Purpose: To report a rare case of giant pleomorphic adenoma of the lacrimal gland involving the palpebral lobe causing severe mechanical ptosis and visual field defect, which was removed successfully. Case Summary: An 82-year-old man visited our clinic with a large protruding mass on his left upper lid that had grown for approximately 10 years causing severe ptosis. Preoperative orbital CT showed a 2.3 × 2.0 cm sized large mass which was suspicious of hemangioma. The mass was completely excised through a lid crease incision. The histopathologic examination showed typical findings of pleomorphic adenoma. After the surgery, preoperative mechanical ptosis was completely resolved and during the 6 months of follow-up, there was no abnormality of tear secretion and evidence of tumor recurrence. Conclusions: The authors experienced a rare case of giant pleomorphic adenoma of the lacrimal gland involving the palpebral lobe and resolved mechanical ptosis by complete removal of the tumor through a lid crease incision.

Purpose: To evaluate the long-term prognosis and complications of laser epithelial keratomileusis (LASEK). Methods: A retrospective study including 92 eyes of 46 myopic patients treated with LASEK from November 1999 to February 2003 was performed. Follow-up visits were at 3 months, 6 months, 1 year, and 8 years. Treated eyes were divided into 2 groups according to preoperative spherical equivalent (SE) : low and medium myopia (<-6.0 D), and high myopia (>-6.0 D). The main outcome measures were UCVA, BCVA, postoperative SE, efficacy index, safety index, predictability, and postoperative complications. Results: Preoperative visual acuity was 1.24 ± 0.42 log MAR, and the average of SE was -5.28 ± 1.63 D. Postoperative visual acuity log MAR was significantly improved compared to preoperative visual acuity, and the average of visual acuity was 0.12 ± 0.13 log MAR. The percentage of eyes within ± 1.0 D of emmetropia 8 years after having LASEK was 69.5% in the mild and moderate myopia group, and 63.6% in the high myopia group. There was no significant difference of safety index, efficacy index or complications between the 2 groups at 1 month, 3 months, 1 year, and 8 years. Safety index was maintained over 0.9 and efficacy index was larger than 0.8. There were no other complications during the observation period. Conclusions: An 8-year follow-up showed LASEK for mild to moderate and high myopia to be a safe and effective procedure. J Korean Ophthalmol Soc 2012;53(10):1438-1444

Background : Monoplegia is the paralysis of a limb. It is commonly caused by an injury to the cerebral cortex, and rarely caused by injury to the internal capsule, brain stem, or spinal cord. Most problems with cerebral cortex is derived from the occlusion of a brain cortex blood vessel due to thrombus or embolus. Objectives : This study is to see if there is a significance in thermal differences of acupoints in diagnosis and treatment of monoplegia on an upper extremity to test the validity of acupuncture and herbal treatment for it. Methods : By using Digital Infrared Thermographic Imaging(DITI), thermal differences$({\Delta}T)$ of acupoints on the upper extremity in a patient with monoplegia on the right upper extremity were measured after an attack of the disease. By giving Mangeum-tang(萬金湯) and treating the patient with acupuncture. the temperature changes of the upper extremity were examined through DITI and improvement was observed. Results : Compared with the left arm which suffered no such injury, the right recovered about 80% of sensation, and the grade of monoplegia improved from Grade O to Grade V. Also, the temperatures of right palmar-dorsal hand and the region of Weiguan(外關, Waiguan, TE5) were $1^{\circ}C$ and $1.45^{\circ}C$ higher than the same left region on admission day, but the thermal differences$({\Delta}T)$ narrowed to $0.5^{\circ}C$ by the last day. Conclusions : Results suggest that DITI screening is a reliable method of prognosis and that the time required for treatment can be estimated through this method in cases of monoplegia to an upper extremity. Also, progress in treatment is reflected in thermal differences of acupoints of the monoplegic upper extremity in accordance with the theory of meridian. This supports a role for acupuncture and herbal treatment for monoplegia.

An urban road collapse has become one of the significant geohazards frequently occurring in metropolitan cities worldwide. In most cases, these devastating superficial collapses are known to be induced by small underground cavities. They are created by the failure of subsurface structures and pipelines (e.g., water supply/sewer lines, subway tunnels). However, the cavity generation and expansion process, interacted by intense precipitation, groundwater movement, and subsurface geologic environment, is not yet fully understood. This study aims to understand the mechanism of cavity initiation and expansion using a numerical model coupling groundwater flow, poroelastic deformation, and internal soil erosion. The model is then applied to road collapse cases by a damaged sewer line failure and internal erosion. Effects of the precipitation rate and period on internal erosion are also investigated to predict potential risks for road collapse. Numerical simulation results show that the underground cavities are closely related to the focused groundwater flow by the leakage through an opening in the damaged pipeline. Internal erosion accelerates the removal of fine soil particles and creates collapsing-susceptible vacant areas. The results also show that intense precipitation in a short interval exerts the most damaging effects on the subsurface stability comparing other scenarios with less severe and continuous rainfalls.
