Abstract
Delirium is the most common psychiatric diagnoses encountered in patients with various medical-surgical illnesses, in all the treatment set-ups, with relatively higher incidence and prevalence in the intensive care units. As delirium is encountered in multiple specialties, it is important to understand the research on this diagnosis. This study aims to assess the research output involving patients of delirium from India. A comprehensive search was undertaken using Medline (PubMed) and other databases. Search words included were “delirium,” “delirious,” “delirium tremens” AND “India.” No filters were used. Internet and hand searches yielded 305 articles. Out of these articles, 151 had the terms “delirium,” “delirious,” “delirium tremens” in the title and these were included for the review. Additionally, 14 articles were included for the review, although these did not have these terms in the title, but delirium was one of the major outcome parameters in these studies. Majority of the papers were original articles (
n
= 81), and these were followed by, case reports (
n
= 58), review articles (
n
= 10), letter to the editor (not as case reports but as a communication;
n
= 13), editorials (
n
= 2) and one clinical practice guideline. Most of the original papers have either focused on epidemiology (incidence, prevalence, outcome, etc.), symptom profile, with occasional studies focusing on effectiveness of various pharmacological interventions. There is a dearth of research in the field of delirium from India. There is a lack of studies on biomarkers, evaluation of nonpharmacological interventions, and evaluation of prevention strategies. It is the need of the hour to carry out more studies to further our understanding of delirium in the Indian context.

Kınay D, Soyata AZ. Biperiden-Induced Delirium In A Five-Years Old Child. Curr Drug Saf 2019; 14:48-50. [PMID: 30370855 DOI: 10.2174/1574886313666181029101830] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Revised: 10/16/2018] [Accepted: 10/22/2018] [Indexed: 11/22/2022]
Abstract
OBJECTIVE Extrapyramidal adverse effects of antipsychotic drugs are more reported in children. Biperiden is an anticholinergic agent to treat the adverse effects of antipsychotic drugs. The drug has the potential to induce delirium at toxic doses. However, data are scarce about delirium associated with biperiden in children. Thus far, a case of delirium has been associated with biperiden in an adolescent patient. We report the first case of delirium associated with the use of biperiden in a preadolescent patient. CASE REPORT A boy aged five years and weighing 20 kilograms had been diagnosed as having oppositional defiant disorder and separation anxiety disorder in the previous treatment center. Ten milligrams fluoxetine and 0.25 milligrams risperidone had been initiated. On the third day of treatment, dystonia developed and he was administered with biperiden. An hour later, he was brought to our emergency clinic due to disorganized speech and behavior. His vital signs were stable. There were no findings in blood and urine tests. No electrolyte imbalance, liver, kidney, and thyroid dysfunction have been observed. His neurologic examination was unremarkable and no abnormal findings were shown on cranial magnetic resonance imaging. No other system findings or findings pointing out to infectious diseases have been observed. One milligram physostigmine was administered with intravenous infusion. However, symptoms did not resolve and he was diagnosed with delirium. Naranjo Adverse Drug Reaction Probability Scale score was seven, indicating a "Probable" Adverse Drug Reaction. Half milligram haloperidol was administered bid for three days and he was discharged with complete recovery. CONCLUSION Clinicians must be aware of the risk of delirium when using non-toxic doses of biperiden in young children.

Abstract
: Purpose: The purpose of this study was to examine the evidence regarding the risk factors for and characteristics of acute pediatric delirium in hospitalized children. METHODS The systematic review method within an epidemiological framework of person, place, and time was used. Fifty-two studies were selected for initial retrieval. Of these, after assessment for methodological quality, 21 studies involving 2,616 subjects were included in the review. RESULTS Findings revealed five primary characteristics seen in children experiencing delirium: agitation, disorientation, hallucinations, inattention, and sleep-wake cycle disturbances. Children who were more seriously ill, such as those in a pediatric ICU (PICU) and those with a high Pediatric Risk of Mortality II (PRISM II) score, and children who were mechanically ventilated were at greater risk for development of delirium. Those with a developmental delay or a preexisting anxiety disorder were also more prone to delirium. Although delirium symptoms fluctuate, most episodes occurred at night. Boys were slightly more susceptible than girls, though this difference was not significant. A key finding of this review was that delirium is multifactorial, related to treatment (mechanical ventilation, for example) and to a hospital environment (such as a PICU) that deprives patients of normal sleep-wake cycles and familiar routines. CONCLUSION These findings will be useful in efforts to achieve earlier recognition and better management or prevention of pediatric delirium. This may also help to prevent unnecessary laboratory testing and imaging studies, which can cause children and parents unnecessary pain and anxiety and increase hospital costs.

Abstract
INTRODUCTION Delirium is an acute and often fluctuating disturbance in level of consciousness and thought process (cognition) that develops over a short period of time and is a significant change from previous level of functioning. Its prevalence increases with age, complexity of medical co- morbidities and number of medications prescribed. AIM To compare the cause and severity of delirium in patients in emergency and consultation liaison psychiatry group. MATERIALS AND METHODS A cross-sectional, tertiary care hospital based study was conducted on the patients who presented with delirium from emergency department (50) and consultation-liaison psychiatry groups (50), over a period of one year. The diagnosis was made on the basis of DSM- 5 criteria. The Delirium Rating Scale (DRS-R-98) was applied to know the severity of delirium, cognitive and non-cognitive symptoms of delirium in patients. The results were subjected to appropriate statistical analysis. RESULTS In emergency group, 42% patients had metabolic abnormalities, while in consultation-liaison, 38% patients had hyponatremia and hypokalemia and the difference was found to be statistically non-significant (p>0.05). In emergency group, 21(42%) patients were diagnosed as delirium due to other medical condition, followed by 13 (26%) and 8(16%) patients, who were diagnosed as delirium due to multiple aetiologies and substance intoxication each respectively. In only 33(66%) cases in consultation liaison group patients had delirium secondary to other medical conditions. As per DRS-R98 Scale, mean severity score was found to be statistically significant (p<0.05) in consultation liaison group as compared to emergency department group (p> 0.05). CONCLUSION Delirium is multifactorial aetiological disease, with variable but preventable outcome. Approach should be aimed at finding the treatable causes to reduce morbidity and mortality.

Abstract
OBJECTIVE To explore the frequency of different motor subtypes of delirium in children and adolescents and to study the relationship of motor subtypes with other symptoms, etiology and outcome of delirium. METHODS Forty-nine consecutive patients, aged 8-19 years, diagnosed as having delirium as per DSM-IV-TR were assessed on Delirium Rating Scale-Revised 98 (DRS-R-98), amended Delirium Motor Symptom Scale (DMSS), delirium etiology checklist and risk factors for delirium. Different motoric subtypes of delirium were compared with each other for symptoms of delirium as assessed by DRS-R-98, risk factors, etiology and outcome. RESULTS More than half (53%) of patients were classified as having hyperactive delirium, this was followed by the mixed (26.5%) and the hypoactive (16%) subtype. When the different subtypes were compared with each other, the 3 motor subtypes did not differ from each other in terms of frequency and severity of other symptoms except for minor differences. Hallucinations are more common in patients with hyperactive and mixed subtype. There is no significant difference in the outcome of delirium across different subtypes. CONCLUSION Unlike in adults, motoric subtypes of delirium in child and adolescents do not differ from each other with respect to other symptoms, risk factors and outcome.

Abstract
PURPOSE To study the caregiver's distress with symptoms of delirium. DESIGN AND METHODS Consenting adult caregivers (>18 years of age) of patients with delirium were evaluated for the distress due to symptoms of delirium. RESULTS The study included 72 primary caregivers of patients with delirium. Symptoms of delirium that led to severe or very severe distress in more than two thirds of the caregivers included decreased sleep, increased motor activity, attempts to remove intravenous lines, tubings, etc., and attempts to get out of bed when they were actually required to lie down. CONCLUSIONS Overall experience of delirium was very distressing for the caregivers.

Symptom profile of delirium in children and adolescent--does it differ from adults and elderly? Gen Hosp Psychiatry 2012; 34:626-32. [PMID: 22516219 DOI: 10.1016/j.genhosppsych.2012.03.003] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2012] [Revised: 03/03/2012] [Accepted: 03/06/2012] [Indexed: 02/08/2023]
Abstract
OBJECTIVE The objective was to evaluate the phenomenology, etiology and outcome of delirium in children and adolescents (8-18 years of age) seen in a consultation-liaison psychiatric service in India. Additionally, an attempt was made to compare the phenomenology with adult and elderly patients with delirium. METHOD Thirty children and adolescents (age 8-18 years) diagnosed with delirium by the consultation-liaison psychiatry team were rated on the Delirium Rating Scale-Revised-98 (DRS-R-98) and compared with DRS-R-98 data on 120 adults and 109 elderly patients. RESULTS The commonly observed symptoms in children and adolescents with delirium were disturbance in attention, orientation, sleep-wake cycle disturbances, fluctuation of symptoms, disturbance of short-term memory and motor agitation. The least commonly seen symptoms included delusions and motor retardation. Compared to adults, children and adolescents had lower frequency of long-term memory and visuospatial disturbances. Compared to the elderly, children and adolescents had higher frequency of lability of affect. For severity of symptoms, compared to adults, the children and adolescents had lower severity of sleep-wake disturbances, abnormality of thought, motor agitation, orientation, attention, short-term memory, long-term memory and visuospatial abilities. When compared to elderly patients, children and adolescents had higher severity of lability of affect and lower severity of language disturbances, short-term memory and visuospatial abilities. CONCLUSIONS In general, phenomenology, of delirium in children and adolescents (age 8-18 years) is similar to that seen in adults and elderly patients.

Abstract
OBJECTIVE To evaluate the incidence, prevalence, risk factors and outcome of delirium in the respiratory intensive care unit of a tertiary care hospital. METHODS Consecutive patients admitted to an eight-bed respiratory intensive care unit were screened for presence of delirium by a psychiatrist. Patients found to have delirium were evaluated using univariate techniques for their clinical profiles, risk factors for delirium, Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, duration of stay (in days) and outcome at discharge from intensive care unit besides evaluation on Delirium Rating Scale-Revised 98 version (DRS-R-98). RESULTS Incidence and prevalence rate of delirium were 24.4% and 53.6% respectively. Univariate analyses revealed that the prevalence of delirium was higher (64%) in mechanically ventilated patients. The predisposing risk factors identified for delirium in univariate analysis were higher age; higher Glasgow Coma Scale score; increased APACHE II score; hyperuricemia; hypoalbuminemia; presence of acidosis; abnormal alkaline transferase levels; use of mechanical ventilation; higher number of total medication received and use of sedative, steroids and insulin. Univariate analysis showed that patients who were diagnosed with delirium had significantly longer duration of intensive care unit (ICU) stay and higher mortality rates. Age, multiple organ failure, hypoactive delirium and higher DRS-R-98 scores were significant risk factors for mortality in patients with delirium. CONCLUSIONS Delirium is highly prevalent in the ICU setting and delirium is associated with longer ICU stay and higher mortality.

Abstract
A 15-year-old female patient with known type 1 diabetes mellitus was referred because of abdominal pain. On admission, she was alert but dehydrated with marked Kussmaul breathing. Blood glucose was 414 mg/dL (23 mmol/L). Blood gas analysis revealed severe metabolic acidosis (pH: 6.99) with an elevated anion gap (29.8 mmol/L) and an increased base excess (-25.2 mmol/L). At the sixth hour of treatment with intravenous fluids and insulin, the patient became delirious. The delirium persisted despite the normalization of the acidosis and became difficult to manage. Brain imaging studies revealed neither brain edema nor other intracranial pathology. No evidence of intoxication could be found. The patient gradually regained consciousness and was diagnosed as a case of severe diabetic ketoacidosis (DKA) associated with infection. We were unable to find a similar case in the pediatric literature and thought that reporting this unusual case would be a contribution to the literature on DKA in children.

Abstract
OBJECTIVE Existing factor analytic studies of symptoms of delirium are mostly based on small numbers of patients from specialized settings. This study thus sought to examine the factor structure of symptoms of delirium in a reasonably large sample of untreated patients referred to liaison psychiatric services of a multi-specialty hospital in north India, employing the more commonly used Delirium Rating Scale-Revised Version-1998 (DRS-R-98). METHOD Patients (n=151) who met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria for delirium were assessed with the DRS-R-98 prior to starting treatment with psychotropics. A principal component analysis was carried out to determine the factor structure of the symptoms based on these ratings. RESULTS Unlike previous efforts, patients of this study were relatively younger (mean age 47 years), with mainly hyperactive delirium, and did not have comorbid dementia. Three factors which together explained 47.32 % of variance of symptoms were identified. A "global cognitive" factor including disturbances of orientation, attention, short- and long-term memory, and visuospatial ability accounted for 18.33% of the variance. A "sleep and motor symptoms" factor consisting of sleep-wake cycle disturbances; delusions; and perceptual disturbances including hallucinations, motor-agitation, inverse of motor-retardation, and affect-lability accounted for 16% of the variance. A "thought and language" factor comprising abnormalities in language and thought process, temporal onset, and fluctuation of symptoms explained 13% of the variance. CONCLUSIONS Thus, the current factor analysis not only confirmed the presence of three principal symptom dimensions of delirium (found in several previous studies) but also extended these findings to a broader group of patients usually referred to liaison psychiatric services.

Phenytoin-induced visual disturbances mimicking Delirium Tremens in a child. Eur J Paediatr Neurol 2010; 14:460-3.

Abstract
Delirium Tremens is quite rare in children and it is usually caused by withdrawal or abstinence from alcohol, barbiturates and other major tranquilizers. The usual symptoms of Delirium Tremens include severe altered mental status with confusion, delusions, hallucinations, and severe agitation. Although psychosis is a recognized manifestation of Phenytoin toxicity, visual hallucinations are not. This study reports the case of a 4-year-old male with febrile seizures plus syndrome who developed acute complex visual hallucinations and psychomotor agitation early after therapy with intravenous Phenytoin was administered. These visual hallucinations mimicked those linked to Delirium Tremens and were not associated with an encephalopathy or other known neuropsychiatric side effects of this drug. Moreover, the hallucinations occurred while serum Phenytoin concentrations were below therapeutic range. We made an extensive investigation in order to exclude a non-convulsive Status Epilepticus, a Central Nervous System infection, a metabolic disorder, an underlying psychiatric disease and a possible drug toxicity. The temporal relationship between initiation of Phenytoin and onset of visual hallucinations and resolution of symptoms with withdrawal of Phenytoin suggests that the visual disturbances were probably due to that antiepileptic drug.

Abstract
Delirium, though quite often referred to psychiatrists for management, does not find many takers for analysis, research and publications. Acute in onset, multiplicity of etiology and manifestations, high risk of mortality delirium is very rewarding in proper management and outcome. Delirium has a limited agenda on teaching programs, research protocols and therapeutic strategies. There is a dearth of Indian studies both in international and national scientific literature. This annotation is based on a Medline search for "delirium India" on Pubmed, which resulted in 54 articles. A search in Indian Journal of Psychiatry for "delirium" resulted in 38 published articles, "delirium tremens" showed up only five articles. The articles are primarily from the Indian Journal of Psychiatry with cross reference to articles on Pubmed or Google search on Indian studies and a few international studies.
