Human skin is continuously exposed to internal and external influences that may alter its condition and functioning. As a consequence, the skin may undergo alterations leading to immune dysfunction, imbalanced epidermal homeostasis, or other skin disorders. New theories are developing that link food intake and health. The objective of this review is to evaluate current knowledge about the interrelation of food and skin, particularly the effect of nutrients on some cutaneous immune disorders and therapeutic actions of nutrients in skin disorders. 相似文献
Abstract.
Excessive daytime somnolence (EDS) and quality of sleep
were studied in 25 parkinsonian patients at baseline, when they
had not yet received any antiparkinsonian medication, and after
1 year of treatment with dopaminergic drugs. EDS was measured by
the Epworth Sleepiness Scale (ESS) and sleep quality by the
Pittsburgh Sleep Quality Index (PSQI). At baseline, the ESS
score was not different from that of agematched healthy
controls. The mean ESS score increased significantly after 1
year of follow-up, being more than 10 in 12 patients. The mean
PSQI also increased significantly after 1 year of treatment, but
there were no differences in the number of bad sleepers at
baseline and at follow-up. In conclusion, EDS seems to emerge
during the course of the illness, at least in a proportion of PD
patients, and could represent another clinical correlate of the
interaction between the ongoing neurodegenerative process and
the side effects of drugs. 相似文献
The results are reported of our operative experience with 22 cases of external congenital ophthalmoplegia. The familiality, the muscular enzymes and isoenzymes, and often the skeletal electromyography have been studied, with the latter three being significantly altered in most cases. The main indication for surgery is the need to improve the anomalous position of the hyperextended neck. In the presence of inherent ptosis, this is achieved by suspending the upper eyelid from the frontalis muscle by using an autogenous fascia lata. A review of the previously published reports on eyebrow suspension leads one to conclude that autogenous fascia lata is the best material for this purpose. 相似文献
Migraine prevention hinges on a variety of non-specific drugs that mainly reduce neuronal hyperexcitability, the putative pathophysiological hallmark for migraine. The improved knowledge about migraine circuitry and neurobiology has prompted research to develop new specific migraine preventive medications targeted to innovative sites and mechanisms. Drugs designed to inhibit cortical spreading depression, for example tonabersat, might offer a useful option for the management of migraine with aura but not for migraine without aura. Inducible nitric-oxide synthase (iNOS) inhibition seems ineffective as a prophylactic strategy. Results are awaited from recent and ongoing phase II trials with glutamate receptor antagonists, third-generation antiepileptics, melatonin agonists, vitamin D3 and statins. 相似文献
Despite an increased use of non-invasive ventilatory strategies and gentle ventilation, pneumothorax remains a common complication in preterm infants. The ventilator management of infants with air leaks remains challenging in terms of both prevention and treatment. Recently the safety and efficacy of expectant management avoiding chest tube drainage to treat large air leak in preterm infants hemodynamically stable has been reported.
Case presentation
In the present study, we report five cases of preterm infants with birth weight?≤?1250 g affected by respiratory distress syndrome and treated with nasal continuous positive airway pressure as first intention. They were intubated for worsening of respiratory distress with increasing oxygen requirement and concomitant increase of respiratory rate and PCO2 values due to occurrence of pneumothorax, and they were successfully treated using high-frequency oscillatory ventilation without chest tube insertion.
Conclusion
In our experience high-frequency oscillatory ventilation provided a conservative management of a significant pneumothorax in preterm newborns hemodynamically stable and requiring mechanical ventilation. This approach allowed us to avoid the increasing of air leak and the insertion of chest tube drainage and all the subsequent associated risks.
Calcitonin gene-related peptide (CGRP), a potent vasodilator and pain-signaling neuropeptide, is a validated therapeutic target for migraine and cluster headache. Four anti-CGRP monoclonal antibodies (mAbs) have been developed, representing the first specific, mechanism-based, migraine prophylactic treatment. CGRP mAbs demonstrated good efficacy coupled to excellent tolerability and safety in 5 phase II clinical trials. Notably, CGRP mAbs induced complete migraine remission in a patients’ subset. To date, more than 20 phase III trials using CGRP mAbs for of episodic and chronic migraine and cluster headache prevention are ongoing. Future investigations will shed light on migraine endophenotypes predictive of good CGRP mAbs responsiveness and provide answers on their long-term cardiovascular safety. 相似文献
Aim of this study is to verify whether there is concordance between disease’s severity, health-related quality of life (HRQoL)
and disability in patients with Myasthenia gravis (MG). 102 MG patients were clustered on the basis of HRQoL and disability
scores into three groups: low disability and low HRQoL decrement (51 patients), intermediate disability and HRQoL decrement
(28 patients), severe disability and high HRQoL decrement (23 patients). Cross tabulation with symmetric measures (Cramer’s V and Contingency Coefficient) was used to verify the relationships between disease severity groups, based on the Myasthenia
Gravis Foundation of America (MGFA) criteria, and obtained clusters. Results confirm a significant relationship between MG
severity groups, HRQoL and disability profiles. In our opinion, HRQoL and disability instruments should be employed in clinical
trials to match efficacy of treatments, measured on symptoms’ reductions only, with their effects on patients’ disability
and HRQoL. 相似文献
Introduction: Research has focused on serotonin (5-HT) 5-HT1D and 5-HT1F receptors to develop drugs acting through non-vasoconstrictive mechanisms for treating acute migraine and those targeting 5-HT2B and 5-HT7 receptors for preventing migraine.
Areas covered: This paper reviews antimigraine drugs targeting 5-HT receptors in one phase I trial (sumatriptan iontophoretic transdermal system, TDS) and five phase II clinical trials (PNU-142633, LY334370, lasmiditan, NOX-188).
Expert opinion: Data from our overview on investigational drugs in phase I and II clinical trials using the 5-HT1B/1D receptor agonist (sumatriptan TDS), 5-HT1D receptor agonist (PNU-142633), 5-HT1F receptor agonists (LY334370, lasmiditan) and a combined 5-HT1B/1D receptor agonist with nNOS inhibition (NOX-188) provided encouraging data for sumatriptan TDS and lasmiditan, disappointing results for PNU-142633, and promising findings for NOX-188. The 5-HT1F receptor agonist lasmiditan, a drug acting through non-vasoconstrictive mechanisms, represents a promising safe, effective and tolerated acute migraine therapy also for patients at cardiovascular risk. Upcoming phase III trials should clarify the optimal lasmiditan dose and eventual clinical advantages over triptans. The negative results for the PNU-142633 trial prompt further studies using specific compounds more precisely targeting 5-HT1D receptors. Antagonism at 5-HT2B and 5-TH7 receptors, a promising strategy to prevent migraine, is still limited to experimental migraine models. 相似文献
