Review
Subungual lesions present a serious challenge for clinicians. The following factors can cause certain problems in interpreting the data: 1) Changes in lesion morphology over time: It may indicate the presence of a malignant lesion (increased pigmentation over time and lack of distal growth) but may actually be a benign lesion (chronic persistent subungual hematoma). 2) Patient's medical history can be misleading or difficult to verify, especially in problematic patients, or those with mental health problems or communication disorders (e.g., Asperger's syndrome, autism, schizoid psychosis, etc.). 3) The morphology of the lesion itself can be difficult to determine in the presence of simultaneously overlapping lesions. These patient dilemmas primarily concern the differentiation between subungual hematomas from subungual melanomas. The clinicians's concerns are based on the potential for metastasis and the risk of significantly worse prognosis for patients affected by nail biopsy. We present a 19-year-old patient with a subungual pigmented lesion with a clinical/dermatoscopic suspicion for subungual melanoma. Primary complaints for about 3-4 months. Intensified pigmentation and increase in size within two months led to a partial surgical resection of the nail plate and nail bed, followed by adaptation of the wound edges with single interrupted sutures. The histopathological finding was indicative of a subungual hematoma located above a focal melanocytic hyperplasia of the nail bed, clear resection lines. After a literature review, we believe that this is the first case of a patient with simultaneously present subungual benign focal melanocytic hyperplasia overlapping with a chronic persistent subungual hematoma.

INTRODUCTION
Autism is a heterogeneous neurodevelopmental disorder associated with social, cognitive and behavioral impairments. These impairments are often reported along with alteration of the brain structure such as abnormal changes in the grey matter (GM) density. However, it is not yet clear whether these changes could be used to differentiate various subtypes of autism spectrum disorder (ASD).
METHOD
We compared the regional changes of GM density in ASD, Asperger's Syndrome (AS) individuals and a group of healthy controls (HC). In addition to regional changes itself, the amount of GM density changes in one region as compared to other brain regions was also calculated. We hypothesized that this structural covariance network could differentiate the AS individuals from the ASD and HC groups. Therefore, statistical analysis was performed on the MRI data of 70 male subjects including 26 ASD (age=14-50, IQ=92-132), 16 AS (age=7-58, IQ=93-133) and 28 HC (age=9-39, IQ=95-144).
RESULT
The one-way ANOVA on the GM density of 116 anatomically separated regions showed significant differences among the groups. The pattern of structural covariance network indicated that covariation of GM density between the brain regions is altered in ASD.
CONCLUSION
This changed structural covariance could be considered as a reason for less efficient segregation and integration of information in the brain that could lead to cognitive dysfunctions in autism. We hope these findings could improve our understanding about the pathobiology of autism and may pave the way towards a more effective intervention paradigm.

Meta-Analysis
PURPOSE
This study was conducted to investigate the relationship between cesarean section (CS) offspring and autism spectrum disorders (ASD)/attention deficit hyperactivity disorder (ADHD).
METHODS
Searching of the databases (PubMed, Web of Science, Embase, and Cochrane Library) for studies on the relationship between mode of delivery and ASD/ADHD until August 2022. The primary outcome was the incidence of ASD/ADHD in the offspring.
RESULTS
This meta-analysis included 35 studies (12 cohort studies and 23 case-control studies). Statistical results showed a higher risk of ASD (odds ratio (OR) = 1.25, P < 0.001) and ADHD (OR = 1.11, P < 0.001) in CS offspring compared to the VD group. Partial subgroup analysis showed no difference in ASD risk between CS and VD offspring in sibling-matched groups (OR = 0.98, P = 0.625). The risk of ASD was higher in females (OR = 1.66, P = 0.003) than in males (OR = 1.17, P = 0.004) in the CS offspring compared with the VD group. There was no difference in the risk of ASD between CS under regional anesthesia group and VD group (OR = 1.07, P = 0.173). However, the risk of ASD was higher in the CS offspring under general anesthesia than in the VD offspring (OR = 1.62, P < 0.001). CS offspring developed autism (OR = 1.38, P = 0.011) and pervasive developmental disorder-not otherwise specified (OR = 1.46, P = 0.004) had a higher risk than VD offspring, but there was no difference in Asperger syndrome (OR = 1.19, P = 0.115). Offspring born via CS had a higher incidence of ADHD in different subgroup analyses (sibling-matched, type of CS, and study design).
CONCLUSIONS
In this meta-analysis, CS was a risk factor for ASD/ADHD in offspring compared with VD.

Review
There are many special sites at the end of a synapse called active zones (AZs). Synaptic vesicles (SVs) fuse with presynaptic membranes at these sites, and this fusion is an important step in neurotransmitter release. The cytomatrix in the active zone (CAZ) is made up of proteins such as the regulating synaptic membrane exocytosis protein (RIM), RIM-binding proteins (RIM-BPs), ELKS/CAST, Bassoon/Piccolo, Liprin-α, and Munc13-1. RIM is a scaffold protein that interacts with CAZ proteins and presynaptic functional components to affect the docking, priming, and fusion of SVs. RIM is believed to play an important role in regulating the release of neurotransmitters (NTs). In addition, abnormal expression of RIM has been detected in many diseases, such as retinal diseases, Asperger's syndrome (AS), and degenerative scoliosis. Therefore, we believe that studying the molecular structure of RIM and its role in neurotransmitter release will help to clarify the molecular mechanism of neurotransmitter release and identify targets for the diagnosis and treatment of the aforementioned diseases.

AIMS
The purpose of the study was to increase the body of knowledge related to sleep in children with autism. The specific aims were to (i) identify the subgroup of children with autism, ages 3-17 years, referred for polysomnography and (ii) describe types and frequency of clinical encounters for sleep problems in a sample of children ages 3-17 with and without the diagnosis of autism.
METHODS
The authors performed a secondary data analysis of the de-identified Nationwide Children's Hospital Sleep DataBank, a collection of encounters with children referred for polysomnography. The data were filtered for ages 3-17 years at the time of the participant's first sleep study, and further filtered for the presence of an autism diagnosis.
RESULTS
In the sample, there were 2838 unique participants (M = 10.5 years) with a total of 172 167 encounters between 2017 and 2019. Of these, 198 (7%) were diagnosed with Autism Spectrum Disorder, Asperger's Syndrome, or Pervasive Developmental Disorder. Among all participants, the most common sleep problems were apnea, snoring, non-specified sleep disorders (including restless sleeper), circadian rhythm disorder (CRD), and insomnia. The subgroup of patients diagnosed with autism was noted to have higher frequency of several types of sleep problems, especially restless sleep, CRD and insomnia, compared to those without an autism diagnosis.
CONCLUSIONS
Findings elucidate the increased presence of sleep problems in paediatric patients with autism, and the need for purposeful sleep evaluation and research given the potential impact on daytime function for these individuals and their families.

Psychiatria Polska Oct 2022Goal: to assess fMRI activation during semantic tasks in adolescents with ASD.
OBJECTIVES
Goal: to assess fMRI activation during semantic tasks in adolescents with ASD.
METHODS
Material: 44 right-handed male adolescents aged 12-19 (mean 14.3 ± 2.0) - 31 with autism spectrum disorders who met DSM-IV-TR criteria for Asperger's syndrome and 13 neurotypical adolescents matched according to age and handiness. Method: Functional testing (fMRI) was performed during semantic decisions tasks and phonological decisions in three categories of tasks: concrete nouns, verbs with plural meanings, words describing states of mind, as a control condition. Statistical analyzes were performed at the level of p <0.05 with FWE (family-wise error) correction and p <0.001.
RESULTS
Results: lower BOLD signal was demonstrated in many brain areas including precuneus, posterior cingulate gyrus, angular gyrus, parahippocampal gyrus, regardless of task category and processing method in the ASD group. The smallest differences in semantic processing were found for concrete nouns and the greatest ones for words describing states of mind.
CONCLUSIONS
Conclusions: the presence of different activation patterns in the ASD group suggests that far more than just the areas traditionally attributed to language processing, are involved in semantic deficits in ASD.

Psychiatria Polska Oct 2022Goal: to evaluate changes in the grey matter volume using the VBM method in a group of adolescents with ASD, who met the criteria for Asperger's Syndrome.
OBJECTIVES
Goal: to evaluate changes in the grey matter volume using the VBM method in a group of adolescents with ASD, who met the criteria for Asperger's Syndrome.
METHODS
Material and methods: Morphometric evaluations based on Voxel Based Morphometry (VBM) were performed on 37 male adolescents aged 12 to 19 (M = 14.3 ± 2.0), with autism spectrum disorders, who met the DSM-IV-TR criteria for Asperger's Syndrome and 15 neurotypical adolescents matched by age. Significance was set at p<0.007 without FWE correction and p<0.05 with FWE correction.
RESULTS
Results: the decrease in the volume of the grey matter was observed in ASD group including the pre- and postcentral gyrus, the superior and middle frontal gyrus, the inferior and superior parietal lobule, the praecuneus, the anterior and posterior cingulate cortex, the fusiform gyrus, the parahippocampal gyrus, the lingual gyrus, the middle occipital region, the cuneus and the angular gyrus, the regions of calcarine sulcus and the cerebellum. The majority of changes was localized bilaterally.
CONCLUSIONS
Conclusions: the decrease in the volume of grey matter observed in ASD group can be related functionally with the characteristics of deficits observed in autism spectrum disorders which highlights the role of abnormal organization of numerous CNS structures in the genesis of symptoms observed in cognitive and behavioural domains.

Deficits in socio-emotional reciprocity, in prosocial behavior and in developing social relationships are diagnostic criteria of autism spectrum disorder (ASD), usually assessed by self-report or observation. Simple social experiments developed by behavioral economists allow for quantification of ASD-related social behavior. In this study, we used such experiments to compare social-economic decision-making between ASD adolescents and neurotypical controls. Precisely, we analyzed social orienting and prosocial behavior in 17 adolescents with ASD (Asperger syndrome) and 24 matched neurotypical adolescents. We used a two-condition distribution game (possibility of punishment by fellow player versus no such possibility) and an impunity game to examine social orienting (distribution game) and prosocial behavior (both games). Participants with ASD exhibited less social orienting in the distribution game (p = 0.03, d = -0.61). In addition, there was a trend for ASD participants to behave in a more prosocial way than neurotypical participants in the impunity game (p = 0.08, d = 0.60), which was not the case in the no-punishment condition of the distribution game (p = 0.35, r = 0.17). These results demonstrate the potential of simple economic games to capture reduced social orienting in ASD. The unexpected finding of more prosocial behavior in adolescents with autism spectrum disorder than in neurotypical controls adds to the complexity of previously published results. We recommend meta-analytic efforts to determine average effect sizes across studies and elucidate the conditions for prosocial behavior in ASD to occur.

The efficacy of mindfulness-based therapy for anxiety, social skills, and aggressive behaviors in children and young people with Autism Spectrum Disorder: A systematic review.
INTRODUCTION
The purpose of this systematic review was to examine the efficacy of mindfulness-based interventions for improving anxiety, social skills, and aggressive behaviors in children and young people (CYP) with Autism Spectrum Disorder (ASD); summarize the results across clinic, home, and school contexts; and evaluate the quality of these interventions for clinical practice.
METHODS
A search of the PsycINFO, Medline (Ovid), Web of Science, and Scopus databases was conducted in June 2021, and no date restrictions were applied. Inclusion criteria were quantitative or qualitative research implementing a mindfulness-based intervention for CYP aged 6-25 years with a diagnosis of ASD, Pervasive Development Disorder, or Asperger's Syndrome.
RESULTS
We identified 23 articles for inclusion including within subject pre- and post-testing, multiple baselines, and randomized control trials, among other research designs. Of these, a quality analysis conducted using an ASD research-specific risk of bias tool found over half (14) were of weak methodological quality, whereas only four and five were found to be of strong and adequate quality, respectively.
DISCUSSION
While the results of this systematic review suggest promising evidence for the use of mindfulness-based interventions to improve anxiety, social skills, and aggressive behaviors in CYP with ASD, results should be interpreted with caution due to the limitations resulting from the overall weak quality of the studies.The review protocol was pre-registered on PROSPERO (CRD42021259125) and can be viewed at https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=259125.
