BACKGROUND: The perfect preanesthetic medication and its ideal route of administration are still debated. Transmucosal administration of midazolam has been of interest because of the rapid, reliable onset of action, predictable effects and avoidance of injections. Because many medications are well absorbed from the mucosa, we conducted a randomized, prospective, blinded study to compare acceptance and efficacy of intranasal and sublingual administration of midazolam as a preanesthetic medication in children. METHODS: One hundred twenty eight patients aged 0.5-12year were stratified by age: 38 infants and toddlers, 0.5-3yr; 48 preschoolers, 3.1-7yr; and 42 school age, 7.1-12yr. They were randomized to received 0.2 mg/kg of midazolam in the nose or under the tongue. Hemoglobin oxygen saturation by pulse oximetry and sedation score were recorded before drug administration, at 2.5min intervals for 15min, at separation from parents and during induction with enflurane in O2. Retention time of sublingual drug and duration of crying were recorded. RESULTS: The incidence of crying at the time of administration of midazolam was greater following intranasal compared with sublingual administration(60% vs 17%, p<0.05). Within age groups, only infants and toddlers showed a significant difference in the incidence of crying between treatment groups. Significant changes in sedation occured in both groups from 2.5min after administration. CONCLUSIONS: Sublingual midazolam is better accepted than intranasal midazolam as a preanesthetic sedative in children.

Injury of diaphragm mainly occur in penetrating, crush and blunt injuries to the lower chest or upper abdomen, and it is most often secondary to automobile accidents. Diaphragmatic rupture is most frequent in blunt chest trauma and the rate is below 1% of them. Traumatic rupture of the diaphragm is responsible for the herniation of abdominal viscera. Physical finding and radiographic sign of diaphragmatic hernia is nonspecific and misreading. Therefore, the diagnosis of traumatic rupture of diaphragm may be difficult during the early period after the injury, especially when clinical features are dominated by associated injuries. Emergency surgical management is necessary when it is complicated with serious complication. We experienced the case of traumatic diaphragmatic hernia detected after the operation of femur fracture. The patient was injured by motor vehicle accident 6 days before the operation of the femur fracture. There was no specific symptom and sign and the manifestation of the diaphragmatic hernia. in radiographic studies until operation of the femur fracture was done. Diaphragmatic hernia was confirmed by chest X-ray and arterial blood gas analysis after operation of the femur fracture. The repair of the diaphragmatic hernia was directly performed after the diagnosis. The prognosis was favorable, and she was discharged to ward from intensive care unit after 1 day of operation. We must consider the possibility of traumatic diaphragmatic hernia in the patient who have the history of blunt chest or abdominal trauma.

One of the goals of anesthesia is complete, comfortable and rapid recovery without sequelae from anesthesia. We compared the recovery pattern between anesthesia with propofol and thiopental/isoflurane. The fifty patients undergoing emergency appendectomy were allocated randomly to receive one of the anesthesia with propofol or thiopental/isoflurane. All of the patients were also given fentanyl, atracurium in equivocal dosage per weight and 50% N2O. Group 1(patient No; 25) was received anesthesia with fentanyl, atracurium, N2O and continuous injection of 6~12 mg/kg/hour of propofol. Group 2(patient No; 25) was received anesthesia with thiopental, fentanyl, atracurium, N2O and 1~2 MAC(minimal alveolar concentration) of isoflurane. We studied the duration of return of self respiration from discontinuation of anesthetics and recovery pattern in time sequence. The results were as following; The group 1 compared with group 2 at early recovery phase. 1) The duration of return of self respiration from discontinuation of anesthetics retured more rapid. 2) Emergence time was more rapid. 3) Postoperative sequelae(nausea, vomiting, sedation, drowsiness, memory dysfunction, pain) rate was less severe. But at recovery phase after 24 hours, there were no significant difference in postoperative sequelae and recovery condition in both groups. Therefore, we concluded that propofol is better than thiopental/isoflurane for anesthesia of emergency appendectomy in view of early recovery pattern.

To investigate effects of cytokines on rheumatoid synovial cells, proliferation and expression of cytokine and metalloproteinase genes were studied with the primary culture of rheumatoid synovial cells which was treated with TNF-alpha, GM-CSF, TGF-alpha, PDGF and IL-B. By [3H] thymidine incorporation assay, TGF-beta and PDGF increased proliferation of synovial cells by 1.5 and 2.5 folds respectively. Cytokine gene expression was assessed by RT-PCR. Rheumatoid synovial cells expressed constitutively TGF-beta and IL-B at a high level and IL-1B, GM-CSF, and MIP-1a at a relatively low level. TGF-beta, GM-CSF and PDGF increased IL-B expression. Expression of pro-inflammatory cytokines and chemokines was increased by GM-CSF and PDGF. Both GM-CSF and PDGF increased the expression of IL-1B, GM-CSF MIP-la and IL-8. In addition, GM-CSF enhanced expression of TNF-alpha. Stromelysin and collagenase are the major proteinases responsible for destruction ot joints in rheumatoid arthritis (RA). These genes were expressed constitutivefy in rheumatoid synovial cells. In summary, PDGF and GM-CSF may piay an important role by inducing or increasing expression of IL-1B, TGF-beta and PDGF by increasing proliferation of rheumatoid synovial cells.

Background: Single room isolation with contact precautions is widely regarded as a fundamental strategy to prevent the transmission of multidrug-resistant organisms (MDROs). However, its implementation demands substantial resources, limiting its universal application to all MDROs. In this study, we assessed the effect of discontinuing single room isolation for vancomycin-resistant Enterococcus (VRE). Methods: This is a retrospective, observational study conducted at a single 750-bed tertiary center. We conducted an interrupted time series analysis to compare incidence rates and trends of new-onset VRE colonization and bacteremia during the one year before and after the strategy change on January 1, 2023. Results: Single-room occupancy decreased from 79.7% pre-intervention to 23.6% postintervention (P < 0.001). The incidence rate of new-onset VRE colonization was 0.452 and 0.535 per 1,000 patient-days in the pre- and post-intervention periods, respectively, with no statistically significant difference (P = 0.202). However, there was a slightly increasing trend (0.036 [95% confidence interval, −0.002, 0.074] increase per month, P = 0.066). The new-onset VRE bacteremia incidence rate was not differed in incidence (0.060 and 0.055, P= 0.571) or trend (P = 0.720). Conclusion Our study suggests that discontinuing single-room isolation for VRE patients may not affect the incidence of new-onset VRE bacteremia, but caution is needed due to the potential increase in colonization.

The occurrence of the colonic obstruction secondary to colorectal carcinoma (CRC) has been reported in 7~30% of the CRC patients. It is generally believed that obstructive CRC is associated with a poor prognosis with respect to operative mortality and five-year survival. A series of 1064 cases of the CRC treated surgically at Asan Medical Center from June 1989 to December 1996 has been analyzed to compare clinicopathological findings between obstructive and non-obstructive CRC and to evaluate surgical treatment options in obstructive CRC. Complete obstruction was present in 49 cases (4.6%). There were no differences between obstructive and non-obstructive CRC in tumor location, size, Dukes' stage, and differentiation. In forty-nine obstructive CRC cases, primary resections were performed in 29 cases after peri-operative bowel decompression. In this group, right colon cancer was more prevalent than staged operation group (45% vs. 5%, P<0.05) and hospital stay was significantly short (16 days vs. 38 days, P<0.05). Postoperative complication rate was higher in staged operation group (65% vs. 28%, P=0.01). It may be due to stoma related wound complication. In obstructive left colon cancer, there was a significant difference in complication rate between primary resection and staged operation (P<0.05). Overall 5-year survival rate were 66% and 53% in non-obstructive and obstructive group, respectively. Survival rate according to the Dukes' B and C stages did not show statistical differences, either. Conclusively, primary resection is preferred to the obstructive CRC when supportive care, preoperative bowel decompression, and intraoperative colonic irrigation were performed adequately.
