PURPOSE To explore the mechanism of action of topical lodoxamide and cromolyn sodium treatment in vernal keratoconjunctivitis (VKC) and to compare the efficacy of these drugs to each other. DESIGN Single-investigator, masked, randomized, clinical trial. PARTICIPANTS Twenty male and 10 female patients between the ages of 6 and 19 years, who were diagnosed as having active VKC, were enrolled in this study. INTERVENTIONS The patients were randomly divided into two equal groups (groups A and B). Group A patients received topical lodoxamide ophthalmic solution 0.1% (LOS); topical cromolyn sodium ophthalmic solution 4% (CSO) was prescribed to group B patients in a dose of two drops four times daily. MAIN OUTCOME MEASURES The eye symptom severity scores and clinical signs of the patients were evaluated both in the pre- and post-treatment periods. In addition to the clinical data, conjunctival impression cytologic specimens were obtained from patients both before and after treatment. Impression cytologic specimens were stained using immunohistochemical methods to detect the percentages of CD4(+), CD8(+), CD45RA(+), and CD23(+) cells. Statistical analyses were performed within and between groups. RESULTS The percentages of CD4(+) and CD23(+) cells in tear samples of patients in groups A and B were significantly higher in the pretreatment stage than post-treatment stage. In the post-treatment stage, group A patients had significantly lower CD4(+) and CD23(+) cell values compared with group B patients. Patient symptom scores and clinical signs were at a significantly lower level after treatment with either LOS or CSO in both groups A and B compared with their pretreatment values. Moreover, group A patients had significantly lower symptom scores and clinical signs than group B patients in the post-treatment stage. CONCLUSIONS Clinical superiority of LOS over CSO may be linked to its greater effect on the CD4(+) cells, because CD4(+) cells plays a pivotal role in the pathogenesis of VKC.

The case of a 63 year-old man with a giant scrotal and retroperitoneal tumor is herein reported. The initial symptoms began in the scrotum and subsequent abdominal distention resulted in discomfort 2 years later. The intraabdominal organs were under pressure because of the bulky mass, and the patient had dyspnea. Ultrasonograpy, computed tomography, and fine needle aspiration biopsy investigations all revealed a retroperitoneal tumor suspected to be liposarcoma. At operation, a tumor weighing 42 kg was excised. Respiratory support was provided in the early postoperative period. The histopathological diagnosis was myxoid liposarcoma. The patient was discharged from the hospital 14 days after the operation and was scheduled to undergo radiotherapy.

The aim of the present study was to evaluate the effect of phototherapy and oxidative stress on the growth plate of newborn rats. Forty newborn Sprague-Dawley rats were randomized into a phototherapy group and a control group. Twenty of the rats received phototherapy for 7 days. All zones of the growth plate were assessed with quantitative histomorphometric analysis. Individual zonal lengths were measured for the reserve zone (RZ), the proliferative zone (PZ), the hypertrophic zone (HZ), ossifying cartilage (OC), and total zone (TZ) of the growth plate. Levels of plasma malondialdehyde (MDA), an index of oxidative stress, were also evaluated. Compared with zonal lengths on day 7 after phototherapy between the two groups, the phototherapy group had significantly lower values than those of controls for RZ (5.13 ± 0.36 vs. 6.4 ± 0.85 mm × 10−2; P < 0.001), PZ (20.6 ± 3.0 vs. 29.25 ± 1.68 mm × 10−2; P < 0.001), HZ (15.4 ± 1.44 vs. 20.87 ± 1.12 mm × 10−2; P < 0.001), OC (47.08 ± 4.25 vs. 62.06 ± 3.7 mm × 10−2; P < 0.001), and TZ (88.15 ± 6.56 vs. 118.48 ± 4.50 mm × 10−2; P < 0.001). Plasma MDA levels were correlated with the size of the PZ in the phototherapy group (r = −0.53, P = 0.01). In a multivariate regression model for all rats, being in the phototherapy group was the best predictor of the size of the TZ (β = −0.94, P < 0.001), with the total variance explained being 88%. These results suggest that in newborn rats, receiving phototherapy is associated with early impairment of growth plate structure, and oxidative stress may be the main risk factor for growth plate injury.
