A consecutive series of 44 patients with proven leptospirosis was studied to document the radiographic pulmonary abnormalities, assess their prevalence, correlate them with the clinical signs and symptoms and determine their prognostic significance. Abnormalities were found in ten patients (23%), this prevalence being less than previously noted. The abnormalities shown were non-segmental opacification (consolidation-eight cases), basal linear opacities (collapse-five cases) and pleural effusions (four cases). The first radiographic demonstration of a large pleural effusion in leptospirosis is recorded. Non-jaundiced patients had a higher prevalence (43%) of these abnormalities than jaundiced (13%). No other correlation with clinical signs or symptoms was found. The presence of these abnormalities had no prognostic significance. It is concluded that the presence of radiographic pulmonary abnormality in in-patients with leptospirosis is common. These abnormalities are non-specific and can mimic other diseases leading to diagnostic difficulty. Such abnormalities may be extensive in the absence of clinical signs and symptoms.
The need for urography following ascending pedal lymphography in malignant disease has been studied in 298 consecutive patients. Forty per cent of the urograms were abnormal. Urographic abnormalities due to the disease being investigated were heralded by abnormal lymphography except in four patients, three with carcinoma of the bladder and one with carcinoma of the cervix. The majority of abnormalities unrelated to the disease being investigated were of no significance. In a small number there was congenital malposition of the kidney so that it fell within the proposed field of treatment. It is concluded that it is unnecessary to do routine urography with every lymphogram. Indications for urography are abnormality or suspected abnormality of the lymphogram, failure to locate the kidneys on plain films and clinical indications such as carcinoma of the bladder or carcinoma of the cervix.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
