Rationale Although clinical practice guidelines recommend that management of moderate to severe spasticity include the use of botulinum toxin-A in conjunction with therapy, there is currently no evidence to support the addition of therapy. Aims To determine the effect and cost-benefit of adding evidence-based movement training to botulinum toxin-A. Sample size estimate A total of 136 participants will be recruited in order to be able to detect a between-group difference of seven points on the Goal Attainment Scale T-score with 80% power at a two-tailed significance level of 0...

BACKGROUND: Antipsychotic (neuroleptic) medication is used extensively to treat people with chronic mental illnesses. Its use, however, is associated with adverse effects, including movement disorders such as tardive dyskinesia (TD) - a problem often seen as repetitive involuntary movements around the mouth and face. This review, one in a series examining the treatment of TD, covers miscellaneous treatments not covered elsewhere. OBJECTIVES: To determine whether drugs, hormone-, dietary-, or herb-supplements not covered in other Cochrane reviews on TD treatments, surgical interventions, electroconvulsive therapy, and mind-body therapies were effective and safe for people with antipsychotic-induced TD...

Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced melanoma. The first ICI to demonstrate clinical benefit, ipilimumab, targets cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4); however, the long-term overall survival is just 22%. More than 40 years ago intralesional (IL) bacillus Calmette-Guérin (BCG), a living attenuated strain of Mycobacterium bovis , was found to induce tumor regression by stimulating cell-mediated immunity following a localized and self-limiting infection...

Although potent effects of psychoactive drugs on circadian rhythms were first described over 30 years ago, research into the reciprocal relationship between the reward system and the circadian system - and the impact of this relationship on addiction - has only become a focus in the last decade. Nonetheless, great progress has been made in that short time toward understanding how drugs of abuse impact the molecular and physiological circadian clocks, as well as how disruption of normal circadian rhythm biology may contribute to addiction and ameliorate the efficacy of treatments for addiction...

BACKGROUND/AIMS: Lubeluzole is a benzothiazole derivative that has shown neuroprotective properties in preclinical models of ischemic stroke. However, clinical research on lubeluzole is now at a standstill, since lubeluzole seems to be associated with the acquired long QT syndrome and ventricular arrhythmias. Since the cardiac cellular effects of lubeluzole have not been described thus far, an explanation for the lubeluzole-induced QT interval prolongation is lacking. METHODS: We tested the affinity of lubeluzole, its enantiomer, and the racemate for hERG channel using the patch-clamp technique...

INTRODUCTION: Benign metastasizing leiomyomas represent benign lesions consisted by leiomatosous tissue and could be observed in positions away from their usual localization, the human uterus. They commonly affect women that have undergone total hysterectomy. Approximately 100 similar cases have been reported in the literature, so the case we present is rare and reviewing the literature and needs to be reported. PRESENTATION OF CASE: We report a case of a 55 year old Greek woman, gravida five and para three, who attended our unit 3 years ago complaining of occasionally lower abdominal pain and irritation the last months...

Coadaptation between mistletoes and birds captured the attention of Charles Darwin over 150 years ago, stimulating considerable scientific research. Here we used Loranthaceae, a speciose and ecologically important mistletoe family, to obtain new insights into the interrelationships among its hosts and dispersers. Phylogenetic analyses of Loranthaceae were based on a dataset of nuclear and chloroplast DNA sequences. Divergence time estimation, ancestral area reconstruction, and diversification rate analyses were employed to examine historical biogeography...

INTRODUCTION: 10 years ago, Meston and Buss (Arch Sex Behav 2007;36:477-507) identified 237 reasons for having sex. Since then, only a few studies have built on the analyses of differences in sexual motivation. AIM: To replicate the YSEX? in a broader sample of women and men of different ages. METHODS: Women and men younger than 18 (n = 141), 18 to 22 (n = 1,039), 22 to 55 (n = 2,804), and at least 55 (n = 667) years old completed an online survey about their reasons for engaging in sex during the past year...

Fifteen years ago Olney and colleagues began using animal models to evaluate the effects of anesthetic and sedative agents (ASAs) on neurodevelopment. The results from ongoing studies indicate that, under certain conditions, exposure to these drugs during development induces an acute elevated apoptotic neurodegenerative response in the brain and long-term functional impairments. These animal models have played a significant role in bringing attention to the possible adverse effects of exposing the developing brain to ASAs when few concerns had been raised previously in the medical community...

USP6, also known as Tre-2 and TRE17, is an ubiquitase-specific proteinase that was identified more than two decades ago as a potential oncogene when it exhibited transforming properties upon overexpression in NIH 3T3 cells. Until recently, however, little was known about the function and the oncogenetic activation of USP6. The identification of rearrangements of the USP6 gene in aneurysmal bone cyst and in nodular fasciitis has not only led to a better understanding of the pathogenesis of these entities, but is also a useful tool in their diagnosis and differential diagnostic delineation from morphological mimics...

BACKGROUND: Opioid prescribing has been increasingly scrutinized among non-cancer patients. As an unintended consequence, opioids may be under-prescribed for cancer patients. The purpose of this study was to compare trends in opioid prescribing in younger adults with and without cancer. METHODS: From 2004 to 2013, Ontario residents 18-64 years eligible for government paid pharmacare were annually stratified into 3 groups: no cancer history, cancer diagnosis >5 years ago and cancer diagnosis ≤5 years ago...

The marine environment around Japan experienced significant changes during the Cenozoic Era. In this study, we report findings suggesting that this dynamic history left behind traces in the genome of the Japanese sand dollar species Peronella japonica and P. rubra. Although mitochondrial Cytochrome C Oxidase I sequences did not indicate fragmentation of the current local populations of P. japonica around Japan, two different types of intron sequence were found in the Alx1 locus. We inferred that past fragmentation of the populations account for the presence of two types of nuclear sequences as alleles in the Alx1 intron of P...

INTRODUCTION: In recent years, the early detection and treatment of the first episode of schizophrenia (FES) has attracted worldwide attention. In Japan, psychiatric care has changed to an open and accessible framework over the past decade. Therefore, the duration of untreated psychosis (DUP) is thought to have been shortened. The purposes of this study were to investigate whether recent DUP periods are shorter than they were 10 years ago and whether the DUP at present differs among psychiatric facilities...

Amidst the NHS's (National Health Service) success lies its major weakness, although one that Klein overlooks in his reflections on the NHS as it approaches 70. The focus on, and investment in, curing ill-health has been at the expense of attending to the public's overall health and well-being. This preoccupation poses a greater threat to the NHS's future than privatisation. Despite the weakness having been diagnosed decades ago, redressing the imbalance has proved stubbornly hard to achieve. Rhetoric has not been translated into reality...

Until six decades ago, death was considered to be a specific point in time, referring to the moment at which life ends. With the availability of ventilators, even determining when death has occurred is becoming difficult, as cessation of life functions is often not simultaneous across organ systems. With increasing accessibility to intensive care units (ICUs) even in Tier II and Tier III cities, and the government making it mandatory to notify brain death to facilitate cadaveric organ transplants, it behooves the neurosurgeon and neurologist to totally understand the minutiae of brain death...

Two landmark trials conducted more than 35 years ago provided scientific evidence that, under very specific circumstances, long-term oxygen therapy (LTOT) may prolong life. These two trials enrolled 290 patients with chronic obstructive pulmonary disease (COPD) and severe daytime hypoxemia documented by direct arterial blood gas measurement. From this moment, LTOT became a standard of care and the indications for oxygen therapy have expanded to include nocturnal oxygen therapy for isolated nocturnal oxygen desaturation, ambulatory oxygen to correct exercise-induced desaturation, and short-burst oxygen to relieve dyspnea...

50 years ago, Northway described Broncopulmonary Dysplasia (BPD) in preterm infants exposed to mechanical ventilation. Since then, their survival has increased, nevertheless a "new BPD" has appeared and its incidence has not diminished. One of the characteristics of this pathology is the the abnormal vascular remodeling, which in its most severe expression is known as Pulmonary Hyper tension (PH); with an incidence of 17% in patients with BPD, which is proportional to the severity of the disease (33% in severe BPD), and as mortality factor (up to 48% 2-year mortality in PH-BPD)...

The ability to understand in great details, at the molecular level, the process of myelination in the peripheral nervous system (PNS) is, in no minor part, due to the availability of an in vitro culture model of PNS myelination. This culture system is based on the ability to prepare large population of highly purified Schwann cells and dorsal root ganglia neurons that, once co-cultured, can be driven to form in vitro well-defined myelinated axon units. In this chapter, we present our detailed protocols to establish these cell cultures that are derived from modifications of procedures developed 35-40 years ago...

Delgado-Baquerizo et al . ( Science Advances , 12 April 2017, e1602008) use statistical correlations to infer that paleoclimate (6000 to 22,000 years ago) is a more important driver of current soil organic carbon stocks than the current-day climate. On the other hand, a wealth of radiocarbon measurements indicates that the organic carbon in most topsoils is only a few decades to perhaps a few centuries old. These seemingly incongruous results can perhaps be reconciled by considering that the long-term pedogenic development of a soil strongly influences the physiochemical properties, which lead to stabilization of new carbon entering that soil regardless of current climate...

A 41-year-old female presented to the hospital with sore throat and shortness of breath. She was hypoxic with an oxygen saturation of 87% in room air. Physical examination revealed swollen uvula with exudates. She had been started on topiramate for treatment of migraine few months ago. The dose of topiramate was increased to 100 mg twice daily 2 weeks ago. Complete blood count revealed an absolute neutrophil count (ANC) of 8 c/mm3 . She was intubated and started on broad-spectrum antibiotics. She was transferred to our hospital on the fifth day of hospitalization...
