BACKGROUND/AIMS: Laparoscopic cholecystectomy is the standard treatment for acute cholecystitis. Percutaneous cholecystostomy is an alternative treatment to resolve acute inflammation in patients with severe comorbidities. The purpose of this study is to determine the optimal timing of laparoscopic cholecystectomy after percutaneous cholecystostomy for the patients with acute cholecystitis. METHODS: This retrospective study was conducted in patients who underwent cholecystectomy after percutaneous cholecystostomy from January 2010 through November 2014. Seventy-four patients were included in this study. The patients were divided into two groups by the operation timing. Group I patients underwent cholecystectomy within 10 days after percutaneous cholecystostomy (n=30) and group II patients underwent cholecystectomy at more than 10 days after percutaneous cholecystostomy (n=44). RESULTS: There was no significant difference between groups in conversion rate to open surgery, operation time, perioperative complications rate, and days of hospital stay after operation. However, complications related to cholecystostomy such as catheter dislodgement occurred significantly more often in group II than group I (group I:group II=0%:18.2%; p=0.013). CONCLUSIONS: Timing of laparoscopic cholecystectomy after percutaneous cholecystostomy did not influence postoperative outcomes. However, late surgery caused more complications related to cholecystostomy than early surgery. Therefore, early laparoscopic cholecystectomy should be considered over late surgery after percutaneous cholecystostomy insertion.

OBJECTIVES: To determine which factors are related to young adults perception of their health. Two research questions were asked. Which aspects of health does self-perceived health as a index of general health reflect? Why do two individuals with the same level of general health have different health perceptions? METHODS: The sampling frame comprised college or graduate school students, aged 20 to 29, who were members of A, one of the 4 biggest internet communication services. The questionnaires were sent to study samples(n= 1,000) and answered by E-mail. Response rate was 37.0%. RESULTS: Firstly, physical health ranked highest and self-perceived health ranked lowest. Secondly, health, anxiety, depression, and self-perceived health showed significant differences between the sexes, with women showing a higher health status in these categories except for self-perceived health. Thirdly, the two factors significantly related to self-perceived health were physical health and self-esteem, as determined by multivariate analysis. CONCLUSIONS: The factors significantly related to self-perceived health were physical health and self-esteem. Further studies of the health characteristics of young adults are needed.

Purpose: To evaluate the 1-year clinical outcome of subsequent trabeculectomy following 25-gauge transconjunctival sutureless vitrectomy in refractory glaucoma with vitreous filling of the anterior chamber. Methods: This study was a retrospective and consecutive case series study. We reviewed the medical records of pseudophakic and aphakic glaucoma patients with vitreous filling of the anterior chamber who underwent subsequent trabeculectomy with mitomycin C (MMC), following 25-gauge transconjunctival sutureless vitrectomy. All patients had been followed up for more than 12 months. Complete surgical success was defined as an intraocular pressure (IOP) ≤18 mmHg and IOP reduction ≥20% without glaucoma medication. Qualified surgical success was defined as IOP ≤18 mmHg and an IOP reduction ≥20% with or without glaucoma medication. Results: Eight eyes of seven patients (four eyes of four patients with pseudophakic glaucoma and four eyes of three patients with aphakic glaucoma) were included in this study. The cumulative probability of qualified success was 87.5%, and the cumulative probability of complete success was 62.5% at 12 months after trabeculectomy. The mean IOP decreased from 28.1 ± 3.5 mmHg preoperatively to 15.0 ± 3.7 mmHg at the final visit (p = 0.012). The mean number of glaucoma medications decreased from 4 ± 0 to 1.5 ± 2.1 at the final visit (p = 0.010). Complications including retinal detachment, vitreous hemorrhage, cystoid macular edema, and vitreous incarceration into the fistula were not observed. Conclusions Transconjunctival sutureless vitrectomy and subsequent trabeculectomy with MMC is an effective method for controlling IOP in pseudophakic and aphakic glaucoma with vitreous filling of the anterior chamber.

Primary intrapulmonary thymoma (PIT) is a very rare lesion of uncertain pathogenesis. PIT should be considered when the histopathological appearance of a lung tumor shows features that are uncommon but similar to those of a thymoma. In this case report, we discuss the case of a 59-year-old female with a solitary pulmonary nodule that was confirmed to be PIT on the basis of pathological tests. Treatment with complete resection showed good results.

PURPOSE: To evaluate the impact of LASIK on vision-related quality of life (QOL) in myopia patients METHODS: This study included 288 patients who received laser in situ keratomileusis (LASIK) between July and December 2001 from two eye clinics located in Seoul and Pusan. Myopia-specific Quality of Life Questionnaire (MQLQ) was developed. MQLQ contained 34 questions in 4 domains that assess the effect of LASIK on visual function, visual symptoms, social and role function, and psychological well-being. Baseline QOL for the condition that refractive error was corrected by glasses or contact lenses before undergoing LASIK were evaluated by means of self-administered questionnaire. The evaluation was repeated at 4 days, 1 month, 3 months, and 6 months after LASIK. All question items were rated on a scale ranging from 1 (maximal dysfuntion) to 5 (no dysfunction). RESULTS: Average score for the MQLQ changed from 3.20 preoperatively to 3.76, 3.99, 4.07, and 4.11 at 4 days, 1 month, 3 months, and 6 months after surgery, indicating a continuous improvement of overall QOL following LASIK. Among the 4 dimensions, social and role function showed the biggest improvement (changes in score: 1.48, p=0.001), followed by psychological well-being(0.98, p=0.001), visual function(0.67. p=0.001), and visual symptoms (0.49, p=0.001). CONCLUSIONS: LASIK has a significant contribution to improve QOL in myopia patients.

Headache is a frequent complaint in coronavirus disease-19 (COVID-19) patients. Nevertheless, no detailed information on the pathophysiology of headache in COVID-19 infection is currently limited. We encountered a patient developing headache, diplopia, and intracranial hypertension after COVID-19 infection. The patient no more complained of headache and diplopia after the intracranial pressure was normalized. Our case suggests that intracranial hypertension is a mechanism of headache in COVID-19 infection. We report herein a case of transient intracranial hypertension after COCVID-19 infection.

Purpose: We report bilateral, diffuse, uveal melanocytic proliferation caused by a stomach adenocarcinoma.Case summary: A 78-year-old male complained of visual impairment 3 months in duration. He had diabetes and had undergone cataract surgery on both eyes 4 years prior. His best-corrected visual acuity was counting fingers in the right eye and 20/160 in the left eye. Both intraocular pressures were normal. The anterior segments yielded no specific findings. The maculae exhibited multiple, round, patchy, pigmented or depigmented lesions with exudative retinal detachment. Fluorescein angiography revealed multiple hyperfluorescent lesions. Optical coherence tomography revealed that the hyper-reflective exudates lay between the neurosensory retina and the retinal pigment epithelium. We diagnosed bilateral, diffuse, uveal melanocytic proliferation and performed a systemic evaluation. Computed tomography revealed several mass lesions in the lung, stomach, and lymph nodes; these appeared to be malignant. An esophagogastroduodenoscopic biopsy confirmed that the lesions were adenocarcinomas. Conclusions A bilateral, diffuse, uveal melanocytic proliferation induced by a primary malignant tumor exhibited multiple, pigmented subretinal exudates associated with exudative macular retinal detachment. In patients with such findings, it is necessary to evaluate the malignant tumor status of remote organs.

This study investigated dexamethasone (DXM) residues in the milk from intramuscularly dosed dairy cows and established the withdrawal time (WT) of DXM in milk. Eighteen healthy Holstein cows were injected with 20 (DXM-1) or 40 mL (DXM-2) of a drug containing 1 mg/mL of DXM. After administering DXM, milk samples were collected from all cows at 12-hour intervals for five days. The DXM residue concentrations in milk were determined by liquid chromatography-mass spectrometry/mass spectrometry. The correlation coefficient of the calibration curve was 0.9966, and the limits of detection and quantification (LOQ) were 0.03 and 0.1 μg/kg, respectively. The recoveries were 97.0% to 104.0%, and the coefficient of variations was less than 7.22%. After treatment, DXM in DXM-1 was detected above the LOQ in two milk samples at 36 hours and below the LOQ in all milk samples of DXM-2 at 48 hours. Using the WT calculation program WT 1.4, the withdrawal periods of DXM-1 and DXM-2 in milk were established to be two days. In conclusion, the developed analytical method is sensitive and reliable for detecting DXM in milk. The estimated WT of DXM in bovine milk is shorter than the current milk WT recommendation of three days for DXM in lactating dairy cows.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, there was a shortage of medical resources and the need for proper treatment guidelines for brain tumor patients became more pressing. Thus, the Korean Society for Neuro-Oncology (KSNO), a multidisciplinary academic society, has undertaken efforts to develop a guideline that is tailored to the domestic situation and that can be used in similar crisis situations in the future. As part II of the guideline, this consensus survey is to suggest management options in specific clinical scenarios during the crisis period. Methods: The KSNO Guideline Working Group consisted of 22 multidisciplinary experts on neuro-oncology in Korea. In order to confirm a consensus reached by the experts, opinions on 5 specific clinical scenarios about the management of brain tumor patients during the crisis period were devised and asked. To build-up the consensus process, Delphi method was employed. Results: The summary of the final consensus from each scenario are as follows. For patients with newly diagnosed astrocytoma with isocitrate dehydrogenase (IDH)-mutant and oligodendroglioma with IDH-mutant/1p19q codeleted, observation was preferred for patients with low-risk, World Health Organization (WHO) grade 2, and Karnofsky Performance Scale (KPS) ≥60, while adjuvant radiotherapy alone was preferred for patients with high-risk, WHO grade 2, and KPS ≥60. For newly diagnosed patients with glioblastoma, the most preferred adjuvant treatment strategy after surgery was radiotherapy plus temozolomide except for patients aged ≥70 years with KPS of 60 and unmethylated MGMT promoters. In patients with symptomatic brain metastasis, the preferred treatment differed according to the number of brain metastasis and performance status. For patients with newly diagnosed atypical meningioma, adjuvant radiation was deferred in patients with older age, poor performance status, complete resection, or low mitotic count. Conclusion It is imperative that proper medical care for brain tumor patients be sustained and provided, even during the crisis period. The findings of this consensus survey will be a useful reference in determining appropriate treatment options for brain tumor patients in the specific clinical scenarios covered by the survey during the future crisis.
