Predisposing factors for venous thrombosis can be identified in the majority of patients with established venous thromboembolism (VTE). However, an obvious precipitant may not be identified during the initial evaluation of such patients. In the present case, a 47-year-old female presented to the emergency department of our hospital after ingesting multiple drugs. She had no VTE-related risk factors or previous episodes, nor any family history of VTE. After admission to the intensive care unit sudden hypoxemia developed, and during the evaluation cerebral, renal, and splenic infarctions with pulmonary embolisms were diagnosed. However, the sources of the emboli could not be identified by transthoracic echocardiography or computed tomography angiography. Protein C deficiency was identified several days later. We recommend that hypercoagulable states be taken into consideration, especially when unexplained thromboembolic events develop in multiple or unusual venous sites.

2.Availability of end-tidal carbon dioxide on change in stroke volume in spontaneous breathing subjects
Journal of the Korean Society of Emergency Medicine 2019;30(2):132-139
OBJECTIVE: Stroke volume (SV) measurements have been used to guide fluid management. Noninvasive, indirect, and convenient measurements of the SV for fluid therapy are required for most patients during spontaneous breathing (SB). On the other hand, the preferred method for an indirect prediction of the SV is unclear. This study examined the best of the indirect and predictable parameters responding to a SV variation during SB. METHODS: Hemodynamic parameters, such as collapsibility of the inferior vena cava (cIVC), peak velocity variation in the common carotid artery (pvvCCA), collapsibility of the internal jugular vein (cIJV), and end-tidal carbon dioxide (ETCO₂) were measured 180 times (6 different positions each in 30 normal subjects). The variables changed with the SV at the upper body elevation of 60°and 30°, in the supine position, at the lower body elevation of 60°and 30°, and lumbar elevation. RESULTS: The SV showed the highest value at 30°of lower body elevation. Following fixed position changes, the ETCO₂ during SB was the factor most correlated with the SV when compared to cIVC, cIJV, and pvvCCA (β coefficient, 2.432 vs. −0.41, −0.033, and −0.654; P=0.004). The adjusted ETCO₂ showed a significant change with the SV, even though the change in ETCO₂ was not large. CONCLUSION: ETCO₂ was less influenced by the SB than cIVC, pvvCCA, and cIJV because the ETCO₂ change was in accordance but the variations of the other blood vessels did not coincide with a SV change. Therefore, ETCO₂ monitoring for predicting the SV would be more important than the variations in the vessels during SB.

Almost all colorectal carcinomas have been thought to develop from pre-existing adenomas. However, some colorectal carcinomas can arise directly from normal flat mucosa, and usually form infiltrative mass at the early stage. The carcinogenesis of this infiltrative carcinoma may be different from the well-known adenoma-carcinoma sequence, which usually forms a polypoid mass. The purpose of this study is to investigate the different expression of various oncogenes in polypoid carcinoma and infiltrative carcinoma. We performed immunohistochemical staining on p53, bcl-2, c-erbB-2 and MIB-1 in 29 polypoid carcinomas arised from adenomas, and 21 infiltrative carcinomas. The average tumor size of infiltrative carcinomas (5.5 cm) was larger than that of polypoid carcinomas (3.1 cm), and the polypoid carcinomas were differentiated more than the infiltrative carcinomas. The results of p53, bcl-2, c-erbB-2, and MIB-1 antisera immunoreactivity in the polypoid carcinoma were 79%, 17%, 21%, and 100%, and those in the infiltrative carcinoma were 71%, 29%, 29%, and 100%, respectively. However the diffuse positivities of p53 and MIB-1 antisera were slightly higher in the infiltraive carcinomas (62%, 76%) than in the polypoid carcinomas (55%, 41%) (p=0.63, 0.01). And the results of p53 and c-erbB-2 immunoreactivity in the adenomas were 52% and 17%, respectively, which is significantly lower than that in the polypoid carcinoma(p=0.03, 0.74). The immunoreactivty of bcl-2 in the adenoma was 72%, which was significantly higher than that in the polypoid carcinoma (17%) (p<0.01). In summary, we did not show the significant difference in expression of p53, bcl-2, c-erbB-2, and MIB-1 proteins between polypoid and infiltrative carcinomas. However, the tendency of infiltrative carcinomas having a more aggressive nature suggests another carcinogenetic mechanism is involved in the colorectal carcinogenesis.

This paper discusses the future development of air ambulance operations in Korea. Helicopter emergency medical services are a useful means of transporting critically ill patients to the right hospital, at the right time. It is an important element of the emergency medical system to treat acute diseases at the scene, or in transit. For more efficient operations of the emergency medical helicopters (air ambulances or the so-called ‘Doctor Helgi’ in Korea), various challenges are faced. These include, the expansion of air ambulance bases, proper placement of rendezvous points (landing point), increase of field transport requests, and the operation of night missions. First, it is necessary to reduce the disparity in the benefits of emergency medical care for critically ill patients through the expansion of helicopter bases. Second, through the advancement of joint operations of the pan-ministerial emergency medical helicopters, the time from dispatch to helicopter take-off should be minimized, and a quality improvement program for air transportation should be carried out. Third, it is necessary to increase the number of insufficient rendezvous points and ensure the safety of the helicopters during takeoff and landing, to activate field transportation. Finally, the safety of patients and medical staff should be secured through the systematic preparation of the air transport system for future night missions. To solve these tasks, an appropriate legal system for helicopter emergency medical service is required. Based on the improved system, it is expected that everyone will enjoy equal rights for health, regardless of the regions.

Medial meniscal root tears have been repaired using various methods. Arthroscopic all-inside repair using a suture anchor is one of the popular methods. However, insertion of the suture anchor into the proper position at the posterior root of the medial meniscus is technically difficult. Some methods have been reported to facilitate suture anchor insertion through a high posteromedial portal, a posterior trans-septal portal, or a medial quadriceptal portal. Nevertheless, many surgeons still have difficulty during anchor insertion. We introduce a technical tip for easy suture anchor insertion using a 25° curved guide and a soft suture anchor through a routine posteromedial portal.

Pneumothorax was recognized as a potential hazard of mechanical ventilation shortly after the introduction of the technique of tracheal intubation in the 19th century. Because the gases used in anesthesia are delivered from cylinders and wall outlets at higher than atmoshperic pressure, the possibility of damage to the lung is ever present. Immediate, prompt and adequate management of bilateral tension Pneumothorax are essentil, otherwise the patient dies rapidly. We had a case of bilateral tension Pneumothorax in a 3 year-old boy who underwent a B-E amputation of a severely crushed hand. We report this case along with a review of the literature on Pneumothorax.

PURPOSE: There are few reports describing objective and subjective outcomes in aged patients undergoing distal urethral polypropylene sling (DUPS) and canal transobturator tape (canal TOT) placement, which make the submucosal mesh 'tension-free' state in the operating room. We evaluated surgical outcomes and subjective satisfaction in patients over 70 years of age who underwent DUPS and canal TOT for the treatment of stress urinary incontinence (SUI). MATERIALS AND METHODS: We studied 29 consecutive patients over 70 years of age who underwent DUPS and canal TOT for genuine SUI between January 2006 and April 2008. Surgical outcomes were determined on the basis of hemoglobin change, operative time, hospital stay, and complications. Subjective satisfaction was determined on the basis of disease-specific quality of life, measured via the Incontinence Impact Questionnaire-short form (IIQ-7) and the Urogenital Distress Inventory-short form (UDI-6). RESULTS: No intraoperative or major postoperative complications were reported. No concomitant procedures were performed, including cystocele repair (n=0) or rectocele repair (n=0). The mean IIQ-7 and UDI-6 scores both decreased significantly after DUPS and canal TOT. Moreover, 82% of patients reported no SUI symptoms under any circumstances, and 91% of patients reported being rarely or never bothered by SUI symptoms. CONCLUSIONS: The surgical outcomes and subjective satisfaction seen with DUPS and canal TOT in this study were superior to those seen in other studies. However, it is possible that this study overestimated the effects of DUPS and canal TOT in aged women because of the small study sample. Therefore, additional studies are needed.

This article evaluates the overall current disease burden of North Korea through the recent databases of international organizations. It is notable that North Korea as a nation is exhibiting a relatively low burden from deaths and that there is greater burden from deaths caused by non-communicable diseases than from those caused by communicable diseases and malnutrition. However, the absolute magnitude of problems from communicable diseases like TB and from child malnutrition, which will increase the disease burden in the future, remains great. North Korea, which needs to handle both communicable and nutritional conditions, and non-communicable diseases, whose burden is ever more increasing in the nation, can now be understood as a country with the 'double-burden' of disease.

BACKGROUND: Vitamin C has critical features relavant to postoperative pain management and functional improvement; however, no study has yet evaluated the effectiveness of vitamin C on improving the surgical outcomes for spine pathologies. Thus, this study aimed to explore the impact of vitamin C on postoperative outcomes after single-level posterior lumbar interbody fusion (PLIF) for lumbar spinal stenosis in prospectively randomized design. We conducted a 1-year prospective, randomized, placebo-controlled, double-blind study to evaluate the impact of vitamin C on the postoperative outcomes after PLIF surgery. METHODS: A total of 123 eligible patients were randomly assigned to either group A (62 patients with vitamin C) or group B (61 patients with placebo). Patient follow-up was continued for at least 1 year after surgery. The primary outcome measure was pain intensity in the lower back using a visual analogue scale. The secondary outcome measures were: (1) the clinical outcome assessed using the Oswestry Disability Index (ODI); (2) the fusion rate assessed using dynamic radiographs and computed tomography scans; and (3) complications. RESULTS: Pain intensity in the lower back was significantly improved in both groups compared with preoperative pain intensity, but no significant difference was observed between the 2 groups over the follow-up period. The ODI score of group A at the third postoperative month was significantly higher than the score of group B. After the sixth postoperative month, the ODI score of group A was slightly higher than the score of group B; however, this difference was not significant. The fusion rates at 1 year after surgery and the complication rates were not significantly different between the 2 groups. CONCLUSIONS: Postoperative pain intensity, the primary outcome measure, was not significantly different at 1 year after surgery between the 2 groups. However, vitamin C may be associated with improving functional status after PLIF surgery, especially during the first 3 postoperative months.
