Purpose:
To define and evaluate the short-term clinical outcomes of the four-flanged technique for scleral fixation of a dislocated four-eyelet intraocular lens (IOL).
Methods:
Eleven eyes of 11 patients who underwent scleral fixation of dislocated four-eyelet intraocular lenses using a four-flanged technique were studied retrospectively. We measured the best-corrected visual acuity (BCVA), corneal endothelial cell density, intraocular pressure (IOP), spherical equivalent, astigmatism, IOL tilt and decentration, and postoperative complications.
Results:
The BCVA was 0.25 ± 0.11 logarithm of the minimal angle of resolution (logMAR) before surgery and 0.14 ± 0.12 logMAR 6 months later (p < 0.001). The corneal endothelial cell count was 2,427 ± 384 and 2,367 ± 298/mm2 before and after surgery, respectively (p = 0.285). The spherical equivalent was 6.02 ± 4.90 and 0.11 ± 0.36 before and after surgery, respectively. There was no significant difference in astigmatism before and after surgery. The mean IOL tilt and decentration were 2.44 ± 1.68° and 0.23 ± 0.09 mm, respectively. The refractive difference was 0.11 ± 0.24 diopters (D). Postoperative complications occurred in one eye; one flange lay outside the scleral tunnel, triggering hyperemia and conjunctival inflammation.
Conclusions
The four-flanged scleral fixation technique for a dislocated four-eyelet IOL improved the BCVA but did not significantly affect corneal endothelial cell loss. The procedure significantly reduced postoperative IOL tilt, decentration, and astigmatism, and may be a useful alternative to scleral fixation of a dislocated four-eyelet IOL.

Avulsion injury of the flexor digitorum profundus tendon from distal phalanx is considered as a rare injury. Accrording to the classification by Leddy and Pacter, this case is Type III, which is a large bony fragment retained by the tendon. The distal pulley prevents retraction beyond the middle phalanx. We are reporting a case with brief review of literatures.

3.Relationship of between Task Performance, Job Satisfaction, and Organizational Contribution of Dental Hygienists.
Journal of Dental Hygiene Science 2016;16(4):302-309
This study aimed to evaluate the relationship between task performance, job satisfaction, and organizational contribution of dental hygienists, and to analyze the resulting impact on the organizational contribution of the dental hygienists. The study sample included 300 people working in a dental clinic during May 2016; data were collected through a self-questionnaire and an online questionnaire. Subsequently, 285 responses were analyzed. The results showed that a higher monthly income, business support services, and work satisfaction affect organizational contribution. The correlation of organizational contribution was the highest with business management in task performance and with work satisfaction in job satisfaction. In conclusion, a dental hygienist, who may have highest careers and is involved in the management of dental work, affects the organizational contribution of the dental clinic.

PURPOSE: The purpose of this study was to evaluate the usefulness of diffusion-weighted imaging (DWI) for the differential diagnosis of various intracranial cystic lesions. MATERIALS AND METHODS: This study included 19 patients (13 males, 6 females) with a mean age of 42.5 years. The final histopathological diagnoses for 14 patients were pyogenic brain abscess (n=3), glioblastoma (n=3), ependymoma (n=1), anaplastic astrocytoma (n=1), pilocytic astrocytoma (n=1), hemangioblastoma (n=2), arachnoid cyst (n=1), epidermoid (n=1) and schwannoma (n=1). The other cases of metastasis (n=4) and arachnoid cyst (n=2) were diagnosed on the basis of clinical, laboratory and imaging data. DWI imaging studies were performed with a 1.5 T MR system. A single shot spin echo EPI pulse sequence was applied. B values were set at 0 and 1000 sec/mm2. The apparent diffusion coefficient (ADC) were calculated from the ADC map of 10 different cystic brain lesions. Conventional MR imaging included T2WI, T1WI, FLAIR and contrast enhanced T1WI. We analyzed the location, nature, signal intensity on DWI, and the enhancement pattern of the lesions. RESULTS: All of the 3 cases of brain abscess, 1 of 4 cases of metastasis and 1 case of epidermoid showed hyperintensity on DWI. The mean ADC value of brain abscess (2 cases) was less than 1.15 (0.13x10-3 mm2/s). The mean ADC values of the other cystic lesions (8 cases) were variable, ranging from 2.840.66 to 3.100.16 (10-3 mm2/sec). CONCLUSION: DWI and ADC values were useful in the differential diagnosis of various intracranial cystic lesions, but some metastatic tumors may mimic a brain abscess on DWI. Therefore, a clinical correlation is mandatory.

5.Health States of Residents near by US Military Camps.
Korean Journal of Aerospace and Environmental Medicine 2004;14(4):126-134
This study was conducted to evaluate the relation between health states of residents near by US military camps and noise caused by their aircrafts, in the cities of Chuncheon, Gunsan, and Daegue. From November 2001 to July 2002, we surveyed 426 residents for psychosocial well-being states, psychiatric problems, infertility and sleep disorders by questionnaire, and applied pure-tone audiometry to 83 residents for measuring hearing abilities at qualified medical institutes. The residents near by military camps were more suffered from psychosocial and psychiatric problems, infertility, and sleep disorders than residents of the control areas. In the aspects of psychiatric problems, residents living within 50m from the military camp boundaries had 5.42 times higher risk and those living at the outward had 3.57 times higher than the control residents. And nearby residents had more decreased hearing abilities than the control residents by over 10dB in whole frequencies, statistically confirmed by mixed model with age adjustment. The residents near by US military camps were suffered from psychosocial and psychiatric problems, infertility, sleep disorders and hearing disturbances, induced by noise of US military aircrafts.

6.Acute Embolic Attack on Persistent Sciatic Artery: 1 case.

Journal of the Korean Society for Vascular Surgery 2004;20(2):268-271
Persistent sciatic artery (PSA) is a continuation of the internal iliac artery into the popliteal-tibial vessels and this structure provides the major blood supply to the lower limb bud during early embyrologic development, Its remnants participate in the formation of the inferior gluteal, deep femoral, popliteal, peroneal and pedal vessels. When the femoral artery develops, the PSA then involutes. In rare circumstances it persists and so provides the only major blood supply to the lower limb. The PSA was first reported by Green in 1832 and until now, only about 100 cases have been reported in the world literatures. This rare vascular anomaly is associated with aneurysmal formation in 15% to 46% of cases and it has a bilateral location in 22% of PSA cases. In more than 40% of cases, PSA is asymptomatic. When present, such non-specific symptoms as gluteal pain and painful buttock mass are presented. However, the most frequent clinical finding is lower limb ischemia because in 25% of such cases, the presented symptoms are limb threatening. We describe here the case of a 54 year-old female affected with PSA occlusion, and she was treated with a combination of thrombolysis and thromboembolectomy.

7.Alitretinoin-induced Pseudotumor Cerebri: A Case Report
Journal of the Korean Ophthalmological Society 2024;65(9):644-649
Purpose:
We present a case of alitretinoin-induced pseudotumor cerebri.Case summary: A 28-year-old woman presented with a 1-month history of bilateral papilledema and intermittent blurred vision in the left eye. She had been taking alitretinoin (9-cis-retinoic acid, AlitocⓇ; GlaxoSmithKline) for atopic dermatitis and hand eczema. Although visual acuity remained intact in both eyes, mild central scotoma was detected bilaterally. Optical coherence tomography revealed increased retinal nerve fiber layer thickness in both eyes. Enhanced magnetic resonance imaging revealed no abnormalities except for bilateral flattening of the posterior sclera. Cerebrospinal fluid exhibited an elevated opening pressure (220 mmH2O) and a normal composition. Following the discontinuation of alitretinoin, the intermittent blurred vision, papilledema, and central scotoma improved significantly within 2 months.
Conclusions
Alitretinoin use should be monitored carefully for a potential development of pseudotumor cerebri, particularly in patients with pre-existing risk factors.mmH2O) and a normal composition. Following
