ABSTRACT
Background: During Covid-19 pandemic, the massive use of Personal Protective Equipment could provoke severe adverse reactions in latex allergy patients and could negatively affect their quality of life. Method(s): The observational single-centre present study was carried out on 67 adult subjects with a latex allergy diagnosis followed by Allergy Unit of Fondazione Policlinico Universitario A. Gemelli IRCCS of Rome. All data were collected from January 2020 to December 2020. All patients underwent to a survey focused on their clinical and psychological conditions during Covid-19 pandemic. For the evaluation of the degree of well-being, we used SF-36 questionnaire (Short-Form 36-Item Health Survey). The aim of our study is: (a) to evaluate the incidence of allergic reactions in patients with latex allergy during the SARS-CoV- 2 pandemic;(b) to evaluate the protective role of continuous latex ITS during this period;(c) to evaluate quality of life of natural rubber latex allergy (NRLA) patients during the pandemic. Result(s): 67 patients (9 males and 58 females, mean age of 45.9 +/- 11.4 years) suffered from latex allergy were included in the present study. We recorded among our patients 13 cases (34.2%) of urticarial/ angioedema (U/A), 9 cases (23.6%) of respiratory symptoms (RS;dyspnoea, shortness of breath, wheezing) and 7 cases (18.4%) of anaphylaxis. In patients undergone continuous ITS, we observed less cases of U/A (p < 0.001), RS (p < 0.001), anaphylaxis (p = 0.003), hospitalizations (p = 0.014) and a lower therapy administration. We compared the results of SF-36 questionnaire in patients undergone continuous and not continuous latex ITS with a significance differences score between these two groups. Conclusion(s): The pandemic challenged the capacity of healthcare systems to provide adequate management of NRLA patients and in this context, we performed a survey to monitor their health status. During the pandemic, the risk of latex exposure was significant increased considering the possibility of direct skin contact, airborne exposure, contamination of food and medical evaluations. Our study is the first that investigated the clinical and quality of life effects of Covid-19 pandemia in NRLA patients demonstrating the importance of SLIT adherence also in this complex period.

ABSTRACT
Summary: Background. International guidelines suggested skin tests with Polyethylene-glycol (PEG) and polysorbate 80 (PS-80), to investigate a possible hypersensitivity to these excipients either to identify subjects at risk of developing allergic reactions to Covid-19 vaccines, or in patients with suspected IgE mediated hypersensitivity reactions (HR) to the Covid-19 vaccine. The main purpose of this study was to investigate the prevalence of PEG and PS sensitization in patients with a clinical history of HR to drugs containing PEG/PS and in patients with a suspected Covid-19 vaccine immediate HR. Methods. This was a multicenter retrospective study conducted by allergists belonging to 20 Italian medical centers. Skin testing was performed in 531 patients with either a clinical history of suspected hypersensitivity reaction (HR) to drugs containing PEG and/or PS-80 (group 1:362 patient) or a suspected HR to Covid-19 vaccines (group 2: 169 patient), as suggested by the AAIITO/SIAAIC guidelines for the "management of patients at risk of allergic reactions to Covid-19 vaccines" [1]. Results. 10/362 (0.02%) had positive skin test to one or both excipients in group 1, 12/169 (7.1%) in group 2 (p less than 0.01). In group 2 HRs to Covid-19 vaccines were immediate in 10/12 of cases and anaphylaxis occurred in 4/12 of patients. Conclusions. The positivity of skin test with PEG and or PS before vaccination is extremely rare and mostly replaceable by an accurate clinical history. Sensitization to PEG and PS has to be investigated in patients with a previous immediate HR to a Covid-19 vaccine, in particular in patients with anaphylaxis.
ABSTRACT
INTRODUCTION: Squamous carcinoma is a very rare breast cancer resulting from a differentiated squamous metaplasia. Its diagnosis is late due to the absence of specific clinical and radiological features. PRESENTATION OF CASE: The authors present the case of a 39-year-old patient with the clinical onset of an inflammatory cyst diagnosed with mammography and cytological examination. After segmentectomy, on histological examination was defined as: "squamous keratinizing aspect". In light of this report she was subjected to quadrantectomy with lymphadenectomy. She did not undergo radiotherapy treatment, which was delayed due to the ongoing pandemic. After a few months developed a local recurrence and underwent a mastectomy with multidisciplinary treatment. DISCUSSION: Squamously-differentiated metaplastic carcinoma of the breast is one of the rarest forms of breast cancer. Its etiopathogenesis is still unclear but some authors suggest that it originates from a squamous metaplasia deriving from the epithelium of cysts. This is a very aggressive and fast-growing tumour especially in young women, in fact the patient had a recurrence after a few months. She came to our attention 6 months after the initial surgery with a relapse at a local-regional level for which she was subjected to radical treatment and with a metastatic spread for which she was given the first-line chemotherapy treatment. CONCLUSION: There are no well-defined guidelines for the treatment of this rare form of cancer. The case illustrates how the rapid aggressiveness of the disease requires adequate and immediate multidisciplinary treatment from the very beginning.
ABSTRACT
In Diabetes Mellitus the loss of capacity to regulate immunity, the reduction of pulmonary functions and the pro-thrombotic state determine the severity of COVID-19.
