RESUMEN
Resumen El síndrome de Nicolau es una complicación infrecuente de la aplicación parenteral de diversos fármacos. Se caracteriza por la aparición de dolor, seguido de edema, eritema y luego una placa necrótica. Se reporta el caso de un hombre de 31 años que presenta este síndrome luego de la aplicación de penicilina benzatínica intramuscular. La biopsia apoyó el diagnóstico. Recibió tratamiento con enoxaparina y cilostazol con posterior mejoría.
Abstract Nicolau syndrome is a rare complication of the parenteral application of various drugs. It is char acterized by the appearance of pain, followed by edema, erythema, and then a necrotic plaque. We present the case of a 31-year-old male with this syndrome, after the application of intramuscular benzathine penicillin. The diagnosis was supported by the biopsy. He received treatment with enoxaparin and cilostazol with subsequent improvement.
RESUMEN
Análise de 32 casos de acidentes por injeção, na maioria das vezes, de substâncias oleosas no músculo deltoide. Os acidentes caracterizaram-se por dor e reações tróficas locais. Em muitos casos, simultaneamente, ocorreram distúrbios isquêmicos nas regiões escapular, peitoral e, especialmente, na extremidade do membro. Presume-se que esse complexo lesional é gerado: 1) pela ação lesiva do medicamento nas terminações nervosas, nos tecidos moles e perivasais; e/ou 2) pela entrada fortuita da substância no interior dos vasos, produzindo embolia e/ou endotelite trombosante; e/ou 3) pelo despertar de fenômenos vasomotores. As lesões da mão, geralmente, foram mais graves que as lesões deltoidianas, com a eventual perda de dedos, espontânea ou cirúrgica. Os diversos quadros clínicos do acidente foram semelhantes, mas algumas características lesionais permitiram identificar mecanismos fisiopatogênicos peculiares, o que tem significado conceitual e terapêutico.
Analysis of 32 cases of accidental injection of oily suspension (in most cases) into the deltoid muscle is reported. Pain and local ulcers characterized the accidents. In many cases, simultaneous ischemic disorders were observed in the scapular and pectoral regions and especially in the end of the upper limb. It is presumed that this complex lesion was caused by 1) the harmful action of the medication on nervous terminations, soft and perivascular tissues; and/or 2) occasional entrance of the substance into blood vessels, causing embolism and/or thrombotic endothelitis; and/or 3) vasomotor phenomena. Hand injuries were generally more severe than injuries in the deltoid region, with occasional spontaneous or surgical loss of fingers. Clinical statuses were similar, though some lesions had features, which allowed identification of peculiar physiopathogenic mechanisms, with conceptual and therapeutic significance.
