PURPOSE: To examine changes in ocular torsion after the weakening procedure for the inferior oblique muscle in patients with overaction of inferior oblique muscle (IOOA). METHODS: Twenty-eight eyes that had undergone the graded IO anteriorization combined with recession were evaluated. Twelve eyes from 11 patients had IOOA due to superior oblique muscle palsy (SOP) and 16 eyes from 9 patients had primary IOOA. Fundus photograph was taken to examine changes in torsional deviation before and after surgery. RESULTS: The average torsional deviation decreased from +17.5 +/- 7.3 degrees before surgery to +6.4 +/- 5.8 degrees after surgery, with the amount of correction being 11.1 degrees. It was corrected by 12.6, from +19.1 +/- 7.7 degrees to +6.5 +/- 4.8 degrees, in patients with SOP, and by 10 degrees, from +16.3 +/- 6.9 degrees to +6.3 +/- 6.6 degrees, in patients with IOOA (p<0.05). CONCLUSIONS: About 11o excyclotorsional correction was observed in patients with IOOA after IO anteriorization combined with recession.

PURPOSE: We report a first case of Weaver syndrome in Korea, accompanied by alternating exotropia and visual disturbance. METHODS: An 11-month-old girl showed the characteristic symptoms of Weaver syndrome along with alternating exotropia and visual disturbance. RESULTS: Ophthalmologic findings included alternating exotropia, hypertelorism, down-slanting palpebral fissure, and telecanthus. The angle of exotropia according to the Krimsky's test was 60 prism diopters. No limitation of extraocular movement was present. Visual acuity of both eyes showed poor following fixation. According to brain MRI, immature myelination of the anterior limb of the internal capsule, contracture and sclerotic changes of the optic canal and superior oblique fissure were present. Both optical nerves ran abnormally crooked. CONCLUSIONS: The author experienced a child with Weaver syndrome who showed alternating exotropia, visual disturbance, and characteristic findings according to brain MRI. Thus, we report one case of Weaver syndrome never been reported in Korea with the literature study.

Purpose: Exercise is known to reduce proinflammatory cytokines production and apoptosis. We investigated the effect of treadmill running on spatial learning memory in terms of activation of nuclear factor kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathway in Alzheimer disease (AD) rats. We also evaluated the effect of treadmill running on proinflammatory cytokine production and apoptosis. Methods: Using the stereotaxic frame, amyloid-β (Aβ) was injected into the lateral ventricle of the brain. The rats belong to treadmill running groups were forced to run on a motorized treadmill for 30 minutes per a day during 4 weeks, starting 3 days after Aβ injection. Morris water maze task was done for the determination of spatial learning memory. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay, immunohistochemistry for cleaved caspase-3, and western blot for NF-κB, inhibitory protein of NF-κB (IκB), MAPK signaling pathway, tumor necrosis factor (TNF)-α, interleukin (IL)-1β were done. Results: Induction of AD increased proinflammatory cytokine secretion by activating the NF-κB/MAPK signaling pathway. These changes induced apoptosis in the hippocampus and reduced spatial learning memory. In contrast, treadmill running inactivated the NF-κB/MAPK signaling pathway and suppressed proinflammatory cytokine production. These changes inhibited apoptosis and improved spatial learning memory. Conclusions Current results showed that treadmill running promoted spatial learning memory through suppressing proinflammatory cytokine production and apoptosis via inactivation of NF-κB/MAPK signaling pathway. Treadmill exercise can be considered an effective intervention for symptom relieve of AD.

Objective: The purpose of this study was to identify the associations of chronic physical disease between patients with severe mental illness (SMI) and the general population of South Korea. Methods: This study was conducted with National Health Insurance Corporation data from 2014 to 2019. A total of 848,058 people were diagnosed with SMI in this period, and the same number of controls were established by matching by sex and age. A descriptive analysis was conducted on the sociodemographic characteristics of patients with SMI. Conditional logistic regression analysis was performed to identify the associations between comorbid physical disease in patients with SMI and those of the general population. SAS Enterprise Guide 7.1 (SAS Inc, Cary, NC, USA) were used to perform all statistical tests. Results: The analysis revealed significant differences in medical insurance, income level, and Charlson Comorbidity Index weighted by chronic physical disease, between patients with SMI and the general population. Conditional logistic regression analysis between the two groups also revealed significant differences in eight chronic physical diseases except hypertensive disease. Conclusion This study confirmed the vulnerability of patients with SMI to chronic physical diseases and we were able to identify chronic physical disease that were highly related to patients with SMI.

BACKGROUND: Anti-tuberculosis drugs used in combination cause adverse drug reactions, but the prevalence of the reactions and risk factors have not been determined. This study aims to identify the prevalence and risk factors of adverse drug reactions (ADR) to the use of first line anti-tuberculosis drugs. METHODS: A total of 435 newly diagnosed patients with tuberculosis (44.1 years+/-19.0 years) were eligible for this study. All patients received daily oral isoniazid (300 or 400 mg), rifampicin (450 or 600 mg) and ethambutol (800 mg) for 6 months, and pyrazinamide (20 mg/kg) for 2 months. Blood tests were performed regularly (before treatment, 2 weeks after treatment, and bimonthly there after). Patients were interviewed 2 months and 6 months after treatment. A serious ADR was defined as any ADR that resulted in the discontinuation of one or more of the drugs. RESULTS: An ADR was noted in 52.6% of all patients. Gastrointestinal (19.3%), cutaneous (17.7%), hepatic (13.8%), renal (12.6%), and neurological (10.3%) ADRs were frequent and hematological (4.4%), musculoskeletal (3.0%) ADRs were less frequent. A skin ADR was associated with an elevated baseline of liver enzymes (odds ratio, 3.48; 95% CI, 1.2 to 9.9), whereas a hepatic ADR was associated with a history of chronic liver disease (odds ratio, 4.82; 95% CI, 1.7 to 13.2). The prevalence of any serious ADR was 9.7%. Occurrence of any serious ADR was associated with a history of chronic liver disease (odds ratio, 4.29; 95% CI, 1.4 to 13.6). CONCLUSIONS: Anti-tuberculosis drugs given in combination frequently caused a ADR and the findings suggest that a patient receiving anti-tuberculosis treatment should be closely monitored.

Mulberry (Morus spp.) is a widespread deciduous tree and its fruit is commonly eaten in Korea and eastern Asia. Some reports demonstrate that mulberry fruit is a food allergen in the Mediterranean area. However, there has been no report of systemic allergic reactions after ingesting mulberry fruit in Korea. An 18-year-old boy with a mulberry fruit allergy visited our allergy clinic. He had experienced generalized urticaria, chest tightness, breathing difficulty, and abdominal cramping after ingesting mulberry fruit. The patient had a positive skin reaction to mulberry fruit extract (mean wheal size, 5 mm). We performed an ELISA to detect specific IgE antibody (Ab) to mulberry fruit extract in the patient's serum compared to those of non-atopic healthy controls and birch-sensitized individuals. Specific IgE Ab to mulberry fruit extract was detected in the patient's serum, as compared to non-atopic healthy controls. Another subject, who was strongly sensitized to birch pollen, also had a positive serum-specific IgE Ab to mulberry fruit. We performed IgE immunoblot analysis using the patient's and the other subject's sera, who had serum-specific IgE to mulberry fruit, to identify the IgE-binding component. An identical IgE-binding component to mulberry extract was detected in the two subjects at around 17 kDa, and which might be PR 10 of Bet v 1. In conclusion, mulberry fruit could induce a systemic allergic reaction through an IgE-mediated mechanism, and cross-reactivity might occur between mulberry fruit and birch pollen.

In the PALOMA-3 trial, the median progression-free survival (PFS) was longer among patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2−) advanced breast cancer (ABC) treated with palbociclib plus fulvestrant than those treated with placebo plus fulvestrant. This subgroup analysis examined the efficacy and safety of palbociclib among Korean patients enrolled in PALOMA-3 (n = 43 [palbociclib group, n = 24; placebo group, n = 19]). In both groups, > 40% of patients were pre/perimenopausal at enrollment. The median PFS was significantly prolonged with palbociclib vs. placebo (12.3 [95% confidence interval (CI), 9.1–not estimable] vs. 5.4 months [95% CI, 1.9–9.2]; hazard ratio, 0.40 [95% CI, 0.19–0.83]; one-sided p = 0.005), and the confirmed objective response was 21.1% and 11.8%, respectively (odds ratio, 2.0 [95% CI, 0.24–24.8]). Neutropenia was the most common adverse event associated with palbociclib. Overall, palbociclib plus fulvestrant was effective and generally safe among Korean patients with HR+/HER2− ABC, regardless of menopausal status.
