Introduction and objective. Congenital herpes simplex virus infection (cHSV) is a rare entity and may pose a life-threatening disease for the newborns. Due to the public health and clinical importance of cHSV infection in infants, the recent data on this disease in Poland should be investigated. The aim of the study was to evaluate the incidence and other factors related to cHSV. Materials and method. The study is retrospective, population-based that utilised the hospital discharge records of cHSV patients. Data were obtained from National Institute of Public Health NIH -- National Research Institute in Warsaw, Poland, covering the period 2014-2019. Results. The study group consisted of 1,573 cHSV newborns (841 males and 732 females). Among this group, 70.1% were infants up to 90 days of age and 3.6% were neonates up to 28 days of age. The mean and median age was 98 days (95% CI: 94.5-101.8, SD 74) and 70 days (IQR: 53-104), respectively. Based on the hospital registry the overall average cHSV incidence over the study period was estimated to be 69 per 100,000 live births. The number of cHSV infection fluctuated over the years 2014-2019 with a significant decreasing trend from 2015-2019 (P<0.01). A significantly higher cHSV incidence was observed among patients from urban than rural areas of Poland (88 vs 40/100,000 live births; P<0.001). Conclusions. CHSV incidence may be related to multifactorial conditions for the occurrence of this disease. Further studies on changes in the incidence of cHSV are needed. [ABSTRACT FROM AUTHOR]

Introduction and objective. Occupational asbestos exposure is one of the major public health issues. Although asbestos use in Poland has decreased, asbestosis continues to remain an important health concern in the area of occupational medicine. The aim of the study is to perform a descriptive analysis of hospitalization cases in patients suffering from asbestosis in Poland. Materials and method. The authors used hospital discharge records to conduct a retrospective, population-based study. To estimate the asbestosis hospitalization rate, data from the Nationwide General Hospital Morbidity Study conducted by the National Institute of Public Health were used. Events were defined as in-patient hospital discharges during 2006–2016. 1,101 hospitalization records of 764 patients were included in the study. Results. In the study group of first-time hospitalized patients, the mean and median ages were 68.1 and 69 years, respectively; CI: 67.3–68.9; SD: 11.1, min-max:16–99 years. In this group, significant gender differences were observed (560 males vs. 204 female; P<0.001). No statistical differences were observed regarding the place of residence. During the observation period, 61 in-hospital deaths were reported (8% of all patients), 40 of whom (5.2 % of all patients) took place during the first-time hospitalizations. Asbestosis hospitalizations were mainly clustered in the south-western region, whereas the highest hospitalization rates were clustered in several areas of Poland. Conclusions. The authors believe this study to be the first evaluation of asbestosis in Poland made on the basis of the hospital morbidity database. The data presented may be helpful in comparative studies on the epidemiology of asbestosis across European countries. [ABSTRACT FROM AUTHOR]

Introduction. Takayasu’s arteritis (TA) is a rare and potentially life-threatening granulomatous large-vessel vasculitis that involves mostly in the aorta and its proximal branches, and occurs most commonly in young females. This study measures the incidence and prevalence of TA, and assesses the gender distribution and territorial differences in the occurrences of this disease in Poland over a five-year period. To the best of our knowledge, this is the first evaluation of this rare disease in Poland based on a hospital morbidity database. Materials and method. Analyses were performed with population-based administrative data obtained from a national hospital morbidity study carried out between January 2011 – December 2015 by the Polish National Institute of Public Health. Yearly incidence rates and prevalence of TA were calculated using the number of TA patients and corresponding census data for the overall Polish population. Results. Data included 660 hospitalization records. The final study sample comprised 177 patients: 154 female (87%) and 23 male (13%) with first-time hospitalization for TA. The mean age was 45.4years (95% CI: 42.9–47.8; SD 16.8; range 4–81 years), median 47. The incidence rate of TA was estimated at 0.92 per million per year (95% CI: 0.68–1.16). Five-year TA prevalence was estimated to be 4,6 per million. Incidence rates of TA did not vary significantly between more urban and more rural regions. Conclusions. The incidence of TA in Poland was similar or lower to data reported by other European countries. The study provides epidemiological data on TA in Poland that may be useful while comparing it with other geographical regions. [ABSTRACT FROM AUTHOR]

Introduction. Paget's disease (PDB) is a focal disorder of bone remodeling that occurs commonly in older people with decreasing prevalence reported in European countries. This disease is most often asymptomatic, but it can cause a variety of medical complications resulting in considerable morbidity and reduced quality of life. There is little information regarding the epidemiology of PDB in Poland. To the best of the authors' knowledge, this is the first large epidemiological analysis of this disease in Poland. Objective. The aim of this study was to analyze factors that may be related to the PDB epidemiology among hospitalized patients in Poland. Materials and method. The analysis was conducted on the basis of population-based administrative data, taken from a Polish hospital morbidity study carried out by the National Institute of Public Health between January 2008 - December 2014. Results. Analyzed data covered 662 hospitalization records. The final study sample comprised 94 (41.8%) male and 131 (58.2%) female patients with first-time hospitalizations for PDB, with a significant predominance of females (P<0.02), and the predominance of patients living in urban (73%) than in rural areas (27%), P<0.001. The average age of the sample was 56.8 years (CI: 54.3-59.3; SD 18.8; range 1-93 years). The number of PDB cases hospitalized in Poland significantly decreased during the analyzed period of time. Conclusions: PDB is a rare disease with decreasing trends observed among hospitalized patients in Poland. The study results may suggest the existence of environmental risk factors for the development of PDB. [ABSTRACT FROM AUTHOR]
