Abstract

STATINS: Strategy for management of patients displaying hyperlipidemia has changed since the the first statin has been launched in France more than ten years ago. Following the first primary and secondary prevention studies conducted with hyperlipidemic subjects, results have been extended to patients with cholesterol levels within normal range both in primary (AFCAPS/TexCAPS) and secondary (CARE) prevention. Drug therapy has been simplified with targets tailored to the patient's risk. OPEN QUESTIONS: Despite these important results from intervention studies with statins, other crucial questions remain. Among these questions the first one concerns the possibility that cardiovascular benefits demonstrated with statins are also partly due to other (pleiotropic) effects. This was first hypothesised when statins were proven to be efficacious after short term treatments (one year in the regression studies). The second question is whether we can extend the benefit observed in populations included in published trials to primary prevention of stroke and to the groups less well represented in previous trials including women, elderly patients. The current trends and economic strains of every health care systems have focused on evidence-based medicine and cost-efficacy studies. ROLE OF TRIGLYCERIDES: Beyond LDL-cholesterol there is clear emergence of a role of triglyceride in cardiovascular disease as well as new data on pathophysiology of the so-called reverse cholesterol transport. Recent trials including patients with hypertriglyceridemia as well as a decline of the benefit observed in hypertriglyceridemic patients strongly suggest that the use of statins may have its own limitation. IMPORTANCE OF DIET: Finally, translating results of recent trials in clinical practice remains a challenge for treating physicians who face poor compliance and difficulties in implementing diet in patients.

Laparoscopic cholecystectomy: are patients with biliary pancreatitis at increased operative risk?

BACKGROUND: Previous reports of laparoscopic cholecystectomy (LC) in patients with biliary pancreatitis suggested increased operative difficulty, high rates of conversion, and greater morbidity and mortality. METHODS: Between 1990 and 1997, LC was performed for biliary pancreatitis in 63 patients (Group I) and for other causes in 829 patients (Group II). RESULTS: Patients with biliary pancreatitis were significantly older (median age 57 vs 50 years, p = 0.009), with greater co-morbidity (ASA III/IV 24% vs 11%, p = 0.008). The groups were comparable with respect to the frequency of previous abdominal operations, acute inflammation of the gallbladder, and the frequency of bile duct calculi detected by intraoperative cholangiography. Moderate to severe adhesions involving the gallbladder were significantly more frequent in patients with biliary pancreatitis (46% vs 29%, p = 0.004). No significant differences were observed between the two groups with respect to intraoperative (1.5% Group I vs 6.0% Group II, p = 0.109) or postoperative complications (10% vs 8%, p = 0.426), conversion rate (0 vs 2.7%, p = 0.181), or duration of operation (median 92 vs 85 min, p = 0.33). CONCLUSION: Despite increased age and co-morbidity and more frequent adhesions, our data showed no evidence that intraoperative or postoperative complications were more frequent in patients with biliary pancreatitis than in other patients undergoing LC.

Modeling of pain using artificial neural networks.

In dealing with human nervous system, the sensation of pain is as sophisticated as other physiological phenomena. To obtain an acceptable model of the pain, physiology of the pain has been analysed in the present paper. Pain mechanisms are explained in block diagram representation form. Because of the nonlinear interactions existing among different sections in the diagram, artificial neural networks (ANNs) have been exploited. The basic patterns associated with chronic and acute pain have been collected and then used to obtain proper features for training the neural networks. Both static and dynamic representations of the ANNs were used in this regard. The trained networks then were employed to predict response of the body when it is exposed to special excitations. These excitations have not been used in the training phase and their behavior is interesting from the physiological view. Some of these predictions can be inferred from clinical experimentations. However, more clinical tests have to be accomplished for some of the predictions.

Visual object working memory function and clinical symptoms in schizophrenia.

OBJECTIVE: The presence of working memory deficits suggests abnormalities of prefrontal cortex (PFC) in schizophrenia. Although much is known about spatial working memory deficits in schizophrenia, including its potential as a phenotypic marker, it is unclear whether object working memory is similarly affected. Our goal was to examine nonspatial, object working memory function in relation to clinical symptoms. METHODS: We assessed object working memory and clinical symptoms in 28 schizophrenia patients during acute psychotic episode and 4 months later during partial remission. Delayed-matching-to-sample tasks for familiar object (DMTS-F) and novel shapes (DMTS-N) were used. Symptoms were assessed by the Positive and Negative Syndrome Scale (PANSS). 33 age-matched normal subjects were also tested over the same time period. RESULTS: Acutely psychotic patients showed deficits in both DMTS-F and DMTS-N. Four months later, their DMTS-F performance improved significantly but deficits in DMTS-N were still present. During acute psychosis, symptoms correlated with DMTS-F but not with the DMTS-N. Four months later, negative symptoms correlated with both tasks. CONCLUSIONS: Object working memory as measured by DMTS-N was impaired in schizophrenia patients during both acute and chronic states. When schizophrenia patients were in partial remission, object working memory was associated with negative symptoms.
