Parasomnia induced by lemborexant: a case report.

Lemborexant, an orexin receptor antagonist, is effective not only for sleep disorders but also for preventing and treating delirium. To date, no complex sleep-related behaviors due to lemborexant have been reported. Herein, we present the case of a 69-year-old male patient who was hospitalized for oral floor and tongue cancer and developed delirium after surgery; however, upon lemborexant dosage increase, used to treat insomnia, he developed abnormal nocturnal behavior. This symptom rapidly improved when lemborexant was discontinued. Distinguishing parasomnia from delirium is important because the treatment of these two conditions differs. Although rapid eye movement sleep behavior or sleepwalking was the cause of this parasomnia, a definitive diagnosis could not be established. If qualitatively distinct abnormal behavior is observed compared to delirium after increasing lemborexant dosage, the possibility of parasomnia should be considered.

Actual conditions for returning home after hospitalization among older patients receiving home medical care in Japan: OHCARE Study.

AIM: To examine the actual conditions of older patients receiving home medical care after hospitalization over a period of 2 years in Japan. METHODS: The study population included 102 participants, aged ≥65 years, receiving home medical care, who consented to participate in the Osaka Home Care Registry (OHCARE) study in Japan over a period of 2 years. We investigated the actual conditions for returning home after hospitalization. RESULTS: The median age of the 102 participants was 84 years, and 61 (59.8%) were women. In the group that returned home, 42 (55.3%) of the respondents desired to recuperate in a familiar place, as in advanced care planning (ACP). During the 2-year follow-up period, the group that did not return home had significantly more deaths. A multivariate analysis showed the association in the presence of ACP (odds ratio: 4.72, 95% confidence interval: 1.60-13.86) and cardiac disease (odds ratio: 0.25, 95% confidence interval: 0.08-0.76). The lack of ACP in the medical records when the patient was admitted to the hospital may have prevented the return home. CONCLUSION: In older patients who had difficulty returning home after hospitalization, the lack of ACP in home medical care may have been an influencing factor. ACP could help continue with home medical care. Geriatr Gerontol Int 2024; 24: 320-326.

Clinical Features of Quail Egg Ingestion in Patients with Acquired Tolerance to Hen Eggs: A Case Series Study.

INTRODUCTION: Patients with hen's egg allergy are often instructed to avoid consuming other avian eggs, such as quail eggs. However, it is unclear whether patients with an acquired tolerance to hen eggs continue to avoid consuming quail eggs. This study aimed to evaluate the clinical features of quail egg ingestion. METHODS: This prospective case series included children aged ≥1 year with hen's egg allergy who were recruited between October 2019 and February 2021 in our hospital. We conducted an oral food challenge (OFC) with three boiled quail eggs to evaluate the clinical features of quail egg ingestion in patients with acquired tolerance to hen eggs. The primary outcome was a positive OFC after ingesting three quail eggs. Secondary outcomes were cross-antigenicity between hen and quail eggs observed through the skin prick test (SPT) and pattern of quail egg allergy, comprising the onset of reaction, and severity. The correlation between the diameters of the wheals with SPT in hen and quail eggs was evaluated using the Pearson product-moment correlation coefficient. RESULTS: A total of 62 patients underwent the quail egg OFC. The median (interquartile range) age of the participants was 3 (2-5) years. Thirty-three (53%) patients had a history of anaphylaxis due to hen eggs. The median total immunoglobulin E (IgE) level in patients who underwent the OFC with half a heated whole hen's egg was 271 (98-593) IU/mL. The median specific IgE level in egg white and ovomucoid was 9.7 (3.2-21.5) and 4.4 (1.3-6.9) UA/mL, respectively. The quail egg OFC results revealed that none of the 59 patients who ate the three quail eggs completely had an allergic reaction. The SPT-positive and SPT-negative rates in raw and boiled hen and quail egg whites were both correlated. The diameters of wheals with SPT in raw hen and quail egg whites and yolks were positively correlated. CONCLUSION: Patients with an acquired tolerance to hen eggs may not be required to avoid consuming quail eggs.

Association between Children's Difficulties, Parent-Child Sleep, Parental Control, and Children's Screen Time: A Cross-Sectional Study in Japan.

Children's screen time may affect their growth and development. However, differences in the impact of various psychiatric and psychological factors on children's screen time is a research gap. This study aimed to explore the differences in the influence of related factors affecting children's screen time based on their sleep, difficulties, and parental control among Japanese elementary and junior high school students. A cross-sectional survey was conducted among parents in Japan. Data on screen time duration, parent-child background, strengths and difficulties, sleep variables, and parental control types were collected from 225 households. A regression analysis revealed that high Strengths and Difficulties Questionnaire (SDQ) scores (ß = 0.166, p = 0.008), sleep duration (ß = -0.281, p < 0.001), and parental control (ß = -0.204, p = 0.001) were significantly related to children's screen time. Additionally, it was found that parents' late bedtimes affect children's screen time by mediating children's sleep duration. This study, together with previous research, provides comprehensive insights into design interventions to decrease the screen time of children in the Japanese context.

Optimal period for achieving sustained unresponsiveness in peanut oral immunotherapy.

Background: Oral immunotherapy (OIT) can help children with persistent food allergies achieve sustained unresponsiveness (SU). However, the optimal therapeutic period for obtaining SU remains unclear. Objective: We aimed to retrospectively investigate the association between the OIT treatment period and achievement of SU. Methods: We enrolled patients who received OIT for peanut allergy between January 1, 2018 and December 31, 2022. OIT comprised the build-up phase, maintenance phase, complete avoidance, and an oral food challenge (OFC) for confirming SU. The peanut dose in the OFC was gradually increased to 3,000 mg (peanut protein: 795 mg), which was subsequently maintained for ≥5 months. SU was defined as a negative response to 795 mg of peanut protein after ≥2 weeks of complete avoidance. We evaluated the therapeutic OIT period for achieving SU using Kaplan-Meier analysis. Results: Forty-eight patients underwent peanut OIT. The starting age at OIT initiation was 8 (interquartile range [IQR], 7-10) years. Forty-one (85%) patients had a history of anaphylaxis. The median specific immunoglobulin E concentration to peanut and Ara h 2 at OIT initiation was 85.3 (IQR, 33.7-100) and 57.6 (IQR, 21.9-100) UA/mL, respectively. The median observational period was 2.1 (IQR, 1.6-3.0) person-years (PY). Thirty-four (71%) patients achieved SU, with the rate of SU achievement gradually increasing with the therapeutic period. The median period until SU achievement was 2.1 (95% confidence interval, 1.6-2.5) PY. The rate of SU achievement slowed down after 2.7 PY. Conclusion: OIT for at least 2.7 PY can increase the rate of SU achievement. The protocol No. 3107.

Effect of education regarding treatment guidelines for schizophrenia and depression on the treatment behavior of psychiatrists: A multicenter study.

AIM: This study aims to examine the real-world effectiveness of education regarding clinical guidelines for psychiatric disorders using 'the Effectiveness of guidelines for dissemination and education in psychiatric treatment (EGUIDE)' project. METHODS: The EGUIDE project is a nationwide prospective implementation study of two clinical practice guidelines, i.e., the Guideline for Pharmacological Therapy of Schizophrenia and the Treatment Guidelines for Major Depressive Disorders, in Japan. Between 2016 and 2019, 782 psychiatrists belonging to 176 hospitals with psychiatric wards participated in the project and attended lectures on clinical practice guidelines. The proportions of guideline-recommended treatments in 7405 patients with schizophrenia and 3794 patients with major depressive disorder at participating hospitals were compared between patients under the care of psychiatrists participating in the project and those not participating in the project. Clinical and prescribing data on the patients discharged from April to September each year from participating hospitals of the project were also analyzed. RESULTS: The proportions of three quality indicators (antipsychotic monotherapy regardless of whether other psychotropics medication, antipsychotic monotherapy without other psychotropics and no prescription of anxiolytics or hypnotics) for schizophrenia were higher among participating psychiatrists than among nonparticipating psychiatrists. As similar results were obtained in major depressive disorder, the effectiveness of the project for the dissemination of guideline-recommended treatment has been replicated. CONCLUSION: This strategy of providing education regarding the clinical guidelines for psychiatric disorders was effective in improving the treatment-related behavior of psychiatrists. The use of this education-based strategy might contribute to resolving the mental health treatment gap.

Connective differences between patients with depression with and without ASD: A case-control study.

BACKGROUND: Researchers find it difficult to distinguish between depression with ASD (Depress-wASD) and without ASD (Depression) in adult patients. We aimed to clarify the differences in brain connectivity between patients with depression with ASD and without ASD. METHODS: From April 2017 to February 2019, 22 patients with suspected depression were admitted to the hospital for diagnosis or follow-up and met the inclusion criteria. The diagnosis was determined according to the Diagnostic and Statistical Manual of Mental Disorders-5 by skilled psychiatrists. The Hamilton Depression Rating Scale (HAM-D), Young Mania Raging Scale (YMRS), Mini-International Neuropsychiatric Interview, Parent-interview ASD Rating Scale-Text Revision (PARS-TR), and Autism-Spectrum Quotient-Japanese version (AQ-J) were used to assess the patients' background and help with diagnosis. Resting-state functional magnetic resonance imaging (rs-fMRI) was performed using the 3-T-MRI system. rs-fMRI was processed using the CONN functional connectivity toolbox. Voxel-based morphometry was performed using structural images. RESULTS: No significant difference was observed between the Depress-wASD and Depression groups using the HAM-D, YMRS, AQ-J, Intelligence Quotient (IQ), and verbal IQ results. rs-fMRI for the Depress-wASD group indicated a positive connection between the salience network (SN) and right supramarginal gyrus (SMG) and a negative connection between the SN and hippocampus and para-hippocampus than that for the Depression group. No significant structural differences were observed between the groups. CONCLUSIONS: We identified differences in the SN involving the SMG and hippocampal regions between the Depress-wASD and Depression groups.

Orexin receptor antagonists versus antipsychotics for the management of delirium in intensive care unit patients with cardiovascular disease: A retrospective observational study.

OBJECTIVE: Although antipsychotics are often used in the pharmacological treatment of delirium, recent reports suggest the efficacy of orexin receptor antagonists. This study investigated whether orexin receptor antagonists could be a possible treatment option for delirium. METHOD: A nonblinded nonrandomized routine clinical treatment was performed. Patients treated in intensive care units (ICU) for cardiovascular disease and receiving psychiatric intervention were studied retrospectively. The scores from the Intensive Care Delirium Screening Checklist (ICDSC) were compared between patients treated with orexin receptor antagonists and those treated with antipsychotics. RESULTS: The mean (standard deviation) ICDSC scores were 4.5 (1.8) at day -1 and 2.6 (2.6) at day 7 for orexin receptor antagonist group (n = 25) and 4.6 (2.4) at day -1 and 4.1 (2.2) at day 7 for antipsychotic group (n = 28). The orexin receptor antagonist group showed significantly lower ICDSC scores than the antipsychotic group (p = 0.021). CONCLUSION: While precise efficacy cannot be determined from our retrospective, observational, and uncontrolled pilot study, this analysis encourages a future double-blind randomized placebo-controlled trial of orexin-antagonists for delirium treatment.

Change of prescription for patients with schizophrenia or major depressive disorder during admission: real-world prescribing surveys from the effectiveness of guidelines for dissemination and education psychiatric treatment project.

BACKGROUND: Polypharmacy of additional psychotropics alongside the main treatment drug (antipsychotics in schizophrenia and antidepressants in major depressive disorder) is common in Japan. Our goal is to align psychotropic prescription in Japan with international standards, while reducing the differences between facilities. To achieve this goal, we aimed to compare prescriptions at the time of hospital admission and discharge. METHODS: Data on prescriptions at admission and discharge from 2016 to 2020 were collected. We divided the patients into four groups: (1) mono_mono group, monotherapy of the main drug at admission and discharge; (2) mono_poly group, monotherapy at admission and polypharmacy at discharge; (3) poly_poly group, polypharmacy at admission and discharge; and (4) poly_mono group, polypharmacy at admission and monotherapy at discharge. We compared the changes in dosage and number of psychotropics among the four groups. RESULTS: For both schizophrenia and major depressive disorder, the patients who received monotherapy with the main drug at admission were likely to receive main drug monotherapy at discharge and vice versa. For schizophrenia, the polypharmacy was prescribed more often in the mono_poly group than that in the mono_mono group. The prescription was not changed at all for more than 10% of the patients. CONCLUSIONS: It is critical to avoid a polypharmacy regimen to ensure that guideline-compliant treatment is provided. We expect higher rates of monotherapy with the main drug after the EGUIDE lectures. TRIAL REGISTRATION: The study protocol was registered in the University Hospital Medical Information Network Registry (UMIN000022645).

Cerebellar network changes in depressed patients with and without autism spectrum disorder: A case-control study.

Pathophysiological difference of depression in patients with and without autistic spectrum disorder (ASD) has not been investigated previously. Therefore, we sought to determine whether there were differences between non-ASD and ASD groups on resting-state functional magnetic resonance imaging (rs-fMRI) in patients with depression. We performed 3T MRI under resting state in 8 patients with depression and ASD and 12 patients with depression but without ASD. The ASD group showed increased functional connectivity in the cerebellar network of the left posterior inferior temporal gyrus and anterior cerebellar lobes compared to the non-ASD group in an analysis of covariance. Adding antipsychotics, antidepressants, benzodiazepines, nonbenzodiazepines, anxiolytics, hypnotics, or age as covariates showed a similar increase in functional connectivity. Thus, this study found that depressive patients with ASD had increased functional connectivity in the cerebellar network. Our findings suggest that fMRI may be able to evaluate differences in depressed patients with and without ASD.

Effects of electroconvulsive therapy on the use of anxiolytics and sleep medications: a propensity score-matched analysis.

AIM: We investigated the association of electroconvulsive therapy (ECT) with anxiolytic and sleep medication use in patients with major depressive disorder (MDD) and schizophrenia (SZ). METHODS: This nationwide observational study analyzed data from 3483 MDD inpatients and 6663 SZ inpatients. Patients with MDD and SZ were classified into those who underwent ECT during hospitalization and those who did not. A propensity score-matching method was performed to adjust for preadmission characteristics and clinical information, which were expected bias between the two groups. Rates of anxiolytic and sleep medication use at discharge were compared in the matched sample. RESULTS: 500 MDD patients were assigned to both groups. In the matched MDD sample, the rate of anxiolytic and sleep medication use at discharge was significantly lower in the ECT group than in the non-ECT group (64.9% vs. 75.8%, P = 1.7 × 10-4 ). In the ECT group, the rate of anxiolytic and sleep medication use at discharge was significantly lower than that prior to admission (64.9% vs. 73.2%, P = 1.2 × 10-14 ). 390 SZ patients were allocated. In the matched SZ sample, the ECT group was not significantly different from the non-ECT group in the rate of anxiolytics and sleep medications use at discharge (61.3% vs. 68.2%, P = 4.3 × 10-2 ). In the ECT group, the rate of anxiolytics and sleep medications use at discharge was significantly lower than that before admission (61.3% vs. 70.5%, P = 4.4 × 10-4 ), although this was not the primary outcome. CONCLUSION: Reduction of anxiolytic and sleep medication use may be considered positively when ECT is indicated for treatment of MDD.

Development of an individual fitness score (IFS) based on the depression treatment guidelines of in the Japanese Society of Mood Disorders.

AIM: Treatment guidelines are designed to assist patients and health care providers and are used as tools for making treatment decisions in clinical situations. The treatment guidelines of the Japanese Society of Mood Disorders establish treatment recommendations for each severity of depression. The individual fitness score (IFS) was developed as a simple and objective indicator to assess whether individual patients are practicing treatment by the recommendations of the depression treatment guidelines of the Japanese Society of Mood Disorders. METHODS: The EGUIDE project members determined the IFS through the modified Delphi method. In this article, the IFS was calculated based on the treatment of depressed patients treated and discharged between 2016 and 2020 at facilities participating in the EGUIDE project. In addition, we compared scores at admission and discharge. RESULTS: The study included 428 depressed patients (mild n = 22, moderate/severe n = 331, psychotic n = 75) at 57 facilities. The mean IFS scores by severity were statistically significantly higher at discharge than at admission with moderate/severe depression (mild 36.1 ± 34.2 vs. 41.6 ± 36.9, p = 0.49; moderate/severe 50.2 ± 33.6 vs. 55.7 ± 32.6, p = 2.1 × 10-3; psychotic 47.4 ± 32.9 versus 52.9 ± 36.0, p = 0.23). CONCLUSION: We developed the IFS based on the depression treatment guideline, which enables us to objectively determine how close the treatment is to the guideline at the time of evaluation in individual cases. Therefore, the IFS may influence guideline-oriented treatment behavior and lead to the equalization of depression treatment in Japan, including pharmacotherapy.

Outcomes of an interdisciplinary return to work intervention including occupational therapy for mood and adjustment disorders: A single-arm clinical trial.

BACKGROUND: Mood and adjustment disorders are two major causes of long-term sick leave among employees, leading to large social losses. Therefore, a return to work (RTW) intervention was attempted, targeting patients with mood and adjustment disorders. OBJECTIVE: This study aimed to investigate the outcome of an interdisciplinary RTW intervention including occupational therapy implemented within the Japanese healthcare framework. METHODS: An interdisciplinary RTW intervention including occupational therapy was conducted five times a week for approximately three months, targeting individuals with mood and adjustment disorders who took a leave of absence. Their mental symptoms, cognitive functioning, job performance, temperament, social adaptation, psychosocial state, and readiness to RTW before and after the intervention were evaluated. Full-time RTW ratios at 3, 6, 12, 18, and 24 months from baseline were followed up and compared with those of prior studies. RESULTS: A total of 30 individuals completed the intervention. After the intervention, participants' psychological symptoms, cognitive function, vocational aptitude, temperament, social adaptation, psychosocial state, and readiness to RTW improved (p≤0.001-0.0279). The ratios of RTW at 3, 6, 12, 18, and 24 months from the baseline were 6.7%, 46.7%, 73.3%, 77.8%, and 82.6%, respectively, reflecting a higher pattern than prior reports. CONCLUSIONS: The interdisciplinary RTW intervention including occupational therapy has the potential to improve not only depressive symptoms but also cognitive functioning, job performance, social adaptation, and readiness to RTW. They can also raise RTW ratios.

Improvement of catatonia-induced rapid respiratory failure with electroconvulsive therapy: A case report.

We encountered a case of sudden respiratory failure during treatment of catatonia that required intensive care. Electroconvulsive therapy (ECT) was administered in the intensive care unit while the patient was under systemic control. The catatonia symptom was relieved, and respiratory failure improved. Although a proximal venous thrombus was observed, anticoagulation therapy was continued during ECT, and the patient was successfully treated without causing a pulmonary embolism. It is crucial to monitor the patient's physical and psychological symptoms because respiratory status may deteriorate rapidly in a catatonic state.

Risk Factors for Lung Function Decline in Pediatric Asthma under Treatment: A Retrospective, Multicenter, Observational Study.

Background: Childhood asthma is a major risk for low lung function in later adulthood, but what factors in asthma are associated with the poor lung function during childhood is not known. Objective: To identify clinical factors in children with asthma associated with low or declining lung function during the treatment. Methods: We enrolled children with asthma who had been treated throughout three age periods, i.e., 6−9, 10−12, and 13−15 years old, at seven specialized hospitals in Japan. Clinical information and lung function measurements were retrieved from the electronic chart systems. To characterize the lung function trajectories during each age period, we evaluated the forced expiratory volume 1 (FEV1) with % predicted values and individual changes by the slope (S) from linear regression. We defined four trajectory patterns: normal (Group N) and low (Group L), showing %FEV1 ≥80% or <80% throughout all three periods; upward (Group U) and downward (Group D), showing S ≥ 0 or S < 0%. Logistic regression analysis was performed to compare factors associated with the unfavorable (D/L) versus favorable (N/U) groups. Results: Among 273 eligible patients, 197 (72%) were classified into Group N (n = 150)/U (n = 47), while 76 (28%) were in Group D (n = 66)/L (n = 10). A history of poor asthma control, long-acting beta2 agonist use, and a lower height Z-score during 13−15 years were associated with an unfavorable outcome (Group D/L). Conversely, inhaled corticosteroid (ICS) use during 10−12 years and high-dose ICS use during 13−15 years were associated with a favorable outcome (Group N/U). Conclusion: We identified several factors that are associated with unfavorable lung function changes in pediatric asthma. Attention should be paid to the possible relationship between yearly changes in lung function and poor asthma control, use of ICS (and its dose) and use of LABA.

Characteristics of the treatments for each severity of major depressive disorder: A real-world multi-site study.

PURPOSE: In the treatment guidelines for major depressive disorder (MDD), the recommended treatment differs based on the severity. However, the type of treatment provided based on the severity of MDD in real-world clinical practice has not been investigated. In this study, we clarified the actual situation of MDD treatment in clinical practice and compared the treatment based on the severity of MDD. METHODS: We used data from 1484 patients with MDD at discharge from October 2016 to March 2020. RESULTS: The number of psychotropic prescriptions tended to be lower in those diagnosed with MDD in the severe group compared to in the non-severe group. There were significant differences among the three groups (mild, moderate/severe, and psychotic) in the percentage of patients who were not prescribed antipsychotics (p = 1.9 ×10-6), a combination of antipsychotics and antidepressants (p = 5.0 ×10-4), and the implementation rate of modified electroconvulsive therapy (m-ECT) (p = 3.4 ×10-9). The percentage of patients with a severe diagnosis who underwent m-ECT was higher, which corresponded to the severity. CONCLUSION: Our findings showed that the use of psychotropics decreased when the severity of MDD was diagnosed, and the rate of a combination of antipsychotics and antidepressants and the implementation rate of m-ECT increased with the severity. However, this study suggests that there is still an evidence-practice gap in the treatment of MDD in Japan, and guidelines are only partially adhered to in the treatment of depression.

A dissemination and education programme to improve the clinical behaviours of psychiatrists in accordance with treatment guidelines for schizophrenia and major depressive disorders: the Effectiveness of Guidelines for Dissemination and Education in Psychiatric Treatment (EGUIDE) project.

BACKGROUND: Clinical practice guidelines for schizophrenia and major depressive disorder have been published. However, these have not had sufficient penetration in clinical settings. We developed the Effectiveness of Guidelines for Dissemination and Education in Psychiatric Treatment (EGUIDE) project as a dissemination and education programme for psychiatrists. AIMS: The aim of this study is to assess the effectiveness of the EGUIDE project on the subjective clinical behaviour of psychiatrists in accordance with clinical practice guidelines before and 1 and 2 years after participation in the programmes. METHOD: A total of 607 psychiatrists participated in this study during October 2016 and March 2019. They attended both 1-day educational programmes based on the clinical practice guidelines for schizophrenia and major depressive disorder, and answered web questionnaires about their clinical behaviours before and 1 and 2 years after attending the programmes. We evaluated the changes in clinical behaviours in accordance with the clinical practice guidelines between before and 2 years after the programme. RESULTS: All of the scores for clinical behaviours in accordance with clinical practice guidelines were significantly improved after 1 and 2 years compared with before attending the programmes. There were no significant changes in any of the scores between 1 and 2 years after attending. CONCLUSIONS: All clinical behaviours in accordance with clinical practice guidelines improved after attending the EGUIDE programme, and were maintained for at least 2 years. The EGUIDE project could contribute to improved guideline-based clinical behaviour among psychiatrists.

Subjective assessment of participants in education programs on clinical practice guidelines in the field of psychiatry.

The Effectiveness of Guidelines for Dissemination and Education in psychiatric treatment (EGUIDE) project, which is a nationwide dissemination and implementation program for clinical practice guidelines (CPGs) in the field of psychiatry, is currently ongoing. In the current study, a subjective assessment of the participants in the EGUIDE programs was assessed using a questionnaire. Then, the relationships between the subjective assessment, the characteristics of the participants, and the clinical knowledge of the CPGs were evaluated. More than 90% of the participants gave a high rating for the components of content, recommendation, knowledge, skill, and adherence, but not for the component of confidence. A positive correlation was found between years of professional experience and the score of confidence. These results suggest that it may be necessary to apply the knowledge and skills of CPGs obtained in the education programs into practice to increase confidence in the proper use of psychiatric therapies based on CPGs.

Evaluation of early laryngeal reaction at oral food challenge.

Background: Open oral food challenge (OFC) is a commonly used diagnostic method for food allergy; however, the occurrence of uncertain reactions leads to inconclusive results. Objective: We aimed to determine the associations between mild laryngeal symptoms and positive results in open OFCs. Methods: We retrospectively investigated medical records of high-risk children (aged 3-15 years) who had undergone open OFC for a low dose of peanuts, hen's egg, cow's milk, or wheat. The OFC result, severity of allergic reactions, and administered treatments during OFCs were compared between the subjects with and without laryngeal symptoms. The risks of a positive OFC result were assessed by using logistic univariate and multivariate analyses, with age, sex, and serum levels of total and food-specific IgE as covariates. Results: Among the 198 patients who underwent OFC, 25 had mild laryngeal symptoms: 8 (32%), 7 (22%), 0 (0%), and 10 (40%) in the OFC trials with hen's egg, cow's milk, wheat, and peanuts, respectively. In the peanut OFCs, univariate analyses revealed a 5-fold higher risk of a positive result (odds ratio = 5.0 [95% CI = 1.1-22.8]) in the symptomatic subjects than in the asymptomatic subjects. However, on multivariate analyses, none of the associations between the symptoms and a positive result were significant in any of the OFCs. The occurrence of anaphylaxis and adrenalin injections did not differ significantly between the symptomatic and asymptomatic subjects. Conclusions: Laryngeal symptoms should be considered a warning sign for a positive OFC result in peanut OFCs, although not critical enough to stop the challenge.

Hypnotic medication use among inpatients with schizophrenia and major depressive disorder: results of a nationwide study.

STUDY OBJECTIVES: To investigate the proportion of inpatients with schizophrenia and major depressive disorder prescribed hypnotic medication, and the association between such medication and the use of other antipsychotic agents. METHODS: This was a nationwide cross-sectional study performed as part of the 'Effectiveness of Guidelines for Dissemination and Education in Psychiatric Treatment' (EGUIDE) project. Data from 2146 inpatients with schizophrenia and 1031 inpatients with major depressive disorder were analyzed. All types and dosages of psychotropic drugs were recorded and the data at the time of discharge were analyzed. Associations between the use of hypnotic medication and other antipsychotic agents were evaluated using multivariate logistic regression analyses. RESULTS: The proportions of schizophrenia patients who were prescribed any and two or more hypnotic agents were 55.7% and 17.6%, respectively, and the corresponding proportions for patients with major depressive disorder were 63.6% and 22.6%, respectively. In schizophrenia patients, multivariate logistic regression analyses showed that two or more antipsychotics, anticholinergic drugs, anxiolytics, and mood stabilizers/antiepileptic drugs were positively associated with the use of any hypnotic agent. In patients with major depressive disorder, multivariate logistic regression analyses revealed that two or more antidepressants, two or more antipsychotics, anxiolytics, and mood stabilizers/antiepileptic drugs were positively associated with the use of any hypnotic agent. CONCLUSIONS: Prescription of hypnotic agents was found to be highly frequent among inpatients with psychiatric disorders. Prescription of two or more main antipsychotic agents was commonly associated with the use of hypnotic medication for both schizophrenia and major depressive disorder.
