Background An initial pilot study of 300 sub-Tenon local anesthetic blocks (STBs) for intraocular surgery established the effectiveness and patient acceptability of the technique. Following this, a decision was made in 1995 to change from sharp needle techniques to STB for all eye surgeries performed during local anesthesia at Auckland Hospital (Auckland, New Zealand) by reeducation of anesthetists and surgeons. At this point, sufficient data were not available to confirm that STB would avoid the complications associated with the passage of sharp needles into the orbit or would cause a different set of serious complications. Methods A prospective study of the next 6,000 consecutive STBs performed at Auckland Hospital was carried out over a period of 6 yr (from 1995 to 2000). Results Sub-Tenon block is very effective, with a surgeon and patient acceptability rate of 98.8%. Insertion of the sub-Tenon cannula and administration of the anesthetic produces minimal discomfort, being completely painless in 68.8% of cases. There were no serious block-related complications in this series, supporting the safety of the sub-Tenon technique. Conclusion The experience at Auckland Hospital provides further support for the avoidance of passing sharp needles into the orbit.

A review of the studies on the use of the antigen-antibody system HMW-MAA 225.28S in melanoma radioimmunodetection is reported. The results obtained in a pilot study (42 patients with 74 lesions), a multicenter trial (254 patients with 553 lesions) and a prospective study still outstanding (29 patients with 38 lesions) allow to consider this system as suitable for clinical application. F(ab′)2 labelled with 99mTc gave the best results in terms of positivity. Moreover this radioisotope allows the best dosimetric conditions. The gamma energy emitted by this radionuclide is particularly convenient for conventional scintillation cameras and ECT. Very good results in terms of sensitivity (70%-85%) and especially specificity (about 100%) were achieved. Possible clinical applications of the method are discussed.

Based on the experience with the International Pilot Study on Schizophrenia (IPSS) (WHO 1973, 1979), the WHO Division of Mental Health and Centres in Sofia, Groningen and Mannheim, joined by expertise from Nottingham and Zurich, conceived a prospective study to assess the ‘natural history’ (Ciompi, 1980a, b; Watt et al, 1983; Biehl, 1987) of psychological impairments and social disabilities in patients with functional psychosis in different socio-cultural environments (Jablensky et al 1980).
