  • Acute respiratory distress syndrome (ARDS) is a common cause of severe hypoxemia defined by the acute onset of bilateral non-cardiogenic pulmonary edema. The diagnosis is made by defined consensus criteria. Supportive care, including prevention of further injury to the lungs, is the only treatment that conclusively improves outcomes. The inability to find more advanced therapies is due, in part, to the highly sensitive but relatively non-specific current syndromic consensus criteria, combining a heterogenous population of patients under the umbrella of ARDS. With few effective therapies, the morality rate remains 30% to 40%. Many subphenotypes of ARDS have been proposed to cluster patients with shared combinations of observable or measurable traits. Subphenotyping patients is a strategy to overcome heterogeneity to advance clinical research and eventually identify treatable traits. Subphenotypes of ARDS have been proposed based on radiographic patterns, protein biomarkers, transcriptomics, and/or machine-based clustering of clinical and biological variables. Some of these strategies have been reproducible across patient cohorts, but at present all have practical limitations to their implementation. Furthermore, there is no agreement on which strategy is the most appropriate. This review will discuss the current strategies for subphenotyping patients with ARDS, including the strengths and limitations, and the future directions of ARDS subphenotyping.

  • 간세포암에 이환된 61세 남자에서 lipiodol과 doxorubicin을 이용하여 간동맥 항암 화학 색전술을 시행하였고 3일 후 급성 호흡 부전증이 발병하였으며 임상 양상 및 방사선학적 소견상 급성 폐부종 및 폐렴에 의한 급성 폐손상에 합당하였다. 감염, 혈전 및 종괴에 의한 폐색전증, 울혈성 심부전에 의한 급성 호흡 부전증의 가능성을 배제하기 위하여 혈액, 객담 배양 검사를 시행하였으나 균주는 동정되지 않았고 복부 전산화 단층 촬영, 복부 핵자기 공명 영상, 심 초음파 등을 시행하였으나 심장이나 하대 정맥에서 종괴나 혈전을 발견할 수 없었으며 심기능은 정상이었다. 상기 소견으로 본 환자의 급성 호홉 부전증의 원인으로서 lipiodol에 의한 폐 지방전색증을 추정하게 되었다. 환자는 보전적 요법을 시행받고 증상 발현 4주 후 임상증상 및 흉부 단순 촬영상 호전을 보여 퇴원하였다. 저자 등은 lipiodol과 doxorubicin을 이용하여 간세포암의 화학색전술을 시행 후 lipiodol에 의한 폐지방 색전증이 원인인 급성 폐손상이 발생한 종례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

  • Pathological studies on 6 milk goats administrated with urea were carried out to determine the effects of acute and chronic poisonings on the animal. Clinical signs appeared about 10 minutes after ingestion of the urea and they consisted chiefly in dullness, staggering, uncontrolled urination, dyspnea, frothy salivation, bloating, muscular tremor, humping of back and tetanic spasms. Macroscopic lesions were failure of blood clot, frothy and bloody contents in the highly congested respiratory tract, pulmonary edema, rumenitis and abomatitis accompanying with petechiation of the upper small intestine. Microscopically, the liver showed vacuolar degeneration, fatty change and areas of necrosis and partial proliferation of the interlobular connective tissues in chronic crises. The renal epithelium displaced vacuolar degeneration, necrosis and hyaline casts in their lumens. In the lungs, there were hyperemia, edema, hemorrhages, and acute catarrhal bronchitis. Neuronal degeneration and necrosis in the central nervous system, catarrhal rumenitis, abomatitis, doudenitis and myocardial hemorrhage were also demonstrated.

  • The tetralogy of Fallot is one of the most frequent and serious congenital cardiac malformation accompanied cyanosis. For relief of cyanosis, the Waterston operation is a successful, palliative procedure in infant & young child under age of five with obstructive lesions of the right: side of the heart who require a systemic-pulmonary arterial shunt for survival. A patient, aged 3 and weighing 13 kg., who had been cyanotic since one month after birth,. was admitted to the University of Severance Hospital under a diagnosis of tetralogy of Fallot, The side to side anastomosis between the right pulmonary artery & the ascending aorta was performed in March 1976. The anastomotic channel was made only 4 ram. in diameter, thereafter massive unilateral pulmonary congestion on the side of the anastomosis developed shortly after operation. And the. patient died of congestive heart failure within a hour. And so the purpose of this report is describe the immediate & late effect of systemic-pulmonary shunt for T.O.F. with review of literatures.

  • 연구배경 : 급성폐손상 환자는 폐의 염증 및 투과성 증가로 폐부종을 보인다. 폐부종의 중요한 결정요인은 폐모세혈관압이며 호기말양압은 폐모세혈관에 영향을 미치는 것으로 알려져 있다. 최근 폐동맥 풍선 도자를 이용한 임상적인 폐모세혈관압 측정법이 발전하여, 이를 이용 하면 폐동맥쐐기압 뿐만 아니라 폐모세혈관압 측정도 가능하게 되었다. 이에 급성폐손상 환자를 대상으로 폐동맥 풍선 도자로 폐동맥쐐기압 및 폐모세혈관압의 변화를 관찰하여 폐동맥쐐기압이 폐모세혈관압올 적절히 반영하는지 알아보고, 호기말양압의 변화가 폐모세혈관압에 미치는 영향을 알아보고자 본 연구를 시행 하였다. 방법 : 급성폐손상으로 기계호흡을 받은 11명의 환자를 대상으로 하였다. 호기말 양압을 0cm$H_2O$에서 시작하여 15분 간격으로 4cm$H_2O$ 씩 증가시켜 12cm$H_2O$까지 변화를 주연서 정해진 PEEP값에서 폐동맥 풍선 도자를 이용한 폐모세혈관압 측정법을 사용하여 자료를 얻었다. 결과 : 호기말양압을 0cm$H_2O$부터 12cm$H_2O$까지 증가시킴에 따라 중심정맥압은 $6.1{\pm}1.6$에서 $9.3{\pm}2.3$mmHg까지 증가하였고, 평균폐동맥압도 $22.7{\pm}7.4$에서 $25.3{\pm}7.3$mmHg까지 증가하였다. 또한 폐동맥쐐기압은 $9.8{\pm}2.1$ 에서 $12.8{\pm}2.1$mmHg로 증가하였고, 폐모세혈관압도 $15.3{\pm}3.3$ 에서 $17.8{\pm}3.2$mmHg로 증가 하였다. 결론 : 급성폐손상 환자에서 폐동맥쐐기압이 폐모세혈관압을 반영하나 호기말양압을 사용하면 폐모세혈관압이 증가하는 것을 관찰하였다. 따라서 급성폐손상 환자의 수액요법에서 폐동맥쐐기압 뿐만 아니라 폐모세혈관압의 감시도 가치가 있을 것으로 기대된다.

  • Acute respiratory failure has become an increasingly frequent cause of death following shock or trauma. Interstitial or diffuse alveolar edema, as chief pathophysiologic change of acute respiratory insufficiency, can be the result of sepsis, fat embolism, cardiac failure, lung congestion, and oxygen toxicity. These pulmonary problems are extremely difficult to treat without early recognition of their development and aggressive management. If the treatment is delayed, the progressive respiratory failure is almost uniformly fatal. Authors have experienced two cases of acute respiratory insufficiency following the blunt chest trauma, which were healed uneventfully. Literatures were briefly reviewed.

  • Since the outbreak of the enterovirus 71 (EV71) infection in Malaysia in 1997, large epidemics of EV71 have occurred in the Asia-Pacific region. Many children and infants have died from serious neurological complications during these epidemics, and EV71 infection has become a serious public health problem in these areas. EV71 infection causes hand, foot and mouth disease (HFMD) in children, and usually resolves spontaneously. However, EV71 occasionally involves the central nervous system (CNS), and induces diverse neurological complications such as brainstem encephalitis, aseptic meningitis, and acute flaccid paralysis. Among those complications, brainstem encephalitis is the most critical neurological manifestation because it can cause neurogenic pulmonary hemorrhage/edema leading to death. The characteristic clinical symptoms such as myoclonus and ataxia, cerebrospinal fluid (CSF) pleocytosis, and brainstem lesions on magnetic resonance imaging, in conjunction with the skin rash of HFMD and the isolation of EV71 from a stool, throat-swab, or CSF sample are typical findings indicating CNS involvement of EV71 infection. Treatment with intravenous immunoglobulin and milrinone are recommended in cases with severe neurological complications from EV71 infection, such as brainstem encephalitis. Despite the recent discovery of receptors for EV71 in human cells, such as the scavenger receptor B2 and P-selection glycoprotein ligand 1, it is not known why EV71 infection predominantly involves the brainstem. Recently, 3 companies in China have completed phase III clinical trials of EV71 vaccines. However, the promotion and approval of these vaccines in various countries are problems yet to be resolved.

  • A 4-year-old neutered female domestic shorthair cat weighing 5.1 kg was referred to Jeju National University Hospital with acute onset respiratory distress, weakness, and anorexia. The patient had a history of stressful antecedent events that involved bullying by a newly introduced cat. Thoracic radiography and echocardiography revealed a stage C hypertrophic cardiomyopathy phenotype based on the American College of Veterinary Internal Medicine classification system with pulmonary edema, pleural effusion, and pericardial effusion at the same time. The patient was treated with furosemide, pimobendan, and rivaroxaban. Pericardiocentesis was performed because pericardial effusion was identified. Reevaluation after 30 days revealed a normal respiratory rate on physical examination, normal cardiac shape on thoracic radiographs, and normal cardiac measurements on echocardiography. The patient was tentatively diagnosed with transient myocardial thickening (TMT) and all medications were discontinued. Six months after the initial hospitalization, the cat continued to do well without any clinical signs or left ventricular wall thickening. This case is the first report describing feline TMT in Korea. Moreover, it involves a rare case in which pulmonary edema, pleural effusion, and pericardial effusion, which induce cardiac tamponade, occurred simultaneously due to TMT-related congestive heart failure.

  • Background: TNF-$\alpha$ plays a major role in producing left ventricular dysfunction cardio-myopathy pulmonary edema and inhibits the compensatory mechanism of congestive heart failure. IL-6 is an acute reactant of immune reaction and also known to control immune reaction but its function in the myocyte was not clearly investigated. Author's performed this experiment to investigate the contents of TNF-$\alpha$ and IL-6 on the assumption that TNF-$\alpha$ and IL-6 may reside in nonfailing heart that has gone cardiac surgery and play some role in cardiac function. Material and Method : Right auricular tissues were sampled from 12 patients who had undergone total corrective surgery for both congenital and acquired heart diseases from January 1998 to June 1998 in Kosin Universcfy Gospel hospital. The quantitive analysis of TNF-$\alpha$ and IL-6 were assessed by ELISA method in right auricular tissue. Hemodynamic values about the pressure of ventricle atrium aorta pulmonary artery and cardiac index pulmonary and systemic vascular resistance and cardiac output were measured by echocardiography and cardiac catheterization and biochemical analyses of LDH & AST were done before operation. statistical analysis was by Paired Student t-test. Patients were divided into children(under 15 years olds) and adults groups and the data was compared beween two groups. Conclusion: Mild pulmonary hypertension and increased pulmonary vascular resistance were existed in both group. The contents of tissue TNF-$\alpha$ IL-6 in each group were independent of each data.
