Abstract We identify the yearly trends in the prevalence of various ocular traumas in the Republic of Korea, and the effects of Covid-19. We recorded the yearly numbers of patients diagnosed with hyphema and those who underwent open reduction surgery because of orbital blowout fracture (BOF), primary closure of the cornea or sclera (PCCS), or intraocular foreign body (IOFB) removal. The incidence of closed globe injuries has decreased significantly over the past 10 years, while that of open globe injuries has not. The patients aged ≥ 60 years showed a significant increase in BOF surgery. Regarding the trend in PCCS, while other age groups showed significant decreases, the population aged ≥ 60 years did not. In addition, the population aged ≥ 60 years showed a significant increase in the incidence of IOFB. When the 2020 data were compared with those of 2019, hyphema evidenced the largest decrease (27.02%), especially in those aged < 20 years (54.33%). In terms of both BOF and IOFB, those aged < 20 years showed the largest decreases (28.85% and 47.93% respectively). In the Covid-19 era, ocular trauma fell markedly in those aged < 20 years, perhaps because of school closures and reductions in outdoor activities.

Abstract Background: The epidemiological characteristics of Multiple Sclerosis (MS) in various studies have been investigated and studies suggested that there is a different geographic disparity worldwide. The present study conducted to investigate the longitudinal prevalence of MS in Tehran, Iran. Methods: The population-based study was conducted in Tehran, the capital of Iran from 1999 to 2018 based on the annual report data through the Iranian MS Society (IMSS) registry system. The age-standardized and crude prevalence proportions were estimated by applicant of population data, established from the Statistical Centre of Iran. Results: Totally 21,580 MS cases were registered and included in the analysis. Out of them, 24.99% (5,393 cases) was male and 75.01% (16,187 cases) was female. The mean age of MS onset was 28.8 years (S.D: 8.7). The age standardized prevalence proportion (ASP) of MS ranged from 73.7 (95%CI: 72.1-75.2) in 2006 to 137.6 (95% CI: 135.7-139.5) per 100,000 in 2018. The MS ASP- was estimated 54.1 (95%CI: 53.6-54.6) among males and 174.5 (95%CI: 173.6-175.4) per 100,000 among females. The age standardized female to male ratio of MS in study period was 3.03. Conclusion: Our finding suggested that the prevalence of MS in Tehran province is relatively high and the disease occurrence is more common in the under-40 age group than in the older ones. As in the rest of the world, the prevalence of the MS was higher in women, and the female to male sex ratio was 3.03 in our study.

PurposeTo describe the prevalence, subtypes, severity and determinants of ocular trauma (OT) in a population-based study in Singapore.MethodsWe included 3353 Chinese adults aged ≥40 years from the Singapore Chinese Eye Study, a population-based study, conducted between 2009 and 2011. OT was defined as self-reported history of any eye injury requiring medical attention with or without hospitalisation, and further classified as blunt object, sharp object or chemical burns related. Age and gender-standardised prevalence was estimated using the 2010 Singapore Chinese population census. Multivariable models were used to assess the independent associations of OT with age, gender, income, education, literacy, alcohol consumption, smoking and history of falls.ResultsThe mean (SD) age was 59.7 (9.9) years and 49.4% were male. There were 138 OT cases, giving a crude and age and gender-standardised prevalence of 4.1% (95% CI 3.5% to 4.8%) and 4.4% (95% CI 3.7% to 5.2%), respectively. Of these, 45 (32.6%), 56 (40.6%) and 10 (7.3%) were blunt object, sharp object and chemical burns-related trauma, respectively. Twenty eight (20.3%) required hospitalisation, with no difference between subtypes. In multivariable models, men (OR (95% CI): 2.80 (1.79–4.39)), younger persons (per year decrease in age (1.03 (1.00–1.05)) and lower education levels (1.8 (1.25–2.60); comparing ≤6 years vs >6 years of education) were independent determinants of OT.ConclusionsOT affected one in 25 adults, with 20% of these requiring hospitalisation. Because OT is preventable, raising awareness and education strategies in the population would allow prevention of vision loss particularly in men, and younger and lesser-educated individuals.

Abstract Background: The epidemiological characteristics of multiple sclerosis (MS) have been investigated in various studies, which have revealed that the prevalence of MS varies across countries. The present study was conducted to investigate the longitudinal prevalence of MS in Tehran, Iran. Methods: The present population-based study was conducted in Tehran, the capital of Iran from 1999 to 2018 based on the annual report data provided by the Iranian MS Society (IMSS) registry system. The age-standardized and crude prevalence were estimated using population data presented by the Statistical Centre of Iran. Results: A total of 21,580 MS cases were registered and included in the analysis. Among the participant patients, 24.99% (5,393) and 75.01% (16,187) of cases were male and female, respectively. The mean age of MS onset was 28.8 years (S.D: 8.7). The age-standardized prevalence (ASP) of MS increased from 73.7 (95%CI: 72.1-75.2) per 100,000 people in 2006 to 137.6 (95% CI: 135.7-139.5) per 100,000 people in 2018. The ASP of MS in 2018 was estimated to be 67.9 (95%CI: 66.0-69.8) and 207.3 (95%CI: 204.0-210.7) per 100,000 people among males and females, respectively. The age-standardized female-to-male ratio of MS ranged from 3.7 (in 2010) to 2.06 (in 2017). Conclusion: The findings of this study suggested that the prevalence of MS in Tehran province is relatively high, and the occurrence of the disease is more common in the age groups under 40 years as compared with older-aged groups. In line with reports provided for various regions of the world, the prevalence of MS was higher among women. Similarly, the findings of this study revealed that the female-to-male ratio was 2.14 in 2018.

Antepartum Stillbirth

(1) Background: Across Europe, the incidence of antepartum stillbirth varies greatly, partly because of heterogeneous definitions regarding gestational weeks and differences in legislation. With this study, we sought to provide a comprehensive overview on the demographics of antepartum stillbirth in Austria, defined as non-iatrogenic fetal demise ≥22+0 gestational weeks (/40). (2) Methods: We conducted a population-based study on epidemiological characteristics of singleton antepartum stillbirth in Austria between January 2008 and December 2020. Data were derived from the validated Austrian Birth Registry. (3) Results: From January 2008 through December 2020, the antepartum stillbirth rate ≥20+0/40 was 3.10, ≥22+0/40 3.14, and ≥24+0/40 2.83 per 1000 births in Austria. The highest incidence was recorded in the federal states of Vienna, Styria, and Lower and Upper Austria, contributing to 71.9% of all stillbirths in the country. In the last decade, significant fluctuations in incidence were noted: from 2011 to 2012, the rate significantly declined from 3.40 to 3.07‰, whilst it significantly increased from 2.76 to 3.49‰ between 2019 and 2020. The median gestational age of antepartum stillbirth in Austria was 33+0 (27+2–37+4) weeks. Stillbirth rates ≤26/40 ranged from 164.98 to 334.18‰, whilst the lowest rates of 0.58–8.4‰ were observed ≥36/40. The main demographic risk factors were maternal obesity and low parity. (4) Conclusions: In Austria, the antepartum stillbirth rate has remained relatively stable at 2.83–3.10 per 1000 births for the last decade, despite a significant decline in 2012 and an increase in 2020.
