This study aims to determine the changes in health beliefs and practices of dental hygienists on infection control after having received special training on that subject. The study population consisted of dental hygienists working at the dental institutions located in Seoul and Gyeonggi areas. The intervention group and the control group each had randomly assigned 26 dental hygienists. The intervention group received training courses on infection control once a week for 3 hours, for a total of 4 training sessions. We used a survey tool to find the changes between the two groups regarding their health beliefs and practices on infection control measures. The survey was conducted prior to the training sessions, 3 months and 2 weeks after the training. The study results revealed statistically significant increases in perceived sensitivity, perceived seriousness, and perceived benefits after the training courses in the intervention group (p<0.05). A statistically significant decrease in perceived barriers was also noted in the intervention group (p<0.05). Additionally, there was a statistically significant increase in the practice of infection control in the intervention group as compared to the control group (p<0.05). Therefore, we conclude that infection control training is crucial in bringing about positive changes to the health beliefs of dental hygienists, and a structured system is necessary for continuous infection management along with training in order to improve infection control practices.

Electrocardiograms were observed in 168 patients with typhoid fever and were analyzed according to the duration of illness and hemoglobin level. The following results were obtained. 1) 124 patients out of 168 patients showed abnormal electrocardiographic findings. 2) The most prevalent abnormal findings were observed during third to fourth week of illness. 3) The lower the hemoglobin level, the higher frequency of electrocardiographic abnormalities were found. 4) Among the electrocardiographic disorders, sinus tachycardia was the most common finding and it was found in 60 cases(35.7%). The major abnormalities were ST-T change, low QRS voltage, prolongation of Q-T interval and prolongation of P-R interval: the over all incidence of these were 26.8%, 15.5%, 13.7% and 9.55 respectively. In addition to the major abnormalities, incomplete right bundle branch block (5.4%), premature ventricular contractions(3.0%) and abnormal Q wave(1.2%) were observed.

Hemophilia, a genetically determined disorder, can be divided into hemophilia A and hemophilia B. Hemophilia A, defined as a sex-linked recessive trait hemorrhagic disease of males characterized by a deficiency of factor VIII occurs about seven times more frequently than hemophilia B which is characterized by a deficiency of factor IX. The complications resulting from hemophilia occurs in virtually every system. This paper is concerned with a rare complication of hemophilia, iliacus hematoma with femoral neuropathy. On case of spontaneous hemorrhage of iliacus muscle with femoral neuropathy in hemophilia was decompressed through a small incision with sump drainage under cover of AHF(Anti-hemophilic factor) concentrated plasma cryoperecipitate followed AHF replacement therapy.

Cerebral aspergillosis is a rare condition, and like other opportunistic fungal infections, it most commonly occurs in immunocompromised patients. Because of the increasing use of chemotherapy in organ transplanta-tion, cases involving neoplasms, corticosteroid therapy, and cases of lymphoma and leukemia, the incidence of fungal infections in the brain has recently increased. Cerebral aspergillosis in an infant with normal immunity is a very rare condition, and has not been reported in Korea. We report the MR findings of this condition in an infant with normal immunity.

Ambulstory surgery in a hospital-based setting has been practiced at Yongdong Severance Hospital since August 1983. Several factors favor ambulatory surgery over the inpatient approach, first, hospital costs are decreased, second, it is less disruptive to the patient's personal life and the risk of hospital-acquired infection can be significantly decreased. The charts of 1913 patients who were anesthetized for ambulatory surgery were analyzed retrospectively to obtain better guidance for anesthetic management in ambulatory surgical patients. The results are as follows: 1) The number of patients has been increasing since 1983. 2) A total of 1913 patients were evaluated, including 660 males and 1253 females, ranging in age from 5 months to 80 years and averaging 26 years. 3) The operations performed were grouped into: gynecologic(33.9% of the cases), otolaryngologic(33.7%), orthopaedic(10.4%), etc. The most frequent procedures were diagnostic dilation and curettage(23.7%) and excision(17.6%). 4) General anesthesia was performed for 852 patients(44.5%) and the anesthetic agents administered were intravenous narcotics in 360 cases, halothane-N2O-O2 in 289 cases, enflurane-N2O-O2 in 67 cases, etc. Nongeneral anesthesia was included regional nerve block in 76 cases(4.0%) and local infiltration in 985 cases(51.5%). 5) Anesthesia lasted less than one hour in 79.2% of the cases. Recovery time lasted less than one hour in 88.0% of the cases. 6) Only one patient was admitted for an anesthetic reason which was aspiration pneumonia. Seventeen patients were admitted for surgical reasons such as fever, bleeding, etc. From the above results, we believe that anesthetic care for ambulatory surgical patients can be provided safely and cost saving. Safety is an attitude, and when good practice is followed in selection of patients with careful preanesthetic evaluation and careful anesthetic technique, there is no reason to expect more complication than under the circumstance of hospitalization.

Fibrous dysplasia of bone is an uncommon condition of unknown etiology in which the bones become progressively thicker and lose their normal structure. The skull and the bones in other parts of the body are involed in a process characterized by small areas of bone destruction or massive sclerotic overgrowth. They appear denser, although actually are softer, and give a rather homogenous, smeary impression. There may be cyst like areas within the large, dense, homgenous-appearing amorphous bone. Although the skull may be the only area of involvement it is not uncommon to have similar but more cystic appearing lesions in many other bones. The authors report two cases of fibrous dysplasia involving frontal, orbital roof, ethmoid, zygoma and sphenoid bone in the left by which disfiguration of appearance of the face was resulted in association with exophthalmus.

There is some controversy regarding the effect of general inhalation anesthesia on platelet function. In 20 patients undergoing long operations over 3 hours, and anesthetized with either nitrous oxide-oxygen and enflurane (A group) or nitrous oxide-oxygen and halothane (B group), we could not find any clinically significant impairment of coagulation. Platelet functions were consecutively evaluated on the samples collected at preinduction, during anesthesia (3 hours) and at postoperation (24 hours) using an aggregometer and several aggregating agents including ADP, epinephrine, collagen and ristocetin. There were no statistically significant changes between the maximum aggregation rate of preinduction and that duirng anesthesia in either group.

Reptiles are used for various purposes these days, including public exhibits, medicinal applications, and as laboratory animals. As the international exchange of reptiles has gradually increased, more people have had the opportunity to come in contact with these animals. Snakes typically live in the rhizosphere where various bacterial strains exist and as such they can lead to opportunistic human diseases. When snakes are encountered in veterinary medicine, it is necessary to monitor their microflora. Native microflora of reptiles imported from other countries has not yet been reported in Korea. In this study, oral and cloacae samples were collected from 18 Burmese pythons transported from Vietnam. The specimens were incubated at 37degrees C for 18 h to produce colony growth under aerobic condition and isolated colonies were then identified using a VITEK automated identification system. There were fourteen types of aerobic bacteria isolated from both oral and cloacae samples, nine from only oral specimens, and fifteen from only cloacae specimens. Most bacteria isolated were opportunistic pathogens of humans which therefore have the potential to induce disease in people. Based on the microflora and the prevalence of bacterial strains in snakes, quarantine procedures for reptiles transported internationally should be strengthened. Characterization of the microflora of reptiles with the potential to induce zoonosis should be performed in those used as laboratory animals and to prevent zoonotic outbreaks in the general population as well as among veterinarians.
