Acute eosinophilic pneumonia (AEP) is characterized by idiopathic acute febrile illness, diffuse pulmonary infiltration, severe hypoxemia, and pulmonary eosinophilia. We report a case of AEP associated with intramuscular administration of progesterone as luteal phase support after in vitro fertilization. A 33-year-old woman presented to our emergency room with tachypnea and hypoxemia, complaining of fever and cough for 4 days, and dyspnea for 2 days. The symptoms began 9 days after the first injection of progesterone. Chest radiograph showed bilateral infiltrates, located predominantly in the periphery of the lungs, with blunting of the costophrenic angle. Symptoms and chest radiograph dramatically improved after corticosteroid therapy and shifting the progesterone from an intramuscular form of administration to a vaginal form of administration.

간폐증후군은 간질환이 있는 환자에서 저산소증이 유발되는 상태로 폐내 혈관 확장으로 인해 폐내 동맥혈 산소공급에 결함이 발생하는 질환이다. 현재까지 간이식 외에 간폐증후군에 대한 다른 효과적인 치료법은 없는 것으로 알려져 있다. 국내에서는 간폐증후군의 증례 보고가 드물고, 특히 Child-Pugh 분류 A군에서의 발생 빈도는 낮은 것으로 보인다. 이에 저자들은 Child-Pugh 분류 A군인 대상성 간경화 환자에서 발생한 간폐증후군 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

Here we report the first fatality caused by H1N1 influenza virus infection with acute respiratory distress syndrome in Korea. A 55-year-old man presented at our emergency department with dyspnea, fever, diffuse myalgia and malaise. Bilateral lung air-space consolidation was detected on his initial chest radiograph combined with severe hypoxemia. He was supported by mechanical ventilation and treated with antibiotics. A nasopharyngeal aspirate was positive for influenza A rapid antigen and oseltamivir was started on day 3 of admission. The nasal swab sample was positive for influenza H1N1 virus by real-time reverse-transcriptase polymerase chain reaction. Despite aggressive treatment, he had refractory hypoxemia and uncontrolled septic shock. On day 5 of admission he went into cardiac arrest and expired.

Background: Acute pulmonary thromboembolism is fatal because of abruptly occurring hypoxemia and right ventricular failure. There are several treatment modalities, including anticoagulation, thrombolytics, ECMO (extracorporeal membrane oxygenator), and thromboembolectomy, for managing acute pulmonary thromboembolism. Materials and Methods: Medical records from January 1999 to December 2004 at our institution were retrospectively reviewed for pulmonary thromboembolectomy. There were 7 patients (4 men and 3 women), who underwent a total of 8 operations because one patient had post-operative recurrent emboli and underwent reoperation. Surgery was indicated for mild hypoxemia and performed with CPB (cardiopulmonary bypass) in a beating heart state. Results: The patients had several symptoms, such as dyspnea, chest discomfort, and palpitation. Four patients had deep vein thromboembolisms and 3 had psychotic problems, specifically schizophrenia. Post-operative complications included hemothorax, pleural effusion, and pericardial effusion. There were two hospital deaths, one each by brain death and right heart failure. Conclusion: Emergency operation should be performed when medical treatments are no longer effective.

Pulmonary alveolar proteinosis is a rare disorder in which lipoproteinaceous material accumulates within the alveoli. We report a case of pulmonary alveolar proteinosis in a 41 year old female patient. She complained of a dry cough in the preceding 6 months. She presented symptoms of mild hypoxemia and diffuse infiltration at both lower lung fields. A milky fluid was obtained by bronchoalveolar lavage. We confirmed by light microscopic examinations of the lung tissues obtained by transbronchial lung biopsy. Through several follow-ups, the patients symptoms were mild.

Rib fracture due to intense pain, may restrict patients from inadequate coughing. These conditions may produce varying degrees of complications such as atelectasis, pneumonia and arterial hypoxemia. Thoracic epidural analgesia has been used to treat pain associated multiple rib fractures because of its marked improvement in vital capacity and dynamic lung compliance. However, there are complications related to thoracic epidural analgesia which may include damage to spinal cord, perforation of dura, respiratory depression, decrease heart rate and arterial blood pressure. We experienced such a case of cardiac arrest during thoracic epidural analgesia while treating a patient for multiple rib fractures.

A previously healthy 57-year-old woman with dyspnea and wheezing presented to the emergency department a few minutes after exposure to unknown gas from mixing bleach (sodium hypochlorite) and cleaning agent (hydrochloric acid) at work place. Initial physical examination revealed severe wheezing on both whole lung fields, but the chest radiograph was normal. Arterial blood gas analysis showed only moderate hypoxemia. The patient was treated with oxygen, $\beta$adrenergic bronchodilators, antihistamines and corticosteroids, after then symptoms were improved. And the patient discharged against medical advice. We report a rare case of reactive airways dysfuntion syndrome from chlorine gas exposure.

Pulmonary arteriovenous fistula can occur in a variety of clinical situations including liver diseases, infections, metastatic carcinomas, systemic disorders, and after the palliation of congenital heart diseases. A 72-day-old male infant with Tetralogy of Fallot and pulmonary atresia underwent surgical correction without difficulty. However, ventilator weaning in the ICU failed initially because of an unexplained postoperative hypoxemia(FiO2: 0.8, PaO2: 40 mmHg, SaO2: 80∼90%). Postoperative follow-up lung perfusin scan at postoperative 15 days showed right-to-left shunt(33.6%) and ventilator weaning was performed on the 20th day after the operation (FiO2: 0.4, PaO2, 50mmHg, SaO2: 86.9%). Arterial oxygen saturation under room air was 80∼85% at 7 months postoperatively. One and half year follow-up lung perfusion scan showed decreased amount of right-to-left shunt (11.2%). We report a case with a review of the literatures.

Changes in the cardiovascular and bispectral index score were evaluated in dogs subjected to constant rate infusion (CRI) with alfaxalone. Fifteen dogs were assigned to three groups of 5. Groups and doses of alfaxalone were as follows: group 1, 3 mg/kg for induction and 6 mg/kg/h for CRI; group 2, 3 mg/kg for induction and 8 mg/kg/h for CRI; and group 3, 3 mg/kg for induction and 10 mg/kg/h for CRI. CRI was maintained for 1 h. Respiratory rates and blood pressures showed minimal changes; however, mild tachycardia and mild hypoxemia occurred, especially in group 3. There were some disparities between bispectral index score, electromyography and pedal withdrawal reflex test when measuring anesthetic depth. Additional premedications and/or analgesic agents would be helpful to avoid adverse effects of alfaxalone and provide improved cardiopulmonary functions.

Sleep-disordered breathing (SDB) is associated with increased cardiovascular and cerebrovascular morbidity. Epidemiological and clinic-based studies have shown that SDB is related to impaired glucose tolerance and increased insulin resistance, independent of obesity. Despite of a consistent association between SDB and impaired glucose-insulin metabolism, the mechanism underlying this relationship has not been fully elucidated. It is recognized that hypoxemia and hypercapnia that occur in SDB provoke sympathetic nervous activity and catecholamine, epinephrine and norepinephrine, and cortisol are released. Sympathetic hyperactivity and increased catecholamines can impair glucose homeostasis by increasing glycogenolysis and gluconeogenesis, which can result in increased circulating insulin levels and increased risk of insulin resistance. A prospective study is needed to investigate the causal relationship between SDB and impaired glucose-insulin metabolism in a healthy population without diabetes, hypertension and obesity as etiologic risk factors.
