Blood Pressure Monitoring | Year: 2014

OBJECTIVE: The aim of this study was to validate the iHealth BP7 wireless wrist blood pressure monitor according to the European Society of Hypertension International Protocol (ESH-IP) revision 2010. MATERIALS AND METHODS: A total of 99 pairs of test device and reference blood pressure measurements (three pairs for each of the 33 participants) were obtained for validation. The ESH-IP revision 2010 for the validation of blood pressure measuring devices in adults was followed precisely. RESULTS: The device produced 66, 87, and 97 measurements within 5, 10, and 15 mmHg for systolic blood pressure (SBP) and 72, 93, and 99 mmHg for diastolic blood pressure (DBP), respectively. The mean±SD device-observer difference was -0.7±6.9 mmHg for SBP and -1.0±5.1 mmHg for DBP. The number of participants with two or three device-observer differences within 5 mmHg was 25 for SBP and 26 for DBP; furthermore, there were three participants for SBP and one participant for DBP, with none of the device-observer differences within 5 mmHg. CONCLUSION: On the basis of the validation results, the iHealth BP7 wireless wrist blood pressure monitor can be recommended for self-measurement in an adult population. © 2014 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Aim The purpose of the present study was to summarize the computed tomography (CT) features of renal carcinomas associated with Xp11.2 translocations, and determine whether the diagnosis can be reliably deduced from imaging findings. Materials and methods Radiological studies of six patients (aged from 9-29 years) with renal carcinoma associated with Xp11.2 translocations were retrospectively analysed. Results The tumours varied in size from 3.3-11 cm (mean 5.4 cm). Unenhanced CT and cortical, medullary, and pelvic-phase contrast-enhanced CT imaging was undertaken in all cases. Unenhanced CT revealed that tumours had a relatively increased radiodensity (4/6, ranged from 45-60 HU) and suggested the possibility of diffuse haemorrhage. Three of the six cases showed irregular and boundary calcification of the lesion. Contrast-enhanced CT showed relatively well demarcated tumours with heterogeneous enhancement (6/6). Prolonged enhancement of tumours might be a common sign (6/6) in Xp11.2 translocations. Three out of the six cases were combined with retroperitoneal lymph nodes metastasis. Conclusion Renal carcinomas associated with Xp11.2 translocations should be considered, particularly in children and young patients, when the lesion has calcification and is hyper-dense on unenhanced CT, and has prolonged enhancement on contrast-enhanced images. © 2013 The Royal College of Radiologists.

Cardiac rupture is a complication of myocardial infarction (MI) with extremely high mortality. Poor prognosis is usually predicted in conservatively treated patients. The treatment for cardiac rupture and thrombosis is in conflict. We reported an MI case of cardiac rupture and cerebral thrombosis using a conservative method. This case indicated that (1) It is noteworthy that patients suffering from the subacute form of rupture may remain haemodynamically stable. This type of patients may benefit from a conservative treatment without anticoagulation or antiplatelet at the onset of cardiac rupture. (2) Thirty days following cardiac rupture, it is safe to use warfarin anticoagulation for cerebral thrombosis treatment. The patient suffered from acute MI, cardiac rupture and subsequently cerebral thrombosis. We treated this patient in a conservative manner and the patient remained alive for 8 years. This case suggested that it may be safe to use warfarin anticoagulation treatment for cerebral thrombosis 30 days following cardiac rupture.

A 46-year-old male was diagnosed of lung adenocarcinoma with right adrenal gland metastasis in January 2009, and underwent chemotherapy (DC (docetaxel and cisplatin) regimen) and stereotactic radiotherapy. In December 2009, whole brain radiotherapy was given to the patient due to brain metastasis. In January 2010, he complained of redness, swelling and tenderness of the fifth terminal phalange of his right hand. Open surgery and biopsy confirmed bone metastasis to the finger. The patient then received local injection of OK-432 combined with radiotherapy. The symptoms were greatly relieved after treatment and the patient has survived for 28 months at the time of this report.

Objective The major atrial ganglionated plexi (GP) can initiate atrial fibrillation alone without any contribution from the extrinsic cardiac nervous system. However, if stimulation of the ventricular GP, especially the aortic root GP, can provoke atrial fibrillation (AF) alone is unknown. Our study was designed to investigate the independent role of aortic root GP activity in the initiation of AF. Methods In 10 Langendorff-perfused canine hearts, the atrial effective refractory period, pulmonary vein effective refractory period, and percentage of AF induced were measured at baseline and during aortic root GP stimulation. Results Stimulation of the aortic root GP shortened the atrial effective refractory period from 128 ± 10 ms at baseline to 103 ± 15 ms (P <.05) and shortened the pulmonary vein effective refractory period from 139 ± 14 ms to 114 ± 15 ms (P <.05). Furthermore, the percentage of AF induced in the 10 isolated hearts increased from 10% at baseline to 90% during aortic root GP stimulation (P <.05). Conclusions In Langendorff-perfused canine hearts, stimulation of the aortic root GP provokes AF in the absence of any extrinsic cardiac nerve activity. The aortic root GP is an important element in the intrinsic neuronal loop that can increase the risk of AF in isolated heart models. © 2014 by The American Association for Thoracic Surgery.
