    To determine the clinical utility of FISH for del(5q) in MDS/AML, we first compared FISH for 5q31 (EGR1) and 5q33 (CSF1R) in 51 myeloid neoplasms containing del(5q) by metaphase cytogenetics. Next, EGR1 FISH was compared to metaphase cytogenetics alone in 269 cases of known or suspected MDS/AML. These studies show that while metaphase cytogenetics alone can detect del(5q) in most cases, FISH is particularly useful in cases with suboptimal growth. EGR1 FISH detects del(5q) in a broad variety of myeloid neoplasms, including at least most cases of 5q- syndrome, while studies for CSF1R add little to the diagnostic yield.

    Full Text Available Abstract Background While lenalidomide (LEN shows high efficacy in myelodysplastic syndromes (MDS with del[5q], responses can be also seen in patients presenting without del[5q]. We hypothesized that improved detection of chromosomal abnormalities with new karyotyping tools may better predict response to LEN. Design and methods We have studied clinical, molecular and cytogenetic features of 42 patients with MDS, myeloproliferative neoplasms (MPN, MDS/MPN overlap syndromes and secondary acute myeloid leukemia (sAML without del[5q] by metaphase cytogenetics (MC who underwent therapy with LEN. Results Fluorescence in situ hybridization (FISH or single nucleotide polymorphism array (SNP-A-based karyotyping marginally increased the diagnostic yield over MC, detecting 2/42 (4.8% additional cases with del[5q], one of whom were responded to LEN. Responses were more often observed in patients with a normal karyotype by MC (60% vs abnormal MC; 17%, p = .08 and those with gain of chromosome 8 material by either of all 3 karyotyping methods (83% vs all other chromosomal abnormalities; 44% p = .11. However, 5 out of those 6 patients received combined LEN/AZA therapy and it may also suggest those with gain of chromosome 8 material respond well to AZA. The addition of FISH or SNP-A did not improve the predictive value of normal cytogenetics by MC. Mutational analysis of TET2, UTX, CBL, EZH2, ASXL1, TP53, RAS, IDH1/2, and DNMT-3A was performed on 21 of 41 patients, and revealed 13 mutations in 11 patients, but did not show any molecular markers of responsiveness to LEN. Conclusions Normal karyotype and gain of chromosome 8 material was predictive of response to LEN in non-del[5q] patients with myeloid malignancies.

    Del(5q) myelodysplastic syndromes defined by the International Prognostic Scoring System as low- or intermediate-1-risk (lower-risk) are considered to have an indolent course; however, recent data have identified a subgroup of these patients with more aggressive disease and poorer outcomes. Using deep sequencing technology, we previously demonstrated that 18% of patients with lower-risk del(5q) myelodysplastic syndromes carry TP53 mutated subclones rendering them at higher risk of progression. In this study, bone marrow biopsies from 85 patients treated with lenalidomide in the MDS-004 clinical trial were retrospectively assessed for p53 expression by immunohistochemistry in association with outcome. Strong p53 expression in ≥1% of bone marrow progenitor cells, observed in 35% (30 of 85) of patients, was significantly associated with higher acute myeloid leukemia risk (P=0.0006), shorter overall survival (P=0.0175), and a lower cytogenetic response rate (P=0.009), but not with achievement or duration of 26-week transfusion independence response. In a multivariate analysis, p53-positive immunohistochemistry was the strongest independent predictor of transformation to acute myeloid leukemia (P=0.0035). Pyrosequencing analysis of laser-microdissected cells with strong p53 expression confirmed the TP53 mutation, whereas cells with moderate expression predominantly had wild-type p53. This study validates p53 immunohistochemistry as a strong and clinically useful predictive tool in patients with lower-risk del(5q) myelodysplastic syndromes. This study was based on data from the MDS 004 trial (clinicaltrials.gov identifier: NCT00179621). PMID:24682512

    A patient with refractory primary immune thrombocytopenia (ITP) characterised by severe skin and mucosal bleedings was treated with several ITP-directed therapies including cyclophosphamide. He later developed therapy-related del(5q) myelodysplastic syndrome with no dysplastic morphological features in bone marrow. He remained severely thrombocytopenic, which suggests ongoing immune mediated platelet destruction. After two 3 week cycles of low-dose lenalidomide, complete cytogenetic remission and complete normalisation of platelet count were observed. This suggests that lenalidomide may be a viable treatment option for ITP in the presence of del(5q) not responding to standard treatments.

    Lenalidomide is a highly effective treatment for myelodysplastic syndrome (MDS) with deletion of chromosome 5q (del(5q)). Here, we demonstrate that lenalidomide induces the ubiquitination of casein kinase 1A1 (CK1α) by the E3 ubiquitin ligase CUL4-RBX1-DDB1-CRBN (known as CRL4(CRBN)), resulting in CK1α degradation. CK1α is encoded by a gene within the common deleted region for del(5q) MDS and haploinsufficient expression sensitizes cells to lenalidomide therapy, providing a mechanistic basis for the therapeutic window of lenalidomide in del(5q) MDS. We found that mouse cells are resistant to lenalidomide but that changing a single amino acid in mouse Crbn to the corresponding human residue enables lenalidomide-dependent degradation of CK1α. We further demonstrate that minor side chain modifications in thalidomide and a novel analogue, CC-122, can modulate the spectrum of substrates targeted by CRL4(CRBN). These findings have implications for the clinical activity of lenalidomide and related compounds, and demonstrate the therapeutic potential of novel modulators of E3 ubiquitin ligases.

    Lenalidomide induces in patients with myelodysplastic syndrome (MDS) and del(5q) erythroid and cytogenetic response rates as high as 75% and 50%, respectively. It is still unclear, however, how long lenalidomide treatment should be continued and whether or not the drug could be interrupted. To assess the feasibility of lenalidomide discontinuation, we revised a cohort of 16 low-risk MDS patients with del(5q) treated at our institute in a phase II multicentric Italian study. Among the 12 responding patients, four discontinued lenalidomide while in complete response. All four patients needed during treatment a permanent lenalidomide reduction from 10 to 5 mg/day because of haematological toxicity (three patients) or grade 3 muscular and bone pain (one patient). At lenalidomide discontinuation after 16, 20, 27 and 20 months from the start, respectively, all four patients were in complete hematologic response and three forth in complete cytogenetic response. Three patients are still in response after 36, 30 and 20 months from lenalidomide discontinuation, respectively: The remaining patient relapsed after 20 months, and she is now receiving a new course of lenalidomide. In conclusion, long-lasting remissions are achievable in MDS patients with del(5q) in complete response after lenalidomide discontinuation.

    Interstitial deletion of chromosome 5q is the most common chromosomal abnormality in myelodysplastic syndromes. The catalogue of genes involved in the molecular pathogenesis of myelodysplastic syndromes is rapidly expanding and next-generation sequencing technology allows detection of these mutations at great depth. Here we describe the design, validation and application of a targeted next-generation sequencing approach to simultaneously screen 25 genes mutated in myeloid malignancies. We used this method alongside single nucleotide polymorphism-array technology to characterize the mutational and cytogenetic profile of 43 cases of early or advanced del(5q) myelodysplastic syndromes. A total of 29 mutations were detected in our cohort. Overall, 45% of early and 66.7% of advanced cases had at least one mutation. Genes with the highest mutation frequency among advanced cases were TP53 and ASXL1 (25% of patients each). These showed a lower mutation frequency in cases of 5q- syndrome (4.5% and 13.6%, respectively), suggesting a role in disease progression in del(5q) myelodysplastic syndromes. Fifty-two percent of mutations identified were in genes involved in epigenetic regulation (ASXL1, TET2, DNMT3A and JAK2). Six mutations had allele frequencies <20%, likely below the detection limit of traditional sequencing methods. Genomic array data showed that cases of advanced del(5q) myelodysplastic syndrome had a complex background of cytogenetic aberrations, often encompassing genes involved in myeloid disorders. Our study is the first to investigate the molecular pathogenesis of early and advanced del(5q) myelodysplastic syndromes using next-generation sequencing technology on a large panel of genes frequently mutated in myeloid malignancies, further illuminating the molecular landscape of del(5q) myelodysplastic syndromes.

    Lenalidomide is approved for the treatment of transfusion-dependent (TD) del(5q) myelodysplastic syndromes (MDS). However, few data are available in patients with transfusion-independent (TI) del(5q) MDS. In the first, observational, part of this 2-part study, we assessed the impact of transfusion dependence on overall survival (OS) and non-leukemic death in untreated del(5q) MDS patients who were TD (n = 136), TI with hemoglobin (Hb) ≥10 mg/dL (n = 88), or TI with Hb lenalidomide (10 mg/day) in 12 patients with TI del(5q) MDS and Hb lenalidomide (+12.5; P = 0.020). Evaluable TI patients experienced early increases in Hb levels, and all attained an erythroid response. Our findings suggest that TI patients with moderate anemia may benefit from early treatment with lenalidomide.

    Deletion of the long arm of chromosome 5, del(5q), is the most prevalent cytogenetic abnormality in patients with myelodysplastic syndromes (MDS). In isolation, it is traditionally associated with favorable prognosis compared with other subtypes of MDS. However, owing to the inherent heterogeneity of the disease, prognosis for patients with del(5q) MDS is highly variable depending on the presence of factors such as additional chromosomal abnormalities, >5 % blasts in the bone marrow (BM), or transfusion dependence. Over recent years, the immunomodulatory drug lenalidomide has demonstrated remarkable efficacy in patients with del(5q) MDS. Advances in the understanding of the pathogenesis of the disease have suggested that lenalidomide targets aberrant signaling pathways caused by haplosufficiency of specific genes in a commonly deleted region on chromosome 5 (e.g., SPARC, RPS14, Cdc25C, and PP2A). As a result, the agent specifically targets del(5q) clones while also promoting erythropoiesis and repopulation of the bone marrow in normal cells. This review discusses recent developments in the understanding of the mechanism of action of lenalidomide, and how this underlies favorable outcomes in patients with del(5q) MDS. In addition, we discuss how improved understanding of the mechanism of disease will facilitate clinicians' ability to predict/monitor response and identify patients at risk of relapse.

    Diamond Blackfan anemia (DBA) and myelodysplastic syndrome (MDS) with isolated del(5q) are severe macrocytic anemias; although both are associated with impaired ribosome assembly, why the anemia occurs is not known. We cultured marrow cells from DBA (n = 3) and del(5q) MDS (n = 6) patients and determined how heme (a toxic chemical) and globin (a protein) are coordinated. We show that globin translation initiates slowly, whereas heme synthesis proceeds normally. This results in insufficient globin protein, excess heme and excess reactive oxygen species in early erythroid precursors, and CFU-E (colony-forming unit-erythroid)/proerythroblast cell death. The cells that can more rapidly and effectively export heme or can slow heme synthesis preferentially survive and appropriately mature. Consistent with these observations, treatment with 10 μM succinylacetone, a specific inhibitor of heme synthesis, improved the erythroid cell output of DBA and del(5q) MDS marrow cultures by 68 to 95% (P = 0.03 to 0.05), whereas the erythroid cell output of concurrent control marrow cultures decreased by 4 to 13%. Our studies demonstrate that erythropoiesis fails when heme exceeds globin. Our data further suggest that therapies that decrease heme synthesis (or facilitate heme export) could improve the red blood cell production of persons with DBA, del(5q) MDS, and perhaps other macrocytic anemias.

    Acute lymphoblastic leukemia (ALL), a clonal expansion of hematopoietic blasts, is a highly heterogeneous disease comprising many entities for which distinct treatment strategies are pursued. Although ALL is a success story in pediatric oncology, results in adults lag behind those in children. An expansion of new drugs, more reliable immunologic and molecular techniques for the assessment of minimal residual disease, and efforts at more precise risk stratification are generating new aspects of adult ALL therapy. For this review, the authors summarized pertinent and recent literature on ALL biology and therapy, and they discuss current strategies and potential implications of novel approaches to the management of adult ALL.

    This international phase III, randomized, placebo-controlled, double-blind study assessed the efficacy and safety of lenalidomide in RBC transfusion-dependent patients with International Prognostic Scoring System lower-risk non-del(5q) myelodysplastic syndromes ineligible for or refractory to erythropoiesis-stimulating agents. In total, 239 patients were randomly assigned (2:1) to treatment with lenalidomide (n = 160) or placebo (n = 79) once per day (on 28-day cycles). The primary end point was the rate of RBC transfusion independence (TI) ≥ 8 weeks. Secondary end points were RBC-TI ≥ 24 weeks, duration of RBC-TI, erythroid response, health-related quality of life (HRQoL), and safety. RBC-TI ≥ 8 weeks was achieved in 26.9% and 2.5% of patients in the lenalidomide and placebo groups, respectively (P 500 mU/mL). At week 12, mean changes in HRQoL scores from baseline did not differ significantly between treatment groups, which suggests that lenalidomide did not adversely affect HRQoL. Achievement of RBC-TI ≥ 8 weeks was associated with significant improvements in HRQoL (P < .01). The most common treatment-emergent adverse events were neutropenia and thrombocytopenia. Lenalidomide yields sustained RBC-TI in 26.9% of RBC transfusion-dependent patients with lower-risk non-del(5q) myelodysplastic syndromes ineligible for or refractory to erythropoiesis-stimulating agents. Response to lenalidomide was associated with improved HRQoL. Treatment-emergent adverse event data were consistent with the known safety profile of lenalidomide. © 2016 by American Society of Clinical Oncology.

  2. Acute Shoulder Injuries in Adults.

    2016-07-15

    Acute shoulder injuries in adults are often initially managed by family physicians. Common acute shoulder injuries include acromioclavicular joint injuries, clavicle fractures, glenohumeral dislocations, proximal humerus fractures, and rotator cuff tears. Acromioclavicular joint injuries and clavicle fractures mostly occur in young adults as the result of a sports injury or direct trauma. Most nondisplaced or minimally displaced injuries can be treated conservatively. Treatment includes pain management, short-term use of a sling for comfort, and physical therapy as needed. Glenohumeral dislocations can result from contact sports, falls, bicycle accidents, and similar high-impact trauma. Patients will usually hold the affected arm in their contralateral hand and have pain with motion and decreased motion at the shoulder. Physical findings may include a palpable humeral head in the axilla or a dimple inferior to the acromion laterally. Reduction maneuvers usually require intra-articular lidocaine or intravenous analgesia. Proximal humerus fractures often occur in older patients after a low-energy fall. Radiography of the shoulder should include a true anteroposterior view of the glenoid, scapular Y view, and axillary view. Most of these fractures can be managed nonoperatively, using a sling, early range-of-motion exercises, and strength training. Rotator cuff tears can cause difficulty with overhead activities or pain that awakens the patient from sleep. On physical examination, patients may be unable to hold the affected arm in an elevated position. It is important to recognize the sometimes subtle signs and symptoms of acute shoulder injuries to ensure proper management and timely referral if necessary.

    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.

  4. Acute Monoarthritis: Diagnosis in Adults.

    Becker, Jonathan A; Daily, Jennifer P; Pohlgeers, Katherine M

    2016-11-15

    Acute monoarthritis can be the initial manifestation of many joint disorders. The most common diagnoses in the primary care setting are osteoarthritis, gout, and trauma. It is important to understand the prevalence of specific etiologies and to use the appropriate diagnostic modalities. A delay in diagnosis and treatment, particularly in septic arthritis, can have catastrophic results including sepsis, bacteremia, joint destruction, or death. The history and physical examination can help guide the use of laboratory and imaging studies. The presence of focal bone pain or recent trauma requires radiography of the affected joint to rule out metabolic bone disease, tumor, or fracture. If there is a joint effusion in the absence of trauma or recent surgery, and signs of infection (e.g., fever, erythema, warmth) are present, subsequent arthrocentesis should be performed. Inflammatory synovial fluid containing monosodium urate crystals indicates a high probability of gout. Noninflammatory synovial fluid suggests osteoarthritis or internal derangement. Pitfalls in the diagnosis and early treatment of acute monoarthritis include failure to perform arthrocentesis, administering antibiotics before aspirating the joint when septic arthritis is suspected (or failing to start antibiotics after aspiration), and starting treatment based solely on laboratory data, such as an elevated uric acid level.

    The diagnosis of acute pyelonephritis in adults is predominantly made by a combination of typical clinical features of flank pain, high temperature and dysuria combined with urinalysis findings of bacteruria and pyuria. Imaging is generally reserved for patients who have atypical presenting features or in those who fail to respond to conventional therapy. In addition, early imaging may be useful in diabetics or immunocompromised patients. In such patients, imaging may not only aid in making the diagnosis of acute pyelonephritis, but more importantly, it may help identify complications such as abscess formation. In this pictorial review, we discuss the role of modern imaging in acute pyelonephritis and its complications. We discuss the growing role of cross-sectional imaging with computed tomography (CT) and novel magnetic resonance imaging (MRI) techniques that may be used to demonstrate both typical as well as unusual manifestations of acute pyelonephritis and its complications. In addition, conditions such as emphysematous and fungal pyelonephritis are discussed. (orig.)

    A 62-year-old man was hospitalized for acute rheumatic fever. He had previously suffered from rheumatic fever at 15 years of age. The rheumatic fever was complicated by carditis, which caused valve disease that required surgical treatment. The incidence of rheumatic fever has decreased in most developed countries with improvements in sanitary conditions. The low incidence of this disease makes a timely and accurate diagnosis difficult. Due to the fact that both the first occurrence and recurrence of acute rheumatic fever can occur in the elderly and adults, this potential disease should not be overlooked when making a differential diagnosis.

    (1) Acute otitis media is likely in adults with recent-onset otalgia, fever, and a bulging eardrum on otoscopy. Management is similar to that in children: no antibiotics in the first instance, then amoxicillin later if antibiotic therapy is needed. (2) Otitis media with a perforated eardrum, and evidence of pus must be distinguished from external otitis. In patients with otitis media and a perforated eardrum, the commonest bacterial isolates are staphylococci, pseudomonas and pneumococci. (3) If antibiotics are prescribed the choice of agent is based on individual clinical findings and underlying health status.

    Annette Fox

    Full Text Available BACKGROUND: 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. METHODS AND FINDINGS: 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. CONCLUSION: 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.

    The t(8;21)(q22;q22) translocation is specifically observed in acute myeloid leukemia (AML) M2 subtype, whereas del(5q) is one of the most common cytogenetic aberrations in myelodysplastic syndromes (MDS). Thus, t(8;21)(q22;q22) and del(5q) appear to be mutually exclusive, and the association between them has not been characterized yet. Here, we report an 81-year-old woman with coexistent t(8;21)(q22;q22) and del(5q) at initial diagnosis. The bone marrow was infiltrated with 18.4% myeloblasts, and showed marked myeloid and erythroid dysplasia. Myeloblasts were positive for CD19 and CD56 as well as CD13, CD33, CD34 and HLA-DR. G-banding and spectral karyotyping showed 46,XX,del(5)(q?),t(8;21)(q22;q22)[18]/46,XX[2]. Both del(5)(q?) and t(8;21)(q22;q22) were present in a single clone. Fluorescence in situ hybridization (FISH) on metaphase spreads detected a RUNX1/RUNX1T1 fusion signal on the der(8)t(8;21)(q22;q22), and confirmed deletion of CSF1R signaling at 5q33-q34 on the del(5)(q?). Furthermore, FISH on interphase nuclei revealed that the RUNX1/RUNX1T1 fusion signal and deletion of CSF1R signaling were found in 66.0% and 58.0% of interphase cells, respectively, suggesting that del(5)(q?) occurred in cells with RUNX1/RUNX1T1. These results indicated a diagnosis of AML with t(8;21)(q22;q22)/RUNX1/RUNX1T1 rather than MDS, even though the percentage of bone marrow myeloblasts was less than 20%. Based on these findings, together with those of other reported cases, del(5q) seems to be an extremely rare but recurrent secondary aberration in AML with t(8;21)(q22;q22).

    Interest has recently been paid to adolescents and young adults with acute lymphoblastic leukemia, particularly because all reports so far published indicate that these patients have a better outcome when treated with pediatric rather than adult therapeutic protocols. There are different biological subtypes of acute lymphoblastic leukemia with distinct features and prognoses; the distribution of these subtypes is not well known among adolescents. We, therefore, studied acute lymphoblastic leukemia in adolescents and young adults aged 10 to 25 years in Finland. This population-based study included 225 consecutive patients aged 10-25 years diagnosed with acute lymphoblastic leukemia during 1990-2004. One hundred and twenty-eight patients (10-16 years) were treated with pediatric Nordic (NOPHO) protocols, and 97 patients (17-25 years) with Finnish Leukemia Group National protocols. We characterized the biological subtypes, clinical features and outcome of these patients. For the whole cohort, the remission rate was 96%, 5-year event-free survival 62% and overall survival 72%. The 5-year event-free survival was 67% for the pediatric treatment group and 60% for the adult treatment group (p=n.s.). Patients with inferior outcome were those with a white blood cell count >or= 100 x 10(9)/L, the Philadelphia chromosome and MLL. Good prognostic features were TEL-AML1, hyperdiploidy, and pediatric intermediate risk stratification. Unlike all previous studies, we found that the outcome of adolescents and young adults with acute lymphoblastic leukemia treated with pediatric or adult therapeutic protocols was comparable. The success of the adult acute lymphoblastic leukemia therapy emphasizes the benefit of central referral of patients to academic centers and adherence to research protocols.

    Problems of maintaining therapy for acute myelocytic leukemias in adults are discussed. The analysis of the maintaining therapy in 22 patients affected with an acute myelocytic leukemia and living for more than 6 months revealed that the interval therapy with a high dosage of cytostatic combinations in the sense of the COAP scheme is preferable compared with the daily administration of 6-mercaptopurin, in addition methotrexate twice a week. Reasons for this are discussed.

    Acute mesenteric ischemia is commonly seen in old patients. This study was undertaken to show that mesenteric ischemia might be seen in individuals under 40 years of age and that its diagnosis is challenging. Twenty-six patients with acute mesenteric ischemia under the age of 40 were studied. The main symptom on admission was abdominal pain. Symptom duration varied between 12 h and 5 days. The medical history of the patients revealed that 9 had no previous diseases. Other 17 had predisposing factors in the first evaluation. None of the patients had any history of narcotic or drug abuse. Ten patients presented with signs and symptoms of sepsis and septic shock. Preoperative diagnosis was acute intestinal ischemia only in 6 patients. Preoperatively, all the patients had intestinal or colonic ischemia and necrosis; one had additional ischemia of the liver, stomach, duodenum, and pancreas. Six patients had massive intestinal necrosis. The overall postoperative complication and overall mortality rates were 61.5 and 26.9 %, respectively. Complications and mortality were determined to be associated with previous pulmonary disease, acidosis, presence of septic shock, acute renal failure, extent of the ischemia and extent of resection, second look operations, previous cardiac events, and the kind of affected bowel (colon involvement).

    A growing number of reports state that regular exercise enhances brain function in older adults. Recently a functional near-infrared spectroscopy (fNIRS) study revealed that an acute bout of moderate exercise enhanced activation of the left dorsolateral prefrontal cortex (L-DLPFC) associated with Stroop interference in young adults. Whether this acute effect is also applicable to older adults was examined. Sixteen older adults performed a color-word matching Stroop task before and after 10 minutes of exercise on a cycle ergometer at a moderate intensity. Cortical hemodynamics of the prefrontal area was monitored with a fNIRS during the Stroop task. We analyzed Stroop interference (incongruent-neutral) as Stroop performance. Though activation for Stroop interference was found in the bilateral prefrontal area before the acute bout of exercise, activation of the right frontopolar area (R-FPA) was enhanced after exercise. In the majority of participants, this coincided with improved performance reflected in Stroop interference results. Thus, an acute bout of moderate exercise improved Stroop performance in older adults, and this was associated with contralateral compensatory activation.

  18. Current Concepts in Adult Acute Rhinosinusitis.

    2016-07-15

    Acute rhinosinusitis is one of the most common conditions that physicians treat in ambulatory care. Most cases of acute rhinosinusitis are caused by viral upper respiratory infections. A meta-analysis based on individual patient data found that common clinical signs and symptoms were not effective for identifying patients with rhinosinusitis who would benefit from antibiotics. C-reactive protein and erythrocyte sedimentation rate are somewhat useful tests for confirming acute bacterial maxillary sinusitis. Four signs and symptoms that significantly increase the likelihood of a bacterial cause when present are double sickening, purulent rhinorrhea, erythrocyte sedimentation rate greater than 10 mm per hour, and purulent secretion in the nasal cavity. Although cutoffs vary depending on the guideline, antibiotic therapy should be considered when rhinosinusitis symptoms fail to improve within seven to 10 days or if they worsen at any time. First-line antibiotics include amoxicillin with or without clavulanate. Current guidelines support watchful waiting within the first seven to 10 days after upper respiratory symptoms first appear. Evidence on the use of analgesics, intranasal corticosteroids, and saline nasal irrigation for the treatment of acute rhinosinusitis is poor. Nonetheless, these therapies may be used to treat symptoms within the first 10 days of upper respiratory infection. Radiography is not recommended in the evaluation of uncomplicated acute rhinosinusitis. For patients who do not respond to treatment, computed tomography of the sinuses without contrast media is helpful to evaluate for possible complications or anatomic abnormalities. Referral to an otolaryngologist is indicated when symptoms persist after maximal medical therapy and if any rare complications are suspected.

    Full Text Available AML is an aggressive hematological malignancy with highest incidence in the older adults. The adverse features of AML in the elderly, and the frailties and comorbidities frequently present in them, make their management a particularly difficult therapeutic challenge. In this context, it is important to assess carefully patient- as well as disease-associated prognostic features with validated tools. The fittest patients should be considered for curative therapy, such as bone marrow transplantation, whereas low intensity options may be more appropriate for frail patients. Here we review how to assess patients with elderly AML and the treatments options available for them.

    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.

    Eighty-five consecutive patients with acute lymphoblastic leukaemia (ALL), having a median age of 24 years (range 10-69 years), underwent induction and consolidation chemotherapy with weekly parenteral vincristine, Adriamycin, l-asparaginase and daily oral prednisone (VAAP), followed by standard (CNS) prophylaxis. Maintenance therapy was given for 3 years and consisted of daily 6-mercaptopurine, weekly methotrexate and monthly intrathecal therapy, with drug intensification comprising either vincristine, Adriamycin and l-asparaginase (VAA) or cyclophosphamide, vincristine, cytosine arabinoside and prednisone (COAP). Complete remission (CR) was obtained in 59 patients (69%) and only the French-American-British (FAB) L1 morphology was a significant predictive factor (P = 0.048). Twenty-three patients failed to achieve CR and of these 12 had primary drug resistance. Median follow-up is currently 260 weeks, median predicted survival of all patients is 58 weeks and for those who achieved CR it is 104 weeks. Median duration of CR is 70 weeks. Of the prognostic factors for survival, only FAB L1 subtype was significant. Bone marrow relapses occurred in 29 patients, and of these 9 (31%) achieved CR. There has been CNS relapse in two patients and both have died. Eleven patients continue in CR off therapy, with a median of 152 weeks. This regimen is effective, with acceptable toxicity, and a number of patients are potentially cured. The incidence of resistant and relapsing disease is an argument for further intensifying both induction and postinduction therapy.

    Hainer, Barry L; Matheson, Eric M

    2013-05-15

    Approximately one-half of the adult population worldwide is affected by a headache disorder. The International Headache Society classification and diagnostic criteria can help physicians differentiate primary headaches (e.g., tension, migraine, cluster) from secondary headaches (e.g., those caused by infection or vascular disease). A thorough history and physical examination, and an understanding of the typical features of primary headaches, can reduce the need for neuroimaging, lumbar puncture, or other studies. Some red flag signs and symptoms identified in the history or during a physical examination can indicate serious underlying pathology and will require neuroimaging or other testing to evaluate the cause of headache. Red flag signs and symptoms include focal neurologic signs, papilledema, neck stiffness, an immunocompromised state, sudden onset of the worst headache in the patient's life, personality changes, headache after trauma, and headache that is worse with exercise. If an intracranial hemorrhage is suspected, head computed tomography without contrast media is recommended. For most other dangerous causes of headache, magnetic resonance imaging or computed tomography is acceptable.

    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

    INTRODUCTION: 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...... culture for bacterial pathogens. RESULTS: 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. CONCLUSION: Rotavirus is the second-most frequently identified pathogen in adults...

    Full Text Available Acute cholecystitis is a major health problem. There are multiple etiologies to be considered and early recognition of the condition is important to optimize management and outcome. We report the first case in the medical literature of symptomatic acute cholecystitis triggered by ceftriaxone-associated gallbladder sludge formation and, importantly, solid ceftriaxone gallstone formation in an adult patient with underlying mineral and pigment cholecystolithiasis, necessitating cholecystectomy. This case serves as a reminder for physicians to keep this uncommon cause of cholecystolithiasis and cholecystitis in mind in patients who receive prolonged ceftriaxone therapy. These patients should be cautioned to promptly report to their physicians any signs or symptoms of cholecystitis in order to ensure timely and appropriate evaluation.

    Full Text Available Background : Acute onset fever with altered mentation is a common problem encountered by the physician practicing in tropical countries. Central nervous system (CNS infections are the most common cause resulting in fever with altered mentation in children. Aim : In this study, we have tried to analyze the cause of encephalopathy following short febrile illness in adults presenting to a tertiary care center in Northwestern part of India. Setting and Design : A prospective observational study carried out in a tertiary care center in the Northwestern India over a period of 1 year. Material and Methods : A total of 127 patients with fever of less than 2 weeks duration along with alteration in mentation were studied prospectively over a period of 12 months. The demographic variables were recorded in detail. In addition to routine investigations, cerebrospinal fluid analysis, noncontrast- and contrast-enhanced computed tomography, along with magnetic resonance imaging were performed in all the subjects. Statistical Analysis : The results were analyzed using SPSS statistical software. The values were expressed as mean with standard deviation for contiguous variable as percentage for the others. Results and Conclusion : Out of these, 70% had primary CNS infection as the etiology. A total of 33% patients had meningitis, 29.9% had evidence of meningoencephalitis, and 12.7% were diagnosed as sepsis-associated encephalopathy. These were followed by cerebral malaria, leptospirosis, and brain abscess as the cause of febrile encephalopathy in adults. Among the noninfectious causes, acute disseminated encephalomyelitis, cortical venous thrombosis, and neuroleptic malignant syndrome were documented in 2.36% each. In 11% of the patients, the final diagnosis could not be made in spite of the extensive investigations. Our study demonstrates that acute febrile encephalopathy in adults is a heterogeneous syndrome with primary CNS infections being the commonest

    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. Keywords: probiotics, treatment efficacy, acute diarrhea, adults.     Efektivitas Probiotik pada Orang Dewasa dengan Diare:  Sebuah Laporan Kasus Berbasis Bukti   Abstrak Diare merupakan masalah kesehatan global dengan angka morbiditas dan mortalitas yang tinggi.

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.

    The transfer of acutely ill adults who were transported between hospitals by the Scottish Ambulance Service was audited in order to determine the number of transfers and to quantify the incidence of adverse events. Patients over 16 years of age requiring intervention/vital signs monitoring during transfer or a nursing/medical escort from the outset were defined as acutely ill adults. Three thousand and forty-eight audit forms were received, of which 2396 were suitable for inclusion in the audit. Transfers primarily occurred for specialist management (1580; 66%) or specialist investigation (550; 23%). Clinicians escorted 825 (34%) patients and were away from their hospital a median (IQR [range]) of 2 h (01:24-3:30 [00:05-17:33]) h:min Clinical intervention was required in 84 transfers (4%). The median (IQR [range]) time for 248 transfers (10.3%) requiring assisted ventilation was 28 min (00:17-00:50 [00:04-02:55]). The incidence of unsecured medical equipment (in escorted transfers only) was significantly lower in dedicated transport teams (2/205, 1%) vs non-dedicated (113/620, 18%; p = 0.004). Medical equipment failures were less common in the transfer of patients requiring assisted ventilation (1/156, 0.6% vs 9/97, 9%; p = 0.001).

    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 ({kappa} = 0.51) and fair ({kappa} = 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.

    Introduction The acute abdomen is the main term for an at first unclear emergency situation of the abdominal cavity. The acute abdomen belongs to the three most important reasons for the admission of patients into the emergency room. Further, this illness ranks 40% of all consultations in the ambulant care sector. The acute abdomen requires an early and direct diagnosis because of its potential of having a life threatening differential diagnosis. This HTA report aimed to assess the ultrasound diagnosis of the acute abdomen considering children and adults. This will be done from a medical and economic perspective. The differential diagnosis respectively the cause of the acute abdomen binds high direct treatment costs, especially in the stationary sector. Ultrasound diagnosis is a procedure that plays a big part in the differential diagnosis process and it is widely used in practise. Other research methods of diagnosing acute abdominal illness are: clinical examinations with inspection and palpation, surgical exploration and laparocopy as well as computer tomography and x-ray examination. Objectives The main objective of this HTA report is to assess what significance sonography should have within the examination strategy of the acute abdomen from the medical and economical view. Second, this HTA report will evaluate under which circumstances the ultrasonographic diagnosis of the acute abdomen, considering medical and economical quality classifications, is the alternative of choice to comparable diagnostic measures. Methods The target population this HTA report is aimed at are children and adults with acute abdomen or embedded differential diagnosis. A systematic literature search was conducted covering all relevant medical and HTA-databases. Furthermore, handsearch was conducted inside of the known data bases of HTA-institutions as well as from medical and economical journals. The following databases were searched in cooperation with DIMDI to identify relevant

    The net benefits of induction therapy for older adults with acute myeloid leukemia (AML) remain controversial. Because AML in older adults is a heterogeneous disease, it is important to identify those who are unlikely to benefit from induction therapy based on information available at the initial assessment. We used next-generation sequencing to analyze TP53 mutation status in AML patients aged 60 years or older, and evaluated its effects on outcomes. TP53 mutations were detected in 12 of 77 patients (16 %), and there was a significant association between TP53 mutations and monosomal karyotype. Patients with TP53 mutations had significantly worse survival than those without (P = 0.009), and multivariate analysis identified TP53 mutation status as the most significant prognostic factor for survival. Neverthelsess, TP53-mutated patients had a 42 % chance of complete remission and a median survival of 8.0 months, which compares favorably with those who did not undergo induction therapy, even in the short term. These results suggest that screening for TP53 mutations at diagnosis is useful for identifying older adults with AML who are least likely to respond to chemotherapy, although the presence of this mutation alone does not seem to justify rejecting induction therapy.

    We review recent published data on demographics, causes, diagnoses, treatment, and outcome of acute kidney injury (AKI) in Africa. 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.

    Limited research indicates positive affective change following acute bouts of exercise, but whether this improved affect among younger subjects may be generalized to older individuals is not known. The present study, then, examined the effects of a single bout of physical activity among older participants. 16 trained women (Mage = 64.5 +/- 7.6 yr.) completed an abbreviated Profile of Mood States prior to and immediately following a 75-min. session of aerobic line dancing. A series of one-way analyses of variance with repeated measures were used to examine differences between pre- and posttest subscores on mood states. Significant decreases following exercise in scores on Tension, Depression, Fatigue, and Anger and a significant increase in scores on Vigor relative to preexercise (control) scores were found. Global mood was significantly improved after the exercise session. No significant difference was found between pre- and postexercise measures of Confusion. Previous findings of significant improvements in affect immediately after an acute bout of exercise may be generalized to older adults. Repetition with a nonexercised control group is desirable.

    The distinct nature of acute lymphoblastic leukemia (ALL) in adults, evidenced by inferior treatment outcome and different genetic landscape, mandates specific studies of disease-initiating mechanisms. In this study, we used NOD/LtSz-scid IL2Rγ nullc (NSG) mouse xenotransplantation approaches to elucidate leukemia-initiating cell (LIC) biology in primary adult precursor B (pre-B) ALL to optimize disease modeling. In contrast with xenografting studies of pediatric ALL, we found that modification of the NSG host environment using preconditioning total body irradiation (TBI) was indispensable for efficient engraftment of adult non-t(4;11) pre-B ALL, whereas t(4;11) pre-B ALL was successfully reconstituted without this adaptation. Furthermore, TBI-based xenotransplantation of non-t(4;11) pre-B ALL enabled detection of a high frequency of LICs (<1:6900) and permitted frank leukemic engraftment from a remission sample containing drug-resistant minimal residual disease. Investigation of TBI-sensitive stromal-derived factor-1/chemokine receptor type 4 signaling revealed greater functional dependence of non-t(4;11) pre-B ALL on this niche-based interaction, providing a possible basis for the differential engraftment behavior. Thus, our studies establish the optimal conditions for experimental modeling of human adult pre-B ALL and demonstrate the critical protumorogenic role of microenvironment-derived SDF-1 in regulating adult pre-B LIC activity that may present a therapeutic opportunity.

    Acute pharyngitis in adults is one of the most common infectious diseases seen in general practitioners' consultations. Viral aetiology is the most common. Among bacterial causes, the main agent is Streptococcus pyogenes or group A β-haemolytic streptococcus (GABHS), which causes 5%-30% of the episodes. In the diagnostic process, clinical assessment scales can help clinicians to better predict suspected bacterial aetiology by selecting patients who should undergo a rapid antigen detection test. If these techniques are not performed, an overdiagnosis of streptococcal pharyngitis often occurs, resulting in unnecessary prescriptions of antibiotics, most of which are broad spectrum. Consequently, management algorithms that include the use of predictive clinical rules and rapid tests have been set up. The aim of the treatment is speeding up symptom resolution, reducing the contagious time span and preventing local suppurative and non-suppurative complications. Penicillin and amoxicillin are the antibiotics of choice for the treatment of pharyngitis. The association of amoxicillin and clavulanate is not indicated as the initial treatment of acute infection. Neither are macrolides indicated as first-line therapy; they should be reserved for patients allergic to penicillin. The appropriate diagnosis of bacterial pharyngitis and proper use of antibiotics based on the scientific evidence available are crucial. Using management algorithms can be helpful in identifying and screening the cases that do not require antibiotic therapy.

    A statistical analysis of the prognostic significance of eight pretreatment variables was undertaken for 71 previously untreated adult patients with acute leukemia seen at M.D. Anderson Hospital over a 5 1/2-year period. None of the patients had received any prior therapy. Nearly all of the patients (68 of the 71) were treated with 4- or 5-day courses of arabinosyl-cytosine alone or in combination with cyclophosphamide, vincristine (oncovin) and prednisone (COAP). The pretreatment variables studied were age at diagnosis, the percent labeling index of the bone marrow leukemic cells, diagnosis, the highest temperature prior to start of treatment, the marrow clot section cellularity and smear differential percent of blasts, percent absolute marrow leukemic cell infiltrate and absolute number of blasts X 10(3)/mm3 in the peripheral blood. Fifty-one patients had acute myeloblastic leukemia (AML) and 20 patients had acute lymphoblastic leukemia (ALL). Using a statistical regression model approach, the only variables found to be of significant prognostic importance with respect to the probability of complete remission for AML patients were the pretreatment percent labeling index, the age of the patient and the highest temperature prior to start of treatment. Unlike AML, the initial percent labeling index did not appear to be of prognostic significance for ALL patients. AML patients with high labeling indices (larger than or equal to 9%) and young patients in general (especially those less than 40 years old) had the best remission rates. With respect to the length of complete remission and survival for all patients, the only important variables were the pretreatment percent labeling index and the age of the patient, respectively. Once in complete remission, an initially high labeling index was an unfavorable sign with respect to length of remission, regardless of the patient's diagnosis. The results of this study are supportive of studies in experimental systems

    Use of topical NSAIDs to treat acute musculoskeletal conditions has become widely accepted because they can provide pain relief without associated systemic adverse events. This review is an update of 'Topical NSAIDs for acute pain in adults' originally published in Issue 6, 2010. To determine the efficacy and safety of topically applied NSAIDs in acute musculoskeletal pain in adults. We searched the Cochrane Register of Studies Online, MEDLINE, and EMBASE to February 2015. We sought unpublished studies by asking personal contacts and searching online clinical trial registers and manufacturers websites. For the earlier review, we also searched our own in-house database and contacted manufacturers. We included randomised, double-blind, active or placebo (inert carrier)-controlled trials in which treatments were administered to adults with acute pain resulting from strains, sprains or sports or overuse-type injuries (twisted ankle, for instance). There had to be at least 10 participants in each treatment arm, with application of treatment at least once daily. Two review authors independently assessed studies for inclusion, and extracted data. We used numbers of participants achieving each outcome to calculate the risk ratio and numbers needed to treat for an additional beneficial outcome (NNT) or additional harmful outcome (NNH) compared with placebo or other active treatment. We reported 95% confidence intervals (CI). We were particularly interested to compare different formulations (gel, cream, plaster) of individual NSAIDs. For this update we added 14 new included studies (3489 participants), and excluded four studies. We also identified 20 additional reports of completed or ongoing studies that have not been published in full. The earlier review included 47 studies.This update included 61 studies. Most compared topical NSAIDs in the form of a gel, spray, or cream with a similar topical placebo; 5311 participants were treated with a topical NSAID, 3470 with placebo

    Motor activity and neuromotor function were examined in adult CD rats exposed to either carbaryl or propoxur, and behavioral effects were compared with the time course of cholinesterase inhibition. Rats received an IP injection of either 0, 2, 4, 6 or 8 mg/kg propoxur or 0, 4, 8, 16 or 28 mg/kg carbaryl in corn oil 20 min before testing. All doses of propoxur reduced 2 hr activity in a figure-eight maze, and crossovers and rears in an open field. For carbaryl, dosages of 8, 16 and 28 mg/kg decreased maze activity whereas 16 and 28 mg/kg reduced open field activity. In order to determine the time course of effects, rats received a single IP injection of either corn oil, 2 mg/kg propoxur or 16 mg/kg carbaryl, and were tested for 5 min in a figure-eight maze either 15, 30, 60, 120 or 240 min post-injection. Immediately after testing, animals were sacrificed and total cholinesterase was measured. Maximum effects of propoxur and carbaryl on blood and brain cholinesterase and motor activity were seen within 15 min. Maze activity had returned to control levels within 30 and 60 min whereas cholinesterase levels remained depressed for 120 and 240 min for propoxur and carbaryl, respectively. These results indicate that both carbamates decrease motor activity, but behavioral recovery occurs prior to that of cholinesterase following acute exposure.

    Liver abnormalities in the course of Adult Onset Still's Disease (AOSD), both in form of hepatomegaly and elevation of hepatic enzymes, have been reported in up to three-quarts of the affected patients. These abnormalities may reflect disease activity or may be induced by drugs. Only in a few of this patients a liver biopsy was performed. However liver histology has shown, generally, non specific abnormalities or even normal pictures. We have recently observed a 47-year-old woman with a febrile illness started five months before, who after pertinent investigation was diagnosed as AOSD (according to criteria of Yamaguchi et al.). Apart from laboratory findings characteristic of an inflammatory disease, in absence of drug therapies the biochemical data showed raised levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and aminoglutamil transferase. Serological tests for either viral hepatitis viruses (HAV, HBV, HCV) or other viruses were negative. Ultrasonographic examination of gallbladder and bile ducts did not find gallstones or other abnormalities. A liver biopsy was performed, which histopathologic examination showed moderate fatty methamorphosis with focal areas of hepatocellular swelling with minimal necrosis, mild Kuppfer cell hyperplasia, portal and sinusoidal infiltrates of mononuclear cells. This picture consisted with the diagnosis of an acute unspecific reactive hepatitis.

    Acetaminophen (APAP) overdose induces acute liver injury. The aim of the present study was to analyze the difference of susceptibility between immature and adult mice to APAP-induced acute liver injury. Weanling immature and adult mice were injected with APAP (300 mg/kg). As expected, immature mice were more susceptible than adult mice to APAP-induced acute liver injury. APAP-evoked hepatic c-Jun N-terminal kinase phosphorylation was stronger in immature mice than in adult mice. Hepatic receptor-interacting protein (RIP)1 was obviously activated at APAP-exposed immature and adult mice. Interestingly, hepatic RIP3 activation was more obvious in APAP-treated immature mice than adult mice. Although there was no difference on hepatic GSH metabolic enzymes between immature and adult mice, immature mice were more susceptible than adult mice to APAP-induced hepatic GSH depletion. Of interest, immature mice expressed a much higher level of hepatic Cyp2e1 and Cyp3a11 mRNAs than adult mice. Correspondingly, immature mice expressed a higher level of hepatic CYP2E1, the key drug metabolic enzyme that metabolized APAP into the reactive metabolite NAPQI. These results suggest that a higher level of hepatic drug metabolic enzymes in immature mice than adult mice might contribute to the difference of susceptibility to APAP-induced acute liver injury.

    Clinical manifestations of intestinal yersiniosis include enterocolitis, mesenteric adenitis, and terminal ileitis presenting with fever, right lower quadrant pain, and leukocytosis. According to a previous Korean study in 1997, Yersinia was revealed in two among 15 adult patients with mesenteric adenitis (13%). However, recent reports on the prevalence of Yersinia infection in adult patients are few. The aim of this study was to investigate the prevalence of Yersinia infection in adult patients with acute right lower quadrant pain. Adult patients (>18 years) who visited Eulji medical center, due to acute right lower quadrant pain were enrolled prospectively from December 2007 to July 2009. Abdominal CT, stool culture, serologic test for Yersinia, and Widal test were performed. Among 115 patients, 5 patients were excluded due to positive Widal test or salmonella culture. In 110 patients, abdominal CT showed right colitis in 20 (18.2%), terminal ileitis in 16 (14.5%), mesenteric adenitis in 13 (11.8%), acute appendicitis in 10 (9.1%), acute diverticulitis in 7 (6.4%), non specific mucosal edema in 36 (32.7%) and no specific lesion in 8 (7.3%). Two (1.8%) of the 110 patients had antibodies to Yersinia. One patient showed acute enteritis and the other patient was diagnosed with acute appendicitis and underwent appendectomy. No Yersinia species were grown on stool or tissue culture. Nowadays, among adult Korean patients presenting with acute right lower quadrant pain, there have been few incidences of Yersinia infection.

    Bacillus cereus, which used to be considered non-pathogenic, was isolated from the blood of a patient with acute leukemia who was receiving intensive chemotherapy. Fatal bacteremia developed with a clinical syndrome of acute gastroenteritis, followed by both meningoencephalitis with subarachnoid hemorrhage and multiple liver abscesses probably caused by infective vasculitis. Surveillance stool cultures revealed colonization with the organism prior to the onset of diarrhea, and repetitive blood cultures were found to be positive. Thus, this case suggested some new important clinicopathologic features of true B. cereus bacteremia complicating acute leukemia.

    Dipyrone (metamizole) is a nonsteroidal anti-inflammatory drug used in some countries to treat pain (postoperative, colic, cancer, and migraine); it is banned in other countries because of an association with life-threatening blood disorders. This review replaces a 2010 Cochrane review that has been withdrawn. To assess the analgesic efficacy and associated adverse events of single dose dipyrone for moderate to severe acute 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, and LILACS to 11 August 2015; the Oxford Pain Relief Database; two clinical trial registries; and the reference lists of articles. We included randomised, double-blind, placebo-controlled trials of single dose dipyrone for relief of established moderate to severe postoperative pain in adults. We accepted oral, rectal, intramuscular, and intravenous routes of administration. Two review authors independently considered studies for inclusion in the review, assessed risk of bias, and extracted data. We used summed total pain relief or pain intensity difference (TOTPAR or SPID) over four to six hours to calculate the number of participants achieving at least 50% pain relief. From derived results, we calculated the risk ratio and number needed to treat for an additional beneficial outcome (NNT), with 95% confidence intervals (CI), for one participant to experience at least 50% pain relief over four to six hours compared to placebo. We looked at use of rescue medication and time to use of rescue medication as additional measures of efficacy. We also looked for information on adverse events and withdrawals. We included eight studies, involving 809 participants, comparing oral dipyrone 500 mg (143 participants), oral dipyrone 1000 mg (57 participants), and intramuscular dipyrone 2000 mg (35 participants) with

    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.

    To investigated the relationship between CpG island methylator phenotype (CIMP) and prognosis in adults with acute leukemia. Bone marrow samples from 53 acute myeloid leukemia and 50 acute lymphoblastic leukemia patients were collected. The methylation status of 18 tumor suppressor genes was determined using methylation-specific polymerase chain reaction. Greater than 30% of acute leukemia patients had methylated p15, p16, CDH1, CDH13, RUNX3, sFRP1, ID4, and DLC-1 genes; methylation of ≥4 were defined as CIMP positive. Age, type of leukemia, white blood cell count, and CIMP status were significantly associated with recurrence-free survival (RFS) and overall survival (OS) (P acute leukemia.

    The present study investigated the effects of acute aerobic exercise on cognitive brain functions of older adults. Twenty-four males (12 older and 12 younger adults) performed a modified flanker task during a baseline session (no exercise) and after light and moderate cycling exercise in counterbalanced order on different days while measures of task performance and the P3 component of an event-related brain potential were collected. The results indicated that, for both age groups, reaction time following moderate exercise was shorter relative to the other sessions, and P3 latencies following both light and moderate exercise were shorter compared with the baseline session. In contrast, P3 amplitude increased only following moderate exercise in younger adults. These findings suggest that light and moderate exercises improve cognitive function across the adult lifespan, although the mechanisms underlying the effects of observed acute aerobic exercise on cognitive function may be age dependent.

    Background The epidemiologic characteristics of children and young adults with acute kidney injury have been described in single-center and retrospective studies. We conducted a multinational, prospective study involving patients admitted to pediatric intensive care units to define the incremental risk of death and complications associated with severe acute kidney injury. Methods We used the Kidney Disease: Improving Global Outcomes criteria to define acute kidney injury. Severe acute kidney injury was defined as stage 2 or 3 acute kidney injury (plasma creatinine level ≥2 times the baseline level or urine output <0.5 ml per kilogram of body weight per hour for ≥12 hours) and was assessed for the first 7 days of intensive care. All patients 3 months to 25 years of age who were admitted to 1 of 32 participating units were screened during 3 consecutive months. The primary outcome was 28-day mortality. Results A total of 4683 patients were evaluated; acute kidney injury developed in 1261 patients (26.9%; 95% confidence interval [CI], 25.6 to 28.2), and severe acute kidney injury developed in 543 patients (11.6%; 95% CI, 10.7 to 12.5). Severe acute kidney injury conferred an increased risk of death by day 28 after adjustment for 16 covariates (adjusted odds ratio, 1.77; 95% CI, 1.17 to 2.68); death occurred in 60 of the 543 patients (11.0%) with severe acute kidney injury versus 105 of the 4140 patients (2.5%) without severe acute kidney injury (P<0.001). Severe acute kidney injury was associated with increased use of mechanical ventilation and renal-replacement therapy. A stepwise increase in 28-day mortality was associated with worsening severity of acute kidney injury (P<0.001 by log-rank test). Assessment of acute kidney injury according to the plasma creatinine level alone failed to identify acute kidney injury in 67.2% of the patients with low urine output. Conclusions Acute kidney injury is common and is associated with poor outcomes, including increased

    Isolated left ventricular noncompaction in adults is uncommon. The most frequent clinical manifestations are heart failure due to left ventricular systolic dysfunction and supraventricular and ventricular arrhythmias, which may be sustained and associated with sudden death. Thromboembolic complications are also possible. We report the case of an adult patient with isolated left ventricular noncompaction who came to our observation because of acute cerebral ischemia, an initial presentation of the disease only rarely described.

    Full Text Available Michael E RyttingDepartment of Pediatrics and Leukemia, University of Texas MD Anderson Cancer Center, Houston, TX, USAAbstract: Asparaginase preparations deplete asparagine in acute lymphoblastic leukemia (ALL blasts. Asparaginase in its various forms is an important component of treatment regimens for pediatric ALL. Recently, interest and use of asparaginase in adult patients with ALL has increased, particularly in young adults. There is much less information on asparaginase use and toxicity in adult compared with pediatric populations. This review surveys prior published studies of the three most commonly used asparagine preparations as used in adult patients, and discusses important toxicities encountered in adult patients who receive asparaginase preparations.Keywords: asparaginase, leukemia, adults, children

    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.

    To describe the cognitive, functional, and nutritional features of patients admitted to a Special Acute Care Unit (SACU) for elderly patients with Alzheimer's disease (AD). One-year observational study of patients with AD and other related disorders hospitalized in the SACU, Department of Geriatrics, Toulouse university Hospital during 2005. A comprehensive neurocognitive and non-cognitive geriatric assessment was performed. Data on full clinical evaluation, nutritional status, activities of daily living (ADL), gait and balance disturbance, behavioural and psychological symptoms (BPSD), and sociodemographics were recorded. Four-hundred and ninety-two patients were assessed. Their mean age was 81.1+/-7.7, the mean length of stay was 10.7+/-6.3 days, 62% were female, 63.9% were admitted from their own home and 30.4% from a nursing home. Eighty percent of patients had probable Alzheimer's disease or mixed dementia, less than 20% had other causes of dementia. Results of their comprehensive assessment showed a mean mini-mental state examination of 14.5+/-7.4; a mean total ADL score of 3.7+/-1.7. Seventy-seven percent had gait or balance disturbances; 90% of patients presented an unsatisfactory nutritional status. The most common reason for admission was BPSD. AD complications are responsible for many acute admissions. Elderly patients suffering from dementia represent a population with unique clinical characteristics. Further randomised clinical trials are needed to evaluate the effectiveness of Special Acute Care Units for patients with AD and other related disorders. Copyright (c) 2007 John Wiley & Sons, Ltd.

    Source monitoring refers to cognitive processes involved in making attributions about the origins of memories, knowledge, and beliefs. One particular type of source monitoring with ample practical significance is reality monitoring, i.e., the ability to discriminate between internally vs. externally generated memories. Abundant evidence indicates that exposure to acute stress enhances declarative memory consolidation. To date, no study has looked at whether exposure to acute stress during the consolidation phase may promote reality monitoring performance. The authors examined this by administering cold pressor stress (CPS) or a control procedure to participants (N = 80) after they had either performed or only imagined performing simple motor acts, and assessing reality monitoring 24 h later. When compared with the control condition, CPS significantly elevated salivary free cortisol concentrations and enhanced reality monitoring. Stress-induced cortisol responses, however, were found not to be related to improved reality monitoring performance. Our findings are consistent with the view that post-learning stress hormone-related activity may modulate source memory consolidation.

    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.)

    The purpose of this review is to examine the indications of extracorporeal membrane oxygenation (ECMO) for severe acute respiratory distress syndrome (ARDS). This technique of oxygenation has significantly increased worldwide with the H1N1 flu pandemic. The goal of ECMO is to maintain a safe level of oxygenation and controlled respiratory acidosis under protective ventilation. The enthusiasm for ECMO should not obscure the consideration for potential associated complications. Before widespread diffusion of ECMO, new trials should test the efficacy of early initiation or CO2 removal in addition to, or even as an alternative to mechanical ventilation for severe ARDS.

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

    Acute 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.

    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.

    In this study, we aimed to investigate the pathways of recognition of acute lymphoblastic leukemia blasts by natural killer cells and to verify whether differences in natural killer cell activating receptor ligand expression among groups defined by age of patients, or presence of cytogenetic/molecular aberrations correlate with the susceptibility to recognition and killing. We analyzed 103 newly diagnosed acute lymphoblastic leukemia patients: 46 adults and 57 children. Pediatric blasts showed a significantly higher expression of Nec-2 (P=0.03), ULBP-1 (P=0.01) and ULBP-3 (P=0.04) compared to adult cells. The differential expression of these ligands between adults and children was confined to B-lineage acute lymphoblastic leukemia with no known molecular alterations. Within molecularly defined subgroups of patients, a high surface expression of NKG2D and DNAM1 ligands was found on BCR-ABL(+) blasts, regardless of patient age. Accordingly, BCR-ABL(+) blasts proved to be significantly more susceptible to natural killer-dependent lysis than B-lineage blasts without molecular aberrations (P=0.03). Cytotoxic tests performed in the presence of neutralizing antibodies indicated a pathway of acute lymphoblastic leukemia cell recognition in the setting of the Nec-2/DNAM-1 interaction. These data provide a biological explanation of the different roles played by alloreactive natural killer cells in pediatric versus adult acute lymphoblastic leukemia and suggest that new natural killer-based strategies targeting specific subgroups of patients, particularly those BCR-ABL(+), are worth pursuing further.

    In negotiating stairs, low foot clearance increases the risk of tripping and a fall. Foot clearance may be related to physical fitness, which differs between active and sedentary participants, and be acutely affected by exercise. Impaired stair negotiation could be an acute response to exercise. Here we determined acute changes in foot clearances during stair walking in sedentary (n = 15) and physically active older adults (n = 15) after prolonged exercise. Kinematic data were acquired during negotiation with a 3-steps staircase while participants walked at preferred speed, before and after 30 min walking at preferred speed and using a treadmill. Foot clearances were compared before and after exercise and between the groups. Sedentary older adults presented larger (0.5 cm for lead and 2 cm for trail leg) toe clearances in ascent, smaller (0.7 cm) heel clearance in the leading foot in descent, and larger (1 cm) heel clearance in the trailing foot in descent than physically active. Sedentary older adults negotiate stairs in a slightly different way than active older adults, and 30 min walking at preferred speed does not affect clearance in stair negotiation.

    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.

Developed by an international group of nurse experts and guided by a range of information from research and clinical practice, it focuses on nurse sensitive quality indicators during the acute hospitalisation for fragility hip fracture. Optimal care for the patient who has experienced such a fracture is the focus. This includes (in the first, earlier, part):\\r\

    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.

    In developing countries HAV infection is very common in the first years of life and it is often asymptomatic. However especially in regions of intermediate endemicity, exposure to the virus may delay and outbreaks of hepatitis A may be encountered in adults. The aim of this study is to evaluate the clinical and laboratory findings and risk factors of adults with acute viral hepatitis A. In present study we evaluated 203 patient with acute viral hepatitis A, who were admitted to four different hospitals of three cities of Turkey between January 2000-December 2011, retrospectively. The diagnosis of acute viral hepatitis A was performed by laboratory findings and clinically. In a total of 203 patients, 120 (59.1%) patients were male and 83 (40.9%) were female. Mean age of cases with acute viral hepatitis A was 24.7 +11.8 years (ranged 15 to 82 years old). Acute viral hepatitis A were seen in patient who were 15-20 years and 21-30 years old, commonly. Jaundice (74%), fatigue (68%), nausea- vomiting (56%) and dark urine (48%) were the most common symptoms in cases. Prolonged cholestasis (6.8%) was the most common atypical manifestation. Prolonged jaundice was more frequent in the cases with positive HBsAg (P viral hepatitis A can cause atypical presentations such as prolonged cholestasis, acute kidney injury and fulminant hepatitis. Some precautions such as routine vaccination program, improvement of hygiene conditions and informing people about it, should be taken for reducing of acute viral hepatitis A infection incidence.

    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. PMID:28761199

  16. Review of Acute Traumatic Closed Mallet Finger Injuries in Adults

    2016-03-01

    Full Text Available In adults, mallet finger is a traumatic zone I lesion of the extensor tendon with either tendon rupture or bony avulsion at the base of the distal phalanx. High-energy mechanisms of injury generally occur in young men, whereas lower energy mechanisms are observed in elderly women. The mechanism of injury is an axial load applied to a straight digit tip, which is then followed by passive extreme distal interphalangeal joint (DIPJ hyperextension or hyperflexion. Mallet finger is diagnosed clinically, but an X-ray should always be performed. Tubiana's classification takes into account the size of the bony articular fragment and DIPJ subluxation. We propose to stage subluxated fractures as stage III if the subluxation is reducible with a splint and as stage IV if not. Left untreated, mallet finger becomes chronic and leads to a swan-neck deformity and DIPJ osteoarthritis. The goal of treatment is to restore active DIPJ extension. The results of a six- to eight-week conservative course of treatment with a DIPJ splint in slight hyperextension for tendon lesions or straight for bony avulsions depends on patient compliance. Surgical treatments vary in terms of the approach, the reduction technique, and the means of fixation. The risks involved are stiffness, septic arthritis, and osteoarthritis. Given the lack of consensus regarding indications for treatment, we propose to treat all cases of mallet finger with a dorsal glued splint except for stage IV mallet finger, which we treat with extra-articular pinning.

    Acute alcohol exposure has been shown to produce differential motor impairments between aged and adult rats and between adolescent and adult rats. However, the effects of acute alcohol exposure among adolescent, adult, and aged rats have yet to be systematically investigated within the same project using a dose-dependent analysis. We sought to determine the age- and dose-dependent effects of acute alcohol exposure on gross and coordinated motor performance across the rodent lifespan. Adolescent (PD 30), adult (PD 70), and aged (approximately 18 months) male Sprague-Dawley rats were tested on 3 separate motor tasks: aerial righting reflex (ARR), accelerating rotarod (RR), and loss of righting reflex (LORR). In a separate group of animals, blood ethanol concentrations (BEC) were determined at multiple time points following a 3.0 g/kg ethanol injection. Behavioral tests were conducted with a Latin square repeated-measures design in which all animals received the following doses: 1.0 g/kg or 2.0 g/kg alcohol or saline over 3 separate sessions via intraperitoneal (i.p.) injection. During testing, motor impairments were assessed on the RR 10 min post-injection and on ARR 20 min post-injection. Aged animals spent significantly less time on the RR when administered 1.0 g/kg alcohol compared to adult rats. In addition, motor performance impairments significantly increased with age after 2.0 g/kg alcohol administration. On the ARR test, aged rats were more sensitive to the effects of 1.0 g/kg and 2.0 g/kg alcohol compared to adolescents and adults. Seven days after the last testing session, animals were given 3.0 g/kg alcohol and LORR was examined. During LORR, aged animals slept longer compared to adult and adolescent rats. This effect cannot be explained solely by BEC levels in aged rats. The present study suggests that acute alcohol exposure produces greater motor impairments in older rats when compared to adolescent and adult rats and begins to establish a

    Thirty adult patients suffering from acute nonlymphocytic leukemia (ANLL) were treated according to a modified COAP regimen. Vincristine, cyclophosphamide, and prednisone were given by push injection, while cytosine arabinoside was infused over periods of 8 h. Nineteen patients (63%) achieved complete remission. Remission maintenance therapy consisted of 6-mercaptopurine daily and methotrexate twice weekly. Later in the study, COAP consolidation and reinduction was added, which improved the median duration of complete remission from 7 to 24 months. Comparison of the results with the literature shows that the modified COAP regimen is one of the most effective treatment schedules for adult ANLL.

    There is evidence that an acute bout of exercise confers cognitive benefits, but it is largely unknown what the optimal mode and duration of exercise is and how cognitive performance changes over time after exercise. We compared the cognitive performance of 31 older adults using the Stroop test before, immediately after, and at 30 and 60 min after a 10 and 30 min aerobic or resistance exercise session. Heart rate and feelings of arousal were also measured before, during, and after exercise. We found that, independent of mode or duration of exercise, the participants improved in the Stroop Inhibition task immediately postexercise. We did not find that exercise influenced the performance of the Stroop Color or Stroop Word Interference tasks. Our findings suggest that an acute bout of exercise can improve cognitive performance and, in particular, the more complex executive functioning of older adults.

    We conducted a retrospective chart review to characterize the outcomes of 12 patients-9 men and 3 women, aged 21 to 79 years (mean: 49)-who had been treated at our tertiary care center for acute bacterial meningitis caused by acute otitis media (ABMAO). Fever was the most common presenting sign/symptom, observed in 8 patients, followed by otalgia, neck stiffness, headache, and confusion. An opaque and bulging tympanic membrane was observed in 8 patients. Cultures were positive for Streptococcus pneumoniae in the cerebrospinal fluid, ear, and blood in 7, 5, and 3 patients, respectively. Immediate treatment included tympanocentesis, with aspirates sent for bacteriologic cultures. Seven patients (58.3%) underwent surgery; 5 were operated on early, and 2 underwent surgery at a later stage because of a suspected defect in the mastoid bone. A cortical mastoidectomy was performed in 6 of the 7 surgical patients; the remaining patient underwent a canal-wall-down procedure. Ten patients experienced a full recovery, 1 died, and 1 had a poor neurologic outcome (vegetative state); both of the latter 2 patients were older than 60 years. We conclude that early diagnosis, administration of antibiotics, and myringotomy are crucial for control of ABMAO. A cortical mastoidectomy with ventilation tube insertion can be reserved for patients who do not respond, which is common.

    The role of specific psychiatric diagnoses in emergency department use and/or inpatient hospitalizations (acute care) has not been extensively examined among HIV-infected, unstably housed persons. A community-recruited sample of 284 HIV-infected, unstably housed adults completed the Diagnostic Interview Schedule for DSM-IV. One-third of participants screened positive for major depression and stimulant use disorders. Sleeping on the street [adjusted odds ratio (AOR) = 4.21], major depression (AOR = 2.88) and stimulant use disorders (AOR = 4.45) were associated with greater odds of acute care use. Housing and effective treatment of depression and stimulant use disorders may decrease use of acute care services in this population.

    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.

  6. [Acute intoxication in adults - what you should know].

    Ingestion of household products and plants are the leading cause for calls to the poison control centres as far as children are involved. Severe intoxication in children has become infrequent due to childproofed package and blister packs for drugs. Chemical accidents in adults give rise to hospital admission in only 5 %. Suicidal selfpoisonings are still a challenge for paramedics, emergency and hospital doctors. Natural toxins as amatoxins, cholchicine and snakebites can lead to severe intoxication. Sedatives, antidepressants and analgesics are the drugs which are often used for suicidal intent due to their availability. Quetiapine and paracetamol are the drugs which are ingested for attempted suicide/ suicide mostly. The treatment of poisoning centers on the severity which can be judged by the poison severity score, the Reed classification or the GCS.Most intoxicated patients can be treated symptomatically or by intensive care measurements. Antidotal treatment however is needed for some specific poisonings.Exact sample drawing is essential for diagnostic and forensic purposes. There is no evidence based proof for the effectiveness of primary detoxification from the gastrointestinal tract like forced emesis, gastric lavage or the use of cathartics. Early after the ingestion of a harmful substance the administration of activated charcoal seems advisable. Hemodialysis can remove water soluble substances with a small volume of distribution. Multiple charcoal administration may exhibit some influence on secondary detoxification. Provision of evidence of the efficacy for newer antidotes like hydroxocobalamin in smoke inhalation, fomepizol for toxic alcohols and silibinin for amanita poisoning are emerging. Two recently recommended therapeutic principles have still to demonstrate their ability: Firstly the treatment of patients with calcium receptor antagonistic and beta-receptor antagonistic agents poisoning by high dose of insulin plus glucose, secondly the

    Treatment of acute leukaemia in adult Jehovah's Witnesses (JW) is challenging because of 'a priori' refusal of most physicians to apply diagnostic and therapeutic procedures to haematological abnormalities resembling acute leukaemia. Rejection of blood transfusions by individuals of this faith is usually blamed to justify this attitude, thus leading to severe personal, medical and psychological distress related to the lack of care. We therefore intended to verify whether a standard (tailored) chemotherapy, without the use of prophylactic blood product transfusions, could be applied during treatment of acute leukaemia under such circumstances. Eleven consecutive JW adult patients with acute leukaemia, all of whom had been denied care in other institutions, were treated at the European Institute of Oncology (EIO) in Milan, Italy. Five had acute lymphoblastic leukaemia (ALL) (one bcr/abl positive), six had acute myeloid leukaemia (AML) with immunophenotype and/or cytogenetic intermediate-high risk features, except one patient with acute promyelocytic leukaemia (APML). Standard induction chemotherapy [cytosine arabinoside (ARA-C) and daunorubicin (DNR) for AML, vincristine (VCR), DNR and prednisone (PDN) for ALL, all-trans retinoic acid (ATRA) and DNR for APML] with the antracycline dose of at least 30 mg/sqm were used. All patients experienced severe anaemia after induction chemotherapy despite erythropoietin. Median haemoglobin nadir for patients with ALL and AML was 4.5 g/dL (range 1.3-6.9) and 5.1 g/dL (range 2.6-6.8), respectively. Median platelet nadir counts for all patients was 14.5 x 10(9))/L (range 1-24). One patient died during induction probably due to haemorrhage. Four of five patients with ALL achieved a complete remission (CR) (including the bcr/abl case) while among patients with AML only the one with APML achieved CR. Three patients (APML = 1 and ALL = 2) are still alive and disease-free. This small series of adult patients with leukaemia illustrates

    2014-12-01

    It is a common perception that young people do not become ill and do not pose a challenge in the unscheduled healthcare setting. The research, however, increasingly suggests that young adults and adolescents (YAAs) are a highly vulnerable group, with poorer outcomes than either older adults or children, and distinct healthcare needs. The acute medical unit (AMU) setting poses particular challenges to the care of this patient group. To improve care and patient experience, adult clinicians need to look critically at their services and seek to adapt them to meet the needs of YAAs. This requires cooperation and linkage with local paediatric and emergency services, as well as the input of other relevant stakeholder groups. Staff on AMUs also need to develop the knowledge, skills and attitudes to communicate effectively and address the developmental and health needs of YAAs and their parents/carers at times of high risk and stress.

  9. A systematic review of music therapy practice and outcomes with acute adult psychiatric in-patients.

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

    Full Text Available 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 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. 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. 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. 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.

    Allogeneic hematopoietic cell transplantation has an established role in the treatment of adults with acute lymphoblastic leukemia whose survival when recipients of grafts from adult unrelated donors approaches that of recipients of grafts from sibling donors. Our aim was to determine the role of mismatched unrelated cord blood grafts in transplantation for 802 adults with acute lymphoblastic leukemia in first or second complete remission. Using Cox regression we compared outcomes after 116 mismatched single or double cord blood transplants, 546 peripheral blood progenitor cell transplants and 140 bone marrow transplants. The characteristics of the recipients and their diseases were similar except cord blood recipients were younger, more likely to be non-Caucasians and more likely to have a low white blood cell count at diagnosis. There were differences in donor-recipient human leukocyte antigen-match depending on the source of the graft. Most adult donor transplants were matched at the allele-level considering human leukocyte antigens-A, -B, -C and –DRB1. In contrast, most cord blood transplants were mismatched and considered antigen-level matching; 57% were mismatched at two loci and 29% at one locus whereas only 29% of adult donor transplants were mismatched at one locus and none at two loci. There were no differences in the 3-year probabilities of survival between recipients of cord blood (44%), matched adult donor (44%) and mismatched adult donor (43%) transplants. Cord blood transplants engrafted slower and were associated with less grade 2–4 acute but similar chronic graft-versus-host disease, relapse, and transplant-related mortality. The survival of cord blood graft recipients was similar to that of recipients of matched or mismatched unrelated adult donor grafts and so cord blood should be considered a valid alternative source of stem cells for adults with acute lymphoblastic leukemia in the absence of a matched unrelated adult donor.

    2003-10-01

    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.

    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 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.

    Chromosome banding patterns were obtained for 50 of 55 consecutive adult patients with acute nonlymphocytic leukemia during a 5-yr period. Twenty-two of the 50 cases were diagnosed as acute myelocytic leukemia (AML), 24 as acute myelomonocytic leukemia (AMMol), 2 as acute promyelocytic leukemia (APL), and 2 as erythroleukemia. Twenty-five patients had initial chromosome abnormalities, and five more patients developed abnormalities during the course of the disease. The median survival of patients with normal chromosomes initially (group 1) was 10 mo, whereas that of patients with abnormal chromosomes initially (group II) was 2 mo. Similar times were obtained for treated patients with AML and AMMol. However, when the AML patients were separated into those with and those without a chromosome abnormality, the median survival times were markedly different (2 mo versus 18 mo, respectively). Patients with AMMol demonstrated no difference in median survival times when subgrouped according to the presence or absence of chromosome abnormalities. The treated group II patients whose marrow samples had only abnormal metaphases had a poorer response (10 percent complete remission) and median survival (2 mo) than the group II patients who had at least one normal metaphase (42 percent complete remission with a median survival of 9 mo). The two cases of APL demonstrated a deletion of the long arm of No. 17 which occurred in the same region of the chromosome in each case. Both patients had similar clinical histories, with disseminated intravascular coagulation, and neither responded to therapy.

    To assess chest high-resolution computed tomography (HRCT) findings in patients with acute transformation of adult T cell leukaemia/lymphoma (ATLL). We retrospectively identified 72 consecutive patients at our institution with ATLL between October 2000 and March 2014. The cases included acute type (n = 20), lymphoma type (n = 21), smouldering type (n = 24) and chronic type (n = 7). Sixteen (7 men, 9 women; aged 36-85 years, mean 63.3 years) of 31 patients (24 with smouldering and seven with chronic type; 51.6 %) developed acute transformation of ATLL, and had undergone chest HRCT examinations. Parenchymal abnormalities, enlarged lymph nodes, pericardial effusion, pleural effusion and skin lesions were evaluated on HRCT. Chest HRCT of 15 of the 16 patients showed abnormal findings, including ground-glass opacity (GGO) (n = 8), consolidation (n = 5), interlobular septal thickening (n = 5) and nodules (n = 5). Pleural effusion was found in five patients, lymph node enlargement in 10 patients and multiple skin thickening in two patients. Almost all patients with acute transformation of ATLL had abnormal findings on chest HRCT, which consisted mainly of lymph node enlargement, GGO, interlobular septal thickening, nodules and bilateral pleural effusions.

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.

    The objective was to determine if acute alcohol consumption is associated with differences in injury pattern among young adult patients with traumatic injuries presenting to emergency medical services (EMS). A cross-sectional, retrospective review of prehospital patient care reports (PCRs) was conducted evaluating injured patients who presented to a collegiate EMS agency from January 1, 2011 to December 31, 2012. Included patients were age 18-24 y and sustained an injury within the previous 24 h. PCRs were reviewed independently by two abstractors to determine if the patient was documented to have acutely consumed alcohol proximate to his/her injury. Primary and secondary sites of regional body injury were recorded. Injury severity was recorded using the Revised Trauma Score (RTS). The association between primary injury site and acute alcohol use was assessed using a chi-square test. Multiple logistic regression was used to control for sex in predicting injury type. Of 440 injured patients, 135 (30.6%) had documented alcohol use prior to injury. Acute alcohol consumption altered the overall pattern of regional injury (p Alcohol users were more likely to present with injury secondary to assault, fall/trip, and unknown mechanism of injury (p alcohol group (p alcohol consumption predicted increased risk of head/neck injury 5.59-fold (p alcohol use in collegiate EMS patients appears to alter injury patterns in young adults and increases risk of head/neck injury. EMS providers in similar agencies should consider these trends when assessing and treating injured college-aged patients.

    We have previously demonstrated that aging reduces the compensatory vasodilator response during hypoxic exercise due to blunted nitric oxide (NO) signaling. Recent evidence suggests that NO bioavailability can be augmented by dietary nitrate through the nitrate-nitrite pathway. Thus we tested the hypothesis that acute dietary nitrate supplementation increases the compensatory vasodilator response to hypoxic exercise, particularly in older adults. Thirteen young (25 ± 1 yr) and 12 older (64 ± 2 yr) adults performed rhythmic forearm exercise at 20% of maximum voluntary contraction during normoxia and hypoxia (∼80% O2 saturation); both before (control) and 3 h after beetroot juice (BR) consumption. Forearm vascular conductance (FVC; ml·min(-1)·100 mmHg(-1)) was calculated from forearm blood flow (ml/min) and blood pressure (mmHg). Compensatory vasodilation was defined as the relative increase in FVC due to hypoxic exercise (i.e., % increase compared with respective normoxic exercise trial). Plasma nitrite was determined from venous blood samples obtained before the control trials and each of the exercise trials (normoxia and hypoxia) after BR. Consumption of BR increased plasma nitrite in both young and older adults (P vasodilator response to hypoxic exercise was attenuated in older compared with young adults (3.8 ± 1.7% vs. 14.2 ± 1.2%, P vasodilation did not change in young (13.7 ± 3.3%, P = 0.81) adults but was substantially augmented in older adults (11.4 ± 2.1%, P vasodilator response to hypoxic exercise in older but not young adults.

    Background There has been a marked global increase in the incidence of human Campylobacter enteritis in recent years. This study investigated the epidemiological and clinical features of Campylobacter enteritis in adult patients suffering from acute diarrhea.Methods This was a retrospective review of Campylobacter enteritis in adult patients with acute diarrhea presenting at Beijing University First Hospital, Beijing, China, in the summer and autumn (April to October) of 2005 to 2009. The data collected included the species of campylobacter identified, and the age, gender, clinical manifestations and results of laboratory test on stool samples collected from the patients. Campylobacter sensitivity tests to various antimicrobial agents were conducted on 80 specimens. Chi-square tests were applied using SPSS13.0 software and a two-sided P value of <0.05 was considered statistically significant.Results Campylobacter spp. isolated from the stool specimens of 142 patients with diarrhea represented 14.9% of all the cases examined. C. jejuni was identified in 127 patients (89.4%) and C. coli in 15 others (10.6%). The infection incidence was highest in the age range of 21-30 years which comprised 21.7% of the total cases examined. Most cases of diarrhea (46 patients) occurred in June. Watery diarrhea (97.2%), abdominal pain (72.5%) and fever (64.8%) were the most common manifestations of enteric campylobacteriosis. Only four patients (2.8%) had bloody diarrhea. The antimicrobial resistance rates were: cefoperazone (100%), levofloxacin (61.3%), gentamicin (12.5%), erythromycin (6.3%), and azithromycin (2.5%).Conclusions Campylobacter was prevalent among adults with acute diarrhea from 2005 to 2009 in Beijing, China. The large number of those afflicted by the disease warrants the commission of a large multicenter study to determine the extent of enteric campylobacteriosis in this region.

    AIM: Racecadotril is a specific enkephalinase inhibitor that exhibits intestinal antisecretory activity without affecting intestinal transit. Loperamide is an effective anti-diarrheal agent, but it usually induces constipation. This study is to compare the efficacy, safety, and tolerability of racecadotril versus Ioperamide in the outpatient treatment of acute diarrhea in adults.METHODS: A two-center, randomized, parallel-group,single-blind study was carried out to compare the efficacy,tolerability, and safety of racecadotril (100 mg thrics daily)and Ioperamide (2.0 mg 2 twics daily) in 62 adult patients suffering from acute diarrhea. The main efficacy criterion used was the duration of diarrhea after beginning the treatment (in hours). Other signs and symptoms were also evaluated.RESULTS: The clinical success rates for these antidiarrheal treatments were 95.7% and 92.0% for racecadotril and Ioperamide respectively. Patients on racecadotril had a median duration of diarrhea of 19.5 h compared with a median of 13 h for patients on Ioperamide.Rapid improvement in anal burn and nausea was found for each drug. However, more patients on Ioperamide suffered from reactive constipation (29.0% vs 12.9%).Itching, another adverse event was notably higher in the racecadotril group (28.6% vs 0%). With regard to other adverse events, the two medications showed similar occurrence rates and similar concomitant medication usage rates.CONCLUSION: Racecadotril and Ioperamide are rapid,equally effective treatments for acute diarrhea in adults,but Ioperamide treatment is associated with a higher incidence of treatment-related constipation.

    31 adults suffering from acute leukemia were followed for a period of more than 5 years after achieving complete remission. Maintenance chemotherapy consisted of antimetabolite treatment (mercaptopurine + methotrexate) as well as COAP reinduction every 3 months. Chemotherapy was stopped if the first complete remission lasted for 3 years ("long term remission"). This was the case in 8 out of 31 remission patients (26%). Analysis of hematological parameters at diagnose for long term remission patients revealed that the initial leukocyte count was of prognostic significance.

    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. PMID:27008505

    The survival rate for childhood acute lymphoblastic leukemia (ALL) is greater than 80%. However, many of these survivors develop long-term chronic health conditions, with a relatively common late effect being neurocognitive dysfunction. Although neurocognitive impairments have decreased in frequency and severity as treatment has evolved, there is a subset of survivors in the current treatment era that are especially vulnerable to the neurotoxic effects of ALL and its treatment. Additionally, little is known about long-term brain development as survivors mature into adulthood. A recent study by Zeller et al. compared neurocognitive function and brain volume in 130 adult survivors of childhood ALL to 130 healthy adults matched on age and sex. They identified the caudate as particularly sensitive to the neurotoxic effects of chemotherapy. We discuss the implications and limitations of this study, including how their findings support the concept of individual vulnerability to ALL and its treatment.

    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.

    Full Text Available Objectives: The objective of the present study was to assess locomotor behavior of adult zebrafish after acute exposure to different pharmacological reference compounds. Materials and Methods: Adult zebrafish of 4-5-months-old were exposed to different concentrations of known reference compounds for 15 min. The test was conducted separately for each drug concentration as well as control. Locomotor activity parameters viz. distance travelled, speed, total mobile time, and total immobile time were recorded for each animal during the exposure period. Results: Out of 11 compounds tested, nine compounds showed decrease in locomotor behavior with significant changes in distance travelled, speed, total mobile time, and total immobile time. Caffeine exhibited biphasic response in locomotion behavior, while scopolamine failed to induce any significant changes. Conclusion: In view of the above findings, these results suggested that exposure of adult zebrafish with different known compounds produce the expected changes in the locomotion behavior; therefore, adult zebrafish can be used an alternative approach for the assessment of new chemical entities for their effect on locomotor behavior.

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.

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.

    Sapovirus has been accepted as a major cause of acute gastroenteritis worldwide. It can affect all age groups, ranging from young adults to the elderly, while little is known about the epidemiological patterns and genetic characteristics of sapovirus infections in China. To investigate the prevalence of sapovirus infections among adult outpatients suffering from acute gastroenteritis in Shanghai, China. From April 2011 to March 2013, fecal specimens from 1125 adult outpatients (≥16 years of age) with acute gastroenteritis were collected. Reverse transcription polymerase chain reaction (RT-PCR) was employed for detection of sapovirus, and 5' end of capsid gene were sequenced for genotyping and phylogenetic analysis. The overall occurrence of sapovirus infection in adult outpatients was 3.73% (42 in 1125) through the two-year surveillance period, and sapovirus diarrhea is more common in spring and winter. The highest sapovirus positive rate was observed in adults of ≥56 years old, and statistically significant relationship was observed when compared with other age groups (pSapovirus was commonly found in adults with acute gastroenteritis in Shanghai, China, while no specific seasonal variation of sapovirus diarrhea could be distinguished.

    Full Text Available Acute post-infectious glomerulonephritis (APIGN is uncommonly seen in adults; its incidence is progressively declining, particularly in developed countries. The aim of this study was to evaluate the epidemiological, clinical and biologic features of APIGN in a Tunisian center. A retrospective descriptive analytic study was carried out on 50 patients aged more than 15 years who were admitted to the Monastir Hospital between 1991 and 2007, with a diagnosis of APIGN. There were more males than females (66% vs. 34%, and the mean age of the patients was 36.8 ± 10 years. Only 10% had an immunocompromised background, including diabetes. The most common site of infection was upper respiratory tract, followed by skin and pneumonia. The most common causative agent was Streptococcus (66%, followed by Staphylococcus (12%. 73.8% of the patients had low C3 complement levels. The mean peak serum creatinine was 190 μmol, and 4% of patients required acute dialysis. The patients were followed-up for a mean period of 18 months (range, 0.16-97 months. During follow-up, of the 46 patients reviewed in the consultation, the majority showed complete remission, 12 patients had persisting abnormalities such as hypertension in 17%, chronic renal failure in 8% and proteinuria in 6.5%, and one patient had concomitant hypertension and chronic renal failure. Our study suggests that APIGN is still endemic in some parts of the world such as Tunisia, and our data showed a favorable prognosis in adults.

In contrast to COPD patients, altered electrolyte transport and malnutrition in CF patients may predispose them to metabolic alkalosis and, therefore, may contribute to hypercapnia. The aim of this study was to determine the prevalence of metabolic alkalosis in adults with hypercapnic respiratory failure in the setting of acute exacerbations of CF compared with COPD. Levels of arterial blood gases, plasma electrolytes, and serum albumin from 14 consecutive hypercapnic CF patients who had been admitted to the hospital with a respiratory exacerbation were compared with 49 consecutive hypercapnic patients with exacerbations of COPD. Hypercapnia was defined as a PaCO(2) of > or = 45 mm Hg. Despite similar PaCO(2) values, patients in the CF group were significantly more alkalotic than were those in the COPD group (mean [+/- SD] pH, 7.43 +/- 0.03 vs 7.37 +/- 0.05, respectively; p respiratory acidosis and metabolic alkalosis was evident in 71% of CF patients and 22% of COPD patients (p alkalosis contributes to hypercapnic respiratory failure in adults with acute exacerbations of CF. This acid-base disturbance occurs in conjunction with reduced total body salt levels and hypoalbuminemia.

    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

    Full Text Available Dengue is an emerging infectious disease of global significance. 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.

    Aim This study investigated the prevalence of sapovirus infections in patient with acute gastroenteritis in Tehran, Iran. Background Sapovirus, a member of the family Caliciviridae is one of the major causative agents of viral gastroenteritis affecting both children and adult individuals. There isn't enough data about prevalence and genotypes of sapovirus infection in Tehran, the capital city of Iran. Patients and methods A total of 42 fecal samples were collected from patients with acute gastroenteritis from May to July 2009. RT nested- PCR was performed for screening. To genotype the sapovirus isolates, some positive samples were subjected to phylogenetic analysis by sequencing of fragments of viral capsid gene region. Results Sapovirus was detected in 5 of 42 stool specimens from patients with acute gastroenteritis. Sapovirus detected in this study was clustered into only one distinct genogroup I/2. Sapovirus GI/2 was predominant. Conclusion Our results show that among the studied viruses responsible for this disease, sapovirus was a major viral isolate virus. PMID:24834197

    Full Text Available Abstract Background Bilateral simultaneous angle closure glaucoma is a rare entity. To our knowledge this is the first reported case of bilateral acute angle-closure glaucoma secondary to isolated microspherophakia in an adult. Case presentation A 45-year-old woman presented with bilateral acute angle closure glaucoma, with a patent iridotomy in one eye. Prolonged miotic use prior to presentation had worsened the pupillary block. The diagnosis was not initially suspected, and the patient was subjected to pars-plana lensectomy and anterior vitrectomy for a presumed ciliary block glaucoma. The small spherical lens was detected intraoperatively, and spherophakia was diagnosed in retrospect. She had no systemic features of any of the known conditions associated with spherophakia. Pars-plana lensectomy both eyes controlled the intraocular pressure successfully. Conclusion This case demonstrates the importance of considering the diagnosis of isolated microspherophakia in any case of bilateral acute angle closure glaucoma. Lensectomy appears to be an effective first-line strategy for managing these patients.

    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.

    Full Text Available In 264 adult acute diarrhea cases with moderate course it was analyzed both symptoms and agents detected by different methods: in 91 cases (examined in the period of shigellosis high incidence level — by culture and serologic (specific antibodies detection methods to detect Shigella spp. and Salmonella spp. plus ELISA method to detect rotavirus antigen in feces; in 173 cases (examined in the period of shigellosis low incidence level — by above mentioned methods plus PCR based method. 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. PCR-based diagnostic method additionally used (in the period of shigellosis low incidence level resulted in detection of Campylobacter spp. accounted for campilobacteriosis as mono infection in 20,8% cases and as mixed infection (in association with other enteropatho-gens — in 4% cases. In cases with colitis the additional usage of PCR-based diagnostic method resulted in Salmonella spp. and Campylobacter spp. detection in every third case, Shigella spp. and agent association detection — in every fifth case. The target analysis of enteropathogens detected in 15 cases positive for rotavirus (examined in the period of shigellosis low incidence level has shown that in 6 of them there has been detected association of rotavirus with other agents predominantly bacterial ones (in 5 of 6 cases. 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.

    Full Text Available Activin A is known as a neuroprotective factor produced upon acute excitotoxic injury of the hippocampus (in pathological states. We attempt to reveal the role of activin as a neuromodulator in the adult male hippocampus under physiological conditions (in healthy states, which remains largely unknown. We showed endogenous/basal expression of activin in the hippocampal neurons. Localization of activin receptors in dendritic spines (= postsynapses was demonstrated by immunoelectron microscopy. The incubation of hippocampal acute slices with activin A (10 ng/mL, 0.4 nM for 2 h altered the density and morphology of spines in CA1 pyramidal neurons. The total spine density increased by 1.2-fold upon activin treatments. Activin selectively increased the density of large-head spines, without affecting middle-head and small-head spines. Blocking of Erk/MAPK, PKA or PKC prevented the activin-induced spinogenesis by reducing the density of large-head spines, independent of Smad-induced gene transcription which usually takes more than several hours. Incubation of acute slices with activin for 2 h induced the moderate early long-term potentiation (moderate LTP upon weak theta burst stimuli. This moderate LTP induction was blocked by follistatin, MAPK inhibitor (PD98059 and inhibitor of NR2B subunit of NMDA receptors (Ro25-6981. It should be noted that the weak theta burst stimuli alone cannot induce moderate LTP. These results suggest that MAPK-induced phosphorylation of NMDA receptors (including NR2B may play an important role for activin-induced moderate LTP. Taken together, the current results reveal interesting physiological roles of endogenous activin as a synaptic modulator in the adult hippocampus.

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

    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 epiglottitis is a potentially life threatening disease, with a growing incidence in the adult population. Its long-term outcome after Intensive Care Unit (ICU hospitalization has rarely been studied.Thirty-four adult patients admitted for acute epiglottitis were included in this retrospective multicentric study. The mean age was 44 ± 12 years (sex ratio: 5.8. Sixteen patients (47% had a history of smoking while 8 (24% had no previous medical history. The average time of disease progression before ICU was 2.6 ± 3.6 days. The main reasons for hospitalization were continuous monitoring (17 cases, 50% and acute respiratory distress (10 cases, 29%. Microbiological documentation could be made in 9 cases (26%, with Streptococcus spp. present in 7 cases (21%. Organ failure at ICU admission occurred in 8 cases (24%. Thirteen patients (38% required respiratory assistance during ICU stay; 9 (26% required surgery. Two patients (6% died following hypoxemic cardiac arrest. Five patients (15% had sequelae at 1 year. Patients requiring respiratory assistance had a longer duration of symptoms and more frequent anti inflammatory use before ICU admission and sequelae at 1 year (p < 0.05 versus non-ventilated patients. After logistic regression analysis, only exposure to anti-inflammatory drugs before admission was independently associated with airway intervention (OR, 4.96; 95% CI, 1.06-23.16.The profile of the cases consisted of young smoking men with little comorbidity. Streptococcus spp. infection represented the main etiology. Outcome was favorable if early respiratory tract protection could be performed in good conditions. Morbidity and sequelae were greater in patients requiring airway intervention.

    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

    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.

    To determine whether experimentally induced acute moderate hyperglycemia is associated with coagulation activation in healthy adult horses. Prospective experimental study. University veterinary teaching hospital. Six healthy adult horses. Hyperglycemia (10.0-13.3 mmol/L [180-240 mg/dL]) was induced and maintained for 6 hours using a hyperglycemic clamp technique. Blood glucose concentrations were assessed using a point of care (POC) glucometer at 10- and 20-minute intervals throughout the hyperglycemic clamp procedure. Platelet count, fibrinogen concentration, prothrombin time (PT), activated partial thromboplastin time (aPTT), thrombin antithrombin complex level (TAT), and thromboelastometry (TEM) were determined before and after jugular catheter placement, prior to glucose administration, and at 3 and 6 hours of sustained hyperglycemia. Data were analyzed by repeated measures analysis of variance with significance defined as P 10.0 mmol/L (>180 mg/dL) throughout the duration of the hyperglycemic clamp with a mean concentration of 11.9 ± 0.3 mmol/L [216 ± 6 mg/dL] as measured by the POC glucometer. No significant difference was found for any evaluated parameter associated with sustained hyperglycemia. Intravenous catheter placement resulted in a significant increase in mean TAT (0.8 ± 0.3 μg/L pre-catheter, 2.3 ± 0.8 μg/L post-catheter; P = 0.008). Acute, moderate hyperglycemia in healthy adult horses does not have a detectable effect on coagulation based on evaluated parameters. Jugular catheter placement results in a transient increase in thrombin generation as determined by increased TAT concentrations. © Veterinary Emergency and Critical Care Society 2012.

    Backround: Surgical treatment of appendicitis remains the standard treatment, but many cases respond conservatively. Our purpose was the clarification of the clinical, laboratory and imaging characteristics of uncomplicated cases undergoing successful conservative treatment without recurrence. Methods: 105 adult patients (66 female, 39 male) with non-complicated acute appendicitis. Symptom duration, clinical abdominal examination, body temperature, inflammatory markers, imaging studies results and in-hospital treatment were recorded. No patient had a previous episode of appendicitis. Results: Duration of symptoms was 2 hours-3 days. Abdominal examination was compatible with appendicitis and findings were localized in the lower right quadrat. The majority (85.7%) had no or low fever ( 37.4 C). All had leukocytosis (range: 10.000-22.900 WBC/L, mean 14.370'+-2.900 WBC/L), 3 patients 20.000 WBC/L. All had CRP 3.36 mg/L (mean 46.8'+-40.5 mg/L), and 3 150 mg/L. U/S was performed on 95 patients (combined with transvaginal U/S in 19 females) with positive findings of acute appendicitis in 91 (91/95, 95.7%). When faced with inconclusive findings, CT was performed (13 patients) and MRI on one pregnant. In-hospital conservative treatment lasted 1-10 days, overstay was 1-2 days following clinic-laboratory regression. Outpatient, antibiotic treatment followed discharge in 27 patients. Conclusions: Young patients with non-complicated acute appendicitis and short symptom duration, without rare etiologic pathologies, are candidates for conservative treatment. Diagnosis of non-complicated acute appendicitis is based on combining clinical signs, positive inflammatory markers and imaging studies, excluding complicated cases, generalized peritonitis and sepsis. The inflammation seems self-limited, while the role of anti-inflammatory drugs remains obscure.

    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.

    The prognostic value of cytogenetics in adult acute lymphoblastic leukemia (ALL) is not as established as in childhood ALL. We have analyzed the outcome and prognostic value of karyotype in 84 adults diagnosed with Philadelphia-negative ALL from a single institution that received induction chemotherapy and had successful karyotype performed. The most frequent finding was normal karyotype in 35 (42%) cases, followed by aneuploidies in 20 cases (24%) and t(4;11)(q21;q23)/MLL/AF4 in 5 (6%), and the remaining 24(27%) cases carried miscellaneous clonal abnormalities. The group of patients with t(4;11)(q21;q23)/MLL/AF4, hypodiploidy and low hyperdiploidy (less than 50 chromosomes) showed a worse outcome than those with normal karyotype and miscellaneous abnormalities in terms of overall survival (OS) (3 years OS; 47% vs. 13%, p = 0.014) and relapse-free survival (RFS) (3 years RFS; 44% vs. 27%, p = 0.005). Other cytogenetic prognostic classifications reported to date were tested in our series, but any was fully reproducible. In conclusion, karyotype is a useful tool for risk assessment in adult ALL. We have confirmed the bad prognosis of t(4;11)(q21;q23)/MLL/AF4 and hypodiploidy. Besides, low hyperdiploidy could also define a high-risk group of patients who might be candidates for more intensive treatment.

    Objective: To construct tissue-engineered neural complex in vitro and study its effect in repairing acutely injured spinal cord in adult rats. Methods: Neural stem cells were harvested from the spinal cord of embryo rats and propagated in vitro. Then the neural stem cells were seeded into polyglycolic acid scaffolds and co-cultured with extract of embryonic spinal cord in vitro. Immunofluorescence histochemistry and scanning electron microscope were used to observe the microstructure of this complex. Animal model of spine semi-transection was made and tissue-engineered neural complex was implanted by surgical intervention. Six weeks after transplantation, functional evaluation and histochemistry were applied to evaluate the functional recovery and anatomic reconstruction. Results: The tissue-engineered neural complex had a distinct structure, which contained neonatal neurons, oligodendrocytes and astrocytes. After tissue-engineered neural complex was implanted into the injured spinal cord, the cell components such as neurons, astrocytes and oligodendrocytes, could survive and keep on developing. The adult rats suffering from spinal cord injury got an obvious neurological recovery in motor skills. Conclusions: The tissue-engineered neural complex appears to have therapeutic effects on the functional recovery and anatomic reconstruction of the adult rats with spinal cord injury.

  1. The Study on BCR/ABL Fusion Gene in Adult Acute Lymphoblastic Leukemia

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    In order to assess the significance of BCR/ABC fusion gene in adult acute lymphoblastic Leukemia (ALL), 28 patients who were diagnosed as ALL were enrolled to detect BCR/ABC gene using nested-RT PCR. The results showed that 9 cases (31.25%) were BCR/ABL positive ,and expressed P210 subtype. A mong them 7 cases were B-ALL, and one was T-ALL. The diagnosis was proved by monoclonal antibodies recognition by indirect immunofluorescence. Adult patients with BCR/ABL positive ALL were significantly older (p<0. 01) and had higher WBC count (p<0. 01) as compared with BCR/ABL-negative patients. There was no significant difference in sex, hemoglobin and splenomegaly between two group (p>0. 05). The induc tion failure rate was high in BCR/ABL positive patients and those who achieved complete remission usually relapsed earlier. In conclusion, adult ALL patients with BCR/ABL-positive have poorer prognosis.

    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.

    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 (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 Malaria was confirmed by PCR in four (1.7%) of the 241 febrile patients. AHI was as common as confirmed malaria in 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.

    Background Therapeutic protocols used in adult acute lymphoblastic leukemia (ALL) are widely variable, and glucocorticoids (GCs) are essential components in ALL treatment. Therefore, this study aimed to evaluate the distribution of prominent glucocorticoid receptor (GR) gene polymorphic variants among adult ALL patients. We also investigated the association between GR messenger ribonucleic acid (mRNA) isoform expressions and the response to chemotherapy. Methods Fifty-two newly diagnosed Philadelphia-negative adult ALL patients and 30 healthy control subjects were enrolled in this study. Genotyping was carried out using a polymerase chain reaction (PCR)-restriction fragment length polymorphism analysis. GR mRNA isoform expressions were assayed by quantitative real-time PCR. Results ALL patients in this study had a median age of 34 years (range, 18-75). GRα expression was associated with complete remission (P=0.03), while GRγ mRNA expression was significantly higher in GC resistant patients (P=0.032) and in non-responders (P=0.019). However, there were no significant associations with GC resistance. The BclI polymorphic variant of the GR gene was the most frequent in adult ALL patients and was not associated with the GC response. Both higher GRα expression and lower GRγ expression were associated with achievement of complete remission, while higher GRγ expression was associated with GC-resistance. Conclusion Our data suggest that the level of GR isoform expression may be useful in predicting GC response, achievement of complete remission, and better event-free survival in ALL patients. However, further evaluation with a larger cohort of patients is warranted. PMID:26770951

    Background: Acute abdominal pain is a common symptom of emergency patients. The severity was always evaluated based on physicians’ clinical experience. The aim of this study was to establish an early risk stratification method (ERSM) for addressing adults with acute abdominal pain, which would guide physicians to take appropriate and timely measures following the established health-care policies. Methods: In Cohort 1, the records of 490 patients with acute abdominal pain that developed within the past 72 h were enrolled in this study. Measurement data and numeration data were compared with analysis of variance and Chi-square test, respectively. Multiple regression analysis calculated odd ratio (OR) value. P and OR values showed the impacts of factors. ERSM was established by clinical experts and statistical experts according to Youden index. In Cohort 2, data from 305 patients with acute abdominal pain were enrolled to validate the accuracy of the ERSM. Then, ERSM was prospectively used in clinical practice. Results: The ERSM was established based on the scores of the patient's clinical characteristics: right lower abdominal pain + 3 × diffuse abdominal pain + 3 × cutting abdominal pain + 3 × pain frequency + 3 × pain duration + fever + 2 × vomiting + 5 × stop defecation + 3 × history of abdominal surgery + hypertension history + diabetes history + hyperlipidemia history + pulse + 2 × skin yellowing + 2 × sclera yellowing + 2 × double lung rale + 10 × unconsciousness + 2 × right lower abdominal tenderness + 5 × diffuse abdominal tenderness + 4 × peritoneal irritation + 4 × bowel sounds abnormal + 10 × suspicious diagnosis + white blood cell count + hematocrit + glucose + 2 × blood urea nitrogen + 3 × creatine + 4 × serum albumin + alanine aminotransferase + total bilirubin + 3 × conjugated bilirubin + amylase. When the score was <18, the patient did not need hospitalization. A score of ≥18 and <38 indicated that the patient should be under

    Adult onset Still's disease (AOSD) is a systemic inflammatory disorder characterized by rash, leukocytosis, fever and arthralgia/arthritis. The most common pulmonary manifestations associated with AOSD are pulmonary infiltrates and pleural effusion. The present study describes a 40-year-old male with AOSD who developed fever, sore throat and shortness of breath. Difficulty breathing promptly developed, and the patient was diagnosed with acute respiratory distress syndrome (ARDS). The patient did not respond to antibiotics, including imipenem, vancomycin, fluconazole, moxifloxacin, penicillin, doxycycline and meropenem, but was sensitive to glucocorticoid treatment, including methylprednisolone sodium succinate. ARDS accompanied by AOSD has been rarely reported in the literature. In conclusion, in a patient with ARDS who does not respond to antibiotic treatment, the involvement of AOSD should be considered.

    Cancer progresses with a change in the structure of the gene network in normal cells. We define a measure of organizational hierarchy in gene networks of affected cells in adult acute myeloid leukemia (AML) patients. With a retrospective cohort analysis based on the gene expression profiles of 116 AML patients, we find that the likelihood of future cancer relapse and the level of clinical risk are directly correlated with the level of organization in the cancer related gene network. We also explore the variation of the level of organization in the gene network with cancer progression. We find that this variation is non-monotonic, which implies the fitness landscape in the evolution of AML cancer cells is non-trivial. We further find that the hierarchy in gene expression at the time of diagnosis may be a useful biomarker in AML prognosis.

    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.

    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.

    The transition from wakefulness to sleep is associated with a pronounced decline in diuresis, a necessary physiological process that allows uninterrupted sleep. The aim of this study was to assess the effect of acute sleep deprivation (SD) on urine output and renal water, sodium, and solute handling in healthy young volunteers. Twenty young adults (10 male) were recruited for two 24-h studies under standardized dietary conditions. During one of the two admissions, subjects were deprived of sleep. Urine output, electrolyte excretions, and osmolar excretions were calculated. Activated renin, angiotensin II, aldosterone, arginine vasopressin, and atrial natriuretic peptide were measured in plasma, whereas prostaglandin E(2) and melatonin were measured in urine. SD markedly increased the diuresis and led to excess renal sodium excretion. The effect was more pronounced in men who shared significantly higher diuresis levels during SD compared with women. Renal water handling and arginine vasopressin levels remained unaltered during SD, but the circadian rhythm of the hormones of the renin-angiotensin-aldosterone system was significantly affected. Urinary melatonin and prostaglandin E(2) excretion levels were comparable between SD and baseline night. Hemodynamic changes were characterized by the attenuation of nocturnal blood pressure dipping and an increase in creatinine clearance. Acute deprivation of sleep induces natriuresis and osmotic diuresis, leading to excess nocturnal urine production, especially in men. Hemodynamic changes during SD may, through renal and hormonal processes, be responsible for these observations. Sleep architecture disturbances should be considered in clinical settings with nocturnal polyuria such as enuresis in children and nocturia in adults.

    The pathogenesis of acute myeloid leukemia (AML) involves the cooperation of mutations promoting proliferation/survival and those impairing differentiation. Point mutations of the N-RAS gene are the most frequent somatic mutations causing aberrant signal-transduction in acute myeloid leukemia (AML). The aim of the present work is to study the frequency and prognostic significance of N-RAS gene mutations (N-RASmut) in de novo Egyptian adult AML. Bone marrow specimens from 150 patients with de novo acute myeloid leukemia and controls were analyzed by genomic PCR-SSCP at codons 12, 13 (exon 1), and 61 (exon 2) for N-RAS mutations. In 12.7% (19/150) AML cases, N-RAS gene mutations were found and were observed more frequently in the FAB subtype M4eo (P = 0.028) and with codon 12, 13 (14 of 19; 73.7%). Patients with N-RAS mutation had a significant lower peripheral and marrow blasts (P = 0.004, P = 0.03) and clinical outcome did not improve more than in patients without mutation. In patients with N-RAS gene mutation vs. those without, complete remission rate was (63.2% vs. 56.5%; P = 0.46), resistant disease (15.8% vs. 23.6%; P = 0.51), three years overall survival (44% vs 42%; P= 0.85) and disease free survival (42.1% vs. 38.9%, P = 0.74). Multivariate analysis showed that age was the strongest unfavorable factor for overall survival (relative risk [RR], 1.9; P = 0.002), followed by cytogenetics (P = 0.004). FAB types, N-RAS mutation and leukocytosis were the least important. In conclusion, the frequency and spectrum of N-RAS gene mutation differ between biologically distinct subtypes of AML but do not significantly influence prognosis and clinical outcome in patients with AML.

    Full Text Available The acute effect of whole-body vibration (WBV training may enhance muscular performance via neural potentiation of the stretch reflex. The purpose of this study was to investigate if acute WBV exposure affects the stretch induced knee jerk reflex [onset latency and electromechanical delay (EMD] and the isokinetic knee extensor peak torque performance. Twenty-two subjects were randomly assigned to the intervention or control group. The intervention group received WBV in a semi-squat position at 30° knee flexion with an amplitude of 0.69 mm, frequency of 45 Hz, and peak acceleration of 27.6 m/s2 for 3 minutes. The control group underwent the same semii-squatting position statically without exposure of WBV. Two-way mixed repeated measures analysis of variance revealed no significant group effects differences on reflex latency of rectus femoris (RF and vastus lateralis (VL; p = 0.934 and 0.935, respectively EMD of RF and VL (p = 0.474 and 0.551, respectively and peak torque production (p = 0.483 measured before and after the WBV. The results of this study indicate that a single session of WBV exposure has no potentiation effect on the stretch induced reflex and peak torque performance in healthy young adults.

    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.

    The aim of this study is to report ophthalmic findings of acute mercury poisoning in 48 adults referred to emergency department. Full ophthalmologic examination including the best corrected visual acuity, external eye examination, reaction to light, a slit-lamp examination, funduscopy, intraocular pressure measurements, and visual field (VF) and color vision (CV) tests were performed at the presentation and repeated after 6 months. The parametric values of VF test, the mean deviation (MD), and pattern standard deviation (PSD) were recorded in order to compare patients and the 30 healthy controls. The mean parameter of color confusion index in patients was found to be statistically different than controls (p < 0.01). The MD and PSD in patients were different from controls statistically significant (p < 0.01 and p < 0.01, respectively). There was no correlation between the ocular findings and the urine and blood mercury levels. Methyl mercury, held in the school laboratory for experimental purpose, may be a source of poisoning. In this case series, we showed that acute exposure to mercury had hazardous effect on the visual system, especially CV and VF. We propose that emphasizing the public education on the potential hazards of mercury is crucial for preventive community health.

    Using a serological test, different criteria have been established for classifying a case as primary or secondary dengue virus infection. Considering the dengue epidemiological situation in Cuba, IgG antibody response to dengue virus infection in serum samples from children and adults with a dengue 3 infection, in Havana city during the 2001-2002 epidemic was evaluated. Samples were collected on days 5-7 of fever onset and tested by an ELISA inhibition. A total of 713 serum samples positive for IgM antibody, 93 from children and 620 from adult patients were studied. Serum samples collected from healthy blood donors and patients not infected with dengue were included as controls. An IgG primary infection pattern was observed in sera collected from children, with titers of or =1280 (83.9%), respectively. These results permitted the definition of a primary or secondary case of dengue virus infection in serum samples collected during the acute phase of dengue virus infection.

    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.

    Recent studies indicate that survivors of childhood acute lymphoblastic leukemia (ALL) are at increased risk of obesity and cardiovascular disease, conditions that healthy dietary patterns may help ameliorate or prevent. To evaluate the usual dietary intake of adult survivors of childhood ALL, food frequency questionnaire data were collected from 72 participants, and compared with the 2007 World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) Cancer Prevention recommendations, the Dietary Approaches to Stop Hypertension (DASH) diet, and the 2005 United States Department of Agriculture (USDA) Food Guide. Mean daily energy intake was consistent with estimated requirements; however, mean body mass index was 27.1 kg/m2 (overweight). Dietary index scores averaged fewer than half the possible number of points on all 3 scales, indicating poor adherence to recommended guidelines. No study participant reported complete adherence to any set of guidelines. Although half the participants met minimal daily goals for 5 servings of fruits and vegetables (WCRF/AICR recommendations) and Food Guide), participants reported dietary sodium and added sugar intake considerably in excess of recommendations, and suboptimal consumption of whole grains. Guideline adherence was not associated with either body mass index or waist circumference, perhaps due to the low dietary index scores. These findings suggest that dietary intake for many adult survivors of childhood ALL is not concordant with dietary recommendations that may help reduce their risk of obesity, cardiovascular disease, or other treatment-related late effects.

    To determine the effectiveness of the psychotherapeutic strategies designed to improve the outcomes in adults with schizophrenia in both, acute and stable phase of disease. 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.

    In healthy adults, voluntary inhibition of micturition is associated with an increasing sensation in the urge to void and pain, and acute pain has been associated with transient deterioration in aspects of cognitive function. Eight healthy young adults consumed 250 ml of water every 15 min until they could no longer inhibit voiding. Performance on standardized measures of cognitive function was measured at hourly intervals which were classified as baseline, when individuals reported an increase in the urge to void, a strong increase in the urge to void, an extreme increase in the urge to void and postmicturition. Sensations of the urge to void and pain increased with time of inhibition of urge to void and with amount of water consumed. Having an extreme urge to void exerted a large negative effect on attentional and working memory functions (d>0.8). These cognitive functions returned to normal levels after micturition. The magnitude of decline in cognitive function associated with an extreme urge to void was as large and equivalent or greater than the cognitive deterioration observed for conditions known to be associated with increased accident risk.

    2009-01-01

    Acute respiratory distress syndrome (ARDS) remains a poor prognosis in spite of the recent development of new therapeutic strategies. Cell-based therapy with stem cells has been considered as a promising way for the treatment of vital organ damage. Putative endogenous stem cells have been shown to be located within the adult lung in the basal layer of the upper airways, within or near pulmonary neu-roendocrine cell rests, at the bronchoalveolar junction, as well as within the alveolar epithelium. These stem cells are hypothesized to be the source of lung regeneration and repair. But this mechanism seems to be insufficient after lung injury. There is increasing excitement over the last few years with the suggestion that exogenous stem cells may offer new treatment options for ARDS. Exogenous stem cells have the abihty to differentiate and function as both airway and lung parenchymal epithelial cells in both in vitro and in-creasingly in vivo experiments. However, there is great con-troversy concerning the repair effect of adult stem cells in lung injury. This review evaluates the advances in endog-enous respiratory stem cells, and assesses the evidence for the use of stem cells in the repair of lung injury.

There was not enough evidence about the efficacy of occupational therapy, but considering patients preferences and its wide clinical utilization, the GDG suggested its inclusion. Psychoeducation, family intervention and social skill training are recommended to be offered for the treatment of schizophrenia.

    Adult survivors of childhood acute lymphoblastic leukemia (ALL) are at increased cardiovascular risk. Studies of factors including treatment exposures that may modify risk of low cardiorespiratory fitness in this population have been limited. To assess cardiorespiratory fitness, maximal oxygen uptake (VO2 max) was measured in 115 ALL survivors (median age, 23.5 years; range 18-37). We compared VO2 max measurements for ALL survivors to those estimated from submaximal testing in a frequency-matched (age, gender, race/ethnicity) 2003-2004 National Health and Nutritional Examination Survey (NHANES) cohort. Multivariable linear regression models were constructed to evaluate the association between therapeutic exposures and outcomes of interest. Compared to NHANES participants, ALL survivors had a substantially lower VO2 max (mean 30.7 vs. 39.9 ml/kg/min; adjusted P VO2 max than NHANES participants. For key treatment exposure groups (cranial radiotherapy [CRT], anthracycline chemotherapy, or neither), ALL survivors had substantially lower VO2 max compared with NHANES participants (all comparisons, P VO2 max. Among females, CRT was associated with low VO2 max (P = 0.02), but anthracycline exposure was not (P = 0.58). In contrast, among males, anthracycline exposure ≥ 100 mg/m(2) was associated with low VO2 max (P = 0.03), but CRT was not (P = 0.54). Adult survivors of childhood ALL have substantially lower levels of cardiorespiratory fitness compared with a similarly aged non-cancer population. Copyright © 2013 Wiley Periodicals, Inc.

    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.

    Acute bronchitis is a predominantly viral illness and, according to clinical practice guidelines, should not be treated with antibiotics. Despite clear guidelines, acute bronchitis continues to be the most common acute respiratory illness for which antibiotics are incorrectly prescribed. Although the national benchmark for antibiotic prescribing for adults with acute bronchitis is 0%, a preliminary record review before implementing the intervention at the project setting showed that 96% (N = 30) of adults with acute bronchitis in this setting were prescribed an antibiotic. This quality improvement project utilized a single-group, pre-post design. The setting for this project was a large urgent care network with numerous locations in central North Carolina. The purpose was to determine whether nurse practitioners and physician assistants, after participating in a multifaceted provider education session, would reduce inappropriate antibiotic prescribing for healthy adults with acute uncomplicated bronchitis. Twenty providers attended 1 of 4 training sessions offered in October and November 2015. The face-to-face interactive training sessions focused on factors associated with inappropriate antibiotic prescribing, current clinical practice guidelines, and patient communication skills. Retrospective medical record review of 217 pretraining and 335 posttraining encounters for acute bronchitis by 19 eligible participating providers demonstrated a 61.9% reduction in immediate antibiotic prescribing from 91.7% to 29.8%. Delayed prescribing, which accounted for a small percentage of the total prescriptions given, had a small but significant increase of 9.3% after training. Overall, this multifaceted, interactive provider training resulted in significant reductions in inappropriate prescriptions.

    Full Text Available Retropharyngeal abscesses (RPA are rare in adults. We report a case of a healthy adult with RPA presenting with clinical symptoms of acute thyroiditis. A 37-yr-old female presented with a painful mass in the anterior region of the neck, sore throat, mild fever and dysphagy for liquids and solids. Neck emergency US disclosed normal thyroid ventrally displaced by a huge retropharyngeal hypoechoic mass. Direct laryngoscopy revealed erythema of the posterior pharyngeal wall with bulges (8 cm preventing the correct visualization of the glottic plane. CT confirmed the presence of retropharyngeal abscess and laryngoscopic drainage was performed. The patient was discharged on 11th post-operative day, in good condition. The high mortality rate of retropharyngeal abscess is related to its association with invasion of contiguous structures and mediastinum: once mediastinitis occurs, mortality reaches 50%, even with antibiotic therapy. CT is fundamental for the diagnosis, but in many cases, as our, ultrasonography of the neck may play a pivotal role as quickly as possible. Surgical treatment (intraoral incision and drainage is the better definitive and resolutive treatment. The clinical diagnosis of retropharyngeal abscess in adult can be difficult because of the lacking and non specificity of clinical presentation. It is recommended to collect accurate clinical history, careful examination of the head and neck and use of early ultrasound examination of the neck, which in real time can give precise indications to guide the diagnosis and therapy. The management of a retropharyngeal abscess depends on the patient’s clinical condition, moving from conservative treatment with steroids and antibiotics to reanimation and aggressive surgical drainage.

    Acute myeloid leukemia (AML) rarely involves the central nervous system (CNS). Little is known about the clinical course in adult AML patients since most studies examined pediatric patients. Therefore, this study analyzed the data of patients treated in three prospective trials of the "Study Alliance Leukemia" (SAL) study group for CNS involvement. In all, 3,261 AML patients included in the prospective AML96, AML2003, and AML60+ trials of the SAL study group were analyzed. Symptomatic patients underwent cerebrospinal fluid (CSF) puncture and CNS involvement was diagnosed depending on morphology and/or flow cytometry of the CSF. Cytogenetic, molecular, clinical, and laboratory parameters were analyzed in order to identify risk factors. A total of 55 patients had proven symptomatic CNS involvement. Significantly more patients revealed CNS involvement at relapse (34 patients, 2.9%) compared with first diagnosis (21 patients, 0.6%), pinvolvement at initial diagnosis had a significantly higher frequency in patients with complex aberrant karyotypes, high serum lactate dehydrogenase activity, French-American-British M5 subtype, FLT3-internal tandem duplication (ITD) mutations alone, and co-occurrence of a FLT3-ITD and NPM1 mutation. Furthermore, AML patients with CNS involvement at diagnosis had an inferior outcome compared with patients without CNS involvement even if treated with intrathecal chemotherapy with an overall survival of 11% versus 30% at 5 years, p=0.004. This study analyzed the largest data set of adult AML patients with proven CNS involvement reported so far. The data demonstrated very low prevalence of CNS involvement at initial diagnosis in adult patients with AML, and described new risk factors. In patients with risk factors, intense diagnostic and treatment strategies should be employed in the future.

    This study was aimed to evaluate the efficacy and safety of imatinib in the treatment of patients with adult Ph chromosome-positive acute lymphoblastic leukemia (Ph(+)ALL). A total of 32 diagnosed adult Ph(+)ALL patients from July 2007 to February 2014 in our hospital were retrospectively analyzed and were divided into two groups: imatinib plus chemotherapy group and traditional chemotherapy group. The differences between two groups were analysed in disease-free survival time (DFS), overall survival time (OS) and toxicity. The G banding technigue was used to analyse the karyotype, and the flow cytometry was applyed to detect the immune markers on surface of cells. The results showed that all patients expressed B cell and hematopietic stem/progenitor cell immune markers, out of them 21 patients (65.6%) were with myeloid antigens, 27 patients with simple Ph (+) phenotype and 5 patients with additional chromosome abnormality. The DFS and OS of the imatinib group were statistically longer than those of the traditional chemotherapy group (14.3 ± 4.7 months vs 10.7 ± 3.8 months) (P 0.05)). It is concluded that the all cases of adult Ph(+)ALL are with B cell phenotype and express hematopietic stem/progenitor cell antigen. They often accompanied by expression of myeloid antigens and additonal chromosome abnormality in genetics. The combination of imatinib with chemotherapy can prolong remission time and survival time for patients of non-hematopietic stem cell transplantation on the basis of no notably increasing the toxic effects.

    To compare the accuracy of the Loeb criteria, emergency department (ED) physicians' diagnoses, and Centers for Disease Control and Prevention (CDC) guidelines for acute bacterial infection in older adults with a criterion standard expert review. Prospective, observational study. Urban, tertiary-care ED. Individuals aged 65 and older in the ED, excluding those who were incarcerated, underwent a trauma, did not speak English, or were unable to consent. Two physician experts identified bacterial infections using clinical judgement, participant surveys, and medical records; a third adjudicated in cases of disagreement. Agreement and test characteristics were measured for ED physician diagnosis, Loeb criteria, and CDC surveillance guidelines. Criterion-standard review identified bacterial infection in 77 of 424 participants (18%) (18 (4.2%) lower respiratory, 19 (4.5%) urinary tract (UTI), 22 (5.2%) gastrointestinal, 15 (3.5%) skin and soft tissue). ED physicians diagnosed infection in 71 (17%), but there were 33 with under- and 27 with overdiagnosis. Physician agreement with the criterion standard was moderate for infection overall and each infection type (κ = 0.48-0.59), but sensitivity was low (<67%), and the negative likelihood ratio (LR(-)) was greater than 0.30 for all infections. The Loeb criteria had poor sensitivity, agreement, and LR(-) for lower respiratory (50%, κ = 0.55; 0.51) and urinary tract infection (26%, κ = 0.34; 0.74), but 87% sensitivity (κ = 0.78; LR(-) 0.14) for skin and soft tissue infections. CDC guidelines had moderate agreement but poor sensitivity and LR(-). Emergency physicians often under- and overdiagnose infections in older adults. The Loeb criteria are useful only for diagnosing skin and soft tissue infections. CDC guidelines are inadequate in the ED. New criteria are needed to aid ED physicians in accurately diagnosing infection in older adults. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics

    Studies of immune function during depression in persons without intellectual disability (ID) have revealed elevated levels of alpha2 macroglobulin (alpha2M) and an acute phase protein (APP) response. Clinical observation suggests that people with Down's syndrome (DS) may have associated genetic abnormalities in their immune systems. The APP response and alpha2M changes in depressed versus non-depressed adults with DS was the subject of the present study. The serum pan-proteinase inhibitor alpha2M, and the AP proteins c-reactive protein (CRP), alpha1 antitrypsin (alpha1AT), ceruloplasmin (Cp), beta2 Macroglobulin (beta2M), transthyretin (Trans), serum amyloid protein (SAP), and albumin (Alb) were measured in 38 adults with DS, 19 of whom were diagnosed with and 19 without depression using a sandwich enzyme-linked immunosorbent assay (ELISA). The DSM-IV criteria were used for diagnoses. Medical and neurological examinations excluded medical disorders associated with APP response. Only alpha2M and CRP were significantly different in the depressed versus non-depressed groups. The alpha2M was higher, a response similar to one observed in depressed people without ID, but the CRP was lower in the depressed group, especially in those subjects not on psychotropic medications, contrary to the expected APP response to depression. The results suggest that alpha2M elevation in depressed adults with DS is independent of the APP response. An alternative explanation for its elevation is proposed linking the core symptom of depression with the mammalian dormancy/hibernation process. Further studies are needed to confirm that alpha2M elevation is specific to depression and that it might provide a helpful marker for the diagnosis of depression in people with ID.

    Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are syndromes of severe respiratory failure that are associated with substantial mortality and morbidity. Artifical ventilatory support is commonly required and may exacerbate lung injury. Partial liquid ventilation (PLV) has been proposed as a less injurious form of ventilatory support for these patients. Although PLV has been shown to improve gas exchange and to reduce inflammation in experimental models of ALI, a previous systematic review did not find any evidence to support or refute its use in humans with ALI and ARDS. The primary objective of this review was to assess whether PLV reduced mortality (at 28 d, at discharge from the intensive care unit (ICU), at discharge from hospital and at one, two and five years) in adults with ALI or ARDS when compared with conventional ventilatory support.Secondary objectives were to determine how PLV compared with conventional ventilation with regard to duration of invasive mechanical ventilation, duration of respiratory support, duration of oxygen therapy, length of ICU stay, length of hospital stay, incidence of infection, long-term cognitive impairment, long-term health related quality of life, long- term lung function, long-term morbidity costs and adverse events. The following adverse events were considered: hypoxia (arterial PO2 blood pressure < 90 mm Hg sustained for longer than two minutes or requiring treatment with fluids or vasoactive drugs), bradycardia (heart rate < 50 beats per minute sustained for longer than one minute or requiring therapeutic intervention) and cardiac arrest (absence of effective cardiac output). In this updated review, we searched the Cochrane Central Register of Controlled Trials (CENTRAL Issue 10, 2012, in The Cochrane Library; MEDLINE (Ovid SP, 1966 to November 2012); EMBASE (Ovid SP, 1980 to November 2012) and CINAHL (EBSCOhost,1982 to November 2012) for published studies.

    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.

    The use of gold nanoparticles is increasing in medicine; however, their toxic effects remain to be elucidated. Studies show that gold nanoparticles can cross the blood-brain barrier, as well as accumulate in the brain. Therefore, this study was undertaken to better understand the effects of gold nanoparticles on rat brains. DNA damage parameters were evaluated in the cerebral cortex of adult rats submitted to acute and chronic administration of gold nanoparticles of two different diameters: 10 and 30nm. During acute administration, adult rats received a single intraperitoneal injection of either gold nanoparticles or saline solution. During chronic administration, adult rats received a daily single injection for 28 days of the same gold nanoparticles or saline solution. Twenty-four hours after either single (acute) or last injection (chronic), the rats were euthanized by decapitation, their brains removed, and the cerebral cortices isolated for evaluation of DNA damage parameters. Our study showed that acute administration of gold nanoparticles in adult rats presented higher levels of damage frequency and damage index in their DNA compared to the control group. It was also observed that gold nanoparticles of 30nm presented higher levels of damage frequency and damage index in the DNA compared to the 10nm ones. When comparing the effects of chronic administration of gold nanoparticles of 10 and 30nm, we observed that occurred significant different index and frequency damage, comparing with control group. However, there is no difference between the 10 and 30nm groups in the levels of DNA damage for both parameters of the Comet assay. Results suggest that gold nanoparticles for both sizes cause DNA damage for chronic as well as acute treatments, although a higher damage was observed for the chronic one.

Methods: All cases of acute epiglottitis admitted in ENT and Head and Neck Surgery ward of TUTH, Kathmandu, Nepal, from April 2001 to September 2007, were enrolled. Routine investigations including x-rays and blood cultures were done. The patients were further investigated to rule out the presence of Pulmonary Tuberculosis.The standard treatment protocol we used included Injection Ampicillin 500 mg intravenously six hourly for 72 hours followed by oral Ampicillin 500mg for 7 days, with analgesics and intravenous steroid (Hydrocortisone 200mg if required. Study Design: Prospective longitudinal study. Results: Majority of the patients presented with a history sore throat (83.3%, dysphagia (78.6% and odynophagia (78.6%. On examination all the patients were found to have swollen and congested epiglottis. Positive "Thumb sign" on plain X-ray soft tissue neck lateral view was found in almost all the patients (95.2%. Four patients presented with stridor and patient needed emergency tracheostomy. None of the investigations done to detect Pulmonary Tuberculosis was found to be positive. Conclusion: Acute epiglottitis is a rare disease which now occurs more commonly in adults. The annual prevalence of Acute Epiglottitis in adult in TUTH is 4.8 per 1000. This study did not find any association of acute epiglottitis with pulmonary tuberculosis.

    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.

    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

    Our knowledge about acute promyelocytic leukemia (APL) patients is mainly based on data from clinical trials, whereas population-based information is scarce. We studied APL patients diagnosed between 1997 and 2006 in the population-based Swedish Adult Acute Leukemia Registry. Of a total of 3897 acute leukemia cases, 3205 (82%) had non-APL acute myeloid leukemia (AML) and 105 (2.7%) had APL. The incidence of APL was 0.145 per 100,000 inhabitants per year. The median age at the time of diagnosis was 54 years; 62% were female and 38% male. Among younger APL patients, female sex predominated (89% of patients <40 years). Of the 105 APL patients, 30 (29%) died within 30 days (that is, early death (ED)) (median 4 days) and 28 (26%) within 14 days from diagnosis. In all, 41% of the EDs were due to hemorrhage; 35% of ED patients never received all-trans-retinoic acid treatment. ED rates increased with age but more clearly with poor performance status. ED was also associated with high white blood cells, lactate dehydrogenase, creatinine, C-reactive protein and low platelet count. Of non-ED patients, 97% achieved complete remission of which 16% subsequently relapsed. In total, 62% are still alive at 6.4 years median follow-up. We conclude that ED rates remain very high in an unselected APL population.

    This article presents the results of a systematic review of descriptive cohort studies on the dynamics of glycaemia among adults admitted to hospital with acute stroke. Hyperglycaemia is common among adults admitted to hospital with stroke. Systematic review. A search for descriptive cohort studies published between January 1996-June 2011, was conducted in MEDLINE, PubMed and Embase electronic databases. The search was performed using the terms 'stroke', 'hyperglycaemia' and/or 'glucose' combined and limited to adults and English language publications. Searching of citations from identified studies supplemented the electronic searches. A systematic review was conducted of eight studies, meeting the criteria of: (1) descriptive cohort studies; (2) adults admitted to hospital with acute stroke; and (3) glycaemic status monitored over at least two consecutive days from admission to hospital. The review adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis standards. The dynamics of glycaemia after stroke has been investigated in seven prospective cohort studies and one retrospective study. The patterns that emerged were persisting normoglycaemia, transient hyperglycaemia, persisting hyperglycaemia and delayed hyperglycaemia. Surges in glycaemia are likely on days 2 and 3 and some adults will not exhibit hyperglycaemia till day 7. Further large cohort studies are required to explore the dynamic of glycaemia after stroke for at least 1 week duration. The timing of formal screening for diabetes mellitus is important, as early screening may overestimate detection rates. © 2012 Blackwell Publishing Ltd.

    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.

    PR (PRDI-BF1 and RIZ) domain proteins (PRDM) are a subfamily of the kruppel-like zinc finger gene products that modulate cellular processes such as differentiation, cell growth and apoptosis. PRDM5 is a recently identified family member that functions as a transcriptional repressor and behaves as a putative tumor suppressor in different types of cancer. However, the expression and function of PRDM5 in spinal cord injury (SCI) are still unknown. In the present study, we have performed an acute SCI model in adult rats and investigated the dynamic changes of PRDM5 expression in the spinal cord. We found that PRDM5 protein levels gradually increased, reaching a peak at day 5 and then gradually declined to a normal level at day 14 after SCI with Western blot analysis. Double immunofluorescence staining showed that PRDM5 immunoreactivity was found in neurons, astrocytes and microglia. However, the expression of PRDM5 was increased predominantly in neurons. Additionally, colocalization of PRDM5/active caspase-3 was been respectively detected in neurons. In vitro, we found that depletion of PRDM5 by short interfering RNA, obviously decreases neuronal apoptosis. In summary, this is the first description of PRDM5 expression in SCI. Our results suggested that PRDM5 might play crucial roles in CNS pathophysiology after SCI and this research will provide new drug targets for clinical treatment of SCI.

    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.

    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.

    We sought to examine the occurrence of acute compartment syndrome (ACS) in the cohort of patients with tibial diaphyseal fractures and to detect associated risk factors that could predict this occurrence. A total of 1,125 patients with tibial diaphyseal fractures that were treated in our centre were included into this retrospective cohort study. All patients were treated with surgical fixation. Among them some were complicated by ACS of the leg. Age, gender, year and mechanism of injury, injury severity score (ISS), fracture characteristics and classifications and the type of fixation, as well as ACS characteristics in affected patients were studied. Of the cohort of patients 772 (69 %) were male (mean age 39.60 ± 15.97 years) and the rest were women (mean age 45.08 ± 19.04 years). ACS of the leg occurred in 87 (7.73 %) of all tibial diaphyseal fractures. The mean age of those patients that developed ACS (33.08 ± 12.8) was significantly lower than those who did not develop it (42.01 ± 17.3, P leg associated with tibial diaphyseal fractures in adults.

    2014-02-01

    The idea behind this thesis is to present how ARS and especially acute maxillary sinusitis in adults is diagnosed and treated in general practice. The study extends over many years, beginning with the first survey in 1991. Based on doctors' answers, we then investigated the diagnostic values ​​of the symptoms, signs and examinations which the doctors reported using. All patients over 18 years suspected of acute maxillary sinusitis were included consecutively and only once and, after a clinical examination with the GP, they were offered the opportunity to enter into the prospective study referred to acute CT scan and by changes in the CT, immediately referred to sinus puncture. Both examinations were conducted at Aalborg Hospital. The disease was found most frequently in younger and 2/3 were women. The reason for this gender difference is unknown. We have assessed the diagnostic values of the symptoms, objective findings and investigations ​​using 3 different reference standards: sinus puncture, microbiological diagnosis and CT scan described in three articles. In all examinations, it appeared that the usual signs and symptoms of acute maxillary sinusitis occur almost equally often and with a few exceptions in patients, with and without pus in the sinus cavities. Pain in the sinus cavities occurring in 95% of patients, and only elevated levels of CRP and ESR are significantly and independently associated with pus in the sinus cavities. This finding is surprising, because they are two nonspecific markers. CRP tested by near-patient testing has, within the investigations period, been introduced in general practice, and from 1999 the doctors also get reimbursed for performing the test. We have on this background originally defined a clinical criterion with pain over the sinuses accompanied by elevated values ​​of CRP and/or ESR giving a sensitivity of 0.82, specificity 0.57, ppv 0.68 and npv 0.74. But looking at the ROC curve we suggest that a more clinical

    Background The t(9;22) and t(4;11) chromosomal translocations, which generate the BCR-ABL and MLL-AF4 fusion genes, define high-risk subtypes of acute lymphoblastic leukemia in adults. However, the prognostic impact of other rarer fusion genes is less well established in adult acute lymphoblastic leukemia than in the childhood form. Design and Methods In the context of the German Multicenter Therapy Study Group for Adult Acute Lymphoblastic Leukemia (GMALL) we used reverse transcriptase polymerase chain reaction to investigate 441 cases of BCR-ABL- and MLL-AF4-negative B-precursor acute lymphoblastic leukemia for the TCF3-PBX1 (E2A-PBX1) and ETV6-RUNX1 (TEL-AML1) fusion transcripts generated by the t(1;19)(q23;p13.3) and t(12;21)(p13;q22) translocations. Both are well-known molecular alterations in pediatric acute lymphoblastic leukemia in which they have favorable prognostic implications. Results We identified 23 adult patients with TCF3-PBX1 and ten with ETV6-RUNX1. In contrast to previous reports we found no significant difference in overall survival between TCF3-PBX1-positive and -negative patients. At 2 years after diagnosis all the ETV6-RUNX1-positive patients were alive and in continuous complete remission, but their long-term outcome was negatively affected by late relapses. TCF3-PBX1-positive patients exhibited a characteristic CD34−/CD33− and mostly cyIg+ immunophenotype. ETV6-RUNX1 only occurred in patients under 35 years old and was associated with a significantly lower white blood count. Conclusions In contrast to previous suggestions, adult patients with TCF3-PBX1-positive acute lymphoblastic leukemia do not appear to have a worse outcome than their negative counterparts. ETV6-RUNX1-positive patients had a very favorable performance status during the first few years but their long-term survival was negatively affected by late relapses. Both groups of patients are characterized by distinct clinicobiological features which facilitate their

    Mental health nurses work with acutely unwell patients, and the busy setting is characterised by unpredictable events. This paper is a report of a review conducted to identify, analyse and synthesize research in adult acute inpatient mental health units, which focused on nurse-patient interaction. Several electronic databases were searched using relevant keywords to identify studies published from 1999-present. Qualitative studies published in English were included if they specifically investigated nurse-patient interaction in acute inpatient care in adult settings. Eighteen studies were included (23 papers). Findings were grouped into the following six categories: 1) sophisticated communication; 2) subtle discriminations; 3) managing security parameters; 4) ordinary communication; 5) reliance on colleagues; and 6) personal characteristics. These studies of acute inpatient mental health units reveal that nurse communication involves interpersonal approaches and modalities that exemplify highly developed communication and personal skills designed specifically for this challenging setting. Further quality research should focus on the conditions that enable the development of therapeutic interactional skills and the relationship of these skills to the nuanced context in which they are practiced.

    Stress is a potent modulator of the mammalian brain. The highly conserved stress hormone response influences many brain regions, particularly the hippocampus, a region important for memory function. The effect of acute stress on the unique population of adult neural stem/progenitor cells (NPCs) that resides in the adult hippocampus is unclear. We found that acute stress increased hippocampal cell proliferation and astrocytic fibroblast growth factor 2 (FGF2) expression. The effect of acute stress occurred independent of basolateral amygdala neural input and was mimicked by treating isolated NPCs with conditioned media from corticosterone-treated primary astrocytes. Neutralization of FGF2 revealed that astrocyte-secreted FGF2 mediated stress-hormone-induced NPC proliferation. 2 weeks, but not 2 days, after acute stress, rats also showed enhanced fear extinction memory coincident with enhanced activation of newborn neurons. Our findings suggest a beneficial role for brief stress on the hippocampus and improve understanding of the adaptive capacity of the brain. DOI:http://dx.doi.org/10.7554/eLife.00362.001.

    Gene expression studies have consistently identified a HOXA-overexpressing cluster of T-cell acute lymphoblastic leukemias, but it is unclear whether these constitute a homogeneous clinical entity, and the biological consequences of HOXA overexpression have not been systematically examined. We characterized the biology and outcome of 55 HOXA-positive cases among 209 patients with adult T-cell acute lymphoblastic leukemia uniformly treated during the Group for Research on Adult Acute Lymphoblastic Leukemia (GRAALL)-2003 and -2005 studies. HOXA-positive patients had markedly higher rates of an early thymic precursor-like immunophenotype (40.8% versus 14.5%, P=0.0004), chemoresistance (59.3% versus 40.8%, P=0.026) and positivity for minimal residual disease (48.5% versus 23.5%, P=0.01) than the HOXA-negative group. These differences were due to particularly high frequencies of chemoresistant early thymic precursor-like acute lymphoblastic leukemia in HOXA-positive cases harboring fusion oncoproteins that transactivate HOXA Strikingly, the presence of an early thymic precursor-like immunophenotype was associated with marked outcome differences within the HOXA-positive group (5-year overall survival 31.2% in HOXA-positive early thymic precursor versus 66.7% in HOXA-positive non-early thymic precursor, P=0.03), but not in HOXA-negative cases (5-year overall survival 74.2% in HOXA-negative early thymic precursor versus 57.2% in HOXA-negative non-early thymic precursor, P=0.44). Multivariate analysis further revealed that HOXA positivity independently affected event-free survival (P=0.053) and relapse risk (P=0.039) of chemoresistant T-cell acute lymphoblastic leukemia. These results show that the underlying mechanism of HOXA deregulation dictates the clinico-biological phenotype, and that the negative prognosis of early thymic precursor acute lymphoblastic leukemia is exclusive to HOXA-positive patients, suggesting that early treatment intensification is currently

    Topical analgesic drugs are used for a variety of painful conditions. Some are acute, typically strains or sprains, tendinopathy, or muscle aches. Others are chronic, typically osteoarthritis of hand or knee, or neuropathic pain. To provide an overview of the analgesic efficacy and associated adverse events of topical analgesics (primarily nonsteroidal anti-inflammatory drugs (NSAIDs), salicylate rubefacients, capsaicin, and lidocaine) applied to intact skin for the treatment of acute and chronic pain in adults. We identified systematic reviews in acute and chronic pain published to February 2017 in the Cochrane Database of Systematic Reviews (the Cochrane Library). The primary outcome was at least 50% pain relief (participant-reported) at an appropriate duration. We extracted the number needed to treat for one additional beneficial outcome (NNT) for efficacy outcomes for each topical analgesic or formulation, and the number needed to treat for one additional harmful outcome (NNH) for adverse events. We also extracted information on withdrawals due to lack of efficacy or adverse events, systemic and local adverse events, and serious adverse events. We required information from at least 200 participants, in at least two studies. We judged that there was potential for publication bias if the addition of four studies of typical size (400 participants) with zero effect increased NNT compared with placebo to 10 (minimal clinical utility). We extracted GRADE assessment in the original papers, and made our own GRADE assessment. Thirteen Cochrane Reviews (206 studies with around 30,700 participants) assessed the efficacy and harms from a range of topical analgesics applied to intact skin in a number of acute and chronic painful conditions. Reviews were overseen by several Review Groups, and concentrated on evidence comparing topical analgesic with topical placebo; comparisons of topical and oral analgesics were rare.For at least 50% pain relief, we considered evidence was

    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.

    BACKGROUND: Studies have reported that spinal cord injury can induce the reactive proliferation of ependymal cells and secondarily cause the apoptosis of nerve cells. However, there is no generally accepted theory on the apoptotic characteristics of ependymal cells in the injured spinal cord.OBJECTIVE: To observe the reactive proliferation and apoptosis of ependymal cells in adult rats following acute spinal cord injury.DESIGN, TIME AND SETTING: A randomized control study based on neuropathology was performed in the Third Military Medical University of Chinese PLA between 2005 and 2007.MATERIALS: Forty healthy, adult, Wistar rats were included in the present study.METHODS: Moderate spinal cord injury was established in twenty rats using Feeney's method, while the remaining 20 rats served as controls and were only treated with laminectomy. All rats were injected intraperitoneally with 1.25 mL of BrdU solution (10 mg BrdU/mL saline) 3 times at 4 hours intervals during the 12 hours prior to sacrifice.MAIN OUTCOME MEASURES: Ependymal cell proliferation and apoptosis in the rat spinal cord were determined by BrdU and nestin immunofluorescence double-labeling, as well as the TUNEL method, at 1, 3, 7, and 14 days after operation.RESULTS: In the moderate spinal cord injury rats, nestin expression was observed in the cytoplasm of ependymal cells. One day immediately following surgery, ependymal cells were BrdU-labeled. The number of BrdU-positive cells increased at 3 days, reached a peak at 7 days, and gradually reduced thereafter. The ependyma developed ti'om a constitutive monolayer cells to a multi-layer cell complex. Some BrdU/Nestin double-positive ependymal cells migrated out from the ependyma. TUNEL-positive cells were also detected in the ependyma in the central region, as well as ischemic regions of the injured spinal cord. In addition, TUNEL-positive cells were visible in the ependyma. No TUNEL-positive ependymal cells were observed in the normal spinal cord

    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.

    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

    Many adults with epilepsy have breakthrough seizures despite treatment with antiepileptic drugs (AEDs), requiring them to have a rescue medication as part of a comprehensive treatment plan. We evaluated the effectiveness and tolerability of rectal diazepam in the treatment of breakthrough seizures in adult patients with epilepsy. We identified 50 such patients who had used diazepam rectal gel for clusters of seizures defined as acute repetitive seizures, prolonged seizures, or both, in the previous 18 months. Information on diagnoses, dose, frequency of use, reasons for use, safety, and efficacy was collected. Diazepam rectal gel was effective in stopping seizures in 45 patients (90%). Somnolence was reported in most patients, but no other adverse events were reported. Diazepam rectal gel demonstrates efficacy and tolerability as a seizure rescue medication for adult patients with a variety of seizure types, and may help improve quality of life.

    We examined the acute effect of physical exercise on prefrontal cortex activity in older adults using functional near-infrared spectroscopy (NIRS). Fourteen older adults visited our laboratory twice: once for exercise and once for the control condition. On each visit, subjects performed working memory tasks before and after moderate intensity exercise with a cycling ergo-meter. We measured the NIRS response at the prefrontal cortex during the working memory task. We found that physical exercise improved behavioral performance of the working memory task compared with the control condition. Moreover, NIRS analysis showed that physical exercise enhanced the prefrontal cortex activity, especially in the left hemisphere, during the working memory task. These findings suggest that the moderate intensity exercise enhanced the prefrontal cortex activity associated with working memory performance in older adults.

    Full Text Available Background: Poor cerebral perfusion may contribute to cognitive impairment in type 2 diabetes mellitus (T2DM. We conducted a randomized controlled trial to test the hypothesis that resveratrol can enhance cerebral vasodilator function and thereby alleviate the cognitive deficits in T2DM. We have already reported that acute resveratrol consumption improved cerebrovascular responsiveness (CVR to hypercapnia. We now report the effects of resveratrol on neurovascular coupling capacity (CVR to cognitive stimuli, cognitive performance and correlations with plasma resveratrol concentrations. Methods: Thirty-six T2DM adults aged 40–80 years were randomized to consume single doses of resveratrol (0, 75, 150 and 300 mg at weekly intervals. Transcranial Doppler ultrasound was used to monitor changes in blood flow velocity (BFV during a cognitive test battery. The battery consisted of dual-tasking (finger tapping with both Trail Making task and Serial Subtraction 3 task and a computerized multi-tasking test that required attending to four tasks simultaneously. CVR to cognitive tasks was calculated as the per cent increase in BFV from pre-test basal to peak mean blood flow velocity and also as the area under the curve for BFV. Results: Compared to placebo, 75 mg resveratrol significantly improved neurovascular coupling capacity, which correlated with plasma total resveratrol levels. Enhanced performance on the multi-tasking test battery was also evident following 75 mg and 300 mg of resveratrol. Conclusion: a single 75 mg dose of resveratrol was able to improve neurovascular coupling and cognitive performance in T2DM. Evaluation of benefits of chronic resveratrol supplementation is now warranted.

    Objective HIV-infected patients in Africa are vulnerable to severe recurrent infection with Streptococcus pneumoniae, but no effective preventive strategy has been developed. We set out to determine which factors influence in-hospital mortality and long-term survival of Malawians with invasive pneumococcal disease. Design, setting and patients Acute clinical features, inpatient mortality and long-term survival were described among consecutively admitted hospital patients with S. pneumoniae in the blood or cerebrospinal fluid. Factors associated with inpatient mortality were determined, and patients surviving to discharge were followed to determine their long-term outcome. Results A total of 217 patients with pneumococcal disease were studied over an 18-month period. Among these, 158 out of 167 consenting to testing (95%) were HIV positive. Inpatient mortality was 65% for pneumococcal meningitis (n = 64), 20% for pneumococcaemic pneumonia (n = 92), 26% for patients with pneumococcaemia without localizing signs (n = 43), and 76% in patients with probable meningitis (n = 17). Lowered consciousness level, hypotension, and age exceeding 55 years at presentation were associated with inpatient death, but not long-term outcome in survivors. Hospital survivors were followed for a median of 414 days; 39% died in the community during the study period. Outpatient death was associated with multilobar chest signs, oral candidiasis, and severe anaemia as an inpatient. Conclusion Most patients with pneumococcal disease in Malawi have HIV co-infection. They have severe disease with a high mortality rate. At discharge, all HIV-infected adults have a poor prognosis but patients with multilobar chest signs or anaemia are at particular risk.

    BACKGROUND Acute kidney injury (AKI) after coronary artery bypass graft (CABG) surgery is associated with increased postoperative morbidity and mortality. We hypothesized that increased plasma neutrophil gelatinase-associated lipocalin (NGAL) measured immediately after separating from cardiopulmonary bypass (CPB) would predict AKI after CABG surgery. METHODS In a retrospective observational study, we examined the value of plasma NGAL measured after CPB for predicting the risk of developing AKI (defined as a ≥50% increase in serum creatinine from preoperative levels) in 879 patients after CABG surgery using multivariable logistic regression. Area under the curve of receiver operating characteristic curves was analyzed to assess sensitivities, specificities, and cutoff points for postoperative plasma NGAL levels to predict AKI. RESULTS Seventy-five patients (8.6%) developed postoperative AKI. Plasma NGAL levels measured after CPB were higher in patients who subsequently developed AKI than in those who did not (AKI: 268.8 ng/mL [207.5–459.5 ng/mL], median [interquartile range], vs no AKI: 238.4 ng/mL [172.0–319.1 ng/mL]; P postoperative day 4. An optimal serum plasma NGAL cutoff of 353.5 ng/mL at the post-CPB time point had a sensitivity of 38.7%, specificity of 81.5%, and a positive predictive value of 16.3% for predicting AKI. In our multivariate regression model, post-CPB plasma NGAL levels >353.5 ng/mL were independently associated with postoperative AKI (odds ratio, 2.3; 95% confidence interval, 1.5–6.5; P = 0.002). CONCLUSION An early increase of post-CPB plasma NGAL is associated with AKI in adult patients undergoing CABG surgery, although the sensitivity is low. Therefore, assessing early plasma NGAL alone has limited utility for predicting AKI in this patient population. PMID:20435938

    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

    Attention to patients with acute minor-illnesses requesting same-day consultation represents a major burden in primary care. The workload is assumed by general practitioners in many countries. A number of reports suggest that care to these patients may be provided, at in least in part, by nurses. However, there is scarce information with respect to the applicability of a program of nurse management for adult patients with acute minor-illnesses in large areas. The aim of this study is to assess the effectiveness of a program of nurse algorithm-guided care for adult patients with acute minor illnesses requesting same-day consultation in primary care in a largely populated area. A cross-sectional study of all adult patients seeking same day consultation for 16 common acute minor illnesses in a large geographical area with 284 primary care practices. Patients were included in a program of nurse case management using management algorithms. The main outcome measure was case resolution, defined as completion of the algorithm by the nurse without need of referral of the patient to the general practitioner. The secondary outcome measure was return to consultation, defined as requirement of new consultation for the same reason as the first one, in primary care within a 7-day period. During a two year period (April 2009-April 2011), a total of 1,209,669 consultations were performed in the program. Case resolution was achieved by nurses in 62.5% of consultations. The remaining cases were referred to a general practitioner. Resolution rates ranged from 94.2% in patients with burns to 42% in patients with upper respiratory symptoms. None of the 16 minor illnesses had a resolution rate below 40%. Return to consultation during a 7-day period was low, only 4.6%. A program of algorithms-guided care is effective for nurse case management of patients requesting same day consultation for minor illnesses in primary care.

    Full Text Available Intestinal Malrotation in adults is twisting of the intestines that lead to mal positioning of the bowels and malfixation of the mesentery, blocking the digestive tract and preventing the proper passage of food. Midgut malrotation is a congenital anomaly in the embryological development of the foetal intestinal rotation. It has been estimated that it affects approximately 1 in 500 l ive births . [ 1 ] Symptomatic malrotation is estimated to occur in 1 in 6000 live births . [ 2 ] Traditionally, intestinal malrotation has been considered primarily a disease of infancy with infrequent occurrence beyond the first year of life. Adult midgut malrotation is very rare and its incidence has been reported to be between 0. 0001% and 0. 19% . [ 3 , 4 ] Most adult diagnoses of midgut malrotation are made in asymptomatic patients; either on imaging investigations for unrelated conditions or at operations for other pathology. However, there are a small proportion of affected adults who may present with acu te or chronic symptoms of intestinal obstruction or intermittent and recurrent abdominal pain. The true diagnosis in this age group is fraught with immense difficulty, especially because the typical presentation is with non - specific symptoms and the fact t hat adult Surgeons usually have low index of suspicion and may not consider the diagnosis a possibility in the initial evaluation of adult patients with abdominal pain. We report a rare case of an 36 year old patient presented as acute intestinal obstruct ion due to midgut malrotation

    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.

    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 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.

    Full Text Available Abstract Introduction Acute kidney injury in the setting of adult minimal change disease is associated with proteinuria, hypertension and hyperlipidemia but anemia is usually absent. Renal biopsies exhibit foot process effacement as well as tubular interstitial inflammation, acute tubular necrosis or intratubular obstruction. We recently managed a patient with unique clinical and pathological features of minimal change disease, who presented with severe anemia and acute kidney injury, an association not previously reported in the literature. Case presentation A 60-year-old Indian-American woman with a history of hypertension and diabetes mellitus for 10 years presented with progressive oliguria over 2 days. Laboratory data revealed severe hyperkalemia, azotemia, heavy proteinuria and progressively worsening anemia. Urine eosinophils were not seen. Emergent hemodialysis, erythropoietin and blood transfusion were initiated. Serologic tests for hepatitis B, hepatitis C, anti-nuclear antibodies, anti-glomerular basement membrane antibodies and anti-neutrophil cytoplasmic antibodies were negative. Complement levels (C3, C4 and CH50 were normal. Renal biopsy unexpectedly displayed 100% foot process effacement. A 24-hour urine collection detected 6.38 g of protein. Proteinuria and anemia resolved during six weeks of steroid therapy. Renal function recovered completely. No signs of relapse were observed at 8-month follow-up. Conclusion Adult minimal change disease should be considered when a patient presents with proteinuria and severe acute kidney injury even when accompanied by severe anemia. This report adds to a growing body of literature suggesting that in addition to steroid therapy, prompt initiation of erythropoietin therapy may facilitate full recovery of renal function in acute kidney injury.

    Aging in both humans and rodents appears to be accompanied by physiological changes that increase biologic sensitivity to ethanol (EtOH) intoxication. However, animal models designed to investigate this increased alcohol sensitivity have yet to be established. For this reason, we sought to determine whether acute EtOH administration produces differential effects on motor coordination and spatial cognition in young adult and aged rats. Male young adult (postnatal day 70 to 72) and aged (~18 months) Sprague-Dawley rats were assessed on 2 motor tasks (the accelerating rotarod [RR] and the aerial righting reflex [ARR]) and a single cognitive performance task (the Morris water maze [MWM]). Following acute EtOH exposure via intraperitoneal injection, animals' performance was reassessed. Aged rats showed a dramatic increase in EtOH-induced ataxia on the RR and the ARR relative to young adult animals. Similarly, results from the MWM revealed that aged animals had slightly greater EtOH-induced impairments compared with young adult animals. Importantly, the increased impairments produced by EtOH were not due to differential blood EtOH levels. We demonstrate for the first time that aged rats show greater EtOH-induced deficits compared with young adults in tasks of motor and cognitive performance. The possible role of protein kinase C as a mechanism for increased sensitivity to the motor-impairing effects of EtOH is discussed. Given the high prevalence of alcohol use among the elderly, increased vulnerability to alcohol-induced deficits may have a profound effect on injury in this population.

    Recovery-oriented care acknowledges the unique journey that consumers lead with the aim of regaining control of their lives in order to live a good life. Recovery has become a dominant policy-directed model of many mental health care organizations, but in older-adult acute mental health inpatient settings, nurses do not have a clear description of how to be recovery-oriented. The aims of this study were to determine the extent to which elements of existing nursing practice resemble the domains of recovery-oriented care and provide a baseline understanding of practice in preparation for transformation to recovery-oriented mental health care provision. An exploratory, qualitative research design was used to meet the research aims. A purposive sample of mental health nurses (N = 12) participated in focus groups in three older-adult inpatient settings in Australia. A general inductive approach was used to analyze the qualitative data. The mental health nurses in this study readily discussed aspects of their current practice within the recovery domains. They described pragmatic ways to promote a culture of hope, collaborative partnerships, meaningful engagement, autonomy and self-determination, and community participation and citizenship. Nurses also discussed challenges and barriers to recovery-oriented care in older-adult acute mental health settings. This study identified a reasonable baseline understanding of practice in preparation for transformation to recovery-oriented older-adult mental healthcare provision. A concerted drive focused on recovery education is required to effectively embed a recovery-orientated paradigm into older-adult mental health settings.

    Spinal cord injury (SCI) causes severe and long lasting motor and sensory deficits, chronic pain, and autonomic dysreflexia. (-)-epigallocatechin-3-gallate (EGCG) has shown to produce neuroprotective effect in a broad range of neurodegenerative disease animal models. This study designed to test the efficacy of intravenous infusion of EGCG for 36 h, in acutely injured rats' spinal cord: within first 4 h post-injury and, in chronically SC injured rats: after one year of injury. Functional outcomes measured using standard BBB scale, The Louisville Swim Scale (LSS) and, pain behavior assessment tests. 72 Female adult rats subjected to moderate thoracic SCI using MASCIS Impactor, blindly randomized as the following: (I) Acute SCI + EGCG (II) Acute SCI + saline. (III) Chronic SCI + EGCG. (IV) Chronic SCI + saline and, sham SCI animals. EGCG i.v. treatment of acute and, chronic SCI animals resulted in significantly better recovery of motor and sensory functions, BBB and LSS (P spinal cord increased (P < 0.001). Percent areas of GAP-43 and GFAP immunohistochemistry showed significant (P < 0.05) increase. We conclude that the therapeutic window of opportunity for EGCG to depict neurological recovery in SCI animals, is viable up to one year post SCI when intravenously infused for 36 h.

    In a double-blind, controlled randomized trial, 88 adult patients with acute diarrhea (more than three watery stools per day) received either 400 mg of nifuroxazide twice daily or placebo for 5 days. The mean duration of diarrhea in the nifuroxazide group was 2.09 days versus 3.26 days in the placebo group (p less than 0.004). The number of bowel movements per day diminished and mucus disappeared more quickly in patients treated by nifuroxazide than in patients of the placebo group. Nifuroxazide was well tolerated and no side effects were observed. Nifuroxazide is an effective therapy for acute diarrhea and can be prescribed from the onset of diarrhea without waiting for stool culture results which can be late or negative.

    The purpose of this study is to evaluate the acute toxicity of oral exposure to nanoscale zinc powder in mice. The healthy adult male and female mice were gastro-intestinally administered at a dose of 5 g/kg body weight with two size particles, nanoscale zinc (N-Zn) and microscale zinc (M-Zn) powder, while one group mice treated with sodium carboxy methyl cellulose was used as the control. The symptoms and mortality after zinc powder treatment were recorded. The effects of particles on the blood-element, the serum biochemical level and the blood coagulation were studied after 2 weeks of administration. The organs were collected for histopathological examination. The N-Zn treated mice showed more severe symptoms of lethargy, vomiting and diarrhea in the beginning days than the M-Zn mice. Deaths of two mice occurred in the N-Zn group after the first week of treatment. The mortalities were confirmed by intestinal obstruction of the nanoscale zinc aggregation. The biochemical liver function tests of serum showed significantly elevated ALT, AST, ALP, and LDH in the M-Zn mice and ALT, ALP, and LDH in the N-Zn mice compared with the controls (Pnano-scale zinc powders. The clinical changes were observed in the two treated group mice as well. The levels of the above enzymes were generally higher in the M-Zn mice than in the N-Zn mice, which implied that M-Zn powder could induce more severe liver damage than N-Zn. The biochemical renal function tests of serum BUN and CR in the M-Zn mice markedly increased either compared with the N-Zn mice or with the controls (P<0.05), but no significant difference was found between the N-Zn and the control mice. However, severe renal lesions were found by the renal histopathological examination in the N-Zn exposed mice. Therefore, we concluded that severe renal damage could occur in the N-Zn treated mice, though no significant change of blood biochemical levels occurred. Blood-element test showed that in the N-Zn mice, PLT and RDW

    Full Text Available ABSTRACT. BACKGROUND: Fever is a burning issue in the tropics and the mos t common cause of morbidity. Quite frequently this fever goes undi agnosed because of many reasons like the lack of diagnostic facilities, insufficient epidemi ological data available on causes of fever, and so on. This research study was aimed to find out the e tiology and clinical markers of Acute Undifferentiated Febrile Illness [AUFI] among the r ural population of Southern India. METHODOLOGY: This prospective, observational study was conducted at Government Villupuram Medical College and Hospital, a rural ter tiary care centre in Tamil Nadu, India. Consecutive hospitalised adult patients [>16 years] with AUFI[5-14 days fever] were enrolled into the study from August 2010 to February 2012 [1 8 months].Upon enrollment, detailed history was recorded, physical examination done and basic blood tests including biochemical examination, smear study for malaria, blood culture s and serology for the commonly encountered infections were done according to study protocol. The patients were followed up until clinical recovery and convalescence. The data were entered in MS excel and analyzed using Epi-info software 2008 version. RESULTS: A total of 403 patients were included in the study . The distribution of AUFI included Malaria 133[33%], Typhoid 83[20.59%], Dengue 42[10.4%], Leptospirosis 25[6.2%], and other causes 36[8.9%] and unknown cause 84[20.84%]. Malaria patients were significantly associated with jaundice , altered mentation, travel outside the district, elevated AST/ALT levels, thrombocytopenia and splenomegaly. Typhoid fever was associated with longer fever duration, abdominal pai n, coated tongue, relative bradycardia, normal platelet counts and low leucocyte count. Deng ue fever could be predicted by rash, pruritis, petechiae ,retro-orbital pain and low platele t counts. Leptospirosis patients showed significant association with conjunctival suffusion , muscle

    Acute post-infectious glomerulonephritis (APIGN) is uncommon in adults. It is widely recognized that the prognosis of APIGN is good in children. There is however little information about its long-term prognosis in adults. Between December 1976 and October 2004, 148 adult cases of APIGN were managed in our center. We retrospectively reviewed these patients' records and evaluated their clinical course and outcome. The mean age of studied patients was 36 ± 15 years, and the male to female ratio was 2.3. The most common site of preceding infection was the respiratory tract (68.8%). At presentation, 89.2% had nephritic syndrome and 9.4% had rapidly progressive glomerulonephritis. Proteinuria was observed in 99.3%, hematuria in 95.3%, peripheral edema in 89.2% and hypertension in 81.8%. Most patients (60.7%) had acute kidney injury and four patients (2.7%) required dialysis. Renal biopsy showed diffuse endocapillary proliferative glomerulonephritis in 88.8% of patients, associated with extracapillary proliferation in 12%. After a median follow-up of 2.5 year, only two patients died and 16.12% of patients had persistent clinical and/or biological abnormality. Chronic kidney disease was noted in 10 patients (6.75%) including four patients (2.7%) who progressed to end-stage renal disease. Poor prognostic factors included nephrotic range proteinuria, extracapillary proliferation in renal biopsy, acute kidney injury and the need for dialysis. In this cohort of patients, APIGN progressed to chronic kidney disease in less than 10% of patients.

    Myeloid-derived suppressor cells (MDSCs) are thought to help provide a cellular microenvironments in many solid tumors, in which transformed cells proliferate, acquire new mutations, and evade host immunosurveillance. In the present study, we found that MDSCs (CD33 + CD11b + HLA-DR(low/neg)) in bone marrow were significantly increased in adult acute myeloid leukemia (AML) patients. MDSCs levels in newly diagnosed AML patients correlated well with extramedullary infiltration and plasma D-dimer levels. Remission rates in the MDSCs > 1500 group and MDSCs phenotype. These cells appear to impact the clinical course and prognosis of AML. This data may provide potentially important targets for novel therapies.

    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

    This is an updated version of the original Cochrane overview published in Issue 9, 2011. That overview considered both efficacy and adverse events, but adverse events are now dealt with in a separate overview.Thirty-nine Cochrane reviews of randomised trials have examined the analgesic efficacy of individual drug interventions in acute postoperative pain. This overview brings together the results of those individual reviews and assesses the reliability of available data. To summarise the efficacy of pharmaceutical interventions for acute pain in adults with at least moderate pain following surgery who have been given a single dose of oral analgesic. We identified systematic reviews in the Cochrane Database of Systematic Reviews in The Cochrane Library through a simple search strategy. All reviews were overseen by a single review group, had a standard title, and had as their primary outcome the number of participants with at least 50% pain relief over four to six hours compared with placebo. For individual reviews, we extracted the number needed to treat for an additional beneficial outcome (NNT) for this outcome for each drug/dose combination, and also the percentage of participants achieving at least 50% maximum pain relief, the mean of mean or median time to remedication, and the percentage of participants remedicating by six, eight, 12, or 24 hours. Where there was adequate information for pairs of drug and dose (at least 200 participants, in at least two studies), we defined the addition of four comparisons of typical size (400 participants in total) with zero effect as making the result potentially subject to publication bias and therefore unreliable. The overview included 39 separate Cochrane Reviews with 41 analyses of single dose oral analgesics tested in acute postoperative pain models, with results from about 50,000 participants in approximately 460 individual studies. The individual reviews included only high-quality trials of standardised design

    Lineage switch from AML to ALL is an extremely rare phenomenon, and we report the case of an adult diagnosed with AML at 46 years of age who relapsed with ALL. At initial diagnosis, blast cell morphology and immunophenotyping were consistent with the diagnosis of M4-AML. Complete remission was achieved, and the patient underwent autologous BMT. At relapse, six months after ABMT, blast cells were different from those seen at initial diagnosis, for morphology (L2-ALL), cytochemistry, and immunophenotyping. The karyotype was normal at both diagnosis and relapse. No evidence of bcr-abl fusion genes was found by RT-PCR. Monoclonal IgH and TCR gamma gene rearrangement were evidenced by PCR analysis at relapse but not on blast cells at AML diagnosis.

    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.

    Trisomy 8 (+8) is one of the most common cytogenetic abnormalities in adult patients with acute myeloid leukemia (AML). However, the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) in adult patients with AML harboring +8 remains unclear. To evaluate, the outcome and prognostic factors in patients with AML harboring +8 as the only chromosomal abnormality or in association with other abnormalities, we retrospectively analyzed the Japanese registration data of 631 adult patients with AML harboring +8 treated with allogeneic HSCT between 1990 and 2013. In total, 388 (61%) patients were not in remission at the time of HSCT. With a median follow-up of 38.5 months, the probability of overall survival and the cumulative incidence of relapse at 3 years were 40 and 34%, respectively. In the multivariate analysis, two or more additional cytogenetic abnormalities and not being in remission at the time of HSCT were significantly associated with a higher overall mortality and relapse. Nevertheless, no significant impact on the outcome was observed in cases with one cytogenetic abnormality in addition to +8. Although more than 60% of the patients received HSCT when not in remission, allogeneic HSCT offered a curative option for adult patients with AML harboring +8.

    Full Text Available Objectives: Constitutive activation of the fms-like tyrosine kinase 3 (FLT3 receptor by internal tandem duplication (ITD of the juxtamembrane region has been described in patients with acute myeloid leukemia. FLT3/ITDs are present in about 20-30% of all acute myeloid leukemia cases. It has been shown that the mutation is correlated with worse prognosis. However, none of the previous studies investigated which FAB subtype is associated with higher percentage of FLT3/ITD, thus the reason for undertaking the current study.Methods: The prevalence and the potential prognostic impact of FLT3 mutations in 39 acute myeloid leukemia patients were analyzed by genomic polymerase chain reaction. Twelve samples with FLT3/ITDs and 27 acute myeloid leukemia samples without the mutations were compared with respect to clinical prognosis and FAB subtype. Results were correlated with cytogenetic data and the clinical response.Results: FLT3/ITD mutations were found in 31% of patients. FLT3/ITD was associated with similar clinical characteristics and was more prevalent in patients with normal karyotype (83%. Interestingly, half of the FLT3/ITD aberrations were found in patients with FAB M1 (50%, and fewer were found in patients with FAB M2 (8%, M4 (8%, and M5 (8%. Although less frequent in patients with cytogenetic aberrations, FLT3/ITDs were found in 17% of patients with t(15;17. Although the study was powered to 80%, patients with FLT3/ITD mutation did not show shorter complete remission duration or a higher relapse rate.Conclusion: The data confirm that FLT3/ITD mutations represent a common alteration in adult acute myeloid leukemia, mainly with normal karyotype (83% and de novo acute myeloid leukemia (75%, as compared to secondary acute myeloid leukemia (25% (p<0.001. It also showed that half of the M1-FAB subtype is FLT3/ITD positive. Therefore, FLT3/ITD is a therapeutic target, and thus inhibition of FLT3 tyrosine kinase activity may provide a new approach in

    Survival for adults and children with acute lymphoblastic leukaemia has risen substantially in recent years because use of improved risk-directed treatments and supportive care has widened. In nearly all developed countries, multidisciplinary panels of leukaemia experts have formulated clinical practice guidelines in which standard treatment approaches are recommended on the basis of current evidence. However, those guidelines do not take into account resource limitations in low-income countries, including financial and technical challenges. In Asia, huge disparities in economy and infrastructure exist between countries, and even among different regions in some large countries. At a consensus session held as part of the 2013 Asian Oncology Summit in Bangkok, Thailand, a panel of experts summarised recommendations for management of adult and paediatric acute lymphoblastic leukaemia. Strategies were developed for Asian countries on the basis of available financial, skill, and logistical resources and were stratified in a four-tier system according to the resources available in a particular country or region (basic, limited, enhanced, and maximum).

    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.

    Bacterial meningitis and meningococcal sepsis are rare conditions with high case fatality rates. Early recognition and prompt treatment saves lives. In 1999 the British Infection Society produced a consensus statement for the management of immunocompetent adults with meningitis and meningococcal sepsis. Since 1999 there have been many changes. We therefore set out to produce revised guidelines which provide a standardised evidence-based approach to the management of acute community acquired meningitis and meningococcal sepsis in adults. A working party consisting of infectious diseases physicians, neurologists, acute physicians, intensivists, microbiologists, public health experts and patient group representatives was formed. Key questions were identified and the literature reviewed. All recommendations were graded and agreed upon by the working party. The guidelines, which for the first time include viral meningitis, are written in accordance with the AGREE 2 tool and recommendations graded according to the GRADE system. Main changes from the original statement include the indications for pre-hospital antibiotics, timing of the lumbar puncture and the indications for neuroimaging. The list of investigations has been updated and more emphasis is placed on molecular diagnosis. Approaches to both antibiotic and steroid therapy have been revised. Several recommendations have been given regarding the follow-up of patients. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Objective: To compare the efficacy of cranial imaging techniques in adult patients with acute febrile encephalopathy. Methods: We enrolled one hundred and two patients presenting to the emergency with fever of shorter than 15-day duration and altered sensorium. All the patients were subjected to routine investigations, detailed cerebrospinal fluid analysis, computerized tomograms (Non contrast followed by contrast enhanced) and Magnetic resonance imaging of the brain. Final diagnosis was reached after considering the clinical, biochemical findings, imaging results and response to therapy. The positive yield of radiological investigations was compared against the final diagnosis. Results: The patients were divided into three groups. Of these patients, 48 had evidence of meningoencephalitis, 22 patients had pyogenic meningitis, and 20 were combined together in others group. In other 12 patients, a definitive diagnosis could not be made. Only 37% patients were detected to have abnormal computerized tomograms and the commonest abnormality was diffuse edema, which failed to point to an etiological diagnosis. Magnetic resonance imaging was abnormal in 62.75% cases and was able to suggest an etiological diagnosis in 100% cases of cerebral venous thrombosis, tubercular meningitis, 95% cases of meningoencephalitis and 45% with meningitis. Conclusions: Magnetic resonance imaging provides better information than computerized tomography in adult patients with acute febrile encephalopathy.

    Adult giant cell hepatitis (AGCH) is a rare event and only about 100 cases have been reported within the last 20 years. The AGCH has been observed in association with viral infection, drug reactions or autoimmune disorders but in many cases its etiology remains unclear. AGCH manifests clinically as severe form of hepatitis histologically characterized by diffuse giant cell transformation of hepatocytes. We report the case of a 39-yr-old man with acute community-acquired hepatitis without previous pathology of the liver. Laboratory data revealed slight hypergammaglobulinemia and high titer of anti-smooth-muscle antibody with negative serology of hepatotropic viruses and absence of other known causes of hepatitis. Preliminary diagnosis of autoimmune hepatitis was established, additionally confirmed by excellent clinical and biochemical improvement during corticosteroid treatment. A liver biopsy showed the typical findings of panlobular syncytial giant cell hepatitis and positive HCV-RNA both in serum and liver. The above verified the diagnosis of acute type C hepatitis manifested histologically as adult giant cell hepatitis. After three months of treatment we withdrew corticosteroids as spontaneous clearance of HCV occurred and the lack of autoantibodies in serum as well as significant improvement of liver histology was ascertained. Within 30 months of the follow-up we have not observed biochemical and immunological abnormalities and control liver biopsy has shown no signs of hepatitis.

    The factors responsible for the conjunctivitis and iritis associated with acute ocular infection and post enteric inflammatory disease are not fully known. The pro-inflammatory activity of unilateral topical application of muramyl dipeptide (MDP; the smallest bio-active Gram-positive and Gram-negative bacterial cell wall component) was investigated in adult rabbits. The resultant bilateral conjunctivitis/iritis and pyogenic responses were characterized. Bilateral symptoms were graded by slit lamp examinations; tear fluid, Schirmer tests (tear production), blood and aqueous humor (AH) samples were obtained from MDP-treated and untreated rabbits. MDP concentration, gamma-glutamyltranspeptidase activity (GGT; key enzyme in glutathione recapture, xenobiotic detoxification, eicosanoid synthesis and neutrophil function), protein concentration, and tear cell density, cytology, and immunofluorescent antibody reactivity to GGT and calreticulin (CRT; MDP-binding protein) were determined. MDP was cleared from ipsilateral tears and serum by 6 h, but was undetected in mock-treated contralateral tears. Bilateral signs of acute transient pyogenic conjunctivitis, characterized by tearing, lid edema, conjunctival hyperemia, chemosis and leukocytic infiltrate with iritis (erythema and aqueous flare) were detected. Milder symptoms occurred in the mock-treated contralateral eyes. Bilateral symptoms, tear production, tear protein, GGT activity, and mucopurulent discharge (containing up to 2.5-5.0 × 10(6) cells/mL) were elevated 4-8 h post MDP and resolved to near pre-treatment levels by 24 h. Tear GGT activity and protein levels were higher in MDP-treated and mock-treated contralateral eyes than in eyes of untreated adult rabbits (p's iritis and tear GGT activity, but ipsilateral GGT responses were lower. The results suggest unilateral topical MDP application to adult rabbit eyes induces a bilateral acute pyogenic conjunctivitis/iritis (PCI) characterized by increased vascular

    Adult patients with mixed phenotype acute leukemia (MPAL) have a poor prognosis, and the therapeutic role of allogeneic stem cell transplantation (allo-SCT) for MPAL remains to be elucidated. Thus, we retrospectively assessed the efficacy of allo-SCT for MPAL. Eighteen patients with MPAL were identified from the transplant outcome database of Kanto Study Group for Cell Therapy (KSGCT). We also selected 215 patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) as control cohorts using an optimal matching method. The 5-yr overall survival (OS) rate of patients with MPAL was 48.1%, and patients in remission at the time of transplant showed significantly better survival than those not in remission (5-yr OS: 71.8% vs. 0%, P = 0.001). No significant differences were seen in OS when stratifying patients according to immunophenotype, cytogenetic abnormalities, or the type of induction therapy. The 5-yr OS rate of patients with MPAL was not significantly different compared with AML control patients (48.1% vs. 48.1%; P = 0.855) or ALL control patients (48.1% vs. 37.8%; P = 0.426). These results suggested that allo-SCT is an effective treatment for MPAL, especially early in the disease course, and innovative transplant approaches are warranted to improve the transplant outcome of patients with MPAL who are not in remission. © 2015 John Wiley & Sons A/S.

    Long non-coding ribonucleic acids (RNAs) are a novel class of RNA molecules, which are increasingly recognized as important molecular players in solid and hematologic malignancies. Herein we investigated whether long non-coding RNA expression is associated with clinical and molecular features, as well as outcome of younger adults (aged <60 years) with de novo cytogenetically normal acute myeloid leukemia. Whole transcriptome profiling was performed in a training (n=263) and a validation set (n=114). Using the training set, we identified 24 long non-coding RNAs associated with event-free survival. Linear combination of the weighted expression values of these transcripts yielded a prognostic score. In the validation set, patients with high scores had shorter disease-free (P<0.001), overall (P=0.002) and event-free survival (P<0.001) than patients with low scores. In multivariable analyses, long non-coding RNA score status was an independent prognostic marker for disease-free (P=0.01) and event-free survival (P=0.002), and showed a trend for overall survival (P=0.06). Among multiple molecular alterations tested, which are prognostic in cytogenetically normal acute myeloid leukemia, only double CEBPA mutations, NPM1 mutations and FLT3-ITD associated with distinct long non-coding RNA signatures. Correlation of the long non-coding RNA scores with messenger RNA and microRNA expression identified enrichment of genes involved in lymphocyte/leukocyte activation, inflammation and apoptosis in patients with high scores. We conclude that long non-coding RNA profiling provides meaningful prognostic information in younger adults with cytogenetically normal acute myeloid leukemia. In addition, expression of prognostic long non-coding RNAs associates with oncogenic molecular pathways in this disease. clinicaltrials.gov Identifier: 00048958 (CALGB-8461), 00899223 (CALGB-9665), and 00900224 (CALGB-20202).

    Full Text Available Abstract Background Platelet transfusion is universally employed in acute leukemia. Platelet concentrate supernatants contain high concentrations of biologic mediators that might impair immunity. We investigated whether washed platelet and red cell transfusions could improve clinical outcomes in adult patients with acute leukemia. Methods A pilot randomized trial of washed, leukoreduced ABO identical transfusions versus leukoreduced ABO identical transfusions was conducted in 43 adult patients with acute myeloid or lymphoid leukemia during 1991–94. Primary endpoints to be evaluated were platelet transfusion refractoriness, infectious and bleeding complications and overall survival. Results There were no significant differences in infectious or major bleeding complications and only one patient required HLA matched platelet transfusions. Minor bleeding was more frequent in the washed, leukoreduced arm of the study. Confirmed transfusion reactions were more frequent in the leukoreduced arm of the study. Overall survival was superior in the washed arm of the study (40% versus 22% at 5 years, but this difference was not statistically significant (p = 0.36. A planned subset analysis of those ≤50 years of age found that those in the washed, leukoreduced arm (n = 12 had a 75% survival at five years compared with 30% in the leukoreduced arm (n = 10 (p = 0.037 Conclusion This study provides the first evidence concerning the safety and efficacy of washed platelets, and also raises the possibility of improved survival. We speculate that transfusion of stored red cell and platelet supernatant may compromise treatment, particularly in younger patients with curable disease. Larger trials will be needed to assess this hypothesis.

    Presepsin (sCD14-ST) is an emerging biomarker for infection. We hypothesized that presepsin could specifically increase during acute pyelonephritis and correlate with severity. We compared presepsin values in patients with acute pyelonephritis and controls, and we assessed its capacity to predict bacteraemia and admission in patients. In 312 patients with acute pyelonephritis (median age 33years), presepsin concentrations were higher than in controls (476 vs 200ng/L, ppyelonephritis patients with bacteraemia (614 vs. 461ng/L, p,=0.001) and in those requiring admission (614ng/L vs. 320ng/L, ppyelonephritis. However, it presents mild performance to predict bacteraemia and the need for admission, and offers no advantage as compared to CRP and PCT. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Background: Administering extracorporeal membrane oxygenation (ECMO to critically ill patients with acute respiratory distress syndrome has substantially increased over the last decade, however administering ECMO to patients with hematologic malignancies may carry a particularly high risk. Here, we report the clinical outcomes of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO. Methods: We performed a retrospective review of the medical records of patients with hematologic malignancies and severe acute respiratory failure who were treated with ECMO at the medical intensive care unit of a tertiary referral hospital between March 2010 and April 2015. Results: A total of 15 patients (9 men; median age 45 years with hematologic malignancies and severe acute respiratory failure received ECMO therapy during the study period. The median values of the Acute Physiology and Chronic Health Evaluation II score, Murray Lung Injury Score, and Respiratory Extracorporeal Membrane Oxygenation Survival Prediction Score were 29, 3.3, and -2, respectively. Seven patients received venovenous ECMO, whereas 8 patients received venoarterial ECMO. The median ECMO duration was 2 days. Successful weaning of ECMO was achieved in 3 patients. Hemorrhage complications developed in 4 patients (1 pulmonary hemorrhage, 1 intracranial hemorrhage, and 2 cases of gastrointestinal bleeding. The longest period of patient survival was 59 days after ECMO initiation. No significant differences in survival were noted between venovenous and venoarterial ECMO groups (10.0 vs. 10.5 days; p = 0.56. Conclusions: Patients with hematologic malignancies and severe acute respiratory failure demonstrate poor outcomes after ECMO treatment. Careful and appropriate selection of candidates for ECMO in these patients is necessary.

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

    Acute cough is a common problem in general practice and is often caused by a self-limiting, viral infection. Nonetheless, antibiotics are often prescribed in this situation, which may lead to unnecessary side effects and, even worse, the development of antibiotic resistant microorganisms worldwide. This study assessed the role of point-of-care C-reactive protein (CRP) testing and other predictors of antibiotic prescription in patients who present with acute cough in general practice. Patient characteristics, symptoms, signs, and laboratory and X-ray findings from 348 patients presenting to 39 general practitioners with acute cough, as well as the GPs themselves, were recorded by fourth-year medical students during their three-week clerkships in general practice. Patient and clinician characteristics of those prescribed and not-prescribed antibiotics were compared using a mixed-effects model. Of 315 patients included in the study, 22% were prescribed antibiotics. The two groups of patients, those prescribed antibiotics and those treated symptomatically, differed significantly in age, demand for antibiotics, days of cough, rhinitis, lung auscultation, haemoglobin level, white blood cell count, CRP level and the GP's license to self-dispense antibiotics. After regression analysis, only the CRP level, the white blood cell count and the duration of the symptoms were statistically significant predictors of antibiotic prescription. The antibiotic prescription rate of 22% in adult patients with acute cough in the Swiss primary care setting is low compared to other countries. GPs appear to use point-of-care CRP testing in addition to the duration of clinical symptoms to help them decide whether or not to prescribe antibiotics.

    Activation of the hypothalamic-pituitary-adrenal (HPA) axis is important for maintenance of homeostasis during stress. Recent studies have shown a connection between the HPA axis and adipose tissue. The present study investigated the effect of acute heterotypic stress on plasma levels of adrenocorticotropic hormone (ACTH), corticosterone (CORT), leptin, and ghrelin in adult male rats with respect to neonatal maternal social and physical stressors. Thirty rat mothers and sixty of their male progeny were used. Pups were divided into three groups: unstressed control (C), stressed by maternal social stressor (S), stressed by maternal social and physical stressors (SW). Levels of hormones were measured in adult male progeny following an acute swimming stress (10 min) or no stress. ELISA immunoassay was used to measured hormones. The ACTH and CORT levels were significantly increased in all groups of adult progeny after acute stress; however, CORT levels were significantly lower in both neonatally stressed groups compared to controls. After acute stress, plasma leptin levels were decreased in the C and SW groups but increased in the S group. The data suggest that long-term neonatal stressors lead to lower sensitivity of ACTH receptors in the adrenal cortex, which could be a sign of stress adaptation in adulthood. Acute stress in adult male rats changes plasma levels of leptin differently relative to social or physical neonatal stressors.

    The availability of alternative sources of stem cells including most recently T-replete haploidentical marrow or peripheral blood, and the increasing use of reduced-intensity conditioning (RIC), renders feasible an allogeneic transplant to almost all patients with acute leukemia up to 70 years of age. Autologous stem cell transplantation (ASCT) for consolidation of complete remission (CR), however, offers in some circumstances an alternative option. Although associated with a higher relapse rate, autologous transplant benefits from a lower non-relapse mortality, the absence of graft-versus-host disease (GVHD), and a better quality of life for long-term survivors. The recent use of intravenous busulfan (IVBU) with high-dose melphalan, better monitoring of minimal residual disease (MRD), and maintenance therapy post autografting bring new interest. Few retrospective studies compared the outcome following alternative donor versus autologous transplants for remission consolidation. Genoidentical and phenoidentical allogeneic stem cell transplantations are undisputed gold standards, but there are no data showing the superiority of alternative allogeneic donor over autologous transplantation, at the time of undetectable MRD, in patients with good- and intermediate-1 risk acute myelocytic leukemia (AML) in first complete remission (CR1), acute promyelocytic leukemia in second complete remission (CR2), and Philadelphia chromosome-positive (Ph(+)) acute lymphocytic leukemia (ALL).

    The effects of acute aerobic exercise on cognitive functions in humans have been the subject of much investigation; however, these studies are limited by several factors, including a lack of randomized controlled designs, focus on only a single cognitive function, and testing during or shortly after exercise. Using a randomized controlled design, the present study asked how a single bout of aerobic exercise affects a range of frontal- and medial temporal lobe-dependent cognitive functions and how long these effects last. We randomly assigned 85 subjects to either a vigorous intensity acute aerobic exercise group or a video watching control group. All subjects completed a battery of cognitive tasks both before and 30, 60, 90, or 120 min after the intervention. This battery included the Hopkins Verbal Learning Test-Revised, the Modified Benton Visual Retention Test, the Stroop Color and Word Test, the Symbol Digit Modalities Test, the Digit Span Test, the Trail Making Test, and the Controlled Oral Word Association Test. Based on these measures, composite scores were formed to independently assess prefrontal cortex- and hippocampal-dependent cognition. A three-way mixed Analysis of Variance was used to determine whether differences existed between groups in the change in cognitive function from pre- to post-intervention testing. Acute exercise improved prefrontal cortex- but not hippocampal-dependent functioning, with no differences found between delay groups. Vigorous acute aerobic exercise has beneficial effects on prefrontal cortex-dependent cognition and these effects can last for up to 2 hr after exercise.

    Conclusion: In summary, CD117 is a relatively frequently expressed myeloid marker contrary to earlier reports which describes its rare expression. Pediatric and adult ALL cases with low blast count and CD34 positivity are more likely to express aberrant myeloid markers. Current study also supports that myeloid antigen expression in both adult and pediatric ALL is not associated with adverse presenting clinical and biological features.

    Full Text Available Abstract Background Human bocavirus (HBoV is a newly discovered parvovirus associated with acute respiratory tract illness (ARTI and gastrointestinal illness. Our study is the first to analyze the characteristics of HBoV-positive samples from ARTI patients with a wide age distribution from Guangzhou, southern China. Methods Throat swabs (n=2811 were collected and analyzed from children and adults with ARTI over a 13-month period. The HBoV complete genome from a 60 year-old female patient isolate was also determined. Results HBoV DNA was detected in 65/2811 (2.3% samples, of which 61/1797 were from children (Mycoplasma pneumoniae had the highest frequency of 16.9% (11/65. Upper and lower respiratory tract illness were common symptoms, with 19/65 (29.2% patients diagnosed with pneumonia by chest radiography. All four adult patients had systemic influenza-like symptoms. Phylogenetic analysis of the complete genome revealed a close relationship with other HBoVs, and a more distant relationship with HBoV2 and HBoV3. Conclusions HBoV was detected from children and adults with ARTI from Guangzhou, southern China. Elderly people were also susceptive to HBoV. A single lineage of HBoV was detected among a wide age distribution of patients with ARTI.

    Patients with acute lymphoblastic leukaemia (ALL) after cytotoxic chemotherapy or haematopoietic stem cell transplantation (HSCT) are at risk for life-threatening invasive fungal disease (IFD). The aim was to evaluate the characteristics, antifungal therapy and outcome of adult patients with ALL after chemotherapy or HSCT receiving caspofungin empirically in a clinical setting. Retrospective chart reviews were conducted at nine large tertiary care centres in Germany. Adult patients with ALL treated empirically with caspofungin according to the product label between 2006 and 2012 were eligible. Data were extracted as case reports. In total, 25 patients (12 males, 13 females; median age 37 years; 19 with B-ALL, 6 with T-ALL) with 28 treatment episodes because of suspected IFD (18 episodes after chemotherapy, 10 episodes after allogeneic HSCT) were included in the analysis. Empirical caspofungin therapy (median duration: 19 days, range 1-105 days) was given as first-line monotherapy in 20 (71.4%), second-line monotherapy in five (17.9%) and combination therapy in three (10.7%) episodes respectively. Therapy rated successful according to the physician's overall assessment (inflammatory parameters, clinical symptoms): 20 (95%) of 21 evaluable episodes with therapy duration of at least 8 days. Empirical caspofungin appears to be an effective therapeutic option in critically ill adult ALL patients with suspected IFD in clinical practice.

    Fifty-four percent of adults with acute lymphoblastic leukemia (ALL) who entered the LALA-94 trial experienced a first relapse. We examined the outcome of these 421 adult patients. One hundred and eighty-seven patients (44%) achieved a second complete remission (CR). The median disease-free survival (DFS) was 5.2 months with a 5-year DFS at 12%. Factors predicting a better outcome after relapse were any transplant performed in second CR (P1 year (P=0.04) and platelet level >100 x 10(9)/l at relapse (P=0.04). Risk groups defined at diagnosis and treatment received in first CR did not influence the outcome after relapse. The best results were obtained in a subset of patients who were eligible for allogeneic stem cell transplantation (SCT). Geno-identical allogeneic SCT was performed in 55 patients, and 3 patients received donor lymphocyte infusions. Forty-four transplantations were performed from an unrelated donor (of which four were cord blood). We conclude that most adult patients with recurring ALL could not be rescued using current available therapies, although allogeneic SCT remains the best therapeutic option.

    Brief neonatal handling permanently alters hypothalamic-pituitary-adrenal axis function resulting in increased ability to cope with stress. Since stress is known to affect cognitive abilities, in the present study we investigated the effect of brief (15 min) handling on learning and memory in the Morris water maze, following exposure to an acute restraint stress either before training or recall. Exposure of non-handled rats to the acute stress prior to training resulted in quicker learning of the task, than in the absence of the stressor. When acute stress preceded acquisition, male handled rats showed an overall better learning performance, and both sexes of handled animals were less impaired in the subsequent memory trial, compared to the respective non-handled. In addition, the number of neurons immunoreactive for GR was higher in all areas of Ammon's horn of the handled rats during the recall. In contrast, the number of neurons immunoreactive for MR was higher in the CA1 and CA2 areas of the non-handled males. When the acute restraint stress was applied prior to the memory test, neonatal handling was not effective in preventing mnemonic impairment, as all animal groups showed a similar deficit in recall. In this case, no difference between handled and non-handled rats was observed in the number of GR positive neurons in the CA2 and CA3 hippocampal areas during the memory test. These results indicate that early experience interacts with sex and acute stress exposure in adulthood to affect performance in the water maze. Hippocampal corticosterone receptors may play a role in determining the final outcome.

  9. Acute stress differentially affects spatial configuration learning in high and low cortisol-responding healthy adults

    2013-05-01

    Full Text Available Background: Stress and stress hormones modulate memory formation in various ways that are relevant to our understanding of stress-related psychopathology, such as posttraumatic stress disorder (PTSD. Particular relevance is attributed to efficient memory formation sustained by the hippocampus and parahippocampus. This process is thought to reduce the occurrence of intrusions and flashbacks following trauma, but may be negatively affected by acute stress. Moreover, recent evidence suggests that the efficiency of visuo-spatial processing and learning based on the hippocampal area is related to PTSD symptoms. Objective: The current study investigated the effect of acute stress on spatial configuration learning using a spatial contextual cueing task (SCCT known to heavily rely on structures in the parahippocampus. Method: Acute stress was induced by subjecting participants (N = 34 to the Maastricht Acute Stress Test (MAST. Following a counterbalanced within-subject approach, the effects of stress and the ensuing hormonal (i.e., cortisol activity on subsequent SCCT performance were compared to SCCT performance following a no-stress control condition. Results: Acute stress did not impact SCCT learning overall, but opposing effects emerged for high versus low cortisol responders to the MAST. Learning scores following stress were reduced in low cortisol responders, while high cortisol-responding participants showed improved learning. Conclusions: The effects of stress on spatial configuration learning were moderated by the magnitude of endogenous cortisol secretion. These findings suggest a possible mechanism by which cortisol responses serve an adaptive function during stress and trauma, and this may prove to be a promising route for future research in this area.

  10. Rib plating of acute and sub-acute non-union rib fractures in an adult with cystic fibrosis: a case report.

    Rib fractures associated with osteoporosis have been reported to occur ten times more frequently in adults with cystic fibrosis. Fractures cause chest pain, and interfere with cough and sputum clearance leading to worsened lung function and acute exacerbations which are the two main contributors to early mortality in cystic fibrosis. Usual treatment involves analgesics and time for healing; however considerable pain and disability result due to constant re-injury from chronic repetitive cough. Recently, surgical plating of rib fractures has become commonplace in treating acute, traumatic chest injuries. We describe here successful surgical plating in a White cystic fibrosis patient with multiple, non-traumatic rib fractures. A-37-year old White male with cystic fibrosis was readmitted to Intermountain Medical Center for a pulmonary exacerbation. He had developed localized rib pain while coughing 2 months earlier, with worsening just prior to hospital admission in conjunction with a "pop" in the same location while bending over. A chest computerized tomography scan at admission demonstrated an acute 5th rib fracture and chronic non-united 6th and 7th right rib fractures. An epidural catheter was placed both for analgesia and to make secretion clearance possible in preparation for the surgery performed 2 days later. Under general anesthesia, he had open reduction and internal fixation of the right 5th, 6th and 7th rib fractures with a Synthes Matrix rib set. After several days of increased oxygen requirements, fever, fluid retention, and borderline vital signs, he stabilized. Numerical pain rating scores from his ribs were lower post-operatively and he was able to tolerate chest physical therapy and vigorous coughing. In our case report, rib plating with bone grafting improved rib pain and allowed healing of the fractures and recovery, although the immediate post-op period required close attention and care. We believe repair may be of benefit in selected cystic

    Data describing the epidemiology and management of viral acute diarrhea (AD) in adults are scant. The objective of this study was to identify the incidence, clinical characteristics, management and risk factors of winter viral AD in adults. The incidence of AD in adults during two consecutive winters (from December 2010 to April 2011 and from December 2011 to April 2012) was estimated from the French Sentinelles network. During these two winters, a subset of Sentinelles general practitioners (GPs) identified and included adult patients who presented with AD and who filled out a questionnaire and returned a stool specimen for virological examination. All stool specimens were tested for astrovirus, group A rotavirus, human enteric adenovirus, and norovirus of genogroup I and genogroup II. Age- and sex-matched controls were included to permit a case-control analysis with the aim of identifying risk factors for viral AD. During the studied winters, the average incidence of AD in adults was estimated to be 3,158 per 100,000 French adults (95% CI [2,321 - 3,997]). The most reported clinical signs were abdominal pain (91.1%), watery diarrhea (88.5%), and nausea (83.3%). GPs prescribed a treatment in 95% of the patients with AD, and 80% of the working patients with AD could not go to work. Stool examinations were positive for at least one enteric virus in 65% (95% CI [57 - 73]) of patients with AD with a predominance of noroviruses (49%). Having been in contact with a person who has suffered from AD in the last 7 days, whether within or outside the household, and having a job (or being a student) were risk factors significantly associated with acquiring viral AD. During the winter, AD of viral origin is a frequent disease in adults, and noroviruses are most often the cause. No preventable risk factor was identified other than contact with a person with AD. Thus, at the present time, reinforcement of education related to hand hygiene remains the only way to reduce the

    Full Text Available There is much interest in the mechanisms that regulate adult tissue homeostasis and their relationship to processes governing foetal development. Mice deleted for the Wilms' tumour gene, Wt1, lack kidneys, gonads, and spleen and die at mid-gestation due to defective coronary vasculature. Wt1 is vital for maintaining the mesenchymal-epithelial balance in these tissues and is required for the epithelial-to-mesenchyme transition (EMT that generates coronary vascular progenitors. Although Wt1 is only expressed in rare cell populations in adults including glomerular podocytes, 1% of bone marrow cells, and mesothelium, we hypothesised that this might be important for homeostasis of adult tissues; hence, we deleted the gene ubiquitously in young and adult mice. Within just a few days, the mice suffered glomerulosclerosis, atrophy of the exocrine pancreas and spleen, severe reduction in bone and fat, and failure of erythropoiesis. FACS and culture experiments showed that Wt1 has an intrinsic role in both haematopoietic and mesenchymal stem cell lineages and suggest that defects within these contribute to the phenotypes we observe. We propose that glomerulosclerosis arises in part through down regulation of nephrin, a known Wt1 target gene. Protein profiling in mutant serum showed that there was no systemic inflammatory or nutritional response in the mutant mice. However, there was a dramatic reduction in circulating IGF-1 levels, which is likely to contribute to the bone and fat phenotypes. The reduction of IGF-1 did not result from a decrease in circulating GH, and there is no apparent pathology of the pituitary and adrenal glands. These findings 1 suggest that Wt1 is a major regulator of the homeostasis of some adult tissues, through both local and systemic actions; 2 highlight the differences between foetal and adult tissue regulation; 3 point to the importance of adult mesenchyme in tissue turnover.

    Yawning is a familiar and phylogenetically widespread phenomenon, but no consensus exists regarding its functional significance. We tested the hypothesis that yawning communicates to others a transition from a state of physiological and/or psychological arousal (for example, due to action of a stressor) to a more relaxed state. This arousal reduction hypothesis predicts little yawning during arousal and more yawning (above baseline) during and after down-regulation of arousal. Experimental capture-restraint tests with wild adult Nazca boobies (Sula granti), a seabird, increased yawning frequency after release from restraint, but yawning was almost absent during tests. Natural maltreatment by non-parental adults also increased yawning by nestlings, but only after the maltreatment ended and the adult left. CORT (corticosterone) was a logical a priori element of the stress response affecting the stressor-yawning relationship under the arousal reduction hypothesis, and cannot be excluded as such for adults in capture-restraint tests but is apparently unimportant for nestlings being maltreated by adults. The arousal reduction hypothesis unites formerly disparate results on yawning: its socially contagious nature in some taxa, its clear pharmacological connection to the stress response, and its temporal linkage to transitions in arousal between consciousness and sleep.

    What is the central question of this study? Neurocognitive functions can be enhanced by acute aerobic exercise, which could be associated with changes in serum brain-derived neurotrophic factor (BDNF) concentrations. We aimed to explore acute exercise-induced changes in BDNF concentrations, neuropsychological and neurophysiological performances when individuals with different levels of cardiorespiratory fitness performed a cognitive task. What is the main finding and its importance? Only young adults with higher cardiorespiratory fitness could attain switching cost and neurophysiological benefits via acute aerobic exercise. The mechanisms might be fitness dependent. Although acute aerobic exercise could enhance serum BDNF concentrations, changes in peripheral BDNF concentrations could not be the potential factor involved in the beneficial effects on neurocognitive performance. This study investigated the effects of acute aerobic exercise on neuropsychological and neurophysiological performances in young adults with different cardiorespiratory fitness levels when performing a task-switching protocol and explored the potential associations between acute aerobic exercise-induced changes in serum brain-derived neurotrophic factor (BDNF) concentrations and various neurocognitive outcomes. Sixty young adults were categorized into one control group (i.e. non-exercise-intervention; n = 20) and two exercise-intervention (EI) groups [i.e. higher (EIH , n = 20) and lower (EIL , n = 20) cardiorespiratory fitness] according to their maximal oxygen consumption. At baseline and after either an acute bout of 30 min of moderate-intensity aerobic exercise or a control period, the neuropsychological and neurophysiological performances and serum BDNF concentrations were measured when the participants performed a task-switching protocol involving executive control and greater demands on working memory. The results revealed that although acute aerobic exercise decreased reaction

    Background Fever is common among patients seeking care in sub-Saharan Africa (sSA), but causes other than malaria are rarely diagnosed. We assessed dengue and chikungunya virus infections among young febrile adults evaluated for acute HIV infection (AHI) and malaria in coastal Kenya. Methods We tested plasma samples obtained in a cross-sectional study from febrile adult patients aged 18–35 years evaluated for AHI and malaria at urgent care seeking at seven health facilities in coastal Kenya in 2014–2015. Dengue virus (DENV) and chikungunya virus (CHIKV) were amplified using quantitative real-time reverse-transcription polymerase chain reaction. We conducted logistic regression analyses to determine independent predictors of dengue virus infection. Results 489 samples that were negative for both AHI and malaria were tested, of which 43 (8.8%, 95% confidence interval [CI]: 6.4–11.7) were positive for DENV infection. No participant was positive for CHIKV infection. DENV infections were associated with clinic visits in the rainy season (adjusted odds ratio (AOR) = 3.0, 95% CI: 1.3–6.5) and evaluation at a private health facility (AOR 5.2, 95% CI: 2.0–13.1) or research health facility (AOR = 25.6, 95% CI: 8.9–73.2) instead of a public health facility. Conclusion A high prevalence of DENV infections was found in febrile young adult patients evaluated for AHI. Our data suggests that DENV, along with AHI and malaria, should be considered in the differential diagnosis of the adult patient seeking care for fever in coastal Kenya. PMID:27942016

    2011-09-01

    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.

Four short-term, randomized, double-blind, placebo-controlled trials investigated the efficacy of paliperidone palmitate in acute exacerbation of schizophrenia. Paliperidone palmitate was also studied as a maintenance treatment to prevent or delay relapse in stable schizophrenia. In addition, paliperidone palmitate was compared to risperidone long-acting injection for noninferiority in three studies.Results: Paliperidone palmitate has been shown to be effective in reducing symptoms as measured by the Positive and Negative Syndrome Scale total scores in the four acute treatment studies. In the maintenance treatment studies, paliperidone palmitate was found to be more effective than placebo in preventing or delaying the time to first relapse in stable schizophrenia patients. In addition, paliperidone palmitate was shown to be noninferior to risperidone long-acting injection in two studies. It was shown to be reasonably well tolerated in all clinical trials. Acute treatment phase should be initiated with a dose of 234 mg on day one and 156 mg on day eight, followed by a recommended monthly maintenance dose of 39–234 mg based on efficacy and tolerability results from the clinical studies.Conclusion: Providing an optimal long-term treatment can be challenging. Paliperidone palmitate can be used as an acute treatment even in outpatient setting, and it has shown to be well tolerated by patients. Also, it does not require overlapping oral

    Acute lymphoblastic leukemia (ALL) is the most common of all childhood malignancies. Current remission rates approach 80%. Recurrent disease can present in a wide variety of ways. MR imaging plays a crucial role in the detection of disease relapse. Because other disorders can mimic recurrence of leukemia, it is important for the radiologist to judge recurrence from non-recurrence accurately in order to avoid unnecessary testing and emotional stress on the patient and family.

    Acute stress is increasingly recognized as a precipitant of acute myocardial infarction (AMI). However, the role of chronic stress in developing AMI is less clear. We have developed a method to measure cortisol in hair, which allows longitudinal assessment of cortisol levels prior to an acute event. We aimed to evaluate the hypothesis that chronic stress, as assessed by hair cortisol content, is associated with the development of AMI. A prospective case-control study included 56 patients admitted to hospital with AMI and 56 control patients, admitted to internal medicine wards for other indications. An enzyme immunoassay technique was used to measure cortisol in the most proximal 3 cm of hair, considered to represent the most recent 3 months of exposure. Median hair cortisol contents (range) were 295.3 (105.4-809.3)ng/g in AMI patients and 224.9 (76.58-949.9)ng/g in controls (p = 0.006, Mann-Whitney U-test). After controlling for other risk factors for AMI using multiple logistic regression, log-transformed hair cortisol content remained the strongest predictor (OR 17.4, 95% CI 2.15-140.5; p = 0.007). We demonstrated elevated hair cortisol concentrations in patients with AMI. This suggests that chronic stress, as assessed by increased hair cortisol in the 3 months prior to the event, may be a contributing factor for AMI.

    We report a case of allergic acute tubulointerstitial nephritis (TIN) induced by acetaminophen in a 48-year-old Japanese man with no past medical history. Two days after receiving the non-steroidal anti-inflammatory drug (NSAID) loxoprofen for left shoulder pain, he developed cold symptoms such as fever and sore throat. He then took a 300 mg dose of acetaminophen three times a day and a 100 mg dose of minocycline hydrochloride twice a day for 7 days. Because there was no improvement in his symptoms, he consulted a local clinic again, where blood tests revealed renal insufficiency, and he was, then, referred to our hospital for evaluation of kidney function. Renal biopsy revealed acute TIN, and Ga-67 scintigraphy showed diffuse uptake in bilateral kidneys. A drug-induced lymphocyte stimulation test (DLST) was positive for acetaminophen and negative for loxoprofen and minocycline. Based on these findings, we made a diagnosis of acetaminophen-induced TIN. We treated the patient with three courses of semi-pulse steroid therapy, after which his fever went down, and his serum creatinine level recovered from 2.09 to 1.43 mg/dL. Although we medical doctors think that therapeutic dose of acetaminophen retains high safety, it is important to keep in mind that acetaminophen can cause allergic acute TIN.

Evaluable cytogenetics or fluorescence in situ hybridization studies were available in 140 (70%) patients. Four karyotype categories (normal [n = 31, 22%], t(9;22)/BCR/ABL1 [n = 36, 26%], other unfavorable [-7, +8, or 11q23 rearrangement, n = 19, 13%], and miscellaneous [n = 54, 39%]) and the biologically and clinically relevant ALL ploidy subgroups were prospectively defined. Overall survival (OS) decreased significantly with increasing age (P = .009) and varied with karyotype category (P cytogenetics as the most important prognostic factor in adult ALL. This trial was registered at www.ClinicalTrials.gov as #NCT00002665.

    The therapeutic regimens for acute myelogenous leukemia in 2 different periods of time will be described with comparison of their results. A. 28 adults were treated with cytosine arabinoside and 6-thioguanine only. Thereby, 28% complete and 16% partial remissions were achieved. The mean duration of the complete remissions was 23 weeks. The mean survival time of the patients with complete remission amounted to 53 weeks B. 46% complete and 12% partial remissions were obtained in 37 patients treated with cytosine arabinoside and 6-thioguanine doubling the dosage of the above mentioned regimen followed by 3 cycles of TRAP (and COAP). Using a maintenance therapy with modified TRAP, COAP, and POMP cycles the complete remissions lasted 47 weeks at an average. The mean survival time of patients with complete remission was 87 weeks after start of treatment.

    Of 41 adults with a diagnosis of acute leukemia that were randomized for induction therapy in combination with methotrexate, 6-MP, vincristine and prednisone (POMP) versus a combination of cytosine arabinoside, cytoxan, vincristine and prednisone (COAP), 23 (56%) patients achieved a complete remission. During remission, patients received consolidation therapy with the three courses of remission induction regimen that they had not received initially. They then received daunomycin (three courses) and L-asparaginase and were then maintained for two years with their induction therapy. The median duration of survival for all patients was 40 weeks; the median duration of survival of those patients that responded to chemotherapy was 80 weeks. There was no significant difference between the two induction regimens with regard to complete remission more than four and one half years from diagnosis and two and one half years from discontinuation of all therapy.

    A 45-year-old hypertensive Japanese woman presented with epigastric pain on inspiration, fever, complete atrioventricular block and polyarthritis. Her antistreptolysin O levels were markedly elevated. A diagnosis of rheumatic fever was made according to the modified Jones criteria. She was prescribed loxoprofen sodium, which was partially effective for her extracardiac clinical symptoms. However, she had syncope due to complete atrioventricular block with asystole longer than 10 seconds. Consequently, we implanted a permanent pacemaker. Although we prescribed prednisolone, the efficacy of which was limited for the patient's conduction disturbance, the complete atrioventricular block persisted. In our systematic review of 12 similar cases, the duration of complete heart block was always transient and there was no case requiring a permanent pacemaker. We thus encountered a very rare case of adult-onset acute rheumatic fever with persistent complete atrioventricular block necessitating permanent pacemaker implantation.

    Full Text Available In contrast to FLT3 ITD mutations, in-frame deletions in the FLT3 gene have rarely been described in adult acute leukemia. We report two cases of AML with uncommon in-frame mutations in the juxtamembrane domain of the FLT3 gene: a 3-bp (c.1770_1774delCTACGinsGT; p.F590_V592delinsLF deletion/insertion and a 12-bp (c.1780_1791delTTCAGAGAATAT; p.F594_Y597del deletion. We verified by sequencing that the reading frame of the FLT3 gene was preserved and by cDNA analysis that the mRNA of the mutant allele was expressed in both cases. Given the recent development of FLT3 inhibitors, our findings may be of therapeutic value for AML patients harboring similar FLT3 mutations.

    Full Text Available Extramedullary relapse of acute lymphoblastic leukemia (ALL is rare and has been primarily reported in pediatric patients or hematopoietic stem cell transplant recipients. We report a case of a 62-year-old woman who presented with relapsed ALL involving her kidneys, pancreas, and bone marrow 2 years after completing chemotherapy with a standard ALL protocol. Unfortunately, her extramedullary disease progressed despite treatment. To the best of our knowledge, this is the first reported case of extramedullary relapse of B-cell ALL to the kidneys and pancreas occurring in an adult patient who had not previously undergone a hematopoietic stem cell transplant. A literature review of kidney and pancreatic extramedullary relapse in ALL is also included.

    Under pressure overload, initial adaptive hypertrophy of the heart is followed by cardiomyocyte elongation, reduced contractile force, and failure. The mechanisms governing the transition to failure are not fully understood. Pressure overload reduced cardiac myosin light chain kinase (cMLCK) by ∼80% within 1 week and persists. Knockdown of cMLCK in cardiomyocytes resulted in reduced cardiac contractility and sarcomere disorganization. Thus, we hypothesized that acute reduction of cMLCK may be causative for reduced contractility and cardiomyocyte remodelling during the transition from compensated to decompensated cardiac hypertrophy. To mimic acute cMLCK reduction in adult hearts, the floxed-Mylk3 gene that encodes cMLCK was inducibly ablated in Mylk3(flox/flox)/merCremer mice (Mylk3-KO), and compared with two control mice (Mylk3(flox/flox) and Mylk3(+/+)/merCremer) following tamoxifen injection (50 mg/kg/day, 2 consecutive days). In Mylk3-KO mice, reduction of cMLCK protein was evident by 4 days, with a decline to below the level of detection by 6 days. By 7 days, these mice exhibited heart failure, with reduction of fractional shortening compared with those in two control groups (19.8 vs. 28.0% and 27.7%). Severely convoluted cardiomyocytes with sarcomeric disorganization, wavy fibres, and cell death were demonstrated in Mylk3-KO mice. The cardiomyocytes were also unable to thicken adaptively to pressure overload. Our results, using a new mouse model mimicking an acute reduction of cMLCK, suggest that cMLCK plays a pivotal role in the transition from compensated to decompensated hypertrophy via sarcomeric disorganization.

    Bats are increasingly being recognized as important reservoir hosts for a large number of viruses, some of them can be highly virulent when they infect human and livestock animals. Among the new bat zoonotic viruses discovered in recent years, several reoviruses (respiratory enteric orphan viruses) were found to be able to cause acute respiratory infections in humans, which included Melaka and Kampar viruses discovered in Malaysia, all of them belong to the genus Orthoreovirus, family Reoviridae. In this report, we describe the isolation of a highly related virus from an adult patient who suffered acute respiratory illness in Malaysia. Although there was no direct evidence of bat origin, epidemiological study indicated the potential exposure of the patient to bats before the onset of disease. The current study further demonstrates that spillover events of different strains of related orthoreoviruses from bats to humans are occurring on a regular basis, which calls for more intensive and systematic surveillances to fully assess the true public health impact of these newly discovered bat-borne zoonotic reoviruses.

    CALM-AF10 (also known as PICALM-MLLT10) is the commonest fusion protein in T-cell acute lymphoblastic leukemia, but its prognostic impact remains unclear. Molecular screening at diagnosis identified CALM-AF10 in 30/431 (7%) patients with T-cell acute lymphoblastic leukemia aged 16 years and over and in 15/234 (6%) of those aged up to 15 years. Adult CALM-AF10-positive patients were predominantly (72%) negative for surface (s)CD3/T-cell receptor, whereas children were predominantly (67%) positive for T-cell receptor. Among 22 adult CALM-AF10-positive patients treated according to the LALA94/GRAALL03-05 protocols, the poor prognosis for event-free survival (P=0.0017) and overall survival (P=0.0014) was restricted to the 15 T-cell receptor-negative cases. Among CALM-AF10-positive, T-cell receptor-negative patients, 82% had an early T-cell precursor phenotype, reported to be of poor prognosis in pediatric T-cell acute lymphoblastic leukemia. Early T-cell precursor acute lymphoblastic leukemia corresponded to 22% of adult LALA94/GRAALL03-05 T-cell acute lymphoblastic leukemias, but had no prognostic impact per se. CALM-AF10 fusion within early T-cell precursor acute lymphoblastic leukemia (21%) did, however, identify a group with a poor prognosis with regards to event-free survival (P=0.04). CALM-AF10 therefore identifies a poor prognostic group within sCD3/T-cell receptor negative adult T-cell acute lymphoblastic leukemias and is over-represented within early T-cell precursor acute lymphoblastic leukemias, in which it identifies patients in whom treatment is likely to fail. Its prognosis and overlap with early T-cell precursor acute lymphoblastic leukemia in pediatric T-cell acute lymphoblastic leukemia merits analysis. The clinical trial GRAALL was registered at Clinical Trials.gov number NCT00327678. PMID:23831922

    A 61-year-old male was found to have a bilateral Bochdalek hernia on routine CT during admission for acute respiratory failure. The chest X-ray showed a left paracardiac mass having a diameter of 6 cm. This mass was initially considered as a mediastinal tumor. However, CT scan showed a bilateral large defect of the posteromedial portion of the diaphragm and mesenteric fat. 3D imaging was also useful for the stereographic perception of Bochdalek hernia. Although Bochdalek hernia is not rare, to our knowl-edge, this is the first case of Bochdalek hernia continued transverse colon observed by spiral CT 3D imaging.

    We examined time trend and age-period-cohort effects on acute myocardial infarction (AMI) mortality in Korean adults from 1988 to 2007. Annual AMI mortality data and population statistics from 1988 to 2007 were obtained from the STATISTICS KOREA website. Age adjusted mortality for four 5-yr calendar periods (1988-1992 to 2003-2007) was calculated by direct standardization using the Year 2000 WHO world standard population. A log-linear Poisson regression model was used to estimate age, period, and cohort effects on AMI mortality. In both genders, age-adjusted AMI mortality increased from period one (1988-1992) to period three (1998-2002) but decreased in period four (2003-2007). An exponential age effect was noted in both genders. The rate ratio of the cohort effect increased up to the 1943 birth cohort and decreased gradually thereafter, and the rate ratio of the period effect increased up to period three (1998-2002) and decreased thereafter. Our results suggest that AMI mortality in Korean adults has decreased since the period 1998-2002 and age, period, and cohort effects have influenced on AMI mortality.

    The survival rates for both adult and children with acute lymphoblastic leukaemia have improved substantially in recent years with wider use of improved risk-directed therapy and supportive care. In nearly all developed countries, clinical practice guidelines have been formulated by multidisciplinary panels of leukaemia experts, with the goal of providing recommendations on standard treatment approaches based on current evidence. However, those guidelines do not take into account resource limitations in low-income countries, including financial and technical challenges. In Asia, there are huge disparities in economy and infrastructure among the countries, and even among different regions in some large countries. This review summarizes the recommendations developed for Asian countries by a panel of adult and paediatric leukaemia therapists, based on the availability of financial, skill and logistical resources, at a consensus session held as part of the 2013 Asian Oncology Summit in Bangkok, Thailand. The management strategies described here are stratified by a four-tier system (basic, limited, enhanced and maximum) based on the resources available to a particular country or region. PMID:24176570

    While a number of studies have established that moderate doses of alcohol increase brain perfusion, the time course of such an increase as a function of breath alcohol concentration (BrAC) has not yet been investigated, and studies differ about regional effects. Using arterial spin labeling (ASL) magnetic resonance imaging, we investigated (1) the time course of the perfusion increase during a 15-minute linear increase of BrAC up to 0.6 g/kg followed by a steady exposure of 100 minutes, (2) the regional distribution, (3) a potential gender effect, and (4) the temporal stability of perfusion effects. In 48 young adults who participated in the Dresden longitudinal study on alcohol effects in young adults, we observed (1) a 7% increase of global perfusion as compared with placebo and that perfusion and BrAC are tightly coupled in time, (2) that the increase reaches significance in most regions of the brain, (3) that the effect is stronger in women than in men, and (4) that an acute tolerance effect is not observable on the time scale of 2 hours. Larger studies are needed to investigate the origin and the consequences of the effect, as well as the correlates of inter-subject variations.

    We aimed to investigate the association between the presenting clinical manifestations of bacterial meningitis and the duration of time elapsed before lumbar puncture and start of antibiotic treatment. Retrospective epidemiologic study using the clinical records in Barzilai Medical Center Emergency Department between 1988 and 1999. 97 patients, 72 children and 25 adults with ABM were identified. 30 of 97 (31%) were diagnosed by the primary physicians at primary care units. Acute meningitis was suspected by emergency department (ED) physicians in 51% of the referred patients. Patients with a scarce clinical picture at hospital arrival (those without fever, headache or nuchal rigidity) showed a trend toward a longer median delay until a diagnostic lumbar puncture was performed and antibiotic therapy was started (median of 14.7 h compared with 2.1 h for those with severe clinical picture) (ptreatment initiation (p>0.3). The interval before diagnosis of community acquired ABM in both children and adults is longer for those patients who present to the emergency department with an atypical clinical picture, mostly, without fever and without nuchal rigidity. Until bacterial meningitis can be effectively prevented, we can expect this life-threatening infection to continue to cause diagnostic and medical difficulties.

    Safety and efficacy data on pegylated asparaginase (PEG-ASP) in adult acute lymphoblastic leukaemia (ALL) induction regimens are limited. The UK National Cancer Research Institute UKALL14 trial NCT01085617 prospectively evaluated the tolerability of 1000 IU/m(2) PEG-ASP administered on days 4 and 18 as part of a five-drug induction regimen in adults aged 25-65 years with de novo ALL. Median age was 46.5 years. Sixteen of the 90 patients (median age 56 years) suffered treatment-related mortality during initial induction therapy. Eight of the 16 died of sepsis in combination with hepatotoxicity. Age and Philadelphia (Ph) status were independent variables predicting induction death >40 versus ⩽40 years, odds ratio (OR) 18.5 (2.02-169.0), P=0.01; Ph- versus Ph+ disease, OR 13.60 (3.52-52.36), P40 years. It proved extremely toxic in patients with Ph+ ALL, possibly owing to interaction with imatinib.

    Human rhinovirus (HRV) is an important causative agent of acute respiratory tract infections (ARTIs). The roles of specific HRV genotypes in patients suffering from ARTIs have not been well established. We recruited 147 adult inpatients with community-acquired pneumonia (CAP) and 291 adult outpatients with upper ARTIs (URTIs). Respiratory pathogens were screened via PCR assays. HRV was detected in 42 patients, with 35 species A, five B and two C. Seventeen genotypes were identified, and HRV-A21 ranked the highest (9/42, 21.4%). The HRV-A21-positive infections were detected in four patients with CAP and in five with URTIs, all without co-infections. The HRV-A21 genome sequenced in this study contained 12 novel coding polymorphisms in viral protein (VP) 1, VP2 EF loop, VP3 knob and 3D regions. The infections of HRV-A21 virus obtained in this study could not be neutralized by antiserum of HRV-A21 prototype strain (VR-1131), indicating remarkable antigenic variation. Metagenomic analysis showed the HRV-A21 reads were dominant in bronchoalveolar lavage fluid of the three HRV-A21-positive patients with severe CAP, in which two dead. Our results highlight an unexpected infection of genotype HRV-A21 in the clinic, indicating the necessity of precise genotyping and surveillance of HRVs to improve the clinical management of ARTIs.

    The role of serum cystatin C (Scys) for the detection of acute kidney injury (AKI) has not been fully discussed. This meta-analysis was aimed to investigate the overall diagnostic accuracy of Scys for AKI in adults, and further identify factors affecting its performance. Studies before Sept. 2016 were retrieved from PubMed, Embase, Web of Science and the Cochrane Library. A total of 30 prospective cohort studies (involving 4247 adults from 15 countries, 982 patients occurring AKI) were included. The revised Quality Assessment for Studies of Diagnostic Accuracy (QUADAS-2) tools demonstrated no significant bias had influenced the methodological quality of the included studies. Scys showed a high predictive power for all-cause AKI, that the area under the receiver operating characteristic curve was 0.89. The detailed assessment parameters, such as sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and diagnostic odds ratio for Scys were 0.82, 0.82, 4.6, 0.22 and 21, respectively. Although Scys could be slightly influenced by the following factors: settings, AKI diagnostic criteria, ethnicity, determination method, age and gender, these factors above did not reach statistically significance. In conclusion, Scys could be a vital promising marker to screen out AKI. PMID:28112204

    This study examined coincidence anticipation timing (CAT) performance at slow and fast stimulus speeds before, during, and after an acute bout of walking in adults aged 60-76 years. Results from a series of repeated measures ANOVAs indicated significant rest versus exercise × stimulus speed × time interactions for absolute and variable errors (both P = 0.0001) whereby absolute and variable error scores, when stimulus speed was slow, improved as the duration of exercise increased. When stimulus speed was fast there were significantly greater absolute and variable errors at 18 minutes of the walking bout. There was also greater error at 18 minutes during walking compared to rest. These results suggest that, in a task involving walking and CAT, stimulus speeds plays an important role; specifically walking (exercise) enhances CAT performance at slow stimulus speeds but reduces CAT performance at fast stimulus speeds. The implications are that in everyday situations, where events require dual-task responses to be made at different speeds, for example, walking on the pavement whilst avoiding a crowd, compared to crossing a busy road, an understanding of how different stimulus speeds influence dual-task performance is extremely important, particularly in the older adult population.

    Medulloblastoma (MB), the most common malignant tumor typically affecting children, occurs only exceptionally in adults. Multifocal presentation of this malignancy in adulthood is even much rarer—only four cases with favorable postoperative course have been reported, so far. The study illustrates a very rare rapid postoperative clinical deterioration due to diffuse cerebellar swelling (DCS) in an adult multifocal MB (MMB). To the best of their knowledge, authors for the first time performed genetic analysis of MMB and demonstrated expression patterns of selected markers that put the patient within the sonic hedgehog (SHH) molecular subgroup and at least partially explain her unsatisfactory clinical course. Herein, authors summarized the relevant literature concerning this issue with the aim to determine features that would facilitate diagnosis and therapy of such a scarce clinical entity.

    Hematopoeitic cell transplantation is established as a curative treatment for patients w acute myelogenous leukemia. Haploidentical family donor and umbilical cord blood(UCB) are alternative sources of stem cells for patients lacking a matched sibling or unrelated do-nor. The early challenges of transplant complications related to poor engraftment and graft-vs-host disease have been overcome with new strategies such as using 2 units and increased cell dose in UCB and T-cell deple-tion and post transplantation cyclophosphamide in hap-loidentical transplantation. The outcomes of alternative transplantation for acute leukemia were compared to other traditional graft sources. For patients lacking a matched sibling or unrelated donor, either strategy is a suitable option. The choice should rely mostly on the urgency of the transplantation and the available cell dose as well as the expertise available at the trans-plant center. This manuscript reviews the options of alternative donor transplantation and highlights recent advances in each of these promising transplantation options.

    Full Text Available Myocarditis consists of an inflammation of the cardiac muscle, definitively diagnosed by endomyocardial biopsy. The causal agents are primarily infectious: in developed countries, viruses appear to be the main cause, whereas in developing countries rheumatic carditis, Chagas disease, and HIV are frequent causes. Furthermore, myocarditis can be indirectly induced by an infectious agent and occurs following a latency period during which antibodies are created. Typically, myocarditis observed in rheumatic fever related to group A streptococcal (GAS infection occurs after 2- to 3-week period of latency. In other instances, myocarditis can occur within few days following a streptococcal infection; thus, it does not fit the criteria for rheumatic fever. Myocarditis classically presents as acute heart failure, and can also be manifested by tachyarrhythmia or chest pain. Likewise, GAS-related myocarditis reportedly mimics myocardial infarction (MI with typical chest pain, electrocardiograph changes, and troponin elevation. Here we describe a case of recurrent myocarditis, 5 years apart, with clinical presentation imitating an acute MI in an otherwise healthy 37-year-old man. Both episodes occurred 3 days after GAS pharyngitis and resolved quickly following medical treatment.

    Full Text Available BACKGROUND: Aberrant promoter DNA methylation has been shown to play a role in acute myeloid leukemia (AML pathophysiology. However, further studies to discuss the prognostic value and the relationship of the epigenetic signatures with defined genomic rearrangements in acute myeloid leukemia are required. METHODOLOGY/PRINCIPAL FINDINGS: We carried out high-throughput methylation profiling on 116 de novo AML cases and we validated the significant biomarkers in an independent cohort of 244 AML cases. Methylation signatures were associated with the presence of a specific cytogenetic status. In normal karyotype cases, aberrant methylation of the promoter of DBC1 was validated as a predictor of the disease-free and overall survival. Furthermore, DBC1 expression was significantly silenced in the aberrantly methylated samples. Patients with chromosome rearrangements showed distinct methylation signatures. To establish the role of fusion proteins in the epigenetic profiles, 20 additional samples of human hematopoietic stem/progenitor cells (HSPC transduced with common fusion genes were studied and compared with patient samples carrying the same rearrangements. The presence of MLL rearrangements in HSPC induced the methylation profile observed in the MLL-positive primary samples. In contrast, fusion genes such as AML1/ETO or CBFB/MYH11 failed to reproduce the epigenetic signature observed in the patients. CONCLUSIONS/SIGNIFICANCE: Our study provides a comprehensive epigenetic profiling of AML, identifies new clinical markers for cases with a normal karyotype, and reveals relevant biological information related to the role of fusion proteins on the methylation signature.

    A differentiation block with accumulation of immature myeloid cells characterizes acute myelogenous leukemia (AML). However, native AML cells often show some morphological signs of differentiation that allow a classification into different subsets, and further differentiation may be induced by exposure to various soluble mediators, e.g., all trans-retinoic acid (ATRA) and several cytokines. Combination therapy with ATRA and chemotherapy should now be regarded as the standard treatment for the acute promyelocytic leukemia variant of AML. Several agents can induce leukemic cell differentiation for other AML subtypes, although these effects differ between patients. Differentiation may then be associated with induction of apoptosis, and differentiation-inducing therapy may therefore become useful in combination with intensive chemotherapy to increase the susceptibility of AML blasts to drug-induced apoptosis. However, it should be emphasized that differentiation and apoptosis can occur as separate events with different regulation in AML cells, and future studies in AML should therefore focus on: A) the identification of new agents with more predictable effects on differentiation and apoptosis; B) the use of clinical and laboratory parameters to define new subsets of AML patients in which differentiation/apoptosis induction has a predictable and beneficial effect, and C) further characterization of how AML blast sensitivity to drug-induced apoptosis is modulated by differentiation induction.

    Introduction Poisoning is one of the most important health issues in the world. There is no exact statistic regarding the epidemiology of poisoning in Iran. The aim of this systematic review was to study the epidemiology of poisoning of adults in Iran. Methods All the published papers regarding the epidemiology and patterns of adult poisonings in different parts of Iran were reviewed in bibliographical databases, including SID, Iran Medex, Medlib, Magiran and Embase, Scopus, PubMed, and Google Scholar, without time limitation up to March 21, 2016. We searched for the terms poisoning, Iran, and epidemiology. After the final analysis, 38 articles that fulfilled all the required conditions were selected. Result In this article, we show that in most Iranian cities, except Ahvaz, pharmaceutical drugs, especially psychiatric pharmaceutical drugs, are the most common cause of poisoning in adults. In the Southwest region of Iran, poisoning due to envenomation is a very common. Although pesticide and opioid poisonings are less common, they are an important cause of death due to poisoning in Iran. Conclusion Pharmaceutical drugs are the most common cause of poisoning in most Iranian cities and it is recommended not to store pharmaceutical drugs at home and to set special rules regarding proper description of pharmaceutical drugs. More public health instruction is essential in the Southwest cities of Iran in order to reduce animal poisonings. PMID:27790337

    T-cell acute lymphoblastic leukemia (T-ALL) results from the collaboration of multiple genetic abnormalities in the transformation of T-cell progenitors. Plant homeodomain finger protein 6 (PHF6) has recently been established as a key tumor suppressor, which is mutated in T-ALL; however, the clinical significance of PHF6 mutations has not been fully determined in adult T-ALL. In the present study, amplification of the PHF6 exons was performed, followed by DNA sequencing to identify the genomic mutations and examine the expression of PHF6 in adult patients with T-ALL. The correlation between PHF6 mutations and clinical features was also analyzed using a χ(2) test, and between PHF6 mutations and survival curve using the Kaplan-Meier methods. PHF6 mutations were detected in 27.1% of the Chinese adults with T-ALL (16/59), 10 of which were found to be novel mutations. A significantly lower expression level of PHF6 was observed in T-ALL patients with PHF6 mutations compared with those without mutations. Of the observed mutations in PHF6, 6/16 were frame-shift mutations, indicating a PHF6 dysfunction in those patients. Of note, PHF6 mutations were found to be significantly associated with older age, lower hemoglobin levels, higher frequency of CD13 positivity and higher incidence of splenomegaly or lymphadenopathy. Furthermore, PHF6 mutations were found to be significantly correlated with Notch homolog 1, translocation-associated (Drosophila) (NOTCH1) mutations. The patients with T-ALL with co-existence of the two mutations had a significantly shorter event-free survival and a poor prognosis. The present results indicated that PHF6 is inactivated in adult T-ALL, due to its low expression and mutations. The present data indicated the synergistic effect of PHF6 and NOTCH1 mutations, as well as their co-existence, on the oncogenesis of adult T-ALL, and their potential as a prognostic marker for the disease.

  6. Long-term effects of an acute and systemic administration of LPS on adult neurogenesis and spatial memory

    Full Text Available The cognitive reserve is the capacity of the brain to maintain normal performance while exposed to insults or ageing. Increasing evidences point to a role for the interaction between inflammatory conditions and cognitive reserve status during Alzheimer's disease (AD progression. The production of new neurons along adult life can be considered as one of the components of the cognitive reserve. Interestingly, adult neurogenesis is decreased in mouse models of AD and following inflammatory processes. The aim of this work is to reveal the long-term impact of a systemic inflammatory event on memory and adult neurogenesis in wild type (WT and triple transgenic mouse model of AD (3xTg-AD.4 month-old mice were intraperitoneally injected once with saline or lipopolysaccharide (LPS and their performance on spatial memory analyzed with the Morris water maze (MWM test 7 weeks later. Our data showed that a single intraperitoneal injection with LPS has a long-term impact in the production of hippocampal neurons. Consistently, LPS-treated WT mice showed less doublecortin-positive neurons, less synaptic contacts in newborn neurons, and decreased dendritic volume and complexity. These surprising observations were accompanied with memory deficits. 3xTg-AD mice showed a decrease in new neurons in the dentate gyrus compatible with, although exacerbated, the pattern observed in WT LPS-treated mice. In 3xTg-AD mice, LPS injection did not significantly affected the production of new neurons but reduced their number of synaptic puncta and impaired memory performance, when compared to the observations made in saline-treated 3xTg-AD mice. These data indicate that LPS treatment induces a long-term impairment on hippocampal neurogenesis and memory. Our results show that acute neuroinflammatory events influence the production of new hippocampal neurons, affecting the cognitive reserve and leading to the development of memory deficits associated to Alzheimer's disease

    To compare the value of novel with conventional serum biomarkers in the prediction of acute kidney injury (AKI) in adult cardiac surgical patients according to preoperative renal function. Single-center, prospective observational study. Tertiary hospital. One hundred adult cardiac surgical patients. We measured concentrations of plasma neutrophil gelatinase-associated lipocalin (NGAL), and serum cystatin C, and creatinine and urea at baseline, on arrival in the intensive care unit (ICU) and at 24 hours postoperatively. We assessed such biomarkers in relation to the development of AKI (>50% increase in creatinine from baseline) and to a composite end point (need for renal replacement therapy and in-hospital mortality). We defined an area under the receiver operating characteristic curve of 0.60-0.69 as poor, 0.70-0.79 as fair, 0.80-0.89 as good, and 0.90-1.00 as excellent in terms of predictive value. On arrival in ICU, plasma NGAL and serum cystatin C were of good predictive value, but creatinine and urea were of poor predictive value. After exclusion of patients with preoperative renal impairment (estimated glomerular filtration rate fair value in such patients. At 24 hours postoperatively, all renal biomarkers were of good predictive value. On arrival in ICU, novel biomarkers were superior to conventional biomarkers (p value in the prediction of the composite end point. Early postoperative measurement of plasma NGAL was of good value in identifying patients who developed AKI after adult cardiac surgery. Plasma NGAL and serum cystatin C were superior to conventional biomarkers in the prediction of AKI and were also of prognostic value in this setting.

    Every acute myeloid leukemia (AML) patient asks: why me? But from the patients' perspective, there are no objective medical causes and no clear picture of AML. However, based on these missing medical answers, patients develop their own ideas about illness and treatment. These subjective theories of illness (STOI) are defined as the cognitive constructions ill people make regarding: (1) the nature of their disease; (2) its source; and (3) its treatment. STOI present a challenge for the physician-patient relationship. After the first interim staging, 12 patients with AML were interviewed. Case analyses were assigned to interindividual comparisons representing the predefined subject areas of STOI. Patients' vague subjective conceptions about the personalized etiology of AML resulted not only from health literacy deficits but also from their avoiding medical information to protect themselves from negative emotions. Through STOI, patients significantly co-determine the selection of (un-)conscious coping strategies with consequences for physician-patient communication.

    The pheromone drop test is a simple and robust behavioral assay to quantify acute avoidance of pheromones in C. elegans, and the suppression of avoidance by attractive pheromones. In the pheromone drop test, water-soluble C. elegans pheromones are individually applied to animals that are freely moving on a large plate. Upon encountering a repellent, each C. elegans animal may or may not try to escape by making a long reversal. The fraction of animals that make a long reversal response indicates the repulsiveness of a given pheromone to a specific genotype/strain of C. elegans. Performing the drop test in the presence of bacterial food enhances the avoidance response to pheromones. Attraction to pheromones can be assayed by the suppression of reversals to repulsive pheromones or by the suppression of the basal reversal rate to buffer.

    Therapeutic interpersonal relationships are the primary component of all health care interactions that facilitate the development of positive clinician–patient experiences. Therapeutic interpersonal relationships have the capacity to transform and enrich the patients’ experiences. Consequently, with an increasing necessity to focus on patient-centered care, it is imperative for health care professionals to therapeutically engage with patients to improve health-related outcomes. Studies were identified through an electronic search, using the PubMed, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO databases of peer-reviewed research, limited to the English language with search terms developed to reflect therapeutic interpersonal relationships between health care professionals and patients in the acute care setting. This study found that therapeutic listening, responding to patient emotions and unmet needs, and patient centeredness were key characteristics of strategies for improving therapeutic interpersonal relationships.

    Full Text Available Adverse experiences occurred in early life and especially during childhood and adolescence can have negative impact on behavior later in life and the quality of maternal care is considered a critical moment that can considerably influence the development and the stress responsiveness in offspring. This review will assess how the association between neonatal and adolescence stressful experiences such as maternal separation and social isolation, at weaning, may influence the stress responsiveness and brain plasticity in adult rats. Three hours of separation from the pups (3-14 postnatal days significantly increased frequencies of maternal arched-back nursing and licking-grooming by dams across the first 14 days postpartum and induced a long-lasting increase in their blood levels of corticosterone. Maternal separation, which per sedid not modified brain and plasma allopregnanolone and corticosterone levels in adult rats, significantly reduced social isolation-induced decrease of the levels of these hormones. Moreover, the enhancement of corticosterone and allopregnanolone levels induced by foot shock stress in socially isolated animals that were exposed to maternal separation was markedly reduced respect to that observed in socially isolated animals. Our results suggest that in rats a daily brief separation from the mother during the first weeks of life, which per se did not substantially alter adult function and reactivity of hypothalamic-pituitary-adrenal (HPA axis, elicited a significant protection versus the subsequent long-term stressful experience such that induced by social isolation from weaning. Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in NeonatologyGuest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

  12. Loss of extracellular superoxide dismutase leads to acute lung damage in the presence of ambient air: a potential mechanism underlying adult respiratory distress syndrome.

    The extracellular superoxide dismutase 3 (SOD3) is highly expressed in both blood vessels and lungs. In different models of pulmonary injury, SOD3 is reduced; however, it is unclear whether this contributes to lung injury. To study the role of acute SOD3 reduction in lung injury, the SOD3 gene was deleted in adult mice by using the Cre-Lox technology. Acute reduction of SOD3 led to a fivefold increase in lung superoxide, marked inflammatory cell infiltration, a threefold increase in the arterial-alveolar gradient, respiratory acidosis, histological changes similar to those observed in adult respiratory distress syndrome, and 85% mortality. Treatment with the SOD mimetic MnTBAP and intranasal administration of SOD-containing polyketal microparticles reduced mortality, prevented the histological alterations, and reduced lung superoxide levels. To understand how mice with the SOD3 embryonic deletion survived without lung injury, gene array analysis was performed. These data demonstrated the up-regulation of 37 genes and down-regulation of nine genes, including those involved in cell signaling, inflammation, and gene transcription in SOD3-/- mice compared with either mice with acute SOD3 reduction or wild-type controls. These studies show that SOD3 is essential for survival in the presence of ambient oxygen and that acute loss of this enzyme can lead to severe lung damage. Strategies either to prevent SOD3 inactivation or to augment its levels might prove useful in the treatment of acute lung injury.

    Rabbit Haemorrhagic Disease (RHD) is a lethal infection caused by calicivirus that kills 90% of the infected adult rabbits within 3 days. The calicivirus replicates in the liver and causes a fulminant hepatitis. Most studies on the pathology of RHD have been focused on the fulminant liver disease. This may not be the only mechanism in the pathogenesis of RHD: calicivirus infection may also induce leukopenia in the infected adult rabbits. We show now by flow cytometry analysis that the calicivirus induces an early decrease in B and T cells, in both spleen and liver. The depletion of B and T cells was associated with apoptosis labelled by annexin V. These changes occurred in rabbits before they showed enzymatic evidence of liver damage and persisted after liver transaminase values were very high. We conclude that depletion of lymphocytes caused by the calicivirus infection precedes or attends liver damage. The relative contribution of this lymphocyte depletion for the pathogenesis of the fatal calicivirus infection of rabbits remains to be investigated.

    Upper respiratory tract infections (URTI), including acute bronchitis, are the frequent health problems and the most common reason for acute cough in adults. Even though the infections are caused mainly by viruses, and their course is usually not complicated, febrifuges, i.a. mucokinetics, or antitussives are used in the treatment of URTI in order to improve the quality of life and safety of patients. To evaluate the efficacy and safety of Bronchosol® herbal syrup in comparison to ambroxol preparations in the treatment of acute bronchitis in adult patients. The Bronchosol®/2013 study was a non-interventional, prospective, open-label, observational study. Data from adult patients treated with Bronchosol® syrup for acute bronchitis were collected and compared with data from patients treated for the same condition with ambroxol preparations. The severity of bronchitis symptoms was evaluated with the BSS (Bronchitis Severity Score) scale, and patients'quality of life wasassessed with the VAS (Visual Analogue Scale) scale. Between visits patients conducted self-observations and filled out observation diaries. Moreover, the data on adverse events were collected. In 87.68% of patients the infections were cured. Most of patients considered the studied drugs to be the agent decreasing the duration of infection and its intensity. The percentage of patients who declared that they had a less intense cough than during earlier infections was higher in the group of patients treated with Bronchosol® syrup in comparison to ambroxol treated patients (60.22% vs. 45.03%). 91.94% of patients treated with Bronchosol® considered this syrup to be very safe; in the ambroxol group such a declaration was made by 76.61% of patients. Bronchosol® syrup is an efficient, well-tolerated, and safe drug. Its efficacy in the treatment of acute bronchitis symptoms in adult patients is similar to the efficacy of ambroxol preparations.

    Secondary myelodysplastic syndrome and acute myelogenous leukemia (sMDS/sAML) are the most serious secondary events occurring after immunosuppressive therapy in patients with aplastic anemia. Here we evaluate the outcome of hematopoietic stem cell transplantation (HSCT) in 17 children and young adults with sMDS/sAML after childhood aplastic anemia. The median interval between the diagnosis of aplastic anemia and the development of sMDS/sAML was 2.9 years (range, 1.2 to 13.0 years). At a median age of 13.1 years (range, 4.4 to 26.7 years), patients underwent HSCT with bone marrow (n = 6) or peripheral blood stem cell (n = 11) grafts from HLA-matched sibling donors (n = 2), mismatched family donors (n = 2), or unrelated donors (n = 13). Monosomy 7 was detected in 13 patients. The preparative regimen consisted of busulfan, cyclophosphamide, and melphalan in 11 patients and other agents in 6 patients. All patients achieved neutrophil engraftment. The cumulative incidence of grade II-IV acute graft-versus-host disease (GVHD) was 47%, and that of chronic GVHD was 70%. Relapse occurred in 1 patient. The major cause of death was transplant-related complication (n = 9). Overall survival and event-free survival at 5 years after HSCT were both 41%. In summary, this study indicates that HSCT is a curative therapy for some patients with sMDS/sAML after aplastic anemia. Future efforts should focus on reducing transplantation-related mortality.

    Guaifenesin (glyceryl guaiacolate ether [GGE]) has been studied as a cough suppressant and as an expectorant; however, published studies to date have failed to find a consistent benefit. An 8-day multi-center clinical trial was conducted to study the effect of two 600-mg extended-release GGE tablets twice daily for 1 week on cold symptoms, sputum volume, and properties in adolescents and adults with productive cough from an acute respiratory tract infection (RTI). The study enrolled 378 subjects (GGE, n = 188; and placebo, n = 190) who were otherwise healthy and had an RTI for up to 5 days before enrollment. Subjects suffered from at least 2 of 3 symptoms of cough, thickened mucus, and chest congestion. A total of 151 GGE and 144 control subjects completed the full protocol. Single-sputum samples were collected from each subject on days 1, 3, 4, and 8 of the study. The rheology and interfacial tension of sputum were measured, and 24-h collected samples from days 1 and 4 were analyzed for total volume and hydration. Symptoms in both the GGE and placebo groups improved to a similar degree over time. There were no significant differences between the GGE and placebo groups for sputum volume (P = .41), percent solids (P = .69), interfacial tension (P = .88), elasticity (P = .71), viscosity (P = .45), or mechanical impedance (P = .75). The recommended dose of GGE had no measurable effect on sputum volume or properties and is unlikely to be an expectorant or mucolytic when used to treat acute RTI.

    Adult patients with acute leukemia in need of a transplant but without a genoidentical donor are usually considered upfront for transplantation with stem cells from any other allogeneic source, rather than autologous stem cell transplantation. We used data from the European Society for Blood and Marrow Transplantation and performed a matched pair analysis on 188 T-cell-replete haploidentical and 356 autologous transplants done from January 2007 to December 2012, using age, diagnosis, disease status, cytogenetics, and interval from diagnosis to transplant as matching factors. "Haploidentical expert" centers were defined as having reported more than five haploidentical transplants for acute leukemia (median value for the study period). The median follow-up was 28 months. Multivariate analyses, including type of transplant categorized into three classes ("haploidentical regular", "haploidentical expert" and autologous), conditioning intensity (reduced intensity versus myeloablative conditioning) and the random effect taking into account associations related to matching, showed that non-relapse mortality was higher following haploidentical transplants in expert (HR: 4.7; P=0.00004) and regular (HR: 8.98; Ptransplants was lower in expert centers (HR:0.39; P=0.0003) but in regular centers was similar to that for autologous transplants. Leukemia-free survival and overall survival rates were higher following autologous transplantation than haploidentical transplants in regular centers (HR: 1.63; P=0.008 and HR: 2.31; P=0.0002 respectively) but similar to those following haploidentical transplants in expert centers. We conclude that autologous stem cell transplantation should presently be considered as a possible alternative to haploidentical transplantation in regular centers that have not developed a specific expert program.

    Hyperleukocytic acute myeloid leukaemia is considered to have a poor prognosis due to high early death rate secondary to leukostasis. Supportive treatments do not seem to have reduced early exitus in this subset of patients. Prognostic impact of hyperleukocytosis on outcome has been the object of few studies. Clinical characteristics and outcome of 45 consecutive adult patients with newly diagnosed acute myeloid leukaemia presenting to our institution with a white cell count (WBC) above 100 x 10(9)L(-1) were reviewed. The outcome of this subset of patients was compared with 200 patients with a leukocyte count lower than 100 x 10(9)L(-1) similarly treated in the same period. Eight hyperleukocytic patients (17%) died of intracranial haemorrhage or pulmonary failure due to leukostasis within the first 7 days of treatment. A significant association was found between complete response (CR) and absence of hyperleukocytosis, but if early deaths were removed from analysis the difference was no longer significant. Hyperleukocytosis also significantly reduces the overall survival (OS) but does not significantly influence the disease-free survival (DFS). We reviewed in literature studies in which the outcome of series of at least 10 patients with hyperleukocytosis were compared with that of patients with a leukocyte count lower than 100 x 10(9)L(-1). Our data were consistent with those of the literature regarding the rate of early mortality and causes of death. In most of the reviewed series hyperleukocytosis does not seem to influence the outcome of patients. Avoiding early death seems to be an important step in this subset of patients. New data about pathophysiology of leukostasis are needed.

    Abstract Rationale: The presence of the Philadelphia chromosome (Ph) in acute lymphoblastic leukemia (ALL) has been associated with a high risk of disease relapse and a poor prognosis. Allogeneic hematopoietic stem cell transplantation (HSCT) is an established treatment for adults with Ph-positive ALL, but relapse remains the primary cause of treatment failure, and is associated with an extremely poor prognosis. The emergence of resistance to tyrosine kinase inhibitors (TKIs) poses a challenge for patients with disease relapses after initial treatment with TKI-containing regimens. Patient concerns: Two patients with TKI-resistant recurrent Ph-positive ALL. Diagnoses: Ph-positive ALL. Interventions: Anti-CD19 CAR T-cell infusion. Outcomes: One patient's bone marrow blasts decreased significantly, and the other reached negative minimal residual disease (MRD). However, we first recorded the development of new-onset acute graft-versus-host disease (aGVHD) after anti-CD19 CAR T-cell infusion in a patient who received allogeneic HSCT. Our 2 case reports also demonstrate the efficacy of anti-CD19 CAR T-cell therapy in the treatment of TKI-resistant Ph-positive ALL. Lessons: Our report suggests that anti-CD19 CAR T-cell therapy may be a promising option for the treatment of relapsed Ph-positive ALL after conventional chemotherapy or allogeneic HSCT. However, caution is due given the possibility of the adverse effects of cytokine release syndrome (CRS)-induced aGVHD for patients receiving allogeneic HSCT. PMID:28002337

    Morphological alterations of the lung in respiratory distress syndrome of adults (ARDS) were analyzed in 10 cases with traumatic-and septic shock, laryngitis subglottica descendens and bronchopneumonia. For the better understanding of the pathomechanism of the disease in addition to the standard methods, first of all ultrastructural alterations were studied. Two phases of the morphologic alterations could be distinguished, the phase of the destruction and the phase of the repair. These two processes are not sharply distinguishable. Genesis of the characteristic histological alterations (damage to the epithelial and endothelial cells, formation of hyaline membranes, microcoagulation, proliferation of the type II pneumocytes and fibroblasts, fibrosis) is discussed, with regard to the data of the literature.

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

    A 9-yr-old castrated male dromedary camel (Camelus dromedarius) presented with lethargy and partial anorexia. A diagnostic examination revealed fever, and further workup revealed a neutrophilia, hyperfibrinogenemia, renal azotemia, and a rapid onset of a high Leptospira antibody titer during the acute clinical period (Grippotyphosa serovar). The camel responded clinically to antimicrobial treatment with ceftiofur crystalline free acid injections, but renal azotemia persisted, presumably secondary to chronic renal damage. Subsequent Leptospira polymerase chain reaction testing on urine samples obtained over the following 4 mo revealed no evidence of urinary shedding, so a persistent infection was unlikely. Although often mentioned as a potential cause of reproductive loss, well-documented case reports of clinical leptospirosis in camelids are very rare. In this case, native wildlife contamination of a small watering hole is suspected to have been the source of infection. In response to this experience, the camel and two conspecifics were prescribed a vaccination regimen using an inactivated pentavalent Leptospira vaccine licensed for cattle.

    Full Text Available Three cases of acute flaccid paralysis (AFP with preceding fever are described. One patient had a quadriparesis with a florid meningoencephalitic picture and the other two had asymmetric flaccid paralysis with fasciculations at the onset of illness. Magnetic resonance imaging in two cases showed prominent hyperintensitities in the spinal cord and brainstem with prominent involvement of the grey horn (polio-myelitis. Cerebrospinal fluid (CSF polymerase chain reaction was positive for West Nile virus (WNV in the index patient. All three cases had a positive WNV immunoglobulin M antibody in serum/CSF and significantly high titer of WNV neutralizing antibody in serum, clearly distinguishing the infection from other Flaviviridae such as Japanese encephalitis. WNV has been recognized in India for many decades; however, AFP has not been adequately described. WNV is a flavivirus that is spread by Culex mosquitoes while they take blood meals from humans and lineage 1 is capable of causing a devastating neuro-invasive disease with fatal consequences or severe morbidity. We describe the first three laboratory confirmed cases of WNV induced AFP from Kerala and briefly enumerate the salient features of this emerging threat.

    Choline is a dietary component and precursor of acetylcholine, a crucial neurotransmitter for memory-related brain functions. In two double-blind, placebo-controlled cross-over experiments, we investigated whether the food supplement choline bitartrate improved declarative memory and working memory in healthy, young students one to two hours after supplementation. In experiment 1, 28 participants performed a visuospatial working memory task. In experiment 2, 26 participants performed a declarative picture memorization task. In experiment 3, 40 participants performed a verbal working memory task in addition to the visuospatial working memory and declarative picture task. All tasks were conducted approximately 60 minutes after the ingestion of 2.0-2.5g of either choline bitartrate or placebo. We found that choline did not significantly enhance memory performance during any of the tasks. The null hypothesis that choline does not improve memory performance as compared to placebo was strongly supported by Bayesian statistics. These results are in contrast with animal studies suggesting that choline supplementation boosts memory performance and learning. We conclude that choline likely has no acute effects on cholinergic memory functions in healthy human participants.

    Aim To investigate the determinants of adherence to amoxicillin in patients with acute lower respiratory tract infection. Materials and methods Three European data sets were used. Adherence data were collected using self-reported diaries. Candidate determinants included factors relating to patient, condition, therapy, health care system/provider, and the study in which the patient participated. Logistic and Cox regression models were used to investigate the determinants of initiation, implementation, and discontinuation of amoxicillin. Results Although initiation differed across samples, implementation and discontinuation were similar. Determinants of initiation were days waited before consulting, duration of prescription, and being in a country where a doctor-issued sick certificate is required for being off work for <7 days. Implementation was higher for older participants or those with abnormal auscultation. Implementation was lower for those prescribed longer courses of amoxicillin (≥8 days). Time from initiation to discontinuation was longer for longer prescriptions and shorter for those from countries where single-handed practices were widespread. Conclusion Nonadherence to amoxicillin was largely driven by noninitiation. Differing sets of determinants were found for initiation, implementation, and discontinuation. There is a need to further understand the reasons for these determinants, the impact of poor adherence to antibiotics on outcomes, and to develop interventions to improve antibiotic use when prescribed.

    Introduction. A number of viruses have been implicated in viral myocarditis; however, there has been no previous report of human metapneumovirus (hMPV) causing this condition. Discovered in 2001, hMPV is typically associated with upper respiratory illness, mainly affecting children. Case Presentation. We report the case of a 25-year-old man with acute systolic heart failure from viral myocarditis secondary to the hMPV. The patient was initially admitted to the general medical ward but developed increasing oxygen requirements resulting in transfer to the cardiac intensive care unit. Cardiac magnetic resonance imaging was used to help confirm the diagnosis. He was treated with intravenous diuretics, and afterload and preload agents, and he was subsequently discharged home after seven days of hospitalization. Discussion. hMPV is typically a respiratory pathogen; however, it was associated with in myocarditis in our patient. Due to the recent ability to detect this virus, we may see more cases of this, particularly during peak months of infection. Conclusion. This is the first case description of myocarditis associated with hMPV infection.

  10. Molecular prognostic markers for adult acute myeloid leukemia with normal cytogenetics

    2009-06-01

    Full Text Available Abstract Acute myeloid leukemia (AML is a heterogenous disorder that results from a block in the differentiation of hematopoietic progenitor cells along with uncontrolled proliferation. In approximately 60% of cases, specific recurrent chromosomal aberrations can be identified by modern cytogenetic techniques. This cytogenetic information is the single most important tool to classify patients at their initial diagnosis into three prognostic categories: favorable, intermediate, and poor risk. Currently, favorable risk AML patients are usually treated with contemporary chemotherapy while poor risk AML patients receive allogeneic stem cell transplantation if suitable stem cell donors exist. The largest subgroup of AML patients (~40% have no identifiable cytogenetic abnormalities and are classified as intermediate risk. The optimal therapeutic strategies for these patients are still largely unclear. Recently, it is becoming increasingly evident that it is possible to identify a subgroup of poorer risk patients among those with normal cytogenic AML (NC-AML. Molecular risk stratification for NC-AML patients may be possible due to mutations of NPM1, FLT3, MLL, and CEBPα as well as alterations in expression levels of BAALC, MN1, ERG, and AF1q. Further prospective studies are needed to confirm if poorer risk NC-AML patients have improved clinical outcomes after more aggressive therapy.

    The tyrosine kinase inhibitor (TKI) imatinib has become an integral part of front-line therapy for Philadelphia chromosome-positive acute lymphoblastic leukaemia, with remission rates exceeding 90% irrespective of whether imatinib is given alone or combined with chemotherapy. Treatment outcome with imatinib-based regimens has improved compared with historic controls, but most patients who do not undergo allogeneic stem cell transplantation (SCT) eventually relapse. Second-generation TKI, e.g. dasatinib and nilotinib, show activity against most of the bcr-abl tyrosine kinase domain mutations involved in acquired imatinib resistance, but clinical benefit is generally short lived. Accordingly, SCT in first complete response is considered to be the best curative option. Strategies to improve outcome in patients ineligible for transplantation as well as after SCT include front-line treatment with more effective TKI to increase molecular response rates. Following SCT, the pre-emptive use of imatinib appears to reduce the relapse rate. Novel immunotherapeutic interventions and combinations of TKI are also being explored.

    Mercury intoxication may present in a wide range of clinical forms from a simple disease to fatal poisoning. This article presents a case of acute mercury poisoning, a rare condition that presents challenges for diagnosis with fever of unknown origin. A 52-year-old Caucasian woman was admitted to the hospital with high fever, sore throat, a rash over her entire body, itching, nausea, and extensive muscle pain. She had cervical, bilateral axillary and mediastinal lymphadenopathies. We learned that her son and husband had similar symptoms. After excluding infectious pathologies, autoimmune diseases and malignancy were investigated. Multiple organs of our patient were involved and her fever persisted at the fourth week of admission. A repeat medical history elicited that her son had brought mercury home from school and put it on the hot stove, and the family had been exposed to the fumes for a long period of time. Our patient's serum and urine mercury levels were high. She was diagnosed with mercury poisoning and treated accordingly. Mercury vapor is a colourless and odorless substance. Therefore, patients with various unexplained symptoms and clinical conditions should be questioned about possible exposure to mercury.

    Full Text Available Intracranial large artery atherosclerosis is an important cause of stroke worldwide. Previous studies have shown that it is found more commonly in Asians. However, studies of intracranial stenosis in Indonesian stroke patients have been very few in number. The aim of this cross-sectional study was to determine the frequency and risk factors of intracranial stenosis in acute ischemic stroke. The data were obtained from 234 consecutive patients in the transcranial doppler (TCD registry. Documentation of risk factors was performed systematically and for TCD sonography TD-DOP 9000 equipment with a 2-MHz probe was used for the examination of the intracranial circulation. The criteria of middle cerebral artery (MCA stenosis used in this study were a peak systolic velocity (PSV >140 cm/s or mean systolic velocity (MSV >80 cm/s. For stenosis of the posterior circulation the criteria were PSV > 90 cm/s or MSV >60 cm/s. The data were obtained from 234 patients, and complete examinations were performed in 182 patients (77.7%. Ischemic stroke is the most common indication for performing TCD sonography. Stenosis was present in 38% of cases, with stenosis iof the anterior circulation being the more common. The most frequent risk factors were hypertension, dyslipidemia, and diabetes. Intracranial stenosis is common in stroke patients, in whom the risk factors are hypertension and diabetes.

    Traumatic acute subdural hematoma (ASDH) is a major clinical entity in traumatic brain injury (TBI). It acts as a space occupying lesion to increase intracranial pressure, and is often complicated by co-existing lesions, and is modified by cerebral blood flow (CBF) changes, coagulopathy, and delayed hematomas. Because of its complicated pathophysiology, the mortality of ASDH is still remaining high. In this review article, its epidemiology, pathophyiology, surgical treatment, and salvage ability are described. With regard to epidemiology, as the population ages, growing number of elderly patients with ASDH, especially patients with prehospital anticoagulant and antiplatelets, increase. Concerning pathophysiology, in addition to well-known initial intracranial hypertension and subsequent ischemia, delayed hyperemia/hyperperfusion, or delayed hematoma is being recognized frequently in recent years. However, optimal treatments for these delayed phenomenons have not been established yet. With regard to surgical procedures, all of craniotomy, decompressive craniectomy, and initial trephination strategies seem to be effective, but superiority of each procedure have not been established yet. Since Glasgow Coma Scale (GCS) scores, age, papillary reaction, and computed tomographic findings are strongly correlated to outcome, each factor has been investigated as an indicator of salvage ability. None of them, however, has been defined as such one. In future studies, epidemiological changes as population ages, management of delayed pathophysiology, superiority of each surgical procedures, and salvage ability should be addressed. PMID:25367584

    Pretreatment assessment of cytogenetic/genetic signature of acute myeloid leukemia (AML) has been consistently shown to play a major prognostic role but also to fail at predicting outcome on individual basis, even in low-risk AML. Therefore, we are in need of further accurate methods to refine the patients’ risk allocation process, distinguishing more adequately those who are likely to recur from those who are not. In this view, there is now evidence that the submicroscopic amounts of leukemic cells (called minimal residual disease, MRD), measured during the course of treatment, indicate the quality of response to therapy. Therefore, MRD might serve as an independent, additional biomarker to help to identify patients at higher risk of relapse. Detection of MRD requires the use of highly sensitive ancillary techniques, such as polymerase chain reaction (PCR) and multiparametric flow cytometry(MPFC). In the present manuscript, we will review the current approaches to investigate MRD and its clinical applications in AML management. PMID:27872732

    The aim of the study was to evaluate the dorsal and lumbar spine of expert and recreational tennis players before (pre) and after (post) two different training sessions. The sample consisted of 17 male tennis players, nine expert and eight recreational males (age 21.2 ± 1.6 years). We assessed the back surface by rasterstereography pre and post two different training sessions both lasting 1.5 h: a standard training and a specific over-shoulder shots training session, respectively. Lordotic and kyphotic angle, length, imbalance, inclination for trunk, pelvic torsion, left and right lateral deviation and surface rotation were measured. Tennis expertise (expert versus recreational) significantly affected the surface rotation and right lateral deviation (P tennis players had higher values on surface rotation and right lateral deviation, around or just above physiological values (0-5° and 0-5 mm, respectively). Type of session significantly affected left lateral deviation, indicating that over-shoulder shots lead to a higher stress for the spine; the workload produced by both single sessions led to a shortening effect on trunk length. A single training session can induce acute modifications in some parameters of dorsal and lumbar spine of players.

    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 urinary tract infections. Urinary isolated susceptibility testing was done by micro broth dilution (MBD). Treatment duration was 5-7 days. Cure was defined as eradication of the uropathogen and failure was defined as minimal/no decrease in urine colony counts. Of 26 evaluable patients with renal insufficiency (CrCl < 60 ml/min), nitrofurantoin eradicated the uropathogen in 18/26 (69%) of patients, and failed in 8/26 (31%). Of the eight failures, five were due to intrinsically resistant uropathogens, e.g., Proteus sp., and one failure was related to an alkaline urine. Of the treatment failures, only two were due to renal insufficiency, i.e., CrCl < 30 ml/min. Since there are few oral antibiotics available to treat AUC due to MDR GNB uropathogens, these results have important ASP implications. Currently, nitfurantoin is not recommended if CrCl < 60 ml/min. In our experience, used appropriately against susceptible uropathogens, nitrofurantoin was highly effective in nearly all patients with CrCl = 30-60 ml/min., and only failed in two patients due to renal insufficiency (CrCl < 30 ml/ml).

    The prognostic value of minimal residual disease (MRD) assessed by multi-parameter flow cytometry (MFC) was investigated among 340 adult patients with B-cell acute lymphoblastic leukaemia (B-ALL) treated between 2004 and 2014 using regimens including the hyperCVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin, dexamethasone, methotrexate, cytarabine) backbone. Among them, 323 (95%) achieved complete remission (CR) and were included in this study. Median age was 52 years (range, 15-84). Median white blood cell count (WBC) was 9·35 × 10(9) /l (range, 0·4-658·1 ×1 0(9) /l). MRD by MFC was initially assessed with a sensitivity of 0·01%, using a 15-marker, 4-colour panel and subsequently a 6-colour panel on bone marrow specimens obtained at CR achievement and at approximately 3 month intervals thereafter. MRD negative status at CR was associated with improved disease-free survival (DFS) and overall survival (OS) (P = 0·004 and P = 0·03, respectively). Similarly, achieving MRD negative status at approximately 3 and 6 months was associated with improved DFS (P = 0·004 and P < 0·0001, respectively) and OS (P = 0·004 and P < 0·0001, respectively). Multivariate analysis including age, WBC at presentation, cytogenetics (standard versus high risk) and MRD status at CR, 3 and 6 months, indicated that MRD negative status at CR was an independent predictor of DFS (P < 0·05). Achievement of an MRD negative state assessed by MFC is an important predictor of DFS and OS in adult patients with ALL.

    Full Text Available Abstract Background Gastrointestinal symptoms are not an uncommon manifestation of an influenza virus infection. In the present study, we aimed to investigate the presence of influenza viruses in the stools of adult patients consulting their general practitioner for uncomplicated acute diarrhea (AD and the proportion of concurrent infections by enteric and influenza viruses. Method A case-control study was conducted from December 2010 to April 2011. Stool specimens were collected and tested for influenza viruses A (seasonal A/H3N2 and pandemic A/H1N1 and B, and for four enteric viruses (astrovirus, group A rotavirus, human enteric adenovirus, norovirus of genogroups I – NoVGI - and genogroup II - NoVGII. Results General practitioners enrolled 138 cases and 93 controls. Of the 138 stool specimens collected, 92 (66.7% were positive for at least one of the four enteric viruses analysed and 10 (7.2% tested positive for one influenza virus. None of these 10 influenza positive patients reported respiratory symptoms. In five influenza-positive patients (3.6%, we also detected one enteric virus, with 4 of them being positive for influenza B (2 had co-detection with NoVGI, 1 with NoVGII, and 1 with astrovirus. None of the 93 controls tested positive for one of the enteric and/or other influenza viruses we investigated. Conclusions In this study we showed that the simultaneous detection of influenza and enteric viruses is not a rare event. We have also reported, for the first time in general practice, the presence of seasonal and pandemic influenza viruses in the stools of adult patients consulting for uncomplicated AD. A simultaneous investigation of enteric and influenza viruses in patients complaining of gastrointestinal symptoms could be useful for future studies to better identify the agents responsible for AD.

    Management of the acute painful crisis (APC) of sickle cell disease (SCD) remains unsatisfactory despite advances in the understanding and management of acute pain in other clinical settings. One reason for this is an unsophisticated approach to the use of opioid analgesics for pain management. This applies to haematologists who are responsible for developing acute sickle pain management protocols for their patients, and to health care staff in the acute care setting. The objective of this article is to evaluate the evidence for use of opioids in APC management. We have highlighted the possibilities for improving management by using alternatives to morphine, and intranasal (IN) or transmucosal routes of administration for rapid onset of analgesia in the emergency department (ED). We suggest how experience gained in managing acute sickle pain in children could be extrapolated to adolescents and young adults. We have also questioned whether patients given strong opioids in the acute setting are being safely monitored and what resources are required to ensure efficacy, safety and patient satisfaction. We also identify aspects of care where there are significant differences of opinion, which require further study by randomized controlled trial.

    Central venous catheters (CVC) related thrombosis (CRT) represents a well known complication in patients with acute myeloid leukemia (AML) receiving intensive chemotherapy but the efficacy of antithrombotic prophylaxis still remains controversial. We analyzed 71 consecutive AML patients whose CVC was inserted before each chemotherapy cycle for an overall number of 106 CVC placements. In 47/106 insertions, a prophylaxis with 100 IU/kg/day low molecular weight heparin (LMWH) was administered for 7 days after CVC insertion and additional 7 after CVC removal. This unconventional dose of LMWH, although higher than usual, appeared adequate for a short-course approach. LMWH was delivered regardless of the platelet (PLT) count once provided that it should have been maintained above 20 x 10(9)/L by transfusions. Of 106 insertions, we observed 19 (18%) episodes of CRT, 58 (54%) of sepsis and 50 (47%) infections of CVC-exit site with no difference between LMWH and no-LMWH group. Occurrence of CRT was significantly associated with CVC-exit site infections (14/19, p=0.01) and sepsis (16/19, p=0.005) with no difference between LMWH and no-LMWH group. In multivariate analysis, both CVC-exit site infections and sepsis were confirmed to be independent risk factors for CRT development. Our retrospective study, although based on a small sample size, suggests that the occurrence of CVC-exit site infections and neutropenic sepsis following chemotherapy significantly increases the risk of CRT in AML, independently from the use of LMWH prophylaxis. © 2013.

    Patients with acute myeloid leukemia (AML) with hyperleukocytosis of at least 100 x 10(9) per L are at high risk of early death due to pulmonary or cerebral leukostasis. Although the efficacy of leukapheresis in terms of prompt cytoreduction is generally accepted, published data regarding the clinical value of immediate therapeutic leukapheresis are limited and conflicting. To determine whether leukapheresis has a favorable impact on early mortality, the clinical course of 53 newly diagnosed patients with AML and hyperleukocytosis admitted between 1995 and 2005 was analyzed retrospectively. Before August 2001, 28 patients received chemotherapy without leukoreduction (Cohort A). Thereafter, all AML patients with hyperleukocytosis were scheduled to receive leukapheresis, which was performed in 25 patients (Cohort B). There were no procedure-related adverse events. By Day 21 of therapy, 13 of 53 patients had died, resulting in an overall early death rate of 25 percent. In a multivariate logistic regression model, patients in Cohort B had a significantly lower risk of early death than patients in Cohort A (16% vs. 32%, respectively; p = 0.015). Dyspnea (p = 0.005), elevated creatinine (p = 0.028), and higher lactate dehydrogenase serum levels (p = 0.021) were independent risk factors for early death. With a median follow-up of 24.2 months, the overall survival was similar in both cohorts (Cohort A, 7.5; Cohort B, 6.5 months). Thus, leukapheresis had no impact on patients' long-term survivals. Our experience suggests that AML patients with hyperleukocytosis receiving leukapheresis had a significantly lower risk for early death by Day 21 than patients treated without leukapheresis. We therefore have adopted leukapheresis as a standard procedure in our department.

  5. Acute and chronic estrogen supplementation decreases uterine sympathetic innervation in ovariectomized adult virgin rats.

    Uterine innervation undergoes substantial reorganization associated with changes in reproductive status. Nerves innervating the uterus are decreased in pregnancy and puberty, and even the normal rodent estrous cycle is characterized by fluctuations in numbers of myometrial nerve fibers. During the follicular (proestrus/estrous) phase of the estrous cycle, intact nerves are rapidly depleted and then return over the next 2-3 days in the luteal (metestrus/diestrus) phase. We hypothesize that uterine nerve depletion is initiated by increased circulating estrogen in the follicular phase. However, studies have not shown whether estrogen can reduce uterine innervation and, if so, whether the time course is compatible with the rapid changes observed in the estrous cycle. These questions were addressed in the present study. Mature ovariectomized virgin rats received 17-beta-estradiol as a single injection (10 microg/kg s.c.) or chronically from timed-release pellets (0.1 microg/pellet for 3 weeks sustained release). Total (protein gene-product 9.5-immunoreactive) and sympathetic (dopamine beta-hydroxylase-immunoreactive) uterine innervation was assessed quantitatively. Both total and sympathetic innervation was abundant in uterine longitudinal smooth muscle of ovariectomized rats. However, following acute or chronic estrogen administration, total and sympathetic fiber numbers were markedly decreased. This was not due to altered uterine size, as reductions persisted after correcting for size differences. Our results indicate that sympathetic nerves are lost from uterine smooth muscle after estradiol treatment in a manner similar to that seen in the intact animal during estrus and pregnancy. This suggests that the rise in estradiol prior to estrus is sufficient to deplete uterine sympathetic innervation.

  6. Allogeneic hematopoietic cell transplantation for acute myeloid leukemia in older adults.

    Acute myeloid leukemia (AML) is primarily a disease of the elderly and the numbers of these patients are increasing. Patients ≥60 years of age continue to have poor prognosis. Preliminary results suggest benefit from reduced-intensity allogeneic hematopoietic cell transplantation (HCT) in selected patients 60-80 years of age. However, although patients in this age range comprise >50% of those with AML, they currently constitute only 17% of those offered HCT. In the absence of prospective randomized studies comparing HCT and chemotherapy, the decision to recommend HCT rests on retrospective analyses of the risks of relapse and nonrelapse mortality after each approach. There is strong evidence that pre-HCT comorbidities can predict HCT-related morbidity and mortality. Age alone does not appear predictive and, particularly if the risk of relapse with chemotherapy is high, should not be the sole basis for deciding against HCT. Use of geriatric assessment tools, inflammatory biomarkers, and genetic polymorphism data may further aid in predicting nonrelapse mortality after HCT. Disease status and pretreatment cytogenetics with FLT3-TID, NPM-1, and CEBP-α status are the main factors predicting relapse and these are likely to be supplemented by incorporation of other molecular markers and the level of minimal residual disease after chemotherapy. HLA-matched related and unrelated donor grafts seem preferable to those from other donor sources. Donor age is of no clear significance. Models combining comorbidities with AML risk factors are useful in risk assessment before HCT. In this chapter, we integrated information on AML-specific, HCT-specific, and patient-specific risk factors into a risk-adapted approach to guide decisions about HCT versus no HCT.

    Although delirium is a common medical comorbidity with altered cognition as its defining feature, few publications have addressed the neuropsychological prodrome, profile, and recovery of patients tested during delirium. We characterize neuropsychological performance in 54 hemapoietic stem cell/bone marrow transplantation (BMT) patients shortly before, during, and after delirium and in BMT patients without delirium and 10 healthy adults. Patients were assessed prospectively before and after transplantation using a brief battery. BMT patients with delirium performed more poorly than comparisons and those without delirium on cross-sectional and trend analyses. Deficits were in expected areas of attention and memory, but also in psychomotor speed and learning. The patients with delirium did not return to normative “average” on any test during observation. Most tests showed a mild decline in the visit before delirium, a sharp decline with delirium onset, and variable performance in the following days. This study adds to the few investigations of neuropsychological performance surrounding delirium and provides targets for monitoring and early detection; Trails A and B, RBANS Coding, and List Recall may be useful for delirium assessment.

    Bacterial meningitis is a medical emergency, the outcome of which is improved by prompt antibiotic treatment. For patients with suspected meningitis and no features of severe disease, the British Infection Society recommends immediate lumbar puncture (LP) before antibiotics, to maximise the chance of a positive cerebrospinal (CSF) culture. In such patients, CT scanning before LP is not needed. The case notes of adults with meningitis admitted to a large district general hospital over 3 years were reviewed. Patients were classified as Likely Bacterial Meningitis or Likely Viral Meningitis based on their CSF and peripheral blood results using the Meningitest Criteria, with microbiological and virological confirmation. Of 92 patients studied, 24 had Likely Bacterial Meningitis, including 16 with microbiologically confirmed disease (none had PCR tests for bacteria). Sixty-eight had Likely Viral Meningitis, four of whom had viral PCR, including one with herpes simplex virus. No patient had an LP before antibiotics. CSF culture was positive for eight (73%) of the 11 patients who had an LP up to 4 h after starting antibiotics, compared with eight (11%) of 71 patients with a later LP (pacute bacterial meningitis are being sent for unnecessary CT scans, causing delays in the LP, and reducing the chances of a positive CSF culture after starting antibiotics. However, even if antibiotics have been started, an LP within 4 h is still likely to be positive. Molecular tests for diagnosis should also be requested.

  10. Effects of Acute Blueberry Flavonoids on Mood in Children and Young Adults

    Full Text Available Epidemiological evidence suggests that consumption of flavonoids (usually via fruits and vegetables is associated with decreased risk of developing depression. One plausible explanation for this association is the well-documented beneficial effects of flavonoids on executive function (EF. Impaired EF is linked to cognitive processes (e.g., rumination that maintain depression and low mood; therefore, improved EF may reduce depressionogenic cognitive processes and improve mood. Study 1: 21 young adults (18–21 years old consumed a flavonoid-rich blueberry drink and a matched placebo in a counterbalanced cross-over design. Study 2: 50 children (7–10 years old were randomly assigned to a flavonoid-rich blueberry drink or a matched placebo. In both studies, participants and researchers were blind to the experimental condition, and mood was assessed using the Positive and Negative Affect Schedule before and 2 h after consumption of the drinks. In both studies, the blueberry intervention increased positive affect (significant drink by session interaction but had no effect on negative affect. This observed effect of flavonoids on positive affect in two independent samples is of potential practical value in improving public health. If the effect of flavonoids on positive affect is replicated, further investigation will be needed to identify the mechanisms that link flavonoid interventions with improved positive mood.

    Although interleukin-6 (IL-6) has been investigated frequently in stress research, knowledge regarding the biological processes of IL-6 in association with psychosocial stress remains incomplete. This study focused on salivary IL-6 and reports its temporal variation and biological correlates following acute psychosocial stress. Fifty healthy young adults (39 male and 11 female students) were subjected to the psychosocial stress test 'Trier Social Stress Test' (TSST), wherein the participants were asked to deliver a speech and perform a mental arithmetic task in front of 2 audiences. Collection of saliva samples, measurement of heart rate, and assessment of negative moods by visual analogue scales were conducted before, during, and after TSST. Salivary IL-6 levels increased by approximately 50% in response to the TSST and remained elevated for 20 min after the stress tasks were completed. Cluster analyses revealed that individuals with sustained elevation of IL-6 levels following the TSST exhibited a lower cortisol response compared to individuals with lower IL-6 levels. In the correlation analyses, a greater IL-6 response was associated with a higher heart rate during the mental arithmetic task (r=.351, ppsychosocial stress, and suggests that sympathetic activity and cortisol secretion are involved in elevation of salivary IL-6 levels.

    Fifteen consecutive patients with refractory adult acute leukemia (RAAL) were treated with a combination of high-dose, continuous-infusion cyclophosphamide, cytarabine, vincristine, and prednisone (Hi-COAP). The initial nine patients received cyclophosphamide 350 mg/m2 as a 24-hour intravenous (IV) infusion over 5 days; cytarabine, 100 mg/m2 IV bolus every 12 hours for ten doses; vincristine, 2.0 mg IV bolus on day 1; and prednisone, 100 mg orally for 7 days. The last six patients had the cyclophosphamide infusion lengthened to 7 days, and the cytarabine increased to 14 doses. All patients were evaluable for toxicity and response. Seven patients (47%) obtained a complete remission and six patients (40%) a partial remission. Median duration of all remissions has been 7.0 months with a range of 1 to 32 months. Toxicity has been limited to primarily myelosuppression with no hemorrhagic cystitis, central nervous system (CNS), hepatic, or pulmonary toxicity noted. Gastrointestinal toxicity was mild, with no effect on nutritional status noted. Median duration of complete responders was 8.5 months. Thus, Hi-COAP demonstrates promising efficacy with minimal toxicity in RAAL and warrants further exploration in multiinstitutional trials.

    To assess the risks for adult-onset acute leukemia associated with employment in the New Zealand meat industry. A total of 110 incident leukemia cases identified from referrals to one of six treatment centers between 1989 and 1991 were compared with 199 general population controls. Detailed occupational exposure histories were obtained by interview. There was an elevated risk associated with ever having worked in an abattoir (OR = 2.3, 95% CI 1.0-5.2), which appeared confined to those with over 2 years exposure (OR = 4.9, 95% CI 1.5-15.6). The excess risk was confined to abattoir workers having direct contact with animals or animal products (OR = 5.2 95% CI 1.2-22.2). Ever having worked as a butcher was associated with elevated risk (OR = 2.9, 95% CI 1.1-7.2), confined to those individuals who worked as a butcher in an abattoir (OR = 4.8) or who butchered livestock on farms (OR = 8.2). No increased risk was found for work as a retail/wholesale butcher or meatpacker (OR = 1.2). This study found increased leukemia risks associated with employment in the meat industry. These were confined to abattoir workers with over 2 years employment in the industry, and to persons whose jobs involved contact with animals or animal tissue, implying that biological exposures may be responsible.

    Despite interest in dopamine's role in emotion-based decision-making, few reports of the effects of dopamine manipulations are available in this area in humans. This study investigates dopamine's role in emotion-based decision-making through a common measure of this construct, the Iowa Gambling Task (IGT), using Acute Tyrosine Phenylalanine Depletion (ATPD). In a between-subjects design, 40 healthy adults were randomized to receive either an ATPD beverage or a balanced amino acid beverage (a control) prior to completing the IGT, as well as pre- and post-manipulation blood draws for the neurohormone prolactin. Together with conventional IGT performance metrics, choice selections and response latencies were examined separately for good and bad choices before and after several key punishment events. Changes in response latencies were also used to predict total task performance. Prolactin levels increased significantly in the ATPD group but not in the control group. However, no significant group differences in performance metrics were detected, nor were there sex differences in outcome measures. However, the balanced group's bad deck latencies speeded up across the task, while the ATPD group's latencies remained adaptively hesitant. Additionally, modulation of latencies to the bad decks predicted total score for the ATPD group only. One interpretation is that ATPD subtly attenuated reward salience and altered the approach by which individuals achieved successful performance, without resulting in frank group differences in task performance.

    Abstract There are limited data describing acute kidney injury (AKI) in HIV-infected adult patients in resource-limited settings where tenofovir disoproxil fumarate (TDF), which is potentially nephrotoxic, is increasingly prescribed. We describe risk factors for and prognosis of AKI in HIV-infected individuals, stratified by those receiving and those naive to TDF. A prospective case cohort study of hospitalized HIV-infected adults with AKI stratified by TDF exposure. Adults (≥18 years) were recruited: clinical and biochemical data were collected at admission; their renal recovery, discharge, or mortality was ascertained as an in-patient and, subsequently, to a scheduled 3-month follow-up. Among this predominantly female (61%), almost exclusively black African cohort of 175 patients with AKI, 93 (53%) were TDF exposed; median age was 41 years (interquartile range 35–50). Median CD4 count and viral load and creatinine at baseline were 116 cells/mm3 and 110,159 copies/ml, respectively. A greater proportion of the TDF group had severe AKI on admission (61% vs. 43%, p = .014); however, both groups had similar rates of newly diagnosed tuberculosis (TB; 52%) and nonsteroidal anti-inflammatory drug (NSAID; 32%) use. Intravenous fluid was the therapeutic mainstay; only seven were dialyzed. Discharge median serum creatinine (SCr) was higher in the TDF group (p = .032) and fewer in the TDF group recovered renal function after 3 months (p = .043). Three-month mortality was 27% in both groups, but 55% of deaths occurred in hospital. Those that died had a higher SCr and more severe AKI than survivors; TB was diagnosed in 33 (70%) of those who died. AKI was more severe and renal recovery slower in the TDF group; comorbidities, risk factors, and prognosis were similar regardless of TDF exposure. Because TB is linked to higher mortality, TB coinfection in HIV-infected patients with AKI warrants more intensive monitoring. In all those with poor renal recovery, our

    Background: Dialysis-dependent acute kidney injury (AKI) can be treated using continuous (CRRT) or intermittent renal replacement therapies (IRRT). Although some studies suggest that CRRT may have advantages over IRRT, study findings are inconsistent. This study assessed differences between CRRT and IRRT regarding important clinical outcomes (such as mortality and renal recovery) and cost-effectiveness. Additionally, ethical aspects that are linked to renal replacement therapies in the intensive care setting are considered. Methods: Systematic searches in MEDLINE, EMBASE, and Cochrane Library including RCTs, observational studies, and cost-effectiveness studies were performed. Results were pooled using a random effects-model. Results: Forty-nine studies were included. Findings show a higher rate of renal recovery among survivors who initially received CRRT as compared with IRRT. This advantage applies to the analysis of all studies with different observation periods (Relative Risk (RR) 1.10; 95% Confidence Interval (CI) [1.05, 1.16]) and to a selection of studies with observation periods of 90 days (RR 1.07; 95% CI [1.04, 1.09]). Regarding observation periods beyond there are no differences when only two identified studies were analyzed. Patients initially receiving CRRT have higher mortality as compared to IRRT (RR 1.17; 95% CI [1.06, 1.28]). This difference is attributable to observational studies and may have been caused by allocation bias since seriously ill patients more often initially receive CRRT instead of IRRT. CRRT do not significantly differ from IRRT with respect to change of mean arterial pressure, hypotensive episodes, hemodynamic instability, and length of stay. Data on cost-effectiveness is inconsistent. Recent analyzes indicate that initial CRRT is cost-effective compared to initial IRRT due to a reduction of the rate of long-term dialysis dependence. As regards a short time horizon, this cost benefit has not been shown. Conclusion: Findings of

    Full Text Available Epidemiological data of renal diseases have great geographic variability throughout the world. Due to the lack of a national renal data registry system, there is no information on the prevalence rate, clinical and pathological features of various glomerulonephritis (GN in the United Arab Emirates (UAE. In a retrospective cross-sectional study, we analyzed 158 renal biopsies done in Dubai Hospital, UAE, between the years of 2005 and September 2014, with an aim to determine the prevalence rate and frequency of different pathological patterns of GN in adult patients who presented with proteinuria ± hematuria. In our study, primary GN still remains more common than secondary GN (66.4% vs. 33.5%. Among the primary GN in our analysis, minimal change disease was the most common primary GN affecting 20% of the study population (13.2% of the total GN causes followed with membranous GN (18.2%, then membrano- proliferative GN (15.3% and focal segmental glomerulosclerosis (13.46%, while among the secondary causes lupus nephritis (LN is the most prevalent GN in UAE, predominantly in the Emirati national population whom constituted 48% of total biopsies. Indeed, LN had the highest incidence among all types of GN even the primary ones, constituting 23.4% of total GN in Dubai (74% of the total secondary causes. Furthermore, systemic lupus erythematosus was the most common GN in women while the minimal change was widely affecting male patients. Among elderly, the most common pathology was diabetic glomerulosclerosis followed by amyloidosis.

    In animal models, a small (catalytic) dose of fructose administered with glucose decreases the glycemic response to the glucose load. Therefore, we examined the effect of fructose on glucose tolerance in 11 healthy human volunteers (5 men and 6 women). Each subject underwent an oral glucose tolerance test (OGTT) on 2 separate occasions, at least 1 week apart. Each OGTT consisted of 75 g glucose with or without 7.5 g fructose (OGTT+F or OGTT-F), in random order. Arterialized blood samples were obtained from a heated dorsal hand vein twice before ingestion of the carbohydrate and every 15 min for 2 h afterward. The area under the curve (AUC) of the change in plasma glucose was 19% less in OGTT+F vs. OGTT-F (P: Glucose tolerance was improved by fructose in 9 subjects and worsened in 2. All 6 subjects with the largest glucose AUC during OGTT-F had a decreased response during OGTT+F (31 +/- 5% decrease). The insulin AUC did not differ between the 2 studies. Of the 9 subjects with improved glucose tolerance during the OGTT+F, 5 had smaller insulin AUC during the OGTT+F than the OGTT-F. Plasma glucagon concentrations declined similarly during OGTT-F and OGTT+F. The blood lactate response was about 50% greater during the OGTT+F (P: fructose improves the glycemic response to an oral glucose load in normal adults without significantly enhancing the insulin or triglyceride response. Fructose appears most effective in those normal individuals who have the poorest glucose tolerance.

  2. Acute and old ruptures of the extensor apparatus of the knee in adults (excluding knee replacement).

    Rupture of the extensor apparatus of the knee in adults is infrequent and dominated by patellar fracture, which in our experience is six times as frequent as quadriceps or patellar tendon tear. Patellar fracture poses few diagnostic problems and treatment is now well codified. Tension-band osteosynthesis is generally used, involving two longitudinal K-wires and wire in a figure-of-eight pattern looped over the anterior patella; sometimes, for more complex fractures, cerclage wiring is added to the tension band. Non-union is rare and generally well tolerated. Quadriceps tendon tear mainly affects patients over 40 years of age, in a context of systemic disease. Diagnosis is easily suggested by inability to actively extend the knee, but is unfortunately still often overlooked in emergency. In most cases, early surgical management is needed to reinsert the tendon at the proximal pole of the patella by bone suture. For chronic lesions, it is often necessary to lengthen the quadriceps tendon by V-Y plasty or the Codivilla technique. Patellar tendon tear, on the other hand, typically occurs in patients under 40 years of age, often involved in sports. Diagnosis is again clinically straightforward, but again may be missed in emergency, especially in case of incomplete tear. Surgery is mandatory in all cases. The procedure depends on the type of lesion: either end-to-end suture or transosseous reinsertion. In most cases repair is protected by tendon augmentation. Old lesions often require tendon graft or a tendon-bone-tendon-bone graft taken from the opposite side.

    Summary Double-unit cord blood (CB) grafts may improve engraftment and relapse risk in adults with haematological malignancies. We performed a prospective high-dose myeloablative double-unit CB transplantation (CBT) trial in adults with high-risk acute leukaemia or myelodysplasia (MDS) between 2007 and 2011. The primary aim was to establish the one-year overall survival in a multi-centre setting. Fifty-six patients (31 acute myeloid leukaemia, 19 acute lymphoblastic leukaemia, 4 other acute leukaemias, 2 myelodysplastic syndrome [MDS]) were transplanted at 10 centres. The median infused total nucleated cell doses were 2.62 (larger unit) and 2.02 (smaller unit) × 107/kg. The cumulative incidence of day 100 neutrophil engraftment was 89% (95% confidence interval [CI]: 80–96). Day 180 grade II-IV acute graft-versus-host disease (GVHD) incidence was 64% (95%CI: 51–76) and 36% (95%CI: 24–49) of patients had chronic GVHD by 3-years. At 3-years post-transplant, the transplant-related mortality (TRM) was 39% (95%CI: 26–52), and the 3-year relapse incidence was 11% (95%CI: 4–21). With a median 37-month (range 23–71) follow-up of survivors, the 3-year disease-free survival was 50% (95%CI: 37–63). Double-unit CBT is a viable alternative therapy for high-risk acute leukaemia/MDS in patients lacking a matched unrelated donor. This is especially important for minority patients. The relapse incidence was low but strategies to ameliorate TRM are needed. PMID:25272241

    An increased risk of adult myeloid leukemia (AML) has recently been associated with lifestyle and environmental exposures, including obesity, smoking, some over the counter medications, and rural/farm habitats in case control studies. The association of these exposures with AML cytogenetic categories, outcomes after therapy, and overall survival is unknown. Relevant exposures were evaluated in a cohort of 295 consecutive AML patients diagnosed and treated at Mayo Clinic in Florida and Arizona. Standard cytogenetic risk categories were applied and reviewed in a central cytogenetic laboratory. The association of epidemiologic exposures with cytogenetic risk, complete remission after therapy, and overall survival was evaluated using logistic and Cox regression models. A significant association between obesity and intermediate-abnormal cytogenetics was identified (OR: 1.94, P=0.025). Similarly, those with secondary AML were more likely to have poor risk (OR: 2.55, P<0.001) and less likely to have intermediate normal (OR: 0.48, P=0.003) cytogenetics. In multivariate analysis, overall survival was improved for patients ≥ 60 years receiving intensive (RR: 0.21, P<0.001) and non-intensive therapy (RR: 0.40, P<0.001 compared to no treatment, and was lower for users of tobacco (RR 1.39, P=0.032), and those with poor risk cytogenetics (RR: 3.96, P=0.002) or poor performance status (RR: 1.69, P<0.001). Furthermore, an association between statin use at the time of diagnosis (OR: 2.89, P=0.016) and increased complete remission after intensive chemotherapy was identified, while prior solid organ transplantation was associated with significantly lower complete remission rate after therapy (OR: 0.10, P=0.035). Our results provide evidence that specific epidemiologic exposures, including obesity, are significantly associated with unique AML cytogenetic risk categories and response to therapy. This supports a link between patient lifestyles, clinical exposures, and leukemogenesis

    Therapy-related acute myeloid leukemia (t-AML) associated with radioiodine treatment (RAI) is emerging as an important clinical entity with the rise in incidence of thyroid cancer. We conducted an electronic search of MEDLINE and EMBASE, and also searched reference lists of articles and abstracts from conference proceedings for case reports and review articles on t-AML following radioiodine therapy. A total of 37 patients with acute myeloid neoplasms following radioiodine treatment were analyzed. The median RAI dose was 324 mCi, and median age was 47.5 years with M/F ratio of 1:3. Latency period was 1-4 years, and the median time from RAI exposure to diagnosis of t-AML was 2.9 years. FAB M2 and M3 were the two most common t-AML subtypes reported. Seventy-one percent of the cases that reported cytogenetic abnormalities were classified as unfavorable. The most commonly reported abnormalities were del 5q and t(15:17). Survival outcomes were not reported due to lack of patient-level data. T-AML following radioiodine therapy for thyroid cancer appears to have a shorter latency period than other types of t-AML, which is an important consideration for post-therapy surveillance. Reporting of cases and outcomes will help provide data for further research. Identifying biomarkers that help risk-stratify patients prior to therapy and specific genetic-guided therapies may help improve outcomes.

    Full Text Available OBJECTIVE: Mutations of the nucleophosmin (NPM1 gene are considered as the most frequent acute myeloid leukemia (AML- associated genetic lesion, reported with various incidences in different studies, and type A (NPM1-A is the most frequent type. However, since most series in the literature report on the features of all patients regardless of the type of mutation, NPM1-A(+ cases have not been well characterized yet. Therefore, we evaluated the prevalence of NPM1-A in Bulgarian AML patients and searched for an association with clinical and laboratory features. METHODS: One hundred and four adults (51 men, 53 women were included in the study. NPM1-A status was determined using allele-specific reverse-transcription polymerase chain reaction with co-amplification of NPM1-A and β-actin and real-time quantitative TaqMan-based polymerase chain reaction. Patients received conventional induction chemotherapy and were followed for 13.2±16.4 months. RESULTS: NPM1-A was detected in 26 (24.8% patients. NPM1-A mutation was detected in all AML categories, including in one patient with RUNX1-RUNX1T1. There were no differences associated with the NPM1-A status with respect to age, sex, hemoglobin, platelet counts, percentage of bone marrow blasts, splenomegaly, complete remission rates, and overall survival. NPM1-A(+ patients, compared to NPM1-A(- patients, were characterized by higher leukocyte counts [(75.4±81.9x109/L vs. (42.5±65.9x109/L; p=0.049], higher frequency of normal karyotype [14/18 (77.8% vs. 26/62 (41.9%; p=0.014], higher frequency of FLT3-ITD [11/26 (42.3% vs. 8/77 (10.4%; p=0.001], and lower incidence of CD34(+ [6/21 (28.8% vs. 28/45 (62.2%; p=0.017].

    Japanese encephalitis (JE) is numerically the most important global cause of encephalitis and so far confirmed to have caused major epidemics in India. Most of the reported studies have been in children. This largest study involving only adults, belonging to four epidemics, is being reported from Gorakhpur. The aim of this study is to detail the acute clinical profile (not viral) outcome and to classify the sequelae at discharge. This prospective study involved 1,282 adult patients initially diagnosed as JE admitted during the epidemics of 1978, 1980, 1988, and 1989, on identical clinical presentation and CSF examination. In the meantime, the diagnosis of JE was confirmed by serological and/or virological studies in only a representative number of samples (649 of 1,282 cases). Eighty-three left against medical advice (LAMA) at various stages, so 1,199 of 1,282 were available for the study. Peak incidence of [1,061 of 1,282 (83%)] of clinically suspected cases was from September 15 to November 2. Serum IgM and IgG were positive in high titers in 50.87% (330 of 649) and IgM positive in CSF in 88.75% (109 of 123) of the cases. JE virus could be isolated from CSF and brain tissue in 5 of 5 and 4 of 5 samples, respectively. Altered sensorium (AS) in (96%), convulsions (86%), and headache (85%) were the main symptoms for hospitalization by the third day of the onset. Other neurological features included hyperkinetic movements in 593 of 1,282 (46%)-choreoathetoid in 490 (83%) and bizarre, ill-defined in 103 (17%). The features of brain stem involvement consisted of opsoclonus (20%), gaze palsies (16%), and pupillary changes (48%) with waxing and waning character. Cerebellar signs were distinctly absent. Dystonia and decerebrate rigidity was observed in 43 and 6%, respectively, paralytic features in 17% and seizures in 30%. Many non-neurological features of prognostic importance included abnormal breathing patterns (ABP) (45%), pulmonary edema (PO) (33%), and upper

    To compare the acute hemodynamic effects of aerosolized iloprost and inhaled nitric oxide (NO) in adult congenital heart disease (CHD) patients with severe pulmonary arterial hypertension (PAH). One hundred and eighty five adult CHDs with severe PAH were nonrandomized into two groups (iloprost, n=127; NO, n=58). Various hemodynamic parameters were measured before and after iloprost or NO inhalation. Iloprost and NO inhalation resulted in significant reductions in pulmonary arterial pressure (from 110.6±21.8 mmHg to 105.5±22.3 mmHg, piloprost and NO were compared, similar reductions in pulmonary arterial pressure and pulmonary vascular resistance were observed. Aerosolized iloprost and inhaled nitric oxide (iNO) were generally well tolerated and no patient experienced any side effects during inhalation. Aerosolized iloprost can be effectively and safely used and might be an alternative to NO for testing pulmonary vascular reactivity and treating severe PAH in adult CHD patients.

    Full Text Available BACKGROUND: The gold standard for respiratory virus testing is a nasopharyngeal (NP swab, which is collected by a healthcare worker. Midturbinate (MT swabs are an alternative due to their ease of collection and possible self-collection by patients. The objective of this study was to compare the respiratory virus isolation of flocked MT swabs compared to flocked NP swabs. METHODS: Beginning in October 2008, healthy adults aged 18 to 69 years were recruited into a cohort and followed up for symptoms of influenza. They were asked to have NP and MT swabs taken as soon as possible after the onset of a fever or two or more respiratory symptoms with an acute onset. The swabs were tested for viral respiratory infections using Seeplex® RV12 multiplex PCR detection kit. Seventy six pairs of simultaneous NP and MT swabs were collected from 38 symptomatic subjects. Twenty nine (38% of these pairs were positive by either NP or MT swabs or both. Sixty nine (91% of the pair results were concordant. Two samples (3% for hCV OC43/HKU1 and 1 sample (1% for rhinovirus A/B were positive by NP but negative by MT. One sample each for hCV 229E/NL63, hCV OC43/HKU1, respiratory syncytial virus A, and influenza B were positive by MT but negative by NP. CONCLUSIONS: Flocked MT swabs are sensitive for the diagnosis of multiple respiratory viruses. Given the ease of MT collection and similar results between the two swabs, it is likely that MT swabs should be the preferred method of respiratory cell collection for outpatient studies. In light of this data, larger studies should be performed to ensure that this still holds true and data should also be collected on the patient preference of collection methods.

    This study evaluated daytime alertness and performance with lisdexamfetamine dimesylate during acute sleep loss. In a randomized, double-blind study in healthy adult men (n = 135) undergoing 24-hour sleep loss, the alerting effects of single oral lisdexamfetamine dimesylate doses (20, 50, or 70 mg) were compared with a placebo and an active control (armodafinil 250 mg). Primary end point was mean unequivocal sleep latency on the 30-minute maintenance of wakefulness test taken every 2 hours from midnight to 8:00 A.M. Secondary end points included the Karolinska sleepiness scale and psychomotor vigilance task. Safety assessments included treatment-emergent adverse events (TEAEs) and vital signs. Least squares mean (SE) maintenance of wakefulness test unequivocal sleep latency (in minutes) was longer with lisdexamfetamine dimesylate 20, 50, and 70 mg, or armodafinil 250 mg (23.3 [1.10], 27.9 [0.64], 29.3 [0.44], or 27.6 [0.63], respectively) versus placebo (15.3 [1.00]; P armodafinil (P = 0.0351) and armodafinil versus lisdexamfetamine dimesylate 20 mg (P = 0.0014). On Karolinska sleepiness scale, lisdexamfetamine dimesylate 50 and 70 mg improved estimated sleepiness versus placebo (P ≤ 0.0002) and armodafinil (P ≤ 0.03). Active treatments improved psychomotor vigilance task performance versus placebo (P armodafinil (7.4% each) versus placebo (3.7%). Small mean increases in vital signs were observed with lisdexamfetamine dimesylate and armodafinil. In sleep-deprived healthy men, alertness was greater with lisdexamfetamine dimesylate and armodafinil versus placebo on the primary end point. Studies are needed in clinical populations and using longer durations of administration.

    Background Various trials report improved outcomes for adolescents and young adults (AYA) with acute lymphoblastic leukemia (ALL) treated with pediatric- based regimens. This prompted the investigation of the pediatric Augmented Berlin-Frankfurt-Münster (ABFM) regimen in AYA patients. Results were compared with the hyper–fractionated cyclophosphamide, vincristine, Adriamycin and dexamethasone (hyper-CVAD) regimen in a similar population. Methods Eighty-five patients age 12 to 40 years with Philadelphia chromosome- (Ph) negative ALL were treated with ABFM from 10/2006 through 4/2012. Their outcome was compared to 71 historical AYA patients treated with hyper-CVAD from our institution. Patient and disease characteristics, as well as status of minimal residual disease (MRD), were analyzed for their impact on outcomes. Results The complete remission (CR) rate with ABFM was 94%. The 3-year complete remission duration (CRD) and overall survival (OS) rates were 70% and 74%, respectively. The 3-year CRD and OS were 72% and 85%, respectively, with age ≤ 21 years, and 69% and 60%, respectively, with age 21-40 years. Initial white blood cell count was an independent predictive factor of OS and CRD. The MRD status on Day 29 and Day 84 of therapy were also predictive of long-term outcomes. Severe regimen toxicities included transient hepatotoxicity in 35-39%, pancreatitis in 11%, osteonecrosis in 11%, and thrombosis in 22%. The 3-year OS rate was 74% with ABFM versus 71% with hyper-CVAD; the 3-year CRD rate was 70% with ABFM versus 66% with hyper-CVAD. Conclusion ABFM was tolerable in AYA patients with ALL but was not associated with significant improvements in CRD and OS compared with hyper-CVAD. PMID:25042398

    The etiology and epidemiology of 547 consecutive episodes of acute viral hepatitis in adults and diagnosed in a general hospital over 12 years (1983-1994) were prospectively analyzed as were the changes observed during the two halves of the study period. Of the 547 episodes, 25.4% were of type A, 41.1% type B, 21.9% type C, 6.6% non A, non B, non C, 2.4% type D, 1.1% by cytomegalovirus and 1.4% by the Epstein-Barr virus. The proportion of hepatitis A increased from 21.5% from 1983-1988 to 34.1% from 1989-1994 (p = 0.002), while hepatitis C decreased from 24.9% to 15.3% (p = 0.01) during the same periods. The proportion of hepatitis B observed in intravenous drug addicts fell from 56.1% in the first period to 39.3% in the second period (p = 0.03), while sexually transmitted hepatitis B rose from 7.3% to 22.9% (p = 0.002). A decrease was observed in the cases of hepatitis C in both periods in the intravenous drug addict cases (60.6% vs. 34.6%; p = 0.03) with an increase being observed in the C virus transmitted by unapparent mechanisms (2.1% vs. 23.1%; p = 0.001). These results suggest that modifications may currently be observed in the epidemiology of the viral hepatitis in Spain and that these trends should be taken into account when planning preventive strategies.

    To provide first data on inpatient costs and cost-driving factors due to nonrefractory status epilepticus (NSE), refractory status epilepticus (RSE), and super-refractory status epilepticus (SRSE). In 2013 and 2014, all adult patients treated due to status epilepticus (SE) at the university hospitals in Frankfurt, Greifswald, and Marburg were analyzed for healthcare utilization. We evaluated 341 admissions in 316 patients (65.7 ± [standard deviation]18.2 years; 135 male) treated for SE. Mean costs of hospital treatment were €14,946 (median €5,278, range €776-€152,911, €787 per treatment day) per patient per admission, with a mean length of stay (LOS) of 19.0 days (median 14.0, range 1-118). Course of SE had a significant impact on mean costs, with €8,314 in NSE (n = 137, median €4,597, €687 per treatment day, 22.3% of total inpatient costs due to SE), €13,399 in RSE (n = 171, median €7,203, €638/day, 45.0% of total costs, p costs, p cost-driving factors were SRSE, ventilation, and LOS of >14 days. Overall mortality at discharge was 14.4% and significantly higher in RSE/SRSE (20.1%) than in NSE (5.8%). Acute treatment of SE, and particularly SRSE and ventilation, are associated with high hospital costs and prolonged LOS. Extrapolation to the whole of Germany indicates that SE causes hospital costs of >€200 million per year. Along with the demographic change, incidence of SE will increase and costs for hospital treatment and sequelae of SE will rise. Wiley Periodicals, Inc. © 2016 International League Against Epilepsy.

    Full Text Available ABSTRACT Acute promyelocytic leukemia has good prognosis in view of the high complete remission and survival rates achieved with therapies containing all-trans retinoic acid or arsenic trioxide. However, there is a significant risk of death during induction due to hemorrhage secondary to disseminated intravascular coagulation. This has contributed to a gap in the prognosis of patients between developed and developing countries. The International Consortium on Acute Promyelocytic Leukemia was created in 2005 and proposed a treatment protocol based on daunorubicin and all-trans retinoic acid stratified by risk geared toward developing countries. Herein are presented the results from the first patient cohort treated in a single developing country hospital employing a slightly modified version of the International Consortium protocol in a real life setting. Twenty patients with acute promyelocytic leukemia were enrolled: 27.8% had low-risk, 55.6% intermediate risk and 16.7% high-risk. The complete remission rate was 94.4% after a median of 42 days. Both relapse rates and death rates were one patient (5.5% each. No deaths were observed during consolidation. After a median follow-up of 29 months, the overall survival rate was 89.1%. Efficacy and safety of the International Consortium on Acute Promyelocytic Leukemia protocol has been reproduced in acute promyelocytic leukemia patients from a developing country.

    2014-10-01

    Full Text Available Exercise stimulates cellular brain plasticity by extending the pool of proliferating neural precursor cells in the adult hippocampus. This effect has been investigated extensively, but the most immediate cellular effect induced by exercise that results in this acute increase in the number of cycling cells remained unclear. In the developing brain as well as adult pathological models, cell cycle alterations have a major influence on the balance between proliferative and neurogenic divisions. In this study we investigated whether this might also apply to the acute physiological pro-neurogenic stimulus of physical exercise in adulthood. Do changes in cell cycle precede the measurable increase in proliferation? After 5 days of voluntary wheel running, however, we measured only a very small, statistically not significant acceleration in cell cycle, which could not quantitatively explain the observed increase in proliferating cells after exercise. Thus, at this acute stage, changes at the level of cell cycle control is not the primary causal mechanism for the expansion of the precursor cell population, although with time after the stimulus changes in cell cycle of the entire population of labeled cells might be the result of the expanded pool of cells that have progressed to the advanced neurogenic stages with shorter cell cycle length.

    Factor V Leiden 1691G/A and prothrombin gene 20210G/A mutations are the most common genetic defects leading to thrombosis. This work aimed to study the FV Leiden and the prothrombin gene polymorphism in adult Egyptian patients with acute leukemia and their importance in thrombophilia screening. The study included 76 patients with acute leukemia and 100 healthy controls. Genotyping was done by real-time polymerase chain reaction technique. For factor V Leiden, the frequency of G/A mutation conferred more than 2.5-fold of increased risk of (OR 2.639 95 % CI 1.045-6.669). The frequency of factor V Leiden combined (G/A + A/A) genotypes conferred 2.83-fold of increased risk (OR 2.828, CI 1.13-7.075), The A allele conferred almost threefold increased risk (OR 2.824, 95 % CI 1.175-6.785). Despite higher frequency in patients compared to controls, there was no risk of association between prothrombin gene mutation and acute leukemia in adult Egyptians nor was there between combined genotypes of prothrombin gene mutation and factor V Leiden.

    Data about etiologic and demographic characteristics of acute poisoning in adults in Qatar are lacking. This prospective observational study was undertaken to analyze characteristics and possible determinants of acute poisoning in adults in Qatar. During 2010, 18,073 patients attended the emergency department of Hamad General Hospital, a teaching hospital in Qatar. Out of them, 599 (3.3%) patients were diagnosed as "poisoning case" with either chemical or pharmaceutical substances. The prevalence rate of poisoning incidence was 35.3/100,000 population. Seven patients died, corresponding with a case-fatality rate of 0.39/1000. The majority were male (65%) and the mean age was 34 years. The poisons involved were mainly chemicals (61.6%) and pharmaceuticals (38.4%). Female, mainly single, suffered more intentional poisoning compared to male. Of the patients aged 60 years and above (7.2%), the majority (95.3%) suffered unintentional poisoning with pharmaceuticals; 56% with warfarin, 12% with digoxin and 7% with insulin. Multivariate analysis shows that female gender, single status, younger than 35 years of age, being poisoned by pharmaceutical products, and the need for hospitalization are significant determinants for acute intentional poisoning after adjusting all other possible covariates. The findings of this study can be used to establish awareness and prophylactic campaigns in Qatar.

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

    Human aging is associated with reduced skeletal muscle perfusion during exercise, which may be a result of impaired endothelium-dependent dilation and/or attenuated ability to blunt sympathetically mediated vasoconstriction. Intra-arterial infusion of ascorbic acid (AA) increases nitric oxide-mediated vasodilation and forearm blood flow (FBF) during handgrip exercise in older adults, yet it remains unknown whether an acute oral dose can similarly improve FBF or enhance the ability to blunt sympathetic vasoconstriction during exercise. We hypothesized that 1) acute oral AA would improve FBF (Doppler ultrasound) and oxygen consumption (V̇o2) via local vasodilation during graded rhythmic handgrip exercise in older adults (protocol 1), and 2) AA ingestion would not enhance sympatholysis in older adults during handgrip exercise (protocol 2). In protocol 1 (n = 8; 65 ± 3 yr), AA did not influence FBF or V̇o2 during rest or 5% maximal voluntary contraction (MVC) exercise, but increased FBF (199 ± 13 vs. 248 ± 16 ml/min and 343 ± 24 vs. 403 ± 33 ml/min; P vasodilation.

  13. Melanopsin-Mediated Acute Light Responses Measured in Winter and in Summer: Seasonal Variations in Adults with and without Cataracts

    2017-09-01

    Full Text Available Seasonal adaptation is a ubiquitous behavior seen in many species on both global hemispheres and is conveyed by changing photoperiods. In humans this seasonal adaptation is less apparent, in part because changes in daylength are masked by the use of electrical lighting at night. On the other hand, cataracts which reduce light transmission, may compound seasonal changes related to the reduced daylength of winter. To better understand the effects of different photoperiod lengths in healthy adults without and with cataracts, we tested their melanopsin-mediated light responses in summer vs. winter. Fifty-two participants (mean age 67.4 years; 30 with bilateral cataracts and 22 age-matched controls with clear lenses; pseudophakes were tested twice, once in summer and once in winter. At each test session we assessed the electroretinogram and pupil responses during daytime and we determined melatonin suppression, subjective sleepiness and mood in response to light exposure in the evening. Circadian rest-activity cycles and sleep from activity recordings were also analyzed for both seasons. Both groups had similar visual function. There were no seasonal differences in the electroretinogram. For the pupil responses to bright blue light, the post-illumination pupil response (PIPR was greater in winter than summer in pseudophakes, but not in cataract participants, whereas melatonin suppression to acute light exposure showed no differences between both groups and seasons. Overall, intra-daily variability of rest-activity was worse in winter but participants felt sleepier and reported worse mood at the laboratory in evening time in the summer. Those with cataracts had poorer sleep quality with lower sleep efficiency, and higher activity during sleep in winter than summer. In this study, the PIPR showed a seasonal variation in which a larger response was found during winter. This variation was only detected in participants with a clear intraocular lens. In

    Transplantation of 2 unrelated cord blood (UCB) units instead of 1 has been proposed to increase the cell dose. We report a prospective randomized study, designed to compare single- vs double-UCB transplantation in children and young adults with acute leukemia in remission or myelodysplasia. Eligible patients had at least two 4-6 HLA-identical UCBs with >3 × 10(7) nucleated cells/kg for the first and >1.5 × 10(7) for the second. The primary end point was the 2-year cumulative incidence of transplantation strategy failure, a composite end point including transplant-related mortality (TRM), engraftment failure, and autologous recovery. Randomized patients who did not proceed to transplantation due to refractory disease were considered transplantation failures. A total of 151 patients were randomized and included in the intent-to-treat analysis; 137 were transplanted. Double-UCB transplantation did not decrease transplantation strategy failure (23.4% ± 4.9% vs 14.9% ± 4.2%). Two-year posttransplant survival, disease-free survival, and TRM were 68.8% ± 6.0%, 67.6% ± 6.0%, and 5.9% ± 2.9% after single-unit transplantation compared with 74.8% ± 5.5%, 68.1% ± 6.0%, and 11.6% ± 3.9% after double-unit transplantation. The final relapse risk did not significantly differ, but relapses were delayed after double-unit transplantation. Overall incidences of graft-versus-host disease (GVHD) were similar, but chronic GVHD was more frequently extensive after double-UCB transplantation (31.9% ± 5.7% vs 14.7% ± 4.3%, P = .02). In an exploratory subgroup analysis, we found a significantly lower relapse risk after double-unit transplantation in patients receiving total body irradiation without antithymocyte globulin (ATG), whereas the relapse risk was similar in the group treated with busulfan, cyclophosphamide, and ATG. Single-UCB transplantation with adequate cell dose remains the standard of care and leads to low TRM. Double-unit transplantation should be reserved for

    Event-related potential (ERP) is a reliable neuroelectric measure of brain activity that helps to confirm the assessment of mental status and cognitive impairment.Many studies have reported that alcoholics show a significantly lower ERP P300 amplitude than the norm.In the present study,ERP P300 waves were measured to evaluate the effect of citric acid on cognitive function during excessive alcohol consumption in healthy adults.Five volunteers were selected through clinical interview,physical examination,and psychiatric assessment for participation in this study.In a double-blind placebo-controlled before-after design,each subject was treated with 5 ml/kg body weight alcohol,5 ml/kg body weight alcohol and 1 mg citric acid,or a placebo on three separate occasions,one week apart.ERP P300,blood biochemical indicators,blood alcohol concentrations (BACs) and acetaldehyde concentrations were assessed.Repeated measure analysis of variance (ANOVA) with a within-subjects factor was used to evaluate differences in blood biochemical indicators,BACs,blood acetaldehyde concentrations,and ERP P300 in the three sessions of assessments.Several blood biochemical indicators showed significant differences between treatments,including the levels of cholinesterase (CHE),total bile acid (TBA),triglyceride (TG),total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),very low-density lipoprotein cholesterol (VLDL-C),and glycylproline dipeptidyl aminopeptidase (GPDA).BACs after consumption of alcohol alone or citric acid with alcohol were significantly higher compared to those after placebo treatment (P<0.05).There were no significant differences in blood acetaldehyde concentrations between the treatments.The P300 amplitudes on the frontal (Fz),central (Cz),and parietal (Pz) regions of the scalp after consumption of alcohol were significantly lower than those after consumption of the placebo or citric acid with alcohol (P<0

Before and after acute altitude exposure, the Athens Insomnia Scale score (AISS was used to evaluate the subjective sleep quality of subjects. AMS was assessed using the Lake Louise scoring system. Heart rate (HR and arterial oxygen saturation (SaO2 were measured.Results: Results showed that, at 500 m, AISS and insomnia prevalence were higher in older individuals. After acute exposure to altitude, the HR, AISS, and insomnia prevalence increased sharply, and the increase in older individuals was more marked. The opposite trend was observed for SaO2. At 3,700 m, the prevalence of AMS increased with age, as did severe AMS, and AMS symptoms (except gastrointestinal symptoms. Multivariate logistic regression analysis showed that age was a risk factor for AMS (adjusted odds ratio [OR] 1.07, 95% confidence interval [CI] 1.01–1.13, P<0.05, as well as AISS (adjusted OR 1.39, 95% CI 1.28–1.51, P<0.001.Conclusion: The present study is the first to demonstrate that older age is an independent risk factor for AMS upon rapid ascent to high altitude among young adult Chinese men, and pre-existing poor subjective sleep quality may be a contributor to increased AMS prevalence in older subjects.

    Objectives For millions of disabled older adults each year, post-acute care in skilled nursing facilities (SNFs) is a brief window of opportunity to regain enough function to return home and live independently. Too often this goal is not achieved, possibly due to therapy that is inadequately intense or engaging. This study tested Enhanced Medical Rehabilitation, an intervention designed to increase patient engagement in, and intensity of, daily physical and occupational therapy sessions in post-acute care rehabilitation. Design Randomized controlled trial of Enhanced Medical Rehabilitation versus standard-of-care rehabilitation. Setting Post-acute care unit of a skilled nursing facility in St Louis, MO. Participants 26 older adults admitted from a hospital for post-acute rehabilitation. Intervention Based on models of motivation and behavior change, Enhanced Medical Rehabilitation is a set of behavioral skills for physical and occupational therapists (PT/OT) that increase patient engagement and intensity, with the goal of improving functional outcome, through: (1) a patient-directed, interactive approach, (2) increased rehabilitation intensity, and (3) frequent feedback to patients on their effort and progress. Measurements Therapy intensity: assessment of patient active time in therapy sessions. Therapy engagement: Rehabilitation Participation Scale. Functional and performance outcomes: Barthel Index, gait speed, and six-minute walk. Results Participants randomized to Enhanced Medical Rehabilitation had higher intensity therapy and were more engaged in their rehabilitation sessions; they had more improvement in gait speed (improving from 0.08 to 0.38 meter/sec vs. 0.08 to 0.22 in standard of care,p=0.003) and six-minute walk (from 73 to 266 feet vs. 40 to 94 feet in standard of care, p=0.026), with a trend for better improvement of Barthel Index (+43 points vs. 26 points in standard of care, p=0.087), compared to participants randomized to standard
