Job strain, social support in the workplace, and haemoglobin A1c in Japanese men.

Objectives: To examine the association between job strain (defined in the model of job demands and job control) and social support at the workplace with levels of glycosylated haemoglobin A1c (HbA1c)

Methods: All male employees aged 40-60 in a manufacturing firm, Japan, were invited to take part in the study. A blood sample was taken from the participants and HbA1c (%) was measured. Job strain and social support at the workplace were assessed with the job content questionnaire (JCQ).

Longevity, lifetime pig production and productivity, and age at first conception in a cohort of gilts observed over six years on commercial farms.

An observational cohort study was conducted using a producer group of 33 farms selected based on their completeness of reproduction data, including dates of birth, entry to a herd, and removal. Average lifetime pig production and parity at removal in a cohort of 2,265 females born in 1990 were 67.2 pigs born alive and 5.

[Rapid resolution of acute subdural hematoma; report of two cases].

We reported two cases of rapid resolution of acute subdural hematoma. Case 1, a 21-year-old female, sustained head trauma and became unconscious for about 15 min. Probably she was suffering from posttraumatic amnesia for about 1 day.

[A case of an cerebello-pontine angle pineoblastoma].

An extremely rare case of a left cerebello-pontine angle (CP angle) pineoblastoma has been reported. The patient was a 32-year-old male whose initial manifestations were those of increased intracranial pressure. CT scan showed a large enhancing mass located at the left CP angle, associated with a moderate occlusive hydrocephalus.

[DNA analysis of meningiomas using paraffin-embedded surgical specimens in connection with clinical recurrence].

Meningioma includes some clinically malignant cases which grow multifocally or recur rapidly. To develop methodology to distinguish clinically malignant cases, we examined the nuclear DNA of meningiomas by flow cytometry using paraffin-embedded specimens. 52 surgical specimens were studied from 52 cases of meningioma.

[Surgical indication to deep-seated arteriovenous malformation].

The natural history of cerebral arteriovenous malformation (AVN) is still a subject of dispute. In the case of deep seated AVM ruptures, the problem is more serious because the hemorrhages often give rise to severe disability or death, depending on their location. Total extirpation of the nidus is fundamentally the best choice for treatment of AVM.

[Malignant changes in a craniopharyngioma].

The authors report a rare case of a 10-year-old girl with craniopharyngioma which showed malignant change after the first operation and irradiation. In June 1981, the patient complained of headache, nausea and vomiting. CT revealed obstructive hydrocephalus due to the calcified mass lesion which extended to the third ventricle.

Ultrastructural and immunocytochemical characterization of polymorphonuclear leukocytes from gingival crevice in man.

Polymorphonuclear leukocytes from the gingival crevicular fluid (CF-PMNs) of patients with generalized severe periodontitis were examined using electron microscopy and immunocytochemical techniques. CF-PMNs were found to contain numerous phagocytic vacuoles. This suggests that CF-PMNs actively phagocytized various substances from the environment.
