RESUMEN
Megalencephaly-polymicrogyria-polydactyly-hydrocephalus (MPPH) syndrome is a developmental brain disorder characterized by an enlarged brain size with bilateral perisylvian polymicrogyria and a variable degree of ventriculomegaly. MPPH syndrome is associated with oromotor dysfunction, epilepsy, intellectual disability and postaxial hexadactyly. The molecular diagnosis of this disorder is established by the identification of a pathogenic variant in either AKT3, CCND2 or PIK3R2. Previously reported AKT3 variants are associated with various brain abnormalities and may lead to megalencephaly. MPPH syndrome is usually due to germline pathogenic AKT3 variants. Somatic mosaic pathogenic variants associated with hemimegalencephaly, which is similar to MPPH, have also been observed. A Hungarian Roma family with two half-siblings, which present with intellectual disability, dysmorphic features, epilepsy, brain malformations, and megalencephaly was studied. Whole exome sequencing (WES) analysis was performed. WES analysis revealed a heterozygous c.1393C > T p.(Arg465Trp) pathogenic missense AKT3 variant in both affected half-siblings. The variant was verified via Sanger sequencing and was not present in the DNA sample from the healthy mother, which was derived from peripheral blood, suggesting maternal germline mosaicism. In conclusion, this is the first report in which maternal germline mosaicism of a rare pathogenic AKT3 variant leads to autosomal dominantly inherited MPPH syndrome.

The increased prevalence of minor physical anomalies (MPAs) and the abnormalities of dermatoglyphic patterns may be physical manifestations of neurodevelopmental disruption in affective disorders. This paper aims to review the current state of knowledge on the frequency of MPAs and dermatoglyphic abnormalities in mood disorders. A MEDLINE, PsychInfo and Web of Science search was carried out to collect all publications on the frequency of MPAs and on dermatoglyphic traits in bipolar disorder and unipolar depression. 24 studies on MPAs, 19 on dermatoglyphics, and 5 dealing with both were found with discrepant findings. The relative contribution of neurodevelopmental retardation to the aetiology of affective disorders remains undetermined, the field is open for further research. Increased recognition of neurodevelopmental processes in the origin of affective disorders may allow for earlier and more effective intervention and prevention.

Anti-N-methyl-D-aspartate encephalitis is an autoimmune disorder characterized by autoantibodies produced against NMDA receptors. We report the case of a 17-year-old drug user teenager who presented with altered mental scale, psychiatric symptoms and autonomic dysfunction. In the background we diagnosed NMDA encephalitis. We supposed that synthetic cannabinoids/drugs may have lead to the of trigger NMDA encephalitis via the altered activation of the immune system and molecular mimicry mechanism.

INTRODUCTION: Food addiction is a condition presenting with a similar symptomatology to that of drug addiction, with an underlying individual sensitivity and special adaptation to certain foods, being consumed regularly. The concept of food addiction created one of the central issues in addiction research, owing to the pandemic spreading of obesity causing serious public health concerns. Development of an objective, standardized measuring tool of food addiction has become markedly necessary for both research and public health purposes. METHODS: Literature overview in the fields of food addiction and Yale Food Addiction Scale (1956-2016). RESULTS: For the establishment of food addiction diagnosis, the Yale Food Addiction Scale has become the most widely used method. It is an English questionnaire consisting of 25 questions, having been developed according to the 7 substance use disorder criteria in DSM-IV. The scale provides the possibility of diagnosis establishment, as well as measurement of food addiction severity. Development of the scale has given way to a number of new scientific results. The mean prevalence of food addiction is 19.7%, being more common in women, obese individuals, people >35 years and patients with already established eating disorders (binge eating disorder, bulimia). The most common symptom is the 'persistent desire or repeated unsuccessful attempts to quit'. A positive association has been recognized between food addiction symptomcount and the reward system dysfunction. CONCLUSION: The Yale Food Addiction Scale is a psychometrically valid, objective and standardized tool, being not only useful in addiction research but also helping in diagnosis establishment in clinical practice.

INTRODUCTION: Hereditary spastic paraplegia is the overall term for clinically and genetically diverse disorders characterized with progressive and variable severe lower extremity spasticity. The most common causes of autosomal dominantly inherited hereditary spastic paraplegias are different mutations of the spastin gene with variable incidence in different ethnic groups, ranging between 15-40%. Mutations in the spastin gene lead to loss of spastins function, causing progressive neuronal failure, which results in axon degeneration finally. AIM: The molecular testing of spastin gene is available in the institution of the authors since January, 2014. The experience gained with the examination of the first eleven patients is described in this article. METHOD: After polymerase chain reaction, Sanger sequencing was performed to examine the 17 exons of the spastin gene. Multiplex ligation-dependent probe amplification was performed to detect greater rearrangements in the spastin gene. Eight of the patients were examined in the genetic counseling clinic of the authors and after detailed phenotype assessment spastin gene testing was obtained. The other three patients were referred to the laboratory from different outpatient clinics. RESULTS: Out of the 11 examined patients, four different pathogenic mutations were found in 5 patients. CONCLUSIONS: The first Hungarian data, gained with the examination of spastin gene are presented in this article. The five patients, in whom mutations were detected, represent 45.5% of all tested patients with hereditary spastic paraplegia, which is similar to those published in the international literature. Molecular testing and subsequent detailed genotype-phenotype correlations of the Hungarian patients may serve valuable new information about the disease, which later on may influence our therapeutic possibilities and decisions.

OBJECTIVE: Anti-N-methyl-D-Aspartate encephalitis is a recently diagnosed autoimmune disorder with increasing significance. During this disease antibodies are produced against the subunit of the NMDA receptor, which cause different symptoms, both psychiatric and neurological. The aim of this publication is to introduce this disease, to facilitate the diagnosis and to recommend therapeutical guideline. MATERIALS AND METHODS: In this review we summarized the relevant literature published between 2007 and 2015 giving emphasis on etiopathogenesis, diagnosis, differential diagnosis, treatment and prognosis. RESULTS: In the etiology an underlying tumor or a viral agent should be considered. During the disease we can discern 3 periods: first prodromal viral infections-like symptoms can be seen, 1-2 weeks later psychiatric symptoms, such as aggression, sleep and behavior disturbances appear. After that neurological symptoms (tonic-clonic convulsions, aphasia, catatonia, orofacial dyskinesia, autonom lability, altered mental state) are typical, and the patient's condition deteriorates. For the correct diagnosis it is necessary to detect antibodies against the NMDA receptor from the serum and the liquor. Steroids, immunoglobulins and plasmaheresis are the first-line therapies. If the disease is unresponsive, then as a second-line therapy anti-CD 20 (Rituximab) and cyclophosphamid can be useful. Most of the patients are improving without any neurological sequale with prompt detection and appropriate therapy. CONCLUSION: It is important to be familiar with the symptoms, diagnosis and therapy of this disease as a practicing clinician, especially as a psychiatrist or neurologist. 75 percentage of the patients are admitted to psychiatric departments first because of the leading symptoms. Autoimmune NMDA encephalitis is a reversible disease after early diagnosis and treatment.

BACKGROUND: The prevalence of minor physical anomalies (prenatal errors of morphogenesis) was evaluated in patients with idiopathic epilepsy to get indirect data on the possible role of aberrant neurodevelopment in the etiology of the disease. AIM: Connecting to current opinions on a possible role of aberrant neurodevelopment in idiopathic epilepsy it seems important to introduce somatic trait marker research focusing on brain maldevelopment. METHODS: A scale developed by Méhes (1985) was used to detect the presence or absence of 57 minor physical anomalies in 24 patients with idiopathic epilepsy and in 24 matched controls. RESULTS: The mean value of all minor physical anomalies was significantly higher in the group of patients compared to controls. In case of 3 minor physical anomalies we could demonstrate statistically significant differences between children with epilepsy and the control sample. Two minor malformations (primitive shape of ears, double posterior hair whorl) and one phenogenetic variant (inner epicanthic folds) had a significantly higher frequency in patients compared to control individuals. CONCLUSION: The overrepresentation of minor physical anomalies in idiopathic epilepsy can strongly support the view that this disorder is related to pathological factors operating early in development.

Minor physical anomalies are mild, clinically and cosmetically insignificant errors of morphogenesis which have a prenatal origin and may bear major informational value for diagnostic, prognostic and epidemiological purposes. Since both the central nervous system and the skin are derived from the same ectodermal tissue in utero, minor physical anomalies can be external markers of abnormal brain development and they appear more commonly in neurodevelopmental disorders. Recently studies were published on the prevalence of minor physical anomalies in the relatives of patients with schizophrenia. In a systematic review of literature 11 studies were identified with mixed results. We suppose that the differentiation of minor malformations and phenogenetic variants can help to clarify the minor anomaly profile as a potential endophenotype in schizophrenia.

UNLABELLED: Smith-Lemli-Opitz syndrome (SLOS), a multiple congenital anomaly with severe mental retardation, is caused by decreased activity of 7-dehydrocholesterol reductase. Fifteen Hungarian patients were diagnosed with SLOS on the basis of clinical symptoms, serum cholesterol, 7-dehydrocholesterol, and molecular genetic testing. Their age at the time of diagnosis in mild SLOS (n = 4, clinical score <20) was 0.5-18 years, cholesterol was 2.37 ± 0.8 mmol/L, and 7DHC was 0.38 ± 0.14 mmol/L. In the group of typical SLOS (n = 7, score 20-50), the diagnosis was set up earlier (age of 0.1-7 years); t-cholesterol was 1.47 ± 0.7 mmol/L, and 7DHC was 0.53 ± 0.20 mmol/L. Patients with severe SLOS (n = 4, clinical score > 50) died as newborns and had the lowest t-cholesterol (0.66 ± 0.27 mmol/L), and 7DHC was 0.47 ± 0.14 mmol/L. Correlation coefficient with clinical severity was 0.74 for initial t-cholesterol and 0.669 for Cho/7DHC. Statistically significant difference was between the initial t-cholesterol of mild and severe SLOS (p = 0.01), and between the Cho/7DHC ratios of groups (p = 0.004). In severe SLOS, the percentage of α-lipoprotein was significantly lower than in typical (p = 0.003) and mild SLOS (p = 0.004). Although serum albumin, total bilirubin, and hemostasis parameters remained in the reference range during cholesterol supplementation (n = 10) combined with statin therapy (n = 9), increase of aspartate aminotransferase and alanine aminotransferase in 50 % of the patients probably refers to a reversible alteration of liver function; therefore, statin therapy was suspended. CONCLUSION: life expectancy is fundamentally determined by the initial t-cholesterol, but dehydrocholesterol and α-lipoprotein have prognostic value. Accumulation of hepatotoxic DHC may inhibit the synthesis of α-lipoproteins, decreasing the reverse cholesterol transport. During statin therapy, we suggest monitoring of lipid parameters and liver function.

BACKGROUND AND PURPOSE: Minor physical anomalies are mild, clinically and cosmetically insignificant errors of morphogenesis which have a prenatal origin and may bear major informational value for diagnostic, prognostic and epidemiological purposes. Since both the central nervous system and the skin are derived from the same ectodermal tissue in utero, minor physical anomalies can be external markers of abnormal brain development and they appear more commonly in neurodevelopmental disorders. In a recently published meta-analysis Ozgen et al. have published the results of seven studies--all have used the Waldrop Scale which contains 18 minor physical anomalies--and reported on the higher prevalence of minor physical anomalies among patients with autism. There are only a very few data on the individual analysis of the prevalence of minor physical anomalies in autism. METHODS: In our study we have studied the prevalence of 57 minor physical anomalies in 20 patients with autism and in 20 matched control subjects by the use of the Méhes Scale. RESULTS: The prevalence of minor physical anomalies was significantly higher in the autism group (p < 0.001). The individual analysis of the 57 minor physical anomalies showed the significantly more frequent apperance of four signs (primitive shape of ear p = 0.047, abnormal philtrum p = 0.001, clinodactylia p = 0.002, wide distance between toes 1 and 2 p = 0.003). No correlation was found between the four significantly more common minor physical anomalies. CONCLUSION: The higher prevalence of minor physical anomalies in autism supports the neurodevelopmental hypothesis of the disorder and the individual analysis of minor physical anomalies can help to understand the nature of the neurodevelopmental defect.

Introduction: The higher rate of neuropsychiatric disorders in individuals with non-syndromic orofacial clefts has been well documented by previous studies. Our goal was to identify children with non-syndromic orofacial clefts that are at risk for abnormal neurodevelopment by assessing their developmental history and present cognitive functioning. Materials and methods: A single-center, case-controlled study was carried out at the Department of Pediatrics of the University of Pécs in Hungary. The study consisted of three phases including questionnaires to collect retrospective clinical data and psychometric tools to assess IQ and executive functioning. Results: Forty children with non-syndromic oral clefts and 44 age-matched controls participated in the study. Apgar score at 5 min was lower for the cleft group, in addition to delays observed for potty-training and speech development. Psychiatric disorders were more common in the cleft group (15%) than in controls (4.5%), although not statistically significant with small effect size. The cleft group scored lower on the Continuous Performance Test. Subgroup analysis revealed significant associations between higher parental socio-economic status, academic, and cognitive performance in children with non-syndromic orofacial clefts. Analyzes additionally revealed significant associations between early speech and language interventions and higher scores on the Verbal Comprehension Index of the WISC-IV in these children. Discussion: Children with non-syndromic orofacial clefts seem to be at risk for deficits involving the attention domain of the executive system. These children additionally present with difficulties that affect cognitive and speech development. Children with non-syndromic orofacial clefts show significant skill development and present with similar cognitive strengths as their peers. Longitudinal studies with larger sample sizes are needed to provide more conclusive evidence on cognitive deficits in children with non-syndromic orofacial clefts at risk for neurodevelopmental difficulties.
RESUMEN
OBJECTIVE: To compare psychiatric emergencies and self-harm at emergency departments (EDs) 1 year into the pandemic, to early pandemic and pre-pandemic, and to examine the changes in the characteristics of self-harm presentations. METHOD: This retrospective cohort study expanded on the Pandemic-Related Emergency Psychiatric Presentations (PREP-kids) study. Routine record data in March to April of 2019, 2020, and 2021 from 62 EDs in 25 countries were included. ED presentations made by children and adolescents for any mental health reasons were analyzed. RESULTS: Altogether, 8,174 psychiatric presentations were recorded (63.5% female; mean [SD] age, 14.3 [2.6] years), 3,742 of which were self-harm presentations. Rate of psychiatric ED presentations in March to April 2021 was twice as high as in March to April 2020 (incidence rate ratio [IRR], 1.93; 95% CI, 1.60-2.33), and 50% higher than in March to April 2019 (IRR, 1.51; 95% CI, 1.25-1.81). Rate of self-harm presentations doubled between March to April 2020 and March to April 2021 (IRR, 1.98; 95% CI, 1.68-2.34), and was overall 1.7 times higher than in March to April 2019 (IRR, 1.70; 95% CI, 1.44-2.00). Comparing self-harm characteristics in March to April 2021 with March to April 2019, self-harm contributed to a higher proportion of all psychiatric presentations (odds ratio [OR], 1.30; 95% CI, 1.05-1.62), whereas female representation in self-harm presentations doubled (OR, 1.98; 95% CI, 1.45-2.72) and follow-up appointments were offered 4 times as often (OR, 4.46; 95% CI, 2.32-8.58). CONCLUSION: Increased pediatric ED visits for both self-harm and psychiatric reasons were observed, suggesting potential deterioration in child mental health. Self-harm in girls possibly increased and needs to be prioritized. Clinical services should continue using follow-up appointments to support discharge from EDs.

Our aim was to investigate the rate and topological profile of minor physical anomalies (MPAs) in adult patients with epilepsy with the use of the Méhes Scale, a comprehensive modern scale of dysmorphology. Consecutive epilepsy patients admitted for outpatient evaluation were included. Patients with comorbidities of neurodevelopmental origin (such as autism, severe intellectual disability, attention deficit hyperactivity disorder, schizophrenia, tic disorder, Tourette syndrome, bipolar disorder, specific learning disorder and specific language impairment) were excluded. All participants underwent physical examination with the use of the Méhes Scale for evaluation of MPAs, including 57 minor signs. The frequency and topological profile of MPAs were correlated to clinical patient data using Kruskal-Wallis, chi2 tests and logistic regression model. 235 patients were included, according to the following subgroups: acquired epilepsy (non-genetic, non-developmental etiology) [N = 63], temporal lobe epilepsy with hippocampal sclerosis (TLE with HS) [N = 27], epilepsy with cortical dysgenesis etiology [N = 29], cryptogenic epilepsy [N = 69] and idiopathic generalized epilepsy (IGE) [N = 47]. As controls, 30 healthy adults were recruited. The frequency of MPAs were significantly affected by the type of epilepsy [H(6) = 90.17; p < 0.001]. Pairwise comparisons showed that all patient groups except for acquired epilepsy were associated with increased frequency of MPAs (p < 0.001 in all cases). Furrowed tongue and high arched palate were more common compared to controls in all epilepsy subgroup except for TLE (p < 0.001 or p = 0.001 in all cases). A positive association was detected between the occurrence of MPAs and antiepileptic drug therapy resistance [Exp(B) = 4.19; CI 95% 1.37-12.80; p = 0.012]. MPAs are more common in patients with epilepsy, which corroborates the emerging concept of epilepsy as a neurodevelopmental disorder. Assessment of these signs may contribute to the clarification of the underlying etiology. Moreover, as increased frequency of MPAs may indicate pharmacoresistance, the identification of patients with high number of MPAs could allow evaluation for non-pharmacological treatment in time.

Background: Neuroimaging of individuals with non-syndromic oral clefts have revealed subtle brain structural differences compared to matched controls. Previous studies strongly suggest a unified primary dysfunction of normal brain and face development which could explain these neuroanatomical differences and the neuropsychiatric issues frequently observed in these individuals. Currently there are no studies that have assessed the overall empirical evidence of the association between oral clefts and brain structure. Our aim was to summarize the available evidence on potential brain structural differences in individuals with non-syndromic oral clefts and their matched controls. Methods: MEDLINE, Scopus, Cochrane Central Register of Controlled Trials, Web of Science and Embase were systematically searched in September 2020 for case-control studies that reported structural brain MRI in individuals with non-syndromic oral clefts and healthy controls. Studies of syndromic oral clefts were excluded. Two review authors independently screened studies for eligibility, extracted data and assessed risk of bias with the Newcastle-Ottawa Scale. Random effects meta-analyses of mean differences (MDs) and their 95% confidence intervals (95% CI) were performed in order to compare global and regional brain MRI volumes. Results: Ten studies from 18 records were included in the review. A total of 741 participants were analyzed. A moderate to high risk of bias was determined for the included studies. The cerebellum (MD: -12.46 cm3, 95% CI: -18.26, -6.67, n = 3 studies, 354 participants), occipital lobes (MD: -7.39, 95% CI: -12.80, -1.99, n = 2 studies, 120 participants), temporal lobes (MD: -10.53 cm3, 95% CI: -18.23, -2.82, n = 2 studies, 120 participants) and total gray matter (MD: -41.14 cm3; 95% CI: -57.36 to -24.92, n = 2 studies, 172 participants) were significantly smaller in the cleft group compared to controls. Discussion: There may be structural brain differences between individuals with non-syndromic oral clefts and controls based on the available evidence. Improvement in study design, size, methodology and participant selection could allow a more thorough analysis and decrease study heterogeneity.
RESUMEN
Patients suffering from encephalitis may present psychiatric symptoms; however, the clinical relevance of anti-neuronal antibodies in patients experiencing a psychotic episode without encephalitis is still unclear. In this study, we examined the presence of anti-neuronal cell surface autoantibodies and onconeural autoantibodies in serum samples of 22 synthetic cannabinoid users presenting with psychosis. We found only two positive cases; however, seven patients had borderline results. Nonetheless, we found no significant correlation between anti-neuronal autoantibodies and the intensity of psychosis indicated by the Positive and Negative Syndrome Scale (PANSS) scores. The length of drug use and the combination of other drugs with synthetic cannabinoids have no significant effect on anti-neuronal autoantibody positivity. Nonetheless, the ratio of anti-citrate synthase (anti-CS) IgM and IgG natural autoantibodies was significantly lower (p = 0.036) in the anti-neuronal autoantibody-positive/borderline samples, than in the negative group. Interestingly, anti-CS IgM/IgG showed a significant negative correlation with PANSS-positive score (p = 0.04, r = -0.464). Our results demonstrated that anti-neuronal autoantibody positivity occurs in synthetic cannabinoid users, and the alteration of anti-CS IgM/IgG natural autoantibody levels points to immunological dysfunctions in these cases.
RESUMEN
Beneficial effects of perinatal DHA supply on later neurological development have been reported. We assessed the effects of maternal DHA supplementation on the neurological development of their children. Healthy pregnant women from Spain, Germany, and Hungary were randomly assigned to a dietary supplement consisting of either fish oil (FO) (500 mg/d DHA + 150 mg/d EPA), 400 µg/d 5-methyltetrahydrofolate, both, or placebo from wk 20 of gestation until delivery. Fatty acids in plasma and erythrocyte phospholipids (PL) were determined in maternal blood at gestational wk 20 and 30 and in cord and maternal blood at delivery. Neurological development was assessed with the Hempel examination at the age of 4 y and the Touwen examination at 5.5 y. Minor neurological dysfunction, neurological optimality score (NOS), and fluency score did not differ between groups at either age, but the odds of children with the maximal NOS score increased with every unit increment in cord blood DHA level at delivery in plasma PL (95% CI: 1.094-2.262), erythrocyte phosphatidylethanolamine (95% CI: 1.091-2.417), and erythrocyte phosphatidylcholine (95% CI: 1.003-2.643). We conclude that higher DHA levels in cord blood may be related to a better neurological outcome at 5.5 y of age.

In the majority of cases, anti-NMDA (N-methyl-D-aspartate) receptor encephalitis is a severe, but treatable disorder, therefore early diagnosis and adequate therapy are very important. It should be suspected in children and young women, who develop acute psychiatric symptoms and seizures. During the course of the disease severe encephalopathy, agitation, hallucinations, orofacial dyskinesias, prolonged cognitive disturbance, autonomic symptoms can be observed and akinetic mutism develops. EEG shows diffuse slowing. Brain MRI is normal or unspecific. Elevated protein, pleiocytosis and oligoclonal bands can be present in the CSF Detection of NMDA-receptor antibodies in sera or CSF confirms diagnosis. We present the case of a 15-year-old girl, who fully recovered within two months after steroid treatment and repeated plasma exchange. Ovarian teratoma has not been detected.

Minor physical anomalies are somatic markers of aberrant neurodevelopment, so the higher prevalence of these signs among the relatives of bipolar I patients can confirm minor physical anomalies as endophenotypes. The aim of the study was to evaluate the prevalence of minor physical anomalies in first-degree healthy relatives of patients with bipolar I disorder compared to normal control subjects. Using a list of 57 minor physical anomalies (the Méhes Scale), 20 first-degree unaffected relatives of patients with the diagnosis of bipolar I disorder and as a comparison 20 matched normal control subjects were examined. Minor physical anomalies were more common in the ear, head, mouth and trunk regions among the relatives of bipolar I patients compared to normal controls. By the differentiation of minor malformations and phenogenetic variants, we have found that both minor malformations and phenogenetic variants were more common among the relatives of bipolar I patients compared to the control group, while individual analyses showed, that one minor malformation (sole crease) and one phenogenetic variant (high arched palate) were more prevalent in the relative group. This is the first report in literature on the increased prevalence of minor physical anomalies among the first-degree unaffected relatives of bipolar I patients. The study support the concept, that minor physical anomalies can be endophenotypic markers of bipolar I affective disorder.
