Developmental Profile of Social Communication: Findings in Typical Developing Greek Children.

OBJECTIVES: The Developmental Profile of Social Communication (DPSC) is based on the communication and language development in children with social communication difficulties. DPSC facilitates understanding of the challenges these children face in social interaction, communication, and linguistic development. It utilizes clinician and parent responses to build the developmental profiles of individuals. The profile allows clinicians to determine the therapeutic goals for improved cooperation and communication in various contexts. In addition, it provides insight into the parents' perspective. The aim of this study is to present the preliminary results of the DPSC in typically developing Greek children. METHODS: The DPSC, a 112-item questionnaire, was administered to 357 parents of typically developing children aged 2-7.5 years using a 3-scale rating of answers. It was applied electronically via Google forms, and parents were able to ask for clarification on questions. All answers were categorized and then analyzed under independent variables. RESULTS: Descriptive and hypothesis testing were used to summarize participant characteristics and performance. Findings suggest that children >7.5 years tended to develop most of the rated skills of DPSC adequately. CONCLUSIONS: It was determined that the DPSC questionnaire is an easily administered tool that enables the evaluation of the social communication abilities of children of different ages.

Chronic seronegative spondyloarthropathy following acute Mycoplasma pneumoniae infection in a human leukocyte antigen B27-positive patient: a case report.

BACKGROUND: We report a case of a 30-year-old patient who presented with acute Mycoplasma pneumoniae infection that was complicated by reactive arthritis and asymmetric proximal myopathy and progressed to chronic spondyloarthropathy. Reactive arthritis and sacroiliitis are unusual extrapulmonary manifestations of M. pneumoniae infection, which is a common condition. CASE PRESENTATION: A 30-year-old Greek previously healthy man presented to our emergency department with fever, progressively worsening bilateral lower limb weakness, and asymmetric oligoarthritis. Our diagnosis was based on a positive polymerase chain reaction test for M. pneumoniae using blood and cerebrospinal fluid and magnetic resonance imaging findings that suggested sacroiliitis. Our patient was also found to be human leukocyte antigen B27 positive. His infection was successfully treated with a 14-day course of doxycycline; the arthritis was treated with naproxen and corticosteroids. His arthritis, which restricted his mobility, improved progressively, and he was discharged without any neurological symptoms. CONCLUSIONS: In our case, an acute M. pneumoniae infection eventually progressed to chronic spondyloarthropathy. In our patient, M. pneumoniae infection may represent a random event, or it might be a necessary factor for the development of reactive arthritis, asymmetric proximal myopathy, and sacroiliitis, always in combination with the appropriate genetic background. Extrapulmonary manifestations of M. pneumoniae may occur even in the complete absence of respiratory symptoms, and the diagnosis of unusual complications, such as reactive arthritis, requires high clinical suspicion and extensive investigation.

Lessons From a Diabetes Clinic: Achieving Glycemic Goals and Clinical Use of Antidiabetic Agents in Patients With Type 2 Diabetes.

The proportion of patients with type 2 diabetes who achieve their glycemic goals remains low. We examined medical records and A1C results from patient visits to our referral diabetes center between 21 March to 20 July 2018. After stratifying patients into four groups-monotherapy, dual therapy, triple therapy, or insulin therapy-we found that the target A1C of ≤7.0% was achieved by 86% of patients and that A1C was uniformly low across the treatment categories. Our individualized approach, which included high use of glucagon-like peptide-1 receptor agonists and low use of sulfonylureas, may have contributed to these results.

Crystal growth rates in supercooled atomic liquid mixtures.

Crystallization is a fundamental process in materials science, providing the primary route for the realization of a wide range of new materials. Crystallization rates are also considered to be useful probes of glass-forming ability1-3. At the microscopic level, crystallization is described by the classical crystal nucleation and growth theories4,5, yet in general solid formation is a far more complex process. In particular, the observation of apparently different crystal growth regimes in many binary liquid mixtures greatly challenges our understanding of crystallization1,6-12. Here, we study by experiments, theory and computer simulations the crystallization of supercooled mixtures of argon and krypton, showing that crystal growth rates in these systems can be reconciled with existing crystal growth models only by explicitly accounting for the non-ideality of the mixtures. Our results highlight the importance of thermodynamic aspects in describing the crystal growth kinetics, providing a substantial step towards a more sophisticated theory of crystal growth.

Euglycemic Ketoacidosis in Spinal Muscular Atrophy.

Euglycemic ketoacidosis is defined by the triad of high anion gap acidosis, increased plasma ketones, and the absence of hyperglycemia. Apart from diabetes mellitus, the disorder may occur in prolonged fasting, excessive alcohol consumption, pregnancy, and inborn errors of metabolism. Here, we highlight the diagnosis of euglycemic ketoacidosis in a pediatric nondiabetic patient with spinal muscular atrophy (SMA) type 1 (Werdnig-Hoffmann disease), who, subsequently to her postoperative admission to the intensive care unit following a spinal surgery, developed high anion gap metabolic acidosis. We discuss the pathophysiology of acid-base disorders in SMA, along with the glucose and fatty acids metabolism, the necessary knowledge for medical practitioners.

Invasive Aspergillosis in Children: Update on Current Guidelines.

Invasive aspergillosis (IA) is an important cause of infectious morbidity and mortality in immunocompromised paediatric patients. Despite improvements in diagnosis, prevention, and treatment, IA is still associated with high mortality rates. To address this issue, several international societies and organisations have proposed guidelines for the management of IA in the paediatric population. In this article, we review current recommendations of the Infectious Diseases Society of America, the European Conference on Infection in Leukaemia and the European Society of Clinical Microbiology and Infectious Diseases for the management and prevention of IA in children.

Shrinking of Rapidly Evaporating Water Microdroplets Reveals their Extreme Supercooling.

The fast evaporative cooling of micrometer-sized water droplets in a vacuum offers the appealing possibility to investigate supercooled water-below the melting point but still a liquid-at temperatures far beyond the state of the art. However, it is challenging to obtain a reliable value of the droplet temperature under such extreme experimental conditions. Here, the observation of morphology-dependent resonances in the Raman scattering from a train of perfectly uniform water droplets allows us to measure the variation in droplet size resulting from evaporative mass losses with an absolute precision of better than 0.2%. This finding proves crucial to an unambiguous determination of the droplet temperature. In particular, we find that a fraction of water droplets with an initial diameter of 6379±12 nm remain liquid down to 230.6±0.6 K. Our results question temperature estimates reported recently for larger supercooled water droplets and provide valuable information on the hydrogen-bond network in liquid water in the hard-to-access deeply supercooled regime.

Streptococcus thoraltensis Bacteremia: First Described Case as a Fever of Unknown Origin in Human.

Streptococcus thoraltensis has mainly been reported to cause infections in animals. Its clinical significance as a human pathogen has not yet been fully elucidated and needs further investigation. We describe here a case of bacteremia attributed to S. thoraltensis in a 55-year-old female patient admitted to our department due to fever of unknown origin. To the best of our knowledge, this is the first reported case of S. thoraltensis bacteremia in a human and the first reported case of S. thoraltensis as a cause of fever of unknown origin in human.

Relationship between ABO blood groups and head and neck cancer among Greek patients.

PURPOSE: We examined the association of ABO blood groups with the different types of head and neck cancers. METHODS: 195 diagnosed cases and 801 controls were selected from a Greek tertiary cancer center. Information regarding type of head and neck cancer and ABO blood group was collected and registered. RESULTS: The O blood group was found to be most prevalent followed by A, B and AB among the controls, whereas blood group A followed by O, B and AB was most prevalent among cancer patients. The difference among the distribution between the cases and controls was statistically significant in blood group A (p<0.05), whereas blood group A had 1.52-fold higher risk of developing head and neck cancer compared to people of other blood groups. CONCLUSIONS: Blood group A was found to be a potential risk factor for the development of head and neck cancers.

Reading the Mind in the Eyes Test (Children's Version): a comparison study between children with typical development, children with high-functioning autism and typically developed adults.

BACKGROUND/AIMS: One of psychology's challenges is to develop and evaluate sensitive tests in the area of social cognition. Yet, there are few available scales that can measure mild deficits in social understanding, especially for typically developing (TD) populations. The Reading the Mind in the Eyes Test (children's version) was translated and adapted for use in the Greek language [RMET-G (child)]. The aim of this study was to examine in the Greek language the qualitative and quantitative differences between TD youngsters and those with high-functioning autism (HFA), as well as the difference between TD children and TD adults. METHODS: An interview-based psychometric study was conducted. Participants completed the RMET-G (child), constituting 3 groups: TD children older than 8 years, children with HFA and TD adults. RESULTS: 103 participants completed the study. The results demonstrated that TD adults scored slightly higher than TD children, and children with HFA scored lower than their TD peers. Children with HFA, however, were able to recognize many of the pictures shown in the test. CONCLUSION: The results of this study, which were the first to be conducted in the Greek language, confirm findings of other studies in the literature conducted with the RMET in the English language.

Chemometric optimization of dispersive suspended microextraction followed by gas chromatography-mass spectrometry for the determination of polycyclic aromatic hydrocarbons in natural waters.

A dispersive suspended microextraction (DSME) method coupled with gas chromatography-mass spectrometry (GC-MS) was developed and validated for the simultaneous determination of ten polycyclic aromatic hydrocarbons in real water samples. The optimization of the method was achieved with a 2(7-4) Plackett-Burman design, while the significant factors were optimized using a central composite design (CCD). The parameters that were studied included the sample volume, organic solvent volume, extraction time, restoration time and organic solvent. The optimum experimental conditions for the proposed method comprised 4.3mL of the water sample, 93µL of toluene as the extraction solvent, a 104-s extraction time and a 10-min restoration time. The recoveries varied from 70 to 111%. Chrysene was the least recovered compound, while anthracene displayed the highest extraction efficiency. The analytical method (DSME) was shown to be linear (R(2)>0.993) over the studied range of concentrations, exhibiting satisfactory precision (RSD%<10.6%) and reaching limits of detection between 8 and 46ngL(-1).

Behçet's Disease, Associated Large Vessel Thrombosis, and Coexistent Thrombophilia: A Distinct Nosological Entity?

Behçet's disease (BD) represents a multisystemic disorder that combines features of immune-mediated diseases and autoinflammatory disorders. Even though it is recognized that every type or size of vessel can be affected in this disease, there is an inability to describe a coherent model that sufficiently explains the predilection of certain patients with BD for manifesting severe large vessel thrombosis. The inconsistent epidemiologic data and the complex genetic background of BD, along with the controversy of multiple international studies regarding the coexistence of thrombophilia in patients with BD and large vessel thrombosis, make us think that a percentage of these patients may actually suffer from a distinct clinical entity. The stimulus for this concept arose from the clinical observation of three male patients who were admitted to our clinic due to extended vena cava thrombosis. On the occasion of those clinically and laboratory resembling cases, we performed a literature review concerning the epidemiology of BD, associated thrombosis, and coexistent thrombophilic factors, in order to present some evidence, which sustains our hypothesis that certain patients with large vessel thrombosis, who share features of BD and coexistent thrombophilia, should actually be further investigated for the possibility of suffering from a distinct nosological entity.
