A 43 year-old black man with sickle cell trait documented by hemoglobin electrophoresis presented with severe pleuritic chest pain and hypoxemia three weeks after discharge following abdominal surgery. A pulmonary embolus was diagnosed by angiography and he was treated with heparin; the minimum arterial pO2 was 55 torr while O2 was being administered at a rate of 3 L/min. During this therapy, he developed abdominal pain. Computerized tomography suggested splenic infarction, which was documented by radionuclide liver-spleen scan and magnetic resonance imaging (MRI); the patient's spleen had been normal at exploratory laparotomy three weeks previously. No source for emboli was identified in the deep venous system by MRI. Although splenic infarction has been reported in patients with sickle cell trait at high altitude, this is the first reported case of splenic infarction secondary to the hypoxemia of pulmonary embolism in a patient with sickle cell trait. The spleen is subject to infarction in sickle cell trait because blood flow is slow through a hypoxemic and acidemic environment. The additional hypoxemia due to pulmonary embolism is presumed, in our patient, to have created a local splenic environment which permitted infarction to occur.

Between August 1982 and December 1985, seven patients at a children's hospital developed hospital-acquired pneumonia caused by Legionella pneumophila. Demographic data included the following: mean age 12.3 years (range 9 months to 20.5 years); male/female ratio 5:2; all patients were white. Some previously identified risk factors present in our patients included high-dose corticosteroid therapy (five patients), other immunosuppressive therapy (four), and chronic lung (five) or kidney (three) disease. Symptoms and signs included rapid onset, fever, cough, pleuritic chest pain, dyspnea, abdominal pain, diarrhea, and headache. Rhinitis, myalgia, and neurologic abnormalities were not noted. Chest roentgenograms revealed single-lobe consolidation in three patients, diffuse bilateral alveolar infiltrates in three, and pleural effusion in three. All patients were treated with erythromycin; three patients also received rifampin. Tracheal intubation and mechanical ventilation were required by four patients. Six patients improved after therapy. One child died of persistent lung disease 1 month after the onset of legionnaires disease. L. pneumophila was isolated from potable water in the hospital. Aerosol equipment cleansed with tap water and the showers were implicated as means of exposure by patients to contaminated potable water. No new nosocomial cases were seen after immunocompromised children were prohibited from taking showers, and sterile water was used to cleanse equipment for administering aerosol medications.

Case reports are presented on 2 patients to show the importance of following up apparently false positive results of pregnancy tests. In case 1, a 25-year-old woman was admitted to the hospital with severe breathlessness in September 1987. After she had stopped using oral contraceptives (OCs) in 1985 her periods were irregular and on 4 occasions the results of pregnancy tests bought over the counter were positive. She was twice referred for ultrasound examinations, but the uterus was empty each time. In April 1987, dysfunctional uterine bleeding was diagnosed; she was treated with clomiphene. She then experienced intermittent pleuritic chest pain and breathlessness on exertion. In early September she was admitted with acute breathlessness and chest pain. A further pregnancy test was positive; results of laparoscopy of the pelvis were normal. A radioisotope ventilation-perfusion lung scan showed multiple filling defects in the left lung and no perfusion to the right. A presumptive diagnosis of choriocarcinoma was made with the syndrome of tumor growing in the pulmonary arteries. In case 2, a 32-year-old woman was admitted to the hospital in March 1988 with acute lower abdominal pain. A pregnancy test was positive, and she underwent laparoscopy for suspected ectopic pregnancy. A macroscopic tumor was found on the surface of the right ovary and a right salpingo-oophorectomy was performed. A subsequent histological examination showed choriocarcinoma. The 2 cases reported show the importance of seeking a definitive explanation for a false positive result of a pregnancy test. If the test has been performed correctly and proteinuria and drug interference, for instance, are ruled out, then a raised human chorionic gonadotropin concentration, particularly in young women, is virtually certain. In most cases this will be due to a pregnancy that ends in a 1st trimester abortion, but in a small minority it will be due to the hormone producing a tumor such as choriocarcinoma.

Enteroviruses were isolated from feces and/or cerebrospinal fluid of 29 of 43 Toronto children who contracted aseptic meningitis, pleurodynia, abdominal pain or febrile upsets between June and October, 1965. Coxsackie A9 virus was the dominant agent in aseptic meningitis and Coxsackie B1 virus in pleurodynia and other syndromes. Sero-logical evidence of recent Coxsackie B1 and Echo 6 infection was obtained in two additional patients with aseptic meningitis who did not yield virus, and elevated Coxsackie B1 antibody titres were found in one patient with pericarditis. A newborn infant died with myocarditis due to Coxsackie B1 virus following infection of the mother during the immediate antenatal period. Paired sera collected only two to four days apart from patients with enteroviral syndromes or mumps meningoencephalitis frequently showed four-fold or greater increases of antibody levels.

A 45-year-old woman developed chronic urticaria clinically and cutaneous necrotizing vasculitis histologically, with arthralgias, abdominal pain, angioedema, hemoptysis, and pleuritic chest pain. An open lung biopsy revealed a leukocytoclastic vasculitis of the pulmonary venules, which may be etiologically associated with the chronic obstructive lung disease detected in this patient by pulmonary function tests. The documentation of pulmonary disease in patients with urticarial vasculitis emphasizes the potentially serious nature of this disorder and the need for careful diagnosis and prompt, vigorous treatment.

A 35-year-old man presented with cough, expectoration of green sputum, and right-sided pleuritic chest pain. Symptoms had begun the previous day and he had vomited the night before. The patient also complained of chronic fatigue, a 12-lb. weight loss, insomnia, right-sided back pain, and lower extremity myalgias. He denied having had fever, chills, diaphoresis, dyspnea, diarrhea, dysuria, abdominal pain, skin lesions, or jaundice.

Internal pancreatic fistulas are rare but debilitating complications of chronic pancreatitis. Fistulous tracts from the pancreatic duct to the peritoneal or pleural cavities have been treated by medical therapy and surgical management, with success rates of 41% and 89%, respectively. Endoscopic stent placement for internal and external pancreatic fistulas has also been shown effective. We report on three patients with histories of chronic alcohol abuse and pancreatitis. Two patients presented with dyspnea and pleuritic chest pain. Imaging studies revealed pleural effusions, and endoscopic retrograde cholangiopancreatography (ERCP) demonstrated a patent fistulous tract from the pancreatic duct to the pleural cavity in each patient. Chemical analysis of the pleural fluid indicated pancreatic origin. The third patient, who had left-upper-quadrant abdominal pain and a small pleural effusion, had a large noncommunicating pseudocyst adjacent to the stomach. Nasopancreatic drains, along with chest tube drainage, were placed in the patients with pancreatic pleural fistulas. The patient with the pseudocyst received nasocystic drainage via the stomach. Drainage was measured until closure of the fistulas or cyst. Additionally, simply by injecting contrast medium, we were able to monitor the closure of fistulas without ERCP. The fistulas closed within 7 days, and the pseudocyst resolved within 14 days. Following discharge, all three patients were pain free, without evidence of recurrent fistulas or pseudocyst. In conclusion, the use of nasopancreatic/cyst drainage is an effective and convenient way to treat internal, communicating collections and pseudocysts of pancreatic origin. Furthermore, this method provides a simple means of assessing closure of fistulas and pseudocysts.

May-Thurner syndrome is an uncommon process in which the right common iliac artery compresses the left common iliac vein, resulting in left iliofemoral deep vein thrombosis and severe leg edema. We report the case of a 41-year-old female who presented with severe left leg edema present for 1 day. One week earlier she had experienced acute shortness of breath and pleuritic chest pain. Duplex ultrasound revealed a left iliofemoral deep vein thrombosis. A computed tomography (CT) scan performed for abdominal pain revealed thrombosis of the entire left common and external iliac veins. A ventilation-perfusion scan diagnosed a pulmonary embolism. The patient was treated with systemic intravenous heparin and catheter-directed thrombolysis of the iliofemoral deep vein thrombosis. Complete thrombolysis and iliofemoral vein patency was achieved over 5 days. A persistent stenosis in the left common iliac vein consistent with May-Thurner syndrome was alleviated with percutaneous balloon angioplasty and placement of a Wallstent. Heparin therapy was terminated at the time of stenting because of suspected heparin-induced thrombocytopenia. The patient was started on a continuous infusion of 10% dextran 40, and warfarin therapy was initiated. Heparin-induced antibodies were confirmed by a C-14 serotonin release assay. The endovascular reconstruction remains patent 4 months later. Heparin-induced thrombocytopenia complicating endovascular reconstruction of the iliofemoral venous system in a patient with May-Thurner Syndrome is an uncommon occurrence. This case and a review of the literature are discussed.

The aim of this study was to evaluate the efficacy and toxicity of low-dose methotrexate with folinic acid rescue in a large series of consecutively treated patients with low-risk persistent gestational trophoblastic disease. Between January 1987 and December 2000, 250 patients were treated with intramuscular methotrexate (50 mg on alternate days 1, 3, 5, 7) with folinic acid (7.5 mg orally on alternate days 2, 4, 6, 8) rescue. The overall complete response rate without recurrence was 72% for first-line treatment and 95% for those who required second-line chemotherapy. Eight women (3.2%) had recurrence following remission and two (0.8%) had new moles. Two women (0.8%) died of their disease giving an overall cure of 99%. Only 10 women (4%) experienced grade III/IV toxicity during the first course of treatment and 13 women (5.2%) subsequently. Toxicity included mucositis and stomatitis, pleuritic chest pain, thrombocytopenia, uterine bleeding, abdominal pain, liver function changes, rash and pericardial effusion. A total of 59 women (23.6%) required second-line chemotherapy; 48 women had methotrexate resistance, eight had methotrexate toxicity and an empirical decision to change therapy was made in three. In all, 11 women (4.4%) had a hysterectomy before, during or after treatment; 141 women (56.4%) became pregnant following treatment: in 128 (90.7%), the outcome was successful. Methotrexate with folinic acid rescue is an effective treatment for low-risk persistent trophoblastic disease. It has minimal severe toxicity, excellent cure rates and does not appear to affect fertility.

Still's disease is very rare in elderly patients. We report a case of Still's disease in an elderly patient that had an atypical initial presentation. A 76-year-old woman developed unexplained chronic anemia and thrombocytosis. Three years later she had acute onset of high fever, arthritis, maculopapular rash, pleuritic chest pain, abdominal pain, lymphadenopathy and elevated erythrocyte sedimentation rate. Rheumatoid factor and antinuclear antibodies were negative. She responded favorably to prednisone and methotrexate treatment. Anemia and thrombocytosis as well as Still's disease manifestations resolved.
