Anaemia still persists among children and women of childbearing age in Palestine. We investigated the prevalence of anaemia and associated factors among Palestinian school adolescents (aged 13-15 years) in Ramallah and Hebron governorates. Haemoglobin levels were measured to assess the prevalence of anaemia. The prevalence of anaemia was significantly higher in Hebron than in Ramallah among boys (22.5% versus 6.0% respectively), while among girls the figures were similar (9.2% and 9.3% respectively). Linear binomial regression analysis showed that among boys, anaemia was independently associated with residence in Hebron and higher standard of living, while among girls, anaemia was associated with higher father's education. Consumption of iron-rich foods, as recorded in food frequency questionnaires, had no significant effects on anaemia prevalence in both boys and girls.

Studies show that treatment with apremilast results in significant improvement in both skin psoriasis and PsA symptoms. Apremilast has been approved by both the United States FDA and European Medicines Agency for treatment of PsA. Use of this medication is recommended in active PsA patients, according to local licensing.

ObjectivesTo evaluate the risk of association with hip osteoarthritis (OA) of 14 morphological features measured on standard antero-posterior pelvis radiographs.MethodsA case–control study of 566 symptomatic unilateral hip OA cases and 1108 controls without hip OA, using the Genetics of OA and Lifestyle database. Unaffected hips of cases were assumed to reflect pre-OA morphology of the contralateral affected hip. ORs with 95% CI adjusted for confounding factors were calculated using logistic regression. Hierarchical clustering on principal component method was used to identify clusters of morphological features. Proportional risk contribution (PRC) of these morphological features in the context of other risk factors of hip OA was estimated using receiver operating characteristic analysis.ResultsAll morphological features showed right–left symmetry in controls. Each feature was associated with hip OA after adjusting for age, gender and body mass index. Increased sourcil angle had the strongest association (OR: 6.93, 95% CI 5.16 to 9.32). Three clusters were identified. The PRC varied between individual features, as well as between clusters. It was 35% (95% CI 31% to 40%) for all 14 morphological features, compared to 21% (95% CI 19% to 24%) for all other well-established risk factors.ConclusionsConstitutional morphological variation strongly associates with hip OA development and may explain much of its heritability. Relevant morphological measures can be assessed readily on standard radiographs to help predict risk of hip OA. Prospective studies are required to provide further support for causality.

A 36-year-old woman presented to hospital 9 days after receiving her first dose of the ChAdOx1 nCoV-19 vaccine with fever, myalgia and a sore throat. She was previously fit and well with no prior vaccine reactions.There was no clinical response to initial treatment with intravenous (IV) antibiotics. Microbiology tests including for COVID-19 were negative. At day 5, she developed pleuritic pain and a pericardial rub. Echocardiography and subsequent cardiac magnetic resonance imaging showed evidence of constrictive pericarditis. Computed tomography revealed gross hepatomegaly and moderate splenomegaly. Blood tests showed raised inflammatory markers, deranged clotting, low platelets and a marked hyperferritinaemia.A presumptive diagnosis of a multi-system inflammatory disorder secondary to recent COVID-19 vaccination was made and high-dose IV methylprednisolone initiated. Following a high 'H score' of 70%-80% a diagnosis of secondary haemophagocytic lymphohistiocytosis (HLH) was made. She was treated with IV immunoglobulin with subsequent clinical response.HLH is a rare syndrome of acute and rapidly progressive systemic inflammation characterised by cytopenias, excessive cytokine production and hyperferritinaemia. The adult form has multiple triggers, including recent vaccination. This case prompts awareness among clinicians of HLH as a rare complication of COVID-19 vaccination but should not discourage individuals from vaccination.
