Questionnaire-Based Survey of Diabetes Self-Care Activities and Barriers among Young Korean Adults with Early-Onset Diabetes

Purpose@#Self-management of diabetes is a significant challenge. This study aimed to assess diabetes self-care activities and barriers among Korean young adults with diabetes mellitus. @*Materials and Methods@#This study recruited 209 Korean adults with diabetes, with an onset age of 20–39 years, from four university hospitals. Demographic characteristics and the Summary of Diabetes Self-Care Activities (SDSCA) measure and Diabetes Self-Care Barriers Assessment Scale for Older Adults (DSCB-OA) scores were assessed using questionnaires. @*Results@#The average age of study participants was 32.9±6.1 years. Their self-care activities, including adherence to recommended diabetes medication (5.6±2.4) and number of diabetes pills (5.5±2.3) in the SDSCA measure, were the most well-performed activities among all domains. Responses to inspection of the inside of shoes in the foot care activity (0.8±1.5) and specific exercise sessions in the exercise activity (1.6±1.9) reflected poor levels of compliance. According to the DSCB-OA questionnaire, the mean diabetes self-care barrier of DSCB-OA was 20.6±5.0 of total score 45. The greater perceived barriers to self-care on the DSCB-OA were having difficulty exercising regularly (1.9±0.7) and eating three meals and snacks leading to weight gain (1.9±0.8). @*Conclusion@#Young adults with early-onset diabetes showed a greater barrier to regular exercise and poor compliance with foot care and blood sugar testing. Healthcare providers must strengthen their relationship with young adults with diabetes to provide more education and guidelines for lifestyle modification focused on exercise and to promote higher compliance with diabetic self-care activities for improving clinical outcomes.

Acute Onset Methimazole-Induced Arthralgia and Skin Rash / 대한갑상선학회지

Methimazole, a type of thionamide, is used to treat hyperthyroidism. Several adverse effects of thionamides have been reported. The representative minor adverse effects are arthralgia, skin rash, and gastric intolerance. Methimazole is reported to induce 1-6% of arthralgia cases. These patients begin to suffer from arthralgia from 1 month to 2 years after methimazole treatment. Here, we present a patient with acute onset methimazole-induced arthralgia and skin rash. At 2 days after starting methimazole treatment, a 57-year-old female developed arthralgia and a skin rash on her right leg, which subsequently spread to her left leg and right arm, and she stopped taking the medication. The patient was admitted to the rheumatology department of Ulsan University Hospital, where laboratory tests and a skin biopsy were performed to ascertain whether she had a rheumatic disorder. The skin biopsy revealed nonspecific inflammation. At 2 days after stopping methimazole treatment, the arthralgia and skin rashes had improved and methimazole treatment was recommenced. However, the same symptoms developed within 1 day. Therefore, methimazole treatment was again stopped and the symptoms disappeared.

A Case of Insulinoma with Hypoglycemic Encephalopathy / 임상당뇨병

A 47-year-old male with recurrent abnormal behavior for ten years was referred to our clinic. He was diagnosed with insulinoma and cognitive dysfunction. Persistent hypoglycemia leads to a high risk of cognitive dysfunction in diabetic patients. However, cognitive dysfunction associated with insulinoma is rare. In this case study, cognitive dysfunction was confirmed by neurological testing.

Utility of F-18 FDG-PET in Detecting Primary Aldosteronism in Patients with Bilateral Adrenal Incidentalomas

In patients with primary aldosteronism who have bilateral adrenal incidentalomas, it is important to identify which adrenal gland is secreting excess aldosterone. Traditionally, adrenal vein sampling (AVS) has been performed for lateralization despite its invasiveness. Here we report a case of bilateral adrenal incidentaloma in which 18-Fluorodeoxyglucose (FDG)-positron emission tomography (PET) was used to identify the functional adrenal mass. A 53-yr-old man was referred to our clinic due to bilateral adrenal incidentalomas (right: 1 cm, left: 2.5 cm) on computed tomography (CT). Given his history of colon cancer, FDG-PET/CT scanning was used to rule out metastasis. Although there was focal hot uptake lesion in the right adrenal gland, the patient was suspected primary aldosteronism clinically more than metastasis because of the patient's underlying hypertension with hypokalemia. It was consistent with the results of AVS. Based on these findings, we propose that FDG-PET/CT can be used instead of AVS to identify the source of primary aldosteronism between two bilateral adrenal incidentalomas.

Expression of 4-1BB and 4-1BBL in Graves'Disease / 대한내분비학회지

BACKGROUND: 4-1BB mediated costimulatory signal is a recently identified immunotherapeutic strategy for treating autoimmune diseases without depressing the immune response. In this study, we investigated the expression of 4-1BB and 4-1BBL on the peripheral blood mononuclear cells (PBMC) and we assessed whether the serum levels of soluble (s) 4-1BB and s4-1BBL in the patients with Graves' disease (GD) and compared them with normal subjects. METHODS: Expression of 4-1BB and 4-1BBL on PBMC of GD patients was determined by flow cytometry. The concentrations of s4-1BB and s4-1BBL were assessed in the sera of GD patients by performing ELISA. RESULTS: 4-1BB was constitutively expressed on naive CD4+ and CD8+ T cells of the GD patients and this was increased by stimulation. 4-1BBL was also expressed on the antigen-presenting cells such as CD19+ B cells, monocytes and dendritic cells in GD patients. The serum levels of s4-1BB and s4-1BBL were significantly higher in GD patients than those in controls, and these levels were significantly correlated with the serum levels of thyroid-binding inhibitory immunoglobulin and free T4. CONCLUSION: These results indicate that effector T cells of GD patients can be activated through the 4-1BB-mediated costimulatory signal. Elevated s4-1BB and s4-1BBL levels in the sera of GD patients may affect modulation of the clinical course in GD patients.

Postoperative Findings and Risk for Malignancy in Thyroid Nodules with Cytological Diagnosis of the so-called ‘Follicular Neoplasm’ / 대한내분비외과학회지

PURPOSE: To assess the prevalence and the risk of malignancy in thyroid nodules which were cytologically diagnosed as follicular neoplasm by fine-needle aspiration (FNA) cytology. METHODS: All the patients who had undergone surgery with cytological diagnosis of follicular neoplasm from January 1996 through December 2001 in Asan Medical Center were studied retrospectively. Patients' and nodule characteristics were analyzed for factors associated with the presence of cancer. RESULTS: Two hundreds and fifteen patients (196 females, 19 males) were included and their mean age was 39.4 years (range: 12~76). About half of the patients (102 out of 215, 47.4%) had malignancy with 29 papillary carcinomas, 57 follicular carcinomas, 15 Hürthle cell carcinomas, and 1 medullary carcinoma. Previously suggested factors associated with risk for malignancy such as male gender, large tumor size (>4 cm), or age of patients (>45 years), were not associated with increased risk. Diagnosis of Hürthle cell neoplasia on FNA was also not associated with increased risk. Only the extreme age of the patients (below 20 or above 60 years) was associated with increased risk for malignancy. CONCLUSION: By our hands, prevalence of carcinoma in thyroid nodule patients with cytological diagnosis of follicular neoplasm was much higher than those reported. Clinical characteristics such as male gender, age, and nodule size, are not useful predictors for the presence of malignancy. Thyroid nodules with cytological diagnosis of follicular neoplasm warrant immediate surgery without any further work up.
