    Recurrent chromosomal abnormalities and gene mutations detected at the time of diagnosis of acute myeloid leukemia (AML) are associated with particular disease features, treatment response and survival of AML patients, and are used to denote specific disease entities in the World Health Organization classification of myeloid neoplasms and acute leukemia. However, large studies that integrate cytogenetic and comprehensive mutational information are scarce. We created a comprehensive oncoprint of mutations associated with recurrent cytogenetic findings by combining the information on mutational patterns of 80 cancer- and leukemia-associated genes with cytogenetic findings in 1603 adult patients with de novo AML. We show unique differences in the mutational profiles among major cytogenetic subsets, identify novel associations between recurrent cytogenetic abnormalities and both specific gene mutations and gene functional groups, and reveal differences in cytogenetic and mutational features between patients younger than 60 years and those aged 60 years or older. The identified associations between cytogenetic and molecular genetic data may help guide mutation testing in AML, and result in more focused application of targeted therapy in patients with de novo AML.

    Full Text Available Objective: Treatment of acute lymphoblastic leukemia (ALL in adults focuses on the initial assessment of the prognostic relevant cytogenetic features as well as a response-guided therapy based on molecular data. We examined the importance of molecular-cytogenetic abnormalities for complete remission (CR rates and the overall survival (OS in adult ALLs.Materials and Methods: Conventional cytogenetics and fluorescence in situ hybridization were performed on bone marrow cells from 33 newly-diagnosed ALL adults. Two karyotype categories [standard- risk group- normal karyotype, hyperdiplody and other structural aberrations, and high-risk group-t(11q23/MLL, t(9;22/bcr-abl, t(1;19, t(8;14, C-MYC and complex karyotype] and the biologically and clinically relevant ALL ploidy subgroups were prospectively defined.Results: Chromosomal abnormalities were found in 52% of the cases with a high rate of poor-risk translocations - t(9;22, t(8q24, t(11q23, t(1;19. The total CR rate was 67% and the median time for achievement 2.33 months. Male sex, an age below 35 years and the absence of high risk translocations might have contributed to the high CR rates. Female patients, hyperdiplody, low white blood cells (WBC, and random cytogenetic aberrations had the longest OS. OS, 3- and 5-years survival periods were significantly shorter for poor-risk than standard risk group (p=.015, p=.001 and p=.005, respectively.Conclusion: This study emphasizes the lack of influence of cytogenetic aberrations on the CR and the time to achieve CR. However, our observations show that these aberrations are an independent prognostic factor in adult ALL - they allow predicting therapy resistance and the OS time after intensetreatment.

    The spectrum of chromosomal abnormality associated with leukemogenesis of acute myeloid leukemia (AML) is broad and heterogeneous when compared to chronic myeloid leukemia and other myeloid neoplasms. Recurrent chromosomal translocations such as t(8;21), t(15;17), and inv(16) are frequently detected, but hundreds of other uncommon chromosomal aberrations from AML also exist. This chapter discusses 22 chromosomal abnormalities that are common structural, numerical aberrations, and other important but infrequent (less than 1 %) translocations emphasized in the WHO classification. Brief morphologic, cytogenetic, and clinical characteristics are summarized, so as to provide a concise reference to cancer cytogenetic laboratories. Morphology based on FAB classification is used together with the current WHO classification due to frequent mentioning in a vast number of reference literatures. Characteristic chromosomal aberrations of other myeloid neoplasms such as myelodysplastic syndrome and myeloproliferative neoplasm will be discussed in separate chapters-except for certain abnormalities such as t(9;22) in de novo AML. Gene mutations detected in normal karyotype AML by cutting edge next generation sequencing technology are also briefly mentioned.

    BACKGROUND: There is a paucity of data regarding hematological abnormalities in adults with Down\\'s syndrome (DS). AIMS: We aimed to characterize hematological abnormalities in adult patients with DS and determine their long-term significance. METHODS: We retrospectively studied a cohort of nine DS patients referred to the adult hematology service in our institution between May 2001 and April 2008. Data collected were: full blood count (FBC), comorbidities, investigations performed, duration of follow-up and outcome to most recent follow-up. RESULTS: Median follow-up was 26 months (9-71). Of the nine patients, two had myelodysplastic syndrome (MDS) at presentation. Of these, one progressed, with increasing marrow failure, and requiring support with transfusions and gCSF. The remaining eight patients, with a variety of hematological abnormalities including leukopenia, macrocytosis, and thrombocytopenia, had persistently abnormal FBCs. However there was no evidence of progression, and no patient has evolved to acute myeloid leukemia (AML). CONCLUSIONS: MDS is a complication of DS and may require supportive therapy. However, minor hematological abnormalities are common in adult DS patients, and may not signify underlying marrow disease.

    Diagnostic karyotype provides the framework for risk-stratification schemes in acute myeloid leukemia (AML); however, the prognostic significance of many rare recurring cytogenetic abnormalities remains uncertain. We studied the outcomes of 5876 patients (16-59 years of age) who were classified into 54 cytogenetic subgroups and treated in the Medical Research Council trials. In multivariable analysis, t(15;17)(q22;q21), t(8;21)(q22;q22), and inv(16)(p13q22)/t(16;16)(p13;q22) were the only abnormalities found to predict a relatively favorable prognosis (P < .001). In patients with t(15;17) treated with extended all-trans retinoic acid and anthracycline-based chemotherapy, additional cytogenetic changes did not have an impact on prognosis. Similarly, additional abnormalities did not have a significant adverse effect in t(8;21) AML; whereas in patients with inv(16), the presence of additional changes, particularly +22, predicted a better outcome (P = .004). In multivariable analyses, various abnormalities predicted a significantly poorer outcome, namely abn(3q) (excluding t(3;5)(q25;q34)), inv(3)(q21q26)/t(3;3)(q21;q26), add(5q)/del(5q), -5, -7, add(7q)/del(7q), t(6;11)(q27;q23), t(10;11)(p11 approximately 13;q23), other t(11q23) (excluding t(9;11)(p21 approximately 22;q23) and t(11;19)(q23;p13)), t(9;22)(q34;q11), -17, and abn(17p). Patients lacking the aforementioned favorable or adverse aberrations but with 4 or more unrelated abnormalities also exhibited a significantly poorer prognosis (designated "complex" karyotype group). These data allow more reliable prediction of outcome for patients with rarer abnormalities and may facilitate the development of consensus in reporting of karyotypic information in clinical trials involving younger adults with AML. This study is registered at http://www.isrctn.org as ISRCTN55678797 and ISRCTN17161961.

    Acute myeloid leukaemia (AML) with 17p abnormalities (abn(17p)) carries a very poor prognosis due to high refractoriness to conventional chemotherapy, and allogeneic stem cell transplantation (allo-SCT) appears as the only potential curative option. To address outcomes after allo-SCT in patients with abn(17p), we retrospectively analysed de novo or secondary AML undergoing SCT between 2000 and 2013 from the EBMT registry. One hundred thirty-nine patients with confirmed abn(17p) have been selected. At the time of transplant, one hundred twenty-five were in first remission (CR1). Median age was 54 years old. Abn(17p) was associated with a monosomal karyotype in 83% of patients, complex karyotype in 91%, monosomy 5 or 5q deletion (-5/5q-) in 55%, monosomy 7 (-7) in 39% and both -5/5q and -7 in 27%. Seventy-three patients (59%) had a reduced-intensity conditioning regimen. The 2-year overall survival (OS) and leukaemia-free survival (LFS) were 28 and 24%, respectively. The 2-year non-relapse mortality (NRM) was 15%, and 2-year relapse incidence (RI) was 61%. The cumulative incidence of grade II to IV acute graft-versus-host disease (GvHD) was 24% and that of chronic GvHD was 21%. In multivariate analysis, the presence of a -5/5q- in addition to abn(17p) was significantly and independently associated with worse OS, LFS and higher RI. Age and donor types did not correlate with outcome. Conditioning intensity was not statistically associated with OS, LFS and NRM when adjusted for patients' age. In contrast to the dismal prognosis reported for AML patients harbouring abn(17p) undergoing conventional chemotherapy, allogeneic SCT provides responses in about 25% of those patients transplanted in CR1.

    Bronchial thermoplasty (BT) is a novel treatment for severe asthma based on radiofrequency energy delivery to the larger airways. Although impressive radiological abnormalities have been reported, the incidence, pattern, and behavior over time of acute radiological abnormalities following BT are not well established. To assess the incidence pattern and behavior over time of acute radiological abnormalities following BT. This is a prospective, observational imaging study of severe asthma patients participating in the TASMA trial. Imaging of the lung (chest X-ray and/or computed tomography [CT]) was performed routinely before and directly after BT, within 6 weeks and at 6 months' follow-up. Thirty-four chest X-rays were performed within bronchial occlusions (63%), and bronchial dilatations (19%). No bronchoscopic intervention was needed. At 6 months' follow-up, in a single patient, high-resolution chest CT showed a focal bronchiectasis in a single airway. There is a high incidence of acute radiological abnormalities after BT. Four distinct radiological patterns can be identified on ULD chest CT, which resolve without clinical impact in virtually all cases. © 2017 The Author(s) Published by S. Karger AG, Basel.

    The study aims to elucidate the characteristics of post-stroke taste dysfunction in postmenopausal women. Taste function in 120 consecutive postmenopausal women with acute (sweetness, glacial acetic acid for sourness and quinine hemisulfate for bitterness. Detection and recognition thresholds were performed by the three-stimulus drop technique. Taste threshold values beyond two standard deviations of normal were considered "abnormal". For postmenopausal women after acute stroke, abnormal detection thresholds for the ability to taste sweetness, saltiness, sourness and bitterness were found in 33%, 21%, 35% and 30% of women, respectively, and abnormal recognition thresholds were found in 40%, 34%, 42% and 33% of women respectively. The taste dysfunction occurred ipsilaterally, contralaterally or bilaterally, and was not related to the side or location of the lesion. Large (>2 cm) lesions were more frequently associated with sweet and salty taste dysfunction than small lesions (pevaluation showed that the taste abnormality persisted in 8 (35%) patients. Taste perception abnormalities are common and often persistent in stroke patients. The dysfunction can occur ipsilaterally, contralaterally or bilaterally.

    Chromosomal abnormalities are present in bone marrow of approximately 50% of newly diagnostic acute nonlymphatic leukemia (ANLL) patients, but their etiologic significance, if any, is unclear. The frequency of environmental exposures, gathered by questionnaire from patients or relatives, was compared in 127 newly diagnosed ANLL patients with marrow abnormalities (AA) and 109 ANLL patients with cytogenetically normal marrow. These represented 73% of de novo patients treated at M. D. Anderson Hospital between 1976 and 1983. AA patients were more likely than NN patients to: report cytotoxic treatment for prior medical conditions, smoke cigarettes, drink alcoholic beverages, and work at occupations with possible exposure to mutagens. No statistically significant associations between aneuploidy and use of other tobacco, avocational exposure to chemicals or exposure to animals were present. Associations between specific abnormalities and prior cytotoxic therapy (deletion of chromosome 7), smoking (extra chromosome 8, inversion chromosome 16), and occupation at the time of diagnosis (translocation between chromosomes 8 and 21) were noted. No association between occupational exposure to benzene or ionizing radiation and the 6 most common chromosomal abnormalities in ANLL patients were noted, although these agents are known to be leukemogenic. Problems with interpreting the above associations, including the high nonresponse rate, a high proportion of surrogate respondents, and the large number of significance tests that were performed, are discussed. These results are consistent with those from previously reported series, and suggest that tumor-specific markers may be present for some exposures in this disease

    Full Text Available New onset of electrocardiographic (ECG abnormalities can occur after lung surgery due to the changes in the position of structures and organs in the chest cavity. The most common heart rhythm disorder is atrial fibrillation. So-called “pseudoischemic” ECG changes that mimic classic ECG signs of acute myocardial ischemia are also often noticed. We report the case of a 68-year-old male, with no prior cardiovascular disease, who underwent extensive surgical resection for lung cancer. On a second postoperative day, clinical and electrocardiographic signs of acute myocardial ischemia occurred. According to clinical course, diagnostic procedures, and therapeutic response, we excluded acute coronary syndrome. We concluded that physical lesion of the pericardium, caused by extended pneumonectomy with resection of the pericardium, provoked the symptoms and ECG signs that mimic acute coronary syndrome. Our final diagnosis was postpericardiotomy syndrome after extended pneumonectomy and further treatment with nonsteroidal anti-inflammatory drugs (NSAIDs was recommended. It is necessary to consider possibility that nature of ECG changes after extended pneumonectomy could be “pseudoischemic.”

    To investigate the MR characteristics of SONK-like (spontaneous osteonecrosis of the knee) subchondral abnormalities in the adult atraumatic knee and to recategorize these patients into two subgroups: a subacute to chronic process associated with osteoarthritis and an acute process associated with insufficiency fractures. We retrospectively examined the knee MRIs of 39 patients with non-specific interpretations of osteochondral abnormalities. There were a total of 52 subchondral lesions without any known traumatic event and no prior surgery. All lesions evaluated had MR features previously ascribed to SONK. Several MR characteristics were then assessed: presence or absence of a line, size, zonal location, T1 and T2 signal, associated marrow edema, associated ipsilateral meniscal tear, and associated ipsilateral cartilage defects. The abnormalities with linear components (insufficiency fractures) tended to be larger (P<0.01) and were associated with a severe amount of marrow edema (P<0.0001) consistent with an acute process. The non-linear abnormalities were more associated with cartilage defects (P=0.01) and less marrow edema consistent with osteoarthritis and a subacute to chronic process. This association of SONK-like abnormalities with osteoarthritis and insufficiency fractures casts doubt on the validity of the term ''spontaneous osteonecrosis'' as it is currently applied, and further investigation into the separate etiologies of these subchondral marrow lesions is needed.

Cytogenetic abnormalities, including karyotype aberrations, gene mutations and gene expression abnormalities are the most important diagnostic tools in diagnosis, classification and prognosis in acute myeloid leukemias. Based on World Health Organization (WHO classification, acute myeloid leukemias can be divided to four groups.

Recently, the role of microRNAs (miRNAs in both normal hematopoiesis and myeloid leukemic cell differentiation in myeloid lineage has been specified. miRNAs can be used instead of genes for AML diagnosis and classification in the future, and can also play a decisive role in the evaluation of relapse as well as response to treatment in the patients. Therefore, their use in clinical trials can affect treatment protocols and play a role in therapeutic strategies for these patients. In this review, we have examined rare cytogenetic abnormalities in different groups of acute myeloid leukemias according to WHO classification, and the role of miRNA expression in classification, diagnosis and response to treatment of these disorders has also been dealt with.

    2013-10-01

    Acute leukaemia of ambiguous lineage (ALAL) is a rare complex entity with heterogeneous clinical, immunophenotypic, cytogenetic and molecular genetic features and adverse outcome. According to World Health Organization 2008 classification, ALAL encompasses those leukaemias that show no clear evidence of differentiation along a single lineage. The rarity of ALAL and the lack of uniform diagnostic criteria have made it difficult to establish its cytogenetic features, although cytogenetic analysis reveals clonal chromosomal abnormalities in 59-91% of patients. This article focuses on the significance of cytogenetic analysis in ALAL supporting the importance of cytogenetic analysis in the pathogenesis, diagnosis, prognosis, follow up and treatment selection of ALAL. It reviews in detail the types of chromosomal aberrations, their molecular background, their correlation with immunophenotype and age distribution and their prognostic relevance. It also summarizes some novel chromosome aberrations that have been observed only once. Furthermore, it highlights the ongoing and future research on ALAL in the field of cytogenetics. © 2013 John Wiley & Sons Ltd.

    Quantitation of D-dimer level during a sickling crisis and its correlation with other clinical abnormalities. Prospective longitudinal study. Armed Forces Hospital, Southern Region, Kingdom of Saudi Arabia. Adult patients (12 years and older) admitted acutely with a sickle cell crisis who consent to taking part in the study. Candidates may re-participate if they are readmitted with a further acute painful crisis. 36 patients with homozygous sickle cell disease consented to take part in the study. D-dimer levels were raised in 31 (68.9%) of 45 episodes of painful crisis of whom 13 had an abnormal chest X-ray. Of those with a normal chest X-ray only one patient had a raised D-dimer level: sensitivity of 92.3%, specificity 40.6%, positive predictive value 38.7% and negative predictive value of 92.9% for an abnormal chest X-ray. D-dimer levels are frequently raised during an acute painful crisis. A normal level has a high negative predictive value for an abnormal chest X-ray.

    Ataxia is a movement disorder that may manifest an acute, intermittent, non progressive or chronic progressive course. Ataxia alone is rare as a para neoplastic sign, especially if it is due to neuroblastoma (abdominal or chest). We report an abdominal neuroblastoma in a two-year-old girl presenting with only acute ataxia and abnormal neuroimaging. Brain MRI showed abnormal signal finding in the medulla, pons, cortico spinal tract and the periventricular space. In the abdominal CT, a mass was detected in the right adrenal gland with calcification and the histopathologic examination re-vealed neuroblastoma. We suggest in children with acute ataxia, with or without opalescence-myoclonus, neuroblastoma should be considered.

    To explore hemorrhage risk and the clinical significance of abnormal change of prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (FIB), plasma thrombin time (TT) and d-dimer (D-D) in de novo acute leukemia (except for APL), the different bleeding manifestations of 114 cases of de novo acute leukemia with different coagulation indexes were analyzed retrospectively. The correlation between these blood coagulation indexes and the possible correlative clinical characteristics were analysed, including age, sex, type of acute leukemia, initial white blood cell(WBC) and platelet(Plt) count, the proportion of blast cells in bone marrow and cytogenetic abnormality of patients at diagnosis. The results indicated that the incidence of abnormal blood coagulation was as high as 78.1% for de novo AL patients. These patients with 5 normal blood coagulation indexes may have mild bleeding manifestation, but the more abnormal indexes, the more severe bleeding. Both PT and D-D were sensitive indexes for diagnosis of level II bleeding. Incidence of abnormal blood coagulation significantly correlates with the proportion of blast cells in bone marrow (χ(2) = 4.184, OR = 1.021, P coagulation. It is concluded that the coagulation and fibrinolysis are abnormal in most patients with de novo acute leukemia. More abnormal indexes indicate more severe bleeding, and both PT and D-D are sensitive indexes for diagnosis of level II bleeding. Higher proportion of blast cells in bone marrow predicts higher incidence of abnormal blood clotting. Acute leukemia with elderly age, high white blood cell count and adverse cytogenetics do not predict severer abnormal blood clotting. Detection of PT, APTT, TT, FIB, and D-D may help to judge whether the patients are in a state of hypercoagulability or disseminated intravenous coagulation, which will provide experiment evidences for early intervention and medication.

    Episodes of acute abnormal uterine bleeding related to uterine fibroids can cause significant morbidity. Traditional management with high-dose hormonal regimens may not be as effective when used in women with fibroids. A 32-year-old woman with a 12 cm uterine fibroid presented with an episode of acute abnormal uterine bleeding requiring blood transfusion. In lieu of using a hormonal maintenance regimen after the bleeding had stabilized, the patient was treated with ulipristal acetate 5 mg daily for three months. Amenorrhea was induced rapidly and the patient had no further episodes of acute excessive uterine bleeding. She subsequently underwent a laparoscopic myomectomy with a satisfactory outcome. Ulipristal acetate has been shown to induce amenorrhea rapidly in women with uterine fibroids, and it can be a useful treatment in the emergency management of fibroid-related acute abnormal uterine bleeding.

    Background and purpose: The fraction of hypoxic cells has been shown to differ substantially among human tumors of the same histological type. In this study, a window chamber model was used to identify possible mechanisms leading to the development of highly different hypoxic fractions in A-07 and R-18 human melanoma xenografts. Materials and methods: Chronic and acute hypoxia was assessed in intradermal tumors using an immunohistochemical and a radiobiological assay. Functional and morphological parameters of the vascular networks of tumors growing in dorsal window chambers were assessed with intravital microscopy. Results: R-18 tumors showed significantly higher hypoxic fractions than A-07 tumors, and the difference was mostly due to acute hypoxia. Compared to A-07 tumors, R-18 tumors showed low vascular densities, low vessel diameters, long vessel segments, low blood flow velocities, frequent fluctuations in blood flow, and a high fraction of narrow vessels with absent or very low and varying flux of red blood cells. Conclusion: The high fraction of acute hypoxia in R-18 tumors was a consequence of frequent fluctuations in blood flow and red blood cell flux combined with low vascular density. The fluctuations were most likely caused by high geometric resistance to blood flow in the tumor microvasculature.

    Acute pyelonephritis (APN) in childhood can lead to renal scarring (RS), which carries a risk of subsequent hypertension and renal failure. Every effort must be done in order to identify high risk children who need a more close follow-up. Renal scintigraphy is the procedure of choice for diagnosis and follow-up of children with APN. The aim of this prospective study was to correlate the acute renal scintigraphic abnormalities with the developing of RS in children with APN. We prospectively analyzed 47 patients (94 renal units (RU)), 24 girls, with a first episode of APN diagnosed with renal scintigraphy performed during the first months of the beginning of the symptoms. All children with urinary tract malformations were excluded. The mean age of the group was 1.35 yrs. Follow up scan was performed at least six months after the acute episode. Abnormal findings are presented. During follow up, scar was considered when there was an improvement or no changed of acute abnormalities. Among the 94 RU, 54 had APN. In the follow-up scan there was a normalization of renal parenchymal abnormalities in 33/54 (61 %) and in 21/54 (39%) there was an improvement or no changes (scar). The relation between acute scintigraphic abnormalities and renal scars are presented. The evolution of scintigraphic abnormalities in children with APN is also presented. According to our results, RS developed significant more in kidneys with decreased size (p=0.05), diffuse parenchymal abnormalities (p=0.02) and relative renal function less than 45% (p=0.008), specially if it was less or equal to 35% (p=0.00008). Therefore, we can predict a worst evolution in kidneys with these anomalies during APN

    Objective: To describe acute EEG findings in HIV-infected adults with new-onset seizure, assess baseline clinical characteristics associated with EEG abnormalities, and evaluate the relationship between EEG abnormalities and recurrent seizure. Methods: Eighty-one HIV-infected adults with new-onset seizure had EEG recordings during their index admission. Baseline characteristics assessed included HIV stage, seizure semiology, serum and CSF studies, neuroimaging, cognitive function based on the Zambian Mini-Mental State Examination and International HIV Dementia Scale, and psychiatric symptoms using the Shona Symptom Questionnaire. We evaluated the relationship between baseline characteristics and EEG abnormalities. Patients were followed for seizure recurrence, and the association between acute EEG abnormalities and seizure recurrence was assessed. Death was a secondary outcome. Results: Fifty-five patients had abnormal EEGs (68%): 18 (22%) had interictal spikes (12) or a recorded seizure (6). Among baseline clinical characteristics, more advanced HIV disease (p = 0.039) and any imaging abnormality (p = 0.027) were associated with abnormal EEGs. Cortical (p = 0.008) and white matter (p = 0.004) abnormalities were associated with slow posterior dominant rhythm. Patients were followed for a median of 303 days (interquartile range 103–560). Twenty-four (30%) died and 23 (28%) had recurrent seizures. EEG abnormalities were not associated with recurrent seizure. There was a nonsignificant association between seizures recorded during EEG and death (67% vs 26%, p = 0.051). Conclusions: EEG abnormalities are common in this population, particularly in patients with imaging abnormalities and advanced HIV. Acute EEG abnormalities were not associated with recurrent seizure, but high mortality rates during follow-up limited this analysis. PMID:25740861

    Full Text Available Acute flaccid paralysis (AFP is a complex clinical syndrome with a broad array of potential etiologies that vary with age. We present our experience of acute onset lower motor neuron paralysis. Materials and Methods: One hundred and thirty-three consecutive adult patients presenting with weakness of duration less than four weeks over 12 months period were enrolled. Detailed history, clinical examination, and relevant investigations according to a pre-defined diagnostic algorithm were carried out. The patients were followed through their hospital stay till discharge or death. Results: The mean age was 33.27 (range 13-89 years with male preponderance (67.7%. The most common etiology was neuroparalytic snake envenomation (51.9%, followed by Guillain Barre syndrome (33.1%, constituting 85% of all patients. Hypokalemic paralysis (7.5% and acute intermittent porphyria (4.5% were the other important conditions. We did not encounter any case of acute polio mylitis in adults. In-hospital mortality due to respiratory paralysis was 9%. Conclusion: Neuroparalytic snakebite and Guillain Barre syndrome were the most common causes of acute flaccid paralysis in adults in our study.

    Movement abnormalities are frequently reported in children with 22q11.2 deletion syndrome (22q11.2DS), but knowledge in this area is scarce in the increasing adult population. We report on five individuals illustrative of movement disorders and other motor abnormalities in adults with 22q11.2DS. In addition to an increased susceptibility to neuropsychiatric disorders, seizures, and early-onset Parkinson disease, the underlying brain dysfunction associated with 22q11.2DS may give rise to an increased vulnerability to multiple movement abnormalities, including those influenced by medications. Movement abnormalities may also be secondary to treatable endocrine diseases and congenital musculoskeletal abnormalities. We propose that movement abnormalities may be common in adults with 22q11.2DS and discuss the implications and challenges important to clinical practice. PMID:25684639

    The effect of monosomal karyotype (MK), complex karyotype (CK), and chromosome 17 abnormalities (abnl 17) on prognosis in B-cell acute lymphoid leukemia (B-ALL) has not yet been established. We conducted a retrospective analysis of prognostic factors on 237 adult patients with B-ALL treated at our institution. Older age (older than 60 years), higher white blood cell count (> 30), and abnl 17 were associated with shorter overall survival in univariate analysis, but multivariable analysis only identified older age as an independent poor prognostic actor. There was a significant correlation between abnl 17 and older age. In contrast to the patients with acute myeloid leukemia, our results show that MK and CK do not play a predictive role in patients with B-ALL, but further study is required to determine whether specific changes on chromosome 17 might have prognostic value when investigated separately.

    Full Text Available Objectives: Electrocardiographic (ECG changes are reported frequently after acute strokes. It seems that cardiovascular effects of strokes are modulated by concomitant or pre-existent cardiac diseases, and are also related to the type of cerebrovascular disease and its localization. We aimed to determine the pattern of ECG changes associated with pathophysiologic categories of acute stroke among patients with/without cardiovascular disease and to determine if specific ECG changes are related to the location of the lesion. Materials and Methods : The electrocardiographic records of 361 patients with acute stroke were studied to assess the relative frequencies of ECG abnormalities among the pathophysiologic categories of stroke. Results: In the present study, the most common ECG abnormalities associated with stroke were T-wave abnormalities, prolonged QTc interval and arrhythmias, which were respectively found in 39.9%, 32.4%, and 27.1% of the stroke patients and 28.9%, 30.7%, and 16.2 of the patients with no primary cardiac disease. We observed that other ECG changes comprising pathologic Q- wave, ST-segment depression, ST-segment elevation, and prominent U wave may also occur in selected or non-selected stroke patients; thereby simulate an acute myocardial injury. We observed an increased number of patients with abnormal T-wave and posterior fossa bleedings and more rhythm disturbances for ischemic lesions, localized in the anterior fossa. Conclusion: Ischemia-like ECG changes and arrhythmias are frequently seen in stroke patients, even in those with no history or signs of primary heart disease, which support a central nervous system origin of these ECG abnormalities. Further study is necessary to better define the brain-heart interaction.

    2004-10-01

    Objective: To determine the prevalence and morphologic helical computed tomography (CT) features of peripancreatic vascular abnormalities in patients with acute pancreatic inflammatory disease in correlation with the severity of the pancreatitis. Materials and methods: One hundred and fifty-nine contrast-enhanced helical CT scans of 100 consecutive patients with acute pancreatitis were retrospectively and independently reviewed by three observers. CT scans were scored using the CT severity index (CTSI): pancreatitis was graded as mild (0-2 points), moderate (3-6 points), and severe (7-10 points). Interobserver agreement for both the CT severity index and the presence of peripancreatic vascular abnormalities was calculated (K-statistic). Correlation between the prevalence of complications and the degree of pancreatitis was estimated using Fisher's exact test. Results: The severity of pancreatitis was graded as mild (n=59 scans), moderate (n=82 scans), and severe (n=18 scans). Venous abnormalities detected included splenic vein (SV) thrombosis (31 scans, 19 patients), superior mesenteric vein (SMV) thrombosis (20 scans, 14 patients), and portal vein (PV) thrombosis (17 scans, 13 patients). Arterial hemorrhage occurred in five patients (6 scans). In our series, no cases of arterial pseudoaneurysm formation were detected. The interobserver agreement range for scoring the degree of pancreatitis and the overall presence of major vascular abnormalities was 75.5-79.2 and 86.2-98.8%, respectively. The presence of the vascular abnormalities in correlation with the severity of pancreatitis was variable. Conclusion: Vascular abnormalities are relatively common CT findings in association with acute pancreatitis. The CT severity index is insufficiently accurate in predicting some of these complications since no statistically significant correlation between their prevalence and the severity of pancreatitis could be established.

    2016-12-17

    Over the past several decades, the incidence of bacterial meningitis in children has decreased but there remains a significant burden of disease in adults, with a mortality of up to 30%. Although the pathogenesis of bacterial meningitis is not completely understood, knowledge of bacterial invasion and entry into the CNS is improving. Clinical features alone cannot determine whether meningitis is present and analysis of cerebrospinal fluid is essential for diagnosis. Newer technologies, such as multiplex PCR, and novel diagnostic platforms that incorporate proteomics and genetic sequencing, might help provide a quicker and more accurate diagnosis. Even with appropriate antimicrobial therapy, mortality is high and so attention has focused on adjunctive therapies; adjunctive corticosteroids are beneficial in certain circumstances. Any further improvements in outcome are likely to come from either modulation of the host response or novel approaches to therapy, rather than new antibiotics. Ultimately, the best hope to reduce the disease burden is with broadly protective vaccines. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2017-06-01

    Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy. Relapse of ALL occurs in 15%-20% of patients, with 2%-6% occurring exclusively in extramedullary sites. Relapse of ALL in gynecologic organs is extremely rare. We present a case of a 12-year-old girl with a history of ALL who was referred to the pediatric gynecology clinic with abnormal uterine bleeding. She was determined to have an extramedullary uterine relapse of her ALL. Abnormal uterine bleeding in the setting of childhood malignancy is a frequent reason for consultation to pediatric and adolescent gynecology services. This bleeding is commonly attributed to thrombocytopenia due to bone marrow suppressive chemotherapeutic agents. However, as shown in this report, abnormal uterine bleeding might be a manifestation of an extramedullary relapse. Copyright © 2017 North American Society for Pediatric and Adolescent Gynecology.

    The aim of this study is to investigate the relationship between abnormal retropharyngeal lymph nodes (RPLNs) and sinonasal malignancies among adults. Magnetic resonance and computed tomography images from 89 patients over 20 years old who were all histopathologically confirmed to have sinonasal malignancies from September 2001 to April 2014 were assessed retrospectively. Abnormal RPLNs were determined as those >5 mm in shortest axis or showing heterogeneous enhancement on axial images. Locations of sinonasal malignancies were categorized using the anterior border of the pterygopalatine fossa as a boundary: (a) anterior lesions, only present anterior to the boundary, or (b) posterior lesions, present or extending posterior to the boundary. Fisher's exact test was used for the analysis of the relationship between frequency of abnormal RPLNs and lesion location. Abnormal RPLNs were present in 13 of 89 patients (15 %), including 6 of 41 squamous cell carcinomas (15 %), 4 of 24 malignant lymphomas (17 %), 3 of 5 olfactory neuroblastomas (60 %), and 0 of 19 others (0 %). Four of the 39 patients (10 %) with anterior lesions showed abnormal RPLNs, compared to 9 of 50 patients (18 %) with posterior lesions. No significant difference in frequency of abnormal RPLNs was apparent between anterior and posterior lesions (P = 0.37). In primary sinonasal malignancies among adults, the highest incidence of abnormal RPLNs was seen with olfactory neuroblastoma. The frequency of abnormal RPLNs was unaffected by the location of sinonasal malignancies among adults. (orig.)

    Full Text Available Introduction: Cancer of the cervix is the second most common cancer among women worldwide and the frequency of precancerous lesions is increasing among adolescents. Objective: To study and compare the frequency of epithelial abnormalities in cervical cytology exams in adolescents and adults. Materials and methods: Retrospective study based on analysis of reports of cytology exams performed in the years 2000 and 2010 in adolescents (12-18 years old and in adult women. The frequency of cytological alterations was explored, stratifying them into high-grade/carcinoma and low-grade lesions. Results: In 2000, rates of epithelial abnormalities were 3.08% in adolescents and 1.39% in adult females, and were 4.76% and 1.83% in 2010, respectively. The high-grade lesions/carcinomas were more common among adults in both years. Discussion: There was an increase in prevalence of epithelial abnormalities in the last decade, both in adolescents and in adults. Proportionally, the increase was higher among adolescents (6.7% than in adults (2.2%. However, the rate of high-grade lesions/carcinoma was higher among adult women in the two analyzed years. Conclusion: It was observed that the frequency of cervical epithelial abnormalities was higher among adolescents than adults and increased between 2000 and 2010.

    Acute uncomplicated UTI is one of the most common problems for which young women seek medical attention, and it accounts for considerable morbidity and health care costs. Acute cystitis is a superficial infection of the bladder mucosa, whereas pyelonephritis involves tissue invasion of the upper urinary tract. Localization tests suggest that as many as one third of episodes of acute cystitis are associated with silent upper tract involvement. Acute cystitis or pyelonephritis in the adult patient should be considered uncomplicated if the patient is not pregnant or elderly, if there has been no recent instrumentation or antimicrobial treatment, and if there are no known functional or anatomic abnormalities of the genitourinary tract. Most of these infections are caused by E. coli, which are susceptible to many oral antimicrobials. Because of the superficial nature of cystitis, single-dose and 3-day regimens have gained wide acceptance as the preferred methods of treatment. Review of the published data suggests that a 3-day regimen is more effective than a single-dose regimen for all antimicrobials tested. Regimens with trimethoprim-sulfamethoxazole appear to be more effective than those with beta-lactams, regardless of the duration. Acute pyelonephritis does not necessarily imply a complicated infection. Upper tract infection with highly virulent uropathogens in an otherwise healthy woman may be considered an uncomplicated infection. The optimal treatment duration for acute uncomplicated pyelonephritis has not been established, and 14-day regimens are often used. We prefer to use antimicrobials that attain high renal tissue levels, such as trimethoprim-sulfamethoxazole or quinolones, for pyelonephritis. Women with frequently recurring infections can be successfully managed by continuous prophylaxis, either daily or thrice-weekly, by postcoital prophylaxis, or, in compliant patients, by early self-administration of single-dose or 3-day therapy as soon as typical

    To determine the rate of abnormal eating behaviours in obese adult patients with attention deficit hyperactivity disorder (ADHD) in comparison with obese adult patients without ADHD. This case-control study includes: obese adult patients defined by a body mass index (BMI) ≥30 kg/m², screening positive in the adult ADHD self-report scale-V1.1. (ASRS-V1.1), attending the Nutrition Section, as cases; and obese adult patients screening negative, as controls. Weight, height and BMI were determined in all the participants. The rate of abnormal eating behaviours was determined using an eating pattern questionnaire. Forty-five out of 51 (88.2%) cases vs 127 out of 179 (70.9%) controls had abnormal eating behaviours (p=0.01). Eating between-meal snacks was found in 39 (76.5%) cases vs 107 (59.8%) controls (p=0.03), going on binge eating episodes in 28 (54.9%) vs 42 (23.5%) (p=0.00), waking up at night to eat in 11 (21.6%) vs 16 (8.9%) (p=0.01), eating large amounts of food in 13 (25.5%) vs 38 (21.2%) (p=0.52), and eating in secret in 11 (21.6%) vs 16 (8.9%) (p=0.01), respectively. This is the first study that determines the rate of these abnormal eating behaviours in obese adult patients with ADHD in comparison with obese adult patients without ADHD. A high rate of abnormal eating behaviours was observed in obese patients with ADHD. Our results suggest that ADHD is a risk factor for the development of these abnormal eating behaviours, which may be contributing factors of obesity and the unsuccessful treatment of obese patients.

    Full Text Available Studies have shown that low forced vital capacity (LFVC is associated with atherosclerosis. However, it is unclear whether LFVC is associated with resting electrocardiographic ST-T abnormalities, a common finding that is prognostic for cardiovascular events. Therefore, pulmonary functions, ST-T abnormalities defined with Minnesota Code, and cardiometabolic risk factors were examined in a cross-sectional study of 1,653 asymptomatic adults without past history of coronary heart diseases.

    Studies have shown that low forced vital capacity (LFVC) is associated with atherosclerosis. However, it is unclear whether LFVC is associated with resting electrocardiographic ST-T abnormalities, a common finding that is prognostic for cardiovascular events. Therefore, pulmonary functions, ST-T abnormalities defined with Minnesota Code, and cardiometabolic risk factors were examined in a cross-sectional study of 1,653 asymptomatic adults without past history of coronary heart diseases. The prevalence of diabetes, metabolic syndrome, and ST-T abnormalities significantly increased with decreasing percent of predicted forced vital capacity (%PFVC). ST-T abnormalities were observed in 73 subjects (4.4% in total).

Similar trends were observed when subjects were divided into quartiles according to percent of predicted forced expiratory volume in 1 second (FEV1), but not the ratio of FEV1/FVC.

    Transcobalamin II is a serum transport protein for vitamin B12. Small variations in TC-II affinity were recently linked to a high homocysteine level and increased frequency of neural tube defects. Complete absence of TC-II or total functional abnormality causes tissue vitamin B12 deficiency resulting in a severe disease with megaloblastic anemia and immunologic and intestinal abnormalities in the first months of life. This condition was described in hereditary autosomal-recessive form. Low serum TC-II without any symptoms or clinical significance was noted in relatives of affected homozygotes. To study 23 members of a four-generation family with hereditary vitamin B12 deficiency and neurologic disorders. Thorough neurologic, hematologic and family studies were supplemented by transcobalamin studies in 20 family members. Partial TC-II deficiency was found in 19 subjects. Apo TC-II (free TC-II unbound to vitamin B12) and total unsaturated B12 binding capacity were low in all tested individuals but one, and holo TC-II (TC-II bound by vitamin B12) was low in all family members. The presentation of the disease was chronic rather than acute. Early signs in children and young adults were dyslexia, decreased IQ, vertigo, plantar clonus and personality disorders. Interestingly, affected children and young adults had normal or slightly decreased serum vitamin B12 levels but were not anemic. Low serum B12 levels were measured in early adulthood. In mid-late adulthood megaloblastic anemia and subacute combined degeneration of the spinal cord were diagnosed. Treatment with B12 injections resulted in a significant improvement. The pedigree is compatible with an autosomal-dominant transmission. This family study suggests a genetic heterogeneity of TC-II deficiency. We report the first family with a hereditary transmitted condition of low serum TC-II (partial TC-II deficiency) associated with neurologic and mental manifestations in childhood. Partial TC-II deficiency may decrease

    Purpose: The purpose of the study was to evaluate unenhanced Magnetic Resonance Imaging (MRI) for the diagnosis of appendicitis or another surgery-requiring condition in an adult population scheduled for emergency appendectomy based on a clinical diagnosis of suspected acute appendicitis. Materials and methods: The prospective study included 48 consecutive patients (29 female, 19 male, 18-70 years old, mean age = 37.1 years). MRI examination was designed to be comfortable and fast; no contrast was administered. The sequences were performed during quiet respiration. The MRI findings were reviewed by two radiologists and one surgeon independent of each other and compared with surgical and pathological records. Results: According to the surgical and histopathological findings 30 of 48 patients (63%) had acute appendicitis. Of the remaining 18 patients, 4 patients had no reasons for the clinical symptoms and 14 patients had other pathology. For the three reviewers the performance of MRI in the diagnosis of acute appendicitis showed the following sensitivity, specificity and accuracy ranges: 83-93%, 50-83% and 77-83%. Moderate (κ = 0.51) and fair (κ = 0.31) interobserver agreements in the MR diagnosis of acute appendicitis were found between the reviewers. Sensitivity, specificity and accuracy values for overall performance of MRI in detecting pelvic abnormalities were 100%, 75% (3 of 4 healthy patients were identified by MRI) and 98%, respectively. Conclusion: Unenhanced fast MRI is feasible as an additional fast screening before the appendectomy. It may prevent unnecessary surgeries. The fast MRI examination can be adequately performed on an MRI unit of broad range of field strengths.

    Ingestion of paraquat causes multi-organ failure. Prognosis is best estimated through measurement of blood paraquat concentrations but this facility is not available in most hospitals. We studied the prognostic significance of abnormal pancreatic enzymes for survival. Patients with acute paraquat poisoning were recruited. An extensive series of blood tests including serum amylase were serially checked. Patients were sorted according to their serum amylase activity (normal [660 U/L]), and survival compared between groups. 177 patients were enrolled to the study, of whom 67 died and 110 survived. 122 (70.62%), 27 (15.25%) and 25 (14.13%) patients were in the normal, mildly elevated and elevated amylase activity groups, respectively. The case fatality in the elevated group was 100% compared to 17% in the normal group (P paraquat death prediction: amylase, PaCO2, leukocyte number, and neutrophil percentage. Models using pancreatic enzyme activity showed good prediction power. We have found that abnormal pancreatic enzymes are useful prognostic marker of death after acute paraquat poisoning. Including serum amylase activity into a prognostic model provides a good prognostication.

    Full Text Available Deletions on chromosomes 5 and 7 are frequently seen in myelodysplastic syndrome (MDS and acute myeloid leukemia (AML. It is assumed that these deletions indicate loss of tumor suppressor genes on these chromosomes and until these tumor suppressor genes are identified, the functional consequences of these deletions and the molecular basis of these myeloid disorders cannot be completely understood. We evaluated loss of heterozygosity (LOH in 44 patients (18 MDS and 26 AML, diagnosed according to WHO classification criteria at diagnosis, using a four-microsatellite marker panel: an intragenic marker on the 7th intron of gene IRF-1 of the 5q31.1 region and three markers located inside the 7q31.1 region and correlated the LOH with karyotype abnormalities. The microsatellites chosen corresponded to chromosome regions frequently deleted in MDS/AML. The samples with Q (peak area less than or equal to 0.50 were indicative of LOH. The percent of informative samples (i.e., heterozygous for the intragenic microsatellite in gene IRF-1 and in loci D7S486, D7S515 and D7S522 were 66.6, 73.7, 75.5, and 48.8%, respectively. Cytogenetic abnormalities by G-banding were found in 36% (16/44 of the patients (2 of 18 MDS and 14 of 26 AML patients. We found a significantly positive association of the occurrence of LOH with abnormal karyotype (P < 0.05; chi-square test and there were cases with LOH but the karyotype was normal (by G-banding. These data indicate that LOH in different microsatellite markers is possibly an event previous to chromosomal abnormalities in these myeloid neoplasias.

    To determine clinical, clinicopathologic, radiographic, ultrasonographic, and coagulation abnormalities in dogs in which acute pancreatitis was fatal. Retrospective study. 70 dogs. History, clinical signs, and physical examination findings at the time of initial evaluation at the veterinary teaching hospital; results of pretreatment laboratory tests, abdominal radiography, and ultrasonography; and histologic abnormalities were obtained from medical records. Clinical signs included anorexia, vomiting, Weakness, diarrhea, polyuria and polydipsia, neurologic abnormalities, melena, weight loss, hematemesis, and passage of frank blood in feces. At the time of initial examination at the veterinary teaching hospital, 68 (97%) dogs were dehydrated, 18 (26%) were icteric, 22 (32%) were febrile, 40 (58%) had signs of abdominal pain, and 30 (43%) were classified as overweight or obese. Most dogs had leukocytosis, neutrophilia with a left shift, and thrombocytopenia. Various serum biochemical abnormalities were identified, including hypoglycemia, azotemia, hypercalcemia and other electrolyte abnormalities, hypoalbuminemia, high hepatic and pancreatic enzyme activities, hypercholesterolemia, and lipemia. For 17 of 28 (61%) dogs, results of coagulation function tests were abnormal. Results of abdominal ultrasonography and radiography were consistent with a diagnosis of acute pancreatitis in 23 of 34 (68%) and 10 of 41 (24%) dogs, respectively. For 2 dogs, results of abdominal ultrasonography were not suggestive of acute pancreatitis, but results of abdominal radiography were. Clinical signs and results of clinicopathologic tests are inconsistent. Abdominal ultrasonography may be valuable in the diagnostic evaluation of dogs suspected to have acute pancreatitis

    Aplastic anaemia (AA) can precede acute lymphoblastic leukaemia (ALL) in 2% of children but this is rarely reported to occur in adults. A 21-year-old male presented with bone marrow failure and bone marrow biopsy showed a profoundly hypocellular marrow. He recovered spontaneously but represented 2 months later when he was diagnosed with pre-B acute lymphoblastic leukaemia. Chromosomal examination revealed 46,XY,del(9)(q13q34). To the best of our knowledge this is the first case to be reported of aplasia preceding ALL with 9q minus as the sole chromosomal abnormality.

    The correlates of abnormal right ventricular (RV) thallium uptake were examined in 116 patients with documented acute myocardial infarction (AMI) who underwent predischarge thallium-201 scintigraphy at rest, radionuclide angiography and 24-hour ambulatory electrocardiography. The patients were separated into 2 groups: patients group 1 (n = 31) had increased RV thallium uptake and those in group 2 (n = 85) had no such uptake. The 2 groups were comparable in age, type and site of AMI, peak creatine kinase level, systolic blood pressure and heart rate. However, compared with group 2, group 1 had a lower mean left ventricular (LV) ejection fraction (33 +/- 15% vs 39 +/- 14%, p less than 0.05), higher prevalence of increased lung thallium uptake (45% vs 22%, p less than 0.02), more extensive LV perfusion defects (4.4 +/- 2.9 vs 3.0 +/- 3.0 segments, p less than 0.03) and more complex ventricular arrhythmias (55% vs 35%, p less than 0.05). At a mean follow-up of 6 months, 17 patients (8 in group 1 and 9 in group 2) died from cardiac causes. Actuarial life-table analysis showed that the survival rate was better in group 2 than in group 1 (Mantel-Cox statistics = 4.62, p = 0.03). Thus, patients with AMI and abnormal RV thallium uptake have worse LV function, more complex ventricular arrhythmias and worse prognosis

    Full Text Available Acute lymphoblastic leukemia (ALL in adults is a relatively rare malignancy. The typical presentation includes signs and symptoms associated with bone marrow failure, including fevers, infections, fatigue, and excessive bruising. In this article, we report an unusual systemic presentation of ALL in a previously healthy 18-year-old man. He initially presented with several-day history of nausea and vomiting, 10-pound weight loss, and right upper quadrant abdominal pain with evidence of acute hepatocellular liver injury (elevations in aspartate aminotransferase/alanine aminotransferase and elevation in serum creatinine. Further history revealed that he just joined the Marine Corp; in preparation, he had been lifting weights and taking protein and creatine supplements. A complete serological evaluation for liver disease was negative and creatine phosphokinase was normal. His aspartate aminotransferase and alanine aminotransferase declined, and he was discharged with expected improvement. However, he returned one week later with continued symptoms and greater elevation of aminotransferases. Liver biopsy was nondiagnostic, revealing scattered portal and lobular inflammatory cells (primarily lymphocytes felt to be consistent with drug-induced liver injury or viral hepatitis. Given his elevated creatinine, unresponsive to aggressive volume expansion, a kidney biopsy was performed, revealing normal histology. He subsequently developed an extensive left lower extremity deep venous thrombosis. Given his deep venous thrombosis, his peripheral blood was sent for flow cytometry, which revealed lymphoblasts. Bone marrow biopsy revealed 78% blasts with markers consistent with acute B-cell lymphoblastic leukemia. This report emphasizes that right upper quadrant abdominal pain with liver test abnormalities may be the initial presentation of a systemic illness such as ALL.

    The purpose of this study was to assess whether variability exists in the management of acute abnormal uterine bleeding (AUB) in adolescents between pediatric Emergency Department (ED) physicians, pediatric gynecologists, and adolescent medicine specialists. Retrospective chart review. Tertiary care medical center ED. We included girls aged 9-22 years who presented from July 2008 to June 2014 with the complaint of acute AUB. Patients were identified using the International Classification of Diseases, ninth revision codes for heavy menstrual bleeding, AUB, and irregular menses. Exclusion criteria included pregnancy and current use of hormonal therapy. One hundred fifty patients were included. Among those evaluated, 61% (n = 92) were prescribed hormonal medication to stop their bleeding by providers from the ED, Adolescent Medicine, or Pediatric Gynecology. ED physicians prescribed mostly single-dose and multidose taper combined oral contraceptive pills (85%; n = 24), compared with Adolescent Medicine (54%, n = 7), and Gynecology (28%, n = 13). Pediatric gynecologists were more likely than ED physicians to treat patients with norethindrone acetate, either alone or in combination with a single dose combined oral contraceptive pill (61%, n = 33 vs 7%, n = 2; P bleeding, side effects, and patient satisfaction are valuable next steps.

    Annette Fox

    Full Text Available The pathogenesis of acute measles encephalitis (AME is poorly understood. Treatment with immune-modulators is based on theories that post-infectious autoimmune responses cause demyelination. The clinical course and immunological parameters of AME were examined during an outbreak in Vietnam.Fifteen measles IgM-positive patients with confusion or Glasgow Coma Scale (GCS score below 13, and thirteen with uncomplicated measles were enrolled from 2008-2010. Standardized clinical exams were performed and blood collected for lymphocyte and measles- and auto-antibody analysis. The median age of AME patients was 21 years, similar to controls. Eleven reported receiving measles vaccination when aged one year. Confusion developed a median of 4 days after rash. Six patients had GCS <8 and four required mechanical ventilation. CSF showed pleocytosis (64% and proteinorrhachia (71% but measles virus RNA was not detected. MRI revealed bilateral lesions in the cerebellum and brain stem in some patients. Most received dexamethasone +/- IVIG within 4 days of admission but symptoms persisted for ≥3 weeks in five. The concentration of voltage gated calcium channel-complex-reactive antibodies was 900 pM in one patient, and declined to 609 pM ∼ 3 months later. Measles-reactive IgG antibody avidity was high in AME patients born after vaccine coverage exceeded 50% (∼ 25 years earlier. AME patients had low CD4 (218/µl, p = 0.029 and CD8 (200/µl, p = 0.012 T-cell counts compared to controls.Young adults presenting with AME in Vietnam reported a history of one prior measles immunization, and those aged <25 years had high measles-reactive IgG avidity indicative of prior vaccination. This suggests that one-dose measles immunization is not sufficient to prevent AME in young adults and reinforces the importance of maintaining high coverage with a two-dose measles immunization schedule. Treatment with corticosteroids and IVIG is common practice, and should be

    Mild traumatic brain injury (MTBI) is a common reason for hospital attendance and is associated with significant delayed morbidity. We studied a series of 80 persons with MTBI. Magnetic resonance imaging (MRI) and neuropsychological testing were used in the acute phase and a questionnaire for post-concussion syndrome (PCS) and return to work status at 6 months. In 26 subjects abnormalities were seen on MRI, of which 5 were definitely traumatic. There was weak correlation with abnormal neuropsychological tests for attention in the acute period. There was no significant correlation with a questionnaire for PCS and return to work status. Although non-specific abnormalities are frequently seen, standard MRI techniques are not helpful in identifying patients with MTBI who are likely to have delayed recovery. (orig.)

    Studying the neural correlates of smoking behaviors in young adulthood is of great importance to improve treatment outcomes. In previous addiction studies, the important roles of the salience network (SN) in drug cue processing and cognitive control have been revealed. Unfortunately, few studies focused on the resting-state functional connectivity and structural integrity abnormalities of SN in young adult smokers, and less is known about its association with smoking behaviors and cognitive control deficits. Thirty-one young male adult smokers and 30 age-, education- and gender-matched nonsmokers participated in this study. The structural and functional connectivity differences of SN were investigated between young adult smokers and nonsmokers by using diffusion tensor imaging (DTI) and resting-state functional connectivity (RSFC), which were then correlated with the smoking behavioral assessments (pack-years and Fagerström Test for Nicotine Dependence (FTND)) as well as impaired cognitive control measured by the Stroop task. Within SN, reduced RSFC and increased fractional anisotropy (FA) were found between the anterior cingulate cortex (ACC) and the right insula in young adult smokers relative to nonsmokers. The RSFC between the ACC and right insula was negatively correlated with the number of errors during the incongruent condition of the Stroop task in young adult smokers. Additionally, the right insula-ACC RSFC was negatively correlated with pack-years in young adult smokers. Our results revealed abnormal RSFC and structural integrity within the SN in young adult smokers, which shed new insights into the neural mechanism of nicotine dependence.

    To longitudinally and cross-sectionally evaluate knee abnormalities by sex and age in adolescent and adult volleyball athletes over 2 years using magnetic resonance imaging (MRI). Thirty-six high-level volleyball athletes (18 adolescents: 56% female, mean age 16.0 ± 0.8 years; and 18 adults: 50% female, mean age 46.8 ± 5.1 years) were imaged by MRI at BL and at 2-year follow-up (FU). Prevalence and severity of cartilage lesions, subarticular bone marrow lesions (BMLs), subarticular cysts, osteophytes, and ligament and meniscus integrity were evaluated by sex and by age cohort (adolescents and adults) using the whole-organ MRI score (WORMS). There were no significant longitudinal changes in any of the features within any of the sex or age groups. No significant differences were found in overall prevalence or severity of any of the features between males and females, although at FU, males had a significantly higher prevalence of osteophytes in the medial femorotibial joint (MFTJ) than females (p=0.044). Compared to adolescents, adult volleyball players had a significantly greater prevalence and severity of cartilage lesions (pvolleyball players, but no overall differences by sex. These findings lay the groundwork for further investigations with larger cohorts and longer FU times to determine whether or not these knee abnormalities are associated with the development of OA.

  5. Acute pulmonary parenchymal densities in the adult

    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

    Antisocial personality disorder (ASPD) and psychopathy involve significant interpersonal and behavioural impairments. However, little is known about their underlying neurobiology and in particular, abnormalities in white matter (WM) microstructure. A preliminary diffusion tensor magnetic resonance imaging (DT-MRI) study of adult psychopaths employing tractography revealed abnormalities in the right uncinate fasciculus (UF) (Craig et al., 2009), indicating fronto-limbic disconnectivity. However, it is not clear whether WM abnormalities are restricted to this tract or are or more widespread, including other tracts which are involved in connectivity with the frontal lobe. We performed whole brain voxel-based analyses on WM fractional anisotropy (FA) and mean diffusivity (MD) maps acquired with DT-MRI to compare 15 adults with ASPD and healthy age, handedness and IQ-matched controls. Also, within ASPD subjects we related differences in FA and MD to measures of psychopathy. Significant WM FA reduction and MD increases were found respectively in ASPD subjects relative to controls. FA was bilaterally reduced in the genu of corpus callosum while in the right frontal lobe FA reduction was found in the UF, inferior fronto-occipital fasciculus (IFOF), anterior corona radiata and anterior limb and genu of the internal capsule. These differences negatively correlated with measures of psychopathy. Also in the right frontal lobe, increased MD was found in the IFOF and UF, and the corpus callosum and anterior corona radiata. There was a significant positive correlation between MD and psychopathy scores. The present study confirms a previous report of reduced FA in the UF. Additionally, we report for the first time, FA deficits in tracts involved in interhemispheric as well as frontal lobe connectivity in conjunction with MD increases in the frontal lobe. Hence, we provide evidence of significant WM microstructural abnormalities in frontal brain regions in ASPD and psychopathy

  7. Abnormal brain connectivity patterns in adults with ADHD: a coherence study.

    Full Text Available Studies based on functional magnetic resonance imaging (fMRI during the resting state have shown decreased functional connectivity between the dorsal anterior cingulate cortex (dACC and regions of the Default Mode Network (DMN in adult patients with Attention-Deficit/Hyperactivity Disorder (ADHD relative to subjects with typical development (TD. Most studies used Pearson correlation coefficients among the BOLD signals from different brain regions to quantify functional connectivity. Since the Pearson correlation analysis only provides a limited description of functional connectivity, we investigated functional connectivity between the dACC and the posterior cingulate cortex (PCC in three groups (adult patients with ADHD, n=21; TD age-matched subjects, n=21; young TD subjects, n=21 using a more comprehensive analytical approach - unsupervised machine learning using a one-class support vector machine (OC-SVM that quantifies an abnormality index for each individual. The median abnormality index for patients with ADHD was greater than for TD age-matched subjects (p=0.014; the ADHD and young TD indices did not differ significantly (p=0.480; the median abnormality index of young TD was greater than that of TD age-matched subjects (p=0.016. Low frequencies below 0.05 Hz and around 0.20 Hz were the most relevant for discriminating between ADHD patients and TD age-matched controls and between the older and younger TD subjects. In addition, we validated our approach using the fMRI data of children publicly released by the ADHD-200 Competition, obtaining similar results. Our findings suggest that the abnormal coherence patterns observed in patients with ADHD in this study resemble the patterns observed in young typically developing subjects, which reinforces the hypothesis that ADHD is associated with brain maturation deficits.

    Recent studies indicate that the risk of thrombosis in hematologic patients may be similar or even higher than that found in patients with solid tumors. However, available information about pathogenesis and incidence of thrombosis in acute leukemia is limited. This review focuses on mechanisms underlying thrombosis in acute leukemia and discusses recent literature data. In the last few years, proofs have been provided that leukemic cells release free prothrombotic products, such as micro-vesicles, tissue factors, circulating free DNA and RNA. Furthermore, leukemic blasts can activate the procoagulant population of platelets, which initiate and amplify coagulation, causing thrombosis. In addition to factors produced by acute leukemia itself, others concur to trigger thrombosis. Some drugs, infections and insertion of central venous catheter have been described to increase risk of thrombosis in patients with acute leukemia. Thrombosis represents a serious complication in patients affected by myeloid and lymphoid acute leukemia. A proper knowledge of its pathophysiology and of the predisposing risk factors may allow to implement strategies of prevention. Improving prevention of thrombosis appears a major goal in patients whose frequent conditions of thrombocytopenia impede an adequate delivery of anticoagulant therapy.

    Full Text Available Abstract Background Congenital spinal abnormalities can easily be misdiagnosed on plain radiographs. Additional imaging is warranted in doubtful cases, especially in a setting of acute trauma. Case Presentation This patient presented at the emergency unit of our university hospital after a motor vehicle accident and was sent to our radiology department for imaging of the cervical spine. Initial clinical examination and plain radiographs of the cervical spine were performed but not conclusive. Additional CT of the neck helped establish the right diagnosis. Conclusion CT as a three-dimensional imaging modality with the possibility of multiplanar reconstructions allows for the exact diagnosis and exclusion of acute traumatic lesions of the cervical spine, especially in cases of doubtful plain radiographs and when congenital spinal abnormalities like absent cervical spine pedicle with associated spina bifida may insinuate severe trauma.

    Acute intermittent porphyria (AIP) is an autosomal dominant disorder characterized by insufficient porphobilinogen deaminase (PBGD) activity. When hepatic heme synthesis is induced, porphobilinogen (PBG) and 5-aminolevulinic acid (ALA) accumulate, which causes clinical symptoms such as abdominal pain, neuropathy, and psychiatric disturbances. Our aim was to investigate if hepatocyte transplantation can prevent or minimize the metabolic alterations in an AIP mouse model. We transplanted wild-type hepatocytes into PBGD-deficient mice and induced heme synthesis with phenobarbital. ALA and PBG concentrations in plasma were monitored, and the gene transcriptions of hepatic enzymes ALAS1, PBGD, and CYP2A5 were analyzed. Results were compared with controls and correlated to the percentage of engrafted hepatocytes. The accumulation of ALA and PBG was reduced by approximately 50% after the second hepatocyte transplantation. We detected no difference in mRNA levels of PBGD, ALAS1, or CYP2A5. Engraftment corresponding to 2.7% of the total hepatocyte mass was achieved following two hepatocyte transplantations. A lack of precursor production in less than 3% of the hepatocytes resulted in a 50% reduction in plasma precursor concentrations. This disproportional finding suggests that ALA and PBG produced in PBGD-deficient hepatocytes crossed cellular membranes and was metabolized by transplanted cells. The lack of effect on enzyme mRNA levels suggests that no significant efflux of heme from normal to PBGD-deficient hepatocytes takes place. Further studies are needed to establish the minimal number of engrafted hepatocytes needed to completely correct the metabolic abnormality in AIP and whether amelioration of the metabolic defect by partial restoration of PBGD enzyme activity translates into a clinical effect in human AIP.

    Full Text Available Twenty cases of isolated optic neuritis (15 female, 5 male were studied and followed for several months to years after the initial attack. The mean age of patients was 23 years (range: 15-29 years. The most frequent clinical manifestations were decreased visual acuity and blurred vision. A complete neurological examination was performed. In 15 cases (75% the initial brain MRI was abnormal. In fourteen cases, other signs of multiple sclerosis presented in one month to eight years following the initial attack of optic neuritis; eleven of the latter cases had an abnormal initial MRI. Acute optic neuritis can be considered a presenting feature of multiple sclerosis, particulary in the presence of an abnormal brain MRI.

    Young adults with acute lymphoblastic leukemia are a distinctive category of patients, with substantial difference in disease biology and response to therapy; hence, they pose unique challenges and issues beyond those faced by children and older adults. Despite inferior survival compared to children, there is growing evidence to suggest that young adults have improved outcomes when treated with pediatric-based approaches. With better supportive care and toxicity management and multidisciplinary team and approach, we have made great improvement in outcomes of young adults with ALL. However, despite significant progress, patients with persistence of minimal residual disease have a poor prognosis. This review discusses current controversies in the management of young adults with ALL, outcomes following pediatric and adult protocols, and the role of allogeneic stem cell transplantation. We also explore recent advances in disease monitoring and highlight our approach to incorporation of novel therapies in the management of young adults with ALL.

    The objective of this investigation was to study short-term efficacy and feasibility of a new progestogen-only treatment for outpatient management of acute abnormal uterine bleeding. This was a prospective, single-arm, pilot clinical trial of a progestogen-only bridging treatment for acute abnormal uterine bleeding in nonpregnant, premenopausal women in the Gynecologic Urgent Care Clinic at Harbor-UCLA Medical Center. Subjects were administered a depo-medroxyprogesterone acetate 150 mg intramuscular injection and given medroxyprogesterone acetate 20 mg to be taken orally every 8 hours for 3 days. The primary outcome measures included a percentage of women who stopped bleeding in 5 days, time to bleeding cessation, reduction in numbers of pads used, side effects, and patient satisfaction. All 48 women stopped bleeding within 5 days; 4 women had spotting only at the time of their last contact during the 5 day follow-up. Mean time to bleeding cessation was 2.6 days. Side effects were infrequent and patient satisfaction was high. Injection of depo-medroxyprogesterone acetate 150 mg intramuscularly combined with 3 days of oral medroxyprogesterone acetate 20 mg every 8 hours for 9 doses is an effective outpatient therapy for acute abnormal uterine bleeding.

    To determine the frequency of anterolateral ligament (ALL) injury in patients with acute anterior cruciate ligament (ACL) rupture and to analyse its associated injury patterns. Ninety patients with acute ACL rupture for which MRI was obtained within 8 weeks after the initial trauma were retrospectively identified. Two radiologists assessed the status of the ALL on MRI by consensus. The presence or absence of an ALL abnormality was compared with the existence of medial and lateral meniscal tears diagnosed during arthroscopy. Associated collateral ligament and osseous injuries were documented with MRI. Forty-one of 90 knees (46 %) demonstrated ALL abnormalities on MRI. Of 49 knees with intact ALL, 15 (31 %) had a torn lateral meniscus as compared to 25 torn lateral menisci in 41 knees (61 %) with abnormal ALL (p = 0.008). Collateral ligament (p ≤ 0.05) and osseous injuries (p = 0.0037) were more frequent and severe in ALL-injured as compared with ALL-intact knees. ALL injuries are fairly common in patients with acute ACL rupture and are statistically significantly associated with lateral meniscal, collateral ligament and osseous injuries. (orig.)

    Reduced executive control is one of the central components of model on the development and maintenance of Internet gaming disorder (IGD). Among the various executive control problems, high impulsivity has consistently been associated with IGD. We performed voxel-based morphometric analysis with diffeomorphic anatomical registration by using an exponentiated Lie algebra algorithm (DARTEL) to investigate the relationship of gray matter abnormalities to impulsivity in IGD. Thirty-one young male adults whose excessive Internet gaming began in early adolescence, and 30 age-matched male healthy controls were examined. IGD subjects showed smaller gray matter volume (GMV) in brain regions implicated in executive control, such as the anterior cingulate cortex and the supplementary motor area. The GMVs in the anterior cingulate cortex and the supplementary motor area were negatively correlated with self-reporting scales of impulsiveness. IGD subjects also exhibited smaller GMV in lateral prefrontal and parietal cortices comprising the left ventrolateral prefrontal cortex and the left inferior parietal lobule when compared with healthy controls. The GMVs in the left ventrolateral prefrontal cortex were negatively correlated with lifetime usage of Internet gaming. These findings suggest that gray matter abnormalities in areas related to executive control may contribute to high impulsivity of young adults with IGD. Furthermore, alterations in the prefrontal cortex were related with long-term excessive Internet gaming during adolescence. © 2017 Society for the Study of Addiction.

    MR imaging of the femoral marrow was performed in 36 patients with untreated acute myeloid leukemia (AML) and 7 patients with acute lymphocytic leukemia (ALL). The MRI appearance was classified into five patterns: fatty marrow; faint signal; nodular pattern; heterogeneous infiltration; and diffuse infiltration. The MRI patterns of the femoral marrow were compared among the FAB subtypes of acute leukemia, and the MRI patterns were correlated with prognosis. All five MRI patterns were observed in the femoral marrow in adult acute leukemia, and diffuse infiltration was most commonly seen (41.9%). A completely fatty marrow was also depicted in two cases (4.7%) and faint signal in four cases (9.3%) in spite of untreated acute leukemia. The M2 subtype of AML tended to be demonstrated as a minimally abnormal MRI finding, which was significantly different from the other types of AML. The patients who showed fatty marrow or faint signal were thought to have a good prognosis, while diffuse or heterogeneous infiltration was regarded as a poor prognostic sign. However, there were some exceptions to these rules, and no significant differences were revealed in prognosis between minimally abnormal and advanced MRI patterns. We concluded that MRI of the femoral marrow could be useful in the assessment of tumor volume of adult acute leukemia, and that there were limitations to predicting prognosis on the basis of the MRI manifestations.

    Background Accurate detection of recurrent chromosomal abnormalities is critical to assign patients to risk-based therapeutic regimens for pediatric acute lymphoblastic leukemia (ALL). Procedure We investigated the utility of array comparative genomic hybridization (aCGH) for detection of chromosomal abnormalities compared to standard clinical evaluation with karyotype and fluorescent in-situ hybridization (FISH). Fifty pediatric ALL diagnostic bone marrows were analyzed by bacterial artificial chromosome (BAC) array, and findings compared to standard clinical evaluation. Results Sensitivity of aCGH was 79% to detect karyotypic findings other than balanced translocations, which cannot be detected by aCGH because they involve no copy number change. aCGH also missed abnormalities occurring in subclones constituting less than 25% of cells. aCGH detected 44 additional abnormalities undetected or misidentified by karyotype, 21 subsequently validated by FISH, including abnormalities in 4 of 10 cases with uninformative cytogenetics. aCGH detected concurrent terminal deletions of both 9p and 20q in three cases, in two of which the 20q deletion was undetected by karyotype. A narrow region of loss at 7p21 was detected in two cases. Conclusions An array with increased BAC density over regions important in ALL, combined with PCR for fusion products of balanced translocations, could minimize labor- and time-intensive cytogenetic assays and provide key prognostic information in the approximately 35% of cases with uninformative cytogenetics.

    Increasing evidence suggests that regular moderate exercise increases neurogenesis in the dentate gyrus (DG) of the hippocampus and improves memory functions in both humans and animals. The DG is known to play a role in pattern separation, which is the ability to discriminate among similar experiences, a fundamental component of episodic memory. While long-term voluntary exercise improves pattern separation, there is little evidence of alterations in DG function after an acute exercise session. Our previous studies showing acute moderate exercise-enhanced DG activation in rats, and acute moderate exercise-enhanced prefrontal activation and executive function in humans, led us to postulate that acute moderate exercise may also activate the hippocampus, including more specifically the DG, thus improving pattern separation. We thus investigated the effects of a 10-min moderate exercise (50% V̇O 2peak ) session, the recommended intensity for health promotion, on mnemonic discrimination (a behavioral index of pattern separation) in young adults. An acute bout of moderate exercise improved mnemonic discrimination performance in high similarity lures. These results support our hypothesis that acute moderate exercise improves DG-mediated pattern separation in humans, proposing a useful human acute-exercise model for analyzing the neuronal substrate underlying acute and regular exercise-enhanced episodic memory based on the hippocampus. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Inattention is the most important behavioral feature of adult patients with attention-deficit/hyperactivity disorder (ADHD). Neuroimaging studies in ADHD have demonstrated abnormalities primarily in the frontostriatal circuitry and were mostly conducted in children. We investigated white matter (WM) integrity in adult ADHD patients and the correlation of WM microstructure and neuropsychological parameters in 37 (21 men) never-medicated adult ADHD patients and 34 age- and gender-matched healthy controls. All subjects underwent clinical interviews, rating scales, and neuropsychological tests of attentional performance. Diffusion tensor imaging (DTI) was acquired, and 12 WM regions-of-interest (ROIs) within the attentional network were chosen. Group differences of mean fractional anisotropy (FA) and mean diffusivity (MD) values were calculated for each ROI, and patients' DTI measures were then correlated with measures of attentional performance. FA values in ADHD patients were significantly reduced in the left inferior longitudinal fasciculus (ILF), while MD values were significantly increased in ADHD patients in the frontal portion of the left frontooccipital fasciculus (IFO). In ADHD patients, MD values were negatively correlated with attentional performance in the left ILF. Our findings provide further support for disturbed frontostriatal structural connectivity and also point to an involvement of the left temporal white matter with an impact on attentional performance.

    Full Text Available Neural network-based investigations of stuttering have begun to provide a possible integrative account for the large number of brain-based anomalies associated with stuttering. Here we used resting-state EEG to investigate functional brain networks in adults who stutter (AWS. Participants were 19 AWS and 52 age-, and gender-matched normally fluent speakers. EEGs were recorded and connectivity matrices were generated by LORETA in the theta (4–8 Hz, alpha (8–12 Hz, beta1 (12–20 Hz, and beta2 (20–30 Hz bands. Small-world propensity (SWP, shortest path, and clustering coefficients were computed for weighted graphs. Minimum spanning tree analysis was also performed and measures were compared by non-parametric permutation test. The results show that small-world topology was evident in the functional networks of all participants. Three graph indices (diameter, clustering coefficient, and shortest path exhibited significant differences between groups in the theta band and one [maximum betweenness centrality (BC] measure was significantly different between groups in the beta2 band. AWS show higher BC than control in right temporal and inferior frontal areas and lower BC in the right primary motor cortex. Abnormal functional networks during rest state suggest an anomaly of DMN activity in AWS. Furthermore, functional segregation/integration deficits in the theta network are evident in AWS. These deficits reinforce the hypothesis that there is a neural basis for abnormal executive function in AWS. Increased beta2 BC in the right speech–motor related areas confirms previous evidence that right audio–speech areas are over-activated in AWS. Decreased beta2 BC in the right primary motor cortex is discussed in relation to abnormal neural mechanisms associated with time perception in AWS.

    2013-01-01

    Acute epiglottitis is an acute inflammation in the supraglottic region of the oropharynx which is a potentially life-threatening condition leading to rapid upper airway obstruction. An infrequent sequel of acute epiglottitis is the epiglottic abscess. Less than 50 cases have been reported in the international literature and even less are the cases that acute surgical intervention was necessary to secure the airway. We report a young man with sudden onset of odynophagia, dysphonia and dyspnea and rapidly progression of upper airway obstruction. Clinical examination with fiberoptic nasopharyngolaryngoscope in emergency department demonstrated an epiglottic abscess. An urgent tracheostomy was performed in order to secure patient's airway and afterward, the patient underwent direct laryngoscopy and drainage of abscess and intravenous antibiotics were administrated. The diagnosis of epiglottic abscess should be considered in adult patients with odynophagia and dysphonia. Principles of treatment include aggressive airway management, surgical drainage of abscess and intravenous antibiotics. (author)

    2015-08-01

    this research aimed to characterize the daily eating behavior in a sample of Chilean adults according to their Body Mass Index (BMI) and gender and to analyze the possible links between these variables and abnormal eating behaviors. 657 participants (437 women and 220 men, age range 18-64 years) were evaluated with a battery of self-administered questionnaires. Mean BMI was 25.50 kg/m2 (women 24.96 kg/m2, men 26.58 kg/m2), being significantly higher the mean of BMI in the men group, being the BMI mean of the total sample and that of the male group in the overweight range. participants with overweight (BMI ≥ 25 kg/m2), in contrast with normal-weight group, tended to do more frequently the following behaviors: skip meals, follow a diet, eat less homemade food, eat faster and in greater quantities, in addition to do a greater number of abnormal eating behaviors of various kinds and to rate significantly higher in clinical scales that evaluated eating restraint and overeating. Men showed significantly more eating behaviors linked with overeating, and women performed more behaviors related with eating restraint and emotional eating. the results suggest that, besides "what" people eat, "how" people eat, in terms of specific behaviors, may contribute to the rapid increase of overweight in Chilean population.

    1981-01-01

    Radiographic findings of the upper and lower jaw bone of 20 adult patients with micrognathia, bird face, and juvenile rheumatoid arthritis are reported. In all patients a symmetrically underdeveloped mandible with the chin posteriorly positioned was found at cephalometry. Arthritic lesion of the temporomandibular joint, mostly symmetric, with limitation of movement and secondary arthrosis, was observed in all patients. Complete absence of the mandibular head was frequent (75%). The fossa was generally flat, probably due to growth disturbance of the tubercle. Abnormal anterior position of the mandibular head occurred in almost half of the patients. The degree of mandibular growth disturbance seemed to be correlated to the severity of the arthritis, indicating the arthritis to be a causal mechanism of micrognathia.

  12. Spectrum of congenital mitral valve abnormalities associated with solitary undifferentiated papillary muscle in adults.

    Mohan, Jagdish C; Shukla, Madhu; Mohan, Vishwas; Sethi, Arvind

    Congenital anomaly wherein the mitral valve leaflets are directly attached to the papillary muscle(s) (PM) with or without short under-developed chords is rarely reported in adults. Patients with two PMs with an intervening fibrous bridge have also been included under this head in previous studies. Echocardiography enables accurate evaluation of the morphology and function of valve leaflets, chordae tendineae, and PM. This report describes a series of six patients aged 56-84 years who had abnormal mitral valve with a large solitary and anomalously inserted PM seen over a period of 3 years. Only those patients who had a single pillar or bridge-like PM and either absent tendinous chords or small under-developed chords were included in the analysis. Among 9600 consecutive echocardiograms performed, six patients met the criteria of an abnormal mitral valve with solitary large PM. Two patients underwent mitral valve replacement with partial excision of the PM wherein echocardiographic observations were confirmed. The patients were previously followed with the diagnosis of hypertrophic cardiomyopathy (3) and rheumatic mitral valve disease (3). Multi-planar reconstruction of 3D echocardiographic images provided incremental value in assessing the detailed patho-anatomy of PMs in these cases. In adult patients, a high index of suspicion is required to detect congenital mitral stenosis/regurgitation with large solitary PM (resembling a parachute mitral valve) which may masquerade as hypertrophic cardiomyopathy or rheumatic mitral valve disease.

    Full Text Available BACKGROUND: Subjects with Attention-Deficit Hyperactivity Disorder (ADHD are overdistractible by stimuli out of the intended focus of attention. This control deficit could be due to primarily reduced attentional capacities or, e. g., to overshooting orienting to unexpected events. Here, we aimed at identifying disease-related abnormalities of novelty processing and, therefore, studied event-related potentials (ERP to respective stimuli in adult ADHD patients compared to healthy subjects. METHODS: Fifteen unmedicated subjects with ADHD and fifteen matched controls engaged in a visual oddball task (OT under simultaneous EEG recordings. A target stimulus, upon which a motor response was required, and non-target stimuli, which did not demand a specific reaction, were presented in random order. Target and most non-target stimuli were presented repeatedly, but some non-target stimuli occurred only once ('novels'. These unique stimuli were either 'relative novels' with which a meaning could be associated, or 'complete novels', if no association was available. RESULTS: In frontal recordings, a positive component with a peak latency of some 400 ms became maximal after novels. In healthy subjects, this novelty-P3 (or 'orienting response' was of higher magnitude after complete than after relative novels, in contrast to the patients with an undifferentially high frontal responsivity. Instead, ADHD patients tended to smaller centro-parietal P3 responses after target signals and, on a behavioural level, responded slower than controls. CONCLUSION: The results demonstrate abnormal novelty processing in adult subjects with ADHD. In controls, the ERP pattern indicates that allocation of meaning modulates the processing of new stimuli. However, in ADHD such a modulation was not prevalent. Instead, also familiar, only context-wise new stimuli were treated as complete novels. We propose that disturbed semantic processing of new stimuli resembles a mechanism for

    Molecular and cytogenetic studies performed in 305 adult acute lymphoblastic leukaemia (ALL) patients enrolled in the gimema (Gruppo Italiano Malattie EMatologiche dell'Adulto) multicentric protocols identified an E2A-PBX1 fusion and/or t(1;19) in 10 patients (3.3%). All had common ALL, were mostly CyIg+ and were CD34/CD13/CD33-. Nine patients achieved a complete remission (CR); five patients showed a haematological relapse after 7 months (median). Four patients are alive in first CR with a median follow-up of 29 months; three patients are molecularly negative. This abnormality is frequently associated with early treatment failure. E2A-PBX1+ adult ALL should be considered for intensified treatment strategies and monitoring of minimal residual disease.

  15. Acute behavioral symptomatology at disappearance of epileptiform EEG abnormality. Paradoxical or "forced" normalization.

    Wolf, P

    1991-01-01

    Paradoxical or "forced" normalization of the EEG of patients with epilepsy was first described by Landolt in 1953. It refers to conditions where disappearance of epileptiform discharge from the routine scalp EEG is accompanied by some kind of behavioral disorder. The best known of these is a paranoid psychotic state in clear consciousness, which is also known as "alternative" psychosis. Thus, the issue is related to much older observations which indicated a "biological antagonism" between productive psychotic symptomatology and epileptic seizures, which led to the therapy of psychoses with artificially induced convulsions. Apart from psychotic episodes, the clinical manifestations of PN comprise dysphoric states, hysterical and hypochondriacal syndromes, affective disorders, and miscellanea. PN can be observed in both generalized and localization-related epilepsies as a rare complication. A subset where it is more frequently seen are in adults with persistent absence seizures when the latter become finally controlled by succinimide therapy. These seem to be the drugs with the highest hazard of precipitation of PN, but all other AEDs have also been suspected. Sleep disturbance by succinimide treatment may play a crucial role, but a variety of other factors are also involved, including psychosocial factors. The pathogenesis of this condition has given rise to some debate but remains still unresolved. Eleven of the most important hypotheses have been discussed and seem to converge into a more comprehensive hypothesis which basically assumes that, during PN, the epilepsy is still active subcortically, perhaps with spread of discharge along unusual pathways. This activity is supposed to provide energy and, possibly, some of the symptoms included in the psychotic syndrome. A critical clinical condition results, usually with a dysphoric symptomatology, where a development towards psychosis is impending but still depends on the presence or absence of a variety of risk

    Genomic landscapes of 92 adult and 111 pediatric patients with B-cell acute lymphoblastic leukemia (B-ALL) were investigated using next-generation sequencing and copy number alteration analysis. Recurrent gene mutations and fusions were tested in an additional 87 adult and 93 pediatric patients. Among the 29 newly identified in-frame gene fusions, those involving MEF2D and ZNF384 were clinically relevant and were demonstrated to perturb B-cell differentiation, with EP300-ZNF384 inducing leukemia in mice. Eight gene expression subgroups associated with characteristic genetic abnormalities were identified, including leukemia with MEF2D and ZNF384 fusions in two distinct clusters. In subgroup G4 which was characterized by ERG deletion, DUX4-IGH fusion was detected in most cases. This comprehensive dataset allowed us to compare the features of molecular pathogenesis between adult and pediatric B-ALL and to identify signatures possibly related to the inferior outcome of adults to that of children. We found that, besides the known discrepancies in frequencies of prognostic markers, adult patients had more cooperative mutations and greater enrichment for alterations of epigenetic modifiers and genes linked to B-cell development, suggesting difference in the target cells of transformation between adult and pediatric patients and may explain in part the disparity in their responses to treatment.

    Acute promyelocytic leukemia (APL) is usually associated with a favorable outcome, but about 10% of patients tend to relapse. The genetic hallmark of APL is a balanced translocation involving chromosomes 15 and 17, and the PML-RARa gene fusion is found in more than 90% of these cases. Other chromosomal abnormalities are commonly found in APL, but their clinical significance has yet to be determined. Here we report a case of childhood APL that was studied by conventional cytogenetics along with molecular cytogenetic techniques. The patient showed a complex karyotype with an unusual cytogenetic rearrangement originating from two different abnormalities in a single chromosome 6. Our case is an exceptional example of a cryptic cytogenetic anomaly in APL and underscores the importance of detailed genetic characterization. Copyright © 2013 S. Karger AG, Basel.

    Few studies have used MRI to identify the ALL. As it was shown that it is not possible to precisely characterize this ligament in all examination, it is important to identify concomitant lesions that can help in diagnosing ALL abnormalities. It is important to characterise this injury due to its association with anterolateral knee instability. Thus, the present study was performed to determine the frequency of ALL injuries in patients with acute ACL rupture and to analyse its associated knee lesions. Patients with acute ACL injuries were evaluated by MRI. Among this population, the ALL was classified as non-visualised, injured or normal. The possible abnormalities of the meniscus, collateral ligaments, popliteus tendon, posterior cruciate ligament, Iliotibial band (ITB), anterolateral capsule and osseus injuries were evaluated. The association of an ALL injury with these other knee structures as well as sex and age was calculated. Among the 228 knees evaluated, the ALL could not be entirely identified in 61 (26.7%). Of the remaining 167, 66 (39.5%) presented an ALL abnormality and only four (6.1%) were Segond fractures. ALL abnormalities were associated with lesions of the lateral collateral ligament, medial collateral ligament, popliteus tendon, ITB, anterolateral capsule and osseous contusions of the femoral condyle and tibial plateau. No correlation was found with medial meniscus, lateral meniscus and posterior cruciate ligament injuries. There was no association between ALL injuries and gender, and older patients were more likely to present an ALL injury. ALL injuries are present in approximately 40% of ACL injuries, and a minority of these are Segond fractures. These injuries are associated with peripheral ligament injuries, anterolateral structures lesions and bone contusions, but there is no association with meniscal injuries. Surgeons must be aware of these associations to consider an ALL lesion even if it is not completely clear in imaging evaluation

    Full Text Available Here, we report a case of a 51-year-old man with acute pericardial tamponade requiring emergency pericardiocentesis after he suffered from sore throat, headache, malaise, and sweats for two weeks. Serological analyses revealed increased mumps IgM and IgG indicating an acute mumps infection whereas other bacterial and viral infections were excluded. In addition, MRI revealed atypical swelling of the left submandibular gland. Whereas mumps has become a rare entity in children due to comprehensive vaccination regimens in western civilizations, our case highlights mumps as an important differential diagnosis also in adults, where the virus can induce life-threatening complications such as pericardial tamponade.

    The Developmental Origins of Health and Disease (DOHaD) Theory proposes that the environment encountered during fetal life and infancy permanently shapes tissue physiology and homeostasis such that damage resulting from maternal stress, poor nutrition or exposure to environmental agents may be at the heart of adult onset disease. Interference with endogenous developmental functions of the aryl hydrocarbon receptor (AHR), either by gene ablation or by exposure in utero to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), a potent AHR ligand, causes structural, molecular and functional cardiac abnormalities and altered heart physiology in mouse embryos. To test if embryonic effects progress into an adult phenotype, we investigated whether Ahr ablation or TCDD exposure in utero resulted in cardiac abnormalities in adult mice long after removal of the agent. Ten-months old adult Ahr-/- and in utero TCDD-exposed Ahr+/+ mice showed sexually dimorphic abnormal cardiovascular phenotypes characterized by echocardiographic findings of hypertrophy, ventricular dilation and increased heart weight, resting heart rate and systolic and mean blood pressure, and decreased exercise tolerance. Underlying these effects, genes in signaling networks related to cardiac hypertrophy and mitochondrial function were differentially expressed. Cardiac dysfunction in mouse embryos resulting from AHR signaling disruption seems to progress into abnormal cardiac structure and function that predispose adults to cardiac disease, but while embryonic dysfunction is equally robust in males and females, the adult abnormalities are more prevalent in females, with the highest severity in Ahr-/- females. The findings reported here underscore the conclusion that AHR signaling in the developing heart is one potential target of environmental factors associated with cardiovascular disease.

    The prevalence of diabetes mellitus (DM) is reportedly growing fast in sub-Saharan Africa. There is however a scarcity of epidemiologic data on DM in Burkina Faso. We carried out a secondary analysis of the first survey conducted in Burkina Faso on a nationally representative sample following the World Health Organization (WHO) Stepwise approach to risk factors Surveillance (STEPS) for non-communicable diseases (NCDs) with the aims of identifying the prevalence of NCDs and the prevalence of common risk factors for NCDs. We report here on the prevalence of diabetes and overall abnormal glucose regulation (AGR) and their associated risk factors. In the primary study 4800 individuals were randomly sampled using a stratified multistage clusters sampling process. We used fasting capillary whole blood glucose level to define three glucose regulation statuses using WHO's cut-off levels: normal, diabetes and overall abnormal glucose regulation (impaired fasting glucose and diabetes). Appropriate statistical techniques for the analysis of survey data were used to identify the factors associated with diabetes and abnormal glucose regulation fitting a logistic regression model. Analyses were carried out using Stata Version 14 software. The prevalence of DM and AGR were respectively 5.8% (95% CI: 5-6.7) and 9% (95% CI: 8-10.1). Significant risk factors for DM include age (OR = 1.9; P = 0.009 for the age group of 55-64), obesity (OR: 2.6; P = 0.001), former smoke (OR:2; P = 0.03), second-hand smoke (OR = 1.7; P = 0.006) and total cholesterol level (OR: 2.1; P = 0.024). The same predictors were also found significantly associated with AGR. In addition, having an history family diabetes was protective against AGR (OR = 0.5; P = 0.032). Diabetes is no longer a rare disease in the adult active population of Burkina Faso. Its burden is significant in both rural and urban areas.

    Full Text Available BACKGROUND Bronchiectasis is defined as “abnormal and permanent dilatation of one or more bronchi due to weakening or destruction of the muscular and elastic components of the bronchial walls.” HRCT has become the gold standard to diagnose bronchiectasis. Antibiotics and chest physiotherapy are main forms of management. The aim of the study is to study the outcome of treatment in acute exacerbation of bronchiectasis in adults. MATERIALS AND METHODS This study was done prospectively in the Department of Respiratory Medicine in Rajarajeswari Medical College and Hospital from November 1, 2015, to April 30, 2017. Out of 55 cases admitted during the study period, 44 cases (10 females were eligible for participation in the study. 2 cases of Kartagener’s syndrome under follow up in our department for past 3 years were included. Flexible bronchoscopy was done in 31 patients. RESULTS Cough with sputum was the commonest symptom. Breathlessness was documented in 32 patients. Arterial blood gas analysis was abnormal in 29 patients. Haemoptysis in 13 cases. History of antituberculous therapy was present in 34 patients. Digital clubbing was present in 30 patients. Pedal oedema was documented in 14 cases. Associated cultures were positive in 28 cases. CONCLUSION The most frequent form of bronchiectasis is post-tuberculous. Pseudomonas aeruginosa is the most frequently isolated bacteria. The most frequent concomitant disease in bronchiectasis is COPD. Piperacillin/tazobactum is the most effective antibiotic for initial empirical treatment of acute exacerbations of bronchiectasis.

    A 58-year old woman had felt some chest pains on effort for several days. She was admitted to the emergency room with severe and refractory chest pain after exercise. Electrocardiogram showed marked ST-segment elevations in II, III, aVF and V1-6 electrodes. Echocardiogram revealed neither wall motion asynergy in the left ventricle nor abnormal pericardial effusion. Chest X-ray showed normal findings, and mild elevation of C-reactive protein was observed in the blood chemistry data. Her chest pain was relieved by nitroglycerin administration. Emergent technetium-99m-tetrofosmin myocardial imaging did not show any abnormal perfusion in the left ventricle. However, an abnormal extra-cardiac mediastinal accumulation was detected in the planar image. Contrast-enhanced chest CT scanning also demonstrated an inhomogeneously enhanced tumor in the anterior superior mediastinum. The tumor was surgically removed and was finally diagnosed as an invasive thymoma. Technetium-99m-tetrofosmin scintigraphy happened to provide useful information for diagnosing acute pericarditis with mediastinal tumor.

    2016-12-01

    Full Text Available Introduction. Nowadays acute infectious-inflammatory processes of upper respiratory tract, including acute epiglottitis retain a high proportion among human pathology. In the literature acute epiglottitis is allocated into an independent nosology as severe acute phlegmonous bacterial inflammation of the epiglottis and hypopharynx. There are currently no clear guidelines on how to classify an acute epiglottitis, as well as protocols for patients at various stages of the pathological process. According to common belief, Haemophilus influenzae type -B (Haemophilus influenza type b (Hib is the most common cause of epiglottitis. At present, the main etiological role in the genesis of acute epiglottitis in children belongs to haemophilus influenzae. In adults the causes of the disease are beta hemolytic streptococci groups A, B, pneumococcus, Klebsiella, Pseudomonas, Staphylococcus aureus, herpes simplex virus (type 1 and parainfluenza, and others.The aim of this work is to study: the mucosal microflora of the epiglottis in adult patients with acute epiglottitis and to study sensitivity of certain isolates to antimicrobial agents. Material & methods. 86 adult patients with acute epiglottitis were observed: 36 with abscess form of epiglottitis and 50 - with infiltrative. Microbiological analysis of mucosal swab samples taken from hypopharynx were conducted by the conventional technology: for seeding solid or liquid nutrient medium, followed by allocation of isolith and its microscopic, biochemical and serological identification. Microorganisms were classified according to schemes of Bergy. Antimicrobial susceptibility of each strain was determined in accordance with the guidelines. We used discs with antibacterial drugs. The availability of sensitive and resistant strains of microorganisms to antibiotics was assessed. A mucous membrane of the epiglottis was analyzed through microbiological investigation in 86 patients with acute epiglottitis. As a

    The aims of the current study were to determine whether patients with conduct disorder (CD) showed an abnormal availability of serotonin reuptake transporter (SERT), and if their hyperkinetic symptoms, impulsivity, and quality of life were correlated with the availability of SERT. We recruited 14 drug-naïve patients with CD and eight age-matched healthy controls (HCs). The adult attention-deficit/hyperactivity disorder (ADHD) self-report scale (ASRS), Barrett impulsivity scale (BIS), and the World Health Organization quality of life-brief version (WHOQOL-BREF) scale were administered. Positron emission tomography (PET) of the brain with 4-[ 18 F]-ADAM was arranged for SERT imaging. SERT availability was significantly reduced in the striatum and midbrain of patients with CD. Quality of life and inattention symptoms were also significantly correlated with the availability of SERT in the prefrontal cortex. The study suggested that a reduction in the availability of SERT might be associated with CD and could potentially predict poor quality of life or symptoms of inattention for these patients. The implications of our results might be limited to individuals with CD; a future study with a larger sample to validate our preliminary results is warranted. Copyright © 2016.

    The uncontrolled progression of the inflammatory cascade is the main cause underlying the development of multiple organ dysfunction syndrome (MODS) in acute pancreatitis. In this study, we investigated the effects of several immunosuppressants on mitigating the systemic inflammatory reaction syndrome (SIRS) and the compensatory anti-inflammatory response syndrome (CARS) associated with acute pancreatitis. A total of 93 male Sprague Dawley rats were divided into 5 groups: group 1 was the sham group and group 2 underwent laparoscopic intrapancreatic duct injection of sodium taurocholate to induce pancreatitis. The remaining 3 groups were the same as group 2, with the addition of methylprednisolone, cyclophosphamide or methotrexate treatment (metastab, CTX or MTX groups, respectively). Following establishment of the acute pancreatitis model, the serum levels of inflammatory and anti-inflammatory cytokines in groups 2, 3, 4 and 5 were found to be significantly elevated. Following immunosuppressant administration, the levels of all inflammatory and anti-inflammatory cytokines investigated in groups 3, 4 and 5 were decreased compared to those in group 2. The pancreatic amylase levels and pancreatic wet weight (PWW) were also decreased in groups 3, 4 and 5 compared to those in group 2. Therefore, immunosuppressants may reduce inflammation-related cytokine levels in acute pancreatitis and relieve disease progression.

    Full Text Available All-trans retinoic acid combined to anthracycline-based chemotherapy is the standard regimen of acute promyelocytic leukemia. The advent of arsenic trioxide has contributed to improve the anti-leukemic efficacy in acute promyelocytic leukemia. The objectives of the current study were to evaluate if dual induction by all-trans retinoic acid and arsenic trioxide could accelerate the recovery of abnormality of coagulation and fibrinolysis in patients with acute promyelocytic leukemia.Retrospective analysis was performed in 103 newly-diagnosed patients with acute promyelocytic leukemia. Hemostatic variables and the consumption of component blood were comparably analyzed among patients treated by different induction regimen with or without arsenic trioxide.Compared to patients with other subtypes of de novo acute myeloid leukemia, patients with acute promyelocytic leukemia had lower platelet counts and fibrinogen levels, significantly prolonged prothrombin time and elevated D-dimers (P<0.001. Acute promyelocytic leukemia patients with high or intermediate risk prognostic stratification presented lower initial fibrinogen level than that of low-risk group (P<0.05. After induction treatment, abnormal coagulation and fibrinolysis of patients with acute promyelocytic leukemia was significantly improved before day 10. The recovery of abnormal hemostatic variables (platelet, prothrombin time, fibrinogen and D-dimer was not significantly accelerated after adding arsenic trioxide in induction regimens; and the consumption of transfused component blood (platelet and plasma did not dramatically change either. Acute promyelocytic leukemia patients with high or intermediate risk prognostic stratification had higher platelet transfusion demands than that of low-risk group (P<0.05.Unexpectedly, adding arsenic trioxide could not accelerate the recovery of abnormality of coagulation and fibrinolysis in acute promyelocytic leukemia patients who received all

    Full Text Available Adverse rearing conditions are considered a major factor in the development of abnormal behavior. We investigated the overall levels, the prevalence and the diversity of abnormal behavior of 18 adult former laboratory chimpanzees, who spent about 20 years single caged, over a two-year period following re-socialization. According to the onset of deprivation, the individuals were classified as early deprived (EDs, mean: 1.2 years or late deprived (LDs, mean: 3.6 years. The results are based on 187.5 hours of scan sampling distributed over three sample periods: subsequent to re-socialization and during the first and second year of group-living. While the overall levels and the diversity of abnormal behavior remained stable over time in this study population, the amplifying effects of age at onset of deprivation became apparent as the overall levels of abnormal behavior of EDs were far above those of LDs in the first and second year of group-living, but not immediately after re-socialization. The most prevalent abnormal behaviors, including eating disorders and self-directed behaviors, however, varied in their occurrence within subjects across the periods. Most important, the significance of social companionship became obvious as the most severe forms of abnormal behavior, such as dissociative and self-injurious behaviors declined.

Aim: To assess the metabolic and endocrine abnormalities in adult patients with SCA and evaluate left ventricular (LV systolic and diastolic functions compared with patients with no SCA and further study the relationship between serum levels of cortisol, free thyroxine (T4, and testosterone with serum ferritin. Materials and methods: The study was conducted on 82 patients with adult HbSS SCA compared with a sex- and age-matched control group. The serum levels of cortisol, parathyroid hormone (PTH, testosterone, thyroid-stimulating hormone (TSH, and free T4 were compared. Blood levels of hemoglobin, reticulocyte count, lactate dehydrogenase (LDH, calcium, alkaline phosphatase (ALP, vitamin D3, and ferritin were also compared. Pulsed Doppler echo was performed to evaluate the LV mass, wall thickness, and cavity dimensions with diastolic filling velocities of early (E and atria (A waves. Biometric data were analyzed as mean ± standard deviation between the two groups. Multiple regression analysis was performed between serum levels of ferritin as independent variable and testosterone, cortisol, and thyroid hormones. Results: A total of 82 adult patients with HbSS SCA were enrolled who had a mean age of 21±5.7 years, with 51 males (62%. Patients with SCA compared with the control group had significantly lower hemoglobin, body mass index, cortisol, vitamin D3, testosterone, and T4. Furthermore, there were significantly high levels of

    Seo, Yongsuk, Hayden D. Gerhart, Jeremiah Vaughan, Jung-Hyun Kim, and Ellen L. Glickman. Does acute normobaric hypoxia induce anapyrexia in adult humans? High Alt Med Biol. 18:185-190, 2017.-Exposure to hypoxia is known to induce a reduction in core body temperature as a protective mechanism, which has been shown in both animals and humans. The purpose of this study was to test if acute exposure to normobaric hypoxia (NH) induces anapyrexia in adult humans in association with decreased peripheral oxygen saturation (SpO 2 ). Ten healthy male subjects were seated in atmospheres of normobaric normoxia 21% (NN21), NH 17% (NH17), and 13% (NH13) O 2 for 60 minutes in a counterbalanced manner. Rectal temperature (Tre) was continuously monitored together with the quantification of metabolic heat production (MHP) and body heat storage (S). Baseline physiological measurements showed no differences between the three conditions. SpO 2 was significantly decreased in NH17 and NH13 compared with NN21 (p ≤ 0.001). Tre decreased following 60 minutes of resting in all conditions, but, independent of the conditions, showed no association between Tre and levels of hypoxic SpO 2 . There was also no significant difference in either MHP or S between conditions. The present results showed no evidence of hypoxia-induced anapyrexia in adult humans during 1 hour of resting after exposure to NH either at 13% or 17% O 2 .

    Full Text Available BACKGROUND: Thyroid hormones have a key role in both the developing and adult central nervous system and skeletal muscle. The thyroid gland produces mainly thyroxine (T4 but the intracellular concentrations of 3,5,3'-triiodothyronine (T3; the transcriptionally active hormone in the central nervous system and skeletal muscle are modulated by the activity of type 2 deiodinase (D2. To date no neurological syndrome has been associated with mutations in the DIO2 gene and previous studies in young and juvenile D2-knockout mice (D2KO did not find gross neurological alterations, possibly due to compensatory mechanisms. AIM: This study aims to analyze the motor phenotype of 3-and-6-month-old D2KO mice to evaluate the role of D2 on the motor system at adult stages in which compensatory mechanisms could have failed. RESULTS: Motor abilities were explored by validated tests. In the footprint test, D2KO showed an altered global gait pattern (mice walked slower, with shorter strides and with a hindlimb wider base of support than wild-type mice. No differences were detected in the balance beam test. However, a reduced latency to fall was found in the rotarod, coat-hanger and four limb hanging wire tests indicating impairment on coordination and prehensile reflex and a reduction of muscle strength. In histological analyses of cerebellum and skeletal muscle, D2KO mice did not present gross structural abnormalities. Thyroid hormones levels and deiodinases activities were also determined. In D2KO mice, despite euthyroid T3 and high T4 plasma levels, T3 levels were significantly reduced in cerebral cortex (48% reduction and skeletal muscle (33% reduction, but not in the cerebellum where other deiodinase (type 1 is expressed. CONCLUSIONS: The motor alterations observed in D2KO mice indicate an important role for D2 in T3 availability to maintain motor function and muscle strength. Our results suggest a possible implication of D2 in motor disorders.

    Heroin addiction is a severe relapsing brain disorder associated with impaired cognitive control, including deficits in attention allocation. The thalamus has a high density of opiate receptors and is critically involved in orchestrating cortical activity during cognitive control. However, there have been no studies on how acute heroin treatment modulates thalamic activity. In a cross-over, double-blind, vehicle-controlled study, 29 heroin-maintained outpatients were studied after heroin and placebo administration, while 20 healthy controls were included for the placebo condition only. Resting-state functional magnetic resonance imaging was used to analyze functional integration of the thalamus by three different resting state analysis techniques. Thalamocortical functional connectivity (FC) was analyzed by seed-based correlation, while intrinsic thalamic oscillation was assessed by analysis of regional homogeneity (ReHo) and the fractional amplitude of low frequency fluctuations (fALFF). Relative to the placebo treatment and healthy controls, acute heroin administration reduced thalamocortical FC to cortical regions, including the frontal cortex, while the reductions in FC to the mediofrontal cortex, orbitofrontal cortex, and frontal pole were positively correlated with the plasma level of morphine, the main psychoactive metabolite of heroin. Furthermore, heroin treatment was associated with increased thalamic ReHo and fALFF values, whereas fALFF following heroin exposure correlated negatively with scores of attentional control. The heroin-associated increase in fALFF was mainly dominated by slow-4 (0.027-0.073 Hz) oscillations. Our findings show that there are acute effects of heroin within the thalamocortical system and may shed new light on the role of the thalamus in cognitive control in heroin addiction. Future research is needed to determine the underlying physiological mechanisms and their role in heroin addiction. © 2015 Wiley Periodicals, Inc.

    Acute mesenteric ischemia (AMI) is a potentially life-threatening condition with an associated high mortality. Prompt diagnosis is crucial to achieve a favorable outcome. The radiologist plays a central role in the initial evaluation of a patient with suspected AMI. In this pictorial essay, we review the appropriate imaging evaluation of a patient with suspected AMI, and we review both the common and uncommon etiologies of mesenteric ischemia. With each etiology presented, relevant clinical and imaging findings, as well as potential treatments, are reviewed.

    Full Text Available Diarrhea is a global health problem with high morbidity and mortality. In developing countries, acute diarrhea is most commonly caused by infectious pathogens. Regardless of the cause, diarrhea is primarily treated by fluid replacement therapy to decrease the risk of dehydration and death, although it does not affect the duration of diarrhea. Probiotics are able to shorten the duration of diarrhea in children, but its efficacy in adults is unclear. This study aimed to evaluate the benefit of probiotic in reducing the duration of acute diarrhea in adults as compared to placebo. Systematic search was done using four databases: PubMed, Scopus, ProQuest, and Embase, without limit on the year of publication. Randomized clinical trials were selected as the appropriate study design to answer the clinical question and two studies were considered relevant for appraisal. In conclusion, probiotics could improve the recovery of acute infectious diarrhea in adults (level of evidence 1b however more studies should be carried out since only very few strains of probiotics have been investigated.

    Crohn's disease (CD) is a chronic, immune-mediated, inflammatory disorder of the intestine that has been linked to numerous susceptibility genes, including the immunity-related GTPase (IRG) M (IRGM). IRGs comprise a family of proteins known to confer resistance to intracellular infections through various mechanisms, including regulation of phagosome processing, cell motility, and autophagy. However, despite its association with CD, the role of IRGM and other IRGs in regulating intestinal inflammation is unclear. We investigated the involvement of Irgm1, an ortholog of IRGM, in the genesis of murine intestinal inflammation. After dextran sodium sulfate exposure, Irgm1-deficient [Irgm1 knockout (KO)] mice showed increased acute inflammation in the colon and ileum, with worsened clinical responses. Marked alterations of Paneth cell location and granule morphology were present in Irgm1 KO mice, even without dextran sodium sulfate exposure, and were associated with impaired mitophagy and autophagy in Irgm1 KO intestinal cells (including Paneth cells). This was manifested by frequent tubular and swollen mitochondria and increased LC3-positive autophagic structures. Interestingly, these LC3-positive structures often contained Paneth cell granules. These results suggest that Irgm1 modulates acute inflammatory responses in the mouse intestine, putatively through the regulation of gut autophagic processes, that may be pivotal for proper Paneth cell functioning.

    Abnormalities are not uncommon in Taenia saginata and T. solium. After examining 328 mature proglottids from 2 adult worms from two experimentally infected hamsters, 13 (4.0%) were found to have no genital pore but with numerous testes and several vas efferents; 1 (0.3%) one genital pore with one reproductive system; 12 (3.7%) one on each side with two sets of reproductive system; 17 (5.2%) two on one side with 2 sets of reproductive system; 8 (2.4%) one on one side and two on the other side with 3 sets of reproductive system; 2 (0.6%) two on each side with 4 sets of reproductive system; 4 (1.2%) three on one side with 3 sets of reproductive system, and 4 one on one side and three on the other side with 4 sets of reproductive system. Nine evaginated abnormal cysticerci of T. s. asiatica from three experimentally infected SCID mice each had two protoscoleces and a big bladder. From two experimentally infected pigs, one abnormal cysticercus was observed to have two invaginated canals each in one end. Another one had a neck-band behind the scolex and a big bladder. This paper is not only the first report of abnormality of T. solium from hamster but also the first one of abnormal cysticerci of T. s. asiatica from pigs and mice.

    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.

    Pericapitate involvement of the wrist has been described as characteristic of adult-onset Still disease, a relatively rare disorder that is often diagnosed by exclusion after extensive and frequently invasive tests. To evaluate the diagnostic value of carpal radiography in cases of adult-onset Still disease, a retrospective blinded analysis of 48 patients, 16 each with adult-onset Still disease, juvenile chronic arthritis, and rheumatoid arthritis, was performed. Pericapitate articular alterations without radiocarpal involvement were found to be frequent in the setting of adult-onset Still disease but distinctly unusual among patients with rheumatoid arthritis. In juvenile chronic arthritis, severe pericapitate involvement was frequent, but generally occurred in conjunction with radiocarpal joint abnormalities

    Herein, we describe a 61-year-old man diagnosed with pulmonary hemosiderosis following chemotherapy for acute adult T-cell leukemia/lymphoma (ATLL). Liver and heart biopsy confirmed hemosiderosis. ATLL progressed, and the patient died from multiorgan damage. Welder's lung may have been involved in hemosiderosis and systemic iron overload. Abnormal iron metabolism or immune reactions may have influenced the clinical course, but these were not validated. Detailed analyses of family medical and lifestyle histories, and genetic examination should be performed in cases of systemic iron overload.

    Full Text Available The primary objective of this review was to update and discuss the current concepts andthe results of the treatment of acute lymphoblastic leukemia (ALL in adolescents and young adults(AYA. After a brief consideration of the epidemiologic and clinicobiologic characteristics of ALLin the AYA population, the main retrospective comparative studies stating the superiority ofpediatric over adult-based protocols were reviewed. The most important prospective studies inyoung adults using pediatric inspired or pediatric unmodified protocols were also reviewedemphasizing their feasibility at least up to the age of 40 yr and their promising results, with eventfreesurvival rates of 60-65% or greater. Results of trials from pediatric groups have shown that theunfavourable prognosis of adolescents is no more adequate. The majority of the older adolescentswith ALL can be cured with risk-adjusted and minimal residual disease-guided intensivechemotherapy, without stem cell transplantation. However, some specific subgroups, which aremore frequent in adolescents than in children (e.g., early pre-T, iAMP21, and BCR-ABL-like,deserve particular attention. In summary, the advances in treatment of ALL in adolescents havebeen translated to young adults, and that explains the significant improvement in survival of thesepatients in recent years.

    B-cell acute lymphoblastic leukemia (B-ALL) accounts for 20-30% of acute leukemias in adults. Combined application of data from immunophenotyping, karyotyping and molecular analyses allows a better understanding of this heterogeneous disease. We studied 30 adult patients with newly diagnosed B-ALL by conventional cytogenetics, fluorescent in situ hybridization (FISH) and immunophenotyping analyses. We report statistically significant prevalence of structural aberrations (43%) over numerical changes (17%) (p=0.02). The most frequent structural changes were t(9;22)(q34;q11)/bcr-abl-17%, t(8q24)/C-MYC-10%, t(11q23)/MLL-6%, del 4p-6%, del12p-3%, and t(1;19)-3%. Complex karyotype was found in 17% and normal karyotype in 30%. The most frequent immunophenotype was of common B-ALL (43%), and cytogenetic and/or molecular abnormalities were found in 78% of them. We distinguished a relatively high incidence (17%) of mature B-ALL and 60% of them were associated with t(8;14)/C-MYC. We established association of cytogenetic aberrations with immunophenotype only in mature B-ALL. The other immunophenotypes are characterized by genetic heterogeneity and the presence of cytogenetic abnormalities unusual for adult B-ALL - trisomy 8 and t(1;19)(q23;p13).

    Rotavirus infection is the most common aetiology of acute gastroenteritis (AGE) among young children. In adults, diagnostics focus mainly on bacterial causes, though recent studies suggest that rotavirus is a frequent agent. The aim of this study was to examine the proportion of rotavirus in adults hospitalised with AGE and to identify possible predictors. During a 24-month period from 1 May 2010 adults (> 15 years) with AGE admitted to one of four hospitals in the Central Denmark Region were examined for rotavirus with VIKIA Rota-Adeno rapid test in addition to routine culture for bacterial pathogens. A total of 265 adult patients were included. 9.4% tested positive for rotavirus. Enteropathogenic bacteria were found in 24.5% of the cases. In the majority of cases (62.3%), no pathogen was found. Overall, rotavirus was the second-most frequent pathogen, exceeded only by Campylobacter spp. Immunosuppression and a C-reactive protein (CRP) below 50 mg/l (0-8 mg/l) were associated with rotavirus. The seasonality of rotavirus differed markedly from that of bacterial gastroenteritis. Rotavirus is the second-most frequently identified pathogen in adults hospitalised with AGE. Close contact to children or travel activity does not predict rotavirus gastroenteritis, but immunosuppression and a CRP below 50 mg/l do. The seasonality of rotavirus differs from that of bacterial gastroenteritis, making rotavirus the most frequently identified cause of AGE in adults admitted to hospital in the colder months. The trial was funded by an unrestricted grant from Sanofi Pasteur MSD. not relevant.

    Full Text Available Objective: To study the frequency of mutations that maylead to a good or bad prognosis, as well as their relation withthe karyotype and immunophenotype in patients with acutemyeloid leukemia. Methods: Thirty samples of patients withacute myeloid leukemia were studied, in which FLT3-ITD, FLT3-TKD and NPM1 mutations were investigated. All samples weresubmitted to immunophenotyping and 25 to karyotyping. Results:An occurrence of 33.3% NPM1 mutation and an equal numberof FLT3-ITD mutation were observed. When only the cases withnormal karyotype were studied, this figures increased to 50 and40%, respectively. Eight percent of cases with normal karyotypeand genotype NPM1+/FLT3- were included in the group of acutemyeloid leukemia with good prognosis. The typical phenotypeof acute myeloid leukemia with normal karyotype and mutatedNPM1 (HLA-DR and CD34 negative was not observed in thissmall series. Conclusion: Good prognosis cases were identifiedin this series, emphasizing the need to include new geneticmarkers in the diagnostic routine for the correct classification ofacute myeloid leukemia, to more properly estimate prognosis anddetermine treatment.

    To evaluate WHO classification of acute leukemia (AL) in Shanghai and compare the difference between WHO and FAB classification. Successive and unselected leukemia patients were referred to Sino-US Leukemia Cooperative Group of Shanghai from 2003 to 2006. A total of 572 adult AL cases were diagnosed and classified according to WHO and FAB classification. Of the 572 AL patients, 436 (76.2%) were diagnosed as acute myeloid leukemia (AML), 119 (20.8%) acute lymphoblastic leukemia (ALL). The AML and ALL percentage ratio was 3.66: 1. AML with recurrent cytogenetic abnormalities accounted for 35.3%, and with multilineage dysplasia for 13.1%, therapy-related AML accounted for 0.9%, and AML not otherwise categorized for 50.7%. The percentage of therapy-related AML in Shanghai was lower than that in the Western. B-ALL was the majority (84.9%) in ALL. According to FAB classification, AML-M4 was the most (38.5%) common subtype. The percentage of AML-M3 and M4 in Shanghai were higher than that in the Western, but that of AML-M, was lower. The incidence of karyotypic abnormalities in AML was 60.8%. The incidence of AML with t (15;17) was higher than that in the Western. Favorable cytogenetic risk group accounted for 30.6%, intermediate group for 51.5%, unfavorable group for 17.9% of AML. B-ALL with t (9;22) was 33.7%. The percentages of AML with t (15;17) and AML-M4 in Shanghai and the incidence of cytogenetic favorable group were higher than that in the Western. It was different in WHO classification and karyotypic abnormalities of AML between Shanghai and the Western. Comparing to the AL data of Shanghai Leukemia Group between 1984 and 1994, the percentage of AML-M4 was increased, but that of AML-M1 and M5 were decreased.

A review of the incidence, etiology, diagnoses, and treatment of AKI in adults in Africa from studies published between the years 2000 and 2015. The incidence of AKI in hospitalized patients in Africa ranges from 0.3 to 1.9% in adults. Between 70 and 90% of cases of AKI are community acquired. Most patients with AKI are young with a weighted mean age of 41.3 standard deviation (SD) 9.3 years, and a male to female ratio of 1.2 : 1.0. Medical causes account for between 65 and 80% of causes of AKI. This is followed by obstetric causes in 5 - 27% of cases and surgical causes in 2 - 24% of cases. In the reported studies, between 17 and 94% of patients who needed dialysis received this. The mortality of AKI in adults in Africa ranged from 11.5 to 43.5%. Most reported cases of AKI in Africa originate in the community. The low incidence of hospital-acquired AKI is likely to be due to under ascertainment. Most patients with AKI in Africa are young and have a single precipitating cause. Prominent among these are infection, pregnancy complications and nephrotoxins. Early treatment can improve clinical outcomes.

    Metabolic abnormalities and metabolic syndrome (MetS) increasingly have been linked to depression. The authors studied examined inpatients 35 years and older with major depressive disorder (MDD) to determine the prevalence of component metabolic abnormalities and the full MetS with age, treatment, and comorbid dementia. Data analysis involved retrospective cross-sectional review from a nonprofit psychiatry inpatient service of all discharges 35 years and older with a diagnosis of MDD during a 3 year period (April 1, 2003 to March 31, 2006) (N=1718). Metabolic measures included waist circumference, lipid measurements, glucose, and hypertension diagnosis. Abnormal metabolic measures and MetS were highly prevalent in both young and old patients with MDD: one or more component was present in 87.6% of older (65-99 years old) and 79.9% of younger patients. Full MetS was present in 31.5% of older and 28.9% of younger patients (not significant, P=0.85). Metabolic abnormalities were not associated with atypical antipsychotics after controlling other variables. One-quarter (n=79, 24.9%) of older inpatients had a dementia co-diagnosis. Older patients with MDD and dementia had greater risk of elevated glucose while younger patients were more often hypertensive. Longitudinal studies are needed to determine the relationships of MDD with or without dementia with these highly prevalent abnormal metabolic measures and MetS.

    Tenoxicam is a non-steroidal anti-inflammatory drug (NSAID) licensed for use in rheumatic disease and other musculoskeletal disorders in the UK, and is widely available in other countries worldwide. This review sought to evaluate the efficacy and safety of oral tenoxicam in acute postoperative pain, using clinical studies of patients with established pain, and with outcomes measured primarily over 6 hours using standard methods. This type of study has been used for many decades to establish that drugs have analgesic properties. To assess the efficacy of single dose oral tenoxicam in acute postoperative pain, and any associated adverse events. We searched The Cochrane Library (Issue 1, 2009), MEDLINE (March 2009); EMBASE via Ovid (March 2009); the Oxford Pain Relief Database. Randomised, double-blind, placebo-controlled clinical trials of oral tenoxicam for relief of acute postoperative pain in adults. Two review authors independently assessed trial quality and extracted data. The area under the "pain relief versus time" curve was used to derive the proportion of participants with tenoxicam experiencing least 50% pain relief over 4 to 6 hours, using validated equations. The number needed to treat to benefit (NNT) was calculated using 95% confidence intervals (CI). The proportion of participants using rescue analgesia over a specified time period, and time to use of rescue analgesia, were sought as additional measures of efficacy. Information on adverse events and withdrawals was also collected. Not one of sixteen studies identified by the searches and examined in detail studied oral tenoxicam in patients with established postoperative pain and therefore no results are available. In the absence of evidence of efficacy for oral tenoxicam in acute postoperative pain, its use in this indication is not justified at present. Because trials clearly demonstrating analgesic efficacy in the most basic of acute pain studies is lacking, use in other indications should be

    Despite improvements in our understanding of the molecular basis of acute myeloid leukemia, the association between genetic mutations with morphologic dysplasia remains unclear. In this study, we evaluated and scored dysplasia in bone marrow specimens from 168 patients with de novo acute myeloid leukemia; none of these patients had 2016 WHO Classification-defined cytogenetic abnormalities. We then performed targeted sequencing of diagnostic bone marrow aspirates for recurrent mutations associated with myeloid malignancies. We found that cohesin pathway mutations (q (FDR-adjusted p)=0.046) were associated with a higher degree of megakaryocytic dysplasia and STAG2 mutations were marginally associated with greater myeloid lineage dysplasia (q=0.052). Frequent megakaryocytes with separated nuclear lobes were more commonly seen among cases with cohesin pathway mutations (q=0.010) and specifically in those with STAG2 mutations (q=0.010), as well as NPM1 mutations (q=0.022 when considering the presence of any versus no megakaryocytes with separated nuclear lobes). RAS pathway mutations (q=0.006) and FLT3-ITD (q=0.006) were significantly more frequent in cases without evaluable erythroid cells. In univariate analysis of the 153 patients treated with induction chemotherapy, NPM1 mutations were associated with longer event-free survival (EFS, p=0.042), while RUNX1 (p=0.042), NF1 (p=0.040), frequent micromegakaryocytes (p=0.018) and presence of a subclone (p=0.002) were associated with shorter EFS. In multivariable modelling, NPM1 was associated with longer EFS, while presence of a subclone and frequent micromegakaryocytes remained significantly associated with shorter EFS.

    Unlike Burkitt lymphoma, molecular abnormalities other than C-MYC rearrangements have scarcely been studied in patients with mature B acute lymphoblastic leukemia (B-ALL). The aim of this study was to analyze the frequency and prognostic significance of copy number alterations (CNA) in genes involved in lymphoid differentiation, cell cycle and tumor suppression in adult patients with B-ALL. We have analyzed by multiplex ligation-dependent probe amplification the genetic material from bone marrow at diagnosis from 25 adult B-ALL patients treated with rituximab and specific chemotherapy. The most frequent CNA were alterations in the 14q32.33 region (11 cases, 44%) followed by alterations in the cell cycle regulator genes CDKN2A/B and RB1 (16%). No correlation between the presence of specific CNA and the clinical-biologic features or the response to therapy was found. The high frequency of CNA in the 14q32.33 region, CDKN2A/B and RB1 found in our study could contribute to the aggressiveness and invasiveness of mature B-ALL. Copyright © 2016 Elsevier España, S.L.U.

    To date, the literature on perception of affective, pragmatic, and grammatical prosody abilities in autism spectrum disorders (ASD) has been sparse and contradictory. It is interesting to note that the primary perception of syllable stress within the word structure, which is crucial for all prosody functions, remains relatively unexplored in ASD. Thus, in the current study, we explored syllable stress perception sensitivity and its relationship to speech production abnormalities and communicative ability in adults with ASD. A same-different syllable stress perception task using pairs of identical 4-syllable words was delivered to 42 adults with/without high-functioning ASD, matched for age, to investigate primary speech perception ability in ASD. Speech production and communicative ability in ASD was measured using the Autism Diagnostic Observation Schedule (Lord et al., 2000). As predicted, the results showed that adults with ASD were less sensitive in making judgments about syllable stress relative to controls. Also, partial correlations revealed a key association of speech production abnormalities with stress perception sensitivity, rather than communicative ability. Our findings provide empirical evidence for deficits on primary syllable stress perception in ASD and its role on sociocommunicative difficulties. This information could facilitate the development of effective interventions for speech and language therapy and social communication.

    Functional disturbances within cortico-striatal control systems have been implicated in the psychobiology (i.e. impaired cognitive-behavioral flexibility, perfectionist personality) of anorexia nervosa. The aim of the present study was to investigate the morphometry of brain regions within cortico-striatal networks in acute anorexia nervosa (AN) as well as long-term weight-restored anorexia nervosa (AN-WR) patients. A total of 39 participants: 12 AN, 13 AN-WR patients, and 14 healthy controls (HC) underwent high-resolution, T1-weighted magnetic resonance imaging (MRI), a cognitive-behavioral flexibility task, and a psychometric assessment. Group differences in local grey matter volume (GMV) were analyzed using whole brain voxel-based morphometry (VBM) and brain-atlas based automatic volumetry computation (IBASPM). Individual differences in total GMV were considered as a covariate in all analyses. In the regional brain morphometry, AN patients, as compared to HC, showed decreased GMVs (VBM and volumetry) in the anterior cingulate cortex (ACC), the supplementary motor area (SMA), and in subcortical regions (amygdala, putamen: VBM only). AN-WR compared to HC showed decreased GMV (VBM and volumetry) in the ACC and SMA, whereas GMV of the subcortical region showed no differences. The findings of the study suggest that structural abnormalities of the ACC and SMA were independent of the disease stage, whereas subcortical limbic-striatal changes were state dependent.

    Eye globe abnormalities can be readily detected on dedicated and non-dedicated CT and MR studies. A primary understanding of the globe anatomy is key to characterising both traumatic and non-traumatic globe abnormalities. The globe consists of three primary layers: the sclera (outer), uvea (middle), and retina (inner layer). The various pathological processes involving these layers are highlighted using case examples with fundoscopic correlation where appropriate. In the emergent setting, trauma can result in hemorrhage, retinal/choroidal detachment and globe rupture. Neoplasms and inflammatory/infective processes predominantly occur in the vascular middle layer. The radiologist has an important role in primary diagnosis contributing to appropriate ophthalmology referral, thereby preventing devastating consequences such as vision loss.

    Cocaine is a well known trigger of acute coronary syndromes. Over the last 10 years levamisole, a veterinary anthelminthic drug has been increasingly used as an adulterant of cocaine. Levamisole was used to treat pediatric nephritic syndrome and rheumatoid arthritis before being withdrawn from the market due to its significant toxicity, i.e. hematological complications and vasculitis. The major complications of levamisole-adultered cocaine reported up to now are hematological and dermatological. The case reported here is of a 25 year old man with a history of cocaine abuse who died at home after complaining of retrosternal pain. Postmortem CT-angiography, autopsy, and chemical and toxicological analyses were performed. An eroded coronary artery plaque was found at the proximal segment of the left anterior descending coronary artery. Two myocardial infarct scars were present in the left ventricle. Microscopic examination of the coronary artery revealed infiltration of eosinophils into the adventitia and intima. Toxicological examination confirmed the presence of cocaine and its metabolites in the peripheral blood, and of levamisole in the urine and pericardial fluid. Eosinophilic inflammatory coronary artery pathologies have been clinically linked to coronary dissection, hypersensitivity coronary syndrome and vasospastic allergic angina. The coronary pathology in the presented case could be a complication of levamisole-adultered cocaine use, in which an allergic or immune-mediated mechanism might play a role. The rise in cocaine addiction worldwide and the increase of levamisole adulterated cocaine highlights the importance of updating our knowledge of the effects of adultered cocaine abuse.

    Sleep abnormalities, including obstructive sleep apnea (OSA), have been associated with insulin resistance. To determine the relationship between sleep, including OSA, and glucose parameters in a prospectively assembled cohort of chronically sleep-deprived obese subjects. Cross-sectional evaluation of a prospective cohort study. Tertiary Referral Research Clinical Center. Sleep duration and quality assessed by actigraphy, sleep diaries and questionnaires, OSA determined by a portable device; glucose metabolism assessed by oral glucose tolerance test (oGTT), and HbA1c concentrations in 96 obese individuals reporting sleeping less than 6.5 h on a regular basis. Sixty % of subjects had an abnormal respiratory disturbance index (RDI≥5) and 44% of these subjects had abnormal oGTT results. Severity of OSA as assessed by RDI score was associated with fasting glucose (R = 0.325, p = 0.001) and fasting insulin levels (ρ = 0.217, p = 0.033). Subjects with moderate to severe OSA (RDI>15) had higher glucose concentrations at 120 min than those without OSA (RDIsleep deprived individuals. Since sleep apnea is common and frequently undiagnosed, health care providers should be aware of its occurrence and associated risks. This study was conducted under the NIDDK protocol 06-DK-0036 and is listed in ClinicalTrials.gov NCT00261898.

    Blast-induced neurotrauma (BINT), if not fatal, is nonetheless potentially crippling. It can produce a wide array of acute symptoms in moderate-to-severe exposures, but mild BINT (mBINT) is characterized by the distinct absence of acute clinical abnormalities. The lack of observable indications for mBINT is particularly alarming, as these injuries have been linked to severe long-term psychiatric and degenerative neurological dysfunction. Although the long-term sequelae of BINT are extensively documented, the underlying mechanisms of injury remain poorly understood, impeding the development of diagnostic and treatment strategies. The primary goal of this research was to recapitulate primary mBINT in rodents in order to facilitate well-controlled, long-term investigations of blast-induced pathological neurological sequelae and identify potential mechanisms by which ongoing damage may occur postinjury. A validated, open-ended shock tube model was used to deliver blast overpressure (150 kPa) to anesthetized rats with body shielding and head fixation, simulating the protective effects of military-grade body armor and isolating a shock wave injury from confounding systemic injury responses, head acceleration, and other elements of explosive events. Evans Blue-labeled albumin was used to visualize blood-brain barrier (BBB) compromise at 4 hours postinjury. Iba1 staining was used to visualize activated microglia and infiltrating macrophages in areas of peak BBB compromise. Acrolein, a potent posttraumatic neurotoxin, was quantified in brain tissue by immunoblotting and in urine through liquid chromatography with tandem mass spectrometry at 1, 2, 3, and 5 days postinjury. Locomotor behavior, motor performance, and short-term memory were assessed with open field, rotarod, and novel object recognition (NOR) paradigms at 24 and 48 hours after the blast. Average speed, maximum speed, and distance traveled in an open-field exploration paradigm did not show significant

    Myocardial involvement in young adults has various causes. Acute myopericarditis is one of the myocardial involvements in young adults. It is easy to confuse with acute ST-elevation myocardial infarction because of the electrocardiographic features. This study aims to investigate a number of imaging techniques and clinical features for acute myopericarditis in young adults (defined as myocardial brightness in the left ventricle regions, especially in posterior and lateral wall. Focal echobright was observed in the 75 of 77 cases of acute myopericarditis in transthoracic echocardiogram. This sign was confirmed by cardiac magnetic resonance imaging. Focal echobright sensitivity was 95%; its specificity was 93%; its predictive was 95.2%. Pericardial effusion (83%) was observed in group I behind posterior wall. Its specificity was 81%; its sensitivity was 65%; predictivity was 73%. Pericardial effusion and myocardial focal echobright in echocardiography can be quite sensitive indicators for acute myopericarditis in young adults.

    Acute postoperative pain is still an issue in patients undergoing abdominal surgery. Postoperative pain and side effects of analgesic treatment, in particular those of opioids, need to be minimized. Opioid-sparing analgesics, possibly including dexmedetomidine, seem a promising avenue by which to improve postoperative outcomes. Our primary aim was to determine the analgesic efficacy and opioid-sparing effect of perioperative dexmedetomidine for acute pain after abdominal surgery in adults.Secondary aims were to establish effects of dexmedetomidine on postoperative nausea and vomiting (PONV), gastrointestinal function and mobilization, together with the side effect profile of dexmedetomidine. We searched the following databases: Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, Institute for Scientific Information (ISI), Web of Science and Cumulative Index to Nursing and Allied Health Literature (CINAHL), and reference lists of articles to May 2014. We searched the Science Citation Index, ClinicalTrials.gov and Current Controlled Trials, and we contacted pharmaceutical companies to identify unpublished and ongoing studies. We applied no language restrictions. We reran the search in May 2015 and found nine studies of interest. We will deal with the studies of interest when we update the review. We included randomized, controlled trials of perioperative dexmedetomidine versus placebo or other drug during abdominal surgery in adults. Trials included one of the following outcomes: amount of 'rescue' opioid, postoperative pain, time to 'rescue' analgesia, participants requiring 'rescue' analgesia, postoperative sedation, PONV, time to first passage of flatus and stool or time to first out-of-bed mobilization. Two review authors independently screened the titles and abstracts for eligibility. We retrieved full trial reports if necessary, and we extracted relevant data from the included studies using a data collection form and assessed risk of bias. We

    Visual defects are common in deaf individuals. Refractive error and ocular motor abnormalities are frequently reported, with hyperopia, myopia, astigmatism and anomalies of binocular vision, all showing a greater prevalence in deaf individuals compared with the general population. Near visual function in deaf individuals has been relatively neglected in the literature to date. Comparisons between studies are problematic due to differences in methodology and population characteristics. Any untreated visual defect has the potential to impair the development of language, with consequences for education more generally, and there is a need to improve screening and treatments of deaf children. © 2013 Acta Ophthalmologica Scandinavica Foundation.

    Most tracheobronchial and parenchymatous congenital abnormalities of the respiratory system are diagnosed in early life. However, some lesions may be initially silent and diagnosed only in adulthood. These cases included congenital abnormalies of the tracheobronchial tract (tracheal and/or bronchial stenosis, bronchogenic cysts, bronchial atresia, oesotracheal fistula, oesobronchial fistula, and tracheal diverticulum), and lung parenchyma itself (pulmonary sequestration, congenital cystic adenomatoïd malformation, lobar emphysema, lobar or lung hypoplasia). To avoid dreadful complications, these rare cases deserve surgical management, and must be known by chest physicians and surgeons. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

  20. Reversible Stress Cardiomyopathy Presenting as Acute Coronary Syndrome with Elevated Troponin in the Absence of Regional Wall Motion Abnormalities: A Forme Fruste of Stress Cardiomyopathy?

    Full Text Available We present a case of reversible stress cardiomyopathy in a surgical patient, described here as a forme fruste due to its atypical features. It is important to recognize such unusual presentation of stress cardiomyopathy that mimics acute coronary syndrome. Stress cardiomyopathy commonly presents as acute coronary syndrome and is characterized by typical or atypical variants of regional wall motion abnormalities. We report a 60-year-old Caucasian male with reversible stress cardiomyopathy following a sternal fracture fixation. Although the patient had several typical features of stress cardiomyopathy including physical stress, ST-segment elevation, elevated cardiac biomarkers and normal epicardial coronaries, there were few features that were atypical, including unusual age, gender, absence of regional wall motion abnormalities, high lateral ST elevation, and high troponin-ejection fraction product. In conclusion, this could represent a forme fruste of stress cardiomyopathy.

    In the absence of direct toxins, the majority of evidence from animal models suggests that neutrophils (PMN) are necessary for the full expression of the abnormal pulmonary permeability accompanying acute microvascular lung injury. We therefore studied the role of the PMN in the human correlate of this disease, the adult respiratory distress syndrome (ARDS), by assessing the pulmonary retention of infused autologous 111 Indium-labeled PMN (PMN-In). We evaluated 79 patients, prospectively categorized as: active ARDS (Aa; n = 30), active ARDS and concurrent corticosteroid therapy (As; n = 11), resolving ARDS (Ar; n = 13), sepsis without pulmonary edema (S; n = 7), and cardiac pulmonary edema (C; n = 18). This clinical separation was confirmed by retrospective analysis of associated measures of hemodynamic and respiratory dysfunction. We found that both analog scintigrams (positive/negative for diffuse pulmonary PMN-In sequestration) and computer-assisted quantitative analysis in 46 patients (T 1/2 of first hour demargination and percentage of peak activity/pixel/second remaining at 17 to 20 h) showed a significant rank order decrease in the pulmonary retention of labeled PMN-In through the Groups Aa----As----S----Ar----C. Our findings recognized aspects of in vivo PMN-In behavior that implied pathophysiologic differences between groups of critically ill patients in either the PMN themselves or in PMN-pulmonary endothelial interaction. This demonstrates the possibility of abnormal in vivo PMN-endothelial interaction in ARDS by virtue of the greater pulmonary localization of PMN in active ARDS versus resolving disease, septic non-ARDS states, and cardiac pulmonary edema

    Studies have shown a relationship between energy metabolism and methylphenidate (MPH); however, there are no studies evaluating the effects of MPH in Krebs cycle. So, we investigated if MPH treatment could alter the activity of citrate synthase (CS), malate dehydrogenase (MD), and isocitrate dehydrogenase (ID) in the brain of young and adult Wistar rats. Our results showed that MPH (2 and 10 mg/kg) reduced CS in the striatum and prefrontal cortex (PF), with MPH at all doses in the cerebellum and hippocampus after chronic treatment in young rats. In adult rats the CS was reduced in the cerebellum after acute treatment with MPH at all doses, and after chronic treatment in the PF and cerebellum with MPH (10 mg/kg), and in the hippocampus with MPH (2 and 10 mg/kg). The ID decreased in the hippocampus and striatum with MPH (2 and 10 mg/kg), and in the cortex (10 mg/kg) after acute treatment in young rats. In adult rats acute treatment with MPH (2 and 10 mg/kg) reduced ID in the cerebellum, and with MPH (10 mg/kg) in the cortex; chronic treatment with MPH (10 mg/kg) decreased ID in the PF; with MPH (2 and 10 mg/kg) in the cerebellum, and with MPH at all doses in the hippocampus. The MD did not alter. In conclusion, our results suggest that MPH can alter enzymes of Krebs cycle in brain areas involved with circuits related with attention deficit hyperactivity disorder; however, such effects depend on age of animal and treatment regime.

    , particularly in the adult brain, remain poorly defined. Here we show that the absence of Dicer in the adult forebrain is accompanied by a mixed neurodegenerative phenotype. Although neuronal loss is observed in the hippocampus, cellular shrinkage is predominant in the cortex. Interestingly, neuronal...... degeneration coincides with the hyperphosphorylation of endogenous tau at several epitopes previously associated with neurofibrillary pathology. Transcriptome analysis of enzymes involved in tau phosphorylation identified ERK1 as one of the candidate kinases responsible for this event in vivo. We further...

    To investigate abnormalities in the skeleton (with the exclusion of the skull, cervical spine, hands and feet) in patients with Laron syndrome, who have an inborn growth hormone resistance and congenital insulin-like growth factor-1 (IGF-1) deficiency. The study group was composed of 15 untreated patients with Laron syndrome (seven male and eight female) aged 21-68 years. Plain films of the axial and appendicular skeleton were evaluated retrospectively for abnormalities in structure and shape. The cortical width of the long bones was evaluated qualitatively and quantitatively (in the upper humerus and mid-femur), and the cortical index was calculated and compared with published references. Measurements were taken of the mid-anteroposterior and cranio-caudal diameters of the vertebral body and spinous process at L3, the interpedicular distance at L1 and L5, and the sacral slope. Thoracic and lumbar osteophytes were graded on a 5-point scale. Values were compared with a control group of 20 healthy persons matched for age. The skeleton appeared small in all patients. No signs of osteopenia were visible. The cortex of the long bones appeared thick in the upper limbs in 11 patients and in the lower limbs in four. Compared with the reference values, the cortical width was thicker than average in the humerus and thinner in the femur. The vertebral diameters at L3 and the interpedicular distances at L1 and L5 were significantly smaller in the patients than in the control subjects (P < 0.001); however, at L5 the canal was wider, relative to the vertebral body. The study group had a higher rate of anterior osteophytes in the lumbar spine than the controls had, and their osteophytes were also significantly larger. In the six patients for whom radiographs of the upper extremity in its entirety were available on one film, the ulna appeared to be rotated. In one 22-year-old man, multiple epiphyses were still open. Congenital IGF-1 deficiency leads to skeletal abnormalities

    To obtain better insight into the biology of acute myeloid leukemia (AML) in various age groups, this study focused on the genetic changes occurring during a lifetime. This study analyzed the relation between age and genetics from birth to 100 years in 5564 patients with de novo AML diagnosed from 1998 to 2012 (1192 patients from nationwide pediatric studies [AML Berlin-Frankfurt-Münster studies 98 and 2004] and 4372 adults registered with the Munich Leukemia Laboratory). The frequencies of cytogenetic subgroups were age-dependent. Favorable subtypes (t(8;21), inv(16)/t(16;16), and t(15;17)) decreased in general from the pediatric age group (2 to groups ( 70 years; P age-specific incidence with age. Interestingly, the frequency of 11q23 abnormalities decreased from infants to older patients. The proportion of clinically relevant molecular aberrations of CCAAT/enhancer binding protein α, nucleophosmin (NPM1), and NPM1/fms-related tyrosine kinase 3-internal tandem duplication increased with age. Altogether, with the exclusion of infants, a significant decrease in the proportion of favorable cytogenetic subtypes and an increase in unfavorable cytogenetics were observed with increasing age. These findings indicate different mechanisms for the pathogenesis of AML; these different mechanisms also suggest directions for etiological research and contribute to the more unfavorable prognosis with increasing age.

    Full Text Available Background. Information regarding the progression of acute hepatitis B virus (HBV infection to chronic infection in adults is scarce. Methods. Twenty-five adult patients with acute HBV infection (14 men and 11 women, 18–84 years old, whose clinical features progressed to those of chronic infection (group A or did not (group B, were studied retrospectively. Results. There were 3 and 22 patients in groups A and B, respectively. Two of the 3 patients of group A lacked the typical symptoms of acute hepatitis. No differences were found between groups with respect to age, sex, or HBV genotypes. However, total bilirubin and alanine aminotransaminase levels were significantly lower in group A. Conclusions. Three of the 25 adult patients with acute HBV infection progressed to chronic infection. Hepatitis was mild in these patients. Patients with mild acute hepatitis B or unapparent HBV infection may have a higher risk of progressing to chronic infection.

    Restrictive lung defects are associated with higher mortality in patients with acquired chronic heart failure. We investigated the prevalence of abnormal lung function, its relation to severity of underlying cardiac defect, its surgical history, and its impact on outcome across the spectrum of adult congenital heart disease. A total of 1188 patients with adult congenital heart disease (age, 33.1±13.1 years) undergoing lung function testing between 2000 and 2009 were included. Patients were classified according to the severity of lung dysfunction based on predicted values of forced vital capacity. Lung function was normal in 53% of patients with adult congenital heart disease, mildly impaired in 17%, and moderately to severely impaired in the remainder (30%). Moderate to severe impairment of lung function related to complexity of underlying cardiac defect, enlarged cardiothoracic ratio, previous thoracotomy/ies, body mass index, scoliosis, and diaphragm palsy. Over a median follow-up period of 6.7 years, 106 patients died. Moderate to severe impairment of lung function was an independent predictor of survival in this cohort. Patients with reduced force vital capacity of at least moderate severity had a 1.6-fold increased risk of death compared with patients with normal lung function (P=0.04). A reduced forced vital capacity is prevalent in patients with adult congenital heart disease; its severity relates to the complexity of the underlying heart defect, surgical history, and scoliosis. Moderate to severe impairment of lung function is an independent predictor of mortality in contemporary patients with adult congenital heart disease.

    Acute hypoxaemia de novo or on a background of chronic hypoxaemia is a common reason for admission to intensive care and for provision of mechanical ventilation. Various refinements of mechanical ventilation or adjuncts are employed to improve patient outcomes. Mortality from acute respiratory distress syndrome, one of the main contributors to the need for mechanical ventilation for hypoxaemia, remains approximately 40%. Ventilation in the prone position may improve lung mechanics and gas exchange and could improve outcomes. The objectives of this review are (1) to ascertain whether prone ventilation offers a mortality advantage when compared with traditional supine or semi recumbent ventilation in patients with severe acute respiratory failure requiring conventional invasive artificial ventilation, and (2) to supplement previous systematic reviews on prone ventilation for hypoxaemic respiratory failure in an adult population. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 1), Ovid MEDLINE (1950 to 31 January 2014), EMBASE (1980 to 31 January 2014), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 31 January 2014) and Latin American Caribbean Health Sciences Literature (LILACS) (1992 to 31 January 2014) in Ovid MEDLINE for eligible randomized controlled trials. We also searched for studies by handsearching reference lists of relevant articles, by contacting colleagues and by handsearching published proceedings of relevant journals. We applied no language constraints, and we reran the searches in CENTRAL, MEDLINE, EMBASE, CINAHL and LILACS in June 2015. We added five new studies of potential interest to the list of "Studies awaiting classification" and will incorporate them into formal review findings during the review update. We included randomized controlled trials (RCTs) that examined the effects of prone position versus supine/semi recumbent position during conventional mechanical ventilation in

    An acute ankle sprain is a sudden-onset injury of one or more of the ankle ligaments. It is one of the most common musculoskeletal injuries in the general population as well as in athletes. In some countries, such as China and Korea, acupuncture is frequently used in the treatment of ankle sprains, either as a single treatment or a secondary intervention accompanied by standard medical treatment. To assess the effects (benefits and harms) of acupuncture for the treatment of ankle sprains in adults. We searched the Cochrane Bone, Joint and Muscle Trauma Group Specialised Register (May 2013), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2013, Issue 4), MEDLINE (1948 to May week 2 2013), EMBASE (1980 to May week 2 2013), China National Knowledge Infrastructure databases (1994 to August week 4 2013), the Cumulative Index to Nursing and Allied Health Literature (1937 to May 2013), the Allied and Complementary Medicine Database (1985 to May 2013), Science Links Japan (1996 to August week 4 2013), several Korean medical databases (August week 4 2013), the World Health Organization International Clinical Trials Registry Platform (August week 4 2013), the bibliographic references of included trials and conference proceedings. We included randomised and quasi-randomised controlled trials involving adults with acute ankle sprains. We included all types of acupuncture practices, such as needle acupuncture, electroacupuncture, laser acupuncture, pharmacoacupuncture, non-penetrating acupuncture point stimulation (e.g. acupressure and magnets) and moxibustion. Acupuncture could be compared with control (no treatment or placebo) or another standard non-surgical intervention. Two review authors independently screened the search results, assessed trial eligibility, assessed risk of bias and extracted data from the included trials. We calculated risk ratios (RRs) for dichotomous outcomes and mean differences for continuous outcomes. We conducted meta

  16. A BDNF loop-domain mimetic acutely reverses spontaneous apneas and respiratory abnormalities during behavioral arousal in a mouse model of Rett syndrome

    Directory of Open Access Journals (Sweden)

    Miriam Kron

    2014-09-01

    Full Text Available Reduced levels of brain-derived neurotrophic factor (BDNF are thought to contribute to the pathophysiology of Rett syndrome (RTT, a severe neurodevelopmental disorder caused by loss-of-function mutations in the gene encoding methyl-CpG-binding protein 2 (MeCP2. In Mecp2 mutant mice, BDNF deficits have been associated with breathing abnormalities, a core feature of RTT, as well as with synaptic hyperexcitability within the brainstem respiratory network. Application of BDNF can reverse hyperexcitability in acute brainstem slices from Mecp2-null mice, suggesting that therapies targeting BDNF or its receptor, TrkB, could be effective at acute reversal of respiratory abnormalities in RTT. Therefore, we examined the ability of LM22A-4, a small-molecule BDNF loop-domain mimetic and TrkB partial agonist, to modulate synaptic excitability within respiratory cell groups in the brainstem nucleus tractus solitarius (nTS and to acutely reverse abnormalities in breathing at rest and during behavioral arousal in Mecp2 mutants. Patch-clamp recordings in Mecp2-null brainstem slices demonstrated that LM22A-4 decreases excitability at primary afferent synapses in the nTS by reducing the amplitude of evoked excitatory postsynaptic currents and the frequency of spontaneous and miniature excitatory postsynaptic currents. In vivo, acute treatment of Mecp2-null and -heterozygous mutants with LM22A-4 completely eliminated spontaneous apneas in resting animals, without sedation. Moreover, we demonstrate that respiratory dysregulation during behavioral arousal, a feature of human RTT, is also reversed in Mecp2 mutants by acute treatment with LM22A-4. Together, these data support the hypothesis that reduced BDNF signaling and respiratory dysfunction in RTT are linked, and establish the proof-of-concept that treatment with a small-molecule structural mimetic of a BDNF loop domain and a TrkB partial agonist can acutely reverse abnormal breathing at rest and in response to

    Adult-onset calorie restriction (A-CR) is an experimental model of life extension and healthy aging less explored, compared with calorie restriction begun at early ages, but one more realistic for human application. We examined the effect of A-CR on the aging rat kidney with respect to common structural age-dependent changes and the accumulation of mitochondrial enzyme abnormalities in tubular epithelial cells. A 40% calorie restriction was initiated in middle-aged rats, before the onset of significant age-related changes in the Fischer x Brown Norway rat kidney. This dietary intervention effectively reduced glomerulosclerosis and tubular atrophy within 6 mo and changed the rate of interstitial fibrosis formation within 1 yr and vascular wall thickening and the expression cytochrome c oxidase (COX)-deficient tubular epithelial cells in 18 mo compared with age-matched ad libitum-fed rats. Our histological approach (histochemical staining for mitochondrial enzyme activity and laser capture microdissection) coupled with mitochondrial DNA (mtDNA) PCR analyses demonstrated that COX-deficient renal tubular epithelial cells accumulated mtDNA deletion mutations and that these cells contained unique, clonally expanded mtDNA deletion mutations. Renal tubular epithelial cells with mitochondrial abnormalities presented cellular characteristics indicative of physiological dysfunction.

    Uniparental disomy (UPD) of a number of different chromosomes has been found in association with abnormal phenotypes. A growing body of evidence for an imprinting effect involving chromosome 14 has been accumulating. We report on a case of paternal UPD of chromosome 14 studied in late gestation due to polyhydramnios and a ventral wall hernia. A prenatal karyotype documented a balanced Robertsonian 14:14 translocation. The baby was born prematurely with hairy forehead, retrognathia, mild puckering of the lips and finger contractures. Hypotonia has persisted since birth and at age one year, a tracheostomy for laryngomalacia and gastrostomy for feeding remain necessary. Absence of maternal VNTR polymorphisms and homozygosity of paternal polymorphisms using chromosome 14 specific probes at D14S22 and D14S13 loci indicated paternal uniparental isodisomy (pUPID). Parental chromosomes were normal. We also report on a case of maternal LTPD in a normal patient with a balanced Robertsonian 14:14 translocation and a history of multiple miscarriages. Five previous reports of chromosome 14 UPD suggest that an adverse developmental effect may be more severe whenever the UPD is paternal in origin. This is the second reported patient with paternal UPD and the fifth reported with maternal UPD, and only few phenotypic similarities are apparent. Examination of these chromosome 14 UPD cases of maternal and paternal origin suggests that there are syndromic imprinting effects. 30 refs., 3 figs.

    This study was undertaken to investigate the role of gold nanoparticles (GNPs) of 50 nm diameter on isoproterenol (ISO) induced acute myocardial infarction in adult male albino rats. Forty five adult Wistar male albino rats were equally divided into three groups. Control (group I) was further subdivided into three subgroups. In group II, the rats received ISO subcutaneously at a dose of 100 mg/kg for three days. In group III, rats received ISO as group II and then GNPs (400 μg/kg/day) intravenously for 14 consecutive days. Echocardiography was performed. Left ventricular specimens were prepared for H&E, van Gieson staining, immunohistochemical analysis for (eNOs and Bcl-2), and Electron microscope examination. Energy dispersive X-ray microanalysis was also performed. Cardiac markers such as creatine Kinase-MB (CK-MB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), and cardiac troponin T (cTnT) were measured. Group II revealed cardiomyocytes with deeply stained acidophilic cytoplasm, small dark nuclei, intracellular vacuolations, wide intercellular spaces, and extravasated red blood cells. Increased collagen fibers were observed. Electron microscope examination showed cardiomyocyte with small and irregular outlined nuclei, mitochondria with irregular cristae and others with ruptured mitochondrial membrane, abnormal alignment of myofibrils, dilated cisternae of smooth endoplasmic reticulum, and disorganized intercalated discs. Group III showed that most cardiomyocytes preserved the normal architecture. Increased expression of eNOs immunoreaction and decreased Bcl-2 immunoreaction were detected in group II as compared to the control and GNP-treated groups. These findings suggested that GNPs of 50 nm diameter improved myocardial injury after ISO-induced myocardial infarction in rats.

    To examine whether older people with abnormal thyroid function are more likely to develop chronic kidney disease (CKD) over a 5-year follow-up period. Retrospective cohort study. Health examination data from the Taipei Databank for Public Health Analysis. Individuals aged 65 and older (N = 41,454). Thyroid-stimulating hormone (TSH) levels were repeatedly measured, and subjects were categorized into four thyroid function groups (hyperthyroid, euthyroid, subclinical hypothyroid, overt hypothyroid). The risk of incident CKD was evaluated using a stepwise Cox proportional hazards regression model adjusted for sex, baseline age, hypertension, diabetes mellitus (DM), dyslipidemia, hyperuricemia, anemia, obesity, liver function, smoking, and alcohol. Higher TSH levels were associated with greater risk of subsequent CKD. Individuals with subclinical hypothyroidism (hazard ratio (HR) = 1.15, 95% confidence interval (CI) = 1.05-1.26) and those with overt hypothyroidism (HR = 1.27, 95% CI = 1.04-1.55) were more likely than those who were euthyroid to have CKD. Women were more likely to have CKD than men (HR = 1.11, 95% CI = 1.06-1.16). When stratified by gender, subclinical hypothyroidism in women was associated with an increased risk of developing CKD (HR = 1.22; 95% CI = 1.08-1.39). When stratified by DM, subclinical hypothyroidism and overt hypothyroidism were associated with an increased risk of developing CKD in nondiabetics (HR = 1.19; 95% CI = 1.07-1.31; and HR = 1.34; 95% CI = 1.08-1.65, respectively). This cohort study of elderly persons in Taipei City found a significant association between hypothyroidism and development of CKD in women and individuals without DM. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    This study examined the relation between childhood ocular alignment deficits and adult psychiatric outcomes among children at high-risk for schizophrenia and controls. A sample of 265 Danish children was administered a standardized eye exam assessing strabismus and related ocular alignment deficits....... All children whose mothers or fathers had a psychiatric diagnosis of schizophrenia comprised the first group (N=90). Children who had at least one parent with a diagnosis other than schizophrenia comprised the first matched control group (N=93). The second control group consisted of children...... offspring of parents with other non-psychotic disorder and no mental illness), although the results failed to reach statistical significance. Results from this study suggest a premorbid relation between ocular deficits and schizophrenia-spectrum disorders in childhood prior to onset of psychopathology...

    Bisphenol-A (BPA) is one of the most widespread endocrine disrupting chemicals (EDC) used as the base compound in the manufacture of polycarbonate plastics. Although evidence points to consider exposure to BPA as a risk factor for insulin resistance, its actions on whole body metabolism and on insulin-sensitive tissues are still unclear. The aim of the present work was to study the effects of low doses of BPA in insulin-sensitive peripheral tissues and whole body metabolism in adult mice. Adult mice were treated with subcutaneous injection of 100 µg/kg BPA or vehicle for 8 days. Whole body energy homeostasis was assessed with in vivo indirect calorimetry. Insulin signaling assays were conducted by western blot analysis. Mice treated with BPA were insulin resistant and had increased glucose-stimulated insulin release. BPA-treated mice had decreased food intake, lower body temperature and locomotor activity compared to control. In skeletal muscle, insulin-stimulated tyrosine phosphorylation of the insulin receptor β subunit was impaired in BPA-treated mice. This impairment was associated with a reduced insulin-stimulated Akt phosphorylation in the Thr308 residue. Both skeletal muscle and liver displayed an upregulation of IRS-1 protein by BPA. The mitogen-activated protein kinase (MAPK) signaling pathway was also impaired in the skeletal muscle from BPA-treated mice. In the liver, BPA effects were of lesser intensity with decreased insulin-stimulated tyrosine phosphorylation of the insulin receptor β subunit. In conclusion, short-term treatment with low doses of BPA slows down whole body energy metabolism and disrupts insulin signaling in peripheral tissues. Thus, our findings support the notion that BPA can be considered a risk factor for the development of type 2 diabetes. PMID:22470480

    Full Text Available Background: Arsenic toxicity is a major global health problem and exposure via contaminated drinking water has been associated with hematological and other systemic disorders. The present investigation has been conducted in adult male rats to evaluate the protective ability of α-lipoic acid (ALA against such hematological disorders. Methods: Twenty-four adult male Wister rats (b.wt.130±10g were grouped and accordingly group I (control received the normal diet, group II (treated was given arsenic orally for 28 consecutive days as arsenic trioxide (3 mg/kgbw/rat/day whereas group III (supplemented received the same dose of arsenic along with ALA (25 mg/kgbw/rat/day as oral supplement. Hematological profile, plasma oxidant/antioxidant status, and erythrocyte morphology were assessed. Statistical analysis was done by one-way ANOVA using SPSS software (version 16.0. Results: Arsenic exposure caused reduction of erythrocyte (P=0.021, leucocyte (P<0.001, and hemoglobin (P=0.031 associated with echinocytic transformation as evidenced by light and scanning electron microscopic studies. The other significantly altered parameters include increased mean corpuscular volume (P=0.041 and lymphocytopenia (P<0.001 with insignificant neutropenia and eosinophilia. Altered serum oxidative balance as evidenced by decreased TAS (P<0.001 and increased TOS (P<0.001 with OSI (P<0.001 was also noted. The dietary supplementation of ALA has a beneficial effect against the observed (P<0.05 arsenic toxicities. It brings about the protection by restoring the hematological redox and inflammatory status near normal in treated rats. Arsenic-induced morphological alteration of erythrocytes was also partially attenuated by ALA supplementation. Conclusion: It is concluded that arsenicosis is associated with hematological alterations and ALA co-supplementation can partially alleviate these changes in an experimental male rat model.

  10. Acute Exercise and Neurocognitive Development in Preadolescents and Young Adults: An ERP Study

    Full Text Available The purpose of this study was to examine the effect of a single bout of exercise on neurocognitive function in preadolescent children and young adults by determining the modulatory role of age and the neuroelectrical mechanism(s underlying the association between acute exercise and executive function. Twenty preadolescents and 20 young adults completed the Stroop test, and neuroelectrical activity was recorded during two treatment sessions performed in a counterbalanced order. Exercise treatments involved moderate intensity aerobic exercise for 20 min as the main exercise and two 5 min periods of warm-up and cool-down. The control treatment participants read for a similar duration of time. Acute exercise improved participant reaction times on the Stroop test, regardless of Stroop congruency, and greater beneficial effects were observed in young adults compared to those in preadolescents. The P3 amplitudes increased after acute exercise in preadolescents and young adults, but acute exercise induced lower conflict sustained potential (conflict SP amplitudes in preadolescent children. Based on these findings, age influences the beneficial effect of acute exercise on cognitive performance in general. Furthermore, the event-related brain potential differences attributed to acute exercise provide a potential clue to the mechanisms that differentiate the effects of acute exercise on individuals from preadolescence to young adulthood.

    Household air pollution from solid fuel burning kills over 4 million people every year including half a million children from acute lower respiratory infections. Although biologically plausible, it is not clear whether household air pollution is also associated with acute lower respiratory infections in adults. We systematically reviewed the literature on household air pollution and acute lower respiratory infection in adults to identify knowledge gaps and research opportunities. Ten bibliographic databases were searched to identify studies of household air pollution and adult acute lower respiratory infection. Data were extracted from eligible studies using standardised forms. From 4617 titles, 513 abstracts and 72 full-text articles were reviewed. Eight studies met the inclusion criteria of which 2 found a significant adjusted increased risk of acute lower respiratory infection, 2 identified a univariate association whilst 4 found no significant association. Study quality was generally limited. Heterogeneity in methods and findings precluded meta-analysis. A systematic review of the literature found limited evidence for an association between household air pollution and risk of acute lower respiratory infection in adults. Additional research, with carefully defined exposure and outcome measures, is required to complete the risk profile caused by household air pollution in adults. CRD42015028042.

    Persistently abnormal /sup 99m/Tc stannous pyrophosphate myocardial scintigrams (PPi+) appear to be associated with a relatively poor prognosis after acute myocardial infarction (AMI). To assess the incidence and implications of PPi+, we performed a retrospective analysis in 29 patients with and 25 patients without diabetes mellitus who had abnormal myocardial scintigrams within 4 days of AMI and who had follow-up scintigrams at least 3 months after hospital discharge. There were no significant differences between patients with and without diabetes as regards age, incidence of transmural or nontransmural AMI, or degree of left ventricular dysfunction after AMI. Persistently abnormal PPi+ occurred more commonly in patients with diabetes than in nondiabetic patients (18 of 29, 62%, compared to 3 of 25, 12%; p less than 0.001). Patients with chronic PPi+ had more frequent cardiac complications following hospital discharge (p less than 0.005) including death, recurrent AMI, unstable angina, and intractable congestive heart failure. Postmortem analysis in two patients with diabetes and chronic PPi+ revealed marked myocytolysis. Thus, patients with diabetes mellitus have an increased incidence of post-AMI persistently abnormal technetium (PPi+) scintigrams and relatively poor prognosis following myocardial infarction

  15. Magnetization transfer imaging identifies basal ganglia abnormalities in adult ADHD that are invisible to conventional T1 weighted voxel-based morphometry

    Full Text Available In childhood, Attention Deficit Hyperactivity Disorder (ADHD is reliably associated with reduced volume of the striatum. In contrast, striatal abnormalities are infrequently detected in voxel-based morphometry (VBM neuroimaging studies of adults with ADHD. This discrepancy has been suggested to reflect normalisation of striatal morphology with age and prolonged treatment of symptoms. If so, this would indicate that while striatal abnormalities are linked to symptom expression in childhood, they cannot explain the persistence of these symptoms in adulthood. However, this may not be case. Instead, we hypothesized that the lack of evidence for striatal abnormalities in adult ADHD may reflect poor sensitivity of typical (T1-weighted neuroimaging to detect subcortical differences. To address this, we acquired both magnetisation transfer (MT saturation maps optimised for subcortical contrast, and conventional T1-weighted images in 30 adults with ADHD and 30 age, IQ, gender and handedness-matched controls. Using VBM of both datasets, we demonstrate volumetric reductions within the left ventral striatum on MT that are not observed on identically pre-processed T1-weighted images from the same participants. Nevertheless, both techniques reported similar sensitivity to cortical abnormalities in the right inferior parietal lobe. Additionally, we show that differences in striatal iron may potentially explain this reduced sensitivity of T1-weighted images in adults. Together, these findings indicate that prior VBM studies reporting no abnormalities in striatal volume in adult ADHD might have been compromised by the methodological insensitivity of T1-weighted VBM to subcortical differences, and that structural abnormalities of the striatum in ADHD do indeed persist into adulthood.

    Marijuana is the most commonly used illicit drug in the United States, but little is known about its effects on the human brain, particularly on reward/aversion regions implicated in addiction, such as the nucleus accumbens and amygdala. Animal studies show structural changes in brain regions such as the nucleus accumbens after exposure to Δ9-tetrahydrocannabinol, but less is known about cannabis use and brain morphometry in these regions in humans. We collected high-resolution MRI scans on young adult recreational marijuana users and nonusing controls and conducted three independent analyses of morphometry in these structures: (1) gray matter density using voxel-based morphometry, (2) volume (total brain and regional volumes), and (3) shape (surface morphometry). Gray matter density analyses revealed greater gray matter density in marijuana users than in control participants in the left nucleus accumbens extending to subcallosal cortex, hypothalamus, sublenticular extended amygdala, and left amygdala, even after controlling for age, sex, alcohol use, and cigarette smoking. Trend-level effects were observed for a volume increase in the left nucleus accumbens only. Significant shape differences were detected in the left nucleus accumbens and right amygdala. The left nucleus accumbens showed salient exposure-dependent alterations across all three measures and an altered multimodal relationship across measures in the marijuana group. These data suggest that marijuana exposure, even in young recreational users, is associated with exposure-dependent alterations of the neural matrix of core reward structures and is consistent with animal studies of changes in dendritic arborization.

    Cytogenetic abnormalities and early response to treatment are the main prognostic factors in acute myeloid leukemia (AML). Recently, NUP98/NSD1 (t(5; 11)(q35; p15)), a cytogenetically cryptic fusion, was described as recurrent event in AML, characterized by dismal prognosis and HOXA/B gene overexpression. Using split-signal fluorescence in situ hybridization, other NUP98-rearranged pediatric AML cases were identified, including several acute megakaryoblastic leukemia (AMKL) cases with a cytogenetically cryptic fusion of NUP98 to JARID1A (t(11;15)(p15;q35)). In this study we screened 105 pediatric AMKL cases to analyze the frequency of NUP98/JARID1A and other recurrent genetic abnormalities. NUP98/JARID1A was identified in 11/105 patients (10.5%). Other abnormalities consisted of RBM15/MKL1 (n=16), CBFA2T3/GLIS2 (n=13) and MLL-rearrangements (n=13). Comparing NUP98/JARID1A-positive patients with other pediatric AMKL patients, no significant differences in sex, age and white blood cell count were found. NUP98/JARID1A was not an independent prognostic factor for 5-year overall (probability of overall survival (pOS)) or event-free survival (probability of event-free survival (pEFS)), although the 5-year pOS for the entire AMKL cohort was poor (42 ± 6%). Cases with RBM15/MLK1 fared significantly better in terms of pOS and pEFS, although this was not independent from other risk factors in multivariate analysis. NUP98/JARID1A cases were characterized by HOXA/B gene overexpression, which is a potential druggable pathway. In conclusion, NUP98/JARID1A is a novel recurrent genetic abnormality in pediatric AMKL.

    To assess the geographic distribution of acute complications in patients with type 1 diabetes in a large urban centre; and to assess the association between acute complications and community-level sociodemographic factors. Adults (aged ≥18 years old) with type 1 diabetes and acute complications were identified between 2004 and 2008 by using a diabetes centre clinical database or discharge abstracts for acute complications (diabetic ketoacidosis or hypoglycemia). Using a geographic information system, hot-spot analysis was used to identify spatial clusters of acute complications in a large urban centre. The association between acute complications and community-level sociodemographic factors were assessed by Spearman rank correlation. We identified 1779 patients with type 1 diabetes, of whom 456 had been hospitalized for acute complications. The mean age of patients was 40.9±16.0 years, and men were more likely to have acute complications (59.2% vs. 52.3%; p<0.01). Spatial clusters of high values and low values were identified. Higher median family income (r=-0.36; p<0.0001) and higher education levels (r=-0.30; p<0.0001) were associated with lower rates of acute complications. This study demonstrated geographic clusters of hospitalizations for acute complications and important community sociodemographic factors. Prevention strategies and interventions targeting these geographic and sociodemographic disparities need to be explored as a means of minimizing hospitalizations for acute complications.

    Studies on adolescents and young adults with acute lymphoblastic leukemia suggest better results when using pediatric protocols for adult patients, while corresponding data for acute myeloid leukemia (AML) are limited. We investigated disease characteristics and outcome for de novo AML patients 10-30 years old treated in pediatric or adult departments. We included 166 patients 10-18 years of age with AML treated according to the pediatric NOPHO-protocols (1993-2009) compared with 253 patients aged 15-30 years treated in hematology departments (1996-2009) in the Nordic countries. The incidence of AML was 4.9/million/year for the age group 10-14 years, 6.5 for 15-18 years, and 6.9 for 19-30 years. Acute promyelocytic leukemia (APL) was more frequent in adults and in females of all ages. Pediatric patients with APL had similar overall survival as pediatric patients without APL. Overall survival at 5 years was 60% (52-68%) for pediatric patients compared to 65% (58-70%) for adult patients. Cytogenetics and presenting white blood cell count were the only independent prognostic factors for overall survival. Age was not an independent prognostic factor. No difference was found in outcome for AML patients age 10-30 years treated according to pediatric as compared to adult protocols. © 2015 Wiley Periodicals, Inc.

    Major depressive disorder (MDD) is a common mental disorder with high morbidity. As a part of the limbic system, the amygdala is important in the processing of emotional information. Structural and functional connectivity (FC) abnormalities in the amygdala have been observed in MDD patients. The present study was carried out to identify the features of amygdala FC in adult MDD patients with different ages of onset. Sixty-nine first-episode and untreated MDD patients and 81 healthy controls (CTLs) were included in this study and underwent 3D structural imaging and resting-state functional MRI scanning. The patients and CTLs were divided into two groups according to age of onset: young adult (amygdala seeds to the whole brain of MDD patients and matched CTLs in these two different onset age groups were analysed. We found that the volume of the bilateral amygdala increased to a greater extent in young adult patients compared with old adult patients. We also observed a trend toward different amygdala FC by onset age in MDD patients. In young adult patients, the left amygdala showed more abnormal resting-state FC with other regions compared with matched controls. However, in old adult patients, compared with matched controls, the right amygdala showed more abnormal changes in the resting-state FC with other regions. MDD patients with different ages of onset showed different changes in the structure and FC of the amygdala. These results might help us to understand the high heterogeneity of MDD.

    To study the signal patterns of dual color dual fusion fluorescence in situ hybridization (DCDF-FISH) for detection of genetic abnormality in adult acute lymphoblastic leukemia (ALL) patients and their diagnostic value and clinical application. The clinical data of 68 ALL patients confirmed in our hospital were analyzed retrospectively; The bone marrow samples were detected by DCDF-FISH, flow cytometry, conventional cytogenetics (CCG), reverse transcriptase polymerase chain reaction (RT-PCR), and the correlation of these results was compared. And the reaction of patients to treatment was dynamically observed by DCDF-FISH. Sixteen signal patterns were found in DCDF-FISH, including 14 kinds of atypical signal patterns (signal patterns of 1R2G, 2R3G, 2R4G and 3R3G as abnormal signal patterns without BCR/ABL fusion gene. Signal patterns of 1R1G1F, 1R1G3F, 1R1G4F, 1R2G1F, 1R2G2F, 1R2G3F, 1RnG2F (n ≥ 3), 2R2G1F, 1G4F, 1R4F corresponded to t (9;22) karyotype). Ph(+) ALL patients accounted for 17. All cases with Ph chromosome or BCR/ABL positive were B-ALL or My(+)-B-ALL. The Ph chromosome was detected in 12 cases (positive rate was 18%) by CCG. The positive rate was 25% (17/68) by DCDF-FISH and RT-PCR. The DCDF-FISH fluorescence pattern change before and after chemotherapy of the patients showed that the quantity and form of the signal pattern was changed after chemotherapy, and the common characteristics was the Ph chromosome in patients. The DCDF-FISH is a sensitive and reliable method for the detection of BCR/ABL rearrangement. Analyzing the dynamical change of DCDF-FISH signal patterns has been comfirmed to have a important guiding significance in the diagnosis, and anlysis of response to therapy, drug resistance and the prognosis of ALL patients.

    Duodenal duplication cysts are rare congenital abnormalities which are more commonly diagnosed in infancy and childhood. However, in rare cases, these lesions can remain asymptomatic until adulthood. The combination of duplication cyst and pancreas divisum is extremely rare and both conditions have been linked with acute recurrent pancreatitis. We present the case of a 37 years-old patient who presented with repeated episodes of acute pancreatitis. By means of magnetic resonance imaging and endoscopic ultrasonography we discovered a duplication cyst whose cavity received drainage from the dorsal pancreas. After opening the cyst cavity to the duodenal lumen with a needle knife the patient presented no further episodes in the clinical follow-up. Comparable literature findings and therapeutic options for these abnormalities are discussed with regard to the presented case. PMID:21160764

    Full Text Available The objectives of this review were to discuss standard and investigational treatment strategies for adolescent and young adult with acute myeloid leukemia, excluding acute promyelocytic leukemia. Acute myeloid leukemia (AML in adolescent and young adult patients (AYAs may need a different type of therapy than those currently used in children and older patients. As soon as AML is diagnosed, AYA patient should be offered to participate in well-designed clinical trials. The standard treatment approach for AYAs with AML is remission induction chemotherapy with an anthracycline/cytarabine combination, followed by either consolidation chemotherapy or stem cell transplantation, depending on the ability of the patient to tolerate intensive treatment and cytogenetic features. Presently, continuing progress of novel drugs targeting specific pathways in acute leukemia may bring AML treatment into a new era.

    Continuity of care (COC) for acutely unwell older adults, particularly those who are nursing home residents, who present to hospital, is complicated by the presence of co-morbid conditions, long waiting times, both for the ambulance and in the department, and poor after-hours general practitioner access. To present a critical review of the literature on COC for older adults from nursing homes who present to hospital and who are acutely unwell. The review will answer the following questions: (i) What is the contemporary meaning of the construct continuity of care? (ii) What is the relevance of continuity of care to the population of older adults who reside in nursing homes and present to hospital? and (iii) What models exist for promoting continuity of care to older adults who present to hospital? Guided by the conceptual analysis process a database search of CINAHL and MEDLINE was carried out utilizing the search terms 'continuity of care', 'older adults', 'nursing homes', 'emergency department' and 'acute illness'. A hand-search of additional references was also conducted. Retrieved articles were critically reviewed if they focused on older adult patients, the acute care/community settings and COC. The contemporary meaning of the COC is that it incorporates care of an individual patient over time by bridging discrete elements in the care pathway. Four distinct models of COC were identified. These were Primary Health Care; General Practice and Primary Medical Care; Consumers; and Health Policy and Systems. All are based on the proviso that the individual is sufficiently independent to be able to coordinate their own care and to take overall responsibility. The connection between COC and acutely unwell older adults who present to hospital is a prolific area for further research. In particular, the effectiveness of programmes aimed at enhancing the advanced nursing practice role and the COC process for older adults, needs investigation.

    Extracorporeal life support (ECLS) is an artificial means of maintaining adequate oxygenation and carbon dioxide elimination to enable injured lungs to recover from underlying disease. Technological advances have made ECLS devices smaller, less invasive, and easier to use. ECLS might, therefore, represent an important step towards improved management and outcomes of patients with acute respiratory distress syndrome. Nevertheless, rigorous evidence of the ability of ECLS to improve short-term and long-term outcomes is needed before it can be widely implemented. Moreover, how to select patients and the timing and indications for ECLS in severe acute respiratory distress syndrome remain unclear. We describe the physiological principles, the putative risks and benefits, and the clinical evidence supporting the use of ECLS in patients with acute respiratory distress syndrome. Additionally, we discuss controversies and future directions, such as novel technologies and indications, mechanical ventilation of the native lung during ECLS, and ethics considerations.

    Citrin deficiency is an autosomal recessive genetic disorder caused by a defect in the mitochondrial aspartate/glutamate antiporter, citrin. The disorder manifests either as neonatal intra-hepatic cholestasis or occurs in adulthood with recurrent hyperammonemia and neuropsychiatric disturbances. It has a high prevalence in the East Asian population, but is actually pan-ethnic. We report the case of a 26-year-old male patient presenting with episodes of abnormal neuro-psychiatric behavior asso...

    While the blood vessels are exposed to high pressures in hypertension, the main complications of hypertension (stroke and myocardial infarction) are paradoxically thrombotic rather than haemorrhagic. To investigate abnormalities of haemorheology (plasma viscosity, fibrinogen), endothelial dysfunction (von Willebrand factor), platelet activation (soluble P-selectin) and thrombogenesis (plasminogen activator inhibitor and fibrin D-dimer) in stroke and the effects of concurrent hypertension, we studied 86 consecutive patients (58 male, 28 female) aged ictus 160 mmHg and/or diastolic > 90 mmHg) on admission and those without hypertension. Mean plasma viscosity (one-way analysis of variance, P = 0.026) and fibrinogen levels (P = 0.016) were significantly higher in stroke patients and hospital controls, when compared with healthy controls. The von Willebrand factor, plasminogen activator inhibitor soluble P-selectin and fibrin D-dimer levels were highest in the acute stroke patients, intermediate in hospital controls and lowest in healthy controls (all P 160 mmHg or diastolic blood pressures > 90 mmHg using clinical (manual) readings or mean daytime or night-time ambulatory blood pressure monitoring recordings. There were no statistically significant differences between the measured parameters on admission and at 3 months follow-up in 26 patients (all P = not significant). Plasma viscosity was significantly correlated with mean daytime systolic blood pressure (r = 0.314, P = 0.021) and mean night-time systolic blood pressure (r = 0.309, P = 0.025). This study of hypertension and haemostasis in acute stroke has demonstrated clear abnormalities of haemorheology, endothelial dysfunction, platelet activation and thrombogenesis, which do not appear to be affected by the height of the blood pressure or the presence of hypertension. This is despite the known hypercoagulable state found in hypertension and the relationship of haemostatic abnormalities to vascular complications.

    While temporal and perceptual processing abnormalities, identified in a number of electrophysiological and brain imaging studies of individuals with (ASD), are likely to impact on speech perception, surprisingly little is known about the behavioral outcomes of such abnormalities. It has been hypothesized that rapid temporal processing deficits may be linked to impaired language development through interference with acoustic information during speech perception. The present study aimed to investigate the impact of temporal changes on encoding and recall of speech, and the associated cognitive, clinical, and behavioral correlates in adults with ASD. Research carried out with typically developing (TD) adults has shown that word recall diminishes as the speed of speech increases, and it was predicted that the magnitude of this effect would be far greater in those with ASD because of a preexisting rapid temporal processing deficit. Nineteen high-functioning adults with ASD, and age- and intelligence-matched TD controls performed verbatim recall of temporally manipulated sentences. Reduced levels of word recall in response to increases in presentation speed were observed, and this effect was greater in the older participants in the ASD group than in the control group. This is the first study to show that both sensory abnormalities and aging impact on speech encoding in ASD. Auditory processing deficits in ASD may be indicative of an association with the sensory abnormalities and social and communication impairments characterizing the disorder. © 2013 International Society for Autism Research, Wiley Periodicals, Inc.

    Adult seroprevalence of HAV is decreasing in developed countries including South Korea, due to general sanitation improvement. Although hepatitis A vaccination was introduced in South Korea more than 20 years ago, recent infection rates have not decreased. In this study, we investigate the seroprevalence of anti-HAV IgG, and estimate the national disease burden of acute hepatitis A in adult population. Seroprevalence data were collected from health promotion center of Korea University Guro Hospital, in Seoul, Korea from 2010 to 2014. Data from adults (≥20-years) being tested for anti-HAV IgG were included. In addition, epidemiological and clinical data of patients diagnosed with acute hepatitis A from 2009 to 2013, were collected from Korean Statistical Information Service (KOSIS) and the National Health Insurance Service (NHIS) database. Data were stratified and compared by age groups. A total of 11,177 subjects were tested for anti-HAV IgG from 2010 to 2014. Age-related seroprevalence showed relatively low seropositivity in young adults. Incidence of acute hepatitis A was highest in 2009 and lowest in 2013. When categorized by age group, adults in their 20s and 30s had more HAV infections and related-admissions than older adults. However, ICU admission rate and average insurance-covered cost was high in older adults. The anti-HAV IgG seropositivity in Korean younger adult population was low while the incidence of acute hepatitis A was high, especially in the 20-39 aged. However, a substantial number of older adults were infected, and required more intensive procedures and incurred higher insurance-covered medical costs.

    Chromosomal abnormalities play an important role in genesis of acute lymphoblastic leukemia (ALL) and have prognostic implications. Five major risk stratifying fusion genes in ALL are BCR-ABL, MLL-AF4, ETV6-RUNX11, E2A-PBX1 and SIL-TAL1. This work aimed to detect common chromosomal translocations and associated fusion oncogenes in adult ALL patients and study their relationship with clinical features and treatment outcome. We studied fusion oncogenes in 104 adult ALL patients using RT-PCR and interphase-FISH at diagnosis and their association with clinical characteristics and treatment outcome. Five most common fusion genes i.e. BCR-ABL (t 9; 22), TCF3-PBX1 (t 1; 19), ETV6-RUNX1 (t 12; 21), MLL-AF4 (t 4; 11) and SIL-TAL1 (Del 1p32) were found in 82/104 (79%) patients. TCF3-PBX1 fusion gene was associated with lymphadenopathy, SIL-TAL positive patients had frequent organomegaly and usually presented with a platelets count of less than 50 x10(9)/l. Survival of patients with fusion gene ETV6-RUNX1 was better when compared to patients harboring other genes. MLL-AF4 and BCR-ABL positivity characterized a subset of adult ALL patients with aggressive clinical behaviour and a poor outcome. This is the first study from Pakistan which investigated the frequency of 5 fusion oncogenes in adult ALL patients, and their association with clinical features, treatment response and outcome. Frequencies of some of the oncogenes were different from those reported elsewhere and they appear to be associated with distinct clinical characteristics and treatment outcome. This information will help in the prognostic stratification and risk adapted management of adult ALL patients.

    Infectious processes that can cause acute upper airway obstruction in adults include Ludwig's angina, retropharyngeal infection, acute epiglottis, diphtheria, tetanus, and peritonsillar abscess. They are uncommon but potentially lethal. Ludwig's angina in particular quickly progresses to airway obstruction. In most cases, the mainstays of management are antibiotics, surgical drainage, and if necessary, airway maintenance by tracheostomy, cricothyrotomy, or nasotracheal or endotracheal intubation. Hereditary angioneurotic edema causes episodes of laryngeal edema that may lead to suffocation. In an acute episode the airway must be maintained by endotracheal intubation.

  16. Metabolic abnormalities in adult HIV infected population on antiretroviral medication in Malaysia: a cross-sectional survey

    2013-01-01

    Background In the current two decades, dyslipidemia and increased blood glucose as metabolic abnormalities are the most common health threats with a high incidence among HIV/AIDS patients on antiretroviral (ARV) treatment. Scientific investigations and reports on lipid and glucose disorders among HIV infected communities are inadequate especially in those developing such as Malaysia. This cross-sectional survey was mainly aimed to evaluate the prevalence of metabolic abnormalities and associated risk factors among HIV infected population patients on ARV medication. Methods In a single reference health center in Malaysia, 2739 adult HIV positive patients on antiretroviral therapy (ART) were studied cross-sectionally using medical records. Besides demographic variables and associated health disorders, those factors which can change the lipid and glucose levels were collected. Logistic Regression was used to find the potential risk factors (p aged between 30–49 (68.6%). Mean CD4 count was 474.25 (cells/mm3) while undetectable RNA viral load was common among 83.3 (%) of subjects. Among 1,583 patients with the recent blood lipid and glucose tests, increased levels of triglyceride (TG) and total cholesterol (TC) were frequently prevalent in half of the population as 59 (%) and 54.2 (%) while 28.7 (%), 35.1 (%) and 38.2 (%) had declined level of high-density lipoprotein (HDL), raised low-density lipoprotein (LDL) and fasting plasma glucose (FPG) which were less common. Dyslipidemia was common in 82.3 (%) of the subjects. Notably, medication with protease inhibitor (PI) was a potential risk for elevated triglyceride (odds ratio (OR) = 2.309, 95% confidence interval (CI) = 1.605–3.324, P = 0.001), high TC (OR = 1.561, 95% CI = 1.123–2.169, P = 0.008) and low HDL (OR = 1.449, 95% CI = 1.037–2.024, P = 0.029). As lifestyle factor, alcohol consumption results as significant risk factor for raised TG (OR = 2.653, 95% CI = 1

    Introduction: Acute corrosive poisonings are caused by ingestion of corrosive chemicals which are most commonly used as household agents. Intoxications with these kind of agents produce numerous and severe post-corrosive complications of the upper gastrointestinal tract. On the other hand, our experience showed that corrosive agents may also cause injuries of the respiratory system, which makes the treatment very hard and additionally complicates the severe clinical condition of the patient. Objective: The aim of the study is to show the incidence of respiratory complications in acute corrosive poisonings, the need of various clinical investigations and also the treatment and final outcome of these kind of poisoning. Methods: We retrospectively analyzed clinical records of 415 patients hospitalized and treated at the University clinic for toxicology and urgent internal medicine, in Skopje, Republic of Macedonia, in the period between 2007 and 2011. The protocol consisted of methods for analyzing the systemic complications, with an accent on the post-corrosive respiratory complications. Results: From the total number of patients even 98 (23.61%) exhibited systemic complications, from which 51 (52.04%) are respiratory complications. The majority of patients are female (n=40, 78.43%) and the most common complication is pneumonia (n=47). The youngest patient in this study was 14 and the oldest was 87 years old. Conclusion: Besides the gastrointestinal complications in the acute corrosive poisonings respiratory complications are also very often. They complicate the clinical state of patient and very often lead to fatal endings. PMID:24944527

    Eight groups of male adolescent and adult spontaneous hyperactive rats (SHR) were used in a dose response (saline, 0.6, 2.5, and 10 mg/kg) experiment of methylphenidate (MPD). Four different locomotor indices were recorded for 2 hours postinjection using a computerized monitoring system. Acutely, the 0.6 mg/kg dose of MPD did not elicit an increase in locomotor activity in either the adolescent or in the adult male SHR. The 2.5 and the 10.0 mg/kg doses increased activity in the adolescent and the adult rats. Chronically, MPD treatment when comparing adolescent and adult gave the following results: the 0.6 mg/kg dose of MPD failed to cause sensitization in the adolescent group but caused sensitization in the adult group, while the 2.5 and 10 mg/kg both caused sensitization in the adolescent and adult groups.

    The aetiologies of acute pancreatitis in young adult patients are poorly known. To prospectively evaluate the causes of acute pancreatitis in patients aged less than 35 years. Overall, 309 consecutive patients admitted to our centre for acute pancreatitis received first-line investigations, including medical history, standard laboratory tests, abdominal ultrasound and computed tomography. If no aetiology was found, second-line investigations were performed, including endoscopic ultrasound, magnetic-resonance cholangiopancreatography and genetic testing in cases of idiopathic pancreatitis. Overall, 66 patients aged between 16 and 35 years were included. After first-line investigations, 49% of cases of acute pancreatitis remained idiopathic. Second-line investigations reduced this rate to 21%. The frequency of aetiologies for acute pancreatitis significantly differed in adults aged ≤ 35 compared to those aged >35 years: biliary aetiology was less frequent (23% versus 43%, p=0.003) as well as alcohol-related (8% versus 24%, p=0.01); drug-induced was more common (16% versus 4%, p=0.0007), as well as cannabis-related (13% versus 1%, pacute pancreatitis significantly differed in adults aged less than 35 years when compared to older patients. Thus, use of medications, exposure to cannabis, and genetic mutations should be actively sought in these patients. Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.

    Insulin resistance was common in patients with stroke. This study investigated the association between insulin resistance and outcomes in nondiabetic patients with first-ever acute ischemic stroke. Patients with ischemic stroke without history of diabetes mellitus in the ACROSS-China registry (Abnormal Glucose Regulation in Patients With Acute Stroke Across China) were included. Insulin resistance was defined as a homeostatis model assessment-insulin resistance (HOMA-IR) index in the top quartile (Q4). HOMA-IR was calculated as fasting insulin (μU/mL)×fasting glucose (mmol/L)/22.5. Multivariable logistic regression or Cox regression was performed to estimate the association between HOMA-IR and 1-year prognosis (mortality, stroke recurrence, poor functional outcome [modified Rankin scale score 3-6], and dependence [modified Rankin scale score 3-5]). Among the 1245 patients with acute ischemic stroke enrolled in this study, the median HOMA-IR was 1.9 (interquartile range, 1.1-3.1). Patients with insulin resistance were associated with a higher mortality risk than those without (adjusted hazard ratio, 1.68; 95% confidence interval, 1.12-2.53; P =0.01), stroke recurrence (adjusted hazard ratio, 1.57, 95% confidence interval, 1.12-2.19; P =0.008), and poor outcome (adjusted odds ratio, 1.42; 95% confidence interval, 1.03-1.95; P =0.03) but not dependence after adjustment for potential confounders. Higher HOMA-IR quartile categories were associated with a higher risk of 1-year death, stroke recurrence, and poor outcome ( P for trend =0.005, 0.005, and 0.001, respectively). Insulin resistance was associated with an increased risk of death, stroke recurrence, and poor outcome but not dependence in nondiabetic patients with acute ischemic stroke. © 2017 American Heart Association, Inc.

    2013-10-01

    The aim of this review was to systematically identify and synthesise all qualitative evidence on how adult patients diagnosed with acute leukaemia experience living with their illness. A systematic search strategy was developed comprising of two search strings: i) acute leukaemia and ii) qualitative methodology. The search strategy was run in seven electronic databases (Medline, CINAHL, PsychINFO, EMBASE, BNI & Archive, SSCI and ASSIA). Nine qualitative studies in adult patients with acute leukaemia, published in peer reviewed journals between 01/1990 and 01/2013 were included in the final sample. The qualitative thematic synthesis resulted in the development of a conceptual model describing a person's path to build a renewed self. Following the initial blow of diagnosis with the range of initial reactions, patients with acute leukaemia are living in a contracting world; they have to deal with the life in hospital, the several losses and the impact of their illness on their emotions and interpersonal relationships. Several factors take up a buffering role at that stage: coping, support, information and hope. Finally, patients accommodate acute leukaemia in their lives through re-evaluating personal values and assigning new meaning to their experience. Results from this thematic synthesis are indicative of the impact of acute leukaemia on patients' lives and the processes they use to make sense and accommodate the illness in their life. Increasing our understanding of these processes is warranted to improve patient care. Copyright © 2013. Published by Elsevier Ltd.

    Imaging is required in only a minority of patients with urinary tract infection. Some patients who present with severe loin pain are imaged because ureteric colic is suspected.

    Imaging is required in only a minority of patients with urinary tract infection. Some patients who present with severe loin pain are imaged because ureteric colic is suspected. If urinary tract infection does not respond normally to antibiotics, imaging is undertaken to check for evidence of renal obstuction or sepsis. Finally, after the acute infection has been treated, imaging is required in some patients to check for factors pre-disposing to renal damage or to relapsing or recurrent infection. This review discusses the appropriate choice of imaging technique to use in each clinical situation and summarises the expected findings. (orig.). With 15 figs., 1 tab

    Background Patients with chromosome 5 abnormalities and high-risk myelodysplastic syndromes or acute myeloid leukemia have a poor outcome. We hypothesized that increasing doses of lenalidomide may benefit this group of patients by inhibiting the tumor clone, as assessed by fluorescence in situ...... and treated with lenalidomide up to 30 mg daily for 16 weeks. Three patients had isolated del(5q), six had del(5q) plus one additional aberration, 14 had del(5q) and a complex karyotype, four had monosomy 5, and one had del(5q) identified by fluorescence in situ hybridization only. RESULTS: Major and minor...... cytogenetic responses, assessed by fluorescence in situ hybridization, were achieved in 5/26 (19%) and 2/26 (8%) patients, respectively, who received one or more dose of lenalidomide, while two patients achieved only a bone marrow response. Nine of all 26 patients (35%) and nine of the ten who completed...

    Obese adults exhibit increased levels of inflammation, which may negatively affect blood pressure regulation. Based on existing literature, we hypothesized: (1) baroreflex sensitivity would be lower in obese adults when compared to lean adults; (2) acute ibuprofen (IBU, a cyclooxygenase inhibitor and nonsteroidal antiinflammatory agent) administration would increase baroreflex sensitivity in obese adults, with no effect in lean adults. Seven lean (4 male, 3 female) and six obese (5 M, 1 F) adults completed two visits randomized to control (CON) or IBU (800 mg oral). On each visit, blood pressure (intra-arterial catheter), heart rate (ECG), and muscle sympathetic nerve activity (MSNA, microneurography) were measured continuously. Sympathetic and cardiac baroreflex sensitivities were assessed using the modified Oxford technique. Measures of systemic inflammation [C-reactive protein (CRP) and interleukin-6 (IL-6)] were higher in obese adults when compared to lean adults and tended to decrease with IBU (IL-6: p baroreflex sensitivity was lower in obese adults (14 ± 2 vs. 24 ± 2 ms/mmHg, p = 0.02), whereas sympathetic baroreflex sensitivity was higher in obese adults (-3.6 ± 0.5 vs. -2.1 ± 0.5 bursts/100 beats/mmHg, p = 0.03) when compared to lean. There was no effect of IBU on cardiac or sympathetic baroreflex sensitivity in either group (p value range 0.20-0.71). Despite obese individuals exhibiting higher levels of systemic inflammation and lower cardiac baroreflex sensitivity when compared to lean adults, an acute dose of IBU has no effect on cardiac or sympathetic baroreflex sensitivity.

    The World Health Organization classifies atypical chronic myeloid leukemia (aCML) as a myeloproliferative/myelodisplastic hematological disorder. The primary manifestations are leukocytosis with disgranulopoiesis, absence of basophilia and/or monocytosis, splenomegaly and absence of Philadelphia chromosome or BCR/ABL fusion. Overall 50-65% of patients demonstrate karyotypic abnormalities, although no specific cytogenetic alterations have been associated with this disease. X chromosome alterations have been rarely reported in myeloid malignancies. Although Isodicentric X, idic(X)(q13) is well known in females with myelodysplastic syndromes (MDS), little data are available on X isochromosome and its pathogenetic potential in these disorders. i(X)(p10) is observed in a variety of hematologic malignancies, both myeloid and lymphoid, as a unique abnormality, as well as part of a more complex karyotype, in females and less frequently in male patients. The present report describes the first patient with aCML, with documented isolated i(X)(p10), who developed a secondary acute myeloid leukemia (sAML).

    PTEN gene inactivation by mutation or deletion is common in pediatric T-cell acute lymphoblastic leukemia (T-ALL), but the impact on outcome is unclear, particularly in patients with NOTCH1/FBXW7 mutations. We screened samples from 145 patients treated on the MRC UKALL2003 trial for PTEN mutations using heteroduplex analysis and gene deletions using single nucleotide polymorphism arrays, and related genotype to response to therapy and long-term outcome. PTEN loss-of-function mutations/gene deletions were detected in 22% (PTEN(ABN)). Quantification of mutant level indicated that 67% of mutated cases harbored more than one mutant, with up to four mutants detected, consistent with the presence of multiple leukemic sub-clones. Overall, 41% of PTEN(ABN) cases were considered to have biallelic abnormalities (mutation and/or deletion) with complete loss of PTEN in a proportion of cells. In addition, 9% of cases had N- or K-RAS mutations. Neither PTEN nor RAS genotype significantly impacted on response to therapy or long-term outcome, irrespective of mutant level, and there was no evidence that they changed the highly favorable outcome of patients with double NOTCH1/FBXW7 mutations. These results indicate that, for pediatric patients treated according to current protocols, routine screening for PTEN or RAS abnormalities at diagnosis is not warranted to further refine risk stratification.

    This study compared the effect of acute caffeine ingestion on coincidence timing accuracy in younger and older adults. Thirteen young (aged 18-25 years, age: 20 ± 2 years, 7 females, 5 males) and 13 older (aged 61-77 years, age: 68 ± 6 years, 9 females, 3 males) adults, all who were habitual moderate caffeine consumers undertook measures of coincident anticipation timing performance pre- and post-acute caffeine (3 mg/kg) or placebo ingestion administered in a double blind, randomized fashion. Results indicated significant pre-to-post X substance (caffeine vs. placebo) interactions for absolute (P = 0.02, Pη(2) = 0.204) and variable error (P = 0.015, Pη(2) = 0.221). In both cases, error (absolute or variable) improved pre-to-post ingestion in the caffeine condition but not in the placebo condition. There were no significant differences due to age (younger vs. older adults, P > 0.05) in any of the analyses. The results of this study suggest that acute caffeine ingestion positively influence coincidence anticipation timing performance in both younger and older adults, who are moderate habitual caffeine consumers. Such effects might therefore be useful for older adults in enhancing ability to undertake cognitive-perceptual tasks which involve interceptive actions.

    Chrysanthemum indicum is widely used to treat immune-related and infectious disorders in East Asia. C. indicum flower oil contains 1,8-cineole, germacrene D, camphor, α-cadinol, camphene, pinocarvone, β-caryophyllene, 3-cyclohexen-1-ol, and γ-curcumene. We evaluated the safety of C. indicum flower oil by conducting acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation tests. Mortality, clinical signs and gross findings of mice were measured for 15 days after the oral single gavage administration of C. indicum flower oil. There were no mortality and clinical signs of toxicity at 2,000 mg/kg body weight/day of C. indicum flower oil throughout the 15 day period. Micronucleated erythrocyte cell counts for all treated groups were not significantly different between test and control groups. Levels of 15.63~500 μg C. indicum flower oil/plate did not induce mutagenicity in S. Typhimurium and E. coli, with or without the introduction of a metabolic activation system. These results indicate that ingesting C. indicum flower oil produces no acute oral toxicity, bone marrow micronucleus, and bacterial reverse mutation.

    Interstitial cells of Cajal (ICC) are fundamental regulators of GI motility. Here, we report the manometrical abnormalities and abnormalities of ICC distribution and ultrastructure encountered in a 30-yr-old patient with megaduodenum and pseudo-obstruction. Full thickness biopsies taken during...... laparoscopic placement of a jejunostomy showed vacuolated myocytes and fibrosis predominantly in the outer third of the circular muscle layer of the duodenum, suggestive for visceral myopathy. The distribution of ICC was also strikingly abnormal: by light microscopy, ICC surrounding the myenteric plexus were...... lacking in the megaduodenum, whereas ICC were normally present in the duodenal circular muscle and in the jejunum. By electron microscopy, very few ICC were identified around the duodenal myenteric plexus. These findings suggest that abnormalities in ICC may contribute to the disturbed motility in some...

    In order to assess the CT diagnosis of suspected acute appendicitis, we performed abdominal contrasted CT measurements in 77 patients from 20 to 86 years old, and of 50 men and 27 women from June 1993 to June 1996. The surgical findings were compared with the preoperative CT findings. By the preoperative CT imaging, we can know the degree and the position of inflammation in appendix vermiformis and the degree and the spread of periappendicular inflammation in the case of appendicitis, and can make a differential diagnosis of diverticulitis or gynecological diseases from appendicitis. It is important to make a preoperative diagnosis by the objectively excellent abdominal CT imaging and to avoid unnecessary surgery. (K.H.)

    1988-01-01

    A 21-year-old woman with acute lymphoblastic leukemia presented with central neurologic symptoms immediately after the second irradiation (20 Gy to the brain and 10 Gy to the spinal cord) for central nervous system (CNS)-leukemia 3 years and 2 months after the first cranial irradiation with 20 Gy. White matter was depicted as diffusely high density area on CT; histology revealed necrosis of leukemic cells. In the present patient with repeated recurrent CNS-leukemia, leukemic cells seemed to have been damaged simultaneously after irradiation because of parenchymal widespread involvement of leukemic cells, resulting in brain edema, an increased intracranial pressure and parenchymal disturbance. This finding may have an important implication for the risk of cranial irradiation in the case of widespread involvement of leukemic cells. Re-evaluation of cranial irradiation in such cases is suggested. (Namekawa, K.)

  5. Abnormal chloride homeostasis in the substancia nigra pars reticulata contributes to locomotor deficiency in a model of acute liver injury.

    Directory of Open Access Journals (Sweden)

    Yan-Ling Yang

    Full Text Available BACKGROUND: Altered chloride homeostasis has been thought to be a risk factor for several brain disorders, while less attention has been paid to its role in liver disease. We aimed to analyze the involvement and possible mechanisms of altered chloride homeostasis of GABAergic neurons within the substantia nigra pars reticulata (SNr in the motor deficit observed in a model of encephalopathy caused by acute liver failure, by using glutamic acid decarboxylase 67 - green fluorescent protein knock-in transgenic mice. METHODS: Alterations in intracellular chloride concentration in GABAergic neurons within the SNr and changes in the expression of two dominant chloride homeostasis-regulating genes, KCC2 and NKCC1, were evaluated in mice with hypolocomotion due to hepatic encephalopathy (HE. The effects of pharmacological blockade and/or activation of KCC2 and NKCC1 functions with their specific inhibitors and/or activators on the motor activity were assessed. RESULTS: In our mouse model of acute liver injury, chloride imaging indicated an increase in local intracellular chloride concentration in SNr GABAergic neurons. In addition, the mRNA and protein levels of KCC2 were reduced, particularly on neuronal cell membranes; in contrast, NKCC1 expression remained unaffected. Furthermore, blockage of KCC2 reduced motor activity in the normal mice and led to a further deteriorated hypolocomotion in HE mice. Blockade of NKCC1 was not able to normalize motor activity in mice with liver failure. CONCLUSION: Our data suggest that altered chloride homeostasis is likely involved in the pathophysiology of hypolocomotion following HE. Drugs aimed at restoring normal chloride homeostasis would be a potential treatment for hepatic failure.

    Full Text Available &lt;b&gt;Purpose:&lt;/b&gt; In children with acute leukemia, bone marrow genetic abnormalities (GA have prognostic significance, and may be the basis for minimal residual disease monitoring. Since April 2007, we have used a multiplex reverse transcriptase-polymerase chain reaction tool (HemaVision to detect of GA. &lt;b&gt;Methods:&lt;/b&gt; In this study, we reviewed the results of HemaVision screening in 270 children with acute leukemia, newly diagnosed at The Catholic University of Korea from April 2007 to December 2011, and compared the results with those of fluorescence in situ hybridization (FISH, and G-band karyotyping. &lt;b&gt;Results:&lt;/b&gt; Among the 270 children (153 males, 117 females, 187 acute lymphoblastic leukemia and 74 acute myeloid leukemia patients were identified. Overall, GA was detected in 230 patients (85.2%. HemaVision, FISH, and G-band karyotyping identified GA in 125 (46.3%, 126 (46.7%, and 215 patients (79.6%, respectively. TEL-AML1 (20.9%, 39/187 and AML1-ETO (27%, 20/74 were the most common GA in ALL and AML, respectively. Overall sensitivity of HemaVision was 98.4%, with false-negative results in 2 instances: 1 each for TEL-AML1 and MLL-AF4 . An aggregate of diseasesspecific FISH showed 100% sensitivity in detection of GA covered by HemaVision for actual probes utilized. G-band karyotype revealed GA other than those covered by HemaVison screening in 133 patients (49.3%. Except for hyperdiplody and hypodiploidy, recurrent GA as defined by the World Health Organizationthat were not screened by HemaVision, were absent in the karyotype. &lt;b&gt;Conclusion:&lt;/b&gt; HemaVision, supported by an aggregate of FISH tests for important translocations, may allow for accurate diagnosis of GA in Korean children with acute leukemia.

    Acute hemicerebellitis, marked by headache with or without cerebellar signs, is a rare clinical entity involving a unilateral cerebellar hemisphere. The pathogenesis of acute hemicerebellitis remains unclear, and the disease rarely occurs in adults. Here, we report an 18-year-old woman who presented with a lack of coordination of the right hand and leg lasting longer than one week, following a pulsatile headache. A neurological examination disclosed ocular dysmetria, right-sided limb ataxia and slight truncal ataxia. Cerebrospinal fluid analysis showed mononuclear pleocytosis. The serology and autoimmune studies were unremarkable. Brain magnetic resonance imaging (MRI) revealed a focal signal change in the right cerebellar hemisphere and vermis. Acute hemicerebellitis was diagnosed, and the patient was treated with intravenous methylprednisolone sodium succinate and acyclovir. Subsequently, the headache resolved, and the cerebellar signs were markedly improved. Twenty days after admission, she became asymptomatic and brain MRI showed resolution of cerebellar hyperintensity on the right side. In conclusion, we identified only 6 additional patients with adult-onset acute hemicerebellitis from previous reports, highlighting the importance of recognizing this rare clinical entity. Its clinical outcome is usually favorable, but in the acute phase, attention should be directed toward clinical symptoms that are suggestive of increased intracranial pressure.

    Full Text Available Acute myocardial infarction (AMI is rarely associated with antiphospholipid syndrome. The treatment of these patients is a clinical challenge. We report the observations of 2 young adults (1 woman and 1 man, admitted in our acute care unit for acute myocardial infarction (AMI. A coagulopathy work-up concludes the existence of antiphospholipid syndrome (APS in the 2 cases. APS syndrome was considered primary in 2 cases. All patients presented an intense inflammatory syndrome (high level of CRP. Anticardiolipine was present in the 2 cases. However, anti B2 glycoprotein I antibodies were detected in only one case. Emergency percutaneous transluminal coronary angioplasty (PTCA with direct stenting had been performed successfully only in the first case, and the follow-up was uncomplicated. Thereafter, long-term oral anticoagulant appeared to be effective. The last patient was admitted because of peripheral acute ischemia of legs. Standard electrocardiogram showed signs of previous silent anteroseptal wall myocardial infarction confirmed by echocardiography. The latter revealed an apical thrombus and a very low left ventricular ejection fraction. Amputation of the right leg was necessary because of consultation occurred too late. However, he died four weeks later. Primary antiphospholipid syndrome should be considered as a cause of acute myocardial infarction in young adults, and PTCA with anticoagulant treatment is effective for initial treatment of this complication

    Acute leukemias of ambiguous lineage represent a heterogeneous group of rare, poorly characterized leukemias with adverse outcome. No larger studies have yet performed a combined approach of molecular and clinical characterization of acute undifferentiated leukemia (AUL) and biphenotypic acute leukemia (BAL) in adults. Here we describe 16 adults with AUL and 26 with BAL and performed mutational as well as expression studies of genes with prognostic impact in acute leukemia (BAALC, ERG, MN1, WT1, and IGFBP7). AUL showed overexpression of these genes compared to T-lymphoblastic leukemia (T-ALL), B-precursor ALL, and to acute myeloid leukemia (AML). Genotype alterations were not detectable in AUL. BAL samples were characterized by frequent WT1 mutations (18 %) and BCR-ABL translocations (30 %). ALL-based treatment protocols induced complete remissions in 40 % and AML-like therapies in 22 % of AUL/BAL patients. The outcome in both groups was very poor; a long-term survival was only observed in patients undergoing allogeneic stem cell transplantation (SCT). Our findings indicate that AUL and BAL share important molecular and high-risk features of both myeloid and lymphoid leukemias. BAL patients exhibited genetic alterations, which can be targeted therapeutically. Importantly, ALL therapy might be more effective than AML protocols and AUL/BAL patients should be considered for allogeneic SCT.

    2012-02-03

    INTRODUCTION: The combination of ageing, illness, and medications can lead to hyponatraemia or hypernatraemia. AIMS: To describe the distribution of plasma sodium levels in older patients admitted to hospital. METHODS: We carried out a hospital based cross-sectional study examining 1,511 serum sodium concentrations ([Na+]) among 336 elderly patients and attempted to elucidate the cause(s) of the abnormal serum [Na+]. RESULTS: The study population had a mean age of 81.4. Ninety-two (27.4%) patients had hyponatraemia and seven patients (2.1%) had hypernatraemia during their hospitalisation. The distribution of [Na+] results was towards the lower end of the normal range. The mortality rate of patients with hyponatraemia was 14.1% and that of patients with normal serum [Na+] was 8.9%. Six patients with hypernatraemia died in hospital. Lower respiratory tract infection and medication accounted for the majority of cases. CONCLUSIONS: Deranged [Na+] is common among elderly patients admitted to hospital.

    Capture ELISAs with biotinylated monospecific antibodies were developed to detect both C-reactive protein (CRP) and haptoglobin (Hp) in serum of adult periodontitis (AP) patients and normal subjects. Each acute-phase reactant was significantly increased in serum from AP patients with CRP at 9.12 ±1.61 mg/l versus 2.17 ± 0.41 mg/l (P acute-phase reactants. The conclusions are that either these molecules are formed locally and distributed to the serum, or these presumably localized infections impact upon the systemic components of the host protective responses.

    The purpose of the present study was to examine the acute effects of resting, aerobic exercise practised alone, and aerobic exercise with active video games (AVG), on complex reaction time (CRT) and the post-exercise acute rate of perceived exertion (RPE) in young healthy adults. The experimental group was composed of 92 healthy young adults, 78 males and 13 females (age M = 21.9 ± 2.7 years) who completed two sessions, A and B. In session A, participants rode 30 min on an ergometer, while in session B they exercised for 30 min on an ergometer while playing an AVG on a Wii. The control group was composed of 30 young adults, 26 males and 4 females (age M = 21.4 ± 2.9 years) who rested for 30 min. In each session, a CRT task was performed before and after exercising or resting, and post-exercise global RPE was noted. Repeated measures general linear model (GLM) and Wilcoxon tests were performed. (1) Both aerobic exercise alone and aerobic exercise combined with AVG improved CRT, while resting did not; (2) aerobic exercise combined with AVG did not improve CRT more than aerobic exercise only; and (3) RPE was lower after aerobic exercise combined with AVG compared with aerobic exercise only. In young adults, exercise produces acute benefits on CRT, and practising exercise with AVG helps to decrease RPE.

  14. Diagnostic imaging of acute abdominal pain in adults.

    Cartwright, Sarah L; Knudson, Mark P

    2015-04-01

    Acute abdominal pain is a common presentation in the outpatient setting and can represent conditions ranging from benign to life-threatening. If the patient history, physical examination, and laboratory testing do not identify an underlying cause of pain and if serious pathology remains a clinical concern, diagnostic imaging is indicated. The American College of Radiology has developed clinical guidelines, the Appropriateness Criteria, based on the location of abdominal pain to help physicians choose the most appropriate imaging study. Ultrasonography is the initial imaging test of choice for patients presenting with right upper quadrant pain. Computed tomography (CT) is recommended for evaluating right or left lower quadrant pain. Conventional radiography has limited diagnostic value in the assessment of most patients with abdominal pain. The widespread use of CT raises concerns about patient exposure to ionizing radiation. Strategies to reduce exposure are currently being studied, such as using ultrasonography as an initial study for suspected appendicitis before obtaining CT and using low-dose CT rather than standard-dose CT. Magnetic resonance imaging is another emerging technique for the evaluation of abdominal pain that avoids ionizing radiation.

    2011-08-01

    Full Text Available Abstract Background The purpose of the present study was to determine how acute adult and/or prior early-in life (EIL; P14-P16 exposure to bladder inflammation affects bladder content of calcitonin gene related peptide (CGRP and substance P (SP. Estrous cycle influences were also studied in the adult-treatment conditions. Methods In Experiment 1, intravesical zymosan or isoflurane anesthesia alone was administered to adult female rats. Bladders and serum were collected 24 hours later during each phase of the estrous cycle. In Experiment 2, zymosan or anesthesia alone was administered EIL and as adults, with bladder tissue collection 24 h later. Results In general, Experiment 1 showed that bladder content of both CGRP and SP was increased by inflammation. This effect was significant when data were collapsed across all phases of the estrous cycle, but was only significant during proestrus when individual comparisons were made during each phase of estrous. Also, adult bladder inflammation significantly reduced estradiol levels. In Experiment 2, bladder content of CGRP and SP was significantly increased in rats receiving EIL and/or adult inflammation. Bladder weights were also significantly increased by inflammation. Conclusions These data indicate that bladder CGRP and SP are maximally increased during the proestrus phase of the estrous cycle in inflamed adult female rats. EIL exposure to bladder inflammation alone can also produce an increase in CGRP and SP lasting into adulthood. Therefore, EIL experience with bladder inflammation may predispose an organism to experience a painful bladder disorder as an adult by increasing primary afferent content of CGRP and/or SP.

    There has been increasing interest and research into sarcopenia in community-dwelling older adults since the European Working Group on Sarcopenia in Older People (EWGSOP) agreed a consensus definition in 2010. Sarcopenia has been defined as loss of muscle mass with loss of muscle function (strength or physical performance), with measurements two Standard Deviations (SDs) below the mean of a young reference population. This definition does not necessitate longitudinal measurements, or the absence of acute illness and diagnosis can be made from single measurements. We hypothesise that hospitalisation, due to a combination of acute inflammatory burden and muscle disuse, leads to an acute decline in muscle mass and function and may lead to some individuals meeting criteria for sarcopenia, acutely, based on the EWGSOP definition. This may be partially recoverable or may lead to increased risk of developing sarcopenia long-term. We have denoted the term “acute sarcopenia” to refer to acute loss of muscle mass and function associated with hospitalisation. This review discusses some of the current available research in this context and also identifies some of the knowledge gaps and potential areas for future research. PMID:29392090

    We evaluated the efficacy of contrast-enhanced ultrasonography (CEUS) in detecting acute pyelonephritis (APN) using the rabbit kidney model and compared it with CT and MRI. This study was approved by the Institutional Review Board. In a total of 20 New Zealand White rabbits, APN was induced experimentally. CEUS, CT, and MRI were performed on the first, third, and seventh postoperative days. After imaging studies, the subjects were sacrificed and the pathological diagnosis of APN was confirmed in each animal by a pathologist. Imaging studies were obtained in eight animals, including eight CEUS, four computed tomography (CT), and four magnetic resonance imaging (MRI) images. CEUS depicted diffuse renal enlargement (7), diffuse heterogeneous parenchymal enhancement (6), and focal areas of decreased parenchymal enhancement (6). These findings were well correlated with the CT and MRI findings in five cases in which these studies were available. CT and MRI showed diffuse renal enlargement, diffuse heterogeneous parenchymal enhancement, focal areas of decreased parenchymal enhancement, focal contour bulging, and the finding of perinephric spread of infection. In a rabbit model, CEUS could depict the parenchymal lesions of APN similar to CT or MRI; however, it was limited in depicting the perinephric extension of inflammation.

    We studied the role of early diffusion-weighted imaging DWI in the investigation of children with new-onset prolonged seizures which eventually result in unilateral hippocampal sclerosis (HS). We carried out MRI on five children aged 17 months to 7 years including conventional and diffusion-weighted sequences. We calculated apparent diffusion coefficients (ADC) for the affected and the normal opposite hippocampus. Follow-up examinations were performed, including DWI and ADC measurements in four. We studied four children within 3 days of the onset of prolonged psychomotor seizures and showed increased signal on T2-weighted images, and DWI, indicating restricted diffusion, throughout the affected hippocampus. The ADC were reduced by a mean of 14.4% in the head and by 15% in the body of the hippocampus. In one child examined 15 days after the onset of seizures, the ADC were the same on both sides. All five patients showed hippocampal atrophy on follow-up 2-18 months later. In the four patients in whom ADC were obtained on follow-up, they were increased by 19% in the head and 17% in the body. DWI may represent a useful adjunct to conventional MRI for identifying acute injury to the hippocampus which results in sclerosis. (orig.)

    Acute care units (ACUs) with focused sickle cell disease (SCD) care have been shown to effectively address pain and limit hospitalizations compared to emergency departments (ED), the reason for differences in admission rates is understudied. Our aim was compare effects of usual care for adult SCD pain in ACU and ED on opioid doses and discharge pain ratings, hospital admission rates and lengths of stay. In a retrospective, comparative cohort, single academic tertiary center study, 148 adults with sickle cell pain received care in the ED, ACU or both. From the medical records we documented opioid doses, unit discharge pain ratings, hospital admission rates, and lengths of stay. Pain on admission to the ED averaged 8.7±1.5 and to the ACU averaged 8.0±1.6. The average pain on discharge from the ED was 6.4±3.0 and for the ACU was 4.5±2.5. 70% of the 144 ED visits resulted in hospital admissions as compared to 37% of the 73 ACU visits. Admissions from the ED or ACU had similar inpatient lengths of stay. Significant differences between ED and ACU in first opioid dose and hourly opioid dose were noted. Applying guidelines for higher dosing of opioids for acute painful episodes in adults with SCD in ACU was associated with improved pain outcomes and decreased hospitalizations, compared to ED. Adoption of this approach for SCD pain in ED may result in improved outcomes, including a decrease in hospital admissions. Published by Elsevier Inc.

    Full Text Available Poisoning is a frequent cause of referral to medical emergencies and a major health problem around the world, especially in developing countries. We aimed to review the epidemiology and pattern of adult poisoning in Iran in order to facilitate the early diagnosis and management of poisoning. The pattern of poisoning is different in various parts of Iran. Pharmaceutical compounds were the most common cause of poisoning in most parts of Iran. Pesticide-related toxicities were more common in northern agricultural regions, whereas bites and stings were seen more commonly in southern Iran. Carbon monoxide poisoning was common in cities with many motor vehicles such as Tehran and in colder climates such as in northern and western regions due to inadequately vented gas appliances such as stoves and heaters. Majoon Birjandi (containing cannabis is a unique substance used in eastern Iran. Poisoning by opioids, tramadol, and pesticides (organophosphate and aluminum phosphide has remained a common hazard in Iran. Poisoning-associated morbidity and mortality rates vary by region and have changed over time due to the introduction of new drugs and chemicals. Early diagnosis and proper treatment may be lifesaving; thus, understanding the general pattern of poisoning in different regions is important.

    2013-03-01

    As adults with cerebral palsy (CP) are surviving longer, interventions are needed to reduce spasticity and increase strength to improve mobility and life quality. Adults with CP are lacking a form of independent exercise that allows them to maintain or improve their ambulation skills. A new approach to increase muscle strength and flexibility called whole-body vibration (WBV) was assessed. Using an individualized frequency (I-Freq) approach to WBV therapy the acute effects on gait in adults with CP was measured. In this study, eight adults with CP (age 20-51 years, two female) participated in two testing sessions: session one determined each individual's I-Freq; and session two included a 3D gait analysis before and after a WBV treatment. The WBV was administered in five, one minute bouts of vibration followed by one minute of rest. Following WBV exposure subjects experienced a significant increase in walking speed (P=0.047), stride length (P=0.017) and dynamic ankle range of motion (P=0.042). These data show that acute WBV treatments at I-Freq can improve measures of gait and mobility in adults with CP, however, future should assess potential long-term improvements.

    Intussusception in adults is very rarely seen, and this cause acute abdomen. A computed tomography (CT) scan, clinical suspicion, history, and a physical examination are important for the diagnosis. We present two cases of colonic intussusceptions induced by lipoma. The cases had similar locations, diagnoses, and management. Both lipomas were located close to the cecum in the ascending colon, and a right segmental colon resection was performed in both cases. The follow-up of both cases was uneventful. Although benign lesions can cause colonic intussusception, the high incidence of malignancy in colonic lesions should always be considered. Therefore, oncologic surgical procedures should be applied. The definitive diagnosis can be made by histopathology. Sertkaya M, Emre A, Pircanoglu EM, Yazar FM, Tepe M, Cengiz E, Isler A, Vicdan H.

    Little is known regarding sustainability of evidence-based practices (EBPs) following implementation. This article reports sustainability of evidence-based acute pain management practices in hospitalized older adults following testing of a multifaceted Translating Research Into Practice (TRIP) implementation intervention. A cluster randomized trial with follow-up period was conducted in 12 Midwest U.S. hospitals (six experimental, six comparison). Use of evidence-based acute pain management practices and mean pain intensity were analyzed using generalized estimating equations across two time points (following implementation and 18 months later) to determine sustainability of TRIP intervention effects. Summative Index scores and six of seven practices were sustained. Experimental and comparison group differences for mean pain intensity over 72 hours following admission were sustained. Results revealed most evidence-based acute pain management practices were sustained for 18 months following implementation. Further work is needed to identify factors affecting sustainability of EBPs to guide development and testing of sustainability strategies.

    Full Text Available BACKGROUND: Perianal infection is a common problem for patients with acute leukemia. However, neutropenia and bleeding tendency are relatively contraindicated to surgical intervention. The epidemiology, microbiology, clinical manifestations and outcomes of perianal infection in leukemic patients are also rarely discussed. METHOD: The medical records of 1102 adult patients with acute leukemia at a tertiary medical center in Taiwan between 2001 and 2010 were retrospectively reviewed and analyzed. RESULT: The prevalence of perianal infection was 6.7% (74 of 1102 in adult patients with acute leukemia. Twenty-three (31% of the 74 patients had recurrent episodes of perianal infections. Patients with acute myeloid leukemia had higher recurrent rates than acute lymphoblastic leukemia patients (p = 0.028. More than half (n = 61, 53% of the perianal infections were caused by gram-negative bacilli, followed by gram-positive cocci (n = 36, 31%, anaerobes (n = 18, 15% and Candida (n = 1, 1% from pus culture. Eighteen patients experienced bacteremia (n = 24 or candidemia (n = 1. Overall 41 (68% of 60 patients had polymicrobial infection. Escherichia coli (25% was the most common micro-organism isolated, followed by Enterococcus species (22%, Klebsiella pneumoniae (13%, and Bacteroides species (11%. Twenty-five (34% of 74 patients received surgical intervention. Acute leukemia patients with surgically managed anal fistulas tended to have fewer recurrences (p = 0.067. Four (5% patients died within 30 days after diagnosis of perianal infection. Univariate analysis of 30-day survival revealed the elderly (≧ 65 years (p = 0.015 and patients with shock (p<0.001 had worse outcome. Multivariate analysis showed septic shock to be the independent predictive factor of 30-day crude mortality of perianal infections (p = 0.016. CONCLUSION: Perianal infections were common and had high recurrence rate in adult patients with acute

    To explore perceived exercise benefits and barriers in adults with acute leukemia who recently completed an inpatient exercise intervention during induction therapy.
. Descriptive, exploratory design using semistructured interviews.
. Inpatient hematology/oncology unit at North Carolina Cancer Hospital in Chapel Hill.
. 6 adults with acute leukemia aged 35-67 years.
. Content analyses of semistructured interviews that were conducted with each participant prior to hospital discharge.
. Most participants were not meeting the recommended physical activity levels of 150 minutes of moderate-intensity exercise per week before their diagnosis. Patients were highly pleased with the exercise intervention and the overall program. Common barriers to exercise were anxiety and aches and pains.
. Overall, participants experienced physical and psychological benefits with the exercise intervention with no adverse events from exercising regularly during induction chemotherapy. Referrals for cancer rehabilitation management will lead to prolonged recovery benefits.
. Findings inform the nurses' role in encouraging and supporting adults with acute leukemia to exercise and be physically active during their hospitalization. Nurses should also be responsible for assisting patients with physical function activities to increase mobility and enhance overall health-related quality of life.

    During the acute phase of HIV infection, large CD4+ T-cell depletion occurs in the gastrointestinal tract. The kinetics of CD4+ T-cell decrease and highly active antiretroviral therapy (HAART)-mediated immune reconstitution were evaluated. Rectosigmoid colonic (RSC) biopsies and blood samples of nine patients with acute HIV infection were collected. CD4+ T-cell count, HIV RNA, intracellular HIV DNA and messenger RNA cytokine expression were evaluated before and after 6 months of HAART. All nine patients presented symptomatic retroviral infection. Early HAART was associated with a sustained and comparable reduction of HIV RNA in plasma, peripheral blood mononuclear cells (PBMCs) and RSC biopsies. HIV DNA decreased in PBMCs, but was only marginally reduced in RSC biopsies. Comparisons between reduction rates of HIV DNA in these two compartments confirmed that HIV DNA clearance was less efficient in RSC biopsies compared with PBMCs. Assessment of immunological profiles in PBMCs and RSC biopsies showed that the T-helper (Th)1-like/Th2-like ratio was sharply decreased in RSC biopsies and increased in PBMCs throughout the study period. A persistent Th2-like profile was detected in RSC biopsies. Efficient clearing of HIV DNA observed in PBMCs correlated with the establishment of a more favourable Th1-like profile. A less efficient clearance of intracellular HIV DNA following early introduction of HAART is associated with persistent immunological impairment in gut-associated lymphoid tissue (GALT), which is reflected by the skewed expression of cytokines in this reservoir. The present study shows that early initiation of HAART, in the short-term, is not effective in containing the establishment of HIV infection and in reversing associated immunological GALT abnormalities.

    Full Text Available Objective. Several studies showed better outcome in adolescents and young adults with acute lymphoblastic leukemia (ALL treated with pediatrics protocols than similarly aged patients treated with adults protocols, while other studies showed similar outcome of both protocols. We conducted this study to compare the outcome of our pediatrics and adults therapeutic protocols in treatment of adolescents ALL. Patients and Methods. We retrospectively reviewed files of 86 consecutive adolescent ALL patients aged 15–18 years who attended to outpatients clinic from January 2003 to January 2010. 32 out of 86 were treated with pediatrics adopted BFM 90 high risk protocol while 54 were treated with adults adopted BFM protocol. We analyzed the effect of different treatment protocols on achieving complete remission (CR, disease-free survival (DFS, and overall survival (OS. Results. The 2 patients groups have almost similar characteristics. The CR was significantly higher in pediatrics protocol 96% versus 89% (P=0.001. Despite the fact that the toxicity profiles were higher in pediatrics protocol, they were tolerable. Moreover, the pediatrics protocol resulted in superior outcome in EFS 67% versus 39% (P=0.001, DFS 65% versus 41% (P=0.000, and OS 67% versus 45% (P=0.000. Conclusion. Our study’s findings recommend using intensified pediatrics inspired protocol to treat adolescents with acute lymphoblastic leukemia.

    To examine use of magnetic resonance imaging (MRI) of knees with no radiographic evidence of osteoarthritis to determine the prevalence of structural lesions associated with osteoarthritis and their relation to age, sex, and obesity. Population based observational study. Community cohort in Framingham, MA, United States (Framingham osteoarthritis study). 710 people aged >50 who had no radiographic evidence of knee osteoarthritis (Kellgren-Lawrence grade 0) and who underwent MRI of the knee. Prevalence of MRI findings that are suggestive of knee osteoarthritis (osteophytes, cartilage damage, bone marrow lesions, subchondral cysts, meniscal lesions, synovitis, attrition, and ligamentous lesions) in all participants and after stratification by age, sex, body mass index (BMI), and the presence or absence of knee pain. Pain was assessed by three different questions and also by WOMAC questionnaire. Of the 710 participants, 393 (55%) were women, 660 (93%) were white, and 206 (29%) had knee pain in the past month. The mean age was 62.3 years and mean BMI was 27.9. Prevalence of "any abnormality" was 89% (631/710) overall. Osteophytes were the most common abnormality among all participants (74%, 524/710), followed by cartilage damage (69%, 492/710) and bone marrow lesions (52%, 371/710). The higher the age, the higher the prevalence of all types of abnormalities detectable by MRI. There were no significant differences in the prevalence of any of the features between BMI groups. The prevalence of at least one type of pathology ("any abnormality") was high in both painful (90-97%, depending on pain definition) and painless (86-88%) knees. MRI shows lesions in the tibiofemoral joint in most middle aged and elderly people in whom knee radiographs do not show any features of osteoarthritis, regardless of pain.

    The aim of this report was to investigate the tailored treatment strategies for isolated central nervous system (CNS) recurrence in adult patients with acute myeloid leukemia (AML). Isolated CNS recurrence was documented in 34 patients: there were 18, 6, and 10 patients with meningeal involvement type (type A), cranial nerve palsy type (type B), and myeloid sarcoma type (type C), respectively. For patients with type A, intrathecal chemotherapy was the predominant strategy. For type B, systemic HD-Ara-C with four cycles was the main treatment. For type C, cranial irradiation or craniospinal irradiation was adopted and two cycles of HD-Ara-C were given after the irradiation. The 5-year cumulative incidence of CNS recurrence was 12.8%. There was a significantly higher WBC count (32.6∼60.8 × 10(9)/l) in patients at first diagnosis who developed CNS recurrence (all of the three types) compared with patients with no CNS recurrence (10.1 × 10(9)/l) (P = 0.005). We found that a significantly more patients with AML-M5 and 11q23 abnormalities developed CNS recurrence in type A (P < 0.001, 0.005). Twenty-four out of 34 patients (70.6%) with CNS recurrence achieved CNS complete remission at a median of 58 days (range, 30-120). The 3-year disease-free survival and overall survival estimates for all CNS recurrence patients were 21.6 and 25.3%, respectively. This report indicates that the tailored CNS-directed strategy is an effective modality to treat CNS recurrence in adult AML, but further studies are needed to improve the long-term survival.

    Although the survival rate for adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) has steadily improved over the past several decades, it still lags behind that of younger children. This Review explores the reasons for this discrepancy and potential solutions, focusing on patients aged 15-22 years. Recent studies that compared the outcome of AYA patients with ALL treated on pediatric or adult clinical trials have shown substantially better outcomes for this patient population obtained with the pediatric trials. Excellent early results have been obtained for patients with ALL aged up to 40-60 years who were treated in adult study groups with pediatric-based regimens. Targeting biological and socio-political features unique to AYA ALL has reduced the 'AYA gap' and has provided the foundation for basic science and translational and clinical AYA initiatives that are charged with the task of discovering further methods to improve the outcome of AYA with ALL.

    Background Antibiotics play an important role in the treatment of many surgical diseases that affect older adults, and the potential for inappropriate use of these drugs is high. Our objective was to describe antibiotic use among older adults admitted to an acute care surgery service at a tertiary care teaching hospital. Methods Detailed data regarding diagnosis, comorbidities, surgery and antibiotic use were retrospectively collected for patients 70 years and older admitted to an acute care surgery service. We evaluated antibiotic use (perioperative prophylaxis and treatment) for appropriateness based on published guidelines. Results During the study period 453 patients were admitted to the acute care surgery service, and 229 underwent surgery. The most common diagnoses were small bowel obstruction (27.2%) and acute cholecystitis (11.0%). In total 251 nonelective abdominal operations were performed, and perioperative antibiotic prophylaxis was appropriate in 49.5% of cases. The most common prophylaxis errors were incorrect timing (15.5%) and incorrect dose (12.4%). Overall 206 patients received treatment with antibiotics for their underlying disease process, and 44.2% received appropriate first-line drug therapy. The most common therapeutic errors were administration of second- or third-line antibiotics without indication (37.9%) and use of antibiotics when not indicated (12.1%). There was considerable variation in the duration of treatment for patients with the same diagnoses. Conclusion Inappropriate antibiotic use was common among older patients admitted to an acute care surgery service. Quality improvement initiatives are needed to ensure patients receive optimal care in this complex hospital environment. PMID:28930045

    The role of popliteal cysts and subgastrocnemius bursitis in knee joint homeostasis is uncertain. The aim of this study is to describe cross-sectional associations between popliteal cysts, subgastrocnemius bursitis, knee symptoms and structural abnormalities in older adults. A cross-sectional sample of 900 randomly-selected subjects (mean age 63 years, 48% female) were studied. Knee pain, stiffness and dysfunction were assessed by self-administered Western Ontario McMaster Osteoarthritis Index (WOMAC) questionnaire. Radiographic knee osteophyte and joint space narrowing (JSN) were recorded. Magnetic resonance imaging (MRI) was utilized to assess popliteal cysts, subgastrocnemius bursitis, cartilage defects and bone marrow lesions (BMLs). Popliteal cysts were present in 11.7% and subgastrocnemius bursitis in 12.7% of subjects. Subgastrocnemius bursitis was more common in those with popliteal cyst (36.2% versus 9.7%, P bursitis was associated with increased osteophytes and JSN in the medial tibiofemoral compartment. Both were significantly associated with cartilage defects in all compartments, and with BMLs in the medial tibiofemoral compartment. Furthermore, both popliteal cysts and subgastrocnemius bursitis were significantly associated with increased weight-bearing knee pain but these associations became non-significant after adjustment for cartilage defects and BMLs. Popliteal cysts and subgastrocnemius bursitis are associated with increased symptoms as well as radiographic and MRI-detected joint structural abnormalities. Longitudinal data will help resolve if they are a consequence or a cause of knee joint abnormalities.

    Adolescent rats display reduced sensitivity to many dysphoria-related effects of alcohol (ethanol) including motor ataxia and sedative hypnosis, but the underlying neurobiological factors that contribute to these differences remain unknown. The cyclic adenosine monophosphate (cAMP)-dependent protein kinase A (PKA) pathway, particularly the type II regulatory subunit (RII), has been implicated in ethanol-induced molecular and behavioral responses in adults. Therefore, the current study examined cerebral cortical PKA in adolescent and adult ethanol responses. With the exception of early adolescence, PKA RIIα and RIIβ subunit levels largely did not differ from adult levels in either whole cell lysate or P2 synaptosomal expression. However, following acute ethanol exposure, PKA RIIβ P2 synaptosomal expression and activity were increased in adults, but not in adolescents. Behaviorally, intracerebroventricular administration of the PKA activator Sp-cAMP and inhibitor Rp-cAMP prior to ethanol administration increased adolescent sensitivity to the sedative-hypnotic effects of ethanol compared to controls. Sp-cAMP was ineffective in adults whereas Rp-cAMP suggestively reduced loss of righting reflex (LORR) with paralleled increases in blood ethanol concentrations. Overall, these data suggest that PKA activity modulates the sedative/hypnotic effects of ethanol and may potentially play a wider role in the differential ethanol responses observed between adolescents and adults.

    Acute septic arthritis in a native joint may require more than one surgical debridement to eradicate the infection. Our objectives were to determine the prevalence of failure of a single surgical debridement for acute septic arthritis, to identify risk factors for failure of a single debridement, and to develop a prognostic probability algorithm to predict failure of a single surgical debridement for acute septic arthritis in adults. We collected initial laboratory and medical comorbidity data of 128 adults (132 native joints) with acute septic arthritis who underwent at least one surgical debridement at our institution between 2000 and 2011. Univariate and logistic regression analyses were used to identify potential risk factors for failure of a single surgical debridement. Stepwise variable selection was used to develop a prediction model and identify probabilities of failure of a single surgical debridement. Of the 128 patients (132 affected joints) who underwent surgical debridement for acute septic arthritis, forty-nine (38%) of the patients (fifty joints) experienced failure of a single debridement and required at least two debridements (range, two to four debridements). Staphylococcus aureus was the most common bacterial isolate (in sixty, or 45%, of the 132 joints). Logistic regression analysis identified five independent clinical predictors for failure of a single surgical debridement: a history of inflammatory arthropathy (odds ratio [OR], 7.3; 95% confidence interval [CI], 2.4 to 22.6; p 85.0 x 10(9) cells/L (OR, 4.7; 95% CI, 1.8 to 17.7; p = 0.002), S. aureus as the bacterial isolate (OR, 4.6; 95% CI, 1.8 to 11.9; p = 0.002), and a history of diabetes (OR, 2.6; 95% CI, 1.1 to 6.2; p = 0.04). Most (62%) of the septic joints were managed effectively with a single surgical debridement. Adults with a history of inflammatory arthropathy, involvement of a large joint, a synovial-fluid nucleated cell count of >85.0 x 10(9) cells/L, an infection with S. aureus

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

    The prognosis, in the long term, of adolescents and young adults with acute de novo lymphoblastic leukemia, treated with a pediatric type protocol. To analyze the efficacy and tolerability of a chemotherapy regimen of pediatric type on patients 15-35 years old with de novo acute lymphoblastic leukemia, Ph(-). A retrospective study of patients received from 2001 to 2013, without initial infiltration of the central nervous system. They received the regimen called LALÍN. Terminal goals: frequency of initial remission, probability of survival free of leukemia and event-free survival for five years. We included 101 patients; there were 29 relapses and 19 deaths. There was initial remission in 97% of the cases; survival free of leukemia of 0.58 and event-free survival 0.44. No difference in patients aged 16-21 years vs. 22-35 (p > 0.55). Negative prognostic factors: abnormal karyotypes, except hyperdiploids (p = 0.001); > 5% of blasts, on 14 day induction (p = 0. 0001); delay in the punctuality of the courses of the chemotherapy regimen (p = 0.0001). A pediatric type regimen is applicable to patients aged from 16 to 35 years with acute lymphoblastic leukemia, without greater toxicity and a best survival free of leukemia. The count of > 5% of blasts and the delay in the execution of the stages of the chemotherapy regimen are the stronger negative prognostic factors.

    Full Text Available OBJECTIVE - To evaluate the cardiac abnormalities and their evolution during the course of the acquired immunodeficiency syndrome, as well as to correlate clinical and pathological data. METHODS - Twenty-one patients, admitted to the hospital with the diagnosis of acquired immunodeficiency syndrome, were prospectively studied and followed until their death. Age ranged from 19 to 42 years (17 males. ECG and echocardiogram were also obtained every six months. After death, macro- and microscopic examinations were also performed. RESULTS - The most frequent causes of referral to the hospital were: diarrhea or repeated pneumonias, tuberculosis, toxoplasmosis or Kaposi sarcoma. The most frequent findings were acute or chronic pericarditis (42% and dilated cardiomyopathy (19%. Four patients died of cardiac problems: infective endocarditis, pericarditis with pericardial effusion, bacterial myocarditis and infection by Toxoplasma gondii. CONCLUSION - Severe cardiac abnormalities were the cause of death in some patients. In the majority of the patients, a good correlation existed between clinical and anatomical-pathological data. Cardiac evaluation was important to detect early manifestations and treat them accordingly, even in asymptomatic patients.

    Full Text Available Abstract Background The physiological and biochemical responses to acute hypoxia have not been fully characterized in neonates. Fatty acids and lipids play an important role in most aspects of cardiac function. Methods We performed comprehensive lipid profiling analysis to survey the changes that occur in heart tissue and plasma of neonatal and young adult rats exposed to hypoxia for 2 h, and following 2 h of recovery from hypoxia. Results Cardiac and plasma concentrations of short-chain acylcarnitines, and most plasma long-chain fatty acids, were decreased in hypoxic neonates. Following recovery from hypoxia, concentrations of propionylcarnitine, palmitoylcarnitine, stearoylcarnitine were increased in neonatal hearts, while oleylcarnitine and linoleylcarnitine concentrations were increased in neonatal plasma. The concentrations of long-chain fatty acids and long-chain acylcarnitines were increased in the hearts and plasma of hypoxic young adult rats; these metabolites returned to baseline values following recovery from hypoxia. Conclusion There are differential effects of acute hypoxia on cardiac and plasma lipid profiles with maturation from the neonate to the young adult rat. Changes to neonatal cardiac and plasma lipid profiles during hypoxia likely allowed for greater metabolic and physiologic flexibility and increased chances for survival. Persistent alterations in the neonatal cardiac lipid profile following recovery from hypoxia may play a role in the development of rhythm disturbances.

    2015-12-15

    Symptomatic calcific discitis has been reported in the paediatric population but is a rare entity in adults with only eight cases reported in the English literature. We present a case of adult calcific discitis presenting with acute onset back pain. Radiographs and CT demonstrated central T11-T12 disc calcification with diffuse marrow oedema on subsequent MRI. The patient was referred to our spinal oncology unit due to the extensive marrow oedema as a possible underlying primary bone tumour. Review of the CT confirmed an end-plate defect with herniated calcific nucleus pulposus with no underlying bone lesion. Features were in keeping with acute calcific discitis. The patient was treated symptomatically and made an uneventful recovery. We discuss the characteristic imaging features seen on radiograph, CT and MRI and review the current literature. Calcific discitis is a self-limiting pathology requiring symptomatic management only. Radiologists need to be aware of this rare entity as it can occur in adults and may be mistaken for a more sinister pathology such as infective discitis or a bone tumour and lead to further unnecessary imaging or invasive procedures.

    Full Text Available Abstract Background For older adults, hospitalization frequently results in deterioration of mobility and function. Nevertheless, there are little data about how older adults exercise in the hospital and definitive studies are not yet available to determine what type of physical activity will prevent hospital related decline. Strengthening exercise may prevent deconditioning and Pilates exercise, which focuses on proper body mechanics and posture, may promote safety. Methods A hospital-based resistance exercise program, which incorporates principles of resistance training and Pilates exercise, was developed and administered to intervention subjects to determine whether acutely-ill older patients can perform resistance exercise while in the hospital. Exercises were designed to be reproducible and easily performed in bed. The primary outcome measures were adherence and participation. Results Thirty-nine ill patients, recently admitted to an acute care hospital, who were over age 70 [mean age of 82.0 (SD= 7.3] and ambulatory prior to admission, were randomized to the resistance exercise group (19 or passive range of motion (ROM group (20. For the resistance exercise group, participation was 71% (p = 0.004 and adherence was 63% (p = 0.020. Participation and adherence for ROM exercises was 96% and 95%, respectively. Conclusion Using a standardized and simple exercise regimen, selected, ill, older adults in the hospital are able to comply with resistance exercise. Further studies are needed to determine if resistance exercise can prevent or treat hospital-related deterioration in mobility and function.

    Objective Several lines of evidence implicate gray matter abnormalities in the prefrontal cortex and anterior cingulate cortex in patients with bipolar disorder. Findings however, have been largely inconsistent across studies. Differences in patients’ medication status or mood state, or the application of traditional volumetric methods that are insensitive to subtle neuroanatomic differences may have contributed to these inconsistent findings. Given this, we used magnetic resonance imaging (MRI) in conjunction with cortical pattern matching methods to assess cortical thickness abnormalities in euthymic bipolar subjects who were not treated with lithium. Method Sixty-five subjects, including 34 lithium-free euthymic subjects with bipolar (type I) disorder and 31 healthy subjects were scanned using magnetic resonance imaging (MRI). Data were processed to measure cortical gray matter thickness. Cortical pattern matching methods associated homologous brain regions across subjects. Spatially normalized thickness maps were analyzed to assess illness effects and associations with clinical variables. Results Relative to healthy subjects, euthymic bipolar I subjects had significantly thinner gray matter in bilateral prefrontal cortex (Brodmann Areas 11, 10, 8 and 44) and left anterior cingulate cortex (Brodmann Areas 24/32). Additionally, thinning in these regions was more pronounced in patients with a history of psychosis. No areas of thicker cortex were detected in bipolar subjects versus healthy subjects. Conclusions Using a technique that is highly sensitive to subtle neuroanatomic differences, significant regional cortical thinning was found in euthymic subjects with bipolar disorder. Clinical implications are discussed. PMID:21285139

    Full Text Available Abstract Background ZAP70 gene expression is associated with poor prognosis in B-cell lymphoproliferative disorders especially chronic lymphocytic leukaemia (CLL but its role in adult B-ALL has not been established. On diagnostic samples from 76 patients with adult ALL (65 with B-ALL and 11 with T-ALL ZAP70 mRNA expression levels were studied by real time-quantitative PCR (RT-qPCR analysis. Findings A broad distribution of ZAP70 expression was observed in ALL, ranging from 0.002 to 5.3 fold that of the ZAP70 positive Jurkat reference cell line. No association was observed between expression levels and the presence of specific cytogenetic abnormalities. Five cases, including one case of T-ALL, had ZAP70 expression above the level of the Jurkat reference cell line. Conclusions Our results confirm the frequent expression of ZAP70 in adult ALL. Limited comparisons made did highlight poor-risk patients with high ZAP70 expression, but due to lack of clinical information on patient samples we were unable to directly assess the impact on disease prognosis. ZAP-70 may be an important laboratory assay in adult ALL and further studies are warranted to study a potential correlation with cytogenetic and other genetic markers.

    The intense intrathecal inflammation observed in acute bacterial meningitis (ABM) is associated with pronounced changes in cerebral blood flow (CBF) and metabolism. In seven substudies, CBF and metabolism were measured in adults with ABM as well as healthy volunteers during various interventions....... Global and regional CBF was measured by transcranial Doppler ultrasonography, single-photon emission computed tomography, and the Kety-Schmidt method. Cerebral metabolism and net flux were measured by the Fick principle. Interventions included intravenous norepinephrine infusion, acute hyperventilation......, propofol infusion, and mannitol infusion. Global CBF in patients was lower than that of controls; cerebral oxygen extraction and metabolism was lower in patients than in controls. Regional CBF was more heterogeneous in patients than in controls. Norepinephrine infusion increased mean arterial pressure...

Eight (88.9% patients, including two Philadelphia chromosome-positive ALL patients, achieved a complete remission. Furthermore, the evaluable patients have benefited from allo-HSCT after response to this reinduction treatment.

    Full Text Available Background. Tocilizumab, a monoclonal humanized anti-IL-6 receptor antibody, is used in treatment of refractory adult onset Still’s disease (AOSD. Mild to moderate liver enzyme elevation is a well-known side effect, but severe liver injury has only been reported in 3 cases in the literature. Case. A young female suffering from corticoid and methotrexate refractory AOSD was treated by tocilizumab. After 19 months of consecutive treatment, she developed acute severe liver injury. Liver biopsy showed extensive hepatocellular necrosis with ballooned hepatocytes, highly suggestive of drug-induced liver injury. No other relevant drug exposure beside tocilizumab was recorded. She recovered totally after treatment discontinuation and an initial 3-day course of intravenous N-acetylcysteine with normalization of liver function tests after 6 weeks. Conclusion. Acute severe hepatitis can be associated with tocilizumab as documented in this case. Careful monitoring of liver function tests is warranted during tocilizumab treatment.

    No studies to date have systematically investigated insomnia symptoms among adults with sickle cell disease (SCD). The purpose of this study was to (1) describe the prevalence of insomnia symptoms and (2) identify biopsychosocial predictors in community-dwelling adults with SCD. Cross-sectional analysis of baseline data from 263 African American adults with SCD (aged 18 years or older). Measures included the Insomnia Severity Index (ISI), Center for Epidemiologic Studies in Depression scale, Urban Life Stress Scale, Brief Pain Inventory, and a chronic pain item. SCD genotype was extracted from the medical record. A slight majority (55%) of the sample reported clinically significant insomnia symptomatology (ISI ≥ 10), which suggests that insomnia symptoms are prevalent among community-dwelling African American adults with SCD. While insomnia symptoms were associated with a number of biopsychosocial characteristics, depressive symptoms and acute pain were the only independent predictors. Given the high number of participants reporting clinically significant insomnia symptoms, nurses should screen for insomnia symptoms and explore interventions to promote better sleep among adults with SCD, with an emphasis on recommending treatment for pain and depression. In addition, current pain and depression interventions in this population could add insomnia measures and assess the effect of the intervention on insomnia symptomatology as a secondary outcome.

    Full Text Available OBJECTIVE: To determine the prevalence of hyperglycemia during induction therapy in adult patients with acute leukemia and its effect on complicated infections and mortality during the first 30 days of treatment. METHODS: An analysis was performed in a retrospective cohort of 280 adult patients aged 18 to 60 years with previously untreated acute leukemia who received induction chemotherapy from January 2000 to December 2009 at the Hemocentro de Pernambuco (HEMOPE, Brazil. Hyperglycemia was defined as the finding of at least one fasting glucose measurement > 100 mg/dL observed one week prior to induction therapy until 30 days after. The association between hyperglycemia and complicated infections, mortality and complete remission was evaluated using the Chi-square or Fisher's exact tests by the Statistical Package for Social Sciences (SPSS in the R software package version 2.9.0. RESULTS: One hundred and eighty-eight patients (67.1% presented hyperglycemia at some moment during induction therapy. Eighty-two patients (29.3% developed complicated infections. Infection-related mortality during the neutropenia period was 20.7% (58 patients. Mortality from other causes during the first 30 days after induction was 2.8%. Hyperglycemia increased the risk of complicated infections (OR 3.97; 95% confidence interval: 2.08 - 7.57; p-value < 0.001 and death (OR 3.55; 95% confidence interval: 1.77-7.12; p-value < 0.001 but did not increase the risk of fungal infections or decrease the probability of achieving complete remission. CONCLUSION: This study demonstrates an association between the presence of hyperglycemia and the development of complicated infections and death in adult patients during induction therapy for acute leukemia.

    In the setting of primary prevention, most implantable cardiac defibrillators (ICD) are implanted more than 6 months after acute myocardial infarction (AMI). Abnormal heart rate turbulence (HRT) and T-wave alternans (TWA) are predictors of long-term sudden cardiac death (SCD). We intended to assess the predictive value of HRT and TWA for early post-AMI SCD and life-threatening ventricular arrhythmias (VA). One hundred ninety-nine consecutive patients with AMI were prospectively included (age 61.7 years, LV ejection fraction 45%). One hundred eighty-three patients (92%) underwent percutaneous coronary intervention. We assessed HRT using turbulence slope (TS), turbulence onset (TO), and TWA on channels 1 and 2 (TWA1 and TWA2) using the modified moving average method. Predictive performance for SCD/VA was assessed by area under the receiver operating curve characteristic (ROC-AUC). Within 6 months after AMI, 2 patients (1%) developed life-threatening VA and 3 (1.5%) experienced SCD. TO and TWA1 had poor ROC-AUC (both 0.64) whereas TS and TWA2 failed to show any predictive performance (ROC-AUC 0.48 and 0.57, respectively). When combining TO and TWA1, ROC-AUC increased to 0.80. Importantly, when considering the subset of patients with a LV ejection fraction ≤40%, the combined variable of TO and TWA1 remained strongly predictive of a short-term event (ROC-AUC 0.86). Combined assessment of HRT and TWA showed a high predictive performance for SCD or life-threatening VA within 6 months after AMI. This combined Holter ECG index could be useful to identify high-risk patients who might benefit from early ICD implantation. ©2013 Wiley Periodicals, Inc.

  6. RBP2 Promotes Adult Acute Lymphoblastic Leukemia by Upregulating BCL2.

    Directory of Open Access Journals (Sweden)

    Xiaoming Wang

    Full Text Available Despite recent increases in the cure rate of acute lymphoblastic leukemia (ALL, adult ALL remains a high-risk disease that exhibits a high relapse rate. In this study, we found that the histone demethylase retinoblastoma binding protein-2 (RBP2 was overexpressed in both on-going and relapse cases of adult ALL, which revealed that RBP2 overexpression was not only involved in the pathogenesis of ALL but that its overexpression might also be related to relapse of the disease. RBP2 knockdown induced apoptosis and attenuated leukemic cell viability. Our results demonstrated that BCL2 is a novel target of RBP2 and supported the notion of RBP2 being a regulator of BCL2 expression via directly binding to its promoter. As the role of RBP2 in regulating apoptosis was confirmed, RBP2 overexpression and activation of BCL2 might play important roles in ALL development and progression.

    Dental pain can have a considerable detrimental effect on an individual's quality of life. Symptomatic apical periodontitis and acute apical abscess are common causes of dental pain and arise from an inflamed or necrotic dental pulp, or infection of the pulpless root canal system. Clinical guidelines recommend that the first-line treatment for teeth with symptomatic apical periodontitis or an acute apical abscess should be removal of the source of inflammation or infection by local, operative measures, and that systemic antibiotics are currently only recommended for situations where there is evidence of spreading infection (cellulitis, lymph node involvement, diffuse swelling) or systemic involvement (fever, malaise). Despite this, there is evidence that dentists continue to prescribe antibiotics for these conditions. There is concern that this could contribute to the development of antibiotic-resistant bacterial colonies both within the individual and within the community as a whole. To evaluate the effects of systemic antibiotics provided with or without surgical intervention (such as extraction, incision and drainage of a swelling or endodontic treatment), with or without analgesics, for symptomatic apical periodontitis or acute apical abscess in adults. We searched the following electronic databases: Cochrane Oral Health Group's Trials Register (to 1 October 2013); Cochrane Central Register of Controlled Trials (The Cochrane Library 2013, Issue 9); MEDLINE via OVID (1946 to 1 October 2013); EMBASE via OVID (1980 to 1 October 2013) and CINAHL via EBSCO (1980 to 1 October 2013). We searched the World Health Organization (WHO) International Trials Registry Platform and the US National Institutes of Health Trials Registry (ClinicalTrials.gov) on 1 October 2013 to identify ongoing trials. We searched for grey literature using OpenGrey (to 1 October 2013) and ZETOC Conference Proceedings (1993 to 1 October 2013). We placed no restrictions on the language or date of

    To determine how often hospitalized older adults principally diagnosed with pneumonia, chronic obstructive pulmonary disease (COPD), or heart failure (HF) are concurrently treated for two or more of these acute cardiopulmonary conditions. Retrospective cohort study. 368 U.S. hospitals in the Premier research database. Individuals aged 65 and older principally hospitalized with pneumonia, COPD, or HF in 2009 or 2010. Proportion of diagnosed episodes of pneumonia, COPD, or HF concurrently treated for two or more of these acute cardiopulmonary conditions during the first 2 hospital days. Of 91,709 diagnosed pneumonia hospitalizations, 32% received treatment for two or more acute cardiopulmonary conditions (18% for HF, 18% for COPD, 4% for both). Of 41,052 diagnosed COPD hospitalizations, 19% received treatment for two or more acute cardiopulmonary conditions (all of which involved additional HF treatment). Of 118,061 diagnosed HF hospitalizations, 38% received treatment for two or more acute cardiopulmonary conditions (34% for pneumonia, 9% for COPD, 5% for both). Hospitalized older adults diagnosed with pneumonia, COPD, or HF are frequently treated for two or more acute cardiopulmonary conditions, suggesting that clinical syndromes often fall between traditional diagnostic categories. Research is needed to evaluate the risks and benefits of real-world treatment for the many older adults whose presentations elicit diagnostic uncertainty or concern about coexisting acute conditions. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    Most adults with bacterial meningitis and meningococcal septicaemia present to junior doctors who have limited experience of these conditions. In contrast to paediatric practice, data from industrialized countries with regard to current hospital management practice are lacking. To examine whether current practice meets recommended standards in hospital management of community-acquired bacterial meningitis and meningococcal septicaemia among adults. National audit of medical records. We conducted a survey of all patients with acute bacterial meningitis and meningococcal septicaemia admitted to 18 randomly selected acute hospitals in England and Wales between 1 January 2000 and 31 December 2001. All stages of care, including pre-hospital management, initial hospital assessment, record keeping, and ongoing hospital and public health management, were assessed. We identified 212 cases of bacterial meningitis and meningococcal septicaemia; 190 cases remained in the final analysis. Clinical record keeping did not meet acceptable standards in 33% of cases. Parenteral antibiotics were given within 1 h of hospital arrival in 56% of cases, increasing to 79% among those with an initial differential diagnosis that included bacterial meningitis or meningococcal septicaemia. A full severity of illness assessment was made in 27%. The quality of clinical practice varied widely between hospitals. This was most pronounced in the timeliness of consultant review (p < 0.0005). The quality of adult clinical practice for bacterial meningitis and meningococcal septicaemia needs improvement. This study provides a tool for developing targeted interventions to improve quality of care and outcome among adults with life-threatening infections, both in the UK and in other countries.

    The loss of an only child is a negative life event and may potentially increase the risk of psychiatric disorders. However, the psychological consequences of the loss of an only child and the associated neural mechanisms remain largely unexplored. Degree centrality (DC), derived from resting-state functional magnetic resonance imaging (fMRI), was used to examine network communication in 22 older adults who lost their only child and 23 matched controls. The older adults who lost their only child exhibited an ineffective coping style. They also showed decreased distant and local DC in the precuneus and left inferior parietal lobule and decreased distant DC in the bilateral dorsolateral prefrontal cortex (DLPFC). Furthermore, the decreased local and distant DC of these regions and the decreased DLPFC-precuneus connectivity strength were negatively correlated with negative coping scores in the loss group but not in the controls. Overall, the results suggested a model that the impaired neural network communication of brain hubs within the default mode network (DMN) and central executive network (CEN) were associated with a negative coping style in older adults who lost their only child. The decreased connectivity of the hubs can be identified as a neural risk factor that is related to future psychopathology. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available BACKGROUND: The prevalence of chronic kidney disease (CKD has increased and will continue to rise worldwide. However, data regarding the prevalence of CKD in a rural area of China are limited. We therefore investigated the prevalence and associated risk factors of impaired renal function and urinary abnormalities in an adult rural population in southern China. METHODS: Between December 2006 and January 2007, residents older than 20 years from four villages in Zhuhai city were randomly selected using a stratified, multistage sampling technique. All participants were interviewed and tested for hematuria, albuminuria and estimated glomerular filtration rate (eGFR. The associations between age, gender, diabetes mellitus, hypertension, hyperuricemia, education level and indicators of renal damage were examined. RESULTS: Overall, 1,214 subjects were enrolled in this study. After adjustment for age and gender, the prevalence of albuminuria was 7.1% (95% CI: 4.5, 8.1, reduced eGFR was 2.6% (95% CI: 1.7%, 3.3%, and hematuria was 4.6% (95% CI: 3.3%, 6.0%. Approximately 13.6% (95% CI: 12.0%, 15.1% of the patients had at least one indicator of renal damage, but only 8.3% were previously aware. Age, diabetes, hyperlipidemia, hypertension, hyperuricemia, use of nephrotoxic medications, coronary heart disease and history of CKD were independently associated with impaired renal function and urinary abnormalities. Additionally, age, diabetes, and hypertension were independently associated with albuminuria. Age, hypertension, hyperuricemia, central obesity, and coronary heart disease were independently associated with reduced renal function. CONCLUSIONS: The high prevalence and low awareness of impaired renal function and urinary abnormalities in this population illustrates the urgent need to implement a CKD prevention program in the rural areas of southern China.

However, for those in the adolescent and young adult (AYA age-group of 15–30 years with ALL, there has not been the same degree of improvement. Historically, pediatric and adult providers have utilized different treatment approaches based on clinical trials. However, studies that have compared the outcome of AYA patients with ALL treated on pediatric or adult clinical trials have generally shown substantially better outcomes for this patient population treated with the pediatric trials. Additionally, hematopoietic stem cell transplantation has been considered as part of intensified therapy for AYA patients with ALL. Herein, we review the outcomes with chemotherapy alone and with hematopoietic stem cell transplantation, and explore the challenges faced in determining the ideal therapy for the AYA population of patients.

    Full Text Available Saad Sirop Kenderian, Mark R Litzow Division of Hematology, Department of Internal Medicine, Mayo Clinic, Rochester, MN, USA Abstract: Acute lymphoblastic leukemia (ALL in adolescents and young adults (AYA represents a unique and challenging disease entity. Despite the recent improvement of survival in this population over the last decade, it is still lagging behind the excellent cure rates obtained in pediatric ALL. This special population of AYA receives care from pediatric as well as adult hematologists and can be treated on pediatric or adult protocols. There is a substantial difference in disease biology, response to chemotherapy, and allogeneic stem cell transplantation between pediatric and AYA patients. This review discusses current controversies in the management of AYA, outcomes following treatment with pediatric and adult protocols, and the role of allogeneic stem cell transplantation. It focuses on the unique clinical, biological, and socioeconomic characteristics of this population that might partly explain the inferior outcomes. This review also explores recent advances in genomic profiling and emerging treatments in ALL.

    Full Text Available Objectives. Acute acquired comitant esotropia (AACE can be a diagnostic challenge for ophthalmologists and neurologists because of its association with neurological pathologies. Our study describes a series of adult patients with AACE of undetermined etiology. Methods. Data on the clinical findings of patients presented with AACE of undetermined etiology with a minimum follow-up of 1 year were retrieved from the medical records and the results analyzed. Results. A series of 9 esotropia cases (age range: 20–43 years was reviewed. All patients had full duction and versions, without an A-pattern or V-pattern. All patients had esotropia for distance and near. Neurological evaluation in all cases was normal. Among patients, 3 were treated with prisms, 4 were treated with strabismus surgery, and 1 was treated with botulinum toxin injections; 1 patient declined treatment. In treated patients posttreatment sensory testing indicated restoration of binocularity that remained stable throughout follow-up of 1–9 years. The patient that declined treatment had binocular function with base-out prisms. Conclusion. Acute onset esotropia may be seen without a neurological pathology in adults. Good motor and sensory outcomes can be achieved in these patients with AACE of undetermined etiology via surgical and nonsurgical methods.

    PURPOSE: This study analyzed whether prehospital or in-hospital delay was the more significant influence on perforation rates for acute appendicitis and whether any clinical feature designated patients requiring higher surgical priority. METHODS: A retrospective analysis was conducted over one year at a tertiary referral hospital without a dedicated emergency surgical theater. Admission notes, theater logbook, and the Hospital Inpatient Enquiry system were reviewed to identify the characteristics and clinical course of patients aged greater than 16 years who were operated upon for histologically confirmed acute appendicitis. RESULTS: One hundred and fifteen patients were studied. The overall perforation rate was 17 percent. The mean duration of symptoms prior to hospital presentation was 38.1 hours with the mean in-hospital waiting time prior to operation being 23.4 hours. Although body temperature on presentation was significantly greater in patients found to have perforated appendicitis (P < 0.05), only patient heart rate at presentation and overall duration of symptoms, but not in-hospital waiting time, independently predicted perforation by stepwise linear regression modeling. CONCLUSION: In-hospital delay was not an independent predictor of perforation in adults with acute appendicitis although delays may contribute if patients are left to wait unduly. Tachycardia at presentation may be a quantifiable feature of those more likely to have perforation and who should be given higher surgical priority.

    Nifuroxazide is well known and often used anti-diarrhoeal medicine which has been pushed back from routine practice in recent years and often replaced with probiotics. Even probiotics are accepted and placed in some therapeutic guidelines for diarrhoea treatment, there are no enough evidence for its effectiveness and no comparative efficacy data with nifuroxazide in treatment of acute diarrhea. In open, prospective observational study, the efficacy and safety of nifuroxazide were compared with a probiotic containing lactic acid bacteria in the treatment of acute diarrhoea. A total number of 169 adult patients were included in this study, who administered nifuroxazide in the dose of 200 mg/4 times a day, while they took preparation containing lactic acid bacteria (1,2 x 10 7 live lyophilised lactic-acid bacteria) three times a day for three days. Mean time to last unformed stool (TLUS) in a group which was treated with nifuroxazide was two days, while it took five days for the stool normalisation in the group using probiotic (p=0.0001). Orally administered nifuroxazide has demonstrated better efficiency as compared to probiotic in treating acute diarrhoea, and both medicines have shown the same safety and tolerance in this study.

Suspected dengue, especially in children in Nicaragua's heavily-urbanized capital of Managua, has been well documented, but unsuspected dengue among children and adults with undifferentitated fever has not.To prospectively study dengue in semi-urban and rural western Nicaragua, we obtained epidemiologic and clinical data as well as acute and convalescent sera (2 to 4 weeks after onset of illness from a convenience sample (enrollment Monday to Saturday daytime to early evening of consecutively enrolled patients (n = 740 aged ≥ 1 years presenting with acute febrile illness. We tested paired sera for dengue IgG and IgM and serotyped dengue virus using reverse transcriptase-PCR. Among 740 febrile patients enrolled, 90% had paired sera. We found 470 (63.5% were seropositive for dengue at enrollment. The dengue seroprevalance increased with age and reached >90% in people over the age of 20 years. We identified acute dengue (serotypes 1 and 2 in 38 (5.1% patients. Only 8.1% (3/37 of confirmed cases were suspected clinically.Dengue is an important and largely unrecognized cause of fever in rural western Nicaragua. Since Zika virus is transmitted by the same vector and has been associated with severe congenital infections, the population we studied is at particular risk for being devastated by the Zika epidemic that has now reached Central America.

    To determine the efficacy and safety of different antipsychotic drugs in the management of patients diagnosed with schizophrenia in the acute phase. To formulate evidence-based recommendations on the antipsychotic (AP) drug management strategies for the treatment of the adult diagnosed with schizophrenia in the acute phase. Clinical practice guidelines were prepared, using the guidelines of the Methodology Guide of the Ministry of Health and Social Protection, in order to identify, synthesise, and evaluate the evidence and formulate recommendations as regards the management and follow-up of adult patients diagnosed with schizophrenia. The evidence of the NICE 82 guideline was adopted and updated, which answered the question on the management of the acute phase of adults with a diagnosis of schizophrenia. The evidence and its level were presented to the Guideline Development Group (GDG) in order to formulate recommendations following the methodology proposed by the GRADE approach. Clozapine, olanzapine, risperidone, ziprasidone, amisulpride, paliperidone, haloperidol, quetiapine, and aripiprazole were more effective than placebo for the majority of psychotic symptoms and the abandonment of treatment, but asenapine was not. Paliperidone, risperidone, quetiapine, clozapine, and olanzapine showed significant increases in weight compared to placebo. Haloperidol, risperidone, ziprasidone, and paliperidone had a higher risk of extrapyramidal symptoms than placebo. There was a significant risk of sedation or drowsiness with, risperidone, haloperidol, ziprasidone, quetiapine, olanzapine, and clozapine in the comparisons with placebo. Of the results of the comparisons between AP, it was shown that clozapine and paliperidone had a clinically significant effect compared to haloperidol and quetiapine, respectively. Olanzapine and risperidone had a lower risk of abandoning the treatment in general, and due to adverse reactions in two comparisons of each one, haloperidol was the

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

Data obtained in the period of shigellosis high incidence level have shown that there has been no significant difference in clinical scores (including colitis frequency between cases positive only for rotavirus antigen and those positive both for rotavirus antigen and Shigella spp. culture. That let suspect that acute diarrhea had been likely to be caused by association of rotavirus with any bacterial agent undetected by the methods used.

So, the PCR method might be quite useful to broaden the spectrum of detected enteropathogens in adult acute diarrhea cases especially in those with colitis syndrome available.

    There is growing evidence of sex differences in the chronic effect of aerobic exercise on endothelial function (flow-mediated dilation; FMD) in older adults, but whether there are sex differences also in the acute effect of aerobic exercise on FMD in older adults is unknown. The purpose of this study was to test the hypothesis that sex modulates the FMD response to acute aerobic exercise in older adults. Thirteen older men and fifteen postmenopausal women (67±1 vs. 65±2years, means±SE, P=0.6), non-smokers, free of major clinical disease, participated in this randomized crossover study. Brachial artery FMD was measured: 1) prior to exercise; 2) 20min after a single bout of high-intensity interval training (HIIT; 40min; 4×4 intervals 90% peak heart rate (HRpeak)), moderate-intensity continuous training (MICT; 47min 70% HRpeak) and low-intensity continuous training (LICT; 47min 50% HRpeak) on treadmill; and 3) following 60-min recovery from exercise. In older men, FMD was attenuated by 45% following HIIT (5.95±0.85 vs. 3.27±0.52%, P=0.003) and by 37% following MICT (5.97±0.87 vs. 3.73±0.47%, P=0.03; P=0.9 for FMD response to HIIT vs. MICT) and was normalized following 60-min recovery (P=0.99). In postmenopausal women, FMD did not significantly change in response to HIIT (4.93±0.55 vs. 6.31±0.57%, P=0.14) and MICT (5.32±0.62 vs. 5.60±0.68%, P=0.99). In response to LICT, FMD did not change in postmenopausal women nor older men (5.21±0.64 vs. 6.02±0.73%, P=0.7 and 5.70±0.80 vs. 5.55±0.67%, P=0.99). In conclusion, sex and exercise intensity influence the FMD response to acute aerobic exercise in older adults. Copyright © 2017 Elsevier Inc. All rights reserved.

    Chronic Hepatitis C virus (HCV) infection may cause kidney injury, particularly in the setting of cryoglobulinemia or cirrhosis; however, few studies have evaluated the epidemiology of acute kidney injury in patients with HCV. We aimed to describe national temporal trends of incidence and impact of severe AKI requiring renal replacement (“dialysis-requiring AKI”) in hospitalized adults with HCV. We extracted our study cohort from the Nationwide Inpatient Sample of the Healthcare Cost and Utilization Project using data from 2004–2012. We defined HCV and dialysis-requiring acute kidney injury based on previously validated ICD-9-CM codes. We analyzed temporal changes in the proportion of hospitalizations complicated by dialysis-requiring AKI and utilized survey multivariable logistic regression models to estimate its impact on in-hospital mortality. We identified a total of 4,603,718 adult hospitalizations with an associated diagnosis of HCV from 2004–2012, of which 51,434 (1.12%) were complicated by dialysis-requiring acute kidney injury. The proportion of hospitalizations complicated by dialysis-requiring acute kidney injury increased significantly from 0.86% in 2004 to 1.28% in 2012. In-hospital mortality was significantly higher in hospitalizations complicated by dialysis-requiring acute kidney injury vs. those without (27.38% vs. 2.95%; adjusted odds ratio 2.09, 95% Confidence Interval 1.74–2.51). The proportion of HCV hospitalizations complicated by dialysis-requiring acute kidney injury increased significantly between 2004–2012. Similar to observations in the general population, dialysis-requiring acute kidney injury was associated with a two-fold increase in odds of in-hospital mortality in adults with HCV. These results highlight the burden of acute kidney injury in hospitalized adults with HCV infection. PMID:26189719

    Hospitals are standard of care for acute illness, but hospitals can be unsafe, uncomfortable, and expensive. Providing substitutive hospital-level care in a patient's home potentially reduces cost while maintaining or improving quality, safety, and patient experience, although evidence from randomized controlled trials in the US is lacking. Determine if home hospital care reduces cost while maintaining quality, safety, and patient experience. Randomized controlled trial. Adults admitted via the emergency department with any infection or exacerbation of heart failure, chronic obstructive pulmonary disease, or asthma. Home hospital care, including nurse and physician home visits, intravenous medications, continuous monitoring, video communication, and point-of-care testing. Primary outcome was direct cost of the acute care episode. Secondary outcomes included utilization, 30-day cost, physical activity, and patient experience. Nine patients were randomized to home, 11 to usual care. Median direct cost of the acute care episode for home patients was 52% (IQR, 28%; p = 0.05) lower than for control patients. During the care episode, home patients had fewer laboratory orders (median per admission: 6 vs. 19; p Home patients were more physically active (median minutes, 209 vs. 78; p home patients, one occurred in control patients. Median direct cost for the acute care plus 30-day post-discharge period for home patients was 67% (IQR, 77%; p home-care services (22% vs. 55%; p = 0.08) and fewer readmissions (11% vs. 36%; p = 0.32). Patient experience was similar in both groups. The use of substitutive home-hospitalization compared to in-hospital usual care reduced cost and utilization and improved physical activity. No significant differences in quality, safety, and patient experience were noted, with more definitive results awaiting a larger trial. Trial Registration NCT02864420.

    To explore the characteristics of and interactions between clinicians, patients and family members during management of the deteriorating adult patient in the emergency department. Previous research into family presence during resuscitation has identified many positive outcomes when families are included. However, over the last three decades the epidemiology of acute clinical deterioration has changed, with a decrease in in-hospital cardiac arrests and an increase in acute clinical deterioration. Despite the decrease in cardiac arrests, research related to family presence continues to focus on care during resuscitation rather than care during acute deterioration. Descriptive exploratory study using nonparticipatory observation. Five clinical deterioration episodes were observed within a 50-bed, urban, Australian emergency department. Field notes were taken using a semistructured tool to allow for thematic analysis. Presence, roles and engagement describe the interactions between clinicians, family members and patients while family are present during a patient's episode of deterioration. Presence was classified as no presence, physical presence and therapeutic presence. Clinicians and family members moved through primary, secondary and tertiary roles during patients' deterioration episode. Engagement was observed to be superficial or deep. There was a complex interplay between presence, roles and engagement with each influencing which form the other could take. Current practices of managing family during episodes of acute deterioration are complex and multifaceted. There is fluid interplay between presence, roles and engagement during a patient's episode of deterioration. This study will contribute to best practice, provide a strong foundation for clinician education and present opportunities for future research. © 2017 John Wiley & Sons Ltd.

    Purpose: Efficacy and acute toxicity of proton craniospinal irradiation (p-CSI) were compared with conventional photon CSI (x-CSI) for adults with medulloblastoma. Methods and Materials: Forty adult medulloblastoma patients treated with x-CSI (n=21) or p-CSI (n=19) at the University of Texas MD Anderson Cancer Center from 2003 to 2011 were retrospectively reviewed. Median CSI and total doses were 30.6 and 54 Gy, respectively. The median follow-up was 57 months (range 4-103) for x-CSI patients and 26 months (range 11-63) for p-CSI. Results: p-CSI patients lost less weight than x-CSI patients (1.2% vs 5.8%; P=.004), and less p-CSI patients had >5% weight loss compared with x-CSI (16% vs 64%; P=.004). p-CSI patients experienced less grade 2 nausea and vomiting compared with x-CSI (26% vs 71%; P=.004). Patients treated with x-CSI were more likely to have medical management of esophagitis than p-CSI patients (57% vs 5%, P<.001). p-CSI patients had a smaller reduction in peripheral white blood cells, hemoglobin, and platelets compared with x-CSI (white blood cells 46% vs 55%, P=.04; hemoglobin 88% vs 97%, P=.009; platelets 48% vs 65%, P=.05). Mean vertebral doses were significantly associated with reductions in blood counts. Conclusions: This report is the first analysis of clinical outcomes for adult medulloblastoma patients treated with p-CSI. Patients treated with p-CSI experienced less treatment-related morbidity including fewer acute gastrointestinal and hematologic toxicities

    Full Text Available BACKGROUND: Organotypic tissue culture of adult rodent retina with an acute gene transfer that enables the efficient introduction of variable transgenes would greatly facilitate studies into retinas of adult rodents as animal models. However, it has been a difficult challenge to culture adult rodent retina. The purpose of this present study was to develop organotypic tissue culture of adult rodent retina followed by particle-mediated acute gene transfer in vitro. METHODOLOGY/PRINCIPAL FINDINGS: We established an interphase organotypic tissue culture for adult rat retinas (>P35 of age which was optimized from that used for adult rabbit retinas. We implemented three optimizations: a greater volume of Ames' medium (>26 mL per retina, a higher speed (constant 55 rpm of agitation by rotary shaker, and a greater concentration (10% of horse serum in the medium. We also successfully applied this method to adult mouse retina (>P35 of age. The organotypic tissue culture allowed us to keep adult rodent retina morphologically and structurally intact for at least 4 days. However, mouse retinas showed less viability after 4-day culture. Electrophysiologically, ganglion cells in cultured rat retina were able to generate action potentials, but exhibited less reliable light responses. After transfection of EGFP plasmids by particle-mediated acute gene transfer, we observed EGFP-expressing retinal ganglion cells as early as 1 day of culture. We also introduced polarized-targeting fusion proteins such as PSD95-GFP and melanopsin-EYFP (hOPN4-EYFP into rat retinal ganglion cells. These fusion proteins were successfully transferred into appropriate locations on individual retinal neurons. CONCLUSIONS/SIGNIFICANCE: This organotypic culture method is largely applicable to rat retinas, but it can be also applied to mouse retinas with a caveat regarding cell viability. This method is quite flexible for use in acute gene transfection in adult rodent retina, replacing

    Our previous work demonstrated differential neurobehavioral effects of low-dose alcohol consumption on older and younger adults in a driving simulator. However, the ability to enhance or suppress a response in such context has yet to be examined. The current study contrasted older and younger drivers' responses to specific stimuli (i.e., relevant, irrelevant) in scenarios of differing complexity following low-dose acute alcohol administration. Healthy older (55-70) and younger (25-35) adults completed two driving scenarios (i.e., country and metropolis) both before and after consuming beverages targeted to reach peak BrACs of 0.00, 0.04, or 0.065%. Throughout the simulation, participants encountered relevant stimuli (e.g., pedestrians walking into the street) and irrelevant stimuli (e.g., pedestrians walking parallel). Peak deceleration, range of steering, and distance until brake application were assessed within a 450-ft window preceding each stimulus. Following low-dose alcohol consumption, older adults shifted from a strategy using both deceleration and steering to relying solely on deceleration in responding to relevant stimuli in the country. Older adults under both low and moderate alcohol conditions displayed an inability to withhold responses to irrelevant stimuli in the metropolis. These findings are consistent with our prior work showing differential effects of low-dose alcohol on older, relative to younger, adults. The interactive effects of age and alcohol, however, depend on stimulus type and environmental complexity. Continued investigation of neurobehavioral mechanisms in ecologically valid paradigms is necessary for understanding the implications of the combined impairing effects of alcohol and older age.

    Background The prevalence of type 2 diabetes mellitus is rapidly increasing, worldwide and also in Hungary. Timely diagnosis and early treatment could be aided by targeted screening. Recognizing this, the Hungarian Diabetes Association initiated a risk-stratified screening with the involvement of primary care physicians. Material/Methods In the first phase of screening, the FINDRISC questionnaire was completed, followed by an oral glucose tolerance test (OGTT) for those with a score of ≥12. Between September 1, 2010 and March 31, 2011, 70,432 non-diabetic adults, who visited their general practitioners for any reason, were involved in the screening. Of these, 68,476 questionnaires proved to be suitable for processing. Results From the questionnaires, 28,077 (41.0%) had a score of ≥12. A valid OGTT was performed in 22,846 cases; of this group 3,217 subjects (14.1%) had elevated fasting glucose levels, 5,663 (24.8%) had impaired glucose tolerance, and 1,750 (7.6%) had manifest, previously undiagnosed, diabetes mellitus. Overall, from the valid OGTT group, 46.5% subjects had some degree of glucose intolerance. Conclusions Based on the FINDRISC questionnaire, the risk-stratified screening for diabetes mellitus proved to be simple and cost-effective method for the early detection of carbohydrate metabolism disorders. Using this method, the prevalence rate of previously undiagnosed abnormal glucose tolerance was high in adult patients cared for by general practitioners in Hungary. PMID:23344680

    Tumor immune escape mechanism mediated by CD4+CD25+regulatory T cells (Tregs) is a key factor in the pathogenesis of acute myeloid leukemia (AML). IL-35, as a novel inhibitory cytokine, is produced by Tregs specially and regulates functions of Tregs in murine. However, IL-35 expression of Tregs in human is still disputed, and its role in AML is yet to be elucidated. In this study, we found that IL-35 was expressed highly in peripheral blood plasma of adult patients with AML and significantly correlated with the clinical stages of malignancy. Tregs-derived from adult AML patients produced IL-35 in a stimulation-dependent manner. IL-35 promoted AML blasts immune escape by expanding Tregs and inhibiting CD4+CD25-effector T cells (Teffs). Furthermore, IL-35 directly promoted the proliferation of AML blasts and reduced the apoptosis of AML blasts. Together, our study demonstrates that IL-35-derived from Tregs promotes the growth of adult AML blasts, suggesting that IL-35 has an important role in the pathogenesis of AML. © 2015 UICC.

    Adults with attention deficit hyperactivity disorder (ADHD) have difficulties processing affective prosody, and research evidence demonstrates the importance of brain serotonin (5-HT) in the neurobiology of ADHD. This study aimed to investigate whether diminished brain 5-HT synthesis, as achieved by acute tryptophan depletion (ATD), can impair the processing of affective prosody in adults with ADHD. Twenty male patients with ADHD and twenty male healthy controls received ATD and a tryptophan-balanced control condition on separate days in a double-blind within-subject repeated measures crossover design. In both conditions, the Tübingen Affect Battery was administered in which subjects had to name the affective prosody of sentences with neutral, congruent, or incongruent semantic content. Participants in the group of patients with ADHD perceived affective prosody less accurately than controls. Participants with ADHD showed compromised processing of sentences, committing more errors than healthy controls when identifying affect in instances of incongruent semantic content (P = 0.031). ATD did not contribute to this effect (all P > 0.5). The difficulties male adults with ADHD have in accurately processing affective prosody may result from impairments in their ability to inhibit unwanted stimuli and impulses. No clear evidence implicates 5-HT as a cause of these impairments. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  12. Fatal H1N1-Related Acute Necrotizing Encephalopathy in an Adult

    Full Text Available Acute necrotizing encephalopathy (ANE is a severe neurological complication of influenza infection, including H1N1 influenza. Many cases of ANE have been reported in the pediatric literature, but very few cases have been described in adults. The cause of ANE remains unknown—the influenza virus is not known to be neurotropic, and evidence of direct viral involvement of the central nervous system (CNS has not been demonstrated in the limited cases of ANE in which pathological specimens have been obtained. Here we report a fatal case of ANE from H1N1 influenza infection in an adult. Neuroimaging and postmortem analysis both showed widespread brain edema, necrosis, and hemorrhage, but molecular studies and postmortem pathology revealed no evidence of direct viral involvement of the CNS. This case of fatal ANE in an adult is consistent with the hypothesis generated from pediatric cases that the host immune response, and not direct viral invasion of the CNS, is responsible for pathogenesis of ANE.

    Most adults with sickle cell disease (SCD) receive care for their acute painful episodes in an emergency department (ED) setting. The purpose of this article is to describe the impact of opening a dedicated treatment center for adults with SCD [Sickle Cell Infusion Clinic (SCIC)] on patient outcomes and on hospital discharges for SCD. Descriptive data including demographics, time to first dose of narcotic, and pain scores were collected on patients presenting to the SCIC and ED. Maryland hospital discharge data were obtained from the Maryland Health Services Cost Review Commission. Analyses were conducted using T tests, χ(2) tests, and simple generalized estimating equation regression models accounting for the clustered nature of observations, as appropriate. There were 3,874 visits to the SCIC by 361 unique patients; 85% of those visits resulted in the patient being sent home. During the same time period, there were 3,408 visits to the ED by 558 unique patients with SCD. The overall admission rate from the ED for these patients was 35.9% but decreased significantly over the time period with a rate of 20% in December 2011. There was a significant decrease in readmissions over time for the entire Baltimore Metro area with the likelihood of readmission decreasing by 7% over time. The SCIC model provides adults with SCD access to high quality care that decreases the need for hospital admission. Further research needs to be done to evaluate the cost effectiveness of this model. © 2015 Wiley Periodicals, Inc.

    Treatment for acute lymphoblastic leukemia (ALL) in adults confers a high risk of venous thromboembolic (VTE) complications. We describe the implementation and results of prophylactic anticoagulation guidelines in adults (18-50 years) treated on a Dana-Farber Cancer Institute ALL pediatric inspired consortium protocol from 2007 to 2013. A high rate of asparaginase related toxicity events, including thrombosis, resulted in a protocol amendment adding guidelines for prophylactic anticoagulation and a modified asparaginase dose and schedule. After excluding patients with Philadelphia positive ALL, a cohort of 36 patients were treated after the protocol amendment with prophylactic anticoagulation and compared to 49 patients who received no prophylactic anticoagulation. Bleeding complications were not significantly different in those treated with prophylactic anticoagulation compared with those enrolled prior to the amendment (p = 0.26). No patients on prophylactic anticoagulation had grade ≥ 3 bleeding. Prior to the amendment, the 2 year cumulative incidence of VTE post-induction was 41% compared to 28% while on prophylactic anticoagulation (p = 0.32). The 2 year cumulative incidence pulmonary embolus pre-amendment was 16% compared with 8% post-amendment (p = 0.34). Prophylactic anticoagulation can be safely administered to adults with ALL without increasing the number or severity of bleeding events and, in addition to modifications in the asparaginase regimen, resulted in a reduction in the cumulative incidence of VTE.

    Significant advances have been made in recent years in the field of Philadelphia-negative acute lymphoblastic leukaemia (ALL). New insights into the biology and genetics of ALL as well as novel clinical observations and new drugs are changing the way we diagnose, risk-stratify and treat adult patients with ALL. New genetic subtypes and alterations refine risk stratification and uncover new actionable therapeutic targets. The incorporation of more intensive, paediatric and paediatric-inspired approaches for young adults seem to have a positive impact on survival in this population. Minimal residual disease at different time points can assist in tailoring risk-adapted interventions for patients based on individual response. Finally, novel targeted approaches with monoclonal antibodies, immunotherapies and small molecules are moving through clinical development and entering the clinic. The aim of this review is to consolidate the abundance of emerging data and to review and revisit the concepts of risk-stratification, choice of induction and post-remission strategies as well as to discuss and update the approach to specific populations with ALL, such as young adult, elderly/unfit and relapsed/refractory patients with ALL. © 2017 John Wiley & Sons Ltd.

    BACKGROUND. Airflow obstruction is common in cystic fibrosis (CF), yet the underlying pathogenesis remains incompletely understood. People with CF often exhibit airway hyperresponsiveness, CF transmembrane conductance regulator (CFTR) is present in airway smooth muscle (ASM), and ASM from newborn CF pigs has increased contractile tone, suggesting that loss of CFTR causes a primary defect in ASM function. We hypothesized that restoring CFTR activity would decrease smooth muscle tone in people with CF. METHODS. To increase or potentiate CFTR function, we administered ivacaftor to 12 adults with CF with the G551D-CFTR mutation; ivacaftor stimulates G551D-CFTR function. We studied people before and immediately after initiation of ivacaftor (48 hours) to minimize secondary consequences of CFTR restoration. We tested smooth muscle function by investigating spirometry, airway distensibility, and vascular tone. RESULTS. Ivacaftor rapidly restored CFTR function, indicated by reduced sweat chloride concentration. Airflow obstruction and air trapping also improved. Airway distensibility increased in airways less than 4.5 mm but not in larger-sized airways. To assess smooth muscle function in a tissue outside the lung, we measured vascular pulse wave velocity (PWV) and augmentation index, which both decreased following CFTR potentiation. Finally, change in distensibility of <4.5-mm airways correlated with changes in PWV. CONCLUSIONS. Acute CFTR potentiation provided a unique opportunity to investigate CFTR-dependent mechanisms of CF pathogenesis. The rapid effects of ivacaftor on airway distensibility and vascular tone suggest that CFTR dysfunction may directly cause increased smooth muscle tone in people with CF and that ivacaftor may relax smooth muscle.

    The neuro-anatomical substrates of major depressive disorder (MDD) are still not well understood, despite many neuroimaging studies over the past few decades. Here we present the largest ever worldwide study by the ENIGMA (Enhancing Neuro Imaging Genetics through Meta-Analysis) Major Depressive Disorder Working Group on cortical structural alterations in MDD. Structural T1-weighted brain magnetic resonance imaging (MRI) scans from 2148 MDD patients and 7957 healthy controls were analysed with harmonized protocols at 20 sites around the world. To detect consistent effects of MDD and its modulators on cortical thickness and surface area estimates derived from MRI, statistical effects from sites were meta-analysed separately for adults and adolescents. Adults with MDD had thinner cortical gray matter than controls in the orbitofrontal cortex (OFC), anterior and posterior cingulate, insula and temporal lobes (Cohen's d effect sizes: -0.10 to -0.14). These effects were most pronounced in first episode and adult-onset patients (>21 years). Compared to matched controls, adolescents with MDD had lower total surface area (but no differences in cortical thickness) and regional reductions in frontal regions (medial OFC and superior frontal gyrus) and primary and higher-order visual, somatosensory and motor areas (d: -0.26 to -0.57). The strongest effects were found in recurrent adolescent patients. This highly powered global effort to identify consistent brain abnormalities showed widespread cortical alterations in MDD patients as compared to controls and suggests that MDD may impact brain structure in a highly dynamic way, with different patterns of alterations at different stages of life.

Prospective observational study between 2007 and 2010 in primary care in 12 European countries. Adults presenting with acute cough (duration of ≤28 days) were included. Bordetella pertussis infection was determined by polymerase chain reaction (from nasopharyngeal flocked swabs and sputa) and by measurement of immunoglobulin G antibodies to pertussis toxin (PT) in venous blood at day 28. An antibody titre to PT of ≥125 IU/ml or PCR positive result in a respiratory sample defined recent infection. Patients completed a symptom diary for 28 days. Serum and/or respiratory samples were obtained in 3074 patients. Three per cent (93/3074) had recent B. pertussis infection. Prior cough duration >2 weeks discriminated to some extent between those with and without pertussis (adjusted odds ratio 1.89, 95% confidence interval = 1.17 to 3.07; P = 0.010). Median cough duration after presentation was 17 and 12 days in patients with and without pertussis, respectively (P = 0.008). Patients with pertussis had longer duration of phlegm production (P = 0.010), shortness of breath (P = 0.037), disturbed sleep (P = 0.013) and interference with normal activities or work (P = 0.033) after presentation. Pertussis infection plays a limited role among adults presenting with acute cough in primary care, but GPs should acknowledge the possibility of pertussis in uncomplicated lower respiratory tract infection. As in children, pertussis also causes prolonged symptoms in adults. However, pertussis is difficult to discern from other acute cough syndromes in adults at first presentation. © British Journal of General Practice 2015.

    Febrile adults are usually not tested for acute HIV-1 infection (AHI) in Africa. We assessed a strategy to diagnose AHI among young adult patients seeking care. Young adults (defined as a positive p24 antigen test, and subsequent seroconversion or RNA detection. Febrile patients evaluated for AHI were also screened for malaria using a rapid test, with PCR confirmation of positives. In 3602 adults seeking care, overall HIV-1 prevalence was 3.9%: 7.6% (68/897) among patients meeting AHI criteria vs. 2.6% (71/2705) among those who did not (P young febrile adults seeking care. An AHI detection strategy targeting young febrile adults seeking care at pharmacies and health facilities is feasible and should be considered as an HIV-prevention strategy in high-transmission settings.

    To assist the clinician in making decisions about the types of care available for adults with schizophrenia. To determine which are the modalities of treatment associated with better outcomes in adults with schizophrenia. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. The evidence of NICE guide 82 was adopted and updated. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. Patients who were in Assertive community treatment had a lower risk of new hospitalizations. For the intensive case management, the results favored this intervention in the outcomes: medium term readmissions, social functioning and satisfaction with services. The crisis resolution teams was associated with better outcomes on outcomes of readmissions, social functioning and service satisfaction in comparison with standard care. The use of different modalities of care leads to the need of a comprehensive approach to patients to reduce the overall disability associated with the disease. Evidence shows overall benefit for most outcomes studied without encountering hazards for health of patients. This evaluation is recommended to use the professional ways of providing health services that are community-based and have a multidisciplinary group. It is not recommended the modality "day hospital" during the acute phase of schizophrenia in adults. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    The complex interplay between hypernatremic osmotic disturbances and cerebral lesions is yet to be clarified. In this review, we discuss, on the basis of the reported data of hypernatremic CNS challenge in the adult population, the clinical and radiologic features of the condition. Our search captured 20 case studies and 1 case series with 30 patients in total who acquired acute hypernatremia due to different etiologies and developed CNS lesions. We explored the associations between premorbid conditions, clinical presentation, hypernatremic state, correction rate, and radiologic appearance, including the localization of brain lesions and the outcomes. The results revealed that altered mental status was the most commonly reported symptom and osmotic demyelination syndrome in the form of extrapontine myelinolysis was the prevailing radiologic pattern. Finally, we contrasted, when appropriate, clinical and experimental data related to hypernatremic and hyponatremic osmotic insults to aid the understanding of the pathophysiology of CNS osmotic brain injury.

    With the goal of providing guidance on the provision of optimal intensive care to adult patients with acute liver failure (ALF), this paper defines ALF and describes a protocol for appropriately diagnosing this relatively rare clinical entity and ascertaining its etiology, where possible. This paper also identifies the few known therapies that may be effective for specific causes of ALF and provides a comprehensive approach for anticipating, identifying, and managing complications. Finally, one of the more important aspects of care for patients with ALF is the determination of prognosis and, specifically, the need for liver transplantation. Prognostic tools are provided to help guide the clinician in this critical decision process. Management of patients with ALF is complex and challenging, even in centers where staff members have high levels of expertise and substantial experience. This evidence-based protocol may, therefore, assist in the delivery of optimal care to this critically ill patient population and may substantially increase the likelihood of positive outcomes.

    Full Text Available Some epidemiological evidence shows a link between abnormality of lipid profiles and variations in serum calcium. However, it is unknown whether this association resulted from confounding factors. The present study was designed to investigate the relationship between serum lipids and calcium. Serum calcium was corrected for albumin. Major confounding factors including age, gender, medications, menopause, parathyroid hormone (PTH and 25-OH-vitamin D status were controlled in analyses. A total of 1907 adult subjects from the province of Newfoundland and Labrador (NL, Canada participated in the study. Significant positive correlations were detected between serum total cholesterol and high density lipoprotein-cholesterol (HDL-c with variations of serum Ca ++ in both genders (p < 0.05–0.0001. Significant positive correlations were additionally detected between triglycerides (TG and low density lipoprotein-cholesterol (LDL-c with Ca ++ in women only (p < 0.0001 in partial correlation analyses. Similar significant results were detected in both females and males not taking any medication. Analyses were performed based on menopausal status as well. Significant correlations were seen in both pre- and post-menopausal women but higher correlation coefficients were observed in pre-menopausal women as compared to post-menopausal women. Subjects with low calcium levels had the lowest concentration of total cholesterol, TG, HDL-c and LDL-c, while subjects with high calcium levels had the highest concentration of all four markers in women. The significant associations between cholesterol, TG and LDL-c and serum Ca ++ remained after calcium was adjusted for 25-OH-vitamin D and PTH. Our results indicate that the abnormality of serum lipid profiles are significantly correlated with altered serum Ca ++ levels independent of age, obesity status, medication, phosphorus, magnesium, 25-OH-vitamin D and PTH.

    Full Text Available Urinary tract infections (UTI cause a great number of morbidity and mortality. These infections are serious complications in pregnancy, patients with diabetes, polycystic kidneys disease, sickle cell anaemia, kidney transplant and in patients with functional or structural anomalies of the urinary tract. The aim of this investigation was to determine a dominant causative agents of UTI and some of the clinical and laboratory characteristics of acute community-acquired UTI in adult hospitalised patients. We studied 200 adult patients with acute community-acquired UTI hospitalised in the Clinic for Infectious Diseases Tuzla from January 2006 to December 2007. The patients were divided into two groups: a group of patients with E. coli UTI (147 and a group of patients with non-E. coli UTI (53. In these two groups, the symptoms and signs of illness, blood test and urine analysis results were analysed. Our results have shown that the patients with E. coli UTI frequently had fever higher than 38,5 degrees C (p<0,0001, chills (p=0,0349, headache (p=0,0499, cloudy urine (p<0,0001, proteinuria (p=0,0011 and positive nitrite-test (p=0,0002. The patients with non-E. coli UTI frequently had fever lower than 38,5 degrees C (p<0,0001 and urine specific gravity <1015 (p=0,0012. There was no significant difference in blood test results between patients with E. coli and non-E. coli UTI. These clinical and laboratory findings can lead us to early etiological diagnosis of these UTI before urine culture detection of causative agents, which takes several days. Early etiological diagnosis of the E. coli and non-E. coli UTI is necessary for an urgent administration of appropriate empirical antibiotic treatment. This is very important in prevention of irreversible kidney damage, prolonged treatment, complications, as well as recidives and chronicity of the illness.

    Despite the significant morbidity associated with renal failure after lung transplantation (LTx), no predictive models currently exist. Accordingly, the purpose of this study was to develop a preoperative risk score based on recipient-, donor-, and transplant-specific characteristics to predict postoperative acute renal failure in candidates for transplantation. The United Network of Organ Sharing (UNOS) database was queried for adult patients (≥ 18 years of age) undergoing LTx between 2005 and 2012. The population was randomly divided into derivation (80%) and validation (20%) cohorts. The primary outcome of interest was new-onset renal failure. Variables predictive of acute renal failure (exploratory p value renal failure to construct the risk stratification score (RSS). During the study period, 10,963 patients underwent lung transplantation, and the incidence of renal failure was 5.5% (598 patients). Baseline recipient-, donor-, and transplant-related factors were similar between the cohorts. Eighteen covariates were included in the multivariable model, and 10 were assigned values based on their relative odds ratios (ORs). Scores were stratified into 3 groups, with an observed rate of acute renal failure of 3.1%, 5.3%, and 15.6% in the low-, moderate-, and high-risk groups, respectively. The incidence of renal failure was found to be significantly increased in the highest risk group (p renal failure highly correlated with actual rates observed in the population (r = 0.86). We introduce a novel and simple RSS that is highly predictive of renal failure after LTx. Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

    AIM: To determine the impact of computed tomography (CT) on the diagnosis and treatment plan in patients with acute abdominal pain. MATERIALS AND METHODS: A prospective study was undertaken in 125 adult patients presenting with acute abdominal pain (74 men and 51 women; 40.2 ± 19.3 years; range, 18-92). Changes in diagnosis, gain in percentage diagnostic certainty and changes of treatment plan of the surgeons in the emergency department before and after CT were evaluated. Pre- and post-CT diagnoses were compared with the final diagnoses. RESULTS: CT findings changed the initial diagnosis in 40 (32.0%) patients. The diagnostic certainty was 58.3 ± 22.9% before CT, and its gain after CT was 21.9 ± 18.5 points (P < 0.0001). Post-CT diagnoses were consistent with the final diagnosis in 116 patients (92.8%), while pre-CT diagnoses were correct in 89 patients (71.2%; P < 0.0001). Initial treatment plans were changed in 31 (24.8%) patients after CT. In 57 (45.6%) patients, CT information changed diagnoses and/or treatment plans. No significant differences were observed in the diagnosis, diagnostic certainty and treatment plan among four surgeons. CONCLUSION: Contrast-enhanced CT frequently changed the clinical diagnoses with increased diagnostic certainty and the initial treatment plans. Tsushima, Y. et al. (2002)

    Full Text Available Human T-cell leukemia virus type-1 (HTLV-1 is the causative agent of adult T-cell leukemia (ATL. Hypercalcemia is common in patients with ATL. These patients rarely develop metastatic calcification and acute pancreatitis. The underlying pathogenesis of this condition is osteoclast hyperactivity with associated overproduction of parathyroid hormone-related protein, which results in hypercalcemia in association with bone demineralization. The discovery of the osteoclast differentiation factor receptor activator of nuclear factor-κB ligand (RANKL, its receptor RANK, and its decoy receptor osteoprotegerin (OPG, enhanced our understanding of the mechanisms of ATL-associated hypercalcemia. Macrophage inflammatory protein-1-α, tumor necrosis factor-α, interleukin-1, and interleukin-6 are important molecules that enhance the migration and differentiation of osteoclasts and the associated enhanced production of RANKL for osteoblast formation. In this paper, we focus on metastatic calcification and acute pancreatitis in ATL, highlighting recent advances in the understanding of the molecular role of the RANKL/RANK/OPG system including its interaction with various cytokines and calciotropic hormones in the regulation of osteoclastogenesis for bone resorption in hypercalcemic ATL patients.

    Accidental radiation exposure and the threat of deliberate radiation exposure have been in the news and are a public health concern. Experience with acute radiation sickness has been gathered from atomic blast survivors of Hiroshima and Nagasaki and from civilian nuclear accidents as well as experience gained during the development of radiation therapy for cancer. This paper reviews the medical treatment reports relevant to acute radiation sickness among the survivors of atomic weapons at Hiroshima and Nagasaki, among the victims of Chernobyl, and the two cases described so far from the Fukushima Dai-Ichi disaster. The data supporting the use of hematopoietic stem cell transplantation and the new efforts to expand stem cell populations ex vivo for infusion to treat bone marrow failure are reviewed. Hematopoietic stem cells derived from bone marrow or blood have a broad ability to repair and replace radiation induced damaged blood and immune cell production and may promote blood vessel formation and tissue repair. Additionally, a constituent of bone marrow-derived, adult pluripotent stem cells, very small embryonic like stem cells, are highly resistant to ionizing radiation and appear capable of regenerating radiation damaged tissue including skin, gut and lung.

    Full Text Available BACKGROUND: Thrombotic microangiopathies (TMA in adults such as thrombotic thrombocytopenic purpura (TTP and hemolytic uremic syndrome (HUS are life-threatening disorders if untreated. Clinical presentation is highly variable and prognostic factors for clinical course and outcome are not well established. METHODS: We performed a retrospective observational study of 62 patients with TMA, 22 males and 40 females aged 16 to 76 years, treated with plasma exchange at one center to identify clinical risk factors for the development of renal insufficiency. RESULTS: On admission, 39 of 62 patients (63% had acute renal failure (ARF with 32 patients (52% requiring dialysis treatment. High systolic arterial pressure (SAP, p = 0.009 or mean arterial pressure (MAP, p = 0.027 on admission was associated with acute renal failure. Patients with SAP>140 mmHg on admission had a sevenfold increased risk of severe kidney disease (OR 7.464, CI 2.097-26.565. MAP>100 mmHg indicated a fourfold increased risk for acute renal failure (OR 4.261, CI 1.400-12.972. High SAP, diastolic arterial pressure (DAP, and MAP on admission were also independent risk factors for persistent renal insufficiency with the strongest correlation for high MAP. Moreover, a high C-reactive protein (CRP level on admission correlated with renal failure in the course of the disease (p = 0.003. At discharge, renal function in 11 of 39 patients (28% had fully recovered, 14 patients (23% remained on dialysis, and 14 patients (23% had non-dialysis-dependent chronic kidney disease. Seven patients (11% died. We identified an older age as risk factor for death. CONCLUSIONS: High blood pressure as well as high CRP serum levels on admission are associated with renal insufficiency in TMA. High blood pressure on admission is also a strong predictor of sustained renal insufficiency. Thus, adult TMA patients with high blood pressure may require special attention to prevent persistent renal failure.

This evidence is used to propose recommendation in the guidelines of integral attention for the diagnosis, treatment and psychosocial rehabilitation of adults with schizophrenia. A guideline for clinical practice was developed using the methodological framework of the Ministerio de la Protección Social to collect evidence and grading recommendations. A search, evaluation and synthesis of evidence were carried out. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. The cognitive behavioral therapy showed higher efficacy, compared with the usual treatment, to reduce positive symptoms, prevent relapses and hospital readmissions and to improve the occupational stats. However, the quality of evidence was low. There was not enough evidence about the efficacy of adherence, psychodynamic and support therapy. Psychotherapeutic management must be offered to the patients with schizophrenia according to their needs and clinical characteristics. Among the different psychotherapeutic modalities, cognitive behavioral therapy is recommended. Copyright © 2014 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

    To determine the influence of tobacco exposure in the development of metabolic syndrome (MS) in the adult Saudi population. Six hundred and sixty-four adults (305 males and 359 females) aged 25-70 years were included in this cross-sectional study conducted at the King Abdul Aziz University Hospital, between June 2006 and May 2007. We classified the participants into non-smokers, smokers, and ex-smokers (defined as complete cessation for 1-2 years). All subjects were screened for the presence of MS using the modified American Heart Association/National Heart, Lung and Blood Institute (AHA/NHLBI), International Diabetes Federation (IDF) and World Health Organization (WHO) definitions. Metabolic syndrome was highest among ex-smokers regardless of definition used. Relative risk for ex-smokers (95% CI: 2.23, 1.06-4.73) was more than twice in harboring MS as compared to non-smokers (95% CI: 2.78, 1.57-4.92) (p=0.009). Acute post-cessation smoking is a strong predictor for MS among male and female Arabs. Smoking cessation programs should include a disciplined lifestyle and dietary intervention to counteract the MS-augmenting side-effect of smoking cessation. (author)

    2014-11-01

    Full Text Available In adult patients with acute lymphoblastic leukemia (ALL, Central Nervous System (CNS involvement is associated with a very poor prognosis. The diagnostic assessment of this condition relies on the use of neuroradiology, conventional cytology (CC and flow cytometry (FCM. Among these approaches, which is the gold standard it is still a matter of debate. Neuroradiology and CC have a limited sensitivity with a higher rate of false negative results. FCM demonstrated a superior sensitivity over CC, particularly when low levels of CNS infiltrating cells are present. Although prospective studies of large series of patients are still awaited, a positive finding by FCM appears to anticipate an adverse outcome even if CC shows no infiltration. Current strategies for adult ALL CNS-directed prophylaxis or therapy involve systemic and intrathecal chemotherapy and radiation therapy. Actually, early and frequent intrathecal injection of cytostatic combined with systemic chemotherapy is the most effective strategy to reduce the frequency of CNS involvement. In patients with CNS overt ALL, at diagnosis or upon relapse, allogenic hematopoietic stem cell transplantation might be considered. This review will discuss risk factors, diagnostic techniques for identification of CNS infiltration and modalities of prophylaxis and therapy to manage it.

    Full Text Available Introduction. Occurrence of acute myocardial infarction in young adults is a relatively rare. In majority of the studies, age of 45 years is used as cut-off line in definition of the young patients with coronary artery disease or myocardial infarction. Studies have shown that younger population aged less than 40 years represents only 2-8% of all patients with myocardial infarction. Objective. The aim of this study was to examine the specificities of clinical and angiographic characteristics of the patients recovered from acute myocardial infarction, younger than 45 years at the moment of attack, by comparing their clinical and angiographic characteristics with those of patients older than 65 years, who recovered from acute myocardial infarction. Method. The study included 78 patients recovered from acute myocardial infarction, 33 patients were younger than 45 years (40.7 ± 3.9 years, 25 (75.7% men and eight (24.2% female, and 45 patients were older than 65 years (68.2 ± 4.2 years, 32 (71.3% men and 13 women. Detailed history taking, physical examination, permanent ECG monitoring, laboratory analyses, X-ray examination, echocardiography and selective coronarography of all patients were performed. Results. Patients younger than 45 years had a significantly higher incidence of STEMI (p 0.05 Multivessel disease existed at 54.5% under the age of 45 and 77.8% older than 65 years (p0.05. The disease of left main coronary artery had 6.1% of patients younger than 45 and 22.2% of patients older than 65 years (p0.05 Were without significant coronary artery stenosis Comparing risk factors for coronary artery disease in patients younger than 45 years and older than 65 years, we find: hypertension in 48.5% vs. 88.9% (p0.05, diabetes mellitus in 21.2% vs. 55.5% (p 0.05, and stress in 18.2% vs. 2.2% (p <0.01.

    Although exercise has multiple health benefits, relatively little attention has been paid to its potential therapeutic effects in those with asthma. To examine the effects of acute exercise on inflammation in physically inactive and active adults with asthma. Fourteen adults with asthma (n = 6 physically inactive, n = 8 physically active) completed (1) 30 minutes of moderate-intensity exercise on a treadmill and (2) 30 minutes of rest in random order, with 4 weeks between sessions. Exhaled nitric oxide (eNO) was measured before and after the intervention (0, 0.5, 1, 2, 4, and 24 hours). Blood inflammatory mediators were measured before and after the intervention (0, 2, and 24 hours). Physically inactive participants had a significant decrease in eNO 4 hours after exercise (-4.8 ppb, -6.4 to -0.5 ppb, P = .028), which was not observed in physically active participants (P = .362). Interluekin-1 receptor antagonist increased in the physically inactive group 2 hours after exercise, with this increase strongly correlated with the decrease in eNO at 4 hours (R = -0.685, P = .007) and 24 hours (R = -0.659, P = .014) after exercise. Interleukin-6 was increased significantly 2 hours after exercise in physically inactive participants. Blood neutrophils and nuclear factor erythroid 2-like 2 gene expression were increased 2 hours after exercise in the overall cohort. This study demonstrates that acute moderate-intensity exercise is associated with decreased eNO in physically inactive adults with asthma and suggests that interluekin-1 receptor antagonist could have a role in mediating this effect. The attenuated response in physically active participants might be due to the sustained anti-inflammatory effects of exercise training. Future studies should investigate the impact of exercise intensity and exercise training on airway inflammation in those with asthma.

    The CT pattern of bilateral and symmetrical round low density areas in the globi pallidi has been observed in a young man who attempted suicide by hanging. These CT abnormalities are similar to those described in other conditions such as carbon monoxide, hydrogen sulfide, cyanide and methanol poisoning, hypoglycaemia, drowning and acute global central nervous system hypoperfusion.The findings appear to be correlated with acute cerebral hypoxia.

    Minimal residual disease (MRD) studies in adult acute lymphoblastic leukemia (ALL) give highly significant prognostic information superior to other standard criteria as age, gender and total leucocytic count (TLC) in distinguishing patients at high and low risk of relapse. We aimed to determine the value of MRD monitoring by flowcytometry (FCM) in predicting outcome in adult Precursor ALL patients. Bone marrow (BM) samples were analyzed by 4-color FCM collected at diagnosis and after induction therapy (MRD1) to correlate MRD positivity with disease free survival (DFS) and overall survival (OS). Study included 57 adult ALL patients (44 males and 13 females) with a median age of 22 years (18-49). DFS showed no significant difference with age, gender and initial TLC (p=0.838, 0.888 and 0.743, respectively). Cumulative DFS at 2 years was 34% for B-lineage ALL (n: 35) and 57% for T-lineage ALL (n: 18) (p = 0.057). Cumulative DFS at 2 years was 7% for MRD1 positive (high risk, HR) versus 57% for MRD1 negative patients (Low risk, LR) (p MRD1, OS at 2 years was 18% for MRD1 HR (n: 17) versus 65% for MRD1 LR (n: 38) (p < 0.001). OS was 35% for high-risk patients (n: 30) and 62% for low-risk patients (n: 27) classified according to GMALL risk stratification (p = 0.017). MRD by FCM is a strong independent predictor of outcome in terms of DFS and OS and is a powerful informative parameter in guiding individual treatment in ALL patients. Copyright © 2013.

    Obesity is a chronic and multifactorial disease, whose prevalence is increasing in many countries. Pharmaceutical strategies for the treatment of obesity include drugs that regulate food intake, thermogenesis, fat absorption, and fat metabolism. Fenproporex is the second most commonly consumed amphetamine-based anorectic worldwide; this drug is rapidly converted in vivo into amphetamine, which is associated with neurotoxicity. In this context, the present study evaluated DNA damage parameters in the peripheral blood of young and adult rats submitted to an acute administration and chronic administration of fenproporex. In the acute administration, both young and adult rats received a single injection of fenproporex (6.25, 12.5 or 25 mg/kg i.p.) or vehicle. In the chronic administration, both young and adult rats received one daily injection of fenproporex (6.25, 12.5, or 25 mg/kg i.p.) or Tween for 14 days. 2 h after the last injection, the rats were killed by decapitation and their peripheral blood removed for evaluation of DNA damage parameters by alkaline comet assay. Our study showed that acute administration of fenproporex in young and adult rats presented higher levels of damage index and frequency in the DNA. However, chronic administration of fenproporex in young and adult rats did not alter the levels of DNA damage in both parameters of comet assay. The present findings showed that acute administration of fenproporex promoted damage in DNA, in both young and adult rats. Our results are consistent with other reports which showed that other amphetamine-derived drugs also caused DNA damage. We suggest that the activation of an efficient DNA repair mechanism may occur after chronic exposition to fenproporex. Our results are consistent with other reports that showed some amphetamine-derived drugs also caused DNA damage.

    We performed a retrospective study comparing computed tomography (CT) and DMSA- 99m Tc scintigraphy (DMSA) in the evaluation of renal disease in acute pyelonephritis. Thirty-four 39± 20 year old female patients were studied. DMSA scintigraphy was performed 11.4±5.8 days after infection onset. Planar posterior views were obtained 4 to 6 hours after injection of 80 MBq of 99m Tc-DMSA. Renal uptake was also quantified after kidney depth had been measured by ultrasonography. CT was performed with and without bolus injection of contrast medium 15.5± 10.6 days after infection onset. DMSA images were read independently by three blind NM doctors, using three posterior views. Cortical renal defects were evaluated on three different renal segments on the top, middle and bottom. CT films were also read by three expert physicians. Thirty-two out of 34 patients had renal cortical defects on DMSA and 17 had only CT consistent with pyelonephritis. Cortical defects were bilateral in 22 out of 32 patients and in three out of 17 CT studies. Bilateral and left kidney lesions on CT (five cases) were also present on DMSA. Four out of 12 patients with isolated right kidney abnormalities at CT scan showed defects limited to the right kidney on DMSA, but eight had bilateral defects. After exclusion of two patients with renal failure, ten normal kidneys had a 22.9±5.4 % uptake that was significantly different from that of damaged kidneys (18.8±7.4 %), p<0.05. In 204 renal segments, 29 showed a concordant defect on CT and DMSA, and 127 were normal on both scans. Eighteen showed defects on CT but did not on DMSA, 27 were CT negative but DMSA positive, with three DMSA false positives due to renal cysts. We concluded that DMSA cortical renal scan appears to be more sensitive than CT to evaluate renal damage in patients with acute pyelonephritis. (authors)

    Full Text Available Abstract Background Allogenic hematopoietic stem cell transplantation (allo-SCT is the most effective post-remission treatment for adults with high-risk acute lymphoblastic leukemia (ALL. The aim of the study was to analyze results of unmanipulated haploidentical allo-SCT (haplo-SCT for adults with ALL and to identify prognostic factors. Methods We performed a retrospective analysis on 208 adults transplanted in EBMT centers from 2007 to 2014. Results Median age at haplo-SCT was 32 years and median follow-up, 31 months. Forty-four percent of the patients were in first complete remission (CR1. Stem cell source was the bone marrow (BM for 43% and peripheral blood (PB for 57% of patients. Myeloablative conditioning (MAC was used for 66% and reduced intensity regimen (RIC for 34% of patients. GVHD prophylaxis was based on post-transplant cyclophosphamide (PT-Cy for 118 (57% or on anti-thymocyte-globulin (ATG for 90 (43% plus standard prophylaxis. One hundred eighty-four (92% patients achieved engraftment. Cumulative incidence (CI of grade II–IV acute-graft-versus-host-disease (GVHD was 31%, grade III–IV 11%, and chronic GVHD 29%. Non-relapse mortality (NRM and relapse-incidence (RI were 32 and 37%, respectively. Overall survival (OS, leukemia-free survival (LFS, and GVHD-free, relapse-free-survival (GRFS at 3 years were 33, 31, and 26%. For patients in CR1, OS, LFS, and GRFS were 52, 47, and 40%, respectively. Disease status was the main factor associated with transplant outcomes. Use of BM was independently associated with improvement in NRM, acute GVHD, GRFS, LFS, and OS. Conclusions Unmanipulated haplo-SCT may be considered a valid option for adult patients with high-risk ALL lacking HLA identical donor preferably in early disease status.

    Ketoprofen is a non-selective non-steroidal anti-inflammatory drug (NSAID) used to treat acute and chronic painful conditions. Dexketoprofen is the (S)-enantiomer, which is believed to confer analgesia. Theoretically dexketoprofen is expected to provide equivalent analgesia to ketoprofen at half the dose, with a consequent reduction in gastrointestinal adverse events. To assess efficacy, duration of action, and associated adverse events of single dose oral ketoprofen and dexketoprofen in acute postoperative pain in adults. We searched Cochrane CENTRAL, MEDLINE, EMBASE and the Oxford Pain Relief Database for studies to August 2009. Randomised, double blind, placebo-controlled trials of single dose orally administered ketoprofen and dexketoprofen in adults with moderate to severe acute postoperative pain. Two review authors independently assessed trial quality and extracted data. Pain relief or pain intensity data were extracted and converted into the dichotomous outcome of number of participants with at least 50% pain relief over 4 to 6 hours, from which relative risk and number-needed-to-treat-to-benefit (NNT) were calculated. Numbers of participants using rescue medication over specified time periods, and time to use of rescue medication, were sought as additional measures of efficacy. Information on adverse events and withdrawals was collected. Fourteen studies compared ketoprofen (968 participants) at mainly 25 mg and 50 mg with placebo (520 participants). Seven studies compared dexketoprofen (681 participants) at mainly 10 mg to 25 mg with placebo (289 participants). Studies were of adequate reporting quality, and participants had pain following dental, orthopaedic, obstetric, gynaecological and general surgery. There was considerable clinical heterogeneity between studies in dental and other types of surgery, particularly bunionectomy, which limited analysis.Ketoprofen at doses between 12.5 mg and 100 mg produced NNTs for at least 50% pain relief over 4 to 6

    Full Text Available Neonatal rats have a high intestinal lactase activity, which declines around weaning. Yet, the effects of lactose-containing products are often studied in adult animals. This report is on the residual, post-weaning lactase activity and on the short- and long-term effects of lactose exposure in adult rats. Acutely, the postprandial plasma response to increasing doses of lactose was studied, and chronically, the effects of a 30% lactose diet fed from postnatal (PN Day 15 onwards were evaluated. Intestinal lactase activity, as assessed both in vivo and in vitro, was compared between both test methods and diet groups (lactose vs. control. A 50%–75% decreased digestive capability towards lactose was observed from weaning into adulthood. Instillation of lactose in adult rats showed disproportionally low increases in plasma glucose levels and did not elicit an insulin response. However, gavages comprising maltodextrin gave rise to significant plasma glucose and insulin responses, indicative of a bias of the adult GI tract to digest glucose polymers. Despite the residual intestinal lactase activity shown, a 30% lactose diet was poorly digested by adult rats: the lactose diet rendered the animals less heavy and virtually devoid of body fat, whereas their cecum tripled in size, suggesting an increased bacterial fermentation. The observed acute and chronic effects of lactose exposure in adult rats cannot be explained by the residual intestinal lactase activity assessed.

    Adolescence is a phase of development during which many physiological and behavioral changes occur, including increased novelty seeking and risk taking. In humans, this is reflected in experimentation with drugs. Research demonstrates that drug use that begins during adolescence is more likely to lead to addiction than drug use that begins later in life. Despite this, relatively little is known of the effects of drugs in adolescence, and differences in response between adolescents and adults. PCP and ketamine are popular club drugs, both possessing rewarding properties that could lead to escalating use. Drug sensitization (or reverse tolerance), which refers to an increase in an effect of a drug following repeated use, has been linked with the development of drug cravings that is a hallmark of addiction. The current work investigated the acute response and the development of sensitization to PCP and ketamine in adolescent and adult rats. Periadolescent Sprague-Dawley rats (30days or 38days of age), and young adults (60days of age) received PCP (6mg/kg IP) or ketamine (20mg/kg IP) once every three days, for a total of five drug injections. Adolescents and adults showed a stimulant response to the first injection of either drug, however the response was considerably greater in the youngest adolescents and lowest in the adults. With repeated administration, adults showed a robust escalation in activity that was indicative of the development of sensitization. Adolescents showed a flatter trajectory, with similar high levels of activity following an acute treatment and after five drug treatments. The results demonstrate important distinctions between adolescents and adults in the acute and repeated effects of PCP and ketamine. Copyright © 2017 Elsevier Inc. All rights reserved.

    To determine the most adequate strategies for the prevention and treatment of the acute adverse effects of the use of antipsychotics. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. A systematic literature search was carried out. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. The non-pharmacological interventions such as nutritional counseling by a nutritionist, exercise and psychotherapy are effective in preventing weight gain with the use of antipsychotics. (Kg Weight reduction in DM of -3.05 (-4.16, -1.94)). The antipsychotic change from olanzapine to aripiprazole showed weight loss and decreased BMI (decreased weight in KG DM -3.21 (-9.03, -2.61). The use of beta blockers was ineffective in reducing akathisia induced by antipsychotic; using as outcome the 50% reduction of symptoms of akathisia comparing beta-blockers with placebo RR was 1.4 (0.59, 1.83). It is recommended to make psychotherapeutic accompaniment and nutrition management of overweight for patients with weight gain. If these alternatives are ineffective is suggested to change the antipsychotic or consider starting metformin. For the management of drug-induced akathisia it is recommended to decrease the dose of the drug and the addition of lorazepam. It is recommended using 5mg biperiden IM or trihexyphenidyl 5mg orally in case of secondary acute dystonia and for the treatment of antipsychotic-induced parkinsonism to decrease the dose of antipsychotic or consider using 2 - 4mg/day of biperiden or diphenhydramine 50mg once daily.

    OBJECTIVES: to describe hospital pharmacy involvement in medication management in Ireland, both generally and at points of transfer of care, and to gain a broad perspective of the hospital pharmacy workforce. METHODS: a survey of all adult, acute, public hospitals with an accident and emergency (A&E) department (n = 36), using a semi-structured telephone interview. KEY FINDINGS: there was a 97% (n = 35) response rate. The majority (n = 25, 71.4%) of hospitals reported delivery of a clinical pharmacy service. On admission, pharmacists were involved in taking or verifying medication histories in a minority (n = 15, 42.9%) of hospitals, while few (n = 6,17.1%) deployed staff to the A&E\\/acute medical admissions unit. On discharge, the majority (n = 30,85.7%) did not supply any take-out medication, a minority (n =5,14.3%) checked the discharge prescription, 51.4% (n = 18) counselled patients, 42.9% (n = 15) provided medication compliance charts and one hospital (2.9%) communicated with the patient\\'s community pharmacy. The number of staff employed in the pharmacy department in each hospital was not proportionate to the number of inpatient beds, nor the volume of admissions from A&E. There were differences identified in service delivery between hospitals of different type: urban hospitals with a high volume of admissions from A&E were more likely to deliver clinical pharmacy. CONCLUSIONS: the frequency and consistency of delivering pharmacy services to facilitate medication reconciliation at admission and discharge could be improved. Workforce constraints may inhibit service expansion. Development of national standards of practice may help to eliminate variation between hospitals and support service development.

    Ureterocele is a cystic dilation of the distal ureteral segment. The incidence in women ranges from 1/5,000 to 1/12,000. In adults, they are poorly diagnosed and are asymptomatic. Prolapse through the urethra is uncommon, and involves acute urine retention and a reducible vulvar tumour. Woman of 24 years old, two previous caesarean and two abortions. She had incomplete bladder emptying, intermittent voiding, bladder straining and tenesmus, three months before admission. After the voiding effort she presented with acute urine retention with sudden onset of tumour in the vulva. The tumour was manually reduced under regional anaesthesia. A cystoscopy was performed, finding an ischaemic de-roofing of the anterior wall of the ureterocele, causing vesicoureteral reflux grade IV. Surgical correction was performed with Cohen re-implantation and insertion of a double-J catheter. The catheter was removed 30 days later, with a successful post-operative course. Its aetiology is unclear, and most are diagnosed by ultrasound in the prenatal period. The clinical presentation is variable, from urinary tract infection to prolapse. Despite its size, it may cause complications such as ischaemic de-roofing, which if diagnosed soon may be resolved successfully, as with this patient. The results and treatment may be favourable when no renal impact or concomitant anatomical changes are present, as is the case of this patient. Copyright © 2015 Academia Mexicana de Cirugía A.C.

    2002-06-01

    Full Text Available Abstract Background Rofecoxib is a cyclo-oxygenase 2 selective inhibitor. This systematic review of rofecoxib in acute pain examined studies in adults of analgesic efficacy over six hours, the amount and quality of the evidence on extended duration of analgesia, and the quality and quantity of evidence on adverse events. Methods Cochrane Library (issue 4, 2001, Biological Abstracts (March 2002, MEDLINE (March 2002 and PubMed (March 2002 were searched using rofecoxib as a free text term. The area under the pain relief versus time curve was dichotomized using validated equations to derive the proportion of patients on rofecoxib 50 mg or placebo with at least 50% pain relief over six hours. This was used to calculate the number needed to treat for at least 50% pain relief over six hours for rofecoxib compared with placebo. Information on duration of analgesia and adverse events was also collected. Results Five included trials investigated 1,118 patients, of whom 211 received placebo and 464 received rofecoxib 50 mg. The NNT for rofecoxib 50 mg was 2.3 (95% confidence interval 2.0 to 2.6. The weighted mean remedication time was 1.9 hours for placebo (126 patients, 7.4 hours for ibuprofen 400 mg (97 patients and 13.6 hours for rofecoxib 50 mg (322 patients. Conclusion Rofecoxib at 2–4 times the standard daily dose for chronic pain is an effective single dose oral analgesic in acute pain. Limitations in trial reporting constrain conclusions about longer duration of analgesia and adverse event profile.

    Genetic lesions such as BCR-ABL1, E2A-PBX1, and MLL rearrangements (MLLr) are associated with unfavorable outcomes in adult B-cell precursor acute lymphoblastic leukemia (B-ALL). Leukemia oncoproteins may directly or indirectly disrupt cytosine methylation patterning to mediate the malignant phenotype. We postulated that DNA methylation signatures in these aggressive B-ALLs would point toward disease mechanisms and useful biomarkers and therapeutic targets. We therefore conducted DNA methylation and gene expression profiling on a cohort of 215 adult patients with B-ALL enrolled in a single phase III clinical trial (ECOG E2993) and normal control B cells. In BCR-ABL1-positive B-ALLs, aberrant cytosine methylation patterning centered around a cytokine network defined by hypomethylation and overexpression of IL2RA(CD25). The E2993 trial clinical data showed that CD25 expression was strongly associated with a poor outcome in patients with ALL regardless of BCR-ABL1 status, suggesting CD25 as a novel prognostic biomarker for risk stratification in B-ALLs. In E2A-PBX1-positive B-ALLs, aberrant DNA methylation patterning was strongly associated with direct fusion protein binding as shown by the E2A-PBX1 chromatin immunoprecipitation (ChIP) sequencing (ChIP-seq), suggesting that E2A-PBX1 fusion protein directly remodels the epigenome to impose an aggressive B-ALL phenotype. MLLr B-ALL featured prominent cytosine hypomethylation, which was linked with MLL fusion protein binding, H3K79 dimethylation, and transcriptional upregulation, affecting a set of known and newly identified MLL fusion direct targets with oncogenic activity such as FLT3 and BCL6. Notably, BCL6 blockade or loss of function suppressed proliferation and survival of MLLr leukemia cells, suggesting BCL6-targeted therapy as a new therapeutic strategy for MLLr B-ALLs. We conducted the first integrative epigenomic study in adult B-ALLs, as a correlative study to the ECOG E2993 phase III clinical trial. This

    Interrogate the impact of IKZF1 deletion on therapy-outcomes of adults with common B-cell acute lymphoblastic leukemia. One hundred sixty-five consecutive adults with common B-cell ALL were tested for IKZF1 deletion and for BCR/ABL. Deletions in IKZF1 were detected using multiplex RQ-PCR, multiplex fluorescent PCR, sequence analysis and multiplex ligation-dependent probe amplification (MLPA). BCR/ABL was detected using RQ-PCR. All subjects received chemotherapy and some also received an allotransplant and tyrosine kinase-inhibitors. Multivariate analyses were done to identify associations between IKZF1 deletion and other variables on non-relapse mortality (NRM), cumulative incidence of relapse (CIR), leukemia-free survival (LFS) and survival. Amongst subjects achieving complete remission those with IKZF1 deletion had similar 5-year non-relapse mortality (NRM) (11% [2-20%] vs. 16% [4-28%]; P = 0.736), a higher 5-year cumulative incidence of relapse (CIR) (55% [35-76%] vs. 25% [12-38%]; P = 0.004), and worse 5-year leukemia-free survival (LFS) (33% [16-52%] vs. 59% [42-73%]; P = 0.012) and survival (48% [33-62%] vs. 75% [57-86%]; P = 0.002). In multivariate analyses IKZF1 deletion was associated with an increased relapse (relative risk [RR] =2.7, [1.4-5.2]; P = 0.002), a higher risk of treatment-failure (inverse of LFS; RR = 2.1, [1.2-3.6]; P = 0.007) and a higher risk of death (RR = 2.8, [1.5-5.5]; P = 0.002). The adverse impact of IKZF1 deletion on outcomes was stronger in subjects without vs. with BCR-ABL1 and in subjects receiving chemotherapy-only vs. an allotransplant. IKZF1 deletion was independently-associated with a higher relapse risk and worse LFS and survival in adults with common B-cell ALL after adjusting for other prognostic variables and differences in therapies. These data suggest IKZF1 deletion may be a useful prognostic variable in adults with common B-cell ALL, especially in persons without BCR-ABL1 and those receiving chemotherapy

    Purpose Higher doses of the anthracycline daunorubicin during induction therapy for acute myeloid leukemia (AML) have been shown to improve remission rates and survival. We hypothesized that improvements in outcomes in adult AML may be further achieved by increased anthracycline dose during consolidation therapy. Patients and Methods Patients with AML in complete remission after induction therapy were randomly assigned to receive two cycles of consolidation therapy with cytarabine 100 mg/m 2 daily for 5 days, etoposide 75 mg/m 2 daily for 5 days, and idarubicin 9 mg/m 2 daily for either 2 or 3 days (standard and intensive arms, respectively). The primary end point was leukemia-free survival (LFS). Results Two hundred ninety-three patients 16 to 60 years of age, excluding those with core binding factor AML and acute promyelocytic leukemia, were randomly assigned to treatment groups (146 to the standard arm and 147 to the intensive arm). Both groups were balanced for age, karyotypic risk, and FLT3-internal tandem duplication and NPM1 gene mutations. One hundred twenty patients in the standard arm (82%) and 95 patients in the intensive arm (65%) completed planned consolidation ( P < .001). Durations of severe neutropenia and thrombocytopenia were prolonged in the intensive arm, but there were no differences in serious nonhematological toxicities. With a median follow-up of 5.3 years (range, 0.6 to 9.9 years), there was a statistically significant improvement in LFS in the intensive arm compared with the standard arm (3-year LFS, 47% [95% CI, 40% to 56%] v 35% [95% CI, 28% to 44%]; P = .045). At 5 years, the overall survival rate was 57% in the intensive arm and 47% in the standard arm ( P = .092). There was no evidence of selective benefit of intensive consolidation within the cytogenetic or FLT3-internal tandem duplication and NPM1 gene mutation subgroups. Conclusion An increased cumulative dose of idarubicin during consolidation therapy for adult AML resulted in

    The aim of this chart review of adult patients treated for acute lymphoblastic leukemia (ALL) with total body irradiation (TBI) was to evaluate early and late toxicity and long-term outcome. A total of 110 adult patients (34 ± 12 years) with ALL underwent TBI (6 fractions of 2 Gy for a total of 12 Gy) as a part of the treatment regimen before transplantation. Treatment-related toxicity, mortality, and hematologic outcome are reported. Mean follow-up was 70 months. The 2- and 5-year leukemia-free survival rates were 78 and 72 %, respectively. In all, 29 % (32/110) patients suffered from medullary recurrence after a median time of 7 months. Gender was the only statistically significant prognostic factor in terms of overall survival in favor of female patients. Treatment-related mortality and overall survival after 2 and 5 years were 16 and 22 %, and 60 and 52.7 %, respectively. The most frequent late reaction wascGVHD of the skin (n = 33, 30 %). In addition, 15.5 % (17/110 patients) suffered pulmonary symptoms, and 6 patients developed lung fibrosis. Eyes were frequently affected by the radiation (31/110 = 28 %); 12 of 110 patients (11 %) presented with symptoms from osteoporosis, 5 of 110 patients (4.5 %) developed hypothyreosis and 2 patients diabetes mellitus. Of the male patients, 11 % reported erectile dysfunction or loss of libido, while 2 of 36 women reported menopausal syndrome at the mean time of 28 months after treatment with requirement for substitution. No women became pregnant after treatment. No acute or late cardiac toxicities were documented in our patients. No secondary malignancies were documented. Although hematologic outcome was in the upper range of that reported in the literature, treatment-related mortality (TRM) and medullary recurrences remain a challenge. Sophisticated radiation techniques allow for decreasing toxicity to certain organs and/or dose escalation to the bone marrow in highly selected patients in order to improve therapeutic

    Full Text Available Diet-induced obesity in rat pregnancy has been shown previously to be associated with consistently raised blood pressure in the offspring, attributed to sympathetic over-activation, but the relative contributions to this phenotype of maternal obesity versus raised dietary fat is unknown. Sprague-Dawley female rats were fed either a control (4.3% fat, n = 11 or lard-enriched (23.6% fat, n = 16 chow 10 days prior to mating, throughout pregnancy and lactation. In conscious adult (9-month-old offspring cardiovascular parameters were measured (radiotelemetry. The short period of fat-feeding did not increase maternal weight versus controls and the baseline blood pressure was similar in offspring of fat fed dams (OF and controls (OC. However, adult male OF showed heightened cardiovascular reactivity to acute restraint stress (p<0.01; Δ systolic blood pressure (SBP and Δheart rate (HR with a prolonged recovery time compared to male OC. α1/β-adrenergic receptor blockade normalised the response. Also, after dietary salt-loading (8%-NaCl ad libitum for 1 week male OF demonstrated higher SBP (p<0.05 in the awake phase (night-time and increased low/high frequency ratio of power spectral density of HR variability versus OC. Baroreflex gain and basal power spectral density components of the heart rate or blood pressure were similar in male OF and OC. Minor abnormalities were evident in female OF. Fat feeding in the absence of maternal obesity in pregnant rats leads to altered sympathetic control of cardiovascular function in adult male offspring, and hypertension in response to stressor stimuli.

    Highlights: • Low-level acute cadmium exposure elicited tissue-specific gene expression changes. • Molecular initiating events included oxidative stress and disruption of DNA repair. • Metallothionein, a marker of metal exposure, was not significantly affected. • We report effects of cadmium on cholesterol metabolism and steroid synthesis. • Diabetic complications and impaired reproduction are potential adverse outcomes. - Abstract: Cadmium is a heavy metal that can accumulate to toxic levels in the environment leading to detrimental effects in animals and humans including kidney, liver and lung injuries. Using a transcriptomics approach, genes and cellular pathways affected by a low dose of cadmium were investigated. Adult largemouth bass were intraperitoneally injected with 20 μg/kg of cadmium chloride (mean exposure level – 2.6 μg of cadmium per fish) and microarray analyses were conducted in the liver and testis 48 h after injection. Transcriptomic profiles identified in response to cadmium exposure were tissue-specific with the most differential expression changes found in the liver tissues, which also contained much higher levels of cadmium than the testis. Acute exposure to a low dose of cadmium induced oxidative stress response and oxidative damage pathways in the liver. The mRNA levels of antioxidants such as catalase increased and numerous transcripts related to DNA damage and DNA repair were significantly altered. Hepatic mRNA levels of metallothionein, a molecular marker of metal exposure, did not increase significantly after 48 h exposure. Carbohydrate metabolic pathways were also disrupted with hepatic transcripts such as UDP-glucose, pyrophosphorylase 2, and sorbitol dehydrogenase highly induced. Both tissues exhibited a disruption of steroid signaling pathways. In the testis, estrogen receptor beta and transcripts linked to cholesterol metabolism were suppressed. On the contrary, genes involved in cholesterol metabolism were highly

    Critical care practice guidelines identify a lack of clear evidence on the effectiveness of massage for pain control. To assess the effect of massage on acute pain in critically and acutely ill adults post-thoracic surgery. Medline, Embase, CINAHL, PsychInfo, Web of Science, Scopus and Cochrane Library databases were searched. Eligible studies were randomized controlled trials (RCTs) evaluating the effect of massage compared to attention control/sham massage or standard care alone on acute pain intensity post-thoracic surgery. Twelve RCTs were included. Of these, nine evaluated massage in addition to standard analgesia, including 2 that compared massage to attention control/sham massage in the intensive care unit (ICU), 6 that compared massage to standard analgesia alone early post-ICU discharge, and 1 that compared massage to both attention control and standard care in the ICU. Patients receiving massage with analgesia reported less pain (0-10 scale) compared to attention control/sham massage (3 RCTs; N = 462; mean difference -0.80, 95% confidence interval [CI] -1.25 to -0.35; p Massage, in addition to pharmacological analgesia, reduces acute post-cardiac surgery pain intensity.

    Studies have demonstrated superior outcomes for adolescent and young adult (AYA) patients with acute lymphoblastic leukemia (ALL) who are treated using pediatric versus adult therapeutic regimens. To the best of our knowledge, whether adult oncologists in the United States have adopted this approach to ALL in AYA patients is currently unknown. The objective of the current study was to provide a population-based description of ALL treatment patterns in AYA individuals over the past decade. Data regarding AYA patients aged 15 to 39 years and diagnosed with ALL between 2004 and 2014 while living in the Greater Bay Area were obtained from the Greater Bay Area Cancer Registry (GBACR). Treating facilities were designated as pediatric or adult centers; induction treatment regimens were abstracted from registry text data fields. Of 304 patients diagnosed in the GBACR catchment region, complete treatment data were available for 229 (75%). The location of care was identified for 296 patients (97%) treated at 31 unique centers. Approximately 70% of AYA patients received induction therapy at an adult treatment center. All AYA patients who were treated at pediatric centers received pediatric ALL regimens. Among AYA patients treated by adult oncologists with complete treatment data, none received a pediatric regimen before 2008. Between 2008 and 2012, while the US Adult Intergroup C10403 pediatric-inspired ALL protocol was open to accrual, 31% of AYA patients treated by adult oncologists received pediatric regimens. This rate fell to 21% from 2013 through 2014. Adult facilities treating ≥ 2 AYA patients with ALL per year captured in the GBACR were more likely to administer pediatric regimens than lower volume centers (P = .03). As of 2014, only a minority of AYA patients with ALL received pediatric ALL regimens at adult cancer centers. Cancer 2017;122-130. © 2016 American Cancer Society. © 2016 American Cancer Society.

    Full Text Available Background: With appearance of nano particles as an important component in modern medicine, and considering to new properties of these components, study of their effects on human health is essential. Since zinc components influences mechanisms of nociception, the aim of this study was to evaluate the effect of nano zinc oxide as a new source of zinc and important components in pharmaceutical and hygienic cosmetic production on nociception in adult female rats. Materials and Methods: Female rats were divided into groups: control (receiving saline 0.9% and receiving nano ZnO (0.5, 1, and 5 mg/kg. Hot plate and tail flick tests as models of somatic acute pain were used for evaluation of the pain. The mean of latency time in paw licking and tail withdrawal respectively recorded as nociception indexes in each test for every animal. The animal numbers in each group was seven. Results: In tail flick test, nano ZnO (0.5, 1 mg/kg and in the hot plate test in dose of 0.5 mg/kg, induces significant analgesia (p<0.05 and with increasing of dose reduced its analgesic effect. Conclusion: It seems nano ZnO inhibit the nociception mechanisms and these analgesic properties are more efficient in the low doses. Probably by increasing dose of nano particles aggregation phenomenon prevent of anti-nociception effects of nano ZnO.

    Acute myeloid leukemia (AML) is an acquired clonal frequent malignant disorder of myeloid progenitor cells. Our aim was to study demographical and clinicopathological features of adult Pakistani AML patients at presentation. In this single centre study extending from January 2010 to December 2014, data were retrieved from the patient records with a predetermined performa and analyzed with SPSS version 22. Overall 125 patients were diagnosed at our institution with de novo AML during the study period. There were 76 males and 49 females (ratio 1.5:1), with an age range between 15 and 85 years and a mean age of 38.8±20.1 years. The major complaints were fever (72.8%), generalized weakness (60%), bleeding (37.6%) and dyspnea (12%). Physical examination revealed pallor in 56.8%, splenomegaly and hepatomegaly in 16% and 12.8%, respectively, and lymphodenopathy in 10.4%. The mean hemoglobin was 8.19±2.12g/dl with a mean MCV of 86.0±9.83 fl, a mean total leukocyte count of 43.1±68.5x109/l, an ANC of 3.09±6.66x109/l and a mean platelet count of 62.3±78.6x109/l. AML in Pakistani patients is seen in a relatively very young population with male preponderance, compared with the west. However, clinico-pathological features appear comparable to published data.

    Acute appendicitis is the most common abdominal surgical emergency in the United States, with a lifetime risk of 7%-8%. The treatment paradigm for complicated appendicitis has evolved over the past decade, and many cases now are managed by broad-spectrum antibiotics. We determined the role of non-operative and operative management in adult patients with uncomplicated appendicitis. Several meta-analyses have attempted to clarify the debate. Arguably the most influential is the Appendicitis Acuta (APPAC) Trial. According to the non-inferiority analysis and a pre-specified non-inferiority margin of -24%, the APPAC did not demonstrate non-inferiority of antibiotics vs. appendectomy. Significantly, however, the operations were nearly always open, whereas the majority of appendectomies in the United States are done laparoscopically; and laparoscopic and open appendectomies are not equivalent operations. Treatment with antibiotics is efficacious more than 70% of the time. However, a switch to an antimicrobial-only approach may result in a greater probability of antimicrobial-associated collateral damage, both to the host patient and to antibiotic susceptibility patterns. A surgery-only approach would result in a reduction in antibiotic exposure, a consideration in these days of focus on antimicrobial stewardship. Future studies should focus on isolating the characteristics of appendicitis most susceptible to antibiotics, using laparoscopic operations as controls and identifying long-term side effects such as antibiotic resistance or Clostridium difficile colitis.

    Full Text Available In animals, physical activity has been shown to induce functional and structural changes especially in the hippocampus and to improve memory, probably by upregulating the release of neurotrophic factors. In humans, results on the effect of acute exercise on memory are inconsistent so far. Therefore, the aim of the present study was to assess the effects of a single bout of physical exercise on memory consolidation and the underlying neuroendocrinological mechanisms in young adults. Participants encoded a list of German-Polish vocabulary before exercising for 30 minutes with either high intensity or low intensity or before a relaxing phase. Retention of the vocabulary was assessed 20 minutes after the intervention as well as 24 hours later. Serum BDNF and salivary cortisol were measured at baseline, after learning, and after the intervention. The high-intensity exercise group showed an increase in BDNF and cortisol after exercising compared to baseline. Exercise after learning did not enhance the absolute number of recalled words. Participants of the high-intensity exercise group, however, forgot less vocabulary than the relaxing group 24 hours after learning. There was no robust relationship between memory scores and the increase in BDNF and cortisol, respectively, suggesting that further parameters have to be taken into account to explain the effects of exercise on memory in humans.

    The use of psychotropic drugs in clinical and translational brain research continues to grow, and the need for novel experimental models and screens is becoming widely recognized. Mounting evidence supports the utility of zebrafish (Danio rerio) for studying various pharmacological manipulations, as an alternative model complementing the existing rodent paradigms in this field. Here, we explore the effects of acute 20-min exposure to two commonly abused psychotropic compounds, Δ(9)-tetrahydrocannabinol (THC) and heroin, on adult zebrafish behavior in the novel tank test. Overall, THC administration (30 and 50 mg/L) produces an anxiogenic-like reduction of top swimming, paralleled with a slower, continuous bottom swimming. In contrast, heroin exposure (15 and 25 mg/L) evoked a hyperlocomotor response (with rapid bouts of bottom swimming and frequent 'bouncing' motions) without altering anxiety-sensitive top/bottom endpoints. The behavioral effects of these two compounds in zebrafish seem to parallel the respective rodent and human findings. Collectively, this emphasizes the growing significance of novel emerging aquatic models in translational drug abuse research and small molecule screening. © 2013 Elsevier B.V. All rights reserved.

    Full Text Available Litopenaeus vannamei is one of the most commercially important species of shrimp in the world. In this study, we performed acute hypoxia tests with Litopenaeus vannamei to estimate 12 h median lethal concentration (LC50 values at different life stages. The results indicated that the 12 h LC50 values were significantly different in different life stages of shrimp (P<0.05. The maximum value of 12 h LC50 was 2.113 mg L−1 for mysis III, and the minimum value was 0.535 mg L−1 for adult shrimp with an average total length of 6 cm. The study also determined the hemocyanin concentration (HC and the total hemocyte counts (THC in the conditions of hypoxia and reoxygenation. These results showed that the THC decreased and the HC increased under hypoxia, and the THC increased and the HC decreased in the condition of reoxygenation. These results can provide fundamental information for shrimp farming and seedling and also can guide the breeding selection, as well as being very helpful to better understand the hypoxia stress mechanism of shrimp.

    Objective was to assess the circulating rotavirus strains among hospitalized children and adults in Gizan City. This cross-sectional study was based in 5 hospitals in the Gizan area. Stool samples were collected between November 2004 and March 2005 from sequential patients with acute dehydrating diarrhea. Rotavirus antigen was detected in stool by enzyme-linked immunosorbent assay. The diversity of rotavirus strains was investigated using electropherotyping and reverse transcription-polymerase chain reaction amplification of the VP7 and VP4 genes (G and P genotyping). Rotavirus was detected in 54 of 454 (12%) subjects. The ages of those infected with rotavirus ranged from 15 days to 20 years, with a median age of 36 months. The highest rotavirus detection rate (24%) occurred in children in aged 48-59 months. Overall, 50 (93%) of strains could be assigned both a G- and P- type; G1P (8) was the most frequently detected strain type (n=48, 89%) with one rotavirus each of G2P (4) and G9P (8). Rotavirus strains circulating in Gizan would be well covered by current rotavirus vaccines. Rotavirus serotype G9 has been detected in Saudi Arabia for the first time. Continued surveillance of rotavirus strains is required. (author)

    Acute poisoning continues to be an important public health problem. Medical records of 116 adult patients presented to Tikur Anbessa Specialized University Hospital from January 2007 to December 2008 were reviewed retrospectively. Females outnumbered males. Mean age was 21 years. Most (96.5%) were intentional self-harm poisonings. Household cleansing agents were the leading causes of poisoning (43.1%) followed by organophosphate (21.6%) and phenobarbitone (10.3%). Loss of consciousness, vomiting and epigastric pain were the common presenting features accounting 46.2%, 23.8% and 22.5%, respectively. A total of 13(11.2%) patients had already known mental illness and 12 of them poisoned by using their own medications. Among 65 patients who reported their reason of poisoning, temporary quarrel (57%) and emotional disturbance (26%) were frequently cited. The case fatality rate was 8.6%. Death was most occurred by organophosphate (5/25) and phenobarbitone poisoning (3/12). Awareness on proper handling of chemicals and prescribed agents should be forwarded to users of these agents. Majority of patients poisoned for intentional self-harm purposes so that linkage of suicidal patients to appropriate mental health service is recommended. The availability of psychiatry consultation in the hospital is also recommended.

    This review examined effects of structured exercise (aerobic walking, with or without complementary modes of exercise) on cardiorespiratory measures, mobility, functional status, healthcare utilization, and Quality of Life in older adults (≥60 years) hospitalized for acute medical illness. Inclusion required exercise protocol, at least one patient-level or utilization outcome, and at least one physical assessment point during hospitalization or within 1 month of intervention. MEDLINE, Embase, and CINAHL databases were searched for studies published from 2000 to March 2015. Qualitative synthesis of 12 articles, reporting on 11 randomized controlled (RCT) and quasi-experimental studies described a heterogeneous set of exercise programs and reported mixed results across outcome categories. Methodological quality was independently assessed by 2 reviewers using the Cochrane Collaboration Risk of Bias tool. Larger, well-designed RCTs are needed, incorporating measurement of pre-morbid function, randomization with intention-to-treat analysis, examination of a targeted intervention with pre-defined intensity, and reported adherence and attrition.

    Myelodysplastic syndrome (MDS) is a clonal blood disorder characterized by ineffective hematopoiesis, cytopenias, dysplasia and an increased risk of acute myeloid leukemia (AML). With the growing availability of clinical genetic testing, there is an increasing appreciation that a number of genetic predisposition syndromes may underlie apparent de novo presentations of MDS/AML, particularly in children and young adults. Recent findings of clonal hematopoiesis in acquired aplastic anemia add another facet to our understanding of the mechanisms of MDS/AML predisposition. As more predisposition syndromes are recognized, it is becoming increasingly important for hematologists and oncologists to have familiarity with the common as well as emerging syndromes, and to have a systematic approach to diagnosis and screening of at risk patient populations. Here, we provide a practical algorithm for approaching a patient with a suspected MDS/AML predisposition, and provide an in-depth review of the established and emerging familial MDS/AML syndromes caused by mutations in the ANKRD26, CEBPA, DDX41, ETV6, GATA2, RUNX1, SRP72 genes. Finally, we discuss recent data on the role of somatic mutations in malignant transformation in acquired aplastic anemia, and review the practical aspects of MDS/AML management in patients and families with predisposition syndromes.

    This review is an update of "Single dose oral ketoprofen and dexketoprofen for acute postoperative pain in adults" last updated in Issue 4, 2009. Ketoprofen is a non-selective nonsteroidal anti-inflammatory drug (NSAID) used to treat acute and chronic painful conditions. Dexketoprofen is the (S)-enantiomer, which is believed to confer analgesia. Theoretically dexketoprofen is expected to provide equivalent analgesia to ketoprofen at half the dose, with a consequent reduction in gastrointestinal adverse events. This review is one of a series on oral analgesics for acute postoperative pain. Individual reviews have been brought together in two overviews to provide information about the relative efficacy and harm of the different interventions. To assess the efficacy and safety of single dose oral ketoprofen and oral dexketoprofen compared with placebo for acute postoperative pain, using methods that permit comparison with other analgesics evaluated in the same way, and criteria of efficacy recommended by an in-depth study at the individual patient level. For this update, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase from 2009 to 28 March 2017. We also searched the reference lists of retrieved studies and reviews, and two online clinical trial registries. Randomised, double-blind, placebo-controlled trials of single dose orally administered ketoprofen or dexketoprofen in adults with moderate to severe acute postoperative pain. Two review authors independently considered studies for inclusion in the review, examined issues of study quality and potential bias, and extracted data. For dichotomous outcomes, we calculated risk ratio (RR) and number needed to treat for an additional beneficial outcome (NNT) or harmful outcome (NNH) with 95% confidence intervals (CI) for ketoprofen and dexketoprofen, compared with placebo, where there were sufficient data. We collected information on the number of participants with at least 50

    Nitrofurantoin remains a key oral antibiotic stewardship program (ASP) option in the treatment of acute uncomplicated cystitis (AUC) due to multi-drug resistant (MDR) Gram negative bacilli (GNB). However, there have been concerns regarding decreased nitrofurantoin efficacy with renal insufficiency. In our experience over the past three decades, nitrofurantoin has been safe and effective in treating AUC in hospitalized adults with renal insufficiency. Accordingly, we retrospectively reviewed our recent experience treating AUC in hospitalized adults with decreased renal function (CrCl renal insufficiency (CrCl renal insufficiency, i.e., CrCl renal insufficiency (CrCl < 30 ml/ml).

The primary outcome was any major cardiovascular event (composite of cardiovascular mortality, acute coronary syndrome, or ischemic stroke) within 1 year following treatment initiation. Cox regression was used to estimate hazard ratios (HRs) while on current antipsychotic monotherapy...... atypical antipsychotics in young and middle-aged adults. METHODS: We conducted a nationwide register-based cohort study in Denmark, 1997-2011, including adults aged 18-64 years, who started treatment with oral or intramuscular olanzapine (n = 15,774), oral quetiapine (n = 18,717), and oral or intramuscular.......9 to 2.0) events for quetiapine. CONCLUSIONS: Among young and middle-aged outpatients, the risk of acute major cardiovascular events was similar with use of olanzapine, quetiapine, and risperidone. Although moderate relative differences cannot be ruled out, any differences are small in absolute terms....

    The radioimmunoassay (RIA) and counterimmunoelectrophoretic (CIE) methods were compared in detecting hepatitis B antigen (HB/sub s/Ag) in 407 acute and 336 convalescent sera of adults with viral hepatitis. The CIE method demonstrated that 41 percent of acute and 28 percent of 14- to 17-day serum specimens were HB/sub s/Ag-positive. The RIA method demonstrated seropositivity in 60 percent of acute and 56 percent of convalescent specimens (P less than .001). Eighty-four percent of coded specimens initially positive for HB/sub s/Ag by RIA were found to have subtype antigenic determinants d or y; 92 percent of the HB/sub s/Ag-negative controls were negative for subtype antigens, confirming the specificity of the RIA test. RIA subtyping data corroborated earlier work with immunodiffusion techniques. (U.S.)

    Evaluate the diagnostic accuracy of the APPY1TM biomarker panel, previously described for use in pediatric patients, for identifying adult ED patients with abdominal pain who are at low risk of acute appendicitis. This study prospectively enrolled subjects >18years of age presenting to seven U.S. emergency departments with pain suggesting possible acute appendicitis. The APPY1 panel was performed on blood samples drawn from each patient at the time of initial evaluation and results were correlated with the final diagnosis either positive or negative for acute appendicitis. 431 patients were enrolled with 422 completing all aspects of the study. The APPY1 biomarker panel exhibited a sensitivity of 97.5% (95% CI, 91.3-99.3%), a negative predictive value of 98.4% (95% CI, 94.4-99.6%), a negative likelihood ratio of 0.07 (95% CI, 0.02-0.27), with a specificity of 36.5% (95% CI, 31.6-41.8%) for acute appendicitis. The panel correctly identified 125 of 342 (36.6%) patients who did not have appendicitis with 2 (2.5%) false negatives. The CT utilization rate in this population was 72.7% (307/422). Of 307 CT scans, 232 were done for patients who did not have appendicitis and 79 (34%) of these patients were correctly identified as negative with "low risk" biomarker panel results, representing 26% (79/307) of all CT scans performed. This biomarker panel exhibited high sensitivity and negative predictive value for acute appendicitis in this prospective adult cohort, thereby potentially reducing the dependence on CT for the evaluation of possible acute appendicitis.

    To compare rate of acute stress disorder (ASD) and intensity of acute stress symptoms (ASS) in younger, middle-aged and older Israeli citizens exposed to missile attacks during the second Lebanon war. A telephone survey of a random sample of residents in the northern area of Israel was conducted in July 2006, during the third week of Lebanon war. Respondents were divided into groups aged 18-40, 41-69 and 70+. ASD and ASS were measured by the Acute Stress Interview questionnaire and by war-related exposure variables and demographic data. Exposure variables were similar in the three age groups. Older respondents reported lower intensity of ASS and obtained lower means for each of the symptoms criteria than the young adults, while the middle-aged adults were in between the younger and the older group. ASD criteria were met by 13.2% of the younger, 4.7% of middle-aged and 4.3% of older respondents (p > 0.05), and subsyndromal ASD was found in 20.5%, 14.1% and 4.4% (p war situation with lower level of acute stress symptoms. Long-term effects of war on different age groups should be further studied.

  4. Consideration of QRS complex in addition to ST-segment abnormalities in the estimation of the "risk region" during acute anterior or inferior myocardial infarction.

    The myocardial area at risk (MaR) is an important aspect in acute ST-elevation myocardial infarction (STEMI). It represents the myocardium at the onset of the STEMI that is ischemic and could become infarcted if no reperfusion occurs. The MaR, therefore, has clinical value because it gives an indication of the amount of myocardium that could potentially be salvaged by rapid reperfusion therapy. The most validated method for measuring the MaR is (99m)Tc-sestamibi SPECT, but this technique is not easily applied in the clinical setting. Another method that can be used for measuring the MaR is the standard ECG-based scoring system, Aldrich ST score, which is more easily applied. This ECG-based scoring system can be used to estimate the extent of acute ischemia for anterior or inferior left ventricular locations, by considering quantitative changes in the ST-segment. Deviations in the ST-segment baseline that occur following an acute coronary occlusion represent the ischemic changes in the transmurally ischemic myocardium. In most instances however, the ECG is not available at the very first moments of STEMI and as times passes the ischemic myocardium becomes necrotic with regression of the ST-segment deviation along with progressive changes of the QRS complex. Thus over the time course of the acute event, the Aldrich ST score would be expected to progressively underestimate the MaR, as was seen in studies with SPECT as gold standard; anterior STEMI (r=0.21, p=0.32) and inferior STEMI (r=0.17, p=0.36). Another standard ECG-based scoring system is the Selvester QRS score, which can be used to estimate the final infarct size by considering the quantitative changes in the QRS complex. Therefore, additional consideration of the Selvester QRS score in the acute phase could potentially provide the "component" of infarcted myocardium that is missing when the Aldrich ST score alone is used to determine the MaR in the acute phase, as was seen in studies with SPECT as gold

    Full Text Available Acute respiratory infections (ARI are the most common infectious diseases affecting all age groups, but primarily children under 5 years, adults older than 65 years or people with risk factors and serious chronic processes that increase the risk of complications and severe forms of the disease. According to the WHO, in its Bulletin N°310 dated May 2014, infections of the lower respiratory tract were one of the 10 causes of death in the world in 2012. In the U.S., the rate of death from influenza and its complications averages 20 thousand people annually, and the direct costs of treatment of patients with influenza is 1–3 billion dollars, indirect — 10–15 billion a year. In Ukraine, every year ARI hurts 10–14 million individuals, accounting for 25–30 % of the total and approximately 75–90 % of infections in the country. Diseases caused by influenza viruses are not more than 8 %. During periods of epidemic rise (in the winter, the peak is mainly observed in February, this figure rises to 25 %. During the epidemic season 2014–2015, ARI affected 3 million 700 thousand people, which was 9.1 % of the total population. The economic damage from the flu is around 400 millions UAH a year. Losses only from a single case of influenza in the country are estimated at the equivalent of $100 (including the costs of temporary incapacity for work, expenses for treatment of complications and the organization of anti-epidemic measures. In acute rhinosinusitis (ARI and ­others, individual and epidemiological approaches of the physician should be combined within his “medical science and professional art”. After conducting a differential diagnosis, the physician decides on the issues related to the admission of the patient to the hospital, consultation to the otolaryngologist, to the outpatient examination (laboratory and instrumental, etc. On the basis of such voluminous and necessary information and recommended base today, “independence and

    Acute exercise can positively impact cognition. The present study examined the effect of acute high-intensity aerobic exercise on prefrontal-dependent cognitive performance and brain-derived neurotrophic factor (BDNF). Fifty-eight young adults were randomly assigned to one of two experimental groups: (a) an acute bout of high-intensity exercise (n=29) or (b) a non-exercise control (n=29). Participants in the exercise group improved performance on inhibitory control in Stroop interference and on cognitive flexibility in Trail Making Test (TMT) Part-B compared with participants in the control group and increased BDNF immediately after exercise. There was a significant relationship between BDNF and TMT Part-B on the pre-post change following exercise. These findings provide support for the association between improved prefrontal-dependent cognitive performance and increased BDNF in response to acute exercise. We conclude that the changes in BDNF concentration may be partially responsible for prefrontal-dependent cognitive functioning following an acute bout of exercise.

    Access to diagnosis and dialysis for acute kidney injury can be life-saving, but can be prohibitively expensive in low-income settings. The burden of acute kidney injury in sub-Saharan Africa is presumably high but remains unknown. We did a systematic review to assess outcomes of acute kidney injury in sub-Saharan Africa and identify barriers to care. We searched PubMed, African Journals Online, WHO Global Health Library, and Web of Science for articles published between Jan 1, 1990, and Nov 30, 2014. We scored studies, and all were of medium-to-low quality. We made a pragmatic decision to include all studies to best reflect reality, and did a descriptive analysis of extracted data. This study is registered with PROSPERO, number CRD42015015690. We identified 3881 records, of which 41 met inclusion criteria, including 1403 adult patients and 1937 paediatric patients. Acute kidney injury in sub-Saharan Africa is severe, with 1042 (66%) of 1572 children and 178 (70%) 253 of adults needing dialysis in studies reporting dialysis need. Only 666 (64%) of 1042 children (across 11 studies) and 58 (33%) of 178 adults (across four studies) received dialysis when needed. Overall mortality was 34% in children and 32% in adults, but rose to 73% in children and 86% in adults when dialysis was needed but not received. Major barriers to access to care were out-of-pocket costs, erratic hospital resources, late presentation, and female sex. Patients in these studies are those with resources to access care. In view of overall study quality, data interpretation should be cautious, but high mortality and poor access to dialysis are concerning. The global scarcity of resources among patients and health centres highlights the need for a health-system-wide approach to prevention and management of acute kidney injury in sub-Saharan Africa.

    Full Text Available This review focuses on the most recent advances in the diagnostic and prognostic work-up of adult acute lymphoblastic leukemia (ALL, and on their implications in the clinical management of the disease. Over the years, information obtained through extensive immunophenotyping, karyotyping, molecular genetics, multidrug resistance and, more recently, genomic profiling is progressively contributing to a better understanding of the biology of this complex disease, to the identification of subgroups of patients with different clinical outcomes, to a more precise monitoring of minimal residual disease, to the use of different therapeutic protocols based on prognostic indicators and, finally, to the design of innovative and specific treatment strategies. The next few years will tell us if this biologically-guided approach, which is progressively individualizing the management of adult ALL patients, will ultimately impact on the prognosis of a disease that has stagnated over many decade.Esta revisão focaliza os mais recentes avanços no diagnóstico e prognóstico da leucemia linfoblástica aguda do adulto e suas implicações no manuseio clínico desta doença. Com o passar dos anos, informações obtidas através de extensa pesquisa em imunofenotipagem, citogenética, genética molecular, resistência a múltiplas drogas e, mais recentemente, perfil genômico têm contribuído progressivamente para o melhor entendimento da biologia desta doença complexa, na identificação de sub grupos de pacientes com evolução clínica distintas, no mais preciso monitoramento da doença residual mínima, no uso de diferentes protocolos baseados em indicadores prognósticos e, mais recentemente, também no desenho de tratamentos inovativos e específicos.

    Recruitment manoeuvres involve transient elevations in airway pressure applied during mechanical ventilation to open ('recruit') collapsed lung units and increase the number of alveoli participating in tidal ventilation. Recruitment manoeuvres are often used to treat patients in intensive care who have acute respiratory distress syndrome (ARDS), but the effect of this treatment on clinical outcomes has not been well established. This systematic review is an update of a Cochrane review originally published in 2009. Our primary objective was to determine the effects of recruitment manoeuvres on mortality in adults with acute respiratory distress syndrome.Our secondary objective was to determine, in the same population, the effects of recruitment manoeuvres on oxygenation and adverse events (e.g. rate of barotrauma). For this updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (OVID), Embase (OVID), the Cumulative Index to Nursing and Allied Health Literature (CINAHL, EBSCO), Latin American and Caribbean Health Sciences (LILACS) and the International Standard Randomized Controlled Trial Number (ISRCTN) registry from inception to August 2016. We included randomized controlled trials (RCTs) of adults who were mechanically ventilated that compared recruitment manoeuvres versus standard care for patients given a diagnosis of ARDS. Two review authors independently assessed trial quality and extracted data. We contacted study authors for additional information. Ten trials met the inclusion criteria for this review (n = 1658 participants). We found five trials to be at low risk of bias and five to be at moderate risk of bias. Six of the trials included recruitment manoeuvres as part of an open lung ventilation strategy that was different from control ventilation in aspects other than the recruitment manoeuvre (such as mode of ventilation, higher positive end-expiratory pressure (PEEP) titration and lower tidal volume or plateau

    Background Migraine is a common, disabling condition and a burden for the individual, health services and society. Many sufferers choose not to, or are unable to, seek professional help and rely on over-the-counter (OTC) analgesics. Diclofenac is an established analgesic, and new formulations using the potassium or epolamine salts, which can be dissolved in water, have been developed for rapid absorption, which may be beneficial in acute migraine. Co-therapy with an antiemetic should help to reduce the nausea and vomiting commonly associated with migraine. Objectives To determine the efficacy and tolerability of diclofenac, alone or in combination with an antiemetic, compared to placebo and other active interventions in the treatment of acute migraine headaches in adults. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, ClinicalTrials.gov, and reference lists for studies through 27 September 2011. Selection criteria We included randomised, double-blind, placebo- and/or active-controlled studies using self administered diclofenac to treat a migraine headache episode, with at least 10 participants per treatment arm. Data collection and analysis Two review authors independently assessed trial quality and extracted data. We used numbers of participants achieving each outcome to calculate relative risk (or ‘risk ratio’) and numbers needed to treat to benefit (NNT) or harm (NNH) compared to placebo or a different active treatment. Main results Five studies (1356 participants) compared oral diclofenac with placebo, and one also compared it with sumatriptan; none combined diclofenac with a self administered antiemetic. Four studies treated attacks with single doses of medication, and two allowed an optional second dose for inadequate response. Only two studies, with three active treatment arms, provided data for pooled analysis of primary outcomes. For single doses of diclofenac

    There is good evidence that combining two different analgesics in fixed doses in a single tablet can provide better pain relief in acute pain and headache than either drug alone, and that the drug-specific benefits are essentially additive. This appears to be broadly true in postoperative pain and migraine headache across a range of different drug combinations, and when tested in the same and different trials. Adding caffeine to analgesics also increases the number of people obtaining good pain relief. Combinations of ibuprofen and caffeine are available without prescription in some parts of the world. To assess the analgesic efficacy and adverse effects of a single oral dose of ibuprofen plus caffeine for moderate to severe postoperative pain, using methods that permit comparison with other analgesics evaluated in standardised trials using almost identical methods and outcomes. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the Oxford Pain Relief Database, two clinical trial registries, and the reference lists of articles. The date of the most recent search was 1 February 2015. Randomised, double-blind, placebo- or active-controlled clinical trials of single dose oral ibuprofen plus caffeine for acute postoperative pain in adults. Two review authors independently considered trials for inclusion in the review, assessed risk of bias, and extracted data. We used the area under the pain relief versus time curve to derive the proportion of participants with at least 50% pain relief over six hours prescribed either ibuprofen plus caffeine or placebo. We calculated the risk ratio (RR) and number needed to treat to benefit (NNT). We used information on the use of rescue medication to calculate the proportion of participants requiring rescue medication and the weighted mean of the median time to use. We also collected information on adverse effects. We identified five randomised, double-blind studies with 1501 participants, but

  13. A new adult appendicitis score improves diagnostic accuracy of acute appendicitis - a prospective study

    Science.gov (United States)

    2014-01-01

    Background The aim of the study was to construct a new scoring system for more accurate diagnostics of acute appendicitis. Applying the new score into clinical practice could reduce the need of potentially harmful diagnostic imaging. Methods This prospective study enrolled 829 adults presenting with clinical suspicion of appendicitis, including 392 (47%) patients with appendicitis. The collected data included clinical findings and symptoms together with laboratory tests (white cell count, neutrophil count and C-reactive protein), and the timing of the onset of symptoms. The score was constructed by logistic regression analysis using multiple imputations for missing values. Performance of the constructed score in patients with complete data (n = 725) was compared with Alvarado score and Appendicitis inflammatory response score. Results 343 (47%) of patients with complete data had appendicitis. 199 (58%) patients with appendicitis had score value at least 16 and were classified as high probability group with 93% specificity.Patients with score below 11 were classified as low probability of appendicitis. Only 4% of patients with appendicitis had a score below 11, and none of them had complicated appendicitis. In contrast, 207 (54%) of non-appendicitis patients had score below 11. There were no cases with complicated appendicitis in the low probability group. The area under ROC curve was significantly larger with the new score 0.882 (95% CI 0.858 – 0.906) compared with AUC of Alvarado score 0.790 (0.758 – 0.823) and Appendicitis inflammatory response score 0.810 (0.779 – 0.840). Conclusions The new diagnostic score is fast and accurate in categorizing patients with suspected appendicitis, and roughly halves the need of diagnostic imaging. PMID:24970111

    Objective To investigate the blood pressure (BP) responses to cardiovascular stress test after a combined exercise circuit session at moderate intensity. Method Twenty individuals (10 male/10 fem; 33.4± 6.9 years; 70.2± 15.8 kg; 170.4± 11.5 cm; 22.3± 6.8% body fat) were randomized in a different days to control session with no exercise or exercise session consisting of 3 laps of the following circuit: knee extension, bench press, knee flexion, rowing in the prone position, squats, shoulder press, and 5 min of aerobic exercise at 75-85% of age-predicted maximum heart rate and/or 13 on the Borg Rating of Perceived Exertion [scale of 6 to 20]. The sets of resistance exercise consisted of 15 repetitions at ~50% of the estimated 1 repetition maximum test. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at rest and during 1h of recovery in both experimental sessions. After that, blood pressure reactivity (BPR) was evaluated using the Cold Pressor Test. Results During 1h of exercise recovery, there was a reduction in SBP (3-6 mmHg) and DBP (2-5 mmHg) in relation to pre-session rest (p<0.01), while this reduction was not observed in the control session. A decline in BPR (4-7 mmHg; p<0.01) was observed 1h post-exercise session, but not in the control session. Post-exercise reductions in SBP and DBP were significantly correlated with BPR reductions (r=0.50-0.45; p<0.05). Conclusion A combined exercise circuit session at moderate intensity promoted subsequent post-exercise hypotension and acutely attenuated BPR in response to a cardiovascular stress test. In addition, the post-exercise BP reduction was correlated with BPR attenuation in healthy adults of both genders. PMID:24675911

    Hypocellular acute myeloid leukemia (Hypo-AML) is a rare disease entity. Studies investigating the biological characteristics of hypo-AML have been largely lacking. We examined the clinical and biological characteristics, as well as treatment outcomes of hypo-AML in our institutes over a seven years period. We retrospectively analyzed data on 631 adult AML patients diagnosed according to the French-American-British (FAB) classification and WHO classification of tumors of haematopoietic and lymphoid tissue, including 43 patients with hypo-AML. Biological variables, treatment outcomes and follow-up data on hypo-AML patients were analyzed. Out of 631 AML patients, 47 (7.4%) were diagnosed as hypo-AML, out of which 43 patients were evaluable. Compared with non-hypocellular AML, hypo-AML patients tended to be older (P = 0.05), more likely to present with leukocytopenia (P < 0.01) and anterior hematological diseases (P = 0.02). The overall complete remission (CR) rate, disease free survival (DFS), and overall survival (OS) in hypo-AML patients were comparable to those in non-hypo AML patients. Twenty-seven (62.8%) patients with hypocellular AML were treated with the standard regimen of anthracyclines and cytarabine (XA) (associated CR rate: 51.9%; median OS: 7 months; median DFS: 6.5 months). Sixteen (37.2%) patients were treated with a priming regimen containing homoharringtonine, cytarabine and G-CSF (HAG) (associated CR rate: 81.25%; median OS: 16 months; median DFS: 16 months). The overall prognosis of hypo-AML was not inferior to that of non-hypo AML. HAG regimen might increase response rates and improve survival in hypo-AML patients.

    Combining two different analgesics in fixed doses in a single tablet can provide better pain relief than either drug alone in acute pain. This appears to be broadly true across a range of different drug combinations, in postoperative pain and migraine headache. A new combination of dexketoprofen (a nonsteroidal anti-inflammatory drug) plus tramadol (an opioid) has been tested in acute postoperative pain conditions. It is not yet licensed for use. This review is one of a series on oral analgesics for acute postoperative pain. Individual reviews have been brought together in two overviews to provide information about the relative efficacy and harm of the different interventions. To assess the analgesic efficacy and adverse effects of a single fixed-dose of oral dexketoprofen plus tramadol, compared with placebo, for moderate to severe postoperative pain in adults, using methods that permit comparison with other analgesics evaluated in standardised trials using almost identical methods and outcomes. A secondary objective was to compare the combination with the individual analgesics alone. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) via CRSO, MEDLINE via Ovid, and Embase via Ovid from inception to 31 May 2016. We also searched the reference lists of retrieved studies and reviews, and two online clinical trial registries. Randomised, double-blind trials of oral dexketoprofen plus tramadol administered as a single oral dose, for the relief of acute postoperative pain in adults, and compared to placebo. Two review authors independently considered trials for inclusion in the review, examined issues of study quality and potential bias, and extracted data. For dichotomous outcomes, we calculated risk ratio (RR) and number needed to treat for an additional beneficial outcome (NNT) for dexketoprofen plus tramadol, compared with placebo with 95% confidence intervals (CI). We collected information on the number of participants with at least 50% of

    To review the available literature on the diagnostic and predictive value of acute-phase reactants in adult undifferentiated peripheral inflammatory arthritis (UPIA) as an evidence base for generating multinational clinical practice recommendations in the 3e Initiative in Rheumatology. A systematic literature search was carried out using Medline, Embase, the Cochrane Library, and abstracts presented at the 2007 and 2008 meetings of the American College of Rheumatology and European League Against Rheumatism, searching for prognostic and diagnostic markers of acute-phase reactants in adult UPIA. Articles that fulfilled predefined inclusion criteria were systematically reviewed, and the quality was appraised. Likelihood ratios (LR), sensitivity, and specificity for diagnostic and prognostic outcomes were calculated. A total of 18 publications out of 3699 identified references were included in the review. Only a small number of studies with significant heterogeneity, including different outcome measures and different cutoff values, were eligible for review, so pooling data was not possible. Overall, LR showed poor diagnostic and prognostic performance for most investigated acute-phase reactants. Available data showed some value for erythrocyte sedimentation rate in establishing a diagnosis in patients with undifferentiated arthritis; some prognostic and diagnostic value for C-reactive protein; some prognostic value for plasma viscosity in predicting persistence of arthritis; and some diagnostic value for sulfhydryl levels and matrix metalloproteinase-3 in establishing a diagnosis of rheumatoid arthritis. There is little published evidence concerning the diagnostic and predictive value of acute-phase reactants in patients with UPIA. Studies were heterogeneous, and "undifferentiated arthritis" was not well defined or was equivocally defined. The role of acute-phase reactants in diagnosing and predicting outcome in patients presenting with undifferentiated arthritis is

    How do the various anatomical parts (modules) of the animal body evolve into very different integrated forms (integration) yet still function properly without decreasing the individual's survival? This long-standing question remains unanswered for multiple reasons, including lack of consensus about conceptual definitions and approaches, as well as a reasonable bias toward the study of hard tissues over soft tissues. A major difficulty concerns the non-trivial technical hurdles of addressing this problem, specifically the lack of quantitative tools to quantify and compare variation across multiple disparate anatomical parts and tissue types. In this paper we apply for the first time a powerful new quantitative tool, Anatomical Network Analysis (AnNA), to examine and compare in detail the musculoskeletal modularity and integration of normal and abnormal human upper and lower limbs. In contrast to other morphological methods, the strength of AnNA is that it allows efficient and direct empirical comparisons among body parts with even vastly different architectures (e.g. upper and lower limbs) and diverse or complex tissue composition (e.g. bones, cartilages and muscles), by quantifying the spatial organization of these parts-their topological patterns relative to each other-using tools borrowed from network theory. Our results reveal similarities between the skeletal networks of the normal newborn/adult upper limb vs. lower limb, with exception to the shoulder vs. pelvis. However, when muscles are included, the overall musculoskeletal network organization of the upper limb is strikingly different from that of the lower limb, particularly that of the more proximal structures of each limb. Importantly, the obtained data provide further evidence to be added to the vast amount of paleontological, gross anatomical, developmental, molecular and embryological data recently obtained that contradicts the long-standing dogma that the upper and lower limbs are serial homologues

  20. Safety, efficacy, and clinical utility of asparaginase in the treatment of adult patients with acute lymphoblastic leukemia

    Full Text Available Jamie Koprivnikar, James McCloskey, Stefan Faderl Division of Leukemia, John Theurer Cancer Center at Hackensack University Medical Center, Hackensack, NJ, USA Abstract: Adults with acute lymphoblastic leukemia (ALL are known to have inferior outcomes compared to the pediatric population. Although the reasons for this are likely manyfold, the agents utilized and the increased intensity of pediatric treatments compared to adult treatments are likely significant contributing factors. Asparaginase, an enzyme that converts asparagine to aspartic acid, forms the backbone of almost all pediatric regimens and works by depleting extracellular asparagine, which ALL cells are unable to synthesize. Asparaginase toxicities, which include hypersensitivity reactions, pancreatitis, liver dysfunction, and thrombosis, have hindered its widespread use in the adult population. Here, we review the toxicity and efficacy of asparaginase in adult patients with ALL. With the proper precautions, it is a safe and effective agent in the treatment of younger adults with ALL with response rates in the frontline setting ranging from 78% to 96%, compared to most trials showing a 4-year overall survival of 50% or better. The age cutoff for consideration of treatment with pediatric-inspired regimens is not clear, but recent studies show promise particularly in the adolescent and young adult population. New formulations of asparaginase are actively in development, including erythrocyte-encapsulated asparaginase, which is designed to minimize the toxicity and improve the delivery of the drug.

    Acute inversion injuries of the ankle are the most common sports accidents, accounting for approximately 10% of emergency room admissions. In up to 85%, an injury of the lateral collateral ligaments is observed. Classically, the assessment of these injuries has relied on clinical examination and radiographs, including stress views. The aim of our study was to correlate prospectively the findings of high-field 3 T MRI in acute ankle distortion with clinical outcome. During a 6-month period, 38 patients were prospectively included. MRI was performed within 48 h of trauma and clinical examination using a protocol consisting of axial T2-weighted and coronal and sagittal T1-weighted images and a sagittal proton density (PDw) sequence. Each ligament injury was graded on a three-point scale. Functional outcome was evaluated using the AOFAS ankle-hindfoot scale. In 24/38 patients (63.12%), ligament injury was observed. In 22/24 cases, this was an injury of the lateral ligaments and in 2/24 cases of the medial ligaments. Injury of the syndesmosis occurred in three patients, a bone bruise in four, and an osteochondral lesion in three cases. Patients with an injury of two or more ligaments or a bone bruise had a lower AOFAS score and returned to sports activities and full weight-bearing later (P < 0.01). MR imaging at 3 Tesla is an independent predictor for clinical outcome. Therefore MRI may be beneficial in those cases where the findings influence further treatment. (orig.)

    For adults with acute leukemia, it is important to know whether the therapeutic schemes initially planned were actually implemented. The European Group for Blood and Marrow transplantation Acute Leukemia Working Party prospectively followed 695 consecutive patients who were registered at the time of HLA typing. Of 304 patients with an available matched sibling donor (MSD), SCT was planned in 264, chemotherapy in 33 and autografting in 7. For the rest, an unrelated donor (UD) search was initiated in 198. Among these, 117 were transplanted, 114 received chemotherapy and 77 underwent autografting. Probabilities of receiving a planned treatment were 60 and 65% at 1 and 2 years, respectively. Patients scheduled to receive MSD SCT had an 82% probability, whereas those scheduled to undergo UD SCT had a 57% probability, of receiving their transplant at 1 year. The only factor associated with a lower probability of MSD SCT in first remission was delayed HLA typing (HR=0.82; P=0.03). One year after enrollment, 40% of patients did not follow their initial treatment plan. Because OS was 50% only at 3 years and only 57% of the patients without a MSD underwent SCT, this suggests room for improvement in outcomes for adults with acute leukemia.

    To discuss the clinical indications and complications of non-invasive ventilation. A review of articles published in peer-reviewed journals from 1966 to 1998 and identified through a MEDLINE search on non-invasive ventilation. Non-invasive ventilation (NIV) has been used in patients with respiratory failure caused by cardiogenic pulmonary oedema, acute respiratory distress syndrome, acute asthma and chronic obstructive pulmonary disease. However, in patients with acute respiratory failure, it appears that acute cardiogenic pulmonary oedema and acute respiratory failure associated with Pneumocystis carinii pneumonia are the only disorders in which significant benefits have been associated with the use of the NIV mode of CPAP. The potential clinical benefit of CPAP in acute asthma and blunt chest trauma remains unclear. Pressure support ventilation is beneficial in patients with hypercapnic acute respiratory failure (ARF) secondary to respiratory muscle insufficiency, high inspiratory work loads, or reduced alveolar ventilation. It appears also to be associated with an improved outcome in COPD patients with hypercapnic ARF. Non-invasive ventilation using the modes of CPAP, PSV, BiPAP and NIPPV should be considered in patients with respiratory disorders who remain in acute respiratory failure despite conventional therapy, before considering invasive mechanical ventilation.

    Two clinical trials suggest that procalcitonin-guided antibiotic therapy can safely reduce antibiotic prescribing in outpatient management of acute respiratory tract infections (ARTIs) in adults. Yet, it remains unclear whether procalcitonin testing is cost-effective in this setting. To evaluate the cost-effectiveness of procalcitonin-guided antibiotic therapy in outpatient management of ARTIs in adults. Cost-effectiveness model based on results from two published European clinical trials, with all parameters varied widely in sensitivity analyses. Two hypothetical cohorts were modeled in separate trial-based analyses: adults with ARTIs judged by their physicians to require antibiotics and all adults with ARTIs. Procalcitonin-guided antibiotic therapy protocols versus usual care. Costs and cost per antibiotic prescription safely avoided. We estimated the health care system willingness-to-pay threshold as $43 (range $0–$333) per antibiotic safely avoided, reflecting the estimated cost of antibiotic resistance per outpatient antibiotic prescribed. In the cohort including all adult ARTIs judged to require antibiotics by their physicians, procalcitonin cost $31 per antibiotic prescription safely avoided and the likelihood of procalcitonin use being favored compared to usual care was 58.4 % in a probabilistic sensitivity analysis. In the analysis that included all adult ARTIs, procalcitonin cost $149 per antibiotic prescription safely avoided and the likelihood of procalcitonin use being favored was 2.8 %. Procalcitonin-guided antibiotic therapy for outpatient management of ARTIs in adults would be cost-effective when the costs of antibiotic resistance are considered and procalcitonin testing is limited to adults with ARTIs judged by their physicians to require antibiotics.

    The increase in the older adult and oldest old population in Brazil is growing. This phenomenon may be accompanied by an increase in musculoskeletal symptoms such as low back pain. This condition is usually associated with disability. To verify the association between pain intensity and disability in older adults with acute low back pain and assess whether these variables differ depending on the age group and marital status. This is a cross-sectional study conducted with 532 older adults with acute low back pain episodes. Pain intensity was assessed through the Numeric Pain Scale and disability through the Late Life Function and Disability Instrument, which shows two dimensions: "frequency" and "limitation" in performing activities. The association between pain and disability was analyzed. For the interaction effect between age groups and marital status, we found that the oldest old living with a partner performed activities of the personal domain less often compared to the oldest old living alone. The oldest old group living with a partner had a lower frequency of performing activities, but did not report feeling limited. The association of pain with disability was minimal (rholow back pain was influenced by the interaction between age groups and marital status and is not associated with pain intensity.

    Falls in the older adults are a major public health concern. The growing population of adults 65 years or older, advances in medical care and changes in the costs of care motivated our study of the acute health care costs of fall-related injuries among the older adults in the United States of America. The Market Scan Medicare Supplemental database 1998 was used to estimate reimbursed costs for hospital, emergency department (ED), and outpatient clinic treatments for unintentional falls among older adults. A fall on the same level due to slipping, tripping, or stumbling was the most common mechanism of injury (28%). Mean hospitalisation cost was 17,483 US dollars(S.D.: 22,426 US dollars) in 2004 US dollars. Femur fracture was the most expensive type of injury (18,638 US dollars, S.D.: 19,990 US dollars). The mean reimbursement cost of an ED visit was 236 US dollars and 412 US dollars for an outpatient clinic visit. The magnitude of the economic and social costs of falls in older adults underscores the need for active research in the field of falls prevention.

    Adolescent and young adult (AYA) patients with cancer have not attained the same improvements in overall survival as either younger children or older adults. One possible reason for this disparity may be that the AYA cancers exhibit unique biologic characteristics, resulting in differences in clinical and treatment resistance behaviors. This report from the biologic component of the jointly sponsored National Cancer Institute and LiveStrong Foundation workshop entitled "Next Steps in Adolescent and Young Adult Oncology" summarizes the current status of biologic and translational research progress for 5 AYA cancers; colorectal cancer breast cancer, acute lymphoblastic leukemia, melanoma, and sarcoma. Conclusions from this meeting included the need for basic biologic, genomic, and model development for AYA cancers as well as translational research studies to elucidate any fundamental differences between pediatric, AYA, and adult cancers. The biologic questions for future research are whether there are mutational or signaling pathway differences (for example, between adult and AYA colorectal cancer) that can be clinically exploited to develop novel therapies for treating AYA cancers and to develop companion diagnostics. © 2016 American Cancer Society.

    This study was performed to determine if there is an age-related specificity in the response of muscle protein metabolism to severe burn injury during acute hospitalization. This is a retrospective analysis of previously published data. Nineteen adult and 58 pediatric burn-injured patients (age 43.3 ± 14.3 vs. 7.2 ± 5.3 years, adult vs. children) participated in stable isotope [ring-(2)H(5)]phenylalanine (Phe) infusion studies. Femoral arterial and venous blood samples and muscle biopsy samples were collected throughout the study. Data are presented as means ± standard deviation (SD). A p value less than 0.05 was considered statistically significant. Muscle net protein balance (NB) was higher in children (adult vs. children, -43 ± 61 vs. 8 ± 68 nmol Phe/min/100 ml leg volume, p 0.05); synthesis rate was 134 ± 96 and 192 ± 128 nmol Phe/min/100 ml leg volume in adults and children, respectively (p = 0.07). Age significantly correlated with muscle protein NB (p = 0.01) and FSR (p = 0.02); but not with breakdown (p = 0.67) and synthesis (p = 0.07) rates measured by using a three-pool model. In burn injury, the muscle protein breakdown may be affected to the same extent in adults and children, whereas synthesis may have age-related specificities, resulting in a better but still low NB in children.

    Age-related differences in sensitivity to the acute effects of alcohol may play an important role in the increased risk for the development of alcoholism seen in teens that begin drinking at an early age. The present study evaluated the acute and protracted (hangover) effects of ethanol in adolescent (P33-P40) and adult (P100-P107) Wistar rats, using the cortical electroencephalogram (EEG). Six minutes of EEG was recorded during waking, 15 min after administration of 0, 1.5, or 3.0 g/kg ethanol, and for 3 h at 20 h post ethanol, during the rats' next sleep cycle. Significantly higher overall frontal and parietal cortical power was seen in a wide range of EEG frequencies in adolescent rats as compared to adult rats in their waking EEG. Acute administration of ethanol did not produce differences between adolescents and adults on behavioral measures of acute intoxication. However, it did produce a significantly less intense acute EEG response to ethanol in the theta frequencies in parietal cortex in the adolescents as compared to the adults. At 20 h following acute ethanol administration, during the rats' next sleep cycle, a decrease in slow-wave frequencies (1-4 Hz) was seen and the adolescent rats were found to display more reduction in the slow-wave frequencies than the adults did. The present study found that adolescent rats, as compared to adults, demonstrate low sensitivity to acute ethanol administration in the theta frequencies and more susceptibility to disruption of slow-wave sleep during hangover. These studies may lend support to the idea that these traits may contribute to increased risk for alcohol use disorders seen in adults who begin drinking in their early teenage years.

    In patients undergoing surgical myocardial revascularization for acute myocardial infarction, excellent myocardial protection can be achieved by blood cardioplegia. We investigated the influence of age on cardiac function, metabolism, and infarct size using Buckberg's blood cardioplegia (BCP). The hearts of male Wistar rats ("adult", age 3 months, n = 8; "senile", age 24 months, n = 8) were excised and mounted on a blood-perfused isolated heart apparatus. An acute myocardial infarction was induced by coronary artery ligation for 30 min before aortic clamping and infusion of Buckberg's BCP. Throughout the experiment, functional parameters were recorded: coronary blood flow (normalized by heart weight), left ventricular peak developed pressure (LVpdP), and positive and negative derived left ventricular pressure over time (dLVPdt max and dLVPdt min ). Oxygen consumption (MVO 2 ) and lactate production of the hearts were calculated. The infarct size after 90 min of reperfusion (in % of the area at risk) was measured with triphenyl tetrazolium chloride staining of the myocardium. The baseline coronary flow normalized by heart weight was significantly lower in the senile hearts (1.6 ± 0.4 ml/(min ∗ g)) compared with the adult hearts (2.0 ± 0.3 ml/(min ∗ g); p = 0.04). After 90 min of aortic clamping, hemodynamic function of senile hearts recovered better than that of adult hearts: LVpdP (adult 57% of baseline [BL]; senile 88% BL; p = 0.044) and dLVPdt max (adult 74% BL, senile 102% BL; p = 0.12). In contrast, myocardial infarct size was similar between the adult (26%) and senile (21%; p = 0.45) hearts, and coronary flow recovered to a similar extent (55% BL and 58% BL, respectively). During reperfusion, MVO 2 (80% BL and 81% BL) and lactate production (1.2 and 1.3 μmol/min) were similar in the two groups. After acute myocardial infarction in a rat model, hearts recovered function after reperfusion with

    To present the findings of a structured literature review that aimed to identify the influences on the health, safety and welfare of adults with learning disabilities in acute hospitals. There is increasing evidence regarding the inadequacy of care for people with learning disabilities in acute care settings. However, few studies have specifically addressed their health, safety and welfare in such contexts. Four key electronic databases (Medline; PsycINFO; British Nursing Index and archive; Cumulative Index to Nursing and Allied Health Literature) were searched for relevant literature published between 2000 and 2011. Publications assessed as meeting the inclusion criteria were retrieved in full. Data were extracted regarding methods used; primary aims of the study being reported; and key findings. Of the 3505 papers identified in the initial search, eight met the inclusion criteria. Analysis revealed six areas of influence on the health, safety and welfare of adults with learning disabilities in acute hospitals: care provision (meeting health and personal needs); communication; staff attitudes; staff knowledge; supporters; and carers (valuing their role); physical environment. We represent these six areas diagrammatically, as concentric rings. These influence on health, safety and welfare form an inner (direct) layer and an outer (indirect) layer consisting of liaison services and education/training. This new conceptualisation of influences as being multi-layered assists in the identification of similarly multi-layered improvement strategies. Adults with learning disabilities can exert their own influence on health, safety and welfare and should be supported to make decisions about their own care. More broadly they should be involved with policy development, nurse education and research. This can be achieved through inclusive approaches, for example, inviting people with learning disabilities to input into nursing curricula or to engage in research as

    Abstract Dietary nitrate ( NO 3 − ) is converted to nitrite ( NO 2 − ) and can be further reduced to the vasodilator nitric oxide (NO) amid a low O2 environment. Accordingly, dietary NO 3 − increases hind limb blood flow in rats during treadmill exercise; however, the evidence of such an effect in humans is unclear. We tested the hypothesis that acute dietary NO 3 − (via beetroot [BR] juice) increases forearm blood flow (FBF) via local vasodilation during handgrip exercise in young adults (n ...

    The aim of this chart review of adult patients treated for acute lymphoblastic leukemia (ALL) with total body irradiation (TBI) was to evaluate early and late toxicity and long-term outcome. A total of 110 adult patients (34 ± 12 years) with ALL underwent TBI (6 fractions of 2 Gy for a total of 12 Gy) as a part of the treatment regimen before transplantation. Treatment-related toxicity, mortality, and hematologic outcome are reported. Mean follow-up was 70 months. The 2- and 5-year leukemia-free survival rates were 78 and 72 %, respectively. In all, 29 % (32/110) patients suffered from medullary recurrence after a median time of 7 months. Gender was the only statistically significant prognostic factor in terms of overall survival in favor of female patients. Treatment-related mortality and overall survival after 2 and 5 years were 16 and 22 %, and 60 and 52.7 %, respectively. The most frequent late reaction wascGVHD of the skin (n = 33, 30 %). In addition, 15.5 % (17/110 patients) suffered pulmonary symptoms, and 6 patients developed lung fibrosis. Eyes were frequently affected by the radiation (31/110 = 28 %); 12 of 110 patients (11 %) presented with symptoms from osteoporosis, 5 of 110 patients (4.5 %) developed hypothyreosis and 2 patients diabetes mellitus. Of the male patients, 11 % reported erectile dysfunction or loss of libido, while 2 of 36 women reported menopausal syndrome at the mean time of 28 months after treatment with requirement for substitution. No women became pregnant after treatment. No acute or late cardiac toxicities were documented in our patients. No secondary malignancies were documented. Although hematologic outcome was in the upper range of that reported in the literature, treatment-related mortality (TRM) and medullary recurrences remain a challenge. Sophisticated radiation techniques allow for decreasing toxicity to certain organs and/or dose escalation to the bone marrow in highly selected patients in order to improve therapeutic

    Aims Despite the benefits of regular physical activity participation following acute myocardial infarction, little is known about gender differences in physical activity among patients after acute myocardial infarction. We described, by gender, physical activity trajectories pre- and post-acute myocardial infarction, and determined whether gender was independently associated with physical activity. Methods and results The Variation in Recovery: Role of Gender on Outcomes of Young AMI patients (VIRGO) study, conducted at 103 US, 24 Spanish, and three Australian hospitals, was designed, in part, to evaluate gender differences in lifestyle behaviors following acute myocardial infarction. We used baseline, one-month, and 12-month data collected from patients aged 18-55 years ( n = 3572). Patients were assigned to American Heart Association-defined levels of physical activity. A generalized estimating equation model was used to account for repeated measures within the same individual over time. Men were more active (≥150 min/wk moderate or ≥75 min/wk vigorous activity) than women at baseline (42% vs 34%), one month (45% vs 34%), and 12 months (48% vs 36%) (all p acute myocardial infarction to 12-months post-acute myocardial infarction (95% confidence interval: 1.21-1.55). Non-white race, non-active workplaces, smoking, diabetes, hypertension, and obesity were also associated independently with being less active over time (all p acute myocardial infarction were less likely to meet physical activity recommendations than were men. By identifying factors associated with low levels of activity during acute myocardial infarction recovery, targeted interventions can be introduced prior to hospital discharge.

    The purpose of this study was to summary the clinical and laboratorial features in 15 adult cases of mixed phenotypic acute leukemia with Ph chromosome and/or BCR-ABL fusion gene positive (Ph(+)MPAL), 15 adult patients with Ph(+)MPAL were defined by WHO-2008 classification. The clinical characteristics, results of morphology, immunology, cytogenetics and molecular genetic detections and results of follow-up in 15 adult patients with Ph(+)MPAL were analyzed retrospectively. The results showed that 15 patients among 87 cases of MPAL demonstrated Ph(+)MPAL (17.2%; 15/87) (7 males and 8 females), their median age was 51 (range 16-81) year old and median WBC count at diagnosis was 69 (12.7-921)×10(9)/L. Based on FAB criteria, these patients showed different morphologic types, including AML (13.3%; 2/15), ALL (40.0%; 6/15), HAL (46.7%; 7/15). Immunologic analysis indicated that 15 cases of Ph(-)MPAL were all classified as B-lymphoid +myeloid mixed immunophenotype. Except one patient, all expressed CD34 antigen on the surface of leukemia cells with 64.3% strong positive, only Ph (53.3%; 8/15), Ph with additional chromosomal abnormalities (33.3%; 5/15) and normal karyotype (13.3%; 2/15) were cytogenetically identified. BCR-ABL fusion gene transcript positive were detected by multiplex reverse transcription PCR in all cases, with e1a2 subtype (p190) (40.0%; 6/15) and b2a2 or b3a2 (p210) subtype (60.0%; 9/15). Four out of 7 (57.1%) patients were found to have IKZF1 gene deletion, without other common gene mutations. Seven out of 10 cases (70.0%) achieved complete remission (CR) after one cycle of induction chemotherapy. In the induction stage, CR rate seemed higher when tyrosine kinase inhibitors (TKI) were added to chemotherapy (83.3%:50.0%; P = 0.206). Overall survival (OS) in 4 patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) was longer than that in 4 patients received chemotherapy alone (P = 0.004). It is concluded that Ph(+)MPAL mainly

    Systemic complications related to acute pancreatitis include acute respiratory distress syndrome, multiple organ dysfunction syndrome, disseminated intravascular coagulation, hypocalcemia, hyperglycemia, and insulin dependent diabetes or diabetic ketoacidosis. In practice, the development of diabetic ketoacidosis induced by acute pancreatitis is rare and generally associated with hypertriglyceridemia. However, herein we report a case of a 34-year-old female without hypertriglyceridemia, who was diagnosed with acute pancreatitis complicated with diabetic ketoacidosis. The patient was admitted with complaints of febrile sensation, back pain, and abdominal pain around the epigastric area. Levels of serum amylase and lipase were elevated to 663 U/L and 3,232 U/L. Contrast-enhanced abdominal CT showed pancreatic swelling, peri-pancreatic fat infiltration and fluid collection. The patient was initially diagnosed with simple acute pancreatitis. Though the symptoms were rapidly relieved after initiation of treatment, severe hyperglycemia (575 mg/dL), severe metabolic acidosis (pH 6.9), and ketonuria developed at four days after hospitalization. However, serum triglyceride levels remained within the normal range (134 mg/dL). Finally, the patient was diagnosed with acute pancreatitis complicated with diabetic ketoacidosis unrelated to hypertriglyceridemia. She recovered through insulin and fluid therapy, and receives insulin therapy at the outpatient clinic.

    Congenital abnormalities of the penis are usually diagnosed at birth and pose aesthetic and functional problems sometimes requiring surgical management. A literature review was conducted on Medline considering the articles listed until January 2012. Hypospadias is the most common malformation (1 in 250 boys. Familial forms: 7%). The causes remain hypothetical but the doubling of the incidence in 30 years could be linked to fetal exposure to endocrine disruptors "estrogen-like" used in the food industry in particular. Surgical treatment is usually intended to improve the aesthetic appearance but sometimes, in case of significant curvature or posterior meatus, necessary for normal sexual life and fertility. Other malformations (epispades, buried penis, transpositions, twists and preputial abnormalities) as well as management for functional or aesthetic consequences of these malformations in adulthood require complex surgical care in a specialized environment. The improvement of surgical techniques and pediatric anesthesia allows an early and effective specialized surgical approach of penile malformations. Management of sequelae in adulthood must be discussed and requires experience of surgical techniques on pediatric and adult penis. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Rape trauma contributes significantly to the mental burden of disease, affecting resilience and vulnerabilities at every developmental life stage. Appropriate resilience-promoting strategies could potentially buffer or protect trauma-exposed individuals from psychopathology. This study aimed to assess and compare (using validated measuring instruments) resilience, post-traumatic stress disorder (PTSD) and other variables in the acute aftermath of rape, between adolescent and adult females and to assess associations with these variables. We conducted a comparative analysis of resilience, PTSD, prior trauma, demographic variables and psychiatric morbidity in 41 adolescent and 47 adult female rape survivors six weeks post-rape. We assessed the relationship of resilience to PTSD, demographic variables and prior trauma and investigated if resilience levels predicted PTSD after adjusting for prior trauma. We found no significant differences in resilience levels between the groups, but the adolescent PTSD rate (40%) was double that in adults (20%). In adults, a significant negative correlation was evident between resilience and PTSD symptoms scores. More knowledge of resilience versus stress susceptibility for PTSD throughout the lifespan is needed and can inform the development of more effective clinical assessment and resilience-promoting strategies.

    Norovirus (NoV) infections that cause acute gastroenteritis are commonly observed during colder months. This study was conducted to investigate the clinical features and molecular epidemiology of NoVs in adult outpatients with acute gastroenteritis in Beijing, China from August 2008 to July 2009. Five hundred nineteen patients were enrolled, their stool specimens were collected, and 136 (26.2%) were positive for NoV. The elderly were found to be more susceptible to NoVs than other age groups. The greatest number of gastroenteritis cases associated with occurred in October. Six GI and eleven GII NoV genotypes were isolated; among these, the GII.4 genotype was most prevalent (70/140 and 50% were the 2006b variant). The elderly were more susceptible to the GII.4 genotype than to other genotypes. Greater numbers of neutrophils in the peripheral blood were observed in the NoV infected group than in uninfected control group. However, the levels of neutrophils and leukocytes in the non-GII.4 patients infected with NoV were higher than those of the GII.4-infected patients. The data highlight the role of NoV as a primary agent responsible for gastroenteritis in adults in Beijing, China. © 2014 Wiley Periodicals, Inc.

    To investigate the characteristics and the short- or long-term treatment outcomes of the adult patients with acute myeloid leukemia (AML) in China. From 1999 to 2010, 822 adult cases with AML were enrolled, diagnosed and classified by the FAB and WHO criteria, respectively. The treatment outcomes and prognostic factors were analyzed retrospectively. In all patients with a median age of 38.5(15-83) years, acute monoblastic and monocytic leukemia (M5), AML with t(15;17)/PML-RARα (APL) and AML with t(8;21)/AML1-ETO(M2b) were the most common subtypes, accounting for 29.7%, 20.9% and 14.6% respectively. In APL patients, CR was achieved in 95.2%, with an early death (ED) rate of 4.8%. And the estimated overall survival (OS) and disease-free survival (DFS) at 5 year was 87.5% and 88.8%, respectively. Patients with other AML subtype (Non-APL) revealed a CR rate of 82.0%, ED of 4.3%, and estimated 5-year OS and DFS both of 48.8%. The OS rate of Non-APL patients at 3-year varied significantly (Pleukemia centers. Chemotherapy by risk stratification, after diagnosis and classification according to the WHO criteria, is a key point to improve the outcomes in AML.

    To evaluate the effect of tobacco smoking on the risk of non-fatal acute myocardial infarction in young adults (infarction cases (42 women; 287 men), consecutively admitted to the Cardiology department of hospitals in Porto, Portugal, and 778 controls (486 women; 292 men), selected within the non-institutionalized Porto population, during 2001-2003. Odds ratios and 95% confidence intervals (OR, 95%CI) were calculated using unconditional logistic regression. The prevalence of current smoking was 80.8% in male cases and 53.8% in male controls (OR=3.63, 95%CI: 2.50, 5.27) and 59.5% of female cases were smokers compared to 35.8% of controls (OR=2.64, 95%CI: 1.39, 5.02). No interaction was found between current smoking and sex on myocardial infarction risk (p=0.401). A dose-effect response was present, the odds favoring myocardial infarction reaching an eight-fold increase for those that smoked > 25 cigarettes/day compared to never smokers. The risk estimate for former smokers was similar to never smokers. Tobacco smoking is an important independent risk factor for acute myocardial infarction in young adults, with similar strength of association for both sexes.

    To investigate and compare the clinical implications of p16 deletion in childhood and adult B-lineage acute lymphoblastic leukemia (B-ALL). A total of 129 cases of de novo childhood (73 cases) and adult (56 cases) B-ALL were examined genetically and immunologically using G-banding techniqhe, interphase fluorescence in situ hybridization (I-FISH) and immunophenotyping by flow cytometry, and their clinical data were retrospectively analyzed. Of 73 childhood cases, the prevalences of homozygous deletion, hemizygous deletion and no deletion of p16 were 24.7% (18 cases), 6.8% (5 cases) and 68.5% (50 cases) respectively, and of 56 adult cases, the incidences as of 14.3% (8 cases), 8.9% (5 cases) and 76.8% (43 cases) respectively. The incidence of p16 deletion between the two groups had no significant difference (P = 0.338). In both groups, patients with or without p16 deletion had no significant difference in terms of white blood cells (WBC) count at diagnosis, BM blast percentage, chromosome karyotype, extra-infiltration and CR1 rate. Of note, there were 2 cases, each in childhood and adult, showed no deletion at the time of diagnosis, their p16 deletions occurred at relapse. The deletion of p16 was associated with poor overall survival and event-free survival (EFS) in both childhood and adults. According to the standard of NCI risk stratification, we divided patients of two groups into standard and high risk category respectively, and performed further analysis. The significance of different risk category in children and adults was disparity. The overall survival (OS) rates of deletion and no deletion of p16 were 45.3% and 79.8% (P = 0.006) in children, and 7.7% and 22.6% (P = 0.002) in adults, respectively. EFS rates of deletion and no deletion of p16 were 33.5% and 58.1% (P = 0.008) in children, and 0 and 10.9% (P study indicated that deletion of p16 was associated with poor prognosis in both childhood and adult B-ALL, which highlighted an important significance to

    Background The acute effects of grape polyphenols on endothelial function in adults are inconsistent. Here, we performed meta-analyses to determine these acute effects as measured by flow-mediated dilation (FMD). Methods Trials were searched in PubMed, Embase and the Cochrane Library database. Summary estimates of weighted mean differences (WMDs) and 95% CIs were obtained by using random-effects models. Meta-regression and subgroup analyses were performed to identify the source of heterogeneity. The protocol details of our meta-analysis have been submitted to the PROSPERO register and our registration number is CRD42013004157. Results Nine studies were included in the present meta-analyses. The results showed that the FMD level was significantly increased in the initial 120 min after intake of grape polyphenols as compared with controls. Meta-regression and subgroup analyses were performed and showed that a health status was the main effect modifier of the significant heterogeneity. Subgroups indicated that intake of grape polyphenols could significantly increase FMD in healthy subjects, and the increased FMD appeared to be more obviously in subjects with high cardiovascular risk factors. Moreover, the peak effect of grape polyphenols on FMD in healthy subjects was found 30 min after ingestion, which was different from the effect in subjects with high cardiovascular risk factors, in whom the peak effect was found 60 min after ingestion. Conclusions Endothelial function can be significantly improved in healthy adults in the initial 2 h after intake of grape polyphenols. The acute effect of grape polyphenols on endothelial function may be more significant but the peak effect is delayed in subjects with a smoking history or coronary heart disease as compared with the healthy subjects.

The acute effect of grape polyphenols on endothelial function may be more significant but the peak effect is delayed in subjects with a smoking history or coronary heart disease as compared with the healthy subjects.

    The acute effects of grape polyphenols on endothelial function in adults are inconsistent. Here, we performed meta-analyses to determine these acute effects as measured by flow-mediated dilation (FMD). Trials were searched in PubMed, Embase and the Cochrane Library database. Summary estimates of weighted mean differences (WMDs) and 95% CIs were obtained by using random-effects models. Meta-regression and subgroup analyses were performed to identify the source of heterogeneity. The protocol details of our meta-analysis have been submitted to the PROSPERO register and our registration number is CRD42013004157. Nine studies were included in the present meta-analyses. The results showed that the FMD level was significantly increased in the initial 120 min after intake of grape polyphenols as compared with controls. Meta-regression and subgroup analyses were performed and showed that a health status was the main effect modifier of the significant heterogeneity. Subgroups indicated that intake of grape polyphenols could significantly increase FMD in healthy subjects, and the increased FMD appeared to be more obviously in subjects with high cardiovascular risk factors. Moreover, the peak effect of grape polyphenols on FMD in healthy subjects was found 30 min after ingestion, which was different from the effect in subjects with high cardiovascular risk factors, in whom the peak effect was found 60 min after ingestion. Endothelial function can be significantly improved in healthy adults in the initial 2 h after intake of grape polyphenols. The acute effect of grape polyphenols on endothelial function may be more significant but the peak effect is delayed in subjects with a smoking history or coronary heart disease as compared with the healthy subjects.

    Habitual stretching exercise increases carotid arterial compliance, and acute stretching exercise increases arterial compliance in patients with myocardial infarction. However, it is not known whether this arterial adaptation is sustained after exercise. The aim of this study was to examine the effect of a single bout of stretching exercise on the time course of systemic, central, and peripheral arterial stiffness in healthy young subjects. Twenty-six healthy young men performed static stretching exercise involving the entire body (trunk, upper limb, and lower limb) for 40 mins. Pulse-wave velocity (PWV; an index of arterial stiffness), blood pressure, and heart rate were measured before and 0, 15, 30, and 60 mins after stretching exercise. Femoral-ankle PWV and brachial-ankle PWV were reduced relative to baseline 15 and 30 mins after acute stretching (P stretch stimulation may result in chronic high arterial compliance, although a single bout of stretch exercise acutely affects arterial compliance.

    Full Text Available Posttraumatic stress disorder is a long-lasting psychiatric disease with the consequence of hippocampal atrophy in humans exposed to severe fatal stress. We demonstrated a positive correlation between the transient decline of 5-bromo-2′-deoxyuridine (BrdU incorporation in the hippocampal dentate gyrus (DG and long-lasting behavioral abnormalities in mice with traumatic stress. Here, we investigated pharmacological properties of theanine on the declined BrdU incorporation and abnormal behaviors in mice with traumatic stress. Prior daily oral administration of theanine at 50–500 mg/kg for 5 days significantly prevented the decline of BrdU incorporation, while theanine significantly prevented the decline in the DG even when administered for 5 days after stress. Consecutive daily administration of theanine significantly inhibited the prolonged immobility in mice with stress in forced swimming test seen 14 days later. Although traumatic stress significantly increased spontaneous locomotor activity over 30 min even when determined 14 days later, the increased total locomotion was significantly ameliorated following the administration of theanine at 50 mg/kg for 14 days after stress. These results suggest that theanine alleviates behavioral abnormalities together with prevention of the transient decline of BrdU incorporation in the hippocampal DG in adult mice with severe traumatic stress.

    Rapid antigen detection tests (RADT) are commonly used to guide appropriate antibiotic treatment of group A beta-hemolytic streptococcal (GABHS) pharyngitis. In adults, there is controversy about the need for routine backup testing of negative RADT. Estimate the costs and benefits in adults of routine backup testing by DNA Gen-probe of negative RADT (Acceava). Observational follow-up study. All patients aged 18 years and older visiting a Cleveland Clinic generalist physician in 2009 and 2010 with a visit diagnosis of acute pharyngitis (ICD codes 462, 034.0). The patients were identified using the Cleveland Clinic Epic Clarity database. We determined the proportion of false negative RADT, antibiotic prescription patterns and rate of serious suppurative complications within 30 days of the office visit. Of 25,130 patients with acute pharyngitis, 19% had no testing and 81% were tested. Of the 15,555 patients that had a negative RADT and follow-up DNA probe, 6% had a positive DNA probe. Of the 953 patients who had a negative RADT and a positive DNA strep probe, 48% received an antibiotic prescription at the time of the visit and 51% received an antibiotic prescription after an average of 2.3 days. Only one patient with a negative RADT and no follow-up DNA probe developed a peritonsillar abscess. Overall, of the 15,555 DNA probes performed, management was altered in only 3% of the patients at a total cost of $1,757,715. Fifty-six percent received an antibiotic while only 19.5% had a confirmed strep throat diagnosis. The false negative rate of Acceava RADT for the diagnosis of GABHS pharyngitis was 6%. We question the benefit of routine DNA probe backup testing in adults because of its substantial cost, an average delay in antibiotic prescribing of over 2 days, and because suppurative complications are very uncommon. We found a high rate of inappropriate antibiotic prescribing.

    Adult neurogenesis, the generation of new neurons in the adult brain, occurs in the hippocampal dentate gyrus (DG) and the olfactory bulb (OB) of all mammals, but the functions of these new neurons are not entirely clear. Originally, adult-born neurons were considered to have excitatory effects on the DG network, but recent studies suggest a net inhibitory effect. Therefore, we hypothesized that selective removal of newborn neurons would lead to increased susceptibility to the effects of a convulsant. This hypothesis was tested by evaluating the response to the chemoconvulsant kainic acid (KA) in mice with reduced adult neurogenesis, produced either by focal X-irradiation of the DG, or by pharmacogenetic deletion of dividing radial glial precursors. In the first 4 hrs after KA administration, when mice have the most robust seizures, mice with reduced adult neurogenesis had more severe convulsive seizures, exhibited either as a decreased latency to the first convulsive seizure, greater number of convulsive seizures, or longer convulsive seizures. Nonconvulsive seizures did not appear to change or they decreased. Four-21 hrs after KA injection, mice with reduced adult neurogenesis showed more interictal spikes (IIS) and delayed seizures than controls. Effects were greater when the anticonvulsant ethosuximide was injected 30 min prior to KA administration; ethosuximide allows forebrain seizure activity to be more easily examined in mice by suppressing seizures dominated by the brainstem. These data support the hypothesis that reduction of adult-born neurons increases the susceptibility of the brain to effects of KA. PMID:25476494

    Race-based survival in children and adolescents with hematologic malignancies has been a national challenge for decades. Large-scale investigations of age- and race-based survival trends over time in these patients have not previously been reported. The objective of this study was to investigate whether race- and age-related differences in pediatric and adolescent and young adult (AYA) leukemia and lymphoma survival persist and to what extent these differences have changed over time. Using the Surveillance, Epidemiology, and End Results program, this study investigated the outcomes of black and white (1975-2012; n = 27,369) and white and Hispanic (1992-2012; n = 20,574) children (0-14 years old) and AYAs (15-39 years old) with acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), and Hodgkin lymphoma (HL). Estimates of 5- and 10-year relative survival were compared over time. Trends showed a convergence of survival for white and black children with ALL but a divergence in survival for AYA patients. Hispanic children and AYAs both suffered inferior outcomes. Trends for AML revealed persistent survival differences between black and white children and suggested worsening disparities for AYAs. Survival trends in HL revealed sustained survival differences between black and white AYA patients, whereas no differences were found in Hispanic and white patient outcomes for AML or HL. Although survival for children and AYAs with ALL, AML, and HL has improved over the past 4 decades, differences persist between black, white, and Hispanic children and AYAs; survival disparities between black and white children with ALL have been nearly eliminated. Strategies aimed at identifying causality and reducing disparities are warranted. Cancer 2016. © 2016 American Cancer Society.
