Abdominal pain in a 70-year-old Danish population. An epidemiological study of the prevalence and importance of abdominal pain.

In order to assess the prevalence and importance of abdominal pain in the elderly, an epidemiological study of a 70-year-old Danish population was carried out. Seventy two percent of 1119 randomly selected persons answered a questionnaire concerning abdominal pain. One year prevalence of abdominal pain was 28% among women and 17% among men (p < 0.01). Among those with abdominal pain no significant sex difference was found as regards location, severity, frequency, or medicine consumption. Eleven percent of the men and 19% of the women had abdominal pain which they considered to be of importance to their well-being in terms of frequency, severity, or need of medicine (sex difference: chi 2 = 10.18, df = 2, p < 0.01). Participants who had no abdominal pain judged their general health to be better than those who had experienced abdominal pain (p < 0.01). It is concluded that abdominal pain is frequent in a 70 year old population and influences the well-being of the subjects. Further studies are needed to evaluate whether subjects with abdominal pain have a poorer prognosis than subjects without.

The role of the flow rate of the pneumohydraulic system on post-sphincter of Oddi manometry pancreatitis.

Manometry of sphincter of Oddi (SO) carries a risk of acute pancreatitis by a mechanism not yet clearly understood. This study attempted to evaluate the role of the flow rate of the perfusion system in the development of acute pancreatitis. During the past 60 months, we have performed 81 manometry studies of SO in 79 patients, 61 women and 18 men, who were referred for recurrent attacks of abdominal pain suggestive of SO dysfunction. All procedures were done by the same operator, utilizing the same instrumentation and similar premedication. In the first 54 studies, the pneumohydraulic system had a flow rate of 0.55 ml/min and a tank pressure of 15 lb/in2 while in the last 27 studies a flow rate of 0.27 ml/min and a pressure of 7.5 lb/in2 were employed. Acute pancreatitis was diagnosed after 16 (19.7%) procedures. Fourteen (26%) of them occurred after high-flow-rate perfusion. In contrast, only 2 (7%) of the 27 patients who had the procedure done at the flow rate developed this complication (p less than 0.05). There was no correlation between the occurrence of pancreatitis, clinical suspicion of SO dysfunction, and the underlying manometric profile of the sphincter. We conclude that the incidence of procedure-related pancreatitis after manometry of SO is higher than following diagnostic endoscopic retrograde cholangiopancreatography and that the flow rate in the perfusion system is a precipitating factor in the development of this complication.

[Recovery after ambulatory vasectomy].

The recovery after outpatient vasectomy, with particular attention to general postoperative complaints, was investigated by means of a questionnaire. A material of 115 patients who were submitted to operation during the period 1.1.1988-31.12.1988 was covered by the investigation. Replies were obtained from 81%. The frequency of complaints/complications apart from the first 24 hours postoperatively was found to be unexpectedly high as 77% had from one to seven complaints/complications (average 2.8), pain and swelling being the commonest. 32% had complaints for three weeks or more while 90% were free from complaints after nine weeks. The secondary consequences of the complaints were apparent inconsiderable preoperative illness and a great number of postoperative contacts with the general practitioner. 23% had sick-leave for more than the first 24 hours postoperatively, 6% for more than one week and a total of 47 contacts with the practitioner occurred in 82 men. It is recommended that thorough information about the postoperative course should be provided by the departments in order to reduce the number of days of postoperative sick-leave and the number of contacts with the health services.

The epidemiology of gallstones in a 70-year-old Danish population.

A random sample of 540 men and women aged 70 years who lived in the western part of Copenhagen County was drawn from the National Central Person Register. The response rate was 74.8% among men and 63.7% among women. Each subject had the gallbladder examined by ultrasonography. The prevalence of gallstone disease was 30.2% and 18.8% among women and men, respectively, being significantly higher among women. Prevalence was assessed in relation to different social and clinical variables. In the univariate analyses gallstone disease was significantly associated with familial occurrence of gallstone disease and high body mass index, whereas it was not significantly associated with social status, childbirths, age at menopause, usage of menopausal hormone therapy, abstinence from alcohol, history of smoking, slimming treatments, and physical activity. By means of a multivariate analysis the history of smoking was found to be significantly associated with gallstone disease when body mass index was taken into account. The significant sex difference disappeared when childbirths and age at menopause were included, which means that clinical variables specific for women in the fertile period could explain the sex difference in gallstone prevalence.

The echocardiophone: a new means for observing spatial movement of the heart.

The paper describes a new pocket size instrument called the "Cardiophone" for the diagnosis of cardiac dysfunction. It is a continuous wave swept frequency ultrasonic echo-location system which produces dynamic auditory signals corresponding to the positional change of internal structures of the heart. The four valves are relatively easy to locate compared with conventional ECG machines. Preliminary clinical evaluation results are presented indicating the potential of the instrument for the general practitioner.
