Juxtaglomerular cell tumors (JGCTs) or reninoma are rare kidney tumors leading to secondary hypertension, and the non-specific clinical manifestations bring about challenges to the diagnosis. This study is to summarize the clinical features, laboratory findings, and treatment of JGCTs. The PubMed, EMBASE database, and manual search were utilized to find all cases, and 158 reports containing 261 patients were identified. Data on patients' demographics, clinical features, diagnostic methods, and treatment options were collected and analyzed. JGCTs occurred predominantly in female patients (female to male ratio, 2.1:1). The median age of patients was 25 years (IQR:18-34 years). Hypertension (97.24%) was the cardinal manifestation. Hypokalemia was reported in 78.71% (159/202) of subjects, and normal serum potassium accounted for 20.79% (42/202). In cases with assessed plasma renin activity (PRA) levels, the median PRA was 7.89 times the upper limit of normal (IQR:3.58-14.41), and 3.82% (5/131) of cases in the normal range. Tumors were detected in 97.8% (175/179) computed tomography (CT), 94.7% (72/76) magnetic resonance imaging (MRI), and 81.5% (110/135) ultrasound, respectively. For 250/261 patients undergoing surgical procedures, 89.14% (197/221), 94.94% (150/158), and 100% (131/131) of patients were restored to normal blood pressure, PRA, and serum potassium, respectively. JGCTs are commonly associated with hypertension, hypokalemia, and hyperreninemia, whereas patients with normotension, normokalemia, and PRA should be systematically pursued after drug-elution lasting for 2 weeks. CT and MRI are more sensitive imaging diagnostic methods. The blood pressure and biochemical parameters of most patients returned to normal after surgery.

Background:The adverse effects of anticancer therapy in patients with malignancies and cardiovascular diseases are complicated. Oxaliplatin is one of the most commonly used chemotherapy drugs for gastric and colorectal cancers, and oxaliplatin-induced cardiotoxicity has rarely been reported.Case Summary:We report a 76-year-old man with adenocarcinoma of the esophagogastric junction and a 40-day history of non-ST-elevation myocardial infarction who exhibited a new third-degree atrioventricular block after oxaliplatin administration. We immediately withdrew oxaliplatin treatment and, to avoid future episodes, we implanted a permanent pacemaker for safety and added diltiazem hydrochloride. The third-degree atrioventricular block disappeared after oxaliplatin withdrawal. We detected no recurrence of the third-degree atrioventricular block in future chemotherapies.Conclusions:This is the first reported oxaliplatin-induced third-degree atrioventricular block, likely mediated by coronary artery spasm. Cancer patients with acute coronary syndrome are a unique and vulnerable population, whom physicians should carefully evaluate and monitor during anticancer treatment. Remarkably, even the most common chemotherapy drugs can cause life-threatening cardiac adverse events.

Background:Subclavian artery stenosis (SAS) is a peripheral arterial disease of asymptomatic appearance and disastrous consequences. The traditional screening method remains unsatisfactory.Objective:The study aimed to assess the diagnostic performances of inter-arm systolic pressure difference (IASBPD), derivatives of pulse volume recording (PVR), and their combination in detecting subclavian artery stenosis.Materials and methods:The present study was a retrospective analysis of clinical data from inpatients suspected of supra-arch artery stenosis in Fuwai hospital during 1 year, who underwent selective arterial angiographies. We obtained simultaneous blood pressure measurements on four limbs and pulse waves for calculating IASBPD and PVR derivatives prior to the angiographies. We utilized the receiver operating characteristic curve (ROC) to calculate the optimal cut-off value of IASBPD, upstroke time (UT), and upstroke time per cardiac cycle (UTCC) for detecting SAS. Moreover, we compared the sensitivity and specificity of IASBPD, UT, UTCC, and their combinations for diagnosing SAS (Clinical trial number: NCT03521739).Results:We consecutively enrolled 320 eligible patients. Based on SAS's definition of stenosis above 50%, the area under the curve of IASBPD, UT, and UTCC were 0.84, 0.76, and 0.80 (P < 0.001). And their corresponding cut-off points were 9 mmHg, 202 milliseconds, and 23.2%. The sensitivity and specificity of IASBPD ≥ 9 mmHg were 57.0 and 94.1%. UT ≥ 202 ms and UTCC ≥ 23.2% yielded similar sensitivity (72.6 vs. 72.6%, P > 0.05), but UTCC had higher specificity (81.1 vs. 72.4%, P < 0.05). The sensitivity of the combination of IASBPD and UT (85.2%) or UTCC (78.5%) was significantly higher than IASBPD alone (57%, P < 0.05). The specificity of either combination decreased to 67.6 and 76.8% (P < 0.05).Conclusions:This present study showed that the combinations of IASBPD and PVR-derived parameters promoted diagnostic sensitivity and preserved adequate specificity than those alone for detecting SAS.

BACKGROUND:Coronary artery-to-pulmonary artery fistula is a rare disorder characterized by abnormal vascular communication between the coronary artery and pulmonary artery. While most patients remain asymptomatic, some might exhibit symptoms of myocardial ischemia, congestive heart failure, or even sudden cardiac death if coronary aneurysm, thrombosis, infective carditis, or other congenital cardiac defects coexist. Case presentation We present a 66-year-old male complaining of angina pectoris with a history of hypertension and active smoking. He was diagnosed with a coronary aneurysm based on coronary computed tomography angiography. We subsequently identified a coronary artery-to-pulmonary artery fistula with giant aneurysmal dilation on coronary angiography. Ultimately we conducted surgery ligation and aneurysmorrhaphy. During surgery, we discovered newly formed thrombus within the aneurysmal cavity. Histological analysis of the aneurysmal wall supported the diagnosis of the congenital disorder. Our patient was successfully discharged and remained asymptomatic at two months of follow-up.CONCLUSION:We presented a rare and complex combination of congenital coronary artery-to pulmonary artery fistula, giant coronary aneurysmal dilatation, and thrombosis through multi-modality evaluations.

BACKGROUND:Both acute myocardial infarction and acute pulmonary embolism are distinct medical urgencies while they may conincide. Leriche's syndrome is a relatively rare aortoiliac occlusive disease characterized by claudication, decreased femoral pulses, and impotence. We present the first case of concomitant acute pulmonary embolism, acute myocardial infarction, and Leriche syndrome.CASE PRESENTATION:A 56-year-old male with a history of intermittent claudication was admitted for evaluating the sudden onset of chest pain. Elevated serum troponin level, sustained high D-dimer level, ST-T wave changes on electrocardiogram, and segmental wall motion abnormality of the left ventricle on transthoracic echocardiography were noted. Pulmonary Computed Tomography Angiogram revealed multiple acute emboli. Aortic Computed Tomography Angiogram spotted complete obstructions of the subrenal aorta and bilateral common iliac arteries with collateral circulation, maintaining the vascularization of internal and external iliac arteries. We stated the diagnosis of acute pulmonary embolism and Leriche syndrome and initiated oral anticoagulation. However, Q waves on electrocardiogram and wall motion abnormality on echocardiography persisted after embolus dissolved successfully. Coronary computed tomography angiogram found coronary arterial plaques while myocardial Positron Emission Tomography detected decreased viable myocardium of the left ventricle. We subsequently ratified the diagnosis of concurrent acute pulmonary embolism, acute myocardial infarction, and Leriche syndrome. The patient was discharged and has been followed up at our center.CONCLUSION:We described the first concurrence of acute pulmonary embolism, acute myocardial infarction, and Leriche syndrome.

Fibromuscular dysplasia (FMD) is a nonatherosclerotic, noninflammatory arterial disease, commonly involving the renal arteries. Here we report a case of a 16-year-old Chinese male who was found to have severe hypertension with proteinuria for 2 years. Computed tomography showed absence of the left kidney and enlargement of the right kidney. Subsequent angiography confirmed the above findings and revealed narrowing of both the upper and lower branches of the right renal artery caused by FMD. These combined lesions are very rare, and individuals affected are at increased risk of renal dysfunction if left untreated. Treatment with percutaneous balloon angioplasty is the first choice in such a patient and usually results in optimal outcomes.
