PURPOSE: This study was to analyze the trends of research on school health by examining papers related to school health. METHOD: This studt was analyzed all related papers published in journals concerning school health from 2000 to 2006. The data were processed statistically by frequency, percentage and content analysis. RESULTS: Among 463 papers in 6 journals related to school health, 'The Journal of the Korean Society of School Health' had the largest number of articles. Descriptive research design was the most frequently used research design, and students were the most frequent research target. Among research writers, the professor group was largest, and schools were the most frequently used place for research. The most common sampling method was convenient sampling. The most common research instrument was questionnaire survey. Parametric statistics were the main methods of data analysis. Among the themes of school health, the adoption of nursing process frames and assessment domains occupied the largest portion. Health was the most common key concept, and the mainly used theory in the journals was factor-isolating. CONCLUSION: Through the analysis of research trends, we expect a higher level of school health research.

Sonographic detection of ureteral jets entering the urinary bladder is a well-known procedure. Color Doppler ultrasound was used to image the ureteral jets in 28 patients with unilateral ureteral calculi proved by intravenous urography. Three major findings of ureteral jets were obtained in the affected ureter with a stone: less frequency (26 patients), weak reflection (20 patients), and lower grade in length (27 patients) that were significantly different from the unaffected side in the same patient. No significant differences were found between the ureteral jets and the degree of hydronephrosis or the location of a stone. In conclusion, these results suggest that ureteral jets should be checked routinely during the procedure of color Doppler ultrasonogram in patients with possible unilateral ureteral obstruction. Color Doppler examination of ureteral jets may be a important adjunct in routine pelvic ultrasonogram especially in patients who have absolute or relative contraindications of intravenous urography.

Paranasal sinus CT is known as the most effective imaging modality in the evaluation of inflammatory sinonasal diseases and can depict the distribution, causative lesions obstructing main drainge route, and associated findings. Recently, functional endoscopic sinus surgery has been widely used for the evaluation and treatment. Before operation, PNS CT has been routinely used to evaluate the paranasal sinuses and mucociliary drainage route. The authors analyzed the PNS CT findings of 3156 cases in 1578 patients with chronic sinusitis symptoms. Sinonasal inflammatory diseases were categorized into 5 patterns according to the obstruction sites. They were 1) infundibular (10%, 316/3156), 2) ostimeatal unit (41%, 1294/3156), 3) sphenoethmoidal recess (12%, 379/3156), 4) sinonasal polyposis (30%, 946/3156) , and 5) unclassifiable (6%, 190/3156) patterns. The main causes for infundibular obstruction in order of frequency were inflammatory mucosa, enlarged ethmoidal bulla and Haller's cell. With respect to the middle meatus obstruction, is main causes in the order of frequency were polypoid lesion, inflammatory mucosa and medially deviated uncinate process. In particular, sinonasal polyposis showed one or more of the characteristic associated findings of infundibular enlargement, air-fluid level, ethmoidal sinus was bulging and bony deossification or sclerosis as well as sinonasal polypoid change. In conclusion, the inflammatory sinonasal diseases were classified into five patterns, and the causative lesions or anatomic variations were efficiently detected by the PNS CT. Furthermore, it could provide a guidance for proper management of the sinusitis including functional endoscopic sinus surgery.

The 35 patients who have suffered from myositis ossificans were investigated for 11 years. They wereposttraumatic patients, They trauma was divided into 3 groups; spinal cord injury, direct injury(fracture) andmixed type involving both. We evaluated the age distribution, the frequency of myositis ossificans, predilectionsite, bilaterality and relation between predilection site and bilaterality to the type of trauma. The results areas follows; 1. The age distribution was highest in 4th decades(12 among 35 patients). 2. In regard to distributionof 35 patients, spinal cord injury were most common (15 cases, 43%), the fracture nextly common (14, 40%) and thenmixed type (6,17%). 3. Among 51 cases of myositis ossificans, the frequency was highest in spinal cord injury(25cases, 49%), next was fracture(14, 27%). 4. The correlation between predilection site of myositis ossificans andlevel of spinal cord injury, hip is the most frequent site in thoracic injury. 6. The bilaterality of myositisossificans is 39%(20 among 51 lesions).

The ultrasound is easily available and noninvasive diagnostic method without radiation hazard. We can approachto differential diagnosis of ovarian tumors by gray sale ultrasound which can display the detailed structure ofsoft tissue. In department of radiology, Korea Veterans Hospital, 27 cases of histologically confiremd ovariantumors collected from March 1984 to February 1986 were analized. The results were as follows: 1. The agedistribution was from 13 to 72 years. 2. The histologic diagnosis of ovarian tumors(27 cases) are as follows:teratoma(14), mucinous cystadenoma(8), mucinous cystadenocarcinoma(1), serous cystadenoma (2), Krukenburg tumor(1)and malignant thecoma (1). 3. The long diameter of ovarian tumors ranges from 4cm to 28cm. In these, mucinouscystadenoma is the largest and their size are as follows; less than 10cm; 25%, 11–15 cm; 12%, 16–20 cm; 25% andmore than 20cm; 38%. 4. The ultrasonographic findings of teratoma(14) were mainly cystic (8) or echogenic(6).There were echogenic solid components showing distal acoustic shadowing or fat-fluid level within cystic masses.Echogenecity of solid masses was heterogenous. 5. The ultrasonographic findings of mucinous cystadenoma&cystadenocarcinoma(9) were unilocular cystic (3) or multilocular cystic(6). There were variable amount ofechogenic component within cystic masses. 6. Those of serous cystadenoma(2) were unilocular cystic (1) ormultilocular cystic (1). 7. Krukenburg tumor(1) and Malignant thecoma(1) were heterogenously echogenic.

BACKGROUND: Although therapeutic plasmapheresis (TP) is a useful procedure in removing pathogenic antibodies and toxic substances from the patient, adverse reactions could arise from the use of replacement fluids and anticoagulants. Comprehensive analysis on those adverse effects had been rarely reported in Korea. METHODS: We retrospectively investigated the clinical records and the TP records from 3,962 TP sessions for 581 patients between January 1995 and October 2008 at Asan Medical Center, and we analyzed the adverse reactions related to TP. RESULTS: Adverse reactions were seen in 142 patients (24.4%) in 348 TP procedures (8.8%). Citrate toxicity was most frequently seen in 83 procedures (23.9%) followed by chills in 72 procedures (20.7%), allergic reactions in 69 procedures (19.8%) and hypotension in 60 procedures (17.2%). Citrate toxicity, chills and allergic reactions were seen more frequently in the TP procedures using FFP than in the TP procedures using albumin (P=0.001). The prevalence of citrate toxicity was significantly lower in the cases where calcium gluconate was administered (P<0.001), while it was significantly higher in the patients whose hematocrit was below 28.5% (P<0.001). In terms of severity, the mild, moderate and severe adverse reactions were 36.8%, 56.3% and 6.9%, respectively. CONCLUSION: TP is a relatively safe method of treatment, but it is important to predict and prevent adverse reactions and to respond appropriately to these adverse reactions.

BACKGROUND: Propofol has a high incidence of pain with intravenous injection, and different methods have been used to minimize the incidence and severity of this pain. In this study, we have compared the effect of lidocaine pretreatment with that of ketamine pretreatment on propofol injection pain. METHODS: Ninety healthy female patients scheduled for general anesthesia were randomly divided into three groups; saline group (n=30), lidocaine group (n=30) and ketamine group (n=30). Each patient received 2 ml of pretreatment solution (normal saline, 1% lidocaine, 0.5% ketamine) via 18G angiocatheter inserted in the antecubital fossa after applying an arm tourniquet inflated to 50 mmHg. The tourniquet was released 1 minute later, followed by intravenous injection of 2.5 mg/kg of propofol. The assessment of pain was made at the induction of anesthesia and in the recovery room, and the severity of pain was classified as none, mild, moderate, severe by one observer. RESULTS: The severity and incidence of pain diminished significantly in the lidocaine group and the ketamine group compared with the saline group at the induction of anesthesia (p<0.05) and there was no significant difference between the lidocaine group and the ketamine group. We had similar results in the recovery room and one patient from the saline group and the ketamine group had no recall regarding injection pain. CONCLUSION: Intravenous ketamine pretreatment is as effective as intravenous lidocaine pretreatment in alleviating the propofol injection pain.
