Abstract
Inflammatory pseudotumour (IP), also known as inflammatory myofibroblastic tumour (IMT), is a rare lesion of the maxillofacial skeleton and a diagnosis by exclusion. We describe three cases which affected the maxilla, two women and one man of ages 67, 56 and 70 years at presentation. All showed the typical, rather non-specific histopathological features. IgG4-positive plasma cells varied greatly in prominence, and none of the three lesions expressed ALK-1. Both women responded to steroids and radiotherapy, though one also required azathioprine. Despite maxillectomy, radiotherapy, steroids and cyclophosphamide, the man suffered intracranial spread and succumbed to persistent disease. The cases described here demonstrate the clinicopathological difficulties presented by this entity and its aggressive, unpredictable behaviour.

Abstract
PURPOSE To evaluate the predictive value of N-terminal pro B-type natiuretic peptide (NT-proBNP) reference cut-off values as diagnostic markers for left ventricular systolic dysfunction (LVSD). STUDY DESIGN A retrospective study assessing the use of NT-proBNP in the diagnostic algorithm for the investigation of patients with suspected signs and symptoms of LVSD presenting to primary care. RESULTS A generic NT-proBNP cut-off (150 ng/l) value has similar negative and positive predictive valves, specificity and sensitivity compared to age and sex specific cut-off values. CONCLUSION When using NT-proBNP as a triage tool for screening patients with signs and symptoms suggestive of LVSD, a simple generic cut-off level is as effective as more complex age sex specific cut-off values.

Abstract
BACKGROUND Prior phase II trials have demonstrated the therapeutic activity of cytotoxic chemotherapy in mesothelioma. Currently there are few randomised data assessing the role of chemotherapy versus best supportive care (BSC) in the management of patients with stable symptoms after control of any pleural effusion. A policy of observation is often adopted over initial use of chemotherapy. In this prospective randomised trial we assess the use of early versus delayed cytotoxic therapy. The study opened in 1998, and closed in view of a competing national study (MSO 1) in 2003. METHODS Eligible patients had a performance status<or=2, life expectancy>3 months and had stable symptoms for at least 4 weeks prior to randomisation. Patients were randomised to receive immediate chemotherapy or initial BSC with the addition of chemotherapy at time of symptomatic progression. All patients received the same platinum-based chemotherapy regimen, MVP [mitomycin C 8 mg/m2 cycles 1, 2, 4 and 6, vinblastine 6 mg/m2, maximum 10 mg, and cisplatin 50 mg/m2 (or carboplatin AUC 5)], every 3 weeks for up to six cycles. RESULTS A total of 43 patients were recruited, of which 21 were randomised to the early treatment group and 22 to the delayed treatment group. The median ages were 59 years (range 50-78) and 67 years (range 48-75), respectively (P=0.1); other baseline parameters were well matched between the two groups. All 21 patients in the early group received chemotherapy versus 17 patients in the delayed group. Median time to symptomatic progression was 25 weeks in the early group compared with 11 weeks for the delayed group (P=0.1). Median survival was 14 months (1-year survival 66%) for the early group compared with 10 months (1-year survival 36%) for the delayed group (P=0.1). Quality of life was in general better maintained for early treatment and the health resources use was similar in both arms. CONCLUSIONS In this patient group, presenting with stable symptoms after control of pleural effusion, the early use of chemotherapy provided an extended period of symptom control, and in this small trial a trend to survival advantage.

Abstract
Hyperemic responses after arterial occlusion were investigated in patients with Raynaud's phenomenon due to systemic sclerosis (SSc) and in healthy controls. The hyperemia due to arterial occlusion for 2 min was measured by laser-Doppler flowmetry. If the hyperemic response was absent, the measurements were repeated after vasodilatation was induced by hand warming in warm water. Reactive hyperemia was absent in 12 patients when investigations were performed on the unwarmed hand, and these patients had very low resting blood flows. After vasodilatation was induced in these patients, and also in those patients whose resting blood flow was normal, hyperemic responses were comparable in magnitude with those in the controls. The slope of the hyperemic response was significantly less in the patients (1.11 +/- 0.02 V/s) than in the controls (1.28 +/- 0.03 V/s), and therefore, the time course of the hyperemia was lengthened in the patients with SSc, with a delay to achieving maximum blood flow of 2 min. Peak blood flow was directly related to the level of the initial blood flow. These findings support the view that reactive hyperemia is principally a mechanical phenomenon, and also that vessel wall reactivity is abnormal in SSc, producing delayed hyperemic responses. The magnitude of the hyperemia depends on initial flow rates, and the apparent lack of these responses in SSc is a result of their low, but reversible, resting blood flow.

Abstract
Clinical and serological evidence of connective tissue disease was found in a high proportion of 132 family members of 30 patients with systemic sclerosis. In 20 probands with the milder CREST form of the disease, 10 had HLA-DR5 and 12 had null alleles at the C4 loci. None of 11 probands with more severe systemic sclerosis had HLA-DR5; all 11 had null alleles at the C4 loci. All but two of the probands had either HLA-DR5 or a C4 null allele, and this was also the case for the majority of the relatives with autoantibodies. Genetic markers of the major histocompatibility complex, including HLA-DR5 and C4 null alleles, appear to be closely associated with markers of disease in these probands and their families.

Abstract
The danger of superficial radiotherapy for benign dermatoses has been exaggerated. It is safe if certain precautions are observed. The permissible life time maximum cumulative dose of conventional superficial X rays generated at 50 kV given to any area of skin is 1000 R, and of grenz rays, 5000 R.

Abstract
Four patients presenting with painful persistent cyanosis or gangrene of the fingers were found to have anomalies of arterial circulation of the hands and fingers. Investigations for systemic disease were negative. It is postulated that variations in the normal arterial anatomy predispose to digital ischaemia and that trauma, the contraceptive pill or infection may precipitate small thromboses and give rise to clinical ischaemia. Angiography should be undertaken in all patients presenting with persistent ischaemia of the fingers and toes, when the peripheral pulses are present and systemic disease has been excluded.
