The tumor growth was infiltrative. IHC staining revealed positivity for CKpan and squamous cell immunophenotypic markers (CK5/6, p63 and p40), but negativity for myoepithelial markers (SMA, calponin, GFAP and CD10). The EWSR1 gene translocation was detected by FISH. The prognosis was excellent, with the follow-up periods ranging from 8 months to 33 months. During this period, six patients survived without tumor, only one patient with cervical lymph node metastasis. Conclusions CCC of salivary gland is rare and needs to be differentiated from various other types of tumors containing clear cells. Awareness of the histopathologic characteristics, and combined with IHC and molecular genetic examination can avoid misdiagnosis. The biological behavior of the tumor is indolent with a good overall prognosis.Objective To study clinicopathological features and differential diagnosis of IgG4-related diseases (IgG4-RD) in nasal cavity and paranasal sinuses. Methods A retrospective analysis was performed in patients presenting initially with rhinosinusitis or a nasal mass, who also underwent nasal mucosa biopsy in Beijing Tongren Hospital Affiliated to Capital Medical University, from March 2016 to March 2021. According to the latest international classification diagnostic criteria of IgG4-RD published by the American Society of Rheumatology (ACR)/European Association for Rheumatology (EULAR) in 2019, 10 cases of nasal cavity and paranasal sinuses IgG4-RD were diagnosed and included in the study. The clinical features, histopathology and immunohistochemical expression of IgG and IgG4 were analyzed. Results Among the 10 patients, five patients were male and five female. The age ranged from 30 to 71 years (median 52.7 years). Genipin in vivo Nasal polyp/nasal masses were seen in six cases, and lacrimal gland swelling was found in four cases. The serum IgG and IgG4 level was increased in four cases. Microscopically, all 10 cases showed intense lymphoplasmocytic infiltration and varying degrees of fibrosis in nasal or sinus mucosa, while four cases showed occlusive vasculitis. The number of IgG4 positive plasma cells in nasal mucosa was more than 10/high power field (HPF), with a mean of 67/HPF. The number of IgG4 positive plasma cells in the cases with severe fibrosis was significantly lower than in those without. The ratio of IgG4+/IgG+plasma cells was higher than 40% in six cases. Conclusions IgG4-RD in nasal cavity and paranasal sinuses is a local manifestation of a systemic disease, while nasal cavity and paranasal sinuses are rarely involved by IgG4-RD. The diagnosis is based on clinical symptoms, imaging, IgG4-related serology and histopathologic scores. Histopathology has a core diagnostic value. IgG4 serology and imaging have important diagnostic values in the cases without biopsy.

Upper eyelid reconstruction is particularly complex due to its functional and aesthetic importance. We aim to assess the outcomes/ complications of patients who undergo upper eyelid reconstruction of the posterior lamellae with an advancing tarsonconjunctival flap from the same affected eyelid, following excision of a periocular malignancy by Mohs Micrographic Surgery.

A retrospective consecutive case note review of all eight patients who underwent the procedure between May 2016 and Jan 2021 were included. Patient demographics and factors influencing outcomes (smoking status, use of blood thinners, past medical/ drug history, size/location of the defect), follow up duration and complications were recorded.

Minor post-operative complications included an eyelid notch and retraction. There was one patient with lagophthalmos, but no exposure keratopathy. Two patients had misdirected lashes, one requiring electrolysis. Both monocular patients, who required the procedure in their only seeing eye, and were una axis is unacceptable, although the risk of wound dehiscence is high. This technique forms a valuable part of the systematic reconstructive algorithm.

Violence on the job has been shown to harm both physical and psychosocial health, but the results presented in existing studies might be biased because they have not considered prior indicators of such health.

Physical violence and threats were pooled into a measure of workplace violence for 77,388 randomly sampled respondents from the working population in Denmark in 2012, 2014, and 2016. Longitudinal analyses of these survey data merged with administrative records on sick leave (exceeding 30 days, implying that the consequences of the violence were more serious) were performed. Separate analyses were conducted by sector, gender, and by gender within sectors.

Experiencing violence increased sick leave +36% from before to after the violence relative to the general trend among other respondents that did not experience a violent event.

Work-related violence is a serious health issue, especially in health care, even when we meticulously took prior use of sick leave into account to obtain less biased results.

To investigate differences in outcomes between active-fluidics and gravity-fluidics phacoemulsification systems.

We searched PubMed, Embase, and Cochrane Library databases for randomized controlled trials (RCTs) published no later than December 1, 2021. The Cochrane Collaboration risk of bias tool was used for quality assessment. We presented the outcomes as standardized mean differences (SMDs) with 95% confidence intervals (CI). Sensitivity analysis was performed by removing studies that included ≥2 types of phacoemulsification tips.

We analyzed six RCTs that totally enrolled 884 patients. Patients undergoing lens extraction with active-fluidics systems exhibited lower cumulative dissipated energy (CDE), total aspiration time (TAT), and estimated fluid usage (EFU) compared with patients who did not (SMD [95% CI] CDE, - 0.818 [ - 1.054 to - 0.582]; TAT, - 0.664 [ - 0.850 to - 0.479]; EFU, - 0.655 [ - 0.932 to - 0.378]). A sensitivity analysis revealed similar results for CDE, TAT, and EFU. For endothelial cell density (ECD) 1 week after surgery, ECD 1 month after surgery, and central corneal thickness (CCT) 1 week after surgery, outcomes of both systems were comparable (ECD at 1 week, 0.074 [ - 0.177 to 0.325]; ECD at 1 month, 0.069 [ - 0.167 to 0.305]; CCT 1 week after surgery, 0.077 [ - 0.173 to 0.328]). No severe adverse events in patients treated with either system were reported in the studies.

Active-fluidics systems are superior to gravity-fluidics systems with respect to CDE, TAT, and EFU; no differences in postoperative ECD and CCT were observed. Future studies are required to determine the reasons for heterogeneity and to detect rare adverse events.

Noninvasive respiratory support has reduced the need for mechanical ventilation and surfactant administration in very premature neonates. We sought to determine how the increased use of noninvasive ventilation and less surfactant instillation has impacted the development of bronchopulmonary dysplasia (BPD) using four currently used BPD definitions.

This is a retrospective, single-center cohort study of neonates born at less than 28 weeks gestation between 2010 and 2018. A respiratory practice change (less surfactant and more noninvasive ventilation) occurred in 2014 following participation in the Surfactant Positive Airway Pressure and Pulse Oximetry trial. Therefore, patients were divided into two epochs to compare postnatal respiratory and clinical course and BPD outcomes across four currently relevant definitions (Vermont Oxford Network, National Institute of Child Health and Human Development, Canadian, andNeonatal Research Network).

Clinical and demographic variables were similar between epochs. Deng of the risk factors associated with BPD and a consensus definition is urgently needed to 1) more accurately compare various studies, 2) help facilitate the conduct of clinical trials, and 3) enhance the development of novel therapeutic interventions to improve outcome.>Objective To ascertain the prevalence of culturally native Spanish-speaking child neurologists in the United States. Methods Prevalence statistics regarding demographic and work profile were applied to data obtained from a cross-sectional electronic survey of Child Neurology Society (CNS) members. Results Demographics of the 135 respondents were comparable to a similar CNS survey except for ethnicity as shown in Table 1. Fifty- three percent were male and 24% were over age 60. Approximately a quarter were represented each from East, South, Midwest, and Western US. 42% self-identified as Spanish, Hispanic, or Latino. 62% spoke English as their primary language and 39% spoke Spanish as their primary language. Two-thirds graduated from a US medical school, 51% practice general neurology, and epilepsy was the most common subspecialty (18%). Two-thirds of respondents practice at a major teaching hospital, and 93% hold university academic appointments. 79% are AAN members. 76% did not have medical student debt at the time of the survey. 29% report signs consistent with burnout. 87% would choose Child Neurology again and 96% would recommend Child Neurology to a medical student. Conclusion 40% of survey respondents self-identified as Hispanic, Latino or Spanish and spoke Spanish as the primary language and the majority practice in Academic Medicine. Nearly a third of those in the current survey identify burnout symptoms. Consideration of distinctive language and cultural characteristics across the US may lead to provision of a more patient-centered and equitable care.

The identification of immunoglobulin G antibodies against the aquaporin-4 channel (AQP-IgG) in the majority of adult patients differentiates neuromyelitis optica as a distinct disease entity. The high specificity of AQP4-IgG for neuromyelitis optica has allowed the identification of seropositive patients with atypical presentations of this disease. Neuromyelitis optica spectrum disorder has been increasingly recognized in children who demonstrate patterns of clinical involvement beyond the traditional boundaries of the optic pathways and spinal cord.

This is a single-center, retrospective review comparing demographic, clinical/paraclinical, and laboratory features of children and adults with a serologically confirmed diagnosis of AQP4-IgG-positive neuromyelitis optica spectrum disorder.

Of 151 reviewed patient charts, 12 pediatric-onset and 31 adult-onset patients had AQP4-IgG-positive  neuromyelitis optica spectrum disorder. The mean age of pediatric-onset neuromyelitis optica spectrum disorder was 12  their disease at follow-up. Therefore, pediatric-onset disease may represent a less virulent form of neuromyelitis optica spectrum disorder.

This retrospective study was able to compare and contrast pediatric- and adult-onset neuromyelitis optica spectrum disorder. Relative to their adult counterparts, pediatric-onset neuromyelitis optica spectrum disorder patients were more likely to respond to treatment and less likely to be disabled from their disease at follow-up. Therefore, pediatric-onset disease may represent a less virulent form of neuromyelitis optica spectrum disorder.
