ABSTRACT

PURPOSE: Previous studies have reported that action observation training has beneficial effects on enhancing the motor task, such as balance and gait functions. On the other hand, there have been few studies combined with action observation training and auditory feedback. The purpose of this study was to determine the effects of action observation training with auditory feedback on the gait function in stroke patients with hemiparesis. METHODS: A total of 24 inpatients with post-stroke hemiparesis were assigned randomly to either an experimental group 1 (EG 1, n=8), experiment group 2 (EG 2, n=8), control group (CG, n=8, EG 1). The EG 2 and CG watched video clip demonstrating three functional walking tasks with auditory feedback, without auditory feedback, and showing a landscape image, respectively. The exercise program consisted of 30 minutes, five times a week, for four weeks. The participants were measured to 10MWT (10 m walk test), 6MWT (6 minutes walking distance test), TUG (timed up and go test), DGI (dynamic gait index), time and steps of F8WT (figure-of-8 walk test). RESULTS: In the intra-group comparison after the intervention, EG 1 and EG 2 showed a significantly different gait function (10MWT, 6MWT, DGI, TUG, F8WT) (p < 0.05). In the inter-group comparison after intervention, EG 1 showed significant improvements in the entire gait parameters and EG 2 only showed significant improvement in DGI and TUG compared to CG (p < 0.05). CONCLUSION: These findings show that action observation training with auditory feedback may be used beneficially for improving the gait function of stroke patients with hemiparesis.

ABSTRACT

PURPOSE: To evaluate the long-term visual outcomes and complications of cataract surgery in eyes previously treated for retinoblastoma. METHODS: We reviewed the medical records of patients who underwent cataract extraction and intraocular lens implantation at Seoul National University Children's Hospital for a secondary cataract that developed after retinoblastoma treatment. RESULTS: During the period between 1990 and 2014, 208 eyes of 147 patients received eye-salvaging treatment (radiotherapy, chemotherapy, and local therapy) for retinoblastoma at Seoul National University Children's Hospital. Among these eyes, a secondary cataract was detected in 17 eyes of 14 patients, and five eyes of five patients underwent cataract surgery. The median age of cataract formation was 97 months (range, 38 to 153 months). The medial interval between the diagnosis of retinoblastoma and cataract formation was 79 months (range, 29 to 140 months). All patients received posterior chamber intraocular lens insertion after irrigation and aspiration of the lens through a scleral tunnel incision. Anterior vitrectomy and posterior capsulotomy were performed in two eyes and a laser capsulotomy was subsequently performed in one eye. No intraoperative and postoperative complications occurred. The median follow-up after surgery was 36 months (range, 14 to 47 months). The final best corrected visual acuities were improved in all five eyes. No intraocular tumor recurrences or metastases occurred. CONCLUSIONS: After retinoblastoma regression, cataract extraction in our series was not associated with tumor recurrence or metastasis. Visual improvement was noted in every patient.

ABSTRACT

PURPOSE: To evaluate the transcription pattern of Nod-like receptors (NLRs), the intracellular sensors, to detect danger signals in murine eyes with experimental autoimmune uveitis (EAU). METHODS: EAU was induced in B6 (C57BL/6) mice by subcutaneous injection of human interphotoreceptor retinoid binding protein and intraperitoneal injection of pertussis toxin. At 1, 2, and 3 weeks post-immunization, the eyeballs were extracted and subjected to histological and molecular assays using real-time reverse transcription polymerase chain reaction. RESULTS: The levels of nucleotide-binding oligomerization domain, Leucine rich Repeat and Pyrin domain 1 (NLRP1), NLRP3, nucleotide-binding oligomerization domain-containing protein 1 (NOD1), and NOD2 transcripts were increased at 2 weeks and gradually reduced thereafter. Notably, NLRP3 showed the highest expression in the eyes with EAU. Similarly, the transcript level of pro-inflammatory cytokine, interleukin-1beta, increased and reached a peak at 2 weeks post-immunization. The retinal structure was severely damaged by inflammation at 3 weeks post-immunization. CONCLUSIONS: Among NLRs, NLRP3 may induce inflammation in eyes after EAU immunization.

ABSTRACT

T-condylar fracture is a type of distal humerus fracture. T-condylar fracture in children is rare, with reported incidence of less than 1% of T-condylar fractures. The mean reported age of T-condylar fracture in children is 11. Cases in children under 5 years-old are extremely rare. Herein, we report on a T-condylar fracture of the distal humerus in a 5-year-old boy. This patient was treated with open reduction and K-wire fixation through the posterolateral approach. The result of treatment was satisfactory; therefore, we report this case.

ABSTRACT

The objective of the present study was to establish the method of measurement of hydrogen peroxide and to estimate the anti-oxidative effect of genistein in the skin. UVB induced skin oxidation and anti-oxidative effect of genistein formulations were evaluated by determining levels of hydrogen peroxide. The mechanism involved in the determination of hydrogen peroxide is based on a color reaction between ferric ion (Fe3+) and xylenol orange, often called FOX assay and subsequent monitoring of absorbance values of the reactant at 540 nm. The reaction was to some extent pH-dependent and detection sensitivity was greatest at pH 1.75. Genistein liposomal gel demonstrated better anti-oxidative effect with regard to lowering hydrogen peroxide levels elevated by UVB irradiation compared to genistein-suspended gel. A linear relationship has been observed between anti-oxidative effect of genistein and drug deposition in the skin tissue. Genistein liposomal gel resulting in the localization of the drug in the deeper skin led to improved anti-oxidative effect compared to genistein gel. The suggested method for evaluation of oxidation of the skin can be used as a tool to screen effective anti-oxidative agents and their delivery systems acting on the skin.
