Introduction: To investigate the hypothesis that the presence of prenatal maternal stress, increased level of prenatal testosterone, and low level of vitamin D3 in pregnancy is associated with the development of ADHD-like symptoms in toddlers (< 2 years old).

Material and methods: The study group comprised 53 pregnant women and 53 infants of these pregnancies. The population cohort of 53 pregnant women were recruited at their 35th to 37th week of pregnancy and investigated prospectively. The participants were selected through targeted selection. Maternal experience of stressful life events was assessed by stress standardised questionnaires, prenatal testosterone was determined in the mothers' saliva by using the immune enzymatic (ELISA) method, and maternal plasma D vitamin was measured using the ECLIA method, during pregnancy. When the age of the offspring was 6 months and then less than 2 years, the mothers completed the child behaviour and temperament checklist.

Results: A small but statistically significant association was found between the common symptom complex of ADHD and the level of testosterone and vitamin D3, in the presence of prenatal maternal stress. Multiple regression analysis showed that maternal stressful events during pregnancy significantly predicted ADHD behaviours in offspring.

Conclusions: The study supported the hypothesis that prenatal maternal stress, increased level of prenatal testosterone, and low level of vitamin D3 during pregnancy increases the risk of development of ADHD-like symptoms in toddlers (< 2 years old). Also, the obtained results support the hypothesis that the influence of prenatal factors causes ADHD-like symptoms in offspring through a programming effect.

Hypoglycemic encephalopathy (HE) is a type of encephalopathy resulting from extremely low blood glucose level. Symptoms are not specific and can be misdiagnosed very often. It can occur during deep and/or prolonged hypoglycemia, which may be a result of inadequately controlled diabetes. Here, we report a case of an 11-year old male patient diagnosed with type 1 diabetes mellitus treated with the use of insulin pump who was admitted to the Pediatric Neurology Department because of multiple incidents of seizures. Boy was found unconscious by his mother. The blood glucose level on the glucometer was 35 mg/dl. It turned out that the reason of hypoglycemia was inadequate insulin dosing. He was given intravenous glucose by the ambulance service without improvement in the state of consciousness. Brain MRI revealed in both cerebral hemispheres, symmetrically, elevated white matter signal, mainly in the subcortex and cortex of the frontal and occipital and parietal lobes with features of diffusion restriction. EEG revealed generalized slow brain activity, without obvious epileptiform. Boy was provided with a variety of antiepileptic drugs. Unfortunately, none of them yielded with satisfactory results so far and the patient is still suffering from drug-resistant epilepsy. In conclusion, glucose is one of the key metabolic agents for the proper brain function and any imbalances in its blood level may impair the neuronal computation. Thus, it is extremely important, especially among diabetic patients, to control glucose blood level and avoid any disturbances, as they may lead to severe consequences, such as HE and drug-resistant epilepsy.

Introduction: Precocious puberty is a pathology whose primary aetiology is still unknown; research and approach topics could guide physicians and academics to develop investigations towards knowledge trends.

Aim of the study: The objective of this study was to perform a cienciometric analysis using the Web of Science platform during the period 2000-2023 regarding precocious puberty worldwide.

Material and methods: A search formula was devised to capture documents on the Web of Science platform, including original studies, consensus, and reviews for analysis. Information on journals and documents was also manually collected by extracting data on the journal quartile or open access to the document.

Results: A total of 3,556 documents were analysed; the research trend during the study period showed steady growth, with the United States being the most prolific country. The People's Republic of China had significant growth, particularly in the last 10 years of analysis. Emerging topics since 2020 were "COVID-19", "dlk1", and "mkrn3". The most cited article is a narrative review with 1,038 citations at the time of the search and is open access article.

Conclusions: Research on precocious puberty shows growth during the study period, with new research topics that can guide physicians and researchers in the direction of their future studies. A bibliometric analysis on more specific aspects of precocious puberty could provide better guidance to researchers.

The clinical onset of type 1 diabetes (namely stage 3 type 1 diabetes [T1D]) is preceded by a relatively prolonged pre-symptomatic phase featured by islet autoimmunity [1] with (Stage 2 T1D) or without (Stage 1 T1D) dysglycaemia. While islet autoimmunity is the hallmark of the underlying autoimmune process, very little evidence is available for the metabolic changes that accompany the loss of functional beta cell mass. Indeed, a steep decline of C-peptide - a surrogate marker of beta cell function - is measurable only ~6 months before the onset of Stage 3 T1D [2]. Disease modifier drugs have, there-fore, a very limited window of intervention because we lack of effective methods to track beta cell function over time and to identify early changes of insulin secretion that precedes dysglycaemia [3, 4] and clinically symptomatic diabetes. Herein, we will revise current approaches to longitudinally track beta cell function over time before the onset of Stage 3 T1D, which might be suitable for monitoring the risk for diabetes progression as well as the effectiveness of disease modifier treatments.

Introduction: In view of the modifications in the endocrine society guidelines on evaluation and management of children with congenital adrenal hyperplasia (CAH), we performed a review of children and adolescents with CAH.

Material and methods: An audit of 35 children with CAH presenting to the pediatric endocrinology clinic between January 2014 to November 2021 was conducted by formulating ten audit questions. The areas of focus included: genital reconstructive surgery, neonatal screening for CAH, stress dosing, need for adrenocorticotrophic hormone (ACTH) stimulation test, growth promoting therapy, bone age assessment, adrenal imaging, bone mineral density assessment, adequacy of hormone replacement and appropriate management of non-classical CAH.

Results: Conservative approach to genitoplasty in female children increased from 42.9% to 88.9%. Newborn screening identified 4 babies including two asymptomatic males averting saltwasting crisis. Stress dosing of steroids were advised in all and emergency usage of injectable glucocorticoids was warranted in two children. Gonadotropin-releasing hormone (GnRH) analogue therapy improved the final median predicted height by 7 cm in 5 children. Twenty-three (65.7%) had bone age assessment with 14 (40%) having advanced bone age. ACTH stimulation test, Adrenal imaging, dual energy X-ray absorptiometry (DEXA) scan were done in accordance with the guideline. One child with nonclassical CAH was initiated on hydrocortisone replacement for advanced bone age.

Conclusions: A shift to conservative surgical management of females, utility of neonatal screening for CAH, judicious use of growth promoting therapy is highlighted. Need for bone age testing, emergency hydrocortisone provision is warranted in our series.

Compared with healthy children, peers with type 1 diabetes mellitus (DM1) have an increased risk of developing advanced atherosclerosis and cardiovascular disease (CVD). Glycaemic control is the most important modifiable risk factor for CVD in DM1. Currently, monitoring of glycaemic control relies on glycosylated haemoglobin levels (HbA1c), self-monitoring of blood glucose (SMBG), and the use of continuous glucose monitoring (CGM) systems. The flow-mediated dilatation (FMD), pulse wave velocity (PWV), ankle-brachial index (ABI), and carotid intima-media thickness (cIMT) may be used to assess the risk of CVD, by estimating the process of atherosclerosis in peripheral vessels. Aim of the study: To summarize the current literature on the correlation of metabolic control in young people with DM1, assessed by key metrics from CGM reports, and the development of atherosclerosis and the incidence of CVD. Conclusions: Chronic hyperglycaemia is an independent risk factor for vascular changes. The effect of glycaemic control - assessed on the basis of parameters obtained from CGM reports - on the risk of CVD in DM1 has been analysed in few studies, especially in the paediatric population.

Introduction: Type 1 diabetes mellitus (T1DM) is one of the most common chronic diseases in childhood. Because acute glycaemic com-plications account for most concerns in the management of T1DM in children, special attention during the challenging time of the global COVID-19 pandemic is required to prevent deteriorations resulting in acute hospitalization.

Aim of the study: is to assess how the COVID-19 pandemic influenced the incidence and causes of acute hospitalizations and emergency room visits in adolescents with established type 1 diabetes mellitus, and to characterize the admitted population.

Material and methods: The study was conducted as a retrospective evaluation of acute hospitalizations of 39 T1DM patients between 15 and 17 years of age in the period 2018-2021.

Results: No difference was noted in the incidence of acute hospitalizations and DKA or the biochemical parameters of adolescents with T1DM between the pre-COVID (23 patients in 2018-2019) and COVID period (16 patients in 2020-2021). It is, howev-er, worth underlying that 6/11 (55%) patients hospitalised in 2021 experienced diabetes deterioration as a result of emo-tional distress - a phenomenon that was not present in the pre-COVID era. After excluding of the hospitalizations due to psy-chosocial causes, a significant decrease in the number of acute hospitalizations in the COVID period was observed.

Conclusions: We suppose that increased parental supervision during the pandemic might have prevented some of the episodes of severe disease decompensation, but this was masked by the sharp increase in hospitalizations due to emotional distress. Our data confirmed that psycho-emotional status is an important factor in the treatment of T1DM.
