Human diphyllobolthriasis is chiefly caused by infection with Diphyllobothrium latum(D. latum) through eating raw or unproperly cooked fish such as salmon, trout or perch. D. latum is worldwidely distributed, but not a common parasite of humans, and its prevalence in Korea is not high. The first worm-proven case of D. latum infection was first reported in 1971 and about 30 cases have been reported in Korea until now. However, with the increasing popularity of eating raw salmon, trout and perch, this tapeworm infection tends to increase in Korea. Most of the patients infected by D. latum have not showed the specific symptoms and only non-specific gastrointestinal symptoms(anorexia, nausea, vomiting, diarrhea, abdominal pain). We report a case which includes a chain whitish, threadlike tapeworm segments spontaneously discharged in the patients stool. On reviewing the literature, the present case is the first report of D. latum infection by eating cultured salmon. The patient was treated with 600mg single dose of Praziquantel.

Myokymia is a clinical phenomenon characterized by undulating, vermicular, rippling and wavelike movements spreading across the muscle surface. Facial myokymia is an unusual complication of brainstem hemorrhage. It tends to occur in brainstem tumor or multiple sclerosis. We report a 51-year-old man with continuous facial and neck myokymia after brainstem hemorrhage, who revealed focal myokymic discharges in face, neck and pharyngolaryngeal muscles in-nervated by cranial nerve V, VII, X, and XI. After injection of 20-80 units of Botulinum toxin type A (Dysport ) to the left orbicularis oris, mentalis, mylohyoid and posterior belly of digastric muscles, amplitude of continuous myokymic discharges was markedly reduced. We recommend Botulinum toxin injection as a very effective therapeutic method in managing focal movement disorders.

PURPOSE: A consecutive series of 710 patients who underwent curative gastrectomy for carcinoma was studied with a special reference to the number or frequency of lymph node metastasis and the patient's prognosis. MATERIAL AND METHODS: Survival rates were calculated by the Kaplan-Meier method, and the difference between each group was evaluated statistically by the log-rank method. Follow-up was obtained for 709 patients (99.9%). RESULTS: According to the number of lymph nodal metastases, the five year survival rate for group 1 (1~3 positive nodes) was 50.9%; for group 2 (4~6 positive nodes), 56.7%; and for group 3 (more than 6 positive nodes), 12.0% (p<0.0001). According to the frequency of lymph node metastases, the five year survival rate for those with up to 25 per cent frequency of metastases was 47.5%; for those with up to 50 per cent frequency of metastases, 15.6%; and for those with greater than 50 per cent metastases, 6.3% (p<0.0001). According to the frequency of the regional lymph nodes (which include perigastric nodes along the lesser and greater curvatures, nodes located along the left gastric, common hepatic, splenic, and celiac arteries) metastasis, we categorized them as group 0 (N0: no metastasis), 1 (N1: metastasis in up to 25%), and 2 (N2: metastasis in greater than 25%). CONCLUSION: This subdivision could be successfully applied to the clinical evaluation of gastric carcinoma (five year survival rate for N0, 86.9%; for N1, 49.0%; and for N2, 10.7% (p<0.0001)) without difficulty in dividing certain lymph nodes into the correct location.

OBJECTIVE: To evaluate working condition in way of measuring working posture and muscle tension using the desktop personal computer and notebook personal computer having different screen height. METHOD: Seventeen healthy men performed wordprocessing task in three workstation: desktop PC on the conventional computer table (DPC (on)); desktop PC under the 'inside' type computer table (DPC (under)); notebook PC on the table (NPC). The viewing distance and angle, head and neck angle, thoracic bending and trunk inclination were measured. Muscle tension of right posterior neck muscle, upper trapezius, sternocleidomastoid (SCM), and upper back muscle was also measured by integrated electromyogram (IEMG). RESULTS: 1) The viewing distance was the longest in DPC (under). 2) The lower the screen height, the more downward viewing angle and more flexed position in upper neck. 3) The posterior neck muscle tension was the lowest in DPC (on). 4) Stooped position was most frequently seen in NPC and the highest tension of posterior neck muscle and upper back muscle was shown in NPC. 5) In relation between postural analysis and muscle tension, muscle tension decreased with increasing backward reclining position, and the neck and thorax became more erect with increasing in viewing distance. CONCLUSION: These results suggest that the stooped posture was worst and most frequently seen in NPC. If neck flexion is avoided, DPC (under) position could lessen the visual and musculoskeletal problem. More Ergonomical study would be needed about working posture using computer.

Purpose:
To report the clinical efficacy of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser iris cystotomy in iris cysts.
Methods:
We examined three eyes with primary iris cysts diagnosed by ultrasound biomicroscopy that had fewer cornea endothelial cells or reduced visual acuity due to an occluded visual axis. Nd:YAG laser cystotomy was done. The logarithm of the minimum angle of resolution (logMAR) visual acuity, intraocular pressure (IOP), and specular microscopy test at baseline and last follow-up were reviewed.
Results:
The average patient age was 54.0 ± 5.3 years; the mean follow-up was 11.7 ± 2.1 months. The baseline and final logMAR visual acuity were 0.23 ± 0.25 and 0.16 ± 0.15, respectively. Visual acuity improved, although not significantly (p = 0.317). The baseline and final IOP were 14.7 ± 2.3 and 13.7 ± 0.6 mmHg, respectively (p = 0.276). The corneal endothelial cell density (p = 0.109), hexagonality (p > 0.999), and coefficient of variation (p = 0.285) were not significantly different after treatment. There were no serious complications or recurrence.
Conclusions
After Nd:YAG laser cystotomy, the cell density and morphology of corneal endothelial cells changed little. It can be considered an effective treatment when there is a decrease in corneal endothelial cells or occlusion of the visual axis.

DNA microarray is a high-throughput biomedical technology that monitors gene expression for thousands of genes in parallel. The abundance and complexity of the gene expression data have given rise to a requirement for their systematic management and analysis to support many laboratories performing microarray research. On these demands, we developed Xperanto for integrated data management and analysis using user-friendly web-based interface. Xperanto provides an integrated environment for management and analysis by linking the computational tools and rich sources of biological annotation. With the growing needs of data sharing, it is designed to be compliant to MGED (Microarray Gene Expression Data) standards for microarray data annotation and exchange. Xperanto enables a fast and efficient management of vast amounts of data, and serves as a communication channel among multiple researchers within an emerging interdisciplinary field.

OBJECTIVE: To delineate the role of antidiuretic hormone (ADH) in relation to nocturnal polyuria, and to identify the factors influencing on the diurnal antidiuretic hormone level. METHOD: The ADH was measured by radioimmuoassay at daytime (2:00 PM) and at nighttime (2:00 AM) with nocturnal polyuria group (11) and without nocturnal polyuria group (8). Urine volume, serum osmolarity, urine osmolarity, and blood pressure were also measured at the same time. RESULTS: 1) The ADH at 2:00 AM did not increase in nocturnal polyuria group, although it increased in no-symptom group. 2) There was a statistically significant correlation between wheelchair ambulation time and daytime ADH level. 3) The difference of ADH level between daytime and nighttime showed decrease in orthostatic hypotension group. CONCLUSION: There was relationship between nocturnal polyuria and diurnal variation of ADH level. The ADH concentration seems to be influenced by the postural factors and sympathetic factors.

Emphysematous pyelitis is uniquely characterized by gas-forming infection restricted to the renal collecting system. This disease entity is uncommon, and shows preferred occurrence in patients with diabetes mellitus or urinary tract obstruction. We report a case of bilateral emphysematous pyelitis in a diabetic end-stage renal disease patient undergoing peritoneal dialysis therapy. The patient was treated by medical treatment only and then recovered from infection, and she has maintained peritoneal dialysis until today. The authors report this case as a successful medical treatment for emphysematous pyelitis accompanying multiple risk factors, such as diabetes mellitus, amorphous medullary kidney stones, and even underlying maintaining peritoneal dialysis.

PURPOSE: Few studies have evaluated changes in quality of life (QoL) in relation to changes in body mass index (BMI) after gastrectomy. This study aimed to evaluate the impact of postoperative changes in BMI on QoL after distal gastrectomy in gastric cancer patients. METHODS: QoL data from the European Organization for the Research and Treatment of Cancer (EORTC) gathered via the QLQ-C30 and QLQ-STO22 questionnaires were obtained from 1,036 patients preoperatively and at 1 year postoperatively. The patients were divided into 2 groups: group 1 - decreased postoperative BMI and group 2 - unchanged or increased postoperative BMI. RESULTS: There were 577 patients in group 1 and 459 in group 2. According to global health status and functional scales, emotional functioning (P = 0.035) was significantly worse in group 1 than in group 2 at 1 year postoperatively. Furthermore, there were significant decreases in QoL symptom scale scores, including fatigue (P = 0.016), nausea and vomiting (P = 0.002), and appetite loss (P = 0.001) scores, in group 1 compared with group 2. Regarding QLQ-STO22, reflux symptoms (P = 0.020), anxiety (P = 0.003), and body image (P = 0.003) were significantly worse in group 1 than in group 2 at 1 year after surgery. CONCLUSION: BMI changes after distal gastrectomy influence QoL. Focus on controlling gastrointestinal symptoms and providing psychological support is essential in patients with decreased BMI after surgery. Patients should be offered follow-up care to assist them in maintaining BMI, for example, through dietary-behavior modifications and via intensive nutritional support, to prevent QoL deterioration after distal gastrectomy.

PURPOSE: Patients and their caretakers need to understand various problems and requirements in the dying process so that they may prepare for death for the rest of their remaining life. Accordingly, a systematic audio-visual resource was developed to educate hospice patients and their families at the palliative care ward about the process of dying. METHODS: For the development of an audio-visual resource, a initial education material was produced in the form of simple and accessible Power Point handouts based on literature study. Then, the program was completed through five rounds of a process, including expert advice, revision, update and evaluation. RESULTS: The final version of the program was filmed with cooperation of the medical literature information division. Using the program, patients and families were educated through five phases over three sessions for a total 26 minutes and 34 seconds. CONCLUSION: The significance of this study lies in the fact that it was conducted after the establishment of the palliative care ward, which made it easier for nurses provide the education. It is expected that the program may be used by hospice specialists as well as nurses as an education resource for hospice patients and their families.
