Objectives:To report if the association of epilepsy in pediatric patients (below the age of 15 years) with Insulin-dependent Diabetes (IDDM) at King Fahad Medical City (KFMC) is higher than the prevalence of epilepsy in the same age group (who have no IDDM) in our community. Consequently, we would determine if there is a relationship between the presence of epilepsy in diabetic children and the presence of positive antiGAD65 antibodies.Methods:This cohort study included 305 pediatric patients below the age of 15 years with Insulin-dependent Diabetes Mellitus (IDDM). They were randomly recruited at the Pediatric Endocrinology Clinic in KFMC. The patients’ caregivers were given a questionnaire between December 2015 till March 2019 to determine the seizure disorder history. There was also a retrospective review of 214 patients’ files for anti-GAD 65 positivity.Results:Our study found a significant relation between the presence of epilepsy in children with IDDM. Therefore, we could confirm the relationship between the existence of epilepsy in children with IDDM and having positive GAD65 antibodies.Conclusion:Our study supports the presence of consistent relation between having IDDM and having epilepsy in children and between the latter and the presence of positive GAD65 antibodies.Insulin dependent diabetes Mellitus (IDDM) is a common condition in children and adolescents worldwide and so is epilepsy.1,2 Recently, there were increasing reports suggesting a potential association between having IDDM and the occurrence of epilepsy.3 Their association might represent simply a chance to relate their underlying mechanisms. However, the cause-effect relationship is not fully well defined. Literature from other countries have shown the increased prevalence of seizure disorders in this group of patients.4,5 There are scarce studies in the literature investigating IDDM characteristics contributing to having epilepsy, including positive GAD 65 antibodies. In this study that ran in King Fahad Medical City, Riyadh, Kingdom of Saudi Arabia (KSA) we are aiming to determine if the prevalence of epilepsy among 1DDM children under the age of 15 years (in our center) is higher than controls (same age without IDDM), and to check the positivity of anti-GAD 65 amongst those patients in order to find if there is a relationship between epilepsy in children with diabetes and the presence of positive GAD65 Antibodies. 相似文献
Introduction: Ocular dysfunctions and toxicities induced by antiepileptic drugs (AEDs) are rarely reviewed and not frequently received attention by treating physicians compared to other adverse effects (e.g. endocrinologic, cognitive and metabolic). However, some are frequent and progressive even in therapeutic concentrations or result in permanent blindness. Although some adverse effects are non-specific, others are related to the specific pharmacodynamics of the drug.
Areas covered: This review was written after detailed search in PubMed, EMBASE, ISI web, SciELO, Scopus, and Cochrane Central Register databases (from 1970 to 2019). It summarized the reported ophthalmologic adverse effects of the currently available AEDs; their risks and possible pathogenic mechanisms. They include ocular motility dysfunctions, retinopathy, maculopathy, glaucoma, myopia, optic neuropathy, and impaired retinal vascular autoregulation. In general, ophthalmo-neuro- or retino-toxic adverse effects of AEDs are classified as type A (dose-dependent), type B (host-dependent or idiosyncratic) or type C which is due to the cumulative effect from long-term use.
Expert opinion: Ocular adverse effects of AEDs are rarely reviewed although some are frequent or may result in permanent blindness. Increasing knowledge of their incidence and improving understanding of their risks and pathogenic mechanisms are crucial for monitoring, prevention, and management of patients’ at risk. 相似文献
Clear cell renal cell carcinoma (ccRCC) is known to occur across the adult lifetime traversing the spectrum of age-related organismal changes. Little is known as to how the aging process may affect the course of renal cell carcinoma (RCC) and the repertoire of genes involved.
Methods
Using The Cancer Genome Atlas (n?=?436) and Cancer Genomics of the Kidney (n?=?89) datasets, we applied regression analysis to examine associations between patient age and gene expression profiles in ccRCC tumors and normal kidney tissues. Pathway enrichment analysis was performed to identify cellular process that is affected by aging in ccRCC. Moreover, connectivity mapping analysis was used to predict age-dependent response to drug treatments.
Results
Our analysis revealed different age-dependent gene expression spectra in ccRCC and normal kidney tissues. These findings were significant and independently reproducible in both datasets examined. Age up-regulated genes, showing higher expression in older patients, were significantly enriched (false discovery rate <0.05) in normal tissues for pathways associated with immune response and extracellular matrix organization, whereas age up-regulated genes in tumors were enriched for metabolism and oxidation pathways. Strikingly, age down-regulated genes in normal cells were also enriched for metabolism and oxidation, while those in tumors were enriched for extracellular matrix organization. Further in silico analysis of potential drug targets predicted preferential efficacy of Phosphoinositide 3-kinase inhibitor or immunotherapy in association with age.
Conclusion
We report on previously unrecognized associations between age and molecular underpinnings of RCC, including age-associated expression of genes implicated in RCC development or treatment. 相似文献
Chest radiographs of 43 consecutive diabetic patients were evaluated with a view to determine their role as a routine investigation of patients with diabetes mellitus. 22 (51.2%) patients had normal chest radiographs. The remaining 21 patients had 61 abnormalities found in their chest radiographs. 26 (42.6%) of these were significant abnormalities while 35 (57.4%) were non-significant. Of the former, 42.3% were due to cardiomegaly while in the latter group, aortic unfolding was the main finding. Radiological abnormalities were more commonly observed in patients aged 40 years and over, than in those below, with a ratio of 3:1. Chest radiographs corroborated clinical diagnosis in 19 of the 21 cases in whom abnormalities were observed. This study shows that routine chest radiograph in diabetic patients is useful in those with clinical symptoms and in older diabetics above the age of 40 years. 相似文献
Encephalopathy is the most common complication after total portal by-pass operation. 5-15% of patients have severe and intractable encephalopathy. Many medical and surgical procedures were proposed to prevent and treat this complication but none of these were effective. Two cases of patients with severe encephalopathy after side to side portal by-pass are presented. They were treated with the procedure proposed by Bismuth; it consists of a gradual suppression of the anastomosis associated with esophagogastric devascularization. In the first case we obtained the regression of encephalopathy while the second patient died portal thrombosis (probably due to this procedure) two months after surgery. Validity and efficacy of this procedure must be evaluated with a higher number of patients. This surgical technique should lead to choose the type of portal by-pass: side to side portal by-pass operation allows according to Bismuth's procedure to reestablish an hepatopetal flow. 相似文献
Treatment of metronidazole-resistant Trichomonas vaginalis infection is complicated by the lack of an effective alternative therapeutic regimen. Data on the susceptibility of the organism to metronidazole and other nitroimidazoles are important in managing intractable cases. A case of trichomonal vaginitis with true resistance to metronidazole that responded to treatment with tinidazole is reported. 相似文献
Fine needle aspiration cytology is a safe diagnostic technique for breast cancer and can identify certain benign lesions, which can be excised without affecting surrounding tissue. The combination of experienced operator and cytologist can yield high sensitivity and specificity, together with important prognostic information. 相似文献
The routine chest radiographs of 178 psychiatric patients were reviewed. 67 patients had abnormalities found on their chest radiographs. 22 (32.8 pc) of these were significant abnormalities while 45 (67.2 pc) were non-significant. There was no significant abnormality detected on the chest radiographs of any patient in whom abnormality had not been suspected clinically. No significant abnormality was found in patients below the age of 40 years. This study suggests that chest radiography should be performed only on psychiatric patients who are above the age of 40 years and especially those who have clinical evidence of chest disease. 相似文献
Summary: Components of the type 2 immune response may mediate host protection against both helminthic parasites and harmful allergic responses. A central player in this response is the T‐helper 2 (Th2) effector cell, which produces interleukin (IL)‐4, IL‐5, IL‐13, and other Th2 cytokines during the primary and memory response. Specific aspects of the parasite that trigger Th2‐cell differentiation are not yet defined. Furthermore, the cell types and cell surface and secreted molecules that provide the immune milieu required for the development of Th2 effector cells and also Th2 memory cells are not well understood. They will probably vary with the particular helminth or other antigen inducing the Th2 response. We have used third stage larvae of intestinal nematode parasites as adjuvants to promote naïve nonparasite antigen‐specific T cells to differentiate into Th2 cells. This model system avoids possible parasite antigen‐specific T‐cell clones or cross‐reactive memory T cells that may preferentially differentiate into Th2 effector cells during the course of infection and confound the stereotypical components of parasite‐induced Th2 cell differentiation. We have found that these parasites have a potent adjuvant effect and have used our model system to begin to investigate the events that lead to the development of polarized Th2 cells in vivo. 相似文献
