Arterioesclerosis de Monckeberg en vasos uterinos: un interesante hallazgo incidental / Arteriosclerose de Monckeberg nos vasos uterinos: um achado incidental interessante / Monckeberg arteriosclerosis in uterine vessels: an interesting incidental finding

Se realizó la comunicación de un caso clínico-patológico, diagnosticado en el Hospital Docente Clínico Quirúrgico "Joaquín Albarrán" de La Habana. En dicha entidad se presentó en una paciente femenina de 85 años de edad con antecedentes de diabetes mellitus tipo 2, ingresada por cuadro de insuficiencia arterial de miembro inferior izquierdo por lo cual se le realizan amputación supracondilia y al tercer día de su estadía hospitalaria, fallece. En la autopsia se arribó al diagnóstico anatomopatológico de arterioesclerosis de Mönckeberg de vasos del útero. Esta es una forma de arterioesclerosis muy relacionada con la senectud, pero factores de riesgo como diabetes mellitus y la enfermedad renal crónica pueden contribuir de forma directa en su desarrollo y progresión. Su diagnóstico es un hallazgo incidental en muestras histopatológicas(AU)

A clinical-pathological case was reported, diagnosed at the Joaquín Albarrán Clinical Surgical Teaching Hospital in Havana. In this entity, an 85-year-old female patient with a history of type 2 diabetes mellitus was presented, admitted due to arterial insufficiency of the lower left limb, for which she underwent supracondylar amputation and died on the third day of her hospital stay. At the autopsy, the pathological diagnosis of Mönckeberg arteriosclerosis of vessels of the uterus was reached. This is a form of arteriosclerosis closely related to old age, but risk factors such as diabetes mellitus and chronic kidney disease can directly contribute to its development and progression. Its diagnosis is an incidental finding in histopathological samples(AU)

Um caso clínico-patológico foi relatado, diagnosticado no Hospital de Clínica Cirúrgica "Joaquín Albarrán" em Havana. Nessa entidade, apresentou-se uma paciente de 85 anos, com história de diabetes mellitus tipo 2, internada por insuficiência arterial do membro inferior esquerdo, para a qual sofreu amputação aupracondiliana e faleceu no terceiro dia de internação. Na autopsia, o diagnóstico patológico da arteriosclerose de Mönckeberg de navios do útero foi conseguido. Essa é uma forma de arteriosclerose intimamente relacionada à velhice, mas fatores de risco como diabetes mellitus e doença renal crônica podem contribuir diretamente para seu desenvolvimento e progressão. Seu diagnóstico é um achado incidental em amostras histopatológicas(AU)

A rabbit model for ascending infection in pregnancy: intervention with indomethacin and delayed ampicillin-sulbactam therapy.

OBJECTIVE: In a modified pregnant rabbit model using intracervical inoculation of Escherichia coli we investigated the effects of administration of delayed antibiotics and indomethacin on outcomes. STUDY DESIGN: We inoculated 10(5) colony-forming units of Escherichia coli or saline solution bilaterally in the cervix of New Zealand White rabbits at 70% of gestation and assigned animals to ampicillin-sulbactam therapy beginning at 0, 4, 8, 12, and 16 hours after inoculation with Escherichia coli or to no antibiotic therapy. We alternated indomethacin pretreatment in rabbits receiving no antibiotic therapy and rabbits starting ampicillin-sulbactam 4 hours after inoculation. RESULTS: Compared with saline solution inoculated control animals, those inoculated with Escherichia coli (and given no antibiotic therapy) had significant increases in fetal loss, fever, bleeding at 24 hours, and positive cultures (100%, 92%, 76%, 98% versus 0%, respectively, all p < 0.01). In Escherichia coli-inoculated animals receiving no antibiotic therapy pretreatment with indomethacin significantly decreased bleeding and delivery within first 24 hours compared with those not treated with indomethacin (p < 0.05) but did not significantly improve fetal survival. Ampicillin-sulbactam treatment stated at 0, 4, 8, and 12 hours after inoculation resulted in improved fetal survival compared with the untreated group (100%, 56%, 50%, 50% versus 0%, respectively, all p < 0.05). Treatment initiated at 16 hours resulted in outcomes similar to Escherichia coli-inoculated animals receiving no antibiotic therapy. CONCLUSION: Intracervical Escherichia coli inoculation produced infection in the uterus and uniform pregnancy loss. Pretreatment with indomethacin did not result in improved fetal survival. Ampicillin-sulbactam therapy, initiated as long as 12 hours after Escherichia coli inoculation, resulted in significant improvement in fetal survival compared with antibiotic therapy. We believe this model mimics ascending infection in pregnancy more closely than do previous animal models.
