In this investigation, the measurement of trypsin levels in duodenal juice following a standard test meal (Lundh test) was evaluated as a test of pancreatic function, and a study was made of diseases and other factors which may influence its diagnostic efficiency. The method of trypsin assay, which required only basic laboratory equipment, gave a linear concentration-activity curve, with a threshold at 50 mug of crystalline trypsin per ml. Intestinal juice could be frozen and stored for up to six weeks with no detectable loss of tryptic activity. The normal control values were very similar to those found by other workers and were unaffected by the sex or age of the subject. When used to assess 32 patients in whom the presence or absence of pancreatic disease had been clearly established, the test had a diagnostic success rate of 94%. Retrospective analysis of results from 98 patients showed that trypsin levels were generally grossly reduced in patients with chronic pancreatitis or carcinoma of the head of the pancreas. Trypsin levels were normal in most patients with steatorrhoea not of pancreatic origin. Levels were generally depressed to intermediate levels in patients with a diabetic glucose tolerance, with or without steatorrhoea, but no other sign of pancreatic insufficiency. Some lowering of trypsin levels was also noted in patients having an obstruction of the common bile duct. A small but significant depression of tryptic activity was noted in patients with villous atrophy and no pancreatic disease.

We attempted to evaluate the quality of life of patients with proved long-lasting chronic pancreatitis. We measured the clinical and psychological status of 60 patients who had undergone various surgical treatments for their disease. The presence and severity of depression and other symptoms of distress were assessed, as were disease-specific functional and physical problems. Few patients had serious conditions, such as pain, malnutrition, or psychoneurotic complaints. The relation between depression and the time of onset of symptoms and of surgery appeared doubtful, and no statistically significant correlations were found between severity of emotional disturbance and other functional characteristics. Insulin-dependent diabetes and correlated diseases had the most negative influence on everyday well-being. Postoperative follow-up and the need for recurrent medical control and care did not lead to negative feelings.

To elucidate changes of pancreatic ducts in chronic pancreatitis, we observed pancreatic tissues with light microscopy and scanning electron microscopy, and corrosion casts of pancreatic ducts with scanning electron microscopy, in male WBN/Kob rats, considered a spontaneously occurring chronic pancreatitis model. At 3 months of age, hemorrhage and increased fibrosis were found in part of the pancreatic tail. After 3 months of age, pancreatic ductal lumina exhibited a winding form and inner surfaces showed long cilia and crater-like depressions. Fibrous tissues gradually extended into exocrine tissues and islets after 6 months of age. Most pancreatic ductal lumina developed a helical form with many deep depression at 14 months of age. It is suggested that increased pancreatic ductal pressure causes these findings.

There have been few studies of the psychiatric characteristics of analgesics addiction. The physician's perceptions that patients were addicted to analgesics might be partially attributable to frustration with poor response to treatment. In this retrospective study, we evaluated the medical records of 20 subjects (15 male and 5 female) who were perceived as having addiction to meperidine by general physicians. The most common medical diagnosis among these patients was chronic pancreatitis (7/20). Among them, five had a past history of suicide attempt and three had self-injury behavior during the index admission. The fact that subjects were perceived as being addicted might be attributable to a vicious cycle of the following factors: 1) chronic intractable pain; 2) poor staff-patient relationship; 3) lower pain threshold or tolerance due to anxiety or depression; 4) patients with a history or tendency of substance abuse; 5) placebo use and inadequate analgesics regimen. The findings of this study suggest that the importance of the following diagnostic and treatment procedures in these patients: 1) suicide risk should be evaluated; 2) comorbid psychiatric diseases should be treated; 3) factors that cause a vicious cycle in pain control should be identified; 4) misconceptions of opiate analgesics among medical staff should be discussed; 5) poor staff-patient relationship should be managed aggressively; and 6) "addiction" is a critical diagnosis that should be avoided if possible.

Acute zinc poisoning has been observed in dogs following the ingestion of metallic zinc objects. A 1 1/2-y-old female miniature bull terrier exhibiting anorexia, vomiting, depression, fever (39.9 C), icterus and intravascular hemolysis was diagnosed with acute zinc poisoning. Anemia, Heinz body production, azotemia and bilirubinemia were also evident. Abnormal pancreatic, hepatic and renal functions were also apparent. A radio opaque object was observed in the stomach. Based upon an elevated plasma zinc level of 28.6 ppm, a tentative diagnosis of zinc poisoning was made. Following surgical removal of the metallic zinc object, a blood transfusion and fluid therapy were given to restore the normal blood volume. Heparin, Cephazolin and Raniditine were also given, although chelation therapy was not provided. Zinc levels in the plasma declined in a steady fashion (half-life = 7.6 d). Complications, such as disseminated intravascular coagulation, chronic pancreatitis, renal or hepatic failure, were not observed. By 20 d post surgery, only mild elevation of liver enzymes was evident. Measurements of the half-life of zinc may provide a useful indication of prognosis and the success of treatment.

Based on the rheographic studies of the postprandial transformation of the splanchnic blood flow and morphological study of the resected parts of the pancreas in patients with chronic fibrosing pancreatitis, the authors revealed functional and morphological attributes of local arterial hypertension and, at the stage of exacerbation of disease--manifestations of a vascular crisis. Local arterial hypertension with vascular crises originating on its basis is an important pathogenetic factor of the progression of chronic pancreatitis. It is assumed that local arterial hypertension develops against the background of depression of cholinergic effects and domination of sympathetic effects.

Chronic pain has been associated with impaired cognitive function. We examined cognitive performance in patients with severe chronic pancreatitis pain. We explored the following factors for their contribution to observed cognitive deficits: pain duration, comorbidity (depression, sleep disturbance), use of opioids, and premorbid alcohol abuse. The cognitive profiles of 16 patients with severe pain due to chronic pancreatitis were determined using an extensive neuropsychological test battery. Data from three cognitive domains (psychomotor performance, memory, executive functions) were compared to data from healthy controls matched for age, gender and education. Multivariate multilevel analysis of the data showed decreased test scores in patients with chronic pancreatitis pain in different cognitive domains. Psychomotor performance and executive functions showed the most prominent decline. Interestingly, pain duration appeared to be the strongest predictor for observed cognitive decline. Depressive symptoms, sleep disturbance, opioid use and history of alcohol abuse provided additional explanations for the observed cognitive decline in some of the tests, but to a lesser extent than pain duration. The negative effect of pain duration on cognitive performance is compatible with the theory of neurodegenerative properties of chronic pain. Therefore, early and effective therapeutic interventions might reduce or prevent decline in cognitive performance, thereby improving outcomes and quality of life in these patients.

Chronic pancreatitis is a relentlessly painful condition associated most commonly with alcoholism. Patients suffer wasting and depression as a result of chronic pain. It is important for home care clinicians to recognize the signs of pancreatitis and understand the current evidence-based treatment strategies to control the symptoms. Although alcoholism and depression are frequent comorbidities of pancreatitis, a full discussion of alcoholism and depression is outside the scope of this article.

Today in Russian Federation, we observe significant growth of the chronic pancreatitis incidence with the depression of its therapy efficiency (more than 20% of the patients) and complications rate growth. In many respects given tendency is associated with the inefficiency of traditional medications combination in the context of inflammation process reduction, gut dysbiosis correction and chronic inflammation reaction depression. Present-day studies indicates, that the grade and character of inflammation in the pancreas depends on the pro- and anti-inflammatory cytokines balance, which is associated with the elevation of the pathogenic microbiota concentration and permeability of the gut. We estimate clinical efficacy of complex treatment regimen (PPI, spasmolytic, multienzyme and prebiotic therapy) in the patients with chronic pancreatitis and its effect on chronic system inflammation. We established that efficacy of modern complex treatment regimen depends on its influence on chronic system inflammation and that prebiotics addition potentiates correction of dysbiotic changes in the gut microbial-tissular complex and reduces grade of system inflammation.

Objective. The present study was conducted to determine if depressive symptoms were associated with variability in pain perception and quality of life among patients with nonalcohol-related chronic pancreatitis. Methods. The research design was cross-sectional, and self-report data was collected from 692 patients with nonalcohol-related, intractable pancreatitis. The mean age of the sample was 52.6 (SD = 14.7); 41% of the sample were male. Participants completed the MOS SF12 Quality of Life Measure, the Center for Epidemiological Studies 10-item Depression Scale (CESD), and a numeric rating scale measure of "pain on average" from the Brief Pain Inventory. Results. Depressive symptoms were significantly related to participants' reports of increased pain and decreased quality of life. The mean CESD score of the sample was 10.6 (SD = 6.5) and 52% of the sample scored above the clinical cutoff for the presence of significant depressive symptomology. Patients scoring above the clinical cutoff on the depression screening measure rated their pain as significantly higher than those below the cutoff (P < 0.0001) and had significantly lower physical quality of life (P < 0.0001) and lower mental quality of life (P < 0.0001). Conclusion. Although causality cannot be determined based on cross-sectional, correlational data, findings suggest that among patients with nonalcoholic pancreatitis, the presence of depressive symptoms is common and may be a risk factor associated with increased pain and decreased quality of life. Thus, routine screening for depressive symptomology among patients with nonalcoholic pancreatitis may be warranted.
