RESUMO

Haemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory syndrome characterised by persistently activated cytotoxic lymphocytes and macrophages, which, if untreated, leads to multiorgan dysfunction and death. HLH should be considered in any acutely unwell patient not responding to treatment as expected, with prompt assessment to look for what we term the three Fs-fever, falling blood counts, and raised ferritin. Worldwide, awareness of HLH and access to expert management remain inequitable. Terminology is not standardised, classification criteria are validated in specific patient groups only, and some guidelines rely on specialised and somewhat inaccessible tests. The consensus guideline described in this Health Policy was produced by a self-nominated working group from the UK network Hyperinflammation and HLH Across Speciality Collaboration (HiHASC), a multidisciplinary group of clinicians experienced in managing people with HLH. Combining literature review and experience gained from looking after patients with HLH, it provides a practical, structured approach for all health-care teams managing adult (>16 years) patients with possible HLH. The focus is on early recognition and diagnosis of HLH and parallel identification of the underlying cause. To ensure wide applicability, the use of inexpensive, readily available tests is prioritised, but the role of specialist investigations and their interpretation is also addressed.

RESUMO

OBJECTIVE: To investigate the prevalence, describe the radiological features, and consider the clinical sequelae of COVID-19- associated shoulder girdle calcific myositis. METHODS: All patients who underwent a CT pulmonary angiogram study at our institution (Queen Alexandra Hospital, Portsmouth Hospitals University NHS Trust, Portsmouth, United Kingdom) in April and May 2020, January 2021, and July 2021 were included. A total of 1239 CT pulmonary angiogram studies for 1201 patients were reviewed. Patients with COVID-19 and associated shoulder girdle calcific myositis were identified. Their electronic patient records were reviewed. The patients' demographics, serum inflammatory markers, and proning history were recorded. RESULTS: Of the 364 patients in Wave 1, 71 patients (19.5%) had COVID-19, and of those, 2 patients (2.8%) had shoulder girdle calcific myositis. Of the 521 patients in Wave 2, 354 patients (67.9%) had COVID-19, and of those, 3 patients (0.8%) had shoulder girdle calcific myositis. Of the 316 patients in Wave 3, 37 patients (11.7%) had COVID-19, and of those, 1 patient (2.7%) had shoulder girdle calcific myositis. The overall prevalence was 1.3%. The most common site of calcific myositis was within the subscapularis muscle. CONCLUSION: COVID-19-associated shoulder girdle calcific myositis is a rare extrapulmonary musculoskeletal manifestation of COVID-19. Early recognition and increased awareness of this disease entity, in our experience, aids in reducing patient morbidity and improving long-term functional outcome. ADVANCES IN KNOWLEDGE: We have reported a novel disease entity associated with COVID-19, in the form of shoulder girdle calcific myositis. We have described the common imaging features and discussed our experience of management and clinical sequelae.

RESUMO

COVID-19 related calcific myositis is a novel entity which is not well established in the literature to date. At Portsmouth, we encountered two cases during the initial peak of the pandemic that appeared to have similar clinico-radiological features. Our cases highlight the importance of COVID-19 calcific myopathy as a potential cause of prolonged shoulder and upper limb girdle symptoms.

RESUMO

Symptomatic knee osteoarthritis (OA) can be viewed as the end result of a molecular cascade which ensues after certain triggers occur and ultimately results in irreversible damage to the articular cartilage. The clinical phenotype that knee OA can produce is variable and often difficult to accurately predict. This is further complicated by the often poor relationship between radiographic OA and knee pain. As a consequence, it can be difficult to compare studies that use different definitions of OA. However, the literature suggests that while there are multiple causes of knee OA, two have attracted particular attention over recent years; occupation related knee OA and OA subsequent to previous knee injury. The evidence of a relationship, and the strength of this association, is discussed in this chapter.
