We examined several kinds of immunocompromied patients for onyr,homycosis. The incidence of onychomycosis in the patients with connective tissue disease treated with corticosteroid was significantly higher than the incidences in the patients with solid tumors trcated with chemotherapeutic agents, in the patients with leukernia (WBC<1, 000/cm3), and in the control patients. Although conventional corticosteroid trcatment do not disseminate the superficial fungal infection, it may perpetuate the low grade dermatophytosis.

Purpose: Prior research has indicated that stroke can influence the symptoms and presentation of neurogenic bladder, with various patterns emerging, including abnormal facial and linguistic characteristics. Language patterns, in particular, can be easily recognized. In this paper, we propose a platform that accurately analyzes the voices of stroke patients with neurogenic bladder, enabling early detection and prevention of the condition. Methods: In this study, we developed an artificial intelligence-based speech analysis diagnostic system to assess the risk of stroke associated with neurogenic bladder disease in elderly individuals. The proposed method involves recording the voice of a stroke patient while they speak a specific sentence, analyzing it to extract unique feature data, and then offering a voice alarm service through a mobile application. The system processes and classifies abnormalities, and issues alarm events based on analyzed voice data. Results: In order to assess the performance of the software, we first obtained the validation accuracy and training accuracy from the training data. Subsequently, we applied the analysis model by inputting both abnormal and normal data and tested the outcomes. The analysis model was evaluated by processing 30 abnormal data points and 30 normal data points in real time. The results demonstrated a high test accuracy of 98.7% for normal data and 99.6% for abnormal data. Conclusions Patients with neurogenic bladder due to stroke experience long-term consequences, such as physical and cognitive impairments, even when they receive prompt medical attention and treatment. As chronic diseases become increasingly prevalent in our aging society, it is essential to investigate digital treatments for conditions like stroke that lead to significant sequelae. This artificial intelligence-based healthcare convergence medical device aims to provide patients with timely and safe medical care through mobile services, ultimately reducing national social costs.

OBJECTIVE: To determine if the physical design and organizational structure of rehabilitation stroke unit (RSU) is related to the amount of patients' activity pattern. METHOD: An observational study was conducted using behavioral mapping method. Time samples of the motor activity of patients following stroke were taken at 10-minute interval, between 7 AM and 7 PM both on weekdays and weekends. At each observation, physical activity patterns, location in which the patients spent their time, and other person present were recorded. RESULTS: RSU patient spent less time in non-therapeutic activity and more time in therapeutic activity (p<0.05). There were significant differences in the locations of patient's position between the two types of ward (p<0.05). RSU patients had significantly more interaction with formal carerand less time disengaged (p<0.05). The proportion of time in therapeutic activity was low in all location, with patients spending many hours in bed and doing nothing. There was no significant differences in total Functional Independence Measure (FIM) scores at admission and on discharge, FIM gain, and FIM efficiency between RSU and mixed rehabilitation ward (p<0.05). CONCLUSION: In spite of quantitative difference, the two wards had similar patterns of treatment activity and deployment of staff. These maybe resulted in similar treatment experiences for patient and no functional differences between two wards. It appears that strategies are required so that patients can be practicing at an more appropriate level.

Cavernous malformation is an important cause of cerebral hemorrhage in pregnant women. We experienced a case of cesarean section followed by neurosurgery for resection of ruptured cavernous malformation of pons in a 24-year-old pregnant woman. Establishing integrated treatment strategy for pregnant women with cavernous malformation is difficult because of the small number of cases. Therefore, the cooperation between the brain surgeon, anesthesiologist and obstetrician is essential when surgical intervention is needed. Despite aspiration pneumonia, the patient successfully underwent surgery. We reported this case along with a brief literature review.

This experiment was performed to evaluate the morphological responses of 5-fluorouracil or mitomycin C on the spleen of the mice. 5-fluorouracil (60 mg/kg) or mitomycin C (400 microgram/kg) were injected subcutaneously every other day, and the animals were sacrificed at 1 week and 2 weeks following the first injection. Pieces of the tissue were taken from the spleen, fixed in 10% neutral formalin for light microscopy. The paraffin sections stained with hematoxylin-eosin, Masson-trichrome, Bielschowsky's silver impregnation or aldehydefuchsin. For electron microscopy, the tissues were prefixed with 2.5% glutaraldehyde-1.5% paraformaldehyde followed by post-fixed with 1% osmium tetroxide. The ultrathin sections stained with uranyl acetate and lead citrate. The observed results were as follows: 1. On histological study, in the mitomycin C treated group, macrophages which contain pyknotic nuclei were observed more frequently than in those of 5-fluorouracil treated group. 2. In the 5-fluorouracil treated group, positive reactions to Masson-trichrome and Bielschowsky's silver impregnation were observed in the splenic capsule and traculae at the 1 week, and weak postive stains were observed at the 2 weeks. 3. In the mitomycin C and the 5-fluorouracil group, positive staining reaction to aldehyde-fuchsin were observed in splenic capsule, trabeculae and around artery at the 1 week and 2 weeks. 4. On the ultrastructural study, distended cisternae of granular endoplasmic reticula were observed frequently at 1 week. 5. In the mitomycin C treated group, myelin figures in the lymphocytes and reticular cells were observed more frequently than in those of 5-fluorouracil treated group. From the above results, it was concluded that lymphocytes and reticular cells of the spleen were slightly damaged by 5-fluorouracil or mitomycin C, and mitomycin C seems more harmful on the spleen than 5-fluorouracil does.

PURPOSE: This study was to determine the incidence and severity of venous irriation in patients receiving vinorelbine tartrate (Navelbine ) in combination chemotherapy. MATERIAL AND METHODS: Twenty four patients histologically confirmed non-small cell lung cancer were enrolled in this study who receiving vinorelbine in combination chemotherapy through a peripheral vein from Oct. 1997 to Mar. 1999 with retrospective study design method. One group was 6~10 minutes infusion rate, the other was 10~20 minutes infusion rate with the same free-flow intravenous infusion. RESULTS: A total of 126 infusions were observed in this study. Sixty-two infusions were admi nistered at the 6~10 minutes, and 64 infusions were administered at the 10~20 minutes. The incidence of any venous irritation was 3.2% (2/62) in the group that received the infusion in 6~10 minutes and 10.9% (7/64) in 10~20 minutes (p=0.164), so we could not acquire any statistical significance. However the incidence of severe venous irritation (grade 3, 4) was 0% (0/62) in 6~10 minutes infusion group and 9.4% (6/64) in 10~20 minutes infusion group. There was a significant difference between two groups (p=0.028) CONCLUSION: Our results suggest that venous irritation associated with vinorelbine tartrate infusion can be reduced by shorter duration of administration and vinorelbine tartrate might be recom mended to administer at 6~10 minutes infusion in clinical practice.

Controlled mechanical ventilation (CMV) with positive and expiratory pressure (PEEP) is often used to improve the pulmonary gas exchange in patients with acute respiratory distress syndrome. However, this ventilatory technique may induce hemodynamic and hormonal changes which may lead to vital organ dysfunction, such as oliguria. Low dose dopamine, acting as a dopaminergic receptor agonist, may improve vital organ perfusions, i.e. renal, mesenteric and coronary perfusions. The purpose of this current study was to evaluate the effects of low dose dopamine on renal function and hemodynamic change during controlled mechanical ventilation with PEEP. The study was performed on 10 patients treated with PEEP in the surgical intensive care unit. Starting with 0 cmH2O of PEEP and adding 4 cmH2O of PEEP at 4-hour intervals until it reached 12 cmH2O of PEEP, dopamine, 2 ug/kg/min, was selectively, administered, intravenously during the last two hours of each four hour intervals. Following each procedure, hemodynamic parameters, urine output, creatinine clearance and fractional excretion of sodium were measured. The cardiac index and mean arterial pressure had both decreased, but the mean pulmonary arterial pressure was increased at 12 cmH2O of PEEP compared with 0 cmH2O of PEEP in both groups with and without low dose dopamine. The main result of this study was that low dose dopamine attenuated the decrease of the cardiac index, urine output and creatinine clearance induced by mechanical ventilation with PEEP at 12 cmH2O.

PURPOSE: To test the radiosensitizing effect of the newly synthesized novel histone deacetylase inhibitor, SK-7041 in vivo. MATERIALS AND METHODS: The RIF-1 cell line was implanted into the back of a 6-week-old female C3H mouse, intradermally. The mice were grouped into control, drug, radiation (RT), and RT+drug group. SK-7041, 4 mg/kg was administered intraperitoneally for six cycles every 12 hours for mice in the drug and RT+drug group. An identical volume of phosphate buffered saline (PBS) was administered at the same frequency to mice in the control and RT groups. A single 5 Gy fraction was delivered to mice in RT and RT+drug group 6 hours after the fourth delivery. The volume of the implanted tumor was measured every 2~3 days to formulate the growth delay curve. RESULTS: For the control, drug, RT, and RT+drug groups, the average duration for implanted tumor to reach a volume of 1,500 mm3 was 10 days, 10 days, 9 days, and 12 days, respectively. Moreover, the tumor volume on D14 was 276.7 mm3, 279.9 mm3, 292.5 mm3, and 185.5 mm3, respectively (p=0.0004). The difference for the change in slope for the control and drug versus the RT and RT+drug groups were borderline significant (p=0.0650). CONCLUSION: The results of this study indicate that SK-7041 has a radiosensitizing effect for the RIF-I cell line in vivo at a low concentration and this effect may be synergistic. Implementing this result to clinical trial is warranted.
