mechanism through which light resets the mammalian clock in the suprachiasmatic nucleus (SCN). Glutamate and light also inhibit circadian clock resetting induced by non-photic signals, including serotonin. Thus, we investigated the effects of acute ethanol on both glutamatergic and serotoninergic resetting of the SCN clock in vitro. We show that ethanol dose-dependently inhibits glutamate-induced phase shifts and enhances serotonergic phase shifts. The inhibition of glutamate-induced phase shifts is not affected by excess glutamate, glycine or D-serine, but is prevented by excess brain-derived neurotrophic factor (BDNF). BDNF is known to augment glutamate signaling in the SCN and to be necessary for glutamate/light-induced phase shifts. Thus, ethanol may inhibit glutamate-induced clock resetting at least in part by blocking BDNF enhancement of glutamate signaling. Ethanol enhancement of serotonergic phase shifts is mimicked by treatments that suppress glutamate signaling in the SCN, including antagonists of glutamate receptors, BDNF signaling and nitric oxide synthase. The combined effect of ethanol with these treatments is not additive, suggesting they act through a common pathway. Our data indicate further that the interaction between serotonin and glutamate in the SCN may occur downstream from nitric oxide synthase activation. Thus, acute ethanol disrupts normal circadian clock phase regulation, which could contribute to the physiological and psychological problems associated with alcohol abuse. PMID:18313227

    2014-01-01

    The perceived advantages of endovascular treatment for acute ischemic stroke in terms of recanalization, the multimodal and targeted approaches, and perhaps the more permissive rules on devices than on medications for their licensing favored the assumption that endovascular treatment is superior to intravenous thrombolysis for acute treatment of ischemic stroke, and its adoption in more advanced stroke centers. However, this assumption has been questioned by recent clinical trial experience showing that endovascular treatment is not superior to intravenous thrombolysis. The new evidence has changed the perception and the importance of conducting randomized trials in this area. This summary examines the background and outcomes of the latest experience with endovascular techniques in acute stroke treatment based on historical data. The new challenge is how to study the latest generation of devices called stent retrievers, which are faster in recanalizing and easier to use, in selected patients with acute ischemic stroke. In the meantime, the available evidence does not provide support for the use of endovascular treatment of acute ischemic stroke in clinical practice. PMID:24258466

    The present work aimed to study the behavior of acute phase proteins (haptoglobin, serum amyloid A, acid soluble glycoprotein, fibrinogen, and albumin) in fasting-induced pregnancy toxemia in goats and their relationship with classical indicators of this disorder such as beta-hydroxybutyrate and nonesterified fatty acids in the blood and decreased urine pH and ketonuria. Twelve adult Murciano-Granadina goats at the final stage of gestation were used in this experiment. Pregnancy toxemia was induced in 6 goats by fasting for 72 hr. The other 6 animals were used as control group. Ketonuria was present in 4 out of 5 fasting animals at 24 hr and in all fasting animals at 48 hr of fasting. Serum nonesterified fatty acids were significantly increased at 24, 48, and 72 hr of fasting. Beta-hydroxybutyrate and haptoglobin achieved significantly increased concentrations at 48 hr and 72 hr, respectively, remaining increased during the entire study. Serum amyloid A, acid soluble glycoprotein, fibrinogen, and albumin were not affected by fasting. In conclusion, acute phase proteins (including haptoglobin) seemed not to have an advantage over traditional markers in diagnosis of fasting-induced pregnancy toxemia in goats. PMID:21217028

    The levels of two murine acute phase proteins, serum amyloid P component (SAP) and haptoglobin, have been measured in the serum of C57BL/10 female mice during syngeneic and allogeneic pregnancy. Both syngeneic and allogeneic pregnancy resulted in alterations in the levels of these proteins as compared to those observed in virgin females. Syngeneic mating resulted in an increase in concentration of both proteins during the final 3 days of pregnancy. During allogeneic pregnancy, SAP levels, after a transient increase on day 4, rose from days 6-8 and, after remaining relatively stable, increased from day 12 to reach maximum levels on day 18 of pregnancy. Levels fell dramatically during the immediate post-partum period. In contrast, although levels of haptoglobin also increased from days 6-8, for the remainder of pregnancy these increased levels remained stable. The implications of these findings are discussed in relation to the mechanisms of regulation of acute phase reactants and the immunological relationship between the mother and fetus. PMID:6409477

    OBJECTIVE—To determine prospectively the efficacy of surfactant in acute respiratory distress syndrome.
STUDY DESIGN—Twenty patients, 1 month to 16 years of age, diagnosed with an acute pulmonary disease with severe hypoxaemia (PaO2/FiO2 < 100) (13 with systemic or pulmonary disease and seven with cardiac disease) were treated with one to six doses of 50-200 mg/kg of porcine surfactant administered directly into the trachea. The surfactant was considered to be effective when the PaO2/FiO2 improved by > 20%.
RESULTS—After initial surfactant administration the PaO2/FiO2 increased significantly in patients with systemic or pulmonary disease from 68 to 111, and the oxygenation index (OI) diminished significantly from 36.9 to 27.1. The PaO2/FiO2 and OI did not improve in children with cardiac disease. The improvement of the patients who survived was greater than that of those who died.
CONCLUSIONS—Surfactant moderately improves oxygenation in some children with severe acute respiratory distress syndrome secondary to pulmonary or systemic disease.

    McBurney’s procedure represented the gold-standard for acute appendicitis until 1981, but nowadays the number of laparoscopic appendectomies has progressively increased since it has been demonstrated to be a safe procedure, with excellent cosmetic results and it also allows a shorter hospitalization, a quicker and less painful postoperative recovery. The aim of this editorial was to perform a review of the literature in order to address controversial issues in the treatment of acute appendicitis. PMID:24379603

    Background: Treatment of acute leukemia's- a common childhood malignancy, involves intensive and powerful multi-drug chemotherapeutic regime. Oral lesions are a common complication in these patients affecting oral health status. Aim: This study was conducted to evaluate and assess the oral health status of newly diagnosed leukemic pediatric patients during induction phase and its correlation to outcome of induction therapy. Material Methods: Oral examinations was done in 33 children between the age group of 5-15 years with acute lymphoblastic leukemia (ALL) and acute myloblastic leukemia (AML), who were undergoing chemotherapy. Oral Hygiene Index- Simplified, (OHI-S) decayed missing filled teeth index (def/DMFT), Loe and Sillness index for gingiva, and complete blood count at first and fourth week of induction phase were recorded for each patient. The changes in the oral health status were analyzed with Wilcoxon signed rank test. Results: During an induction phase it was observed that level of OHI-S (P = 0.002), Loe and Sillness index (P = 0.003), def/DMFT index (P = 0.076), platelet count (P = 0.00) increased significantly and no significant difference was noted in hemoglobin (P = 0.4) and total leucocytes count (P = 0.11). Conclusion: It was observed that, although oral health status had significantly worsened, the induction outcome was not affected. PMID:25006282

    RBP-7000 is a sustained-release formulation of risperidone for the treatment of schizophrenia, designed to be administered by once-monthly subcutaneous injection using the ATRIGEL delivery system. This study assessed the efficacy, safety, and tolerability of RBP-7000 compared with placebo in subjects with acute exacerbation of schizophrenia. Inpatients were randomly assigned to 8 weeks of double-blind treatment with subcutaneous 90 or 120 mg of RBP-7000 or placebo. Efficacy was evaluated using a mixed-model repeated-measures analysis of the change from baseline (the last nonmissing value before the first dose of RBP-7000 or placebo on day 1) to end of the study in Positive and Negative Syndrome Scale (PANSS) total score (primary efficacy measure) and Clinical Global Impression-Severity score (secondary efficacy measure). The least-squares means from the repeated-measures analysis for the change from baseline in the PANSS total scores for placebo was -9.219 (SE, 1.2162). RBP-7000 produced statistically and clinically significant differences in mean reductions from baseline in PANSS total scores (90-mg RBP-7000 compared with placebo, -6.148 [-9.982 to -2.314], P = 0.0004; 120-mg RBP-7000 compared with placebo, -7.237 [-11.045 to -3.429], P < 0.0001) and significantly improved Clinical Global Impression-Severity scores (90-mg RBP-7000 compared with placebo, -0.350 [-0.557 to -0.143], P = 0.0002; 120-mg RBP-7000 compared with placebo, -0.396 [-0.602 to -0.190], P < 0.0001). Both RBP-7000 dosages were generally well tolerated. The most frequently reported treatment-emergent adverse events in RBP-7000 groups compared with placebo were somnolence, weight gain, and akathisia. The overall incidence of extrapyramidal syndrome-related effects was low and similar across groups. RBP-7000 may provide a new, long-acting alternative treatment for use in adults with acute schizophrenia.

    Faropenem medoxomil is the first oral penem in a new class of beta-lactam antibiotics. Faropenem medoxomil has excellent in vitro activity against Streptococcus pneumoniae, Haemophilus influenzae and other key pathogens implicated in acute bacterial rhinosinusitis. Clinical studies have demonstrated that, in the treatment of acute bacterial rhinosinusitis in adults, 7 days of treatment with faropenem medoxomil is as clinically and bacteriologically effective as 10 days of treatment with cefuroxime axetil. One study showed faropenem medoxomil to be superior to cefuroxime axetil. Overall, the safety profile of faropenem medoxomil is similar to that of most comparators. Specifically, the minimal impact of faropenem medoxomil on the gastrointestinal flora leads to less diarrhea and other adverse events than coamoxicillin-clavulanate. Faropenem medoxomil has almost no drug-drug interactions and little requirement for dosage adjustments in the typical acute rhinosinusitis population. PMID:17181408

    Introduction: Acute intoxications with corrosive substances can cause severe chemical injuries of the upper gastrointestinal tract, most often located in the mouth, pharynx, esophagus, stomach and duodenum. If a patient survives the acute phase of intoxication, regenerative response may result in esophageal and/or gastric stenosis, and increased risk of esophageal and gastric cancer. Such intoxication may be fatal due to perforation or tracheal necrosis. Enteral nutrition is a nutritional method when nutritional substances are administered through specially designed tubing placed through the nose or percutaneously, directly into the GIT. Aim: The aim of this study is to describe the methods of artificial nutrition in patients with acute corrosive intoxications and the importance of nutritional support in the treatment of these intoxications. Discussion: Nutrition in the treatment of acute corrosive intoxications is one of the most important therapeutic processes that largely contribute to faster recovery of the post-corrosive injuries of upper GIT, stabilization of biologic, immunologic and metabolic parameters, and reduction of length of stay in hospital Aim of the treatment of acute corrosive intoxications is to prevent perforation and progressive fibrosis, and esophageal and gastric stenosis. There are different and often conflicting positions, on the conservative treatment of acute corrosive intoxications in adults. Such treatment mainly consists of anti-secretory treatment, antibiotics and intensive hyper-alimentation, aiming to prevent late post-corrosive intoxications. Conclusion: It is considered that nutritional support plays a major role in maintenance of metabolic processes and prevention of severe metabolic complications that could additionally aggravate the condition and impair the treatment.

    Objective: Acute ankle sprains are one of the most common injuries in emergency departments. Immobilization is widely accepted as the basic treatment modality for acute ankle sprains; however, immobilization method remains controversial. In this study, we aimed to compare two treatment modalities: splint and elastic bandage for the management of acute ankle sprains. Methods: This prospective study was conducted in the emergency department. Fifty-one consecutive patients who were admitted to the emergency department owing to the complaint of ankle sprain and who were treated with an elastic bandage or a splint were included in the study. After bone injury was ruled out, treatment choice was left to the on-shift physicians’ discretion. The extent of edema was evaluated before and after the treatment by using a small, graduated container filled with warm water. Volume differences were calculated by immersing both lower extremities in a container filled to a constant level. Pain was evaluated using the visual analogue scale. Results: There were 25 patients in the elastic bandage group and 26 patients in the splint group. VAS scores of these groups before and after the treatment were similar. Although edema size before and after the treatment were similar between the groups, edema size reduction was significantly more in the elastic bandage group [p=0,025]. Conclusions: This study showed that treatment of acute ankle sprains with an elastic bandage was more effective than splint in reducing edema. Therefore, an elastic bandage could be preferred over a splint for the treatment of acute ankle sprains. PMID:26870123

    Objective We examine remission rate probabilities, recovery rates, and residual symptoms across 36 weeks in the Treatment for Adolescents with Depression Study (TADS). Method TADS, a multisite clinical trial, randomized 439 adolescents with major depressive disorder (MDD) to 12 weeks of treatment to fluoxetine (FLX), cognitive behavioral therapy (CBT), their combination (COMB), or pill placebo (PBO). The PBO group, treated openly after week 12, was not included in the subsequent analyses. Treatment differences in remission rates and probabilities of remission over time are compared. Recovery rates in remitters at week 12 (acute phase remitters) and week 18 (continuation phase remitters) are summarized. We also examined whether residual symptoms at the end of 12 weeks of acute treatment predicted later remission. Results At Week 36, the estimated remission rates for intention-to-treat cases were: COMB: 60%, FLX: 55%; CBT: 64%; overall: 60%. Paired comparisons reveal that at week 24 all active treatments converge on remission outcomes. The recovery rate at Week 36 was 65% for acute phase remitters and 71% for continuation phase remitters, with no significant between-treatment differences in recovery rates. Residual symptoms at the end of acute treatment predicted failure to achieve remission at weeks 18 and 36. Conclusions The majority of depressed adolescents in all three treatment modalities achieved remission at the end of nine months of treatment. PMID:19127172

    Endovascular therapy for acute stroke has evolved with the use of intra-arterial thrombolytics, intravenous/intra-arterial bridging strategies, and mechanical thrombectomy/aspiration devices. Despite widespread use in clinical practice, randomized trials of first-generation devices failed to demonstrate improved outcomes compared with standard care. New-generation stent retriever devices demonstrate higher rates of revascularization and clinical outcomes compared with first-generation devices. Additional randomized trials are underway and have the potential to confirm clinical efficacy of new-generation devices compared with standard care. The role of additional advanced imaging for patient selection remains unclear, and further trials are needed to demonstrate the role of these techniques for patient selection. PMID:25907913

    PubMed

    2013-01-01

    Since inflammation has been linked to carcinogenic events, discovery of relevant biomarkers may have important preventative implications. Procalcitonin (ProCT) has been shown to be an important prognostic biomarker in severe inflammatory conditions, but there is no data regarding its biomarker role, if any, beyond the acute phase. In a recent study published in BMC Medicine, Cotoi et al. analyzed whether serum ProCT levels in healthy individuals are associated with mortality outcomes. The results are affirmative in that baseline ProCT was shown to be strongly and independently associated with all-cause and cancer mortality and with the incidence of colon cancer in men. By contrast, the study indicated that high sensitivity C-reactive protein was independently associated with cardiovascular mortality but not with cancer mortality in men. Thus, baseline levels of ProCT appear to have prognostic biomarker implications potentially related to its emerging biomediator action(s). PMID:23984981

    Acute compartment syndrome of the extremities is well known, but diagnosis can be challenging. Ineffective treatment can have devastating consequences, such as permanent dysaesthesia, ischaemic contractures, muscle dysfunction, loss of limb, and even loss of life. Despite many studies, there is no consensus about the way in which acute extremity compartment syndromes should be diagnosed. Many surgeons suggest continuous monitoring of intracompartmental pressure for all patients who have high-risk extremity injuries, whereas others suggest aggressive surgical intervention if acute compartment syndrome is even suspected. Although surgical fasciotomy might reduce intracompartmental pressure, this procedure also carries the risk of long-term complications. In this paper in The Lancet Series about emergency surgery we summarise the available data on acute extremity compartment syndrome of the upper and lower extremities in adults and children, discuss the underlying pathophysiology, and propose a clinical guideline based on the available data.

  12. How assess drugs in the treatment of acute bipolar mania?

    Bipolar affective disorder is a serious mental disease associated with significant morbidity and mortality. Good-quality research available to guide treatment strategies remains insufficient, particularly with regard to manic or hypomanic episodes. A critical review of the various stages of mania might be helpful for pharmaceutical companies and investigators as a prerequisite for the clinical evaluation of potential antimanic properties of medications. The main difficulty is with a comparison between anticonvulsants, antipsychotics, and mood stabilizers such as lithium (with equal efficacy in the acute phase and the prevention of recurrent manic episodes). No consensus has been reached with regard to the treatment of bouts of acute mania in various parts of the world. Controlled clinical trials have, at last, provided irrefutable evidence of the activity of lithium, which has long been used alone, as well as that of divalproate or its derivatives and, to a lesser extent, carbamazepine. The new antipsychotic agents have more recently established their efficacy, especially aripiprazole, asenapine, quetiapine; olanzapine, risperidone, and ziprasidone (not sure where the paradox is). In Europe, haloperidol is still the reference substance used in clinical trials despite the fact that it is not officially indicated in the treatment of mania. In the USA, lithium, divalproate, or antipsychotics can be prescribed as first-line treatment. In Europe, lithium remains the first-line medication, whereas divalproate and atypical antipsychotic agents are used only as second-line therapy. Although both types of medication (antipsychotics, normothymic agents, and/or anticonvulsants) have proved to be clinically effective in the management of mania by reducing the mania scores overall, the same does not apply, however, to all symptoms of mania. Factorial approaches to mania have all shown that since there are several clinical forms of mania, several clusters of manic symptoms can

    Purpose: A two-arm, double-blind, randomized trial was performed to evaluate the effect of 0.1% mometasone furoate (MMF) on acute skin-related toxicity in patients undergoing breast or chest wall radiotherapy. Methods and Materials: Patients with ductal carcinoma in situ or invasive breast carcinoma who were undergoing external beam radiotherapy to the breast or chest wall were randomly assigned to apply 0.1% MMF or placebo cream daily. The primary study endpoint was the provider-assessed maximal grade of Common Terminology Criteria for Adverse Events, version 3.0, radiation dermatitis. The secondary endpoints included provider-assessed Common Terminology Criteria for Adverse Events Grade 3 or greater radiation dermatitis and adverse event monitoring. The patient-reported outcome measures included the Skindex-16, the Skin Toxicity Assessment Tool, a Symptom Experience Diary, and a quality-of-life self-assessment. An assessment was performed at baseline, weekly during radiotherapy, and for 2 weeks after radiotherapy. Results: A total of 176 patients were enrolled between September 21, 2007, and December 7, 2007. The provider-assessed primary endpoint showed no difference in the mean maximum grade of radiation dermatitis by treatment arm (1.2 for MMF vs. 1.3 for placebo; p = .18). Common Terminology Criteria for Adverse Events toxicity was greater in the placebo group (p = .04), primarily from pruritus. For the patient-reported outcome measures, the maximum Skindex-16 score for the MMF group showed less itching (p = .008), less irritation (p = .01), less symptom persistence or recurrence (p = .02), and less annoyance with skin problems (p = .04). The group's maximal Skin Toxicity Assessment Tool score showed less burning sensation (p = .02) and less itching (p = .002). Conclusion: Patients receiving daily MMF during radiotherapy might experience reduced acute skin toxicity compared with patients receiving placebo.

    Meat tenderizer containing the proteolytic enzyme papain was tested for therapeutic efficacy in the sting of the imported fire ant. The parameters of pain and itching were used to evaluate qualitatively the sting response in 22 healthy medical students, and the laser Doppler velocimeter was used to assess quantitatively the change in cutaneous blood flow. The results indicated that, during the acute-phase reaction, no clinically or statistically significant difference was found between stings treated with meat tenderizer and stings treated without tenderizer. Therefore we conclude that meat tenderizer is of no therapeutic value in the acute treatment of the imported fire ant sting.

    During an acute viral infection, virus levels rise, reach a peak and then decline. Data and numerical solutions suggest the growth and decay phases are linear on a log scale. While viral dynamic models are typically nonlinear with analytical solutions difficult to obtain, the exponential nature of the solutions suggests approximations can be found. We derive a two-phase approximate solution to the target cell limited influenza model and illustrate the accuracy using data and previously established parameter values of six patients infected with influenza A. For one patient, the subsequent fall in virus concentration was not consistent with our predictions during the decay phase and an alternate approximation is derived. We find expressions for the rate and length of initial viral growth in terms of the parameters, the extent each parameter is involved in viral peaks, and the single parameter responsible for virus decay. We discuss applications of this analysis in antiviral treatments and investigating host and virus heterogeneities.

    An adequate treatment of ischaemic stroke in the early phase (28-48 h) is the most important factor for a better outcome. Thrombolysis with rTPA (within 3 h) and oral ASA 300 mg/days are the first therapeutic misures. Continuous monitoring of cardiological and haemodinamic parameters allows early detection of cardiac disturbances. Treatment of hypertension, low haematic oxigenation, hyperglicaemia, seizures and hypertermia is basic to improve outcome. Pharmacological therapy is only one of the components of effective multidisciplinary integrated management of ischaemic stroke; we remind also the precocity of rehabilitation procedures and an accurate psychological assessment.

    Summary Acute thrombosis of cerebral veins and sinuses (ATCVS) is a multifactorial disease with grave consequences. Because of its rare occurrence there are no proven treatment guidelines. Sixteen patients with ATCVS were treated. The final diagnosis was confirmed by digital subtraction angiography. Sinus catheterization was performed via transfemoral venous access. Treatment included mechanical manipulation of thrombi and thrombolytic therapy. A regression of clinical symptoms with a concomitant decrease of intracranial hypertension was achieved in all patients. Long-term results were studied in eight patients: none presented clinical signs of intracranial hypertension. Endovascular transvenous recanalization is an effective treatment for acute thrombosis of cerebral veins and sinuses. Along with the local thrombolysis, significant potential in the treatment of this complex pathology lies in the transvenous endovascular techniques of mechanical thrombus extraction, especially in patients with intracranial hemorrhage for whom the use of thrombolytic agents is restricted.

    The superiority of the pediatric protocol for adolescents with acute lymphoblastic leukemia (ALL) has already been demonstrated, however, its efficacy in young adults remains unclear. The ALL202-U protocol was conducted to examine the efficacy and feasibility of a pediatric protocol in adolescents and young adults (AYAs) with BCR-ABL-negative ALL. Patients aged 15-24 years (n=139) were treated with the same protocol used for pediatric B-ALL. The primary objective of this study was to assess the disease-free survival (DFS) rate and its secondary aims were to assess toxicity, the complete remission (CR) rate and the overall survival (OS) rate. The CR rate was 94%. The 5-year DFS and OS rates were 67% (95% confidence interval (CI) 58-75%) and 73% (95% CI 64-80%), respectively. Severe adverse events were observed at a frequency that was similar to or lower than that in children treated with the same protocol. Only insufficient maintenance therapy significantly worsened the DFS (hazard ratio 5.60, P<0.001). These results indicate that this protocol may be a feasible and highly effective treatment for AYA with BCR-ABL-negative ALL. PMID:25325302

    Abstract Question A 3-year-old was rushed to my office after eating a friend’s chocolate bar that contained nuts. He immediately developed urticaria on his face and swelling of his lips, and he had a persistent cough. What is the best treatment for a child with anaphylaxis? Should this family receive a prescription for an epinephrine autoinjector device? Answer Intramuscular epinephrine injection is a safe and effective treatment of anaphylaxis in children. Children with systemic allergic reactions should carry epinephrine autoinjectors at all times, and should certainly have one with them at school. In order for epinephrine autoinjectors to be effective, children and their families need to be educated on how to properly use the devices, as well as keep in mind the product’s expiration date.

    Bloom syndrome (BS) is an inherited genomic instability disorder caused by disruption of the BLM helicase and confers an extreme cancer predisposition. Here we report on a girl with BS who developed acute lymphoblastic leukaemia (ALL) at age nine, and treatment-related acute myeloid leukaemia (t-AML) aged 12. She was compound heterozygous for the novel BLM frameshift deletion c.1624delG and the previously described c.3415C>T nonsense mutation. Two haematological malignancies in a child with BS imply a fundamental role for BLM for normal haematopoiesis, in particular in the presence of genotoxic stress. PMID:24932421

    Over 90% of leukemic blasts in patients with acute lymphoblastic leukemia express the marker CD22. Inotuzumab ozogamicin (INO) is a CD22-directed humanized monoclonal antibody conjugated to the potent cytotoxin, calicheamicin, via an acid labile linker. INO has shown high rates of response in the treatment of relapsed and refractory (R/R) ALL in single-agent studies, with fewer adverse effects than traditional cytotoxic chemotherapy. Given this experience, studies are now being done to evaluate INO in combination with low-intensity chemotherapy as frontline treatment for older adults with ALL and patients with R/R disease. Herein we will discuss the use of INO in the treatment of acute lymphoblastic leukemia.

    Acute ischemic stroke is a morbid and disabling medical condition with a significant social and economic impact throughout the world. Intravenous thrombolysis (IVT) has been the first line treatment for patients presenting up to 4.5 hours after symptom onset for many years. Endovascular stroke treatment has been used successfully as rescue therapy after failed IVT; in patients with contraindications to rtPA or presenting outside the 4.5-hour window. The effectiveness of IVT is high for distal thrombi but significantly lower for proximal occlusions. Endovascular treatment has been revolutionized by the evolution from intra-arterial thrombolysis and first generation mechanical devices to the current generation of stent retrievers and aspiration systems with large bore catheters. These devices have been associated with excellent revascularization, improved clinical outcomes, shorter procedure times and reduced device and procedure related complications. We report the current literature, clinical standards and perspectives on mechanical thrombectomy in acute ischemic stroke.

    Chemotherapy remains the first-choice option for adjuvant therapy in breast cancer. Here, we investigated the impact of the first chemotherapic cycle of doxorubicin on the plasmatic-proteomic profiling of women diagnosed with breast cancer (n = 87). Blood samples were obtained from the same patient before and after doxorubicin infusion (1 h, 60 mg/m(2)) and processed for label-free LC-MS proteomic screening. A total of 80 proteins were downregulated after chemotherapy. In silico analysis revealed that the main biological process enrolled was inflammation and canonical pathways involving acute phase proteins. TNF-α, IL-1β, IL-12, TGF-β1, clusterin, and gelsolin were chosen as relevant for further validation. All selected targets presented reduced plasmatic levels after treatment. Our results indicate that doxorubicin downregulated acute phase proteins immediately after its infusion. Since such proteins are cancer promoting, its downregulation could support the effectiveness of doxorubicin along treatment. PMID:26472721

    The aims of this study were to investigate the level of acute phase proteins in dairy cows with urinary tract infection (UTI) and to evaluate their diagnostic and prognostic value. Eighty-four lactating cows with clinical and laboratory evidence of UTI and 15 healthy controls were included in this study. Serum samples were evaluated for the levels of Haptoglobin (Hp), serum amyloid A (SAA), fibrinogen (Fb), α1-Acid glycoprotein (AGP), total protein, and globulin. The diagnostic and prognostic performance of each parameter was evaluated by estimating the area under receiver operating characteristics curve (AUROC). Escherichia coli and Corynebacterium spp. were the primary bacteria associated with UTI. The levels of serum Hp, SAA, Fb, AGP, total protein, and globulin were significantly higher in UTI cows. Successfully treated cows (n = 51) had lower levels of Hp, SAA, AGP, total protein, and globulin than non-responsive cows. Overall, Hp, SAA, Fb, and AGP showed comparable diagnostic accuracy (AUROC ranged from 0.93 to 0.98). Both Hp and SAA showed high accuracy in predicting treatment response (AUROC > 0.95), whereas Fb level was of no prognostic value (AUROC = 0.48). From this study, acute phase proteins levels can be used as markers for UTI in cows and higher levels of Hp, SAA and AGP are related to poor treatment response. PMID:27348889

    How many times have you heard from a patient or groaned yourself "Oh, my aching back?" Innocuous movements such as reaching, stooping, or leaning are halted mid-performance as you sense "something" give, catch, snap, grab, or slide in your lower back. Such subjective complaints may also include sensations of discomfort described as stabbing, sharp, dull, hot/burning, tingling, or numbing. In practice, you will be required to assess these subjective symptoms, effectively document objective data, formulate a diagnosis, and plan appropriate treatment for your patients. Careful attention to history, associated symptoms, and following a systematic approach to back pain can make the rule-in/out differentials less taxing on both the practitioner and the patient.

    Objective The effect of induced hypothermia on severe acute carbon monoxide (CO) poisoning remains to be addressed further. We investigated the effect of induced hypothermia on severe acute CO poisoning. Methods Retrospective chart review was conducted for patients who diagnosed as severe acute CO poisoning in emergency department and underwent induced hypothermia from May 2013 to May 2014. Hospital courses with critical medication and major laboratory results were investigated through the chart review. Results Among total 227 patients with acute CO poisoning during the period of study, patients with severe acute CO poisoning were 15. All patients underwent induced hypothermia with a temperature goal 33°C. Initial and follow-up levels of S100B protein after induced hypothermia were 0.47 μg/L (interquartile range, 0.11 to 0.71) and 0.10 μg/L (interquartile range, 0.06 to 0.37), respectively (P = 0.01). The mean Glasgow Coma Scales at emergency department admission was 6.87 ± 3.36. Except 1 patient who expired after cardiopulmonary resuscitation, Glasgow Coma Scales at 30-day of hospital discharge were 15 in 10 patients (71.4%), 14 in 1 patient (7.1%), 13 in 1 patient (7.1%), and 6 in 2 patients (14.2%). Seven patients (46.7%) developed delayed neurologic sequelae. Four patients showed mild types of delayed neurologic sequelae and 3 showed moderate to severe types of delayed neurologic sequelae. Conclusion Most of patients underwent induced hypothermia had a good recovery from severe acute CO poisoning. Therefore, induced hypothermia may be considered as a possible treatment in severe acute CO poisoning. PMID:27752625

    Feed deprivation in poultry farming imposes some degree of stress to the birds, and adversely affects their well -being. Serum levels of acute phase proteins (APP) are potential physiological indicators of stress attributed to feed deprivation. However, it has not been determined how long it takes for a measurable APP response to stressors to occur in avian species. An experiment was designed to delineate the APP and circulating levels of corticosterone responses in commercial broiler chickens to feed deprivation for 30 h. It was hypothesized that feed deprivation would elicit both APP and corticosterone (CORT) reactions within 30 h that is probably associated with stress of hunger. Twenty-one day old birds were subjected to one of 5 feed deprivation periods: 0 (ad libitum, AL), 6, 12, 18, 24, and 30 h. Upon completion of the deprivation period, blood samples were collected to determine serum CORT, ovotransferrin (OVT), α1-acid glycoprotein (AGP), and ceruloplasmin (CP) concentrations. Results showed that feed deprivation for 24 h or more caused a marked elevation in CORT (P=0.002 and P<0.0001, respectively) when compared to AL. However, increases in AGP (P=0.0005), CP (P=0.0002), and OVT (P=0.0003) were only noted following 30 h of feed deprivation. It is concluded that elicitation of AGP, CP, and OVT response may represent a more chronic stressful condition than CORT response in assessing the well-being of broiler chickens.

    Purpose Painful oral mucositis (OM) is a significant toxicity during radiotherapy for head and neck cancers. The aim of this randomized, double-blind, placebo-controlled trial was to test the efficacy of doxepin hydrochloride in the reduction of radiotherapy-induced OM pain. Patients and Methods In all, 155 patients were randomly allocated to a doxepin oral rinse or a placebo for the treatment of radiotherapy-related OM pain. Patients received a single dose of doxepin or placebo on day 1 and then crossed over to receive the opposite agent on a subsequent day. Pain questionnaires were administered at baseline and at 5, 15, 30, 60, 120, and 240 minutes. Patients were then given the option to continue doxepin. The primary end point was pain reduction as measured by the area under the curve (AUC) of the pain scale using data from day 1. Results Primary end point analysis revealed that the AUC for mouth and throat pain reduction was greater for doxepin (−9.1) than for placebo (−4.7; P < .001). Crossover analysis of patients completing both phases confirmed that patients experienced greater mouth and throat pain reduction with doxepin (intrapatient changes of 4.1 for doxepin-placebo arm and −2.8 for placebo-doxepin arm; P < .001). Doxepin was associated with more stinging or burning, unpleasant taste, and greater drowsiness than the placebo rinse. More patients receiving doxepin expressed a desire to continue treatment than did patients with placebo after completion of each of the randomized phases of the study. Conclusion A doxepin rinse diminishes OM pain. Further studies are warranted to determine its role in the management of OM. PMID:24733799

    Clinical case reports and prospective trials have demonstrated a reproducible benefit of hypothalamic-pituitary-adrenal (HPA) axis modulation on the rate of recovery from acute inflammatory central nervous system (CNS) demyelination. As a result, corticosteroid preparations and adrenocorticotrophic hormones are the current mainstays of therapy for the treatment of acute optic neuritis (AON) and acute demyelination in multiple sclerosis. Despite facilitating the pace of recovery, HPA axis modulation and corticosteroids have failed to demonstrate long-term benefit on functional recovery. After AON, patients frequently report visual problems, motion perception difficulties and abnormal depth perception despite ‘normal’ (20/20) vision. In light of this disparity, the efficacy of these and other therapies for acute demyelination require re-evaluation using modern, high-precision paraclinical tools capable of monitoring tissue injury. In no arena is this more amenable than AON, where a new array of tools in retinal imaging and electrophysiology has advanced our ability to measure the anatomic and functional consequences of optic nerve injury. As a result, AON provides a unique clinical model for evaluating the treatment response of the derivative elements of acute inflammatory CNS injury: demyelination, axonal injury and neuronal degeneration. In this article, we examine current thinking on the mechanisms of immune injury in AON, discuss novel technologies for the assessment of optic nerve structure and function, and assess current and future treatment modalities. The primary aim is to develop a framework for rigorously evaluating interventions in AON and to assess their ability to preserve tissue architecture, re-establish normal physiology and restore optimal neurological function.

    Procalcitonin is a protein which is found in elevated concentrations in the blood circulation during systemic bacterial, fungal or protozoal infection. In contrast to classical acute-phase proteins like C-reactive protein or interleukin-6, it is not elevated after operative trauma. In this paper we present current opinions on the assumed induction mechanisms of the protein by cytokines and endotoxin. Furthermore, the clinical value for early detection of systemic infections in abdominal and transplantation surgery is demonstrated by examples from the literature. Our investigation shows that eight patients with necrotizing pancreatitis had a PCT mean value of 6.9 ng/ml on the day of admission. Seven patients with edematous pancreatitis had only a PCT mean value of 0.69 ng/ml. Despite these differences in the mean values, a significant difference between the normal value and the mean value of the group with necrotizing pancreatitis or edematous pancreatitis was not observed due to the wide range of PCT levels in the group of patients with necrotizing pancreatitis. The fact that only a few of the patients had a superinfected necrosis with systemic evasion of bacterias or their toxins may be the reason for this wide range. We suggest that a discrimination between superinfected necrotizing or sterile pancreatitis and edematous pancreatitis by PCT could be possible but more extensive studies with microbiological examination of the necrotic material are required to recognize the subgroups and to establish the real diagnostic efficiency of PCT in clinical practice, especially in the prediction of the outcome of acute pancreatitis.

    To assess the symptoms and signs of acute otitis media and efficiency of simple antibiotics like amoxicillin in its treatment in the primary health care setup. This is a prospective longitudinal study including 204 patients from different institutions. Patients were diagnosed as suffering from acute otitis media when presented with earache, fever, fullness and or otorrhea. Patients were divided into two equal groups on basis of the treatment they received, Group A received only symptomatic treatment while Group B were given Amoxicillin (40 mg/kg/day) for 7 days. Acute otitis media was common in children under 15 years (64.7%). Patients presented with earache (100%), aural fullness (90.68%), fever (76.47%) associated with recent onset of upper respiratory tract infections (88.23%). In group A, improvement was noticed in 28.43% in 3 days while 35.29% in 7 days. In group B, improvement was noticed in 48.03% in day 3 while 86.27% in day 7. In countries where medical care is scarce, patients lost to follow up, it is wise to treat with simple antibiotics like amoxicillin in adequate dose than to treat only symptomatically. It prevents chronicity, early hearing impairments and reduces antibiotic resistance.

  17. The onset of the progression of acute phase response mechanisms induced by extreme impacts can be followed by the decrease in blood levels of positive acute phase proteins.

    Studies performed at space flights and earth-based simulation models detected the plasma indices of acute phase reaction (APR), i.e. the increase of APR cytokine mediators and alterations in the production of blood acute phase proteins (APP) at the initial stages of adaptation to altered gravity conditions. Acute phase response is the principal constituent of the functional activity of innate immunity system. Changes in plasma APPs contents are considered to serve the restoration of homeostasis state. According to trends of their concentration shifts at the evolving of acute phase reaction APPs are denoted as positive, neutral, or negative. Plasma concentrations of positive acute phase proteins α1-acid glycoprotein (α1-AGP), α1-antitrypsin (α1-AT), and neutral α2-macroglobulin (α2-M) were measured in human study at 12-hour antiorthostatic position (AOP) with 15° head down tilt and hypoxia experiments at 14% oxygen in pressure chamber. Both of these impacts were shown to produce alterations in the APP levels indicative for acute phase response. Nevertheless, in AOP experiment noticeable decrease in α1-AGP concentration occurred by hour 12, and even more pronounced decline of α1-AGP and α1-AT were found on hypoxia hours 12 and 36. Acute phase proteins α1-AGP and α2-M possess the features of proteinase inhibitors. This function is implemented by the formation of complexes with the molecules of proteolytic enzymes which subsequently are removed from the blood flow. Transient decrease in plasma concentrations of protease inhibitors on early phases of APR development was reported to result from the growth of plasma protease activity due to cathepsin release from activated leukocytes, which had not yet been compensated by enhanced APP synthesis. Being a carrier protein for positively charged and neutral substances, α1-AGP shows pronounced elevation in its blood content during APR development. As assumed, it is required for the transportation of the increased

    The periparturient period is one of the most critical periods in the productive life of a dairy cow, and is the period when dairy cows are most susceptible to developing new intramammary infections (IMI) leading to mastitis. Acute phase proteins (APP) such as haptoglobin (Hp), mammary associated serum amyloid A3 (M-SAA3) and C-reactive protein (CRP) have been detected in milk during mastitis but their presence in colostrum and milk in the immediate postpartum period has had limited investigation. The hypothesis was tested that APP are a constituent of colostrum and milk during this period. Enzyme linked immunosorbent assays (ELISAs) were used to determine each APP's concentration in colostrum and milk collected daily from the first to tenth day following calving in 22 Holstein-Friesian dairy cows. Haptoglobin was assessed in individual quarters and composite milk samples while M-SAA3 and CRP concentration were determined in composite milk samples. Change in Hp in relation to the high abundance proteins during the transition from colostrum to milk were evaluated by 1 and 2 dimension electrophoresis and western blot. In 80% of the cows all APPs were detected in colostrum on the first day following parturition at moderately high levels but gradually decreased to minimal values in the milk by the 6th day after calving. The remaining cows (20%) showed different patterns in the daily milk APP concentrations and when an elevated level is detected could reflect the presence of IMI. Demonstration that APP are present in colostrum and milk following parturition but fall to low levels within 4 days means that elevated APP after this time could be biomarkers of post parturient mastitis allowing early intervention to reduce disease on dairy farms.

    Depression is a risk factor for morbidity and mortality in patients with coronary heart disease (CHD), especially following acute coronary syndrome (ACS). Evidence from recent clinical trials suggests that treatment-resistant depression may be associated with a particularly high risk of mortality or cardiac morbidity in post-ACS patients. This manuscript reviews this evidence, and considers possible explanations for this relationship. Directions for future research are also considered, with particular emphasis on efforts to elucidate the underlying mechanisms and to develop more efficacious treatments for depression in patients with CHD.

    The management of acute episodes in schizophrenia is frequently initiated in the psychiatric emergency department and requires rapid intervention to relieve distress and psychiatric symptoms. Both non-pharmacological and pharmacological interventions are needed to calm the patient and prevent potential harm to the patient or others. Treatment is a step-by-step process including management of behavioral symptomatology, diagnosis of potential organic causes, and evaluation of potential substance abuse. Better care is delivered if predefined standard operating procedures are adopted systematically. The ultimate goal of treatment is to establish a therapeutic alliance with the patient. Atypical antipsychotics given orally are recommended as a first-line treatment. As the treatment endpoint is calmness rather than sleep, a non-sedative antipsychotic agent is usually preferred. Drug tolerance is a major issue for the patient. Amisulpride is an effective atypical antipsychotic agent in this context. The optimal dose is 800 mg/day, which is effective on positive and negative symptoms and can be given from the first day with a low risk of extrapyramidal symptoms. Since drug–drug interactions are limited, agitation and anxiety may be controlled by short-term adjunctive therapy with benzodiazepines. In conclusion, amisulpride is an appropriate first-line treatment for the management of acute psychosis. PMID:18360610

    2006-01-01

    The recently published Clinical Practice Guideline for the Diagnosis and Management of Acute Otitis Media represents a sincere effort by the AAP andthe AAFP to provide management guidelines for the practitioner based upon the best scientific evidence available. Despite many years of research and hundreds of clinical studies addressing various aspects of the epidemiology, clinical presentation, and treatment of acute otitis media, important questions remain unaddressed or have been addressed in a less than optimal fashion. These gaps in knowledge and deficiencies in several of the studies that formed the scientific basis for the proposed guidelines are the major reasons behind continued disagreement over certain recommendations. Until more comprehensive and careful analyses can be performed, disagreements are likely to persist. Even so, there is general agreement about most of the recommendations made in these guidelines, and these recommendations will provide a very valuable framework for the practicing physician as he or she cares for children with acute otitis media. To briefly review the major points, first is the critical importance of accurately diagnosing acute otitis media using a combination of clinical findings and observable abnormalities of the tympanic membrane and middle ear space. Particularly important is the differentiation of acute otitis media from otitis media with effusion. Second is the value of treating the pain associated with acute otitis media as a regular component of care, irrespective of any decision concerning antimicrobial treatment. Third is the option, for a select group of older patients with nonsevere disease, of withholding antimicrobial therapy for the first 48 to 72 hours, if close follow-up and active parental involvement can be guaranteed. Fourth is the recommendation that if an antimicrobial agent is used, high-dose amoxicillin (80 to 90 mg/kg/d) is the treatment of choice for most children at the time of initial presentation

    This study had been performed to investigate the anatomic and functional outcomes of nepafenac 0.1% therapy in acute central serous chorioretinopathy (CSC). The medical records of 30 patients with acute CSC were reviewed for a total of 31 eye charts. Seventeen eye records of 16 patients who were treated with topical nepafenac 0.1% three times daily for four weeks and continued until complete resolution of subretinal fluid were appraised. Fourteen patients with acute CSC (a total of 14 eye records) who did not receive treatment served as the control group also had been recorded. The proportion of eyes with complete resolution of subretinal fluid, serial changes in the mean best corrected visual acuity (BCVA), and the mean central foveal thickness (CFT) at 6 months of therapy were the outcomes measured. Mean age was 42.6±8.2 years in the treatment group and 41.1±7.1 years in the control group (p=0.85). At 6 months, 14 eyes (82.3%) in the treatment group and 6 eyes (42.8%) in the control group revealed a complete resolution in the subretinal fluid (p=0.02). In the treatment group, mean BCVA (LogMAR) significantly improved from 0.19±0.17 at baseline to 0.09±0.12 at 6 months (p=0.01). In the control group, mean BCVA (LogMAR) was 0.13±0.14 at baseline and decreased to 0.1±0.11 at 6 months (p=0.28). In the treatment group, mean CFT was 349±115 µm at baseline and significantly improved to 221±95 µm at 6 months (p<0.01). In the control group, mean CFT declined from 391±138 µm at baseline to 301±125 µm at 6 months (p=0.06). No treatment-related ocular or systemic side effects were observed. In conclusion, nepafenac 0.1% has the potential to treatment acute CSC. Further trials are warranted to study its safety and efficacy for this disease. PMID:24822228

    Dosing protocol and analgesic efficacy have been proposed to be important determinants of the magnitude of opioid tolerance. The present study examined the effect of acute, intermittent and continuous treatment with the low analgesic efficacy agonist morphine on analgesic tolerance. Mice were implanted s.c. with a 25 mg morphine pellet for 1-7 days. Other mice were implanted s.c. with two 25 mg, or one 75 mg morphine pellet for 7 days. The release of morphine from subcutaneous implanted pellets was quantitated using a spectrophotometric assay. In other studies, mice were injected with morphine once (18.5-185 mg/kg/day; approximately 10-100 times ED(50) for morphine analgesia) or once/day for 7 days. Controls were implanted with a placebo pellet or injected with saline. Analysis of drug release from a 25 mg pellet indicated that release was greatest during the first 24 h, declined and then remained relatively constant. The amount of morphine released over 7 days by a 75 mg pellet (23.9 mg) was more than that of a single 25 mg pellet (15.4 mg) but less than two 25 mg pellets (30.8 mg). Following treatment, morphine cumulative dose-response studies were conducted (tail flick). Continuous treatment with morphine using pellet implantation produced a dose-dependent shift in the morphine ED(50) by 3.3, 5.8 and 8.5 fold for one 25 mg pellet, one 75 mg pellet and two 25 mg pellets, respectively. Acute and intermittent morphine administration produced substantially less analgesic tolerance than continuous release of morphine by implant pellets. The maximum shift in the ED(50) was 1.6 for acute treatment and 2.7 for 7 day intermittent treatment; despite a larger total daily dose. The present results indicate that continuous treatment with morphine results in greater analgesic tolerance than acute or intermittent morphine treatment even at comparable daily doses. These results are consistent with the suggestion that intermittent dosing has reduced risk of producing opioid

    Background: The orbital complications account for about 80% of all complications secondary to acute rhinosinusitis. If the treatment is not correct and in time, orbital complications could progress rapidly, leading to optic neuritis, cavernous sinus thrombophlebitis or life-threatening intracranial complications. Aims: To evaluate the therapeutic efficacy of conservative therapy for the patients with orbital cellulitis and endoscopic sinus surgery (ESS) performed on patients with subperiosteal abscess (SPA) secondary to acute rhinosinusitis in children. Study Design: Retrospective cross-sectional study. Methods: The retrospective study included 31 pediatric patients with orbital complications secondary to acute rhinosinusitis. In all cases, intensive treatment was initiated with a combination of oral or intravenous antibiotics, glucocorticoid and gelomyrtol forte after admission. ESS was performed if an improvement in the condition of patients did not occur after 48 hours. However, the patients with orbital SPA, motility disorders of eyeball or decreased vision received ESS immediately within 24 hours. Results: Sixteen patients were cured by conservative therapy and 15 patients by ESS. All of the signs and symptoms disappeared after conservative therapy or ESS. There were no recurrences within the follow-up period of 1 to 8 years. Conclusion: Conservative therapy is an effective method for patients with inflammatory edema and most cases of orbital cellulitis in children. SPA can be cured by ESS.

If the treatment is not correct and in time, orbital complications could progress rapidly, leading to optic neuritis, cavernous sinus thrombophlebitis or life-threatening intracranial complications. Aims: To evaluate the therapeutic efficacy of conservative therapy for the patients with orbital cellulitis and endoscopic sinus surgery (ESS) performed on patients with subperiosteal abscess (SPA) secondary to acute rhinosinusitis in children. Study Design: Retrospective cross-sectional study. Methods: The retrospective study included 31 pediatric patients with orbital complications secondary to acute rhinosinusitis. In all cases, intensive treatment was initiated with a combination of oral or intravenous antibiotics, glucocorticoid and gelomyrtol forte after admission. ESS was performed if an improvement in the condition of patients did not occur after 48 hours. However, the patients with orbital SPA, motility disorders of eyeball or decreased vision received ESS immediately within 24 hours. Results: Sixteen patients were cured by conservative therapy and 15 patients by ESS. All of the signs and symptoms disappeared after conservative therapy or ESS. There were no recurrences within the follow-up period of 1 to 8 years. Conclusion: Conservative therapy is an effective method for patients with inflammatory edema and most cases of orbital cellulitis in children. SPA can be cured by ESS. PMID:27606135

    IL-1 generation by mononuclear phagocytes, IL-4 production by Th2 lymphocytes and IgE levels in serum were measured in eight patients with acute fasciolosis and seven patients in the chronic stage of the disease before and after triclabendazole treatment. Results were compared with those of a control group of ten individuals. The monocytes and lymphocytes from patients with acute and chronic fasciolosis produced significantly lower levels of IL-1 and IL-4 respectively, particularly in the chronic phase of the disease, as compared to the control. A significant increase in IgE level in both acute and chronic fasciolosis was observed. The level was significantly higher in acute as compared to chronic cases. After treatment with triclabendazole IL-1, IL-4 and IgE levels moved towards the control indicating obvious improvement in the immunological responses of the patients.

    Clinical experience with hydroxocobalamin in acute cyanide poisoning via ingestion remains limited. This case concerns a 35-year-old mentally ill woman who consumed more than 20 apricot kernels. Published literature suggests each kernel would have contained cyanide concentrations ranging from 0.122 to 4.09 mg/g (average 2.92 mg/g). On arrival, the woman appeared asymptomatic with a raised pulse rate and slight metabolic acidosis. Forty minutes after admission (approximately 70 min postingestion), the patient experienced headache, nausea and dyspnoea, and was hypotensive, hypoxic and tachypnoeic. Following treatment with amyl nitrite and sodium thiosulphate, her methaemoglobin level was 10%. This prompted the administration of oxygen, which evoked a slight improvement in her vital signs. Hydroxocobalamin was then administered. After 24 h, she was completely asymptomatic with normalised blood pressure and other haemodynamic parameters. This case reinforces the safety and effectiveness of hydroxocobalamin in acute cyanide poisoning by ingestion.

  13. Emerging therapies for treatment of acute lung injury and acute respiratory distress syndrome.

    2007-09-01

    Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a life-threatening form of respiratory failure that affects a heterogeneous population of critically ill patients. Although overall mortality appears to be decreasing in recent years due to improvements in supportive care, there are presently no proven, effective pharmacological therapies to treat ARDS and prevent its associated complications. The most common cause of death in ARDS is not hypoxemia or pulmonary failure, but rather multiple organ dysfunction syndrome (MODS), suggesting that improving survival in patients with ARDS may be linked to decreasing the incidence or severity of MODS. The key to developing novel treatments depends, in part, on identifying and understanding the mechanisms by which ARDS leads to MODS, although the heterogeneity and complexity of this disorder certainly poses a challenge to investigators. Novel therapies in development for treatment of ALI/ARDS include exogenous surfactant, therapies aimed at modulating neutrophil activity, such as prostaglandin and complement inhibitors, and treatments targeting earlier resolution of ARDS, such as beta-agonists and granulocyte macrophage colony-stimulating factor. From a clinical perspective, identifying subpopulations of patients most likely to benefit from a particular therapy and recognising the appropriate stage of illness in which to initiate treatment could potentially lead to better outcomes in the short term.

    We previously demonstrated vast expansion of hypoxic areas in the leukemic microenvironment and provided a rationale for using hypoxia-activated prodrugs. PR104 is a phosphate ester that is rapidly hydrolyzed in vivo to the corresponding alcohol PR-104A and further reduced to the amine and hydroxyl-amine nitrogen mustards that induce DNA cross-linking in hypoxic cells under low oxygen concentrations. In this phase I/II study, patients with relapsed/refractory acute myeloid leukemia (n=40) after 1 or 2 prior treatments or acute lymphoblastic leukemia (n=10) after any number of prior treatments received PR104; dose ranged from 1.1 to 4 g/m2. The most common treatment-related grade 3/4 adverse events were myelosuppression (anemia 62%, neutropenia 50%, thrombocytopenia 46%), febrile neutropenia (40%), infection (24%), and enterocolitis (14%). Ten of 31 patients with acute myeloid leukemia (32%) and 2 of 10 patients with acute lymphoblastic leukemia (20%) who received 3 g/m2 or 4 g/m2 had a response (complete response, n=1; complete response without platelet recovery, n=5; morphological leukemia-free state, n=6). The extent of hypoxia was evaluated by the hypoxia tracer pimonidazole administered prior to a bone marrow biopsy and by immunohistochemical assessments of hypoxia-inducible factor alpha and carbonic anhydrase IX. A high fraction of leukemic cells expressed these markers, and PR104 administration resulted in measurable decrease of the proportions of hypoxic cells. These findings indicate that hypoxia is a prevalent feature of the leukemic microenvironment and that targeting hypoxia with hypoxia-activated prodrugs warrants further evaluation in acute leukemia. The trial is registered at clinicaltrials.gov identifier: 01037556. PMID:25682597

    In the world, hereditary angioedema (HAE) affects 1 every 50000 persons. It is characterized by highly disabling and recurrent episodes of cutaneous, abdominal and laryngeal episodes of angioedema. Asphyxia related mortality ranges from 15 to 50%. In Argentina a plasma derived C1 inhibitor concentrate (pdC1INH) has been available for the treatment of acute attacks for many decades, however, only15 (26%) out of 58 patients had received pdC1INH at least once until 2008, and only2 (3.4%) had used it regularly. After worldwide approval of the new drugs for the treatment of acute HAE attacks, adding icatibant to pdC1INH in Argentina, and after publication of the therapeutic guide for the country, 42 (82%) out of 51 patients from the original group has pdC1INH available to treat their next attack. However, 16 (18%) patients continue without access to medication and other 15 (35.7%) obtain their therapy spuriously through some other affected relative in their environment. Only 12 (28.6%) patients of the group self-treated at home. Access to treatment has greatly improved, but needs to be extended to all patients and self-treatment at home should be encouraged.

    Although intravenous administration of tissue plasminogen activator is the only proven treatment after acute ischemic stroke, there is always a concern of hemorrhagic risk after thrombolysis. Therefore, selection of patients with potential benefits in overcoming potential harms of thrombolysis is of great importance. Despite the practical issues in using magnetic resonance imaging (MRI) for acute stroke treatment, multimodal MRI can provide useful information for accurate diagnosis of stroke, evaluation of the risks and benefits of thrombolysis, and prediction of outcomes. For example, the high sensitivity and specificity of diffusion-weighted image (DWI) can help distinguish acute ischemic stroke from stroke-mimics. Additionally, the lesion mismatch between perfusion-weighted image (PWI) and DWI is thought to represent potential salvageable tissue by reperfusion therapy. However, the optimal threshold to discriminate between benign oligemic areas and the penumbra is still debatable. Signal changes of fluid-attenuated inversion recovery image within DWI lesions may be a surrogate marker for ischemic lesion age and might indicate risks of hemorrhage after thrombolysis. Clot sign on gradient echo image may reflect the nature of clot, and their location, length and morphology may provide predictive information on recanalization by reperfusion therapy. However, previous clinical trials which solely or mainly relied on perfusion-diffusion mismatch for patient selection, failed to show benefits of MRI-based thrombolysis. Therefore, understanding the clinical implication of various useful MRI findings and comprehensively incorporating those variables into therapeutic decision-making may be a more reasonable approach for expanding the indication of acute stroke thrombolysis.

    Objective To determine the extent to which prospectively identified responders to cognitive therapy (CT) for recurrent major depressive disorder (MDD) hypothesized to be lower risk show significantly less relapse/recurrence than treated higher risk counterparts across 32 months. Method Outpatients (N = 523), aged 18–70, with recurrent MDD received 12–14 weeks of CT. The last seven consecutive scores from the Hamilton Rating Scale for Depression (HRSD-17), were used to stratify/define responders (n = 290) into lower (seven HRSD-17 scores of ≤ 6; n = 49; 17%) and higher risk (n = 241; 83%). The lower risk entered the 32-month follow-up. Higher risk patients were randomized to 8 months of continuation-phase CT or clinical management plus double-blind fluoxetine or pill placebo, with a 24-month follow-up. Results Lower risk patients were significantly less likely to relapse over the first 8 months compared to higher risk (Kaplan-Meier [KM] estimates (i.e., 4.9%=lower risk; 22.1%= higher risk; log-rank χ2 = 6.83, p = .009). This increased risk was attenuated, but not completely neutralized, by active continuation-phase therapy. Over the subsequent 24 months, the lower and higher risk groups did not differ in relapse/recurrence risk. Conclusions Rapid and sustained acute-phase CT remission identifies responders who do not require continuation-phase treatment to prevent relapse (i.e., return of an index episode). To prevent recurrence (i.e., new episodes), however, strategic allocation and more frequent “dosing” of CT and/or targeted maintenance-phase treatments may be required. Longitudinal follow-up is recommended. PMID:26654211

    Forty-five adolescent and preadolescent patients (42 females, three males) with anorexia nervosa (AN) were treated in a pediatric day care unit of a large urban hospital by a multidisciplinary team. In our treatment model, the pediatrician has the responsibility for the initial evaluation and physical rehabilitation while the pediatric psychiatrist does the initial evaluation of the patient and family and is available for intervention in an emergency. Parents are actively involved in the treatment program. Family psychotherapy is recommended for each patient and his or her family. Among 45 patients, 24 did not enter psychotherapy during the first 2 months of the refeeding period, while the remaining 21 patients started psychotherapy (family and/or individual) during this period. Weight gain was higher in the group without formal psychotherapy during the initial period of refeeding (7.3 +/- 3.1 kg versus 5 +/- 2.5 kg; p less than 0.01). It is suggested that the initiation of structured psychotherapy is not mandatory and does not contribute to treatment effectiveness in the acute phase when emaciation and negativism may hinder the psychotherapeutic process. We believe a multidisciplinary team, together with the parents, is the treatment of choice during the acute phase of AN.

    Elevated degree of body fatness and changes in other body composition parameters are known to be common effects of treatment for acute lymphoblastic leukemia (ALL) in children. In order to study peculiarities of somatic growth and development in ALL survivors, we describe the results of BIA body composition analysis of 112 boys and 108 girls aged 5-18 years in remission from ALL (remission time range 1-13 years) compared to data from the same number of age- and sex-matched healthy controls (n=220). Detrimental effect on height in ALL boys was observed, whereas girls experienced additional weight gain compared to healthy subjects. In ALL patients, resistance, body fat, and percent body fat were significantly increased. The reactance, phase angle, absolute and relative values of skeletal muscle and body cell mass were significantly decreased. Principal component analysis revealed an early prevalence of adiposity traits in the somatic growth and development of ALL girls compared to healthy controls.

    Objectives: We report the pathophysiology and treatment results of type A acute aortic dissection from our 20-year experience. Methods: We studied 673 patients with type A acute aortic dissection who underwent initial treatment from 1994 through July 2014. We divided these patients into two groups. The former group comprised 448 patients from 1994 through 2008, and the latter group comprised 225 patients from 2009 onward, when the current strategy of initial treatment and surgical technique including the early organ reperfusion therapies were established. Results: Women were significantly often presented than men in patients over 60 years of age. Thrombosed-type dissection accounted for more than half in patients over 70 years, and significantly often complicated pericardial effusion and cardiac tamponade than patent type. Malperfusion occurred in 26% of patients. Central repair operations were performed in 579 patients. In-hospital mortality for all patients was 15%, and for the patients who underwent central repair operations was 10%. Former period of operation, malperfusion, and preoperative cardiopulmonary arrest were significant risk factor of in-hospital death. Preoperative left main trunk (LMT) stents were placed in eight patients and superior mesenteric artery (SMA) intervention was performed in five, they were effective to improve the outcome. From 2009 onward, in-hospital mortality was 5.0% and there was no significant risk factor. Conclusion: Surgical results of type A acute aortic dissection were dramatically improved in the past 20 years. Early reperfusion strategy for the patients with malperfusion improved the outcomes.

  2. Treatment of acute non-anion gap metabolic acidosis.

    PubMed

    Kraut, Jeffrey A; Kurtz, Ira

    2015-02-01

    Acute non-anion gap metabolic acidosis, also termed hyperchloremic acidosis, is frequently detected in seriously ill patients. The most common mechanisms leading to this acid-base disorder include loss of large quantities of base secondary to diarrhea and administration of large quantities of chloride-containing solutions in the treatment of hypovolemia and various shock states. The resultant acidic milieu can cause cellular dysfunction and contribute to poor clinical outcomes. The associated change in the chloride concentration in the distal tubule lumen might also play a role in reducing the glomerular filtration rate. Administration of base is often recommended for the treatment of acute non-anion gap acidosis. Importantly, the blood pH and/or serum bicarbonate concentration to guide the initiation of treatment has not been established for this type of metabolic acidosis; and most clinicians use guidelines derived from studies of high anion gap metabolic acidosis. Therapeutic complications resulting from base administration such as volume overload, exacerbation of hypertension and reduction in ionized calcium are likely to be as common as with high anion gap metabolic acidosis. On the other hand, exacerbation of intracellular acidosis due to the excessive generation of carbon dioxide might be less frequent than in high anion gap metabolic acidosis because of better tissue perfusion and the ability to eliminate carbon dioxide. Further basic and clinical research is needed to facilitate development of evidence-based guidelines for therapy of this important and increasingly common acid-base disorder.

    Acute appendicitis (AA) is among the most common cause of acute abdominal pain. Diagnosis of AA is challenging; a variable combination of clinical signs and symptoms has been used together with laboratory findings in several scoring systems proposed for suggesting the probability of AA and the possible subsequent management pathway. The role of imaging in the diagnosis of AA is still debated, with variable use of US, CT and MRI in different settings worldwide. Up to date, comprehensive clinical guidelines for diagnosis and management of AA have never been issued. In July 2015, during the 3rd World Congress of the WSES, held in Jerusalem (Israel), a panel of experts including an Organizational Committee and Scientific Committee and Scientific Secretariat, participated to a Consensus Conference where eight panelists presented a number of statements developed for each of the eight main questions about diagnosis and management of AA. The statements were then voted, eventually modified and finally approved by the participants to The Consensus Conference and lately by the board of co-authors. The current paper is reporting the definitive Guidelines Statements on each of the following topics: 1) Diagnostic efficiency of clinical scoring systems, 2) Role of Imaging, 3) Non-operative treatment for uncomplicated appendicitis, 4) Timing of appendectomy and in-hospital delay, 5) Surgical treatment 6) Scoring systems for intra-operative grading of appendicitis and their clinical usefulness 7) Non-surgical treatment for complicated appendicitis: abscess or phlegmon 8) Pre-operative and post-operative antibiotics.

  4. Morphine in the treatment of acute pulmonary oedema--Why?

    PubMed

    2016-01-01

    Morphine has for a long time, been used in patients with acute pulmonary oedema due to its anticipated anxiolytic and vasodilatory properties, however a discussion about the benefits and risks has been raised recently. A literature search in Medline and Embase using the keywords "pulmonary oedema" OR "lung oedema" OR "acute heart failure" AND "morphine" was performed. A certain vasodilation has been described after morphine administration, but the evidence for this mechanism is relatively poor and morphine-induced anxiolysis may possibly be the most important factor of morphine in pulmonary oedema and therefore some authors have suggested benzodiazepines as an alternative treatment. Respiratory depression seems to be a less relevant clinical problem according to the literature, whereas vomiting is common, which may cause aspiration. In the largest outcome study, based on the ADHERE registry, morphine given in acute decompensated heart failure was an independent predictor of increased hospital mortality, with an odds ratio of 4.8 (95% CI: 4.52-5.18, p<0.001). Other, smaller studies have shown a significant association between morphine administration and mortality, which was lost after adjusting for confounding factors. Morphine is still used for pulmonary oedema in spite of poor scientific background data. A randomised, controlled study is necessary in order to determine the effect--and especially the risk--when using morphine for pulmonary oedema. Since the positive effects are not sufficiently documented, and since the risk for increased mortality cannot be ruled out, one can advocate that the use should be avoided.

    PURPOSE Acute thoracic aortic syndrome (ATAS) is a novel term to define emergency aortic conditions with common clinical features and challenges. Traditional management of ATAS includes surgical replacement of the aorta and is correlated with high perioperative mortality and morbidity. We aimed to evaluate our experience and outcomes in patients presenting with ATAS, managed by endovascular techniques. METHODS This cohort consisted of 31 consecutive patients (24 males; mean age, 57.5±13.81 years; range, 19–84 years) with acute thoracic aortic pathologies who underwent endovascular repair between January 2011 and January 2015. The study was designed as a retrospective analysis of prospectively maintained data. RESULTS Complicated acute type-B aortic dissection was the most common pathology (35.5%). All aortic stent-grafts (n=37) and dissection stents (n=9) were implanted with 100% procedural success. The overall in-hospital mortality was 9.7%. The mean follow-up duration of patients who were alive at 30 days was 25.9±11.49 months (3–53 months). So far, there have been no late deaths after 30 days. CONCLUSION In the high-risk setting of ATAS, endovascular procedures come forward as novel therapeutic strategies with promising results. Endovascular repair of ATAS can be considered as a first-line treatment alternative under emergency conditions with encouraging results, particularly when conventional surgical repair cannot be implemented due to prohibitive comorbidities.

    Oritavancin, a semisynthetic derivative of the glycopeptide antibiotic chloroeremomycin, received the US Food and Drug Administration approval for the treatment of acute bacterial skin and skin structure infections caused by susceptible Gram-positive bacteria in adults in August 2014. This novel second-generation semisynthetic lipoglycopeptide antibiotic has activity against a broad spectrum of Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-intermediate S. aureus (VISA), and vancomycin-resistant Enterococcus. Oritavancin inhibits bacterial cell wall synthesis and is rapidly bactericidal against many Gram-positive pathogens. The long half-life of this drug enables a single-dose administration. Oritavancin is not metabolized in the body, and the unchanged drug is slowly excreted by the kidneys. In two large Phase III randomized, double-blind, clinical trials, oritavancin was found to be non-inferior to vancomycin in achieving the primary composite end point in the treatment of acute Gram-positive skin and skin structure infections. Adverse effects noted were mostly mild with nausea, headache, and vomiting being the most common reported side effects. Oritavancin has emerged as another useful antimicrobial agent for treatment of acute Gram-positive skin and skin structure infections, including those caused by MRSA and VISA. PMID:26185459

    The expression of the steroidogenic acute regulatory protein (StAR) in the human corpus luteum (CL) was examined throughout the luteal phase. The primary 1.6-kb StAR transcript was in greater abundance in early (3.1-fold) and mid (2.2-fold) luteal phase CL compared with late luteal phase CL. The larger StAR transcript (4.4 kb) was found in early and midluteal phase CL, but was not detected in late luteal phase specimens. Mature StAR protein (30 kDa) was present in lower amounts within late CL compared with early and midluteal phase CL. The StAR preprotein (37 kDa) was also detected in greater abundance in early and midluteal CL. Immunohistochemistry revealed that StAR staining was most prominent in thecal-lutein cells throughout the luteal phase. The intensity of the signal for StAR exhibited significant changes throughout the luteal phase, being most intense during the midluteal phase and least during the late luteal phase. Plasma progesterone concentrations were highly correlated (r = 0.73 and r = 0.79) with luteal expression of the preprotein and mature StAR isoforms, respectively, throughout the luteal phase. To examine the LH dependency of StAR expression, the GnRH antagonist, Cetrorelix, was administered during the midluteal phase. Cetrorelix caused a decline in serum LH levels within 2 h, which, in turn, caused a pronounced decline in plasma progesterone within 6 h. The StAR 4.4-kb transcript was not detectable, and the 1.6-kb transcript was reduced by approximately 50% within 24 h of Cetrorelix treatment. The mature 30-kDa StAR protein level declined approximately 30% after Cetrorelix treatment. We conclude that 1) StAR mRNA and protein are highly expressed in early and midluteal phase CL; 2) StAR protein is present in both thecal-lutein and granulosa-lutein cells throughout the luteal phase; 3) StAR protein levels in the CL are highly correlated with plasma progesterone levels; 4) declining StAR mRNA and protein levels are characteristic of late luteal

    The Severe Acute Pancreatic Unit of Edgardo Rebagliati Martins National Hospital was officially created in the year 2000. Up to date, we have cared for more than 195 patients with Pancreatic Necrosis. All of them have been treated under a management protocol presented by us. This has helped us to standardize treatment and also to compare results with work groups around the world. This Protocol comes from our own experience and that of our colleagues abroad with a wide knowledge in this kind of pathology abroad, with whom we maintain close ties.

  9. Diagnosis and treatment of acute low back pain.

    Casazza, Brian A

    2012-02-15

    Acute low back pain is one of the most common reasons for adults to see a family physician. Although most patients recover quickly with minimal treatment, proper evaluation is imperative to identify rare cases of serious underlying pathology. Certain red flags should prompt aggressive treatment or referral to a spine specialist, whereas others are less concerning. Serious red flags include significant trauma related to age (i.e., injury related to a fall from a height or motor vehicle crash in a young patient, or from a minor fall or heavy lifting in a patient with osteoporosis or possible osteoporosis), major or progressive motor or sensory deficit, new-onset bowel or bladder incontinence or urinary retention, loss of anal sphincter tone, saddle anesthesia, history of cancer metastatic to bone, and suspected spinal infection. Without clinical signs of serious pathology, diagnostic imaging and laboratory testing often are not required. Although there are numerous treatments for nonspecific acute low back pain, most have little evidence of benefit. Patient education and medications such as nonsteroidal anti-inflammatory drugs, acetaminophen, and muscle relaxants are beneficial. Bed rest should be avoided if possible. Exercises directed by a physical therapist, such as the McKenzie method and spine stabilization exercises, may decrease recurrent pain and need for health care services. Spinal manipulation and chiropractic techniques are no more effective than established medical treatments, and adding them to established treatments does not improve outcomes. No substantial benefit has been shown with oral steroids, acupuncture, massage, traction, lumbar supports, or regular exercise programs. PMID:22335313

    Background Few studies have assessed whether treatment of acute cervical spinal cord injury (SCI) patients contributes to depression. Methods Using an administrative database, we assessed patients for whom the diagnosis was unspecified injuries of cervical spinal cord (International Classification of Diseases and Injuries-10th (ICD-10) code; S14.1). We categorized patients with codes for depressive episode (ICD-10 code; F32) or recurrent depressive disorder (F33), or those prescribed antidepressants (tricyclic, tetracyclic, Selective Serotonin Reuptake Inhibitors, Serotonin Noradrenaline Reuptake Inhibitors, Trazodone, Sulpiride, or Mirtazapine) as having a depressive state. We compared the rate of each acute treatment between the depressive state group and the non-depressive state group using chi-square tests, and a multiple logistic regression model was used to identify the association between the acute treatment and depressive state. Results There were 151 patients who were judged to be in a depressive state, and the other 2115 patients were categorized into the non-depressive state group. Intervention of intravenous anesthesia, tracheostomy, artificial respiration, and gastrostomy had a significant positive correlation with depressive state. Multiple logistic regression analysis showed that tracheostomy (odds ratio [OR] 2.18; 95% confidence interval [CI], 1.09–4.38) and artificial respiration (OR 2.28; 95% CI, 1.32–3.93) were significantly associated with depressive state, and men had a 36% reduction in the risk of depressive state compared with women (OR 0.64; 95% CI, 0.44–0.94), whereas age, wound-treatment, all of the orthopedic procedures, intravenous anesthesia, and gastrostomy were not associated with depressive state. Conclusions These findings suggest that tracheostomy, artificial respiration and female gender in the acute phase after cervical SCI might be associated with the development of depression.

    This article reports the treatment of a patient suffered from acute radiation burn covering 41% TBSA, with deep partial-thickness and full-thickness injury, produced by exposure to a large-scale industrial electron accelerator. An open wound began to appear and enlarged gradually 10 weeks after the exposure. Serious wound infection with methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa, pneumonia, respiratory failure, systemic inflammatory response syndrome, nephropathy and hypoproteinemia developed successively since 3 weeks after the wound formation. Skin grafts failed to survive, resulting in enlargement of the wound. After being treated with proper measures, including parenteral nutrition, respiratory support with a ventilator, appropriate antibiotics, steroid administration for nephropathy, deep debridement for wounds followed by skin grafting, the patient was cured and discharged after undergoing 15 operations in 500 days. The clinical condition of an extensive acute radiation burn is complicated. We should pay close attention to the changes in functions of organs, and strengthen the therapeutic strategies to support the function of organs to reduce the incidence of systemic complications. The control of the infection and the timely and effective repair of the wound are still the key points of the treatment of an extensive local radiation injury.

    First introduced into clinical practice in 1969, glibenclamide (US adopted name, glyburide) is known best for its use in the treatment of diabetes mellitus type 2, where it is used to promote the release of insulin by blocking pancreatic KATP [sulfonylurea receptor 1 (Sur1)-Kir6.2] channels. During the last decade, glibenclamide has received renewed attention due to its pleiotropic protective effects in acute CNS injury. Acting via inhibition of the recently characterized Sur1-Trpm4 channel (formerly, the Sur1-regulated NCCa-ATP channel) and, in some cases, via brain KATP channels, glibenclamide has been shown to be beneficial in several clinically relevant rodent models of ischemic and hemorrhagic stroke, traumatic brain injury, spinal cord injury, neonatal encephalopathy of prematurity, and metastatic brain tumor. Glibenclamide acts on microvessels to reduce edema formation and secondary hemorrhage, it inhibits necrotic cell death, it exerts potent anti-inflammatory effects and it promotes neurogenesis—all via inhibition of Sur1. Two clinical trials, one in TBI and one in stroke, currently are underway. These recent findings, which implicate Sur1 in a number of acute pathological conditions involving the CNS, present new opportunities to use glibenclamide, a well-known, safe pharmaceutical agent, for medical conditions that heretofore had few or no treatment options.

    Monoclonal antibodies have become an important treatment modality in cancer therapy. Genetically engineered chimaeric and humanised antibodies have demonstrated activity against a variety of tumours. Whereas the humanised anti-CD33 monoclonal antibody HuM195 has only modest activity against overt acute myeloid leukaemia (AML), it can eliminate minimal residual disease detectable by reverse transcription-polymerase chain reaction in acute promyelocytic leukaemia. High-dose radioimmunotherapy with beta-particle-emitting isotopes targeting CD33, CD45 and CD66 can potentially allow intensification of antileukaemic therapy before bone marrow transplantation. Conversely, alpha-particle immunotherapy with isotopes such as bismuth-213 or actinium-225 offers the possibility of selective tumour cell kill while sparing surrounding normal cells. Targeted chemotherapy with the anti-CD33-calicheamicin construct gemtuzumab ozogamicin has produced remissions as a single agent in patients with relapsed AML and appears promising when used in combination with standard chemotherapy in the treatment of newly diagnosed AML.

  15. Acute Coronary Syndromes in Women: Recent Treatment Trends and Outcomes.

    PubMed

    2016-01-01

    In the USA and internationally, women experience farranging differences with respect to acute coronary syndrome (ACS) and myocardial infarction (MI). Women suffer from more comorbidities than men, such as smoking, obesity, hypertension, diabetes, and poor mental health. They some-times exhibit atypical MI presentation symptoms and are overall less likely to present with chest pain. Women are more likely than men to encounter delays between the onset of symptoms and arrival at the hospital or to guideline treatment. The use of various surgical and pharmacological treatments, including revascularization approaches, also differs. Women, on average, have worse outcomes than men following MI, with more complications, higher mortality rates, and poorer recovery. Internationally, outcomes are similar despite various differences in health care and culture in non-US countries. In this review, we detail differences regarding ACS and MI in women, describing their complex correlations and discussing their possible causes. Educational approaches that are tailored to women might help to reduce the incidence of ACS and MI, as well as outcomes following hospitalization. Although outcomes following acute MI have been improving over the years, women may require special consideration in order to see continued improvement.

    Migraine is a common disease in children and adolescents. The incidence of migraine has increased alarmingly in the general population during recent decades. Migraine causes considerable individual suffering and impaired quality of life. Therefore, appropriate management is essential. In this article, the treatment of acute migraine in children and adolescents will be reviewed. Only a few randomized controlled studies have been published and high placebo rates are a major problem for proving superiority of active drugs. Generally, acetaminophen (paracetamol) and ibuprofen are accepted as drugs of first choice, even though the evidence is poor for the former and limited for latter. Among 14 studies on triptans in adolescents, 9 showed some superiority over placebo with respect to pain relief and pain freedom, and among 6 studies in children, 5 suggest some superiority over placebo. Sumatriptan nasal spray and zolmitriptan nasal spray have been approved for adolescents in Europe; almotriptan has been approved for adolescents in the USA, as has rizatriptan for patients aged 6-17 years. A recent study demonstrated the efficacy of a fixed combination of sumatriptan and naproxen in adolescents with migraine. In conclusion, evidence for the pharmacological treatment of acute migraine in children is very poor and evidence for adolescents is better but still limited. PMID:23575981

    To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety. PMID:26080572

    A review of the evidence on treatment of acute bronchiolitis is presented. There is sufficient evidence on the lack of effectiveness of most interventions tested in bronchiolitis. Apart from oxygen therapy, fluid therapy, aspiration of secretions and ventilation support, few treatment options will be beneficial. There are doubts about the efficacy of inhaled bronchodilators (salbutamol or adrenaline), with or without hypertonic saline solution, suggesting that these options should be selectively used as therapeutic trials in moderate-severe bronchiolitis. Heliox and non-invasive ventilation techniques, methylxanthine could be used in cases with respiratory failure, in patients with apnea, and surfactant and inhaled ribavirin in intubated critically ill patients. The available evidence does not recommend the use of oral salbutamol, subcutaneous adrenaline, anticholinergic drugs, inhaled or systemic corticosteroids, antibiotics, aerosolized o intravenous immunoglobulin, respiratory physiotherapy and others (nitric oxide, recombinant human deoxyribonuclease, recombinant interferon, nebulised furosemide and so on).

    We present an interesting case of salicylism arising from the use of methyl salicylate as part of a herbal skin cream for the treatment of psoriasis. A 40-year-old man became quite suddenly and acutely unwell after receiving treatment from an unregistered naturopath. Methyl salicylate (Oil of Wintergreen) is widely available in many over the counter topical analgesic preparations and Chinese medicated oils. Transcutaneous absorption of the methyl salicylate was enhanced in this case due to the abnormal areas of skin and use of an occlusive dressing. The presence of tinnitus, vomiting, tachypnoea and typical acid/base disturbance allowed a diagnosis of salicylate toxicity to be made. Our patient had decontaminated his skin prior to presentation, limiting the extent of toxicity and was successfully treated with rehydration and establishment of good urine flow.

    The molecular analysis of acute lymphoblastic leukemia (ALL) has provided exciting insights into the pathogenesis of this disease. This disease is heterogenous and can be subtyped based on chromosomal, immunophenotypic, and structural criteria. The varying prognostic implications of different ALL subtypes markedly influence the treatment decisions in adults. Many patients with T-cell ALL can be cured with chemotherapy alone. In contrast, patients with early B-lineage ALL with certain chromosomal abnormalities, especially the Philadelphia chromosome, do not have durable responses to chemotherapy and should receive a bone marrow transplantation if an HLA-matched donor is available. Recent reports have shown improved results for adults with B-cell ALL (Burkitt's) after intensive alternating cycles of chemotherapy containing high doses of methotrexate and cyclophosphamide. Future clinical and laboratory investigation should lead to the development of novel and possibly more effective treatments specifically tailored for different subsets of ALL. PMID:8775728

    Although survival rates for acute lymphocytic leukemia (ALL), especially in children, have shown dramatic improvement over time, poor outcomes are still observed in patients who have refractory or relapsed disease after conventional chemotherapy. New therapeutic options are urgently needed. Bortezomib (Velcade, formerly PS-341) is the first proteasome inhibitor approved by the US FDA for the treatment of newly diagnosed multiple myeloma and relapsed/refractory multiple myeloma and mantle cell lymphoma. Although the mechanisms of bortezomib anticancer activity are still not completely understood, it is a new treatment option for patients with refractory or relapsed ALL, particularly when used in combination with conventional chemotherapy or targeted agents. This review summarizes recent advancements in the understanding of the bortezomib molecular mechanism of action in ALL. Understanding of the molecular approaches might help customize cancer chemotherapy for each individual patient, directing the field towards rational therapeutics.

    2007-04-01

    Acute otitis media (AOM) is both a commonly diagnosed condition and a frequent indication for antibiotic use in children. Recent literature suggests that antibiotics are not needed in many children with AOM, as most cases resolve spontaneously without complication. However, a majority of AOM infections in children are still treated with antibiotics. The American Academy of Pediatrics and American Academy of Family Physicians released a guideline for treatment of AOM in children. We review the guideline as well as scientific evidence related to AOM treatment options. We support a set of evidence-based guidelines employing a delayed prescription option for antibiotic therapy in selected children. If used appropriately, these cost-effective guidelines will reduce the amount of antibiotics prescribed, increase parental satisfaction, and may lower rates of antibiotic resistance while producing similar rates of resolution of AOM.

    Children aged 0–2 years (i.e., infants) with acute myeloid leukemia (AML) are a peculiar subgroup of patients in the childhood AML scenario. They present with distinctive biological and clinical characteristics, including a high prevalence of prognostically unfavorable risk factors and an increased susceptibility to therapy-related toxicity. Remarkable improvements have been achieved over the last two decades in the treatment of these patients and their outcome is becoming superimposable to that of the older age groups. In this review, we will focus on peculiarities of this young subgroup of children with AML, describing their clinical presentation, the biology of disease, and factors influencing outcome. Treatment results and toxicity data reported by major collaborative groups are also summarized and compared. PMID:25973412

    Ethionine administered intraperitoneally to rats suffering from turpentine-induced inflammation preferentially reduced incorporation of 14C-leucine into fibrinogen, haptoglobin and other acute-phase proteins. The inhibitory effect was observed both in vivo and in liver slices obtained from ethionine-treated donors, while addition of ethionine to liver slices in vitro led to general reduction of synthesis of all liver and plasma proteins, including albumin. For comparison, the effects of galactosamine and actinomycin D on plasma protein synthesis in injured rats were also examined. It has been concluded that ethionine acts in the early phases of the acute-phase response, probably by inhibition of trauma-induced transcription of liver mRNA specific for acute-phase proteins.

    This is an exciting time in the treatment of acute lymphoblastic leukemia (ALL) given the advances in the relapsed/refractory setting. The development of antibody treatments (including antibody drug conjugates with toxins) offers a different treatment approach compared with conventional chemotherapy regimens. Moreover, the use of bispecific T-cell-engager antibodies (BiTEs) such as blinatumomab harness the cytotoxic activity of T cells against CD19-positive lymphoblasts. Another strategy involves the use of chimeric antigen receptor (CAR) T cells. CAR T cells have demonstrated promising results in the relapsed/refractory setting. However, the use of BiTEs and CAR T cells is also associated with a distinct set of adverse reactions that must be taken into account by the treating physician. Apart from the above strategies, the use of other targeted therapies has attracted interest. Namely, the discovery of the Philadelphia (Ph)-like signature in children and young adults with ALL has led to the use of tyrosine kinase inhibitors (TKI) in these patients. The different drugs and strategies that are being tested in the relapsed/refractory ALL setting pose a unique challenge in identifying the optimum sequence of treatment and determining which approaches should be considered for frontline treatment.

    Background We conducted a clinical trial to test whether prophylactic cranial irradiation could be omitted in all children with newly diagnosed acute lymphoblastic leukemia. Methods A total of 498 evaluable patients were enrolled. Treatment intensity was based on presenting features and the level of minimal residual disease after remission induction treatment. Continuous complete remission was compared between the 71 patients who previously would have received prophylactic cranial irradiation and the 56 historical controls who received it. Results The 5-year event-free and overall survival probabilities (95% confidence interval) for all 498 patients were 85.6% (79.9% to 91.3%) and 93.5% (89.8% to 97.2%), respectively. The 5-year cumulative risk of isolated central-nervous-system (CNS) relapse was 2.7% (1.1% to 4.2%), and that of any CNS relapse (isolated plus combined) was 3.9% (1.9% to 5.9%). The 71 patients had significantly better continuous complete remission than the 56 historical controls (P=0.04). All 11 patients with isolated CNS relapse remain in second remission for 0.4 to 5.5 years. CNS leukemia (CNS-3 status) or a traumatic lumbar puncture with blasts at diagnosis and a high level of minimal residual disease (≥ 1%) after 6 weeks of remission induction were significantly associated with poorer event-free survival. Risk factors for CNS relapse included the presence of the t(1;19)[TCF3-PBX1], any CNS involvement at diagnosis, and T-cell immunophenotype. Common adverse effects included allergic reactions to L-asparaginase, osteonecrosis, thrombosis, and disseminated fungal infection. Conclusions With effective risk-adjusted chemotherapy, prophylactic cranial irradiation can be safely omitted in the treatment of childhood acute lymphoblastic leukemia. PMID:19553647

    Peripheral neuropathy is a common complication of arsenic toxicity. Symptoms are usually mild and reversible following discontinuation of treatment. A more severe chronic sensorimotor polyneuropathy characterized by distal axonal-loss neuropathy can be seen in chronic arsenic exposure. The clinical course of arsenic neurotoxicity in patients with coexistence of thiamine deficiency is only anecdotally known but this association may potentially lead to severe consequences. We describe a case of acute irreversible axonal neuropathy in a patient with hidden thiamine deficiency who was treated with a short course of arsenic trioxide for acute promyelocytic leukemia. Thiamine replacement therapy and arsenic trioxide discontinuation were not followed by neurological recovery and severe polyneuropathy persisted at 12-month follow-up. Thiamine plasma levels should be measured in patients who are candidate to arsenic trioxide therapy. Prophylactic administration of vitamin B1 may be advisable. The appearance of polyneuropathy signs early during the administration of arsenic trioxide should prompt electrodiagnostic testing to rule out a pattern of axonal neuropathy which would need immediate discontinuation of arsenic trioxide.

We prefer the method used by Brunner, but under general anaesthesia and using a Bentley-Autotransfusion-System (ATS). The average age of our patients was 55 years (age ranged between 17 and 87 years). No lethal pulmonary embolism was observed. 2, 1 percent of the patients died following apoplex or acute heart failure. Of 67 patients who were operated on 6 months ago or more 70 percent have no further complaints, 28 percent still have some residual edema and only 2 patients have a severe postthrombotic syndrome. 50 percent of 40 control-phlebograms demonstrated patency of all veins. 20 percent had short segmentary occlusions with definite signs of recanalisation, while in 27 percent of the cases occlusions of the lower leg and thigh were found, the iliac veins being free. Only 2 postoperative phlebograms showed a complete iliofemoral venous occlusion. Our results prove, that the operative thrombectomy is a successful method, with which the main complications of the iliofemoral thrombosis-pulmonary embolisation and postthrombotic syndrome-can difinitely be reduced. Also because of better long term results, the operative therapy of acute ilofemoral thrombosis should be generally prefered instead of conservative treatment.

Diagnosis is usually based on abdominal pain and elevation of serum lipase to more than three-times the normal limit. Acute pancreatitis can either resolve quickly following an oedematous swelling or present as a severe necrotizing form. A major risk is the systemic inflammatory response syndrome (SIRS), which can cause multi-organ failure. Prediction of disease course is initially difficult, thus necessitating immediate therapy and regular re-evaluation. In order to prove or exclude biliary genesis, abdominal ultrasonography should first be performed and endoscopic ultrasound may also be required. Primary therapy includes rapid and correctly dosed fluid substitution. Biliary pancreatitis requires causal treatment. In the case of cholangitis, stone extraction must be performed immediately; in the absence of cholangitis, it might be advisable to wait for spontaneous stone clearance. Timely cholecystectomy is necessary in all cases of biliary pancreatitis. PMID:25139706

    The pathophysiological basis of sudden cardiac death due to ventricular arrhythmias in acute myocardial infarction has been extensively investigated in experimental as well as in some clinical studies. Numerous clinical studies have been performed with the aim to establish the feasibility of antifibrillatory prophylaxis of sudden cardiac death by pretreatment with antiarrhythmic drugs. Using class I-antiarrhythmic drugs the reported findings were contradictory. While the antiarrhythmic efficacy of Lidocaine and other, newer class I-antiarrhythmic drugs is well established, the antifibrillatory effects of these drugs in the early phase of acute myocardial infarction remain uncertain. In clinical studies with the endpoint of mortality in patients at risk, longterm administration of orally effective class I-antiarrhythmic drugs did not prove to be superior to placebo. However, beta-sympatholytic agents have been shown to reduce mortality in patients at risk in several large clinical studies. The basic mechanism seems to be primarily a reduction in sudden cardiac death which is caused predominantly by ventricular fibrillation. The antifibrillatory properties of beta-blockers was demonstrated as well by a reduction in the number of episodes of ventricular fibrillation. The recognition of patients at risk who profit most from chronic beta-blocker therapy remains the main problem when treatment of numerous low-risk patients is avoided. In the ISIS I-study with Atenolol intravenous administration of a beta-blocker in the early phase of acute myocardial infarction has been shown to be beneficial if hemodynamic monitoring, for example using flow-directed heart catherization is performed. In general this does not apply to the treatment with calciumantagonists, especially with Verapamil and Nifedipine. These drugs do not improve prognosis of acute myocardial ischemia, obviously because of hemodynamic side effects. The antifibrillatory efficacy of Verapamil

    Acute phase changes in trace mineral metabolism were examined in turkey embryos. An endotoxin injection resulted in increased concentrations of serum copper and liver zinc and decreased concentrations of serum zinc in embryos incubated either in ovo or ex ovo. Changes in zinc and copper metabolism occurred when endotoxin either was injected intramuscularly, into the amnionic fluid, or administered onto the chorioallantoic membrane. Unlike poults, embryos did not respond to an inflammatory challenge with decreased serum iron concentrations. Acute phase changes in embryo serum zinc and copper as well as liver zinc concentrations were similar to those in poults. Increased liver zinc concentrations were associated with increased zinc in metallothionein (MT). An injection of a crude interleukin 1 preparation into embryos resulted in similar increases in hepatic zinc and MT concentrations as an endotoxin injection, suggesting a role for this cytokine in mediating the acute phase changes in embryonic zinc metabolism.

    Background There has been a focus recently on the use of the Internet and email to deliver education interventions to general practitioners (GPs). The treatment of breast cancer may include surgery, radiotherapy, chemotherapy, and/or hormone treatment. These treatments may have acute adverse effects. GPs need more information on the diagnosis and management of specific adverse effects encountered immediately after cancer treatment. Objective The goal was to evaluate an Internet-based educational program developed for GPs to advise patients with acute adverse effects following breast cancer treatment. Methods During phase 1, participants viewed 6 video vignettes of actor-patients reporting 1 of 6 acute symptoms following surgery and chemotherapy and/or radiotherapy treatment. GPs indicated their diagnosis and proposed management through an online survey program. They received feedback about each scenario in the form of a specialist clinic letter, as if the patient had been seen at a specialist clinic after they had attended the GP. This letter incorporated extracts from local guidelines on the management of the symptoms presented. This feedback was sent to the GPs electronically on the same survey platform. In phase 2, all GPs were invited to manage similar cases as phase 1. Their proposed management was compared to the guidelines. McNemar test was used to compare data from phases 1 and 2, and logistic regression was used to explore the GP characteristics that were associated with inappropriate case management. Results A total of 50 GPs participated. Participants were younger and more likely to be female than other GPs in Australia. For 5 of 6 vignettes in phase 1, management was consistent with expert opinion in the minority of cases (6%-46%). Participant demographic characteristics had a variable effect on different management decisions in phase 1. The variables modeled explained 15%-28% of the differences observed. Diagnosis and management improved significantly

    To determine the acute immunologic reaction, mediated by cytokines, interleukines (ILs) and growth factors and the susceptibility to infections and sepsis after severe burn injury a prospective, single unit, longitudinal study of acute phase reactants and mediators who performed. After approval by the ethics committee of our hospital, we investigated the plasma concentrations of IL-2, -6, -8, -10, and -13, the soluble IL-2 receptor (sIL-2R), and the acute phase proteins procalcitonin (PCT) and C-reactive protein (CRP) at admission and every 3 days in 24 patients over a time course of 28 days after thermal injury and categorized by percent burn: < or =30% (group 1; n=12) and >30% (group 2; n=12). Shortly after burn injury we found higher concentrations of IL-2, -6, -10 and PCT in those patients >30% TBSA. During the study period, we found significant higher levels of acute phase proteins, IL-6 and -8 in patients >30% TBSA. The incidence of SIRS and MODS was three times increased in patients >30% TBSA. Our results show different patterns of cytokines and acute phase proteins in patients with different burned surface areas over a long time and continuous monitoring of a more distinct inflammatory response in these patients.

    Systemic inflammatory reactions are a prominent feature of many parasitic infections and the cellular and humoral components of the acute phase reaction may have an impact on the host-parasite relationship. We examined serum changes of four acute phase reactants: alpha 1-proteinase inhibition (alpha 1Pi); complement C3; serum amyloid A protein (SAA); and serum amyloid P component (SAP), in mice undergoing a primary infection with Nippostrongylus brasiliensis. SAA and SAP showed changes within the first 2 days of infection indicating the presence of an acute phase response associated with inflammation in the lung. Alpha 1Pi and C3 serum levels were not altered. However, all four acute phase reactants were synthesized in greater amounts by primary cultures of hepatocytes taken from infected animals at this time. Subsequently, as parasite-mediated inflammatory changes occur in the gut, both serum and hepatocyte cultures demonstrate an acute inflammatory response in all four reactants. It is proposed that the early reaction between parasites and macrophage/monocyte lead to the release of a mediator of inflammation which initiates the hepatocyte response. In this infection, at least one of the APR is shown to localize to the site of inflammation influencing the host-parasite relationship. Images Figure 2 Figure 3 PMID:6204934

    Acute otitis media (AOM) is a common condition in children that is often treated with systemic antibiotic therapy; however, research suggests that non-complicated AOM will resolve spontaneously using only eardrops. To determine best practice for the use of systematic antibiotics compared to topical treatment of AOM, a systematic review of evidence was conducted. Cochrane, Medline, CINAHL, and other databases were searched. Inclusion criteria were studies published from 1995-2010 that included children with AOM and were randomized controlled trials (RCTs). Five systematic reviews and five RCTs were included in the review. Current evidence recommends using topical and other alternative approaches for treating non-complicated AOM in children 2 years of age or older; however, many practitioners are not currently following these recommendations for various reasons. Additional research to address these reasons may help determine how to improve practitioner adherence to best practice evidence and guidelines to help reduce the unnecessary use of systemic antibiotics.

    Antibiotic treatment of acute otitis media (AOM) accounts for a significant number of all antibiotic prescriptions each year. In the primary care setting, initial antibiotic selection is rarely based on direct evidence, such as cultures of middle ear fluid. Initial antibiotic therapy by the primary care practitioner involves the evaluation and application of information related to prevalence of infecting organisms; in vitro antibiotic spectrum and penetration into middle ear fluid; initial cure rate, relapse and recurrence rates; and antibiotic cost, safety, and convenience. The influence of these factors on the initial antibiotic choice for AOM is reviewed. Several therapeutic dilemmas confronting the prescriber are discussed and a rational approach to initial antibiotic therapy is presented.

    Generalised acute peritonitis is a relatively frequently pathology which has always been extremely difficult to treat owing to the large number of complications. Considerable progress has been made over the past few years in the surgical treatment of these pathologies following the introduction of new materials accompanied by new techniques: continuous peritoneal lavage (CPL) and laparostomy are the best known. These techniques must be used in carefully selected patients. They allow a marked improvement in results: fewer cases of redo surgery; fewer local and general complications; shorter hospitalisation stay; fewer deaths. These results are possible because these techniques ensure a better cleansing of the peritoneal cavity, with easier removal of necrotic and purulent materials, the main cause of local and general complications.

    The objective of this study was to determine the effects of investigational vaccine candidates on acute-phase proteins (APPs) as determined in GLP toxicology studies. Sixty-four GLP toxicity studies, which were submitted to the Food and Drug Administration from 2008 to 2012 in support of proposed clinical investigations, were reviewed and entered into a database. These studies employed the intramuscular route of injection and were conducted using New Zealand White rabbits. A retrospective review of these GLP toxicity studies was conducted to evaluate the changes in plasma levels of C-reactive protein (CRP), fibrinogen, and albumin as APPs following the administration of various investigational vaccines. The incidence and intensity of responses associated with acute-phase responses both positive and negative were observed to increase in animals when treated with vaccines containing more potent immunological components such as novel adjuvants that activate Toll-like receptors in the investigational vaccine products. Changes in plasma levels of CRP were prominent among these responses and provided a basis to propose a classification scheme of H, M, L, and N responding groups. These changes in plasma proteins reflect an activation of the acute-phase response and indicate increasing levels of systemic inflammation, which potentially may be correlated with important clinical adverse events.

    While progress has been made in improving survival following myocardial infarction, this injury remains a major source of mortality and morbidity despite modern reperfusion therapy. While one approach has been to develop therapies to reduce lethal myocardial cell reperfusion injury, this concept has not translated to the clinics, and several recent negative clinical trials raise the question of whether reperfusion injury is important in humans undergoing reperfusion for acute ST segment elevation myocardial infarction. Therapy aimed at reducing myocardial cell death while the myocytes are still ischemic is more likely to further reduce myocardial infarct size. Developing new therapies to further reduce left ventricular remodeling after the acute event is another approach to preserving structure and function of the heart after infarction. Such therapy may include chronic administration of pharmacologic agents and/or therapies developed from the field of regenerative cardiology, including cellular or non-cellular materials such as extracellular matrix. The optimal therapy will be to administer agents that both reduce myocardial infarct size in the acute phase of infarction as well as reduce adverse left ventricular remodeling during the chronic or healing phase of myocardial infarction. Such a dual approach will help optimize the preservation of both cardiac structure and function.

    The adrenal cortex has a molecular clock that generates circadian rhythms in glucocorticoid production, yet it is unclear how the clock responds to acute stress. We hypothesized that stress-induced ACTH provides a signal that phase shifts the adrenal clock. To assess whether acute stress phase shifts the adrenal clock in vivo in a phase-dependent manner, mPER2:LUC mice on a 12:12-h light:dark cycle underwent restraint stress for 15 min or no stress at zeitgeber time (ZT) 2 (early subjective day) or at ZT16 (early subjective night). Adrenal explants from mice stressed at ZT2 showed mPER2:LUC rhythms that were phase-advanced by ~2 h, whereas adrenals from mice stressed at ZT16 showed rhythms that were phase-delayed by ~2 h. The biphasic response was also observed in mice injected subcutaneously either with saline or with ACTH at ZT2 or ZT16. Blockade of the ACTH response with the glucocorticoid, dexamethasone, prevented restraint stress-induced phase shifts in the mPER2:LUC rhythm both at ZT2 and at ZT16. The finding that acute stress results in a phase-dependent shift in the adrenal mPER2:LUC rhythm that can be blocked by dexamethasone indicates that stress-induced effectors, including ACTH, act to phase shift the adrenal clock rhythm.

    High-risk acute myelogenous leukemia (AML) constitutes a distinct subset of disease based on clinical and biological characteristics and comprises a significant percentage of all cases of adult AML. Biologic features such as distinct clonal cytogenetic and molecular abnormalities identify a subgroup of AML patients characterized by poor response to induction chemotherapy and poor long-term survival after treatment with consolidation chemotherapy. Clinical variables that predict for poor response include AML relapsed after less than 1 year of remission and AML characterized by resistance to conventional agents. We review here our understanding of the defining biologic subtypes of AML and discuss how adequate initial evaluation can be used to inform the choice of treatment. By defining high-risk biologic and clinical variables, a strong case can be made for treating patients with investigational agents, with treatment directed at distinct cytogenetic or molecular abnormalities. Allogeneic transplantation is the only form of therapy available outside of the setting of a clinical trial that may offer a chance for long-term survival for patients with high-risk AML.

    Due to the ground breaking consistent evidence that supports the effect of endovascular stroke treatment (EST), many acute care hospitals and stroke centers will have to be prepared to provide this treatment in an optimal way within the coming years. In addition to the intervention itself, patient preparation, stabilization and monitoring during the treatment as well as the aftercare represent significant challenges and have mostly not yet been sufficiently investigated. Under these aspects, the questions of optimal sedation and airway management have received the highest attention. Based on retrospective study results it already seems to be justified, respecting certain criteria, to prefer EST with the patient under conscious sedation (CS) in comparison to general anesthesia (GA) and to only switch to GA in cases of emergency until this question has been clarified by prospective studies. This and other aspects of peri-interventional management, such as logistics, monitoring, blood pressure, ventilation settings, postprocedural steps of intensive or stroke unit care and imaging follow-up are summarized in this overview. The clinical and radiological selection of patients and thus the decision for intervention or technical aspects of the intervention itself will not be part of this article. PMID:26311331

    To evaluate the efficacy of intracranial pressure (ICP)-targeted treatment, compared to standard intensive care, in adults with community acquired acute bacterial meningitis (ABM) and severely impaired consciousness, a prospectively designed intervention-control comparison study was performed. Included were patients with confirmed ABM and severely impaired mental status on admission. Fifty-two patients, given ICP-targeted treatment at a neuro-intensive care unit, and 53 control cases, treated with conventional intensive care, were included. All patients received intensive care with me-chanical ventilation, sedation, antibiotics and corticosteroids according to current guidelines. ICP-targeted treatment was performed in the intervention group, aiming at ICP 50 mmHg. The mortality was significantly lower in the intervention group compared to controls, 5/52 (10%) versus 16/53 (30%). Furthermore, only 17 patients (32%) in the control group fully recovered, compared to 28 (54%) in the intervention group. Early neuro-intensive care using ICP-targeted therapy reduces mortality and improves the overall outcome in adult patients with ABM and severely impaired mental status on admission.

    Distemper disease is an infectious disease reported in several species of domestic and wild carnivores. The high mortality rate of animals infected with canine distemper virus (CDV) treated with currently available therapies has driven the study of new efficacious treatments. Mesenchymal stem cell (MSC)-based therapy is a promising therapeutic option for many degenerative, hereditary, and inflammatory diseases. Therefore, the aim of this study was to characterize stem cells derived from the canine fetal olfactory epithelium and to assess the systemic response of animals infected with CDV to symptomatic therapy and treatment with MSCs. Eight domestic mongrel dogs (N = 8) were divided into two groups: support group (SG) (N = 5) and support group + cell therapy (SGCT) (N = 3), which were monitored over 15 days. Blood samples were collected on days 0, 6, 9, 12, and 15 to assess blood count and serum biochemistry (urea, creatinine, alanine transferase, alkaline phosphatase, gamma-glutamyl transferase, total protein, albumin, and globulin), and urine samples were obtained on days 0 and 15 for urinary evaluation (urine I). The results showed a high mortality rate (SG = 4 and SGCT = 2), providing inadequate data on the clinical course of CDV infection. MSC therapy resulted in no significant improvement when administered during the acute phase of canine distemper disease, and a prevalence of animals with high mortality rate was found in both groups due to the severity of symptoms.

    Hyperbaric oxygen (HBO2) therapy is approved by the FDA for limited clinical indications but is reported to produce pain relief in several chronic pain conditions. However, there have been no studies to explain this apparent analgesic effect of HBO2. Research conducted in our laboratory demonstrates that four daily 60-min HBO2 treatments at 3.5 ATA induced an unparalleled antinociceptive response that consists of 1) an early phase that lasted at least six hours after the HBO2 treatment before dissipating; and 2) a late phase that emerged about 18 hours after the early phase and lasted for up to three weeks. The early phase was sensitive to antagonism by acutely intracerebroventricular (i.c.v.)-administered opioid antagonist naltrexone and the nitric oxide synthase (NOS)-inhibitor L-NAME. The late phase was inhibited by treatment with i.c.v. naltrexone or L-NAME during the four HBO2 treatments but was not antagonized by either naltrexone or L-NAME following acute pretreatment two weeks after HBO2 treatment. These experimental results implicate a novel mechanism that is activated by HBO2, resulting in an antinociceptive response of unusually long duration that is of potential interest in the clinical management of pain. Perspective Hyperbaric oxygen treatment of mice can induce a two-phase antinociceptive response of unusually long duration. Nitric oxide and opioid receptors appear to initiate or mediate both phases of the antinociceptive response. Further elucidation of the underlying mechanism may potentially identify molecular targets that cause long-lasting activation of endogenous analgesic systems. PMID:20418186

    Purpose: Considerable interobserver variability exists among providers and between providers and patients when measuring subjective symptoms. In the recently published Phase III N06C4 trial of mometasone cream vs. placebo to prevent radiation dermatitis, the primary provider-assessed (PA) endpoint, using the Common Toxicity Criteria for Adverse Events (CTCAE), was negative. However, prospectively planned secondary analyses of patient-reported outcomes (PROs), using the Skindex-16 and Skin Toxicity Assessment Tool (STAT), were positive. This study assesses the relationship between PA outcomes and PROs. Methods and Materials: Pearson correlation coefficients were calculated to compare the three tools. Statistical correlations were defined as follows: <0.5, mild; 0.5-0.7, moderate; and >0.7, strong. Results: CTCAE dermatitis moderately correlated with STAT erythema, and CTCAE pruritus strongly correlated with STAT itching. CTCAE pruritus had a moderate correlation with Skindex-16 itching. Comparing the 2 PRO tools, Skindex-16 itching correlated moderately with STAT itching. Skindex-16 burning, hurting, irritation, and persistence all showed the strongest correlation with STAT burning; they showed moderate correlations with STAT itching and tenderness. Conclusions: The PRO Skindex-16 correlated well with the PRO portions of STAT, but neither tool correlated well with CTCAE. PROs delineated a wider spectrum of toxicity than PA measures and provided more information on rash, redness, pruritus, and annoyance measures compared with CTCAE findings of rash and pruritus. PROs may provide a more complete measure of patient experience than single-symptom, PA endpoints in clinical trials assessing radiation skin toxicity.

    Effective antagonism of the P2Y12 platelet receptor is central to the treatment of acute coronary syndrome (ACS) patients, especially in the setting of percutaneous coronary intervention and stenting. According to consensus guidelines, early revascularization and intensive antiplatelet therapy are key to reducing the complications that arise from myocardial ischaemia and the recurrence of cardiovascular events. Until recently, clopidogrel was the key P2Y12 antagonist advocated, but due to several limitations as an antiplatelet agent, newer drugs with more predictable, rapid and potent effects have been developed. Prasugrel and ticagrelor are now the recommended first-line agents in patients presenting with non-ST-segment elevation ACS and ST-segment elevation ACS, due to large-scale randomized trials that demonstrated net clinical benefit of these agents over clopidogrel, as stated in the European guidelines. Although no study has directly compared the two agents, analysis of the data to date suggests that certain patient types, such as diabetics, those with ST-segment elevation myocardial infarction or renal failure and the elderly may have a better outcome with one agent over the other. Further studies are needed to confirm these differences and answer pending questions regarding the use of these drugs to optimize efficacy while minimizing adverse events, such as bleeding. The aim of this review is to provide an overview of the current P2Y12 receptor antagonists in the treatment of ACS, with a focus on issues of appropriate agent selection, timing of treatment, bleeding risk and the future role of personalized treatment using platelet function and genetic testing.

    The "Acute Treatment of Migraine in Adults: The American Headache Society Evidence Assessment of Migraine Pharmacotherapies" provides levels of evidence for medication efficacy for acute treatment of migraine. The goal of this companion paper is to provide guidance on how to choose between evidence-based treatment options, and, based on the clinical characteristics of the patient and their migraine attacks, to provide guidance on designing an individualized strategy for managing migraine attacks. The acute pharmacological treatments described in the American Headache Society evidence assessment can be divided into those initially taken by the patient during the headache phase of the migraine attack, those taken by the patient later in the attack when initial treatments fail, and those administered intravenously or intramuscularly in urgent care settings. Medications taken initially by patients in the headache phase include nonspecific analgesics such as acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs), triptans, and dihydroergotamine (DHE). A stratified approach to treatment is advised, with the choice of medication based on the patient's treatment needs, taking into consideration the attack severity, presence of associated symptoms such as nausea and vomiting, and the degree of migraine-related disability. Individuals with migraine may find reassurance in having a "back-up plan" in the event of an initial acute treatment failure. For those individuals who had a partial response to the initial acute treatment, a second dose might be indicated. When the initial treatment does not provide meaningful and sustained benefits, a treatment from a different medication class is typically chosen. Depending upon the initial treatment used, this might include NSAIDs, triptans, or DHE. Opioids or acetaminophen in combination with codeine or tramadol can be considered as part of the "back-up plan," provided they are used infrequently. When all patient administered

    Population-based data on more than 1 million patients registered in the Surveillance, Epidemiology, and End-Results Program of the National Cancer Institute, 1973-1984, were analyzed to determine the survival of patients with de novo acute nonlymphocytic leukemia (ANLL) and following a first primary tumor treated (with chemotherapy and/or radiation therapy) or untreated. Cases that occurred within 12 months of the first malignant neoplasm were excluded. Survival was estimated using Cox proportional-hazards modeling, with age, sex, and specific type of ANLL as covariates. The 6,271 patients with de novo ANLL had an estimated 12-month survival of 30%, while the 107 patients with treatment-related ANLL had an estimated 12-month survival of 10%. The authors conclude that ANLL that occurs after chemotherapy or radiation therapy is biologically more aggressive and/or resistant to therapy than spontaneous ANLL. This provides a rationale for current studies on treatment-induced cellular changes and on more aggressive therapy for these patients.

    Purpose Investigate antileukemic activity of artemisinins, artesunate (ART), and dihydroartemisinin (DHA), in combination with cytarabine, a key component of acute myeloid leukemia (AML) chemotherapy using in vitro and in vivo models. Methods Using ten human AML cell lines, we conducted a high-throughput screen to identify antimalarial agents with antileukemic activity. We evaluated effects of ART and DHA on cell viability, cytotoxicity, apoptosis, lysosomal integrity, and combination effects with cytarabine in cell lines and primary patient blasts. In vivo pharmacokinetic studies and efficacy of single-agent ART or combination with cytarabine were evaluated in three xenograft models. Results ART and DHA had the most potent activity in a panel of AML cell lines, with selectivity toward samples harboring MLL rearrangements and FLT3-ITD mutations. Combination of ART or DHA was synergistic with cytarabine. Single-dose ART (120 mg/kg) produced human equivalent exposures, but multiple dose daily administration required for in vivo efficacy was not tolerated. Combination treatment produced initial regression, but did not prolong survival in vivo. Conclusions The pharmacology of artemisinins is problematic and should be considered in designing AML treatment strategies with currently available agents. Artemisinins with improved pharmacokinetic properties may offer therapeutic benefit in combination with conventional therapeutic strategies in AML. PMID:27125973

  2. Evaluation and treatment of acute low back pain.

    Acute low back pain with or without sciatica usually is self-limited and has no serious underlying pathology. For most patients, reassurance, pain medications, and advice to stay active are sufficient. A more thorough evaluation is required in selected patients with "red flag" findings associated with an increased risk of cauda equina syndrome, cancer, infection, or fracture. These patients also require closer follow-up and, in some cases, urgent referral to a surgeon. In patients with nonspecific mechanical low back pain, imaging can be delayed for at least four to six weeks, which usually allows the pain to improve. There is good evidence for the effectiveness of acetaminophen, nonsteroidal anti-inflammatory drugs, skeletal muscle relaxants, heat therapy, physical therapy, and advice to stay active. Spinal manipulative therapy may provide short-term benefits compared with sham therapy but not when compared with conventional treatments. Evidence for the benefit of acupuncture is conflicting, with higher-quality trials showing no benefit. Patient education should focus on the natural history of the back pain, its overall good prognosis, and recommendations for effective treatments. PMID:17477101

    The intestinal immune dysfunction due to loss of mucosal and peripheral CD4(+) T cells in individuals with HIV/AIDS is presumably responsible for the establishment of persistent cryptosporidiosis. Simian immunodeficiency virus (SIV)-infected macaques were used to investigate the phase/timing in SIV infection, which permits a self-limiting Cryptosporidium parvum infection to become persistent in immunodeficient hosts because of significant mucosal immune defects. Two groups of SIV-infected macaques were challenged with C. parvum; one was challenged during the acute SIV infection phase (2 weeks post-SIV infection) and the second was challenged during the chronic SIV phase (CD4 counts 200-500 cells/μl of blood). Samples (fecal, blood, biopsy, and necropsy) were collected at different time points after infection to correlate the progression of disease with the immune status of the animals. All seven SIV-infected macaques challenged during the acute phase of SIV infection became persistently infected and excreted oocysts for 1-4 months. However, four of the six in the chronic SIV phase became infected with cryptosporidiosis, of which one survived 2 weeks and one became naturally infected. Sequential analysis of CD4(+) in blood and intestines of coinfected macaques exhibited pronounced losses of CD4 T cells during the first 2 weeks after SIV infection, followed by transient rebound of CD4 T cells in the gut after C. parvum infection, and then a gradual loss over subsequent months. Persistent cryptosporidiosis was more consistently induced during the acute SIV phase indicating that profound viral damage to gut lymphoid tissue during the acute phase was more conducive, compared with the chronic phase, to establishing persistent cryptosporidiosis than low circulating CD4 T cells.

    The goal of this study was to assess the diagnostic accuracy of acute phase proteins and proinflammatory cytokines in sheep with pneumonic pasteurellosis. Blood samples were collected from 56 sheep (36 naturally infected with Pasteurella multocida and 20 healthy controls) belonging to one farm in Eastern region, Saudi Arabia. Serum samples were evaluated for acute phase proteins (Haptoglobin (Hp), serum amyloid A (SAA) and fibrinogen (Fb)), and the proinflammatory cytokines (interleukins (IL-1α, IL-1β, and IL-6), tumor necrosis factor-alpha (TNF-α), and interferon-gamma (IFN-ϒ)). Additionally, nasopharyngeal swabs and bronchoalveolar lavages were collected from all animals for bacteriological examinations. Receiver operating characteristic curve was used to assess the diagnostic performance of each parameter. All parameters showed moderate to high degree of positive correlation with case-control status. There was no significant difference in the area under the curve (AUC) among acute phase proteins; however, both Hp and SAA showed better sensitivity and specificity than Fb. The proinflammatory cytokines (IL1-α, IL1-β, and IL6) showed similar and highly accurate diagnostic performance (AUC > 0.9), whereas IFN-ϒ was moderately accurate (AUC = 0.79). In conclusion, this study confirms the value of acute phase proteins and cytokines as diagnostic biomarkers of naturally occuring pneumonic pasteurellosis in sheep. PMID:27547520

    This report presents the second phase of a study on thermal treatment technologies. The study consists of a systematic assessment of nineteen thermal treatment alternatives for the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the MLLW. The alternatives considered in Phase 2 were innovative thermal treatments with nine types of primary processing units. Other variations in the study examined the effect of combustion gas, air pollution control system design, and stabilization technology for the treatment residues. The Phase 1 study, the results of which have been published as an interim report, examined ten initial thermal treatment alternatives. The Phase 2 systems were evaluated in essentially the same manner as the Phase 2 systems. The assumptions and methods were the same as for the Phase 1 study. The quantities, and physical and chemical compositions, of the input waste used in he Phase 2 systems differ from those in the Phase 1 systems, which were based on a preliminary waste input database developed at the onset of the Integrated Thermal Treatment System study. The inventory database used in the Phase 2 study incorporates the latest US Department of Energy information. All systems, both primary treatment systems and subsystem inputs, have now been evaluated using the same waste input (2,927 lb/hr).

    We investigated the potential role of interleukin-6 as a mediator of the acute-phase reaction (APR) in patients with acute myocardial infarction. Of the six patients studied, five demonstrated increased plasma interleukin-6 levels. Interleukin-6 levels began to increase at 14 hours (mean; range = 8 to 20 hours) after the initial complaints and reached maximal levels of 28 to 250 U/mL (normal values less than 10 U/mL) after 36 hours (mean; range = 24 to 52 hours). No correlation was seen between the size of the interfaction as indicated by creatine kinase MB assays and the extent of the interleukin-6 increases (r = 0.44; p = 0.38). As an indicator of the APR, plasma C-reactive protein (CRP) levels were measured. CRP levels began to increase after 16 hours (mean; range = 8 to 24 hours) and reached maximum levels of 56 to 322 mg/L (normal values less than 3 mg/L) after 65 hours (mean; range = 48 to 92 hours). The increase of the interleukin-6 level preceded the increase of the CRP level in three patients and was simultaneous in two patients. Maximal interleukin-6 levels correlated significantly with maximal CRP levels (r = 0.96; p = 0.002). Thus these findings indicate that interleukin-6 is an important endogenous mediator for the APR in patients with acute myocardial infarction.

    The present study aims to elucidate in a sequential manner the changes of the blood coagulation process at different phases of experimental schistosomiasis, comprising the pre-patent, acute, intermediate and chronic phases, and the effect of chemotherapeutic cure, at the acute and chronic phases, on reversion of changes related to the coagulation factors. Mice were infected with Schistosoma mansoni cercariae, and were divided into four groups. Blood samples from these groups were collected 32, 70, 100, and 140 days after infection, corresponding to the pre-patent, acute, intermediate and chronic phases, respectively. Simultaneously, other infected groups were given oxamniquine, 70 and 140 days after infection. At the same time as blood collection from infected and/or treated animal groups, other uninfected control animal groups were punctured and maintained under the same conditions as the infected animals. The vitamin-K-dependent clotting factors were found to be more sensitive to infection at different phases, while factors VIII and XI presented hyperactivity. Results obtained 90 days after chemotherapeutic treatment with oxamniquine, administered at the acute and chronic phases, presented noticeable reversion of the main alterations in the coagulation mechanism. The present study provides unquestionable data on the development of hemostatic changes throughout the course of S. mansoni infection.

    We carried out estimations of the following acute phase proteins: C-reactive protein (CRP), alpha-1-antitrypsin (AAT), alpha-1-acid glycoprotein (AAG), alpha-2-ceruloplasmin (CER), and alpha-2-haptoglobin (HPT) in serum and in cerebrospinal fluid (CSF) in patients with bacterial meningitis (BM, n = 30) and viral meningitis (VM, n = 30). We have shown that determinations of concentrations of AAG and CRP in serum and CER in CSF are useful in differentiation between BM and VM. The diagnostic power of these three tests (the areas under their ROC curves equal 0.942, 0.929, and 0.931, respectively) is bigger, though statistically not significantly, than that of traditional parameters of BM in CSF, i.e., total protein concentration and white blood cell count. Determination of AAG, CRP, and AAT in serum is a valuable monitoring marker in the course of BM treatment. Convenience of serum sampling constitutes an advantage over traditional BM parameters in CSF. PMID:8521602

    The study focuses on parents' psychological implications caused by the treatment of their children suffering from tumor. It investigates some specific mothers' resource factors such as their strategies of coping and the perception of their own family functioning in terms of cohesion and adaptability. The study was performed with 34 mothers of children suffering from acute lymphoblastic leukemia (ALL), during the treatment phase. The used tools were the Coping Orientation to Problem Experienced--New Italian Version, to investigate coping strategies, and the Family Adaptability and Cohesion Evaluation Scale-III, to analyze both real and ideal perception of family functioning. The data related to coping, show how the involved mothers tend to mainly use the strategies of positive aptitude, orientation toward problem and social support (F = 99.88, df = 4, P < .01). The family functioning, in terms of adaptability, is described as chaotic relating to both the real (χ(2) = 13.29, df = 3, P = .004) and ideal (χ(2) = 11.52, df = 2, P = .003) family, whereas in terms of cohesion, it is perceived as chiefly disengaged in the real family (χ(2) = 12.3, df = 3, P = .006) and as enmeshed in the ideal one (χ(2) = 12.58, df = 3, P = .006). Statistically positive correlations were only detected between adaptability and avoidance (r = 0.49, P < .01); adaptability and orientation toward problem (r = 0.36, P < .05); and adaptability and transcendent orientation (r = -0.04, P < .05). Despite the critical situation, the mothers have shown optimistic view, care for problem management and capability to ask for help. These coping strategies allow the therapeutic alliance between families and health care workers, so useful for the quality of childcare. PMID:22732085

    Acute heart failure (AHF) represents a major healthcare burden with a high risk of in-hospital and post-discharge mortality, which remained almost unchanged in the last few decades, underscoring the need of new treatments. Relaxin is a naturally occurring human peptide initially identified as a reproductive hormone and has been shown to play a key role in the maternal hemodynamic and renal adjustments that accommodate pregnancy. Recently, the new molecule serelaxin, a recombinant form of the naturally occurring hormone relaxin has been studied in patients hospitalized for AHF. In addition to vasodilation, serelaxin has anti-oxidative, anti-inflammatory and connective tissue regulating properties. In preclinical studies, it reduced both systemic and renal vascular resistance and, in the clinical trials Pre-RELAX-AHF and RELAX-AHF, it improved dyspnea and signs of congestion. In addition, serelaxin was associated with a reduction of 180-day mortality. The aim of this review is to summarize the pharmacological properties of serelaxin and the results of the preclinical and clinical studies. PMID:26294074

The project was summarized in a Science and Technology Review article `Brain Attack` that appeared in June 1997 and again in the Center for Healthcare Technologies Report (UCRL-LR-124761). This article is the best overview of the project, epidemiology of stroke and technical progress. Most of the technical progress has been documented in conference papers and presentations and refereed journal articles. Additional technical publication can be expected as our remaining patent applications progress through the US Patent and Trademark Office. The purpose of this report is to provide an appropriate introduction and organization to the numerous publications so that interested readers can quickly find information. Because there is no documentation for the history of this project, this report provides a summary. It also provides the final status report for the LDRD funding.

    Inhalation of ambient and workplace particulate air pollution is associated with increased risk of cardiovascular disease. One proposed mechanism for this association is that pulmonary inflammation induces a hepatic acute phase response, which increases risk of cardiovascular disease. Induction of the acute phase response is intimately linked to risk of cardiovascular disease as shown in both epidemiological and animal studies. Indeed, blood levels of acute phase proteins, such as C-reactive protein and serum amyloid A, are independent predictors of risk of cardiovascular disease in prospective epidemiological studies. In this review, we present and review emerging evidence that inhalation of particles (e.g., air diesel exhaust particles and nanoparticles) induces a pulmonary acute phase response, and propose that this induction constitutes the causal link between particle inhalation and risk of cardiovascular disease. Increased levels of acute phase mRNA and proteins in lung tissues, bronchoalveolar lavage fluid and plasma clearly indicate pulmonary acute phase response following pulmonary deposition of different kinds of particles including diesel exhaust particles, nanoparticles, and carbon nanotubes. The pulmonary acute phase response is dose-dependent and long lasting. Conversely, the hepatic acute phase response is reduced relative to lung or entirely absent. We also provide evidence that pulmonary inflammation, as measured by neutrophil influx, is a predictor of the acute phase response and that the total surface area of deposited particles correlates with the pulmonary acute phase response. We discuss the implications of these findings in relation to occupational exposure to nanoparticles.

    Purpose Second malignant neoplasms (SMNs) after diagnosis of childhood acute lymphoblastic leukemia (ALL) are rare events. Patients and Methods We analyzed data on risk factors and outcomes of 642 children with SMNs occurring after treatment for ALL from 18 collaborative study groups between 1980 and 2007. Results Acute myeloid leukemia (AML; n = 186), myelodysplastic syndrome (MDS; n = 69), and nonmeningioma brain tumor (n = 116) were the most common types of SMNs and had the poorest outcome (5-year survival rate, 18.1% ± 2.9%, 31.1% ± 6.2%, and 18.3% ± 3.8%, respectively). Five-year survival estimates for AML were 11.2% ± 2.9% for 125 patients diagnosed before 2000 and 34.1% ± 6.3% for 61 patients diagnosed after 2000 (P < .001); 5-year survival estimates for MDS were 17.1% ± 6.4% (n = 36) and 48.2% ± 10.6% (n = 33; P = .005). Allogeneic stem-cell transplantation failed to improve outcome of secondary myeloid malignancies after adjusting for waiting time to transplantation. Five-year survival rates were above 90% for patients with meningioma, Hodgkin lymphoma, thyroid carcinoma, basal cell carcinoma, and parotid gland tumor, and 68.5% ± 6.4% for those with non-Hodgkin lymphoma. Eighty-nine percent of patients with brain tumors had received cranial irradiation. Solid tumors were associated with cyclophosphamide exposure, and myeloid malignancy was associated with topoisomerase II inhibitors and starting doses of methotrexate of at least 25 mg/m2 per week and mercaptopurine of at least 75 mg/m2 per day. Myeloid malignancies with monosomy 7/5q− were associated with high hyperdiploid ALL karyotypes, whereas 11q23/MLL-rearranged AML or MDS was associated with ALL harboring translocations of t(9;22), t(4;11), t(1;19), and t(12;21) (P = .03). Conclusion SMNs, except for brain tumors, AML, and MDS, have outcomes similar to their primary counterparts. PMID:23690411

    Introduction Clinical trials of new treatments for rheumatoid arthritis (RA) typically require subjects to have an elevated acute phase reactant (APR), in addition to tender and swollen joints. However, despite the elevation of individual components of the Clinical Disease Activity Index (CDAI) (tender and swollen joint counts and patient and physician global assessment), some patients with active RA may have normal erythrocyte sedimentation rate (ESR) and/or C-reactive protein (CRP) levels and thus fail to meet entry criteria for clinical trials. We assessed the relationship between CDAI and APRs in the Consortium of Rheumatology Researchers of North America (CORRONA) registry by comparing baseline characteristics and one-year clinical outcomes of patients with active RA, grouped by baseline APR levels. Methods This was an observational study of 9,135 RA patients who had both ESR and CRP drawn and a visit at which CDAI was >2.8 (not in remission). Results Of 9,135 patients with active RA, 58% had neither elevated ESR nor CRP; only 16% had both elevated ESR and CRP and 26% had either ESR or CRP elevated. Among the 4,228 patients who had a one-year follow-up visit, both baseline and one-year follow-up modified Health Assessment Questionnaire (mHAQ) and CDAI scores were lowest for patients with active RA but with neither APR elevated; both mHAQ and CDAI scores increased sequentially with the increase in number of elevated APR levels at baseline. Each individual component of the CDAI followed the same trend, both at baseline and at one-year follow-up. The magnitude of improvement in both CDAI and mHAQ scores at one year was associated positively with the number of APRs elevated at baseline. Conclusions In a large United States registry of RA patients, APR levels often do not correlate with disease activity as measured by joint counts and global assessments. These data strongly suggest that it is appropriate to obtain both ESR and CRP from RA patients at the initial

    Acute rheumatic fever (ARF) is associated with systemic inflammation and arterial stiffness during the acute stage. It has not been reported if arterial stiffness remains after recovery. The aim of this study was to determine the arterial stiffness during acute stage and 6 months after recovery from ARF. Arterial stiffness was assessed by carotid femoral pulse wave velocity (PWV) in 23 ARF patients during the acute stage of ARF and 6 months later. Simultaneously, erythrocyte sedimentation rate (ESR) and other anthropometric measurements were taken during both stages. There was a significant reduction in PWV; 6.5 (6.0, 7.45) m/s to 5.9 (5.38, 6.48) m/s, p=0.003 6 months after the acute stage of ARF. Similarly, ESR was also significantly reduced from 92.0 (37.5, 110.50) mm/hr to 7.0 (5.0, 16.0) mm/hr, p=0.001. In conclusion, arterial stiffness improved 6 months after the acute stage with routine aspirin treatment; this correlates well with the reduction in systemic inflammation. PMID:27130739

    Background Acute phase proteins haptoglobin (Hp), serum amyloid A (SAA) and lipopolysaccharide binding protein (LBP) have suggested to be suitable inflammatory markers for bovine mastitis. The aim of the study was to investigate acute phase markers along with clinical parameters in two consecutive intramammary challenges with Escherichia coli and to evaluate the possible carry-over effect when same animals are used in an experimental model. Methods Mastitis was induced with a dose of 1500 cfu of E. coli in one quarter of six cows and inoculation repeated in another quarter after an interval of 14 days. Concentrations of acute phase proteins haptoglobin (Hp), serum amyloid A (SAA) and lipopolysaccharide binding protein (LBP) were determined in serum and milk. Results In both challenges all cows became infected and developed clinical mastitis within 12 hours of inoculation. Clinical disease and acute phase response was generally milder in the second challenge. Concentrations of SAA in milk started to increase 12 hours after inoculation and peaked at 60 hours after the first challenge and at 44 hours after the second challenge. Concentrations of SAA in serum increased more slowly and peaked at the same times as in milk; concentrations in serum were about one third of those in milk. Hp started to increase in milk similarly and peaked at 36–44 hours. In serum, the concentration of Hp peaked at 60–68 hours and was twice as high as in milk. LBP concentrations in milk and serum started to increase after 12 hours and peaked at 36 hours, being higher in milk. The concentrations of acute phase proteins in serum and milk in the E. coli infection model were much higher than those recorded in experiments using Gram-positive pathogens, indicating the severe inflammation induced by E. coli. Conclusion Acute phase proteins would be useful parameters as mastitis indicators and to assess the severity of mastitis. If repeated experimental intramammary induction of the same animals

    Effects of acute and chronic tianeptine treatments on ethanol withdrawal syndrome were investigated in rats. Ethanol (7.2% v/v) was given to adult male Wistar rats by a liquid diet for 30 days. Acute or chronic (twice daily) tianeptine (5, 10 and 20 mg/kg) and saline were administered to rats intraperitoneally. Acute and last chronic tianeptine injections and saline were done 30 min before ethanol withdrawal testing. After 2nd, 4th and 6th hours of ethanol withdrawal, rats were observed for 5 min, and withdrawal signs which included locomotor hyperactivity, agitation, tremor, wet dog shakes, stereotyped behavior and audiogenic seizures were recorded or rated. Locomotor activity in naive (no ethanol-dependent rats) was also tested after acute tianeptine treatments. Acute but not chronic tianeptine treatment attenuated locomotor hyperactivity and agitation in ethanol-dependent rats. Both acute and chronic tianeptine treatment produced some significant inhibitory effects on tremor, wet dog shakes, stereotyped behaviors and audiogenic seizures during the ethanol withdrawal. Our results suggest that acute or chronic tianeptine treatment attenuates ethanol withdrawal syndrome in ethanol-dependent rats and this drug may be useful for treatment of ethanol-type dependence.

    An acute pharyngitis is characterised by mild to severe sore throat mostly accompanied by inflammation, throat pain, pain on swallowing, and burning. This randomised, double-blind, placebo-controlled phase III study was conducted for comparison of the efficacy and safety of a newly developed lidocaine (2-(diethylamino)-N-(2,6-dimethylphenyl) acetamide, CAS 137-58-6) 8 mg lozenge formulation (Trachisan Halsschmerztabletten) for the treatment of acute sore throat not necessarily to be treated with antibiotics. 240 patients of both genders were enrolled. The study was performed in a single centre setting and consisted of two parts. A 2-h stationary phase (single dose treatment) was directly followed by a 46-h ambulatory phase, where patients were allowed to take up to a maximum of 11 further lozenges (multiple dose treatment). Pain intensity was assessed via Visual Analogue Scale during the course of the study. Moreover, the global efficacy and tolerability of the treatments were assessed. Lidocaine 8 mg sore throat lozenges were found to be superior to placebo for all efficacy parameters investigated. For the primary efficacy parameter, area under the curve of pain intensity from baseline over 2 h (AUC(0-2h)), i.e. after single-dose treatment, a significant treatment difference with a p-value of p < 0.001 in favour of the verum treatment could be demonstrated. Significant superiority could also be demonstrated for the descriptive AUC(0-48h) values, reflecting the treatment effect during the ambulatory multiple dose phase. Pain relief, minimum pain intensity, meaningful pain relief and the time of onset of meaningful pain relief as well as the assessments of global efficacy underlined the superiority of the treatment with lidocaine 8 mg sore throat lozenges. Global tolerability of the verum treatment was rated as "good" or "very good" in the majority of cases, the number of study drug related adverse events was low and evenly distributed to both treatment groups

    Background Older age has historically been an adverse prognostic factor in pediatric acute myeloid leukemia (AML). The impact of age relative to that of other prognostic factors on the outcome of patients treated in recent trials is unknown. Methods Clinical outcome and causes of treatment failure of 351 patients enrolled on three consecutive protocols for childhood AML between 1991 and 2008 were analyzed according to age and protocol. Results The more recent protocol (AML02) produced improved outcomes for 10- to 21-year-old patients compared to 2 earlier studies (AML91 and 97), with 3-year rates of event-free survival (EFS), overall survival (OS) and cumulative incidence of refractory leukemia or relapse (CIR) for this group similar to those of 0- to 9-year old patients: EFS, 58.3% ± 5.4% vs. 66.6% ± 4.9%, P=.20; OS, 68.9% ± 5.1% vs. 75.1% ± 4.5%, P=.36; cumulative incidence of refractory leukemia or relapse, 21.9% ± 4.4%; vs. 25.3% ± 4.1%, P=.59. EFS and OS estimates for 10–15-year-old patients overlapped those for 16–21-year-old patients. However, the cumulative incidence of toxic death was significantly higher for 10- to 21-year-old patients compared to younger patients (13.2% ± 3.6 vs. 4.5% ± 2.0%, P=.028). Conclusion The survival rate for older children with AML has improved on our recent trial and is now similar to that of younger patients. However, deaths from toxicity remain a significant problem in the older age group. Future trials should focus on improving supportive care while striving to develop more effective antileukemic therapy. PMID:22674050

    RNA interference has tremendous yet unrealized potential to treat a wide range of illnesses. Innovative solutions are needed to protect and selectively deliver small interfering RNA (siRNA) cargo to and within a target cell to fully exploit siRNA as a therapeutic tool in vivo. Herein, we describe ammonium-functionalized carbon nanotube (fCNT)–mediated transport of siRNA selectively and with high efficiency to renal proximal tubule cells in animal models of acute kidney injury (AKI). fCNT enhanced siRNA delivery to tubule cells compared to siRNA alone and effectively knocked down the expression of several target genes, including Trp53, Mep1b, Ctr1, and EGFP. A clinically relevant cisplatin-induced murine model of AKI was used to evaluate the therapeutic potential of fCNT-targeted siRNA to effectively halt the pathogenesis of renal injury. Prophylactic treatment with a combination of fCNT/siMep1b and fCNT/siTrp53 significantly improved progression-free survival compared to controls via a mechanism that required concurrent reduction of meprin-1β and p53 expression. The fCNT/siRNA was well tolerated, and no toxicological consequences were observed in murine models. Toward clinical application of this platform, fCNTs were evaluated for the first time in nonhuman primates. The rapid and kidney-specific pharmacokinetic profile of fCNT in primates was comparable to what was observed in mice and suggests that this approach is amenable for use in humans. The nanocarbon-mediated delivery of siRNA provides a therapeutic means for the prevention of AKI to safely overcome the persistent barrier of nephrotoxicity during medical intervention.

  13. 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. Ongoing studies are

    In this randomised, double-blind study carried out in 28 centres, azithromycin (500 mg single dose on day 1, followed by 250 mg once-daily on days 2-5) was compared with cefaclor (500 mg t.i.d. for 10 days) in the treatment of acute bacterial pneumonia. A total of 119 patients entered the study, and of these 71 were evaluable and included in the efficacy analysis. The overall satisfactory clinical response was 97.3% for azithromycin patients and 100% for cefaclor patients. The clinical cure rates of azithromycin and cefaclor were 46.9% and 41.0%, respectively; improvement was seen in an additional 46.9% of azithromycin-treated patients and in 59.0% of the cefaclor group. The bacteriological eradication rates were 80.4% and 92.6%, respectively. These rates of clinical and bacteriological efficacy, were not statistically different. Both antibiotics were well tolerated during the study; only two patients (one on each study drug) discontinued medication due to adverse events. The overall incidence of side effects was 18.9% (10 of 53 patients) for azithromycin- and 12.1% (eight of 66 patients) for cefaclor-treated patients. Gastrointestinal disturbances were the most commonly reported side effects (nine of 10 azithromycin-treated patients and six of eight cefaclor-treated patients). In addition, two cefaclor patients reported headache. All azithromycin side effects were mild or moderate in severity, but there were two severe occurrences in the cefaclor group (1 nausea, 1 vomiting) the later leading to discontinuation.(ABSTRACT TRUNCATED AT 250 WORDS)

    Acute appendicitis is a common cause of acute abdominal pain and the most frequent cause of emergency abdominal surgery. In the last two decades, growing evidence has been published about the use of antibiotics as the exclusive treatment for acute appendicitis. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified only one systematic review including one pertinent randomized trial. We generated a summary of findings following the GRADE approach. We concluded the use of antibiotics to treat acute uncomplicated appendicitis may be less effective than appendectomy and probably increases major complications compared with appendectomy.

    Background: Peripancreatic fluid collection suggests the anatomical-clinical scenario of necrotizing acute pancreatitis. However, intrahepatic fluid collection is a rare occurrence with fewer than 30 cases being reported in the medical literature. We describe 2 cases of intrahepatic fluid collection in 2 patients with acute biliary pancreatitis and discuss the therapeutic possibilities. Case Reports: The first case report is that of a 68-year-old female with a diagnosis of acute biliary pancreatitis with several necrotizing fluid collections and a large infected intrahepatic collection in the left lobe. The patient was successfully treated by percutaneous US/CT guided drainage. The second case report is that of a 72-year-old female with a diagnosis of acute biliary pancreatitis with several peripancreatic fluid collections and a voluminous intrahepatic fluid collection in the left lobe that caused epigastric pain. This patient was also successfully treated with percutaneous US/CT guided drainage. Conclusion: Intrahepatic fluid collection in the course of acute biliary pancreatitis is a rare occurrence. The therapeutic approach is the same as that for pancreatic and peripancreatic fluid collections. In case of infection, the patient undergoes percutaneous US/CT guided drainage. This therapeutic procedure can be added to the therapeutic program for necrotizing acute biliary pancreatitis together with ERCP/ES and videolaparocholecystectomy (VLC). PMID:19660231

    The ability to design, build and test miniaturized acoustic treatment panels on scale model fan rigs representative of full scale engines provides not only cost-savings, but also an opportunity to optimize the treatment by allowing multiple tests. To use scale model treatment as a design tool, the impedance of the sub-scale liner must be known with confidence. This study was aimed at developing impedance measurement methods for high frequencies. A normal incidence impedance tube method that extends the upper frequency range to 25,000 Hz. without grazing flow effects was evaluated. The free field method was investigated as a potential high frequency technique. The potential of the two-microphone in-situ impedance measurement method was evaluated in the presence of grazing flow. Difficulties in achieving the high frequency goals were encountered in all methods. Results of developing a time-domain finite difference resonator impedance model indicated that a re-interpretation of the empirical fluid mechanical models used in the frequency domain model for nonlinear resistance and mass reactance may be required. A scale model treatment design that could be tested on the Universal Propulsion Simulator vehicle was proposed.

    Purpose: Topotecan (TPT), a camptothecin analog, is currently used to treat human ovarian and small-cell lung cancer and is in clinical trials for other tumor sites. However, it is unknown whether chronomodulation of TPT treatment is beneficial. We examined the effects of administering TPT or X-radiation (XR) alone at different times of the day or night. Methods: We treated mice bearing human colorectal tumor xenografts at four different times representing the early rest period (9 AM or 3 HALO [hours after light onset]), late rest period (3 PM or 9 HALO), early active period (9 PM or 15 HALO), and late active period (3 AM or 21 HALO) of the mice. We gave either TPT (12 mg/kg, injected i.p.) or XR (4 Gy, directed to the tumor) twice weekly on Days 0, 4, 7, 10 within 2 weeks. Results: Treatment with either TPT or XR at 3 AM demonstrated the greatest efficacy (measured by a tumor regrowth assay) without significantly increasing acute toxicity (assessed by a decrease in leukocyte counts or body weight). Conversely, treatment at 3 PM, in particular, showed increased toxicity without any enhanced efficacy. Conclusions: Our study provided the first evidence that chronomodulation of TPT treatments, consistent with the findings of other camptothecin analogs, is potentially clinically beneficial. Additionally, our findings suggest that chronomodulation of fractionated XR treatments is also potentially clinically beneficial.

    Kynurenines are a wide range of catabolites which derive from tryptophan through the “Kynurenine Pathway” (KP). In addition to its peripheral role, increasing evidence shows a role of the KP in the central nervous system (CNS), mediating both physiological and pathological functions. Indeed, an imbalance in this route has been associated with several neurodegenerative disorders such as Alzheimer’s and Huntington’s diseases. Altered KP catabolism has also been described during both acute and chronic phases of stroke; however the contribution of the KP to the pathophysiology of acute ischemic damage and of post-stroke disorders during the chronic phase including depression and vascular dementia, and the exact mechanisms implicated in the regulation of the KP after stroke are not well established yet. A better understanding of the regulation and activity of the KP after stroke could provide new pharmacological tools in both acute and chronic phases of stroke. In this review, we will make an overview of CNS modulation by the KP. We will detail the KP contribution in the ischemic damage, how the unbalance of the KP might trigger an alteration of the cognitive function after stroke as well as potential targets for the development of new drugs.

    Poststroke depression (PSD) is a critical complication which might lead to unfavorable outcomes. However, most cases of PSD in the acute phase, during the 2 or 3 weeks following a stroke, are neglected because of the variable comorbid conditions. In this study, aimed at revealing the outstanding symptoms of PSD during the acute phase, consecutive patients with intracranial hemorrhage (ICH) or brain infarction (BI) were asked to fill out a depression questionnaire (Quick Inventory of Depressive Symptomatology Self-Report: QIDS-SR) at 1 week and 1 month following stroke onset. Patients with disturbed consciousness or aphasia were excluded from this study. Forty-nine ICH patients and 222 BI patients completed the QIDS-SR at 1 week and 27 of ICH and 62 of BI at 1 month. The PSD rate was 67% and 46% at 1 week in ICH and BI, respectively. Although sleep disturbance was the most frequent symptom of PSD, psychomotor agitation and appetite disturbance were the most distinguishing symptoms in ICH at 1 week and fatigue at 1 month. On the other hand, most of the depressive symptoms addressed in QIDS-SR were observed in PSD of BI patients both at 1 week and 1 month. In conclusion, while sleep disturbance was a frequent but non-specific symptom, appetite disturbance and fatigue might be critical symptoms to suggest PSD during the acute phase of stroke.

    The present study aimed to assess potential changes in acute phase proteins in sheep experimentally infected with Trypanosoma vivax. There were studied eight male sheep, four used as controls and four infected with 10(5) T. vivax trypomastigotes. Blood samples were collected at two points times before infection and then at 5,7, 9, 11, 13, 15, 20, 30, 45, 60, 75, 90, 105 and 120 days post-infection (dpi). Blood samples were centrifuged and allotted, and acute phase proteins were then separated by electrophoresis on acrylamide gel containing sodium dodecyl sulfate. Protein concentrations were determined by computer-assisted densitometry. Total protein was determined by colorimetric biuret method. Trypanosomes were counted daily using a 5 mL aliquot of blood smear on a glass slide under a 22 × 22 mm coverslip. Parasites were counted in 100 microscopic fields (40× magnification), and then multiplied by a correction factor. The results were expressed as parasites per mL of blood. For statistical analyses, we used the Wilcoxon test at 5% significance level. There was found a reduction in several acute phase proteins and increase in antitrypsin and transferrin. This finding can be used for the diagnosis of T. vivax infection, especially in chronic infection.

  4. Placental thrombosis in acute phase abortions during experimental Toxoplasma gondii infection in sheep

    PubMed Central

    2014-01-01

    After oral administration of ewes during mid gestation with 2000 freshly prepared sporulated oocysts of T. gondii isolate M4, abortions occurred between days 7 and 11 in 91.6% of pregnant and infected ewes. Afterwards, a further infection was carried out at late gestation in another group of sheep with 500 sporulated oocysts. Abortions happened again between days 9 and 11 post infection (pi) in 58.3% of the infected ewes. Classically, abortions in natural and experimental ovine toxoplasmosis usually occur one month after infection. Few experimental studies have reported the so-called acute phase abortions as early as 7 to 14 days after oral inoculation of oocysts, and pyrexia was proposed to be responsible for abortion, although the underline mechanism was not elucidated. In the present study, all placentas analysed from ewes suffering acute phase abortions showed infarcts and thrombosis in the caruncullar villi of the placentomes and ischemic lesions (periventricular leukomalacia) in the brain of some foetuses. The parasite was identified by PCR in samples from some placentomes of only one sheep, and no antigen was detected by immunohistochemical labelling. These findings suggest that the vascular lesions found in the placenta, and the consequent hypoxic damage to the foetus, could be associated to the occurrence of acute phase abortions. Although the pathogenesis of these lesions remains to be determined, the infectious dose or virulence of the isolate may play a role in their development. PMID:24475786

    Chagas disease, caused by the intracellular protozoan Trypanosoma cruzi, is associated with inflammation, discomfort and pain during the acute phase. The influence of TNF-α (tumor necrosis factor) in this disease outcome is controversial. In this way, the aim of this work was to determine the role of the TNF-α blocker etanercept in the pain, discomfort, and survival during the Chagas' acute phase of mice experimentally infected with a wild virulent strain of T. cruzi. The infection with this wild strain was responsible for a severe visceral inflammation and said parasite showed a tropism in peritoneal fluid cells. Etanercept was able to restore spontaneous vertical and horizontal activities during the second week after infection and to abolish mechanical allodynia during the first week after infection. Finally, etanercept delayed the mortality without any effect on the parasitemia rates. This is the first report that correlates sickness behavior and allodynia with TNF-α and suggests that this cytokine may play an important role in the physiopathology of the acute phase.

    After oral administration of ewes during mid gestation with 2000 freshly prepared sporulated oocysts of T. gondii isolate M4, abortions occurred between days 7 and 11 in 91.6% of pregnant and infected ewes. Afterwards, a further infection was carried out at late gestation in another group of sheep with 500 sporulated oocysts. Abortions happened again between days 9 and 11 post infection (pi) in 58.3% of the infected ewes. Classically, abortions in natural and experimental ovine toxoplasmosis usually occur one month after infection. Few experimental studies have reported the so-called acute phase abortions as early as 7 to 14 days after oral inoculation of oocysts, and pyrexia was proposed to be responsible for abortion, although the underline mechanism was not elucidated. In the present study, all placentas analysed from ewes suffering acute phase abortions showed infarcts and thrombosis in the caruncullar villi of the placentomes and ischemic lesions (periventricular leukomalacia) in the brain of some foetuses. The parasite was identified by PCR in samples from some placentomes of only one sheep, and no antigen was detected by immunohistochemical labelling. These findings suggest that the vascular lesions found in the placenta, and the consequent hypoxic damage to the foetus, could be associated to the occurrence of acute phase abortions. Although the pathogenesis of these lesions remains to be determined, the infectious dose or virulence of the isolate may play a role in their development.

    Our objective was to evaluate the effects of MP supply, through RUP supplementation, on the acute-phase response of beef steers following vaccination. On d 0, Brangus-crossbred steers (n = 24; 173 ± 31 kg; 175 ± 16 d of age) were randomly assigned to receive 1 of 3 isocaloric diets formulated to provide 85, 100, and 115% of the daily MP requirements of a beef steer gaining 0.66 kg of BW daily. Diets were limit-fed at 1.8% of BW (DM basis) and individually provided to steers once daily (0800 h) from d 0 to 29. Steers were weighed on d 0 and 29, following a 12-h period of feed and water withdrawal. On d 7, steers were vaccinated against Mannheimia haemolytica (OneShot, Pfizer), and blood samples were collected on d 0, 7, 8, 10, 14, 21, and 30. Plasma metabolites were analyzed as repeated measures using the MIXED procedure of SAS. Final BW and ADG were similar (P ≥ 0.50) among treatments (mean = 184 ± 9 kg and 0.5 ± 0.08 kg/d, respectively). Effects of time were detected (P < 0.01) for plasma concentrations of all acute-phase proteins, which peaked between d 7 to 14, returning to baseline concentrations by d 29. Treatment effects were not detected (P ≥ 0.19) for plasma concentrations of acid-soluble protein, albumin, fibrinogen, IGF-1 and serum amyloid-A. Plasma concentrations of total protein (TP) and plasma urea nitrogen (PUN) increased (P ≤ 0.05) with increasing supply of MP (87.1, 89.6, and 90.1 ± 1.09 mg TP/mL and 6.1, 8.3, and 10.3 ± 0.41 mg PUN/dL for 85, 100, and 115% MP steers, respectively). From d 10 to 29, steers provided 115% MP had less (P < 0.001) plasma concentrations of ceruloplasmin than steers fed 85 and 100% MP, which had similar plasma ceruloplasmin concentrations. On d 14, plasma concentrations of haptoglobin were greatest (P ≤ 0.06) for steers fed 115% MP, intermediate for 100% MP, and least for 85% MP (0.98, 0.71 and 0.44 ± 0.099 mg/mL, respectively). On d 10, plasma concentrations of creatinine were greater (P = 0.01) for steers

    Treatment of solid tumors by photodynamic therapy (PDT) was recently shown to trigger a strong acute phase response. Using the mouse Lewis lung carcinoma (LLC) model, the present study examined complement and pentraxin proteins as PDT-induced acute phase reactants. The results show a distinct pattern of changes in the expression of genes encoding these proteins in the tumor, as well as host liver and spleen, following PDT mediated by photosensitizer Photofrin™. These changes were influenced by glucocorticoid hormones, as evidenced by transcriptional activation of glucocorticoid receptor and the upregulation of gene encoding this receptor. The expression of gene for glucocorticoid-induced zipper (GILZ) protein, whose activity is particularly susceptible to glucocorticoid regulation, was also changed in PDT-treated tumors. A direct demonstration that tumor PDT induces glucocorticoid hormone upregulation is provided by documenting elevated levels of serum corticosterone in mice bearing PDT-treated LLC tumors. Tumor response to PDT was negatively affected by blocking glucocorticoid receptor activity, which suggests that glucocorticoid hormones have a positive impact on the therapeutic outcome with this therapy.

    There is no standard approved treatment for acute hepatitis C and the combination of pegylated interferon-alpha and ribavirin, currently recognized as the standard of care for chronic hepatitis C, has not been evaluated for acute hepatitis C. Adverse events induced by interferon therapy are numerous but myopathy is rare and has not been described with the use of pegylated interferon-alpha. We report the case of a 33-year-old Caucasian man who was successfully treated for acute hepatitis C with the combination of pegylated interferon-alpha2b and ribavirin, and who during treatment developed myopathy which proved reversible.

    Standard imaging in acute stroke is undertaken with the aim of diagnosing the underlying cause and excluding stroke mimics. In the presence of ischaemic stroke, imaging is also needed to assess patient suitability for treatment with intravenous thrombolysis. Non-contrast CT is predominantly used, but MRI can also exclude any contraindications to thrombolysis treatment. Advanced stroke imaging such as CT and MR angiography and perfusion imaging are increasingly used in an acute setting. In this review, we discuss the evidence for the application of these advanced techniques in the imaging of acute stroke. PMID:24936980

    This report presents the second phase of a study on thermal treatment technologies. The study consists of a systematic assessment of nineteen thermal treatment alternatives for the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the MLLW. The alternatives considered in Phase 2 were innovative thermal treatments with nine types of primary processing units. Other variations in the study examined the effect of combustion gas, air pollution control system design, and stabilization technology for the treatment residues. The Phase 1 study examined ten initial thermal treatment alternatives. The Phase 2 systems were evaluated in essentially the same manner as the Phase 1 systems. The alternatives evaluated were: rotary kiln, slagging kiln, plasma furnace, plasma gasification, molten salt oxidation, molten metal waste destruction, steam gasification, Joule-heated vitrification, thermal desorption and mediated electrochemical oxidation, and thermal desorption and supercritical water oxidation. The quantities, and physical and chemical compositions, of the input waste used in the Phase 2 systems differ from those in the Phase 1 systems, which were based on a preliminary waste input database developed at the onset of the Integrated Thermal Treatment System study. The inventory database used in the Phase 2 study incorporates the latest US Department of Energy information. All systems, both primary treatment systems and subsystem inputs, have now been evaluated using the same waste input (2,927 lb/hr). 28 refs., 88 figs., 41 tabs.

    Drug delivery to tumors is limited by several factors, including drug permeability of the target cell plasma membrane. Ultrasound in combination with microbubbles (USMB) is a promising strategy to overcome these limitations. USMB treatment elicits enhanced cellular uptake of materials such as drugs, in part as a result of sheer stress and formation of transient membrane pores. Pores formed upon USMB treatment are rapidly resealed, suggesting that other processes such as enhanced endocytosis may contribute to the enhanced material uptake by cells upon USMB treatment. How USMB regulates endocytic processes remains incompletely understood. Cells constitutively utilize several distinct mechanisms of endocytosis, including clathrin-mediated endocytosis (CME) for the internalization of receptor-bound macromolecules such as Transferrin Receptor (TfR), and distinct mechanism(s) that mediate the majority of fluid-phase endocytosis. Tracking the abundance of TfR on the cell surface and the internalization of its ligand transferrin revealed that USMB acutely enhances the rate of CME. Total internal reflection fluorescence microscopy experiments revealed that USMB treatment altered the assembly of clathrin-coated pits, the basic structural units of CME. In addition, the rate of fluid-phase endocytosis was enhanced, but with delayed onset upon USMB treatment relative to the enhancement of CME, suggesting that the two processes are distinctly regulated by USMB. Indeed, vacuolin-1 or desipramine treatment prevented the enhancement of CME but not of fluid phase endocytosis upon USMB, suggesting that lysosome exocytosis and acid sphingomyelinase, respectively, are required for the regulation of CME but not fluid phase endocytosis upon USMB treatment. These results indicate that USMB enhances both CME and fluid phase endocytosis through distinct signaling mechanisms, and suggest that strategies for potentiating the enhancement of endocytosis upon USMB treatment may improve targeted

    Acute mesenteric ischemia is an uncommon but highly complex clinical problem and carries a high mortality. Traditional treatment has yielded only modest improvements in mortality and an endovascular first treatment paradigm has been adopted by selected centers over the past decade. However, the technique does not allow for immediate assessment of intestinal viability and availability of the expertise and equipment is mostly limited to tertiary referral centers. Experience gained with endovascular treatment thus far suggests that careful patient selection, procedure planning, and meticulous technique are the key to further improving results. Most important, prolonged attempts at percutaneous intervention should not be allowed to delay laparotomy and bowel assessment. In patients requiring urgent laparotomy, intraoperative retrograde superior mesenteric artery recanalization remains an attractive option and should be given due consideration. Liberal use of second-look laparotomy is to be encouraged for continued bowel assessment and eventual reestablishment of bowel continuity. Early recognition of the problem with expeditious implementation of the appropriate treatment is likely to improve outcomes of this challenging problem in the future.

    The acute phase response as indicated by serum haptoglobin and total haemolytic complement activity (CH50) was measured in 72 cross-bred steer calves purchased at sales in Ontario. During the 28 day (d) trial, 18 steers were randomly assigned to each of the following groups: 1) control; 2) vaccinated (Infectious Bovine Rhinotracheitis, Parainfluenza-3, Bovine Viral Diarrhea, Bovine Respiratory Synctial Virus vaccine plus Pasteurella haemolytica vaccine); 3) supplemental chelated Cr (0.14 mg/kg); and 4) Cr plus vaccines. Haptoglobin concentrations were low at arrival, increased (P < 0.05) on day 7, and returned to near initial levels (P > 0.05) by day 14. Supplemental Cr reduced (P < 0.05) haptoglobin on day 7 when morbidity was highest. Following antibiotic treatment for respiratory disease haptoglobin was lower (P < 0.05) than during morbidity; however, during morbidity, haptoglobin concentrations were not greater in sick calves (P > 0.05) than in healthy calves. Complement activity was lowest on day 7 (P < 0.05) and peaked on day 14 (P < 0.05). Complement activity tended to be lower on day 7 for vaccine, Cr, and Cr+ vaccine groups; however, the difference from controls was not significant (P > 0.10). Complement activity did not increase on day 14 (P > 0.05) with Cr supplementation as in other treatments. Morbid calves had lower (P < 0.05) CH50 activity than healthy calves on day 14. Following antibiotic treatment, the Cr-supplemented group had higher (P < 0.05) CH50 than during morbidity. In general, chromium supplementation reduced the acute phase response in newly arrived feeder calves. PMID:8548694

    The aim of this study was to evaluate the role of butyrylcholinesterase (BChE) as a marker of inflammation and liver injury in the acute and subclinical phases of canine ehrlichiosis. Forty-two serum samples of dogs naturally infected with Ehrlichia canis were used, of which 24 were from animals with the acute phase of the disease and 18 with subclinical disease. In addition, sera from 17 healthy dogs were used as negative controls. The hematocrit, BChE activity, hepatic injury (alanine aminotransferase (ALT) and aspartate aminotransferase (AST)), nitric oxide, and cytokines levels were evaluated. The BChE activity was significantly elevated (P<0.05) in dogs with the acute phase of the disease when compared to healthy animals. However, there was a reduction on BChE activity on dogs with subclinical disease compared to the other two groups. AST and ALT levels were significantly higher (P<0.05) in the acute phase, as well as the inflammatory mediators (NOx, TNF-α, INF-γ, IL-4, IL-6) when compared to the control group. On the other hand, IL-10 levels were lower in the acute phase. Based on these results, we are able to conclude that the acute infection caused by E. canis in dogs leads to an increase on seric BChE activity and some inflammatory mediators. Therefore, this enzyme might be used as a marker of acute inflammatory response in dogs naturally infected by this bacterium. PMID:26616656

    Hypertension is the leading risk factor for ischemic and intracerebral hemorrhagic subtypes of stroke. Additionally, high blood pressure (BP) in the acute cerebrovascular event is associated with poor outcome, and a high percentage of stroke survivors have inadequate control of hypertension. The present is a systematic review of prospective, randomized, and controlled trials carried out on safety and efficacy of antihypertensive treatment of both subtypes of acute stroke. Six trials involving 7512 patients were included, which revealed controversies on the speed and the goals of treatment. These controversies could be due at least in part, from the fact that some studies analyzed the results of antihypertensive treatment in ischemic and intracerebral hemorrhagic subtypes of acute stroke together, and from a different prevalence of past-stroke in the randomized groups. Further research is necessary to establish whether standard antihypertensive treatment provides greater benefit than simple observation in patients with ischemic acute stroke and Stage 2 hypertension of JNC 7, albeit they were not candidates for acute reperfusion. In that case, the target reduction in BP could be 10% to 15% within 24 hours. The recently published INTERACT 2 has provided evidence that patients with hemorrhagic stroke may receive intensive antihypertensive treatment safely with the goal of reducing systolic BP to levels no lower than 130 mm Hg. It is important to take into account that marked BP lowering in acute stroke increases the risk of poor outcome by worsening cerebral ischemia from deterioration of cerebral blood flow autoregulation.

    Our aim is to present midterm results after endovascular repair of acute and chronic blunt aortic injury. Between December 1999 and December 2005, 13 patients were endovascularly treated for blunt aortic injury. Ten patients, 8 men and 2 women, mean age 38.7 years, were treated for acute traumatic injury in the isthmus region of thoracic aorta. Stent-graftings were performed between the fifth hour and the sixth day after injury. Three patients (all males; mean age, 66 years; range, 59-71 years) were treated due to the presence of symptoms of chronic posttraumatic pseudoaneurysm of the thoracic aorta (mean time after injury, 29.4 years, range, 28-32). Fifteen stent-grafts were implanted in 13 patients. In the group with acute aortic injury one patient died due to failure of endovascular technique. Lower leg paraparesis appeared in one patient; the other eight patients were regularly followed up (1-72 months; mean, 35.6 months), without complications. In the group with posttraumatic pseudoaneurysms all three patients are alive. One patient suffered postoperatively from upper arm claudication, which was treated by carotidosubclavian bypass. We conclude that the endoluminal technique can be used successfully in the acute repair of aortic trauma and its consequences. Midterm results are satisfactory, with a low incidence of neurologic complications.

    Background To differentiate the features of electroencephalography (EEG) after status epileptics in febrile children with final diagnosis of either febrile seizure (FS) or acute encephalopathy for an early diagnosis. Methods We retrospectively collected data from 68 children who had status epilepticus and for whom EEGs were recorded within 120 h. These included subjects with a final diagnosis of FS (n = 20), epileptic status (ES; n = 11), acute encephalopathy with biphasic seizures and late reduced diffusion (AESD; n = 18), mild encephalopathy with a reversible splenial lesion (MERS; n = 7), other febrile encephalopathies (n = 10), hypoxic-ischemic encephalopathy (n = 1), and intracranial bleeding (n = 1). Initially, all EEGs were visually assessed and graded, and correlation with outcome was explored. Representative EEG epochs were then selected for quantitative analyses. Furthermore, data from AESD (n = 7) and FS (n = 16) patients for whom EEG was recorded within 24 h were also compared. Results Although milder and most severe grades of EEG correlated with neurological outcome, the outcome of moderate EEG severity group was variable and was not predictable from usual inspection. Frequency band analysis revealed that solid delta power was not significantly different among the five groups (AESD, MERS, FS, ES and control), and that MERS group showed the highest theta band power. The ratios of delta/alpha and (delta + theta)/(alpha + beta) band powers were significantly higher in the AESD group than in other groups. The alpha and beta band powers in EEGs within 24 h from onset were significantly lower in the AESD group. The band powers and their ratios showed earlier improvement towards 24 h in FS than in AESD. Conclusion Sequential EEG recording up to 24 h from onset appeared to be helpful for distinction of AESD from FS before emergence of the second phase of AESD. PMID:27046946

    To clarify the molecular changes of sublesional muscle in the acute phase of spinal cord injury (SCI), a moderately severe injury (40 g cm) was induced in the spinal cord (T10 vertebral level) of adult male Sprague-Dawley rats (injury) and compared with sham (laminectomy only). Rats were sacrificed at 48 h (acute) post injury, and gastrocnemius muscles were excised. Morphological examination revealed no significant changes in the muscle fiber diameter between the sham and injury rats. Western blot analyses performed on the visibly red, central portion of the gastrocnemius muscle showed significantly higher expression of muscle specific E3 ubiquitin ligases (muscle ring finger-1 and muscle atrophy f-box) and significantly lower expression of phosphorylated Akt-1/2/3 in the injury group compared to the sham group. Cyclooxygenase 2, tumor necrosis factor alpha (TNF-α), and caspase-1, also had a significantly higher expression in the injury group; although, the mRNA levels of TNF-α and IL-6 did not show any significant difference between the sham and injury groups. These results suggest activation of protein degradation, deactivation of protein synthesis, and development of inflammatory reaction occurring in the sublesional muscles in the acute phase of SCI before overt muscle atrophy is seen.

    2008-01-25

    Fibrinogen-like protein 1 (FGL1) is a hepatocyte derived protein that is upregulated in regenerating rodent livers following partial hepatectomy. It has been implicated as a mitogen for liver cell proliferation. In this study, we show that recombinant human IL-6 induces FGL1 expression in Hep G2 cells in a pattern similar to those of acute phase reactants. Following induction of acute inflammation in rats by subcutaneous injection of turpentine oil, serum FGL1 levels are also enhanced. Although, a recent report suggests that FGL1 associates almost exclusively with the fibrin matrix, we report here that approximately 20% of the total plasma FGL1 remains free. The enhancement of FGL1 levels in vitro by IL-6 and its induction after turpentine oil injection suggest that it is an acute phase reactant. Its presence in bound and free forms in the blood also implies biological roles that extend beyond the proposed autocrine effect it has on hepatocytes during regeneration.

The groups were matched for sex, age and height. Spirometry was measured using a spirometer Microloop Viasys(r) in accordance with American Thoracic Society and European Respiratory Society guidelines. Maximal respiratory pressures were measured with an MVD300 digital manometer (Globalmed(r)). Maximal inspiratory pressures and maximal expiratory pressures were measured from residual volume and total lung capacity, respectively. RESULTS: Group A showed a significant decrease in maximal inspiratory pressures when compared to group B. No significant difference was found between the spirometric values of the two groups, nor was there any difference between maximal inspiratory pressure and maximal expiratory pressure values in group A compared to the lower limit values proposed as reference. CONCLUSION: Children with acute leukemia, myeloid or lymphoid, during the maintenance phase of chemotherapy exhibited unchanged spirometric variables and maximal expiratory pressure; However, there was a decrease in inspiratory muscle strength.

    Background: Intravenous alteplase (rt-PA) remains the only approved treatment for acute ischemic stroke, but its use remains limited. In a previous pilot dose-escalation study, intravenous tenecteplase showed promise as a potentially safer alternative. Therefore, a Phase IIB clinical trial was begun to a) choose a best dose of tenecteplase to carry forward, and b) to provide evidence for either promise or futility of further testing of tenecteplase versus rt-PA. If promise was established, then the trial would continue as a Phase III efficacy trial comparing the selected tenecteplase dose to standard rt-PA. Methods: The trial began as a small, multi-center, randomized, double-blind, controlled clinical trial comparing 0.1, 0.25, and 0.4 mg/kg tenecteplase with standard 0.9 mg/kg rt-PA in patients with acute stroke within 3 hours of onset. An adaptive sequential design used an early (24 hour) assessment of major neurological improvement balanced against occurrence of symptomatic intracranial hemorrhage (ICH) to choose a “best” dose of tenecteplase to carry forward. Once a “best” dose was established, the trial was to continue until at least 100 pairs of the selected tenecteplase dose versus standard rt-PA could be compared by 3 month outcome using the modified Rankin Scale in an interim analysis. Decision rules were devised to yield a clear recommendation to either stop for futility or to continue into Phase III. Results: The trial was prematurely terminated for slow enrollment after only 112 patients had been randomized at 8 clinical centers between 2006 and 2008. The 0.4 mg/kg dose was discarded as inferior after only 73 patients were randomized, but the selection procedure was still unable to distinguish between 0.1 mg/kg and 0.25 mg/kg as a propitious dose at the time the trial was stopped. There were no statistically persuasive differences in 3 month outcomes between the remaining tenecteplase groups and rt-PA. Symptomatic ICH rates were highest in the

    A cohort of 76 patients with acute myocardial infarction was studied with infarct-avid scan, radionuclide ventriculography, and thallium-201 myocardial perfusion scintigraphy. Infarct area, left ventricular ejection fraction, and defect score were calculated as radionuclide indices of the extent of myocardial infarction. The correlation was studied between these indices and cardiac events (death, congestive heart failure, postinfarction angina, and recurrence of myocardial infarction) in the first postinfarction year. High-risk patients (nonsurvivors and patients who developed heart failure) had a larger infarct area, a lower left ventricular ejection fraction, and a larger defect score than the others. Univariate linear discriminant analysis was done to determine the optimal threshold of these parameters for distinguishing high-risk patients from others. Radionuclide parameters obtained in the early phase of acute myocardial infarction were useful for detecting both patients with grave complications and those with poor late prognosis during a mean follow-up period of 2.6 years.

    Purpose: Hypofractionated radiation therapy (RT) in prostate cancer can be developed only if the risk of rectal toxicity is controlled. In a multicenter phase 2 trial, hypofractionated irradiation was combined with an injection of hyaluronic acid (HA) to preserve the rectal wall. Tolerance of the injection and acute toxicity rates are reported. Methods and Materials: The study was designed to assess late grade 2 toxicity rates. The results described here correspond to the secondary objectives. Acute toxicity was defined as occurring during RT or within 3 months after RT and graded according to the Common Terminology Criteria for Adverse Events version 4.0. HA tolerance was evaluated with a visual analog scale during the injection and 30 minutes after injection and then by use of the Common Terminology Criteria at each visit. Results: From 2010 to 2012, 36 patients with low-risk to intermediate-risk prostate cancer were included. The HA injection induced a mean pain score of 4.6/10 ± 2.3. Thirty minutes after the injection, 2 patients still reported pain (2/10 and 3/10), which persisted after the intervention. Thirty-three patients experienced at least 1 acute genitourinary toxicity and 20 patients at least 1 acute gastrointestinal toxicity. Grade 2 toxicities were reported for 19 patients with urinary obstruction, frequency, or both and for 1 patient with proctitis. No grade 3 or 4 toxicities were reported. At the 3-month visit, 4 patients described grade 2 obstruction or frequency, and no patients had any grade 2 gastrointestinal toxicities. Conclusions: The injection of HA makes it possible to deliver hypofractionated irradiation over 4 weeks with a dose per fraction of > 3 Gy, with limited acute rectal toxicity.

    Acute pancreatitis is an acute inflammatory disease of the pancreas, with variable involvement of other regional tissues or remote organ systems. Acute pancreatitis is mild in 80% of cases; virtually all patients with this form of disease will survive, because it's associated with minimal organ dysfunction and uneventful recovery; the severe pancreatitis develops in 20% of cases and is associated with higher morbidity and mortality. It's most important to identify the severity of disease at the moment of hospital admission; many scoring systems have been developed to serve as early prognostic signs: Ranson's criteria, Imrie's criteria, Apache II score, Balthazar's TC score. Recently, new drugs have been proposed in the treatment of acute pancreatitis, as, for example, calcitonine, glucagon, systemic antioxidants, antagonists of the receptors of interleukines, antiproteases (aprotinin and gabexate-mesilate) and the inhibitors of pancreatic secretions (somatostatin and its analogues). However, many controversies still exist concerning the real efficacy of these drugs in the treatment of acute pancreatitis, particularly regarding the inhibitors of pancreatic secretions: recently, some studies showed that somatostatin is able to actually reduce the local complication of the disease and the development of severe forms of acute pancreatitis; on the other hand, other studies failed to show real advantages of somatostatin reducing morbidity and mortality for pancreatitis. The aim of present study is a retrospective analysis of patients affected by acute pancreatitis in order to evaluate efficacy of somatostatin and its analogues. All patients subdivided in two groups: group A, patients treated with conventional therapy plus somatostatin and/or octreotide (SS/LS), and group B, patients treated only with conventional therapy. Results seem to show that somatostatin does not positively affect morbidity and mortality in patients with acute pancreatitis. The Authors conclude

    We report the case of a patient with narrow angles who had an attack of bilateral acute angle-closure glaucoma precipitated by dexfenfluramine, a serotoninergic drug developed for appetite suppression. Although the exact mechanism remains uncertain, the pupillary block observed in our case may be the result of the serotoninergic or indirect parasympatholytic properties of the drug on the iris sphincter muscle. Serotonergic psychoactive drugs should be prescribed cautiously in patients with known narrow angles and should be monitored by an ophthalmologist.

    Suppression of apoptosis by TP53 mutation contributes to resistance of acute myeloid leukemia (AML) to conventional cytotoxic treatment. Using differentiation to induce irreversible cell cycle exit in AML cells could be a p53-independent treatment alternative, however, this possibility requires evaluation. In vitro and in vivo regimens of the deoxycytidine analogue decitabine that deplete the chromatin modifying enzyme DNA methyl-transferase 1 (DNMT1) without phosphorylating p53 or inducing early apoptosis were determined. These decitabine regimens but not equimolar DNA-damaging cytarabine up regulated the key late differentiation factors CEBPε and p27/CDKN1B, induced cellular differentiation, and terminated AML cell-cycle, even in cytarabine-resistant p53- and p16/CDKN2A-null AML cells. Leukemia initiation by xeno-transplanted AML cells was abrogated but normal hematopoietic stem cell (HSC) engraftment was preserved. In vivo, the low toxicity allowed frequent drug administration to increase exposure, an important consideration for S-phase specific decitabine therapy. In xeno-transplant models of p53-null and relapsed/refractory AML, the non-cytotoxic regimen significantly extended survival compared to conventional cytotoxic cytarabine. Modifying in vivo dose and schedule to emphasize this pathway of decitabine action can bypass a mechanism of resistance to standard therapy. PMID:21701495

    Acute and subacute ischemia of the legs in acute and subacute femoropopliteal bypass occlusion is a dramatic situation that endangers the survival of the limbs, depending on the severity of the ischemia. Different therapy options like percutaneous mechanical thrombectomy procedures, which include rotational thrombectomy, have become available in recent years, in addition to local lysis and surgical thrombectomy. Surgical thrombectomy using the Fogarty catheter technique, in particular, shows an increased incidence of perioperative complications but only small technical success rates in randomized trials. On the other hand, local lysis is associated with increased costs due to resource-consuming measures, such as intensive monitoring and repeat angiographies, in addition to bleeding complications. In the past, further development of the Straub Rotarex® system as an endovascular therapy option has demonstrated good success leading to amputation-free survival in multiple studies. At the same time, a low rate of complications with use has been documented. Most examinations have been conducted in the thigh. To date, there are little investigational data on its use in acutely and subacutely occluded femoropopliteal bypasses. In this paper, the current study-based significance of the Rotarex system for this indication is analyzed based on the existing literature and the authors’ own experiences with 22 patients.

    1993-06-01

    We report our clinical experience with a group of 14 patients who presented with acute myocardial infarction. A holmium:YAG laser was applied to the infarct-related artery. This laser emits 250 - 600 mJ per pulse, with a pulse length of 250 microseconds and repetition rate of 5 Hz. Potential benefits of acute thrombolysis by lasers include the absence of systemic lytic state; a shortened thrombus clearing time relative to using thrombolytics; safe removal of the intracoronary thrombus and facilitation of adjunct balloon angioplasty. Potential clinical difficulties include targeting the obstructive clot and plaque, creation of debris and distal emboli and laser-tissue damage. It is conceivable that holmium:YAG laser can be a successful thrombolytic device as its wave length (2.1 microns) coincides with strong water absorption peaks. Since it is common to find an atherosclerotic plaque located under or distal to the thrombotic occlusion, this laser can also be applied for plaque ablation, and the patient presenting with acute myocardial infarction can clearly benefit from the combined function of this laser system.

    Background Ocular manifestations of the dengue fever virus include bilateral panuveitis that can occur after the acute systemic infection has resolved. In most reported cases, the inflammation resolves with topical or systemic steroid therapy. We report a case of chronic, refractory bilateral panuveitis and uveitic glaucoma that began during the acute phase of the systemic infection and required treatment with oral steroids, multiple steroid-sparing agents, and surgical therapy for glaucoma. Findings A 22-year-old male with acute systemic dengue fever presented with bilateral pain and decreased vision. Clinical examination revealed bilateral panuveitis with elevated intraocular pressures. Management required oral steroids, mycophenolate mofetil, cyclosporine, and bilateral glaucoma valve implantation. Conclusion This case highlights the fact that dengue-associated panuveitis can begin in the acute stage of systemic infection and persist long after convalescence with progression to chronic bilateral panuveitis and uveitic glaucoma. Dengue-associated chronic panuveitis with uveitic glaucoma may be effectively managed with a combination of steroid-sparing oral immunosuppression and glaucoma surgery. This is, to our knowledge, the first case of bilateral refractory dengue-associated panuveitis from the Caribbean treated with combination steroid-sparing oral immunosuppression and bilateral glaucoma valve implantation.

    The present study aimed to investigate the diagnostic and prognostic importance of oxidative stress biomarkers and acute phase proteins in urinary tract infection (UTI) in camels. We describe the clinical, bacteriological and biochemical findings in 89 camels. Blood and urine samples from diseased (n = 74) and control camels (n = 15) were submitted to laboratory investigations. The urine analysis revealed high number of RBCS and pus cells. The concentrations of serum and erythrocytic malondialdehyde (sMDA & eMDA), Haptoglobin (Hp), serum amyloid A (SAA), Ceruloplasmin (Cp), fibrinogen (Fb), albumin, globulin and interleukin 6 (IL-6) were higher in diseased camels when compared to healthy ones. Catalase, super oxide dismutase and glutathione levels were lower in diseased camels when compared with control group. Forty one of 74 camels with UTI were successfully treated. The levels of malondialdehyde, catalase, super oxide dismutase, glutathione, Hp, SAA, Fb, total protein, globulin and IL-6 were associated with the odds of treatment failure. The MDA showed a great sensitivity (Se) and specificity (Sp) in predicting treatment failure (Se 85%/Sp 100%) as well as the SAA (Se 92%/Sp 87%) and globulin levels (Se 85%/Sp 100%) when using the cutoffs that maximizes the sum of Se + Sp. Multivariate logistic regression analysis revealed that two models had a high accuracy to predict failure with the first model including sex, sMDA and Hp as covariates (area under the receiver operating characteristic curve (AUC) = 0.92) and a second model using sex, SAA and Hp (AUC = 0.89). Conclusively, the oxidative stress biomarkers and acute phase proteins could be used as diagnostic and prognostic biomarkers in camel UTI management. Efforts should be forced to investigate such biomarkers in other species with UTI. PMID:26587339

    Identification of biomarkers assists in the diagnosis of disease and the assessment of health risks from environmental exposures. We hypothesized that rats exposed to Libby amphibole (LA) would present with a unique serum proteomic profile which could help elucidate epidemiologically-relevant biomarkers. In four experiments spanning varied protocols and temporality, healthy (Wistar Kyoto, WKY; and F344) and cardiovascular compromised (CVD) rat models (spontaneously hypertensive, SH; and SH heart failure, SHHF) were intratracheally instilled with saline (control) or LA. Serum biomarkers of cancer, inflammation, metabolic syndrome (MetS), and the acute phase response (APR) were analyzed. All rat strains exhibited acute increases in α-2-macroglobulin, and α1-acid glycoprotein. Among markers of inflammation, lipocalin-2 was induced in WKY, SH and SHHF and osteopontin only in WKY after LA exposure. While rat strain- and age-related changes were apparent in MetS biomarkers, no LA effects were evident. The cancer marker mesothelin was increased only slightly at 1 month in WKY in one of the studies. Quantitative Intact Proteomic profiling of WKY serum at 1 day or 4 weeks after 4 weekly LA instillations indicated no oxidative protein modifications, however APR proteins were significantly increased. Those included serine protease inhibitor, apolipoprotein E, α-2-HS-glycoprotein, t-kininogen 1 and 2, ceruloplasmin, vitamin D binding protein, serum amyloid P, and more 1 day after last LA exposure. All changes were reversible after a short recovery regardless of the acute or long-term exposures. Thus, LA exposure induces an APR and systemic inflammatory biomarkers that could have implications in systemic and pulmonary disease in individuals exposed to LA. -- Highlights: ► Biomarkers of asbestos exposure are required for disease diagnosis. ► Libby amphibole exposure is associated with increased human mortality. ► Libby amphibole increases circulating proteins involved

    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.

    Peculiarities of clinical course, diagnosis and treatment of elderly patients for an acute pancreatitis were analyzed. There was established, that the clinical course of an acute pancreatitis is atypical with obscure symptoms. Late admittance to hospital, presence of concomitant diseases, low reactivity of the organism defense systems, morpho-functional changes in pancreatic gland complicate the early diagnosis. While the abdominal pain occurrence in the patient it is necessary always to keep in mind the diagnosis of an acute pancreatitis and not to rely on the diagnosis with which the patient was delivered to hospital. Because of presence of several concomitant diseases in a patient with an acute pancreatitis the treatment must be multimodal with multidisciplinary approach, including surgeon, anesthesiologist and therapeutist. Operative intervention is mandatory only in presence of a life-threatening complications and in insufficiency of conservative therapy. Miniinvasive technologies constitute the first-line procedures.

    Acute myelogenous leukemia is a heterogeneous disease. Recent molecular mutational analysis techniques have shed more light on different, genetically well characterised types of the disease. Treatment approach is uniform except for acute promyelocytic leukemia. Application of the "3 + 7" induction treatment has been the gold standard in the past 40 years. While the dose of cytarabine has not been changed, escalating daunorubicine dose in younger (<60 years) patients with good performance status to 90 mg/m(2) had a positive impact on overall survival. High dose chemotherapy is tolerated poorly in patients older than 60 years of age and, as treatment is not curative in the elderly, improvement of overall survival and quality of life remains the main goal of management in these patients. Low intensity treatment is beneficial and can provide additional advantage over supportive care. Innovative and targeted therapy approaches might give promise to better management of patients with acute myelogenous leukemia.

    Using nuclear isotopic imaging, digital circulation was sequentially evaluated at 24-hour intervals in 11 control horses and in 9 horses affected with acute laminitis, created by administration of a high-starch ration. Following intra-arterial injection of /sup 99m/Tc macroaggregated albumin into the brachiocephalic trunk, a gamma camera and dedicated nuclear medicine computer were used to acquire static images of the right front foot. Dynamic vascular-phase and static interstitial-phase images were also obtained after jugular vein injection of /sup 99m/Tc diethylenetriamine pentaacetic acid. These procedures were performed on standing horses, using either minimal or no tranquilization. The images were quantitatively analyzed for parameters indicative of circulation to the foot as a whole and to specific regions of interest within the foot. There was no evidence of reduced total blood flow to the lamellae during either the developmental or acute phases of laminitis. Although total flow tended to increase throughout the peripheral/external regions of the foot, statistically significant elevations were consistently present only within the lamellae. Changes indicative of decreased total blood flow were noted in the central/internal regions of the foot. These alterations usually occurred coincident with or after the onset of clinical lameness.

One goal of the workshop was to establish a roadmap to building an evidence base on that would indicate whether acupuncture is helpful for treating active-duty military personnel experiencing acute pain. The workshop highlighted brief presentations on the most current research on acupuncture and acute pain mechanisms. The impact of various modifiers (stress, genetics, population, phenotypes, etc.) on acute pain pathways and response to acupuncture treatment was discussed. Additional presentations focused on common neural mechanisms, an overview of real-world experience with using acupuncture to treat traumatic acute pain, and best tools and methods specific for acupuncture studies. Three breakout groups addressed the gaps, opportunities, and barriers to acupuncture use for acute pain in military and trauma settings. Different models of effectiveness research and optimal research designs for conducting trials in acute traumatic pain were also discussed. PMID:23020611

    Purpose: To report the acute toxicity profile and compliance from a randomized Phase III trial comparing accelerated radiotherapy (AR) with accelerated radiotherapy plus carbogen and nicotinamide (ARCON) in laryngeal cancer. Methods and Materials: From April 2001 to February 2008, 345 patients with cT2-4 squamous cell laryngeal cancer were randomized to AR (n = 174) and ARCON (n = 171). Acute toxicity was scored weekly until Week 8 and every 2-4 weeks thereafter. Compliance to carbogen and nicotinamide was reported. Results: Between both treatment arms (AR vs. ARCON) no statistically significant difference was observed for incidence of acute skin reactions (moist desquamation: 56% vs. 58%, p = 0.80), acute mucosal reactions (confluent mucositis: 79% vs. 85%, p = 0.14), and symptoms related to acute mucositis (severe pain on swallowing: 53% vs. 58%, p = 0.37; nasogastric tube feeding: 28% vs. 28%, p = 0.98; narcotic medicines required: 58% vs. 58%, p = 0.97). There was a statistically significant difference in median duration of confluent mucositis in favor of AR (2.0 vs 3.0 weeks, p = 0.01). There was full compliance with carbogen breathing and nicotinamide in 86% and 80% of the patients, with discontinuation in 6% and 12%, respectively. Adjustment of antiemesis prophylaxis was needed in 42% of patients. Conclusion: With the exception of a slight increase in median duration of acute confluent mucositis, the present data reveal a similar acute toxicity profile between both regimens and a good compliance with ARCON for clinical stage T2-4 laryngeal cancers. Treatment outcome and late morbidity will determine the real therapeutic benefit.

    Oral capecitabine is a prodrug of 5-fluorouracil that has been used into the management of multiple cancers because of the convenience of administration and efficacy at least comparable with 5-fluorouracil. While cardiac complications associated with the use of 5-fluorouracil are well-documented, capecitabine-induced acute coronary syndrome has rarely been reported and often attributed to coronary vasospasm.

    To review the evidence of thromboembolism incidence and prophylaxis in the sub-acute phase of spinal cord injury (SCI) 3–6 months post injury. All observational and experimental studies with any length of follow-up and no limitations on language or publication status published up to March 2015 were included. Two review authors independently selected trials for inclusion and extracted data. Outcomes studied were incidence of pulmonary embolism (PE) and deep vein thrombosis (DVT) in the sub-acute phase of SCI. The secondary outcome was type of thromboprophylaxis. Our search identified 4305 references and seven articles that met the inclusion criteria. Five papers reported PE events and three papers reported DVT events in the sub-acute phase of SCI. Studies were heterogeneous in populations, design and outcome reporting, therefore a meta-analysis was not performed. The included studies report a PE incidence of 0.5%–6.0% and DVT incidence of 2.0%–8.0% in the sub-acute phase of SCI. Thromboprophylaxis was poorly reported. Spinal patients continue to have a significant risk of PE and DVT after the acute period of their injury. Clinicians are advised to have a low threshold for suspecting venous thromboembolism in the sub-acute phase of SCI and to continue prophylactic anticoagulation therapy for a longer period of time.

    Purpose Transient global amnesia (TGA) is a transitory, short-lasting neurological disorder characterized by a sudden onset of antero- and retrograde amnesia. Perfusion abnormalities in TGA have been evaluated mainly by use of positron emission tomography (PET) or single-photon emission computed tomography (SPECT). In the present study we explore the value of dynamic susceptibility contrast perfusion-weighted MRI (PWI) in TGA in the acute phase. Methods From a MRI report database we identified TGA patients who underwent MRI including PWI in the acute phase and compared these to control subjects. Quantitative perfusion maps (cerebral blood flow (CBF) and volume (CBV)) were generated and analyzed by use of Signal Processing In NMR-Software (SPIN). CBF and CBV values in subcortical brain regions were assessed by use of VOI created in FIRST, a model-based segmentation tool in the Oxford Centre for Functional Magnetic Resonance Imaging of the Brain (FMRIB) Software Library (FSL). Results Five TGA patients were included (2 men, 3 women). On PWI, no relevant perfusion alterations were found by visual inspection in TGA patients. Group comparisons for possible differences between TGA patients and control subjects showed significant lower rCBF values bilaterally in the hippocampus, in the left thalamus and globus pallidus as well as bilaterally in the putamen and the left caudate nucleus. Correspondingly, significant lower rCBV values were observed bilaterally in the hippocampus and the putamen as well as in the left caudate nucleus. Group comparisons for possible side differences in rCBF and rCBV values in TGA patients revealed a significant lower rCBV value in the left caudate nucleus. Conclusions Mere visual inspection of PWI is not sufficient for the assessment of perfusion changes in TGA in the acute phase. Group comparisons with healthy control subjects might be useful to detect subtle perfusion changes on PWI in TGA patients. However, this should be confirmed in

    Migratory birds have been implicated in the spread of some zoonotic diseases, but how well infected individuals can fly remains poorly understood. We used western sandpipers, Calidris mauri, to experimentally test whether flight is affected when long-distance migrants are mounting an immune response and whether migrants maintain immune defences during a flight in a wind tunnel. We measured five indicators of innate immunity in 'flown-healthy' birds (flying in a wind tunnel without mounting an immune response), 'flown-sick' birds (flying while mounting an acute phase response, which is part of induced innate immunity), and a non-flying control group ('not-flown'). Voluntary flight duration did not differ between flown-healthy and flown-sick birds, indicating that mounting an acute phase response to simulated infection did not hamper an individual's ability to fly for up to 3 h. However, in comparison to not-flown birds, bacterial killing ability of plasma was significantly reduced after flight in flown-sick birds. In flown-healthy birds, voluntary flight duration was positively correlated with bacterial killing ability and baseline haptoglobin concentration of the blood plasma measured 1-3 weeks before experimental flights, suggesting that high quality birds had strong immune systems and greater flight capacity. Our findings indicate that flight performance is not diminished by prior immune challenge, but that flight while mounting an acute phase response negatively affects other aspects of immune function. These findings have important implications for our understanding of the transmission of avian diseases, as they suggest that birds can still migrate while fighting an infection.

    A 42-kDa protein appeared at a much higher concentration in plasma from Trypanosoma brucei-resistant (C57BL/6) mice after infection than in plasma from trypanosome-susceptible (C3H/He) mice. This protein was purified by sequential steps of gel filtration, protein A-Sepharose affinity chromatography, isoelectric focusing, and ammonium sulfate precipitation. The purified protein was identified as a subunit of the acute-phase reactant haptoglobin. Causes of elevated plasma haptoglobin and its implications for resistance to trypanosomiasis are discussed.

    Hematological malignancies present abnormal blood cells that may have altered functions. This study aimed to evaluate nutritional status, acute phase proteins, parameters of cell's functionality, and oxidative stress of patients with hematological malignancies, providing a representation of these variables at diagnosis, comparisons between leukemias and lymphomas and establishing correlations. Nutritional status, C-reactive protein (CRP), albumin, phagocytic capacity and superoxide anion production of mononuclear cells, lipid peroxidation and catalase activity in plasma were evaluated in 16 untreated subjects. Main diagnosis was acute leukemia (n = 9) and median body mass index (BMI) indicated overweight (25.6 kg/m(2)). Median albumin was below (3.2 g/dL) and CRP above (37.45 mg/L) the reference values. Albumin was inversely correlated with BMI (r = -0.53). Most patients were overweight before the beginning of treatment and had a high CRP/albumin ratio, which may indicate a nutrition inflammatory risk. BMI values correlated positively with lipid peroxidation and catalase activity. A strong correlation between catalase activity and lipid peroxidation was found (r = 0.75). Besides the elevated BMI, these patients also have elevated CRP values and unexpected relations between nutritional status and albumin, reinforcing the need for nutritional counseling during the course of chemotherapy, especially considering the correlations between oxidative stress parameters and nutritional status evidenced here.

    We studied 35 patients meeting DSM-III criteria for schizophrenia, paranoid or undifferentiated type, chronic with acute exacerbation. All were treated in hospital, 13 on a psychiatric intensive care unit, and 22 on an open ward. The former unit is a more structured and less stimulating one. We found those patients treated on that ward to show greater improvement in BPRS ratings during the first 2 days of hospitalization compared to the open-ward group, despite similar doses of medication being utilized. Additionally, this improvement was noted to occur among BPRS items comprising a psychotic subscale.

    Acute adrenal haemorrhage (AAH) is a rare disorder with different aetiologies. Aiming to discuss this condition, this report deals with four different cases that will be analysed and examined below, each one of them confirmed by biopsy or surgery and followed clinically and radiologically. In these cases it was found that the patients suffered from localized abdominal pain (4/4) and fever (2/4); one patient had adrenal insufficiency due to bilateral massive AAH. Therefore we concluded that AAH is an uncommon condition with variable clinical manifestations. PMID:9089038

    The mixed dentition is the developmental period after the permanent first molars and incisors have erupted, and before the remaining deciduous teeth are lost. Phase I treatment is usually done early in this period. Mixed dentition treatment goals often focus on skeletal rather than dental correction. To design a treatment plan, the clinician must understand the growth and development patterns, and the known effects of the chosen treatment modality. Jaw growth affects orthodontic treatment, usually favorably, but sometimes unfavorably. When and how much growth will occur is completely unpredictable. However, we know some useful facts about jaw growth in the mixed dentition. The two areas that remain controversial in the orthodontic literature are the treatment of crowding and of Class II malocclusions in the mixed dentition. Is there a benefit to early treatment for these problems? This question has yet to be fully answered by researchers. Hence, we planned for review of all available literature to come to a consensus about preventive or interceptive orthodontics or in other words Phase 1 and Phase 2 treatment. The clinician can diagnose and intercept certain developing problems with early treatment. Many other cases should be supervised, but not treated until the permanent teeth are in place. We must base our decision to treat on experience, knowledge of growth and dental development, and research.

    A double-blind, placebo-controlled, randomized (simple randomisation), pilot (phase III) study of Chisan, (ADAPT-232; a standardised fixed combination of extracts of Rhodiola rosea L., Schisandra chinensis Turcz. Baill., and Eleutherococcus senticosus Maxim) was carried out on two parallel groups of patients suffering from acute nonspecific pneumonia. Sixty patients (males and females; 18-65 years old) received a standard treatment with cephazoline, bromhexine, and theophylline: in addition, one group of 30 patients was given Chisan mixture, whilst the second group of 30 patients received a placebo, each medication being taken twice daily from the beginning of the study for 10-15 days. The primary outcome measurements were the duration of antibiotic therapy associated with the clinical manifestations of the acute phase of the disease, together with an evaluation of mental performance in a psychometric test and the self-evaluation of quality-of-life (QOL) (WHOQOL-Bref questionnaires) before treatment and on the first and fifth days after clinical convalescence. The mean duration of treatment with antibiotics required to bring about recovery from the acute phase of the disease was 2 days shorter in patients treated with Chisan compared with those in the placebo group. With respect to all QOL domains (physical, psychological, social and ecological), patients in the Chisan group scored higher at the beginning of the rehabilitation period, and significantly higher on the fifth day after clinical convalescence, than patients in the control group. Clearly, adjuvant therapy with ADAPT-232 has a positive effect on the recovery of patients by decreasing the duration of the acute phase of the illness, by increasing mental performance of patients in the rehabilitation period, and by improving their QOL. Both the clinical and laboratory results of the present study suggest that Chisan (ADAPT-232) can be recommended in the standard treatment of patients with acute non

  4. Lack of association of acute phase response proteins with hormone levels and antidepressant medication in perimenopausal depression

    2014-01-01

    Background Major depression is associated with higher plasma levels of positive acute-phase proteins, as well as with lower plasma levels of negative acute-phase proteins. The aim of this study is to examine the levels of acute-phase response proteins and whether these levels are influenced by reproductive hormones and antidepressant medication in the perimenopausal depression. Methods Sixty-five women (age range: 40–58 years old) participated in this study. All women were in the perimenopausal phase. The diagnosis of depression was made through a psychiatric interview and with the aid of Hamilton Depression Rating Scale 17 (HAM-D 17). The acute-phase response proteins, such as haptoglobin (HP), transferrine (TRf), α1-antitrypsin, complement protein 3 (C3), complement protein 4 (C4) and C-reactive protein (CRP) and the reproductive hormones, for example follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2), were analyzed using standard laboratory methods. Pearson’s correlations were applied to evaluate the relationship between acute-phase proteins and hormones. Results Perimenopausal women were divided into three groups. The first group consisted of normal controls, the second one involved depressed perimenopausal women, who were taking selective serotonin reuptake inhibitors (SSRIs), and the third one included depressed women that were not treated with SSRIs. Depressed women in perimenopause, when being compared to non-depressed women, did not differ as to serum levels of acute-phase proteins. There was a positive correlation between HP and E2 in depressed perimenopausal women, who were not taking SSRIs. Conclusions The lack of association between acute-phase proteins and depressive mood mentioned in this study does not support previous findings in patients with major depression. This negative finding in perimenopausal depression indicates either the absence or a more complex nature of the interactions between acute-phase proteins

    This article presents the results of treatment of 54 patients with acute pancreatitis. The patients were divided into two groups according to the method of treatment. The control group (26 patients) received a conventional therapy, whereas the experimental group (28 patients) received mexidol in combination with the intravenous laser irradiation of blood. Clinical and laboratory tests confirmed a high efficiency of the combined therapy based on the administration of mexidol antioxidant and low-intensity (lambda) equals 0.63 micrometers diode laser irradiation of blood. This therapeutic technique produced an influence on the basic pathogenetic mechanisms of acute pancreatitis. The application of this method of treatment improved the course and prognosis of acute pancreatitis.

    Zika virus is an emerging mosquito-borne flavivirus currently causing large epidemics in the Pacific Ocean region and Brazil. Clinically, Zika fever resembles dengue fever, but is less severe. Whereas the clinical syndrome and laboratory diagnostic procedures have been described, little attention was paid to the immunology of the disease and its possible use for clinical follow-up of patients. Here, we investigate the role of cytokines in the pathogenesis of Zika fever in travelers returning from Asia, the Pacific, and Brazil. Polyfunctional T cell activation (Th1, Th2, Th9, and Th17 response) was seen during the acute phase characterized by respective cytokine level increases, followed by a decrease in the reconvalescent phase.

    OBJECTIVE: This is an analysis of the unpublished continuation phase of Study 329, the primary objective of which was to compare the efficacy and safety of paroxetine and imipramine with placebo in the treatment of adolescents with unipolar major depression. The objectives of the continuation phase were to assess safety and relapse rates in the longer term. The objective of this publication, under the Restoring Invisible and Abandoned Trials (RIAT) initiative, was to see whether access to and analysis of the previously unpublished dataset from the continuation phase of this randomized controlled trial would have clinically relevant implications for evidence-based medicine. METHODS: The study was an eight-week double-blind randomized placebo-controlled trial with a six month continuation phase. The setting was 12 North American academic psychiatry centres, from 20 April 1994 to 15 February 1998. 275 adolescents with major depression were originally enrolled in Study 329, with 190 completing the eight-week acute phase. Of these, 119 patients (43%) entered the six-month continuation phase (paroxetine n = 49; imipramine n = 39; placebo n = 31), in which participants were continued on their current treatment, blinded. As per the protocol, we have looked at rates of relapse (based on Hamilton Depression Scale scores) across both acute and continuation phases, and generated a safety profile for paroxetine and imipramine compared with placebo for up to six months. ANOVA testing (generalized linear model) using a model including effects of site, treatment and site x treatment interaction was applied. Otherwise we used only descriptive statistics. RESULTS: Of patients entering the continuation phase, 15 of 49 for paroxetine (31%), 12 of 39 for imipramine (31%) and 12 of 31 for placebo (39%) completed as responders. Across the study, 25 patients on paroxetine relapsed (41% of those showing an initial response), 15 on imipramine (26%), and 10 on placebo (21%). In

    Objective. Assess impact of Medicare Part D benefit phases on adherence with evidence-based medications after hospitalization for an acute myocardial infarction. Data Source. Random 5 percent sample of Medicare beneficiaries. Study Design. Difference-in-difference analysis of drug adherence by AMI patients stratified by low-income subsidy (LIS) status and benefit phase. Data Collection/Extraction Methods. Subjects were identified with an AMI diagnosis in Medicare Part A files between April 2006 and December 2007 and followed until December 2008 or death (N = 8,900). Adherence was measured as percent of days covered (PDC) per month with four drug classes used in AMI treatment: angiotensin-converting enzyme (ACE) inhibitors/angiotensin II receptor blockers (ARBs), beta-blockers, statins, and clopidogrel. Monthly exposure to Part D benefit phases was calculated from flags on each Part D claim. Principal Findings. For non-LIS enrollees, transitioning from the initial coverage phase into the Part D coverage gap was associated with statistically significant reductions in mean PDC for all four drug classes: statins (−7.8 percent), clopidogrel (−7.0 percent), beta-blockers (−5.9 percent), and ACE inhibitor/ARBs (−5.1 percent). There were no significant changes in adherence associated with transitioning from the gap to the catastrophic coverage phase. Conclusions. As the Part D doughnut hole is gradually filled in by 2020, Medicare Part D enrollees with critical diseases such as AMI who rely heavily on brand name drugs are likely to exhibit modest increases in adherence. Those reliant on generic drugs are less likely to be affected. PMID:23742013

    Women often exhibit larger hormonal and subjective responses to opioid receptor antagonists than men, but the biological mechanisms mediating this effect remain unclear. Among women, fluctuations in estradiol (E2) and progesterone (P4) across the menstrual cycle (MC) affect the endogenous opioid system. Therefore, the goal of the current study was to compare acute naltrexone response between women in the early follicular phase of the MC (low E2 and P4), women in the luteal phase of the MC (high E2 and P4), and men. Seventy healthy controls (n = 46 women) participated in two morning sessions in which they received 50 mg naltrexone or placebo in a randomized, counterbalanced order. Women were randomized to complete both sessions in either the early follicular (n = 23) or luteal phase of the MC. Serum cortisol, prolactin, and luteinizing hormone (LH), salivary cortisol, and subjective response were assessed upon arrival to the laboratory and at regular intervals after pill administration. In luteal and early follicular women but not men, naltrexone (vs. placebo) increased serum cortisol and prolactin levels from baseline; however, the naltrexone-induced increases in these hormones were significantly greater in luteal women than early follicular women. Additionally, only luteal women demonstrated an increase from baseline in salivary cortisol levels and the severity of adverse drug effects in response to naltrexone. In sum, the results indicate that luteal phase women are more sensitive to acute hormonal and subjective effects of naltrexone than early follicular women and men. These findings may have important implications for the use of naltrexone in women. PMID:25459893

    The aim of this study was to determine whether Saccharomyces boulardii prevents and treats diarrhoea and antibiotic-associated diarrhoea (AAD) in children. A total of 333 hospitalised children with acute lower respiratory tract infection were enrolled in a 2-phase open randomised controlled trial. During the 1st phase, all children received intravenous antibiotics (AB). They were randomly allocated to group A (S. boulardii 500 mg/day + AB, n=167) or group B (AB alone, n=166) and followed for 2 weeks. Diarrhoea was defined as ≥3 loose/watery stools/day during at least 2 days, occurring during treatment and/or up to 2 weeks after AB therapy had stopped. AAD was considered when diarrhoea was caused by Clostridium difficile or when stool cultures remained negative. In the 2nd phase of the study, group B patients who developed diarrhoea were randomly allocated to two sub-groups: group B1 (S. boulardii + oral rehydration solution (ORS)) and group B2 (ORS alone). Data from 283 patients were available for analysis. Diarrhoea prevalence was lower in group A than in group B (11/139 (7.9%) vs. 42/144 (29.2%); relative risk (RR): 0.27, 95% confidence interval (CI): 0.1-0.5). S. boulardii reduced the risk of AAD (6/139 (4.3%) vs. 28/144 (19.4%); RR: 0.22; 95% CI: 0.1-0.5). When group B patients developed diarrhoea (n=42), S. boulardii treatment during 5 days (group B1) resulted in lower stool frequency (P<0.05) and higher recovery rate (91.3% in group B1 vs. 21.1% in B2; P<0.001). The mean duration of diarrhoea in group B1 was shorter (2.31±0.95 vs. 8.97±1.07 days; P<0.001). No adverse effects related to S. boulardii were observed. S. boulardii appeared to be effective in the prevention and treatment of diarrhoea and AAD in children treated with intravenous antibiotics.

    Compartment syndrome of the thigh is a rare emergency often treated operatively. The purpose of this study was to evaluate the effects of nonoperative treatment for compartment syndrome of the thigh associated with acute renal failure after the 2008 Wenchuan earthquake. Nonoperative treatment, which primarily involves continuous renal replacement therapy, was performed in 6 patients (3 men and 3 women) who presented with compartment syndrome of the thigh associated with acute renal failure. The mean mangled extremity severity score (MESS) and laboratory data regarding renal function were analyzed before and after treatment, and the clinical outcome was evaluated at 17-month follow-up. Laboratory data regarding renal function showed improvements. All 6 patients survived with the affected lower limbs intact after nonoperative treatment. Follow-up revealed active knee range of motion and increased muscle strength, as well as a recovery of sensation. A positive linear correlation was found between MESS and the time required to achieve a reduction in swelling, as well as the time required for the recovery of sensation and knee range of motion (r>0.8; P<.05). Satisfactory clinical outcomes were obtained in patients with compartment syndrome of the thigh associated with acute renal failure.Urine alkalization, electrolyte and water balance, and continuous renal replacement therapy have played an important role in saving lives and extremities. Nonoperative treatment should be considered in the treatment of compartment syndrome of the thigh associated with acute renal failure. PMID:22495847

    Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis, asparaginase-associated pancreatitis, arterial hypertension, posterior reversible encephalopathy syndrome, seizures, depressed level of consciousness, methotrexate-related stroke-like syndrome, peripheral neuropathy, high-dose methotrexate-related nephrotoxicity, sinusoidal obstructive syndrome, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment. Our results showed that none of the protocols addressed all 14 toxic effects, that no two protocols shared identical definitions of all toxic effects, and that no toxic effect definition was shared by all protocols. Using the Delphi method over three face-to-face plenary meetings, consensus definitions were obtained for all 14 toxic effects. In the overall assessment of outcome of acute lymphoblastic leukaemia treatment, these expert opinion-based definitions will allow reliable comparisons of frequencies and severities of acute toxic effects across treatment protocols, and facilitate international research on cause, guidelines for treatment adaptation, preventive strategies, and development of consensus algorithms for reporting on acute lymphoblastic leukaemia treatment.

    Infection of Asian elephants (Elephas maximus) with elephant endotheliotropic herpesvirus (EEHV) can be associated with rapid, lethal hemorrhagic disease and has been documented in elephant herds in human care and in the wild. Recent reports describe real-time quantitative polymerase chain reaction (qPCR) assays used to monitor clinically ill elephants and also to detect subclinical EEHV1 infection in apparently healthy Asian elephants. Acute phase proteins have been demonstrated to increase with a variety of infectious etiologies in domesticated mammals but have not yet been described in elephants. In addition, the immune response of Asian elephants to EEHV1 infection has not been described. In this study, whole blood and trunk wash samples representing repeated measures from eight elephants were examined for the presence of EEHV1 using a qPCR assay. Elephants were classified into groups, as follows: whole blood negative and positive and trunk wash negative and positive. Serum amyloid A (SAA) and haptoglobin (HP) levels were compared between these groups. A significant difference in SAA was observed with nearly a threefold higher mean value during periods of viremia (P=0.011). Higher values of SAA were associated with >10,000 virus genome copies/ml EEHV1 in whole blood. There were no significant differences in HP levels, although some individual animals did exhibit increased levels with infection. These data indicate that an inflammatory process is stimulated during EEHV1 viremia. Acute phase protein quantitation may aid in monitoring the health status of Asian elephants.

  15. HIV infection and drugs of abuse: role of acute phase proteins

    PubMed Central

    2013-01-01

    Background HIV infection and drugs of abuse such as methamphetamine (METH), cocaine, and alcohol use have been identified as risk factors for triggering inflammation. Acute phase proteins such as C-reactive protein (CRP) and serum amyloid A (SAA) are the biomarkers of inflammation. Hence, the interactive effect of drugs of abuse with acute phase proteins in HIV-positive subjects was investigated. Methods Plasma samples were utilized from 75 subjects with METH use, cocaine use, alcohol use, and HIV-positive alone and HIV-positive METH, cocaine, and alcohol users, and age-matched control subjects. The plasma CRP and SAA levels were measured by ELISA and western blot respectively and the CD4 counts were also measured. Results Observed results indicated that the CRP and SAA levels in HIV-positive subjects who are METH, cocaine and alcohol users were significantly higher when compared with either drugs of abuse or HIV-positive alone. The CD4 counts were also dramatically reduced in HIV-positive with drugs of abuse subjects compared with only HIV-positive subjects. Conclusions These results suggest that, in HIV-positive subjects, drugs of abuse increase the levels of CRP and SAA, which may impact on the HIV infection and disease progression. PMID:24044608

    The orphan nuclear receptor liver receptor homolog 1 (LRH-1) has been reported to play an important role in bile acid biosynthesis and reverse cholesterol transport. Here, we show that LRH-1 is a key player in the control of the hepatic acute-phase response. Ectopic expression of LRH-1 with adenovirus resulted in strong inhibition of both interleukin-6 (IL-6)- and IL-1beta-stimulated haptoglobin, serum amyloid A, and fibrinogen beta gene expression in hepatocytes. Furthermore, induction of the hepatic inflammatory response was significantly exacerbated in HepG2 cells expressing short hairpin RNA targeting LRH-1 expression. Moreover, transient-transfection experiments and electrophoretic mobility shift and chromatin immunoprecipitation assays revealed that LRH-1 regulates this cytokine-elicited inflammatory response by, at least in part, antagonizing the CCAAT/enhancer binding protein beta signaling pathway. Finally, we show, by using LRH-1 heterozygous mice, that LRH-1 is involved in the control of the inflammatory response at the hepatic level in vivo. Taken together, our results outline an unexpected role for LRH-1 in the modulation of the hepatic acute-phase response.

    The extent of inflammation associated with tail biting in finishing pigs was evaluated. Tail histopathology, carcass condemnation and the concentration of three acute phase proteins (APPs), C-reactive protein (CRP), serum amyloid-A (SAA) and haptoglobin (Hp), were examined in 12 tail-bitten and 13 control pigs. The median concentrations of APPs were higher (P<0.01) in bitten (CRP 617.5mg/L, range 80.5-969.9; SAA 128.0mg/L, 6.2-774.4; Hp 2.8g/L, 1.6-3.5) than in control pigs (CRP 65.7mg/L, 28.4-180.4; SAA 6.2mg/L, 6.2-21.4; Hp 1.2g/L, 0.9-1.5). There was a tendency for APP concentrations to rise with the histopathological score but the differences were only statistically significant between some of the scores. Five (42%) bitten cases and one (8%) control pig had partial carcass condemnations owing to abscesses (P=0.07). The results show that tail biting induces an inflammatory response in the tail end leading to an acute phase response and formation of carcass abscesses. PMID:19398209

    Background. The platelet parameters and C-reactive protein (CRP) are markers reflecting a systemic inflammatory response. Among those, CRP is one of the major proteins helpful in determination of severity/activity of chronic spontaneous urticaria (CSU). Aim. To determine relationships between platelet activation indices and serum concentration of CRP, the best marker of acute phase response, and their potential clinical use in CSU patients. Methods. Mean platelet volume (MPV), platelet distribution width (PDW), and platelet count as well as serum CRP concentration were measured in CSU patients, showing different degrees of urticarial severity, and in the healthy subjects. Results. No significant differences were found in MPV and PDW between CSU group and the healthy subjects. The platelet count was significantly higher in moderate-severe CSU than that of the controls and mild CSU patients. Serum CRP concentrations were significantly higher in CSU patients as compared with the healthy subjects and significantly correlated with the platelet count in CSU patients. Conclusions. Acute phase response in CSU is associated with the increased number of circulating platelets in patients with more severe symptoms. It seems that simple determination of platelet size indices is not a reliable indicator of CSU severity/activity. PMID:25025065

    Protein electrophoresis has recognized applications in determining the health status of various species. While reference intervals for electrophoresis have been determined for psittacine and raptor species, there are none reported for Phoenicopteriformes species. Reference intervals for haptoglobin and protein fractions obtained by electrophoresis were determined for the American flamingo (Phoenicopterus ruber) based on plasma samples from 39 captive birds. The reference intervals were as follows: haptoglobin, 0.17-0.8 mg/ml; total protein, 3.65-6.38 g/dl; prealbumin, 0.26-1.9 g/dl; albumin, 1.51-3.12 g/dl; α-1 globulin, 0.06-0.38 g/dl; α-2 globulin, 0.17-0.67 g/dl; β globulin, 0.38-1.33 g/dl; γ globulin, 0.26-0.68 g/dl; albumin : globulin ratio, 0.93-2.17. As captive flamingos often suffer from pododermatitis, feet of all flamingos were scored to determine if pododermatitis would be reflected in the acute phase proteins. Spearman rank correlation was performed on each of the protein fractions and pododermatitis scores, and only albumin had a significant correlation. This indicates that albumin, as a negative acute phase protein, may be a marker for this disease process.

    PubMed

    2016-03-15

    Pentraxin-3 (PTX3) is an acute phase protein (APP) and a member of the long pentraxin family that is recognised for its role in peripheral immunity and vascular inflammation in response to injury, infection and diseases such as atherosclerosis, cancer and respiratory disease. Systemic levels of PTX3 are highly elevated in these conditions, and PTX3 is now recognised as a new biomarker of disease risk and progression. There is extensive evidence demonstrating that central nervous system (CNS) disorders are primarily characterised by central activation of innate immunity, as well as activation of a potent peripheral acute phase response (APR) that influences central inflammation and contributes to poor outcome. PTX3 has been recently recognised to play important roles in CNS disorders, having both detrimental and neuroprotective effects. The present review aims to give an up-to-date account of the emerging roles of PTX3 in CNS disorders, and to provide a critical comparison between peripheral and central actions of PTX3 in inflammatory diseases.

    Infection and undernutrition are prevalent in developing countries and demonstrate a synergistic relation. Undernutrition increases infection-related morbidity and mortality. The acute phase response (APR) is an innate, systemic inflammatory reaction to a wide array of disruptions in a host’s homeostasis, including infection. Released from immune cells in response to deleterious stimuli, proinflammatory cytokines act on distant tissues to induce behavioral (e.g., anorexia, weakness, and fatigue) and systemic effects of the APR. Cytokines act to increase energy and protein requirements to manifest fever and support hepatic acute phase protein (APP) production. Blood concentrations of glucose and lipid are augmented to provide energy to immune cells in response to cytokines. Additionally, infection decreases intestinal absorption of nutrients and can cause direct loss of micronutrients. Traditional indicators of iron, zinc, and vitamin A status are altered during the APR, leading to inaccurate estimations of deficiency in populations with a high or unknown prevalence of infection. Blood concentrations of APPs can be measured in nutrition interventions to assess the time stage and severity of infection and correct for the APR; however, standardized cutoffs for nutrition applications are needed. Protein-energy malnutrition leads to increased gut permeability to pathogens, abnormal immune cell populations, and impaired APP response. Micronutrient deficiencies cause specific immune impairments that affect both innate and adaptive responses. This review describes the antagonistic interaction between the APR and nutritional status and emphasizes the need for integrated interventions to address undernutrition and to reduce disease burden in developing countries.

    The relative efficacy and safety of dabigatran etexilate and warfarin have been evaluated in two head-to-head, phase III, treatment of acute venous thromboembolism (VTE) trials, and one extended prophylaxis trial, in patients with high risk of recurrent VTE. Dabigatran etexilate demonstrated similar efficacy to warfarin, and was associated with a reduced risk of major or clinically relevant bleeds. Based on results of these trials, and real-life disease prognosis following discontinuation of anticoagulation treatment, we evaluated the cost-utility of dabigatran etexilate compared with warfarin in six months anticoagulation, and in extended, up to 24 months anticoagulation, in patients with acute VTE, acute deep-vein thrombosis (DVT) or acute, symptomatic, pulmonary embolism (PE). Costs were analysed from the perspective of the National Health Services (NHS) and Public Social Services (PSS) in England and Wales. Outcomes were quantified in quality-adjusted life years (QALY). The estimated incremental, lifetime cost/QALY gain following acute, symptomatic VTE (DVT or PE) was £1,252/QALY when dabigatran etexilate or warfarin were administered for up to six months treatment. In treatment of acute, symptomatic PE and in DVT respective ratios were £1,767/QALY and £1,075/QALY. In extended, up to 24 months anticoagulation, dabigatran etexilate projected costs/QALY of £8,242/QALY, when compared with warfarin. Results obtained herein were robust across a number of sensitivity analyses and suggest dabigatran etexilate to be a cost-effective alternative to current standard of care when evaluated in six months treatment and in extended anticoagulation following acute VTE (DVT and/or PE).

    Posttraumatic osteoarthritis is caused by a cascade of pathobiologic and pathomechanical events starting with intraarticular fractures in the cartilage. Currently, treatment of fractures is completely focused on restoration of the macroanatomy of the joint. The premise is that restoring the macroanatomy will prevent ongoing stresses and in turn prevent cartilage degeneration. However, current treatment ignores acute mechanical damage sustained by cartilage at the time of injury. This study describes the initial development of a novel nanocomposite photopolymerizing copolymer that has potential to restore local structural integrity to acutely injured cartilage, and subsequently act as a carrier for chondrocyte-enhancing bioactive agents.

    1993-12-01

    Potentially harmful stimulation of the neuroendocrine axis occurs in the early hours of myocardial infarction. It has been suggested that this acute neuroendocrine response might be attenuated by early therapeutic reperfusion. To test this hypothesis we measured plasma concentrations of atrial natriuretic factor (ANF), renin, adrenaline (ADR) and noradrenaline (NADR) on admission and at 1 h and 4 h in 32 patients undergoing streptokinase treatment within 6 h of myocardial infarction. Fractional changes (FC) in hormone levels were calculated: e.g. ANFO-ANF4/ANFO. Resolution of ST segment elevation at 4 h was the primary measure of reperfusion. Sixteen patients showed ST segment resolution. There was no difference in hormone levels at baseline between reperfused and non-reperfused patients. Fractional changes in ANF, renin and ADR were similar in both groups. NADR fell from admission to 4 h in reperfused patients but rose in non-reperfused (FC 0.28 vs -0.10; P = 0.054). There was no difference in the changes in pulse rate or blood pressure from admission to 4 h between the two groups. Thus there is no evidence that early reperfusion acutely alters the release of ANF, renin or ADR to myocardial infarction. Although plasma NADR tended to fall acutely in reperfused patients this was not accompanied by other markers of sympathetic withdrawal.

    Acute otitis media (AOM) is the most common bacterial infection in children and has a very varied clinical spectrum, ranging from spontaneous resolutions to serious complications. The effect of antibiotics in AOM depends on the chosen outcome, but has been shown to reduce pain somewhat, and have a greater beneficial effect in severe cases of AOM. Today, not all episodes of AOM are treated with antibiotics, but most countries have issued guidelines that include an option of watchful waiting in many cases. Prevention of AOM reaches from modification of environmental risk factors to vaccinations and surgery. Conjugate pneumococcal vaccines and influenza vaccines have been shown to somewhat reduce the number of AOM episodes in different groups of children. Grommets, with or without adenoidectomy, are effective at least during the first 6 months after surgery. PMID:25896748

    Adenosine receptors have been the target of intense research with respect to potential use of selective ligands in a variety of therapeutic areas. Caffeine and theophylline are adenosine receptor antagonists, and over the past three decades a wide range of selective agonists and antagonists for adenosine receptor subtypes have been developed. A complication to the therapeutic use of adenosine receptor ligands is the observation that the effects of acute administration of a particular ligand can be diametrically opposite to the chronic effects of the same ligand. This ‘effect inversion’ is discussed here by Ken Jecobson and colleagues, and has been observed for effects on cognitive processes, seizures and ischaemic damage. PMID:8936347

  11. How to Assess Drugs in the Treatment of Acute Bipolar Mania?

    PubMed Central

    Bourin, Michel; Thibaut, Florence

    2012-01-01

    Bipolar affective disorder is a serious mental disease associated with significant morbidity and mortality. Good-quality research available to guide treatment strategies remains insufficient, particularly with regard to manic or hypomanic episodes. A critical review of the various stages of mania might be helpful for pharmaceutical companies and investigators as a prerequisite for the clinical evaluation of potential antimanic properties of medications. The main difficulty is with a comparison between anticonvulsants, antipsychotics, and mood stabilizers such as lithium (with equal efficacy in the acute phase and the prevention of recurrent manic episodes). No consensus has been reached with regard to the treatment of bouts of acute mania in various parts of the world. Controlled clinical trials have, at last, provided irrefutable evidence of the activity of lithium, which has long been used alone, as well as that of divalproate or its derivatives and, to a lesser extent, carbamazepine. The new antipsychotic agents have more recently established their efficacy, especially aripiprazole, asenapine, quetiapine; olanzapine, risperidone, and ziprasidone (not sure where the paradox is). In Europe, haloperidol is still the reference substance used in clinical trials despite the fact that it is not officially indicated in the treatment of mania. In the USA, lithium, divalproate, or antipsychotics can be prescribed as first-line treatment. In Europe, lithium remains the first-line medication, whereas divalproate and atypical antipsychotic agents are used only as second-line therapy. Although both types of medication (antipsychotics, normothymic agents, and/or anticonvulsants) have proved to be clinically effective in the management of mania by reducing the mania scores overall, the same does not apply, however, to all symptoms of mania. Factorial approaches to mania have all shown that since there are several clinical forms of mania, several clusters of manic symptoms can

    Use of all-transretinoic acid (ATRA) with other chemotherapeutic agents in the treatment of acute promyelocytic leukemia (APL) has been shown to cause the differentiation of abnormally granulated specific blast cells into mature granulocytes by acting on the t(15; 17) fusion gene product. The complete remission rate is increased and survival time is prolonged in APL patients who receive chemotherapy plus ATRA, whereas ATRA syndrome and other ATRA-related adverse effects including pseudo tumor cerebri, headache, severe bone pain, mucosal and skin dryness, hypercholesterolemia, and cheilitis may be observed especially during induction phase of the treatment. In this paper, we report a 9-year-old girl with APL who developed pancarditis while receiving the APL-93 treatment protocol. In our patient, endocarditis and myocarditis were initially determined after ATRA treatment during the induction part of the protocol. All findings disappeared after ATRA was discontinued. When ATRA was readministered in the maintenance part of the treatment protocol, she developed pancarditis and severe pulmonary edema. As her symptoms decreased dramatically with the discontinuation of ATRA and the initiation of steroid treatment, the clinical picture strongly suggested the ATRA treatment as the causative factor. To the best of our knowledge, this clinical picture of pancarditis secondary to ATRA treatment has not been reported earlier in the English literature. PMID:20881874

    2015-10-01

    Blinatumomab is a CD19/CD3 bispescific antibody designed to redirect T cells toward malignant B cells and induce their lysis. It recently gained accelerated approval by the FDA for the treatment of relapsed or refractory Philadelphia chromosome-negative B-cell acute lymphoblastic leukemia (RR-ALL). In the phase II trial that served as the basis for approval, blinatumomab demonstrated significant single-agent activity and induced remission [complete remission (CR) and CR with incomplete recovery of peripheral blood counts (CRh)] in 43% of 189 adult patients with RR-ALL; the majority of responders (82%) also attained negative minimal residual disease (MRD(-)) status that did not generally translate into long-term remissions in most cases. Additional studies show that blinatumomab can induce high response rates associated with lasting remissions in patients in first remission treated for MRD positivity, suggesting a role for blinatumomab in the upfront, MRD-positive setting. Blinatumomab infusion follows a predictable immunopharmacologic profile, including early cytokine release that can be associated with a clinical syndrome, T-cell expansion, and B-cell depletion. Neurologic toxicities represent a unique toxicity that shares similarities with adverse effects of other T-cell engaging therapies. Further studies are needed to clarify the optimal disease setting and timing for blinatumomab therapy. Additional insights into the pathogenesis, risk factors, and prevention of neurologic toxicities as well as a better understanding of the clinical consequences and biologic pathways that are associated with drug resistance are needed.

    Objective To assess the safety and efficacy of etoricoxib, a selective cyclo-oxygenase-2 inhibitor, in comparison with indometacin in the treatment of acute gouty arthritis. Design Randomised, double blind, active comparator controlled trial. Setting 43 outpatient study centres in 11 countries. Participants 142 men and eight women (75 patients per treatment group) aged 18 years or over presenting with clinically diagnosed acute gout within 48 hours of onset. Interventions Etoricoxib 120 mg administered orally once daily versus indometacin 50 mg administered orally three times daily, both for 8 days Main outcome measures Patients' assessment of pain in the study joint over days 2 to 5 (primary end point); investigators' and patients' global assessments of response to treatment and tenderness of the study joint (key secondary end points). Results Etoricoxib showed efficacy comparable to indometacin. Patients' assessment of pain in the study joint (0-4 point Likert scale, “no pain” to “extreme pain”) over days 2 to 5 showed a least squares mean change from baseline of −1.72 (95% confidence interval −1.90 to −1.55) for etoricoxib and −1.83 (−2.01 to −1.65) for indometacin. The difference between treatment groups met prespecified comparability criteria. All other efficacy end points, including those reflecting reduction in inflammation and analgesia, provided corroborative evidence of comparable efficacy. Significant pain relief was evident at the first measurement, 4 hours after the first dose of treatment. Prespecified safety analyses revealed that drug related adverse experiences occurred significantly less frequently with etoricoxib (22.7%) than with indometacin (46.7%) (P=0.003), although overall adverse experience rates were similar between the two treatment groups. Conclusion Etoricoxib 120 mg once daily provides rapid and effective treatment for acute gouty arthritis comparable to indometacin 50 mg three times daily. Etoricoxib was generally

Here, we assumed that major ozonated autohemotherapy contributes to recovery of clinical function, possibly by reducing remote injury after acute cerebral infarction. Sixty acute cerebral infarction patients aged 30-80 years were equally and randomly allocated to ozone treatment and control groups. Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy (47 mg/L, 100 mL ozone) for 10 ± 2 days. Patients in the control group received medical treatment only. National Institutes of Health Stroke Scale score, modified Rankin scale score, and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased, brain function improved, clinical efficiency significantly increased, and no obvious adverse reactions detected in the ozone treatment group compared with the control group. These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury, and additionally, exhibits high safety.

  17. Early treatment of acute migraine: new evidence of benefits.

    PubMed

    Valade, D

    2009-12-01

    The current management approach to migraine headaches advocates use of triptan medications early in the course of an attack while pain is still mild, rather than waiting to treat the pain when it has progressed to moderate-severe. Recently, strong new evidence for the benefits of early intervention has become available. The AEGIS, AIMS and AwM studies of almotriptan in patients with migraine indicate that earlier treatment initiation and lower pain intensity at the time of treatment are important predictors of enhanced therapeutic outcomes. The opportunity to treat early exists for about 50% of all migraine attacks, which offers considerable scope for improving migraine management. Importantly, treating pain early and before it has progressed beyond 'mild' meets many of the expectations patients have of their migraine treatment. It is believed that consistent, positive outcomes may assist in overcoming the various physician- and patient-perceived barriers to adoption of this beneficial treatment strategy. PMID:20017750

  18. Treatment of incest perpetrators: a five-phase model.

    PubMed

    Frenken, J

    1994-04-01

    The author's experiences with treating fathers who committed incest and were sentenced to undergo therapy are discussed in this paper. The treatment consists of five phases. Following crisis intervention and assessment, an analysis is made of the sequence of events, thoughts, moods, and behaviors that precede sexual contact. In the third phase, the client's sense of guilt is brought out and he actively takes responsibility for the sexual abuse of his daughter. In the fourth phase, the origin of the sexual abuse is clarified as it is put into the context of his own problems and the problems within the family. In the fifth phase, strategies for relapse prevention are practiced. In addition there are partner-relationship sessions with the couple as well as family counseling sessions. Up to now none of the clients have recidivized.

    The outcome of patients with acute promyelocytic leukaemia (APL) has dramatically improved over the last two decades, due to the introduction of combined all-trans retinoic acid (ATRA) and chemotherapy regimens and, more recently, to the advent of arsenic trioxide (ATO). ATRA and anthracycline-based chemotherapy remains a widely used strategy, providing cure rates above 80%, but it is associated with risk of severe infections and occurrence of secondary leukaemias. ATO is the most effective single agent in APL and, used alone or in combination with ATRA or ATRA and reduced-intensity chemotherapy, results in greater efficacy with considerably less haematological toxicity. The toxic profile of ATO includes frequent, but manageable, QTc prolongation and increase of liver enzymes. Two large randomized studies have shown that ATRA + ATO is superior to ATRA + chemotherapy for newly diagnosed low-risk APL resulting in 2-4 year event-free survival rates above 90% and very few relapses. According to real world data, the spectacular progress in APL outcomes reported in clinical trials has not been paralleled by a significant improvement in early death rates, this remains the most challenging issue for the final cure of the disease.

    Patients with acute myeloid leukaemia (AML) or myelodysplastic syndrome (MDS) may respond to treatment with epigenetic-modifying agents. Histone deacetylase inhibitors may synergize with hypomethylating agents. This phase 1 dose-escalation study was designed to determine the maximum tolerated dose, recommended phase 2 dose, safety and tolerability of vorinostat plus decitabine in patients with relapsed/refractory AML, newly-diagnosed AML, or intermediate- to high-grade MDS. Thirty-four patients received concurrent therapy with decitabine plus vorinostat and 37 received sequential therapy with decitabine followed by vorinostat. Twenty-nine patients had relapsed/refractory AML, 31 had untreated AML and 11 had MDS. The target maximum administered dose (MAD) of decitabine 20 mg/m(2) daily for 5 d plus vorinostat 400 mg/d for 14 d was achieved for concurrent and sequential schedules, with one dose-limiting toxicity (Grade 3 QTc prolongation) reported in the sequential arm. Common toxicities were haematological and gastrointestinal. Responses were observed more frequently at the MAD on the concurrent schedule compared with the sequential schedule in untreated AML (46% vs. 14%), relapsed/refractory AML (15% vs. 0%) and MDS (60% vs. 0%). Decitabine plus vorinostat given concurrently or sequentially appears to be safe and well-tolerated. Concurrent therapy shows promising clinical activity in AML or MDS, warranting further investigation.

    Acute iron intoxication is one of the leading causes of overdose morbidity and mortality in children. The toxicity of iron has been postulated to be related to free radical formation and subsequent lipid peroxidation. Hyperbaric oxygen treatment can result in a number of beneficial biochemical, cellular and physiological effects, and has recently been shown to induce cellular protection against ischaemia, and in some cases against free radical formation. In the current study, we aimed to investigate the effects of hyperbaric oxygen treatment on mortality in acute iron intoxication in rats. After iron administration, 57 animals were divided into two groups: a treatment group receiving hyperbaric oxygen treatment (n = 30) and a control group (n = 27), and followed for 48 hr for signs of severe intoxication. In the second part of the study, 21 animals were divided into a treatment group receiving hyperbaric oxygen treatment (n = 10) and a control group (n = 11), and markers of oxidative stress were evaluated. We showed a significant reduction in mortality in hyperbaric oxygen-treated animals from 17 of 27 (62.9%) among untreated rats to 6 of 30 (20%). Surprisingly, in the treatment group, levels of oxidative stress markers were higher. We postulate that hyperbaric oxygen has a potentially beneficial effect in acute iron intoxication.

    AIM: To study the effect of a new anti-CD163-dexamethasone conjugate targeting activated macrophages on the hepatic acute phase response in rats. METHODS: Wistar rats were injected intravenous with either the CD163 targeted dexamethasone-conjugate (0.02 mg/kg) or free dexamethasone (0.02 or 1 mg/kg) 24 h prior to lipopolysaccharide (LPS) (2.5 mg/kg intraperitoneal). We measured plasma concentrations of tumour necrosis factor-α (TNF-α) and interleukin 6 (IL-6) 2 h post-LPS and liver mRNAs and serum concentrations of the rat acute phase protein α-2-macroglobulin (α-2-M) 24 h after LPS. Also, plasma concentrations of alanine aminotransferase and bilirubin were measured at termination of the study. Spleen weight served as an indicator of systemic steroid effects. RESULTS: The conjugate halved the α-2-M liver mRNA (3.3 ± 0.6 vs 6.8 ± 1.1, P < 0.01) and serum protein (201 ± 48 μg/mL vs 389 ± 67 μg/mL, P = 0.04) after LPS compared to low dose dexamethasone treated animals, while none of the free dexamethasone doses had an effect on liver mRNA or serum levels of α-2-M. Also, the conjugate reduced TNF-α (7208 ± 1977 pg/mL vs 21583 ± 7117 pg/mL, P = 0.03) and IL-6 (15685 ± 3779 pg/mL vs 25715 ± 4036 pg/mL, P = 0.03) compared to the low dose dexamethasone. The high dose dexamethasone dose decreased the spleen weight (421 ± 11 mg vs 465 ± 12 mg, P < 0.05) compared to controls, an effect not seen in any other group. CONCLUSION: Low-dose anti-CD163-dexamethasone conjugate effectively decreased the hepatic acute phase response to LPS. This indicates an anti-inflammatory potential of the conjugate in vivo.

    Mastitis is a benign infection of the breast if it is treated early. If two days elapse before treatment is started, it can lead to serious complications such as chronic or recurrent mastitis or breast abscess. Treatment consists in frequent nursing and massaging or stripping the breast to keep it empty of milk or pus, and appropriate antibiotics. Incision and drainage of a breast abscess can be done in the office under local anesthesia, and the drainage continued at home by the mother. PMID:21253250

  7. Sequential designs for phase III clinical trials incorporating treatment selection.

    PubMed

    2003-03-15

    Most statistical methodology for phase III clinical trials focuses on the comparison of a single experimental treatment with a control. An increasing desire to reduce the time before regulatory approval of a new drug is sought has led to development of two-stage or sequential designs for trials that combine the definitive analysis associated with phase III with the treatment selection element of a phase II study. In this paper we consider a trial in which the most promising of a number of experimental treatments is selected at the first interim analysis. This considerably reduces the computational load associated with the construction of stopping boundaries compared to the approach proposed by Follman, Proschan and Geller (Biometrics 1994; 50: 325-336). The computational requirement does not exceed that for the sequential comparison of a single experimental treatment with a control. Existing methods are extended in two ways. First, the use of the efficient score as a test statistic makes the analysis of binary, normal or failure-time data, as well as adjustment for covariates or stratification straightforward. Second, the question of trial power is also considered, enabling the determination of sample size required to give specified power.

    Neuroleptic malignant syndrome is a rare but potentially lethal, rare reaction to neuroleptics which is characterized by altered levels of consciousness, extrapyramidal effects, autonomic instability, hyperthermia, and elevated serum creatine phosphokinase levels. The most serious complication of neuroleptic malignant syndrome is acute renal failure. We investigated six cases of neuroleptic malignant syndrome associated with myoglobulinemic acute renal failure due to rhabdomyolysis and effect of hemodialysis or hemodiafiltration. The patients were five males and one female with a mean age of 43.5 yr. All of the patients, who developed acute renal failure induced from rhabdomyolysis, had previously received butyrophenone (haloperidol), phenothiazine, benzamide, iminomide, benzisoxazole, antidepressants, and hypnotics (benzodiazepine and barbiturate) for the treatment of schizophrenia. The clinical manifestations of neuroleptic malignant syndrome were characterized by altered consciousness, muscle rigidity and weakness, fever, and excessive perspiration. The peak laboratory data were blood urea nitrogen 102 +/- 26 (mean +/- SD) mg/dL, serum creatinine 9.1 +/- 2.1 mg/dL, serum creatine phosphokinase 229,720 +/- 289,940 IU/L, and all of them developed oliguric acute renal failure. Dantrolene sodium administration was given to five cases and hemodialysis or hemodiafiltration was performed in all of them. The serum creatinine level after hemodialysis or hemodiafiltration was 1.4 +/- 1.0 mg/dL. All patients were successfully cured of acute renal failure by hemodialysis or hemodiafiltration. As a result, myoglobulinemic acute renal failure associated with neuroleptic malignant syndrome was successfully treated by hemodialysis or hemodiafiltration.

    Sixty-eight patients who presented to the casualty ward with acute ankle joint injuries were studied to examine the effect of ibuprofen on pain and ankle swelling. Thirty-two patients were treated with placebo tablets and 36 with 600 mg ibuprofen tablets taken four times a day for 4 to 6 days. All of the patients were immobilized and requested to keep the foot elevated. The results showed that ibuprofen had no effect on the ankle swelling. The need for additional analgesics was not influenced by treatment with ibuprofen, which means that ibuprofen has no effect on pain. The time elapsed from occurrence of the injury to arrival at the casualty ward was negatively correlated to the reduction of ankle joint swelling during the treatment period. Treatment with ice-sprays, icebags, or cold water during the acute stage of injury did not influence the reduction of swelling during the treatment period. PMID:2675651

    2011-01-01

    Acute promyelocytic leukemia (APL) is a distinct subtype of myeloid leukemia characterized by t(15;17) chromosomal translocation, which involves the retinoic acid receptor-alpha (RAR-alpha). APL typically presents with a life-threatening hemorrhagic diathesis. Before the introduction of all-trans retinoic acid (ATRA) for the cure of APL, fatal hemorrhages due, at least in part, to the APL-associated coagulopathy, were a major cause of induction remission failure. The laboratory abnormalities of blood coagulation found in these patients indicate the occurrence of a hypercoagulable state. Major determinants of the coagulopathy of APL are endogenous factors expressed by the leukemic cells, including procoagulant factors, fibrinolytic proteins, and non-specific proteolytic enzymes. In addition, these cells have an increased capacity to adhere to the vascular endothelium, and to secrete inflammatory cytokines [i.e. interleukin-1beta (IL-1beta) and tumor necrosis factor (TNF-alpha)], which in turn stimulate the expression of prothrombotic activities by endothelial cells and leukocytes. ATRA can interfere with each of the principal hemostatic properties of the leukemic cell, thus reducing the APL cell procoagulant potential, in parallel to the induction of cellular differentiation. This effect occurs in vivo, in the bone marrow of APL patients receiving ATRA, and is associated with the improvement of the bleeding symptoms. Therapy with arsenic trioxide (ATO) also beneficially affects coagulation in APL. However, early deaths from bleeding still remain a major problem in APL and further research is required in this field. In this review, we will summarize our current knowledge of the pathogenesis of the APL-associated coagulopathy and will overview the therapeutic approaches for the management of this complication.

    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.

    When delivered within 1 and in most cases 2 hours of permanent middle cerebral artery occlusion (pMCAO), mild sensory stimulation (intermittent single whisker stimulation) was shown to be completely neuroprotective according to assessment with multiple techniques 24 hours after pMCAO in a rodent model of ischemic stroke (Lay et al., 2010). The acute effect of stimulation treatment on the ischemic cortex however, had yet to be reported. Here we characterize cortical function and perfusion during the 120 minute whisker stimulation period in four experimental groups with treatment initiated 0, 1, 2 hours (protected groups) or 3 hours post-pMCAO (unprotected group) using multiple techniques. According to functional imaging, a gradual return of evoked whisker functional representation to baseline levels was initiated with treatment onset and completed within the treatment period. Evoked neuronal activity and reperfusion to the ischemic area also showed a gradual recovery in protected animals. Surprisingly, a similar recovery profile was observed in response to treatment in all protected animals, irrespective of treatment onset time. Non-stimulated pMCAO control group data demonstrate that reperfusion is not spontaneous. This makes the complete protection observed in the majority of animals stimulated at 2 hours post-pMCAO even more surprising as these animals recovered despite having been in this severely ischemic state for two full hours. In summary, when delivered within a 2 hour window post- pMCAO, whisker stimulation treatment initiated reperfusion and a gradual recovery of cortical function that was completed or nearly completed within the treatment period.

    Background Health care service based on telemedicine can reduce both physical and time barriers in stroke treatments. Moreover, this service connects centers specializing in stroke treatment with other centers and practitioners, thereby increasing accessibility to neurological specialist care and fibrinolytic treatment. Objective Development, implementation, and evaluation of a care service for the treatment of acute stroke patients based on telemedicine (TeleStroke) at Virgen del Rocío University Hospital. Methods The evaluation phase, conducted from October 2008 to January 2011, involved patients who presented acute stroke symptoms confirmed by the emergency physician; they were examined using TeleStroke in two hospitals, at a distance of 16 and 110 kilometers from Virgen del Rocío University Hospital. We analyzed the number of interconsultation sheets, the percentage of patients treated with fibrinolysis, and the number of times they were treated. To evaluate medical professionals’ acceptance of the TeleStroke system, we developed a web-based questionnaire using a Technology Acceptance Model. Results A total of 28 patients were evaluated through the interconsultation sheet. Out of 28 patients, 19 (68%) received fibrinolytic treatment. The most common reasons for not treating with fibrinolysis included: clinical criteria in six out of nine patients (66%) and beyond the time window in three out of nine patients (33%). The mean “onset-to-hospital” time was 69 minutes, the mean time from admission to CT image was 33 minutes, the mean “door-to-needle” time was 82 minutes, and the mean “onset-to-needle” time was 150 minutes. Out of 61 medical professionals, 34 (56%) completed a questionnaire to evaluate the acceptability of the TeleStroke system. The mean values for each item were over 6.50, indicating that respondents positively evaluated each item. This survey was assessed using the Cronbach alpha test to determine the reliability of the

    Vascular disorders have a direct link to mortality in the acute phase of Trypanosoma cruzi infection. However, the underlying mechanisms of vascular dysfunction in this phase are largely unknown. We hypothesize that T. cruzi invades endothelial cells causing dysfunction in contractility and relaxation of the mouse aorta. Immunodetection of T. cruzi antigen TcRBP28 was observed in endothelial cells. There was a decreased endothelial nitric oxide synthase (eNOS)-derived NO-dependent vascular relaxation, and increased vascular contractility accompanied by augmented superoxide anions production. Endothelial removal, inhibition of cyclooxygenase 2 (COX-2), blockade of thromboxane A2 (TXA2) TP receptors, and scavenger of superoxide normalized the contractile response. COX-2, thromboxane synthase, inducible nitric oxide synthase (iNOS), p65 NFκB subunit and p22(phox) of NAD(P)H oxidase (NOX) subunit expressions were increased in vessels of chagasic animals. Serum TNF-α was augmented. Basal NO production, and nitrotyrosine residue expression were increased. It is concluded that T. cruzi invades mice aorta endothelial cells and increases TXA2/TP receptor/NOX-derived superoxide formation. Alongside, T. cruzi promotes systemic TNF-α increase, which stimulates iNOS expression in vessels and nitrosative stress. In light of the heart failure that develops in the chronic phase of the disease, to understand the mechanism involved in the increased contractility of the aorta is crucial.

    Traumatic brain injury (TBI) has been known to be the leading cause of breakdown and long-term disability in people under 45 years of age. This study highlights the effective factors on post-traumatic (PT) linguistic disorder and relations between linguistic and cognitive function after trauma in adults with acute TBI. A cross-sectional design was employed to study 60 post-TBI hospitalized adults aged 18-65 years. Post-traumatic (PT) linguistic disorder and cognitive deficit after TBI were respectively diagnosed using the Persian Aphasia Test (PAT) and Persian version of Mini-Mental State Examination (MMSE) at discharge. Primary post-resuscitation consciousness level was determined using the Glasgow Coma Scale (GCS). Paracilinical data was obtained by CT scan technique. Multiple logistic regression analysis illustrated that brain injury severity was the first powerful significant predictor of PT linguistic disorder after TBI and frontotemporal lesion was the second. It was also revealed that cognitive function score was significantly correlated with score of each language skill except repetition. Subsequences of TBI are more commonly language dysfunctions that demand cognitive flexibility. Moderate, severe and fronto-temporal lesion can increase the risk of processing deficit in linguistic macrostructure production and comprehension. The dissociation risk of cortical and subcortical pathways related to cognitive-linguistic processing due to intracranial lesions can augment possibility of lexical-semantic processing deficit in acute phase which probably contributes to later cognitive-communication disorder.

  19. Molecular and cellular mechanisms used in the acute phase of stimulated steroidogenesis.

    Steroidogenic tissue can respond almost immediately to a stimulatory hormonal stimuli. Recent findings are shedding light on the molecular and cellular mechanisms that are used to synthesize and export steroid hormones in the acute phase of stimulation. In addition to utilising the cAMP intracellular messenger system to convey a stimulatory message, steroidogenic cells may employ the protein kinase C, arachidonic acid, tyrosine phosphate and nitrous oxide systems. It has been proposed that cholesterol laden vesicles travel along a network of intermediate filaments to reach the mitochondria. Cholesterol may then translocate from the outer mitochondrial membrane to the inner via sites of contact between the two membranes. These contact sites may be composed of protein bridges which include the constituents, porin, the benzodiazepine receptor and GTP binding proteins. Cholesterol is transported through the contact sites to the inner membrane and on reaching cytochrome P450 side chain cleavage (P450scc), cholesterol is converted to pregnenolone. Pregnenolone is in turn converted to a range of steroid hormones via enzyme casades. GTP binding proteins may regulate the contact site between the inner and outer membranes and thereby modulate cholesterol flux to P450scc. In the adrenal and gonads the rate that cholesterol traverses the contact point to reach the inner membrane is accelerated by the steroidogenic acute regulatory protein. Newly synthesized steroid hormones are transported to the cell periphery for export via a mechanism that may utilise an ion exchange protein.

    Sunitinib is a multiple tyrosine kinase receptors inhibitor that is approved for the treatment of advanced renal cell carcinoma. Amongst its targets are fetal liver tyrosine kinase receptor 3 (FLT 3) and vascular endothelial growth factor receptor (VEGFR). Renal toxicity has not been reported from the trials, but several patients have been reported to develop a pre-eclampsia-like syndrome. We report the first case of acute tubular necrosis in a patient with multiple myeloma following treatment with sunitinib.

    Molecular hydrogen (H2 ) has been proven to be an effective agent that can cure multiple organ diseases by reducing oxidative stress. Although the protective effect of hydrogen on acute pancreatitis (AP) has been confirmed, its molecular mechanism is still unclear. In this article, we aimed to investigate the changes in pancreatic cell protein expression associated with the protective effect of H2 against AP and attempted to uncover the molecular mechanism underlying this process. A proteomic analysis identified 73 differentially expressed proteins and generated the protein-protein interaction networks of these proteins. The results triggered our interest in mitogen-activated protein kinase (MAPK) and heat shock cognate 71 kDa protein (Hsc70). The subsequent in vitro experiments showed that H2 treatment inhibited the phosphorylation of extracellular signal-regulated kinase (ERK), c-jun N-terminal kinase (JNK), and p38 MAPK, and activated NF-κB and the expression of tumor necrosis factor α and interleukin-1β, while simultaneously preventing the translocation of phospho-ERK, phospho-JNK, and phospho-p38 from the cytoplasm to the nucleus. Furthermore, Hsc70 expression was upregulated by H2 administration. The animal experimental results were consistent with those of the in vitro experiments. In conclusion, H2 treatment can ameliorate the inflammatory response and reduce the expression of inflammatory mediators during the early phase of AP by inhibiting the MAPK pathways and increasing Hsc70 expression.

    The present study was designed to assess the anti-inflammatory activity of hyperbaric oxygen treatment by comparing it with that of diclofenac, a nonsteroidal anti-inflammatory drug, and also to investigate whether hyperbaric oxygen treatment enhances the anti-inflammatory effect of diclofenac in carrageenan-induced paw edema which is commonly employed as an acute inflammation model in rats. Hyperbaric oxygen treatment and diclofenac (20 mg/kg) markedly reduced the carrageenan-induced paw edema in rats. In other words, they displayed anti-inflammatory activity. On the other hand, hyperbaric oxygen treatment did not consistently modify the anti-inflammatory effect of diclofenac in this model.

    While the majority of children and adolescents with newly diagnosed childhood acute lymphoblastic leukemia (ALL) will be cured, as many as 20 % of patients will experience relapse. On current treatment regimens, the intensity of upfront treatment is stratified based upon prognostic factors with the aim of improving cure rates (for those at the highest risk of relapse) and minimizing treatment-related morbidity (for lower-risk patients). Here we review advances in the understanding of prognostic factors and their application. We also highlight novel treatment approaches aimed at improving outcomes in childhood ALL.

    After a severe burn, the liver plays a pivotal role by modulating inflammatory processes, metabolic pathways, immune functions, and the acute phase response. Therefore, liver integrity and function are important for recovery. A thermal injury, however, causes hepatic damage by inducing hepatic edema, fatty infiltration, hepatocyte apoptosis, and metabolic derangements associated with insulin resistance and impaired insulin signaling. In preliminary studies, we found that these pathophysiological processes are related to hepatic inflammation, altered intracellular signaling, and mitochondrial dysfunction. We hypothesize that modulation of these processes with insulin could improve hepatic structure and function and, therefore, outcome of burned and critically ill patients. Insulin administration improves survival and decreases the rate of infections in severely burned and critically ill patients. Here, we show that insulin administration decreases the synthesis of proinflammatory cytokines and signal transcription factors and improves hepatic structure and function after a severe burn injury; insulin also restores hepatic homeostasis and improves hepatic dysfunction postburn via alterations in the signaling cascade.

    Estimation of the concentration of C9, C-reactive protein (CRP) and alpha1-antitrypsin in forty sera from patients with Behcet's syndrome and recurrent oral ulcers showed significantly increased amounts of C9 and CRP in Behcet's syndrome. The concentration of C9 was also significantly raised in recurrent oral ulceration, though to a lesser extent than in Behcet's syndrome. The assay C9 and CRP might be useful in the differential diagnosis of Behcet's syndrome, especially from recurrent oral ulcers. It is suggested that during epithelial inflammation in recurrent oral ulcers some of the acute phase proteins are increased and in some patients these may modulate the immunological mechanism in such a way as to induce a transition from focal oral ulceration to the multifocal Behcet's syndrome.

    The psychoanalytic understanding of suicide has greatly expanded in the past 30 years, and the older therapeutic approach has been modified. Although the turning of murder on the self inferred by Freud 90 years ago remains a cornerstone, current practice concentrates on the identification of a precipitating event, the escalation of intolerable painful affect that the patient cannot moderate, the self-perception of helplessness, the evolution of hopelessness as a secondary affect, increasing fantasies of suicide as a means of escape, and ego regression (self-deconstruction), leading progressively to suicide. Recent clinical research, advances in the study of cognition, and neurobiological studies have contributed to the reorientation and enrichment of the psychoanalytic perspective on suicide. The treatment of a university student who had fallen into a suicide crisis is discussed from the psychoanalytic point of view, and evidence for the efficacy of this treatment is reviewed.

    Treatment outcomes of pediatric cancers have improved greatly with the development of improved treatment protocols, new drugs, and better supportive measures, resulting in overall survival rates greater than 70%. Survival rates are highest in acute lymphoblastic leukemia, reaching more than 90%, owing to risk-based treatment through multicenter clinical trials and protocols developed to prevent central nervous system relapse and testicular relapse in boys. New drugs including clofarabine and nelarabine are currently being evaluated in clinical trials, and other targeted agents are continuously being developed. Chimeric antigen receptor-modified T cells are now attracting interest for the treatment of recurrent or refractory disease. Stem cell transplantation is still the most effective treatment for pediatric acute myeloid leukemia (AML). However, in order to reduce treatment-related death after stem cell transplantation, there is need for improved treatments. New drugs and targeted agents are also needed for improved outcome of AML. Surgery and radiation therapy have been the mainstay for brain tumor treatment. However, chemotherapy is becoming more important for patients who are not eligible for radiotherapy owing to age. Stem cell transplant as a means of high dose chemotherapy and stem cell rescue is a new treatment modality and is often repeated for improved survival. Drugs such as temozolomide are new chemotherapeutic options. In order to achieve 100% cure in children with pediatric cancer, every possible treatment modality and effort should be considered.

    The aim of the study was to evaluate markers of the acute phase response (APR) in eventing horses by measuring acute phase proteins (APP) (haptoglobin, Hp, and serum amyloid A, SAA), lysozyme, protein adducts such as pentosidine-like adducts (PENT), malondialdehyde adducts (MDA), hydroxynonenal adducts (HNE) and total advanced glycation/glycoxidation end products (AGEs), complete blood count and lymphocyte subpopulations (CD4+, CD8+ and CD21+) both at rest and at the end of an eventing competition. Blood samples were collected from eight Warmblood horses (medium age 10 ± 3) during an official national 2-day event competition at rest (R) and 10 min after the arrival of the cross-country test on the second day. Exercise caused a significant increase in red blood cell number, haemoglobin, packed cell volume, neutrophils, white blood cell and lymphocyte number; however, these values remained within the normal range. The CD4+ and CD8+ cells significantly increased, whereas the CD21+ lymphocytes decreased; a significant increase in serum SAA, lysozyme and protein carbonyl derivates was also observed. Two-day event causes significant changes in APR markers such as lysozyme, protein carbonyl derivates (HNE, AGEs, PENT) and lymphocyte subpopulations. The data support the hypothesis that 2-day event may alter significantly APR markers. Limitations of the study were the relatively small sample size and sampling time conditioned by the official regulations of the event. Therefore, further studies are needed to investigate the time required for recovery to basal values in order to define the possible effects on the immune function of the athlete horse.

    Osteoporosis in adult life is associated with a significant morbidity and may be predisposed to by osteopenia and failure to reach peak bone mass in childhood. Children treated for acute lymphoblastic leukemia (ALL) may be at risk of osteopenia as a result of previous therapy or as a consequence of the disease process itself. Dual energy x-ray absorptiometry measurements of bone mineral content (BMC) for the whole body and at the lumbar spine and hip were taken in 35 (14 male) long-term survivors of ALL and compared with results in 20 (10 male) survivors of other malignancies and 31 (17 male) healthy sibling controls. The measured BMC was expressed as a percentage of a predicted value derived from the control group and based on the variables that had influence upon it. BMC (%) was reduced at the spine in the ALL group compared with controls [92.4 (8.0)% versus 100.4 (9.7)%, respectively; p < 0.005] and at the hip compared with both other malignancies and controls [89.0 (11.5)% versus 96.1 (11.7)% and 100.4 (9.2)%, respectively; p < 0.0005]. Increasing length of time off therapy was associated with a significant increase in %BMC at both the spine and the hip. For the spine, this association was significantly different between the ALL group and other malignancies, suggesting that any gain in %BMC after therapy was slower in children treated for ALL. Both exercise capacity and levels of physical activity were correlated with %BMC at the hip (r = 0.44, p < 0.001 and r = 0.29, p < 0.01, respectively). Previous exposure to methotrexate, ifosfamide, and bleomycin was associated with a reduction in %BMC at the spine. Exposure to 6-mercaptopurine and cisplatin was associated with a reduction at the hip. In conclusion, children treated for ALL are osteopenic. The mechanism is probably multifactorial but is partially related to previous chemotherapy, limited exercise capacity, and relative physical inactivity.

    Patients with sepsis or after major surgery have decreased plasma levels of the anticoagulant protein antithrombin. In such patients elevated levels of interleukin-6 (IL-6) are present and this interleukin is known to induce positive and negative acute phase responses. To investigate the possibility that antithrombin acts as a negative acute phase response-protein we performed studies on the human hepatoma cell line HepG2 in vitro and baboons in vivo. HepG2 cells were treated with recombinant human IL-6, IL-1beta, or combinations of the latter two, and tested for production of antithrombin, fibrinogen and prealbumin (transthyretin). This treatment resulted in a dose dependent increase in fibrinogen concentration (with a maximum effect of 2.8-2.9-fold) and a dose dependent decrease in prealbumin (with a maximum effect of 0.6-0.7-fold) and antithrombin concentrations (with a maximum effect of 0.6-0.8-fold). Simultaneous treatment of the HepG2 cells with IL-6 (1,000 pg/ml or 2,500 pg/ml) and IL-1beta (25 pg/ml), provided more extensively decreased prealbumin (0.8 and 0.6-fold, respectively) and antithrombin concentration (0.7 and 0.6-fold, respectively) compared to the single interleukin treatment at these concentrations. Baboons treated with 2 microg IL-6 x kg body-weight(-1) x day(-1) showed increased plasma CRP levels (59-fold, p <0.05) and decreased prealbumin (0.9-fold, p <0.05) and antithrombin (0.8-fold, p <0.05) plasma levels, without evidence for coagulation activation. Our results indicate that antithrombin acts as a negative acute phase protein, which may contribute to the decreased antithrombin plasma levels observed after major surgery or in sepsis.

    A two-year-old girl had had fever for one week, and since the previous day general malaise, cutaneous pustolosis with swollen hands and feet. The skin condition had developed three days after the start of amoxicillin therapy. Laboratory tests at the time of admission indicated an infection. The diagnosis was 'acute generalised exanthematous pustulosis' (AGEP). During treatment with a soothing lotion, lasting one week, the patient improved and the skin condition disappeared. AGEP is characterised by acute onset of a pustular eruption in association with fever. It is usually seen after the use of drugs. This is an uncommon disease in children.

    Background: Acute ischemic stroke caused by internal carotid artery (ICA) occlusion usually has a poor prognosis, especially the T occlusion cases without functional collaterals. The efficacy of intravenous (IV) or intra-arterial (IA) thrombolysis with recombinant tissue plasminogen activator (rt-PA) remains ambiguous in these patients. Eendovascular recanalization of the occluded carotid has been attempted in recent years as a potential strategy. However, the different etiologies of ICA occlusion pose a significant challenge to neurointerventionists. Recently, several endovascular evolvements have been reported in treating carotid occlusion-related stroke. This review summarizes the current status of treatment for acute ICA occlusion.

    Human experimental challenge studies with influenza virus infection and controlled intervention trials have demonstrated beyond doubt the role of influenza virus infection in the pathogenesis of acute otitis media. Influenza virus infections not only disrupt eustachian tube function, but also impair recovery from infection and facilitate attachment of bacterial pathogens to respiratory epithelial cells. Immunization of young children with either inactivated or live, attenuated influenza vaccine will significantly reduce the incidence of acute otitis media. Early treatment of influenza with antiviral medication will reduce eustachian tube dysfunction that results from influenza virus infection. Influenza produces high morbidity in children that could be averted by universal immunization with attenuated nasal spray vaccine.

    Background. There is an international epidemic of hepatitis C virus (HCV) infection among human immunodeficiency virus (HIV)–infected men who have sex with men. Sustained virologic response (SVR) rates with pegylated interferon and ribavirin treatment are higher in these men during acute HCV than during chronic HCV, but treatment is still lengthy and SVR rates are suboptimal. Methods. We performed a pilot study of combination therapy with telaprevir, pegylated interferon, and ribavirin in acute genotype 1 HCV infection in HIV-infected men. Men who were treated prior to the availability of, or ineligible for, telaprevir were the comparator group. The primary endpoint was SVR12, defined as an HCV viral load <5 IU/mL at least 12 weeks after completing treatment. Results. In the telaprevir group, 84% (16/19) of men achieved SVR12 vs 63% (30/48) in the comparator group. Among men with SVR, median time to undetectable viral load was week 2 in the telaprevir group vs week 4 in the comparator group, and 94% vs 53% had undetectable viral loads at week 4. Most patients (81%) who achieved SVR in the telaprevir group received ≤12 weeks of treatment and there were no relapses after treatment. The overall safety profile was similar to that known for telaprevir-based regimens. Conclusions. Incorporating telaprevir into treatment of acute genotype 1 HCV in HIV-infected men halved the treatment duration and increased the SVR rate. Larger studies should be done to confirm these findings. Clinicians should be alert to detect acute HCV infection of HIV-infected men to take advantage of this effective therapy and decrease further transmission in this epidemic. PMID:24336914

    Nanofluids have been investigated regarding their advantages and potentialities for the purpose of increasing convective heat transfer rates inside thermal systems where they are used as working fluids. Researchers in thermophysics have investigated these fluids experimentally and numerically. This review provides extensive theoretical information concerning nanofluids in the single-phase and two-phase treatments. Important published works on nanofluid properties and correlations are summarized and reviewed in detail. Heat transfer enhancement by nanofluids is a challenging problem due to the difficulties inherent in the model of the physical mechanism of interaction between the paricles. Here the interaction between the phases is modeled by several two-phase models, and the results are given in graphical and tabular forms. Despite the advantages of the mixture model, such as imlementation of physical properties and less computational power requirements, some studies showed that the results of the single-phase and two-phase models are very similar. The main difference consists in the effect of the drift velocities of the phases relative to each other.

Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including three randomized trials. We combined the evidence using meta-analysis and generated a summary of findings table following the GRADE approach. We concluded the use of honey probably decreases the severity and frequency of cough, improves the quality of parent's and patient's sleep, and does not have side effects. PMID:27280298

    Regional analgesia, opioids, and several oral analgesics are commonly used for the treatment of acute pain after breast cancer surgery. While all of these treatments can suppress the acute postsurgical pain, there is growing evidence that suggests that the postsurgical comorbidity will differ in accordance with the type of analgesic used during the surgery. Our current study reviewed the effect of analgesics used for acute pain treatments on the major comorbidities that occur after breast cancer surgery. A considerable number of clinical studies have been performed to investigate the relationship between the acute analgesic regimen and common comorbidities, including inadequate quality of recovery after the surgery, persistent postsurgical pain, and cancer recurrence. Previous studies have shown that the choice of the analgesic modality does affect the postsurgical comorbidity. In general, the use of regional analgesics has a beneficial effect on the occurrence of comorbidity. In order to determine the best analgesic choice after breast cancer surgery, prospective studies that are based on a clear definition of the comorbidity state will need to be undertaken in the future.

    Triptans and analgetic nonsteroidal inflammatory drugs reduce acute pain syndromes in migraine. A further treatment option for an acute headache attack in patients with migraine may be the application of cyclooxygenase-2-specific inhibitors, as they have anti-inflammatory and analgesic properties. The objective of this pilot study was to investigate the effects of an oral fast-dissolving tablet of 10 mg of rizatriptan, an intravenous infusion of 40 mg of parecoxib, and a subcutaneous pen injection of sumatriptan (6 mg/0.5 mL) on pain relief in 3 cohorts of patients with episodic migraine. They were treated owing to the acute onset of a pain attack as a case of emergency. They were randomized to treatment with sumatriptan, rizatriptan, or parecoxib. The participants completed a visual analog scale for pain intensity at baseline before the drug administration and then after intervals of 20, 30, 60, and 120 minutes. Rizatriptan, parecoxib, and sumatriptan reduced pain symptoms. Twenty and 30 minutes after drug intake, rizatriptan was more efficacious than parecoxib and sumatriptan, and parecoxib was more effective than sumatriptan. Only a significant difference between rizatriptan and sumatriptan was found after 60 and 120 minutes. This trial demonstrates the effectiveness of a parecoxib infusion in the treatment of acute migraine and that the circumvention of the first pass effect of the liver by rizatriptan may be beneficial for fast pain relief.

    Acupuncture is an ancient medical treatment that is increasingly attracting the interest of the public. It is a complementary therapy that is widely used for management of pain, especially chronic discomfort caused by migraine, low-back pain and osteoarthritis of the knee(¹⁻³). The evidence base for the effectiveness of acupuncture and its clinical applications is controversial, and although its efficacy and safety in the management of acute pain have been demonstrated, the quality of this modality is still questionable. The present study reports a case of acute ankle injury, which was treated with acupuncture. A 33-year-old man presented with acute twisted ankle injury. He had pain with swelling around the ankle, and he was experiencing difficulty in walking. His clinical diagnosis was acute ankle sprain with severe pain. Several drug treatments are used for pain control, but in this case, we used acupuncture. After treatment, his pain diminished significantly with a decrease in VAS pain level from 8 to 4 in 20 minutes. At follow-up after one month, we found no skin infection in this case. PMID:27266242

The purpose of this study is to evaluate the temporal alterations of neural activities using electroencephalography (EEG) from the acute phase to the chronic phase, and to compare EEG with the degree of post-stroke motor function recovery in a rat model of focal ischemic stroke. Male Sprague-Dawley rats were subjected to 90 min transient middle cerebral artery occlusion surgery followed by reperfusion for seven days (n = 58). The EEG signals were recorded at the pre-stroke phase (0 h), acute phase (3, 6 h), subacute phase (12, 24, 48, 72 h) and chronic phase (96, 120, 144, 168 h) (n = 8). This study analyzed post-stroke seizures and polymorphic delta activities (PDAs) and calculated quantitative EEG parameters such as the alpha-to-delta ratio (ADR). The ADR represented the ratio between alpha power and delta power, which indicated how fast the EEG activities were. Forelimb and hindlimb motor functions were measured by De Ryck's test and the beam walking test, respectively. In the acute phase, delta power increased fourfold with the occurrence of PDAs, and the histological staining showed that the infarct was limited to the striatum and secondary sensory cortex. In the subacute phase, the alpha power reduced to 50% of the baseline, and the infarct progressed to the forelimb cortical region. ADRs reduced from 0.23 ± 0.09 to 0.04 ± 0.01 at 3 h in the acute phase and gradually recovered to 0.22 ± 0.08 at 168 h in the chronic phase. In the comparison of correlations between the EEG parameters and the limb motor function from the acute phase to the chronic phase, ADRs were found to have the highest correlation coefficients with the beam walking test (r = 0.9524, p < 0.05) and De Ryck's test (r = 0.8077, p < 0.05). This study measured EEG activities after focal cerebral ischemia and showed that functional recovery was closely

    Background Asylum seekers and refugees have been claimed to be at increased risk of developing complex posttraumatic stress disorder (complex PTSD). Consequently, it has been recommended that refugees be treated with present-centred or phased treatment rather than stand-alone trauma-focused treatment. This recommendation has contributed to a clinical practice of delaying or waiving trauma-focused treatment in refugees with PTSD. Objective The aim of this debate piece is to defend two theses: (1) that complex trauma leads to complex PTSD in a minority of refugees only and (2) that trauma-focused treatment should be offered to all refugees who seek treatment for PTSD. Methods The first thesis is defended by comparing data on the prevalence of complex PTSD in refugees to those in other trauma-exposed populations, using studies derived from a systematic review. The second thesis is defended using conclusions of systematic reviews and a meta-analysis of the efficacy of psychotherapeutic treatment in refugees. Results Research shows that refugees are more likely to meet a regular PTSD diagnosis or no diagnosis than a complex PTSD diagnosis and that prevalence of complex PTSD in refugees is relatively low compared to that in survivors of childhood trauma. Effect sizes for trauma-focused treatment in refugees, especially narrative exposure therapy (NET) and culturally adapted cognitive-behaviour therapy (CA-CBT), have consistently been found to be high. Conclusions Complex PTSD in refugees should not be assumed to be present on the basis of complex traumatic experiences but should be carefully diagnosed using a validated interview. In line with treatment guidelines for PTSD, a course of trauma-focused treatment should be offered to all refugees seeking treatment for PTSD, including asylum seekers. PMID:26886486

    In spite of the benefits of buprenorphine-naloxone co-formulation (BNX) in opioid maintenance treatment, the naloxone component has not prevented parenteral use of BNX. Current laboratory methods are not sufficient to differentiate between therapeutic and illicit use of buprenorphine, and little is known about urine naloxone concentrations. Measurement of urine naloxone, together with buprenorphine and norbuprenorphine, might help to determine the naloxone source and administration route. A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for this purpose. Naloxone, buprenorphine, and norbuprenorphine total concentrations were measured in urine samples from opioid-dependent patients before and during stable and unstable phases of maintenance treatment with BNX. The limit of quantification in urine was 1.0 µg/L for naloxone, buprenorphine and norbuprenorphine. Before treatment, all samples contained buprenorphine but the median naloxone concentration was 0 µg/L. During the maintenance treatment with BNX all urine samples were positive for naloxone, buprenorphine and norbuprenorphine. The naloxone concentration at a stable phase of treatment (median 60 µg/L, range 5-200 µg/L) was not different from the naloxone concentration at an unstable phase (70 µg/L, 10-1700 µg/L). Applying an upper limit of 200 µg/L to the sample, the median naloxone/buprenorphine ratio was higher in the high than in the low naloxone concentration group (0.9 vs 0.3, respectively). This study suggests that naloxone in urine can act as an indicator of compliance with BNX. Parenteral use of BNX was associated with a high naloxone/buprenorphine ratio. Negative naloxone with positive buprenorphine suggests the use/abuse of buprenorphine alone. PMID:23512803

    Anhedonia is one of the core symptoms of depression and has been linked to blunted responses to rewarding stimuli in striatal regions. Stress, a key vulnerability factor for depression, has been shown to induce anhedonic behavior, including reduced reward responsiveness in both animals and humans, but the brain processes associated with these effects remain largely unknown in humans. Emerging evidence suggests that stress has dissociable effects on distinct components of reward processing, as it has been found to potentiate motivation/‘wanting’ during the anticipatory phase but reduce reward responsiveness/‘liking’ during the consummatory phase. To examine the impact of stress on reward processing, we used a monetary incentive delay (MID) task and an acute stress manipulation (negative performance feedback) in conjunction with functional magnetic resonance imaging (fMRI). Fifteen healthy participants performed the MID task under no-stress and stress conditions. We hypothesized that stress would have dissociable effects on the anticipatory and consummatory phases in reward-related brain regions. Specifically, we expected reduced striatal responsiveness during reward consumption (mirroring patterns previously observed in clinical depression) and increased striatal activation during reward anticipation consistent with non-human findings. Supporting our hypotheses, significant Phase (Anticipation/Consumption) x Stress (Stress/No-stress) interactions emerged in the putamen, nucleus accumbens, caudate and amygdala. Post-hoc tests revealed that stress increased striatal and amygdalar activation during anticipation but decreased striatal activation during consumption. Importantly, stress-induced striatal blunting was similar to the profile observed in clinical depression under baseline (no-stress) conditions in prior studies. Given that stress is a pivotal vulnerability factor for depression, these results offer insight to better understand the etiology of this

    The outcome of intracerebral hemorrhage (ICH) is mainly determined by the volume of the hemorrhage core and the secondary brain damage to penumbral tissues due to brain swelling, microcirculation disturbance and inflammation. The present study aims to investigate the protective effects of cerebrolysin on brain edema and inhibition of the inflammation response surrounding the hematoma core in the acute stage after ICH. The ICH model was induced by administration of type VII bacterial collagenase into the stratum of adult rats, which were then randomly divided into three groups: ICH + saline; ICH + Cerebrolysin (5 ml/kg) and sham. Cerebrolysin or saline was administered intraperitoneally 1 h post surgery. Neurological scores, extent of brain edema content and Evans blue dye extravasation were recorded. The levels of pro-inflammatory factors (IL-1β, TNF-α and IL-6) were assayed by Real-time PCR and Elisa kits. Aquaporin-4 (AQP4) and tight junction proteins (TJPs; claudin-5, occludin and zonula occluden-1) expression were measured at multiple time points. The morphological and intercellular changes were characterized by Electron microscopy. It is found that cerebrolysin (5 ml/kg) improved the neurological behavior and reduced the ipsilateral brain water content and Evans blue dye extravasation. After cerebrolysin treated, the levels of pro-inflammatory factors and AQP4 in the peri-hematomal areas were markedly reduced and were accompanied with higher expression of TJPs. Electron microscopy showed the astrocytic swelling and concentrated chromatin in the ICH group and confirmed the cell junction changes. Thus, early cerebrolysin treatment ameliorates secondary injury after ICH and promotes behavioral performance during the acute phase by reducing brain edema, inflammatory response, and blood-brain barrier permeability.

    This study was conducted to evaluate the anti-diarrhoeal activity of Bacillus clausii strain UBBC 07 in patients suffering from acute diarrhoea. A total of 27 patients (average age of 35.44±8.08 years) with acute diarrhoea were included in a prospective, Phase II clinical study after informed consent and ethical committee approval. The criteria included for all subjects were ≥3 loose stool motions within 24 hours and for more than 7 days. All patients were assigned to receive one capsule of B. clausii strain UBBC-07 (containing 2×109 cfu) two times a day for a period of 10 days. Efficacy assessment of duration of diarrhoea, frequency of defecation, abdominal pain and stool consistency were tested on days 1, 3, 6 and 10. Safety was evaluated by assessing the incidence and type of adverse effects such as increase in blood pressure and pulse rate, physical examination and clinical laboratory tests, i.e. complete blood count, serum glutamic pyruvic transaminase, serum creatinine, and stool examination and microscopy, on day 1 and day 10. The results of this study clearly showed that the mean duration of diarrhoea decreased from 34.81±4.69 to 9.26±3.05 (P<0.0001) min per day, the frequency of defecation also decreased from 6.96±1.05 to 1.78±0.50 (P<0.0001) times per day, abdominal pain decreased from 3.22±0.93 (severe) to 0.74±0.71 (absent) (P<0.0001), and stool consistency improved from 3.93±0.38 (watery) to 1.22±0.42 (soft) (P<0.0001). No significant change in safety parameters were observed during treatment. This study shows that the B. clausii strain UBBC-07 can potentially be effective in alleviating the symptoms of diarrhoea without causing any adverse effects. PMID:23443952

    There have been major advances in our understanding of the multiple interactions between malignant cells and the innate and adaptive immune system. While the attention of immunologists has hitherto focused on solid tumors, the specific immunobiology of acute leukemias is now becoming defined. These discoveries have pointed the way to immune interventions building on the established graft-versus-leukemia (GVL) effect from hematopoietic stem-cell transplant (HSCT) and extending immunotherapy beyond HSCT to individuals with acute leukemia with a diversity of immune manipulations early in the course of the leukemia. At present, clinical results are in their infancy. In the coming years larger studies will better define the place of immunotherapy in the management of acute leukemias and lead to treatment approaches that combine conventional chemotherapy, immunotherapy and HSCT to achieve durable cures.

    PURPOSE The objective of this study was to assess the frequencies of ultrasound findings in patients with acute rotator cuff disorders in family medicine. METHODS In a prospective observational study, 129 patients aged 18 to 65 years with acute shoulder pain in whom the family physician suspected rotator cuff disease underwent ultrasound imaging. RESULTS Rotator cuff disease was present in 81% of the patients, and 50% of them had multiple disorders. Calcific tendonitis was the most frequently diagnosed specific disorder. An age of 40 years or older was most strongly related to rotator cuff disease. CONCLUSIONS Ultrasound imaging enables family physicians to rationalize treatment in nearly all patients who are aged 40 years and older with acute shoulder pain. PMID:25583893

    Small bowel obstruction (SBO) is a common clinical syndrome caused mainly by postoperative adhesions. In complement to clinical and biological evaluations, CT scan has emerged as a valuable imaging modality and may provide reliable information. The early recognition of signs suggesting bowel ischemia is essential for urgent operation. However appropriate management of SBO remains a common clinical challenge. Although a conservative approach can be successful in a substantial percentage of selected patients, regular and close re-assessement is mandatory. Any persistance or progression of the critical symptoms and signs should indeed lead to surgical exploration. Here we review the principles of adhesive SBO management and suggest a decision procedure for conservative versus surgical treatment.

    Studies of microbial pathogens and the toxins they produce are important for determining the mechanisms by which they cause disease and spread throughout a population. Some bacteria produce secretory enterotoxins (such as choleratoxin or the heat-labile or stable enterotoxins produced by E. coli) that invade cells directly. Others produce cytotoxins (such as those produced by Shigella, enteroinvasive E. coli, or C. difficile) that damage cells or trigger host responses that cause small or large bowel diseases (such as enteroaggregative or enteropathogenic E. coli or Salmonella). Viruses (such as noroviruses and rotaviruses) and protozoa (such as Cryptosporidium, Giardia or Entameba histolytica) disrupt cell functions and cause short- or long-term disease. Much epidemiological data about these pathogens have been collected from community- and hospital-acquired settings, as well from patients with traveler’s or persistent diarrhea. These studies have led to practical approaches for prevention, diagnosis and treatment. PMID:19457416

  14. A review of acute cyanide poisoning with a treatment update.

    Cyanide causes intracellular hypoxia by reversibly binding to mitochondrial cytochrome oxidase a(3). Signs and symptoms of cyanide poisoning usually occur less than 1 minute after inhalation and within a few minutes after ingestion. Early manifestations include anxiety, headache, giddiness, inability to focus the eyes, and mydriasis. As hypoxia progresses, progressively lower levels of consciousness, seizures, and coma can occur. Skin may look normal or slightly ashen, and arterial oxygen saturation may be normal. Early respiratory signs include transient rapid and deep respirations. As poisoning progresses, hemodynamic status may become unstable. The key treatment is early administration of 1 of the 2 antidotes currently available in the United States: the well-known cyanide antidote kit and hydroxocobalamin. Hydroxocobalamin detoxifies cyanide by binding with it to form the renally excreted, non-toxic cyanocobalamin. Because it binds with cyanide without forming methemoglobin, hydroxocobalamin can be used to treat patients without compromising the oxygen-carrying capacity of hemoglobin.

    Compartment syndrome can be difficult to diagnose in a child, with delays in diagnosis leading to disastrous outcomes. Thirty-six cases of compartment syndrome in 33 pediatric patients were treated at the authors' institution from January 1, 1992, to December 31, 1997. There were 27 boys and 6 girls, with nearly equal upper and lower extremity involvement. Approximately 75% of these patients developed compartment syndrome in the setting of fracture. Pain, pallor, paresthesia, paralysis, and pulselessness were relatively unreliable signs and symptoms of compartment syndrome in these children. An increasing analgesia requirement in combination with other clinical signs, however, was a more sensitive indicator of compartment syndrome: all 10 patients with access to patient-controlled or nurse-administered analgesia during their initial evaluation demonstrated an increasing requirement for pain medication. With early diagnosis and expeditious treatment, >90% of the patients studied achieved full restoration of function.

    Serum amyloid A protein (SAA) surges 1,000-fold in the blood of acute-phase animals, and yet its function during these acute events remains unknown. We report herein that SAA stimulates a developmental program in cultured NRK-52E cells that culminates in differentiated and functional tubules that feature a proximal tubule phenotype. We also found strong SAA expression in states of tubule formation (in utero stage) and regeneration (recovery from ischemia-reperfusion injury). These data lend support to a novel view of a more localized renal acute-phase reaction, where renal SAA may act as a paracrine or autocrine molecule that promotes tubule formation during development and repair.

    Between May 1980 and April 1987, 49 children with acute lymphoblastic leukemia (ALL) in isolated testicular and first leukemia relapse (ITR) were enrolled in the Associazione Italiana Ematologia ed Oncologia Pediatrica (AIEOP) multicenter study REC80-ITR. According to the Rome Workshop criteria, 77% were at standard and 23% at high initial prognostic risk. In 33% of the cases, ITR occurred during first treatment. The REC80-ITR protocol consisted of an induction phase regimen of vincristine (VCR), cytarabine (ARA-C), methotrexate (MTX), and asparaginase (L-asp), and bilateral testicular irradiation, and CNS prophylaxis with intrathecal MTX and a maintenance phase with a multidrug rotating regimen. Total treatment duration was 30 months. The median time of observation after ITR was 51 months. The Kaplan-Meier estimates of survival and disease-free survival (DFS) at 4 years were 67.7% and 41%, respectively. Patients who had an ITR on therapy or within the first off-therapy year showed the poorest outcome. The DFS at 3 years was 20%, 47.6%, and 100%, respectively, for children who had an ITR on treatment (n = 16), within the first year of treatment withdrawal (n = 22), or later (n = 10) (P = .001). Patients with an asymptomatic occult testicular infiltrate at treatment discontinuation had a very unfavorable prognosis. Eighty-one percent of second relapses involved the bone marrow. In our experience, children presenting an early ITR (ie, within 6 months of treatment withdrawal) need a very aggressive treatment because of the high probability of an underlying systemic disease. On the other hand, patients with a late ITR seem to have a truly local recurrence and can apparently be cured by standard protocols, as shown in protocol REC80-ITR.

    Acute promyelocytic leukemia (APL) is an uncommon subtype of acute myelogenous leukemia characterized by the proliferation of blasts with distinct morphology, a specific balanced reciprocal translocation t(15;17), and life-threatening hemorrhage caused mainly by enhanced fibrinolytic-type disseminated intravascular coagulation (DIC). The introduction of all-trans retinoic acid (ATRA) into anthracycline-based induction chemotherapy regimens has dramatically improved overall survival of individuals with APL, although hemorrhage-related death during the early phase of therapy remains a serious problem. Moreover, population-based studies have shown that the incidence of early death during induction chemotherapy is nearly 30 %, and the most common cause of death is associated with hemorrhage. Thus, development of a novel treatment strategy to alleviate abnormal coagulation in APL patients is urgently required. Recombinant human soluble thrombomodulin (rTM) comprises the active extracellular domain of TM, and has been used for treatment of DIC since 2008 in Japan. Use of rTM in combination with remission induction chemotherapy, including ATRA, produces potent resolution of DIC without exacerbation of bleeding tendency in individuals with APL. This review article discusses the pathogenesis and features of DIC caused by APL, as well as the possible anticoagulant and anti-leukemic action of rTM in APL patients.

    Background The diagnosis of Chagas disease is complex due to the dynamics of parasitemia in the clinical phases of the disease. The molecular tests have been considered promissory because they detect the parasite in all clinical phases. Trypanosoma cruzi presents significant genetic variability and is classified into six Discrete Typing Units TcI-TcVI (DTUs) with the emergence of foreseen genotypes within TcI as TcIDom and TcI Sylvatic. The objective of this study was to determine the operating characteristics of molecular tests (conventional and Real Time PCR) for the detection of T. cruzi DNA, parasitic loads and DTUs in a large cohort of Colombian patients from acute and chronic phases. Methodology/Principal Findings Samples were obtained from 708 patients in all clinical phases. Standard diagnosis (direct and serological tests) and molecular tests (conventional PCR and quantitative PCR) targeting the nuclear satellite DNA region. The genotyping was performed by PCR using the intergenic region of the mini-exon gene, the 24Sa, 18S and A10 regions. The operating capabilities showed that performance of qPCR was higher compared to cPCR. Likewise, the performance of qPCR was significantly higher in acute phase compared with chronic phase. The median parasitic loads detected were 4.69 and 1.33 parasite equivalents/mL for acute and chronic phases. The main DTU identified was TcI (74.2%). TcIDom genotype was significantly more frequent in chronic phase compared to acute phase (82.1% vs 16.6%). The median parasitic load for TcIDom was significantly higher compared with TcI Sylvatic in chronic phase (2.58 vs.0.75 parasite equivalents/ml). Conclusions/Significance The molecular tests are a precise tool to complement the standard diagnosis of Chagas disease, specifically in acute phase showing high discriminative power. However, it is necessary to improve the sensitivity of molecular tests in chronic phase. The frequency and parasitemia of TcIDom genotype in chronic

    Background: Research continues to develop novel therapeutic modalities that particularly focus on the pathogenesis of acute pancreatitis. This study aimed to assess the effects of diclofenac sodium and octreotide, alone or in combination, on pancreatic enzymes, pancreatic myeloperoxidase activity, histopathology and apoptosis of pancreas cells, using a model of experimentally induced acute pancreatitis. Objectives: We aimed to demonstrate effects of diclofenac sodium, octreotide and their combined use on pancreatic enzymes, activity of pancreatic myeloperoxidase (MPO) activity, histopathology and apoptosis of pancreas on treatment of caerulin-induced experimental acute pancreatitis. Materials and methods: Caerulin-induced acute pancreatitis model was created using a total of 58 male BALB-C mice of 25 gr in seven groups. Serum amylase, lipase levels and pancreatic myeloperoxidase activity were examined as well as apoptotic values in pancreatic acinar cells through TUNNEL method. Histopathology of pancreas was evaluated for presence of edema, hemorrhage, parenchymal necrosis, fat necrosis, leukocyte infiltration, and fibrosis. Results: In the diclofenac sodium group, apoptotic values in the pancreatic acinar cells were found to be statistically lower than in the acute pancreatitis group in terms of parenchymal necrosis and hemorrhage scores (P = 0.007, P = 0.002, and P = 0.052, respectively). No statistically significant differences were found in serum level of amylase, lipase, pancreatic myeloperoxidase activity and the other histopathological scores (P > 0.05). Conclusion: Diclofenac sodium, a cost-effective agent with a favorable side-effect profile, may represent a novel therapeutic agent for the treatment of acute pancreatitis. Findings of this study suggest a better efficacy for diclofenac sodium monotherapy as compared to octreotide alone or octreotide/diclofenac combination. PMID:26770346

    The circadian timing system (CTS) provides internal and external temporal coordination of an animal's physiology and behavior. In mammals, the generation and coordination of these circadian rhythms is controlled by a neural pacemaker, the suprachiasmatic nucleus (SCN), located within the hypothalamus. The pacemaker is synchronized to the 24 hour day by time cures (zeitgebers) such as the light/dark cycle. When an animal is exposed to an environment without time cues, the circadian rhythms maintain internal temporal coordination, but exhibit a 'free-running' condition in which the period length is determined by the internal pacemaker. Maintenance of internal and external temporal coordination are critical for normal physiological and psychological function in human and non-human primates. Exposure to altered gravitational environments has been shown to affect the amplitude, mean, and timing of circadian rhythms in species ranging from unicellular organisms to man. However, it has not been determined whether altered gravitational fields have a direct effect on the neural pacemaker, or affect peripheral parameters. In previous studies, the ability of a stimulus to phase shift circadian rhythms was used to determine whether a stimulus has a direct effect on the neural pacemaker. The present experiment was performed in order to determine whether acute exposure to a hyperdynamic field could phase shift circadian rhythms.

    Although individuals with sickle cell anaemia (SCA) have elevated baseline inflammation and endothelial activation, the acute phase response to maximal exercise has not been evaluated among children with SCA. We measured the acute phase response to maximal exercise testing for soluble vascular cell adhesion molecule (sVCAM) as well as interleukin 6 (IL6), total white blood cell (WBC) count, C-reactive protein (CRP) and D-dimer in a cohort of children with SCA and matched controls at baseline, immediately after, and 30, 60 and 120 min following exercise. Despite higher baseline levels of all biomarkers except CRP, the acute phase response from baseline to immediately after exercise was significantly greater in subjects versus controls for CRP (2·1 vs. 0·2 mg/l, P = 0·02) and D-dimer (160 vs. 10 μg/l, P < 0·01) only. Similar between-group trends were observed over time for all biomarkers, including sVCAM, IL6, total WBC, CRP and D-dimer. Lower fitness, defined by peak oxygen consumption (VO2 ), was independently associated with greater acute phase responses to exercise for sVCAM. Our results suggest maximal exercise may not be associated with any greater escalation of endothelial activation or inflammation in SCA and provide preliminary biomarker evidence for the safety of brief, high-intensity physical exertion in children with SCA.

    Pneumococcal phase variation of 37 middle ear and 31 nasopharyngeal isolates obtained from children with acute otitis media was examined in the absence of intervening culture. The fraction of the opaque colonies was significantly higher in middle ear isolates than in nasopharyngeal isolates. The difference is probably the result of the pneumococci adapting to differential selective environments.

    The revision of the two phase treatment represents a golden standard in the treatment of infected endoprosthesis. Throughout this study, the results of 21 patients with an infected hip endoprosthesis treated in two phases have been processed, with the use of an antibiotic spacer, within the period of 2009 and 2012. Thereby, a unique protocol for diagnosis and treatment of infections has been applied to all the patients, which entails a preoperational x-ray image, laboratory findings (Se, CRP), as well as a puncture aspiration with a microbiological and biochemical examination of the aspirated fragments. The operational treatment consists of: taking a sample for microbiological and histopathological diagnosis, removal of the implanted endoprosthesis, excision of the avascular and necrotic tissue and installing an antibiotic spacer. Postoperatively, the patients are treated with a parenteral application of an antibiotics based on an antibiogram, throughout a period of two weeks, and later on an oral treatment, a combination of two antibiotics, depending on the antibiogram, within the following four to six weeks. After the appeasement of the local findings and the laboratory results, a revision with a removal of the antibiotic spacer and reimplantation of an endoprosthesis - revisional or primary has been conducted on the patients, depending on the bone deficit. The functionality of the joint is graded based on the Haris Hip Score. The patients are being observed postoperatively for a period of 12 to 36 months. A definite reimplantation has been applied to 20 patients, while one patient has been treated with a resection method. The Haris Hip Score was 45 preoperatively, and 80 postoperatively. The applied protocol of the treatment of infected endoprosthesis is effective in the eradication of the infection and the final reimplantation. PMID:27442385

  11. Treatment of Acute Low Pressure Pulmonary Edema in Dogs

    Severe pulmonary edema sometimes develops despite normal pulmonary capillary wedge pressure (Ppw). The equation describing net transvascular flux of lung liquid predicts decreased edema when hydrostatic pressure is reduced or when colloid osmotic pressure is increased in the pulmonary vessels. We tested these predictions in a model of pulmonary capillary leak produced in 35 dogs by intravenous oleic acid. 1 h later, the dogs were divided into five equal groups and treated for 4 h in different ways: (a) not treated, to serve as the control group (Ppw = 11.1 mm Hg); (b) given albumin to increase colloid osmotic pressure by 5 mm Hg (Ppw = 10.6 mm Hg); (c) ventilated with 10 cm H2O positive end-expiratory pressure (Peep) (transmural Ppw = 10.4 mm Hg); (d) phlebotomized to reduce Ppw to 6 mm Hg; (e) infused with nitroprusside, which also reduced Ppw to 6 mm Hg. Phlebotomy and nitroprusside reduced the edema in excised lungs by 50% (P< 0.001), but Peep and albumin did not affect the edema. Pulmonary shunt decreased on Peep and increased on nitroprusside, and lung compliance was not different among the treatment groups, demonstrating that these variables are poor indicators of changes in edema. Cardiac output decreased during the treatment period in all but the nitroprusside group, where Ppw decreased and cardiac output did not. We conclude that canine oleic acid pulmonary edema is reduced by small reductions in hydrostatic pressure, but not by increased colloid osmotic pressure, because the vascular permeability to liquid and protein is increased. These results suggest that low pressure pulmonary edema may be reduced by seeking the lowest Ppw consistent with adequate cardiac output enhanced by vasoactive agents like nitroprusside. Further, colloid infusions and Peep are not helpful in reducing edema, so they may be used in the lowest amount that provides adequate circulating volume and arterial O2 saturation on nontoxic inspired O2.

    Liver is the central organ of iron metabolism. During acute-phase-response (APR), serum iron concentration rapidly decreases. The current study aimed to compare expression and localization of iron transport protein ferroportin-1 (Fpn-1) and of other iron import proteins after experimental tissue damage induced by injecting turpentine oil in the hind limbs of rats and mice. Serum and spleen iron concentration decreased with an increase in total liver, cytoplasmic and nuclear iron concentration. In liver, mRNA amount of Fpn-1, Fpn-1a, Fpn-1b, HFE, hemojuvelin (HJV) and hephaestin (heph) genes showed a rapid decrease. Hepcidin, divalent metal transporter-1 (DMT-1), transferrin (Tf) and Tf-receptor-1 (TfR1), TfR-2 (TfR2) gene expression was increased. Western blot analysis of liver tissue lysate confirmed the changes observed at mRNA level. In spleen, a rapid decrease in gene expression of Fpn-1, Fpn-1a, Fpn-1b, DMT-1, Tf, TfR1 and TfR2, and an increase in hepcidin was observed. Immunohistochemistry of DMT-1 and TfR2 were mainly detected in the nucleus of rat liver and spleen, whereas TfR1 was clearly localized in the plasma membrane. Fpn-1 was mostly found in the nuclei of liver cells, whereas in spleen, the protein was mainly detected in the cell membrane. Western blot analysis of liver fractions confirmed immunohistochemical results. In livers of wild-type mice, gene expression of Fpn-1, Fpn-1a and Fpn-1b was downregulated, whereas hepcidin gene expression was increased. In contrast, these changes were less pronounced in IL-6ko-mice. Cytokine (IL-6, IL-1b and TNF-a) treatment of rat hepatocytes showed a downregulation of Fpn-1, Fpn-1a and Fpn-1b, and upregulation of hepcidin gene expression. Moreover, western blot analysis of cell lysate of IL-6-treated hepatocytes detected, as expected, an increase of a2-macroglobulin (positive acute-phase protein), whereas albumin (negative acute-phase protein) and Fpn-1 were downregulated. Our results demonstrate that liver

    Crises from the child and adolescent psychiatric point of view must be considered as unique or repeated moments of basic questioning of self-focused and relational perception. Hospitalisation if necessary depends on a well prepared social, legal, physical and cooperative framework. Patients, their family or social environment are in need of clarity, structure, and a professional counterpart willing to engage responsibly within an inpatient or--mostly--outpatient framework. He must adapt his diagnostic or therapeutic action to the patient's experience of fear, loss of orientation and insecurity. Then a crisis may be experienced like a bonding experience. Concerning the capacity of action confronted to psychiatric crisis the authors stress the importance of the scenic understanding, expressed symptoms and the acted-out crisis dynamics more than diagnostic classification. The diagnostic and decisive process of atunement to the patient in crisis is being described. A model for psychodynamic understanding of perception of and action towards crisis is proposed, which allows describing the interference between relational dynamics and intra-psychic conflicts leading to crisis. This can then be used as therapeutical focus for the crisis intervention or a consecutive psychotherapeutic treatment.

  14. Involvement of activated leukocytes in the regulation of plasma levels of acute phase proteins in microgravity simulation experiments

    Earth-based studies of microgravity effects showed the induction of the mechanisms of acute phase reaction (APR). APR comprises the transition of stress-sensitive protein kinases of macrophages and other responsive cells into the active state and the phosphorylation of transcription factors which in turn stimulate the production of acute-phase reaction cytokines. Leukocyte activation is accompanied by the acceleration of the formation of oxygen radicals which can serve a functional indice of leukocyte cell state. The series of events at acute phase response result in selective changes in the synthesis of a number of secretory blood proteins (acute phase proteins, APPs) in liver cells thus contributing the recovery of homeostasis state in the organism. Earlier experiment with head-down tilt showed the increase in plasma concentrations of two cytokine mediators of acute phase response, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) being the outcome of the activation of producer cells, foremost, leukocytes. In experiment with 4-day dry immersion chemiluminescent (ChL) reply of the whole blood samples to a test stimulus were studied along with the measurements of plasma levels of APPs, namely, alpha1-antitrypsin (alpha1-AT), alpha1-acid glycoprotein (alpha1-AGP), alpha2-macroglobulin (alpha2-M), ceruloplasmin (Cer), haptoglobin (Hp), C3-complement component (C3), C-reactive protein (CRP). Eight individuals aged 21.2 ± 3.2 years were the test subjects in the investigation. Protein studies showed a noticeable increase in the mean plasma levels of all APPs measured in experiment thus producing the evidence of the activation of acute phase response mechanisms while individual patterns revealed variability during the immersion period. The overall trends were similar to these in the previous immersion series. The augment in the strength of signal in stimulated light emission tests was higher after 1- and 2-day of immersion exposure than before the

    Abstract Statins have beneficial effects on cerebral circulation and brain parenchyma during ischemic stroke and reperfusion. The primary hypothesis of this randomized parallel trial was that treatment with 80 mg/day of atorvastatin administered early at admission after acute atherosclerotic ischemic stroke could reduce serum levels of markers of immune-inflammatory activation of the acute phase and that this immune-inflammatory modulation could have a possible effect on prognosis of ischemic stroke evaluated by some outcome indicators. We enrolled 42 patients with acute ischemic stroke classified as large arteries atherosclerosis stroke (LAAS) randomly assigned in a randomized parallel trial to the following groups: Group A, 22 patients treated with atorvastatin 80 mg (once-daily) from admission day until discharge; Group B, 20 patients not treated with atorvastatin 80 mg until discharge, and after discharge, treatment with atorvastatin has been started. At 72 hours and at 7 days after acute ischemic stroke, subjects of group A showed significantly lower plasma levels of tumor necrosis factor-α, interleukin (IL)-6, vascular cell adhesion molecule-1, whereas no significant difference with regard to plasma levels of IL-10, E-Selectin, and P-Selectin was observed between the 2 groups. At 72 hours and 7 days after admission, stroke patients treated with atorvastatin 80 mg in comparison with stroke subjects not treated with atorvastatin showed a significantly lower mean National Institutes of Health Stroke Scale and modified Rankin scores. Our findings provide the first evidence that atorvastatin acutely administered immediately after an atherosclerotic ischemic stroke exerts a lowering effect on immune-inflammatory activation of the acute phase of stroke and that its early use is associated to a better functional and prognostic profile.

    Coupled plasma filtration adsorption (CPFA) is an extracorporeal blood purification therapy based on non-specific pro- and anti-inflammatory mediator adsorption on a special resin cartridge coupled with continuous veno-venous haemofiltration or continuous veno-venous haemodiafiltration and is one of the emerging treatments for septic patients. However, in the literature, there are limited data about its efficacy in treating patients with acute diseases but without the traditional criteria for sepsis. We describe the case of a 43-year-old male who developed acute respiratory distress syndrome secondary to pneumonia and acute kidney injury, whose clinical conditions rapidly improved after early CPFA therapy.

    3F8 is an IgG3 murine monoclonal antibody directed against the ganglioside GD2. In a phase II study, 3F8 was administered i.v. to 16 patients (pts) who had stage 4 neuroblastoma. Response was seen in bony lesions (2 of 7 pts) and marrow (3 of 8 pts). Acute toxicities of pain, fever, urticaria, hypertension, hypotension and anaphylactoid reactions were self-limited and manageable. Three pts are long-term survivors between 79-130+ months after 3F8 treatment without additional systemic therapy and no delayed neurological complications. The potential benefits of 3F8 when added to chemoradio-therapy warrant further investigation.

    TAK-442 is an oral direct factor Xa inhibitor. We sought to determine the dose-dependent effect of TAK-442 on major bleeding when added to standard treatment in stabilised patients with acute coronary syndrome (ACS). In this phase II double-blind study, 2,753 ACS patients were randomised to TAK-442 or placebo in addition to usual care using a three-stage adaptive design. Patients were randomised to placebo in all stages, but doses of TAK-442 escalated from 10 mg BID, 20 mg twice-daily (BID), or 40 mg once-daily (QD) in stage 1; to 40 mg BID, 80 mg QD, or 80 mg BID in stage 2; and to 160 mg QD or 120 mg BID in stage 3. Study drug was started 36 hours after emergent treatment of ACS and within seven days of admission, and continued for 24 weeks. The primary endpoint was incidence of TIMI (thrombolysis in myocardial infarction) major bleeding. TIMI major bleeding incidence was low, but higher with the pooled TAK-442 doses than with placebo (17 [0.9%] vs 4 [0.5%]; p=0.47), although the difference was neither significant nor dose-dependent. However, a dose response was evident when using the modified ISTH scale. The incidence of cardiovascular events was similar among TAK-442 dose groups and placebo. When administered over a wide range of doses after an ACS event, TAK-442 treatment did not result in a dose-dependent increase in TIMI major bleeding, but increased bleeding was observed when a more sensitive bleeding scale was used. There was no evidence for efficacy.

    2014-03-01

    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.

    Purpose: To assess the feasibility and effectiveness of emergency endovascular treatment of acute arterial injuries after orthopedic surgery. Materials and Methods: Fifteen patients (mean age 68.3 years) with acute arterial injuries after orthopedic surgery were observed, in particular, 5 patients with pseudoaneurysm, 9 patients with active bleeding, and 1 patient with arterial dissection. Transarterial embolization (TAE) and positioning of covered and noncovered stents were the treatments performed. Follow-up after stent implantation (mean 36 months) was performed with color Doppler US (CDU) at 1, 3, 6, and 12 months and yearly thereafter. Plain X-ray was performed to evidence dislodgment or fracture of the graft. A minimum of 12 months' follow-up is available after TAE. Results: Immediate technical success was obtained in all cases. No major complications occurred. Overall clinical success rate was 100%. During mean follow-up, stent-graft occlusions did not occurred. No recurrence and/or consequence of TAE was registered during a minimum follow-up of 12 months. Conclusions: Percutaneous treatment is a feasible and safe tool for treating arterial injuries because it can provide fast and definitive resolution of the damage. This low-invasiveness approach can be proposed as first-line treatment in patients with acute injuries after orthopedic surgery.

    We performed a meta-analysis for systematic evaluation of the status quo of catheter thrombolysis for the treatment of acute lower limb deep vein thrombosis in China. We searched the China Biomedical bibliographic database (CBM), China National Knowledge Infrastructure (CNKI), Weipu full-text electronic journals, Wanfang full-text database, and Medline (1990 through June 2011) for clinical randomized controlled trials of catheter-directed thrombolysis and superficial venous thrombolysis to compare their efficacies for the treatment of acute deep vein thrombosis. The results were analyzed by using the Cochrane-recommended RevMan 4.2 software package, and the odds ratio (OR) was used as the combined measure of efficacy. The search retrieved 8 randomized controlled trials, and meta-analysis using the total rate of effective treatment as the clinical observation index found that the combined OR for the catheter thrombolysis group versus the superficial venous thrombolysis group was significant (P < 0.01; OR = 11.78; 95% confidence interval = 6.99-19.87). In conclusion, the meta-analysis indicated that catheter thrombolysis was more effective than superficial venous thrombolysis for the treatment of acute deep vein thrombosis in the lower limb in Chinese individuals. However, the included trials were only of medium quality, so more rational and scientific clinical trials are needed to validate this conclusion.

    In the past months significant new data have been published in the field of headache and migraine. With the publication of the second and revised version of the classification of headache disorders, new entities such as chronic migraine have been introduced. Moreover, the repertoire of drugs available for the treatment of migraine has changed as well. Whereas ergot derivatives have been almost completely taken off the market, seven triptans in 23 different preparations are now available and allow the physician to customize the treatment of acute attacks. CGRP antagonists, a completely new generation of anti-migraine compounds for the treatment of acute attacks, have now been tested successfully in clinical trials. For the prophylaxis of migraine, several agents that had been well established for decades have recently been taken off the market too, but new agents such as topiramate, which possesses different modes of action, have been tested successfully and are now available for the prophylaxis of migraine. The following review will summarize the newest developments in acute therapy and prophylactic treatment of migraine.

    This post hoc analysis of the DACO-016 phase III study evaluates the impact of decitabine on transfusion dependence and survival in 485 elderly patients with newly diagnosed acute myeloid leukemia (AML). Red blood cell (RBC) and platelet (PLT) transfusion independence, defined as no transfusions for ≥ 8 consecutive weeks, was measured in both decitabine (n = 242) and treatment choice (TC, n = 243) arms. More RBC transfusion dependent patients at baseline became transfusion independent with decitabine than with TC (26% vs. 13%; p = 0.0026). Similar results were obtained for patients who were PLT transfusion dependent at baseline (31% vs. 13%; p = 0.0069). When excluding patients who attained complete remission (CR), survival was improved in patients who achieved RBC or PLT transfusion independence, suggesting that reaching CR is not a prerequisite for deriving benefit from treatment with decitabine. In addition, patients who achieved transfusion independence with decitabine had increased treatment continuation, even in the absence of CR.

    Objective To assess whether the cognitive function in the acute stage evaluated by domain-specific neuropsychological assessments would be an independent predictor of functional outcome after stroke. Methods Forty patients underwent 4 domain-specific neuropsychological examinations about 3 weeks after the onset of stroke. The tests included the Boston Naming Test (BNT), the construction recall test (CRT), the construction praxis test (CPT), and the verbal fluency test (VFT). The Korean version of Modified Barthel Index (K-MBI) at 3 months and the modified Rankin Scale (mRS) at 6 months were investigated as functional outcome after stroke. Functional improvement was assessed using the change in K-MBI during the first 3 months and subjects were dichotomized into 'good status' and 'poor status' according to mRS at 6 months. The domain-specific cognitive function along with other possible predictors for functional outcome was examined using regression analysis. Results The z-score of CPT (p=0.044) and CRT (p<0.001) were independent predictors for functional improvement measured by the change in K-MBI during the first 3 months after stroke. The z-score of CPT (p=0.049) and CRT (p=0.048) were also independent predictors of functional status at post-stroke 6 months assessed by mRS. Conclusion Impairment in visuospatial construction and memory within one month after stroke can be an independent prognostic factor of functional outcome. Domain-specific neuropsychological assessments could be considered in patients with stroke in the acute phase to predict long-term functional outcome. PMID:27152270

    The prospectively assessed time course of changes in ventricular repolarization during acute myocardial infarction (AMI) is reported in 32 patients admitted 2.0 +/- 1.8 (SD) hours after AMI onset. The initial corrected QT interval (QTc) upon hospitalization was longer in the 14 patients developing ventricular tachycardia (VT) within the first 48 hours as compared to QTc in the eight patients with frequent ventricular premature beats (VPBs) and to QTc in the 10 patients with infrequent VPBs. By the fifth day after AMI onset, the QTc shortened significantly only in the VT group, suggesting a greater initial abnormality of repolarization in these patients. All 32 patients had coronary angiography, radionuclide ventriculography, and myocardial perfusion scintigraphy before hospital discharge. Significant discriminating factors related to early phase VT in AMI included initially longer QT and QTc intervals, faster heart rate, higher peak serum levels of creatine kinase, acute anterior infarction, angiographically documented proximal stenosis of the left anterior descending coronary artery, and scintigraphic evidence of hypoperfusion of the interventricular septum. Prior infarction, angina pectoris, hypertension, multivessel coronary artery disease, and depressed left ventricular ejection fraction did not provide discrimination among the three different ventricular arrhythmia AMI groups. Researchers conclude that (1) the QT interval is frequently prolonged early in AMI, (2) the initial transiently prolonged ventricular repolarization facilitates and predicts complex ventricular tachyarrhythmias within the first 48 hours of AMI, (3) jeopardized blood supply to the interventricular septum frequently coexists, and (4) therapeutic enhancement of rapid recovery of the ventricular repolarization process merits investigation for prevention of VT in AMI.

    Glycerol is a by-product of biodiesel produced by transesterification and is contained in the glycerol phase together with many other materials such as soaps, remaining catalyst, water, and esters formed during the process. The content of glycerol is approximately 30-60 wt.%. In this paper, treatments of the glycerol phase to obtain glycerol with a purity of 86 wt.% (without distillation) and a mixture of fatty acids with esters (1:1) or only a mixture of fatty acids with a purity of 99 wt.% are presented. The treatment was carried out by removing of alkaline substances and esters. Fatty acids were produced by saponification of the remaining esters and subsequent neutralization of alkaline substances by phosphoric, sulfuric, hydrochloric, or acetic acids. Salts are by-products and, in the case of phosphoric acid can be used as potash-phosphate fertilizer. The process of treatment is easy and environmentally friendly, because no special chemicals or equipment are required and all products are utilizable.

    A phase 1 study was conducted to evaluate the safety, pharmacokinetics (PK), efficacy and pharmacogenetic characteristics of clofarabine in seven Japanese pediatric patients with relapsed/refractory acute lymphoblastic leukemia (ALL). Patients in Cohort 1 received clofarabine 30 mg/m(2)/day for 5 days, followed by 52 mg/m(2)/day for 5 days in subsequent cycles. Cohort 2 patients were consistently treated with 52 mg/m(2)/day for 5 days. No more than six cycles were performed. Every patient had at least one ≥Grade 3 adverse event (AE). AEs (≥Grade 3) related to clofarabine were anaemia, neutropenia, febrile neutropenia, thrombocytopenia, alanine aminotransferase increased, aspartate aminotransferase increased, haemoglobin decreased, and platelet (PLT) count decreased. C max and AUC of clofarabine increased in a dose-dependent fashion, but its elimination half-life (T 1/2) did not appear to be dependent on dose or duration of treatment. Clofarabine at 52 mg/m(2)/day shows similarly tolerable safety and PK profiles compared to those in previous studies. No complete remission (CR), CR without PLT recovery, or partial remission was observed. Since clofarabine is already used as a key drug for relapsed/refractory ALL patients in many countries, the efficacy of clofarabine in Japanese pediatric patients should be evaluated in larger study including more patients, such as by post-marketing surveillance.

    The study aims to provide an updated assessment of the evidence for individual pharmacological therapies for acute migraine treatment. Pharmacological therapy is frequently required for acutely treating migraine attacks. The American Academy of Neurology Guidelines published in 2000 summarized the available evidence relating to the efficacy of acute migraine medications. This review, conducted by the members of the Guidelines Section of the American Headache Society, is an updated assessment of evidence for the migraine acute medications. A standardized literature search was performed to identify articles related to acute migraine treatment that were published between 1998 and 2013. The American Academy of Neurology Guidelines Development procedures were followed. Two authors reviewed each abstract resulting from the search and determined whether the full manuscript qualified for review. Two reviewers studied each qualifying full manuscript for its level of evidence. Level A evidence requires at least 2 Class I studies, and Level B evidence requires 1 Class I or 2 Class II studies. The specific medications - triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan [oral, nasal spray, injectable, transcutaneous patch], zolmitriptan [oral and nasal spray]) and dihydroergotamine (nasal spray, inhaler) are effective (Level A). Ergotamine and other forms of dihydroergotamine are probably effective (Level B). Effective nonspecific medications include acetaminophen, nonsteroidal anti-inflammatory drugs (aspirin, diclofenac, ibuprofen, and naproxen), opioids (butorphanol nasal spray), sumatriptan/naproxen, and the combination of acetaminophen/aspirin/caffeine (Level A). Ketoprofen, intravenous and intramuscular ketorolac, flurbiprofen, intravenous magnesium (in migraine with aura), and the combination of isometheptene compounds, codeine/acetaminophen and tramadol/acetaminophen are probably effective (Level B).

    Treatments for acute distal radioulnar joint (DRUJ) instability with distal radius fracture vary from conservative to operative treatment, although it seems to be no consensus regarding which treatment is optimal. This prospective randomized study was designed to compare the clinical outcomes for operative and conservative treatment of acute DRUJ instability with distal radius fracture, according to the presence or absence and type of ulnar styloid process fracture and the degree of its displacement. Between July 2008 and February 2013, we enrolled 157 patients who exhibited an unstable DRUJ during intraoperative manual stress testing (via the ballottement test) after fixation of the distal radius. Patients were classified according to the type of the ulnar styloid process fracture, using preoperative wrist radiography, and each group was divided into subgroups, according to their treatment method. We then compared the clinical outcomes between the conservative and operative treatments, using their range of motion; Disabilities of the Arm, Shoulder, and Hand score; modified Mayo wrist score; and grip strength. At 3 months after surgery, among patients without ulnar styloid process fracture, the flexion-extension range was 79 ± 15° after supination sugar-tong splinting (group A-1), 91 ± 14° after DRUJ transfixation (group A-2), and 89 ± 10° after arthroscopic triangular fibrocartilage complex repair (group A-3); the operative treatments provided greater joint motion ranges than conservative treatment. The groups with ulnar styloid process fractures at the tip (group B) or base (group C) also exhibited better clinical outcomes after the operative treatments, compared with after the conservative treatment. However, at the final follow-up, groups A-1, A-2, and A-3 exhibited similar flexion-extension ranges (122 ± 25°, 119° ± 18°, and 120° ± 16°, respectively) and modified Mayo wrist scores (87 ± 7, 89 ± 8, and 85 ± 9).

    Endoscopic biliary drainage has been established to provide effective treatment for acute obstructive jaundice and cholangitis. A recently developed ultrathin transnasal videoendoscope (TNE) is minimally invasive even for critically ill patients and can be performed without conscious sedation. Transnasal endoscopic biliary drainage (TNE-BD) is performed using a front-viewing TNE with approximately 5 mm outer diameter and 2 mm working channel diameter. Finally, 5F naso-biliary tube or plastic stent are placed. Technical success rates are approximately 100% and 70% for post-endoscopic sphincterotomy or placement of self-expandable metallic stent, and intact papilla, respectively. There are no serious complications. In conclusion, although further cases should be accumulated, TNE-BD and in particular, one-step naso-biliary drainage using TNE may be a useful and novel technique for the treatment of acute cholangitis.

    Essential oils are volatile and can have good antimicrobial activity. We compared the effects of oil of basil (Ocimum basilicum) and essential oil components (thymol, carvacrol, and salicylaldehyde) to those of a placebo when placed in the ear canal of rats with experimental acute otitis media caused by pneumococci or Haemophilus influenzae. Progress was monitored by otomicroscopic examination and middle ear cultures. The treatment with oil of basil or essential oil components cured or healed 56%-81% of rats infected with H. influenzae and 6%-75% of rats infected with pneumococci, compared with 5.6%-6% of rats in the placebo group. Essential oils or their components placed in the ear canal can provide effective treatment of acute otitis media. PMID:15871121

    Chondral and osteochondral fractures of the lower extremities are important injuries because they can cause pain and dysfunction and often lead to osteoarthritis. These injuries can be misdiagnosed initially which may impact on the healing potential and result in poor long-term outcome. This comprehensive review focuses on current pitfalls in diagnosing acute osteochondral lesions, potential investigative techniques to minimize diagnostic errors as well as surgical treatment options. Acute osteochondral fractures are frequently missed and can be identified more accurately with specific imaging techniques. A number of different methods can be used to fix these fractures but attention to early diagnosis is required to limit progression to osteoarthritis. These fractures are common with joint injuries and early diagnosis and treatment should lead to improved long term outcomes. PMID:26587063

    Two men aged 19 and 21 years ingested 1 g and 4 g respectively from 3 kg of a white crystalline powder that they thought was a substance of abuse. It was later identified as almost pure arsenic trioxide. Both had nausea and vomiting and one developed acute renal failure. Each was treated with 2,3-dimercaptopropanesulphonate (DMPS), and made a full recovery with no evidence of prolonged renal or neurological impairment. The DMPS-arsenic complex is probably associated with lower penetration into the CNS and as a consequence treatment with DMPS may result in lower acute and chronic neurotoxicity than treatment with the currently standard recommended chelating agent dimercaprol (British Anti-Lewisite; BAL).

    Relapse of acute lymphoblastic leukemia remains a major cause of death in patients following allogeneic hematopoietic stem cell transplantation. Several factors may affect the concurrence and outcome of relapse, which include graft-versus-host disease, minimal residual disease or intrinsic factors of the disease, and transplantation characteristics. The mainstay of relapse prevention and treatment is donor leukocyte infusions, targeted therapies, second transplantation, and other novel therapies. In this review, we mainly focus on addressing the impact of graft-versus-host disease on relapse and the prophylaxis and treatment of acute lymphoblastic leukemia relapse following allogeneic hematopoietic stem cell transplantation. We also make recommendations for critical strategies to prevent relapse after transplantation and challenges that must be addressed to ensure success. PMID:25709473

    The efficiency of a new peptide medicine-Prostatilen was studied when using it in acute postoperative retention of urine. Under observation there were 87 patients of 23-78 years of age after hemorrhoidectomy, plasty of the rectal sphincter or dissection of its fissure etc. The patients endured the treatment with Prostatilen well. Self-dependent urination was recovered during the nearest 40 min after injection of 5 mg of the medicine. In the treatment of 23 patients it was used prophylactically before the appearance of a micturate urge. In 14 of them the postoperative period was smooth, in 9 patients the self-dependent urination was recovered following one additional injection. Clinical observations confirm that Proctatilen has a regulating effect upon the bladder tone which allows it to be recommended as a medicine for prevention of acute reflex retention of urine after operations in the area of the rectal sphincter.

    To provide guidance to clinicians about best practices, the Wilderness Medical Society convened an expert panel to develop evidence-based guidelines for prevention and treatment of acute mountain sickness, high altitude cerebral edema, and high altitude pulmonary edema. These guidelines present the main prophylactic and therapeutic modalities for each disorder and provide recommendations about their role in disease management. Recommendations are graded based on the quality of supporting evidence and balance between the benefits and risks/burdens according to criteria put forth by the American College of Chest Physicians. The guidelines also provide suggested approaches to prevention and management of each disorder that incorporate these recommendations.

    It has been consistently observed that patients with renal dysfunction have more premature, severe, complicated, and fatal cardiovascular disease than age- and sex-matched individuals with normal renal function. There have been 4 major explanations for this finding: (1) positive confounding by third variables associated with chronic kidney disease (CKD), including diabetes mellitus and hypertension; (2) therapeutic nihilism or lesser use of beneficial therapies in CKD; (3) greater toxicities of therapies, such as bleeding from anticoagulants or contrast-induced kidney injury; (4) biological factors which result directly from CKD that work to promote and accelerate cardiovascular disease. In this paper, we focus on the issue of treatment disparities or therapeutic nihilism and its contribution to poor outcomes in the setting of acute coronary syndromes and acutely decompensated heart failure. This issue is important because if we can overcome barriers to the utilization of beneficial treatments, then clinical outcomes should improve over time.

    The aims of our experiments on animals were (i) to evaluate by direct oximery the efficiency of various antioxidant drugs in a complex treatment of acute pancreatitis and (ii) to determine the diagnostic value of the direct oximetry method for estimation of the efficiency of medical treatment. The article presents data obtained in a group 75 outbred Guinea with a model acute pancreatitis, which were treated with mexibel (group 1), emoxipin (group 2), end cytoflavin (group 3), with subsequent investigation of the pancreatic tissues by the direct oximetry method. The obtained results confirmed that the intraperitoneal injection of cytoflavin to animals stimulates tissue respiration, improves metabolism, promotes pancreas recovery, and also improves the prognosis and reduces the lethal outcome. The efficiency of cytoflavin within the complex therapy exceeds the effect of other antioxidants (mexibel and emoxipin) under otherwise equal conditions.

    2013-01-01

    Introduction Acute leukemia is rare in pregnancy. The importance of promptly diagnosing and treating this disease in pregnancy stems from its life-threatening potential, both to the mother and fetus. Case presentation We report a case of relapse of acute myeloid leukemia at 23 weeks of pregnancy in a 24-year-old Albanian woman. Our patient categorically refused chemotherapy treatment, and in her 35th week of gestation, severe hemorrhagic diathesis rapidly developed. The manifestation and course of this life-threatening complication posed therapeutic challenges for the attending medical team. Conclusion Based both on our experience and the results of other gynecological studies, there exists a strong indication that the earlier a patient’s chemotherapy treatment begins, the better the maternal outcome. We support chemotherapy for patients who are pregnant presenting with such illness. The present case report testifies that refusal of chemotherapy by such patients is a high-risk decision.

    Amoxicillin is a first-line antibiotic treatment for acute otitis media in children and one of the most commonly used antibiotics for human bacterial infections. We investigated changes in salivary bacterial communities among children treated with amoxicillin for acute otitis media (n = 18), using a culture-independent approach based on pyrosequencing of the V3 region of the bacterial 16S rRNA gene. The control group consisted of children with acute otitis media who were not given antibiotics (n = 15). One species-level phylotype assigned to the genus Streptococcus was identified across all (n = 99) saliva samples. Two additional species-level phylotypes from the genera Gemella and Granulicatella were shared by all (n = 45) samples of control subjects. Amoxicillin treatment resulted in reduced species richness and diversity, and a significant shift in the relative abundance of 35 taxa at different ranks from phylum to species-level phylotype. At the phylum level, prevalence of TM7 and Actinobacteria decreased at the end of treatment, whereas Proteobacteria had a higher relative abundance post-treatment. Multivariate analysis showed that samples from the same control subject taken over time intervals tended to cluster together. Among antibiotic-treated subjects, samples taken before and at the end of amoxicillin treatment formed two relatively well-separated clusters both of which greatly overlapped with samples taken about 3 weeks post-treatment. Our results point to a substantial but incomplete recovery of the salivary bacterial community from the antibiotic about 3 weeks after the end of treatment.

    Stress alters physiology and behavior across species. Most research on the effects of stress on behavior uses chronic stressors, and most are correlational. The effects of acute stressors on physiology and behavior have been mixed. Here, we use zebra finches, a highly gregarious species that forms long-term pair bonds, to test the effects of an acute corticosterone (CORT) on opposite-sex partner preferences over a same-sex individual or a group (the latter is a highly appealing option). We had two competing hypotheses. First, we predicted that acute CORT would alter preferences for the opposite sex bird in both conditions in both sexes. However, since there is a sex difference in the effects of CORT on partner preferences in voles, these effects may be more pronounced in males than in females. To test our hypotheses, we administered 2 doses of CORT (10μg and 20μg) or vehicle (control) using a repeated measures design. In the male vs. female test, there was a significant Sex by Treatment interaction, such that in males, 10μg CORT increased preferences for a female over the male compared to when these same males were treated with saline at baseline. There were no effects of treatment in females. In the opposite-sex vs. group condition, there was an overall effect of Treatment, such that the 10μg dose increased preference for the opposite-sex individual over both saline treatments, regardless of sex. These findings further our understanding of the effects of an acute stressor on sexual partner preferences.

  9. Role of somatostatin and its analogues in the treatment of acute and chronic pancreatitis.

    PubMed Central

    Acute pancreatitis is caused by the activation of digestive enzymes in the pancreas and a possible treatment, therefore, is the inhibition of enzyme secretion. This approach is somewhat controversial, however, as it is not clear whether pancreatic secretion continues to occur during the course of acute pancreatitis. Animal studies show an appreciable reduction of secretion in the inflamed pancreas, but studies in humans are not conclusive. The use of somatostatin or its analogue, octreotide, has been investigated in several clinical studies. A meta analysis of six individual studies in which somatostatin was given for acute pancreatitis showed that somatostatin significantly reduces mortality. A trial in patients with moderate to severe acute pancreatitis showed a lower rate (although not statistically significant) of complications in patients treated with 3 x 200 and 3 x 500 micrograms/day octreotide, compared with controls and patients receiving a lower dose of octreotide. A further study showed a significant reduction in patient controlled analgesics in patients treated with octreotide compared with controls. Pain is the important clinical symptom of chronic pancreatitis, possibly resulting from an increased intraductal pressure during secretion. The effect on pain of the inhibition of pancreatic secretion by octreotide has been investigated in two studies. One showed no significant reduction in pain after treatment with octreotide for three days. In the other, in which octreotide was used for three weeks, significantly less pain and analgesic use was recorded during octreotide treatment than during placebo. The most common complication of chronic pancreatitis is the formation of pseudocysts. There is some evidence that octreotide may be useful in their treatment. PMID:7911442

    The cerebellar glomerulus was studied by electron microscopic morphometry in female Wistar rats. Age-dependent alterations have been revealed from 3 to 28 mth of age, and the effect of centrophenoxine (CPH) was analyzed in two different patterns of administration. First, 27-mth-old rats were treated daily for 6 wk (acute treatment), and second, 18-mth-old rats were treated 3 times per week for 5 months (chronic treatment). The dose was 100 mg CPH/kg body weight, injected intraperitoneally. The surface density (SV), the numerical density (NV) and the average length (L) of the synaptic junctions were calculated from data obtained on ethanol-phosphotungstic acid stained ultrathin sections. An age-dependent reduction of SV and NV of the synaptic contact zones was found, and the L increased in the oldest animals. CPH-treatment resulted in a marked increase of SV in both types of application, whereas the other two parameters behaved differently in the two groups. The chronic treatment resulted in a significant slowing down of the decrease of NV, whereas L remained invariate. On the contrary, the acute treatment increased L but did not alter significantly NV. The results and the differences between the treatment types are discussed in terms of synaptic plasticity and are interpreted as different manifestations of the same reactive synaptogenetic process.

    Abdominal compartment syndrome (ACS) in patients with severe acute pancreatitis (SAP) is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach. There remains uncertainty about the most appropriate surgical technique for the treatment of ACS in SAP. Some unresolved questions remain including medical treatment, indications, timing, and interventional techniques. This review will focus on interventional treatment of this serious condition. First line therapy is conservative treatment aiming to decrease IAP and to restore organ dysfunction. If nonoperative measures are not effective, early abdominal decompression is mandatory. Midline laparostomy seems to be method of choice. Since it carries significant morbidity we need randomized studies to establish firm advantages over other described techniques. After ACS resolves efforts should be made to achieve early primary fascia closure. Additional data are necessary to resolve uncertainties regarding ideal timing and indication for operative treatment. PMID:26839539

    AIM: To study the effect of combined indwelling catheter, hemofiltration, respiration support and traditional Chinese medicine (e.g. Dahuang) in treating abdominal compartment syndrome of fulminant acute pancreatitis. METHODS: Patients with fulminant acute pancreatitis were divided randomly into 2 groups of combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring and routine conservative measures group (group 1) and control group (group 2). Routine non-operative conservative treatments including hemofiltration, respiration support, gastrointestinal TCM ablution were also applied in control group patients. Effectiveness of the two groups was observed, and APACHE II scores were applied for analysis. RESULTS: On the second and fifth days after treatment, APACHE II scores of group 1 and 2 patients were significantly different. Comparison of effectiveness (abdominalgia and burbulence relief time, hospitalization time) between groups 1 and 2 showed significant difference, as well as incidence rates of cysts formation. Mortality rates of groups 1 and 2 were 10.0% and 20.7%, respectively. For patients in group 1, celiac drainage quantity and intra-abdominal pressure, and hospitalization time were positively correlated (r = 0.552, 0.748, 0.923, P < 0.01) with APACHE II scores. CONCLUSION: Combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring, short veno-venous hemofiltration (SVVH), gastrointestinal TCM ablution, respiration support have preventive and treatment effects on abdominal compartment syndrome of fulminant acute pancreatitis.

    There are at least three distinct fracture patterns that occur in the proximal fifth metatarsal: tuberosity avulsion fractures, acute Jones fractures, and diaphyseal stress fractures. Each of these fracture patterns has its own mechanism of injury, location, treatment options, and prognosis regarding delayed union and nonunion. Tuberosity avulsion fractures are the most common in this region of the foot. The majority heal with symptomatic care in a hard-soled shoe. The true Jones fracture is an acute injury involving the fourth-fifth intermetatarsal facet. These injuries are best treated with non-weight-bearing cast immobilization for 6 to 8 weeks. The rate of successful union with this treatment has been reported to be between 72% and 93%. For the high-performance athlete with an acute Jones fracture, early intramedullary-screw fixation is an accepted treatment option. Nonacute diaphyseal stress fractures of the proximal fifth metatarsal and Jones fractures that develop into delayed unions and nonunions can both be managed with operative fixation with either closed axial intramedullary-screw fixation or autogenous corticocancellous grafting. Early results with the use of electrical stimulation are promising; however, prospective studies are needed to better define the role of this modality in managing these injuries.

    Despite the advances in understanding the pathophysiology of acute myeloid leukaemia (AML), the cure rate for acute myeloid leukaemia patients remains low. Cytogenetic abnormalities and age are the prognostic factors that guide treatment decisions. However, many AML patients still die. The biological factors that influence treatment outcome are largely unknown. Thus, the objective of our study was to use the in vitro viability test to correlate with treatment outcome. Acute myeloid leukaemia blasts demonstrated differing ability to survive in culture. Our examination of blast phenotype at various days in culture showed two possible growth directions. First, cells underwent maturation by increased expression of CD16 and down-regulated CD34 (a haemopoietic stem cell marker). These cells also appeared to have undergone apoptosis. Alternatively, cells continued to survive in culture and maintained high expression of CD34. An MTT assay was carried out to determine viability after three days of culture. Lower optical density values were obtained for samples that underwent apoptosis and higher values were obtained for samples that survived in culture. Apoptosis was measured by Annexin V/propidium iodide staining. A comparison between results of MTT assay and duration of disease free survival revealed that a higher viability in vitro correlated significantly with shorter survival duration in the patient (R -0.761, p=0.002, n=13). Thus, this study further supports the hypothesis that AML patients with poor survival may be related to having blasts with a biologically more immature or stem cell-like nature.

    This study was undertaken to (a) determine wastewater treatment effectiveness using two freshwater organisms, (b) compare acute toxicity results from the two species exposed to the wastewaters, and (c) link acute and potential developmental toxicity of wastewaters in one organism. The acute toxicities of several pretreatment and post-treatment industrial waste-water samples wee evaluated with adult Hydra attenuata and fathead minnows. The acute LC50s agreed closely when results in Hydra attenuata were compared with those from fathead minnow tests. Acute LC50s ranged from 3 to >100% of samples with hydra, and from 1.0 to >100% of sample with fathead minnows. The results provided strong evidence of treatment effectiveness because toxicity decreased with progressive stages of treatment. Previously the Hydra Developmental Toxicity Assay was used as a prescreen mainly for in vitro assessment of developmental toxicity with pure compounds and to prioritized toxicants according to selective toxicity to the developing embryo. Recently the authors modified the assay for testing natural waters and wastewaters; hence, some of the wastewater samples also were tested for their developmental toxicity. In this case, the relative selective toxicity of these wastewater samples ranged from 0.7 to 2.1, indicating that no sample was uniquely toxic to the developing embryo, although acute toxicity was manifested. Overall, their results indicate the Hydra Assay functions appropriately in assessments of acute and developmental toxicity of industrial wastewaters and may be a simple and useful tool in a battery of tests for broader scale detection of environmental hazards.

    Wastewater tertiary treatment by advanced oxidation processes is thought to produce a treated effluent with lower toxicity than the initial influent. Here we performed tertiary treatment of a secondary effluent collected from a Waste Water Treatment Plant via homogeneous (solar/HSO5(-)/Fe(2+)) and heterogeneous (solar/TiO2) solar advanced oxidation aiming at the assessment of their effectiveness in terms of contaminants' and toxicity abatement in a plain solar reactor. A total of 53 organic contaminants were qualitatively identified by liquid chromatography coupled to high-resolution mass spectrometry after solid phase extraction. Solar advanced oxidation totally or partially removed the major part of contaminants detected within 4.5 h. Standard toxicity tests were performed using Vibrio fischeri, Daphnia magna, Pseudokirchneriella subcapitata and Brachionus calyciflorus organisms to evaluate acute and chronic toxicity in the secondary or tertiary effluents, and the EC50% was calculated. Estrogenic and genotoxic tests were carried out in an attempt to obtain an even sharper evaluation of potential hazardous effects due to micropollutants or their degradation by-products in wastewater. Genotoxic effects were not detected in effluent before or after treatment. However, we observed relevant estrogenic activity due to the high sensitivity of the HELN ERα cell line.

    Acute ankle injuries are among the most common injuries in emergency departments. However, there are still no standardized examination procedures or evidence-based treatment. Therefore, the aim of this study was to systematically search the current literature, classify the evidence, and develop an algorithm for the diagnosis and treatment of acute ankle injuries. We systematically searched PubMed and the Cochrane Database for randomized controlled trials, meta-analyses, systematic reviews or, if applicable, observational studies and classified them according to their level of evidence. According to the currently available literature, the following recommendations have been formulated: i) the Ottawa Ankle/Foot Rule should be applied in order to rule out fractures; ii) physical examination is sufficient for diagnosing injuries to the lateral ligament complex; iii) classification into stable and unstable injuries is applicable and of clinical importance; iv) the squeeze-, crossed leg- and external rotation test are indicative for injuries of the syndesmosis; v) magnetic resonance imaging is recommended to verify injuries of the syndesmosis; vi) stable ankle sprains have a good prognosis while for unstable ankle sprains, conservative treatment is at least as effective as operative treatment without the related possible complications; vii) early functional treatment leads to the fastest recovery and the least rate of reinjury; viii) supervised rehabilitation reduces residual symptoms and re-injuries. Taken these recommendations into account, we present an applicable and evidence-based, step by step, decision pathway for the diagnosis and treatment of acute ankle injuries, which can be implemented in any emergency department or doctor's practice. It provides quality assurance for the patient and promotes confidence in the attending physician. PMID:22577506

    Acute kidney injury (AKI) is increasingly recognized in all fields of medical practice. Unfortunately, this syndrome has been plagued by inconsistent definitions, simplistic pathophysiologic schemas, and insensitive diagnostic tools. Recent advances in defining AKI, understanding its pathophysiology, and improving the diagnostic accuracy of the testing tools available eventually will impact disease management and clinical outcomes. Prompt recognition and treatment of AKI remain the cornerstone of clinical management for this high-mortality, high-cost syndrome. The authors provide the most recent updates in the definition, diagnosis, pathophysiology, and treatment options for patients with AKI, providing a stepwise approach to clinical evaluation for use in all fields of medical practice.

    Therapeutic hypothermia is method used to improve the neurological status of patients who are at risk of ischaemia after myocardial infarction. We report a case of a 28-year-old woman who suffered acute myocardial infarction complicated by ventricular fibrillation. The patient was successfully resuscitated. Invasive and non-invasive medical treatment was applied including therapeutic hypothermia. Success was achieved due to adequate public reaction, fast transportation, blood vessel revascularization and application of therapeutic hypothermia. The patient was successfully discharged after one week of treatment, and just minor changes in heart function were present. PMID:24570755

    The present report describes the cases of a 17-year-old male patient and a 13-year-old female patient who developed acute dystonia following the administration of low-dose aripiprazole (5 mg/day) after the cessation of atomoxetine treatment. Although aripiprazole-induced dystonia has been previously reported in the literature, it is rare, and most of these cases were associated with doses higher than 5 mg/day. Furthermore, both of the patients in the present study discontinued atomoxetine prior to the initiation of aripiprazole treatment; thus, this report also discussed the possible mechanisms underlying the manifestation of dystonia from the perspective of neurotransmitter activity.

    There is no consensus about the best time to start exercise after peripheral nerve injury. We evaluated the morphological and functional characteristics of the sciatic nerves of rats that began to swim immediately after crush nerve injury (CS1), those that began to swim 14 days after injury (CS14), injured rats not submitted to swimming (C), and uninjured rats submitted to swimming (S). After 30 days the number of axons in CS1 and CS14 was lower than in C (P < 0.01). The diameter of axons and nerve fibers was larger in CS1 (P < 0.01) and CS14 (P < 0.05) than in C, and myelin sheath thickness was lower in all crushed groups (P < 0.05). There was no functional difference between CS1 and CS14 (P > 0.05). Swimming exercise applied during the acute or late phase of nerve injury accelerated nerve regeneration and synaptic elimination after axonotmesis, suggesting that exercise may be initiated immediately after injury.

    Seventeen burned patients were investigated--Group I (n=10) with a mean burned area expressed as unit burn standard (UBS) of 69 +/- 24 and Group II (n = 7) with a mean UBS of 23 +/- 8. Blood samples were collected immediately after admission, 6-12 h after injury, during the morning and evening of day 1, and then daily for 2 weeks. This prospective study demonstrated complement activation in vivo in all burned patients, measured by C3d/C3 ratio index which was not related to the extent of the burned surface. A significant protease-antiprotease imbalance, correlated to the severity of burns, was found, leukocyte elastase was increased throughout the observation period, alpha 2-macroglobulin drastically decreased in severely burned patients, and alpha 1-proteinase inhibitor promptly decreased below the normal level in patients with more than 40 UBS. Finally, there was a delayed but then persistent acute-phase reactant protein response involving C-reactive protein, haptoglobin and alpha 1-acid glycoprotein, the concentrations of which reached a plateau on days 6 or 7.

  12. NRF2 and the Phase II Response in Acute Stress Resistance Induced by Dietary Restriction

    2013-01-01

    Dietary restriction (DR) as a means to increase longevity is well-established in a number of model organisms from yeast to primates. DR also improves metabolic fitness and increases resistance to acute oxidative, carcinogenic and toxicological stressors - benefits with more immediate potential for clinical translation than increased lifespan. While the detailed mechanism of DR action remains unclear, a conceptual framework involving an adaptive, or hormetic response to the stress of nutrient/energy deprivation has been proposed. A key prediction of the hormesis hypothesis of DR is that beneficial adaptations occur in response to an increase in reactive oxygen/nitrogen species (ROS). These ROS may be derived either from increased mitochondrial respiration or increased xenobiotic metabolism in the case of some DR mimetics. This review will focus on the potential role of the redox-sensing transcription factor NF-E2-related factor 2 (NRF2) and its control of the evolutionarily conserved antioxidant/redox cycling and detoxification systems, collectively known as the Phase II response, in the adaptive response to DR.

    We have previously shown that peripherally restricted acute phase response (APR) elicited by intraperitoneal (i.p.) injection of a viral mimic, polyinosinic-polycytidylic acid (PIC), renders the brain hypersusceptible to excitotoxic insult as seen from profoundly exacerbated kainic acid (KA)-induced seizures. In the present study, we found that this hypersusceptibility was protracted for up to 72 h. RT-PCR profiling of hippocampal gene expression revealed rapid upregulation of 23 genes encoding cytokines, chemokines and chemokine receptors generally within 6 h after PIC challenge. The expression of most of these genes decreased by 24 h. However, two chemokine genes, i.e., Ccl19 and Cxcl13 genes, as well as two chemokine receptor genes, Ccr1 and Ccr7, remained upregulated for 72 h suggesting their possible involvement in the induction and sustenance of seizure hypersusceptibility. Also, 12 genes encoding proteins related to glutamatergic and GABAergic neurotransmission featured initial upregulation or downregulation followed by gradual normalization. The upregulation of the Gabrr3 gene remained upregulated at 72 h, congruent with its plausible role in the hypersusceptible phenotype. Moreover, the expression of ten microRNAs (miRs) was rapidly affected by PIC challenge, but their levels generally exhibited oscillating profiles over the time course of seizure hypersusceptibility. These results indicate that protracted seizure susceptibility following peripheral APR is associated with a robust polygenic response in the hippocampus. PMID:24363211

    The distinction between exudates and transudates is very important in the patient management. Here we evaluate whether the acute-phase protein serum amyloid A (SAA), in comparison with C reactive protein (CRP) and total protein (TP), can be useful in this discrimination. CRP, SAA, and TP were determined in 36 exudate samples (27 pleural and 9 ascitic) and in 12 transudates (9 pleural and 3 ascitic). CRP, SAA, and TP were measured. SAA present in the exudate corresponded to 10% of the amount found in serum, that is, the exudate/serum ratio (E/S) was 0.10 ± 0.13. For comparison, the exudate/serum ratio for CRP and TP was 0.39 ± 0.37 and 0.68 ± 0.15, respectively. There was a strong positive correlation between serum and exudate SAA concentration (r = 0.764;p < 0.0001). The concentration of SAA in transudates was low and did not overlap with that found in exudates (0.02-0.21 versus 0.8–360.5 g/mL). SAA in pleural and ascitic exudates results mainly from leakage of the serum protein via the inflamed membrane. A comparison of the E/S ratio of SAA and CRP points SAA as a very good marker in discriminating between exudates and transudates. PMID:16864904

    The aim of this study was to investigate the effects of transport-related stress on the liver gene expression of four acute phase proteins (APP), namely α1-acid glycoprotein (AGP), C-Reactive Protein (CRP), Serum Amyloid A (SAA) and PIT54, in turkeys (Meleagris gallopavo). A group of seven BUT BIG 6 commercial hens was subjected to a two-hour long road transportation and the quantitative gene expression of APP in the liver was compared to that of a non transported control group. The expression of AGP and CRP mRNA was found to be increased in animals slaughtered after road transport. The presence of AGP protein was also confirmed by immunohistochemistry and Western blotting. The results of this study showed that road-transport may induce the mRNA expression of immune related proteins. The finding that AGP and CRP can be upregulated during transport could suggest their use as for the assessment of turkey welfare during transport.

    Transport proteins, acute-phase reactant proteins (APRP), hematology, and anthropometry were studied in 34 sickle cell disease (SCD) children (20 boys, 14 girls) and 27 controls without growth deficits (13 boys, 14 girls) [corrected]. The age range was 1/2 to 16 1/2 years. Weight deficits (< 80%) by Waterlow's classification were observed in 41% of SCD boys and 25% of SCD girls, and height deficits (< 90%) were observed in 25% SCD boys and 25% girls. Mean white blood cell counts were significantly higher (P < .001) and hematocrit and hemoglobin (Hb) lower (P < .005) in SCD children than in controls. Although both groups had similar mean levels of albumin, transferrin, and APRP, SCD children had significantly lower mean levels of retinol-binding protein (RBP) (P < .001) and retinol-prealbumin (P < .001). Retinol-binding protein levels were abnormal in 18 (53%) SCD children and in only 23% controls (chi 2 = 14.06; P < 0.005); transferrin levels were abnormal in 20% of SCD children and in none of the controls. Children with SC and SF Hb phenotype had normal mean levels of RBP, whereas those with S beta thal and SS phenotype had levels below normal. Growth-retarded children by weight and height had reduced mean levels of RBP and prealbumin compared with growth-normal SCD children. The implication of primary protein-energy malnutrition on growth retardation in SCD children is under study. PMID:7512147

    Chronic viral hepatitis B (CHB) is an important cause of morbidity and mortality. Adipokine stimulation might play an important role in the pathogenesis of chronic inflammation. The aim of this study was to evaluate serum visfatin concentrations and the relationship between visfatin, fibrosis, liver inflammation, and acute phase reactants in CHB patients.The sampling universe of the study consisted of 41 CHB patients and 25 healthy controls. All patients had positive hepatitis B surface antigen (Hepatitis e antigen (HBeAg) positive n: 7, n: 34 HBeAg negative) for at least 6 months and detectable serum HBV DNA. Serum visfatin concentrations were significantly higher in the CHB patients [18.0 ± 10.9 ng dL(-1)] than in the healthy controls [9.4 ± 1.6 ng dL(-1)] [P < 0.001]. On the other hand, fibrinogen and haptoglobin concentrations were significantly lower in CHB patients. A strong negative correlation was observed between serum visfatin concentration, haptoglobin, and fibrinogen levels; however, there was no significant correlation between visfatin, glucose, alanine aminotransferase, aspartate aminotransferase, BMI, Knodell score, fibrosis score, hepatitis B virus DNA, sedimentation, and C-reactive protein. Visfatin concentrations were elevated and visfatin was negatively correlated with haptoglobin and fibrinogen levels in CHB patients.

    Older patients with acute myeloid leukemia (AML) have worse rates of complete remission and shorter overall survival than younger patients. The epigenetic modifier CC-486 is an oral formulation of azacitidine with promising clinical activity in patients with AML in Phase I studies. The Phase III, randomized, double-blind, placebo-controlled QUAZAR AML Maintenance trial (CC-486-AML-001) examines CC-486 maintenance therapy (300 mg/day for 14 days of 28-day treatment cycles) for patients aged ≥55 years with AML in first complete remission. The primary end point is overall survival. Secondary end points include relapse-free survival, safety, health-related quality of life and healthcare resource utilization. This trial will investigate whether CC-486 maintenance can prolong remission and improve survival for older patients with AML.

    Purpose: To report on early results of a single-institution phase 2 trial of a 5-fraction, once-weekly radiation therapy regimen for patients undergoing breast-conserving surgery (BCS). Methods and Materials: Patients who underwent BCS for American Joint Committee on Cancer stage 0, I, or II breast cancer with negative surgical margins were eligible to receive whole breast radiation therapy to a dose of 30 Gy in 5 weekly fractions of 6 Gy with or without an additional boost. Elective nodal irradiation was not permitted. There were no restrictions on breast size or the use of cytotoxic chemotherapy for otherwise eligible patients. Patients were assessed at baseline, treatment completion, and at first posttreatment follow-up to assess acute toxicity (Common Terminology Criteria for Adverse Events, version 3.0) and quality of life (European Organization for Research and Treatment of Cancer QLQ-BR23). Results: Between January and September 2011, 42 eligible patients underwent weekly hypofractionated breast irradiation immediately following BCS (69.0%) or at the conclusion of cytotoxic chemotherapy (31.0%). The rates of grade ≥2 radiation-induced dermatitis, pain, fatigue, and breast edema were 19.0%, 11.9%, 9.5%, and 2.4%, respectively. Only 1 grade 3 toxicity—pain requiring a course of narcotic analgesics—was observed. One patient developed a superficial cellulitis (grade 2), which resolved with the use of oral antibiotics. Patient-reported moderate-to-major breast symptoms (pain, swelling, and skin problems), all decreased from baseline through 1 month, whereas breast sensitivity remained stable over the study period. Conclusions: The tolerance of weekly hypofractionated breast irradiation compares well with recent reports of daily hypofractionated whole-breast irradiation schedules. The regimen appears feasible and cost-effective. Additional follow-up with continued accrual is needed to assess late toxicity, cosmesis, and disease-specific outcomes.
