Purpose:
To compare the myopic progression between pateints only wearing glasses (Myopia group) and patients using low-dose atropine with glasses (Atropine group) for 1 years or more.
Methods:
Medical records were retrospectively reviewed. Low-dose atropine (atropine sulfate 0.125%) and artificial tear eyedrops (sodium hyaluronate 0.1%) were applied immediately afterwards to both eyes daily to the Atropine group. All children regularly visited our clinic for measurement of refractive power, axial length, near-point accomodation, pupil diameter, symptoms (glare, near-work disturbance, headache, allergic reaction, dryness) were recorded.
Results:
A total of 240 patients were included. Atropine was prescribed for 138 patients, the Atropine group, and the remaining 102 patients constituted the Myopia group, and were observed for 20.3 ± 7.8 months. In the initial visit, the mean refractive power was -4.2 ± 1.4 diopters (D) for the Myopia group, -4.8 ± 1.9 D for the Atropine group, and the mean axial length was 24.5 ± 0.6 mm for the Myopia group, 25.1 ± 0.9 mm for the Atropine group. During follow up, in the Myopia group, mean refractive power changed -0.10 ± 0.12 D/month, and mean axial length changed 0.06 ± 0.01 mm/month. In the Atropine group, mean refractive power changed -0.03 ± 0.04 D/month, and mean axial length changed 0.02 ± 0.02 mm/month. The pupil size of the Atropine group was 6.1 ± 0.8 mm, with 30 patients presenting symptoms.
Conclusions
Refractive power progression and axial length elongation was significantly lesser in the Atropine group than the Myopic group. Pupil diameter increased in the Atropine group, and 21% of the Atropine group complained of symptoms. Using low-dose atropine for more than 1 year was effective to suppress refractive power progression and axial length elongation.

Halitosis is a very common disease that affects the majority of the population and is characterized by unpleasant odor during expiration. Anaerobic bacteria produce a range of malodorous substances including volatile sulfur compounds. To reduce oral malodor, the amount of oral microorganisms should be managed through brushing, scraping, and use of antibacterial agents. In this study, a mouthwash containing 0.05% cetylpyridinium chloride was tested on 22 candidates with oral malodor for two weeks to confirm oral malodor reduction through the use of antibacterial mouthwashes. Volatile sulfur compound measurements were significantly lower after using the mouthwash than before using it; thus, the mouthwash effectively reduced oral malodor.

Guillain-Barre syndrome (GBS) is usually characterized by acute areflexic ascending paralysis with minimal sensory involvement. Only a few cases of GBS associated with scrub typhus have been reported. Previous case reports focused on the laboratory findings, pathogenesis, and clinical manifestation. Unlike the previous case, neuropathic pain was a prominent symptom of GBS in our case. We report scrub-typhus-related GBS with a detailed description of the clinical manifestations, especially neuropathic pain, along with results of serial follow-up electrodiagnostic studies.

Background:
Lawsonia intracellularis is the causative agent of proliferative enteropathy and is associated with several outbreaks, causing substantial economic loss to the porcine industry.
Objectives:
In this study, we focused on demonstrating the protective effect in the mouse model through the immunological bases of two vaccine strains against porcine proliferative enteritis.
Methods:
We used live-attenuated Salmonella Typhimurium (ST) secreting two selected immunogenic LI antigens (Lawsonia autotransporter A epitopes and flagellin [FliC]-peptidoglycan-associated lipoprotein-FliC) as the vaccine carrier. The constructs were cloned into a Salmonella expression vector (pJHL65) and transformed into the ST strain (JOL912). The expression of immunogenic proteins within Salmonella was evaluated via immunoblotting.
Results:
Immunizing BALB/c mice orally and subcutaneously induced high levels of LI-specific systemic immunoglobulin G and mucosal secretory immunoglobulin A. In immunized mice, there was significant upregulation of interferon-γ and interleukin-4 cytokine mRNA and an increase in the subpopulations of cluster of differentiation (CD) 4+ and CD 8+ T lymphocytes upon splenocytes re-stimulation with LI antigens. We observed significant protection in C57BL/6 mice against challenge with 106.9 times the median tissue culture infectious dose of LI or 2 × 109 colony-forming units of the virulent ST strain. Immunizing mice with either individual vaccine strains or co-mixture inhibited bacterial proliferation, with a marked reduction in the percentage of mice shedding Lawsonia in their feces.
Conclusions
Salmonella-mediated LI gene delivery induces robust humoral and cellular immune reactions, leading to significant protection against LI and salmonellosis.

Severe fever with thrombocytopenia syndrome (SFTS) is a zoonotic disease, and its clinical information and prevalence are important. This study was conducted on 22 feline patients from the Republic of Korea (ROK), suspected to suffer from a tick-borne disease. Four cats were positive for SFTS, and genotypes B-1, B-3, D, and F were identified. Clinical symptoms, such as anorexia, jaundice, thrombocytopenia, leukopenia, and hyperbilirubinemia, were detected. This is the first report of SFTS virus genotypes B-1, D, and F from cats in the ROK.Moreover, our results suggest that jaundice may be an indicator of SFTS in cats.
