RESUMO
OBJECTIVE@#To analyze the clinical and genetic features of a patient with mevalonate kinase deficiency (MKD).@*METHODS@#Whole exome sequencing was carried out for the proband. Candidate variant was verified by Sanger sequencing.@*RESULTS@#The proband was found to harbor compound heterozygous variants of the MVK gene, including a c.248C>T (p.Phe83Cys) variant derived from his father and a c.971C>T (p.Ala324Val) variant from his mother. Based on the guidelines of the American College of Medical Genetics and Genomics, both variations were predicted to be likely pathogenic (PM1 + PM2 + PM3 + PP3).@*CONCLUSION@#The compound heterozygous variants of the MVK gene probably underlay the MKD in the proband. Above findings have enriched the mutational spectrum of the MVK gene.

OBJECTIVE@#To explore the clinical features, prognosis and survival of patients with IgD multiple myeloma (MM).@*METHODS@#The clinical data of 20 patients with IgD MM was analyzed retrospectively. The prognostic factors and survival analysis was carried out. We summarized their clinical characteristics. The survival analysis was carried out by Kaplan-Meier method, and the prognostic factor were analyzed by using log-rank test for single factor analysis of observation index. Variables of P<0.15 in single factor analysis were enrolled in multifactor cox regression analysis.@*RESULTS@#IgD MM patients accounted for 4.3% of all MM patients in the same period, among which 80% were male, the median age of patients was 57.5(35-77) years old, 90% of the patients belongs to λ light chain type. At the time of diagnosis, 18 patients (90%) were in DS-Ⅲ stages, while 10 patients were in ISS-Ⅲ stage. The first clinical manifestations were fatigue, bone pain, kidney function impairment, anemia (Hb<100 g/L) in 14 cases (70%), 12 cases (60%) with osteolytic bone destruction≥3, combined with renal impairment in 8 cases (40%), and elevated blood calcium in 11 cases (51.4%). In only 5 patients the ratio of albumin to globntin was inverted, hypoalbuminemia accounted for 40%, and globulin increase accounted for only 15%. FISH results showed that the positive rate of 1q21 amplification (50%) was the highest, and it was easy to occur at the same time as other cytogenetic abnormalities. Extramedullary infiltration occurred in 4 cases (20%). The analysis of prognostic factors showed that only the increase of lactate dehydrogenase (LDH) level was an independent poor prognostic factor for IgD MM patients. Extramedullary infiltration and various cytogenetic abnormalities were found in 2 IgD MM patients with primary drug resistance, suggesting that extramedullary infiltration and various cytogenetic abnormalities may be prognostic factors, but the difference was not statistically significant, Which maybe related to the small sample size. All 20 patients were treated with bortezomib-containing regimen, of which 19 patients were evaluated, 17 patients (89.4%) showed effective, including CR+VGPR (52.6%), PR (31.5%), MR (5.3%), 2 patients primary drug resistance. The median PFS and OS was 9.5 and 10.5 months, respectively.@*CONCLUSION@#IgD MM is a rare and invasive disease. Increased LDH is an independent prognostic factor. Bortizomib-containing regimen can improve the prognosis of IgD MM patients.

A deficiência de mevalonato quinase (MVK; MIM #142680; ORPHA #343) é uma doença genética, espectral, rara, associadas a mutações ao longo do gene MVK causando distúrbios na síntese do colesterol, que culminam em: inflamação sistêmica com febre, adenopatia, sintomas abdominais e outros achados clínicos. Enquanto no polo leve da doença os achados mais comuns são febres recorrentes com linfadenopatia, no polo mais grave adiciona-se o acometimento do sistema nervoso central (meningites assépticas, vasculites e atraso do desenvolvimento neuropsicomotor) e do sistema hematopoiético (síndrome de ativação macrofágica). Apesar de inúmeras terapêuticas, os bloqueadores da interleucina-1 ainda são os únicos medicamentos capazes de controlar a doença e de impedir a evolução para amiloidose. Os estudos atuais visam tentar novos tratamentos, como o transplante de células-tronco hematopoiéticas, ou mesmo a terapia gênica.
Mevalonate kinase deficiency (MVK; MIM #142680; ORPHA #343) is a rare spectral genetic disorder linked to mutations along the MVK gene leading to impaired cholesterol synthesis, clinically observed as systemic inflammation with fever, adenopathy, abdominal manifestations, and other clinical findings. While on mild forms recurrent fever with lymphadenopathy is commonly observed, severe forms add to that neurological (aseptic meningitis, vasculitis, and neuropsychomotor developmental delay) and hematopoietic involvement (macrophage activation syndrome). Despite of several therapeutic approaches, blocking interleukin-1 is the only effective method to control the disease and prevent the development of systemic amyloidosis. Ongoing studies aim to test new treatments, such as hematopoietic stem cell transplantation and gene therapy.

OBJECTIVES: Internet gaming disorder (IGD) is associated with attention deficit/hyperactivity disorder (ADHD) or depression etc. We tried to examine the mediating effects of depression in the relationship between ADHD and IGD.METHODS: This study was conducted on 2000 people who participated in on-line survey among 14–39 year-old men and women in 2017. And we clarified the relationship among IGD, ADHD, and depression and tested the mediation model. The mean and standard deviation of the main variables were calculated and correlation analysis was performed to confirm the relationship among the main variables. In order to test the mediating effect of depression on the relationship between ADHD and IGD, the structural equation model was implemented using AMOS 21 (IBM).RESULTS: There were significant correlations among the variables; IGD, ADHD and depression. Depression had a mediating effect 0.23 (95% confidence interval : 0.17–0.28) in the relationship between IGD and ADHD.CONCLUSIONS: This study showed that depression can mediate ADHD and IGD. Therefore, the evaluation and management of depression and ADHD should be included in the diagnosis and treatment of IGD.

Glial cell line-derived neurotrophic factor (GDNF) has been reported to be involved in negatively regulating the effects of addictive disorders. The objective of this study was to investigate alterations in the levels of GDNF in patients with Internet gaming disorder (IGD) and to assess the relationship between GDNF levels and the severity of IGD indices. Nineteen male patients with IGD and 19 sexmatched control subjects were evaluated for alteration of plasma GDNF levels and for relationship between GDNF levels and clinical characteristics of Internet gaming, including the Young's Internet Addiction Test (Y-IAT). The GDNF levels were found to be significantly low in patients with IGD (103.2±62.0 pg/mL) compared with the levels of controls (245.2±101.6 pg/mL, p<0.001). GDNF levels were negatively correlated with Y-IAT scores (Spearman's rho=-0.645, p=<0.001) and this negative correlation remained even after controlling for multiple variables (r=-0.370, p=0.048). These findings support the assumed role of GDNF in the regulation of IGD.

BACKGROUND: Studying immigrants may have the potential to explore how cultural and environmental changes affect the internet game play patterns of individuals in the two countries. We planned to compare risk and preventive factors for Internet Gaming Disorder (IGD) between Korean adolescents in Korea and immigrant Koreans in the US. METHODS: Ninety-four Koreans and 133 immigrant Koreans were recruited. Independent factors consisted of five domains including demographic data, physical activity, academic, art, and music activities, psychological factors, and game and media play. The dependent variable in the current study was the high-risk group of IGD, which was assessed with Young’s Internet Addiction Scale scores. To determine the protective and risk factors for IGD, we performed a multiple logistic regression analysis using the high-risk group as the dependent variable. RESULTS: Five domains affected the risk for IGD in Korean and immigrant Korean groups. Vigorous physical activity was the strongest protective factor for IGD in the Korean group, while media activity was the strongest protective factor for IGD in immigrant Koreans in the US. CONCLUSION: The results indicate that internet gaming problems might be affected by environmental factors and it is recommended that gaming activity is substituted with physical activity, extracurricular classes, books, and music.

OBJECTIVES: Open and supportive communication between parents and children is known to reduce adolescents' delinquent behavior. Recently, the risk of Internet gaming disorder (IGD) has been increasing in adolescents. The purpose of this study was to investigate the mediating effects of parent-child communication styles on the relationship between adolescent aggressiveness and risk of IGD.METHODS: Participants in this study were 402 first-year students from 4 middle schools in Seoul who enrolled in the Internet user Cohort for Unbiased Recognition of gaming disorder in Early adolescence (iCURE) and completed baseline assessment in 2016. The structural equation model was constructed based on an aggression questionnaire, the Internet game use-elicited symptom screen, a mother-child communication inventory, and a father-child communication inventory.RESULTS: Adolescents' aggressiveness was found to be related to their risk of IGD. The father-child communication style mediated the relationship between aggression and risk of IGD. However, the mother-child communication style had no mediating effect.CONCLUSIONS: Our findings suggest that fathers should make an effort to improve open and positive communication skills with their children, because the father-child communication style plays an important role in the relationship between adolescent aggressiveness and risk of IGD.

OBJECTIVE: Alteration in glutamatergic neurotransmission and dopaminergic dysfunction has been implicated in both the initiation and expression of addiction related behaviors. This pilot study was aimed to investigate the serum levels of glutamate and dopamine in adults with internet gaming disorder (IGD). METHODS: We measured serum levels of glutamate and dopamine in male participants with IGD (n=26) and age-matched healthy controls (n=25). Clinical interviews were performed to identify IGD and to rule out psychiatric comorbidities. Serum levels of glutamate and dopamine were examined by enzyme immunoassays using ELISA Kits. RESULTS: Serum levels of glutamate were lower among IGD than control (IGD: 24.184±12.303 μg/ml; control: 33.676±12.413μg/ml; t=2.742, p=0.008), while levels of dopamine did not differ between. Serum glutamate and dopamine levels did not correlate with gaming hours and exposure to game in the IGD group. But serum glutamate levels were positively correlated with the dopamine levels (r=0.360, p=0.013). CONCLUSION: Our results suggest that altered glutamatergic neurotransmission may contribute to the pathophysiology of IGD.

OBJECTIVES: Internet gaming disorder (IGD) is known to be related to stress and the serotonin-transporter-linked polymorphic region (5-HTTLPR) that is known to be associated with stress and has been studied to affect various psychiatric illness outbreaks. We tried to examine the relationship between stress, 5-HTTLPR and IGD. METHODS: A total of 59 participants with IGD, diagnosed according to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria and 67 normal controls (NC) were enrolled. The IGD group and the NC were compared using chisquare test and independent sample t-test, and logistic regression analysis was used to examine the relationship between stress, the 5-HTTLPR, and IGD. RESULTS: The mean scores for anxiety, impulsivity and stress were significantly higher in the IGD group than in the NC. In addition, there was a significant association between stress and IGD [odds ratio (OR) = 1.172, 95% confidence interval (CI) = 1.008–1.362]. CONCLUSIONS: This study showed that stress would affect IGD. Therefore, the evaluation and management of stress should be included in the diagnosis and treatment of IGD.

OBJECTIVE: Several studies have suggested the efficacy of bupropion and escitalopram on reducing the excessive internet game play. We hypothesized that both bupropion and escitalopram would be effective on reducing the severity of depressive symptoms and internet gaming disorder (IGD) symptoms in patients with both major depressive disorder and IGD. However, the changes in brain connectivity between the default mode network (DMN) and the salience network were different between bupropion and escitalopram due to their different pharmacodynamics. METHODS: This study was designed as a 12-week double blind prospective trial. Thirty patients were recruited for this research (15 bupropion group+15 escitalopram group). To assess the differential functional connectivity (FC) between the hubs of the DMN and the salience network, we selected 12 regions from the automated anatomical labeling in PickAtals software. RESULTS: After drug treatment, the depressive symptoms and IGD symptoms in both groups were improved. Impulsivity and attentional symptoms in the bupropion group were significantly decreased, compared to the escitalopram group. After treatment, FC within only the DMN in escitalopram decreased while FC between DMN and salience network in bupropion group decreased. Bupropion was associated with significantly decreased FC within the salience network and between the salience network and the DMN, compared to escitalopram. CONCLUSION: Bupropion showed greater effects than escitalopram on reducing impulsivity and attentional symptoms. Decreased brain connectivity between the salience network and the DMN appears to be associated with improved excessive IGD symptoms and impulsivity in MDD patients with IGD.

Internet gaming disorder (IGD) is often comorbid with attention deficit hyperactivity disorder (ADHD). In this study, we compared the neurobiological differences between ADHD comorbid with IGD (ADHD+IGD group) and ADHD without comorbidity (ADHD-only group) by analyzing quantitative electroencephalogram (QEEG) findings. We recruited 16 male ADHD+IGD, 15 male ADHD-only adolescent patients, and 15 male healthy controls (HC group). Participants were assessed using Young's Internet Addiction Scale and ADHD Rating Scale. Relative power and inter- and intra-hemispheric coherences of brain waves were measured using a digital electroencephalography (EEG) system. Compared to the ADHD-only group, the ADHD+IGD group showed lower relative delta power and greater relative beta power in temporal regions. The relative theta power in frontal regions were higher in ADHD-only group compared to HC group. Inter-hemispheric coherence values for the theta band between F3–F4 and C3–C4 electrodes were higher in ADHD-only group compared to HC group. Intra-hemispheric coherence values for the delta, theta, alpha, and beta bands between P4–O2 electrodes and intra-hemispheric coherence values for the theta band between Fz–Cz and T4–T6 electrodes were higher in ADHD+IGD group compared to ADHD-only group. Adolescents who show greater vulnerability to ADHD seem to continuously play Internet games to unconsciously enhance attentional ability. In turn, relative beta power in attention deficit in ADHD+IGD group may become similar to that in HC group. Repetitive activation of brain reward and working memory systems during continuous gaming may result in an increase in neuronal connectivity within the parieto-occipital and temporal regions for the ADHD+IGD group.

Due to the increasing use of the internet, various social problems have been emerging, and one of them is internet gaming disorder (IGD). The purpose of this study was to investigate whether low internal motivation was present in IGD and basic psychological needs affected internal motivation. Twenty-one individuals with IGD and 21 healthy controls performed a ‘motivation task’ in which the avatar in virtual reality asked whether they would accept an activity in two conditions stimulating intrinsic or extrinsic motivation. The task performance was compared between the two groups, and was correlated with the Basic Psychological Needs Scale scores. Patients had a significantly lower acceptance rate of the proposal in the intrinsic motivation condition than controls, and this intrinsic motivated tendency was correlated with the satisfaction in their basic psychological needs. As with other substance use disorders, IGD was associated with a lower level of internal motivation, which was related to the dissatisfaction of basic psychological needs such as autonomy, competence, and relationship.

OBJECTIVE: This study aimed to develop and validate a Structured Clinical Interview for Internet Gaming Disorder (SCI-IGD) in adolescents. METHODS: First, we generated preliminary items of the SCI-IGD based on the information from the DSM-5 literature reviews and expert consultations. Next, a total of 236 adolescents, from both community and clinical settings, were recruited to evaluate the psychometric properties of the SCI-IGD. RESULTS: First, the SCI-IGD was found to be consistent over the time period of about one month. Second, diagnostic concordances between the SCI-IGD and clinician's diagnostic impression were good to excellent. The Likelihood Ratio Positive and the Likelihood Ratio Negative estimates for the diagnosis of SCI-IGD were 10.93 and 0.35, respectively, indicating that SCI-IGD was ‘very useful test’ for identifying the presence of IGD and ‘useful test’ for identifying the absence of IGD. Third, SCI-IGD could identify disordered gamers from non-disordered gamers. CONCLUSION: The implications and limitations of the study are also discussed.

OBJECTIVE: To explore the structure of Internet gaming disorder (IGD) criteria and their distribution according to the different severity level of IGD. The associations of psychiatric comorbidities to each IGD symptom and to the IGD severity were also investigated. METHODS: Consecutively recruited 330 Korean middle school students underwent face-to-face diagnostic interviews to assess their gaming problems by clinicians. The psychiatric comorbidities were also evaluated with a semi-structured instrument. The data was analyzed using principal components analysis and the distribution of criteria among different severity groups was visualized by plotting univariate curves. RESULTS: Two principal components of ‘Compulsivity’ and ‘Tolerance’ were extracted. ‘Decrease in other activities’ and ‘Jeopardizing relationship/career’ may indicate a higher severity of IGD. While ‘Craving’ deserved more recognition in clinical utility, ‘Tolerance’ did not demonstrate much difference in distribution by the IGD severity. Internalizing and externalizing psychiatric disorders differed in distribution by the IGD severity. CONCLUSION: A hierarchic presentation of IGD criteria was revealed. ‘Decrease in other activities’ and ‘Jeopardizing relationship/career’ may represent a higher severity, thus indicating more clinical attention to such symptoms. However, ‘Tolerance’ was not found to be a valid diagnostic criterion.

Internet gaming disorder (IGD) has many comorbid psychiatric problems including major depressive disorder (MDD). In the present study, we compared the neurobiological differences between MDD without comorbidity (MDD-only) and MDD comorbid with IGD (MDD+IGD) by analyzing the quantitative electroencephalogram (QEEG) findings. We recruited 14 male MDD+IGD (mean age, 20.0 ± 5.9 years) and 15 male MDD-only (mean age, 20.3 ± 5.5 years) patients. The electroencephalography (EEG) coherences were measured using a 21-channel digital EEG system and computed to assess synchrony in the frequency ranges of alpha (7.5–12.5 Hz) and beta (12.5–35.0 Hz) between the following 12 electrode site pairs: inter-hemispheric (Fp1–Fp2, F7–F8, T3–T4, and P3–P4) and intra-hemispheric (F7–T3, F8–T4, C3–P3, C4–P4, T5–O1, T6–O2, P3–O1, and P4–O2) pairs. Differences in inter- and intra-hemispheric coherence values for the frequency bands between groups were analyzed using the independent t-test. Inter-hemispheric coherence value for the alpha band between Fp1–Fp2 electrodes was significantly lower in MDD+IGD than MDD-only patients. Intra-hemispheric coherence value for the alpha band between P3–O1 electrodes was higher in MDD+IGD than MDD-only patients. Intra-hemispheric coherence values for the beta band between F8–T4, T6–O2, and P4–O2 electrodes were higher in MDD+IGD than MDD-only patients. There appears to be an association between decreased inter-hemispheric connectivity in the frontal region and vulnerability to attention problems in the MDD+IGD group. Increased intra-hemisphere connectivity in the fronto-temporo-parieto-occipital areas may result from excessive online gaming.

OBJECTIVE: The Section III of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) proposed nine diagnostic criteria and five cut-point criteria for Internet Gaming Disorder (IGD). We aimed to examine the efficacy of such criteria. METHODS: Adults (n=3041, men: 1824, women: 1217) who engaged in internet gaming within last 6 months completed a self-report online survey using the suggested wordings of the criteria in DSM-5. Major characteristics, gaming behavior, and psychiatric symptoms of IGD were analyzed using ANOVA, chi-square, and correlation analyses. RESULTS: The sociodemographic variables were not statistically significant between the healthy controls and the risk group. Among the participants, 419 (13.8%) were identified and labeled as the IGD risk group. The IGD risk group scored significantly higher on all motivation subscales (p<0.001). The IGD risk group showed significantly higher scores than healthy controls in all nine psychiatric symptom dimensions, i.e., somatization, obsession-compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism (p<0.001). CONCLUSION: The IGD risk group showed differential psychopathological manifestations according to DSM-5 IGD diagnostic criteria. Further studies are needed to evaluate the reliability and validity of the specific criteria, especially for developing screening instruments.

A growing body of evidence supports that Internet gaming disorder (IGD) is considered as ‘behavioral addiction’ with neurobiological alterations. We have reviewed previous research into the clinical and neurobiological features of IGD, and suggest a flowchart for the comprehensive evaluation of IGD. Several self-rating screening tests based on Diagnostic and Statistical Manual of Mental Disorder, 5th edition (DSM-5) IGD criteria were developed. IGD is often comorbid with depressive disorder, social anxiety disorder, attention deficit/hyperactivity disorder (ADHD), and smartphone addiction. Individuals with IGD are prone to act impulsively and make risky decisions, especially in response to game-related cues. Functional neuroimaging results have shown altered functional activities in prefrontal cortex, cingulate cortex, superior temporal gyrus and nucleus accumbens (NAc). Structural neuroimaging demonstrated gray matter volume changes in prefrontal cortex and NAc, while showing white matter integrity disruption in thalamus and posterior cingulate cortex. There are few evidences on the attribution of specific genes to IGD. To evaluate IGD comprehensively, self-rating scales based on DSM-5 are useful, but a diagnostic interview by a clinician is more helpful to assess functional impairments of IGD. Presence of psychiatric comorbidities such as depressive disorder, social anxiety disorder, ADHD, and smartphone addiction should be evaluated. Neurocognitive tests that assess impulsivity, decision-making under risk, and cue-reactivity are helpful when planning individualized IGD treatment.

Interstitial granulomatous dermatitis (IGD) is a rare disease that has been associated with multiple systemic diseases, particularly autoimmune conditions like rheumatoid arthritis and systemic lupus erythematosus. IGD has a variable clinical presentation and highly characteristic histological features of interstitial infiltrate of histiocytes between the degenerated collagen bundles. Here we report the case of a 63-year-old woman who presented with a 3-month history of multiple asymptomatic erythematous papules on the bilateral aspects of the trunk. A histopathological examination of the lesion showed an interstitial lymphohistiocytic infiltrate in the dermis. There were also foci of palisading histiocytes along with degenerating collagen bundles.
