Antral washout with nasal polypectomy: should both be combined?

Two hundred and sixteen patients with nasal polyps were studied. All patients had antral washouts performed at the same time as nasal polypectomy. Two hundred and sixty aspirates were sent for culture and microscopy; bacteria were cultured from 58 of these specimens in 38 patients. One hundred and one patients had pre-operative sinus radiographs of which 94 were reported as abnormal with a 52% false-positive result. It is concluded that antral washouts should be routine in all patients having nasal polypectomy. Sinus radiographs are an unnecessary pre-operative investigation in patients with uncomplicated nasal polyps.

Nasal polypectomy: should antral washout be a routine?

Seventy patients with nasal polyps were studied. Forty-seven of these had pre-operative sinus radiographs and all seventy patients had antral washouts at the time of nasal polypectomy. One hundred and seventeen antral aspirates were sent for culture and microscopy. The naked eye appearance of aspirates were turbid in 34 patients. Bacteria were cultured from 15 of the specimens in 10 patients. It was concluded that antral washout should be recommended in all patients who have nasal polypectomy and that there is no need for sinus radiographs in those patients who have uncomplicated nasal polyps.

Unusual manifestations of pneumococcal infection in human immunodeficiency virus-infected individuals: the past revisited.

Although AIDS was largely recognized and defined because of the increased presence of diseases that reflect deficiencies in cell-mediated immunity, susceptibility to common extracellular bacterial pathogens has also been shown to be increased. To our knowledge, adults with concurrent infection due to human immunodeficiency virus (HIV) and Streptococcus pneumoniae whose cases have been described to date have all had pneumococcal pneumonia and/or bacteremia. We describe five cases of HIV-infected patients who had unusual manifestations of pneumococcal infection, which include recurrent exudative pleural effusion, pyopneumothorax, purpura fulminans, mediastinitis with chest wall abscess, and multiple brain abscesses. Such complications of pneumococcal infection occurred more or less commonly in the preantibiotic era, but on the basis of our experience and an exhaustive literature search, these complications have been exceedingly rare in the past few decades. In four of our five patients, the unusual, complicated pneumococcal disease preceded and prompted a search for HIV infection. Because concurrent HIV infection increases the susceptibility to pneumococcal disease, other such cases are likely to be seen.

Postoperative respiratory failure secondary to Pneumocystis carinii pneumonia.

Pneumocystis carinii pneumonia (PCP) occurs frequently in individuals infected with the HIV virus. Malignancy, immunosuppressive drugs, and congenital immune deficiency may be associated with PCP. We describe a patient with stage 1 testicular carcinoma who developed hypoxemic respiratory failure two days after retroperitoneal lymph node dissection. Pneumocystis carinii organisms were demonstrated by catheter lavage samples and confirmed on bronchoalveolar lavage. Testing for HIV antibody by ELISA and the Western blot test were negative; HIV viral culture and polymerase chain reaction were also negative. Pneumocystis carinii pneumonia is unusual in localized surgically cured malignancies without obvious immunodeficiency and, to our knowledge, has not been described as a cause of postoperative respiratory failure.

Sexual harassment in academia: legal and administrative challenges.

Guidelines and institutional policies regarding sexual harassment in academia have a relatively short and controversial background. Deference to Equal Employment Opportunity Commission (EEOC) guidelines in employment sexual harassment incidents guides much of the thinking in contemporary courts. Title IX of the Educational Amendments and the Civil Rights Restoration Act of 1987 are but two of the legal redresses available to students with harassment grievance complaints. Lack of definition of the term as well as research studies in nursing complicate the issue of sexual harassment. The potential impact of harassment on nursing students both in the classroom and in the practice area is significant. Nursing administrators and educators must be proactive in writing and implementing policies regarding sexual harassment.
