This report presents the case of a 49-year-old man who presented with giant masses that had recently grown on the bilateral sides of the tongue. A clinical examination revealed rubbery yellowish lesions protruding from the tongue.A panoramic radiograph showed an enlarged soft tissue shadow of the tongue. Computed tomography showed well-defined circumscribed mass exhibiting a homogeneous low density on the bilateral sides of the tongue. On magnetic resonance images, the masses showed a high signal intensity on T1-weighted images and iso-signal intensity with partially hyperintense margin on fat-suppressed T2-weighted images. Surgical excision was performed, and a histopathologic examination confirmed the diagnosis of lipoma. The patient recovered well with no sign ofrecurrence. A giant lipoma is defined as a lipoma larger than 5 cm in diameter. A literature review of giant lipomas of the tongue is also presented herein.

The aim of this study was to investigate the relationship between retirement preparation and depressive symptoms among Koreans 50 years of age or older. We used data from the 2009 to 2013 Korean Retirement and Income Panel Study (KReIS), which included data from the 365 baseline participants of 50 years of age or older. Our sample included only newly retired participants who worked in 2009, but had retired in the 2011 and 2013. To monitor the change in depressive symptoms according to retirement preparation, we used repeated measurement data. We measured depressive symptoms using the Center for Epidemiological Studies Depression (CES-D) 20-item scale. In addition, we measured retirement preparation using a single self-report question asking whether the participant was financially ready for retirement. We evaluated relationship between retirement preparation and depressive symptoms after multivariable adjustment. Compared to subjects who had prepared for retirement (reference group), participants who had not prepared for retirement had increased depression scores (β = 2.49, P < 0.001). In addition, individuals who had not prepared for retirement and who had low household income had the highest increase in depression scores (β = 4.43, P < 0.001). Individuals, who had not prepared for retirement and without a national pension showed a considerable increase in depression scores (β = 3.02, P < 0.001). It is suggested that guaranteed retirement preparation is especially important for mental health of retired elderly individuals with low economic strata.

A 16-year-old male presented with pain in the right posterior mandible on chewing that had lasted for several months. The radiographic features of the lesion included a radiolucent-radiopaque mixed-density mass with a radiolucent rim attached to the root of the mandibular right first molar. The preliminary radiographic diagnosis was benign cementoblastoma, which was confirmed by histopathological examination following surgical excision. The lesion recurred 3 years after treatment; radiographically, it consisted of 3 round foci with mixed radiopacity, each with a radiolucent rim near the root of the mandibular right second premolar and the edentulous postoperative region. The lesion was diagnosed as recurrent benign cementoblastoma and a second surgery was scheduled. This report presented an unusual case of recurrent benign cementoblastoma following surgical excision and extraction of the involved tooth, along with a literature review on reported cases of recurrent benign cementoblastoma with a focus on its clinical features and the best treatment options.

BACKGROUND/AIMS: Although there is growing interest in hospice-palliative care, little information is available on the effects of such care in South Korea. Addressing this research gap, i.e., determining the cost-effectiveness of hospice-palliative care in South Korea, will help guide policy. Thus, the aim of this study was to evaluate the cost-effectiveness analysis of hospice-palliative care in adults diagnosed with terminal cancer. METHODS: We used a Markov model to construct a decision tree, for an analysis comparing the general ward with the hospice-palliative ward in terms of patient quality of life and cost-effectiveness. Cost and quality of life were estimated based on published Korean studies. Cost-effectiveness was calculated as the incremental cost relative to the incremental effect. Additionally, a one-way sensitivity analysis was performed to test the robustness of the results. RESULTS: Hospice-palliative ward care was more cost-effective than general ward care. The incremental cost was 290,401 Korean won (KRW) and the incremental effect was −0.25. The incremental cost-effectiveness ratio was −1,174,045 KRW. A similar pattern of results was obtained in the sensitivity analysis. CONCLUSIONS: Our results suggest that hospice-palliative ward care is more cost-effective than general ward care.

Acute isolated vestibulopathy could be caused by either viral inflammation or ischemia. However, diagnosing ischemic vestibulopathy is difficult due to the ambiguity of the causal relationship between ischemia and peripheral vestibulopathy. We present here a patient with acute ischemic vestibulopathy without hearing loss caused by internal auditory artery occlusion, indirectly proven by the finding of a simultaneously developed silent cerebellar infarction. The details of this case suggest that patients with acute isolated peripheral vestibulopathy should be carefully evaluated for underlying causes, including vascular risk factors.

The vibrational spectral differences of normal and lung cancer cells were studied for the development of effective cancer cell screening by means of attenuated total reflection infrared spectroscopy. The phosphate monoester symmetric stretching nus(PO3(2-)) band intensity at ~970 cm-1 and the phosphodiester symmetric stretching nus(PO2-) band intensity at ~1,085 cm-1 in nucleic acids and phospholipids appeared to be significantly strengthened in lung cancer cells with respect to the other vibrational bands compared to normal cells. This finding suggests that more extensive phosphorylation occur in cancer cells. These results demonstrate that lung cancer cells may be prescreened using infrared spectroscopy tools.

Hyponatremia and hyperkalemia in infancy can be attributed to various causes, originating from a variety of renal and genetic disorders. Pseudohypoaldosteronism type 1 (PHA1) is one of these disorders, causing mineralocorticoid resistance that results in urinary salt wasting, failure to thrive, metabolic acidosis, and dehydration. PHA1 is heterogeneous in etiology. Inactivating mutations in the NR3C2 gene (4q31.1), which encodes the mineralocorticoid receptor, causes a less severe autosomal dominant form that is restricted to the kidney, while mutations in the amiloride-sensitive epithelial sodium channel gene (alpha subunit=SCNN1A, 12p13; beta subunit=SCNN1b, 16p12.2-p12.1; gamma subunit=SCNN1G, 16p12) causes a more severe autosomal recessive form, which has systemic effects. Here we report a neonatal case of kidney restricted PHA1 (renal type of PHA1) who first showed laboratory abnormalities before obvious PHA1 manifestations, with two functional polymorphisms in the NR3C2 gene. This is the second genetically confirmed case in Korea and the first to show functional polymorphisms that have previously been reported in the literature.

Background/Aims: Point mutations in the 23S ribosomal RNA gene have been associated with Helicobacter pylori clarithromycin resistance. This study aimed to detect the prevalence of these point mutations and to investigate the role of different point mutations in the success of eradication therapy. Methods: We retrospectively investigated a total of 464 consecutive patients who underwent an endoscopic examination and dual-priming oligonucleotide-based multiplex polymerase chain reaction for H. pylori between June 2014 and October 2019. For 289 patients with negative point mutations, standard triple therapy was used in 287 patients, and the bismuth-quadruple regimen was used in two patients. For 175 patients with positive point mutations (A2142G, A2143G, and both mutations), standard triple and bismuth-quadruple therapies were used in 37 patients and 138 patients, respectively. Results: The eradication rates of standard triple and bismuth-quadruple therapies showed no significant difference in mutation-negative patients or those with the A2142G point mutation.However, the eradication rate with bismuth-quadruple therapy was significantly higher than that with standard triple therapy in the group with the A2143G mutation or with the double mutation.The eradication rates for standard triple and bismuth-quadruple therapies, respectively, were 25.8% and 92.1% in the per-protocol group (p<0.001) and 24.2% and 85.2% in the intention-totreat analysis (p<0.001). Conclusions The A2143G point mutation is the most prevalent cause of clarithromycin resistance. Bismuth-quadruple therapy is superior to standard triple therapy in patients with the A2143G or double point mutation.
