One of the three patients underwent a third successful ganglion cyst excision. The other two patients declined surgical intervention to date. Patients without a second recurrence (n=17) reported an average pain score of 0.1 (range 0-2) on a scale of 1-10. Three (18%) reported some difficulty with day-to-day activities due to their scar. Seven (41%) patients reported at least transient numbness or tingling. Mean satisfaction was 9.8 on a scale of 1-10, and 100% reported that they would undergo another ganglion cyst excision should they ever have another recurrence.

Patients should be advised about the risk of recurrence after re-excision of ganglion cysts, which was noted to be 15% in our cohort. This rate of recurrence is similar to that of primarily excised cysts.

The purpose of this article is to perform a narrative review of the literature with the aim of answering the following question What are the main factors contributing to patient dissatisfaction after TKA? A review of the literature was performed on patient satisfaction after TKA. The search engines used were MedLine (PubMed) and the Cochrane Library. The keywords used were "TKA" and "satisfaction". The main reported preoperative factors positively contributing to patient satisfaction were the following fulfilment of preoperative expectations, preoperative complete joint space collapse, increasing patellar and lateral compartment osteophyte size, and TKA communication checklist. The principal preoperative factors negatively contributing to patient satisfaction included female sex, comorbidities, and Hispanic race. The chief perioperative factor positively contributing to patient satisfaction was cosmetic closure, whereas the fundamental perioperative factors negatively contributing to patient satisfaction included joint laxity, anterior tibial component slope, and greater femoral component valgus angle. The principal postoperative factors positively contributing to patient satisfaction were the following ameliorated walking distance, improved range of motion, and improvements in pain. The most important postoperative factors negatively contributing to patient satisfaction included poor postoperative knee stability and soft-tissue balance, functional limitation, surgical complication and reoperation, staff or quality of care issues, and increased stiffness.In this paper we present the findings of a literature review covering articles published in the last three decades describing the application of telemedicine in orthopaedics. A review of the PubMed Central and Medline provided 75 articles studying the role of telemedicine, the majority directly examining the application of telemedicine in orthopaedic patients. We report the summarized findings of these studies, the financial and HIPAA considerations of using telemedicine, and provide an example of our single urban level-1 trauma center's strategy for incorporating telemedicine into the clinical practice of orthopaedic surgeons during the COVID-19 pandemic.
Electronic cigarette (ECIG)-generated aerosol contains particulate matter with a diameter less than 2.5 microns (PM
). Particles of this size may be injurious to the health of those who inhale them. Few studies have assessed the relationship between ECIG aerosol PM
and ECIG liquid ingredients or ECIG device power.

Two studies were conducted in which participants generated aerosols with ECIGs in one, ECIG liquids contained various vegetable glycerin/propylene glycol ratios and in the other, ECIG devices varied by electrical power output.

Results indicate that, in general, PM
increases as the ratio of vegetable glycerin to propylene glycol increases, or as device power increases.

Regulating ECIG PM
emissions to protect non-users requires an understanding of all the factors that influence these emissions.

Past research has not examined secondhand and thirdhand smoke (THS) exposure in children of cigar smokers. We examined hand nicotine and cotinine levels in children of cigar smokers to explore the contribution of cigar smoke to tobacco smoke exposure (TSE).

Participants were children (N = 24; mean (SD) age = 6.5 (3.6) years) whose parents smoked cigars only or poly-used cigars and/or cigarettes. Primary outcomes were hand nicotine and urinary cotinine levels.

All children had detectable hand nicotine (range 7.6-312.5ng/wipe) and cotinine (range 0.3-100.3ng/ml). Positive correlations were found between hand nicotine and cotinine (r = 0.693, p = .001), hand nicotine and parents who also smoked cigarettes (r = 0.407, p = .048), and hand nicotine and number of smokers around the child (r = 0.436, p = .03). Hand nicotine (r = -0.464, p = .02), but not cotinine (r = -0.266, p = .26), was negatively correlated with child age. Multiple regression results indicated a positive association between hand nicotine and cotinine (p = .002; semi-partial r
= 0.415), irrespective of child age.

The significant association of hand nicotine with urinary cotinine suggests that THS pollution should be assessed in evaluating children's overall TSE to cigars and other tobacco products, and hand nicotine may be a proxy for overall TSE. Younger children may have increased THS pollutant uptake.

This study's objective was to characterize the nicotine delivery profile of a variable voltage, tank-style electronic nicotine delivery system (ENDS).

Ten cigarette smokers (8 men, 2 women) completed this within-subject study assessing effects of 2 device power settings (15 W, 45 W) and 3 liquid nicotine concentrations (0, 3, and 6 mg/ml) using a tank-style ENDS. Participants completed one directed (10 puffs) and one
use period for each condition, with blood sampled throughout.

Plasma nicotine concentration did not increase significantly at 15 W regardless of liquid nicotine concentration. At 45 W, mean plasma nicotine increased (not significantly compared to 0 mg/ml) from 2.24 ng/ml (SD=0.2) at baseline to 3.4 ng/ml (SD=0.6) in the 3 mg/ml condition. In the 6 mg/ml, 45 W condition, mean plasma nicotine increased significantly (compared to 0 mg/ml) from 2.0 ng/ml (SD=0) at baseline to 5.96 ng/ml (SD=1.3) after 10 puffs. In general, puff duration and volume decreased as device power and nicotine concentration increased.

Despite using a variable wattage, tank-style device, nicotine delivery was minimal. These results, when combined with results from other studies using tank-style devices, highlight ENDS performance heterogeneity. Regulation may play a role in standardizing ENDS nicotine delivery.

It is the main cause of child morbidity and mortality especially in sub-Saharan Africa including Ethiopia. The severity of the problem is even worse when children are infected with human immunodeficiency virus. However the seriousness of the problem, there were limited studies conducted in the study area. Therefore, this study was conducted to assess the magnitude of undernutrition and its associated factors among HIV-infected children on follow up in Amhara Region Referral Hospitals. Methods. A facility-based cross-sectional study was conducted from February to April 2020. The data were collected through an interviewer-administered questionnaire. The collected data were coded and entered into Epi data 3.1 and exported to SPSS 26.0 for analysis. P-value less then .05 was considered as statically significant. Results. The magnitude of undernutrition in this study was 30.3%. Dietary diversity (AOR = 1.73; CI 1.07-2.81), nutritional counseling (AOR = 2.42; CI 1.45-4.04), family size (AOR = 0.50; CI 0.27-0.93), WHO staging (AOR = 1.77; CI 1.08-2.88), and adherence to antiretroviral therapy (AOR = 1.75; CI 1.06-2.87) were predictors of undernutrition. Conclusions. Nearly one-third of the children included in this study had undernutrition. Poor dietary diversity, adherence to ART, nutritional counseling, family size, and WHO staging were factors significantly associated with undernutrition. Early screening and treatment of opportunistic infections, close attention to dietary counseling for caregivers and proper feeding habits will alleviate the problem.Global mobility has been steadily increasing in recent years. The assessment of the febrile child returning from international travel is a diagnostic challenge. The COVID-19 pandemic has profoundly affected international travel and made evaluation and management of the sick returned traveler more challenging. Children visiting friends and relatives abroad remain at higher risk of infection compared to tourists. This review presents a guidance on the initial assessment of a traveling febrile child including interpretation of medical history, physical examination, and laboratory findings. Important clues to etiology include exposure to different infectious agents, incubation periods of pathogens, and prophylaxis regimens and vaccines received. Early identification of potentially life-threatening and highly contagious infections is essential. In this article, we discuss the epidemiology, evaluation, and management of specific travel related infections such as malaria, typhoid fever, dengue fever, viral hemorrhagic fever, rickettsiosis, leptospirosis, schistosomiasis, gastrointestinal, and respiratory infections.To determine the association between tobacco consumption and self-reported visual impairment. We performed a cross-sectional study based on an original cohort study. A non-probabilistic sampling was performed to invite 413 patients of 60 years or more from 11 high-altitude Andean communities (altitude higher than 1500 m above sea level) of Peru between 2013 and 2017. Demographic data and information on tobacco consumption were collected. Associations were determined using a Poisson regression model with 95% confidence intervals (CI). Of the 413 participants, 141 (34.14%) were men and 49 (11.86%) were tobacco users. In the adjusted model, tobacco users presented a high probability of visual impairment with a prevalence ratio of 1.32 (95% CI 1.18-1.97). We also found that having two or more comorbidities 2.19 (95% CI 1.53-3.15), receiving health assistance in a pharmacy 3.75 (95% CI 1.97-7.16), and coffee consumption 1.67 (95% CI 1.26-2.21) were factors significantly associated with self-reported visual impairment.
