Evaluation of peritraumatic distress at the point of care: A cross-sectional study.

BACKGROUND: COVID-19 related peritraumatic distress has been investigated in the general population with contrasting results probably due to the perceived risk of developing COVID-19. Our study aims to investigate this condition in individuals with ascertained or probable SARS-CoV-2 exposure. METHODS: The Coronavirus Peritraumatic Distress Index (CPDI) was administered to people attending a COVID-19 point of care. The sample was stratified for perceived risk in SARS-CoV-2 positive cases, close contacts, case relatives, undergoing screening subjects, and symptomatic subjects. RESULTS: 1463 subjects participated, and with a mean CPDI Score of 28.2 (SD 16.9). CPDI Scores in SARS-CoV-2 positive cases were significantly higher than case relatives (p = 0.02). Multiple logistic regression revealed that having had work changes (p = 0.001), night sleep changes (p < 0.001), physical activity reduction (p = 0.002), alcohol consumption changes (p = 0.003), and at least one relative lost to COVID-19 (p < 0.001) independently predicted higher CPDI Scores. Male sex (p < 0.001), age ≥ 35 years (p < 0.001), higher educational level (p = 0.002), night sleep >7 hours (p = 0.002), and being physically active (p = 0.018) were identified as protective factors. LIMITATIONS: Cross-sectional design and the regional recruitment area limit the generalizability of results. CONCLUSIONS: Mean CPDI values were above the threshold for medium grade peritraumatic distress, with greater CPDI Scores in subjects who tested positive for SARS-CoV-2, compared to family members or caregivers without a clear indication to undergo the swab. Specific demographics, physical and mental health events could help in identifying individuals at greater risk of COVID-19 related peritraumatic distress that may benefit from early treatment.

Supratentorial Embryonal Tumors in the Elderly: Diagnostic Pitfalls and Clinical Prognosis.

Supratentorial embryonal tumors are very rare malignant tumors of neuroectodermal origin, characterized by an aggressive clinical behavior. They occur prevalently in children. They have been sporadically described in adults and represent an even rarer occurrence in elderly patients, raising many issues on the diagnostic pitfalls and their appropriate management. We present an unusual case of embryonal tumor in a 62-year-old man who presented with speech disorder, and partial deficit of the left 3rd and 5th cranial nerves secondary to a left temporo-insular embryonal tumor: the clinico-radiological features, histopathological insights, therapeutic options and results are discussed along with a review of the most relevant literature, addressing the specific issue of differential diagnosis and the expected results in the elderly population.

Cerebral sinovenous thrombosis (CSVT) in children: what the pediatric radiologists need to know.

Cerebral sinovenous thrombosis (CSVT) is a relatively uncommon and potentially life-threatening condition in childhood, occurring in various clinical settings. Nowadays, however, it is increasingly diagnosed as related to many causes, likely due to greater clinical awareness and improvement of neuroradiologic techniques. The prompt diagnosis is an important goal to significantly reduce the risk of acute complications and long-term sequelae. The purpose of this narrative overview is to provide a useful educational tool in daily clinical practice for radiologists with a broad perspective of CSVT including a discussion of more common potential pitfalls related to misinterpretation of images in children. This paper will also review the normal venous anatomy, its variants, risk factors that contribute to cause CSVT (neonates with their specific causes of CSVT are not included in this review) and the practical imaging feature of cerebral sinovenous thrombosis on MRI and CT. Finally, a brief overview of frequent and severe CSVT conditions in children with key points in imaging is shown.

Paraganglioma of the cauda equina region.

BACKGROUND CONTEXT: Cauda equina paragangliomas (CEPs) are rare neuroendocrine tumors. The difficulty in differential diagnosis with other tumors of this region may be misleading for surgical planning and prognostic expectations. PURPOSE: To report on a rare case of CEP and review the most current information regarding the diagnosis, treatment options, and outcomes. STUDY DESIGN: Case report and literature review. PATIENT SAMPLE: One patient affected by CEP. METHODS: We report on a 33-year-old woman with a 2-month history of worsening low back pain, aggravated by sitting, bending, and coughing. Neurological examination revealed normal power and muscular tone, no sensory or sphincter abnormality, and normal reflex. Magnetic resonance imaging of the lumbar spine demonstrated an intradural extramedullary lesion at L3, with homogeneous contrast enhancement and hypointense punctate foci. The patient underwent an L3 laminectomy and tumor removal. Relevant articles covering CEPs from 1970 to the present were reviewed. RESULTS: The histopathological examinations described paraganglioma features. The postoperative course was uneventful, and all the symptoms resolved, with no tumor recurrence after 3 years' follow-up. CONCLUSIONS: Cauda equina paragangliomas are rare, benign, and slow-growing tumors. Except for its secreting tumor characteristics, preoperative CEP diagnosis is very difficult. Magnetic resonance imaging is important and may suggest specific radiological features for these tumors; however, these are only relative, and it is rare that diagnosis is made before surgery. Diagnosis is established by histological examination and electron microscopy, and immunohistochemical techniques must be used to achieve a correct diagnosis. Cauda equina paragangliomas are well-encapsulated tumors that may be cured by surgery alone, whereas radiotherapy is reserved for incompletely resected tumors. Overall, prolonged postoperative observation is mandatory because of the slow tumor evolution and the possibility of tumor relapse even up to 30 years after surgery.
