Risk of Atopic Diseases in Patients with Hidradenitis Suppurativa: A Systematic Review and Meta-Analysis of Observational Studies.

BACKGROUND: Hidradenitis suppurativa (HS) and allergic diseases were considered to have different immune pathways involved. However, available evidences seemed to be inconsistent and the association was not well-developed yet. OBJECTIVE: The aim of this study was to perform a systematic review and meta-analysis to evaluate the association between HS and atopic diseases, including asthma, atopic dermatitis, allergic rhinitis, and conjunctivitis. METHODS: Search in databases including PubMed, Embase, and Web of Science was performed. Synonyms were determined based on MeSH terms and Emtree. Observational studies with proper comparative arm were selected. For quality evaluation of extracted studies, the Newcastle-Ottawa Scale was utilized. Odds ratio of atopic dermatitis, asthma, allergic rhinitis, and conjunctivitis were evaluated in HS patients (comparing with non-HS people). I2 value was applied to evaluate the heterogeneity within studies. RESULTS: After appraising 1,654 studies, in total, 12 studies were selected for data extraction. In adjusted models, people with HS is significantly associated with higher risk of having asthma, with a pooled odds ratio of 1.50 (95% CI, 1.24-1.81). Risk of presenting atopic dermatitis in HS patients was also increased, with an odd ratio of 4.10 (95% CI, 2.16-8.18). The association remained its significance in sensitivity models. Evidences were insufficient to support the association between HS and allergic rhinitis and conjunctivitis. CONCLUSION: Current evidence supported that atopic dermatitis and asthma were associated with HS. Physicians should be aware of the reported association while caring people with HS and related screening of allergies comorbidities should be recommended.

Adverse Events of Everolimus in Patients with Tuberous Sclerosis Complex Treated for Renal Angiomyolipoma/Subependymal Giant Cell Astrocytoma.

Background: Although regarded as a potentially efficient approach to address tuberous sclerosis complex (TSC)-associated complications, the adverse event profile of everolimus has not yet been fully elucidated. The present study aimed to clarify the adverse event spectrum in patients with TSC who are using everolimus for common indications, in comparison to those who do not use everolimus. Materials and Methods: We recruited patients with TSC who were followed up annually at TSC integrated clinics or referred for medical assistance. Medical reviews and laboratory investigations were performed at baseline and annually by clinical physicians. The adverse events were assessed as per the National Cancer Institute Common Terminology Criteria for Adverse Events. Results: Common adverse events in everolimus users included hypercholesterolemia (55%), gingivostomatitis (50%), proteinuria (50%), and hyperglycemia (40%). Compared with everolimus nonusers, the occurrence of gingivostomatitis and proteinuria was significantly higher in everolimus users (gingivostomatitis, p=0.02; proteinuria, p=0.02). Among the everolimus users, 12 patients had level I CTCAE, and five had level II CTCAE. None of the everolimus users presented with CTCAE level III or higher. Conclusion: Patients with TSC who are everolimus users had a higher tendency to develop gingivostomatitis and proteinuria compared to nonusers. However, no differences were observed in the occurrence of other adverse events between everolimus users and nonusers.

The use of progressive addition lenses to improve the daily visual function of children receiving topical atropine treatment.

PURPOSE: To evaluate the changes in visual function when progressive addition lenses (PAL) are added in children using topical atropine as a myopia control therapy. Daily visual complaints and the determination of their near correction were studied. METHODS: Forty children aged 7-12 years were recruited. Distance and near visual acuity, accommodative lag, heterophoria, near point of convergence and stereopsis were examined, and a questionnaire of daily visual complaints was administered. RESULTS: Significant differences in visual functions were found after the near correction was prescribed. Significant improvements in distance and near visual acuity, lag of accommodation and binocular visual function were observed, and fewer visual complaints were reported at the Harmon distance. CONCLUSION: The use of PAL is helpful for children undergoing topical atropine treatment for myopia control, particularly those receiving medium to high doses. This combination therapy could also be applied to younger children who have a low tolerance to contact lenses, with less risk of ocular adverse effects.

Epilepsy and Attention Deficit Hyperactivity Disorder: Connection, Chance, and Challenges.

Comorbidities are common in children with epilepsy, with nearly half of the patients having at least one comorbidity. Attention deficit hyperactivity disorder (ADHD) is a psychiatric disorder characterized by hyperactivity and inattentiveness level disproportional to the child's developmental stage. The burden of ADHD in children with epilepsy is high and can adversely affect the patients' clinical outcomes, psychosocial aspects, and quality of life. Several hypotheses were proposed to explain the high burden of ADHD in childhood epilepsy; the well-established bidirectional connection and shared genetic/non-genetic factors between epilepsy and comorbid ADHD largely rule out the possibility of a chance in this association. Stimulants are effective in children with comorbid ADHD, and the current body of evidence supports their safety within the approved dose. Nonetheless, safety data should be further studied in randomized, double-blinded, placebo-controlled trials. Comorbid ADHD is still under-recognized in clinical practice. Early identification and management of comorbid ADHD are crucial to optimize the prognosis and reduce the risk of adverse long-term neurodevelopmental outcomes. The identification of the shared genetic background of epilepsy and ADHD can open the gate for tailoring treatment options for these patients through precision medicine.

The Efficacy of Everolimus for Facial Angiofibromas in Tuberous Sclerosis Complex Patients Treated for Renal Angiomyolipoma/Subependymal Giant Cell Astrocytoma.

BACKGROUND: Facial angiofibromas may be present since early childhood in individuals with tuberous sclerosis complex (TSC), causing substantial cosmetic disfigurement. Current therapies are partially effective, but they are uncomfortable, produce scarring, and are especially expensive. OBJECTIVE: The aim of the present study was to evaluate the efficacy of oral everolimus for TSC-associated angiofibromas. METHODS: This retrospective study included TSC patients being treated with oral everolimus for subependymal giant cell astrocytomas (SEGAs) and angiomyolipomas (AMLs). We recorded the changes in facial angiofibromas. Changes in the Angiofibroma Grading Scale (AGS) indicators were recorded according to erythema, average lesion size, lesion density, and percent involvement on the forehead, nose, cheeks, and chin. The scores were recorded before and after the administration of oral everolimus. RESULTS: Twenty-one patients being treated with oral everolimus were enrolled in this study. The mean age was 20.5 years (range 11-44 years, 4 males, and 17 females). The mean dose of oral everolimus was 3.6 mg/day. Clinically meaningful and statistically significant improvement was observed in erythema (p = 0.001), average lesion size (p < 0.001), lesion density (p < 0.001), and percent involvement (p < 0.001). Changes in the AGS findings were statistically significant on the forehead (p = 0.001), nose (p < 0.001) cheeks (p < 0.001), and chin (p = 0.004). CONCLUSION: Everolimus shows evident improvement and is approved for TSC-associated SEGAs and AMLs. The current study demonstrated the efficacy of oral everolimus in reducing facial angiofibromas, showing the parallel benefits of the treatment protocol for TSC.

Disrupted white matter connectivity and organization of brain structural connectomes in tuberous sclerosis complex patients with neuropsychiatric disorders using diffusion tensor imaging.

OBJECTIVE: Tuberous sclerosis complex (TSC) is a genetic neurocutaneous syndrome with variable and unpredictable neurological comorbidity that includes epilepsy, intellectual disability (ID), autism spectrum disorder, and neurobehavioral abnormalities. The degree of white matter involvement is believed to be associated with the severity of neurological impairment. The goal of the present study was to evaluate diffusion characteristics of tubers, white matter lesions, and brain structural network alterations in TSC patients using diffusion tensor imaging (DTI), graph theoretical analysis (GTA), and network-based statistical (NBS) analysis. MATERIALS AND METHODS: Forty-two patients with a definitive diagnosis of TSC were recruited for this study. All patients underwent brain DTI examination using a 3 T magnetic resonance imaging system. Mean diffusivity (MD), axial diffusivity (AD), radial diffusivity (RD) values, and fractional anisotropy (FA) mapping in 52 tubers and white matter lesions were measured and compared with those of contralateral normal regions. GTA was performed on the inter-regional connectivity matrix, and NBS analysis was used to identify the significance of any connected subnetworks evident in the set of altered connections. For neurological severity subgrouping, a neurological severity score was assigned to TSC patients including those with ID, seizure, autism, and other neuropsychiatric disorders (NPDs). RESULTS: Significantly higher MD, AD, and RD, and lower FA values, were found in TSC lesions compared with those measured in contralateral normal regions for tubers (P < 0.05). GTA and NBS analysis provided better local segregation but worse global integration of the structural network (regular-like network) in TSC patients with ID, seizure, and higher Neurological Severity Score. Disrupted subnetworks in TSC patients with severe status included connections from the frontal lobe to the parietal lobe, temporal lobe to the caudate, and temporal lobe to the insula. DISCUSSION: DTI has the potential to provide valuable information about cytoarchitectural changes in TSC lesions beyond morphological MRI findings alone. Using GTA and NBS, current results provide the information of disrupted white matter connectivity and organization in TSC patients with different neuropsychological impairments.

Is Neonatal Hyperbilirubinemia Exposure Associated with a Risk of Autism Spectrum Disorder? A Nationwide Cohort Study.

OBJECTIVE: This study aimed to determine whether neonatal hyperbilirubinemia is associated with a risk of autism spectrum disorder (ASD) using a large population-based cohort. STUDY DESIGN: This retrospective cohort study used data from the children's database (2000-2012) of the National Health Insurance Research Database (1996-2012) in Taiwan. We included neonates who were born between 2000 and 2004 and aged <1 month diagnosed with and without hyperbilirubinemia. The primary outcome was physician-diagnosed ASD. At the end of 2012, multivariate Cox's regression analysis was used to estimate hazard ratios (HRs). RESULTS: A total of 67,017 neonates were included. The neonates with hyperbilirubinemia were associated with 1.28-fold increased risk of ASD (HR = 1.28, 95% confidence interval [CI]: 1.05-1.57) compared with those without hyperbilirubinemia. In subanalysis to determine how phototherapy and exchange transfusion treatment for hyperbilirubinemia were associated with ASD showed no association between treatment and ASD, suggesting the lack of a dose-response effect of hyperbilirubinemia on the risk of ASD. Boys had a nearly six-fold higher risk of ASD than girls (HR = 5.89, 95% CI: 4.41-7.86). Additionally, neonates born with preterm birth and low birth weight were associated with a risk of ASD (HR = 1.46, 95% CI: 1.00-2.13). CONCLUSION: We did not observe a dose-response effect of hyperbilirubinemia on ASD, but neonatal hyperbilirubinemia may be an independent risk factor for ASD if there is a residual confounding by other perinatal complications. Therefore, this study does not support a causal link between neonatal hyperbilirubinemia exposure and the risk of ASD.

Vagus nerve stimulation for patients with refractory epilepsy: Demographic features and neuropsychological outcomes of the VNS Taiwan child neurology society database.

OBJECTIVES: Vagus nerve stimulation (VNS) is an established adjunctive therapy for medically refractory epilepsy, which is commonly associated with cognitive impairment, especially in children in whom seizures may disrupt development that is essential to their intellectual and social maturation. The Taiwan Child Neurology Society intends to expand the use of VNS by reporting the experience in a nationwide population, displaying the demographic features and neuropsychological outcomes of VNS. METHODS: The enrollment included 105 patients of all ages and seizure types who underwent VNS implantation for refractory epilepsy. Basic data included etiology, past history, seizure phenotypes, and epileptiform syndromes. For efficacy analysis, seizure frequencies were recorded at the baseline and at 3, 12, 24, and 36 months after VNS implantation. For psychological assessment, intelligence quotients (IQ) and Parental Stress Index (PSI) scores were evaluated before and after the VNS. RESULTS: During the study period, 95 patients with VNS had followed seizure frequency, IQ and PSI recording. After implantation, there was a decreased frequency at 3 (P < .001), 12 (P < .001), 24 (P = .010), and 36 (P < .01) months. After implantation, the reduction rate (0-50%) of seizure frequency ranged around 26.1-36.1% from 3 to 36 months. For PSI scores, the VNS significantly improved the PSI- total score (P = .001) and PSI-parent domain (P = .001) but not the PSI-children domain (P = .052). No significant improvement in the IQ test performance was observed. CONCLUSIONS: This prospective nationwide database of VNS in Taiwan indicates long-term efficacy of VNS therapy, which has achieved a trend of seizure frequency reduction over a period of up to 36 months. It also shows the trend of decreased parental stress after VNS implantation.

Targeting Telomerase and ATRX/DAXX Inducing Tumor Senescence and Apoptosis in the Malignant Glioma.

Glioblastoma multiforme (GBM) is a type of brain tumor that is notorious for its aggressiveness and invasiveness, and the complete removal of GBM is still not possible, even with advanced diagnostic strategies and extensive therapeutic plans. Its dismal prognosis and short survival time after diagnosis make it a crucial public health issue. Understanding the molecular mechanisms underlying GBM may inspire novel and effective treatments against this type of cancer. At a molecular level, almost all tumor cells exhibit telomerase activity (TA), which is a major means by which they achieve immortalization. Further studies show that promoter mutations are associated with increased TA and stable telomere length. Moreover, some tumors and immortalized cells maintain their telomeres with a telomerase-independent mechanism termed the "alternative lengthening of telomeres" (ALT), which relates to the mutations of the α-thalassemia/mental retardation syndrome X-linked protein (ATRX), the death-domain associated protein (DAXX) and H3.3. By means of the mutations of the telomerase reverse transcriptase (TERT) promoter and ATRX/DAXX, cancers can immortalize and escape cell senescence and apoptosis. In this article, we review the evidence for triggering GBM cell death by targeting telomerase and the ALT pathway, with an extra focus on a plant-derived compound, butylidene phthalide (BP), which may be a promising novel anticancer compound with good potential for clinical applications.

Vagus nerve stimulation for 6- to 12-year-old children with refractory epilepsy: Impact on seizure frequency and parenting stress index.

OBJECTIVES: Refractory epilepsy (RE) is frequently associated with neuropsychological impairment in children and may disrupt their social development. Vagus nerve stimulation (VNS) had been reported to have beneficial effects on behavioral outcomes. The aim of this study was to compare Parenting Stress Index (PSI) scores before and after VNS device implantation in children with RE, especially those who experienced seizure frequency reduction. METHODS: We conducted a one-group pretest-posttest study in school age children with RE. Seizure frequency and PSI were recorded at 12months after VNS device implantation. RESULTS: Treatment with VNS was significantly associated with reduced seizure frequency and parental stress as measured by PSI. Factors contributing to seizure frequency included idiopathic/cryptogenic etiology and neurobehavioral comorbidities. In children with reduced seizure frequency, statistically significant improvements in the child domain of the PSI on the subscales of mood and reinforces parent were found. In the parent domain, the scores for social isolation were reduced. CONCLUSIONS: Treatment with VNS was significantly associated with reduced seizure frequency and improved PSI scores, especially within the child domain on the mood and reinforces parent subscales. These findings suggest that VNS reduced not only seizure frequency but also the psychological burden on children with RE.

Association between allergic disease, sleep-disordered breathing, and childhood nocturnal enuresis: a population-based case-control study.

BACKGROUND: Little is known about the associations between allergic disease, sleep-disordered breathing (SDB), and childhood nocturnal enuresis (NE). We examined whether allergic disease and SDB were associated with childhood NE. METHODS: Data were assessed from the 2007-2012 Taiwan National Health Insurance Research Database. We enrolled 4308 children aged 5-18 years having NE diagnosis and age- and sex-matched 4308 children as the control group. The odds ratios of NE were calculated to determine an association with preexisting allergic disease and SDB. RESULTS: A total of 8616 children were included in the analysis. Prevalence of allergic diseases and SDB was significantly higher for the NE group than the control group (all p < 0.001). After adjusting odds ratios for potential confounding factors, except asthma, children with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and obstructive sleep apnea (OSA) had significantly higher odds of NE compared with children never diagnosed. With stratification for sex, girls with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, OSA, and snoring had significantly higher odds of NE, compared with girls never diagnosed. Only boys with allergic rhinitis and OSA were associated with increased odds of NE. With stratification for age, children aged 5-12 years with allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and OSA had significantly higher odds of NE compared with those never diagnosed. Odds of NE increased with the number of comorbid allergic diseases. CONCLUSIONS: Allergic diseases and SDB are associated with increased odds of childhood NE. The odds of NE increased with the number of comorbid allergic diseases present.

Effects of everolimus on tuberous sclerosis complex-associated renal angiomyolipoma: A preliminary report.

AIM: Tuberous sclerosis complex (TSC) presents with multisystem benign neoplasm induced by dysregulation of the mammalian target of rapamycin pathway. This study aimed to examine the effects of oral everolimus at either 2.5 or 5.0 mg daily on the treatment of TSC-associated renal angiomyolipoma (AML). METHODS: Between July 2012 and August 2015, patients with TSC-associated renal AML were selected for everolimus therapy protocol. An oral everolimus starting dose at 2.5 mg was administered daily, and was gradually increased to 5.0 mg daily. All patients were evaluated using magnetic resonance imaging or computed tomography scanning at baseline, 12, 24, and 36 months after the start of treatment for measuring the changes of renal AML mass volume. RESULTS: Eight patients were finally enrolled for analysis in this study. Everolimus treatment had a statistically significant effect on the renal AML volume reduction during follow-up (P < 0.05). Renal AML mass volume reduction rates were 10.5-45.3% in four patients with everolimus 2.5 mg and 40.7-73.1% in four patients with everolimus 5.0 mg daily; the difference was statistically significant between the two groups (P < 0.05). Longitudinal follow-up for response to everolimus showed volume reduction rates to be around 10.5-73.1% in the initial 6-24 months after everolimus treatment, which remained stable during follow-up up to 36 months. CONCLUSION: The results suggest that an oral everolimus is effective and provides a non-invasive way to treat TSC-associated renal AML, and patients are likely to require maintenance therapy to continue to derive benefit.

The neuropsychological outcome of pediatric patients with refractory epilepsy treated with VNS--A 24-month follow-up in Taiwan.

OBJECTIVES: Multiple studies have reported the benefits of vagus nerve stimulation (VNS) on neuropsychological outcomes. The aim of this study was to investigate how VNS affects cognition and psychosocial adjustment in children with refractory epilepsy (RE), and to determine the efficacy of VNS in a Taiwanese population. METHODS: We conducted a one-group pretest-posttest study on pediatric patients with RE. The study comprised 19 males and 18 females, all aged <18 years. We recorded seizure frequency at 3, 12, and 24 months after VNS device implantation. Intelligence quotients (IQ) were assessed using the Wechsler Intelligence Scale for Children - IV. The Parental Stress Index (PSI) scores were evaluated by a pediatric psychologist. RESULTS: Vagus nerve stimulation device implantation significantly reduced seizure frequency at 3, 12 and 24 months, especially in young children (<12 years). No significant improvement in IQ test performance was observed, though there were significant improvements in the PSI, especially in young children. CONCLUSIONS: Vagus nerve stimulation device implantation does not significantly improve cognition function, but it does significantly reduce seizure frequency and stress in parent-child relationships, especially in young children (<12 years). These findings suggest that VNS should be considered as an alternative therapy for patients proven to have seizures that are medically refractory, especially those younger than 12 years of age.

Association between the growth rate of subependymal giant cell astrocytoma and age in patients with tuberous sclerosis complex.

PURPOSE: The most common neurological complications associated with tuberous sclerosis complex (TSC) include intractable seizures that begin in infancy and subependymal giant cell astrocytoma (SEGA) complicated by hydrocephalus with increasing age. Information on SEGA growth of TSC patients is limited. This study aimed to examine the TSC-SEGA growth rates by periodic neuroimaging. METHODS: This study evaluated the TSC-SEGA growth rates by serial neuroimaging. Fifty-eight patients with TSC underwent systematic evaluation, including a review of medical history and serial brain neuroimaging. RESULTS: While magnetic resonance imaging was more sensitive in detecting cortical tubers than computed tomography (73.1 vs. 0 %, p < 0.001), its efficacy in identifying intracranial lesions was comparable to that of computed tomography (96.2 vs. 100 %, p = 0.658). Significant tumor growth was observed in children (p = 0.012) and adults (p = 0.028) during follow-up periods, respectively (median for children 23.5 months, interquartile range 18-40 months and median for adults 23 months, interquartile range 12-34 months). Further, the SEGA growth rate in children was significantly higher than that in adults (75.6 vs. 16.5 %, p = 0.03). CONCLUSIONS: The results of the study show that SEGA has a significantly higher growth rate in children using serial follow-up brain imaging, suggesting the importance of performing follow-up neuroimaging at yearly intervals in childhood to identify and prevent potential comorbidities.

Targeting New Candidate Genes by Small Molecules Approaching Neurodegenerative Diseases.

Neurodegenerative diseases (NDs) are among the most feared of the disorders that afflict humankind for the lack of specific diagnostic tests and effective treatments. Understanding the molecular, cellular, biochemical changes of NDs may hold therapeutic promise against debilitating central nerve system (CNS) disorders. In the present review, we summarized the clinical presentations and biology backgrounds of NDs, including Parkinson's disease (PD), Huntington's disease (HD), and Alzheimer's disease (AD) and explored the role of molecular mechanisms, including dys-regulation of epigenetic control mechanisms, Ataxia-telangiectasia-mutated protein kinase (ATM), and neuroinflammation in the pathogenesis of NDs. Targeting these mechanisms may hold therapeutic promise against these devastating diseases.

Increased incidence of juvenile-onset systemic lupus erythematosus among children with asthma.

BACKGROUND: Children with systemic lupus erythematosus (SLE) have an especially aggressive disease course and poor outcomes. Previous studies demonstrated a possible association between SLE and allergies, but the relationship between these disorders remains unclear. This population-based cohort study aimed to investigate the incidence and risk of juvenile-onset SLE (JSLE) among children with asthma. METHODS: From 2000 to 2003, 120,939 children with newly diagnosed asthma and 483,756 randomly selected non-asthma controls were enrolled. We used a multivariable Cox proportional hazard regression model to measure and compare the incidence rate and risk of JSLE in the asthma and non-asthma cohorts. RESULTS: The overall incidence of JSLE was 2.52 times greater in the asthma cohort than that in the non-asthma cohort [3.49 vs. 1.53 per 100,000 person-years; 95% confidence interval (CI): 1.59-3.99]. The risk of JSLE was greatest among boys [hazard ratio (HR) 3.02, 95% CI: 1.21-7.52] and children aged 6-10 yr (HR 3.50, 95% CI: 1.75-7.02). The HR of JSLE increased with greater frequency of asthma-related medical visits from 1.22 (95% CI: 0.67-1.41) for those with ≤2 visits/yr to 5.88 (95% CI: 3.43-10.1) for subjects with >2 visits/yr (trend test p < 0.001). However, the risk of JSLE declined over time. CONCLUSION: We found an increased incidence of JSLE among children with asthma. The mechanism of asthma on JSLE development should be elucidated to establish innovative disease intervention programs.

Neurological images and the predictors for neurological sequelae of epidemic herpangina/hand-foot-mouth disease with encephalomyelitis.

Since 1998 in Taiwan, enterovirus (EV) 71 epidemics have caused encephalomyelitis and placed a significant burden on parents and physicians. In this study, we present clinical manifestations, magnetic resonance (MR) imaging findings, and neurological sequelae on epidemic EV-infected patients with encephalomyelitis. Of the 46 patients, 14 patients presented with neurological sequelae; of them, 3 patients suffered from complications of mental regression. Predictors of unfavorable neurological sequelae were myoclonic jerks (> 4 times/night) and pleocytosis (167/µL) of the cerebrospinal fluid (CSF). Results from viral culture and MR imaging indicated that positive identification of EV71 infection was associated significantly with lesions on MR imaging. Our results show that hand-foot-mouth disease carries a higher risk of encephalomyelitis and that frequent myoclonic jerks and pleocytosis of the CSF are risk factors for subsequent neurological sequelae. Positive identification of EV71 might be useful as a predictor of lesions in MR imaging.

Comparison of procalcitonin and different guidelines for first febrile urinary tract infection in children by imaging.

BACKGROUND: We examined the ability of a procalcitonin (PCT) protocol to detect vesicoureteral reflux (VUR) and renal scarring (RS), evaluated procedural costs and radiation burden, and compared four representative guidelines for children with their first febrile urinary tract infection (UTI). METHODS: Children aged ≤2 years with their first febrile UTI who underwent renal ultrasonography (US), acute and late technetium-99m ((99m)Tc)-dimercaptosuccinic acid scan, and voiding cystourethrography were prospectively studied. The representative guidelines applied in a retrospective simulation included the American Academy of Pediatrics (AAP), National Institute of Clinical Excellence, top-down approach (TDA), and Italian Society of Pediatric Nephrology (ISPN). These were compared in terms of ability to detect abnormalities, procedural costs and radiation. RESULTS: Of 278 children analyzed, 172 (61.9%) had acute pyelonephritis. There was VUR in 101 (36.3%) children, including 73 (26.3%) with grades III-V VUR. RS was identified in 75 (27.0%) children. To detect VUR, TDA and PCT had the highest sensitivity for grades I-V VUR (80.2%) and III-V VUR (94.5%), respectively, whereas AAP had the highest specificity for I-V VUR (77.4%) and III-V VUR (78.0%), respectively. TDA and PCT had the highest sensitivity (100%) for detecting RS. The highest cost and radiation dose was associated with TDA, whereas AAP had the least expenditure and radiation exposure. By multivariate analysis, PCT and VUR, especially grades III-V, were independent predictors of RS. CONCLUSIONS: There is no perfect guideline for first febrile UTI children. The PCT protocol has good ability for detecting high-grade VUR and RS. If based on available imaging modalities and reducing cost and radiation burden, clinical suggestions in the AAP guidelines represent a considerable protocol.

Increased risk of idiopathic nephrotic syndrome in children with atopic dermatitis.

BACKGROUND: Clinical and immunological studies have consistently shown a relationship between atopic diathesis and idiopathic nephrotic syndrome (INS). However, no large population cohort study has yet to demonstrate the nature of the relationship between these disorders. METHODS: Claims data from a random selection of children representing half of the insured population in Taiwan were examined. During the period from 1998 to 2007, we identified 192,295 children aged <18 years with newly diagnosed atopic dermatitis (AD) and 769,169 frequency-matched controls. Incidence of INS and hazard ratios (HRs) were calculated. RESULTS: The AD cohort had a 2-fold higher overall incidence of INS than the non-AD cohort [7.20 vs. 3.60 per 100,000 person-years, respectively; 95 % confidence interval (CI) 1.50-2.66]. The HR for INS increased with age and was higher among females. The HR for INS was also higher in AD children with more medical visits per year, ranging from 0.94 for those having ≤3 visits to 38.6 for those having >6 visits (trend test P < 0.0001). In particular, the risk of INS clearly increased during the initial 5 years after AD onset. CONCLUSIONS: Children with AD have a greater incidence and risk of developing INS and this risk increases with AD severity.

Neuropsychiatric comorbidities in tuberous sclerosis complex patients with epilepsy: results of the TAND checklist survey.

PURPOSE: In addition to epilepsy, individuals with tuberous sclerosis complex (TSC) experience a wide range of behavioral, psychiatric, intellectual, academic, and psychosocial problems. They usually exert a large psychological burden on individuals with these illnesses. METHODS: This cross-sectional study used TSC-associated neuropsychiatric disorders (TAND) checklist interviews conducted at a single medical center. The enrollment of all subjects was > 6 years, and the comorbidities of neurodevelopmental disorders were assessed by clinical psychologists before enrollment. To assess the spectrum of TAND, the TAND checklist was applied as stated in the protocol, and the responses to the TAND checklist were evaluated by clinical psychologists. RESULTS: In the behavioral concerns of patients with TSC without epilepsy, those with epilepsy had excessive shyness, language delay, lack of eye contact, rigid behavior, inattentiveness, and restlessness. In psychiatric disorders, autism spectrum disorder and attention-deficit/hyperactivity disorder are significantly correlated with epilepsy history. Diminished academic skills, including reading, writing, and mathematics skills, are significantly associated with epilepsy history. For intellectual ability, TSC patients without epilepsy is associated normal intelligence level. Among neuropsychological skills, deficits in attention, dual tasking/multi-tasking, visuospatial tasking, and executive skills are significantly associated with epilepsy history. CONCLUSIONS: Epilepsy in patients with TSC contributes to comorbid neuropsychiatric disorders. In addition to epilepsy evaluation, it is crucial to evaluate the heterogeneous spectrum of neuropsychiatric disorders using a standard checklist during the annual clinical follow-up of patients with TSC.
