PRAME Expression in Mucosal Melanoma of the Head and Neck Region

PRAME (PReferentially expressed Antigen in MElanoma), a cancer-testis antigen expressed in normal and neoplastic tissues with several functions, proved to be a useful diagnostic tool in the differential diagnosis between benign and malignant melanocytic lesions. The current study aims to perform PRAME stain on a retrospective case series of mucosal melanocytic tumors of the head and neck region to compare 3 different scores and evaluate the most reliable one in this diagnostic set. Immunohistochemical analysis for PRAME was performed in 54 benign and malignant mucosal melanocytic tumors of the head and neck region collected from 41 patients. The best-performing cutoff of PRAME-positive cells (nuclear stain) to differentiate benign and malignant mucosal melanocytic tumors of the head and neck region is that proposed by Raghavan and colleagues (<60%/≥60% of PRAME-positive cells), with 100% and 77.8% of benign lesions and malignant tumors respectively correctly identified. Applying this score, PRAME stain showed the best results (sensitivity, specificity, accuracy, and positive and negative predictive values) for the diagnosis of head and neck melanocytic tumors. However, a subset of PRAME-negative malignant tumors was identified, especially located in the palatal area (hard and soft palate). Finally, high PRAME expression (≥60%) was associated with specific sites (nasal cavity/nasal septum/turbinates nasopharynx, and the maxillary sinus), nodular histotype, and female sex

Pelvic trauma : WSES classification and guidelines

Complex pelvic injuries are among the most dangerous and deadly trauma related lesions. Different classification systems exist, some are based on the mechanism of injury, some on anatomic patterns and some are focusing on the resulting instability requiring operative fixation. The optimal treatment strategy, however, should keep into consideration the hemodynamic status, the anatomic impairment of pelvic ring function and the associated injuries. The management of pelvic trauma patients aims definitively to restore the homeostasis and the normal physiopathology associated to the mechanical stability of the pelvic ring. Thus the management of pelvic trauma must be multidisciplinary and should be ultimately based on the physiology of the patient and the anatomy of the injury. This paper presents the World Society of Emergency Surgery (WSES) classification of pelvic trauma and the management Guidelines.Peer reviewe

Correlation between chronic rhinosinusitis with nasal polyposis (CRSwNP) severity and asthma control

Background: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is a predominantly type 2-mediated inflammatory disease with high social and economic burdens. According to the "unified airway diseases theory", CRSwNP and asthma often occur simultaneously as comorbidities, complicating their overall management. Objective: We aimed to evaluate the correlation between CRSwNP severity, according to the Clinical-Cytological Grading (CCG), and asthma control.Methods: 151 patients suffering from both CRSwNP and asthma step Gina 4-5 were recruited. We examined patients' clinical history and administered to each patient the Asthma Control Test (ACT). Moreover, we performed nasal endoscopy and nasal cytology on all patients. According to nasal cytology findings and comorbidities each patient was assigned a CCG score. Kolmogorov-Smirnov and Shapiro-Wilk tests were performed. A ROC curve was constructed to detect the accuracy of the CCG in detecting not well controlled asthma.Results: The mean ACT was 18.44 +/- 4.53. 57 % of patients suffered from not well controlled or poorly controlled asthma. The mean CCG score was 6.68 +/- 2.01. 54.3 % of patients had a severe CCG value. Well-controlled asthmatic patients had a lower percentage of severe CCG and a higher percentage of mild CCG. 50 % of patients with non-well or poorly controlled asthma showed a mixed eosinophil-mast cell infiltrate. A CCG <6 and the absence of the simultaneous presence of eosinophils and mast cells in the nasal cytology were associated with well-controlled asthma.Conclusions: Patients with high-grade CCG, especially with mixed eosinophil-mast cell inflammatory infiltrate at nasal cytology, are more prone to uncontrolled asthma

Chronic rhinosinusitis with nasal polyps: how to identify eligible patients for biologics in clinical practice

Obiettivo. Questo studio confrontava 3 differenti indici di gravità della rinosinusite cronica con poliposi nasale (RSCcPN). L’obbiettivo era individuare i pazienti eleggibili al trattamento con farmaci biologici. Metodi. 330 pazienti adulti con RSCcPN erano arruolati. Tutti i pazienti venivano valutati mediante nasal polyp score (NPS), sinonasal outcome test (SNOT-22) e clinical-cytological grading (CCG). Inoltre erano considerati la storia clinica, i pregressi interventi chirurgici ed il controllo dell’asma. Risultati. Solamente 45 (13,6%) pazienti avevano i 3 indici positivi. La concordanza tra i 3 indici era bassa/modesta. I pazienti con la malattia grave (contestuale positività a tutti i test) avevano peggiori parametri. Il citotipo misto (OR = 4,07), l’ostruzione nasale (OR = 10,06), il post-nasal drip (OR = 1,98), il disagio (OR = 2,53), e la difficoltà ad addormentarsi (OR = 1,92) erano significativamente associati con la malattia grave. Conclusioni. È preferibile utilizzare contemporaneamente i 3 test per individuare i pazienti candidati alla terapia biologica. In questo modo si può avere un quadro generale della malattia, comprendente la morfologia dei polipi, lo stato di infiammazione, le comorbidità, i sintomi e la qualità della vita.Objective. This study compared three severity measures for chronic rhinosinusitis with nasal polyps (CRSwNP). The outcome was to identify patients who are eligible for biological therapy. Methods. 330 adult patients with CRSwNP were examined. Nasal polyp score (NPS), sinonasal outcome test (SNOT-22) and clinical-cytological grading (CCG) were compared. Clinical history, past surgery and asthma control test were also considered. Results. Only 45 (13.6%) patients had a contextual positivity to the three severity measures. The concordance among tests was slight/fair. Patients with severe disease (all tests positive) had more impaired parameters. The mixed cytotype (OR = 4.07), nasal obstruction (OR = 10.06), post-nasal drip (OR = 1.98), embarrassment (OR = 2.53) and difficulty falling asleep (OR = 1.92) were significantly associated with severe CRSwNP. Conclusions. To identify candidates for biological therapy, the contextual use of NPS, SNOT-22 and CCG is preferable. In this way, global assessment of CRSwNP, including morphology, inflammation, comorbidity, symptoms and quality of life is possible
