Purpose of Review
Nutraceuticals are a form of complementary and alternative medicine that is commonly used by children and adolescents with migraine. In this review, observational studies, randomized controlled trials, systematic reviews, and meta-analyses on the efficacy and safety of single compound nutraceuticals for the management of migraine in children and adolescents were identified through a literature search of MEDLINE, Embase, and EBM Reviews—Cochrane Central Register of Controlled Trials.Recent Findings
Twenty-one studies were reviewed, of which 11 were observational studies, 7 were randomized controlled trials, and 3 were systematic reviews. Six different nutraceuticals were included in the review: vitamin D, riboflavin, coenzyme Q10, magnesium, butterbur, and polyunsaturated fatty acids. All but three of the studies assessed the role of nutraceuticals in migraine prevention, while three studies evaluated the role of intravenous magnesium for acute migraine management. Overall, the quality and size of the studies were limited.Summary
Due to low quality evidence and limited studies, no definite conclusions can be drawn on the efficacy of nutraceuticals for the treatment of pediatric migraine. Future studies are warranted in order to establish evidence upon which to define the role of nutraceuticals in this patient population.62.

AIMS: To evaluate trans-abdominal ultrasound for the detection of Hepatocellular carcinoma (HCC) in a bitrasgenic murine (X/myc) model using a commercially available high-frequency ultrasound unit. METHODS: Sixty-one female animals were included in this study. These animals were submitted to a single ultrasound examination of the liver under general anesthesia (isoflurane), and then euthanized. Results of ultrasound were compared with necropsy and histopathology. RESULTS: The lesions demonstrated a fairly consistent aspect (oval- or round-shaped, well-defined hypoechoic homogeneous lesions), and lesions as small as 2 mm were identified. For detection of hepatic nodules per mouse the sensitivity was 75%, the specificity was 100% and the accuracy was 88.5%. For detection of hepatic focal lesions per lesions the overall sensitivity was 60%, the specificity was 97%, and the accuracy was 75.9%. Contrast-enhanced harmonic ultrasound imaging did not improve the identification of the lesions in our experimental conditions. CONCLUSION: High-frequency ultrasound appears to be an efficient tool allowing new possibilities to use this animal model and evaluate new therapies in longitudinal studies, which are much more powerful. 相似文献

Melatonin is synthesized during the night by the pineal gland. Recently, melatonin binding sites have been identified in the gut. Despite few studies, the physiological role of melatonin in gut function remains unclear. The objective of the present study was to investigate the effects of melatonin in the regulation of intestinal motility by using the melatonin receptor antagonist S 22153 in rats. Twenty-four male Wistar rats (400 +/- 25 g) were equipped with intraparietal electrodes along the small intestine. Rats were subjected to a 12:12 hr light:dark schedule. During the dark phase, intestinal migrating motor complexes (MMCs) frequency increased (P < 0.05) by 20% in the duodenum and in the jejunum compared with daylight. This effect is due to a significant reduction in the irregular spiking activity (ISA) of MMCs. Concurrently, at night, the duration of the postprandial motor response is reduced by 30% in the duodenum and 50% in the jejunum and ileum. The administration of S 22153 (2 mg/kg sc) at night suppressed these nocturnal variations and restored the daylight values. In contrast, S 22153 was ineffective during daylight whatever the digestive state. Administration of melatonin (1 mg/kg iv) during the preprandial state, 3 hr after light onset, decreased (-80%) the duration of the ISA of MMCs at the three intestinal levels. During the satiety phase, melatonin administered 10 min before or 15 min after food onset induced the appearance of a transitory preprandial-like motor profile in the entire small intestine. In contrast, when administered at the end of the meal it was ineffective. Preprandial and postprandial melatonin effects were prevented by S 22153 pretreatment. In conclusion, these findings reveal, first, that endogenous melatonin is physiologically involved in the pre- and postprandial changes of intestinal motility at night. Second, exogenous melatonin produces pharmacological effects on pre- and postprandial intestinal motility. In both cases, the action of melatonin corresponds to an inhibition of ISA and a reinforcement of the cyclic MMC pattern. 相似文献

The effect of raw onions on acid reflux and reflux symptoms 总被引:4,自引:0,他引:4

Patients with gastroesophageal reflux often describe heartburn after "spicy meals." One ingredient common to most such meals is onion. We investigated the effects of onion on acid reflux and reflux symptoms in 16 normal subjects and 16 heartburn subjects. Subjects were studied with an esophageal pH probe for 2 h after the ingestion of a plain hamburger and a glass of ice water. The identical meal, with the addition of a slice of onion, was ingested on a counterbalanced day. Variables measured were number of reflux episodes, percentage of the time pH was less than four, heartburn episodes, and belches. Ingestion of onions did not increase any of the reflux variables measured in normals. However, onions significantly increased all measures in heartburn subjects, compared with the no-onion condition, and compared with normals under the onion condition. Onions can be a potent and long-lasting refluxogenic agent in heartburn patients. 相似文献

We report a case of snakebite in which envenomation was manifested through impairment of the visual field. The patient, a 46-year-old man, was bitten on the right thumb by Bothrops lanceolatus. Treatment with a specific equine antivenom (Bothrofav) was administered one hour after the bite. With the exception of fang marks, the results of a clinical examination, particularly the neurologic component, were normal. The day after the bite, the patient developed an inferior left lateral homonymous quadranopsia with macular epargne. T2 magnetic resonance imaging showed a right occipital infarction. His condition improved clinically and biologically. This observation of snakebite is the first in which envenomation was accompanied exclusively by an impairment of the visual field. Envenomation by B. lanceolatus is distinct in its incidence of significant thrombotic complications at a distance from the site of the bite. 相似文献

PURPOSEThe Vienna and Venezia (Elekta) are hybrid intracavitary/interstitial brachytherapy (BT) applicators for cervical cancers unsuitable for intracavitary BT alone to improve target coverage or reduce critical organ dose. There is limited outcome data with the use of these applicators outside published experience of the EMBRACE group. We report feasibility and early outcomes with the use of these hybrid applicators at our institution.METHODS AND MATERIALSHybrid applicators were used to treat 61 patients with cervical cancer from November 2011 to December 2019. Indications for hybrid applicator use were involvement of the vagina in 10 patients (16%), residual central or parametrial disease in 46 patients (75%), and a narrow introitus in 5 patients (9%). Toxicities were graded using the CTCAE v4.0. Outcomes were assessed with the Kaplan–Meier method.ResultsMedian follow-up was 16 months (IQR 9–32 mos). Median HRCTV volume was 31.6 cm3 (IQR 25–48 cm3). Median HRCTV D90 was 86.1 Gy (IQR 84.3–88.0 Gy). In 54 patients with follow-up PET/CT at 3 months, complete initial imaging response locally was seen in 46 patients.Estimated 12-month Kaplan–Meier overall survival, locoregional control, distant control, and recurrence-free survival estimates were 86.9%, 80.6%, 73.8%, and 65.9%, respectively. The 12-month incidence of Grade 3+ GI/GU chronic toxicities was 5.7%, consisting of vesicovaginal fistula, rectovaginal fistula, and ureterovesical fistula.ConclusionsOur single-institution data support the use of the hybrid applicators, as an alternative to traditional BT applicators when clinically warranted. Use of hybrid applicators is feasible with adequate coverage of disease in the vagina and parametrium. 相似文献
