BACKGROUND: Gout is a purine metabolism disease. Tophaceous gout may cause joint destruction and other systemic problems and sometimes may be complicated by infection. Infection and sinus with discharge associated with tophaceous gout are serious complications, and treatment is difficult. We present a patient with tophaceous gout complicated by infection and discharging sinus treated by bilateral amputation at the level of the first metatarsus. METHODS: A 43-year-old man previously diagnosed as having gout, and noncompliant with treatment, presented with tophaceous gout associated with discharging sinus and infection on his left first metatarsophalangeal joint...

A 70-year-old man visited our emergency department, whose laboratory test results revealed leucocytosis, anaemia, thrombocytopenia and high levels of serum lactate dehydrogenase. In addition, the peripheral blood smear revealed neutrophilic granulocytes with nuclear hypolobation (pseudo-Pelger-Hüet anomaly), hypogranulation and no myeloperoxidase reactivity. Genetic testing of the peripheral blood sample was as follows: G-band, 46XY,t(9;22)(q34;q11.2) (20/20); fluorescence in situ hybridisation BCR/ABL fusion signal, 97%; and analysis of exons 5-9 of the p53 gene, mutation (Pro72Arg) in exon 4 protein...

There has been a growing interest in recent years in the assessment of suitable vial/stopper combinations for storage and shipment of frozen drug products. Considering that the glass transition temperature (Tg) of butyl rubber stoppers used in Container Closure Systems (CCS) is between -55°C to -65°C, a storage or shipment temperature of a frozen product below the Tg of the rubber stopper, may require special attention, since below the Tg the rubber becomes more plastic-like and loses its elastic (sealing) characteristics...

Acquired traumatic brain injury (TBI) is frequently accompanied by persistent cognitive symptoms, including executive function disruptions and memory deficits. The Morris Water Maze (MWM) is the most widely-employed laboratory behavioral test for assessing cognitive deficits in rodents after experimental TBI. Numerous protocols exist for performing the test, which has shown great robustness in detecting learning and memory deficits in rodents after infliction of TBI. We review applications of the MWM for the study of cognitive deficits following TBI in pre-clinical studies, describing multiple ways in which the test can be employed to examine specific aspects of learning and memory...

Fatigue is a common complaint in older people. Laboratory-induced muscle fatigue has been found to affect physical functions in older populations but these protocols are rigorous and are unlikely to accurately reflect daily activities. This study used an ecological approach to determine the effects of a busy day on self-reported fatigue and fall-related measures of physical and cognitive function in older people. Fifty community-dwelling adult volunteers, aged 60-88 (mean 73) years participated in this randomised crossover trial...

OBJECTIVE: This was a first cross-sectional single-center study to research the relation between globus pharyngeus, OSA and GERD. Since previous clinical studies have demonstrated a relationship between globus phayrngeus and GERD, however, no reported study on the relation between globus pharyngeus, sleep disorders including OSA, and GERD. METHODS: Seventeen patients underwent general and otorhinolaryngological examinations and responded to several questionnaires (ESS, PSQI, HADS, and Globus pharyngeus VAS score) at their first visit, and underwent a gastroesophageal test for 24-h pH monitoring and in-laboratory PSG one to two months later...

BACKGROUND: Although pulmonary artery banding (PAB) is a common palliative procedure for pediatric heart malformation, there are concerns of pressure overload and concomitant immune reactions in the right ventricle causing postsurgical complications such as pericardial effusion. At this time, no clear guidelines as to potential risk factors or procedural contraindications have been widely disseminated. Therefore, a study was undertaken to examine wide-ranging factors to find potential biomarkers for postsurgical pericardial effusion formation risk...

Sedentary behavior (SB) has detrimental consequences and cannot be compensated for through moderate-to-vigorous physical activity (PA). In order to understand and mitigate SB, tools for measuring and monitoring SB are essential. While current direct-to-customer wearables focus on PA, the VitaBit validated in this study was developed to focus on SB. It was tested in a laboratory and in a free-living condition, comparing it to direct observation and to a current best-practice device, the ActiGraph, on a minute-by-minute basis...

This work presents the design, construction and testing of a new embedded sensor system for monitoring concrete curing. A specific mote has been implemented to withstand the aggressive environment without affecting the measured variables. The system also includes a real-time monitoring application operating from a remote computer placed in a central location. The testing was done in two phases: the first in the laboratory, to validate the functional requirements of the developed devices; and the second on civil works to evaluate the functional features of the devices, such as range, robustness and flexibility...

Multidrug-resistant (MDR) and extensively-drug-resistant (XDR) Gram-negative bacteria have emerged as a major threat to human health globally. This has resulted in the "re-discovery" of some older antimicrobials and development of new agents, however resistance has also rapidly emerged to these agents. Areas Covered: Here we describe recent developments in resistance to three of the most important last-line antimicrobials for treatment of MDR and XDR Gram negatives: fosfomycin, colistin and ceftazidime-avibactam...

PURPOSE: to identify the role of laser scanning confocal microscopy (LSCM) in diagnostic and to assess the effectiveness of involutional blepharitis treatment. MATERIAL AND METHODS: The study involved 32 patients (64 eyes) with chronic blepharitis aged in average 75.21±3.56 years. All patients completed questionnaire (SPEED), underwent Schirmer I, Norn tear break-up time and compression tests, had the number of functioning meibomian glands (NFMG) calculated. The patients' eyelids were examined with LSCM, and the condition of conjunctiva was evaluated by microbiological study...

BACKGROUND: Severe fever with thrombocytopenia syndrome (SFTS) is a life-threatening infectious disease identified in 2009. SFTS is mainly transmitted by contact with ticks or animals; however, sporadic reports suggested that SFTS could be transmitted among humans. OBJECTIVES: We aimed to comprehensively characterize clinical features and disease progression of SFTS acquired by human-to-human transmission. STUDY DESIGN: A retrospective study of 90 SFTS patients was performed in a tertiary hospital of Nanjing, China, from October 2010 to October 2016...

Different remediation techniques have been used to restore metal-contaminated sites, including stabilizing metals by adding amendments to the soils. This study experimented three biochars, made from wood and miscanthus, cultivated on contaminated and uncontaminated soils, used as amendments at a 2% application rate on a metal-contaminated soil for 9 months in laboratory-controlled conditions. The objective was to evaluate whether biochars were able to decrease the availability and human oral bioaccessibility of metals in an alkaline soil...

The usage of wastes of algae would be admirable from environmental and solid waste management point of view. Thus, herein, this data set present a facile method for providing an adsorbent from mixture of algae waste-bentonite. The prepared adsorbent was applied to remove Pb2+ from aqueous solution. The characterization data of the adsorbent were analyzed using FTIR and SEM-EDX methods. The FTIR test results showed that there is a shift in the wave numbers on the adsorbent that has been loaded with Pb indicating that there is an interaction between the adsorbent and Pb...

This article contains information related to a recent study "Performance-based interpretation of in-plane cyclic tests on RC frames with strong masonry infills" (Morandi et al., 2017 [1]). Motivated by the necessity to improve the knowledge of the in-plane seismic response of rigid strong masonry infills, a wide experimental campaign based on in-plane cyclic tests on full-scale RC infilled frame specimens, supplemented with a complete characterization of the materials, has been conducted at the laboratory of the Department of Civil Engineering and Architecture of the University of Pavia...
