Fibrinogen alpha chain (FGA), a subunit of fibrinogen, might be a potential player for type 2 diabetes mellitus (T2DM), since the plasma levels of fibrinogen is known to be related to the incidence of T2DM. To elucidate the potential role of FGA in T2DM, we investigated whether FGA genetic variations are relevant in T2DM in the Korean population. Seven FGA single nucleotide polymorphisms (SNPs) were genotyped in Ansung and Ansan cohorts (474 T2DM subjects and 470 normal controls) in Korea. The association between SNPs and T2DM was determined by logistic regression analysis. Genetic relevance of SNPs to T2DM-related phenotypes was investigated by multiple linear regression analysis. Statistical analysis revealed that among seven FGA SNPs, significant associations with T2DM were observed in FGA rs2070011 (p=0.013-0.034, OR=0.72~ 0.79), rs6050 (p=0.026~0.048, OR=1.24~1.37), and rs2070022 (p=0.016~0.039, OR=0.70~0.72). Two SNPs, rs2070011 and rs6050, also showed significant association with T2DM-related phenotypes such as triglyceride (p=0.005~0.011 for rs2070011 and p=0.003~0.008 for rs6050), total cholesterol (p=0.01 for rs2070011 and p=0.024 for rs6050) and fasting glucose (p=0.035~ 0.036 for rs2070011 and p=0.048 for rs6050) in 470 normal controls. Our association study implies that FGA might be an important genetic factor in T2DM pathogenesis in the Korean population by affecting plasma lipid and glucose levels.

BACKGROUND: Motor conduction slowing in diabetic distal symmetrical polyneuropathy (DSP) generally exceeds that in distal axonal polyneuropathy. Additional mechanisms secondary to axonal injury may contribute towards this slowing. However, clinical and pathophysiological significances of motor conduction slowing have been rarely discussed. The purpose of this study is to evaluate the clinical and pathophysiological significance of conduction slowing in DSP. METHODS: We analyzed motor conduction studies of 39 patients with symptomatic painful DSP and 24 patients with asymptomatic painless DSP. Motor conduction studies of 39 patients with amyotrophic lateral sclerosis (ALS) were used as controls for the amplitude-dependent slowing of conduction. Percentages of normal limits were calculated for the compound muscle action potential amplitude (CMAP), distal motor latency (DL), and conduction velocity (CV), and converted to a square root (SQRT) form. The changes of SQRT-DL or SQRT-CV according to SQRT-CMAP changes were plotted and analyzed. RESULTS: Regression analysis showed that DL and CV were amplitude-dependent in both painless DSP and ALS. The changes of DL and CV in painful DSP did not show amplitude-dependency except DL in the lower extremities. CONCLUSIONS: This data supports the hypothesis that the mechanism of slowing is similar in both painless DSP and ALS and results from the loss of large, fast-conducting fibers. Lack of amplitude-dependency of conduction slowing in painful DSP may reflect the combined axonal and demyelinating changes, possibly due to inflammation.

OBJECTIVES: Idiopathic REM sleep behavior disorder (RBD) is by far the strongest clinical predictor of neurodegenerative disease available. Several potential early diagnostic markers of neurodegenerative disease including autonomic symptoms have been proposed, but they have generally not been tested in presymptomatic neurodegenerative disease. So the authors investigated autonomic symptoms and their associated factors in idiopathic RBD patients. METHODS: 52 idiopathic RBD patients and 52 controls participated in the study. Autonomic symptoms were evaluated by applying the unified multiple system atrophy rating scale (UMSARS) and measuring orthostatic systolic blood pressure drop. RESULTS: Idiopathic RBD patients showed significantly higher UMSARS subscale scores and sharper drop of orthostatic systolic blood pressure than controls. In multiple linear regression analysis, all autonomic symptoms and measured orthostatic systolic blood pressure drop were associated with RBD. In addition, orthostatic symptoms were associated with medication and age, urinary function was associated with benign prostatic hyperplasia, and measured orthostatic systolic blood pressure drop was associated with hypertension. CONCLUSION: In this study, idiopathic RBD patients showed more autonomic symptoms than controls. However, other autonomic symptoms-related factors also influenced some autonomic symptoms. Prospective studies should be performed to evaluate autonomic symptoms as a potential predictor of neurodegenerative diseases.

Cyclin D1, a cell cycle regulator essential for G1 phase progression, is a candidate proto-oncogene implicated in pathogenesis of several human carcinomas including breast carcinoma. We studied the cyclin D1 expression in 101 cases of primary breast carcinoma tissues. The overexpression of cyclin D1 was immunohistochemically demonstrated in 34 (37.8%) of 90 cases of invasive breast carcinoma. Positive cyclin D1 staining was seen in 32 of 79 invasive ductal carcinomas, and 2 of 3 mucinous carcinomas. All 5 medullary carcinomas, 2 invasive lobular carcinomas, and 1 metaplastic carcinoma were negative. Cyclin D1 overexpression was observed in 9 of 11 ductal carcinoma in situ (DCIS). Normal epithelial components, either ductal or lobular, were not immunoreactive for cyclin D1. No significant correlations were observed between cyclin D1 immunoreactivity and other parameters including tumor size, clinical stage, nuclear or histologic grades, lymphatic or angioinvasion, lymph node metastasis, and immunohistochemical status of progesterone receptor, p53 and c-erbB-2. The overexpression of cyclin D1 was positively correlated with estrogen receptor status (p=0.025). Based on our results, the cyclin D1 protein aberration may play a role in tumorigenesis of breast carcinoma, but does not seem to have prognostic value in invasive breast carcinoma without hormonal treatment.

Acute limb compartment syndrome (ALCS) is defined as compound symptoms resulting from poor oxygenation and decreased nutrition supply to muscles and nerves in a tightly confined compartment. The most common cause of ALCS is tibia fracture, followed by blunt trauma to soft tissue. However, non-traumatic causes are rare. We report an iatrogenic, non-traumatic ALCS case after venoarterial extracorporeal membrane oxygen (VA-ECMO) therapy. A 14-year-old male received VA-ECMO therapy due to cardiorespiratory failure after drowning. Although he had no symptoms during therapy, leg swelling appeared 10 hours after ECMO treatment. Two days after the leg swelling, the patient underwent a fasciotomy. Unfortunately, nerve conduction studies and electromyography showed multiple neuropathies in the lower leg. Despite 2 weeks of rehabilitation with electrical stimulation, an exercise program, and physical therapy, there was no definite change in muscle strength. To our knowledge, this is the first reported case of non-traumatic ALCS after VA-ECMO therapy in Korea.

Subacute necrotizing lymphadenitis was first reported by Kikuchi and Fujimoto in 1972. Young females no more than 30 years of age are mainly affected. It usually manifests as fever and cervical lymphadenopathy. We experienced three cases of subacute necrotizing lymphadenitis in an 11-year-old boy, a 12- year-old boy and an 11-year-old girl. Symptoms presented were URI signs, diarrhea, headache and weight loss along with fever and cervical lymphadenopathy. Fever persisted from 9 to 30 days and did not respond to antibiotics. We performed aspiration biopsy of cervical lymph node which was consistent with subacute necrotizing lymphadenitis in all cases. We used oral steroid in one case. Fever and lymphadenopathy subsided spontaneously within one month. There were no other complications.

BACKGROUND AND OBJECTIVES: Ten to twenty percent of children with Kawasaki disease (KD) do not respond to initial intravenous immunoglobulin (IVIG) treatment. If untreated, approximately 15% to 25% of KD patients have complications. The aim of this study was to find useful predictors of responsiveness to initial IVIG treatment in KD. SUBJECTS AND METHODS: We retrospectively reviewed medical records of 91 children diagnosed with KD at Myong Ji Hospital from March 2012 to April 2014. Before and after (24 hours to 36 hours) IVIG treatment, the following laboratory data were obtained: hemoglobin (Hb) level, white blood cell count, proportion of neutrophil, lymphocyte and eosinophil, platelet count, erythrocyte sedimentation rate (ERS), C-reactive protein (CRP), creatine kinase (CK), creatine kinase MB (CK-MB), and N-terminal pro-brain natriuretic peptide (NT-proBNP). Subjects were then divided into two groups: IVIG-responsive or IVIG-resistant. RESULTS: Of 91 patients, 11 (12%) required retreatment. By univariate analysis, before-IVIG laboratory parameters of white blood cell count, % neutrophil, ERS, CRP, sodium, CK, CK-MB, and NT-proBNP were significantly different between IVIG-responsive and IVIG-resistant patient groups. In the after-IVIG laboratory parameters, Hb level, white blood cell count, % neutrophil, % lymphocyte, CRP, CK, CK-MB, and NT-pro-BNP were significantly different between the two groups. While the mean-differences were not statistically significant, fractional change (FC)-CRP and FC-% neutrophil showed significant difference. By multivariate analysis, FC-CRP was confirmed to be an independent predictor for initial IVIG resistance. CONCLUSION: Fractional change-C-reactive protein might be a useful and important value for predicting initial IVIG resistance in KD patients.

Maternal and child health is an important issue throughout the world. Given their impact on maternal and child health, nutritional issues need to be carefully addressed. Accordingly, the effect of maternal, child, and nutritional disorders on disability-adjusted life years (DALYs) should be calculated. The present study used DALYs to estimate the burden of disease of maternal, neonatal, and nutritional disorders in the Korean population in 2012. For this purpose, we used claim data of the Korean National Health Insurance Service, DisMod II, and death data of the Statistics Korea and adhered to incidence-based DALY estimation methodology. The total DALYs per 100,000 population were 376 in maternal disorders, 64 in neonatal disorders, and 58 in nutritional deficiencies. The leading causes of DALYs were abortion in maternal disorders, preterm birth complications in neonatal disorders, and iron-deficiency anemia in nutritional deficiencies. Our findings shed light on the considerable burden of maternal, neonatal, and nutritional conditions, emphasizing the need for health care policies that can reduce morbidity and mortality.
