ABSTRACT
Background and Objective: During the course of the autoimmune thyroid diseases, ultrasonography change parallel to histopathology. Vitamin D is associated with autoimmune diseases and thus can affect thyroid blood flow. Our aim was to investigate the relationship between vitamin D insufficiency/deficiency and thyroid hemodynamic indices in patients with Hashimoto thyroiditis
Methods: A total of 93 patients who presented to Sakarya University Endocrinology outpatient clinic from April to September 2016 and diagnosed with Hashimoto thyroiditis were included in this study. Clinical and serologic data, thyroid antibodies and 25[OH] D3 were evaluated. Mean peak systolic velocity [mPSV], mean end-diastolic velocity [EDV], mean resistive index [RI] flows of superior and inferior thyroid arteries were measured with B-mode Doppler ultrasonography
Results: Vitamin D insufficiency/deficiency was detected in 59 [63.4%]. TPO Ab and TgAb levels were found higher in patients with vitamin D insufficiency/deficiency. In the normal vitamin D group, superior thyroid artery mPSV [32.21+/-6.73cm/s] and EDV[13.27+/-2.80 cm/s] were higher than in the low vitamin D group [mPSV [28.32+/-8.99cm/s] and EDV[10.67+/-3.68 cm/s]] [P=0.034, P=0.001, respectively]. Inferior thyroid artery EDV value was higher in the normal compared to the low vitamin D group [0.032]. RI measured in all arteries were higher in the vitamin D insufficient/deficient group compared to the Vitamin D normal group [p=0.001]
Conclusion: Vitamin-D insufficiency/deficiency has led to reduced parenchymal blood supply and increased micro-vascular resistance in Hashimoto thyroiditis patients
ABSTRACT
Hydrophilic guide wire-associated renal subcapsular hematoma [RSH] during patent ductus arteriosus [PDA] closure is an extremely rare clinical condition. Herein, we present the case of a 16-year-old adolescent who suffered accidental hydrophilic 0.035-inch guide wire-related RSH during PDA closure. This RSH was diagnosed by computerized tomography and selective renal angiography. It was successfully treated by conservative treatment
