Ciele: Predkladaný výskum sa zaoberá identifikáciou prenatálnych faktorov vplývajúcich na abnormálny neurovývin a postnatálnu manifestáciu autistického fenotypu v súbore 107 chlapcov (priemerný vek 4,31 ± 2,24). Súbor a metódy: Biologické matky autistických chlapcov poskytli údaje týkajúce sa ich reprodukčného zdravia, infekcií počas gravidity, užívaní orálnej antikoncepcie pred počatím, prípadne užívaním návykových látok pred a počas gravidity a tiež informácie týkajúce sa novorodenca. Následne boli chlapci dia gnostikovaný na poruchy autistického spektra (PAS), pomocou dia gnostických nástrojov ADOS-2 (Autism Dia gnostic Observation Schedule) a ADI-R (Autism Dia gnostic Interview – Revised). V ADOSE-2 bol zvolený dia gnostický modul podľa rečových schopností dieťaťa, buď Modul 1 – neverbálny alebo minimálne verbálny chlapci (n = 68) a verbálni chlapci (n = 39). Výsledky: Na základe našich výsledkov, má reprodukčné zdravie matky súvisiace s dĺžkou menštruačného cyklu pred graviditou s autistickým dieťaťom, súvis s mierou rečového postihnutia (p = 0,017), taktiež počet predošlých tehotenstiev (p = 0,026). Matky neverbálnych detí uvádzali kratší cyklus (27,35 dní ± 6,60) ako matky verbálnych detí (30,14 days ± 4,44) a mali viac predošlých tehotenstiev (0,93 ± 1,07 vs. 0,51 ± 0,91). Neuviedli však počet živo narodených detí pred tehotenstvom s autistickým dieťaťom. Deti, ktoré boli neskôr dia gnostikované ako neverbálne, mali dlhší pôrod (od 2 do 48 hod; v priemere 11,13 hod, SD = 9,49), ako verbálne (od 1 do 27 hod, čo bolo v priemere 7,09 hod, SD = 8,91), p = 0,0182. Spôsob pôrodu nezohrával úlohu, ani spôsob počatia (prirodzené vs. umelé). Záver: Skúmanie prenatálnych faktorov v etiológii autizmu z hľadiska rečového vývinu sa javí ako dobrý prístup.
Objectives: The presented research aimed to identify prenatal factors involved in abnormal neurodevelopment and postnatal manifestation of an autistic phenotype in 107 boys (average age 4.31 ± 2.24 years). Materials and methods: Their biological mothers were asked to fill out a comprehensive questionnaire about their reproductive health, infections during pregnancy, oral contraceptive intake before conception, and potential substance abuse before and during pregnancy as well as delivery and newborn information. The boys were subsequently diagnosed with autism spectrum disorder (ASD) using the combination of Autism Diagnostic Observation Schedule (ADOS-2) and Autism Diagnostic Interview – Revised (ADI-R). Based on the ADOS-2 module chosen during diagnosis, boys diagnosed with Module 1 can be classified as nonverbal or minimally verbal (N = 68), while those diagnosed using Module 3 are fully verbal (N = 39). Results: According to our results, reproductive health related to the length of the menstrual cycle before pregnancy with the autistic child seems to play a role with regards to the severity of the disorder (P = 0.017) as well as the number of previous pregnancies (P = 0.026). Mothers of nonverbal children reported to have had a much shorter menstrual cycle (27.35 ± 6.60 days) than those with verbal children (30.14 ± 4.44 days) and reported more previous pregnancies (0.93 ± 1.07 vs. 0.51 ± 0.91), while not reporting the number of live births before they had the autistic child. Children who were later diagnosed as non-verbal had a longer delivery time (from 2 to 48 hours; on average 11.13 hours, SD = 9.49) than verbal ones (between 1 and 27 hours, which was on average 7.09 hours, SD = 8.91), P = 0.0182. Delivery method didn’t play a role in this context, and neither did the type of conception (natural, insemination, etc.). Conclusion: Studying the involvement of prenatal factors in the etiology of autism based on the speech of the child seems to be a promising approach.

Vitamin C deficiency resulting in scurvy, is considered to be a rare nutritional disorder in developed countries, thus leading to underdiagnosis with exposure to unnecessary investigations and delay in appropriate treatment. The wide myriad of clinical signs and symptoms with which vitamin C deficiency can present (including haematological, musculoskeletal and vague constitutional symptoms that overlap with other common medical conditions), also contributes to this diagnostic challenge. Despite scurvy being habitually thought to be present in children with neurodevelopmental conditions such as autism spectrum disorder, other important at-risk groups that frequently tend to be forgotten include children with persistent fussy eating behaviour, and children with abnormal vitamin C metabolism. We hereunder present a case of a 10-year-old boy who presented to an acute general hospital for further investigation with gait disturbance. The lack of detailed nutritional assessment on presentation in the first instance led to a missed diagnosis of vitamin C deficiency, thus exposing the child to a wide array of unnecessary investigations and treatments. The added perplexity to the case resulting from false positive results of investigations performed as part of this child's workup, is also discussed.

INTRODUCTION: Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by deficits in social communication and the presence of restricted interests and repetitive behaviors. Transient hyperphosphatasemia of infancy and early childhood (THI) is a benign laboratory disorder characterized by transiently extremely elevated activity of serum alkaline phosphatase (S-ALP). CASE REPORT: We present a 21-month-old girl with a right leg limp, most probably due to reactive arthritis after febrile viral infection, and deterioration of psychomotor development with concomitant transient elevation of S-ALP (61.74 μkat/L; normal 2.36-7.68 μkat/L). Normal values of serum creatinine, aspartate-aminotransferase, alanin-aminotransferase, calcium, phosphate, together with normal wrist X-ray ruled out rickets or other bone or hepatic cause of high S-ALP. The S-ALP gradually decreased within 3 months, thus fulfilling the THI criteria. Screening for inborn errors of metabolism was negative and meticulous neurologic, psychologic and psychiatric assessment pointed to the diagnosis of autism spectrum disorder (ASD). There was no causal relationship between THI and ASD, as high S-ALP was an accidental and transient finding within the routine laboratory assessment. However, when THI occurs in a child with an onset of a new disorder, or with a pre-existing bone or liver disease, it might seriously concern the physician. CONCLUSION: Children with THI should be spared from extensive evaluations and unnecessary blood draws.

BACKGROUND: The genetic disorder tuberous sclerosis complex (TSC) is frequently accompanied by the development of neuropsychiatric disorders, including autism spectrum disorder and intellectual disability, with varying degrees of impairment. These co-morbidities in TSC have been linked to the structural brain abnormalities, such as cortical tubers, and recurrent epileptic seizures (in 70-80% cases). Previous transcriptomic analysis of cortical tubers revealed dysregulation of genes involved in cell adhesion in the brain, which may be associated with the neurodevelopmental deficits in TSC. In this study we aimed to investigate the expression of one of these genes - cell-adhesion molecule contactin-3. METHODS: Reverse transcription quantitative polymerase chain reaction for the contactin-3 gene (CNTN3) was performed in resected cortical tubers from TSC patients with drug-resistant epilepsy (n = 35, age range: 1-48 years) and compared to autopsy-derived cortical control tissue (n = 27, age range: 0-44 years), as well as by western blot analysis of contactin-3 (n = 7 vs n = 7, age range: 0-3 years for both TSC and controls) and immunohistochemistry (n = 5 TSC vs n = 4 controls). The expression of contactin-3 was further analyzed in fetal and postnatal control tissue by western blotting and in-situ hybridization, as well as in the SH-SY5Y neuroblastoma cell line differentiation model in vitro. RESULTS: CNTN3 gene expression was lower in cortical tubers from patients across a wide range of ages (fold change = - 0.5, p < 0.001) as compared to controls. Contactin-3 protein expression was lower in the age range of 0-3 years old (fold change = - 3.8, p < 0.001) as compared to the age-matched controls. In control brain tissue, contactin-3 gene and protein expression could be detected during fetal development, peaked around birth and during infancy and declined in the adult brain. CNTN3 expression was induced in the differentiated SH-SY5Y neuroblastoma cells in vitro (fold change = 6.2, p < 0.01). CONCLUSIONS: Our data show a lower expression of contactin-3 in cortical tubers of TSC patients during early postnatal period as compared to controls, which may affect normal brain development and might contribute to neuropsychiatric co-morbidities observed in patients with TSC.
