Abstract

Background
The aims of the present study were to validate the Physiological and Operative Severity Score for the enUmeration of Mortality adjusted for oesophagogastric surgery (O-POSSUM).

Methods
Data on patients who underwent potentially curative oesophagectomy in a tertiary referral centre for adenocarcinoma or squamous cell carcinoma of the oesophagus were analysed. The in-hospital mortality predicted by O-POSSUM was compared with the actual value by linear analysis.

Results
Twenty-four (3·6 per cent) of 663 patients died in hospital. The observed : predicted ratio for in-hospital mortality was 0·29. The model had a poor fit (P &lt; 0·001). The area under the receiver–operator characteristic curve was 0·60 (95 per cent confidence interval 0·47 to 0·72); P = 0·113). O-POSSUM score was not related to the severity of complications.

Conclusion
O-POSSUM overpredicted in-hospital mortality threefold and could not identify patients at higher risk of death. O-POSSUM needs substantial modification before it can be used for comparison of treatment outcomes between centres.

AbstractBackgroundThe detection of parathyroid adenomas by 99mTc-labelled hexakis 2-methoxyisobutyl isonitrile (sestamibi) scintigraphy is influenced by several factors, including tumour size and serum level of parathyroid hormone (PTH). This study examined the relationship between sestamibi accumulation and multidrug resistance (MDR)-related P-glycoprotein (P-gp) expression in a large series of surgically excised parathyroid tumours.MethodsSeventy-eight patients underwent dual-phase sestamibi imaging before parathyroidectomy. Expression of P-gp within tumour cells was assessed by immunohistochemistry. Tumour size was measured and the ellipsoid volume calculated. Scan results were analysed in relation to preoperative serum levels of calcium and PTH, P-gp expression and tumour volume.ResultsSixty-four of the 78 sestamibi scans were positive and 14 negative. Smaller adenomas (less than 0·5 cm3) were more likely to be sestamibi negative than larger lesions (P = 0·006). Ten of 14 adenomas with negative imaging showed strong P-gp membrane positivity and 45 of 64 lesions with a positive scan did not show P-gp membrane expression, indicating a significant association between high P-gp membrane immunoreactivity and negative sestamibi result (P = 0·006).ConclusionThese data suggest an association between P-gp membrane expression and false-negative sestamibi scan result. Inhibition of the P-gp transmembrane pump using MDR modulators may therefore improve the sensitivity of sestamibi scintigraphy.

Resting Chest Pain, Negative Treadmill Exercise Electrocardiogram, and Reverse Redistribution in Dipyridamole Myocardial Perfusion Scintigraphy Might be the Features of Coronary Artery Spasm
Authors: Xiang Ding‐Cheng , Yin Ji‐Lin , He Jian‐Xin , Gong Zhi‐Hua 
Published: October 2007

AbstractBackground:Coronary artery spasm usually attacks while at rest and the diagnosis depends on provoking tests which mostly are invasive, expensive and not practical. Previous investigations demonstrated that in most patients with coronary artery spasm, treadmill exercise electrocardiography (TEEC) did not induce any ischemic changes, and myocardial perfusion scintigraphy (MPS) showed reverse redistribution (RR).Hypothesis:Combination of resting chest pain, negative TEEC and RR might be a rational noninvasive set to predict coronary artery spasm.Methods:Patients with chest pain at rest, no significant coronary artery stenosis, and willing to undergo acetylcholine test were included. TEEC, dipyridamole and rest thallium‐201 MPS were performed before or after coronary angiography. The patients were divided into spasm and nonspasm groups by acetylcholine test. The clinical features and results of TEEC and MPS were compared between the spasm and nonspasm groups.Results:Acetylcholine test was performed in 92 patients and coronary artery spasm was successfully provoked in 68 patients. Positive TEEC was induced in only 4 patients in the spasm group. RR was present in totally 77 patients and 68 of them were from the spasm group. By a combination of resting chest pain, negative TEEC and RR to diagnose coronary artery spasm, the sensitivity and specificity were 94% and 96% respectively.Conclusion:Combination of resting chest pain, negative TEE and RR appears to be a rational noninvasive set to predict coronary artery spasm.

Published: October 2007

AbstractObjective:To investigate the efficiency and safety of transcatheter interventional therapy for compound congenital cardiovascular abnormalities.Methods:From Nov 2001 to Jun 2006, a total of 36 patients (17 male, 19 female), aged 17.20 ± 10.52, with compound congenital cardiovascular abnormalities underwent transcatheter interventional procedure. These patients included 11 with perimembranous ventricular septal defect (PVSD) and patent ductus arteriosus (PDA), 8 patients with PVSD and atrial septal defect (ASD), 8 patients with ASD and PDA, 7 patients with ASD and pulmonary stenosis (PS), 1 patient with ASD and mitral stenosis(MS), 1 patient with coarctation of aorta (COA) and PDA. According to the principle of “easy first, hard second,” balloon valvuloplasties of PS or MS were performed before the closure of PVSD, and of PDA and ASD. Electrocardiogram and transthoracic echocardiogram were examined at 4 days, 1, 2, 6 and 12 months, respectively, after each procedure.Results:Transcatheter interventional therapy for compound congenital cardiovascular abnormalities was successful in all patients. Among these, 2 occluders were planted in each of 27 patients, 7 patients with ASD combined with PS and 1 patient with ASD combined with MS underwent successfully performed balloon valvuloplasty and ASD closure, 1 patient with COA combined with PDA underwent successfully performed balloon valvuloplasty and subsequent covered stent implantation. No patient encountered serious adverse events during the (30.5 ± 14.6) months of follow‐up.Conclusions:Transcatheter interventional therapy for compound congenital cardiovascular abnormalities could obtain satisfactory results with technical feasibility.
