Thombolytic therapy and placement of vascular metallic stent can be used for the treatment of lilac venous stenosis and thrombosis, but these treatments increase the risk of pulmonary thromboembolism. Inferior vena cava filter was developed for the prevention of recurrent pulmonary thromboembolism due to lower extremity deep vein thrmobosis and has been regarded as relatively safe and effective treatment modality. We experienced good result of combined treatment of inferior vena filter, thrombolytic therapy and placement of right lilac venous metallic stent in a patient with severe stenosis and thrombosis at both common lilac veins.

BACKGROUND: Disinfection is essential for the prevention of hospital infoction. Tego-51, one of the amphoteric surfactants based on the dodecyl-di( aminoethyl)-glycine, has been considered as an effctive disinfectant having a broad specturn of antimicrobial activity. We evaluated the disinfective activity of Tego-51 against several clinical isolates of bacteria and yeasts including Helicobacter pyiori. METHODS: Twenty three strains of vacteria including H. pylori, and a strain of yeast were exposed to the various concentrations (0.05%, 0.01%, 0.005%) of Tego-51 for the various periods (0.5, 1, 2, 4, 8, 16min). After the exposure to Tego-51 disinfectant, 0.01 mL of mixture of microorfanisms and Tego-51 was inoculated into brain-heart infusion broth, into Sabouraud dextrose agar. or Wilkins-Chalgren agar with 10% sheep blood, and incubated at 37 degrees C for 48 hours or in the Campy Pouch microaerophilic system. RESULTS: Most strains were killed within 30 seconds after an exposure to 0.01% of Tego-51, but Proteus mirabilis was eradicated after two minutes of exposure. At the concentration of 0.005 % concentration. P. mirabilis and Bacillus subtilis were killed after eight minutes od exposure. H. pylori was killed with 0.005% Tego-51within 30 seconds. Conslusions: This study showed that Tego-51disinfectant was effective for the disinfection of commonly isolated bacteria and yeast from hospital. It may be recommended that Tego-51 should be used at concentration greater than 0.1% for the effective disinfection of skin, instruments and hospital floors.

PURPOSE: This study was conducted to investigate the epidemic pyrogenic reactions that occurred hospital-widely in 51 patients on 30-31 Mar. 1995 at a tertiary, educational, and acute care hospital. METHODS: The remained intravenous (IV) drugs and IV fluids that were infused to patients (N=51) who developed pyrogenic reactions were cultured and tested pyrogenic matter. Pyrogenic test was done by Limulus Amebocyte Lysate (PyrotellRMA,USA). RESULTS: IV normal saline 50 cc bottles (AAXSAT and AAX5AV) those were collected being used from case patients, and new bottles stocked in the drug storage were positive to pyrogenic test. Used normal saline collected from case patients were cultured coagulase-negative Staphylococus. Moreover the company, manufacturer of these fluids reported the positive pyrogenic test on these IV fluids (AAXSAT and AAX5AV). CONCLUSION: This epidemic was a pyrogenic reaction for infused the intrinsic contaminated fluid with pyrogen. We could prevent not the additional pyrogenic reactions in study hospital but national wide epidemics to apply the rapid and well-designed epidemic investigation and infection control.

MR finding of melanoma shows peculiar signal intensity based on paramagnetic effect of melanin or intratumoral hemorrhage, which displays decreased T1 and T2 relaxation times in many cases. Authors report MR findings in two cases of intracranial metastatic melanoma, which is pathologically confirmed by operation.

BACKGROUND: An Epidemiological study was undertaken to evaluate the prevalence of E. vermicularis infestation among children in kindergartens. METHODS: A total of 247 cellotape anal swab specimens from kindergarten children in Inchon were examined for E. vermicularis eggs. Each specimen was collected in the morning. RESULTS: Out of 247 specimens from two kindergartens in Inchon, E. vermicularis eggs were detected in 168 specimens, the egg detection rate being 68.0%. The egg detection rates in boys and girls were 63.9% out of 133 children and 72.8% out of 114 children, respectively. The egg detection rate in girls was higher than that of boys. The egg detection rates by age group was 65.5%(age 3), S7.4%(age 4), 72.0%(age 5) and 75.4%(age 6), respectively. CONCLUSIONS: Enterobiasis is a cosmopolitan infection. Surveys for children of kindergartens indicate that E.vermicularis is probably the most widely distributed human helminth, its incidence varing from 59.2% to 73.8% in groups studied since pinworm infection is frequently a familial problem that infestation of the household frequently results in reinfection. Careful washing of hands and cleansing of fingernails before meals and after use of the toilet are the most practical measures, all member of family should be treated simultaneously when practicable.

Unlike the case of adult obstructive sleep apnea syndrome (OSAS), there was no consistent finding on the changes of sleep architecture in childhood OSAS. Further understanding of the sleep electroencephalogram (EEG) should be needed. Non-linear analysis of EEG is particularly useful in giving us a new perspective and in understanding the brain system. The objective of the current study is to compare the sleep architecture and the scaling exponent (alpha) from detrended fluctuation analysis (DFA) on sleep EEG between OSAS and normal children. Fifteen normal children (8 boys/7 girls, 6.0+/-2.2 years old) and twelve OSAS children (10 boys/2 girls, 6.4+/-3.4 years old) were studied with polysomnography (PSG). Sleep-related variables and OSAS severity indices were obtained. Scaling exponent of DFA were calculated from the EEG channels (C3/A2, C4/A1, O1/A2, and O2/A1), and compared between normal and OSAS children. No difference in sleep architecture was found between OSAS and normal controls except stage 1 sleep (%) and REM sleep latency (min). Stage 1 sleep (%) was significantly higher and REM latency was longer in OSAS group (9.3+/-4.3%, 181.5+/-59.9 min) than in controls (5.6+/-2.8%, 133.5+/-42.0 min). Scaling exponent (alpha) showed that sleep EEG of OSAS children also followed the 'longrange temporal correlation' characteristics. Value of alpha increased as sleep stages increased from stage 1 to stage 4. Value of alpha from C3/A2, C4/A1, O1/A2, O2/A1 were significantly lower in OSAS than in control (1.36+/-0.05 vs. 1.41+/-0.04, 1.37+/-0.04 vs. 1.41+/-0.04, 1.37+/-0.05 vs. 1.41+/-0.05, and 1.36+/-0.07 vs. 1.41+/-0.05, p<0.05). Higher stage 1 sleep (%) in OSAS children was consistent finding with OSAS adults. Lower 'alpha' in OSAS children suggests decrease of self-organized criticality or the decreased piling-up energy of brain system during sleep in OSAS children.

International Neurourology Journal 2023;27(4):280-286
Purpose:
In this paper, we present the development of a monitoring system designed to aid in the management and prevention of conditions related to urination. The system features an artificial intelligence (AI)-based recognition technology that automatically records a user’s urination activity. Additionally, we developed a technology that analyzes movements to prevent neurogenic bladder.
Methods:
Our approach included the creation of AI-based recognition technology that automatically logs users’ urination activities, as well as the development of technology that analyzes movements to prevent neurogenic bladder. Initially, we employed a recurrent neural network model for the urination activity recognition technology. For predicting the risk of neurogenic bladder, we utilized convolutional neural network (CNN)-based AI technology.
Results:
The performance of the proposed system was evaluated using a study population of 30 patients with urinary tract dysfunction, who collected data over a 60-day period. The results demonstrated an average accuracy of 94.2% in recognizing urinary tract activity, thereby confirming the effectiveness of the recognition technology. Furthermore, the motion analysis technology for preventing neurogenic bladder, which also employed CNN-based AI, showed promising results with an average accuracy of 83%.
Conclusions
In this study, we developed a urination disease monitoring system aimed at predicting and managing risks for patients with urination issues. The system is designed to support the entire care cycle of a patient by leveraging AI technology that processes various image and signal data. We anticipate that this system will evolve into digital treatment products, ultimately providing therapeutic benefits to patients.
