Objectives: The purpose of this study was to identify the effectiveness of COVID-19 vaccinations on deaths of the COVID-19 cases in some elderly long-term care facilities (LTCF) in Gwangju Metropolitan City. Methods: The study subjects were 659 COVID-19 cases in residents of 7 elderly LTCF, Gwangju, from 21 Dec. 2021 to 28 Jan. 2022. The used variables were confirmed dates for COVID-19, demographic characteristics, co-morbidities, presentation of symptoms, death and vaccination related characteristics including type of vaccine, doses and dates. Vaccination status were classified as not vaccinated, partially and fully vaccinated. The associations of vaccination status and deaths of COVID-19 cases were tested by chi-square test and multiple logistic regression analysis. Results: The rates of not vaccinated, partially vaccinated and fully vaccinated were 19.4%, 10.2% and 70.4%, respectively. The mortality rate of the cases was 6.4%.The death rate by vaccination status was 16.4% in not vaccinated, 15.4% in partially vaccinated and 2.6% in fully vaccinated, showing a statistically significant difference. The adjusted odds ratios (ORs) (95% confidence intervals, CIs) of death compared to fully vaccinated were 7.64 (3.87-16.34) in non-vaccinated, and 6.97 (3.44-14.14) in partially vaccinated. Conclusions COVID-19 vaccination seems to work effectively in preventing deaths of COVID-19 cases of elderly LTCF residents. This finding support that fully vaccinations in high risk group such as elderly LTCF residents is very important for one of strategies of COVID-19 management.

PURPOSE: Encephalitis is a cranial nervous system infection that is caused by various etiologies. Most of the patients with encephalitis undergo severe or fatal clinical course with sequelae. This study was conducted to estimate the clinical outcomes and to evaluate factors which can be used to predict clinical outcomes among pediatric patients with encephalitis METHODS: We retrospectively reviewed 46 patients with encephalitis who were admitted to the Department of Pediatrics of Chonbuk National University Hospital, from July 1995 to July 2003. Encephalitis was diagnosed based on the presence of neurologic abnormalities, CSF, Brain CT or MRI findings. Information on sequelae was obtained in the outpatient clinic. RESULTS: In this study, five patients(11.6%) were expired, 17 patients(39.5%) developed neurologic sequelaes and 21 patients(46.5%) were recovered without sequelae. Infants had poorer outcomes compared to older age groups. Twenty nine cases who had seizures showed high morbidity rate(48.3%) compared to the seizure-free group(17.6%). Among six patients with status epilepticus, four(66.7%) developed neurologic sequelae and two(33.3%) expired. The group with normal brain MRI findings had better outcomes (70%) than the group with abnormal MRI findings(55.5%). Gray matter involved patients on MRI had poorer recovery rate(33.3%) than white matter involved patients(69.2%). The group treated with intravenous immunoglobulin(IVIG) had better outcomes(64.7%) than the other group(37.9%). CONCLUSION: The presence of seizure, younger patients, and presence of abnormal findings of brain MRI, especially gray matter lesions were associated with poor clinical outcomes in children with encephalitis.

A 36-year-old male patient with no remarkable medical history was admitted to our hospital for a health check up. On chest radiography, bilateral aortic notches at the level of aortic arch were shown suggesting aortic arch anomaly without any clinical symptoms. Two aortic arches were almost same-in-size on suprasternal view of transthoracic echocardiography. In addition, multidetector computed tomography showed balanced type double aortic arch forming a complete vascular ring which encircled the trachea and esophagus. The trachea was slightly compressed by the vascular ring whereas the esophagus was intact. Nevertheless, the pulmonary function test was normal. The patient was discharged from hospital with instructions for periodic follow-up.

BACKGROUND: Repeated administration of morphine leads to characteristic tolerance. We tested the effects of intrathecal oxcarbazepine (OXC) on spinal morphine tolerance in rats using the tail flick test. METHODS: Sprague-Dawley rats received intrathecal injections of 10 microliter saline alone, or 10 microliter of solutions containing 100 microgram OXC, 15 microgram morphine, or OXC + morphine for 7 days. Different groups of rats received OXC on days 1-7, 1-3, or 5-7. The tail-flick assay was used to measure acute and chronic nociception. The nociceptive stimulus consisted of dipping the distal 5 cm of the tail into warm water before and 30 min after drug injection. On day 8, an antinociceptive dose-response curve was plotted, and the 50% effective dose for morphine (given alone) was determined for all groups. RESULTS: Morphine or OXC both produced acute antinociception; OXC + morphine resulted in a significantly larger response than obtained with morphine alone. Morphine tolerance was produced by intrathecal injection of morphine over 7 days. Co-administration of morphine and OXC completely blocked morphine tolerance, but tolerance developed when OXC injection was stopped, and morphine potency was partially restored by co-administration of OXC in tolerant rats. CONCLUSIONS: The antinociceptive effect of both acute and chronic morphine therapy is increased with intrathecal OXC, and antinociceptive morphine tolerance is attenuated in rats.

PURPOSE: The purposes of this study were to evaluate the marginal and internal gaps, and the potential clinical applications of three different methods of dental prostheses fabrication, and to compare the prostheses prepared using the silicone replica technique (SRT) and those prepared using the three-dimensional superimposition analysis (3DSA). MATERIALS AND METHODS: Five Pekkton, lithium disilicate, and zirconia crowns were each manufactured and tested using both the SRT and the two-dimensional section of the 3DSA. The data were analyzed with the nonparametric version of a two-way analysis of variance using rank-transformed values and the Tukey's post-hoc test (α = .05). RESULTS: Significant differences were observed between the fabrication methods in the marginal gap (P < .010), deep chamfer (P < .001), axial wall (P < .001), and occlusal area (P < .001). A significant difference in the occlusal area was found between the two measurement methods (P < .030), whereas no significant differences were found in the marginal gap (P > .350), deep chamfer (P > .719), and axial wall (P > .150). As the 3DSA method is three-dimensional, it allows for the measurement of arbitrary points. CONCLUSION: All of the three fabrication methods are valid for measuring clinical objectives because they produced prostheses within the clinically acceptable range. Furthermore, a three-dimensional superimposition analysis verification method such as the silicone replica technique is also applicable in clinical settings.

OBJECTIVES: Klinefelter syndrome is the most common genetic cause of male infertility and presents with 47, XXY mainly or 46, XX/47, XXY mosaicism. It is characterized by hypogonadism and azoospermia due to testicular failure, however, sporadic cases of natural pregnancies have been reported. With the development of testicular sperm extraction (TESE) and intracytoplasmic sperm injection (ICSI), sperm can be retrieved successfully and ART is applied in these patients for pregnancy. It has been suggested that the risk of chromosome aneuploidy for both sex chromosome and autosome is increased in the sperms from 47, XXY germ cells. Considering the risk for chromosomal aneuploidy in the offspring, preimplantation genetic diagnosis (PGD) could be applied as a safe and more effective treatment option in Klinefelter syndrome. The aim of this study is to assess the outcome of PGD cycles by using FISH for sex chromosome and autosome in patients with Klinefelter syndrome. MATERIALS AND METHODS: From Jan. 2001 to Dec. 2003, PGD was attempted in 8 cases of Klinefelter syndrome but TESE was failed to retrieve sperm in the 3 cases, therefore PGD was performed in 8 cycles of 5 cases (four 47, XXY and one 46, XY/47, XXY mosaicism). In one case, ejaculated sperm was used and in 4 cases, TESE sperm was used for ICSI. After fertilization, blastomere biopsy was performed in 6~10 cell stage embryo and the chromosome aneuploidy was diagnosed by using FISH with CEP probes for chromosome X, Y and 17 or 18. RESULTS: A total of 127 oocytes were retrieved and ICSI was performed in 113 mature oocytes. The fertilization rate was 65.3+/-6.0% (mean+/-SEM) and 76 embryos were obtained. Blastomere biopsy was performed in 61 developing embryos and FISH analysis was successful in 95.1% of the biopsied blastomeres (58/61). The rate of balanced embryos for chromosome X, Y and 17 or 18 was 39.7+/-6.9%. The rate of aneuploidy for sex chromosome (X and Y) was 45.9+/-5.3% and 43.2+/-5.8% for chromosome 17 or 18, respectively. Embryo transfer was performed in all 8 cycles and mean number of transferred embryos was 2.5+/-0.5. In 2 cases, clinical pregnancies were obtained and normal 46, XX and 46, XY karyotypes were confirmed by amniocentesis, respectively. Healthy male and female babies were delivered uneventfully at term. CONCLUSION: The patients with Klinefelter syndrome can benefit from ART with TESE and ICSI. Considering the risk of aneuploidy for both sex chromosome and autosome in the sperms and embryos of Klinefelter syndrome, PGD could be offered as safe and more effective treatment option.

Hajdu-Cheney syndrome (HCS) is a rare skeletal dysplasia that is characterized by acroosteolysis of the distal phalanges, distinctive craniofacial and skull changes, dental abnormalities and generalized osteoporosis. The clinical and radiologic characteristics are variable and these characteristics progress with age. This syndrome shows autosomal dominant inheritance with sporadic cases. The genetic defects or molecular pathogenesis of HCS are still unknown. We experienced a case of Hajdu-Cheney syndrome in a 20-year-old man who had generalized osteoporosis with multiple non-traumatic spine compression fractures. He had acroosteolysis of the hands and feet, wormian bones in the skull, facial dysmorphism (mid-facial flattening, micrognathia and bushy eyebrows), a high arched palate, malocclusion and short dental alveolar processes. HCS was diagnosed based on the clinical and radiologic evidence. For the differential diagnosis, we excluded the other possible causes of the acroosteolysis and wormian bones, including hyperparathyroidism, osteogenesis imperfecta, hypophosphatemia and mandibuloacral dysplasia. The specific treatment of HCS is unknown, but case reports with bisphosphonate treatment have been reported.

PURPOSE: To evaluate the correlation between the conventional method and the clinical history method those determine intraocular lens (IOL) power for cataract surgery in eyes with prior laser in situ keratomileusis (LASIK) in the absence of pre-LASIK data. METHODS: The medical records of 200 eyes in 100 patients who had been treated with LASIK for myopia and were followed up for more than 6 months were reviewed. The IOL powers by conventional method using post-LASIK keratometric value and by clinical history method were compared. RESULTS: The mean values of IOL powers by conventional method, and by clinical history method were +20.00+/-1.48D (+13.74~+23.23D) and +20.79+/-1.28D (+17.27~+24.32D), respectively. The following equation describes the regular relationship between the two METHODS: IOL(CHM) (clinical history method)=0.708*IOL(CM) (conventional method) +6.624 (r=0.816, p<.01). CONCLUSIONS: This equation may offer more accurate IOL power for cataract surgery in eyes with prior LASIK surgery in the absence of pre-LASIK data.

The occurrences of thyrotoxicosis in patients with myasthenia gravis have been reported before the knowledge of the pathogenesis of the two disease. Thytotoxicosis is known to occur in 3 to 6 percent of patients with myasthenia gravis and myasthenia gravis occurs in only a fraction of 1 percent of the thyrotoxic populatian. Myasthenia gravis is currently considered as a systemic autoimmune disorder of acetylcholine receptor and often presented with other autoimmune diseases such as SLE, Rheumatoid arthritis. We experienced a 18-year-old woman who presented with graves disease and isolated ocular myasthenia gravis. Chest CT didnot reveal enlarged thymus. The usual treatement of myasthenia gravis associated with thymtoxicosis consists of medical control of the thyrotoxicosis, then thymectomy and later subtotal thyroidectomy. Her ptosis and thyrotoxicosis have improved after the medicatian of anticholinesterase and propylthiourecil. A case of ocular myasthenia gravis with Gravesdisease was experienced, so we reported the case with a brief review of literature.
