BACKGROUND: Epidural morphine has been commonly used to provide postoperative pain relief, but it has many side effects such as nausea, vomiting, respiratory depression, and pruritus. The purpose of this study was to evaluate the analgesic efficacy and side effects by combination use of epidural morphine and butorphanol. METHODS: Forty five patients were randomly divided into 3 groups. For group I, a bolus of 4.7 ml of saline and 3 mg of morphine were administered. For group II, a bolus of 4.2 ml of saline and 3 mg of morphine and 1 mg of butorphanol were administered. For group III, a bolus of 3.2 ml of saline and 3 mg of morphine and 3 mg of butorphanol were administered. Continuous epidural analgesia were administered for all groups; group I (saline 99.4 ml and morphine 6 mg), group II (saline 98.4 ml, morphine 6 mg, and butorphanol 2 mg), group III (saline 96.4 ml, morphine 6 mg, and butorphanol 6 mg) by two day infuser, 2 ml/hr. We compared the side effects and analgesic effect of the three groups for 2 days. RESULTS: The incidence of pruritus, nausea and vomiting was reduced significantly in the group II and III, but the incidence of somnolence increased in the group III. There were no significant differences in analgesic effect and the other side effects among the three groups. CONCLUSION: Above results suggest that the addition of butorphanol to morphine in epidural infusion reduce the incidence of pruritus, nausea and vomiting, but increase the incidence of somnolence.

One case of unilaterally developed acute retinal necrosis syndrome was studied with retina and vitreous from biopsy during operation through electronmicroscope pathologically and virolo gically. In photoreceptor cells, generalized necrosis was found: loss of outer segments, fragmentation of inner segments, and decrease of mitochondria in ellipsoids. Bipolar cells and axons were well preserved. Internal limiting membrane was intact, and covered by an unidentified cell. Degenerated retinal proper had various sized vacuoles. Around the intraretinal vessels, neutrophils and lymphocytes were infiltrated considering vasculitis. In ganglion cells, swelling of mitochondrias were seen, and their cell organelles were decreased, No virus particle was detected in all layers of the retina with electronmicroscope.

We rotated the nucleus up to 270 degree and dislocated it into anterior chamber through the diameter of capsulorhexis after hydrodissection by using the planned extracapsular cataract extraction. And later on we delivered the nucleus with hydroexpression using the irrigating Vectis or with rotation using a lens spatuala. As a result of this procedure, the nucleus was safely delivered in all cases without zonular rupture and vitreous prolapse.

Bronchopulmonary sequestration (BPS) is a rare congenital abnormality of the lower airway, generally characterized by blood supply received from the systemic circulation. We present a rare case of a 19-year-old man with incidentally detected BPS supplied by a branch of a pulmonary artery, rather than a systemic artery. Computed tomography showed a sequestered segment supplied by a branch of the left pulmonary artery and containing an ectopic bronchus. As chest computed tomography revealed necrosis in the sequestered tissue, infection was presumed, and the tissue was surgically removed. This may represent a very unusual occurrence, as such cases have yet to be reported in the literature.

Purpose: The purpose of this study was to describe the profile of graduates from accelerated second-degree Bachelor of Science in Nursing programs and to analyze the relative efficiency of nursing colleges using data envelopment analysis. Methods: An online survey link was emailed to the deans of nursing colleges, who were then asked to send the link to graduates of the respective colleges. The survey questionnaire included demographics, reasons for applying to the accelerated second-degree Bachelor of Science in Nursing program, employment after graduation, and nursing career satisfaction. Results: Sixty-two graduates of the accelerated second-degree Bachelor of Science in Nursing program responded to the survey. The mean age at admission was 24.28 (± 3.01) years. Reasons for applying to the accelerated second-degree Bachelor of Science in Nursing program were primarily increasing job security and using it as a stepping stone to another career. Nursing career job satisfaction was 4.81 (± 1.07) and more than 82% recommended this program. The data envelopment analysis found the average efficiency score to be 0.84 (± 0.20) and 4 nursing colleges to be relatively efficient. Conclusion The accelerated second-degree Bachelor of Science in Nursing program can be considered to be an effective means to produce quality nurses with non-nursing bachelor degrees in a short time; however, outcomes of this program need to be systematically monitored to maintain quality level. Through this, competent nurses with knowledge of adjacent studies will be added to the nursing workforce.

The malignant potential of a tumor is related to its ability to dissociate invasion and seed other sites-metastasis. In either instance, the tumor cells are confronted with a barrier signif icantly composed of type IV collagen. This type IV collagen is a major structural protein of basement membranes. Using immunohistochemical method to detect type IV collagen, intensity of stain and continuity of basement membrane at the tumor-stromal border was studied in surgical specimens from 47 colorectal carcinomas at the Pusan Paik-Hospital. Immunoreactivity was evaluated semi-quantitatively as three categories; Type-1, thick or normal basement membrane with or without minimal discontinuity; Type-2, thin basement membrane with or without moderate discontinuity; Type-3, fragmented or absent basement membrane. Also, in each case the tumor morphologic features were identified. The histologic type, differentiated grade, desmoplastic response, lymphatic and vascular invasion, lymph node involvement, tumor size and modified Dukes' stage were estabilished. Type-1 immunoreactivity was significantly observed in well-differentiated, negative lymph node, Dukes' stage B1/B2 tumors, and Type-3 was in poorly differentiated, positive lymph node, Dukes' stage C2/D. The expres sion of collagen IV in basement membrane was statistically significant correlated with differentiated grade, lymph node metastasis and modified Dukes' stage. By contrast, no statistically significant correlation was found between paucity of type IV collagen and the other parameters. The result suggest that expression of type IV collagen in basement membrane may be a useful prognostic marker, and may play a part in the invasive and metastatic process of colorectal carcinomas.

Skeletal muscle involvement has been well documented and muscular symptoms are common in patients with polyarteritis nodosa (PAN). However, the level of muscle enzyme is uncommonly elevated and overt rhabdomyolysis is very rare. We report a case of PAN presenting as rhabdomyolysis. A 22-year-old man was admitted because of fever, severe myalgia and swelling in all extremities. Laboratory investigations showed markedly increased levels of serum creatine kinase and myoglobin. There was diffusely increased muscular uptake in bone scan. Muscle biopsy from the right deltoid revealed vasculitis involving medium-sized vessel with ischemic necrosis of muscle. On angiography, saccular aneurysms were found in multiple arterities. Therapy with methylprednisolone pulse therapy and cyclophosphamide was followed by improvement of his symptoms.

BACKGROUND: Approximately two thirds of acute myeloid leukemia(AML) have recognizable clonal chromosome abnormalities. We have performed the cytogenetic monitoring of 35 de novo AML to follow the karyotype changes at diagnosis, in remission, and in first relapse. METHODS: The study is based on 35 cases of AML seen between January 1, 1996 and June 30, 1999. They were subdivided in accordance with the FAB classification and treatment response was evaluated by the National Cancer Institute(NCI)-sponsored workshop criteria. Chromosome studies were done with standard 24-48 hour methotrexate synchronization. RESULTS: The frequency of FAB M0, M1, M2, M3, M4, M5, and M6 was 1, 5, 18, 6, 3, 1, and 1, respectively. Clonal chromosome abnormalities were detected in 25 of 35(71%) in the decreasing order of t(8;21), t(15;17), +8, del(9q), etc. Thirty-one(89%) entered complete hematologic remission and 4(11%) represented partial remission. All 31 cases of complete remission had normal karyotypes. Three partial remission patients having both normal and abnormal metaphases at diagnosis and first follow-up had only normal cells after reinduction, however, in 1 case of induction failure, only abnormal metaphases persisted. In 5 of 7 relapses, karyotypes at diagnosis and relapse were identical. Two cases underwent a normal-to-abnormal change and clonal evolution, respectively. CONCLUSIONS: In this study the karyotypes were normal during complete remission, and in relapse the original aberrations returned sometimes with newly acquired clonal abnormalities. Therefore, cytogenetic study yields basic important information for understanding of cancer genetic mechanisms and molecular biologic analysis.
