  • Purpose: The purpose of this study was to investigate differences between a pulmonary aspiration group and a non-pulmonary aspiration group in glucose concentration of tracheal secretions by measuring time and feeding methods. Method: The subjects were 36 ICU patients who were receiving formula via nasogastric tubes and had endotracheal tubes or tracheostomy tubes. Tracheal secretions were collected by connecting suction traps to a suction catheter in three different times(within 1 hour after feeding, between 1 to 2 hours after feeding, and between 2 to 3 hours after feeding) for 2 days, overall six times. Glucose concentration of tracheal secretions was measured with the glucometer(Accucheck II). Results: Glucose concentration of tracheal secretions increased in progression after feeding. The mean of specimens collected last(between two to three hours after feeding) was shown to be the highest value(M=61.61mg/dl) in the pulmonary aspiration group. Significantly(p=.000) more subjects(94.44%) in the pulmonary aspiration group received formula via a 50cc syringe than those in the non-pulmonary aspiration group(22.22%). Conclusion: Critically ill patients may need more time for head-elevation after tube feeding to prevent pulmonary aspiration. In practice, enteral formula should not be given the patients via a $50_cc$ syringe anymore, instead a feeding bag or infusion pump should be used to prevent pulmonary aspiration.

  • Carcinsarcoma is an uncommon pulmonary malignancy characterized by carcinmatous parenchyma and sarcomatous stroma. The cytologic, immunohistochemical and ultrastructural features of a case of pulmonary carcinosarcoma suspected by fine needle aspiration cytology is presented. Only bizarre spindle cells arranged in loose groups, in microtissue fragments and in a dissociate fashion were present on the aspiration smears. They were markedly positive for vimentin. The epithelial component was not found, which was probably due to marked paucity of carcinomatous component that was proved by histologic examination of the resected tumor. The diagnosis of pulmonary carcinosarcoma should be conidered whenever poorly differentiated epithelial ceil groups with a malignant mesenchymal component set in a myxoid background are seen in a pulmonary cytology specimen.

  • Chemical pneumonitis induced by hydrocarbon aspiration is rare in Korea. Kerosene is a petroleum distillate with low viscosity and high volatility. We report two adult cases of chemical pneumonitis caused by the accidental aspiration of kerosene. They were treated successfully with antibiotics and systemic corticosteroids, and recovered without complications.

  • We report a case of pulmonary aspiration during induction of general anesthesia in a patient who was status post esophagectomy. Sudden, unexpected aspiration occurred even though the patient had fasted adequately (over 13 hours) and received rapid sequence anesthesia induction. Since during esophagectomy, the lower esophageal sphincter is excised, stomach vagal innervation is lost, and the stomach is flaccid, draining only by gravity, the patient becomes vulnerable to aspiration. As the incidence of perioperative pulmonary aspiration is relatively low, precautions to prevent aspiration tend to be overlooked. We present a video clip showing pulmonary aspiration and discuss the literature concerning the risk of aspiration and its preventive strategies.

  • Purpose: This study was performed to test the clinical usefulness of the glucose test strip method for early detection of pulmonary aspiration in tube fed patients. Method: The subjects for the study were 36 patients who were receiving enteral feedings and 39 patients who were not given enteral feedings. For the analysis, the tube fed patients were divided into two groups (clinically significant aspiration and no aspiration) according to criteria. Result: The mean glucose concentration of tracheal secretions from non enteral fed patients was 26.35mg/dl and were lower than those concentrations found in tube fed patients (32.75mg/dl). The mean glucose concentration of the aspiration group was 45.60mg/dl and the glucose concentration of the non aspiration group was 19.93mg/dl. The difference was statistically significant (t=2.163, p=.038). More subjects in the no aspiration group ($73\%$) than the aspiration group ($56\%$) had glucose concentrations below 20mg/dl. After deleting the cases that had samples containing blood, glucose concentrations of tracheal aspirates were lower in both groups. Conclusion: The glucose level of the aspiration group was significantly lower than the no aspiration group and more subjects in the aspiration group had a glucose level higher than 101mg/dl. Therefore, the glucose test of tracheal secretions in tube fed patients could be a desirable test for screening for tracheal aspiration. Especially the patient who is showing repeatedly high glucose levels should not be given feedings until reassessment is completed.

  • Pulmonary amyloid deposition generally occurs with concurrent primary systemic amyloidosis. Localized forms of pulmonary amyloidosis are rare and appear most frequently as an incidental finding on chest radiographs. We present a case of nodular pulmonary amyloid tumor suggested by fine needle aspiration cytology(FNAC) and confirmed by histology examination with the polarizing light microscopy. A 41-year-old woman presented with ill-defined nodules. In the middle and lower lobes of both lungs. FNAC of the nodules revealed waxy, acellular amorphous fragments. Thoracotomy for diagnosis may be avoided by FNAC diagnosis of this unusual lesion.

  • Pulmonary hamartoma is the most common benign tumor of the lung but rarely encountered in routine cytologic work-up. We recentely experienced a case of fine needle aspiration cytology of pulmonary hamartoma in a 65-year old male patient. The characteristic cytopathologic features were 1) The mesenchymal components with cuboidal epithelial cells in a clean background, 2) The presence of fibromyxoid mesenchymal component composed of fibroblasts in a loose fibrillary stroma, and 3) Antler-liker fibromyxoid cluster having the rimming of epithelial cells which correspond to the epithelial glowing in cleft-like fashion in pulmonary hamartoma.

  • Pulmonary hamartomas are uncommon benign tumors, usually discovered radiologically as a solitary coin lesion in asymptomatic individual. The approach to the patient with a peripheral lung nodule has changed with the increasing acceptance of fine needle aspiration cytology(FNAC) as a rapid, safe, inexpensive, and highly accurate diagnostic tool. However, a few reports describing the FNAC findings of pulmonary hamarioma have appeared in the cytologic literature and the experience of FNAC is limited. We reviewed all 9 cases of pulmonary hamartoma with histologic confirmation after FNAC seen at Asan Medical Center since 1995 to evaluate cytologic findings and to determine the value of FNAC in identifying that lesion. Originally, seven of nine patients were diagnosed as pulmonary hamartoma, while two patients were diagnosed as inflammatory lesion and adenocarcinoma of each. On review, eight of nine patients were considered as diagnostic of pulmonary hamartoma. The diagnostic findings in FNAC of pulmonary hamartoma were the presence of fibrillary myxoid tissue with spindle cells as well as hyaline cartilage.

  • Thoracoscopic needle aspiration is a good alternative for a centrally-located solitary pulmonary nodule (SPN) suspected of being lung cancer without severe pleural adhesion. The authors report the technique of thoracoscopic needle aspiration biopsy in a SPN just in the medial aspect of the truncus anterior pulmonary artery and the right upper lobe bronchus.

  • 목 적: 영유아에서 위식도 역류는 흔한 질환이며, 위식도 역류의 합병증으로 위 내용물의 폐 흡인에 의한 만성 호흡기 질환이 생길 수 있으나 이를 진단하기 위한 표준적인 검사 방법이 없다. 본 연구에서는 위식도 역류와 폐 흡인 진단 방법으로서 위식도 역류 신티그래피의 유용성을 평가하고자 하였다. 방 법: 위식도 역류로 인한 흡인 폐렴이 의심된 35명의 환아와 정상 대조군 5명을 대상으로 하였다. 모든 대상아에게 $^{99m}Tc$-tin colloid를 첨가한 우유를 수유한 후 위식도 역류 신티그래피를 시행하였다. 위식도 역류를 진단하기 위해 1시간 동안 동적 영상을 촬영하였고, 폐 흡인을 진단하기 위해 6시간과 24시간 후 지연 영상으로 정적 영상을 얻었다. 폐 흡인의 진단을 위해 육안분석과 함께 양쪽 폐에 관심 영역을 설정하여 정량 분석을 시행하였다. 흡인 지수는 관심 영역에서 배경 영역의 계수치를 뺀 값으로 정의하였다. 결 과: 35명의 환아 중 23명에서 신티그래피상 위식도 역류가 관찰되었고, 정상 대조군 5명에서는 위식도 역류가 발견되지 않았다. 환아군 35명 중 24명에게 24시간 하부 식도 pH 검사를 시행하였고, 7명에서 산성역류가 확인되었다. 신티그래피와 하부 식도 pH 검사를 동시에 받은 24명 중 8명에서 두 검사의 결과가 일치하여 두 검사는 위식도 역류의 진단에 있어 일치하지 않았다. 환아군 35명 중 16명에게 흉부 전산화 단층 촬영을 시행하여 13명의 환아에서 의존성 위치에 폐 경화가 발견되어 흡인 폐렴으로 진단하였고, 이 환아들이 신티그래피에서도 폐 흡인이 있었는지 그 일치도를 알아보았을 때, 두 검사는 폐 흡인의 진단에 있어 일치하지 않았다. 한 명의 환아에서 6시간 후 지연 영상에 우폐로 역류된 방사능이 육안적으로 관찰되었다. 대조군과 비교하였을 때, 30명(85.7%)의 환아에서 흡인 지수가 결정점인 0.3보다 높아 폐 흡인의 가능성이 높은 것으로 진단하였다. 역류군과 비 역류군을 비교하였을 때, 6시간 후 지연 영상에서 흡인 지수는 역류군에서 유의하게 높았다(p<0.05). 결 론: 위식도 역류 신티그래피는 비 침습적이고 안전한 검사로 위식도 역류의 진단에 있어서는 24시간 하부 식도 pH 검사에 비하여 부족하지만 역류로 인한 소량의 폐 흡인을 진단하는데 유용하며, 앞으로 통계학적으로 의미 있는 수의 대조군 연구가 수행된다면 폐 흡인을 확진할 수 있는 진단 기준이 나올 것으로 생각된다.
