    FISH analysis of 41 previously karyotyped cases of MDS and AML with apparent monosomy of chromosome 20 revealed a variety of dicentric abnormalities involving chromosome 20. These usually, but not always, involved a breakpoint in the long arm of chromosome 20 and loss of the common deleted region at 20q12. Not one case of true monosomy 20 was confirmed. We found evidence for dicentric chromosome formation in 21 of 24 unbalanced translocations containing chromosome 20 and that were studied in more detail. Subsequent loss of one of the centromeres had occurred in eight of these 24 cases, and was more frequent than centromere inactivation as a means of resolving the inherent instability of a dicentric chromosome. In the three cases with dicentric chromosomes from which proximal 20q had been excised along with the 20 centromere, the excised segment was retained, and in two of these it was amplified. Proximal 20q was clearly retained in all but three cases, and present in three or more copies in 17 of 41 cases. The retention and amplification of proximal 20q provides support for the hypothesis that there is an oncogene located in this region of 20q that is activated in cases of MDS/AML with del(20q). Apparent monosomy 20 in MDS/AML should be treated as evidence of unidentified chromosome 20 abnormalities, and familiarity with the typical G-banded morphology of these derivatives can help with their identification. The reported incidence of dicentric chromosomes is clearly an under-estimate but is increasing in myeloid disorders as more cases are studied with methods allowing their detection.

    A cause of antiepileptic medication resistant seizures presenting in neonates and young infants is pyridoxine-dependent epilepsy (PDE), an organic aciduria, which is due to recessive mutations in the ALDH7A1 gene, resulting in deficiency of antiquitin. Since the discovery of molecular basis of this disorder, a few patients have been reported with a similar clinical phenotype but without evidence of antiqutin dysfunction. We report on a patient who had carried a clinical diagnosis of PDE for 7 years, but who was than shown to have normal ALDH7A1 sequencing and the absence of biomarkers characteristic of this familial epilepsy. Array comparative genomic hybridization (CGH) demonstrated a 1.5-Mb terminal deletion of the long arm of chromosome 20, which included deletion of the KCNQ2 and CHRNA4 genes, both of which have been associated with specific epilepsy syndromes. We suggest that this boy's neonatal epilepsy and neurodevelopmental disabilities are secondary to this deletion and that his clinical response to pyridoxine was coincidental. This patient's history emphasizes the utility of array CGH in the evaluation of children with epilepsy of unknown etiology.

    The recent introduction of cell-free DNA (cfDNA)-based noninvasive prenatal testing (NIPT) offers pregnant women a more accurate method than traditional serum screening methods for detecting fetal aneuploidies. Clinical trials have demonstrated the efficacy of NIPT for Down, Edwards and Patau syndromes. However NIPT approaches that take advantage of single-nucelotide polymorphism (SNP) information potentially allow the identification of triploidy, chromosomal microdeletion syndromes and other unusual genetic variants. To highlight this approach of NIPT we present a rare case of confined placental X chromosome monosomy mosaicism that was prenatally suspected with a single-nucleotide polymorphism-based noninvasive prenatal test. The results of invasive tests (amniocentesis) showed small proportion of X chromosome mosaicism (45, X[5]/46, XX[95]). After birth karyotype of the girl revealed no abnormalities (46 XX), confirming that mosaicism was limited to the placenta. These results highlight the need of patient's informed consent and thorough pretest and postest counseling to ensure that they understand the limitations and advantages of the tests and the implications of the resultss.

    Full Text Available Abstract Background Autosomal monosomies in human are generally suggested to be incompatible with life; however, there is quite a number of cytogenetic reports describing full monosomy of one chromosome 21 in live born children. Here, we report a cytogenetically similar case associated with congenital malformation including mental retardation, motor development delay, craniofacial dysmorphism and skeletal abnormalities. Results Initially, a full monosomy of chromosome 21 was suspected as only 45 chromosomes were present. However, molecular cytogenetics revealed a de novo unbalanced translocation with a der(7t(7;21. It turned out that the translocated part of chromosome 21 produced GTG-banding patterns similar to original ones of chromosome 7. The final karyotype was described as 45,XX,der(7t(7;21(q34;q22.13,-21. As a meta analysis revealed that clusters of the olfactory receptor gene family (ORF are located in these breakpoint regions, an involvement of OFR in the rearrangement formation is discussed here. Conclusion The described clinical phenotype is comparable to previously described cases with ring chromosome 21, and a number of cases with del(7(q34. Thus, at least a certain percentage, if not all full monosomy of chromosome 21 in live-borns are cases of unbalanced translocations involving chromosome 21.

    Full Text Available Abstract Monosomy 18p refers to a chromosomal disorder resulting from the deletion of all or part of the short arm of chromosome 18. The incidence is estimated to be about 1:50,000 live-born infants. In the commonest form of the disorder, the dysmorphic syndrome is very moderate and non-specific. The main clinical features are short stature, round face with short philtrum, palpebral ptosis and large ears with detached pinnae. Intellectual deficiency is mild to moderate. A small subset of patients, about 10–15 percent of cases, present with severe brain/facial malformations evocative of holoprosencephaly spectrum disorders. In two-thirds of the cases, the 18p- syndrome is due to a mere terminal deletion occurring de novo, in one-third the following are possible: a de novo translocation with loss of 18p, malsegregation of a parental translocation or inversion, or a ring chr18. Parental transmission of the 18p- syndrome has been reported. Cytogenetic analysis is necessary to make a definite diagnosis. Recurrence risk for siblings is low in de novo deletions and translocations, but is significant if a parental rearrangement is present. Deletion 18p can be detected prenatally by amniocentesis or chorionic villus sampling and cytogenetic testing. Differential diagnosis may include a wide number of syndromes with short stature and mild intellectual deficiency. In young children, deletion 18p syndrome may be vaguely evocative of either Turner syndrome or trisomy 21. No specific treatment exists but speech therapy and early educational programs may help to improve the performances of the children. Except for the patients with severe brain malformations, the life expectancy does not seem significantly reduced.

    Full Text Available We report the case of a five-month-old black male infant who had recurrent episodes of respiratory infections and also presented anemia and enlargements of the spleen, liver and lymphnodes. Hematological analysis revealed morphological abnormalities with megaloblastic dyserythropoiesis, while fetal hemoglobin assaying showed normal levels. Conventional and molecular cytogenetic analysis revealed monosomy of chromosome 7. Despite all therapeutic efforts during allogenic bone marrow transplantation, the child died due to generalized infection. The clinical and genetic distinctions between monosomy 7 syndrome and myelodysplastic disorders in childhood are discussed.

    Isochromosome of the long arm of chromosome 20 with interstitial loss of material [ider(20q)] is a rare cytogenetic abnormality reported in myelodysplastic syndrome (MDS), with neither specific morphological pattern nor clear prognostic significance. The aim of this retrospective multicentric study is to compare the peripheral blood and bone marrow morphology of MDS patients with ider(20q) (n = 13) and del(20q) (n = 21) and controls (n = 47) in order to investigate whether the ider(20q) harbors specific morphological features. The secondary objective is to compare the outcome of patients from both groups. This study performed on the largest cohort of MDS patients with ider(20q) is the first that identifies specific morphological features (hypogranulated and vacuolized neutrophils and neutrophil erythrophagocytosis) allowing the identification of this cytogenetic abnormality with high sensitivity (70%) and specificity (85.7%). Suspected ider(20q) by morphology should therefore support targeted FISH tests in case of non informative karyotype. This combined approach will allow a better estimation of the prevalence of this underdiagnozed entity. The overall survival and progression-free survival did not statistically differ in both groups. However, hypogranulated and vacuolized neutrophils were significantly associated with survival.

    Full Text Available An integrated quantitative genome data analysis was recently able to pinpoint 18 genes on human chromosome 20q that could potentially serve as novel molecular targets for cancer therapy. Researchers Antoine M Snijders and Jian-Hua Mao from Lawrence Berkeley National Laboratory’s Biological Systems and Engineering Division in Berkeley, California, United States, in their study published by the journal Advances in Modern Oncology Research (AMOR sought to compare the amounts of individual mRNAs – messenger RNAs that specify the amino acid sequence of the protein products of gene expression – in cancerous human tissues with corresponding normal tissues. The duo conducted a meta-analysis of genes on chromosome 20q that are found to be consistently upregulated across different human tumor types, while collecting gene transcript data of normal and tumor tissues across 11 different tumor types including brain, breast, colon, gastric, head and neck, liver, lung, ovarian, cervix, pancreas, and prostate cancers. “We calculated the differential expression of all 301 genes present on chromosome 20q for which gene transcript data was available. We then filtered for genes that were upregulated in tumors by at least 1.5 fold (p < 0.05 in seven or more tumor types,” they said. The resulting analysis identified 18 genes – some such as AURKA, UBE2C, TPX2, FAM83D, ZNF217, SALL4 and MMP9 have been previously known to potentially cause cancer. The 18-gene signature is revealed by the study to have robustly elevated levels across human cancers. “We observed significant association of our signature with disease-free survival in all 18 independent data… These data indicated that our signature is broadly predictive for disease-free survival, independent of tumor type,” the researchers said. In certain cases, Snijders and Mao found that increased gene expression was associated with better prognosis. “For example, the increased expressions of MMP9 and

    Monosomy of chromosome 17 may affect the assessment of HER2 amplification. Notably, the prevalence ranges from 1% up to 49% due to lack of consensus in recognition. We sought to investigate the impact of monosomy of chromosome 17 to interpretation of HER2 gene status. 201 breast carcinoma were reviewed for HER2 gene amplification and chromosome 17 status. FISH analysis was performed by using double probes (LSI/CEP). Absolute gene copy number was also scored per each probe. HER2 FISH test was repeated on serial tissue sections, ranging in thickness from 3 to 20 µm. Ratio was scored and subsequently corrected by monosomy after gold control test using the aCGH method to overcome false interpretation due to artefactual nuclear truncation. HER2 immunotests was performed on all cases. 26/201 cases were amplified (13%). Single signals per CEP17 were revealed in 7/201 (3.5%) cases. Five out of 7 cases appeared monosomic with aCGH (overall, 5/201, 2.5%) and evidenced single signals in >60% of nuclei after second-look on FISH when matching both techniques. Among 5, one case showed amplification with a pattern 7/1 (HER2/CEP17>2) of copies (3+ at immunotest); three cases revealed single signals per both probes (LSI/CEP=1) and one case revealed a 3:1 ratio; all last 4 cases showed 0/1+ immunoscore. We concluded that: 1) monosomy of chromosome 17 may be observed in 2.5% of breast carcinoma; 2) monosomy of chromosome 17 due to biological reasons rather than nuclear truncation was observed when using the cut-off of 60% of nuclei harboring single signals; 3) the skewing of the ratio due to single centromeric 17 probe may lead to false positive evaluation; 4) breast carcinomas showing a 3:1 ratio (HER2/CEP17) usually show negative 0/1+ immunoscore and <6 gene copy number at FISH.

    We describe a 13-year-old boy with developmental delay and proximal muscle weakness who has monosomy 20 mosaicism in blood and skin cells. Because of asymmetric features (difference in foot size, slightly asymmetric intergluteal cleft), we performed extensive cytogenetic studies in peripheral blood and skin. In cultured and uncultured blood lymphocytes, we found 0.9 and 6.5% of cells with monosomy 20, respectively. In addition, 3.3% of uncultured skin fibroblasts and 1.5% of buccal mucosa cells had monosomy 20. This is the fifth patient published with this chromosomal condition. These patients show variable clinical features, ranging from normal to delayed motor and speech development. There is no apparent relation between the percentage of monosomic cells as studied in blood and the severity of the phenotype. This could be due to different degrees of mosaicism in the other tissues and organs, which may vary considerably from patient to patient. The degree of monosomy 20 mosaicism in blood is in most patients below the detection limit of microarray technology. Therefore, this work illustrates the necessity of detailed cytogenetic investigation of multiple cell types in developmentally retarded patients with normal microarray results, especially when there are subtle physical indications of chromosomal mosaicism.

  13. Amplification of the 20q chromosomal arm occurs early in tumorigenic transformation and may initiate cancer.

    Full Text Available Duplication of chromosomal arm 20q occurs in prostate, cervical, colon, gastric, bladder, melanoma, pancreas and breast cancer, suggesting that 20q amplification may play a causal role in tumorigenesis. According to an alternative view, chromosomal imbalance is mainly a common side effect of cancer progression. To test whether a specific genomic aberration might serve as a cancer initiating event, we established an in vitro system that models the evolutionary process of early stages of prostate tumor formation; normal prostate cells were immortalized by the over-expression of human telomerase catalytic subunit hTERT, and cultured for 650 days till several transformation hallmarks were observed. Gene expression patterns were measured and chromosomal aberrations were monitored by spectral karyotype analysis at different times. Several chromosomal aberrations, in particular duplication of chromosomal arm 20q, occurred early in the process and were fixed in the cell populations, while other aberrations became extinct shortly after their appearance. A wide range of bioinformatic tools, applied to our data and to data from several cancer databases, revealed that spontaneous 20q amplification can promote cancer initiation. Our computational model suggests that 20q amplification induced deregulation of several specific cancer-related pathways including the MAPK pathway, the p53 pathway and Polycomb group factors. In addition, activation of Myc, AML, B-Catenin and the ETS family transcription factors was identified as an important step in cancer development driven by 20q amplification. Finally we identified 13 "cancer initiating genes", located on 20q13, which were significantly over-expressed in many tumors, with expression levels correlated with tumor grade and outcome suggesting that these genes induce the malignant process upon 20q amplification.

    Previous genomewide association studies (GWAS) identified a region near MAFB at chr20q12 associated with non-syndromic orofacial clefts (NSOC) susceptibility. However, whether other SNPs in this area could independently contribute to non-syndromic orofacial clefts in Chinese populations remained obscure. We selected 24 SNPs based on a haplotype-tagging SNP strategy and evaluated their associations with risk of non-syndromic orofacial clefts in a large-scale two-stage case-control study with 1278 cases and 1295 controls. Genotyping was performed with Sequenom and TaqMan assay. Associations between the SNPs and risk of non-syndromic orofacial clefts were estimated from unconditional logistic regression analyses. Overall, six SNPs were found to be the susceptible factors of non-syndromic orofacial clefts. The most significant and independent SNP was rs6129653 (additive model of P value = 1.4E-06). In subgroup analysis, its significant associations with cleft lip only (CLO) and cleft lip and palate (CLP) were observed. Furthermore, in silico bioinformatics analysis indicated that rs6129653 was located in the transcriptionally active region and associated with MAFB expression in human brain tissues. Rs6129653 was an independent locus of non-syndromic orofacial clefts among Chinese populations possibly due to its potential of distal transcriptional regulation of MAFB expression. © 2016 John Wiley & Sons A/S.

    2005-01-01

    Full Text Available Background: Gain of the q arm of chromosome 20 in human colorectal cancer has been associated with poorer survival time and has been reported to increase in frequency from adenomas to metastasis. The increasing frequency of chromosome 20q amplification during colorectal cancer progression and the presence of this amplification in carcinomas of other tissue origin has lead us to hypothesize that 20q11-13 harbors one or more genes which, when over expressed promote tumor invasion and metastasis. Aims: Generate genomic and expression profiles of the 20q amplicon in human cancer cell lines in order to identify genes with increased copy number and expression. Materials and Methods: Utilizing genomic sequencing clones and amplification mapping data from our lab and other previous studies, BAC/ PAC tiling paths spanning the 20q amplicon and genomic microarrays were generated. Array-CGH on the custom array with human cancer cell line DNAs was performed to generate genomic profiles of the amplicon. Expression array analysis with RNA from these cell lines using commercial oligo microarrays generated expression profiles of the amplicon. The data were then combined in order to identify genes with increased copy number and expression. Results: Over expressed genes in regions of increased copy number were identified and a list of potential novel genetic tumor markers was assembled based on biological functions of these genes Conclusions: Performing high-resolution genomic microarray profiling in conjunction with expression analysis is an effective approach to identify potential tumor markers.

    Bello, Sabina; Rodríguez-Moreno, Antonio

    The Monosomy 1p36 deletion syndrome is part of the group of diseases known as Rare Diseases. The objective of the present work is to review the characteristics of Monosomy 1p36 deletion syndrome. The monosomy 1p36 deletion syndrome phenotype includes: dysmorphic craniofacial features; large anterior fontanelle, unibrow, deep-set eyes, epicanthus, wide nasal root/bridge, mandible hypoplasia, abnormal location of the pinna, philtrum and pointed chin; neurological alterations: seizures and hydrocephalus (in some cases). Cerebral malformations: ventricular hypertrophy, increased subarachnoid space, morphological alterations of corpus callosum, cortical atrophy, delays in myelinisation, periventricular leukomalacia and periventricular heterotopia. These alterations produce intellectual disability and delays in motor growth, communication skills, language, social and adaptive behaviour. It is Hearing and vision impairments are also observed in subjects with this syndrome, as well as alterations of cardiac, endocrine and urinary systems and alterations at skin and skeletal level. Approximately 100 cases have been documented since 1981. This rare disease is the most common subtelomeric-micro-deletion syndrome. In situ hybridization with fluorescence (FISH) and array-comparative genomic hybridization (CGH-array) are at present the two best diagnostic techniques. There is currently no effective medical treatment for this disease. Copyright © 2016 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U. All rights reserved.

    By analyzing five human embryonic stem (hES) cell lines over long-term culture, we identified a recurrent genomic instability in the human genome. An amplification of 2.5-4.6 Mb at 20q11.21, encompassing approximately 23 genes in common, was detected in four cell lines of different origins. This amplification, which has been associated with oncogenic transformation, may provide a selective advantage to hES cells in culture.

    Interstitial duplication within the long arm of chromosome 20 is an uncommon chromosome structural abnormality. We report here the clinical and molecular characterization associated with pure 20q13.2 duplication in three unrelated patients. The most frequent clinical features were developmental delay, facial dysmorphism, cardiac malformation and skeletal anomalies. All DNA gains occurred de novo, ranging from 1.1 Mb to 11.5 Mb. Compared with previously reported conventional cytogenetic analyses, oligonucleotides array CGH allowed us to refine breakpoints and determine the genes of interest in the region. Involvement of SALL4 in cardiac malformations and NFATC2 gene disruption in both cardiac and skeletal anomalies are discussed.

    We report on a family with an abnormality of 10p. The propositus has monosomy for the distal region of 10p and severe psychomotor delay, growth failure, congenital heart defect, multicystic kidney, grade V vesicoureteric reflux, and neurosensory hearing loss. The mother and the elder brother of the propositus carry a balanced reciprocal translocation (5q;10p)(q35.3;p12.3). A retarded and epileptic maternal aunt was found to have dup(10p). Study of the family history led to the successful obstetric management of a subsequent twin pregnancy in which an affected fetus with dup(10p) was identified and selectively terminated, while the other normal twin was delivered at term without problems. 25 refs., 4 figs., 1 tab.

    Full Text Available The spinal muscular atrophies (SMA or hereditary motor neuronopathies result from the continuous degeneration and death of spinal cord lower motor neurons, leading to progressive muscular weakness and atrophy. We describe a large Brazilian family exhibiting an extremely rare, late-onset, dominant, proximal, and progressive SMA accompanied by very unusual manifestations, such as an abnormal sweating pattern, and gastrointestinal and sexual dysfunctions, suggesting concomitant involvement of the autonomic nervous system. We propose a new disease category for this disorder, `hereditary motor and autonomic neuronopathy', and attribute the term, `survival of motor and autonomic neurons 1' (SMAN1 to the respective locus that was mapped to a 14.5 cM region on chromosome 20q13.2-13.3 by genetic linkage analysis and haplotype studies using microsatellite polymorphic markers. This locus lies between markers D20S120 and D20S173 showing a maximum LOD score of 4.6 at D20S171, defining a region with 33 known genes, including several potential candidates. Identifying the SMAN1 gene should not only improve our understanding of the molecular mechanisms underlying lower motor neuron diseases but also help to clarify the relationship between motor and autonomic neurons.

    We report on a male Japanese patient with hairy cell leukemia (HCL). A cytogenetic study with lipopolysaccharide stimuli showed a novel translocation (11;20)(q13;q11) in 10% of the analyzed cells. Northern blot analysis and RT-PCR analysis for cyclin D1 revealed the overexpression of cyclin D1, although the southern blot analysis of PRAD1 gene showed no rearrangement. In this particular case, the t(11;20)(q13;q11) might play some role in the oncogenesis of HCL and the overexpression of cyclin D1.

    Full Text Available We report a case of a neonate who was shown with routine chromosome analysis on peripheral blood lymphocytes to have full monosomy 21. Further investigation on fibroblast cells using conventional chromosome and FISH analysis revealed two additional mosaic cell lines; one is containing a ring chromosome 21 and the other a double ring chromosome 21. In addition, chromosome microarray analysis (CMA on fibroblasts showed a mosaic duplication of chromosome region 21q11.2q22.13 with approximately 45% of cells showing three copies of the proximal long arm segment, consistent with the presence of a mosaic ring chromosome 21 with ring instability. The CMA also showed complete monosomy for an 8.8 Mb terminal segment (21q22.13q22.3. Whilst this patient had a provisional clinical diagnosis of trisomy 21, the patient also had phenotypic features consistent with monosomy 21, such as prominent epicanthic folds, broad nasal bridge, anteverted nares, simple ears, and bilateral overlapping fifth fingers, features which can also be present in individuals with Down syndrome. The patient died at 4.5 months of age. This case highlights the need for additional studies using multiple tissue types and molecular testing methodologies in patients provisionally diagnosed with monosomy 21, in particular if detected in the neonatal period.

    Full Text Available DNA methylation is a key epigenetic mechanism responsible for gene regulation, chromatin remodeling, and genome stability, playing a fundamental role during embryonic development. The aim of this study was to determine if these epigenetic marks are associated with chromosomal aneuploidy in human blastocysts. Surplus, cryopreserved blastocysts that were donated to research with IRB consent were chosen with varying chromosomal aneuploidies and respective implantation potential: monosomies and trisomies 7, 11, 15, 21, and 22. DNA methylation analysis was performed using the Illumina Infinium HumanMethylation450 BeadChip (~485,000 CpG sites. The methylation profiles of these human blastocysts were found to be similar across all samples, independent of chromosome constitution; however, more detailed examination identified significant hypomethylation in the chromosome involved in the monosomy. Real-time PCR was also performed to determine if downstream messenger RNA (mRNA was affected for genes on the monosomy chromosome. Gene dysregulation was observed for monosomy blastocysts within significant regions of hypo-methylation (AVEN, CYFIP1, FAM189A1, MYO9A, ADM2, PACSIN2, PARVB, and PIWIL3 (P < 0.05. Additional analysis was performed to examine the gene expression profiles of associated methylation regulators including: DNA methyltransferases (DNMT1, DNMT3A, DNMT3B, DNMT3L, chromatin modifying regulators (CSNK1E, KDM1, PRKCA, and a post-translational modifier (PRMT5. Decreased RNA transcription was confirmed for each DNMT, and the regulators that impact DNMT activity, for only monosomy blastocysts (P < 0.05. In summary, monosomy blastocysts displayed hypomethylation for the chromosome involved in the error, as well as transcription alterations of associated developmental genes. Together, these modifications may be contributing to genetic instability and therefore be responsible for the limited implantation potential observed for full monosomy

    Purpose: To report the ocular response of choroidal melanoma with monosomy 3 vs. disomy 3 after {sup 125}I brachytherapy. Methods and Materials: We evaluated patients with ciliochoroidal melanoma managed with fine needle aspiration biopsy immediately before plaque application for {sup 125}I brachytherapy between January 1, 2005 and December 31, 2008. Patients with (1) cytopathologic diagnosis of melanoma, (2) melanoma chromosome 3 status identified by fluorescence in situ hybridization, and (3) 6 or more months of follow-up after brachytherapy were sorted by monosomy 3 vs. disomy 3 and compared by Kruskal-Wallis test. Results: Among 40 ciliochoroidal melanomas (40 patients), 15 had monosomy 3 and 25 had disomy 3. Monosomy 3 melanomas had a median greatest basal diameter of 12.00 mm and a median tumor thickness of 6.69 mm before brachytherapy; at a median of 1.75 years after brachytherapy, median thickness was 3.10 mm. Median percentage decrease in tumor thickness was 48.3%. Disomy 3 melanomas had a median greatest basal diameter of 10.00 mm and median tumor thickness of 3.19 mm before brachytherapy; at a median of 2.00 years after brachytherapy, median tumor thickness was 2.37 mm. The median percentage decrease in tumor thickness was 22.7%. Monosomy 3 melanomas were statistically greater in size than disomy 3 melanomas (p < 0.001) and showed a greater decrease in tumor thickness after brachytherapy (p = 0.006). Conclusion: In this study, ciliochoroidal melanomas with monosomy 3 were significantly greater in size than disomy 3 melanoma and showed a significantly greater decrease in thickness at a median of 1.75 years after brachytherapy. The greater decrease in monosomy 3 melanoma thickness after brachytherapy is consistent with other malignancies in which more aggressive pathology has been shown to be associated with a greater initial response to radiotherapy.

    infrequency of ANXA7 mutation (≈6% of tumors) indicates its role as a haploinsufficiency gene. ANXA7 mRNA transcript expression, dichotomized at the median, associates with patient survival in 191 glioblastomas (log-rank P=.008; hazard ratio [HR], 0.667; 95% confidence interval [CI], 0.493–0.902; 46.9 vs 74.8 deaths/100 person-years for high vs low ANXA7 mRNA expression) and with a separate group of 180 high-grade gliomas (log-rank P=.00003; HR, 0.476; 95% CI, 0.333–0.680; 21.8 vs 50.0 deaths/100 person-years for high vs low ANXA7 mRNA expression). Deletion of the ANXA7 gene associates with poor patient survival in 189 glioblastomas (log-rank P=.042; HR, 0.686; 95% CI, 0.476–0.989; 54.0 vs 80.1 deaths/100 person-years for wild-type ANXA7 vs ANXA7 deletion). Conclusion Haploinsufficiency of the tumor suppressor ANXA7 due to monosomy of chromosome 10 provides a clinically relevant mechanism to augment EGFR signaling in glioblastomas beyond that resulting from amplification of the EGFR gene.

    Full Text Available Myelodysplastic syndrome (MDS is a clonal bone marrow disorder characterized by ineffective hematopoiesis. It is characterized by peripheral blood cytopenia and significant risk of progression to acute myeloid leukemia result. Deletion of the long arm of chromosome 20 (20q deletion is present in 3–7% of patients with MDS. Lenalidomide is an immunomodulatory agent with antiangiogenic activity. It is FDA approved for the treatment of anemia in patients with low or int-1 risk MDS with chromosome 5q deletion with or without additional cytogenetic abnormalities. Study of lenalidomide in patients with MDS without 5q deletion but other karyotypic abnormalities demonstrated meaningful activity in transfusion dependent patients; however, response of patients with isolated 20q deletion to lenalidomide is not known. We are reporting a patient with 20q deletion MDS treated with lenalidomide after he failed to respond to azacytidine; to our knowledge this is the first report of a patient with isolated 20q deletion treated with lenalidomide.

    To assess the distribution of the parental origin of the retained X chromosome in monosomy X, either in miscarriages or in ongoing pregnancies. The parental origin of the X chromosome was determined in monosomy X pregnancies, either miscarriages or ongoing pregnancies. Microsatellite marker patterns were compared between maternal and fetal samples by quantitative fluorescence polymerase chain reaction. Distributions of maternally and paternally derived X chromosome were assessed in miscarriages and in ongoing pregnancies using two-tailed Fisher exact test. Forty monosomy X pregnancies were included in the study: 26 miscarried at 5-16 weeks, and 14 ongoing pregnancies were diagnosed at 11-20 weeks. The retained X chromosome was maternally derived in 67% of the cases. In miscarriages, maternal and paternal X chromosome were retained in a similar proportion (54% [95% CI: 35-73%] vs. 46% [95% CI: 27-65%]), while in ongoing pregnancies, the maternal rate was 13 times higher (93% [95% CI: 79-100%)] vs. 7% [95% CI: 0-20%]). The retained X chromosome in individuals with monosomy X should theoretically be maternally derived in 2/3 of the cases. Our study suggests a preferential early miscarriage in pregnancies with a retained paternally derived X chromosome. This may explain the observation that 75-90% of individuals with monosomy X retain the maternal X chromosome. © 2017 S. Karger AG, Basel.

    Pseudohypoparathyroidism type Ib (PHP1B) is caused by proximal tubular resistance to parathyroid hormone that occurs in most cases in the absence of Albright's Hereditary Osteodystrophy (AHO). Familial forms of PHP1B are caused by maternally inherited microdeletions within STX16, the gene encoding syntaxin 16, or within GNAS, a complex genetic locus on chromosome 20q13.3 encoding Gsα and several splice variants thereof. These deletions lead either to a loss-of-methylation affecting GNAS exon A/B alone or to epigenetic changes involving multiple differentially methylated regions (DMRs) within GNAS. Broad GNAS methylation abnormalities are also observed in most sporadic PHP1B (sporPHP1B) cases. However, with the exception of paternal uniparental disomy involving chromosome 20q (patUPD20q), the molecular mechanism leading to this disease variant remains unknown. We now investigated 23 Japanese sporPHP1B cases, who presented with hypocalcemia, hyperphosphatemia, elevated PTH levels, and occasionally with TSH elevations and mild AHO features. Age at diagnosis was 10.6 ± 1.45 years. Calcium, phosphate, and PTH were 6.3 ± 0.23 mg/dL, 7.7 ± 0.33 mg/dL, and 305 ± 34.5 pg/mL, respectively, i.e. laboratory findings that are indistinguishable from those previously observed for Caucasian sporPHP1B cases. All investigated patients showed broad GNAS methylation changes. Eleven individuals were homozygous for SNPs within exon NESP and a pentanucleotide repeat in exon A/B. Two of these patients furthermore revealed homozygosity for numerous microsatellite markers on chromosome 20q raising the possibility of patUPD20q, which was confirmed through the analysis of parental DNA. Based on this and our previous reports, paternal duplication of the chromosomal region comprising the GNAS locus appears to be a fairly common cause of sporPHP1B that is likely to occur with equal frequency in Caucasians and Asians.

    Full Text Available To screen for monosomy X in spontaneous fetal losses we explored a simple molecular strategy based on loss of heterozygosity at highly polymorphic X-linked loci. We developed a multiplex fluorescent procedure that allows the simultaneous amplification of five dinucleotide repeat polymorphisms in a large low-recombination region in the long arm of the X chromosome. Analysis was performed by computer-assisted laser densitometry. We did not find any instances of homozygosity at all five loci in 30 normal females tested, nor among 37 women whose typing data were retrieved from the Fondation Jean Dausset - CEPH genotype database. In addition, all cases of monosomy X previously diagnosed by conventional cytogenetics presented the anticipated loss of heterozygosity at all loci. We studied 19 spontaneously aborted female fetuses and we found four samples homozygous for the five loci (21%, in good agreement with the expected rate of monosomy X in first trimester spontaneous abortions. We conclude that the loci have high diversity and high efficiency in PCR-amplification and that our multiplex procedure constitutes a simple and useful molecular screening test for monosomy X in abortions and stillbirths.

    Deletion of 20q is a common finding in myeloid disorders but it is also observed in plasma cell myeloma (PCM). As a del(20q) in a patient receiving treatment for myeloma may indicate therapy-related myelodysplastic syndrome (t-MDS), it is important to differentiate chromosome abnormalities associated with myeloma from those reflecting t-MDS. We performed fluorescence in situ hybridization (FISH) using a 20q12 probe (D20S108) in conjunction with cytoplasmic immunoglobulin (cIg) staining in 20 PCM cases with a del(20q) in order to confirm the cell type involved. Of the nine cases studied with a clone showing a del(20q) as the sole abnormality, 8 of 9 demonstrated loss of the D20S108 signals in non-plasma cells only and 5 of 9 had either a confirmed myeloid malignancy in addition to PCM or showed evidence of dysplastic changes in the marrow; however, of the 11 patients with a del(20q) within a complex PCM karyotype, 4 of 11 showed loss of the D20S108 signals in plasma cells only and 7 of 11 showed no significant loss in either plasma cells or non-plasma cells. Therefore, our results indicate that a del(20q) as the sole abnormality in PCM is present in non-plasma cells and, therefore, suggests the presence of an associated myeloid malignancy.

    Full Text Available Background/Objectives. To identify copy number variants (CNVs which are associated with body mass index (BMI. Subjects/Methods. CNVs were identified using array comparative genomic hybridization (aCGH on members of pedigrees ascertained through severely obese (BMI ≥ 35 kg/m2 sib pairs (86 pedigrees and thin (BMI ≤ 23 kg/m2 probands (3 pedigrees. Association was inferred through pleiotropy of BMI with CNV log⁡2 intensity ratio. Results. A 77-kilobase CNV on chromosome 20q13.3, confirmed by real-time qPCR, exhibited deletions in the obese subjects and duplications in the thin subjects (P=2.2×10-6. Further support for the presence of a deletion derived from inference by likelihood analysis of null alleles for SNPs residing in the region. Conclusions. One or more of 7 genes residing in a chromosome 20q13.3 CNV region appears to influence BMI. The strongest candidate is ARFRP1, which affects glucose metabolism in mice.

  15. Accurate, Fast and Cost-Effective Diagnostic Test for Monosomy 1p36 Using Real-Time Quantitative PCR

    Full Text Available Monosomy 1p36 is considered the most common subtelomeric deletion syndrome in humans and it accounts for 0.5–0.7% of all the cases of idiopathic intellectual disability. The molecular diagnosis is often made by microarray-based comparative genomic hybridization (aCGH, which has the drawback of being a high-cost technique. However, patients with classic monosomy 1p36 share some typical clinical characteristics that, together with its common prevalence, justify the development of a less expensive, targeted diagnostic method. In this study, we developed a simple, rapid, and inexpensive real-time quantitative PCR (qPCR assay for targeted diagnosis of monosomy 1p36, easily accessible for low-budget laboratories in developing countries. For this, we have chosen two target genes which are deleted in the majority of patients with monosomy 1p36: PRKCZ and SKI. In total, 39 patients previously diagnosed with monosomy 1p36 by aCGH, fluorescent in situ hybridization (FISH, and/or multiplex ligation-dependent probe amplification (MLPA all tested positive on our qPCR assay. By simultaneously using these two genes we have been able to detect 1p36 deletions with 100% sensitivity and 100% specificity. We conclude that qPCR of PRKCZ and SKI is a fast and accurate diagnostic test for monosomy 1p36, costing less than 10 US dollars in reagent costs.

    A 21-year-old woman with a short stature presented with primary amenorrhoea and a 45X karyotype, and comparative genomic hybridization revealed 1p36 deletion and abnormal genes in multiple chromosomes to support the diagnosis of Turner syndrome and monosomy 1p36 deletion syndrome. The main clinical features of this condition include microsomia, poor sexual development, menoschesis, gigantorectum, absence of internal genitalia, sometimes with thyropenia and low intelligence. This disease can be easily diagnosed for its heterogeneous clinical manifestations.

    Uveal melanoma is a rare intraocular tumor with heterogeneous biological behavior, and additional noninvasive markers that may predict outcome are needed. Diffusion- and perfusion-weighted imaging may prove useful but have previously been limited in their ability to evaluate ocular tumors. Our purpose was to show the feasibility and potential value of a multiparametric (mp-) MRI protocol employing state of the art diffusion- and perfusion-weighted imaging techniques. Sixteen patients with uveal melanoma were imaged with mp-MRI. Multishot readout-segmented echoplanar diffusion-weighted imaging, quantitative dynamic contrast-enhanced (DCE) MR perfusion imaging, and anatomic sequences were obtained. Regions of interest (ROIs) were drawn around tumors for calculation of apparent diffusion coefficient (ADC) and perfusion metrics (K{sup trans}, v{sub e}, k{sub ep}, and v{sub p}). A generalized linear fit model was used to compare various MRI values with the American Joint Commission on Cancer (AJCC) tumor group and monosomy 3 status with significance set at P < 0.05. mp-MRI was performed successfully in all cases. MRI tumor height (mean [standard deviation]) was 6.5 mm (3.0). ROI volume was 278 mm{sup 3} (222). ADC was 1.07 (0.27) x 10-3 mm{sup 2}/s. DCE metrics were K{sup trans} 0.085/min (0.063), v{sub e} 0.060 (0.052), k{sub ep} 1.20/min (0.32), and v{sub p} 1.48 % (0.82). Patients with >33 % monosomy 3 had higher K{sup trans} and higher v{sub e} values than those with disomy 3 or ≤33 % monosomy (P < 0.01). There were no significant differences between ADC (P = 0.07), k{sub ep} (P = 0.37), and v{sub p} with respect to monosomy 3. mp-MRI for ocular tumor imaging using multishot EPI DWI and quantitative DCE perfusion is technically feasible. mp-MRI may help predict monosomy 3 in uveal melanoma.

    Central diabetes insipidus (DI) is well-documented as a presenting feature of myelodysplastic syndrome and acute myeloid leukemia in adults. However, DI is unusual in pediatric patients with myeloid malignancies. We report here this rare complication in a child with neurofibromatosis type 1 who developed juvenile myelomonocytic leukemia and monosomy 7. Our case and previously reported cases of DI arising as a complication in myeloid malignancies demonstrate a close association with deletion of chromosome 7. The clinical characteristics and outcomes of these uncommon cases in children are reviewed and discussed.

    Full Text Available Partial deletion of the long arm of chromosome 13 is a rare chromosomal aberration which is related to mental retardation, growth restriction and various congenital malformations. Central nervous system, cardiac, genitourinary, skeletal malformations and craniofacial dysmorphism can be observed. Prenatal diagnosis is possible by karyotyping and early genetic sonogram. Prenatal diagnosis can be difficult in cases that are not accompanied by major malformations but mental retardation and developmental delay in the forefront. In this report we aimed to present a case diagnosed 13-q syndrome prenatally as a result of karyotyping done due to multiple abnormal ultrasound findings in 14 weeks of pregnancy.

  1. From DNA Copy Number to Gene Expression: Local aberrations, Trisomies and Monosomies

    Science.gov (United States)

    Shay, Tal

    The goal of my PhD research was to study the effect of DNA copy number changes on gene expression. DNA copy number aberrations may be local, encompassing several genes, or on the level of an entire chromosome, such as trisomy and monosomy. The main dataset I studied was of Glioblastoma, obtained in the framework of a collaboration, but I worked also with public datasets of cancer and Down's Syndrome. The molecular basis of expression changes in Glioblastoma. Glioblastoma is the most common and aggressive type of primary brain tumors in adults. In collaboration with Prof. Hegi (CHUV, Switzerland), we analyzed a rich Glioblastoma dataset including clinical information, DNA copy number (array CGH) and expression profiles. We explored the correlation between DNA copy number and gene expression at the level of chromosomal arms and local genomic aberrations. We detected known amplification and over expression of oncogenes, as well as deletion and down-regulation of tumor suppressor genes. We exploited that information to map alterations of pathways that are known to be disrupted in Glioblastoma, and tried to characterize samples that have no known alteration in any of the studied pathways. Identifying local DNA aberrations of biological significance. Many types of tumors exhibit chromosomal losses or gains and local amplifications and deletions. A region that is aberrant in many tumors, or whose copy number change is stronger, is more likely to be clinically relevant, and not just a by-product of genetic instability. We developed a novel method that defines and prioritizes aberrations by formalizing these intuitions. The method scores each aberration by the fraction of patients harboring it, its length and its amplitude, and assesses the significance of the score by comparing it to a null distribution obtained by permutations. This approach detects genetic locations that are significantly aberrant, generating a 'genomic aberration profile' for each sample. The 'genomic

    Full Text Available Monosomy 7 arises as a recurrent chromosome aberration in donor cell leukemia after hematopoietic stem cell transplantation. We report a new case of donor cell leukemia with monosomy 7 following HLA-identical allogenic bone marrow transplantation for severe aplastic anemia (SAA. The male patient received a bone marrow graft from his sister, and monosomy 7 was detected only in the XX donor cells, 34 months after transplantation. The patient's bone marrow microenvironment may have played a role in the leukemic transformation of the donor hematopoietic cells.

    Prenatal diagnosis was performed in a woman whose previous pregnancy resulted in a girl with probable Down syndrome who died soon after delivery.

Despite partial monosomy for the proximal segment of 22 and trisomy for proximal 21, the fetus did not have gross external abnormalities, but several internal malformations were found. To our knowledge, this is the first time that this unbalanced karyotype has been described. Images PMID:6460105

    This study was aimed to investigate the distribution of abnormal clone in marrow cell lineages and apoptosis cells in myelodysplastic syndrome (MDS) with deletion of chromosome 20q. Monoclonal antibodies recognizing myeloid precursors (CD15), erythroid precursors (GPA), T cells (CD3(+)CD56(-)CD16(-)), B cells (CD19), NK cells (CD3(-)CD56(+)CD16(+)) were used to sort bone marrow cells in a MDS patient with del (20q) by fluorescence activated cell sorting (FACS). Annexin V-FITC and PI were used to sort bone marrow Annexin V(+)PI(-) and Annexin V(-)PI(-) cells by FACS. The sorted positive cells were detected by interphase dual-color fluorescence in situ hybridization (D-FISH) using a LSI D20S108 probe (Spectrum Orange) and a Telvysion TM 20p probe (Spectrum Green). FACS and FISH analysis were also performed on the samples from 4 cases with normal karyotype. The results showed that the proportions of MDS clone in the myeloid and erythroid precursors were 70.50% and 93.33% respectively, in the RAEB-1 patient with del (20q) and were obviously higher than that in control group (5.39% and 6.17%). The proportions of abnormal clone in T, B and NK cells were 3.23%, 4.32% and 5.77% respectively and were less than that in control group (5.76%, 4.85%, 6.36%). The percentage of apoptotic cells in the bone marrow nucleated cells was 16.09%. The proportions of MDS clone in Annexin V(+)PI(-) and Annexin V(-)PI(-) cells were 32.48% and 70.11%, respectively. It is concluded that most myeloid and erythroid precursors are originated from the abnormal clone in MDS with del (20q). A little part of apoptotic cells are derived from the abnormal clone.

    Recently, Lopez-Pajares et al. (1993) reported identification of a translocation between the short arm of a chromosome 5 and the long arm of a chromosome 21 in a patient who was thought to be monosomy 21. This study is the first application of a chromosome 21 painting probe, pBS-21, and fluorescent in situ chromosome hybridization (FISH) to revise an earlier diagnosis of monosomy 21. We have now restudied skin fibroblast cultures, GM00137B, that are still available from another patient previously described as {open_quotes}presumptive monosomy 21{close_quotes} and have found that this case also has a translocation involving chromosomes 21 and 4. The authors urge that all previous cases of what appeared to be monosomy 21 should be re-examined with FISH to confirm or revise the original diagnosis so that genetic counseling of the family may be updated. 3 refs., 3 figs.

    We report a new-born girl with partial trisomy of 4q28-qter and partial monosomy of 9p24-9ter. Our patient has choanal atresia, hypertelorism, wide nasal bridge, high arched palate, discrete nipples, heart defects, myoclonic seizures and various dysmorphic findings. Standard chromosomal analysis with G-banding with Trypsin-Giemsa revealed 46,XX,der(9)t(4;9)(q28;p24) resulting from the mother's t(4,9) (q28;p24) karyotype. Deletions of the terminal part of 9p and partial trisomy of chromosome 4q are rare chromosomal alterations. To our knowledge, this is the first report of choanal atresia in a patient with a partial trisomy of 4q28-qter and partial monosomy 9p24-9ter combination, which were detected by integrated cytogenetic and genomic analysis.

    Full Text Available Partial monosomy 21 (PM21 is a rare chromosomal abnormality that is characterized by the loss of a variable segment along human chromosome 21 (Hsa21. The clinical phenotypes of this loss are heterogeneous and range from mild alterations to lethal consequences, depending on the affected region of Hsa21. The most common features include intellectual disabilities, craniofacial dysmorphology, short stature, and muscular and cardiac defects. As a complement to human genetic approaches, our team has developed new monosomic mouse models that carry deletions on Hsa21 syntenic regions in order to identify the dosage-sensitive genes that are responsible for the symptoms. We focus here on the Ms5Yah mouse model, in which a 7.7-Mb region has been deleted from the App to Runx1 genes. Ms5Yah mice display high postnatal lethality, with a few surviving individuals showing growth retardation, motor coordination deficits, and spatial learning and memory impairments. Further studies confirmed a gene dosage effect in the Ms5Yah hippocampus, and pinpointed disruptions of pathways related to cell adhesion (involving App, Cntnap5b, Lgals3bp, Mag, Mcam, Npnt, Pcdhb2, Pcdhb3, Pcdhb4, Pcdhb6, Pcdhb7, Pcdhb8, Pcdhb16 and Vwf. Our PM21 mouse model is the first to display morphological abnormalities and behavioural phenotypes similar to those found in affected humans, and it therefore demonstrates the major contribution that the App-Runx1 region has in the pathophysiology of PM21.

    A 32-year-old G{sub 3}P{sub 2002} Hispanic female presented at 14 weeks gestation for routine dating ultrasound. At that time ultrasonography revealed a septated cystic hygroma, omphalocele, bilateral talipes equinovarus, and hydrops. Amniocentesis was performed at 15 weeks and revealed a 46,XX,9p+ chromosome complement. The origin of the extra material on the terminal short arm of chromosome 9 could not be identified. Chromosome analysis was performed on the parents and the mother was found to carry the balanced translocation 46,XX,p(3;9)(q23;p13). Further analysis revealed that the fetus had inherited the derivative 9 chromosome. The fetus was therefore monosomic for 9p13-9pter and trisomic for 3q23-3pter. The patient chose to continue the pregnancy. Serial ultrasonography later demonstrated a sloping forehead, small nose, micrognathia, ventriculomegaly, possible VSD, micropenis, hypospadias, cryptorchidism and post-axial polydactyly of the hands. The fetus was delivered prematurely at 31 weeks and survived one hour. Post-mortem examination confirmed the ultrasound findings and revealed additional stigmata consistent with both 9p monosomy and 3q trisomy. A review of the literature indicates no previous report of both syndromes concurrently.

    CVS is the earliest procedure for cytogenetic analysis but the quality of metaphases obtained does not allow the characterization of subtle chromosomal anomalies. We report the application interphase fluorescence in situ hybridization for the rapid prenatal diagnosis of a subtle structural chromosome anomaly in trophoblast cells. The foetus was karyotyped because of a paternal complex chromosomal anomaly 46,XY,inv(2)(q14.3q35),ins(10;2)(q25;q36.1q36.1). Fluorescence in situ hybridization analyses were performed on interphase nuclei and metaphase chromosomes from uncultured chorionic villi using bacterial artificial chromosomes specific for the 2q chromosomal region. Direct conventional cytogenetics showed an apparently normal male karyotype, whereas fluorescence in situ hybridization analysis showed a deletion of the chromosomal region 2q36.1 and a paracentric inversion of the chromosome 2q leading to a partial monosomy 2q36.1. This strategy allowed us to offer an early and rapid chromosomal analysis for this couple leading to a better management of the pregnancy. This report demonstrates that interphase fluorescence in situ hybridization can be used in direct CVS for a rapid and early prenatal diagnosis of complex chromosomal rearrangements. 2006 S.

    We describe a series of five patients with a partial monosomy of 1p36.3 presenting with a similar syndromic appearance. The phenotype of deletion 1p36.3 patients includes abnormal facies, multiple congenital malformations, and mental retardation.The ages of the patients in our series ranged from 3 to 50 years. As the deletion is very small, detection in the present cases relied upon high resolution G-band analyses and was confirmed with FISH in cases 3 and 5. Patients 2 and 3 were diagnosed as adults; thus smaller deletions in 1p36.33 may be associated with longer life expectancy, but include the critical region for the above phenotype. We noted that the dysmorphic features of the patients are more prominent with older age and are difficult to appreciate in infancy. Observation of this specific 1p36 appears as a white, terminal G-band; detection of a small partial deletion or rearrangement may require greater than 550 band level resolution. FISH utilizing a probe to 1pter can facilitate and confirm these analyses.

    Donor cell leukemia is a rare complication of allogeneic hematopoietic stem cell transplantation (HSCT), which may result from the development of a new malignancy in previously healthy donor cells after transplant into the recipient, or it may derive from the transmission of an occult leukemia from donor to recipient. We report a case of donor derived 20q11.2 deletion in a male patient who received an allogeneic HSCT from his HLA-identical sister for the treatment of his chronic lymphocytic leukemia. Bone marrow cells from the donor were found to contain the 20q deletion that expanded over time, but which was absent in her peripheral blood cells. Although cases of donor cell leukemia after HSCT have been reported, in this case there has been no evidence of an associated hematologic neoplasm in either the donor or recipient. Pre-transplant donor bone marrow evaluations are not practical or warranted, however the finding of new cytogenetic abnormalities after transplant mandates a thorough evaluation of the donor.

    Full Text Available Genomic amplification of 19q12 occurs in several cancer types including ovarian cancer where it is associated with primary treatment failure. We systematically attenuated expression of genes within the minimally defined 19q12 region in ovarian cell lines using short-interfering RNAs (siRNA to identify driver oncogene(s within the amplicon. Knockdown of CCNE1 resulted in G1/S phase arrest, reduced cell viability and apoptosis only in amplification-carrying cells. Although CCNE1 knockdown increased cisplatin resistance in short-term assays, clonogenic survival was inhibited after treatment. Gain of 20q11 was highly correlated with 19q12 amplification and spanned a 2.5 Mb region including TPX2, a centromeric protein required for mitotic spindle function. Expression of TPX2 was highly correlated with gene amplification and with CCNE1 expression in primary tumors. siRNA inhibition of TPX2 reduced cell viability but this effect was not amplicon-dependent. These findings demonstrate that CCNE1 is a key driver in the 19q12 amplicon required for survival and clonogenicity in cells with locus amplification. Co-amplification at 19q12 and 20q11 implies the presence of a cooperative mutational network. These observations have implications for the application of targeted therapies in CCNE1 dependent ovarian cancers.

    Monosomy of chromosome 7 is the most frequent autosomal monosomy in acute myeloid leukemia (AML), where it associates with poor clinical outcomes. However, molecular features associated with this sole monosomy subtype (-7 AML), which may give insights into the basis for its poor prognosis, have not been characterized. In this study, we analyzed 36 cases of -7 AML for mutations in 81 leukemia/cancer-associated genes using a customized targeted next-generation sequencing panel (Miseq). Global gene and miRNA expression profiles were also determined using paired RNA and small RNA sequencing data. Notably, gene mutations were detected in all the major AML-associated functional groups, which include activated signaling, chromatin remodeling, cohesin complex, methylation, NPM1, spliceosome, transcription factors, and tumor suppressors. Gene mutations in the chromatin remodeling groups were relatively more frequent in patients <60 years of age, who also had less mutations in the methylation and spliceosome groups compared with patients ≥60 years of age. Novel recurrent mutational events in AML were identified in the SMARCA2 gene. In patients ≥60 years of age, the presence of spliceosome mutations associated with a lower complete remission rate (P = 0.03). RNA sequencing revealed distinct gene and miRNA expression patterns between the sole -7 and non -7 AML cases, with reduced expression, as expected, of many genes and miRNAs mapped to chromosome 7, and overexpression of ID1, MECOM, and PTPRM, among others. Overall, our findings illuminate a number of molecular features of the underlying aggressive pathobiology in -7 AML patients.

    Summary Bipolar disorder (BPD) is a highly heritable polygenic disorder. Recent enrichment analyses suggest that there may be true risk variants for BPD among the expression quantitative trait loci (eQTL) in the brain. Aims We sought to assess the impact of eQTL variants on BPD risk by combining data from both BPD genome-wide association study (GWAS) and brain eQTL. Method To detect single-nucleotide polymorphisms (SNPs) that influence expression levels of genes associated with BPD, we jointly analyzed data from a BPD GWAS (7,481 cases and 9,250 controls) and a genome-wide brain (cortical) eQTL (193 healthy controls) using a Bayesian statistical method, with independent follow-up replications. The identified risk SNP was then further tested for association with hippocampal volume (N=5,775) and cognitive performance (N=342) among healthy subjects. Results Integrative analysis revealed a significant association between a brain eQTL rs6088662 in 20q11.22 and BPD (Log Bayes Factor=5.48; BPD p-val=5.85×10−5). Follow-up studies across multiple independent samples confirmed the association of the risk SNP (rs6088662) with gene expression and BPD susceptibility (p-val=3.54×10−8). Further exploratory analysis revealed that rs6088662 is also associated with hippocampal volume and cognitive performance in healthy subjects. Conclusions Our findings suggest that 20q11.22 is likely a risk region for BPD, highlighting the informativeness of integrating functional annotation of genetic variants for gene expression in advancing our understanding of the biological basis underlying complex diseases such as BPD.

    Carriers of completely balanced chromosomal translocations have all necessary genetic information. Nevertheless, because of the possibility of maldistribution during gametogenesis, they are at increased risk for infertility, miscarriage, stillbirth or having a child with congenital anomalies including mental retardation. As postnatal clinical reports are infrequent, prediction of clinical course for specific unbalanced karyotypes diagnosed during pregnancy remains difficult. Here, we report the 6th case of partial trisomy 6p and partial monosomy 20p due to an unbalanced adjacent-1 segregation of the rare familial translocation t(6;20)(p21;p13). We give a thorough clinical description of the present case, demonstrating broad phenotypic overlap with the 5 previously published cases reviewed here, providing important data on postnatal outcome.

    Monogenic human disorders have been used as paradigms for complex genetic disease and as tools for establishing important insights into mechanisms of gene regulation and transcriptional control. Maturity-onset diabetes of the young (MODY) is a monogenic dominantly inherited form of diabetes that is characterized by defective insulin secretion from the pancreatic beta-cells. A wide variety of mutation types in five different genes have been identified that result in this condition. There have been no reports of a chromosome deletion or translocation resulting in MODY. We report a pedigree where MODY cosegregates with a balanced translocation [karyotype 46, XX t(3;20) (p21.2;q12)]. The chromosome 20 break point, 20q12, is within the region of one of the known MODY genes, hepatocyte nuclear factor-4alpha (HNF4A). Fluorescence in situ hybridization analysis demonstrated that the break point does not disrupt the coding region of this gene, but it lies at least 6 kb upstream of the conventional promoter (P1). We propose that this mutation disrupts the spatial relationship between the recently described alternate distal pancreatic promoter (P2) and HNF4A. This is the first case of MODY due to a balanced translocation, and it provides evidence to confirm the crucial role of an upstream regulator of HNF4A gene expression in the beta-cell.

    A retrospective study from November 2004 to May 2012, conducted at the Obstetric Clinic of Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo (HC-FMUSP), which included 92 singleton pregnancies with prenatal diagnosis of trisomy of chromosome 21 (T21), 18, 13 (T13/18) and monosomy X (45X), with diagnosis performed until the 26th week of pregnancy. The aim of the study was to describe the frequency and to investigate predictors of spontaneous fetal death (FD). Diagnosis (T21, n=36; T13/18, n=25; 45X, n=31) was made at a mean gestational age of 18.3±3.7 weeks, through chorionic villus biopsy (n=22,24%), amniocentesis (n=66, 72%) and cordocentesis (n=4, 4%). Major malformations were present in 45 (49%); with hydrops in 32 (35%) fetuses, more frequently in 45X [n=24/31, 77% vs. T21 (n=6/36, 17%) and T13/18 (n=2/25, 8%), p<0.001]. Specialized fetal echocardiography was performed in 60% (55/92). Of these, 60% (33/55) showed changes in heart morphology and/or function. Fetuses with T13/18 had a higher incidence of cardiac anomalies [60 vs. 25% (T21) and 29% (45X), p= 0.01]. FD occurred in 55 (60%) gestations, being more frequent in 45X [n=26/31, 84% vs. T21 (n=13/36, 36%) and T13/18 (n=16/25, 64%), p<0.01]. Stepwise analysis showed a correlation between hydrops and death in fetuses with T21 (LR= 4.29; 95CI=1.9-8.0, p<0.0001). In fetuses with 45X, the presence of echocardiographic abnormalities was associated with lower risk of FD (LR= 0.56; 95CI=0.27- 0.85, p=0.005). No predictive factors were identified in the T13/18 group. Intra- uterine lethality of aneuploid fetuses is high. Occurrence of hydrops increases risk of FD in pregnancies with T21. In pregnancies with 45X, the occurrence of echocardiographic changes reduces this risk.

    The dic(17;20) is a recurrent unbalanced translocation occurring rarely in myelodysplastic syndromes and acute myeloid leukemia. We have studied eleven cases with the dic(17;20) or a more complex derivative, all of which showed deletion of 17p and 20q material. The tumor suppressor gene TP53 was not always lost, supporting a more distal gene as the target of these 17p deletions. All derivatives could be interpreted as having initially been formed as a dicentric chromosome, those with a larger amount of material between the centromeres having undergone further rearrangement to stabilize the chromosome while retaining proximal 17p and proximal 20q material. We propose that critical sequences on both 17p and 20q proximal to the sites of deletion must be retained during the critical 17p and 20q deletions. This would explain the excess of dicentric chromosomes resulting from 17;20 translocation, and the apparent stabilization of the unstable derivatives by further rearrangements which preserve 17p and 20q material.

    Genome-wide association studies (GWAS) of breast cancer defined by hormone receptor status have revealed loci contributing to susceptibility of estrogen receptor (ER)-negative subtypes. To identify additional genetic variants for ER-negative breast cancer, we conducted the largest meta-analysis of ER-negative disease to date, comprising 4754 ER-negative cases and 31 663 controls from three GWAS: NCI Breast and Prostate Cancer Cohort Consortium (BPC3) (2188 ER-negative cases; 25 519 controls of European ancestry), Triple Negative Breast Cancer Consortium (TNBCC) (1562 triple negative cases; 3399 controls of European ancestry) and African American Breast Cancer Consortium (AABC) (1004 ER-negative cases; 2745 controls). We performed in silico replication of 86 SNPs at P ≤ 1 × 10-5 in an additional 11 209 breast cancer cases (946 with ER-negative disease) and 16 057 controls of Japanese, Latino and European ancestry. We identified two novel loci for breast cancer at 20q11 and 6q14. SNP rs2284378 at 20q11 was associated with ER-negative breast cancer (combined two-stage OR = 1.16; P = 1.1 × 10−8) but showed a weaker association with overall breast cancer (OR = 1.08, P = 1.3 × 10–6) based on 17 869 cases and 43 745 controls and no association with ER-positive disease (OR = 1.01, P = 0.67) based on 9965 cases and 22 902 controls. Similarly, rs17530068 at 6q14 was associated with breast cancer (OR = 1.12; P = 1.1 × 10−9), and with both ER-positive (OR = 1.09; P = 1.5 × 10−5) and ER-negative (OR = 1.16, P = 2.5 × 10−7) disease. We also confirmed three known loci associated with ER-negative (19p13) and both ER-negative and ER-positive breast cancer (6q25 and 12p11). Our results highlight the value of large-scale collaborative studies to identify novel breast cancer risk loci. PMID:22976474

    Maturity-onset diabetes of the young (MODY) is a form of non-insulin-dependent diabetes mellitus characterized by an early age of onset, usually before 25 years of age, and an autosomal dominant mode of inheritance. The largest and best-studies MODY pedigree is the TW family. The majority of the diabetic subjects in this pedigree has a reduced and delayed insulin-secretory response to glucose, and it has been proposed that this abnormal response is the manifestation of the basic genetic defect that leads to diabetes. Using DNA from members of the TW family, the authors tested more than 75 DNA markers for linkage with MODY. A DNA polymorphism in the adenosine deaminase gene (ADA) on the long arm of chromosome 20 was found to cosegregate with MODY. The maximum logarithm of adds (lod score) for linkage between MODY and ADA was 5.25 at a recombination fraction of 0.00. These results indicate that the odds are {gt}178,000:1 that the gene responsible for MODY is this family is tightly linked to the ADA gene on chromosome 20q.

    Chromosome 20q12-q13.1 has been linked to type 2 diabetes (T2D) in multiple populations. We examined the influence of genes in this region on T2D and BMI in two European American case-control populations. SNPs were genotyped in 300 diabetic patients and 310 controls. A subset of 72 SNPs were further genotyped in 470 cases and 442 controls. All genes examined showed evidence of association with T2D in the initial sample (additive P-value [P(a)]=0.00090-0.045). SNPs near PREX1 were also associated in the second case-control population (P(a)=0.017-0.042). The combined analysis resulted in the same SNPs, among others, associated with T2D (P(a)=0.0013-0.041). Stratification analysis by T2D status showed that association with BMI was observed solely in cases (P(a)=0.0018-0.041). Mediation testing revealed that 30-40% of the effects of these SNPs on T2D were significantly mediated by BMI. SNPs near PREX1 may contribute to T2D susceptibility mediated through effects of adiposity in European Americans. Published by Elsevier Inc.

    We report on a patient with dup(17p) and monosomy (10q) resulting from a familial translocation. Manifestations typical of both syndromes were present. The overall development of this patient was better by comparison with similar reported cases of either anomaly. Our evaluation detected severe gross motor delay and signs of a demyelinating peripheral neuropathy. This patient is trisomic for the region of 17p which includes the peripheral myelin protein-22 (PMP-22) gene, known to be duplicated in Charcot-Marie-Tooth neuropathy type 1A (CMT1A). Our analysis in this patient suggests that trisomy for the PMP-22 gene led to the demyelinating neuropathy and contributed to his severe motor development delay. 33 refs., 3 figs., 1 tab.

    Full Text Available Abstract Background Oncogene amplification and overexpression occur in tumor cells. Amplification status may provide diagnostic and prognostic information and may lead to new treatment strategies. Chromosomal regions 8p12, 8q24, 11q13, 17q12 and 20q13 are recurrently amplified in breast cancers. Methods To assess the frequencies and clinical impact of amplifications, we analyzed 547 invasive breast tumors organized in a tissue microarray (TMA by fluorescence in situ hybridization (FISH and calculated correlations with histoclinical features and prognosis. BAC probes were designed for: (i two 8p12 subregions centered on RAB11FIP1 and FGFR1 loci, respectively; (ii 11q13 region centered on CCND1; (iii 12p13 region spanning NOL1; and (iv three 20q13 subregions centered on MYBL2, ZNF217 and AURKA, respectively. Regions 8q24 and 17q12 were analyzed with MYC and ERBB2 commercial probes, respectively. Results We observed amplification of 8p12 (amplified at RAB11FIP1 and/or FGFR1 in 22.8%, 8q24 in 6.1%, 11q13 in 19.6%, 12p13 in 4.1%, 17q12 in 9.9%, 20q13Z (amplified at ZNF217 only in 9.9%, and 20q13Co (co-amplification of two or three 20q13 loci in 8.5% of cases. The 8q24, 12p13, and 17q12 amplifications were correlated with high grade. The most frequent single amplifications were 8p12 (9.8%, 8q24 (3.3% and 12p13 (3.3%, 20q13Z and 20q13Co (1.6% regions. The 17q12 and 11q13 regions were never found amplified alone. The most frequent co-amplification was 8p12/11q13. Amplifications of 8p12 and 17q12 were associated with poor outcome. Amplification of 12p13 was associated with basal molecular subtype. Conclusion Our results establish the frequencies, prognostic impacts and subtype associations of various amplifications and co-amplifications in breast cancers.

    Full Text Available The trisomy of human chromosome 21 (Hsa21, which causes Down syndrome (DS, is the most common viable human aneuploidy. In contrast to trisomy, the complete monosomy (M21 of Hsa21 is lethal, and only partial monosomy or mosaic monosomy of Hsa21 is seen. Both conditions lead to variable physiological abnormalities with constant intellectual disability, locomotor deficits, and altered muscle tone. To search for dosage-sensitive genes involved in DS and M21 phenotypes, we created two new mouse models: the Ts3Yah carrying a tandem duplication and the Ms3Yah carrying a deletion of the Hspa13-App interval syntenic with 21q11.2-q21.3. Here we report that the trisomy and the monosomy of this region alter locomotion, muscle strength, mass, and energetic balance. The expression profiling of skeletal muscles revealed global changes in the regulation of genes implicated in energetic metabolism, mitochondrial activity, and biogenesis. These genes are downregulated in Ts3Yah mice and upregulated in Ms3Yah mice. The shift in skeletal muscle metabolism correlates with a change in mitochondrial proliferation without an alteration in the respiratory function. However, the reactive oxygen species (ROS production from mitochondrial complex I decreased in Ms3Yah mice, while the membrane permeability of Ts3Yah mitochondria slightly increased. Thus, we demonstrated how the Hspa13-App interval controls metabolic and mitochondrial phenotypes in muscles certainly as a consequence of change in dose of Gabpa, Nrip1, and Atp5j. Our results indicate that the copy number variation in the Hspa13-App region has a peripheral impact on locomotor activity by altering muscle function.

    Partial trisomy 8q is rare and has distinctive clinical features, including severe mental retardation, growth impairment, dysmorphic facial appearances, cleft palate, congenital heart disease, and urogenital anomalies. Partial monosomy 13q is a rare genetic disorder displaying a variety of phenotypic characteristics including mental retardation, dysmorphic facial features, and congenital anomalies. Here, we describe for the first time clinical observations and cytogenetic analysis of a patient with a concomitant occurrence of partial trisomy of 8q (8q21.3→qter) and partial monosomy 13q(13q34→qter). The patient was a female neonate with facial dysmorphia, agenesis of the corpus callosum, cleft palate, and congenital heart disease. G-band standard karyotype was 46,XX,add(13)(q34). To determine the origin of additional genomic gain in chromosome 13, array comparative genomic hybridization (CGH) was performed. Array CGH showed a 56.8 Mb sized gain on chromosome 8q and a 0.28 Mb sized loss on chromosome 13q. Therefore, the final karyotype of the patient was defined as 46,XX, der(13)t(8;13)(q21.3;q34). In conclusion, we described the clinical and cytogenetic analysis of the patient with concomitant occurrence of partial trisomy 8q and partial monosomy 13q delineated by array CGH. This report suggests that the array CGH would be a valuable diagnostic tool for identifying the origin of small additional genetic materials.

    We have carried out a detailed sequence and functional analysis of a novel human facilitative glucose transporter, designated GLUT10, located in the Type 2 diabetes-linked region of human chromosome 20q12-13.1. The GLUT10 gene is located between D20S888 and D20S891 and is encoded by 5 exons spanning 26.8 kb of genomic DNA. The human GLUT10 cDNA encodes a 541 amino acid protein that shares between 31 and 35% amino acid identity with human GLUT1-8. The predicted amino acid sequence of GLUT10 is nearly identical in length to the recently described GLUT9 homologue, but is longer than other known members of the GLUT family. In addition, we have cloned the mouse cDNA homolog of GLUT10 that encodes a 537 amino acid protein that shares 77.3% identity with human GLUT10. The amino acid sequence probably has 12 predicted transmembrane domains and shares characteristics of other mammalian glucose transporters. Human and mouse GLUT10 retain several sequence motifs characteristic of mammalian glucose transporters including VP497ETKG in the cytoplasmic C-terminus, G73R[K,R] between TMD2 and TMD3 (PROSITE PS00216), VD92RAGRR between TMD8 and TMD9 (PROSITE PS00216), Q242QLTG in TMD7, and tryptophan residues W430 (TMD10) and W454 (TMD11), that correspond to trytophan residues previously implicated in GLUT1 cytochalasin B binding and hexose transport. Neither human nor mouse GLUT10 retains the full P[E,D,N]SPR motif after Loop6 but instead is replaced with P186AG[T,A]. A PROSITE search also shows that GLUT10 has lost the SUGAR TRANSPORT 2 pattern (PS00217), a result of the substitution G113S in TMD4, while all other known human GLUTs retain the glycine and the pattern match. The significance of this substitution is unknown. Sites for N-linked glycosylation are predicted at N334ATG between TMD8 and TMD9 and N526STG in the cytoplasmic C-terminus. Northern hybridization analysis identified a single 4.4-kb transcript for GLUT10 in human heart, lung, brain, liver, skeletal muscle

    Full Text Available Abstract Introduction Therapy-related acute myeloid leukemia occurs as a complication of treatment with chemotherapy, radiotherapy, immunosuppressive agents or exposure to environmental carcinogens. Case presentation We report a case of therapy-related acute myeloid leukemia in a 37-year-old Turkish woman in complete remission from breast cancer. Our patient presented to our facility with fatigue, fever, sore throat, peripheral lymphadenopathy, and moderate hepatosplenomegaly. On peripheral blood and bone marrow aspirate smears, monoblasts were present. Immunophenotypic analysis of the bone marrow showed expression of CD11b, CD13, CD14, CD15, CD33, CD34, CD45 and human leukocyte antigen-DR, findings compatible with the diagnosis of acute monoblastic leukemia (French-American-British classification M5a. Therapy-related acute myeloid leukemia developed three years after adjuvant chemotherapy consisting of an alkylating agent, cyclophosphamide and DNA topoisomerase II inhibitor, doxorubicin and adjuvant radiotherapy. Cytogenetic analysis revealed a 46, XX, deletion 7 (q22q34, deletion 20 (q11.2q13.1 karyotype in five out of 20 metaphases and inversion 16 was detected by fluorescence in situhybridization. There was no response to chemotherapy (cytarabine and idarubicin, FLAG-IDA protocol, azacitidine and our patient died in the 11th month after diagnosis. Conclusions The median survival in therapy-related acute myeloid leukemia is shorter compared to de novoacute myeloid leukemia. Also, the response to therapy is poor. In therapy-related acute myeloid leukemia, complex karyotypes have been associated with abnormalities of chromosome 5, rather than 7. To the best of our knowledge, this is the first case of therapy-related acute myeloid leukemia showing the co-presence of deletion 7q, 20q and the inversion 16 signal.

    Failure to establish the left-right embryonic axis results in abnormalities of laterality; situs solitus is replaced by situs inversus totalis or various degrees of heterotaxy involving the heart, great vessels, lungs, liver, spleen, and/or bowel. Laterality syndromes are likely to be genetically heterogeneous although specific human genes have not been identified. Families with dominant, recessive, and X-linked laterality syndromes have been reported as well as individuals with situs abnormalities and chromosome rearrangements. The latter offer the possibility of narrowing the gene search to specific chromosome regions. A recent report described an infant with polysplenia syndrome and a paracentric inversion of chromosome 11 [46,XX,inv(11)(q13q25)pat]. We report the second case of a child with laterality abnormalities and a chromosome rearrangement involving a similar breakpoint on chromosome 11. The proband is a 6 y/o female with mental retardation, dysmorphic features, pulmonic stenosis, asplenia, Hirschsprung disease, and a balanced, reciprocal translocation involving chromosomes 11 and 20 [46,XX,t(11;20)(q13,1;q13.13)pat]. Using DNA probes we have excluded uniparental disomy for chromosomes 11 and 20. If a gene for determination of laterality lies in the 11q13 region, the proband`s abnormalities could be the result of her receiving an allele disrupted by the paternal translocation as well as a mutant allele from her mother. To investigate this possibility, we are studying the segregation of maternal chromosome 11 markers in the proband and her balanced carrier and non-carrier siblings.

    We report the first trimester three-dimensional ultrasonographic findings in a 13-week-old fetus with complex phenotype and a de novo 4.7 Mb multigene deletion encompassing chromosome region 20q13.13-q13.2 detected by chromosomal microarray. Fetal sonography detected radial-ray anomalies in the form of bilateral absence of thumbs and the left club hand deformity. The presence of single atrioventricular canal instead of the atrial septal defect typical for Holt-Oram syndrome pointed us to rather suspect the SALL4 related diseases. Central nervous system anomaly in the form of enlarged lateral brain ventricles with choroid plexus shifted backwards was not previously reported as a part of SALL4 related disorders. The pregnancy was terminated at 14 + 3 weeks of pregnancy and the autopsy confirmed ultrasonographic findings. Deleted region included 38 genes, where only SALL4, ADNP and KCNB1 heterozygote pathogenic variants were described to be cause of syndromic forms. Radial ray anomalies are common part of clinical picture of SALL4 related disorders. Despite the lack of prenatally described cases, we hypothesized that maldevelopment of lateral brain ventriculomegaly could be very early sonographic sign of disturbed ADNP expression causing Helsmoortel-Van der Aa syndrome, but in some extent also of KCNB1 related early-onset epileptic encephalopathy. Furthermore, the possible dosage-dependent influence of recessive genes located in this region cannot be also excluded. The use of genome-wide technologies enables the detection of subtle chromosomal imbalances and more precise familial genetic counseling regarding actual and future pregnancies.

    Blepharophimosis is a rare congenital anomaly of the palpebral fissure which is often associated with mental retardation and additional malformations. We report on a boy with blepharophimosis, ptosis and severe mental retardation carrying an unbalanced 4;10 translocation with terminal duplication of 10q [dup(10)(q25.1-->qter)] and monosomy of a small terminal segment of chromosome 4q [del(4)(34.3-->qter)]. Detailed clinical examination and review of the literature showed that the phenotype of the patient was mainly determined by the dup(10q). This paper reviews the chromosomal aberrations associated with BMR (blepharophimosis mental retardation) phenotypes. Searching different databases and reviewing the literature revealed 14 microscopically visible aberrations (among them UPD(14)pat) and two submicroscopic rearrangements causing blepharophimosis and mental retardation (BMR) syndrome. Some of these rearrangements-like the terminal dup(10q) identified in our patient or interstitial del(2q)-are associated with clearly defined phenotypes and can be well distinguished from each other on basis of clinical examination. This paper should assist clinicians and cytogeneticists when evaluating patients with BMR syndrome.

    Full Text Available Sjögren’s syndrome (SS is a chronic slowly progressive autoimmune disorder characterized by symptoms of oral and ocular dryness, exocrine dysfunction, and lymphocytic infiltration of exocrine glands. Multiple myeloma (MM is a bone-marrow-based malignant neoplasm of plasma cells associated with serum/urine monoclonal paraproteins and lytic skeletal lesions. There have been very few reported cases of MM, who had SS as the first presentation. We report a case of a woman diagnosed with Sjögren’s syndrome, who was later suspected to have multiple myeloma on serum protein electrophoresis. Fluorescence in situ hybridization (FISH was carried out to check for deletions of loci 13q14.3, ATM, p53, and IGH (14q32 rearrangements on a bone marrow aspirate. Monosomy 13 was observed in 49% of cells, and a rearrangement at the IGH locus was seen in 42% of cells. To determine the partner chromosome associated with the IGH rearrangement, further FISH tests were set up for t(4;14(p16;q32 followed by t(14;16(q32;q22 on fresh slides. The test was negative for t(4;14 but positive for t(14;16 in 27% of cells. This confirmed the diagnosis of MM. We report the first case from India, having an association of Sjögren’s syndrome with multiple myeloma, which showed t(14;16 and monosomy 13 by FISH analysis.

    Increased nuchal translucency (NT) during the first trimester of pregnancy is a useful marker to detect chromosomal abnormalities. Here, we report a prenatal case with molecular cytogenetic characterisation of an abnormal derivative chromosome 9 identified through NT. Amniocentesis was performed because of an increased NT (4.4 mm) and showed an abnormal de novo 46,XX,add(9)(p24.3) karyotype. To characterise the origin of the small additional material on 9p, we performed a microarray comparative genomic hybridisation (microarray CGH) using a genomic DNA array providing an average of 1 Mb resolution. Microarray CGH showed a deletion of distal 9p and a trisomy of distal 17q. These results were confirmed by FISH analyses. Microarray CGH provided accurate information on the breakpoint regions and the size of both distal 9p deletion and distal 17q trisomy. The fetus was therefore a carrier of a de novo derivative chromosome 9 arising from a t(9;17)(p24.3;q24.3) translocation and generating a monosomy 9p24.3-pter and a trisomy 17q24.3-qter. This case illustrates that microarray CGH is a rapid, powerful and sensitive technology to identify small de novo unbalanced chromosomal abnormalities and can be applied in prenatal diagnosis. 2006 John Wiley & Sons, Ltd.

    Full Text Available Abstract Introduction Glycogen storage disease type Ib is an autosomal recessive transmitted disorder of glycogen metabolism caused by mutations in the glucose-6-phosphate translocase gene on chromosome 11q23 and leads to disturbed glycogenolysis as well as gluconeogenesis. Besides hepatomegaly, growth retardation, hypoglycemia, hyperlactatemia, hyperuricemia and hyperlipidemia, patients suffer from neutropenia associated with functional defects predisposing for severe infections. In order to attenuate these complications, long-term treatment with granulocyte colony-stimulating factor is common but this is associated with an increased risk for acute myeloid leukemia or myelodysplastic syndromes in patients with inherited bone marrow failures such as severe congenital neutropenia. Onset of these myeloid malignancies is linked to cytogenetic aberrations involving chromosome 7. In addition, granulocyte colony-stimulating factor is known to stimulate proliferation of monosomy 7 cells in vitro. To our knowledge, we report for the first time a case report of a patient with glycogen storage disease type Ib, who developed acute myeloid leukemia with a classical monosomy 7 and acute myeloid leukemia-associated translocation t(3;8(q26;q24 after 14 years of continuous treatment with granulocyte colony-stimulating factor. Case presentation A 28-year-old Turkish man with glycogen storage disease type Ib was admitted to our department because of dyspnea and increasing fatigue. He also presented with gum bleeding, bone pain in his legs, night sweats, recurrent episodes of fever with temperatures up to 39°C and hepatosplenomegaly. A blood count taken on the day of admission showed pancytopenia and a differential count displayed 30% blasts. A bone marrow biopsy was taken which showed a hypercellular marrow with dysplastic features of all three cell lines, while blast count was 20%.

  20. Due process traditionalism.

    2008-06-01

    In important cases, the Supreme Court has limited the scope of "substantive due process" by reference to tradition, but it has yet to explain why it has done so. Due process traditionalism might be defended in several distinctive ways. The most ambitious defense draws on a set of ideas associated with Edmund Burke and Friedrich Hayek, who suggested that traditions have special credentials by virtue of their acceptance by many minds. But this defense runs into three problems. Those who have participated in a tradition may not have accepted any relevant proposition; they might suffer from a systematic bias; and they might have joined a cascade. An alternative defense sees due process traditionalism as a second-best substitute for two preferable alternatives: a purely procedural approach to the Due Process Clause, and an approach that gives legislatures the benefit of every reasonable doubt. But it is not clear that in these domains, the first-best approaches are especially attractive; and even if they are, the second-best may be an unacceptably crude substitute. The most plausible defense of due process traditionalism operates on rule-consequentialist grounds, with the suggestion that even if traditions are not great, they are often good, and judges do best if they defer to traditions rather than attempting to specify the content of "liberty" on their own. But the rule-consequentialist defense depends on controversial and probably false assumptions about the likely goodness of traditions and the institutional incapacities of judges.

    The history of medicine is filled with stories of tireless researchers who failed to get credit for their hard work. Examples of this include Rosalind Franklin, who helped to elucidate the structure of DNA; Frederick Banting, who helped to discover insulin; and Jay McLean, who discovered heparin. The founding of the field of vascular surgery provides one of the most vivid examples of uncredited work. Even though Alexis Carrel was an unpaid, untitled assistant in Charles Guthrie's laboratory, it was Carrel alone who received a Nobel Prize for their work. In an attempt to give credit where due, the reasons for this injustice are described. Copyright © 2016 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

    The human adenosine deaminase gene has been characterized in detail. The adenosine gene product, as part of the purine catabolic pathway, catalyzes the irreversible deamination of adenosine and deoxyadenosine. Deficiency of this activity in humans is associated with an autosomal recessive form of severe combined immunodeficiency disease. Recently, this genetic deficiency disease has been targeted for the first attempts at gene therapy in humans. Using the polymerase chain reaction (PCR), a fragment of the expected size (160 bp) was amplified from human genomic DNA.

    @@ Stroke due to ‘cerebral vein thrombosis' (CVT) is commonly used to refer to thrombosis of the cerebral venous system, including either dural venous sinuses, or deep and superficial (cortical) cerebral veins. CVT are frightening events due to the severity of their clinical manifestations and their high mortality rate (up to 30% in some casereports).The clinical signs and symptoms of CVT are relatively nonspecific: they include headache, papilledema, vomiting,seizures, focal neurological deficits (motor or sensory) and impaired consciousness. CVT has long been considered as rare and mostly infection-related event; moreover, due to its nonspecific clinical manifestations, the diagnosis has been difficult, delayed and could often be made only post mortem.

    "In this paper, a longitudinal data set covering 5% of all Danish wage earners over a 9-year period is used to shed light on the observed wage differentials due to gender. A human capital model is used to isolate the effects of changes in experience, schooling and unemployment, together with other factors.... Despite the observation from macro statistics that women have had the highest observed increases in wage rates, the models show that this increase is mainly due to an improvement in their background characteristics and that men still receive a higher return to their characteristics. The main difference between genders appears to be that female workers do not, in general, get any return to their experience. The estimates also show negative effects on the wage rate of previous spells of unemployment." excerpt

    2012-02-01

    Maternal mortality is an important indicator of adequacy of health care in our society. Improvements in the obstetric care system as well as advances in technology have contributed to reduction in maternal mortality rates. Trauma complicates up to 7% of all pregnancies and has emerged as the leading cause of maternal mortality, becoming a significant concern for the public health system. Maternal mortality secondary to trauma can often be prevented by coordinated medical care, but it is essential that caregivers recognize the unique situation of providing simultaneous care to 2 patients who have a complex physiologic relationship. Optimal management of the pregnant trauma victim requires a multidisciplinary team, where the obstetrician plays a central role. This review focuses on the incidence of maternal mortality due to trauma, the mechanisms involved in traumatic injury, the important anatomic and physiologic changes that may predispose to mortality due to trauma, and finally, preventive strategies that may decrease the incidence of traumatic maternal death.

    2001-02-01

    We propose a method called ‘coherence swapping’ which enables us to create superposition of a particle in two distinct paths, which is fed with initially incoherent, independent radiation. This phenomenon is also present for the charged particles, and can be used to swap the effect of flux line due to the Aharonov–Bohm effect. We propose an optical version of experimental set-up to test the coherence swapping. The phenomenon, which is simpler than entanglement swapping or teleportation, raises some fundamental questions about the true nature of wave-particle duality, and also opens up the possibility of studying the quantum erasure from a new angle.

    Each year in the United States, an estimated 800 to 1,400 people are murdered at work, and an unknown number of nonfatal injuries due to workplace violence occur. Based on Ohio's workers' compensation claims from 1983 through 1985, police officers, gasoline service station employees, employees of the real estate industry, and hotel/motel employees were found to be at the highest risk for occupational violent crime (OVC) injury and death. Grocery store employees, specifically those working in convenience food stores, and employees of the real estate industry had the most reported rapes. Four previously unidentified industries at increased risk of employee victimization were described. Identification of industries and occupations at high risk for crime victimization provides the opportunity to focus preventive strategies to promote employee safety and security in the workplace.

  3. Collisional Aggregation due to Turbulence

    CERN Document Server

    Pumir, Alain

    2015-01-01

    Collisions between particles suspended in a fluid play an important role in many physical processes. As an example, collisions of microscopic water droplets in clouds are a necessary step in the production of macroscopic raindrops. Collisions of dust grains are also conjectured to be important for planet formation in the gas surrounding young stars, and also to play a role in the dynamics of sand storms. In these processes, collisions are favoured by fast turbulent motions. Here we review recent advances in the understanding of collisional aggregation due to turbulence. We discuss the role of fractal clustering of particles, and caustic singularities of their velocities. We also discuss limitations of the Smoluchowski equation for modelling these processes. These advances lead to a semi-quantitative understanding on the influence of turbulence on collision rates, and point to deficiencies in the current understanding of rainfall and planet formation.

    2007-06-01

    Familial Mediterranean fever (FMF) is an ethnically restricted disease with an autosomal recessive inheritance characterized by recurrent attacks of fever, painful manifestations in the abdomen, chest and joints. The disease affects mainly non-Ashkenazi Jews, Armenians, Turks Arabs and other people of Mediterranean origin. The disease may present at any age, more than 80% of patients being symptomatic by the age of 20. Although the inflammatory attacks that characterize the disease may sometimes be debilitating, secondary (AA) amyloidosis remains the most serious manifestation of FMF causing considerable morbidity due mostly to nephropathic amyloidosis. The largest series of secondary amyloidosis in FMF have been reported from Turkey. The pathophysiological steps in progressing a patient from FMF to amyloidosis are not definitely known. Daily treatment with colchicine can prevent both the attacks and amyloid deposition but no effective alternative treatment exists for colchicine resistant cases. Meanwhile more population based epidemiological and genetic data should be gathered by worldwide collaborative studies to elucidate the link between FMF and amyloidosis and to develop alternative therapies.

    Within the drug safety program in psychiatry AMSP ( Arzneimittelsicherheit in der Psychiatrie), severe adverse drug reactions (ADRs) are assessed. Currently 35 psychiatric hospitals and departments are participating in detecting severe ADRs. This paper focuses on prolactin-dependent ADRs such as gynecomastia and galactorrhea due to psychotropic medications. Related to the number of patients surveyed (122,562 from 1993 to 2000), these are rare events (0.03 % or 35 cases). Imputed drugs were mostly antipsychotics, but antidepressants were also imputed in single cases. In the group of antipsychotics, relative frequencies of galactorrhea were highest for amisulpride and risperidone and corresponded to the degree of D2 binding. Galactorrhea assessed as "severe" was accompanied by distressing symptoms such as pain, tension, enlargement of breasts, or soaked clothing. The AMSP data contribute to the knowledge on endocrine ADRs by the large number of patients examined and help clinicians select the appropriate drug if their patients have been prone to for these ADRs in the past.

    Full Text Available Introduction: Esophageal carcinoma is the scourge of human beings. Pulmonary compli-cations in patients who have undergone operation are common (20-30% of cases and there are no suitable tools and ways to predict these complications. Methods: During a period of 10 years, from March 1998 to February 2007, 200 patients (150 male and 50 female underwent Esophagectomy due to esophageal carcinoma in thoracic surgery ward retrospectively. Complications include the length of hospitalization, mechanical ventilation, morbidity and mortality. Patients’ risk factors include age, preoperative chemo-radiotherapy, stage of the disease and preoperative spirometry condition. Results: We grouped our patients into three categories: Normal (FEV1 ≥ 80% predicted, mildly impaired (FEV1 65% to 79% predicted, more severely impaired (FEV1 < 65% predicted.Although almost all patients had radiographic pulmonary abnormalities, significant pulmonary complications occurred in 40 patients (20% which underwent Esophagectomy. Pleural effusion and atelectasia in 160 patients (80%. 24 patients needed chest-tube insertion. 20 patients (10% developed ARDS. 14 patients (7% developed chylothorax. 20 patients (10% of patients died during their postoperative hospital stay. 30 patients (15% required mechanical ventilation for greater than 48 hours. Conclusion: We reviewed a number of preoperative clinical variables to determine whether they contributed to postoperative pulmonary complications as well as other outcomes. In general, age, impaired pulmonary function especially in those patients with FEV1 less than 65% predicted was associated with prolonged hospital length of stay (LOS. In fact pulmonary complications rate after Esophagectomy are high and there was associated mortality and morbidity.

    Otomycosis is common throughout the world but barely studied in Spain. Our objective was to determine the microbiological and epidemiological characteristics of this pathology in Cadiz (Spain) between 2005 and 2010. Samples from patients with suspicion of otomycosis underwent a direct microscopic examination and culture on different media for fungi and bacteria. Mycological cultures were incubated at 30°C for at least seven days. Identification of fungi was based on colonial morphology and microscopic examination of fungal structure. From a total of 2,633 samples, microbial growth was present in 1,375 (52.2%) and fungal isolation in 390 (28.4%). We identified 228 yeasts and 184 filamentous fungi (13.4% of positive cultures and 47.2% of otomycosis), associated with yeasts in 22 cases (5.6%). The most frequent species were Aspergillus flavus (42.4%), A. niger (35.9%), A. fumigatus (12.5%), A. candidus (7.1%), A. terreus (1.6%), and Paecilomyces variotii (0.5%). Infection was predominant in men (54.9%) and patients beyond 55 years old (46.8%). The most common clinical symptoms were itching (98.9%), otalgia (59.3%), and hypoacusis (56.0%). Fall season reported the lowest number of cases (20.1%). Incidence of otomycosis and fungi producing otomycosis vary within the distinct geographical areas. In Cadiz, this infection is endemic due to warm temperatures, high humidity, sea bathing, and wind, which contributes to disseminate the conidia. Despite Aspergillus niger has been reported as the main causative agent, A. flavus is predominant in Cadiz. Although infection is usually detected in warm months, we observed a homogeneous occurrence of otomycosis in almost all the seasons.

  8. Telomere attrition due to infection.

    Directory of Open Access Journals (Sweden)

    Petteri Ilmonen

    Full Text Available BACKGROUND: Telomeres--the terminal caps of chromosomes--become shorter as individuals age, and there is much interest in determining what causes telomere attrition since this process may play a role in biological aging. The leading hypothesis is that telomere attrition is due to inflammation, exposure to infectious agents, and other types of oxidative stress, which damage telomeres and impair their repair mechanisms. Several lines of evidence support this hypothesis, including observational findings that people exposed to infectious diseases have shorter telomeres. Experimental tests are still needed, however, to distinguish whether infectious diseases actually cause telomere attrition or whether telomere attrition increases susceptibility to infection. Experiments are also needed to determine whether telomere erosion reduces longevity. METHODOLOGY/PRINCIPAL FINDINGS: We experimentally tested whether repeated exposure to an infectious agent, Salmonella enterica, causes telomere attrition in wild-derived house mice (Mus musculus musculus. We repeatedly infected mice with a genetically diverse cocktail of five different S. enterica strains over seven months, and compared changes in telomere length with sham-infected sibling controls. We measured changes in telomere length of white blood cells (WBC after five infections using a real-time PCR method. Our results show that repeated Salmonella infections cause telomere attrition in WBCs, and particularly for males, which appeared less disease resistant than females. Interestingly, we also found that individuals having long WBC telomeres at early age were relatively disease resistant during later life. Finally, we found evidence that more rapid telomere attrition increases mortality risk, although this trend was not significant. CONCLUSIONS/SIGNIFICANCE: Our results indicate that infectious diseases can cause telomere attrition, and support the idea that telomere length could provide a molecular

  13. Mental retardation due to chromosomal translocation in an Iranian consanguineous family: report of three cases

    Directory of Open Access Journals (Sweden)

    Soudeh Ghafouri-Fard

    2017-02-01

    Full Text Available Background: Mental retardation is defined as impaired mental capacity and ability to comply with environmental and social conditions. Chromosomal abnormalities are the most important causes of mental retardation. Carriers of balanced chromosomal translocation are phenotypically normal, although they may be at risk of infertility, recurrent miscarriage or giving birth to mentally retarded children. These abnormalities are caused because chromosomes participated in the reciprocal translocations produce quadrivalents at meiosis. These quadrivalents segregate and lead to several different meiotic outcomes, just two of which are normal or balanced. Case Presentation: A consanguineous family with three mentally retarded daughters at the ages of 24, 18 and 10 years was referred to Comprehensive Medical Genetics Centre, Shiraz, Iran in 2015. Family history showed a case of unexplained infant death as well as a spontaneous abortion. Three survived siblings had hypotonia and severe developmental delay during infantile period. In addition, they suffer from primary amenorrhea. Two siblings have vesicoureteral reflux (VUR. Cytogenetic analysis of two patients showed 46,XX,t(6;12(q23;q22,der(9t(8;9(q24;p24 with partial monosomy of chromosome 9 and partial trisomy of 8q24 segment, while the other patient had 46,XX,der(12t(6;12(q23;q22 with partial monosomy of 12q22qter and partial trisomy of 6q23qter segment. Their mother had two balanced chromosomal translocations (46, XX, t(6,12(q21;q22, t(8,9(q24;p24. Conclusion: The above presented case is another example for the rare occurrence of double balanced chromosomal translocations in a phenotypically normal person. Although the most important causes of mental retardation in consanguineous marriages are autosomal recessive disorders, the role of chromosomal aberrations in mental retardation in these families must not be neglected. In other words, cytogenetic studies should be performed as a first line test in

  3. REVIEW ON LOCAL SCOUR DUE TO JETS

    Institute of Scientific and Technical Information of China (English)

    Arindam SARKAR; Subhasish DEY

    2004-01-01

    The safety of an apron of the energy dissipator is threatened by the large-scale scour in the downstream of the apron due to the erosive action of a horizontal jet issuing from a sluice opening. Also, large-scale deposition of the scoured sediments due to an impinging jet in a plunging pool type energy dissipator affects the passage of flow adversely in the downstream channels. Owing to the significant practical importance, the problem of local scour due to jets has been studied by many investigators. In this paper, a comprehensive review of the up-to-date investigations on local scour due to horizontal and impinging jets is presented including all possible aspects, such as scouring process, parameters affecting scour, time variation of scour,velocity distribution on the apron and within the scour hole, development of boundary layer thickness, bed shear stress, scour estimation formulas and protection works.

    1981-05-15

    The unusual radiographic pattern of bleb-like mounds on the surface of the colon mucosa, previously described as colonic urticaria, was seen in 3 patients in whom no allergic state was present. This urticaria-like pattern was due to colonic distention in all 3, and represented only submucosal edema on the gross and microscopic specimens. We hypothesize that this pattern is due to early changes of ischemia caused by colon distention.

    Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to neoplasm. Paraneoplastic syndromes may be the first or the most prominent manifestations of cancer. Wilm's tumor is the most frequent pediatric renal malignancy and usually presents with abdominal mass. Unusual presentations like acquired von Willebrand disease, sudden death due to pulmonary embolism and Cushing syndrome have been described in the literature. Cushing syndrome, as the presenting symptom of a malignant renal tumor in children, is a very rare entity. Few case reports are available in the literature exploring the option of preoperative chemotherapy as well as upfront nephrectomy. We report a rare case of paraneoplastic Cushing syndrome due to a Wilm's tumor. Based on gradual decrease of postoperative weight, blood pressure, serum adrenocorticotropic hormone, and plasma cortisol levels, along with histological confirmation of Wilm's tumor, paraneoplastic Cushing syndrome due to Wilm's tumor was confirmed.

  12. Gynecomastia: An ADR due to drug interaction

    Directory of Open Access Journals (Sweden)

    Aiman Umme

    2009-01-01

    Full Text Available Gynecomastia results from conditions that cause an imbalance of estrogenic and androgenic effects on the breast, resulting in an increased or unopposed estrogen action on breast tissue. Approximately 4 to 10% cases of gynecomastia are due to drugs. Both Digoxin and Furosemide are also reported to cause the same condition. Although, chances of gynecomastia could be more if these two drugs are coadministered, but no case report of this adverse effect is ever reported when both are prescribed concurrently. Here we report a case of gynecomastia suspected to have resulted from the coadministation of both the drugs. Probability of the adverse effect due to drug interaction was evaluated by DIPS, which suggests that the adverse drug reaction (ADR due to DI is "Possible."

    2016-01-01

    Acitretin is a synthetic oral retinoid that has been used for a number of dermatological diseases. Several side effects of acitretin have been reported such as teratogenicity, cheilitis, xerosis, dyslipidemia, and photosensitivity. Many drugs, mainly antibiotics and nonsteroidal anti-inflammatory drugs, can cause angioedema-urticaria. We present the case of angioedema-urticaria due to acitretin, confirmed by oral provocation test, in a 61-year-old man with psoriasis. To the best of our knowledge, only 1 case of angioedema due to oral acitretin has been reported in the literature so far. We report this case to draw attention that acitretin may cause angioedema-urticaria and to inform patients about this risk besides other side effects due to acitretin.

    The highest mortality due to cancer worldwide for both genders corresponds to lung cancer (1,179,000 deaths). In Mexico, the crude mortality rate due to lung cancer was of 5.01 per 10(5) inhabitants in 1979. The most important risk factor is smoking. The present study was aimed at analyzing the mortality due to lung cancer in Mexico, assessing data from each of the states constituting the Mexican Republic during the 1998-2004 period. Data were obtained from the National Institute of Statistics, Geography and Informatics (INEGI, for its initials in Spanish) corresponding to deaths due to lung cancer (1998-2004). We estimated the mean annual mortality rate (MAMR) for each of the 32 states of Mexico. We used the "World Population Standard". The MAMR was standardized according to age (ARS) direct method, and the standard error was determined by Poisson's approximation at a 95% confidence interval. To know the excess risk due to mortality, we calculated the standardized mortality ratios (SMRs) of ARS for each federal state, using the national rate as reference. In this period, 397,400 deaths due to malignant neoplasms were recorded, corresponding 45,578 (11.5%) to lung cancer; for men, 31,025 (68.1%) with MAMR of 8.9 and the respective ARS of 13.2 both x10(5) inhabitants. For women, results were 4553 (31.9%) deaths with MAMR of 4.1 and ARS of 5.4 both x10(5) inhabitants. The highest mortality rates due to lung cancer in both genders were observed in the north of Mexico, whereas for women this was observed in the central states. Although smoking is the main risk for lung cancer, there are other factors such as environmental pollution or exposure to toxicants that could be associated to this cancer. The years potentially lost due to lung cancer were 258,550 for men and 133,315 for women, with a total of 391,865 according to histopathology registry neoplasm malignant RHNM (1985-1995). Studies focused on the characterization and measurement of polluting agents would be a

    2009-01-01

    We report here a case of conjunctivitis in an immunocompetent patient due to Achromobacter xylosoxidans, which was associated with the use of rigid contact lenses. The bacteria were isolated from the scraped conjunctival swab as well as from the lens cleaning fluid. A. xylosoxidans is an opportunistic pathogen, especially in immunocompromised patients; however, in isolates of ocular infections, from immunocompetent patients, it may be confused with other gram-negative organisms, particularly Pseudomonas aeruginosa. Due to an increased resistance against different antimicrobial agents, A. xylosoxidans must be fully identified and differentiated from other gram-negative isolates from ocular infections.

    2010-04-01

    Jejunal diverticulosis is a rare malformation that is often asymptomatic. Complications might be similar to those occurring in large-bowel diverticula but also include a much more particular event: intestinal obstruction due to migration and impaction of enterolith formed inside diverticula. This is a very uncommon entity; diagnosis and management are thus often delayed. Mostly surgical exploration is necessary because obstruction symptoms are unresponsive to medical treatment. The authors report a new case of enterolith ileus in a 74-year-old man, due to jejunal diverticulosis, and its successful surgical management in emergency. Only 39 similar cases have ever been reported in the literature.

    Full Text Available The clinical presentation of perianal abscesses due to foreign bodies (FBs impacted in the anal canal mimics common causes of acute anal pain. The diagnosis can be established by digital rectal examination and/or proctoscopy, but may miss the presence of an FB. Incision and drainage of the abscess, along with removal of the FB, results in immediate pain relief and cure. Impacted FB must not be overlooked as an unusual cause of perianal abscess. One case of perianal abscesses due to FB impacted in the anal canal is reported.

    Prevotella bivia is associated with pelvic inflammatory disease. A 77-year-old man developed a rapidly growing chest wall abscess due to P. Bivia within days. He underwent surgical resection of the infected area; his postoperative course was un-eventful. This is the first case of chest wall abscess due to P. Bivia infection. Its correct diagnosis cannot be underestimated be-cause fulminam infections can occur in aged or immunocompromised patients if treated incorrectly. Prompt, appropriate surgical management, and antibiotic therapy affect treatment outcome.

    CERN Document Server

    Gupta, R C

    2010-01-01

    {\\it The universe is expanding} is known (through Galaxy observations) since 1929 through Hubble's discovery ($V = H D$). Recently in 1999, it is found (through Supernovae observations) that the universe is not simply expanding but is accelerating too. We, however, hardly know only $4\\%$ of the universe. The Wilkinson Microwave Anisotropy Probe (WMAP) satellite observational data suggest $73\\%$ content of the universe in the form of dark-energy, $23\\%$ in the form of non-baryonic dark-matter and the rest $4\\%$ in the form of the usual baryonic matter. The acceleration of the universe is ascribed to this dark-energy with bizarre properties (repulsive-gravity). The question is that whether Hubble's expansion is just due to the shock of big-bang & inflation or it is due to the repulsive-gravity of dark-energy? Now, it is believed to be due to dark-energy, say, by re-introducing the once-discarded cosmological-constant $\\Lambda$. In the present paper, it is shown that `the formula for acceleration due to dark...

    2014-01-01

    By its nature, the date that a baby is predicted to be born, or the due date, is uncertain. How women construct the uncertainty of their due dates may have implications for when and how women give birth. In the United States as many as 15% of births occur before 39 weeks because of elective inductions or cesarean sections, putting these babies at risk for increased medical problems after birth and later in life. This qualitative study employs a grounded theory approach to understand the decisions women make on how and when to give birth. Thirty-three women who were pregnant or had given birth within the past 2 years participated in key informant or small-group interviews. The results suggest that women interpret the uncertainty of their due dates as a reason to wait for birth and as a reason to start the process early; however, information about a baby's brain development in the final weeks of pregnancy may persuade women to remain pregnant longer. The uncertainties of due dates are analyzed using Babrow's problematic integration, which distinguishes between epistemological and ontological uncertainty. The results point to a third type of uncertainty, axiological uncertainty. Axiological uncertainty is rooted in the values and ethics of outcomes.

    Two cases of alopecia due to radiation of the scalp are presented in which it has been possible to achieve a technically and cosmetically satisfactory reconstruction by punch hair grafting. This does not mean that every case is suitable, but it does mean that those without contraindications should at least be given a try.

  15. Inherited peripheral neuropathies due to mitochondrial disorders.

    2014-05-01

    Mitochondrial disorders (MIDs) are frequently responsible for neuropathies with variable severity. Mitochondrial diseases causing peripheral neuropathies (PNP) may be due to mutations of mitochondrial DNA (mtDNA), as is the case in MERRF and MELAS syndromes, or to mutations of nuclear genes. Secondary abnormalities of mtDNA (such as multiple deletions of muscle mtDNA) may result from mitochondrial disorders due to mutations in nuclear genes involved in mtDNA maintenance. This is the case in several syndromes caused by impaired mtDNA maintenance, such as Sensory Ataxic Neuropathy, Dysarthria and Ophthalmoplegia (SANDO) due to recessive mutations in the POLG gene, which encodes the catalytic subunit of mtDNA polymerase (DNA polymerase gamma), or Mitochondrial Neuro-Gastro-Intestinal Encephalomyopathy (MNGIE), due to recessive mutations in the TYMP gene, which encodes thymidine phosphorylase. The last years have seen a growing list of evidence demonstrating that mitochondrial bioenergetics and dynamics might be dysfunctional in axonal Charcot-Marie-Tooth disease (CMT2), and these mechanisms might present a common link between dissimilar CMT2-causing genes.

  18. Timing shifts due to NIF beam repointing

    Energy Technology Data Exchange (ETDEWEB)

    Koch, J

    2007-08-15

    Repointing a NIF beam to hit a target position off target chamber center (TCC) will introduce a timing shift due to changes in the light pathlength. This shift could be important for target experiment requirements even for targets placed at TCC, since beam timing test shots will place beams up to 15 mm off TCC in order to spatially separate them on foil targets. In particular, timing errors due to beam repointing need to be considered against the 30 ps RMS timing requirement. Since the repointing process will keep the beam passing through a fixed point in the final optics assembly (the conversion crystal) by tip/tilt adjustments of two turning mirrors (LM5 and LM7), the problem naturally divides into two parts: Timing offsets past the conversion crystal due to target positioning changes, and timing offsets behind the fixed point on the conversion crystal due to turning mirror adjustments. Timing offsets past the conversion crystal can be significant, but are trivial to calculate exactly; however, an exact calculation of timing offsets behind the fixed point on the conversion crystal would require a three-dimensional optomechanical raytrace model to be developed for every beamline, and this would be difficult and expensive. In this memo, I estimate the magnitude of timing offsets due to pathlength changes behind the conversion crystal by analysis of a worst-case model. I conclude that these timing offsets are insignificant compared with the current allocation in the 30 ps RMS timing requirement, and that more detailed raytrace modeling of individual beams is not necessary.

    Full Text Available A fixed drug eruption (FDE is a cutaneous adverse drug reaction due to Type IV or delayed cell-mediated hypersensitivity. Antihistamines, which antagonize the action of histamine during an allergic reaction by blocking the H 1 histamine receptors, are used routinely for the treatment of various allergic disorders such as urticaria, eczemas, and also in itchy lesions of skin like scabies.Levocetirizine, an active (R-enantiomer of cetirizine, is a newer or second generation antihistamine, with more specific actions and fewer side effects, including cutaneous reactions. FDE due to levocetirizine as well as with cetirizine are rare. We report a case of levocetirizine induced FDE in a 49-year-old male patient with scabies. The patient had a history of cetirizine induced FDE in the past.

    Full Text Available Sciatica is defined as pain in the sciatic nerve distribution. The most common reason of sciatica is radiculopathy due to lumbar disc hernia. Other causes can be congenital, acquired, infectious, neoplastic, or inflammatory. The piriformis syndrome is another cause. The pain starts in an insidious manner when the cause of sciatica is an extraspinal tumor. It is intermittent at first but a constant and progressive pain that does not decrease with position or rest gradually develops in all patients. The possibility of an intraabdominal or pelvic mass should always be considered and the relevant tests requested when the cause of the sciatica cannot be explained. We present an 83-year-old male who presented with non-traumatic and non-vascular lumbosacral plexopathy due to a large hematoma in the left adductor muscle following the use of warfarin sodium.

    Tramadol is a common analgesic, widely prescribed because of its efficiency and safety. We report the case of a 7-year-old child admitted in cardiac intensive care unit for cardiogenic shock due to tramadol intoxication. Without any past history, the child was admitted at emergency room for generalised convulsion, followed by respiratory distress. Cardiogenic shock was suspected after clinical examination and chest X-ray and confirmed by transthoracic echocardiography showing low left ventricular ejection fraction (1 mg/L) and O-desmethyltramadol (>1.5 mg/L). Hemodynamic support by inotropic drug infusion and diuretics was necessary. Left ventricular function normalised after 2 days of treatment allowing drug infusion weaning. Cardiac magnetic resonance imaging performed 3 days after admission confirmed normal left ventricular ejection fraction and volumes without evidence of late gadolinium enhancement. Cardiogenic shock due to tramadol intoxication is rare but exists. Negative inotropic effect of high doses of tramadol has been suspected. Quick recovery is possible.

    The damping coefficient of capillary waves due to the evaporation-condensation process at the interface of the two phases of a fluid is evaluated. To highlight the mechanism of the effect of heat and mass transfer across the interface between regions of liquid and vapor, potential flow of incompressible fluids are assumed. Thus other mechanisms of damping are neglected. To fascilitate the analysis, the method of multiple-scale is employed in the analysis, even though the problem is linear.

    The dose due to {sup 40}K has been estimated. Potassium is one of the most abundant elements in nature, being approximately 2% of the Earth's crust. Potassium has three isotopes {sup 39}K, {sup 40}K and {sup 41}K, two are stable while {sup 40}K is radioactive with a half life of 1.2x10{sup 9} years; there is 0.0117% {sup 40}K-to-K ratio. Potassium plays an important role in plants, animals and humans growth and reproduction. Due to the fact that K is an essential element for humans, {sup 40}K is the most abundant radioisotope in human body. In order to keep good health conditions K must be intake at daily basis trough food and beverages, however when K in ingested above the requirements produce adverse health effects in persons with renal, cardiac and hypertension problems or suffering diabetes. In 89.3% {sup 40}K decays to {sup 40}C through {beta}-decay, in 10.3% decays through electronic capture and emitting 1.46 MeV {gamma}-ray. K is abundant in soil, construction materials, sand thus {gamma}-rays produced during {sup 40}K decay contribute to external dose. For K in the body practically all {sup 40}K decaying energy is absorbed by the body; thus {sup 40}K contributes to total dose in humans and it is important to evaluate its contribution. In this work a set of {sup 40}K sources were prepared using different amounts of KCl salt, a {gamma}-ray spectrometer with a NaI(Tl) was characterized to standardized the sources in order to evaluate the dose due to {sup 40}K. Using thermoluminescent dosemeters the dose due to {sup 40}K was measured and related to the amount of {sup 40}K {gamma}-ray activity. (Author)

    Summary Background Large leg ulcers (LLU) may complicate autoimmune diseases. They pose a therapeutic challenge and are often resistant to treatment. To report three cases of autoimmune diseases complicated with LLU. Case Report Case 1. A 55-year old woman presented with long-standing painful LLU due to mixed connective tissue disease (MCTD). Biopsy from the ulcer edge showed small vessel vasculitis. IV methylprednisolone (MethP) 1 G/day, prednisolone (PR) 1mg/kg, monthly IV cyclophosphamide (CYC), cyclosporine (CyA) 100mg/day, IVIG 125G, ciprofloxacin+IV Iloprost+enoxaparin+aspirin (AAVAA), hyperbaric oxygen therapy (HO), maggot debridement and autologous skin transplantation were performed and the LLU healed. Case 2. A 45-year old women with MCTD developed multiple LLU’s with non-specific inflammation by biopsy. MethP, PR, hydroxychloroquine (HCQ), azathioprine (AZA), CYC, IVIG, AAVAA failed. Treatment for underlying the LLU tibial osteomyelitis and addition of CyA was followed by the LLU healing. Case 3. A 20-year-old man with history of polyarteritis nodosa (PAN) developed painful LLU’s due to small vessel vasculitis (biopsy). MethP, PR 1 mg/kg, CYC, CyA 100 mg/d, AAVAA failed. MRSA sepsis and relapse of systemic PAN developed. IV vancomycin, followed by ciprofloxacin, monthly IVIG (150 g/for 5 days) and infliximab (5 mg/kg) were instituted and the LLU’s healed. Conclusions LLU are extremely resistant to therapy. Combined use of multiple medications and services are needed for healing of LLU due to autoimmune diseases. PMID:21169912

    Several countries experience a new epidemic of syphilis, mainly due to the changes in risk behaviors. Dermatologists play an important role in the diagnosis, since cutaneous manifestations are frequent during disease progression. We report a rare case of secondary syphilis with periungual involvement. Syphilis, especially in the secondary form, may present with different clinical features, affecting different organs, and mimicking many diseases. Although nail apparatus lesions are more common in the primary form of the disease, they may also be present in the secondary and tertiary forms. Therefore, a comprehensive knowledge of the diverse forms of syphilis presentation is important for an early diagnosis and timely treatment.

    A 46-year-old man developed intermittent headache, diplopia, and visual obscuration for two months. Funduscopic examination showed optic disk swelling in both eyes. Brain MRI exhibited hydrocephalus and leptomeningeal enhancement at the prepontine cistern, left cerebellopontine angle cistern and bilateral cerebral hemisphere, and hemosiderin deposition along the cerebellar folia. CSF analysis revealed an elevated opening pressure with xanthochromic appearance and small amount of red blood cells. Antibody titer against Toxocariasis using ELISA was elevated both in blood and CSF. Obstructive hydrocephalus and hemosiderin deposition in this case may result from the active inflammatory process due to CNS toxocariasis within the subarachnoid space.

    We study the motion of test particles in the metric of a localized and slowly rotating astronomical source, within the framework of linear gravitoelectromagnetism, grounded on a Post-Minkowskian approximation of general relativity. Special attention is paid to gravitational inductive effects due to time-varying gravitomagnetic fields. We show that, within the limits of the approximation mentioned above, there are cumulative effects on the orbit of the particles either for planetary sources or for binary systems. They turn out to be negligible.

    We reexamine inflation due to a constrained inflaton in the model of a complex scalar. Inflaton evolves along a spiral-like valley of special scalar potential in the scalar field space just like single field inflation. Sub-Planckian inflaton can induce sufficient e-foldings because of a long slow-roll path. In a special limit, the scalar spectral index and the tensor-to-scalar ratio has equivalent expressions to the inflation with monomial potential φ{sup n}. The favorable values for them could be obtained by varying parameters in the potential. This model could be embedded in a certain radiative neutrino mass model.

    The brainstem is said to be the generator of pathological startle responses due to reticular reflex myoclonus or hyperekplexia. A patient with facial weakness, nystagmus, and pyramidal tract signs had generalised reflex spasms in response to auditory, visual and tactile stimuli which clinically and neurophysiologically resembled hyperekplexia. The case is unusual because as well as hyperekplexia, the patient's initial presentation was with an equally rare manifestation of brainstem pathology—brainstem mediated trismus. The causes of brainstem trismus and exaggerated startle responses are discussed with respect to their underlying mechanisms.

    Cortical infarction presenting with pure dysarthria is rarely reported. Previous studies have reported pure dysarthria due to cortical stroke at the precentral gyrus or middle frontal gyrus. We report a 72-year-old man who developed pure dysarthria caused by an acute cortical infarction in the insular cortex. The role of the insula in language has been difficult to assess clinically because of the rarity of pure insular strokes. Our patient showed pure dysarthria without aphasia, indicating that pure dysarthria can be the sole manifestation of insular infarctions.

    Full Text Available A 43-year old patient presented to the emergency department with stretch, due to impossible deflation of the penile prosthesis, 4 years after successful implant. A CT-scan showed migration of the reservoir to the left rectus abdominis muscle. Refilling of the reservoir was inhibited by muscular compression, causing stretch. Removal and replacement of the reservoir was performed, after which the prosthesis was well-functioning again. Migration of the penile prosthesis reservoir is extremely rare but can cause several complications, such as stretch.

    Enterobacter cancerogenus (formerly known as CDC Enteric Group 19; synonym with Enterobacter taylorae) has rarely been associated with human infections, and little is known regarding the epidemiology and clinical significance of this organism. We describe a community-acquired pneumonia case in a 44-year-old female due to E. cancerogenus. Identification and antimicrobial susceptibility of the microorganism was performed by the automatized VITEK 2 Compact system (bioMerieux, France). The clinical case suggests that E. cancerogenus is a potentially pathogenic microorganism in determined circumstances; underlying diseases such as bronchial asthma, empiric antibiotic treatment, wounds, diagnostic, or therapeutic instruments.

    Full Text Available Erythema ab igne (EAI is characterized by localized areas of reticulated erythema and hyperpigmentation due to chronic and repeated exposure to infrared radiation. Taking a good history plays an important role in coming to the diagnosis of the disease condition; and at the same time, the particular cultural practices of a place determine its occurrence in the local masses. Herein we report the case of a young lady in her early thirties who presented to us with a dusky hyperpigmentation over her right arm and leg. Her detailed history and cutaneous examination led to the diagnosis of erythema ab igne.

    2013-01-01

    We performed a retrospective review of patients who presented with delayed dystopia as a consequence of an orbital roof defect due to fractures and nontraumatic causes to search for a correlation between orbital roof defect size and surgical indications for the treatment thereof. Retrospective analyses were performed in 7 patients, all of whom presented with delayed dystopia due to orbital roof defects, between January 2001 and June 2011. The causes of orbital roof defects were displaced orbital roof fractures (5 cases), tumor (1 case), and congenital sphenoid dysplasia (1 case). All 7 patients had initially been treated conservatively and later presented with significant dystopia. The sizes of the defects were calculated on computed tomographic scans. Among the 7 patients, aspiration of cerebrospinal fluid, which caused ocular symptoms, in 1 patient with minimal displaced orbital roof and reconstruction with calvarial bone, titanium micromesh, or Medpor in 6 other patients were performed. The minimal size of the orbital roof in patients who underwent orbital roof reconstruction was 1.2 cm (defect height) x 1.0 cm (defect length), 0.94 cm(2). For all patients with orbital dystopia, displacement of the globe was corrected without any complications, regardless of whether the patient was evaluated grossly or by radiology. In this retrospective study, continuous monitoring of clinical signs and active surgical management should be considered for cases in which an orbital roof defect is detected, even if no definite symptoms are noted, to prevent delayed sequelae.

    Full Text Available Background: Cheilitis is a common problem of unknown etiology. A possible cause of cheilitis is contact allergy. Drugs, lipsticks, sunblock and toothpaste are the most common implicated allergens. Allergic contact cheilitis is a chronic superficial inflammatory disorder of the vermilion borders characterized by desquamation due to delayed-type hypersensitivity reaction. Purpose: We report a management of Allergic contact cheilitis due to lipsticks. Case: A 21-year-old woman had a history of atopic allergy to eggs, milk, and chicken presented with sore, dry, fissured, scaled and sometimes bleeding lip, over a 3-month period after application of a lipstick. Her symptoms persisted despite treatments with hydrocortisone cream. The patient provided a detailed history and underwent physical examination and patch tests to cosmetic components and patch test to her own lipstick. The patient had strongly-positive result to the tested lipstick. A diagnosis of allergic contact cheilitis was made based on the history and clinical findings. Case management: Patient was advised to avoid wearing lipstick. To relieve symptoms, treatment was initiated with combined topical corticosteroid, antibiotic, and moisturizer. Conclusion: Contact allergy patients should be tested for both cosmetic component series and their own lipsticks to exclude exfolliative cheilitis, infection, or light actinic cheilitis as causal agents.

    Thoracic infections due to Trichomonas species often go unrecognised as they are seldom described in the literature. We describe a case that, to our knowledge, is the first reported case of empyema caused by this organism. A 59 year old man with metastatic adenocarcinoma of the lung developed a right pyopneumothorax following treatment with corticosteroids and radiotherapy. The pleural fluid was purulent and fetid, and contained large numbers of Trichomonas tenax amongst a mixed bacterial flora. Pleural drainage and antibiotic therapy with metronidazole, ciprofloxacin and gentalline were instituted immediately, but the patient died 4 days later. Trichomonas tenax is part of the normal oral floral and may on occasions colonize the airways. It can thus become involved during aspiration pneumonia or cause pleural infection following the rupture of a pulmonary abscess. Such infection tends to be associated with concurrent respiratory pathology or with immunodepression. The significance Trichomonas tenax when found in the airways is unclear and their pathogenic role is discussed.

    The RFP EXTRAP T2R is equipped with a comprehensive active feedback system (128 active saddle coils in the full-coverage array) and active control of both resonant and non-resonant MHD modes has been demonstrated. The feedback algorithms, based on modern control methodology such as reference mode tracking (both amplitude and phase), are a useful tool to improve the ``state of the art'' of the MHD mode control. But this tool can be used also to improve the understanding and the characterization of other phenomena such as the ELM mitigation with a resonant magnetic perturbation or the plasma viscosity. The present work studies plasma and mode braking due to static RMPs. Results show that a static RMP produces a global braking of the flow profile. The study of the effect of RMPs characterized by different helicities will also give information on the plasma viscosity profile. Experimental results are finally compared to theoretical models.

  11. Acute renal failure due to rhabdomyolyisis

    Directory of Open Access Journals (Sweden)

    Nieto-Ríos, John Fredy

    2016-04-01

    Full Text Available Acute renal failure is a frequent cause of morbidity and mortality in emergency, hospitalization and critical care services. In 15 % of cases it is due to rhabdomyolysis, in which there is breakdown of skeletal muscle with massive necrosis and leakage of muscle cell contents into the circulation. It has many different etiologies. The rhabdomyolysis-induced acute kidney injury results from the combination of several mechanisms, including tubular obstruction, vasoconstriction and oxidative stress. The most important therapeutic measures are: Aggressive repletion of fluids, forced diuresis and avoidance of exposure to nephrotoxic substances. In cases of severe uremia, metabolic acidosis, hiperkalemia or fluid overload it is necessary to start renal replacement therapy. As a rule, kidney function is completely recovered, but these patients have higher risk of future chronic kidney disease.

    2011-09-01

    Mycobacterium fortuitum, a rapidly growing non-tuberculous atypical mycobacterium, is commonly found in soil and water. This organism generally causes skin, bone, and soft tissue infections following local trauma or surgical procedures, and in immunodeficient patients. The case reported here is, to our knowledge, the first published report of M. fortuitum nasal infection. The authors report the case of a 3-year-old girl with intranasal tumour-like swelling associated with cervical lymph nodes due to M. fortuitum infection. A combination of radical surgical debridement and prolonged therapy with several antimicrobial agents was required to completely eradicate the infection. This case report indicates that non-tuberculous mycobacterial infections should be considered after failure of conventional antibiotic therapy or when classical microbiological tests fail to identify the pathogen responsible for sinonasal and cervical infections.

    2005-01-01

    The purpose of this paper was to investigate the occurrence of maltreatment in children abused by alcohol users. Authors looked at the records of children hospitalized from 2000 to 2003 at the Children Hospital "Dr. Ovidio Aliga Uria". Findings showed that among the total of hospitalizations, 0.62% were due to maltreatment. Considering them, 57.9% involved alcohol users. Approximately 12.9% of them died as a consequence of brain trauma. The characterization of the aggressors showed that they are abusive drinkers with no dependence; with age varying from 20 to 30 years, are members of the children's family; finished primary school, do not have a job and are drug users. Although the low percentage of cases, there is a need to take care of this situation aiming at protecting the children and respecting their rights as well as at providing care to the adult that also experiences stressing conditions.

    Full Text Available Fixed drug eruption is a common type of drug eruption seen in dermatology OPD’s. Usually it is seen with sulphonamides, salicylates, tetracyclines, oxyphenbutazones, dapsone, barbiturates, phenolphthalein, morphine, codeine, quinine, phenacetin, erythromycin, griseofulvin, mebendazole etc. We hereby report a case of fixed drug eruption due to single dose of oral paracetamol in an otherwise healthy male after one hour of consuming it. A provisional diagnosis of Paracetamol induced fixed drug eruption was made. Paracetamol was stopped and patient advised never to take Paracetamol in future. Patient was managed with prednisolone 10mg /day, cetirizine 10 mg/day, and amoxicillin 500 mg twice a day and mometasone + fusidic acid cream to be applied over the lesions.

    2015-01-01

    Full Text Available Vast majority of bowel obstruction is due to postoperative adhesions, malignancy, intestinal inflammatory disease, and hernias; however, knowledge of other uncommon causes is critical to establish a prompt treatment and decrease mortality. Xanthomatosis is produced by accumulation of cholesterol-rich foamy macrophages. Intestinal xanthomatosis is an uncommon nonneoplastic lesion that may cause small bowel obstruction and several cases have been reported in the English literature as obstruction in the jejunum. We report a case of small intestinal xanthomatosis occurring in a 51-year-old female who presented with one day of copious vomiting and intermittent abdominal pain. Radiologic images revealed jejunal loop thickening and inflammatory changes suggestive of foreign body obstruction, diagnostic laparoscopy found two strictures at the jejunum, and a pathologic examination confirmed a segmental small bowel xanthomatosis. This case illustrates that obstruction even without predisposing factors such as hyperlipidemia or lymphoproliferative disorders.

    2016-01-01

    The hypomyelinating leukodystrophies (HMLs) encompass the X-linked Pelizaeus-Merzbacher disease (PMD) caused by PLP1 mutations and known as the classical form of HML as well as Pelizaeus-Merzbacher-like disease (PMLD) (Online Mendelian Inheritance in Man [OMIM] 608804 and OMIM 260600) due to GJC2...... mutations. In addition, mutations in at least 10 other genes are known to cause HMLs. In 2008, an Israeli family with clinical and neuroimaging findings similar to those found in PMD was reported. The patients were found to have a homozygous missense mutation in HSPD1, encoding the mitochondrial heat......-shock protein 60 (Hsp60), and the disorder was defined as the autosomal recessive mitochondrial Hsp60 chaperonopathy (MitCHAP-60) disease. We here report the first case of this severe neurodegenerative disease since it was first described. Given the fact that the families carried the same mutation our patient...

    2015-01-01

    Imatinib mesylate is a selective tyrosinase kinase inhibitor which has revolutionized the treatment of chronic myeloid leukemia. It is also used in gastrointestinal stromal tumors and dermatofibrosarcoma protruberans. Cutaneous adverse reactions are the most common nonhematological side effects secondary to imatinib. Nonlichenoid reactions are common, while lichenoid reactions are rare. We report a case of lichenoid drug eruption due to imatinib. As the indications and use of imatinib are increasing, the incidences of adverse effects, including cutaneous ones, are likely to increase. Some of the reactions may be severe enough to warrant discontinuation of the drug. The physicians should be aware of this morphological entity, which is usually benign and does not warrant withdrawal of the drug.

    2014-01-01

    While the seismic effects of wave-induced fluid flow due to mesoscopic heterogeneities have been studied for several decades, the role played by these types of heterogeneities on seismoelectric phenomena is largely unexplored. To address this issue, we have developed a novel methodological framework which allows for the coupling of wave-induced fluid flow, as inferred through numerical oscillatory compressibility tests, with the pertinent seismoelectric conversion mechanisms. Simulating the corresponding response of a water-saturated sandstone sample containing mesoscopic fractures, we demonstrate for the first time that these kinds of heterogeneities can produce measurable seismoelectric signals under typical laboratory conditions. Given that this phenomenon is sensitive to key hydraulic and mechanical properties, we expect that the results of this pilot study will stimulate further exploration on this topic in several domains of the Earth, environmental, and engineering sciences.

  19. Observations on brucellosis due to Brucella melitensis.

    SPINK, W W

    1953-01-01

    A special study was made of the problem of brucellosis due to Brucella melitensis in visits to Mexico City in 1948, to the FAO/WHO Brucellosis Centres at Montpellier (France), Florence (Italy), and Rijeka (Yugoslavia) in 1951, and to Spain in 1952. Br. melitensis infection in human beings causes more severe illness than Br. abortus infection. It develops primarily in rural communities living in close contact with goats and sheep; cattle and swine may also harbour the infection.In diagnosis, the agglutination test has proved the most satisfactory procedure; testing would be more uniformly reliable if a single antigen were used. Lack of funds and technical assistance have in many instances limited the bacteriological studies upon which a more definitive diagnosis of brucellosis depends.Antibiotics, Brucella vaccines, and colloidal preparations of gold and silver-used separately and in combination-have proved of varying therapeutic value, although response to antibiotics is less favourable than in cases of Br. abortus infection.While the drastic measures-involving the slaughter of about 10,000 sheep-taken in Slovenia, Yugoslavia, in the late 1940's, against an outbreak of brucellosis, is an inspiring example of how the disease can be eradicated, the removal of all diseased animals is rarely feasible economically. It is hoped that future research will reveal a practicable alternative in the immunization of sheep and goats against the disease.

    Full Text Available A two year-old male child presented with cutis marmorata congenita universalis, brittle hair, mild mental retardation, and finger spasms. Biochemical findings include increased levels of homocysteine in the blood-106.62 µmol/L (normal levels: 5.90-16µmol/L. Biochemical tests such as the silver nitroprusside and nitroprusside tests were positive suggesting homocystinuria. The patient was treated with oral pyridoxine therapy for three months. The child responded well to this therapy and the muscle spasms as well as skin manifestations such as cutis marmorata subsided. The treatment is being continued; the case is reported here because of its rarity. Homocysteinuria arising due to cystathionine beta-synthase (CBS deficiency is an autosomal recessive disorder of methionine metabolism that produces increased levels of urinary homocysteine and methionine It manifests itself in vascular, central nervous system, cutaneous, and connective tissue disturbances and phenotypically resembles Marfan′s syndrome. Skin manifestations include malar flush, thin hair, and cutis reticulata / marmorata.

    2010-01-01

    Full Text Available Research on nighttime sleep disturbance due to community noise sources, particularly from exposure to aircraft noise, has been conducted for over a half decade. However, there are still no national environmental noise policies (i.e., laws and regulations promulgated which prescribe a specific criterion for an exposure limit which is regulatory in nature. In the U.S., the new American National Standards Institute (ANSI Noise Standard, ANSI S12.9-2008/Part 6, Quantities and Procedures for Description and Measurement of Environmental Sound - Part 6: Methods for Estimation of Awakenings Associated with Outdoor Noise Events Heard in Homes, does provide the currently recommended exposure-response relationship used in the U.S. In Europe, there has also been significant laboratory and field research on sleep disturbance, although the U.S. and European research publications often use different research methodologies, different noise metrics and different meta-analysis techniques. The current article will provide a brief overview of sleep disturbance research internationally to document the similarities and differences between the various research approaches and research results.

  2. Haemoptysis due to pulmonary venous stenosis

    2014-06-01

    Full Text Available Haemoptysis is a potentially life-threatening condition with the need for prompt diagnosis. In about 10–20% of all cases the bleeding source remains unexplained with the standard diagnostic approach. The aim of this article is to show the necessity of widening the diagnostic approach to haemoptysis with consideration of pulmonary venous stenosis as a possible cause of even severe haemoptysis and haemoptoe. A review of the literature was performed using the Medline/PubMed database with the terms: “pulmonary venous stenosis”, “pulmonary venous infarction” and “haemoptysis”. Further references from the case reports were considered. 58 case reports and case collections about patients with haemoptysis due to pulmonary venous stenosis were detected. This review gives an overview about the case reports and discusses the underlying pathophysiology and the pros and cons of different imaging techniques for the detection of pulmonary venous stenosis. Several conditions predispose to the obstruction of the mediastinal pulmonary veins. Clinical findings are unspecific and may be misleading. Pulmonary venous stenosis can be detected using several imaging techniques, yet three-dimensional magnetic resonance-angiography and three-dimensional contrast-enhanced computed tomography are the most appropriate. Pulmonary venous stenosis should be considered in patients with haemoptysis.

    This study assessed current health risks due to occupational exposure to coffee dust. We performed a cross-sectional study in a coffee haulage company (n = 24), a coffee silo (n = 19), and a decaffeinating company (n = 17). Cross-shift and cross-week case histories of these employees as well as lung function values were recorded. During the handling of green coffee, measurements of airborne dust were conducted. The employees in these workplaces were mainly affected by erythematous and rhinoconjunctival symptoms. They occurred especially in subjects exposed to a high dust load (> 10 mg of inhalable dust per cubic meter of air; n = 28) [Pearson chi(2) test, p = 0.020 and p = 0.023]. IgE antibodies to green coffee and castor beans were detected in 3 workers and 10 workers, respectively. The majority of them (two employees and six employees, respectively) had shown respiratory symptoms during the past 12 months. The preshift lung function values were below average but were not dependent on the level of the inhalable coffee dust exposure. Employees with a coffee dust load > 10 mg/m(3) of air showed higher unspecific bronchial responsiveness more frequently than those with lower exposures. During the transshipment (especially during unloading) of green coffee, a high and clinically relevant exposure to irritative and sensitizing dust occurs. Therefore, efforts to reduce these dust exposures are generally recommended.

    Full Text Available Brucella infection is a systemic disease. It rarely causes local infections like hepatitis in gastrointestinal system. In this article we would like to present an acute hepatitis case related to brucella infection that followed up in our clinic. A male, 30 year-old patient hospitalized due to common muscle pain, high fever and vomiting. During the physical examination the patient’s skin, scleras and mucosal membranes were icteric, the liver was 2-3 cm palpable and tender. Laboratory findings were as follows: AST:1190 U/L; ALT:715 U/L; GGT:961 U/L; ALP:369 U/L; total bilirubin:4.6 mg/dL; direct bilirubin:2.1 mg/dL. Viral markers were found to be negative. We started treatment with streptomicine and doxicycline since, the patient’s standard brucella tube agglutination test was positive (1/60 and brucella spp produced in his blood culture. From the second day of the treatment, we started to get clinical response. On the 17th day of the treatment, he discharged from the hospital because ALT, AST and bilirubine level were found normal and his treatment was completed to the 8 weeks. Brucella is continuing to be an important health problem especially who live in surrounding countryside and have to keep in mind in the differential diagnosis of the acute hepatitis.

    Single-phase and two-phase geothermal reservoirs are currently being exploited for power production in Italy, Mexico, New Zealand, the United States, and elsewhere. Vertical ground displacements of up to 4.5 m and horizontal ground displacements of up to 0.5 m have been observed at Wairakei, New Zealand, that are clearly attributable to the resource exploitation. Similarly, vertical displacements of about 0.13 m have been recorded at The Geysers, California. No significant ground displacements that are attributable to large-scale fluid production have been observed at Larderello, Italy, and Cerro Prieto, Mexico. In this paper, observations show that subsidence due to geothermal fluid production is characterized by such features as an offset of the subsidence bowl from the main area of production, time-lag between production and subsidence, and nonlinear stress-strain relationships. Several plausible conceptual models, of varying degrees of sophistication, have been proposed to explain the observed features. At present, relatively more is known about the physical mechanisms that govern subsidence than the relevant thermal mechanisms. Finally, although attempts have been made to simulate observed geothermal subsidence, the modeling efforts have been seriously limited by a lack of relevant field data needed to sufficiently characterize the complex field system.

  6. Dermatoses due to Indian cultural practices.

    Gupta, Divya; Thappa, Devinder Mohan

    2015-01-01

    A wide prevalence of socio-religious and cultural practices in the Asian subcontinent often leads to multitude of skin diseases which may be missed by the dermatologists because of a lack of awareness. 'Henna' use causes IgE-mediated hypersensitivity reactions and contact dermatitis. 'Kumkum' application can result in pigmented contact dermatitis and lichen planus pigmentosus. Sticker 'bindis' and 'alta' induce contact leukoderma. Irritant and allergic contact dermatitis occurs after playing with 'Holi' colors. Threading and drawstring dermatitis lead to koebnerization of pre-existing dermatoses, infections and even squamous cell carcinoma of skin. Mild irritant reactions and contact sensitization occur secondary to balm and hair oil use. 'Mudichood' represents the comedogenic effect of hair oils combined with occlusion and humidity. Aromatherapy oils can cause contact dermatitis and photosensitive reactions. Heavy metal and steroid toxicity along with severe cutaneous adverse effects like erythroderma can occur as a consequent to the use of alternative medicines. Squamous cell carcinoma due to chronic heat exposure from the heating device "kangri" is seen in Kashmiris. Prayer nodules in Muslims and traction alopecia in Sikhs illustrate how religious practices can negatively affect the skin. With increasing globalization and migration, the practice of indigenous customs and traditions is no longer limited to regional territories, making it imperative for the dermatologists to be acquainted with the cutaneous side effects they can cause.

  7. Jejunal Diverticular Perforation due to Enterolith

    2011-08-01

    Full Text Available Jejunal diverticulosis is a rare entity with variable clinical and anatomical presentations. Although there is no consensus on the management of asymptomatic jejunal diverticular disease, some complications are potentially life-threatening and require early surgical treatment. Small bowel perforation secondary to jejunal diverticulitis by enteroliths is rare. The aim of this study was to report a case of small intestinal perforation caused by a large jejunal enterolith. An 86-year-old woman was admitted with signs of diffuse peritonitis. After initial fluid recovery the patient underwent emergency laparotomy. The surgery showed that she had small bowel diverticular disease, mainly localized in the proximal jejunum. The peritonitis was due to intestinal perforation caused by an enterolith 12 cm in length, localized inside one of these diverticula. The intestinal segment containing the perforated diverticulum with the enterolith was removed and an end-to-end anastomosis was done to reconstruct the intestinal transit. The patient recovered well and was discharged from hospital on the 5th postoperative day. There were no signs of abdominal pain 1 year after the surgical procedure. Although jejunal diverticular disease with its complications, such as formation of enteroliths, is difficult to suspect in patients with peritonitis, it should be considered as a possible source of abdominal infection in the elderly patient when more common diagnoses have been excluded.

    The author reports a rare case of Horner syndrome in a patient who resulted from stenosis of the vertebral artery after blunt trauma. A 31-year-old man was transferred to our department for evaluation of left medial orbital wall and nasal bone fractures. Five days ago, he was hospitalized due to multiple second to fourth rib fractures of the right chest following blunt trauma of the face, neck, and chest. Surgery was performed. Ten days later, he complained of drooping of the right eyelid. Physical examination revealed a discrete miosis and ptosis with normal levator function in the right eye. A workup for Horner syndrome was performed. Magnetic resonance angiography of the head and neck revealed a stenosis of the distal part of the right vertebral artery without the abnormality of carotid artery. He wore a cervical collar and underwent anticoagulation. However, Horner syndrome was not resolved over the next 12 months. Acute traumatic Horner syndrome may be associated with vertebral artery dissection in which the possibility of life-threatening injury can be masked.

  9. Decreased pain sensitivity due to trimethylbenzene exposure ...

    Science.gov (United States)

    Traditionally, human health risk assessments have relied on qualitative approaches for hazard identification, often using the Hill criteria and weight of evidence determinations to integrate data from multiple studies. Recently, the National Research Council has recommended the development of quantitative approaches for evidence integration, including the application of meta-analyses. The following hazard identification case study applies qualitative as well as meta-analytic approaches to trimethylbenzene (TMB) isomers exposure and the potential neurotoxic effects on pain sensitivity. In the meta-analytic approach, a pooled effect size is calculated, after consideration of multiple confounding factors, in order to determine whether the entire database under consideration indicates that TMBs are likely to be a neurotoxic hazard. The pain sensitivity studies included in the present analyses initially seem discordant in their results: effects on pain sensitivity are seen immediately after termination of exposure, appear to resolve 24 hours after exposure, and then reappear 50 days later following foot-shock. Qualitative consideration of toxicological and toxicokinetic characteristics of the TMB isomers suggests that the observed differences between studies are due to testing time and can be explained through a complete consideration of the underlying biology of the effect and the nervous system as a whole. Meta-analyses and –regressions support this conclus

    2011-12-01

    Intrathecal spinal catheters (lumbar drains) are indicated for several medical and surgical conditions. In neurosurgical procedures, they are used to reduce intracranial and intrathecal pressures by diverting CSF. They have also been placed for therapeutic access to administer drugs, and more recently, vascular surgeons have used them to improve spinal cord perfusion during the treatment of thoracic aortic aneurysms. Insertion of these lumbar drains is not without attendant complications. One complication is the shearing of the distal end of the catheter with a resultant retained fragment. The authors report the case of a 65-year-old man who presented with a subarachnoid hemorrhage due to the migration of a retained lumbar drain that sheared off during its removal. To the best of the authors' knowledge, this is the first case of rostral migration of a retained intrathecal catheter causing subarachnoid hemorrhage. The authors review the literature on retained intrathecal spinal catheters, and their findings support either early removal of easily accessible catheters or close monitoring with serial imaging.

  11. Hospitalisations due to falls in older persons.

    LENUS (Irish Health Repository)

    Carey, D

    2005-06-01

    This paper describes hospitalisations due to falls among people aged 65 years and over resident in the Eastern Region of Ireland. Of the 2,029 hospitalisations recorded for 2002, 78% were female and 68% were aged 75 years and over. Fractures accounted for 1,697 or 84% of cases with nearly half of them (841) sustained to the hip. Females were more likely to have a limb fracture whereas males were more likely to have a head injury. The total inpatient costs of the 2,029 hospitalisations were estimated at 10.6 million euros. Hip fractures were the costliest injuries as they accounted for 7.4 million euros (70%) of inpatient costs. There are also substantial additional costs implications for hip fractures as they constituted the majority (56%) of cases transferred to nursing\\/convalescent homes or long-stay health facilities. In keeping with an ageing population, the problem of injuries in older people is likely to increase over time and as falls are the dominant cause of those injuries, all acute and long-stay health facilities need to develop and implement fall prevention strategies for older people.

    2012-04-01

    Full Text Available Introduction: Pneumonia is one of the most common infections during childhood. In children with recurrent bacterial pneumonia complete evaluation for underlying factors is necessary. The most common underlying diseases include: antibody deficiencies , cystic fibrosis , tracheoesophageal fistula and increased pulmonary blood flow. Vascular ring and its pressure effect is a less common cause of stridor and recurrent pneumonia. Congenital abnormalities in aortic arch and main branches which form vascular ring around esophagus and trachea with variable pressure effect cause respiratory symptoms such as stridor , wheezing and recurrent pneumoniaCase Report: A 2 year old boy was admitted in our hospital with respiratory distress and cough . Chest x-Ray demonstrated right lobar pneumonia. He had history of stridor and wheezing from neonatal period and hospitalization due to pneumonia for four times. The patient received appropriate antibiotics. Despite fever and respiratory distress improvement, wheezing continued. Review of his medical documents showed fixed pressure effect on posterior aspect of esophagus in barium swallow. In CT angiography we confirmed double aortic arch.Conclusion: Double aortic arch is one of the causes of persistant respiratory symptom and recurrent pneumonia in children for which fluoroscopic barium swallow is the first non-invasive diagnostic method.(Sci J Hamadan Univ Med Sci 2012;19(1:70-74

    2014-10-01

    Dengue infection is an important arboviral infection in southeast Asia, especially in India. Neurological manifestations of dengue are increasingly recognized. We report an ischemic stroke due to dengue vasculitis in an 8-year-old child. We present a girl with a short febrile illness followed by episodic severe headache, with gradually progressive hemiparesis and visual impairment. Her brain magnetic resonance imaging revealed multiple infarctions in the anterior and posterior circulation. The magnetic resonance angiogram revealed irregular narrowing of bilateral middle cerebral arteries, right anterior cerebral artery, left posterior cerebral, and bilateral vertebral arteries suggestive of vasculitis. Her dengue serology was strongly positive for immunoglobulin M with 68.9 panbio units. The rest of the evaluation for pediatric stroke was unremarkable. She was treated with intravenous followed by oral corticosteroids and recovered totally with resolution of vasculitis on magnetic resonance angiogram over the next 3 months. This child illustrates possible immune-mediated vasculitis caused by dengue infection which is rather a rare presentation in a child who subsequently recovered well. One should consider dengue in childhood strokes in endemic regions. Copyright © 2014 Elsevier Inc. All rights reserved.

    Pulmonary hypertension (PH), a common complication of left heart diseases (LHD), negatively impacts symptoms, exercise capacity, and outcome. Although the true prevalence of PH-LHD is unknown, a subset of patients might present significant PH that cannot be explained by a passive increase in left-sided filling pressures. The term "out-of-proportion" PH has been used to identify that population without a clear definition, which has been found less than ideal and created confusion. We propose a change in terminology and a new definition of PH due to LHD. We suggest to abandon "out-of-proportion" PH and to distinguish "isolated post-capillary PH" from "post-capillary PH with a pre-capillary component" on the basis of the pressure difference between diastolic pulmonary artery pressure and pulmonary artery wedge pressure. Although there is no validated treatment for PH-LHD, we provide insights into management and discuss completed and randomized trials in this condition. Finally, we provide recommendations for future clinical trials to establish safety and efficacy of novel compounds to target this area of unmet medical need.

    Full Text Available Objectives Discuss neuropsychiatric aspects and differential diagnosis of catatonic syndrome secondary to systemic lupus erythematosus (SLE in a pediatric patient. Methods Single case report. Result A 13-year-old male, after two months diagnosed with SLE, started to present psychotic symptoms (behavioral changes, hallucinations and delusions that evolved into intense catatonia. During hospitalization, neuroimaging, biochemical and serological tests for differential diagnosis with metabolic encephalopathy, neurological tumors and neuroinfections, among other tests, were performed. The possibility of neuroleptic malignant syndrome, steroid-induced psychosis and catatonia was also evaluated. A complete reversal of catatonia was achieved after using benzodiazepines in high doses, associated with immunosuppressive therapy for lupus, which speaks in favor of catatonia secondary to autoimmune encephalitis due to lupus. Conclusion Although catatonia rarely is the initial clinical presentation of SLE, the delay in recognizing the syndrome can be risky, having a negative impact on prognosis. Benzodiazepines have an important role in the catatonia resolution, especially when associated with parallel specific organic base cause treatment. The use of neuroleptics should be avoided for the duration of the catatonic syndrome as it may cause clinical deterioration.

    Alpha particles diffusion due to charge changes in a magnetized plasma is studied. Analytical calculations and numerical simulations are employed to show that this process can be very important in the pedestal-edge-SOL regions. This is the first study that presents clear evidence of the importance of atomic processes on the diffusion of alpha particles. A simple 1D model that includes inelastic collisions with plasma species, “cold” neutrals, and partially ionized species was employed. The code, which follows the exact particle orbits and includes the effect of inelastic collisions via a Monte Carlo type random process, runs on a graphic processor unit (GPU). The analytical and numerical results show excellent agreement when a uniform background (plasma and cold species) is assumed. The simulations also show that the gradients in the density of the plasma and cold species, which are large and opposite in the edge region, produce an inward flux of alpha particles. Calculations of the alpha particles flux reaching the walls or divertor plates should include these processes.

    A wide prevalence of socio-religious and cultural practices in the Asian subcontinent often leads to multitude of skin diseases which may be missed by the dermatologists because of a lack of awareness. ‘Henna’ use causes IgE-mediated hypersensitivity reactions and contact dermatitis. ‘Kumkum’ application can result in pigmented contact dermatitis and lichen planus pigmentosus. Sticker ‘bindis’ and ‘alta’ induce contact leukoderma. Irritant and allergic contact dermatitis occurs after playing with ‘Holi’ colors. Threading and drawstring dermatitis lead to koebnerization of pre-existing dermatoses, infections and even squamous cell carcinoma of skin. Mild irritant reactions and contact sensitization occur secondary to balm and hair oil use. ‘Mudichood’ represents the comedogenic effect of hair oils combined with occlusion and humidity. Aromatherapy oils can cause contact dermatitis and photosensitive reactions. Heavy metal and steroid toxicity along with severe cutaneous adverse effects like erythroderma can occur as a consequent to the use of alternative medicines. Squamous cell carcinoma due to chronic heat exposure from the heating device “kangri” is seen in Kashmiris. Prayer nodules in Muslims and traction alopecia in Sikhs illustrate how religious practices can negatively affect the skin. With increasing globalization and migration, the practice of indigenous customs and traditions is no longer limited to regional territories, making it imperative for the dermatologists to be acquainted with the cutaneous side effects they can cause.

    Clostridium septicum is an unusual anaerobic, gram-positive, gas-producing bacillus, which has been identified as a cause of fulminant rapidly fatal infection in humans. Infection with C. septicum usually occurs in patients with cancer, patients receiving immunosuppressive chemotherapy, or patients with a nonmalignant hematological disorder such as hemolytic uremic syndrome. C. septicum infection most commonly involves the abdomen, and a recent review article has identified 164 cases in the medical literature describing the abdominal findings in this disease. Intracranial manifestation of C. septicum infection are less common and include meningitis, cerebritis, abscess formation and pneumocephalus. There have been only 12 documented cases in the English literature describing central nervous system lesions associated with C. septicum. We present a case report of a 56-year-old man in whom septicemia due to C. septicum developed as a complication of Crohn's disease. To our knowledge, there has never been a previous report of C. septicum sepsis related to underlying Crohn's disease. Our case is also remarkable in that an intracerebral gas collection developed at the site of a mycotic infarct related to C. septicum bacteremia, Intracranial, intraparenchymal gas formation related to anaerobic infection is extremely rare; to our knowledge, this radiological finding related to C. septicum sepsis has been described in only 1 previous case report in the medical literature. We also describe the intra-abdominal manifestations of C. septicum sepsis that occurred in this patient as well as the associated radiographic and pathologic findings. (author)

    Full Text Available Out of a total of 1147 patients on antihypertensive drugs, 23 (2.04% developed adverse cutaneous drug reactions (ACDR. The commonest antihypertensive drug group causing ACDR was beta-blockers of which atenolol was the commonest culprit. The second most common group was calcium channel blockers with amlodipine as the commonest offender. The most common patterns of ACDR observed included urticaria followed by lichenoid drug eruption (LDE. We noted 2 new patterns of reactions; (i one patient developed brownish blue pigmentation of nails while on atenolol for 3 years, which resolved in 4 months after withdrawal and (ii another patient on amlodipine for 8 years developed Schamberg′s like purpuric pigmentation, which resolved on withdrawal of drug within 3 months. These findings have not been reported in the literature earlier. This study is presented for paucity of Indian data on ACDR due to antihypertensive drugs, and remarkable advancement in area of cardiovascular and antihypertensive pharmacology and a large number of population taking antihypertensive drugs.

  20. Subsidence due to geothermal fluid withdrawal

    Single-phase and two-phase geothermal reservoirs are currently being exploited for power production in Italy, Mexico, New Zealand, the U.S. and elsewhere. Vertical ground displacements of upto 4.5 m and horizontal ground displacements of up t o 0.5 m have been observed at Wairakei, New Zealand that are clearly attributable to the resource exploitation. Similarly, vertical displacements of about 0.13 m have been recorded at The Geysers, California. No significant ground displacements that are attributable to large-scale fluid production have been observed at Larderello, Italy and Cerro Prieto, Mexico. Observations show that subsidence due to geothermal fluid production is characterized by such features as an offset of the subsidence bowl from the main area of production, time-lag between production and subsidence and nonlinear stress-strain relationships. Several plausible conceptual models, of varying degrees of sophistication, have been proposed to explain the observed features. At present, relatively more is known about the physical mechanisms that govern subsidence than the relevant therma mechanisms. Although attempts have been made to simulate observed geothermal subsidence, the modeling efforts have been seriously limited by a lack of relevant field data needed to sufficiently characterize the complex field system.

ABSTRACT: Recent observations show that molecular clouds are not homogeneous, but clumpy. Some clumps are observed to be gravitationally unbound. How did these clumps then form? We suggest explaining these condensation as due to thermal instability aiding gravit y The cooling function per gram studied is of the general form A p T,where pand T are the density and temperature, respectively. We are interested in the maximum value of for which collapse still occurs. Various models are studied.

    Cochineal carmine, or simply carmine (E120), is a red colouring that is obtained from the dried bodies of the female insect Dactylopius coccus Costa (the cochineal insect). We have evaluated the prevalence of sensitization and asthma caused by carmine in a factory using natural colouring, following the diagnosis of two workers with occupational asthma. The accumulated incidence of sensitization and occupational asthma due to carmine in this factory are 48.1% and 18.5% respectively, figures that make the introduction of preventive measures obligatory. Occupational asthma caused by inhaling carmine should be considered as a further example of the capacity of certain protein particles of arthropods (in this case cochineal insects) to act as aeroallergens. Carmine should be added to the list of agents capable of producing occupational asthma, whose mechanism, according to our studies, would be immunological mediated by IgE antibodies in the face of diverse allergens of high molecular weight, which can vary from patient to patient. Nonetheless, given the existence of different components in carmine, it cannot be ruled out that substances of low molecular weight, such as carminic acid, might act as haptenes. Besides, since we are dealing with a colouring that is widely used as a food additive, as a pharmaceutical excipient and in the composition of numerous cosmetics, it is not surprising that allergic reactions can appear both through ingestion and through direct cutaneous contact. We find ourselves facing a new example of an allergen that can act through both inhalation and digestion, giving rise to an allergolical syndrome that can show itself clinically with expressions of both respiratory allergy and alimentary allergy.

    Endocarditis is a common disease in hospital practice. Identification of the microorganism responsible for the valvular damage is essential to establish the prognosis and to determine the optimal antibiotic treatment. In some cases of endocarditis the diagnosis is laborious, especially when the responsible microorganism is difficult to detect using standard culture techniques. Here we report a case of native aortic valve endocarditis due to Kingella kingae, a Gram negative organism of the HACEK group. In addition we review 6 other cases of endocarditis caused by organism belonging to this group, treated in our hospital between 1983 and 1999. Epidemiological studies show that less than 5% of all cases of endocarditis are caused by organisms of the HACEK group. The diagnosis is often delayed because their slow growth on a standard culture medium. We describe clinical and microbiological characteristics of this group of endocarditis.

  9. Buffering and proteolysis are induced by segmental monosomy in Drosophila melanogaster

    2012-01-01

    Variation in the number of individual chromosomes (chromosomal aneuploidy) or chromosome segments (segmental aneuploidy) is associated with developmental abnormalities and reduced fitness in all species examined; it is the leading cause of miscarriages and mental retardation and a hallmark of cancer. However, despite their documented importance in disease, the effects of aneuploidies on the transcriptome remain largely unknown. We have examined the expression effects of seven heterozygous chromosomal deficiencies, both singly and in all pairwise combinations, in Drosophila melanogaster. The results show that genes in one copy are buffered, i.e. expressed more strongly than the expected 50% of wild-type level, the buffering is general and not influenced by other monosomic regions. Furthermore, long genes are significantly more highly buffered than short genes and gene length appears to be the primary determinant of the buffering degree. For short genes the degree of buffering depends on expression level and expression pattern. Furthermore, the results show that in deficiency heterozygotes the expression of genes involved in proteolysis is enhanced and negatively correlates with the degree of buffering. Thus, enhanced proteolysis appears to be a general response to aneuploidy. PMID:22434883

    Full Text Available Cutaneous allergic reactions due to drug intake may be triggered by many types of drugs such as atropine, anticonvulsants and benzodiazepines. But allergic reactions due to benzodiazepines are extremely rare. Alprazolam is a benzodiazepine which may be useful for refractory idiopathic urticaria due to antihistaminergic effect. Although antihistaminergic effect of alprazolam, a cold urticaria case and an angioedema case induced by alprazolam are known in the literature. In the case, we present a child suffering from cutaneous allergic reaction due to alprazolam at the first dose taken. [Cukurova Med J 2016; 41(2.000: 400-402

  6. Scope and limitations of due process in administrative proceedings

    Bernardo Carvajal Sánchez

    2010-12-01

    Full Text Available In order to explain in a better way the scope of Due Process in Administrative Law as a legal norm whose respect is essential to all government agencies, three points of view (formal, structural and material are proposed. Those items seem useful to understand “Administrative Due Process” in all its dimensions: as a constitutional norm developed by the enactment of laws and decrees; as a principle inspiring some conducts and new norms; and as an objective and subjective fundamental right. On the other hand, it is shown that Administrative Due Process is not an absolute rule because in some cases its full application is subject to normative relativism. Two opposite trends can be perceived at this point: in the first place, government agencies usually do not act the same way judges do, so Administrative Due Process should be distinguished from Judicial Due Process; therefore, it could actually have a more restricted scope. In the second place, some administrative authorities are nowadays playing a role more or less similar to what judges do. This means that new procedural guarantees will be claimed. In any case, admitting valid limitations to Administrative Due Process leads to the quest of the limits of these limitations. The application of the rule of Due Process cannot be totally suppressed; its scope cannot be completely reduced. This is the result of its fundamental nature as a legal norm that ensures justice and equity in all administrative procedures, and proscribes random decisions.

    Full Text Available Observations to study the variation of attenuation of 3cm waves due to falling of water or artificial rain are confined to the high rates of precipitation and short distance between the transmitter and receiver, due to low power of the microwave generator. A comparison of these observations and those recorded by others shows that the attenuation increases nonlinearly with the intensity of artificial rainfall which is generally assumed to be linear for the observations at lower rates of precipitation.

    Full Text Available Abstract Background Burden of disease is a joint measure of mortality and morbidity which makes it easier to compare health problems in which these two components enjoy different degrees of relative importance. The objective of this study is ascertaining the burden of disease due to cancer in Spain via the calculation of disability-adjusted life years (DALYs. Methods DALYs are the sum of years of life lost due to premature mortality and years lost due to disability. World Health Organization methodology and the following sources of data were used: the Mortality Register and Princeton Model Life Table for Years of life lost due to premature mortality and population, incidence estimates (Spanish tumour registries and fitting of generalized linear mixed models, duration (from data of survival in Spain from the EUROCARE-3 study and fitting of Weibull distribution function and disability (weights published in the literature for Years lost due to disability. Results There were 828,997 DALYs due to cancer (20.5 DALYs/1,000 population, 61% in men. Of the total, 51% corresponded to lung, colorectal, breast, stomach and prostate cancers. Mortality (84% of DALYs predominated over disability. Subjects aged under 20 years accounted for 1.6% and those aged over 70 years accounted for 30.1% of DALYs. Conclusion Lung, colorectal and breast cancers are responsible for the highest number of DALYs in Spain. Even if the burden of disease due to cancer is predominantly caused by mortality, some cancers have a significant weight of disability. Information on 2000 burden of disease due to cancer can be useful to assess how it has evolved over time and the impact of medical advances on it in terms of mortality and disability.

    Full Text Available Background Lacunar syndrome not due to lacunar infarct is poorly characterised. This single centre, retrospective study was conducted to describe the clinical characteristics of patients with lacunar syndrome not due to lacunar infarct and to identify clinical predictors of this variant of lacunar stroke. Methods A total of 146 patients with lacunar syndrome not due to lacunar infarction were included in the "Sagrat Cor Hospital of Barcelona Stroke Registry" during a period of 19 years (1986-2004. Data from stroke patients are entered in the stroke registry following a standardized protocol with 161 items regarding demographics, risk factors, clinical features, laboratory and neuroimaging data, complications and outcome. The characteristics of these 146 patients with lacunar syndrome not due to lacunar infarct were compared with those of the 733 patients with lacunar infarction. Results Lacunar syndrome not due to lacunar infarct accounted for 16.6% (146/879 of all cases of lacunar stroke. Subtypes of lacunar syndromes included pure motor stroke in 63 patients, sensorimotor stroke in 51, pure sensory stroke in 14, atypical lacunar syndrome in 9, ataxic hemiparesis in 5 and dysarthria-clumsy hand in 4. Valvular heart disease, atrial fibrillation, sudden onset, limb weakness and sensory symptoms were significantly more frequent among patients with lacunar syndrome not due to lacunar infarct than in those with lacunar infarction, whereas diabetes was less frequent. In the multivariate analysis, atrial fibrillation (OR = 4.62, sensorimotor stroke (OR = 4.05, limb weakness (OR = 2.09, sudden onset (OR = 2.06 and age (OR = 0.96 were independent predictors of lacunar syndrome not due to lacunar infarct. Conclusions Although lacunar syndromes are highly suggestive of small deep cerebral infarctions, lacunar syndromes not due to lacunar infarcts are found in 16.6% of cases.

    2015-09-01

    Full Text Available This study empirically examined whether due process mechanism serve as an antidote for fraudulent practices in the Nigerian public sector. Using 875 subjects in the public sector, the Pearson Product-Moment Correlation statistical tool was employed in order to establish whether due process mechanism is an antidote for fraudulent practices and also to see if due process ensures transparency in the public sector. The study found that due process ensures transparency and is an antidote for fraudulent practices. Another interesting finding from extant literature was that weak internal control system encourages fraudulent practices in the public sector. Thus, the need to re-embark upon moral, religious, ethical and social re-orientation in the public sector on the path of economic progress and development and not for political advantages is eminent as well as rigorous campaigns to awaken the conscious and re-orientate public servants and the general society on the need to refrain from fraud or abetting it. The internal control system operating in the public sector needs to be strengthened. Also, there is need for institutionalizing, internalizing and building ownership for the multitude of reforms within the public sector so as to ensure that it sustains the changes in the anti-corruption campaign in Nigeria. These trends need to continue for the dividends of due process to be fully realized in the Nigerian public sector.

    The important thing in a patient in whom platelet values were detected to be greater than normal is whether thrombocytosis is a reactive phenomenon due to a different pathology or due to a clonal hematological pathology. In this case report, reactive thrombocytosis observed in a case with subclinical hypothyroidism due to Hashimoto's thyroiditis is reported; and according to our literature review, this is the first reported case of reactive thrombocytosis due to Hashimoto's thyroiditis and/or subclinical hypothyroidism. A 31-year-old man without any complaint was admitted to the Hematology Department for thrombocytosis which was detected in his routine follow-up. He had been using thyroid hormone replacement for 2 years because of hypothyroidism as Hashimoto's thyroiditis was earlier diagnosed. Due to miscommunication, he stopped his medication levothyroxine 0.1 mg/day 2 weeks in advance and he was still off-drug on admission. Platelet count was 715×10/l in the first admission center. Subclinical hypothyroidism diagnosis was made with the present findings and thyroid hormone replacement therapy was again commenced gradually. Platelet counts and thyroid-stimulating hormone value were normal 6 weeks later. As a result, before making diagnosis of thrombocytosis related to myeloproliferative disease or myelodysplastic syndromes, secondary causes should be investigated carefully.

  9. Migration rates of planets due to scattering of planetesimals

    Ormel, Chris; Tanaka, Hidekazu

    2012-01-01

    Planets migrate due to the recoil they experience from scattering solid (planetesimal) bodies. To first order, the torques exerted by the interior and exterior disks cancel, analogous to the cancellation of the torques from the gravitational interaction with the gas (type I migration). Assuming the dispersion-dominated regime and power-laws characterized by indices {\\alpha} and {\\beta} for the surface density and eccentricity profiles, we calculate the net torque on the planet. We consider both distant encounters and close (orbit-crossing) encounters. We find that the close and distant encounter torques have opposite signs with respect to their {\\alpha} and {\\beta} dependences; and that the torque is especially sensitive to the eccentricity gradient ({\\beta}). Compared to type-I migration due to excitation of density waves, the planetesimal-driven migration rate is generally lower due to the lower surface density of solids in gas-rich disk, although this may be partially or fully offset when their eccentricit...

  10. Failure of a MEA reclaimer tube bundle due to corrosion

    1988-08-01

    The removal of sulphur compounds from natural gas used in ammonia production is carried out by scrubbing with monoethanol amine (MEA). To avoid build up of corrosion and degradation products, a portion of the circulating MEA solution is passed through a reclaimer. This is essentially a kettle-type reboiler with a tube bundle made of 316L stainless steel. Occasional failures of the tube bundle due to pitting corrosion have been reported. It is suggested that the excessive pitting corrosion observed on the upper rows of the tube bundle could be partly due to high steam temperature but mainly due to the liquid level falling below the tubes leaving an accumulation of corrosive degradation products on the exposed surfaces, normally these corrosive products remain diluted in the MEA solution and cause little corrosion of the covered tubes. Their concentration on the dry upper layers of the hot metal tubes, however, leads to excessive corrosion. (U.K.).

    The genus Roseomonas comprises groups of slow-growing, Gram-negative coccobacilli, which only infrequently cause infection in humans. When identified, they are associated with immunocompromised adults, often causing bacteraemia. Due to their rarity, members of this genus can be overlooked or misidentified using automated laboratory identification systems. We report on an immunocompetent adolescent patient who developed septic arthritis due to Roseomonas gilardii following surgery for a sports injury. The isolate was initially misidentified as Bordetella bronchiseptica using the Vitek 2 system, but confirmed as R. gilardii based on 16S rRNA gene sequencing. To the best of our knowledge, this is the first case of a healthy paediatric patient with septic arthritis due to R. gilardii.

  13. Secondary Hemochromatosis due to Chronic Oral Iron Supplementation

    2017-01-01

    Iron may accumulate in excess due to a mutation in the HFE gene that upregulates absorption or when it is ingested or infused at levels that exceed the body's ability to clear it. Excess iron deposition in parenchymal tissue causes injury and ultimately organ dysfunction. Diabetes mellitus and hepatic cirrhosis due to pancreas and liver damage are just two examples of diseases that result from iron overload. Despite the rapid growth of information regarding iron metabolism and iron overload states, the most effective treatment is still serial phlebotomies. We present a patient who developed iron overload due to chronic ingestion of oral ferrous sulfate. This case illustrates the importance of querying geriatric patients regarding their use of nonprescription iron products without a medical indication. PMID:28133557

    Science.gov (United States)

    Squire, J; Bhattacharjee, A

    2015-11-01

    This article presents a calculation of the mean electromotive force arising from general small-scale magnetohydrodynamical turbulence, within the framework of the second-order correlation approximation. With the goal of improving understanding of the accretion disk dynamo, effects arising through small-scale magnetic fluctuations, velocity gradients, density and turbulence stratification, and rotation, are included. The primary result, which supplements numerical findings, is that an off-diagonal turbulent resistivity due to magnetic fluctuations can produce large-scale dynamo action-the magnetic analog of the "shear-current" effect. In addition, consideration of α effects in the stratified regions of disks gives the puzzling result that there is no strong prediction for a sign of α, since the effects due to kinetic and magnetic fluctuations, as well as those due to shear and rotation, are each of opposing signs and tend to cancel each other.

  16. Detection of Lense-Thirring Effect Due to Earth's Spin

    CERN Document Server

    Ciufolini, I; Vespe, F; Chieppa, F

    1997-01-01

    Rotation of a body, according to Einstein's theory of general relativity, generates a "force" on other matter; in Newton's gravitational theory only the mass of a body produces a force. This phenomenon, due to currents of mass, is known as gravitomagnetism owing to its formal analogies with magnetism due to currents of electric charge. Therefore, according to general relativity, Earth's rotation should influence the motion of its orbiting satellites. Indeed, we analysed the laser ranging observations of the orbits of the satellites LAGEOS and LAGEOS II, using a program developed at NASA/GSFC, and obtained the first direct measurement of the gravitomagnetic orbital perturbation due to the Earth's rotation, known as the Lense-Thirring effect. The accuracy of our measurement is about 25%.

  17. A canned food scheduling problem with batch due date

    Chung, Tsui-Ping; Liao, Ching-Jong; Smith, Milton

    2014-09-01

    This article considers a canned food scheduling problem where jobs are grouped into several batches. Jobs can be sent to the next operation only when all the jobs in the same batch have finished their processing, i.e. jobs in a batch, have a common due date. This batch due date problem is quite common in canned food factories, but there is no efficient heuristic to solve the problem. The problem can be formulated as an identical parallel machine problem with batch due date to minimize the total tardiness. Since the problem is NP hard, two heuristics are proposed to find the near-optimal solution. Computational results comparing the effectiveness and efficiency of the two proposed heuristics with an existing heuristic are reported and discussed.

    2015-12-01

    Full Text Available Context Staphylococcus aureus and coagulase-negative staphylococci (CoNS are the most frequently isolated pathogens and are responsible for approximately two-thirds of joint replacement infections. Evidence Acquisition Although both belong to the staphylococci genus, there are several epidemiological and therapeutic differences between S. aureus and the heterogenous group of CoNS. In general, however, preventive and therapeutic recommendations for Prosthetic Joint Infection PJI due to CoNS do not differ from PJI caused by other pathogens. Results The main differences between the pathogens lie in the clinical presentation of PJI, the presumed origin of infection, and the presence of a higher proportion of methicillin-resistant strains leading to a limited choice of antibiotic agents. Conclusions Fortunately, due to its lower virulence as compared to its cousin S. aureus, PJI due to CoNS may display higher remission rates than S. aureus-caused PJI after combined surgical and medical management.

    Full Text Available Gossypiboma, an infrequent surgical complication, is a mass lesion due to a retained surgical sponge surrounded by foreign body reaction. In this case report, we describe gossypiboma in the abdominal cavity which was detected 14 months after the hysterectomy due to acute abdominal pain. Gossypiboma was diagnosed by computed tomography (CT. The CT findings were a rounded mass with a dense central part and an enhancing wall. In explorative laparotomy, small bowel loops were seen to be perforated due to inflammation of long standing gossypiboma. Jejunal resection with end-to-end anastomosis was performed. The patient was discharged whithout complication. This case was presented to point to retained foreign body (RFB complications and we believed that the possibility of a retained foreign body should be considered in the differential diagnosis of who had previous surgery and complained of pain, infection, or palpable mass.

    Damage to lung parenchyma due to blunt thoracic trauma often appears as contusion or hematoma. Cavitary lung lesions or pseudocyst formation due to trauma is a rare phenomenon. In the literature traumatic pseudocysts are also known as pseudocystic hematomas, traumatic lung cavity and traumatic pneumotocel. Traumatic pseudocysts usually have good clinical prognosis, recover spontaneously with supportive treatment and do not require surgery. In this article, we present the case of 52 year old male who was brought to the emergency department after a fall from height and was diagnosed with lung contusions and traumatic cyst.

    Patients with reactions to topical products may be eliciting a physical urticaria, dermographism, by rubbing. These reactions may be misinterpreted as allergic, and three cases demonstrating this phenomenon were reviewed. All patients with reactions to topical products due to dermographism improved with counseling and antihistamine therapy. Repeat open application testing confirmed the safety of previously suspect medications in two of the three cases, preventing unnecessary changes in the medication regimens and inaccurate diagnoses of medication allergy. We observe that intolerance to topical medications due to dermographism can usually be managed without extensive testing or treatment.

    2008-09-15

    Radiological impacts of phosphate rocks mining and manufacture could be significant due to the elevated radioactivity contents of the naturally occurring radioactive materials (NORM), such as {sup 238}U series, {sup 232}Th series and {sup 40}K, in some phosphate deposits. Over the last decades, the land reclamation and agriculture activities in Saudi Arabia and other countries have been widely expanded. Therefore, the usage of chemical fertilizers is increased. Selected phosphate fertilizers samples were collected and the specific activities of NORM were measured using a gamma ray spectrometer based on a hyper pure germanium detector and alpha spectrometer based on surface barrier detector. The obtained results show remarkable wide variations in the radioactivity contents of the different phosphate fertilizer samples. The mean (ranges) of specific activities for {sup 226}Ra, {sup 210}Po, {sup 232}Th and {sup 40}K, and radium equivalent activity are 75 (3-283), 25 (0.5-110), 23 (2-74), 2818 (9-6501) Bq/kg and 283 (7-589) Bq/kg, respectively. Based on dose calculations, the increment of the public radiation exposure due to the regular agricultural usage of phosphate fertilizers is negligible. Its average value 1 m above the ground is about 0.12 nGy/h where the world average value due to the NORM in soil is 51 nGy/h. Direct radiation exposures of the farmers due to phosphate fertilizers application was not considered in our study.

    Finite element analysis is used to calculate the shape of blisters formed in bilayer optical storage media due to the buildup of thermal stresses during laser writing. It is shown that practically usable blisters may be expected to form in a time period of about 15 ns. Such a thermal stress delamination process may also precede melting in conventional pit formation processes.

    Full Text Available Abstract Introduction We present a case of cardiac arrest due to hypokalemia caused by lymphocytic colitis. Case presentation A 69-year-old Caucasian man presented four months prior to a cardiac arrest with watery diarrhea and was diagnosed with lymphocytic colitis. Our patient experienced a witnessed cardiac arrest at his general practitioner's surgery. Two physicians and the emergency medical services resuscitated our patient for one hour and four minutes before arriving at our university hospital. Our patient was defibrillated 16 times due to the recurrence of ventricular tachyarrhythmias. An arterial blood sample revealed a potassium level of 2.0 mmol/L (reference range: 3.5 to 4.6 mmol/L and pH 6.86 (reference range: pH 7.37 to 7.45. As the potassium level was corrected, the propensity for ventricular tachyarrhythmias ceased. Our patient recovered from his cardiac arrest without any neurological deficit. Further tests and examinations revealed no other reason for the cardiac arrest. Conclusion Diarrhea can cause life-threatening situations due to the excretion of potassium, ultimately causing cardiac arrest due to hypokalemia. Physicians treating patients with severe diarrhea should consider monitoring their electrolyte levels.

    2009-04-01

    Expected loss and damage assessment due to natural and technological disasters are of primary importance for emergency management just after the disaster, as well as for development and implementation of preventive measures plans. The paper addresses the procedures and simulation models for loss estimations due to strong earthquakes and secondary technological accidents. The mathematical models for shaking intensity distribution, damage to buildings and structures, debris volume, number of fatalities and injuries due to earthquakes and technological accidents at fire and chemical hazardous facilities are considered, which are used in geographical information systems assigned for these purposes. The criteria of technological accidents occurrence are developed on the basis of engineering analysis of past events' consequences. The paper is providing the results of scenario earthquakes consequences estimation and individual seismic risk assessment taking into account the secondary technological hazards at regional and urban levels. The individual risk is understood as the probability of death (or injuries) due to possible hazardous event within one year in a given territory. It is determined through mathematical expectation of social losses taking into account the number of inhabitants in the considered settlement and probability of natural and/or technological disaster.

  6. Clozapine underutilization and discontinuation in African Americans due to leucopenia.

    Kelly, Deanna L; Kreyenbuhl, Julie; Dixon, Lisa; Love, Raymond C; Medoff, Deborah; Conley, Robert R

    2007-09-01

    Clozapine use has been notably lower in African American patients than in Caucasians. It has been suggested that lower normal ranges for white blood cell (WBC) counts in African Americans, known as benign ethnic neutropenia, may account partially for the disparity. We examined the rates of leucopenia and agranulocytosis as reasons for discontinuation of clozapine in a sample of 1875 patients with schizophrenia treated in the State of Maryland. Between 1989 and 1999, 5.3% (31/588) of African Americans and 2.4% (31/1287) of Caucasians discontinued clozapine treatment due to leucopenia (chi square = 10.35, df = 1, P = 0.001). No African American patients developed agranulocytosis while 8 Caucasian patients (0.62%) developed this blood dyscrasia. Discontinuations due to leucopenia occurred throughout treatment. Discontinuations due to agranulocytosis occurred primarily in the first 18 weeks (7/8; 87.5% patients with agranulocytosis). It is likely that African Americans had clozapine discontinued unnecessarily due to benign ethnic neutropenia. We concur with recent recommendations to acknowledge differences in WBC values in African Americans and to modify prescribing guidelines or formally acknowledge benign ethnic leucopenia like in other countries in order to facilitate greater use of clozapine in these patients.

We believe this is a novel finding, previously unreported in the literature, of transient embolic occlusion without permanent visual sequelae due to a malignant primary cardiac pleomorphic sarcoma.

    Poland has one of the highest cervical cancer mortality rates in Europe. It is related to the problem of late diagnosis and low attendance rate in screening programs. The objective of the study has been to assess the annual production loss due to the cervical cancer morbidity and mortality in Poland in 2012. The outcomes have been to provide comprehensive information on cervical cancer's influence on population's ability to work and its overall economic burden for the society. The study has also provided the methodological framework for disease-related production losses in Polish settings. The human capital method was used. The production losses were calculated in both monetary and quantitative terms (working days lost) due to 4 following reasons: 1) temporary disability to work, 2) permanent disability, 3) informal care, and 4) mortality. Cervical cancer resulted in approx. 702 964 working days lost in 2012 due to absence at work for both patients and care givers and a total number of 957 678 working days lost due to patients' mortality. The total value of production lost was assessed at 111.4 million euros. More than 66% of this value was attributed to women's mortality. The calculation of production lost due to cervical cancer burden provides strong evidence to support adequate health promotion and disease prevention actions. Actions promoting cervical cancer screening should be intensified including workplace health promotion activities. Med Pr 2016;67(3):289-299.

    AIM: To describe the diagnostic criteria for acute liver failure due to Wilson disease (WD), which is an uncommon cause of acute liver failure (ALF).METHODS: We compared findings of patients presenting with ALF due to WD to those with ALF of other etiologies.RESULTS: Previously described criteria, such as low alkaline phosphatase activity, ratio of low alkaline phosphatase to total bilirubin or ratio of high aspartate aminotransferase (AST) to alanine aminotransferase (ALT), failed to identify patients with ALF due to WD. There were significant differences in low ALT and AST activities (53 ± 43 vs 1982 ± 938, P < 0.0001 and 87 ± 44 vs 2756 ± 2941, P = 0.037, respectively), low choline esterase activity (1.79 ± 1.2 vs 4.30 ± 1.2, P = 0.009), high urine copper concentrations (93.4 ± 144.0 vs 3.5 ± 1.8, P = 0.001) and low hemoglobin (7.0 ± 2.2 vs 12.6 ± 1.8, P < 0.0001) in patients with ALF caused by WD as compared with other etiologies. Interestingly, 4 of 7 patients with ALF due to WD survived without liver transplantation.CONCLUSION: In ALF, these criteria can help establish a diagnosis of WD. Where applicable, slit-lamp examination for presence of Kayser-Fleischer rings and liver biopsy for determination of hepatic copper concentration still remain important for the diagnosis of ALF due to WD. The need for liver transplantation should be evaluated carefully as the prognosis is not necessarily fatal.

  12. Two families with sibling recurrence of the 17q21.31 microdeletion syndrome due to low-grade mosaicism

    The 17q21.31 microdeletion syndrome is characterised by intellectual disability, epilepsy, distinctive facial dysmorphism, and congenital anomalies. To date, all individuals reported with this syndrome have been simplex patients, resulting from de novo deletions. Here, we report sibling recurrence of the 17q21.31 microdeletion syndrome in two independent families. In both families, the mother was confirmed to be the parent-of-origin for the 17q21.31 deletion. Fluorescence in situ hybridisation analyses in buccal mucosa cells, of the mother of family 1, identified monosomy 17q21.31 in 4/50 nuclei (8%). In mother of family 2, the deletion was identified in 2/60 (3%) metaphase and in 3/100 (3%) interphase nuclei in peripheral lymphocytes, and in 7/100 (7%) interphase nuclei in buccal cells. A common 17q21.31 inversion polymorphism predisposes to non-allelic homologous recombination and hereby to the 17q21.31 microdeletion syndrome. On the basis of the 17q21.31 inversion status of the parents, we calculated that the probability of the second deletion occurring by chance alone was 1/14 438 and 1/4812, respectively. If the inversion status of the parents of a child with the 17q21.31 microdeletion syndrome is unknown, the overall risk of a second child with the 17q21.31 microdeletion is 1/9461. We conclude that the presence of low-level maternal somatic–gonadal mosaicism is associated with the microdeletion recurrence in these families. This suggests that the recurrence risk for parents with a child with a 17q21.31 microdeletion for future pregnancies is higher than by chance alone and testing for mosaicism in the parents might be considered as a helpful tool in the genetic counselling.

    Introduction: The fungal genus Colletotrichum is an uncommon cause of human infections. It has been implicated in cutaneous phaeohyphomycosis, artritis and keratitis secondary to traumatic implantation. Case presentation: We report two cases of keratitis due Colletotrichum truncatum in middle-aged, immunocompetent persons without history of trauma. The aetiological agents were identified based on DNA sequencing. Azoles and echinocandins showed high minimal inhibitory concentrations while amphotericin B was ≤ 0.25  mg l−1. Both patients failed topical antifungal treatment and needed penetrating keratoplasty with a favourable outcome. Conclusion: C. truncatum caused keratomycosis which did not respond to topical antifungal agents. To the best of our knowledge these are the first reported cases of keratitis due to this fungus in Cuba and Latin-America and highlights the expanding spectrum of fungal agents causing eye infections.

    2010-12-01

    The high rates of morbidity and mortality after subarachnoid hemorrhage due to spontaneous rupture of an intracranial aneurysm are mainly the result of neurologic complications. Sixty years after cerebral vasospasm was first described, this problem remains unsolved in spite of its highly adverse effect on prognosis after aneurysmatic rupture. Treatment is somewhat empirical, given that uncertainties remain in our understanding of the pathophysiology of this vascular complication, which involves structural and biochemical changes in the endothelium and smooth muscle of vessels. Vasospasm that is refractory to treatment leads to cerebral infarction. Prophylaxis, early diagnosis, and adequate treatment of neurologic complications are key elements in the management of vasospasm if neurologic damage, lengthy hospital stays, and increased use of health care resources are to be avoided. New approaches to early treatment of cerebral lesions and cortical ischemia in cases of subarachnoid hemorrhage due to aneurysm rupture should lead to more effective, specific management.

    Full Text Available In dogs, dermatitis due to mixed mite infestation is rare. During the five-year period of study, two dogs were identified suffering from dermatitis due to mixed Demodex and Sarcoptes mites. Upon clinical examination dogs had primary and secondary skin lesions on face, around the ears, chin, neck, fore limbs and lateral abdomen. Microscopic examination of skin scrapings revealed Demodex and Sarcoptes mites. Both dogs were treated with daily oral ivermectin at 100 to 400 μg/kg body weight as incremental doses, external application of amitraz and supportive treatments with topical antimicrobial shampoo. After completion of forty-two days of therapy, dogs were recovered from the dermatitis.

    2015-01-01

    Agranulocytosis is a rare complication of levamisole. We report a 22-year-old female who developed agranulocytosis due to levamisole. The patient initially presented with salmonellosis and agranulocytosis, and then she recovered with treatment. However, 2 months after discharge, she again presented with tonsillitis and agranulocytosis. This time the family revealed that she had been taking levamisole. Though Salmonella infection is a recognized cause of agranulocytosis, any patient presenting with repeated agranulocytosis after an initial recovery should make the clinician suspect another cause, especially drug-induced. A case of Salmonella infection where levamisole was an unsuspecting cause of agranulocytosis has not been described in indexed literature. Recurrent agranulocytosis due to repeated exposure to levamisole has also not been described.

  19. Acceleration of Small Dust Grains due to Charge Fluctuations

    CERN Document Server

    Hoang, Thiem

    2011-01-01

    We consider the acceleration of very small dust grains including Polycyclic Aromatic Hydrocarbons (PAHs) arising from the electrostatic interactions of dust grains that have charge fluctuates in time due to charging events. We simulate the charge fluctuations of very small grains due to their sticking collisions with electrons and ions in plasma and the emission of photoelectrons by UV photons using Monte Carlo method. We identify the acceleration induced by the charge fluctuations as the dominant acceleration mechanism of very small grains in the diffuse interstellar medium (ISM). We show that this acceleration mechanism is more efficient for environments with low ionization, where the charge fluctuations are slow but have a large amplitude. We also discuss the implications of the present mechanism for grain coagulation and shattering in the diffuse ISM, molecular clouds and protoplanetary disks.

    This manuscript describes two interesting patients who had exercise-induced symptoms that unmasked an alternative underlying diagnosis. The first is an 8-year-old boy who was treated for asthma all his life but really had exercise-induced stridor (labelled as wheeze) causing significant exercise limitation, which was due to a double aortic arch with the right arch compressing the trachea. The second case describes the diagnosis of vocal cord dysfunction in a 13-year-old anxious high achiever. He also initially had exercise-induced symptoms treated as exercise-induced wheeze but again had a stridor due to vocal cord dysfunction. Both these cases demonstrate the importance of detailed history including during exercise, which can unmask alternative diagnosis. Another important message is that if there is no response to bronchodilator treatment with absence of typical signs and symptoms of asthma, alternative diagnosis should be considered.

    2015-06-01

    Condom catheters are often used in the management of male urinary incontinence, and are considered to be safe. As condom catheters are placed on the male genitalia, sometimes adequate care is not taken after placement owing to poor medical care of debilitated patients and feelings of embarrassment and shame. Similarly, sometimes the correct size of penile sheath is not used. Strangulation of penis due to condom catheter is a rare condition; only few such cases have been reported in the literature. Proper application and routine care of condom catheters are important in preventing this devastating complication especially in a neurologically debilitated population. We present a case of penile necrosis due to condom catheter. We will also discuss proper catheter care and treatment of possible complications.

  2. A solar cycle of spacecraft anomalies due to internal charging

    Directory of Open Access Journals (Sweden)

    G. L. Wrenn

    Full Text Available It is important to appreciate how the morphology of internal charging of spacecraft systems, due to penetrating electrons, differs from that of the more common surface charging, due to electrons with lower energy. A specific and recurrent anomaly on a geostationary communication satellite has been tracked for ten years so that solar cycle and seasonal dependencies can be clearly established. Concurrent measurements of sunspot number, solar wind speed and 2-day >2 MeV electron fluence are presented to highlight pertinent space weather relationships, and the importance of understanding the complex particle interaction processes involved.

    By the description of two cases of osteoarticular infections due to Kingella kingae in two young children we wish to draw the attention of clinicians to invasive infections due to this micro-organism. Since its biological characterization in 1976, K. kingae has been increasingly reported as a human pathogen. Most common presentations are endocarditis, bacteraemia, septic arthritis, osteomyelitis and spondylodiscitis. Interestingly, osteorticular involvement is largely predominant in previously healthy children. From the literature, we reviewed 51 cases of K. kingae bone and joint infections, representing 23 cases of septic arthritis, 17 of osteomyelitis and 11 spondylodiscitis. Of the cases 88% occurred in children below 5 years of age and in all cases only one bone or joint was involved. An underlying disorder could be found in only 4 patients. Since these infections have a favourable outcome with intravenous antibiotic treatment, proper isolation and identification of K. kingae is essential.

    Full Text Available Agranulocytosis is a rare complication of levamisole. We report a 22-year-old female who developed agranulocytosis due to levamisole. The patient initially presented with salmonellosis and agranulocytosis, and then she recovered with treatment. However, 2 months after discharge, she again presented with tonsillitis and agranulocytosis. This time the family revealed that she had been taking levamisole. Though Salmonella infection is a recognized cause of agranulocytosis, any patient presenting with repeated agranulocytosis after an initial recovery should make the clinician suspect another cause, especially drug-induced. A case of Salmonella infection where levamisole was an unsuspecting cause of agranulocytosis has not been described in indexed literature. Recurrent agranulocytosis due to repeated exposure to levamisole has also not been described.

    2015-01-01

    A recent article by Wojtak {\\it et al} (arXiv:1504.00178) pointed out that the local gravitational redshift, despite its smallness ($\\sim 10^{-5}$), can have a noticeable ($\\sim 1\\%$) systematic effect on our cosmological parameter measurements. The authors studied a few extended cosmological models (non-flat $\\Lambda$CDM, $w$CDM, and $w_0$-$w_a$CDM) with a mock supernova dataset. We repeat this calculation and find that the $\\sim 1\\%$ biases are due to strong degeneracy between cosmological parameters. When Cosmic Microwave Background (CMB) data are added to break the degeneracy, the biases due to local gravitational redshift are negligible ($\\lesssim 0.1 \\sigma$).

    We study the electric field and temperature gradient driven magnetoconductivity of a Weyl semimetal system. To analyze the responses, we utilize the kinetic equation with semiclassical equations of motion modified by the Berry curvature and orbital magnetization of the wave packet. Apart from the known positive quadratic magnetoconductivity, we show that due to the chiral anomaly, the magnetoconductivity can become a nonanalytic function of the magnetic field, proportional to the 3/2 power of the magnetic field at finite temperatures. We also show that time-reversal symmetry breaking tilt of the Dirac cones results in linear magnetoconductivity. This is due to the one-dimensional chiral anomaly for which the tilt is responsible.

    2015-12-01

    Full Text Available International trade is business transactions conducted across borders, which has the goal accumulated maximum profit (profit optimal. In this implementation, corporations often do business by unfair competition, such as dumping, which could damage the order of the importing country trading system. The problem is what factors are causing a corporation carrying out the practice of dumping, and also; and How is legal protection against a country as a result of dumping practices. Factors that cause dumping, to profit by setting lower prices in the import market and the monopoly in the market of the importing country. A form of protection for countries that suffered losses as a result of dumping practices which could impose "anti-dumping duty", as a punishment for the exporting country. Due to losses caused by dumping, the government should make a law that specifically regulates the protection of domestic industry due to the practice of dumping.

    Fungal keratitis due to Schizophyllum commune is very rare. In this study, we report the clinical and microbiological profile of five patients with fungal keratitis due to S. commune. Direct microscopic examination of corneal scrapings from all five patients showed septate branching hyaline fungal filaments. Similarly, in all five patients Sabouraud dextrose agar (SDA) plates inoculated with corneal scrapings showed white, cottony colonies on the second day of incubation. Lactophenol cotton blue stained wet preparation of 7-day-old colonies on SDA revealed clamp connections and no spores. The fungus was identified by its characteristic clamp connections, fan-shaped bracket fruiting body with pinkish-grey longitudinally split-radiating gills. The phenotypic identification of one of the five isolates further conformed by ITS sequencing. Treatment outcome was available for two of the five patients; in these two patients, the keratitis resolved with topical natamycin. © 2016 Blackwell Verlag GmbH.

    Due to technical innovations and strict safety regulations the rate and mortality of accidents caused by electric current has been considerably reduced. Nevertheless there are still deaths caused by electric shock, which are mostly due to carelessness and ignorance. The described death by electric shock of a 39-year-old man was the consequence of an electrotechnical curiosity. When repairing a cut extender cable, he installed a second socket on the one part and a second plug on the other. On the day of the accident, he first plugged the part of the cable with the two plugs into a wall socket. Then, as he tried to connect it with the other part, he was electrocuted.

  14. Correction due to finite speed of light in absolute gravimeters

    Nagornyi, V D; Zanimonskiy, Y Y

    2010-01-01

    Correction due to finite speed of light is among the most inconsistent ones in absolute gravimetry. Formulas reported by different authors yield corrections scattered up to 8 $\\mu$Gal with no obvious reasons. The problem, though noted before, has never been studied, and nowadays the correction is rather postulated than rigorously proven. In this paper we investigate the problem from several prospectives, find the corrections for different types of absolute gravimeters, and establish relationships between different ways of implement them. The obtained results enabled us to analyze and understand the discrepancies in the results of other authors. We found that the correction derived from the Doppler effect is accountable only for $\\tfrac{2}{3}$ of the total correction due to finite speed of light, if no signal delays are considered. Another major source of inconsistency was found in the tacit use of simplified trajectory models.

    In February 2011, the Food and Drug Administration informed that prescription of proton pump inhibitor (PPI) drugs may cause low serum magnesium levels if taken for prolonged periods of time. We present an ex-smoker, 76-year-old man, with high blood pressure, diabetes mellitus and Barrett's oesophagus (treated with esomeprazole since 2003) admitted due to fluctuating aphasia. Neurovascular and neuroimaging studies were normal. Dyslipidemia and atrial arrhythmia were discovered. The patient was discharged with the diagnosis of left middle cerebral artery transient ischaemic attack and anticoagulation treatment was recommended. The patient returned to the emergency department on further two occasions (confusional episodes) and was admitted in order to complete the neurological study that was normal. The patient was discharged with the diagnosis of probable epileptic seizures. After a week, he was admitted due to generalised temblor and unsteadiness. A complete blood test was performed and showed a severe hypomagnesaemia (not previously performed). PMID:23917371

  16. Analysis of mechanism of shock bump due to roof fall

    GU Xin-jian; LI Jian-xiong

    2004-01-01

    According to the characteristics of the shock bump due to roof fall, a simple mechanics model has been established by applying the catastrophic theory and the law of energy conservation. The author suggests that the shock bump may be induced by the sudden energy release in the roof falling after underground mineral extractions, and through the systematic analysis of actual examples on site, the empirical formulae for the roof falling and energy release are derived, which would provide a new way for the study of the origin and mechanism of mine tremor due to fallen-in roof structure. It is of a great importance to enrich the shock bump theory and production safety in mine.

    Respiratory syncytial virus (RSV) is the most frequent cause of hospitalization and an important cause of death in infants in the developing world. The relative contribution of social, biologic, and clinical risk factors to RSV mortality in low-income regions is unclear. To determine the burden and risk factors for mortality due to RSV in a low-income population of 84,840 infants. This was a prospective, population-based, cross-sectional, multicenter study conducted between 2011 and 2013. Hospitalizations and deaths due to severe lower respiratory tract illness (LRTI) were recorded during the RSV season. All-cause hospital deaths and community deaths were monitored. Risk factors for respiratory failure (RF) and mortality due to RSV were assessed using a hierarchical, logistic regression model. A total of 2,588 (65.5%) infants with severe LRTI were infected with RSV. A total of 157 infants (148 postneonatal) experienced RF or died with RSV. RSV LRTI accounted for 57% fatal LRTI tested for the virus. A diagnosis of sepsis (odds ratio [OR], 17.03; 95% confidence interval [CI], 13.14-21.16 for RF) (OR, 119.39; 95% CI, 50.98-273.34 for death) and pneumothorax (OR, 17.15; 95% CI, 13.07-21.01 for RF) (OR, 65.49; 95% CI, 28.90-139.17 for death) were the main determinants of poor outcomes. RSV was the most frequent cause of mortality in low-income postneonatal infants. RF and death due to RSV LRTI, almost exclusively associated with prematurity and cardiopulmonary diseases in industrialized countries, primarily affect term infants in a developing world environment. Poor outcomes at hospitals are frequent and associated with the cooccurrence of bacterial sepsis and clinically significant pneumothoraxes.

    Stopping power due to ion wave excitations is derived for a charged particle moving in a two-component plasma. Unlike previous theories based on ion-acoustic-wave approximation (IAWA), the excitation of short-wavelength ion waves is taken into account. The obtained stopping power has a magnitude larger than that of IAWA. Stopping power at subsonic velocities, where stopping power in IAWA disappears, is even larger than that of supersonic velocities.

    A three day old male, term infant with hemothorax due to hemorrhagic disease of the newborn was treated successfully with vitamin K and thoracocentesis. Exclusive breast feeding and absence of vitamin K prophylaxis were important diagnostic clues, although hemothorax as a sole manifestation of hemorrhagic disease of the newborn is rare. This case highlighted the good prognosis of an uncommon complication when prompt diagnosis and appropriate treatment are instituted. The importance of vitamin K prophylaxis to all newborns is emphasized.

    Full Text Available Although most of the scorpion stings are harmless, deadly species of scorpions may cause multiorgan failure, neurotoxicity, cardiotoxicity, and pulmonary edema. The cases should be observed in the emergency department against the possibility of development of systemic effects. Fatal complications, in particular such as pulmonary edema, and myocarditis should be considered. In this study, a case of myocarditis and pulmonary edema was detected on the patient who had applied to the emergency department due to a scorpion sting is presented.

    Stopping power due to ion wave excitations is derived for a charged particle moving in a two-component plasma. Unlike previous theories based on ion-acoustic-wave approximation (IAWA), the excitation of short-wavelength ion waves is taken into account. The obtained stopping power has a magnitude larger than that of IAWA. Stopping power at subsonic velocities, where stopping power in IAWA disappears, is even larger than that of supersonic velocities.

    Duplications of the oesophagus are uncommon congenital malformations with possible occurrence in any part of the gastrointestinal tract. The duplications may be cysts, diverticula or tubular-shaped. Cysts may even occur further away from the gastrointestinal tract, not necessarily having contact with it. I present a patient case, in which a 13-month-old child was brought to the emergency room due to gradually increasing dyspnea. The child made a full recovery after the surgical procedure.

  14. Heat Loss Due To Thermal Bridges In Buildings

    Building envelopes often contain numerous highly conductive heat flow paths, called thermal bridges, which are major sources of heat loss and deterioration of building materials due to moisture condensation. Some examples of thermal bridges occurring in office buildings are presented. Infrared thermography was used to identify the locations and magnitudes of thermally defective areas resulting from inadequate construction, design, or substandard workmanship in existing buildings. Due to the large thermal inertia of building components and transient conditions caused by fluctuating outdoor and indoor temperatures, long measurement periods are required. This makes thermography impractical for quantifying the heat loss. In order to estimate the heat loss rate from thermal bridges and to obtain a better understanding of the physical processes involved, a two-dimensional heat flow model has been developed for transient heat conduction within the exterior wall/intermediate floor systems. The calculated results from the mathematical model are compared with available experimental data. An in-situ measurement technique, which is currently under development at NBS for quantifying the energy loss due to thermal bridges, is described.

    Full Text Available BACKGROUND: Sleep disturbance is a risk factor for somatic, psycho-social and spiritual dysfunction. It is also arguably the most deleterious effect of traffic noise pollution. Quantification of its burden is an anchor element of environmental policy making but no data are currently available for Bulgaria where the preponderance of dangerous nighttime noise exposure is highest in Europe. AIM: The aim of this study was to quantify the socio-economic burden of severe sleep disturbance due to traffic noise (road, aircraft and railway in Bulgaria. MATERIAL AND METHODS: The official World Health Organization methodology used in Europe was applied in order to estimate this annual loss expressed as disability-adjusted life-years (DALYs and their corresponding monetary value (assuming € 12 000 per DALY. RESULTS: Results showed that severe sleep disturbance due to all traffic sources was associated conservatively with 15 468 DALYs (8 839 - 22 097 and € 185 615 861 (€ 106 066 206 - € 265 165 516 lost in 2012, with road traffic being the single most important noise source. CONCLUSION: In conclusion, severe sleep disturbance due to traffic noise bears a heavy environmental and socio-economic burden in Bulgaria which prompts vigorous political action and greater involvement in environmental research. In order to increase the accuracy of future burden of disease analyses other studies would need to establish exposure-response functions based on population-based socio-acoustic surveys in the country.

  17. Redshift and Blueshift are due to the Medium Composition

    Science.gov (United States)

    2017-01-01

    The redshift is the shift from shorter wavelengths towards longer wavelengths [or from higher wave frequency to lower wave frequency]. And, reciprocally, the blueshift is the shift from longer wavelengths towards shorter wavelengths [or from lower wave frequency towards higher wave frequency]. The General Theory of Relativity asserts that the redshift and blueshift are entirely due to the Doppler's Effect, which is caused by the motion of light source: if the source is moving away from the observer the frequency received is lower [redshift], but if the source is moving towards the observer the frequency received is higher [blueshift]. But Doppler's Effect itself is actually an appearance to a Subjective Observer, because the frequency is the same all over (if one considers the Absolute Observer). We believe that the redshift and blueshift are not entirely due to the Doppler's Effect, but also due (as in the light bending) to the medium composition (medium that could be formed by waves, particles, plasma, dust, gaseous, fluids, solids, etc.), to the medium density, to the medium heterogeneity, to the medium structure, and to the electromagnetic and gravitational fields contained in that medium that may interfere with the light that passes through.

    Full Text Available Eagle Syndrome (ES is a rare syndrome characterized by a specific orofacial pain due to a calcified stylohyoid ligament or an elongated styloid process. The ‘Classic’ Eagle Syndrome typically occurs after pharyngeal trauma or tonsillectomy. The second form, ‘Stylocarotid Syndrome’ is characterized by compression of internal or external carotid artery. Here, we present a case of acute dysphagia in a 48years old male due to Eagle Syndrome. The patient presented with acute onset dysphagia of 1 week duration to both solid and liquid foods, associated with odynophagia and pain in the right oropharynx. Patient had a past history of left hemiparesis with facial palsy due to right sided cerebrovascular accident (CVA 3years ago, which had subsequently improved. Patient was investigated with Barium swallow, X-ray skull lateral view, MR Angiogram of neck and brain, Carotid Doppler study and finally Orthopantomogram (OPG. OPG showed an elongated styloid process measuring 3.8cms on the right side. Incidentally, MR Angiogram of neck and brain showed absent intracranial part of internal carotid artery on the right side (the main stem of the artery, starting from 2mms from the common carotid bifurcation until the junction with anterior cerebral artery was missing.Rest all investigations were normal. Hence, the case was diagnosed as right sided Eagle syndrome, possibly of the stylocarotid variety

    Brucellosis is a serious public health issue in India. Estimation of economic losses occurring due to brucellosis is required to help formulate prevention and control strategies, but has not been done in India. We estimated economic losses due to brucellosis by sourcing prevalence data from epidemiological surveys conducted in India. Data for livestock populations were obtained from official records. Probability distributions were used for many of the input parameters to account for uncertainty and variability. The analysis revealed that brucellosis in livestock is responsible for a median loss of US $ 3.4 billion (5th-95th percentile 2.8-4.2 billion). The disease in cattle and buffalo accounted for 95.6% of the total losses occurring due to brucellosis in livestock populations. The disease is responsible for a loss of US $ 6.8 per cattle, US$18.2 per buffalo, US $ 0.7 per sheep, US $ 0.5 per goat and US $ 0.6 per pig. These losses are additional to the economic and social consequences of the disease in humans. The results suggest that the disease causes significant economic losses in the country and should be controlled on a priority basis.

    Genetic factors are involved in determinants for the risk of psychiatric disorders, and neurological and neurodegenerative diseases. Chronic pain stimuli and intense pain have effects at a cellular and/or gene expression level, and will eventually induce "cellular memory due to pain", which means that tissue damage, even if only transient, can elicit epigenetically abnormal transcription/translation and post-translational modification in related cells depending on the degree or kind of injury or associated conditions. Such cell memory/transformation due to pain can cause an abnormality in a fundamental intracellular response, such as a change in the three-dimensional structure of DNA, transcription, or translation. On the other hand, pain is a multidimensional experience with sensory-discriminative and motivational-affective components. Recent human brain imaging studies have examined differences in activity in the nucleus accumbens between controls and patients with chronic pain, and have revealed that the nucleus accumbens plays a role in predicting the value of a noxious stimulus and its offset, and in the consequent changes in the motivational state. In this review, we provide a very brief overview of a comprehensive understanding of chronic pain associated with emotional dysregulation due to transcriptional regulation, epigenetic modification and miRNA regulation.

    The aim was to analyze the rate of sudden death in elderly Croatian women in comparison to elderly Croatian men, who died suddenly due to swimming. In the period from 2002 to 2011 one elderly Croatian woman and five elderly men died suddenly during swimming. In the same time, the same number of elderly foreigners died due to swimming at the Croatian Adriatic coast. One Croatian woman aged 66, who suffered of arterial hypertension with left ventricular hyper- trophy of 15 mm, diabetes mellitus and alcoholic liver cirrhosis, drowned in the sea during swimming. She was intoxi- cated with alcohol and had alcohol level in urine of 3.03 per thousand. One foreign woman, aged 82, who suffered coronary heart disease with left ventricular scar after myocardial infarction, arterial hypertension with excessive left ventricular hypertrophy of 22 mm and nephroangiosclerosis, suddenly lost conscionsness during swimming. The death rate in elderly Croatian women due to swimming reached 0.25, and the death rate in men is eight times higher: 1.97 (p = 0.0701), but the difference is not significant probably because of a small observational number.

    Retrospective analysis of civilians with spinal cord injuries (SCIs) due to terror explosions. To analyze and describe the clinical characteristics and rehabilitation outcomes of civilians with SCI due to explosions admitted for in-patient rehabilitation from 2000-2004. SCI rehabilitation service, Tel Hashomer, Israel. Retrospective chart review. Civilians with SCI due to terror-related gunshot wounds (GSWs) served as a control group. Eleven civilians with SCI caused by penetrating atypical foreign objects (PAFOs) and eight with GSWs were identified. The male-to-female ratio was approximately 2:1. Foreign objects were present within the spinal canal in seven patients, causing bone injury without canal penetration in three, and one patient had both bone injury and canal penetration. The most common level of injury was thoracic. Seven had complete motor SCI. Three individuals improved in American Spinal Injury Association status: one individual improved from B to C (cervical); one from C to D (thoracic); and the third from D to E (lumbar). Despite the similar acute hospital length of stay and functional independence measure (FIM) scores on admission, the PAFO group had a shorter rehabilitation length of stay with higher FIM scores and higher FIM efficiency at discharge. Although the pathophysiology of PAFO blast injuries is similar to the high-velocity GSWs or the high-energy military munition injuries, better rehabilitation outcomes were seen, with slightly higher FIM efficiency and efficacy at discharge. This result is likely to be caused by less neurological tissue damage at impact.

    Deaths due to plastic bag suffocation or plastic bag asphyxia are not reported in Malaysia. In the West many suicides by plastic bag asphyxia, particularly in the elderly and those who are chronically and terminally ill, have been reported. Accidental deaths too are not uncommon in the West, both among small children who play with shopping bags and adolescents who are solvent abusers. Another well-known but not so common form of accidental death from plastic bag asphyxia is sexual asphyxia, which is mostly seen among adult males. Homicide by plastic bag asphyxia too is reported in the West and the victims are invariably infants or adults who are frail or terminally ill and who cannot struggle. Two deaths due to plastic bag asphyxia are presented. Both the autopsies were performed at the University Hospital Mortuary, Kuala Lumpur. Both victims were 50-year old married Chinese males. One death was diagnosed as suicide and the other as sexual asphyxia. Sexual asphyxia is generally believed to be a problem associated exclusively with the West. Specific autopsy findings are often absent in deaths due to plastic bag asphyxia and therefore such deaths could be missed when some interested parties have altered the scene and most importantly have removed the plastic bag. A visit to the scene of death is invariably useful.

    We report 4 cases of pseudothrombocytopenia due to platelet cold agglutinins. Case 1 was a 57 y.o. female whose platelet count was 97 x 10(3)/microl. Case 2 was a 37 y.o. male with a platelet count of 96 x 10(3)/microl. Case 3 was a 74 y.o. male with a platelet count of 28 x 10(3)/microl. Case 4 was a 62 y.o. female whose platelet count was 34 x 10(3)/microl. The platelet counts in these 4 cases were decreased and blood smears showed platelet clumping in blood drawn in a tube without anticoagulant just after withdrawal, as well as in blood drawn in a tube with anticoagulant. The platelets from these patients agglutinated at a temperature below 10 degrees C (case 1 and 4) and 24 degrees C (case 2). The immunoglobulin class of the platelet cold agglutinins in cases 1, 2 and 4 was IgM. Agglutinated platelets showed no activation marker, such as CD62P, CD63 or CD40L, on the surface of the platelets. The target antigen of cold agglutinins was GPIIb-IIIa in cases 1 and 2. We considered that the detection of platelet agglutination in blood without anticoagulant is important to diagnose pseudothrombocytopenia due to platelet cold agglutinins. Although this disease is considered to be very rare, we suspect that this disease may be misdiagnosed as pseudothrombocytopenia due to the presence of an anticoagulant, and overlooked.

    Full Text Available Objective: To analyze the incidence and the length of periods off work specifically linked to psychological causes among nursing professionals. Furthermore, the study tried to identify risk factors for the work leaves and suggest actions that can mitigate the problems encountered. Methods: This was a retrospective, ecological study, in the largest public hospital of Curitiba-PR, with data from 3,692 nurses (2,294 auxiliary nurses, 590 nursing technicians and 808 nurses from January 2007 to September 2010. An exploratory review was performed to form the theoretical basis of this study. The annual incidences for each type of work leave due to psychological causes were identified, among the nursing professionals. Results: It was found that the main cause of absenteeism were depressive episodes (F32, with 784 leaves. As for the length of time, the cause for longer periods off among nurses (40.62 days on average was the bipolar affective disorder (F31. Nursing assistants and technicians were away from work due to recurrent depressive disorder (F33 on average for 40.47 days and 54.33 days, respectively. Conclusion: There was a high incidence of depressive episodes and the mean duration of absenteeism due to psychological causes was over 30 days, pointing to the need of investments in prevention and in healthcare for nursing professionals. doi:http://dx.doi.org/10.5020/18061230.2013.p554

    Two experiments contrast the effects of fluency due to repetition and fluency due to color contrast on judgments of truth, after participants learn to associate high levels of fluency with falseness (i.e., a reversal of the fluency-truth link). Experiment 1 shows that the interpretation of fluency as a sign of truth is harder to reverse when learning is promoted with repetition rather than with perceptual fluency. Experiment 2 shows that when color contrast and repetition are manipulated orthogonally, the reversal of the truth effect learned with color contrast does not generalize to repetition. These results suggest specificities in the processing experiences generated by different sources of fluency, and that their influences can be separated in contexts that allow the contrast of their distinctive features. We interpret and discuss these results in light of the research addressing the convergence vs. dissociation of the effects elicited by different fluency sources.

    Introduction: Septic olecranon bursitis due to atypical mycobacteria is rare. An insidious beginning can delay diagnosis and treatment. Antibacterial therapy recommendations are not well-defined for bursitis caused by atypical mycobacteria. We present a rare case of olecranon bursitis caused by Mycobacterium gordonae, reporting our experiences regarding pathogen identification and antibiotic therapy, which differs from regimes used in common septic bursitis mostly caused by staphylococcus aureus. Methods: A 35-year-old male with bursitis olecrani received open bursectomy. Microbiological culture did not reveal bacteria. Due to wound healing complications revision surgery was performed four weeks postoperatively. Finally, Mycobacterium gordonae was identified by PCR and an antibiogram could be developed. A triple antimicrobial combination therapy with Rifampicin, Clarithromycin, and Ethambutol was administered systemically for 12 months. The patient was followed-up for 24 months. Results: After the second operation with pathogen identification and antibiotic combination therapy the wound healed without any additional complications. At last follow-up 24 months after the first surgery with bursectomy and 23 months after revision surgery with debridement, the patient was still pain free with no significant clinical findings or tenderness to touch at the operation site. Elbow range of motion was full. Discussion: As septic bursitis can be caused by many different and sometimes rare and difficult to identify bacteria, intraoperative probes should be taken and histopathological and microbiological analysis should be conducted, including PCR. In a young man with olecranon bursitis due to Mycobacterium gordonae surgical treatment and an antibiotic combination therapy showed a good clinical outcome after one and two years. PMID:27892398

    Context. For photoionized plasmas, electron energy loss rates due to radiative recombination (RR) are required for thermal equilibrium calculations, which assume a local balance between the energy gain and loss. While many calculations of total and/or partial RR rates are available from the literature, specific calculations of associated RR electron energy loss rates are lacking. Aims: Here we focus on electron energy loss rates due to radiative recombination of H-like to Ne-like ions for all the elements up to and including zinc (Z = 30), over a wide temperature range. Methods: We used the AUTOSTRUCTURE code to calculate the level-resolved photoionization cross section and modify the ADASRR code so that we can simultaneously obtain level-resolved RR rate coefficients and associated RR electron energy loss rate coefficients. We compared the total RR rates and electron energy loss rates of H i and He i with those found in the literature. Furthermore, we utilized and parameterized the weighted electron energy loss factors (dimensionless) to characterize total electron energy loss rates due to RR. Results: The RR electron energy loss data are archived according to the Atomic Data and Analysis Structure (ADAS) data class adf48. The RR electron energy loss data are also incorporated into the SPEX code for detailed modeling of photoionized plamsas.

  9. Meningococco B: controllo di due focolai epidemici mediante vaccinazione

    Science.gov (United States)

    2014-01-01

    Riassunto La problematica di un efficace approccio vaccinale nei confronti del Meningococco B (MenB) è stata superata identificando con la metodica della "reverse vaccinology" alcuni antigeni capaci di indurre una risposta verso la maggior parte dei ceppi di MenB circolanti nel mondo. Il nuovo vaccino MenB a 4 componenti (4CMenB) è stato autorizzato in Europa, Australia e Canada, ed è entrato nei calendari di immunizzazione pediatrica internazionali: Australia, Canada, UK. In Italia, le prime regioni che hanno raccomandato la vaccinazione contro il MenB sono state Basilicata e Puglia. La gestione di epidemie/focolai epidemici richiede la messa in atto di una risposta rapida da parte delle autorità sanitarie nei confronti di una emergenza sanitaria ad elevato impatto, anche emotivo, sulla popolazione, come recentemente dimostrato in due università americane. Alla dichiarazione di focolaio epidemico in atto, in entrambi i contesti si è attivata una procedura per l'uso del vaccino 4CMenB non ancora autorizzato negli USA. È stato così possibile organizzare gli interventi di profilassi attiva nei due campus universitari, adottando il primo impiego su larga scala del nuovo vaccino 4CMenB e conseguendo, in tempi relativamente brevi, elevati tassi di copertura vaccinale. A fronte di circa 14000 studenti immunizzati con almeno una dose, non è stata segnalata alcuna problematica di eventi avversi conseguenti all'immunizzazione; ad oggi non si sono verificati casi nei soggetti che hanno ricevuto il vaccino. Come conseguenza dei due focolai descritti, è oggi in corso la valutazione da parte dell'FDA per l'estensione dell'uso del vaccino 4CMenB negli Stati Uniti negli adolescenti e giovani adulti.

    Introduction Female sex workers (FSWs) are at high risk of HIV infection. Our objective was to determine the proportion of HIV prevalence in the general female adult population that is attributable to the occupational exposure of female sex work, due to unprotected sexual intercourse. Methods Population attributable fractions of HIV prevalence due to female sex work were estimated for 2011. A systematic search was conducted to retrieve required input data from available sources. Data gaps of HIV prevalence in FSWs for 2011 were filled using multilevel modeling and multivariate linear regression. The fraction of HIV attributable to female sex work was estimated as the excess HIV burden in FSWs deducting the HIV burden in FSWs due to injecting drug use. Results An estimated fifteen percent of HIV in the general female adult population is attributable to (unsafe) female sex work. The region with the highest attributable fraction is Sub Saharan Africa, but the burden is also substantial for the Caribbean, Latin America and South and Southeast Asia. We estimate 106,000 deaths from HIV are a result of female sex work globally, 98,000 of which occur in Sub-Saharan Africa. If HIV prevalence in other population groups originating from sexual contact with FSWs had been considered, the overall attributable burden would probably be much larger. Discussion Female sex work is an important contributor to HIV transmission and the global HIV burden. Effective HIV prevention measures exist and have been successfully targeted at key populations in many settings. These must be scaled up. Conclusion FSWs suffer from high HIV burden and are a crucial core population for HIV transmission. Surveillance, prevention and treatment of HIV in FSWs should benefit both this often neglected vulnerable group and the general population. PMID:23717432

    2006-01-01

    We investigate the contribution of extra dimensions to muon anomalous magnetic moment using a 6-dimensional model. The approach analyzes the extent to which small brane fluctuations influence the magnetic moment. In particular, we assume that the fluctuations are static in time, which add the new potential terms to the schr{\\"o}dinger equation through the induced vierbein. This paper shows that the fluctuations result in the brane stretching effect due to the negative tension. The effect would be a capable of reproducing the appropriate order for the recent BNL measurements of the muon (g-2) deviation.

    2004-01-01

    A representation for the velocity and pressure fields in three-dimensional Stokes flow was presented in terms of a biharmonic function A and a harmonic function B. This representation was used to establish a general theorem for the calculation of Stokes flow due to fundamental singularities in a region bounded by a stationary no-slip plane boundary.Collins' s theorem for axisymmetric Stokes flow before a rigid plane follows as a special case of the theorem. A few illustrative examples are given to show its usefulness.

    Full Text Available Opportunistic subcutaneous fungal infections are increasing nowadays due to the growing number of medical conditions causing immunosuppression, especially organ transplant. The incidence rate of subcutaneous phaeohyphomycosis is very low. Most studies found are case reports. They showed a wide variation of clinical presentations. Pyrenochaeta romeroi, a fungus from the Dematiaceae group is a saprophyte found in soil and plants and a possible causative agent of phaeohyphomycosis. We present a rare case of subcutaneous phaeohyphomycosis caused by P. romeroi mimicking a synovial cyst in a diabetic patient.

    Full Text Available The volume expansion of tantalum due to the dissolved hydrogen has been determined using Bragg equation. The hydrogen was dissolved in the pure tantalum metal at constant temperature (360 °C and constant pressure (132 mbar by varying the duration of hydrogen charging. The amount of dissolved hydrogen was within the solid solubility limit. The samples with different hydrogen concentration were analyzed by X-ray diffraction technique. Slight peak shifts as well as peak broadening were observed. The relative changes of lattice parameters plotted against the hydrogen concentration revealed that the lattice parameters varied linearly with the hydrogen concentration.

    2003-01-01

    Full Text Available Injection abscess is an iatrogenic infection occurring as an isolated case or as cluster outbreak. These infections occur due to contaminated injectables or lapse in sterilisation protocol. While pathogens such as Pseudomonas, Klebsiella, E. coli, and S. aureus are the usual causative agents, unusual organisms such as mycobacteria, particularly the rapidly growing non-tuberculous mycobacteria (NTM may cause the abscess. The chances of overlooking these organisms is high unless an acid fast bacilli (AFB smear and culture is done on all aspirated pus specimens. We report a case of a three year old child who presented with a gluteal abscess following an intramuscular infection with an unknown preparation.

    Scombroid fish poisoning, one of the most common adverse reactions to fish, is also probably one of the most common causes of a flushing syndrome. The reaction usually involves fishes of the Scombridae family but, in Hawaii, the reaction is most often due to mahimahi (Coryphaena hippurus). Onset of the reaction is usually abrupt and commonly associated with a prominent flush resembling a sunburn. Headache, tachye to a toxin with histamine-like properties, which is formed because improper refrigeration enables endogenous bacteria to decarboxylate histidine normally present in dark-meat fishes. Symptoms are usually promptly relieved by parenteral antihistamine therapy.

    Full Text Available We report a case of chronic meningitis due to Mycobacterium chelonae. This organism is a rapidly growing Mycobacterium (RGM and can be found worldwide in environmental sources such as soil, dust, and water. M. chelonae is an uncommon cause of meningitis; the majority of infections caused by this organism are localized cutaneous or soft tissue infections, and rarely lung infections. The organism is indistinguishable phenotypically, so we applied PCR based on the rpoB gene sequence followed by restriction fragment length polymorphism (RFLP for molecular identification. The subsequent sequencing of RFLP products revealed 99.7% similarity with M. chelonae.

    We consider the Korteweg-de Vries (KdV) and nonlinear Schrodinger (NS) equations with higher-order derivative terms describing dispersive corrections. Conditions of existence of stationary and radiating solitons of the fifth-order KdV equation are obtained. An asymptotic time-dependent solution...... to the latter equation, describing the soliton radiation, is found. The radiation train may be in front as well as behind the soliton, depending on the sign of dispersion. The change rate of the soliton due to the radiation is calculated.

    2015-10-01

    Patients with shunted hydrocephalus presenting with altered mental status and ventriculomegaly are generally considered to be in shunt failure requiring surgical treatment. The authors describe a case of shunted hydrocephalus secondary to a disseminated neuroectodermal tumor in a pediatric patient in whom rapid fluctuations in sodium levels due to diabetes insipidus repeatedly led to significant changes in ventricle size, with invasively confirmed normal shunt function and low intracranial pressure. This clinical picture exactly mimics shunt malfunction, requires urgent nonsurgical therapy, and underscores the importance of considering serum osmolar abnormalities in the differential diagnosis for ventriculomegaly.

    Full Text Available Cow′s milk protein allergy (CMPA typically presents with persistent diarrhea or dysentery, vomiting and bleeding per rectum in young infants. CMPA is reported to mimic Hirschsprung′s disease and malrotation. We report, a neonate who presented with recurrent attacks of segmental enteritis due to CMPA and the last episode presented with signs of peritonitis. He improved dramatically after elimination of cow′s milk from his diet. CMPA should be considered in artificially fed babies with surgical abdomen and atypical clinical signs and symptoms.

    Full Text Available An infant presented with clinical signs and symptoms suggestive of a pyloric stenosis. On abdominal ultrasound, pyloric stenosis was excluded, and other causes for proximal duodenal obstruction, such as a duodenal web or annular pancreas, were suspected. At surgery, the cause was found to be due to an anterior portal vein or preduodenal portal vein, compressing the duodenum. There were no associated findings such as midgut malrotation, duodenal web and congenital anomalies. The treatment was a diamond-shaped duodeno-duodenostomy anterior to the portal vein. The patient improved after surgery.

    2012-01-01

    Full Text Available One of the agents that cause dystonic reactions is metoclopramide. In this study, we presented three individuals of the same family who were admitted to our hospital while receiving the treatment of metoclopramide because of developing acute dystonic reaction. Appropriate doses of metoclopramide therapy had begun to all brothers with a diagnosis of gastroenteritis. After receiving the first dose of medication, acute dystonia was observed within half an hour in these brothers who used metoclopramide. Thus, if there is a patient who developed acute dystonia in the same family due to metoclopramide, avoiding from use of metoclopramide will be beneficial for other members of the family.

    Full Text Available We report a case of postoperative wound infection due to Mycobacterium chelonae. A 35-year-old woman presented with multiple erythematous nodules, plaques and discharging sinuses over the abdomen, 45 days after she had undergone laparoscopic ovarian cystectomy. The seropurulent discharge from the wound showed acid-fast bacilli on Ziehl- Neelsen stain and culture yielded Mycobacterium chelonae . The patient responded to clarithromycin and doxycycline. The source of infection was probably contaminated water or disinfectant solution used for sterilization of laparoscopic instruments.

    A subarachnoid haemorrhage (SAH) occurred 67 days after cardiac transplantation in 10-year-old girl with consecutive immunocompromising therapy. Neither digital subtraction angiography (DSA) nor computed tomographic angiography showed signs of intracranial vascular malformations. One month before the lethal SAH occurred, she had developed arterial hypertension and attacks of severe headache with cerebrospinal fluid (CSF) pleocytosis while CT scans showed an infarct of the left thalamus. Pathologic findings established the rare diagnosis of SAH due to aspergillosis-related mycotic arteritis. Imaging characteristics are presented. (orig.)

    Purpose An evaluation of mortality due to infectious diseases in Poland in 1999–2012 and an analysis of standard expected years of life lost due to the above diseases. Methods The study material included a database created on the basis of 5,219,205 death certificates of Polish inhabitants, gathered between 1999 and 2012 and provided by the Central Statistical Office. Crude Death Rates (CDR), Standardized Death Rates (SDR) and Standard Expected Years of Life Lost (SEYLL) due to infectious and parasitic diseases were also evaluated in the study period as well as Standard Expected Years of Life Lost per living person (SEYLLp) and Standard Expected Years of Life Lost per dead person (SEYLLd). Time trends were evaluated with the application of joinpoint models and an annual percentage change in their values. Results Death certificates report that 38,261 people died due to infectious diseases in Poland in the period 1999–2012, which made up 0.73% of the total number of deaths. SDR caused by these diseases decreased, particularly in the male group: Annual Percentage Change (APC = -1.05; 95% CI:-2.0 to -0.2; p<0.05). The most positive trends were observed in mortality caused by tuberculosis (A15-A19) (APC = -5.40; 95% CI:-6.3 to -4.5; p<0.05) and also meningitis, encephalitis, myelitis and encephalomyelitis (G03-G04) (APC = -3.42; 95% CI:-4.7 to -2.1; p<0.05). The most negative mortality trends were observed for intestinal infectious diseases (A00-A09) Annual Average Percentage Change (AAPC = 7.3; 95% CI:3.1 to 11.7; p<0.05). SDR substantially decreased in the first half of the study period, but then significantly increased in the second half. Infectious and parasitic diseases contributed to a loss of around 37,000 standard expected years of life in 1999 and more than 28,000 in 2012. During the study period, the SEYLLp index decreased from 9.59 to 7.39 per 10,000 population and the SEYLLd index decreased from 14.26 to 10.34 years (AAPC = 2.3; 95% CI:-2,9 to -1.7; p<0

  10. Limitations on plasma acceleration due to synchrotron losses

    1999-01-01

    In this letter we consider the effect of synchrotron radiation losses due to the betatron motion of the electron beam in its self-induced magnetic field in a plasma accelerator taking into account the charge neutralization factor. The most favorable case is where the plasma density is smaller than the beam density. The contrary regime is strongly disfavored by the synchrotron radiation loss for beams with characteristics for TeV energies. In both cases we find that upon increasing the plasma density the synchrotron losses kill the acceleration process, so that there are limitations on the maximum allowable plasma density.

    In recent years, the use of herbal medicine by the general population is increasing. There are many known side effects resulting from these treatments. Despite the known side effects, physicians tend to neglect the anamnesis details regarding this issue and research budgets of these drugs are relatively low compared with conventional medicine, thus causing a lack of updated information. In this case report, we present an example of toxic hepatitis due to use of Ruta herbal medicine, an unfamiliar side effect of the common herbal medicine Ruta.

    Abstract Lyme neuroborreliosis (LNB) is a rare cause of vasculitis and stroke. It may manifest as subarachnoid hemorrhage, intracerebral hemorrhage, and most often ischemic stroke due to cerebral vasculitis. The vast majority of reported cases have been described by European authors. A high index of suspicion is required in patients who live or have traveled to areas with high prevalence of tick-borne diseases, and in the case of stroke-like symptoms of unknown cause in patients without cardiovascular risk factors. In this review, we also present four illustrative cases of vasculitis and stroke-like manifestations of LNB.

    We report the case of a 20-year-old Japanese woman with no psychiatric history with apparent dissociative symptoms. These consisted of amnesia for episodes of shoplifting behaviors and a suicide attempt, developing together with an exacerbation of Graves' hyperthyroidism. Patients with Graves' disease frequently manifest various psychiatric disorders; however, very few reports have described dissociative disorder due to this disease. Along with other possible causes, for example, encephalopathy associated with autoimmune thyroid disease, clinicians should be aware of this possibility. Copyright © 2014 Elsevier Inc.

    An investigation on damage location due to the corrosion in reinforced concrete structures is conducted. The frequency change square ratio is used as a parameter for the damage. It is theoretically verified that the parameter is a function of the damage location. Experimental results of the corrosion in reinforced concrete structures show that the predicted damage location is in agreement with the real damage location. The modal parameters are used to detect the damages in structural concrete elements, and so they are useful for structural appraisal.

    A 61-year-old man with gigantism and acromegaly choked and fell into a coma. Immediate tracheal intubation resulted in a return of his consciousness. Enhanced computed tomography indicated that the trachea and left main bronchus were compressed by the thoracic spine and sternum. He required tracheotomy and positive end-expiratory pressure to maintain his pulmonary function. This is the first case of suffocation due to a thoracic deformity associated with acromegaly. Physicians should focus on clearing the tracheal airway using computed tomography to elucidate the anatomical relationship between the trachea and surrounding structures in acromegalic patients suffering from dyspnea.

    Full Text Available We present the case of a patient with previous psychiatric illness, acutely exacerbated by thyroid storm due to Graves’ disease, in whom treatment with antipsychotics induced catatonia. These associations are extremely rare and may be confused with Hashimoto’s encephalopathy, especially in the presence of anti-thyroid antibodies in cerebrospinal fluid. The treatment consists in the control of the triggering disease (in this case the resolution of the thyrotoxicosis and the use of benzodiazepines. However, in some cases, the resolution of psychiatric symptoms is partial and may require the use of electroconvulsive therapy.

    Soft tissue infection due to Mycobacterium tuberculosis can affect muscle, tendons, fascia, bursa and synovial tissue. Tuberculous trochanteric bursitis is a rare entity that usually affects immunocompromised patients. Manifestations usually occur insidiously, which delays diagnosis and treatment. We present the case of an immunocompetent young woman who came to our department for chronic left hip pain. The study confirms the diagnosis of tuberculous trochanteric bursitis. This case demonstrates the importance of considering a possible infectious origin of bursitis in immunocompetent patients. Copyright © 2010 Elsevier España, S.L. All rights reserved.

    2016-06-01

    Wavenumber shift of the ion Bernstein wave has been observed in the particle-in-cell simulations when the input power of the injected wave is sufficiently large. It is demonstrated that the increase of the total kinetic energy of ions, including both the thermal energy related to the random thermal motion and the oscillation energy due to the coherent motion with the wave, gives rise to such change of the wavenumber. However, the velocity distribution function of the ions can approximately be fitted as a Maxwellian distribution function, and thus, the linear dispersion relation still holds, provided that the initial ion temperature is replaced by the effective temperature measured in the simulation.

    2007-02-01

    Full Text Available We report a case history of an 84-year-old elderly male patient that presented with a clinical picture suggestive of adrenal failure and bilateral adrenal nodules detected by abdominal computed tomography. A fine needle-guided biopsy was inconclusive for achieving a final diagnosis. The patient died due to septic shock and the autopsy disclosed histoplasmosis with extensive bilateral necrosis of the adrenal glands. Although the adrenal involvement in chronic disseminated histoplasmosis has been described, there have been few reports of the infection being associated with adrenal insufficiency.

  5. Intramolecular vibrational dynamical barrier due to extremely irrational couplings

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The intramolecular vibrational dynamics due to extremely irrational couplings is demonstrated by contrast to the resonance couplings, for the three-mode case of H2O as an example. The extremely irrational couplings are shown to impose such strong hindrance to intramolecular vibrational relaxation (IVR) that they act as barriers. They restrict the direct action/energy transfer between the two stretching modes, though they allow the transfer between a stretching and a bending modes. In contrast, the resonance is more mediated by the bending mode and leads to chaotic IVR. It is also shown that there is a region in the dynamical space in which resonance and extremely irrational couplings coexist.

  6. Trigeminal hypoplasia due to vertebrobasilar dolichoectasia: A new entity

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The term "vertebrobasilar dolichoectasia" refers to anomalous dilatation of the intracranial arteries associated with elongation or tortuosity of the affected vessels. The etiology of the disease is unknown and is usually detected incidentally. The predominant clinical manifestations arise due to the mass effect of the dilated vessels and may include cranial nerve compression, extrinsic aqueductal compression, motor and sensory disturbances. Trigeminal hypoplasia is a very uncommon condition, usually described in association with Goldenhar-Gorlin syndrome and has not yet been attributed to vertebrobasilar dolichoectasia. The current case report highlights this rare association of trigeminal nerve hypoplasia and vertebrobasilar dolichoectasia, leading to hemifacial and corneal anesthesia.

    Full Text Available Aim:Childhood injuries are the leading cause of death in children and result in significant healthcare utilization. Trauma is the second most common cause of mortality in children aged 1-4 years and leading cause of death in children older than 4 years. Thoracic injury is the second most leading cause of death in traumatized children. Multisystemic injury is found in more than 50% of children with thoracic injuries most of which are secondary to blunt traumas. We planned this study to evaluate thorax trauma cases secondary to bicycle driving in childhood and to draw attention to the importance of the regulation of traffic rules, the education of bicycle drivers.Material and Methods:  A retrospective evaluation was performed in 17 pediatric patients admitted to the Department of Thoracic Surgery during 2006-2010 with a diagnosis of chest trauma due to bicycle driving. For every patient, a pediatric trauma score (PTS was calculated. Descriptive statistics were performed for PTS. Results; Eleven (64.70% cases were injured due to the tricycle accidents and six cases 6 (35.29% were injured due to the two-wheeled bicycle accidents. The most frequent thoracic pathologies included pulmonary contusion (41.2% and chest wall contusion (29.41%. Extrathoracic injuries were seen in 35.29%, the extremities (17.64% and abdomino pelvic (11.76% being the most commonly involved. Treatment consisted of symptomatic treatment in 12 patients (70.58%, tube thoracostomy in 2 patients (11.76%, and thoracotomy in 1 patient (5.9%. The morbidity was seen in 3 patients (17.64%. The mortality rate was 5.9% (n:1. The mean PTS of the cases who had additional system injuries were significantly worse than the cases who had isolated chest traumas Conclusions: The pediatric thorax has a greater cartilage content and incomplete ossification of the ribs. Due to the pliability of the pediatric rib cage and mediastinal mobility, significant intrathoracic injury may exist in the

  11. Acute colonic obstruction due to benign prostatic hypertrophy.

    Mac Giobuin, S

    2012-02-01

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

    A small epidemic of tinea corporis due to M. gypseum is reported. There were 13 children affected, ages 1-15 years. These children belonged to 6 neighbouring families and all used a common "playground", an empty lot located nearby. Cultures were positive for M. gypseum in the 13 children and the agent was also isolated from 2 soils collected in the playing-ground. Soil isolates were classified as N. gypsea. Clinically, the lesions were circinated and had active borders, they were preferentially located in the trunk. Most children (8/13) had multiple lesions. These and other pertinent aspects are discussed in the text.

    Irritation of the tendon of the musculus iliopsoas after total hip replacement is a rare complication. In connection with the irritation of the iliopsoas tendon only one case report of a psoas haematoma due to anticoagulation has been published. We assume that these kinds of haematomas are more frequent than described. We report on 2 cases of haematoma caused by an iliopsoas impingement after total hip replacement. In one case a lesion of the femoral nerve was observed. Surgical treatment was composed of the revision of the acetabular component. Georg Thieme Verlag KG Stuttgart · New York.

    Introduction: Citrobacter koseri is a gram-negative bacillus that rarely causes infection in immunocompetent hosts and typically is associated with urinary or respiratory tract infections. Rarely will Citrobacter be a cause of infective endocarditis. Case Report: We present a case of a 77-year-old man with no known immunocompromising conditions who was hospitalized for infective aortic endocarditis due to Citrobacter koseri originating from a chronically infected prostate. Unusually, he also developed a C. koseri diskitis and phlegmon, which, along with the aortic vegetations, increased in size despite appropriate antibiotics. The patient thus met indications for aortic valve replacement and had improved appearance of lesions in follow-up imaging.

    2003-10-01

    A very early and severe case of maxillary incisor resorption caused by impacted canines is reported. An estimated 50,000 cases of ectopic eruption and impaction of maxillary canines occur each year in the United States. Although incisor resorption due to ectopically positioned permanent maxillary canines can be swift, silent, and devastating, an effective protocol has been developed for early detection and management of this condition. Palpation and, if indicated, radiographic evaluation are combined with primary canine removal in selected cases. These strategies--particularly when used early--can prevent the vast majority of palatally impacted maxillary canines and the potentially devastating resorption of adjacent incisors.

The fatigue life is dependent on the number, type, location and size of the defects in the component and is therefore quite uncertain and needs to be described by stochastic models. In this paper, the Poisson distribution for modeling of defects...... of component are considered and the surface and sub-surface defects categorized. Furthermore, a model to estimate the probability of failure by fatigue due to the defects is proposed. This model is used to estimate the failure location of component and it is compared to models of defect distributions...

    2017-02-01

    The possibility of observing many-body localization of ultracold atoms in a one-dimensional optical lattice is discussed for random interactions. In the noninteracting limit, such a system reduces to single-particle physics in the absence of disorder, i.e., to extended states. In effect, the observed localization is inherently due to interactions and is thus a genuine many-body effect. In the system studied, many-body localization manifests itself in a lack of thermalization visible in temporal propagation of a specially prepared initial state, in transport properties, in the logarithmic growth of entanglement entropy, and in statistical properties of energy levels.

    When an electron bunch is compressed in a chicane compressor,the CSR (coherent synchrotron radiation) will induce energy redistribution along the bunch.Such energy redistribution will affect the longitudinal emittance as a direct consequence.It will also excite betatron oscillation due to the chromatic transfer functions,and hence a transverse emittance change.So,it is indispensable for us to find a way to alleviate the CSR-cansed emittance dilution and the bad result of chicane compressor in PKU-FEL.

    Fresnel lenses are widely used in concentrating photovoltaic (CPV) systems as a primary optical element. They focus sunlight on small solar cells or on the entrance apertures of secondary optical elements. A Fresnel lens consists of several prism rings and diffraction by these prism rings is unavoidable. Some of the light that would reach a designated target area according to geometric optics will miss it due to diffraction. This diffraction loss may be of relevant magnitude for CPV applications. The results of published analytical calculations are evaluated, discussed, and compared to computer simulations and measurements.

    Given that terrestrial medical practices must be used as the basis for drug choice and use on missions, there is a possibility that medications used will be ineffective or inappropriate for the actual circumstances encountered on missions. Because the human body undergoes a variety of physiological changes during spaceflight, there is a risk that terrestrial medications may not perform as expected when used during spaceflight. Alterations in physiology due to spaceflight could result in unexpected drug action on the body (pharmacodynamics) or in unusual drug absorption, distribution, metabolism or excretion (pharmacokinetics). The spaceflight environment may also have direct effects on stored drugs themselves, leading to premature inactivation or degradation of stored drugs.

    Full Text Available Temporary henna tattoos have become very popular among children and teenagers in recent years. However, the use of additives to shorten the application time and darken the color of commercial henna, such as para-phenylenediamine, has led to an increased risk of complications due to those tattoos. The most commonly seen complications are allergic contact dermatitis, hypertrophic scarring, keloid formation, hyperpigmentation, and hypopigmentation. Herein; a 13-year-old girl who developed localized hypertrichosis after a temporary henna tattoo application was presented.

    Cassava rootstocks of varieties UnB 201 and UnB 122 grafted with scions of Manihot fortalezensis were prepared for anatomic study. The roots were cut, stained with safranin and alcian blue, and examined microscopically, comparing them with sections taken from ungrafted roots. There was a significant decrease in number of pericyclic fibers, vascular vessels and tyloses in rootstocks. They exhibited significant larger vessels. These changes in anatomic structure are a consequence of genetic effects caused by transference of genetic material from scion to rootstock. The same ungrafted species was compared. This is the first report on anatomic changes due to grafting in cassava.

    Uterine leiomyoma (UL) is the most common benign gynecologic tumor of the reproductive age females. It is symptomatic only in 25% of the patients causing dysmenorrhea, menorrhagia or anemia. In some patients it occurs just as a palpable abdominal mass. In this study, we report a 50-year-old woman with a giant mass, attached to the uterus, which was detached and therefore led to shock due to major hemorrhage. Surgical removal of both the mass and the uterus confirmed the diagnosis of a pedunculated uterine leiomyoma.

    Full Text Available Hyperthyroidism is one of the most common causes of cardiac failure. Blood volume expands greatly during pregnancy, especially after the last part of the second trimester. Such expansion exacerbates the symptoms of heart failure and accelerates the development of pulmonary edema when abnormal thyroid function is not well controlled. Two cases of pregnancy complicated with congestive heart failure and pulmonary edema due to hyperthyroidism are reported here. Both patients did not receive treatment for hyperthyroidism during pregnancy, and both sought clinical help during the third trimester. The clinical problems were resolved by medical management before delivery.

    An infected aortic aneurysm, or mycotic aneurysm, is a rare arterial dilatation due to destruction of the infected vessel wall. Common pathogens resulting in an infected aortic aneurysm are Salmonella and Clostridium species, as well as Staphylococcus aureus; Morganella morganii, on the other hand, is very rare. An infected abdominal aortic aneurysm has tendencies to grow rapidly and to rupture. The mortality rate is high in patients undergoing emergent surgical intervention. We report the case of a 65-year-old man who presented with an infected abdominal aortic aneurysm caused by M. morganii. A high index of suspicion and imaging tests are necessary in order to diagnose an infected aortic aneurysm.

  14. Seismic attenuation due to wave-induced flow

    Energy Technology Data Exchange (ETDEWEB)

    Pride, S.R.; Berryman, J.G.; Harris, J.M.

    2003-10-09

    Analytical expressions for three P-wave attenuation mechanisms in sedimentary rocks are given a unified theoretical framework. Two of the models concern wave-induced flow due to heterogeneity in the elastic moduli at mesoscopic scales (scales greater than grain sizes but smaller than wavelengths). In the first model, the heterogeneity is due to lithological variations (e.g., mixtures of sands and clays) with a single fluid saturating all the pores. In the second model, a single uniform lithology is saturated in mesoscopic ''patches'' by two immiscible fluids (e.g., air and water). In the third model, the heterogeneity is at ''microscopic'' grain scales (broken grain contacts and/or micro-cracks in the grains) and the associated fluid response corresponds to ''squirt flow''. The model of squirt flow derived here reduces to proper limits as any of the fluid bulk modulus, crack porosity, and/or frequency is reduced to zero. It is shown that squirt flow is incapable of explaining the measured level of loss (10{sup -2} < Q{sup -1} < 10{sup -1}) within the seismic band of frequencies (1 to 10{sup 4} Hz); however, either of the two mesoscopic scale models easily produce enough attenuation to explain the field data.

    AlphaCor keratoprosthesis (KPro) is a new-concept poly (2-hydroxyethyl methacrylate) one-piece KPro that makes possible a two-step implantation technique easy to perform with a short learning curve. In literature an 18% incidence of AlphaCor removal due to melting complications is reported. The histopathology of corneal tissue removed during a re-operation while bearing an AlphaCor KPro has previously been described in the literature only in one report. Herein, the first histological features of an AlphaCor-corneal complex explanted because of KPro extrusion is described. The histopathology of the AlphaCor-corneal complex is characterized by mild inflammation in the corneal tissues, limited to the region surrounding the anteriorized and extruded part of the KPro. It is not possible to fully understand the mechanisms that trigger the device extrusion. One possible explanation could be a dislocation of the prosthesis in the corneal pocket due to the untied fixation stitch. Another explanation could be a foreign body reaction induced by KPro.

  16. A Case of Primary Hyperparathyroidism due to Intrathyroidal Parathyroid Cyst

    2014-01-01

    Full Text Available Parathyroid cysts constitute 0.08–3.41% of all parathyroid masses. Intrathyroidal parathyroid cysts, however, are rare conditions with only a few cases being reported. Most of the parathyroid cysts are found to be nonfunctional and functional cysts are generally thought to be due to cystic degeneration of parathyroid adenomas. A cystic, smooth contoured lesion of 24 × 19 × 16 mm was observed in left thyroid lobe of a 76-year-old woman during ultrasonography which was performed as routine workup for primary hyperparathyroidism. It was defined as a cystic thyroid nodule at first. Tc99m sestamibi scintigraphy was performed to see any parathyroid lesions, but no radioactive uptake was observed. Intact parathormone (iPTH level was found to be >600 pg/mL in cyst aspiration fluid. Left lobectomy was performed, with a diagnosis of primary hyperparathyroidism due to functional parathyroid cyst. Serum iPTH level was decreased >50% postoperatively and histopathological evaluation was consistent with an encapsulated parathyroid adenoma with a cystic center. Parathyroid cysts are among rare causes of primary hyperparathyroidism. Diagnosis is made by markedly increased iPTH level in cyst fluid and observation of parathyroid epithelium lining the cyst wall.

    Full Text Available In this contribution, we use fading measurements at 2.45, 5.25, 29, and 60 GHz, and wind speed data, to study the dynamic effects of vegetation on propagating radiowaves. A new simulation model for generating signal fading due to a swaying tree has been developed by utilizing a multiple mass-spring system to represent a tree and a turbulent wind model. The model is validated in terms of the cumulative distribution function (CDF, autocorrelation function (ACF, level crossing rate (LCR, and average fade duration (AFD using measurements. The agreements found between the measured and simulated first- and second-order statistics of the received signals through vegetation are satisfactory. In addition, Ricean K-factors for different wind speeds are estimated from measurements. Generally, the new model has similar dynamical and statistical characteristics as those observed in measurements and can thus be used for synthesizing signal fading due to a swaying tree. The synthesized fading can be used for simulating different capacity enhancing techniques such as adaptive coding and modulation and other fade mitigation techniques.

  18. [Risk assessment of work disability due to mental disorders].

    Dohrenbusch, R; Balg, B

    2011-03-01

    For more than 20 years, the rate of work disability pensions due to mental disorders has been rising. This development is in contrast to an overall decrease in the use of disability pension for other diseases. According to an exploratory study by the German state chamber of psychotherapy, most German insurance companies have hindered or excluded insurance protection for customers who have undergone psychotherapy. This practice will be analysed critically because it does not seem to be based on empirical evidence or on established risk algorithms. Results of empirical studies suggest that the use of psychotherapy is not a suitable criterion for the prediction of vocational disabilities due to mental disorders. In contrast, socio-demographic factors such as age or education level, personality factors like neuroticism or attribution style, coping characteristics like exhaustion and cynism, features of the working place like stress or payment conditions, and the type of mental disorder provide better information to calculate the risk of later long-term disability and disability pension caused by mental illness. The impact of these factors has mainly been proven by epidemiological studies from different European countries. Assessment of risk for the use of disability pensions should be based on evidence from epidemiological studies.

    Rabiy Hashemi M

    1997-08-01

    Full Text Available Primary hyperaldosteronism is one of the few causes of hypertension that can be cured by surgery. Primary hyperaldosteronism is caused by adrenocortical adenoma or hyperplasia. It is important to differentiate between adrenal adenoma and hyperplasia because the preferred treatments are different. In all patients with new-onest or worsening hypertension the primary hyperaldosteronism should be considered as an etiology. Patients with primary hyperaldosteronism classically have hypertension with spontaneous hypokalemia. The serum sodium concentration is usually normal in patients with primary aldosteronism who are not taking diuretics. Weakness, fatigue, paresthesia, tetany and even paralysis may develop. Renin and angiotensin II are suppressed in both forms of primary hyperaldosteronism due to feedback. Polyuria may develop secondary to vasopressin resistance from chronic hyperkaliuria. Hypertension or eclampsia during pregnancy is common in women with primary hyperaldosteronism. Case report: A 42-years-old woman presented with headache, severe hypertension, general weakness, easy fatigability, vertigo, palpitation, visual disorders and nocturia. She had a past history of eclampsia 10 years ago. In laboratory investigation there was hypokalemia, elevated serum aldosterone, low renin activity and hyperkaliuria. In abdominal CT-scan there was a hypodense mass measuring 2 cm in diameter in her left adrenal gland. The patient had primary hyperaldosteronism due to aldosteronoma.

    Drivers' ability to react to unpredictable events deteriorates when exposed to highly predictable and uneventful driving tasks. Highway design reduces the driving task mainly to a lane-keeping manoeuvre. Such a task is monotonous, providing little stimulation and this contributes to crashes due to inattention. Research has shown that driver's hypovigilance can be assessed with EEG measurements and that driving performance is impaired during prolonged monotonous driving tasks. This paper aims to show that two dimensions of monotony - namely road design and road side variability - decrease vigilance and impair driving performance. This is the first study correlating hypovigilance and driver performance in varied monotonous conditions, particularly on a short time scale (a few seconds). We induced vigilance decrement as assessed with an EEG during a monotonous driving simulator experiment. Road monotony was varied through both road design and road side variability. The driver's decrease in vigilance occurred due to both road design and road scenery monotony and almost independently of the driver's sensation seeking level. Such impairment was also correlated to observable measurements from the driver, the car and the environment. During periods of hypovigilance, the driving performance impairment affected lane positioning, time to lane crossing, blink frequency, heart rate variability and non-specific electrodermal response rates. This work lays the foundation for the development of an in-vehicle device preventing hypovigilance crashes on monotonous roads.
