    Notes: Summary The Welsh Community Diabetic Retinopathy Study was designed to assess the effectiveness of the Field Guide Book for screening for diabetic retinopathy in Europe. A community-based sample (prevalence 2 %) of diabetic patients was recruited from four general practices. Standardised training and equipment were provided. All patients were invited to attend practice-based screening sessions on two occasions over 3 years (phases 1 and 2). After mydriasis, clinical ophthalmoscopy was performed by a study optometrist and general practitioners (GPs). 2 × 45 ° field 35 mm retinal slides were obtained according to EURODIAB protocol. Anonymised slides were assessed by GPs, diabetologists and the optometrist. All the findings were graded externally (reference standard). In phase 2 community optometrists also performed ophthalmoscopy and assessed photographs. For detecting sight threatening diabetic retinopathy using ophthalmoscopy, GPs achieved a sensitivity of 65.7 %, specificity 93.8 % and positive predictive value (PPV) 65.7 %. Community optometrists achieved a sensitivity of 82.2 % with a PPV of 50.7 %; the study optometrist 79.2 and 55.9 %, respectively. The use of 35 mm slides improved sensitivity for the detection of sight threatening retinopathy to 87.3, 91.1 and 97.2 % for GPs, community optometrists and the study optometrist, respectively. PPV fell to 51.2 % for GPs, 40.6 % for community optometrists, but increased to 58.8 % for the study optometrist. Diabetologists achieved a sensitivity of 88.7 % and a PPV of 65.6 %. It is concluded that the European field guide is an effective tool for screening for retinopathy in clinical practice. [Diabetologia (1998) 41: 59–64]

    Notes: A commonly used in vitro assay of protein digestibility depends upon the measurement of pH change as the protein is digested by a multi-enzyme preparation. This report presents evidence demonstrating that the buffering capacity of the protein under assay can have a major effect on the digestibility value assigned using this method. A modification of the assay using an automatic titrator has overcome this problem.

    Notes: A clinical study was undertaken to investigate changes in the immune response in patients undergoing three differing anaesthetic techniques for inguinal hernia repair. No significant differences between anaesthetic groups were demonstrated in the haematological parameters. The value of mitogen stimulation tests was questioned in the clinical setting. The migratory component of neutrophil function was shown to be preserved following conduction anaesthesia compared to the other anaesthetic groups and its possible advantage noted.

    Description / Table of Contents: Résumé La melioïdose humaine est endémique en Asie du Sud-Est et en Australie tropicale. Toutefois, des rapports d'un nombre accru de cas arrivent d'autres parties du monde. L'accroissement des voyages de par le monde et le potentiel de l'infection de personne à personne dans les régions non-endémiques sont vraisemblablement responsables du fait que les médecins et les microbiologistes médicaux rencontrent la maladie plus souvent qu'auparavant. Tant la maladie, la melioïdose que l'organisme que la cause,Pseudomonas pseudomallei ont des caractéristiques inhabituelles, qui les rendent dignes de considération. Dans cette revue, on passe en revue la microbiologie dePseudomonas pseudomallei. On présente des études originales en présence de fimbriae et les facteurs qui influencent la pathogénicité de l'organisme sont discutés. On dècrit les propriétés des diverses endotoxines. On résume les connaissances actuelles vétérinaires et médicales relatives à la maladie. On attire l'attention sur ces faits — la latence prolongée, la multiplicité de symptômes, le manque de diagnostic spécifique — qui rendent le diagnostic difficile. Finallement, on détaille la technique ELISA pour la détection de la toxine dePseudomonas pseudomallei. Cette dernière pourrait bien être une méthode pour l'examen rapide des patients, permettant à une thérapeutique appropriée d'être mise en place au moment le plus précoce.
    Abstract: Resumen La melioidosis humana es una enfermedad endémica en el Sureste Asiático y en la zona tropical de Australia. Sin embargo se ha observado un incremento del número de casos en otras partes del mundo. La posibilidad de que médicos y microbiólogos puedan encontrarse con esta enfermedad en zonas no endémicas es cada vez mayor debido al incremento en la frecuencia y el número de personas que viajan y a la posibilidad de contagio persona a persona. Tanto la enfermedad, melioidosis, como el organismo causal,Pseudomonas pseudomallei, tienen peculiaridades que los hacen dignos de estudio. En esta revisión se presentan las características microbiológicas dePsedomonas pseudomallei, junto con estudios originales sobre la presencia de ‘fimbriae’ y se discuten los factores que influyen sobre la patogenicidad del organismo. Se describen las propiedeades de varias ‘exotoxinas’. Se subrayan los conocimientos médicos y veterinarios relacionados con la enfermedad. Se llama la atención sobre las características que dificultan el diagnóstico, como: periodo de latencia prolongado, multiplicidad de síntomas y carencia de un procedimiento de diagnóstico específico. Por último se describe detalladamente una técnica ELISA para la detección de toxinas dePseudomonas pseudomallei que puede representar un método de diagnóstico rápido que permita aplicar la terapeutica apropiada sin demoras.
    Notes: Summary Human melioidosis is endemic in South East Asia and tropical Australia. However, increasing numbers of case reports are coming from other parts of the world. Increasing world travel and the potential for person-to-person infection in non-endemic areas make the likelihood of physicians and medical microbiologists encountering the disease far greater than heretofore. Both the disease, melioidosis, and the causative organism,Pseudomonas pseudomallei, have unusual features which render them worthy of consideration. In this review, an overview is given of the microbiology ofPseudomonas pseudomallei. Original studies on the presence of fimbriae are presented and factors influencing pathogenicity of the organism discussed. Descriptions of the properties of the various ‘exotoxins’ are presented. Current veterinary and medical knowledge relating to the disease is outlined. Attention is drawn to those features—prolonged latency, multiplicity of presenting conditions and lack of a specific diagnostic characteristic—which make diagnosis difficult. Finally, details of an ELISA technique for the detection ofPseudomonas pseudomallei toxin are described. This may represent a method for rapid screening of patients allowing appropriate therapy to begin at the earliest moment.
