We report a case of anti-protein death 1-induced sarcoid-like reaction in a 63-year-old Caucasian male who was diagnosed with stage IV-M1a melanoma. He was initially treated with pembrolizumab monotherapy (Q3W) and had a complete response after 14 cycles. However, relapse was suspected 3 months later with appearance of hilar, mediastinal and hepatic hilar lymph nodes as well as a skin lesion. Biopsy of both the hilar lymph nodes and the skin lesion demonstrated sarcomatoid granulomatosis. Pembrolizumab was discontinued temporarily. While on F-FDG-PET/CT, all sarcoid-like lesions regressed in size and activity, a new hypermetabolic solitary skeletal lesion was detected in a lumbar vertebra, suspicious for metastasis. However, since the patient was asymptomatic, a watchful-waiting attitude was taken. During this period, a spontaneous and complete resolution of the metabolic activity was observed of the skeletal lesion. Until today, the patient remains in complete remission. Current case presents an atypical presentation and evolution of anti-PD-1-induced sarcoid-like reaction, illustrating the difficulty of differentiating it from disease progression. Before considering (re-)initiation of anti-melanoma therapy, a tissue biopsy of one of the suspected lesions may be performed to confirm diagnosis. Physicians treating patients with ICI should be aware of this difficulty and critically assess the nature of lesions suspect of progression in patients responding to ICI and presenting with a sarcoid-like reaction.In order to assess the extent of agreement between forensic footwear examiners in the United States, a reliability study was performed by West Virginia University between February 2017 and August 2018. Over the span of 19 months, 70 examiners each performed 12 comparisons and reported a total of 840 conclusions. For each comparison, participants were queried on a number of factors in order to determine the degree to which different types of features were identified, evaluated, and weighted, before arriving at a final decision regarding the strength of the association or disassociation between questioned and test impressions. Preliminary results from this study are divided into a series of three summaries. This manuscript (Part I) describes participant demographics as well as community agreement in both feature identification/annotation, and final reporting. Results indicate considerable variation in feature identification/annotation (as low as 66.5% agreement), but higher consistency in the reporting of overall conclusions. For mated pairs, this agreement was 79.7% ± 14.1% (median of 85.7% and a 90% confidence interval between 75.9% and 83.2%). For nonmated pairs, the equivalent overall agreement was 89.8% ± 6.69% (median of 91.4% and a 90% confidence interval between 87.4% and 92.1%). These estimates of agreement are further compared with previous published findings, and collectively, the work extends the body of knowledge concerning reliability in forensic footwear comparisons and conclusions.
  Smartphone addiction is a growing social problem with adverse health outcomes. There are few comparative studies in Asia that examine factors associated with smartphone addiction. The current study aimed to address this research gap by presenting a comparative analysis of factors associated with smartphone addiction in Japan and Thailand, two countries heterogeneous in both their level of economic development and culture.
 
  Participant data were collected using two population-based surveys. Participants were high school students in grade 11, aged 16-17 years old, and were selected using quota sampling in Japan in 2014 and random sampling in Thailand in 2016. The outcome of interest was smartphone addiction, measured using a modified version of the Young Diagnostic Questionnaire for Internet Addiction. Multiple logistic regression analysis was performed to determine factors associated with smartphone addiction (gender; nationality; family connectedness; and average time spent on smartphone per day).
 
  This srotective effect of parental connectedness.
 Smartphone addiction was more prevalent among Thai adolescents than Japanese adolescents, and more prevalent among females than males in both countries. Interventions for reducing smartphone addiction should take into account both context and gender, and should leverage the protective effect of parental connectedness.
  The aim of the present work was to investigate family clusters of Shiga toxin-producing Escherichia coli (STEC) infection among the household members of STEC positive patients, identified within a screening program of bloody diarrhea (BD) for STEC in Northern Italy.
 
  Stool samples from patients with BD or BD-associated-hemolytic uremic syndrome (HUS) and related households were investigated by molecular and bacteriologic methods to detect and characterize the virulence profile of STEC and Pulsed Field Gel Electrophoresis analysis were done on isolates.
 
  Thirty-nine cases of STEC infection (isolated BD in 16, BD-associated-HUS in 23) were considered, and a total of 130 stool samples from 1 to 8 households of the index patient were analyzed. The prevalence of positivity was higher in siblings (34.8%, 8/23) than in mothers (20%, 7/35), grandparents (9.5%, 2/21), fathers (8.8%, 3/34) or other households.  https://www.selleckchem.com/products/VX-770.html  In 14 clusters (36%), one or more household shared a STEC with the same virulence profile (stx, eae, serogroup) as the index case. In 7 clusters, STEC strains isolated from at least 2 subjects also shared identical Pulsed Field Gel Electrophoresis profile. The frequency of household infection does not appear to be associated to the index case's illness (HUS or BD), nor with the serotype or with the virulence profile of the involved STEC (stx2 or stx1-stx2).
 
  Our study shows that STEC infections, most likely related to human-to-human transmission, are common among households of patients with STEC BD or HUS and underlines the importance of extending the epidemiologic investigations to all family members, as the index case may not always be the primary infection in the family.
