Aim: The aim of the study was to demonstrate the prevalence and risk factors of dry eye symptoms (DES) among university students in Poland. Material and methods: A cross-sectional study survey was conducted among 312 Polish university students. The questionnaire consisted of the Ocular Surface Disease Index (OSDI), the 5-Item Dry Eye Questionnaire (DEQ-5) and questions regarding medical history and risk factors. Results: According to the OSDI, more than half of respondents (57.1%) have symptoms of ocular surface disease. Time spent using electronic devices is correlated with scores gathered in both OSDI and DEQ-5 (p < 0.001). There is a statistically significant dependence between psychotropics (p = 0.002), glucocorticosteroids usage (p = 0.026), the presence of depression (p < 0.001), diabetes (p = 0.01) or allergy (p = 0.008) and dry eye symptoms proved in both questionnaires. Respondents with refractive errors and those living in metropolitan areas have a statistically higher symptom intensity(p < 0.022). Stress felt by students is associated with higher DES risk. No correlation between DES and smoking habits was observed. The history of SARS-CoV-2 infection was associated with the severity of DES (p = 0.036). Conclusion: Pathogenesis of DES is multifactorial and its severity depends on several factors, both genetic and environmental. Its prevalence among the young population is underestimated. Determining risk factors will enable the implementation of appropriate prophylaxis and early diagnosis.

Introduction and purpose. Due to the outbreak of Covid-19 pandemic polish government in March 2020 decided to directs students to remote learning. This condition last -with minor exceptions- one and half year.Material and method. The aim of the study was an evaluation of public experience and attitude towards online learning.Results. All the respondents between March and May 2020 learned via online devices. The average note for e-learning was 2,99 in a 5-grade scale, while a score for stationary learning was 3,84. Students motivation, engagement and stress level decreased during remote-learning. 43% students claimed, that their marks improved during that time. The main disadvantages of online school were too much time spent in front of the screen and monotony of the lessons. Among the advantages was for example time for additional hobbies. Realisation of practical activities was more difficult or impossible for 74,9% of the respondents. Almost one quarter of the people did not have adequate home conditions to study online. Practical activities were often difficult or impossible to realise.Conclusions. Online learning was a necessity during the pandemic, however this type or gaining knowledge has both advantages and disadvantages. It influenced not only scientific issues, but also students’ motivation and sociopsychological aspects. To conclude, twice as many students prefer stationary than online learning – respectively 39,7% vs 21,1%.

Introduction and objective Myopia is a defect of vision, which makes it impossible to see remote objects clearly. The disease can also lead to serious ocular problems. Myopia affects about 30% of the world population and -according to the estimates- that percentage is about to increase up to 50% within the next 30 years. Orthokeratology is a relatively new method on non-surgical, reversible correction of myopia. Specially designed lenses, worn at night, affects the shape of the cornea, which results in proper vision during the day. Review methods The aim of the study was evaluation of effectiveness of wearing orthokeratology contact lenses based on a review of medical literature published on PubMed in the last 5 years. Abbreviated description of the state of knowledge Research results show that wearing orthokeratology lenses have beneficial effects. Reduction of axial length of the eyeball and curvature of the cornea were observed. Progression of myopia was five times slower in children study group and three times slower in adult study group compared to control groups. It was proved, that favourable health effects persist through the first eight years of treatment. Due to the fact, that cornea has a limited susceptibility, a decrease in efficiency occurs in the following years. Usually no undesirable side effects are reported, yet the possible side effects are mild and disappear after a short time. Summary According to the results of recent studies, we can assume that orthokeratology is a safe and effective method of inhibition of myopia progression. The method may be especially recommended to children, to people working in such conditions, that make wearing standard contact lenses impossible and to people not qualified for laser or surgical vision correction.

Preeclampsia (PE) is a pregnancy complication that affects 5% to 8% of all pregnancies. It is a leading cause of maternal mortality that contributes annually more than 60,000 maternal deaths all over the world. Data submitted so far by clinicians are still insufficient to completely understand the disease. Despite many researches, the prediction of patients suffering from PE remains difficult. Moreover therapeutic methods are also limited and concentrated on symptomatic treatment and early termination of pregnancy. The  aim  of  the  presented  article  is  to  review  current research on the PE and its long-term effects on mother and child. PE is defined as a hypertension developing after 20 weeks of gestation with at least one of the following symptoms: proteinuria, maternal organ dysfunction or foetal growth restriction. Because initially patients may be completely asymptomatic, the diagnosis is usually difficult. Untreated PE may lead to the death of both mother and neonate. In later life it predisposes woman and child to cardiovascular and metabolic diseases. Maternal consequences are related to increased risk of hypertension, stroke, thrombosis or chronic kidney disease, whilst offspring implications are directly correlated with hypertension, increased body mass index, hormonal changes and reductions in cognitive functions. In the future there is a need to develop more effective diagnostic methods of PE. Comprehensive understanding of the pathophysiology would allow to avoid many negative long-term effects and reduce its mortality rate.

Lipoedema is a chronic progressive disorder of adipose tissue leading to an enlargement of lower extremities. It is considered to be rare; however, the prevalence of the disease is underestimated because it is commonly misdiagnosed as obesity or lymphedema and the general awareness is poor. The etiology of the disorder is considered to be multifarious, including genetic inheritance, hormonal imbalance and microcirculation alterations. Diagnosis is mainly based on medical history and physical examination. Management of lipoedema is focused on reducing the symptoms, improving the quality of life and preventing further progression of the disease. The aim of this paper is to raise the awareness of the disease and provide appropriate clinical guidance for the assessment of lipoedema. We searched through the PubMed/MEDLINE database and took into consideration all of the results available as of 6 September, 2020 and outlined the current evidence regarding lipoedema epidemiology, etiology, clinical presentation, differential diagnosis, and management. Better understanding of lipoedema is crucial for establishing an early diagnosis and a proper treatment, which in turn will reduce the psychological and physical implications associated with the disease.
