Objectives: Considering high prevalence of myopia in Asian countries, social cost paid for myopia may gradually increase in Korea. However, studies for developing myopia treatment are deficient. The study was to evaluate whether the periocular acupressure with a medical massager is effective for suppressing myopia progression. Methods: This study was an investigator-sponsored, prospective, open-labeled, and superiority pre and post single-armed study. 14 myopia children aged 7-12 years wore a medical massager for 15 minutes to stimulate periocular acupoints. For 24 weeks, the participants used the device twice a day. Based on prior studies, the refraction change of naturally proceeded myopia was set as -0.38 D. The axial length change of naturally proceeded myopia was set as 0.228 mm. To assess the safety, we performed vital sign check, physical examination, visual acuity test, slit lamp examination, IOP measurement, and fundus examination. Results: The refraction and axial length of the participants increased. For 24 weeks, the change in refraction was -0.38 D at the right eye and -0.40 D at the left. The change in axial length was 0.21 mm at the right and 0.22 mm at the left. In the safety assessment, any adverse event did not occur. Conclusions: There was no significant difference between the control group and the intervention group. The effect of growth may have more contributed to our result than that of acupressure. Based on our result, a full-scale study will not be conducted.

After a vital pulpotomy in dogs' teeth, the responses of the remaining pulp tissue under hydroxides (calcium hydroxide, magnesium hydroxide, aluminium hydroxide and zinc hydroxide) were studied histologically. The class V cavities were prepared on the teeth and the pulp was amputated. Each hydroxide was placed over the amputated tissue and the cavity was sealed with zinc oxide eugenol cement. Animals were sacrificed after 3 days, 1, 2, and 3 weeks following the operation. The teeth were decalcified, sectioned and stained with hematoxylin and eosin. Microscopic examination reveals as follows; 1. Calcium hydroxide: Inflammatory change was seen in the superficial portion of the remaining pulp tissue at the 3rd day and 1st week. The incompleted calicified material began to be deposited from the canal wall at the 2nd week, and the advanced calcified material was seen at the 3rd week. 2. Magnesium hydroxide: Severe inflammatory change was seen in the superficial portion of the remaining pulp from the 3rd day and the 1st week samples. Inflammatory change was decreased at the 2nd week and the slight calcified material was deposited from the root canal at the 3rd week. 3. Aluminium hydroxide: Severe inflammatory changes were seen in the remaining pulp tissue, the blood vessel was dilated, and the odontoblasts were destroyed at the 3rd day and 1st week. The fibrous degeneration spread to the apex at the 2nd week. There was no evidence of newly formed odontoblasts or deposition of calcified material underneath aluminium hydroxide. 4. Zinc hydroxide: The micrscopic picture was destructive. A thick necrotic layer was found under the amputated surface at the 3rd day and 1st week. Granulation tissue formation as well as chronic inflammatory changes extended to the apical area in the pulp tissue. Also there were no sign of odontoblastic formation or calcified material at the 2nd and 3rd week.

Multiple facial trauma patient should be carefully treated because of severe bleeding on extraoral and intraoral wound, possibilty of airway obstruction and hypovolemic shock. Hypovolemic shock may be divided to hemorrhagic shock and non-hemorrhagic shock. Also hemorrhagic shock is divided to mild, moderate and severe shock according to the degree of blood volume depletion. Mild shock occurs in blood loss of less than 20% of blood volume and moderate shock does in blood loss of 20-40% of blood volume. And Severe shock occurs in blood loss of more than 40% of blood volume. The goal of emergency care of trauma patient is that respiration and perfusion should be recovered to satisfactory level and that normal vital sign is maintained. We reported the case of multiple facial trauma patient with severe bleeding and hopovolemic shock and metabolic acidosis who was treated with adequate supply of fluid transfusion, intubation, tracheostomy and emergency operation.

Stroke patient needs rehabilitation after receiving an acute treatment in a hospital. When stroke patient gets involved in an early discharge program, home care nurse plays a pivotal role to make them to gain a full strength and to come back to his/her prior life before he/she is sick. In spite of the importance of home care nursing intervention protocol for home care nurses to perform home care nursing autonomously, home care nursing intervention protocol for stroke patient is rarely developed. Therefore this study was conducted to develop home care nursing protocol that is applicable for stroke patients in home care nursing area. 41 home care nursing charts for stroke patients registered in home care nursing agencies from December 1st 1994 to August 31st 1999 at Y hospitals in Seoul and Won-Ju city were analyzed. 44 home care nurses who were having over three years' experience on stroke patients were participated in this study as a user validity validation group. The results of this study are as follows. 1. 28 nursing diagnoses were selected on the basis of evaluation of nursing diagnoses of stroke patients presented in a previous literature and case studies on home care nursing. 2. 17 nursing diagnoses were classified through the frequency analysis of home care nursing charts for 41 stroke patients who had received home care nursing. The order of sequence was like these: impaired skin integrity, risk for infection, nutritional deficit, impaired physical mobility, constipation, knowledge deficit, ineffective airway clearance, anxiety in family members, risk for aspiration, self care deficit, altered urinary elimination, ineffective individual coping, social isolation, risk for injury, self-esteem disturbance, impaired verbal communication, fatigue of family caregiver. 3. Based on validation on expert and user validities, 44 nursing interventions which were above ICV=.80 were chosen. 4. Nursing intervention protocols which showed above ICV=.90 were developed and were like these; pressure ulcer care, position change, preventive care for circulatory dysfunction, tube care : catheter, vital sign monitor, constipation/impaction management, artificial airway management, suction of airway secretion, environmental management : safety, and fall prevention.

Purpose: Plastic surgeons are responsible for the management of spinal cord injury patients with upper and lower extremity reconstruction, pressure sore, and wounds. Derailment of autonomic nervous systems caused by injury to the spinal cord may result in fatal autonomic dysreflexia. Autonomic dysreflexia is a syndrome of massive imbalance of reflex sympathetic discharge occurring in patients with spinal cord lesion above the splanchnic outflow(T6). It is characterized by a sudden onset and severe increase in blood pressure and is potentially life threatening. The other classic symptoms are headache, chest pain, sweating, and bradycardia. In order to lower the blood pressure, it is important to remove the noxious stimulus for autonomic dysreflexia. If such symptoms last for more than 15 minutes despite conservative interventions, antihypertension drugs are recommended. Methods: In this case study, we report an autonomic dysreflexia case that developed in a 45 year-old tetraplegia patient with sacral pressure sore. When he got bladder irrigation, his blood pressure went up very high and his mentality became stuporous. He was sent to ICU for his blood pressure and mental care. ICU care made his vital sign stabilized and his mentality alert. Results: After the patient underwent proper treatment like inotropic agent, he was transferred to the general ward and his pressure sore on sacral area was coveraged with gluteus maximus myocutaneous advancement flap. Conclusion: If treatment is not effective, the patients have to undergo sudden, severe hypertension, which can cause stroke or death. To provide safe and effective care, plastic surgeons should be able to recognize and treat autonomic dysreflexia.
