BACKGROUND: Ketamine use in emergency room has been increased. It has rapid onset of action and appropriate duration of action. It does not need endotracheal intubation and produces potent analgesia, sedation, and amnesia. The object of this study is to determine the safety and the degree of physician's satisfaction in relation to ketamine use. MATERIALS AND METHODS: This is a prospective study using protocol. Pediatric trauma patients who need sedation were given IM ketamine(4mg/kg) and atropine(0.01mg/kg) in a same syringe. Monitoring of patients was done by EM residents and complications of ketamine use were recorded. Physician's satisfaction was also recorded after the procedure. RESULTS: Intramuscular ketamine was administered 54 times, mainly for laceration repair. Physicians completed protocol for 51 of treated children. The median time for onset of sedation was 6.5+/-2.4 min, and duration of action was 32.4+/-10.8 min. Hypersalivation occurred in 9.8%(n=5); random movement 3.9%(n=2), emesis during procedure(n=1), emesis at home(n=1), and transient oxygen desaturation(n=1). All were quickly identified and treated without specific airway management and sequelae. Of 84% of physicians was satisfied with ketamine use for pediatric sedation. CONCLUSION: Intramuscular ketamine can be administered safely and satisfactorily in emergency room to facilitate pediatric procedures in conjunction with a defined protocol and appropriate monitoring.

Radiometals, with their favorable decay properties and rich coordination chemistry, have found widespread applications inboth diagnostic and therapeutic nuclear medicine. To ensure effective utilization, radiometal-based radiopharmaceuticals are designed to target specific organs or cells. Radiometals are primarily produced in cyclotrons or reactors using stable isotopes as raw materials. Many countries, including Korea, are pursuing self-sufficiency in radiometal production at thegovernment level. This review examines the current production and supply status of raw materials for key radiometalsthat are either actively used or expected to see a significant demand growth in the future in Korea.

The transesophageal echocardiography (TEE) has been used for the assessment of right and left ventricular function, valvular structure and function, regional wall motion abnormalities and localization of intravascular catheters, cannular and prosthesis. We inserted the pulmonary artery catheter (PAC) under the guidance of intraoperative TEE because of the difficulty of placing PAC with the pressure tracing method in two patients. The PAC was inserted from right atrium to right ventricle with the basal four chamber view and advanced to pulmonary artery through pulmonary valve with the longitudinal view of TEE. We observed typical pulmonary arterial wave form to confirm the correct position. We suggest that the TEE can be used for successful placement of a PAC to facilitate manipulation of the catheter as an alternative method in the patients whose PAC can not be positioned with the pressure tracing method.

We evaluated the relationship between the surgical success of idiopathic macular hole and sex, age, duration, epiretinal membrane, preoperative visual acuity, size of the hole, and surgical method. Of all 25 eyes in 23 patients, 14 eyes(56%)showed anatomical success(disappearance of the hole), and 17 eyes(68%)functional success(the final visual acuity of 0.15 or more with more than one line improvement). There were statistically significant differences of anatomical(p=0.001)and functional success(p=0.020)between the Group I where its macular hole was less than one-fourth of the optic disc in size and the other group, and anatomical success(p=0.039)between the group with the age of less than 70 years(Group A)and the other group. In Group I, anatomical and functional success were both 92%(11 eyes/12 eyes). In Group A, anatomical and functional success were 72%(13 eyes/18 eyes)and 77%(14 eyes/18 eyes), respectively, and there was statistically significant relationship between size of the hole and anatomical success(p=0.024), and difference of anatomical success between the group with duration of less than 6 months and the other group(p=0.023). Good surgical result may be expected in the idiopathic macular hole of the age of less than 70 years with about 350 micrometer or less in size and duration of less than 6 months.

A case of a 21-year old female with Maffucci's syndrome is presented where the patient developed multiple cutaneous spindle-cell hemangioendotheliomas. She had multiple pea to walnut sized, non-tender, normal skin colored or slight bluish nodules and bony mass-like lesions on the left upper extremity and hand. A histological examination of the lesions showed that they were composed of irregularly dilated, thin walled cavernous blood spaces containing phleboliths and collapsed vascular spaces separated by spindled fibroblastic cells. Radiologically, the bony lesions showed radiolucent densities with calcified spots within the second proximal phalanx and metacarpal bone of the left hand, which were consistent with enchondromas.
