Acute upper airway obstruction--fiberoptic bronchoscopy in diagnosis and therapy.

Twenty-two patients were referred over a 3-year period for endoscopic evaluation of the upper airways. The diagnosis of acute upper airway obstruction was suspected from clinical means, and 8 of the 22 did prove to have critical encroachment of the upper airways requiring tube passage for stabilization. This technique utilizing the fiberoptic bronchoscope for diagnosis and tube placement represents the approach of choice in the adult population with acute upper airway obstruction.

Crisis intervention following severe psychological trauma in late pregnancy.

Following the violent death of a Lamaze group instructor, a team of three psychologists provided crisis intervention to the group members to help them deal with the sudden death. All of the women in the group were in the advanced stages of pregnancy at the time. The team constructed an environment of group and couple support, presented and encouraged specific cognitive discussion of the event, and helped develop a temporary safe community. During the intervention, group members were able to express their anger, fear, guilt, and anxieties caused by the death. Comments by group members and the new group leader over the following weeks indicate the intervention was successful.

Balloon dilation of iliac stenosis with distal arterial surgery.

Seven patients with concomitant atherosclerotic iliac stenosis and femoral artery occlusive disease were treated with polyvinyl balloon catheter dilation of the iliac artery and subsequent distal operative arterial reconstruction. The iliac lesions were short, localized, common and external iliac stenoses and the femoral lesions were superficial femoral artery occlusions in six patients and a common femoral occlusion in another. All seven iliac stenoses were successfully dilated. Subsequent operative femoral artery reconstruction was successful in these patients, with restoration of popliteal or pedal pulses and relief of ischemic symptoms over a follow-up period of two to 14 months. One patient's femoral popliteal bypass graft thrombosed four months postoperatively.

Legionnaires' disease: an atypical pneumonia.

Given the present state of the art, any case of apparent pneumonia that is not responding to optimum therapy, or of "viremia" which appears to be progressively deteriorating, should be considered Legionnaires' disease and treated accordingly until proven otherwise. Titers for antibody to the disease in serum obtained during the acute and convalescent stages should always be determined in such cases. This may initially prove to be a rather wasteful and expensive procedure. However, only by carefully studying these titers can the elusive course of the disease be better delineated and techniques perfected that may allow earlier diagnosis and thus reduction in mortality.

Pulmonary thromboembolism. 1. Current concepts in pathogenesis and diagnosis.

Thrombosis results from the dynamic interaction of venous stasis, hypercoagulability, and endothelial injury. Protection against thrombosis may be lost if there is deficiency of any of the factors that mediate platelet deaggregation, block fibrin deposition, or initiate fibrinolysis. A thrombus lodged in the pulmonary arterial circulation may remain hemodynamically and clinically silent or produce hemodynamic, clinical, and radiographic alterations. Although no signs and symptoms are specific to the condition, pulmonary thromboembolism can be diagnosed clinically if predisposing factors are taken into consideration. Diagnostic procedures include contrast venography, right heart catheterization, ventilation/perfusion lung scanning, and pulmonary angiography.

Gastric polyps on routine double-contrast examination of the stomach.

Gastric polyps were found in 38 patients in a series of 2,420 consecutive double-contrast studies of the upper gastrointestinal tract. The resulting incidence of 1.6% is four times the highest figure previously reported. Single polyps were usually located in the antrum, multiple polyps in the body of fundus. Two-thirds were less than or equal to 10 mm in diameter; only one was larger than 20 mm. Endoscopy was performed in 17 cases and showed either normal or inflamed gastric mucosa with no evidence of neoplasia. It is likely that most gastric polyps are inflammatory or hyperplastic, while the biopsies showing normal mucosa may represent small submucosal tumors such as leiomyomas. This study demonstrates the high frequency and innocuous nature of small gastric polyps.

The deep sulcus sign.

On a supine chest radiograph, the only sign of pneumothorax may be a deep lateral costophrenic angle on the involved side. Seven cases where this finding was present are reviewed and the importance of this sign to radiologists and clinicians is stressed.

Ego development and sociometrically evaluated maturity: an investigation of the validity of the Washington University Sentence Completion Test of Ego Development.

The reported study was an attempt to validate the Washington University Sentence Completion Test of Ego Development (WU-SCT), using a broad, sociometric index of maturity as the criterion variable. Sixty college women living in a sorority house completed the WU-SCT and evaluated one another's readiness for mature functioning in each of four adult social roles: career, marriage, parenthood, and community involvement. The reliabilities and the intercorrelations of the ratings suggested that peers distinguished two facets of maturity. While results support the hypothesized relationship between WU-SCT scores and a global sociometric index of maturity, the test's substantial correlations with indices relating to relatively impersonal roles (career and community) and apparent lack of correlation with indices relating to intimate interpersonal roles (marital and parental) suggests that the validity of the WU-SCT may be less broad than Loevinger's theory would imply. Several alternative interpretations of the data are suggested.

Endobronchial lipoma causing unilateral absence of pulmonary perfusion.

Endobronchial lipoma is a slowly growing benign neoplasm of the large bronchi, which, if left untreated, has a significant morbidity and mortality. Endobronchial lipoma is still rare, with only 50 reported cases in the English literature, including the following case. This case illustrates the sequela of main-stem occlusion of the airway due to this tumor and, to our knowledge, represents the first reported case of unilateral absence of pulmonary perfusion due to an endobronchial lipoma. Proposed mechanisms for unilateral absence of perfusion due to an endobronchial lipoma are discussed.

Effect of sampling site and conditions on plasma levels of noradrenaline, adrenaline and dopamine.

Levels of noradrenaline, adrenaline and dopamine were measured simultaneously from different sites, during stimulation and during noradrenaline infusion. Levels of the three catecholamines were similar in low inferior vena cava and a forearm vein. The ratio between adrenal venous and peripheral levels averaged 49:1 for adrenaline but only 4:1 for noradrenaline, consistent with other significant sources for noradrenaline apart from the adrenal. Levels of dopamine were only slightly higher in adrenal venous blood, consistent with the adrenal being a minor source in these subjects. Forearm arteriovenous differences for adrenaline and noradrenaline demonstrated significant removal of these amines across this vascular bed. To monitor sympathetic responses, venous noradrenaline appears satisfactory, but venous adrenaline would miss responses detected by arterial levels. Sympathetic responses were not reflected by changes in either arterial or venous dopamine.
