BackgroundPediatric anesthesiology has been greatly impacted by COVID-19 in the delivery of care to patients and to the individual providers. With this study, we sought to survey pediatric centers and highlight the variations in care related to perioperative medicine during the COVID-19 pandemic, including the availability of protective equipment, the practice of pediatric anesthesia, and economic impact.AimThe aim of the survey was to determine how COVID-19 directly impacted pediatric anesthesia practices during the study period.MethodsA survey concerning four major domains (testing, safety, clinical management/policy, economics) was developed. It was pilot tested for clarity and content by members of the Pediatric Anesthesia COVID-19 Collaborative. The survey was administered by email to all Pediatric Anesthesia COVID-19 Collaborative members on September 1, 2020. Respondents had six weeks to complete the survey and were instructed to answer the questions based on their institution's practice during September 1 - October 13, 2020.ResultsSixty-three institutions (100% response rate) participated in the COVID-19 Pediatric Anesthesia Survey. Forty-one hospitals (65%) were from the United States, and 35% included other countries. N95 masks were available to anesthesia teams at 91% of institutions (n = 57) (95% CI: 80%-96%). COVID-19 testing criteria of anesthesia staff and guidelines to return to work varied by institution. Structured simulation training aimed at improving COVID-19 safety and patient care occurred at 62% of institutions (n = 39). Pediatric anesthesiologists were economically affected by a reduction in their employer benefits and restriction of travel due to employer imposed quarantine regulations.ConclusionOur data indicate that the COVID-19 pandemic has impacted the testing, safety, clinical management, and economics of pediatric anesthesia practice. Further investigation into the long-term consequences for the specialty is indicated.

Abstract Background Head and neck cancers are a major cancer burden in Pakistan. They share a common risk factor profile including regular consumption of products of betel, areca and tobacco. Use of paan, chaalia, gutka, niswar and tumbaku is acceptable in Pakistan and is considered a normal cultural practice. This cross-sectional study was carried out to understand the relation of socio-demographic factors for the consumption of paan, chaalia, gutka, niswar and tumbaku in Pakistani population. Through systematic sampling, 425 subjects from a squatter settlement in Karachi were interviewed using a structured questionnaire. High risk behavior was defined as Daily use of any of the above products. Results Daily use of all the substances except chaalia was higher among males compared to females. Chaalia use was higher among adolescents than adults while non-married consumed both chaalia and gutka more than married. Mohajir ethnicity had higher prevalence of paan, gutka and tumbaku use while Pathans had higher prevalence of niswar use. Conclusion Prevalence of use of chewable products is high in Pakistan with particularly high use of certain substances related with socio-demographic profiles. Industrially prepared products, chaalia and gutka, are gaining popularity among youth. Policies and focused interventions can be developed taking into consideration the preferred use of products among different socio-demographic groups.

Objectives: To identify biopsy rates and indications for BI‐RADS 3 lesions in a large cohort of patients and compare with follow‐up compliance and malignancy outcomes. Methods: We retrospectively reviewed all BI‐RADS category‐3 lesions seen on mammography and/or ultrasound between 2013 and 2015. Patient age, lesion size, follow‐up rates at 6‐, 12‐, and 24‐months were collected. Biopsy timing, indication, and outcomes (malignant vs benign) were recorded using at least 2‐year follow‐up or biopsy pathology as endpoint. Results: Of 2319 BI‐RADS 3 lesions in 2075 women analyzed, biopsy was performed in 173 (7.5%). Most biopsies were performed upfront (99, 57.2%), followed by at 6 (44, 25.4%), 12 (21, 12.1%), and 24‐month follow‐up (9, 5.2%; P <.001). Palpable (P <.001) and larger (median 1.4 vs 1.0 cm, P <.001) lesions in women <40 years (15.2% vs 4.8%, P <.001) were more likely to undergo biopsy. Most biopsies were prompted by patient/physician desire (64.5%, P <.001). Of 783 lesions with available endpoint, 5 (0.6%) were cancer. All cancers were identified either at presentation (in 0–5 months, n = 1) or 6‐month follow‐up (in 5–9 months, n = 4) with biopsy prompted by either morphology change (n = 3) or lesion growth (n = 2). Of the 1855 lesions which were expected for follow up, only 310 (16.7%) underwent all follow‐ups, while 482 (26.1%) had two, 489 (26.5%) one, and 565 (30.6%) had no follow‐up. Conclusions: In our cohort, BI‐RADS category 3 lesions had significantly higher biopsy rates compared with the small malignancy rate, all of which were identified at baseline or first follow‐up. Overall patient follow‐up compliance low. Imaging follow‐up, especially at first 6‐month time point, should be encouraged in BI‐RADS 3 lesions, instead of upfront biopsies. [ABSTRACT FROM AUTHOR]

The link of betel, areca and chewable tobacco with head and neck cancers is clearly established. Fifty eight percent of the global head and neck cancers occur in South and Southeast Asia, where chewing of betel, areca and tobacco are common. This study was carried out to establish the pattern of use of Paan, Chaalia, Gutka, Niswar, Tumbaku and Naas among population of squatter settlement of Karachi and to determine the perceptions and knowledge regarding their role in the etiology of head and neck cancers. It was a cross-sectional study, performed at Bilal colony in Karachi. Through systematic sampling, 425 subjects [a male and female from a household] were interviewed with a structured questionnaire. Knowledge regarding etiology of head and neck cancers was classified in ordinals of "good", "some" and "poor", for each substance separately, while practices were classified into "daily user", "occasional user" and "never user". About 40% of the participants were chewing at least one item [betel, areca or tobacco products] on daily basis. This prevalence was 2.46 times higher among males than females and 1.39 times higher among adolescents than adults. At least 79% of the participants were classified as having poor knowledge about the carcinogenicity of each of these items. Knowledge increased with age and level of education. Health hazards of these items were poorly recognized and about 20% perceived at least one of these items to be beneficial. Positive attitudes were seen regarding the steps to curb the production, business and consumption of these substances. In conclusion, prevalence of chewing of betel, areca and tobacco among adults and adolescents is high. Deficiency in knowledge and wrong perception of favorable effect of chewing products is common. Besides curtailing the availability of chewing products, correct knowledge regarding its ill-effects should be inculcated among population to decrease the burden of head and neck cancers.
