    Through a comprehensive review of the current literature, the present article investigates several aspects of low grade astrocytomas (LGA), including prognostic factors, treatment strategies and follow-up regimes. LGA are in general relatively slow-growing primary brain tumours, but they have...... as the course of disease. The current literature seems to support the idea that treatment with radical tumour resection, where possible, yields better long term outcome for patients with LGA. However, adjuvant therapy is often necessary.

    Parental occupations were investigated as possible risk factors for astrocytoma, the most frequently occurring brain tumor in children. A case-control study of 163 pairs was performed. Cases under 15 years of age at diagnosis in 1980-1986 were identified through the tumor registries of eight hospitals in Pennsylvania, New Jersey, and Delaware. Controls were selected by random-digit dialing and were matched to cases on age, race, and telephone area code. Occupations before the child's conception, during the pregnancy, and after the child's birth were studied separately. We did not observe any strong associations. Significantly more fathers of cases were electrical or electronic repairmen, a subgroup of an occupational category previously associated with increased risk. An excess of case mothers employed as nurses was observed, which was significant for mothers of children diagnosed before 5 years of age. Elevated although not significant odds ratios were observed for some white collar and professional occupations in case parents; for paternal exposure to paint and paternal occupation in the paper and pulp mill industry, both in the period after the child's birth; and for maternal occupation as a hairdresser. The lack of strong associations may have resulted from low statistical power for some job groupings. Our study, unlike previous studies, focused on a single type of brain tumor: childhood astrocytoma. Thus our results suggest that some parental occupations associated with childhood brain tumors in previous studies may not be risk factors for childhood astrocytoma.

    Gestational and familial risk factors were investigated for their association with astrocytoma, the most frequently occurring brain tumor in children. A case-control study of 163 matched pairs was performed. Cases under 15 years of age at diagnosis in 1980-1986 were identified through the tumor registries of 8 hospitals in Pennsylvania, New Jersey, and Delaware. Controls were selected by random digit dialing and were matched to cases for age, race, and telephone area code and exchange. Maternal antinausea medications increased the risk of childhood astrocytoma [OR (odds ratio) = 2.0, P = 0.04]. Cured meat consumption during pregnancy was more common among cases (OR = 1.9, P = 0.07), and a significant trend with increasing frequency of consumption was observed (P = 0.04). Results for gestational exposure to marijuana (OR = 2.8, P = 0.07) were of borderline significance. Gestational exposure to neurally active medications, alcohol, and tobacco were not risk factors. There was a significant trend for cases to be of higher birth weight (P = 0.03). Mental retardation (OR = 3.0, P = 0.04) and cancer (OR = 1.7, P = 0.02) in a relative of the child significantly increased the risk of astrocytoma. Significantly increased risks were observed for brain tumors in relatives of children 0-4 years of age at diagnosis (OR = 6/0, P = 0.04). A significant protective effect was observed for maternal history of miscarriage or stillbirth (OR = 0.5, P = 0.01). The results of this study suggest that some gestational and familial factors may increase the risk of childhood astrocytoma.

    The aims of the studies included in this thesis were: - to investigate the reliability of {sup 201}Thallium single photon emission computed tomography. Tl SPECT for preoperative diagnosis and histological staging of malignant astrocytomas in comparison with CT; - to develop a method for quantification of cerebral thallium uptake, and to evaluate the quantitative measurement in comparison with CT, for astrocytoma treatment follow-up purposes; - to compare quantitative Tl SPECT and proton magnetic resonance spectroscopy (H-MRS) with conventional MR imagingfor astrocytoma monitoring, and to evaluate associations between change of morphological tumour characteristics during treatment and changes of cerebral thallium uptake and metabolic ratios. Results and conclusions: - High TI-index, calculated as a ratio comparing tumour uptake to uptake in the contralateral hemisphere, is an indicator of highly malignant astrocytoma. Differentiation between the high-grade astrocytomas, the low-grade astrocytomas, and infectious lesions is only partial, with an overlap of Tl-indexes between these groups. High-grade astrocytomas that do not show contrast enhancement on CT, and astrocytomas with central necrosis and moderate ring-enhancement, tend to be underestimated when evaluated by Tl-index calculation. Tl SPECT is not a reliable method for non-invasive tumour staging among the group of highly malignant astrocytomas. - Quantification of cerebral TI-uptake, defining the volume of viable tumour tissue, is a new method for astrocytoma chemotherapy monitoring. Results suggest that the method provides prognostic information, and information of treatment efficacy, at an earlier stage than CT. - We did not find a higher accuracy of quantitative Tl SPECT than of MR for monitoring purposes and our results indicated that treatment induced MR changes were interrelated with TI-uptake variations. - Multi-voxel H-MRS was difficult to apply for astrocytoma treatment monitoring, due to the

    Full Text Available Background. The aim of this study was to analyze the outcome after the surgical treatment of patients with malignant brain astrocytomas, as well as the factors influencing the outcome. Retrospective study was performed on 145 operated patients (102 with glioblastoma multiforme, and 43 with anaplastic astrocytomas. Methods. Clinical state was graded according to the Yasargil scale (grades I-IV and the Karnofski score, and the outcome was defined either as good (better or unchanged clinical state or as poor (deteriorated state or death. The outcome was correlated with patients’ age and preoperative clinical condition, as well as with the localization extensiveness and the extent of resection of the tumor. Results. Preoperative clinical state of patients most frequently corresponded to grades II-III (75.9%. Radical resection was done in 48.3%, subtotal in 15.2%, partial in 30.3%, and biopsy was performed in 6.2% of patients, with the total operative mortality of 16.5%, morbidity of 9.7%, and good postoperative outcome in 73.8% of the patients. The incidence of good postoperative outcome did not significantly depend on the tumor location (42.6-78.3%, cortical presentation, the extent of resection (68.2-75.7% and preoperative clinical state (67.8-81.5%. Good outcome was seen in 82.7% of patients with one, and in 53.8% of patients with three or more infiltrated lobes (p<0.01. Patients with poor outcome were significantly older in average than the patients with good outcome (58.9±12.1 and 50.9±13.4 years of age, respectively; p<0.05. Operative mortality was 7.4% and 27.3% for clinical grades II and IV (p<0.05, namely 11% and 23.8% for the patients with the Karnofski score above and under 50 (p<0.05 respectively. Conclusion. The outcome after the operative treatment of malignant cerebral astrocytomas significantly depended on patient’s age and the extensity of the tumor. For such patients operative mortality was also significantly influenced by

    This study was designed to investigate whether the Notch pathway is involved in the development of diffuse spinal cord astrocytomas. BALB/c nude mice received injections of CD133(+) and CD133(-) cell suspensions prepared using human recurrent diffuse spinal cord astrocytoma tissue through administration into the right parietal lobe. After 7-11 weeks, magnetic resonance imaging was performed weekly. Xenografts were observed on the surfaces of the brains of mice receiving the CD133(+) cell suspension, and Notch-immunopositive expression was observed in the xenografts. By contrast, no xenografts appeared in the identical position on the surfaces of the brains of mice receiving the CD133(-) cell suspension, and Notch-immunopositive expression was hardly detected either. Hematoxylin-eosin staining and immunohistochemical staining revealed xenografts on the convex surfaces of the brains of mice that underwent CD133(+) astrocytoma transplantation. Some sporadic astroglioma cells showed pseudopodium-like structures, which extended into the cerebral white matter. However, it should be emphasized that the subcortex xenograft with Notch-immunopositive expression was found in the fourth mouse received injection of CD133(-) astrocytoma cells. However, these findings suggest that the Notch pathway plays an important role in the formation of astrocytomas, and can be considered a novel treatment target for diffuse spinal cord astrocytoma.

    Subependymal giant cell astrocytomas are benign tumors often observed with tuberous sclerosis complex. These tumors are rarely diagnosed during fetal life or early infancy. Until recently, the only available treatment has been surgical resection. Current clinical research has demonstrated that everolimus can induce these tumors' regression. We report a 19-month-old boy with tuberous sclerosis complex. At 2 months of age, he presented with congenital subependymal giant cell astrocytoma that was complicated by refractory epilepsy and severe mental retardation. Treatment with everolimus was started when he was 10 months old. Three months after initiating everolimus, the tumor was significantly reduced in size, and the reduction was subsequently maintained. His seizures decreased and he showed cognitive and developmental improvement. No severe adverse events have been observed to date. Everolimus has promise as an effective alternative to surgery for subependymal giant cell astrocytomas during early infancy.

    2015-03-01

    Full Text Available Background Pilocytic astrocytoma (PA is a low-grade glioma that occurs mainly in children and young adults. The histomorphology of PA located in the cerebellum (WHOⅠ is very typical. This article is to report one case of PA in the cerebellum of an 8-year-old child, and to discuss the clinical, imaging and pathological features of PA and clinicopathological differentiations from relevant tumors.  Methods and Results An 8-year-old girl presented intermittent headache for one month and the headache was aggravated for 7 d. MRI showed circular space-occupying lesion in the left cerebellar hemisphere and cerebellar vermis, and the lesion revealed uneven signals. During the surgery, the tumor was soft and jellylike, with poor blood supply. Histologically, tumor cell nuclei were round or oval; cytoplasmic projections on both ends were slender hair-like, and were arranged around the blood vessels. Part of tumor cells had spindle nuclei, and showed fascicular compact arrangement or loose reticular arrangement. The pathomorphism of this tumro was slightly different from that of typical PA. It had unusually rich blood vessels, and Rosenthal fibers and eosinophilic granules were not obvious. Tumor cells were diffusely positive for glial fibrillary acidic protein (GFAP, synaptophysin (Syn, vimentin (Vim and P53, but negative for cytokeratin (CK, neuronal nuclei (NeuN and neurofilament protein (NF. Ki-67 index was 2%-5%. Vascular endothelial cells were positive for CD34, and scatteredly expressed CD68. Pathological diagosis was pilocytic astrocytoma (WHOⅠ.  Conclusions Pilocytic astrocytoma usually happens in children and adolescents and often occurs in the cerebellum. Rosenthal fibers and eosinophilic granules are helpful to make a clear diagnosis, but they are not necessary conditions of diagnosis. Differential diagnoses should be paid attention, such as pilomyxoid astrocytoma, angiocentric glioma and dysembryoplastic neuroepithelial tumor (DNT

    Study Design Retrospective study. Purpose To obtain information useful in establishing treatment guidelines by evaluating baseline clinical features and treatment outcomes of patients with spinal cord astrocytoma (SCA). Overview of Literature The optimal management of SCA remains controversial, and there are no standard guidelines. Methods The study included 20 patients with low-grade and 13 with high-grade SCA surgically treated between 1989 and 2014. Patients were classified according to the extent of surgical resection. Survival was assessed using Kaplan–Meier plots and compared between groups by log-rank tests. Neurological status was defined by the modified McCormick scale and compared between groups by Mann–Whitney U tests. Results Surgical resection was performed for 19 of 20 low-grade (95%) and 10 of 13 high-grade (76.9%) SCA patients. Only nine patients (27.3%) underwent gross total resection, all of whom had low-grade SCA. Of all patients, 51.5% showed deteriorated neurological status compared to preoperative baseline. Median overall survival was significantly longer for low-grade SCA than that (91 months, 78% at 5 years vs. 15 months, 31% at 5 years; p=0.007). Low-grade SCA patients benefited from more aggressive resection, whereas high-grade SCA patients did not. Multivariate analysis revealed histology status (hazard ratio [HR], 0.30; 95% confidence interval [CI], 0.09–0.98; p<0.05) and postoperative neurological status (HR, 0.12; CI, 0.02–0.95; p<0.05) as independent predictors of longer overall survival. Adjuvant radiotherapy had no significant impact on survival rate. However, a trend for increased survival was observed with radiation cordotomy (RCT) in high-grade SCA patients. Conclusions Aggressive resection for low-grade and RCT may prolong survival. Preservation of neurological status is an important treatment goal. Given the low incidence of SCA, establishing strong collaborative, interdisciplinary, and multi-institutional study groups

    This review discusses available laboratory and clinical data as well as recent advances in our knowledge about prognostic factors and their implications for the design of future clinical trials. Results: Elucidation of the biology of malignant astrocytomas allowed for development of rational new approaches, such as gene therapy and immunotherapy, which could interfere with established treatment regimens or being used independently. Possible strategies include the restoration of defective cancer-inhibitory genes, cell transduction or transfection with antisense DNA corresponding to genes coding for growth factors and their receptors, or with the so-called suicide genes. Several antiangiogenic approaches such as administration of thalidomide, protamine, or monoclonal antibodies against vascular endothelial growth factor have been developed, too. Further treatment possibilities include modulation of drug resistance, e.g. by P-glycoprotein antagonists or O6-alkyl-guanine-DNA-transferase inhibitors, inhibition of matrix metalloproteinases, inhibition of protein kinase C, and administration of agents such as phenylbutyrate or valproic acid that showed promising antiproliferative effects in vitro. Conclusions: Several rational new approaches are now entering clinical trials. In the light of limited survival after standard treatment it is recommended that patients should be offered participation in such trials. (orig.)

    1988-04-01

    Brain tumors are the second most common childhood malignancy. Between 1975 and 1985, 462 newly diagnosed patients were treated at the Children's Hospital of Philadelphia; 207 (45%) tumors arose in the posterior fossa and 255 (55%) appeared supratentorially. A wide variety of histological subtypes were seen, each requiring tumor-specific treatment approaches. These included primitive neuroectodermal tumor (n = 86, 19%), astrocytoma (n = 135, 30%), brainstem glioma (n = 47, 10%), anaplastic astrocytoma (n = 32, 7%), and ependymoma (n = 30, 6%). Because of advances in diagnostic abilities, surgery, radiotherapy, and chemotherapy, between 60% and 70% of these patients are alive today. Diagnostic tools such as computed tomography and magnetic resonance imaging allow for better perioperative management and follow-up, while the operating microscope, CO/sub 2/ laser, cavitron ultrasonic aspirator and neurosurgical microinstrumentation allow for more extensive and safer surgery. Disease specific treatment protocols, utilizing radiotherapy and adjuvant chemotherapy, have made survival common in tumors such as medulloblastoma. As survival rates increase, cognitive, endocrinologic and psychologic sequelae become increasingly important. The optimal management of children with brain tumors demands a multidisciplinary approach, best facilitated by a neuro-oncology team composed of multiple subspecialists. This article addresses incidence, classification and histology, clinical presentation, diagnosis, pre-, intra- and postoperative management, long-term effects and the team approach in posterior fossa tumors in childhood. Management of specific tumor types is included as well. 57 references.

  9. Childhood obesity: pathophysiology and treatment.

    Klish, W J

    1995-02-01

    Childhood obesity is among the most difficult problems which pediatricians treat. It is frequently ignored by the pediatrician or viewed as a form of social deviancy, and blame for treatment failure placed on the patients or their families. The definition of obesity is difficult. Using total body electrical conductivity (TOBEC) technology, total body fat ranges between 12% and 30% of total body weight in normal children and adolescents. This is influenced not only by age, but also by physical fitness. Anthropometry is the easiest way to define obesity. Children whose weight exceeds 120% of that expected for their height are considered overweight. Skinfold thickness and body mass index are indices of obesity that are more difficult to apply to the child. Childhood obesity is associated with obese parents, a higher socioeconomic status, increased parental education, small family size and a sedentary lifestyle. Genetics also clearly plays a role. Studies have demonstrated that obese and non-obese individuals have similar energy intakes implying that obesity results from very small imbalances of energy intake and expenditure. An excess intake of only 418 kJ per day can result in about 4.5 kg of excess weight gain per year. Small differences in basal metabolic rate or the thermic effects of food may also account for the difference in energy balance between the obese and non-obese. In the Prader Willi Syndrome, there appears to be a link between appetite and body fatness. When placed on growth hormone, lean body mass increases, body fat decreases, sometimes to normal, and appetite becomes more normal.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Photodynamic therapy (PDT has been used for treatment of various intraocular tumors including choroidal hemangioma, vasoproliferative tumor, amelanotic choroidal melanoma and choroidal neovascular membrane due to choroidal osteoma. This case report documents the effect of PDT for a presumed acquired retinal astrocytoma. A 42-year-old female with a juxtapapillary acquired astrocytoma was treated with a single session of PDT using standard parameters. The tumor showed dramatic regression over 6 months into a fibrotic scar. It remained regressed and stable with 20/20 vision after 51 months of follow-up. We believe that PDT can be used as a primary treatment for acquired retinal astrocytoma.

    Full Text Available CONTEXT: Low-grade astrocytomas are intracerebral lesions of relatively high frequency in the under-18 pediatric population. They often present indolent behaviour, and complete surgical resection is the choice treatment. In cases where the surgery is not possible, chemotherapy and radiotherapy may be used. Medical reports do not recommend examination of the spinal cord at diagnosis or during treatment, since the risk of dissemination of the lesion to the spine is minimal according to medical experience. We describe here four cases of children with low-grade astrocytoma with aggressive dissemination to the neuroaxis.CONTEXTO: Gliomas de baixo grau de malignidade são lesões intracerebrais relativamente freqüentes na população pediátrica menor de 18 anos de idade. Eles freqüentemente são indolentes em seu comportamento e a ressecção cirúrgica completa é o tratmento de eleição. Nos casos em que a cirurgia não é possível, a quimioterapia e a radioterapia podem ser utilizadas. Relatos da literatura não recomendam a avaliação radiológica da coluna espinhal ao diagnóstico ou durante o tratamento, desde que o risco de disseminação destas lesões para a coluna é considerado mínimo. Descrevemos aqui quatro casos de crianças com gliomas de baixo grau de malignidade com disseminação agressiva para o neuroeixo.

    Full Text Available Background. This case highlights the importance of recognising multiple pathologies within the eye which may not necessarily be linked. Both birdshot retinochoroiditis and astrocytoma are rare conditions. The case underlines the need for early identification and treatment of birdshot retinochoroiditis with steroids and disease modifying drugs. Astrocytoma in the absence of tuberous sclerosis is also uncommon. Case Presentation. A 36-year-old male presented with 3-month history of bilateral progressive flashing lights and floaters. He was systemically well with no significant past medical history. Fundal examination revealed retinal vasculitis and active creamy lesions in the choroid radiating from the optic nerve. In the supranasal periphery of the right eye there was a raised white, jagged lesion protruding into the vitreous. Fluorescein angiogram and indocyanine green showed marked venous vasculitis, hypofluorescence, and disc leakage in keeping with birdshot retinochoroiditis. The supranasal lesion features were in keeping with astrocytoma and this was thought to be a coincidental finding. Conclusions. Retinal astrocytoma may be present as an isolated ocular finding; however, patients must still be investigated for tuberous sclerosis which is the most common association. Birdshot retinochoroiditis typically responds well to steroid therapy, and disease modifying drugs should be considered as soon as possible.

    Full Text Available The surgical management of craniopharyngioma in children has been one of the most controversial topics in pediatric neurosurgery. In theory, based on its benign histology total surgical excision could provide a cure. However, the therapeutic goals for pediatric craniopharyngioma are not only the cure of the disease but also the preservation of function. It has been widely established that in some particular cases total excision could leads to inacceptable damages, especially those linked to hypothalamic functions. During the last 15 years, we observed worldwide a growing advocacy for less-invasive pediatric craniopharyngioma resection supported by international consensus conferences. The state-of-the-art in the surgical management of some craniopharyngioma is now turning to multi-modality treatment strategies (combination surgery and radiotherapy aiming to limit morbidiy. Recent literature and our own experience helped to develop risk-adapted treatment strategies at initial diagnosis, respecting hypothalamic structures to provide optimal quality of life for these children. Following new algorithms of treatment, preliminary results with intention to spare the hypothalamus seem to be encouraging but the long-term clinical outcome in terms of post irradiation complications and relapse management is currently unknown.

    Full Text Available Pilocytic astrocytoma (PA is the most frequently encountered glial tumor (glioma or astrocytoma in children. Recent studies have identified alterations in the BRAF serine/threonine kinase gene as the likely causative mutation in these childhood brain tumors. The majority of these genetic changes involve chromosome 7q34 tandem duplication, resulting in aberrant BRAF fusion transcripts. In this paper, we describe a novel KIAA1549:BRAF fusion transcript in a sporadic PA tumor associated with increased ERK activation and review the spectrum of BRAF genetic alterations in this common pediatric low-grade central nervous system neoplasm.

    Despite the existence of a government-run tuberculosis (TB) control program, the current nationwide burden of TB continues to be a public health problem in Taiwan. Intense current and previous efforts into diagnostic, therapeutic, and preventive interventions have focused on TB in adults, but childhood TB has been relatively neglected. Children are particularly vulnerable to severe disease and death following infection, and children with latent infections become reservoirs for future transmission following disease reactivation in adulthood, thus fueling future epidemics. Additional research, understanding, and prevention of childhood TB are urgently needed. This review assesses the epidemiology, diagnosis, treatment, and relevant principles of TB vaccine development and presents efficacy data for the currently licensed vaccines.

    Full Text Available Abstract Background δ-Catenin (CTNND2, which encodes a scaffold protein in humans, has been found in a few malignancies. However, the expression pattern and contribution of δ-catenin to astrocytoma progression are unclear. Methods We investigated δ-catenin expression in human astrocytoma samples and its function in astrocytoma cell lines using immunohistochemistry, siRNA knockdown, transfection, MTT, transwell migration and Rac1 pulldown techniques. Results δ-Catenin protein expression was detected in cytoplasm of astrocytoma cells by immunohistochemistry. Analysis showed that grade I astrocytoma (0%, 0/11 and glial cells from normal brain tissue exhibited negative staining. δ-Catenin expression was significantly higher in grade III-IV (35%, 29/84 compared to grade II astrocytoma cells (18%, 11/61; p CTNND2 overexpression promoted proliferation, invasion and Rac1 activity of U251 astrocytoma cells. Treatment of δ-catenin-transfected cells with a Rac1 inhibitor decreased Rac1 activity and invasion. δ-Catenin knockdown in U87 glioblastoma cell decreased cell proliferation, invasion and Rac1 activity. Conclusion The results suggest that δ-catenin expression is associated with the malignant progression of astrocytoma and promotes astrocytoma cell invasion through upregulation of Rac1 activity. δ-Catenin expression levels may serve as a useful marker of the biological behavior of astrocytoma cells.

    A pilomyxoid astrocytoma (PMA) is a recently identified low-grade neoplasm that was previously classified as a pilocytic astrocytoma (PA), yet demonstrates unique histological features and more aggressive behavior. Although a PMA is generally a tumor of early childhood and typically occurs in the hypothalamic/chiasmatic region, it can mimic cortical tumors, especially in adults. We report the MR findings of a PMA presenting as a cortical brain tumor in an adult with neurofibromatosis 1 (NF1)

    2008-02-01

    Discussions of pediatric nutrition and cancer usually focus on important issues of ensuring an adequate nutrient intake (enteral and parenteral) during and after the early treatment phase of care. However, information is available that suggests that vitamin status may have additional roles in the care of children with cancer. Over the last decade, investigators have reported findings that suggest that maternal preconception and perinatal vitamin intake and status influence the cancer risk of the infant and child. Others have shown a relationship between vitamin and antioxidant status and the prevalence and severity of adverse side effects for children undergoing chemotherapy. Vitamin D has potential anti-cancer activity and vitamin D status is suboptimal in many children in North America. Each of these issues is briefly presented from a perspective of prevention and treatment of childhood cancer.

    Diphenylhydantoin is a well known anticonvulsant used primarily in the treatment of epilepsy. The prophylactic use of diphenylhydantoin has been suggested for certain cerebral metastases, and it is routinely administered to prevent seizures induced by intracranial neoplasms and/or surgery. Patients with malignant gliomas treated with diphenylhydantoin frequently receive radiation therapy. The effects of a clinical concentration of diphenylhydantoin in combination with gamma radiation was investigated using the C6 astrocytoma cell line in both monolayer and three dimensional multicellular spheroid cultures. Diphenylhydantoin at 7.2 X 10(-5) M (20 micrograms/ml) significantly increased the doubling time (23%) of the C6 astrocytoma cells in monolayer, but did not affect their survival as measured by plating efficiency. No changes were seen in spheroid growth or plating efficiency of the cells dissociated from spheroids at this concentration. Diphenylhydantoin at the clinical concentration tested was not associated with an alteration in radiation sensitivity of C6 astrocytoma cells in monolayer or three dimensional multicellular spheroid cultures.

  7. Magnitude of Treatment Abandonment in Childhood Cancer.

    Full Text Available Treatment abandonment (TxA is recognized as a leading cause of treatment failure for children with cancer in low-and-middle-income countries (LMC. However, its global frequency and burden have remained elusive due to lack of global data. This study aimed to obtain an estimate using survey and population data.Childhood cancer clinicians (medical oncologists, surgeons, and radiation therapists, nurses, social workers, and psychologists involved in care of children with cancer were approached through an online survey February-May 2012. Incidence and population data were obtained from public sources. Descriptive, univariable, and multivariable analyses were conducted.602 responses from 101 countries were obtained from physicians (84%, practicing pediatric hematology/oncology (83% in general or children's hospitals (79%. Results suggested, 23,854 (15% of 155,088 children 6% were outside the capital. Lower national income category, higher reliance on out-of-pocket payments, and high prevalence of economic hardship at the center were independent contextual predictors for TxA ≥ 6% (p<0.001. Global survival data available for more developed and less developed regions suggests TxA may account for at least a third of the survival gap between HIC and LMC.Results show TxA is prevalent (compromising cancer survival for 1 in 7 children globally, confirm the suspected high burden of TxA in LMC, and illustrate the negative impact of poverty on its occurrence. The present estimates may appear small compared to the global burden of child death from malnutrition and infection (measured in millions. However, absolute numbers suggest the burden of TxA in LMC is nearly equivalent to annually losing all kids diagnosed with cancer in HIC just to TxA, without even considering deaths from disease progression, relapse or toxicity-the main causes of childhood cancer mortality in HIC. Results document the importance of monitoring and addressing TxA as part of childhood

    Protein tyrosine nitration is involved in the pathogenesis of highly fatal astrocytomas, a type of brain cancer. To understand the molecular mechanisms of astrocytomas and to discover new biomarkers/therapeutic targets, we sought to identify nitroproteins in human astrocytoma tissue. Anti-nitrotyrosine immunoreaction-positive proteins from a high-grade astrocytoma tissue were detected with two-dimensional gel electrophoresis (2DGE)-based nitrotyrosine immunoblots, and identified with liquid chromatography-tandem mass spectrometry (LC-MS/MS). Fifty-seven nitrotyrosine immunopositive protein spots were detected. A total of 870 proteins (nitrated and non-nitrated) in nitrotyrosine-immunopositive 2D gel spots were identified, and 18 nitroproteins and their 20 nitrotyrosine sites were identified with MS/MS analysis. These nitroproteins participate in multiple processes, including drug-resistance, signal transduction, cytoskeleton, transcription and translation, cell proliferation and apoptosis, immune response, phenotypic dedifferentiation, cell migration, and metastasis. Among those nitroproteins that might play a role in astrocytomas was nitro-sorcin, which is involved in drug resistance and metastasis and might play a role in the spread and treatment of an astrocytoma. Semiquantitative immune-based measurements of different sorcin expressions were found among different grades of astrocytomas relative to controls, and a semiquantitative increased nitration level in high-grade astrocytoma relative to control. Nitro-β-tubulin functions in cytoskeleton and cell migration. Semiquantitative immunoreactivity of β-tubulin showed increased expression among different grades of astrocytomas relative to controls and semiquantitatively increased nitration level in high-grade astrocytoma relative to control. Each nitroprotein was rationalized and related to the corresponding functional system to provide new insights into tyrosine nitration and its potential role in the

    1991-03-01

    The authors evaluated the risk of development of cholelithiasis in 6050 patients treated at a single hospital for various childhood cancers with different therapeutic modalities, including chemotherapy, surgery, radiation therapy, and bone marrow transplantation, from 1963 to 1989. Patients with underlying chronic hemolytic anemia or preexisting gallstones were excluded. Nine female and seven male patients with a median age of 12.4 years (range, 1.2 to 22.8 years) at diagnosis of primary cancer had gallstones develop 3 months to 17.3 years (median, 3.1 years) after therapy was initiated. Cumulative risks of 0.42% at 10 years and 1.03% at 18 years after diagnosis substantially exceed those reported for the general population of this age group. Treatment-related factors significantly associated with an increased risk of cholelithiasis were ileal conduit, parenteral nutrition, abdominal surgery, and abdominal radiation therapy (relative risks and 95% confidence intervals = 61.6 (27.9-135.9), 23.0 (9.8-54.1), 15.1 (7.1-32.2), and 7.4 (3.2-17.0), respectively). There was no correlation with the type of cancer, nor was the frequency of conventional predisposing features (e.g., family history, obesity, use of oral contraceptives, and pregnancy) any higher among the affected patients in this study than in the general population. Patients with cancer who have risk factors identified here should be monitored for the development of gallstones.

    Childhood Obesity is associated with a wide range of serious health complications and constitutes an increased risk of premature syndromes, including diabetes or heart diseases. Its treatment seems to be complicated. So, in order to help parents we have developed a system that will try to make easier the process of choosing foodstuff for overweight and obese children at the supermarket. To interact with the system, Near Field Communication mobile phones and tags are used. Those tags would have nutritional information such as energy or fat contain of each product. When the interaction takes place, the system will generate an alert determining if the product is adequate for the user diet or not. Decision will be influenced by specific prescript diets, which would have been previously generated by the system based on user profile parameters. At the same time the diet is established, the shopping list would be generated automatically. Therefore, the user could download and print both things at home easily by the PC application. The system also takes into account physical activity of the user. Children mobile phone includes an accelerometer that will detect and collect user activities in order to modify calorical requirements and, if necessary, to change physical activity too. In the future, it would be possible to extend this project system for adults, managing diets not just for obese and overweight, but also to diabetic or celiac people.

    Kruger Mathew M

    2003-09-01

    Full Text Available Abstract Background Astrocytomas are the most common type of primary central nervous system tumors. They are frequently associated with genetic mutations that deregulate cell cycle and render these tumors resistant to apoptosis. STAT3, signal transducer and activator of transcription 3, participates in several human cancers by inducing cell proliferation and inhibiting apoptosis and is frequently activated in astrocytomas. Methods RNA interference was used to knockdown STAT3 expression in human astrocytes and astrocytoma cell lines. The effect of STAT3 knockdown on apoptosis, cell proliferation, and gene expression was then assessed by standard methods. Results We have found that STAT3 is constitutively activated in several human astrocytoma cell lines. Knockdown of STAT3 expression by siRNA induces morphologic and biochemical changes consistent with apoptosis in several astrocytoma cell lines, but not in primary human astrocytes. Moreover, STAT3 is required for the expression of the antiapoptotic genes survivin and Bcl-xL in the A172 glioblastoma cell line. Conclusion These results show that STAT3 is required for the survival of some astrocytomas. These studies suggest STAT3 siRNA could be a useful therapeutic agent for the treatment of astrocytomas.

  1. Parental involvement: contribution to childhood anxiety and its treatment.

    Wei, Chiaying; Kendall, Philip C

    2014-12-01

    Anxiety disorders are prevalent in youth. Despite demonstrated efficacy of cognitive behavioral therapy (CBT), approximately 40% of anxiety-disordered youth remain unresponsive to treatment. Because developmental and etiological models suggest that parental factors are relevant to the onset and maintenance of childhood anxiety, researchers have proposed and investigated family-based interventions with increased parent work in treatment, aiming to improve the efficacy of treatment for childhood anxiety. However, contrary to what theoretical models suggest, data to date did not indicate additive benefit of family-based CBT in comparison with child-centered modality. Is parent/family involvement unnecessary when treating childhood anxiety disorders? Or could there be the need for specificity (tailored family-based treatment) that is guided by a revised conceptualization that improves the implementation of a family-based intervention? The current review examines (1) relevant parental factors that have been found to be associated with the development and maintenance of childhood anxiety and (2) interventions that incorporate parental involvement. Relevant findings are integrated to formulate a "targeted" treatment approach for parental involvement in CBT for youth anxiety. Specifically, there is potential in the assessment of parent/family factors prior to treatment (for appropriateness) followed by a target-oriented implementation of parent training.

    2014-08-01

    The paucity of evidence and detail in the literature regarding speech treatment for children with dysarthria due to cerebral palsy (CP) renders it difficult for researchers to replicate studies and make further inroads into this area in need of exploration. Furthermore, for speech-language pathologists (SLPs) wishing to follow treatments that the literature indicates have promise, little guidance is available on the details of the treatments that yielded the positive results. The present article details the implementation of two treatment approaches in speech treatment research for children with dysarthria: Speech Systems Intelligibility Treatment (SSIT) and the Lee Silverman Voice Treatment LOUD (LSVT LOUD). Specific strategies, primarily for treatment, but also for outcome measurement and acoustic analysis of dysarthric speech, are described. These techniques are provided for researchers and clinicians to consider implementing in order to advance speech treatment for this population. New data from research using these approaches are presented, including findings of acoustic vowel space changes following both speech treatments.

    We describe the effectiveness of rehabilitative training for a neuropsychological deficit following the removal and treatment of a fibrillary astrocytoma (Grade II) in a young man. The rehabilitative training was based on cognitive and motivational techniques and has been carried out for a period of 3 months (2 times per week). The results, even if limited to a single case, seem to support the idea that cognitive rehabilitation should facilitate the brain's reorganization of basic cognitive functions in the neuro-oncologic field.

    Patients with unresectable glioblastoma or anaplastic astrocytoma have a dismal prognosis. The role of neoadjuvant chemotherapy prior to irradiation in these patients has been studied primarily in non-randomized studies. We have compared the effect of neoadjuvant chemotherapy plus radiotherapy versus concomitant radiotherapy plus temozolomide in a retrospective analysis of two consecutive series of patients in whom surgery consisted of biopsy only. From 2003 to 2005, 23 patients received two cycles of temozolomide plus cisplatin followed by radiotherapy (Cohort 1), and from 2006 to 2010, 23 additional patients received concomitant radiotherapy and temozolomide followed by adjuvant temozolomide (Cohort 2). In Cohort 1, 91.3 % of patients received all planned chemotherapy cycles. Progression-free and overall survival were 3.3 and 8.5 months, respectively. In Cohort 2, progression-free and overall survival were 5.1 and 11.2 months, respectively. No differences between the two groups were observed in rate of completion of radiotherapy, progression-free or overall survival. MGMT methylation was assessed in 91.3 % of patients. In Cohort 1, patients without MGMT methylation showed a trend towards shorter progression-free survival (P = 0.09), while in Cohort 2, patients without MGMT methylation had longer progression-free survival (P = 0.04). In the overall patient population, neoadjuvant temozolomide plus cisplatin had neither a positive nor negative influence on outcome. However, our findings indicate that patients with methylated MGMT may derive greater benefit from neoadjuvant temozolomide than those with unmethylated MGMT.

    Full Text Available Chronic Constipation is a debilitating condition that is often associated with different abdominal problem. It can cause distress for the child and family and can result in emotional disturbance and family problem. Based on the current algorhytm, the treatment of chronic constipation consists of 4 important phases, 1: education, 2: disimpaction, 3: prevention of re-accumulation of feces and 4: follow up. Challenges in treatment are related to many issues: a    Discussing the importance of problem for parents, b    Family concern about safety and side effects of drugs, c    Adherence to long term treatment, which is often crucial but unacceptable by family, d    Amelioration of withdrawal behavior in toddlers group which don’t understand the facts, e    Planning a appropriate diet for constipation which is again unacceptable by children, f     Cost of treatment g    Anismus Besides of known treatment consist of various drugs:   Biofeedback is one of the approaches that have proven benefits but with less emphasis and introduction, so application of this obsolete method needs further works. Tegaserod, a selective agonist that acts at 5-HT4 receptors and increases small bowel transit, stimulates intestinal secretion and inhibits visceral afferent responses has proven effective in the treatment of chronic constipation in adults.  In children with hard stools, 5-HT4 agonist might benefit children with constipation and tendency to form hard stools, and large rectal masses. The role of this promising new agent in pediatric constipation has to be established in future studies. Pre and Probiotics:  Non-digestible oligosaccharides consist mainly of fructooligosaccharides (FOS. FOS reduces fecal pH, increases the water, holding capacity of stool and fecal weight and decreases intestinal transit time. Furthermore, it has prebiotic effects by selectively stimulating the growth of probiotics bacteria, such as bifidobacteria. Surgery

    Full Text Available Obesity is one of today’s most diffused and severe public health problems worldwide. It affects both adults and children with critical physical, social and psychological consequences. The aim of this review is to appraise the studies that investigated the effects of motivational interviewing techniques in treating overweight and obese children. The electronic databases PubMed and PsychINFO were searched for articles meeting inclusion criteria. The review included studies based on the application of MI components and having the objective of changing BMI in overweight or obese children from age 2 to age 11. Six articles have been selected and included in this review. Three studies reported that MI had a statistically significant positive effect on BMI and on secondary obesity-related behaviour outcomes. MI can be applicable in the treatment of overweight and obese children, but its efficacy cannot be proved given the lack of studies carried out on this specific sample.

    Silver-Russell syndrome is a rare genetically heterogeneous disorder in which patients demonstrate intrauterine and postnatal growth retardation, triangular facies, excessive sweating during early childhood, late closure of the anterior fontanelle and skeletal asymmetry. An association with malignancy exists and only one previous intracranial tumour has been reported, a craniopharyngioma. We report the first case of Silver-Russell syndrome associated with a supratentorial juvenile pilocytic astrocytoma.

    Food allergy is a growing public health concern in the United States that affects an estimated 8% of children. Food allergy is defined as an adverse health effect arising from a specific immune response that occurs reproducibly on exposure to a specific food. Nearly 40% of children with food allergy have a history of severe reactions that if not treated immediately with proper medication can lead to hospitalization or even death. The National Institute of Allergy and Infectious Diseases (NIAID) convened an expert panel in 2010 to develop guidelines outlining evidence-based practices in diagnosing and managing food allergy. The purpose of this review is to aid clinicians in translating the NIAID guidelines into primary care practice and includes the following content domains: (1) the definition and mechanism of childhood food allergy, (2) differences between food allergy and food intolerance, (3) the epidemiology of childhood food allergy in the United States, (4) best practices derived from the NIAID guidelines focused on primary care clinicians' management of childhood food allergy, (5) emerging food allergy treatments, and (6) future directions in food allergy research and practice. Articles focused on childhood food allergy were considered for inclusion in this review. Studies were restricted to the English language and to those published within the past 40 years. A cross-listed combination of the following words, phrases, and MeSH terms was searched in PubMed and Google Scholar to identify relevant articles: food allergy, food hypersensitivity, child, pediatric, prevalence, and epidemiology. Additional sources were identified through the bibliographies of the retrieved articles.

    Full Text Available Pilocytic astrocytoma (PA is a benign tumor that rarely spread along the neuraxis. At the moment there are no more than five cases of leptomeningeal dissemination (LD from PA at diagnosis described in the literature. Different patterns of presentation or recurrence may be noted: local recurrence, malignant transformation, multicentric disease or metastatic disease. LD and multicentric disease can be distinct pathological entities. We report two cases and analyse literature, emphasizing leptomeningeal spread at presentation. Hydrocephalus, biopsy and parcial ressection are likely to be favorable factors to the occurrence of LD. Otherwise, LD may be part of natural history of PA, as evidenced by its ocurrence in non-treated cases.Astrocitoma pilocítico (AP é tumor benigno que raramente se dissemina ao longo do neuroeixo. Até o momento não há mais que cinco casos de AP que se tenham apresentado com disseminação leptomeníngea (DL descritos na literatura. Diferentes padrões de apresentação ou recorrência podem ser observados: recorrência local, transformação maligna, doença multicêntrica ou doença metastática. DL e doença multicêntrica podem ser entidades diferentes. Relatamos dois casos e analisamos a literatura. Hidrocefalia, biópsia e ressecção parcial são provavelmente fatores predisponentes à DL. Por outro lado, DL pode ser parte da história natural de AP, como pode ser evidenciado pela sua ocorrência em casos não tratados.

    The prevalence of food allergy in childhood increased in the last decades, especially in Westernized countries where this phenomenon has been indicated as a second wave of the allergic epidemic. In parallel, scientific interest also increased with the effort to explain the reasons of this sudden rise and to identify potential protective and risk factors. A great attention has been focused on early exposures to allergenic foods, as well as on other nutritional factors or supplements that may influence the immune system in a positive direction. Both interventions on maternal diet before birth or during breastfeeding and then directly on infant nutrition have been investigated. Furthermore, the natural history of food allergy also seems to be changing over time; IgE-mediated cow's milk allergy and egg allergy seem to be more frequently a persistent rather than a transient disease in childhood, as described in the last years. Food avoidance and the emergency drugs in case of an adverse event, such as epinephrine self-injector, are currently the first-line treatment in patients with food allergies, with a resulting impairment in the quality of life and social behaviour. During the last decade, oral immunotherapy emerged as an optional treatment with remarkable results, offering a novel perspective in the treatment for and management of food allergy.

    Secondary osteosarcoma arising after the treatment of hematologic malignancies other than Hodgkin's lymphoma is rare. We report two cases of secondary osteosarcoma arising after treatment for childhood hematologic malignancies (non-Hodgkin's lymphoma and lymphoblastic leukemia). A 10-year-old boy, at the age of 3, was diagnosed with non-Hodgkin's lymphoma. He received chemotherapy, radiation, and bone-marrow transplantation and then was in complete remission. At 6 years, he complained of increasing pain of the right thigh and was diagnosed with osteoblastic osteosarcoma. A 26-year-old man, at the age of 6, was diagnosed as having acute lymphoblastic leukemia (ALL). He received chemotherapy, radiation, and peripheral blood stem cell transplantation (PBSCT). At 11 years after PBSCT, he visited with the complaint of left lumbar swelling. He was diagnosed with chondroblastic osteosarcoma. In both cases alkaline phosphatase (ALP) had already increased prior to the onset of the symptom. We should rule out secondary osteosarcoma at the abnormal elevation of ALP during clinical follow-up of patients after treatment of childhood hematologic malignancies. PMID:19961270

    CP is the most common cause of chronic disability in childhood occurring in 2–2.5/1000 births. It is a severe disorder and a significant number of patients present cognitive delay and difficulty in walking. The use of botulinum toxin (BTX) has become a popular treatment for CP especially for spastic and dystonic muscles while avoiding deformity and pain. Moreover, the combination of physiotherapy, casting, orthotics and injection of BTX may delay or decrease the need for surgical intervention while reserving single-event, multi-level surgery for fixed musculotendinous contractures and bony deformities in older children. This report highlights the utility of BTX in the treatment of cerebral palsy in children. We include techniques for administration, side effects, and possible resistance as well as specific use in the upper and lower limbs muscles. PMID:26924985

    Background Recent studies have discovered that nuclear translocation of nerve growth factor (NGF) and its receptor fragments function differently from the traditional model. This study aimed to uncover the nuclear expression of NGF in astrocytoma and its biological significance.Methods Ninety-four paraffin-embedded astrocytoma specimens were subjected to immunohistochemical (IHC) and hemotoxylin & eosin (HE) staining. Preoperative cerebrospinal fluid (CSF) specimens and intraoperative snap-frozen astrocytoma tissues were assayed for NGF expression by ELISA and Western blotting. The outcome of patients who contributed samples was tracked. Each ten tissue samples from patients with traumatic brain injury who had received decompression surgery and CSF samples from patients undergoing spinal anesthesia but with no history of nervous system disease were taken as control.Results NGF-positive immunoreactive products were distributed in both the cytoplasm and nucleus of astrocytoma, but were only located in the cytoplasm of traumatic brain injury (TBI) tissue. NGF nuclear-positive rate (NPR) of grades Ⅲ-Ⅳ astrocytomas (70.0%) was higher than that of grades Ⅰ-Ⅱ astrocytoma (28.6%, P<0.05). NGF-NP expression positively correlated with the NGF concentration in cerebrospinal fluid (CSF) (r=0.755, P<0.01). Kaplan-Meier survival analysis indicated that the median survival time was 25 months for NGF-NP astrocytoma grade Ⅰ-Ⅱ patients and 42 months in NGF nuclear negative (NGF-NN) astrocytoma grade Ⅰ-Ⅱ patients (P<0.05). In astrocytoma Ⅲ-Ⅳ patients, the median survival was 7 months for NGF-NP patients and 24 months for NGF-NN patients (P<0.01). Two types of NGF with molecular weights of 13 and 36 kDa were present in astrocytoma, but only the 36 kDa NGF was found in the CSF. NGF expression elevated as the malignancy increased.Conclusions NGF-NP expression and NGF level in CSF were significant prognostic factors in astrocytoma patients.Because of the easy

    Malignant astrocytomas have been found to express P-glycoprotein (Pgp, mdr1 gene product). It was hypothesized that in addition to conferring multidrug resistance, Pgp is intimately associated with the development of astrocytomas. Accordingly, we studied the effect of PSC 833 (PSC, Novartis), a potent inhibitor of Pgp, on the growth of Pgp-expressing astrocytoma cells. The results showed that in all the cell lines tested, PSC (10-60 microM) inhibited the growth as well as induced cell death. Cells exposed to PSC exhibited DNA ladder characteristic of apoptosis. PSC-induced cell death could be reversed by Z-VAD-fmk, a general caspase inhibitor, indicating that PSC-induced cell death was characteristic of caspase-mediated apoptosis. These results suggest a novel therapeutic strategy in the treatment of malignant astrocytomas by inhibitors of Pgp.

    A 72-year-old male presented with a pilocytic astrocytoma in the velum interpositum manifesting as a 5-day history of dizziness attacks and unstable gait. Computed tomography and T1-weighted magnetic resonance imaging with gadolinium enhancement demonstrated a small, homogeneously enhanced mass in the velum interpositum. The tumor was removed subtotally, and the structure of the splenium was intact. The histological diagnosis was pilocytic astrocytoma. The MIB-1 growth fraction was 5%. The tumor may have originated from the splenium or the thalamus. The aggressive histology indicates the need for close neuroimaging follow-up.

They are frequently associated with considerable and progressive neurological disability and are ultimately intractable to all forms of treatment. Temozolomide (TMZ is a new second generation DNA alkylating agent that has become part of malignant astrocytoma management paradigms because of its proven efficacy, ease of administration, and favorable toxicity profile. Aims: To review the role of TMZ in the management of malignant astrocytomas (World Health Organization grades III and IV including newly diagnosed (n and recurrent (r anaplastic astrocytomas (AA and glioblastomas.Evidence review: A series of pivotal clinical trials have established a role for TMZ in the treatment of malignant astrocytomas. A large phase II trial examining the role of TMZ in rAA showed a response rate of 35%, and a 6-month progression-free survival of 46%. This led to the accelerated approval of TMZ by the FDA and the EU for the treatment of rAA. Evidence for a role of TMZ in nAA is currently limited but research is ongoing in this area. The role of TMZ in the management of glioblastoma at the time of recurrence (rGBM is less impressive but evidence for its activity was demonstrated in two large phase II trials that led to the approval of TMZ for this indication in Europe and Canada but not in the US. A recent large prospective randomized phase III trial showed that the addition of TMZ during and after radiation therapy (RT in newly diagnosed (nGBM patients prolonged median overall survival by 2.5 months; perhaps more importantly, the 2-year survival rate for patients

    Purpose: To determine the patient, tumor, and treatment characteristics of patients with pilocytic astrocytoma (PA) and leptomeningeal dissemination (LMD). Methods and Materials: A PubMed search of English-language studies pertaining to PA with LMD was performed using a combination of keywords that included juvenile pilocytic astrocytoma, low-grade astrocytoma, low-grade glioma, leptomeningeal dissemination, neuraxis spread, and radiotherapy. We found 26 studies with 58 patients between 1976 and 2005 that met these criteria. Results: The median survival for PA patients with LMD was 65 months. The 1-, 2-, and 5-year overall survival (OS) rate after the diagnosis of LMD was 81.1%, 75.7%, and 55.5%. The 1-, 2-, and 5-year progression-free survival (PFS) rate after the diagnosis of LMD was 69.3%, 66.5%, and 34.6%, respectively. Age, gender, primary site location, timing of LMD presentation (synchronous vs. metachronous), and LMD location did not significantly influence OS or PFS. No statistically significant difference was found in OS or PFS between the chemotherapy and radiotherapy groups. Likewise, no difference was found in OS or PFS according to the use of craniospinal irradiation vs. less extensive RT fields. Conclusions: Approximately one-half of PA patients were alive 5 years after the diagnosis of LMD. Both chemotherapy and radiotherapy have efficacy against LMD. Although the use of craniospinal irradiation did not have an effect on PFS, the patient numbers were small and a larger number treated with craniospinal irradiation is needed to determine its efficacy.

    Full Text Available Abstract Background Oxygen therapy is recommended for all of the 1.5 – 2.7 million young children who consult health services with hypoxemic pneumonia each year, and the many more with other serious conditions. However, oxygen supplies are intermittent throughout the developing world. Although oxygen is well established as a treatment for hypoxemic pneumonia, quantitative evidence for its effect is lacking. This review aims to assess the utility of oxygen systems as a method for reducing childhood mortality from pneumonia. Methods Aiming to improve priority setting methods, The Child Health and Nutrition Research Initiative (CHNRI has developed a common framework to score competing interventions into child health. That framework involves the assessment of 12 different criteria upon which interventions can be compared. This report follows the proposed framework, using a semi-systematic literature review and the results of a structured exercise gathering opinion from experts (leading basic scientists, international public health researchers, international policy makers and representatives of pharmaceutical companies, to assess and score each criterion as their “collective optimism” towards each, on a scale from 0 to 100%. Results A rough estimate from an analysis of the literature suggests that global strengthening of oxygen systems could save lives of up to 122,000 children from pneumonia annually. Following 12 CHNRI criteria, the experts expressed very high levels of optimism (over 80% for answerability, low development cost and low product cost; high levels of optimism (60-80% for low implementation cost, likelihood of efficacy, deliverability, acceptance to end users and health workers; and moderate levels of optimism (40-60% for impact on equity, affordability and sustainability. The median estimate of potential effectiveness of oxygen systems to reduce the overall childhood pneumonia mortality was ~20% (interquartile range: 10-35%, min

    There is a consensus that interventions to prevent and treat childhood obesity should involve the family; however, the extent of the child's involvement has received little attention. The goal of the present study was to evaluate the relative efficacy of treating childhood obesity via a family-based health-centred intervention, targeting parents alone v. parents and obese children together. Thirty-two families with obese children of 6-11 years of age were randomised into groups, in which participants were provided for 6 months a comprehensive educational and behavioural programme for a healthy lifestyle. These groups differed in their main agent of change: parents-only v. the parents and the obese child. In both groups, parents were encouraged to foster authoritative parenting styles (parents are both firm and supportive; assume a leadership role in the environmental change with appropriate granting of child's autonomy). Only the intervention aimed at parents-only resulted in a significant reduction in the percentage overweight at the end of the programme (P=0.02) as well as at the 1-year follow-up meeting. The differences between groups at both times were significant (Pparents-only group. In both groups, the parents' weight status did not change. Regression analysis shows that the level of attendance in sessions explained 28 % of the variability in the children's weight status change, the treatment group explained another 10 %, and the improvement in the obesogenic load explained 11 % of the variability. These results suggest that omitting the obese child from active participation in the health-centred programme may be beneficial for weight loss and for the promotion of a healthy lifestyle among obese children.

    Low-grade astrocytomas comprise about 30 % of the central nervous system tumors in children. Several investigations have searched a correlation between the BRAF gene fusions alterations and mutations at IDH1 and IDH2 genes in low grade pediatric astrocytomas. This study identified the expression of KIAA1549-BRAF fusion gene and BRAF V600E mutation, mutations at exon 4 of the IDH1 and IDH2 genes in samples of pilocytic astrocytomas (PA) and grade-II astrocytomas (A-II) pediatric patients. The correlation between these alterations and the clinical profile of the patients was also evaluated. Eighty-two samples of low-grade astrocytomas (65 PA and 17 A-II) were analyzed by PCR and sequencing for each of the targets identified. We identified the KIAA1549-BRAF fusion transcript in 45 % of the samples. BRAF V600E and BRAFins598T mutations were detected in 7 and 1 % of the samples, respectively. Mutations in the R132/R172 residues of the IDH1/IDH2 genes were detected in only two samples, and the G105G polymorphism (rs11554137:C>T) was identified in ten patients. Additionally, we observed two mutations out of the usual hotspots at IDH1 and IDH2 genes. We observed a smaller frequency of mutations in IDHs genes than previously described, but since the prior studies were composed of adult or mixed (adults and children) samples, we believe that our results represent a relevant contribution to the growing knowledge in low grade childhood astrocytomas.

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

    Pilomyxoid astrocytoma (PMA) is a newly identified variant of pilocytic astrocytoma (PA). We report three cases of PMA with comparison to seven cases of PA in terms of their clinicopathological features. The three cases occurred at the ages of 2, 36 and 6 years, and their tumors were located in the left basal ganglia, the pineal gland, and the cerebellum, respectively. They were diagnosed PMA by surgical specimens that showed a characteristic monomorphous architecture with an angiocentric growth pattern and myxoid background. One patient developed localized relapse at 6 months after the surgery, but the other patients remained alive without tumor progression more than 5 years after treatment. In analysis of the immunohistochemical association in PMA and PA, no specific staining was found to be useful for differential diagnosis of PMA from PA. The expression of biomarkers including O-6-methylguanine-DNA methyltransferase, p53, MIB-1, and EGF receptor neither distinguished PMA from PA nor correlated with outcome. But almost all PMA and PA that demonstrated prominent positivity for nestin showed a high MIB-1 labelling index (LI), and four of these five patients suffered a relapse in the early phase. These results suggest that immunohistochemical expression of nestin and MIB-1 LI may correlate with the aggressiveness of the tumor in PA and PMA.

    Full Text Available Background: Pilomyxoid astrocytoma (PMA has recently been accepted as an aggressive variant of pilocytic astrocytoma with distinct histopathological features. PMAs have been frequently described in the pediatric population with a predilection for the hypothalamic/chiasmatic region. Case Description: A 72-year-old African American male presented with 6 months of memory loss, difficulty expressing himself, and a progressively worsening gait. Magnetic resonance imaging of the brain demonstrated a heterogeneously enhancing cystic mass centered within the cerebellar vermis with mass effect on the fourth ventricle and ventriculomegaly. The patient underwent placement of a ventriculoperitoneal shunt followed by a surgical resection of the lesion, which after immunohistopathologic evaluation, was diagnosed as a World Health Organization grade II PMA. The patient refused further treatment of the lesion and expired 11 months after initial symptom presentation and 4 months after surgery. Conclusion: To our knowledge, this is the first report of PMA of the cerebellar vermis in a previously unreported age group. This case report describes the natural history of this type of tumor in a patient who refused adjuvant therapy following surgical resection.

    PURPOSE: Second malignant neoplasms (SMNs) after diagnosis of childhood acute lymphoblastic leukemia (ALL) are rare events. PATIENTS AND METHODS: We analyzed data on risk factors and outcomes of 642 children with SMNs occurring after treatment for ALL from 18 collaborative study groups between 1980...... and 2007. RESULTS: Acute myeloid leukemia (AML; n = 186), myelodysplastic syndrome (MDS; n = 69), and nonmeningioma brain tumor (n = 116) were the most common types of SMNs and had the poorest outcome (5-year survival rate, 18.1% ± 2.9%, 31.1% ± 6.2%, and 18.3% ± 3.8%, respectively). Five-year survival...... estimates for AML were 11.2% ± 2.9% for 125 patients diagnosed before 2000 and 34.1% ± 6.3% for 61 patients diagnosed after 2000 (P survival estimates for MDS were 17.1% ± 6.4% (n = 36) and 48.2% ± 10.6% (n = 33; P = .005).

    Objective:The aim of this study was to study the clinicopathological and immunohistochemical features of pilo-myxoid astrocytoma (PMA). Methods:The clinical and pathologic features in six cases of PMA were analyzed. Immunohisto-chemical staining for glial fibril ary acidic protein (GFAP), synaptophysin (Syn), Chromogranin A (CgA), cytokeratin (AE1/AE3), epithelial membrane antigen (EMA) and Ki67 was performed on paraf in-embedded sections. Results:Among the six cases, five occurred in female patients, one was male, the age at diagnosis ranged from 2 to 15 years. Four cases were located in the hypothalamic area and optic pathway, one case in the third ventricle, and one case in left parietal lobe. On imaging, PMAs often appears as wel-circumscribed mass. Microscopically, the tumor was composed of monomorphous bipolar (piloid) cells setting in a prominent myxoid background with an angiocentric radiating growth pattern in some areas. PMA lacked biphasic pattern, Rosenthal fibers and eosinophilic granular bodies which were usual y typical in a classic pilocytic astrocytoma (PA). Immunohistochemcal study showed that the tumor cel s were dif usely positive for GFAP. Syn positive staining was observed in one case. The Ki67 labeling index measured less than 5%. Conclusion:PMA is a distinct aggressive variant of pilocytic astrocytoma with special histological and immunohistochemical features. It is typically a rare tumor of early childhood. Im-munohistochemical staining for GFAP and Syn is helpful in dif erential diagnosis.

    Neurotrophins and their receptors of the Trk family play a critical role in proliferation, differentiation and survival of the developing neurons. There are reports on their expression in neoplasms too, namely, the primitive neuroectodermal tumours of childhood, and in adult astrocytic gliomas. The involvement of Trk receptors in tumour pathogenesis, if any, is not known. With this end in view, the present study has examined 10 tumour biopsy samples (identified as astrocytoma, pilocytic astrocytoma and glioblastoma) and peritumoral brain tissue of adult patients, for the presence of Trk A and Trk B receptors, by immunohistochemistry. The nature of the tumour samples was also confirmed by their immunoreactivity (IR) to glial fibrillary acidic protein. In the peritumoral brain tissue, only neurons showed IR for Trk A and Trk B. On the contrary, in the tumour sections, the IR to both receptors was localized in the vast majority of glia and capillary endothelium. There was an obvious pattern of IR in these gliomas: high levels of IR were present in the low-grade (type I and II) astrocytoma; whereas in the advanced malignant forms (WHO grade IV giant cell glioblastoma and glioblastoma multiforme) the IR was very weak. These findings suggest that Trk A and Trk B are involved in tumour pathogenesis, especially in the early stage, and may respond to signals that elicit glial proliferation, and thus contribute to progression towards malignancy.

  18. Inhibition of STAT3 reduces astrocytoma cell invasion and constitutive activation of STAT3 predicts poor prognosis in human astrocytoma.

    Full Text Available Astrocytoma cells characteristically possess high invasion potentials. Recent studies have revealed that knockdown of signal transducers and activators of transcription 3 (STAT3 expression by RNAi induces apoptosis in astrocytoma cell. Nevertheless, the distinct roles of STAT3 in astrocytoma's invasion and recurrence have not been elucidated. In this study, we silenced STAT3 using Small interfering RNAs in two human glioblastoma multiforme (GBM cell lines (U251 and U87, and investigated the effect on GBM cell adhesion and invasion. Our results demonstrate that disruption of STAT3 inhibits GBM cell's adhesion and invasion. Knockdown of STAT3 significantly increased E-cadherin but decreased N-cadherin, vascular endothelial growth factor, matrix metalloproteinase 2 and matrix metalloproteinase 9. Additionally, expression of pSTAT3(Tyr705 correlates with astrocytoma WHO classification, Karnofsky performance status scale score, tumor recurrence and survival. Furthermore, pSTAT3(Tyr705 is a significant prognostic factor in astrocytoma. In conclusion, STAT3 may affect astrocytoma invasion, expression of pSTAT3(Tyr705 is a significant prognostic factor in tumor recurrence and overall survival in astrocytoma patients. Therefore, STAT3 may provide a potential target for molecular therapy in human astrocytoma, and pSTAT3(Tyr705could be an important biomarker for astrocytoma prognosis.

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

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

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

  3. Infertility treatment and umbilical cord length-novel markers of childhood epilepsy?

    Sari Räisänen

    Full Text Available BACKGROUND: Epilepsy is one of the most common neurologic disorders of childhood, affecting about 0.4-0.8% of all children up to the age of 20. METHODOLOGY: A population-based retrospective cohort study. Aim was to determine incidence and identify perinatal and reproductive risk factors of epilepsy in children born between 1989 and 2008 among women (n = 43,389 delivered in Kuopio University Hospital. Risk factors of childhood epilepsy were determined by using logistic regression analysis. PRINCIPAL FINDINGS: The incidence of childhood epilepsy was 0.7% (n = 302 of 43,389. Maternal epilepsy, major congenital anomalies and use of assisted reproductive technology (ART were associated with 4.25-, 3.61-, and 1.67- fold increased incidence of childhood epilepsy. A 10 cm increase in umbilical cord length was associated with a 15% decrease in the incidence of epilepsy (adjusted OR 0.85, 95% CI 0.78-0.94. However, the above reproductive factors accounted for less than 2% of total incidence, whereas maternal epilepsy proved to be the highest risk factor. CONCLUSIONS: Perinatal and reproductive factors were shown to be minor risk factors of childhood epilepsy, implying that little can be done in obstetric care to prevent childhood epilepsy. Infertility treatment and umbilical cord length, independent of gestational age and congenital malformations, may be novel markers of childhood epilepsy.

  4. Promoting healthy lifestyles: Behavior modification and motivational interviewing in the treatment of childhood obesity.

    Childhood obesity has increased dramatically during the past two decades. The growing incidence of childhood obesity is alarming, given the significant short- and long-term health consequences associated with obesity and the strong tracking of obesity from childhood to adulthood. Lifestyle plays an important role in the development and maintenance of obesity. Behavior modification programs targeting eating, exercise, and diet behaviors continue to be the mainstay for treating obese children. Although family-based behavioral weight management programs have resulted in significant improvements in weight status, maintaining improvements in weight status continues to be a challenge, with many interventions resulting in considerable relapse. Motivational interviewing is one innovative approach, used alone or in conjunction with standard behavioral modification programs, which has been proposed to have the potential to enhance motivation for change and therefore improve long-term treatment outcomes for obese children. A broad literature search using two electronic databases, Medline and PsycINFO, to identify studies that used an intervention with a motivational interviewing component to modify diet and/or physical activity in the prevention or treatment of childhood obesity identified two studies that targeted weight as a primary outcome. The studies reviewed indicate that, although initial findings are encouraging, further research is needed to determine the effectiveness of motivational interviewing for prevention and treatment of childhood obesity. Concerted efforts are clearly needed to elucidate the mechanisms for maintenance of initial treatment gains, as well as the ultimate achievement of more ideal weight once formal treatment ceases.

  5. Subependymal giant cell astrocytomas in patients with tuberous sclerosis complex: considerations for surgical or pharmacotherapeutic intervention.

    Wheless, James W; Klimo, Paul

    2014-11-01

    Tuberous sclerosis complex is a genetic disorder caused by mutations in either the TSC1 or TSC2 gene that can result in the growth of hamartomas in multiple organ systems. Subependymal giant cell astrocytomas are slow-growing brain tumors associated primarily with tuberous sclerosis complex. They are usually located in the ventricles, often near the foramen of Monro, where they can cause an obstruction if they grow too large, leading to increased intracranial pressure. Surgery to remove a tumor has been the mainstay of treatment but can be associated with postoperative morbidity and mortality. Not all tumors and/or patients are suitable for surgery. The recent development of mammalian target of rapamycin inhibitors that target the pathway affected by TSC1/TSC2 mutations offers a novel pharmacotherapeutic option for these patients. We review the timing and use of surgery versus pharmacotherapy for the treatment of subependymal giant cell astrocytoma in patients with tuberous sclerosis complex.

    OBJECTIVE Diffuse astrocytomas (DAs) have a high recurrence rate due to diffuse infiltration into the brain and spinal cord. Micro RNAs (miRNAs) are small noncoding RNAs that regulate gene expression by binding to complementary sequences of target messenger RNA (mRNA). It has been reported that miRNA-22 (miR-22) is involved in the invasion of some cancer cell lines. The aim of this study was to identify the biological effects of miR-22 in regard to the invasion of human DAs. METHODS The authors evaluated whether the level of miR-22 is elevated in human spinal DAs by using miRNA chips. Next, the role of miR-22 in 1321N1 human astrocytoma cells was investigated. Finally, to elucidate whether miR-22 promotes invasion by astrocytoma cells in vivo, the authors transplanted miR-22 overexpressed astrocytoma cells into mouse thoracic spinal cord. RESULTS The miR-22 significantly upregulated the invasion capacity of 1321N1 cells. Computational in silico analysis predicted that tissue inhibitor of matrix metalloproteinase-2 (TIMP2) is a target gene of miR-22. This was confirmed by quantitative reverse transcription polymerase chain reaction and Western blotting, which showed that miR-22 inhibited TIMP2 mRNA and protein expression, respectively. Luciferase reporter assays demonstrated that miR-22 directly bound the 3'-untranslated regions of TIMP2. The authors further showed that miR-22 promoted invasiveness in 1321N1 astrocytoma cells when transplanted into mouse spinal cord. CONCLUSIONS These data suggest that miR-22 acts to regulate invasion of 1321N1 astrocytoma cells by targeting TIMP2 expression. Additional studies with more cases and cell lines are required to elucidate the findings of this study for a novel treatment target for spinal DAs.

    Posttraumatic stress disorder (PTSD) is highly prevalent in adult survivors of childhood sexual and/or physical abuse. However, intervention studies focusing on this group of patients are underrepresented in earlier meta-analyses on the efficacy of PTSD treatments. The current meta-analysis exclusively focused on studies evaluating the efficacy of psychological interventions for PTSD in adult survivors of childhood abuse. Sixteen randomized controlled trials meeting inclusion criteria could be identified that were subdivided into trauma-focused cognitive behavior therapy (CBT), non-trauma-focused CBT, eye movement desensitization and reprocessing, and other treatments (interpersonal, emotion-focused). Results showed that psychological interventions are efficacious for PTSD in adult survivors of childhood abuse, with an aggregated uncontrolled effect size of g=1.24 (pre- vs. post-treatment), and aggregated controlled effect sizes of g=0.72 (post-treatment, comparison to waitlist control conditions) and g=0.50 (post-treatment, comparison with TAU/placebo control conditions), respectively. Effect sizes remained stable at follow-up. As the heterogeneity between studies was large, we examined the influence of two a priori specified moderator variables on treatment efficacy. Results showed that trauma-focused treatments were more efficacious than non-trauma-focused interventions, and that treatments including individual sessions yielded larger effect sizes than pure group treatments. As a whole, the findings are in line with earlier meta-analyses showing that the best effects can be achieved with individual trauma-focused treatments.

  11. Progesterone Receptor Subcellular Localization and Gene Expression Profile in Human Astrocytoma Cells Are Modified by Progesterone

    Full Text Available Intracellular progesterone receptor (PR has been identified in human astrocytomas, the most common and aggressive primary brain tumors in humans. It has been reported that PR cell distribution affects their transcriptional activity and turnover. In this work we studied by immunofluorescence the effects of estradiol and progesterone on the subcellular localization of PR in a grade III human astrocytoma derived cell line (U373. We observed that total PR was mainly distributed in the cytoplasm without hormonal treatment. Estradiol (10 nM increased PR presence in the cytoplasm of U373 cells, whereas progesterone (10 nM and RU486 (PR antagonist, 1 μM blocked this effect. To investigate the role of PR activity in the regulation of gene expression pattern of U373 cells, we evaluated by microarray analysis the profile of genes regulated by progesterone, RU486, or both steroids. We found different genes regulated by steroid treatments that encode for proteins involved in metabolism, transport, cell cycle, proliferation, metastasis, apoptosis, processing of nucleic acids and proteins, adhesion, pathogenesis, immune response, cytoskeleton, and membrane receptors. We determined that 30 genes were regulated by progesterone, 41 genes by RU486 alone, and 13 genes by the cotreatment of progesterone+RU486, suggesting that there are many genes regulated by intracellular PR or through other signaling pathways modulated by progesterone. All these data suggest that PR distribution and activity should modify astrocytomas growth.

  12. Modeling social transmission dynamics of unhealthy behaviors for evaluating prevention and treatment interventions on childhood obesity.

    Directory of Open Access Journals (Sweden)

    Leah M Frerichs

    Full Text Available Research evidence indicates that obesity has spread through social networks, but lever points for interventions based on overlapping networks are not well studied. The objective of our research was to construct and parameterize a system dynamics model of the social transmission of behaviors through adult and youth influence in order to explore hypotheses and identify plausible lever points for future childhood obesity intervention research. Our objectives were: (1 to assess the sensitivity of childhood overweight and obesity prevalence to peer and adult social transmission rates, and (2 to test the effect of combinations of prevention and treatment interventions on the prevalence of childhood overweight and obesity. To address the first objective, we conducted two-way sensitivity analyses of adult-to-child and child-to-child social transmission in relation to childhood overweight and obesity prevalence. For the second objective, alternative combinations of prevention and treatment interventions were tested by varying model parameters of social transmission and weight loss behavior rates. Our results indicated child overweight and obesity prevalence might be slightly more sensitive to the same relative change in the adult-to-child compared to the child-to-child social transmission rate. In our simulations, alternatives with treatment alone, compared to prevention alone, reduced the prevalence of childhood overweight and obesity more after 10 years (1.2-1.8% and 0.2-1.0% greater reduction when targeted at children and adults respectively. Also, as the impact of adult interventions on children was increased, the rank of six alternatives that included adults became better (i.e., resulting in lower 10 year childhood overweight and obesity prevalence than alternatives that only involved children. The findings imply that social transmission dynamics should be considered when designing both prevention and treatment intervention approaches. Finally

    Childhood idiopathic language deterioration is a rare condition in which children lose previously gained language skills. In some children this language deterioration occurs in association with behavioral seizures or EEG epileptiform activity. The effectiveness of antiepileptic drugs in this patient population is not known. Here we retrospectively reviewed records of 57 children with childhood idiopathic language deterioration associated with seizures or epileptiform activity on their EEG who received valproate for the purpose of treating their language impairment. In 22 of the children improvement in language skills was observed. In two children language returned to normal while in the other 20 the improvement was modest. Children who responded to valproate had an earlier age of onset of the aphasia than children who were nonresponders. Seizure type, EEG findings, developmental status, and presence or absence of a frequency-modulated auditory evoked potential were not related to response. This study demonstrates that valproate can be helpful in improving language function in some children with idiopathic language deterioration associated with seizures or epileptiform activity on the EEG.

    Cytogenetic analysis by direct and/or in vitro preparations was performed on 34 malignant astrocytomas. Thirty tumors showed near-diploid chromosome numbers, whereas, tritetraploid chromosome complements were present in four tumors. The most frequent chromosomal changes implied numerical deviations by a gain of chromosomes #7, #19, and #20, and by losses of #10, #22, and Y. Structural rearrangements were present in stem- or side lines of 24 tumors. Although no common chromosomal rearrangement seems to exist among those tumors, chromosomes #1, #6, #7, and #9 were predominantly involved. Polysomy and structural rearrangements of chromosome #7 could be related to the overexpression of epidermal growth factor gene, previously observed in some malignant gliomas.

    The ability to accurately distinguish remaining or recurrent high-grade astrocytoma from necrosis or edema following treatment is essential to optimal patient management. Thallium 201 planar gamma-camera imaging has been shown to be helpful in detecting recurrent high-grade astrocytoma; however, due to tissue heterogeneity adjacent to and within tumor, the cellular specificity and quantification of 201Tl uptake are largely unknown. In order to determine which tissues are responsible for the radioisotope uptake, microautoradiographic techniques were used to examine multiple tissue sections from five patients with high-grade astrocytoma. Each patient received 5 mCi of 201Tl i.v. 1 h prior to tumor removal. Additionally, all patients received computerized tomographic and 201Tl planar gamma-camera scans prior to surgery. Following surgery, the excised tissue specimens were tentatively classified by gross pathological examination and then immediately processed for dry mount autoradiography; grain density was determined over regions containing tumor, adjacent and uninvolved brain tissue, necrotic tissue, and background. Highly significant differences were found in grain densities (201Tl uptake) between tumor and uninvolved brain tissue, as well as between uninvolved brain tissue and necrotic tissue; there was no significant difference between background grain density and that in necrotic tissue. Mean grain densities (grains/cm2 +/- 1 SD) across patients were: tumor, 102 +/- 23; adjacent, uninvolved brain tissue, 29 +/- 11; necrotic tissue, 6.2 +/- 1.1; and background, 7.0 +/- 4.1. We conclude that the ability of 201Tl to selectively image high-grade astrocytoma is due to its preferential uptake into tumor cells.

    Background: To evaluate the safety and efficacy of proton radiation therapy (PRT) for intracranial low-grade astrocytomas, the authors analyzed the first 27 pediatric patients treated at Loma Linda University Medical Center (LLUMC). Patients and Method: Between September 1991 and August 1997, 27 patients (13 female, 14 male) underwent fractionated proton radiation therapy for progressive or recurrent low-grade astrocytoma. Age at time of treatment ranged from 2 to 18 years (mean: 8.7 years). Tumors were located centrally (diencephatic) in 15 patients, in the cerebral and cerebellar hemispheres in seven patients, and in the brainstem in five patients. 25/27 patients (92%) were treated for progressive, unresectable, or residual disease following subtotal resection. Tissue diagnosis was available in 23/27 patients (85%). Four patients with optic pathway tumors were treated without histologic confirmation. Target doses between 50.4 and 63.0 CGE (cobalt gray equivalent, mean: 55.2 CGE) were prescribed at 1.8 CGE per fraction, five treatments per week. Results: At a mean follow-up period of 3.3 years (0.6-6.8 years), 6/27 patients experienced local failure (all located within the irradiated field), and 4/27 patients had died. By anatomic site these data translated into rates of local control and survival of 87% (13/15 patients) and 93% (14/15 patients) for central tumors, 71% (5/7 patients) and 86% (6/7 patients) for hemispheric tumors, and 60% (3/5 patients) and 60% (3/5 patients) for tumors located in the brainstem. Proton radiation therapy was generally well tolerated. All children with local control maintained their performance status. One child with associated neurofibromatosis, Type 1, developed Moyamoya disease. All six patients with optic pathway tumors and useful vision maintained or improved their visual status. Conclusions: This report on pediatric low-grade astrocytomas confirms proton radiation therapy as a safe and efficacious 3-D conformal treatment

    2013-02-01

    Constipation in children is defined on the basis of several clusters of symptoms, and these symptoms are likely to persist into adulthood. The aim of this review article is to summarize the current literature on the use of dietary fiber and whole grains as treatments for childhood constipation. Current recommendations for fiber intake in children vary substantially among organizations, suggesting that the function of fiber in children is not fully understood. Additionally, no formal definition of "whole grain" exists, which further complicates the interpretation of the literature. Few randomized controlled trials have examined the effect of dietary fiber supplementation in children with constipation. Currently, no randomized controlled trials have investigated the efficacy of whole grains in treating childhood constipation. This is an area that warrants further attention. Increasing the intake of dietary fiber and/or whole grain has the potential to relieve childhood constipation; however, additional randomized controlled trials are necessary to make a formal recommendation.

    2006-06-01

    Full Text Available Abstract Background Hypophosphatasia (HP is an inborn error of bone metabolism characterized by a genetic defect in the gene encoding the tissue-nonspecific alkaline phosphatase (TNSALP. There is a lack of knowledge as to how the variability and clinical severity of the HP phenotype (especially pain and walking impairment are related to metabolic disturbances or impairments, subsequent to the molecular defect. Methods We analyzed the changes in clinical symptoms and the prostaglandin (PG metabolism in response to treatment with non-steroidal anti-inflammatory drugs (NSAIDs in six children affected by childhood HP. In addition, by exposing HP fibroblasts to pyridoxal phosphate and/or calcium pyrophosphate in vitro, we analyzed whether the alterations in PG levels are sequelae related to the metabolic defect. Results Childhood HP patients, who often complain about pain in the lower limbs without evident fractures, have systemic hyperprostaglandinism. Symptomatic anti-inflammatory treatment with NSAIDs significantly improved pain-associated physical impairment. Calcium pyrophosphate, but not pyridoxal phosphate, induced cyclooxygenase-2 (COX-2 gene expression and PG production in HP and normal fibroblasts in vitro. Conclusion Clinical features of childhood HP related to pain in the lower legs may be, at least in part, sequelae related to elevated PG levels, secondary to the primary metabolic defect. Consequently, NSAID treatment does improve the clinical features of childhood HP.

    Material and Methods: Studies on the use of radiation therapy in children with low-grade glioma were systematically reviewed for data on radiotherapy-induced side effects on brain parenchyma, endocrine dysfunction, growth retardation, neurocognitive dysfunction, vasculopathy, and secondary neoplasms. Results: Data on late effects are scarce and heterogeneous. Past reports included only retrospective series from the 1930s to present days, a time during which treatment policies and radiation techniques widely varied and considerably changed in recent years. Often, considerable uncertainty existed regarding pretreatment health status and radiotherapy-related factors (e.g., total dose, dose per fraction, treatment fields). In spite of these shortcomings and often conflicting observations, it appears that especially younger children and children with neurofibromatosis (NF) are at risk of endocrinopathies in terms of growth retardation and developmental abnormalities, as well as neurocognitive dysfunction expressed as problems in the psychosocial environment such as in education and occupation. However, both observations may be attributed to the higher proportion of NF in the very young who frequently develop large tumors spreading along the entire supratentorial midline. The risk of radiation-induced disturbances in visual function is low (no case reported). Young children with NF appear to have an increased risk of vasculopathies. 33 cases of moyamoya disease were found (preferably in the very young), 18 of whom were NF-positive. Other cerebrovascular accidents (24 cases, of whom 14 were NF-positive) and secondary neoplasms (15 cases, of whom only five occurred in field - four were high-grade astrocytomas) are a rare condition. The latter cannot be distinguished from late relapses with malignant transformation. Modern treatment techniques appear to reduce the risk of radiation-induced late effects. Conclusions: More studies and clear definitions of clinical endpoints

    2014-01-01

    Background The prevalence of childhood obesity, which has seen a rapid increase over the last decade, is now considered a major public health problem. Current treatment options are based on the two important frameworks of school- and family-based interventions; however, most research has yet to compare the two frameworks in the treatment of childhood obesity. The objective of this review is to compare the effectiveness of school-based intervention with family-based intervention in the treatment of childhood obesity. Methods Databases such as Medline, Pub med, CINAHL, and Science Direct were used to execute the search for primary research papers according to inclusion criteria. The review included a randomised controlled trial and quasi-randomised controlled trials based on family- and school-based intervention frameworks on the treatment of childhood obesity. Results The review identified 1231 articles of which 13 met the criteria. Out of the thirteen studies, eight were family-based interventions (n = 8) and five were school-based interventions (n = 5) with total participants (n = 2067). The participants were aged between 6 and 17 with the study duration ranging between one month and three years. Family-based interventions demonstrated effectiveness for children under the age of twelve and school-based intervention was most effective for those aged between 12 and 17 with differences for both long-term and short-term results. Conclusions The evidence shows that family- and school-based interventions have a considerable effect on treating childhood obesity. However, the effectiveness of the interventional frameworks depends on factors such as age, short- or long-term outcome, and methodological quality of the trials. Further research studies are required to determine the effectiveness of family- and school-based interventions using primary outcomes such as weight, BMI, percentage overweight and waist circumference in addition to the aforementioned

  13. Transcriptional analysis of aggressiveness and heterogeneity across grades of astrocytomas.

    Directory of Open Access Journals (Sweden)

    Chunjing Wang

    Full Text Available Astrocytoma is the most common glioma, accounting for half of all primary brain and spinal cord tumors. Late detection and the aggressive nature of high-grade astrocytomas contribute to high mortality rates. Though many studies identify candidate biomarkers using high-throughput transcriptomic profiling to stratify grades and subtypes, few have resulted in clinically actionable results. This shortcoming can be attributed, in part, to pronounced lab effects that reduce signature robustness and varied individual gene expression among patients with the same tumor. We addressed these issues by uniformly preprocessing publicly available transcriptomic data, comprising 306 tumor samples from three astrocytoma grades (Grade 2, 3, and 4 and 30 non-tumor samples (normal brain as control tissues. Utilizing Differential Rank Conservation (DIRAC, a network-based classification approach, we examined the global and individual patterns of network regulation across tumor grades. Additionally, we applied gene-based approaches to identify genes whose expression changed consistently with increasing tumor grade and evaluated their robustness across multiple studies using statistical sampling. Applying DIRAC, we observed a global trend of greater network dysregulation with increasing tumor aggressiveness. Individual networks displaying greater differences in regulation between adjacent grades play well-known roles in calcium/PKC, EGF, and transcription signaling. Interestingly, many of the 90 individual genes found to monotonically increase or decrease with astrocytoma grade are implicated in cancer-affected processes such as calcium signaling, mitochondrial metabolism, and apoptosis. The fact that specific genes monotonically increase or decrease with increasing astrocytoma grade may reflect shared oncogenic mechanisms among phenotypically similar tumors. This work presents statistically significant results that enable better characterization of different human

  14. Characterization of a novel anti-cancer compound for astrocytomas.

    Directory of Open Access Journals (Sweden)

    Sang Y Lee

    Full Text Available The standard chemotherapy for brain tumors is temozolomide (TMZ, however, as many as 50% of brain tumors are reportedly TMZ resistant leaving patients without a chemotherapeutic option. We performed serial screening of TMZ resistant astrocytoma cell lines, and identified compounds that are cytotoxic to these cells. The most cytotoxic compound was an analog of thiobarbituric acid that we refer to as CC-I. There is a dose-dependent cytotoxic effect of CC-I in TMZ resistant astrocytoma cells. Cell death appears to occur via apoptosis. Following CC-I exposure, there was an increase in astrocytoma cells in the S and G2/M phases. In in vivo athymic (nu/nu nude mice subcutaneous and intracranial tumor models, CC-I completely inhibited tumor growth without liver or kidney toxicity. Molecular modeling and enzyme activity assays indicate that CC-I selectively inhibits topoisomerase IIα similar to other drugs in its class, but its cytotoxic effects on astrocytoma cells are stronger than these compounds. The cytotoxic effect of CC-I is stronger in cells expressing unmethylated O6-methylguanine methyltransferase (MGMT but is still toxic to cells with methylated MGMT. CC-I can also enhance the toxic effect of TMZ on astrocytoma when the two compounds are combined. In conclusion, we have identified a compound that is effective against astrocytomas including TMZ resistant astrocytomas in both cell culture and in vivo brain tumor models. The enhanced cytotoxicity of CC-I and the safety profile of this family of drugs could provide an interesting tool for broader evaluation against brain tumors.

    James, C.D.; Carlbom, E.; Nordenskjold, M.; Collins, V.P.; Cavenee, W.K. (Ludwig Institute for Cancer Research, Montreal (Canada))

    1989-04-01

    Allelic combinations at seven loci on human chromosome 17 defined by restriction fragment length polymorphisms were determined in tumor and normal tissues from 35 patients with gliomas. Loss of constitutional heterozygosity at one or more of these loci was observed in 8 of the 24 tumors displaying astrocytic differentiation and in the single primitive neuroectodermal tumor examined. The astrocytomas showing these losses included examples of each adult malignancy grade of the disease, including glioblastoma (malignancy grade IV), and seven of them demonstrated concurrent maintenance of heterozygosity for at least one chromosome 17 locus. Determination of allele dosage together with the genotypic data indicated that the tumor chromosomes 17 were derived by mitotic recombination in 7 of the 9 cases with shared homozygosity of the region 17p11.2-ptr in all cases. In contrast, tumors of oligodendrocytic, ependymal, or mixed cellular differentiation did not exhibit loss of alleles at any of the loci examined. These data suggest that the somatic attainment of homozygosity for loci on chromosome 17p is frequently associated with the oncogenesis of central nervous system tumors, particularly those showing solely astrocytic differentiation, and that mitotic recombination mapping is a useful approach towards the subregional localization of a locus whose rearrangement is involved in this disease.

  18. Application of Research Domain Criteria to childhood and adolescent impulsive and addictive disorders: Implications for treatment.

    2016-11-09

    The Research Domain Criteria (RDoC) initiative provides a large-scale, dimensional framework for the integration of research findings across traditional diagnoses, with the long-term aim of improving existing psychiatric treatments. A neurodevelopmental perspective is essential to this endeavor. However, few papers synthesizing research findings across childhood and adolescent disorders exist. Here, we discuss how the RDoC framework may be applied to the study of childhood and adolescent impulsive and addictive disorders in order to improve neurodevelopmental understanding and to enhance treatment development. Given the large scope of RDoC, we focus on a single construct highly relevant to addictive and impulsive disorders - initial responsiveness to reward attainment. Findings from genetic, molecular, neuroimaging and other translational research methodologies are highlighted.

    Kelly, Katherine Patterson; Ganong, Lawrence

    2011-03-01

    Few researchers have studied how parents from diverse family structures cope with childhood chronic illness. We designed this study to discern the childhood cancer treatment decision-making (TDM) process in these families. Using grounded theory, we interviewed 15 custodial parents, nonresidential parents, and stepparents who had previously made a major treatment decision for their children with cancer. "Moving to place" was the central psychosocial process by which parents negotiated involvement in TDM. Parents moved toward or were moved away from involvement based on parent position in the family (custodial, nonresidential, and stepparent), prediagnosis family dynamics, and time since diagnosis. Parents used the actions of stepping up, stepping back, being pushed, and stepping away to respond to the need for TDM. Parents faced additional stressors because of their family situations, which affected the TDM process. Findings from this study provide important insight into diverse families and their unique parental TDM experiences.

    The process of group therapy with five aggressive young boys, utilizing bibliotherapy as its primary mode of intervention, was investigated and is illustrated in this paper. The rationale for using affective bibliotherapy in a group context is given, the content of the program is described, and the process is fully displayed. The effectiveness of the treatment was studied in a single-subject design, comparing treatment children with their matched counterparts. Results pointed to reduced aggression of all the five treatment students, compared with no change in the control children, by self- and teacher report. In addition, results based on an analysis of transcripts showed increased constructive behavior in group for all participants. Although these results should not be generalized, they suggest an interesting line of research for future investigation.

  1. Promising medical treatment for childhood psycho-cognitive problems

    2010-01-01

    Subclinical electroencephalogram discharges in children with psycho-cognitive problems are not uncommon. However, the clinical importance and relationship to cognitive deficits, as well as indications for medical treatment, are not well understood. Transient cognitive impairment, which accompanies electroencephalogram discharges, could negatively influence cognitive abilities over time. Studies have suggested that treatment with antiepileptic drugs normalizes electroencephalogram results, thereby preventing electrical paroxysmal discharges that could be harmful to the developing brain. Physicians should attempt to differentiate between corresponding factors, such as subtle seizures, nature of underlying etiology, stable cognitive deficits,seizure-inducing effects, and potential side effects of antiepileptic drugs prior to initiation of medical treatment for definitive diagnosis of transient cognitive impairment and its consequences. Therefore,appropriate criteria for patient selection and proper guidelines for medical therapy, should be addressed in future studies.

    2017-04-01

    Endocrine complications are frequently observed in childhood cancer survivors (CCS). One of two CCS will experience at least one endocrine complication during the course of his/her lifespan, most commonly as a late-effect of cancer treatments, especially radiotherapy and alkylating agent chemotherapy. Endocrine late-effects include impairments of the hypothalamus/pituitary, thyroid and gonads, as well as decreased bone mineral density and metabolic derangements leading to obesity and/or diabetes mellitus. A systematic approach where CCS are screened for endocrine late-effects based on their cancer history and treatment exposures may improve health outcomes by allowing the early diagnosis and treatment of these complications.

    2012-12-01

    World Health Organization (WHO) grade I astrocytomas include pilocytic astrocytoma (PA) and subependymal giant cell astrocytoma (SEGA). As technologies in pharmacologic neo-adjuvant therapy continue to progress and as molecular characteristics are progressively recognized as potential markers of both clinically significant tumor subtypes and response to therapy, interest in the biology of these tumors has surged. An updated review of the current knowledge of the molecular biology of these tumors is needed. We conducted a Medline search to identify published literature discussing the molecular biology of grade I astrocytomas. We then summarized this literature and discuss it in a logical framework through which the complex biology of these tumors can be clearly understood. A comprehensive review of the molecular biology of WHO grade I astrocytomas is presented. The past several years have seen rapid progress in the level of understanding of PA in particular, but the molecular literature regarding both PA and SEGA remains nebulous, ambiguous, and occasionally contradictory. In this review we provide a comprehensive discussion of the current understanding of the chromosomal, genomic, and epigenomic features of both PA and SEGA and provide a logical framework in which these data can be more readily understood.

    Pilocytic astrocytoma usually has a classic imaging manifestation of a solitary, cyst-like mass with a strong contrast-enhancing mural nodule. There is only one published report so far of multiple solid and cyst type pilocytic astrocytomas in the cerebellum in neurofibromatosis type 1 (NF1) patient from the United States in 2007. We report a case of pilocytic astrocytoma presenting with only solid, multiple pilocytic astrocytomas in the cerebellum in NF1 patient.

    All forms of cutaneous T-cell lymphoma are rare in childhood. We describe an 8-year-old boy with plaque-stage mycosis fungoides stage IIA whose cutaneous eruption had been present for 5 years. Histologic examination revealed the presence of a granulomatous infiltrate together with atypical lymphocytes within the dermis. The child had an excellent response to combination psoralen-UVA (PUVA) with interferon-alpha 2a treatment and is currently in remission.

    In the general population it is evident that parent feeding practices can directly shape a child's life long dietary intake. Young children undergoing childhood cancer treatment may experience feeding difficulties and limited food intake, due to the inherent side effects of their anti-cancer treatment. What is not clear is how these treatment side effects are influencing the parent-child feeding relationship during anti-cancer treatment. This retrospective qualitative study collected telephone based interview data from 38 parents of childhood cancer patients who had recently completed cancer treatment (child's mean age: 6.98 years). Parents described a range of treatment side effects that impacted on their child's ability to eat, often resulting in weight loss. Sixty-one percent of parents (n = 23) reported high levels of stress in regard to their child's eating and weight loss during treatment. Parents reported stress, feelings of helplessness, and conflict and/or tension between parent and the child during feeding/eating interactions. Parents described using both positive and negative feeding practices, such as: pressuring their child to eat, threatening the insertion of a nasogastric feeding tube, encouraging the child to eat and providing home cooked meals in hospital. Results indicated that parent stress may lead to the use of coping strategies such as positive or negative feeding practices to entice their child to eat during cancer treatment. Future research is recommended to determine the implication of parent feeding practice on the long term diet quality and food preferences of childhood cancer survivors.

    2005-06-01

    Background and purpose: only 3% of all malignant intranasal tumors are esthesioneuroblastomas (ENB) and only 20% of these rare neuroectodermal tumors are diagnosed up to 20 years of age. Radiotherapy and surgery are established treatment modalities for these patients, but the role of chemotherapy, especially in a multimodal approach, is not well defined. To investigate the influence of radio- and chemotherapy, the treatment and course of the disease in children and adolescents with ENB were analyzed retrospectively. Patients and methods: 19 unselected patients (nine male and ten female) diagnosed with ENB {<=} 20 years of age were included in this analysis. Median age at diagnosis was 14.0 years (range, 5-20 years). The tumors were Kadish stage B in 4/19 patients and stage C in 15/19 patients. 17 patients underwent surgery, either without further therapy (n = 4), followed by radiotherapy (n = 1) or as part of multimodal regimens (n = 12). Two patients received radio- and chemotherapy without surgery. Complete resection (RO) was achieved in 15 out of 17 patients with surgery including all five patients with preoperative chemotherapy due to unresectable primary at diagnosis. Results: the 5-year overall survival (OS) for the whole group was 73% {+-} 12% and the 5-year event-free survival (EFS) 55% {+-} 13%. None of the four patients with stage B experienced tumor progression so far, whereas seven out of 15 patients with stage C did (5-year EFS 47% {+-} 14%; not significant). Patients with Kadish stage C and multimodal treatment strategies combing surgery, chemo- and radiotherapy had a significantly better outcome than patients with stage C and less than three treatment modalities (65% {+-} 17% vs. 20% {+-} 18%; p = 0.02). Conclusion: these data indicate a benefit of multimodal treatment regimens combining surgery, chemo- and radiotherapy for pediatric patients with ENB Kadish stage C. Chemotherapy appears to improve resectability, EFS, and OS. Radiotherapy is an

    The ways in which sleep can affect epilepsy, and epilepsy can influence sleep and wakefulness, are described. Different forms of sleep disturbance have been reported in patients with epilepsy, depending on the type of seizure disorder. Confusions between epilepsy and non-epileptic parasomnias can be a particular diagnostic problem but they can be avoided. Untreated sleep disturbance is likely to have harmful psychological, physical and family effects. Screening for sleep disturbance should be routine, and leading, if indicated, to precise diagnosis of the underlying sleep disorder on which choice of advice and treatment depends.

    With improvements in survival among individuals diagnosed and treated for cancer there is an increasing recognition of the risk of long-term adverse effects of therapy. Second neoplasms represent one of the more serious late effects of treatment and are associated with a substantial level of morbidity and mortality. Survivors of childhood cancers, because of their potential longevity, are at particular risk for this adverse outcome. The Childhood Cancer Survivor Study is a large cohort consisting of adult survivors of childhood cancer diagnosed and treated between 1970 and 1986. The CCSS has provided important data to quantify radiation-associated risk for subsequent cancers including neoplasms of the breast, thyroid and central nervous system. (orig.)

    Objective The aim of this study was to investigate the prevalence of overweight/obesity among parents of children entering childhood obesity treatment and to evaluate changes in the parents’ weight statuses during their child’s treatment. Methods The study included parents of 1,125 children and adolescents aged 3–22 years, who were enrolled in a multidisciplinary childhood obesity treatment program. At baseline, weight and height of the parents were obtained by self-reported information and parental body mass index (BMI) was calculated. Weight and height of the children were measured in the clinic and BMI standard deviation scores were calculated. Furthermore, anthropometric data from parents of 664 children were obtained by telephone interview after a mean of 2.5 years of treatment (ranging 16 days to 7 years), and changes in parental BMI were analyzed. Results Data on changes in BMI were available in 606 mothers and 479 fathers. At baseline, the median BMI of the mothers was 28.1 kg/m2 (range: 16.9–66.6), and the median BMI of the fathers was 28.9 kg/m2 (range: 17.2–48.1). Seventy percent of the mothers and 80% of the fathers were overweight or obese at the time of their child’s treatment initiation. Both the mothers and fathers lost weight during their child’s treatment with a mean decrease in BMI in the mothers of 0.5 (95% CI: 0.2–0.8, p = 0.0006) and in the fathers of 0.4 (95% CI: 0.2–0.6, p = 0.0007). Of the overweight/obese parents, 60% of the mothers and 58% of the fathers lost weight during their child’s treatment. Conclusion There is a high prevalence of overweight/obesity among parents of children entering childhood obesity treatment. Family-based childhood obesity treatment with a focus on the child has a positive effect on parental BMI with both mothers and fathers losing weight.

    Thirty-one children under the age of 15 years with verified medulloblastoma were treated at Addenbrookes Hospital from 1940 to 1976. In addition to surgical treatment, all received high dose irradiation to the whole neuraxis. Nine were still alive in 1979, of whom eight were examined. All these patients showed some residual problems, but five were leading active lives and had only minor physical disability. There was evidence of disturbance in growth, with shortening of the spine in relation to the limbs, in all the children. The height centile was lower than expected from parental height in four and one was severely dwarfed. Growth hormone secretion in response to exercise was, however, normal in five of six patients tested. Three children also showed failure of growth of the jaw sufficiently severe to be a cosmetic problem. Frank mental retardation was present in three children. A raised resting TSH level was found in two children, one of whom had a multinodular goiter. Of the three children with severe problems, two had been treated when under two years of age. Long-term follow-up of children who survive medulloblastoma is clearly necessary and consideration should perhaps be given to revision of current treatment regimes in very young children.

    With the development of autism therapy, acupuncture, an alternative therapy, is becoming popular for autism children. There have been many papers found about the treatment of autism by acupuncture therapy so far. In the present review, the authors briefly introduce the theoretical basis of autism in traditional Chinese medicine and the application history, and sum up the acupoint prescriptions, effectiveness as well as the assessment tools of acupuncture therapy for autism. It is suggested that acupuncture therapy is a relatively effective therapy for autism children. It has positive roles in improving autistic syndromes without any side-effects, especially in improving language development, daily-life self-care, and social communications. The underlying mechanism of this therapy may be explained by acupuncture intervention induced favorable changes of neurochemistry, cerebral blood flow, and cerebral functional activities. Although there are lots of questions to be answered about acupuncture treatment of autism, we hold a positive opinion that this therapy might be a green effective therapy for autistic children in the future.

    Full Text Available Abstract Background With improved childhood cancer cure rate, long term sequelae are becoming an important factor of quality of life. Signs of cardiovascular disease are frequently found in long term survivors of cancer. Cardiac damage may be related to irradiation and chemotherapy. We have evaluated simultaneous influence of a series of independent variables on the late cardiac damage in childhood cancer survivors in Slovenia and identified groups at the highest risk. Methods 211 long-term survivors of different childhood cancers, at least five years after treatment were included in the study. The evaluation included history, physical examination, electrocardiograpy, exercise testing and echocardiograpy. For analysis of risk factors, beside univariate analysis, multivariate classification tree analysis statistical method was used. Results and Conclusion Patients treated latest, from 1989–98 are at highest risk for any injury to the heart (73%. Among those treated earlier are at the highest risk those with Hodgkin's disease treated with irradiation above 30 Gy and those treated for sarcoma. Among specific forms of injury, patients treated with radiation to the heart area are at highest risk of injury to the valves. Patients treated with large doses of anthracyclines or concomitantly with anthracyclines and alkylating agents are at highest risk of systolic function defect and enlarged heart chambers. Those treated with anthracyclines are at highest risk of diastolic function defect. The time period of the patient's treatment is emerged as an important risk factor for injury of the heart.

    We performed a retrospective analysis of 394 patients who were treated for active tuberculosis (TB) at our hospital from 1976 to 1997. We had started early BCG vaccination campaign in Osaka Prefecture from 1995 and the coverage of BCG vaccination in infants rose up to about 90%. From that experience, we studied the current situations and measures on prevention and treatment of childhood tuberculosis. Pulmonary TB in children is successfully treated with 6-month standard short-course chemotherapy using isoniazid, rifampin, and pyrazinamide daily for 2 months, followed by isoniazid and rifampin daily for 4 months. Prognosis of childhood tuberculous meningitis (TBM) is poor, early diagnosis and prevention of TBM is important. In order to promote TB control and eliminate childhood TB, especially in infants, the following is necessary; 1) early detection and treatment of adult TB patients, source of infection, 2) prompt and appropriate contact examination and chemoprophylaxis, 3) BCG vaccination during early infancy, 4) protection from MDR-TB are most important.

    Full Text Available Introduction. Femoral neck fractures in children and adolescents are rare. However, their complications are frequent - avascular necrosis, femoral neck pseudoarthrosis, premature physeal closure with consequent growth disturbance and coxa vara deformity. Case Outline. A 9.5­year­old boy was injured in a car accident, and femoral neck fracture was diagnosed. Prior to admission at our hospital he was surgically treated several times. He was admitted at our hospital eight months following the accident. On the X­ray transcervical pseudoarthrosis of the femoral neck was found, as well as coxa vara deformity and metaphyseal avascular necrosis. He was operated at our hospital; all previously placed ostefixation material was removed, valgus osteotomy of 30 degrees was done as well as additional local osteoplasty using the commercial osteoindactive agent (Osteovit®. Postoperatively, we applied skin traction, bed rest and physical therapy. At the final follow­up, the patient was recovered completely. He is now painless, the legs are of equal length, range of movements in the left hip is full, life activity is normal. The X­ray shows that the femoral neck pseudoarthrosis is fully healed. Conclusion. This case is presented in order to encourage other colleagues to challenge the problematic situation such as this one. Also, we would like to remind them what one should think about and what should be taken into consideration in the primary treatment of femoral neck fractures in children. Valgus femoral osteotomy, as a part of the primary treatment of femoral neck fracture in children (identically as in the adults can prevent the occurrence of femoral neck pseudoarthrosis.

    All inflammatory changes in the vessel wall are defined as vasculitis. Pediatric vasculitis may present with different clinical findings. Although Henoch-Schönlein purpura which is the most common pediatric vasculitis generally recovers spontaneously, it should be monitorized closely because of the risk of renal failure. Although Kawasaki disease is easy to diagnose with its classical findings, the diagnosis may be delayed in case of incomplete Kawasaki disease. Kawasaki disease should be considered especially in infants in case of prolonged fever even if the criteria are not fully met and intravenous immunoglobulin treatment should be administered without delay in order to prevent development of coronary artery aneurism. Reaction at the site of administration of Bacillus Calmette-Guerin (BCG) vaccine may be observed as commonly as cervical lymphadenopathy in Kawasaki disease and may be used as a valuable finding in suspicious cases. Although anti-neutrophil cytoplasmic antibody-associated vasculitides are rare in children, renal involvement is more common and progression is more severe compared to adults. Hence, efficient and aggressive treatment is required. Takayasu's arteritis is observed commonly in young adult women and rarely in adolescent girls. Therefore, a careful physical examination and blood pressure measurement should be performed in addition to a detailed history in daily practice. In children with unexplained neurological findings, cerebral vasculitis should be considered in the absence of other systemic vasculitides and necessary radiological investigations should be performed in this regard. This review will provide an insight into the understanding of pediatric vasculitis, current diagnostic approaches and prognosis by the aid of new studies.

    A three-year-old boy presented with 2 months of worsening skin lesions characterized by multiple clear vesicles and bullae. The histopathological and immunohistochemical examinations revealed changes consistent with linear IgA bullous dermatosis of childhood. Treatment with dapsone and prednisolone resulted in gradual clinical improvement. However, within a week of therapy he presented with diabetic ketoacidosis, the onset of type I diabetes mellitus. Since then, keeping this child asymptomatic has been a challenge. This case emphasizes the importance of close monitoring of patients taking systemic corticosteroids; the coexistence of other immune mediated conditions may influence the success of treatment.

    Purpose of review To provide an update on the genes associated with Cushing’s syndrome in children, as well as to familiarize the clinician with recent treatment guidelines and outcome data for children with Cushing’s syndrome. Recent findings The list of genes associated with Cushing’s syndrome continues to grow. In addition, treatment for childhood Cushing’s syndrome is evolving. As long-term follow-up data on children becomes available, clinicians need to be aware of the issues that require attention. Summary Knowledge of the specific genetic causes of Cushing’s syndrome has potential implications for treatment, surveillance, and counseling. Advances in surgical technique, radiation modalities, and medical therapies offer the potential for additional treatment options in Cushing’s syndrome. Early identification and management of post-treatment morbidities in children treated for Cushing’s syndrome is crucial in order to optimize care. PMID:25517021

    Full Text Available Background: Childhood tuberculosis is a reflection of sputum-positive pulmonary tuberculosis and extent of transmission of tuberculosis in the community. Children suffer from serious form of tuberculosis and are more likely to die if not treated at proper time. Paediatricians are reluctant to refer them to Directly Observed Treatment- Short course (DOTS centres. Present study is conducted to know the clinical profile and treatment outcomes of childhood tuberculosis patients registered under Revised National Tuberculosis Control Program (RNTCP in Kottayam, Kerala. Methods: It was a record based cross-sectional study. Data was collected from RNTCP records from January to December 2009. Data was analysed using SPSS 16.0 and results were presented as proportions with 95% confidence limits. Chi-square test was used to find out the association. Results: The total number of paediatric tuberculosis cases was 155. There were 84 (55.6% males and 67(44.4% females. 66 (43.7% were less than 5 years of age. Out of 117 (77.5% pulmonary tuberculosis cases, 8 (0.06% were sputum smear-positive. Among extra-pulmonary TB cases, peripheral lymph node disease [25 (73.5%] was most common. The treatment completion rate was 90.7% with cure rate of 100% among sputum smear positive cases. Chi-square test showed significant association between age and treatment outcome (p-value <0.0001. Conclusions: Study showed that the RNTCP-DOTS is still the most effective strategy in treating childhood tuberculosis patients. Further studies are needed to assess the reasons for low proportion of smear positive and low TB meningitis cases.

    Full Text Available Progesterone (P4 promotes cell proliferation in several types of cancer, including brain tumors such as astrocytomas, the most common and aggressive primary intracerebral neoplasm in humans. In this work, we studied the effects of P4 and its intracellular receptor antagonist, RU486, on growth and infiltration of U373 cells derived from a human astrocytoma grade III, implanted in the motor cortex of adult male rats, using two treatment schemes. In the first one, fifteen days after cells implantation, rats were daily subcutaneously treated with vehicle (propylene glycol, 160 μL, P4 (1 mg, RU486 (5 mg, or P4 + RU486 (1 mg and 5 mg, resp. for 21 days. In the second one, treatments started 8 weeks after cells implantation and lasted for 14 days. In both schemes we found that P4 significantly increased the tumor area as compared with the rest of the treatments, whereas RU486 blocked P4 effects. All rats treated with P4 showed tumor infiltration, while 28.6% and 42.9% of the animals treated with RU486 and P4 + RU486, respectively, presented it. Our data suggest that P4 promotes growth and migration of human astrocytoma cells implanted in the motor cortex of the rat through the interaction with its intracellular receptor.

    The present study investigated the consistency of self-reports of childhood traumatic events in a sample of 50 patients with a borderline personality disorder (BPD) before and after 27 months of intensive treatment with schema focused therapy or transference focused psychotherapy. The mean number of reported sexual, physical and emotional traumatic events did not change following treatment. Test-retest correlations of the trauma-interview also indicated high stability of the total number of sexual, physical and emotional events reported. The majority of the patients, however, did no longer report at least one of the 33 listed events after psychotherapy, and the majority reported at least one event that they had not mentioned before the start of treatment. These findings were not related to type of treatment or changes in suppression, intrusions, avoidance of intrusions, dissociative symptoms, depressive symptoms, and borderline symptoms.

    Notch signaling pathway plays an integral role in determining cell fates in development. Growing evidence demonstrates that Notch signaling pathway has versatile effects in tumorigenesis depending on the tumor type, grade and stage. Notch signaling pathway is deregulated in some brain tumors. To examine the differential expression of Notch family members (Notch1, 2, 3, 4) in human astrocytomas and medulloblastomas, and to evaluate their roles in the development of both tumor types. Immunohistochemical staining and Western blot analysis were used to detect Notch1, 2, 3, 4 expression in tissue microarray and freshly resected tissue samples of normal brain, astrocytomas and medulloblastomas. Notch family members were not expressed or barely detectable in normal brain tissues. Notch1, 3, 4 were highly expressed but Notch2 was not expressed in astrocytomas. The percentage of immunopositive tumor cells and level of Notch1 expression was increased with tumor grade. In addition, overexpression of Notch2 was detected in medulloblastomas in contrast to low or no expression of Notch1, 3, 4. Differential expression of Notch1, 2, 3, 4 is detected in astrocytomas and medulloblastomas, that may be related to their different roles playing in the development of brain tumors.

    Background Small size at birth and rapid growth in early life are associated with increased risk of cardiovascular disease in later life. Short children born small for gestational age (SGA) are treated with growth hormone (GH), inducing catch-up in length. Leukocyte telomere length (LTL) is a marker of biological age and shorter LTL is associated with increased risk of cardiovascular disease. Objectives To investigate whether LTL is influenced by birth size, childhood growth and long-term GH treatment. Methods We analyzed LTL in 545 young adults with differences in birth size and childhood growth patterns. Previously GH-treated young adults born SGA (SGA-GH) were compared to untreated short SGA (SGA-S), SGA with spontaneous catch-up to a normal body size (SGA-CU), and appropriate for gestational age with a normal body size (AGA-NS). LTL was measured using a quantitative PCR assay. Results We found a positive association between birth length and LTL (p = 0.04), and a trend towards a positive association between birth weight and LTL (p = 0.08), after adjustments for gender, age, gestational age and adult body size. Weight gain during infancy and childhood and fat mass percentage were not associated with LTL. Female gender and gestational age were positively associated with LTL, and smoking negatively. After adjustments for gender, age and gestational age, SGA-GH had a similar LTL as SGA-S (p = 0.11), SGA-CU (p = 0.80), and AGA-NS (p = 0.30). Conclusions Larger size at birth is positively associated with LTL in young adulthood. Growth patterns during infancy and childhood are not associated with LTL. Previously GH-treated young adults born SGA have similar LTL as untreated short SGA, SGA with spontaneous catch-up and AGA born controls, indicating no adverse effects of GH-induced catch-up in height on LTL.

Our previous study of cathodal transcranial direct current stimulation (tDCS in children with focal epilepsy showed significant reduction in epileptiform discharges. We hypothesized that cathodal tDCS when applied over the primary motor cortex (M1 combined with pharmacologic treatment will be more effective for reducing seizure frequency in patients with LGS than pharmacologic treatment alone. Material and Method: Study participants were randomized to receive either (1 pharmacologic treatment with 5-consecutive days of 2 mA cathodal tDCS over M1 for 20 min or (2 pharmacologic treatment plus sham tDCS. Measures of seizure frequency and epileptic discharges were performed before treatment and again immediately post-treatment and 1-, 2-, 3-, and 4-week follow-up. Result: Twenty two patients with LGS were enrolled. Participants assigned to the active tDCS condition reported significantly more pre- to post-treatment reductions in seizure frequency and epileptic discharges that were sustained for 3 weeks after treatment.Conclusion: Five consecutive days of cathodal tDCS over M1 combined with pharmacologic treatment appears to reduce seizure frequency and epileptic discharges. Further studies of the potential mechanisms of tDCS in the LGS are warranted.Trial Registration: ClinicalTrials.gov, NCT02731300 (https://register.clinicaltrials.gov.

    Tuberous sclerosis complex is a genetic, multisystemic disorder characterized by circumscribed benign lesions (hamartomas) in several organs, including brain. This is the result of defects in the TSC1 and/or TSC2 tumor suppressor genes, encoding the hamartin-tuberin complex that inhibits the mammalian target of rapamycin pathway. Specific inhibitors of this pathway have been shown to reduce the volume of subependymal giant cell astrocytomas associated with tuberous sclerosis. Congenital lymphedema is rarely seen in association with tuberous sclerosis, with only a few reported cases. Although this association can be coincidental, the dysgenetic lymphatic system can represent a hamartia as a consequence of gene mutation. We describe a child with congenital lymphedema in tuberous sclerosis and associated subependymal giant cell astrocytoma who experienced lymphangitis under treatment with mammalian target of rapamycin inhibitors. Because our patient did not show worsening of lymphedema, congenital lymphedema does not seem to be a contraindication for this therapy.

    Background: Family-based behavioral treatments are effective ways to promote children's weight management through healthy eating and exercise. However, programs typically have high attrition and low attendance. The aim of this study was to obtain in-depth caregiver input on barriers and facilitators to participate in a family-based, behavioral childhood obesity treatment program. Methods: Three focus groups were facilitated among 21 parents/guardians at 2 school-based health centers and 1 federally qualified health center. Audio recordings were transcribed and uploaded into NVivo software to assist in thematic coding. Results: Focus group participants were females aged 18-57 years, of whom 71% were black, and 81% were not married. Participants listed numerous barriers: lack of time, frustration from prior unsuccessful weight-loss attempts, and the perceived cost of healthy foods and exercise options. Facilitators included a convenient location, a supportive weight-loss program leader, and rewards for the child's progress. Conclusion: Future interventions should incorporate caregivers' perspectives to develop sustainable, feasible strategies for the treatment of childhood obesity. PMID:28331454

  12. The influence of antineoplastic treatment on the weight of survivors of childhood cancer

    Directory of Open Access Journals (Sweden)

    Julia Ferrari Carneiro Teixeira

    Full Text Available Abstract Purpose: Obesity is a late effect in survivors of childhood cancer and correlates with chronic complications. Survivors of leukemia, brain tumors, and hematopoietic stem cell transplantation are more likely to develop obesity resulting from treatment modalities such as radiotherapy and glucocorticoids. This paper analyzes and integrates the current data available to health professionals in order to clarify strategies that can be used to treat and prevent obesity in childhood cancer survivors. Sources: This is a literature review from on scientifically reliable electronic databases. We selected articles published in the last five years and earlier articles of great scientific importance. Data synthesis: The mechanisms involved in the pathophysiology of obesity in cancer survivors are not completely understood, but it is believed that damage to the hypothalamus and endocrine disorders such as insulin resistance, leptin resistance, and hormone deficiency may be involved. The body composition of this group includes a predominance of adipose tissue, especially in those undergoing hematopoietic stem cell transplant and total body irradiation. The use of body mass index in these patients may lead to an underestimation of individuals' risk for metabolic complications. Conclusion: Early identification of groups using accurate anthropometric assessments, interventional treatment, and/or preventative measures and counseling is essential to minimize the adverse effects of treatment. Physical activity and healthy eating to promote adequacy of weight in the whole population should be encouraged.

    Traumatic experiences and their biopsychosocial sequelae present complex challenges in substance use treatment. For women with substance use problems, childhood sexual abuse (CSA), intimate partner violence exposure (IPV), posttraumatic stress disorder (PTSD), and overall psychological distress are often co-occurring concerns. To address gaps in knowledge and to strengthen practice regarding these critical issues in substance use treatment, we drew upon cross-sectional and longitudinal data from baseline and 12-month interviews with a random sample of 416 women in methadone treatment to examine relationships between CSA characteristics, particularly the presence of force and involvement of family, IPV, and mental health concerns. Although CSA involving force and family was not associated with IPV as hypothesized, it was associated with increased risk of PTSD and overall psychological distress. The multivariate findings underscore the psychological vulnerabilities associated with CSA involving force and family and suggest that drug use and financial circumstances may be important targets to reduce IPV risk.

    Bone sarcoma as a second malignancy is rare but highly fatal. The present knowledge about radiation-absorbed organ dose-response is insufficient to predict the risks induced by radiation therapy techniques. The objective of the present study was to assess the treatment-induced risk for bone sarcoma following a childhood cancer and particularly the related risk of radiotherapy. Therefore, a retrospective cohort of 4,171 survivors of a solid childhood cancer treated between 1942 and 1986 in France and Britain has been followed prospectively. We collected detailed information on treatments received during childhood cancer. Additionally, an innovative methodology has been developed to evaluate the dose-response relationship between bone sarcoma and radiation dose throughout this cohort. The median follow-up was 26 years, and 39 patients had developed bone sarcoma. It was found that the overall incidence was 45-fold higher [standardized incidence ratio 44.8, 95 % confidence interval (CI) 31.0-59.8] than expected from the general population, and the absolute excess risk was 35.1 per 100,000 person-years (95 % CI 24.0-47.1). The risk of bone sarcoma increased slowly up to a cumulative radiation organ absorbed dose of 15 Gy [hazard ratio (HR) = 8.2, 95 % CI 1.6-42.9] and then strongly increased for higher radiation doses (HR for 30 Gy or more 117.9, 95 % CI 36.5-380.6), compared with patients not treated with radiotherapy. A linear model with an excess relative risk per Gy of 1.77 (95 % CI 0.6213-5.935) provided a close fit to the data. These findings have important therapeutic implications: Lowering the radiation dose to the bones should reduce the incidence of secondary bone sarcomas. Other therapeutic solutions should be preferred to radiotherapy in bone sarcoma-sensitive areas.

    This study investigated the role of parental motivation (importance, confidence and readiness) for predicting dropout and outcome from family-based behavioral treatment for childhood obesity. Parent and child demographics, adherence to treatment, and weight loss parameters were also explored as potential predictors. Eighty-four obese children (BMI-standard deviation scores (SDS) >2.14) and a participating parent with each child started treatment consisting of 12 weeks of group and individual treatment sessions (24 sessions total) delivered over a period of 18 weeks. Sixty-one families (73%) completed treatment and attended follow-up at 1 year after treatment. Child session attendance and completion of self-monitoring records served as measures of adherence. In regression analyses, parent reports (pretreatment) of confidence for doing well in treatment was the strongest predictor of treatment completion (P = 0.003) as well as early treatment response (weight loss at week 5) (P = 0.003). This variable remained a significant predictor of child weight loss at post-treatment (P = 0.014), but was not associated with child outcome at 1-year follow-up (P > 0.05). The only significant predictor of child weight loss at that point was child baseline weight (P = 0.001). However, pretreatment parent ratings of importance of and readiness for treatment did not predict dropout or weight loss at any point. The results underscore the importance of addressing parental motivation, specifically parental confidence for changing lifestyle related behaviors, early in the treatment process. Doing so may reduce treatment dropout and enhance treatment outcome.

    This paper described the therapeutic efficacy of immunosuppressive (IS) treatment agents (ATG and CSA) and androgens in the treatment of childhood aplastic anemia (AA). The results showed that the overall curative rate was 52.4% in the ATG therapy group (21 cases) and 58.3% in the CSA therapy group (12 cases) respectively. The effective rate of all patients (SAA and CAA) was 58.1% in the IS group (18/31) and 40.4% in the androgens group (42/104), P>0.05. But, in the childhood patients with SAA, the clinical effective rate was 68.4% in the IS group and 7.9% in the androgens group, P<0.01. The laboratory tests revealed that the majority of the AA patients displalyed abnormal immunological states: inversed CD4/ CD8 ratio and increased IL-2 activity. These abnormal immunological states could be normalized in several patients when clinical response was abtained following IS therapy with ATG and CSA.

    Attention bias modification training (ABMT) is a promising treatment for anxiety disorders. Recent evidence suggests that attention training towards positive stimuli, using visual-search based ABMT, has beneficial effects on anxiety and attention biases in children. The present study extends this prior research using distinctive techniques designed to increase participant learning, memory consolidation, and treatment engagement. Fifty-nine clinically anxious children were randomly assigned to the active treatment condition (ATC) (N = 31) or waitlist control condition (WLC) (N = 28). In the ATC, children completed 12 treatment sessions at home on computer in which they searched matrices for a pleasant or calm target amongst unpleasant background pictures, while also engaging in techniques designed to consolidate learning and memory for these search strategies. No contact was made with children in the WLC during the wait period. Diagnostic, parent- and child-reports of anxiety and depressive symptoms, externalising behaviour problems and attention biases were assessed pre- and post-condition and six-months after treatment. Children in the ATC showed greater improvements on multiple clinical measures compared to children in the WLC. Post-treatment gains improved six-months after treatment. Attention biases for angry and happy faces did not change significantly from pre-to post-condition. However, larger pre-treatment attention bias towards threat was associated with greater reduction in anxiety at post-treatment. Also, children who showed greater consolidation of learning and memory strategies during treatment achieved greater improvement in global functioning at post-treatment. Attention training towards positive stimuli using enhanced visual-search procedures appears to be a promising treatment for childhood anxiety disorders.

    Full Text Available Background: High-grade astrocytoma (Grade 4 or glioblastoma multiforme (GBM are deadly brain tumors. New therapies attempt to increase lifetime and quality of life in patients with malignant astrocytoma. O6-methylguanine-DNA methyltransferase (MGMT enzyme expression may be effective in prognosis and response to treatment of these patients. The aim of this study was assessment of MGMT enzyme expression in patients with astrocytoma Grade 4. Materials and Methods: In this study, 48 patients with GBM that were treated with surgery, chemotherapy and radiotherapy were investigated and followed-up for 47 months for the survival rate. Pathology blocks of patients were examined for MGMT enzyme expression using immunohistochemistry method. Results: The patients were 34 males and 14 females. The ages ranged from 24 to 77 years, with a mean age of 53.52 ± 13.39 years. There was no significant difference between two groups (positive and negative MGMT enzyme expression in overall survival (median [range] 11.5 [4-30] vs. 13 [5-22], P = 0.9. The results of our study showed that patients although who were undergone near total surgery had higher overall survival than the group of patients who had biopsy only however, it was not significant. Patients who were treated with temozolomide (TMZ (Temodal, Merck Canada had significant overall median survival (14.5 more than the patients who were treated with Procarbazine (Roche, Swiss-Lomustine (Lilly, USA-Vincristine (Lilly, USA regimen (8.75 (P < 0.05. Conclusion: O6-methylguanine-DNA methyltransferase enzyme expression had no effect on survival of patients with Grade 4 brain astrocytoma TMZ may increase survival rate.

  1. Dexamethasone acts as a radiosensitizer in three astrocytoma cell lines via oxidative stress.

    Glucocorticoids (GCs), which act on stress pathways, are well-established in the co-treatment of different kinds of tumors; however, the underlying mechanisms by which GCs act are not yet well elucidated. As such, this work investigates the role of glucocorticoids, specifically dexamethasone (DEXA), in the processes referred to as DNA damage and DNA damage response (DDR), establishing a new approach in three astrocytomas cell lines (CT2A, APP.PS1 L.1 and APP.PS1 L.3). The results show that DEXA administration increased the basal levels of gamma-H2AX foci, keeping them higher 4h after irradiation (IR) of the cells, compared to untreated cells. This means that DEXA might cause increased radiosensitivity in these cell lines. On the other hand, DEXA did not have an apparent effect on the formation and disappearance of the 53BP1 foci. Furthermore, it was found that DEXA administered 2h before IR led to a radical change in DNA repair kinetics, even DEXA does not affect cell cycle. It is important to highlight that DEXA produced cell death in these cell lines compared to untreated cells. Finally and most important, the high levels of gamma-H2AX could be reversed by administration of ascorbic acid, a potent blocker of reactive oxygen species, suggesting that DEXA acts by causing DNA damage via oxidative stress. These exiting findings suggest that DEXA might promote radiosensitivity in brain tumors, specifically in astrocytoma-like tumors.

    In this article, the authors present a psychodynamically oriented psychotherapy approach for posttraumatic stress disorder (PTSD) related to childhood abuse. This neurobiologically informed, phase-oriented treatment approach, which has been developed in Germany during the past 20 years, takes into account the broad comorbidity and the large degree of ego-function impairment typically found in these patients. Based on a psychodynamic relationship orientation, this treatment integrates a variety of trauma-specific imaginative and resource-oriented techniques. The approach places major emphasis on the prevention of vicarious traumatization. The authors are presently planning to test the approach in a randomized controlled trial aimed at strengthening the evidence base for psychodynamic psychotherapy in PTSD.

    Full Text Available Rates of childhood and adult trauma are high among incarcerated persons. In addition to criminality, childhood trauma is associated with the risk for emotional disorders (e.g., depression and anxiety and co-morbid conditions such as alcohol and drug abuse and antisocial behaviors in adulthood. This paper develops rates of childhood and adult trauma and examines the impact of age-of-onset and type-specific trauma on emotional problems and behavior for a sample of incarcerated males (N~4,000. Prevalence estimates for types of trauma were constructed by age at time of trauma, race and types of behavioral health treatment received while incarcerated. HLM models were used to explore the association between childhood and adult trauma and depression, anxiety, substance use, interpersonal problems, and aggression problems (each model estimated separately and controlling for age, gender, race, time incarcerated, and index offense. Rates of physical, sexual, and emotional trauma were higher in childhood than adulthood and ranged from 44.7% (physical trauma in childhood to 4.5% (sexual trauma in adulthood. Trauma exposure was found to be strongly associated with a wide range of behavioral problems and clinical symptoms. Given the sheer numbers of incarcerated men and the strength of these associations, targeted intervention is critical.

    Full Text Available Background and Design: Severe psoriasis in childhood has a significant morbidity and can warrant the use of systemic agents, although there are very little information in this group. We aimed to show the results of acitretin treatment in children with severe psoriasis, in this study.Material and Method: We have retrospectively reviewed the notes of all 18 children treated with acitretin at Ondokuz Mayıs University Hospital. Patients’ responses to treatment, total treatment durations and acitretine dosage were recorded. Additionally, the laboratory results during the whole follow-up period and bone surveys for 3 patients who received long term treatment were evaluated.Results: Of the 18 patients reviewed, 2 (%11.1 responded with clearance of psoriasis, 10 (%55.5 responded well with small residual plaques. Two patients needed two courses of acitretine (11 and 12 months, 1 patient needed three courses for 15 months and 1 needed 5 courses for 24 months. Two patients stopped treatment due to mucocutaneous side effects at 4th and 5th months. There were no other adverse events.Conclusion: We propose that when carefully monitored, acitretine is a safe and efficacious treatment option for severe psoriasis in children.

    Full Text Available Objective This study aimed to assess the clinicoradiological features and treatment outcome of intracranial dissecting aneurysms (IDAs in childhood.Methods We conducted a retrospective study of pediatric patients who were treated for spontaneous IDAs in our institute between January 2010 and December 2015. The clinical presentation, aneurysm characteristics, treatment modality, and outcome were studied. Results We studied 26 pediatric patients (mean age, 13.4 years; range, 4–18 years with 31 IDAs who comprised 6.9% of all IDA patients treated during the same period. Seventeen (65.4% patients were male and nine (34.6% were female. The incidence of large (≥10mm in size or giant aneurysms (≥25mm in size was 65.5%. Twenty-one (80.8% patients underwent endovascular or surgical treatment and five (19.2% received conservative treatment. Perioperative complications occurred in three patients, in whom two eventually recovered completely with a Glasgow Outcome Scale (GOS score of 5 and one partially recovered with a GOS score 4. Overall, 25 (96.2% patients had a favorable outcome and one (3.8% had an unfavorable outcome at a mean follow-up of 22.8 months (range, 6–60 months.Conclusions Pediatric IDAs are rare. In this series, endovascular management was a relatively safe and effective method of treatment for pediatric IDAs. However, continued follow-up is required because of the possibility of aneurysm recurrence and de novo aneurysm formation after treatment.

    Full Text Available BACKGROUND: In some patients, local surgery-related complications are diagnosed many years after surgery for aortic coarctation. The purposes of this study were: (1 to systematically evaluate asymptomatic adults after Dacron patch repair in childhood, (2 to estimate the formation rate of secondary thoracic aortic aneurysms (TAAs and (3 to assess outcomes after intravascular treatment for TAAs. METHODS: This study involved 37 asymptomatic patients (26 female and 11 male who underwent surgical repair of aortic coarctation in the childhood. After they had reached adolescence, patients with secondary TAAs were referred to endovascular repair. RESULTS: Follow-up studies revealed TAA in seven cases (19% (including six with the gothic type of the aortic arch and mild recoarctation in other six (16%. Six of the TAA patients were treated with stentgrafts, but one refused to undergo an endovascular procedure. In three cases, stengrafts covered the left subclavian artery (LSA, in another the graft was implanted distally to the LSA. In two individuals, elective hybrid procedures were performed with surgical bypass to the supraaortic arteries followed by stengraft implantation. All subjects survived the secondary procedures. One patient developed type Ia endoleak after stentgraft implantation that was eventually treated with a debranching procedure. CONCLUSIONS: The long-term course of clinically asymptomatic patients after coarctation patch repair is not uncommonly complicated by formation of TAAs (particularly in individuals with the gothic pattern of the aortic arch that can be treated effectively with stentgrafts. However, in some patients hybrid procedures may be necessary.

    This paper reports the latest survival data for French childhood cancer patients at the national level. Data from the two French National Registries of Childhood Cancer (Haematopoietic Malignancies and Solid Tumours) were used to describe survival outcomes for 15,479 children diagnosed with cancer between 2000 and 2008 in mainland France. The overall survival was 91.7% at 1 year, 86.9% at 2 years and 81.6% at 5 years. Relative survival did not differ from overall survival even for infants. Survival was lower among infants for lymphoblastic leukaemia and astrocytoma, but higher for neuroblastoma. For all cancers considered together, 5-year survival increased from 79.5% in the first (2000-2002) diagnostic period to 83.2% in the last (2006-2008) period. The improvement was significant for leukaemia, both myeloid and lymphoid, central nervous system tumours (ependymoma) and neuroblastoma. The results remained valid in the multivariate analysis, and, for all cancers combined, the risk of death decreased by 20% between 2000-2002 and 2006-2008. The figures are consistent with various international estimates and are the result of progress in treatment regimens and collaborative clinical trials. The challenge for the French registries is now to study the long-term follow-up of survivors to estimate the incidence of long-term morbidities and adverse effects of treatments.

    1975-07-01

    The first results covering the assessment period phase of a systematic study of 50 borderline psychotic and 50 psychotic adolescents are described. These 100 adolescents comprised one-third of the total number of admissions to an adolescent department during the years from 1968 to 1975. There were 58 boys and 42 girls; 53 of the 100 cases had been psychiatrically ill in childhood with evident symptoms. In 22 cases, there was positive information supporting the fact that the patients had been healthy in childhood. The rest (25 cases) were classified under "unclarified picture", showing non specific symptoms. It is concluded that in this material more than half of the adolescents had shown some instability before puberty. The illnesses described in childhood are categorised as infantile borderline psychosis, borderline psychosis probable, and other psychiatric illnesses. A shift in diagnosis is often seen in the individual case, but the symptoms in childhood and in adolescence have many similarities. The necessary treatment in childhood has not been given in one-third of the cases. The possible reasons for this are discussed. In spite of much effort in some cases and because of resistance to therapy or the proposal of inadequate therapy in others, the therapeutic possibilities in childhood have not been fully realised. It is recommended that more emphasis be placed on the emotional development in the evaluation of the children. In the treatment, development of interpersonal relationships through individual, family and/or milieu therapy should be stressed. A follow-up of children with symptoms in childhood left untreated and a teamwork between child psychiatrist and adult psychiatrist with longitudinal studies is suggested.

  11. Intensive treatment with ultrasound visual feedback for speech sound errors in childhood apraxia

    Full Text Available Ultrasound imaging is an adjunct to traditional speech therapy that has shown to be beneficial in the remediation of speech sound errors. Ultrasound biofeedback can be utilized during therapy to provide clients additional knowledge about their tongue shapes when attempting to produce sounds that are in error. The additional feedback may assist children with childhood apraxia of speech in stabilizing motor patterns, thereby facilitating more consistent and accurate productions of sounds and syllables. However, due to its specialized nature, ultrasound visual feedback is a technology that is not widely available to clients. Short-term intensive treatment programs are one option that can be utilized to expand access to ultrasound biofeedback. Schema-based motor learning theory suggests that short-term intensive treatment programs (massed practice may assist children in acquiring more accurate motor patterns. In this case series, three participants ages 10-14 diagnosed with childhood apraxia of speech attended 16 hours of speech therapy over a two-week period to address residual speech sound errors. Two participants had distortions on rhotic sounds, while the third participant demonstrated lateralization of sibilant sounds. During therapy, cues were provided to assist participants in obtaining a tongue shape that facilitated a correct production of the erred sound. Additional practice without ultrasound was also included. Results suggested that all participants showed signs of acquisition of sounds in error. Generalization and retention results were mixed. One participant showed generalization and retention of sounds that were treated; one showed generalization but limited retention; and the third showed no evidence of generalization or retention. Individual characteristics that may facilitate generalization are discussed. Short-term intensive treatment programs using ultrasound biofeedback may result in the acquisition of more accurate motor

    Full Text Available Dysembryoplastic neuroepithelial tumor (DNT, described in 1988 and introduced in the WHO classification in 1993, affects predominantly children or young adults causing intractable complex partial seizures. Since it is benign and treated with surgical resection, its recognition is important. It has similarities with low-grade gliomas and gangliogliomas, which may recur and become malignant. OBJECTIVES: To investigate whether DNT was previously diagnosed as astrocytoma, oligodendroglioma, or ganglioglioma and to determine its frequency in a series of low-grade glial/glio-neuronal tumors. METHODS: Clinical, radiological, and histological aspects of 58 tumors operated from 1978 to 2008, classified as astrocytomas (32, including 8 pilocytic, oligodendrogliomas (12, gangliogliomas (7, and DNT (7, were reviewed. RESULTS: Four new DNT, one operated before 1993, previously classified as astrocytoma (3 and oligodendroglioma (1, were identified. One DNT diagnosed in 2002 was classified once more as angiocentric glioma. Therefore, 10 DNT (17.2% were identified. CONCLUSIONS: Clinical-radiological and histopathological correlations have contributed to diagnose the DNT.

    2014-01-01

    Full Text Available Objective: Most cases of idiopathic nephrotic syndrome in childhood are responsive to corticosteroids. However, there is a small group of children that demonstrate steroid resistance (steroid-resistant nephrotic syndrome; SRNS, steroid dependence, or that frequently relapse (frequent-relapse steroid-sensitive nephrotic syndrome; FR-SSNS which are more clinically difficult to treat. Therefore, second-line immunosuppressants, such as alkylating agents, calcineurin inhibitors, antimetabolites and, more recently, rituximab, have been used with varying success. The objective was to evaluate the response rates of various second-line therapies in the treatment of childhood nephrotic syndrome. Study Design: A retrospective chart review of pediatric subjects with idiopathic nephrotic syndrome was conducted at a single tertiary care center (2007-2012. Drug responses were classified as complete response, partial response, and no response. Results: Of the 188 charts reviewed, 121 children were classified as SSNS and 67 children as SRNS; 58% were classified as FR-SSNS. Sixty-five subjects were diagnosed with focal segmental glomerulosclerosis via biopsy. Follow-up ranged from 6 months to 21 years. The combined rate of complete and partial response for mycophenolate mofetil (MMF was 65% (33/51 in SSNS and 67% (6/9 in SRNS. For tacrolimus, the response rate was 96% (22/23 for SSNS and 77% (17/22 for SRNS. Eighty-three percent (5/6 of SSNS subjects treated with rituximab went into complete remission; 60% relapsed after B-cell repletion. Eight refractory subjects were treated with combined MMF/tacrolimus/corticosteroid therapy with a 75% response rate. Conclusion: Our experience demonstrates that older medications can be replaced with newer ones such as MMF, tacrolimus, and rituximab with good outcomes and better side effect profiles. The treatment of refractory cases with combination therapy is promising.

    Study objectives were to develop a treatment manual for a family-focused intervention for depressed school-aged children, evaluate its feasibility and acceptability, and complete an initial open trial to examine treatment effects. Nine young people meeting criteria for depression (major depressive disorder, dysthymic disorder, or depression not otherwise specified), completed a 12-week family intervention, and were assessed immediately and at 9 months following treatment completion. The intervention presented an interpersonal model of how depressive symptoms are maintained, and emphasized developing family strategies for altering interpersonal processes, supporting recovery and enhancing resilience. At posttreatment 66% of the young people had recovered from their depressive episodes; by 9 months posttreatment 77% had recovered. Significant improvements in global functioning were noted. There were no relapses in the follow-up period and no instances of suicidal behavior during the intervention or follow-up. Mothers' and fathers' Child Behavior Checklist reports and children's self reports indicated significant symptom reductions. Exploratory analyses suggest particular benefit for young people with parents high in criticism. The family-focused intervention for childhood-onset depression demonstrated gains similar to those seen with empirically supported treatments for depressed adolescents and superior to those seen in naturalistic studies of depression outcomes. This favorable risk/benefit profile supports the value of a randomized controlled trial.

    Full Text Available Background: The early and late benign occipital epilepsies of childhood (BOEC are described as two discrete electro-clinical syndromes, eponymously known as Panayiotopoulos and Gastaut syndromes. The purpose of this study was to identify predictors of failure to respond to the initial antiepileptic drug (AED. Materials and Methods: A total of 42 children with BOEC were enrolled. Predictive factors were analyzed by survival methods. Results: Among the 42, 25 patients (59.5% were boys and 17 (40.5% were girls and the mean age at the seizure onset was 7.46 ± 2.65 years (4-14 years. Of the 42 patients, 34 (81.0% were treated relatively successfully with the first AED treatment, and 8 (19.0% were not responded initial AED treatment. There was no correlation between response to initial AED treatment and sex, consanguinity, epilepsy history of family, age of seizure onset, frequency of seizures, history of status epilepticus, duration of starting first treatment, findings on electroencephalogram. However, history of febrile seizure and type of BOEC were significantly associated with failure risk. Conclusions: Factors predicting failure to respond to the AED were history of febrile seizure and type of BOEC in children with BOEC.

    Full Text Available Purpose. To identify and synthesize the best available evidence on the effectiveness of interventions for universal prevention, detection and treatment of early childhood maltreatment (0-4 years. Design. Scoping Review. Data sources. MEDLINE, LILACS, PsycINFO, Psyclist, SciELO, ISI Web of Knowledge, Science Direct, EBSCO, EMBASE, Cochrane Library, DARE, Google Scholar and UNICEF Base. Methods. A variety of keywords were used to identify quantitative experimental and observational studies on detection, prevention and treatment strategies in different situations of child maltreatment. Sexual abuse was excluded. The search spanned from 2002 to 2012, in English and Spanish. Results. Of 105 articles, 36 met the selection criteria. In prevention, the best evaluated strategies were parenting programs based on cognitive or cognitive-behavioral approach and interactive learning strategies. In detection, only two instruments were identified with optimum specificity and positive predictive value. In treatment, a variety of treatment strategies were identified with favorable effects on behavioral, functional and psycho affective indicators. The population relevance of these interventions is unclear, as the differential effectiveness of these therapeutic approaches. Conclusions. There are many child maltreatment prevention strategies at the individual and family level. The instruments used for detection are not reliable for use at the collective level. Insofar as therapy, not enough evidence was found both in quality and quantity to favor one intervention over another. It is recommended to understand the problem from the public health perspective and to generate multisectoral and interdisciplinary approaches.

  1. Impact monitoring of the national scale up of zinc treatment for childhood diarrhea in Bangladesh: repeat ecologic surveys.

    Full Text Available BACKGROUND: Zinc treatment of childhood diarrhea has the potential to save 400,000 under-five lives per year in lesser developed countries. In 2004 the World Health Organization (WHO/UNICEF revised their clinical management of childhood diarrhea guidelines to include zinc. The aim of this study was to monitor the impact of the first national campaign to scale up zinc treatment of childhood diarrhea in Bangladesh. METHODS/FINDINGS: Between September 2006 to October 2008 seven repeated ecologic surveys were carried out in four representative population strata: mega-city urban slum and urban nonslum, municipal, and rural. Households of approximately 3,200 children with an active or recent case of diarrhea were enrolled in each survey round. Caretaker awareness of zinc as a treatment for childhood diarrhea by 10 mo following the mass media launch was attained in 90%, 74%, 66%, and 50% of urban nonslum, municipal, urban slum, and rural populations, respectively. By 23 mo into the campaign, approximately 25% of urban nonslum, 20% of municipal and urban slum, and 10% of rural under-five children were receiving zinc for the treatment of diarrhea. The scale-up campaign had no adverse effect on the use of oral rehydration salt (ORS. CONCLUSIONS: Long-term monitoring of scale-up programs identifies important gaps in coverage and provides the information necessary to document that intended outcomes are being attained and unintended consequences avoided. The scale-up of zinc treatment of childhood diarrhea rapidly attained widespread awareness, but actual use has lagged behind. Disparities in zinc coverage favoring higher income, urban households were identified, but these were gradually diminished over the two years of follow-up monitoring. The scale up campaign has not had any adverse effect on the use of ORS. Please see later in the article for the Editors' Summary.

  2. The role of anxiety in the development, maintenance, and treatment of childhood aggression.

    Granic, Isabela

    2014-11-01

    The majority of aggressive children exhibit symptoms of anxiety, yet none of our developmental models of aggression incorporate the role of anxiety, and our treatments ignore this comorbidity. This article outlines a novel theoretical model that specifies three hypotheses about comorbid anxious and aggressive children: (a) unpredictable parenting induces anxiety in children that in turn triggers aggressive behavior; (b) prolonged periods of anxiety deplete children's capacity to inhibit impulses and trigger bouts of aggression, and aggression in turn functions to regulate levels of anxiety; and (c) minor daily stressors give rise to anxiety while cognitive perseveration maintains anxious moods, increasingly disposing children to aggress. Little or no research has directly tested these hypotheses. Extant research and theory consistent with these claims are herein reviewed, and future research designs that can test them specifically are suggested. The clinical implications most relevant to the hypotheses are discussed, and to improve the efficacy of treatments for childhood aggression, it is proposed that anxiety may need to be the primary target of treatment.

    Medical advances over the last several decades, including CNS prophylaxis, have greatly increased survival in children with leukemia. As survival rates have increased, clinicians and scientists have been afforded the opportunity to further develop treatments to improve the quality of life of survivors by minimizing the long-term adverse effects. When evaluating the effect of antileukemia therapy on the developing brain, magnetic resonance (MR) imaging has been the preferred modality because it quantifies morphologic changes objectively and noninvasively. Computer-aided detection of changes on neuroimages enables us to objectively differentiate leukoencephalopathy from normal maturation of the developing brain. Quantitative tissue segmentation algorithms and relaxometry measures have been used to determine the prevalence, extent, and intensity of white matter changes that occur during therapy. More recently, diffusion tensor imaging has been used to quantify microstructural changes in the integrity of the white matter fiber tracts. MR perfusion imaging can be used to noninvasively monitor vascular changes during therapy. Changes in quantitative MR measures have been associated, to some degree, with changes in neurocognitive function during and after treatment. In this review, we present recent advances in quantitative evaluation of MR imaging and discuss how these methods hold the promise to further elucidate the pathophysiologic effects of treatment for childhood leukemia.

    Subependymal giant cell astrocytoma (SEGA) is a rare tumor occurring almost exclusively in patients with tuberous sclerosis complex. Although open resection remains the standard therapy, complication rates remain high. To minimize morbidity, less invasive approaches, such as endoscope-assisted resection, radiosurgery, and chemotherapy with mTOR pathway inhibitors, are also used to treat these lesions. Laser interstitial thermal therapy (LITT) is a relatively new modality that is increasingly used to treat a variety of intracranial lesions. In this report, the authors describe two pediatric cases of SEGA that were treated with LITT. In both patients the lesion responded well to this treatment modality, with tumor shrinkage observed on follow-up MRI. These cases highlight the potential of LITT to serve as a viable minimally invasive therapeutic approach to the management of SEGAs in the pediatric population.

    Pilomyxoid astrocytoma (PMA) is a relatively new tumor entity which has been added to the 2007 WHO Classification of tumors of the central nervous system. The goal of this study is to utilize arterial spin labeling (ASL) perfusion imaging to differentiate PMA from pilocytic astrocytoma (PA). Pulsed ASL and conventional MRI sequences of patients with PMA and PA in the past 5 years were retrospectively evaluated. Patients with history of radiation or treatment with anti-angiogenic drugs were excluded. A total of 24 patients (9 PMA, 15 PA) were included. There were statistically significant differences between PMA and PA in mean tumor/gray matter (GM) cerebral blood flow (CBF) ratios (1.3 vs 0.4, p < 0.001) and maximum tumor/GM CBF ratio (2.3 vs 1, p < 0.001). Area under the receiver operating characteristic (ROC) curves for differentiation of PMA from PA was 0.91 using mean tumor CBF, 0.95 using mean tumor/GM CBF ratios, and 0.89 using maximum tumor/GM CBF. Using a threshold value of 0.91, the mean tumor/GM CBF ratio was able to diagnose PMA with 77 % sensitivity, 100 % specificity, and a threshold value of 0.7, provided 88 % sensitivity and 86 % specificity. There was no statistically significant difference between the two tumors in enhancement pattern (p = 0.33), internal architecture (p = 0.15), or apparent diffusion coefficient (ADC) values (p = 0.07). ASL imaging has high accuracy in differentiating PMA from PA. The result of this study may have important applications in prognostication and treatment planning especially in patients with less accessible tumors such as hypothalamic-chiasmatic gliomas. (orig.)

    1998-01-01

    Objective:To study the relationship between deletion of P16 gene and occurrence and progression of astrocytomas. Methods: The techniques of polymerase chain reaction (PCR) and immunohistochemistry were used to detect the deletion of exon2 of P16 gene and expression of P16 gene in 52 cases of Brain astrocytoma.Results: The deletion rate of exon2 of P16 gene in the tumors analyzed was 34.6%. Most of them with deletion of exon2 of p16 gene were high grade astrocytomas (grade Ⅲ 42%, grade Ⅳ 50%). 61.5% of the tumors were absent from expression of p16 and the deletion rate of p16 protein increased with the grade of astrocytoma (X2=10.83, P<0.005). Conclusion: Deletion of p16 gene and protein may correlate with the malignant progression of astrocytoma.

    Full Text Available Abstract Background Loss of heterozygosity of chromosome 10q26 has been shown to be associated with the aggressiveness of astrocytic tumors (or astrocytomas, but the responsible gene(s residing in this region has not been fully identified. The BCCIP gene is located at chromosome 10q26. It encodes a BRCA2 and CDKN1A (p21 interacting protein. Previous studies have shown that down-regulation of BCCIP impairs recombinational DNA repair, G1/S cell cycle checkpoint, p53 trans-activation activity, cytokinesis, and chromosome stability, suggesting a potential role of BCCIP in cancer etiology. In this study, we investigated whether BCCIP is altered in astrocytomas. Methods Genomic DNA from 45 cases of grade IV astrocytic tumor (glioblastoma tissues and 12 cases of normal tissues were analyzed by quantitative PCR. The BCCIP protein expression in 96 cases of grade II–IV astrocytic tumors was detected by immunohistochemistry (IHC. IHC staining of glial fibrillary acid protein (GFAP, a marker for astrocytic cells, was used to identify cells of the astrocytic lineage. Results We found that BCCIP protein is expressed in normal cells with positive staining of GFAP. However, BCCIP protein expression was not detectable in ~45% of all astrocytic tumors, and in > 60% in the grade IV glioblastoma. About 45% glioblastoma have significant (p BCCIP gene copy number when compared to normal DNA. Furthermore, the frequency of lacking BCCIP expression is associated with the aggressiveness of astrocytic tumors. Conclusion Our data implicate a role of BCCIP in astrocytic tumorigenesis, and lack of BCCIP may be used as a marker for astrocytomas.

    Hirschsprung's disease (HD) is a disorder associated with congenital malformation of the enteric nervous system with segmental aganglionosis. Prevailing therapy includes a resection of the affected part of the bowel. However, patients often do not obtain complete functional improvement after surgical treatment. We present the case of a 25-year-old woman who had surgical treatment of HD in early childhood. After that procedure she had clinical features of constipation for years in the end,passing of stool once a week, requiring laxatives and enemas. We diagnosed an incomplete resection of the aganglionic bowel via rectal biopsy and resected the remaining aganglionic segment. Two months after surgery the patient's bowel function improved to a frequency of 1-4 stools per day. We conclude that regular follow-up is required to identify HD patients with persistent alterations of bowel function after surgery. In patients presenting with constipation, recognition of a remaining aganglionic segment or other alterations of the enteric nervous system should be aimed at in an early stage.

    A retrospective study of 21 children with rhabdomyosarcoma treated by brachytherapy to the primary site of the tumor at the Radiotherapy Department of the A.C.Camargo Hospital between january/1980 to june/1993 was undertaken. The main objectives were to comprove the utility of brachytherapy in childhood rhabdomyosarcoma, to evaluate the local control and survival, in association with chemotherapy, to analyze the late effects of the treatment and to determinate the preferential technique to each clinical situation. All patients received brachytherapy to the tumor site. The radioactive isotopes employed were Gold{sup 198}, Cesium{sup 137} and Iridium{sup 192}. The brachytherapy techniques depended on the tumor site, period of treatment, availability of the radioactive material and stage of the disease. Patients treated exclusively by brachytherapy received 40 Gy to 60 Gy. When brachytherapy was associated with external radiotherapy the dose ranged from 20 Gy to 40 Gy. Local control was achieved in 18 of 20 patients (90%). The global survival and local control survival rates were 61.9% (13/21 patients) and 72,2% (13/18 patients) respectively. (author)

    Majority of children with tuberculosis are treated in private sector in India with no available data on management practices. The study assessed diagnostic and treatment practices related to childhood pulmonary tuberculosis among paediatricians in Mumbai's private sector in comparison with International Standards for Tuberculosis Care (ISTC) 2009. In this cross-sectional study, 64 paediatricians from private sector filled self-administered questionnaires. Cough was reported as a symptom of childhood TB by 77.8% of respondents. 38.1% request sputum smear or culture for diagnosis and fewer (32.8%) use it for patients positive on chest radiographs and 32.8% induce sputum for those unable to produce it. Sputum negative TB suspect is always tested with X-ray or tuberculin skin test. 61.4% prescribe regimen as recommended in ISTC and all monitor progress to treatment clinically. Drug-resistance at beginning of treatment is suspected for child in contact with a drug-resistant patient (67.7%) and with prior history of antitubercular treatment (12.9%). About half of them (48%) request drug-resistance test for rifampicin in case of nonresponse after two to three months of therapy and regimen prescribed by 41.7% for multidrug-resistant TB was as per ISTC. The study highlights inappropriate diagnostic and treatment practices for managing childhood pulmonary TB among paediatricians in private sector. PMID:26379705

    This is a systematic review of evidence-based treatments for children exposed to childhood maltreatment. Because exposure to childhood maltreatment has been associated with a broad range of trauma-related psychopathology (e.g., PTSD, anxiety, suicidal ideation, substance abuse) and with aggressive and violent behavior, this review describes psychotherapeutic treatments which focus on former broad range of psychopathological outcomes. A total of 26 randomized controlled clinical trials and seven non-randomized controlled clinical trials published between 2000 and 2012 satisfied the inclusionary criteria and were included. These studies dealt with various kinds of samples, from sexually abused and maltreated children in child psychiatric outpatient clinics or in foster care to traumatized incarcerated boys. A total of 27 studies evaluated psychotherapeutic treatments which used trauma-focused cognitive, behavioral or cognitive-behavioral techniques; only two studies evaluated trauma-specific treatments for children and adolescents with comorbid aggressive or violent behavior; and four studies evaluated psychotherapeutic treatments that predominantly focused on other mental health problems than PTSD and used non-trauma focused cognitive, behavioral or cognitive-behavioral techniques. The results of this review suggest that trauma-focused cognitive-behavioral therapy (TF-CBT) is the best-supported treatment for children following childhood maltreatment. However, in line with increased interest in the diagnosis of complex PTSD and given the likely relationship between childhood maltreatment and aggressive and violent behavior, the authors suggest that clinical practice should address a phase-oriented approach. This review concludes with a discussion of future research directions and limitations.

    The purpose of this study was to assess the use of 1-{sup 11}C-acetate (ACE) as a metabolic tracer for the detection and characterisation of astrocytomas. Positron emission tomography (PET) studies with ACE and 2-{sup 18}F-fluoro-2-deoxy-D-glucose (FDG) were performed sequentially in 26 patients with primary astrocytomas. Images were analysed by visual interpretation and determination of the tumour to cortex ratio (T/C ratio) and standardised uptake value (SUV). The tumour uptake was visually scored into three grades as compared with the contralateral cortex: clearly lower (-), almost equal (+) and clearly higher (++). There were 85% of astrocytomas with ++ ACE uptake, 15% with + ACE uptake and none with - ACE uptake. Only 19% of astrocytomas had ++ FDG uptake. Thirty-seven percent of high-grade astrocytomas had + FDG uptake and 37% had - FDG uptake. The sensitivity and specificity of the FDG T/C ratio in discriminating high-grade from low-grade astrocytomas were 79% and 100%, respectively, at the cutoff value of 0.75. Using 2.33 as the cutoff value of the ACE T/C ratio, the sensitivity and specificity were 42% and 86%, respectively. FDG was better than ACE in discriminating high-grade from low-grade astrocytomas. T/C ratios and SUVs of FDG uptake of tumours correlated with the histological grades, but those of ACE uptake did not. ACE appears to be a promising tracer for use in the detection of primary astrocytomas, but is of limited value in the differentiation of high- and low-grade astrocytomas. ACE is complementary to FDG for the diagnosis and characterisation of astrocytoma. (orig.)

    Background Studies link antibiotic treatment and delivery by cesarean section with increased risk of chronic diseases through changes of the gut-microbiota. We aimed to evaluate the association of broad-spectrum antibiotic treatment during the first two years of life with subsequent onset of childhood type 1 diabetes and the potential effect-modification by mode of delivery. Materials and Methods A Danish nationwide cohort study including all singletons born during 1997–2010. End of follow-up by December 2012. Four national registers provided information on antibiotic redemptions, outcome and confounders. Redemptions of antibiotic prescriptions during the first two years of life was classified into narrow-spectrum or broad-spectrum antibiotics. Children were followed from age two to fourteen, both inclusive. The risk of type 1 diabetes with onset before the age of 15 years was assessed by Cox regression. A total of 858,201 singletons contributed 5,906,069 person-years, during which 1,503 children developed type 1 diabetes. Results Redemption of broad-spectrum antibiotics during the first two years of life was associated with an increased rate of type 1 diabetes during the following 13 years of life (HR 1.13; 95% CI 1.02 to 1.25), however, the rate was modified by mode of delivery. Broad-spectrum antibiotics were associated with an increased rate of type 1 diabetes in children delivered by either intrapartum cesarean section (HR 1.70; 95% CI 1.15 to 2.51) or prelabor cesarean section (HR 1.63; 95% CI 1.11 to 2.39), but not in vaginally delivered children. Number needed to harm was 433 and 562, respectively. The association with broad-spectrum antibiotics was not modified by parity, genetic predisposition or maternal redemption of antibiotics during pregnancy or lactation. Conclusions Redemption of broad-spectrum antibiotics during infancy is associated with an increased risk of childhood type 1 diabetes in children delivered by cesarean section. PMID:27560963

    Full Text Available BACKGROUND: Childhood tuberculosis (TB patients under India's Revised National TB Control Programme (RNTCP are managed using diagnostic algorithms and directly observed treatment with intermittent thrice-weekly short-course treatment regimens for 6-8 months. The assignment into pre-treatment weight bands leads to drug doses (milligram per kilogram that are lower than current World Health Organization (WHO guidelines for some patients. OBJECTIVES: The main aim of our study was to describe the baseline characteristics and treatment outcomes reported under RNTCP for registered childhood (age <15 years TB patients in Delhi. Additionally, we compared the reported programmatic treatment completion rates between children treated as per WHO recommended anti-TB drug doses with those children treated with anti-TB drug doses below that recommended in WHO guidelines. METHODS: For this cross-sectional retrospective study, we reviewed programme records of all 1089 TB patients aged <15 years registered for TB treatment from January to June, 2008 in 6 randomly selected districts of Delhi. WHO disease classification and treatment outcome definitions are used by RNTCP, and these were extracted as reported in programme records. RESULTS AND CONCLUSIONS: Among 1074 patients with records available, 651 (61% were females, 122 (11% were <5 years of age, 1000 (93% were new cases, and 680 (63% had extra-pulmonary TB (EP-TB--most commonly peripheral lymph node disease [310 (46%]. Among 394 pulmonary TB (PTB cases, 165 (42% were sputum smear-positive. The overall reported treatment completion rate was 95%. Similar reported treatment completion rates were found in all subgroups assessed, including those patients whose drug dosages were lower than that currently recommended by WHO. Further studies are needed to assess the reasons for the low proportion of under-5 years of age TB case notifications, address challenges in reaching all childhood TB patients by RNTCP, the

    Childhood obesity is an issue of serious medical and social concern. In developing countries including India, it is a phenomenon seen in higher socioeconomic strata due to the adoption of a western lifestyle. Consumption of high calorie food, lack of physical activity and increased screen time are major risk factors for childhood obesity apart from other genetic, prenatal factors and socio-cultural practices. Obese children and adolescents are at increased risk of medical and psychological complications. Insulin resistance is commonly present especially in those with central obesity and manifests as dyslipidemia, type 2 diabetes mellitus, impaired glucose tolerance, hypertension, polycystic ovarian syndrome and metabolic syndrome. Obese children and adolescents often present to general physicians for management. The latter play a key role in prevention and treatment of obesity as it involves lifestyle modification of the entire family. This article aims at discussing the approach to diagnosis and work-up, treatment and preventive strategies for childhood obesity from a general physician's perspective.

  2. Dexamethasone acts as a radiosensitizer in three astrocytoma cell lines via oxidative stress

    Full Text Available Glucocorticoids (GCs, which act on stress pathways, are well-established in the co-treatment of different kinds of tumors; however, the underlying mechanisms by which GCs act are not yet well elucidated. As such, this work investigates the role of glucocorticoids, specifically dexamethasone (DEXA, in the processes referred to as DNA damage and DNA damage response (DDR, establishing a new approach in three astrocytomas cell lines (CT2A, APP.PS1 L.1 and APP.PS1 L.3. The results show that DEXA administration increased the basal levels of gamma-H2AX foci, keeping them higher 4 h after irradiation (IR of the cells, compared to untreated cells. This means that DEXA might cause increased radiosensitivity in these cell lines. On the other hand, DEXA did not have an apparent effect on the formation and disappearance of the 53BP1 foci. Furthermore, it was found that DEXA administered 2 h before IR led to a radical change in DNA repair kinetics, even DEXA does not affect cell cycle. It is important to highlight that DEXA produced cell death in these cell lines compared to untreated cells. Finally and most important, the high levels of gamma-H2AX could be reversed by administration of ascorbic acid, a potent blocker of reactive oxygen species, suggesting that DEXA acts by causing DNA damage via oxidative stress. These exiting findings suggest that DEXA might promote radiosensitivity in brain tumors, specifically in astrocytoma-like tumors.

  3. Intensive Treatment with Ultrasound Visual Feedback for Speech Sound Errors in Childhood Apraxia

    2016-01-01

    Ultrasound imaging is an adjunct to traditional speech therapy that has shown to be beneficial in the remediation of speech sound errors. Ultrasound biofeedback can be utilized during therapy to provide clients with additional knowledge about their tongue shapes when attempting to produce sounds that are erroneous. The additional feedback may assist children with childhood apraxia of speech (CAS) in stabilizing motor patterns, thereby facilitating more consistent and accurate productions of sounds and syllables. However, due to its specialized nature, ultrasound visual feedback is a technology that is not widely available to clients. Short-term intensive treatment programs are one option that can be utilized to expand access to ultrasound biofeedback. Schema-based motor learning theory suggests that short-term intensive treatment programs (massed practice) may assist children in acquiring more accurate motor patterns. In this case series, three participants ages 10–14 years diagnosed with CAS attended 16 h of speech therapy over a 2-week period to address residual speech sound errors. Two participants had distortions on rhotic sounds, while the third participant demonstrated lateralization of sibilant sounds. During therapy, cues were provided to assist participants in obtaining a tongue shape that facilitated a correct production of the erred sound. Additional practice without ultrasound was also included. Results suggested that all participants showed signs of acquisition of sounds in error. Generalization and retention results were mixed. One participant showed generalization and retention of sounds that were treated; one showed generalization but limited retention; and the third showed no evidence of generalization or retention. Individual characteristics that may facilitate generalization are discussed. Short-term intensive treatment programs using ultrasound biofeedback may result in the acquisition of more accurate motor patterns and improved articulation

    A case of astrocytoma whose first clinical presentation was diagnostic dyspraxia was reported. A 38-year-old right-handed male experienced funny motion of his left hand triggered by voluntary movement of his right hand. One day, he tried to insert a coin into the vending machine with his right hand, then the left hand was against the other. One month after that event, he experienced headache and vertigo. On admission, there were no abnormal findings on neurological examination. On neuropsychological examination, he was cooperative, well orientated and attentive, and there were no callosal disconnection symptoms. Frontal lobe function tests were slightly impaired. T1-weighted MRI demonstrated irregular mixed signal intensity mass lesion extending from the genu to the body of the corpus callosum and the cingulate gyrus. This lesion was slightly enhanced with Gd-DTPA. Biopsy was performed and histological diagnosis was fibrillary astrocytoma. After irradiation and chemotherapy, he was discharged from the hospital without evident neurological deficit. About 20 cases of diagnostic dyspraxia have been reported and almost all of them were caused by cerebro-vascular disease. This is the first case of brain tumor who presented diagnostic dyspraxia.

  5. Antibiotic treatment for acute haematogenous osteomyelitis of childhood: moving towards shorter courses and oral administration.

    Acute haematogenous osteomyelitis (AHOM) of childhood usually affects the long bones of the lower limbs. Although almost any agent may cause AHOM, Staphylococcus aureus is the most common bacterium, followed by Streptococcus pneumoniae and, in some countries, Salmonella spp. and Kingella kingae. Magnetic resonance imaging (MRI) has improved the diagnostic accuracy of traditional radiography and scintigraphy. Except for the pre-treatment diagnostic sample from bone before the institution of antibiotic therapy, no other surgery is usually required. Traditionally, non-neonatal AHOM has been treated with a 1-3-month course of antibiotics, including an intravenous (i.v.) phase for the first weeks, but recent prospective randomised studies challenge this approach. For most uncomplicated cases, a course of 20 days including an i.v. period of 2-4 days suffices, provided large enough doses of a well-absorbed agent (clindamycin or a first-generation cephalosporin, local resistance permitting) are used, administration is four times daily and most symptoms and signs subside within a few days. Serum C-reactive protein (CRP) is a good guide in monitoring the course of illness, and the antimicrobial can usually be discontinued if CRP has decreased to <20 mg/L. Newer and costly agents, such as linezolid, should be reserved for cases due to resistant S. aureus strains. AHOM in neonates and immunocompromised patients probably requires a different approach. Because sequelae may develop slowly, follow-up for at least 1 year post hospitalisation is recommended.

    Purpose: Cancer in childhood may disrupt normal developmental processes and cause psychosocial problems in adolescent survivors of childhood cancers (ACCSs). Previous studies report inconsistent findings. Study aims were to assess subjective well-being (SWB), psychological distress, and school contentment in survivors of three dissimilar childhood cancers. Patients and methods: Nordic patients treated for acute myeloid leukemia (AML), infratentorial astrocytoma (IA), and Wilms tumor (WT) in childhood from 1985 to 2001, aged ≥1 year at diagnosis, and aged 13-18 years at the time of study were eligible for this questionnaire-based survey that included items on SWB, psychological distress, school contentment, self-esteem, and personality traits; 65% (151/231) responded. An age-equivalent group from a Norwegian health survey (n=7910) served as controls. Results: The median age of ACCSs was 16 years; 52% were males. ACCSs reported better SWB (p=0.004) and self-esteem (p<0.001). They had fewer social problems in school (p=0.004) and their school contentment tended to be higher than controls. SWB and school contentment were positively influenced by self-esteem. However, ACCSs reported higher levels of psychological distress (p=0.002), mostly attributable to general worrying. No significant differences in outcomes were found across diagnoses, and time since diagnosis did not significantly affect the results. Conclusion: The overall emotional functioning of ACCSs was good, possibly due to changes in their perception of well-being after having survived a life-threatening disease. However, they seemed more worried than their peers. This may cause an additional strain at a vulnerable period in life.

    Background Glial brain tumors cause considerable mortality and morbidity in children and adults. Innovative targets for therapy are needed to improve survival and reduce long-term sequelae. The aim of this study was to find a candidate tumor-promoting protein, abundantly expressed in tumor cells but not in normal brain tissues, as a potential target for therapy. Methods In silico proteomics and genomics, immunohistochemistry, and immunofluorescence microscopy validation were performed. RNA interference was used to ascertain the functional role of the overexpressed candidate target protein. Results In silico proteomics and genomics revealed pre-B-cell leukemia homeobox (PBX) interacting protein 1 (PBXIP1) overexpression in adult and childhood high-grade glioma and ependymoma compared with normal brain. PBXIP1 is a PBX-family interacting microtubule-binding protein with a putative role in migration and proliferation of cancer cells. Immunohistochemical studies in glial tumors validated PBXIP1 expression in astrocytoma and ependymoma but not in oligodendroglioma. RNAi-mediated PBXIP1-knockdown in glioblastoma cell lines strongly reduced proliferation and migration and induced morphological changes, indicating that PBXIP1 knockdown decreases glioma cell viability and motility through rearrangements of the actin cytoskeleton. Furthermore, expression of PBXIP1 was observed in radial glia and astrocytic progenitor cells in human fetal tissues, suggesting that PBXIP1 is an astroglial progenitor cell marker during human embryonic development. Conclusion PBXIP1 is a novel protein overexpressed in astrocytoma and ependymoma, involved in tumor cell proliferation and migration, that warrants further exploration as a novel therapeutic target in these tumors.

    2017-03-01

    Evidence of a high or increasing incidence of childhood onset bipolar disorder in the United States (US) has been viewed skeptically. Here we review evidence that childhood onsets of bipolar disorder are more common in the US than in Europe, treatment delays are longer, and illness course is more adverse and difficult. Epidemiological data and studies of offspring at high risk also support these findings. In our cohort of outpatients with bipolar disorder, two of the major vulnerability factors for early onset - genetics and environmental adversity in childhood - were also greater in the US than in Europe. An increased familial loading for multiple psychiatric disorders was apparent in 4 generations of the family members of the patients from the US, and that familial burden was linked to early onset bipolar disorder. Since both early onset and treatment delay are risk factors for a poor outcome in adulthood, new clinical, research, and public health initiatives are needed to begin to address and ameliorate this ongoing and potentially devastating clinical situation.

    2004-06-01

    Background: only few reports of effects of radiotherapy in childhood on the dental apparatus are available in the literature. The basis for early loss of teeth appears to be a reduction of the root surface area after radiation exposure. These effects in the periodontium are a consequence of combined radiochemotherapy usually applied for treatment of childhood neoplasia. Chemotherapy alone also results in changes of periodontal development. Case report: a 33-year-old patient is reported, who, at the age of 11 years, received high-dose chemotherapy and radiotherapy of neuroaxis and cranium for acute lymphatic leukemia with relapse. The patient consulted the Implant Section of the Department of Oral and Maxillofacial Surgery because of severe dental changes and tooth loss despite adequate dental care and oral hygiene. Radiation doses given to the superior maxilla and mandible at the age of 11 were estimated to be in the range of 8-25 Gy. Conclusion: intense, life-long dental care and follow-up of patients cured from malignant disease in childhood must hence be postulated in order to minimize dental treatment sequelae by supportive measures, but also to initiate timely adequate dental and prosthetic management.

    2012-12-01

    A 17-year-old, male castrated cougar (Puma concolor) was presented minimally responsive and severely depressed, with bilateral mydriasis and absent pupillary light response. On gross examination of the brain, there was a tan-to-gray, invasive mass with a central cavitation on the ventral aspect in the left cerebral hemisphere, rostral to the caudate nucleus. On histopathologic examination, the mass was composed of sheets of medium-sized, round-to-polygonal cells that were multifocally separated by islands of neuropil. Approximately 80% of the neoplastic cells showed strong cytoplasmic labeling for glial fibrillary acidic protein. These findings were consistent with a medium-grade astrocytoma. To the authors' knowledge, neoplastic disease of the central nervous system has not been previously reported in cougars.

    Full Text Available Histological classification and grading are prime procedures in the management of patients with astrocytoma, providing vital data for therapeutic decision making and prognostication. However, it has limitations in assessing biological tumor behavior. This can be overcome by using newer immunohistochemical techniques. This study was carried out to compare proliferative indices using proliferating cell nuclear antigen (PCNA, extent of p53 expression and micro vessel morphometric parameters in patients with low grade and anaplastic astrocytoma. Twenty-five patients, each of grade II and grade III astrocytoma were evaluated using monoclonal antibodies to PCNA, p53 protein and factor VIII related antigen. PCNA, p53-labeling indices were calculated along with micro vessel morphometric analysis using Biovis Image plus Software. Patients with grade III astrocytoma had higher PCNA and p53 labeling indices as compared with grade II astrocytoma (29.14 plus/minus 9.87% vs. 16.84 plus/minus 6.57%, p 0.001; 18.18 plus/minus 6.14% vs. 6.14 plus/minus 7.23%, p 0.001, respectively. Micro vessel percentage area of patients with grade III astrocytoma was also (4.26 plus/minus 3.70 vs. 1.05 plus/minus 0.56, p 0.001, higher along with other micro vessel morphometric parameters. Discordance between histology and one or more IHC parameters was seen in 5/25 (20% of patients with grade III astrocytoma and 9/25 (36% of patients with grade II disease. PCNA and p53 labeling indices were positively correlated with Pearson′s correlation, p less than 0.001 for both. Increased proliferative fraction, genetic alterations and neovascularization mark biological aggressiveness in astrocytoma. Immunohistochemical evaluation scores over meet the challenge of accurate prognostication of this potentially fatal malignancy.

    Full Text Available Stefin B (cystatin B is an endogenous inhibitor of cysteine proteinases localized in the nucleus and the cytosol. Loss-of-function mutations in the stefin B gene (CSTB gene were reported in patients with Unverricht-Lundborg disease (EPM1. Our previous results showed that thymocytes isolated from stefin B-deficient mice are more sensitive to apoptosis induced by the protein kinase C inhibitor staurosporin (STS than the wild-type control cells. We have also shown that the increased expression of stefin B in the nucleus of T98G astrocytoma cells delayed cell cycle progression through the S phase. In the present study we examined if the nuclear or cytosolic functions of stefin B are responsible for the accelerated induction of apoptosis observed in the cells from stefin B-deficient mice. We have shown that the overexpression of stefin B in the nucleus, but not in the cytosol of astrocytoma T98G cells, delayed caspase-3 and-7 activation. Pretreatment of cells with the pan-caspase inhibitor z-Val-Ala-Asp(OMe-fluoromethylketone completely inhibited caspase activation, while treatment with the inhibitor of calpains- and papain-like cathepsins (2S,3S-trans-epoxysuccinyl-leucylamido-3-methyl-butane ethyl ester did not prevent caspase activation. We concluded that the delay of caspase activation in T98G cells overexpressing stefin B in the nucleus is independent of cathepsin inhibition.

    Full Text Available Accumulating evidence supports the idea that secondary metabolites obtained from medicinal plants (phytometabolites may be important contributors in the development of new chemotherapeutic agents to reduce the occurrence or recurrence of cancer. Our study focused on Dehydroleucodine (DhL, a sesquiterpene found in the provinces of Loja and Zamora-Chinchipe. In this study, we showed that DhL displayed cytostatic and cytotoxic activities on the human cerebral astrocytoma D384 cell line. With lactone isolated from Gynoxys verrucosa Wedd, a medicinal plant from Ecuador, we found that DhL induced cell death in D384 cells by triggering cell cycle arrest and inducing apoptosis and DNA damage. We further found that the cell death resulted in the increased expression of CDKN1A and BAX proteins. A marked induction of the levels of total TP73 and phosphorylated TP53, TP73, and γ-H2AX proteins was observed in D384 cells exposed to DhL, but no increase in total TP53 levels was detected. Overall these studies demonstrated the marked effect of DhL on the diminished survival of human astrocytoma cells through the induced expression of TP73 and phosphorylation of TP73 and TP53, suggesting their key roles in the tumor cell response to DhL treatment.

    Pediatric midline high-grade astrocytomas (mHGAs) are incurable with few treatment targets identified. Most tumors harbor mutations encoding p.Lys27Met in histone H3 variants. In 40 treatment-naive mHGAs, 39 analyzed by whole-exome sequencing, we find additional somatic mutations specific to tumor location. Gain-of-function mutations in ACVR1 occur in tumors of the pons in conjunction with histone H3.1 p.Lys27Met substitution, whereas FGFR1 mutations or fusions occur in thalamic tumors associated with histone H3.3 p.Lys27Met substitution. Hyperactivation of the bone morphogenetic protein (BMP)-ACVR1 developmental pathway in mHGAs harboring ACVR1 mutations led to increased levels of phosphorylated SMAD1, SMAD5 and SMAD8 and upregulation of BMP downstream early-response genes in tumor cells. Global DNA methylation profiles were significantly associated with the p.Lys27Met alteration, regardless of the mutant histone H3 variant and irrespective of tumor location, supporting the role of this substitution in driving the epigenetic phenotype. This work considerably expands the number of potential treatment targets and further justifies pretreatment biopsy in pediatric mHGA as a means to orient therapeutic efforts in this disease.

  1. Biochemical Signatures of Doppel Protein in Human Astrocytomas to Support Prediction in Tumor Malignancy

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Doppel (Dpl is a membrane-bound glycoprotein mainly expressed in the testis of adult healthy people. It is generally absent in the central nervous system, but its coding gene sequence is ectopically expressed in astrocytoma specimens and in derived cell lines. In this paper, we investigated the expression and the biochemical features of Dpl in a panel of 49 astrocytoma specimens of different WHO malignancy grades. As a result, Dpl was expressed in the majority of the investigated specimens (86%, also including low grade samples. Importantly, Dpl exhibited different cellular localizations and altered glycan moieties composition, depending on the tumor grade. Most low-grade astrocytomas (83% showed a membrane-bound Dpl, like human healthy testis tissue, whereas the majority of high-grade astrocytomas (75% displayed a cytosolic Dpl. Deglycosylation studies with N-glycosidase F and/or neuraminidase highlighted defective glycan moieties and an unexpected loss of sialic acid. To find associations between glial tumor progression and Dpl biochemical features, predictive bioinformatics approaches were produced. In particular, Decision tree and Nomogram analysis showed well-defined Dpl-based criteria that separately clustered low-and high-grade astrocytomas. Taken together, these findings show that in astrocytomas, Dpl undergoes different molecular processes that might constitute additional helpful tools to characterize the glial tumor progression.

  8. Enlarged piloid astrocytoma of the midbrain: recurrence or pseudoprogression? A clinical case

    Directory of Open Access Journals (Sweden)

    Yu. Yu. Trunin

    2016-01-01

    Full Text Available Piloid astrocytoma (PA is a glioma that is most frequently encountered in children (WHO grade I. According to most authors, stereotactic radiation (radiotherapy and radiosurgery is an effective method to control tumor growth in patients with incomplete removal of PA and its recurrence. The authors describe a clinical case of a female patient with PA of the midbrain; during the first 7 months after radiation she showed an obvious enlargement of the tumor, as evidenced by magnetic resonance imaging (MRI, with its further regression without any antitumor treatment. A follow-up of the patient and a regular evaluation of her clinical status and MRI changes, as compared to the similar clinical cases and literature data, may suggest that PA enlargement early after radiotherapy is generally pseudoprogression rather than true progression of the tumor. An understanding of this phenomenon will be able to improve the assessment of radiotherapy results in patients with PA and to rule out unnecessary antitumor treatment in this category of patients.

    Even low-grade astrocytomas infiltrate the entire brain, a feature that precludes their successful therapy. So to assess the invasive potential of astrocytoma is very important. The aim of this study was determine whether there is a significant correlation between the results of {sup 1}H-magnetic resonance spectroscopy ({sup 1}H-MRS) and tumor invasive potential of astrocytoma, which is reflected by expression of matrix metalloproteinase-2 (MMP-2). The {sup 1}H-MRS spectra of 41 histologically verified astrocytomas were obtained on a 3-T MR scanner. According to the World Health Organization classification criteria for central nervous system tumors, there were 16 low-grade astrocytomas (2 pilocytic astrocytomas, 14 grade II astrocytomas) and 25 high-grade astrocytomas (5 anaplastic astrocytomas, 20 glioblastomas).The choline/N-acetylaspartate (Cho/NAA) and choline/creatine (Cho/Cr) ratios were calculated. Of the 41 astrocytomas, 19 (8 low-grade and 11 high-grade) were analyzed immunohistochemically. Expression of MMP-2 was determined using streptavidin-peroxidase complex (SP) staining which was quantified by calculating its calibrated opacity density (COD) using an image analysis system. The correlations between metabolite ratios and the quantitative data from the immunohistochemical tests in the 19 astrocytomas were determined. The Cho/NAA and Cho/Cr ratios of high-grade astrocytoma were both significantly greater than those of low-grade astrocytoma (t = -6.222, P = 0.000; t = -6.533, P = 0.000, respectively). MMP-2 COD values of high-grade astrocytomas were also significantly greater than those of low-grade astrocytomas (t = -5.892, P = 0.000). There were strong positive correlations between Cho/NAA ratio and MMP-2 COD (r = 0.669, P = 0.002), and between Cho/Cr ratio and MMP-2 COD (r = 0.689, P = 0.001). {sup 1}H-MRS is helpful in evaluating the invasiveness of astrocytomas and predicting prognosis preoperatively by determining the Cho/NAA and Cho/Cr ratios

    Full Text Available Background: Recent studies have confirmed that alterations in the isoenzyme of pyruvate kinase (PK provide tumor cells with selective growth advantage. Aims: Our aim was to establish the mean activity of the enzyme PK in human astrocytomas and to look for any trends in the activity with relation to histological grade. Materials and Methods: The PK (EC 2.7.1.40 activity was measured in the tumor homogenate by spectrophotometric rate determination. ΔAbsorbance at 340 nm (A 340nm per minute was obtained using the maximal linear rate for both the test and the blank. Enzyme activity was estimated in the presence and absence of amino acid alanine. Results: The mean PK level in astrocytomas was 3.5 ± 2.0 mmol/min/mg protein, which was significantly higher (24%; P < 0.001 when compared to 2.8 ± 0.3 mmol/min/mg protein in control brain. Highest PK activity was noted in grade 2 astrocytomas. In controls there was no change in PK activity in the presence of alanine. In grade 2 astrocytomas there was 7% decrease in mean PK activity in the presence of alanine, this difference in grade 3 astrocytomas was 33% and in grade 4 astrocytomas it was 61%. As the tumors were becoming malignant there was a graded increase in the levels of PK inhibition. Conclusions: Mean PK activity was significantly higher in astrocytomas. There was a graded increase in level of PK inhibition as the tumors were becoming more malignant.

  11. Zinc and childhood infections: From the laboratory to new treatment recommendations

    2009-10-01

    Full Text Available Zinc is an essential nutrient particularly important for growing children and for those who experience frequent infections. Many children in developing countries have inadequate zinc nutrition that impairs their immune system. Diarrhea and pneumonia are among the leading causes of morbidity and mortality in children of low-income countries. Zinc deficiency increases the susceptibility to these infections and administration of zinc to children with diarrhea and, possibly, pneumonia speeds up recovery. Furthermore, zinc given to otherwise healthy children also reduces the incidence of diarrhea and pneumonia. Thus, thousands of lives can be saved every year by giving zinc to prevent childhood infections or by providing zinc to children with ongoing infections. This paper gives a brief outline of the history of zinc research and reviews existing evidence from clinical trials on the prophylactic and therapeutic effect of oral zinc on childhood pneumonia and diarrhea

    Full text: The histopathological grade and radiological appearance of the diverse cerebral neoplasms in childhood frequently poorly reflect their biological behaviour. We examined thallium accumulation prior to treatment (and in several cases, at intervals there after) in 13 children to determine its usefulness as a tumour marker. 23 SPECT studies were acquired 20 minutes after the injection of 1-3 mCi of {sup 201}TI. Thallium index (TI), the ratio of counts in tumour/normal brain, was calculated. No uptake was seen in two patients (pts) with a Grade 1 cerebellar astrocytomas (disease free at 4/12 f/u). Three pts with medulloblastomas were studied. One pt showed intense uptake (Tl =12). His tumour (proliferative antigen stain Ki67 = 50%) recurred early after debulking surgery (Tl +ve prior to CT or MRI changes). The second pt was imaged at relapse (Ki67 = 60%) and showed intense uptake, Tl = 17. The third pt showed lower level uptake (Tl = 2), Ki67 = 5%, and is disease-free at 5/12 (as per {sup 201}TI and MRI). One pt with a Grade 1 brainstem glioma showed Tl = 5 and has progressed rapidly despite low grade histology. Four pts with chiasmatic-hypothalamic gliomas have been studied. Although these neoplasms are usually low grade histologically, their growth properties vary greatly. Two pts with Tl<2.5 have been conservatively managed because of slow tumour growth. The other two pts have Tl>3.5 and have required aggressive treatment for rapid disease progression. One pt with a large pilocytic astrocytoma of the optic chiasm showed Tl = 9.5. Active treatment was not undertaken. One pt with a pineal germ cell tumour showed avid {sup 201}TI uptake (Tl not performed) and has had two normal studies, and is clinically well, since BMT. Avid {sup 201}TI uptake also seen in one pt with cerebral neuroblastoma. (Died at 8/12 after Dx.) Thus, {sup 201}TI accumulates in histologically diverse paediatric neoplasms. The Tl appears to reflect biological behaviour in the limited

    2012-08-01

    Full Text Available Abstract Background Childhood Apraxia of Speech is an impairment of speech motor planning that manifests as difficulty producing the sounds (articulation and melody (prosody of speech. These difficulties may persist through life and are detrimental to academic, social, and vocational development. A number of published single subject and case series studies of speech treatments are available. There are currently no randomised control trials or other well designed group trials available to guide clinical practice. Methods/Design A parallel group, fixed size randomised control trial will be conducted in Sydney, Australia to determine the efficacy of two treatments for Childhood Apraxia of Speech: 1 Rapid Syllable Transition Treatment and the 2 Nuffield Dyspraxia Programme – Third edition. Eligible children will be English speaking, aged 4–12 years with a diagnosis of suspected CAS, normal or adjusted hearing and vision, and no comprehension difficulties or other developmental diagnoses. At least 20 children will be randomised to receive one of the two treatments in parallel. Treatments will be delivered by trained and supervised speech pathology clinicians using operationalised manuals. Treatment will be administered in 1-hour sessions, 4 times per week for 3 weeks. The primary outcomes are speech sound and prosodic accuracy on a customised 292 item probe and the Diagnostic Evaluation of Articulation and Phonology inconsistency subtest administered prior to treatment and 1 week, 1 month and 4 months post-treatment. All post assessments will be completed by blinded assessors. Our hypotheses are: 1 treatment effects at 1 week post will be similar for both treatments, 2 maintenance of treatment effects at 1 and 4 months post will be greater for Rapid Syllable Transition Treatment than Nuffield Dyspraxia Programme treatment, and 3 generalisation of treatment effects to untrained related speech behaviours will be greater for Rapid

  14. Sudden losses and sudden gains during a DBT-PTSD treatment for posttraumatic stress disorder following childhood sexual abuse

    Directory of Open Access Journals (Sweden)

    Antje Krüger

    2014-09-01

    Full Text Available Background: Exposure-based treatment approaches are first-line interventions for patients suffering from posttraumatic stress disorder (PTSD. However, the dissemination of exposure-based treatments for PTSD is challenging, as a large proportion of clinicians report being concerned about symptoms worsening as a result of this type of intervention and are therefore reluctant to offer it to patients with PTSD. However, there is only little empirical evidence to date on the pattern of symptom worsening during exposure-based treatment for PTSD. Objective: The goal of the present study was to explore the frequency of sudden losses and sudden gains in the course of an exposure-based treatment programme for female patients suffering from PTSD related to childhood sexual abuse who also show severe comorbidity. In addition, the relationship between sudden changes and treatment outcome was examined. Methods: Female participants (N=74 were randomised to either a 12-week residential DBT-PTSD programme or a treatment-as-usual wait list. The pattern of symptom change was assessed via weekly assessments using the Posttraumatic Diagnostic Scale (PDS. Sudden changes were computed as suggested by the literature on sudden gains. Results: During treatment, only one participant (3% experienced a sudden loss, whereas 25% of participants experienced sudden gains. In the waiting condition, 8% of the participants experienced sudden losses and 5% experienced sudden gains during the same time period. No symptom worsening was observed in response to exposure sessions. However, sudden gains occurred during exposure and non-exposure treatment weeks. Patients with sudden gains showed better treatment outcome in the post-treatment and follow-up assessments. Conclusions: Exposure-based treatment did not lead to PTSD symptom worsening in the study sample. Results show that sudden gains occur frequently during PTSD treatment and have a prognostic value for treatment outcome.

    2015-01-01

    The intensified administration of chemotherapeutic drugs has gradually replaced cranial radiation therapy (CRT) for the treatment of childhood acute lymphoblastic leukemia (ALL). While CRT is often implicated in neurocognitive impairment in ALL survivors, there is a paucity of literature that evaluates the persistence of neurocognitive deficits in long-term survivors of pediatric ALL who were treated with contemporary chemotherapy-only protocols. Results from this systematic review concurred to the probable cognitive-sparing effect of chemotherapy-based protocols over CRT in long-term survivors. However, coupled with multiple intrinsic and extrinsic factors, survivors who received chemotherapy treatment still suffered from apparent cognitive impairment, particularly in the attention and executive function domains. Notably, there is evidence to suggest that the late neurotoxic effect of methotrexate on survivors’ neurocognitive performance may be dose-related. This review also recommends future pharmacokinetic, neuroimaging and genetic studies to illuminate the multifactorial nature of this subject matter and discusses the potential value of neurochemical, physiological, inflammatory and genetic markers for the prediction of susceptibility to neurocognitive impairment in long-term survivors of childhood ALL.

    Full Text Available Objective:Constipation is a common problem in children. There is some clinical evidence for the role of probiotics and prebiotics in the treatment of constipated children. This is the first study on the therapeutic effect of synbiotics (combination of probiotics and prebiotic in treatment of childhood constipation. Methods:In a double-blind randomized placebo controlled study 102 children aged 4-12 years with functional constipation were assessed according to Rome III criteria for 4 weeks. They were divided into 3 groups: Group A, received 1.5 ml/kg/day oral liquid paraffin plus placebo, group B, 1 sachet synbiotic per day plus placebo and group C, 1.5 ml/kg/day oral liquid paraffin plus 1 sachet synbiotic per day. Frequency of bowel movements (BMs, stool consistency, number of fecal incontinence episodes, abdominal pain, painful defecation per week, success of treatment and side effects were determined in each group before and after treatment. Findings:The frequency of BMs per week increased in all groups (P<0.001, but it differed between groups and was higher in group C (P=0.03. Stool consistency increased and number of fecal incontinence episodes, abdominal pain and painful defecation per week decreased in all groups similarly and there was statistically no difference between them. No side effects were reported in group B; the main side effect in group A and C was seepage of oil (P<0.001. Treatment success was similar in all groups without any significant difference between them (P=0.6.   Conclusion:This study showed that synbiotics have positive effects on symptoms of childhood constipation without any side effects.

    A case of anaplastic astrocytoma following radiotherapy for growth hormone secreting pituitary adenoma is presented with a review of the literature. A 43 year old female was admitted with signs of acromegaly and hypertension. An eosinophilic pituitary adenoma was subtotally removed by transsphenoidal approach, followed by 60 Gy irradiation using a 2x2 cm lateral field. Fourteen years later at the age of 57, she suffered from headache, recent-memory disturbance and uncinate fits. CT scan and MRI disclosed ring-like enhanced mass lesion in the left temporal lobe, corresponding to the previous irradiated field. {sup 18}F-FDG PET showed hypermetabolism at the lesion. Left frontotemporal craniotomy was performed, and a reddish gray gelatinous tumor containing necrotic center and cyst was partially removed. Histologically, the tumor consisted of hypercellular astrocytic cells with perivascular pseudorosette. Coagulation necrosis at the center of the tumor, and hyalinosis and fibrosis of the blood vessels in and around the tumor, which might have been caused by the antecedent radiotherapy, were recognized. Postoperative radiotherapy and chemotherapy, were given, however, she expired 13 months after the operation. Seven cases, including ours, of malignant glioma following radiotherapy for pituitary adenoma were reported in the literature. A total dose of irradiation varies from 45 to 95 Gy with a mean of 50 Gy. The period of latency before tumor occurrence ranges from 5 to 22 years with a mean of 10 years. The differentiation of radiation-induced gliomas from radionecrosis of the brain is also discussed. (author).

    Full Text Available NTRODUCTION: Tuberous sclerosis complex (TSC or Morbus Bourneville - Pringle disease is an autosomal dominant phakomatosis, first described by Desiree - Magloire Bourneville in 1880. Tuberous sclerosis is a genetic disorder characterized by the growth of numerous benign tumours in many parts of the body caused by mutations on either of two genes, TSC1 and TSC2. This rare genetic disorder is usually associated with a triad of seizures, mental retardation and cutaneous lesions. Approximately one half of all patients affected by TS develop at least one retinal astrocytoma in one eye. PRESENTATION OF CASES: In the department of ophthalmology, G.S.L M edical C ollege, Rajahmundry, we came across 3 cases of tuberous sclerosis involving multi organ systems. Out of 3 cases, 2 cases were reported to be familial and 1case is sporadic, with a history of epilepsy with angiofibromatosis lesions over the face, multiple ash - leaf lesions over the abdomen, renal angiomyolipomas, multiple subependymal nodules in brain and retinal astrocytic hamartomas in the retina. CONCLUSION: It is important to be cognizant of the likely presence of systemic and ocular pathology in a child with mental retardation and skin lesions. Identification of retinal phakomatosis during ocular evaluation in any suspected case of Tuberous sclerosis can aid in the establishment of the diagnosis of the disease

    The brain depends on both glycolysis and mitochondrial oxidative phosphorylation for maintenance of ATP pools. Astrocytes play an integral role in brain functions providing trophic supports and energy substrates for neurons. In this paper, we report that human astrocytoma cells (ADF) undergoing ischemic conditions may use both purine and pyrimidine nucleosides as energy source to slow down cellular damage. The cells are subjected to metabolic stress conditions by exclusion of glucose and incubation with oligomycin (an inhibitor of oxidative phosphorylation). This treatment brings about a depletion of the ATP pool, with a concomitant increase in the AMP levels, which results in a significant decrease of the adenylate energy charge. The presence of purine nucleosides in the culture medium preserves the adenylate energy charge, and improves cell viability. Besides purine nucleosides, also pyrimidine nucleosides, such as uridine and, to a lesser extent, cytidine, are able to preserve the ATP pool. The determination of lactate in the incubation medium indicates that nucleosides can preserve the ATP pool through anaerobic glycolysis, thus pointing to a relevant role of the phosphorolytic cleavage of the N-glycosidic bond of nucleosides which generates, without energy expense, the phosphorylated pentose, which through the pentose phosphate pathway and glycolysis can be converted to energetic intermediates also in the absence of oxygen. In fact, ADF cells possess both purine nucleoside phosphorylase and uridine phosphorylase activities.

    Secreted frizzled-related protein 3 (SFRP3) is a member of the family of soluble proteins, which modulate the Wnt signaling cascade. Novel research has identified aberrant expression of SFRPs in different types of cancer. In the present study the expression intensities and localizations of the SFRP3 protein across different histopathological grades of astrocytic brain tumors were investigated by immunohistochemistry, digital scanning and image analysis. The results demonstrated that the differences between expression levels and malignancy grades were statistically significant. Tumors were classified into four malignancy grades according to the World Health Organization guidelines. Moderate (P=0.014) and strong (P=0.028) nuclear expression levels were significantly different in pilocytic (grade I) and diffuse (grade II) astrocytomas demonstrating higher expression values, as compared with anaplastic astrocytoma (grade III) and glioblastoma (grade IV). When the sample was divided into two groups, the moderate and high cytoplasmic expression levels were observed to be significantly higher in glioblastomas than in the group comprising astrocytoma II and III. Furthermore, the results indicated that high grade tumors were associated with lower values of moderate (P=0.002) and strong (P=0.018) nuclear expression in comparison to low grade tumors. Analysis of cytoplasmic staining demonstrated that strong cytoplasmic expression was significantly higher in the astrocytoma III and IV group than in the astrocytoma I and II group (P=0.048). Furthermore, lower grade astrocytomas exhibited reduced membranous SFRP3 staining when compared with higher grade astrocytomas and this difference was statistically significant (P=0.036). The present results demonstrated that SFRP3 protein expression levels were decreased in the nucleus in higher grade astrocytoma (indicating the expected behavior of an antagonist of Wnt signaling), whereas when the SFRP3 was located in the cytoplasm an

    Purpose To determine rates, patterns, and predictors of neurocognitive impairment in adults decades after treatment for childhood acute lymphoblastic leukemia (ALL). Patients and Methods Survivors of childhood ALL treated at St Jude Children's Research Hospital who were still alive at 10 or more years after diagnosis and were age ≥ 18 years were recruited for neurocognitive testing. In all, 1,014 survivors were eligible, 738 (72.8%) agreed to participate, and 567 (76.8%) of these were evaluated. Mean age was 33 years; mean time since diagnosis was 26 years. Medical record abstraction was performed for data on doses of cranial radiation therapy (CRT) and cumulative chemotherapy. Multivariable modeling was conducted and glmulti package was used to select the best model with minimum Akaike information criterion. Results Impairment rates across neurocognitive domains ranged from 28.6% to 58.9%, and those treated with chemotherapy only demonstrated increased impairment in all domains (all P values < .006). In survivors who received no CRT, dexamethasone was associated with impaired attention (relative risk [RR], 2.12; 95% CI, 1.11 to 4.03) and executive function (RR, 2.42; 95% CI, 1.20 to 4.91). The impact of CRT was dependent on young age at diagnosis for intelligence, academic, and memory functions. Risk for executive function problems increased with survival time in a CRT dose-dependent fashion. In all survivors, self-reported behavior problems increased by 5% (RR, 1.05; 95% CI, 1.01 to 1.09) with each year from diagnosis. Impairment was associated with reduced educational attainment and unemployment. Conclusion This study demonstrates persistent and significant neurocognitive impairment in adult survivors of childhood ALL and warrants ongoing monitoring of brain health to facilitate successful adult development and to detect early onset of decline as survivors mature.

    Glial fibrillary acidic protein (GFAP) is an intermediate filament protein expressed in astrocytes and neural stem cells. The GFAP gene is alternatively spliced, and expression of GFAP is highly regulated during development, on brain damage, and in neurodegenerative diseases. GFAPα is the canonical splice variant and is expressed in all GFAP-positive cells. In the human brain, the alternatively spliced transcript GFAPδ marks specialized astrocyte populations, such as subpial astrocytes and the neurogenic astrocytes in the human subventricular zone. We here show that shifting the GFAP isoform ratio in favor of GFAPδ in astrocytoma cells, by selectively silencing the canonical isoform GFAPα with short hairpin RNAs, induced a change in integrins, a decrease in plectin, and an increase in expression of the extracellular matrix component laminin. Together, this did not affect cell proliferation but resulted in a significantly decreased motility of astrocytoma cells. In contrast, a down-regulation of all GFAP isoforms led to less cell spreading, increased integrin expression, and a >100-fold difference in the adhesion of astrocytoma cells to laminin. In summary, isoform-specific silencing of GFAP revealed distinct roles of a specialized GFAP network in regulating the interaction of astrocytoma cells with the extracellular matrix through laminin.-Moeton, M., Kanski, R., Stassen, O.

    Full Text Available Aims: To analyze the impact of two cancer support groups in the treatment and abandonment of childhood cancer. Materials and Methods: This is a retrospective review of children with cancer funded and non-funded who were treated at Kanchi Kamakoti CHILDS Trust Hospital from 2010 to 2013. A total of 100 patients were funded, 57 by Ray of Light Foundation and 43 by Pediatric Lymphoma Project and 70 non-funded. Results: The total current survival of 80%, including those who have completed treatment and those currently undergoing treatment, is comparable in both the groups. Abandonment of treatment after initiating therapy was not seen in the financially supported group whereas abandonment of treatment after initiation was seen in one child in the non-funded group. Conclusions: Besides intensive treatment with good supportive care, financial support also has an important impact on compliance and abandonment in all socioeconomic strata of society. Financial support from private cancer support groups also has its impact beyond the patient and family, in reducing the burden on government institutions by non-governmental funding in private sector. Improvement in the delivery of pediatric oncology care in developing countries could be done by financial support from the private sector.

    A patient with neurofibromatosis type I (NF1) was followed-up with serial magnetic resonance imaging (MRI) studies over a period of 6 years. A contrast-enhancing lesion of the internal capsule, histologically proven to be pilocytic astrocytoma through stereotactic brain biopsy with mass effect and associated edema, was detected to reveal spontaneous involution on follow-up MRI studies. Although spontaneous regression of gliomas of the optic pathway-hypothalamus in patients with NF1 is relatively common in the literature, spontaneous involution of non-optic (i.e. areas other than optic pathways and hypothalamus) gliomas is rarely reported. Conservative management with follow-up MRI studies should be considered for non-optic glial tumors and tumor-like masses in patients with NF1, and surgical treatment should not be considered unless the lesions exhibit a rapid or unrelenting growth on serial MRI studies or produce significant clinical deterioration.

    Immunohistochemistry is an important tool that is often used for the diagnosis of pathologies; however, the length of time required to process the tissue is relatively long. Furthermore, the quality and sensitivity of immunohistochemical staining is affected by formalin fixation which results in variable loss of antigenicity, known as masking effect. Here we assess the effect of microwave irradiation on the incubation time required to obtain high quality immunohistochemical staining for cox-2 using archival formalin-fixed, paraffin-embedded human oligodendrogliomas and astrocytomas. The results show that intermittent microwave irradiation during the incubation with the primary antibody reduced the time requirement to 5 min while the staining quality was indistinguishable from 1 or 24 h long incubations. Thus, the use of this procedure results in a significant saving of time which is important for a timely diagnosis of pathological conditions that await treatment.

    Purpose Recent genome-wide screens have identified genetic variations in ARID5B associated with susceptibility to childhood acute lymphoblastic leukemia (ALL). We sought to determine the contribution of ARID5B single nucleotide polymorphisms (SNPs) to racial disparities in ALL susceptibility and treatment outcome. Patients and Methods We compared the association between ARID5B SNP genotype and ALL susceptibility in whites (> 95% European genetic ancestry; 978 cases and 1,046 controls) versus in Hispanics (> 10% Native American ancestry; 330 cases and 541 controls). We determined the relationships between ARID5B SNP genotype and ALL relapse risk in 1,605 children treated on the Children's Oncology Group (COG) P9904/9905 clinical trials. Results Among 49 ARID5B SNPs interrogated, 10 were significantly associated with ALL susceptibility in both whites and Hispanics (P < .05), with risk alleles consistently more frequent in Hispanics than in whites. rs10821936 exhibited the most significant association in both races (P = 8.4 × 10−20 in whites; P = 1 × 10−6 in Hispanics), and genotype at this SNP was highly correlated with local Native American genetic ancestry (P = 1.8 × 10−8). Multivariate analyses in Hispanics identified an additional SNP associated with ALL susceptibility independent of rs10821936. Eight ARID5B SNPs were associated with both ALL susceptibility and relapse hazard; the alleles related to higher ALL incidence were always linked to poorer treatment outcome and were more frequent in Hispanics. Conclusion ARID5B polymorphisms are important determinants of childhood ALL susceptibility and treatment outcome, and they contribute to racial disparities in this disease. PMID:22291082

    Full Text Available Abstract Background Diarrhoea disease which has been attributed to poverty constitutes a major cause of morbidity and mortality in children aged five and below in most low-and-middle income countries. This study sought to examine the contribution of individual and neighbourhood socio-economic characteristics to caregiver's treatment choices for managing childhood diarrhoea at household level in sub-Saharan Africa. Methods Multilevel multinomial logistic regression analysis was applied to Demographic and Health Survey data conducted in 11 countries in sub-Saharan Africa. The unit of analysis were the 12,988 caregivers of children who were reported to have had diarrhoea two weeks prior to the survey period. Results There were variability in selecting treatment options based on several socioeconomic characteristics. Multilevel-multinomial regression analysis indicated that higher level of education of both the caregiver and that of the partner, as well as caregivers occupation were associated with selection of medical centre, pharmacies and home care as compared to no treatment. In contrast, caregiver's partners' occupation was negatively associated with selection medical centre and home care for managing diarrhoea. In addition, a low-level of neighbourhood socio-economic disadvantage was significantly associated with selection of both medical centre and pharmacy stores and medicine vendors. Conclusion In the light of the findings from this study, intervention aimed at improving on care seeking for managing diarrhoea episode and other childhood infectious disease should jointly consider the influence of both individual SEP and the level of economic development of the communities in which caregivers of these children resides.

    Clinically significant separation anxiety disorder in childhood leads to adult panic disorder and other anxiety disorders. The prevailing pathophysiological model of anxiety disorders, which emphasizes extinction deficits of fear-conditioned responses, does not fully consider the role of separation anxiety. Pathological early childhood attachments have far-reaching consequences for the later adult ability to experience and internalize positive relationships in order to develop mental capacities for self-soothing, anxiety tolerance, affect modulation, and individuation. Initially identified in attachment research, the phenomenon of separation anxiety is supported by animal model, neuroimaging, and genetic studies. A role of oxytocin is postulated. Adults, inured to their anxiety, often do not identify separation anxiety as problematic, but those who develop anxiety and mood disorders respond more poorly to both pharmacological and psychotherapeutic interventions. This poorer response may reflect patients' difficulty in forming and maintaining attachments, including therapeutic relationships. Psychotherapies that focus on relationships and separation anxiety may benefit patients with separation anxiety by using the dyadic therapist-patient relationship to recapture and better understand important elements of earlier pathological parent-child relationships.

    The management of optic chiasmatic gliomas is controversial, partly related to failure to separate out those tumors involving the optic chiasm only (chiasmatic tumors) from those also involving the hypothalamus (chiasmatic/hypothalamic tumors). The purpose of this study was: (i) to analyze the outcomes of chiasmatic and chiasmatic/hypothalamic tumors separately; and (ii) to determine the appropriateness of recommending radical surgical resection for the chiasmatic/hypothalamic tumors. A retrospective chart review of all newly diagnosed tumors involving the optic chiasm from 1982-1996 at British Columbia's Children's Hospital was performed. There were 32 patients less than 16 years of age, 14 with chiasmatic and 18 with chiasmatic/hypothalamic astrocytomas, with an average duration of follow-up of 5.8 years and 6.3 years, respectively. Ten of the patients with chiasmatic tumors and none with chiasmatic/hypothalamic tumors had neurofibromatosis I. Thirteen of the 14 chiasmatic tumors were managed with observation only, and none had progression requiring active intervention. For the chiasmatic/hypothalamic tumors. eight patients had subtotal resections (>95% resection), six had partial resections (50-95%), three had limited resections (<50%), and one had no surgery. There were fewer complications associated with the limited resections, especially with respect to hypothalamic dysfunction. There was no correlation between the extent of resection (subtotal, partial, or limited) and the time to tumor progression (average 18 months). In conclusion, chiasmatic and chiasmatic/hypothalamic tumors are different entities, which should be separated out for the Purposes of any study. For the chiasmatic/hypothalamic tumors, there was more morbidity and no prolongation of time to progression when radical resections were compared to more limited resections. Therefore, if surgery is performed, it may be appropriate to do a surgical procedure that strives only to provide a

    Pilomyxoid astrocytoma (PMA) is a recently described tumor typically occurring in the hypothalamic-chiasmatic region of very young children. PMA is characterized by a more aggressive course than pilocytic astrocytoma and exhibits certain differing histological features. We report a PMA in an adolescent patient with visual field disturbance. Imaging studies revealed enlargement of the sella turcica due to a homogenously enhancing sellar and suprasellar mass identifiable both on CT scans and MRI. We believe that PMA may be included in the list of differential diagnoses of the lesions expanding the sella turcica.

    Full Text Available The history of treatment of childhood leukemia is a meaningful model of ethical, bioethical and organizational repercussions of medical progress. Specifically, it has provided precious indications and very useful tools to cope with several of the more important problems of modern medicine: the value of controlled randomized studies; the risks of intense medicalization impairing the quality of care; the importance of a valid doctor-patient relationship; the psycho-emotive involvement of the pediatric staff; and last but not least, the need of an unrelenting effort of humanization of the procedures and environments, hand in hand with the frequent adjustments of the protocols according to scientific and technological progress. Finally, the authors comment upon the first cures (1962-1966 observed in the Pediatrics Clinic of the Sapienza University of Rome.

    Juvenile scleroderma is a rare connective tissue disease that involves the skin and subcutaneous tissue. Among all presentations of juvenile scleroderma, localized scleroderma (JLSc) is the most frequent, followed by systemic disease (JSSc) and eosinophilic fasciitis (EF). In posttransplantation chronic graft-versus-host disease (GvHD), scleroderma-like skin involvement can occur. Systemic forms of juvenile scleroderma and GvHD can affect the internal organs, such as the lungs, the gastrointestinal tract, the heart, and kidneys and cause disability and severe, sometimes lethal, complications. Here, the authors give an overview of different presentations of juvenile scleroderma. They report their experience with the different forms and presentations of scleroderma, diagnostic workups, treatment, and outcome of all forms of childhood scleroderma in the context of the existing literature.

    Survival rates have been excellent in patients treated for Hodgkin lymphoma (HL) during childhood and adolescence. Unfortunately, severe treatment related late effects have been observed. It was therefore an important aim of the cooperative pediatric HL therapy studies in Germany to reduce the number of late effects without jeopardizing the excellent treatment results. Progress and relapses of HL were analyzed to obtain important information for the future salvage therapy. All late effects were documented and their etiologies analyzed. Information obtained from bacterial infections and late deaths following splenectomy were used to inform patients at risk and their local physicians about necessary preventive measurements. Procarbazine was recognized as major gonadotoxic agent in boys and eliminated successively from the treatment regimens. Parenthood was normal in female patients when compared to the German female population documenting normal ovarian function except in patients with pelvic radiation. Radiation was the most important risk factor for thyroid diseases, cardiac late effects and subsequent malignant neoplasms, especially thyroid and breast cancer. A special screening program was initiated for women with chest radiotherapy, since they had a high risk of breast cancer already at a young age. The results of the HL Late Effects Research Project are important for the aftercare of patients and for the design of future HL treatment regimens.

    2011-07-01

    Full Text Available Abstract Background Pilocytic Astrocytomas (PAs are common low-grade central nervous system malignancies for which few recurrent and specific genetic alterations have been identified. In an effort to better understand the molecular biology underlying the pathogenesis of these pediatric brain tumors, we performed higher-order transcriptional network analysis of a large gene expression dataset to identify gene regulatory pathways that are specific to this tumor type, relative to other, more aggressive glial or histologically distinct brain tumours. Methods RNA derived from frozen human PA tumours was subjected to microarray-based gene expression profiling, using Affymetrix U133Plus2 GeneChip microarrays. This data set was compared to similar data sets previously generated from non-malignant human brain tissue and other brain tumour types, after appropriate normalization. Results In this study, we examined gene expression in 66 PA tumors compared to 15 non-malignant cortical brain tissues, and identified 792 genes that demonstrated consistent differential expression between independent sets of PA and non-malignant specimens. From this entire 792 gene set, we used the previously described PAP tool to assemble a core transcriptional regulatory network composed of 6 transcription factor genes (TFs and 24 target genes, for a total of 55 interactions. A similar analysis of oligodendroglioma and glioblastoma multiforme (GBM gene expression data sets identified distinct, but overlapping, networks. Most importantly, comparison of each of the brain tumor type-specific networks revealed a network unique to PA that included repressed expression of ONECUT2, a gene frequently methylated in other tumor types, and 13 other uniquely predicted TF-gene interactions. Conclusions These results suggest specific transcriptional pathways that may operate to create the unique molecular phenotype of PA and thus opportunities for corresponding targeted therapeutic

    Malignant astrocytomas, which are highly invasive, vascular neoplasms, compose the majority of nervous system tumors in humans. Elevated expression of fibroblast growth factors (FGFs) in astrocytomas has implicated the FGF family of mitogens in the initiation and progression of astrocyte-derived tumors. In this study, the authors demonstrated that human astrocytomas undergo parallel changes in FGF-receptor (FGFR) expression during their progression from a benign to a malignant phenotype. FGFR type 2 (BEK) expression was abundant in normal white matter and in all low-grade astrocytomas but was not seen in malignant astrocytomas. Conversely, FGFR type 1 (FLG) expression was absent or barely detectable in normal white matter but was significantly elevated in malignant astrocytomas. Malignant astrocytomas also expressed an alternatively spliced form of FGFR-1 (FGFR-1[beta]) containing two immunoglobulin-like disulfide loops, whereas normal human adult and fetal brains expressed a receptor form (FGFR-1[alpha]) containing three immunoglobulin-like disulfide loops. Intermediate grades of astrocytic tumors exhibited a gradual loss of FGFR-2 and a shift in expression from FGFR-1[alpha] to FGFR-2 and a shift in expression from FGFR-1[alpha] to FGFR-1[beta] as they progressed from benign to malignant phenotype. These results suggest that differential expression and alternative splicing of FGFRs may be critical in the malignant progression of astrocytic tumors.

    Disseminated glioneuronal tumors of childhood are rare. We present a retrospective IRB-approved review of the clinical course and frequency of BRAF mutations in disseminated glioneuronal tumors at two institutions. Defining features of our cohort include diffuse leptomeningeal-spread, often with a discrete spinal cord nodule and oligodendroglioma-like histologic features. Patients were identified through a pathology database search of all cases with disseminated low-grade neoplasms with an oligodendroglioma-like component. De-identified clinical information was collected by chart review and all imaging was reviewed. We retrieved the results of targeted genomic analyses for alterations in BRAF. Ten patients (aged 2-14 years) were identified from the Dana-Farber/Boston Children's Hospital and the Royal Children's Hospital, Melbourne pathology databases. Nine patients received chemotherapy. Eight patients are alive, although three have had episodes of progressive disease. We identified genomic alterations affecting the MAPK pathway in six patients. One patient had a germline RAF1 mutation and a clinical diagnosis of cardio-facio-cutaneous syndrome. BRAF duplications were identified in four and BRAF V600E mutation was identified in one. These data support the presence of targetable genomic alterations in this disease.

    Race/ethnic disparities in utilization of children's mental health care have been well documented and are particularly concerning given the long-term risks of untreated mental health problems (Institute of Medicine, 2003; Kessler et al. Am J Psychiatry 152:10026-1032, 1995). Research investigating the higher rates of unmet need among race/ethnic minority youths has focused primarily on policy, fiscal, and individual child or family factors that can influence service access and use. Alternatively, this study examines provider behavior as a potential influence on race/ethnic disparities in mental health care. The goal of the study was to examine whether patient (family) race/ethnicity influences physician diagnostic and treatment decision-making for childhood disruptive behavior problems. The study utilized an internet-based video vignette with corresponding survey of 371 randomly selected physicians from across the USA representing specialties likely to treat these patients (pediatricians, family physicians, general and child psychiatrists). Participants viewed a video vignette in which only race/ethnicity of the mother randomly varied (non-Hispanic White, Hispanic, and African American) and then responded to questions about diagnosis and recommended treatments. Physicians assigned diagnoses such as oppositional defiant disorder (48 %) and attention deficit disorder (63 %) to the child, but there were no differences in diagnosis based on race/ethnicity. The majority of respondents recommended psychosocial treatment (98 %) and/or psychoactive medication treatment (60 %), but there were no significant differences based on race/ethnicity. Thus, in this study using mock patient stimuli and controlling for other factors, such as insurance coverage, we did not find major differences in physician diagnostic or treatment decision-making based on patient race/ethnicity.

    Although optic pathway gliomas are the most common brain tumors associated with neurofibromatosis type 1 (NF1), extra-optic gliomas occur and may behave more aggressively with outcomes that differ by age. A retrospective case-control study was designed to describe the clinical course of adult NF1 patients with progressive extra-optic pilocytic astrocytomas (PAs) and compare to a pediatric cohort. Data for patients treated at the Johns Hopkins Comprehensive Neurofibromatosis Center from 2003 to 2013 were reviewed to identify cases (adults, age >18) and controls (pediatric, age NF1 cases and four pediatric NF1 controls were identified. Mean age was 32.3 ± 9.5 years, 66% male (cases); 12.8 ± 4.2 years, 100% male (controls). Symptomatic progression occurred in two-of-three adults (67%) while the majority of pediatric patients presented with isolated radiographic progression (n = 3, 75%). Onset tended to be more rapid in adults (4 ± 1 vs. 14 ± 8.3 months, P = 0.10). Subtotal resection was the treatment for all pediatric patients. Radiotherapy (n = 2), chemotherapy (n = 2), and targeted, biologic agents (n = 2) were administered in adults. Although all pediatric patients are living, outcomes were universally poor in adults with progression to death in all (median survival 17.1 months, range 6.6-30.3). In conclusion, despite grade I histology, all three adult NF1 patients with progressive extra-optic PAs suffered an aggressive clinical course which was not seen in pediatric patients. Clinicians should be aware of this clinico-histologic discrepancy when counseling and managing adult NF1 patients with progressive extra-optic PAs. © 2016 Wiley Periodicals, Inc.

    Targeting of lysosomes is a novel therapeutic anti-cancer strategy for killing the otherwise apoptosis-resistant cancer cells. Such strategies are urgently needed for treatment of brain tumors, especially the glioblastoma, which is the most frequent and most malignant type. The aim of the present study was to investigate the presence of lysosomes in astrocytic brain tumors focussing also on the therapy resistant tumor stem cells. Expression of the lysosomal marker LAMP-1 (lysosomal-associated membrane protein-1) was investigated by immunohistochemistry in 112 formalin fixed paraffin embedded astrocytomas and compared with tumor grade and overall patient survival. Moreover, double immunofluorescence stainings were performed with LAMP-1 and the astrocytic marker GFAP and the putative stem cell marker CD133 on ten glioblastomas. Most tumors expressed the LAMP-1 protein in the cytoplasm of the tumor cells, while the blood vessels were positive in all tumors. The percentage of LAMP-1 positive tumor cells and staining intensities increased with tumor grade but variations in tumors of the same grade were also found. No association was found between LAMP-1 expression and patient overall survival in the individual tumor grades. LAMP-1/GFAP showed pronounced co-expression and LAMP-1/CD133 was co-expressed as well suggesting that tumor cells including the proposed tumor stem cells contain lysosomes. The results suggest that high amounts of lysosomes are present in glioblastomas and in the proposed tumor stem cells. Targeting of lysosomes may be a promising novel therapeutic strategy against this highly malignant neoplasm.

    Common concern about the biological effects of electromagnetic fields (EMF) is increasing with the expansion of X-band microwaves (MW). The purpose of our work was to determine whether exposure to MW pulses in this range can induce toxic effects on human astrocytoma cells. Cultured astrocytoma cells (Clonetics line 1321N1) were submitted to 9.6 GHz carrier, 90% amplitude modulated by extremely low frequency (ELF)-EMF pulses inside a Gigahertz Transversal Electromagnetic Mode cell (GTEM-cell). Astrocytoma cultures were maintained inside a GTEM-incubator in standard culture conditions at 37+/-0.1 degrees C, 5% CO2, in a humidified atmosphere. Two experimental conditions were applied with field parameters respectively of: PW 100-120 ns; PRF 100-800 Hz; PRI 10-1.25 ms; power 0.34-0.60 mW; electric field strength 1.25-1.64 V/m; magnetic field peak amplitude 41.4-54.6 microOe. SAR was calculated to be 4.0 x 10-4 W/Kg. Astrocytoma samples were grown in a standard incubator. Reaching 70-80% confluence, cells were transferred to a GTEM-incubator. Experimental procedure included exposed human astrocytoma cells to MW for 15, 30, 60 min and 24 h and unexposed sham-control samples. Double blind method was applied. Our results showed that cytoskeleton proteins, cell morphology and viability were not modified. Statistically significant results showed increased cell proliferation rate under 24h MW exposure. Hsp-70 and Bcl-2 antiapoptotic proteins were observed in control and treated samples, while an increased expression of connexin 43 proteins was found in exposed samples. The implication of these results on increased proliferation is the subject of our current research.

  6. LOX expression and functional analysis in astrocytomas and impact of IDH1 mutation.

    Roseli da Silva

    Full Text Available Lysyl oxidase (LOX is involved in vital biological processes such as cell motility, cell signaling and gene regulation. Deregulation of this protein can contribute to tumor formation and progression. Although it is known that LOX is involved in invasion, proliferation and tumor migration in other types of tumors, studies of LOX in astrocytomas of different grades are scarce. The purpose of our study was to characterize LOX, BMP1 and HIF1A expression by real-time PCR in astrocytomas with WHO grades I to IV compared to non-neoplastic brain tissue. IDH1 mutational status was determined by PCR and sequencing. LOX protein expression was also analyzed by immunohistochemistry. LOX functional analyses were performed using siRNA knockdown and the specific inhibitor BAPN in two glioblastoma cell lines. The expression levels of LOX, BMP1 and HIF1A were correlated and analyzed according to IDH1 mutation status and to the clinical end-point of overall survival of glioblastoma patients. The results demonstrate that increased expression and activity of LOX, BMP1 and HIF1A were positively correlated with the malignant grade of astrocytomas. LOX protein expression also increased according to the degree of malignancy, with localization in the cytoplasm and nucleus and staining observed in endothelial cells. Glioblastoma with a mutation in IDH1 expressed lower levels of LOX in the nucleus, and IDH1-mutated cases showed lower LOX expression levels when compared to wild-type IDH1 cases. LOX knockdown and inhibition by BAPN in U87MG and A172 cell lines affected migration, invasion and soft agar colony formation. Taken together, these results corroborate the role of LOX in the migration, invasion and angiogenesis of astrocytomas. Furthermore, LOX expression is influenced by IDH1 mutational status. This work provides new insights for researchers aiming to design targeted therapies to control astrocytomas.

    Background Studies have shown that abnormal activation of the sonic hedgehog pathway is closely related to tumorigenesis in central nervous system.This study aimed to investigate the role of the sonic hedgehog signaling pathway in the occurrence of brainstem and supratentorial glioma.Methods Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) and immunohistochemistry were used to detect the expression of sonic hedgehog-related components in 5 specimens of normal brain tissue,10 of grade Ⅱ brainstem glioma,and 10 of grade Ⅱ supratentorial glioma.The significance of differences between two groups was determined using the Mann-Whitney U test or the two-sample test according to the results of normality distribution tests.Results The mRNA expression levels of sonic hedgehog-related genes were higher in brainstem astrocytomas than in supratentorial astrocytomas and normal brain tissue.The level of protein patched homolog 1 (PTCH1) was significantly higher in brainstem astrocytomas than in supratentorial astrocytomas and normal brain tissue (P <0.01).Immunohistochemistry semi-quantitative analysis was consistent with the qRT-PCR result that PTCH1 expression was increased significantly in brainstem astrocytomas at the protein level (P <0.05).Conclusions Enhanced PTCH1 expression and activation of the sonic hedgehog pathway are involved in brainstem glioma.This may be related to the difference in malignant biological behavior between brainstem and hemispheric glioma,and could be an ideal therapeutic target in brainstem glioma.

    Oral rehydration solution (ORS) and zinc are the recommended treatment in developing countries for the management of uncomplicated diarrhoea in children under five (World Health Organization and UNICEF 2004). However, drug sellers often recommend costly and unnecessary treatments instead. This article reports findings from an experiment to encourage licensed chemical sellers (LCS) in Ghana to recommend ORS and zinc for the management of childhood diarrhoea. The intervention consisted of mobile phone text messages (Short Message Service or SMS) sent to a randomly assigned group of LCS who had been trained on the diarrhoea management protocols recommended by the World Health Organization (WHO). The SMS campaign comprised informational messages and interactive quizzes sent over an 8-week period. The study measured the impact of the SMS messages on both reported and actual practices. Analysis of data from both face-to-face interviews and mystery client visits shows that the SMS intervention improved providers' self-reported practices but not their actual practices. The study also finds that actual practices deviate substantially from reported practices.

    Approximately 1 out of 3 children in the United States is overweight or obese. Family-based treatment (FBT) is considered the gold-standard treatment for childhood obesity, but FBT is both staff and cost intensive. Therefore, we developed the FRESH (Family, Responsibility, Education, Support, & Health) study to evaluate the effectiveness of intervening with parents, without child involvement, to facilitate and improve the child's weight status. Targeting parents directly in the treatment of childhood obesity could be a promising approach that is developmentally appropriate for grade-school age children, highly scalable, and may be more cost effective to administer. The current paper describes the FRESH study which was designed to compare the effectiveness of parent-based therapy for pediatric obesity (PBT) to a parent and child (FBT) program for childhood obesity. We assessed weight, diet, physical activity, and parenting, as well as cost-effectiveness, at baseline, post-treatment, and at 6- and 18-month follow-ups. Currently, all participants have been recruited and completed assessment visits, and the initial stages of data analysis are underway. Ultimately, by evaluating a PBT model, we hope to optimize available child obesity treatments and improve their translation into clinical settings.

    Introduction Bath emollients are widely prescribed for childhood eczema, yet evidence of their benefits over direct application of emollients is lacking. Objectives To determine the clinical and cost-effectiveness of adding bath emollient to the standard management of eczema in children Methods and analysis Design: Pragmatic open 2-armed parallel group randomised controlled trial. Setting: General practitioner (GP) practices in England and Wales. Participants: Children aged over 12 months and less than 12 years with eczema, excluding inactive or very mild eczema (5 or less on Nottingham Eczema Severity Scale). Interventions: Children will be randomised to either bath emollients plus standard eczema care or standard eczema care only. Outcome measures: Primary outcome is long-term eczema severity, measured by the Patient-Oriented Eczema Measure (POEM) repeated weekly for 16 weeks. Secondary outcomes include: number of eczema exacerbations resulting in healthcare consultations over 1 year; eczema severity over 1 year; disease-specific and generic quality of life; medication use and healthcare resource use; cost-effectiveness. Aiming to detect a mean difference between groups of 2.0 (SD 7.0) in weekly POEM scores over 16 weeks (significance 0.05, power 0.9), allowing for 20% loss to follow-up, gives a total sample size of 423 children. We will use repeated measures analysis of covariance, or a mixed model, to analyse weekly POEM scores. We will control for possible confounders, including baseline eczema severity and child's age. Cost-effectiveness analysis will be carried out from a National Health Service (NHS) perspective. Ethics and dissemination This protocol was approved by Newcastle and North Tyneside 1 NRES committee 14/NE/0098. Follow-up will be completed in 2017. Findings will be disseminated to participants and carers, the public, dermatology and primary care journals, guideline developers and decision-makers. Trial registration number ISRCTN

    Childhood obesity has important consequences for health and wellbeing both during childhood and also in later adult life. The rising prevalence of childhood obesity poses a major public health challenge in both developed and developing countries by increasing the burden of chronic non-communicable diseases. Despite the urgent need for effective preventative strategies, there remains disagreement over its definition due to a lack of evidence on the optimal cut-offs linking childhood BMI to dis...

  18. [Orthopedic and surgical treatment of idiopathic scoliosis in childhood and adolescence].

    2006-01-31

    Any evolutive scoliosis must be treated actively. The orthopaedic treatment by brace makes it possible to slow down the spinal deformity evolution. In many cases, physiotherapy could be of great help during the conservative treatment phase. Thus, it is possible to contain the scoliosis progression during the rapid growth phase of the spine, in adolescence. In some patients, spinal deformity can remain moderate, making it possible to keep a satisfying function and balance of the spine in adulthood. Sometimes, the orthopaedic treatment alone is not sufficient and surgery is necessary to provide a well-balanced spine with an acceptable residual spinal deformity. The aims of surgical treatment are to correct spinal deformity by means of vertebral osteosynthesis and to stabilize the final correction by means of bone grafting. These surgical procedures made according to strict rules, give excellent functional results and make it possible to carry out a strictly normal adult life.

    2015-09-01

    Adverse and potentially traumatic experiences (PTEs) in childhood were examined among 54 adult refugee patients with pre-flight PTEs of war and human rights violations (HRVs) and related to mental health and quality of life at treatment start. Extent of childhood PTEs was more strongly related to mental health and quality of life than the extent of war and HRV experiences. Childhood PTEs were significantly related to arousal and avoidance symptoms of posttraumatic stress disorder (PTSD) and to quality of life, whereas pre-flight war and HRV experiences were significantly related to reexperiencing symptoms of PTSD only. Within childhood adversities, experiences of family violence and external violence, but not of loss and illness, were significantly related to increased mental health symptoms and reduced quality of life. These results point to the importance of taking childhood adverse experiences into account in research and treatment planning for adult refugees with war and HRVs trauma.

    Ritter, J; Creutzig, U; Schellong, G

    1992-01-01

    Acute myelogenous leukemia (AML) represents a heterogenous group of leukemias in adults as well as in children. The BFM group initiated 3 consecutive studies on the treatment of this disease. Between December 1978 and April 1991, 543 children under the age of 17 years entered the 3 consecutive multicenter studies, AML-BFM-78 (n = 151), AML-BFM-83 (n = 182), and the still ongoing study AML-BFM-87 (n = 210). The treatment strategy of BFM-78 consisted of an eight week induction/-consolidation regimen employing 7 different drugs together with cranial irradiation, followed by continuous maintenance for two years. The main alteration in the second study BFM-83 was the addition of an intensive 8-day ADE induction course (cytosine arabinoside, daunorubicin, etoposide). In the ongoing trial BFM-87 two courses of HD-ARA-C and etoposide are given after consolidation. CR rates were 80% in trials I and II, and 78% in trial III. The probability of a 4.5-year event-free survival was 35%, SD 4% in study I; 49%, SD 4% in study II, and 45%, SD 4% in study III. The probability of a 4.5-year event-free interval (EFI) was increased from 45%, SD 5% in study I to 61%, SD 4% in study II, it is in the same range in study III (58%, SD 5%). Seven of 10 children which underwent bone marrow transplantation (BMT) in 1. CR are still in first CR after a maximum follow-up time of 3.5 yrs. In summary, the addition of HD-ARA-C together with etoposide given after induction/consolidation treatment did not further reduce the incidence of relapses in childhood AML. So far, the results of study BFM-87 are in the same range than those of study BFM-83.

    Loss-of-function of alpha thalassemia/mental retardation syndrome X-linked (ATRX) protein leads to a phenotype called alternative lengthening of telomeres (ALT) in some tumors. High-grade astrocytomas comprise a heterogeneous group of central nervous system tumors. We examined a large cohort of adult (91) and pediatric (n=88) high-grade astrocytomas as well as lower grade forms (n=35) for immunohistochemical loss of ATRX protein expression and the presence of ALT using telomere-specific fluorescence in situ hybridization, with further correlation to other known genetic alterations. We found that in pediatric high-grade astrocytomas, 29.6% of tumors were positive for ALT and 24.5% were immunonegative for the ATRX protein, these two alterations being highly associated with one another (PATRX protein immunonegative cases (PATRX protein expression in our adult high-grade astrocytomas. In both cohorts, however, the ALT positive high-grade astrocytomas showed more frequent amplification of the platelet-derived growth factor receptor alpha gene (PDGFRA; 45% and 50%, respectively) than the ALT negative counterparts (18% and 26%; P=0.03 for each). In summary, our data show that the ALT and ATRX protein alterations are common in both pediatric and adult high-grade astrocytomas, often with associated PDGFRA gene amplification.

    Autoimmune hemolytic anemia (AIHA) is a rare disease in children, and its clinical severity varies. To better understand disease manifestation and treatment outcome, we analyzed 68 children diagnosed as AIHA for clinical characteristics, laboratory findings, and treatment outcomes. Data show that primary AIHA accounted for 39.7% of all patients, whereas secondary AIHA accounted for 60.3%. Among them, Evans syndrome (ES) accounted for 20 cases (29.4%). Average hemoglobin was lower in the 1-year or below age group than in the above 1-year age group, combined-antibody group than single-antibody group, and IgM-contained group than non-IgM-contained group (Panemia correlates with age and serologic types of direct antiglobulin test. Glucocorticoid is efficacious for AIHA regardless of whether it is a first attack or relapse in this cohort of young patients. ES needs longer treatment duration. IVIG does not improve the outcome of AIHA.

    A retrospective study of children attending a government hospital in Bangalore was performed to assess the causes of delay in providing appropriate treatment. Delay had occurred in 59% of children with significant illness, and in over half the cases the primary cause of delay was inappropriate treatment or delayed referral by a doctor trained in Western-style medicine. It is concluded that there are a large number of ill children in Bangalore whose parents are seeking the help of such doctors but where management is at fault.

    2015-03-26

    In spite of the fact that anaplastic astrocytoma is an uncommon disease, very often the pathology of this disease is associated with lethal effects due to the late diagnosis and unspecific treatments. This paper reports the synthesis and the biological effect on the growth of U373 cell line (human anaplastic astrocytoma) of new hybrid compounds based on 5,16-pregnadiene scaffold linked to an anti-inflammatory drug (6a-e). Moreover, we also determined the cell growth effect of five non-steroidal anti-inflammatory drugs (naproxen, ibuprofen, ketoprofen, indomethacin and sulindac) as well as the free steroidal alcohol 5. The results from this study indicated that sulindac as well as compound 5 decreased the number of U373 cells at different concentrations. However, when an anti-inflammatory drug was bound to the steroidal structure (5), the resulting compounds (6a-e) showed an enhanced biological effect with exception of hybrid 6c. Furthermore, derivative 6e (sulindac hybrid) did not allow cell growth during six days of experiment at a concentration of 10 μM. The overall data indicated that these molecules showed an anti-proliferative activity on anaplastic astrocytoma cell line.

    Thirty-one children under the age of 15 years with verified medulloblastoma were treated at Addenbrookes Hospital from 1940 to 1976. In addition to surgical treatment, all received high dose irradiation to the whole neuraxis. Nine were still alive in 1979, of whom eight were examined. All these patients showed some residual problems, but five were leading active lives and had only minor physical disability. There was evidence of disturbance in growth in all the children. Growth hormone secretion in response to exercise was, however, normal in five of six patients tested. Frank mental retardation was present in three children. A raised resing TSH level was found in two children, one of whom had a multinodular goiter. Long-term follow-up of children who survive medulloblastoma is clearly necessary and consideration should perhaps be given to revision of current treatment regimes in very young children.

    To report the safety and efficacy of combined cyclophosphamide and rituximab treatment in Saudi children with systemic lupus erythematosus (SLE). Medical records of all children with SLE treated with cyclophosphamide and rituximab between June 2007 and June 2012 at King Faisal Specialist Hospital and Research Center, Riyadh, were reviewed for demographic characteristics, age at diagnosis, concomitant treatments, indication of using rituximab and adverse events during the treatment period. Clinical and serologic response parameters included SLE Disease Activity Index (SLEDAI), complement, anti-ds DNA antibody and ANA levels, and mean daily corticosteroid dose assessed 3 months before combined cyclophosphamide and rituximab infusion course and at 6-month interval afterward. Sixteen patients (13 girls) with refractory SLE treated with cyclophosphamide and rituximab were included. The mean age at onset of SLE was 7.8 + 3.3 years, while the mean age at diagnosis was 8.1 + 3.4 years; the mean disease duration was 4.7 + 3.2 years. All patients were treated with corticosteroid and immunosuppressive drugs. Nephritis (8 patients) was the most frequent indication; other indications included refractory arthritis, thrombocytopenia, severe mucocutaneous lesions and central nervous system involvement. All patients received 2 doses, but 4 required 4-8 extra doses. All patients showed improvement in response parameters. There was significant reduction in SLEDAI (P < 0.0002) and corticosteroid dose (P < 0.005). A total of 4 adverse events were notified; 2 developed infusion-related reactions. One patient had severe soft tissue fungal infection, and other patient had pancreatitis. Our data showed beneficial therapeutic and steroid-sparing effects of rituximab as adjunctive treatment for children with refractory SLE including both renal and extrarenal manifestations. Although rituximab was well tolerated by the majority of patients, it may associated with various adverse events.

    Cetirizine (Zyrtec) is a potent and long-acting second-generation histamine H1- receptor antagonist for the treatment of allergic disease, such as allergic rhinitis and chronic idiopathic urticaria, in adult and child. It is a racemic mixture of levocetirizine (Xyzal) and dextrocetirizine. The purpose of this present study was to compare the efficacy of cetirizine, levocetirizine and placebo for the treatment of pediatric perennial allergic rhinitis. 74 perennial allergic rhinitis patients, aged 6 to 12 years old, assigned to 1 of 3 treatment groups for 12 weeks randomly. The effects of the three agents were compared with the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) and Total Symptom Score (TSS) by diary. Nasal peak expiratory flow rate (nPEFR) and laboratory examinations including serum immunoglobulin E level, eosinophil cationic protein (ECP), blood eosinophil counts and eosinophil percentage in a nasal smear were evaluated among the three groups. The results revealed that both cetirizine and levocetirizine improved TSS in comparison with the placebo group, and ceterizine appeared to be more efficacious than levocetirizine at week 8 and week 12. The PRQLQ score showed significant decreased both in cetirizine and levocetirizine group, but there was no statistic significant difference between both groups. The eosinophil proportion in a nasal smear significantly decreased among the cetirizine in comparison with the placebo group but there was no statistic significant in levocetirizine groups. Both cetirizine and levocetirizine showed significant improvement in nPEFR in comparison with the placebo group, and ceterizine appeared to be more efficacious than levocetirizine. The 12-week treatment program showed that cetirizine was more effectious than levocetirizine.

    Full Text Available ABSTRACT This paper reports a case of a rare variant of the cervical spinal cord astrocytoma diagnosed in a dog with progressive neurological signs, initially asymmetrical, not ambulatory tetraparesis, segmental reflexes and normal muscle tone in all four limbs and absence of pain upon palpation of the cervical spine. Myelography revealed attenuation of the ventral and dorsal contrast line in the third region of the fifth cervical vertebra. At necropsy intramedullary cylindrical mass that stretched from the third to the sixth cervical vertebra, which replaced all the gray matter of the spinal cord was observed. In the histological study, there was the replacement of the substance by neoplastic cells mantle arranged loosely. The cells were large and slightly rounded. The eosinophilic cytoplasm was well defined, sometimes forming processes interconnecting cells. The nucleus was eccentric, round, oval or kidney-shaped, and the nucleolus was evident. Thus, the microscopic changes observed in the cervical spinal cord were consistent with gemistocytic astrocytoma.

    Pilocytic astrocytoma with leptomeningeal dissemination is a rare phenomenon and can be associated with obstructive hydrocephalus and an unfavorable prognosis. Herein, we report a seventeen-year-old boy with a history of ventriculo-peritoneal shunt insertion due to severe hydrocephalus who presented with progressive headache and vomiting together with ocular and cerebellar signs and symptoms. Neuroimaging confirmed the presence of multiple intracranial masses in the cerebellum and thalamus. Intracranial dissemination of tumor to the the leptomeninges was seen during neuroendoscopy. Simultaneous biopsy and endoscopic third ventriculostomy were performed and the diagnosis of low-grade pilocytic astrocytoma with leptomeningeal dissemination was made by histological examination. The patient underwent chemotherapy in combination with radiotherapy to reduce the risk of reoccurrence of the primary tumor and was followed for one year.

    Segmental omental infarction (SOI) is an uncommon cause of right lower quadrant pain in children that is often misdiagnosed as appendicitis. During the last decade, imaging findings of SOI have proved to be sufficiently typical to avoid unnecessary surgery in the majority of reported adult patients. The condition has a spontaneous favourable evolution under medical treatment. In children the surgical option remains controversial. We report a typical case of SOI in a 10-year-old boy. The diagnosis was suspected by sonography, unambiguously confirmed by multidetector CT and successfully treated conservatively. This report emphasizes the use of CT in selected acute abdominal situations, peculiarly in obese children, to avoid unnecessary surgery. (orig.)

    Full Text Available Background: Health-related quality of life (HRQoL in cancer has been related to several protective and risk factors such as perceived social support (PSS and coping. However, their effects on HRQoL once patients are in survivorship have not been fully described in pediatric samples. Objective: To describe and explore the relationship between HRQoL in survivorship and some factors (PSS, coping present while active treatment. Methods: Cross-sectional study. Forty-one pediatric cancer survivors answered HRQoL measures referred to survivorship, as well as PSS and coping measures referred to treatment period. Results: The discriminant function obtained succeeds to correctly classify 78% of the sample. Survivors who showed high HRQoL were those who, in the hardest moment while hospitalization, perceived satisfactory emotional support (from nurses and did not deploy a wide range of active coping resources to cope with stressful events (only social action coping strategy showed a significant relationship with HRQoL. Conclusions and implications: Considering these outcomes, educational and counseling interventions to strengthen patients' social networks and supportive relationships are recommended, specially, among health providers (nurses. These results highlight the importance of not overlooking opportunities to address the emotional needs of patients while hospitalization, since a positive and endurable effect has been observed at survivorship.

    Pilocytic astrocytoma and ganglioglioma may occur in inaccessible or surgically difficult areas. In case of incomplete resection, the availability of biological predictors of tumour progression could be particularly important. To this end, an analysis of p53 codon 72 polymorphism and assessment of its role as prognostic marker were performed. The status of the p53 Arg72Pro polymorphism was evaluated by pyrosequencing method in a multicenter cohort of 170 paediatric patients. Genotype/phenotype associations were investigated either by means of bivariate or multivariate analyses. In the partially resected pilocytic astrocytomas, the Arg/Arg variant predicts early tumour progression (median survival time: 23.1 months) and is associated with poor event-free survival (p value = 0.0009). This finding remains true also in case of adjuvant therapies, with a 5-year event-free survival of 30.6% for cases with Arg/Arg variant vs. 78.7% for those with other genotypes. There is no association between ganglioglioma and the polymorphism. The assessment of Arg/Arg variant could improve the management of pilocytic astrocytoma. TP53 codon 72 analysis could distinguish low-risk cases, in which surgery could be conservative, from high-risk cases needing an aggressive surgery plan. PMID:27374106

    Low-grade brain tumors (pilocytic astrocytomas) arising in the neurofibromatosis type 1 (NF1) inherited cancer predisposition syndrome are hypothesized to result from a combination of germline and acquired somatic NF1 tumor suppressor gene mutations. However, genetically engineered mice (GEM) in which mono-allelic germline Nf1 gene loss is coupled with bi-allelic somatic (glial progenitor cell) Nf1 gene inactivation develop brain tumors that do not fully recapitulate the neuropathological features of the human condition. These observations raise the intriguing possibility that, while loss of neurofibromin function is necessary for NF1-associated low-grade astrocytoma development, additional genetic changes may be required for full penetrance of the human brain tumor phenotype. To identify these potential cooperating genetic mutations, we performed whole-genome sequencing (WGS) analysis of three NF1-associated pilocytic astrocytoma (PA) tumors. We found that the mechanism of somatic NF1 loss was different in each tumor (frameshift mutation, loss of heterozygosity, and methylation). In addition, tumor purity analysis revealed that these tumors had a high proportion of stromal cells, such that only 50%-60% of cells in the tumor mass exhibited somatic NF1 loss. Importantly, we identified no additional recurrent pathogenic somatic mutations, supporting a model in which neuroglial progenitor cell NF1 loss is likely sufficient for PA formation in cooperation with a proper stromal environment.

    Monitoring the long-term radiotherapy-associated molecular changes in low-grade gliomas (LGGs)facilitates the understanding of LGG response to radiotherapy. In this study, we used immunohistochemistry to analyze the expression of Ki-67,tumor protein P53 (TP53),P21,and P27 in 8paired WHO grade Ⅱ astrocytoma samples.The interval between radiotherapy (RT) and the second surgery was more than 3 months in all cases.The average Ki-67 labeling index (LI) was 5.3% in pre-RT samples and 11.54% in post-RT samples.Ki-67 LI was higher in the primary tumors that underwent malignant transformation observed at the second surgery after radiation.Post-RT Ki-67 LI decreased in 2 cases with an interval of less than 12 months between RT and the second surgery.TP53 expression was found in 3 out of 4 pre-RT samples with malignant transformation and in 1 out of 4 pre-RT samples without malignant transformation.Post-RT TP53 increased in 2 cases in which increased expression of P21 or P27 was also observed.Our study suggests that radiotherapy can inhibit WHO grade Ⅱ astrocytoma proliferation as reflected by Ki-67 LI,but the effect attenuates with time.In addition,there is a tendency of malignant transformation for WHO grade Ⅱ astrocytomas with a high Ki-67 level or TP53 expression in initial samples.

    The current study examined whether parental and contextual risk factors contribute to mothers' and fathers' differential treatment (MDT/FDT) when accounting for sibling dyad characteristics. Also explored was whether family type (single mothers vs. 2 parents) moderated the links between the parental and contextual correlates and MDT. One hundred and seventy-two families with older (M= 7.4 years) and younger (M= 5.2 years) siblings were studied. Parents and children reported about the parent-child relationship, and parents reported about the children's characteristics, their own psychological resources, and contextual factors. Controlling for sibling dyad characteristics, FDT was predicted most consistently by household chaos. Furthermore, single mothers were not at risk per se for using more MDT but only when coupled with high maternal anger.

    Diabetes, which is diagnosed before 6 months of age, is patogenetically different than type 1 diabetes. This kind of diabetes also known as a neonatal diabetes is genetically determined with monogenic mode of inheritance. Most of these patients are carriers of heterozygous mutation in the KCNJ11 or ABCC8 gene. These mutations may activate the Kir6.2/SUR1 potassium channel in the beta cells and disturb insulin secretion, which in consequence leads to diabetes. This patological phenomenon is reversible if sulfonylureas are used as a first line therapy. In the current paper a systematic review of clinical aspects of sulfonylurea treatment in neonatal diabetes has been performed. This gives the further evidence that knowlegde of the patogenesis of neonatal diabetes may be easily transferred to bedside and clinical practice.

    Full Text Available Atopic dermatitis (AD is a chronic inflammatory skin disorder caused by a dysregulation of immune response to allergenic or non-allergenic stimuli. Interplay of several effector cells including migrating lymphocytes, fibrocytes, Langerhans cells, mast cells and epidermal keratinocytes enroll in the development of AD. Atopic dermatitis affects approximately 20% of children and persists in 6% of adults. Relieving acute exacerbations, improving the quality of life and prevention of side effects in the long term are the main steps of the management of AD. Mild to moderate cases can be controlled with avoidance of triggering factors, skin care and topical medications. In severe cases immune suppression is an option with cumulative toxicity and variable efficacy of drugs as a limiting factor. It is essential to develop safer and efficacious alternatives for the treatment of AD, especially in pediatric age group. (Journal of Current Pediatrics 2011; 9: 39-43

    Diarrhea is the fourth leading cause of child mortality in Ghana. In 2010, Ghana endorsed guidelines from the World Health Organization and the United Nations Children's Fund for use of zinc with low-osmolarity oral rehydration salts (ORS) for the treatment of acute childhood diarrhea. From late 2011 through 2014, the Strengthening Health Outcomes through the Private Sector (SHOPS) project implemented a comprehensive program in 3 regions of Ghana to increase the availability and use of ORS and zinc and to decrease incorrect use of antibiotics and antidiarrheals. The program included (1) partnering with local pharmaceutical firms to introduce and market locally produced zinc products, (2) collaborating with the Ghanaian Pharmacy Council to provide training and supportive supervision of private-sector providers on diarrhea management, and (3) conducting mass media campaigns to raise caregiver awareness. We evaluated the effect of this program using a baseline survey of 754 caregivers of children under 5 with diarrhea at the start of the intervention in 2012 and a follow-up survey of 751 caregivers in 2014. Regression analysis showed that use of ORS with zinc increased from 0.8% in 2012 to 29.2% in 2014 (P<.001), and antibiotic use declined from 66.2% to 38.2% (P<.001) during the same period. The magnitude and statistical significance of these results remained the same after including potential confounding factors as covariates. Inappropriate antibiotic use, however, remained high at follow-up. We conclude that similar programs applied in other settings have the potential to rapidly scale up use of ORS and zinc. Additional efforts are required to reduce persistent incorrect antibiotic use.

    Full Text Available OBJECTIVES: Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control; therefore, the aim of the study was to determine whether a digital media tool, which features portability on mobile phones, modifies the assimilation of the inhalation technique. METHODS: A total of 66 professionals working in the health care area with the pediatric population were selected. They were submitted to a pre-test on their knowledge of inhalation therapy. The professionals were randomized into two groups (A and B. Group A received a media application on their mobile phones showing the steps of inhalation therapy, while group B received the same information in written form only. A post-test was applied after 15 days. The results (pre- and post- were analyzed by two pediatric pulmonologists. RESULTS: Of the 66 professionals, 87.9% were females. Of a total possible score of ten, the mean score obtained in the pre-test was 5.3 ± 3, and in the second test, 7.5 ± 2 (p < 0.000. There were no significant differences when comparing the two groups (p = 0.726. The nurses had the lowest mean scores in the initial test (2.3 ± 2; however, they were the group that learned the most with the intervention, showing similar means to those of other groups in the second test (6.1 ± 3. CONCLUSION: There was significant improvement in knowledge about inhalation therapy in all professional categories using both methods, demonstrating that education, when available to professionals, positively modifies medical practice.

It has been reported to be effective in maintaining remission in 70-100 percent of patients with SDNS but somewhat SRNS 0-100 percent. The aim of this study was to evaluate the efficacy of long-term (CsA in children with refractory nephrotic syndrome (RNS and steroid dependent nephrotic syndrome (SDNS. Materials and Methods: The long-term effect of (CsA in 91 Iranian children aged 3 months to 11 years (54 with RNS and 37 with SDNS was assessed between 1984 and 1999. Eighty of 91 children received renal biopsy prior to introduction of (CsA, and the other 11 patients had not consent for kidney biopsy. If the patients did not show remission aftre receiving 3-6 months of (CsA, the medication was discontinued. Results: All patient were treated with (CsA in combination with low dose alternate day prednisolone. In children with RNS and SDNS, therapy with (CsA induced, remission in 25 of 54 (46.2 percent and 27 of 37 (73 percent respectively (P<0.02. Of the 32 patients with minimal change disease (MCD, 23 (72 percent responded to therapy, compared with 4 of 18 (22 percent with focal segmental glomerulosclerosis (FSGS (P<0.005.

    Purpose: We evaluated clinical outcomes in the subset of patients who underwent radiotherapy (RT) due to progressive pilocytic astrocytoma within the Multicenter Treatment Study for Children and Adolescents with a Low Grade Glioma HIT-LGG 1996. Patients and methods: Eligibility criteria were fulfilled by 117 patients. Most tumors (65 %) were located in the supratentorial midline, followed by the posterior fossa (26.5 %) and the cerebral hemispheres (8.5 %). Median age at the start of RT was 9.2 years (range 0.7-17.4 years). In 75 cases, external fractionated radiotherapy (EFRT) was administered either as first-line nonsurgical treatment (n = 58) or after progression following primary chemotherapy (n = 17). The median normalized total dose was 54 Gy. Stereotactic brachytherapy (SBT) was used in 42 selected cases. Results: During a median follow-up period of 8.4 years, 4 patients (3.4 %) died and 33 (27.4 %) experienced disease progression. The 10-year overall (OS) and progression-free survival (PFS) rates were 97 and 70 %, respectively. No impact of the RT technique applied (EFRT versus SBT) on progression was observed. The 5-year PFS was 76 {+-} 5 % after EFRT and 65 {+-} 8 % after SBT. Disease progression after EFRT was not influenced by gender, neurofibromatosis type 1 (NF1) status, tumor location (hemispheres versus supratentorial midline versus posterior fossa), age or prior chemotherapy. Normalized total EFRT doses of more than 50.4 Gy did not improve PFS rates. Conclusion: EFRT plays an integral role in the treatment of pediatric pilocytic astrocytoma and is characterized by excellent tumor control. A reduction of the normalized total dose from 54 to 50.4 Gy appears to be feasible without jeopardizing tumor control. SBT is an effective treatment alternative. (orig.)

    Full Text Available Low-grade gliomas arising in dorsal midbrain in children and young patients usually present few neurological symptoms and findings, and patients´ management is controversial. Some authors propose only clinical observation until the patient present signs of increased intracranial pressure when a shunt with or without biopsy, is inserted; others recommend radiotherapy after stereotactic or open biopsy. Microsurgical total removal of tumor may be curative. We present a retrospective analysis of eight patients (mean age 16.6 ±11.5 years-old with low-grade astrocytoma of the tectal region operated on using an infratentorial/ supracerebellar approach between 1981 and 2002. All patients presented hydrocephalus and had a shunt insertion before surgical resection of the lesion. The tumour could be totally resected in seven patients. In one case radical removal was not possible due to infiltrative pattern of the lesion. Postoperative radiotherapy was performed in two cases, one patient at the beginning of this series and in the case with infiltrative tumor. This patient presented progressive tumor growth and died five years after surgery. No recurrence occurred after total removal. Post-surgical follow-up time ranged from 2 1/2 to 22 1/2 years (mean 9.9 ± 5.9 years. Radical microsurgical removal of non invasive tumors is possible without mortality or significant morbidity. It may be curative and should remain as an alternative to be discussed with the patient.Gliomas de baixo grau originários da porção dorsal do mesencéfalo ocorrem em crianças e adultos jovens. Geralmente apresentam pouca sintomatologia e tardia, com hipertensão intracraniana por hidrocefalia não-comunicante. O seu tratamento é controverso.

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

We used a cross-sectional study to evaluate the effect of this shortened training on appropriate IMCI classification and treatment of under-five childhood illness management in Rwanda. Methods: A cross-sectional study was conducted in 22 health centers in Rwanda, comparing data from 121 nurses, where 55 nurses completed the 11-day and 66 nurses completed the 6-day training. Among 768 children, we evaluated clinical outcomes from May 2011 to April 2012. Descriptive statistics were used to display the sociodemographic characteristics of health providers; including level of education, sex, age, and professional experiences. Bivariable and multivariable analyses were used to test for differences between nurses in the 6-day versus 11-day training on the appropriate classification and treatment of childhood illness. Results: Our findings show that at the bivariable level and after controlling for confounders in the multivariable analysis, the only significant differences detected between nurses in the long and short training was the classification of fever (adjusted odds

    Inhibitor of growth 4 (ING-4) is a tumor suppressor gene that interacts with nuclear factor-kappaB (NF-kappaB) and represses its transcriptional activity. Several lines of evidence suggest that the tumor suppressor gene ING-4, the transcription factor NF-kappaB and its target genes matrix metalloproteases MMP-2, MMP-9 and urokinase plasminogen activator (u-PA) are critically involved in tumor invasion. The aim of the present study was to investigate immunohistochemically the expression pattern of ING-4, NF-kappaB and the NF-kappaB downstream targets MMP-2, MMP-9 and u-PA in human astrocytomas from 101 patients. We found that ING-4 expression was significantly decreased in astrocytomas, and ING-4 loss was associated with tumor grade progression. Expression of p65, a NF-kappaB subunit, was significantly higher in grade IV than in grade III and grade I/II tumors, and a statistical significant negative correlation between expression of ING-4 and expression of nuclear p65 was noticed. MMP-9, MMP-2 and u-PA were overexpressed in human astrocytomas. Of note, astrocytomas of advanced histologic grades (grade III, IV) displayed significantly higher expression levels of these proteins compared to tumors of lower grades (grade I, II). Collectively, our data suggest an essential role for ING-4 in human astrocytoma development and progression possibly through regulation of the NF-kappaB-dependent expression of genes involved in tumor invasion.

    The present manuscript is an overview of various effects of mTOR up-regulation in astrocytoma with an emphasis on its deleterious effects on the proliferation of Glioblastoma Multiforme. The manuscript reports consistent evidence indicating the occurrence of mTOR up-regulation both in experimental and human astrocytoma. The grading of human astrocytoma is discussed in relationship with mTOR up-regulation. In the second part of the manuscript, the biochemical pathways under the influence of mTOR are translated to cell phenotypes which are generated by mTOR up-regulation and reverted by its inhibition. A special section is dedicated to the prominent role of autophagy in mediating the effects of mTOR in glioblastoma. In detail, autophagy inhibition produced by mTOR up-regulation determines the fate of cancer stem cells. On the other hand, biochemical findings disclose the remarkable effects of autophagy activators as powerful inducers of cell differentiation with a strong prevalence towards neuronal phenotypes. Thus, mTOR modulation acts on the neurobiology of glioblastoma just like it operates in vivo at the level of brain stem cell niches by altering autophagy-dependent cell differentiation. In the light of such a critical role of autophagy we analyzed the ubiquitin proteasome system. The merging between autophagy and proteasome generates a novel organelle, named autophagoproteasome which is strongly induced by mTOR inhibitors in glioblastoma cells. Remarkably, when mTOR is maximally inhibited the proteasome component selectively moves within autophagy vacuoles, thus making the proteasome activity dependent on the entry within autophagy compartment.

  12. Evidence of Ambiguous Differentiation and mTOR Pathway Dysregulation in Subependymal Giant Cell Astrocytoma

    2012-05-01

    Full Text Available Objective: The exact cell of origin of subependymal giant cell astrocytoma is debated but most currently consider the tumor in the astrocytic category. Mutations and subsequent biallelic inactivation of TSC1 encoding hamartin, or TSC2 encoding tuberin appear to be the underlying genetic aberrations. Inactivation leads to loss of proteins that inhibit mammalian target of rapamycin (mTOR disrupting tightly regulated cell functions.Material and Method: We analyzed the expression of tuberin and hamartin along with an array of neuroepithelial markers in 9 subependymal giant cell astrocytomas. In addition, RPS6 and 4EBP1 regulatory proteins that are downstream in the mTOR pathway were also evaluated.Results: While hamartin and tuberin expression levels were relatively decreased compared to control tissue, this was not of particular practical use to detect the mutated gene since low levels of positivity could be detected throughout the central nervous system. As expected, the levels of RPS6 and 4EBP1 were increased, further confirming the activation of the mTOR pathway. GFAP was positive in 5 cases, while Synaptophysin positivity was found in all tumors. CD34 (a marker often observed in well differentiated glio-neuronal tumors, Olig2 (a nuclear marker present in most gliomas, IDH1 and IDH2 were entirely negative in all tumor cells. Ki67 (MIB-1 showed a low proliferation rate ranging from 2% to 8%.Conclusion: Staining with neuroepithelial markers supports the suggestion of ambiguous differentiation. Subependymal giant cell astrocytomas do not appear to have the typical expression profiles of astrocytic tumors, under which they have been classified.

    Purpose: To assess outcomes of carbon ion radiotherapy for diffuse astrocytomas in adults. Methods and Materials: Between October 1994 and February 2002, 14 patients with diffuse astrocytoma, identified as eligible for carbon ion radiotherapy, were enrolled in a phase I/II clinical trial. Carbon ion radiotherapy was administered in 24 fractions over 6 weeks. The normal tissue morbidity was monitored carefully, and the carbon ion dose was escalated from 50.4 Gy equivalent (GyE) to 55.2 GyE. Patients were divided into two groups according to their carbon ion doses: a low-dose group in which 2 patients were irradiated with 46.2 GyE and 7 patients were irradiated with 50.4 GyE, and a high-dose group in which 5 patients were irradiated with 55.2 GyE. Results: Toxicities were within acceptable limits, and none of the patients developed Grade 3 or higher acute or late reactions. The median progression-free survival (PFS) time was 18 months for the low-dose group and 91 months for the high-dose group (p = 0.0030). The median overall survival (OS) time was 28 months for the low-dose group and not reached for the high-dose group (p = 0.0208). Conclusion: High-dose group patients showed significant improvement in PFS and OS rates compared to those in the low-dose group, and both dose groups showed acceptable toxicity.

    Background: Childhood cancer survivors experience adverse drug events leading to lifelong health issues. The Applying Biomarkers to Minimize Long-Term Effects of Childhood/Adolescent Cancer Treatment (ABLE) team was established to validate and apply biomarkers of cancer treatment effects, with a goal of identifying children at high risk of developing cancer treatment complications associated with thrombosis, graft-versus-host disease, hearing loss, and kidney damage. Cisplatin is a chemotherapy well known to cause acute and chronic nephrotoxicity. Data on biomarkers of acute kidney injury (AKI) and late renal outcomes in children treated with cisplatin are limited. Objective: To describe the design and methods of the pan-Canadian ABLE Nephrotoxicity study, which aims to evaluate urine biomarkers (neutrophil gelatinase–associated lipocalin [NGAL] and kidney injury molecule-1 [KIM-1]) for AKI diagnosis, and determine whether they predict risk of long-term renal outcomes (chronic kidney disease [CKD], hypertension). Design: This is a 3-year observational prospective cohort study. Setting: The study includes 12 Canadian pediatric oncology centers. Patients: The target recruitment goal is 150 patients aged less than 18 years receiving cisplatin. Exclusion criteria: Patients with an estimated glomerular filtration rate (eGFR) renal transplantation at baseline. Measurements: Serum creatinine (SCr), urine NGAL, and KIM-1 are measured during cisplatin infusion episodes (pre-infusion, immediate post-infusion, discharge sampling). At follow-up visits, eGFR, microalbuminuria, and blood pressure are measured and outcomes are collected. Methods: Outcomes: AKI is defined as per SCr criteria of the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines. CKD is defined as eGFR cancer treatment complications. The Nephrotoxicity study is a novel study of AKI biomarkers in children treated with cisplatin that will greatly inform on late cisplatin renal outcomes and follow

    2013-09-01

    Myelodysplastic syndrome (MDS) comprises of a heterogeneous group of bone marrow disorders resulting from a clonal stem cell defect characterised by cytopenias despite a relatively hypercellular marrow, ineffective hematopoiesis, morphological dysplasia in the marrow elements, no response to hematinics such as iron, B12 or folic acid and risk of progression to leukemia. Myelodysplastic syndrome in childhood is extremely rare and accounts for less than 5% of all hematopoietic neoplasms in children below the age of 14 y. The primary MDS in children, also known as de novo MDS differs from secondary MDS which generally follows congenital or acquired bone marrow (BM) failure syndromes as well as from therapy related MDS, commonly resulting from cytotoxic therapy. MDS associated with Down syndrome which accounts for approximately one-fourth of cases of childhood MDS is now considered a unique biologic entity synonymous with Down syndrome-related myeloid leukemia and is biologically distinct from other cases of childhood MDS. Refractory cytopenia of childhood (RCC) is the commonest type of MDS. Genetic changes predisposing to MDS in childhood remain largely obscure. Monosomy 7 is by-far the commonest cytogenetic abnormality associated with childhood MDS; however most cases of RCC show a normal karyotype. Complex cytogenetic abnormalities and trisomy 8 and trisomy 21 are also occasionally observed. The most effective and curative treatment is Hematopoietic stem cell transplantation and this is particularly effective in children with the monosomy 7 genetic defect as well as those displaying complex karyotype abnormalities provided it is instituted early in the course of the disease.

    1984-06-01

    Sixty-eight long-term survivors of childhood cancer were evaluated for dental and maxillofacial abnormalities. Forty-five patients had received maxillofacial radiation for lymphoma, leukemia, rhabdomyosarcoma, and miscellaneous tumors. Forty-three of the 45 patients and the remaining 23 who had not received maxillofacial radiation also received chemotherapy. Dental and maxillofacial abnormalities were detected in 37 of the 45 (82%) radiated patients. Dental abnormalities comprised foreshortening and blunting of roots, incomplete calcification, premature closure of apices, delayed or arrested tooth development, and caries. Maxillofacial abnormalities comprised trismus, abnormal occlusal relationships, and facial deformities. The abnormalities were more severe in those patients who received radiation at an earlier age and at higher dosages. Possible chemotherapeutic effects in five of 23 patients who received treatment for tumors located outside the head and neck region comprised acquired amelogenesis imperfecta, microdontia of bicuspid teeth, and a tendency toward thinning of roots with an enlarged pulp chamber. Dental and maxillofacial abnormalities should be recognized as a major consequence of maxillofacial radiation in long-term survivors of childhood cancer, and attempts to minimize or eliminate such sequelae should involve an effective interaction between radiation therapists, and medical and dental oncologists.

Taking this into consideration, the present study was based on the following question: what practical contributions to clinicians and researchers does the current literature on childhood depression have to offer? The objective of the present study was to conduct a systematic review of articles regarding childhood depression. To accomplish this purpose, a systematic review of articles on childhood depression, published from January 1, 2010 to November 24, 2012, on MEDLINE and SciELO databases was carried out. Search terms were “depression” (medical subject headings [MeSH], “child” (MeSH, and "childhood depression" (keyword. Of the 180 retrieved studies, 25 met the eligibility criteria. Retrieved studies covered a wide range of aspects regarding childhood depression, such as diagnosis, treatment, prevention and prognosis. Recent scientific literature regarding childhood depression converge to, directly or indirectly, highlight the negative impacts of depressive disorders to the children's quality of life. Unfortunately, the retrieved studies show that childhood depression commonly grows in a background of vulnerability and poverty, where individual and familiar needs

    Current astrocytoma models are limited in their ability to define the roles of oncogenic mutations in specific brain cell types during disease pathogenesis and their utility for preclinical drug development. In order to design a better model system for these applications, phenotypically wild-type cortical astrocytes and neural stem cells (NSC) from conditional, genetically engineered mice (GEM) that harbor various combinations of floxed oncogenic alleles were harvested and grown in culture. Genetic recombination was induced in vitro using adenoviral Cre-mediated recombination, resulting in expression of mutated oncogenes and deletion of tumor suppressor genes. The phenotypic consequences of these mutations were defined by measuring proliferation, transformation, and drug response in vitro. Orthotopic allograft models, whereby transformed cells are stereotactically injected into the brains of immune-competent, syngeneic littermates, were developed to define the role of oncogenic mutations and cell type on tumorigenesis in vivo. Unlike most established human glioblastoma cell line xenografts, injection of transformed GEM-derived cortical astrocytes into the brains of immune-competent littermates produced astrocytomas, including the most aggressive subtype, glioblastoma, that recapitulated the histopathological hallmarks of human astrocytomas, including diffuse invasion of normal brain parenchyma. Bioluminescence imaging of orthotopic allografts from transformed astrocytes engineered to express luciferase was utilized to monitor in vivo tumor growth over time. Thus, astrocytoma models using astrocytes and NSC harvested from GEM with conditional oncogenic alleles provide an integrated system to study the genetics and cell biology of astrocytoma pathogenesis in vitro and in vivo and may be useful in preclinical drug development for these devastating diseases.

    Despite progress toward assuring the health of today's young population, the 21(st) century began with an epidemic of childhood obesity. There is general agreement that the situation must be addressed by means of primary prevention, but relatively little is known about how to intervene effectively....... The evidence behind the assumption that childhood obesity can be prevented was discussed critically in this roundtable symposium. Overall, there was general agreement that action is needed and that the worldwide epidemic itself is sufficient evidence for action. As the poet, writer, and scholar Wittner Bynner...... (1881-1968) wrote, "The biggest problem in the world could have been solved when it was small"....

    The treatment of refractory schizophrenia has been a clinical challenge for most psychiatrists; the possible reasons include diagnostic errors,medical conditions and brain dysgenesis.Here,we described a patient with childhood-onset schizophrenia who had severe psychiatric symptoms such as auditory hallucinations and persecutory delusions,and etc.We reexamined all his possible medical conditions and found that the patient had an abnormally enlarged cavus septum pellucidum (CSP) combined with cavum vergae (CV) (maximum length >30 mm).Some reports suggested that abnormal CSP (length >6 mm) has a significant association with schizophrenia.However,abnormally large CSP or CSP/CV and related prognosis were reported rarely.This case suggested that abnormally enlarged CSP or CSP/CV may worsen the prognosis.

    “卫生学假说”可能是导致近年来儿童哮喘发病率增加的原因,大量的临床试验表明在消化系统疾病方面起着积极作用的益生菌制剂能够预防和治疗儿童特应性皮炎、食物过敏,但对预防、治疗哮喘的结论不一,越来越多的动物实验显示了益生菌在哮喘的预防或治疗方面的积极作用,其机制仍在探索中,以乳酸杆菌为代表的益生菌制剂在未来可能为儿童哮喘的临床防治提供新的思路.%“Hygiene hypothesis” may be the reason for the increased incidence of childhood asthma in recent years.A large number of clinical studies indicate that,probiotics,which play a positive role in the digestive system diseases,can prevent and treat children atopic dermatitis as well as food allergies,but the conclusions of prevention and treatment of asthma have been inconsistent.More and more of the animal experiments show that probiotics have benefical effects in the prevention or therapy of asthma,its mechanism is still in the exploration,probiotics such as lactobacillus will provide a new clinical thought for the prevention and treatment of childhood asthma in the future.

    1999-01-01

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.

  15. Guidelines for maintenance treatment of childhood asthma: development of a score card system by multivariate cluster analysis.

    Donnelly, W J; Donnelly, J E; Thong, Y H

    1987-01-01

    Multivariate cluster analysis of data on 128 asthmatic children resulted in the identification of 8 major discriminating variables. Stepwise divisions by this computer programme resulted in the formation of 6 grades of severity. There was significant correlation between higher grades of severity and early onset of the disease (P less than 0.02). There was also significant correlation between higher grades of severity and greater use of interval medications (P less than 0.002). However, 27.3% were receiving inadequate interval medications in respect of their grade of severity. Assignation of a 5-point scale to each of the 8 major discriminating variables resulted in the generation of computer-designated scores commensurate with each grade of severity. This was coupled to current recommendations for stepwise maintenance medications appropriate for each grade. This Score Card system for maintenance management of childhood asthma may prove useful in busy clinical settings.

    2016-01-01

    Full Text Available Incidence of gliomas presenting with hemorrhage is around 3.7–7.2%. Low-grade gliomas account for <1% tumor with hemorrhage. Infants presenting with cerebellar pilocytic astrocytomas (PAs and hemorrhage with thrombocytopenia have not been reported. We report an interesting case of a 9-month-old infant who presented to the emergency department in a drowsy state with recurrent vomiting. Laboratory investigations showed anemia, thrombocytopenia, and coagulopathy. Radiological evaluation showed a large PA with bleed. The patient was treated with retromastoid suboccipital craniotomy and tumor excision and improved postoperatively. Cerebellar PA with bleed and coagulopathy in infants has not been reported in literature till date. Their presentation seems to be acute in nature, and high index of suspicion is required for the diagnosis of these posterior fossa tumors, which can deteriorate rapidly in infants.

    2011-01-01

    Full Text Available Conduction aphasia is a language disorder characterized by an impaired ability to repeat verbal material associated with phonological paraphasias but a relatively fluent spontaneous speech and preserved comprehension. It has been attributed to lesions of the arcuate fasciculus by disconnection between posterior temporal lobe and frontal lobe, however, this idea has been debated, because the integrity and function of the arcuate fasciculus does not seem to be essential in verbal repetition. We report a case of a 23 year old male, with conduction aphasia as a result of a recurrent anaplastic astrocytoma in parietal and temporo-occipital areas. We propose a reconceptualization of the aphasia, analyzing it in terms of clinical neuropsychological and neural networks between ipsilateral and contralateral posterior brain areas

    2016-01-01

    Pilocytic astrocytoma (PA) is one of the most common brain cancers among children and activation of the Mitogen-Activated Protein Kinase (MAPK) pathway is considered the hallmark. In the majority of cases, oncogenic BRAF fusions or BRAF V600E mutations are observed, while RAF1 or NF1 alterations...... are more rarely found. However, in some cases, no apparent cancer driver events can be identified. Here, we describe a novel fusion between the transcription factor nuclear factor 1A (NFIA) and Raf-1 proto-oncogene (RAF1) in a 5-year old boy with PA. The novel fusion was identified as part...... of a comprehensive genomic tumor profiling. We show that the NFIA:RAF1 fusion results in constitutive Raf1 kinase activity, leading to activation of downstream MEK1/2 cascade and increased proliferation of cancer cells. The NFIA:RAF1 fusion displayed distinct subcellular localization towards the plasma membrane...

    2009-07-01

    This study evaluated the effectiveness of group psychotherapy in reducing levels of shame and guilt in adult survivors of childhood sexual abuse at risk for HIV, and whether such reductions would mediate the effects of treatment on posttraumatic stress disorder (PTSD) symptoms. One hundred sixty-six women were randomized into 3 conditions: a trauma-focused group, a present-focused group, and a waitlist group. Women received 6 months of treatment and were assessed at pretreatment (T1), immediately posttreatment (T2), and 6 months posttreatment (T3). Both treatment conditions resulted in reduced shame and guilt. The treatment effect on PTSD symptoms was mediated by changes in shame, but it was not associated with changes in guilt. These findings suggest that, when treating childhood sexual abuse survivors' PTSD, it is important to address the negative self-appraisals, such as shame, that commonly accompany such symptoms.

    2015-03-01

    Turner syndrome (TS) is the result of (partial) absence of one X-chromosome. Besides short stature, gonadal dysgenesis and other physical aspects, TS women have typical psychological features. Since psychological effects of androgen exposure in childhood probably are long-lasting, we explored long-term psychological functioning after oxandrolone (Ox) therapy during childhood in adults with TS in terms of neurocognition, quality of life and social-emotional functioning. During the initial study, girls were treated with growth hormone (GH) combined with placebo (Pl), Ox 0.03 mg/kg/day, or Ox 0.06 mg/kg/day from the age of eight, and estrogen from the age of twelve. Sixty-eight women participated in the current double-blinded follow-up study (mean age 24.0 years, mean time since stopping GH/Ox 8.7 years). We found no effects on neurocognition. Concerning quality of life women treated with Ox had higher anxiety levels (STAI 37.4 ± 8.4 vs 31.8 ± 5.0, p=0.002) and higher scores on the depression subscale of the SCL-90-R (25.7 ± 10.7 vs 20.5 ± 4.7, p=0.01). Regarding social-emotional functioning, emotion perception for fearful faces was lower in the Ox-treated patients, without effect on interpersonal behavior. Our exploratory study is the first to suggest that androgen treatment in adolescence possibly has long-term effects on adult quality of life and social-emotional functioning. However, differences are small and clinical implications of our results seem limited. Therefore we would not recommend against the use of Ox in light of psychological consequences.

    Acute pancreatitis is a rare finding in childhood but probably more common than is generally realized. This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. Patients with hereditary pancreatitis are at high risk for pancreatic cancer.

    Rhabdomyosarcoma is the most common soft-tissue sarcoma in children; it can appear in any part of the body. Its biological behavior varies widely, and despite the absence of specific clinical or radiological characteristics, rhabdomyosarcoma should be taken into account in the differential diagnosis of solid tumors in children. This review focuses primarily on the imaging findings and anatomical distribution of the histological subtypes of childhood rhabdomyosarcoma and secondarily on the differential findings in histological studies.

    Schönau, E

    2013-04-01

    The aim of this article is to present the most relevant musculoskeletal complications known to be associated with being overweight or obese in childhood and adolescence in order to help the clinicians and physiotherapists in the diagnostic and management of these patients. Various musculoskeletal problems like slipped capital femoral epiphysis and Blount disease are well-known complications. More recent studies describe the effects of overweight on musculoskeletal pain and controversial influences on fracture rates. Reduced physical activity is a contributing factor in obesity, but also effects bone mineral accrual. Reduced postural stability and increased falls may be the reason for increased fracture rates. Furthermore these data show relevant changes of locomotion studied by gait analysis. Longitudinal kinematic studies may be needed to understand the entire aspect of gait development in overweight children. Obesity is still a serious health problem and has a relevant impact on the development of a child's musculoskeletal system. Obesity affects the locomotor sytem both functionally and structurally. Future studies are necessary to help us better understand the pathophysiology and development of optimal therapeutic strategies.

    Full Text Available While the efficacy of cognitive-behavioral treatment (CBT approaches for childhood functional abdominal pain (FAP is well-established for child outcomes, only a few studies have reported on parent-specific outcomes. This randomized controlled pilot trial analyzed effects of a group CBT on maternal variables (i.e., pain-related behavior, worries and self-efficacy, as well as general psychosocial strain. Methods: The sample constituted of 15 mothers in the intervention group (IG and 14 mothers in the waitlist control group (WLC. Outcome measures were assessed pre-treatment, post-treatment and at three months follow-up. Results: Analyses revealed significant, large changes in maladaptive maternal reactions related to the child’s abdominal pain in the IG compared to the WLC—i.e., reduced attention (d = 0.95, medical help-seeking (d = 0.92, worries (d = 1.03, as well as a significant increase in behaviors that encourage the child’s self-management (d = 1.03. In addition, maternal self-efficacy in dealing with a child’s pain significantly increased in the IG as well (d = 0.92. Treatment effects emerged post-treatment and could be maintained until three months follow-up. There were no effects on general self-efficacy and maternal quality of life. Conclusion: While these results are promising, and underline the efficacy of the CBT approach for both the child and mothers, further studies, including long-term follow-ups, are warranted.

    Full Text Available Abstract Background Astrocytoma is a common aggressive intracranial tumor and presents a formidable challenge in the clinic. Association of altered DNA methylation patterns of the promoter CpG islands with the expression profile of cancer-related genes, has been found in many human tumors. Therefore, DNA methylation status as such may serve as an epigenetic biomarker for both diagnosis and prognosis of human tumors, including astrocytoma. Methods We used the methylation specific PCR in conjunction with sequencing verification to establish the methylation profile of the promoter CpG island of thirty four genes in astrocytoma tissues from fifty three patients (The WHO grading:. I: 14, II: 15, III: 12 and IV: 12 cases, respectively. In addition, compatible tissues (normal tissues distant from lesion from three non-astrocytoma patients were included as the control. Results Seventeen genes (ABL, APC, APAF1, BRCA1, CSPG2, DAPK1, hMLH1, LKB1, PTEN, p14ARF, p15INK4b, p27KIP1, p57KIP2, RASSF1C, RB1, SURVIVIN, and VHL displayed a uniformly unmethylated pattern in all the astrocytoma and non-astrocytoma tissues examined. However, the MAGEA1 gene that was inactivated and hypermethylated in non-astrocytoma tissues, was partially demethylated in 24.5% of the astrocytoma tissues (co-existence of the hypermethylated and demethylated alleles. Of the astrocytoma associated hypermethylated genes, the methylation pattern of the CDH13, cyclin a1, DBCCR1, EPO, MYOD1, and p16INK4a genes changed in no more than 5.66% (3/53 of astrocytoma tissues compared to non-astrocytoma controls, while the RASSF1A, p73, AR, MGMT, CDH1, OCT6,, MT1A, WT1, and IRF7 genes were more frequently hypermethylated in 69.8%, 47.2%, 41.5%, 35.8%, 32%, 30.2%, 30.2%, 30.2% and 26.4% of astrocytoma tissues, respectively.

    O'Grady, M J

    2012-02-01

    Subclinical hypothyroidism (SH) is defined as an elevated thyroid stimulating hormone (TSH) in association with a normal total or free thyroxine (T4) or triiodothyronine (T3). It is frequently encountered in both neonatology and general paediatric practice; however, its clinical significance is widely debated. Currently there is no broad consensus on the investigation and treatment of these patients; specifically who to treat and what cut-off level of TSH should be used. This paper reviews the available evidence regarding investigation, treatments and outcomes reported for childhood SH.

    Cyclophosphamide (CYC) has been the landmark in the treatment of lupus nephritis. However, long-term treatment with CYC is associated with significant side effects. We aimed to evaluate the efficacy of short-term intravenous (IV) CYC treatment as a remission induction treatment followed by azathioprine (AZA) or mycophenolate mofetil (MMF) as a maintenance treatment. Twenty patients (18 girls) with biopsy-proven class III (5) and IV (15) lupus nephritis were included in to the study. Detailed clinical and laboratory data and patient outcomes were evaluated. All patients received three methylprednisolone (MP) IV pulses, followed by oral prednisone 0.5-1 mg/kg per day and one IV pulse of CYC per month for 6 months. Azathioprine was started as a remission-maintaining treatment. In ten of 20 patients, treatment was switched to MMF. The mean age at the time of diagnosis was 16.11 +/- 3.49 years, and the mean duration of follow-up was 49.6 +/- 27 months. Fourteen patients (70%) had complete remission, three (15%) had partial remission, one (5%) continued to have active disease, and two (10%) progressed to end-stage renal disease. Nine of the patients (45%) with complete remission had received AZA, and switching to MMF increased complete remission rate (additional five patients; 25%). In conclusion, short-term (6-month) IV bolus CYC treatment followed by AZA is a safe and effective treatment in children with severe lupus nephritis, and using MMF increases remission rate in resistant cases.

    The study of neurological disorders often presents with significant challenges due to the inaccessibility of human neuronal cells for further investigation. Advances in cellular reprogramming techniques, have however provided a new source of human cells for laboratory-based research. Patient-derived induced pluripotent stem cells (iPSCs) can now be robustly differentiated into specific neural subtypes, including dopaminergic, inhibitory GABAergic, motorneurons and cortical neurons. These neurons can then be utilized for in vitro studies to elucidate molecular causes underpinning neurological disease. Although human iPSC-derived neuronal models are increasingly regarded as a useful tool in cell biology, there are a number of limitations, including the relatively early, fetal stage of differentiated cells and the mainly two dimensional, simple nature of the in vitro system. Furthermore, clonal variation is a well-described phenomenon in iPSC lines. In order to account for this, robust baseline data from multiple control lines is necessary to determine whether a particular gene defect leads to a specific cellular phenotype. Over the last few years patient-derived neural cells have proven very useful in addressing several mechanistic questions related to central nervous system diseases, including early-onset neurological disorders of childhood. Many studies report the clinical utility of human-derived neural cells for testing known drugs with repurposing potential, novel compounds and gene therapies, which then can be translated to clinical reality. iPSCs derived neural cells, therefore provide great promise and potential to gain insight into, and treat early-onset neurological disorders.

  5. The expression level of CB1 and CB2 receptors determines their efficacy at inducing apoptosis in astrocytomas.

    Directory of Open Access Journals (Sweden)

    Eiron Cudaback

    Full Text Available BACKGROUND: Cannabinoids represent unique compounds for treating tumors, including astrocytomas. Whether CB(1 and CB(2 receptors mediate this therapeutic effect is unclear. PRINCIPAL FINDINGS: We generated astrocytoma subclones that express set levels of CB(1 and CB(2, and found that cannabinoids induce apoptosis only in cells expressing low levels of receptors that couple to ERK1/2. In contrast, cannabinoids do not induce apoptosis in cells expressing high levels of receptors because these now also couple to the prosurvival signal AKT. Remarkably, cannabinoids applied at high concentration induce apoptosis in all subclones independently of CB(1, CB(2 and AKT, but still through a mechanism involving ERK1/2. SIGNIFICANCE: The high expression level of CB(1 and CB(2 receptors commonly found in malignant astrocytomas precludes the use of cannabinoids as therapeutics, unless AKT is concomitantly inhibited, or cannabinoids are applied at concentrations that bypass CB(1 and CB(2 receptors, yet still activate ERK1/2.

    Full Text Available Background. The synchronous development of two primary brain tumors of distinct cell of origin in close proximity or in contact with each other is extremely rare. We present the first case of collision tumor with two histological distinct tumors. Case Presentation. A 54-year-old woman presented with progressive atypical left facial pain and numbness for 8 months. MRI of the brain showed left middle cranial fossa heterogeneous mass extending into the infratemporal fossa. At surgery, a distinct but intermingled intra- and extradural tumor was demonstrated which was completely removed through left orbitozygomatic-temporal craniotomy. Histopathological examination showed that the tumor had two distinct components: malignant nerve sheath tumor of the trigeminal nerve and temporal lobe anaplastic astrocytoma. Proliferative activity and expressed tumor protein 53 (TP53 gene mutations were demonstrated in both tumors. Conclusions. We describe the first case of malignant trigeminal nerve sheath tumor (MTNST and anaplastic astrocytoma in collision and discuss the possible hypothesis of this rare occurrence. We propose that MTNST, with TP53 mutation, have participated in the formation of anaplastic astrocytoma, or vice versa.

    Sun exposure in both childhood and adult life represents the main environmental risk determinant for cutaneous melanoma. However, little is known about the joint effects of sun exposure during early and later life on melanoma risk. A case-control study in Belgium, Germany and France conducted in 1991-1992 suggests that the melanoma risks attached to indicators related to sun exposure appear to combine their effects in an additive way. We therefore constructed composite indices of sun exposure during childhood and during adulthood, assuming additive combinations of melanoma risk associated with each indicator of sun exposure. Logistic regression modeling showed that the melanoma risk associated with a given level of sun exposure during adulthood increased with higher sun exposure during childhood, but the increase in risk was higher than the simple addition of melanoma risk associated with sun exposure during childhood or adulthood. In turn, high sun exposure during childhood constituted a significant risk factor for melanoma only if there was substantial sun exposure during adult life. We thus suggest that sun exposure during childhood and during adulthood would be interdependent as far as their impact on melanoma risk is concerned. Our results support the hypothesis by which the important contribution of sun exposure during childhood in melanoma occurrence is not properly assessed by retrospective epidemiologic studies. Sun avoidance during childhood would have a greater impact on melanoma risk than sun avoidance during adulthood.

    CIL-102 (1-[4-(furo[2,3-b]quinolin-4-ylamino)phenyl]ethanone) is the major active agent of the alkaloid derivative of Camptotheca acuminata, with multiple pharmacological activities, including anticancer effects and promotion of apoptosis. The mechanism by which CIL-102 inhibits growth remains poorly understood in human astrocytoma cells. Herein, we investigated the molecular mechanisms by which CIL-102 affects the generation of reactive oxygen species (ROS) and cell cycle G2/M arrest in glioma cells. Treatment of U87 cells with 1.0 μM CIL-102 resulted in phosphorylation of extracellular signal-related kinase (ERK1/2), downregulation of cell cycle-related proteins (cyclin A, cyclin B, cyclin D1, and cdk1), and phosphorylation of cdk1Tyr{sup 15} and Cdc25cSer{sup 216}. Furthermore, treatment with the ERK1/2 inhibitor PD98059 abolished CIL-102-induced Cdc25cSer{sup 216} expression and reversed CIL-102-inhibited cdk1 activation. In addition, N-acetyl cysteine (NAC), an ROS scavenger, blocked cell cycle G2/M arrest and phosphorylation of ERK1/2 and Cdc25cSer{sup 216} in U87 cells. CIL-102-mediated ERK1/2 and ROS production, and cell cycle arrest were blocked by treatment with specific inhibitors. In conclusion, we have identified a novel CIL-102-inhibited proliferation in U87 cells by activating the ERK1/2 and Cdc25cSer{sup 216} cell cycle-related proteins and inducing ROS production; this might be a new mechanism in human astrocytoma cells. -- Highlights: ► We show the effects of CIL-102 on the G2/M arrest of human astrocytoma cells. ► ROS and the Ras/ERK1/2 triggering pathways are involved in the CIL-102 treatment. ► CIL-102 induces sustained activation of ERK1/2 and Cdc25c and ROS are required.

    We compared three treatments: sodium cromoglycate 5 mg aerosol and placebo syrup (39 patients), placebo aerosol and ketotifen syrup (39 patients), and placebo aerosol and syrup (36 patients). The patients (mean age 11.7 years) had mostly allergic, moderately severe asthma. Treatments were added to current therapy (mostly bronchodilators only) for 3 months. Aerosols were taken four times daily and syrups twice daily. The following results were significant at a level of 5%. At the final clinic visit, the changes from baseline in lung function favored sodium cromoglycate over the other treatments. During month 3, sodium cromoglycate was superior to ketotifen for night symptoms, morning tightness, daytime symptoms, and cough. Bronchodilator use decreased more with sodium cromoglycate than ketotifen. Patients' and clinicians' overall opinions of treatment effectiveness favored sodium cromoglycate over ketotifen and placebo. In these patients, sodium cromoglycate was both effective and superior to ketotifen.

    To determine the receipt and impact of adjuvant therapy on overall survival (OS) for anaplastic astrocytoma (AA). Data were extracted from the National Cancer Data Base (NCDB). Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 4807 patients with AA diagnosed from 2004 to 2013 who underwent surgery were identified. 3243 (67.5 %) received adjuvant chemoRT, 525 (10.9 %) adjuvant radiotherapy (RT) alone, 176 (3.7 %) adjuvant chemotherapy alone and 863 (18.0 %) received no adjuvant therapy. Patients were more likely to receive adjuvant chemoRT if they were diagnosed in 2009-2013 (p = 0.022), were ≤ 50 years (p < 0.001), were male (p = 0.043), were Asian or White race (p < 0.001), had private insurance (p < 0.001), had income ≥$38,000 (p < 0.001), or underwent total resection (p < 0.003). Those who received adjuvant chemoRT had significantly better 5-year OS than the other adjuvant treatment types (41.8 % vs. 31.2 % vs. 29.8 % vs. 27.4 %, p < 0.001). This significant 5-year OS benefit was also observed regardless of age at diagnosis. Of those undergoing adjuvant chemoRT, those receiving ≥59.4 Gy had significantly better 5-year OS than those receiving <59.4 Gy (44.4 % vs. 25.9 %, p < 0.001). There was no significant difference in OS when comparing 59.4 Gy to higher RT doses. On multivariate analysis, receipt of adjuvant chemoRT, age at diagnosis, extent of disease, and insurance status were independent prognostic factors for OS. Adjuvant chemoRT is an independent prognostic factor for improved OS in AA and concomitant chemoRT should be considered for all clinically suitable patients who have undergone surgery for the disease.

  12. Superoxide anion radical (O2(-)) degrades methylmercury to inorganic mercury in human astrocytoma cell line (CCF-STTG1).

    Methylmercury (MeHg) is a global pollutant that is affecting the health of millions of people worldwide. However, the mechanism of MeHg toxicity still remains somewhat elusive and there is no treatment. It has been known for some time that MeHg can be progressively converted to inorganic mercury (iHg) in various tissues including the brain. Recent work has suggested that cleavage of the carbon-metal bond in MeHg in a biological environment is facilitated by reactive oxygen species (ROS). However, the oxyradical species that actually mediates this process has not been identified. Here, we provide evidence that superoxide anion radical (O2(-)) can convert MeHg to iHg. The calculated second-order rate constant for the degradation of 1μM MeHg by O2(-) generated by xanthine/xanthine oxidase was calculated to be 2×10(5)M(-1)s(-1). We were also able to show that this bioconversion can proceed in intact CCF-STTG1 human astrocytoma cells exposed to paraquat (PQ), a O2(-) generating viologen. Notably, exposure of cells to increasing amounts of PQ led to a dose dependent increase in both MeHg and iHg. Indeed, a 24h exposure to 500μM PQ induced a ∼13-fold and ∼18-fold increase in intracellular MeHg and iHg respectively. These effects were inhibited by superoxide dismutase mimetic MnTBAP. In addition, we also observed that a 24h exposure to a biologically relevant concentration of MeHg (1μM) did not induce cell death, oxidative stress, or even changes in cellular O2(-) and H2O2. However, co-exposure to PQ enhanced MeHg toxicity which was associated with a robust increase in cell death and oxidative stress. Collectively our results show that O2(-) can bioconvert MeHg to iHg in vitro and in intact cells exposed to conditions that simulate high intracellular O2(-) production. In addition, we show for the first time that O2(-) mediated degradation of MeHg to iHg enhances the toxicity of MeHg by facilitating an accumulation of both MeHg and iHg in the intracellular

    Inhibition of fear generalization with new learning is an important process in treatments for anxiety disorders. Generalization of maladaptive cognitions related to traumatic experiences (overgeneralized beliefs) have been demonstrated to be associated with posttraumatic stress disorder (PTSD) in adult populations, whereas more balanced, accommodated beliefs are associated with symptom improvement. It is not yet clear whether (a) overgeneralization and accommodation are associated with PTSD treatment outcome in youth, or (b whether accommodated beliefs can interact with or inhibit cognitive overgeneralization, as has been demonstrated in research on behavior-based fear generalization. The current study examined the relationships between overgeneralized and accommodated beliefs, child age, and symptom reduction in a sample of 81 youth (age 7-17 years), who received Trauma-Focused Cognitive Behavioral Therapy. Overgeneralized and accommodated beliefs expressed during the exposure phase of treatment were coded in audio-recorded therapy sessions. Overgeneralization predicted (a) higher internalizing symptom scores at posttreatment, particularly for younger children, and less improvement over treatment, and (b) higher externalizing scores at 1-year follow-up and steeper symptom increases over this period. In contrast, accommodation was associated with (a) lower posttreatment internalizing symptoms and greater improvement over treatment, and (b) lower externalizing scores at 1-year follow-up, particularly for younger children. High levels of accommodation moderated the relationship between overgeneralization and worse symptom outcomes, except when predicting the slope of internalizing scores over treatment, and age did not moderate these effects. There were no significant predictors of child-reported PTSD-specific symptoms, although PTSD symptoms did decrease significantly over the course of treatment and maintain 1year after treatment.

    This study examined the relative importance of climate change and drinking-water treatment for gastrointestinal illness incidence in children (age climate change and drinking-water treatment installation may alter gastrointestinal illness incidence. Future precipitation values were modeled by 13 global climate models and three greenhouse-gas emissions levels. The second analysis was rerun using three pathways: (1) only climate change, (2) climate change and the same slow pace of treatment installation observed over 1991-2010, and (3) climate change and the rapid rate of installation observed over 2011-2016. The results illustrate the risks that climate change presents to small rural groundwater municipalities without drinking water treatment. Climate-change-related seasonal precipitation changes will marginally increase the gastrointestinal illness incidence rate (mean: ˜1.5%, range: -3.6-4.3%). A slow pace of treatment installation somewhat decreased precipitation-associated gastrointestinal illness incidence (mean: ˜3.0%, range: 0.2-7.8%) in spite of climate change. The rapid treatment installation rate largely decreases the gastrointestinal illness incidence (mean: ˜82.0%, range: 82.0-83.0%).

    Our aim was to investigate the expression of micro-RNA-200b (miR-200b) and cAMP-responsive element-binding protein 1 (CREB-1) in astrocytoma and its efficacy for predicting outcome. Both miR-200b and CREB-1 messenger RNA expression was measured in 122 astrocytomas and 30 nonneoplastic brain specimens by quantitative real-time polymerase chain reaction. Expression of miR-200b was significantly lower in astrocytoma than in nonneoplastic brain (P RNA expression was significantly elevated in the tumors (P < .001). Both miR-200b down-regulation and CREB-1 up-regulation were significantly associated with advanced pathologic grade (P = .002 and P = .006, respectively). Low miR-200b expression correlated negatively with Karnofsky performance score (P = .03), and high CREB-1 expression correlated positively with mean tumor diameter (P = .03). By Kaplan-Meier analysis, low miR-200b, high CREB-1, and coexistence of abnormal miR-200b and CREB-1 expression (low miR-200b/high CREB-1) were predictive of shorter progression-free survival and overall survival in both grade III and grade IV astrocytoma. By multivariate analysis, only low miR-200b/high CREB-1 expression was an independent prognostic factor for poor prognosis in astrocytoma of advanced grade. Both miR-200b and CREB-1 may play important cooperative roles in the progression of human astrocytoma. The efficacy of miR-200b and CREB-1 together as a predictor of prognosis in astrocytoma patients is shown for the first time.

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

    Phase contrast and epifluorescence microscopy were utilized to monitor morphological changes in human astrocytoma cells during a time-course exposure to single-walled carbon nanotube (SWCNT) conjugates with different surfactants and to investigate sub-cellular distribution of the nanotube conjugates, respectively. Experimental results demonstrate that cytotoxicity of the nanotube/surfactant conjugates is related to the toxicity of surfactant molecules attached on the nanotube surfaces. Both sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (SDBS) are toxic to cells. Exposure to CNT/SDS conjugates (0.5 mg/mL) for less than 5 min caused changes in cell morphology resulting in a distinctly spherical shape compared to untreated cells. In contrast, sodium cholate (SC) and CNT/SC did not affect cell morphology, proliferation, or growth. These data indicate that SC is an environmentally friendly surfactant for the purification and dispersion of SWCNTs. Epifluorescence microscopy analysis of CNT/DNA conjugates revealed distribution in the cytoplasm of cells and did not show adverse effects on cell morphology, proliferation, or viability during a 72-h incubation. These observations suggest that the SWCNTs could be used as non-viral vectors for diagnostic and therapeutic molecules across the blood-brain barrier to the brain and the central nervous system.

    Full Text Available A retrospective study of 81 patients with low-grade astrocytoma (LGA comparing the efficacy of aggressive versus less aggressive surgery in eloquent and non-eloquent brain areas was conducted. Extent of surgical resection was analyzed to assess overall survival (OS and progression- free survival (PFS. Degree of tumor resection was classified as gross total resection (GTR, subtotal resection (STR or biopsy. GTR, STR and biopsy in patients with tumors in non-eloquent areas were performed in 31, 48 and 21% subjects, whereas in patients with tumors in eloquent areas resections were 22.5, 35 and 42.5%. Overall survival was 4.7 and 1.9 years in patients with tumors in non-eloquent brain areas submitted to GTR/STR and biopsy (p=0.013, whereas overall survival among patients with tumors in eloquent area was 4.5 and 2.1 years (p=0.33. Improved outcome for adult patients with LGA is predicted by more aggressive surgery in both eloquent and non-eloquent brain areas.

    Full Text Available Abstract Background Malignant gliomas recur even after extensive surgery and chemo-radiotherapy. Although a relatively novel chemotherapeutic agent, temozolomide (TMZ, has demonstrated promising activity against recurrent glioma, the effects last only a few months and drug resistance develops thereafter in most cases. Induction of O6-methylguanine-DNA methyltransferase (MGMT in tumors is considered to be responsible for resistance to TMZ. Interferon-beta has been reported to suppress MGMT in an experimental glioma model. Here we report a patient with TMZ-refractory anaplastic astrocytoma (AA who was treated successfully with a combination of interferon-beta and TMZ. Case presentation A patient with recurrent AA after radiation-chemotherapy and stereotactic radiotherapy was treated with TMZ. After 6 cycles, the tumor became refractory to TMZ, and the patient was treated with interferon-beta at 3 × 106 international units/body, followed by 5 consecutive days of 200 mg/m2 TMZ in cycles of 28 days. After the second cycle the tumor decreased in size by 50% (PR. The tumor showed further shrinkage after 8 months and the patient's KPS improved from 70% to 100%. The immunohistochemical study of the initial tumor specimen confirmed positive MGMT protein expression. Conclusion It is considered that interferon-beta pre-administration increased the TMZ sensitivity of the glioma, which had been refractory to TMZ monotherapy.

    Reports describing a rapid increase in the cystic volume of anaplastic astrocytoma (AA) in a short time frame are rare. The present study reports the case of a 68-year-old male who was admitted to the No. 9 People's Hospital, Shanghai Jiaotong University School of Medicine (Shanghai, China), with a small cystic brain lesion and positive immunological testing for cysticercosis. Head magnetic resonance imaging (MRI) showed a cystic lesion, 6 mm in diameter, in the left frontal lobe. Neurocysticercosis was suspected and the patient was treated with a clinical trial of albendazole and steroids. A period of 25 days later, the patient's condition had deteriorated, and MRI revealed a cystic lesion in the left frontal lobe; thereafter, the cystic lesion was removed and a diagnosis of AA was established. The tumor was soft, ivory white and gelatinous due to myxoid degeneration. In this case, tumor-related angiogenesis and microvascular extravasation (blood-brain barrier disruption) may have been the main cause of the rapid increase in the cystic volume in such a short time frame. The similarity of the glioma and cysticercus antigens may have been the cause of the positive reactions in the cystic fluid. The present study reports the rare occurrence of a rapid increase of cystic volume and potential diagnostic difficulties. PMID:27698865

    Patient satisfaction represents a significant outcome criterion in the context of systemic psychotherapeutic therapy research. This study investigated parent satisfaction with a psychosocial treatment program (comprising three components: child group therapy, parents' evenings, systemic family sessions) for pediatric primary headache (diagnosed according to IHS criteria). 10 weeks after the end of the treatment program, the parents were sent a questionnaire containing open questions and ten-point numerical rating scales. The sample comprised n=48 families. The return rate was 89%. The qualitative content analysis showed a hierarchical category system consisting of 3 major categories, 7 main groups and 69 sub-categories. The parents stated that they were satisfied with (1.) the effects of the treatment program, (2.) the specific treatment techniques and the medical and psychosocial headache-related information provided, and (3.) the therapeutic relationship. The mean satisfaction for all three therapy components on the ten-point numerical rating scale was 8.1 with a standard deviation of 2.0 (child headache group: 8.5; parents' evenings: 8.2; family sessions: 7.5). The results are discussed with reference to methodological aspects: avoidance of ceiling effects and social desirability in measuring customer satisfaction, order effects of items, weighting of the significance of satisfaction levels as an outcome criterion.

    Full Text Available Abstract Background Malaria remains a major cause of morbidity and mortality among children under five years of age in Nigeria. Most of the early treatments for fever and malaria occur through self-medication with anti-malarials bought over-the-counter (OTC from untrained drug vendors. Self-medication through drug vendors can be ineffective, with increased risks of drug toxicity and development of drug resistance. Global malaria control initiatives highlights the potential role of drug vendors to improve access to early effective malaria treatment, which underscores the need for interventions to improve treatment obtained from these outlets. This study aimed to determine the feasibility and impact of training rural drug vendors on community-based malaria treatment and advice with referral of severe cases to a health facility. Methods A drug vendor-training programme was carried out between 2003 and 2005 in Ugwuogo-Nike, a rural community in south-east Nigeria. A total of 16 drug vendors were trained and monitored for eight months. The programme was evaluated to measure changes in drug vendor practice and knowledge using exit interviews. In addition, home visits were conducted to measure compliance with referral. Results The intervention achieved major improvements in drug selling and referral practices and knowledge. Exit interviews confirmed significant increases in appropriate anti-malarial drug dispensing, correct history questions asked and advice given. Improvements in malaria knowledge was established and 80% compliance with referred cases was observed during the study period, Conclusion The remarkable change in knowledge and practices observed indicates that training of drug vendors, as a means of communication in the community, is feasible and strongly supports their inclusion in control strategies aimed at improving prompt effective treatment of malaria with referral of severe cases.

    2013-01-01

    The literature on child sexual abuse reflects growing recognition of the manner in which culture impacts the conceptualization, experience, and treatment of such cases. Despite heightened visibility of Arab Americans within the United States, population due to recent media attention, little empirical research exists on the occurrence of child sexual abuse within this population. Arab culture is often characterized by an emphasis on collectivism and familial obligations, and such features may prove to either facilitate or impede assessment and treatment of child sexual abuse, depending on how they are manifested. In terms of reporting child sexual abuse, cultural values pertaining to shame and honor as well as the stigma attached to mental health problems may influence the response to abuse. As such, enhancing the cultural competence of the therapist is key to facilitating effective cultural practice. Empirical research is required to investigate and substantiate these concepts as they relate to child sexual abuse in Arab-American populations.

    Pediatric posterior fossa (PF) tumor survivors experience long-term motor deficits. Specific cerebrocerebellar connections may be involved in incidence and severity of motor dysfunction. We examined the relationship between long-term ataxia as well as fine motor function and alteration of differential cerebellar efferent and afferent pathways using diffusion tensor imaging (DTI) and tractography. DTI-based tractography was performed in 19 patients (10 pilocytic astrocytoma (PA) and 9 medulloblastoma patients (MB)) and 20 healthy peers. Efferent Cerebello-Thalamo-Cerebral (CTC) and afferent Cerebro-Ponto-Cerebellar (CPC) tracts were reconstructed and analyzed concerning fractional anisotropy (FA) and volumetric measurements. Clinical outcome was assessed with the International Cooperative Ataxia Rating Scale (ICARS). Kinematic parameters of fine motor function (speed, automation, variability, and pressure) were obtained by employing a digitizing graphic tablet. ICARS scores were significantly higher in MB patients than in PA patients. Poorer ICARS scores and impaired fine motor function correlated significantly with volume loss of CTC pathway in MB patients, but not in PA patients. Patients with pediatric post-operative cerebellar mutism syndrome showed higher loss of CTC pathway volume and were more atactic. CPC pathway volume was significantly reduced in PA patients, but not in MB patients. Neither relationship was observed between the CPC pathway and ICARS or fine motor function. There was no group difference of FA values between the patients and healthy peers. Reduced CTC pathway volumes in our cohorts were associated with severity of long-term ataxia and impaired fine motor function in survivors of MBs. We suggest that the CTC pathway seems to play a role in extent of ataxia and fine motor dysfunction after childhood cerebellar tumor treatment. DTI may be a useful tool to identify relevant structures of the CTC pathway and possibly avoid surgically induced long

    Background The prevalence of targeted and serendipitous treatment for, and associated recovery from, urinary tract infection (UTI) in pre-school children is unknown. Aim To determine the frequency and suspicion of UTI in children who are acutely ill, along with details of antibiotic prescribing, its appropriateness, and whether that appropriateness impacted on symptom improvement and recovery. Design and setting Prospective observational cohort study in primary care sites in urban and rural areas in England and Wales. Method Systematic urine sampling from children aged <5years presenting in primary care with acute illness with culture in NHS laboratories. Results Of 6079 children’s urine samples, 339 (5.6%) met laboratory criteria for UTI and 162 (47.9%) were prescribed antibiotics at the initial consultation. In total, 576/7101 (8.1%) children were suspected of having a UTI prior to urine sampling, including 107 of the 338 with a UTI (clinician sensitivity 31.7%). Children with a laboratory-diagnosed UTI were more likely to be prescribed antibiotics when UTI was clinically suspected than when it was not (86.0% versus 30.3%, P<0.001). Of 231 children with unsuspected UTI, 70 (30.3%) received serendipitous antibiotics (that is, antibiotics prescribed for a different reason). Overall, 176 (52.1%) children with confirmed UTI did not receive any initial antibiotic. Organism sensitivity to the prescribed antibiotic was higher when UTI was suspected than when treated serendipitously (77.1% versus 26.0%; P<0.001). Children with UTI prescribed appropriate antibiotics at the initial consultation improved a little sooner than those with a UTI who were not prescribed appropriate antibiotics initially (3.5 days versus 4.0 days; P = 0.005). Conclusion Over half of children with UTI on culture were not prescribed antibiotics at first presentation. Serendipitous UTI treatment was relatively common, but often inappropriate to the organism’s sensitivity. Methods for improved

    Full Text Available Abstract Background Millions of children die every year in developing countries, from preventable diseases such as pneumonia and diarrhoea, owing to low levels of investment in child health. Investment efforts are hampered by a general lack of adequate information that is necessary for priority setting in this sector. This paper measures the health system costs of providing inpatient and outpatient services, and also the costs associated with treating pneumonia and diarrhoea in under-five children at a health centre in Zambia. Methods Annual economic and financial cost data were collected in 2005-2006. Data were summarized in a Microsoft excel spreadsheet to obtain total department costs and average disease treatment costs. Results The total annual cost of operating the health centre was US$1,731,661 of which US$1 284 306 and US$447,355 were patient care and overhead departments costs, respectively. The average cost of providing out-patient services was US$3 per visit, while the cost of in-patient treatment was US$18 per bed day. The cost of providing dental services was highest at US$20 per visit, and the cost of VCT services was lowest, with US$1 per visit. The cost per out-patient visit for under-five pneumonia was US$48, while the cost per bed day was US$215. The cost per outpatient visit attributed to under-five diarrhoea was US$26, and the cost per bed day was US$78. Conclusion In the face of insufficient data, a cost analysis exercise is a difficult but feasible undertaking. The study findings are useful and applicable in similar settings, and can be used in cost effectiveness analyses of health interventions.

    Glioblastoma, the most aggressive type of primary brain tumour, shows worse prognosis linked to diabetes or obesity persistence. These pathologies are chronic inflammatory conditions characterized by altered profiles of inflammatory mediators, including leptin and secreted phospholipase A2-IIA (sPLA2-IIA). Both proteins, in turn, display diverse pro-cancer properties in different cell types, including astrocytes. Herein, to understand the underlying relationship between obesity and brain tumors, we investigated the effect of leptin, alone or in combination with sPLA2-IIA on astrocytoma cell functions. sPLA2-IIA induced up-regulation of leptin receptors in 1321N1 human astrocytoma cells. Leptin, as well as sPLA2-IIA, increased growth and migration in these cells, through activation/phosphorylation of key proteins of survival cascades. Leptin, at concentrations with minimal or no activating effects on astrocytoma cells, enhanced growth and migration promoted by low doses of sPLA2-IIA. sPLA2-IIA alone induced a transient phosphorylation pattern in the Src/ERK/Akt/mTOR/p70S6K/rS6 pathway through EGFR transactivation, and co-addition of leptin resulted in a sustained phosphorylation of these signaling regulators. Mechanistically, EGFR transactivation and tyrosine- and serine/threonine-protein phosphatases revealed a key role in this leptin-sPLA2-IIA cross-talk. This cooperative partnership between both proteins was also found in primary astrocytes. These findings thus indicate that the adipokine leptin, by increasing the susceptibility of cells to inflammatory mediators, could contribute to worsen the prognosis of tumoral and neurodegenerative processes, being a potential mediator of some obesity-related medical complications.

    Full Text Available BACKGROUND: Zinc treatment shortens diarrhea episodes and can prevent future episodes. In rural Africa, most children with diarrhea are not brought to health facilities. In a village-randomized trial in rural Kenya, we assessed if zinc treatment might have a community-level preventive effect on diarrhea incidence if available at home versus only at health facilities. METHODS: We randomized 16 Kenyan villages (1,903 eligible children to receive a 10-day course of zinc and two oral rehydration solution (ORS sachets every two months at home and 17 villages (2,241 eligible children to receive ORS at home, but zinc at the health-facility only. Children's caretakers were educated in zinc/ORS use by village workers, both unblinded to intervention arm. We evaluated whether incidence of diarrhea and acute lower respiratory illness (ALRI reported at biweekly home visits and presenting to clinic were lower in zinc villages, using poisson regression adjusting for baseline disease rates, distance to clinic, and children's age. RESULTS: There were no differences between village groups in diarrhea incidence either reported at the home or presenting to clinic. In zinc villages (1,440 children analyzed, 61.2% of diarrheal episodes were treated with zinc, compared to 5.4% in comparison villages (1,584 children analyzed, p<0.0001. There were no differences in ORS use between zinc (59.6% and comparison villages (58.8%. Among children with fever or cough without diarrhea, zinc use was low (<0.5%. There was a lower incidence of reported ALRI in zinc villages (adjusted RR 0.68, 95% CI 0.46-0.99, but not presenting at clinic. CONCLUSIONS: In this study, home zinc use to treat diarrhea did not decrease disease rates in the community. However, with proper training, availability of zinc at home could lead to more episodes of pediatric diarrhea being treated with zinc in parts of rural Africa where healthcare utilization is low.

    It is currently unclear whether adjuvant therapy for WHO grade III anaplastic astrocytomas (AA) should be carried out as combined chemoradiotherapy with temozolomide (TMZ) - analogous to the approach for glioblastoma multiforme - or as radiotherapy (RT) alone. A retrospective analysis of data from 90 patients with AA, who were treated between November 1997 and February 2014. Assessment of overall (OS) and progression-free survival (PFS) was performed according to treatment categories: (1) 50 %, RT + TMZ according to protocol, (2) 11 %, RT + TMZ with dose reduction, (3) 26 %, RT alone, and (4) 13 %, individualized, primarily palliative therapy. No dose reduction was necessary in the RT alone group. Median OS was 85, 69, and 43 months for treatment categories 1/2, 3, and 4, respectively. These differences were not statistically significant. PFS was 35, 29, 48, and 33 months for categories 1, 2, 3, and 4, respectively; again without significant differences between categories. In a subgroup of 39 patients with known IDH1 R132H status, the presence of this mutation correlated with significantly longer OS (p = 0.01) and PFS (p = 0.002). Complete or partial tumor resection and younger age also correlated with a significantly better prognosis, and this influence persisted in multivariate analysis. In the IDH1 R132H subgroup analysis, only this marker retained an independent prognostic value. A general superiority of combined chemoradiotherapy compared to RT alone could not be demonstrated. Biomarkers for predicting the benefits of combination therapy using RT and TMZ are needed for patients with AA. (orig.) [German] Es ist derzeit unklar, ob bei anaplastischen Astrozytomen (AA) vom WHO-Grad III eine adjuvante Therapie analog zur Therapiestrategie beim Glioblastoma multiforme als kombinierte Radiochemotherapie mit Temozolomid (TMZ) oder als alleinige Radiotherapie (RT) durchgefuehrt werden sollte. Retrospektiv wurden die Daten von 90 Patienten mit AA, die zwischen November

    Fatty liver is a growing health problem worldwide. It might evolve to nonalcoholic steatohepatitis, cirrhosis and cause hepatocellular carcinoma. This disease, which has increased because of eating habits, changes in food content and lifestyle, affects people from childhood. The most important risk factors are obesity and insulin resistance. Besides these factors, gender, ethnicity, genetic predisposition and some medical problems are also important. Cirrhosis in children is rare but is reported. Nonalcoholic fatty liver disease(NAFLD) has no specific symptoms or signs but should be considered in obese children. NAFLD does not have a proven treatment. Weight loss with family based treatments is the most acceptable management. Exercise and an applicable diet with low glycemic index and appropriate calorie intake are preferred. Drugs are promising but not sufficient in children for today.

    Cancer is the most common fatal disease among US children. The fetus has reduced resistance to toxic injury and is especially prone to mutagenic injury because of the high rate of cell division. A fetus can be exposed to environmental toxins through maternal consumption of contaminated water. The objective of this study was to estimate the incidence risk for childhood cancers within each watershed in Texas. The approach modeled risk for 19 cancer histotypes incorporating correlations among the cancer types and spatial correlation. Several watersheds in a very large area known as the Central Great Plains of North Texas were associated with increased risk for astrocytoma. Two watersheds near Houston, Buffalo-San Jacinto and West Galveston Bay, had increased risk for renal cancer and acute lymphoid leukemia, respectively. A watershed in South Texas, the South Laguna Madre, had increased risk for atypical leukemias. The possibility that waterborne toxins cause these childhood cancers should be investigated further.

    Although the majority of children with acute lymphoblastic leukemia (ALL) can electively stop treatment after 2 1/2-5 years of continuous disease-free remission, 20-25% of those patients relapse after discontinuation of therapy. We treated 15 patients whose disease recurred after stopping treatment. Fourteen of them attained complete remission, but the median duration of disease-free survival was only 11 months. In this population, the site of initial relapse, bone marrow or testicle, did not influence subsequent outcome. Patients who relapsed within six months of stopping initial therapy had shorter second remissions than those who relapsed after six months. We conclude that the combination chemotherapy utilized in this study was inadequate for the control of relapsed ALL. Future programs will have to use different drug combinations or bone marrow transplantation.

    Personality disorders manifest themselves in stable deviations of personality traits that especially arise in negative interactions with others. Those typical dysfunctional interactions can be observed particularly in dissocial and antisocial personality disorders: adults with severe forms of personality disorders often showed specific symptoms in childhood and adolescence. Clinical researchers therefore demand a respective diagnosis of childhood and adolescent psychopathy. There is an extensive body of research on dissocial and borderline personality disorders in children and adolescents. To date the severe form of dissocial personality disorders, psychopathy, cannot be specifically classified. The transfer of this diagnosis to childhood and adolescence is crucial: based on the assumption of persistence and the risk of stigmatisation many clinicians refuse to diagnose psychopathy at a young age. On the other hand there are positive treatment outcomes that aim at symptom reduction from a very early age. The specification of dissocial personality disorders in childhood and adolescence may encourage the development of new treatments and the de-stigmatisation as well as qualify the dogged assumption of persistence of personality disorders.

    Purpose: Diffusion tensor imaging (DTI) can measure molecular mobility at the cellular level, quantified by the apparent diffusion coefficient (ADC). DTI may also reveal axonal fiber directional information in the white matter, quantified by the fractional anisotropy (FA). Juvenile pilocytic astrocytoma (JPA) is a rare brain tumor that occurs in children and young adults. Proton therapy (PT) is increasingly used in the treatment of pediatric brain tumors including JPA. However, the response of both tumors and normal tissues to PT is currently under investigation. We report tumor and normal brain tissue responses for a pediatric case of JPA treated with PT assessed using DTI. Methods: A ten year old male with JPA of the left thalamus received passive scattered PT to a dose of 50.4 Gy (RBE) in 28 fractions. Post PT, the patient has been followed up in seven years. At each follow up, MRI imaging including DTI was performed to assess response. MR images were registered to the treatment planning CT and the GTV mapped onto each MRI. The GTV contour was then mirrored to the right side of brain through the patient’s middle line to represent normal brain tissue. ADC and FA were measured within the ROIs. Results: Proton therapy can completely spare contra lateral brain while the target volume received full prescribed dose. From a series of MRI ADC images before and after PT at different follow ups, the enhancement corresponding to GTV had nearly disappeared more than 2 years after PT. Both ADC and FA demonstrate that contralateral normal brain tissue were not affect by PT and the tumor volume reverted to normal ADC and FA values. Conclusion: DTI allowed quantitative evaluation of tumor and normal brain tissue responses to PT. Further study in a larger cohort is warranted.

    Glutathione (GSH) plays a critical role in protecting cells from oxidative damage. Since neurons rely on the supply of GSH from astrocytes to maintain optimal intracellular GSH concentrations, the GSH concentration of astrocytes is important for the survival of neighboring neurons against oxidative stress. The neurotransmitter noradrenaline is known to modulate the functions of astrocytes and has been suggested to have neuroprotective properties in neurodegenerative diseases. To elucidate the mechanisms underlying the neuroprotective properties of noradrenaline, in this study, we investigated the effect of noradrenaline on the concentrations of intracellular GSH in human U-251 malignant glioma (MG; astrocytoma) cells. Treatment of the cells with noradrenaline for 24h concentration-dependently increased their intracellular GSH concentration. This increase was inhibited by a non-selective β-adrenoceptor antagonist propranolol and by a selective β3-adrenoceptor antagonist SR59230A, but not by a non-selective α-adrenoceptor antagonist phenoxybenzamine, or by a selective β1-adrenoceptor antagonist atenolol or by a selective β2-adrenoceptor antagonist butoxamine. In addition, the selective β3-adrenoceptor agonist CL316243 increased the intracellular GSH in U-251 MG cells. Treatment of the cells with noradrenaline (10μM) for 24h increased the protein level of the catalytic subunit of glutamate-cysteine ligase (GCLc), the rate-limiting enzyme of GSH synthesis; and this increase was inhibited by SR59230A. These results thus suggest that noradrenaline increased the GSH concentration in astrocytes by inducing GCLc protein in them via β3-adrenoceptor stimulation.

  2. Management of childhood stuttering.

    Onslow, Mark; O'Brian, Sue

    2013-02-01

    Stuttering is a speech disorder that begins during the first years of life and is among the most prevalent of developmental disorders. It appears to be a problem with neural processing of speech involving genetics. Onset typically occurs during the first years of life, shortly after language development begins. Clinical presentation during childhood is interrupted and effortful speech production, often with rapid onset. If not corrected during early childhood, it becomes intractable and can cause psychological, social, educational and occupational problems. There is evidence from replicated clinical trials to support early intervention during the pre-school years. Meta-analysis of studies indicates that children who receive early intervention during the pre-school years are 7.7 times more likely to have resolution of their stuttering. Early intervention is recommended with a speech pathologist. Some children who begin to stutter will recover without such intervention. However, the number of such recoveries is currently not known, and it is not possible to predict which children are likely to recover naturally. Consequently, the current best practice is for speech pathologists to monitor children for signs of natural recovery for up to 1 year before beginning treatment.

    To determine the impact of insurance status and income for anaplastic astrocytoma (AA). Data were extracted from the National Cancer Data Base. Chi square test, Kaplan-Meier method, and Cox regression models were employed in SPSS 22.0 (Armonk, NY: IBM Corp.) for data analyses. 4325 patients with AA diagnosed from 2004 to 2013 were identified. 2781 (64.3%) had private insurance, 925 (21.4%) Medicare, 396 (9.2%) Medicaid, and 223 (5.2%) were uninsured. Those uninsured were more likely to be Black or Hispanic versus White or Asian (p < 0.001), have lower median income (p < 0.001), less educated (p < 0.001), and not receive adjuvant chemoradiation (p < 0.001). 1651 (38.2%) had income ≥$63,000, 1204 (27.8%) $48,000-$62,999, 889 (20.5%) $38,000-$47,999, and 581 (13.4%) had income <$38,000. Those with lower income were more likely to be Black or Hispanic versus White or Asian (p < 0.001), uninsured (p < 0.001), reside in a rural area (p < 0.001), less educated (p < 0.001), and not receive adjuvant chemoradiation (p < 0.001). Those with private insurance had significantly higher overall survival (OS) than those uninsured, on Medicaid, or on Medicare (p < 0.001). Those with income ≥$63,000 had significantly higher OS than those with lower income (p < 0.001). On multivariate analysis, age, insurance status, income, and adjuvant therapy were independent prognostic factors for OS. Being uninsured and having income <$38,000 were independent prognostic factors for worse OS in AA. Further investigations are warranted to help determine ways to ensure adequate medical care for those who may be socially disadvantaged so that outcome can be maximized for all patients regardless of socioeconomic status.

    Purpose: In a retrospective study we examined the predilection sites, the CT and MR morphology and the contrast behaviour of intracranial pilocytic astrocytoma (PA) in a large number of patients. Material and methods: The study consists of 47 patients (18 male, 29 female, mean age 10.1 years) with histologically proven PA. Results: The chief predilection site turned out to be the hypothalamic region (15/47=32%). The other regions involved were (in descending order): Brain hemispheres 8/47=17%; cerebellar vermis 7/47=15%, cerebellar hemispheres; thalamic nuclei and pontomedullar region 4/47=8.5% each; pineal gland 2/47=4%; pons, lamina tecti and optic fascicle 1/47=2% each. The PA presented 24/47=51% cysts; 7/47=15% calcifications; 2/47=4% necrosis and 1/47=2% perifocal oedema. In three cases (3/47=6%) CT and MRI showed no contrast enhancement. Conclusion: PA appear in almost all brain regions but there is a clear preference of the hypothalamic region. PA of the hypothalamic region are a special subgroup. They are often associated with neurofibromatosis 1, tend to infiltrate surrounding structures, and to dissiminate into the intracranial and spinal subarachnoid space. (orig.)

    Full Text Available Many children suffer from recurrent coughing, wheezing and chest tightness. In preschool children one third of all children have these symptoms before the age of six, but only 40% of these wheezing preschoolers will continue to have asthma. In older school-aged children the majority of the children have asthma. Quality of life is affected by asthma control. Sleep disruption and exercised induced airflow limitation have a negative impact on participation in sports and social activities, and may influence family life. The goal of asthma therapy is to achieve asthma control, but only a limited number of patients are able to reach total control. This may be due to an incorrect diagnosis, co-morbidities or poor inhalation technique, but in the majority of cases non-adherence is the main reason for therapy failures. However, partnership with the parents and the child is important in order to set individually chosen goals of therapy and may be of help to improve control. Non-pharmacological measures aim at avoiding tobacco smoke, and when a child is sensitised, to avoid allergens.

    Many children suffer from recurrent coughing, wheezing and chest tightness. In preschool children one third of all children have these symptoms before the age of six, but only 40% of these wheezing preschoolers will continue to have asthma. In older school-aged children the majority of the children have asthma. Quality of life is affected by asthma control. Sleep disruption and exercised induced airflow limitation have a negative impact on participation in sports and social activities, and may influence family life. The goal of asthma therapy is to achieve asthma control, but only a limited number of patients are able to reach total control.

    Full Text Available Background: Paraplegia of late onset in adolescents with caries of dorsal spine is considered to be due to the reactivation of infection. Internal salient at the level of acute kyphotic deformity of the dorsal spine is formed by posterior cartilaginous remains of grossly destroyed vertebral bodies. The author presents a study of eight adolescent patients with paraplegia of late onset associated with severe kyphotic deformity of dorsal spine with observations on the cause of paraplegia, the final neurological outcome following anterior decompression and its prevention. Materials and Methods: Eight adolescent patients mean age 14.4 yrs 6 males and 2 females with healed childhood caries of dorsal spine, having a mean kyphotic angle of 80° (range 60°-140° presented with paraplegia of late onset. Of these patients, two had medical research council grade 0 muscle power; four had grade 2 muscle power, and two others had grade 3 muscle power in the lower limbs and were unable to walk unaided. One patient with 140° kyphoscoliotic deformity with grade 3 muscle power had post-polio residual paralysis (PPRP in addition. All patients were subjected to thorough anterior spinal decompression through transthoracic, transpleural thoracotomy from the left side. Results: In six of the eight patients, the spine at the site of deformity being very rigid, the deformity could not be corrected and the intervertebral gap was bridged with appropriate autogenous tricortical cortico cancelluous bone graft. In one patient (case 4, the kyphotic deformity could be corrected by 50%. In one patient with 140° kyphosis and PPRP, the gap after the decompression of cord, could not be bridged with bone graft and was given a custom made, well molded plastic black shell to wear while walking and, in particular, while traveling in a vehicle. In all seven patients, bone grafts took six months for bridging the intervertebral gaps. All patients recovered to grade 4 muscle power 6

    Full Text Available The nervous breakdown of a 22-year-old, young woman was caused by severe sexual abuse in childhood, which was repressed over many years. During therapy, the patient accumulated resources to start the painful integration of these old traumas. Using holistic existential therapy in accordance with the life mission theory and the holistic process theory of healing, she finally was able to confront her old traumas and heal her existence. She seemingly recovered completely (including regaining full emotional range through holistic existential therapy, individually and in a group. The therapy took 18 months and more than 100 hours of intensive therapy. In the beginning of the therapy, the issues were her physical and mental health; in the middle of the therapy, the central issue was her purpose of life and her love life; and at the conclusion of the therapy, the issue was gender and sexuality. The strategy was to build up her strength for several months, mobilizing hidden resources and motivation for living, before the old traumas could be confronted and integrated. The therapy was based on quality of life philosophy, on the life mission theory, the theory of ego, the theory of talent, the theory of the evil side of man, the theory of human character, and the holistic process theory of healing. The clinical procedures included conversation, philosophical training, group therapeutic tools, extended use of therapeutic touch, holistic pelvic examination, and acceptance through touch was used to integrate the early traumas bound to the pelvis and scar tissue in the sexual organs. She was processed according to 10 levels of the advanced toolbox for holistic medicine and the general plan for clinical holistic psychiatry. The emotional steps she went through are well described by the scale of existential responsibility. The case story of Anna is an example of how even the most severely ill patient can recover fully with the support of holistic medical

    Epithelioid glioblastomas are one of the rarest histological variants of glioblastomas, which are not formally recognized by the World Health Organization (WHO) classification. Epithelioid glioblastomas usually occur as primary lesions, but there have been several reports of secondary epithelioid glioblastomas or epithelioid glioblastomas with pre- or co-existing lesions to date. The serine/threonine-protein kinase B-Raf (BRAF) V600E mutation has been found at a high frequency of 54% in epithelioid glioblastomas. We present a case of a 26-year-old female patient with an epithelioid glioblastoma with the BRAF V600E mutation in her right frontal lobe. In the present case, a low-grade diffuse astrocytoma component had colocalized with the epithelioid glioblastoma. The component presented prominent calcification on neuroimages as well as by histology, and low-grade diffuse astrocytoma was considered to be a precursor lesion of an epithelioid glioblastoma. However, the BRAF V600E mutation was detected only in epithelioid glioblastoma but not in low-grade diffuse astrocytoma. To the best of our knowledge, this is the first report demonstrating a discrepancy in the BRAF V600E mutation states between epithelioid glioblastoma and colocalized low-grade astrocytoma.

    In adults, the TP53 tumor suppressor gene is frequently mutated in astrocytic brain tumors which is supposed to represent an early event in their development. In juvenile pilocytic and low-grade astrocytomas, however, TP53 mutations have until now been reported as rare, which has led to the suggesti

    Full Text Available Allergic rhinitis, an immunoglobulin E mediated disease, is the most common chronic allergic childhood disease. The disease is characterized by nasal sneezing, rhinorrhea, palate and eye itchiness, and congestion and it can significantly impact children’s health. It causes uncomfortable symptoms, impairs quality of life and can predispose to the development of comorbidities such as asthma. Etiological diagnosis is based on cutaneous prick tests, which have a high sensitivity and specificity rate and which can be easily applied to young children. Treatment initially involves avoidance measures and, when necessary, pharmacotherapy or immunotherapy. Pharmacotherapy generally involves antihistamines and/or nasal corticosteroids, but leukotriene antagonists have also demonstrated effectiveness in treating allergic rhinitis symptoms. In this article, the symptoms, diagnosis and treatment of allergic rhinitis in childhood are discussed. (Journal of Current Pediatrics 2010; 8: 105-12

    JAGL differs from the Global Initiative for Asthma Guideline (GINA in that the former emphasizes long-term management of childhood asthma based on asthma severity and early diagnosis and intervention at <2 years and 2–5 years of age. However, a management method, including step-up or step-down of long-term management agents based on the status of asthma symptoms, is easy to understand and thus JAGL is suitable for routine medical treatment. JAGL also introduced treatment and management using a control test for children, recommending treatment and management aimed at complete control through avoiding exacerbation factors and appropriate use of antiinflammatory agents.

    Full Text Available Astrocytomas are common malignant intracranial tumors that comprise the majority of adult primary central nervous system tumors. MicroRNAs (miRNAs are small, non-coding RNAs (20-24 nucleotides that post-transcriptionally modulate gene expression by negatively regulating the stability or translational efficiency of their target mRNAs. In our previous studies, we found that the downregulation of miR-106a-5p in astrocytomas is associated with poor prognosis. However, its specific gene target(s and underlying functional mechanism(s in astrocytomas remain unclear. In this study, we used mRNA microarray experiments to measure global mRNA expression in the presence of increased or decreased miR-106a-5p levels. We then performed bioinformatics analysis based on multiple target prediction algorithms to obtain candidate target genes that were further validated by computational predictions, western blot analysis, quantitative real-time PCR, and the luciferase reporter assay. Fas-activated serine/threonine kinase (FASTK was identified as a direct target of miR-106a-5p. In human astrocytomas, miR-106a-5p is downregulated and negatively associated with clinical staging, whereas FASTK is upregulated and positively associated with advanced clinical stages, at both the protein and mRNA levels. Furthermore, Kaplan-Meier analysis revealed that the reduced expression of miR-106a-5p or the increased expression of FASTK is significantly associated with poor survival outcome. These results further supported the finding that FASTK is a direct target gene of miR-106a-5p. Next, we explored the function of miR-106a-5p and FASTK during astrocytoma progression. Through gain-of-function and loss-of-function studies, we demonstrated that miR-106a-5p can significantly inhibit cell proliferation and migration and can promote cell apoptosis in vitro. The knockdown of FASTK induced similar effects on astrocytoma cells as those induced by the overexpression of miR-106a-5p. These
