In the mandibular posterior molar area, ridge deficiency is an unfortunate obstacle in the field of implant dentistry. Many techniques are available to rebuild the deficient ridge. Selection and necessity of these techniques are associated with significant morbidity and often require a second surgical site. With the advent of guided bone regeneration (GBR), one may now graft the deficient ridge with decreased morbidity and without a second surgical site. In this case, guided bone regeneration procedures were performed with a combination of allograft, xenograft, and alloplast, excepting autogerous bone at severe defected mandibular alveolar ridge and then placed to the implant successfully. We report that implant placement were good in two cases.

기존의 폐암 발생의 고위험군(나이. 흡연력, $FEV_1$, 가족력, 직업적 발암물질의 노출력, 기존의 폐암 및 두경부 종양)에 대한 저선량 나선식 CT와 기관지 내시경 검사로 선별 검사 시 폐암의 유병률은 높아야 2%내외이고 대부분 그보다 낮은 것으로 알려져 있다. 특이도는 49-90%, 양성예측률은 10%이하로 선별검사 시 불필요한 검사를 초래하고 그에 따른 이환률과 사망률을 증가시키며 비용적인 문제를 야기하는 것으로 알려져 있다. 이에 기존의 고위험군에 대해 대상 환자를 더욱 더 좁힐 필요가 있으며, 이는 실제 임상적으로 이용 가능한 생물학적 표지자의 개발의 필요성이 있다고 하겠다. 그러나 현재까지 알려진 폐암조기검진에 대한 각종 진단 수기 중애서 상기의 3가지 방법(저선량 MDCT, 자가형광기관지경 및 객담내 MAGE)을 한꺼번에 시행하는 program은 비용적인 문제는 있지만 시도해 볼 만한 방법이라고 생각된다.

Extrarenal manifestations of hemolytic uremic syndrome (HUS) have increasingly been recognized and may be major determinants of mortality and morbidity. Although microthrombi are often found in the pulmonary and coronary circulation, apparent lung and cardiac involvement are clinically infrequent. We describe here a 10-month-old boy with HUS who developed pulmonary hemorrhage, acute respiratory distress syndrome and dilated cardiomyopathy. Complete renal as well as clinical recovery from these very uncommon complications was achieved by optimum supportive care.

Equine colic is a major concern in equine industry due to high morbidity and mortality rates. The purpose of this study was to establish mortality rates during medically and surgically treated colic and to identify potential prognostic indicators for mortality of equine colic in Korea. The overall mortality rate was 18/119 (15%). The 93 cases (78%) were treated medically and 26 cases (22%) surgically out of the 119 records reviewed. The mortality rate in small intestinal lesion was 7/9 (78%) and strangulating lesion was 10/11 (91%). The significance between individual factors and prognosis of equine colic was not valid but high frequency rate was found in ${\leq}3$ years age (59%) and male (50%). In dead group showed higher, rectal temperature and heart rate than those of survived group. The mortality rate was significantly high in the pale mucous membrane color and severe pain and decreased intestinal motility. In laboratory factors, dead group showed lower level of platelet than survived group, and had higher values of RBC, hemoglobin, PCV with significance (P < 0.05). Group with increased enzyme activity of CK, LDH, glucose showed poor prognosis.

The Hamstring autograft and the bone patellar bone tendon autograft have been widely used for anterior cruciate ligament reconstruction. In recent years, use of hamstring autograft for ACL reconstrution has been increased. The reason seems to be the advantages of the hamstring tendon such as high ultimate tensile load, low donor site morbidity and development of graft fixation method. These theoretical advantages have been increased as studies have shown that hamstring tendons actually regenerate after harvesting for ACL reconstruction. However, the concerns have arisen regarding the disadvantages of hamstring harvest, which were weakness of tibial internal rotation, the loss of flexion strength. The flexion strength loss has been controversial, therefore it needs to study whether restoration of flexion strength after hamstring regeneration is or not. In this study, we reviewed the current research of concerns on the advantage and disadvantage of hamstring tendon autograft and the hamstring regeneration. Furthermore, we compared the earlier studies and experiences regarding Hamstring regeneration with our research.

Partial thickness rotator cuff tears (PTRCTs) are now a well-established clinical entity, yrt there is no consensus in regards to surgical management. Recommended treatment varies widely from simple debridement of the torn tendon to subacromial decompression to excision of the degenerative tendon and repair. Surgery may be performed using an open, arthroscopically assisted (miniopen), or entirely arthroscopic procedure. The advantages and disadvantages of open and arthroscopic procedures may lie in the balance between precision and morbidity. Visualization of both the articular and bursal surfaces is mandatory to determine the level of rotator cuff disease and formulate a treatment strategy. Because these tear often are secondary finding, recognition of the primary pathology is critical. Treatment of the primary problem usually remedies the partial tear. However, when there is significant PTRCT, an arthroscopic or open repair of the diseased tendon will give the most consistent results.

Mortality and morbidity of malignant hyperthermia has decreased markedly by the avoidance of succinylcholine, and the earlier detection and introduction of dantrolene. We report a fourteen-year-old boy who developed malignant hyperthermia during general anesthesia. He showed the earlier clinical signs, such as elevation of end-tidal $CO_2$, tachycardia, and hypertension. After prompt administration of dantrolene, operation was continued with profopol and midazolam. Rhabdomyolysis and myoglobinuria followed, and were managed by hydration and alkalinization of urine. Azotemia did not occur, and he was discharged without any sequelae on the $10^{th}$ postoperative day.

Purpose: The advantages of air reduction are the ease of performing the procedure, reduced radiation time and lower morbidity rate if perforation occurs. But, patients who fail air reduction undergo a laparotomy at which 10% have spontaneously reduced. The first enema decreases the edema and venous congestion of bowel wall, thus repeated reduction may succeed. The aim of this study is to evaluate the efficacy of delayed repeated pneumatic reduction of intussusception in patients with failure of an initial attempt. Methods: Between January 1998 and December 1999, 21 patients with proven intussusception received repeated delayed reduction 1 to 3 hours following the first failed attempt. These patients were in stable condition and did not have peritonitis, shock or toxic sign. Results: Before reduction, the patients had symptoms and signs for 6 to 48 hours (median 24 hr). The interval from the first reduction to the repeated was 1 to 3 hours (median 2.2 hr). The success rate of repeated reductions was 76.2% (16 of 21 patients), and 23.8% (5 of 21 patients) required surgery. Four of 5 patients requiring surgery were manually reduced and 1 spontaneously reduced in the operating room. Conclusion: We recommended a repeated reduction in patients with intussusception who are in stable clinical condition after an unsuccessful initial reduction attempt.

Toxic gases and soot deposition as a consequence of smoke inhalation can cause direct injury to the upper and lower airways and even to the lung parenchyma. A delay in proper and prompt therapy can be detrimental to critically ill burn patients with an inhalation injury. Therefore, serial chest radiography is an important diagnostic tool for pulmonary complications during treatment. The radiographic findings of the chest include normal, consolidation, interstitial and alveolar infiltrates, peribronchial thickening, atelectasis, cardiogenic and non-cardiogenic pulmonary edema, and a pneumothorax as acute complications of smoke inhalation. In addition, bronchiectasis, bronchiolitis obliterans and pulmonary fibrosis can occur as late complications. We encountered a case of 44-year-old male who presented with acute lung injury after an inhalation injury. He required endotracheal intubation and mechanical ventilation due to respiratory failure. He was managed successfully with conservative treatment. Later, a cavitary lesion of the left upper lobe was observed on the chest radiography and computed tomography, which was complicated by massive hemoptysis during the follow-up. However, the cavitary lesion disappeared spontaneously without any clinical consequences.
