Childhood gratification syndrome: Demystifying the clinical conundrum with a narrative literature review of the past 5 decades.

Background: Childhood gratification syndrome (CGS) refers to self-stimulatory or masturbatory behaviors in children, which may have an onset as early as in infancy (IGS). Aim: The aim of this review is to understand the various clinical manifestations of CGS/IGS and their clinical differentiation from commonly misdiagnosed neurological and physical illnesses and to formulate a preliminary approach to their diagnosis and management. Methods: This narrative review is based on a search of literature over the past 50 years (1972-2022) in three online databases (PubMed/Medline, Embase, and Google Scholar). Results: The behaviors are episodic, occurring for brief periods, involving posturing, stereotypical limb movements, pubic pressure with autonomic hyperactivity, and postepisodic lethargy. They mimic seizures, movement disorders, abdominal pain, and tics. The paper also highlights the gap in the current knowledge to guide future research in the area. CGS usually represents nonpathological "pleasure-seeking" habits of childhood, but at times, it may become problematic for the child and his family. A careful history and videotape analysis of the events confirms the diagnosis and behavioral therapy with parental reassurance as the mainstay of treatment. Conclusion: A better understanding and clinical awareness of the CGS are necessary to prevent misdiagnosis and delay in appropriate intervention.

Description of Nomophobia Among College Students: An Interpretative Phenomenological Analysis.

Background: Nomophobia is a situational phobia evoked by unavailability of smart phone or the thought of the possibility of not having it, not being able to use it and losing it. Currently used instruments for assessment of severity of nomophobia offers challenges of administration and have limited applicability in the Indian setting. Therefore, this study was aimed to depict and understand the lived experience of college students with nomophobia and making sense of it. Methods: This interpretative phenomenological analysis research design study was carried out on 17 undergraduate students belonging to different academic streams including Science, Social science and Commerce from the three study sites situated in different locations of India. An in-depth interview guide was prepared. The students who scored more than 90 on nomophobia questionnaire (NMP-Q Questionnaire) were included in the study. The data was recorded in audio and video format, it was transcribed, and translated from Hindi to English language. Coding was done and the theme were extracted. Results: The findings identified six superordinate themes: Digital Obsession, Digital Compulsion, Approval Motivation, Digital Intensement, Digital Well-being and Insight. Conclusion: The lived experiences of the students with nomophobia had explicitly shown a strong inclination towards the smartphone. They also focused on some of the significant aids provided by the smartphone. Further the intensive use of the smartphone was posing major challenges to the students when they were away from it.

Pharmacological interventions for antipsychotic-induced weight gain in schizophrenia: A network meta-analysis.

OBJECTIVE: Antipsychotic-induced weight gain (AIWG) is a significant but frequently neglected adverse effect of first- and second-generation antipsychotic therapy, which may lead to cardiovascular disturbances. The present network meta-analysis (NMA) was conducted to evaluate and compare the effects of available treatment options in antipsychotic-induced weight gain (AIWG). METHODS: The data was extracted from 68 relevant clinical trials after a literature search on MEDLINE/PubMed, Embase, Scopus, Cochrane databases and clinical trial registries. Random-effects Bayesian NMA was done to pool the effects across the interventions for the change in body weight from baseline. A network graph was built, a consistency model was run, node split analysis was performed, treatments were ranked as per the SUCRA score and meta-regression was done for the duration of therapy, baseline body weight and treatment strategy as the predictor variables. Finally, the results were sorted based on the certainty of evidence. RESULTS: The drugs showing significant reduction in body weight in order of magnitude of effect size include sibutramine 10 mg (-8.0 kg; -16. to -0.21), metformin 750 mg + lifestyle modification (-7.5 kg; -12 to -2.8), topiramate 200 mg (-7 kg; -10 to -3.4), metformin 750 mg (-5.7 kg; -9.3 to -2.1), topiramate 100 mg (-5.7 kg; -8.8 to -2.5), topiramate 50 mg (-5.2 kg; -10 to -0.57), liraglutide 1.8 mg (-5.2 kg; -10., -0.080), sibutramine 15 mg (-4.5 kg; -8.9 to -0.59), nizatidine 300 mg (-3.0 kg; -5.9 to -0.23) and metformin 1000 mg (-2.3 kg; -4.6 to -0.0046). There was no effect of duration of follow-up, baseline body weight and, preventive versus therapeutic strategy on weight reduction in AIWG. CONCLUSION: Metformin 750 mg with lifestyle modification was the most effective treatment for AIWG, followed by topiramate 200 mg, metformin 750 mg, and topiramate 100 mg with moderate certainty of evidence.

Total valproate versus free valproate in therapeutic drug monitoring for bipolar disorder: A cross-sectional study.

INTRODUCTION: The debate about observing total versus free serum valproate levels for therapeutic drug monitoring (TDM) has been unresolved for decades. This study was planned to assess the agreement between the total versus free valproate levels and the advantage of one method over the other in TDM. METHODS: The present cross-sectional study was done on 93 patients with bipolar disorder. The intraclass correlation coefficient, Bland Altman analysis, and Lin's concordance analysis were done to assess the agreement between the total and free valproate concentrations. Linear and polynomial models were constructed to evaluate the relation between the two measurements. Receiver operating characteristics analysis was done to compare the accuracy for differentiating remission from non-remission on Young's mania rating scale (YMRS). RESULTS: The intraclass correlation coefficient and Lin's concordance correlation coefficient were 0.491 (p = .002) and 0.055 (95% CI:0.037, 0.073), respectively. Bland Altman's analysis showed proportional bias. A polynomial model of second order was found to be the best fit for the prediction of free valproate from the data for total valproate, and 81.4% of the variability in free valproate could be explained when adjusted for albumin levels. The area under the curve for total valproate was 0.60 when compared to free valproate 0.56 for differentiating between remission and non-remission, but the comparison between the two ROC analyses was not statistically significant. CONCLUSION: Free valproate does not provide any added advantage over the total valproate levels; hence, total valproate levels may continue to be used as the marker for drug monitoring.

Augmentation Strategies for Partial or Non-responders to Clozapine in Patients with Schizophrenia: A Bayesian Network Meta-analysis of Randomized Controlled Trials.

Clozapine is the only approved drug for treatment-resistant schizophrenia, but the response to the drug is often inadequate. Augmentation with other antipsychotics, anticonvulsants, and antidepressants is recommended for such patients, but there is a lack of evidence regarding the most effective therapy. This network meta-analysis was conducted to evaluate the efficacy of pharmacological agents used in the augmentation strategies in patients who were partial/ non-responders to clozapine. Relevant data were extracted from 30 randomized controlled trials through searches of electronic databases (MEDLINE/PubMed, Embase, Cochrane, clinical trial registries). PRISMA guidelines were followed for the extraction, management, analysis, and reporting of the data. The outcome measure in this study was a reduction in symptom severity according to total PANSS/BPRS and was reported as the standardized mean difference with a 95% credible interval. Bayesian network meta-analysis with random effects model and uninformative priors was conducted, and the ranking probability of each intervention was done. Meta-regression was done to assess the effect of duration on the reduction in symptom severity scores. Mirtazapine (-5.2 [95%CrI: -7.7, -2.7]) and memantine (-2.1 [95%CrI: -4.0, -0.19]] were more efficacious than placebo for augmentation of clozapine in partial/non-responders and were the most effective adjunctive agents as per SUCRA scores. Both drugs did not cause a significant increase in frequency of adverse events compared to placebo. There was a significant effect of duration on the reduction in symptom severity. There was no evident publication bias. Mirtazapine and memantine may prove beneficial for augmentation of clozapine in non/partial responders to monotherapy.

Efficacy and safety of low-dose amisulpride versus olanzapine-fluoxetine combination in post-schizophrenic depression: A randomized controlled trial.

Post-schizophrenic depression (PSD) increases the morbidity, mortality, and health burden in patients with schizophrenia. However, treatment of PSD is challenging due to the lack of substantial evidence of standard clinical practice. This study was aimed at comparing the efficacy and safety of low-dose amisulpride versus olanzapine-fluoxetine combination (OFC) in PSD. This was a randomized controlled trial conducted in sixty patients with PSD fulfilling the eligibility criteria. Recruited patients were randomized to receive either amisulpride at low dose (i.e., 100-300 mg/day) or OFC (5/10 mg + 20 mg) for eight weeks. The Calgary Depression Scale for Schizophrenia (CDSS), the Clinical Global Impression-Severity (CGI-S) and serum BDNF levels were assessed at baseline and after eight weeks of treatment. The change in the CDSS scores from baseline over eight weeks was significant in both the amisulpride and OFC groups. However, the changes were not significant when compared between the groups. Similarly, the changes in CGI-S scores and serum BDNF levels were significant in each group; but non-significant between the groups. A significant negative correlation was found between the changes in the CDSS scores and the serum BDNF levels in each group. No significant adverse events were noted in either group. Thus, to conclude, low-dose amisulpride can be a potential monotherapy in PSD with a favourable clinical outcome and safety profile (ClinicalTrials.gov ID: NCT04876521).

Acute REM sleep behaviour disorder associated with alcohol withdrawal: A case report and literature review.

INTRODUCTION: Rapid eye movement (REM) sleep behaviour disorder (RBD) is a parasomnia characterised by the loss of REM sleep muscle atonia and the enactment of dreams. Acute RBD associated with alcohol withdrawal syndrome is known, but the studies are limited, particularly on its neurobiological underpinnings and management alongside the withdrawal state. This work attempts to address this using a case study and relevant literature review. CASE PRESENTATION: A 40-year-old male with alcohol dependence (for 20 years) reported new-onset terrifying nightmares and violent behaviours in his sleep precipitated by alcohol withdrawal states for the last 18 months. The polysomnographic finding of REM-without-atonia supported the diagnosis of RBD. He was treated with chlordiazepoxide 100 mg/day (gradually tapered and stopped) and thiamine supplements. Post-discharge, he remained abstinent and symptom-free during the three months of follow-up. DISCUSSION: RBD related to alcohol withdrawal syndrome has been previously described in a few anecdotal reports. Sudden withdrawal from central nervous system suppressants like alcohol is hypothesised to cause a homeostatic imbalance in gamma-aminobutyric acid (GABA) pathways and 'REM rebound', resulting in the clinical and polysomnographic picture of RBD. Benzodiazepines have been found to be useful in both RBD and alcohol withdrawal. CONCLUSIONS: Alcohol withdrawal syndrome may present with acute RBD, which can be treated with a short course of benzodiazepine. However, further studies are needed to explore the long-term course of RBD in these patients.

Efficacy of pharmacological agents for the management of treatment-resistant schizophrenia: a network meta-analysis.

OBJECTIVE: The present network meta-analysis (NMA) was conducted to compare and generate evidence for the most efficacious treatment among available pharmacological interventions for treatment-resistant schizophrenia (TRS). METHODS: Reviewers extracted data from 47 studies screened from PubMed/MEDLINE, Embase, Cochrane databases and clinical trial registries fulfilling the eligibility criteria. Random effects Bayesian NMA was done with non-informative priors. Network geometry was visualized, and node splitting was done for the closed triangles. Standardized mean difference and 95% credible interval(95%CrI) were reported for the reduction in symptom severity scores. The probability of each intervention for each rank was plotted. Meta-regression was done for the duration of the therapy. RESULTS: Augmentation of antipsychotics with escitalopram (SMD: -1.7[95%CrI: -2.8, -0.70]), glycine (SMD: -1.2 [95%CrI: -2.2, -0.28]) and Yokukansan (SMD: -1.3 [95%CrI: -2.4, -0.24]) shows a statistically significant reduction in symptom severity when compared to clozapine. As per surface under cumulative ranking curve analysis, escitalopram in combination with antipsychotics appeared to be the best intervention with moderate certainty of evidence. There was no significant effect of the duration of therapy on the treatment effects. CONCLUSION: Escitalopram augmentation of antipsychotics appears to be the most efficacious treatment with moderate certainty of evidence among the available pharmacological interventions.
