    Notes: Abstract Bone single-photon emission tomography (SPET) was performed in 40 patients within 6 months of acute knee injury where internal derangement of the knee was suspected, and the results related to the arthroscopy findings. Scan features with high sensitivity, specificity, and predictive accuracy for a meniscal tear could not be obtained on planar imaging. However, a half-crescent or more of increased tibial plateau activity on transaxial SPET gave a sensitivity of 89%, a specificity of 76%, a positive predictive accuracy of 77% and a negative predictive value of 89%. For longitudinal (bucket handle) tears alone the optimum scan pattern was a full crescent of increased tibial plateau activity with adjacent femoral activity and increased blood pool activity which gave corresponding values of 78%, 94%, 78% and 93%. It is concluded that the inclusion of tibial plateau activity of less than a full crescent and the presence of femoral condyle and blood pool activity in the diagnostic criteria improves the ability of bone SPET to detect meniscal tears. The value of bone SPET in the diagnosis of meniscal tears suggests that it could have a significant role to play in the management of knee injuries.

    Notes: Abstract Forty-seven patients, 29 with chronic inflammatory bowel disease (1131) and 18 with presumed irritable bowel syndrome, including one with uncomplicated diverticular disease, were studied with simultaneous technetium-99m hexamethylpropylene amine oxime and indium-111 oxine labelled leucocyte scans performed at 1, 3 and 24 h. Twenty-seven patients with IBD had active disease as judged by clinical and laboratory criteria and all of these had positive scans with both agents. No false positive studies were obtained. The 1-h 99mTc-HMPAO WBC scans showed the same distribution to disease as the 3-h 111-In WBC scans, with no difference in intensity (P 〈 0.92); they showed more extensive disease (P 〈 0.02) and more intense uptake (P 〈 0.001) than did the 1-h 111-In scans. The 3-h 99mTc-HMPAO WBC scans showed more extensive disease (P 〈 0.002), with greater intensity (P 〈 0.0005), than did the 3-h 111In WBC scans. Physiological bowel activity on 3-h 99mTc-HMPAO WBC scans was present in 12 patients but was faint and did not interfere with assessment of disease extent and activity. It is concluded that in terms of isotope availability, radiation dosimetry and image quality, 99mTc-HMPAO is the agent of choice in detecting active IBD, with localization of disease possible at 1-h after re-injection and optimal resolution and definition of disease extent at 3 h. A negative scan reliably excludes active disease.

    Notes: Abstract Radionuclide therapy has a proven place in the management of patients with thyroid disease. Iodine-131 therapy has been established as both successful and safe in treating patients with thyrotoxicosis and thyroid malignancy. Protocols for patient treatment are now standardised, although some variation in practice exists across Europe. There remains much confusion as to which patients should be selected for treatment with radio-iodine for thyrotoxicosis and what dose should be administered. A review of the literature reveals that many of the theoretical hazards of treatment with radioiodine have not been encountered despite many years of usage. New therapies for medullary thyroid cancer are now being evaluated and recent promising developments are discussed in detail.

    Notes: Abstract Nineteen patients with angina were recruited in this study for comparison of two 1-day protocols (stress-4 h rest and rest-4-h stress) and a 2-day protocol of technetium-99m tetrofosmin single-photon emission tomography (SPET). All of them underwent coronary angiography before or after the study. Exercise stress-rest study and rest-stress study were performed on two consecutive days. Delayed imaging was performed before the rest injection on the 2nd day. The stress study on the 1 st day and rest study on the 2nd day were considered as a 2-day protocol. The 1-day stress-rest protocol had a sensitivity of 100% (18/18) and an accuracy of 100% (19/19) in diagnosing ischaemic heart disease. The 1-day rest-stress protocol had a sensitivity of 94.4% (17/18) and an accuracy of 94.7% (18/19). These differences were not statistically significant (P=0.5 for sensitivity and accuracy). There was also no statistically significant difference between the two protocols in the diagnosis of ischaemic heart disease in individual artery territories. For the left descending artery, sensitivity was 88.2% (15/17) vs 76.5% (13/17) (P=0.48) for the stress-rest and rest-stress studies respectively. For the left circumflex artery, sensitivity was 90% (9/10) vs 80% (8/10) (P=1) and specificity was 66.7% (6/9) vs 77.8% (7/9) (P=1) respectively. For the right coronary artery, the sensitivity was 100% (16/16) vs 94% (15/16) (P=1) respectively, while the specificity was 33.3% (1/3) in both studies. Three hundred and forty-two myocardial segments were analysed. The stress-rest and 2-day protocols showed no statistically significant difference in the overall identification of segments with reversible ischaemia (48/141 segments vs 48/141 segments) or in respect of individual artery territories. There was also no significant difference in the identification of reversible ischaemic segments between the rest-stress and 2-day protocols (48/141 segments vs 34/135 segments,P=0.14). Abdominal activity was seen in 36 studies and interpretation was affected in five of them. Five patients with 24-h delayed images were evaluated and 24 segments with washout were identified. It is concluded that99mTc-tetrofosmin is a valuable new tracer in the investigation of ischaemic heart disease. The 1-day stress-rest protocol is as good as the 1-day rest-stress protocol in diagnosing coronary heart disease. The 1-day protocols and the 2-day protocol display no difference in identifying segments with reversible ischaemia.

    Description / Table of Contents: Résumé Les résultats d'une étude intensive sur l'économie du bétail dans le Nord Darfour, qui a demandé douze mois d'observations sur des troupeaux sédentairs et transhumants, sont rapportés. Pour presque tous les paramètres intéressant la production, les performances du bétail sédentaire sont supérieures à celles du bétail de transhumance, mais dans l'ensemble la production paraît être stable sinon déclinante. Pour 1973, on estime que la population bovine de cette région a diminué de 7 p. 100. La quantité de viande produite par kilogramme de femelle reproductrice est de 0,057 kg chez les animaux d'élevage extensif et seulement de 0,023 pour les animaux sédentaires. Les moyennes des vêlages sont significativement plus élevées dans le secteur transhumant que dans l'autre, 65 p. 100 contre 40 p. 100 respectivement. Les morts dans le premier secteur atteignent 15 p. 100 contre 35 p. 100 dans le second. On conclut que la sédentarisation totale du bétail transhumant ne constitute pas de réponse valable au problème du bétail dans le Sud Darfour.
    Abstract: Resumen Se hace recuento de los resultados de un estudio económico ntensivo de doce meses de un número de hatos en el sector migratorio y sedentario del Sur de Sudan. En casi todos los parámetros de producción, la productividad de los animales en el sector migratorio es superior a la de los animales en el sector migratorio es superior a la de los animales del sector sedentario; pero en general la producción parece estar estática o en descenso. Durante 1973 se estima que la población de ganado del área ha descendido en un siete por ciento. La producción de carne por kilogramo de hembra en producción se calculó en 0·057 kg en el sector migratorio y de 0·023 kg. en el sector sedentario. El porcentaje de nacimientos es significativamente más alto, 65 por ciento, en el sector migratorio contra un 40 por ciento del sector sedentario. El porcentaje de mortalidad en el primer sector fue del 15 por ciento comparado con el 35 por ciento del sedentario. Se concluye que la inmobilidad del sector migratorio no es la respuesta a los problemas que afronta el sector ganadero del Sur de Darfur.
    Notes: Summary The results of an intensive 12 months study of a number of herds in the migratory and sedentary sectors of the livestock economy of Southern Darfur are recorded. In almost every production parameter the performance of the former is superior to that of the latter but, overall, production appears to be static or declining. During 1973 the cattle population of the area is estimated to have declined by 7 per cent. Meat production per kilogramme of breeding female was calculated to be 0·057 kg in the migratory sector but only 0·023 kg in the sedentary sector. Calculated calving rates are significantly higher at 65 per cent in the migratory sector than the 40 per cent of the sedentary sector. Deaths in the former sector were only 15 per cent compared with the 35 per cent of the latter. It is concluded that total settlement of the migratory sector is not the answer to the current problem of the livestock sector of Southern Darfur.
