Maxillo-mandibular osteoradionecrosis following C-ion radiotherapy: Clinical notes and review of literature

Osteoradionecrosis (ORN) is one of the most feared complications after head and neck radiotherapy. Among head and neck sites, the mandible is the most commonly involved bone. Heavy ion radiotherapy delivers high-dose distribution focused to the target while simultaneously sparing of the adjacent organs but there are anyway some reported cases of ORN. Cases in literature reported well-known risk factors for its developing (e.g. tobacco and alcohol abuse, diabetes), but other are still debated (e.g. teeth extraction during radiotherapy). Prevention is mandatory but multimodal care may be required, tailoring all treatments on the patient needs. This study, after a brief revision of the literature, reports and a case of maxillo-mandibular ORN following carbon-ion (C-ion) radiotherapy and its treatment

ENT Referral From Emergency Department During COVID-19: A Single-Center Experience.

Purpose: COVID-19 pandemic transformed the health system response worldwide. The aim of this study is to report changes about numbers and reason for ENT consultations in emergency department (ED) during COVID-19 pandemic comparing with those occurred the previous year (2019). Methods: Data about patients admitted to adult and pediatric ED were collected from March 1 to May 31, 2019 and 2020. Patients referred for urgency from general practitioners were excluded from the study. Results: Global ED admission (except for dyspnea or COVID-19–related symptoms) dramatically decreased during pandemic (−50.9% among adults and −71.4% among pediatrics). At the same time, ENT consultancy significantly reduced too, by 71.5% ( P < .01) among adults and 45.1% ( P < .01) for pediatrics. Among adults, it was reported a statistically significant decrease in consultation for ear problems (−88.5%, P = .0146). Reduction in ENT referral for bone fracture (−40%, P = .059), vertigo (−77.8%, P = .637), and tonsillitis (−87.5%, P = .688) was consistent, but not significant. Among pediatric patients, it was observed an increase by 25% about foreign bodies (12 vs 15, P < .01). A reduction in numbers of consults for ear problem (−90.8%; P = .045), epistaxis (−80%; P = .196), and nasal fracture (−70%; P = .36) was also observed. Conclusion: Fear of infection and the forced lock down caused a significant decrease in the number of ED accesses and in ENT consultancy. These data may suggest that some ED referral usually could be deferred, but on the other hand, pandemic will cause a great diagnostic delay

In Vitro Selection of Lactobacillus and Bifidobacterium Probiotic Strains for the Management of Oral Pathobiont Infections Associated to Systemic Diseases

: The human oral pathobionts Aggregatibacter actinomycetemcomitans, Streptococcus mitis and Streptococcus mutans, in dysbiosis-promoting conditions, lead to oral infections, which also represent a threat to human systemic health. This scenario may be worsened by antibiotic misuse, which favours multi-drug resistance, making the research on pathogen containment strategies more than crucial. Therefore, we aimed to in vitro select the most promising probiotic strains against oral pathogen growth, viability, biofilm formation, and co-aggregation capacity, employing both the viable probiotics and their cell-free supernatants (CFSs). Interestingly, we also assessed probiotic efficacy against the three-pathogen co-culture, mimicking an environment similar to that in vivo. Overall, the results showed that Lactobacillus CFSs performed better than the Bifidobacterium, highlighting Limosilactobacillus reuteri LRE11, Lacticaseibacillus rhamnosus LR04, Lacticaseibacillus casei LC04, and Limosilactobacillus fermentum LF26 as the most effective strains, opening the chance to deeper investigation of their action and CFS composition. Altogether, the methodologies presented in this study can be used for probiotic efficacy screenings, in order to better focus the research on a viable probiotic, or on its postbiotics, suitable in case of infections

Dupilumab in the treatment of severe uncontrolled chronic rhinosinusitis with nasal polyps (CRSwNP): A multicentric observational Phase IV real-life study (DUPIREAL)

Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is associated with significant morbidity and reduced health-related quality of life. Findings from clinical trials have demonstrated the effectiveness of dupilumab in CRSwNP, although real-world evidence is still limited. Methods This Phase IV real-life, observational, multicenter study assessed the effectiveness and safety of dupilumab in patients with severe uncontrolled CRSwNP (n = 648) over the first year of treatment. We collected data at baseline and after 1, 3, 6, 9, and 12 months of follow-up. We focused on nasal polyps score (NPS), symptoms, and olfactory function. We stratified outcomes by comorbidities, previous surgery, and adherence to intranasal corticosteroids, and examined the success rates based on current guidelines, as well as potential predictors of response at each timepoint. Results We observed a significant decrease in NPS from a median value of 6 (IQR 5–6) at baseline to 1.0 (IQR 0.0–2.0) at 12 months (p &lt; .001), and a significant decrease in Sino-Nasal Outcomes Test-22 (SNOT-22) from a median score of 58 (IQR 49–70) at baseline to 11 (IQR 6–21; p &lt; .001) at 12 months. Sniffin' Sticks scores showed a significant increase over 12 months (p &lt; .001) compared to baseline. The results were unaffected by concomitant diseases, number of previous surgeries, and adherence to topical steroids, except for minor differences in rapidity of action. An excellent-moderate response was observed in 96.9% of patients at 12 months based on EPOS 2020 criteria. Conclusions Our findings from this large-scale real-life study support the effectiveness of dupilumab as an add-on therapy in patients with severe uncontrolled CRSwNP in reducing polyp size and improving the quality of life, severity of symptoms, nasal congestion, and smell

Fatality rate and predictors of mortality in an Italian cohort of hospitalized COVID-19 patients

Clinical features and natural history of coronavirus disease 2019 (COVID-19) differ widely among different countries and during different phases of the pandemia. Here, we aimed to evaluate the case fatality rate (CFR) and to identify predictors of mortality in a cohort of COVID-19 patients admitted to three hospitals of Northern Italy between March 1 and April 28, 2020. All these patients had a confirmed diagnosis of SARS-CoV-2 infection by molecular methods. During the study period 504/1697 patients died; thus, overall CFR was 29.7%. We looked for predictors of mortality in a subgroup of 486 patients (239 males, 59%; median age 71 years) for whom sufficient clinical data were available at data cut-off. Among the demographic and clinical variables considered, age, a diagnosis of cancer, obesity and current smoking independently predicted mortality. When laboratory data were added to the model in a further subgroup of patients, age, the diagnosis of cancer, and the baseline PaO2/FiO2 ratio were identified as independent predictors of mortality. In conclusion, the CFR of hospitalized patients in Northern Italy during the ascending phase of the COVID-19 pandemic approached 30%. The identification of mortality predictors might contribute to better stratification of individual patient risk

Does Prolonged FFP2 Mask Use Cause Changes in Nasal Cytology? A Pilot Observational Study on Healthcare Workers

TheCOVID-19 pandemic has rapidly spread worldwide. Individual prevention approaches include FFP2/N95 mask use. Healthcare (HC) workers wear face masks for a long time during their work shifts and often complain of nasal symptoms. Current data on mask-associated symptoms or upper airway epithelium transformations are limited. Nasal cytology (NC) is a useful, non-invasive diagnostic method to assess cellular alterations. The aim of this study is to compare NC in HC workers before and after the continuous wearing of FFP2 face masks. We conducted a pilot observational study on 10 volunteer HC workers, who continuously used FFP2 masks during the work shift. All subjects underwent NC at the beginning (T0) and at the end of their workshift (T1) and the cytological findings were compared. Moreover, nasal symptoms were collected. Rare inflammatory cells were detected at T0 and, comparing cytological data about T0 and T1, no significant differences were observed. The most reported nasal symptoms were itching (70%) and a dry nose (60%). Difficulty of breathing and nasal blockage were not relevant. These preliminary data seem to suggest that wearing an FFP2 mask does not determine observable alterations in NC in daily work. However, further studies on a larger population for a longer period are needed

Gastric Cancer with Positive Peritoneal Cytology: Survival Benefit after Induction Chemotherapy and Conversion to Negative Peritoneal Cytology

Background The optimal treatment in patients with gastric cancer and peritoneal disease remains controversial. Some guidelines indicate palliative treatment only, while others consider surgical treatment in case of positive lavage cytology (CY+) or limited peritoneal disease. Here, we analyzed the role of peritoneal disease in patients with gastric cancer, and the prognostic relevance of response to neoadjuvant therapy. Methods In this retrospective cohort analysis, we analyzed patients with adenocarcinoma of the stomach or esophago-gastric junction from a single center operated between 2011 and 2019. According to histology and lavage cytology, patients were classified into four risk groups: (A) no peritoneal disease, (B) CY+ who converted to negative lavage cytology (CY−) after neoadjuvant chemotherapy, (C) CY+ without conversion after chemotherapy, and (D) patients with visible peritoneal metastasis. Results Overall, n = 172 patients were included. At initial presentation, n = 125 (73%) had no peritoneal disease, and about a third of patients (n = 47, 27%) had microscopic or macroscopic peritoneal disease. Among them, n = 14 (8%) were CY+ without visible peritoneal metastasis, n = 9 converted to CY− after chemotherapy, and in n = 5 no conversion was observed. Median overall survival was not reached in patients who had initially no peritoneal disease and in patients who converted after chemotherapy, resulting in 3-year survival rates of 65% and 53%. In contrast, median overall survival was reduced to 13 months (95% CI 8.7–16.7) in patients without conversion and was 16 months (95% CI 12–20.5) in patients with peritoneal metastasis without difference between the two groups (p = .364). The conversion rate from CY+ to CY− was significantly higher after neoadjuvant treatment with FLOT (5-fluorouracil plus leucovorin, oxaliplatin, and docetaxel) compared to ECF (epirubicin, cisplatin, and 5-fluorouracil) (p = 0.027). Conclusion Conversion of CY+ to CY− after neoadjuvant chemotherapy with FLOT is a significant prognostic factor for a better overall survival. Surgical treatment in well-selected patients should therefore be considered. However, peritoneal recurrence remains frequent despite conversion, urging for a better local control

Voice quality after treatment for T1a glottic carcinoma--radiotherapy versus laser cordectomy

The purpose of this study was to assess the anatomic and functional outcomes and compare the voice quality in patients affected by T1a glottic carcinoma treated with curative intent with radiotherapy or laser cordectomy. Fifty-seven cases were analysed: 27 after curative radiotherapy and 30 after laser cordectomy. All patients were studied with videolaryngostroboscopy, voice analysis by narrow spectrogram, and vocal parameters (Jitter, Shimmer, noise/harmonic ratio, and diplophonia). Videolaryngostroboscopy showed severe glottic inadequacy in 25% of cases treated with radiation and insufficient compensation \u2018ventricular band\u2019 or \u2018with arytenoid hyperadduction\u2019 in 65% of cases after surgery. Severe dysphonia on the electro-acoustic analysis of voice was observed in 25% of cases after radiation and 70% after laser (pB/0.001). Fundamental frequency and vocal parameters showed more favourable results in the radiation group (pB/0.001). Voice assessment showed better results after radiotherapy compared with laser cordectomy. Voice outcome should be carefully considered in the treatment decision for T1 glottic carcinoma
