“…Notably, there was no winter-spring peak from late 2020 to early 2021. This was the first time in over a decade, as reported by LIU's study on influenza monitoring in Huzhou City from 2011 to 2017 [22], that a winter-spring flu season did not occur. This further demonstrates the effectiveness of Huzhou's COVID-19 control measures.…”

Purpose To assess the epidemiology of seasonal influenza in Huzhou City, Zhejiang Province, China, during 2018–2022 and provide insights for influenza prevention. Methods Following the National Influenza Surveillance Program, we conducted pathogen surveillance by randomly sampling throat swabs from cases with influenza-like illness (ILI) at two sentinel hospitals. Results From 2018 to 2022, a total of 3,813,471 cases were treated at two hospitals in Huzhou, China. Among them, there were 112,385 cases of Influenza-Like Illness (ILI), accounting for 2.95% of the total number of cases. A total of 11,686 ILI throat swab samples were tested for influenza viruses, with 1,602 cases testing positive for influenza virus nucleic acid, resulting in a positivity rate of 13.71%. Among the positive strains, there were 677 strains of A(H3N2) virus, 301 strains of A(H1N1) virus, 570 strains of B/Victoria virus, and 54 strains of B/Yamagata virus. The ILI percentage (ILI%) and influenza nucleic acid positivity rate showed winter-spring peaks in the years 2018, 2019, 2021, and 2022, with the peaks concentrated in January and February. Additionally, a small peak was observed in August 2022 during the summer season. No peak was observed during the winter-spring season of 2020. The highest proportion of ILI cases was observed in children aged 0–4 years, followed by school-age children aged 5–14 years. There was a positive correlation between ILI% and influenza virus nucleic acid positivity rate (r = 0.60, p < 0.05). Conclusions The influenza outbreak in Huzhou from 2020 to 2022 was to some extent influenced by the COVID-19 pandemic and public health measures. After the conclusion of the COVID-19 pandemic, the influenza outbreak in Huzhou may become more severe. Therefore, it is crucial to promptly assess the influenza outbreak trends based on the ILI% and the positivity rate of influenza virus nucleic acid tests.

“…There is a male predominance and the most common age group is the elderly with age >60. The International Prognostic Index (IPI) is the most commonly used staging system for DLBCL [4][5][6]. The standard of care is chemotherapy with R-CHOP.…”

“…However, patients can also present with multiple different cranial neuropathies, including diplopia, dysphagia, and local mass effect symptoms, including proptosis. Of the sinuses, the most common location is the maxillary followed by the ethmoid, sphenoid, and frontal sinus [5]. Since the presentation of such a mass is uncommon, diagnosis is often delayed until more prominent features develop from the mass effect such as proptosis, eye swelling, and blurred vision.…”

Primary Sinonasal Lymphoma: A Rare Cause of Cranial Neuropathies

Primary sinonasal lymphomas are a rare type of non-Hodgkin lymphoma (NHL) with an overall incidence of about 1% of all head and neck cancers. Diffuse large B-cell lymphoma (DLBCL) is the most common type of NHL and it most commonly occurs in elderly men. The diagnosis of such a lymphoma is difficult because of its varied presentation, which usually occurs late after a significant mass effect has taken place. Symptoms vary significantly, from simply nasal obstruction or epistaxis to varied cranial neuropathies or the confusion seen with central nervous system (CNS) spread. Patients may present with a large orbital mass and proptosis. Therefore, emphasis should be placed on earlier detection by using appropriate imaging modalities to reveal such masses. A biopsy is necessary to confirm the diagnosis. The prognosis is scored by the International Prognostic Index. Staging scans with whole-body computed tomography (CT) with contrast and positron emission tomography-fluorodeoxyglucose (PET-FDG) are required to determine other areas of involvement. Treatment is with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) with the casedependent use of intrathecal chemoprophylaxis (methotrexate) to prevent CNS spread. Here, we present a case series of two patients who were found to have a primary sinonasal lymphoma of the DLBCL type. In both cases, the presenting symptoms were vague. A high index of suspicion is required to diagnose NHL early on, which portends the best chance of a successful outcome. This article seeks to emphasize the role of including primary sinonasal lymphoma as a differential in the presentation of unrelenting cranial neuropathies or facial mass.

“…In a case report of a 58-year-old female patient with right maxillary sinus lymphoma, the patient had CNS relapse with a left pontine lesion that was removed and found to be consistent with DLBL. A few days later, she suffered from right limb weakness and was found to have cervical spinal cord metastasis [4-5].…”

Paranasal sinus lymphoma (PNL) is a rare presentation of extranodal non-Hodgkin lymphoma (NHL) with a natural history different from other types of lymphoma. The maxillary sinus is the most common paranasal sinus involved in NHL. Involvement of the central nervous system (CNS) is a rare complication of PNL. In this case report, we present a case of diffuse large B cell lymphoma (DLBL) that developed in the left maxillary sinus and relapsed as a left frontal brain mass after four years of disease remission.
