Objective: The purpose of this study was to explore the feasibility to determine regional diagnostic reference levels (RDRLs) for paediatric conventional and CT examinations using the European guidelines and to compare RDRLs derived from weight and age groups, respectively. Methods: Data were collected from 31 hospitals in 4 countries, for 7 examination types for a total of 2978 patients. RDRLs were derived for each weight and age group, respectively, when the total number of patients exceeded 15. Results: It was possible to derive RDRLs for most, but not all, weight-based and age-based groups for the seven examinations. The result using weight-based and age-based groups differed substantially. The RDRLs were lower than or equal to the European and recently published national DRLs. Conclusion: It is feasible to derive RDRLs. However, a thorough review of the clinical indications and methodologies has to be performed previous to data collection. This study does not support the notion that DRLs derived using age and weight groups are exchangeable. Advances in knowledge: Paediatric DRLs should be derived using weight-based groups with access to the actual weight of the patients. DRLs developed using weight differ markedly from those developed with the use of age. There is still a need to harmonize the method to derive solid DRLs for paediatric radiological examinations.

European Guidelines

Objectives: To compare diagnostic reference levels (DRLs) in paediatric fluoroscopy at a secondary referral centre with 2018 European guidelines. Secondly, to compare secondary referral centre DRLs for paediatric fluoroscopy examinations not included in European guidelines with 2010 national UK DRLs. Methods: Paediatric fluoroscopy studies were grouped by age (groups: 0, 1, 5, 10, 15 years) for examination type and analysed retrospectively, over a period of 14 years. DRLs were compared with European DRLs (micturating cystourethrograms (MCUs)) and 2010 UK national DRLs (contrast swallows and meals). Results: 1,586 studies were performed (49% MCUs; 31% meals; 9% swallows). For all age groups, DRLs for MCUs were lower than European DRLs by up to a factor 58 x (1 year age group: secondary referral centre DRL 12 mGycm2 vs European DRL 700 mGycm2). For contrast swallows and meals, 75th percentile doses were lower than 2010 UK national 25th percentile doses in all age groups. Conclusion: Maintaining low doses of ionising radiation is particularly important in paediatrics, and our study has found that it is possible to achieve low paediatric fluoroscopy doses in a secondary referral centre setting. Advances in knowledge: Our data may prove useful to other centres and could contribute towards future European DRLs.

Background: Abnormal uterine bleeding is the most common and frequent presenting complaint in Gynaecology Outpatient Department in all age groups, especially in perimenopausal women. Objective of present study was clinicopathological evaluation and management of abnormal uterine bleeding in perimenopausal age group women.Methods: The present study was prospective analytical study conducted at Mallareddy Narayana Multi-speciality Hospital, reputed teaching hospital, in Obstetrics and gynaecology department in association with department of pathology from January 2015 to December 2016. Perimenopausal women in age group 45-55 years included in this study. Other age groups with abnormal uterine bleeding, isolated cervical or vaginal pathology, bleeding diathesis, and pregnancy related causes of bleeding excluded from this study. Endometrial tissue collected by sampling procedure such as dilatation and curettage. Proper counselling about management was given to all women related to medical and surgical interventional approaches.Results: A total of 135 women with abnormal uterine bleeding in perimenopausal age were examined after fulfilling criteria during study period of 2 years. The age of participants in mean±SD was 46.68±2.03 years (min 45 years and max 55 years). Maximum number of patients with abnormal uterine bleeding presented in age group of 45-50 years. The most common symptoms were heavy menstrual bleeding (83.7%), followed by frequent menstrual bleeding (26.6%). Proliferative endometrium was the most common histopathological (30.3%) study followed by secretory endometrium (27.4%). Surgical management was given to 94 patients.Conclusions: Heavy menstrual bleeding and frequent menstrual bleeding were mostly correlated with abnormal endometrial histopathological findings in this study. Gynaecologists should pay attention towards these abnormal bleeding patterns along with the evaluation of endometrial tissue for histopathological findings, which will help us to plan for successful management.

Abstract To propose Japanese national DRLs for air-kerma at the reference point (Ka,r), air-kerma area product (PKA), fluoroscopy time (FT), and number of cine images (CI) for four age groups. We posted a nationwide questionnaire to 132 facilities. Questions focused on identifying the procedure, age, weight, height, Ka,r, PKA, FT, and CI during diagnostic and therapeutic pediatric cardiac catheterization. For diagnostic cardiac angiography, the 75th percentile values were as follows; Ka,r: 103, 127, 194, and 351 mGy; PKA: 7.0, 12.3, 14.3, and 47.2 Gy.cm2; FT: 36.8, 30.7, 33.4, and 35.7 min; and CI: 2018, 2313, 2408, and 2016 images for less than one year, 1–5 years, 6–10 years, and 11–15 years respectively. For therapeutic cardiac angiography, the 75th percentile values were as follows: Ka,r: 146, 209, 130, and 501 mGy; PKA: 7.54, 16.0, 8.35, and 46.0 Gy.cm2; FT: 56.5, 52.0, 49.4, and 52.0 min; and CI: 4075, 4514, 3576, and 5984 images for less than one year, 1–5 years, 6–10 years, and 11–15 years respectively. Our survey of diagnostic and therapeutic cardiac catheterization in Japanese pediatric patients showed that all age-based Japanese 75th percentiles for the Ka,r, PKA, FT, and CI were higher than in other surveys. Based on the result of our study, it is necessary to establish DRLs for pediatric cardiac catheterization examinations in Japan, in order to optimize the safety of pediatric protocols for diagnostic and therapeutic cardiac catheterization.

As an outpatient appointment, 347 patients (185 men and 162 women) who first sought dental care for chronic generalized periodontitis were examined in the therapeutic department of the Dentistry clinic of the Kirov Military Medical Academy. All patients were divided into three age groups: 40-45 years, 46-50 years, 51-55 years. There were no patients younger than 40 years old and older than 55 years old among the examined ones. When analyzing the results of the examination of patients, it was revealed that the largest number of patients belongs to the age group of 40-45 years (49.3±2.7% of all examined), on the second place was the age group of 46-50 years – 127 (36.6±2.6% of all examined) people (p<0.001), the smallest the group of patients was 51-55 years, 49 (14.2±1.9% of all examined) people (p<0.001). There were no large differences in the number of patients by gender between the age groups (p>0.05). Mild chronic generalized periodontitis prevails among the examined patients (65.1±2.6%, p<0.001). The mild severity of chronic generalized periodontitis was recorded in 121 (65.4±3.5%) of the 185 men, among 162 women – in 106 (64.8±3.8%). Chronic generalized periodontitis of moderate severity was detected in 42 (22.7±3.1%) men and 38 (23.5±3.3%) women. Finally, 22 (11.9±2.4%) men and 19 (11.7±2.5%) women went to the therapeutic department of the dental clinic with severe chronic generalized periodontitis. Thus, there were no large differences between the sexes in the number of patients with different degrees of severity of chronic generalized periodontitis (p>0.05).

 Background: Acute appendicitis is very common surgical cause of acute abdomen and needs surgical removal either by laparoscopic or open appendicectomy. The aim of this study is to compare frequency of surgical site infection (SSI) in patients undergoing laparoscopic and open appendicectomy. Materials and Methods: The study was prospective study conducted in NMCTH, Biratnagar. Total 200 patients with diagnosis of acute appendicitis admitted through the emergency department of our hospital were included in the study. The patients were randomly allocated in two groups: Laparoscopic appendicectomy group (LA) and Open appendicectomy group (OA). Both groups underwent successful emergency appendicectomy. Wound infections in terms of surgical site infection (SSI) if present were recorded. All age groups and both sexes were included.  Results: Two hundred patients underwent appendicectomy, one hundred Laparoscopic appendicectomy (LA) and another hundred open appendicectomy (OA). The mean age of patients with acute appendicitis was 30.63±16.14 years with minimum of 6 years and maximum of 77 years. The highest number of patients were in age group of 10 to 20 years (29.5%). In LA group SSI noted in 3 patients (3%) whereas in OA group it was found in 12 patients (12%). Conclusion: Laparoscopic appendicectomy is better and offers great advantages in terms of SSI as compared to Open appendicectomy.

Abstract In order to establish national diagnostic reference levels for mammography examinations, entrance skin air kerma, entrance skin dose and average glandular doses (AGDs) were calculated for a total of 25 624 cranio-caudal (CC) and mediolateral oblique (MLO) projections of 6309 patients for 40–49 and 50–64 age groups. The average entrance skin air kerma and entrance skin dose values for both age groups were found to be higher in MLO projections compared with CC projections. The minimum and maximum values of AGDs were determined as 0.4 and 7.9 mGy for both projections. The maximum numbers of AGDs for CC and MLO projections were calculated in the range of 1.1–1.5 and 1.6–2.0 mGy, respectively. The third quartile values of AGDs were calculated for each compressed breast thickness between 20 and 99 mm. The first national diagnostic reference levels of the country were established for each 10-mm compressed breast thickness in mammography examinations.

AbstractIn 2017, the 19th World Swimming Championship will be organized in Hungary. Up to now, many people have already been working with swimmers to achieve good results. However, in the next period they must work even harder to ensure that the national swimmers of a country as small as Hungary can achieve the outstanding results of their predecessors. Since high-level competitions in swimming have become more intense, innovations including scientific studies are needed during preparation for the event. The purpose of this paper is to present the major results of an independent study carried out by the authors about the relative age of the best Hungarian swimmers with the aim of contributing to their preparation. The research population consisted of selected age groups of swimmers registered by the Hungarian Swimming Association (N=400). The method for data collection was an analysis of documents. To evaluate the data, the Chi-square and Kruskal-Wallis tests were used. The results are presented according to the period of the competitor’s date of birth, gender, and age group. The results confirm only partly the hypothesis that people born in the first quarters of the year play a dominant role in Hungarian national swimming teams. In the conclusion, the authors recommend further research on relative age in swimming and in other sports.

Currently, fractures of the middle face area remain a serious problem of maxillofacial traumatology because there is not only an increase in the number of injuries to the bones of the facial skull, but also the sever character of these injuries, and an increasing number of post-traumatic complications. This is due to the increase in crime, alcoholism, the proliferation of weapons among the population, the increase in traffic accidents, and injuries in the war zone. The purpose of the study was a retrospective analysis of the features of the damage to the middle face area of patients in a large industrial region. Material and methods. We conducted a retrospective analysis of the injury features of the middle face area in 416 patients who became patients of the department of head and neck surgery for the period from January 1, 2010 to December 31, 2019. Results and discussion. The study results showed that the vast majority (χ2 = 529.9; F = 0.000000; p <0.05) of patients were male. Men had by 79.3 (OR = 79.29; F = 0.000000) times higher risk of middle face injury than women. The risk of traumatic face injury in women increased with the age. Thus, in the group of women aged 61+ it was by 29.6 times higher than in the group of women aged 21-30 (OR = 29.6; F = 0.003203). The greatest number of injuries was observed in the age group of 21-30 years. Assessment of the injury risk in this age group showed that it was by 35.5 times higher than in the group of patients aged 61+ and by 2.1 times higher than in the group aged 31-40. Conclusion. The main etiological factor of injuries of the middle face area was domestic trauma, which was 369 (88.7±1.5)% of cases, which was significantly more (χ2 = 498.5; F = 0.000000; p <0.05) than other types of injuries. The risk of domestic injury was by 61.6 times higher than other types of injury. The study results proved that criminal injuries had the highest frequency among all types of injuries (50% of all types of injuries), fall injury was on second place (38%), and road accidents injuries were on third place (7%). A significant majority of the middle face injuries had men, the number of women with injuries of the middle face area increased significantly with the age. The largest number of patients (71.4%) with injuries of the middle face area occurred in the age groups 21-30 and 31-40, that is people of working age

Abstract BackgroundLittle is known about the gender characteristics and the Corona Virus Disease 2019(COVID-19) impact on psychiatric department outpatients in general hospitals in China. MethodsWe retrospectively collected 225,947 outpatient clinic records before and during COVID-19 pandemic from January 1, 2019 to December 31, 2020 in the psychiatric clinic of 3 general hospitals, gender composition of patients was analyzed in different five age groups and nine diagnostic categories at three levels: total patient visits, number of patients and number of first-visit patients. ResultsThe total male-to-female ratio of psychiatric outpatient records in 3 general hospitals from 2019 to 2020 was 1:1.69. Women were more common in all age groups and the male-to-female ratio of 2020 was expanded compared to that of 2019, especially in age group below 34 years old and anxiety disorders category. Most mental disorders showed higher demands for females than that for males except Mental and behavioral disorders due to psychoactive substance use with the male-to-female ratio was 1:0.05. Compared to 2019, the proportions of women were expanded especially in age group below 34 years old, and anxiety disorder and undetermined diagnosis categories were significantly increased in 2020. ConclusionsThe demand for female psychiatric outpatient services is obviously higher than that for males. It is necessary to pay more attention to explore targeted mechanism or psychosocial service strategy for female patients with mental disorders. Trial registration: ChiCTR2100044894, March 31,2021 retrospectively registered.
