  • Background/Aims: Gastrointestinal bleeding is a significant and potentially lethal event. We aimed to review the efficiency and safety of self-assembling peptides for the treatment and prevention of gastrointestinal tract bleeding. Methods: We conducted a systematic search for studies describing the endoscopic use of self-assembling peptides for treatment or prevention of bleeding in the gastrointestinal tract in a parallel, independent fashion. The primary outcomes were rates of successful initial hemostasis, delayed bleeding, and rebleeding. The secondary outcomes were adverse events and ease and volume of gel used. Results: Seventeen studies were analyzed. Overall success rate of self-assembling peptides in gastrointestinal bleeding was 87.7% (38%-100%), regardless of etiology or associated treatments. Rebleeding rate ranged from 0% to 16.2%, with a mean of 4.7%, and overall delayed bleeding rate was 5% (range, 0%-15.9%). Only three adverse events were reported in a pooled number of 815 patients. The volume of gel used varied (0.43 to 3.7 mL) according to indication and type of bleeding. Conclusions: The limited available data on the use of self-assembling peptides in gastrointestinal endoscopy suggest a high efficiency and good safety profile.

  • Objective: To investigate the relationship between the efficacy and safety of different doses of thalidomide (Thal) plus dexamethasone (Dex) as the initial therapy in elderly patients with newly diagnosed multiple myeloma (MM). Methods: Clinical data of 28 elderly patients with newly diagnosed MM who underwent the TD regimen as the initial therapy were analyzed retrospectively. The patients were divided into two groups according to the maximal sustained dose of Thal: lower dose (group A) and higher dose (group B). The overall response rate (ORR), progression free survival (PFS), overall survival (OS), and adverse events (AES) were compared between the two groups. Results: A total of 28 patients were followed up with a median of 18 months. The ORR was 60.1%. The median response time and PFS were 2.0 and 17.0 months, respectively. The mean sustained dose of Thal in group B was significantly higher than group A (292.9 mg v 180.4 mg, P=0.01). There was no significantly difference in ORR (57.1% v 64.3%, P=1.00) and PFS (9.63months v 17.66 months, P=0.73) between groups A and B. During the follow up, only five patients died (<40%) and, therefore, median OS values were not available. It is estimated, however, that the mean survival time in the two groups was 35.6 and 33.4 months (P>0.05), respectively. All of the patients tolerated the treatment well. The incidence of AES in patients with a grading above 3 in group B was significantly higher than in group A (P=0.033). Conclusions: The TD regimen results in a high response rate and manageable AES as the initial therapy in elderly patients with MM. TD should be considered as the front line regimen for the treatment of elderly patients with MM in areas with financial constraints. The clinical response can be achieved at a low dose Thal with minimal toxicity.

  • Purpose : This study analyzes prehospital care report of emergency service at prehospital stage, examines characteristics of activities of 119 paramedics and its users and aims to provide help for improving emergency system in future. Methods : Data collected were 119 prehospital care report and hospital records with 7,160 patients to emergency room by 119 ambulance from Jan. 1 to Dec. 31, 2006 and percentage and frequency of the data were obtained. Results : 1) Use of emergency room by 119 ambulance was increased in summer and autumn such as August(9.1%), September(11.2%) and October(13.5%) and it was more frequently used on Monday(17.3%), Saturday(17.2%) and Friday(16.1%) by telephone(98.6%). 2) Using emergency room was most in over sixties(51.8%), men(64.2%), community residents (78.3%), by report of family(50.3%) and at '09:01~12:00'(16.5%). 3) Symptoms of emergency room users included headache, chest pain, stomachache, lumbago and others as 40.6% and places where patients were found were at home(60.1%) due to chronic internal diseases at 49.2%. 4) Most of non-emergency patients(80.2%) arriving at hospital had normal pupil condition (88.4%) and clear consciousness(71.2%) and most of them left hospital after having first-aid treatment. 5) Physiological symptom tests evaluated by paramedics at prehospital stage included blood pressure(56.6%), pulse(22.9%), breathing(13.0%) and temperature(9.2%), and there was no SPo2 case. 6) Classification of severity by paramedics showed difference as emergency patients(18.0%) by paramedics and those(24.9%) by hospital. 7) First-aid treatments by paramedics at prehospital stage were promoting comfort(28.9%), hemostasis(7.7%), fixing cervical vertebrae(4.0%) and ensuring vein route(3.1%). 8) Selectors of medical agency were patients or guardians(86.2%) and emergency medical technicians(73.6%). Conclusion : To sum up the above research, it was found that percentage of using 119 ambulance by non-emergency patients was higher and paramedics performed basic first-aid treatment rather than professional first-aid treatment due to several conditions such as legal problems, range of allowance, etc. Therefore, it is considered that method to reduce frequency of ambulance by non-emergency patients and approaches to alleviate limitations of allowance of paramdeics to make them perform effective first-aid treatment at prehospital stage should be sought in the dimension of individual, organization and government.

  • Objective : Fibrin sealants have been used for hemostasis, sealant for cerebrospinal fluid leakage, and adhesive barrier in neurosurgery. Further, as its clinical use and role of an effective drug delivery vehicle have been proposed. This study was performed to measure antibacterial activity and continuous local antibiotic release from different concentrations of vancomycin-impregnated fibrin sealant in vitro. Methods : Antibacterial activity was investigated by disk diffusion test by measuring the diameter of the growth inhibition zone of bacteria (methicillin-resistant Staphylococcus aureus, ATCC29213) from vancomycin-embedded fibrin sealant disc diluted at five different concentrations (C1-C5; 8.33, 4.167, 0.83, 0.083, and 0.0083 mg/disc, respectively). Continuous and conditioned release of vancomycin concentration (for 2 weeks and for 5 days, respectively) were also measured using high-performance liquid chromatography (HPLC) method. To mimic the physiologic wound conditions with in vitro, conditioned vancomycin release in phosphate buffer solution (PBS) was measured and replaced PBS for five consecutive days, half a day or completely daily. Results : In the disk diffusion test, the mean diameters of bacterial inhibition zone were 2.54±0.07 cm, 2.61±0.12 cm, and 2.13±0.15 cm (C1, C2, and C3 respectively) but 1.67±0.06 cm and 1.23±0.15 cm in C4 and C5, respectively. Continuous elution test elicited the peak release of vancomycin from the fibrin sealant at 48 hours, with continued release until 2 weeks. However, conditioned vancomycin release decreased to half or more on day 2, however, the sustainable release was measured over the therapeutic dose (10-20 ㎍/mL) for 5 days and 4 days in assays of half and total exchange of PBS. Conclusion : This study suggests that fibrin sealant can provide an efficient vehicle for antibiotic drug release in a wide range of neurosurgical procedures and the safe and effective therapeutic dose will be at the concentration embedded of 4.167 mg/disc or more of vancomycin.

  • The appropriate care to the dental emergency patients is much important in the aspect of community dental service. To attain such a purpose, the sacred duty of the training of oral and maxillofacial surgeons is required. So, a retrospective study on the characteristics of dental injuries and diseases in emergency care unit will be very meaningful. This study was carried by reviewing the charts and radiographic films of 3,394 patients, treated for dental emergency at Wonju Christian Hospital, Republic of Korea, from January 1, 1993 to December 31, 2002. All patients were classified to 6 groups including trauma, toothache, infection, hemorrhage, TMJ disorder and the others. The clinical characteristics of diseases and treatment modalities according to each group were analyzed. The trauma (73.9%) was the most frequent cause in dental emergency patients, and acute toothache, odontogenic infection, oral hemorrhage, and TMJ disorder were next in order. Gender prediction was male (68%), there were many patients on May and December in the monthly frequency, and the most frequent age group was from 0 to 9 years. In the trauma group, male (68.6%) was predominant, and soft tissue injuries and primary closures were the most frequent type of injury and treatment. In jaw fractures, traffic accidents were the most cause and the weakest site was mandibular symphysis area, and mandibular angle, condyle, and body area were next in order. In the acute toothache group, the cause was dental pulpitis mostly and treatment for that was drug administration mainly. Buccal space abscess in infection group had the largest incidence (24.5%), and common treatments were incision and drainage and medications. In the hemorrhage group, a major cause was postoperative bleeding (60.3%) and hemostasis was obtained by pressure dressing, curettage and suture. For the TMJ disorder group, the peak incidence (63.8%) was shown in the post-traumatic myofascial pain dysfunction syndrome and its primary care was medication such as analgesics and sedatives. In the other group, the various specific symptoms were complained due to acute sialadenitis, trigeminal neuralgia, acute stomatitis, chemical burn, terminal stage neuritis of head and neck cancer, and foreign body aspiration. In conclusion, for the rapid and proper care of the emergency dental diseases, well-trained education should be presented to the intern and resident course of oral and maxillofacial surgery. And it is demanded that oral and maxillofacial surgeons must be prepared in knowledge and skill for such emergency care.

  • 한방에서 지혈 및 어혈 제거용으로 사용되고 있는 눈개승마는, 최근 약용 산채로 그 수요가 급증하고 있다. 본 연구에서는 눈개승마의 항혈전 활성을 평가하고자 눈개승마 지상부로부터 에탄올 추출물 및 이의 순차적 유기용매 분획물을 조제하여 이들의 혈액응고 저해활성 및 혈소판 응집저해 활성을 평가하였다. 그 결과, 눈개승마의 에탄올 추출물(0.5 mg/ml)에서 1.4~2.3배의 우수한 TT, PT, aPTT 연장효과를 확인하였으며, 특히 내인성 혈액응고 인자 저해효과가 우수함을 확인하였다. 분획물에서는 ethylacetate 분획에서 가장 우수한 aPTT 연장효과를, butanol 분획에서는 혈액응고 촉진효과를 확인하였다. 혈소판 응집저해 활성평가의 경우, 눈개승마 에탄올 추출물은 임상에서 사용하는 항혈소판제인 아스피린에 필적하는 효과를 나타내었으며, 특히 butanol 분획은 0.25 mg/ml 농도에서 아스피린 0.5 mg/ml 에 해당하는 강력한 혈소판 응집저해능을 나타내었다. 상기의 에탄올 추출물과 활성 분획물들은 0.5 mg/ml 농도까지 인간 적혈구에 대한 용혈활성을 나타내지 않아, 눈개승마가 천연물 유래의 항혈전제로 개발 가능함을 확인하였으며, 특히 상기 활성분획들이 높은 함량의 total polyphenol, total flavonoid, total sugar를 포함함을 고려할 때, 활성물질의 정제시에는 더욱 강력한 항혈전 활성을 나타내리라 판단된다. 본 연구결과는 눈개승마의 항혈전 활성의 최초 보고이다.

  • Purpose: Despite recent developments in the management of trauma patients in South Korea, a standardized system and guideline for trauma treatment are absent. Methods: Five guidelines were assessed using the Appraisal of Guidelines for Research and Evaluation II instrument. Results: Restrictive volume replacement must be used for patients experiencing shock from trauma until hemostasis is achieved (1B). The target systolic pressure for fluid resuscitation should be 80-90 mmHg in hypovolemic shock patients (1C). For patients with head trauma, the target pressure for fluid resuscitation should be 100-110 mmHg (2C). Isotonic crystalloid fluid is recommended for initially treating traumatic hypovolemic shock patients (1A). Hypothermia should be prevented in patients with severe trauma, and if hypothermia occurs, the body temperature should be increased without delay (1B). Acidemia must be corrected with an appropriate means of treatment for hypovolemic trauma patients (1B). When a large amount of transfusion is required for trauma patients in hypovolemic shock, a massive transfusion protocol (MTP) should be used (1B). The decision to implement MTP should be made based on hemodynamic status and initial responses to fluid resuscitation, not only the patient's initial condition (1B). The ratio of plasma to red blood cell concentration should be at least 1:2 for trauma patients requiring massive transfusion (1B). When a trauma patient is in life-threatening hypovolemic shock, vasopressors can be administered in addition to fluids and blood products (1B). Early administration of tranexamic acid is recommended in trauma patients who are actively bleeding or at high risk of hemorrhage (1B). For hypovolemic patients with coagulopathy non-responsive to primary therapy, the use of fibrinogen concentrate, cryoprecipitate, or recombinant factor VIIa can be considered (2C). Conclusions: This research presents Korea's first clinical practice guideline for patients with traumatic shock. This guideline will be revised with updated research every 5 years.
