    Notes: Summary In a multinational study, fasting plasma glucose values in 3583 diabetic patients, aged 34–56 years, were related to the characteristics of these subjects and to the presence and severity of microangiopathy as ascertained by standardised methods. The patients were from nine different populations and ranged in number from 193 to 686 per population (London, Warsaw, Berlin (FRG), New Delhi, Tokyo, Havana, Oklahoma Indians, Arizona Pima Indians, and a national sample in Switzerland). In the total group, mean fasting plasma glucose was 8.1 mmol/l for those on diet alone, 9.7 mmol/l for those on oral agents, and 12.7 mmol/l for insulin-treated patients, of whom 25% had values exceeding 16.5 mmol/l. Since many variables were measured in each patient, it was possible to take into account many confounding factors in evaluating the relationship of plasma glucose levels to retinopathy and nephropathy.

    Notes: Abstract Six children with untreated congenital adrenal hyperplasia (CAH) were examined by computed tomography (CT). Three cases demonstrated diffuse enlargement of both adrenal glands with preservation of normal configuration and two showed tumorous transformation in one of the enlarged glands. One had equivocal enlargement of the adrenal gland. Even the youngest in this group (age 2 years) also showed bilateral hyperplasia.

    Description / Table of Contents: Résumé Quatre-vingts patients diabétiques et 20 sujets normaux âgés de moins de 40 ans, de l'All-India Institute of Medical Sciences Hospital, New Delhi, ont été soumis à unscreening pour vérifier la présence de vasculopathies; on a également recherché d'éventuelles relations avec les triglycérides, les pré-bêta-lipoprotéines et la lipoprotéin-lipase du sérum. La fréquence de vasculopathies (hypertension, rétinopathie, maladies cardiovasculaires, rénales et des vaisseaux périphériques) était de 27,5% chez les diabétiques. Les concentrations sériques des triglycérides et des pré-bêta-lipoprotéines, ainsi que le rapport β/α étaient significativement plus élevées chez les diabétiques que chez les sujets normaux et nettement supérieures chez les diabétiques avec vasculopathie que chez ceux sans vasculopathie. La lipoprotéin-lipase ne montrait aucune altération dans les deux groupes de patients diabétiques. La durée du diabète, le type de traitement et le degré de contrôle métabolique ne jouaient pas un rôle important dans l'étiologie des vasculopathies. D'après les résultats obtenus, l'hyper-pré-bêta-lipoprotéinémie semble être le résultat d'un trouble lipidique primitif; elle n'est pas glucido-dépendante et ne s'accompagne pas d'activité lipoprotéin-lipasique post-héparinique.
    Abstract: Resumen Ochenta enfermos de diabetes y 20 individuos normales de edad inferior a los 40 años han sido sometidos, en elAll-India Institute of Medical Sciences Hospital, New Delhi, ascreening para determinar la presencia de vasculopatias; también se han llevado a cabo investigaciones para determinar posibles relaciones con los triglicéridos, las pre-beta-lipoproteínas y la lipoprotein-lipasa del suero. La frecuencia de las vasculopatias (hipertensión, retinopatia, enfermedades cardiovasculares, renales y de los vasos periféricos) en los individuos diabéticos fué del 27,5%. Los niveles de los triglicéridos y de las pre-beta-lipoproteínas del suero y la relación β/α, eran significativamente más altos en los diabéticos que en los individuos normales y netamente superiores en los diabéticos vasculopáticos que en los que no presentaban indicios de la enfermedad. La lipoprotein-lipasa no presentaba alteraciones en ninguno de los dos grupos de pacientes diabéticos. La duración de la diabetes, el tipo de tratamiento y el grado de regulación metabólica no jugaban un papel importante en la etiología de las vasculopatias. Considerando los resultados objeto del presente estudio, la hiper-pre-beta-lipoproteinemia parece derivar de una primitiva alteración de los lípidos, no consecuencia de los carbohidratos o asociada con la actividad lipoprotein-lipasa post-héparinica.
    Notes: Riassunto Ottanta pazienti diabetici e 20 soggetti normali di età inferiore a 40 anni, dell'All-India Institute of Medical Sciences Hospital, New Delhi, sono stati sottoposti ascreening per accertare la presenza di vasculopatie; sono stati anche ricercati eventuali rapporti con i trigliceridi, le prebeta-lipoproteine e la lipoprotein-lipasi del siero. L'incidenza di vasculopatie (ipertensione, retinopatia, malattie cardiovascolari, renali e dei vasi periferici) è risultata, nei soggetti diabetici, pari al 27,5%. I livelli dei trigliceridi e delle pre-beta-lipoproteine del siero, nonché il rapporto β/α, erano significativamente più alti nei diabetici che nei soggetti normali e nettamente superiori nei diabetici vasculopatici che in quelli senza segni di vasculopatia. La lipoprotein-lipasi non si mostrava alterata in nessuno dei due gruppi di pazienti diabetici. La durata del diabete, il tipo di trattamento ed il grado di regolazione metabolica non avevano un ruolo importante nell'eziologia delle vasculopatie. Stando ai risultati ottenuti nel presente studio, l'iper-pre-beta-lipoproteinemia sembra essere dovuta ad un'alterazione lipidica primitiva; essa non è glucido-dipendente e non si accompagna ad attività lipoprotein-lipasica post-eparinica.

    Description / Table of Contents: Résumé Des nerfs sciatiques isolés de 21 rats albinois mâles atteints de diabète alloxane et de 6 animaux d'essai ont fait l'objet d'une étude au point de vue histopathologique après une période d'hyperglycémie durant 4 à 6 mois. Des animaux atteints du diabète, 9 n'avaient pas été traités avec insuline, tandis que les douze autres reçevaient une dose de 2,5 U/die de l'hormone. Dans les deux groupes, une légère dégénération myélenique se manifestait après le 4ème mois; au 5e–6e mois, le groupe des rats atteints de diabète n'ayant pas été traité avec insuline présentait une dégénération myélenique et du cylindraxe bien plus graves que dans le groupe des animaux traités. Les vaisseaux du sang intraneuraux étaient essentiellement normaux chez tous les animaux.
    Abstract: Resumen Se han estudiado desde el punto de vista histopatológico, tras un periodo de hiperglucemia de la duración de 4 a 6 meses, los nervios ciáticos aislados de 21 ratas blancas macho, afectas de diabetes de aloxina y de 6 animales de control. De los animales diabéticos 9 fueron tratados con insulina, mientras que los remanentes 12 recibiían una dosis de 2,5 unidades diarias del hormón. En ambos grupos, al 4° mes, se podía observar una leve degeneración mielínica; al 5°–6° mes, en el grupo de ratas diabéticass no tratadas con insulina, la degeneración mielínica y del cilindroeje era significativamente más grave que en los animales no tratados. Los vasos sanguíneos intraneurales esencialmente eran normales en todos los animales.
    Notes: Riassunto Nervi sciatici isolati da 21 ratti albini maschi con diabete da allossana e da 6 animali di controllo sono stati studiati dal punto di vista istopatologico dopo un periodo di iperglicemia della durata di 4–6 mesi. Degli animali diabetici, 9 non erano trattati con insulina, mentre i rimanenti 12 ricevevano una dose di 2,5 U/die dell'ormone. In entrambi i gruppi era presente, al 4° mese, lieve degenerazione mielinica; al 5°–6° mese, nel gruppo dei ratti diabetici non trattati con insulina la degenerazione mielinica e del cilindrasse era significativamente più grave che in quello degli animali trattati. I vasi sanguigni intraneurali erano essenzialmente normali in tutti gli animali.

    Notes: Abstract Pancreatic islet cell, thyroid, gastric parietal cell, and adrenal autoantibodies were studied in 110 young insulin-dependent diabetics (Type I; IDDM), 12 non-insulin-dependent diabetics (NIDDM), 26 patients with pancreatic diabetes, and 123 age- and sex-matched healthy controls. All the patients were aged 30 years or under at the onset of diabetes. Islet cell antibody was found in 31% of the patients with IDDM, but in only one patient with NIDDM, one patient with pancreatic diabetes, and one healthy control subject. Thyroid, parietal cell, and/or adrenal antibodies were present in 26% of the IDDM patients, 17% of the NIDDM patients, 12% of the patients with pancreatic diabetes, and 19% of the control subjects. There was no association between the presence of islet cell antibody and other organ-specific autoantibodies and any particular HLA phenotype. Data from the North Indian study have been compared with those from other populations of the world, similarities and differences have been brought out, and their significance has been discussed. The relative contribution of the autoimmune component in the etiopathogenesis of different forms of diabetes mellitus varies among the different populations of the world, accounting to some extent for the observed differences in incidence and clinical profiles.
