Uncommon acquired fistulae involving the digestive system: summary of data.

PURPOSE: Most gastrointestinal fistulae commonly occur following surgery. A minority is caused by a myriad of other etiologies and is termed by some as "uncommon fistulae". The aim of this study was to review these fistulae and their treatment. METHODS: A literature review was carried out. Searches were conducted in Pubmed and related references reviewed. RESULTS: Except for Crohn's disease and diverticulitis, "uncommon fistulae" are described in case reports or very small case series. Most of the patients were treated by surgery. CONCLUSIONS: The anatomic features of the fistula and the etiology usually dictate the approach. Most patients will eventually need surgery to resolve this pathology.

Quality of life profiles and changes in the course of maintenance treatment among 1,015 patients with severe opioid dependence.

INTRODUCTION: Studies indicate that different areas of mental, physical, social and daily life functioning need to be considered in order to improve intervention outcomes in substance user patients. The aim of the study was to assess health-related quality of life (HRQOL) in patients diagnosed with opioid dependence as compared to healthy controls and patients diagnosed with depression and schizophrenia. METHODS: A total of 1,015 outpatients diagnosed with opioid dependence were investigated during 12 months of maintenance treatment. HRQOL (MSQoL), addiction (EUROP-ASI), and sociodemographic characteristics were assessed. RESULTS: HRQOL in opioid dependence improved significantly (p < .001), but was lower as compared to that of healthy controls and patients diagnosed with schizophrenia. HRQOL in opioid dependence comprises addiction-specific aspects, most importantly low material satisfaction, physical health, and social stability. CONCLUSIONS: HRQOL measurement provides valuable information for course and outcome in opioid dependence treatment.

Quality of life under maintenance treatment with heroin versus methadone in patients with opioid dependence.

BACKGROUND: There is increasing evidence that health-related quality of life (HRQOL) is associated with a successful treatment and better outcome in opioid addiction. The aim of the present study was the longitudinal investigation of HRQOL in patients with severe opioid dependence, who were randomly assigned to four groups of medical and psychosocial treatment: heroin (diacetylmorphine) versus methadone and case management (CM) versus psychoeducation (PSE) respectively. METHODS: HRQOL (MSQoL) and physical health (OTI) were investigated in 938 subjects, who participated in the German multi-centre study examining the effects of heroin-assisted treatment in patients with severe opioid dependence. Data for the present analysis were taken from baseline and 12-month follow up. RESULTS: Under both forms of maintenance and psychosocial treatment HRQOL improved significantly during the observation period. HRQOL improvement under maintenance with heroin exceeded improvement under methadone, especially with regard to subjective physical health. HRQOL improvement was significantly associated with better expert-rated physical health. Further analyses showed significant better improvement of HRQOL in subjects treated with PSE compared with CM. CONCLUSIONS: The advantage of heroin with regard to the improvement of HRQOL may be partially explained by a better improvement of physical health under maintenance with heroin compared with methadone, which highlights the importance of a comprehensive model of health care for patients with severe opioid dependence. Future studies need to investigate the benefits of PSE for patients in maintenance therapy.

Intestinal intussusception in elderly patients.

Intussusception is the most common cause of bowel obstruction in children, but it is a very rare cause of bowel obstruction in the elderly. Diagnosis is based on a high index of suspicion, complete anamnestic recall, physical examination, and imaging modalities. We find abdominal CT scans to be highly sensitive and accurate for making the diagnosis. Treatment of intussusception in adults is always surgical. Segmental bowel resection must be performed. The extent of resection should include any nonviable bowel as well as the leading point of the intussusception. We present a case of an 82-year-old patient with ileo-cecal intussusception, followed by a discussion of the diagnostic and therapeutic options.

Association of personality disorders, family conflicts and treatment with quality of life in opiate addiction.

AIM: The purpose of this study was to investigate the association of the current status and longitudinal changes in different clinical and social variables with quality of life (QOL) in opiate addiction. Our hypotheses were that drug use, comorbid personality disorders and social problems are associated with worse QOL. METHODS: 107 participants with long-term opiate addiction were included and interviewed at entry with the Europ-ASI and the PDQ-R. QOL (SF-36) and changes in different domains of the Europ-ASI were assessed after 2 years. RESULTS: Personality disorders, interpersonal conflicts with the family or partner and ongoing need for somatic and psychiatric treatment were significantly associated with worse subjective QOL, whereas changes in drug and alcohol use, the economic situation, legal problems and social problems with persons outside of the family showed no relevant association with QOL. CONCLUSION: Our results provide support for an emphasis in treatment on helping clients to reduce intra- and interpersonal conflicts according to comorbid conditions and among family members and partnerships. In addition, the present data provide further support for the advantages of extended interventions in long-term opiate addiction.

Is mechanical bowel preparation mandatory for left-sided colonic anastomosis? Results of a prospective randomized trial.

BACKGROUND: Preoperative mechanical bowel preparation is aimed to reduce the risk of infectious complications, and its utility is a dogma in left-sided large bowel anastomosis. The aim of this study was to specifically assess whether colocolonic and colorectal anastomoses may be safely performed without preoperative mechanical bowel preparation. METHODS: Patients undergoing elective colon and rectal surgery with primary colocolonic or colorectal anastomosis were prospectively randomized into two groups. The "prep" group had mechanical bowel preparation prior to surgery, while the "non-prep" group had surgery without pre-operative mechanical bowel preparation. RESULTS: Two hundred forty-nine patients were included in the study, 120 in the prep group and 129 in the nonprep group. Demographic characteristics, indications for surgery, and type of surgical procedure did not significantly differ between the two groups. There was no difference in the rate of surgical infectious complications between the two groups. Overall infectious complication rate was 12.5% in the prep group and 13.2% in the non-prep group. Wound infection, anastomotic leak, and intra-abdominal abscess occurred in 6.6%, 4.2%, and 1.6% of patients in the prep group and in 10.0%, 2.3%, and 0.7% of patients in the nonprep group, respectively (p=NS). CONCLUSIONS: These results suggest that elective left-sided anastomosis may be safely performed without mechanical preparation. Multicenter studies to test the reproducibility of these results are required, to support a change in this time-honored practice.

PANSS syndromes and quality of life in schizophrenia.

BACKGROUND: Results from factor analysis studies have suggested that a five-dimensional structure appears to be a better representation of the psychopathological data of the PANSS. The purpose of this study was the detailed investigation of the association of schizophrenia syndromes and single symptoms with quality of life (QOL) in acute and remitted patients. The leading hypotheses were: (1) affective symptoms, especially depression and anxiety, are mostly associated with QOL longitudinally and (2) in the acute phase, QOL is also associated with positive schizophrenia symptoms. METHODS: For the present study, schizophrenia and schizophreniform patients were studied on admission, at the end of the acute phase and 6 months after hospitalization. Psychopathology was measured using the PANSS syndromes, QOL was assessed using disease-specific (SWN) and generic (MLDL, EDLQ) scales. RESULTS: Eighty-four patients entered the study and were assessed during the acute phase taking into account their history and actual treatment. Results revealed anxiety as the most important symptom and depression as the most important syndrome associated with different areas of QOL during and after hospitalization. Also cognitive and negative symptoms were associated with different QOL domains, but both positive symptom clusters showed no substantial association with QOL. CONCLUSIONS: Results of this longitudinal study investigating psychopathology and QOL in schizophrenia provide further support for the need to consider the psychopathological state and treatment setting when measuring QOL in schizophrenia and the need for a differential analysis of schizophrenia symptoms and QOL in the acute, mid-term and long-term phase. Anxiety reduction should be a critical goal of treatment in order to prevent further QOL impairment.

Correlates of subjective well-being in schizophrenic patients treated with atypical antipsychotics.

Objective A growing body of research indicates that a low subjective well-being (SW) may be predictive of non-adherence and less favourable outcome. This study examined baseline variables and variables in the course of treatment hypothesised to be associated with later SW. Methods Sixty-three inpatients with schizophreniform disorder or schizophrenia were randomly assigned to treatment with various atypical antipsychotics after a wash-out phase of 2 days. Subjects were evaluated with a protocol that examined psychopathology (Positive and Negative Symptom Scale, PANSS), side effects (Scandinavian Society of Pharmacology, UKU), and subjective well-being (Subjective Well-being under Neuroleptic treatment, SWN) at baseline and endpoint (mean duration of treatment 39.9 days). Two-thirds of subjects were multiple episode schizophrenic inpatients pre-treated with antipsychotics. Results Multiple regression analyses revealed that the PANSS negative score, neurological side effects, and SWN at baseline, as well as change of the PANSS positive score between baseline and endpoint, were associated independently with SW at endpoint (R(2)=0.55 after exclusion of two subjects). Conclusions Patients with low SW, severe negative symptoms, and neurological side effects, all at baseline, as well as those without improvement or deterioration of positive symptoms are at risk of low SW later in treatment and, most likely, of non-adherence.

Diagnostic laparoscopy for penetrating injuries in the thoracoabdominal region.

BACKGROUND: The role of laparoscopy in diagnosis of penetrating abdominal injuries is still controversial. In the present investigation diagnostic laparoscopy was studied in penetrating injuries of the thoracoabdominal region. METHODS: Between March 1998 and June 2003, 43 patients with penetrating thoracoabdominal injuries underwent diagnostic laparoscopy at the Rambam Medical Center. There were 41 males and two females; the average age was 30 years (range, 16-54 years). Thirty-one patients had a lower chest injury, eight patients had an upper abdomen and flank injury, and four patients had combined chest and abdomen injuries. In 11 patients intraperitoneal penetration was diagnosed. In 10 patients the procedure was converted to open laparotomy, and one patient with a small laceration of the right diaphragm opposite the liver was observed without laparotomy. RESULTS: The average operating time for the laparoscopy was 25 min (10-45 min), and 85 min (40-175 min) for laparotomy. Patients who underwent laparoscopy were discharged after an average of 1.6 (1-3) days, while those who underwent laparotomy were discharged after an average of 7.6 (2-15) days. CONCLUSIONS: Laparoscopy is a useful diagnostic tool in penetrating injuries of the chest, thoracoabdominal region, and flank. This procedure is particularly reliable in diaphragmatic tears. Laparoscopy should be considered the procedure of choice for the evaluation of penetrating injuries of the lower chest and upper abdomen for diagnosis of peritoneal penetration.

Traumatic abdominal hernia associated with large bowel strangulation: case report and review of the literature.

A rare case of traumatic rupture of the abdominal wall with ventral herniation and strangulation of the right colon is presented. The defect was detected by computed tomography on admission. The patient was operated on 3 days after injury, and irreversible ischaemia of the right colon was found. Right hemicolectomy was performed. The pathogenesis and treatment of this complication is discussed.

Lipopolysaccharide endotoxemia reduces cell proliferation and decreases enterocyte apopotosis during intestinal adaptation in a rat model of short-bowel syndrome.

Sepsis is frequently associated with or complicates short-bowel syndrome (SBS). To investigate the effects of lipopolysaccharide (LPS) endotoxemia on enterocyte proliferation and death via apoptosis in a rat model of SBS, adult male Sprague-Dawley rats were divided into three experimental groups: sham rats underwent bowel transection and reanastomosis; SBS rats underwent 75% small-bowel resection; and SBS-LPS rats underwent 75% bowel resection and were given intraperitoneal injections of LPS 10 mg/kg. Parameters of intestinal adaptation (bowel and mucosal weights, mucosal DNA and protein, villus height, and crypt depth), enterocyte proliferation, and death via apoptosis were determined on day 15 after the operation. Statistical analysis was determined by Student's and ANOVA tests with a P less than 0.05 considered significant. SBS-LPS animals demonstrated a significant decrease (vs SBS rats) in duodenal (20%), jejunal (30%), and ileal (15%) overall weight, duodenal (20%), jejunal (27%), and ileal (18%) mucosal weight, jejunal (20%) and ileal (30%) mucosal DNA, jejunal (29%) and ileal (31%) villus height, and jejunal (14%) and ileal (29%) crypt depth. LPS endotoxemia led to reduced cell proliferation and enterocyte apoptosis compared to untreated SBS animals. Thus, in a rat model of SBS, LPS endotoxemia inhibits intestinal adaptation. A possible mechanism may be decreased cell proliferation. Decreased enterocyte loss via apoptosis may reflect a reduced number of enterocytes. Other mechanisms (necrosis) may be mainly responsible for cell death following LPS injection.

Efficacy review of antipsychotics.

Antipsychotic drugs have been available for more than 40 years. The invention of neuroleptics changed the overall treatment of schizophrenia dramatically. Nevertheless, the discussion on the importance and role of antipsychotic therapy still goes on. In the public as well as in the media, there remains a great deal of scepticism about the role of psychopharmacotherapy in the treatment of schizophrenia. The best way to handle this is an evidence-based approach. The efficacy of neuroleptic treatment has been proven in over 150 double-blind, controlled clinical trials. The second generation of antipsychotic drugs show similar antipsychotic properties as the classical agents, but with fewer side-effects such as extrapyramidal symptoms (EPS). The atypical antipsychotic agents have improved the quality of therapy and can also improve and support other aspects of treatment. When used with other treatment strategies, atypical antipsychotic agents could improve the overall outcome of this usually chronic disease. It is now necessary to implement these strategies as effectively as possible.

[Atypical neuroleptics in the treatment of aggression and hostility in schizophrenic patients]. / Atypische Neuroleptika in der Behandlung von Aggressivität und Feindseligkeit bei schizophrenen Patienten.

The treatment of aggressive symptoms in schizophrenic patients is a relevant clinical problem. We systematically review the efficacy of the different atypical neuroleptics on acute or persistent aggressive symptoms also regarding methodological problems. Currently typical neuroleptics are still first choice in treating acute aggressive symptoms, while risperidone and olanzapine could be alternatives. In persistent aggression clozapin shows the best specific results. Typical depot neuroleptics should be considered in cases when medication compliance is a problem.

Relationship between neuroleptic dosage and subjective cognitive dysfunction in schizophrenic patients treated with either conventional or atypical neuroleptic medication.

Previous research has suggested that high doses of conventional neuroleptics may induce neurocognitive deficits when assessed with standard tasks. However, little is known about the effects of high doses of neuroleptics (conventional or atypical) on subjective cognitive dysfunction. Recent research stresses the putative importance of self-reported cognitive deficits for both symptomatic outcome and medication compliance. The aim of the present study was to investigate the impact of neuroleptic medication on subjective cognition in patients treated with either conventional or atypical agents (clozapine, risperidone, olanzapine). Patients were asked to endorse the items of a questionnaire entitled 'Subjective Well-Being under Neuroleptic Treatment' prior to discharge. Subjective impairment, as assessed with the subscale 'mental functioning', was significantly correlated with greater conventional neuroleptic dosage after controlling for psychopathology (P<0.05). The difference between patients medicated with higher doses of conventional neuroleptics and those with lower doses was highly significant (P<0.001). In contrast, higher atypical neuroleptic doses were not associated with impairment.

Cocaine use and the utilisation of drug help services by consumers of the open drug scene in Hamburg.

In order to describe the patterns of use in the open drug scene in Hamburg, a study was carried out among 616 drug users in the drug scene and in or in the vicinity of low-threshold institutions close to the drug scene in summer 2000. The special focus was on the prevalence of cocaine and crack use as well as on the utilisation of help services for drug users. 80% of the interviewed persons were male, the average age was 32.6 years. They had been using drugs such as heroin or cocaine for an average of 11 years. 84% had used heroin and 74% cocaine within the last 24 h. Use was intravenous for 66%. 57% used cocaine intravenously, the percentage of crack smokers was 22%. Compared to previous studies, an increase in cocaine use can be noted among the scene users in Hamburg, mainly related to intravenous cocaine use. Crack smoking has only increased slightly over the past few years. Based on cluster analysis, four consumption pattern groups can be established. The largest group (38%) mainly uses cocaine and heroin. The second group (26%) consists of polyvalent drug consumers using methadone in addition to heroin and cocaine, as well as, partially, benzodiazepines, cannabis or alcohol. Group 3 (19%) mainly uses heroin only, some of them also using methadone and/or cannabis. The fourth group (17%) is mainly related to alcohol, the greater part of them additionally using heroin. On the whole, it appears that those users who currently do not use cocaine (or crack) are in a better health and social situation. The group using only heroin (cluster 3) also compares favourably with the other three consumption pattern groups with regard to the intensity of use, consumption in public and risk behaviour. Almost all the interviewed persons are in contact with general practitioners. However, the increasing cocaine use has not been met by sufficient intervention and treatment programmes so far.

Crystalloid and colloid resuscitation of uncontrolled hemorrhagic shock following massive splenic injury.

Using a standardized massive splenic injury (MSI) model of uncontrolled hemorrhagic shock we studied the effect of vigorous crystalloid or colloid fluid resuscitation on the hemodynamic response, and survival in rats. The value of massive fluid infusion in uncontrolled hemorrhagic shock following intra-abdominal solid organ injury is still controversial. The effect of crystalloid and colloid infusion was studied following massive splenic injury. The animals were randomized into six groups: group 1 (n = 8) sham-operated, group 2 (n = 12) MSI untreated, group 3 (n = 10) MSI treated with 41.5 mL/kg Ringer's lactate (large-volume Ringer's lactate, LVRL), group 4 (n = 14) MSI treated with 5 mL/kg 7.5% NaCl (hypertonic saline, HTS), group 5 (n = 10) MSI treated with 7.5 mL/kg hydroxyethyl starch (HES-7.5), and group 6 (n = 11) MSI treated with 15 mL/kg hydroxyethyl starch (HES-15). Following MSI mean arterial pressure (MAP) in untreated group 2 decreased from 109.1 +/- 4.5 to 49.8 +/- 9.6 mmHg (P < 0.001) in 60 min. Mean survival time was 132.1 +/- 18.7 min, and total blood loss was 30.2 +/- 4.1% of blood volume. LVRL infusion resulted in an early rise in MAP from 59.7 +/- 7.3 to 90.0 +/- 11.3 mmHg (P < 0.01), which then rapidly dropped to 11.7 +/- 4.5 mmHg (P < 0.001) after 60 min. The mean survival time was 82.5 +/- 18.2 min (P < 0.01), and total blood loss was 53.7 +/- 2.9% (P < 0.01). Total blood loss following HTS infusion was 32.2 +/- 4.0% and survival time was 127.9 +/- 19.7 min. HES-7.5 infusion only moderately increased bleeding to 44.2 +/- 3.9% (P < 0.05), but mortality remained unchanged. HES-15 infusion resulted in an increase in blood loss to 47.8 +/- 7.1% (0.01), survival time dropped to 100.7 +/- 12.3 min (P < 0.05). Vigorous large volume infusion of Ringer's lactate or HES following MSI resulted in a significant increase in intra-abdominal bleeding and shortened survival time compared to untreated, small volume HTS, or HES-7.5-treated animals. The hemodynamic response to crystalloid or colloid infusion in blunt abdominal trauma is primarily dependent on the severity of injury and the rate of fluid resuscitation.

[Psychotic experiences in a transcultural context - case report analysis on the importance of the second language for the therapeutic process]. / Psychotisches Erleben im transkulturellen Spannungsfeld - Eine kasuistische Analyse der Bedeutung der Zweitsprache für den therapeutischen Prozess -

The use of the second language among migrants can lead to a separation of affect and content of speech, which can be used in therapy when touching upon emotionally strenuous events. On the basis of 3 case reports of migrants of Turkish origin with a psychotic disorder, the importance of the second language when used by a native speaking therapists is analyzed. This can lead to the establishment of a therapeutic alliance, even though emotionally central themes are avoided in the process.

Neuropsychological correlates of schizophrenic syndromes in patients treated with atypical neuroleptics.

There is widespread evidence that schizophrenic symptomatology is best represented by three syndromes (positive, negative, disorganized). Both the disorganized and negative syndrome have been found to correlate with several neurocognitive dysfunctions. However, previous studies investigated samples predominantly treated with typical neuroleptics, which frequently induce parkinsonian symptoms that are hard to disentangle from primary negative symptoms and may have inflated correlations with neurocognition. A newly developed psychopathological instrument called the Positive and Negative and Disorganized Symptoms Scale (PANADSS) was evaluated in 60 schizophrenic patients. Forty-seven participants treated with atypical neuroleptics performed several neurocognitive tasks.A three-factor solution of schizophrenic symptomatology emerged. Negative symptomatology was associated with diminished creative verbal fluency and digit span backward, whereas disorganization was significantly correlated with impaired Stroop, WCST and Trail-Making Test B performance.Data suggest that disorganization is associated with tasks that demand executive functioning. Previous findings reporting correlations between negative symptomatology and neurocognition may have been confounded by the adverse consequences of typical neuroleptics.
