A trigger digit is relatively uncommon in adolescents and often has a different etiology in that age group vs adults. In the pediatric population, trigger digits frequently arise from a variety of underlying anatomic situations, including thickening of the flexor digitorum superficialis or flexor digitorum profundus tendons, an abnormal relationship between the flexor digitorum superficialis and flexor digitorum profundus tendons, a proximal flexor digitorum superficialis decussation, or constriction of the pulleys...

BACKGROUND: Prostate cancer (PCa) is not commonly found in men younger than 50 years of age. However, serum prostate-specific antigen (PSA) concentration has been examined more frequently at a younger age in Asia partially due to an increased awareness of prostate cancer. The purpose of our study was to investigate the efficacy and complication of PSA-triggered transrectal ultrasonography-guided prostate (TRUSP) biopsies. We retrospectively reviewed TRUSP biopsies in young men with elevated PSA concentration in Taipei Veterans General Hospital...

Ochratoxin A (OTA) is one of the most common and dangerous mycotoxins in the world. Previous work indicated that OTA could elicit spontaneous HR-like lesions formation Arabidopsis thaliana, reactive oxygen species (ROS) play an important role in OTA toxicity, and their major endogenous source is mitochondria. However, there has been no evidence as to whether OTA induces directly PCD in plants until now. In this study, the presence of OTA in Arabidopsisthaliana leaves triggered accelerated respiration, increased production of mitochondrial ROS, the opening of ROS-dependent mitochondrial permeability transition pores and a decrease in mitochondrial membrane potential as well as the release of cytochrome c into the cytosol...

Trigger finger is a mechanical problem with many etiological factors as possible causes, such as diabetes mellitus, carpal tunnel syndrome and repetitive finger movements. Although it can afflict anyone, it is much commoner in middle-aged women than men and the most commonly involved digit is reported to be the thumb. The diagnosis is mainly based on clinical symptoms during examination and first-line treatment is conservative with splinting and corticosteroid injections. Surgical open release is the "gold standard" of trigger finger treatment because it allows more careful inspection of the surgical area and is highly effective with low complication rates...

BACKGROUND: The purpose of this study was to identify predictive factors of poor response to intra-flexoral sheath corticosteroid injection, as well as to identify factors associated with patients' decisions to undergo surgical treatment. METHODS: Data from 112 patients who received steroid injection treatment for trigger finger were reviewed retrospectively. Logistic regression was used to assess the prognostic value of factors assumed to affect prognosis (age, sex, underlying disease, history of illness, presence of carpal tunnel syndrome, multiple digit involvement, and pre- and post-operative disability scores)...

OBJECTIVES: Apical periodontitis can appear clinically as apical granulomas or radicular cysts. There is evidence that immunologic factors are involved in the pathogenesis of both pathologies. In contrast to radicular cysts, the dentigerous cysts have a developmental origin. Macrophage polarization (M1 vs M2) is a main regulator of tissue homeostasis and differentiation. There are no studies comparing macrophage polarization in apical granulomas, radicular cysts, and dentigerous cysts...

The aim of this systematic review was to develop an evidence-based guideline to assist clinicians in the treatment of adult trigger digits. There is moderate evidence to suggest that local corticosteroid injection is a safe and effective short-term treatment and it may, therefore, be recommended as an initial treatment for this condition. However, when compared with surgery, there is strong evidence that corticosteroid injection is associated with increased rates of ongoing or recurrent symptoms at 6 months after intervention...

Protected areas (PAs) are the main instrument for biodiversity conservation, which has triggered the development of numerous indicators and assessments on their coverage, performance and efficiency. The connectivity of the PA networks at a global scale has however been much less explored; previous studies have either focused on particular regions of the world or have only considered some types of PAs. Here we present, and globally assess, ProtConn, an indicator of PA connectivity that (i) quantifies the percentage of a study region covered by protected connected lands, (ii) can be partitioned in several components depicting different categories of land (unprotected, protected or transboundary) through which movement between protected locations may occur, (iii) is easy to communicate, to compare with PA coverage and to use in the assessment of global targets for PA systems...

Human herpesviruses 6A/B (HHV-6A/B) can integrate their viral genomes in the telomeres of human chromosomes. The viral and cellular factors contributing to HHV-6A/B integration remain largely unknown, mostly due to the lack of efficient and reproducible cell culture models to study HHV-6A/B integration. In this study, we characterized the HHV-6A/B integration efficiencies in several human cell lines using two different approaches. First, after a short-term infection (5h) cells were processed to single-cell cloning and analyzed for chromosomally-integrated HHV-6A/B (ciHHV-6A/B)...

The main complaints in extensor tendon dislocations are pain, swelling, sense of discomfort, snapping and difficulty in writing and forceful flexion. However, congenital extensor tendon subluxations may present with triggering of the fingers due to tendon dislocations. Unnecessary A1 pulley release may be performed for pseudotriggerring with unsuccessful results. Here, we report an unusual case of congenital extensor tendon subluxation of multiple digits with triggering of the left little finger and aim to attract notice to pseudotriggering of the digits due to tendon dislocations...

In this "digital age," the model of healthcare is changing rapidly, primarily in the area of communication that is happening among the major stakeholders each minute. Patients, being the central point of the importance of all the work and development, are more empowered than ever with information from various sources, among which social media is leading from the front. This article reviews how social media engages healthcare service providers, service seekers, and regulatory authorities. If the gaps in the current regulations are filled, better healthcare outputs can be triggered...

BACKGROUND: Stenosing tenosynovitis, or trigger digit, is a common condition for which patients often seek relief. Corticosteroid injections have been shown to provide relief in many cases, and several different approaches for delivering the injection have been described in the literature. We compared patients' perception of pain following each of 3 accepted injection methods, namely, palmar proximal, palmar distal, and webspace approaches. METHODS: We prospectively followed 38 patients with 39 symptomatic digits in this trial, with varying severities of trigger finger as graded by the Patel and Moradia classification...

Voyer and colleagues (2016) report an interesting and important comparison of ten attention/concentration tests for DSM-5 delirium. I have a number of questions and comments as follows: (1) What training did the research assistants have? DSM-5 diagnosis is generally regarded as a decision by medical specialists. When the person has prior dementia, identifying delirium is a high-level medical skill. Behavioral and psychological symptoms of dementia can closely mimic delirium unless the examiner focuses on behavioral triggers and the speed of cognitive decline...

Recently developed information communication technologies, particularly the Internet, have affected how we, both as individuals and as a society, create, store, and recall information. The Internet also provides us with a great opportunity to study memory using transactional large-scale data in a quantitative framework similar to the practice in natural sciences. We make use of online data by analyzing viewership statistics of Wikipedia articles on aircraft crashes. We study the relation between recent events and past events and particularly focus on understanding memory-triggering patterns...

<p>Dyschromia is one of the primary complaints for patients with skin of color. Treatments need to achieve a balance between tolerability and efficacy to address existing hyperpigmentation without causing additional damage that could trigger post-inflammatory hyperpigmentation (PIH). An open-label, single-center study was conducted to assess the efficacy of a novel comprehensive pigmentation control serum (LYT2) combined with a series of three very superficial chemical peels (VP) in skin of color subjects...

The output bandwidth and the capability to generate multiple analog outputs with accurately adjustable relative phase are important specifications of arbitrary waveform generator (AWG). To increase the output bandwidth, AWG with a multi-memory paralleled direct digital synthesizer structure (DDS) was proposed to break through operating speed limitations of memory and field programmable gate array. But this structure does complicate synchronization of the analog outputs. This paper proposes a structure for synchronization of the outputs of multi-channel high speed AWG that generates arbitrary waveforms using a multi-memory paralleled DDS...

Objectives: Horizontal gene transfer of antimicrobial resistance (AMR) genes between clinical isolates via transduction is poorly understood. MRSA are opportunistic pathogens resistant to all classes of antimicrobial agents but currently no strains are fully drug resistant. AMR gene transfer between Staphylococcus aureus isolates is predominantly due to generalized transduction via endogenous bacteriophage, and recent studies have suggested transfer is elevated during host colonization...

Stimulus-triggered averaging (StTA) of forelimb muscle electromyographic (EMG) activity was used to investigate individual forelimb muscle representation within the primary motor cortex (M1) of rhesus macaques with the objective of determining the extent of intra-areal somatopic organization. Two monkeys were trained to perform a reach-to-grasp task requiring multi-joint coordination of the forelimb. EMG activity was simultaneously recorded from 24 forelimb muscles including 5 shoulder, 7 elbow, 5 wrist, 5 digit, and 2 intrinsic hand muscles...
