ABSTRACT
PURPOSE: To assess the comorbidity of dry eye syndrome (DES) and changes in corneal curvature in children with allergies. MATERIALS AND METHODS: This prospective, comparative, and observational interventional study included 49 patients, who presented to the Ophthalmology Clinic of a State Hospital in Turkey. There were 25 patients with clinically diagnosed seasonal allergic conjunctivitis (AC) (with complaints of itching and papilla formation of conjunctiva; AC group) and 24 healthy children (control group). There with no significant differences in age between groups. Using the ocular surface disease index (OSDI) questionnaire, we performed tear film break-up time (BUT), central reflex tear meniscus height (TMH-R) measurement, Schirmer test on both groups and evaluated keratometry (K1, K2) and spherical equivalent (SE). RESULTS: Patients ranged in age from 6 to 18 years (median age, 11.79 years; 46.9% male; 53.1% female). The papillary reaction was severe in 10% of patients with AC. The prevalence of dry eye in children with AC was 12%. There was no statistically significant difference between groups for K1, K2, and SE (P > 0.05, all comparisons). BUT was statistically different (P = 0.004) between groups, indicating that a higher OSDI the tear film BUT was lower (ρ = 0.567). Statistically, significant negative moderate correlations were found between papillary reaction and the Schirmer test, BUT, and TMH-R (ρ = 0.454, -0.412, -0.419, and P = 0.001, 0.003, 0.002, respectively). CONCLUSIONS: The evaluation of pediatric patients with AC requires further attention to ensure an adequate diagnosis of DES.

Valproic acid (VPA) may affect thyroid hormone profile, causing alteration in serum trace elements concentrations. The aim of this study was to prospectively investigate this relationship in children receiving VPA monotherapy for a period up to 6 months. Serum thyrotropin (TSH), free thyroxine (FT4), free triiodothyronine (FT3), thyroxine (T4), triiodothyronine (T3), thyroglobuline (TG), selenium (Se), zinc (Zn), and copper (Cu) levels were evaluated at baseline and at the 6th month in all the patients and in the control group. The mean Cu concentration in the 6th months of VPA therapy was significantly lower than that of the control group. TSH level was significantly increased in the patient group whereas FT4 was significantly decreased. The mean TSH level in the 6th month of VPA therapy was significantly higher than that of the control group, whereas mean T4 level was significantly lower. The Cu level in the 6th months of VPA therapy was positively correlated with T4 level. ΔlogCu and ΔTSH were negatively correlated. This study suggests that the alteration in the serum thyroid hormone profile during VPA therapy may result from the reduction in serum Cu levels.

Several case reports have presented various neurological complications caused by lightning. However, there was no report related to cerebral salt wasting caused by lightning injury. We described a patient with lightning strike, who was subsequently diagnosed with cerebral salt wasting.
