RESUMEN
Background@#The importance of digital technology is increasing among older adults. In this study, the digital health technology utilization status, purpose, and satisfaction of older adults were investigated according to frailty. @*Methods@#A face-to-face survey was conducted among adults aged 65 years or older. Frailty was defined using the Korean version of the fatigue, resistance, ambulation, illnesses, and loss of weight scale. @*Results@#A total of 505 participants completed the survey, with 153 (30.3%) identified as pre-frail or frail and 352 (69.7%) as healthy. All respondents used smartphones; 440 (87.1%) were application users, and 290 (57.4%) were healthcare application users. Wearable devices were used by only 36 patients (7.1%). Pre-frail or frail respondents used social media more frequently than healthy respondents (19.4% vs. 7.4%, P < 0.001). Among the respondents, 319 (63.2%) were not able to install or delete the application themselves, and 277 (54.9%) stated that the application was recommended by their children (or partner). Pre-frail and frail respondents used more healthcare applications to obtain health information (P = 0.002) and were less satisfied with wearable devices (P = 0.02). @*Conclusion@#The usage rate of digital devices, including mobile phones among older adults in Korea is high, whereas that of wearable devices is low. There was a notable difference in the services used by pre-frail and frail respondents compared to healthy respondents. Therefore, when developing digital devices for pre-frail and frail older adults, it is crucial to incorporate customized services that meet their unique needs, particularly those services that they frequently use.
RESUMEN
PURPOSE: The aim of the present study was to investigate the role of polymorphic cytosine adenine (CA) repeat of the IGF-I gene in the age-related alterations of serum IGF-I levels in healthy children. METHODS: Two hundred and forty three normal healthy children (136 boys; 107 girls) aged between 7 and 15 years were enrolled in the present study. The primers were designed to cover the promoter regions containing the polymorphic CA repeat. Data were analyzed using GeneMapper software, version 3.7. All analyses were performed using MEDCALC software packages. RESULTS: Deletion of 2 bp (G, A) following 3' of CA repeat were observed in all Korean children. The CA repeat sequences ranged from 17 to 23, and 19 CA repeat were the most common with an alleles frequency of 39.3 percent. Considering genotypes, 63.8 percent of subjects were homozygote or heterozygote for 19 CA repeat (192 bp allele), suggesting that this is wild type allele from which all other alleles originated in Korean children. Homozygote for 19 CA repeat were 14.7 percent, heterozygote for 19 CA repeat was 49.1 percent and 19 CA noncarriers totalled 36.2 percent. In 19 CA repeat noncarriers, the mean height, weight and serum IGF-I level were lower compared with those of 19 CA homozygous carriers, but statistically not significant. Correlations between serum IGF-I level and age according to the IGF-I genotypes revealed statistically significant relationships in the all groups, in the 19 CA repeat carrier group and, even in the noncarrier group. CONCLUSIONS:There were no significant differences of the mean height, weight and serum IGF-I levels among three different genotype groups. Also, there were no significantly different correlations between 19 CA repeat polymorphisms and serum IGF-I levels, according to genotype. Our results suggest that the IGF-I 19 CA repeat gene polymorphism is not associated with circulating IGF-I levels in healthy children.

Tuberous sclerosis is an autosomal dominant disorder of cellular differentiation that affect the brain, skin, heart, kidney and other organs. We experienced three cases of tuberous sclerosis that affect multiple organs in mother and two daughters. We report these cases with brief review and related literatures.

Subcutaneous panniculitic T-cell lymphoma is one of very rare diseases in children, which is presumably derived from various immunocompetent T-cell system components. It is a distinctive clinicopathologic entity, different from other lymphoma group. We report a case of subcutaneous panniculitic T-cell lymphoma in a 14-year-old boy with the complaints of fever and multiple subcutaneous nodule. A brief review of related literatures was also made.

PURPOSE: Of the cancers in childhood, leukemia is the most frequent one. For the desirable control of childhood leukemia, the basic data for the incidence has a great importance. The authors made a report about the incidence of leukemia in childhood, which analyzed the data from 126 cases in Kyongnam province, Korea, during 1991~1995. METHODS: The data were obtained from 126 new cases of childhood leukemia who had been living in the Kyongnam province and were diagnosed at the 26 university hospitals or general hospitals in the Kyongnam area and other cities from 1991 to 1995. RESULTS: The age-and-sex adjusted annual incidence rate per 100,000 population during 1991~1995 varied from 1.82 to 2.86, and cumulative annual incidence rate was 2.41 (male 2.26 and female 2.57 respectively). Male to female sex ratio was 1:1 in total cases. By the major types of childhood leukemia, the cases were composed of acute lymphocytic leukemia 70.6%, acute myelocytic leukemia 26.9% and chronic myelocytic leukemia 2.5%. The cumulative annual incidence rate per 100,000 population (crude rate) during 1991~1995 were 2.77 in Ulsan city, 2.62 in Chinju city and 2.34 in the whole area of Kyongnam province. CONCLUSION: It was concluded that the age-and-sex adjusted annual incidence rate per 100,000 of childhood in Kyongnam province was 2.41, which was lower than that in Pusan city in the same period. And, there was no significant difference of the cumulative annual incidence rate between Ulsan area and Chinju area in the same period.
