Dental visits, teeth remaining, and prosthetic appliances in a Norwegian urban population.

Of a random sample (177 persons) of 35-year-old Oslo citizens, 117 subjects (66.1%) attended a dental examination. Questionnaires were returned by mail from 28 of the non-respondents. The most common reason for not attending was "difficulty in finding time for an appointment." About 89% of the respondents had visited a dentist regularly. Regular dental care seemed to be more common among people with a high level of education than among those with a low level of education. The most common treatment performed at the last dental visit was filling of cavities. The mean number of remaining teeth was 25.7. Females in the lower educational group had significantly less teeth than those in the higher educational group. No subjects were totally edentulous, but five persons had one edentulous jaw. Nine full or partial dentures were found. Twelve percent of the subjects had one or more fixed bridges, and 29.9% of the persons had one or more crown restorations. There seemed to be no differences between the sexes or educational levels in this respect.

Axial skeleton and pituitary gland in human fetuses with spina bifida and cranial encephalocele.

The purpose of this study was to investigate the axial skeleton and the pituitary gland in fetuses with spina bifida or cranial encephalocele in order to elucidate the pathogenesis of the conditions. The findings were related to former investigations performed on normal fetuses and on fetuses with anencephaly and rachischisis. Eight human fetuses from spontaneous or therapeutic abortions, 11-28 weeks of gestational age, were investigated. Radiographs were taken of the axial skeleton and histological investigation, including immunohistochemical marking for thyroid-stimulating hormone was performed on tissue blocks of the cranial base, including the sella turcica and the pituitary gland. Radiography revealed only minor malformations in the axial skeleton and not in all cases. The types of malformations resembled those seen in anencephaly and rachischisis. Histological investigations revealed severe malformations in the sella turcica region in spina bifida and minor ones in cranial encephalocele. Pharyngeally located adenopituitary gland tissue occurred in all fetuses. Anencephaly and cranial encephalocele seemingly are conditions resulting from different expressivity of the same multifactorial process of maldevelopment involving mesoderm (skeleton), neurectoderm (spinal cord and brain), and surface ectoderm (adenopituitary gland tissue). It is suggested that the molecular biological signaling between the notochord, the scleroderm, and the surface ectoderm is disturbed in spina bifida and cranial encephalocele.

Isolated valvular aortic stenosis. Clinico-pathological findings in an autopsy material of elderly patients.

In a review of 2557 autopsy reports from a general hospital 20 patients, aged 65 or above, have been found to have severe isolated valvular aortic stenosis. The diagnosis was made or suggested clinically in only 5 cases. The clinical findings were often atypical, e.g. the BP amplitude was above 50 mmHg in 9 patients and 4 had a systolic BP of 180 mmHg or more. Left ventricular hypertrophy as evaluated by ECG was, however, present in all examined cases but one. The main cause of death was cardiac in 17 cases, of whom 2 died suddenly and 4 following non-cardiac surgery. At autopsy significant coronary arteriosclerosis was found in all but 2 patients. In 9 patients acute myocardial infarction was demonstrated--in 2 cases only through a macroscopic enzyme test (Nitro-BT method).

Postmortem axial skeletal radiography can reveal fetal CNS malformations.

The routinely performed autopsy of a macerated fetus will often be of dubious value, particularly as regards the examination of the central nervous system (CNS). Former studies have demonstrated a close relationship between certain CNS malformations and axial skeletal malformations revealed radiographically. In the present report a postmortem examination of a severely macerated fetus demonstrates a transsphenoidal encephalocele. A supplementary histological examination confirmed this condition and furthermore revealed absence of the pituitary gland. The findings were related to a strongly elevated serum alphafetoprotein level in the 18th gestational week. This report emphasizes the value of postmortem axial skeletal radiography of autolyzed fetuses suspected for CNS malformations.
