Background
To investigate the effect of the bridge-in, objective, preassessment, participatory learning, post assessment, and summary (BOPPPS) model combined with case-based learning (CBL) on ophthalmology teaching for five-year paediatric undergraduates.
Methods
The effects of the BOPPPS model combined with CBL (BOPPPS-CBL) and traditional lecture-based learning (LBL) on ophthalmology teaching were compared among students in a five-year programme. The questionnaire surveys of the students were collected and statistically analysed after the class. The final examination scores, including on elementary knowledge and case analysis, in the two groups were analysed.
Results
There were no statistically significant differences between the teachers and students in the baseline data. More students agreed that the BOPPPS-CBL model helped develop their problem-solving skills, analytical skills and motivation for learning better than the LBL model. There was no significant difference in learning pressure between the two groups. The final examination scores of the BOPPPS-CBL group were significantly higher than those of the LBL group. The overall course satisfaction of the BOPPPS-CBL group was obviously higher than that of the LBL group.
Conclusions
The BOPPPS-CBL model is an effective ophthalmology teaching method for five-year paediatric undergraduates.
Background
Thygeson’s superficial punctate keratitis (TSPK) is reportedly a rare disease with an insidious onset, numerous remissions and exacerbations, and a long duration. The corneal lesions are elevated, whitish–grey in colour, and granular in the intraepithelium. A few reported cases of TSPK exist, and paediatric experience is limited. Due to the unknown aetiology and controversial treatment strategies for TSPK, we performed a literature review to summarize the criteria for the diagnosis, treatment and prognosis of TSPK to provide a basis for the treatment of TSPK in paediatric patients.
Case presentation
The clinical course of a boy with TSPK who repeatedly presented with episodes of tearing, photophobia and foreign body sensation in both eyes is described. Irritation was uncontrollable with antiviral and antibiotic medications, and it was managed by corticosteroids. No recurrence was reported at the 1-year follow-up after corticosteroid replacement and tapering.
Conclusions
The clinical features, treatment and prognosis between adult and paediatric TSPK patients have many similarities. The diagnosis of TSPK in children is more difficult, leading to missed diagnosis. TSPK needs to be carefully differentiated from other types of keratitis, especially intraepithelial secondary and other infectious ocular surface diseases.
Background: Seasonal allergic conjunctivitis (SAC) and perennial allergic conjunctivitis (PAC) were the most usual types of allergic conjunctivitis. House dust mites were the most common sensitization agents for SAC and PAC. This study aimed to explore SAC and PAC risk factors in children. Methods:We recruited 176 children suffering from SAC or PAC and 131 control subjects in southwest China. A questionnaire was provided to all the subjects’ parents. Several eye exams were performed, and all the subjects received the skin prick test (SPT). We analyzed the questionnaire data, the scores of the symptoms/signs and the SPT results. Results: The percentage of children that had ever been breastfed in the case group was lower than in the control group (P<0.05). The rate of parental allergy history in the case group was higher than for the control group (P<0.01). Compared with the control group, the case group was more likely to have other systemic allergic diseases (P<0.01). Some children in case group had adenoidal hypertrophy (ATH), and incidence rate was different from control group (P<0.05). The ocular symptoms and signs scores had significant correlation to the clinical course (P<0.05), but there was no correlation to the SPT results (P>0.05). Conclusion: Allergic conjunctivitis may coexist with a variety of allergic diseases, and SAC and PAC may be a risk factor for ATH. Breastfeeding should be recommended, as it may be an alleviating factor for allergic diseases, especially for children of parents with a history of allergic diseases. The disease severity is closely related to its course. Therefore, to avoid difficulty in treatment caused by the aggravation of symptoms and signs, timely antiallergic treatment was recommended.
