OBJECTIVES: To determine the complaint rates of musculoskeletal symptoms and understand the related factors of musculoskeletal symptoms in nurses and radiological technologists wearing a lead apron for radiation protection. METHOD: The study subjects were 192 nurses and radiological technologists who work at the cardiac catheterization room or angioroom in the department of radiology. A self-recording questionnaire was used to investigate the general characteristics, occupational characteristics, characteristics related to wearing a lead apron, and subjective musculoskeletal symptoms designed by the National Institute for Occupational Safety and Health (NIOSH). RESULTS: Complaint rates of musculoskeletal symptoms by NOISH were 51.0% in the upper /lower back, 49.0% in the shoulder, and 47.9% in the leg/knee/ankle. From multiple logistic regression analysis, musculoskeletal symptoms of the shoulder were influenced by two-piece type apron and long time wearing an apron, symptoms of upper/lower back by long time wearing an apron, sex, higher average working hours per a day and short resting time, symptoms of leg/knee/ankle by long time wearing an apron, working career at the present department (cardiac catheterization room or angioroom) and short resting time. CONCLUSION: The complaint rates of the musculoskeletal symptoms were affected by the characteristics of wearing a lead apron for radiation protection such as wearing time and apron type. Therefore, it is suggested that the workers who are wearing an apron need the proper wearingtime and resting time, and suitable apron type and size for the body.

Urinary cytology has become an essential element in the diagnosis and management of transitional cell carcinoma(TCC) of the urinary tract. It has the advantage of being noninvasive, inexpensive, and easily accessible. Besides that it can even detect malignancy when unsuspected at cystoscopy. We report a retrospective review of urine cytology in the diagnosis of 83 TCC cases that underwent 295 cytologic evaluation. All patients had biopsy-proven TCC of the bladder, ureter and renal pelvis. The overall inci- dence of the positive cytology cases was 66.2%. To define the cytologic features of tumor cells, we tried to use three cytologic gradings such as "grade 1", "grade 2", and "grade 3" according to the cytologic degree of anaplastic neoplastic cells. These cytologic gades of TCC were relatively well correlated with the histologic grade and tumor invasiveness. This result suggests that the recognition of characteristic cellular features of TCC can suspect the histologic grade and tumor stage. The false negative TCC cases were 78.9%. They showed severe inflammatory or bloody background and a few neoplastic cells. Therefore, a cautious approach for accurate interpretation, personal experience, and proper fixation and processing could expand the role of urinary cytology.

A 36 year old infertile was diagnosed endometrial adenocarcinoma by endometrial biopy due to vaginal bleeding. She was characterized by obesity, hirsutism and infertility. Diagnosis was confirmed endometrial adenocarcinoma(Geade I) associated with polycystic ovarian disease postoperatively. We experienced this case and so report this case with a brief review of literatures.

Fetal echocardiography is used by means of decleration of fetal cardiac anaztomy, to estabilish the diagnosis of congenital heart disease in utero. We attemped fetal echocardiography to ninty three pregnant women after intra uterine period 24 weeks, and estimated cardiac circumference, cardiac axis, pulmonary atery root diameter, arortic root diameter, diameter of inferior vena cava, diameter of superior ve studied how these estimates associate with following gestational na cava, and fractional shortening of ventricles. We ages. Cardiac axis was on the average 37.28 degree and cardiac apex was located in anterior left side of chest area. Aortic root diameter was 0.227 GA-0.043mm (GA=gestational age) at systolic phase, 0.203 GA+0.421mm at diastolic phase. Pulmonaly root diameter was 0.271 GA-0.029mm at systolic phase, 0.251 GA-0.067mm at diastolic phase. Thoracic aorta diameter was 0.195 GA+0.109mm at systolic phase, 0.198 GA+0.794mm at diastolic phase. Fractional shortening was 0.24 (1 Standard Deviation=0.11) in right ventricle, 0.23(1 SD=0.154) at left ventricle, and so ratio of right and left ventricle was 1.04(1 SD=0.51). Once normal fetal cardiac anatomy is understood, structural defects and/or alternation of function can be evaluated antenatally.

Takotsubo syndrome, also known as stress-induced cardiomyopathy, is a transient cardiac syndrome that mimics acute coronary syndrome. This condition should be suspected if the patient presents with chest pain after intense emotional stress, accompanied by an abnormal electrocardiogram, elevated levels of myocardial enzymes, and left ventricular apical akinesia on echocardiography. Coronary angiography should be performed for prompt differentiation from ischemic heart disease. A 77-year-old female presented with traumatic multiple fractures of the left sixth and seventh ribs resulting from a violent strike. Clinical findings of physical examination, laboratory tests, electrocardiogram, and coronary angiography provided the diagnosis of Takotsubo syndrome. We performed conservative management including pain control, and the patient was uneventfully discharged seven days after admission.

We, at Department of Orthopedic Surgery, College of Medicine, Pusan National University, applied epiphyseal distraction as a method of limb lengthening, using unilateral one-plane pin fixator(ORTHOFIX) and bilateral multi-plane ring fixator(SEQUOIA) to three children with limb length discrepancies and angulation deformity due to injury of epiphyseal plate, and obtained following results. l. At first case, on whose distal femoral physis, bone bridge occupied about 20% of total epiphyseal plate and distributed mainly on the lateral side. At 10 days of distraction, epiphysiolysis occurred from the lateral side at first and angulation deformity was corrected. Epiphysiolysis on the medial side of physis appeared apparently after 60mm distraction. Bone lengthening of 4.2cm and correction of 25 valgus deformity were achieved after 72mm distraction for about 10 weeks. The percentage of increase in the initial length achieved was 11.67% and healing index was 27.86. 7 months later, loss of lengthening of 2.7cm was observed and it was considered that this was due to relatively short corticalization phase. 2. At second case, on whose distal tibial physis, bone bridge occupied about 40% of total epiphyseal plate and distributed on the medial side. At 10 days of distraction, epiphysiolysis occurred on the medial side of the epiphyseal plate, but not on the lateral side and instead of further lengthening, valgus deformity of the ankle appeared. It was thought that asymmetric distraction was attributed to the difference between the force applied on the medial side and that applied on the lateral side of the epiphyseal plate by unilateral one-plane pin fixation. 3. At third case, on whose distal tibial physis, bone bridge occupied about 75% of total epiphyseal plate. No epiphysiolysis occurred. there was a difficulty in observation of epiphysiolysis because ring fixator was overlapped with the epiphyseal plate on radiographs.

Bone injuries of the extremities can be found in 0.2-2% of all living newborns. The most common location of the fracture was clavicle, and followed by humerus, femur in orders. Fractures of the femur are relatively rare. Authors have analyzed 9 cases of the femoral shaft fractures in the newborns, treated at Severence Hospital from January 1985 to March 1992. Seven cases were born by Cesarean section, two cases were by normal spontaneous vaginal delivery. Vertex presentation were three cases, breech presentation were five cases, and transverse presentation was one case. The mean birth weight was 2.93kg and four cases were born in prematurity. The location of fracture were seven cases in proximal shaft, one case in mid shaft, and one case in distal shaft. The type of fracture were all spiral fracture except two fractures. Five cases were treated by splint and 4 cases were treated by traction method. No further immobilization was needed for 8 cases but two weeks long leg cast after splint was applied for one case. Two cases of complication were noted. Skin necrosis developed due to the traction to the popliteal fossa and minimal anterior angulation of femora, and no functional deficit were found, but bony protrusion of proximal femora were palpated.

Severe sepsis and septic shock are the main causes of death in critically ill patients. Early detection and appropriate treatment according to guidelines are crucial for achieving favorable outcomes. Endotoxin is considered to be a main element in the pathogenic induction of gram-negative bacterial sepsis. Polymyxin B hemoperfusion can remove endotoxin and is reported to improve clinical outcomes in patients with intra-abdominal septic shock, but its clinical efficacy for pneumonic septic shock remains unclear. Here, we report a case of a 51-year-old man with pneumonic septic shock caused by Pseudomonas aeruginosa, who recovered through polymyxin B hemoperfusion.

Congenital dyserythropoietic anemia Type II (herditary erythroblatic multinuclearity with positive acidified serum test; HEMPAS) is characterized by binuclearity, multinuclearity, pluripolar mitoses, karyorrhexis of normoblasts, and the presence of abnormal antigens on the red cells. We experienced a case of HEMPAS in a 2 month old girl patient who had an intermittent fever, abdominal distention with palpable liver & spleen, and generalized jaundice. The blood analysis revealed anemia, and thrombocytopenia. Peripheral blood smear showed an averge of 6 mature normoblast per 100 leukocyte count. The red cells showed moderate anisocytosis, poikilocytosis, irregularly crenated, contracted cells and occasional spherocytes. The leukocytes showed relative lymphocytosis, and there were occasional villous lymphocytes. The marrow smear showed abnormality in erythroid series. About ten percent of the erythroblasts showed 2~7 nuclei or lobulated nuclei. The mitotic forms of the erythroid precursors were also increased in frequency. The M:E ratio was 1:3.2. Blood culture on this patient showed a pure growth of Coxiella burnetti. Medical treatment with Doxycycline and Rifampin was performed. After treatment, she became afebrile showing improved general condition with decreased size of liver & spleen. In spite of clinical improvement, she died suddenly 3 weeks after initial treatment.
