Brain abscess commonly occurs secondary to an adjacent infection (mostly in the middle ear or paranasal sinuses) or due to hematogenous spread from a distant infection or trauma. Pulmonary arteriovenous fistulas (AVFs) are abnormal direct communications between the pulmonary artery and vein. We present two cases of brain abscess associated with asymptomatic pulmonary AVF. A 65-year-old woman was admitted with a headache and cognitive impairment that aggravated 10 days prior. An magnetic resonance (MR) imaging revealed a brain abscess with severe edema in the right frontal lobe. We performed a craniotomy and abscess removal. Bacteriological culture proved negative. Her chest computed tomography (CT) showed multiple AVFs. Therapeutic embolization of multiple pulmonary AVFs was performed and antibiotics were administered for 8 weeks. A 45-year-old woman presented with a 7-day history of progressive left hemiparesis. She had no remarkable past medical history or family history. On admission, blood examination showed a white blood cell count of 6290 cells/uL and a high sensitive C-reactive protein of 2.62 mg/L. CT and MR imaging with MR spectroscopy revealed an enhancing lesion involving the right motor and sensory cortex with marked perilesional edema that suggested a brain abscess. A chest CT revealed a pulmonary AVF in the right upper lung. The pulmonary AVF was obliterated with embolization. There needs to consider pulmonary AVF as an etiology of cerebral abscess when routine investigations fail to detect a source.

Tocolytics 임신부의 조기진통시 치료제로 많이 사용되는 약제지만 드물게는 폐부종을 일으켜 치명적일 수 있다. Tocolytics가 폐부종을 일으키는 기전은 용적증가, 교질삼투압의 감소, 심근 손상, 모세혈관 내막의 손상등에 의해 발생한다고 설명되고 있으나 아직 불확실한 상태이며 폐부종 발생의 양대 기전인 정수압적 폐부종과 투과성 폐부종의 양상이 모두 관여하는 것으로 알려져 있다. 또한 임산부가 다산부이거나 다태아 임신인 경우, 임신중 수액공급을 많이 받은 경우, 심장 질환이 동반된 경우, 감염이 동반된 경우, 동시에 steroid나 MgSO4로 치료 받은 경우등이 tocolytics 사용시 폐부종이 쉽게 발생될 수 있는 선행요인으로 작용함이 알려져왔다. 저자들은 조기진통이 있어 tocolytics인 ritodrine 치료후 정상분만하였으나 분만후 급속히 진행하는 폐부종이 발생한 30세 여자 환자를 경험하였기에 문헌고찰과 함께 보고하는 바 이다.

The results about effects of Maecmoondongtang on the pulmonary function of $SO_2$ exposed rats were summerized as follows: 1. Maecmoondongtang reavealed significant effect on decrease of the lung weight in pulmomary edema of rats. 2. Maecmoondongtang reavealed very significant effect on decrease of the TBA value of lung. 3. It was recognized Maecmoondongtang had signiftcant effect on decrease of glycoprotein contents in trachea. 4. It was recognized maecmoondongtang had significant effect on decrease of mucos area in tracheal epithelium. 5. Maecmoondongtang had effects on recovery of the cillia cells of tracheal epithelium and inhibition of mucous secretion. According to the above result. it was recognized Gamimaecdongtang had significant effect on decrease of lung weight in pulmonary edema. the TBA value. glycoprotein contents in trachea. and mucous area in tracheal epithelium. and recovery of the cillia cells of tracheal epithelium. and inhibition of mucous secretion. So I think we can take advantage of this medicine very usefully for treatment of pulmonary edema. pheumonia. acute and chronic bronchitis etc.

The effect of reticuloendothelial hyperfunction on hypothermic preservation of lung was studied in dogs. In order to evaluate the viability after hemodynamic_ load in preserved isolated lung, observations were made on the rate of increase in weight, degree of edema,compliance and surface activity of lung. The results obtained as follows: l. In the group of activating of the reticuloendothelial system by injection of sodium thiosulfate intravenously before pneumonectomy and infusion of naphthionine through the pulmonary artery before hypothermic preservation of isolated lung the limit of preservation was eight hours whereas four hours in non-treated control group. 2.Therefore the method of activating of the reticuloendothelial system before and after pulmonary resection seems effective in preserving for prolonging the period of preservation of lung by means of inhibition of pulmonary edema. 3. Pulmonary surface activity is expected to be valuable as a method in evaluation of the viability of preserved lung along with compliance and rate of increase in weight of lung.

Although re-expansion pulmonary edema (RPE) is rare (incidence rate <1%), it is associated with a mortality rate of >20%; therefore, early diagnosis and treatment are important. We report a case of RPE following chest tube insertion in a patient with spontaneous pneumothorax. We have specifically focused on the mechanism underlying RPE and the possible etiology. An 82-year-old man with a history of chronic anemia, chronic obstructive pulmonary disease, diabetes mellitus, and hypertension was referred to the emergency department for management of recurrent right-sided pneumothorax. We performed emergency closed thoracostomy for suspected tension pneumothorax, which led to stabilization of the patient's vital signs; however, he coughed up frothy pink sputum accompanied by severe right-sided chest pain 30 min postoperatively. The patient showed new-onset right pulmonary consolidation on chest radiography, as well as desaturation, tachycardia, and tachypnea and was diagnosed with RPE. He was transferred to the intensive care unit for mechanical ventilation and supportive treatment using diuretics, ionotropic agents, and prophylactic antibiotics. RPE gradually resolved, and the patient was extubated 3 days after admission. He has not experienced recurrent pneumothorax or pulmonary disease for 4 months. We emphasize the importance of RPE prevention and that aggressive ventilator care and supportive treatment can effectively treat RPE following an accurate understanding of the underlying pathogenetic mechanisms and risk factors.

Background: No consensus exists regarding whether volatile anesthetics are superior to intravenous anesthetics for reducing postoperative pulmonary complications (PPCs) in patients undergoing general anesthesia for surgery. Studies of this issue focused on anatomic pulmonary resection are lacking. This study compared the effects of total intravenous anesthesia (TIVA) versus volatile anesthesia on PPCs after anatomic pulmonary resection in patients with lung cancer. Methods: This retrospective study examined the medical records of patients with lung cancer who underwent lung resection at our center between January 2018 and October 2020. The primary outcome was the incidence of PPCs, which included prolonged air leak, pneumonia, acute respiratory distress syndrome, empyema, atelectasis requiring bronchofiberscopy (BFS), acute lung injury (ALI), bronchopleural fistula (BPF), pulmonary embolism, and pulmonary edema. Propensity score matching (PSM) was used to balance the 2 groups. In total, 579 anatomic pulmonary resection cases were included in the final analysis. Results: The analysis showed no statistically significant difference between the volatile anesthesia and TIVA groups in terms of PPCs, except for prolonged air leak. Neither of the groups showed atelectasis requiring BFS, ALI, BPF, pulmonary embolism, or pulmonary edema after PSM. However, the length of hospitalization, intensive care unit stay, and duration of chest tube indwelling were shorter in the TIVA group. Conclusion: Volatile anesthetics showed no superiority compared to TIVA in terms of PPCs after anatomical pulmonary resection in patients with lung cancer. Considering the advantages of each anesthetic modality, appropriate anesthetic modalities should be used in patients with different risk factors and situations.

연구배경 : 급성 폐손상은 원인에 상관없이 병태생리학적으로 폐동맥압의 증가와 폐부종을 특징으로 하는데 산소기를 포함한 여러 종류의 염증매개성 물질들이 급성 폐손상의 발병기전에 관여할 것으로 생각되고 있다. 그러나 산소기에 의한 급성 폐손상에서 폐모세혈관압의 변화는 확실하게 알려져 있지 않다. 또한 폐부종의 형성에는 폐포-모세혈관투과성과 함께 폐모세혈관과 폐포사이의 수압차도 중요한 역할을 하는 것으로 알려져 있으나 산소기에 의한 급성 폐손상에서 폐포모세혈관압의 역할에 관해서는 별로 알려져 있지 않은 실정이다. 방법 : Sprague-Dawley 백서를 정상 대조군(n=5), xanthine/xanthine oxidase 처치군(n=7), catalase 전치치군(n=5), papaverine 전처치군(n=7)과 indomethacin 전처치군(n=5)으로 나누어 격리순환폐모델에서 시간경과 따른 폐동맥압, 폐모세혈관압을 측정하고 폐의 무게 변화를 관찰하여 폐부종의 지표로 사용하였다. 폐모세혈관압은 micropuncture에 의한 방법과 일치도가 높은 것으로 알려져 있는 double occlusion법을 이용하였다. 즉, 폐동맥으로의 관류와 좌심방으로부터의 관류를 동시에 2초간 차단하여 폐동맥압과 좌심방압이 비슷한 압력에서 평형상태를 유지할 때의 압력을 폐모세혈관압으로 사용하였다. 결과 : 1) 폐동맥압과 폐모세혈관압은 각각 xanthine/xanthine oxidase 처치군에서 대조군에 비해 유의하게 높았다. 이들은 catalase와 papaverine 전처치로 각각 유의하게 완화되었으나 indomethacin 전처치로는 유의하게 완화되지 않았다. 2) xanthine/xanthine oxidase 처치군에서 관찰된 폐부종은 catalase 천처치와 papaverine 전처치로 유의하게 완화되었으나 indomethacin 전처치로는 완화되지 않았다. 결론 : 격리순환폐모델에서 산소기에 의한 백서의 급성 폐손상시 폐모세혈관압이 증가하고 이는 폐포-모세혈관투과성이 증가된 상태하에서 폐부종을 악화시키며 산소기에 의한 폐모세혈관압의 증가와 폐부종에 cyclooxygenase 대사물은 큰 역할을 하지 않을 것으로 생각된다.
