刘晓鹰教授“扶中”外治法治疗儿科疾病临床经验浅析

小儿"脾常不足",脾胃之体成而未全,脾胃之气全而未壮,脾胃不足在儿科疾病发生发展、病机转归中占有相当重要的地位。刘晓鹰教授在继承全国名老中医倪珠英学术思想基础上,提出"扶中"外治法,立法取穴方面强调时时顾护小儿中焦脾胃,采用小儿推拿、扶阳罐(含温推、温灸和温刮痧)、针刺(含腹针、揿针)等外治手段治疗儿科脾、肺、肾等系列疾病,取得满意疗效。     

Flavin adenine dinucleotide synthase deficiency due to FLAD1 mutation presenting as multiple acyl-CoA dehydrogenation deficiency-like disease: A case report

Multiple acyl-CoA dehydrogenase deficiency (MADD), also known as glutaric acidemia type II, is classically caused by a congenital defect in electron transfer flavoprotein (ETF) or ETF dehydrogenase (ETFDH). Flavin adenine dinucleotide synthase (FADS) deficiency caused by mutations in FLAD1 was recently reported as a novel riboflavin metabolism disorder resembling MADD. Here, we describe a Japanese boy with FADS deficiency due to a novel mutation (p.R249*) in FLAD1. In the asymptomatic male infant born at full term, newborn screening showed positive results with elevated C5 and C14:1 acylcarnitine levels and an increased C14:1/C2 ratio. Biochemical studies were unremarkable except for lactic acidosis (pH 7.197, lactate 61 mg/dL). A diagnosis of MADD was suspected because of mild abnormalities of the acylcarnitine profile and apparent abnormalities of urinary organic acids, although mutations in the ETFA, ETFB, ETFDH, and riboflavin transporter genes (SLC52A1, SLC52A2, and SLC52A3) were not detected. Administration of riboflavin and L-carnitine was initiated at one month of age based on the diagnosis of “biochemical MADD” despite a lack of symptoms. Nevertheless, the acylcarnitine profile was not normalized. Symptoms resembling bulbar palsy, such as vocal cord paralysis and dyspnea with stridor, were present from 3 months of age. At 4 months of age, he became bedridden because of hypoxic-ischemic encephalopathy due to fulminant respiratory failure with aspiration pneumonia. At 2 years and 5 months of age, a homozygous c.745C > T (p.R249*) mutation in the FLAD1 gene was identified, confirming the diagnosis of FADS deficiency. His severe clinical course may be caused by this nonsense mutation associated with poor responsiveness to riboflavin. Persistent lactic acidosis and neuropathy, such as bulbar palsy, may be important for diagnosing FADS deficiency. Although the biochemical findings in FADS deficiency are similar to those in MADD, their clinical symptoms and severity may not be identical.     

Unusual localization and aggressive progression of large infantile fibrosarcoma

Infantile fibrosarcoma is a very rare soft tissue tumor in infants and children most commonly located in extremities. It constitutes less then 1 percent of all childhood cancers. Prognosis and clinical course of it is relatively good compared to adult forms. Local recurrence is common but metastasis is infrequent.In this case report we present infantile fibrosarcoma with relapse and lung metastasis despite neoadjuvant chemotherapy, pelvic reconstruction surgery with wide surgical excision and adjuvant chemotherapy protocol. The patient was a 2-year-old girl at the time of diagnosis, and there was a huge mass in pelvic region. After neoadjuvant chemotherapy, type 1 pelvic resection and pelvic reconstruction with bone cement performed. The patient presented with relapse and lung metastasis 6 months after the surgery.This is the first report of pelvic infantile fibrosarcoma with pelvic resection surgery. This case suggests that these tumors may exhibit unpredictable clinical behavior.

Atenolol oral en el manejo del hemangioma infantil: serie de casos de 46 pacientes

Propranolol, a non-selective beta-blocker, remains the first line of treatment for problematic infantile hemangioma. However, although rarely, a subset of patients experience undesirable side effects, raising interest in other selective beta-blockers. We present a large case series of 46 infants treated successfully with oral atenolol, a selective beta-1 blocker.     

Co-occurring WARS2 and CHRNA6 mutations in a child with a severe form of infantile parkinsonism

ObjectiveTo investigate the molecular cause(s) underlying a severe form of infantile-onset parkinsonism and characterize functionally the identified variants.MethodsA trio-based whole exome sequencing (WES) approach was used to identify the candidate variants underlying the disorder. In silico modeling, and in vitro and in vivo studies were performed to explore the impact of these variants on protein function and relevant cellular processes.ResultsWES analysis identified biallelic variants in WARS2, encoding the mitochondrial tryptophanyl tRNA synthetase (mtTrpRS), a gene whose mutations have recently been associated with multiple neurological phenotypes, including childhood-onset, levodopa-responsive or unresponsive parkinsonism in a few patients. A substantial reduction of mtTrpRS levels in mitochondria and reduced OXPHOS function was demonstrated, supporting their pathogenicity. Based on the infantile-onset and severity of the phenotype, additional variants were considered as possible genetic modifiers. Functional assessment of a selected panel of candidates pointed to a de novo missense mutation in CHRNA6, encoding the α6 subunit of neuronal nicotinic receptors, which are involved in the cholinergic modulation of dopamine release in the striatum, as a second event likely contributing to the phenotype. In silico, in vitro (Xenopus oocytes and GH4C1 cells) and in vivo (C. elegans) analyses demonstrated the disruptive effects of the mutation on acetylcholine receptor structure and function.ConclusionOur findings consolidate the association between biallelic WARS2 mutations and movement disorders, and suggest CHRNA6 as a genetic modifier of the phenotype.     

Effect of interictal epileptiform discharges on EEG-based functional connectivity networks

ObjectiveFunctional connectivity networks (FCNs) based on interictal electroencephalography (EEG) can identify pathological brain networks associated with epilepsy. FCNs are altered by interictal epileptiform discharges (IEDs), but it is unknown whether this is due to the morphology of the IED or the underlying pathological activity. Therefore, we characterized the impact of IEDs on the FCN through simulations and EEG analysis.MethodsWe introduced simulated IEDs to sleep EEG recordings of eight healthy controls and analyzed the effect of IED amplitude and rate on the FCN. We then generated FCNs based on epochs with and without IEDs and compared them to the analogous FCNs from eight subjects with infantile spasms (IS), based on 1340 visually marked IEDs. Differences in network structure and strength were assessed.ResultsIEDs in IS subjects caused increased connectivity strength but no change in network structure. In controls, simulated IEDs with physiological amplitudes and rates did not alter network strength or structure.ConclusionsIncreases in connectivity strength in IS subjects are not artifacts caused by the interictal spike waveform and may be related to the underlying pathophysiology of IS.SignificanceDynamic changes in EEG-based FCNs during IEDs may be valuable for identification of pathological networks associated with epilepsy.
