The antivascular endothelial growth factor antibody, bevacizumab, is effective against several malignancies in adults but unproven in pediatric oncology. In early phase pediatric studies toxicities were similar to those in adults. Bowel perforation in adults is a rare but serious toxicity, but has not been hitherto reported in children. A 5-year-old boy with chemoresistant neuroblastoma treated with bevacizumab plus radioimmunotherapy developed acute abdominal pain. Computed tomography scan showed free abdominal air and pneumatosis coli...

Aortic dissection is the most catastrophic clinical condition that involves the aorta. It has a high mortality as well as high rate of misdiagnosis due to frequent unusual presentation. Typically, it presents with acute chest, back, and tearing abdominal pain. However, it can present atypically with minimal or no pain, making diagnosis difficult. Physicians should always suspect acute aortic dissection in patients with certain clinical conditions like difficult-to-control hypertension, giant cell arteritis, bicuspid aortic valve, intracranial aneurysms, simple renal cysts, family history of aortic disease, and Marfan syndrome, especially when a patient presents with ischemic symptoms involving multiple organ without an obvious cause...

Spontaneous coronary artery dissection is a very rare cause of acute coronary syndromes and can be life threatening given the rarity of the condition. It should be part of differentials in young females presenting with acute coronary syndromes without routine risk factors for coronary artery disease, especially before, during, and after pregnancy. It is closely associated with fibromuscular dysplasia and management can be very challenging at times. We present a case of spontaneous coronary artery dissection presenting with recurrent ST segment elevation myocardial infarction in association with fibromuscular dysplasia...

BACKGROUND: Caffeine's properties as an analgesic adjuvant with nonsteroidal anti-inflammatory drugs/acetaminophen are well documented. However, little clinical research has explored caffeine's effects on opioid analgesia. This study assessed the effects of caffeine consumption on pain and other symptoms in opioid-using and nonusing chronic pain patients meeting the survey criteria for fibromyalgia. MATERIALS AND METHODS: Patients presenting to a university-based pain clinic completed validated self-report questionnaires assessing symptoms...

BACKGROUND: Empirical evidence suggests that affective responses to pain are changed in chronic pain. The investigation of startle responses to pain might contribute to clarifying whether such alterations also expand to motivational defensive reactions. We aimed at comparing startle responses to tonic heat pain with high threat (HT) or low threat (LT) in patients with chronic musculoskeletal pain and controls. As pain-related anxiety and catastrophizing are typically elevated in chronic pain, we expected to find stronger startle responses in patients specifically under experimental HT...

Submarine volcanic eruptions are major catastrophic events that allow investigation of the colonization mechanisms of newly formed seabed. We explored the seafloor after the eruption of the Tagoro submarine volcano off El Hierro Island, Canary Archipelago. Near the summit of the volcanic cone, at about 130 m depth, we found massive mats of long, white filaments that we named Venus's hair. Microscopic and molecular analyses revealed that these filaments are made of bacterial trichomes enveloped within a sheath and colonized by epibiotic bacteria...

Ecosystems can experience catastrophic transitions to alternative states, yet recent results have suggested that slowing down in rates of recovery after a perturbation may provide advance warning that a critical transition is approaching. Perturbation experiments with microbial populations have supported this hypothesis under controlled laboratory conditions, but evidence from natural ecosystems remains rare. Here, we manipulated rocky intertidal canopy algae to test the hypothesis that the spatial scale at which the system recovers from a perturbation in space should increase as the system approaches the tipping point, marking the transition from a canopy-dominated to a turf-dominated state...

The Southern Hemisphere may have provided biodiversity refugia after the Cretaceous/Palaeogene (K/Pg) mass extinction. However, few extinction and recovery studies have been conducted in the terrestrial realm using well-dated macrofossil sites that span the latest Cretaceous (late Maastrichtian) and early Palaeocene (Danian) outside western interior North America (WINA). Here, we analyse insect-feeding damage on 3,646 fossil leaves from the latest Maastrichtian and three time slices of the Danian in Chubut, Patagonia, Argentina (palaeolatitude approximately 50° S)...

Loss-of-function mutations in SCN1A cause Dravet syndrome (DS), a catastrophic childhood epilepsy in which patients experience comorbid behavioral conditions, including movement disorders, sleep abnormalities, anxiety, and intellectual disability. To study the functional consequences of voltage-gated sodium channel mutations, we use zebrafish with a loss-of-function mutation in scn1lab, a zebrafish homolog of human SCN1A. Homozygous scn1lab(s552/s552) mutants exhibit early-life seizures, metabolic deficits, and early death...

Earthquake-generated tsunamis threaten coastal areas and low-lying islands with sudden flooding. Although human hazards and infrastructure damage have been well documented for tsunamis in recent decades, the effects on wildlife communities rarely have been quantified. We describe a tsunami that hit the world's largest remaining tropical seabird rookery and estimate the effects of sudden flooding on 23 bird species nesting on Pacific islands more than 3,800 km from the epicenter. We used global positioning systems, tide gauge data, and satellite imagery to quantify characteristics of the Tōhoku earthquake-generated tsunami (11 March 2011) and its inundation extent across four Hawaiian Islands...

Grape color somatic variants that can be used to develop new grapevine cultivars occasionally appear associated to deletion events of uncertain origin. To understand the mutational mechanisms generating somatic structural variation in grapevine, we compared the Tempranillo Blanco (TB) white berry somatic variant to its black berry ancestor, Tempranillo Tinto. Whole-genome sequencing (WGS) uncovered a catastrophic genome rearrangement in TB that caused the hemizygous deletion of 313 genes, including the loss of the functional copy for the MYB transcription factors required for anthocyanin pigmentation in the berry skin...

BACKGROUND: Although drug-eluting stents have dramatically reduced the rates of restenosis and target lesion revascularization, they are associated with stent thrombosis (ST), a catastrophic event likely due to delayed endothelialization and chronic inflammation caused by the polymer and the metal scaffolds. To increase the safety and efficacy of stents, polymer-free dual drug-eluting stents (DDES) have been developed. METHODS: A total 160 stents (Bare-metal stents (BMS), polymer-free probucol stents (PrES), sirolimus-eluting stents (SES) and DDES) were randomly implanted in the coronary arteries of 80 pigs...

The aim of the study was to find relevant coping factors for the development of psychological interventions for people with chronic fatigue syndrome who suffer from depressive symptoms. A total of 30 adults with chronic fatigue syndrome filled in the Cognitive Emotion Regulation Questionnaire, the COPE and the Hospital Anxiety and Depression Scale. The findings suggested that cognitive coping strategies have a stronger influence than behavioral coping strategies on depressive symptoms. Especially, the cognitive coping strategies refocusing positive, positive reappraisal and catastrophizing were of importance...

The purpose of this study was to evaluate the psychometric properties of the Spanish version of the Fear of Pain Questionnaire-III. The original three-factor structure of the Fear of Pain Questionnaire-III was confirmed and indicated a good to excellent level of internal consistency. Criterion validity was supported by positive significant correlations between the Fear of Pain Questionnaire-III scores and measures of pain catastrophizing and anxiety sensitivity; discriminant validity was supported by non-significant correlations between the Fear of Pain Questionnaire-III scores and measures of pain intensity and depressive symptomatology...

Hyponatremia is the most common electrolyte abnormality seen in hospitalized patients, with up to 30 % having a plasma sodium concentration below 135 mmol/l. It is now clear that the clinical problem extends beyond the neurological symptoms, which can be explained by intracerebral osmotic fluid shifts and brain edema. Instead, chronic hyponatremia is associated with impaired gait stability and an increased risk of bone fragility fractures. Moreover, hyponatremia has been demonstrated to be an indicator of poor prognosis in a variety of conditions...

The Great Dismal Swamp (GDS) National Wildlife Refuge delivers multiple ecosystem services, including air quality and human health via fire mitigation. Our analysis estimates benefits of this service through its potential to reduce catastrophic wildfire related impacts on the health of nearby human populations. We used a combination of high-frequency satellite data, ground sensors, and air quality indices to determine periods of public exposure to dense emissions from a wildfire within the GDS. We examined emergency department (ED) visitation in seven Virginia counties during these periods, applied measures of cumulative Relative Risk to derive the effects of wildfire smoke exposure on ED visitation rates, and estimated economic losses using regional Cost of Illness values established within the US Environmental Protection Agency BenMAP framework...

The 2014 Ebola virus disease (EVD) outbreak affected several countries worldwide, including six West African countries. It was the largest Ebola epidemic in the history and the first to affect multiple countries simultaneously. Significant national and international delay in response to the epidemic resulted in 28,652 cases and 11,325 deaths. The aim of this study was to develop a risk analysis framework to prioritize rapid response for situations of high risk. Based on findings from the literature, sociodemographic features of the affected countries, and documented epidemic data, a risk scoring framework using 18 criteria was developed...

We report a 72-year-old man who underwent fixation with a multifilament cerclage system after a peri-prosthetic trochanteric fracture (Vancouver A1). Failure of cerclage occurred after 23 month and revision of trochanteric attachment was performed due to non-union. Intraoperatively fragments of the cable were found between prosthesis head and liner. Cup and head were changed and the greater trochanter was re-attached after allograft-impaction. Based on the present case report multifilament cerclage cables should be used with precaution and might require a close and frequent follow-up given the possibility of cerclage breakage and consecutive catastrophic wear by migration of cerclage particles...
