Mixed tumors are uncommonly observed in the musculoskeletal system, where they form a common spectrum with a myoepithelioma and a parachordoma. Herein, we present a rare case of a mixed tumor/myoepithelioma arising in the iliac bone of a young adult male who presented with swelling in his right hip. Radiological imaging disclosed a large, intraosseous, lytic, heterogenous mass with a soft tissue component. Biopsy and subsequent tumor resection showed an 18 cm sized tumor involving the iliac bone and soft tissues and comprising polygonal and spindly cells, arranged in cords and aggregates, embedded in a myxohyaline stroma with osteochondroid differentiation. Tumor cells exhibited mild nuclear variation, rare mitotic figures, focal cytoplasmic clearing, and prominent squamous differentiation. On immunohistochemistry (IHC), tumor cells were diffusely positive for S100-P, EMA, CK5/6, p63, GFAP, calponin, and focally positive for CK/MNF116, but negative for Brachyury/T. Diagnosis of a myoepithelioma/mixed tumor was offered. Further, cytogenetic analysis revealed lack of EWSR1 gene rearrangement and showed clonal trisomies of 11, 15, 17 with del (16q) and del (22q11). The present case is a rare documentation of a myoepithelioma in the appendicular bones and the second such case identified in the iliac bone. IHC and cytogenetic findings supported a myoepithelial cell origin, and reinforced its relationship with a parachordoma and its distinction from mixed salivary gland tumors, a chordoma, and an extraskeletal myxoid chondrosarcoma that form its differential diagnoses. 相似文献

Since May 2022, an international monkeypox (MPX) outbreak has been ongoing in more than 50 countries. While most cases are men who have sex with men, transmission is not restricted to this population. In this report, we describe the case of a male child younger than 10 years with MPX in the Netherlands. Despite thorough source tracing, a likely source of infection has not been identified. No secondary cases were identified in close contacts. 相似文献

Introduction
Implementation of patient-centred care (PCC) practices in HIV treatment depends on healthcare workers’ (HCWs) perceptions of the acceptability, appropriateness and feasibility of such practices (e.g. use of intentional, metric-driven activities to improve patient experiences).Methods
We applied rapid, rigorous formative research methods to refine a PCC intervention for future trial. In 2018, we conducted focus group discussions (FGDs) with 46 HCWs purposefully selected from two pilot sites. We elicited HCW perceptions of HIV service delivery, HCW motivation and perceived value of patient experience measures intended to improve PCC. FGDs utilized participatory methods to understand HCW responses to patient-reported care engagement challenges and Scholl's PCC Framework principles (e.g. seeing a patient as a unique person), enablers (e.g. care coordination) and activities (e.g. patient involvement). Our rapid analysis used analytic memos, thematic analysis, research team debriefs and HCW feedback to inform time-sensitive trial implementation.Results
While HCWs nearly universally identified with and supported principles of PCC in both facilities, they raised practical barriers given the practice environment. HCWs described motivation to help patients, attached value to seeing positive health outcomes and the importance of teamwork. However, HCWs reported challenges with enablers needed to deliver PCC. HCWs cited a work culture characterized by differential power dynamics between cadres and departments restricting HCW autonomy and resource access. Barriers included inflexibility in accommodating individual patient needs due to high patient volumes, limited human resources, laboratory capacity, infrastructure and skills translating patient perspectives into practice. HCW motivation was negatively influenced by encounters with “difficult patients,” and feeling “unappreciated” by management, resulting in cognitive dissonance between HCW beliefs and behaviours. However, the enactment of PCC values also occurred. Results suggested that PCC interventions should reduce practice barriers, highlighting the value of mentors who could help HCWs dynamically engage with health system constraints, to facilitate PCC.Conclusions
While HCWs perceived PCC principles as acceptable, they did not think it universally appropriate or feasible given the practice environment. Participatory and rapid methods provided timely insight that PCC interventions must provide clear and effective systems enabling PCC activities by measuring and mitigating relational and organizational constraints amenable to change such as inter-cadre coordination. 相似文献785.

Introduction
Poor client−provider communication is a critical barrier to long-term retention in care among people living with HIV. However, standardized assessments of this key metric are limited in Africa. We used the Roter Interaction Analysis System (RIAS) to quantitatively characterize patterns of person-centred communication (PCC) behaviours in Zambia.Methods
We enrolled pairs of people living with HIV making routine HIV follow-up visit and their providers at 24 Ministry of Health-facilities supported by the Centre for Infectious Disease Research in Zambia in Lusaka province between August 2019 and November 2021. Client−provider encounters were audio-recorded and coded using RIAS by trained research staff. We performed latent class analysis to identify interactions with distinctive patterns of provider PCC behaviours (i.e. rapport building, person-centred counselling, PCC micropractices [e.g. brief empathy statements], assessing barriers to care, shared decision-making and leveraging discretionary power) and compared their distribution across client, provider, interaction and facility characteristics.Results
We enrolled 478 people living with HIV and 139 providers (14% nurses, 73.6% clinical officers, 12.3% were medical officers). We identified four distinct profiles: (1) “Medically Oriented Interaction, Minimal PCC Behaviours” (47.6% of interactions) was characterized by medical discussion, minimal psychosocial/non-medical talk and low use of PCC behaviours; (2) “Balanced Medical/Non-medical Interaction, Low PCC Behaviours” (21.0%) was characterized by medical and non-medical discussion but limited use of other PCC behaviours; (3) “Medically Oriented Interaction, Good PCC Behaviours” (23.9%) was characterized by medically oriented discussion, more information-giving and increased use of PCC behaviours; and (4) “Highly person-centred Interaction” (7.5%) was characterized by both balanced medical/non-medical focus and the highest use of PCC behaviours. Nurse interactions were more likely to be characterized by more PCC behaviours (i.e. Class 3 or 4) (44.8%), followed by medical officers (33.9%) and clinical officers (27.3%) (p = 0.031). Longer interactions were also more likely to integrate more PCC behaviours (p < 0.001).Conclusions
PCC behaviours are relatively uncommon in HIV care in Zambia, and often limited to brief rapport-building statements and PCC micropractices. Strengthening PCC, such as shared decision-making and leveraging discretionary power to better accommodate client needs and preferences, may be an important strategy for improving the quality in HIV treatment programmes. 相似文献786.
