A Systematic Review on the Adult Alpha Brainwave Activity After Essential Oil Inhalation.

Aroma extracts from plant species have been utilized since ancient times for a variety of discomforting circumstances. Aromatherapy is a recognized complementary therapeutic treatment performed in various ways such as massage or dermal application, with its main uses involving relaxation, pain relief, and stress management. Several studies have outlined that inhalation of fragrance may influence the brain function since their components can cross the blood-brain barrier and interact with central nervous system receptors. The aim of this review was to systematically present findings regarding alpha brain wave activity reported exclusively by electroencephalography. The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The PubMed and Scopus databases were screened for relevant papers, based on specific eligibility criteria. The final step of the process resulted in 13 studies published between 1998 and 2021, using different essential oils. Most of the studies revealed the increase of alpha brainwave activity post-essential oil inhalation. Given the proven positive outcomes of increased alpha wave activity on several domains such as cognitive performance and better mental state, further research on the impact of essential oil inhalation is warranted.

Characteristics of Café-au-lait Macules and their Association with the Neurofibromatosis type I Genotype in a Cohort of Greek Children.

Cafe-au-lait macules are the most distinctive clinical finding in neurofibromatosis type I. The aim of this prospective study of Greek children diagnosed with neurofibromatosis type I was to describe the dermatological phenotype and to analyse the characteristics of cafe-au-lait macules and their association with genotype. Pigment intensity and melatonin content of cafe-au-lait macules were measured with a narrowband spectrophotometer. A total of 63 children aged 6 months to 16 years old were studied. Mean melanin content varied, both among patients, and within each patient (p < 0.001). Females had a higher number of cafe-au-lait macules than did males (p = 0.025), and the melanin content of cafe-au-lait macules was lower in females than males (p < 0.001). Patients with protein-truncating variants in the neurofibromatosis type I gene had higher melanin content of cafe-au-lait macules than other types of genetic variants t (55) = 2.196, p = 0.032. Plexiform neurofibromas were also detected in the majority of patients with protein- truncating variants, while juvenile xanthogranulomas were detected equally in patients with protein-truncating and non-protein-truncating variants. In conclusion, cafe-au-lait macules with high melatonin content are associated with patients carrying non-protein-truncating variants. Therefore, measurement of cafe-au-lait macule pigment intensity might provide useful information for initial assessment of patients with neurofibromatosis type I and the severity of their future phenotype.

McCune-Albright Syndrome: A Case Report and Review of Literature.

McCune-Albright syndrome (MAS) is a rare sporadic condition defined by the classic triad of fibrous dysplasia of bone, café au lait skin macules, and hyperfunctioning endocrinopathies. The molecular basis of MAS has been ascribed to the post-zygotic somatic gain-of-function mutations in the GNAS gene, which encodes the alpha subunit of G proteins, leading to constitutive activation of several G Protein-Coupled Receptors (GPCRs). The co-occurrence of two of the above-mentioned cardinal clinical manifestations sets the diagnosis at the clinical level. In this case report, we describe a 27-month-old girl who presented with gonadotropin-independent precocious puberty secondary to an estrogen-secreting ovarian cyst, a café au lait skin macule and growth hormone, and prolactin excess, and we provide an updated review of the scientific literature on the clinical features, diagnostic work-up, and therapeutic management of MAS.

Stress and Well-Being of Greek Primary School Educators: A Cross-Sectional Study.

The teaching profession has always been challenging, while for various reasons the magnitude of observed stress in teachers has been continually growing over time. This study was conducted to demonstrate the relevance of stress in this professional group and to generate evidence for the benefit of primary school teachers and, indirectly, their pupils. To this end, we examined a large number of school teachers in a descriptive cross-sectional study. The survey comprised 786 primary school instructors aged 21 to 65 years, 646 women (82.2%) and 140 males (17.8%), and was performed from March to October 2022. Participants were asked about their gender, age, marital status, place of domicile, satisfaction with their income, whether their income met their needs, number of children, whether they cared for a person with a disability, work experience, alcohol use, eating patterns, and their height and weight for computation of their Body Mass Index (BMI). The survey included the Teacher Subjective Well-being Questionnaire (TSWQ), the Perceived Stress Scale (PSS), the Healthy Lifestyle and Personal Control Questionnaire (HLPCQ), and the Pittsburgh Sleep Quality Index (PSQI). The results showed that there were significant differences between the two sexes in age, marital status, work experience, smoking, alcohol use, and eating breakfast. Furthermore, there were significant differences between the two sexes in BMI, PSS Total, Dietary Health Choice, Harm Avoidance and Total HLPCQ. The variance of PSS Total was predicted by Sex, Teacher Efficacy, Total PSQI, Dietary Health Choice, organized physical exercise, social support and mental control, and Total HLPCQ. Between teacher efficacy, school connectedness, teacher well-being, organized physical exercise, social support and mental control, Total HLPCQ and PSS Total, the correlation coefficients were negative and significant at the <0.05 level. Between Total PSQI and PSS Total, the correlation coefficient was positive and significant at the <0.05 level. Between teacher efficacy, school connectedness and teacher well-being, organized physical exercise, social support and mental control, Total HLPCQ and Total PSQI, the correlation coefficients were negative and significant at the <0.05 level. In summary, we demonstrated that Greek primary school teachers experience significant stress, which is intertwined with their way of life, and reflected in significant decreases in their sense of well-being, quality of sleep, and overall life satisfaction, as well as in their standards of teaching.

International Consensus Guideline on Small for Gestational Age: Etiology and Management From Infancy to Early Adulthood.

This International Consensus Guideline was developed by experts in the field of small for gestational age (SGA) of 10 pediatric endocrine societies worldwide. A consensus meeting was held and 1300 articles formed the basis for discussions. All experts voted about the strengths of the recommendations. The guideline gives new and clinically relevant insights into the etiology of short stature after SGA birth, including novel knowledge about (epi)genetic causes. Further, it presents long-term consequences of SGA birth and also reviews new treatment options, including treatment with gonadotropin-releasing hormone agonist (GnRHa) in addition to growth hormone (GH) treatment, as well as the metabolic and cardiovascular health of young adults born SGA after cessation of childhood GH treatment in comparison with appropriate control groups. To diagnose SGA, accurate anthropometry and use of national growth charts are recommended. Follow-up in early life is warranted and neurodevelopment evaluation in those at risk. Excessive postnatal weight gain should be avoided, as this is associated with an unfavorable cardiometabolic health profile in adulthood. Children born SGA with persistent short stature < -2.5 SDS at age 2 years or < -2 SDS at 3 to 4 years of age, should be referred for diagnostic workup. In case of dysmorphic features, major malformations, microcephaly, developmental delay, intellectual disability, and/or signs of skeletal dysplasia, genetic testing should be considered. Treatment with 0.033 to 0.067 mg GH/kg/day is recommended in case of persistent short stature at age of 3 to 4 years. Adding GnRHa treatment could be considered when short adult height is expected at pubertal onset. All young adults born SGA require counseling to adopt a healthy lifestyle.

Nocturnal oximetry parameters as predictors of sleep apnea severity in resource-limited settings.

Nocturnal oximetry is an alternative modality for evaluating obstructive sleep apnea syndrome (OSAS) severity when polysomnography is not available. The Oxygen Desaturation (≥3%) Index (ODI3) and McGill Oximetry Score (MOS) are used as predictors of moderate-to-severe OSAS (apnea-hypopnea index-AHI >5 episodes/h), an indication for adenotonsillectomy. We hypothesised that ODI3 is a better predictive parameter for AHI >5 episodes/h than the MOS. All polysomnograms performed in otherwise healthy, snoring children with tonsillar hypertrophy in a tertiary hospital (November 2014 to May 2019) were analysed. The ODI3 and MOS were derived from the oximetry channel of each polysomnogram. Logistic regression was applied to assess associations of ODI3 or MOS (predictors) with an AHI >5 episodes/h (primary outcome). Receiver operating characteristic (ROC) curves and areas under ROC curves were used to compare the ODI3 and MOS as predictors of moderate-to-severe OSAS. The optimal cut-off value for each oximetry parameter was determined using Youden's index. Polysomnograms of 112 children (median [interquartile range] age 6.1 [3.9-9.1] years; 35.7% overweight) were analysed. Moderate-to-severe OSAS prevalence was 49.1%. The ODI3 and MOS were significant predictors of moderate-to-severe OSAS after adjustment for overweight, sex, and age (odds ratio [OR] 1.34, 95% confidence interval [CI] 1.19-1.51); and OR 4.10, 95% CI 2.06-8.15, respectively; p < 0.001 for both). Area under the ROC curve was higher for the ODI3 than for MOS (0.903 [95% CI 0.842-0.964] versus 0.745 [95% CI 0.668-0.821]; p < 0.001). Optimal cut-off values for the ODI3 and MOS were ≥4.3 episodes/h and ≥2, respectively. The ODI3 emerges as preferable or at least a complementary oximetry parameter to MOS for detecting moderate-to-severe OSAS in snoring children when polysomnography is not available.

Frequencies of pathogenic CFTR variants in Greek cystic fibrosis patients with allergic bronchopulmonary aspergillosis and Aspergillus fumigatus chronic colonization: A retrospective cohort study.

INTRODUCTION: The clinical spectrum of Aspergillus fumigatus diseases in cystic fibrosis (CF) patients, including allergic bronchopulmonary aspergillosis (ABPA) and Aspergillus fumigatus chronic colonization, has recently gained attention due to its association with the progression of lung disease. Our aim was to examine whether there is a difference on pathogenic variant frequencies of the CFTR gene between CF patients with ABPA and those with A. fumigatus chronic colonization. MATERIAL AND METHODS: Greek CF patients diagnosed with ABPA and/or A. fumigatus chronic colonization were grouped according to their CFTR genotype. Patients with "minimal" CFTR function were defined as carrying a combination of class I or II pathogenic variants, while patients with "residual" function as carrying at least one class III, IV, V or VI pathogenic variant. RESULTS: Fifty-four CF patients were included and all except one were defined as having "minimal" CFTR function. Among the 108 CFTR alleles, 69 (63.9%) of pathogenic variants belonged to class II, and 32 (29.6%) to class I. Five patients had a history of both ABPA and A. fumigatus chronic colonization. No significant difference was detected among patients diagnosed only with ABPA (n = 29) and those who had only a positive history of A. fumigatus chronic colonization (n = 20). The median age of ABPA diagnosis was significantly lower than the median age of A. fumigatus chronic colonization (P = 0.011), while no significant difference was detected on median FEV1% predicted. DISCUSSION: No significant differences were detected in the type of CFTR pathogenic variants among patients with ABPA and those with A. fumigatus colonization. Similar studies should be performed in larger CF populations of different ethnic origin to further confirm our results.

Highlighting the trajectory from intrauterine growth restriction to future obesity.

During the last decades several lines of evidence reported the association of an adverse intrauterine environment, leading to intrauterine restriction, with future disease, such as obesity and metabolic syndrome, both leading to increased cardiovascular and cancer risk. The underlying explanation for this association has firstly been expressed by the Barker's hypothesis, the "thrifty phenotype hypothesis". According to this hypothesis, a fetus facing an adverse intrauterine environment adapts to this environment through a reprogramming of its endocrine-metabolic status, during the crucial window of developmental plasticity to save energy for survival, providing less energy and nutrients to the organs that are not essential for survival. This theory evolved to the concept of the developmental origin of health and disease (DOHaD). Thus, in the setting of an adverse, f. ex. protein restricted intrauterine environment, while the energy is mainly directed to the brain, the peripheral organs, f.ex. the muscles and the liver undergo an adaptation that is expressed through insulin resistance. The adaptation at the hepatic level predisposes to future dyslipidemia, the modifications at the vascular level to endothelial damage and future hypertension and, overall, through the insulin resistance to the development of metabolic syndrome. All these adaptations are suggested to take place through epigenetic modifications of the expression of genes without change of their amino-acid sequence. The epigenetic modifications leading to future obesity and cardiovascular risk are thought to induce appetite dysregulation, promoting food intake and adipogenesis, facilitating obesity development. The epigenetic modifications may even persist into the next generation even though the subsequent generation has not been exposed to an adverse intrauterine environment, a notion defined as the "transgenerational transfer of environmental information". As a consequence, if the increased public health burden and costs of non-communicable chronic diseases such as obesity, hypertension, metabolic syndrome and type 2 diabetes have to be minimized, special attention should be laid to the healthy lifestyle habits of women of reproductive age, including healthy diet and physical activity to be established long before any pregnancy takes place in order to provide the best conditions for both somatic and mental health of future generations.

Cytotoxic Effect of Rosmarinus officinalis Extract on Glioblastoma and Rhabdomyosarcoma Cell Lines.

Rosmarinus officinalis is a well-studied plant, known for its therapeutic properties. However, its biological activity against several diseases is not known in detail. The aim of this study is to present new data regarding the cytotoxic activity of a hydroethanolic extract of Rosmarinus officinalis on glioblastoma (A172) and rhabdomyosarcoma (TE671) cancer cell lines. The chemical composition of the extract is evaluated using liquid chromatography combined with time-of-flight mass spectrometry, alongside its total phenolic content and antioxidant activity. The extract showed a promising time- and dose-dependent cytotoxic activity against both cell lines. The lowest IC50 values for both cell lines were calculated at 72 h after treatment and correspond to 0.249 ± 1.09 mg/mL for TE671 cell line and 0.577 ± 0.98 mg/mL for A172 cell line. The extract presented high phenolic content, equal to 35.65 ± 0.03 mg GAE/g of dry material as well as a strong antioxidant activity. The IC50 values for the antioxidant assays were estimated at 12.8 ± 2.7 µg/mL (DPPH assay) and 6.98 ± 1.9 µg/mL (ABTS assay). The compound detected in abundance was carnosol, a phenolic diterpene, followed by the polyphenol rosmarinic acid, while the presence of phenolic compounds such as rhamnetin glucoside, hesperidin, cirsimaritin was notable. These preliminary results suggest that R. officinalis is a potential, alternative source of bioactive compounds to further examine for abilities against glioblastoma and rhabdomyosarcoma.

Whole Exome Sequencing Points towards a Multi-Gene Synergistic Action in the Pathogenesis of Congenital Combined Pituitary Hormone Deficiency.

Combined pituitary hormone deficiency (CPHD) is characterized by deficiency of growth hormone and at least one other pituitary hormone. Pathogenic variants in more than 30 genes expressed during the development of the head, hypothalamus, and/or pituitary have been identified so far to cause genetic forms of CPHD. However, the etiology of around 85% of the cases remains unknown. The aim of this study was to unveil the genetic etiology of CPHD due to congenital hypopituitarism employing whole exome sequencing (WES) in two newborn patients, initially tested and found to be negative for PROP1, LHX3, LHX4 and HESX1 pathogenic variants by Sanger sequencing and for copy number variations by MLPA. In this study, the application of WES in these CPHD newborns revealed the presence of three different heterozygous gene variants in each patient. Specifically in patient 1, the variants BMP4; p.Ala42Pro, GNRH1; p.Arg73Ter and SRA1; p.Gln32Glu, and in patient 2, the SOX9; p.Val95Ile, HS6ST1; p.Arg306Gln, and IL17RD; p.Pro566Ser were identified as candidate gene variants. These findings further support the hypothesis that CPHD constitutes an oligogenic rather than a monogenic disease and that there is a genetic overlap between CPHD and congenital hypogonadotropic hypogonadism.

Molecular and clinical profile of patients referred as Noonan or Noonan-like syndrome in Greece: a cohort of 86 patients.

Noonan syndrome (NS) is an autosomal dominant disorder characterized by clinical and genetic heterogeneity. It belongs to a wider group of pathologies, known as Rasopathies, due to the implication of genes encoding components of the Ras/MAPK signalling pathway. Recording the genetic alterations across populations helps assessing specific features to specific genes which is essential for better disease's recognition, prognosis and monitoring. Herein, we report the clinical and molecular data of a Greek cohort comprising of 86 NS or NS-like patients admitted at a single tertiary Centre in Athens, Greece. The analysis was performed using Sanger and next-generation sequencing, comprising 14 different genes. The mutational rates of the confirmed NS-associated genes in the Greek NS population are as follows: PTPN11 32.5%; RIT1 5.8%; SOS1 4.7%; BRAF 1.2%; CBL 1.2%; KRAS 1.2%; MAP2K1 1.2%; RAF1 1.2%; SHOC2 1.2%, corresponding to 50% of positivity in total NS population. The genotype-phenotype analysis showed statistically significant differences in craniofacial dysmorphisms (p = 0.005) and pulmonary valve stenosis (PS) (p < 0.001) frequencies between patients harbouring a pathogenic variant and patients without pathogenic variant in any of the tested genes. Patients with at least a pathogenic variant had 6.71 times greater odds to develop PS compared to pathogenic variant-negative patients (OR = 6.71, 95%; CI = (2.61, 17.27)). PTPN11 positive patients showed higher frequency of epicanthal folds (p = 0.004), ptosis (p = 0.001) and coarseness (p = 0.001) and lower frequency of neurological findings (p = 0.006), compared to patients carrying pathogenic variants in other genes. CONCLUSION: Craniofacial dysmorphism and PS prevail among pathogenic variant positive compared to pathogenic variant negative NS and NS-like patients while neurological defects are less common in PTPN11-affected NS patients compared to patients harbouring pathogenic variants in other genes. The significant prevalence of the Ras/MAPK pathogenic variants (17.4%), other than PTPN11, in Greek NS patients, highlights the necessity of a wider spectrum of molecular diagnosis. WHAT IS KNOWN: • Noonan syndrome (NS) has been associated with pathogenic variants in molecules-components of the Ras/MAPK pathway. • Clinical and genetic description of NS patients worldwide helps establishing personalized monitoring. WHAT IS NEW: • NS and NS-like mutational rate in Greece reaches 50% with pathogenic variants identified mostly in PTPN11 (32.5%), RIT1 (6%) and SOS1 (4.7%) genes. • The risk for pulmonary stenosis increases 6.71-fold in NS patients with a pathogenic variant compared to patients without genetic alterations.

An In Vitro Study of Saffron Carotenoids: The Effect of Crocin Extracts and Dimethylcrocetin on Cancer Cell Lines.

Crocus sativus L. has various pharmacological properties, known for over 3600 years. These properties are attributed mainly to biologically active substances, which belong to the terpenoid group and include crocins, picrocrocin and safranal. The aim of the current work was to examine the effects of crocins (CRCs) and their methyl ester derivate dimethylcrocetin (DMCRT) on glioblastoma and rhabdomyosarcoma cell lines, in terms of cytotoxicity and gene expression, implicated in proapoptotic and cell survival pathways. Cell cytotoxicity was assessed with Alamar Blue fluorescence assay after treatment with saffron carotenoids for 24, 48 and 72 h and concentrations ranging from 22.85 to 0.18 mg/mL for CRCs and 11.43 to 0.09 mg/mL for DMCRT. In addition, BAX, BID, BCL2, MYCN, SOD1, and GSTM1 gene expression was studied by qRT-PCR analysis. Both compounds demonstrated cytotoxic effects against glioblastoma and rhabdomyosarcoma cell lines, in a dose- and time-dependent manner. They induced apoptosis, via BAX and BID upregulation, MYCN and BCL-2, SOD1, GSTM1 downregulation. The current research denotes the possible anticancer properties of saffron carotenoids, which are considered safe phytochemicals, already tested in clinical trials for their health promoting properties.

Biophysical Studies and In Vitro Effects of Tumor Cell Lines of Cannabidiol and Its Cyclodextrin Inclusion Complexes.

Phytocannabinoids possess anticancer properties, as established in vitro and in vivo. However, they are characterized by high lipophilicity. To improve the properties of cannabidiol (CBD), such as solubility, stability, and bioavailability, CBD inclusion complexes with cyclodextrins (CDs) might be employed, offering targeted, faster, and prolonged CBD release. The aim of the present study is to investigate the in vitro effects of CBD and its inclusion complexes in randomly methylated ß-CD (RM-ß-CD) and 2-hyroxypropyl-ß-CD (HP-ß-CD). The enhanced solubility of CBD upon complexation with CDs was examined by phase solubility study, and the structure of the inclusion complexes of CBD in 2,6-di-O-methyl-ß-CD (DM-ß-CD) and 2,3,6-tri-O-methyl-ß-CD (TM-ß-CD) was determined by X-ray crystallography. The structural investigation was complemented by molecular dynamics simulations. The cytotoxicity of CBD and its complexes with RM-ß-CD and HP-ß-CD was tested on two cell lines, the A172 glioblastoma and TE671 rhabdomyosarcoma cell lines. Methylated ß-CDs exhibited the best inclusion ability for CBD. A dose-dependent effect of CBD on both cancer cell lines and improved efficacy of the CBD-CDs complexes were verified. Thus, cannabinoids may be considered in future clinical trials beyond their palliative use as possible inhibitors of cancer growth.

Ovarian insufficiency and secondary amenorrhea in a patient with a novel variant within GDF9 gene.

OBJECTIVE: Premature ovarian insufficiency is a heterogeneous condition that can be caused by several factors, such as genetic, environmental, etc. and represents one of the main causes of female infertility. One of the genes implicated is GDF9, which encodes a member of the transforming growth factor-beta superfamily that participates in the coordination of somatic cell activity, female fertility, including folliculogenesis, and oocyte maturation. Damaging variants in GDF9-encoded growth factors can cause the production of inhibin, perturb oocyte granulosa cell microenvironments, and obstruct follicle development. A novel GDF9 variant is herein reported to consolidate the role of GDF9 in ovarian function and female fertility. METHODS: A 38-year-old female was referred for the investigation of secondary amenorrhea. Eventually, she was referred for genetic evaluation whereby conventional karyotyping and Fragile-X molecular testing were normal. Whole Exome Sequencing was performed, followed by targeted Sanger sequencing in all family members for variant confirmation and evaluation. RESULTS: In this study we report a patient presenting with secondary amenorrhea due to premature ovarian failure and a pituitary lesion with radiological characteristics compatible with a Rathke cyst or a macroadenoma, residing between the adenohypophysis and neurohypophysis. Whole Exome Sequencing revealed a novel heterozygous stoploss variant c.1364A>C, p.(*455Serext*8) in the GDF9 gene. CONCLUSIONS: Should the predicted elongated GDF9 protein and differentially configurated GDF9 mature protein molecule form unstable dimers, rapid proteolytic degradation may take place and inhibit homo/heterodimer formation.

Mediterranean Diet as an Antioxidant: The Impact on Metabolic Health and Overall Wellbeing.

It has been established, worldwide, that non-communicable diseases such as obesity, diabetes, metabolic syndrome, and cardiovascular events account for a high percentage of morbidity and mortality in contemporary societies. Several modifiable risk factors, such as sedentary activities, sleep deprivation, smoking, and unhealthy dietary habits have contributed to this increase. Healthy nutrition in terms of adherence to the Mediterranean diet (MD), rich in fruits, legumes, vegetables, olive oil, herbs, spices, and high fiber intake may contribute to the decrease in this pandemic. The beneficial effects of the MD can be mainly attributed to its numerous components rich in anti-inflammatory and antioxidant properties. Moreover, the MD may further contribute to the improvement of reproductive health, modify the risk for neurodegenerative diseases, and protect against depression and psychosocial maladjustment. There is also evidence highlighting the impact of healthy nutrition in female people on the composition of the gut microbiota and future metabolic and overall health of their offspring. It is therefore important to highlight the beneficial effects of the MD on metabolic, reproductive, and mental health, while shaping the overall health of future generations. The beneficial effects of MD can be further enhanced by increased physical activity in the context of a well-balanced healthy lifestyle.

Cognitive function of children and adolescent survivors of acute lymphoblastic leukemia: A meta-analysis.

Pediatric cancer and its treatment may have an impact on the neurocognitive functions of childhood cancer survivors (CCS). The aim of the present meta-analysis was to compare the intelligence quotient (IQ) scores between CCS of acute lymphoblastic leukemia (ALL) and controls. A comprehensive electronic search identified original research articles that reported scores of the Wechsler Intelligence Scale (WISC; WISC-III, WISC-IV and WISC-R) for children and adolescents, aged 6-16 years at evaluation, survivors of ALL and healthy controls. The included CCS had completed anticancer treatment and were in remission at the time of assessment. A total of 16 studies were included in the meta-analysis, out of 128 extracted studies, and involved a total of 1,676 children and adolescents: 991 CCS (ALL) and 685 healthy controls. Among the studies, a random effects model revealed a moderate estimate of effect size [standardized mean difference (SMD), -0.78; 95% CI, -1.05 to -0.50], indicating that the WISC scores for total IQ were significantly lower in the CCS than in the controls. The mean total IQ range was 85.2-107.2 in the CCS and 88.4-114.1 in the controls. The difference in the mean total IQ between controls and CCS ranged from -13.8 to 20.6. As regards the WISC scores for verbal IQ, 11 studies were included. A random effects model revealed a moderate estimate of effect size (SMD, -0.71; 95% CI, -1.05 to -0.38), indicating that the WISC scores for verbal IQ were significantly lower in the CCS than in the controls. Among the 9 studies that had available data for performance IQ scores, a fixed effect model revealed a moderate estimate of effect size (SMD, -0.80; 95% CI, -1.09 to -0.52), indicating that the WISC scores for performance IQ were significantly lower in the CCS than in the controls. As the survival rates of children and adolescents with ALL are steadily increasing, regular, lifelong follow-up for neurocognitive late effects is imperative in order to improve their education and employment prospects and overall, their quality of life.

Case Report: A Novel Synonymous ARPC1B Gene Mutation Causes a Syndrome of Combined Immunodeficiency, Asthma, and Allergy With Significant Intrafamilial Clinical Heterogeneity.

Recently, a novel syndrome of combined immune deficiency, infections, allergy, and inflammation has been attributed to mutations in the gene encoding actin-related protein 2/3 complex subunit 1B (ARPC1B), which is a key molecule driving the dynamics of the cytoskeleton. Homozygous mutations in the ARPC1B gene have been found to result in the disruption of the protein structure and cause an autosomal recessive syndrome of combined immune deficiency, impaired T-cell migration and proliferation, increased levels of immunoglobulin E (IgE) and immunoglobulin A (IgA), and thrombocytopenia. To date, only a few individuals have been diagnosed with the ARPC1B deficiency syndrome worldwide. In this case series, we report the wide spectrum of phenotype in 3 siblings of a consanguineous family from Afghanistan with a novel homozygous synonymous pathogenic variant c.783G>A, p. (Ala261Ala) of the ARPC1B gene that causes a similar syndrome but no thrombocytopenia. Targeted RNA studies demonstrated that the variant affects the splicing process of mRNA, resulting in a marked reduction of the levels of primary (normal) RNA transcript of the ARPC1B gene in the affected patients and likely premature termination from the abnormally spliced mRNA. The next generation sequencing (NGS) studies facilitated the diagnosis of this rare combined immunodeficiency and led to the decision to treat the affected patients with hematopoietic cell transplant (HCT) from an human leukocyte antigen (HLA)-matched healthy sibling.

Detection of hepatocyte nuclear factor 4A(HNF4A) gene variant as the cause for congenital hyperinsulinism leads to revision of the diagnosis of the mother.

OBJECTIVES: Congenital Hyperinsulinism (CHI) is the most common cause of persistent hypoketotic hypoglycaemia in neonates and infants. It is a genetic disorder with both familial and sporadic forms. CASE PRESENTATION: In this study, we examined two unrelated infants of diabetic mothers (IDMs) presented with HH. DNA sequencing (Sanger and NGS panel) identified pathogenic variants of the Hepatocyte Nuclear Factor 4A (HNF4A) gene in both families. Pathogenic variants of HNF4A gene are reported to cause HH in the newborn period and Maturity Onset Diabetes of the Young (MODY) later in life. The diagnosis of MODY was made in retrospect for the two mothers, thus improving the management of their diabetes. CONCLUSION: Genetic testing for CHI is strongly recommended if neonatal hypoglycemia persists. A family history of MODY or presumed type II diabetes can support that the affected gene is HNF4A.

ROHHAD syndrome - A still unrecognized cause of childhood obesity: report of three cases.

Objectives Rapid-onset obesity with hypoventilation, hypothalamic dysfunction, and autonomic dysregulation (ROHHAD) is a rare, potentially fatal, pediatric syndrome. Case presentations We describe three cases of ROHHAD-syndrome in Greece. The main and earliest symptom was the excessive and rapid weight gain at 5, 2, and 3 years of age. Years after the onset of obesity, the patients developed hypothalamic dysfunction with various endocrinological abnormalities (at 9, 8, and 6.8 years, respectively), autonomic dysregulation and finally, alveolar hypoventilation (at 14.6, 8, and 7.8 years, respectively), leading to the diagnosis of ROHHAD-syndrome. Conclusions The rarity of the syndrome, the variable symptoms' presentation, and the lack of specific diagnostic tests could explain why no previous cases have been reported from our country. The rapid onset of obesity was underestimated, and the patients were misdiagnosed with other more common obesity syndromes. Therefore, we propose a questionnaire to help physicians identify patients with ROHHAD-syndrome.

Partial empty sella syndrome, GH deficiency and transient central adrenal insufficiency in a patient with NF1.

PURPOSE: To describe the case of a 9-year-old male patient with neurofibromatosis type 1 (NF1), partial empty sella (PES), transient central adrenal insufficiency (CAI) and growth hormone (GH) deficiency (GHD) treated with recombinant GH (rGH). METHODS: The diagnosis of GHD was established upon peak GH response <10 ng/mL following glucagon and clonidine stimulation tests. CAI was diagnosed when peak cortisol response was <18 µg/dL following 1 µg Synacthen test (ST) with normal ACTH levels. RESULTS: The diagnosis of NF1 was made at the age of 1.5 year. The patient first attended our Department at the age of 4.5 years. He presented with short stature (height: 95 cm < 3rd percentile), macrocephaly, frontal bossing, café-au-lait spots and bilateral proptosis. His growth rate (GR) initially was 5.3 cm/year. Brain/pituitary MRI showed T2-hyperintensities typical for NF1 and PES with reduced pituitary gland height (3 mm). The pituitary function tests revealed GHD. During follow-up his imaging findings remained unchanged, while his GR decelerated. He was started on rGH at the age of 8.5 years. Within the following year he grew 8.7 cm in height and could preserve a normal GR thereafter. At the age of 10.3 years, he was diagnosed with CAI (maximum cortisol response post-1 µg ST: 13.1 µg/dL). Ηe received hydrocortisone for 1 year. A repeat 1 µg ST off hydrocortisone showed normal cortisol response. During follow-up, brain MRI findings remained stable, while his pituitary demonstrated normal size and signal intensity. CONCLUSION: Empty sella and hypopituitarism may occur in the context of NF1. Short stature may be associated with GHD in the absence of intrasellar masses in affected individuals. Lifelong endocrine follow-up is recommended for all NF1 patients.
