Purpose:
To analyze the effect of office-based probing in different age groups of children with congenital nasolacrimal duct obstruction.
Methods:
A retrospective study was conducted in 146 children (200 eyes) diagnosed with congenital nasolacrimal duct obstruction who underwent office-based probing. The children were classified into four groups at the time of probing: group A (< 6 months), group B (> 6 months but < 12 months), group C (> 12 months but < 20 months), and group D (> 20 months but < 48 months). Age at the time of the procedure, gender, laterality, follow-up period, clinical symptoms, and the number of probings were investigated. Success rates were compared among the four groups in terms of sex, age, laterality, and the number of probings.
Results:
The success rate of the first probing was 160/200 eyes (80.0%). The success rates were 87.5% in group A, 85.7% in group B, 77.6% in group C, and 76.7% in group D. No significant difference in the success rate was observed according to age (p = 0.550). The second probing was performed in 40 eyes. The success rates were 100% in group A, 87.5% in group B, 70.6% in group C, and 35.7% in group D. A significant difference in the success rate was observed according to age (p = 0.048). The success rate of the second probing was 25/40 eyes (62.5%). No significant difference in laterality was observed among the four groups (p = 0.291).
Conclusions
No significant difference in the success rate of first nasolacrimal duct probing was detected, but a significant difference in the success rate of the second probing was detected according to age in children < 4 years of age.

PURPOSE: The roles of gut microbiota on the natural course of atopic dermatitis (AD) are not yet fully understood. We investigated whether the composition and function of gut microbiota and short-chain fatty acids (SCFAs) at 6 months of age could affect the natural course of AD up to 24 months in early childhood.METHODS: Fecal samples from 132 infants were analyzed using pyrosequencing, including 84 healthy controls, 22 transient AD and 26 persistent AD subjects from the Cohort for Childhood Origin of Asthma and Allergic Diseases (COCOA) birth cohort. The functional profile of the gut microbiome was analyzed by whole-metagenome sequencing. SCFAs were measured using gas chromatography-mass spectrometry.RESULTS: Low levels of Streptococcus and high amounts of Akkermansia were evident in transient AD cases, and low Clostridium, Akkermansia and high Streptococcus were found in children with persistent AD. The relative abundance of Streptococcus positively correlated with scoring of AD (SCORAD) score, whereas that of Clostridium negatively correlated with SCORAD score. The persistent AD group showed decreased gut microbial functional genes related to oxidative phosphorylation compared with healthy controls. Butyrate and valerate levels were lower in transient AD infants compared with healthy and persistent AD infants.CONCLUSIONS: Compositions, functions and metabolites of the early gut microbiome are related to natural courses of AD in infants.

Purpose:
We report bilateral central retinal vein occlusion in a patient with Takayasu arteritis.Case summary: A 52-year-old female with hypertension complained of decreased vision in both eyes. The best-corrected visual acuities (BCVAs) were 0.2 in the right eye and 0.15 in the left eye. Fundus examination and optical coherence tomography revealed dilated and tortuous retinal veins, many flame-shaped hemorrhages, and macular edema in both eyes. We diagnosed central retinal vein occlusion in both eyes. Neck ultrasonography and computed tomography/angiography revealed Takayasu arteritis with near-total occlusion of the left common carotid artery, external carotid artery, and subclavian artery. We prescribed oral azathioprine and three monthly intravitreal injections of bevacizumab (Avastin®; Genentech, Inc., South San Francisco, CA, USA, 1.25 mg/0.05 mL). After 6 months of treatment, the retinal hemorrhage and macular edema disappeared and the BCVAs improved to 0.6 in the right and 0.8 in the left eye.
Conclusions
When encountering a case of bilateral central retinal vein occlusion, assessment of systemic vascular occlusive diseases such as Takayasu arteritis may be required.

PURPOSE: To report the surgical technique to remove a chestnut thorn through a corneal incision. CASE SUMMARY: A 54-year-old female visited our clinic complaining of a sudden foreign body sensation and conjunctival injection in her left eye after picking chestnuts 4 days prior to her visit. Visual acuity of both eyes was 1.0 and the intraocular pressures were within normal limits. Slit lamp examination revealed that a chestnut thorn had deeply penetrated the left corneal stroma and a small number of inflammatory cells were observed in the anterior chamber. There was no corneal defect stained with fluorescein and the Seidel test was negative. A corneal foreign body comprised of a chestnut thorn and its remnants was diagnosed and emergency surgery was performed. A partial corneal incision was made along the foreign body and the exposed foreign body was easily and completely removed. The patient was treated with topical antibiotics after surgery and no complication was observed during a follow-up period of 3 months. CONCLUSIONS: In the case of a corneal foreign body comprised of a chestnut thorn, the foreign body with its remnants were easily removed by performing a partial corneal incision.

BACKGROUND/AIMS: Guidelines recommend surveillance for hepatocellular carcinoma (HCC) recurrence at 3-month intervals during the first year after curative treatment and 6-month intervals thereafter in all patients. This strategy does not reflect individual risk of recurrence. We aimed to stratify risk of recurrence to optimize surveillance intervals 1 year after treatment. METHODS: We retrospectively analyzed 1,316 HCC patients treated with resection/radiofrequency ablation at Barcelona Clinic Liver Cancer stage 0/ A. In patients without 1-year recurrence under 3-monthly surveillance, a new model for recurrence was developed using backward elimination methods: training (n=582)/ validation cohorts (n=291). Overall survival (OS) according to risk stratified by the new model was compared according to surveillance intervals: 3-monthly versus 6-monthly (n=401) after lead time bias correction and propensity-score matching analyses. RESULTS: Among patients without 1-year recurrence, age and international normalized ratio values were significant factors for recurrence (hazard ratio [HR], 1.03; 95% confidence interval [CI], 1.00 to 1.03; p=0.009 and HR, 5.63; 95% CI, 2.24 to 14.18; p < 0.001; respectively). High-risk patients stratified by the new model showed significantly higher recurrence rates than low-risk patients in the validation cohort (HR, 1.73; 95% CI, 1.18 to 2.53; p=0.005). After propensity-score matching between the 3-monthly and 6-monthly surveillance groups, OS in high-risk patients under 3-monthly surveillance was significantly higher than that under 6-monthly surveillance (p=0.04); however, OS in low-risk patients under 3-monthly surveillance was not significantly different from that under 6-monthly surveillance (p=0.17). CONCLUSIONS: In high-risk patients, 3-monthly surveillance can prolong survival compared to 6-monthly surveillance. However, in low-risk patients, 3-monthly surveillance might not be beneficial for survival compared to 6-monthly surveillance.

PURPOSE: To report a delayed onset of multiple evanescent white dot syndrome in a patient with punctate inner choroidopathy. CASE SUMMARY: A 23-year-old female complained about sudden visual loss in the right eye. Best-corrected visual acuity (BCVA) was 20/100 in the right eye and 20/20 in the left eye. In fundus examination and optical coherence tomographic images, subfoveal choroidal neovascularization (CNV) with hemorrhage was observed in the right eye, accompanied by multiple lesions of atrophic pigmentation on the posterior pole in both eyes. We diagnosed the patient as punctate inner choroidopathy (PIC) and CNV in the right eye, and treated her using three monthly intravitreal injections of bevacizumab (Avastin®, Roche, Basel, Switzerland; 1.25 mg/0.05 mL). The CNV regressed and the BCVA improved to 20/20. Two years later, she complained of visual impairment in her left eye. The BCVA was 20/40. Fundus photography revealed numerous small white dots around the posterior pole and optic disc. Disruption of the photoreceptor layer was seen in optical coherence tomography images. Small white dots were observed as multiple hyperfluorescent dots in fluorescein angiography and hypofluorescent spots in indocyanine green angiography. An enlarged blind spot was observed in the visual field. We diagnosed her as multiple evanescent white dot syndrome (MEWDS). One month after systemic steroid treatment, the multiple white dots disappeared and the BCVA improved to 20/20. CONCLUSIONS: We determined that PIC and MEWDS, which belong to the white dot syndrome, could occur in a patient at different times.

PURPOSE: The optimal indications for omitting adjuvant radiation therapy (RT) after breast-conserving surgery are still controversial in ductal carcinoma in situ (DCIS) of the breast. The purpose of this study was to validate the role of postoperative RT in DCIS patients aged ≤50 years and with tumor margin widths of <1 cm, both of which have been proven to be high-risk features for recurrence in cohorts not receiving RT. METHODS: Using two multicenter retrospective studies on DCIS, a pooled analysis was performed among patients aged ≤50 years and with margin widths < 1 cm. All patients underwent breast-conserving surgery. Two hundred thirty-two patients received postoperative RT, while 54 did not. The median follow-up period was 77 months (range, 2–190 months) and 70 months (range, 5–166 months) in the patients who received RT and those who did not, respectively. RESULTS: The patients who received RT had larger tumors (p < 0.001), higher nuclear grade (p < 0.001), closer margin width (p < 0.001), and negative estrogen receptor expression (p=0.010) compared with those who did not receive RT. During the follow-up period, there were 17 ipsilateral breast tumor recurrences (IBTRs) as follows: invasive carcinoma in 10 patients and DCIS in seven. In the univariate analysis, the treatment with RT and human epidermal growth factor receptor 2 (HER2) status were significant risk factors for IBTR. The 7-year IBTR rates with and without postoperative RT were 3.6% and 13.1%, respectively (p=0.008). HER2-positive tumors had a higher IBTR rate than the HER2-negative tumors (7-year rate, 13.6% vs. 3.9%; p=0.003). CONCLUSION: Postoperative RT following breast-conserving surgery significantly reduced the 7-year IBTR rate in the DCIS patients aged ≤50 years and with margin widths < 1 cm. HER2 positivity was associated with increased IBTR in these patients.

PURPOSE: To report ocular findings of a mucolipidosis type II patient with novel mutation. CASE SUMMARY: A 10-year-old boy visited our pediatric genetic metabolic clinic for evaluation of his overall developmental delay and short stature. The boy was diagnosed with mucolipidosis type II (I-cell disease) using plasma enzyme assay and DNA sequencing of the GNPTAB gene mutation. An ophthalmologic investigation was then performed, and a depressed nasal bridge, broad nose, and swelling in the upper lid of both eyes were noted. The best corrected visual acuity was 0.32 and 0.1 and the intraocular pressure was 35 mmHg and 24 mmHg in the right and left eyes, respectively. The anterior chamber angles of both eyes were normal and mild cornea opacity in both eyes was observed. Fundus examination revealed retinal atrophy with folds in both eyes, as well as optic disc edema and optic atrophy in the right and left eyes, respectively. Atherosclerotic changes in the retinal vessels and cystoid macular edema in the left eye were observed, and ocular ultrasound revealed increased posterior sclera thickness in both eyes. CONCLUSIONS: Ocular manifestations of mucolipidosis type II are not currently well-known, and differentiation from other metabolic disorders may be difficult. An ophthalmic work-up can assist in diagnosis, and regular ophthalmic examinations should be used to maintain visual function in mucolipidosis patients.
