Vancomycin-intermediate Staphylococcus aureus in a home health-care patient.

In June 2000, vancomycin-intermediate Staphylococcus aureus (VISA) was isolated from a 27-year-old home health-care patient following a complicated cholecystectomy. Two VISA strains were identified with identical MICs to all antimicrobials tested except oxacillin and with closely related pulsed-field gel electrophoresis types. The patient was treated successfully with antimicrobial therapy, biliary drainage, and reconstruction. Standard precautions in the home health setting appear successful in preventing transmission.

Access to health care: rhetoric vs. reality.

This article has attempted to provide a broad stroke overview of some of the populations who are effectively denied adequate or any access to health care in our country. As there are multiple barriers to access, as illustrated earlier, so too social workers and discharge planners must be cognizant of the various ways that they can provide entree to health care for those who are disenfranchised. In a succeeding article, we will explore avenues for individual advocacy as well as for systematic change in the delivery system that can be effectuated by social workers and discharge planners.

Chest radiograph changes after cardiopulmonary bypass in children.

To determine the spectrum of pediatric chest radiograph changes after cardiopulmonary bypass, 98 children (mean age = 5.9 yr, range 4 wk-16 yr) were studied for 3 days postoperatively. Daily A-P radiographs were evaluated for atelectasis, cardiomegaly, pleural effusions, diaphragmatic elevation, mediastinal widening, and pulmonary infiltrates. The overall incidence of atelectasis was 82%, with left lower lobe atelectasis the most common (64%). Right upper lobe atelectasis occurred in 35% of patients, far more common than in the adult. Radiographic changes were then compared with independent variables including patient weight, age, duration of bypass, and fluid balance by multiple linear regression. Pleural effusion correlated with patient weight and duration of bypass. Diaphragmatic elevation correlated with patient weight. Cardiomegaly correlated with patient age. Net fluid balance was a poor predictor of postoperative chest radiograph changes. We conclude that radiographic changes are common after cardiopulmonary bypass in children, that the overall incidence is not markedly different from adults, and that right upper lobe atelectasis occurs more frequently in children.

Limitations of esophageal electrocardiography in recording atrial rhythms after orthotopic heart transplantation.

Esophageal electrocardiography is a commonly used tool for the differential diagnosis of arrhythmias. A 39-year-old man who underwent orthotopic heart transplantation developed a narrow complex tachycardia. Esophageal electrocardiography showed a junctional tachycardia (recording native atrial activity alone), whereas atrial intracavitary electrograms showed the correct diagnosis of atrial flutter. Esophageal recording in patients who undergo orthotopic heart transplantation is a useful technique for recording native atrial activity. For arrhythmia diagnosis in these patients it is frequently necessary to record donor atrial activity with intracavitary electrograms. The limitations of esophageal electrocardiography should be recognized by physicians who care for these patients.

Magnetic resonance imaging techniques in children.

A method of scanning children using magnetic resonance imaging (MRI) is described. Besides detailing ways to keep the patient comfortable and relaxed, which also allows for better resolution, the authors point out the necessity to plan objectives before beginning the MRI study.

[Abnormal gas collections in the abdomen in infants].

Many unusual and uncommon abnormal gas collections within the abdomen may be encountered. This paper reviews the reported causes for unusual gas collections in the abdomen and describes several new causes of abnormal bowel gas collections.

Facial swelling and giant cell arteritis.

A 62-year-old white woman presented with severe facial swelling, glossitis, and odynophagia. Giant cell arteritis (GCA) was diagnosed on the basis of temporal artery biopsy, and the patient responded to corticosteroids. GCA may rarely involve vessels of the mouth and face, resulting in unusual clinical manifestations. Early recognition and treatment are important.
