Abstract
The retrograde response (RR) is a compensatory mechanism by which mutant strains of yeast are able to cope with mitochondrial DNA (mtDNA) impairments by up-regulating the expression of the stress-responder nuclear genes and significantly increasing lifespan. Starting from the observation that both mtDNA variability and Tyrosine hydroxylase (THO, stress-responder gene) variability are correlated with human longevity, we asked ourselves whether mechanisms similar to RR may exist in humans. As a first investigative step we have analyzed the distribution of the mtDNA inherited variants (haplogroups) according to THO genotypes in three sample groups of increasing ages (20-49 years; 50-80 years; centenarians). We found that the mtDNA haplogroups and the THO genotypes are associated randomly in the first group, while in the second group, and particularly in the centenarians, a non-random association is observed between the mtDNA and nuclear DNA variability. Moreover, in centenarians the U haplogroup is over-represented (p=0.012) in subjects carrying the THO genotype unfavorable to longevity. On the whole these findings are in line with the hypothesis that longevity requires particular interactions between mtDNA and nuclear DNA and do not exclude the possibility that an RR has been maintained throughout evolution and it is present in higher organisms.

Abstract
Although nitric oxide (NO) participates in development of hypersensitivity states in the spinal cord thought to underlie chronic pain, it also participates in analgesia produced by various drugs. In rats with a hypersensitivity state following peripheral nerve injury, spinal administration of an NO donor or l-cysteine alone produced no effect, whereas their combination, which yields s-nitroso-l-cysteine (SNC) powerfully reduced hypersensitivity. In the current study, we examined the ability of SNC to stimulate release of a known spinal analgesic neurotransmitter, norepinephrine (NE), as a possible mechanism of analgesic action of NO in the spinal cord. SNC (but not the NO donor alone or decomposed SNC) produced a concentration-dependent release of NE from rat spinal cord synaptosomes. The d-isomer of SNC was less potent than the l-isomer, and the effect of SNC was partially blocked by l-, but not d-leucine, implicating an interaction with the l-amino acid transporter. SNC-induced NE release was partially Na(+) dependent, but largely Ca(2+) independent. NE uptake inhibitors partially antagonized the effect of SNC, but guanylate cyclase inhibitors were without effect. These data are therefore consistent with NO stimulating NE release in the spinal cord via reaction with thiol containing compounds, such as cysteine, entry into NE terminals via active transport, and production of both exocytotic and carrier mediated release.

Abstract
OBJECTIVE To evaluate the accuracy of the Brugada algorithm for analysis of wide-complex tachycardia (WCT) when applied by board-certified emergency physicians and board-certified cardiologists. METHODS A database consisting of 157 electrocardiograms of WCTs were evaluated in a blinded fashion using the Brugada criteria to determine the presence of ventricular tachycardia (VT) or supraventricular tachycardia with aberrancy. These results were then compared with the electrophysiologically proven diagnosis for each tracing. Sensitivity and specificity of the Brugada criteria for diagnosis of VT were calculated. Two board-certified emergency physicians and two board-certified cardiologists analyzed each tracing, and interobserver agreement was determined using the kappa statistic. RESULTS Sensitivity and specificity for the determination of VT using the Brugada algorithm were 85% [95% confidence interval (95% CI) = 79% to 91%] and 60% (95% CI = 43% to 78%) for cardiologist 1 (C 1) and 91% (95% CI = 86% to 96%) and 55% (95% CI = 37% to 72%) for C 2. Emergency physician (EP 1) achieved a sensitivity of 83% (95% CI = 78% to 91%) and a specificity of 43% (95% CI = 25% to 59%), while EP 2 attained 79% (95% CI = 73% to 87%) and 70% (95% CI = 51% to 84%), respectively. The original authors achieved a sensitivity of 98.7% and specificity of 96.5% when determining VT in their study population. Interobserver agreement for the emergency physicians and the cardiologists in determining VT was 82% and 81%, respectively. CONCLUSIONS Neither the emergency physicians nor the cardiologists were able to achieve a sensitivity or specificity as high as that reported by the original investigators when using the Brugada algorithm to determine the presence of VT.

Abstract
The progressive use of information systems and information technology has the potential to transform the way complex organisations are managed and the way they operate. This article reports the findings of a study undertaken to examine the importance of various factors related to the progressive use of information technology in Australian hospitals. Our analysis of data from 84 hospitals shows that hospital size has a significant positive relationship with the progressive use of information technology, as does the chief executive officer's attitude to information technology; however chief executive officer participation in information technology activities does not. The implications of these findings for the role of top management are discussed.

Abstract
Nitric oxide has been shown to react under physiologic conditions with norepinephrine (NE) to produce 6-nitro-norepinephrine (6-NO(2)-NE), a compound that enhances NE release in the brain. Previous studies suggest that 6-NO(2)-NE is formed in the spinal cord and stimulates spinal NE release to produce analgesia. The purpose of the current studies was to examine the mechanisms by which 6-NO(2)-NE stimulates NE release in the spinal cord. Crude synaptosomes were prepared from spinal cords of male Sprague-Dawley rats and loaded with [(3)H]NE. Incubation of synaptosomes with 6-NO(2)-NE resulted in a release of NE, with a threshold of 1 microM 6-NO(2)-NE and a maximum effect of 30% fractional release. NE transporter inhibitors desipramine and nomifensine blocked NE release from 6-NO(2)-NE, and desipramine exhibited an IC(50) of 9.6 microM. NE release from 6-NO(2)-NE was dependent on external Na(+), but not Ca(2+) or the activity of guanylate cyclase. 6-NO(2)-NE also blocked uptake of [(3)H]NE into synaptosomes, with an IC(50) of 8.3 microM. These data are consistent with a direct action of 6-NO(2)-NE on noradrenergic terminals in the spinal cord to release NE. This action is independent of guanylate cyclase activation, and most likely shares a common mechanism with classic monoamine releasers such as amphetamine that cause direct release of NE from vesicles into the nerve terminal cytoplasm, leading to extracellular release by reverse transport.

Abstract
INTRODUCTION Abdominal actinomycosis is an uncommon disease. Nevertheless it should be considered in case of unclear tumor-like abdominal masses. METHODS We report a case of a 49-year-old patient with an intrauterine device. The patient was submitted with a solid and painful tumor in the upper abdomen. After sonography, computerized tomography, gastroduodenoscopy and colonoscopy the preoperative presumptive diagnosis was a carcinoma of the transvers colon invading the abdominal wall. Pathological examination after a right hemicolectomy surprisingly revealed an actinomycosis. RESULTS Based on this case diagnostic tools and therapeutic options of actinomycosis of the colon are discussed. CONCLUSIONS This case illustrates the importance to consider the possibility of actinomycosis when finding an unclear abdominal mass. After a surgical excision an abdominal actinomycosis requires antibiotic therapy.

Abstract
Epilepsy in childhood may alter family relationships but the relevance of these changes for the increased rates of psychopathology has been little investigated. This study uses maternal expressed emotion (EE) to examine family relationships of children with epilepsy and the association with high risk for psychiatric disorder. EE was assessed using the Camberwell Family Interview carried out with the mothers of 22 schoolchildren with chronic epilepsy who were attending a general hospital outpatient clinic. Sixteen of these children had similarly aged healthy siblings who served as controls. High risk for psychiatric disorder in the children and mothers was assessed using behavioural, mood, and self-esteem questionnaires completed by mothers, teachers, and children. It was found that mothers showed significantly more emotional overinvolvement and a trend for more hostility towards their children with epilepsy than towards sibling controls. For the 22 children with epilepsy, maternal emotional overinvolvement was not associated with child behavioural deviance. High levels of criticism and, to a lesser extent, hostility did show associations with child behavioural deviance, and the strongest links were between maternal criticism and maternal rated antisocial and overactive behaviour in the child. Fewer positive comments by mothers towards the children were associated with child emotional symptoms and lower self-esteem in a number of areas. This study suggests that further research could consider the appropriateness of psychological intervention for families in which mothers are critical and hostile and whose children show antisocial behaviour.

Abstract
Mitochondrial DNA (mtDNA) is characterized by high variability, maternal inheritance, and absence of recombination. Studies of human populations have revealed ancestral associated polymorphisms whose combination defines groups of mtDNA types (haplogroups) that are currently used to reconstruct human evolution lineages. We used such inherited mtDNA markers to compare mtDNA population pools between a sample of individuals selected for successful aging and longevity (212 subjects older than 100 years and in good clinical condition) and a sample of 275 younger individuals (median age 38 years) carefully matched as to sex and geographic origin (northern and southern Italy). All nine haplogroups that are typical of Europeans were found in both samples, but male centenarians emerged in northern Italy as a particular sample: 1) mtDNA haplogroup frequency distribution was different between centenarians and younger individuals (P=0.017 by permutation tests); and 2) the frequency of the J haplogroup was notably higher in centenarians than in younger individuals (P=0.0052 by Fisher exact test). Since haplogroups are defined on the basis of inherited variants, these data show that mtDNA inherited variability could play a role in successful aging and longevity.

Abstract
The development of meat-eating habits of 999 Australian children between 1 and 16 years of age stratified across socioeconomic groups, was determined using a 4-day diary and measurement procedures to document intake. The results indicated that a stable pattern of meat-eating behaviour, as regards the frequency and type of meat eaten was established during the period 1-4 years of age and remained until 10-12 years for males and until at least 14-16 years for females. In contrast, the amount of meat consumed increased with age, the greatest increases occurring with adolescent males who ate the largest amounts of beef, chicken and pork. It is suggested that the early establishment of meat-eating habits may reflect a more general effect that may occur with other types of food.

Abstract
The possibility that four loci (REN, THO, PARP, SOD2) are associated with longevity was explored by comparing the genotypic pools of subjects older than 100 years with those of younger subjects matched for sex and geographic area (northern and southern Italy). The markers (all located within the respective gene) were HUMREN4; HUMTHO1; HUMPARP (gt)845nt; SOD2(C/T)401nt. In order to reduce the number of genotypes, multiallelic polymorphisms were recoded as diallelic according to allele size and frequency patterns (small: S, and large: L, alleles). A significant loss of LL homozygous genotypes was found at the THO locus in male but not in female centenarians with respect to matched controls. On the other hand no significant difference was found between case/control genotypic frequencies at REN, PARP, SOD2 loci. The latter loci therefore do not affect inter-individual variability in life expectancy (at least in terms of qualitative variants associated with the tested markers). However, the data is consistent with an association between the THO locus and longevity.

Abstract
The associations between life events, mood, mental strain and cardiovascular risk factors were investigated in the Renault/Volvo Coeur Study. About 1,000 men, blue-collar and white-collar workers, were asked by means of interview-administered questionnaires about life events experienced during the year preceding the screening, about mood and mental strain and about smoking, alcohol consumption and exercise habits. Blood pressure, concentration of serum lipids and blood glucose, and anthropometric measures were determined in a screening procedure. Negative life events, especially work-related, were associated with depressed mood and mental strain but not with elevation of biological risk factors such as elevated blood pressure and serum lipids. Depressed mood and mental strain were related to increased tobacco consumption in blue-collar workers and increased alcohol consumption in white-collar workers.

Abstract
The analysis of seven different age cohorts (697 individuals from 10 to 109 years old) revealed age-related changes in the 3'APOB-VNTR genotype pool. By recoding the 3'APOB-VNTR alleles into three size-classes (small, S, 26-34 repeats; medium, M, 35-39 repeats; large, L, 41-55 repeats), an age-related convex trajectory of the frequency of SS homozygotes was found. The frequency of SS in the genotype pool increased from the group aged 10-19 years (3.06 +/- 1.74%) to that aged 40-49 years (8.51 +/- 4.07%). Then it declined reaching the minimum value in centenarians (1.58 +/- 0.90%). The observed trajectory is in agreement with that expected by assuming crossing of mortality curves relevant to subgroups of individuals having different genotypes.

Abstract
The relationship between protective buffering, a style of coping in which the individual hides his/her concerns from spouse, and level of distress was studied among post-myocardial infarction (MI) patients and their spouses. Forty-three male married MI survivors and their wives completed measures of psychological distress and protective buffering at 4 weeks and 6 months post-hospital discharge. At both time periods, a greater propensity for protective buffering by the patient was related to higher levels of patient distress. Protective buffering by wife was also associated with higher levels of wife distress. In addition, patient buffering at 4 weeks predicted increased patient distress at 6 months. The results suggest that male MI patients who conceal their worries from their spouses adjust more poorly over time.

Abstract
Although ultrasound is a highly useful tool for clinical diagnosis, it has certain limitations in accurately quantifying internal carotid stenosis or diagnosing internal carotid occlusion. However, these limitations can be overcome by increasing the echogenicity of flowing arterial blood by use of echo-enhancement agents. Two phase III studies assessed the usefulness of the IV transpulmonary echo enhancer Levovist (SH U 508A) in improving characterization and quantification of severe internal carotid stenosis on ultrasound scans. In addition, Levovist-induced enhancement characteristics of the Doppler frequency spectrum have been analyzed. To be included in the study reviewed here, patients had to have a high-grade (> or = 70%) stenosis or occlusion of an internal carotid artery (ICA), as judged by conventional angiography or by standard cervical Doppler ultrasound. Patients were excluded from consideration if they were pregnant or nursing, had a history of galactosemia, or had received an ionic contrast medium within 24 hours before or after the intended administration of Levovist. Written informed consent was obtained from all patients before entry into the study. Of 32 patients (14 women, 18 men, median age 64 yr) who were included in this study, high-grade stenosis was verified in 30 ICA vessels and occlusion was verified in two vessels. After admission into the study, the carotid bifurcation was insonated in all patients using a 7.5-MHz linear array transducer for color Doppler-assisted duplex imaging and a 4-MHz pulsed-wave Doppler for velocity spectrum measurements before and after injection of the echo enhancement agent Levovist. Levovist-induced increases in carotid blood echogenicity began 11 +/- 2 seconds (mean +/- SD) after the start of injection, peaked at 21 +/- 2 dB, and had a half-life of 75 seconds. A fast Fourier transform of the original Doppler velocity spectrum demonstrated Levovist-induced enhancement throughout the entire velocity spectrum, with an increase in ICA blood flow velocity paralleling an increase in reflected ultrasound energy. Quantitative vascular measurements (cross-sectional luminal area reduction and plaque length) obtained before and during echo enhancement were highly correlated (r > 0.90). However, visualization of the entire length of the intrastenotic residual flow lumen, was significantly improved by Levovist enhancement (52% versus 83%; p = 0.01). Levovist considerably increased interpretable data by improving image quality in patients with high-grade carotid stenosis. Furthermore, the significant improvement in visualization of the residual flow lumen suggests that echo-enhancement agents may be most useful in improving the ultrasonography-based diagnosis of internal carotid occlusion.

Abstract
To identify possible genetic factors affecting human longevity we compared allele pools at two candidate loci for longevity between a sample of 143 centenarians (S) and a control sample of 158 individuals (C). The candidate loci were APOB and TPO, which code for apolipoprotein B and thyroid peroxidase, respectively. Both restriction fragment length (RFL) (XbaI2488 and EcoRI4154) and variable number of tandem repeat (VNTR) (3'APOB-VNTR) polymorphisms were analysed at the APOB locus; the TPO-VNTR polymorphism (intron 10) was analysed at the TPO locus. The main result of the investigation was that there is an association between the APOB locus and longevity that is revealed only when multiallelic polymorphisms are considered. In particular: (i) the frequency of 3'APOB-VNTR alleles with fewer than 35 repeats is significantly lower in cases than in controls; (ii) the linkage disequilibrium between the XbaI-RFLP and the EcoRI-RFLP is significantly different from 0 in cases but not in controls; (iii) the EcoRI-RFLP and XbaI-RFLP allele frequencies do not discriminate between cases and controls. The differences observed between case and control allele pools are specific to the APOB locus, since no significant difference was observed at the TPO locus.

Emergency Department echocardiography revealed an intrapericardial hollow viscus in an 80-year-old auto crash victim. This proved to be stomach herniated through a ruptured diaphragm. Echocardiography and ultrasonography are very valuable diagnostic procedures currently available to the trauma surgeon to rule out diaphragmatic injury early in the trauma room.

Abstract
Spinal neostigmine causes analgesia in animals and humans and abolishes hypotension from spinal bupivacaine in rats. Since drug distribution and action can vary with the size of the spinal cord, we tested the effects of the maximum tolerated dose of spinal neostigmine alone and with bupivacaine in conscious sheep. Neostigmine alone increased arterial blood pressure by 10%, with a statistically significant increase beginning 30 min after injection. Compared with spinal bupivacaine alone, addition of neostigmine resulted in hypotension of slower onset (15 vs 5 min), shorter duration (45 vs 105 min), and smaller magnitude (-18% +/- 3% vs -37% +/- 6%). Addition of neostigmine did not affect height of sensory block from spinal bupivacaine. These data agree with preliminary clinical reports that spinal neostigmine diminishes, but does not abolish, hypotension from spinal bupivacaine in humans.
