Neuroleptic malignant syndrome (NMS) is one of the most severe iatrogenic emergencies in clinical service. The symptoms including sudden consciousness change, critical temperature elevation and electrolytes imbalance followed by mutli-organ system failure were common in NMS. In addition to aggressive interventions with intravenous fluid resuscitation and antipyretics, several antidotes have been suggested to prevent further progression of the muscle damage. Dantrolene has been reported to be one of the most effective treatments for NMS...

Vascular mimicry (VM) refers to the plasticity of aggressive cancer cells forming de novo vascular networks, which promoted tumor metastasis. The aim of this study was evaluate the impact of VM on recurrence-free survival (RFS) in urothelial carcinoma of the bladder (UCB). Records from 202 patients treated with radical cystectomy (RC) for UCB at Zhongshan Hospital between 2002 and 2014 were reviewed. The presence of VM was identified by CD31-PAS double staining. Positive VM staining occurred in 19.3% (39 of 202) UCB cases, and it was associated with increased risks of recurrence (Log-Rank p<0...

BACKGROUND: Management of keloids has remained a conundrum, because an optimum treatment regimen has yet to be elucidated. Currently, treatment varies widely between more conservative measures, such as steroid injections, topical medications, and silicone sheeting, to more aggressive options, such as surgery and postoperative radiation. The latter combination has been touted to have superior results, with the lowest rates of pathologic scar recurrence. METHODS: We performed a retrospective review to critically evaluate the effectiveness of surgical excision and radiation treatment in patients with keloids...

Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare form of preinvasive lung lesion associated with indolent carcinoid tumor formation. This disease is characterized by multiple small pulmonary nodules with low SUVmax on F-FDG PET. Biopsy and immunohistochemical staining for neuroendocrine markers confirm diagnosis. There is no consensus for treatment, which typically involves surgical excision or management of symptoms with steroid-based therapies. We report an unusual case of DIPNECH colocalizing with necrotizing granulomatous inflammation mimicking high-grade aggressive malignancy on FDG-PET and a typical case of DIPNECH for comparison with low FDG avidity...

Diagnosis and management of hematopoietic cell transplant-associated thrombotic microangiopathy (TA-TMA) are very complex and controversial, given multiple ongoing issues and comorbidities in sick transplant recipients. Complement activation via classic and alternative pathways is emerging as a potential pathogenetic mechanism in the development of TA-TMA. Complement-centric diagnostic strategy using functional and genetic tests may possibly support diagnosis, enhance molecular understanding and direct drug development...

Metastatic melanoma is a highly aggressive skin cancer with a poor prognosis. It is the leading cause of skin cancer deaths with a median overall survival for advanced-stage metastatic disease of <6 months. Despite advances in the field with conventional and targeted therapies, the heterogeneity of melanoma poses the greatest ongoing challenge, ultimately leading to relapse and progression to a more drug-resistant tumor in most patients. Particularly noteworthy are recent findings, indicating that these therapies exert selective pressure on tumors resulting in the activation of pathways associated with cancer stem cells that are unresponsive to current therapy...

Extensive research is dedicated to understanding if sporadic and familial papillary thyroid carcinoma are distinct biological entities. We have previously demonstrated that familial papillary thyroid cancer (fPTC) cells exhibit short relative telomere length (RTL) in both blood and tissues and that these features may be associated with chromosome instability. Here, we investigated the frequency of HER2 (Human Epidermal Growth Factor Receptor 2) amplification, and other recently reported genetic alterations in sporadic PTC (sPTC) and fPTC, and assessed correlations with RTL and BRAF mutational status...

In this article, a novel driving behavior recognition system based on a specific physical model and motion sensory data is developed to promote traffic safety. Based on the theory of rigid body kinematics, we build a specific physical model to reveal the data change rule during the vehicle moving process. In this work, we adopt a nine-axis motion sensor including a three-axis accelerometer, a three-axis gyroscope and a three-axis magnetometer, and apply a Kalman filter for noise elimination and an adaptive time window for data extraction...

Nitric oxide (NO) produced by nitric oxide synthase (NOS) enzymes is a free radical molecule involved in a wide variety of normophysiologic and pathophysiologic processes. Included in the latter category are cancer promotion, progression, and resistance to therapeutic intervention. Animal tumor photodynamic therapy (PDT) studies several years ago revealed that endogenous NO can reduce PDT efficacy and that NOS inhibitors can alleviate this. Until relatively recently, little else was known about this anti-PDT effect of NO, including: (a) the underlying mechanisms; (b) type(s) of NOS involved; and (c) whether active NO was generated in vascular cells, tumor cells, or both...

Brain tumors are the leading cause of cancer-related deaths in children, and medulloblastoma is the most prevalent malignant childhood/pediatric brain tumor. Providing effective treatment for these cancers, with minimal damage to the still-developing brain, remains one of the greatest challenges faced by clinicians. Understanding the diverse events driving tumor formation, maintenance, progression, and recurrence is necessary for identifying novel targeted therapeutics and improving survival of patients with this disease...

INTRODUCTION: The cricopharyngeal achalasia is an esophageal motor disorder that entails a lack of relaxation of the upper esophageal sphincter. It is rare in children and its etiology is related to multiple factors. The symptoms are nonspecific and may be masked by other diseases. CLINICAL CASE: Report two infants with dysphagia and choking episodes. Upper gastrointestinal series confirmed cricopharyngeal achalasia. The first patient was treated with endoscopic dilatation, and did not require further therapies...

BACKGROUND: Controversial results have shown a significant association with either low or high total testosterone (tT) levels and high risk prostate cancer (PCa). We tested the relationship between circulating tT and grade group 5 (G5) PCa at radical prostatectomy (RP) in patients with preoperative low- to intermediate-risk disease. METHODS: Serum sex hormones were assessed the day before RP in a cohort of 846 patients with low- to intermediate-risk PCa. Patients were segregated using the new 5-tiered Gleason grade groups...

Malamuth's (1998) confluence model holds that the combination of hostile masculinity, impersonal sexuality, and the constellation of high dominance and low nurturance plays a crucial role in explaining men's sexual aggression against women. Most studies on the confluence model concentrate on hostile masculinity and impersonal sexuality rather than dominance and nurturance. Using a person-centered approach, we investigated whether sexual aggressive men could be better identified in a sample of 692 men when not only hostile masculinity and impersonal sexuality but also dominance and nurturance were used as indicators in a latent profile analysis...

Deletion or mutation of the gene encoding the deubiquitinating enzyme CYLD is a common genomic aberration in multiple myeloma (MM). However, the functional consequence of CYLD loss and the mechanism underlying its putative role as a tumor suppressor gene in the pathogenesis of MM has not been established. Here, we show that CYLD expression is highly variable in myeloma cell lines and primary MMs and that low CYLD expression is associated with disease progression from monoclonal gammopathy of undetermined significance to MM, and with poor overall and progression free-survival of MM patients...

Males in a number of group-living species fight in intergroup conflicts to defend access to food resources, a seemingly paradoxical behaviour, given that this resource does not usually limit male fitness directly. We investigated the mechanism(s) driving apparent male food defence in wild vervet monkeys (Chlorocebus aethiops pygerythrus) by testing the effect that female resource access, and female audience size and activity had on the response of focal males during simulated intergroup encounters. Males do not appear to defend food to increase the reproductive success of female group members because their response was not influenced by the presence of provisioning boxes that only females could access...

BACKGROUND: Mental health profiles differ between boys and girls from puberty onwards. It is not known whether differences also extend to symptom presentation in schizophrenia spectrum disorders. It may be that girls and boys are not treated entirely equally by the professionals. AIMS: To study gender differences in symptom profiles, family adversities, pathway to care, and characteristics of inpatient treatment at the first episode of diagnosed schizophrenia spectrum disorder (F20-29) among adolescents aged 13-17...
