Granuloma annulare (GA) is a common non-infectious granulomatous disease. Generalized GA is the second most common variant of GA. It is often associated with recalcitrant disease progression despite treatment. The lesion of generalized GA typically presents widespread papules that coalesce to form annular plaques over the whole body. We report a case of a patient with disseminated papules and coalescing annular plaques, primarily involving the intertriginous area and mimicking tinea corporis or cruris. Histopathological findings confirmed the lesion as GA. This case underscored the unusual clinical presentation of generalized GA. A case of GA localized to the intertriginous area has rarely been reported. Given the recalcitrant nature of the disease, dermatologists should consider generalized GA as a differential diagnosis in patients with an annular lesion involving the intertriginous area. Thus, we report this as an atypical case of generalized GA localized to the intertriginous area. (Korean J Dermatol 2021;59(10):797∼800)

Gallium Oxide (Ga₂O₃) is preferred as a material for next generation power semiconductors. The Ga₂O₃ should solve the disadvantages of low thermal resistance characteristics and difficulty in forming an inversion layer through p-type ion implantation. However, Ga₂O₃ is difficult to inject p-type ions, so it is being studied in a heterojunction structure using p-type oxides, such as NiO, SnO, and Cu₂O. Research the lateral-type FET structure of NiO/Ga₂O₃ heterojunction under the Gate contact using the Sentaurus TCAD simulation. At this time, the VG-ID and VD-ID curves were identified by the thickness of the Epi-region (channel) and the doping concentration of NiO of 1 × 10¹⁷ to 1 × 10¹⁹ cm^-3. The increase in Epi region thickness has a lower threshold voltage from -4.4 V to -9.3 V at I_D = 1 × 10^-8 mA/mm, as current does not flow only when the depletion of the PN junction extends to the Epi/Sub interface. As an increase of NiO doping concentration, increases the depletion area in Ga₂O₃ region and a high electric field distribution on PN junction, and thus the breakdown voltage increases from 512 V to 636 V at I_D =1 × 10^-3 A/mm.

Previously, Gum Metal (Ti-24(Nb + Ta + V)-(Zr, Hf)-O (at%)) exhibiting an ultralow Young`s modulus, ultrahigh strength and super elasticity was developed by Saito et al., who proposed that three electronic magic numbers, an average electron/atom (e/a) ratio of 4.24, an average bond order (Bo) of about 2.87, and an average “d” electron-orbital energy level (Md) of about 2.45 eV, should be satisfied simultaneously to obtain such “super” properties. The purpose of this study was to find new alloy systems possessing those properties and to examine the effect of beta equivalent content ([Mo]eq) on Young`s moduli of new alloys having the same three electronic numbers mentioned above. It was found that not only three electronic numbers but also [Mo]eq should be considered to obtain a similar Young`s modulus and hardness with respect to the Gum Metal.

Background: The number of elderly patients with end-stage kidney disease has been increasing, but the outcomes of kidney transplants (KT) remain poorly understood in elderly patients. Therefore, we evaluated the clinical outcomes of elderly KT recipients and analyzed the impact of elderly donors. Methods: This retrospective cohort study included patients who underwent KT between 2000 and 2019. KT recipients were divided into four groups according to a combination of recipient and donor age (≥60 or <60 years); elderly recipients: old-to-old (n = 46) and young-to-old (n = 83); young recipients: old-to-young (n = 98) and young-to-young (n = 796). We compared the risks of mortality, graft failure, and acute rejection between groups using Cox regression analysis. Results: The incidence of delayed graft function, graft failure, and acute rejection was not different among groups. Annual mean tacrolimus trough level was not lower in elderly recipients than young recipients during 10-year follow-up. Mortality was significantly higher in elderly recipients (p = 0.001), particularly infection-related mortality (p < 0.001). In multivariable Cox regression analysis, old-toold and young-to-old groups had increased risk of mortality (adjusted hazard ratio [aHR], 2.89; 95% confidence interval [CI], 1.14– 7.32; p = 0.03; aHR, 3.06; 95% CI, 1.51–6.20; p = 0.002). However, graft failure and acute rejection risks were not increased in elderly recipients. Conclusion: In elderly recipients, graft survival and acute rejection-free survival were not inferior to those of young recipients. However, mortality, especially risk of infection-related death, was increased in elderly recipients. Thus, low immunosuppression intensity might help decrease mortality in elderly recipients.

Diabetic muscle infarction (DMI) is a rare complication that usually occurs in patients with longstanding microvascular complications of diabetes. The typical clinical presentation of DMI includes a sudden onset of pain, tenderness, and swelling of the lower limbs. DMI can be diagnosed by typical clinical manifestations and magnetic resonance imaging (MRI). Treatment usually includes immobilization of the affected extremity and taking analgesics. A 44 year-old woman with type 2 diabetes mellitus and Hashimoto's thyroiditis for 10 years, presented with an abrupt and spontaneous onset of severe pain in the left thigh. In order to evaluate the etiology, angio-computed tomography, bone scan, and MRI of the lower extremities were performed. DMI was diagnosed based on the hyper-intense T2 weighted signals on the MRI. The patient was fully recovered with the conservative treatment.

The purposes of this study were to investigate the quality (structure and process) of home-based day care and center-based day care, and to examine socioemotional development among infants who were in both types of day care. The subjects of this study were 101 infants who were in home-based day care and 181 infants who were in center-based day care. The measurements were socio-emotional development scale and assessment scales for day care programs. Results indicated that, first, home-based day care did not significantly differ from center-based day care in terms of structure. Second, home-based day care were, to some degree, significantly different from center-based day care in the process: home-based day care had better play environment and play activities than did center-based day care. Lastly, there were significant differences in socio-emotional development among infants according to the type of day care: infants in home-based day care were more independent to their teacher and felt more secure in child care homes than was true for the infants in center-based day care.

The present study was conducted to investigate the prevalence, biochemical properties and plasmid profiles of Salmonella organisms isolated from wild birds in Daegu area during the period from May, 1999 to August, 2000. Twenty strains of Salmonella were identified from 192 samples of heron feces and 86 samples of pigeon feces. Among Salmonella isolates, S. montevideo were the most frequent serotype (16 strains), 3 strains of them were S. typhimurium and the other one was untypable. The biochemical properties of 20 strains of Salmonella isolated were in accordance with the traditional characteristics of Salmonella spp. in the majority of biochemical test such as IMViC, carbohydrate fermentation and amino acid decarboxylation. The majority of isolates were highly susceptible to amikacin, ampicillin, amoxicillin, carbenicillin, cephalothin, ciprofloxacine, chloramphenicol, enrofloxacin, furazolidone, gentamicin, kanamycin, nalidixic acid, polymixin B and sulfamethoxazole, while they were moderately susceptible to streptomycin and tetracyclin. However, the majority of them were highly resistant to nitrofurantoin. In plasmid profile, 21.1 kilobase (Kb), 20 Kb and 13.2 Kb fractions were common to three S. tvphimurium and one untypable strains, and no fraction was shown in all strains of S. montevideo.
