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: The Purpose of this study was to explain the effects of aromatherapy massage on the preoperative anxiety of hemorrhoidectomy patients, and to provide the effective and holistic nursing care to them. METHOD: The research design was a nonequivalent control group non-synchronized design. The data were collected during the period from November 1 to November 30, 2003 at K-Hospital in Seoul. The subjects were fifty patients who were to have a hemorrhoidectomy under general anesthesia. They were assigned to two groups, 25 subjects to the experimental group and 25 subjects to the control group. The State Anxiety Inventory tool was used to measure state-anxiety on all patients the day before surgery. Systolic and diastolic blood pressure, and pulse rate were measured on the day before surgery and the preoperative period. The experimental group received aromatherapy massage on the hand with lavender oil. Data were analyzed by x2 test, independent t-test, paired t-test. RESULTS: 1. Hypothesis 1, that the level of preoperative state-anxiety of the experimental group who received aromatherapy massage would be lower than that of the control group who did not received aromatherapy was supported(p=.047). 2. Hypothesis 2was that the Physiological index of the preoperative anxiety of the experimental group who received aromatherapy would be lower than that of the control group who did not received aromatherapy. The 1st subhypothesis that "the level of the preoperative systolic and diastolic blood pressure of the experimental group would be less than that of the control group" was not supported. CONCLUSION: Aromatherapy massage can be regarded as a partially effective nursing intervention that relives the preoperative anxiety of surgical patients and stabilizes vital signs.

BACKGROUND: With the rapid increase in the elderly population and the ensuing increase in osteoporosis and subsequent fractures, there has been a rise in socioeconomic costs. This study evaluated the relationship between osteoporosis and physical function in 66-year-old Korean women. METHODS: All of the 193 Korean women aged 66 years were recruited from life-transition health examinations from May to December, 2007. Background information was collected through a self-administered questionnaire; and height, weight, and waist circumference were measured. Bone mineral density of the lumbar spine was measured with the Dual Energy X-ray Absorptiometry and the 'timed up and go (TUG)' and 'one-leg balance (OLB)' tests were administered. Risk factors for osteoporosis were analyzed by correlation coefficients and binary logistic regression analysis. RESULTS: The prevalence of osteoporosis for 66-year-old women was 25.9%. A short stature and lower body mass index (BMI) were associated with osteoporosis of the lumbar spine. A longer time to complete the TUG test (>10 second) was associated with a 4-time higher prevalence of lumbar osteoporosis, which was not observed with the OLB test. CONCLUSIONS: One out of four 66-year-old Korean women had osteoporosis. A longer TUG time, short stature, and lower BMI were associated with osteoporosis.

TMJ internal derangement has been treated by the conservative methods and the surgical methods according to the clinical state. There are several surgical methods for treatment of TMJ internal derangement, such as disk repositioning and repair, diskectomy with and without grafts, articular surface contouring, high condylectomy, condylotomy, and arthroscopic surgery etc. Especially, it has been reported that the condylotomy produced the increase of the joint space, the pain relief, the elimination of the joint dysfunction due to the antero-inferiorly movement of the condyle, and the condylar morphologic change resulted from the progressive remodeling in TMJ without the surgical intervention within the TMJ. We have performed EVRO(extraoral vertical ramus osteotomy) to the 5 patients diagnosed as ADDWR(Anterior disk displacement with reduction) from June 1997 to December 1997 in the Chin-Hae military hospital. We diagnosed them with MRI and clinical examination. And we compared the preoperative symptoms with postoperative 2 months symptoms. They were compared by Helkimo index, mandibular mobility index, and pain scale. Anamnestic Index(Ai) was changed from 2.0 preoperatively to 1.2 postoperatively, clinical dysfunction score from 11.8 to 2.8, and Clinical Dysfunction Index(Di) from 2.8 to 1.2. The pain scale of the affected side was changed from 4.4 to 2.6 and that of the non-affeted side from 2.2 to 2.6. The maximal mouth opening was changed from 35.2mm to 40.9mm, right lateral excursion from 7.8mm to 8.0mm, left from 8.8mm to 7.0mm, and protrusion from 6.2mm to 6.2mm. In these results, we could not expect any excellent improvement of the clinical symptoms during the immediate postoperative periods. But we could observe the disappearance of the joint noise and the improvement of the clinical dysfunction score. On the basis of the results of the previous investigations about condylotomy effect which presented the condyle position were changed antero-inferiorly in the articular fossa during the immediate postoperative period, the displaced condyles may prevent wide mouth opening. Therefore it is elucidated that the improvement of the maximal mouth opening and other functions were restricted during the immediate postoperative periods. After long term follow-up period, the symptomatic and functional improvement will be expected by the passive repositioning of the proximal segment. We report the preliminary results with the related references.

BACKGROUND: Skin thickness for parameter of skin aging has been analysed with various methods. Skin thickness variations between the young and the old has been studied with various methods such as biopsies, calipers, micrometers, computer tomography, ultrsonography. But none of these methods evaluates skin thickness exactly. OBJECTIVE: For the evaluation of age-dependent skin thickness changes, we compared the skin thickness of an old-aged group and a young group with 20MHz-ultrasonography. METHODS: In order to identify the skin thickness variation between different age groups, 60 subjects, 30 aged 23-33, and 30 over 60, were studied with 20MHz-high frequency ultrasonogrphy (Dermascan C, Cortex Technology, Hadsund, Denmark) on fourteen skin sites. This machine was designed to measure the thickness from the top of the epidermis to the bottom of the dermis. After storage of cross-sectional skin imaging, skin thickness was calculated with a computer assisted image-analysis program. Skin thickness of the old was analysed by age, sex, height and weight.

A case of multiple trichilemmal cysts (TC) is presented. TC is known to be a kind of keratinous cyst with lining cells showing trichilemmal keratiniration. A 63-year-old female patient presented with a 30 year duration of increasing in size and number of twenty five nodular lesions on the scalp. All twenty five TC on the scalp were totally excised and examined microscopically. However, the evidence of proliferation or malignant change like the previous case reports was not found in our case.

The clinical data of 27 patiets with hypophosphatemic rickets treated with phosphate and 1alpha-hydroxyvitamin D were analysed retrospectively. The median age at diagnosis was 4 years, and the main clinical manifestations were bowleg and short stature. Among total 24 families, 5 families (21%) had X-linked dominant mode of inheritance, 1 family (4%) had autosomal dominant mode and 17 families (71%) had no family history, The serum phosphorus concentration rose from initial value of 2.7+/-0.13mg/dl to 3.5+/-0.19mg/dl. The serum alkaline phosphatase was reduced from 871+/-63IU/L to 393+/-41IU/L. Healing of rickets was demonstrated by radiography. Patients treated for at least two years before the onset of puberty had an increase in the mean height SD score from -1.58 to -0.79. Orthopedic surgeries for severe lower extremity deformity were performed in 11 patients, of whom 8(73%) were dignosed over 5 years of age. Complications of therapy were as follows; 12 patients (44%) developed more than one episode of hypercalciuria, 5 patients (19%) developed more than one episode of hypercalcemia, and nephrocalcinosis was noted in 5(33%) out of 15 patients by renal ultrasound. The group with nephrocalcinosis had a higher incidence of hypercalemic episodes than the group without nephrocalcinosis. In conclusion, treatment of hypophosphatemic rickets results in healing of rickets and acceleration of growth, and we must evaluate complications of therapy such as hypercalcemia and nephrocalcinosis.

The clinical picture in severe cases of pandemic (H1N1) 2009 influenza is markedly different from the disease pattern seen during the epidemics of seasonal influenza as many of those affected were previously healthy young people. Current predictions estimate that during a pandemic wave, 12~30% of the population will develop clinical influenza (compared with 5~15% for seasonal influenza) with 4% of those patients requiring hospital admissions and one in five requiring critical care. Until July 6, 94,512 people have been infected in 122 countries, of whom 429 have died with an overall case-fatality rate of <0.5%. Most of the confirmed cases of S-OIV (Swine- Origin Influenza A Virus) infection have been characterized by a self-limited, uncomplicated febrile respiratory illness and 38% of the cases have also included vomiting or diarrhea. Efforts to control these outbreaks are based on our understanding of novel S-OIV (Swine-Origin Influenza A Virus) and the previous influenza pandemics. So, this review covers the experience with S-OIV (Swine-Origin Influenza A Virus) for the admission and background data and the clinical presentation, diagnosis and treatment of H1N1 in pediatric patient with S-OIV (Swine-Origin Influenza A Virus) at YUMC, 2009.

The authors examined the induntivity of sister chromatid exchanges (SCE) in peripheral lum-phocytes on the personnel working in the operating room and analyzed the factors associated with it to obtain data for their monitoring health status. The results obtained were as follows; 1) Average inductivity of SCE in peripheral lymphocytes of operating room perssonnel exposed to anesthetic gases was 7.85 per cell; it was significantly higher than in those who were not exposed (p< 0.05). 2) The inductivity of SCE in peripheral lymphocytes by age group and exposure duration was not statically significant (p<0.05). 3) The inductivity of SCE in the subjects with a smoking habit was significantly higher than those without a smoking habit (p<0.05). 4) There was no significant difference in the inductivity of SCE between the subjects with a drinking habit and those without it (p>0.05). 5) It is possible that the high inductivity of SCE in operating room personnel who both with drink and smoke was due to more the influence of their smoking than their drinking.
