1.Results of Cultured Silicone Tubes Inserted in Congenital Nasolacrimal Duct Obstruction.
Journal of the Korean Ophthalmological Society 2014;55(8):1121-1125
PURPOSE: We evaluated cultured specimens from silicone tubes removed from patients with congenital nasolacrimal duct obstruction and determined the antibiotic sensitivities of the specimens. METHODS: This study included 26 eyes of 22 patients who had received endonasal silicone tube intubation for congenital nasolacrimal duct obstruction. The removed silicone tubes were divided into canaliculus, lacrimal sac, nasolacrimal duct and nasal cavity parts according to insertion state. Then, bacteria and fungus cultures were performed and their antibiotic sensitivity was tested. RESULTS: Bacteria culture rate was 80.8% in the canaliculus and the lacrimal sac, and 88.5% in the lacrimal duct, and the nasal cavity, which was not significantly different according to insertion site. Fungus culture rate was significantly higher in the nasal cavity than in the nasolacrimal duct and in the nasolacrimal duct than in the lacrimal sac and the canaliculus (p-value < 0.05). The species of cultured Gram-positive bacteria were in the following order: Staphylococcus aureus, Streptococcus pneumonia and coagulase negative Staphylococcus. Common species of cultured Gram-negative bacteria were Pseudomonas and Serratia marcescens. All six species of cultured fungi were Candida. Among 12 Staphylococcus aureus cultured, eight species showed resistance to methicillin (MRSA). In all patients, the symptoms and the signs of nasolacrimal duct obstruction improved after the tube removal. CONCLUSIONS: Bacterial and fungal infection of the silicone tube in patients with congenital nasolacrimal duct obstruction does not appear to affect directly the outcome of silicone tube intubation. Further studies of bacterium and fungi in the nasolacrimal duct before silicone tube intubation are needed for determining the infection causing nasolacrimal duct obstruction.

2.Diagnosis and Management of Thyroid Disease during Pregnancy and Postpartum: 2023 Revised Korean Thyroid Association Guidelines
Endocrinology and Metabolism 2023;38(3):289-294
Thyroid hormone plays a critical role in fetal growth and development, and thyroid dysfunction during pregnancy is associated with several adverse outcomes, such as miscarriage and preterm birth. In this review, we introduce and explain three major changes in the revised Korean Thyroid Association (KTA) guidelines for the diagnosis and management of thyroid disease during pregnancy: first, the normal range of thyroid-stimulating hormone (TSH) during pregnancy; second, the treatment of subclinical hypothyroidism; and third, the management of euthyroid pregnant women with positive thyroid autoantibodies. The revised KTA guidelines adopt 4.0 mIU/L as the upper limit of TSH in the first trimester. A TSH level between 4.0 and 10.0 mIU/L, combined with free thyroxine (T4) within the normal range, is defined as subclinical hypothyroidism, and a TSH level over 10 mIU/L is defined as overt hypothyroidism regardless of the free T4 level. Levothyroxine treatment is recommended when the TSH level is higher than 4 mIU/L in subclinical hypothyroidism, regardless of thyroid peroxidase antibody positivity. However, thyroid hormone therapy to prevent miscarriage is not recommended in thyroid autoantibody-positive women with normal thyroid function.

PURPOSE: To report the clinical effect of an eyelid stretching exercise in 8 cases of overcorrected congenital ptosis after levator resection and present a literature review. CASE SUMMARY: Eyelid stretching exercise was performed by pushing the margin of the upper eyelid down. If margin reflex distance 1 (MRD1) asymmetry was larger than 1.5 mm compared with the other eyelid after the stretching exercise for 2 weeks, the exercise was extended for 1 more week. This study included 8 eyes of 8 patients who performed eyelid stretching exercise for 2 weeks when overcorrected 1 week after undergoing levator resection. We compared preoperative MRD1 and postoperative MRD1s for 1 month. Overcorrection was corrected satisfactorily in all patients with bilateral symmetry with eyelid stretching exercise for 2 weeks. Additional exercise did not affect MRD1. CONCLUSIONS: In congenital ptosis overcorrected after levator resection, medical treatment including eyelid stretching exercise could be considered before undergoing a secondary operation. Eyelid stretching exercise can be effective when performed early before fibrous tissue bonds are too firm.

The levels of ergothioneine (ERG), which have been shown to act as an excellent antioxidant, were determined in both fruiting bodies and mycelia of various mushroom species. We found that ERG accumulated at different levels in fruiting bodies of mushrooms and showed up to a 92.3-fold difference between mushrooms. We also found that ERG accumulated at higher levels in mycelia than in fruiting bodies of economically important mushroom species such as Ganoderma neo-japonicum, G. applanatum and Paecilomyces tenuipes. The addition of 2 mM methionine (Met) to mycelial culture medium increased the ERG contents in most mushroom species tested, indicating that Met is a good additive to enhance the ERG levels in a variety of mushroom species. Taking these results into consideration, we suggest that the addition of Met to the mycelial culture medium is an efficient way to enhance the antioxidant properties in economically important mushroom species.

Background:
Hypothyroidism, a prevalent endocrine disorder, results from insufficient thyroid hormone production or release, affecting metabolism. However, disparities in comorbidities and treatment trajectories may exist between endogenous and exogenous hypothyroidism.
Methods:
Data from the Korean National Health Insurance Service from 2004 to 2018. Endogenous hypothyroidism was defined as cases with two or more diagnostic codes for hypothyroidism coupled with a history of thyroid hormone intake exceeding 60 days. To eliminate iatrogenic hypothyroidism, individuals with diagnosis codes for thyroid cancer, treatment codes for thyroid surgery, or radiotherapy were excluded. Hypothyroidism-related comorbidities were defined as new occurrences of the corresponding diagnosis code after the diagnosis of hypothyroidism during the entire study period.
Results:
The age-standardized incidence of endogenous hypothyroidism among men was 0.2 per 1,000 person-years in 2004, increasing to 0.8 in 2018. Among women, the incidence increased from 1.6 per 1,000 person-years in 2004 to 3.7 in 2018. When comparing age groups of 20s–50s and 60s–90s, both sexes in the 60s–90s demonstrated a more rapid increase in incidence than those in the 20s–50s age range. Patients with endogenous hypothyroidism demonstrated a higher incidence of mood disorders across all age groups and cerebrovascular disease in individuals ≥60 years old, regardless of sex.
Conclusion
In Republic of Korea, endogenous hypothyroidism incidence has been increased in recent years. The incidence of endogenous hypothyroidism is increasing more rapidly in men than in women, especially in the elderly. Patients with endogenous hypothyroidism seem to have a heightened risk for cerebrovascular disease and mood disorders.

Endocrinology and Metabolism 2023;38(4):436-444
Background:
This study aimed to investigate the changes of incidence and treatment of choice for hyperthyroidism from 2003 to 2018 and explore the treatment-related complications and concomitant comorbidities in South Korea using data from the National Health Insurance Service.
Methods:
This is a retrospective observational study. Hyperthyroidism was defined as a case having two or more diagnostic codes of thyrotoxicosis, with antithyroid drug intake for more than 6 months.
Results:
The average age-standardized incidence of hyperthyroidism from 2003 to 2018 was 42.23 and 105.13 per 100,000 men and women, respectively. In 2003 to 2004, hyperthyroidism was most often diagnosed in patients in their 50s, but in 2017 to 2018, people were most often diagnosed in their 60s. During the entire period, about 93.7% of hyperthyroidism patients were prescribed with antithyroid drugs, and meanwhile, the annual rates of ablation therapy decrease from 7.68% in 2008 to 4.56% in 2018. Antithyroid drug-related adverse events, mainly agranulocytosis and acute hepatitis, as well as complications of hyperthyroidism such as atrial fibrillation or flutter, osteoporosis, and fractures, occurred more often in younger patients.
Conclusion
In Korea, hyperthyroidism occurred about 2.5 times more in women than in men, and antithyroid drugs were most preferred as the first-line treatment. Compared to the general population, hyperthyroid patients may have a higher risk of atrial fibrillation or flutter, osteoporosis, and fractures at a younger age.
