Polygraphic evaluation of laughing and smiling in schizophrenic and depressive patients.

Polygraphic recordings was used to assess laughing and smiling, and results were compared for 34 normal controls, 24 schizophrenic patients, and 15 depressive patients. The schizophrenic and the depressive patients showed reduced "laughs of pleasure," i.e., laughing in reaction to a comic video assessed by laughing score; however, the depressive patients in remission showed the same laughing reaction as the controls. "Smiles as social signals" during interviews were reduced for the schizophrenic patients but remained for the depressive patients. There was a tendency for greater reduction of both laughing and smiling in disorganized- versus paranoid-type schizophrenia, suggesting that the disturbance of affect might be more severe in the former. These results show the possibility that polygraphic recording of laughing and smiling might be a useful method for investigating the disturbance of affect in schizophrenic and depressive patients.

Higher cerebral dysfunction in a case with atypical multiple sclerosis with concentric lesions.

A patient with atypical multiple sclerosis (MS) with clear concentric structure was studied using high field magnetic resonance imaging (MRI). This case was considered to be Baló's concentric sclerosis. Magnetic resonance imaging showed diffuse multiple concentric demyelinating lesions in the bilateral centrum semiovales, which finally regressed with the necrotic lesions remaining when the patient was discharged. During his clinical course, he showed some higher cerebral dysfunctions, such as memory disturbance, constructual apraxia and acalculia. He was treated with glycerin, prednisone and rehabilitation; all of which were effective in his recovery. Over a 4 month period, the patient recovered clinically, but some intellectual impairment remained.

Psychological stress in middle-aged and aged executives.

Neurotic symptoms were considered to be present in 21.9% of the 210 employees of a company following data analysis from a General Health Questionnaire (GHQ, 60 question items). The results in middle-aged and aged executives were compared. The total GHQ score was > or = 17 in 18/55 executives aged 40 years or above, but in only 9/60 non-executives controls was a significant difference observed (P < 0.05) between executives and non-executives. The scores for three subordinate scales, namely somatic symptoms, anxiety and insomnia, and social dysfunction, were higher in the executives than in the non-executives and showed a significant difference (P < 0.05) in the anxiety and insomnia scale. These results suggest that middle-aged and aged executives are more likely to have neurotic symptoms and more frequently to have anxiety and insomnia than their controls. We would like to apply this method to aid in the prevention, early detection and early management of stress.

[Chronic osteomyelitis of mandibulae].

As the human lower jaw (mandibula) itself is a hard bone, and when bacterial inflammation occurs in it by pericoronal infection of the 3rd molar or apical infection of caries tooth, the inflammation remains in the bone marrow and often progresses to acute osteomyelitis. The prominent sign of acute osteomyelitis in the lower jaw is mental nerve palsy which is the so-called Vincent's Syndrome. The causative organisms are not different from those of the common odontogenic infections. Recently, we have identified some strains of Oral Streptococci tolerant against PCs and Cefems and also ones capable of biofilm formation. When antimicrobial agents or drainage proves unsuccessful, acute osteomyelitis may become chronic, which is more difficult to treat. Surgical procedures, such as, debridement or decortication of cortex bone are necessary in most cases. If these surgical procedures do not give satisfactory result, the amputation of the jaw is not rare.
