RESUMEN
OBJECTIVE: To highlight the usefulness of duplex ultrasonography in assessing the degree of limb ischaemia in patients with peripheral arterial occlusive disease (PAOD). METHODOLOGY: Duplex ultrasonography (B mode, Color flow and spectral Doppler analysis) was used to evaluate the degree of limb ischaemia in an elderly Nigerian woman with diabetes who had clinical features of severe PAOD RESULTS: The patient was found to have moderate and severe limb ischaemia in the right and left lower limbs respectively. She subsequently had a below the knee amputation of the left lower limb. CONCLUSION: Duplex ultrasound is advised as part of the pre-operative evaluation of patients with PAOD, in order to adequately localise the diseased arterial segment and degree of limb ischaemia. However, segmental Doppler pressures with ankle brachial analysis should be utilised as a screening tool in symptomatic patients.

Nasal mucociliary clearance (NMCC) time was measured in four groups of patients: asthmatics with allergic rhinitis, asthmatics without rhinitis, bronchiectasis and normal subjects. The saccharin method was used for the study. The NMCC time was prolonged significantly in the asthmatic groups and group with bronchiectasis when compared with control subjects (P less than 0.001). It is likely that the impaired mucociliary clearance is due to a combination of mucus abnormality and ciliary malfunction.
