Depressive Symptoms and Their Associated Factors in Nursery School Teachers: A Multicenter Cross-Sectional Study.

Background Although nursery school teachers may experience depressive symptoms, there have been few studies exploring the associated factors. The objective of this study was to determine the prevalence of depression and explore its associated factors in nursery school teachers. Methods This cross-sectional study surveyed nursery school teachers in Sakyo-ku, Kyoto City to determine the prevalence of depressive symptoms as measured by the five-item Mental Health Inventory. We used a logistic regression model to assess the factors. Results Respondents were 148 teachers (36%) out of 410 nursery school teachers in 21 nursery schools, and 65 (44%) indicated that they had depressive symptoms. Using the Work Limitation Questionnaire (WLQ), productivity loss score (adjusted risk ratio [ARR], 1.17; 95% confidence interval [95% CI], 1.02 to 1.34) and psychological demands (ARR, 1.25; 95% CI, 1.02 to 1.53) were found to be associated with depressive symptoms. Conclusions The associated factors with depressive symptoms were high psychological demands and a high degree of presenteeism. Further prospective cohort studies with larger sample sizes should be conducted to confirm these relationships.

Introduction of precordial Doppler ultrasound to confirm correct peripheral venous access during general anesthesia in children: A preliminary study.

BACKGROUND: Delayed identification of infiltration and dysfunction of peripheral intravenous (PIV) access can lead to serious consequences during general anesthesia in children. This preliminary study aimed to describe the application of precordial Doppler ultrasound during general anesthesia in children to detect and confirm the correct PIV access and to evaluate the accuracy of this method. METHODS: This was a single-center, preliminary study that was conducted in children (<18 years) who were scheduled for elective surgeries between October 2019 and March 2020. Rater anesthesiologists judged the change in precordial Doppler sound (S test) before and after injection of 0.5 mL/kg of normal saline (NS) via PIV. Blood flow velocity before and after NS injection was recorded, and multiple cutoff points were set to analyze the accuracy of detecting the infiltration and dysfunction of PIV catheter (V test). RESULTS: The total incidence of peripheral infiltration and dysfunction of PIV catheter was 7/512 (1.4%). In the S test, the sensitivity, specificity, positive and negative likelihood ratios, and area under the receiver-operating characteristic curves (AUCs) were 5/7 (71.4%; 95% confidence interval [CI], 29.0%-96.3%), 490/505 (97.0%; 95% CI, 95.1%-98.3%), 24.0, 0.29, and 0.84, respectively. The V test showed that the reasonable threshold of blood flow velocity change was 1.0 m/s, with sensitivity, specificity, positive and negative likelihood ratios, and AUC of 4/7 (57.1%; 95% CI, 18.4%-90.1%), 489/505 (96.8%; 95% CI, 94.9%-98.2%), 18.0 and 0.44, and 0.84, respectively. CONCLUSIONS: This preliminary study demonstrated that precordial Doppler ultrasound is a feasible, easy-to-use, and noninvasive technique with good accuracy to confirm the correct PIV access during general anesthesia in children. However, its accuracy requires further evaluation.

Depression and anxiety correlate differently with salivary free cortisol in the morning in patients with functional somatic syndrome.

Patients presenting with functional somatic syndrome (FSS) are common, and the symptoms are persistent and difficult to treat for doctors and costly for society. The aim of this study was to clarify the common pathophysiology of FSS, especially the relationship between hypothalamic-pituitary-adrenal (HPA) axis function and psychological characteristics of patients with FSS. The subjects were 45 patients with FSS and 29 healthy controls. Salivary free cortisol was measured in the morning, and psychological tests examining depression, anxiety and quality of life (QOL) were performed on the same day. In patients with FSS, depressive scores showed a significant negative correlation with salivary free cortisol in the morning, although in healthy controls, cortisol showed a significant positive correlation with depressive scores. In addition, the correlation between other psychological test scores and cortisol secretion in patients with FSS contrasted with that of controls. The relationship between cortisol and depression, anxiety or QOL, suggests that the HPA axis of patients with FSS is dysfunctional and does not function properly when patients with FSS are under stress. This dysfunction may explain the pathology of medically unexplained persistent symptoms of patients with FSS.

Relationship among human herpesvirus 6 reactivation, serum interleukin 10 levels, and rash/graft-versus-host disease after allogeneic stem cell transplantation.

BACKGROUND: The relationship between herpesvirus reactivation and graft-versus-host disease (GVHD) after allogeneic stem cell transplantation (allo-SCT) is unclear. OBJECTIVE: We sought to examine the relationship between human herpesvirus (HHV) reactivation and rash/GVHD after allo-SCT by prospective evaluation. METHODS: Fifteen patients who had received allo-SCT underwent prospective serial examinations for human herpesvirus 6 (HHV-6), HHV-7, cytomegalovirus, and Epstein-Barr virus DNA in the blood by polymerase chain reaction and real-time polymerase chain reaction. Serum interferon gamma, interleukins 4 and 10, tumor necrosis factor alpha, and soluble interleukin 2 receptor (sIL-2R) were also measured. RESULTS: In 10 of 15 patients, macular/papular eruptions were seen after allo-SCT and GVHD was diagnosed. In 8 patients with rash, HHV-6 DNA levels correlated with the cutaneous manifestation. Interleukin 10 and sIL-2R also increased in association with rash. LIMITATIONS: The number of patients in our study was relatively small. Not all patients were examined for cytokines and sIL-2R. CONCLUSIONS: HHV-6 reactivation may be involved in the pathogenesis of rash/GVHD after allo-SCT.

Spread of Quadratus Lumborum Block to the Paravertebral Space Via Intramuscular Injection: A Volunteer Study.

BACKGROUND AND OBJECTIVES: Several types of quadratus lumborum block (QLB) are used for postoperative analgesia and are believed to be effective against both somatic and visceral pain via a local anesthetic (LA) effect in the paravertebral space (PVS). However, it remains unclear whether all QLB techniques result in LA spread into the PVS. We hypothesized that LA administered via intramuscular QLB would spread into the paravertebral space and investigated the spread and sensory block area of LA in intramuscular QLB. METHODS: This volunteer study included 5 healthy men and 1 woman, with no previous medical history. Intramuscular QLB and lateral transversus abdominis plane block were performed under real-time ultrasound guidance for comparison of sensory deprivation range. Two days later, the same procedure was performed on the contralateral side of the body. The spread of LA via intramuscular QLB spread to the PVS was assessed 1 hour after the first injections using magnetic resonance imaging. Sensory perception was also evaluated by the pinprick test at 90 minutes after injection. RESULTS: In total, we performed 11 intramuscular QLBs and 11 lateral transversus abdominis plane blocks. Magnetic resonance imaging showed that LA did not spread into the PVS after ultrasound-guided intramuscular QLB. The analgesic area corresponded to the side of the body that was ipsilateral to the block. CONCLUSIONS: Ultrasound-guided intramuscular QLBs are not clinically useful for procedures requiring LA spread into the PVS but do result in an ipsilateral analgesic effect in healthy volunteers. CLINICAL TRIAL REGISTRATION: This study was registered at University Hospital Medical Information Network Clinical Trials Registry, UMIN 000019149.

An exploratory study of subgrouping of patients with functional somatic syndrome based on the psychophysiological stress response: its relationship with moods and subjective variables.

OBJECTIVE: To study the characteristics and subjective estimations of subgroups of patients with functional somatic syndrome (FSS). A characteristic in patients with FSS was reportedly hyporeactivity in the psychophysiological stress response (PSR). METHODS: The PSR was measured in 59 FSS patients and 41 healthy controls. Autonomic lability scores (ALSs) of six psychophysiological measurements on PSR were calculated. Cluster analysis using the ALSs was performed in the FSS group. A discriminant analysis was also performed to identify the criterion of the subgrouping. Factor analysis scores of the six ALSs, and moods and subjective variables were compared between the subgroups. RESULTS: Cluster analysis divided the FSS patients into two clusters. Three groups (low-lability, high-lability, and control groups) were compared. All factor scores of autonomic lability significantly differed between the low- and high-lability groups, and between the low-lability and control groups. The mood scores were higher in the high-lability group than in the low-lability group. The duration of suffering was significantly longer in the high-lability group than in the low-lability group. The distributions of symptoms and diagnosis did not significantly differ between the subgroups. CONCLUSIONS: We have tentatively verified that there are two subgroups based on the autonomic lability among FSS patients, which were independent of the type of symptoms and diagnostic category. Autonomic lability is an important axis in the multiaxial diagnosis of FSS.

[Multiple myeloma of the IgD-lambda type invading CNS].

A 52-year-old woman was admitted to the gynecological department of our hospital on July 29, 2002 because of a right lower abdominal mass. She has been suffering from pain in the right leg and inguinal area for a month before coming to the hospital. She was found to have pancytopenia and high serum levels of LDH and IgD. A bone marrow examination showed 63.8% of plasma cells and serum immunoelectrophoresis showed M-protein of the IgD-lambda type. She was diagnosed as having multiple myeloma and transferred to our department. VAD therapy was started from August 22. Although the plasma cells in the bone marrow almost disappeared, the right lower abdominal mass remained and a new mass appeared on the right frontal chest wall after two courses of the treatment. Combination chemotherapy with vincristine, ranimustine, melphalan, and dexamethasone (ROAD) was started on November 1. This was followed with thalidomide and radiation therapy of the right inguinal region was added. On December 16th, she suddenly experienced speech disturbance, nausea and the disturbance of consciousness. Examination of her cerebrospinal fluid showed 368/microl mononuclear cells with 93% plasma cells. The plasma cells disappeared after the 6th intrathecal injection with MTX and prednisolone and the chemotherapy was resumed. One month later, CNS relapse was apparent followed by generalized spread of the tumor mass, and she died on March 17, 2003.

Biopsychosocial approaches to a patient with vomiting of 10 years' duration--a case of temporal lobe epilepsy.

BACKGROUND: Vomiting is commonly encountered in clinical medicine. When organic gastrointestinal, metabolic, and brain diseases are ruled out, many cases are considered to be functional. We experienced an adult patient with epilepsy whose main symptom was vomiting. Biopsychosocial approaches were needed to control the symptoms. CASE PRESENTATION: A 26-year-old female with a 10-year history of persistent vomiting was found to have temporal lobe epilepsy (TLE). Throughout this time, during which the vomiting had become part of a vicious cycle, her epilepsy was poorly controlled by medication. Biopsychosocial approaches were employed successfully and the patient subsequently undertook training to become a home-helper, started a job, and was able to leave her parents' house and live independently. All of her symptoms resolved after she became self-sufficient. DISCUSSION: Vomiting without impaired consciousness is seldom considered to be a manifestation of epilepsy. Difficulty in recording an electroencephalogram (EEG) because of the presence of persistent vomiting delayed the diagnosis. The improvement of symptoms was thought to have been due to the patient's emotional stabilization and physical improvement, which may have stabilized the limbic system. CONCLUSION: When an illness persists for many years and conditioning and a vicious cycle occur secondarily, systematic biopsychosocial approaches are needed in addition to general treatment. Also, secondary symptoms make the diagnosis more difficult when efforts at treatment are ineffective.
