Using WHO-FRAX to describe fracture risk: experience in primary care.

Ideally those at highest risk of fracture should be identified prior to fracture occurrence to reduce mortality, morbidity and costs. Case-finding strategies for those at high risk of first fracture or systematic case-finding strategies following fracture are recommended in the UK, rather than population-based screening to identify individuals at high fracture risk. General practices in the UK hold relevant data on individuals beyond fracture history that could allow identification of a wider group of patients at highest risk of fracture. The aim of the paper is to evaluate the feasibility of applying the WHO-FRAX fracture risk calculator to general practice populations using existing recorded data. A cross-sectional study of 2467 women aged 50 years and older (mean 66.2 years, standard deviation = 11.3) registered with two Scottish General Practices with low deprivation (one semi-rural, one urban) was undertaken. Patient data were extracted from the two general practices' patient information databases and the WHO-FRAX calculator was applied to these data. WHO-FRAX calculation was possible on 1872 patients. Of these, 687 patients were found to have a high fracture risk (risk of major facture ≥15% and or risk of hip fracture ≥3% - 37% of the WHO-FRAX assessed cohort) and should be considered for follow-up. In conclusion, use of the WHO-FRAX calculator using general practice-held data is feasible and can help to identify a patient group at higher fracture risk. Further evaluation and treatments can then be targeted at this group.

Successful high dose therapy for relapsed mediastinal large B cell lymphoma following surgical repair of anterior chest wall defect.

We describe a man with relapsed large B cell mediastinal lymphoma and associated infected large anterior chest wall defect who required high dose salvage therapy for his underlying disease. An initial mediastinotomy wound, associated with recurrent sepsis, had developed into an abscess, then fistula and eventually a large anterior chest wall defect. Safe use of salvage chemotherapy required reconstructive surgery consisting of a pedicled muscle flap. The subsequent high dose chemotherapy was carried out without complications and 15 months later the patient is alive and well.

Hemorrhagic lymphadenopathy as a presenting feature of primary al amyloidosis.

Lymphadenopathy associated with hemorrhage as a presenting feature of primary (AL) amyloidosis has not previously been described. We report two such cases one of whom had an acquired factor X and IX deficiency. The clinical presentations were characterized by sudden spontaneous enlargement of lymph nodes followed by partial regression. In both cases significant delay in diagnosis, and hence treatment, occurred due to the mode of presentation. One patient died with rapidly progressive disease but the other has had an excellent response to therapy with high-dose melphalan (HDM, 200 mg/m2) and peripheral blood stem cell rescue. AL amyloid should be considered in all patients presenting with hemorrhagic lymphadenopathy.

Acute changes in urine protein excretion may predict chronic ifosfamide nephrotoxicity: a preliminary observation.

PURPOSE: To evaluate proteinuria occurring early after ifosfamide therapy and to assess the use of changes in proteinuria in the prediction of severe chronic nephrotoxicity. METHODS: One-dimensional sodium dodecyl sulphate polyacrylamide gel electrophoresis was used to characterize urine protein excretion in 12 children with solid tumours before and after the first course of ifosfamide treatment, and in 24 healthy children. Chronic nephrotoxicity was evaluated at 6 months after ifosfamide treatment and graded as none, mild, moderate or severe. RESULTS: Urine from healthy children and from 10 of 12 patients before ifosfamide therapy showed a protein band with a molecular weight (95.4 kDa) corresponding to that of Tamm-Horsfall protein but no lower molecular weight proteins. After the first course of ifosfamide this 95.4-kDa protein was lost in six of ten patients with a concomitant appearance of a low molecular weight proteinuria (< 70 kDa) in eight. Tamm-Horsfall protein was lost in two of five patients who subsequently developed no or mild nephrotoxicity and in four of five patients who subsequently developed moderate or severe nephrotoxicity. CONCLUSIONS: Early subclinical changes in urine protein excretion after ifosfamide, manifested by a loss of Tamm-Horsfall protein excretion, may be predictive of subsequent chronic nephrotoxicity.

The relationship between bcl-2 expression and response to chemotherapy in acute leukaemia.

Immunocytochemistry was used to assess bcl-2 expression in blasts obtained from the bone marrow of 28 patients with acute lymphoblastic leukaemia (ALL) (16 children and six adults at presentation and three children and three adults on relapse) and 20 with acute myeloid leukaemia (AML) (19 adults and one child, 13 with de novo AML, 11 at presentation and two on relapse, and seven secondary to myelodysplasia or chronic myeloid leukaemia). Slides were examined both for the percentage of positive cells and for the intensity of staining using a five-point scale. There was a statistically significant increase in both the percentage of positive cells seen (P < 0.002) and the intensity of staining (P < 0.01) between samples obtained at relapse and those at presentation in ALL. There was a significantly greater intensity of staining in cells from patients with ALL (P < 0.05) and AML (P < 0.05) who failed to achieve remission after chemotherapy than in those who responded. The intensity of staining in cases of secondary AML was lower than that in de novo disease (P < 0.01). These results suggest that expression of bcl-2 may be an important prognostic feature in both de novo AML and in ALL, but not in secondary AML.
