Given that household food security issues have become the concern of the Korean society, this study aimed to develop food security measures for the Korean population. Based on the literature reviews on previously developed food security measures, the 18-item US household food security survey module (US HFSSM) was adapted. The developed food security measures was assessed by qualitative validity method. It was evaluated and modified by face validity by expert focus groups belong to university, public health center, and government agencies and by cognitive interview by 40 subjects with low household income who live in an urban community and are participants in welfare programs of local districts. Then, it was reviewed and revised by the National Institute of the Korean Language and the advisory committee for nutrition survey of Korean National Health and Nutrition Examination Survey (KNHANES). The results showed that the developed questionnaire items were well adapted by expert focus groups and general subjects, showing the feasibility of measuring food security with the developed measures although there were discrepancies in some expressions of questionnaire items between experts focus groups and general subjects. The study to assess reliability and quantitative validity of the developed food security measures should be further needed to examine its application for KNHANES.

Modified electroconvulsive therapy (ECT) which started in 1950s is a safe and efficacious treatment for several mental disorders including mood disorders and psychotic disorders. However, its usage in present days is still limited by misconceptions and stigmata of ECT. This paper overviews the background from which the stigmata of ECT stemmed and the current status of stigmata surrounding ECT among the public and medical professionals. In addition, a few potential strategies for reducing stigmata of ECT are provided in this review.

Malignant hyperthermia is a rare, fatal pharmacogenetic disorder that occurs during general anesthesia following exposure to a depolarizing muscle relaxant, such as succinylcholine, or volatile anesthetics. Clinical findings in malignant hyperthermia include muscle rigidity, sinus tachycardia, increased CO2 production, skin cyanosis with mottling, and marked hyperthermia. For treatment, cooling techniques must be accompanied by discontinuation of the provocative medication. Furthermore, dantrolene administration is the mainstay of treatment for malignant hyperthermia, and should be initiated as soon as the diagnosis is suspected. We recently experienced a case with post-operative fever of 41.0degrees C refractory to conventional anti-pyretic measures and finally resolved with dantrolene administration, in a patient with methicillin-sensitive Staphylococcus aureus monoarthritis of the knee and rapid progression of diffuse septic pneumonia requiring mechanical ventilation.

OBJECTIVE: To compare the usefulness of magnetic resonance cholangiopancreatography (MRCP) and MR angiography (MRA) in differentiating malignant from benign intraductal papillary mucinous tumors of the pancreas (IPMTs), and to determine the findings which suggest malignancy. MATERIALS AND METHODS: During a 6-year period, 46 patients with IPMT underwent MRCP. Morphologically, tumor type was classified as main duct, branch duct, or combined. The diameter of the main pancreatic duct (MPD), the extent of the dilated MPD, and the location and size of the cystic lesion, septum, and communicating channel were assessed. For all types of IPMTs, enhanced mural nodules and portal vein narrowing were evaluated at MRA. RESULTS: Combined-type IPMTs were more frequently malignant (78%) than benign (42%) (p < 0.05). Compared with benign lesions, malignant lesions were larger, and the caliber of the communicating channel was also larger (p < 0.05). Their dilated MPD was more extensive and of greater diameter (p < 0.05), and the presence of mural nodules was more frequent (p < 0.001). CONCLUSION: Combined MRCP and MRA might be useful for the differential diagnosis of malignant and benign IPMTs of the pancreas.

OBJECTIVE: We evaluated cell viability and proliferation activity of peripheral lymphocytes as potential models of neuronal death in Alzheimer's disease (AD). METHODS: We analyzed the cell viability and proliferation activity of phytohemagglutinin (PHA)-activated lymphocytes from 68 AD patients and 33 normal controls. The cellular measures were made at baseline (0 hr), 24 hrs, 48 hrs, 72 hrs, and 96 hrs after PHA stimulation. RESULTS: Cell viability in the AD patients was significantly decreased at 72 hrs and 96 hrs, compared with the normal controls. The declining ramp of the proliferation activity from 48 hrs to 72 hrs after PHA stimulation was significantly related to cell viability at 72 hrs and at 96 hrs in the AD patients. CONCLUSION: Lymphocytes from patients with AD have altered viability and proliferation characteristics in culture following PHA stimulation. These findings suggest that lymphocytes may be used as a peripheral tissue model of cell cycle dysregulation in AD.

Torsades de pointes associated with a prolonged QT interval is a life-threatening arrhythmia, which may be induced by any of the following: drugs, electrolyte imbalances, severe bradycardia and intracranial hemorrhage. Torsades de pointes is characterized by beat-to-beat variations in the QRS complexes in any ECG leads with rates of 200~250 per minute. Fluoroquinolones are widely used and well tolerated antibacterial agents. However, prolongation of the QT interval leads rarely to Torsades de pointes as a significant adverse effect. So, it should be used with caution in high-risk patients for developing Torsades de pointes. We report one case of 67-year old man with contact burns who experienced Torsades de pointes, which probably resulted from the use of levofloxacin, and no further episode occurred after its withdrawal.

Biloma is a rare disorder, and is defined as an abnormal extrahepatic or intrahepatic collection of bile within a defined capsular space. The common causes of biloma are iatrogenic and trauma. Spontaneous biloma, especially caused by pancreatic cancer, is very rare. An 86-year-old man was admitted with abdominal pain and fever. The patient denied a history of abdominal surgery, endoscopic retrograde cholangiography, or trauma. Abdominal computed tomography demonstrated a huge collection of fluid in the left lobe of the liver, dilatation of the intra and proximal common bile duct, and a heterogeneous enhancing mass in the pancreatic head portion. Percutaneous drainage under ultrasound guidance was performed, and the fluid analysis was compatible with biloma. A plastic stent was endoscopically inserted into the common bile duct to treat continuous drainage of the fluid despite percutaneous drainage. We report a case of biloma developed spontaneously in a patient with pancreatic cancer and successfully treated by endoscopic biliary stenting.

The Korean Cancer Pain Assessment Tool (KCPAT), which was developed in 2003, consists of questions concerning the location of pain, the nature of pain, the present pain intensity, the symptoms associated with the pain, and psychosocial/spiritual pain assessments. This study was carried out to evaluate the reliability and validity of the KCPAT. A stratified, proportional-quota, clustered, systematic sampling procedure was used. The study population (903 cancer patients) was 1% of the target population (90,252 cancer patients). A total of 314 (34.8%) questionnaires were collected. The results showed that the average pain score (5 point on Likert scale) according to the cancer type and the at-present average pain score (VAS, 0-10) were correlated (r=0.56, p<0.0001), and showed moderate agreement (kappa=0.364). The mean satisfaction score was 3.8 (1-5). The average time to complete the questionnaire was 8.9 min. In conclusion, the KCPAT is a reliable and valid instrument for assessing cancer pain in Koreans.

Pneumatosis cystoides intestinalis (PCI), characterized by presence of intramural gas cyst in the intestinal wall is associated with various medical condition. Polymyosistis, however, is rarely associated with PCI. Few cases are reported in the world, and none has not been reported previously in Korea. A 67-year-old woman with polymyositis developed mild abdominal pain and abdominal distension during treatment with steroid and azathioprine. Radiographic findings including CT scan showed intraperitoneal free gas and intramural air, compatible with PCI. The patient's symptom and clinical findings improved after the treatment with antibiotics and high-dose oxygen therapy.
