A Systematic Review on the Efficacy of Intravenous Racemic Ketamine for Bipolar Depression.

BACKGROUND: Ketamine, a glutamate N-methyl-d-aspartate receptor antagonist, has shown rapid antidepressant effects in treatment-resistant depression. We conducted a systematic review of studies evaluating the efficacy of intravenous ketamine augmentation in treatment-resistant depression patients with bipolar disorder. METHODS: Major databases were searched for open-label and randomized controlled trials (RCT). Two independent reviewers screened and selected the studies that met the inclusion criteria. Studies were selected following the standard Cochrane methodology, and the findings are reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Methodological quality of the included studies was assessed using standardized measures. RESULTS: A total of 1442 articles were screened. Five studies were included in the systematic review (3 RCTs and 2 open-label studies) enrolling 110 subjects (mean age, 45.54 ± 12.65 years; 68.18% female). All the RCTs and open-label studies showed improvement in depressions symptoms after receiving a single infusion of ketamine. Included studies also suggested improvement in suicidal ideation and anhedonia after ketamine infusion. Dissociation and transient increase in blood pressure were the most common reported adverse effects with ketamine. Ketamine infusions did not increase mania symptoms. CONCLUSIONS: Limited data show efficacy and feasibility of intravenous racemic ketamine in treatment-resistant bipolar depression. Further studies with larger sample size are required to strengthen the evidence.

Depression, Anxiety and Stress Among Young Farmers and Ranchers: A Pilot Study.

Agriculture has been identified as a stressful industry and there is evidence that chronic stress may contribute to the development or progression of mental health disorders, specifically anxiety and depression. Young adult farmers and ranchers may be at increased risk of mental health disorders when compared to more experienced counterparts due to additional stressors. The objectives of this study were to identify the occupational stressors of young adult farmers and ranchers in the Midwest and estimate the prevalence of anxiety and depression among this population. An online survey consisting of reliable and valid instruments was used to identify the sources of stress and prevalence of anxiety and depression among the young farming and ranching population. The survey included items related to stress, anxiety, depression, general health, and farm/personal demographics. A total of 170 young farmers and ranchers responded to the survey. The mean age of the sample was 28.9 (SD 4.4) years. Approximately 71% of respondents met the criteria for Generalized Anxiety Disorder (GAD-7 score ≥ 5) and 53% met the criteria for Major Depressive Disorder (PHQ-9 score ≥ 5). Of seven presented stress domains, personal finances and time pressures were the sources of greatest concern. Personal finances, time pressures, economic conditions, and employee relations were associated with anxiety and depression. The burden of depression and anxiety is high among young adult farmers and ranchers. Stressors commonly affiliated with farming and ranching are associated with anxiety and depression. Additional research should further explore the burden of mental health disorders among the population and examine protective factors for mental illness and opportunities for interventions.

Religiosity in Acute Psychiatric Inpatients: Relationship With Demographics, Clinical Features, and Length of Stay.

This study examined the relationship between religiosity in 175 psychiatric inpatients as measured by the subscales of the Duke University Religion Index (DUREL) and sociodemographic (age, sex, and race), clinical (primary diagnosis, suicidality, and psychotic symptoms), and outcome (length of stay [LOS] and readmission rates) measures. Psychosis was assessed by Clinician-Rated Dimensions of Psychosis Symptom Severity (CRDPSS) scale. Bivariate and multivariate analyses were used to examine the association between the DUREL subscales and the outcome measures. High scorers on the nonorganized religiosity subscale were less likely to have psychosis (47% vs. 52%; p < 0.05) but had greater psychosis severity (mean ± SD, 14.5 ± 5 vs.12.4 ± 6; p < 0.05), as measured by the CRDPSS scale, and significantly longer LOS (mean ± SD, 8.3 ± 3.8 vs. 6.9 ± 3.4; p < 0.05). Conversely, they were less likely to report previous suicide attempts than low scorers (p < 0.05). These results suggest that a brief measure of religious activities may identify psychiatric inpatients at greater risk for psychosis, suicidality, and longer hospitalizations.

Mortality associated with anxiolytic and hypnotic drugs-A systematic review and meta-analysis.

BACKGROUND: Use of hypnotics or anxiolytic drugs is common and various studies have reported increased mortality with hypnotics or anxiolytic use. OBJECTIVE: To consolidate the evidence on mortality risk associated with hypnotics or anxiolytic use METHODS: Major databases were searched through April 2014 for studies reporting mortality risk associated with hypnotics or anxiolytics use. A pooled hazard ratio with 95% confidence interval was estimated using random-effects model. RESULTS: After screening 2188 articles, 25 studies (24 cohort, 1 case-control) enrolling 2,350,093 patients with 59% females (age 18-102 years) were included in the meta-analysis. Hypnotics or anxiolytic users had 43% higher risk of mortality than non-users (hazard ratio, 1.43; 95% confidence interval, [1.12, 1.84]). Eight studies reported risk estimates for each gender category and pooled results from these studies showed increased risk of mortality among men (hazard ratio = 1.60, 95% confidence interval = [1.29,1.99]) and women (hazard ratio = 1.68, 95% confidence interval = [1.38, 2.04]). Pooled results from 10 studies showed higher mortality among benzodiazepine users compared to non-users (hazard ratio = 1.60, 95% confidence interval = [1.03, 2.49]), while pooled results from five studies showed an increased risk of mortality with Z-drugs use although the effect could not reach statistical significance (hazard ratio = 1.73, 95% confidence interval = [0.95, 3.16]). Significant heterogeneity was observed in the analyses and the quality of included studies was good. CONCLUSION: This meta-analysis suggests that hypnotics or anxiolytics drugs use is associated with increased mortality and hence should be used with caution. Future studies focused on underlying mechanism of increased mortality with hypnotics or anxiolytics use are required.

Multiple system atrophy: prognostic indicators of survival.

Neurological and autonomic presentation in multiple system atrophy (MSA) may predict early mortality. Quantification of early autonomic failure as a mortality predictor is lacking. Early neurological and autonomic clinical features were retrospectively reviewed in 49 MSA cases (median age at onset, 56.1 years; 16 women) confirmed by autopsy at Mayo Clinic. When available, the 10-point composite autonomic severity score derived from the autonomic reflex screen provided quantification of the degree of autonomic failure and thermoregulatory sweat test quantitated body surface anhidrosis. Symptoms at onset were autonomic in 50%, parkinsonian in 30%, and cerebellar in 20% of cases. Survival (median [95% confidence interval]) was 8.6 [6.7-10.2] years. Survival was shorter in patients with early laboratory evidence of generalized (composite autonomic severity score ≥ 6) autonomic failure (7.0 [3.9-9.8] vs. 9.8 [4.6-13.8] years; P = 0.036), and early requirement of bladder catheterization (7.3 [3.1-10.2] vs. 13.7 [8.5-14.9] years; P = 0.003) compared with those without these clinical features. On Cox proportional analysis, prognostic indicators of shorter survival were older age at onset (hazard ratio [95% confidence interval], 1.04 [1.01-1.08]; P = 0.03), early requirement of bladder catheterization (7.9 [1.88-38.63]; P = 0.004), and early generalized (composite autonomic severity score ≥ 6) autonomic failure (2.8 [1.01-9.26]; P = 0.047). Gender, phenotype, and early development of gait instability, aid-requiring ambulation, orthostatic symptoms, neurogenic bladder, or significant anhidrosis (thermoregulatory sweat test ≥ 40%) were not indicators of shorter survival. Our data suggest that early development of severe generalized autonomic failure more than triples the risk of shorter survival in patients with MSA.

Involuntary detention: do psychiatrists clinically justify continuing involuntary hospitalization?

To elucidate disparities in clinical and legal documentation for patients admitted involuntarily to a county psychiatric hospital in Texas. The study sample comprised of 89 randomly selected patients, involuntarily hospitalized to our facility in September 2011. All patients met criteria for involuntary detention based on the legal documents filed by admitting psychiatrists. Electronic medical records were reviewed to assess if the clinical documentation from the same date when legal documents were filed; demonstrated criteria for involuntary detention (harm to self, harm to others, inability to care for self). A logistic regression model was used to assess the predictors of concordance between legal and clinical documentation of involuntary detention criteria. Of 89, 6 patients were made voluntary, while two were discharged within 24 h, thus removed from the analysis pool. Of 81, 31(38.2 %) patients lacked sufficient clinical documentation on medical records required for involuntary hospitalization. Patients, for whom detention was justified in clinical notes, were more likely to have single marital status, longer duration of hospitalization and they were more likely to undergo commitment for further inpatient mental health treatment. Our study found that involuntary detention of many patients based on the legal documents filed by admitting psychiatrists was not justified by the clinical documentation. This indicates that appropriate standards are not maintained when completing the medical certificates for involuntary detention. Maintaining appropriate standards may reduce the need for involuntary hospitalization, increase patient autonomy, and reduce resource utilization.

Involuntary detention: comparison of clinical practices of psychiatry residents and faculty.

OBJECTIVE: The objective of this study is to study if involuntary detention criteria in legal certificates filed by psychiatry residents and faculty psychiatrists are consistent with observations in clinical documentation. METHODS: Eighty-nine involuntarily hospitalized patients were retrospectively selected from medical records; eight patients were excluded due to change in involuntary status or immediate discharge on clinical grounds. Medical certificates filed by the residents and faculty psychiatrists were compared with clinical documentation of the same day for consistency in criteria for detention (substantial risk of harm to self or others and/or inability to care for self). RESULTS: Of 81 included patients, 38.3 % lacked sufficient documentation of clinical justification for involuntary hospitalization. The rate of inconsistency of documented clinical justification showed a greater trend among psychiatry residents compared to faculty psychiatrists (p = 0.069, not statistically significant). CONCLUSIONS: Inconsistency of documented clinical justification for involuntarily detention was higher among residents compared to faculty. There is a need for structured training and supervision of psychiatry residents as well as updated training for faculty psychiatrists with regard to involuntary detention procedures.

Midodrine for orthostatic hypotension: a systematic review and meta-analysis of clinical trials.

OBJECTIVE: To perform a systematic review and meta-analysis of clinical trials evaluating the efficacy and safety of midodrine in orthostatic hypotension (OH). METHODS: We searched major databases and related conference proceedings through June 30, 2012. Two reviewers independently selected studies and extracted data. Random-effects meta-analysis was used to pool the outcome measures across studies. RESULTS: Seven trials were included in the efficacy analysis (enrolling 325 patients, mean age 53 years) and two additional trials were included in the safety analysis. Compared to placebo, the mean change in systolic blood pressure was 4.9 mmHg (p = 0.65) and the mean change in mean arterial pressure from supine to standing was -1.7 mmHg (p = 0.45). The change in standing systolic blood pressure before and after giving midodrine was 21.5 mmHg (p < 0.001). A significant improvement was seen in patients' and investigators' global assessment symptoms scale (a mean difference of 0.70 [95 % CI 0.30-1.09; p < 0.001] and 0.80 [95 % CI 0.76-0.85; p < 0.001], respectively). There was a significant increase in risk of piloerection, scalp pruritis, urinary hesitancy/retention, supine hypertension and scalp paresthesia after giving midodrine. The quality of evidence was limited by imprecision, heterogeneity and increased risk of bias. CONCLUSION: There is insufficient and low quality evidence to support the use of midodrine for OH.

Orthostatic intolerance without postural tachycardia: how much dysautonomia?

BACKGROUND: Chronic symptoms of orthostatic intolerance occur in postural tachycardia syndrome (POTS) and patients with orthostatic intolerance (OI) without tachycardia. We recently reported that deconditioning is almost universal in both patient groups. In this study, we focussed on the question of how much dysautonomia, besides orthostatic tachycardia, is there in POTS vs. OI, and how the two groups compare in regards to clinical, autonomic, laboratory, and exercise variables. METHODS: We retrospectively studied all patients referred for orthostatic intolerance at Mayo Clinic between January 2006 and June 2011, who underwent standardized autonomic and exercise testing. RESULTS: Eighty-four POTS and 100 OI fulfilled inclusion criteria, 89 % were females. The mean age was 25 and 32 years, respectively. Clinical presentation, autonomic parameters, laboratory findings, and degree of deconditioning were overall similar between the two groups, except for the excessive orthostatic heart rate (HR) rise and mild vasomotor findings observed in POTS but not in OI (slightly larger Valsalva ratio and incomplete blood pressure recovery during Valsalva). Both groups responded poorly to various medications. Severely deconditioned patients were similar to non-deconditioned patients, except for 24 h urine volume (1,555 vs. 2,417 ml), sweat loss on thermoregulatory sweat test (1.5 vs. 0.5 %), and few respiratory parameters during exercise, which are likely clinically insignificant. CONCLUSION: Though similar in clinical presentation, POTS and OI are different entities with greater, albeit still mild, dysautonomia in POTS. The clinical and pathophysiological relevance of minimal dysautonomia in the absence of orthostatic tachycardia as seen in OI remain uncertain.

Central hyperadrenergic state after lightning strike.

OBJECTIVE: To describe and review autonomic complications of lightning strike. METHODS: Case report and laboratory data including autonomic function tests in a subject who was struck by lightning. RESULTS: A 24-year-old man was struck by lightning. Following that, he developed dysautonomia, with persistent inappropriate sinus tachycardia and autonomic storms, as well as posttraumatic stress disorder (PTSD) and functional neurologic problems. INTERPRETATION: The combination of persistent sinus tachycardia and episodic exacerbations associated with hypertension, diaphoresis, and agitation was highly suggestive of a central hyperadrenergic state with superimposed autonomic storms. Whether the additional PTSD and functional neurologic deficits were due to a direct effect of the lightning strike on the central nervous system or a secondary response is open to speculation.

Takotsubo cardiomyopathy mid ventricle variant and cardiac arrest: chicken or the egg?

Takotsubo cardiomyopathy (TTC) is uncommon emergency condition usually precipitated by emotional or physical stress and is characterized by near-normal coronary arteries and regional wall motion abnormalities that extend beyond a single coronary vascular territory. Variants of TTC include classic apical ballooning syndrome and less commonly, mid, basal, and biventricular variants. Cardiac arrest is an uncommon complication of TTC. In the convalescence phase of TTC, prolonged QTc interval may cause cardiac arrest, but the reason for cardiac arrest in the acute phase when QTc interval is normal is unclear. We report 3 cases of mid ventricular TTC, with out-of-hospital cardiac arrest as the presenting feature. All 3 patients had normal QTc interval and were found to have normal coronary arteries on cardiac catheterization at presentation. Mid ventricular TTC was confirmed on contrast left ventriculography and echocardiography. Cardiac arrest myocarditis was ruled out by myocardial biopsy in 2 deceased patients and by cardiac magnetic resonance imaging in the one who survived.

Meta-analysis of Glasgow coma scale and simplified motor score in predicting traumatic brain injury outcomes.

OBJECTIVE: To perform a systematic review and meta-analysis to compare the simplified motor score (SMS) and Glasgow Coma Scale (GCS) in predicting outcomes in patients with traumatic brain injury (TBI). DATA SOURCES AND STUDY SELECTION: Ovid EMBASE, Ovid Medline, Ovid PsycInfo, evidence-based medicine reviews and Scopus and related conference proceedings were searched through 28 February 2012 for studies comparing SMS and GCS in predicting the outcomes [emergency tracheal intubation (ETI), clinically significant brain injuries (CSBI), neurosurgical intervention (NSI) and mortality] in patients with TBI. A random-effects model was used for meta-analysis. DATA SYNTHESIS: Five retrospective studies were eligible, enrolling a total of 102 132 subjects with TBI (63.4% males), with 14 670 (14.4%) ETI, 16 201 (15.9%) CSBI, 4730 (4.6%) NSI and 6725 (6.6%) mortality. Pooled AUC of the GCS and SMS were as follows: CSBI 0.79 and 0.75 (p = 0.16), NSI 0.83 and 0.81 (p = 0.34), ETI 0.85 and 0.82 (p = 0.31) and mortality 0.90 and 0.87 (p = 0.01). The difference in AUC for mortality was 0.03. Large heterogeneity between the studies was observed in all analyses (I(2 )> 50%). CONCLUSION: In patients with TBI, SMS predicts different outcomes with similar accuracy as GCS except mortality. However, due to heterogeneity and limited numbers of studies, further prospective studies are required.

Pulmonary embolism rule-out criteria (PERC) in pulmonary embolism--revisited: a systematic review and meta-analysis.

OBJECTIVES: To perform a systematic review and meta-analysis including all the current studies to assess the accuracy of pulmonary embolism rule-out criteria (PERC) in ruling out pulmonary embolism (PE). METHODS: We conducted a comprehensive search of the major databases (Ovid Medline In-Process & Other Non-Indexed Citations, Ovid MEDLINE, Ovid EMBASE, Ovid PsycInfo, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews and Scopus) and references of potentially eligible articles and conference proceedings of major emergency medicine organisations through May 2012. We included all original research studies conducted in emergency departments on diagnostic performance of PERC. Two reviewers independently identified the eligible studies and extracted data. Sensitivity, specificity and likelihood ratios were calculated using contingency tables. RESULTS: 12 studies including 13 cohorts (three retrospective, 10 prospective) were included, comprising of 14 844 patients from six countries. 12 cohorts were urban and one was rural. Pooled (95% CI) sensitivity, specificity, positive and negative likelihood ratio were 0.97 (0.96 to 0.98), 0.22 (0.22 to 0.23), 1.22 (1.16 to 1.29) and 0.17 (0.13 to 0.23), respectively. The pooled (95% CI) diagnostic OR was 7.4 (5.5-9.8). On meta-regression analysis, there was no significant difference between PE prevalence and PERC diagnostic performance (coefficient (SE) of -0.032 (0.022), p=0.173) or on relative diagnostic OR (0.97, 95% CI 0.92 to 1.02). Significant heterogeneity was observed in specificity (I(2)=97.4%) and positive likelihood ratio (I(2)=89.1%). CONCLUSIONS: Because of the high sensitivity and low negative likelihood ratio, PERC rule can be used confidently in clinically low probability population settings.

Overcoming Fear of Flying: A Combined Approach of Psychopharmacology and Gradual Exposure Therapy.

Aviophobia, the fear of flying, is a prevalent type of situational-specific phobia categorized under anxiety disorders in The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Patients with aviophobia experience intense, irrational fear when traveling by air. Active avoidance of the phobic stimulus is a diagnostic feature that affects one's quality of life and commonly leads to significant functional limitations. Virtual reality based gradual exposure therapy is a treatment option for aviophobia due to its easy accessibility and low cost, but it may not be very effective. This case reports the effectiveness of using psychopharmacologic treatment in combination with real-life gradual exposure therapy to successfully treat a patient with aviophobia. Written consent from the patient was obtained prior to the writing and submission of this case report.

Diagnostic accuracy of pulmonary embolism rule-out criteria: a systematic review and meta-analysis.

STUDY OBJECTIVE: To perform a systematic review and meta-analysis to define the diagnostic performance of pulmonary embolism rule-out criteria (PERC) in deferring the need for D-dimer testing to rule out pulmonary embolism in the emergency department (ED). METHODS: We searched EMBASE, MEDLINE, Scopus, Web of Knowledge, and all the evidence-based medicine reviews that included the Cochrane Database of Systematic Reviews through August 14, 2011, and hand searched references in potentially eligible articles and conference proceedings of major emergency medicine organizations for the previous 2 years. We selected studies that reported diagnostic performance of PERC, reported original research, and were conducted in the ED, with no language restrictions. Two investigators independently identified eligible studies and extracted data. We used contingency tables to calculate sensitivity, specificity, and likelihood ratios. RESULTS: We found 12 qualifying cohorts (studying 13,885 patients with 1,391 pulmonary embolism diagnoses), 10 prospective and 2 retrospective, from 6 countries. Pooled sensitivity, specificity, positive likelihood ratios, and negative likelihood ratios for 10 included studies were 0.97 (95% confidence interval [CI] 0.96 to 0.98), 0.23 (95% CI 0.22 to 0.24), 1.24 (95% CI 1.18 to 1.30), and 0.17 (95% CI 0.13 to 0.23), respectively. Significant heterogeneity was observed in specificity (I(2)=97.2%) and positive likelihood ratio (I(2)=84.2%). CONCLUSION: The existing literature suggests consistently high sensitivity and low but acceptable specificity of the PERC to rule out pulmonary embolism in patients with low pretest probability.

"Esketamine" in Borderline Personality Disorder: A Look Beyond Suicidality.

Borderline personality disorder (BPD) is an extremely disabling condition that affects almost every dimension of a patient's life. The S-enantiomer of ketamine (esketamine) was approved by the Food and Drug Administration (FDA) in 2019 in conjunction with an oral antidepressant for the management of treatment-resistant depression (TRD) in adults. Our patient is a 27-year-old female with a long-standing diagnosis of BPD and treatment-resistant major depressive disorder (MDD) who presented to a tertiary care hospital after a baleful suicide attempt. As per treatment guidelines, "esketamine" intranasal spray in conjunction with citalopram 20 mg was started in the outpatient setting at a dose of 56 mg twice weekly for four weeks, followed by 56 mg once weekly, which was further titrated to 84 mg once weekly. Two years into treatment, the patient and her mother report around 70% improvement in her depression and anxiety with around 80% improvement in her behavioral symptoms. Esketamine's potential action on patients with BPD can be partially explained by its very well-documented effect on the glutamate receptor antagonism. Additionally, patients with stress-induced suicidal ideations (SI), which are seen in borderline patients, are better responsive to ketamine. In conclusion, we recommend a trial of intranasal esketamine in patients with BPD with treatment-resistant MDD and frequent episodes of self-harm. Treatment with esketamine could potentially reduce the number of emergency room visits for impulsive suicide attempts and help reduce the life burden of BPD and its impact on family members.

Systematic review and meta-analysis: islet autotransplantation after pancreatectomy for minimizing diabetes.

OBJECTIVE: Islet autotransplantation (IAT) may decrease the morbidity and mortality of postpancreatectomy diabetes mellitus. The current systematic review and meta-analysis examined the rate of insulin independence (II) and mortality after IAT post-total (TP) or partial pancreatectomy (PP). METHODS: Ovid MEDLINE, EMBASE, Web of Science, SCOPUS and reference lists were searched until 31 January 2011. Eligible studies enrolled adult patients with IAT post-TP or PP, regardless of study design, sample size and language. Two investigators identified eligible studies and extracted data independently. From each study, 95% confidence intervals (CIs) were estimated and pooled using random effects meta-analysis. RESULTS: Fifteen observational studies were eligible (11 IAT post-TP, two post-PP and two including both). The II rates for IAT post-TP at last follow-up and transiently during the study were 4·62 per 100 person-years (95% CI: 1·53-7·72) and 8·34 per 100 person-years (95% CI: 3·32-13·37), respectively. In the later group, patients achieved transient II lasting 15·57 months (95% CI: 10·35-20·79). The II rate at last follow-up for IAT post-PP was 24·28 per 100 person-years (95% CI: 0·00-48·96). Whereas the 30-day mortality for IAT post-TP and post-PP was 5% (95% CI: 2-10%) and 0, respectively, the long-term mortality was 1·38 per 100 person-years (95% CI: 0·66-2·11) and 0·70 per 100 person-years (95% CI: 0·00-1·80) respectively. CONCLUSIONS: IAT postpancreatectomy offers some patients a chance for insulin independence. Better data reporting are essential to establish the risks and benefits of IAT after pancreatic surgery.

Metabolic and target organ outcomes after total pancreatectomy: Mayo Clinic experience and meta-analysis of the literature.

INTRODUCTION: Total pancreatectomy (TP) has been associated with substantial metabolic abnormalities and poor glycaemic control limiting its use. Because data reported to date are limited, we evaluated outcomes related to the diabetes mellitus obligated by TP. METHODS: A case series study of all patients who underwent TP from 01/01/1985 to 12/31/2006 at Mayo Clinic was conducted. TP cases were summarized according to perioperative procedures, mortality and morbidity after TP. To complement this retrospective examination, a survey was developed to measure DM treatment modality, target organ failure and complications in patients alive in 2007. We performed a meta-analysis to compare our results with similar previous studies and provide overall estimates of outcomes. RESULTS: A total of 141 cases were studied (97 malignant diseases, 44 benign diseases). The median survival was much less for malignant pathology (2·2 vs 8·7 years, Log rank P = 0·0009). In 2007, there were 59 patients that were presumed alive and 47 (80%) responded to the survey. Mean HbA1c at last follow-up was 7·5% with 89% of respondents on a complex insulin programme (mean daily insulin requirement 35 ± 13 units). Episodic hypoglycaemia was experienced by 37 (79%); 15 (41%) experienced severe hypoglycaemia. In contrast, diabetic ketoacidosis developed in only 2 (4%). Target organ complications and chronic diarrhoea developed in 13 patients (28%) each. CONCLUSION: The primary factor determining survival after TP is the aetiology necessitating TP, i.e. pancreatic malignancy. Most respondents used complex insulin programmes, but hypoglycaemia continues to be a problem.
