Epidemiology of Acute Pancreatitis in Southern Israel: A Retrospective Study.

BACKGROUND: There is a lack of information regarding acute pancreatitis in Israel. However, the most prevalent worldwide etiologic causes of acute pancreatitis are biliary stones and alcohol abuse. OBJECTIVES: To delineate the prevalence, main causes, rate of recurrence, mortality, and complications of acute pancreatitis in southern Israel. METHODS: In this retrospective study medical files of all hospitalized patients diagnosed with acute pancreatitis during a 13-year period were reviewed. RESULTS: The study comprised 602 patients with acute pancreatitis (120/100,000 patients or 1.2/1000 admissions). The main causes were: biliary stones (41.5%), alcohol (8.8%), and drugs (8.3%). Disothiazide was the most common drug associated with acute pancreatitis followed by sitagliptin, angiotensin converting enzyme (ACE) inhibitors, and simvastatin. Undetermined etiology made up 33.6% of the cases. Recurrence rate was 33.8% (alcohol 3.7%, hypertriglyceridemia 1.8%). This finding had no implications on mortality rate, which was stable at 4.3%. Bilateral pleural effusion, advanced computed tomography severity index (CTSI) grading, older age, and being single were found to be poor prognostic predictive factors. CONCLUSIONS: Biliary pancreatitis is the main cause of acute pancreatitis in southern Israel, similar to the rest of the world, and constitutes a much more common etiology than alcohol. Furthermore, drug-induced pancreatitis is a common etiology, with disothiazide being the most common drug associated with pancreatitis followed by ACE-Inhibitors, sitagliptin, and simvastatin. Recurrence of pancreatitis is common in this geographic area, and older age, advanced CTSI grading, bilateral pleural effusion, and being single are all poor prognostic predictive factors.

Severe Mental Illness and Acute Stress: A Study of Service Utilization in a Conflict Zone.

Patients suffering from severe mental illness (SMI) are considered especially vulnerable to stress. In this study, their use of acute stress services in a military context affecting civilian populations was assessed, using naturally occurring data. The proportion of patients with a previously known SMI, defined as any chronic psychotic disorder or bipolar disorder, among all civilians examined at a center for treatment of stress during a military conflict versus at the ER in usual times, was compared, using the Chi square statistical test. Among 354 subjects examined at the center for treatment of stress, 12 had a SMI diagnosis. Among 404 subjects examined at the ER in usual times, 16 had a SMI diagnosis. Patients with SMI were under-represented, but not in a statistically significant manner, at the center for treatment of stress (χ2 = 0.31, p = ns). Although these results may imply that patients with SMI are not more vulnerable to external stress than the general population, we believe that they may have difficulties in seeking immediate help in such traumatogenic contexts. In order to reduce the occurrence of PTSD and gain efficacy in the treatment of the primary disorder, psychiatric services should perhaps make a reaching out effort to identify and examine these patients in the community. .

The Patient-Psychiatrist Relationship on the Axis of the Other and the Same.

The patient-psychiatrist relationship is a cornerstone of psychiatric professionalism and ethics. We discuss this topic along the axis of the Other and the Same, concepts defined by continental philosophy. The self of Anglo-American philosophy is typically described in individualistic terms. Individualism, autonomy and ideal self are valorized within the current model of care. These characteristics belong to the Lacanian Imaginary Order, which is the core of narcissism. Patients may yearn for another model of interaction. For Levinas, ethics should not involve a search for perfectionism and accomplishment but responsibility toward others. Ethics is, according to him, rooted in the calling into question of one's Sameness by the other's Otherness. The question of hospitality and of the welcoming of Otherness is central to his thought. Derrida further asks whether hospitality is not an interruption of the self. Hospitality may thus become a fundamental way of re-thinking clinical practices. A relationship to the Other as an-other is characterized as of Euclidian-type, establishing borders between the self and the Other, whereas a relationship to the Other as same is characterized as of fractal-type, emphasizing similarities between self and other as same and obliterating boundaries. Winnicott's object-relating versus use of object and Buber's I-you and I-it relations are also examined along the axis of Sameness and Otherness. Since psychiatric clinical practice requires to our view adequate and adaptive to and fro movements along this axis, the two forms of relating to the Other are discussed both theoretically and through a clinical case presentation.

Environmental noise and sleep disturbances: A threat to health?

Environmental noise, especially that caused by transportation means, is viewed as a significant cause of sleep disturbances. Poor sleep causes endocrine and metabolic measurable perturbations and is associated with a number of cardiometabolic, psychiatric and social negative outcomes both in adults and children. Nocturnal environmental noise also provokes measurable biological changes in the form of a stress response, and clearly affects sleep architecture, as well as subjective sleep quality. These sleep perturbations are similar in their nature to those observed in endogenous sleep disorders. Apart from these measurable effects and the subjective feeling of disturbed sleep, people who struggle with nocturnal environmental noise often also suffer the next day from daytime sleepiness and tiredness, annoyance, mood changes as well as decreased well-being and cognitive performance. But there is also emerging evidence that these short-term effects of environmental noise, particularly when the exposure is nocturnal, may be followed by long-term adverse cardiometabolic outcomes. Nocturnal environmental noise may be the most worrying form of noise pollution in terms of its health consequences because of its synergistic direct and indirect (through sleep disturbances acting as a mediator) influence on biological systems. Duration and quality of sleep should thus be regarded as risk factors or markers significantly influenced by the environment and possibly amenable to modification through both education and counseling as well as through measures of public health. One of the means that should be proposed is avoidance at all costs of sleep disruptions caused by environmental noise.

Decrease in suicide rates after a change of policy reducing access to firearms in adolescents: a naturalistic epidemiological study.

The use of firearms is a common means of suicide. We examined the effect of a policy change in the Israeli Defense Forces reducing adolescents' access to firearms on rates of suicide. Following the policy change, suicide rates decreased significantly by 40%. Most of this decrease was due to decrease in suicide using firearms over the weekend. There were no significant changes in rates of suicide during weekdays. Decreasing access to firearms significantly decreases rates of suicide among adolescents. The results of this study illustrate the ability of a relatively simple change in policy to have a major impact on suicide rates.

CNS infection in childhood does not confer risk for later schizophrenia: a case-control study.

OBJECTIVE: The hypothesized role of CNS infection during childhood in increasing later risk of brain malfunction manifested as schizophrenia has been supported by some but not other studies. We sought to contribute to this debate by linking data on persons who had been hospitalized for meningitis as children, with a National Psychiatric Hospitalization Registry. METHOD: Data were gathered on 3599 persons who had been hospitalized for a CNS infection before the age of 16, and 6371 controls who had been hospitalized as children for gastroenteritis. Both groups were followed for later hospitalization for schizophrenia between 1970 and 2007 using the Israeli National Psychiatric Hospitalization Case Registry. Data were analyzed using Cox regression analyses. RESULTS: The mean age of the subjects at hospitalization for a CNS infection was 3.4 ± 3.6 years, mean age of the subjects at follow up was 29.3 ± 6.0 years. Compared to controls, hospitalization for any CNS infection during childhood was not associated with an increased risk of later hospitalization for schizophrenia, adjusted HR = 0.81, 95% CI: 0.5-1.32. CONCLUSIONS: Overall there was no significant association between childhood CNS infection and schizophrenia. These data do not support the presence of an infectious etiology of schizophrenia.

A major change of prescribing pattern in absence of adequate evidence: benzodiazepines versus newer antidepressants in anxiety disorders.

We performed a systematic review of controlled trials on anxiety disorders treatment (generalized anxiety disorder, panic disorder, social phobia and post-traumatic stress disorder) published from 1980 to 2006, and identified trials comparing the efficacy of benzodiazepines (BZD) with that of antidepressants, in particular comparisons between BZD and newer antidepressants. Among 969 publications, 274 double-blind randomized controlled studies remained after using our exclusion criteria. These studies comprised altogether 439 comparisons. There were in total 23 comparisons of antidepressants versus BZD. Among these, 22 compared the efficacy of older antidepressants versus BZD, whereas only 1 concerned the comparison of a newer antidepressant versus BZD. It showed comparable efficacy between venlafaxine and diazepam in the treatment of generalized anxiety disorder. Our study shows that the major change of prescribing pattern from BZD to newer antidepressants in anxiety disorders has occurred in absence of comparative data of high level of proof.

Summary of the 1st Schizophrenia International Research Society Conference oral sessions, Venice, Italy, June 21-25, 2008: the rapporteur reports.

The Schizophrenia International Research Society held its first scientific conference in Venice, Italy, June 21 to 25th, 2008. A wide range of controversial topics were presented in overlapping and plenary oral sessions. These included new genetic studies, controversies about early detection of schizophrenia and the prodrome, treatment issues, clinical characteristics, cognition, neuropathology and neurophysiology, other etiological considerations, substance abuse co-morbidity, and animal models for investigating disease etiology and for use as targets in drug studies. Young investigators in the field were awarded travel grants to participate in the congress and one of their roles was to summarize the oral sessions and subsequent discussions. The reports that follow are the culmination of this work produced by 30 young investigators who attended the congress. It is hoped that these summaries will be useful synopses of what actually occurred at the congress for those who did not attend each session or were unable to be present. The abstracts of all presentations, as submitted by the authors a few months prior, were previously published as supplement 2 to volume 102/1-3, June 2008.

Dysthymia in male adolescents is associated with increased risk of later hospitalization for psychotic disorders: a historical-prospective cohort study.

AIM: Retrospective studies indicate that patients with psychotic disorders and schizophrenia often suffer from depressive symptoms before the onset of psychosis. In a historical-prospective design, we studied the association between dysthymia in adolescence and later hospitalization for psychotic disorders and schizophrenia. METHODS: The Israeli Draft Board screens the entire, unselected population of 16-17 years old male adolescents for psychiatric disorders. These adolescents were followed for hospitalization for psychotic disorders and schizophrenia using the Israeli National Psychiatric Hospitalization Case Registry. Of 275,705 male adolescents screened, 1267 (0.5%) were hospitalized for psychotic disorders (International Classification of Diseases [ICD]-10 20.0-29.9), and 757 (0.3%) were hospitalized for schizophrenia (ICD-10 20.0-20.9) over the next 1-10 years. RESULTS: Of 275,705 male adolescents screened, 513 (0.2%) were diagnosed as suffering from dysthymia by the Draft Board. Of these adolescents, 10/513 (2.0%) were later hospitalized for psychotic disorders (including schizophrenia, HR=3.967, 95%CI (confidence intervals): 2.129-7.390), and 4/513 (0.8%) were later hospitalized for schizophrenia (HR=2.664, 95%CI: 0.997-7.116). CONCLUSIONS: In this population-based cohort of male adolescents, dysthymia was associated with increased risk for future psychotic disorders. Dysthymia in some adolescents might be a prodromal symptom, while in others it might be a risk factor for later psychosis. Clinicians assessing dysthymic adolescents should be aware that these symptoms might be part of the prodrome.

Influence of antidepressants on hemostasis.

Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), are widely used for the treatment of depression and anxious disorders. The observation that depression is an independent risk factor for cardiovascular mortality and morbidity in patients with ischemic heart disease, the assessment of the central role of serotonin in pathophysiological mechanisms of depression, and reports of cases of abnormal bleeding associated with antidepressant therapy have led to investigations of the influence of antidepressants on hemostasis markers. In this review, we summarize data regarding modifications of these markers, drawn from clinical studies and case reports. We observed an association between the type of antidepressant drug and the number of abnormal bleeding case reports, with or without modifications of hemostasis markers. Drugs with the highest degree of serotonin reuptake inhibition--fluoxetine, paroxetine, and sertraline--are more frequently associated with abnormal bleeding and modifications of hemostasis markers. The most frequent hemostatic abnormalities are decreased platelet aggregability and activity, and prolongation of bleeding time. Patients with a history of coagulation disorders, especially suspected or documented thrombocytopenia or platelet disorder, should be monitored in case of prescription of any serotonin reuptake inhibitor (SRI). Platelet dysfunction, coagulation disorder, and von Willebrand disease should be sought in any case of abnormal bleeding occurring during treatment with an SRI. Also, a non-SSRI antidepressant should be favored over an SSRI or an SRI in such a context. Considering the difficulty in performing platelet aggregation tests, which are the most sensitive in SRI-associated bleeding, and the low sensitivity of hemostasis tests when performed in case of uncomplicated bleeding in the general population, establishing guidelines for the assessment of SRI-associated bleeding complications remains a challenge.
