Fei et al.: Safety and accuracy of intracavitary electrocardiography and ultrasound in breast cancer patientsThis study aims to explore the safety and accuracy of the intracavitary electrocardiography and ultrasound in the peripherally inserted central venous catheter tip positioning of breast cancer patients. A total of 176 breast cancer patients who were treated in the breast surgery department of our hospital from January 2018 to January 2019 were selected. They were randomly divided into the Electrocardiogram-UI group (n=88) and the control group (n=88). In the Electrocardiogram-UI group, the peripherally inserted central venous catheter tip positioning was under the guidance of the bedside Electrocardiogram combined with ultrasound, while the peripherally inserted central venous catheter insertion in the control group was performed by the traditional technology. The accuracy of peripherally inserted central venous catheter tip positioning, psychological state, anxiety, pain degree, and complications were compared between the two groups after surgery. The results showed that the positioning accuracy rate of the catheter tip in the Electrocardiogram-UI group was 99.40 %, while that in the control group was 92.10 %. In the control group, the accuracy rate of the catheter tip positioning in the 6th, 7th and 8th ribs was 20.30 %, 64.10 %, and 14.70 % respectively, while that in the Electrocardiogram-UI group was 32.20 %, 40.30 % and 19.60 % respectively, with a significant difference between the two groups. And 24 h before the catheter insertion, there was no significant difference in the anxiety scores between the two groups. However, 24 h after the catheter insertion, the anxiety and pain scores in the Electrocardiogram-UI group were significantly lower than that of the control group. In terms of the complications, in the first w, two patients in the Electrocardiogram-UI group had thrombosis, while four patients in the control group. No patients had the symptoms of the chest discomfort, arrhythmia, or infection in both groups. At the end of three and six mo, the incidence of thrombosis in the Electrocardiogram-UI group was significantly lower than that of the control group. The peripherally inserted central venous catheter tip positioning technology guided by Electrocardiogram combined with ultrasound is an ideal method for peripherally inserted central venous catheter insertion. It can improve the quality of life of the breast cancer patients and promote the prognosis of the breast cancer patients.
Background The choroid is the most common site for intraocular tumor metastasis because of its abundant vascular supply. However, choroidal metastasis in penile cancer is highly unusual. Here, we report the first case of diagnosis of choroidal metastasis at presentation in a patient with penile squamous cell carcinoma. Case presentation A 43-year-old Asian man with a 3-year history of penile cancer presented with metastasis in the right intraocular sites. Magnetic resonance imaging showed hyperintensity in the T1-weighted images and hypointensity in the T2-weighted images of the right eye. After enucleation of his right eye, histopathological analysis led to a diagnosis of metastatic, moderately differentiated penile squamous cell carcinoma. Conclusions Penile cancer typically occurs as penile squamous cell carcinoma, and its most common metastatic sites are the inguinal lymph nodes. Hemorrhagic transfer of tumor cells is extremely rare, especially to intraocular sites. Intraocular metastatic tumors have a unique presentation on imaging, as observed on magnetic resonance imaging and histopathological analysis. This novel finding of intraocular metastasis in penile squamous cell carcinoma is of great significance to optic surgeons and oncologists as it has new implications in the diagnosis of and timely intervention for penile cancer metastasis.
