Early-onset dysphagia and severe neurodevelopmental disorder as early signs in a patient with two novel variants in NARS1: a case report and brief review of the literature.

Aminoacyl-tRNA synthetases (ARSs) aminoacylate tRNA molecules with their cognate amino acid, enabling information transmission and providing substrates for protein biosynthesis. They also take part in nontranslational functions, mediated by the presence of other proteins domains. Mutations in ARS genes have been described as responsive to numerous factors, including neurological, autoimmune, and oncological. Variants of the ARS genes, both in heterozygosity and homozygosity, have been reported to be responsible for different pathological pictures in humankind. We present the case of a patient referred in infancy for failure to thrive and acquired microcephaly (head circumference: -5 SD). During follow-up we highlighted: dysphagia (which became increasingly severe until it became incompatible with oral feeding, with gastrostomy implantation, resulting in resolution of feeding difficulties), strabismus, hypotonia. NCV (Nerve Conduction Velocity) showed four limbs neuropathy, neurophysiological examination performed at 2 years of age mainly sensory and demyelinating. Exome sequencing (ES) was performed, detecting two novel compound heterozygous variants in the NARS1 gene (OMIM *108410): NM_004539:c.[662 A > G]; [1155dup], p.[(Asn221Ser)]; [(Arg386Thrfs*19)], inherited from mother and father respectively. In this article, we would like to focus on the presence of progressive dysphagia and severe neurodevelopmental disorder, associated with two novel variants in the NARS1 gene.

Defense style and psychopathology in oncological patients: a preliminary report.

INTRODUCTION: Previous studies shows that 30-40% of oncological and hematological patients report symptoms of distress compatible with a psychiatric disorder. The use of various and mostly unconscious defense mechanisms is implemented to cope with increased suffering after a cancer diagnosis. In this preliminary report, we explored the presence of defense mechanisms and their associations with psychopathological dimensions in a sample of late-stage cancer patients without history of psychiatric disorders. METHODS: We recruited 50 patients (28 females, 18-64 years old) with cancer diagnosis without prior history of any substance use disorder or psychiatric disorders. All participants were given the following self-report questionnaires: the Symptom Checklist 90 (SCL-90) and the 40-item version of the Defense Style Questionnaire (DSQ-40). RESULTS: In our study we demonstrated significant psychiatric distress in a third of our patients (defined as SCL-90 ≥2 points). A Pearson correlation analysis on all patients shows that psychotic defense styles were correlated with hostility, obsessive-compulsive, anxiety, somatization, interpersonal sensitivity, and psychoticism, while neurotic defense styles correlated with somatization. DISCUSSION AND CONCLUSION: Our results are in line with previous findings showing that one third of cancer patients suffers from a psychiatric disorder. Moreover, we found that somatization correlates with both psychotic and neurotic defense mechanism styles. This demonstrates the importance of assessing oncological patients coping mechanisms to achieve best possible treatment.
