Can Lactose Intolerance Be a Cause of Constipation? A Narrative Review.

Lactose intolerance and constipation are common in children and impact everyday life, not only for patients but also their families. Both conditions can be comorbid with other diseases or form a part of their clinical presentation, but constipation is not usually associated with lactose intolerance. The typical symptoms of lactose intolerance include abdominal pain, bloating, flatus, diarrhoea, borborygmi, and less frequently nausea and vomiting. In approximately 30% of cases, constipation can be a symptom of lactose intolerance. Constipation is characterized by infrequent bowel movements, hard and/or large stools, painful defecation, and faecal incontinence, and is often accompanied by abdominal pain. This paper provides a narrative review on lactose intolerance, its epidemiology, pathogenesis, the correlation between lactose intolerance and constipation in children, and potential mechanisms of such association.

Does Informal Education Training Increase Awareness of Anaphylaxis among Students of Medicine? Before-After Survey Study.

Allergies are among the most common chronic diseases in Europe. The most serious complication is anaphylactic shock. Most cases occur outside the hospital; thus, knowledge of symptoms and first aid is crucial. This study aimed to evaluate the awareness of anaphylaxis and the ability to use adrenaline auto-injectors among medical students, and to determine an improvement after training based on non-formal education. The research was conducted among 364 medicine students (years 1-5) from the Medical University of Gdansk, with year-specific curriculum-based general medical knowledge. Training consisted of pre-test, practical training and post-test. Descriptive statistics were used to reveal the characteristics of students from different grades. A Mann-Whitney U test was used for statistical analysis. The tested students did not have sufficient knowledge to provide first aid in cases of anaphylaxis before training. There was an increase in knowledge (on average, 28.6%, p = 0.005) after training. Almost all (99.4%) of the respondents believed that they would be able to use an adrenaline auto-injector in case of emergency after the training. The training based on non-formal education was effective. The use of the subject-performed task method helped students to remember the stages of action in stressful situations.

Before-and-after online community survey on knowledge and perception of COVID-19 pandemic.

BACKGROUND: COVID-19 pandemic impacts many communities worldwide. In this study the Poles' knowledge about COVID-19 as well as people's behaviours, attitudes and fears during the pandemic were assessed. Changes in these between the outset of the pandemic and the imposition of the strictest lockdown measures in Poland were investigated. METHODS: Physicians, nurses, students of medicine-oriented faculties, non-medical professionals, students of non-medicine-oriented faculties and secondary school students were surveyed by an anonymous online questionnaire two times: at the onset of the pandemic and in the second week of the strictest lockdown. Statistical analyses were performed using non-parametric tests - Pearson Chi Square, Kruskal-Wallis tests. RESULTS: In total 2618 responses were collected. At the beginning people knew that the respiratory system was attacked (97.9%); correctly identified the major symptoms of COVID-19 (95.0%) and ways to prevent infection: hand washing (99.8%), covering mouth (85.9%) and the need to call sanitary-epidemiological services if one experienced COVID-19-like symptoms (92.1%). The biggest changes between the first and second phase of the study concerned behaviours: more people wearing facial masks (+ 37.5%) and staying at home (+ 66.1%). Respondents in the second wave of the survey were also more scared of the pandemic (+ 19.6%), economic crisis (+ 64.1%), and worried about their families (+ 26.5%). However, they were less afraid of the quarantine (lockdown) (- 18.2%). Nurses and physicians were the most worried groups. CONCLUSIONS: The study showed that even at the outset of the pandemic Polish population had a good initial knowledge about symptoms, transmission, and preventive behaviours regarding COVID-19. People revealed more short-term concerns, such as the worries about coping with quarantine and isolation. After a month, the knowledge and the concerns among the respondents changed. A shift towards long-term pandemic management issues was observed. Respondents reported to experience more fears concerning the pandemic in general, as well as economic and healthcare crises. Medical professionals reported higher level of fear of the pandemic than other groups included in this study. This study uses before-and-after approach which highlights the changes in people's knowledge and perception of the COVID-19 pandemic during the pandemic's progression.
