RESUMEN
INTRODUCTION: Anaplastic large-cell lymphoma (ALCL) rarely occurs in the central nervous system in the pediatric population. CASE PRESENTATION: We describe a diagnostically challenging case of an 11-month-old infant presenting with cranial nerve palsies and peripheral eosinophilia. Imaging demonstrated meningeal thickening with enhancement and dura-based deposits, the biopsy of which revealed features of ALK-1 negative ALCL on histologic and immunophenotypic analysis. A thorough investigation excluded the possibility of any extra-cranial origin. Hence, a diagnosis of "primary" ALCL was rendered. CONCLUSION: ALCL arising in the dura in an infant has not been described earlier, to the best of our knowledge.

Pulmonary blastoma (PB) is an exceedingly rare and aggressive malignant lung neoplasm that has distinct biphasic morphology. In this report, we document rare manifestations and molecular alterations in PB. A 59-year-old non-smoker female, presented with cough and hemoptysis for 4 months. The high-resolution computed tomography chest scan showed a 3.5x2.7 cm mass in the basal segment of the left lung. Positron emission tomography and computed tomography revealed a fluorodeoxyglucose avid lobulated mass in the superior segment of the lower lobe of the left lung. On core biopsy, the diagnosis of pleomorphic carcinoma in a background of adenocarcinoma was made. A definite diagnosis of pulmonary blastoma was established on the left lung lobectomy specimen based on morphological and immunohistochemical findings. Post-surgical biopsy from the scalp swelling showed metastatic deposits. On Next Generation Sequencing (NGS), in addition to conventional CTNNB1 gene mutation, new pathogenic MYCN and ATM gene mutations were detected. Post-chemotherapy, the patient was doing well after 10 months of close follow-up. PB exhibited rare associations in the form of non-smoker status, scalp metastasis, and MYCN and ATM gene mutations on NGS in addition to conventional CTNNB1 gene mutation. Large cohort studies are required to discover the incidence, significance and therapeutic implications of these co-existing pathogenic molecular alterations in PB.

The latest buzzword in today's world is fake news. The circulation of false information influences elections, public health, brand reputations, and violence. Hence, the severity of the threat of fake news is increasing. The danger for fake news exists everywhere globally and is not specific to one language or nation. The creators of fake news layer the facts in the news with misinformation to confuse the readers. Hence, a need arises for creating a model for detecting fake news in multiple languages. This paper proposes a unified attention-based model Mul-FaD to detect fake news in various languages. We have created our dataset with around 40000 articles in English, German, and French. This paper also shows an exploratory analysis of the dataset created. In this paper, we perform experiments from a multilingual perspective in which we use an altered hierarchical attention-based network to detect fake news. Our model is able to achieve an accuracy of 93.73 and an F1 score of 92.9 for the combined corpus of the three languages.
RESUMEN
CONTEXT.: Laboratories of many medical college hospitals in India do not offer important diagnostic tests, most of which are routine in the West. This detracts from the service as well as the educational function of the college. OBJECTIVES.: To provide the background to pathology and laboratory medicine services and education in India, and to create a questionnaire that will put the lack of tertiary care laboratory services in perspective. This article will help illustrate the lacunae in laboratory medicine services and in the education of students. For this, we present information on the health services and pathology education facilities in India. We propose a questionnaire comprising 30 questions in various disciplines in pathology and laboratory medicine. These questions will help administrators and bureaucrats evaluate the status of the laboratories with respect to the services provided. DATA SOURCES.: Sources include Web sites of the government of India, including that of the National Accreditation Board for Testing and Calibration Laboratories; indexed medical journal articles; and standard books and white papers on health care in India. We also used our personal experiences and interpretations of the laboratory and medical education sector in India. CONCLUSIONS.: Medical colleges in India need to offer specialized diagnostic services if they are to achieve the targets of universal health care as well as turning out competent doctors. The agencies responsible for health care in India should use the questionnaire as a first step toward improving laboratory services. Other low- and middle-income countries should also adopt this method.

Juvenile granulosa cell tumor (JGCT) of the ovary is an uncommon malignancy, with most cases seen in adolescent girls and young women. The majority of these patients present with unilateral ovarian disease, and to date, bilateral JGCTs have been reported in 10 cases. Although the histopathologic features have been detailed in the published literature, extensive extracellular mucin deposition has been documented in only one case. Herein, we report a 17-year-old adolescent girl with bilateral solid-cystic adnexal masses diagnosed as bilateral JGCT with abundant extracellular mucin deposition on histopathology. The index case highlights a rare clinical and histopathologic presentation of JGCT. Adequate knowledge of such unusual presentations is essential for accurate distinction from other ovarian tumors and appropriate management.

Autoimmune hepatitis (AIH) is a chronic and progressive disease of the liver. This is a multifactorial autoimmune disease with both environmental factors and genetic factors playing a role in its pathogenesis. Certain environmental agents like viruses, drugs, etc., can trigger the disease in a genetically susceptible individual. The present study was aimed to explore the distribution of human leukocyte antigen (HLA)-DRB1, Protein tyrosine phosphatase non-receptor type 22 (PTPN22) and Cytotoxic T-Lymphocyte-associated protein 4 (CTLA-4) polymorphisms in North Indian adult AIH patients and their associations with clinical and pathological characteristics associated with the disease. A total of 147 subjects with 47 cases and 100 healthy controls were enrolled. Diagnosis of AIH was made by Revised International Autoimmune Hepatitis Group scoring system. HLA-DRB1 Typing was done by Luminex-based reverse Sequence-Specific Oligonucleotide Probing (SSOP). Single nucleotide variant (SNV) genotyping for CTLA-4 and PTPN22 was done by simple probe-based SNP arrays. Results indicated SLA positive AIH patients are poor responders to therapy. A significant predispositional association of HLA-DRB1*03 was observed in AIH patients from the North Indian population (p= 0.0001, OR=4.83 (2.30-10.15). The frequency of the GG genotype of CTLA-4 CT 60 was significantly increased in AIH patients compared to controls. Multinomial analysis showed that CTLA-4 CT 60 is an independent predictor for cases.

Police abuse affects people who inject drugs (PWID), including those with HIV, and negatively impacts care engagement. This cross-sectional study evaluated police abuse among PWID receiving MOUD (medication for opioid use disorder) living with HIV and associations with HIV treatment adherence and receipt of NGO services. We assessed lifetime and past six-month rates of police abuse among a cohort of Ukrainian PWID with HIV receiving MOUD (n = 190) from August to September 2017. Logistic regression models evaluated associations between past six-month police abuse and past 30-day antiretroviral therapy (ART) adherence, and past six-month NGO service receipt. Almost all (90%) participants reported lifetime police abuse: 77% reported physical violence and 75% reported paying the police to avoid arrest. One in four females (25%) reported police-perpetrated sexual violence. Recent police abuse was reported by 16% of males and 2% of females and was not associated with ART adherence (aOR: 1.1; 95% CI:0.3-5.0) or NGO service receipt (aOR: 3.4; 95% CI:0.6-18.3). While lifetime police abuse rates were high, few participants reported recent police abuse, which was not linked to care engagement. These trends should encourage the Ukrainian government for public health-public safety partnerships and legal interventions to eliminate human rights violations against PWID living with HIV.

Dabigatran, a novel oral anticoagulant, is a direct thrombin inhibitor and is being increasingly used owing to the advantage of dosing without the need for laboratory monitoring. While extensive skin necrosis is known to be associated with oral anticoagulants such as warfarin and factor Xa inhibitors, dabigatran toxicity typically manifests with bleeding, especially in the elderly. We describe a 70-year-old woman who was prescribed dabigatran for the treatment of unprovoked deep venous thrombosis. She developed bleeding diathesis along with extensive skin necrosis and acute kidney injury shortly after commencing the drug. Haemodialysis was given in view of dabigatran toxicity and complications of kidney dysfunction which resolved promptly over a week. However, the patient succumbed to severe sepsis from secondary skin infections. It is crucial to closely monitor for signs of dabigatran toxicity, especially in the elderly patients.

This retrospective study examines demographic and risk factor differences between children who visited the emergency department (ED) for asthma once ("one-time") and more than once ("repeat") over an 18-month period at an academic medical center. The purpose is to contribute to the literature on ED utilization for asthma and provide a foundation for future primary research on self-management effectiveness (SME) of childhood asthma. For the first round of analysis, an 18-month retrospective chart review was conducted on 252 children (0-17 years) who visited the ED for asthma in 2019-2020, to obtain data on demographics, risk factors, and ED visits for each child. Of these, 160 (63%) were "one-time" and 92 (37%) were "repeat" ED patients. Demographic and risk factor differences between "one-time" and "repeat" ED patients were assessed using contingency table and logistic regression analyses. A second round of analysis was conducted on patients in the age-group 8-17 years to match another retrospective asthma study recently completed in the outpatient clinics at the same (study) institution. The first-round analysis indicated that except age, none of the individual demographic or risk factors were statistically significant in predicting of "repeat" ED visits. More unequivocally, the second-round analysis revealed that none of the individual factors examined (including age, race, gender, insurance, and asthma severity, among others) were statistically significant in predicting "repeat" ED visits for childhood asthma. A key implication of the results therefore is that something other than the factors examined is driving "repeat" ED visits in children with asthma. In addition to contributing to the ED utilization literature, the results serve to corroborate findings from the recent outpatient study and bolster the impetus for future primary research on SME of childhood asthma.

Young Asian American women have high rates of depression and suicidality; however, few interventions address the urgent need for culturally informed care. Asian Women's Action for Resilience and Empowerment (AWARE) aims to be the first gender and culturally specific group psychotherapy intervention designed to improve mental and sexual health in Asian American women with trauma. This article specifically focuses on identifying the mechanisms of action that were responsible for improving mental health and well-being among those who participated in AWARE randomized controlled trial. Of the 435 women screened for the study, 63 Chinese, Korean, and Vietnamese women with histories of interpersonal violence were randomized into either the intervention (n = 32) or waitlist control groups (n = 31). Data from 16 posttrial focus group sessions were then thematically analyzed to explore the key themes and mechanisms of action of the AWARE intervention. Analysis revealed four cultural mechanisms that facilitated mental health improvements: psychoeducation on disempowering parenting, the reduction of mental illness-related stigma, community and relational building, and a heightened sense of empowerment. Results suggest that the AWARE intervention fosters Asian American women's well-being on an individual level and encourages social engagement through culturally salient messages. Women in the study were able to expand their social support network, engage in activism, and develop an empowered connection to their community.
