Adult polycystic kidney disease is a genetic disease characterized by bilateral multiple renal cysts and is transmitted as an autosomal dominant traits. The disease usually manifests in the fourth decade of life. The affected patients usually die with end stage renal failure, cardiovascular assaults and infection etc. Cardiovascular assaults include ruptured berry aneurysm, spontaneous intracranial hemorrhage, acute myocardial infarction, dissecting aortic aneurysm and hypertensive heart failure. Fatal intracranial hemorrhage and hypertensive heart failure occur in 15% and 2% of patients, respectively. Genetically-determined structural weakness in the arterial wall have been suggested as a possible factor in the genesis of berry aneurysm. We have experienced three autopsy cases with cardiovascular causes of sudden death. Two cases have intracranial hemorrhage (1 berry aneurysm and 1 intracerebral hemorrhage) and the remaining one is dead with hypertensive cardiomyopathy. All of them are aged over 40 years and associated with polycystic liver disease. Histologically, myriad cysts of enlarged bilateral kidney are lined by single layer of cuboidal cells with focal hyperplastic epithelial configuration. Diffusely scattered liver cysts are also lined by flat to cuboidal epithelium and often associated with portal fibrosis.

Background: Some epidemiological studies have indicated that weather and air pollution can cause
adverse health conditions and that these effects can exhibit regional variation. The prevalence of
headache is so high and it is a common cause of morbidity. Therefore, this study evaluated whether
weather and air pollution were associated with the prevalence of headaches. Methods: A symmetric
bidirectional case-crossover design was applied, using conditional logistic regression models to determine
the association between headaches and weather and air pollution. From January 2006 to August 2007,
a total of 245 patients with headaches were recruited. Headache subtypes were classifi ed as migraine,
tension-type headaches, and others. Meteorological data (average temperature and relative humidity)
and values related to air pollutants (CO, NO2
, O3
, SO2
, and particulate matter with an aerodynamic
diameter of less than 10 μm) were obtained. Results: Higher average temperatures were associated with
the total number of headaches (hazard ratio 1.124-1.130; P<0.001). With regard to headache subtype,
O3
seems to provoke headaches, especially those related to tension and those listed as other headache
varieties. Conversely, other pollutants, especially CO and SO2
, showed the opposite association.
Conclusions: These fi ndings indicated that temperature and some air pollutants are able to affect
headaches, suggesting that weather and air pollution levels seem to have an effect on the risk of
headache.

Early postoperative anastomotic obstruction after colorectal surgery rarely develops. Herein, we present a case of a 50-year-old healthy woman who had an early postoperative anastomotic obstruction which was revealed caused by a blood clot and successfully managed by endoscopic approach. The patient was discharged after laparoscopic anterior resection and visited the emergency department one day after because of abdominal pain. Computed tomography showed that the anastomosis site was obstructed with low-density material. Intraoperative endoscopy was performed under general anesthesia and blood clot filling the lumen were identified. As the scope was advanced to the blood clot with air inflation, the blood clot was evacuated. The anastomosis site could be obstructed by blot clot with mucous debris albeit it is a rare condition. An endoscopic approach seems to be the first option in the diagnosis and treatment of postoperative obstruction at the anastomosis site and it could prevent unnecessary laparotomy.

Blood glucose homeostasis is well maintained by coordinated control of various hormones including insulin and glucagon as well as cytokines under normal conditions. However, chronic exposure to diabetic environment with high fat/high sugar diets and physical/mental stress can cause hyperglycemia, one of main characteristics of insulin resistance, metabolic syndrome, and diabetes. Hyperglycemia impairs organogenesis and induces organ abnormalities such as cardiac defect in utero. It is a risk factor for the development of metabolic diseases in adults. Resulting glucotoxicity affects peripheral tissues and vessels, causing pathological complications including diabetic neuropathy, nephropathy, vessel damage, and cardiovascular diseases. Moreover, chronic exposure to hyperglycemia can deteriorate cognitive function and other aspects of mental health. Recent reports have demonstrated that hyperglycemia is closely related to the development of cognitive impairment and dementia, suggesting that there may be a cause-effect relationship between hyperglycemia and dementia. With increasing interests in aging-related diseases and mental health, diabetes-related cognitive impairment is attracting great attention. It has been speculated that glucotoxicity can result in structural damage and functional impairment of brain cells and nerves, hemorrhage of cerebral blood vessel, and increased accumulation of amyloid beta. These are potential mechanisms underlying diabetes-related dementia. Nutrients and natural food components have been investigated as preventive and/or intervention strategy. Among candidate components, resveratrol, curcumin, and their analogues might be beneficial for the prevention of diabetes-related cognitive impairment. The purposes of this review are to discuss recent experimental evidence regarding diabetes and cognitive impairment and to suggest potential nutritional intervention strategies for the prevention and/or treatment of diabetes-related dementia.

Purpose:
A “Smart Cancer Care” platform that integrates patient-reported outcomes (PROs) with management has been established in Korea. This study focused on improving health behaviors and connecting patients to welfare services by introducing and assessing the feasibility of “Smart Cancer Care 2.0,” an enhanced version designed for monitoring complications post-cancer treatment.
Materials and Methods:
Smart Cancer Care 2.0 was developed by conducting a literature review and consulting with expert panels to identify symptoms or variables requiring monitoring and management guidelines based on the treatment type. Qualitative and quantitative surveys were conducted to assess the feasibility of the app and web system based on the experiences of patients with cancer and healthcare workers.
Results:
A total of 81 symptoms or variables (chemotherapy-, surgery-, radiotherapy-, rehabilitation-, and health management-related) were selected for management in Smart Cancer Care 2.0. PROs for these symptoms were basically categorized into three severity grades: preventive management, self-treatment, and consultation with a healthcare worker or visit to a healthcare institution. The overall mean scores in the feasibility evaluation by patients and healthcare workers were 3.83 and 3.90 points, respectively, indicating high usefulness.
Conclusion
Smart Cancer Care 2.0 leverages the existing information and communication technologies–based platform, Smart Cancer Care, and further includes health behaviors and welfare services. Smart Cancer Care 2.0 may play a crucial role in establishing a comprehensive post-discharge management system for patients with cancer as it provides suitable interventions based on patients’ responses and allows the regularly collected PROs to be easily viewed for streamlined care.

Brain infarction restricted to the unilateral hypothalamus is known to be very rare because of the abundant blood supply from the circle of Willis. We report a case of right hypothalamic infarction. A 63-year-old woman developed hyperphagia, hypersomnolence and hemihyperhidrosis limited to the left half of the face. Brain MRI revealed a high signal intensity at the right anteromedial hypothalamus.

Herba houttuyniae has been used as a constituent of herval medicine prescriptions for the treatment of inflammation, cancer, and other diseases. In the present study, we investigated the cellular effects of herba houttuyniae extract (HHE) and the signal pathways of HHE-induced apoptosis in HL-60 human promyelocytic leukemia cell line. HHE treatment caused apoptosis of cells as evidenced by discontinuous fragmentation of DNA, the loss of mitochondrial membrane potential, release of mitochondrial cytochrome c into the cytosol, activation of procaspase-9 and caspase-3, and proteolytic cleavage of poly(ADP-ribose) polymerase. Pretreatment of Ac-DEVD-CHO, caspase-3 specific inhibitor, or cyclosporin A, a mitochondrial permeability transition inhibitor, completely abolished HHE-induced DNA fragmentation. Together, these results suggest that HHE possibly causes mitochondrial damage leading to cytochrome c release into cytosol and activation of caspases resulting in PARP cleavage and execution of apoptotic cell death in HL-60 cells.

BACKGROUND AND OBJECTIVES: Hypercholesterolemia is a key factor in the development of atherosclerosis. We sought to evaluate the relation between hypercholesterolemia and plaque composition in patients with coronary artery disease. SUBJECTS AND METHODS: Study subjects consisted of 323 patients (mean 61.5 years, 226 males) who underwent coronary angiography and virtual histology-intravascular ultrasound examination. Patients were divided into two groups according to total cholesterol level: hypercholesterolemic group (> or =200 mg/dL, n=114) and normocholesterolemic group (<200 mg/dL, n=209). RESULTS: Hypercholesterolemic patients were younger (59.7+/-13.3 years vs. 62.6+/-11.5 years, p=0.036), than normocholesterolemic patients, whereas there were no significant differences in other demographics. Hypercholesterolemic patients had higher corrected necrotic core volume (1.23+/-0.85 mm3/mm vs. 1.02+/-0.80 mm3/mm, p=0.029) as well as percent necrotic core volume (20.5+/-8.5% vs. 18.0+/-9.2%, p=0.016) than normocholesterolemic patients. At the minimal lumen area site, percent necrotic core area (21.4+/-10.5% vs. 18.4+/-11.3%, p=0.019) and necrotic core area (1.63+/-1.09 mm2 vs. 1.40+/-1.20 mm2, p=0.088) were also higher than normocholesterolemic patients. Multivariate linear regression analysis showed that total cholesterol level was an independent factor of percent necrotic core volume in the culprit lesion after being adjusted with age, high density lipoprotein-cholesterol , hypertension, diabetes mellitus, smoking and acute coronary syndrome (beta 0.027, 95% confidence interval 0.02-0.053, p=0.037). CONCLUSION: Hypercholesterolemia was associated with increased necrotic core volume in coronary artery plaque. This study suggests that hypercholesterolemia plays a role in making plaque more complex, which is characterized by a large necrotic core, in coronary artery disease.
