Papers with varying international flavour and input appear in this issue of the SAMJ, illustrating our growing reach of readers and contributors. Reversible nephrotic syndrome secondary to pulmonary hydatid disease provides an interesting ‘Clinical Images’ topic from Tunisia. (1) Most patients with hydatidosis are children. The disease may be asymptomatic or revealed by unusual events such as glomerulopathy. Gargah and colleagues describe an 8-year-old boy who presented with generalised oedema and macroscopic haematuria. Radiology revealed three large hydatid cysts in the lungs. Renal biopsy showed characteristics of mesangiocapillary glomerulonephritis. He recovered well following medical and surgical treatment of the hydatid disease. The authors believe that their observation is the first in a child in the first decade.
