ABSTRACT
Purpose@#We assessed the clinical manifestations and prognostic factors associated with ocular infection in patients diagnosed with orbital and preseptal cellulitis. @*Methods@#We enrolled 40 patients diagnosed with ocular infection accompanied by orbital and preseptal cellulitis between October 2015 and December 2021. We divided patients into the “treatment success group” (patients whose infection resolved) and the “treatment failure group” (patients whose infection worsened and required evisceration). Clinical characteristics, such as infection-related ocular findings and microbiological features, were analyzed retrospectively in both groups. Chi-square tests and logistic regression analyses were performed to identify prognostic factors associated with treatment failure. @*Results@#The mean age of patients was 72.8 ± 11.92 years, with 17 (42.5%) of them being male. Among the patients, 11 had bacterial infections, and 3 had fungal infections. In total, 6 (15%) and 34 (85%) patients were classified into the treatment success and failure groups, respectively. The chi-square test revealed a significant association between the treatment failure group and several clinical factors, such as low best corrected visual acuity (BCVA), the logarithm of the minimum angle resolution (logMAR) BCVA > 2, low intraocular pressure (IOP) 2, IOP < 5 mmHg, large size of the corneal lesion, and a prolonged duration of symptoms demonstrated significant association with treatment failure. Notably, hypopyon is an important prognostic factor for treatment failure.
ABSTRACT
Purpose@#Liver grafts from donors with HBV infection contributed to expanding the donor pool under the hepatitis B immunoglobulin and antiviral agents (nucleos(t)ide analogues) in the HBV-endemic area. We report long-term outcomes of liver transplantations (LTs) using grafts from donors with active or chronic HBV infection. @*Methods@#Overall, 2,260 LTs performed in 3 major hospitals in Seoul from January 2000 to April 2019 were assessed for inclusion. Twenty-six grafts (1.2%) were obtained from HBsAg (+), HBeAb (+), or HBcAb (+) donors, and recipient outcomes were retrospectively reviewed. Donor and recipient demographics and transplantation outcomes were analyzed. @*Results@#Sixteen deceased donor LTs were performed using active HBsAg (+) grafts. Ten other LTs were sourced from 10 living donors. There was no significant difference in survival in patients who received deceased donor LTs compared with that in those who underwent LT with non–hepatitis virus-infected grafts. Fourteen patients who were followed up for >5 years were stable, and no difference in hepatocellular carcinoma recurrence rate was observed 5 years after transplantation between transplants from donors with and those without HBV. @*Conclusion@#Considering long-term outcomes, liver grafts from donors with active HBV replication can be safely used for LT.
ABSTRACT
To investigate differences of tear neuromediators between subjects with and without dry eye (DE) depending on the ocular sensitivity. Thirty-one subjects with DE and 29 subjects without DE were recruited in this study. The eyes were stimulated by exposure to an irritating product applied to the periocular region. Both DE and non-DE subjects were divided into the high sensitivity and low sensitivity groups based on the degree of ocular sensitivity to ocular irritation. Baseline tear film break-up time (TBUT) and corneal staining score were examined, and tear samples were collected. The concentrations of the tear neuromediators, including nerve growth factor (NGF), serotonin, calcitonin gene-related peptide (CGRP), substance P, neuropeptide Y, and vasoactive intestinal peptide were measured using the enzyme-linked immune sorbent assay. The baseline neuromediator concentrations were compared between subjects with and without DE based on ocular sensitivity. In both DE and non-DE subjects, baseline TBUT was significantly lower in the high sensitivity group than in the low sensitivity group. In the high sensitivity group, baseline tear NGF levels were higher in subjects with DE than in those without DE. In the low sensitivity group, baseline levels of tear CGRP were lower in subjects with DE than in those without DE. Tear neuromediators associated with DE had differences in their concentrations depending on ocular sensitivity. In patients with DE, tear NGF levels increased with high ocular sensitivity to ocular irritation, whereas tear CGRP levels decreased with low ocular sensitivity.
ABSTRACT
Purpose@#We evaluated the clinical manifestations of, and risk factors for, infectious keratitis in patients with ocular graft-versus-host disease (GVHD). @*Methods@#A total of 11 patients who developed infectious keratitis after a diagnosis of ocular GVHD between January 2015 and December 2020, and 36 who did not (the control group), were included in this retrospective study. We recorded sex, age, any underlying disease, any other organ affected by systemic GVHD, systemic immunosuppressant use, follow-up duration, clinical manifestations, the severity of ocular GVHD prior to infection, the size of the epithelial defect, the depth of infiltration, hypopyon status, and the results of microbiological tests. Systemic and ocular indices (including systemic GVHD status) were compared using the chi-squared test. Risk factors for infection were identified. @*Results@#Of the corneal indices, the presence of corneal filaments, the extent of corneal neovascularization, and the number of corneal epithelial defects were significantly higher in the infected group (p = 0.023, p = 0.004, and p = 0.001, respectively). GVHD severity was also significantly higher in that group (p < 0.001). The presence of corneal filaments, corneal neovascularization, and corneal epithelial defects prior to infection correlated significantly with the risk of infection (p = 0.046, p = 0.010, and p = 0.003, respectively). Multivariate analysis identified corneal epithelial defects as a significant risk factor for infection (p = 0.029). @*Conclusions@#In patients with ocular GVHD, corneal epithelial defects, corneal neovascularization, and corneal filaments prior to infection were associated with the development of infection. In particular, corneal epithelial defects before infection was a significant risk factor for infection.
ABSTRACT
Purpose@#To evaluate the clinical efficacy of amniotic membrane extract eye drops (AMEEDs) in patients with persistent epithelial defects (PEDs) of the cornea. @*Methods@#Sixteen patients with PEDs refractory to the conventional treatment were further treated with AMEEDs six times a day. Visual acuity, visual analog scale (VAS), esthesiometer score, and areas of the epithelial defects before and after 1 and 2 months of treatment were evaluated. After 2 months, AMEEDs were considered effective if all epithelial defects were healed, partially effective if the epithelial defects decreased in size compared with the baseline, and ineffective if the epithelial defects increased in size and required additional treatment. @*Results@#After 2 months of treatment with AMEEDs, there was a reduction in the area of epithelial defects (5.2 ± 3.1 mm2 vs. 0.1 ± 0.1 mm2, respectively, p = 0.01), as well as a significant improvement in best-corrected visual acuity (0.8 ± 0.5 logarithm of minimal angle of resolution [LogMAR] vs. 0.6 ± 0.3 LogMAR, respectively, p = 0.03), and VAS scores (4.3 ± 1.0 vs. 2.8 ± 0.7, respectively, p = 0.04) compared with the baseline values. Treatment with AMEEDs was effective in 13 (81.3%) patients and partially effective in three (18.8%) patients. @*Conclusions@#AMEEDs could stimulate epithelial wound healing and improve ocular symptoms in patients with refractory PED. Therefore, AMEEDs could be considered an effective treatment option for refractory PEDs.
ABSTRACT
Purpose@#To investigate the efficacy of intense pulsed light (IPL) treatment in patients with meibomian gland dysfunction (MGD) associated with Sjögren’s syndrome. @*Methods@#This study included 43 patients with MGD and Sjögren’s syndrome. Patients received either IPL with meibomian gland expression (IPL/MGX) (n = 22) or MGX only (n = 21). Treatments were administered three times at a 3-week interval. Patients were followed up 6 weeks after the end of the treatment. Ocular Surface Disease Index (OSDI), tear film breakup time with fluorescein dye (FBUT), non-invasive tear breakup time, tear meniscus height (TMH), Schirmer test, SICCA ocular surface staining score, meibum quality score (MQS), and meibum expression score (MES) were evaluated at each visit. Meibomian gland dropouts (meiboscore) and tear film lipid layer grade were measured using keratography. @*Results@#OSDI, FBUT, corneal surface staining score, MQS, meiboscore, and tear film lipid layer grade improved after IPL/MGX treatment (p < 0.05). In both treatment groups, MES significantly improved (p < 0.01 and p < 0.05 for IPL/MGX and MGX groups, respectively). The Schirmer test score, conjunctival surface staining score, and TMH after treatment were not significantly different between the groups. After treatment, the IPL/MGX group had significantly lower OSDI, FBUT, corneal staining score, MQS, and MES, but higher FBUT, compared with the MGX group (p < 0.05). @*Conclusions@#IPL treatment effectively improved tear film, ocular surface parameters, meibomian gland function, and lipid layer grade in patients with Sjögren’s syndrome and MGD.
ABSTRACT
Background/Aims@#Subepithelial tumors (SETs) are small, mostly asymptomatic lesions with normal overlying mucosa, usually identified incidentally on endoscopy. The aim of this study was to evaluate the pathologic diagnosis of SETs, and to assess the diagnostic yield and impact of endoscopic submucosal dissection (ESD) biopsy on the management of patients with SETs. @*Materials and Methods@#We included 52 subepithelial lesions in this study during the study period. Inclusion criteria included size of the SET >2 cm, and a gastrointestinal stromal tumor (GIST) that cannot be excluded using EUS. We performed an endoscopic biopsy of each SET using the ESD technique. @*Results@#The mean diameter of the lesions was 24.15±6.0 mm. The diagnostic yield of this method was 96.15%. Among the 52 participants, 45 were located in the stomach, four in the esophagus, and three in the duodenum. The pathologic diagnoses included: 17 leiomyomas, 13 GISTs, 11 ectopic pancreases, two carcinomas, two inflammatory fibroid polyps, two Brunner’s gland hyperplasia, two lipomas, one glomus tumor, and two remained undiagnosed. The mean duration of the procedure was 13.44±2.41 minutes. Three complications were associated with the procedure. @*Conclusions@#Deep biopsy via ESD is useful in determining the histopathologic nature of SETs. This method minimizes the need for unnecessary surgery in benign SETs.
ABSTRACT
Purpose@#To evaluate the clinical efficacy of preservative-free 0.15% sodium hyaluronate eye drops on the ocular surface after upper eyelid surgery. @*Methods@#This study included 43 patients who underwent upper eyelid surgery between December 2018 and May 2019. Patients were randomly assigned to group A (those treated with preservative-free 0.15% sodium hyaluronate eye drops) and group B (the control group). Ocular surface disease index score (OSDI), tear break up time (TBUT), Schirmer’s test, corneal staining score (CSS), meibomian gland (MG) quality, MG expressibility, and meiboscore were evaluated before surgery and at 1 week, 1 month, and 2 months after surgery. @*Results@#In group A, OSDI and TBUT showed a significant increase at 1 week after surgery compared with baseline values (all p < 0.05). In group B, OSDI, TBUT, and CSS were significantly higher at 1 week and 1 month after surgery (all p < 0.05), whereas there were no significant changes at 2 months after surgery compared with baseline values. At 1 month after surgery, OSDI (p = 0.03) and CSS (p < 0.01) showed significant changes between group A and group B; however, there was no significant change in the TBUT. There were no significant within-group differences in Schirmer’s test values, MG quality, MG expressibility, or meiboscore, and there were no significant between-group differences over time. @*Conclusions@#Preservative-free 0.15% sodium hyaluronate eye drops were shown to be an effective treatment for early dry-eye symptoms and ocular surface damage after upper eyelid surgery.
ABSTRACT
Purpose@#We report a case of infectious keratitis caused by Eikenella corrodens in a patient who lost visual function.Case summary: A 65-year-old male with histories of a corneal ulcer, glaucoma, and bullous keratopathy visited our hospital complaining of redness and pain in his right eye for the past 10 days. Slit-lamp examination revealed stromal infiltration, a 2-mm-high hypopyon, and severe inflammation of the anterior chamber. Vitreous opacity was evident on ocular ultrasonography. Culture of corneal scrapings yielded Eikenella corrodens. After 5 days of antibiotic treatment, ceftazidime was injected intravitreally and histoacryl glue applied to treat the corneal perforation and the endophthalmitis. Two months later, the eye was not inflamed. @*Conclusions@#Eikenella corrodens should be considered a possible pathogen when a patient with an underlying ocular disease presents with infectious keratitis. A corneal ulcer caused by Eikenella corrodens has not previously been reported in the Republic of Korea.
ABSTRACT
Purpose@#To analyze the clinical manifestations of culture-proven infective keratitis patients over a recent 10-year period. @*Methods@#We retrospectively reviewed the medical records of 956 cases of infective keratitis between January 2008 and December 2017 at eight tertiary hospitals. The study was performed to analyze the risk factors, causative microbial organisms, therapeutic outcomes, and prognosis. @*Results@#The most common risk factor of keratitis was trauma (33.2%). Initial visual acuity (V/A) was finger count or less in 449 eyes (47.0%). The common location of keratitis was central, and the size was 4 mm2 or less. Hypopyon was observed in 295 eyes (30.9%). Of the 1,039 cultured isolates, 443 (42.6%) grew Gram-negative bacteria with the most common being Pseudomonas aeruginosa. The most prevalent Gram-positive bacteria was Staphylococcus epidermidis, and fungi was Fusarium species. Surgical treatments were performed in 201 eyes (21.0%), followed by amniotic membrane transplantation (66 eyes) and evisceration (44 eyes). Final V/A was 20/100 or more in 422 eyes (44.1%). Gram-positive organisms were highly susceptible to moxifloxacin and vancomycin, and Gram-negative organisms were highly susceptible to levofloxacin and ceftazidime. An increase in resistance to these antibiotics was detected for Enterococcus and Pseudomonas. @*Conclusions@#In South Korea, infective keratitis occurs frequently in eyes with trauma. Staphylococcus epidermidis, Pseudomonas aeruginosa, and Fusarium species are commonly identified etiologies of microbial keratitis. The appropriate administered medical and surgical treatments of suspected infectious keratitis can lead to visual improvement with particular care taken to minimize infection related to resistant bacteria and fungal microbes as needed. An initial V/A of 0.02 or less, the presence of hypopyon, age of 65 years or more, and a central lesion were associated with poor clinical outcome of bacterial keratitis. Age of 70 years or more was a significant risk factor for poor clinical outcome of fungal keratitis.
ABSTRACT
Purpose@#We evaluated the clinical manifestations and risk factors of fungal keratitis after penetrating keratoplasty (PKP). @*Methods@#Eighteen patients who experienced fungal keratitis after PKP between January 2005 and January 2020 were included in this retrospective study. Clinical characteristics including sex, age, underlying disease, indication for PKP, symptom duration, visual acuity, graft state before infection, suture-related problems, size of epithelial defect, depth of infiltration, presence of hypopyon, use of eyedrops before infection, and the results of microbiological tests were analyzed. Patients were classified into the treatment success or failure group, and the risk factors were evaluated accordingly. @*Results@#The mean age at diagnosis was 63.94 ± 15.53 years. Fungal infection occurred a mean of 55.31 ± 44.72 months after PKP. The mean symptom duration was 10.33 ± 7.36 days. Of the 18 patients, 5 (27.8%) and 13 (72.2%) were in the treatment success and failure groups, respectively. Of the treatment failure group, seven patients (38.9%) underwent surgical management. The graft state before infection, symptom duration, and size of epithelial defects had significant correlations with treatment failure (all p < 0.05). Multivariate analysis identified graft state (p = 0.046) as a significant risk factor for treatment failure. @*Conclusions@#Graft state before infection, symptom duration, and size of epithelial defects were associated with the prognosis of fungal keratitis after PKP. Graft state before infection was a significant risk factor for treatment failure.
ABSTRACT
Background@#Mastectomy leaves unsightly scarring, which can be distressing to patients. Laser therapy for scar prevention has been consistently emphasized in recent studies showing that several types of lasers, including fractional ablation lasers, are effective for reducing scar formation. Nonetheless, there are few studies evaluating the therapeutic efficacy of ablative CO2 fractional lasers (ACFLs). @*Methods@#This study had a randomized, comparative, prospective, split-scar design with blinded evaluation of mastectomy scars. Fifteen patients with mastectomy scars were treated using an ACFL. Half of each scar was randomized to “A,” while the other side was allocated to group “B.” Laser treatment was conducted randomly. Scars were assessed using digital photographs of the scar and Vancouver scar scale (VSS) scores. Histological assessments were also done. @*Results@#The mean VSS scores were 2.20±1.28 for the treatment side and 2.96±1.40 for the control side. There was a significant difference in the VSS score between the treatment side and the control side (P=0.002). The mean visual analog scale (VAS) scores were 4.13±1.36 for the treatment side and 4.67±1.53 for the control side. There was a significant difference in VAS score between the treatment side and the control side (P=0.02). @*Conclusions@#This study demonstrated that early scar treatment using an ACFL significantly improved the clinical results of the treatment compared to the untreated scar, and this difference was associated with patient satisfaction.

ABSTRACT
Background/Aims@#To date, studies on various noninvasive techniques have been suggested to evaluate the degree of liver fibrosis. We aimed to investigate the diagnostic performance of se-rum asialo α1-acid glycoprotein (AsAGP) in the diagnosis of liver cirrhosis compared with chronic hepatitis for clinically useful result. @*Methods@#We conducted a case-control study of 96 patients with chronic liver disease. Chronic hepatitis was defined as the presence of chronic liver disease on ultrasonography, with a liver stiffness of less than 5.0 kPa as shown on magnetic resonance elastography (MRE). Liver cirrho-sis was defined as liver stiffness of more than 5.0 kPa on MRE. The serum AsAGP concentration was compared between the two groups. @*Results@#Serum AsAGP levels were significantly higher in patients with cirrhosis than in those with chronic hepatitis (1.83 μg/mL vs 1.42 μg/mL, p<0.001). Additionally, when comparing pa-tients in each cirrhotic group (Child-Pugh grades A, B, and C) to those with chronic hepatitis, AsAGP levels were significantly higher in all the cirrhotic groups (p<0.05, p<0.01, p<0.001, respectively). The sensitivity and specificity of AsAGP for detecting cirrhosis were 79.2% and 64.6%, respectively, and the area under the curve value was 0.733. The best diagnostic cutoff to predict cirrhosis was 1.4 μg/mL. AsAGP and bilirubin were found to be independent risk factors for the prediction of cirrhosis in the logistic regression analysis. @*Conclusions@#Serum AsAGP showed an acceptable diagnostic performance in predicting liver cirrhosis.

ABSTRACT
Cutaneous squamous cell carcinoma (cSCC) is the second most common nonmelanoma skin cancer, and its incidence is increasing globally. In Korea, there were 12,516 diagnosed cases of cSCC between 1999 and 2014. Surgical treatment, for which several options are available, is the standard of care for cSCC and securing a sufficient surgical resection margin is always important. cSCC of the scalp sometimes exhibits unusually aggressive behavior. In this article, we report a case of cSCC of the scalp with invasion into the skull and dura mater.
