Background: Data on how the coronavirus disease 2019 (COVID-19) affected consultations in ophthalmic departments are sparse.

Objectives: To examine the epidemiology of ophthalmic consultations in a large pediatric emergency medicine department (PED) during the first nationwide COVID-19 lockdown in Israel.

Methods: The database of a tertiary pediatric medical center was retrospectively reviewed for patients aged < 18 years who attended the PED from 17 March to 30 April 2020 (first COVID-19 lockdown) and the corresponding period in 2019. Background, clinical, and disease-related data were collected from the medical charts and compared between groups.

Results: The study included 757 PED visits. There were no significant differences in demographics between the groups. The 2020 period was characterized by a decrease in PED visits (by 52%), increase in arrivals during late afternoon and evening (P = 0.013), decrease in visits of older children (age 5–10 year), and proportional increase in younger children (age 1–5 years) (P = 0.011). The most common diagnoses overall and during each period was trauma followed by conjunctivitis and eyelid inflammation. The mechanisms of trauma differed (P = 0.002), with an increase in sharp trauma and decrease in blunt trauma in 2020 (P < 0.001 for both). In 2020, 95% of traumatic events occurred in the home compared to 54% in 2019 (P < 0.001).

Conclusions: Parents need to learn appropriate preventive and treatment measures to prevent serious and long-term ophthalmic injury while minimizing their exposure to the COVID-19. PEDs and ophthalmic pediatric clinics should consider increasing use of telemedicine and the availability of more senior physicians as consultants during such times.

Background: Human milk produced during prolonged lactation (> 1 year) is extraordinarily rich in fat and has a higher energy content than human milk produced during short lactation.

Objectives: To estimate the fatty acid (FA) profile of human milk and to test the hypothesis that the proportion of C12 and C14 (two dietary saturated FA known to most promote hypercholesterolemia) in human milk during prolonged lactation is similar to that in short lactation.

Methods: We conducted a cross-sectional study of 30 mothers of term infants lactating for more than 1 year as compared with 25 mothers of full-term infants who lactated for 2–6 months. Milk was collected by manual expression in mid-breastfeeding.

Results: The two groups did not differ in maternal height, weight, body mass index, diet, infant birth weight and gestational age, but mothers in the prolonged lactation group were significantly older. There was a significant correlation between lactation duration and C12 or C14. The percentage of all FA combined (except for C12 and C14) decreased significantly over time. In contrast, C12:0 and C14:0 combined increased significantly during lactation (R2 = 10.0%, P < 0.03).

Conclusions: Women who lactated for more than 1 year had higher C12 and C14 FA percentages in their milk than women who lactated for 2–6 months.

Objective: To establish population-based standards of birth weight of singletons in Israel.

Methods: Data on birth weight and gestational age were obtained from the registries of the Israel Ministry of Health and Ministry of the Interior. During the 8 year study period there were 1,074,122 infants delivered in Israel; 787,710 (73%) were included in this analysis.

Results: In this study we provide data of birth weight by gestational age of live infants born in Israel between 1993 and 2001. Ranges of birth weight by gestational age are also depicted for singleton and multiple pregnancies. Fetuses in multiple pregnancies grow in a similar manner to singletons until 30 weeks of gestation, after which their growth slows down.

Conclusions: Use of these data as a standard for “intrauterine” growth better represents the Israeli neonatal population than the American standards. In addition, curves of multiple pregnancies are significantly different from those of singleton pregnancies and might be more appropriate in these pregnancies.

Background: Increased serum potassium and intraventricular hemorrhage occur frequently in preterm infants.

Objective: To retrospectively analyze data obtained on infants with severe IVH[1] in relation to blood K⁺ concentrations.

Methods: We identified all patients with severe IVH born between July 1997 and July 2000. Each patient was pair-matched with a control infant of the same gestational age (±1 week) without IVH in terms of head ultrasound findings on day 5, and whole blood K⁺ on days 3–5.

Results: There were 24 infants in each group. The IVH group had significantly lower 1 minute Apgar scores and pH and higher blood K⁺ than the control group. Blood pH and K⁺ were inversely correlated. Stepwise regression analysis, taking into account blood pH and 1 minute Apgar score, showed a correlation only between blood K⁺ and IVH status.

Conclusions: Severe IVH is significantly associated with higher blood K⁺ concentrations. A causal relationship cannot be ascertained at this point.

Methods: We compared the cost of treating anemia of prematurity in two consecutive 12-month periods: before and after the introduction of EPO therapy in our unit. The cost of blood bank charges as well as disposable items and the cost of EPO were compared.

Results: A significantly smaller number of infants required blood transfusions in the EPO group (2 of 25 vs. 9/21 before EPO was introduced). The cost of therapy for anemia of prematurity was significantly smaller in the EPO group (128±168 US$ per infant vs. 151±189 US$ per infant before the introduction of EPO).

Conclusion: We conclude that EPO is an efficient and cost-effective alternative to blood transfusions in VLBW infants.
