PURPOSE: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. MATERIALS AND METHODS: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (> or =3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. RESULTS: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was 10.7degrees, 13.8degrees, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. CONCLUSION: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.

PURPOSE: To evaluate the optical quality after laser in situ keratomileusis (LASIK) or serial photorefractive keratectomy (PRK) using a double-pass system and to follow the recovery of optical quality after laser vision correction. METHODS: This study measured the visual acuity, manifest refraction and optical quality before and one day, one week, one month, and three months after laser vision correction. Optical quality parameters including the modulation transfer function, Strehl ratio and intraocular scattering were evaluated with a double-pass system. RESULTS: This study included 51 eyes that underwent LASIK and 57 that underwent PRK. The optical quality three months post-surgery did not differ significantly between these laser vision correction techniques. Furthermore, the preoperative and postoperative optical quality did not differ significantly in either group. Optical quality recovered within one week after LASIK but took between one and three months to recover after PRK. The optical quality of patients in the PRK group seemed to recover slightly more slowly than their uncorrected distance visual acuity. CONCLUSIONS: Optical quality recovers to the preoperative level after laser vision correction, so laser vision correction is efficacious for correcting myopia. The double-pass system is a useful tool for clinical assessment of optical quality.

A 50-year-old female was referred to our clinic with visual disturbance, hyphema and increased intraocular pressure (IOP) in her right eye 7 days after experiencing blunt trauma in that eye. She had undergone uncomplicated laser in situ keratomileusis (LASIK) on both eyes 10 years earlier. At initial examination, the best corrected visual acuity (BCVA) in her right eye was counting fingers at 2 feet with no correction. Central Goldmann applanation tonometry (GAT) showed an IOP of 7 mm Hg. Peripheral digital tonometry showed the IOPs in her right eye superiorly, nasally, temporally, and inferiorly were 36 mm Hg, 35 mm Hg, 34.5 mm Hg and 36.5 mm Hg, respectively. Slit-lamp examination showed diffuse epithelial and stromal edema and a blood clot 1 mm in height in the anterior chamber. Spectral domain scanning laser ophthalmoscope/optical coherence tomography (SD-SLO/OCT) images showed a pocket of fluid between the LASIK flap and the underlying stroma. The patient was started on anti-inflammatory agent and IOP lowering agents. After 15 days of treatment, IOP measured with GAT was 10 mm Hg, slit-lamp examination showed that epithelial and stromal edema had disappeared, and OCT showed no fluid between the corneal flap and stroma.

PURPOSE: To develop a novel, simplified method for correcting the ischemic index of nonperfused areas in diabetic retinopathy (DR). METHODS: We performed a retrospective review of 103 eyes with naive DR that underwent ultra-widefield angiography (UWFA) over a year. UWFAs were graded according to the quantity of retinal non-perfusion, and uncorrected ischemic index (UII) and corrected ischemic index (CII) were calculated using a simplified, novel method. RESULTS: The average differences between UII and CII in the non-proliferative DR group and the proliferative DR group were 0.7 +/- 0.9% in the <25% CII group, 3.0 +/- 0.9% in the 25% to 49.9% CII group, and 3.6 +/- 0.6% in the >50% CII group, respectively. A CII >25% was critical for determining DR progression (p < 0.001). CONCLUSIONS: Distortion created by UWFA needs to be corrected because the difference between UII and CII in DR increases with the ischemic index.

Glioblastoma multiforme (GBM) is a brain tumor notorious for its malignancy. The key reason for the limited efficacy of standard treatment is the high recurrence rate of GBM, even after surgical resection. Hence, intensive postsurgical chemical therapies, such as the systemic delivery of various drugs and/ or drug combinations, are typically followed after surgery. However, overcoming the blood-brain barrier by systemic administration to efficiently deliver drugs to the brain tumor remains a daunting goal. Therefore, various local drug delivery methods showing potential for improved therapeutic efficacy have been proposed. In particular, the recent application of electronic devices for the controlled delivery of chemotherapy drugs to GBM tissue has attracted attention. We herein review the recent progress of local drug delivery strategies, including electronics-assisted strategies, at the research and commercial level. We also present a brief discussion of the unsolved challenges and future research direction of localized chemotherapy methods for GBM.

Systemic sclerosis (SSc) is a generalized connective tissue disorder of unknown etiology. Clinically, there is a broad spectrum of disease ranging from widespread severe skin thickening to skin thickening limited to the distal extremities. In rare cases of systemic sclerosis, no cutaneous change only with internal organ involvement has been reported, which is called ?ystemic sclerosis sine scleroderma (ssSSc)?. We describe a patient with Raynaud? phenomenon, who showed intestinal pseudoobstruction as a presenting symptom but did not show any skin change. She had also an esophageal motility disorder, but other organ involvement was not evident. Antinuclear antibody was positive. Her obstruction symptoms were improved by decompression by nasogastric tube and pharmaceutical treatment with erythromycin and octreotide.

OBJECTIVE: We investigated plantar nerve injuries associated with calcaneal fracture and severity of disability. METHOD: From July, 2001 to June, 2002, twelve patients who had calcaneal fractures with persistent foot pain and paresthesia were included in our study. We examined electromyography for medial and lateral plantar nerve, inferior calcaneal nerve, also evaluated types of calcaneal fracture and severity of pain and disability with nerve injury. RESULTS: The intraarticular types were 13 cases, extraarticular type was 1 case and communited types were 2 cases. In the electromyographic findings, the 9 cases were diagnosed asneuropathy. In a cases with neuropathy, 8 persons complained over moderate degree of pain and all persons complained over moderate degree of walking disability. However one of three persons without neuropathy complained over moderate degree of walking disability. So disability tended to be more severe in cases with neuropathy. CONCLUSION: We think that neuropathy associated with calcaneal fracture is a cause of aggravation of pain and walking disability, and electromyography for nerves of foot will be needed in the calcaneal fracture.

OBJECTIVE: To evaluate the correlation of electrodiagnostic severity, severity of symptom, and clinical severity in carpal tunnel syndrome (CTS). METHOD: The sixty eight patients with documented CTS in outpatient clinic from January, 2000 to June, 2001 were included (9 male, 59 female, averaged age 50.0+/-8.8 years). We evaluated the severity of symptom, functional status of ADL with the Levine' questionnaire, and clinical severity with 3 kinds of examination (thenar atrophy, sensory change, and Phalen's test). The electrodiagnostic severity was classified according to Stevens' classification and compared with the severity of symptom, functional status, and clinical severity. RESULTS: The electrodiagnostic severity was classified into three degrees. Five patients (7.4%) were classified into mild degree, 32 patients (47.1%) moderate degree, 31 patients (45.6%) severe degree. The average of severity of symptom scores were 28.4+/-8.5, 31.8+/-7.4, and 31.8+/-9.1 respectively, and there was no significant difference (p>0.05) between the groups. Functional status scales were 14.2+/-6.7, 15.6+/-5.4 and 18.9+/-7.0 respectively and no significant difference (p=0.07) but there was a tendency that the severer was electrodiagnostic severity, the more decreased functional status scale. The clinical severity showed a significant correlation with the electrodiagnostic severity (p<0.05). CONCLUSION: The electrodiagnostic severity has a significant correlation with the clinical severity, but not with the severity of symptom, the functional status in CTS.
