Abstract: Five cases of clinically manifest solitary and bilateral renal lesions metastatic from the lung are presented. These cases are unusual in that renal metastases are usually silent lesions discovered at autopsy. Review of the autopsy data from this hospital identified renal metastases in 19% of patients who died from carcinoma of the lung. This incidence parallels that of other series. A solid renal lesion which is identified in a patient with a history of pulmonary carcinoma should raise the suspicion of renal metastases, especially if computed tomography of the mass demonstrates relative homogeneity and minimal enhancement. More frequent use of the abdominal CT scan in staging patients with lung cancer will render metastatic carcinoma from lung to kidney a more frequent ante mortem diagnosis.
Which is the apt title for the abstract? option1: Renal metastases from carcinoma of the lung. option2: The effects of combined H1 and H2 histamine antagonists on alterations in nasal airflow resistance induced by topical histamine provocation.
answer:
Renal metastases from carcinoma of the lung.

Abstract: An analysis was completed of 34 patients with dementia who attended a mixed medical day care program over a five-year period. The parameters reviewed included age, home situation, diagnosis, incidence of co-existent medical disorders, management by the social worker, nurses and neuropsychiatrist, the extent of social and program participation, length of stay, and disposition. There was a high incidence of medical problems which were managed effectively because of close nursing observation, availability of ancillary services, specialty clinics, and frequent communication with the community physicians. The social worker assisted families with the management of long-term planning for the dementia patients and the entire social-nursing-recreational therapy team devised programs which encouraged the patients to function at an optimum level. Neuropsychiatric management, including drug therapy, was an integral part of the program. Despite the fact that the dementia patients were at high risk, with an average age of 81 years the average duration of attendance was two years four months and only nine of the 34 patients ultimately required nursing home placement. It was concluded that the day care program served as a resource which devised, integrated, and supervised, in cooperation with the community physicians, the support network and management strategies for the dementia patients.
Which is the apt title for the abstract? option1: Treatment of dementia in a medical day care program. option2: Fire without smoke [news]

Abstract: Spastic patients were instructed to make accurate, rapid ankle dorsiflexion and plantarflexion movements over different distances to a target. Ankle position and surface electromyograms (EMGs) from tibialis anterior (TA) and soleus (SOL) muscles were recorded. In 3 of 8 spastic patients tested, dorsiflexion evoked velocity-dependent activation of the antagonist (SOL) muscle which impeded the movement to the extent that the limb unintentionally reversed movement direction. We propose that this activation is reflex in origin since it is tightly synchronized, has a large peak amplitude, occurs about 50 ms after the initiation of the movement, and is velocity dependent. One of the 3 patients who had reflex-induced antagonist activation in dorsiflexion also demonstrated sustained clonus during plantarflexion. This usually occurred only if the target had been overshot so that the return of the limb stretched the soleus muscle and triggered clonus. We conclude that in some patients, hyperactive stretch reflexes cause movement deficits.
Which is the apt title for the abstract? option1: Movement deficits caused by hyperexcitable stretch reflexes in spastic humans. option2: Perinatal-maternal relationships in the regulation of IgE antibody responsiveness.
answer:
Movement deficits caused by hyperexcitable stretch reflexes in spastic humans.
