Purpose:
We report a case of central retinal artery occlusion after filler injection for upper lid retraction. Diagnosis and treatment were performed to recover visual acuity and good results.Case summary: A 40-year-old woman presented to our clinic with upper lid retraction. She was diagnosed with hyperthyroidism and thyroid orbitopathy. She had been examined regularly at a local clinic since 2016. At the first visit, her visual acuity was 1.0/1.0 and the intraocular pressure was 19 mmHg, with no unusual findings in the anterior segment. Hyaluronic acid filler was injected into the medial part of the left upper lid. As soon as the needle was removed, she complained of blurry vision and visual impairment. This was followed by the development of a relative afferent pupillary defect; her visual acuity was hand motion at 30 cm. After 5 minutes, we performed wide fundus imaging and optical coherence tomography, which revealed retinal artery occlusion and a cherry-red spot, along with inner retina hyperreflectivity. Under a diagnosis of central retinal artery occlusion, we performed anterior chamber paracentesis, intravenous mannitol and acetazole injection, and an ocular massage. Approximately 1.5 hours after filler injection, retinal artery reperfusion and loss of the cherry red spot were observed and, after about 3 hours, her vision had recovered to 1.0 from hand motion at 30 cm.
Conclusions
Central retinal artery occlusion after filler injection, when diagnosed promptly, can be treated by anterior chamber paracentesis, intravenous mannitol and acetazole injection, and ocular massage.
2.Peripapillary and Macular Microvasculature of the Retina in Primary Angle Closure Suspect
Journal of the Korean Ophthalmological Society 2025;66(1):45-54
Purpose:
To compare the macular and peripapillary vascular parameters between the primary angle closure suspect (PACS) eyes and normal control eyes using optical coherence tomography angiography (OCTA).
Methods:
In this retrospective study, 42 PACS subjects and 38 normal individuals are included. Vessel density (VD) and perfusion density (PD) of the macular area and peripapillary area, and fovea avascular zone parameter were analyzed using OCTA and compared between two groups after adjustment for the axial length.
Results:
There were no statistically significant differences in sex ratio, age, refractive errors and intraocular pressures between both groups. In the peripapillary area, inferior VD and PD in the outer zone were significantly lower in the PACS eyes, while the retinal nerve fiber layer thicknesses were similar between groups (p = 0.032, 0.026). In the macular superficial capillary plexus, inferior VD and PD in the inner zone, inferior VD and PD, nasal VD and PD in the outer zone were significantly lower in the PACS eyes, whereas ganglion cell inner plexiform layer thickness were similar between both groups (all p < 0.005).
Conclusions
The VDs and PDs of retinal capillaries in PACS eyes, which have no glaucomatous changes in the retinal nerve fiber layer and optic nerve disc, were significantly lower compared to normal eyes.

The purpose of this study was to evaluate a rotational stability of endodontic electronic motors by comparing the changes of rotational speed, depending on the number of usages and with/without static load. Twelve new endodontic electronic motors were used in this study. Non contact type digital tachometer was used for measuring the rotational speed of handpiece. True RMS Multimeter was used for measuring the voltages and the electric currents. All measurements were recorded every 10 seconds during 10 minutes and repeated 9 times. Five repetition was done per each electronic motor. To statistical analysis, student t-test, repeated measures and Scheffe's post-hoc tests were performed. In the same motor group, there was no significant difference in all measurements. In all groups, there was no significant difference in the amount of rotational speed changes depending on the number of usages and with/without static load. In the limitation of this study, the results showed that all kinds of endodontic electronic motors in this study had an established rotational stability. Therefore they could be safely used in root canal treatment with a reliable maintenance of rotational speed, regardless of the number of usages and with/without load.

PURPOSE: This study was conducted to identify the spiritual well-being and spiritual care of hospice team members. METHOD: Between December 2005 and February 2006, a questionnaire was given to 192 hospice team members. The instruments used in this study were the Spiritual Well-Being Scale(SWBS) developed by Paloutzian, & Ellison(1984), and a Spiritual Care Performance Scale developed by the authors. RESULTS: The levels of spiritual well-being were relatively high: significantly lower in the 25-29 years old, in the unmarried, and in the 1-2 million won income groups, and significantly higher in Protestants, Catholics, clergy, and volunteers. The levels of performance of spiritual care were intermediate; significantly higher in clergy, and those with 10 or more years of experience. There was a positive correlation between: levels of spiritual well-being and age; levels of spiritual well-being and performance of spiritual care; and levels of performance of spiritual care and age. The factors affecting the levels of spiritual well-being included religion, age, and performance of spiritual care. The factors affecting the levels of performance of spiritual care were the years of hospice experience and spiritual well-being. CONCLUSION: Because there was a positive correlation between levels of spiritual well-being and performance of spiritual care, there is a need to develop a strategies to increase the spiritual well-being of hospice team members.

Korean Journal of Ophthalmology 2022;36(2):154-158
Purpose:
This study aims to report the efficacy and safety of one-snip punctoplasty and 18-gauge irrigation technique in patients with primary canaliculitis.
Methods:
All patients diagnosed with primary canaliculitis between January 2020 and August 2021 at Inje University Busan Paik Hospital are included. All patients underwent one-snip punctoplasty and 18-gauge irrigation technique. After the procedure, patients had topical antibiotics. The resolution of symptoms and inflammatory signs and complications were evaluated 3 weeks after the procedure.
Results:
A total of 11 patients (eight female patients and three male patients, 14 canaliculi) aged 34 to 82 years with a mean age of 63.8 ± 15.7 years were participated. Common symptoms were epiphora, mucopurulent discharge, and injection, and common signs were discharge from punctum, pouting punctum, punctal erythema, and swellling. Among 14 canaliculi, 12 (85.7%) had complete resolution and two underwent second treatment which showed completed resolution after the treatment.
Conclusions
One-snip punctoplasty and 18-gauge irrigation technique are minimally invasive to punctum and canaliculi and are a highly effective surgical procedure for patients with primary canaliculitis.

PURPOSE: In this study, we investigated the effect of silk scaffolds on one-wall periodontal intrabony defects. We conjugated nano-hydroxyapatite (nHA) onto a silk scaffold and then seeded periodontal ligament cells (PDLCs) or dental pulp cells (DPCs) onto the scaffold. METHODS: Five dogs were used in this study. Bilateral 4 mmx2 mm (depthxmesiodistal width), one-wall intrabony periodontal defects were surgically created on the distal side of the mandibular second premolar and the mesial side of the mandibular fourth premolar. In each dog, four of the defects were separately and randomly assigned to the following groups: the PDLC-cultured scaffold transplantation group (PDLC group), the DPC-cultured scaffold transplantation group (DPC group), the normal saline-soaked scaffold transplantation group, and the control group. The animals were euthanized following an 8-week healing interval for clinical, scanning electron microscopy (SEM), and histologic evaluations. RESULTS: There was no sign of inflammation or other clinical signs of postoperative complications. The examination of cell-seeded constructs by SEM provided visual confirmation of the favorable characteristics of nHA-coated silk scaffolds for tissue engineering. The scaffolds exhibited a firm connective porous structure in cross section, and after PDLCs and DPCs were seeded onto the scaffolds and cultured for 3 weeks, the attachment of well-spread cells and the formation of extracellular matrix (ECM) were observed. The histologic analysis revealed that a well-maintained grafted volume was present at all experimental sites for 8 weeks. Small amounts of inflammatory cells were seen within the scaffolds. The PDLC and DPC groups did not have remarkably different histologic appearances. CONCLUSIONS: These observations indicate that nHA-coated silk scaffolds can be considered to be potentially useful biomaterials for periodontal regeneration.

Malignant rhabdoid tumor was first discovered in the kidney, and rhabdoid tumor of the lung was first reported in 1995. These were included as the variants of large-cell carcinoma, according to the 1999 World Health Organization classification of lung tumors. The rhabdoid tumor of the lung exhibits aggressive biological behavior and has a poor prognosis, and only a few reports of this tumor exist. We report a case of lung carcinoma with a rhabdoid phenotype, initially misdiagnosed as an aspergilloma, in a 48-year-old man who presented with recurrent hemoptysis. The chest computed tomography scans showed a huge consolidative lesion with an air crescent sign in the left upper lung and no contrast-enhancing lesion. An aspergilloma was diagnosed by the radiologist. However, after surgical excision and pathological examination, rhabdoid carcinoma was diagnosed. A surgical resection helps to make it possible to pathologically distinguish a malignancy from an aspergilloma.
