Objective : An apparent increase of use of drugs affecting hemostasis in our neurosurgical department since the 1990s has encouraged us to investigate whether these drugs influence the clinical course and results of surgery for chronic subdural hematoma (CSDH). Methods : This retrospective analysis included 178 patients admitted for CSDH from 2007 to 2011 who were divided into two groups : on drugs affecting hemostasis (40; 22%) and no bleeding disorders (138; 78%). Medications in the first group included oral anticoagulants (33; 82.5%), antiplatelets (5; 12.5%) and low molecular weight heparins (2; 5%). Results : The patients on drugs affecting hemostasis were older ($74.3{\pm}7.4$ vs. $68.4{\pm}14.8$; p-value 0.01) and the group without bleeding disorders had more head trauma history (61% vs. 38%, p-value 0.01). The groups did not differ in bilateral hematoma rates (25% vs. 20%, p-value=NS). At diagnosis, mean hematoma thickness was lower in patients on drugs affecting hemostasis ($18.7{\pm}7.4mm$ vs. $21.9{\pm}7.9mm$, p-value<0.01). Average stay of hospital was 1 day longer in patients on drugs affecting hemostasis ($11.7{\pm}4.1$ vs.$10.9{\pm}5.3$, p-value=NS) and was related to the necessity of bleeding disorder reversal. Mean neurological status at presentation was similar between the groups (p-value=NS) as was the likelihood of hematoma recurrence (p-value=NS). Glasgow Outcome Scale results were comparable. Conclusion : Patients on drugs affecting hemostasis are less often aware of a head trauma history, possibly suggesting a higher CSDH risk after minor trauma in this group. In these patients, smaller hematomas are symptomatic, probably due to faster hematoma formation. Drugs affecting hemostasis do not affect treatment results.

Background: To examine whether offspring improve or reduce quality of life (QOL) among cancer patients and survivors. Materials and Methods: We used data from the Korean Longitudinal Study of Aging (KLoSA) from 2008 to 2011. There were 490 research subjects in our study: 245 cancer patients and survivors and 245 controls matched using propensity scores. Results: For cancer patients and survivors with no offspring, the QOL estimate was -2.831 lower (SE: 5.508, p-value: 0.623) than that of those with two offspring, while for those with five or more offspring, the QOL estimate was 7.336 higher (SE: 2.840, p-value: 0.036). For non-cancer patients and survivors with one child, the QOL estimate was -11.258 lower (SE: 2.430, p-value: 0.002) than that of those with two offspring, while for those with five or more offspring, the QOL estimate was -4.881 lower (SE: 2.484, p-value: 0.090). Conclusions: This article provides evidence for a beneficial effect of offspring upon QOL in cancer patients and survivors, indicating that offspring are important for them.

To study the nutritional value of general hospital diet, the author surveyed in 5 hospitals which are located in Pusan. Thd information on appetite and dietary habits was taken from the questionnaire results of 166 patients and 185 non patients. The survey of nutritional value was conducted on 104 males and 61 females hospitalized patients, taking three consecutive days in each hospital. RESULTS : 1. The average nutritive value of general diet per patient per patient per day served in hospitals was 2446.601$\pm$57.31 kcal, 100.23$\pm$8.18g protein, 42.35$\pm$6.46g fat, 413.35$\pm$31.46g carbohydrate. 2. The average percentage of diet consumed by patients per day was 69.7$\pm$4.5%. 3. The average nutrient intake by patients per day was 2025.94$\pm$194.46kcal, 77.04$\pm$6.38g protein, 31.71$\pm$6.80g fat, 356.20$\pm$26.40g carbohydrate. 4. The meals were taken more regularly by patient group than by non patient group. 5. The psychological appetite was lower in patient group. 6. The patients thought hospital diet as reliable and were willing to take diets well in order to get well as soon as possible.

Purpose: As UBC IRMA is being tested, patients out of the reference value are reacting within the value again a few days later the urine collection tested, which causes the reliability of the test to decrease as a result. In this study, we can assume that the physiological changes in the factors would affect the results. The purpose of the study is to find out whether hematuria and proteinuria in the sample as well as the interval time (3 hours or more recommended) have affected the results. As a result, we could discover the changes in factors and increase the reliability of the test. Materials and Methods: 468 people (female: 249, male: 219) who came for the check-up were presented herein for medical examination from 2013.3.15 to 2013.1.2. Some people out of 468 who have reacted onto the reference value were divided into group low titer zone, ow-middle titer zone, and middle-high titer zone and tested for hematuria and proteinuria. During that period, 48 outpatients were asked to fill in a questionnaire regarding the urination interval time. The reagents used were (IDL Biotech AB, Sweden) and UBC IRMA. Results: Of the patients that are formed in the reference value of ($0.1-34.0{\mu}g/L$) turn out to be 52.7 years average age in their low concentration, ($mean{\pm}SD$) of the value of $0.10{\pm}0.02{\mu}g/L$. Among 80 people (50.8%, female: 49.2%), 16 patients (20%) have shown reaction to microscopic hematuria and 10 patients (12.5%) responded to proteinuria. In the average low concentration under 52.5 years of average age, 43 people (53%) have shown reaction to microscopic hematuria and 21 people (26.3%) are proteinuric patients out of 80 patients (male: 50.8%, female: 51.3%). In the middle high concentration of $11.8{\pm}4.82{\mu}g/L$ under the average age 51.7 years, 35 patients (53%) have responded to the microscopic hematuria and proteinuric patients are 26 people (39.3%) out of 66 people (men: 44%, women: 56%). In addition, in the concentration of $51.7{\pm}43.5{\mu}g/L$, some patients who get out of the reference value are observed as the average age of 52.0. 11 patients (78.6%) out of 14 (male: 35.7%, female: 64.3%) react to the microscopic hematuria. There show 6 people (42.8%) who turn out to be as proteinuric patients. As for the interval time, $1.67{\pm}3.71{\mu}g/L$ was the average value among 48 patients (female: 45.8%, male: 54.2%). Conclusion: We cannot see if proteinuria and hematuria directly affect abnormal results of inspection of 8,18 cytokeratin; however, we can find out that they statistically have an influence on highly generating UBC among several mechanisms. Also, although urination interval time was various every 15 minutes, we it does not affect these results.

A36 patients of a total of 60 persons show $2{\Delta}$ and less, and the rest of 24 patients show $6{\Delta}$ and less. The patient, who increase more in near distance than far distance in exophoria amount are 27 persons. The unchanging patients are 13 persons, and the patients who phoria amount decreasing are 20 persons. Like this, the patients who phoria amount unchange and decrease show more than the half. That is why convergence increases in near distance. The expected value of horizontal phoria in near distance is $3exo{\pm}3$. Only 13 patients get rid of its value, 47 satisfy its value. In AC/A value, 35 persons show under 3(1ow), 21 persons show 3~5(normal), and 4 persons show more than 5(high). By Percival's theory, 36 patients don't feel a slight asthenopia without correcting phoria. Finally, in near point of convergence 27 patients show 10cm and less, 24 patients show 11~15cm, 3 patients show 15~20cm, and 6 patients show 21~25cm. Most of them show high accommodation.

Background: Stroke patients usually experience damage to multiple functions and a long rehabilitation period. Hence, there is a large volume of patient clinical information. It thus takes a long time for clinicians to identify the patient's information and essential pieces of information may be overlooked. To solve this, we stored the essential clinical information of stroke patients in a blockchain and implemented the blockchain technology using the Java programming language. Methods: We created a mini blockchain to store the medical information of patients using the Java programming language. Results: After generating a unique pair of public/private keys for identity verification, a patient's identity is verified by applying the Elliptic Curve Digital Signature Algorithm based on the generated keys. When the identity verification is complete, new medical data are stored in the transaction list and the generated transaction is verified. When verification is completed normally, the block hash value is derived using the transaction value and the hash value of the previous block. The hash value of the previous block is then stored in the generated block to interconnect the blocks. Conclusion: We demonstrated that blockchain can be used to store and deliver the patient information of stroke patients. It may be difficult to directly implement the code that we developed in the medical field, but it can serve as a starting point for the creation of a blockchain system to be used in the field.

Background: The study evaluated the patient, lifestyle and tumor profile in patients undergoing upfront surgery for sporadic colorectal cancer (CRC) in Indian population. Materials and Methods: One hundred consecutive patients were included. Details related to their demographic profile, habits, signs and symptoms, tumor profile, further treatment and follow up were recorded. Results: The majority of the patients had colonic cancer (68%), advanced tumor stage 3 & 4 (46%), moderately differentiated tumors (70%) with absence of lymphatic invasion (60%) and metastasis (90%). Correlations between tumor location and abdominal pain (p-value 0.002), bleeding per rectum (p-value <0.001), difficulty in micturition (p-value 0.012) and constipation (p-value 0.007) were found to be statistically significant. Abdominal pain was more frequently reported in patients with metastasis (p-value 0.031). Loss of weight statistically correlated with absence of lymphatic invasion (p-value 0.047). Associations between tumor stage and alcohol intake (p-value 0.050) and non vegetarian diet (p-value 0.006); lymphatic invasion and intake of spicy food (p-value 0.040) and non vegetarian diet (p-value 0.001) and metastasis and alcohol intake (p-value 0.041) were also observed. Age and tumor grade were also correlated (p-value 0.020). Conclusions: Minimizing the adverse lifestyle factors can help in reducing the overall incidence of CRC in the Indian population.

Two-hundred and eighteen patients were taken bronchoscopy to evaluate the value of bronchoscopic diagnosis in the lung cancer patient at the Department of Thoracic Surgery of the Kyung-pook University Hospital. Ninety-eight eases of these patients were studied for possible lung cancer by bronchoscopic examination, biopsy and bronchial cytologv. The results were obtained as follows: Two-hundred and eighteen patients were taken bronchoscopy to evaluate the value of bronchoscopic diagnosis in the lung cancer patient at the Department of Thoracic Surgery of the Kyung-pook University Hospital. Ninety-eight eases of these patients were studied for possible lung cancer by bronchoscopic examination, biopsy and bronchial cytologv. The results were obtained as follows: 1) Forty-five (55.5%) of 81 cases impressed as definitive, and six (35. 3%) of 17 cases impressed as probable lung cancer were subsequently proved to have lung cancer. This represents a total of 51 cases (52. 0%) of 98 patients. 2) Twenty-six (51.0%) of 51 patients were proved by bronchoscopic biopsy and cytology. 3) The positive rates of bronchoscopic biopsy were higher in the lesions on tile intermediate bronchus, carina and main stem bronchi by bronchoscopy, and also in the hilar than in peripheral lesions by X-ray finding and in histologically undifferentiated cell carcinoma than in adenocarcinoma. 4) The positive diagnosis rates of bronchoscopic aspirate were not correlated to the locations of cancer lesions. 5) Thirty- nine percent of 51 case3 were visualized definitive tumor mass and obstructive lesions under bronchoscopy. 6) Patient of lung cancer varied in age from 27 to 77 years, with highest concentration lying in the 5th decade (43.0%). Forty-seven patients were men and 4 were women giving a proportion of men to women, 12: 1 7) Sixty-five percent of proved lung cancer patients were diagnosed as operable cases. Fifty-three percent of explored patients were resected. These results conclude that bronchoscopy is of a considerable value as a diagnostic procedure in these lung cancer patients.
