Purpose: To evaluate the drainage effect of silk suture following aspiration of the bursa as an early treatment of chronic lateral malleolar bursitis. Materials and Methods: Thirteen cases, which have over two weeks of history and over one year of follow-up, were investigated. The average duration of follow-up was 16.4 months. The average symptom duration before introduction into this study was 7.8 weeks. With an aseptic technique, the aspiration of the bursa was done with 18G needle and syringe and then the insertion of silk suture through the aspiration needle was performed. The amount of drainage was identified two or three times in a week and stitch out was done at the cessation of drainage. Over one year follow-up, recurrence, infection, pain, and limitation of range of motion were investigated by telephone interview. Results: Redness around the insertion site of silk suture was found in all cases, but there was no development of active infection or recurrence. The average duration of treatment is 10.4 days. Conclusion: The drainage with silk suture following aspiration of the bursa is less invasive and very effective method in the early treatment of chronic lateral malleolar bursitis.

Objective : To evaluate the role of lumbar drainage in the prevention of shunt-dependent hydrocephalus after treatment of ruptured intracranial aneurysms by coil embolization in good-grade patients. Methods : One-hundred-thirty consecutive patients with aneurysmal subarachnoid hemorrhage in good-grade patients (Hunt & Hess grades I-III), who were treated by coil embolization between August 2004 and April 2010 were retrospectively evaluated. Poor-grade patients (Hunt & Hess grades IV and V), a history of head trauma preceding the development of headache, negative angiograms, primary subarachnoid hemorrhage (SAH), and loss to follow-up were excluded from the study. We assessed the effects on lumbar drainage on the risk of shunt-dependent hydrocephalus related to coil embolization in patients with ruptured intracranial aneurysms. Results : One-hundred-twenty-six patients (96.9%) did not develop shunt-dependent hydrocephalus. The 2 patients (1.5%) who developed acute hydrocephalus treated with temporary external ventricular drainage did not require permanent shunt diversion. Overall, 4 patients (3.1%) required permanent shunt diversion; acute hydrocephalus developed in 2 patients (50%). There was no morbidity or mortality amongst the patients who underwent a permanent shunt procedure. Conclusion : Coil embolization of ruptured intracranial aneurysms may be associated with a lower risk for developing shunt-dependent hydrocephalus, possibly by active management of lumbar drainage, which may reflect less damage for cisternal anatomy than surgical clipping. Coil embolization might have an effect the long-term outcome and decision-making for ruptured intracranial aneurysms.

Background: We analyzed our experience with descending necrotizing mediastinitis (DNM) treatment and investigated the efficacy of video-assisted thoracoscopic surgery (VATS) for mediastinal drainage. Methods: This retrospective analysis included patients who underwent surgical drainage for DNM at our hospital from 2005 to 2020. We analyzed patients' baseline characteristics, surgical data, and perioperative outcomes and compared them according to the mediastinal drainage approach among patients with type II DNM. Results: Twenty-five patients (male-to-female ratio, 18:7) with a mean age of 54.0±12.9 years were enrolled in this study. The most common infection sources were pharyngeal infections (60%). Most patients had significantly increased white blood cell counts, elevated C-reactive protein levels, and decreased albumin levels on admission. The most common DNM type was type IIB (n=16, 64%), while 5 and 4 patients had types I and IIA, respectively. For mediastinal drainage, the transcervical approach was used in 15 patients and the transthoracic approach (VATS) in 10 patients. The mean length of hospital stay was 26.5±23.8 days, and the postoperative morbidity and in-hospital mortality rates were 24% and 12%, respectively. No statistically significant differences were found among patients with type II DNM between the transcervical and VATS groups. However, the VATS group showed shorter mean antibiotic therapy duration, drainage duration, and hospital stay length than the transcervical group. Conclusion: DNM manifested as severe infection requiring long-term inpatient treatment, with a mortality rate of 12%. Thus, active treatment with a multidisciplinary approach is crucial, and mediastinal drainage using VATS is considered relatively safe and effective.

Excessive oral and maxillofacial bleeding causes upper airway obstruction, bronchotracheal and gastric aspiration and hypovolemic shock. Therefore, the rapid and correct bleeding control is very important for saving lives in the emergency room. Despite the conventional bleeding control methods of wiring (jaw fracture, wound suture and direct pressure), continuous bleeding can occur due to the presence of various bleeding disorders. There are five main causes for excessive bleeding disorders in the clinical phase; (1) vascular wall alteration (infection, scurvy etc.), (2) disorders of platelet function (3) thrombocytopenic purpura (4) inherited disorders of coagulation, and (5) acquired disorders of coagulation (liver disease, anticoagulant drug etc.). In particular, infections can alter the structure and function of the vascular wall to a point at which the patient may have a clinical bleeding problem due to vessel engorgement and erosion. Wound infection is a frequent cause of postoperative active bleeding. To prevent postoperative bleeding, early infection control using a wound suture with proper drainage establishment is very important, particularly in the active bleeding sites in a contaminated emergency room. This is a case report of a rational bleeding control method by rapid wiring, wound suture with drainage of a rubber strip & iodoform gauze and wet gauze packing, in a 26-year-old male cerebral palsy patient with active oral and maxillofacial bleeding injuries caused by a traffic accident.

This is a retrospective study on emergency patients with active oral bleeding. The study was based on a series of 135 patients treated as emergency patients at Wonju Christian Hospital, from Jan. 1, 1997, to Dec. 31, 2001. The postoperative bleeding was the most frequent cause of active oral bleeding in emergency room and bleeding from trauma and medically compromised (bleeding disorders) patients were next in order of frequency. In the injury of maxillofacial vessels, peak incidence was occurred in the inferior alveolar vessel (42.9%), followed by the submucosal vessel of lip & cheek, the superior alveolar vessel, and sublingual vessels. The most common disease of bleeding disorders was vascular wall alteration (infection, etc), followed by liver disease, thrombocytopenic purpura, anti-coagulation drugs in order. In the characteristics of dental diseases on bleeding disorders, periodontal disease and alveolar osteitis (osteomyelitis) were more common. The hemostasis was most obtained by use of wound suture, simple pressure dressing, drainage for infection control and primary interdental wiring of fracture. In the complication group, the infrequent incidence was showed in vomiting, hypovolemic shock, syncope, recurred bleeding & aspiration pneumonia. In the uncontrolled oral bleeding, the injured vessels were suspected as skull base & ethmoidal vessels. In this study, authors found that the close cooperation between the dentistry (Oral and maxillofacial surgery) and the medicine (emergency & internal medicine) was the most important for early proper control of active oral bleeding. And then post-operative wound closure, drainage for infection control and previous systemic evaluation of bleeding disorders were critical for the prevention of postoperative bleeding in the local dental clinic.

산성광산배수 처리방법은 적극적 처리방식과 소극적 처리방식이 일반적으로 사용되고 있으며, 이때 발생되는 부산물인 슬러지는 국내에서 약 5천 톤/년으로 발생하고 있다. 본 연구는 적극적 처리방식 중 물리·화학적 처리방식으로 정화 후 발생되는 슬러지의 특성을 조사하여 재활용 가능여부를 검토하기 위함이다. 5개소(D, H, S, T, Y) 수질정화시설의 슬러지의 특성을 물리·화학적 분석을 통해 검토하였다. 그 결과 pH는 pH 5.86 ~ pH 7.89로 측정되었고, 수분함량은 51 % ~ 82 %로 분석되었으며, 입자크기는 대부분 25 ㎛보다 작은 미립자로 구성되었음을 확인할 수 있었다. ICP-OES를 이용한 슬러지 내 무기물질 분석결과, Al, Fe, Mn의 농도범위는 각각 1,189 mg/kg ~ 129,344 mg/kg, 106,132 mg/kg ~ 338,011 mg/kg, 3,472 mg/kg ~ 11,743 mg/kg로 조사되어 고농도로 존재함을 확인 할 수 있었다. 그 외 무기물질 중 중금속류에 대해서는 T-슬러지는 As와 Zn, D-슬러지는 Cd, H-슬러지는 Ni, S-슬러지는 Zn, Y-슬러지는 Cd의 농도가 토양오염우려기준을 초과하였다. 또한 슬러지의 용출 특성을 알기위해 폐기물 용출시험(KSLT) 및 TCLP 시험을 진행하였다. 슬러지 재활용시 용출되어 지하수에 미치는 영향 확인을 위해 지하수 수질기준(생활용수) 20개 항목에 대하여 수행하였다. 용출시험결과 특정유해물질 16개 항목에서 모두 불검출로 확인되었으며, 일반항목 4개 항목에 대해서는 모두 생활용수 기준치 이내로 만족하였다. XRD, SEM-EDS의 분석결과, 슬러지는 주로 방해석, 석영의 패턴을 보였으며, 높은 Fe, O의구성비율로철수산화물이높은비중을차지하는것으로보였다. 이를 통해서 비매체접촉형 방식의 재활용의 가능성이 있을 것으로 판단된다.

A clinical investigation was reported on 17 cases of spontaneous pneumothorax requiring surgical mana-gement. Males outnumbered females 15:2. Determination of the etiology in this series showed that the majority were pulmonary tuberculosis and paragonimiasis. Several others had pneumonia, lung abscess, cyst and blebs. It is of particular interest that the acute inflammation of respiratory system was younger age group, pulmonary tuberculosis & paragonimiasis were between 2 nd and 3 rd decades, and lung abscess, cyst, blebs were above 4 th decade. Pulmonary tuberculosis was far advanced bilateral and active. The ratio of right to left side was 13:6 and both side involved in 2 cases. In about half cases of patients, above 50%-collapsed lung associated with mediastinal shifting developed. The complications were pleural effusion and bronchopleural fistula. The former was 13 cases [76.4%] in which 3 cases combined with mixed infection, and latter was 5 cases. As the management, 11 cases were subjected to intercostal or rib resection drainage with continuous suc-tion. Among 11 drainage cases, 8 cases were successful in acute stage and 3 cases failed in chronic stage. This faiure was due to interference with re-expansion of collapsed lung for peel formation and broncho-pleural fistula. The open thoractomy was applied in 9 cases, among which primary operation were 5 cases and drainage failure were 4 cases. Among 11 cases subjected to the open thoracotomy, wedged resection was performed in 3 cases including paragonimiatic cyst, and pneumonectomy in 1 case-tuberculosis, and decortication only was performed in 2 cases in paragonimiasis. Decortication & lung resection was carried out in 2 patients among which ruptured lung abscess 1 case and ruptured multiple blebs 1 case. There was no case of death but prognosis of the tuberculosis may be poor because of far advanced bilateral and active pulmonary tuberculosis.

추가령 열곡에서 열하분출에 의한 용암대지가 형성되면서 기존의 하곡들이 매몰되어 하계망 혼란이 일어나고, 새로운 분수계가 형성과 함께 하계망 재편성이 진행되고 있다. 이 지역은 안변 남대천, 북한강, 임진강, 한탄강 유역이 접하는 복잡한 분수계 혼란 지역으로서 분수계의 핵심 지점은 중심분출 화산인 평강의 오리산(453m)과 680봉이며, 보다 평탄한 곳에서는 하천 쟁탈이 복잡하게 전개되고, 평탄면에서 유역이 가까이 접하면서 쟁탈 전선도 형성된다. 특히 오리산은 4개의 분수계를 가르는 분수점 기능을 한다. 고도가 높은 산록에서는 두부 침식에 의해 하천 쟁탈이 발생한다. 수문지형적으로는 용암이 하곡을 메우면서 범람원의 면적이 줄어들어 호우에 의한 침수 가능성이 높아지게 되며, 보다 활발한 용암대지 개석작용을 유발하는 것으로 판단된다.
