The use of complementary and alternative medicine in children with common neurologic diseases
Complementary and alternative medicine (CAM) is a phrase used to describe additional health care methods such as mind/body practices and natural products not regarded as treatments by conventional medicine. The use of CAM in children with common neurologic diseases is more frequent than its use in healthy children (24%â78% vs. 12%). However, less than half of patients report such use to their physicians. The preferred modalities of CAM vary in different countries due to their different cultures and traditions. The most common factor significantly associated with the use of CAM is parental CAM use in most studies. The frequency of the use of CAM in children and adults with neurologic diseases is similar, and both rates are higher than the rates in those without these conditions. The preferred modalities of CAM in adults are diverse, and megavitamins and mind/body therapy (prayer and chiropractic care) are included. The most common factor significantly associated with the use of CAM in adults with neurologic diseases is high educational level. Physicians need to be concerned with patients' use of CAM and provide correct information about CAM so that patients may make the right decisions. Further study is needed to determine the evidence-based efficacy of CAM use in children with common neurologic diseases
Palladium Catalysts for Dehydrogenation of Ammonia Borane with Preferential BâH Activation
Cationic Pd(II) complexes catalyzed the dehydrogenation of ammonia borane in the most efficient manner with the release of 2.0 equiv of H_2 in less than 60 s at 25 °C. Most of the hydrogen atoms were obtained from the boron atom of the ammonia borane. The first step of the dehydrogenation reaction was elaborated using density functional theory calculations
Venous angioma may be associated with epilepsy in children
PurposeVenous angioma (VA) is the most common congenital abnormality of the intracranial vasculature. This study aimed to investigate the relationship between VA and epilepsy and to identify the characteristics of children with VA and epilepsy.MethodsThe records of all patients aged less than 18 years who underwent brain magnetic resonance imaging (MRI) at Pusan National University Hospital were retrospectively reviewed. Patients with isolated VA and patients with normal MRI were compared in terms of the prevalence of epilepsy.ResultsIn total, 2,385 pediatric patients who underwent brain MRI were enrolled. Isolated VA was identified in 26 patients (VA group). Among the patients with normal MRI findings, 225 age- and sex-matched patients to the VA-group were assigned to the control group. Nine patients in the VA group (9 of 26, 34.6%) and 27 patients in the control group (26 of 225, 11.5%; P<0.001) had epilepsy. In the VA group, 20 patients (76.9%) had the VA in the cerebral hemispheres, and 6 patients (23.1%) had the VA in the brainstem and cerebellum. The latter showed a higher prevalence of epilepsy (5 of 6, 83.3%) than the former (4 of 20, 20.0%; P=0.004). Among the nine patients who had epilepsy with VA, patients whose VA involved the brainstem and cerebellum showed a significantly higher frequency of abnormal Electroencephalographic findings than patients whose VA involved the cerebral hemispheres (P=0.016).ConclusionVA, especially in the brainstem and cerebellum, might be associated with epilepsy
Real-Life Efficacy and Tolerability of Lacosamide in Pediatric Patients Aged 4 Years or Older with Drug-Resistant Epilepsy
Purpose The aim of this study was to evaluate the efficacy and safety of adjunctive lacosamide therapy in pediatric patients aged â„4 years with drug-resistant epilepsy (DRE). Methods Medical records of children aged 4 to 19 years treated with lacosamide as adjunctive therapy for DRE were retrospectively reviewed. The patients were divided into two groups according to their age at the start of lacosamide treatment: group A (aged 4â15 years) and group B (aged 16â19 years). Changes in seizure frequency from baseline, adverse events, and the retention rate were evaluated at each follow-up visit. Results Sixty-two patients (33 males and 29 females) with a mean age of 11.4 years (range, 4 to 19) were included. The mean duration of follow-up was 20.1±12.9 months. The mean maintenance dose of lacosamide was 6.7±4.8 mg/kg/day. Forty-two patients (67.7%) were responders (â„50% reduction in seizures) with 19.4% (12/62) achieving freedom from seizures. The response rate did not differ significantly between groups A and B (67.6% vs. 68.0%, P=0.795) and was not affected by the concomitant use of sodium channel blockers. Significant independent factors associated with a good response to lacosamide treatment were a shorter duration of epilepsy (P=0.035) and fewer concomitant anti-seizure medications (P=0.002). Mild transient adverse events were observed in 20 patients (32.3%). Conclusion Lacosamide adjunctive therapy was efficacious and tolerated in children aged â„4 years with DRE. Early use of lacosamide may be helpful for a good response to drug-resistant seizures
Partial Trisomy 1q41 Syndrome Delineated by Whole Genomic Array Comparative Genome Hybridization
Partial trisomy 1q syndrome is a rare chromosomal abnormality. We report on a male infant with 46,XY,der(11)t(1;11)(q41;p15.5) due to unbalanced segregation of the maternal reciprocal balanced translocation 46,XX,t(1;11)(q41;p15.5). The baby presented with a mild phenotype, characterized by a triangular face, almond-shaped eyes, low ears, short stature with relatively long legs, and mild psychomotor retardation. We utilized whole genomic array comparative genome hybridization (CGH) with 4,000 selected bacterial artificial chromosomes (BACs) to define the chromosomal breakpoints and to delineate the extent of the partial trisomy in more detail. To our knowledge, this is the first case of nearly pure "partial trisomy 1q41" defined by whole genomic array CGH
A Carcinoembryonic Antigen-Secreting Adenocarcinoma Arising in Tailgut Cyst : Clinical Implications of Carcinoembryonic Antigen
Tailgut cysts (TGCs) are rare congenital cysts that occur in the retrorectal or presacral spaces. Although most tailgut cysts have been reported as benign, there have been at least 9 cases associated with malignant change. We report herein on an unusual case of a 40-year-old woman with a carcinoembryonic antigen (CEA)-producing adenocarcinoma arising within a TGC who underwent surgical resection and local radiation therapy. Despite the complete resection, metastatic adenocarcinoma developed five months after surgery. CEA-producing adenocarcinoma from a TGC is extremely rare and only two cases, including this case, have been reported in the English medical literature. Besides CEA, the serum levels of CA 19-9 became markedly elevated in this patient. Given that the serum CEA level decreased to the normal range after complete resection of tumor and that the tumor recurrence was associated with a rebound of the CEA serum level, our case shows that serial measurements of serum CEA can be used for treatment planning and for assessing the patient's treatment response for this rare disease
SEALONE (Safety and Efficacy of Coronary Computed Tomography Angiography with Low Dose in Patients Visiting Emergency Room) trial: study protocol for a randomized controlled trial
Objective Chest pain is one of the most common complaints in the emergency department (ED). Cardiac computed tomography angiography (CCTA) is a frequently used tool for the early triage of patients with low- to intermediate-risk acute chest pain. We present a study protocol for a multicenter prospective randomized controlled clinical trial testing the hypothesis that a low-dose CCTA protocol using prospective electrocardiogram (ECG)-triggering and limited-scan range can provide sufficient diagnostic safety for early triage of patients with acute chest pain. Methods The trial will include 681 younger adult (aged 20 to 55) patients visiting EDs of three academic hospitals for acute chest pain or equivalent symptoms who require further evaluation to rule out acute coronary syndrome. Participants will be randomly allocated to either low-dose or conventional CCTA protocol at a 2:1 ratio. The low-dose group will undergo CCTA with prospective ECG-triggering and restricted scan range from sub-carina to heart base. The conventional protocol group will undergo CCTA with retrospective ECG-gating covering the entire chest. Patient disposition is determined based on computed tomography findings and clinical progression and all patients are followed for a month. The primary objective is to prove that the chance of experiencing any hard event within 30 days after a negative low-dose CCTA is less than 1%. The secondary objectives are comparisons of the amount of radiation exposure, ED length of stay and overall cost. Results and Conclusion Our low-dose protocol is readily applicable to current multi-detector computed tomography devices. If this study proves its safety and efficacy, dose-reduction without purchasing of expensive newer devices would be possible
Palladium Catalysts for Dehydrogenation of Ammonia Borane with Preferential BâH Activation
A neonate with Joubert syndrome presenting with symptoms of Horner syndrome
Joubert syndrome (JS) is characterized by the âmolar tooth signâ (MTS) with cerebellar vermis agenesis, episodic hyperpnea, abnormal eye movements, and hypotonia. Ocular and oculomotor abnormalities have been observed; however, Horner syndrome (HS) has not been documented in children with JS. We present the case of a 2-month-old boy having ocular abnormalities with bilateral nystagmus, left-dominant bilateral ptosis, and unilateral miosis and enophthalmos of the left eye, which were compatible with HS. Brain magnetic resonance imaging (MRI) revealed the presence of the MTS. Neck MRI showed no definite lesion or mass around the cervical sympathetic chain. His global development was delayed. He underwent ophthalmologic surgery, and showed some improvement in his ptosis. To the best of our knowledge, the association of HS with JS has not yet been described. We suggest that early neuroimaging should be considered for neonates or young infants with diverse eye abnormalities to evaluate the underlying etiology
