This case report describes a 20-year-old woman who developed acute group B streptococcal endocarditis after a saline-induced abortion. She was admitted 2 weeks after an uncomplicated saline-induced abortion for a 16-week pregnancy with a 1-week history of fever, headaches, dizziness, and shortness of breath. The patient showed poor response to antibiotic therapies (initially to nafcillin and gentamicin and then to aqueous penicillin G). 6 to 6 blood cultures after hospital admission showed group B streptococcus which was penicillin sensitive by tetracycline resistant. On Day 3 of admission, a pericardial friction rub was noted and repeat chest x-rays showed marked enlargement of the cardiac shadow. Surgery was performed, and the mitral valve posterior leaflet was necrotic, and a mitral valve prosthesis was placed and an aortic embolectomy was performed. Postoperatively, she was treated with an additional 6-week course of intravenous penicillin, and subsequently, she has remained asymptomatic after 6 months. An addendum to this report, which was only the 2nd such report of endocarditis after saline abortion, describes another case of group B streptococcal endocarditis in a drug abuser after a saline-induced abortion. She required tricuspid valvulectomy and is slowly improving postoperatively.

A patient experienced episodic pulmonary edema accompanying nocturnal angina pectoris. The symptoms were provoked at cardiac catheterization by atrial pacing. Simultaneous onset of chest pain, shortness of breath, and sudden appearance of a large V wave in the pulmonary artery wedge pressure contour confirmed acute mitral valve regurgitation. Rapid reversal of these changes after nitroglycerin administration supported "papillary muscle dysfunction" as the explanation for these hemodynamic changes.

The mechanism of prostaglandin F2 alpha(PGF2alpha)-induced airway constriction was explored by determining the influence of atropine and cromolyn on the bronchoconstrictive properties of PGF2alpha. Increasing doses of aerosolized PGF2alpha were given (150, 300, 600, 1200 microgram) and the response of subjects was determined by measurements of spirometry, specific airway conductance (SGaw), and closing volumes. In normal subjects, PGF2alpha induced small but significant decreases of SGaw and spirometric parameters (FVC, FEV1), whereas there was no effect on the closing volumes. In contrast, in asthmatics, PGF2 alpha induced large decreases of SGaw and spirometric parameters. Asthmatics experienced severe and prolonged shortness of breath and wheezing, whereas normal controls experienced neither. Neither atropine nor atropine plus cromolyn was capable of preventing or substantially reversing the PGF2alpha-induced symptoms and airway constriction. The data suggest that reflex bronchoconstriction via irritant receptors is not a major mechanism of PGF2alpha-induced airway constriction. Although a minor vagally mediated reflex component may participate in the PGF2alpha-induced bronchoconstriction, it is masked by an overwhelming non-reflex mechanism that is probably a direct constricting effect of airways smooth muscle that is exquisitely sensitive to PGF2alpha.

During the last 12 years, 30 cases of tracheopathia chondro-osteoplastica have been diagnosed at the Department of Otolaryngology of Kuopio University. Ten of these were accidentally revealed by bronchoscopy, 2 by autopsy, but 18 were revealed through a systematic examination. Ten of these 18 were preliminarily diagnosed by indirect laryngoscopy. The average age for women was 51 and for men 42, the youngest patient being 11 and the oldest 71 years of age. The characteristic symptoms were long-term recurrent cough, hoarseness and periodic expectoration. The sputum was frequently abundant and crusty, and sometimes contained streaks of blood. Shortness of breath was a common symptom, but there were often entirely asymptomatic periods. The disease begins with a persistent purulent tracheitis, which, probably owing to calciphylaxis, causes accumulation of calcium salts in the tracheal mucosa. Cartilage and bone later develop around these accumulations. In most of the cases of tracheopathia chondro-osteoplastica in the present series, the condition was associated with atrophic rhinitis or pharyngitis. As the nasal disease improves, some regression may occur, though hardly healing. Calcium and phosphorus metabolism was not disturbed, and no immunological aberrations were found in any of the patients in this series.

Mediastinal extension of pancreatic pseudocysts is uncommon. Frequent presenting complaints include chest pain and shortness of breath. Dysphagia is rare. A patient with mediastinal pseudocyst causing dysphagia is presented. The role of gray-scale ultrasound as a reliable means of diagnosis is discussed.

A 47-year-old man experienced palpitations and shortness of breath following push-up exercises. Because of paroxysmal atrial fibrillation and fatigue, the patient underwent investigation. Echocardiography and cardiac catheterization indicated the diagnoses of mitral valve prolapse and rupture of the chordae tendineae. This report represents the first description of such a sequence of events.

A 32-year-old woman with a one-year history of progressive shortness of breath and chest pain was found to have a grade 4/6 systolic murmur at the base of the heart and left sternal border. Right ventricular enlargement was found by physical examination, ECG, and chest roentgenogram. Cardiac catheterization showed elevated right ventricular pressure, an intracavitary pressure gradient, and inability to enter the pulmonary artery. Angiography revealed a mass in the right ventricular outflow tract. Successful surgical removal of a large, well-encapsulated tumor mass was accomplished, and the tumor was interpreted as a benign neurilemoma. Postoperatively, the patient improved remarkably.

Pertinent historical, clinical, and laboratory findings were recorded for 37 consecutive patients who presented to the emergency room complaining of shortness of breath and chest pain but without evidence of coronary insufficiency, pneumonia, or musculoskeletal injury. 13 had pulmonary embolism suggested by lung scan with or without pulmonary angiogram, or, in 2 cases, by right heart catheterization. As a group, these patients in whom embolism was judged probable approached fairly closely the profiles of previous studies of patients with documented pulmonary emboli. Nonetheless, they differed very little, and in no clinically useful way short of lung scans and invasive studies, from the remaining 24 patients in whom embolism was judged unlikely. In the population served by this emergency room, which has a high morbidity from chest diseases and putative predisposing conditions to pulmonary embolism, screening patients for high and low probability groups for this diagnosis cannot be done on clinical grounds alone. Six-projection ventilation-perfusion lung scanning may be the only acceptable screening examination, and should be available directly from the emergency room in hospitals with an active emergency service.

A 20 year old black man presented with shortness of breath, hilar adenopathy, monoarticular arthritis, polydipsia and polyuria, and bilateral testicular masses. Transbronchial biopsy revealed noncaseating granulomas consistent with sarcoidosis. Subsequent work-up demonstrated hypothalamic dysfunction, and joint fluid analysis was consistent with sarcoid arthropathy. Concern over the possibility of a testicular neoplasm led to right testicular biopsy which revealed noncaseating granulomas consistent with testicular sarcoidosis. A short course of steroid therapy resulted in clinical improvement and complete resolution of the remaining left testicular mass.

We have successfully treated two patients with symptomatic pneumatosis cystoides intestinalis using a high FIO2 delivered by face mask, with administration interrupted at meal times. While we advocate oxygen therapy for this disease, caution must be taken to avoid the complications of high PaO2, namely proliferative and fibrotic lung changes. Close attention should be paid to the development of increasing cough, dyspnea and shortness of breath. As the frequency of the diagnosis of pneumatosis cystoides intestinalis increases, the success of high inspired oxygen as therapy should be recognized.
