A case of an abdominal cerebrospinal fluid (CSF) pseudocyst in a patient with a ventriculoperitoneal shunt is reported to illustrate this known but rare complication. In the setting of a VP shunt, the frequency of abdominal CSF pseudocyst formation is approximately 3.2%, often being precipitated by a recent inflammatory or infective process or recent surgery. Larger pseudocysts tend to be sterile, whereas smaller pseudocysts are more often infected. Ultrasound and CT each have characteristic findings. 相似文献

Patients with chronic diseases are severely affected by acute coronavirus syndrome. In this regard, patients with beta thalassemia intermedia and diabetes mellitus (DM) are also at high risk for coronavirus‐induced respiratory failure. The present study aimed to report a case with COVID‐19 with a history of chronic diseases, beta thalassemia intermedia, and DM. A 25‐year‐old man visited with complaints of severe shortness of breath, fever, cough without sputum, and tachypnea and admitted to the Intensive Care Unit. The patient had a history of DM, beta thalassemia intermedia, and pervious history of the splenectomy. In peripheral complete blood count (CBC diff), the number of white blood cell count was 41,100 of which 38.6% were lymphocytes. We measured the normal platelet count, hemoglobin level (9.4), and red blood cell count (3.56). ESR was 97, CRP = pos+++ and PCR was positive. The high‐resolution lung CT indicated ground glass opacities in peripheral areas. The patient underwent 13 days of oxygen therapy with reservoir bag‐mask, non‐invasive ventilation, nasal oxygen, and pharmacological treatment with IFN‐β1a and meropenem, and finally discharged with an improvement of the clinical condition. Timely initiation of treatment is very important and significant for patients with beta thalassemia intermedia with COVID‐19, especially despite the underlying disease of DM. According to the present report, the use of IFN‐β1a was effective as a treatment option for COVID‐19. 相似文献

A case of primary cerebral neuroblastoma in adolescence 总被引:1,自引:0,他引:1
Primary cerebral neuroblastoma is one of a group of highly malignant undifferentiated primitive neuroectodermal tumours arising from germinal matrix cells of the embryonic neural tube. They occur primarily in young children and are extremely rare in adults. They may be multicentric and have often spread throughout the central nervous system at the time of diagnosis. A case of a 16-year-old man is described, and the recent literature is reviewed. 相似文献

Background
Electrocardiogram (ECG) is the first available modality used in patients with chest pain and dyspnea in emergency rooms.We aimed to study differences between acute coronary syndrome (ACS) and acute pulmonary embolism (APE) in patients presented primarily with abnormal negative T waves on their admission Electrocardiogram.Methods
This research was a retrospective study in which 297 patients (97 patients with APE and 200 with ACS) were included. The patients were admitted to the emergency ward of a tertiary heart center between 2015 and 2017. In addition to the evaluation of distribution of negative T waves, the depth of the inverted precordial T waves was measured.Results
The mean age of patients was 62.0?±?11.4 in ACS group and 60.7?±?17.6 in APE group (P value?=?0.563). Total negative T in V3 and V4 in ACS and APE groups was 9.1?mm and 4.2?mm respectively (P value <0.001).Total magnitude of negative T in anterior leads divided by total magnitude of negative T in inferior leads for ACS and APE groups were 15.1?±?12.0 and 5.4?±?3.6 respectively (P value?=?0.001).ROC curves showed that total magnitude of negative T in V4 divided by negative T in V1 can be valuable. A cutoff point of 1.75 with sensitivity of 73.5% and specificity of 84.9% (95% CI 0.79–0.91 P?<?0.001) could differentiate APE patients from ACS patients.Conclusion
This study suggests that total magnitude of negative T in left precordial leads divided by right precordial leads can be valuable in differentiating APE from ACS. 相似文献5.

Background:
Cervical cancer is the most second common cancer among Iranian women. This study was carried out to compare the results of Pap smear method and Direct Visual Inspection (DVI) with 5% acetic acid in cervical cancer screening in Tabriz, Iran.Material and Methods:
This cross-sectional study was carried out in Alzahra Therapeutic-Educational Centre, Tabriz, Iran in 2013 on 1000 women. First, Pap smear was done for all women, and then the cervix exposed with 5% acetic acid by cotton swab for 30 seconds and observed under adequate light. At the end, women with abnormal results in Pap smear or DVI method were referred to colposcopy and biopsy. Test''s sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), LR+, LR- and confidence interval (CI) were determined (P < 0.05).Results:
Nine-hundred and seventy-four (94.7%) cases were normal and had no abnormal findings and 26 (2.6%) participants had positive results in Pap smear or DVI test. Twelve women had abnormal Pap smear (nine women with atypical squamous cells of undetermined significance, ASCUS, three women with dysplasia, atypical endocervical, and low-grade squamous intraepithelial lesion, LSIL results) and 14 women had positive DVI (four women with human papillomavirus, HPV or koilocyte,) and one women with abnormality in both method had carcinoma in biopsy that referred to oncologist. In this study the sensitivity, specificity, PPV and NPV for DVI were 71.4%, 50%, 35.7%, and 81.8% respectively in comparison with 14.3%, 50%, 10%, and 60% for Pap smear.Conclusion:
As the DVI method has higher sensitivity and positive predictive value than Pap smear, it could be used as a useful method beside the Pap smear. 相似文献6.

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic inflammatory disorder characterized by progressive heterotopic ossification presenting as recurrent soft tissue masses and swelling which may cause disabling, restricted joint mobility. Congenital malformations of the hallux are characteristic features of classic FOP, predating the appearance of disabling features. As no definite treatment is available, the early diagnosis and prevention of exacerbating factors may lead to significant benefits in terms of the life quality of patients. A retrospective study of 12 consecutive FOP patients referred to and admitted in the rheumatology unit at an urban tertiary care academic center between 1991 and 2011. Data, such as age, gender, and past medical history, were collected from the medical history, physical examination, and skeletal survey in order to characterize the clinical presentations. All 12 children (six boys and six girls; ages 2.0-13.5 years) had congenital malformations of the great toes (microdactyly and hallux valgus deformity), in addition to heterotopic ossification presenting as multiple soft tissue tumor-like swellings. Spinal involvement, most notably in the cervical region, suggestive of an early FOP, was present in 83.3 %. Eleven patients (91.6 %) had a prior history of direct physical trauma, while 7 of 11 (63.6 %) had undergone invasive diagnostic procedures, both correlating with the exacerbations of their condition. Clinical awareness of fibrodysplasia ossificans progressiva and its early diagnostic features, particularly congenital malformations of the hallux, during a thorough neonatal examination may lead to an early diagnosis preventing the development of disabling, practically irreversible lesions of heterotopic ossification. Genetic and molecular studies can play a considerable role in the diagnosis of FOP in suspected cases. Early institution of prophylactic and precautionary measures, such as categorical avoidance of trauma and invasive procedures, can significantly reduce the debilitating acute exacerbations of the condition. 相似文献

A series of sila‐organosulphur compounds containing 1,2,3‐triazole cores were screened for their cytotoxic activity on human breast cancer cell line MCF‐7. Most of the tested compounds exhibited moderate‐to‐good activity against the cancer cells. Especially, the compound 4‐((2‐(trimethylsilyl)ethynylthio)methyl)‐1‐benzyl‐1H‐1,2,3‐triazole ( 3a) from series of sila‐substituted thioalkyne 1,2,3‐triazoles (STATs) and the compounds 3‐(1‐benzyl‐1H‐1,2,3‐triazol‐4‐yl)‐1‐mercapto‐1,1‐bis(trimethylsilyl)propane‐2‐thione ( 4a) and 1‐mercapto‐1,1‐bis(trimethylsilyl)‐3‐(1‐phenethyl‐1H‐1,2,3‐triazol‐4‐yl)propane‐2‐thione ( 4e) from series of sila‐substituted mercapto‐thione 1,2,3‐triazoles (SMTTs) exhibited promising cytotoxicity against MCF‐7 with IC50 values of 35.17, 32.63 and 30.3 μg/mL, respectively. In addition, the possible mechanisms for inhibition of cell growth and induction of apoptotic cell death were explored by DAPI staining, cell cycle analysis and qRT‐PCR. The synthetic compounds were evaluated for their in vitro antibacterial activities, and as a result, the most prominent effects were observed for 3e and 4e . Especially, 3e was found to be quite active against all the tested strains with the MIC values ranging from 15 to 62 μg/mL, except P. aeruginosa. The results of the time‐kill assay suggested that the compound of 3e completely inhibited the growth of both gram‐negative bacteria, A. baumannii, and gram‐positive bacteria, S. aureus. In addition, SEM analysis confirmed morphostructural damage of the bacteria. Our findings could be applicable for developing dual‐targeting anticancer/antibacterial therapeutics. 相似文献

Introduction
Long-chain polyunsaturated fatty acids, the most abundant fatty acids in the brain, are essential for the growth and development of the brain and the retina.Objective
To evaluate the effect of fish oil supplementation on the development (primary outcome) and growth of 4- and 6-month-old infants.Methods
In this triple-blind randomized controlled trial, 150 pregnant women aged 18–35 years, who were referred to healthcare centres of Tabriz-Iran, were randomly allocated into two groups. One group of women consumed fish oil supplementation (containing 120 mg docosahexaenoic acid and 180 mg eicosapentaenoic acid) daily, while the other consumed a placebo from the 20th week of pregnancy till 30 days after childbirth in a parallel design by a computer-generated block randomization scheme. The neurodevelopment of infants was the primary outcome; it was assessed using the ages and stages questionnaire (ASQ) at 4- and a-6 months of age. The growth of these infants was measured using weight, length and head circumference. The participants, the caregivers, and those assessing the outcomes were blind to the group assignment.Results
Only one woman in the placebo group discontinued the intervention because of persistent severe nausea. All 75 neonates aged 4- and a-6 months in the fish oil supplementation group, along with 73 and 71 neonates aged 4 and 6 months, respectively in the placebo group, were followed and analysed. Although the mean scores of neurodevelopment at the end of 4 and 6 months were higher in the supplemented group than in the placebo group in each ASQ domain, a statistically significant difference was observed only in the communication domain at the 4th month (adjusted mean difference 2.63; 95% confidence interval 0.36–4.89). There was no significant difference in weight, length, or head circumference between the two groups of infants aged 4 and 6 months (P ≥ 0.05).Conclusion
Based on the results, perinatal fish oil supplementation is beneficial for the communication domain of neurodevelopment of 4-month-old infants. The study results relating to the supplementation effect on other domains are inconclusive. There ought to be further studies with up-to-date lipidomic analysis to find biochemical correlate compared to an intervention and developmental finding.9.

PurposeThere is conflicting evidence regarding whether a loss of radial peripapillary capillaries (RPCs) precedes neuronal loss in glaucoma. We examined the time course of in vivo changes in RPCs, optic nerve head (ONH) structure, and retinal nerve fiber layer thickness (RNFLT) in experimental glaucoma (EG).MethodsSpectral domain optical coherence tomography images were acquired before and approximately every two weeks after inducing unilateral EG in nine rhesus monkeys to quantify mean anterior lamina cribrosa surface depth (ALCSD), minimum rim width (MRW), and RNFLT. Perfused RPC density was measured from adaptive optics scanning laser ophthalmoscope images acquired on the temporal half of the ONH. The time of first significant change was quantified as when values fell and remained outside of the 95% confidence interval established from control eyes.ResultsMean ALCSD and/or MRW were the first parameters to change in eight EG eyes. RPC density changed first in the ninth. At their first points of change, mean ALCSD posteriorly deformed by 100.2 ± 101.2 µm, MRW thinned by 82.3 ± 65.9 µm, RNFLT decreased by 25 ± 14 µm, and RPC density decreased by 4.5 ± 2.1%. RPC density decreased before RNFL thinning in 5 EG eyes. RNFLT decreased before RPC density decreased in two EG eyes, whereas two EG eyes had simultaneous changes.ConclusionsIn most EG eyes, RPC density decreased before (or simultaneous with) a change in RNFLT, suggesting that vascular factors may play a role in axonal loss in some eyes in early glaucoma. 相似文献

The identification of multiple signals at individual loci could explain additional phenotypic variance ('missing heritability') of common traits, and help identify causal genes. We examined gene expression levels as a model trait because of the large number of strong genetic effects acting in cis. Using expression profiles from 613 individuals, we performed genome-wide single nucleotide polymorphism (SNP) analyses to identify cis-expression quantitative trait loci (eQTLs), and conditional analysis to identify second signals. We examined patterns of association when accounting for multiple SNPs at a locus and when including additional SNPs from the 1000 Genomes Project. We identified 1298 cis-eQTLs at an approximate false discovery rate 0.01, of which 118 (9%) showed evidence of a second independent signal. For this subset of 118 traits, accounting for two signals resulted in an average 31% increase in phenotypic variance explained (Wilcoxon P< 0.0001). The association of SNPs with cis gene expression could increase, stay similar or decrease in significance when accounting for linkage disequilibrium with second signals at the same locus. Pairs of SNPs increasing in significance tended to have gene expression increasing alleles on opposite haplotypes, whereas pairs of SNPs decreasing in significance tended to have gene expression increasing alleles on the same haplotypes. Adding data from the 1000 Genomes Project showed that apparently independent signals could be potentially explained by a single association signal. Our results show that accounting for multiple variants at a locus will increase the variance explained in a substantial fraction of loci, but that allelic heterogeneity will be difficult to define without resequencing loci and functional work. 相似文献
