ABSTRACT Objective Thyroid hormones have both direct and indirect effects on thermogenesis such as modulating vascular smooth muscle cell proliferation. However, the influence of more subtle changes in thyroid hormones on coronary atherosclerosis remains a matter of speculation. Smooth muscle cells play a crucial role in the pathogenesis of in-stent restenosis (ISR). However, the relationship between free thyroxine (fT4) and ISR has not been studied. In the present study, we aimed to assess the role of preprocedural serum fT4 level on the development of ISR in patients undergoing coronary bare metal stent (BMS) implantation. Materials and methods We enrolled and analyzed clinical, biochemical, and angiographic data from 705 consecutive patients without a history of primary thyroid disease [mean age 60.3 ± 9.3 years, 505 (72%) male]; all patients had undergone BMS implantation and further control coronary angiography owing to stable or unstable angina pectoris. Patients were divided into 3 tertiles based on preprocedural serum fT4 levels. Results ISR was observed in 53 (23%) patients in the lowest tertile, 82 (35%) patients in the second tertile, and 107 (46%) patients in the highest fT4 tertile (p < 0.001). Using multiple logistic regression analysis, five characteristics emerged as independent predictors of ISR: diabetes mellitus, smoking, HDL-cholesterol, stent length, and preprocedural serum fT4 level. In receiver operating characteristics curve analysis, fT4 level > 1.23 mg/dL had 70% sensitivity and 73% specificity (AUC: 0.75, p < 0.001) in predicting ISR. Conclusion Higher preprocedural serum fT4 is a powerful and independent predictor of BMS restenosis in patients with stable and unstable angina pectoris.

Neonatal adrenal hemorrhage is uncommon. It is present in 0,2% of newborns. Ten percent of the cases occur bilaterally. It can be associated with birth trauma, large birth weight, or neonatal course complicated by hypoxia and asphyxia, hypotension, or coagulopathy. Scrotal hematoma is an extremely rare manifestation of NAH. Most patients present scrotal swelling with bluish discolouration. Scrotal swelling with/without bluish discoloration in newborns may result from different causes. We report an unusual case of neonatal adrenal hemorrage secondary to perinatal asphyxia, associated with SH. Neonatal adrenal hemorrhage and scrotal hematoma were diagnosedby ultrasonography and treated by conservative treatment, avoiding unnecessary surgical exploration.

La hemorragia suprarrenal neonatal es poco frecuente. Se presenta en el 0,2% de los recién nacidos. El 10% de los casos son bilaterales. Puede estar asociada a un traumatismo al nacimiento, peso alto al nacer o un curso neonatal complicado por hipoxia, asfixia, hipotensión o coagulopatía. El hematoma escrotal es una manifestación extremadamente rara de la hemorragia suprarrenal neonatal. La mayoría de los pacientes presentan tumefacción escrotal con coloración azulada. En los recién nacidos, la tumefacción escrotal, con o sin coloración azulada, puede deberse a diferentes causas. Comunicamos un caso inusual de hemorragia suprarrenal neonatal secundaria a asfixia perinatal, que se manifestó con un hematoma escrotal. El diagnóstico de hemorragia suprarrenal neonatal y hematoma escrotal fue ecográfico; el tratamiento conservador evitó la exploración quirúrgica innecesaria.
