We describe two cases of right hyperglycemia hemichorea (HGHC) with identical Tc-99m TRODAT-1/ Tc-99m ECD scan findings. While the brain MRI showed signal alterations within the left putamen, there was evidence of hyperperfusion on Tc-99m TRODAT-1 but hypoperfusion on Tc-99m ECD within the left putamen, in association with hyperperfusion within left thalamus on Tc-99m ECD. The discrepancy between the Tc-99m TRODAT-1 and Tc-99m ECD scan provides insight into the imbalance between direct and indirect circuits along the nigrostriatal pathway, as the fundamental genesis of HGHC. Furthermore, the hyperperfusion at the left thalamus represents thalamic disinhibition secondary to loss of pallidal negative control, which ultimately leads to HGHC through re-entrant outflow to the motor cortex.

Objective To investigate the cause，pathogenesis，clinical manifestations，treatment，and prognosis of secondary hemichorea based on related clinical features and examinations by summarizing the medical records of 25 patients with secondary hemichorea-hemiballism. Methods An analysis was performed for 25 patients with hemichorea-hemiballism who were admitted and treated from July 2018 to April 2024，including general status，clinical features，laboratory examinations，MRI or CT examination，treatment methods，and prognosis. Results Of all 25 patients，11 （44.0%） had acute cerebrovascular diseases [including 7 cases （28.0%） of cerebral infarction，3 cases （12.0%） of cerebral hemorrhage，and 1 case （4.0%） of moyamoya disease]，13 （44.0%） had hyperglycemia，and 1 had unknown causes. Of all 25 patients with hemichorea-hemiballism after treatment of the primary disease and symptomatic treatment，18 patients had significant improvements in hemichorea symptoms，and 7 had disappearance of hemichorea symptoms. One patient experienced recurrence after half a year due to self-withdrawal of medication，and the other patients took medication regularly，with no recurrence at follow-up half a year later.Conclusion Hemichorea-hemiballism is more common in the elderly，and acute cerebrovascular disease is the most common cause of hemichorea-hemiballism，followed by hyperglycemia，with the basal ganglia as the main lesion site. In addition to the treatment of the primary disease，symptomatic treatment with haloperidol，clonazepam，or risperidone can significantly improve clinical symptoms and help to achieve a good prognosis.

Pheochromocytoma is usually associated with a combination of various clinical manifestations caused by the overproduction of catecholamines. It is frequently accompanied by impaired glucose tolerance operating through 2-and-adrenergic mechanisms. A 41-year-old-woman was admitted to the hospital because of poorly-controlled diabetes mellitus and hypertension. She had suffered intermittent paroxysmal attacks of headache and chest discomfort and had been treated intermittently over a 2 year period for diabetes mellitus and hypertension. At admission, the levels of serum epinephrine, norepinephrine urinary excretion of total metanephrine, and VMA were all abnormally elevated. Adrenal CT showed a well-defined, homogenous mass in the right adrenal region and the tumor was diagnosed as pheochromocytoma. After tumor resection, the increased blood level of catecholamines, the urinary excretion of total metanephrine, and VMA were normalized, as was the hyperglycemia state. Diabetes mellitus of the patient was considered permanently resolved after tumor removal by the result of glucose tolerance in 75g oral glucose tolerance test.

The prevalence of obesity in Korean children is estimated to be around 10%, and has increased significantly over the past 20 years. Metabolic syndrome, which includes central obesity, glucose intolerance, insulin resistance, dyslipidemia, and hypertension, is a well documented risk factor for cardiovascular diseases, but there is no general consensus concerning its definition for children. In this study, ablut 30-40% of overweight or obese children had metabolic syndrome compared to less than 10% in the general population. Dyslipidemia was the most common component and hyperglycemia was the least common component of metabolic syndrome. If the prevalence of childhood obesity continues to increase, it is highly likely that the prevalence of the metabolic syndrome will also increase. These findings emphasize the importance of preventing obesity in addition to the diagnosis and management of metabolic syndrome in Korean adolescents.

The clustering of insulin resistance with hypertension, glucose intolerance, hyperinsulinemia, increased triglyceride and decreased HDL cholesterol levels, and central and overall obesity has been called syndrome X, or the insulin resistance syndrome(IRS). To develop a nutrition service for IRS, this study was performed to evaluate the prevalence of each component of the metabolic abnormalities of IRS and analyze the clustering pattern of IRS among subjects living in the Taegu community. Participants in this study were 9234(mean age ; M/F 48/40yrs);63.5% were men, 24.4% were obese, 13.3% had hypertension. 3.7% had hyperglycemia, and 32.4% had hyperlipidemia. The IRS was defined as the coexistence of two or more components among metabolic abnormalities; obesity, hypertension. hyperglucemia and hyperlipidemia. The prevalence of IRS in Taegu was 19.2%(M/F:20.8%/16.4%), the clustering of these fisk variables was higher in advanced age group. Among the subjects of IRS having two of more diseases, 75.6% were obese, the pattern were similar in men and women. The younger, the higher the prevalence of obesity associated clustering patterns. The prevalence of obesity associated patterns among the hyperglycemia associated clustering patterns was 44.5%. The samples of the representative clustering patterns were obesity and hyperlipidemia (8.0%), hypertension and hyperlipidemia(3.2%), hypertension, obesity and hyperlipiemia(3.1%), hypertension and obesity(2.3%), and hyperglycemia and hyperlipidemia(0.8%). The clustering of obesity and hyperlipidemia until 50 year old groups, and the clustering of hypertension and hyperlipidemia in the 60 and 70 age groups were the most prevalent. We concluded that insulin resistance syndrome was a relatively common disorder in the Taegu community, and prevalence and the characteristics of the intervention strategies for IRS are desired, an effective improvement will be achieved.

Introduction: Adiponectin is an adipocytokine known to have anti-inflammatory and anti-atherogenic effects. It appears to impact insulin resistance and the subsequent development of type 2 diabetes mellitus (T2D). The gene encoding adiponectin ADIPOQ, has single nucleotide polymorphisms (SNPs) that can be useful biomarkers to predict development of T2D; with the T/G polymorphism of SNP +45 in exon 2 being the most common. Objective: This study was conducted to evaluate the association of T45G adiponectin gene polymorphism with hyperglycemia among adult Filipinos seen at the outpatient department of the Philippine General Hospital. Methods: This is a matched case-control study, with duration of 12 months. DNA was extracted using the QIAGEN MIDI Blood Extraction Kit. The genomic DNA obtained was then subjected to real time PCR for SNP detection. Results: One hundred (100) adults were enrolled; forty-three (43) had normoglycemia, while fifty seven (57) had hyperglycemia, after a 75-g oral glucose tolerance test. Hyperglycemic subjects were older (44±15.6 years vs. 52±8.3 years, p-value 0.002), and had lower HDL levels (58.5±16.0 mg/dLvs. 47.8+11.8 mg/dL, p-value 0.000). Among thirty-nine (39) participants found to have the T45G adiponectin gene polymorphism, 22 or 56.4% were hyperglycemic while 17 or 43.6% were normoglycemic. Conclusion There was no significant association observed between the T45G SNP and presence of hyperglycemia.

BACKGROUND: Acute postprandial hyperglycemia is an important affector for atherosclerosis in subjects with glucose intolerance. We analyzed the relationship of brachial-ankle pulse wave velocity (baPWV) with fasting and post-challenge plasma glucose levels according to different time points during oral glucose tolerance test (OGTT). METHODS: In 663 subjects with fasting hyperglycemia, 75 g OGTT were performed to confirm the glucose tolerant status, and fasting, post-challenge 30-minute and 120-minute glucose levels were measured. Anthropometric measurements were done, and fasting lipid profiles were measured. baPWV were measured in all subjects and the relationship between fasting, 30- and 120-minute post-challenge glucose levels and baPWV were analyzed. RESULTS: Among the participants, 62.9% were prediabetes and 31.7% were diabetes. Mean baPWV value was significantly higher in subjects with diabetes compared with prediabetes group. In bivariate correlation analyses, age, blood pressure, total cholesterol, low density lipoprotein cholesterol, 30-minute and 120-minute post-challenge glucose levels showed significant positive correlation with baPWV value. In multiple regression analysis, 30-minute post-challenge glucose level was a weak but significant determinant for mean baPWV value even after adjustment for other confounding variables. CONCLUSIONS: Postprandial hyperglycemia, especially 30-minute glucose levels showed significant correlation with baPWV in subjects with fasting hyperglycemia. These results can imply the deleterious effect of acute hyperglycemic excursion on arterial stiffness in subjects with glucose intolerance.
