Chemosensory impairments have been established as a specific indicator of COVID-19. They affect most patients and may persist long past the resolution of respiratory symptoms, representing an unprecedented medical challenge. Since the SARS-CoV-2 pandemic started, we now know much more about smell, taste, and chemesthesis loss associated with COVID-19. However, the temporal dynamics and characteristics of recovery are still unknown. Here, capitalizing on data from the Global Consortium for Chemosensory Research (GCCR) crowdsourced survey, we assessed chemosensory abilities after the resolution of respiratory symptoms in participants diagnosed with COVID-19 during the first wave of the pandemic in Italy. This analysis led to the identification of two patterns of chemosensory recovery, partial and substantial, which were found to be associated with differential age, degrees of chemosensory loss, and regional patterns. Uncovering the self-reported phenomenology of recovery from smell, taste, and chemesthetic disorders is the first, yet essential step, to provide healthcare professionals with the tools to take purposeful and targeted action to address chemosensory disorders and their severe discomfort.

Prolonged human-crewed missions on the Moon are foreseen as a gateway for Mars and asteroid colonisation in the next decades. Health risks related to long-time permanence in space have been partially investigated. Hazards due to airborne biological contaminants represent a relevant problem in space missions. A possible way to perform pathogens’ inactivation is by employing the shortest wavelength range of Solar ultraviolet radiation, the so-called germicidal range. On Earth, it is totally absorbed by the atmosphere and does not reach the surface. In space, such Ultraviolet solar component is present and effective germicidal irradiation for airborne pathogens’ inactivation can be achieved inside habitable outposts through a combination of highly reflective internal coating and optimised geometry of the air ducts. The Solar Ultraviolet Light Collector for Germicidal Irradiation on the Moon is a project whose aim is to collect Ultraviolet solar radiation and use it as a source to disinfect the re-circulating air of the human outposts. The most favourable positions where to place these collectors are over the peaks at the Moon’s poles, which have the peculiarity of being exposed to solar radiation most of the time. On August 2022, NASA communicated to have identified 13 candidate landing regions near the lunar South Pole for Artemis missions. Another advantage of the Moon is its low inclination to the ecliptic, which maintains the Sun’s apparent altitude inside a reduced angular range. For this reason, Ultraviolet solar radiation can be collected through a simplified Sun’s tracking collector or even a static collector and used to disinfect the recycled air. Fluid-dynamic and optical simulations have been performed to support the proposed idea. The expected inactivation rates for some airborne pathogens, either common or found on the International Space Station, are reported and compared with the proposed device efficiency. The results show that it is possible to use Ultraviolet solar radiation directly for air disinfection inside the lunar outposts and deliver a healthy living environment to the astronauts.

Treatment of patients with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH) may affect the quality of sexual function and ejaculation. The effect of new surgical procedures, which are currently available to treat BPH, on erection and ejaculation, has been poorly studied. This study aimed to assess the effect of thulium laser enucleation of the prostate (ThuLEP) on sexual function and retrograde ejaculation in patients with LUTS secondary to BPH. We performed a prospective study in 110 consecutive patients who had undergone ThuLEP to analyze changes in sexual function and urinary symptoms. To evaluate changes in erection and ejaculation, and the effect of urinary symptoms on the quality of life (QoL), five validated questionnaires were used: the ICIQ-MLUTSsex, MSHQ-EjD, International Index of Erectile Function 5, International Prognostic Scoring System (IPSS) questionnaire, and QoL index of the intraclass correlation coefficients. Patients also underwent IPSS and flowmetry to assess the outcome of flow. Patients were evaluated before surgery and 3-6 months after ThuLEP, whereas those with previous abdominal surgery were excluded. The patients' mean age was 67.83 years. Postoperative urinary symptoms improved after surgery. No significant differences in erectile function before and after surgery were observed. As compared with other techniques described in the literature, the percentage of patients with conserved ejaculation increased by 52.7% after ThuLEP. ThuLEP positively affects urinary symptoms and their effect on the QoL of patients as assessed by questionnaire scores. While endoscopic management of BPH (e.g. transurethral resection of the prostate) causes retrograde ejaculation in most patients, those who undergo ThuLEP have conserved ejaculation and erectile function.

Introduction: The purpose of this work was to evaluate the prevalence of the Quinolones resistant Escherichia coli and/or ESBL producers in the population of our catchment area and hospital component. Materials and Methods: From January 2008 to December 2010, all data concerning urine cultures in patients with suspected urinary tract infection and/or asymptomatic bacteriuria referring at our center located in the south of Milan were prospectively evaluated. Results: In 2008, 2136 outpatient and 1232 hospital urine cultures were analyzed. The presence of quinolone-resistant strains was 21% at a local level and 53% in hospitals. ESBL-producing strains were isolated in 3.5% of cases at a local level and 20.5% in hospitals. In 2009, 2396 outpatient and 1320 hospital urine cultures were analyzed. The presence of quinolone-resistant strains was 21% at a local level and 46% in hospitals. ESBL-producing strains were isolated in 5.4% of cases at a local level and 20% in hospitals. In 2010, 2601 outpatient and 1717 hospital urine cultures were analyzed. The presence of quinolone-resistant strains was 34% at a local level and 26% in hospitals. ESBL-producing strains were isolated in 6.7% of cases at a local level and 20.6% in hospitals. The multidrug resistance was significantly (P < 0.01) higher in ESBL-positive strains. Conclusion: Due to rising antibiotic resistance among uropathogens, it is important to have knowledge of the organisms causing urinary tract infections and their antibiotic sensitivity patterns. In areas with high prevalence of E. Coli resistance, performing urine culture before every surgical procedure became mandatory, in order to prevent fatal sepsis.

Purpose Non allergic rhinitis (NAR) comprises different clinical definitions and phenotypes, including non inflammatory non allergic (NINAR) and cellular inflammatory forms. Nasal cytology, usually performed by scraping the inferior turbinate, is a non invasive, cheap and point-of-care tool to distinguish among the different NAR phenotypes, but still a relevant proportion of patients evaluated by nasal cytology receive a non precise definition of NAR phenotype. We hypothesize that collecting nasal cytology samples from middle meatus could increase the diagnostic accuracy. Methods Consecutive patients with chronic rhinitis without evidence of allergic sensitization were assessed for nasal cytology by means of scraping both the inferior turbinate and the middle meatus (lateral-inferior wall of the middle turbinate). Results 107 consecutive patients with NAR were enrolled in the study. According to inferior turbinate cytology, 42.1% were defined as affected by NINAR, 2.8% by bacterial rhinitis, 10.3% by non allergic rhinitis with eosinophils (NARES), 15.0% non allergic rhinitis with neutrophils (NARNE), 19.6% non allergic rhinitis with mast-cells (NARMA) and 10.3% non allergic rhinitis with eosinophils and mast-cells (NARESMA). Middle meatus cytology was in accordance with inferior turbinate cytology in only 37.6% of cases. Eosinophils and mast-cells were detectable more frequently in middle meatus samples (49.5% vs 19.6%, p  < 0.01, 59.8% vs 29.9%, p  < 0.01, respectively). 93.3% of NINAR patients received an inflammatory NAR phenotype at middle meatus cytology: 26.7% NARES, 24.4% NARNE, 31.1% NARMA and 11.1% NARESMA. Conclusion Middle meatus cytology is more reliable than inferior turbinate cytology in phenotyping patients with NAR. Our study strengthen that nasal cytology should be implemented in clinical practice collecting samples at the middle meatus level.

Purpose Loss of smell decreases the quality of life and contributes to the failure in recognizing hazardous substances. Given the relevance of olfaction in daily life, it is important to recognize an undiagnosed olfactory dysfunction to prevent these possible complications. Up to now, the prevalence of smell disorders in Italy is unknown due to a lack of epidemiological studies. Hence, the primary aim of this study was to evaluate the prevalence of olfactory dysfunction in a sample of Italian adults. Methods Six hundred and thirty-three participants (347 woman and 286 men; mean age 44.9 years, SD 17.3, age range 18–86) were recruited from 10 distinct Italian regions. Participants were recruited using a convenience sapling and were divided into six different age groups: 18–29 years ( N  = 157), 30–39 years ( N  = 129), 40–49 years ( N  = 99), 50–59 years ( N  = 106), > 60 years ( N  = 142). Olfactory function, cognitive abilities, cognitive reserve, and depression were assessed, respectively, with: Sniffin’ Sticks 16-item Odor Identification Test, Montreal Cognitive Assessment, Cognitive Reserve Index, and the Beck Depression Inventory. Additionally, socio-demographic data, medical history, and health-related lifestyle information were collected. Results About 27% of participants showed an odor identification score < 12 indicating hyposmia. Multiple regression analysis revealed that OI was significantly correlated with age, sex, and cognitive reserve index, and young women with high cognitive reserve index showing the highest olfactory scores. Conclusion This study provides data on the prevalence of olfactory dysfunction in different Italian regions.

Background: Local and systemic corticosteroids have long been the workhorse in management of chronic rhinosinusitis with nasal polyps (CRSwNP), although there is no universally accepted modality of prescription. We carried out a survey in Italy to capture current trends in the use of topical and systemic corticosteroids in patients with CRSwNP. Methods: A survey was set up on Survey Monkey®. Each author distributed the link to the survey in an ad hoc manner and a total of 437 participants filled out the survey. Results: Mometasone furoate (79.3%) was the most frequently prescribed, administered daily by 61.9% of participants; the remaining preferred to discontinue treatment for brief periods to reduce side effects or to modulate the therapy in mild cases. The majority believe that a short cycle of systemic steroids should be prescribed for re-exacerbation of symptoms and that the number of cycles in the previous year should be evaluated to define control of the disease even if international guidelines do not provide clear indications on this topic. A certain degree of divergence emerged from responses regarding how long and the maximal dose of systemic steroids which place patients at high risk for adverse events. Finally, systemic corticosteroids seem to offer only temporary benefit on recovery of smell without guaranteeing long-term control even if the patient is adherent to topical corticosteroids. Conclusions: Our results highlight the need for clear guidelines on oral steroids, which could help supporting the use of a precision medicine approach, including indications for new biological agents.

PurposeIn 2003, the German Cancer Society (Deutsche Krebsgesellschaft, DKG) launched a certification program aimed at improving the quality of cancer care. The purpose of this article is to describe the experience of the Prostate Cancer Unit (PCU) at Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, in the process towards DKG certification.MethodsIn 2018, PCU decided to apply for certification by adopting DKG catalogue of requirements (CoR) and quality indicators. A multiprofessional working group was established with the aim of acting the necessary steps to meet DKG standards.ResultsOur organizational setting (procedures, personnel) and activities were accurately analyzed, thus outlining strengths and weaknesses, and modified to comply with DKG CoR and indicators. As examples, (1) a quality management plan was developed; (2) measures were taken to strengthen the surgical expertise; (3) cases evaluated in weekly tumor boards were expanded to include surgical cases with pathological risk factors, metastatic, relapsed and castration-resistant patients; (4) a survey was added to the patient-dedicated initiatives already scheduled; (5) the TuDoc software became the tool to register all new cases of prostate cancer patients referred to PCU.ConclusionsThe process of certification requires many efforts but represents a unique opportunity of improving quality of care of prostate cancer patients, making it comparable on an international scale.

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a disease with a significant impact on quality of life. The overall goal of CRSwNP management, as with other chronic conditions, is to achieve “disease control”, and for that reason, a definition of control of disease is pivotal in deciding the best treatment strategy. Although many staging systems have already been developed to evaluate the disease, disease control is not yet to be standardized, and a specific tool that is consistently applied and accepted by all practitioners is still missing in daily clinical practice. To gain an overview of the implementation and limitations of existing guidelines and to shed light on real-life definitions of control and disease severity, we conducted a nationwide survey of otorhinolaryngologists routinely treating CRSwNP to identify unmet clinical needs in Italy. The results showed homogeneous responses regarding the knowledge contained in international guidelines while highlighting the difficulty of their implementation in day-to-day practice. Respondents called attention to the importance of clinical symptoms, giving more weight to the patient’s perspective. Among the symptoms to be considered, respondents emphasized nasal obstruction, followed by loss of sense of smell and rhinorrhea. Others also believe that the physician’s perspective should be considered, and the inclusion of endoscopy as a measure of control was warranted by many. The need for a specific tool that is able to unequivocally ascertain disease control is increasingly pivotal in this new era of biologics for treating CRSwNP.
