RESUMEN
A 47 year old Caucasian female with a background of type 2 diabetes mellitus, hypothyroidism, and autoimmune hepatitis presented with a painful, pruritic, papular eruption in a photosensitive distribution across the upper chest, neck, face, dorsal hands and forearms. On examination, lesions coalesced into annular plaques each with an active, raised margin and an atrophic, yellow centre. Histopathology demonstrated an absence of mucin and elastophagocytosis with giant cells engulfing dermal elastin fibres. These histopathological features favoured a diagnosis of annular elastolytic giant cell granuloma (AEGCG). The patient was managed ciclosporin monotherapy 125 mg twice daily (3 mg/kg/day). At 8 week review, there was a marked improvement in the physical appearance of the dermatosis as well as diminishing of symptoms such as itch and cutaneous pain. AEGCG is a rare inflammatory dermatosis typically affecting sun-exposed sites. It has been proposed that AEGCG is triggered by a solar induced elastolysis however other theories suggest it is a primary granulomatous disorder and not a photodermatosis. AEGCG appears to be aligned to an autoimmune diathesis, indicated by its frequent association with autoimmune conditions such as Hashimoto's thyroiditis, vitiligo, giant cell arteritis and, as in our patient, auto-immune hepatitis. Diabetes mellitus occurring concurrently with AEGCG has also been observed, again like our patient. Histopathological features which distinguish AEGCG from granuloma annulare include absent mucin, absent necrobiosis, giant cells with more nuclei, non-palisading granulomata and marked loss of elastic tissue. AEGCG is often unresponsive to standard therapies. The literature indicates varying responses to photo-protection, topical/systemic/intralesional corticosteroids, and oral medications such as methotrexate, hydroxychloroquine, and dapsone. Few case reports have also documented improvement with ciclosporin. In aggressive forms of AEGCG, as in our patient, treatment with ciclosporin may be an effective intervention and should be initiated early in the disease.
RESUMEN
Background: Recording large-group lectures is commonplace in higher education, allowing students to access content asynchronously and remotely. With the move towards online learning during the COVID-19 pandemic, recording of small-group teaching sessions has also become increasingly common; however, the educational value of this practice is unknown. Methods: All medical students rotating through the Acute Medicine Department of a large teaching hospital were invited to enrol in the study. Consenting students were recorded for the second half of an online case-based learning (CBL) session. The recording was available for 6 months; viewing patterns were analysed. Students were sent a questionnaire after the session, asking them to reflect on the recorded and unrecorded halves of the session. Findings: Thirty-three students underwent recording in 12 separate groups; 31 students (94%) completed the questionnaire. All 31 respondents (100%) described the session as "useful" or "very useful". Twenty-four respondents (77%) recommended continuing to record small-group sessions and 17 (55%) reported being "likely" or "very likely" to watch the recording. Six respondents (19%) reported a negative impact of being recorded. During 6 months of follow-up, no students returned to view the recording for more than 1 minute. Conclusion: Despite positive feedback for the session and high student demand for ongoing recording, no students viewed the recording for any significant duration. One-fifth of students reported a negative impact of being recorded. The findings from this study do not support routine recording of small-group CBL sessions, even where demand for this may exist.

RESUMEN
Atopic eczema is a common and complex disease. Missing genetic hereditability and increasing prevalence in industrializing nations point toward an environmental driver. We investigated the temporal association of weather and pollution parameters with eczema severity. This cross-sectional clinical study was performed between May 2018 and March 2020 and is part of the Tower Hamlets Eczema Assessment. All participants had a diagnosis of eczema, lived in East London, were of Bangladeshi ethnicity, and were aged <31 years. The primary outcome was the probability of having an Eczema Area and Severity Index score > 10 after previous ambient exposure to commonly studied meteorological variables and pollutants. There were 430 participants in the groups with Eczema Area and Severity Index ≤ 10 and 149 in those with Eczema Area and Severity Index > 10. Using logistic generalized additive models and a model selection process, we found that tropospheric ozone averaged over the preceding 270 days was strongly associated with eczema severity alongside the exposure to fine particles with diameters of 2.5 µm or less (fine particulate matter) averaged over the preceding 120 days. In our models and analyses, fine particulate matter appeared to largely act in a supporting role to ozone. We show that long-term exposure to ground-level ozone at high levels has the strongest association with eczema severity.
RESUMEN
Evidence shows dwindling levels of bedside teaching for medical students in the UK, especially in district general hospitals. Lack of individual responsibility has resulted in disengagement in teaching. Based on a quality improvement project (QIP) at a District General Hospital, we suggest some ways this could be addressed. We suggest here that harnessing support from the medical education lead, incentivizing teaching, allocating student-junior doctor groups to harbor personal responsibility, providing a supportive framework, and educating about barriers to teaching can all be used to develop an effective teaching program.
RESUMEN
CONTEXT: Verbal descriptors are important in understanding patients' experience of breathlessness. OBJECTIVES: The aim of this study was to examine the association between selection of breathlessness descriptors, diagnosis, self-reported severity of breathlessness and self-reported distress due to breathlessness. METHODS: We studied 132 patients grouped according to their diagnosis of advanced chronic obstructive pulmonary disease (n = 69) or advanced cancer (n = 63), self-reported severity of breathlessness as mild breathlessness (Numerical Rating Scale [NRS] ≤ 3, n = 53), moderate breathlessness (4 ≤ NRS ≥ 6, n = 59) or severe breathlessness (NRS ≥ 7, n = 20), and distress due to breathlessness as mild distress (NRS ≤ 3, n = 31), moderate distress (4 ≤ NRS ≥ 6, n = 44), or severe distress (NRS ≥ 7, n = 57). Patients selected three breathlessness descriptors. The relationship between descriptors selected and patient groups was evaluated by cluster analysis. RESULTS: Different combinations of clusters were associated with each diagnostic group; the cluster chest tightness was associated with cancer patients. The association of clusters with patient groups differed depending on their severity of breathlessness and their distress due to breathlessness. The air hunger cluster was associated with patients with moderate or severe breathlessness, and the chest tightness cluster was associated with patients with mild breathlessness. The air hunger cluster was associated with patients with severe distress due to breathlessness. CONCLUSION: The relationship between clusters and diagnosis is not robust enough to use the descriptors to identify the primary cause of breathlessness. Further work exploring how use of breathlessness descriptors reflects the severity of breathlessness and distress due to breathlessness could enable the descriptors to evaluate patient status and target interventions.

Uterine NK cells are innate lymphoid cells (ILC) that populate the uterus and expand during pregnancy, regulating placental development and fetal growth in humans and mice. We have recently characterized the composition of uterine ILCs (uILCs), some of which require the transcription factor NFIL3, but the extent to which NFIL3-dependent cells support successful reproduction in mice is unknown. By mating Nfil3 (-/-) females with wild-type males, here we show the effects of NFIL3 deficiency in maternal cells on both the changes in uILCs during pregnancy and the downstream consequences on reproduction. Despite the presence of CD49a(+)Eomes(-) uILC1s and the considerable expansion of residual CD49a(+)Eomes(+) tissue-resident NK cells and uILC3s in pregnant Nfil3 (-/-) mice, we found incomplete remodeling of uterine arteries and decidua, placental defects, and fetal growth restriction in litters of normal size. These results show that maternal NFIL3 mediates non-redundant functions in mouse reproduction.
RESUMEN
OBJECTIVES: Breathlessness is common in patients with advanced cancer and almost universal in advanced chronic obstructive pulmonary disease (COPD), but studies suggest their experiences of breathlessness vary. This report builds on these studies by providing quantitative evidence of differences in respiratory health-related quality of life (HRQoL) between these groups. Further, it explores the validity of the Chronic Respiratory Questionnaire (CRQ) in patients with cancer. METHODS: The CRQ-Original was completed within baseline interviews for a randomised controlled trial of a palliative intervention for intractable breathlessness due to advanced disease. Independent samples Mann-Whitney U tests were performed to identify significant differences in median scores for the four CRQ domains (mastery, dyspnoea, emotional function, fatigue) in patients with advanced COPD (n=73) or advanced cancer (n=67). The Minimally Clinically Important Difference of 0.5 was applied to determine clinical significance. RESULTS: Patients with advanced COPD scored lower across all four CRQ domains. This was statistically significant for dyspnoea, mastery and emotional function (p<0.05), and clinically significant for the latter two, suggesting poorer respiratory HRQoL. CONCLUSIONS: Patients with breathlessness due to advanced COPD have worse respiratory HRQoL than those with advanced cancer. This may result from greater burden of breathlessness in COPD due to condition longevity, lesser burden of breathlessness in cancer due to its episodic nature, or variance in palliative referral thresholds by disease group. Our results suggest that greater access to palliative care is needed in advanced COPD, and that formal psychometric testing of the CRQ may be warranted in cancer.
