Pulmonary infarction is rarely diagnosed with certainty except at postmortem examination. Part of this uncertainty is because of the inability to distinguish between hemorrhage, congestive a electasis, and necrosis clinically and radiographically. The pathogenesis of pulmonary infarction is poorly understood. It is dif%cult to induce pulmonary infarction in animals by ligation of the arterial supply to the lung. Many factors seem to be important in its pathogenesis, in addition to congestive heart failure, malignant tumor, thrombophlebitis, chronic obstructive lung disease, nephrotic syndrome, and postopeiative state. However, pulmonary infarction have not been reported in association with chest trauma. We report a case of pulmonary infarction associated with fractures of right clavicle and multiple ribs. A 45-year-old male had admitted due to right chest pain and dyspnea, which developed after right chest trauma occurred at about 3 weeks ago. He was treated at local clinics under the diagnosis of fractures of right clavicle and ribs until the admission. Chest CT disclosed a huge mass with central low density in right upper lobe, and small masses were also seen on both l ng fields. Open lung biopsy resulted in negativity for the malignancy. Clinical symptoms and radiological findings were not improved by conservative treatment. Right upper lobectomy was done eventually. The final diagnosis was pulmonary infarction. And, the patient has been well after operation.

The remaining lung infarction is a rare but life-threatening complication after a thoracic operation and trauma. We report a case of this rare complication after the left upper lobectomy due to pulmonary aspergilloma. The infarction of the remaining left lower lobe occurred due to kinking of the pulmonary vessels after the left upper lobectomy and the completion pneumonectomy was performed in the post-operative second day. Therefore, prompt diagnosis and treatment may be necessary to prevent morbidity and mortality associated with pulmonary infarction from torsion of pulmonary artery and vein.

Infarction of the lung usually results from pulmonary arterial obstruction. Pulmonary infarcts often become infected from bronchial contamination and may become lung abscesses, empyema, or bronchopleural fistula causing sepsis. Diagnosis is important for intensive therapy, since infection is prone to spread. Resection of the infarcted lung should be considered early in an attempt to control infection. A sixty-seven-year-old man was hospitalized with dyspnea. A computed tomographic scan of the chest showed left lower lobe infiltration and mild pleural effusion with pleural thickening. There was a thrombus in the left pulmonary artery leading from the lower lobe to the upper lobe artery. At operation, the left lower lobe was found to have complete hemorrhagic infarction. The left lower lobectomy was performed. The remaining thrombus was removed after the left main pulmonary arteriotomy. He has been followed up for 15 months and has done well with no recurrence of thrombus and infarction of the lung.

Tadalafil is a phosphodiesterase-5 inhibitor (PDE5I), which is widely used to treat erectile dysfunction. Although PDE5Is have excellent safety profiles, and most of the side effects are mild, rare serious adverse events have been reported in association with PDE5Is. Thrombosis is one of those events, and a few previous reports have suggested the association of PDE5Is with thrombosis. We report the case of a 61-year-old male who developed pulmonary embolism combined with pulmonary infarction directly after taking tadalafil. Both the patient and the physician suspected tadalafil as the culprit drug, as the patient was in an otherwise healthy condition. However, after extensive evaluation, we noticed that factor VIII levels were elevated. Prior reports suggesting the association between thrombosis and PDEIs either lack complete information on coagulation factors, or show inconsistencies in their results. Physicians should operate caution prior to accepting the diagnosis of adverse drug reaction.

Objectives : The characteristic of meridian system has been similar to this of electric potentials in human body. Therefore to measure the electric potentials in healthy volunteers and patients, and to find out the characteristic of meridian system and also to do that of differences between them. Methods : Twenty-nine healthy volunteers, thirty patients diagnosed as a cerebral infarction and wind-syndrome caused by hyperactivity of the liver-yang(肝陽化風) were examined into electric potential of well(井穴) and sea(合穴) points in branches of the twelve meridians by physiograph. Results : Measurements were analyzed by factor analysis, then we obtained that both the right and the left electric potential of well and sea points in branches of the twelves meridians in healthy volunteers were divided into two factors, hand meridian and foot meridian. Where as the left electric potential of those in patients with cerebral infarction were divided into three factors, one is foot meridian, another is hand meridian with the exception of large intestine meridian, and the other is large intestine meridian and also the right electric potential were divided into three factors, foot meridian, hand meridian with the exception of large intestine and lung meridian, and large intestine and lung meridian. Conclusions : In the results, healthy volunteers differ from patients in characteristic of electrical potentials, which means that we are able to catch the characteristic of meridian system by electrical potentials of well and sea points.

We report a case of a 5-year-old girl who developed left hemiparesis and left facial palsy, 6 days after the initiation of fever and respiratory symptoms due to pneumonia. Chest radiography, conducted upon admission, showed pneumonic infiltration and pleural effusion in the left lung field. Brain magnetic resonance imaging showed acute ischemic infarction in the right middle cerebral artery territory. Brain magnetic resonance angiography and transfemoral cerebral angiography revealed complete occlusion of the right middle cerebral artery. Mycoplasma pneumoniae infection was identified by a 4-fold increase in IgG antibodies to M. pneumoniae between acute and convalescent sera by enzyme-linked immunosorbent assay. Fibrinogen and D-dimer levels were elevated, while laboratory exams in order to identify other predisposing factors of pediatric stroke were all negative. This is the first reported pediatric case in English literature of a M. pneumoniae-associated cerebral infarction involving complete occlusion of the right middle cerebral artery.

The relationship between neoplastic disease and thromboembolic disorders has been recognized since 1865, when Armand Trousseau first reported a high incidence of venous thrombosis in a series of patients with gastric carcinoma. The overall incidence of thromboembolic disease in patients with cancer has been reported to vary 1% to 15%. In a prospective study, Ambrus and associates reported that thrombosis and/or bleeding was the second most common cause of death in haspitalized cancer patients. We report a case who presented as a thromboembolic disease and subsequently confirmed to have an underlying lung malignancy. This 45 years old male patient visited our hospital with abdominal pain and distention of 3 days duration. Abdominal CT scan revealed multiple splenic and renal infarctions. On 20th haspital day, drowsy mental status was developed and hemorrhagic cerebral infarction was noted in brain CT scan. Chest CT scan revealed a 4cm sized spiculated mass on left lung apex and multiple paratracheal lymph adenopathy. With surgical biopsy of left supraclavicular lymph nodes, this patient was confirmed to have adenocarcinoma.

There are few topic about a pulmonary thromboembolism(PTE) especially in Korean medical research. This case report is dealt with a rare situation that a PTE and a lacunar infarction are complicated in one patient. They have a similarity in that both are caused by the thrombosis. The former is the thrombosis in lung and the latter is the cerebral infarcion within the territory of a single perforating artery Recently the attack rate of PTE somewhat grow because of the development of medicine such as the increasing use of indwelling catheters, trauma or surgery of pelvis and lower extrimity, major surgery especially in senior, the use of estrogen containing compounds, cerebrovascular disease, obesity, etc. A 70 year-old lady was stroked by the cerebral infarction and has been getting rehabilitating therapy. She had the sudden onset of dyspnea, chest pain and those symptoms looked like a myocardial infarction. But she was diagnosed as PTE by ventilation perfusion lung scan. We cured her with the integrated therapy of Korean and Western medicine.

An eight-year-old boy was referred to our hospital with cough and high fever. His past medical history included a small sized ventricular septal defect (VSD) at birth. Transthoracic echocardiography disclosed a 10 x 6 mm vegetation on tricuspid valve, a small VSD and the moderate tricuspid valve insufficiency were found. Blood cultures grew methicillin-resistant staphylococcus aureus. Despite proper antibiotic therapy, fever was not controlled and his course was complicated by pulmonary infarction. The patient simultaneously underwent pulmonary resection and open heart surgery. Through the median sternotomy we performed open thrombectomy and lobectomy (right lower lobe) at first, and then vegetectomy, tricuspid valve repair, and direct closure of VSD were done under cardiopulmonary bypass.

We have performed left lung transplantations in 15 dogs for one year and six months from June, 1990 to December, 1991 at the Repartment of Thoracic and Cardiovascular Surgery Yonsei University College of medicine, Seoul, Korea. These dogs were sacrificed at from operative day to post-operative 15 days when their general conditions were deteriorated. The gross findings of the transplanted lungs were thrombi in left atrium in three cases, partial occlusion of pulmonary artery or pulmonary veins in three cases, hemorrhage at pulmonary arterial anastomotic site in one case and bronchial anastomotic stenosis in two cases, bronchial anastomotic rupture in one case % no abnormal gross findings in four cases. The microscopic findings of the transplanted lungs were hemorrhagic infarction in one case, perivascular hemorrhage or pulmonary edema in two cases, peribronchial inflammatory cell infiltration & pneumonia in three cases, and alveolar type rejection with infiltration of type II pneumocytes and septal thickening in 3 cases. And also there were no abnormal findings including rejection or inflammatory evidences in six cases. The one among these six dogs survived to 15 days without evidence of rejection or inflammatory reaction & died due to postoperative care accident.
