Anaplastic bone lymphoma presenting as isolated back pain

A previously healthy man in his late 20s presented with a 4-week history of insidious back pain and raised inflammatory markers. Various specialists were involved in his care including general physicians, orthopaedic surgeons and rheumatologists. After numerous investigations including imaging and two bone biopsies, an unexpected diagnosis of anaplastic large cell lymphoma emerged. This case illustrates the importance of investigating back pain with red flags thoroughly using different imaging modalities and where indicated a bone biopsy.

Thermal characteristics of rheumatoid feet in remission: Baseline data

Objectives

Studies have shown conflicting characteristic thermographic patterns of the feet in patients with active rheumatoid arthritis (RA). However, to date no studies have compared thermographic patterns of patients with RA in remission and healthy controls. Thus this study aimed to investigate whether the thermal characteristics of the feet of RA patients, in clinical and radiological remission differ to those of healthy controls.

Methods

Using convenience sampling, RA patients were recruited upon confirmed absence of synovitis by clinical examination and musculoskeletal ultrasound. Thermal images of the feet were taken. Each foot was subdivided into medial, central, lateral, forefoot and heel regions. Subsequently, temperatures in the different regions were analyzed and compared to a cohort of healthy adults.

Results

Data from 32 RA patients were compared to that of 51 healthy controls. The Independent samples T-Test demonstrated a significant difference in temperatures in all the regions of the forefoot between RA participants versus healthy subjects (Table 1). Using the One-Way ANOVA test, no significant difference was found between all the forefoot regions (p = 0.189) of RA patients. Independent sample T-test found significant differences in all heel regions between the two groups (Table 2). One-Way ANOVA demonstrated no significant differences (p = 0.983) between the different foot regions (n = 192) of RA patients.

Conclusion

These findings suggest that RA patients in clinical and radiological remission exhibit significantly different feet thermographic patterns compared to healthy controls. This data will provide the basis for future studies to assess whether thermographic patterns change with disease activity.

The Epidemiology and Outcomes of Septic Arthritis in the Maltese Islands: A Hospital-Based Retrospective Cohort Study

Objective/Aim:

Septic arthritis is an uncommon but important disease with significant morbidity and mortality, especially if inadequately managed. The aim of this epidemiological study was to identify the characteristics and outcomes of patients treated for septic arthritis at Mater Dei Hospital, Malta, over a 10-year period.

Methods:

This was a retrospective observational study. Patients diagnosed with septic arthritis between 2008 and 2018 were recruited. Cases were identified by reviewing all inhospital episodes of patients diagnosed with septic arthritis according to Newman criteria.

Results:

There were 124 cases of native joint septic arthritis and 138 of prosthetic joint infection. Cases were present amongst all age groups, with the highest incidence amongst those aged 61–70 years for both native and prosthetic infections. Fever was present in around 40% of cases. Raised white cell count was prevalent in 66.9% of native joint infections and 52.9% of prosthetic joints. Elevated C-reactive protein was overwhelmingly seen in most cases, present in 93.5% (median=159.5 mg/L; IQR=85.8–291) of native joints and 92.0% of prosthetic joint infections (median=68.7 mg/L; IQR=20.5–186). Over 55% of patients had one or more risk factors for joint sepsis, diabetes mellitus being the most prevalent clinical comorbidity (22.6% and 24.6% for native and prosthetic joint infections respectively). Synovial cultures were positive in 66% and 82% of native and prosthetic joint aspirates respectively. Staphylococcus aureus was the most commonly isolated organism from both native and prosthetic joint infection, followed by streptococcal infections in native joints and coagulase negative staphylococci and gram-negative infections in prosthetic joints. Fifteen deaths were directly attributed to joint sepsis.

Conclusion:

Absence of fever and elevated white cell count does not exclude the diagnosis. The mortality rate due to septic arthritis in this cohort of patients was found to be 5.7%. All deaths occurred in elderly patients with clinical comorbidities suggesting that this group is at highest risk.

Patients' perspective of a dedicated biologic clinic for inflammatory arthritis

PURPOSE

The purpose of this paper is to assess the patient's perspective on a dedicated clinic set up for patients diagnosed with an inflammatory arthritis who are being treated with a biologic. It proposes that dedicated clinics offer better overall care. The aim of this quality improvement survey is to evaluate the level of patient satisfaction with this clinic and identify any unmet needs.

DESIGN/METHODOLOGY/APPROACH

This study was based on a quality improvement survey, which was developed using Zineldin's five qualities model and assessed various aspects pertaining to service quality and improvement. A structured interview approach was used and 44 consecutive patients were recruited.

FINDINGS

This paper explores key aspects that influence patient satisfaction within a rheumatology outpatient setting such as education on arthritis and biologics and involvement in decision making. It provides insight on what patients value most and it also addresses organizational aspects that can have an impact on patient satisfaction. It suggests that service quality can be linked to the degree of patient satisfaction.

RESEARCH LIMITATIONS/IMPLICATIONS

Direct interviewing of patients could have introduced a source of bias whilst questions are being answered. On the other hand, it provided an opportunity to clarify instantly any doubts and therefore avoiding any inadvertent errors.

PRACTICAL IMPLICATIONS

This paper reinforces that specialized clinics enable the caring rheumatologist to provide better care for patients on biologics. Service providers should continue developing their services around the patient's needs and perspectives in order to continue improving the service.

SOCIAL IMPLICATIONS

Dedicated biologic clinics allow more judicious monitoring of patients who are taking these highly efficacious but costly medications.

ORIGINALITY/VALUE

This survey has reinforced that patients highly value dedicated clinics. These results strengthen the case that healthcare services should continue investing on specialized clinics.

A comparison of thermographic characteristics of the hands and wrists of rheumatoid arthritis patients and healthy controls

Thermal imaging has been applied to detect possible temperature variations in various rheumatic disorders. This study sought to determine whether rheumatoid arthritis (RA) patients without active synovitis in their hands exhibit different baseline thermographic patterns of the fingers and palms when compared to healthy individuals. Data from 31 RA patients were compared to that of 51 healthy controls. The RA patients were recruited upon confirmed absence of synovitis by clinical examination and musculoskeletal ultrasound. Participants underwent medical infrared imaging of the regions of interest (ROIs). Significant differences were found between the mean temperatures of the palm regions (29.37 °C (SD2.2); n = 306) and fingers (27.16 °C (SD3.2); n = 510) of the healthy participants when compared to the palm regions (31.4(SD1.84)°C; n = 186) and fingers (30.22 °C (SD2.4); n = 299) of their RA counterparts (p = 0.001), with the latter group exhibiting higher temperatures in all ROIs. Logistic regression models confirm that both palm and finger temperature increase significantly in RA without active inflammation. These innovative findings provide evidence that baseline thermal data in RA differs significantly from healthy individuals. Thermal imaging may have the potential to become an adjunct assessment method of disease activity in patients with RA.

Catastrophic antiphospholipid syndrome in pregnancy: a life-threatening condition

Catastrophic antiphospholipid syndrome (CAPS) is a rare and potentially life-threatening variant of the antiphospholipid syndrome which is characterised by multiple small vessel thrombosis which can lead to multiorgan failure. CAPS is a clinical emergency which all clinicians need to be aware of because early diagnosis and treatment may improve maternal and fetal outcome. Here, we report a case of CAPS in pregnancy in a 31-year-old female patient who presented at 28 weeks of gestation. A literature review of CAPS in pregnancy and the puerperium is also included.

Dyspnoea in lupus

A 32-year-old woman suffering from systemic lupus erythematosus presented with a 6-week history of progressive dyspnoea and pleuritic chest pain. Examination was normal apart from reduced air entry at the lung bases.Arterial blood gases showed hypoxaemia and chest X-ray revealed raised hemidiaphragms without any pleural effusions. Lung function showed a restrictive pathology while high-resolution chest CT and CT pulmonary angiogram were negative. Echocardiography showed normal ventricular diameters and no pericardial effusion. Reduced lung volumes and a positive fluoroscopic sniff test lead to a diagnosis of shrinking lung syndrome. Symptoms improved following treatment with glucocorticoids and non-invasive ventilation, but there was no change in lung function.A year later, our patient presented again with worsening dyspnoea. This time echocardiography revealed severe mitral stenosis with pulmonary hypertension. Mitral valve replacement was performed and dyspnoea resolved. Histology showed Libman-Sachs endocarditis.

Can rheumatologists diagnose and manage Giant Cell Arteritis better than non-rheumatologists? The Maltese Experience

OBJECTIVES:

Giant Cell Arteritis (GCA) remains a challenge both in terms of diagnosis and management as patients may present to several different specialists. The objectives were to determine incidence of biopsy-proven GCA in Malta and to compare the management between rheumatologists and non-rheumatologists.

METHODS:

This was a retrospective observational population study of patients with suspected GCA who underwent a temporal artery biopsy (TAB) between 2012 and 2015. Data collected consisted of demographics, presenting symptoms, TAB histology reports, treatment and outcome. The British Society for Rheumatology (BSR) 2010 guidelines were used as standard of care.

RESULTS:

136 patients underwent a TAB for suspected GCA of which 26 were positive. The incidence of biopsy-proven GCA in Malta was 3.82 per 100,000 patient years in the over 50 population. There were 63 patients who were treated as GCA. Only 43.3% of confirmed cases had rheumatology input. TABs requested by rheumatologists were twice more likely to be positive compared to requests by non-rheumatologists (30.5% vs. 14.1%).The majority of patients were started on a Prednisolone dose between 40–60mg. Rheumatologists maintained patients on high doses for at least 1 month in 54% of cases as opposed to 20% under non-rheumatologists. Monitoring was more regular for cases followed up by rheumatologists (40% vs. 21%).

CONCLUSIONS:

Malta has a low incidence of biopsy proven GCA. Although rheumatologists are more likely to adhere to the recommended guidelines, improvement is needed. Rheumatologists should take the lead to minimise variation and optimise management of GCA.

Pulmonary, renal and neurological comorbidities in patients with ankylosing spondylitis; implications for clinical practice

Ankylosing spondylitis (AS) is associated with several comorbidities which contribute significantly to morbidity and mortality and add to the complexity of management. In addition to the well known extra-articular manifestations and increased cardiovascular risk, several pulmonary, renal, and neurological complications which have been associated with AS deserve equal attention. Whereas a clear link has been established for some manifestations, the evidence for other associations is less clear. Interstitial lung disease, apical fibrosis, secondary infection, and ventilatory restriction from reduced chest wall movement are well known pulmonary complications; more recently an association with sleep apnoea has been suggested. Renal amyloidosis and IgA nephropathy remain a treatment challenge which may respond to anti-TNF therapy. Atlanto axial subluxation and vertebral fractures can result in serious neurological complications and are notoriously difficult to diagnose unless a high level of suspicion is maintained. Despite several reports linking AS with demyelination a true link remains to be proved. This review discusses the prevalence, pathophysiology, and management of pulmonary, renal, and neurological complications, and implications for clinical practice.

The intelligent use of systemic glucocorticoids in rheumatoid arthritis

Glucocorticoids (GC) have potent anti-inflammatory and immunomodulatory effects and are widely used in the management of rheumatoid arthritis in combination with other disease-modifying anti-rheumatoid drugs. Concern about the risk of adverse effects may be to some extent misplaced as low to moderate doses of GC have different mechanisms of action and risk profiles compared with high doses. This review discusses the current understanding about the different modes of action of GC, their strong disease-modifying properties and the efforts at improving the therapeutic ratio of GC through the development of new drugs which promise greater safety such as selective GC receptor agonists, liposomal GC and modified-release (MR) prednisone.

Prevalence and incidence of pituitary adenomas: a population based study in Malta

Epidemiological data is important to correctly quantify the extent of disease and needed health care resources. The aim of the study was to establish the prevalence and incidence of pituitary adenomas (PAs) in the same well defined population, with in-depth analysis of the various subtypes. The design involved a retrospective cross-sectional analysis of PA patients diagnosed prior to 31 July 2011 for prevalence estimates and those diagnosed between July 2000 and July 2011 for incidence estimation. A thorough search for patients with PAs was carried out in central hospital registries including outpatients departments, surgical registries, radiological department and specialty clinic databases. Prevalence rates/100,000 and Standardised incidence ratios (SIR)/100,000/year were worked out. The respective prevalence rates and SIR for PAs overall were 75.7/100,000, and 4.27/100,000/year, for Prolactinomas 35.0/100,000 and 2.05/100,000/year, for nonfunctioning PA 25.9/100,000 and 1.79/100,000/year and for GH-secreting PAs 12.5/100,000 and 0.31/100,000/year. The overall prevalence for macroadenomas was 32.8/100,000 and SIR was 1.49/100,000/year. The prevalence rate in males for PAs overall was 46.3/100,000 and SIR was 2.08/100,000/year and in females 104.8/100,000 and SIR was 6.58/100,000/year. Females had a lower proportion of macroadenomas than males (29.5 vs. 75.0%; P < 0.001) and macroadenomas tended to present at a later age compared to microadenomas (48 vs. 34.5; P < 0.001). The highest SIR was reached in the 30-39 age group at 7.42/100,000/year. Our data confirm the considerable disease burden that PAs bear on health care resources. Males and females have similar prevalence and SIR rates for macroadenomas but there is a significant increase in SIR in females of child bearing age compared to males. These observations may have important implications in terms of the economic burden and need for early intervention.

Freedom of movement across the EU: legal and ethical issues for children with chronic disease

While freedom of movement has been one of the most highly respected human right across the EU, there are various aspects which come into play which still need to be resolved for this to be achieved in practice. One of these key issues is cross border health care. Indeed, there is an increasing awareness of standardisation of health service provision and cross border collaboration in the EU. However, certain groups particularly children may be at risk of suboptimal treatment as a result. We present the case of a child patient which highlights the complexity of this matter spanning family law, health law, social security law as well as ethical issues. EU legislation needs to ensure that children patients have access to high quality care across the EU borders.
