Isolation needs and control of infection in NZ hospitals.

The purpose of this paper is to discuss infections in New Zealand hospitals under two headings: 1. Isolation needs. 2. Control of infection as it pertains to prophylaxis. An assessment of modern needs in terms of numbers of isolation beds is made on the basis of present-day infections. Brief reference is made to the epidemiology of hospital infections and to the principles of isolation according to categories of infection -- the Card System -- and to specification of the facilities required. The importance of a Control of Infection Nurse is emphasised and suggested members of a Control of Infection committee are enumerated. The proposed methods for preventing and dealing with infections apply particularly to base hospitals. It is hoped however that the principles enunciated are sufficiently obvious that they can be readily adapted to smaller community hospitals. It is concluded that all New Zealand hospitals should have a formal control of infections system instituted.

Pulmonary blastoma: cytopathologic and histopathologic findings.

A case of pulmonary blastoma has been presented with a description of the pulmonary cytology and review of the literature. Recognition of the two cell patterns of the tumor, carcinomatous and sarcomatous elements, in the cytologic specimen may lead one to the correct diagnosis of a mixed tumor. Ferruginous bodies and microliths were also associated in this case.

Positive effusion cytology as the initial presentation of malignancy.

During a period of four years (1981 to 1984), 641 ascitic, 860 pleural and 47 pericardial fluid specimens were examined cytologically. Of these, 154 ascitic samples, 174 pleural specimens and 10 pericardial effusions, obtained, respectively, from 108, 133 and 7 patients, were found to contain malignant cells. In 7 patients, ascites, and in 18 cases, pleural effusions were the first indication of cancer. None of the positive pericardial fluids was the initial presentation of malignancy. The cytologic findings and follow-up data on these 25 patients are the subject of this study. The most common type of neoplasm in these effusions was adenocarcinoma (86% of the ascitic and 78% of the pleural fluids). Most of the malignant neoplasms in ascitic fluids were derived from ovarian tumors (5 of 7) while those in pleural effusions came mainly from lung tumors (12 of 18). Mammary carcinoma, which was the most common malignant tumor found in cases of pleural effusions, did not present initially with an effusion in any of our cases. The cytologic diagnosis was confirmed in all cases by either biopsy or strong clinical evidence. The prognosis in patients who initially presented with an effusion was poor. All of the patients with an adequate follow-up died within 29 months in cases of ascites and within 19 months in cases of pleural effusions.

Diagnostic pitfalls in cerebrospinal fluid cytology.

Four types of cells that may be the source of important diagnostic pitfalls in cerebrospinal fluid cytology are presented: (1) nucleus pulposus cells, (2) keratinized squamous cells from craniopharyngioma and sphenoid sinus carcinoma, (3) reactive leptomeningeal cells and (4) epitheloid cells from sarcoidosis. For each the cellular morphology is described and representative clinical, cytologic and histologic presentations are discussed.
