SynopsisThis study compared clinically depressed subjects with normal controls on a range of working memory tasks. The findings suggested the articulatory loop and visuospatial sketch pad components of working memory to be unimpaired in depression. On a range of clinical tasks likely to involve central executive function, depressed subjects showed impairment only on some tasks.

Sclerosis of the mastoid portion of the temporal bone is often seen on radiographs of patients who have or have had chronic otitis media. Occasionally lesions are seen that cause sclerosis of the entire temporal bone. The otolaryngologist must be alert to the fact that these findings may signify important pathology beyond that of chronic otitis media and indeed may be indicative of life threatening problems in adjacent or distant areas. In this paper the differential diagnoses of sclerotic lesions of the temporal bone will be discussed. These include fibrous dysplasia, osteopetrosis, meningioma, ossifying fibroma and metastatic lesions to the temporal bone. Three representative cases with sclerotic temporal bones are presented. The first is a patient with a conductive hearing loss secondary to stenosis of the external auditory canal. He was found to have a fibrous dysplasia of the temporal bone. The second case is an elderly male with a draining ear and a facial nerve paresis. He was found to have adenocarcinoma of the prostate gland metastatic to the temporal bone. The third case is that of a woman with a meningioma who demonstrated a sclerotic temporal bone on routine radiographs of the skull.

The present study compared retrieval of high, medium, and low structured material, using word lists consisting of uncategorized words and categorized words presented in randomized and clustered order. Clinically depressed subjects were found to be significantly impaired relative to controls only on the medium level of structure and the randomized categories list when measured by free recall. There were no effects of group nor any interactions for recognition memory, although there was a main effect for group on d' when signal detection analysis was applied. The implications of the findings for models of memory deficits in depression are discussed.

We compared temporal lobe epilepsy (TLE) outpatients attending a general hospital with depressed psychiatric patients and normal control subjects to investigate depressive symptomatology. Both clinician-rated measures and self-report questionnaires were used. Rates of depressive and anxious symptomatology in TLE subjects were higher than those in a normal control sample, but TLE subjects did not differ significantly from controls on anxiety measures. The depressed psychiatric group scored higher than the TLE and control groups on both depression and anxiety measures. Rates of depressive symptomatology in the TLE group were lower than those reported in previous studies for persons attending specialist epilepsy clinics, but similar to the findings of one community study.
