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

  6. Acute leukemia in early childhood

    2007-06-01

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

  7. The acute abdomen in childhood

    International Nuclear Information System (INIS)

    The acute abdomen in childhood demands early diagnosis for the sake of appropriate and early therapy. A high number of differential diagnosis in the assessment of acute abdominal pain and problems, as well as different causes of diseases in different age of the children, make a partition with respect to the age of the children considerable. A partition in diseases, which are leading to acute abdominal pain in neonates, in toddlers and small infants and in schoolchildren makes sense. In older schoolchildren and adolescents also diseases of the grown up generation are possible as a cause of acute abdominal pain. The lack of compliance (cooperation and communication) in small children obstructs clinical and radiological assessment and elucidates the necessity of knowledge of causes of acute abdominal pain as much as possible. A lot of patience and experience are mandatory in the evaluation of small children and therefore make a dedicated, trained and experienced stuff necessary. A dedicated paediatric radiologist will find a safe and proper technique, and in cooperation with the referring clinician the necessary decision for therapy will be made. (orig.)

  8. Acute childhood leukemia: Nursing care

    International Nuclear Information System (INIS)

    Modern therapy for childhood acute leukemia has provided a dramatically improved prognosis over that of just 30 years ago. In the early 1960's survival rates for acute lymphocytic leukemia (ALL) and acute myelogenous leukemia (AML) were 4% and 3%, respectively. By the 1980's survival rates had risen to 72% for all and 25% to 40% for AML. Today, a diagnosis of all carries an 80% survival rate and as high as a 90% survival rate for some low-risk subtypes. Such high cure rates depend on intense and complex, multimodal therapeutic protocols. Therefore, nursing care of the child with acute leukemia must meet the demands of complicated medical therapies and balance those with the needs of a sick child and their concerned family. An understanding of disease process and principles of medical management guide appropriate and effective nursing interventions. Leukemia is a malignant disorder of the blood and blood- forming organs (bone marrow, lymph nodes and spleen). Most believe that acute leukemia results from a malignant transformation of a single early haematopoietic stem cell that is capable of indefinite self-renewal. These immature cells of blasts do not respond to normal physiologic stimuli for differentiation and gradually become the predominant cell in the bone marrow

    Benign focal epileptiform discharge of childhood (BFEDC) is an age-dependent pattern determined in electroencephalograms (EEGs), which is associated with idiopathic benign focal epilepsy (BFE). Studies of BFE revealed symptomatic phenocopies in patients with cerebral struc- tural abnormalities in such conditions as infantile cerebral palsy and malformations. Some arguments against the «benign» nature of BFEDC are presented, since BFEDC may impair various cognitive functions and behavior (e.g....

    2014-05-01

    Full Text Available Background: Acute retinal necrosis (ARN is a viral syndrome consisting of uveitis/vitritis, occlusive vasculitis and peripheral necrosis. Few incidents are reported in children. The etiology is reactivated herpes simplex virus (HSV or varicella-zoster virus (VZV. Treatment with acyclovir is often used. The administration of oral glucocorticosteroids is of unproven benefit. Prognosis is variable but poor. Methods: Three weeks after contracting mild chickenpox, a healthy 4-year-old girl developed blurred vision in her right eye. Severely reduced visual acuity was noted, together with anterior uveitis, ‘mutton-fat' precipitates and vitral flare. Retinal vasculitis with necrosis was present. Serology for toxoplasma, cytomegalovirus and HIV was negative, while HSV and VZV IgG antibodies were positive. She was treated with 30 mg/kg of intravenous methylprednisolone (3 days, 30 mg of oral prednisone (3 days, and tapering for 8 weeks. Intravenous acyclovir was given for 10 days, followed by oral acyclovir for 4 months. Aspirin (100 mg/day was given for 4 months. Results: At 12 months, the girl felt good. Her right eye acuity was 6/9, with an intraocular pressure of 17 mm Hg. The peripheral retina showed scarring but no detachment. Conclusions: This is the first report of a once-daily high-dose methylprednisolone pulse therapy in one of the youngest known ARN cases. Pulsed steroid therapy was based on its known effectiveness in vasculitis, which is the main pathophysiology in ARN. There was no evidence of steroid-related viral over-replication. Our case achieved an excellent clinical and ophthalmic recovery in spite of the poor prognosis. The positive result of this case report provides a basis for further evaluation of high-dose steroid pulse therapy in ARN.

    Full Text Available A Pession, R Masetti, K Kleinschmidt, A MartoniPediatric Oncology and Hematology “Lalla Seràgnoli”, University of Bologna, ItalyAbstract: A second-generation of purine nucleoside analogs, starting with clofarabine, has been developed in the course of the search for new therapeutic agents for acute childhood leukemia, especially for refractory or relapsed disease. Clofarabine is a hybrid of fludarabine and cladribine, and has shown to have antileukemic activity in acute lymphoblastic leukemia as well as in myeloid disorders. As the only new antileukemic chemotherapeutic agent to enter clinical use in the last 10 years, clofarabine was approved as an orphan drug with the primary indication of use in pediatric patients. Toxicity has been tolerable in a heavily pretreated patient population, and clofarabine has been demonstrated to be safe, both as a single agent and in combination therapies. Liver dysfunction has been the most frequently observed adverse event, but this is generally reversible. Numerous Phase I and II trials have recently been conducted, and are still ongoing in an effort to find the optimal role for clofarabine in various treatment strategies. Concomitant use of clofarabine, cytarabine, and etoposide was confirmed to be safe and effective in two independent trials. Based on the promising results when used as a salvage regimen, clofarabine is now being investigated for its potential to become part of frontline protocols.Keywords: clofarabine, pediatric acute lymphoblastic leukemia, pediatric acute myeloid leukemia

    A seventy two year old man presented to the Emergency Department with clinical features of colonic obstruction. Subsequent radiological investigations confirmed this impression and revealed the aetiology to be compression of the sigmoid colon against the sacrum by a massively distended urinary bladder. Chronic urinary retention due to benign prostatic hypertrophy is an extremely unusual cause of large bowel obstruction. Little in this patient\\'s clinical findings suggested this aetiology. We reviewed the literature in this area and highlight the benefits of CT scanning over contrast studies.

    2012-01-17

    Most studies about cognitive functions in children with benign childhood epilepsy with centrotemporal spikes (BCECTS) have been conducted with alphabetic writing background subjects, however deficits observed might therefore potentially differ in a Chinese language environment. This study was designed to evaluate the intelligence quotient (IQ) profiles, especially the language abilities, in Chinese children with BCECTS and to investigate whether there is a relationship between clinical factors and disorders of cognitive functions. There are selective cognitive deficits in Chinese children with BCECTS, although the Full Scale Intelligence Quotient is within the normal range. There was a correlation between spike wave index (SWI) and language deficits in children with BCECTS, but the deficits are not dependent on age of onset, disease course, seizure frequency, spike location or seizure type. It is important that children with typical BCECTS undergo regular clinical investigations about language performance in order to start necessary interventions as early as possible. PMID:22020258

    1983-07-01

    To investigate the relationship of irradiation during infancy and childhood to the subsequent development of carcinoma of the breast, 996 eligible patients were studied at Evanston Hospital, Evanston, Illinois, and Northwestern Memorial Hospital, Chicago. This was a case-control study, with those in the control group being selected from concurrent hospital admissions for nonmalignant surgical conditions. A second group consisting of those with benign biopsy results was also studied. The Mantel-Haenszel method of analysis, controlling for age and race, was used to estimate the approximate relative risk of carcinoma of the breast in the irradiated group compared with that for the nonirradiated group. The type of radiation history included radiotherapy for mastitis or enlarged thymus (nine patients), irradiation of the head and neck (69 patients), diagnostic fluoroscopies (ten patients) and miscellaneous irradiation (52 patients) for bursitis, eczema or keloid. Based upon the data obtained from the results of this study and its analysis, we conclude that there is little evidence of increased risk of carcinoma of the breast after irradiation about the head, neck and chest areas for benign conditions in the population being studied herein. Such a risk, if indeed it exists at all for this population, is estimated to be about 10 per cent.

    Full Text Available Benign focal epileptiform discharge of childhood (BFEDC is an age-dependent pattern determined in electroencephalograms (EEGs, which is associated with idiopathic benign focal epilepsy (BFE. Studies of BFE revealed symptomatic phenocopies in patients with cerebral struc- tural abnormalities in such conditions as infantile cerebral palsy and malformations. Some arguments against the «benign» nature of BFEDC are presented, since BFEDC may impair various cognitive functions and behavior (e.g., cause epileptic encephalophathies. Objective. To determine the clinical and neurophysiological features of epileptic syndromes associated with prolonged epileptiform activity during sleep in children and adolescents, as well as approaches to rational therapy. Patients and Methods. A total of 1862 children aged 2–18 admitted to the specialized Department of Psychoneurology of the Voronezh Regional Children Clinical Hospital No 1 in 2004–2007, who had epileptic seizures and non-epileptic neurological disorders, were exam- ined. The children underwent assessment of the neurological status, neuropsychological assessment, and video-EEG monitoring. The spike- wave index (SWI was calculated and magnetic resonance imaging (MRI of the brain was performed to register the epileptiform activity during sleep. Results and Discussion. It was demonstrated that when ISW of BFEDC patterns is >30%, evolution into epileptic encephalopathy was observed in 66% of patients (including epilepsy with electrical status epilepticus in sleep in 49% of patients and cognitive epileptiform disinte- gration in 17% of patients. The results prove the justification of prescribing antiepileptic drugs to patients with SWI ≥30% even if they have no epileptic seizures. Duo-therapy with valproate and ethosuximide or levetiracetam is most the effective therapy. Further prospective studies for children with BFEDC will give new insight into this area.

    2009-01-01

    Traditionally, response to treatment in hematological malignancies is evaluated by light microscopy of bone marrow (BM) smears, but due to more effective therapies more sensitive methods are needed. Today, detection of minimal residual disease (MRD) using immunological and molecular techniques can be 100 times more sensitive than morphology. The main aim of this thesis was to compare and evaluate three currently available MRD methods in childhood acute lymphoblastic leukemia (ALL): (i) real-t...

    Full Text Available Acute erythroid leukemia in children is very rare. Here is a case of erythroleukemia in a child of age 1.5 years, which was diagnosed on peripheral smear, bone marrow examination, cytochemistry but was confirmed on immunophenotyping. CD45 versus side scatter demonstrated blast population (29% expressing CD45 of variable intensity (dim to negative. The myeloid nature of blast population showed bright expression of cytoplasmic myeloperoxidase (MPO, heterogenous positivity of CD117 and dim expression of CD13, CD33. These blasts also showed bright positivity for CD71 which showed erythroid nature of blasts. Flow cytometry can be comprehensive enough to completely subtype cases of leukemias/myelodysplastic syndromes, polycythemia rubra vera, non-neoplastic conditions like reactive erythroid hyperplasia following immunosuppressive therapy or viral infections or nutritional deficiencies, unlyzed RBCs or thrombocytosis which may mimic acute erythroid leukemia on flow cytometry.

    Children with acute severe asthma exacerbation are at risk of developing respiratory failure. Moreover, conventional aggressive management might be futile in acute severe asthma requiring intubation and invasive ventilation. The aim of this review is to detail evidence on the use of ketamine in childhood asthma exacerbations. A search of the MEDLINE, EMBASE, and Cochrane databases was performed, using different combinations of the following terms: ketamine, asthma, use, exacerbation, and childhood. In addition, we searched the references of the identified articles for additional articles. We then reviewed titles and included studies that were relevant to the topic of interest. Finally, the search was limited to studies published in English and Spanish from 1918 to June 2015. Due to the scarcity in the literature, we included all published articles. The literature reports conflicting results of ketamine use for acute severe asthma in children. Taking into consideration the relatively good safety profile of the drug, ketamine might be a reasonable option in the management of acute severe asthma in children who fail to respond to standard therapy. Furthermore, pediatricians and pediatric emergency clinicians administering ketamine should be knowledgeable about the unique actions of this drug and its potential side effects. PMID:26955277

    2011-01-01

    Full Text Available The role of angiogenesis in acute leukaemia has been discussed since the cloning of the gene of vascular endothelial growth factor (VEGF from the acute myelogenous leukemia cell line (HL60 and, thereafter, when the first studies reported increased bone marrow vascularity and elevation of angiogenic cytokines in acute lymphoblastic leukaemia (ALL. VEGF and basic fibroblast growth factor (bFGF are the major proangiogenic cytokines that have been studied, and evaluation of their prognostic impact in childhood ALL has been reported in several studies, though with controversial results. The antiangiogenic response, contributing to the angiogenic balance, has scarcely been reported. The origin of the factors, their prognostic value, and their relevance as good markers of what really happens in the bone marrow are discussed in this paper. The place of antiangiogenic drugs in ALL has to be defined in the global treatment strategy.

    Full Text Available The aim of this study was to investigate distribution of immunophenotypic and cytogenetic features of childhood acute leukemia (AL in the cohort of 239 newly diagnosed patients registered at the leading pediatric oncohematology center in the country during a six-year period (1996-2002. With approximately 60-70% of all childhood AL cases in Serbia and Montenegro being diagnosed and treated in this institution the used data represent a valid research sample to draw conclusions for entire country. On the basis of five phenotypic markers, the distribution of immunological subtypes was as follows: 169 (70.7% expressed B-cell marker CD19 (137 were CD10 positive and 32 CD10 negative, 37 (15.5% belonged to T-lineage acute lymphoblastic leukemia (T-ALL (cyCD3 positive, and 33 (13.8% were acute myeloblastic leukemia (AML (CD13 positive and/or CD33 positive in the absence of lymphoid-associated antigens. The ratio of males and females was 1.5:1. Most of the cases were between the ages of 2 and 4, and were predominantly B-lineage acute lymphoblastic leukemia (B-ALL cases. Another peak of age distribution was observed at the age of 7. The frequency of T-ALL (18% of ALL was similar to that reported for Mediterranean countries: France (19.4%, Greece (28.1%, Southern Italy (28.3%, and Bulgaria (28.0%. Cytogenetic analyses were performed in 193 patients: 164 ALL and 29 AML. Normal karyotype was found in 57% of ALL and in 55% of AML patients, while cytogenetic abnormalities including structural, numerical, and complex chromosomal rearrangements were found in 43% of ALL and in 45% of AML patients. Our results represent a contribution to epidemiological aspects of childhood leukemia studies.

    Full Text Available ntroduction: Many people suffer from vertigo. Its origin in 85% of cases is otological while in 15% is central etiology. Benign paroxysmal positional vertigo (BPPV is the most common cause of the true vertigo. In this research we evaluated the risk factors of acute attack of BPPV. Materials and Methods: This study was performed on 322 patients, presenting with BPPV. Diagnosis was confirmed by history and Dix-Hallpike manoeuvre. The underling risk factors documented carefully. Data analyzed by SPSS and K.square test. Results: Number of 321 patients (including 201 females and 120 males with BPPV included in our study. Their average age was 41. They showed symptoms for 1 month to 15 years (mean 8 months. Emotional stress was positive in 34% and trauma was the only risk factor in 8.12% patients. Ear surgery and prolonged journey were respectively the main risk factors in 7.2 and 12.8% of patients. Conclusion: The confirmed risk factors of acute attack of BPPV were as trauma, major surgery and ear surgery especially stapedotomy, vestibular  neuronitis and prolonged bedrestriction. Meniere was not considered as risk factor. In our study the psychological conflict was the major risk factor for BPPV. Other new risk factors which introduced for first time included; sleep disorder, fatigue, professional sport, starving and prolonged journey.

  19. Aetiology of childhood acute leukaemias: Current status of knowledge

    International Nuclear Information System (INIS)

    Acute leukaemia is a consequence of malignant transformation of a haematopoietic progenitor cell. Molecular studies have revealed a prenatal origin of many childhood leukaemias. According to current models, a pre-leukaemic stem cell clone is generated by a first mutation in utero which, in a minority of children, progresses to leukaemia after receiving further postnatal genetic hits. The nature of pre- and postnatal events involved in leukemogenesis in children is not well understood. Although genetic predisposition and specific environmental exposures may account for individual cases, the bulk of childhood leukaemia cannot be explained by any of these factors. The higher incidence of the most common leukaemia subtype in affluent societies, as well as the age peak between 2-5 y, suggest a contributory role of socioeconomic factors. An abnormal immune response during delayed exposure to common infections provides a plausible mechanism for malignant progression of pre-leukaemic clones in a subgroup of children. As highlighted in this review, a common cause for all types and subtypes of childhood leukaemia is highly unlikely. Deeper insights into the pathogenesis of childhood leukaemia will rely on large-scale and combined epidemiological and bio-molecular studies. (authors)

    2013-06-01

    Full Text Available This study evaluated the sequential motor manual actions in children with benign focal epilepsy of childhood with centrotemporal spikes (BECTS and compares the results with matched control group, through the application of Luria's fist-edge-palm test. The children with BECTS underwent interictal single photon emission computed tomography (SPECT and School Performance Test (SPT. Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.

    The goal of our project is to develop a unique ligand-conjugated nanoparticle (NP) therapy against childhood acute lymphoblastic leukemia (ALL). LLP2A, discovered by Dr. Kit Lam, is a high-affinity and high-specificity peptidomimetic ligand against an activated α4β1 integrin. Our study using 11 fresh primary ALL samples (10 precursor B ALL and 1 T ALL) showed that childhood ALL cells expressed activated α4β1 integrin and bound to LLP2A. Normal hematopoietic cells such as activated lymphocytes and monocytes expressed activated α4β1 integrin; however, normal hematopoietic stem cells showed low expression of α4β1 integrin. Therefore, we believe that LLP2A can be used as a targeted therapy for childhood ALL. The Lam lab has developed novel telodendrimer-based nanoparticles (NPs) which can carry drugs efficiently. We have also developed a human leukemia mouse model using immunodeficient NOD/SCID/IL2Rγ null mice engrafted with primary childhood ALL cells from our patients. LLP2A-conjugated NPs will be evaluated both in vitro and in vivo using primary leukemia cells and this mouse model. NPs will be loaded first with DiD near infra-red dye, and then with the chemotherapeutic agents daunorubicin or vincristine. Both drugs are mainstays of current chemotherapy for childhood ALL. Targeting properties of LLP2A-conjugated NPs will be evaluated by fluorescent microscopy, flow cytometry, MTS assay, and mouse survival after treatment. We expect that LLP2A-conjugated NPs will be preferentially delivered and endocytosed to leukemia cells as an effective targeted therapy.

    Full Text Available Specific cognitive deficits have been identified in children with epilepsy irrespective of results on intelligence tests. Memory deficits are traditionally attributed to temporal lobe epilepsy, whereas the impact of frontal lobe epilepsy on memory functions has remained controversial. The aim of this study was the examination of memory abilities in other childhood common epilepsy syndromes (frontal lobe epilepsy (FLE, childhood absence epilepsy (CAE, and benign epilepsy with centrotemporal spikes (BECTS and the influence of epilepsy-related variables. Memory was examined in 90 children with epilepsy (each epilepsy group consisted of 30 children, aged 6–15, and compared with 30 control children. Children with FLE showed significant deficits in verbal and visual memory. In addition, type of epilepsy, earlier age at epilepsy onset, and longer active duration of epilepsy were associated with memory problems. Seizure frequency and treatment, however, did not influence memory performance. This study indicates that children with FLE show greater risk of developing memory deficits than children with CAE or BECTS, thus highlighting the importance of assessing also memory functions in frontal lobe epilepsy.

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

  5. Side effects of treatment in childhood acute leukemia, 2

    International Nuclear Information System (INIS)

    We evaluated delayed neurotoxicities in treatment of childhood acute leukemia. Of 28 patients treated over 2 years who were examined on computed tomography of brain scans, 7 patients had abnormal findings. These abnormalities included two cases of leukoencephalopathy, three cases of intracranial calcifications, and two of ventricular dilatation. These patients were under 6 years old at the onset of disease, especially under 3 years old. Also, delayed neurotoxicities developed after relapse of leukemia, especially CNS relapse. It was considered that these were caused by cranial irradiation, intravenous methotrexate injection, intrathecal methotrexate, and sometimes high-dose Ara-C therapy, etc. Most of the cases of leukoencephalopathy were associated with treatment of intermediate-dose or high-dose methotrexate after relapse. These abnormalities must be carefully considered in the treatment of younger children with leukemia and patients with relapse. (author)

    Viral gastroenteritis is the most frequent cause of acute gastroenteritis (AGE) of childhood. The aim of this study was to determine the prevalence of viral agents including astrovirus, rotavirus, adenovirus, enterovirus, norovirus, parechovirus, Aichivirus and sapovirus in children with AGE in a pediatric Turkish population. Fecal specimens of 240 children with AGE were investigated by polymerase chain reaction, and viral agents were identified in 131 (54.6%) samples. The distribution of viral agents was as follows: 56 (42.8%) norovirus, 44 (33.6%) rotavirus, 29 (22.1%) enterovirus, 21 (16.0%) adenovirus, 21 (16.0%) parechovirus, 5 (3.8%) sapovirus and 1 (0.8%) Aichivirus. Single and multiple viral agents were detected in 38.8% and 15.8% of patients, respectively. The duration of hospitalization was longer in children with multiple viral agents than in those infected with a single viral agent (p<0.001). While the highest rate of rotavirus infection was detected in winter, the highest rate of norovirus was found in the summer. In conclusion, norovirus and rotavirus are the most frequent causes of childhood AGE in our country. PMID:26613223

    2016-04-01

    Dexamethasone is a key component in the treatment of childhood acute lymphoblastic leukaemia (ALL). Despite playing a key role in the improved survival of ALL over several decades, intensification of dexamethasone therapy has also contributed to the increased toxicity associated with treatment, which is now seen to be at unacceptable levels given the favourable disease prognosis. Therefore the focus for treatment is now shifting towards reducing toxicity whilst maintaining current survival rates. As approximately 50% of patients were successfully treated on less intensive protocols of the 1980s, it has been questioned whether therapy intensification is necessary in all patients. Furthermore, there remains a subset of children who are still not cured of their disease. New strategies are therefore needed to identify patients who could benefit from dose reduction or intensification. However, adjusting a potentially life threatening therapy is a challenging task, particularly given the heterogeneous nature of ALL. This review focuses on the potential for patient stratification based on our current knowledge of dexamethasone pharmacokinetics, pharmacogenetics and the action of dexamethasone at the cellular level. A carefully designed, combined approach is needed if we are to achieve the aim of improved personalization of dexamethasone therapy for future patients. PMID:26729065

    Acute lymphoblastic leukemia is the major pediatric cancer in developed countries. To date most association studies of acute lymphoblastic leukemia have been based on the candidate gene approach and have evaluated a restricted number of polymorphisms. Such studies have served to highlight difficulties in conducting statistically and methodologically rigorous investigations into acute lymphoblastic leukemia risk. Recent genome-wide association studies of childhood acute lymphoblastic leukemia have provided robust evidence that common variation at four genetic loci confers a modest increase in risk. The accumulated experience to date and relative lack of success of initial efforts to identify novel acute lymphoblastic leukemia predisposition loci emphasize the need for alternative study designs and methods. The International Childhood Acute Lymphoblastic Leukaemia Genetics Consortium includes 12 research groups in Europe, Asia, the Middle East and the Americas engaged in studying the genetics of acute lymphoblastic leukemia. The initial goal of this consortium is to identify and characterize low-penetrance susceptibility variants for acute lymphoblastic leukemia through association-based analyses. Efforts to develop genome-wide association studies of acute lymphoblastic leukemia, in terms of both sample size and single nucleotide polymorphism coverage, and to increase the number of single nucleotide polymorphisms taken forward to large-scale replication should lead to the identification of additional novel risk variants for acute lymphoblastic leukemia. Ethnic differences in the risk of acute lymphoblastic leukemia are well recognized and thus in assessing the interplay between inherited and non-genetic risk factors, analyses using different population cohorts with different incidence rates are likely to be highly informative. Given that the frequency of many acute lymphoblastic leukemia subgroups is small, identifying differential effects will realistically only be

  19. Quantitative assessments of indoor air pollution and the risk of childhood acute leukemia in Shanghai

    International Nuclear Information System (INIS)

    We investigated the association between indoor air pollutants and childhood acute leukemia (AL). A total of 105 newly diagnosed cases and 105 1:1 gender-, age-, and hospital-matched controls were included. Measurements of indoor pollutants (including nitrogen dioxide (NO2) and 17 types of volatile organic compounds (VOCs)) were taken with diffusive samplers for 64 pairs of cases and controls. Higher concentrations of NO2 and almost half of VOCs were observed in the cases than in the controls and were associated with the increased risk of childhood AL. The use of synthetic materials for wall decoration and furniture in bedroom was related to the risk of childhood AL. Renovating the house in the last 5 years, changing furniture in the last 5 years, closing the doors and windows overnight in the winter and/or summer, paternal smoking history and outdoor pollutants affected VOC concentrations. Our results support the association between childhood AL and indoor air pollution. - Highlights: • We firstly assessed the effects of indoor air pollution on childhood AL in China. • Indoor air pollutants were assessed by questionnaire and quantitative measurements. • NO2 and 17 types of VOCs were measured in bedrooms of both cases and controls. • Higher concentrations of indoor air pollutants increased the risk of childhood AL. • Indoor behavioral factors and outdoor pollution might affect indoor air pollution. - Higher concentrations of indoor air pollutants were related to an elevated risk of childhood AL

    Acute necrotizing encephalopathy of childhood (ANEC) is a disease entity seen nearly exclusively in East Asian children that is characterized by multifocal, symmetric lesions involving the thalami, brainstem, cerebellum, and white matter. We present a child who developed dramatic neurologic symptoms following a viral prodrome. Serial MRI examinations demonstrated characteristic lesions of ANEC, while laboratory analyses revealed evidence of acute infection with human herpesvirus-6 (HHV-6). We highlight the MRI findings in both the acute and convalescent phases of ANEC, discuss the implications of neuroimaging on the child's clinical course, and emphasize the integral role of the radiologist in correctly diagnosing this rare disease.

  2. Prevalence of benign and malignant thyroid nodules in patients with previous history of radiotherapy for Tinea capitis in childhood (in khorosan province)

    International Nuclear Information System (INIS)

    Increased prevalence of thyroid cancer was noted in patients with previous history of radiotherapy of the head and neck region in childhood. According to previous research, radiotherapy for Ti nia capitis was using up to 30 years ago in Khorasan Province. This study tries to evaluate prevalence of benign and malignant thyroid nodules and detect and treat these patients earlier to prevent more complications and increased cost. Methods and patients: Using mass media, we recalled all patients with history of radiotherapy for Tinea capitis in childhood. A questionnaire was filled for each patient and thyroid examination, thyroid scan and thyroid sonography were performed. Fine needle aspiration biopsy (FNAB) was done if a thyroid nodule larger than 1 cm was palpable. Serum TSH was measured in all patients. Also thyroid surgery was recommended for all patients with thyroid nodules more than 1 cm. A control group was defined from a group of patients who referred for non thyroidal sonography to radiology department of Ghaem hospital. These patients also were evaluated by clinical examination and thyroid sonography. Results: We studied 180 patients with mean age of 47.7 years and 127 age and sex m etched controls. Thyroid nodules was palpated in 45.5% of patients and 7% of controls (P0.01). The mean largest diameter of nodules were 24.8 mm in patients and 10.8 mm in control group (P<0.001). 75% of patients were agreed with FNAB and 5% of them had suspicious cytology results. No suspicious or malignant results was noted in control group. Twenty seven patients (33.7%) were operated. Pathological results were benign in 89.9% and malignant in 1% of patients. His study showed that thyroid nodules and thyroid neo plasma were significantly more larger in the patients group. Thyroid neoplasm were more frequent in younger patients with latent thyroid (from radiotherapy) of less than 40 years, so aggressive evaluation is recommended in these group

    Recurrent episodes of life-threatening myoglobinuria in childhood are caused by inborn errors of glycogenolysis, mitochondrial fatty acid beta-oxidation, and oxidative phosphorylation. Nonetheless, approximately half of the patients do not suffer from a defect in any of these pathways. Using homozygosity mapping, we identified six deleterious mutations in the LPIN1 gene in patients who presented at 2-7 years of age with recurrent, massive rhabdomyolysis. The LPIN1 gene encodes the muscle-specific phosphatidic acid phosphatase, a key enzyme in triglyceride and membrane phospholipid biosynthesis. Of six individuals who developed statin-induced myopathy, one was a carrier for Glu769Gly, a pathogenic mutation in the LPIN1 gene. Analysis of phospholipid content disclosed accumulation of phosphatidic acid and lysophospholipids in muscle tissue of the more severe genotype. Mutations in the LPIN1 gene cause recurrent rhabdomyolysis in childhood, and a carrier state may predispose for statin-induced myopathy. PMID:18817903

    2014-03-01

    Whereas most research on acute myocardial infarction (AMI) has focused on more proximal influences, such as adult health behaviors, the present study examines the early origins of AMI. Longitudinal data were drawn from the National Survey of Midlife Development in the United States (N = 3032), a nationally representative survey of men and women aged 25-74, which spans from 1995 to 2005. A series of event history analyses modeling age of first AMI investigated the direct effects of accumulated and separate domains of childhood misfortune as well as the mediating effects of adult health lifestyle and psychosocial factors. Findings reveal that accumulated childhood misfortune and child maltreatment increased AMI risk, net of several adult covariates, including family history of AMI. Smoking fully mediated the effects of both accumulated childhood misfortune and child maltreatment. These findings reveal the importance of the early origins of AMI and health behaviors as mediating factors. PMID:24581071

    Acute leukemia is the most common type of childhood and adolescence cancer, characterized by clonal proliferation of variably differentiated myeloid or lymphoid precursors. Recent insights into the molecular pathogenesis of leukemia have shown that epigenetic modifications, such as deacetylation of histones and DNA methylation, play crucial roles in leukemogenesis, by transcriptional silencing of critical genes. Histone deacetylases (HDACs) are potential targets in the treatment of leukaemia,...

    Full Text Available Abstract Background Acute diarrhoea is a major cause of childhood morbidity and mortality in sub-Saharan Africa. Its microbiological causes and clinico-epidemiological aspects were examined during the dry season 2005/6 in Tamale, urban northern Ghana. Methods Stool specimens of 243 children with acute diarrhoea and of 124 control children were collected. Patients were clinically examined, and malaria and anaemia were assessed. Rota-, astro-, noro- and adenoviruses were identified by (RT- PCR assays. Intestinal parasites were diagnosed by microscopy, stool antigen assays and PCR, and bacteria by culturing methods. Results Watery stools, fever, weakness, and sunken eyes were the most common symptoms in patients (mean age, 10 months. Malaria occurred in 15% and anaemia in 91%; underweight (22% and wasting (19% were frequent. Intestinal micro-organisms were isolated from 77% of patients and 53% of controls (P P = 0.02. Conclusion Rotavirus-infection is the predominant cause of acute childhood diarrhoea in urban northern Ghana. The abundance of putative enteropathogens among controls may indicate prolonged excretion or limited pathogenicity. In this population with a high burden of diarrhoeal and other diseases, sanitation, health education, and rotavirus-vaccination can be expected to have substantial impact on childhood morbidity.

  17. The diagnosis and management of acute childhood illness: is there a role for health visitors?

    2000-12-01

    Much of the published literature on nurse practitioners relates to nurses with backgrounds, training and nursing experience other than health visiting. Health visitors however may be ideally placed to develop their role in the identification and management of acute childhood illness, and such a development may benefit patients, the health service and health visitors themselves. This study examines the current practice and attitudes of heath visitors in identifying and managing acute childhood illness using a postal questionnaire survey in one community National Health Service (NHS) Trust. The majority of responding health visitors reported that they were already identifying and advising on a range of acute childhood illnesses. Their confidence in undertaking these activities varied by condition. They were less confident in identifying and advising on conditions requiring the use of diagnostic equipment, viral illnesses which are becoming increasingly rare, and those with potentially serious outcomes. More knowledge and more training were seen as methods for increasing confidence. Most health visitors could see advantages in taking on this role; almost two thirds felt it would become part of the role of the health visitor in the future and a high level of interest was expressed in developing such a role.

    Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy, and until recently prophylactic cranial radiotherapy (CRT) was important for achieving long-term survival. Hypothalamic-pituitary hormone insufficiency is a well-recognized consequence of CRT for childhood cancer. Another problem is increased cardiovascular risk, which has been shown in long-term survivors of other childhood cancers. In the only previously reported study on cardiovascular risk after childhood ALL, obesity and dyslipidemia were recorded in a small subgroup treated with CRT, compared with patients treated with chemotherapy. The mechanisms behind the increase in cardiovascular risk in survivors of childhood cancer are not clarified. The aim of the present study was to elucidate mechanisms of increased cardiovascular risk in former childhood ALL patients. A group of 44 ALL survivors (23 males, median age 25 yr, range 19-32 yr at the time of study) treated with CRT (median 24 Gy, 18-30 Gy) at a median age of 5 yr (1-18 yr) and chemotherapy were investigated for prevalence of GH deficiency and cardiovascular risk factors. Comparison was made with controls randomly selected from the general population and individually matched for sex, age, smoking habits, and residence. All patients and controls underwent a GHRH-arginine test, and patients with a peak GH 3.9 microg/liter or greater were further investigated with an additional insulin tolerance test. Significantly higher plasma levels of insulin (P = 0.002), blood glucose (P = 0.01), and serum levels of low-density lipoprotein cholesterol, apolipoprotein (Apo) B, triglycerides, fibrinogen, and leptin (all P childhood ALL patients, a significant increase in cardiovascular risk factors was recorded. We suggest that GH deficiency, induced by CRT, is a primary cause for this because strong correlations between the stimulated GH peak and several of the cardiovascular risk factors were observed.

  19. Cranial radiation in childhood acute lymphocytic leukemia. Neuropsychologic sequelae

    International Nuclear Information System (INIS)

    A battery of neuropsychologic tests was administered ''blindly'' to 18 children with acute lymphocytic leukemia (ALL) who had been randomly assigned to treatment regimens with or without cranial radiation. These children were all in complete continuous remission for more than 3 1/2 years and were no longer receiving therapy. The results indicated no substantial differences between groups as a function of radiation therapy. However, decreased neuropsychologic performance was found when the entire sample was compared with population norms. These data do not support the hypothesis that cranial radiation therapy is responsible for the neuropsychologic sequelae seen in these survivors of ALL. Post hoc multiple regression analysis indicated that parental education levels accounted for more of the neuropsychologic variability seen in these children than other factors such as age at diagnosis, type of therapy, or sex of child

  20. Side effect of cranial radiation in childhood acute leukemia, 1

    International Nuclear Information System (INIS)

    We examined the somnolence syndrome, which is one of the side effects of cranial irradiation. Out of 53 patients in acute leukemia who had received cranial irradiation, nine patients (17%) developed the somnolence syndrome. Patients with the somnolence syndrome showed slow waves on EEG. Some patients had ventricular dilatation and widening of sulci before cranial irradiation on CT findings, but these findings improved after cranial irradiation. Out of nine cases with the somnolence syndrome, 6 patients survived and did not experience difficulties in school. But one patient showed calcification on CT brain scan. It is considered that the cause of the somnolence syndrome is a trasient inhibition of myelin synthesis and most patients improved without serious sequelae. It is necessary to follow up many cases of somnolence syndrome. (author)

    Full Text Available Acute diarrhea remains a major cause of morbidity and mortality in children. Since the introduction of oral rehydration salts (ORS mortality has dropped to less than 50% worldwide. Low osmolarity ORS improved the outcome and reduced the hospitalization further. Zinc difficiency has been found to be associated with severe episodes of acute diarrhea. Zinc supplement in developing countries did reduce the incidence and prevalence of diarrhea. In addition, Zinc supplement significantly reduced the severity of diarrhea and duration of the episode. In the Americas and Europe, Rota virus vaccine was 90% effective in preventing severe episodes of severe rotavirus gastroenteritis. This review concludes that low osmolarilty ORS, zinc supplementation and rotavirus vaccine are major factors in reducing the morbidity, mortality and hospitalization resulting from to acute gastroenteritis in childhood.

    International Nuclear Information System (INIS)

    From 1970 through 1979, 22 children with acute childhood leukemia and in remimmion were treated with preventive central nervous system (CNS) irradiation and simultaneous intrathecal methotrexate. A minimum follow-up duration was five months. Of 22 cases, 20 were acute lymphocytic leukemia (ALL) and 2 were acute myelocytic leukemia (ALL). Five-year cumulative survival rate and five-year relapse free survival rate of ALL case were 48% and 46% respectively. Nor neurological disorders after the prophylactic combined therapy were recognized clinically by the time when this follow-up was finished. Of 15 children with ALL who were followed by computed tomography of the brain, 5(33%) had abnormal findings. Dilatation of the ventricles were seen in 3 cases, and low density areas of the occipital regions in 2 cases. (author)

  3. Outcome following late marrow relapse in childhood acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    Thirty-four children with acute lymphoblastic leukemia, who developed bone marrow relapse after treatment was electively stopped, received reinduction, consolidation, continuing therapy, and intrathecal (IT) methotrexate (MTX). Sixteen children who relapsed within six months of stopping treatment had a median second-remission duration of 26 weeks; all next relapses occurred in the bone marrow. In 18 children who relapsed later, the median duration of second remission was in excess of two years, but after a minimum of four years follow-up, 16 patients have so far relapsed again (six in the CNS). CNS relapse occurred as a next event in four of 17 children who received five IT MTX injections only and in two of 14 children who received additional regular IT MTX. Although children with late marrow relapses may achieve long second remissions, their long-term out-look is poor, and regular IT MTX does not afford adequate CNS prophylaxis. It remains to be seen whether more intensive chemotherapy, including high-dose chemoradiotherapy and bone marrow transplantation, will improve the prognosis in this group of patients

    Many children experiencing acute asthmatic episodes have chest radiographs, which may show lung hyperinflation, hypoinflation, or normal inflation. Lung hypoinflation may be a sign of respiratory fatigue and poor prognosis. To compare the clinical course in children with asthma according to the degree of lung inflation on chest radiographs. We conducted a retrospective study during a 24-month period (from July 1999 to July 2001) of children aged 0-17 years, who presented to a pediatric emergency department or outpatient clinic with an asthma exacerbation. Chest radiographs obtained at presentation were reviewed independently by three pediatric radiologists who were blinded to the admission status of the patient. The correlation between hypoinflation and hospital admission was assessed in three age groups: 0-2 years, 3-5 years, and 6-17 years. Hypoinflation on chest radiographs was significantly correlated with hospital admission for children aged 6-17 years (odds ratio 16.00, 95% confidence interval 1.89-135.43). The inter-reader agreement for interpretation of these radiographs was strong, with a kappa score of 0.76. Hypoinflation was not correlated with admission in younger children. Lung hypoinflation is associated with a greater likelihood of hospital admission in children aged 6 years or older. Therefore, hypoinflation was a poor prognostic sign and may warrant more aggressive therapy. (orig.)

  6. Two cases of intracerebral calcification in childhood acute leukemia

    International Nuclear Information System (INIS)

    Two children with acute lynphocytic leukemia (ALL) had intracerebral calcifications. The first case was a girl diagnosed as ALL in her seventh month. She developed two episodes of meningeal leukemia. She was treated by intrathecal methotrexate (MTX) and 19.80 Gy of whole-brain irradiation. Three months after irradiation, CT revealed low-density areas around both the lateral ventricles, especially at the anterior horns, suggesting necrotizing leukoencephalopathy. Seven months after irradiation, CT revealed bilateral gyriform calcifications of both cerebral hemispheres. The second case was a boy diagnosed as ALL at 1.5 years old. He was treated by prop hylactic intrathecal MTX and 24.00 Gy of whole-brain irradiation. Fourteen months after irradiation, CT revealed multiple small punctated calcifications of both cerebral hemispheres. The combination of whole-brain irradiation with MTX therapy was perhaps the cause of the high incidence of these calcifications, because the irradiation doses in these cases were too small to cause these injuries.

In childhood B-cell precursor acute lymphoblastic leukaemia (BCP-ALL, the incidences of individual chromosomal abnormalities are well established and cytogenetics provides a reliable tool for risk stratification for treatment. In spite of this role, a number of patients will relapse. Increasing numbers of additional genetic changes, including deletions and mutations, are being discovered. Their associations with established cytogenetic subgroups and with each other remain unclear. Whether they have a link to outcome is the most important factor in terms of refinement of risk factors in relation to clinical trials. For a number of newly identified abnormalities, appropriately modified therapy has significantly improved outcome. Alternatively, some of these aberrations are providing novel molecular markers for targeted therapy.

    This study aimed at determining the prevalence of INK4 deletions and their impact on outcome in 125 children with acute lymphoblastic leukemia (ALL) at first relapse using real-time quantitative polymerase chain reaction. Patients were enrolled into relapse trials ALL-REZ BFM (ALL-Relapse Berlin-Frankfurt-Münster) 90 and 96. The prevalence of p16(INK4a) and p15(INK4b) homozygous deletions was 35% (44 of 125) and 30% (38 of 125), respectively. A highly significant association of both gene deletions was found with the 2 major adverse prognostic factors known for relapsed childhood ALL: T-cell immunophenotype and first remission duration. There was no correlation between INK4 deletions and probability of event-free survival. These findings argue against an independent prognostic role of INK4 deletions in relapsed childhood ALL.

    ♦ Background: The choices for renal replacement therapy (RRT) in childhood acute kidney injury (AKI) are limited in low-resource settings. Peritoneal dialysis (PD) appears to be the most practical modality for RRT in young children with AKI in such settings. Data from sub-Saharan Africa on the use of PD in childhood AKI are few. ♦ Methods: We performed a retrospective study of children who underwent PD for AKI at a tertiary-care hospital in southwest Nigeria from February 2004 to March 2011 (85 months). ♦ Results: The study included 27 children (55.6% female). Mean age was 3.1 ± 2.6 years, with the youngest being 7 days, and the oldest, 9 years. The causes of AKI were intravascular hemolysis (n = 11), septicemia (n = 8), acute glomerulonephritis (n = 3), gastroenteritis (n = 3), and hemolytic uremic syndrome (n = 2). Peritoneal dialysis was performed manually using percutaneous or adapted catheters. Duration of PD ranged from 6 hours to 12 days (mean: 5.0 ± 3.3 days). The main complications were peritonitis (n = 10), pericatheter leakage (n = 9), and catheter outflow obstruction (n = 5). Of the 27 patients, 19 (70%) survived till discharge. ♦ Conclusions: In low-resource settings, PD can be successfully performed for the management of childhood AKI. In our hospital, the use of adapted catheters may have contributed to the high complication rates. Peritoneal dialysis should be promoted for the management of childhood AKI in low-resource settings, and access to percutaneous or Tenckhoff catheters, dialysis fluid, and automated PD should be increased.

    During the past three decades, improvements in the treatment of childhood leukemia have resulted in high cure rates, particularly for acute lymphoblastic leukemia (ALL). Unfortunately, successful therapy has come with a price, as significant morbidity can result from neurological affects which harm the brain and spinal cord. The expectation and hope is that chemotherapy, as a primary means of CNS therapy, will result in acceptable disease control with less CNS morbidity than has been observed with combinations of chemotherapy and radiotherapy over the past several decades. In this review we discuss the poignant, historical aspects of CNS leukemia therapy, outline current methods of systemic and CNS leukemia therapy, and present imaging findings we have encountered in childhood leukemia patients with a variety of acute neurological conditions. A major objective of our research is to understand the neuroimaging correlates of acute and chronic effects of cancer and therapy. Specific features related to CNS leukemia and associated short-term toxicities, both disease- and therapy-related, are emphasized in this review with the specific neuroimaging findings. Specific CNS findings are similarly important when treating acute myelogenous leukemia (AML), and details of leukemic involvement and toxicities are also presented in this entity. Despite contemporary treatment approaches which favor the use of chemotherapy (including intrathecal therapy) over radiotherapy in the treatment of CNS leukemia, children still occasionally experience morbid neurotoxicity. Standard neuroimaging is sufficient to identify a variety of neurotoxic sequelae in children, and often suggest specific etiologies. Specific neuroimaging findings frequently indicate a need to alter antileukemia therapy. It is important to appreciate that intrathecal and high doses of systemic chemotherapy are not innocuous and are associated with acute, specific, recognizable, and often serious neurological

  13. The role of radiation therapy in childhood acute leukemia. A review from the viewpoint of basic and clinical radiation oncology

    International Nuclear Information System (INIS)

    Radiation therapy has been playing important roles in the treatment of childhood acute leukemia since the 1970s. The first is the preventive cranial irradiation for central nervous system therapy in acute lymphoblastic leukemia. The second is the total body irradiation as conditioning before bone marrow transplantation for children with acute myeloid leukemia in first remission and with acute lymphoblastic leukemia in second remission. Although some late effects have been reported, a part of them could be overcome by technical improvement in radiation and salvage therapy. Radiation therapy for children might have a successful outcome on a delicate balance between efficiencies and potential late toxicities. The role of radiation therapy for childhood acute leukemia was reviewed from the standpoint of basic and clinical radiation oncology in this paper. (author)

  14. Acute necrotizing encephalopathy of childhood: a fatal complication of swine flu

    International Nuclear Information System (INIS)

    Acute necrotizing encephalopathy of childhood (ANEC) is a rare condition characterized by the presence of multifocal symmetrical brain lesions involving mainly thalami, brainstem, cerebellum and white matter. ANEC is a serious and life threatening complication of simple viral infections. We present a case of a young child who developed this condition with classical clinical and radiological findings consistent with ANEC, secondary to swine flu (H1N1). He needed ventilatory support and had profound motor and intellectual deficit on discharge. We report this case with aim of raising awareness about this fatal complication of swine flu which has become a global health care issue these days. (author)

  15. Ophthalmic evaluation of long-term survivors of childhood acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    Thirty-four long-term survivors of childhood acute lymphoblastic leukemia (ALL) underwent comprehensive ophthalmic examinations to detect retinopathy or other ocular sequelae. Sixteen of the 34 patients received whole brain radiation (greater than or equal to 2400 rad). All 18 patients in the non-radiated group had normal eye examinations, while 4 of 16 in the radiated group had ocular abnormalities. None of the ocular abnormalities could be definitely attributed to radiation and all patients had normal visual acuity. No radiation retinopathy was found in either group

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

  17. Comparison of MRI and renal cortical scintigraphy findings in childhood acute pyelonephritis: preliminary experience

    International Nuclear Information System (INIS)

    Objective: The diagnosis of acute pyelonephritis in children remains a clinical challenge. It may cause permanent renal scar formation and results in the chronic renal failure if prompt diagnosis and treatment are delayed. The purpose of this study is to compare magnetic resonance imaging (MRI) and renal cortical scintigraphy (RCS) findings in childhood acute pyelonephritis and to determine pyelonephritic foci in the acute phase. Materials and method: Twenty children (15 females and five males) with symptoms dysuria, enuresis, costovertebral pain, fever of 37.5 degree sign C or more and/or positive urine culture were imaged by unenhanced turbo spin echo T2, spin echo T1-weighted, pre- and post-gadolinium inversion recovery MRI and RCS. Both imaging techniques were read independently by two radiologists and nuclear medicine specialists. Sensitivity and specificity of MRI in detecting acute pyelonephritic foci and scar lesions were calculated. Furthermore, in order to calculate the reliability of MRI over RCS in differentiating scar tissue and acute pyelonephritic foci, follow-up MRI studies were done in six patients after treatment of acute pyelonephritis. Results: Sensitivity and specificity of MRI in the detection of pyelonephritic lesions were found to be 90.9 and 88.8%, respectively. There is no statistically significant difference in lesion detection between the two diagnostic modalities (P>0.05). Conclusion: Post-gadolinium MR images show significant correlation with RCS in the determination of renal pathology. Moreover, the ability of discriminating acute pyelonephritic foci and renal scar in early stages of disease is the superiority of MRI

    Full Text Available Abstract Background Mutations in the nucleophosmin (NPM1 gene have been solely associated with childhood acute myeloid leukemia (AML. We evaluated the frequency of NPM1 mutations in childhood AML, their relation to clinical and cytogenetic features and the presence of common FLT3 and RAS mutations. Results NPM1 mutations were found in 8% of cases. They involved the typical type 'A' mutation and one novel mutation characterized by two individual base pair substitutions, which resulted in 2 amino acid changes (W290 and (S293 in the NPM protein. FLT3/ITD mutations were observed in 12% of the cases and in one NPM1-mutated case bearing also t(8;21 (q22;q22. No common RAS mutations were identified. Conclusions A relatively consistent NPM1 mutation rate was observed, but with variations in types of mutations. The role of different types of NPM1 mutations, either individually or in the presence of other common gene mutations may be essential for childhood AML prognosis.

  20. Late effects of treatment in survivors of childhood acute lymphoblastic leukaemia

    International Nuclear Information System (INIS)

    The overall aim of this study was a comprehensive assessment of the nature and severity of the late effects of treatment in a group of children surviving acute lymphoblastic leukaemia. In the absence of damage preceding treatment, late effects could be ascribed to treatment. Cranial irradiation, methotrexate, L-asparaginase and cytosine arabinoside are therapeutic modalities most likely to cause injury to the central nervous system. Survivors of childhood leukaemia also showed an increase in weight-for-height during and after therapy which appeared to be the consequence of a loss in statural growth as well as increasing weight-for-age. Assessment of endocrine function in leukaemia survivors indicated abnormalities in the regulation of growth hormone and thyroid stimulating hormone in some patients. Survivors of childhood leukaemia were shown to have an intellectual deficit compared with their siblings and a high incidence of visual-perceptual defects. The intellectual effects of lower doses of cranial irradiation are as yet unknown. A variety of minor neurological abnormalities were detected among leukaemia survivors and thought to be related to preceding central nervous system 'prophylactic' chemotherapy and irradiation. A new instrument, the functional deficit score, was derived to reflect overall outcome in survivors of childhood leukaemia. With few exceptions, leukaemia survivors in this study had received 2400 rads of deep x-ray therapy as cranial irradiation. This dosage has since been reduced world-wide. Current cranial irradiation 'prophylaxis' consists of 1800 rad of megavoltage radiotherapy

    The association between tobacco smoke and acute myeloid leukemia (AML) is well established in adults but not in children. Individual-level data on parental cigarette smoking were obtained from 12 case-control studies from the Childhood Leukemia International Consortium (CLIC, 1974-2012), including 1,330 AML cases diagnosed at age controls. We conducted pooled analyses of CLIC studies, as well as meta-analyses of CLIC and non-CLIC studies. Overall, maternal smoking before, during, or after pregnancy was not associated with childhood AML; there was a suggestion, however, that smoking during pregnancy was associated with an increased risk in Hispanics (odds ratio = 2.08, 95% confidence interval (CI): 1.20, 3.61) but not in other ethnic groups. By contrast, the odds ratios for paternal lifetime smoking were 1.34 (95% CI: 1.11, 1.62) and 1.18 (95% CI: 0.92, 1.51) in pooled and meta-analyses, respectively. Overall, increased risks from 1.2- to 1.3-fold were observed for pre- and postnatal smoking (P < 0.05), with higher risks reported for heavy smokers. Associations with paternal smoking varied by histological type. Our analyses suggest an association between paternal smoking and childhood AML. The association with maternal smoking appears limited to Hispanic children, raising questions about ethnic differences in tobacco-related exposures and biological mechanisms, as well as study-specific biases.

  2. Deregulated WNT signaling in childhood T-cell acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    WNT signaling has been implicated in the regulation of hematopoietic stem cells and plays an important role during T-cell development in thymus. Here we investigated WNT pathway activation in childhood T-cell acute lymphoblastic leukemia (T-ALL) patients. To evaluate the potential role of WNT signaling in T-cell leukomogenesis, we performed expression analysis of key components of WNT pathway. More than 85% of the childhood T-ALL patients showed upregulated β-catenin expression at the protein level compared with normal human thymocytes. The impact of this upregulation was reflected in high expression of known target genes (AXIN2, c-MYC, TCF1 and LEF). Especially AXIN2, the universal target gene of WNT pathway, was upregulated at both mRNA and protein levels in ∼40% of the patients. When β-CATENIN gene was silenced by small interfering RNA, the cancer cells showed higher rates of apoptosis. These results demonstrate that abnormal WNT signaling activation occurs in a significant fraction of human T-ALL cases independent of known T-ALL risk factors. We conclude that deregulated WNT signaling is a novel oncogenic event in childhood T-ALL

    Sjögren syndrome is an autoimmune disease characterized by dry mouth and eyes, known as sicca symptoms. The exact spectrum of neurological involvement, especially of the central nervous system, in childhood Sjögren syndrome has not been well defined. We report a girl who presented with acute febrile brainstem encephalitis. In retrospect, she had exhibited a preceding history of recurrent conjunctivitis and strong halitosis that could be considered as sicca symptoms. The histopathology results of a minor salivary biopsy, the presence of anti-SSA/Ro antibody, and keratoconjunctivitis confirmed the diagnosis of Sjögren syndrome. Commonly observed features in previously reported patients with childhood Sjögren syndrome and central nervous system complications have included fever at the time of neurologic presentation, cerebrospinal fluid pleocytosis, abnormal neuroimaging, and positivity for several specific antibodies. In children presenting with unknown acute febrile encephalopathy, Sjögren syndrome should be included in the differential diagnosis, especially when sicca symptoms are present. PMID:26006751

  4. TLR Stimulation of Bone Marrow Lymphoid Precursors from Childhood Acute Leukemia Modifies Their Differentiation Potentials

    Directory of Open Access Journals (Sweden)

    Elisa Dorantes-Acosta

    2013-01-01

    Full Text Available Acute leukemias are the most frequent childhood malignancies worldwide and remain a leading cause of morbidity and mortality of relapsed patients. While remarkable progress has been made in characterizing genetic aberrations that may control these hematological disorders, it has also become clear that abnormalities in the bone marrow microenvironment might hit precursor cells and contribute to disease. However, responses of leukemic precursor cells to inflammatory conditions or microbial components upon infection are yet unexplored. Our previous work and increasing evidence indicate that Toll-like receptors (TLRs in the earliest stages of lymphoid development in mice and humans provide an important mechanism for producing cells of the innate immune system. Using highly controlled co-culture systems, we now show that lymphoid precursors from leukemic bone marrow express TLRs and respond to their ligation by changing cell differentiation patterns. While no apparent contribution of TLR signals to tumor progression was recorded for any of the investigated diseases, the replenishment of innate cells was consistently promoted upon in vitro TLR exposure, suggesting that early recognition of pathogen-associated molecules might be implicated in the regulation of hematopoietic cell fate decisions in childhood acute leukemia.

  5. Cranial radiotherapy predisposes to abdominal adiposity in survivors of childhood acute lymphocytic leukemia

    International Nuclear Information System (INIS)

    Advances in treatment of acute lymphocytic leukemia increased the likelihood of developing late treatment-associated effects, such as abdominal adiposity, increasing the risk of cardiovascular disease in this population. Cranial radiotherapy is one of the factors that might be involved in this process. The aim of this study was to determine the effect of cranial radiotherapy on adiposity indexes in survivors of acute lymphocytic leukemia. A comparative cross-sectional study of 56 acute lymphocytic leukemia survivors, chronological age between 15 and 24 years, assigned into two groups according to the exposure to cranial radiotherapy (25 irradiated and 31 non-irradiated), assessed according to body fat (dual energy X-ray absorptiometry), computed tomography scan-derived abdominal adipose tissue, lipid profile, and insulin resistance. Cranial radiotherapy increased body fat and abdominal adipose tissue and altered lipid panel. Yet, lipids showed no clinical relevance so far. There were significantly more obese patients among those who received cranial radiotherapy (52% irradiated versus 22.6% non-irradiated), based on dual energy X-ray absorptiometry body fat measurements. Nonetheless, no association was observed between cranial radiotherapy and body mass index, waist circumference, waist-to-height ratio or insulin resistance. Adolescent and young adult survivors of childhood acute lymphocytic leukemia showed an increase in body fat and an alteration of fat distribution, which were related to cranial radiotherapy. Fat compartment modifications possibly indicate a disease of adipose tissue, and cranial radiotherapy imports in this process

The digital electroencephalogram was recorded with electrodes according to 10-20 international system, and a supplementary electrode, between C3 and T3 or C4 and T4 - C5 or C6, respectively, at the side with a higher number of spikes. The averaging of the spikes was carried. Localization and the laterality of the spikes were analyzed. Seizures involving a superior limb occurred in a higher proportion of cases with spikes of maximum negativity in C3, C4. Independent epileptiform activity, different from centrotemporal, was more frequent in the cases were the maximum negativity of the spikes occurred in C3 or C4 regions. There are clinical and electroencephalographic differences according to the localization of the discharges

  13. TESTIN Induces Rapid Death and Suppresses Proliferation in Childhood B Acute Lymphoblastic Leukaemia Cells.

    Full Text Available Childhood acute lymphoblastic leukaemia (ALL is the most common malignancy in children. Despite high cure rates, side effects and late consequences of the intensive treatments are common. Unquestionably, the identification of new therapeutic targets will lead to safer, more effective treatments. We identified TES promoter methylation and transcriptional silencing as a very common molecular abnormality in childhood ALL, irrespective of molecular subtype. The aims of the present study were to demonstrate that TES promoter methylation is aberrant, to determine the effects of TES re-expression in ALL, and to determine if those effects are mediated via TP53 activity.Normal fetal and adult tissue DNA was isolated and TES promoter methylation determined by Sequenom MassARRAY. Quantitative RT-PCR and immunoblot were used to confirm re-expression of TES in ALL cell lines after 5'-aza-2'-deoxycytidine (decitabine exposure or transfection with TES expression plasmids. The effects of TES re-expression on ALL cells were investigated using standard cell proliferation, cell death and cell cycle assays.In this study, we confirm that the TES promoter is unmethylated in normal adult and fetal tissues. We report that decitabine treatment of ALL cell lines results in demethylation of the TES promoter and attendant expression of TES mRNA. Re-expression of TESTIN protein in ALL cells using expression plasmid transfection results in rapid cell death or cell cycle arrest independent of TP53 activity.These results suggest that TES is aberrantly methylated in ALL and that re-expression of TESTIN has anti-leukaemia effects which point to novel therapeutic opportunities for childhood ALL.

    Prognostic impact of peripheral blood white blood cell count (WBC) at the diagnosis of childhood acute lymphoblastic leukaemia (ALL) was evaluated in a population-based consecutive series of 2666 children aged 1-15 treated for ALL between 1992 and 2008 in the five Nordic countries (Denmark, Finland......, Iceland, Norway and Sweden). Ten-year event-free (pEFS(10 y)) survival and overall (pOS(10 y)) survival were 0.75 ± 0.01 and 0.85 ± 0.01, respectively. Although treatment intensity was determined by WBC, non-remission and relapsed patients still had significantly higher WBC than those in remission for B-cell...

  15. Comparison of three methods of central-nervous-system prophylaxis in childhood acute lymphoblastic leukaemia

    International Nuclear Information System (INIS)

    A retrospective comparison was made of three methods of central-nervous-system prophylaxis in childhood acute lymphoblastic leukaemia; (1) intrathecal methotrexate only; (2) intermediate-dose methotrexate infusion and intrathecal methotrexate and; (3) 2400 rads cranial irradiation and intrathecal methotrexate. The incidence of primary meningeal relapse was statistically significantly lower in both standard-risk patients (age > 24 months and 120 months and/or white-cell count > 20 000) whose central-nervous-system prophylaxis included cranial irradiation. The disease-free and overall survival of irradiated increased-risk patients was significantly better than that of unirradiated increased-risk patients. The disease-free survival of standard-risk patients who received intermediate-dose methotrexate was statistically superior to that of the remaining standard-risk patients. There were no significant differences in overall survival between the three groups of standard-risk patients. (author)

    Full Text Available Abstract Background Most studies on Health-related Quality of Life (HRQOL in children with cancer were conducted in developed countries. The aims of this study were to assess the HRQOL in childhood acute lymphoblastic leukemia (ALL patients in Indonesia and to assess the influence of demographic and medical characteristics on HRQOL. Methods After cultural linguistic validation, a cross-sectional study of HRQOL was conducted with childhood ALL patients and their guardians in various phases of treatment using the Pediatric Quality of Life Inventory™ (PedsQL™ 4.0 Generic Core Scale and the Pediatric Quality of Life Inventory™ (PedsQL™ 3.0 Cancer Module. Results Ninety-eight guardians and 55 patients participated. The internal consistency of both scales ranged from 0.57 to 0.92. HRQOL of Indonesian patients was comparable with those in developed countries. There were moderate to good correlations between self-reports and proxy-reports, however guardians tended to report worse HRQOL than patients. Children of the 2–5 year-group significantly had more problems in procedural anxiety, treatment anxiety and communication subscales than in older groups (p Conclusion Younger children had more problems in procedural anxiety, treatment anxiety and communication subscales. Therefore, special care during intervention procedures is needed to promote their normal development. Psychosocial support should be provided to children and their parents to facilitate their coping with disease and its treatment.

    WHO/UNICEF currently recommend that childhood malaria and pneumonia be managed together in the community; most African countries are in the process of developing this policy. We conducted a cross-sectional study to determine maternal awareness of general danger signs of childhood illnesses and the prevalence, determinants and sources of pre-hospital treatment by mothers during their child's acute respiratory illness in a poor urban community in south-western Nigeria. A total of 226 mothers were interviewed. Only 4.9% of the mothers were aware of the two pneumonia symptoms: difficult breathing and fast breathing. About 75% of the children were given pre-hospital medication at home and only 16.5% of them received the drugs within 24 hour of symptom recognition. Drug shops/patent medicine vendors (PMVs; 70.6%) were the most common source of care. Wishing to try home management first (46.6%); waiting for the child to improve (14.4%) and lack of money (31.6%) delayed care-seeking. Older maternal age (aOR 2.3; 95% CI 1.2-4.4) and having a child with cough and difficult and/or fast breathing (aOR 2.3; 95% CI 1.1-5.2) were positive predictors of pre-hospital treatment. Maternal education and adequately equipping PMVs could improve prompt access to integrated community-based child health services in Nigeria. PMID:24029675

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

    Acute lymphoblastic leukemia (ALL) is a malignant disease characterized by an uncontrolled proliferation of immature lymphoid cells. ALL is the most common hematologic malignancy in early childhood, and it reaches peak incidence between the ages of 2 and 3 years. The prognosis of ALL is associated with aberrant gene expression, in addition to the presence of numerical or structural chromosomal alterations, age, race, and immunophenotype. The Relapse rate with regard to pharmacological treatment rises in childhood; thus, the expression of biomarkers associated with the activation of cell signaling pathways is crucial to establish the disease prognosis. Intracellular pathways involved in ALL are diverse, including Janus kinase/Signal transducers and transcription activators (JAK-STAT), Phosphoinositide-3-kinase-protein kinase B (PI3K-AKT), Ras mitogen-activated protein kinase (Ras-MAPK), Glycogen synthase kinase-3β (GSK-3β), Nuclear factor-kappa beta (NF-κB), and Hypoxia-inducible transcription factor 1α (HIF-1α), among others. In this review, we present several therapeutic targets, intracellular pathways, and molecular markers that are being studied extensively at present. PMID:27065575

    Along with the growing epidemic of overweight the risk of atherosclerosis, cardiovascular disease morbidity and mortality are increasing markedly. Metabolic syndrome (MS) is a condition clustering together several risk factors of those complications such as visceral obesity, glucose intolerance, arterial hypertension and dislipidemia. The risk of obesity in acute lymphoblastic leukemia (ALL) survivors is higher than in general population. We aimed to assess (1) the relationships between chosen adipokines and neuropeptides, chemotherapy, CRT, and body fatness and (2) evaluate adipokines and neuropeptides concentrations as a new markers of MS in children. We conducted cross-sectional evaluation of 82 ALL survivors (median age: 13.2 years; range: 4,8-26,2; median time from treatment: 3.2 years), including fasting laboratory testing: peptides (leptin, GLP-1, orexin, PYY, apelin), total cholesterol and its fractions, triglycerides; anthropometric measurements (weight, height), systolic and diastolic blood pressure. We estimated percentiles of body mass index and percentiles of blood pressure. Between 82 survivors overweight and diastolic hypertension was diagnosed in 31% of patients (35% in CRT group) and 15% respectively. At least one abnormality in lipids concentrations was found in 43%. Girls were more affected than boys. Statistically significant increased in leptin and apelin concentrations and decreased in soluble leptin receptor concentrations in the overweight group were observed compared to the non overweight subjects. Significant increase in orexin levels in females who had received CRT compared to those who had not received CRT was found. CRT is the main risk factor of elevated of body mass among survivors of childhood leukemia. Dyslipidemia and hypertension, along with increased adiposity indicate higher risk of MS development. Girls are more affected than boys. Leptin, orexin and apelin seem to be good markers of increased adiposity especially after CRT

    Thyroid complications are known side effects of irradiation. However, the risk of such complications in childhood acute leukemia survivors who received either central nervous system irradiation or hematopoietic stem cell transplantation is less described. We prospectively evaluated the incidence and risk factors for thyroid dysfunction and tumors in survivors of childhood acute myeloid or lymphoid leukemia. A total of 588 patients were evaluated for thyroid function, and 502 individuals were assessed for thyroid tumors (median follow-up duration: 12.6 and 12.5 years, respectively). The cumulative incidence of hypothyroidism was 17.3% (95% CI: 14.1–21.1) and 24.6% (95% CI: 20.4–29.6) at 10 and 20 years from leukemia diagnosis, respectively. Patients who received total body irradiation (with or without prior central nervous system irradiation) were at higher risk of hypothyroidism (adjusted HR: 2.87; P=0.04 and 2.79, P=0.01, respectively) as compared with transplanted patients who never received any irradiation. Patients transplanted without total body irradiation who received central nervous system irradiation were also at higher risk (adjusted HR: 3.39; P=0.02). Patients irradiated or transplanted at older than 10 years of age had a lower risk (adjusted HR: 0.61; P=0.02). Thyroid malignancy was found in 26 patients (5.2%). Among them, two patients had never received any type of irradiation: alkylating agents could also promote thyroid cancer. The cumulative incidence of thyroid malignancy was 9.6% (95% CI: 6.0–15.0) at 20 years. Women were at higher risk than men (adjusted HR: 4.74; P=0.002). In conclusion, thyroid complications are frequent among patients who undergo transplantation after total body irradiation and those who received prior central nervous system irradiation. Close monitoring is thus warranted for these patients. Clinicaltrials.gov identifier: NCT 01756599. PMID:26969082

    Full Text Available Benign prostatic hyperplasia (BPH is a disease that affects over 50% of males aged 50 years or older. In men aged >80 years, the incidence is 90%. BPH occurs in 9-25% of males aged 40 to 79 years. Fifty percent of patients with BPH are symptomatic. The symptoms include reduced urinary flow, nocturia, defective bladder emptying, urinary hesitancy, and dysuria. Disease progression can be associated with acute urinary retention (AUR. Prostatic obstruction includes mechanical and dynamic components, the latter mediated by alpha-muscarinic receptors. Treatment with alpha-1-blockers (alfuzosin, doxazosin, tamsulosin, and terazosin leads to rapid amelioration of symptoms and urinary flow, usually within one or two weeks. The 5-alpha reductase inhibitors (5-ARIs are “disease-modifying drugs.” They control the growth of the prostate by blocking the conversion of testosterone into dihydrotestosterone (DHT. Finasteride is a 5–ARI that is selective for type 2 receptors. Dutasteride is a powerful inhibitor of both 5- alpha reductase isoforms (type 1 and 2 and produces more complete suppression of DHT synthesis than finasteride. Dutasteride also has a much longer half-life than finasteride (five weeks versus five to six hours. The authors review the results of clinical trials involving finasteride and dutasteride, with and without alpha-1-blockers, highlighting the important role of dutasteride in improving acute urinary retention and eliminating the need for surgical therapy.

    A deficit of normal immune stimulation in early childhood is a suspected risk factor for both childhood acute lymphoblastic leukemia (ALL) and allergies. The present study utilized a population-based case-control design using medical claims data from the National Health Insurance Research Database of Taiwan to evaluate the association between allergy and childhood leukemia. Eight hundred forty-six childhood ALL patients who were newly diagnosed during 2000 to 2008 and were older than 1 but less than 10 years of age were individually matched with 3,374 controls based on sex, birth date, and time of diagnosis (reference date for the controls). Conditional logistic regression was performed to assess the association between childhood ALL and allergies. An increased risk of ALL was observed with having an allergy less than 1 year before the case's ALL diagnosis (odds ratio (OR) = 1.7, 95% confidence interval (CI): 1.5, 2.0), more than 1 year before the case's diagnosis (OR = 1.3, 95% CI: 1.1, 1.5), and before the age of 1 year (OR = 1.4, 95% CI: 1.1, 1.7). These results suggest that the pathogenesis of childhood ALL and allergy share a common biologic mechanism. PMID:23171876

    Immune thrombocytopenia (ITP) is an acute self-limited disease of childhood, mostly resolving within 6 months irrespective of whether therapy is given or not. Treatment options when indicated include corticosteroids, intravenous immune globulin (IVIG), and anti-RhD immunoglobulin. We reviewed our 32 years' experience for first-line therapy of acute ITP. Five hundred forty-one children (mean age: 5.3 years) diagnosed and treated for ITP were evaluated retrospectively. Among 491 acute ITP patients, IVIG was used in 27%, high-dose steroids in 27%, low-dose steroids in 20%, anti-D immunoglobulin G (IgG) in 2%, and no therapy in 22%. When the initial response (platelets >50 × 10(9)/L) to first-line treatment modalities were compared, 89%, 84%, and 78% patients treated by low-dose steroids, high-dose steroids, and IVIG responded to treatment, respectively (P > .05). Mean time to recovery of platelets was 16.8, 3.8, and 3.0 days in patients treated with low-dose steroids, high-dose steroids, and IVIG, respectively (P < .0001). Thrombocytopenia recurred in 23% of low-dose steroid, 39% of high-dose steroid, and in 36% of IVIG (P < .0001) treatment groups. Of 108 patients who were observed alone, 4 (3%) had a recurrence on follow-up and only 2 of these required treatment subsequently. Recurrence was significantly less in no therapy group compared with children treated with 1 of the 3 options of pharmacotherapy (P < .0001). Response rates were similar between patients treated by IVIG and low- and high-dose steroids; however, time to response was slower in patients treated with low-dose steroids compared with IVIG and high-dose steroids.

    Mutations of receptor tyrosine kinases are implicated in the constitutive activation and development of human hematologic malignancies. Mutations in fms-like tyrosine kinase 3 (FLT3) gene including internal tandem duplication (ITD) and point mutation in the tyrosine kinase domain (TKD) as well as in nucleoplasmin (NPM1) gene are associated with pathogenesis of acute myeloblastic leukemia (AML). Several reports have demonstrated high incidences of the FLT3 and NPM1 mutations in adult AML patients. Since the pathogenesis of pediatric AML is different from that of adult and the FLT3 and NPM1 mutations have not been well characterized in childhood AML. Therefore, the objective of this study was to determine the frequencies of FLT3 and NPM1 mutations in 64 newly diagnosed childhood AML patients. All blood and bone marrow samples were previously diagnosed with AML by using flow cytometry and/or cytochemistry. FLT3-ITD and FLT3-TKD were detected by PCR and PCR-RFLP methods, respectively. The NPM1 mutation was analyzed by PCR and direct DNA sequencing. The FLT3 mutations were detected in 7 of 64 (11.1%), including FLT3-ITD in 4 of 64 (6.3%) and FLT-TKD in 3 of 62 (4.8%). The NPM1 mutation was not detected in this cohort. By multivariate analysis, white blood cell counts, peripheral blood and bone marrow blast cell counts at diagnosis were significantly higher in children with FLT3-ITD (P<0.05). In addition, the median percentage of CD117 was significantly higher in leukemic blast cells with FLT3-ITD than those with wild type (P=0.01). We did not find any FLT3 mutations in children aged less than 5 years. The AML M3 cell type was most frequently associated with FLT3 gene mutations (50%). In conclusion, the FLT3 mutations was found in 11.1% but none of NPM1 mutation was detected in Thai children with AML. These data support the hypothesis of different biology and pathogenesis between adult and childhood AML. PMID:22126574

    The long-term impact of cesarean delivery (CD) on the health of the offspring is being explored methodically. We sought to investigate the effect of birth by (a) prelabor and (b) during-labor CD on the risk of early-onset (≤3 years) acute lymphoblastic leukemia (ALL), specifically of its prevailing precursor B (B-ALL) subtype. A total of 1099 incident cases of ALL (957 B-ALL), 131 of acute myeloid leukemia (AML), and their 1 : 1 age-matched and sex-matched controls, derived from the Nationwide Registry for Childhood Hematological Malignancies (1996-2013), were analyzed using multivariate regression models. A null association was found between prelabor and/or during labor CD and either ALL (B-ALL) or AML in the 0-14 age range. By contrast, birth by CD increased significantly the risk of early-onset ALL [odds ratioCD (ORCD)=1.57, 95% confidence interval (CI): 1.10-2.24] mainly on account of prelabor CD (ORprelaborCD=1.66, 95% CI: 1.13-2.43). The respective figures were even higher for the early-onset precursor B-ALL (ORCD=1.66, 95% CI: 1.15-2.40 and ORprelaborCD=1.79, 95% CI: 1.21-2.66), whereas no association emerged for early-onset AML. Prelabor CD, which deprives exposure of the fetus/infant to the presumably beneficial effect of stress hormones released in both vaginal labor and during labor CD, was associated exclusively with an increased risk of early-onset ALL, particularly the precursor B-ALL subtype. If confirmed, these adverse long-term outcomes of CD may point to re-evaluation of prelabor CD practices and prompt scientific discussion on the best ways to simulate the effects of vaginal delivery, such as a precesarean induction of labor.

  14. Factors associated with IQ scores in long-term survivors of childhood acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    To identify factors which might be associated with intellectual function following treatment for childhood acute lymphoblastic leukemia, 50 long-term survivors were studied using the Wechsler Intelligence Scale for Children-Revised. All patients were diagnosed between 1972 and 1974 and were treated on a single clinical trial protocol with identical induction and maintenance chemotherapy plus central nervous system prophylaxis that included cranial radiation. The mean full scale IQ score for the group was 95 (SEM 2.0), with mean verbal IQ of 94.4 and mean performance IQ of 96.9. Factors which were found to be closely associated with a lower IQ score included female sex (in both verbal IQ and full-scale IQ), longer duration of chemotherapy (in performance IQ), and younger age at the time of radiation (in both verbal IQ and full-scale IQ). The age at the time of radiation was found to be significantly correlated with discrepancy between verbal and performance IQ, with younger age being associated with verbal IQ scores higher than performance IQ scores. When analyses were performed within specific subgroups of patients defined by sex and age at the time of radiation, dose of cranial radiation, concomitant intrathecal methotrexate therapy, and duration of therapy were all found to be correlated with a lower level of intellectual function. These preliminary findings provide direction for future studies to help identify high-risk patients

  15. Childhood acute disseminated encephalomyelitis: the role of brain and spinal cord MRI

    International Nuclear Information System (INIS)

    Background. It is recognised that the clinical and radiological spectrum of childhood acute disseminated encephalomyelitis (ADEM) is wide. Objective. To determine whether initial MRI features are predictive of clinical outcome and to determine the role of MRI in the management of ADEM. Materials and methods. The MRI scans of ten consecutive children (eight boys, two girls), clinically and radiologically diagnosed to have ADEM, were retrospectively reviewed. Follow-up MRI was available for eight patients. Results. Lesions ranged from small and punctate (<1 cm) to moderate sized and confluent (4-5 cm) to diffuse and extensive. Spinal cord lesions, seen in five of seven children, were contiguous or segmental. Seven children (70%) made good clinical recovery while three children (30%) remained severely handicapped. There was no correlation between the site, extent and pattern of involvement and clinical outcome. However, the evolution of MRI findings on follow-up correlated well with the subsequent clinical course and outcome. Conclusions. Although the extent and site of lesions on initial MRI scans are not predictive of clinical outcome, early MRI of the brain and spine is useful in aiding clinical diagnosis, and subsequent follow-up MRI is helpful in monitoring disease progression.

  17. Neuropsychological sequelae of central nervous system prophylaxis in survivors of childhood acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    We assessed neuropsychologically 106 children with acute lymphoblastic leukemia (ALL) who had all received cranial irradiation for the prevention of central nervous system (CNS) leukemia 1-13 years previously. Children were assessed for adverse late effects of their therapy, using age-appropriate Wechsler measures of overall intellectual ability and supplementary tests. Forty-five siblings near in age to the patients were tested as controls. The patients who had had the most intensive central nervous system (CNS) prophylaxis were found to have a WISC-R Full Scale IQ 17 points lower than the sibling control group. Performance IQ was more affected than verbal IQ. The patients were more easily distracted and less able to concentrate. The severity of the aftereffects was related to younger age at the time of CNS prophylaxis and to a higher dose of cranial irradiation but not to time since CNS prophylaxis. CNS prophylaxis using a combination of cranial irradiation and intrathecal methotrexate has lowered the incidence of CNS relapse in childhood ALL but is associated with considerable long-term morbidity in survivors

    Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Current treatment strategies for childhood ALL result in long-term remission for approximately 90% of patients. However, the therapeutic response is worse among those who relapse. Several risk stratification approaches based on clinical and biological aspects have been proposed to intensify treatment in patients with high risk of relapse and reduce toxicity on those with a greater probability of cure. The detection of residual leukemic cells (minimal residual disease, MRD) is the most important prognostic factor to identify high-risk patients, allowing redefinition of chemotherapy. In the last decades, several standardized research protocols evaluated MRD using immunophenotyping by flow cytometry and/or real-time quantitative polymerase chain reaction at different time points during treatment. Both methods are highly sensitive (10−3 a 10−5), but expensive, complex, and, because of that, require qualified staff and frequently are restricted to reference centers. The aim of this article was to review technical aspects of immunophenotyping by flow cytometry and real-time quantitative polymerase chain reaction to evaluate MRD in ALL. PMID:27158437

    Poisoning represents one of the most common medical emergencies in childhood, and epidemiological properties differ from country to country. Thus, special epidemiological surveillance for each country is necessary to determine the problem according to which preventive measures can be taken. The purpose of this study was to clarify the characteristics of acute poisoning cases admitted to a pediatric referral hospital. All poisoned patients under 17 years of age, except for cases food poisoning, presenting to the Emergency Department (ED) from January 1995 to December 2000 were determined. The information about each case was recorded on standardized forms and a retrospective chart review survey was done. Complete epidemiological and clinical data were obtained for 489 patients. The mean age of all poisoned patients (mean +/- standard deviation) was 5.96 +/- 4.87 years, and the age range was 0.01 to 17 years. Three hundred and thirty-one children, forming 63.6% of all patients, were under five years of age. Slightly more boys (52.3%) than girls were intoxicated at ages less than 10 years, after which more girls (79%) than boys were involved. The majority of all cases were due to accidental poisoning (78.1% of all poisonings) which occurred mostly in children under five years of age (73.3%). While accidental poisonings (97.1%) were the most common mode of poisoning between 1-5 years, self-poisonings (67.3%) had the highest ratio in cases over 10 years of age. In patients younger than one year of age, 74.2% of all poisonings were due to therapeutical error. Drugs were the most frequent offending agent (57.7%), followed by ingestion of a caustic/corrosive substance (16.8%) and carbon monoxide (CO) intoxication (9.4%). Analgesics were the most common agents, forming 23.7% of all poisonings due to drugs, followed by ingestion of multiple drugs and tricyclic antidepressants at ratios of 21.6% and 9.6%, respectively. The most common route of poisoning was ingestion of the

    Deletion of chromosome 9p21 is a crucial event for the development of several cancers including acute lymphoblastic leukemia (ALL). Double strand breaks (DSBs) triggering 9p21 deletions in ALL have been reported to occur at a few defined sites by illegitimate action of the V(D)J recombination activating protein complex. We have cloned 23 breakpoint junctions for a total of 46 breakpoints in 17 childhood ALL (9 B- and 8 T-lineages) showing different size deletions at one or both homologous chromosomes 9 to investigate which particular sequences make the region susceptible to interstitial deletion. We found that half of 9p21 deletion breakpoints were mediated by ectopic V(D)J recombination mechanisms whereas the remaining half were associated to repeated sequences, including some with potential for non-B DNA structure formation. Other mechanisms, such as microhomology-mediated repair, that are common in other cancers, play only a very minor role in ALL. Nucleotide insertions at breakpoint junctions and microinversions flanking the breakpoints have been detected at 20/23 and 2/23 breakpoint junctions, respectively, both in the presence of recombination signal sequence (RSS)-like sequences and of other unspecific sequences. The majority of breakpoints were unique except for two cases, both T-ALL, showing identical deletions. Four of the 46 breakpoints coincide with those reported in other cases, thus confirming the presence of recurrent deletion hotspots. Among the six cases with heterozygous 9p deletions, we found that the remaining CDKN2A and CDKN2B alleles were hypermethylated at CpG islands. PMID:19484265

    Bendamustine combined with other drugs is clinically efficacious for some adult lymphoid malignancies, but to date there are no reports of the use of such combinatorial approaches in pediatric patients. We investigated the in vitro activity of bendamustine combined with other antimetabolite drugs on B cell precursor acute lymphoblastic leukemia (BCP-ALL) cell lines established from pediatric patients with refractory or relapsed ALL. We also developed a mathematically drown improved isobologram method to assess the data objectively. Three BCP-ALL cell lines; YCUB-2, YCUB-5, and YCUB-6, were simultaneously exposed to various concentrations of bendamustine and cladribine, cytarabine, fludarabine, or clofarabine. Cell growth inhibition was determined using the WST-8 assay. Combinatorial effects were estimated using our improved isobologram method with IC80 (drug concentration corresponding to 80 % of maximum inhibition). Bendamustine alone inhibited ALL cell growth with mean IC80 values of 11.30-18.90 μg/ml. Combinations of bendamustine with other drugs produced the following effects: (1) cladribine; synergistic-to-additive on all cell lines; (2) cytarabine; synergistic-to-additive on YCUB-5 and YCUB-6, and synergistic-to-antagonistic on YCUB-2; (3) fludarabine; additive-to-antagonistic on YCUB-5, and synergistic-to-antagonistic on YCUB-2 and YCUB-6; (4) clofarabine; additive-to-antagonistic on all cell lines. Flow cytometric analysis also showed the combination effects of bendamustine and cladribine. Bendamustine/cladribine or bendamustine/cytarabine may thus represent a promising combination for salvage treatment in childhood ALL. PMID:26886449

  7. Salivirus in Children and Its Association with Childhood Acute Gastroenteritis: A Paired Case-Control Study.

    Full Text Available Salivirus was recently discovered in children with gastroenteritis and in sewage. Though a causative role for salivirus in childhood gastroenteritis was suggested in the previous study, the relationship between salivirus and acute gastroenteritis has not yet been clearly clarified. The sewage strain reported by Ng, although represented by incomplete genome sequencing data, was distinct from previously reported saliviruses, and had not previously been detected in humans. A case-control study examining 461 paired stool samples from children with diarrhea and healthy controls (1:1 was conducted in this study. Also, common diarrheal viruses were detected and complete genome of a salivirus was determined. Results showed that salivirus was detected in 16 (3.5% and 13 (2.8% of the case and control samples, respectively; no differences in detection rates (p=0.571 or mean values of viral loads (p=0.400 were observed between the groups. Multivariate Cox regression revealed no association between salivirus and gastroenteritis (p=0.774. The data also demonstrated that salivirus infection did not exacerbate clinical symptoms of gastroenteritis in children. Furthermore, complete genome sequence of a salivirus recovered from the feces of a child with diarrhea (i.e., SaliV-FHB shared a 99% nucleotide identity with the sewage strain. In conclusion, a paired case-control study did not support a causative role for salivirus strains detected in this study with pediatric gastroenteritis. This study also demonstrated that all known saliviruses can be detected in the feces of children with or without gastroenteritis.

  8. Long-term sequelae after chemotherapy and radiotherapy for childhood acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    Background: Effective forms of treatment for acute lymphoblastic leukemia (ALL) in childhood now result in survival rates of more than 70%. With improving cure rates increasing interest has been focused on adverse late effects caused by chemotherapy and cranial irradiation. Methods: We investigated 40 survivors, 22 males and 18 females with an average age of 15.8 years (6.6 to 28.1), all treated at the Children's Hospital of Innsbruck, Austria, after a follow-up of 9.2 years (4.6 - 20) on average in continuous complete remission. Our evaluation included cardiac status, growth, endocrinological function and a wide variety of other clinical and laboratory investigations. To identify cardiac dysfunction due to anthracyclines we performed Dobutamine-Stress-Echocardiography (DSE) using a graded dosage regimen (1.0, 2.5 and 5.0 μg/kg/min). We compared the DSE data with those obtained from 17 age-matched control subjects. Results: Conventional echocardiography revealed only 4 patients (11.4%) with abnormalities of left ventricular contractility (measured as left ventricular shortening fraction). In contrast DSE detected a 3-fold higher percentage of patients with cardiac dysfunction. There was no correlation between total cumulative anthracycline dose, age at time of diagnosis and length of follow-up with incidence of abnormalities. Primary hypothyroidism in 4 patients (10%) and a permanent linear growth retardation in 5 patients (12%, all of which had been irradiated) were the only endocrinological problems detected. No survivor showed hemato-immunological disturbances. Remarkably, transfusion- associated sequelae, liver or kidney dysfunction were not found. Conclusion: The high incidence of late cardiac effects requires continued monitoring of patients after ALL treatment. In this respect, DSE revealed to be a sensitive method. (author)

    2011-01-01

    Full Text Available Objective: With the survival rate of acute lymphoblastic leukemia (ALL surpassing 90 percent within this decade, new research is emerging in the field of late effects. A review of the research investigating the relationship of treatment regimens for ALL to specific late effect deficits, underlying mechanisms, and possible remediation is warranted to support continued studies.Methods: The clinical literature was briefly surveyed to describe the occurrence and topography of late effects, specifically neurocognitive deficits. Additionally, the preclinical literature was reviewed to uncover potential underlying mechanisms of these deficits. The advantages of using rodent models to answer these questions are outlined, as is an assessment of the limited number of rodent models of childhood cancer treatment.Results: The literature supports that childhood survivors of ALL exhibit academic difficulties and are more likely to be placed in a special education program. Behavioral evidence has highlighted impairments in the areas of attention, working memory, and processing speed, leading to a decrease in full scale IQ. Neurophysiological and preclinical evidence for these deficits has implicated white matter abnormalities and acquired brain damage resulting from specific chemotherapeutic agents commonly used during treatment.Conclusions: The exact role of chemotherapeutic agents in learning deficits remains mostly unknown. Recommendations for an improved rodent model of learning deficits in childhood cancer survivors are proposed, along with suggestions for future directions in this area of research, in hopes that forthcoming treatment regimens will reduce or eliminate these types of impairments.

  16. Confirmation of childhood acute lymphoblastic leukemia variants, ARID5B and IKZF1, and interaction with parental environmental exposures.

    Directory of Open Access Journals (Sweden)

    Tiffany-Jane Evans

    Full Text Available Genome wide association studies (GWAS have established association of ARID5B and IKZF1 variants with childhood acute lymphoblastic leukemia (ALL. Epidemiological studies suggest that environmental factors alone appear to make a relatively minor contribution to disease risk. The polygenic nature of childhood ALL predisposition together with the timing of environmental triggers may hold vital clues for disease etiology. This study presents results from an Australian GWAS of childhood ALL cases (n = 358 and population controls (n = 1192. Furthermore, we utilised family trio (n = 204 genotypes to extend our investigation to gene-environment interaction of significant loci with parental exposures before conception, and child's sex and age. Thirteen SNPs achieved genome wide significance in the population based case/control analysis; ten annotated to ARID5B and three to IKZF1. The most significant SNPs in these regions were ARID5B rs4245595 (OR 1.63, CI 1.38-1.93, P = 2.13×10(-9, and IKZF1 rs1110701 (OR 1.69, CI 1.42-2.02, p = 7.26×10(-9. There was evidence of gene-environment interaction for risk genotype at IKZF1, whereby an apparently stronger genetic effect was observed if the mother took folic acid or if the father did not smoke prior to pregnancy (respective interaction P-values: 0.04, 0.05. There were no interactions of risk genotypes with age or sex (P-values >0.2. Our results evidence that interaction of genetic variants and environmental exposures may further alter risk of childhood ALL however, investigation in a larger population is required. If interaction of folic acid supplementation and IKZF1 variants holds, it may be useful to quantify folate levels prior to initiating use of folic acid supplements.

    Benign occipital seizure syndromes are benign childhood epilepsy syndromes and are mainly of two types, Panayiotopoulos syndrome, an autonomic epilepsy and idiopathic childhood occipital epilepsy of Gastaut (ICOE-G) including the idiopathic photosensitive occipital lobe epilepsy. Although both these types are categorized as occipital seizures, they are distinct in presentation and management. They can also be tricky to diagnose as visual symptoms may not always be the presenting feature and i...

  20. Current status of total body irradiation in conditioning regimen for childhood acute lymphoblastic leukemia. Survey in the Japan Association of Childhood Leukemia Study (JACLS) Group

    International Nuclear Information System (INIS)

    We surveyed methods of total body irradiation (TB I) in conditioning regimens of stem cell transplantation (SCT) for children with acute lymphoblastic leukemia (ALL) at participating institutions of the Japan Association of Childhood Leukemia Study (JACLS) ALL-97 protocol. We obtained information about TBI from 25 institutions. Total dose of 12 Gy fractionated by four to six in two to three days for TBI was conducted in 22 of 25 institutions. High-risk patients, such as patients with Philadelphia positive ALL, received over 12 Gy in five institutions. Beam direction and patient's positioning were horizontal and lateral respectively in 15 institutions. Shielding of lung and/or eyes and boost irradiation to central nervous system and/or testis were done in 24 and 11 institutions respectively, but in various ways. We have to keep in mind that a great variety of TBI have been undergone in each institution when we intend to interpret multi-institutional trials of treatment including SCT for patients with ALL.

    We, and others, have demonstrated an in utero origin for translocations associated with childhood leukemia, with latency periods in some cases exceeding 10 years. The mechanism of generation of most of the translocations is thought to be aberrant repair following abortive apoptosis, rather than V(D)J recombination or exposure to topoisomerase II inhibitors. Folate supplementation may prevent some of the chromosome breakage leading to translocation formation. Translocations t(8;21) and t(12;21...

    Full Text Available Aspectos psicossociais em crianças com epilepsia benigna da infância com pontas centrotemporais (EBICT são objeto de controvérsias. O objetivo desta pesquisa foi estudar o desempenho escolar em crianças com EBICT. Vinte crianças foram submetidas ao Teste de Desempenho Escolar (TDE e comparadas a crianças sadias pareadas por idade e escolaridade. Foram estudadas as relações entre o TDE e a lateralidade do foco e o número de descargas ao eletrencefalograma. As crianças com EBICT tiveram, de modo significativo, mais freqüentemente do que as sadias, desempenho inferior no subteste de leitura e no escore total. As crianças com desempenho inferior em leitura apresentaram maior número de descargas do que aquelas com desempenho médio e superior. Não houve diferenças no TDE segundo a lateralidade do foco. O número de descargas, ao interferir com a função cerebral, pode ser um fator a explicar o desempenho mais baixo na leitura.Neuropsychological implications of benign childhood epilepsy with centrotemporal spikes-rolandic spikes (BECTS have not been adequately investigated. The aim of this study was to compare the results in a school performance test of patients with BECTS and normal age-matched controls. A total of 20 children with BECTS and 20 normal controls were submitted to anamnesis, clinical evaluation, Raven test, school performance test (SPT, digital electroencephalogram and quantitative electroencephalogram analysis. Comparing with normal controls, children with BECTS showed significantly lower SPT results, especially in reading test. There was an association between the higher number of rolandic spikes and inferior performance in SPT reading test. These findings suggest that discharges may be a factor in the genesis of lower performance in reading test in children with BECTS.

  8. Decrease in cerebral metabolic rate of glucose after high-dose methotrexate in childhood acute lymphocytic leukemia

    International Nuclear Information System (INIS)

    We measured changes in the regional cerebral metabolic rate of glucose (rCMRGlu) using 18F-fluorodeoxyglucose and positron emission tomography for the assessment of neurotoxicity in childhood acute lymphocytic leukemia treated with high-dose methotrexate (HD-MTX) therapy. We studied 8 children with acute lymphocytic leukemia (mean age: 9.6 years) treated with HD-MTX (200 mg/kg or 2,000 mg/M2) therapy. CMRGlu after HD-MTX therapy was most reduced (40%) in the patient who had central nervous system leukemia and was treated with the largest total doses of both intrathecal MTX (IT-MTX) and HD-MTX. CMRGlu in the whole brain after HD-MTX therapy was reduced by an average of 21% (P less than 0.05). The reductions of CMRGlu in 8 patients were correlated with total doses of both IT-MTX (r = 0.717; P less than 0.05) and systemic HD-MTX (r = 0.784; P less than 0.05). CMRGlu of the cerebral cortex, especially the frontal and occipital cortex, was reduced more noticeably than that of the basal ganglia and white matter. We suggest that the measurement of changes in rCMRGlu after HD-MTX therapy is useful for detecting accumulated MTX neurotoxicity

    2012-03-01

    Full Text Available Purpose : The survival rate for childhood acute lymphoblastic leukemia (ALL has improved significantly. However, overall prognosis for the 20 to 25% of patients who relapse is poor, and allogeneic hematopoietic stem cell transplantation (HSCT offers the best chance for cure. In this study, we identified significant prognostic variables by analyzing the outcomes of allogeneic HSCT in ALL patients in second complete remission (CR. Methods : Fifty-three ALL patients (42 men, 79% who received HSCT in second CR from August 1991 to February 2009 were included (26 sibling donor HSCTs, 49%; 42 bone marrow transplantations, 79%. Study endpoints included cumulative incidence of acute and chronic graft-versus-host disease (GVHD, relapse, 1-year transplant-related mortality (TRM, disease-free survival (DFS, and overall survival (OS. Results : Cumulative incidences of acute GVHD (grade 2 or above and chronic GVHD were 45.3% and 28.5%, respectively. The estimated 5-year DFS and OS for the cohort was 45.2¡?#?.8%; and 48.3¡?#?%,; respectively. Only donor type, i.e., sibling versus unrelated, showed significant correlation with DFS in multivariate analysis (P=0.010. The rates of relapse and 1 year TRM were 28.9¡?#?.4%; and 26.4¡?#?.1%;, respectively, and unrelated donor HSCT (P=0.002 and HLA mismatch (P =0.022 were significantly correlated with increased TRM in univariate analysis. Conclusion : In this single institution study spanning more than 17 years, sibling donor HSCT was the only factor predicting a favorable result in multivariate analysis, possibly due to increased TRM resulting from unrelated donor HSCT.

  13. Controversies in the diagnosis and management of childhood acute immune thrombocytopenic purpura.

    Science.gov (United States)

    Segel, George B; Feig, Stephen A

    2009-09-01

    Acute immune thrombocytopenic purpura (ITP) occurs most commonly in young children who present with severe isolated thrombocytopenia and purpura. A marrow examination is not required unless glucocorticoids are used, lest treatment mask incipient acute lymphoblastic leukemia, but controversy exists here. The recommendations for evaluation and management remain controversial, since prospective controlled trials have not been done. There is some consensus based on experience and empiric data. Almost all children with acute ITP will recover completely without therapy. Although the various treatments may increase the platelet count, they do not influence the outcome of the illness, may increase cost, and cause significant side effects. Therefore, careful observation may be the best management option for the patient with ITP, in the absence of severe bleeding. The data available relevant to these issues are discussed. PMID:19165890

    Full Text Available Background: Childhood bacterial meningitis is a neurologic emergency that continues to kill and maims children particularly in developing countries with poor immunization coverage. Objective: This study set out to assess the hospital incidence, pattern of presentation, etiologic agents, outcome and determinants of mortality among the children admitted with bacterial meningitis at the Wesley Guild Hospital (WGH, Ilesa. Patients and Methods: We carried out a retrospective review of admitted cases of bacterial meningitis in children aged one month to 15 years at the WGH, Ilesa over a three year period by looking at the hospital records. Factors in the history and examinations were compared among survivors and those that died to determine factors significantly associated with mortality in these children. Results: Eighty-one (5.5% of the 1470 childhood admissions during the study period had bacterial meningitis. Male preponderance was observed and two-thirds of the children were infants. More cases were admitted during the wet rainy season than during the dry harmattan season. Haemophilus influenzae type B and Streptococcus pneumoniae were the leading etiologic agents and ciprofloxacin and ceftriaxone adequately cover for these organisms. Twenty-two (27.2% of the 81 children died, while 34 (42.0% survived with neurologic deficits. Children with multiple seizures, coma, neck retraction, hyponatremia, hypoglycorrhachia, turbid CSF as well as Gram positive meningitis at presentation were found to more likely to die (P < 0.05. None of these factors however independently predict mortality. Conclusion: Childhood bacterial meningitis often results in death and neurologic deficit among infants and young children admitted at the WGH, Ilesa. Children diagnosed with meningitis who in addition had multiple seizures, neck retraction and coma at presentation are at increased risk of dying.

    Data on metabolic syndrome (MS) in survivors of childhood acute lymphoblastic leukemia (ALL) from developing countries are lacking. The purpose of this single-center, uncontrolled, observational study was to assess the frequency of MS in our survivors. The survivors of ALL ≤15 years at diagnosis, who had completed therapy ≥2 years earlier, were enrolled. Anthropometric measurements (weight, height, waist circumference), biochemistry (glucose, insulin, triglycerides, high-density lipoprotein [HDL], thyroid function tests, C-reactive protein [CRP], magnesium), measurement of blood pressure, and Tanner staging were performed. MS was defined by International Diabetes Federation (IDF) and the National Cholesterol Education Program Third Adult Treatment Panel guidelines (NCEP ATP III) criteria, modified by Cook et al. (Arch Pediatr Adolesc Med. 2003;157:821-827) and Ford et al. (Diabetes Care. 2005;28:878-881). The median age of 76 survivors was 11.9 years (interquartile range [IQR]: 9.6-13.5). Twenty-four (32%) survivors were obese or overweight. The prevalence of insulin resistance (17%), hypertension (7%), hypertriglyceridemia (20%), and low HDL (37%) was comparable to the prevalence in children/adolescents in historical population-based studies from India. The prevalence of MS ranged from 1.3% to 5.2%, as per different defining criteria. Cranial radiotherapy, age at diagnosis, sex, or socioeconomic status were not risk factors for MS. The prevalence of MS in survivors of childhood ALL, at a median duration of 3 years from completion of chemotherapy, was comparable to the reference population. The prevalence of being obese or overweight was, however, greater than historical controls. PMID:26984439

    There is evidence that survivors of childhood cancers, such as acute lymphoblastic leukaemia (ALL), have increased rates of longterm skeletal muscle dysfunction. This places them at higher risk of physical restriction and functional impairment as well as potentially contributing to observed increases in cardiovascular disease and insulin resistance in later life. The mechanisms underlying these changes in skeletal muscle are unknown but chemotherapy drugs used in treatment for ALL are strong...

    Acute lymphoblastic leukemia (ALL) is the most frequent malignancy of childhood. Substantial progress on understanding the cell hierarchy within ALL bone marrow (BM) has been recorded in the last few years, suggesting that both primitive cell fractions and committed lymphoid blasts with immature stem cell-like properties contain leukemia-initiating cells. Nevertheless, the biology of the early progenitors that initiate the lymphoid program remains elusive. The aim of the present study was to ...

  4. Neurotoxicity during induction treatment of childhood acute lymphoblastic leukaemia: Two case reports

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available Introduction. During chemotherapy of acute lymphoblastic leukaemia (ALL, children sometimes exhibit neurological disturbances. Chemiotherapeutic regimens include methotrexate, administered either intravenously or via intrathecal route. Although multiple drugs are used in addition to methotrexate, the acute neurotoxicity reported in patients is usually attributed to methotrexate. The acute neurotoxicity usually results in stroke-like symptoms such as aphasia, weakness, sensory deficits, ataxia and seizures. Outline of Cases. From 2002 until January 2008, 32 children with ALL were diagnosed and treated at the Children's Hospital in Niš. The patients' age ranged from 1.5 to 16 years. They were treated in accordance with the protocol ALL IC-BFM 2002 (ALL Intercontinental Berlin Frankfurt M'nster 2002. Two of the patients (6.25% exhibited neurotoxicity. After the occurrence of neurological symptoms, the patients were ophthalmologically and neurologically examined. In addition, the magnetic resonance (MR imaging, computerized tomography and electroencephalography were applied. The paper presents two patients, aged 9 and 15 years respectively, who exhibited acute neurotoxicity - methotrexate encephalopathy during ALL treatment. Both patients had tonic-clonic seizures and neurological symptoms in the course of the induction therapy. Neurotoxicity occurred 7 days after the third, and 3 days after the fourth intrathecal methotrexate therapy. MR images confirmed multi-focal morphological changes of brain density in one of the patients, while the other patient had normal CT reading. Even though the development significantly differed, the changes were reversible in both patients. Conclusion. The neurotoxicity in patients with ALL can be combined with significant structural changes of the brain, but also morphological changes can be absent. Several questions concerning aetiology and treatment of neurological events are raised.

    Recent studies have reported that the absolute lymphocyte count (ALC) during induction therapy is predictive of treatment outcome in de novo acute lymphoblastic leukemia (ALL); however, the significance of ALC on outcomes remains controversial. In the present study, we assessed the significance of ALC at day 29 (ALC-29), the end of induction therapy, on outcomes in our Japanese cohort. The outcomes of 141 patients aged ≤18 years with newly diagnosed ALL who were enrolled on the JACLS ALL-02 at our hospitals were analyzed in terms of ALC-29. Patients with ALC-29 ≥750/μL (n = 81) had a superior 5-year EFS (95.2 ± 2.7 vs 84.3 ± 4.8 %, P = 0.016) and OS (100 vs 87.0 ± 4.7 %, P = 0.0062). A multivariate analysis identified ALC-29 ≥750/μL as a significant predictor of improved EFS and OS after controlling for confounding factors. A multiple linear regression model revealed a significant inverse relationship between the percentage of blasts in bone marrow on day 15 and ALC-29 (P = 0.005). These results indicate that ALC is a simple prognostic factor in childhood ALL, and, thus, has the potential to refine current risk algorithms. PMID:26440971

    A 24-year-old Japanese man with a history of acute lymphoblastic leukemia, which occurred during childhood, developed malignant fibrous histiocytoma of his left knee. His past history revealed that he had undergone leukemic blast cell invasion of the left knee and subsequent radiation therapy 9 years ago. The total radiation doses for the upper part of the left tibia and the lower part of the left femur were 60 Gy and 40 Gy, respectively. Neither distant metastasis nor a relapse of leukemia occurred. A curative resection of the left femur with a noninvasive margin was performed. Adjuvant chemotherapy including high-dose methotrexate was given successfully before and after surgery; this was followed by relapse-free survival for 3 years. The nature of postirradiation malignant fibrous histiocytoma is highly aggressive. When a patient complains of persistent symptoms in a previously irradiated field, the possibility of this tumor must be taken into account. The importance of early diagnosis cannot be over-emphasized. (author)

    International Nuclear Information System (INIS)

    Desmoplastic infantile ganglioglioma is a rare intracranial tumour of childhood that involves the cerebral cortex and the leptomeninges. We report two patients with desmoplastic infantile gangliogliomas and multiple cerebrospinal metastases. To our knowledge, only two similar cases have been reported in the published literature. Pathologically, this rare intracranial tumour shows glial and ganglionic differentiation, accompanied by an extreme desmoplastic reaction. These are low-grade neoplasms that are questionably benign.

    Clofarabine, one of the key treatment agents for refractory and relapsed acute lymphoblastic leukemia (ALL), achieves a remission rate of approximately 30% with single-agent clofarabine induction chemotherapy. However, a remission rate of approximately 50% was reported with a combination chemotherapy regimen consisting of clofarabine, etoposide, and cyclophosphamide. We treated two cases with refractory and relapsed ALL with combination chemotherapy including clofarabine; one was an induction failure but the other achieved remission. Both cases developed an infectious complication (NCI-CTCAE grade 3) and body pain with infusion. Prophylactic antibiotic and opioid infusions facilitated avoiding septic shock and pain. Further investigation of such cases is required. PMID:25501414

  13. Risk-adapted stratification and treatment of childhood acute lymphoblastic leukaemia

    International Nuclear Information System (INIS)

    Systematic enrolment of children and adolescents with acute lymphoblastic leukaemia (ALL) into clinical trials has allowed the establishment of prognostic parameters derived from initial diagnostic findings. More important, these trials have significantly contributed to the reduction of disease recurrence as much as to the reduction of acute and late side effects. Some problems that are related to the specificity of the parameters used for risk assessment were not overcome: high tumour load by white blood cell count (WBC), age and (rare) cytogenetic subtypes (e.g. t9;22) may characterise a significant proportion of children and adolescents with high-risk ALL. Most patients who will eventually relapse do not present with characteristic features at initial diagnosis. It appears feasible through careful response assessment to identify these patients at risk of relapse, who present initially without specific features. Earlier trials of the ALL-BFM (Berlin/Frankfurt/Muenster) study group and others have demonstrated that inadequate leukaemic blast reduction in the peripheral blood or bone marrow after the first few days of therapy is highly predictive of treatment failure. Using clone-specific polymerase chain reaction-based detection of minimal residual disease (MRD) as done in trial AIEOP-BFM ALL 2000 allowed a close surveillance of specific treatment elements when applied in MRD positive patients. This may facilitate innovative chemotherapy approaches and a more rational use of allogeneic haematopoietic stem cell transplantation. In addition, genetic signatures of treatment response or failure have been identified. (authors)

    Objective Acute motor axonal neuropathy (AMAN), characterized with decreased compound muscle action potentials (CMAP) and absence of demyelinating findings in electrophysiological studies, is a subtype of Guillain-Barre Syndrome (GBS). A 4 yr-old male patient presented with ascending weakness, dysarthria and dysphagia to İstanbul Dr. Lütfi Kırdar Kartal Training and Research Hospital Neurology outpatient for three days to in 2012. Dysphonia, restricted eye movements, flaccid tetraplegia and areflexia were found in neurological examination. There were motor conduction blocks in all peripheral nerves in electrophysiological studies.According to these findings the patient was diagnosed as Acute Inflammatory Demyelinating Polyradiculoneuropathy (AIDP). Reduction of CMAP amplitudes in posterior tibial nerve, absence of CMAPs in median, ulnar and peroneal nerves and loss of motor conduction blocks were found in following electrophysiological studies. According to these findings, patient was diagnosed as AMAN. Motor conduction blocks may appear in early stage of AMAN and they disappear in later examinations. That's why electrophysiological studies must be repeated in patients with GBS. PMID:27057191

  15. Childhood acute lymphoblastic leukaemia: experience from a single tertiary care facility of Pakistan

    International Nuclear Information System (INIS)

    Objective: To evaluate the demographic features, outcome and prognostic factors seen in children with acute lymphoplastic leukaemia at a tertiary care hospital. Methods: The retrospective descriptive study was conducted at Aga Khan University Hospital, Karachi, comprising data related to children below 15 years of age and treated between January 1997 and December 2006. Kaplan Meir survival curves were used to describe overall and event-free survival rates. Cox Proportional Hazards model was used to describe factors associated with death and relapse. SPSS 16 was the main statistical tool. Results: Of the total 121 children diagnosed with the condition, 79 (65.3%) were males; 86 (71.1%) patients were between 1-9 years of age; Immunophenotyping was done in 99 (81.81%) patients: 86 (87%) cases had precursor B and 13 (13.13%) had precursor T. Of the total, 106(87.6%) patients opted for treatment, while 15 (11.6%) were lost to follow-up. Besides, 26(21.7%) patients had at least one relapse; the most common site being bone marrow in 13 (50%) followed by central nervous system in 9 (36.6%). There were 20(16.5%) deaths in the sample. Infection was the most frequent cause of death. The event-free survival and overall survival was 63% (n=76) and 65% (n=79) respectively. Conclusion: Through the clinical characteristics of children with acute lymphoblastic leukamia were similar to those reported in literature, the outcomes were inferior. The high rate of infections and relapse warrant better supportive care and risk-based approach. (author)

    International Nuclear Information System (INIS)

    Objective: To investigate the association of human parvovirus B19 infection with the onset of acute lymphoblastic leukaemia and its effect on TEL-AML-1 fusion gene and the presence of mutant P53. Methods: The case-control study was conducted at Basrah Hospital for Paediatrics and Gynaecology, Basrah, Iraq, from May 2009 to April 2010. A total of 100 blood samples were collected from 40 newly diagnosed cases and 60 healthy children to serve as control matched by age and gender. Human parvovirus B19-IgG and anti-P53 antibody were detected by enzyme-linked immunosorbent assay and TEL-AML-1 fusion gene was detected by reverse transcriptase-polymerase chain reaction on extracted ribonucleic acid from fresh blood samples using specified primers. SPSS 15 was used for statistical analysis. Results: A higher proportion of human parvovirus B19-positive cases was found in leukaemic patients (n=19; 47.5%) compared to 12 (20%) in the control group (p<0.05). There was significant association between Tel-Amyl-1 translocation and human parvovirus-B19 infection as 10 (71.4%) of TEL-AML-1 translocation-positive cases had human parvovirus-B19 IgG. On the other hand, there was no association between such infections and P53 gene mutation in the patients. Conclusion: Human parvovirus-B19 infection is common in the population, with higher prevalence among leukaemic patients with significant association between human parvovirus-B19 and TEL-AML-1 fusion gene in patients of acute lymphoblastic leukaemia.

  17. Childhood proptosis

    International Nuclear Information System (INIS)

    Proptosis in children is a hallmark of orbital diseases which can present a diagnostic challenge requiring thoughtful investigation. The aim of this review is to provide the reader an overview of the subject of childhood proptosis with an emphasis on the systematic and practical approach for the work-up of proptosis in children. Use of proper imaging studies is essential for the correct diagnosis. Computed tomography is a good screening test for any space occupying lesion of the orbit. Proptosis describes eye prominence due to space occupying orbital lesions. Congenital lesions usually present in the first decade of life. Acquired orbital lesions such as lymphangiomas, orbital varix, rhabdomyosarcoma and neural tumors may present at the end of the first decade of life. Metastatic tumors to the orbit, adenocarcinoma of lacrimal gland and rapidly growing masses may present with proptosis associated with pain. Visual loss can be the presenting symptoms in the patients with optic nerve (ON) gliomas, orbital meningiomas and posteriorly located tumors. Cystic lesions of the orbit may be congenital or acquired, dermoid cysts being the most common congenital orbital lesions. Some of the vascular lesions of the orbit include capillary hemangiomas, lymphangiomas, orbital varix, and arteriovenous malformations. Inflammatory process of the orbit in children include cellulitis and pseudotumor. Neural tumors such as neurofibromas, ON gilomas and meningiomas are less common causes of proptosis in children. Rhabdomyosarcoma is the most common primary orbital malignancy in children which can present with acute proptosis and is one of the few life-threatening diseases seen initially by an ophthalmologist. Secondary orbital tumors invade the orbit from adjacent sinuses, cranium or extended from the eye itself. The most common distant metastases in children include neuroblastoma and Ewing's sarcoma. Although many orbital processes can be diagnosed based on history, clinical

    Full Text Available Childhood acute lymphoblastic leukemia (ALL blasts are characterized by inhibited apoptosis promoting fast disease progress. It is known that in chronic lymphocytic and acute myeloid leukemias the reduced apoptosis is strongly related with the activity of calpain-calpastatin system (CCS composed of cytoplasmic proteases--calpains--performing the modulatory proteolysis of key proteins involved in cell proliferation and apoptosis, and of their endogenous inhibitor--calpastatin. Here, the CCS protein abundance and activity was for the first time studied in childhood ALL blasts and in control bone marrow CD19+ B cells by semi-quantitative flow cytometry and western blotting of calpastatin fragments resulting from endogenous calpain activity. Significantly higher μ-calpain (CAPN1 gene transcription, protein amounts and activity (but not those of m-calpain, with calpastatin amount and transcription of its gene (CAST greatly varying were observed in CD19(+ ALL blasts compared to control cells. Significant inverse relation between the amount/activity of calpain and spontaneous apoptosis was noted. Patients older than 10 years (considered at higher risk displayed increased amounts and activities of blast calpain. Finally, treatment of blasts with the tripeptide calpain inhibitors II and IV significantly and in dose-dependent fashion increased the percentage of blasts entering apoptosis. Together, these findings make the CCS a potential new predictive tool and therapeutic target in childhood ALL.

Aims: To assess the therapy related serial bone marrow changes in patients of Acute Lymphoblastic Leukemia. Settings and Design: Prospective study, carried out in Lymphoma- Leukemia Lab, Department of Pathology, K.G.M.U from March 2011 to March 2012. A total of 60 cases were studied Materials and Methods: History, complete hemogram, bone marrow examination at pretherapy (Day-0, intratherapy (Day-14, and end of induction chemotherapy (Day-28 were done. Peripheral blood smears were evaluated at regular interval to assess clearance of blast cells. Statistical analysis used: The statistical analysis was done using SPSS (Statistical Package for Social Sciences Version 15.0 statistical Analysis Software. The values were represented in Number (% and Mean ± SD. The following Statistical formulas were used: Mean, standard deviation, Chi square test, Paired "t" test, Student ′t′ test, Level of significance P Results: Incidence of ALL-L1 (46.7% and ALL-L2 (53.3% was equal. ALL-L2 patients had poor survival.Day 0 (D-0 bone marrow was hypercellular with flooding of marrow by leukemic cells. High levels of tumor load at D′0′ were associated with poor survival. 14 th day of Induction phase showed significant decrease in hemoglobin and TLC as compared to D ′0′ parameters. D28 showed marrow regeneration. Cellularity, Blast%, and Leukemic Index showed significant drop from day ′0′ to day 14 due to myelosupression, whereas regeneration reflected by increased cellularity as per day 28 marrow. Lymphocytosis (>20% at end of induction chemotherapy had better survival and longer remission.Risk of mortality was directly proportional to blast clearance and was a major independent prognostic factor for achievement of complete remission. Conclusions: A bone marrow examination at the end of induction

Methods: Seven patients were treated with transurethral intraprostatic injections of sterile steam under endoscopic visualization followed by previously scheduled adenectomies. The extirpated adenomas were grossly examined followed by whole mount sectioning and staining with triphenyl-tetrazolium chloride (TTC to evaluate thermal ablation. Histology was performed after hematoxylin and eosin staining on one prostate. After review of results from the first patient cohort, an additional 15 patients with clinical benign prostatic hyperplasia were treated followed by gadolinium-enhanced magnetic resonance imaging (MRI at one week. Results: In the first patient cohort, gross examination of TTC-stained tissue showed thermal ablation in the transition zone. In addition, there was a distinct interface between viable and necrotic prostatic parenchyma. Histopathologic examination revealed TTC staining-outlined necrotic versus viable tissue. Gadolinium-enhanced MRIs in the cohort of 15 patients demonstrated lesion defects in all patients at 1 week post-procedure. Coalesced lesions were noted with a mean (± standard deviation lesion volume of 9.6±8.5 cm3. The largest lesion volume was 35.1 cm3. Ablation using vapor was rapid and remained confined to the transition zone, consistent with the thermodynamic principles of convective thermal energy transfer. Conclusion: Thermal ablation was observed in all specimens. The

    Full Text Available Transferrin receptor 1 (CD71 is a transmembrane glycoprotein responsible for cellular iron uptake. Higher expression of CD71 has been identified as a negative prognostic marker for numerous solid tumor types and for some lymphomas. The aim of this study was to evaluate CD71 expression on acute lymphoblastic leukemia (ALL cells and to follow its possible clinical correlations. Sixty one patients, aged 1–17 years and diagnosed with ALL, were enrolled in the study. CD71 expression was analyzed on the bone marrow blastic cells by flow cytometry. CD71 expression on the  eukemic blasts was diversified; in most patients, all blastic cells showed expression of CD71, but levels of expression varied. CD71 expression was statistically higher on T-lineage leukemias. Within the B lineage ALL, a significant difference in CD71 expression existed between precursor B ALL and mature B-ALL, which showed higher CD71 expression. CD71 expression positively correlated with Hgb concentration at diagnosis. Initial risk group assessment and therapy response were not correlated with CD71 expression, although disease free and overall survival times tended to be shorter in patients with B-lineage leukemias with initial high CD71 expression.

    Full Text Available Background Acute lymphoblastic leukemia (ALL is the most common malignancy in children. Chemotherapeutic drugs for ALL such as methotrexate (Mtx and doxorubicin produce reactive oxygen species (ROS, a type of free radical. The ROS can reduce levels of antioxidants in the body, including superoxide dismutase (SOD. Decreased SOD levels can cause DNA, lipid, and protein damage, which in turn may lead to adverse effects and treatment failure. Objective To determine the effect of Mtx and doxorubicin cumulative doses on SOD levels in children with ALL. Methods We conducted a retrospective cohort study in children with ALL who underwent chemotherapy in Dr. Sardjito Hospital in October 2011 who had completed the induction phase. Risk factors for decreased SOD levels were analyzed by Cox regression and hazard ratio, with a significant level of P <0.05. Results Of 40 patients enrolled, Mtx ≥ 3000 mg/m2 significantly decreased SOD levels (HR 9.959; 95%CI 2.819 to 35.183; P=0.001. However, doxorubicin ≥90 mg/m2 did not significantly decrease SOD levels (HR 0.59 95%CI 0.194 to 1.765; P=0.34. Conclusion Methotrexate is associated with decreased SOD levels in children with ALL. However, doxorubicin is not associated with decreased SOD levels in the same patient population.

    Endocrinological function was evaluated in 31 children after successful treatment of acute lymphoblastic leukaemia. All patients had received combination chemotherapy and 12-24Gy of cranial irradiation according to the German therapy protocols BFM-81, BFM-83 and BFM-86. Height, weight, bone age and pubertal development, as well as hypothalamic-pituitary function were measured. Long-term linear growth was unaffected in all patients. However, 9 patients showed subnormal serum growth hormone levels in response to pharmacological stimulation of the pituitary. All patients had normal levels of T3 and T4, but one patient showed an increased response of thyrotropin to thyrotropin releasing hormone. All prepubertal and postpubertal children demonstrated appropriate secretion of follicle-stimulation hormone (FSH) and luteinizing hormone (LH) after stimulation with LH-releasing hormone (LH-RH). 3 pubertal girls showed adequate oestradiol levels, but abnormally high levels of gonadotropins in response to LH-RH. Sexual development was normal in two of them, but the third had a late menarche and irregular menses. The significance of these findings is discussed in the context of recommendations possibly to further reduce or completely delete prophylactic cranial irradiation. PMID:1759459

  4. Meningosis prophylaxis with intrathecal /sup 198/Au-colloid and methotrexate in childhood acute lymphocytic leukemia

    International Nuclear Information System (INIS)

    Since 1972, telecobalt irradiation plus intrathecal methotrexate (ITMTX) has been successfully replaced in Jena by intrathecal colloidal radioactive gold (/sup 198/Au) plus ITMTX for meningosis prophylaxis in leukemia. Seventy-three children with acute lymphocytic leukemia (ALL) were given 1.24-4.89 mCi (45.8-181 MBq) of colloidal 198Au IT after successful initiation of remission. During cytostatic therapy, the following relapses occurred: meningosis leucaemica, five patients (6.8%); bone-marrow relapse and the meningosis leucaemica, one patient; and bone-marrow relapse, 20 patients (27.4%). In 18 children, combination chemotherapy was terminated after two and a half or three years of treatment. After that time, one meningeal relapse and six bone-marrow relapses occurred. Within the first 24 hours after application of radioactive gold, headaches, vomiting, and fever occurred in less than 10% of the children. An apathy syndrome, leukecephalopathy, or severe infections, were not observed in a single case. Radioactive gold spreads in the subarachnoid space and is phagocytized by the arachnoidea. The tumoricide effect extends selectively over the space of distribution of the latent meningosis leucaemia. The cerebral parenchyma remains unaffected by radiation. Thus, radioactive gold may be preferable to telecobalt irradiation in preventing central nervous system leukemia

  5. The development of cerebral CT changes during treatment of acute lymphocytic leukemia in childhood

    International Nuclear Information System (INIS)

    Twenty-three children with acute lymphocytic leukemia (ALL) were examined with cranial CT at least twice with a minimal interval of 10 months. The first CT was performed at the time of diagnosis in 11 children and during therapy in 12; all but two were normal on the first CT examination. These two had slight enlargement of the ventricular system and subarachnoid space at the time of diagnosis. These findings were unchanged on the second CT examinations. Seven patients, all in remission from leukemia of the central nervous system manifested abnormal findings on later CTs. Low density areas in the periventricular white matter were seen in the brains of three, with increasing subcortical calcification in one of these cases. Five children had slight enlargement of the ventricular system and subarachnoid space, especially of the basal and Sylvian cisterns. Later CT examinations in five, plus brain autopsy in two cases, revealed unchanged or progressive conditions. The CT findings have been related to the treatment and some characteristics of the disease. The frequency of CT abnormalities was higher in patients who had received therapeutic irradiation and intraventricular methotrexate treatment. The possible reasons for the CT abnormalities are discussed. (orig.)

    To assess the self-esteem of pediatric patients on chemotherapy for acute lymphoblastic leukemia (ALL) and psychological status of their parents.The psychological status of 178 children receiving chemotherapy for ALL and their parents was assessed using parenting stress index (PSI) to determine the degree of stress the parents are exposed to using parent's and child's domains. Self-esteem Scale was used to determine the psychological status of patients.The study revealed significant low level of self-esteem in 84.83% of patients. Their parents had significant psychological stress. PSI was significantly associated with parents' low sense of competence, negative attachment to their children, feeling of high restriction, high depression, poor relation to spouse, high social isolation variables of parent's domains. It was significantly associated with low distraction, negative parents' reinforcement, low acceptability, and high demanding variables of child's domains. Long duration of disease was the most detrimental factor among demographic data of the patients.Chemotherapy for ALL has a significant impact on the psychological status of both patients and their parents with high prevalence of low self-esteem in children and high degree of stress in their parents.

  8. Childhood acute pyelonephritis: comparison of power Doppler sonography and Tc-DMSA scintigraphy

    International Nuclear Information System (INIS)

    Tc 99m DMSA scintigraphy is regarded as the gold standard for the detection and localization of acute pyelonephritis (APN) in children. Power Doppler sonography (PD US) is a radiation-free and cost-effective technique that could be useful in the diagnosis of APN in children. To compare the predictive value of PD US with DMSA scintigraphy in the diagnosis of APN in children. A total of 74 neonates and children with clinical findings consistent with possible upper urinary tract infection were evaluated with PD US and DMSA scintigraphy. Children with anatomic (grey-scale) abnormalities were excluded. A total of 147 kidneys were examined within the first 48 h after the onset of symptoms. Each kidney was divided into three zones (upper, middle, and lower third). APN was diagnosed by PD US in 46 kidneys. Sensitivity and specificity for detecting APN using DMSA scintigraphy as the reference standard were 73.8% and 85.7%, respectively. There was good agreement between PD US and DMSA scintigraphy in the localization of lesions. In clinically suspected APN, PD US has acceptable specificity and sensitivity, if performed within the first 48 h and could be helpful in neonates and children under 3 months of age in whom the use of scintigraphy is generally discouraged.

    Full Text Available Since the successful introduction of all-trans-retinoic acid (ATRA and its combination with anthracycline-containing chemotherapy, the prognosis for acute promyelocytic leukemia (APL has markedly improved. With ATRA and anthracycline-based-chemotherapy, the complete remission rate is greater than 90%, and the long-term survival rate is 70&#8210;89%. Moreover, arsenic trioxide (ATO, which was introduced for APL treatment in 1994, resulted in excellent remission rates in relapsed patients with APL, and more recently, several clinical studies have been designed to explore its role in initial therapy either alone or in combination with ATRA. APL is a rare disease in children and is frequently associated with hyperleukocytosis, which is a marker for higher risk of relapse and an increased incidence of microgranular morphology. The frequency of occurrence of the promyelocytic leukemia/ retinoic acid receptor-alpha (PML/RAR?#6752;isoforms bcr 2 and bcr 3 is higher in children than in adults. Although recent clinical studies have reported comparable long-term survival rates in patients with APL, therapy for APL in children is challenging because of the risk of early death and the potential long-term cardiac toxicity resulting from the need to use high doses of anthracyclines. Additional prospective, randomized, large clinical trials are needed to address several issues in pediatric APL and to possibly minimize or eliminate the need for chemotherapy by combining ATRA and ATO. In this review article, we discuss the molecular pathogenesis, diagnostic progress, and most recent therapeutic advances in the treatment of children with APL.

    Junayet, a nine years and six months old boy was admitted to the hospital because of back pain and vertebral compression fractures. The boy had been well until two months earlier, when he began to have back pain after falling on his back along with occasional fever. The pain was intermittent initially but gradually it became constant. One month before admission, he fell again and the back pain became deteriorated. He was mildly pale, liver was palpable, skin survey revealed normal, BCG scar mark was present. He had bone pain, cervical lymphadenopathy and a tender swelling on the lumbusacral region. Two weeks before admission, the hematological findings were suggestive of leukemia of lymphoblastic type. Biochemical values were normal except high level of serum lactate dehydrogenase (LDH). Cerebrospinal fluid (CSF) examination was free of malignant cell. Skeletal survey showed diffuse osteopenia of the thoracic and lumber spine with multiple compression fracture of the vertebral bodies of D7, D8, D12 and L1, L3 and L5 with increased disc space. Radiograph of the chest also showed diffuse osteopenia of ribs. Magnetic resonance (MRI) showed uniform signal intensity in the marrow throughout the spine with compressed fracture of the same vertebrae. Bone marrow morphology study and the cytochemistry of the aspirated marrow were consistent with acute lymphoblastic leukemia (ALL-L2). Then, he was started protocol based chemotherapy for induction of remission, consolidation, high dose methotrexate and maintenance therapy. Now, he is on regular follow up with repeated hematological and radiological examinations. Following six month of chemotherapy the boy was found with significant improvement of his physical, hematological and radiological abnormalities. PMID:20046187

    Full Text Available Abstract Background Sera from children with post-varicella infections have autoantibodies that react with centrosomes in brain and tissue culture cells. We investigated the sera of children with infections and post-varicella ataxia and related conditions for reactivity to five recombinant centrosome proteins: γγ-enolase, pericentrin, ninein, PCM-1, and Mob1. Methods Sera from 12 patients with acute post-varicella ataxia, 1 with post-Epstein Barr virus (EBV ataxia, 5 with uncomplicated varicella infections, and other conditions were tested for reactivity to cryopreserved cerebellum tissue and recombinant centrosome proteins. The distribution of pericentrin in the cerebellum was studied by indirect immunofluorescence (IIF using rabbit antibodies to the recombinant protein. Antibodies to phospholipids (APL were detected by ELISA. Results Eleven of 12 children with post-varicella ataxia, 4/5 children with uncomplicated varicella infections, 1/1 with post-EBV ataxia, 2/2 with ADEM, 1/2 with neuroblastoma and ataxia, and 2/2 with cerebellitis had antibodies directed against 1 or more recombinant centrosome antigens. Antibodies to pericentrin were seen in 5/12 children with post-varicella ataxia but not in any of the other sera tested. IIF demonstrated that pericentrin is located in axons and centrosomes of cerebellar cells. APL were detected in 75% of the sera from children with post-varicella ataxia and 50% of children with varicella without ataxia and in none of the controls. Conclusion This is the first study to show the antigen specificity of anti-centrosome antibodies in children with varicella. Our data suggest that children with post-varicella ataxia have unique autoantibody reactivity to pericentrin.

Several garlic compounds have been shown to induce apoptosis of cancer cells and to alter lymphocyte function. To investigate the effect of garlic on the apoptosis of ALL cells and lymphocyte immune function, cells from newly diagnosed childhood ALL patients were cultured with several commonly used chemotherapeutic agents and several garlic compounds. Apoptosis, lymphocyte proliferation and T-cell cytokine production were determined using multiparameter flow cytometry. At concentrations of garlic compounds that did not result in significant increases in Annexin V and 7-AAD staining of normal lymphocytes, there was a significant increase in apoptosis of ALL cells with no alteration of T-cell proliferation as determined by CD25/CD69 upregulation or interferonγ, interleukin-2 or tumor necrosis factor-α intracellular cytokine production. In contrast, the presence of chemotherapeutic agents resulted in nonselective increases in both lymphocyte and ALL apoptosis and a decrease in T-cell proliferation and cytokine production. In conclusion, we show selective apoptosis of malignant cells by garlic compounds that do not alter T-cell immune function and indicate the potential therapeutic benefit of garlic compounds in the treatment of childhood ALL.Keywords: childhood precursor-B acute lymphoblastic leukemia, garlic, apoptosis, immune function, intracellular cytokines

    Comprehensive clinical studies of patients with acute megakaryoblastic leukemia (AMKL) are lacking. We performed an international retrospective study on 490 patients (age ≤18 years) with non-Down syndrome de novo AMKL diagnosed from 1989 to 2009. Patients with AMKL (median age 1.53 years) comprised 7.8% of pediatric AML. Five-year event-free (EFS) and overall survival (OS) were 43.7% ± 2.7% and 49.0% ± 2.7%, respectively. Patients diagnosed in 2000 to 2009 were treated with higher cytarabine doses and had better EFS (P = .037) and OS (P = .003) than those diagnosed in 1989 to 1999. Transplantation in first remission did not improve survival. Cytogenetic data were available for 372 (75.9%) patients: hypodiploid (n = 18, 4.8%), normal karyotype (n = 49, 13.2%), pseudodiploid (n = 119, 32.0%), 47 to 50 chromosomes (n = 142, 38.2%), and >50 chromosomes (n = 44, 11.8%). Chromosome gain occurred in 195 of 372 (52.4%) patients: +21 (n = 106, 28.5%), +19 (n = 93, 25.0%), +8 (n = 77, 20.7%). Losses occurred in 65 patients (17.5%): -7 (n = 13, 3.5%). Common structural chromosomal aberrations were t(1;22)(p13;q13) (n = 51, 13.7%) and 11q23 rearrangements (n = 38, 10.2%); t(9;11)(p22;q23) occurred in 21 patients. On the basis of frequency and prognosis, AMKL can be classified to 3 risk groups: good risk-7p abnormalities; poor risk-normal karyotypes, -7, 9p abnormalities including t(9;11)(p22;q23)/MLL-MLLT3, -13/13q-, and -15; and intermediate risk-others including t(1;22)(p13;q13)/OTT-MAL (RBM15-MKL1) and 11q23/MLL except t(9;11). Risk-based innovative therapy is needed to improve patient outcomes. PMID:26215111

    A 60-year-old man had incidental finding of a multilobular 8 × 7 × 7-cm mass identified posterior to the urinary bladder in continuity with the prostate. The man's prostate-specific antigen was 1.87, and he denied any lower urinary tract symptoms. A transrectal ultrasound-guided biopsy demonstrated benign prostatic tissue. A computed tomography-guided needle aspiration demonstrated a benign epithelium-lined cyst, likely prostatic in origin. Benign prostatic hyperplasia is a proliferation of prostatic epithelial and stromal cells. Although prostatic hyperplasia is usually restricted to the prostate gland, hyperplastic nodules occasionally protrude outside the prostate and rarely form exophytic pelvic masses. PMID:20869104

The RFC gene (SLC19A1) is located on chromosome 21, and we hypothesized that the RFC80 G>A polymorphism would affect outcome and toxicity in childhood leukemia and that this could interact...

  19. ZAP-70 as A Possible Prognostic Factor in Childhood Acute Lymphoblastic Leukemia

    International Nuclear Information System (INIS)

    Background: Zeta-chain-associated protein (ZAP- 70) is a 70kD adaptor protein that acts quickly after T cell activation to propagate signal. The role of ZAP-70 in Tcell function is well established, and in the previous years, this molecule was considered to be T-cell specific. More recent data have documented a role of ZAP-70 in B cells. Interest in ZAP-70 has grown since it has been shown, through gene expression profiling, that it is expressed in a subset of cases of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Purpose: The aim of this study was to investigate the expression of ZAP-70 in leukemic blasts of 50 newly diagnosed patients of B-lineage acute lymphoblastic leukemia (ALL), and to assess the correlation between ZAP-70 expression and various prognostic factors and outcome. Patients and Methods: This study included 50 pediatric patients with newly diagnosed B-lineage ALL. They were 28 males (56%) and 22 females (44%) presented to the Pediatric Oncology Department, National Cancer Institute, Cairo University, during the period from 2005 to 2007. The age range was 2 to 17 years with a mean of 8.58±5.8 years and median 8 years. All patients were subjected at presentation to a full clinical history and physical examination. Patients diagnosed with ALL were enrolled on St. Jude Total XV protocol: standard risk and low risk according to results of primary investigation. Immuno phenotyping was done using monoclonal antibodies which were analyzed on Coulter XL (Panel included CD1, CD2, CD3, CD4, CD5, CD7, CD8, CD10, CD19, CD22, Cytoplasmic m, anti k, anti l, CD13, CD33, anti classII MHC and TdT). Cases were considered ZAP-70 positive when exhibiting a ZAP/GAPDH (Glyceraldehyde- 3-phosphate dehydrogenase) ratio ³0.13. Results: The study revealed expression of ZAP-70 in 5/50 cases (10%). There was no statistically significant relation between ZAP-70 expression and the following: age, Total Leukocytic Count, hepatomegaly and splenomegaly. There

  2. Benign fracture versus malignant vertebral body infiltration

    International Nuclear Information System (INIS)

    MR imaging capabilities in differentiating marrow signal alterations seen in benign vertebral body compression fractures from those of malignant vertebral infiltration were assessed. Thirty-six patients, including 15 with posttraumatic vertebral compression fractures of known age, and 21 with malignant bone lesions, were imaged with MR. MR spine imaging (1.5 T) was performed with routine spin-echo sequences as well as inversion recovery (STIR), gradient-echo scans (GRASS), and chemical shift images (selective saturation technique) to obtain fat and water scans. Fat/water images enhanced differentiation between benign and malignant signal alterations. In general, patients with malignancy showed abnormal diffuse low signal intensity on fat images and corresponding increased signal on water images. Benign compression fractures showed variable patterns of signal alteration on fat/water images depending on fracture age. Old fractures showed persistent fat signal. Only very acute traumatic fractures showed increased signal on water images

    Full Text Available Abstract Introduction We report the case of a patient with a benign multicystic peritoneal mesothelioma and describe its appearance on computed tomography scans and ultrasonography, in correlation with gross clinical and pathological findings. Case presentation A 72-year-old Caucasian woman presented to our emergency department with acute abdomen signs and symptoms. A clinical examination revealed a painful palpable mass in her left abdomen. Abdominal ultrasonography and computed tomography demonstrated the presence of a large cystic mass in her left upper abdomen, adjacent to her left hemidiaphragm. The lower border of the mass extended to the upper margin of her pelvis. A complete resection of the lesion was performed. Pathological analysis showed a benign multicystic peritoneal mesothelioma. Conclusions Benign multicystic peritoneal mesothelioma is a rare lesion with a non-specific appearance on imaging. Its diagnosis always requires pathological analysis.

    International Nuclear Information System (INIS)

    Intellectual impairment in pediatric acute lymphoblastic leukemia (ALL) is thought to be caused by the effect of treatment on the central nervous system. We therefore assessed the characteristics and tendencies of patients' cognitive ability by using the K-ABC (Kaufman Assessment Battery for Children), an intelligence test. The subjects were 28 patients treated for ALL (males 18, females 10, age 4.7-12.0 years). The patients who took the K-ABC test were divided into irradiation group (15 patients who received brain irradiation as prophylactic treatment) and a non-irradiation group (13 patients whose brain was not irradiated), and evaluated the results. The K-ABC consists of a cognition processing scale and an acquisition level, and the cognition processing scale consists of a sequential processing scale and simultaneous processing scale. Patients were assessed in regard to various factors: 1. sex, 2. age of onset, 3. length of hospital stay, 4. age at the time of irradiation, 5. radiation dose, 6. score on the cognition processing scale, and multiple comparisons were made based on analysis of variance, least significant differences (1, 2, 3, 6), and the t-test (4, 5). Sequential processing ability was impaired in the patients with impaired cognitive processing in both groups. Part of simultaneous processing ability (ability to understand spatial relationships) tended to be reduced in the irradiation group in addition to the impairment in sequential processing ability, and factors 1 and 4 influenced cognitive ability in the irradiation group. The ability of girls decreased more than in boys. When children were irradiated below 4 years of age, their ability decreased even more. Regardless of whether they had received radiation therapy, all of the patients had received chemotherapy, including methotrexate, etc., and the anticancer drugs may have reduced their cognitive ability. The reduction of simultaneous processing ability may have been caused by the addition of

  5. Survival outcome following isolated central nervous system relapse treated with additional chemotherapy and craniospinal irradiation in childhood acute lymphoblastic leukemia

    International Nuclear Information System (INIS)

    Purpose: An analysis of survival outcome following isolated central nervous system (CNS) relapse treated with craniospinal irradiation (CSI) and additional chemotherapy in children with acute lymphoblastic leukemia (ALL) was conducted. Methods and Materials: Eighteen of 344 pediatric patients with ALL who attained initial complete remission on the St. Jude Children's Research Hospital 'Study XI' prospective protocol (1984-1988) developed a CNS relapse as first adverse event. Median interval to isolated CNS relapse was 7.5 months (range = 2-40 months) after achieving initial complete remission. At diagnosis, 14 of the 18 children were categorized as 'high risk' for subsequent leukemic relapse. Preventive cranial irradiation [PCI (18 Gy)] was delivered as planned to one of the 14 'high-risk' children. The other 13 'high-risk' patients experienced a CNS relapse during the first year of continuation therapy prior to week 52 of planned PCI. All four 'low-risk' patients experienced a CNS relapse beyond the first year of continuation therapy; none were scheduled to receive PCI. Following isolated CNS relapse, all 18 patients were treated on a prospective contingency of 'Study XI' trial consisting of intensified reinduction chemotherapy, weekly intrathecal methotrexate/hydrocortisone/Ara-C x 4-6 injections, craniospinal irradiation (cranium to 24.0 Gy and spine to 15.0 Gy at 1.5 Gy/fraction) and maintenance systemic therapy for a minimum of 1 year. Results: Ten of 18 patients remain in continuous complete secondary remission at 17 to 50 months post-CNS relapse. Second sites of relapse in the remaining eight children were as follows: CNS in four, bone marrow in three, and bilateral testicular in one patient. Each of these eight patients died of progressive leukemia. At a median follow-up of 40 months post-initial CNS relapse, the 3-year secondary Kaplan-Meier survival and event-free survival are 72% and 56%, respectively. Minimal long-term neurotoxicity was associated with

  7. After the chemotherapy: potential mechanisms for chemotherapy-induced delayed skeletal muscle dysfunction in survivors of acute lymphoblastic leukaemia in childhood

    2013-04-01

    Full Text Available There is evidence that survivors of childhood cancers, such as acute lymphoblastic leukaemia (ALL, have increased rates of longterm skeletal muscle dysfunction. This places them at higher risk of physical restriction and functional impairment as well as potentially contributing to observed increases in cardiovascular disease and insulin resistance in later life. The mechanisms underlying these changes in skeletal muscle are unknown but chemotherapy drugs used in treatment for ALL are strongly implicated. Normal skeletal muscle growth, development and function are dependent on correctly functioning muscle satellite cells, muscle motor neurons and muscle mitochondria. Each of these key components is potentially susceptible to damage by chemotherapy in childhood, particularly prolonged courses including repeated administration of combination chemotherapy. If this chemotherapy-induced damage is not fully reversible, impairment of satellite cells, muscle motor innervation and mitochondria could, either singly or together, lead to the emergence of delayed or persistent skeletal muscle dysfunction many years later. The known effects of individual drugs used in the treatment of ALL are outlined and the need for specific targeted studies to investigate the mechanisms underlying persistent muscle dysfunction in survivors of childhood cancers is highlighted.

Studies of ciprofloxacin as single agent prophylaxis vary widely in success rate. We conducted a double-blind, randomized study to test the effects of ciprofloxacin monotherapy as prophylaxis for sepsis and death in induction treatment of the Indonesian childhood ALL protocol.Methods: Patients were randomized to the ciprofloxacin arm (n = 58 and to the placebo arm (n = 52. Oral ciprofloxacin monotherapy or oral placebo was administered twice a day. All events during induction were recorded: toxic death, abandonment, resistant disease, and complete remission rate.Results: Of 110 patients enrolled in this study, 79 (71.8% achieved CR. In comparison to the placebo arm, the ciprofloxacin arm had lower nadir of absolute neutrophil count during induction with median of 62 (range: 5–884 versus 270 (range: 14–25,480 × 109 cells/L (P > 0.01, greater risks for experiencing fever (50.0% versus 32.7%, P = 0.07, clinical sepsis (50.0% versus 38.5%, P = 0.22, and death (18.9% versus 5.8%, P = 0.05.Conclusion: In our setting, a reduced intensity protocol in a low-income situation, the data warn against using ciprofloxacin prophylaxis during induction treatment. A lower nadir of neutrophil count and higher mortality were found in the ciprofloxacin group.Keywords: ciprofloxacin, prophylaxis, childhood acute lymphoblastic leukemia, randomized trial, low-income country

  9. Differences in meiotic recombination rates in childhood acute lymphoblastic leukemia at an MHC class II hotspot close to disease associated haplotypes.

    Full Text Available Childhood Acute Lymphoblastic Leukemia (ALL is a malignant lymphoid disease of which B-cell precursor- (BCP and T-cell- (T ALL are subtypes. The role of alleles encoded by major histocompatibility loci (MHC have been examined in a number of previous studies and results indicating weak, multi-allele associations between the HLA-DPB1 locus and BCP-ALL suggested a role for immunosusceptibility and possibly infection. Two independent SNP association studies of ALL identified loci approximately 37 kb from one another and flanking a strong meiotic recombination hotspot (DNA3, adjacent to HLA-DOA and centromeric of HLA-DPB1. To determine the relationship between this observation and HLA-DPB1 associations, we constructed high density SNP haplotypes of the 316 kb region from HLA-DMB to COL11A2 in childhood ALL and controls using a UK GWAS data subset and the software PHASE. Of four haplotype blocks identified, predicted haplotypes in Block 1 (centromeric of DNA3 differed significantly between BCP-ALL and controls (P = 0.002 and in Block 4 (including HLA-DPB1 between T-ALL and controls (P = 0.049. Of specific common (>5% haplotypes in Block 1, two were less frequent in BCP-ALL, and in Block 4 a single haplotype was more frequent in T-ALL, compared to controls. Unexpectedly, we also observed apparent differences in ancestral meiotic recombination rates at DNA3, with BCP-ALL showing increased and T-ALL decreased levels compared to controls. In silico analysis using LDsplit sotware indicated that recombination rates at DNA3 are influenced by flanking loci, including SNPs identified in childhood ALL association studies. The observed differences in rates of meiotic recombination at this hotspot, and potentially others, may be a characteristic of childhood leukemia and contribute to disease susceptibility, alternatively they may reflect interactions between ALL-associated haplotypes in this region.

    BACKGROUND: Acute lymphocytic leukemia (ALL) is the most common hematologic malignancy in children. In young children it is also largely curable, with more than 90% of afflicted children achieving long-term remission. PRAME (Preferentially expressed antigen of melanoma) gene belongs to Group 3 class I HLA-restricted widely expressed antigens in which genes encoding widely expressed tumor antigens have been detected in many normal tissues as well as in histologically different types of tumors with no preferential expression on a certain type of cancer. It has been found to be expressed in a variety of cancer cells as leukemia & lymphoma. PRAME monitoring can be useful for detection of minimal residual disease and subsequent relapses particularly those leukemias in which specific tumor markers are unavailable. Wilms’ tumor1 (WT1) gene was identified as a gene that plays an important role in normal kidney development and inactivation of its function was shown to result in the development of Wilms’ tumors in paediatric patients. Disruption of WT1 function has been implicated in the formation of many different tumor types. AIM: to study how PRAME & WT 1 genes expression patterns influence cancer susceptibility & prognosis. PATIENTS & METHODS: 50 patients with denovo childhood acute lymphoblastic leukemia, as well as 50 age and sex matched apparently healthy volunteers were genotyped for PRAME and WT1 genes expression by reverse transcription polymerase chain reaction (RT-PCR). RESULTS: PRAME gene was expressed in 34 of the patients (68%) and WT1 gene was expressed in 26 of the patients (52%). Expression of both genes was significantly higher compared to controls (P antigens (PRAME and WT1) are potential candidates for immunotherapy in childhood acute leukemia.

    Full Text Available A well-defined but rare entity of Benign Cystic Peritoneal Mesothelioma (BCPM is reported. The aetiology of this neoplasm remains obscure. The presenting features make a precise preoperative diagnosis difficult but information provided by computed tomography and cytology may help. A firm diagnosis can only come from an electronic microscopy or immunohistological examination of the tumour. Diagnostic accuracy and diligent follow up are essential because, although the tumour is considered benign, it does tend towards local recurrence. [Int J Res Med Sci 2014; 2(2.000: 762-764

  15. Benign gastric filling defect

    International Nuclear Information System (INIS)

    The gastric lesion is a common source of complaints to Orientals, however, evaluation of gastric symptoms and laboratory examination offer little specific aid in the diagnosis of gastric diseases. Thus roentgenography of gastrointestinal tract is one of the most reliable method for detail diagnosis. On double contract study of stomach, gastric filling defect is mostly caused by malignant gastric cancer, however, other benign lesions can cause similar pictures which can be successfully treated by surgery. 66 cases of benign causes of gastric filling defect were analyzed at this point of view, which was verified pathologically by endoscope or surgery during recent 7 years in Yensei University College of Medicine, Severance Hospital. The characteristic radiological picture of each disease was discussed for precise radiologic diagnosis. 1. Of total 66 cases, there were 52 cases of benign gastric tumor 10 cases of gastric varices, 5 cases of gastric bezoar, 5 cases of corrosive gastritis, 3 cases of granulomatous disease and one case of gastric hematoma. 2. The most frequent causes of benign tumors were adenomatous polyp (35/42) and the next was leiomyoma (4/42). Others were one of case of carcinoid, neurofibroma and cyst. 3. Characteristic of benign adenomatous polyp were relatively small in size, smooth surface and were observed that large size, benign polyp was frequently type IV lesion with a stalk. 4. Submucosal tumors such as leiomyoma needed differential diagnosis with polypoid malignant cancer. However, the characteristic points of differentiation was well circumscribed smooth margined filling defect without definite mucosal destruction on surface. 5. Gastric varices showed multiple lobulated filling defected especially on gastric fundus that changed its size and shape by respiration and posture of patients. Same varices lesions on esophagus and history of liver disease were helpful for easier diagnosis. 6. Gastric bezoar showed well defined movable mass

    Full Text Available Abstract Background Consumption of cured/smoked meat and fish leads to the formation of carcinogenic N-nitroso compounds in the acidic stomach. This study investigated whether consumed cured/smoked meat and fish, the major dietary resource for exposure to nitrites and nitrosamines, is associated with childhood acute leukemia. Methods A population-based case-control study of Han Chinese between 2 and 20 years old was conducted in southern Taiwan. 145 acute leukemia cases and 370 age- and sex-matched controls were recruited between 1997 and 2005. Dietary data were obtained from a questionnaire. Multiple logistic regression models were used in data analyses. Results Consumption of cured/smoked meat and fish more than once a week was associated with an increased risk of acute leukemia (OR = 1.74; 95% CI: 1.15–2.64. Conversely, higher intake of vegetables (OR = 0.55; 95% CI: 0.37–0.83 and bean-curd (OR = 0.55; 95% CI: 0.34–0.89 was associated with a reduced risk. No statistically significant association was observed between leukemia risk and the consumption of pickled vegetables, fruits, and tea. Conclusion Dietary exposure to cured/smoked meat and fish may be associated with leukemia risk through their contents of nitrites and nitrosamines among children and adolescents, and intake of vegetables and soy-bean curd may be protective.

    To identify risk variants for childhood acute lymphoblastic leukemia (ALL) we conducted a genome-wide association study of 2 case-control series, analyzing the genotypes of 291,423 tagging SNP genotypes in a total of 907 ALL cases and 2,398 controls. We identified risk loci for ALL at 7p12.2 (IKZF1, rs4132601; OR = 1.69, P = 1.20 x 10-19), 10q21.2 (ARIDB5, rs7089424; OR = 1.65, P = 6.69 x 10-19) and 14q11.2 (CEBPE, rs2239633; OR = 1.34, P = 2.88 x 10-7). The 10q21.2 (ARIDB5) risk association appears to be selective for the subset of B-cell precursor ALL with hyperdiploidy. These data show that common low-penetrance susceptibility alleles contribute to the risk of developing childhood ALL and provide novel insight into disease causation of this hematological cancer; notably all 3 risk variants map to genes involved in transcriptional regulation and differentiation of B-cell progenitors.

    Measuring left ventricular (LV) global longitudinal strain (GLS) is recommended in screening of long-term cancer survivors for cardiotoxicity. However, there are limited data on GLS in this setting, in particular in survivors with apparently normal LV function without risk factors of impaired GLS. In the present study, we measured GLS in 191 adult survivors of childhood lymphoma or acute lymphoblastic leukemia, with normal LV ejection fraction and fractional shortening (FS) and without known hypertension, diabetes mellitus, myocardial infarction, or stroke. We compared GLS in the survivors with 180 controls. Mean GLS was -19.0 ± 2.2% in the survivor group and -21.4 ± 2.0% in the controls (p cancer treatment. Survivors treated with mediastinal radiotherapy had an odds ratio of impaired GLS of 5.2 (95% confidence interval 2.2 to 12) compared with other survivors. Survivors treated with cumulative anthracycline doses >300 mg/m(2) had an odds ratio of 4.8 (95% confidence interval 1.7 to 14) of impaired GLS. In conclusion, this study demonstrates a high proportion of LV dysfunction assessed by GLS in apparently healthy adult survivors of childhood cancer. Impaired GLS was associated with previous exposure to mediastinal radiotherapy and high doses of anthracyclines. The prognostic role of measuring GLS in this specific patient population should be examined in prospective studies. PMID:27296561

We report herein a case of a 38-year-old woman who presented with multiple uterine fibroids for which hysterectomy was carried out on her. Postoperatively, she developed left-sided pleural effusion. Computed chest tomography (CT scan revealed multiple nodules in both lungs and pleurae. Histopathology of one of the pleura-based nodules revealed a neoplasm composed of interlacing fascicles of spindle cells with uniform nuclei. The tumor cells were positive for alpha-smooth muscle actin and negative for CD34 immunohistochemical stain.

    International Nuclear Information System (INIS)

    Twenty cases of infants with low density area over the frontal lobes on CT scans mimicking cortical atrophy were reported. Almost all cases showed increased intracranial pressure of slight degree associated with delayed milestones. Marginal low density over the frontal lobes disappeared and the infants developed almost normally without operations in many cases. The lesion might be called ''Infantile benign subdural effusion'' and should be treated conservatively. (author)

    Background. In pediatrics, pneumatosis intestinalis (PI) is usually due to necrotizing enterocolitis in premature newborns. Beyond infancy, PI is uncommon. ''Benign pneumatosis'' is PI in patients with few or no symptoms that resolves with conservative management. Objective. Our goal was to better characterize benign PI in children. Our investigation focused on identifying underlying risk factors, symptoms at time of diagnosis, management and outcome. Materials and methods. Available medical records and radiographs of children with pneumatosis intestinalis from 1990 to 1998 were reviewed for underlying conditions, symptoms at time of radiographs, management and outcome. Results. Thirty-seven children (mean age 4 years) were included. Thirty-two children had identifiable risk factors. Twenty -five children were immunocompromised by their underlying conditions or therapeutic regimen. Thirty-five children were managed conservatively with resolution of PI. Two patients, however, required surgery and one patient died. Conclusion. Benign pneumatosis does occur in children. The majority have underlying risk factors, most commonly related to immunosuppression. Clinical deterioration is the most useful indicator for surgical intervention. In most patients PI resolves with conservative management. (orig.)

    Full Text Available Jose ChacónOn behalf of the Racecadotril Post-authorization Record Group; Centro Clinico Profesional Caracas, Caracas, VenezuelaAbstract: Drug efficacy might differ from clinical trial results when performed in clinical daily conditions. Therefore, it is mandatory to conduct trials about effectiveness to improve external validity. This post-authorization, open-label, noncontrolled, prospective, multicenter, observational, and naturalistic trial was designed to search for factors influencing the racecadotril overall effect on childhood acute watery diarrhea in a real-world setting of Venezuela. There were 3,873 children with acute watery diarrhea treated with racecadotril, an enkephalin breakdown blocker plus oral rehydration therapy by 97 pediatricians. Evaluations were carried out daily until emission of two consecutive formed stools or absence of watery bowel movements for 24 hours. The primary end-point was time-to-relief, defined as the time from first racecadotril dose to the last watery bowel movement time. Age, gender, nursing type, nursing status during diarrhea, diarrhea severity, and co-medication were considered as factors in the statistical analysis. The primary end-point was evaluated by factors using UNIANOVA, and post-hoc tests were done. A multiple regression analysis was carried out to identify factors affecting drug performance, racecadotril effectiveness and tolerability overall assessment was searched by physicians and patients, and inter-observer agreement was evaluated by kappa statistics. The mean time-to-relief was 18.5 ± 12.5 hours [95% confidence interval 17.9–19.0] and the diarrhea severity was the only variable with significant and independent weight on racecadotril effectiveness explaining 23% of time-to-relief variance, but even in severe diarrhea cases this time was less than 24 hours. High agreement about satisfactory perception on effectiveness and tolerability was reached among physicians and patients. In

Neuroimaging studies have produced a variety of white matter findings. However, although white matter is thought to be differentially affected, previous studies have not demonstrated a discrepancy between white and gray matter function. The present study included 36 children treated for childhood leukemia with hematopoietic stem cell transplant (HCT. Their performance on neurocognitive measures traditionally thought to measure white matter was compared to performance on measures thought to measure gray matter function. Composite white and gray matter standard scores were created based on neuropsychological measures that individuals with known white or gray matter damage perform poorly. As predicted, composite white matter scores (mean = 98.1 were significantly lower (t = 2.26, p = 0.03 than composite gray matter scores (mean = 102.5. Additionally, as gray matter performance increased, the difference between gray and white matter scores increased (R = 0.353, p = 0.035. Overall, the results of this study support the current theory that white matter damage is responsible for the more subtle neurocognitive late effects resulting from treatment for childhood leukemia.Keywords: late effects of cancer treatment, leukemia, neuropsychology, white matter, brain function

    Full Text Available Abstract Background Osteomyelitis can be difficult to diagnose and there has previously not been a prospective approach to identify all children in a defined geographic area. The aim of this study was to assess the annual incidence of osteomyelitis in children, describe the patient and disease characteristics in those with acute ( Methods In a population-based Norwegian study physicians were asked to refer all children with suspected osteomyelitis. Children with osteomyelitis received follow-up at six weeks, six months and thereafter as long as clinically needed. Results The total annual incidence rate of osteomyelitis was 13 per 100 000 (acute osteomyelitis 8 and subacute osteomyelitis 5 per 100 000. The incidence was higher in patients under the age of 3 than in older children (OR 2.9, 95%: CI 2.3–3.7. The incidence of non-vertebral osteomyelitis was higher than the incidence of vertebral osteomyelitis (10 vs. 3 per 100 000; p = .002. Vertebral osteomyelitis was more frequent in girls than in boys (OR 7.0, 95%: CI 3.3–14.7. ESR ≥ 40 mm/hr had the highest positive predictive laboratory value to identify osteomyelitis patients at 26% and MRI had a positive predictive value of 85%. Long-bone infection was found in 16 (43% patients. ESR, CRP, white blood cell count, neutrophils and platelet count were higher for patients with acute osteomyelitis than for patients with subacute osteomyelitis. Subacute findings on MRI and doctor's delay were more common in subacute osteomyelitis than in acute osteomyelitis patients. Blood culture was positive in 26% of the acute osteomyelitis patients and was negative in all the subacute osteomyelitis patients. Conclusion The annual incidence of osteomyelitis in Norway remains high. ESR values and MRI scan may help to identify osteomyelitis patients and differentiate acute and subacute osteomyelitis.

    Full Text Available Minimal residual disease, or MRD, is an important prognostic indicator in childhood acute lymphoblastic leukemia. In ALL-IC-BFM 2002 study, we employed a standardized method of flow cytometry MRD monitoring for multiple centers internationally using uniformed gating, and determined the relevant MRD-based risk stratification strategies in our local patient cohort. We also evaluated a novel method of PCR MRD quantitation using peripheral blood plasma. For the bone marrow flow MRD study, patients could be stratified into 3 risk groups according to MRD level using a single time-point at day-15 (Model I (I-A: 10%, or using two time-points at day-15 and day-33 (Model II (II-A: day-15<10% and day-33<0.01%, II-B: day-15 ≥ 10% or day-33 ≥ 0.01% but not both, II-C: day-15 ≥ 10% and day-33 ≥ 0.01%, which showed significantly superior prediction of relapse (p = .00047 and <0.0001 respectively. Importantly, patients with good outcome (frequency: 56.0%, event-free survival: 90.1% could be more accurately predicted by Model II. In peripheral blood plasma PCR MRD investigation, patients with day-15-MRD ≥ 10(-4 were at a significantly higher risk of relapse (p = 0.0117. By multivariate analysis, MRD results from both methods could independently predict patients' prognosis, with 20-35-fold increase in risk of relapse for flow MRD I-C and II-C respectively, and 5.8-fold for patients having plasma MRD of ≥ 10(-4. We confirmed that MRD detection by flow cytometry is useful for prognostic evaluation in our Chinese cohort of childhood ALL after treatment. Moreover, peripheral blood plasma DNA MRD can be an alternative where bone marrow specimen is unavailable and as a less invasive method, which allows close monitoring.

    Full Text Available Objective: This retrospective study was conducted to determine the incidence of variouscomplications of Plasmodium vivax malaria based on review of case records.Methods: The case records of all confirmed cases of malaria over the period of one year (September2005–August 2006 were studied. Complete blood count, peripheral blood findings, liver and kidneyfunctions were reviewed. The results of rapid diagnostic test for malaria (OptiMAL test, DiamedAG, Switzerland were correlated with the peripheral blood smear findings in the patients in whomit was requested. All abnormal results like a positive direct Coomb’s test were noted. Findingswere clinically correlated.Results: There were 265 confirmed cases by peripheral blood examination. Of these 221 were dueto Plasmodium vivax and 41 due to P. falciparum. Two cases had mixed infection and in one casethe species could not be identified as it showed only malarial pigment. The peak incidence ofmalaria was seen in September 2005 and August 2006. The complications in P. vivax werethrombocytopenia, biochemical evidence of hepatic dysfunction, renal damage, positive DCT anddeath due to ARDS. Thrombocytopenia was seen in 213 patients with counts 3 mg/dl with normal liver enzymes. Liver enzymeswere elevated in 60 patients with seven patients showing liver enzymes level, three times the normal.Renal dysfunction was seen in 17 patients with serum creatinine ranging from 1.3–10.65 mg/dl.One patient went into acute renal failure following quinine therapy and showed red cell fragmentsin the peripheral blood. In two children DCT was positive with the peripheral smear showing RBCagglutinates around the parasitised RBC. There were three maternal deaths at about 32 weeksgestation due to ARDS. The peripheral blood smear in these patients showed WBC agglutinates.Conclusion: This paper is presented to highlight that P. vivax malaria though considered to be abenign entity can also have a severe and complicated course

  20. The Role of Type I Insulin Like Growth Factor Receptor (IGF-IR) in Adult and Childhood Acute Lymphoblastic Leukemia

    International Nuclear Information System (INIS)

    Background: Type 1 insulin like growth factor receptor (IGF-IR) is over expressed in many tumors including hematological cancers. It is a critical signaling molecule for tumor cell proliferation and survival. Data suggest that IGF-IR antibodies can effectively and specifically inhibit cancer cell growth in vitro and in vivo. Blockage of IGF-IR expression could be a promising therapeutic approach for the management of cancer patients. Aim of Work: To characterize the expression pattern of IGF-IR gene in malignant lymphoblasts of children and adults suffering from ALL in relation to clinical features at diagnosis. Patients and Methods: The expression of IGF-IR was analyzed in 60 patients with ALL, 30 childhood ALL (16 newly diagnosed and 14 in complete remission) and 30 adulthood ALL (15 newly diagnosed and 15 in complete remission) together with 20 normal age and sex matched healthy controls using a Real-Time Quantitative Reverse- Transcriptase Polymerase Chain Reaction (RTQ-PCR) to assess the possible relation, association or correlation between IGF-IR expression and ALL clinical and laboratory features at diagnosis. Results: IGF-IR was expressed in all 60 patients with ALL; the expression levels of IGF-IR were significantly higher in newly diagnosed patients than in patients in complete remission (CR) and controls (p<0.001). There were no statistically significant differences in the expression of IGF-IR between patients with different clinical and laboratory features. Conclusion: IGF-1R seems to play a crucial role in patients with ALL since it is expressed in all ALL cases (adulthood and childhood). Therefore, new therapeutic agents targeting IGF-1R may provide a better chance for those patients

  1. An animal model to study toxicity of central nervous system therapy for childhood acute lymphoblastic leukemia: Effects on growth and craniofacial proportion

    International Nuclear Information System (INIS)

    Many long term survivors of childhood acute lymphoblastic leukemia have short stature, as well as craniofacial and dental abnormalities, as side effects of central nervous system prophylactic therapy. An animal model is presented to assess these adverse effects on growth. Cranial irradiation (1000 cGy) with and without prednisolone (18 mg/kg i.p.) and methotrexate (2 mg/kg i.p.) was administered to 17- and 18-day-old Sprague-Dawley male and female rats. Animals were weighed 3 times/week. Final body weight and body length were measured at 150 days of age. Femur length and craniofacial dimensions were measured directly from the bones, using calipers. For all exposed groups there was a permanent suppression of weight gain with no catch-up growth or normal adolescent growth spurt. Body length was reduced for all treated groups, as were the ratios of body weight to body length and cranial length to body length. Animals subjected to cranial irradiation exhibited microcephaly, whereas those who received a combination of radiation and chemotherapy demonstrated altered craniofacial proportions in addition to microcephaly. Changes in growth patterns and skeletal proportions exhibited sexually dimorphic characteristics. The results indicate that cranial irradiation is a major factor in the growth failure in exposed rats, but chemotherapeutic agents contribute significantly to the outcome of growth and craniofacial dimensions

  3. Effects of radiation on testicular function in long-term survivors of childhood acute lymphoblastic leukemia: A report from the Children Cancer Study Group

    International Nuclear Information System (INIS)

    Testicular function was evaluated in 60 long-term survivors of childhood acute lymphoblastic leukemia (ALL). All the patients were treated on two consecutive Children Cancer Study Group protocols and received identical chemotherapy and either 18 or 24 Gy radiation therapy (RT) to one of the following fields: craniospinal plus 12 Gy abdominal RT including the gonads (group 1); craniospinal (group 2); or cranial (group 3). The median age at the time of their last evaluation was 14.5 years (range, 10.5 to 25.7), which took place a median of 5.0 years (range, 1 to 10.3) after discontinuing therapy. The incidence of primary germ cell dysfunction as judged by raised levels of follicle-stimulating hormone (FSH) and/or reduced testicular volume was significantly associated with field of RT; 55% of group 1, 17% of group 2, and 0% of group 3 were abnormal (P = .002). Leydig cell function, as assessed by plasma concentrations of luteinizing hormone (LH) and testosterone, and pubertal development, was unaffected in the majority of subjects regardless of RT field. These data indicate that in boys undergoing therapy for ALL, germ cell dysfunction is common following testicular irradiation and can occur following exposure to scattered irradiation from craniospinal RT. In contrast, Leydig cell function appears resistant to direct irradiation with doses as high as 12 Gy

    2013-01-01

    Full Text Available Acute lymphoblastic leukemia (ALL accounts for approximately 75% of childhood leukemia, and chemotherapy remains the mainstay therapy. Baicalein is an active flavonoid used in traditional Chinese medicine and has recently been found to have anticancer, anti-inflammatory, and antiallergic properties. This study aims to investigate the molecular apoptotic mechanisms of baicalein in CCRF-CEM leukemic cells and to evaluate the combined therapeutic efficacy of baicalein with several commonly used chemotherapeutic drugs in CCRF-CEM cells. Our results demonstrate that baicalein induces mitochondria-dependent cleavage of caspases-9 and -3 and PARP with concomitant decreases in IAP family proteins, survivin, and XIAP. Furthermore, our results present for the first time that baicalein triggers a convergence of the intrinsic and extrinsic apoptotic pathways via the death receptor-caspase 8-tBid signaling cascade in CCRF-CEM cells. In addition, we also present for the first time that the combination of baicalein and vincristine results in a synergistic therapeutic efficacy. Overall, this combination strategy is recommended for future clinical trials in the treatment of pediatric leukemia owing to baicalein’s beneficial effects in alleviating the vomiting, nausea, and skin rashes caused by chemotherapy.

    Acute lymphoblastic leukaemias (ALL) with 51-67 chromosomes are defined as high hyperdiploid (HHD) and are generally associated with good prognosis. However, several studies show heterogeneity in HHD ALL and suggest that the favourable prognosis is associated rather with higher ploidy defined by DNA index (DNAi) ≥ 1.16 or with a presence of specific single or combined trisomies. HHD ALL with DNAi < 1.16 are only rarely studied separately. Using single nucleotide polymorphism array, we analysed 89 childhood HHD ALL patients divided into groups with lower (<1.16; n = 34) and higher (≥1.16; n = 55) DNAi. We assessed treatment response, presence of secondary aberrations, mutations in RAS pathway genes and CREBBP and also gene expression profile (GEP) to reveal differences between the two subgroups. Cases with 51-54 chromosomes had DNAi 1.1-1.16 and cases with 55-67 chromosomes had DNAi ≥ 1.16. The groups with lower and higher DNAi had distinct response to early treatment and distinct GEP. The better response of the group with higher DNAi was associated with specific trisomies (trisomy of chromosome 10 or combined with trisomies 4 and/or 17). Our results suggest that cytogenetically defined HHD ALL can in fact be divided into two biologically distinguishable subgroups and that DNAi 1.16 is a relevant value to separate between the two. © 2016 Wiley Periodicals, Inc.

  6. Lymphoid Progenitor Cells from Childhood Acute Lymphoblastic Leukemia Are Functionally Deficient and Express High Levels of the Transcriptional Repressor Gfi-1

    Full Text Available Acute lymphoblastic leukemia (ALL is the most frequent malignancy of childhood. Substantial progress on understanding the cell hierarchy within ALL bone marrow (BM has been recorded in the last few years, suggesting that both primitive cell fractions and committed lymphoid blasts with immature stem cell-like properties contain leukemia-initiating cells. Nevertheless, the biology of the early progenitors that initiate the lymphoid program remains elusive. The aim of the present study was to investigate the ability of lymphoid progenitors from B-cell precursor ALL BM to proliferate and undergo multilineage differentiation. By phenotype analyses, in vitro proliferation assays, and controlled culture systems, the lymphoid differentiation potentials were evaluated in BM primitive populations from B-cell precursor ALL pediatric patients. When compared to their normal counterparts, functional stem and progenitor cell contents were substantially reduced in ALL BM. Moreover, neither B nor NK or dendritic lymphoid-cell populations developed recurrently from highly purified ALL-lymphoid progenitors, and their proliferation and cell cycle status revealed limited proliferative capacity. Interestingly, a number of quiescence-associated transcription factors were elevated, including the transcriptional repressor Gfi-1, which was highly expressed in primitive CD34+ cells. Together, our findings reveal major functional defects in the primitive hematopoietic component of ALL BM. A possible contribution of high levels of Gfi-1 expression in the regulation of the stem/progenitor cell biology is suggested.

    To elucidate the prognosis of different types of benign astrocytomas and to ascertain whether patients with partially resected benign astrocytomas, or any subtype of these, would benefit from postoperative radiotherapy, we studied retrospectively material comprising 300 patients with benign...... astrocytomas treated in the period 1956 to 1991. The pilocytic type of astrocytoma was found to have an outstandingly good prognosis and should be regarded as a distinct nosological entity. For the non-pilocytic supratentorial astrocytomas, a multivariate regression analysis showed that age, tumour site...... time of patients with non-pilocytic supratentorial benign astrocytomas. The study emphasizes the necessity of a prospective combined multicenter analysis of the effect of radiation on benign astrocytomas....

    Endobronchial localizations of benign neoplasms are met with in 24.5 per cent of the cases. Right lung localizations are more frequent. More than half of them are broadly based (57.5 per cent). In most of the cases it is a matter of nonepithelial tumours of which a greater intensity is displayed by hamartomas /7/, vascular /4/ and neurogenic /3/ neoformations. The size of endobronchial tumours varies from 1 to 10 cm. Cases measuring 1-3 cm are the most numerous. Those of the "iceberg" type appear to be larger. The size per se has a relative importance for the clinical picture. Endobronchial tumours exhibit a clear cut clinical picture, and run a clinical course in three stages, determined by the degree of bronchial obturation and longstanding of the condition. The most common symptoms are coughing /80.7 per cent/, expectoration /50.0 per cent/, rales /57.6 per cent/, dullness /38.4 per cent/ and lacking respiration /38.4 per cent/. The nosological entity by itself is less conclusive for the clinical course. The X-ray data have orientation and by no means decisive significance for the diagnosis. The "crab pincers" sign in the bronchial lumen during bronchography has a definite importance. Bronchoscopy in conjunction with biopsy is a dependable method of preoperative diagnosing. It contributes greatly to the nosological diagnosis. Even nowadays, the diagnosis of endobronchial tumours is difficult. A rather exact diagnosis can be made intraoperatively, whereas the most accurate diagnosis is established only after histological study. The treatment of endobronchial benign neoplasms is operative. The number of medium /lobectomies/ and extensive /pulmonectomies/ pulmonary resections is considerable. In case of early diagnosis and intervention, sparing resection is the naturally indicated size of operation - mainly resection and plasty of the bronchi without lobectomy. The advantages of circular resection are substantial. Reconstructive operations of "clarinet" and

  9. Complications in the central nervous system during chemotherapy for childhood acute lymphoblastic leukemia. JACLS ALL-02 study

    International Nuclear Information System (INIS)

    We evaluated central nervous system (CNS) complications treated under the ALL-02 protocol of the Japan Association of Childhood Leukemia Study (JACLS) from April 2002 to March 2005. According to National Cancer Institute (NCI) Toxicity Criteria, 17 events of grade 3 and 4 CNS complications were reported in 15 out of 541 patients. Out of these CNS complications, leukoencephalopathy was seen in 5 patients; seizure in 5; cerebrovascular disease in 3; conscious disturbance in 2; and hypertensive encephalopathy and reversible posterior leukoencephalopathy syndrome in one patient each. The complications were intensively observed during induction therapy and the last of the early phase chemotherapy. The protocol treatment was stopped or modified in most patients after CNS complications. MRI imaging demonstrated no improvement in one patient with leukoencephalopathy who developed an isolated CNS relapse, while other patients were alive and remain in their first complete remission without any neurological sequelae. Further studies will be required to analyze risk factors for CNS complications during chemotherapy not accompanied by irradiation and to establish alternative treatments after the appearance of such CNS complications.

  10. An animal model to study toxicity of central nervous system therapy for childhood acute lymphoblastic leukemia: Effects on behavior

    International Nuclear Information System (INIS)

    Central nervous system prophylactic therapy used in the treatment of acute lymphoblastic leukemia can reduce intelligence quotient scores and impair memory and attention in children. Cranial irradiation, intrathecal methotrexate, and steroids are commonly utilized in acute lymphoblastic leukemia therapy. How they induce neurotoxicity is unknown. This study employs an animal model to explore the induction of neurotoxicity. Male and female Sprague-Dawley rats at 17 and 18 days of age were administered 18 mg/kg prednisolone, 2 mg/kg methotrexate, and 1000 cGy cranial irradiation. Another 18-day-old group was administered 1000 cGy cranial irradiation but no drugs. Matching controls received saline and/or a sham exposure to radiation. All animals at 6 weeks and 4 months of age were tested for alterations in spontaneous behavior. A computer pattern recognition system automatically recorded and classified individual behavioral acts displayed during exploration of a novel environment. Measures of behavioral initiations, total time, and time structure were used to compare treated and control animals. A permanent sex-specific change in the time structure of behavior was induced by the prednisolone, methotrexate, and radiation treatment but not by radiation alone. Unlike hyperactivity, the effect consisted of abnormal clustering and dispersion of acts in a pattern indicative of disrupted development of sexually dimorphic behavior. This study demonstrates the feasibility of an animal model delineating the agent/agents responsible for the neurotoxicity of central nervous system prophylactic therapy

    20% of children suffering from high hyperdiploid acute lymphoblastic leukemia develop recurrent disease. The molecular mechanisms are largely unknown. Here, we analyzed the genetic landscape of five patients at relapse, who developed recurrent disease without prior high-risk indication using whole-exome- and whole-genome-sequencing. Oncogenic mutations of RAS pathway genes (NRAS, KRAS, FLT3, n=4) and deactivating mutations of major epigenetic regulators (CREBBP, EP300, each n=2 and ARID4B, EZH2, MACROD2, MLL2, each n=1) were prominent in these cases and virtually absent in non-recurrent cases (n=6) or other pediatric acute lymphoblastic leukemia cases (n=18). In relapse nucleotide variations were detected in cell fate determining transcription factors (GLIS1, AKNA). Structural genomic alterations affected genes regulating B-cell development (IKZF1, PBX1, RUNX1). Eleven novel translocations involved the genes ART4, C12orf60, MACROD2, TBL1XR1, LRRN4, KIAA1467, and ELMO1/MIR1200. Typically, patients harbored only single structural variations, except for one patient who displayed massive rearrangements in the context of a germline tumor suppressor TP53 mutation and a Li-Fraumeni syndrome-like family history. Another patient harbored a germline mutation in the DNA repair factor ATM. In summary, the relapse patients of our cohort were characterized by somatic mutations affecting the RAS pathway, epigenetic and developmental programs and germline mutations in DNA repair pathways.

    Chemokines play an important role in leukocyte mobilization, hematopoiesis, and angiogenesis. Tissue-specific expression of particular chemokines also influences tumor growth and metastasis. Here, the CC chemokine pulmonary and activation-regulated chemokine (PARC)/CCL18 was measured in pediatric patients with acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML). Surprisingly, PARC immunoreactivity was consistently detected in plasma from healthy donors. After purification to homogeneity, the presence of intact PARC (1–69) and processed PARC (1–68) in normal human plasma was confirmed by sequence and mass spectrometry analysis. Furthermore, PARC serum levels were significantly increased in children with T-ALL and prepreB-ALL compared to control serum samples, whereas serum levels in AML and preB-ALL patients were not significantly different from controls. In contrast, the hemofiltrate CC chemokine-1 (HCC-1)/CCL14 was not found to be a biomarker in any of these patients’ strata, whereas the cytokine interleukin-6 (IL-6) was significantly decreased in AML and prepreB-ALL. Stimulated leukocytic cell lines or lymphoblasts from patients produced IL-8/CXCL8 or macrophage inflammatory protein-1α (MIP-1α/CCL3) but not PARC, not even after IL-4 or IL-10 treatment. However, PARC was produced by superantigen or IL-4 stimulated monocytes co-cultured with lymphocytes or lymphoblastic cells. Serum PARC levels thus constitute a novel leukemia marker, possibly reflecting tumor/host cell interactions in the circulation. PMID:14578205

    Amongst 1,200 leukemie children treated between 1958 and 1971, 60 are in complete remission for more than 10 years and 100 for more than 7 years. There were 96 acute lymphoid and 4 acute myeloid leukemias. Ten patients who have relapsed in the past have not done so lately. The F/M sex ratio is 1.5. Poor prognostic features were initially absent in 2/3 of cases. In 1/3 there was associated hyperleucocytosis and/or tumours. 93 children are in remission, their treatment having been stopped for 1 to 12 years. Five children relapsed and 4 are in a second remission for more than 2 years. Two children died in remission: one from a hepatocarcinoma and one from cardiac failure. These patients have been shown to have the following: 1) normal growth; 2) normal puberty: 8 patients have been able to reproduce, giving 10 children, one with multiple malformations; 3) school achievement and later socioprofessional behaviour has been normal. The patients have often sought a medical or paramedical career. Sequelae are minimal, psychological problems being minimal in the child. With the protocols used, mean remission curve shows a plateau after 9 years and complete definitive care is achieved in 92 per cent of patients surviving at 7 years. The very distant future outlook is not known. No other malignant haematological disease has occurred but one child died from a carcinoma. PMID:6931627

    Intracranial hemorrhage (ICH) is a rare but major cause of death in immune thrombocytopenic purpura (ITP). The authors reviewed data of 1,840 patient with ITP, from 5 pediatric hematology centers in Egypt from 1997 to 2007, to study the incidence and risk factors of ICH. Ten cases of ICH were identified with a median age at presentation of 7.5 years; 4 patients had acute ITP, 2 persistent and 4 chronic. The platelet count was late referral to a specialized center. Our results suggest that treatment does not prevent ICH and that it can occur at any time during the course of the disease. Delayed referral can be considered a risk factor for unfavorable outcome of ICH, highlighting the importance of teaching sessions for patients and their parents to minimize subsequent morbidity and mortality of ICH in children with ITP.

  16. CT studies before and after CNS treatment for acute lymphoblastic leukemia and malignant non-Hodgkin's lymphoma in childhood

    International Nuclear Information System (INIS)

    CT was performed on 72 children with acute lymphoblasitc leukemia or non-Hodgkin's lymphoma. Thirty-two of these patients were investigated prior to CNS radiation and intrathecal methotrexate therapy. Ten of these patients (31%) were known to have hydrocephalic dilatation of the CSF spaces. Clinical data and subsequent observations with analysis of the CT findings show that no difference in the attenuation values of brain tissue occurs in the absence of a CNS relapse. The percentage of abnormal findings before and after therapy remains constant. The adverse late effects described in the CT literature seem principally to be damage diagnosed too late. It is questionable if the CT demonstration of dilated CSF spaces before treatment has a prognostic significance. (orig.)

The children with BECTS underwent interictal single photon emission computed tomography (SPECT and School Performance Test (SPT. Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.Esse estudo avaliou ações motoras manuais sequenciais em crianças com epilepsia focal benigna da infância com descarga centrotemporal (EBICT e comparou os resultados com o grupo controle pareado, através do teste de Lúria (punho-lado-palma.

  1. A comparative study of central nervous system irradiation and intensive chemotherapy early in remission of childhood acute lymphocytic leukemia

    International Nuclear Information System (INIS)

    A study was designed to determine whether a one-week course of intensive chemotherapy and 2400 rads craniospinal irradiation prolonged complete remission of acute lymphocytic leukemia (ALL) in children. Of 110 patients entered into the study, 104 (94%) attained complete remission, 94 of whom were available for the 2 randomizations. They were randomly assigned to receive or not receive one week of high-dosage intravenous chemotherapy and, 4 weeks later, were again randomized to receive or not receive 2400 rads cobalt-60 craniospinal irradiation. Patients randomized for no irradiation were to receive identical radiotherapy only if and when central nervous system (CNS) leukemia developed. The one week of intensive chemotherapy had no effect on the duration of remission or on the frequency or site of relapse, but irradiation had marked effect. Complete remission was terminated by CNS leukemia in only 2 of 45 children who received ''prophylactic'' craniospinal irradiation compared to 27 to 49 not irradiated. FIve of the 25 children who were given ''therapeutic'' irradiation for demonstrated CNS leukemia have already had recurrences despite continuous hematologic remission. Under the conditions of this study, the authors conclude that one week of intensive chemotherapy does not prolong remission, that 2400 rads craniospinal irradiation early in remission prevents or delays CNS leukemia and prolongs complete remission, and that once CNS leukemia develops, 2400 rads craniospinal irradiation is not sufficient to eradicate it

    Mutation status of FLT3, NPM1, CEBPA, and WT1 genes and gene expression levels of ERG, MN1, BAALC, FLT3, and WT1 have been identified as possible prognostic markers in acute myeloid leukemia (AML). We have performed a thorough prognostic evaluation of these genetic markers in patients with pediatric AML enrolled in the Nordic Society of Pediatric Hematology and Oncology (NOPHO) 1993 or NOPHO 2004 protocols. Mutation status and expression levels were analyzed in 185 and 149 patients, respectively. Presence of FLT3-internal tandem duplication (ITD) was associated with significantly inferior event-free survival (EFS), whereas presence of an NPM1 mutation in the absence of FLT3-ITD correlated with significantly improved EFS. Furthermore, high levels of ERG and BAALC transcripts were associated with inferior EFS. No significant correlation with survival was seen for mutations in CEBPA and WT1 or with gene expression levels of MN1, FLT3, and WT1. In multivariate analysis, the presence of FLT3-ITD and high BAALC expression were identified as independent prognostic markers of inferior EFS. We conclude that analysis of the mutational status of FLT3 and NPM1 at diagnosis is important for prognostic stratification of patients with pediatric AML and that determination of the BAALC gene expression level can add valuable information.

    Full Text Available Between 2007 and 2013, there were 685 events with evidence of a relationship between pesticide exposure and acute illness/injury among persons less than 18 years old in North Carolina (United States. Median age of children affected was 4.3 years (range: 0.2–17.9. Distribution by gender was similar across all age groups. One fatality and four high severity events were observed. The greatest proportion (42% of events had ocular exposures, followed by dermal (25% and inhalation (18% exposures. When more than one route of exposure occurred, dermal and ocular routes were the most common (46%. Almost all events took place indoors and 32 events involved contact with pets. Insecticides (53% and insect repellants (31% were the most frequent agents contributing to these events. Manual application of pesticides contributed to the greatest number of events (25%, while application through a pressurized can and use of a trigger pump were involved in 21% and 15% of events, respectively. Additional contributors were due to inappropriate storage of pesticides and improper use of the pesticide. These contributing factors can be removed or minimized if pesticides are stored outside the residence or out of the reach of children and pets, and adequate ventilation is ensured whenever pesticides are applied.

    SMAC-mimetics represent a targeted therapy approach to overcome apoptosis resistance in many tumors. Here, we investigated the efficacy of the SMAC-mimetic BV6 in B-cell precursor acute lymphoblastic leukemia (BCP-ALL). In ALL cell lines, intrinsic apoptosis sensitivity was associated with rapid cIAP degradation, NF-κB activation, TNF-α secretion and induction of an autocrine TNF-α-dependent cell death loop. This pattern of responsiveness was also observed upon ex vivo analysis of 40 primograft BCP-ALL samples. Treatment with BV6 induced cell death in the majority of ALL primografts including leukemias with high-risk and poor-prognosis features. Inhibition of cell death by the TNF receptor fusion protein etanercept demonstrated that BV6 activity is dependent on TNF-α. In a preclinical NOD/SCID/huALL model of high-risk ALL, marked anti-leukemia effectivity and significantly prolonged survival were observed upon BV6 treatment. Interestingly, also in vivo, intrinsic SMAC-mimetic activity was mediated by TNF-α. Importantly, BV6 increased the effectivity of conventional induction therapy including vincristine, dexamethasone and asparaginase leading to prolonged remission induction. These data suggest SMAC-mimetics as an important addendum to efficient therapy of pediatric BCP-ALL. PMID:26775704

    We used comparative genomic hybridization (CGH) to study DNA copy number changes in 71 children with acute lymphoblastic leukemia (ALL) including 50 B-lineage and 21 T-ALLs. Forty-two patients (59%) showed genomic imbalances whereby gains were more frequently observed than losses (127 vs. 29). Gains most commonly affected the entire chromosomes 21 and 10 (19.7% each), 6, 14, 18, X (15.5% each), 17 (14.1%) and 4 (11.3%). Highly hyperdiploid karyotypes (chromosome number >50) occurred more frequently in B-lineage than in T-lineage ALL (24% vs. 4.8%). In both cell lineages deletions were mainly detected on 9p (14.1%) and 12p (8.4%), and on 6q in T-lineage ALL (4.2%). These findings were compared with loss of heterozygosity (LOH) of 6q, 9p, 11q, and 12p previously performed in 56 of the 71 patients. Among 54 sites of LOH, CGH revealed losses of the respective chromosome arms in 17 LOH-positive regions (31.5%). G-banding analysis and interphase cytogenetics with subregional probes for 14 loci confirmed the presence of genomic imbalances as detected by CGH. We, therefore, conclude that, in the absence of cytogenetic data, CGH represents a suitable method for identifying hyperdiploid karyotypes as well as prognostically relevant deletions in ALL patients.

    A randomized study was done in twenty newly diagnosed children with acute lymphoblastic leukemia. Ten children were treated with Escherichia coli L-asparaginase, and ten with Erwinia chrysanthemi L-asparaginase. L-asparaginase (ASP) treatment started halfway during ALL-induction treatment with vincristine, prednisone, daunorubicin and intrathecal methotrexate. The mean activated partial thromboplastin time (APTT) level in all children demonstrated a significant fall (P II, V, VII and X stayed within the normal range, while F VIII and F IX were elevated. During the entire period of induction therapy, the ATIII activity remained within the normal range in both treatment groups. The protein C values, however, demonstrated a steady decline from 140% at start of ASP treatment to a mean of 81% and 93%, respectively, at the end of the ASP therapy in the E. coli and Erwinia group. Five of the ten children treated with E. coli ASP demonstrated protein C levels below 70% at the end of ASP therapy, opposed to none of the Erwinia treated patients (P = 0.03). We suggest that the effect of ASP resulting in decreased coagulation factor synthesis is in part counterbalanced by the effect of prednisone on the coagulation system, when ASP is administered at the end of ALL induction treatment. The overall effect of ASP either of E. coli or of Erwinia on the hemorrhagic system reveals a slight imbalance towards thrombosis, mainly because of a gradual decrease in protein C activity. This imbalance is less pronounced in the Erwinia group. PMID:8058004

    The report deals with an estimation of the volume of radiation treatment of benign diseases in Norway and gives a survey of the subjective opinion of patients regarding the result of the treatment. Reported subjective recovery after radiation treatment seems to be at the same level as recovery without treatment. For an indication of the objective effect of radiation treatment of benign diseases, the subjective effect of this treatment has to be compared with objective findings

  9. Inherent illnesses and attacks: an ethnographic study of interpretations of childhood Acute Respiratory Infections (ARIs in Manhiça, southern Mozambique

    Full Text Available Abstract Background Pneumonia is a leading cause of childhood hospitalisation and child mortality in Africa. This study explores local interpretations of Acute Respiratory Infections (ARIs, focusing on caretakers of children under five in the context of hospital care seeking. Methods The study took place in Manhiça, southern Mozambique and used Focused Ethnographic Study tools (FES including field exercises and interviews. Results Understandings of terms used to describe ARIs differed between caretakers and hospital staff. Children's sicknesses that hospital staff diagnosed as ARIs were interpreted by caretakers as intermittent "attacks" of xifuva, a permanent, inherent and incurable chest illness. Caretakers thought that it was possible to manage and treat the attacks, which were caused by immediate natural factors such as food or the weather, but not the underlying illness, which was seen as having more indirect and social causes. Explanations of illness could not be neatly separated into pluralistic categories, but were characterised by syncretism, with "lay" and "biomedical" terms and concepts intermingling in practical care-seeking interactions between caretakers and health staff. Conclusions Health promotion should take into account the syncretism involved in explanations of ARIs in the context of practical care seeking for children. In doing so, it should draw upon lay interpretations and terminologies in order to stress the importance of seeking hospital care for all xifuva-type illnesses as well as seeking care for any subsequent attacks of an already diagnosed xifuva. However, this should be undertaken with awareness that the meanings of the terms used in practical care-seeking interactions may change over time. Health communication about ARIs should therefore be ongoing and evidence-based, even if ARIs appear to be well understood.

    The immunologic features of leukemic cells at the time of 1st hematologic relapse were compared to those obtained at initial diagnosis in 128 patients (69 children and 59 adults) with acute lymphoblastic leukemia (ALL) treated at a single institution. An immunophenotypic change was observed in 59 cases (46%), more frequently in T (20/25) than in B (39/103) lineage ALL (80 vs 38%, P=0.0008), but with a similar incidence in adults and children. Of these cases, 34 (24 B- and 10 T-ALL) changed at relapse their intralineage subgroup affiliation, although no complete shift from B to T lineage ALL, or vice versa, was observed. The myeloid antigens CD13 and/or CD33 were frequently lost (2/5 cases) or acquired (12/123 cases) at relapse. In 21 cases, the immunophenotype at relapse was more undifferentiated than at diagnosis, while it was more differentiated in 13 cases. Initial treatment intensity or preceding treatment with teniposide did not affect the phenotypic profile at relapse. Complete response (CR) rate to salvage therapy and event-free survival were not influenced by the immunophenotypic shifts, nor by the presence, at relapse, of leukemic cells expressing the myeloid antigens CD13 and/or CD33. Univariate analysis suggested that prognosis after relapse was dependent on the duration of 1st CR, patients' age and immunophenotype at the time of diagnosis, with a worse outcome for patients with T lineage ALL and for patients with the less differentiated subgroup of B lineage ALL (CD19+ and CD10-). Multivariate analysis showed that only two factors, duration of 1st CR and grade of immunologic differentiation at diagnosis, have independent prognostic value in relapsed ALL. PMID:9305605

    A 28-year-old man presented with a histiocytic sarcoma of a very uncommon origin, as it had developed for several years like a benign cutaneous histiocytosis resembling generalized eruptive histiocytoma before becoming acute, with nodal and massive pulmonary involvement. Despite various chemotherapies, the patient died within 8 months. Skin biopsies showed histiocytic proliferation in the dermis and node biopsies showed histiocytic proliferation with a sinusoidal pattern. Immunohistochemical analysis, performed on paraffin-embedded sections, demonstrated strong labeling of tumoral cells for CD68 and moderate labeling for CD3 and CD4. CD30 labeling was negative. S-100 protein was positive on a Langerhans' cell reactive subpopulation. Electron microscopy confirmed the histiocytic nature of malignant cells and showed cytoplasmic inclusions such as regularly laminated bodies, dense bodies and pleomorphic inclusions. No Birbeck granules were seen. A gene rearrangement study of T-cell receptor gamma and immunoglobulin heavy chain genes showed a germline configuration. Histiocytic sarcoma is an extremely rare true histiocytic malignancy, the existence of which has been recently debated since it has often been mistaken in the past for large cell lymphomas. Such a deceptive onset as benign cutaneous histiocytosis has not been described in the literature to our knowledge. PMID:8793665

    Whipple\\'s procedure is the treatment of choice for pancreatic and periampullary malignancies. Preoperative histological confirmation of malignancy is frequently unavailable and some patients will subsequently be found to have benign disease. Here, we review our experience with Whipple\\'s procedure for patients ultimately proven to have benign disease. The medical records of all patients who underwent Whipple\\'s procedure during a 15-year period (1987-2002) were reviewed; 112 patients underwent the procedure for suspected malignancy. In eight cases, the final histology was benign (7.1%). One additional patient was known to have benign disease at resection. The mean age was 50 years (range: 30-75). The major presenting features included jaundice (five), pain (two), gastric outlet obstruction (one), and recurrent gastrointestinal haemorrhage (one). Investigations included ultrasound (eight), computerised tomography (eight), endoscopic retrograde cholangiopancreatography (seven; of these, four patients had a stent inserted and three patients had sampling for cytology), and endoscopic ultrasound (two). The pathological diagnosis included benign biliary stricture (two), chronic pancreatitis (two), choledochal cyst (one), inflammatory pseudotumour (one), cystic duodenal wall dysplasia (one), duodenal angiodysplasia (one), and granular cell neoplasm (one). There was no operative mortality. Morbidity included intra-abdominal collection (one), anastomotic leak (one), liver abscess (one), and myocardial infarction (one). All patients remain alive and well at mean follow-up of 41 months. Despite recent advances in diagnostic imaging, 8% of the patients undergoing Whipple\\'s procedure had benign disease. A range of unusual pathological entities can mimic malignancy. Accurate preoperative histological diagnosis may have allowed a less radical operation to be performed.

    Childhood acute lymphoblastic leukemia (ALL) is the most common type of childhood leukemia. Specifically, ALL is a malignant disorder of the lymphoid progenitor cells, with a peak incidence among children aged 2-5 years. The t(12;21)(p13;q22) translocation occurs in 25 % of childhood B cell precursor ALL. In this study, bone marrow samples were obtained from 165 patients with childhood ALL. We analyzed the t(12;21) translocation and other related abnormalities using the fluorescent in situ hybridization (FISH) technique with the ETV6(TEL)/RUNX1(AML1) ES dual color translocation probe. Conventional cytogenetic analyses were also performed. ETV6 and RUNX1 related chromosomal abnormalities were found in 42 (25.5 %) of the 165 patients with childhood ALL. Among these 42 patients, structural changes were detected in 33 (78.6 %) and numerical abnormalities in 9 (21.4 %). The frequency of FISH abnormalities in pediatric ALL cases were as follows: 8.5 % for t(12;21)(p13;q22) ETV6/RUNX1 fusion, 6.0 % for RUNX1 amplification, 3.0 % for tetrasomy/trisomy 21, 1.8 % for ETV6 deletion, 1.21 % for ETV6 deletion with RUNX1 amplification, 1.21 % for ETV6 amplification with RUNX1 amplification, 0.6 % for polyploidy, 0.6 % for RUNX1 deletion, and 0.6 % for diminished ETV6 signal. The most common structural abnormality was the t(12;21) translocation, followed by RUNX1 amplification and ETV6 deletion, while the most commonly observed numerical abnormality was trisomy 21.

    This note compares mortality figures for patients treated with low dose ionizing radiation for benign conditions between the 1920's and 1950's with figures available from the Japanese A-bomb survivors. X radiation for ringworm, ankylosing spondylitis and post-partum mastitis are considered. Figures for leukemia are roughly comparable between radiotherapy groups and A-bomb survivors. Figures for the increased relative risk of breast cancer in spondylitis patients were in marked contrast to bomb survivors who received comparable doses, but compatible with the increase among women given x-rays for acute post-partum mastitis in the 1940's and 1950's. This study also suggests the possibility of different time patterns of risk between different cancers. (U.K.).

  20. Cholesterol and benign prostate disease.

    Freeman, Michael R; Solomon, Keith R

    2011-01-01

    The origins of benign prostatic diseases, such as benign prostatic hyperplasia (BPH) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), are poorly understood. Patients suffering from benign prostatic symptoms report a substantially reduced quality of life, and the relationship between benign prostate conditions and prostate cancer is uncertain. Epidemiologic data for BPH and CP/CPPS are limited, however an apparent association between BPH symptoms and cardiovascular disease (CVD) has been consistently reported. The prostate synthesizes and stores large amounts of cholesterol and prostate tissues may be particularly sensitive to perturbations in cholesterol metabolism. Hypercholesterolemia, a major risk factor for CVD, is also a risk factor for BPH. Animal model and clinical trial findings suggest that agents that inhibit cholesterol absorption from the intestine, such as the class of compounds known as polyene macrolides, can reduce prostate gland size and improve lower urinary tract symptoms (LUTS). Observational studies indicate that cholesterol-lowering drugs reduce the risk of aggressive prostate cancer, while prostate cancer cell growth and survival pathways depend in part on cholesterol-sensitive biochemical mechanisms. Here we review the evidence that cholesterol metabolism plays a role in the incidence of benign prostate disease and we highlight possible therapeutic approaches based on this concept. PMID:21862201

    The coupling of energetic metallic multilayers (a.k.a. flash metal) with energetic sol-gel synthesis and processing is an entirely new approach to forming energetic devices for several DoD and DOE needs. They are also practical and commercially viable manufacturing techniques. Improved occupational safety and health, performance, reliability, reproducibility, and environmentally acceptable processing can be achieved using these methodologies and materials. The development and fielding of this technology will enhance mission readiness and reduce the costs, environmental risks and the necessity of resolving environmental concerns related to maintaining military readiness while simultaneously enhancing safety and health. Without sacrificing current performance, we will formulate new impact initiated device (IID) compositions to replace materials from the current composition that pose significant environmental, health, and safety problems associated with functions such as synthesis, material receipt, storage, handling, processing into the composition, reaction products from testing, and safe disposal. To do this, we will advance the use of nanocomposite preparation via the use of multilayer flash metal and sol-gel technologies and apply it to new small IIDs. This work will also serve to demonstrate that these technologies and resultant materials are relevant and practical to a variety of energetic needs of DoD and DOE. The goal will be to produce an IID whose composition is acceptable by OSHA, EPA, the Clean Air Act, Clean Water Act, Resource Recovery Act, etc. standards, without sacrificing current performance. The development of environmentally benign stab detonators and igniters will result in the removal of hazardous and toxic components associated with their manufacturing, handling, and use. This will lead to improved worker safety during manufacturing as well as reduced exposure of Service personnel during their storage and or use in operations. The

    Many energetic systems can be activated via mechanical means. Percussion primers in small caliber ammunition and stab detonators used in medium caliber ammunition are just two examples. Current medium caliber (20-60mm) munitions are detonated through the use of impact sensitive stab detonators. Stab detonators are very sensitive and must be small, as to meet weight and size limitations. A mix of energetic powders, sensitive to mechanical stimulus, is typically used to ignite such devices. Stab detonators are mechanically activated by forcing a firing pin through the closure disc of the device and into the stab initiating mix. Rapid heating caused by mechanically driven compression and friction of the mixture results in its ignition. The rapid decomposition of these materials generates a pressure/temperature pulse that is sufficient to initiate a transfer charge, which has enough output energy to detonate the main charge. This general type of ignition mix is used in a large variety of primers, igniters, and detonators.[1] Common primer mixes, such as NOL-130, are made up of lead styphnate (basic) 40%, lead azide (dextrinated) 20%, barium nitrate 20%, antimony sulfide 15%, and tetrazene 5%.[1] These materials pose acute and chronic toxicity hazards during mixing of the composition and later in the item life cycle after the item has been field functioned. There is an established need to replace these mixes on toxicity, health, and environmental hazard grounds. This effort attempts to demonstrate that environmentally acceptable energetic solgel coated flash metal multilayer nanocomposites can be used to replace current impact initiated devices (IIDs), which have hazardous and toxic components. Successful completion of this project will result in IIDs that include innocuous compounds, have sufficient output energy for initiation, meet current military specifications, are small, cost competitive, and perform as well as or better than current devices. We expect flash

    Patients will experience a wide range of skin growths and changes over their lifetime. Family physicians should be able to distinguish potentially malignant from benign skin tumors. Most lesions can be diagnosed on the basis of history and clinical examination. Lesions that are suspicious for malignancy, those with changing characteristics, symptomatic lesions, and those that cause cosmetic problems may warrant medical therapy, a simple office procedure (e.g., excision, cryosurgery, laser ablation), or referral. Acrochordons are extremely common, small, and typically pedunculated benign neoplasms. Simple scissor or shave excision, electrodesiccation, or cryosurgery can be used for treatment. Sebaceous hyperplasia presents as asymptomatic, discrete, soft, pale yellow, shiny bumps on the forehead or cheeks, or near hair follicles. Except for cosmesis, they have no clinical significance. Lipomas are soft, flesh-colored nodules that are easily moveable under the overlying skin. Keratoacanthomas are rapidly growing, squamoproliferative benign tumors that resemble squamous cell carcinomas. Early simple excision is recommended. Pyogenic granuloma is a rapidly growing nodule that bleeds easily. Treatment includes laser ablation or shave excision with electrodesiccation of the base. Dermatofibromas are an idiopathic benign proliferation of fibroblasts. No treatment is required unless there is a change in size or color, bleeding, or irritation from trauma. Epidermal inclusion cysts can be treated by simple excision with removal of the cyst and cyst wall. Seborrheic keratoses and cherry angiomas generally do not require treatment. PMID:26447443

    Abstract Introduction Benign cystic mesothelioma or peritoneal inclusion cysts are rare benign abdominal tumors usually occurring in females of reproductive age. These cysts present as abdominopelvic pain or masses but are often found on imaging or incidentally at surgery. They are commonly associated with pelvic inflammatory disease, endometriosis, or ovarian cysts. We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma complicating a presentation of acute appendicitis. Case Presentation A 19-year-old Irish Caucasian woman presented with abdominal pain. Imaging suggested appendicitis with abscess formation. She was treated with antibiotics and scheduled for interval appendicectomy. At laparoscopy, an unusual cystic mass was found arising from the appendix. Histology revealed benign cystic mesothelioma. Conclusion We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma arising from the appendix and complicating a presentation of acute appendicitis. This is a benign pathology, but recurrences are not uncommon. Benign cystic mesothelioma should be included in the differential when investigating pelvic masses or abscesses associated with either appendicitis or pelvic inflammatory disease in women.

    Abstract At least in economically developed countries, in the last decades, the incidence of childhood cancer has increased and the increase is unlikely to be an artefact. Causes of the increase have not been identified: a role of preventable environmental exposures is possible. Changes have also occurred in the age distribution of acute lymphoblastic leukaemia. Currently, children with cancer can be successfully treated and cured. However, access to the best therapy differs widely among coun...

    The relationship between methylxanthine (Mx) consumption and benign breast disease was evaluated in a case-control study of 288 women with histologically confirmed benign breast lumps (203 dysplastic lesions and 85 benign tumors) and 2 groups of control women--285 patients in the hospital for acute conditions apparently unrelated to the consumption of Mx-containing beverages and 291 outpatients. The relative risk estimates of dysplastic breast lesions (fibrocystic disease), with allowance for all identified potential distorting factors, for women who drank 1-2 or 3 or more cups of coffee per day were 4.1 and 6.4, respectively, when the hospital controls were the comparison group and 2.0 and 3.7, respectively, when the outpatient controls were the comparison group. The relationship was even stronger when the total consumption of Mx-containing beverages (coffee plus tea) was considered and increased with increasing duration of use. The association was not explained by any of the major risk factors for fibrocystic breast diseases or by differences in general characteristics or other lifestyle habits between cases and controls. Mx consumption was not related to the risk of benign breast tumors (fibroadenomas). These findings support the hypothesis that Mx consumption is related to the risk of dysplastic lesions of the breast. PMID:3858587

    Contemporary treatments have resulted in 5-year event-free survival rates (EFS) of approximately 75% to 80% for childhood acute lymphoblastic leukemia (ALL). Relapses of ALL in children were more often in HR-ALL but also in very few non-HR-ALL. Thus current clinical study of ALL has focused on improving the outcome of a few subtypes of HR-ALL. Infants with ALL have a particularly high risk of treatment failure. Infant ALL Interfant-99 study found that MLL rearrangement, age younger than 6 months, poor response to a prednisone prophase and high WBC count were strong independent predictive factors for poor prognosis in infants with ALL. Treatments with hybrid protocol, including both lymphoid- and myeloid-directed treatment elements, also contain HD-MTX and high dose Ara-C ( HD-Ara-C) , will further improve the outcome for infant ALL. Children Philadelphia chromosome positive ALL ( Ph + ALL) was associated with a high relapse rate when treated with chemotherapy alone. The Children' s Oncology Group (COG) AALL0031 trial showed that the addition of tyrosine kinase inhibitors (TKIs) imatinib to intensive chemotherapy resulted in 3-year EFS more than historical control treated with chemotherapy alone. These findings create a new paradigm for integrating molecularly targeted agents with intensified chemotherapy. Children with T-ALL have had a worse outcome than with the precursor B-cell ALL previously. With more intensified chemotherapy , outcomes for children T-ALL were improved, approaching those for the precursor B-cell ALL. Recently, COG decided to treat children with T-cell ALL with separate protocols different from those for the precursor B-cell ALL, and the protocols of BFM for children with T-ALL have been the same as those of the precursor B-cell ALL. Early precursor T-cell ALL, a novel subtype of T-cell ALL, was identified by gene expression profiling, flow cytometry, and single nucleotide polymorphism array analyses. ETP-ALL, identified in 13% of T-cell ALL

  9. Benign tumours of the vulva

    International Nuclear Information System (INIS)

    Objective: To present clinicopathological analysis of benign tumours of the vulva. Patients and Methods: Thirty cases of benign tumours of vulva were studied during 2 years research period. Detailed history along with complete local and general physical examination followed by all necessary pre-operative investigations were carried out. Excision surgery was the treatment of choice in majority of cases while marsupialization was done for Bartholin's cyst. Histopathology of tumours specimen was also collected. Results: A total of 30 cases were studied. Twenty-two were cystic and 8 were solid tumours. Aggressive angiomyxoma was 10% of solid tumours and Bartholin's cyst was 46.6% of cystic tumours. Most of the patients were multipara and between 21-30 years of age. The main site of tumour was labium majus. Excision surgery for all cases and marsupialization for Bartholin's cyst was treatment of choice. Conclusion: Aggressive angiomyxoma is the commonest solid benign vulval tumour. It should be considered in the differential diagnosis of vulval mass in women of reproductive age. (author)

    1994-11-01

    We carried out MRI on 43 survivors of childhood cancer after different treatment protocols with or without cranial radiotherapy. They were free of disease, therapy having been discontinued 2-20 years earlier. Treatment had been for various malignancies, excluding brain tumours; 27 had received cranial irradiation for acute lymphoblastic leukaemia (ALL) or lymphoma. Two asymptomatic young women treated for ALL had falx meningiomas. White matter changes, low intensity foci (representing calcification or old haemorrhage) and (heterogeneous intensity focic old haemorrhages) were seen only in patients who had undergone radiotherapy. Because of the possibility of benign, potentially curable brain tumours occurring after cranial irradiation, it may be wise to carry out occasional cranial imaging in the follow-up of these patients. No routine imaging follow-up is needed after chemotherapy alone. (orig.)

    2014-02-01

    Full Text Available Benign isolated abducens palsy is a self-improving clinical entity characterized by esotropia and diplopia led by the deficiency of abduction, and accompanied by no other neurological findings. The entity may occur after experiencing minor fever episodes, viral infection. The pathophysiological mechanism of cellular injury remains unclear. Hypotheses involve damage arising from autoimmune mediation or direct viral invasion causing demyelination, localized arteritis or genetic predisposition, which could increase susceptibility to such nerve palsies. Diagnosed with benign isolated abducens palsy, a 19-month-old girl infant admitted to our outpatient clinic with an acute onset of esotropia in the right eye developing two weeks after the vaccination of diphtheria, acellular pertussis, tetanus, inactivated polio and Haemophilus influenzae type b (DTPa-IP-Hib was presented in this report.

    Full Text Available Mexico has one of the highest incidences of childhood leukemia worldwide and significantly higher mortality rates for this disease compared with other countries. One possible cause is the high prevalence of gene rearrangements associated with the etiology or with a poor prognosis of childhood acute lymphoblastic leukemia (ALL. The aims of this multicenter study were to determine the prevalence of the four most common gene rearrangements [ETV6-RUNX1, TCF3-PBX1, BCR-ABL1, and MLL rearrangements] and to explore their relationship with mortality rates during the first year of treatment in ALL children from Mexico City. Patients were recruited from eight public hospitals during 2010–2012. A total of 282 bone marrow samples were obtained at each child’s diagnosis for screening by conventional and multiplex reverse transcription polymerase chain reaction to determine the gene rearrangements. Gene rearrangements were detected in 50 (17.7% patients. ETV6-RUNX1 was detected in 21 (7.4% patients, TCF3-PBX1 in 20 (7.1% patients, BCR-ABL1 in 5 (1.8% patients, and MLL rearrangements in 4 (1.4% patients. The earliest deaths occurred at months 1, 2, and 3 after diagnosis in patients with MLL, ETV6-RUNX1, and BCR-ABL1 gene rearrangements, respectively. Gene rearrangements could be related to the aggressiveness of leukemia observed in Mexican children.

    2016-01-01

    The pharmacological treatment of benign prostatic hyperplasia (BPH) is indicated when men suffer from lower urinary tract symptoms (LUTS) but there are no absolute indications for prostate surgery or severe bladder outlet obstruction. Phytotherapy can be used in men with mild to moderate LUTS and alpha-blockers can quickly and effectively decrease the LUTS and symptomatic disease progression. Phosphodiesterase type 5 inhibitors (PDE5-I) are an alternative to alpha-blockers when men experience bothersome side effects from alpha-blockers or erectile dysfunction. If patients predominantly have bladder storage symptoms and a small prostate, muscarinic receptor antagonists are a viable treatment option. The combination of alpha-blocker plus muscarinic receptor antagonist is more efficacious in reducing LUTS than the single drugs alone. The 5 alpha-reductase inhibitors (5ARI) can significantly decrease LUTS and disease progression (e.g. acute urinary retention and need for prostate surgery) in men with larger prostates (> 30-40 ml). The combination of 5ARI plus alpha-blocker can reduce LUTS and disease progression more effectively than drug monotherapy. Combination therapy with PDE5-I (tadalafil) plus 5ARI (finasteride) reduces LUTS more substantially than 5ARI alone and, additionally, PDE5-Is reduce the sexual side effects during 5ARI treatment.

    Full Text Available One of the major causes of mortality in children younger than 5 years old is acute lower respiratory tract infections (ALRI. ALRI clinical features are cough, tachypnea, fever, coryza, chest retraction, crackles and wheeze. Increased white blood cell count with left shift might happen in pneumonia. C-reactive protein (CRP and erythrocyte sedimentation rate (ESR might rise in children with respiratory tract infections. Vitamin A deficiency is associated with severe childhood infections. The effect of vitamin A supplementation in childhood pneumonia depends on the prevalence and the level of vitamin A deficiency in the population. Some studies confirmed that retinol levels were significantly higher after recovery from acute pneumonia compared to acute phase. But there were no significant association between serum retinol level and the clinical manifestation.

    2003-03-01

    To evaluate the role of fractionated stereotactic radiotherapy (FSRT) in the management of benign brain tumors, we reviewed the clinical, and radiographic responses of patients treated. Between March 1996 and March 2002, 36 patients with benign brain tumors were treated by FSRT. The pathological diagnoses consisted of pituitary adenomas (12 patients), craniopharyngiomas (5 patients), meningiomas (10 patients), and acoustic neurinomas (9 patients). Radiotherapy doses of 25 to 35 Gy (3-6 Gy/fraction, 5-10 fractions) were prescribed to the 85-90% isodose line, depending upon the location, size and volume of the tumors. The median clinical and radiographical followup periods were 31 [range, 2-74) and 21 (range, 4-56) months, respectively. In the 35 patients that could be evaluated for their clinical response, 13 (37.1%) were considered improved, 16 (45.7%) stable and 6 (17.2%) worse. Of the 33 patients who had radiographic studies, tumor shrinkage was noted in 17 (51.5%), tumor stabilization in 13 (39.4%), and tumor progression in 3 (9,1%). Of the 17 tumor shrinkage patients, 7 [21.2%) showed a complete response, Acute radiation-induced complications occurred in 11 (30.6%) patients. FSRT is considered a safe and effective treatment method for benign brain tumors but large numbers of patients, with relatively long follow-up periods are needed to assess the exact role or effect of FSRT.

    Full Text Available Background. Benign paroxysmal torticollis (BPT is an episodic functional disorder of unknown etiology, characterized by the periods of torticollic posturing of the head, that occurs in the early months of life in healthy children. Case report. We reported two patients with BPT. In the first patient the symptoms were observed at the age of day 20, and disappeared at the age of 3 years. There were 10 episodes, of which 2 were followed by vomiting, pallor, irritability and the abnormal trunk posture. In the second patient, a 12-month-old girl, BPT started from day 15. She had 4 episodes followed by vomiting in the first year. Both girls had the normal psychomotor development. All diagnostical tests were normal. Conclusion. The recognition of BPT, as well as its clinical course may help to avoid not only unnecessary tests and the treatment, but also the anxiety of the parents.

    2016-01-01

    Benign prostatic hyperplasia (BPH) and associated lower urinary tract symptoms (LUTS) commonly affect older men. Age-related changes associated with metabolic disturbances, changes in hormone balance, and chronic inflammation may cause BPH development. The diagnosis of BPH hinges on a thorough medical history and focused physical examination, with attention to other conditions that may be causing LUTS. Digital rectal examination and urinalysis should be performed. Other testing may be considered depending on presentation of symptoms, including prostate-specific antigen, serum creatinine, urine cytology, imaging, cystourethroscopy, post-void residual, and pressure-flow studies. Many medical and surgical treatment options exist. Surgery should be reserved for patients who either have failed medical management or have complications from BPH, such as recurrent urinary tract infections, refractory urinary retention, bladder stones, or renal insufficiency as a result of obstructive uropathy.

    Objective To explore the status and significance of benign infantile convulsion with mild gastroenteritis ( BICE) in the spectrum of infantile convulsion with acute diarrhea. Methods One hundred and eighty - four cases of convulsion with acute diarrhea treated in our hospital from 2009 to 2011 were analyzed retrospectively. Results Among the 184 cases of convulsion with acute diarrhea, there were 58 cases of BICE, 49 cases of febrile seizures, 43 cases of epilepsy, 19 cases of viral encephalitis, 6 cases of hyponatremic encephalopathy, 5 cases of hypernatremic encephalopathy, 2 cases of toxic encephalopathy and 2 cases of hypocalcemie seizures. The average age of children with BICE was (17.47 ±7.90) months. The symptoms were generally mild with little or no signs of dehydration. The seizure occurred mostly during the first two days of the illness and was brief in a tetanic or clonic form. Positive rotavirus antigens were detected in 65.52% . There were no abnormal findings in the routine blood test, blood bioche-mistry, cerebrospinal fluid, cerebral computerized tomography/magnetic resonance imaging and electroencephalogram examinations. After hospitalization, the children were given fluids intravenously. Sodium pheno-barbital was administered after the first convulsion and if seizures recurred, diazepam was given intravenously. All children were fully recovered in 2 to 5 days after hospitalization. Conclusions BICE occurs frequently in the infantile convulsion with acute diarrhea and symptomatic treatment is sufficient in patient care. Thus, unnecessary medical tests and excessive treatment should be avoided.%目的 探讨轻度胃肠炎伴婴幼儿良性惊厥(BICE)在婴幼儿急性腹泻伴惊厥疾病谱中的地位及意义.方法 对2009-2011年收治的急性腹泻并有惊厥症状患儿的住院资料进行回顾性分析.结果 184例急性腹泻伴惊厥的病例中,轻度胃肠炎伴婴幼儿良性惊厥58例、热性惊厥49例、癫(痫)43

  12. Childhood leukaemia

    International Nuclear Information System (INIS)

    The debate on whether there is any link between leukaemia clusters and nuclear installations has been raging since the early eighties. A Government Inquiry found no link between childhood leukaemia and residence near Seascale, an area near British Nuclear Fuels Sellafield plant. Research in the 1980s linked childhood leukaemia to fathers' occupations prior to conception in the Seascale plant but also to workers in the iron, steel, farming and chemical industries. This article reviews research findings to date. (UK)

    2013-01-01

    Full Text Available Chromosome abnormalities that usually define high-risk acute lymphoblastic leukemia are the t(9;22/ breakpoint cluster region protein-Abelson murine leukemia viral oncogene homolog 1, hypodiploid with < 44 chromosomes and 11q23/ myeloid/lymphoid leukemia gene rearrangements. The spectrum of acute lymphoblastic leukemia genetic abnormalities is nevertheless rapidly expanding. Therefore, newly described chromosomal aberrations are likely to have an impact on clinical care in the near future. Recently, the rare intrachromosomal amplification of chromosome 21 started to be considered a high-risk chromosomal abnormality. It occurs in approximately 2-5% of pediatric patients with B-cell precursor acute lymphoblastic leukemia. This abnormality is associated with a poor outcome. Hence, an accurate detection of this abnormality is expected to become very important in the choice of appropriate therapy. In this work the clinical and molecular cytogenetic evaluation by fluorescence in situ hybridization of a child with B-cell precursor acute lymphoblastic leukemia presenting the rare intrachromosomal amplification of chromosome 21 is described.

  19. MRI appearances of benign uterine disease

    International Nuclear Information System (INIS)

    Benign uterine disease is a common entity affecting women of all ages. Ultrasound has historically been the predominant imaging method used in the evaluation of benign gynaecological disease, magnetic resonance imaging (MRI) being reserved for use in the staging of malignant uterine and cervical disease. MRI is now increasingly used in the diagnosis of benign uterine disease as well as a tool for problem-solving in cases of diagnostic dilemma. It allows detailed assessment of benign conditions, such as endometrial lesions, leiomyomas, and adenomyosis, and can be helpful in the stratification of patients to different treatment modalities, including surgical resection, uterine artery embolization, and medical therapies. In this article, we review the MRI findings in the common benign uterine diseases

    Aim: The aim of this study is to evaluate the value of the apparent diffusion coefficient (ADC) obtained in diffusion-weighted (DW) MR sequences for the differentiation between malignant and benign bone marrow lesions. Method: Forty-five patients with altered signal intensity vertebral bodies on conventional MR sequences were included. The cause of altered signal intensity was benign osteoporotic collapse in 16, acute neoplastic infiltration in 15, and infectious processes in 14; based on plain-film, CT, bone scintigraphy, conventional MR studies, biopsy or follow-up. All patients underwent isotropic DW MR images (multi-shot EPI, b values of 0 and 500 s/mm{sup 2}). Signal intensity at DW MR images was evaluated and ADC values were calculated and compared between malignancy, benign edema and infectious spondylitis. Results: Acute malignant fractures were hyperintense compared to normal vertebral bodies on the diffusion-weighted sequence, except in one patient with sclerotic metastases. Mean ADC value from benign edema (1.9 {+-} 0.39 x 10{sup -3} mm{sup 2}/s) was significantly (p < 0.0001) higher than untreated metastasic lesions (0.9 {+-} 1.3 x 10{sup -3} mm{sup 2}/s). Mean ADC value of infectious spondilytis (0.96 {+-} 0.49 x 10{sup -3} mm{sup 2}/s) was not statistically (p > 0.05) different from untreated metastasic lesions. ADC value was low (0.75 x 10{sup -3} mm{sup 2}/s) in one case of subacute benign fracture. Conclusions: ADC values are a useful complementary tool to characterize bone marrow lesions, in order to distinguish acute benign fractures from malignant or infectious bone lesions. However, ADC values are not valuable in order to differentiate malignancy from infection.

    Full Text Available Background/Aim. Nocturia often occurs in patients with benign prostate hyperplasia (BPH. The aim of the study was to investigate the frequency of nocturia in patients with BPH. Nocturia and other factors associated with it were also investigated. Methods. Forty patients with the confirmed diagnosis of BPH were studied. Transurethral and transvesical prostatectomy were performed in all the patients. Symptoms were evaluated with the International Prostate Symptom Score before, as well as three and six months after the surgery. All the results were compared with the control group. Results. There was no statistically significant difference between the patients before and after the surgery regarding nocturia. There was, however, a statistically significant difference between the operated patients and the control group regarding nocturia, as well as a statistically significant correlation between noctruia and the age of the patients in both the investigated and the control group. A correlation also existed between nocturia and the prostatic size. Conclusion. There was no statistically significant improvement in symptoms of nocturia after the surgery. It is necessary to be very careful in decision making in patients with nonabsolute indiction for surgery and isolated bothersome symptom of nocturia. Age of a patient should also be considered in the evaluation of favorable result of the surgery because of a significant correlation between noctura and the age of a patient.

    Full Text Available Abstract Background Rotavirus (RV is the commonest cause of acute gastroenteritis in infants and young children worldwide. A Quality of Life study was conducted in primary care in three European countries as part of a larger epidemiological study (SPRIK to investigate the impact of paediatric rotavirus gastroenteritis (RVGE on affected children and their parents. Methods A self-administered questionnaire was linguistically validated in Spanish, Italian and Polish. The questionnaire was included in an observational multicentre prospective study of 302 children aged Results Questionnaire responses showed that acute RVGE in a child adversely affects the parents’ daily life as well as the child. Parents of children with RVGE experience worry, distress and impact on their daily activities. RVGE of greater clinical severity (assessed by the Vesikari scale was associated with higher parental worries due to symptoms and greater changes in the child’s behaviour, and a trend to higher impact on parents’ daily activities and higher parental distress, together with a higher score on the symptom severity scale of the questionnaire. Conclusions Parents of a child with acute RVGE presenting to primary care experience worry, distress and disruptions to daily life as a result of the child’s illness. Prevention of this disease through prophylactic vaccination will improve the daily lives of parents and children.

  4. MRI of vertebral compression fractures: differentiation between benign and malignant causes

    International Nuclear Information System (INIS)

    To evaluate the MR image in the differentiation of benign and malignant lesion in compression fracture of the vertebral body. MR images of 47 benign(acute traumatic within one month : 19, chronic traumatic longer than one month or nontraumatic : 28) and 21 metastatic compression fractures were respectively reviewed in terms of margin of lesions, signal intensity, paraspinal mass formation, soft tissue change, and involvement of posterior element of vertebra. MR images of T1-(T1WI) and T2-weighted gradient echo (GE T2WI) sequence were obtained on 0.5T unit in sagittal and axial orientation with 5 mm section thickness. The margin of benign compression fracture was usually indistinct (acute fracture: 90% (17/19), chronic fracture: 68% (19/28)), whereas it was sharply delineated in metastatic compression fracture (92%, 12/13) (ρ < 0.001). Paraspinal mass was seen in both acute fraumatic and metastatic compression fractures (acute fracture: 26% (5/19), metastatic fracture:52% (11/21). Soft tissue change was seen only in acute compression fractures (58%, 11/19). Involvement of posterior element of vertebra was noted in metastatic fracture (71%, 15/21), acute fracture (32%, 6/19) and chronic fracture (7%, 2/28). On MR imaging, involvement of entire portion of a given vertebral body, sharp margin between normal and abnormal areas in partially involved cases, paraspinal mass formation, and posterior element involvement are more frequently seen in metastatic compression fractures, which are considered to be useful in differentiation between benign and malignant causes of compression fracture

    Pityriasis lichenoides (PL) is a skin condition of unclear etiology that occurs not uncommonly in childhood. It is often classified into the acute form, pityriasis lichenoides et varioliformis acuta (PLEVA), and the chronic form, pityriasis lichenoides chronica (PLC). We performed a comprehensive review of the English-language literature using the PubMed database of all cases of childhood PL reported from 1962 to 2014 and summarized the epidemiology, clinical features, treatment options, and prognosis of this condition in children. The proposed etiologies are discussed, including its association with infectious agents, medications, and immunizations and evidence for PL as a lymphoproliferative disorder. We found an average age of PL onset of 6.5 years, with a slight (61%) male predominance. We also found that PLEVA and PLC tend to occur with equal frequency and that, in many cases, there is clinical and histopathologic overlap between the two phenotypes. When systemic therapy is indicated, we propose that oral erythromycin and narrowband ultraviolet B phototherapy should be first-line treatment options for children with PL since they have been shown to be effective and well tolerated. In most cases, PL follows a benign course with no greater risk of cutaneous T-cell lymphoma, although given the rare case reports of transformation, long-term follow-up of these patients is recommended.

  12. Asbestos-related benign pleural disease review

    International Nuclear Information System (INIS)

    Benign pleural disease is the commonest manifestation of asbestos exposure encountered by radiologists. Benign pleural thickening can appear as circumscribed parietal pleural plaques or as more diffuse thickening of the visceral pleura. Benign-asbestos induced pleural effusions are a significant and under-recognized manifestation of asbestos exposure with important sequelae, such as diffuse pleural thickening which may be associated with functional impairment and for which compensation may be sought. This review concentrates on the strengths and weaknesses of chest radiography and computed tomography for the detection and characterization of benign asbestos-related pleural disease and the relevance of imaging abnormalities to compensation and functional impairment.

    Residual nonmalignant T cells in the bone marrow of patients with acute leukemias may be involved in active immune responses to leukemic cells. Here, we investigated the phenotypic signature of T cells present at diagnosis in 39 pediatric patients with acute lymphoblastic leukemia (ALL) treated within standardized ALL-BFM study protocols. Previously described age associations of lymphocyte subpopulations in the peripheral blood of healthy children were reproduced in leukemic bone marrow. Analysis of individual lymphocyte parameters and risk-associated variables using univariate linear regression models revealed a correlation of higher CD4/CD8 ratios at diagnosis with a favorable bone marrow response on day 15. Separate analysis of CD4⁺ cells with the CD4⁺CD25(hi)FoxP3⁺ T(reg) cell phenotype showed that the association was caused by non-T(reg) CD4⁺ cells. The association of higher CD4/CD8 ratios with a favorable bone marrow response on day 15 of treatment persisted in a cohort extended to 69 patients. We conclude that CD4⁺ non-T(reg) cells in leukemic bone marrow at diagnosis may have a role in early response to treatment. Prospective analysis of the CD4/CD8 ratio in a large cohort of pediatric patients is now needed. Moreover, future experiments will establish the functional role of the individual T cell subsets in immune control in pediatric ALL. PMID:24021585

    1986-12-01

    The Medical Research Council UKALL V trial for children with standard-risk acute lymphoblastic leukemia (ALL) (aged 1 to 14 years, leucocyte count less than 20 X 10(9)/L) was designed to determine whether the immunosuppressive effects of treatment could be reduced without sacrifice of antileukemic effect by alterations in the type of continuing therapy or in fractionation of cranial irradiation. Remission was achieved in 496 children on standard induction therapy, and 309 children received 24 Gy of cranial irradiation in ten to 16 fractions over 21 days, and 174 received 21 Gy in five to nine fractions over 21 days. The type of radiotherapy administered had no influence on relapse at any site or rate of death in remission. All 496 children were randomized to receive chemotherapy for 2 or 3 years with 6-mercaptopurine and methotrexate either as a continuous (group C) or a semicontinuous (group G) regimen or as a five-day pulse every 3 weeks (group I). All groups also received vincristine and prednisolone every 6 weeks. With a minimum follow-up of almost 7 years, patients in group I had significantly fewer remission deaths (P = .025) but a much higher rate of bone marrow relapse than those in group C or G (P = .002). There was an overall benefit for 3 years of chemotherapy compared with 2 years, which in contrast to previous studies, was more apparent in girls and in patients in groups C and G. Testicular relapse occurred in 37 boys, including 19 patients off therapy, with a previously negative biopsy. The overall results confirmed the prognostic significance of initial leucocyte count, even among these standard-risk patients, while girls had a superior rate of disease-free survival, but not of hematologic remission. It is concluded that, even among standard-risk patients, the prognosis is influenced by the height of the initial leukocyte count. While alterations in the fractionation of cranial irradiation do not appear to have influenced disease-free survival

    Childhood leukemia, particularly acute lymphoblastic leukemia (ALL), has long been hypothesized to be affected by abnormal immune responses to microbial challenges stemming from a lack of immune modulation in early childhood. Studies of allergies suggest that a child's immune development may be modulated by maternal immune status. We conducted a study to explore the relationship between maternal immunoglobulin E (IgE) and childhood leukemia and to investigate whether maternal immune status can influence childhood leukemia risk. Serum total and specific IgE (respiratory and food) were measured in biological mothers of 352 children (193 healthy controls and 159 leukemia cases, including 139 ALL cases) ages <8 years who were enrolled in the Northern California Childhood Leukemia Study. Odds ratios associated with maternal IgE were calculated using unconditional logistic regression adjusted for child's age, sex, race/ethnicity, and annual household income. A positive association between childhood leukemia or ALL and elevated levels of maternal serum total IgE was observed, especially among Hispanics. In addition, a positive association was observed between childhood leukemia or ALL and maternal respiratory or food IgE status. These results suggest that maternal immune function may play a crucial role in the etiology of childhood leukemia, although additional studies need to be conducted to confirm the results of this study and provide a perspective on mechanisms.

  10. Lacunar infarcts: no black holes in the brain are benign.

    2008-08-01

    Lacunar infarcts--small subcortical infarcts that result from occlusion of a single penetrating artery--account for about one quarter of all ischaemic strokes. However, there are many diagnostic pitfalls, and causes other than penetrating small vessel disease in up to one third of cases. Recent studies have shown that the prognosis after lacunar infarcts is not benign; the risk of recurrent stroke is no lower than for other ischaemic stroke subtypes, and there is an increased risk for cognitive decline, dementia and death in the long term. Furthermore, silent small vessel disease in the brain at the time of an index stroke has significant prognostic implications. In the acute phase, response to intravenous thrombolysis appears to be similar to other subtypes of ischaemic strokes. Antiplatelet drugs, careful blood pressure control, statins and modification of lifestyle risk factors are key elements in secondary prevention after lacunar infarcts. PMID:18644908

    A profound knowledge of pathogenesis and natural history enables a differentiated therapy for elderly men with lower urinary tract symptoms due to benign prostatic hyperplasia (BPH). The role of phytotherapy is still controversially discussed and, therefore, not clearly recommended by any BPH-guideline. alpha(1)-blockers are the therapy of choice for symptomatic patients at a low risk of disease progression (prostate volume 5ARI) reduce the prostate volume by 20-25% and the risk for acute urinary retention/surgery by more than 50% compared to placebo. Combination therapy (alpha(1)-blocker plus 5ARI) is superior to either monotherapy, though this advantage is only demonstrable after a prolonged treatment period (>12 months). PMID:17426942

    Benign prostatic hyperplasia (BPH) is a common cause of bothersome lower urinary tract symptoms. In the past, the aim of drug treatment was to relieve symptoms until surgery became necessary, predominantly using an α-blocker or a 5α-reductase inhibitor (5ARI) as monotherapy. • Together with improving knowledge about the pathogenesis of BPH, there is now strong evidence from large randomized trials that risk stratification and appropriate treatment with combined α-blocker/5ARI therapy can significantly reduce the risk of disease progression and avoid long-term complications such as acute urinary retention and surgery. • BPH will increasingly be managed in primary care in the future and, if new management strategies based on this evidence are to be implemented cost effectively, there is a need to introduce shared care between the primary and secondary care sectors to optimise use of resources and expertise.

    Full Text Available Childhood vitiligo is often encountered in dermatological practice. When present in infancy or early childhood, various nevoid and hereditary disorders are to be differentiated. In many cases, familial aggregation of the disease is seen and other autoimmune disorders may be associated. Segmental presentation is more common, and limited body surface area involvement is usual in this age group. Children with vitiligo often suffer from anxiety and depression because of their unusual appearance. Management of vitiligo in children is difficult as therapeutic options are restricted when compared to that in adult patients. Selection of treatment should be careful in these patients with the aim to achieve best results with minimal side effects as well as relieving patients′ and parents′ anxiety.

    Full Text Available Background: Infections remain a major cause of therapy-associated morbidity and mortality in children with acute lymphoblastic leukemia (ALL. Methods: We retrospectively analyzed the medical charts of 256 children treated for ALL under the CCLG-2008 protocol in Beijing Children′s Hospital. Results: There were 65 infectious complications in 50 patients during vincristine, daunorubicin, L-asparaginase and dexamethasone induction therapy, including microbiologically documented infections (n = 12; 18.5%, clinically documented infections (n = 23; 35.3% and fever of unknown origin (n = 30; 46.2%. Neutropenia was present in 83.1% of the infectious episodes. In all, most infections occurred around the 15 th day of induction treatment (n = 28, and no patients died of infection-associated complications. Conclusions: The infections in this study was independent of treatment response, minimal residual diseases at the end of induction therapy, gender, immunophenotype, infection at first visit, risk stratification at diagnosis, unfavorable karyotypes at diagnosis and morphologic type. The infection rate of CCLG-2008 induction therapy is low, and the outcome of patients is favorable.

    Poor prednisone response predicts an inferior outcome in pediatric acute lymphoblastic leukemia (ALL) in Berlin-Frankfurt-Münster (BFM) treatment protocols. Here, we investigated five single nucleotide polymorphisms (SNPs) in both the coding and non-coding regions of the glucocorticoid receptor (GR) gene, and analyzed their association with prednisone responsiveness in vivo in 63 pediatric patients with ALL in China. Of the five SNPs, the rs41423247 and rs7701443 polymorphisms were significantly associated with prednisone response at the allelic level (rs41423247 odds ratio [OR] = 9.58; 95% confidence interval [CI]: 1.23-74.21; p = 0.01; rs7701443 OR = 3.12; 95% CI: 1.08-9; p = 0.02). Two polymorphisms (rs6189/6190 and rs6198) were not observed in the study cohort. Haplotypes composed of CCC alleles and TCG alleles at three loci (rs7701443, Tth111I and BclI) were both associated with prednisone response (p = 0.013; p = 0.028). Our results suggested that polymorphisms in the non-coding region of the GR gene were associated with prednisone response in vivo in pediatric ALL in Han Chinese. PMID:25644744

    Ikaros is a transcriptional factor playing an essential role in lymphoid lineage development and differentiation. Ikaros gene deletions occur in some acute lymphoblastic leukemia (ALL) patients, and the most common type of abnormality is overexpression of dominant negative isoforms 6 (Ik6). Deletion of Ikaros gene has an independent association with a very poor outcome in B-cell-progenitor ALL. A new subtype of ALL characterized by the deletion of Ikaros and poor outcome has been identified by researchers, and named BCR/ABL1 like ALL.We can conclude that Ikaros may play an important role in the diagnosis and treatment of pediatric ALL.%Ikaros是淋巴细胞发育和增殖所必需的转录因子,在部分儿童急性淋巴细胞白血病(ALL)中表现为不同的缺失状态,其中以Ik6显性负相亚型过表达多见.Ikaros缺失是B祖细胞型ALL患者预后不良的一个独立危险因素.国外学者最近还确立了ALL的一种新亚型"BCR/ABL1-like ALL",同样以Ikaros缺失、预后不良为主要特征.由此推测,Ikaros对儿童ALL的诊断和治疗可能起着关键的作用.

    Full Text Available INTRODUCTION Benign Lesions of Larynx (BLL have been defined as “An abnormal mass of tissue in larynx, the growth of which exceeds and is coordinated with that of normal tissue and persists in the same excessive manner after cessation of stimuli which evoked the change.” These lesions have significant influence on vocal, social and emotional adjustments of patients. These patients present with hoarseness of voice. AIM A clinical study was undertaken at Govt. ENT Hospital, Hyderabad, for 1 year from January 2014 to December 2014. Aim of this study was to analyze age and sex distribution, symptomatology, sites of involvement, management and recurrence of benign lesions of larynx. MATERIAL AND METHODS A total of 50 patients were studied who were admitted in the hospital. Inclusion criteria: Patients with Hoarseness of Voice (HOV /change of voice, difficulty in breathing and swallowing, vocal fatigue, Foreign Body (FB sensation in the throat. Exclusion criteria: Malignancy of larynx and acute inflammatory conditions of larynx. RESULTS Benign lesions of larynx show male preponderance with M:F ratio of 2.12:1, with common age group between 31 to 40 years. Chronic vocal misuse was the predominant cause and more in professional voice users. The common lesion was Vocal Cord (VC polyp, followed by VC nodules and papillomas. Common side involved was right side. Majority of the patients had to undergo surgery. Majority of recurrence was seen in laryngeal papillomas (33.33%. CONCLUSION Benign lesions of larynx produce symptoms which vary from mild HOV to life threatening stridor. Early diagnosis leads to effective management. Males were more affected and maximum cases seen between 31 to 40 years. Chronic voice abuse, smoking, alcohol, frequent throat clearing and Laryngopharyngeal Reflux (LPR/Gastroesophageal Reflux Disease (GERD are precipitating factors. Microlaryngeal Surgery (MLS, voice rest and speech therapy offer a cost effective, useful and safe

    Full Text Available Abstract Chromosomal translocations play a crucial role in tumorigenesis, often resulting in the formation of chimeric genes or in gene deregulation through position effects. T-cell acute lymphoblastic leukemia (T-ALL is associated with a large number of such rearrangements. We report the ectopic expression of the 3' portion of EST DA926692 in the bone marrow of a childhood T-ALL case showing a t(2;11(q11.2;p15.1 translocation as the sole chromosome abnormality. The breakpoints, defined at the sequence level, mapped within HPS5 (Hermansky Pudlak syndrome 5 intron 1 at 11p15.1, and DA926692 exon 2 at 2q11.2. The translocation was accompanied by a submicroscopic inversion that brought the two genes into the same transcriptional orientation. No chimeric trancript was detected. Interestingly, Real-Time Quantitative (RQ-PCR detected, in the patient's bone marrow, expression of a 173 bp product corresponding to the 3' portion of DA926692. Samples from four T-ALL cases with a normal karyotype and normal bone marrow used as controls were negative. It might be speculated that the juxtaposition of this genomic segment to the CpG island located upstream HPS5 activated DA92669 expression. RQ-PCR analysis showed expression positivity in 6 of 23 human tissues examined. Bioinformatic analysis excluded that this small non-coding RNA is a precursor of micro-RNA, although it is conceivable that it has a different, yet unknown, functional role. To the best of our knowledge, this is the first report, in cancer, of the activation of a small non-coding RNA as a result of a chromosomal translocation.

Methods and Materials: This is a retrospective cohort study for the years 1996 to 2007. The study group comprised patients undergoing surgery in University of Sydney Endocrine Surgical Unit who had received previous head-and-neck irradiation in childhood and who were identified as having pathologic thyroid and parathyroid characteristics. Results: A total of 53 patients were identified in whom head-and-neck irradiation for the treatment of childhood malignancy had been documented. In each of the cases, thyroid disease was the primary reason for referral for surgery. Five of these patients (10%) were found to exhibit coexisting hyperparathyroidism. The latency period for hyperparathyroidism was less than 20 years in 4 of the 5 cases. There were four conventional parathyroid adenomas and one parathyroid lipoadenoma. All patients exhibited a significant decrease in postoperative calcium levels after surgery. Conclusions: To our knowledge, this is the first study to document the significant risk of hyperparathyroidism after radiation exposure for childhood malignancy. The timeframe for development of disease is much shorter than that published for individuals who have undergone irradiation for benign diseases. High doses of therapeutic radiation at a young age make childhood survivors of malignancy at especially high risk for developing hyperparathyroidism

    With the combination of immunophenotyping and molecular tests, it is still a challenge to identify the characteristics of T cell acute lymphoblastic leukemia (T-ALL) associated with distinct outcomes. This study tests the possible correlation of cellular expression of CD135 and CD117 with somatic gene mutations in T-ALL. One hundred sixty-two samples were tested, including 143 at diagnosis, 15 from T-lymphoblastic lymphoma at relapse, and four relapse samples from sequential follow-up of T-ALL. CD135 and CD117 monoclonal antibodies were included in the T-ALL panel of flow cytometry. The percentage of cells positivity and the median fluorescence intensity were correlated with gene mutational status. STIL-TAL1, TLX3, FLT3 and IL7R mutations were tested using standard techniques. STIL-TAL1 was found in 24.8%, TLX3 in 12%, IL7R in 10% and FLT3-ITD in 5% of cases. FLT3 and IL7R mutations were mutually exclusive, as were FLT3-ITD and STIL-TAL1. Associations of CD135(high) (p<0.01), CD117(intermediate/high) (p=0.02) and FLT3-ITD, CD117(low) with IL7R(mutated) (p<0.01) and CD135(high) with TLX3(pos) were observed. We conclude that the addition of CD135 and CD117 to the diagnosis can predict molecular aberrations in T-ALL settings, mainly segregating patients with FLT3-ITD, who would benefit from treatment with inhibitors of tyrosine.

    Background: It was the aim of the quality control program of the randomized trial HIT `91 (intensive chemotherapy before irradiation versus maintenance chemotherapy after irradiation) to assess prospectively the quality of neuroaxis irradiation with respect to the protocol guidelines and to evaluate acute toxicity with respect to treatment arm. Patients, Materials and Methods: Data of 134 patients undergoing irradiation of the craniospinal axis were available. Positioning aids, shielding techniques, treatment machines, choice of energy, total dose and fractionation were evaluated. A total of 651 simulation and verification films were analyzed to assess the coverage of the clinical target volume (whole brain, posterior fossa, sacral nerve roots) and deviations of field alignment between simulation and verification of first treatment. Field matching between whole brain and adjacent cranial spinal fields was analyzed with respect to site and width of junction. Acute maximal side effects were evaluated according to a modified WHO score for neurotoxicity, infections, skin, mucosa and myelotoxicity. Results: In 91.3% of patients contemporary positioning aids and individualized shielding techniques were used to assure a reproducible treatment. In 98 patients (73.1%) linear accelerators and in 36 patients (26.8%) {sup 60}Cobalt machines were used. Single and total dose were administered according to the protocol guidelines in more than 90% of patients. In 20.2% of patients the cribriform plate, in 1.4% the middle cranial fossa and in 21.1% the posterior fossa and in 4.5% the 2nd sacral segment were incompletely encompassed by the treatment portals. Ninety-five percent of deviations of field alignment were less than 13.0 mm (whole brain) and 12 mm (cranial spinal field) with a random error between 4.9 and 7.6 mm (whole brain) and 6.9 mm and 9.9 mm (spinal canal), respectively. In 77.5% of patients the junctions between whole brain and cranial spinal fields were placed

  12. Pharmacological treatment of the benign prostatic hyperplasia

    International Nuclear Information System (INIS)

    Benign prostatic hyperplasia is a common disease in over 50 years-old men consisting in uncontrolled and benign growth of prostatic gland that leads to lower urinary tract symptoms. The etiology of benign prostatic hyperplasia is multifactoral involving the increased conversion of testosterone in dihydrotestosterone by the prostatic 5α-reductase action, which brought about events that encourage the prostate growth (static component) and the increase of the bladder and prostate smooth muscle tone (dynamic component) regulated by the aα1 -adrenoceptors (ADR). The pharmacological treatment of the benign prostatic hyperplasia includes the prostatic 5aα-reductase inhibitors, the aα1-adrenoreceptor blockers, their combined therapy and the phytotherapy. This paper was aimed at presenting the most relevant aspects of the pharmacology of drugs used for treating the benign prostatic hyperplasia, and providing elements to analyze their efficacy, safety and tolerability. To this end, a review was made of the different drugs for the treatment of this pathology and they were grouped according to their mechanism of action. Natural products were included as lipid extracts from Serenoa repens and Pygeum africanum as well as D-004, a lipid extract from Roystonea regia fruits, with proved beneficial effects on the main etiological factors of benign prostatic hyperplasia. D-004 is a prostatic 5a-reductase inhibitor, an aα1-adrenoceptor antagonist, aα 5-lipooxygenase inhibitor and has antioxidant action, all of which reveals a multifactoral mechanism. The results achieved till now indicate that D-004 is a safe and well-tolerated product

    Hysterectomy is one of the most common gynaecological surgical procedures performed but there appears to be a decline in the performance of this procedure in Ireland in recent times. We set out to establish the extent of the decline of hysterectomy and to explore possible explanations. Data for hysterectomy for benign disease from Ireland was obtained from the Hospital In-Patient Enquiry Scheme (HIPE) section of the Economic and Social Research Institute for the years 1999 to 2006. The total number of hysterectomies performed for benign disease showed a consistent decline during this time. There was a 36% reduction in the number of abdominal hysterectomy procedures performed.

    Due to the expanding use of diagnostic imaging, an increasing number of liver tumours are discovered. Benign tumours are very common; they rarely cause symptoms and often they do not require any treatment. However, because of differences in the natural history including risk of complications and...... malignant transformation exact diagnosis is important. Dedicated radiological examinations serve as important diagnostic tools reducing the need for biopsy. In this review we provide an update on the diagnosis and treatment of benign liver tumours adding to existing recommendations on hepatocellular...

    PurposeThere have been few case reports describing cystic duct stent insertion in the management of acute cholecystitis secondary to benign disease with no case series published to date. We present our series demonstrating the role of cystic duct stents in managing benign gallbladder disease in those patients unfit for surgery.Materials and MethodsThirty three patients unfit for surgery in our institution underwent cystic duct stent insertion for the management of acute cholecystitis in the period June 2008 to June 2013. Patients underwent a mixture of transperitoneal and transhepatic gallbladder puncture. The cystic duct was cannulated with a hydrophilic guidewire which was subsequently passed through the common bile duct and into the duodenum. An 8Fr 12-cm double-pigtail stent was placed with the distal end lying within the duodenum and the proximal end within the gallbladder.ResultsTen patients presented with gallbladder perforation, 21 patients with acute cholecystitis, 1 with acute cholangitis and 1 with necrotising pancreatitis. The technical success rate was 91 %. We experienced a 13 % complication rate with 3 % mortality rate at 30 days.ConclusionCystic duct stent insertion can be successfully used to manage acute cholecystitis, gallbladder empyema or gallbladder perforations in those unfit for surgery and should be considered alongside external gallbladder drainage as a definitive mid-term treatment option.

  16. Clinical trials of CCLSG L874 and I874 protocols without cranial irradiation for standard-risk acute lymphoblastic leukemia in childhood

    International Nuclear Information System (INIS)

    In the CCLSG-874 protocol for children with low-risk (LR) and intermediate-risk (IR) acute lymphoblastic leukemia (ALL), two regimens with or without cranial irradiation (CI) were compared with respect to their ability to prevent central nervous system (CNS) leukemia and to improve overall outcome of ALL. From 1987 to 1990, 82 and 109 evaluable patients were registered into L874 and I874 protocols for LR and IR patients, respectively. All responders to induction therapy were randomized to treatment with 18 Gy of CI plus intrathecal methotrexate (MTX it) or to treatment with high-dose MTX plus MTX it. Patients were then treated with standard maintenance regimens of L874 and I874. At a median follow-up of 39 months (range 14-58 months) there was no difference in the rate of hematologic relapse between the CI group and MTX group. The rate of CNS relapse in the MTX group seemed to be higher (3 of 39 in L874 and 2 of 54 in I874) than that in the CI group (1 of 43 in L874 and 0 of 55 in I874), but these data were not statistically significant. The rates of 4-year event-free survival (EFS) in L874 were 81.1±7.6% (mean±SE) and 75.2±7.9% (ns) for the CI and MTX group, respectively, and the rates of EFS in I874 were 70.0±13.6% and 70.0±9.0% (ns) for the CI and MTX group, respectively. These data suggest that MTX alone may be as effective as CI to prolong disease-free survival in LR and IR ALL although further continuous studies are needed. Analysis of serial CCLSG protocols for ALL from 1981 revealed that the rate of EFS of ALL allover including all risk groups has gradually been increasing from 44.2±3.6% for 811 protocol and 53.1±3.5% for 841 to 65.5±3.6% for the present 874 protocol.

  17. Indoor radon and childhood leukaemia

    International Nuclear Information System (INIS)

    This paper summarises the epidemiological literature on domestic exposure to radon and risk for childhood leukaemia. The results of 12 ecological studies show a consistent pattern of higher incidence and mortality rates for childhood leukaemia in areas with higher average indoor radon concentrations. Although the results of such studies are useful to generate hypotheses, they must be interpreted with caution, as the data were aggregated and analysed for geographical areas and not for individuals. The seven available case - control studies of childhood leukaemia with measurement of radon concentrations in the residences of cases and controls gave mixed results, however, with some indication of a weak (relative risk < 2) association with acute lymphoblastic leukaemia. The epidemiological evidence to date suggests that an association between indoor exposure to radon and childhood leukaemia might exist, but is weak. More case - control studies are needed, with sufficient statistical power to detect weak associations and based on designs and methods that minimise misclassification of exposure and provide a high participation rate and low potential selection bias.

    Full Text Available Psoriasis is a common dermatosis in children with about one third of all patients having onset of disease in the first or second decade of life. A chronic disfiguring skin disease, such as psoriasis, in childhood is likely to have profound emotional and psychological effects, and hence requires special attention. Psoriasis in children has been reported to differ from that among adults being more frequently pruritic; plaque lesions are relatively thinner, softer, and less scaly; face and flexural involvement is common and guttate type is the characteristic presentation. Whether onset in childhood predicts a more severe form of psoriasis is a matter of controversy, it may cause significant morbidity particularly if it keeps relapsing. Most children have mild form of psoriasis which can be generally treated effectively with topical agents such as emollients, coal tar, corticosteroids, dithranol, calcipotriol etc. according to age and the sites affected. Narrow band UVB is the preferred form of phototherapy in children for moderate to severe disease or in patients not responding to topical therapy alone. Systemic therapies are reserved for more severe and extensive cases that cannot be controlled with topical treatment and/or phototherapy such as severe plaque type, unstable forms like erythrodermic and generalized pustular psoriasis and psoriatic arthritis. There are no controlled trials of systemic therapies in this age group, most experience being with retinoids and methotrexate with favorable results. Cyclosporine can be used as a short-term intermittent crisis management drug. There is an early promising experience with the use of biologics (etanercept and infliximab in childhood psoriasis. Systemic treatments as well as phototherapy have limited use in children due to cumulative dose effects of drugs, low acceptance, and risk of gonadal toxicity. More evidence-based data is needed about the effectiveness and long-term safety of topical

    伴中央颞部棘波良性儿童癫痫(BECTS)是最常见的原发性癫痫,也是小儿癫痫最常见的类型之一.传统观点认为BECTS患儿无认知功能的损害,但近年的研究表明患该病的儿童与健康同龄儿童相比存在更多的学习记忆等方面的问题.而脑电图是诊断该病的必不可少的辅助检查,如果从脑电图上能够发现其与认知损害之间的联系,对早用药或康复干预以提高患儿的生活质量及其回归社会有很大帮助.%Benign epilepsy of childhood with centrotemporal spikes( BECTS )is the most common idiopathic epilepsy and also the most common type of epilepsy in childhood. Traditionally, it is considered that children with BECTS have no cognitive impairment. However, some recent studies show BECTS patients have more difficulties in learning and memory compared to age-matched healthy children. Electroencephalography( EEG )is a required adjuvant diagnostic tool for BECTS. It is likely that the identification of cognitive impairment with EEG for the early intervention with medication or rehabilitation is helpful for the improvement of quality of life and reintegration to society in BECTS patients.

    BACKGROUND:The role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of acute pancreatitis has evolved over years since its introduction in 1968. Its importance in diagnosing the etiology of pancreatitis has steadily declined with the advent of less invasive diagnostic tools. The therapeutic implications of ERCP in acute pancreatitis are many fold and are directed towards management of known etiological factors or its related complications. This article highlights the current status of ERCP in acute pancreatitis. DATA SOURCES:An English literature search using PubMed database was conducted on ERCP in acute pancreatitis, the etiologies and complications of pancreatitis amenable to endotherapy and other related subjects, which were reviewed. RESULTS: ERCP serves as a primary therapeutic modality for management of biliary pancreatitis in speciifc situations, pancreatitis due to microlithiasis, speciifc types of sphincter of Oddi dysfunction, pancreas divisum, ascariasis and malignancy. In recurrent acute pancreatitis and smoldering pancreatitis it has a deifnite therapeutic utility. Complications of acute pancreatitis including pancreatic-duct disruptions or leaks, benign pancreatic-lfuid collections and pancreatic necrosis can be beneifcially dealt with. Intraductal ultrasound and pancreatoscopy during ERCP are useful in detecting pancreatic malignancy. CONCLUSIONS:The role of ERCP in acute pancreatitis is predominantly therapeutic and occasionally diagnostic. Its role in the management continues to evolve and advanced invasive procedures should be undertaken only in centers dedicated to pancreatic care.

    Background Benign prostate hyperplasia is one of the most common diseases affecting the health of the aging males. Watchful waiting is an acceptable management strategy for benign prostate hyperplasia in which the patient is monitored by the physician but receives no active intervention. The epidemiological data on this are lacking in China. Our study was designed to evaluate the changes of signs and symptoms of patients with benign prostate hyperplasia during management by watchful waiting in China.Methods One hundred and forty-five patients with benign prostate hyperplasia aged > 50 years were enrolled in management by watchful waiting. All the patients were visited every 6 months and were given an International Prostate Symptom Score and Quality of Life questionnaire to complete. They also had uroflowmetry and were assessed using ultrasonography to get the volume of prostate, transition zone and amount of residual urine. The Student's t test, the Chi-square test, and variance analysis were used in the statistical analysis.Results All patients were visited after 6 months, the mean volume of transitional zone was found to haveincreased by 1.6 ml (P<0.01), International Prostate Symptom Score was increased by 0.8 (P<0.01) and Quality of Life was increased by 0.2 (P<0.01), and there was no statistical change in other data. Among these patients,17.9% (26/145) visited again after 12 months when the data failed to show a statistically significant difference among the three groups (0, 6, and 12 months).Conclusions After one year's follow-up, the progression of benign prostate hyperplasia was slow and the clinical data did not undergo much change.

  3. Childhood obesity.

    2010-05-15

    Worldwide prevalence of childhood obesity has increased greatly during the past three decades. The increasing occurrence in children of disorders such as type 2 diabetes is believed to be a consequence of this obesity epidemic. Much progress has been made in understanding of the genetics and physiology of appetite control and from these advances, elucidation of the causes of some rare obesity syndromes. However, these rare disorders have so far taught us few lessons about prevention or reversal of obesity in most children. Calorie intake and activity recommendations need reassessment and improved quantification at a population level because of sedentary lifestyles of children nowadays. For individual treatment, currently recommended calorie prescriptions might be too conservative in view of evolving insight into the so-called energy gap. Although quality of research into both prevention and treatment has improved, high-quality multicentre trials with long-term follow-up are needed. Meanwhile, prevention and treatment approaches to increase energy expenditure and decrease intake should continue. Recent data suggest that the spiralling increase in childhood obesity prevalence might be abating; increased efforts should be made on all fronts to continue this potentially exciting trend.

    Full Text Available OBJECTIVE : To analyze studies that evaluated the role of infections as well as indirect measures of exposure to infection in the risk of childhood leukemia, particularly acute lymphoblastic leukemia. METHODS : A search in Medline, Lilacs, and SciELO scientific publication databases initially using the descriptors “childhood leukemia” and “infection” and later searching for the words “childhood leukemia” and “maternal infection or disease” or “breastfeeding” or “daycare attendance” or “vaccination” resulted in 62 publications that met the following inclusion criteria: subject aged ≤ 15 years; specific analysis of cases diagnosed with acute lymphoblastic leukemia or total leukemia; exposure assessment of mothers’ or infants’ to infections (or proxy of infection, and risk of leukemia. RESULTS : Overall, 23 studies that assessed infections in children support the hypothesis that occurrence of infection during early childhood reduces the risk of leukemia, but there are disagreements within and between studies. The evaluation of exposure to infection by indirect measures showed evidence of reduced risk of leukemia associated mainly with daycare attendance. More than 50.0% of the 16 studies that assessed maternal exposure to infection observed increased risk of leukemia associated with episodes of influenza, pneumonia, chickenpox, herpes zoster, lower genital tract infection, skin disease, sexually transmitted diseases, Epstein-Barr virus, and Helicobacter pylori . CONCLUSIONS : Although no specific infectious agent has been identified, scientific evidence suggests that exposure to infections has some effect on childhood leukemia etiology.

    AIM: To investigate the pathological characteristics and carcinogenesis mechanism of benign lymphoadenosis of oral mucosa (BLOM).METHODS: The expressions of Ki-67, CD34 and apoptosis were evaluated by immunohistochemical SP staining in 64 paraffin-embedded tissue samples. Of them, 9 were from BLOM with dysplasia, 15 from BLOM without dysplasia,15 from oral squamous cell carcinoma (OSCC), 15 from oral precancerosis, and 10 from normal tissues. Cell proliferation, apoptosis and angiogenesis of tissue samples were also analyzed.RESULTS: The expression of Ki-67 in BLOM with dysplasia,oral precancerosis and OSCC was significantly higher than in BLOM without dysplasia and normal mucosa. The microvascular density (MVD) in BLOM with and without dysplasia, oral precancerosis, and OSCC was significantly higher than in normal mucosa. Apoptosis in BLOM and oral precancerosis was significantly higher than in OSCC and normal mucosa.CONCLUSION: Benign lymphoadenosis of oral mucosa has potentialities of cancerization.

  13. Skeletal scintigraphy in benign and malignant disease

    International Nuclear Information System (INIS)

    This paper begins with a discussion of the technical factors in skeletal scintigraphy, including collimation, the use of three-phase bone scan, and single-photon emission computed tomography. Skeletal scintigraphy for benign conditions is commonly indicated for the patient presenting with pain (trauma, sports-related injury, posttraumatic pain syndrome, painful orthopedic prosthesis) and for the patient with abnormal laboratory test results (metabolic bone disease, Paget disease). For malignant conditions, the bone scan is useful in the evaluation of metastases in patients with extraosseous malignancies and primary bone tumors. The discussion addresses the various scan patterns seen in the more common tumors, such as prostate carcinoma, breast carcinoma, and lung carcinoma. Bone scintigraphy is an exquisitely sensitive modality. With some understanding of the techniques necessary for obtaining the optimal bone scan, and of the patterns that can be seen in various clinical conditions, the radiologist will find the bone scan a very specific tool for evaluating both benign and malignant diseases

MATERIALS AND METHODS: ILP was performed in 16 patients with normal thyroid function and a solid...... benign thyroid nodule. None of the patients had uptake on a radionuclide scan. Patients underwent one ILP session. A needle was positioned in the thyroid nodule with US guidance, and the laser fiber was placed in the lumen of the needle. Patients were treated for 287-1,200 seconds with an output power of...... 1-3 W. ILP was performed with continuous US guidance and terminated when the echogenic changes were stationary. Thyroid nodule volume and thyroid function were evaluated before and 1, 3, and 6 months after treatment. During the same period, 15 untreated patients (control group) were followed up to...

  16. Radiotherapy in benign uterine bleeding disorders

    International Nuclear Information System (INIS)

    Radiotherapy was earlier a method of choice for treatment of benign bleeding disorders (metropathia), especially in woman of high surgical risk. During the period 1912 to 1977 933 women with benign bleeding disorders were treated at Radiumhemmet with intracavitary brachytherapy or external irradiation or a combination of both. The result with regard to cure of the uterine bleedings was good (48%). Hormonal withdrawal symptoms after treatment were noted in 45% of the patients. In the long term follow up an increased risk of cardiovascular death was found in women treated before menopause. Malignant tumours occurred in 107 cases versus 90.2 expected. The estimated ovarian dose of ionizing radiation varied from 3.5 Gy to 6.0 Gy for the three standard techniques. Two women gave birth to a healthy child 4 and 5 years after intracavitary radium treatment. The estimated absorbed dose to the ovaries in these two women were 1 Gy and 4 Gy, respectively

    Benign biliary strictures are being increasingly treated with endoscopic techniques. The benign nature of the stricture should be first confirmed in order to ensure appropriate therapy. Surgery has been the traditional treatment, but there is increasing desire for minimally invasive endoscopic therapy. At present, endoscopy has become the first line approach for the therapy of postliver transplant anastomotic strictures and distal (Bismuth Ⅰ and Ⅱ) post-operative strictures. Strictures related to chronic pancreatitis have proven more difficult to treat,and endoscopic therapy is reserved for patients who are not surgical candidates. The preferred endoscopic approach is aggressive treatment with gradual dilation of the stricture and insertion of multiple plastic stents. The use of uncovered self expandable metal stents should be discouraged due to poor long-term results. Treatment with covered metal stents or bioabsorbable stents warrants further evaluation. This area of therapeutic endoscopy provides an ongoing opportunity for fresh research and innovation.

  18. Case report: Benign porta hepatic schwannoma

    International Nuclear Information System (INIS)

    Schwannoma is a myelin sheath tumor that can occur almost anywhere in the body. The most common locations are the central nervous system, extremities, neck, mediastinum and retroperitoneum. Benign schwannomas in the porta hepatis are extremely rare and radiologically are diagnosed as either enlarged lymph nodes or bowel masses, such as gastrointestinal stromal tumors. In this location they usually produce symptoms by compressing adjacent structures and often present with obstructive jaundice. The preoperative diagnosis can be extremely difficult

    Benign intracranial hypertension (BIH) (also known as pseudotumor cerebri and empty sella syndrome) remains a diagnostic challenge to most physicians. The modified Dandy criteria consist of, the classic findings of headache, pulsatile tinnitus, papilledema, and elevated cerebrospinal fluid (CSF) pressure, however, these are rarely collectively present in any one patient. Furthermore, these findings can wax and wane over time. Due to the nature of this disease, both signs and symptoms may be i...

    Purpose: To evaluate long-term results of treatment of benign bile duct strictures. Materials and methods: From February 1994 to November 2005, 21 patients (9 men, 12 women) with median age of 50.6 years (range 27-77 years) were indicated to percutaneous treatment of benign bile duct stricture. Stricture of hepatic ducts junction resulting from thermic injury during laparoscopic cholecystectomy was indication for treatment in one patient, stricture of hepaticojejunostomy was indication for treatment in all other patients. Clinical symptoms (obstructive jaundice, anicteric cholestasis, cholangitis or biliary cirrhosis) have appeared from 3 months to 12 years after surgery. Results: Initial internal/external biliary drainage was successful in 20 patients out of 21. These 20 patients after successful initial drainage were treated by balloon dilatation and long-term internal/external drainage. Sixteen patients were symptoms free during the follow-up. The relapse of clinical symptoms has appeared in four patients 9, 12, 14 and 24 months after treatment. One year primary clinical success rate of treatment for benign bile duct stricture was 94%. Additional two patients are symptoms free after redilatation (15 and 45 months). One patient is still in treatment, one patient died during secondary treatment period without interrelation with biliary intervention. The secondary clinical success rate is 100%. Conclusion: Benign bile duct strictures of hepatic ducts junction or biliary-enteric anastomosis are difficult to treat surgically and endoscopically inaccessible. Percutaneous treatment by balloon dilatation and long-term internal/external drainage is feasible in the majority of these patients. It is minimally invasive, safe and effective.

    Pseudoepitheliomatous hyperplasia is an extremely rare condition presenting as a lesion on the glans penis in older men. Physical exam without biopsy cannot differentiate malignant from nonmalignant growth. We report a case of large penile mass in an elderly male with a history of lichen sclerosis, highly suspicious for malignancy. Subsequent surgical removal and biopsy demonstrated pseudoepitheliomatous hyperplasia, an unusual benign histopathologic diagnosis with unclear prognosis. We review the literature and discuss options for treatment and surveillance. PMID:26793536

  3. Surgical therapy of benign pineal tumors

    International Nuclear Information System (INIS)

    Currently, there is no way that the author knows to satisfactorily distinguish the benign lesions from their malignant cousins without a shadow of doubt. This includes preoperative evaluation of the clinical history, biological markers in serum and CSF, CT scans with and without contrast in various projections including the horizontal, coronal and sagittal cuts, and arteriography. Because the author has personally encountered difficulty in precisely diagnosing these tumors at routine light microscopy, especially when fragments are small, he has a personal aversion to the technique of diagnosis which enlists the use of a stereotactically placed biopsy needle. The author feels that virtually all of the pineal tumors require surgical exposure and sufficient tissue removal to ensure an accurate histological diagnosis. With experience, the author believes the surgeon can tell as he exposes the posterior and lateral aspects of these tumors whether or not they are encapsulated and therefore potentially resectable. This anatomical variation may be identified prior to operative intervention by an arteriogram especially with injection of large quantities of dye into the carotid system. With the advent of the CUSA (Cavitron Lasersonics, Cooper Medical Device Corporation, Stamford, CT), the author has used this instrument with increased facility and benefit in the removal of benign relatively avascular tumors of the pineal region. This instrument is ideal in coring out the interior of the tumor while creating little displacement of the tumor capsule. Some of the benign tumors, especially the meningiomas may be partially or heavily calcified and this instrument exhibits particular usefulness in these cases

    The manufacturing of silicon devices--from polysilicon production, crystal growth, ingot slicing, wafer cleaning, device processing, to encapsulation--requires many steps that are energy intensive and use large amounts of water and toxic chemicals. In the past two years, the silicon integrated-circuit (IC) industry has initiated several programs to promote environmentally benign manufacturing, i.e., manufacturing practices that recover, recycle, and reuse materials resources with a minimal consumption of energy. Crystalline-silicon solar photovoltaic (PV) modules, which accounted for 87% of the worldwide module shipments in 1997, are large-area devices with many manufacturing steps similar to those used in the IC industry. Obviously, there are significant opportunities for the PV industry to implement more environmentally benign manufacturing approaches. Such approaches often have the potential for significant cost reduction by reducing energy use and/or the purchase volume of new chemicals and by cutting the amount of used chemicals that must be discarded. This paper will review recent accomplishments of the IC industry initiatives and discuss new processes for environmentally benign silicon solar-cell manufacturing.

  5. Benign versus malignant vertebral compression fractures: distinction with T1-weighted, fast spin-echo T2-weighted, and fat-suppressed gadolinium-enhanced T1-weighted images

    International Nuclear Information System (INIS)

    To differentiate malignant vertebral compression fractures from benign fractures, as seen on spin-echo T1-wieghted, fast spin-echo T2-weighted, and fat-suppressed gadolinium-enhanced T1-weighted MR images. Thirty two benign (18 acute and 14 chronic) and 28 malignant vertebral collapses were studied in 54 patients aged between 15 and 78 (mean, 51) years. Malignant compression fractures involved only metastasis. We obtained sagittal and axial fast spin-echo T2-weighted images, and unenhanced and fat-suppressed gadolinium-enhanced T1-weighted images, and analyzed MR signal intensity, enhancement patterns, and morphologic changes including convex posterior cortex vs retropulsion of a bone fragment, focal vs diffuse paraspinal mass, and epidural mass. All cases of acute benign and malignant compression fractures showed low signal intensity within the vertebral body on T1-weighted images, and substantial contrast enhancement on fat-suppressed gadolinium-enhanced T1-weighted images. Acute benign and malignant compression fractures were distinguished on the basis of three signal intensity characteristics : hypointense band (acute benign cases 77% ; malignant cases 0%), diffuse low signal intensity(17% vs 86%) and involvement of pedicle (0% vs 75%). Fast spin-echo T2-weighted images played little role in distinguishing between the two. Three morphologic changes were suggestive of malignancy : convex posterior cortex (malignant cases 75% ; benign 0%), epidural mass (79% vs 5%), and focal paraspinal mass (57% vs 0%). Retropulsion of a bone fragment (benign cases 63% ; malignant cases 14%) was preferable for benignancy. In addition, thin diffuse paraspinal mass (benign cases 15% ; malignant cases 14%) was seen. The morphologic and signal intensity characteristics seen on T1-weighted images were useful for distinguishing benign and malignant vertebral compression fractures. Fast spin-echo T2-weighted and fat-suppressed gadolinium-enhanced T1-weighted images played little role

    Medulloblastoma accounts for 15-20% of childhood nervous system tumours. The risk of dying was reduced by 30% in the last twenty years. Patients are divided in risk strata according to post-surgical disease, dissemination, histology and some molecular features such as WNT subgroup and MYC status. Sixty to 70% of patients older than 3 years are assigned to the average-risk group. High-risk patients include those with disseminated and/or residual disease, large cell and/or anaplastic histotypes, MYC genes amplification. Current and currently planned clinical trials will: (1) evaluate the feasibility of reducing both the dose of craniospinal irradiation and the volume of the posterior fossa radiotherapy (RT) for those patients at low biologic risk, commonly identified as those having a medulloblastoma of the WNT subgroup; (2) determine whether intensification of chemotherapy (CT) or irradiation can improve outcome in patients with high-risk disease; (3) find target therapies allowing tailored therapies especially for relapsing patients and those with higher biological risk.

    The purpose of this study was to review unilateral acute maculopathy associated with hand-foot-mouth disease with a representative case. Clinical course of a 24-year-old male case with unilateral acute idiopatic maculopathy documented by multimodal imaging is presented, and a review of similar cases is given. On initial examination, best-corrected visual acuity was 20/200 in the left eye. Fundoscopy revealed grayish-yellowish subretinal exudate, and fluorescein angiography demonstrated irregular mottled hyperfluorescence at the central macula. Spectral domain optical coherence tomography demonstrated disruption of ellipsoid layer, which partially resolved on follow-up examinations. Best-corrected visual acuity increased to 20/20 at 3 months, with persistent retinal changes, and mild disruption of ellipsoid layer and persistent mild metamorphopsia. Although hand-foot-mouth disease is usually benign and self-limited in childhood, it may be rarely associated with unilateral vision loss due to maculopathy, especially at early adulthood in both sexes. Vision loss associated with this eruption is acute and reversible in most cases, despite some residual pigmentary and scarring changes in all cases and persistent mild visual loss in some cases. Exact pathophysiology, the causes of variability of clinical features, adulthood onset, unilateral involvement, and role of multimodal imaging are issues which need to be clarified with further research.

    International Nuclear Information System (INIS)

    Radiation therapy of benign diseases represent a wide panel of indications. Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren's disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

    Earlier this year, tamsulosin, an alpha blocker previously only available on prescription, became available for sale by pharmacists as a treatment for functional symptoms of benign prostatic hyperplasia (BPH) in men aged 45-75 years (Flomax Relief MR - Boehringer Ingelheim). A television advert for the over-the-counter (OTC) product claims that it is a "simple and effective" treatment that can relieve symptoms within 1 week, allowing the user to "take control of your annoying pee problems".¹ Here we review the evidence on tamsulosin and assess whether its availability as an OTC product confers worthwhile advantages.

    2008-02-01

    Two groups of drugs, alpha blockers and 5-alpha-reductase inhibitors (5ARI), are currently widely used for the medical treatment of benign prostatic syndrome (BPS). Alpha blockers are characterized by a rapid onset of efficacy. If given at an adequate dose, all alpha blockers have a similar efficacy, yet quantitative differences regarding side effects exist. The onset of clinical efficacy of 5ARIs is delayed and dependent on prostate volume. Symptom improvement is generally less pronounced than with alpha blockers, yet this difference declines with time. 5ARI, in contrast to alpha blockers, reduce prostate volume and the risk of long-term BPS complications such as prostate surgery or acute urinary retention. The combination therapy of alpha blockers and 5ARI is superior to either monotherapy; however, this superiority becomes evident only after prolonged (>1 year) therapy. Because of additive side effects, this combination should be reserved for BPS patients with a high risk of progression. Regarding plant extracts, no definitive recommendation can be given because of a limited number of high-quality clinical trials. The use of antimuscarinics in men with BPS with a dominance of storage symptoms and without significant obstruction is promising, although further trials, particularly with a longer study duration, are required.

    Full Text Available Cases of benign infantile convulsions with mild gastroenteritis (BICE treated in our hospital from 2008 to 2012 were analyzed retrospectively. Among the 65 cases of convulsions with acute diarrhea, there were 18 cases of BICE, 15 cases of febrile seizures, 13 cases of epilepsy, 6 cases of viral encephalitis, 6 cases of hyponatremia encephalopathy, 3 cases of hypernatremia encephalopathy, 2 cases of toxic encephalopathy, and 2 cases of hypocalcemia convulsion. The convulsion occurred mostly during the first 2 d of the illness and was in a generalized tonic or tonic-clonic form. Positive rotavirus antigens in the BICE patients were detected in 83.33% (15/18. Phenobarbital was administered after the first convulsion (5-10 mg/kg, and diazepam was given intravenously in case of recurrence (0.10-0.30 mg/kg. BICE occurs frequently in infantile and controlling relapse is the main purpose. The prognosis is good. doi: 10.3969/j.issn.1672-6731.2014.03.019

    Materials and Methods: In this retrospective study, percutaneous biliary interventions were performed in fifteen children with a mean age of 10.2 years (range 14 days-14 years. Patients presented with jaundice (n=5 and/or cholangitis (n=10. Percutaneous transhepatic biliary drainage (PTBD performed in 10 patients, PTBD plus balloon dilation in 3, percutaneous cholecystostomy (PC in 1, PTBD following PC in 1. Results: All procedures were technically successful. No procedure-related mortality occurred in patients. Serum bilirubin levels returned to normal or near normal in ten of twelve cases. Preexisting cholangitis and acute cholecystitis resolved in all patients. Six patients underwent surgery following percutaneous management. Nine patients cured primarily with percutaneous interventions with no further treatment. Conclusion: Percutaneous biliary interventions can be performed effectively in benign diseases of children. It can be performed either as a primary treatment modality or as a bridge prior to surgery. In most of cases, percutaneous treatment is sufficient and unnecessary surgery is prevented.

  8. An evaluation of the relationship between the quality of prophylactic cranial radiotherapy in childhood acute leukemia and institutional experience: a Quality Assurance Review Center-Pediatric Oncology Group study

    International Nuclear Information System (INIS)

    Purpose: The Pediatric Oncology Group Protocol 9404 was a prospective clinical trial of two forms of chemotherapy in childhood T-cell acute lymphoblastic leukemia and advanced stage T-cell lymphoblastic non-Hodgkin's lymphoma. The protocol called for prophylactic C1 whole brain external beam irradiation, 18 Gy in 2 Gy/fraction for 9 fractions. We hypothesized that a correlation would be found between the number of children irradiated on protocol by an institution and the compliance rate of that institution with radiotherapy quality assurance (QA) guidelines. We also hypothesized that QA compliance would improve as the study progressed. Methods and Materials: We scored the radiation dose as a minor deviation from protocol guidelines if the dose to the prescription point differed from the protocol by 6-10%, and a major deviation if it differed from protocol by >10%. Treatment volumes were scored as a minor deviation if the margins were less than specified or the fields were excessively large. A major deviation was defined as the transection of a potential leukemia-bearing volume such as would be caused by blocking the cribriform plate, optic nerve, or temporal lobe. When the treating physician submitted a treatment plan and simulator film at the initiation of therapy to the Quality Assurance Review Center (QARC), a rapid turn-around review of the plan and suggestions for improvement was provided. At the end of therapy, all simulator and port films were reviewed at the QARC. Results: We reviewed the data from 353 patients treated at 73 institutions in the United States, Canada, and Europe. Of these patients, 2% (n=7) were not assessable for QA because of incomplete information. Minor quality deviations were found in 27.7% of patients (n=98) and major deviations in 7.9% (n=28). The frequency of major deviations for institutions placing 1-4 patients on study was 11% vs. 5.5% for institutions placing ≥5 patients (p5 patients (p not significant). The frequency of major

  9. Causes of childhood leukaemia and lymphoma

    International Nuclear Information System (INIS)

    Childhood cancer is rare comprising less than 1% of all malignancies diagnosed each year in developed countries. Leukaemia is the commonest form of cancer in children accounting for around a third of all childhood cancer, with acute lymphoblastic leukaemia (ALL) being the most prevalent. Biologically specific subtypes of ALL and acute myeloblastic leukaemia (AML), the other major morphological type of childhood leukaemia, are characterised by chromosomal changes. Whilst over 200 genes have been associated with chromosomal translocations, to date, only MLL, TEL, and AML1 have been linked with childhood leukaemia. Interestingly, there is increasing evidence to support the theory that gene rearrangements such as these may originate in utero. As with many other human diseases, both genetic and environmental factors have been implicated in the aetiology of the disease. Although much has been documented with regard to diet, smoking, alcohol consumption and recreational and prescription drug use during pregnancy, there is no consistent evidence to support a link with any of these factors and childhood leukaemia. However, findings from studies investigating prenatal and early life exposures are often based on small numbers of cases as both the type of cancer and exposure are rare. Furthermore, accurate information relating to past exposures can be difficult to obtain and is often reliant on self-reporting. To further our understanding of the aetiology of childhood leukaemia and lymphoma, there are areas which clearly warrant investigation. These include collection of parental dietary folate data combined with genetic analysis of the folate related genes, in utero exposure to DNA topoisomerase II inhibitors, and the possible effects of assisted reproduction technology on disease susceptibility

    With current childhood acute lymphoblastic leukemia (ALL) treatment protocols the cure rate approaches 90%. In the 10 percent of case fatalities, 2 major challenges stand out: incurable relapses of ALL and (infectious) deaths-in-remission. Thus, reducing toxicity is becoming an important goal to further improve childhood ALL survival. The Dutch Childhood Oncology Group (DCOG) ALL 10 protocol was designed to investigate whether a reduction of chemotherapeutic treatment intensity after a standa...

    Benign paroxysmal positional vertigo is one of the most common types of vertigo caused by peripheral vestibular dysfunction. Although head trauma, migraine, long-term bed rest, Ménière disease, viral labyrinthitis, and upper respiratory tract infections are believed to be predisposing factors, most cases of benign paroxysmal positional vertigo are idiopathic. Ear surgery is another cause, but after non-otologic surgery, attacks of benign paroxysmal positional vertigo are rare. We describe thr...

  18. The role of combination medical therapy in benign prostatic hyperplasia.

    To review key trials of monotherapy and combination therapy of alpha(1)-adrenergic receptor antagonists (alpha(1)-ARAs), 5alpha-reductase inhibitors (5alphaRIs) and anti-muscarinic agents in the treatment of lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). To assess the safety and efficacy of combination therapies for LUTS associated with BPH, a search of the MEDLINE and Cochrane databases (1976-2008) was conducted for relevant trials and reviews using the terms benign prostatic hyperplasia, lower urinary tract symptoms, alpha(1)-adrenergic receptor antagonists, 5alpha-reductase inhibitors, anti-muscarinics, anticholinergics, combination therapy, alfuzosin, doxazosin, tamsulosin, terazosin, dutasteride, finasteride, tolterodine, flavoxate, propiverine, oxybutynin, erectile dysfunction, sildenafil, vardenafil and tadalafil. Data from the Medical Therapy of Prostatic Symptoms (MTOPS) study indicated a role for long-term use of alpha(1)-ARAs and 5alphaRIs in combination. In the MTOPS study, combination therapy with the alpha(1)-ARA doxazosin and the 5alphaRI finasteride was significantly more effective than either component alone in reducing symptoms (P=0.006 vs doxazosin monotherapy; Pfinasteride monotherapy) and in lowering the rate of clinical progression (Pdutasteride resulted in a significantly greater decrease in International Prostate Symptom Score (IPSS) when compared with either monotherapy. Several recent trials have studied the efficacy of combining alpha(1)-ARAs and anti-muscarinic agents in the treatment of BPH. These studies have found this combination to result in statistically significant benefits in quality of life scores, patient satisfaction, urinary frequency, storage symptoms and IPSS scores. Studies have not shown an increased risk of urinary retention associated with the use of anti-muscarinics in a highly select cohort of men with BPH. The available data suggest that combination therapy can be beneficial

    Pain and focal masses in the foot and ankle are frequently encountered and often initiate a workup including imaging. It is important to differentiate benign lesions from aggressive benign or malignant lesions. In this review, multiple examples of osseous and soft tissue tumors of the foot and ankle will be presented. Additionally, the compartmental anatomy of the foot and ankle will be discussed in terms of its relevance for percutaneous biopsy planning and eventual surgery. Finally, a general overview of the surgical management of benign, benign aggressive and malignant tumors of the foot and ankle will be discussed. (orig.)
