This study presents the development and validation of a risk assessment program of highly pathogenic avian influenza (HPAI). This program was developed by the Korean government (Animal and Plant Quarantine Agency) and a private corporation (Korea Telecom, KT), using a national database (Korean animal health integrated system, KAHIS).

The purpose of this study was to investigate the stress distribution and intensity derived from the transpalatal lingual arch in the investing bone composed of photoelastic material(PL-3). The transpalatal lingual arch wire was deflected in the horizontal and vertical direction to give the various conditions. The two-dimensional photoelastic stress analysis was performed, and the stress distrebution was recored by photofraphy. The results were as follows: 1. In bilateral expansion, as horizontal deflection was singly applied, the stress was more concentrated on the root apex in square free end than round. In square free end, as vertical deflection was increased gradually, the black line meaning center of rotation moced inferiorly togerher with the increment of whole fringes. 2. In application of vertical deflection on anchorage side for unilateral expansion, the stress distribution that expansive force leaned to expansion side was observed. As vertical deflection increased, the extruding stress was obesrved on molar of expansion side. And as horisontal deflection increased, the tipping stress on the molar of anchorage side was observed. 3. In unilateral rotation with the asymmetric toe-in, the fringe appeared on the distal aspect of root apex.

Saethre-Chotzen syndrome is an autosomal dominant craniosynostosis syndrome, usually involving unior bilateral coronal synostosis and mild limb deformities, and is induced by loss-of-function mutations of the TWIST1 gene. Other clinical features of this syndrome include ptosis, low-set ears, hearing loss, hypertelorism, broad great toes, clinodactyly, and syndactyly. The authors of the present study report 2 children with clinical features of Saethre-Chotzen syndrome who showed mutations in the TWIST1 gene, and is the first molecular genetic confirmation of Saethre-Chotzen syndrome in Korea. The molecular genetic testing of the TWIST1 gene for patients with coronal synostoses is important to confirm the diagnosis and to provide adequate genetic counseling.

OBJECTIVES: This study investigated the reporting rates of adverse events following immunization (AEFIs) to the spontaneous reporting system (SRS) and its predictors among individuals with AEFIs after coronavirus disease 2019 (COVID-19) vaccination. METHODS: A cross-sectional, web-based survey was conducted from December 2, 2021 to December 20, 2021, recruiting participants >14 days after completion of a primary COVID-19 vaccination series. Reporting rates were calculated by dividing the number of participants who reported AEFIs to the SRS by the total number of participants who experienced AEFIs. We estimated adjusted odds ratios (aORs) using multivariate logistic regression to determine factors associated with spontaneous AEFIs reporting. RESULTS: Among 2,993 participants, 90.9% and 88.7% experienced AEFIs after the first and second vaccine doses, respectively (reporting rates, 11.6 and 12.7%). Furthermore, 3.3% and 4.2% suffered moderate to severe AEFIs, respectively (reporting rates, 50.5 and 50.0%). Spontaneous reporting was more prevalent in female (aOR, 1.54; 95% confidence interval [CI], 1.31 to 1.81); those with moderate to severe AEFIs (aOR, 5.47; 95% CI, 4.45 to 6.73), comorbidities (aOR, 1.31; 95% CI, 1.09 to 1.57), a history of severe allergic reactions (aOR, 2.02; 95% CI, 1.47 to 2.77); and those who had received mRNA-1273 (aOR, 1.25; 95% CI, 1.05 to 1.49) or ChAdOx1 (aOR, 1.62; 95% CI, 1.15 to 2.30) vaccines versus BNT162b2. Reporting was less likely in older individuals (aOR, 0.98; 95% CI, 0.98 to 0.99 per 1-year age increment). CONCLUSIONS Spontaneous reporting of AEFIs after COVID-19 vaccination was associated with younger age, female sex, moderate to severe AEFIs, comorbidities, history of allergic reactions, and vaccine type. AEFIs under-reporting should be considered when delivering information to the community and in public health decision-making.

Splenic artery aneurysms are an uncommon form of vascular disease that carry the risk of rupture and fatal hemorrhage. Precise cause of splenic artery aneurysms are not be established, the most common pathologic finding is defect of the media. Splenic artery aneurysms occur in patient with multiple pregnancies, portal hypertension, splenomegaly, after orthotopic liver transplantation and fibrodysplasia. Most patients who are diagnosised with splenic artery aneurysm are asymptomatic. Arteriography is a confirmed diagnostic method for detecting splenic artery aneurysms and searching the location of aneurysms. Operative treatment and therapeutic catheter embolization have been used for treatment of splenic artery aneurysms.

The aims of this study were to determine the short-term effectiveness of an internet-based lifestyle modification (LSM) program in preventing the onset of type 2 diabetes mellitus (T2DM) in prediabetes patients in community settings. A total of 415 subjects who were diagnosed with prediabetes were randomly assigned to the LSM and standard management (SM) groups. After the 6-month intervention, the LSM group had a statistically significant reduction in body weight, body mass index compared to the SM group participants. In the LSM group, blood glucose levels were significantly decreased after intervention and the clinical improvement effect was evident in the group that achieved the target weight loss of 5% or more of the initial weight for 6 months. Internet-based 6-month-intensive LSM programs conducted by public health center personnel are an effective way to provide lifestyle intervention programs and encourage maintenance of healthy behaviors in subjects with a high risk of T2DM in community settings.

Primary systemic amyloidosis is a progressive disease that is frequently fatal. Nephrotic syndrome is present in almost one-third, congestive heart failure in one-quarter, and peripheral neuropathy in one-sixth of patients at the time of diagnosis. If heart or renal failure are presented, survival rate is poor. We experienced a case of a 66 year-old female patient who had complained lower leg edema and paresthesia of extremities for about 5 months. The laboratory findings were consistent with nephrotic syndrome, but the lower leg edema was non-pitting and the cause of paresthesia was unknown. We performed kidney and nerve biopsy and confirmed a case of primary systemic amyloidosis. In this case, presence of postural hypotension, probable cardiac involvement and relatively long spikes along the outside of the glomerular capillary loops on methenamine silver stain is suggestive of poor prognosis. We can predict chronic renal failure and congestive heart failure in the course of this case. We report a case of primary systemic amyloidosis predominantly presenting nephrotic syndrome and peripheral neuropathy with review of related literatures.

We report a case of a premature newborn baby who presented with hyponatremia, hyperkalemia, and metabolic acidosis accompanied by severe polyhydramnios in utero. The baby was diagnosed with pseudohypoaldosteronism on the basis of normal 17-hydroxyprogesterone levels, elevated aldosterone, and clinical symptoms. His serum electrolyte levels were corrected with sodium chloride supplementation. Sodium supplementation was reduced gradually and discontinued at 5 months of age. At 5 months, the child was able to maintain normal serum electrolyte levels without oral sodium chloride supplementation, and showed normal physical and neurological development. This case illustrates that pseudohypoaldosteronism must be considered if a newborn infant with an antenatal history of severe polyhydramnios shows excessive salt loss with normal levels of 17-hydroxyprogesterone.

PURPOSE: To evaluate visual performance as well as patient satisfaction and to explore factors associated with clinical outcomes in pseudophakic monovision acquired after bilateral phacoemulsification and sequential monofocal intraocular lens (IOL) implantation. METHODS: The present retrospective study examined patients with pseudophakic monovision. Preoperative and postoperative binocular uncorrected distant visual acuity (UCDVA), uncorrected near visual acuity (UCNVA), refractive errors and postoperative near stereopsis were measured. Postoperative measurements were obtained at least 6 months after the fellow eye surgery. Patient satisfaction and independence from glasses were evaluated using a questionnaire. RESULTS: Preoperative and postoperative binocular UCDVA, UCNVA, and differences in spherical equivalent refractive error were statistically significant. Postoperative near stereopsis was 107.1 arcsec. Questionnaire responses showed that 71.4% of patients were less dependent on glasses and 85.7% were satisfied with the postoperative visual performance. Various designs of monovision, such as crossed monovision or customized minimonovision with moderate myopic defocus showed the same level of patient satisfaction. Patients who were older than 60 years or had poorer preoperative binocular UCDVA showed higher satisfaction. CONCLUSIONS: Pseudophakic monovision is an effective approach for managing loss of accommodation after cataract surgery, especially in patients older than 60 years.
