PURPOSE: To report a case of corneal edema caused by an iatrogenic lidocaine injection into the corneal stroma created while performing a local anesthetic (lidocaine) injection into the eyelid for a blepharoplasty procedure. CASE SUMMARY: A 15-year-old female visited our clinic after the onset of severe pain and decreased visual acuity while receiving a local anesthetic injection in the upper blepharon for a blepharoplasty procedure. At the first clinical visit, visual acuity was hand motion and an accurate anterior chamber examination was difficult because of corneal edema. The Seidel test was negative. On corneal optical coherence tomography, the corneal thickness was 1,580 µm without any sign of Descemet's membrane detachment. We prescribed 5% NaCl four times a day and prednisolone acetate eight times a day. On the next day after injury, the corneal edema was significantly improved (central corneal thickness: 660 µm), and Descemet's membrane detachment was still not observed. One week after injury, the naïve visual acuity was 20/20, the central corneal thickness was 560 µm, and the endothelial cell count was 3,260 cells/cm². Three weeks after injury, the corneal edema was fully resolved and only slight temporal corneal haziness remained. After 2 months, the cornea was clear without any subjective discomfort. CONCLUSIONS: Corneal edema without Descemet's membrane detachment can be resolved spontaneously without aggressive treatment such as gas or air injection. However, endothelial cell count and corneal opacity need to be monitored on follow up exam. This clinical experience suggests that severe corneal edema in anterior stromal layer could be spontaneously resolved without severe complication.

Granulomatous(lobular) mastitis is a distinct disease entity of unknown etiology which is characterized by noncaseating granulomatous lobulocentric inflammation. We describe a rare case of granulomatous(lobular) mastitis of a 36 year-old pregnant woman a review of the literature. The mass which was discovered in the third month of her pregnancy, began as a localized, nontender mass on the left breast and persisted during her entire pregnancy. It decreased slightly in size when she began taking post-partum bromocriptine. Clinically and mammographically, the mass was highly suspected as a carcinoma with axillary lymph node metastasis. Fine needle aspiration smears revealed numerous aggregates of granulomas composed of epithelioid histiocytes admixed with multinucleated giant cells of Langhans' and foreign body type, and collections of polymorphonuclear leukocytes. Ziehl-Neelsen, silver methenamine and PAS stain were negative for acid-fast bacilli, fungus, and bacilli on the smear respectively. Histologically, granulomatous inflammation was centered on the breast lobules. Caseation necrosis was absent, instead, numerous microabscesses were formed in the center of the granulomas. Cultures of the fresh tissue for the AFB, aerobic and anaerobic bacteria, and fungus were all negative. Excision of the mass was performed without further treatment and there was no recurrence of the mass 6 months postoperatively. An autoimmune mechanism, infection, and some association with oral contraceptives have been suggested as etiologic factors in the literature.

Purpose: Children have few small alveoli, which reduce lung compliance; in contrast, their cartilaginous rib cage makes their chest wall highly compliant. This combination promotes lung collapse. Prolonged inspiratory to expiratory (I:E) ratio ventilation is used to optimize gas exchange and respiratory mechanics in surgery. However, the optimal ratio is unclear in children. We hypothesized that, compared to a 1:2 I:E ratio, a 1:1 I:E ratio would improve dynamic compliance and oxygenation, and affect the peak airway pressure in pediatric patients undergoing surgery. Materials and Methods: Forty-eight patients aged ≤6 years who were scheduled to undergo surgery under general anesthesia with an arterial line were randomly allocated to receive 1:1 (group 1:1) or 1:2 (group 1:2) I:E ratio ventilation. Airway pressure, respiratory system compliance, and arterial blood gas analyses were compared between groups immediately after induction (T0), 30 min after induction (T1), 60 min after induction (T2), immediately after surgery (T3), and on arrival at the post-anesthesia care unit (T4). Results: Peak and plateau airway pressures were significantly lower in group 1:1 than in group 1:2 at T1 (p=0.044 and 0.048, respectively). The dynamic and static compliances were significantly higher in group 1:1 than in group 1:2 at T1 (p=0.044 and 0.045, respectively). However, the partial pressure of oxygen did not significantly differ between groups. Conclusion Compared to a 1:2 I:E ratio, a 1:1 I:E ratio improved dynamic compliance and lowered the peak airway pressure without complications in pediatric patients. Nevertheless, our results do not support its use solely for improving oxygenation.

PURPOSE: In children on anticancer chemotherapy, bloodstream infections (BSIs) are a major cause of morbidity and mortality. We investigated febrile episodes and bloodstream infections in pediatric cancer patients to guide proper selection of empiric antibiotics for febrile pediatric hemato-oncologic patients. METHODS: All febrile episodes treated in the division of hematology-oncology, the department of pediatrics, Hanyang University Hospital, between July 2005 and June 2008 were reviewed. Episodes with and without bloodstream infections were compared. RESULTS: Forty cases (18.9%, 25 patients) of BSI occurred in 212 febrile episodes (63 patients). Thirty-seven cases (23.6%, 22 patients) of BSI occurred in 157 febrile episodes with neutropenia (54 patients). Microorganisms identified in BSI corresponded to 23 gram-positive bacteria (51.2%), 20 gram-negative bacteria (44.5%), and 2 fungi (4.4%). Rates of BSI between those who had received umbilical cord blood transplantation and those who had received transplantation from other source were significantly different (55.0% vs. 7.7%, P=0.001). No differences in mortality rate were observed among organisms in BSI patients. For febrile episodes the rate of BSI was higher among those with Chemoport than those with Hickman catheter (P=0.029) and gram-positive pathogens were more likely to be associated with Chemoport (P=0.001). CONCLUSION: The study showed the rate of BSI, distribution of pathogens with regard to neutropenia, transplantation, central venous catheters, and antimicrobial susceptibility of pathogens in order to help guide in the choice of optimal empiric antibiotics in pediatric febrile neutropenic hemato-oncologic patients.

PURPOSE: To examine the degree of depression and anxiety in Korean patients with age-related macular degeneration (AMD) and to evaluate the influence of mood disturbance on patient's treatment satisfaction and compliance. METHODS: Forty-four patients with AMD and thirty-three controls comprised the study populations. Patients and controls rated themselves on the Korean Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI). The effect of mood disturbance on the patient's satisfaction and compliance was evaluated. RESULTS: The depression and anxiety scores were significantly higher in patients with AMD. The mood disturbance was negatively correlated with the patient's satisfaction and compliance. 14 patients (31.8%) were lost to follow-up 1 year later. The depression and anxiety scores of these patients were higher than those of remaining thirty patients. CONCLUSIONS: Depression and anxiety of patients with AMD affect on patient's satisfaction and compliance. So recognition and management of mood disturbance may help improving visual function and maintaining quality of life in patients.

PURPOSE: This study was performed to investigate the epidemiological trend of rotavirus acute gastroenteritis (RV-AGE) in children. METHODS: A retrospective review was performed in patients (1 month to 18 years of age) with acute gastroenteritis at KEPCO Medical Center from September 2004 to August 2013. Comparative analyses were performed based on periods: pre-vaccine (2004-2006) and post-vaccine (2008-2012) in all patients; 2004-2006 (period A), 2007-2009 (period B) and 2010-2012 (period C) in patients under 5 years of age. RESULTS: Proportion of RV-AGE decreased from 25.0% (337/1,346) in pre-vaccine period to 20.8% (459/2,210) in post-vaccine period (rate ratio (RR), 0.83 [95% CI, 0.73-0.93]; P=0.0029). The median age of patients with RV-AGE in post-vaccine period (2.6 years) was significantly (P<0.0001) higher than that in pre-vaccine period (1.6 years). In patients hospitalized with AGE, proportion of RV-AGE was significantly reduced in patients 6 to 23 months old (RR, 0.62 [95% CI, 0.51-0.75]; P<0.0001). Significant decline in proportion of RV-AGE was observed in patients under 5 years of age: period A, 26.9% (308/1,144); period B, 22.7% (295/1,299); period C, 20.6% (186/902) (P=0.0007). After the introduction of rotavirus vaccine, a significant decreasing trend of RV-AGE proportion was observed in patients 6 to 11 months old (P=0.0018) and 12 to 23 months old (P=0.0152). CONCLUSION: Decrease in RV-AGE proportion and increase in age of patients with RV-AGE were observed after the introduction of rotavirus vaccine in this single center study. Continued and systematic surveillance is needed to assess the impact of rotavirus vaccine.
