Background: The aim of this study was to identify potential variables influencing the clinical presentation of breakthrough cancer pain (BTP). Methods: Cancer patients with a diagnosis of BTP were enrolled. Demographic and clinical characteristics, as well as background pain and BTP characteristics were collected. Multivariate analyses were conducted to assess the correlation between BTP characteristics and the variables examined. Results: Data of 4016 patients were analysed. Average daily number of BTP episodes was 2.4, mean intensity was 7.5, and a mean duration was 43.3 min. A short onset BTP was observed in 68.9% of patients. In 30.5% of patients BTP was predictable. There were 86.0% of participants who reported a marked interference of BTP with their daily activities. Furthermore, 86.8% of patients were receiving opioids for the management of BTP. The average time to meaningful pain relief was 16.5 min and 70.9% of patients were satisfied with their BTP medications. Age, head and neck cancer, Karnofsky, background pain intensity, predictable and fast onset BTP were independently associated with the number of BTP episodes. BTP pain intensity was independently associated with background pain intensity, fast onset BTP, and Karnofsky. Neuropathic pain mechanism was independently associated with unpredictable BTP. Variables independently associated with a longer duration of BTP were age, place of visit, cancer diagnosis, disease-oriented therapy, background pain intensity and mechanism, and unpredictable BTP. Age, Karnofsky, background pain intensity, fast onset, and long duration of BTP were independently associated with interference with daily activity. Conclusions: BTP has a variable presentation depending on interdependent relationships among its different characteristics.

This survey performed by an Italian observatory expert review group, has confirmed that the BTP represents a clinically relevant condition with a negative impact on the patient's quality of life. BTP was detected in all settings involved. A number of factors are associated with the BTP. Also factors regarding the course of disease and setting of care have been assessed. This information may help in stratifying patients or predicting the risk of development of BTP with specific characteristics.

IntroductionAn ongoing national multicenter survey [Italian Oncologic Pain multiSetting Multicentric Survey (IOPS-MS)] is evaluating the characteristics of breakthrough cancer pain (BTP) in different clinical settings. Preliminary data from the first 1500 cancer patients with BTP enrolled in this study are presented here.MethodsThirty-two clinical centers are involved in the survey. A diagnosis of BTP was performed by a standard algorithm. Epidemiological data, Karnofsky index, stage of disease, presence and sites of metastases, ongoing oncologic treatment, and characteristics of background pain and BTP and their treatments were recorded. Background pain and BTP intensity were measured. Patients were also questioned about BTP predictability, BTP onset (≤10 or >10 min), BTP duration, background and BTP medications and their doses, time to meaningful pain relief after BTP medication, and satisfaction with BTP medication. The occurrence of adverse reactions was also assessed, as well as mucosal toxicity.ResultsBackground pain was well controlled with opioid treatment (numerical rating scale 3.0 ± 1.1). Patients reported 2.5 ± 1.6 BTP episodes/day with a mean intensity of 7.5 ± 1.4 and duration of 43 ± 40 min; 977 patients (65.1%) reported non-predictable BTP, and 1076 patients (71.7%) reported a rapid onset of BTP (≤10 min). Higher patient satisfaction was reported by patients treated with fast onset opioids.ConclusionsThese preliminary data underline that the standard algorithm used is a valid tool for a proper diagnosis of BTP in cancer patients. Moreover, rapid relief of pain is crucial for patients’ satisfaction. The final IOPS-MS data are necessary to understand relationships between BTP characteristics and other clinical variables in oncologic patients.FundingMolteni Farmaceutici, Italy.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a disease known from a few months, caused by a recently arisen virus and, consequently, it is little known. The disease has a benign course in most infected subjects (children and young adults), is often symptomatic in adults over the age of 50 and often serious and life threatening in people with comorbidities and the elderly. The few data published on coronavirus disease-2019 (COVID-19) in the blood-oncology field report a serious clinical presentation, a serious course of the disease, and a high mortality rate, as has also been reported for other cancer contexts. The current strategy for treating patients with SARS-CoV-2 includes antivirals that are effective against other viral infections and drugs that can moderate the cytokine storm. There is no specific vaccine and consequently all possible precautions must be taken to prevent SARS-CoV-2 infection in the areas of oncology, oncohematology, and bone marrow transplantation. In this reviewer's article, we report the information currently available on SARS-CoV-2 infection to help young doctors and hematologists to successfully manage patients with COVID-19.

Background: Cutaneous manifestation of COVID 19 in children has not yet been reviewed systematically and hence this review gives a future direction to the clinicians to be vigilant for skin presentations during such pandemic. Methodology: The review was done as per the guidelines of PRISMA and literature search was done on PubMed database using keywords as COVID-19, children and skin in different combinations. Articles published in English with cases of age 1 month to 18 years were eligible. The outcome included varied aspects of cutaneous and COVID-19 infection. The review protocol was not registered. Results: Of 51 publications identi ed, 13 studies containing 149 children met the eligibility criteria. Acrally located erythematous maculopapular lesion was the most common nding in 138 children. Erythema multiforme, varicella like exanthem and Kawasaki disease like presentations were reported in the rest of the cases. The duration of the skin lesion was 1-2 weeks in 43%. Skin biopsy done in 18 cases revealed super cial & deep perivascular and peri-eccrine lymphocytic in ltrate & lymphocytic vasculitis. RT-PCR was positive in 13.8% cases. Serological markers for HSV, parvovirus B19 analyzed across various studies, were found negative, except for mycoplasma pneumoniae in 2 of 20 cases tested. Discussion: Clinicopathologic analysis established chilblains like lesion in 43% cases with no con rmed etiology like cold exposure, autoimmune dysfunction, drug reaction, or viral infection. The usual cephalocaudal spread of a viral exanthem was also missing. However, a low number of discussed cases was a limitation of the study. Conclusion: In the absence of any con rmed etiology for such cutaneous manifestations, the possibility of COVID-19 should be explored and evaluated thoroughly during such pandemic.

Background: A variety of skin manifestations have been associated with COVID-19 infection. Acral lesions on hands and feet, closely resembling chilblains, have been reported in association with COVID-19, which are nonspecific. These acro-ischemic painful lesions have been described mainly in asymptomatic and mildly symptomatic pediatric COVID-19 positive patients, without a precise pathogenetic mechanism.COVID-19-induced chilblains may portend an indolent course and a good outcome. In young patients, the IFN-1 response induces microangiopathic changes and produces a chilblain lupus erythematosus-like eruption with vasculitic neuropathic pain features. Objectives: This paper presented a case series of pediatric patients with COVID-19-related skin lesions and neuropathic-like pain. Methods: Clinical outcomes were collected from 11 patients diagnosed with painful erythematous skin lesions with neuropathic-like pain and positive IgG for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Results: It is a mildly symptomatic condition not related to severe pain rates, and it is treated with paracetamol due to the transitory nature of the problem, which provides good results. Conclusions: A particular point of interest is skin lesion manifestation as a further indirect sign of SARS-CoV-2 infection. Due to the initial manifestation of chilblains in pauci-symptomatic pediatric patients, they need to be immediately tested and isolated. Chilblains can be considered a clinical clue to suspect SARS-CoV-2 infection and help in early diagnosis, patient triage, and infection control.

AbstractRetroperitoneal fibrosis is a connective disease of the auto-inflammatory/auto-immune type of the retroperitoneum with unknown etiology and pathological mechanism. The manifestations of the pathology can be local or systemic. Amongst the local symptoms, the dull and constant pain in the hips, back or abdomen is the most frequent.We report here a case of a 47-year-old woman, whose pathogenic mechanism could be related to an “IgG4-related disease” disorder as suggested by an increased serum level of this subclass of IgG and the positive immunohistochemistry.The diagnosis is not easy, because this pathology generates masses; adenomegalies with retro peritoneal development, that makes it similar to lymphomas or metastases from ovarian tumors.

AbstractAdministration of rituximab, one of the basic drugs for the therapy of B-cell lymphoproliferative diseases, during pregnancy has been suspected to cause developmental fetal events, particularly if given during the first trimester of pregnancy. Therefore, use in pregnancy is not permitted. Howe ver, several cases of pregnant women being treated with rituximab are reported herein; an exception is often made in cases with grave illness.We describe an exceptional case of a woman with non-Hodgkin lymphoma of the mucosa-associated lymphoid tissue type where rituximab was given as a single agent without interruption during two consecutive pregnancies. This case can certainly supply important indications on the safety of rituximab.
