Preoperative histological or cytological confirmation of a diagnosis of bronchogenic carcinoma is not always possible, so occasionally non-neoplastic lesions are resected. Of these lesions a significant number are described by pathologists as 'unresolved pneumonia'. We studied the case notes and histopathology of 30 patients from whom lung had been resected and which had been classified as pneu...

OBJECTIVE To retrospectively analyse causes of childhood proptosis and their investigations and treatment. METHODOLOGY The records of children under 15 years of age presenting with proptosis to The Children's Hospital, Camperdown, Sydney, were reviewed for the period 1983-93 inclusive. RESULTS Fifty-seven cases of proptosis were found. In order of frequency the causes were; orbital cellulit...

In spite of continued research the pathogenesis of rheumatic fever remains a problem of much complexity. In the pursuit of its aetiology during the past 60 years, intensive bacteriological studies have been carried out, metabolic disturbances have been considered, allergic mechanisms have been incriminated, the role of heredity, dietary deficiency and a host of other factors have been investiga...

The natural history of asthma involves relatively stable periods that are often punctuated by significant exacerbations of symptoms. There are many aetiologies that may lead to an increase in asthma severity including respiratory infection (bacterial/viral), allergens, irritants, and occupational exposures. Each trigger probably acts through different mechanisms, but a final common pathway of m...

Pleural plaques were found in 644 (66%Y.) of 9,760 photofluorograms taken in 1965 in a region of Pel'hrimov district; the incidence was highest in the age group 66-70 years. The advanced age of those affected may be explained by the greater frequency of the causative agent in the past. The disorder was known in Pelhrimov district as early as 1930; it was then thought to be posttuberculous. The ...

Although clinicians are preoccupied with treating myopia and its complications, the causation is worth our attention, and particularly the results of experiments on animals in recent years. These have some implications for the treatment of patients. Myopia's remarkable bilateral symmetry suggests a hereditary basis. This is supported by Sorsby's observation' that 78 pairs of identical twins sho...

Thirteen serum samples from nine children with Kawasaki disease and 23 control samples gave negative results on screening for antibodies to hog cholera virus, border disease of sheep, bovine diarrhoea virus, and equine arteritis virus. The sera from two children with Kawasaki disease were cytotoxic; a possible link with cytotoxin from Propionibacterium acnes is considered.

These 2 cases provide additional examples of HUS occurring in sibs after a long interval. The family resided in New York City, which is not considered as an endemic area for HUS, and the clinical course of the disease in both infants was almost identical, culminating in early death. The aetiology of HUS may indeed be multiple, and the genetic basis for a significant proportion of cases does not...

This paper will introduce the ‘Psych-Aetiology Graph’, PAG for short. The concept of PAG is devised by the author as a way of conceptualising/formalising/summarising the client’s condition. The term ‘Psych-Aetiology’ is used to encompass all the Bio-Psycho-Social factors contributing to the client’s presenting condition. Also, the graph has no arithmetic value and is not based on any particular...
