BACKGROUND: Induced hypotension is effective in decreasing blood loss and providing better visibility in the surgical field. Extensive epidural block to T4 with intravenous infusion of low-dose epinephrine allows mean arterial pressure to 50 mmHg. We investigated the effects of hypotensive epidural anesthesia comparing with normotensive epidural anesthesia during total hip arthroplasty. METHODS: 40 patients scheduled for total hip arthroplasty under epidural anesthesia were randomly divided into two groups. In hypotensive group, 0.5% bupivacaine 20cc was injected into L1-2 epidural space and if sensory block reached to T4, then epinephrine 1~5 g/min was intravenously injected with continuous infusion pump. As a result, mean arterial pressure was maintained 50 mmHg, and heart rate, 55~80bpm. In normotensive group, 0.5% bupivacaine 20cc was injected into L4-5 epidural space, and sensory block reached to T8. Therefore blood pressure was maintained within 20% of preoperative baseline. RESULTS: There was apparent difference in blood loss between two groups (hypotensive group: 259 +/- 75 ml, normotensive group: 803 +/- 144*ml) (*:p<0.05). In addition, in the case of hypotensive epidral group, transfusion was not required and CVP, heart rate were not changed postoperatively. Cardiac, renal, and cerebral function were preserved too. CONCLUSIONS: Hypotensive epidural anesthesia with low dose of epinephrine infusion is safely lowering mean arterial pressure to 50 mmHg. This technique is associated with low blood loss, reduction in perioperative transfusion requirements, and has no side effects on CNS, liver, kidney and heart function.

After coronary stent implantation, neointima formation resembles the wound healing process as it involves the sequential processes of inflammation, granulation, and remodeling. Because antiproliferative drugs and polymers of drug-eluting stents (DESs) delay vascular healing compared with bare metal stents, fibrin deposition can remain long after stent implantation, or inflammation can be excessive. Delayed vascular healing can be associated with adverse clinical outcomes including DES thrombosis or restenosis, and poor endothelization of DES neointima can accelerate neoatherosclerotic change inside the neointima, further contributing to luminal restenosis or neointimal instability. Despite the lack of correlation between pathologic and optical coherence tomography (OCT) findings, OCT assessments of neointima under various circumstances can reveal vascular responses to stent therapy. Homogeneous, heterogeneous, and layered neointima patterns can be recognized by OCT and can change with time. Homogeneous neointima might be associated with better clinical outcomes after DES implantation, whereas non-homogeneous neointima or neoatherosclerotic change can be associated with poorer clinical outcomes. However, limited data are currently available, and further studies are required to comprehensively address these questions.

This study was designed to investigate clinical characteristics and outcome of patient with suicidal attempt. A retrospective analysis by chart review of 130 cases of patients with suicidal attempt who visited emergency department of Dankook University Hospital from January 1998 to December 1998. The results were as follows; 1. The ratio of patients with suicidal attempt to total patients who visited emergency department was 0.7%. The highest suicidal attempt rates were among aged 20-39. The gender ratio is similar. 2. Suicidal attempt were more common in summer, July, Friday, evening. 3. The most common place of suicidal attempt was home. 4. Drug ingestion was the most common method of suicidal attempt. Drug used for suicidal attempt were agricultural drug including organic phosphorus and carbamate, and therapeutic drug. 5. Common motives of suicidal attempt were marriage conflict, family conflict. 6. The intensity of will to die was more strong in old aged male. 7. Suicidal attempt associated with alcohol drinking was 39.2%. 8. Common symptoms or signs of intoxication were neurological and gastrointestinal.

Dislocation involving tarsal navicular is a extremely rare injury compare to dislocation of other tarsal bone. One case of the tarsal navicular dislocation associated with subluxation of the midtarsal joint treated by open reduction and arthrodesis was reported.

In order to evaluate the clinical usefulness of maternal serum C-reactive protein measurement in early detection of infectious morbidity at term laboring women, serum C-reactive protein levels were measured in 521 healthy pregnant women : 64 who were not in labor before term, 55 who were in labor before term, 71 who were not in labor at term and 331 who were in labor at term. The frequencies of elevated serum C-reactive protein level were compared in relation to the gestational weeks, the presence or absence of labor, the status of amniotic membranes and the degree of cervical dilation. The obtained results were as follows. 1. The frequencies of women with elevated serum C-reactive protein, 0.8 mg/dl or higher and 2.9 mg/dl or higher, in 521 health pregnant women were, 12 % and 4 %, respectively. 2. C-reactive pretein levels of 0.8 mg/dl or higher were more frequent in the group of women in labor than those not in labor(5. 93 %, vs, 13.73 %, p<0.05), but the frequencies of C-reactive protein level of 2.0 mg/dl or higher were not statistically different between both groups. The frequencies of C-reactive protein level of 0.8 mg/dl or higher and 2.0 mg/dl or higher were not statistically different between the groups before term and at term, intact and ruptured membranes, latent phase and active phase of labor, respectively. 3. Before term, C-reactive protein levels of 0.8 mg/dl or higher and 2.0 mg/dl or higher were more frequent in the group of women in labor than those not in labor(23.64 vs. 4.69, p<0.001 and 12.73% vs. 3.13%, p<0.05, respectively), but those statistical differences were not seen between both group at term. Above results and review of literature suggest that serum C-reactive protein level of 2.0 mg/dl or higher may be reliable in early detection of infectious morbidity at term laboring women as well as laboring women before term, and the presence of subclinical infection should be suspected in the laboring women before term with serum C-reactive protein level of 0.8 mg/dl or higher.
