    Description / Table of Contents: Résumé Des échantillons de sérum de 16 victimes de traumatisme et de 31 opérés ont été prélevés pour déterminer les taux et l'activation du C3. Il fut constaté immédíatement après le traumatisme ou l'opération une activation et une chute des niveaux de C3. L'intensité de la déplétion fut en relation directe avec l'importance de l'agression (déterminée par le test de la gravité du traumatisme: ISS), et l'importance de l'intervention appréciée en fonction de la durée de l'opération et de la perte de sang. La moyenne du test ISS chez les sujets dont le complément était activé fut de 20.3 alors qu'elle fut de 6.6 (p}〈0.01) quand il n'était pas activé. Le taux moyen de complément sérique fut de 80.3 mg% quand le test était égal ou supérieur à 12 alors qu'il fut de 110.2 mg% (p}〈0.01) quand il n'était pas activé. Le dosage des taux de C3 sérique à intervalle de 24 heures démontra un retour progressif à la normale après plusieurs jours dans les cas non compliqués. Au contraire l'absence de normalisation témoigne de l'existence d'une complication en particulier d'un foyer septique occulte qui fut recherché et découvert ou qui se manifesta de lui-mÊme pendant la période d'observation. Le traitement chirurgical de ce foyer entraÎna un retour rapide à un taux normal du C3 sérique. Chez un patient qui succomba à l'infection ce taux resta invariablement bas. La détermination du taux de C3 à intervalles réguliers est donc à recommander car elle constitue une méthode d'appréciation de la gravité d'un traumatisme ou d'une intervention et permet de diriger le traitement en fontion de ses données.
    Abstract: Resumen Muestras de suero de pacientes traumatizados (16) y operados (31) fueron analizadas para determinar los niveles y activación de C3. Se encontró en los períodos postraumáticos y postoperatorios inmedíatos la activación de C3 con un descenso en su nivel de concentración sérica. El grado de depleción sérica de C3 apareció directamente relacionado con la gravedad de la lesión, segÚn el índice de severidad de la injuria (ISS), y con la magnitud del procedimiento quirÚrgico efectuado, segÚn su duración y la pérdida total de sangre. El ISS promedio de los pacientes con activación del complemento fue de 20.3, en comparaciÔn con el ISS de los pacientes que no exhibieron activación del complemento (ISS promedio, 6.6;p}〈0.01). El nivel promedio de C3 de los pacientes con ISS ≥ 12 fue 80.3 mg%, en comparaciÔn con el nivel promedio de 110.2 mg% en pacientes con ISS 〈12 (p〈0.01). La determinación seriada de los niveles séricos de C3 a intervalos de 24 horas en casos no complicados reveló un retorno gradual a niveles casi normales en un plazo de varios días. El no retorno a nivelés normales en el plazo esperado fue invariablemente indicativo de complicaciones y en la totalidad de los casos se evidenció un foco séptico. La resolución de la complicación séptica medíante intervención terapéutica dió lugar a un pronto retorno a nivelés normales. Un paciente que finalmente sucumbió por sepsis mantuvo bajos nivelés de C3 hasta el final. Se recomienda la determinación seriada del nivel sérico de C3 como un parámetro efectivo y económico de predicción de complicaciones sépticas en pacientes traumatizados y operados.
    Notes: Abstract Serum samples of traumatized (16) and operated (31) patients were analyzed to determine C3 levels and activation. It was found that in the immediate postinjury and postoperative periods, serum C3 activation occurred with a fall in C3 levels. The degree of serum C3 depletion was directly related to the severity of injury, as assessed by the injury severity score (ISS), and to the extent of surgical procedure performed, as assessed by the total duration of surgery and total blood loss. The mean ISS of patients with activated complement was 20.3, in comparison with the ISS of those in whom complement was not activated (mean ISS, 6.6; p〈0.01). The mean serum C3 level of patients with ISS≥12 was 80.3 mg% in comparison with the mean C3 level (110.2 mg%) of those with ISS〈12(p 〈0.01). Serial assay for serum C3 levels at 24-hour intervals in uncomplicated cases revealed a gradual return of the levels to near normal values over a period of several days. Failure to return to normal levels at the expected time invariably indicated complications and, in all such patients, an occult septic focus was either discovered or it revealed itself during the subsequent period of observation. Resolution of septic complication by therapeutic intervention led to a prompt return of the levels to normal. One patient ultimately succumbed to sepsis and had persistently low C3 levels until death. Serial serum C3 estimation is recommended here as a simple, effective, and inexpensive parameter for feedback information in the management of traumatized and operated patients.

    Notes: Abstract A retrospective analysis of 66 cases of thyroid cancer presenting as a solitary thyroid nodule (STN) from an endemic area is presented herein. The workup included TSH estimation and radionuclide scanning and patients were divided into two groups. Group A included cases of STN carcinoma diagnosed histologically in patients clinically presenting as a benign STN. Of all the patients who presented with a benign STN, malignancy was found more frequently in ‘cold’ nodules (13.5 per cent), than in nodules with a different presentation on scintiscanning (0–9.5 per cent). Cancers occurred in 5 per cent of the females and in 19.5 per cent of the males. Group B included patients with overt signs of malignancy. In both groups, the clinical behaviour was determined by the stage at presentation according to TNM classification. TNM staging was found to be a good prognostic indicator, comparable to histopathology. Thus, locoregional recurrence and mortality were found to be higher in advanced T3 lesions and in Group B patients. On the basis of these findings it is suggested that STN cancers may either be an earlier stage of the disease or that the STN cancers in the two groups may be separate disease entities.

    Notes: Abstract A case of extramedullary plasmacytoma in the soft tissues of the posterior chest wall of an 80-year old man is reported herein. Immunofluorescence study showed that the tumor cells produced IgGλ. An M-component was also detected in the patient’s serum by paper electrophoresis. Two months following the open biopsy done to establish diagnosis, the tumor underwent spontaneous regression and the M-component in the serum also disappeared. This is the first case report of spontaneous regression of an extramedullary plasmacytoma and the probable reasons for this spontaneous regression are discussed herein.

    Notes: Ultrastructural changes in the efferent duct and in different regions of the epididymis in men with obstructive azoospermia were compared with corresponding tissues collected from men of proven fertility who underwent castration due to malignancy of the prostate. Major degenerative changes were seen in the efferent duct and the caput epididymidis of men with obstruction at the caput epididymidis which may have been induced by fluid pressure due to defective absorption of testicular fluid in the caput epididymidis. These degenerative changes included decrease in tubular and lumen diameter of the caput and the cauda epididymides, decrease in height of the stereocilia, reduction in-rough endoplasmic reticulum and Golgi material, and presence of lipofuscin and osmiophilic dense bodies. The degenerative changes were less when the site of obstruction was in the cauda epididymidis since fluid reabsorption would continue to take place normally in the caput epididymidis. In men who had undergone vasoepididymostomy (VEA), the ejaculated spermatozoa showed a high percentage of morphological abnormalities which may have occurred due to adverse effects of long-term obstruction on spermatogenesis. © 1993 Wiley-Liss Inc.
