    Full Text Available Acute acalculous cholecystitis is a rare complication in the treatment of acute myeloblastic leukemia. Diagnosis of acute acalculous cholecystitis remains difficult during neutropenic period. We present two acute myeloblastic leukemia patients that developed acute acalculous cholecystitis during chemotherapy-induced neutropenia. They suffered from fever, vomiting and acute pain in the epigastrium. Ultrasound demonstrated an acalculous gallbladder. Surgical management was required in one patient and conservative treatment was attempted in the other patient. None treatment measures were effective and two patients died. Acute acalculous cholecystitis is a serious complication in neutropenic patients. Earlier diagnosis could have expedited the management of these patients.

    Reduced visual acuity in patients with acute leucemia can result from many causes including an ocular localization. A patient previously treated for acute myeloblastic leucemia-5 (AML5) developed bilateral vision impairment related to a subretinal localization of the leucemia. Meningeal and bone marrow relapse followed. The subretinal localization responded only to massive systemic steroid treatment. Although asymptomatic, ocular localizations are frequent in leucemia. Their prognostic impact depends on the ocular structure involved and on the chronology of onset--early or late in the leucemia course. The underlying pathophysiological mechanism of ocular involvement remains unexplained but hyperleucocytosis at presentation may be a risk factor and would justify at least systematic specialized examinations and discussion of prophylactic treatment.

    Immunity against acute myeloid leukemia (AML) is demonstrated in humans by the graft-versus-leukemia effect in allogeneic hematopoietic stem cell transplantation. Specific leukemic antigens have progressively been discovered and circulating specific T lymphocytes against Wilms tumor antigen, proteinase peptide or fusion-proteins produced from aberrant oncogenic chromosomal translocations have been detected in leukemic patients. However, due to the fact that leukemic blasts develop various escape mechanisms, antileukemic specific immunity is not able to control leukemic cell proliferation. The aim of immunotherapy is to overcome tolerance and boost immunity to elicit an efficient immune response against leukemia. We review different immunotherapy strategies tested in preclinical animal models of AML and the human trials that spurred from encouraging results obtained in animal models, demonstrate the feasibility of immunotherapy in AML patients.

    The assessment of minimal residual disease (MRD) in acute myeloblastic leukemia is of growing interest as a prognostic marker of patients' outcome. Multiparameter flow cytometry (MFC), tracking leukemia-associated immunophenotypic patterns, has been shown in several studies to be a useful tool to investigate MRD. Here, we report a multicenter prospective study which allowed to define a harmonized analysis strategy, as well as the efficacy of MFC MRD to predict outcome. This study included 276 patients, in 10 different MFC centers, of whom 268 had at least 1 MRD check point. The combination of a CD45, CD34, and CD33 backbone, with the addition of CD117, CD13, CD7, and CD15 in 2 five-color tubes allowed to define each patient's multiparameter immunophenotypic characteristics at diagnosis, according to a Boolean combination of gates. The same individual diagnosis gating strategy was then applied at each MRD time point for each patient. MRD levels were stratified according to log by log thresholds, from 5 × 10 -2 (the classical morphological threshold to define remission) down to MRD1) as well as when considering all time points together. Finally, MRD levels were independent of cytogenetics and allowed in fact to further stratify all cytogenetics risk groups. In summary, this multicenter study demonstrates that a simple combination of immunophenotypic markers successfully allows for the detection of MRD in acute myeloblastic leukemia patients, with a strong correlation to outcome.

    Thrombocytosis is commonly seen in reactive conditions and certain neoplastic states, such as chronic myeloproliferative disorders. It is rarely seen in acute leukemia. A 12-year-old girl with acute myeloblastic leukemia (FAB M2) in remission presented with pyoderma. Her hemogram revealed anemia (Hb-6.4g/dl), leucopenia (TLC - 1.2 x 109/L) and thrombocytosis (platelet count- 580 x 109/L). A peripheral blood film showed numerous abnormally large platelets with few atypical cells. The thrombocytosis subsided with the clearance of infection but atypical cells persisted. One month later, she relapsed. Cytogenetic analysis revealed variable results (trisomy 9 and deletion 3). This case has been presented because thrombocytosis is rare in AML and its appearance calls for a close follow-up.

    Granulocyte/macrophage-colony-stimulating factor (GM-CSF) is an effective growth factor for the blasts of acute myeloblastic leukemia (AML). Radioiodinated Chinese hamster ovary (CHO)-cell derived GM-CSF was prepared using Bolton-Hunter reagent to label free amino groups on the protein. Normal human neutrophils and the blast cells from AML patients were examined for binding. We found that there were fewer receptors of higher affinity on blast cells compared with neutrophils. After brief culture in suspension, receptor number increased and affinity decreased. Experiments provided evidence that GM-CSF from Escherichia coli had a higher affinity for neutrophils (kd = 20 pM) than the CHO-cell derived protein (kd = 500 pM-1 nM). This difference was reflected in the increased effectiveness of the E. coli protein over the CHO protein to stimulate colony formation in both normal bone marrow cells and AML blasts

    Full Text Available Abstract Background The presence of MLL rearrangements in acute leukemia results in a complex number of biological modifications that still remain largely unexplained. Armstrong et al. proposed MLL rearrangement positive ALL as a distinct subgroup, separated from acute lymphoblastic (ALL and myeloblastic leukemia (AML, with a specific gene expression profile. Here we show that MLL, from both ALL and AML origin, share a signature identified by a small set of genes suggesting a common genetic disregulation that could be at the basis of mixed lineage leukemia in both phenotypes. Methods Using Affymetrix® HG-U133 Plus 2.0 platform, gene expression data from 140 (training set + 78 (test set ALL and AML patients with (24+13 and without (116+65 MLL rearrangements have been investigated performing class comparison (SAM and class prediction (PAM analyses. Results We identified a MLL translocation-specific (379 probes signature and a phenotype-specific (622 probes signature which have been tested using unsupervised methods. A final subset of 14 genes grants the characterization of acute leukemia patients with and without MLL rearrangements. Conclusion Our study demonstrated that a small subset of genes identifies MLL-specific rearrangements and clearly separates acute leukemia samples according to lineage origin. The subset included well-known genes and newly discovered markers that identified ALL and AML subgroups, with and without MLL rearrangements.

    Survival for patients with acute myeloblastic leukemia (AML) has increased during the past two decades. However, socioeconomic disparities may affect survival for some patient populations. We examine survival by insurance type for patients with AML. Using data from the Surveillance, Epidemiology, and End Results database we estimated survival according to insurance status (no insurance, Medicaid, and other insurance) for patients diagnosed with AML in the United States in 2007-2013. One, 3-, and 5-year survival was lower for patients with no insurance and Medicaid than for patients with other insurance. Five-year survival estimates were 24.7%, 25.6%, and 35.7%, respectively, for patients with Medicaid, no insurance, and other insurance. After adjustment, hazard ratios of 1.46 for uninsured and 1.35 for Medicaid compared to other insurance for overall survival and 1.50 for uninsured and 1.30 for Medicaid compared to other insurance for AML-specific survival were observed. Similar results were seen in all ages and both genders. Patients with no insurance or Medicaid have lower survival expectations after diagnosis with AML than patients with other insurance. Further research into reasons for the poor outcomes for Medicaid patients and continued reduction of number of uninsured people are urgently needed to improve population-level outcomes for AML.

    Full Text Available We present herein a 23-year-old man with acute myeloblastic leukemia (AML associated with Davidoff-Dyke-Masson syndrome (DDMS and Marfan syndrome (MS. The diagnosis of DDMS was based on findings including left facial asymmetry, left hemiparesis, mental retardation, right cerebral hemiatrophy, dilatation of the ipsilateral lateral ventricle and calvarial thickening. The diagnosis of MS was based on clinical findings including tall stature, myopia, retinitis pigmentosa, blue scleras, scoliosis, pectus excavatum, arachnodactyly and low ratio of upper/lower body segment. The patient developed hepatosplenomegaly, gingival hypertrophy and pancytopenia. Peripheral blood film and bone marrow examination showed that most of nucleated cells were blasts; immunophenotype of those cells showed CD11+, CD13+, CD14+, CD33+ and HLA-DR+. These findings confirmed the diagnosis of AML (FAB-M5. After induction chemotherapy, remission was obtained. To the best of our knowledge, our case is the third report of AML in MS syndrome, while AML associated with DDMS and MS has not been previously reported in the literature.

    Central pontine myelinolysis (CPM) is a demyelinating disease of the pons often associated with the demyelination of extrapontine areas of the central nervous system. It typically occurs 0.5-7 days after a rapid increment in serum Na level in hyponatremic patients and may lead to death. A 2.5-year-old child with a diagnosis of acute myeloblastic leukemia developed febril neutropenia, diarrhea, gastrointestinal hemorrhage followed by pulmonary aspergillosis. He could not tolerate enteral nutrition. He was given broad spectrum antibiotics and antifungal treatment. Laboratory tests showed electrolyte abnormalities including hyponatremia, hypokalemia and hypophosphatemia in a chronic course. Twenty three days after a rapid correction of hyponatremia (16 mEq/L/24 h) he revealed flask quadriparesis, disphagia, mutism, irregular respiratory pattern and loss of cough and gag reflex. Cranial magnetic resonance showed central pontine and extrapontine myelinolysis. He required mechanical ventilation and then he regained his neurologic functions. He completed chemotherapy protocol and underwent hematopoietic stem cell transplantation. After 2.5 years of the occurrence of CPM he is in completely normal physical and neurological status. CPM is a very severe but rare disorder in children with underlying disease. In the presence of multiple etiologic factors it may reveal a delayed onset and optimum outcome can be seen even in the severe clinical presentation with adequate intensive support.

    The blast cells in acute myeloblastic leukemia (AML) respond to many of the same regulatory mechanisms that control normal hemopoiesis. These include the growth factors that bind to membrane receptors and steroid hormones or vitamins that have intracellular receptors. The authors report the effects in culture of the steroid glucocorticoid hydrocortisone on freshly explanted AML blasts from patients and on two continuous AML cell lines. Only small changes in clonogenic cell numbers in suspension cultures were seen in the presence of hydrocortisone. The most striking effect of the hormone was on the sensitivity of blasts cells to cytosine arabinoside (ara-C). In contrast to the response of AML blast cells to retinoic acid, a ligand for intracellular steroid receptors that sensitizes some blast populations to ara-C, hydrocortisone reduced the toxic effects of the drug. The protective action of hydrocortisone was not mediated through the cell cycle since exposure of blasts to hydrocortisone did not affect the percentage of cells in DNA synthesis as measured with the tritiated thymidine (3HTdR) suicide technique. The hydrocortisone effect could be demonstrated using a pulse (20 min) exposure protocol. Blasts pulsed with increasing specific activities of 3HTdR showed the usual response pattern with an initial loss in plating efficiency to about 50% of control, followed by a plateau, regardless of whether the cells had been exposed to hydrocortisone. Control blasts exposed to increasing ara-C concentrations gave very similar dose-response curves; in striking contrast, blast cells cultured in hydrocortisone, then pulsed with ara-C did not lose colony-forming ability even though the same population was sensitive to 3HTdR.

In this study, we examined the effects and mechanism of action of lapatinib on several human leukemia cells lines, including acute myeloid leukemia (AML, chronic myeloid leukemia (CML, and acute lymphoblastic leukemia (ALL cells. We found that lapatinib inhibited the growth of human AML U937, HL-60, NB4, CML KU812, MEG-01, and ALL Jurkat T cells. Among these leukemia cell lines, lapatinib induced apoptosis in HL-60, NB4, and Jurkat cells, but induced nonapoptotic cell death in U937, K562, and MEG-01 cells. Moreover, lapatinib treatment caused autophagic cell death as shown by positive acridine orange staining, the massive formation of vacuoles as seen by electronic microscopy, and the upregulation of LC3-II, ATG5, and ATG7 in AML U937 cells. Furthermore, autophagy inhibitor 3-methyladenine and knockdown of ATG5, ATG7, and Beclin-1 using short hairpin RNA (shRNA partially rescued lapatinib-induced cell death. In addition, the induction of phagocytosis and ROS production as well as the upregulation of surface markers CD14 and CD68 was detected in lapatinib-treated U937 cells, suggesting the induction of

Forty three patients with AML and 52 normal controls were enrolled in this study in the Department of Hematology, Tumor Center of Qilu Hospital of Shandong University from Feb. 2008 to Mar.2009. Serum lgG and lgM antibodies versus the oxLDL levels were evaluated by ELISA method. Data was analyzed by covariance and binary Logistic regression. Serum mean levels of oxLDL-lgG in patients (38.92 +/- 21.1259 ug/ml) were significantly lower than in control subjects (78.88 +/- 9.3705 ug/ml); Meanwhile, Serum mean levels of oxLDL-lgM in patients (20.53 +/- 10.2990 IU/L) were significantly higher than in control subjects (10.29 +/- 10.5771 IU/L). Binary logistic regression showed the odds ratios of association of oxLD-lgG and oxLD-lgM with adult AML were 0.72(95%CI: 0.55-0.94) and 1.11(95%CI: 1.01-1.21) respectively after adjusted for potential confounders. In the preliminary investigation we found a descensive oxLDL- lgG and an elevated oxLDL-lgM serum levels for the adult AML. Future studies need to confirm the hypothesis whether they related to the development and progression of adult AML.

    Childhood acute myeloid leukemia (AML) achieves event-free-survival (EFS) rates of ∼50%. Double induction phase has been introduced for improving these results. Four consecutive protocols for AML treatment were evaluated to assess the impact of the addition of a second induction course in our setting. From January 1990 to January 2014, 307 evaluable AML patients were accrued. They were classified into low-risk (LR) and high-risk (HR) according to cytogenetic/molecular findings and response on day 15. The first two studies administered one induction cycle while the latter two protocols administered double induction. Relapse was the most frequent event and early-deaths were reduced by 50% in the last protocol. Statistically significant differences were observed when comparing EFS in LR and HR groups. Patients from both risk-groups who received double induction achieved significantly better outcome. EFS improved in protocols with double induction and early-deaths rate was decreased. Cytogenetic/molecular features and early-response were confirmed as prognostic factors.

  1. Quantitative assessment of Wilms tumor 1 expression by real-time quantitative polymerase chain reaction in patients with acute myeloblastic leukemia

    2017-01-01

    Full Text Available Background: The Wilms tumor 1 (WT1 gene is originally defined as a tumor suppressor gene and a transcription factor that overexpressed in leukemic cells. It is highly expressed in more than 80% of acute myeloid leukemia (AML patients, both in bone marrow (BM and in peripheral blood (PB, and it is used as a powerful and independent marker of minimal residual disease (MRD; we have determined the expression levels of the WT1 by real-time quantitative polymerase chain reaction (RQ-PCR in PB and BM in 126 newly diagnosed AML patients. Materials and Methods: This study was done in molecular pathology and cancer research center from April 2014 to June 2015, RQ-PCR method was used to determine the WT1 gene expression in BM and/or PB samples from 126 patients of AML, we cloned both WT1 and ABL genes for creating a standard curve, and we calculate copy number of WT1 genes in patients. Results: A total of 126 AML patients consist of 70 males (55.6% and 56 females (44.4%, with a median age of 26 years; 104 (81% patients out of 126 show overexpression of WT1 gene. We also concomitant monitoring of fusion transcripts (PML RARa, AML1-ETO, MLL-MLL, CBFb-MYH11, or DEK-CAN in our patients, the AML1-ETO group showing remarkably low levels of WT1 compared with other fusion transcript and the CBFB-MYH11 showing high levels of WT1. Conclusion: We conclude that WT1 expression by RQ-PCR in AML patients may be employed as an independent tool to detect MRD in the majority of normal karyotype AML patients.

    Results of reduced intensity conditioning regimen (RIC) in the HLA identical haematopoietic stem cell transplantation (HSCT) setting have not been compared to those after myeloablative (MA) regimen HSCT in patients with acute myeloblastic leukaemia (AML) over 50 years of age. With this aim, outcomes of 315 RIC were compared with 407 MA HSCT recipients. The majority of RIC was fludarabine-based regimen associated to busulphan (BU) (53%) or low-dose total body irradiation (24%). Multivariate analyses of outcomes were used adjusting for differences between both groups. The median follow-up was 13 months. Cytogenetics, FAB classification, WBC count at diagnosis and status of the disease at transplant were not statistically different between the two groups. However, RIC patients were older, transplanted more recently, and more frequently with peripheral blood allogeneic stem cells as compared to MA recipients. In multivariate analysis, acute GVHD (II-IV) and transplant-related mortality were significantly decreased (P=0.01 and P<10(-4), respectively) and relapse incidence was significantly higher (P=0.003) after RIC transplantation. Leukaemia-free survival was not statistically different between the two groups. These results may set the grounds for prospective trials comparing RIC with other strategies of treatment in elderly AML.

    1. Myeloblasts can be discriminated in the supravital technique by the great numbers of tiny mitochondria in the cytoplasm and the absence of any other vitally stainable substance. 2. There are three stages in the maturation of myelocytes. 3. These three phases can be correlated with three types of the oxidase reaction. 4. One case of myeloblastic leucemia showed such an amount of an abnormal type of amitosis as to suggest the disordered cell division of neoplasms. 5. In this case transfusions were correlated with a maturation of myeloblasts into myelocytes, with an increase of the oxidase reaction, and with an increase in amitosis.

    Pseudo-Chediak-Highashi granules are giant cytoplasmic inclusions commonly encountered in myeloblasts or other myeloid precursors in acute myeloid leukemia and myelodysplastic syndromes. They derive their name from the inherited Chediak-Higashi syndrome that presents with oculocutaneous albinism, chronic infections and platelet dense granule deficiency. We report possibly the third case in world literature where these granules were seen in the blast cells of acute lymphoblastic leukemia in a 15-year-old male.

    Full Text Available Acute erythroid leukemia (AEL is a rare subtype of acute myeloid leukemia(AML, characterized by predominant erythroid proliferation. The 2008 WorldHealth Organization (WHO classification of AML defined two AEL subtypes:erythroleukaemia (EL, in which erythroid precursors account for 50% or moreof all nucleated bone marrow cells and myeloblasts account for 20% or more ofthe nonerythroid cell population; and pure erythroid leukemia (PEL, in whicherythroid precursors account for 80% or more of all nucleated bone marrowcells. We report the case of an elderly female patient with wasting syndromeand pancytopenia without evidence of blasts in peripheral blood. A diagnosisof PEL was established on the basis of bone marrow biopsy findings. Thepatient died on postadmission day 20, and an autopsy was performed. Wereclassified the disease as EL on the basis of the autopsy findings, whichincluded myeloblasts accounting for more than 20% of the nonerythroid cellsin the bone marrow, as well as leukemic infiltration and myeloid metaplasia insolid organs, such as the liver, spleen, kidneys, adrenal glands, and abdominallymph nodes. A rare disease, AEL accounts for less than 5% of all AMLs and ispractically a diagnosis of exclusion. Autopsy reports of AEL are extremely rarein the literature. We demonstrate that in the case reported here, leukemia cellstended to infiltrate solid organs with myeloid metaplasia. Our findings alsoshow that a larger neoplastic bone marrow sample is crucial to the correctdiagnosis of EL, which is based on morphological and quantitative criteria.

    Pleural effusions can be the first presentation of a hematologic malignancy. The most common disorders with pleural effusion are Hodgkin and non-Hodgkin lymphoma with a frequency of 20 to 30%, especially if mediastinal involvement. Acute and chronic leukemia are rarely accompanied by pleural involvement. We describe a 46-year-old female with history of progressive dyspnoea. Physical examination was revealed massive left pleural effusion. Complete blood count revealed anemia, trombositopenia and normal leucocyte count. Viral serology test shown positive of HBsAg and total antiHBc. Chest X-ray revealed left pleural effusion. Pleural fluid cytology was myeloblast consistent with acute myeloid leukemia (AML). Bone marrow aspiration smear, bone marrow biopsy smear, and flow cytometry analysis were consistent with acute myeloid leukemia without maturation (AML M0-FAB classification).

    Acute myeloid leukemia is an aggressive myeloid neoplasm characterized by ≥20% myeloblasts in the blood or bone marrow. Current treatment strategies for acute myeloid leukemia are based on both patient-related parameters such as age and performance status as well as the intrinsic characteristics of particular disease subtypes. Subtyping of acute myeloid leukemia requires an integration of information from the patient's clinical history (such as any prior preleukemic myeloid neoplasm or cytotoxic potentially leukemogenic therapy), the leukemia morphology, cytogenetic findings, and the mutation status of particular genes (NPM1, FLT3, and CEBPA). In recent years, a barrage of information has become available regarding gene mutations that occur in acute myeloid leukemia and their influence on prognosis. Future therapies for acute myeloid leukemia will increasingly rely on the genetic signatures of individual leukemias and will adjust therapy to the predicted disease aggressiveness as well as employ therapies targeted against particular deregulated genetic pathways. This article reviews current standards for diagnosing and classifying acute myeloid leukemia according to the 2008 WHO Classification. Data that have subsequently accumulated regarding newly characterized gene mutations are also presented. It is anticipated that future leukemia classifications will employ a combination of karyotypic features and the gene mutation pattern to stratify patients to increasingly tailored treatment plans. © 2013 Blackwell Publishing Ltd.

Because most patients will have chemotherapy-resistant disease, allogeneic hematopoietic stem cell transplantation remains the only potentially curative treatment. Despite advances in current management, patients continue to have poor outcomes and lack of durable responses. Thus, new therapies with alternative modes of actions are currently being investigated. Blinatumomab is a novel bispecific T-cell engager that simultaneously binds CD3-positive cytotoxic T-cells and CD19-positive B-cells, resulting in selective lysis of tumor cells. It has shown promising results in patients with relapsed or refractory acute lymphoblastic leukemia or those achieving hematologic response with persistent minimum residual disease. Future clinical trials will answer questions regarding its optimal place in the treatment paradigm. Dose-limiting toxicities include immunological toxicities and cytokine release syndrome. However, most patients tolerate the therapy relatively well. This review will focus on the pharmacology, clinical efficacy, and safety of blinatumomab in the treatment of adult B-cell acute lymphoblastic leukemia while highlighting its unique drug

    Full Text Available Background Leptin is a multifunctional hormone plays an important role in regulating lipid, energy, homeostasis, angiogenesis, inflammation, hematopoiesis and cell cycle. This polypeptide is effective in growth and differentiation of leukemic cells through an Ob-R receptor expressed by them. Objectives The purpose of this study was to evaluate serum leptin levels in patients with acute leukemia and compare it in lymphoid and myeloid groups. Patients and Methods This analytical case-control study, conducted on 60 children in age ranged from 6 months to 16 years in two case and control groups in Ali ibn Abi Talib hospital, Zahedan. They matched based on age and gender and examined after their parent’s satisfaction according to the parental consent forms. None of patients had heart disease, digestive, glandular and metabolic problems, iron deficiency anemia and chronic kidney disease. After collecting the samples, leptin levels of both groups were measured with ELISA kit. Then, the gathered data were analyzed in SPSS-20 software, using independent t-test in considering of 95% confidence interval. Results Leptin serum levels in patients with acute leukemia and controls showed significant difference (P < 0.05. Leptin serum levels in patients with acute lymphoblastic leukemia and acute myeloblastic leukemia showed significant difference (P < 0.05. Leptin serum level in relation to age and gender groups was not statistically significant. Conclusions The findings of this study showed that in patients with acute leukemia, leptin serum levels increase independently of age and gender. In addition, leptin serum levels in acute lymphoid leukemia were higher than acute myeloid leukemia in this study.

    Blinatumomab, a bi-specific T-cell engaging CD3-CD19 antibody construct, has shown significant activity in patients with relapsed/refractory (R/R) B-cell acute lymphoblastic leukemia (ALL). Despite this improvement, most patients relapse. Here, we describe the outcome of 68 patients with R/R ALL after failure of blinatumomab therapy: 38 (56%) blinatumomab refractory; 30 (44%) relapsing after initial response. After a median follow-up of 49 months, 9 (13%) patients remained alive. The median overall survival after blinatumomab failure was 5.2 months. At the time of failure, among 61 patients evaluated for immunophenotype, 56 (92%) had CD19-positive blasts; only five (8%) had ALL recurrence with CD19-negative disease. Two patients progressed with lower CD19 expression. In summary, the outcome of patients with R/R ALL after blinatumomab failure is poor and treatment of these patients remains an unmet medical need. Our findings indicate that blinatumomab therapy would not exclude a significant number of patients from the potential benefit of subsequent CD19-directed therapies such as chimeric antigen receptor T-cell therapy. © 2017 Wiley Periodicals, Inc.

    Acute myeloid leukemia is an acquired clonal heterogeneous stem cell disorder. Hence, various parameters are sought out to categorize this disease into subtypes, so that as a consequence specific treatment modalities can be offered. Conventionally, the practically used method for classification utilizes French American British (FAB) criteria based on morphology and cytochemistry. The aim of present study was to determine the current spectrum of AML sub types in patients in Karachi. This single centre cross sectional study was conducted at Liaquat National Hospital, Karachi, extending from January 2010 to December 2014. Data were retrieved from archives were analyzed with SPSS version 22. A total of 125 patients were diagnosed at our institution with de novo AML during five years period, 76 males and 49 females. Median age was 34.5 years. AML-M1 was the predominant FAB subtype (23.2%) followed by M2 (18.4%), M3 and M4 (16% each), M0 (14.4%), M5 (7.2%), M6 (3.2%) and M7 (1.6%). AML in Pakistani patients is seen in a relatively young population. The most common FAB subtype observed in our study was acute myeloblastic leukemia, without maturation (M1).

    A 22-year-old female was diagnosed as having acute lymphoid leukemia (ALL) in February 1995, from the findings of peroxidase negative, CD10+, CD19+, TdT+ and rearrangement of IgH and TCR beta. AdVP (doxorubicin, vincristine and prednisolone) therapy achieved a complete remission (CR). Bone marrow transplantation had to be abandoned because of the lack of an HLA-identical donor. Intensification therapy was thus carried out repeatedly. In June 1998, myeloblast with Auer rods, peroxidase positive, CD13+, CD33+ and HLA-DR+, appeared. The patient was diagnosed as having lineage switch acute myeloid leukemia (AML) from ALL. Though A-DMP (cytosine arabinoside, daunorubicin, 6-mercaptopurine) therapy was resistant, AdVP therapy led to a CR. The patient died of cardiotoxicity from anthracyclines in February 1999. From the results of the Ramasamy method using the clonal rearrangements of the Ig heavy chain gene locus, the origin of the pathological cells of ALL and AML was indicated to be the same leukemia clone.

    Full Text Available Manon Queudeville, Rupert Handgretinger, Martin Ebinger Department of Pediatric Hematology and Oncology, University Children’s Hospital, University of Tübingen, Tübingen, Germany Abstract: Patients with refractory or relapsed (R/R acute lymphoblastic leukemia (ALL have a dismal prognosis of around 5% long-term survival when treated with cytotoxic chemotherapy and allogenic stem cell transplantation. T-cell immunobased strategies open up new therapeutic perspectives. Blinatumomab is the first of a new class of antibody constructs that was labeled bispecific T-cell engager (BiTE: it consists of two single chain variable fragment connected with a flexible linker, one side binding CD3, the other CD19. The tight binding and the close proximity to the CD19-positive B-cells and leukemic cells leads to non-major histocompatibility complex-restricted T-cell activation, polyclonal T-cell expansion and direct target cell killing. Applied by continuous infusion, blinatumomab achieves morphological complete response rates ranging from 39% to 69% in R/R ALL patients (compared to 25% after second-line chemotherapy with prolonged overall survival (blinatumomab median overall survival, 7.7 months vs chemotherapy, 4.0 months. In comparison to conventional cytotoxic second-line protocols blinatumomab has a favorable safety profile. The main adverse event is related to the mode of action of blinatumomab: the induction of a cytokine-release syndrome that can be managed by interruption and/or the application of steroids or tocilizumab. Another typical complication is the occurrence of neurological side effects, such as seizures and encephalopathy. This neurotoxicity is reversible after application of steroids and/or withdrawal of blinatumomab. Blinatumomab has proven to be a powerful therapeutic option in R/R ALL patients both adult and pediatric because of its efficacy and limited toxicity.

    We conducted a retrospective study of patients with cutaneous myeloid sarcoma, from 2 tertiary care institutions. Eighty-three patients presented, with a mean age of 52 years. Diagnosis of myeloid sarcoma in the skin was difficult due to the low frequency of myeloperoxidase and/or CD34+ cases (56% and 19% of tested cases, respectively). Seventy-one of the 83 patients (86%) had ≥ 1 bone marrow biopsy. Twenty-eight (39%) had acute myeloid leukemia with monocytic differentiation. Twenty-three had other de novo acute myeloid leukemia subtypes. Thirteen patients had other myeloid neoplasms, of which 4 ultimately progressed to an acute myeloid leukemia. Seven had no bone marrow malignancy. Ninety-eight percent of the patients received chemotherapy, and approximately 89% died of causes related to their disease. Cutaneous myeloid sarcoma in most cases represents an aggressive manifestation of acute myeloid leukemia. Diagnosis can be challenging due to lack of myeloblast-associated antigen expression in many cases, and difficulty in distinguishing monocyte-lineage blasts from neoplastic and non-neoplastic mature monocytes.

    C-kit receptor (CD117) and its ligand, stem cell factor, play a key role in normal hematopoiesis. It has been demonstrated that its expression extremely increases in leukemias with myeloid commitment. We analyzed findings on CD117 expression together with other myeloid related markers in 203 de novo acute leukemias, referred to Iranian immunophenotyping centers: Iranian Blood Transfusion Organization (IBTO) and Baghiatallah Hospital (BH). All cases were characterized based on the French American British cooperative group (FAB) and European Group for Immunological Classification of Leukemias (EGIL). The cases comprised of 111 acute myeloblastic leukemia (AML), 86 acute lymphoblastic leukemia (ALL), and 6 acute undifferentiated leukemia (AUL). CD117 was positive in 75 % of AML and 50 % of AUL, whereas none of the ALL cases was positive for this marker. Although CD117 was positive in 100 % of M5a cases, no M5b positive was found (p = 0.036). The calculated specificity for myeloid involvement was 100 % for CD117 and CD33, and 98 % for CD13 and CD15 (p leukemias.

    The t(10;11)(p13;q14) translocation results in the fusion of the CALM (clathrin assembly lymphoid myeloid leukemia protein) and AF10 genes. This translocation is observed in acute myeloblastic leukemia (AML M6), acute lymphoblastic leukemia (ALL) and malignant lymphoma. Using a yeast two-hybrid screen, the four and a half LIM domain protein 2 (FHL2) was identified as a CALM interacting protein. Recently, high expression of FHL2 in breast, gastric, colon, lung as well as in prostate cancer was shown to be associated with an adverse prognosis. The interaction between CALM and FHL2 was confirmed by glutathione S-transferase-pulldown assay and co-immunoprecipitation experiments. The FHL2 interaction domain of CALM was mapped to amino acids 294–335 of CALM. The transcriptional activation capacity of FHL2 was reduced by CALM, but not by CALM/AF10, which suggests that regulation of FHL2 by CALM might be disturbed in CALM/AF10-positive leukemia. Extremely high expression of FHL2 was seen in acute erythroid leukemia (AML M6). FHL2 was also highly expressed in chronic myeloid leukemia and in AML with complex aberrant karyotype. These results suggest that FHL2 may play an important role in leukemogenesis, especially in the case of AML M6

    In clinical practice, the diagnosis and classification of acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) start from the manual examination of stained smears of bone marrow (BM) and peripheral blood (PB) by using an optical microscope. This step is subjective and scarcely reproducible. Therefore, the development of subjective and potentially automatable methods for the recognition of typical AML/MDS cells is necessary. Here we have used Raman spectroscopy for distinguishing myeloblasts, promyelocytes, abnormal promyelocytes and erhytroblasts, which have to be counted for a correct diagnosis and morphological classification of AML and MDS. BM samples from patients affected by four different AML subtypes, mostly characterized by the presence of the four subpopulations selected for this study, were analyzed. First, each cell was scanned by acquiring 4096 spectra, thus obtaining Raman images which demonstrate an accurate description of morphological features characteristic of each subpopulation. Raman imaging coupled with hierarchical cluster analysis permitted the automatic discrimination and localization of the nucleus, the cytoplasm, myeloperoxidase containing granules and haemoglobin. Second, the averaged Raman fingerprint of each cell was analysed by multivariate analysis (principal component analysis and linear discriminant analysis) in order to study the typical vibrational features of each subpopulation and also for the automatic recognition of cells. The leave-one-out cross validation of a Raman-based classification model demonstrated the correct classification of myeloblasts, promyelocytes (normal/abnormal) and erhytroblasts with an accuracy of 100%. Normal and abnormal promyelocytes were distinguished with 95% accuracy. The overall classification accuracy considering the four subpopulations was 98%. This proof-of-concept study shows that Raman micro-spectroscopy could be a valid approach for developing label-free, objective and automatic

    Full Text Available Morphological identification of acute leukemia is a powerful tool used by hematologists to determine the family of such a disease. In some cases, experienced physicians are even able to determine the leukemia subtype of the sample. However, the identification process may have error rates up to 40% (when classifying acute leukemia subtypes depending on the physician's experience and the sample quality. This problem raises the need to create automatic tools that provide hematologists with a second opinion during the classification process. Our research presents a contextual analysis methodology for the detection of acute leukemia subtypes from bone marrow cells images. We propose a cells separation algorithm to break up overlapped regions. In this phase, we achieved an average accuracy of 95% in the evaluation of the segmentation process. In a second phase, we extract descriptive features to the nucleus and cytoplasm obtained in the segmentation phase in order to classify leukemia families and subtypes. We finally created a decision algorithm that provides an automatic diagnosis for a patient. In our experiments, we achieved an overall accuracy of 92% in the supervised classification of acute leukemia families, 84% for the lymphoblastic subtypes, and 92% for the myeloblastic subtypes. Finally, we achieved accuracies of 95% in the diagnosis of leukemia families and 90% in the diagnosis of leukemia subtypes.

    We report a unique pediatric case of hypergranular acute myeloid leukemia with myelodysplasia-related changes. The patient presented with moderate leukocytosis with neutrophilia with left-shift maturation and dysplasia, anemia, and multiple sclerotic bone lesions. The bone marrow was hypercellular with a predominance of myeloblast cells and/or abnormal promyelocytes with hypergranular cytoplasm. Flow cytometric immunophenotyping showed that the leukemic cells were positive for CD13, CD33, and myeloperoxidase, and negative for HLA-DR and CD34. Morphology and immunophenotyping were highly suggestive of acute promyelocytic leukemia. The classic t(15;17) or other RARα rearrangements were not detected by cytogenetic or molecular assays, ruling out acute promyelocytic leukemia. Standard cytogenetic analysis showed that the karyotype of the predominant clone was 47,XY,+6 with evidence of clonal evolution to 47,XY,+6,del(5)(q22q33). A literature and database review showed that trisomy 6 is a rare occurrence in hematological malignancies and, to our knowledge, has never been reported in association with del(5)(q22q33) in a child presenting with hypergranular acute myeloid leukemia with myelodysplasia-related changes. We present a current review of the literature and summarize the clinical features of 57 cases of trisomy 6 as the primary chromosomal abnormality in hematological disease.

    Full Text Available Abstract Background Worldwide, acute leukemia is the most common type of childhood cancer. It is particularly common in the Hispanic populations residing in the United States, Costa Rica, and Mexico City. The objective of this study was to determine the incidence of acute leukemia in children who were diagnosed and treated in public hospitals in Mexico City. Methods Included in this study were those children, under 15 years of age and residents of Mexico City, who were diagnosed in 2006 and 2007 with leukemia, as determined by using the International Classification of Childhood Cancer. The average annual incidence rates (AAIR, and the standardized average annual incidence rates (SAAIR per million children were calculated. We calculated crude, age- and sex-specific incidence rates and adjusted for age by the direct method with the world population as standard. We determined if there were a correlation between the incidence of acute leukemias in the various boroughs of Mexico City and either the number of agricultural hectares, the average number of persons per household, or the municipal human development index for Mexico (used as a reference of socio-economic level. Results Although a total of 610 new cases of leukemia were registered during 2006-2007, only 228 fit the criteria for inclusion in this study. The overall SAAIR was 57.6 per million children (95% CI, 46.9-68.3; acute lymphoblastic leukemia (ALL was the most frequent type of leukemia, constituting 85.1% of the cases (SAAIR: 49.5 per million, followed by acute myeloblastic leukemia at 12.3% (SAAIR: 6.9 per million, and chronic myeloid leukemia at 1.7% (SAAIR: 0.9 per million. The 1-4 years age group had the highest SAAIR for ALL (77.7 per million. For cases of ALL, 73.2% had precursor B-cell immunophenotype (SAAIR: 35.8 per million and 12.4% had T-cell immunophenotype (SAAIR 6.3 per million. The peak ages for ALL were 2-6 years and 8-10 years.

    Acute myeloid leukemia (AML) is a heterogeneous disease. Therefore, various parameters are needed to classify this disease into subtypes, so that specific treatment approaches can be utilized effectively. The commonly used method for diagnosis and classification is based on FAB criteria using morphology and cytochemical stains. For some of the categories, immunophenotyping is necessary. The aim of present study is to determine the frequency of various sub types in acute myeloid leukemia using FAB criteria in our population. This will aid in the correct diagnosis of acute leukemia and hence proper management of the patients. This is descriptive case control study conducted at Aga Khan University Hospital from January 1999 to December 2000. The total number of subjects was 116 that included both adults and children. The patients were diagnosed on the basis of bone marrow morphology using FAB classification. Cytochemistry was done in all cases, while immunophenotyping was considered only in those cases that were found to be problematic. Among 116 patients, 70 were males and 46 were females with male to female ratio 1.5:1. The age ranged between 6 months to 85 years with a mean age of 32 years. AML-M4 was the predominant French-American-British (FAB) subtype (36.2%) followed by M2 (30.25%), M3 (10.4%), M1 (8.7%), M0 (7.7%), M5a (3.5%), M5b (2.5%) and M6 (0.8%). The most common FAB subtype observed in our study was Acute myelomonocytic leukemia (M4) which is in accordance with studies reported from Saudia Arabia and a previous study reported from our institution. However,other national and international studies have reported Myeloblastic Leukemia with maturation (M2) as the predominant subtype of AML.

    Chromosomal translocations involving 11q23 are frequent in infant acute leukemia and give rise to the formation of MLL fusion genes. The mechanism of leukemic transformation by these fusions has been the subject of numerous investigations. However, the dependence of acute leukemia on MLL fusion activity in vivo and the efficacy of targeting this activity to eliminate disease have not been established. We have developed a model for conditional expression of MLL-ENL in hematopoietic progenitor cells, in which expression of the fusion oncogene is turned off by doxycycline. Conditionally immortalized myeloblast cells derived from these progenitors were found to induce leukemia in vivo. Leukemic cells isolated from primary recipient mice were shown to have acquired additional genetic abnormalities and, when transplanted into secondary recipients, induced leukemia with shortened latencies. However, the leukemic cells remained dependent on MLL-ENL expression in vitro and in vivo, and its ablation resulted in regression of established leukemias. This study demonstrates that even genetically complex leukemias can be reversed on inactivation of the initiating MLL fusion and has important implications for the design of novel leukemia therapies.

    Full Text Available The small-molecule inhibitor of murine double minute (MDM-2, Nutlin-3, induced variable apoptosis in primary acute myeloid leukemia (AML blasts, promoted myeloid maturation of surviving cells, as demonstrated by analysis of CD11 b, CD14 surface antigens, by morphologic examination. Although the best-characterized activity of Nutlin-3 is activation of the p53 pathway, Nutlin-3 induced maturation also in one AML sample characterized by p53 deletion, as well as in the p53-/- human myeloblastic HL-60 cell line. At the molecular level, the maturational activity of Nutlin-3 in HL-60 cells was accompanied by the induction of E2F1 transcription factor, it was significantly counteracted by specific gene knockdown with small interfering RNA for E2F1. Moreover, Nutlin-3, as well as tumor necrosis factor (TNF α, potentiated the maturational activity of recombinant TNF-related apoptosis-inducing lig, (TRAIL in HL-60 cells. However, although TNF-α significantly counteracted the proapoptotic activity of TRAIL, Nutlin-3 did not interfere with the proapoptotic activity of TRAIL. Taken together, these data disclose a novel, potentially relevant therapeutic role for Nutlin-3 in the treatment of both p53 wild-type, p53-/- AML, possibly in association with recombinant TRAIL.

    Upfront resistance to chemotherapy and relapse following remission are critical problems in leukemia that are generally attributed to subpopulations of chemoresistant tumor cells. There are, however, limited means for prospectively identifying these subpopulations, which hinders an understanding of therapeutic resistance. BH3 profiling is a functional single-cell analysis using synthetic BCL-2 BH3 domain-like peptides that measures mitochondrial apoptotic sensitivity or "priming." Here, we observed that the extent of apoptotic priming is heterogeneous within multiple cancer cell lines and is not the result of experimental noise. Apoptotic priming was also heterogeneous in treatment-naive primary human acute myeloid leukemia (AML) myeloblasts, and this heterogeneity decreased in chemotherapy-treated AML patients. The priming of the most apoptosis-resistant tumor cells, rather than the median priming of the population, best predicted patient response to induction chemotherapy. For several patients, these poorly primed subpopulations of AML tumor cells were enriched for antiapoptotic proteins. Developing techniques to identify and understand these apoptosis-insensitive subpopulations of tumor cells may yield insights into clinical chemoresistance and potentially improve therapeutic outcomes in AML.

    Full Text Available A facultative heterochromatin mark, histone H3 lysine 9 dimethylation (H3K9me2, which is mediated by histone methyltransferases G9a/GLP (EHMT2/1, undergoes dramatic rearrangements during myeloid cell differentiation as observed by chromatin imaging. To determine whether these structural transitions also involve genomic repositioning of H3K9me2, we used ChIP-sequencing to map genome-wide topography of H3K9me2 in normal human granulocytes, normal CD34+ hematopoietic progenitors, primary myeloblasts from acute myeloid leukemia (AML patients, and a model leukemia cell line K562. We observe that H3K9me2 naturally repositions from the previously designated "repressed" chromatin state in hematopoietic progenitors to predominant association with heterochromatin regions in granulocytes. In contrast, AML cells accumulate H3K9me2 on previously undefined large (> 100 Kb genomic blocks that are enriched with AML-specific single nucleotide variants, sites of chromosomal translocations, and genes downregulated in AML. Specifically, the AML-specific H3K9me2 blocks are enriched with genes regulated by the proto-oncogene ERG that promotes stem cell characteristics. The AML-enriched H3K9me2 blocks (in contrast to the heterochromatin-associated H3K9me2 blocks enriched in granulocytes are reduced by pharmacological inhibition of the histone methyltransferase G9a/GLP in K562 cells concomitantly with transcriptional activation of ERG and ETS1 oncogenes. Our data suggest that G9a/GLP mediate formation of transient H3K9me2 blocks that are preserved in AML myeloblasts and may lead to an increased rate of AML-specific mutagenesis and chromosomal translocations.

    Full Text Available Rupture of the spleen can be classified as spontaneous, traumatic, or pathologic. Pathologic rupture has been reported in infectious diseases such as infectious mononucleosis, and hematologic malignancies such as acute and chronic leukemias. Splenomegaly is considered the most relevant factor that predisposes to splenic rupture. A 66-year-old man with acute myeloid leukemia evolved from an unclassified myeloproliferative neoplasm, complaining of fatigue and mild upper left abdominal pain. He was pale and presented fever and tachypnea. Laboratory analyses showed hemoglobin 8.3 g/dL, white blood cell count 278 × 109/L, platelet count 367 × 109/L, activated partial thromboplastin time (aPTT ratio 2.10, and international normalized ratio (INR 1.60. A blood smear showed 62% of myeloblasts. The immunophenotype of the blasts was positive for CD117, HLA-DR, CD13, CD56, CD64, CD11c and CD14. Lactate dehydrogenase was 2384 U/L and creatinine 2.4 mg/dL (normal range: 0.7-1.6 mg/dL. Two sessions of leukapheresis were performed. At the end of the second session, the patient presented hemodynamic instability that culminated in circulatory shock and death. The post-mortem examination revealed infiltration of the vessels of the lungs, heart, and liver, and massive infiltration of the spleen by leukemic blasts. Blood volume in the peritoneal cavity was 500 mL. Acute leukemia is a rare cause of splenic rupture. Male gender, old age and splenomegaly are factors associated with this condition. As the patient had leukostasis, we hypothesize that this, associated with other factors such as lung and heart leukemic infiltration, had a role in inducing splenic rupture. Finally, we do not believe that leukapheresis in itself contributed to splenic rupture, as it is essentially atraumatic.

    Full Text Available Leukemias rarely debut by pleural involvement as the first manifestation of the hematologic malignancy. This complication is most commonly seen in solid tumors such as carcinomas of the breast, lung, gastrointestinal tract and lymphomas. We present a case of a 66 year old male who presented with a pleural leukemic infiltration of his undiagnosed Acute Myeloid Leukemia that was not a complication of the disease extension, but the acute presentation of the illness. Progressive shortness of breath for two weeks, cough, clear sputum and weight loss were the initial complaints. Serum dyscrasia suggested a hematologic abnormality. A chest x-ray performed demonstrated a buildup of fluid with layering in the left pleural cavity. Diagnostic thoracentesis suggested an exudative etiology with cytology remarkable for 62% leukemic myeloblast. The diagnosis was confirmed by bone marrow biopsy with expression of the antigens CD 34+ and CD13+, with unfavorable cytogenetic prognosis and a trisomy 21 chromosomal defect. Chemotherapy was initiated, though no remission achieved with induction chemotherapy. Complications and disease progression precludes in the patient’s death. Although rare, due to the unusual presentation of the disease, this case clearly demonstrates the importance of biochemical analysis and cytopathology specimens obtained in pleural fluid.

    Hypoxia inducible factor-1α (HIF-1α) is an important transcription factor, which plays a critical role in the formation of solid tumor and its microenvironment. The objective of the present study was to evaluate the expression and function of HIF-1α in human leukemia bone marrow stromal cells (BMSCs) and to identify the downstream targets of HIF-1α. HIF-1α expression was detected at both the RNA and protein levels using real-time PCR and immunohistochemistry, respectively. Vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1α (SDF-1α) were detected in stromal cells by enzyme-linked immunosorbent assay. HIF-1α was blocked by constructing the lentiviral RNAi vector system and infecting the BMSCs. The Jurkat cell/BMSC co-cultured system was constructed by putting the two cells into the same suitable cultured media and conditions. Cell adhesion and secretion functions of stromal cells were evaluated after transfection with the lentiviral RNAi vector of HIF-1α. Increased HIF-1α mRNA and protein was detected in the nucleus of the acute myeloblastic and acute lymphoblastic leukemia compared with normal BMSCs. The lentiviral RANi vector for HIF-1α was successfully constructed and was applied to block the expression of HIF-1α. When HIF-1α of BMSCs was blocked, the expression of VEGF and SDF-1α secreted by stromal cells was decreased. When HIF-1α was blocked, the co-cultured Jurkat cell's adhesion and migration functions were also decreased. Taken together, these results suggest that HIF-1α acts as an important transcription factor and can significantly affect the secretion and adhesion functions of leukemia BMSCs.

The objective of the present study was to evaluate the expression and function of HIF-1α in human leukemia bone marrow stromal cells (BMSCs) and to identify the downstream targets of HIF-1α. HIF-1α expression was detected at both the RNA and protein levels using real-time PCR and immunohistochemistry, respectively. Vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1α (SDF-1α) were detected in stromal cells by enzyme-linked immunosorbent assay. HIF-1α was blocked by constructing the lentiviral RNAi vector system and infecting the BMSCs. The Jurkat cell/BMSC co-cultured system was constructed by putting the two cells into the same suitable cultured media and conditions. Cell adhesion and secretion functions of stromal cells were evaluated after transfection with the lentiviral RNAi vector of HIF-1α. Increased HIF-1α mRNA and protein was detected in the nucleus of the acute myeloblastic and acute lymphoblastic leukemia compared with normal BMSCs. The lentiviral RANi vector for HIF-1α was successfully constructed and was applied to block the expression of HIF-1α. When HIF-1α of BMSCs was blocked, the expression of VEGF and SDF-1α secreted by stromal cells was decreased. When HIF-1α was blocked, the co-cultured Jurkat cell's adhesion and migration functions were also decreased. Taken together, these results suggest that HIF-1α acts as an important transcription factor and can significantly affect the secretion and adhesion functions of leukemia BMSCs

    Full Text Available 550 cases of acute abdomen have been analysed in detail includ-ing their clinical presentation and operative findings. Males are more frequently affected than females in a ratio of 3: 1. More than 45% of patients presented after 48 hours of onset of symptoms. Intestinal obstruction was the commonest cause of acute abdomen (47.6%. External hernia was responsible for 26% of cases of intestinal obstruction. Perforated peptic ulcer was the commonest cause of peritonitis in the present series (31.7% while incidence of biliary peritonitis was only 2.4%.. The clinical accuracy rate was 87%. The mortality in operated cases was high (10% while the over-all mortality rate was 7.5%.

    Acute ileus backgrounds are multiple. Dynamic ileus may take place during peritonitis, some nervous diseases, parathyroid diseases, hysteria. Mechanical ileus is connected with some obstacle in intestines. Small intestines ileus is rarely seen and may be caused by a tumor gall stones, invagination, swallowed foreign bodies. For exclusion of abdominal organs injury and gall stone ileus, if the roentgenological picture isn't clear enough, ultrasonography or computerized tomography of the abdomen are carried out

    Preview Acute anterior nosebleeds are frightening because bleeding is often so copious and seemingly unstoppable. But, ironically, this type is usually less severe than posterior epistaxis, in which blood may run briskly but unseen down the throat. The choice among the many treatment methods available depends on the source and cause of epistaxis. The authors present a methodical approach to patient evaluation and describe the best therapy for various situations.

    2013-01-01

    Full Text Available Granulocytic sarcoma (GS is a rare extramedullary solid tumor defined as an accumulation of myeloblasts or immature myeloid cells. It can cooccur with or precede the acute myeloid leukemia (AML as well as following treated AML. The incidence of GS in AML patients is 3–8% but it significantly rises in M2 FAB subtype AML. This variety of AML harbors t(8;21 in up to 20–25% of cases (especially in children and black ones of African origin and, at a molecular level, it is characterized by the generation of a fusion gene known as RUNX1-RUNX1T1. Approximately 10% of M2 AML patients will develop GS, as a consequence, the t(8;21 and the relative transcript represent the most common cytogenetic and molecular abnormalities in GS. FLT3-ITD mutation was rarely described in AML patients presenting with GS. FLT3 ITD is generally strongly associated with poor prognosis in AML, and is rarely reported in patients with t(8;21. GS presentation is extremely variable depending on organs involved; in general, cranial bones and sinus are very rarely affected sites. We report a rare case of GS occurring as a recurrence of a previously treated t(8;21, FLT3-ITD positive AML, involving mastoid bones and paravertebral tissues.

    Full Text Available Acute Myeloid Leukemia (AML is a type of cancer which attacks white blood cells from myeloid. AML has eight subtypes, namely: M0, M1, M2, M3, M4, M5, M6, and M7. AML subtypes M1, M2 and M3 are affected by the same type of cells, myeloblast, making it needs more detailed analysis to distinguish. To overcome these obstacles, this research is applying digital image processing with Active Contour Without Edge (ACWE and Momentum Backpropagation artificial neural network for AML subtypes M1, M2 and M3 classification based on the type of the cell. Six features required as training parameters from every cell obtained by using feature extraction. The features are: cell area, perimeter, circularity, nucleus ratio, mean and standard deviation. The results show that ACWE can be used for segmenting white blood cells with 83.789% success percentage of 876 total cell objects. The whole AML slides had been identified according to the cell types predicted number through training with momentum backpropagation. Five times testing calibration with the best parameter generated averages value of 84.754% precision, 75.887% sensitivity, 95.090% specificity and 93.569% accuracy.

    Recurrent mutations in isocitrate dehydrogenase 2 ( IDH2 ) occur in ∼12% of patients with acute myeloid leukemia (AML). Mutated IDH2 proteins neomorphically synthesize 2-hydroxyglutarate resulting in DNA and histone hypermethylation, which leads to blocked cellular differentiation. Enasidenib (AG-221/CC-90007) is a first-in-class, oral, selective inhibitor of mutant-IDH2 enzymes. This first-in-human phase 1/2 study assessed the maximum tolerated dose (MTD), pharmacokinetic and pharmacodynamic profiles, safety, and clinical activity of enasidenib in patients with mutant- IDH2 advanced myeloid malignancies. We assessed safety outcomes for all patients and clinical efficacy in the largest patient subgroup, those with relapsed or refractory AML, from the phase 1 dose-escalation and expansion phases of the study. In the dose-escalation phase, an MTD was not reached at doses ranging from 50 to 650 mg per day. Enasidenib 100 mg once daily was selected for the expansion phase on the basis of pharmacokinetic and pharmacodynamic profiles and demonstrated efficacy. Grade 3 to 4 enasidenib-related adverse events included indirect hyperbilirubinemia (12%) and IDH-inhibitor-associated differentiation syndrome (7%). Among patients with relapsed or refractory AML, overall response rate was 40.3%, with a median response duration of 5.8 months. Responses were associated with cellular differentiation and maturation, typically without evidence of aplasia. Median overall survival among relapsed/refractory patients was 9.3 months, and for the 34 patients (19.3%) who attained complete remission, overall survival was 19.7 months. Continuous daily enasidenib treatment was generally well tolerated and induced hematologic responses in patients for whom prior AML therapy had failed. Inducing differentiation of myeloblasts, not cytotoxicity, seems to drive the clinical efficacy of enasidenib. This trial was registered at www.clinicaltrials.gov as #NCT01915498. © 2017 by The American Society

    This study aimed to analyze the associations between childhood acute leukemia (AL) and maternal caffeinated beverage consumption during pregnancy, and to explore interactions between caffeinated and alcoholic beverage consumption and polymorphisms of enzymes involved in caffeine and ethanol metabolisms. The data were generated by the French ESCALE study, which included 764 AL cases and 1,681 controls in 2003-2004. The case and control mothers were interviewed on their consumption habits during pregnancy using a standardized questionnaire. Genotypes of the candidate alleles (NAT2*5 rs1801280, ADH1C*2 rs698 and rs1693482, CYP2E1*5 rs2031920 and rs3813867) were obtained using high-throughput genotyping and imputation data for 493 AL cases and 549 controls with at least two grandparents born in Europe. Maternal regular coffee consumption during pregnancy was associated with childhood AL (OR = 1.2 [1.0-1.5], p = 0.02); the odds ratios increased linearly with daily intake (p for trend 2 cups per day vs. no or less than 1 cup per week: AL: OR = 1.6 [1.2-2.1], lymphoblastic AL: OR = 1.5 [1.1-2.0], myeloblastic AL: OR = 2.4 [1.3-4.3]). The association was slightly more marked for children born to non-smoking mothers. Lymphoblastic AL was also associated with cola soda drinking (OR = 1.3 [1.0-1.5], p = 0.02). No significant gene-environment interactions with coffee, tea, cola soda, or alcohol drinking were observed. This study provides additional evidence that maternal coffee consumption during pregnancy may be associated with childhood AL. Coffee consumption is a prevalent habit and its potential involvement in childhood AL needs to be considered further.

    Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

    Acute otitis externa, also known as ‘swimmer’s ear’, is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

  3. Minimally-Myelosuppressive Asparaginase-Containing Induction Regimen for Treatment of a Jehovah’s Witness with mutant IDH1/NPM1/NRAS Acute Myeloid Leukemia

    Full Text Available Treatment of patients with acute myeloid leukemia (AML who do not wish to accept blood product transfusion, including Jehovah’s Witnesses, is extremely challenging. The use of conventional chemotherapy for induction of complete remission (CR results in profound anemia and thrombocytopenia requiring frequent transfusions of blood products, without which such treatment will be life-threatening. Finding a well tolerable, minimally myelosuppressive induction regimen for such patients with AML is a clear example of area of unmet medical need. Here, we report a successful treatment of a 52-year-old Jehovah’s Witness with newly diagnosed AML with peg-asparaginase, vincristine and methylprednisolone. The AML was characterized with normal karyotype, and mutations in isocitrate dehydrogenase 1 (IDH1-Arg132Ser, nucleophosmin 1 (NPM1-Trp289Cysfs*12 and neuroblastoma RAS viral oncogene homolog (NRAS-G1y12Va1. After one 28-day cycle of treatment, the patient achieved complete remission with incomplete count recovery (CRi and after the second cycle, he achieved CR with full blood count recovery. The patient has never received any blood products. Notwithstanding that myeloperoxidase-induced oxidative degradation of vincristine results in its lack of activity as monotherapy in AML, its combination with corticosteroid and asparaginase has resulted in a robust remission in this patient. Diminished steroid clearance by asparaginase activity as well as reduction in serum glutamine level induced by glutaminase enzymatic activity of asparaginase may have contributed to effective killing of the myeloblasts that carry IDH1/NPM1/NRAS mutations. In conclusion, asparaginase-containing regimens, which are approved for treatment of acute lymphoblastic leukemia (ALL but not AML, can be used to treat patients with AML who do not accept blood transfusion.

    Pulsed electromagnetic field (PEMF) influenced the viability of proliferating in vitro peripheral blood mononuclear cells (PBMCs) isolated from Crohn's disease patients as well as acute myeloblastic leukemia (AML) patients by induction of cell death, but did not cause any vital changes in cells from healthy donors. Experiments with lymphoid U937 and monocytic MonoMac6 cell lines have shown a protective effect of PEMF on the death process in cells treated with death inducers. The aim of the current study was to investigate the influence of PEMF on native proliferating leukocytes originating from newly diagnosed acute lymphoblastic leukemia (ALL) patients. The effects of exposure to PEMF were studied in PBMCs from 20 children with ALL. PBMCs were stimulated with three doses of PEMF (7 Hz, 30 mT) for 4 h each with 24 h intervals. After the last stimulation, the cells were double stained with annexin V and propidium iodide dye to estimate viability by flow cytometric analysis. The results indicated an increase of annexin V positive as well as double stained annexin V and propidium iodide positive cells after exposure to threefold PEMF stimulation. A low-frequency pulsed electromagnetic field induces cell death in native proliferating cells isolated from ALL patients. The increased vulnerability of proliferating PBMCs to PEMF-induced interactions may be potentially applied in the therapy of ALL. The analysis of expression of apoptosis-related genes revealed changes in mRNA of some genes engaged in the intrinsic apoptotic pathway belonging to the Bcl-2 family and the pathway with apoptosis-inducing factor (AIF) abundance upon PEMF stimulation of PBMCs.

    The incidence of acute erythroid leukemia subtype (AEL) is rare, accounting for 5% of cases of acute myeloid leukemia (AML), and the outcome is dismal. However, in 2016 revision to the WHO classification, the subcategory of AEL has been removed. Myeloblasts are redefined as the percentage of total marrow cells, not non-erythroid cells. Therefore, the previously diagnosed AEL cases are currently diagnosed as AML or myelodyspalstic syndrome (MDS) according to new criteria. We respectively reviewed cases of 97 de novo previously diagnosed AEL and all the patients were diagnosed as AML or MDS according to the new classification scheme, and then the clinical characteristics of these two subtypes were compared. Statistical analyses were performed by SPSS software version 18.0. The median age was 37 years-old, the two-thirds of previous AEL cases were diagnosed as MDS, and there was no obvious difference between two subtypes except for male/female ratio and age. Cytogenetic, rather than MDS/AML subtypes, can better represent the prognostic factor of previously diagnosed AEL patients. When the cytogenetic risk of patients belonged to MRC intermediate category and age were below 40 years-old in previous AEL cases, the patients who received induction chemotherapy without transplantation had a similar survival compared with the patients who underwent transplantation (3-year OS: 67.2% vs 68.5%). Cytogenetic, rather than MDS/AML subtypes, can better represent the prognostic factor of previously diagnosed AEL patients. Transplantation was a better choice for those whose cytogenetic category was unfavorable.

    We describe the case of a 45-year-old Japanese man who developed acute pericarditis following an acute pulmonary thromboembolism. He had developed shortness of breath 7 days prior to hospitalization and was admitted with severe dyspnea. Echocardiography and laboratory results were compatible with acute pulmonary thromboembolism, which was confirmed by contrast-enhanced chest computed tomography. On the third hospital day, he experienced chest pain exacerbated by inspiration. On the fourth hospital day, his body temperature increased to 39°C and echocardiography revealed circumferential pericardial effusion. A diagnosis of acute pericarditis was made and the patient was treated with colchicine and aspirin. On the fifth hospital day, his symptoms largely subsided. Auscultation revealed pericardial friction rub. Electrocardiography demonstrated diffuse ST-segment elevations. Twenty-four days later, computed tomography revealed the disappearance of both the pericardial effusion and pulmonary arterial emboli. This case was thought to be one of acute pericarditis following acute pulmonary thromboembolism.

    Acute pancreatitis is an acute inflammation of the pancreas. Several classification systems have been used in the past but were considered unsatisfactory. A revised Atlanta classification of acute pancreatitis was published that assessed the clinical course and severity of disease; divided acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis; discerned an early phase (first week) from a late phase (after the first week); and focused on systemic inflammatory response syndrome and organ failure. This article focuses on the revised classification of acute pancreatitis, with emphasis on imaging features, particularly on newly-termed fluid collections and implications for the radiologist.

    Acute cor pulmonale is a form of acute right heart failure produced by a sudden increase in resistance to blood flow in the pulmonary circulation, which is now rapidly recognized by bedside echocardiography. In the clinical setting, acute cor pulmonale is mainly observed as a complication of massive pulmonary embolism or acute respiratory distress syndrome. In acute respiratory distress syndrome, the worsening effect of mechanical ventilation has been recently emphasized. As a general rule, the treatment consists in rapidly reducing resistance to blood flow in the pulmonary circulation, obtained by a specific strategy according to etiology.

    Fundamental studies of leukemic cell labeling with 111 In-oxine and their applications to leukemic cell kinetics in five patients with acute myeloblastic leukemia (AML) were examined. Labeling efficiency of leukemic cells was 80.3 +- 3.6% for more than 1 x 10 8 cells at room temperature for 20 minutes of incubation followed by two times washes. Cell viability determined by means of trypanblue exclusion test was 95.3 +- 2.6%. In vitro elution rate of 111 In from the labeled cells during 12 hours was 10.0 +- 1.2%. The disappearance curves of labeled leukemic cells in AMLs followed a single exponential fashion, and the half time of disappearance (T 1/2) ranged from 9.6 to 31.8 hours. Total blood leukemic cell pool (TBLCP) calculated with the dilution principles of radioisotopes correlated significantly with the leukemic cell counts (LC) in the peripheral blood (Y = 0.32 + 1.94X, r = 0.99). In the studies of organ distribution which were observed and analized with gamma camera and computer, labeled leukemic cells passed through lungs within 15 minutes. Radioactivity in the spleen increased rapidly for 30 - 60 minutes, then reached a plateau. Hepatic radioactivity showed a temporary decrease during 10 - 60 minutes following the moderate accumulation in initial 10 minutes. In two cases, bone marrow was visualized 24 hours after the injection. Radioactivity of the leukemic cells isolated from the bone marrow at 22 hours after the injection in one case was one third of the radioactivity in leukemic cells obtained from the peripheral blood at the same time.

    A review of the systemic acute phase reaction with major cytokines involved, and the hepatic metabolic changes, negative and positive acute phase proteins (APPs) with function and associated pathology is given. It appears that APPs represent appropriate analytes for assessment of animal health. Whereas they represent non-specific markers as biological effect reactants, they can be used for assessing nutritional deficits and reactive processes, especially when positive and negative acute phase variables are combined in an index. When such acute phase index is applied to separate healthy animals from animals with some disease, much better results are obtained than with single analytes and statistically acceptable results for culling individual animals may be reached. Unfortunately at present no cheap, comprehensive and easy to use system is available for assessing various acute phase proteins in serum or blood samples at the same time. Protein microarray or fluid phase microchip technology may satisfy this need; and permit simultaneous analysis of numerous analytes in the same small volume sample and enable integration of information derived from systemic reactivity and nutrition with disease specific variables.

    This study describes clinical, laboratory, and electrodiagnostic features of a severe acute axonal polyneuropathy common to patients with acute nutritional deficiency in the setting of alcoholism, bariatric surgery (BS), or anorexia. Retrospective analysis of clinical, electrodiagnostic, and laboratory data of patients with acute axonal neuropathy. Thirteen patients were identified with a severe, painful, sensory or sensorimotor axonal polyneuropathy that developed over 2-12 weeks with sensory ataxia, areflexia, variable muscle weakness, poor nutritional status, and weight loss, often with prolonged vomiting and normal cerebrospinal fluid protein. Vitamin B6 was low in half and thiamine was low in all patients when obtained before supplementation. Patients improved with weight gain and vitamin supplementation, with motor greater than sensory recovery. We suggest that acute or subacute axonal neuropathy in patients with weight loss or vomiting associated with alcohol abuse, BS, or dietary deficiency is one syndrome, caused by micronutrient deficiencies.

    2015-09-01

    Acute agitation psychiatric emergencies as frequently occur in psychiatric as well as in non-psychiatric settings, such as general hospitals, specialized clinics, emergency services and private practices. Psychiatric emergencies can be life-threatening and necessitate immediate treatment. This article presents the core symptomatology, differential diagnoses and treatment options of acute agitation emergencies. Case control studies and reliable data regarding prevalence and treatment of acute agitation in psychiatric and general hospitals or private practices are sparse. Existing evidence suggests that optimization of diagnosis and therapy of psychiatric emergencies, such as acute agitation is warranted. Treatment of acute agitation, psychological distress and other psychiatric emergencies are highly demanding regarding psychiatric expertise and concerning the personality and behavior of the therapist. The basis of therapy comprises the ability to form a stable and trustworthy relationship with the patient as well as to patiently calm down agitated patients. Unambiguous and rapid decision-making that takes effective pharmacological treatment options into account usually leads to swift amelioration of the acute symptomatology.

  16. Functional characterization of FLT3 receptor signaling deregulation in acute myeloid leukemia by single cell network profiling (SCNP.

    Directory of Open Access Journals (Sweden)

    David B Rosen

    Full Text Available BACKGROUND: Molecular characterization of the FMS-like tyrosine kinase 3 receptor (FLT3 in cytogenetically normal acute myeloid leukemia (AML has recently been incorporated into clinical guidelines based on correlations between FLT3 internal tandem duplications (FLT3-ITD and decreased disease-free and overall survival. These mutations result in constitutive activation of FLT3, and FLT3 inhibitors are currently undergoing trials in AML patients selected on FLT3 molecular status. However, the transient and partial responses observed suggest that FLT3 mutational status alone does not provide complete information on FLT3 biological activity at the individual patient level. Examination of variation in cellular responsiveness to signaling modulation may be more informative. METHODOLOGY/PRINCIPAL FINDINGS: Using single cell network profiling (SCNP, cells were treated with extracellular modulators and their functional responses were quantified by multiparametric flow cytometry. Intracellular signaling responses were compared between healthy bone marrow myeloblasts (BMMb and AML leukemic blasts characterized as FLT3 wild type (FLT3-WT or FLT3-ITD. Compared to healthy BMMb, FLT3-WT leukemic blasts demonstrated a wide range of signaling responses to FLT3 ligand (FLT3L, including elevated and sustained PI3K and Ras/Raf/Erk signaling. Distinct signaling and apoptosis profiles were observed in FLT3-WT and FLT3-ITD AML samples, with more uniform signaling observed in FLT3-ITD AML samples. Specifically, increased basal p-Stat5 levels, decreased FLT3L induced activation of the PI3K and Ras/Raf/Erk pathways, decreased IL-27 induced activation of the Jak/Stat pathway, and heightened apoptotic responses to agents inducing DNA damage were observed in FLT3-ITD AML samples. Preliminary analysis correlating these findings with clinical outcomes suggests that classification of patient samples based on signaling profiles may more accurately reflect FLT3 signaling

  17. Differentiating Acute Otitis Media and Acute Mastoiditis in Hospitalized Children.

    Laulajainen-Hongisto, Anu; Aarnisalo, Antti A; Jero, Jussi

    2016-10-01

    Acute otitis media is a common infection in children. Most acute otitis media episodes can be treated at an outpatient setting with antimicrobials, or only expectant observation. Hospital treatment with parenteral medication, and myringotomy or tympanostomy, may be needed to treat those with severe, prolonged symptoms, or with complications. The most common intratemporal complication of acute otitis media is acute mastoiditis. If a child with acute mastoiditis does not respond to this treatment, or if complications develop, further examinations and other surgical procedures, including mastoidectomy, are considered. Since the treatment of complicated acute otitis media and complicated acute mastoiditis differs, it is important to differentiate these two conditions. This article focuses on the differential diagnostics of acute otitis media and acute mastoiditis in children.

    The study included 78 pregnant women with acute pancreatiis. Group 1 contained 43 4-37 weeks pregnant women and group 2 35 non-pregnant women. Control group was comprised of 30 women with physiological pregnancy. Comparative analysis of peculiarities of the clinical course of acute pancreatitis showed its similar manifestations in all three groups. However pregnancy itself variability of pancreatitis symptoms and their similarity to those of other acute surgical and obstetric pathologies, high (25.6) percent ofpainlessforms, late detection and inadequate treatment pose difficultiesfor diagnostics and delay the onset of pathogenetic therapy. The study of endogenous intoxication markers (leukocytic index, medium molecular weight molecules, circulating immune complexes, total endotoxins) revealed endotoxicosis in the pregnant women with acute pancreatitis that has negative effect on the fetoplacental complex and the development of pregnancy; moreover pancreatitis increases the risk of premature delivery up to 79.21%. The results of the study dictate the necessity of the searchfor new safe treatment and rehabilitation modalities for ptregnant women with acute pancreatitis.

    2011-10-01

    Acute pancreatitis in pregnancy is a rare condition estimated to occur in 1 per 1000 to 1 per 12,000 pregnancies. The most frequent etiology in pregnancy is biliary, followed by hyperlipidemia and/or alcohol abuse. Abdominal ultrasound and endoscopic ultrasound are ideal imaging techniques for diagnosing disease because they have no radiation risk. Computed tomography, magnetic resonance cholangiopancreatography, and endoscopic retrograde cholangiopancreatography should be used with caution. Treatment could be conservative or surgical, and standard algorithms are slightly modified in pregnant women. In the last decades the outcome of acute pancreatitis in pregnancy is much better, and perinatal mortality is less than 5%.

    Acute calcific tendinitis results from the deposition of calcium hydroxyapatite crystals in peri articular muscular attachments. It usually develops in extremities, most often in shoulders and hips. Although the incidence is much lower, it has been reported to occur in the neck region, where it involves the tendons insertion of the longs colli muscle. We present a case of acute neck pain caused by a calcareous deposition in the tendon of the longs colli muscle, producing inflammation.

The virus was important from Nigeria. The patients suffered by the acute hemorrhagic keratoconjuntivitis with transient iritic irritation without the systemic symptoms. Since now this disease with serological verification was not diagnosed in our country. The question of the viral hemorrhagic conjunctivitis and their treatment is discussed. The necessity of virological investigation in inflammations of the anterior segment is stressed.

    2016-12-01

    Pediatric acute liver failure (ALF) is a complex and rapidly progressive syndrome that results from a variety of age-dependent etiologies. It is defined by the acute onset of liver disease with no evidence of chronic liver disease. There must be biochemical or clinical evidence of severe liver dysfunction as defined by an international normalized ratio (INR) ≥2. If hepatic encephalopathy is present, INR should be ≥1.5. Unfortunately, due to the rarity of ALF in pediatric patients, there is a paucity of diagnostic and management algorithms and each patient must have an individualized approach.

    The results of CT in 100 patients with acute hemiplegia in childhood are reported here. The etiology was various: 2 patients had infratentorial brain tumors, 56 had cerebral vascular diseases, 3 had head injuries, 16 had intracranial infectious diseases, one had postinfectious encephalomyelitis, one had multiple sclerosis, 2 had epilepsy, and the diagnosis of 19 were unknown. Eleven patients had a normal CT and a good prognosis. As for the type of onset, there were patients of type 1 with fever and 42 with convulsions and unconsciousness; those of type 2 with convulsions and unconsciousness were 12, and those of type 3 without fever and convulsions were 46. This classification is assumed to be useful, as the type of onset is characteristic of the etiology. Six patients were diagnosed correctly by repeated examinations, although the first CT did not reveal any remarkable findings. Capsular infarction, occlusion of the posterior cerebral artery in acute hemiplegia in childhood, abnormal findings of the internal capsule, thalamus, and midbrain in a patient with postinfectious encephalomyelitis, and a diffuse low density in the CT of the unilateral hemisphere in the patients with acute encephalopathy and acute hemiplegia of an obscure origin have been found after the introduction of computerized tomography.

    1988-02-01

    Information on acute intoxications during work in the Netherlands has been gathered from 4 sources during a 1-year period: 1. The registration of occupational accidents of the Directorate-General of Labour, by reviewing reports on accidents involving chemicals; 2. The Netherlands Poison Control Centre of the National Institute for Public Health and Environmental Hygiene, by tracing back consulting physicians; 3. The Dutch Centre for Health Care Information, by searching their data base for hospital admissions with relevant admission diagnoses and 4. A large Occupational Health Service, which for this purpose recorded incident cases in the population under care. During the period of investigation 5 deaths were reported: 1 case of hydrogen cyanide intoxication, 1 case of carbon dioxide intoxication, and 3 cases of hydrogen sulfide intoxication in combination with oxygen deficiency (nearby a liquid manure tank). At least 690 (supposed) acute intoxications during work occurred, which in 84 cases resulted in hospital admission. The total number of hospital admissions for supposed unintentional acute intoxications by chemicals, usually encountered in workplaces, in the Netherlands in 1984 was at least 477. Substances most often involved belonged to the groups of pesticides, lung and/or skin irritant liquids/vapors/gases and asphyxiants. The working branches most often involved were agriculture and market gardening sectors, (chemical) industries, repair and retail trade and some governmental services (police, fire brigade, defense personnel). The results show considerable underreporting in official statistics on acute intoxications during work.

    2014-06-01

    This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute

    Full Text Available Symptoms and signs of acute pyelonephritis sometimes are subtle and emergency physicians attending overcrowded and busy institutions could easily miss the right diagnosis. The presence of a renal damage is decisive in the therapeutic choice. Aims of our study are: 1 to assess prevalence of renal damage in patients presenting to our ED with symptoms and signs of primary urinary tract infection (UTI; 2 to evaluate the reliability of such symptoms and signs in predicting a renal damage; 3 to assess accuracy of the contrast enhanced ultrasound (CEUS in the ED diagnosis of renal damage due to acute uncomplicated pyelonephritis. We studied 54 patients with suspected UTI. Each patient underwent clinical examination, routine blood and urine sampling and conventional renal ultrasound (US. 23 patients had confirmation of acute primary UTI, and performed renal magnetic resonance (MR to rule out renal parenchymal involvement. In 16 patients (69,6% one or more parenchymal lesions were visualized at MR, and diagnosis of acute uncomplicated pyelonephritis was confirmed (group A. The other 7 patients had a diagnosis of UTI without renal involvement (group B. Some of 23 patients presented with few atypical symptoms. Lumbar pain was the most frequent symptom (n = 21, without a statistically significant difference between group A and B (P 0,958; p = 0,328. No other symptom or sign has demonstrated statistically valid in predicting the renal involvement. Renal US was positive in only 3 patients of group A (18,7%. During this first part of our study, CEUS was performed in a limited number of patients (n = 8, and in 7 examinations data were concordant with MR. In conclusion, analysis of our preliminary data confirms that a distinction between patients with different extension of the UTI is not possible through the simple clinical examination and routine tests.

    Background Hordeolum is an acute, purulent inflammation of the eyelid margin usually caused by obstructed orifices of the sebaceous glands of the eyelid. The condition, which affects sebaceous glands internally or externally, is common. When the meibomian gland in the tarsal plate is affected, internal hordeolum occurs, while when the glands of Zeis or Moll associated with eyelash follicles are affected, external hordeolum, or stye occurs. The onset of hordeolum is usually self limited, and may resolve in about a week with spontaneous drainage of the abscess. When the condition is severe, it can spread to adjacent glands and tissues. Recurrences are very common. As long as an internal hordeolum remains unresolved, it can develop into a chalazion or generalized eyelid cellulitis. Acupuncture is a traditional Chinese medical therapy aimed to treat disease by using fine needles to stimulate specific points on the body. However, it is unclear if acupuncture is an effective and safe treatment for acute hordeolum. Objectives The objective of this review was to investigate the effectiveness and safety of acupuncture to treat acute hordeolum compared with no treatment, sham acupuncture, or other active treatment. We also compared the effectiveness and safety of acupuncture plus another treatment with that treatment alone. Search methods We searched CENTRAL, Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE, Embase, PubMed, Latin American and Caribbean Health Sciences Literature Database (LILACS), three major Chinese databases, as well as clinical trial registers all through 7 June 2016. We reviewed the reference lists from potentially eligible studies to identify additional randomised clinical trials (RCTs). Selection criteria We included RCTs of people diagnosed with acute internal or external hordeola. We included RCTs comparing acupuncture with sham acupuncture or no treatment, other active treatments, or

    Full Text Available The acute-phase response (APR is a prominent systemic reaction of the organism to local or systemic disturbances in its homeostasis caused by infection, tissue injury, trauma or surgery, or immunological disorders. The tissue macrophage is most commonly regarded as initiating the APR through direct stimulation and secretion of various cell communicating factors. Proinflammatory cytokines and mediators are significantly elevated with gingival inflammation and during the destructive phase of periodontitis. Cytokines appear to play a major role in the clinical symptoms and tissue destruction associated with progressing periodontitis. Many of these cytokines are derived from activated macrophages and can act both locally and distally to amplify cytokine production from other cell types. The host responses to periodontal disease and cardiovascular diseases were reflected by an increase in the acute-phase proteins (serum amyloid A and C-reactive protein.

    2014-07-01

    Full Text Available Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci is the only agent that requires an etiologic diagnosis and specific treatment. S. pyogenes is of major clinical importance because it can trigger post-infection systemic complications, acute rheumatic fever, and post-streptococcal glomerulonephritis. Symptom onset in streptococcal infection is usually abrupt and includes intense sore throat, fever, chills, malaise, headache, tender enlarged anterior cervical lymph nodes, and pharyngeal or tonsillar exudate. Cough, coryza, conjunctivitis, and diarrhea are uncommon, and their presence suggests a viral cause. A diagnosis of pharyngitis is supported by the patient's history and by the physical examination. Throat culture is the gold standard for diagnosing streptococcus pharyngitis. However, it has been underused in public health services because of its low availability and because of the 1- to 2-day delay in obtaining results. Rapid antigen detection tests have been used to detect S. pyogenes directly from throat swabs within minutes. Clinical scoring systems have been developed to predict the risk of S. pyogenes infection. The most commonly used scoring system is the modified Centor score. Acute S. pyogenes pharyngitis is often a self-limiting disease. Penicillins are the first-choice treatment. For patients with penicillin allergy, cephalosporins can be an acceptable alternative, although primary hypersensitivity to cephalosporins can occur. Another drug option is the macrolides. Future perspectives to prevent streptococcal pharyngitis and post-infection systemic complications include the development of an anti-Streptococcus pyogenes vaccine.

    To describe the clinical and laboratory features of benign acute childhood myositis. 40 children of BACM were seen during October 2001 to February 2002, 22 (52%) were male with mean age of 5.3 years. Duration of illness was 3.97 days. Preceding symptoms included fever, leg pain, vomiting and inability to walk. A provisional diagnosis of viral myositis was made in 26 (66%). Guillian Barre Syndrome was the most common referral diagnosis. 11 (27.5%) children had leucopenia with lymphocytic response and 16 (40%) had thrombocytopenia. CRP was negative in 32 (80%). CPK was markedly elevated (more than 1000 IU/l) in 18 (45%) and more than 500 IU/l in 11 (27.5%) remaining between 200 to 500 IU/l. Associated features were hepatitis (elevated SGOT & SGPT) in 28 (70%) and shock in 5 (12.5%). Serological test were indicative of dengue virus (Elisa PAN BIO) in 20 (50%) of which 8 (25%) were primary dengue and 12 (30%) were secondary dengue. The outcome of therapy mainly supportive were excellent. Benign acute myositis occurs often in association with viral infection. In the present study, Dengue virus was positive in 20 (50%) children. Benign acute myositis can be differentiated from more serious causes of walking difficulty by presence of calf and thigh muscle tenderness on stretching, normal power and deep tendon reflex and elevated CPK.

  15. Perioperative acute renal failure.

    Mahon, Padraig

    2012-02-03

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

  17. Icam-1 and acute pancreatitis complicated by acute lung injury.

    Science.gov (United States)

    Zhang, XiPing; Wu, Dijiong; Jiang, Xinge

    2009-01-08

    One of the most common complications of acute pancreatitis is acute lung injury, during which intercellular adhesion molecule-1 (ICAM-1) plays an important role by participating in leukocyte adhesion and activation as well as by inducing the "cascade effect" of inflammatory mediators, pulmonary microcirculation dysfunction and even acute respiratory distress syndrome, multiple organ failure or death. Although it is generally believed that the modulatory mechanism of ICAM-1 during this process is associated with the activation of nuclear transcription factor kappa B which is mediated by IL-1, IL-6, IL-18 and oxygen free radical, etc., further studies are still required to clarify it. Since the upregulation of ICAM-1 expression in the lung during acute lung injury is one of main pathogeneses, the early detection of the ICAM-1 expression level may contribute to the prevention and treatment of acute lung injury. Moreover, reducing pulmonary ICAM-1 expression levels through treatment with anti-ICAM-1 monoclonal antibody (aICAM-1) and antagonists of the neurokinin 1 receptor, etc., should have a positive effect on protecting the lungs during acute pancreatitis. This review aims to further clarify the relationship between ICAM-1 and acute pancreatitis complicated by acute lung injury, and therefore provides a theoretical basis for the formulation of corresponding therapeutic measures in clinical practice for acute pancreatitis.

    The term acute aortic syndrome comprises aortic dissection, intramural hematoma, and penetrating atherosclerotic ulcer. The most recent developments in acute aortic syndromes include (1) a change in the mindset that each entity is pathologically distinct, with a shift toward considering the acute aortic syndromes as points along a spectrum of aortic disease, (2) the optimization of aortic imaging quality and radiation dose, and (3) surgical or endovascular management. This review article focuses on how these developments pertain to thoracic radiologists.

    The literature of acute exacerbation of chronic obstructive pulmonary disease (COPD) is fast expanding. This review focuses on several aspects of acute exacerbation of COPD (AECOPD) including epidemiology, diagnosis and management. COPD poses a major health and economic burden in the Asia-Pacific region, as it does worldwide. Triggering factors of AECOPD include infectious (bacteria and viruses) and environmental (air pollution and meteorological effect) factors. Disruption in the dynamic balance between the 'pathogens' (viral and bacterial) and the normal bacterial communities that constitute the lung microbiome likely contributes to the risk of exacerbations. The diagnostic approach to AECOPD varies based on the clinical setting and severity of the exacerbation. After history and examination, a number of investigations may be useful, including oximetry, sputum culture, chest X-ray and blood tests for inflammatory markers. Arterial blood gases should be considered in severe exacerbations, to characterize respiratory failure. Depending on the severity, the acute management of AECOPD involves use of bronchodilators, steroids, antibiotics, oxygen and noninvasive ventilation. Hospitalization may be required, for severe exacerbations. Nonpharmacological interventions including disease-specific self-management, pulmonary rehabilitation, early medical follow-up, home visits by respiratory health workers, integrated programmes and telehealth-assisted hospital at home have been studied during hospitalization and shortly after discharge in patients who have had a recent AECOPD. Pharmacological approaches to reducing risk of future exacerbations include long-acting bronchodilators, inhaled steroids, mucolytics, vaccinations and long-term macrolides. Further studies are needed to assess the cost-effectiveness of these interventions in preventing COPD exacerbations. © 2016 Asian Pacific Society of Respirology.

    2010-05-01

    Stroke is the third most common cause of death in the United States and is the number one cause of long-term disability. Legislative mandates, largely the result of the American Heart Association, American Stroke Association, and Brain Attack Coalition working cooperatively, have resulted in nationwide standardization of care for patients who experience a stroke. Transport to a skilled facility that can provide optimal care, including immediate treatment to halt or reverse the damage caused by stroke, must occur swiftly. Admission to a certified stroke center is recommended for improving outcomes. Most strokes are ischemic in nature. Acute ischemic stroke is a heterogeneous group of vascular diseases, which makes targeted treatment challenging. To provide a thorough review of the literature since the 2007 acute ischemic stroke guidelines were developed, we performed a search of the MEDLINE database (January 1, 2004-July 1, 2009) for relevant English-language studies. Results (through July 1, 2009) from clinical trials included in the Internet Stroke Center registry were also accessed. Results from several pivotal studies have contributed to our knowledge of stroke. Additional data support the efficacy and safety of intravenous alteplase, the standard of care for acute ischemic stroke since 1995. Due to these study results, the American Stroke Association changed its recommendation to extend the time window for administration of intravenous alteplase from within 3 hours to 4.5 hours of symptom onset; this recommendation enables many more patients to receive the drug. Other findings included clinically useful biomarkers, the role of inflammation and infection, an expanded role for placement of intracranial stents, a reduced role for urgent carotid endarterectomy, alternative treatments for large-vessel disease, identification of nontraditional risk factors, including risk factors for women, and newly published pediatric stroke guidelines.

Diverticulitis is defined as an inflammation of the diverticulum, which can be asymptomatic or symptomatic. This disease is the third most common gastrointestinal illness that requires hospitalization and the leading indication for elective colon resection. Abdominal pain is the most common complaint in patients with acute diverticulitis. The pain can be described as cramping, constant, and persistent for several days. Medical management is most often provided with antibiotics and clear liquid diet. Copyright © 2017 Elsevier Inc. All rights reserved.

    Acute appendicitis occurs as a complication of pregnancy in about 0.1 per cent of cases. Diagnosis may be somewhat more difficult during the second and third trimesters dur to the displacement of viscera and the increased incidence of pyelitis and constipation. It is based on the same symptoms and signs as in nonpregnant patients. The treatment is immediate operation regardless of the stage of pregnancy. A McBurney incision is preferred and it is placed somewhat higher than usual in the later stages of pregnancy. When operation is done promptly there is little danger to either mother or fetus.

    One in 4 children will have at least 1 episode of acute otitis media (AOM) by age 10 years. AOM results from infection of fluid that has become trapped in the middle ear. The bacteria that most often cause AOM are Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Differentiating AOM from otitis media with effusion (OME) is a critical skill for physicians, as accurate diagnosis will guide appropriate treatment of these conditions. Although fluid is present in the middle ear in both conditions, the fluid is not infected in OME as is seen in AOM patients. Copyright © 2014 Elsevier Inc. All rights reserved.

She returned to baseline after each seizure, had no obvious signs of trauma, and did not exhibit any focal neurologic deficits. She denied illicit drugs or new medications. A family member noted that she had fallen from her bed (approximately 3 feet high 2 days ago. Significant findings: Non-contrast Computed Tomography (CT of the Head showed a dense extra-axial collection along the left frontal and parietal regions, extending superior to the vertex with mild mass effect, but no midline shift. Discussion: Intracranial hemorrhage (ICH is a term to describe any abnormal bleeding within the bony confines of the skull. Most commonly, subdural hemorrhages (SDH result from injury to the bridging veins that lead to bleeding between the dura and arachnoid maters. However, in 20%-30% of cases an arterial source of bleeding can be found.1 For adults, motor vehicle collisions and other unintentional head trauma are typically the provoking factors in developing SDH. Falls in the elderly are a common cause of SDH since diffuse cerebral atrophy leads to increased shear forces upon vasculature structures during the fall. The risk of SDH increases with the use of anti-thrombotic agents.2 Clinical presentation varies from asymptomatic to coma (in 50 percent of acute SDH. Chronic SDH may present with headaches, light-headedness, cognitive impairment, and seizures.1 The risk of posttraumatic epileptic seizures (PTS is higher in acute SDH. Risk factors for acute SDH PTS include low Glasgow Coma Score and craniotomy, whereas risk factors for PTS in chronic SDH include alcohol abuse, change in mental status, previous stroke, and hematoma density on CT.3 CT is the most widely used imaging modality for identifying ICH.

    Full Text Available Acute paraplegia is a rare but catastrophic complication of surgeries performed on aorta and corrective operations of vertebral column. Trauma to spinal cord after spinal anesthesia and ischemia of spinal cord also may lead to acute paraplegia. Acute paraplegia as a complication of general anesthesia in surgeries performed on sites other than aorta and vertebral column is very rare. Here we present a 56 year old woman with acute paraplegia due to spinal cord infarction after laparoscopic cholecystectomy under general anesthesia probably caused by atherosclerosis of feeding spinal arteries and ischemia of spinal cord after reduction of blood flow possibly due to hypotension during general anesthesia.

Objective: Exposing obstetric and perinatal outcomes of patients diagnosed with pancreatitis complicating pregnancy. A retrospective, observational, transverse and descriptive study; data were obtained and analyzed by reviewing medical records of patients diagnosed with pancreatitis and pregnancy. A total of 9 cases were included, corresponding to an incidence of 39/100,000 live births in the time period analyzed. The median age was 22, the mean gestational age at diagnosis was 31 weeks. 4 patients had cesarean delivery and 2 patients natural delivery. 3 patients had Ranson 3, a 2 and other Ranson Ranson 1 the remaining 4 Ranson 0. All products had adequate evolution. A case of maternal death as a complication of the disease was presented, because of metabolic acidosis and ARDS. Acute pancreatitis is an entity of variable incidence, which increases their appearance with advancing pregnancy, and can lead to serious complications for pregnant women. It is extremely important to pay attention to early symptoms of the disease, and achieve an accurate diagnosis and provide adequate multidisciplinary management for a better prognosis for maternal-fetal binomial.

    2015-01-05

    A 64-year-old man presented with a 2-day history of acute onset painless left ptosis. He had no other symptoms; importantly pupils were equal and reactive and eye movements were full. There was no palpable mass or swelling. He was systemically well with no headache, other focal neurological signs, or symptoms of fatigue. CT imaging showed swelling of the levator palpebrae superioris suggestive of myositis. After showing no improvement over 5 days the patient started oral prednisolone 30 mg reducing over 12 weeks. The ptosis resolved quickly and the patient remains symptom free at 6 months follow-up. Acute ptosis may indicate serious pathology. Differential diagnoses include a posterior communicating artery aneurysm causing a partial or complete third nerve palsy, Horner's syndrome, and myasthenia gravis. A careful history and examination must be taken. Orbital myositis typically involves the extraocular muscles causing pain and diplopia. Isolated levator myositis is rare. 2015 BMJ Publishing Group Ltd.

  16. Acute and Chronic Paronychia.

    Science.gov (United States)

    Leggit, Jeff C

    2017-07-01

    Paronychia is inflammation of the fingers or toes in one or more of the three nail folds. Acute paronychia is caused by polymicrobial infections after the protective nail barrier has been breached. Treatment consists of warm soaks with or without Burow solution or 1% acetic acid. Topical antibiotics should be used with or without topical steroids when simple soaks do not relieve the inflammation. The presence of an abscess should be determined, which mandates drainage. There are a variety of options for drainage, ranging from instrumentation with a hypodermic needle to a wide incision with a scalpel. Oral antibiotics are usually not needed if adequate drainage is achieved unless the patient is immunocompromised or a severe infection is present. Therapy is based on the most likely pathogens and local resistance patterns. Chronic paronychia is characterized by symptoms of at least six weeks' duration and represents an irritant dermatitis to the breached nail barrier. Common irritants include acids, alkalis, and other chemicals used by housekeepers, dishwashers, bartenders, florists, bakers, and swimmers. Treatment is aimed at stopping the source of irritation while treating the inflammation with topical steroids or calcineurin inhibitors. More aggressive techniques may be required to restore the protective nail barrier. Treatment may take weeks to months. Patient education is paramount to reduce the recurrence of acute and chronic paronychia.

  17. Acute decompensated pulmonary hypertension

    Directory of Open Access Journals (Sweden)

    2017-11-01

    Full Text Available Acute right heart failure in chronic precapillary pulmonary hypertension is characterised by a rapidly progressive syndrome with systemic congestion resulting from impaired right ventricular filling and/or reduced right ventricular flow output. This clinical picture results from an imbalance between the afterload imposed on the right ventricle and its adaptation capacity. Acute decompensated pulmonary hypertension is associated with a very poor prognosis in the short term. Despite its major impact on survival, its optimal management remains very challenging for specialised centres, without specific recommendations. Identification of trigger factors, optimisation of fluid volume and pharmacological support to improve right ventricular function and perfusion pressure are the main therapeutic areas to consider in order to improve clinical condition. At the same time, specific management of pulmonary hypertension according to the aetiology is mandatory to reduce right ventricular afterload. Over the past decade, the development of extracorporeal life support in refractory right heart failure combined with urgent transplantation has probably contributed to a significant improvement in survival for selected patients. However, there remains a considerable need for further research in this field.

    2003-11-01

    Syringomyelia is generally regarded as a chronic, slowly progressive disorder. We describe a case of acute dilation of the central canal of the spinal cord that presented with rapidly progressive segmental signs. A 29-year-old female patient who had previously undergone surgical treatment for a Chiari I malformation, syringomyelia, and hydrocephalus presented with an 8-day history of headaches, progressive paraparesis, and urinary retention. Magnetic resonance imaging scans demonstrated panventricular hydrocephalus in association with a holocord syrinx that extended to the obex. Magnetic resonance imaging scans that had been coincidentally obtained just 3 days before the onset of symptoms had revealed no evidence of hydrocephalus or syringomyelia. The patient underwent emergency revision of a failed ventriculoperitoneal shunt. Postoperatively, there was prompt resolution of the syringomyelia, hydrocephalus, and associated neurological deficits. Among patients with communicating syringomyelia, the central canal of the spinal cord participates as a "fifth ventricle" and can undergo rapid dilation in association with acute hydrocephalus. Appropriate treatment in such cases involves placement of a ventriculoperitoneal shunt.

    Pleural effusions and ascites are not uncommon in acute pancreatitis; however, pericardial effusions complicated by cardiac tamponade are extremely rare and definite treatment has yet to be established. This case report illustrates the findings in a 57-year-old patient, who was diagnosed of an acute alcoholic pancreatitis. The clinical course was complicated by recurrent episodes of acute pancreatitis, and eventually, the patient developed acute circulatory failure that was caused by cardiac tamponade. The patient was successfully treated by an emergency pericardiocentesis; however, although the patient was treated with intrapericardial triamcinolone and octreotide, pericardial effusion reoccurred. Eventually, a pancreaticopericardial fistula was diagnosed by endoscopic retrograde cholangiopancreaticography, and after successful stent placement in a disrupted pancreatic duct, the clinical recovery was uneventful. To the best of the authors' knowledge, this is the first case of a successful endoscopic treatment of a pancreaticopericardial fistula complicated by cardiac tamponade in a patient with acute pancreatitis.

    2011-01-01

    Leptospirosis is a globally important zoonotic disease and an important public health problem in developing countries. Early diagnosis is essential because antibiotic treatment is most effective when initiated early in the course of the disease. Culture and the microscopic agglutination test are gold standard methods for leptospirosis diagnosis; however, they are not useful for early diagnosis. Current whole cell-based rapid serological tests have low sensitivity for early phase leptospirosis and may have low specificity in highly endemic areas. PCR is demonstrably useful for early diagnosis, but it is unavailable in most developing countries. Thus, diagnostic methods that not only have higher sensitivity and accuracy for early phase leptospirosis but are also widely applicable in developing countries remain to be developed. The availability of genome sequences and genetic tools of Leptospira spp. will accelerate our understanding of Leptospira pathogenesis and provide insights into the development of more efficient and accurate diagnostic tests for acute-phase leptospirosis.

    This paper reports on sequential MR images and neurologic findings that were correlated in 40 acute spinal cord injuries. Within 1 week after injury, frequent initial MR changes appeared isointense on both T1- and T2-weighted images and isointense on T1- and hyperintense on T2-weighted images. After 2 months, hypointensity appeared on T1-weighted images and hyperintensity persisted or appeared on T2-weighted images. Clinical improvements were observed in patients with isointensity on both T1- and T2-weighted images at the initial examination. A larger area of hyperintensity on subsequent T2-weighted images was correlated with no neurologic improvement. MR findings were good indicators of the spinal cord injury

    2012-07-01

    Full Text Available Abstract Acute kidney injury (AKI is a serious complication in the perioperative period, and is consistently associated with increased rates of mortality and morbidity. Two major consensus definitions have been developed in the last decade that allow for easier comparison of trial evidence. Risk factors have been identified in both cardiac and general surgery and there is an evolving role for novel biomarkers. Despite this, there has been no real change in outcomes and the mainstay of treatment remains preventive with no clear evidence supporting any therapeutic intervention as yet. This review focuses on definition, risk factors, the emerging role of biomarkers and subsequent management of AKI in the perioperative period, taking into account new and emerging strategies.

    The concept of acute delirious puff refers to a transient psychotic state characterized by the sudden outbreak of a polymorphic delusional state in its themes and mecha- nisms. Magnan, in the late of nineteenth century, insti- gated the initial description of this concept. Rediscovered by Henri EY, it's current presence in the French psychiatry despite various attempts to dismantle it results from a singularity based on five cardinal points: it affects young adults, its onset is sudden, delusions are polymorphic and not systematic, there is a marked emotional lability and access is rapidly cured. This entity reveals vulnerability and must be understood carefully by the general practitioner, the issue being the prevention of progression to chronic psychosis.

    Full Text Available Case histories of 2 renal transplant recipients are reported who had presenting features of fever, leukocytosis and pain/tenderness over right iliac fossa and were diagnosed to be due to acute appendicitis rather than more commonly suspected acute rejection episode which has very similar features. Diagnosis of acute appendicitis was suspected on the basis of rectal examination and later confirmed by laparotomy. The purpose of this communication is to emphasize the need for proper diagnosis in patient with such presentation; otherwise wrong treatment may be received.

    The present article analyses the main presentations on acute pancreatitis at Digestive Disease Week 2015. Arterial pseudoaneurysm is an uncommon complication of acute pancreatitis (incidence 0.7%) and mortality from this cause is currently anecdotal. Diabetes mellitus has little impact on the clinical course of acute pancreatitis, unlike cirrhosis, which doubles the risk of mortality. Intake of unsaturated fat could be associated with an increased severity of acute pancreatitis and is a confounding factor in studies evaluating the relationship between obesity and morbidity and mortality. PET-CT (positron emission tomography-computed tomography) could be a non-invasive tool to detect infection of collections in acute pancreatitis. Peripancreatic fat necrosis is less frequent than pancreatic fat necrosis and is associated with a better clinical course. If the clinical course is poor, increasing the calibre of the percutaneous drains used in the treatment of infected necrosis can avoid surgery in 20% of patients. The use of low molecular-weight heparin in moderate or severe pancreatitis could be associated with a better clinical course, specifically with a lower incidence of necrosis. In acute recurrent pancreatitis, simvastatin is a promising drug for prophylaxis of new episodes of acute pancreatitis. Nutritional support through a nasogastric tube does not improve clinical course compared with oral nutrition. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    2015-06-01

    The care of patients with acutely decompensated heart failure is being reshaped by the availability and understanding of several novel and emerging heart failure biomarkers. The gold standard biomarkers in heart failure are B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide, which play an important role in the diagnosis, prognosis, and management of acute decompensated heart failure. Novel biomarkers that are increasingly involved in the processes of myocardial injury, neurohormonal activation, and ventricular remodeling are showing promise in improving diagnosis and prognosis among patients with acute decompensated heart failure. These include midregional proatrial natriuretic peptide, soluble ST2, galectin-3, highly-sensitive troponin, and midregional proadrenomedullin. There has also been an emergence of biomarkers for evaluation of acute decompensated heart failure that assist in the differential diagnosis of dyspnea, such as procalcitonin (for identification of acute pneumonia), as well as markers that predict complications of acute decompensated heart failure, such as renal injury markers. In this article, we will review the pathophysiology and usefulness of established and emerging biomarkers for the clinical diagnosis, prognosis, and management of acute decompensated heart failure.

  16. Acute Pulmonary Embolism Mimics Acute Coronary Syndrome in Older Patient

    Directory of Open Access Journals (Sweden)

    2009-12-01

    Full Text Available Acute pulmonary embolism is a fatal disease and an often missed diagnosis. There are no specific symptoms or signs. Accurate diagnosis followed by effective therapy can reduce mortality. We report on a 67-year-old man who underwent lumbar laminectomy and developed an acute anterior compressive-like chest pain and jaw numbness rather than dyspnea on the fifth postoperative day. Owing to refractory chest pain with suspicious posterior myocardial infarction or unstable angina on surface electrocardiogram, the patient received emergency coronary catheterization, which demonstrated normal coronary arteries. Further investigation provided a final diagnosis of acute pulmonary embolism. Acute pulmonary embolism with simultaneous recent neuro-surgery was a therapeutic dilemma because of the risk of postoperative hemorrhage threatening neurologic function. After treatment with enoxaparin and close monitoring of his neurologic condition, his symptoms were eliminated. Clinicians must keep in mind a differential diagnosis of pulmonary embolism in a postoperative high-risk patient.

    Acute abdomen is not a disease in itself but a description of a complex of symptoms combined with severe abdominal pain developed within a time frame of less than 24 h. All strategies for the management of acute abdomen underline the need for an interdisciplinary approach to diagnosis and therapy. This requires focused and intelligent use of efficient diagnostic procedures. Diagnostic laparoscopy may be a key to solving the diagnostic dilemma of unspecific acute abdomen. Furthermore, it allows not only direct inspection of the abdominal cavity but also surgical intervention, if needed. In particular the rate of negative laparotomies can be reduced.

    Acute pancreatitis is the most common gastro-intestinal indication for acute hospitalization and its incidence continues to rise. In severe pancreatitis, morbidity and mortality remains high and is mainly driven by organ failure and infectious complications. Early management strategies should aim to prevent or treat organ failure and to reduce infectious complications. This review addresses the management of acute pancreatitis in the first hours to days after onset of symptoms, including fluid therapy, nutrition and endoscopic retrograde cholangiography. This review also discusses the recently revised Atlanta classification which provides new uniform terminology, thereby facilitating communication regarding severity and complications of pancreatitis.

    Braess, Jan

    2016-11-01

    Acute myeloid leukemia (AML) has been genetically characterized extensively and can now be subdivided into 9 to 11 pathogenetically different subtypes according to their profile of driver mutations. In clinical practice karyotyping and molecular analysis of NPM1, cEBPa and FLT3-ITD are required for treatment stratification and potentially genotype specific treatment. Some markers such as NPM1 not only offer prognostic information but can also serve as markers of minimal residual disease and thus have the potential to guide therapy in the future.The basis of curative treatment is intensive combination chemotherapy comprizing cytarabine and an anthracycline ("7 + 3" regimen). The prolonged duration of aplasia can be reduced significantly by accelerated therapy ("S-HAM" regimen). Following achievement of a complete remission patients with a low risk of relapse - based on genetic and clinical features - receive chemotherapy based consolidation therapy whereas high risk patients - and potentially also those with an intermediate risk - receive an allogeneic stem cell transplantation. Whereas adding the rather unspecific tyrosinekinase inhibitor sorafenib to standard treatment in unselected AML patients has not improved overall survival (OS), the addition of midostaurin to standard therapy in the selected group FLT3 mutated patients has resulted in a moderate but significant OS benefit.Real world data show that in patients below 50 years a cure rate of ca. 50 % can be achieved. However less than 10 % of patients above the age of 70 will be alive after five years even after intensive treatment. Therefore when curative and intensive treatment is deemed impossible the therapeutic standard in elderly and unfit patients used to be low-dose cytarabine with an average OS of 4 months. This has now been replaced by a new standard of care of hypomethylating agents - azacytidine and decitabine - which both achieve higher remission rates and show strong trends towards a prolonged OS

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index 30 mmHg) and absent or reduced diuresis (acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Directory of Open Access Journals (Sweden)

    Marco Confalonieri

    2017-04-01

    Full Text Available Since its first description, the acute respiratory distress syndrome (ARDS has been acknowledged to be a major clinical problem in respiratory medicine. From July 2015 to July 2016 almost 300 indexed articles were published on ARDS. This review summarises only eight of them as an arbitrary overview of clinical relevance: definition and epidemiology, risk factors, prevention and treatment. A strict application of definition criteria is crucial, but the diverse resource-setting scenarios foster geographic variability and contrasting outcome data. A large international multicentre prospective cohort study including 50 countries across five continents reported that ARDS is underdiagnosed, and there is potential for improvement in its management. Furthermore, epidemiological data from low-income countries suggest that a revision of the current definition of ARDS is needed in order to improve its recognition and global clinical outcome. In addition to the well-known risk-factors for ARDS, exposure to high ozone levels and low vitamin D plasma concentrations were found to be predisposing circumstances. Drug-based preventive strategies remain a major challenge, since two recent trials on aspirin and statins failed to reduce the incidence in at-risk patients. A new disease-modifying therapy is awaited: some recent studies promised to improve the prognosis of ARDS, but mortality and disabling complications are still high in survivors in intensive care.

    Full Text Available This paper, based on relevant literature articles and the authors' clinical experience, presents a goal-oriented respiratory management for critically ill patients with acute respiratory distress syndrome (ARDS that can help improve clinicians' ability to care for these patients. Early recognition of ARDS modified risk factors and avoidance of aggravating factors during hospital stay such as nonprotective mechanical ventilation, multiple blood products transfusions, positive fluid balance, ventilator-associated pneumonia, and gastric aspiration can help decrease its incidence. An early extensive clinical, laboratory, and imaging evaluation of “at risk patients” allows a correct diagnosis of ARDS, assessment of comorbidities, and calculation of prognostic indices, so that a careful treatment can be planned. Rapid administration of antibiotics and resuscitative measures in case of sepsis and septic shock associated with protective ventilatory strategies and early short-term paralysis associated with differential ventilatory techniques (recruitment maneuvers with adequate positive end-expiratory pressure titration, prone position, and new extracorporeal membrane oxygenation techniques in severe ARDS can help improve its prognosis. Revaluation of ARDS patients on the third day of evolution (Sequential Organ Failure Assessment (SOFA, biomarkers and response to infection therapy allows changes in the initial treatment plans and can help decrease ARDS mortality.

    Sensory stimulation via acupuncture has been reported to alter activities of numerous neural systems by activating multiple efferent pathways. Acupuncture, one of the main physical therapies in Traditional Chinese Medicine, has been widely used to treat patients with stroke for over hundreds of years. This is the first update of the Cochrane Review originally published in 2005. To assess whether acupuncture could reduce the proportion of people with death or dependency, while improving quality of life, after acute ischemic or hemorrhagic stroke. We searched the Cochrane Stroke Group trials register (last searched on February 2, 2017), the Cochrane Central Register of Controlled Trials Ovid (CENTRAL Ovid; 2017, Issue 2) in the Cochrane Library, MEDLINE Ovid (1946 to February 2017), Embase Ovid (1974 to February 2017), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) EBSCO (1982 to February 2017), the Allied and Complementary Medicine Database (AMED; 1985 to February 2017), China Academic Journal Network Publishing Database (1998 to February 2017), and the VIP database (VIP Chinese Science Journal Evaluation Reports; 1989 to February 2017). We also identified relevant trials in the Chinese Clinical Trial Registry (last searched on Feburuary 20, 2017), the World Health Organization (WHO) International Clinical Trials Registry Platform (last searched on April 30, 2017), and Clinicaltrials.gov (last searched on April 30, 2017). In addition, we handsearched the reference lists of systematic reviews and relevant clinical trials. We sought randomized clinical trials (RCTs) of acupuncture started within 30 days from stroke onset compared with placebo or sham acupuncture or open control (no placebo) in people with acute ischemic or hemorrhagic stroke, or both. Needling into the skin was required for acupuncture. Comparisons were made versus (1) all controls (open control or sham acupuncture), and (2) sham acupuncture controls. Two review authors applied

    A 34-year-old woman with a diagnosis of hemophagocytic lymphohistocytosis (HLH) received a double umbilical cord blood transplantation following a myeloablative chemotherapy preparative regimen with busulfan and cyclophosphamide. HLH is a rare, potentially fatal hematologic disorder characterized by the overactivation of histocytes and T lymphocytes, leading to organ infiltration and acute illness. On day 25 post-transplantation, the patient required a platelet transfusion for a platelet count of 6,000 per ml (normal range = 150,000-450,000 per ml). The patient's blood type prior to the cord blood transplantation was B positive and, although both umbilical cord blood donors were O positive, the patient was still B positive per blood bank testing on that day. Although the recipient of an allogenic stem cell transplantation will eventually become the blood type of the donor, the time for this process to occur varies for each person. That process must be monitored by the blood bank for the purpose of cross-matching blood products to decrease hemolysis as much as possible. The patient was premedicated with the facility's standard for platelet transfusions: acetaminophen 650 mg and diphenhydramine 25 mg about 30 minutes prior to the platelet transfusion.

    Full Text Available In northeast Brazil, nutritional deficiency diseases and schistosomiasis mansoni overlap. An experimental model, wich reproduces the marasmatic clinical form of protein-energy malnutrition, was developed in this laboratory to study these interactions. Albino Swiss mice were fed with a food association ingested usually by human populations in northeast Brazil. This diet (Regional Basic Diet - RBD has negative effects on the growth, food intake and protein utilization in infected mice (acute phase of murine schistosomiasis. Nitrogen balance studies have also shown that infection with Schistosoma mansoni has apparently no effect on protein intestinal absorption in well nourished mice. However, the lowest absorption ratios have been detected among RBD - fed infected animals, suggesting that suprerimposed schistosome infection aggravated the nutritional status of the undernourished host. The serum proteins electrophoretic pattern, as far as albumins are concerned, is quite similar for non-infected undernourished and infected well-fed animals. So, the significance of albumins as a biochemical indicator of the nutritional status of human populations residing in endemic foci of Manson's schistosomiasis, is discussable.

    2016-01-01

    Full Text Available This review presents current data on the mechanism of action, selective toxicity, toxicokinetics and toxicodynamics of diacetylmorphine (heroin. Acute diacetylmorphine poisoning is considered under taking into account the developing a critical state, in which the poisoning severity is determined by severe metabolic disorders associated with the progression of hypoxia. The main lifethreatening complications of acute diacetyl morphine poisoning are described including those associated with the nervous system, respiratory, circulatory and urinary systems. Since hypoxia is the principal damaging factor, the the mechanisms of oxygen transport disorders and the pathogenesis of activation of free radical oxidation in acute diacetylmorphine poisoning are discussed. The improvement of intensive care strategy for severe forms of acute diacetylmorphine poisoning by the inclusion of a substrate antihypoxant Reamberin into the list of routine critical care prescriptions is emphesized.

    Blood glucose is often elevated in acute stroke, and higher admission glucose levels are associated with larger lesions, greater mortality and poorer functional outcome. In patients treated with thrombolysis, hyperglycemia is associated with an increased risk of hemorrhagic transformation...... to the risk of inducing potentially harmful hypoglycemia has been raised. Still, basic and observational research is overwhelmingly in support of a causal relationship between blood glucose and stroke outcome and further research on glucose-lowering therapy in acute stroke is highly warranted....

    Conclusions: Transfusion-related acute lung injury (TRALI and transfusion-associated circulatory overload (TACO are clinical syndromes with predominant pulmonary injury and respiratory distress. Anaphylactic reaction, hemolytic transfusion reaction and transfusion of contaminated blood products also impair lung function but are less frequent. Transfusion in critically ill and injured patient is an independent risk factor for acute lung injury. It remains to be determined whether transfusion is the cause of increased mortality or only an indicator of disease severity

    Central apnea, defined as cessation of breathing for ≥ 20 seconds, is frequent in premature infants born apnea in neonates. This paper explores the reported association between acute bilirubin encephalopathy and symptomatic apneic events in newborns and the possible mechanisms involved in the pathogenesis of this phenomenon. The prevalence of symptomatic apneic events in reports of acute bilirubin encephalopathy suggests this clinical finding should be considered a sign of bilirubin neurotoxicity. PMID:25239473

    Acute otitis media is a common childhood infection. Prompt diagnosis and appropriate treatment are very important. To review in depth the epidemiology, pathophysiology, clinical manifestations, diagnosis, complications and particularly treatment of acute otitis media in children. A PubMed search was completed in Clinical Queries using the key term "acute otitis media". Patents were searched using the key term "acute otitis media" from www.google.com/patents, http://espacenet.com, and www.freepatentsonline.com. Acute otitis media affects over 80% of children before their third birthday and 30 to 45% of these children have suffered two or more episodes. Streptococcus pneumoniae, nontypable Haemophilus influenzae, and Moraxella catarrhalis are the most frequently isolated middle-ear pathogens. The diagnosis is based on acute onset of symptoms such as otalgia and fever, middle ear inflammation such as erythema of the tympanic membrane, and middle ear effusion. The choice of treatment method depends on the age of the child, laterality, and the severity of the disease. Recent patents related to the management of acute otitis media are also retrieved and discussed. Antimicrobial treatment is recommended for all children less than two years of age, as well as in children ≥ two years of age who have a temperature ≥ 39oC; are toxic looking; have otalgia > 48 hours; have bilateral otitis media or otorrhea; have craniofacial abnormalities; are immunocompromised; or have uncertain access to follow-up. Amoxicillin is the drug of choice. Observation without antibiotic is an option in immunocompetent children ≥ two years of age who have an acute uncomplicated otitis media and non-severe illness if appropriate follow-up can be arranged.

    2006-01-01

    The aim of this study was to evaluate immune function in acute stress in medical students before academic examinations. Twenty-five medical students were selected because they presented intense acute stress, evaluated by the presence of the following classic signs: cold hands, intense sudoresis in the extremities, generalized sudoresis, paleness, tachycardia, confused reasoning, nervous irritability, diarrhea, and sleep disorders in the hours preceding the examination (agitated sleep, insomnia). Immediately before the examination, peripheral blood was collected from the 25 students presenting acute stress to analyze T and B cells, CD4+ and CD8+ cells, immunoglobulins, and C3 and C4 complement components, as well as phagocytic activity in neutrophils and monocytes. These investigations were repeated in the same students in situations free of acute stress. The results of the two samples collected from each student were compared. The means and standard deviations showed no significant differences for any of the parameters analyzed (p> or =0.01). We conclude that acute stress did not cause changes in the lymphocyte subpopulations, phagocytic activity of neutrophils and monocytes, serum immunoglobulins, or C3 and C4 complement components in students participating in the present study. In conditions of basal chronic stress, acute stress may cause alterations in immune function.

    Full Text Available To The Editor: Various pharmacological agents are used for the treatment of migraine. In the last five years, various drug companies in Bangladesh have been marketing pizotifen as a preventive treatment of all types of migraine. Pizotifen is a serotonin antagonist acting mainly at the 5-HT1, 5-HT2A and 5HT2C receptors. It also has some activity as an antihistamine (1. Pizotifen is a well-established preventative therapy of migraine. I would like to report my own experience in using pizotifen in treating the acute attacks of migraine. Pizotifen was prescribed as acute therapy in 11 patients, 6 females (4 had migraine without aura and 2 had migraine with aura and 5 males (all had migraine without aura. Three female and 5 male patients, who had migraine without aura, reported no beneficial effect of pizotifen as treatment for the acute attacks. Three female patients (two with migraine with aura and one with migraine without aura had their headache relieved by use of pizotifen as treatment for the acute attacks. This is an initial observation about the effectiveness of pizotifen as acute therapy in migraine. However, this could be simply a placebo affect. Nevertheless, it will be worth exploring the role of pizotifen as a therapeutic agent for acute attacks of migraine by conducting well-designed randomized, controlled studies.

    The aim of our study was to investigate the influence of metabolic syndrome on the course of acute pancreatitis determined by disease severity, the presence of local and systemic complications and survival rate. 609 patients admitted to our hospital in the period from January 1, 2008 up to June 31, 2015 with the diagnosis of acute pancreatitis were analyzed. The diagnosis and the severity of acute pancreatitis were made according to the revised Atlanta classification criteria from 2012. Of 609 patients with acute pancreatitis, 110 fulfilled the criteria for metabolic syndrome. Patients with metabolic syndrome had statistically significantly higher incidence of moderately severe (38.2% vs. 28.5%; p=0.05) and severe (22.7% vs. 12.8%; p=0.01) acute pancreatitis in comparison to those without metabolic syndrome, while patients without metabolic syndrome had higher incidence of mild acute pancreatitis in comparison to those patients with metabolic syndrome (58.7% vs. 39.1%; pacute pancreatitis. Comparing survival rates, patients suffering from metabolic syndrome had a higher death rate compared to patients without metabolic syndrome (16% vs. 4.5%; pacute pancreatitis, as well as higher mortality rate.

    Snyder, Matthew J; Bepko, Jennifer; White, Merima

    2014-04-01

    Acute pericarditis, inflammation of the pericardium, is found in approximately 5% of patients admitted to the emergency department for chest pain unrelated to acute myocardial infarction. It occurs most often in men 20 to 50 years of age. Acute pericarditis has a number of potential etiologies including infection, acute myocardial infarction, medication use, trauma to the thoracic cavity, and systemic diseases, such as rheumatoid arthritis. However, most etiologic evaluations are inconclusive. Patients with acute pericarditis commonly present with acute, sharp, retrosternal chest pain that is relieved by sitting or leaning forward. A pericardial friction rub is found in up to 85% of patients. Classic electrocardiographic changes include widespread concave upward ST-segment elevation without reciprocal T-wave inversions or Q waves. First-line treatment includes nonsteroidal anti-inflammatory drugs and colchicine. Glucocorticoids are traditionally reserved for severe or refractory cases, or in cases when the cause of pericarditis is likely connective tissue disease, autoreactivity, or uremia. Cardiology consultation is recommended for patients with severe disease, those with pericarditis refractory to empiric treatment, and those with unclear etiologies.

    The outcome of childhood acute lymphoblastic leukemia has improved because of intensive chemotherapy and supportive care. The frequency of adverse events has also increased, but the data related to acute central nervous system complications during acute lymphoblastic leukemia treatment are sparse. The purpose of this study is to evaluate these complications and to determine their long term outcome. We retrospectively analyzed the hospital reports of 323 children with de novo acute lymphoblastic leukemia from a 13-year period for acute neurological complications. The central nervous system complications of leukemic involvement, peripheral neuropathy, and post-treatment late-onset encephalopathy, and neurocognitive defects were excluded. Twenty-three of 323 children (7.1%) suffered from central nervous system complications during acute lymphoblastic leukemia treatment. The majority of these complications (n = 13/23; 56.5%) developed during the induction period. The complications included posterior reversible encephalopathy (n = 6), fungal abscess (n = 5), cerebrovascular lesions (n = 5), syndrome of inappropriate secretion of antidiuretic hormone (n = 4), and methotrexate encephalopathy (n = 3). Three of these 23 children (13%) died of central nervous system complications, one from an intracranial fungal abscess and the others from intracranial thrombosis. Seven of the survivors (n = 7/20; 35%) became epileptic and three of them had also developed mental and motor retardation. Acute central neurological complications are varied and require an urgent approach for proper diagnosis and treatment. Collaboration among the hematologist, radiologist, neurologist, microbiologist, and neurosurgeon is essential to prevent fatal outcome and serious morbidity. Copyright © 2015 Elsevier Inc.

    It is often difficult to differentiate acute pancreatitis (A.P.) from some other acute abdominal diseases, when there is an elevated serum amylase. In contrast, the renal clearance of amylase, expressed as a percentage of creatinine clearance, can separate patients with A.P. from patients with acute colecistitis, common duct stone without pancreatitis, hyperamylasemia after biliary surgery, acute peptic ulcer and acute salivary diseases.

    Full Text Available Objective: to evaluate the efficiency of methods for diagnosing and treating critically ill patients with acute respiratory failure (ARF in acute poisoning by neurotropic substances. Subjects and methods. Two hundred and thirty-three patients with acute severe intoxication with neurotropic poisons were examined. All the patients were admitted for toxic-hypoxic coma and ARF; in this connection all the patients underwent artificial ventilation (AV. The patients were divided into 3 groups: 1 those in whom the traditional treatments (AV, detoxifying therapy, and infusional and cardiotropic support could restore the basic parameters of vital functions, as judged from the recovered oxygenation index; these patients had no metabolic shifts; 2 those who had signs of pulmonary hyperhydration, low cardiac output and moderate metabolic disorders, as suggested by elevated lactate levels; 3 seriously ill patients in whom the interval between the time of poisoning to care delivery was more than 20 hours; the patients of this group had the most significant metabolic disorders. Results. Correction of ARF in critically ill patients with acute poisoning should include, in addition to the rational parameters of AV and detoxifying therapy, agents for targeted therapy for sequels of hypoxia and energy deficiency states. For maximally rapid and effective oxygen transport recovery, the addition of perfluorane to the complex therapy cardinally improves the results of treatment and reduces mortality rates. Conclusion. The complexity of the pathogenesis of ARF and its sequels is a ground for diagnosing and correcting not only ventilation disturbances, but also pulmonary microcirculatory disorders and metabolic disturbances. Key words: acute intoxication with neu-rotropic poisons, acute respiratory failure, pulmonary hyperhydration, hypoxia, metabolic disturbances.

    2015-09-01

    This session of the Society for Hematopathology/European Association for Haematopathology Workshop focused on acute leukemias of ambiguous origin. We provide an overview of mixed-phenotype acute leukemia (MPAL) as recognized in the current World Health Organization classification and summarize diagnostic criteria for major categories of MPAL: B/myeloid, T/myeloid, B/T, and B/T/myeloid. Most MPAL cases submitted were B/myeloid and T/myeloid MPAL, the most frequent types, but three cases of B/T MPAL were also submitted, and examples of all categories are illustrated. We emphasize that a comprehensive approach to immunophenotyping is required to accurately establish the diagnosis of MPAL. Flow cytometry immunophenotyping using a large panel of antibodies is needed as well as confirmatory immunohistochemical analysis and cytochemistry studies for myeloperoxidase and nonspecific esterase. We discuss technical issues in determining blast lineage and possible pitfalls in MPAL diagnosis. In particular, rare cases of B-acute lymphoblastic leukemia (B-ALL) can express myeloperoxidase but are otherwise consistent with B-ALL and should be treated as such. Last, we review the differential diagnosis between acute undifferentiated leukemia and acute myeloid leukemia with minimal differentiation. There was an agreement that diagnosis of MPAL can be challenging, especially if applied flow cytometry panels are not comprehensive enough. Copyright© by the American Society for Clinical Pathology.

    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. Published by Elsevier Inc.

    2014-02-01

    Laparoscopy has become a routine procedure in the management of acute abdominal disease and can be considered both an excellent therapeutic and additional diagnostic tool in selected cases. However, a high level of expertise in laparoscopic and emergency surgery is required. Hemodynamic instability, huge abdominal distension, fecal peritonitis and perforated cancer are relative contraindications for the laparoscopic approach. In recent years, abdominal emergencies have increasingly been managed successfully by laparoscopy. In acute appendicitis, acute cholecystitis and perforated peptic ulcer, randomized controlled trials have proven that the laparoscopic approach is as safe and as effective as open surgery, with fewer complications and a quicker postoperative recovery. Other indications such as blunt and penetrating trauma to the abdomen, small bowel occlusion and perforated diverticular disease are under debate, indicating that more randomized controlled trials comparing laparoscopic and open surgery are still necessary.

    The recent “Advanced Neuroimaging for Acute Stroke Treatment” meeting on September 7 and 8, 2007 in Washington DC, brought together stroke neurologists, neuroradiologists, emergency physicians, neuroimaging research scientists, members of the National Institute of Neurological Disorders and Stroke (NINDS), the National Institute of Biomedical Imaging and Bioengineering (NIBIB), industry representatives, and members of the US Food and Drug Administration (FDA) to discuss the role of advanced neuroimaging in acute stroke treatment. The goals of the meeting were to assess state-of-the-art practice in terms of acute stroke imaging research and to propose specific recommendations regarding: (1) the standardization of perfusion and penumbral imaging techniques, (2) the validation of the accuracy and clinical utility of imaging markers of the ischemic penumbra, (3) the validation of imaging biomarkers relevant to clinical outcomes, and (4) the creation of a central repository to achieve these goals. The present article summarizes these recommendations and examines practical steps to achieve them. PMID:18477656

    2013-09-01

    Racecadotril has sufficient proven efficacy in the treatment of acute diarrhea in children. Treatment outcomes in adults are less convincing. The place of gelatin tannate is unclear. Some sources point to potential hepatotoxicity and diminished iron absorption, with a concomitant risk of anemia, at least in case of excessive or prolonged use. Loperamide still has a prominent place in the treatment of acute and chronic diarrhea. Attention should be payed to correct dosing and some well-known contra-indications. Probiotics are indicated in children, as well as in the prevention of antibiotics-induced diarrhea. There is no evidence to support their use in the treatment of acute diarrhea in adults. Up till now publications disagree on the efficacy in the prevention of travelers' diarrhea. Astringents and absorbents are no longer supported in guidelines. Oral rehydration systems have a part to play in pediatric treatment.

    INTRODUCTION: Acute bronchitis is a self-limiting infectious disease characterized by acute cough with or without sputum but without signs of pneumonia. About 90% of cases are caused by viruses. AREAS COVERED: Antibiotics for acute bronchitis have been associated with an approximately half......-day reduction in duration of cough. However, at follow-up there are no significant differences in overall clinical improvement inpatients treated with antibiotics compared with those receiving placebo. Despite this, antibiotics are administered to approximately two thirds of these patients. This review...... discusses the reason for this antibiotic overprescription. Other therapies targeted to control symptoms have also demonstrated a marginal or no effect. EXPERT COMMENTARY: Clinicians should be aware of the marginal effectiveness of antibiotic therapy. Some strategies like the use of rapid tests, delayed...

    Subarachnoid hemorrhage was produced in four Macaca nemestrina monkeys using the technique of Frazee. CT and MR imaging was performed immediately after the procedure and at frequent intervals up to 2 weeks after hemorrhage. The imaging studies were compared with clinical evaluations and pathologic specimens of all animals. Additional human clinical CT/MR studies of subarachnoid hemorrhage were also studied. Acute hemorrhage was recognized on MR images as an increase in signal in the region of clot compared with surrounding cerebrospinal fluid. This most likely reflects T1 shortening due to proton binding rather than a pure paramagnetic effect. While CT is sensitive to the hemoglobin protein in acute hemorrhage, the superior resolution of MR of the basal cisterns results in equal or better definition of acute subarachnoid hemorrhage on MR studies in many cases

    Full text: Introduction: Computed Tomography (CT) is the imaging modality of choice for the diagnosis and staging of acute pancreatitis and its complications. Objectives and tasks: The purpose of this presentation is to demonstrate the findings in CT images which are useful for staging acute pancreatitis according to Balthazar, their significance and restrictions. Materials and methods: CT images from patients who were referred to our Department for an abdominal CT scan for the diagnosis or/and staging of acute pancreatitis were retrospectively studied. Results: In acute pancreatitis, CT helps to stage the severity of inflammatory process, to detect pancreatic necrosis and to depict local complications. CT severity index (CTSI), which was proposed by Balthazar et al, combines the grade of pancreatitis with the extent of pancreatic necrosis assigning points to the patients in order to find the severity index which scales from 0-10. More points are given for a higher grade of pancreatitis and for more extensive necrosis. Types of pancreatitis according to CTSI are: interstitial (Balthazar grade A-C), exudative (Balthazar grade D or E), necrotising (Balthazar grade E, CTSI:10) and central gland necrotising. Patients with pancreatitis but no collections or necrosis have an interstitial (mild) pancreatitis. In exudative pancreatitis there is normal enhancement of the entire pancreas associated with extensive peripancreatic collections. Necrotizing (severe) pancreatitis is characterized by protacted clinical course, high incidence of local complications and high mortality rate. Central gland necrosis is a subtype of necrotizing pancreatitis. Conclusions: The combination of CT imaging and clinical and laboratory evaluation allows the early diagnosis of acute pancreatitis. Acute pancreatitis may vary from a mild uneventful disease to a severe life-threatening illness with multisystemic organ failure. Thus, it is crucial to identify patients who are at high risk of severe

    Full Text Available Abstract Acute graft-versus-host disease (GVHD occurs after allogeneic hematopoietic stem cell transplant and is a reaction of donor immune cells against host tissues. Activated donor T cells damage host epithelial cells after an inflammatory cascade that begins with the preparative regimen. About 35%–50% of hematopoietic stem cell transplant (HSCT recipients will develop acute GVHD. The exact risk is dependent on the stem cell source, age of the patient, conditioning, and GVHD prophylaxis used. Given the number of transplants performed, we can expect about 5500 patients/year to develop acute GVHD. Patients can have involvement of three organs: skin (rash/dermatitis, liver (hepatitis/jaundice, and gastrointestinal tract (abdominal pain/diarrhea. One or more organs may be involved. GVHD is a clinical diagnosis that may be supported with appropriate biopsies. The reason to pursue a tissue biopsy is to help differentiate from other diagnoses which may mimic GVHD, such as viral infection (hepatitis, colitis or drug reaction (causing skin rash. Acute GVHD is staged and graded (grade 0-IV by the number and extent of organ involvement. Patients with grade III/IV acute GVHD tend to have a poor outcome. Generally the patient is treated by optimizing their immunosuppression and adding methylprednisolone. About 50% of patients will have a solid response to methylprednisolone. If patients progress after 3 days or are not improved after 7 days, they will get salvage (second-line immunosuppressive therapy for which there is currently no standard-of-care. Well-organized clinical trials are imperative to better define second-line therapies for this disease. Additional management issues are attention to wound infections in skin GVHD and fluid/nutrition management in gastrointestinal GVHD. About 50% of patients with acute GVHD will eventually have manifestations of chronic GVHD.

  6. Treatment of acute viral bronchiolitis.

    Acute viral bronchiolitis represents the most common lower respiratory tract infection in infants and young children and is associated with substantial morbidity and mortality. Respiratory syncytial virus is the most frequently identified virus, but many other viruses may also cause acute bronchiolitis. There is no common definition of acute viral bronchiolitis used internationally, and this may explain part of the confusion in the literature. Most children with bronchiolitis have a self limiting mild disease and can be safely managed at home with careful attention to feeding and respiratory status. Criteria for referral and admission vary between hospitals as do clinical practice in the management of acute viral bronchiolitis, and there is confusion and lack of evidence over the best treatment for this condition. Supportive care, including administration of oxygen and fluids, is the cornerstone of current treatment. The majority of infants and children with bronchiolitis do not require specific measures. Bronchodilators should not be routinely used in the management of acute viral bronchiolitis, but may be effective in some patients. Most of the commonly used management modalities have not been shown to have a clear beneficial effect on the course of the disease. For example, inhaled and systemic corticosteroids, leukotriene receptor antagonists, immunoglobulins and monoclonal antibodies, antibiotics, antiviral therapy, and chest physiotherapy should not be used routinely in the management of bronchiolitis. The potential effect of hypertonic saline on the course of the acute disease is promising, but further studies are required. In critically ill children with bronchiolitis, today there is little justification for the use of surfactant and heliox. Nasal continuous positive airway pressure may be beneficial in children with severe bronchiolitis but a large trial is needed to determine its value. Finally, very little is known on the effect of the various

    Pancreatitis in pregnancy remains a rare event and is most often associated with gallstone disease. Hyperlipidemic gestational pancreatitis usually occurs in women with a preexisting abnormality of the lipid metabolism and poses particular problems in diagnosis and clinical management. We describe 5 patients with acute episodes of pancreatitis during pregnancy caused by hyperlipidemia. Acute pancreatitis in pregnancy causes significant morbidity. Even though it is often associated with gallstones, we describe 5 cases in which the etiology of the pancreatitis was maternal hyperlipidemia. Etiology, diagnosis, and management will be discussed.

    The 'rim sign' is a rim of increased hepatic activity adjacent to the gall bladder fossa and known as an useful indicator of acute cholecystitis. Also, many reports suggested that if rim sign is positive there is an increased risk for complications such as perforation and gangrene. To evaluate the usefulness of this rim sign, we reviewed 32 cases that were pathologically confirmed. The incidence of rim sign was 47% similar to other reports but with our results, the rim sign was not specific to acute cholecystitis nor indicator of increased risk for complications.

    Seventy nine elderly patients with acute abdominal conditions were operated on in the Emergency Service of the Hospital das Clinicas of the University of São Paulo from 1981 to 1985. Total mortality rate was 58.23%. In patients with acute vascular abdominal conditions it was 100%, in inflammatory conditions 55.17% and in intestinal obstruction 47.83%. The lowest mortality was observed in traumatic conditions (27.27%). Procrastination of operations was followed by higher mortality. In operations lasting more than three hours the mortality was significantly higher than in those lasting less than three hours. Associated diseases as well as reoperations increased the postoperative mortality.

    We report a case of amoebic appendicitis without colitis symptoms. Acute appendicitis is commonly encountered by gastroenterologists in their daily practice. The number of cases of amoebiasis increases annually in Japan, and is thought to be associated with an increase in sexually transmitted disease or travel to endemic areas. However, acute amoebic appendicitis is rare and the prognosis is very poor compared to nonamoebic appendicitis. In our case, appendectomy was performed immediately after onset, and the patient was discharged without complications. It is difficult to differentiate between amoebic and nonamoebic appendicitis preoperatively, and the possibility of amoebic appendicitis should be kept in mind.

  13. MicroRNA profiling can classify acute leukemias of ambiguous lineage as either acute myeloid leukemia or acute lymphoid leukemia.

    Classification of acute leukemia is based on the commitment of leukemic cells to the myeloid or the lymphoid lineage. However, a small percentage of acute leukemia cases lack straightforward immunophenotypical lineage commitment. These leukemias of ambiguous lineage represent a heterogeneous category of acute leukemia that cannot be classified as either acute myeloid leukemia (AML) or acute lymphoid leukemia (ALL). The lack of clear classification of acute leukemias of ambiguous lineage as either AML or ALL is a hurdle in treatment choice for these patients. Here, we compared the microRNA (miRNA) expression profiles of 17 cases with acute leukemia of ambiguous lineage and 16 cases of AML, B-cell acute lymphoid leukemia (B-ALL), and T-cell acute lymphoid leukemia (T-ALL). We show that leukemias of ambiguous lineage do not segregate as a separate entity but exhibit miRNA expression profiles similar to AML, B-ALL, or T-ALL. We show that by using only 5 of the most lineage-discriminative miRNAs, we are able to define acute leukemia of ambiguous lineage as either AML or ALL. Our results indicate the presence of a myeloid or lymphoid lineage-specific genotype, as reflected by miRNA expression, in these acute leukemias despite their ambiguous immunophenotype. miRNA-based classification of acute leukemia of ambiguous lineage might be of additional value in therapeutic decision making.

    2010-08-28

    Acute pancreatitis is characterized by acute chemical injury of the pancreatic parenchyma and peripancreatic tissue. The increased frequency of death in acute pancreatitis is directly correlated with the degree and progress of pancreatic necrosis. Moreover, the occurrence of some local complications in acute pancreatitis, such as pancreatic hemorrhage, peripancreatic abscess or large pseudocyst, and pseudoaneurysm, could influence the choice of treatment for these patients. Magnetic resonance imaging (MRI) can be used to help evaluate the presence and degree of pancreatic necrosis, and is crucial for identifying complications of acute pancreatitis and predicting prognosis. The purpose of this article is to describe MRI techniques for acute pancreatitis, to review the spectrum of pancreatic and peripancreatic patterns, as well as to survey various complications secondary to acute pancreatitis on MRI. The role of MRI in the initial evaluation and staging of acute pancreatitis is emphasized.

    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. Thieme Medical Publishers.

  1. Redox signaling in acute pancreatitis

    Science.gov (United States)

    Pérez, Salvador; Pereda, Javier; Sabater, Luis; Sastre, Juan

    2015-01-01

    Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On the other hand, the release of extracellular hemoglobin into the circulation from the ascitic fluid in severe necrotizing pancreatitis enhances lipid peroxidation in plasma and the inflammatory infiltrate into the lung and up-regulates the HIF–VEGF pathway, contributing to the systemic inflammatory response. Therefore, redox signaling and oxidative stress contribute to the local and systemic inflammatory response during acute pancreatitis. PMID:25778551

    While conservative management such as fluid, bowel rest, and antibiotics is the mainstay of current acute pancreatitis management, there is a lot of promise in pharmacologic therapies that target various aspects of the pathogenesis of pancreatitis. Extensive review of preclinical studies, which include assessment of therapies such as anti-secretory agents, protease inhibitors, anti-inflammatory agents, and anti-oxidants are discussed. Many of these studies have shown therapeutic benefit and improved survival in experimental models. Based on available preclinical studies, we discuss potential novel targeted pharmacologic approaches that may offer promise in the treatment of acute pancreatitis. To date a variety of clinical studies have assessed the translational potential of animal model effective experimental therapies and have shown either failure or mixed results in human studies. Despite these discouraging clinical studies, there is a great clinical need and there exist several preclinical effective therapies that await investigation in patients. Better understanding of acute pancreatitis pathophysiology and lessons learned from past clinical studies are likely to offer a great foundation upon which to expand future therapies in acute pancreatitis.

    Hypercalcaemia due to primary hyperparathyroidism is a rare cause of acute pancreatitis, with a reported prevalence of 1.5 to 8%. There is no clear pathophysiological basis, but elevated parathyroid hormone and high serum calcium levels could be responsible for calcium deposit in the pancreatic ducts and activation of pancreatic enzymes, which may be the main risk factor for developing acute pancreatitis. The aim of this report is to describe four cases. Four cases are reported of severe pancreatitis associated with hypercalcaemia secondary to primary hyperparathyroidism; three of them with complications (two pseudocysts and one pancreatic necrosis). Cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, studies showed the parathyroid adenoma. Surgical resection was the definitive treatment in all four cases. None of the patients had recurrent acute pancreatitis events during follow-up. Acute pancreatitis secondary to hypercalcaemia of primary hyperparathyroidism is rare; however, when it occurs it is associated with severe pancreatitis. It is suspected in patients with elevated serum calcium and high parathyroid hormone levels. Imaging techniques such as cervical ultrasound, computed tomography, and scintigraphy using 99mTc-Sestambi, should be performed, to confirm clinical suspicion. Surgical resection is the definitive treatment with excellent results. Copyright © 2015 Academia Mexicana de Cirugía A.C. Published by Masson Doyma México S.A. All rights reserved.

  8. Acute muscular weakness in children

    Ricardo Pablo Javier Erazo Torricelli

    Full Text Available ABSTRACT Acute muscle weakness in children is a pediatric emergency. During the diagnostic approach, it is crucial to obtain a detailed case history, including: onset of weakness, history of associated febrile states, ingestion of toxic substances/toxins, immunizations, and family history. Neurological examination must be meticulous as well. In this review, we describe the most common diseases related to acute muscle weakness, grouped into the site of origin (from the upper motor neuron to the motor unit. Early detection of hyperCKemia may lead to a myositis diagnosis, and hypokalemia points to the diagnosis of periodic paralysis. Ophthalmoparesis, ptosis and bulbar signs are suggestive of myasthenia gravis or botulism. Distal weakness and hyporeflexia are clinical features of Guillain-Barré syndrome, the most frequent cause of acute muscle weakness. If all studies are normal, a psychogenic cause should be considered. Finding the etiology of acute muscle weakness is essential to execute treatment in a timely manner, improving the prognosis of affected children.

    Full Text Available Acute leukemia in early childhood is biologically and clinically distinct. The particular characteristics of this malignancy diagnosed during the first months of life have provided remarkable insights into the etiology of the disease. The pro-B, CD10 negative immunophenotype is typically found in infant acute leukemia, and the most common genetic alterations are the rearrangements of the MLL gene. In addition, the TEL/AML1 fusion gene is most frequently found in children older than 24 months. A molecular study on a Brazilian cohort (age range 0-23 months has detected TEL/AML1+ve (N = 9, E2A/PBX1+ve (N = 4, PML/RARA+ve (N = 4, and AML1/ETO+ve (N = 2 cases. Undoubtedly, the great majority of genetic events occurring in these patients arise prenatally. The environmental exposure to damaging agents that give rise to genetic changes prenatally may be accurately determined in infants since the window of exposure is limited and known. Several studies have shown maternal exposures that may give rise to leukemogenic changes. The Brazilian Collaborative Study Group of Infant Acute Leukemia has found that mothers exposed to dipyrone, pesticides and hormones had an increased chance to give birth to babies with infant acute leukemia [OR = 1.48 (95%CI = 1.05-2.07, OR = 2.27 (95%CI = 1.56-3.31 and OR = 9.08 (95%CI = 2.95-27.96], respectively. This review aims to summarize recent clues that have facilitated the elucidation of the biology of early childhood leukemias, with emphasis on infant acute leukemia in the Brazilian population.

    Full Text Available Acute pancreatitis is an acute inflammatory process of the pancreas with variable involvement of other regional tissues or other organ systems. The severe form of the disease occurs in 10-20% of cases, and usually requires prolonged hospitalization due to a frequent local and systemic complications. Additionally, considerable mortality despite diagnostic and therapeutic advances, makes this disease a serious health problem nowadays. The aim of this study was to conduct a review of randomized controlled trials to determine differences in the efficiency between standard methods of treatment for severe acute pancreatitis and new treatment ways in terms of decreased mortality. Search of the 'Medline' database of original scientific papers and systematic review articles was made, using a combination of the following keywords: acute pancreatitis, treatment, mortality. In total 914 papers were found, published in the last 13 years; 14 of 64 randomized controlled clinical trials met the selection criteria and were eligible for inclusion. From a total of 16 papers, the conservative treatment was related to 11, which includes some of the new treatment methods, while the effects of new methods of treatment have been the subject of research in the four studies. Combined endoscopic and surgical treatment was applied in only one study. The largest sample of 290 patients was included in the study with platelet activation factor antagonist, while the smallest sample of 22 patients was used in the study that compared total parenteral with enteral nutrition. Continuous regional arterial infusion of protease inhibitors in combination with antibiotics, intravenous supplementation of alanyl-glutamine dipeptide and the early, high-volume continuous veno-venous hemofiltration showed the best results in the treatment of patients with severe acute pancreatitis. Also, the use of low molecular weight heparin and enteral nutrition significantly reduced mortality.

    2007-01-01

    There are now powerful compensatory therapies to counteract kidney deficiency and the prognosis of patients with acute renal failure is mainly related to the severity of the initial disease. Renal failure is accompanied by an increase in both severity and duration of the catabolic phase leading to stronger catabolic consequences. The specificity of the metabolic and nutritional disorders in the most severely ill patients is the consequence of three additive phenomena: (1) the metabolic response to stress and to organ dysfunction, (2) the lack of normal kidney function and (3) the interference with the renal treatment (hemodialysis, hemofiltration or both, continuous or intermittent, lactate or bicarbonate buffer, etc.). As in many other diseases of similar severity, adequate nutritional support in acutely ill patients with ARF is of great interest in clinical practice, although the real improvement as a result of this support is still difficult to assess in terms of morbidity or mortality.

    Acute respiratory distress syndrome (ARDS) is a severe respiratory condition that is characterized by rapidly progressive hypoxemia with noncardiogenic pulmonary edema. Despite the improvement of therapeutic methods, the mortality of ARDS is in the range of 40%-50% all over the world. Some studies have shown that a significant number of patients with ARDS had acute cor pulmonale (ACP), and ACP is independently associated with the mortality of patients with ARDS, which has attracted wide attention in recent years. This paper reviewed recent related studies, summarized the prevalence, pathogenesis and diagnostic approaches of ACP in ARDS, especially echocardiography which was considered as a cornerstone for ACP diagnosis, and elucidated the beneficial effects of right ventricular protective ventilatory strategy and prone-positioning on the pulmonary vasculature and right heart, in order to provide a novel idea for the therapy of ACP in ARDS.

    Acute appendicitis and acute cholecystitis are among the most common diagnoses that general surgeons operate on. However, it is rarely described in its synchronous form. A 43 year-old woman attending the clinic for right upper quadrant pain of 11 days duration. The patient refers to intermittent radiating pain in the right side, with positive Murphy, tachycardia, and fever. The laboratory results showed white cells 16,200/mm(3), glucose 345 mg/dl, abnormal liver function tests. Acute cholecystitis was reported with ultrasound. A Masson-type incision was made, noting an enlarged pyogenic gallbladder with thickened walls, sub-hepatic abscess of approximately 300 ml, greenish-yellow colour, and foetid. An anterograde subtotal cholecystectomy is performed due to difficulty in identifying elements of Calot triangle due to the inflammatory process, opening it and extracting stones. The right iliac fossa is reviewed, finding a plastron and a sub-serous retrocaecal appendix perforated in its middle third with free fecalith and an abscess in the pelvic cavity. An anterograde appendectomy was performed and the patient progressed satisfactorily, later being discharged due to improvement. In this patient, with a history of recurrent episodes of gallbladder pain and disseminated acute abdominal pain without peritoneal irritation, clinical suspicion was exacerbated cholecystitis with probable empyema of the gallbladder. Open surgery approach for this patient allowed access to both the appendix and gallbladder in order to perform a complete exploration of the abdominal cavity. The synchronous presentation of cholecystolithiasis and complicated appendicitis has not been reported in the literature. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    2010-04-01

    Urinary tract infection (UTI) may predominantly involve the lower urinary tract, i.e. acute cystitis, or upper urinary tract consisting of the renal pelvis and kidney,, i.e. acute pyelonephritis The incidence of acute pyelonephritis is higher in young women than in men but the incidence in men over 65 is similar to that in older women. Women have up to a 10% risk of recurrent acute pyelonephritis in the year following a first acute episode. The equivalent risk in men is 6%. Acute pyelonephritis may be uncomplicated and resolve without serious sequelae. A minority of episodes may be complicated by acute kidney injury, papillary necrosis, renal or perinephric abscess or the development of emphysematous pyelonephritis. Acute pyelonephritis is generally caused by microorganisms ascending from the urethra via the bladder into the upper urinary tract. Rarely the kidney may be seeded by blood-borne infection. Ecoli is the most common uropathogen causing pyelonephritis accounting for 70-90% of infections. Species of Enterococci, Klebsiella, Pseudomonas, Proteus and Staphylococci are responsible for the remaining infections. There is a rising incidence in the community of UTI with bacteria that produce extended spectrum beta-lactamase (ESBL) enzymes. These ESBL bacteria have developed resistance to antibiotics such as penicillin, cephalosporins and increasingly to quinolones. Risk factors for uncomplicated acute pyelonephritis include recent sexual intercourse, acute cystitis, stress incontinence and diabetes and for complicated acute pyelonephritis include pregnancy, diabetes, anatomical abnormalities of the urinary tract and renal calculi.

  12. Nonacetaminophen Drug-Induced Acute Liver Failure.

    2018-05-01

    Acute liver failure of all causes is diagnosed in between 2000 and 2500 patients annually in the United States. Drug-induced acute liver failure is the leading cause of acute liver failure, accounting for more than 50% of cases. Nonacetaminophen drug injury represents 11% of all cases in the latest registry from the US Acute Liver Failure Study Group. Although rare, acute liver failure is clinically dramatic when it occurs, and requires a multidisciplinary approach to management. In contrast with acetaminophen-induced acute liver failure, non-acetaminophen-induced acute liver failure has a more ominous prognosis with a lower liver transplant-free survival.

    Acute renal failure (ARF) may be due to obstructive uropathy or renal parenchymal disease. Twenty-five children with acute renal failure secondary to renal parenchymal disease underwent ultrasonographic examination of the kidneys. Changes of renal size and cortical echogenicity were correlated with renal function. All patients presented with bilaterally enlarged kidneys with the exception in renal function resulted in normalization of renal size. With regard to cortical echogenicity two groups were formed. Group A comprised 11 patients whose kidneys had the same echogenicity as the liver, while in group B the kidneys were more echogenic (14 patients). Cortical echogenicity was always increased. Determination of creatinine levels showed a statistically significant difference between group A (3.32 mg% ± 1.40 S.D.) and group B (5.95 mg% ± 1.96 S.D.), p < 0.001. Changes in renal function were paralleled by rapid changes in renal size and cortical echogenicity. (orig.)

    Full Text Available At any point 1–5 days following ascent to altitudes ≥2500 m, individuals are at risk of developing one of three forms of acute altitude illness: acute mountain sickness, a syndrome of nonspecific symptoms including headache, lassitude, dizziness and nausea; high-altitude cerebral oedema, a potentially fatal illness characterised by ataxia, decreased consciousness and characteristic changes on magnetic resonance imaging; and high-altitude pulmonary oedema, a noncardiogenic form of pulmonary oedema resulting from excessive hypoxic pulmonary vasoconstriction which can be fatal if not recognised and treated promptly. This review provides detailed information about each of these important clinical entities. After reviewing the clinical features, epidemiology and current understanding of the pathophysiology of each disorder, we describe the current pharmacological and nonpharmacological approaches to the prevention and treatment of these diseases.

    Full Text Available Acute hemorrhagic edema of infancy is a rare form of leukocytoclastic vasculitis. Mostly it appears under three years of age and is characterized by purpuric skin lesions, fever and edema. A three years-old boy, who has cough and coryzea was admitted to our clinic for fever and red spots on legs and arms. In physical examination; ecimotic skin lesions on right ear, face, arms, dorsal of the hands, buttocks, legs and dorsal of the feet were found. In the laboratory tests acute phase reactants were elevated and blood coagulation tests were in normal range. Hepatit A,B,C and TORCH markers were negative. Punch biopsy obtained from gluteal area showed leukositoclastic vasculity. Focal fibrinogen accumulation was detected by immun fluorescent microscopy. Regression on lesions was not observed despite supportive therapy, so prednisolone (1 mg/kg/day therapy was started. On the third day of the steroid therapy, complete recovery was achived.

    1979-01-01

    The patogenesis and etiology of acute ataxia in childhood is not well known. It may occur without previous symptoms or may be the expression of specific infectious diseases. Forty patients hospitalized at the Hospital de Niños de Buenos Aires en 1972-1978, were studied. The neurological manifestations showed an acute onset, being ataxia the main sign, associate to tremor, nystagmus, dysartria, oculo-motor paresia, muscular weakness, and hyporeflexia. Most of the patients (82%) became cured within the first four weeks. It is advisable to establish a follow-up with periodic controls, mainly in those patients in whom an association with previous infectious diseases did not exist to be able to detect an association with degenerative or desmyelinizing diseases.

    Fifty-six patients, selected by clinical criteria, underwent angiography for suspected acute mesenteric ischemia. Twenty-nine patients subsequently did not have mesenteric ischemia and had negative arteriograms. Twenty-seven patients had mesenteric ischemia: arterial thrombosis (three), arterial embolus (seven), venous thrombosis (five), vasculitis with thrombosis (one), and nonocclusive ischemia (11). Of these 27 patients, 12 (44%) received intraarterial vasodilator infusions. Overall, 13 (48%) of the 27 patients survived their hospitalization, including five (45%) of 11 with nonocclusive ischemia. This experience confirms that nonocclusive ischemia is the most common form of the disorder diagnosed by angiography. Most patients with mesenteric ischemia are candidates for intraarterial vasodilator therapy. Early angiography in patients with suspected acute mesenteric ischemia permits early diagnosis and differentiation between occlusive and nonocclusive types. Interventional infusion therapy may improve survival

    2014-01-01

    Over the past two decades, hematologic malignancies have been extensively evaluated due to the introduction of powerful technologies, such as conventional karyotyping, FISH analysis, gene and microRNA expression profiling, array comparative genomic hybridization and SNP arrays, and next-generation sequencing (including whole-exome sequencing and RNA-seq). These analyses have allowed for the refinement of the mechanisms underlying the leukemic transformation in several oncohematologic disorders and, more importantly, they have permitted the definition of novel prognostic algorithms aimed at stratifying patients at the onset of disease and, consequently, treating them in the most appropriate manner. Furthermore, the identification of specific molecular markers is opening the door to targeted and personalized medicine. The most important findings on novel acquisitions in the context of acute lymphoblastic leukemia of both B and T lineage and de novo acute myeloid leukemia are described in this review.

    The authors analysed ultrasonography (US) findings in patients with clinical signs of acute appendicitis during a recent 7-months period. The comparative analysis between US findings and surgical-pathologic findings was performed in 193 cases who underwent surgery. There were 52 cases with a sonographically non-visible appendix whose symptoms spontaneously resolved. The inflamed appendix was visualized by high-resolution, real-time US according to the graded-compression method described by Puylaert. The following results noted: 1. Sonographically visualized 136 cases were the target-appearance appendix in 47 cases, the fluid-filled appendix in 66 cases and the irregular marginated mixed echogenic mass-like density with surrounding fluid collection in 23 cases. The appendix was not visualized by US in 109 cases. 2. Appendicitis perforation was predictable in 21 cases of 24 cases. 3. Acute appendicitis was 24 cases (59%) among 41 cases who were sonographically visualized with appendiceal wall thickening less than 3mm and 77 cases (81%) among 95 cases with wall thickening more than 3mm. 4. When the results in women were analyzed separately (n=176), the sensitivity was 86%, the specificity was 76% and the accuracy was 80%. In women, US was helpful for the differential diagnosis between acute appendicitis and other gynecologic disease. 5. In men (n=69), the sensitivity was 88%, the specificity was 67% and the accuracy was 81%. 6. The overall sensitivity was 87%, the specificity was 75% and accuracy was 80% (n=245). Graded-compression US is the examination of choice in the patients with clinical signs of acute appendicitis, particularly in women.

    Full Text Available Acute pancreatitis is a rare complication during chemotherapy for pediatric patients with solid tumors. We report a 9-year-old boy with osteosarcoma who experienced 2 episodes of pancreatitis 1 day and 48 days after infusion of ifosfamide (IFOS, respectively. From a MEDLINE search, this is the 3rd reported case and 2nd reported pediatric case of IFOS-induced pancreatitis, and only this case experienced late-onset pancreatitis.

  11. Oral manifestations of acute leukaemia

    Full Text Available Acute leukaemia is the most common form of chilhood cancer. The aim of this paper was to underline the importance of oral manifestations in children with acute leukaemia. The disease and its treatment can directly or indirectly affect oral health. Oral manifestations are gingival inflammation and enlargement. Leukaemic cells are capable of infiltrating the gingiva and the deeper periodontal tissues which leads to ulceration and infection of oral tissues. Gingival bleeding is a common sign in patients with leukaemia. Symptoms include local lymphadenopathy, mucous membrane Petechiae and ecchymoses. Cytotoxic drugs have direct effects like mucositis, involving atrophy, desquamation and ulceration of the mucosa, with increasing the risk for local and systemic infections. Leukaemia can directly influence dental care and dental treatment, while oral lesions may have life-threatening consequences. Knowledge and skills among dentists may also not be adequate to treat children with acute leukaemia. It is therefore imperative that all stomatologists be aware of dental problems that occur in leukaemia in order to be able to effectively carry out appropriate measures to mitigate these problems.

    Statins are the main resource available to reduce LDL-cholesterol levels. Their continuous use decreases cardiovascular morbidity and mortality due to atherosclerosis. The administration of these medications demonstrated to be effective in primary and secondary prevention clinical trials in low and high risk patients. Specialists believe that a possible benefit of hypolipidemic therapy in preventing complications of atherosclerotic diseases is in the reduction of deposition of atherogenic lipoproteins in vulnerable areas of the vasculature. Experimental studies with statins have shown an enormous variety of other effects that could extend the clinical benefit beyond the lipid profile modification itself. Statin-based therapies benefit other important components of the atherothrombotic process: inflammation, oxidation, coagulation, fibrinolysis, endothelial function, vasoreactivity and platelet function. The demonstration of the effects that do not depend on cholesterol lowering or the pleiotropic effects of statins provides the theoretical basis for their potential role as adjunctive therapy in acute coronary syndromes. Retrospective analyses of a variety of studies indicate the potential benefit of statins during acute coronary events. Recent clinical studies have addressed this important issue in prospective controlled trials showing strong evidence for the administration of statins as adjunctive therapy in acute coronary syndromes.

    Experimental infections with the NC-1 strain of Neospora caninum were conducted in gerbils (Meriones unguiculatus) to determine their acute responses to experimental intraperitoneal infection. Five groups of five female gerbils were used and they were intraperitoneally infected with 1x10(6), 2x10(6), 3x10(6), 4x10(6) or 5x10(6) tachyzoites. Gerbils in all groups developed clinical signs of neosporosis which consisted of inactivity 4-5 days post-inoculation. Morbidity and mortality were observed in all groups. Grossly there was a clear fibrinous exudate in the abdominal cavity and adhesions of the spleen and pancreas to the stomach in gerbils suffering from acute neosporosis. The LD50 was calculated as 9.3x10(5) tachyzoites per gerbil. The results indicate that gerbils can be used as a suitable model of acute neosporosis. This model can be used to screen candidate treatments and to test the efficacy of vaccines for neosporosis without the need to use histology or PCR to demonstrate treatment efficacy.

    Some infectious organisms may give rise to acute pancreatitis; brucellosis, however, extremely rarely leads to acute pancreatitis. A 40-year-old man was diagnosed with acute pancreatitis, the etiology of which was determined to be acute brucellosis. The patient was discharged without complications approximately 15 days after the initiation of trimethoprim-sulfamethoxazole and doxycycline treatment. Brucella infections may rarely be complicated by acute pancreatitis. Thus, brucellosis should be remembered in the etiology of acute pancreatitis in regions such as Turkey, where Brucella infections are endemic.

    2011-08-01

    Full Text Available Acute intermittent porphyria (AIP is a rare autosomal dominant disorder of heme biosynthesis in liver due to deficiency of porphobilinogen deaminase enzyme. Clinically, AIP is dominatedby a colicky type pain, which does not subside after taking usual analgesics. Additional frequent symptoms are vomiting, hypertension, peripheral neuropathy, seizures, depression, delirium and coma. This paper reported a case of a twenty-fi- ve-year-old female patient, who had undergone a period of six days between the first presentationto the medical department and the diagnosis confirmation. It has accentuated possible mistakes in symptomatic therapy administration as well as dangers of a delayed diagnosis.

    In people with acute pancreatitis, it is unclear what the role should be for medical treatment as an addition to supportive care such as fluid and electrolyte balance and organ support in people with organ failure. To assess the effects of different pharmacological interventions in people with acute pancreatitis. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, 2016, Issue 9), MEDLINE, Embase, Science Citation Index Expanded, and trial registers to October 2016 to identify randomised controlled trials (RCTs). We also searched the references of included trials to identify further trials. We considered only RCTs performed in people with acute pancreatitis, irrespective of aetiology, severity, presence of infection, language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and extracted data. We did not perform a network meta-analysis as planned because of the lack of information on potential effect modifiers and differences of type of participants included in the different comparisons, when information was available. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) for the binary outcomes and rate ratios with 95% CIs for count outcomes using a fixed-effect model and random-effects model. We included 84 RCTs with 8234 participants in this review. Six trials (N = 658) did not report any of the outcomes of interest for this review. The remaining 78 trials excluded 210 participants after randomisation. Thus, a total of 7366 participants in 78 trials contributed to one or more outcomes for this review. The treatments assessed in these 78 trials included antibiotics, antioxidants, aprotinin, atropine, calcitonin, cimetidine, EDTA (ethylenediaminetetraacetic acid), gabexate, glucagon, iniprol, lexipafant, NSAIDs (non-steroidal anti-inflammatory drugs), octreotide, oxyphenonium, probiotics, activated protein C, somatostatin, somatostatin plus omeprazole, somatostatin

    In a prospective study of 91 patients with acute pancreatitis, computed tomographic (CT) findings were correlated with the clinical type of acute pancreatitis. In acute edematous pancreatitis (63 patients; 16 with repeat CT), CT was normal (28%) or showed inflammation limited to the pancreas (61%). Phlegmonous changes were present in 11%, including one patient with focal pancreatic hemorrhage, indicating that clinically unsuspected hemorrhagic pancreatitis can occur. In acute necrotizing (hemorrhagic, suppurative) pancreatitis (nine patients; eight with repeat CT), no patient had a normal CT scan and 89% had phlegmonous changes. One patient had hemorrhagic pancreatitis and three had abscesses. In acute exacerbation of chronic pancreatitis (10 patients; three with repeat CT), there were pancreatic calcifications (70%), a focal mass (40%), and pancreatic ductal dilation (30%). On follow-up CT, the findings of acute pancreatitis did not always disappear with resolution of the clinical symptons. This was especialy true of phlegmonous pancreatitis, where the CT findings could persist for months

    Full Text Available Introduction: Acute epiploic appendagitis is a relatively rare disease that mimics a varied number of diseases. Presentation of case: In this paper we report a 24-year-old male who presented with epiploic appendagitis that might have been misdiagnosed by physicians due to its equivocal presentation imitating more common acute abdominal conditions like acute appendicitis or acute diverticulitis depending on the site of the inflamed appendage. Discussion: The clinical presentation, investigations findings and both conservative and surgical interventions of the patient are mentioned within the report. Conclusion: Radiological imaging like enhanced CT scan of the abdomen has an important role in differentiating acute epiploic appendigitis from other acute abdominal conditions along with the proper physical examination, thus promoting conservative management and avoiding surgery. However, failure of conservative management might lead to the surgical intervention. Keywords: Epiploic appendagitis, Laparoscopy, CT scan, Conservative, Surgery

To determine the role of sonography in the differential diagnosis of acute appendicitis, preappendectomy sonographic data of 164 consecutive cases in Fatemeh-Zahra Teaching Hospital were evaluated. Of 113 (68.9% patients who had acute appendicitis in histopathology, 64 (56.6% cases had preoperative sonographic diagnosis of acute appendicitis. Of 51 patients who had normal appendices, 40 (78.4% cases had normal appendices in sonographic evaluations. Sensitivity, specificity and accuracy of sonography for acute appendicitis were 56.7%, 78.4% and 0.63, respectively. The positive and negative predictive values were 85.3% and 44.49% respectively. As a result, sonographic evaluation is an additional diagnostic tool in acute appendicitis.

    Acute eosinophilic pneumonia is one of a recently described idiopathic eosinophilic lung disease, which differs from chronic eosinophilic pneumonia. Patients with acute eosinophilic pneumonia develop acute onset of dyspnea, hypoxemia, diffuse pulmonary infiltrates and pleural effusion on chest radiograph, and show an increase in number of eosinophils in bronchoalveolar lavage fluid or lung biopsy specimen. Prompt and complete response to corticosteroid therapy without any recurrence is characteristically seen in patient with this disease. Although the etiology of acute eosinophilic pneumonia is not known, it has been suggested to be related to a hypersensitivity phenomenon to an unidentified inhaled antigen. We report four cases of acute eosinophilic pneumonia presented with acute onset of dyspnea, diffuse pulmonary infiltrates on chest radiograph, and eosinophilia in bronchoalveolar lavage fluid in previously healthy adults

    A 25-year-old woman had signs of an acute surgical abdomen. Differential diagnoses were ectopic pregnancy and acute appendicitis. Diagnostic laparoscopy revealed an apparent inflamed appendix and left-sided unruptured tubal ectopic pregnancy. This case illustrates the importance of considering multiple pathologic disorders in a patient with an acute surgical abdomen, especially in pregnancy. Furthermore, it shows that laparoscopy constitutes the optimal treatment modality in patients with multiple diagnoses, because it combines multifocal diagnosis and treatment without additional postoperative morbidity.

    The epidemiology of dialysis requiring acute kidney injury (AKI-D) in acute ischemic stroke (AIS) and intracerebral hemorrhage (ICH) admissions is poorly understood with previous studies being from a single center or year. We used the Nationwide Inpatient Sample to evaluate the yearly incidence trends of AKI-D in hospitalizations with AIS and ICH from 2002 to 2011. We also evaluated the trend of impact of AKI-D on in-hospital mortality and adverse discharge using adjusted odds ratios (aOR) after adjusting for demographics and comorbidity indices. We extracted a total of 3,937,928 and 696,754 hospitalizations with AIS and ICH, respectively. AKI-D occurred in 1.5 and 3.5 per 1000 in AIS and ICH admissions, respectively. Incidence of admissions complicated by AKI-D doubled from 0.9/1000 to 1.7/1000 in AIS and from 2.1/1000 to 4.3/1000 in ICH admissions. In AIS admissions, AKI-D was associated with 30% higher odds of mortality (aOR, 1.30; 95% confidence interval, 1.12-1.48; Paccident continues to grow and is associated with increased mortality and adverse discharge. This highlights the need for early diagnosis, better risk stratification, and preparedness for need for complex long-term care in this vulnerable population. © 2015 American Heart Association, Inc.

    2002-01-01

    Objective: To determine whether laparoscopic cholecystectomy (LC) should be the procedure of choice in treating acute cholecystitis. Method: A prospective study was conducted over a 4 1/2-year period. There were 187 patients with acute cholecystitis out of 1020 patients with gallbladder disease who required cholecystectomy. These patients were divided into three groups based on the time interval between the onset of pain and the time patients sought medical attention: Group 1, 7 days. All the patients underwent LC after a comprehensive preoperative workup. The parameters analyzed included operating time, hospital stay, and conversion rate. The comparison was made among the various groups and with those who had elective LC. Results: One hundred twenty patients (64.17%) presented for treatment within 3 to 7 days of the onset of an attack. Empyema of the gallbladder was seen in 106 (56.68%) patients and phlegmon of the gallbladder in 42 (22.46%) patients. Group 3 patients had an operative time of 56.2 min as opposed to 18.5 min in Group 1 and 17.5 min in the elective LC group. The conversion rate in Group 3 was 19.5% versus 3.8% in Group 1 and 3.48% in the elective LC group. The complication rate was 7.3% in Group 3, 3.8% in Group 1, and 3.7% in the elective LC group. Conclusion: Acute cholecystitis is better managed by laparoscopic cholecystectomy, except in the patients presenting with a gallbladder phlegmon later than 7 days after the onset of the attack.

  13. Perfusion CT in acute stroke

    2015-01-01

    Modern multislice CT scanners enable multimodal protocols including non-enhanced CT, CT angiography, and CT perfusion. A 64-slice CT scanner provides 4-cm coverage. To cover the whole brain, a 128 - 256-slice scanner is needed. The use of perfusion CT requires an optimized scan protocol in order to reduce exposure to radiation. As compared to non-enhanced CT and CT angiography, the use of CT perfusion increases detection rates of cerebral ischemia, especially small cortical ischemic lesions, while the detection of lacunar and infratentorial stroke lesions remains limited. Perfusion CT enables estimation of collateral flow in acute occlusion of large intra- or extracranial arteries. Currently, no established reliable thresholds are available for determining infarct core and penumbral tissue by CT perfusion. Moreover, perfusion parameters depend on the processing algorithms and the software used for calculation. However, a number of studies point towards a reduction of cerebral blood volume (CBV) below 2 ml/100 g as a critical threshold that identifies infarct core. Large CBV lesions are associated with poor outcome even in the context of recanalization. The extent of early ischemic signs on non-enhanced CT remains the main parameter from CT imaging to guide acute reperfusion treatment. Nevertheless, perfusion CT increases diagnostic and therapeutic certainty in the acute setting. Similar to stroke MRI, perfusion CT enables the identification of tissue at risk of infarction by the mismatch between infarct core and the larger area of critical hypoperfusion. Further insights into the validity of perfusion parameters are expected from ongoing trials of mechanical thrombectomy in stroke.

    Agitation in psychiatry is defined as "a request to which an answer cannot be deferred". If some types of controllable agitation can be solved by human means or psychotropic drugs, others may require the intervention of intensivists who will contribute to the onset of crisis resolution. In addition, an organic aetiology must be carefully excluded a before considering a psychiatric origin of agitation, especially in patients with no psychiatric history and in the elderly. Indeed, acute agitation can hide serious somatic traps and be life threatening.

    We describe a syndrome in which empty hernial sac, in its role of peritoneal recess, becomes distended with pus during or after general peritonitis, usually caused by acute appendicitis. Until 1998, only 14 pediatric cases were described in the literature. We presented here eight cases of patients who experienced inguinal symptoms. In four, appendectomy was performed; in four, this was secondary to necrotizing enterocolitis. Inguinal complaints, pain, and flogosis were present in first group, while pneumoperitoneum and visible duct vaginalis were present in second group. These cases demonstrated that persistent patent processus vaginalis may predispose to inguinal pathology secondary to intraabdominal sepsis and represent a unique complication.

    Most cases of acute otitis media (AOM) resolve even without antibiotic treatment. In the pre-antibiotic era, AOM complications were common and could lead to deafness and neurological sequelae. With the use of antibiotics, the complications have become less frequent, but they may still evolve. The possible increase in the occurrence of complications has to be considered if we start treating AOM more conservatively and if bacterial antibiotic resistance situation becomes more problematic. These rare but possibly lethal complications should be diagnosed and treated promptly. The need for cochlear implantation has to be evaluated soon after an episode of meningitis if deafness is suspected.

    Full Text Available Shewanella algae is an emerging bacteria rarely implicated as a human pathogen. Previously reported cases of S. algae have mainly been associated with direct contact with seawater. Here we report the isolation of S. algae as the sole etiological agent from a patient suffering from acute gastroenteritis with bloody diarrhoea. The bacterium was identified by automated identification system and 16S rRNA gene sequence analysis.

    Full Text Available Abstract Background Acute pancreatitis rarely complicates pregnancy. Although most pregnant women with acute pancreatitis have associated gallstones, less common causes such as drugs have been reported. Case presentation We report the case of a 34-year-old woman who underwent medical abortion with mifepristone and gemeprost and received codeine as pain-relief during the induction of abortion. She developed a severe acute necrotizing pancreatitis which required 14 days of intensive care. Other possible etiological factors, i.e. gallstone, alcohol intake and hyperlipidemia, were excluded. Conclusions The reported case of acute pancreatitis was most likely drug-induced.

    Acute carbon monoxide poisoning has frequently occurred in Korean, because of the coal briquette being widely used as fuel in Korean residences. Carbon monoxide poisoning has been extensively studied, but it has been sparsely reported that pulmonary edema may develop in acute CO poisoning. We have noticed nine cases of pulmonary edema in acute CO poisoning last year. Other possible causes of pulmonary edema could be exclude in all cases but one. The purpose of this paper is to describe nine cases of pulmonary edema complicated in acute CO poisoning and discuss the pathogenesis and the prognosis

    As the incidence of acute pancreatitis continues to rise, establishing the etiology in order to prevent recurrence is important. Although the etiology of acute pancreatitis is not difficult in the majority of patients, almost a quarter of patients are initially labeled as having idiopathic acute pancreatitis. When confronted with a patient with acute pancreatitis and no clear etiology defined as an absence alcoholism, gallstones (ultrasound and/or MRI), a normal triglyceride level, and absence of tumor, it often appears reasonable to consider a drug as the cause of acute pancreatitis. Over 100 drugs have been implicated by case reports as causing acute pancreatitis. While some of these case reports are well written, many case reports represent poorly written experiences of the clinician simply implicating a drug without a careful evaluation. Over-reliance on case reports while ignoring randomized clinical trials and large pharmacoepidemiologic surveys has led to confusion about drug induced acute pancreatitis. This review will explain that drug induced acute pancreatitis does occur, but it is rare, and over diagnosis leads to misconceptions about the disease resulting in inappropriate patient care, increased litigation and a failure to address the true entity: idiopathic acute pancreatitis.

    Food allergy, a commonly increasing problem worldwide, defined as an adverse immune response to food. A variety of immune-related effector cells such as mast cells, eosinophils, neutrophils, and T cells are involved in food-related allergic responses categorized as IgE mediated, non-IgE mediated, and mixed (IgE and non-IgE) depending upon underlying immunological mechanisms. The dietary antigens mainly target the gastrointestinal tract including pancreas that gets inflamed due to food allergy and leads acute pancreatitis. Reports indicate several food proteins induce pancreatitis; however, detailed underlying mechanism of food-induced pancreatitis is unexplored. The aim of the review is to understand and update the current scenario of food-induced pancreatitis. A comprehensive literature search of relevant research articles has been performed through PubMed, and articles were chosen based on their relevance to food allergen-mediated pancreatitis. Several cases in the literature indicate that acute pancreatitis has been provoked after the consumption of mustard, milk, egg, banana, fish, and kiwi fruits. Food-induced pancreatitis is an ignored and unexplored area of research. The review highlights the significance of food in the development of pancreatitis and draws the attention of physicians and scientists to consider food allergies as a possible cause for initiation of pancreatitis pathogenesis.

    2003-10-01

    Patients with predicted severe necrotizing pancreatitis as diagnosed by C-reactive protein (>150 mg/L) and/or contrast-enhanced computed tomography should be managed in the intensive care unit. Prophylactic broad-spectrum antibiotics reduce infection rates and survival in severe necrotizing pancreatitis. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy is a causative therapy for gallstone pancreatitis with impacted stones, biliary sepsis, or obstructive jaundice. Fine needle aspiration for bacteriology should be performed to differentiate between sterile and infected pancreatic necrosis in patients with sepsis syndrome. Infected pancreatic necrosis in patients with clinical signs and symptoms of sepsis is an indication for surgery. Patients with sterile pancreatic necrosis should be managed conservatively. Surgery in patients with sterile necrosis may be indicated in cases of persistent necrotizing pancreatitis and in the rare cases of "fulminant acute pancreatitis." Early surgery, within 14 days after onset of the disease, is not recommended in patients with necrotizing pancreatitis. The surgical approach should be organ-preserving (debridement/necrosectomy) and combined with a postoperative management concept that maximizes postoperative evacuation of retroperitoneal debris and exudate. Minimally invasive surgical procedures have to be regarded as an experimental approach and should be restricted to controlled trials. Cholecystectomy should be performed to avoid recurrence of gallstone-associated acute pancreatitis.

    The MRI examinations of seven patients with acute transverse myelopathy (ATM) were analysed. The patients were examined 2-5 times during the course of their disease with short and long TR/TE spin-echo sequences in the sagittal projection. A previous history of autoimmune disorder and/or signs of infection at the onset of ATM were present in all cases. Cerebrospinal fluid analysis showed local synthesis of immunoglobulin in the nervours system in three cases and signs of infectious myelitis in one. During the acute phase four patients had local enlargement of the cord and all had increased signal on long TR/TE sequences. The outcome was grave in the majority of patients and there seemed to be a correlation between the degree of cord enlargement, persistence of increased signal intensity and limited recovery. Atrophy and remaining high signal intensity were noted on late MRI patients with poor outcome. In one patient with probable anterior spinal artery occlusion, cavitation of the cord was seen. (orig.)

    The present article analyzes the main presentations on acute pancreatitis (AP) in Digestive Disease Week 2013. Perfusion computed tomography allows early diagnosis of pancreatic necrosis. Neutrophil gelatinase-associated lipocalin predicts the development of acute renal failure, severe AP and death. Factors associated with greater fluid sequestration in AP are alcoholic etiology, an elevated hematocrit, and the presence of criteria of systemic inflammatory response syndrome; fluid sequestration is associated with a worse outcome. True pseudocysts (fluid collections without necrosis for more than 4 weeks) are a highly infrequent complication in AP. Patients with necrotic collections have a poor prognosis, especially if associated with infection. A meta-analysis on fluid therapy suggests that early aggressive fluid administration is associated with higher mortality and more frequent respiratory complications. According to a meta-analysis, enteral nutrition initiated within 24 hours of admission improves the outcome of AP compared with later initiation of enteral nutrition. Pentoxifylline could be a promising alternative in AP; a double-blind randomized study showed that this drug reduced the length of hospital and intensive care unit stay, as well as the need for intensive care unit admission. The association of octreotide and celecoxib seems to reduce the frequency of organ damage compared with octreotide alone. Mild AP can be managed in the ambulatory setting through hospital-at-home units after a short, 24-hour admission. Copyright © 2013 Elsevier España, S.L. All rights reserved.

  12. Epidemiology of acute lymphoblastic leukemia

    1985-01-01

    Although the etiology of acute leukemia is largely unknown, some facets of the puzzle are becoming clarified. Recognition of important patterns in age-specific mortality rates has suggested that events early in life, perhaps even prenatally, may have an influence on developing leukemia in childhood. The racial differences evident in mortality, incidence, and immunologic subtype of ALL suggest either differences in exposures to certain factors or differences in responses to those factors by white children. Hereditary factors appear to play a role. Familial and hereditary conditions exist that have high incidences of acute leukemia. Chromosomal anomalies are common in these conditions. Viral infections may play a role by contributing to alteration in genetic material through incorporation of the viral genome. How that virus is dealt with after primary infection seems important. The presence of immunodeficiency may allow wider dissemination or enhanced replication of such viruses, thereby increasing the likelihood of cellular transformation to an abnormal cell. Proliferation of that malignant cell to a clone may depend on other cofactors. Perhaps prolonged exposure to substances like benzene or alkylating agents may enhance these interactions between virus and genetic material. Does this change DNA repair mechanisms. Are viral infections handled differently. Is viral genomic information more easily integrated into host cells. Ionizing radiation has multiple effects. Alteration in genetic material occurs both at the molecular and chromosomal levels. DNA may be altered, lost, or added in the cell's attempt to recover from the injury

  13. Plasma Sphingolipids in Acute Pancreatitis

    2017-12-01

    Full Text Available Acute pancreatitis (AP is a prevalent gastrointestinal disorder associated with systemic inflammatory response syndrome and, in the case of severe AP, a mortality rate ranging from 36% to 50%. Standard clinical treatment of AP includes intensive hydration, analgesia, and management of complications. Unfortunately, the direct treatment of AP at the level of its molecular pathomechanism has not yet been established. Recent studies indicate that the sphingolipid signaling pathway may be one of the important factors contributing to the development of inflammation in pancreatic diseases. In the current study, we sought to investigate this promising route. We examined the plasma sphingolipid profile of 44 patients with acute pancreatitis, dividing them into three groups: mild, moderate and severe AP. Samples were collected from these groups at days 1, 3 and 7 following their hospital admission. We demonstrated significant changes in blood plasma sphingolipids in relation to the time course of AP. We also found an inhibition of de novo ceramide synthesis in mild and moderate AP. However, the most important and novel finding was a significant elevation in sphingosine-1-phosphate (S1P (a downstream metabolite of ceramide in mild AP, as well as a dramatic reduction in the lipid molecule content in the early stage (days 1 and 3 of severe AP. This strongly indicates that plasma S1P could serve as a prognostic marker of AP severity.

    Full Text Available Susan T Verghese, Raafat S HannallahThe George Washington University Medical Center, Division of Anesthesiology, Children’s National Medical Center, Washington, DC, USAAbstract: The greatest advance in pediatric pain medicine is the recognition that untreated pain is a significant cause of morbidity and even mortality after surgical trauma. Accurate assessment of pain in different age groups and the effective treatment of postoperative pain is constantly being refined; with newer drugs being used alone or in combination with other drugs continues to be explored. Several advances in developmental neurobiology and pharmacology, knowledge of new analgesics and newer applications of old analgesics in the last two decades have helped the pediatric anesthesiologist in managing pain in children more efficiently. The latter include administering opioids via the skin and nasal mucosa and their addition into the neuraxial local anesthetics. Systemic opioids, nonsteroidal anti-inflammatory agents and regional analgesics alone or combined with additives are currently used to provide effective postoperative analgesia. These modalities are best utilized when combined as a multimodal approach to treat acute pain in the perioperative setting. The development of receptor specific drugs that can produce pain relief without the untoward side effects of respiratory depression will hasten the recovery and discharge of children after surgery. This review focuses on the overview of acute pain management in children, with an emphasis on pharmacological and regional anesthesia in achieving this goal.Keywords: pediatric pain treatment, pain medication in children, pediatric regional anesthesia, pca and pcea in children, epidural additives

    To evaluate the clinical picture and microbiological findings of children hospitalized due to acute otitis media and to analyze how it differs from acute mastoiditis. A retrospective review of the medical records of all children (0-16 years) hospitalized due to acute otitis media in the Department of Otorhinolaryngology at the Helsinki University Hospital, between 2003 and 2012. Comparison with previously published data of children with acute mastoiditis (n=56) from the same institute and period of time. The most common pathogens in the children hospitalized due to acute otitis media (n=44) were Streptococcus pneumoniae (18%), Pseudomonas aeruginosa (16%), Streptococcus pyogenes (14%), and Staphylococcus aureus (14%). One of the most common pathogens of out-patient acute otitis media, Haemophilus influenzae, was absent. Otorrhea was common in infections caused by S. pyogenes and otorrhea via tympanostomy tube in infections caused by P. aeruginosa. In children under 2 years-of-age, the most common pathogens were S. pneumoniae (43%), Moraxella catarrhalis (14%), and S. aureus (7%). S. pyogenes and P. aeruginosa were only found in children over 2 years-of-age. Previous health problems, bilateral infections, and facial nerve paresis were more common in children hospitalized due to acute otitis media, compared with acute mastoiditis, but they also demonstrated lower CRP values and shorter duration of hospital stay. The number of performed tympanostomies and mastoidectomies was also comparatively smaller in the children hospitalized due to acute otitis media. S. aureus was more common and S. pneumoniae, especially its resistant strains, was less common in the children hospitalized due to acute otitis media than acute mastoiditis. Acute otitis media requiring hospitalization and acute mastoiditis compose a continuum of complicated acute otitis media that differs from common out-patient acute otitis media.

    Science.gov (United States)

    Hill, N

    2001-03-01

    The increasing use of NPPV in both acute and chronic settings has added to ventilator options in the post acute setting. Some patients start NPPV during their acute presentation and continue use during their post acute stay. Others are difficult to wean from invasive mechanical ventilation, and, if selected carefully, can be extubated and weaned using NPPV. Still others may initiate NPPV in the post acute setting with the anticipation of long-term use. In any care settings, principles of patient selection and management in monitoring practices overlap considerably. Noninvasive ventilation has been shown to reduce morbidity, mortality, and hospital stay in the acute setting for selected patients, and almost certainly prolongs survival for patients with restrictive thoracic disorders in the chronic setting. Although efficacy studies have not been performed in the post acute setting, it is reasonable to anticipate that appropriate use of NPPV will yield similar benefits. Accordingly, clinicians working in the post acute setting must acquire skill and experience in the proper application of NPPV to optimally manage the increasing number of patients treated with NPPV in this expanding arena.

    Background Multiple acute cerebral infarcts in different arterial territories may be caused by several emboli concurrently or successively. Aim and/or hypothesis We hypothesized that the time from stroke onset to magnetic resonance imaging may shed light on underlying mechanisms of multiple acute cerebral infarcts. Methods This is a prospective observational cohort study involving 2697 ischemic stroke patients conducted at Haukeland University Hospital between February 2006 and October 2013. Only patients with diffusion-weighted imaging lesions in more than one arterial territory (left or right anterior circulation or posterior circulation) were included. The time from stroke onset to magnetic resonance imaging was registered and correlated with the etiology of multiple acute cerebral infarcts in each patient. Results We reviewed 2697 consecutive patients and 2220 (82%) underwent magnetic resonance imaging. Among these 2125 (96%) had diffusion-weighted imaging lesions. We found 187 multiple acute cerebral infarct patients who were then included in the study. There was positive correlation (0.20; p time to magnetic resonance imaging and frequency of multiple acute cerebral infarcts caused by internal carotid stenosis. There was no correlation (-.02) between time to magnetic resonance imaging and frequency of multiple acute cerebral infarcts caused by cardiogenic embolism. Conclusions Multiple acute cerebral infarcts associated with cardiogenic embolism seem to happen concurrently as a shower of emboli whereas multiple acute cerebral infarcts associated with internal carotid artery stenosis seem to occur successively separated by hours or days.

    Acute cholecystitis and pancreatitis are acute forms of cholecystolithiasis. The presence of acute cholecystitis can lead to important changes in therapy in the early course of acute pancreatitis. The aim of this study was to identify the accuracy of ultrasonography in diagnosing acute cholecystitis with coexistent acute pancreatitis. Subjects were all those patients admitted to our hospital with a diagnosis of acute pancreatitis between 1998 and 2015 who underwent cholecystectomy within 15 days of the ultrasonography performed on admittance. Patient data were analyzed retrospectively to compare the ultrasound findings with the pathological findings of the resected gallbladders. Patients were allocated to two groups according to the signs of acute cholecystitis on ultrasonography: group 1 negative and group 2 positive. One hundred and twenty patients were enrolled in the study: 77 in group 1 and 43 in group 2. Similar results were found for the two groups with respect to the pathological diagnosis of acute cholecystitis, i.e., 31.2 % for group 1 and 27.9 % for group 2. Analysis indicated that there was no correlation between the ultrasonography data and pathological findings (p = 0.708). On the basis of our study, ultrasound findings alone cannot be used to accurately diagnose acute cholecystitis in the setting of acute pancreatitis.

    Acute pancreatitis is one of the most common GI conditions requiring acute hospitalisation and has a rising incidence. In recent years, important insights on the management of acute pancreatitis have been obtained through numerous randomised controlled trials. Based on this evidence, the treatment of acute pancreatitis has gradually developed towards a tailored, multidisciplinary effort, with distinctive roles for gastroenterologists, radiologists and surgeons. This review summarises how to diagnose, classify and manage patients with acute pancreatitis, emphasising the evidence obtained through randomised controlled trials. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  13. Acute pulmonary parenchymal densities in the adult

    International Nuclear Information System (INIS)

    Murphy, C.H.; Murphy, M.R.

    1987-01-01

    The thrust of the radiographic interpretation is to correlate the often non-specific appearance of any parenchymal density with its time-table of development, rate of change, distribution, and the patient's clinical status. Although this chapter contains separate sections on each major cause of acute pulmonary opacification, the intent of the chapter overall is their differential diagnosis. Before beginning to deal with acute pulmonary densities, it is stressed that acute densities can only be differentiated from chronic ones by reviewing preoperative or pre-existing studies. Without the baseline comparison film or reliable presumption of prior normalcy, the acuteness of a parenchymal density may not be apparent until later examinations reveal change or resolution. Also, as discussed is baseline pathology that is altered by the portable technique can be terribly confusing when attempting to evaluate a single isolated film in an acute clinical situation

  14. Acute bile nephropathy secondary to anabolic steroids.

    2016-02-01

    Renal dysfunction in cholestatic liver disease is multifactorial. Acute kidney injury may develop secondary to renal vasoconstriction in the setting of peripheral vasodilation and relative hypovolemia, tubular obstruction by bile casts, and direct tubular toxicity from bile. Anabolic steroids are frequently used by athletes to boost endurance and increase muscle mass. These agents are a recently recognized cause of hepatotoxicity and jaundice and may lead to acute kidney injury. To increase awareness about this growing problem and to characterize the pathology of acute kidney injury in this setting, we report on a young male who developed acute kidney injury in the setting of severe cholestatic jaundice related to ingestion of anabolic steroids used for bodybuilding. Kidney biopsy showed bile casts within distal tubular lumina, filamentous bile inclusions within tubular cells, and signs of acute tubular injury. This report supports the recently re-emerged concept of bile nephropathy cholemic nephrosis.

    Acute appendicitis is the most common surgical non-obstetric pathology during pregnancy. In this report, pregnant patients operated with a diagnosis of acute appendicitis in the last three years are evaluated retrospectively. Between January 2009 and January 2011, 20 pregnant patients were operated for acute appendicitis. Patients were evaluated regarding age, gestational age, clinical and laboratory examinations, imaging studies, operative findings, mean hospital stay, mean operative time, and outcome. In 17 of 20 patients, acute appendicitis was confirmed and appendectomy was performed. Ten of the patients were operated with laparoscopic technique and the remaining 10 had open appendectomy. There was no fetal or maternal morbidity or mortality in any patient. All 20 patients delivered healthy babies during the postoperative course. Acute appendicitis is a challenging diagnosis in the pregnant patient; however, early surgical intervention should be performed with any suspicion. The type of surgery depends on the surgeon's preference and experience.

    2009-04-01

    Trichlorfon (o-o-dimethyl-2,2,2-trichloro-hydroxyethylphosphate), an organophosphate, has a moderately potent anticholinesterase activity. Organophosphate poisoning is well known for its characteristic symptoms and signs, but acute hemolysis caused by trichlorfon is rarely reported. We present a patient who developed acute hemolysis and renal function impairment after percutaneous trichlorfon exposure. A 54-year-old man applied trichlorfon powder to his dog to kill its parasites. Half an hour later, the dog was suspected to die of cholinergic crisis and the patient felt abdominal cramping pain. Later, he developed severe nausea, vomiting, chills, high fever, and cold sweat. Laboratory work-up disclosed a picture of acute hemolysis, jaundice, renal function impairment and leukocytosis. However, there were no clinical features of acute cholinergic syndrome except gastrointestinal symptoms, and blood cholinesterase activities were also normal. He eventually had a full recovery. Trichlorfon should be added to the toxins known to cause acute hemolysis.

    Preoperative images of acute appendiceal diverticulitis are rarely reported because of the difficulty of distinguishing appendiceal diverticulitis from other ileocecal diseases like acute appendicitis or cecal diverticulitis. We report a case of preoperatively diagnosed acute appendiceal diverticulitis. A 30-year-old female with a presumptive diagnosis of acute appendicitis from history and physical examination was admitted to our hospital. Ultrasound sonography showed inflamed appendiceal diverticula and inflammatory changes of the surrounding tissue. The swollen appendix was detected but its findings were slightly different from those of typical acute appendicitis in the following points. One difference was the thickened wall of the appendix, the other difference was the presence of air in the appendix. The patient underwent appendectomy and the pathological specimen revealed inflammatory changes of diverticula within the appendix.

  18. Hemorrhagic Colloid Cyst Presenting with Acute Hydrocephaly

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Colloid cysts are benign slow-growing cystic lesions located on the roof of the third ventricle that usually present with symptoms related to gradual rise of intracranial pressure. They mostly remain asymptomatic and sometimes grow progressively and cause diverse symptoms associated with increased intracranial pressure such as headache, diplopia, and sixth cranial nerve palsy. Here we report a 47-year-old female who presented to the emergency department with acute severe headache and nausea/vomiting. On MRI examination acute hydrocephaly due to hemorrhagic colloid cyst was detected. Acute hemorrhage in colloid cysts is extremely rare and may present with symptoms of acute increase in the intracranial pressure. Intracystic hemorrhage is very rarely reported as a complication of colloid cyst presenting with paroxysmal symptoms of acute hydrocephaly.

    1996-01-01

    To study the ranking of CT in the diagnosis of sigma diverticulitis. Comparison of results of the colon monocontrast enema with those obtained via CT and histopathology as gold standard. 32 patients were included who were operated on for sigma diverticulitis. In 30 patients both CT and monocontrast enema were performed and in two patients CT only. Acute inflammatory wall alterations are identified by CT with a sensitivity of 89.7% vs 96.3% via contrast enema. Pericolic reactions of the environment were seen via CT with 89.7% sensitivity. In case of covered perforations CT yielded a sensitivity of 76.5% vs 46.7% via contrast enema. Sensitivity for abscesses and fistulas was in each case 100% with CT. CT may help to identify extraluminal inflammatory changes and complications in diverticulitis. The degree of the inflammation can be classified and the surgical approach suitably influenced, respectively modified. (orig.) [de

  20. [Fluid therapy in acute pancreatitis].

    Science.gov (United States)

    de-Madaria, Enrique

    2013-12-01

    Severe acute pancreatitis (AP) is associated with an increased need for fluids due to fluid sequestration and, in the most severe cases, with decreased peripheral vascular tone. For several decades, clinical practice guidelines have recommended aggressive fluid therapy to improve the prognosis of AP. This recommendation is based on theoretical models, animal studies, and retrospective studies in humans. Recent studies suggest that aggressive fluid administration in all patients with AP could have a neutral or harmful effect. Fluid therapy based on Ringer's lactate could improve the course of the disease, although further studies are needed to confirm this possibility. Most patients with AP do not require invasive monitoring of hemodynamic parameters to guide fluid therapy administration. Moreover, the ability of these parameters to improve prognosis has not been demonstrated. Copyright © 2013 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

  1. Epidemiology of acute wrist trauma

    1993-01-01

    Epidemiological data on wrist injuries in a population can be used for planning by applying them to criteria for care and thus deriving estimates of provisions for care according to currently desirable standards. In a 1-year study all patients > or = 15 years with acute wrist trauma and treated...... in the emergency room were examined according to an algorithm until a diagnosis was established. The overall incidence of wrist trauma was 69 per 10,000 inhabitants per year. Incidence of wrist trauma requiring x-ray examination was 58 per 10,000 per year. The incidence of distal radius fractures was 27 per 10...... using data from a population-based study. A completeness rate of 0.56 (95% confidence interval: 0.31-0.78) was found. An x-ray had been taken for all patients reporting a fracture thus justifying the use of fractures as an incidence measure when comparing groups of patients with wrist trauma....

  2. Exploring the acute myeloid leukaemias

    2013-10-01

    Full Text Available The acute myeloid leukemias are genetically a diverse group of neoplasm with varied clinical behavior and response to treatment. Advances in immunophenotyping, cytogenetics and molecular genetics have resulted in better understanding of their genesis. Risk stratification of different variants is now emerging. Therapy strategies are now increasingly being developed considering the inherent biological behavior of the different subtypes. It is anticipated that in the future, deeper secrets of these once fatal diseases will be unraveled by advances in newer genomic techniques. It is hoped that future use of gene specific tailored therapy and strategies will result in longer survival in cases showing poorer prognosis at present.

    Yair Lampl

    2005-01-01

    Full Text Available Auditory hallucinations are uncommon phenomena which can be directly caused by acute stroke, mostly described after lesions of the brain stem, very rarely reported after cortical strokes. The purpose of this study is to determine the frequency of this phenomenon. In a cross sectional study, 641 stroke patients were followed in the period between 1996–2000. Each patient underwent comprehensive investigation and follow-up. Four patients were found to have post cortical stroke auditory hallucinations. All of them occurred after an ischemic lesion of the right temporal lobe. After no more than four months, all patients were symptom-free and without therapy. The fact the auditory hallucinations may be of cortical origin must be taken into consideration in the treatment of stroke patients. The phenomenon may be completely reversible after a couple of months.

    BACKGROUND: Hypokalemia is one of the most common electrolyte disorders in hospitalized patients. It is associated with a high mortality rate among patients with cardiovascular disease. Whether hypokalemia confers a similar risk in an unselected hospitalized population is not well established....... METHODS: We conducted a prospective cohort study involving all first time admissions (n=11988) to the Acute Medical Department at Odense University Hospital linking potassium level at admission with registry data on patient characteristics, laboratory data, redeemed prescriptions and time of death...... for the period from August 2009 to August 2011. We estimated hazard ratios for all cause mortality within 0-7 days and 8-30 days after admission, comparing patients with hypokalemia at admission (plasma [K(+)] level

    Poisonings with industrial products represent approximately 7% of the cases reported to the poison centres. Ingestion of petroleum distillates induces irritation of the gastrointestinal tract, central nervous system depression and aspiration pneumonitis which may be severe; treatment is mainly supportive. Ethylene and diethylene glycol poisonings produce central nervous system depression, anion gap metabolic acidosis, osmolar gap and acute tubular necrosis; in severe cases, hypocalcaemia, cerebral oedema and heart failure may be observed; treatment often associates supportive measures, haemodialysis and administration of competitive inhibitors of alcohol dehydrogenase (ethanol or 4-methylpyrazole). Glycol ethers induce central nervous system depression and metabolic acidosis; in addition, ethylene glycol monobutyl ether produces haemolysis; monomethyl and monoethyl ethers are responsible for bone marrow and lymphoid organ toxicity, they adversely affect spermatogenesis and are teratogens.

    Propionic acidemia or aciduria is an intoxication-type disorder of organic metabolism. Patients deteriorate in times of increased metabolic demand and subsequent catabolism. Metabolic decompensation can manifest with lethargy, vomiting, coma and death if not appropriately treated. On January 28-30, 2011 in Washington, D.C., Children's National Medical Center hosted a group of clinicians, scientists and parental group representatives to design recommendations for acute management of individuals with propionic acidemia. Although many of the recommendations are geared toward the previously undiagnosed neonate, the recommendations for a severely metabolically decompensated individual are applicable to any known patient as well. Initial management is critical for prevention of morbidity and mortality. The following manuscript provides recommendations for initial treatment and evaluation, a discussion of issues concerning transport to a metabolic center (if patient presents to a non-metabolic center), acceleration of management and preparation for discharge.

  8. Acute corneal hydrops in keratoconus

    Directory of Open Access Journals (Sweden)

    Prafulla K Maharana

    2013-01-01

    Full Text Available Acute corneal hydrops is a condition characterized by stromal edema due to leakage of aqueous through a tear in descemet membrane. The patient presents with sudden onset decrease in vision, photophobia, and pain. Corneal thinning and ectasias combined with trivial trauma to the eye mostly by eye rubbing is considered as the underlying cause. With conservative approach self-resolution takes around 2 to 3 months. Surgical intervention is required in cases of non-resolution of corneal edema to avoid complications and for early visual rehabilitation. Intracameral injection of air or gas such as perflouropropane is the most common surgical procedure done. Recent investigative modality such as anterior segment optical coherence tomography is an extremely useful tool for diagnosis, surgical planning, and postoperative follow up. Resolution of hydrops may improve the contact lens tolerance and visual acuity but most cases require keratoplasty for visual rehabilitation.

    Nigwekar, Sagar U; Waikar, Sushrut S

    2011-11-01

    Acute kidney injury (AKI) is common in hospitalized patients and is associated with significant morbidity and mortality. The incidence of AKI is increasing and despite clinical advances there has been little change in the outcomes associated with AKI. A variety of interventions, including loop diuretics, have been tested for the prevention and treatment of AKI; however, none to date have shown convincing benefits in clinical studies, and the management of AKI remains largely supportive. In this article, we review the pharmacology and experimental and clinical evidence for loop diuretics in the management of AKI. In addition, we also review evidence for other agents with diuretic and/or natriuretic properties such as thiazide diuretics, mannitol, fenoldopam, and natriuretic peptides in both the prevention and treatment of AKI. Implications for current clinical practice are outlined to guide clinical decisions in this field. Copyright © 2011 Elsevier Inc. All rights reserved.

    Deposits of iron and hemosiderosis in the kidney have been observed in diseases with intravascular hemolysis, including paroxysmal nocturnal hemoglobinuria, and valvular heart diseases and prosthetic heart valve implants. However, the decrease in kidney function associated with hemolysis caused by cardiac valvular disease or prostheses is less well recognized. We present a case of intravascular hemolysis after repair and banding of the mitral valve that resulted in massive renal tubular deposition of hemosiderin with decreased kidney function. We discuss the pathophysiologic process of both acute and chronic tubular injury from heme and heme proteins, including injury to organelles resulting in autophagic vacuoles containing damaged organelles, such as mitochondria. We conclude that tubular injury resulting from heme proteins should be considered as a cause of decreased kidney function in all patients with a cardiac valvular disease or prosthesis. PMID:20605299

  11. Nutrition in acute renal failure

    Directory of Open Access Journals (Sweden)

    Sérgio Mussi Guimarães

    Full Text Available Nutritional status has been considered to be one of the possible determinants of mortality rates in cases of acute renal failure (ARF. However, most studies evaluating possible mortality indicators in ARF cases have not focused on the nutritional status, possibly because of the difficulties involved in assessing the nutritional status of critically ill patients. Although the traditional methods for assessing nutritional status are used for ARF patients, they are not the best choice in this population. The use of nutritional support for these patients has produced conflicting results regarding morbidity and mortality. This review covers the mechanisms and indicators of malnutrition in ARF cases and the types of nutritional support that may be used.

    2014-01-01

    Severe acute malnutrition (SAM) is associated with increased severity of common infectious diseases, and death amongst children with SAM is almost always as a result of infection. The diagnosis and management of infection are often different in malnourished versus well-nourished children. The objectives of this brief are to outline the evidence underpinning important practical questions relating to the management of infectious diseases in children with SAM and to highlight research gaps. Overall, the evidence base for many aspects covered in this brief is very poor. The brief addresses antimicrobials; antipyretics; tuberculosis; HIV; malaria; pneumonia; diarrhoea; sepsis; measles; urinary tract infection; nosocomial Infections; soil transmitted helminths; skin infections and pharmacology in the context of SAM. The brief is structured into sets of clinical questions, which we hope will maximise the relevance to contemporary practice. PMID:25475887

    Gastrointestinal toxicity is uncommon among patients treated with angiotensin II receptor antagonists. A 58-year-old man presented with nausea, vomiting and constant pain in the epigastrium that radiated to the flanks. He received treatment with valsartan (160 mg daily) for hypertension. The clinical, biochemical and radiological findings were compatible with a diagnosis of acute pancreatitis. After the patient achieved a clinical and biochemical recovery, the valsartan therapy was started again. Six weeks later, he returned to the hospital with an attack of pancreatitis. Subsequently, he returned with repeated attacks of pancreatitis twice, and the valsartan was discontinued. Ten months after the treatment, the patient had no complaints. When severe abdominal symptoms occur for no apparent reason during treatment with valsartan, a diagnosis of pancreatitis should be considered.

  14. Acute liver failure in children.

    Squires, Robert H

    2008-05-01

    Acute liver failure (ALF) in children differs from that observed in adults in both the etiologic spectrum and the clinical picture. Children, particularly very young ones, do not demonstrate classical features of encephalopathy and the definition of ALF has been revised to include patients with advanced coagulopathy, regardless of mental status. A significant number of these children will go on to require transplant or die. Etiologies vary by age with metabolic and infectious diseases prominent in the first year of life and acetaminophen overdose and Wilson's disease occurring in adolescents. In almost 50% of cases, however, the child has an indeterminate cause for ALF. Management requires a multidisciplinary approach and is directed at establishing the etiology where possible and monitoring, anticipating, and managing the multisystem complications that occur in children with ALF. Overall, short-term outcomes are better in children than adults but are dependent upon the degree of encephalopathy and diagnosis.

    The objective of this article is to provide updates on acute pancreatitis in children regarding the imaging findings, causes, and complications based on a review of the current studies in the pediatrics literature. We discuss the epidemiology of acute pancreatitis, the role of imaging and imaging findings in the diagnosis of acute pancreatitis, and the causes and complications of acute pancreatitis. The incidence of acute pancreatitis is increasing in children. Imaging plays an important role in the diagnosis of acute pancreatitis because imaging findings can be used to establish the cause of acute pancreatitis, evaluate for complications of acute pancreatitis, and possibly predict the course of the disease.

  19. Microparticles and acute lung injury.

    The pathophysiology of acute lung injury (ALI) and its most severe form, acute respiratory distress syndrome (ARDS), is characterized by increased vascular and epithelial permeability, hypercoagulation and hypofibrinolysis, inflammation, and immune modulation. These detrimental changes are orchestrated by cross talk between a complex network of cells, mediators, and signaling pathways. A rapidly growing number of studies have reported the appearance of distinct populations of microparticles (MPs) in both the vascular and alveolar compartments in animal models of ALI/ARDS or respective patient populations, where they may serve as diagnostic and prognostic biomarkers. MPs are small cytosolic vesicles with an intact lipid bilayer that can be released by a variety of vascular, parenchymal, or blood cells and that contain membrane and cytosolic proteins, organelles, lipids, and RNA supplied from and characteristic for their respective parental cells. Owing to this endowment, MPs can effectively interact with other cell types via fusion, receptor-mediated interaction, uptake, or mediator release, thereby acting as intrinsic stimulators, modulators, or even attenuators in a variety of disease processes. This review summarizes current knowledge on the formation and potential functional role of different MPs in inflammatory diseases with a specific focus on ALI/ARDS. ALI has been associated with the formation of MPs from such diverse cellular origins as platelets, neutrophils, monocytes, lymphocytes, red blood cells, and endothelial and epithelial cells. Because of their considerable heterogeneity in terms of origin and functional properties, MPs may contribute via both harmful and beneficial effects to the characteristic pathological features of ALI/ARDS. A better understanding of the formation, function, and relevance of MPs may give rise to new promising therapeutic strategies to modulate coagulation, inflammation, endothelial function, and permeability either through

    An acute inhalation chamber study of 42 college students was performed to investigate the relation between exposure to 0, 75, and 150 ppm of toluene and changes in central nervous system function and symptoms. Paid subjects were exposed for seven hours over three days. Verbal and visual short term memory (Sternberg, digit span, Benton, pattern memory); perception (pattern recognition); psychomotor skill (simple reaction time, continuous performance, digit symbol, hand-eye coordination, finger tapping, and critical tracking); manual dexterity (one hole); mood (profile of mood scales (POMS]; fatigue (fatigue checklist); and verbal ability were evaluated at 0800, 1200, and 1600 hours. Voluntary symptoms and observations of sleep were collected daily. An analysis of variance and test for trend was performed on the difference and score for each concentration reflecting an eight hour workday where each subject was their own control. A 3 x 3 Latin square study design evaluated toluene effects simultaneously, controlling for learning across the three days and the solvent order. Intersubject variation in solvent uptake was monitored in breath and urine. A 5-10% decrement in performance was considered significant if it was consistent with a linear trend at p less than 0.05. Adverse performance at 150 ppm toluene was found at 6.0% for digit span, 12.1% for pattern recognition (latency), 5.0% for pattern memory (number correct), 6.5% for one hole, and 3.0% for critical tracking. The number of headaches and eye irritation also increased in a dose response manner. The greatest effect was found for an increasing number of observations of sleep. Overall, no clear pattern of neurobehavioural effects was found consistent with the type 1 central nervous system as classified by the World Health Organisation. Subtle acute effects, however, were found just below and above the ACGIH TLV of 100 ppm toluene, supporting the position that the guideline be lowered since the biological

  1. Basics of acute stroke treatment

    Acute stroke presents an emergency that requires immediate referral to a specialized hospital, preferably with a stroke unit. Disability and mortality are reduced by 30% in patients treated in stroke units compared to those treated on regular wards, even if a specialized team is present on the ward. Systolic blood pressure may remain high at 200-220 mmHg in the acute phase and should not be lowered too quickly. Further guidelines for basic care include: optimal O 2 delivery, blood sugar levels below 100-150 mg%, and lowering body temperature below 37.5 C using physical means or drugs. Increased intracranial pressure should be treated by raising the upper body of the patient, administration of glycerol, mannitol, and/or sorbitol, artificial respiration, and special monitoring of Tris buffer. Decompressive craniectomy may be considered in cases of ''malignant'' media stroke and expansive cerebellar infarction. Fibrinolysis is the most effective stroke treatment and is twice as effective in the treatment of stroke than myocardial infarction. Fibrinolysis may be initiated within 3 h of a stroke in the anterior circulation. If a penumbra is detectable by ''PWI-DWI mismatch MRI,'' specialized hospitals may perform fibrinolysis up to 6 h after symptom onset. In cases of stroke in the basilar artery, fibrinolysis may be performed even later after symptom onset. Intra-arterial fibrinolysis is performed in these cases using rt-PA or urokinase. Follow-up treatment of stroke patients should not only address post-stroke depression and neuropsychological deficits, but also include patient education about risk factors such as high blood pressure, diabetes mellitus, and cardiac arrhythmias.

    Piracetam has neuroprotective and antithrombotic effects that may help to reduce death and disability in people with acute stroke. This is an update of a Cochrane Review first published in 1999, and previously updated in 2006 and 2009. To assess the effects of piracetam in acute, presumed ischaemic stroke. We searched the Cochrane Stroke Group Trials Register (last searched 15 May 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 2), MEDLINE (1966 to May 2011), EMBASE (1980 to May 2011), and ISI Science Citation Index (1981 to May 2011). We also contacted the manufacturer of piracetam to identify further published and unpublished studies. Randomised trials comparing piracetam with control, with at least mortality reported and entry to the trial within three days of stroke onset. Two review authors extracted data and assessed trial quality and this was checked by the other two review authors. We contacted study authors for missing information. We included three trials involving 1002 patients, with one trial contributing 93% of the data. Participants' ages ranged from 40 to 85 years, and both sexes were equally represented. Piracetam was associated with a statistically non-significant increase in death at one month (approximately 31% increase, 95% confidence interval 81% increase to 5% reduction). This trend was no longer apparent in the large trial after correction for imbalance in stroke severity. Limited data showed no difference between the treatment and control groups for functional outcome, dependence or proportion of patients dead or dependent. Adverse effects were not reported. There is some suggestion (but no statistically significant result) of an unfavourable effect of piracetam on early death, but this may have been caused by baseline differences in stroke severity in the trials. There is not enough evidence to assess the effect of piracetam on dependence.

    Full Text Available Alcohol consumption is customary in most cultures and alcohol abuse is common worldwide. For example, more than 50% of Americans consume alcohol, with an estimated 23.1% of Americans participating in heavy and/or binge drinking at least once a month. A safe and effective therapy for alcoholic liver disease (ALD in humans is still elusive, despite significant advances in our understanding of how the disease is initiated and progresses. It is now clear that acute alcohol binges not only can be acutely toxic to the liver, but also can contribute to the chronicity of ALD. Potential mechanisms by which acute alcohol causes damage include steatosis, dysregulated immunity and inflammation and altered gut permeability. Recent interest in modeling acute alcohol exposure has yielded new insights into potential mechanisms of acute injury, that also may well be relevant for chronic ALD. Recent work by this group on the role of PAI-1 and fibrin metabolism in mediating acute alcohol-induced liver damage serve as an example of possible new targets that may be useful for alcohol abuse, be it acute or chronic.

    Diagnosis of bacterial acute rhinosinusitis is difficult. Several attempts have been made to clarify the diagnostic criteria. Inflammatory biomarkers are easily obtainable variables that could shed light on both the pathophysiology and diagnosis of bacterial acute rhinosinusitis. The purpose of this review article is to assess literature concerning the course of inflammatory biomarkers during acute rhinosinusitis and the use of inflammatory biomarkers in diagnosing bacterial acute rhinosinusitis. We included C-reactive protein, erythrocyte sedimentation rate, white blood cell counts, procalcitonin, and nasal nitric oxide in this review and found that especially elevated C-reactive protein and erythrocyte sedimentation rate are related to a higher probability of a bacterial cause of acute rhinosinusitis. Still, normal levels of these two biomarkers are quite common as well, or the levels can be heightened even during viral respiratory infection without suspicion of bacterial involvement. Elevated levels of C-reactive protein or erythrocyte sedimentation rate support diagnosis of bacterial acute rhinosinusitis, but due to a lack of sensitivity, they should not be used to screen patients for bacterial acute rhinosinusitis.

    The results of surgical treatment of 184 patients for obstructive jaundice and an acute cholangitis in choledocholithiasis were analyzed. Acute cholangitis was diagnosed in 62 (33.7%) patients. Sensitivity of a Tokyo Guidelines (2013)--TG 13 criteria for diagnosis and estimation of the course severity of an acute cholangitis was studied. Dynamics of postoperative laboratory parameters was studied. There was established, that occurrence of obturation jaundice and cholangitis coincides with pronounced hepatic function disorders, which are preserved after a bile outflow restoration also, and changes in peripheral blood. Severity of inflammatory reaction reflects hematological indices, the most informative of which is an intoxication index.

    Acute abdominal pain is a common clinical condition. Clinical signs and symptoms can be difficult to interpret, and diagnostic imaging may help to identify intra-abdominal disease. Conventional X-ray, ultrasound (US) and computed tomography (CT) of the abdomen vary in usability between common surgical causes of acute abdominal pain. Overall, conventional X-ray cannot confidently diagnose or rule out disease. US and CT are equally trustworthy for most diseases. US with subsequent CT may enhance diagnostic precision. Magnetic resonance seems promising for future use in acute abdominal imaging.

    Left-sided valvular lesions are commonly associated with acute and chronic coronary syndromes. Ischemic mitral regurgitation is well described in the literature. We report a case of acute ischemic right-sided valvular disease in which the presenting symptom of an infarction was severe tricuspid regurgitation. This rare entity is usually caused by distortion of the valve apparatus due to underlying wall motion abnormalities. In conclusion, tricuspid regurgitation is an important yet uncommon presentation of acute ischemia that requires a high degree of suspicion for diagnosis.

    Post surgical pain is a continuing major medical challenge despite all the advances in understanding acute pain and the development of new modalities of pain management. Since 1985 when the first acute pain service (APS) was started, many organizations initiated APS protocols and guidelines and it became mandatory to have an APS in all major acute care centers. This review focuses on the stages of development of APS and the challenges of postoperative pain management to provide optimal analgesia. Further clinical studies are required to determine best medication regimen for post-operative pain management.

  12. Oncoprotein E2A-Pbx1 immortalizes a myeloid progenitor in primary marrow cultures without abrogating its factor-dependence.

    Kamps, M P; Wright, D D

    1994-11-01

    E2A-PBX1 is a chimeric homeobox oncogene formed by the t(1;19) translocation of human pre-B cell acute lymphoblastic leukemia (ALL). In a previous study, we found that retroviral expression of E2A-Pbx1 in the marrow of reconstituted mice induced the formation of acute myeloid leukemia (AML) in vivo. Here, we report that E2A-Pbx1 can also immortalize myeloid progenitors in vitro, and that the outgrowth of immortalized myeloblasts is evident only in the presence of the myeloid lymphokine, granulocyte-macrophage colony stimulating factor (GM-CSF). When cultured in the presence of GM-CSF, responsive myeloblasts from normal marrow exhibit concurrent proliferation and differentiation, and undergo terminal differentiation into non-mitotic neutrophils and macrophages within 4 weeks. Infection of identical cultures with a retrovirus encoding E2A-Pbx1 produces a rapid outgrowth of myeloid progenitors that express high levels of E2A-Pbx1 protein. A small fraction of myeloblasts in each population exhibited limited differentiation to neutrophils, and all populations of myeloblasts retained a strict dependence on GM-CSF for both survival and proliferation. This data suggests that the function of E2A-Pbx1 in leukemias is to strongly retard differentiation without affecting growth-factor dependence.

    Full Text Available The research is aimed at the study of dynamic pathomorphological changes of choledoch and acute cholangitis development factors determined during the experiment. 36 rats of Wistar line were under trial. The main group consisted of 30 animals undergoing the open laparotomy, choledoch ligation and puncture modeling of acute cholangitis by E. coli culture in 1 х 108 CFU/ml concentration under general anesthesia. 6 healthy rats were included in the control group. Samples of general biliary duct under autopsy for pathomorphological study were taken on the 3rd, 7th, 14th, 21st and 30th day. In panoramic samples colored by hematoxilin and eozin the degree of dystrophic, necrobiotic, hemodynamic, inflammatory and atrophic manifestations’ changes were studied. Average depth of choledoch wall and height of its epithelial lining were morphometrically estimated. Collagen of the IV type as well as expressing receptors to CD34 were defined with the help of monoclonal antibodies in choledoch epithelial cells of basal membranes and choledoch vessels endotheliocytes. In choledoch, enhancement of edema and inflammatory infiltration by lymphoplasmocytic elements with the admixture of neutrofils with granulation tissue was detected from the 3rd up to the 30th day of the experiment. From the 14th day formation of bile clots of blood was detected in choledoch clearance, part of which was locked to its de-epitheliolized internal surface. According to morphometrical study data, choledoch wall depth increased from 261.1 ± 3.13 µm on the 3rd day to 572.5 ± 3.42 µm on the 30th day of the experiment. Mucosa membrane has lost its folding on the 14th day, epitheliocytes flattening was replaced by their destruction with fragments rejection into the duct lumen by the 30th day of the experiment.

    Inflammatory periodontal diseases are highly prevalent, although most of these diseases develop and progress slowly, often unnoticed by the affected individual. However, a subgroup of these diseases include aggressive and acute forms that have a relatively low prevalence but show a rapid-course, high rate of progression leading to severe destruction of the periodontal tissues, or cause systemic symptoms that often require urgent attention from healthcare providers. Aggressive periodontitis is an early-onset, destructive disease that shows a high rate of periodontal progression and distinctive clinical features. A contemporary case definition of this disease is presented. Population studies show that the disease is more prevalent in certain geographic regions and ethnic groups. Aggressive periodontitis is an infectious disease, and recent data show that in affected subjects the subgingival microbiota is composed of a mixed microbial infection, with a wide heterogeneity in the types and proportions of microorganisms recovered. Furthermore, there are significant differences in the microbiota of the disease among different geographic regions and ethnicities. There is also evidence that the Aggregatibacter actinomycetemycomitans-JP2 clone may play an important role in the development of the disease in certain populations. The host response plays an important role in the susceptibility to aggressive periodontitis, where the immune response may be complex and involve multiple mechanisms. Also, genetic factors seem to play an important role in the pathogenesis of this disease, but the mechanisms of increased susceptibility are complex and not yet fully understood. The available data suggest that aggressive periodontitis is caused by mutations either in a few major genes or in multiple small-effect genes, and there is also evidence of gene-gene and gene-environment interaction effects. Diagnostic methods for this disease, based on a specific microbiologic, immunologic or

    Full Text Available History of Present Illness: A 34-year-old HIV positive female presented to the emergency department with a three-week history of swollen, painful gums. She had difficulty eating and chewing, along with aches and general malaise. The patient was an everyday smoker and was not taking any antiretroviral medication. Significant findings: Physical examination revealed inflamed gingiva, ulceration, and soft tissue necrosis (Image 1 along with mandibular lymphadenopathy (not shown. Given her symptoms, poor oral care, and her immunocompromised state, she was given a diagnosis of Acute Necrotizing Ulcerative Gingivitis (ANUG or Vincent’s Angina. Discussion: Acute Necrotizing Ulcerative Gingivitis (ANUG, Vincent’s Angina, or Trench Mouth is the only periodontal disease in which bacteria invade non-necrotic tissue. The etiology is usually secondary to fusobacteria and spirochete overgrowth of bacteria which is normally present in the oral cavity. HIV infection, previous necrotizing gingivitis, poor oral hygiene, malnutrition, smoking, and stress are predisposing factors. Antibiotics and improved nutrition have significantly decreased the incidence of ANUG. The prevalence of ANUG among HIV infected patients varies from 4.3% to 16.0%. ANUG is 20.8 times more likely to be seen in AIDS patients with CD4 counts less than 200 cells/mm3. In developing countries, like those in Sub-Saharan Africa, incidence of ANUG is increasing among children with a prevalence as high as 23% in children under 10 years of age.1 Treatment for ANUG is multifactorial. Patients need good debridement under anesthesia so dental referral is imperative. Pain control with Ibuprofen or low dose opioids is indicated. Oral hygiene instructions include Chlorhexidine 0.12% twice daily, proper nutrition, appropriate fluid intake, and smoking cessation. For signs of systemic involvement, the recommended antibiotics are Amoxicillin and Metronidazole.2 If left untreated, ANUG may lead to rapid

    Purpose: Angioplasty effectively relieves coronary artery stenosis but is often followed by restenosis. Endovascular radiation (β or γ) at the time of angioplasty prevents restenosis in a large proportion of vessels in swine (short term) and humans (short and long term). Little information is available about the effects of this radiation exposure beyond the wall of the coronary arteries. Methods and Materials: Samples were obtained from 76 minipigs in the course of several experiments designed to evaluate endovascular brachytherapy: 76 of 114 coronary arteries and 6 of 12 iliac arteries were exposed to endovascular radiation from 32 P sources (35 Gy at 0.5 mm from the intima). Two-thirds of the vessels had angioplasty or stenting. The vessels were systematically examined either at 28 days or at 6 months after radiation. Results: We found an unexpected lesion: acute necrotizing vasculitis in arterioles located ≤2.05 mm from the target artery. It was characterized by fibrinoid necrosis of the wall, often associated with lymphocytic exudates or thrombosis. Based on the review of perpendicular sections of tissue samples, the arterioles had received between 6 and 40 Gy. This arteriolar vasculitis occurred at 28 days in samples from 51% of irradiated coronary arteries and 100% of irradiated iliac arteries. By 6 months, the incidence of acute vasculitis decreased to 24% around the coronary arteries. However, at that time, healing vasculitis was evident, often with luminal narrowing, in 46% of samples. Vasculitis was not seen in any of 44 samples from unirradiated vessels (0%) and had no relation to angioplasty, stenting, or their sequelae. This radiation-associated vasculitis in the swine resembles the localized lymphocytic vasculitis that we have reported in tissues of humans exposed to external radiation. On the other hand, it is quite different from the various types of systemic vasculitis that occur in nonirradiated humans. Conclusion: Endoarterial brachytherapy

    The role of liver transplantation (LT) in acute liver failure (ALF) complicated by severe acute pancreatitis is still unclear. We here report a case of deceased-donor LT for idiopathic ALF accompanied by severe acute pancreatitis. A 58-year-old man with no history of liver disease presented with idiopathic ALF and acute pancreatitis. After careful consideration, he received a liver from a deceased donor. Following surgery, the patient's liver function rapidly reverted to normal level and the acute pancreatitis simultaneously subsided. The patient later developed a pancreatic pseudocyst, which was treated successfully with combination interventional radiology. LT can be considered for ALF associated with severe acute pancreatitis if there is no clinical evidence of an absolute contraindication for organ transplantation, such as systemic or local infection. Moreover, we recommend a close follow-up by ultrasonography to allow early detection and treatment of pancreatic pseudocysts following surgery. 2016 BMJ Publishing Group Ltd.

    Full Text Available Abstract Background Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. Case presentation We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis. He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. Conclusion Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal function

    Basile, David P.; Anderson, Melissa D.; Sutton, Timothy A.

    2014-01-01

    Acute kidney injury (AKI) is the leading cause of nephrology consultation and is associated with high mortality rates. The primary causes of AKI include ischemia, hypoxia or nephrotoxicity. An underlying feature is a rapid decline in GFR usually associated with decreases in renal blood flow. Inflammation represents an important additional component of AKI leading to the extension phase of injury, which may be associated with insensitivity to vasodilator therapy. It is suggested that targeting the extension phase represents an area potential of treatment with the greatest possible impact. The underlying basis of renal injury appears to be impaired energetics of the highly metabolically active nephron segments (i.e., proximal tubules and thick ascending limb) in the renal outer medulla, which can trigger conversion from transient hypoxia to intrinsic renal failure. Injury to kidney cells can be lethal or sublethal. Sublethal injury represents an important component in AKI, as it may profoundly influence GFR and renal blood flow. The nature of the recovery response is mediated by the degree to which sublethal cells can restore normal function and promote regeneration. The successful recovery from AKI depends on the degree to which these repair processes ensue and these may be compromised in elderly or CKD patients. Recent data suggest that AKI represents a potential link to CKD in surviving patients. Finally, earlier diagnosis of AKI represents an important area in treating patients with AKI that has spawned increased awareness of the potential that biomarkers of AKI may play in the future.

    Full Text Available We examined 1824 patients with diphtheria treated in Clinical Infectious Diseases Hospital Botkin (St. Petersburg in 1993 – 1994, and more than 500 patients referred to the clinic with a diagnosis of «angina». Based on published data and our own research observations investigated the etiology of acute tonsillitis. Bacterial tonsillitis should be treated with antibiotics, and this is important aetiological interpretation of these diseases.

    Exposure to acute hypoxia is associated with changes in body fluid homeostasis and plasma volume (PV). This study compared a dye dilution technique using Evans' blue (PV[Evans']) with a carbon monoxide (CO) rebreathing method (PV[CO]) for measurements of PV in ten normal subjects at sea level...... and again 24 h after rapid passive ascent to high altitude (4,350 m). Hypobaric hypoxia decreased arterial oxygen saturation to 79 (74-83)% (mean with 95% confidence intervals). The PV(Evans') remained unchanged from 3.49 (3.30-3.68) l at sea level to 3.46 (3.24-3.68) l at high altitude. In contrast PV......(Evans') and PV(CO) increased from 1.04 (0.99-1.09) at sea level to 1.15 (1.06-1.24) at high altitude (P hypoxia-induced changes in PV. The mechanism responsible for the bias remains unknown, but it is suggested that the results may...

  4. Acute radiation syndrome in human

    The combination of the different types of irradiation dramatically changes the clinical course of acute radiation syndrome (ARS) in the case of short term exposure. The recent experience has been compared mostly with the data on the atomic bomb victims in Hiroshima and Nagasaki. The comparison of the injuries from different radiation exposures resulted in the possibility to receive summarized data and the actual basis of the observed difference. The situation with total relatively uniform irradiation is observed when human position is at long distance from powerful radiation sources or when he changes his position, as seen in atomic bomb survivors, the results of nuclear weapon tests and the patients in the Chernobyl accident. This is connected with the ARS of bone, marrow and intestine. The situation characterized by the clinical signs of the large area of skin and mucosa injuries was observed in nuclear weapon tests and the Chernobyl accident. In the case of the more localized and less severe beta injuries of skin and mucosa, the long term effects may be important. The majority of accidents in peaceful period are related to the uneven exposure from near sources, and the situation of the combination of external and internal irradiation is related to uneven irradiation and the predominance of internal exposure.

    Fabrega, H; Nutini, H

    1994-12-01

    In rural Tlaxcala, Mexico, the sudden and unexpected death of infants and young children was a relatively common occurrence during the time when this study was conducted. Not surprisingly, the deaths constituted major social tragedies and operated as psychological traumas to the family, especially the parents. Acute grief reactions inevitably resulted and these were suffused with bodily and psychological disturbances of different types, some of which were handled in the society as illness. The article grows out of a longitudinal study about these tragedies to families of the region. Attention is given to the grief reactions of parents, with special emphasis placed on psychological and behavioral manifestations. Of particular interest is the way local, cultural symbols pertaining to the cause of the deaths, which involved the malevolent attack of blood-sucking witches, were configured in the verbalizations and behavioral reactions that comprised the grief reactions. Details of the way symbols entered into the construction of meaningful accounts of the tragedies during the ordeal of the grief reactions are discussed and analyzed. Although the manifestations of grief could be said to have clinical, psychiatric implications, it is the way these manifestations served to explain the tragedies, in the process regulating and restoring social relations, that is given principal attention. A description of one mother's grief reaction is provided as a case illustration.

  6. Acute diverticulitis and surgical treatment.

    2018-04-01

    Diverticulitis is a common condition in industrialized countries and an important cause of hospital admissions. Its growing trend is a challenge for the surgeons who perform emergency surgery, because approximately 15-25% of the patients will require surgery, being the surgical management of complicated acute diverticulitis controversial. The past decade has seen a paradigm shift in the treatment of sigmoid diverticulitis based on new epidemiological studies and refinement of surgical techniques that has produced a reassessment of our guidelines. CT imaging and sepsis scores allows to stratify the patients and better define the therapeutic strategies in each case. Special considerations must also be made for patients with a high surgical risk, such as immunosuppressed ones. The recommendations to perform surgery after two episodes of uncomplicated diverticulitis have been re-evaluated and the belief that new episodes may be complicated and associated with high morbidity and mortality has been rejected, since the clinical manifestations of this disease are usually defined by the first attack. In complicated cases, more patients can be treated with resection and primary anastomosis with or without an associated stoma, whose reversal rate is much higher than that of a Hartmann's procedure. Likewise, laparoscopic surgery performing a peritoneal lavage and drainage without associated resection may have an increasing role in the management of these patients, although with controversial results, having become laparoscopic colon resection the approach of choice for the treatment of this pathology in elective settings.

  7. MRI of acute cerebral infarction

    1989-01-01

    Sequential changes of magnetic resonance imaging (MRI) in sixteen patients with acute cerebral infarction are studied in comparison with the findings of computed tomography (CT). The sixteen patients were examined within 36 hours from the onset of syptoms on resistive type MRI (0.15T) using T1 weighted image (IR2000/500) and T2 weighted image (SE2000/80), and on CT. In general, large infarcted lesions of the cortexsubcortex seemed to be visualized earlier than small lesions of the basal ganglia and brainstem. In 8 patients, the infarcted lesions were detected on MRI earlier than on CT. For example, early detecting time within 12 hours were 2, 6, 7, and 10 hours after onset. In two patients of this group, lesions were detected on T2 weighted image earlier than on T1-weighted image. In two cases, small lesions of the brainstem were detected only on MRI. The size of abnormal findings gradually developed and reached a maximum on days 5 to 7 sequentially. The difference between infarction and perifocal edema was not clear even on MRI. The changes gradually subsided and assumed a stable size after about 2 months. Contrast enhancement effect was observed in four patients. In two of these cases, the signal intensity of T2-weighted imaging was decreased just at the region which was enhanced with contrast medium. MRI is useful for early diagnosis of ischemic cerebral infarction, and may eludidate some aspects of the pathophysiology of ischemic stroke.

    Hyperglycaemia in patients with Acute Coronary Syndrome (ACS)is common, and is an independent predictor of mortality and morbidity in patients both with and without diabetes mellitus. Hyperglycaemia may be a marker of pre-existing diabetes or glucose intolerance or may also represent a transient stress response mediated through the autonomic nervous system with release of adrenal corticosteroids and catecholamines. Several evidences suggest that an intensive control of hyperglycaemia results in a significant improvement of the adverse outcomes in the short and long term. In fact, an intensive metabolic treatment can counteract the negative effects of hyperglycaemia. However, the main difficulty to intensive glucose control in patients with ACS remains hypoglycaemia that is associated with an increased risk of mortality and myocardial re-infarction. No definitive data are available about the beneficial effects of insulin intensive treatment. Therefore, randomized multicenter clinical trials will be needed to definitively establish whether intensive glucose control will reduce the associated increased mortality rate and higher rates of complications in hospitalized ACS patients with hyperglycaemia.

  9. Immunomodulatory therapies for acute pancreatitis

    2014-01-01

    It is currently difficult for conventional treatments of acute pancreatitis (AP), which primarily consist of anti-inflammatory therapies, to prevent the progression of AP or to improve its outcome. This may be because the occurrence and progression of AP, which involves various inflammatory cells and cytokines, includes a series of complex immune events. Considering the complex immune system alterations during the course of AP, it is necessary to monitor the indicators related to immune cells and inflammatory mediators and to develop more individualized interventions for AP patients using immunomodulatory therapy. This review discusses the recent advances in immunomodulatory therapies. It has been suggested that overactive inflammatory responses should be inhibited and excessive immunosuppression should be avoided in the early stages of AP. The optimal duration of anti-inflammatory therapy may be shorter than previously expected (< 24 h), and appropriate immunostimulatory therapies should be administered during the period from the 3rd d to the 14th d in the course of AP. A combination therapy of anti-inflammatory and immune-stimulating drugs would hopefully constitute an alternative to anti-inflammatory drug monotherapy. Additionally, the detection of the genotypes of critical inflammatory mediators may be useful for screening populations of AP patients at high risk of severe infections to enable the administration of early interventions to improve their prognosis.

    1986-01-01

    Acute renal failure is a serious complication oif reconstructive aortoiliac surgery. The question was raised whether its etiology includes interaction between preoperative angiographic contrast medium and intra-operative clamping of the renal arteries. Renal arteries of 180 rats were bilaterally clamped 10 to 120 min and serum urea was determined from 3 h to 7 days later. In 35 rats 40 min clamping alone produced an increase in urea reaching a maximum 1 day later (median increase 70%). In 3 groups of 12 rats intravenous injection of the contrast medium metrizoate alone in doses 1, 2 and 3 g I/kg body-weight produced no significant increase in urea. Intravenous injection of the same doses to 3 groups of 10 rats each followed 1 h later by renal arterial occlusion for 40 min produced median urea increases one day later of 110, 130 and 170%, respectively, in the 3 groups. The increase was higher than that produced by contrast medium alone (p<0.01) or by renal artery clamping alone (p<0.05) indicating a potentiation of transient renal failure by the combination of contrast medium and renal arterial clamping.

    2012-01-01

    Full Text Available Acute lung injury carries a high burden of morbidity and mortality and is characterised by nonhydrostatic pulmonary oedema. The aim of this paper is to highlight the role of accurate quantification of extravascular lung water in diagnosis, management, and prognosis in “acute lung injury” and “acute respiratory distress syndrome”. Several studies have verified the accuracy of both the single and the double transpulmonary thermal indicator techniques. Both experimental and clinical studies were searched in PUBMED using the term “extravascular lung water” and “acute lung injury”. Extravascular lung water measurement offers information not otherwise available by other methods such as chest radiography, arterial blood gas, and chest auscultation at the bedside. Recent data have highlighted the role of extravascular lung water in response to treatment to guide fluid therapy and ventilator strategies. The quantification of extravascular lung water may predict mortality and multiorgan dysfunction. The limitations of the dilution method are also discussed.

    Acute pancreatitis is a fascinating disease. In the United States, the two most common etiologies of acute pancreatitis are gallstones and excessive alcohol consumption. The diagnosis of acute pancreatitis is made with a combination of history, physical examination, computed tomography scan, and laboratory evaluation. Differentiating patients who will have a benign course of their pancreatitis from patients who will have severe pancreatitis is challenging to the clinician. C-reactive protein, pro-calcitonin, and the Bedside Index for Severity of Acute Pancreatitis appeared to be the best tools for the early and accurate diagnosis of severe pancreatitis. Early laparoscopic cholecystectomy is indicated for patients with mild gallstone pancreatitis. For patients who are going to have a prolonged hospitalization, enteral nutrition is preferred. Total parenteral nutrition should be reserved for patients who cannot tolerate enteral nutrition. Prophylactic antibiotics are not indicated for patients with pancreatic necrosis. Surgical intervention for infected pancreatic necrosis should be delayed as long as possible to improve patient outcomes.

    Hypertriglyceridemia is a well known phenomenon of pregnancy occurring due to physiologic changes in sex hormone levels. Occasionally, it could lead to development of acute pancreatitis. Gestational hypertriglyceridemia-induced acute pancreatitis occurs in pregnant women usually with preexisting abnormalities of the lipid metabolism and is associated with additional diagnostic and therapeutic challenges related to hypertriglyceridemia and pregnancy. We present a case of the hypertriglyceridemia-induced acute pancreatitis in pregnant woman with no previous history of lipid abnormality and pregnancy as the only known triggering factor for hypertriglyceridemia. Hypertriglyceridemia-induced acute pancreatitis is a rare complication of pregnancy; however, it should be suspected in all pregnant patients admitted for nonobsteric abdominal pain.

    In recent years, magnetic resonance imaging (MRI) has become a valuable diagnostic tool for evaluation of acute abdominal pain in pregnancy. MRI offers an opportunity to identify the normal or inflamed appendix as well as a variety of other pathologic conditions that can masquerade clinically as acute appendicitis in pregnant women. Visualization of the normal appendix by MRI virtually excludes the diagnosis of acute appendicitis and may help reduce the negative laparotomy rate in this patient population. Here we discuss a comprehensive MRI protocol for evaluation of pregnant women with abdominal pain, focusing on the appearance and location of the normal and diseased appendix, and we describe an approach to diagnosing acute appendicitis and other conditions with MRI.

    Acute appendicitis is the most common surgical emergency in pregnancy. The incidence of appendicitis in pregnancy was one in 766 births. The preoperative diagnosis was correct in 75% of the cases. Because of considerable fetal loss after appendectomy during pregnancy in the first and second trimester, surgeons decide to use diagnostic imaging to prove the diagnosis. The American College of Radiology (ACR) approves of MR imaging of the pregnant patient in any trimester, including the first. In this case -30 years old, pregnant 12 week gestation, present with right lower quadrant abdominal pain. Acute appendicitis is suspected, because of positive Romberg and ilio-psoas sign and high WBC and CRP. After MR imaging the diagnosis of acute appendicitis was proved together with intrauterine gestation. Key words: Acute Appendicitis. MRI. Pregnancy. Fetal Loss [bg

  1. Acute-phase proteins: As diagnostic tool

    Directory of Open Access Journals (Sweden)

    Sachin Jain

    2011-01-01

    Full Text Available The varied reactions of the host to infection, inflammation, or trauma are collectively known as the acute-phase response and encompass a wide range of pathophysiological responses such as pyrexia, leukocytosis, hormone alterations, and muscle protein depletion combining to minimize tissue damage while enhancing the repair process. The mechanism for stimulation of hepatic production of acute-phase proteins is by proinflammatory cytokines. The functions of positive acute-phase proteins (APP are regarded as important in optimization and trapping of microorganism and their products, in activating the complement system, in binding cellular remnants like nuclear fractions, in neutralizing enzymes, scavenging free hemoglobin and radicals, and in modulating the host′s immune response. APP can be used as diagnostic tool in many diseases like bovine respiratory syncytial virus, prostate cancer, bronchopneumonia, multiple myeloma, mastitis, Streptococcus suis infection, starvation, or lymphatic neoplasia. Thus, acute-phase proteins may provide an alternative means of monitoring animal health.

    Full Text Available Endovascular therapy (EVT has gained vogue in the management of patients with acute stroke. Newer stent-retriever devices have led to better recanalization rates. In many centers, EVT is slowly being used as an add on to or in some instances, even as an alternative to intravenous tissue plasminogen activator (IV tPA. The publication of the results of the SYNTHESIS expansion, Interventional Management of Stroke III and Mechanical Retrieval Recanalization of Stroke Clots Using Embolectomy trials in 2013 has questioned the enthusiastic use of EVT in acute stroke. They demonstrate that EVT (using a variety of devices is no superior to IV tPA in the management of acute stroke. In the light of these controversial findings, we review the current status of EVT in the management of acute stroke.

    Di Somma, Salvatore; Magrini, Laura

    2015-08-01

    Acute heart failure is globally one of most frequent reasons for hospitalization and still represents a challenge for the choice of the best treatment to improve patient outcome. According to current international guidelines, as soon as patients with acute heart failure arrive at the emergency department, the common therapeutic approach aims to improve their signs and symptoms, correct volume overload, and ameliorate cardiac hemodynamics by increasing vital organ perfusion. Recommended treatment for the early management of acute heart failure is characterized by the use of intravenous diuretics, oxygen, and vasodilators. Although these measures ameliorate the patient's symptoms, they do not favorably impact on short- and long-term mortality. Consequently, there is a pressing need for novel agents in acute heart failure treatment with the result that research in this field is increasing worldwide.

    We report the case of a 31 year-old man diagnosed with an atypical acute leukemia difficult to characterize cytologically. The immunophenotyping identified a blastic population co-expressing myeloid, lymphoid B and lymphoid T markers suggesting the diagnosis of either a mixed phenotype acute leukemia (MPAL) or an early T-cell precursor acute lymphoblastic leukemia (ETP-ALL). Because of the poor prognosis linked to these leukemias, the patient benefited from chemotherapy targeting both myeloid and lymphoid components, followed by allogeneic hematopoietic stem cell transplantation. DNA-based techniques analyzing B and T-cell clonality identified partial rearrangements in immunoglobulin and TCR genes, allowing the monitoring of minimal residual disease. This observation highlights the difficulty to classify some atypical cases of acute leukemias. It emphasizes on the complementarity of cytomorphology, immunophenotyping by flow cytometry and molecular techniques in order to promptly characterize and treat these leukemias.

    2009-12-01

    Full Text Available Abstract Although acute pericarditis has charachteristic electrocardiographic (ECG findings that differentiate it from acute ST segment elevation myocardial infarction (MI; in certain cases diagnosis is somewhat difficult especially when the ECG reveals focal instead of diffuse changes and moreover when pericarditis is associated with an underlying myocarditis causing elevation of the cardiac biomarkers therefore increasing the difficulty in differentiating between both enteties. This is especially important because adverse lethal side effect can occur if thrombolytic therapy is administered for a patient with acute pericarditis, or if a diagnosis of transmural MI is missed. In this case report we are describing an 18 year old male patient who presented with an acute onset of severe chest pain associated with focal ECG changes and elevated cardiac enzymes mimicking transmural MI. This report aims to sensitize readers to this debate and create awareness among cardiologists and intensivists with both presentations and how to reach an accurate diagnosis.

    We report the case of a young man with sudden onset of diplopia after an upper respiratory tract infection. Based on the first radiological findings acute hemorrhagic leukoencephalitis, a variant of acute disseminated encephalomyelitis, was suspected and treatment with high dose intravenous dexamethasone was started but it was stopped for intolerance. The patient clinically worsened, developing gait instability, ataxia and ophthalmoplegia; brain MRI performed 20 days later showed severe progression of the disease with subependymal dissemination. After brain biopsy of the right temporal lesion the histological diagnosis was glioblastoma. These findings suggest that MRI features of acute hemorrhagic leukoencephalitis may dissimulate the diagnosis of diffuse glioma/glioblastoma. This case underscores the importance of considering diffuse glioma in the differential diagnosis of atypical signs and symptoms of acute hemorrhagic leukoencephalitis and underlines the relevant role of integrating neuroradiologic findings with neuropathology.

    Full Text Available Abstract Introduction Transfusion-related acute lung injury is emerging as a common cause of transfusion-related adverse events. However, awareness about this entity in the medical fraternity is low and it, consequently, remains a very under-reported and often an under-diagnosed complication of transfusion therapy. Case presentation We report a case of a 46-year old woman who developed acute respiratory and hemodynamic instability following a single unit blood transfusion in the postoperative period. Investigation results were non-specific and a diagnosis of transfusion-related acute lung injury was made after excluding other possible causes of acute lung injury. She responded to symptomatic management with ventilatory and vasopressor support and recovered completely over the next 72 hours. Conclusion The diagnosis of transfusion-related acute lung injury relies on excluding other causes of acute pulmonary edema following transfusion, such as sepsis, volume overload, and cardiogenic pulmonary edema. All plasma containing blood products have been implicated in transfusion-related acute lung injury, with the majority being linked to whole blood, packed red blood cells, platelets, and fresh-frozen plasma. The pathogenesis of transfusion-related acute lung injury may be explained by a "two-hit" hypothesis, involving priming of the inflammatory machinery and then activation of this primed mechanism. Treatment is supportive, with prognosis being substantially better than for most other causes of acute lung injury.

    Full Text Available Arantxa Mas, Josep MasipCritical Care Department, Consorci Sanitari Integral (CSI, Hospital Sant Joan Despí Moisès Broggi and Hospital General de l’Hospitalet, University of Barcelona, Barcelona, SpainAbstract: After the institution of positive-pressure ventilation, the use of noninvasive ventilation (NIV through an interface substantially increased. The first technique was continuous positive airway pressure; but, after the introduction of pressure support ventilation at the end of the 20th century, this became the main modality. Both techniques, and some others that have been recently introduced and which integrate some technological innovations, have extensively demonstrated a faster improvement of acute respiratory failure in different patient populations, avoiding endotracheal intubation and facilitating the release of conventional invasive mechanical ventilation. In acute settings, NIV is currently the first-line treatment for moderate-to-severe chronic obstructive pulmonary disease exacerbation as well as for acute cardiogenic pulmonary edema and should be considered in immunocompromised patients with acute respiratory insufficiency, in difficult weaning, and in the prevention of postextubation failure. Alternatively, it can also be used in the postoperative period and in cases of pneumonia and asthma or as a palliative treatment. NIV is currently used in a wide range of acute settings, such as critical care and emergency departments, hospital wards, palliative or pediatric units, and in pre-hospital care. It is also used as a home care therapy in patients with chronic pulmonary or sleep disorders. The appropriate selection of patients and the adaptation to the technique are the keys to success. This review essentially analyzes the evidence of benefits of NIV in different populations with acute respiratory failure and describes the main modalities, new devices, and some practical aspects of the use of this technique.

    Acute diverticulitis of the colon represents a significant burden for national health systems, in terms of direct and indirect costs. Past guidelines claimed that recurrent episodes (two or more) of diverticulitis need surgery, but revised guidelines recommend an individualized approach to patients after an attack of acute diverticulitis. For these reasons, conservative treatment has become the preferred choice after an episode of diverticulitis. Thus, significant efforts are now being focuse...

    The acute abdomen in pregnancy is a surgical emergency. Ectopic pregnancy and appendicitis are two causes of acute abdomen in pregnancy. Difficulties in correctly identifying the cause of the pain can be hazardous to the patient and care needs to be taken in obtaining a prompt and accurate diagnosis enabling the most appropriate management. The case presented here underlies the pathogenesis of the simultaneous existence of these two conditions in a patient.

    Objective: To evaluate the role of laparoscopic cholecystectomy in acute cholecystitis and establish the out-comes of this treatment modality at North Oakland Medical Centers. Methods: This was a retrospective analysis over a three-year period (January 1, 1994 to December 31, 1996), per-formed at a University-affiliated urban teaching hospital, North Oakland Medical Centers, Pontiac, Michigan. Five hundred and fifty-seven patients underwent surgical treatment for gallbladder disease; 88 patients had acute cholecystitis, and 469 patients had chronic cholecystitis. Acute cholecystitis patients underwent surgery within 72 hours of the onset of symptoms; the patient's selection for laparoscopic cholecystectomy or open cholecystectomy depended on severity of disease, comorbid factors and surgeon's preference. The parameters of age, gender, operating (OR) time, length of stay, complications, conversion rates from laparoscopic cholecystectomy to open cholecystectomy, and cost were compared in patients who underwent laparoscopic cholecystectomy and/or open cholecystectomy. Results: Patients chosen to undergo laparoscopic cholecystectomy for acute cholecystitis tended to be younger females. Patients treated with laparoscopic cholecystectomy for acute cholecystitis had shorter OR times and LOS compared to patients treated with open cholecystectomy for acute cholecystitis. Conversion rates (CR) were 22% in acute cholecystitis and 5.5% in chronic cholecystitis during the study period; CR diminished considerably between the first and third year. Complications were also lower in patients who underwent laparoscopic cholecystectomy vs. open cholecystectomy. Conclusions: Laparoscopic cholecystectomy appears to be a reliable, safe, and cost-effective treatment modality for acute cholecystitis; however, the surgical approach should be cautionary because of the spectrum of potential technical hazards. CR is improving as surgeons gain experience. PMID:10444011

    The authors present a case of enterobiasis of the appendix. Enterobius infection is an uncommon cause of acute appendicitis. Preoperative diagnosis of pinworm infestation is almost impossible unless there is a strong clinical suspicion. Parasites may produce symptoms which resemble acute appendicitis. Careful observation of the appendix stump may lead to intraoperative diagnosis of enterobiasis. A quick diagnosis and appropriate treatment may prevent future complications.

    Acute generalized exanthematous pustulosis (AGEP) is an acute sterile pustular eruption most commonly induced by medications. We present a case of AGEP with erythroderma following use of midodrine in a 58-year-old man. Although antibiotics are most commonly implicated in AGEP, we emphasize that nonantibiotic agents also may cause AGEP, which often manifests after a longer time interval compared to antibiotic-associated AGEP.
