[Low-energy laser therapy in medial tibial stress syndrome].

The effect of low-energy laser therapy on shin splints was examined in a randomized study with an unblinded design. Constripts from the Jutland Dragoon regiment with shin splints were given either active laser treatment (40 mW in 60 sec per cm tender tibia edge) or placebo laser. All patients were exempted from normal duty concerning activities like running and march. Forty-nine patients participated in the study, 23 in the laser group and 26 in the control group. From the start the study was designed to be double-blind, but by accident the code was broken towards the end of the study. We found no significant differences between the groups regarding pain visual analog score and readiness to return to active duty after 14 days.

[Diagnostic activity in general practice. 3. Diagnosis of breast diseases].

A random sample of 483 women from five practices representing a basic population of 4,867 women over the age of 35 years was selected in order to assess the examination activity for cancer of the breast. The examination activity in practice decreased with increasing age simultaneously with increase in the incidence of cancer of the breast. The possibility for a 93% total screening per five years is present but does not appear to be practically feasible. All of the positive findings occur in women seeking advice on account of symptoms. Instruction in self-examination will probably result in an increased number of referrals for this reason. Among the possibilities for teaching self-examination and regular control, women receiving hormonal contraception and women receiving substitution therapy at the menopause are suggested as possible clienteles. In both of these cases, annual examination of the breast should be performed in advance.

[Diagnostic activity in general practice. 1. Patients' contact patterns in rural and urban general practices].

Contact with patients was described retrospectively for a period of five years by means of careful notes from the case records in five general practices in urban and rural areas chosen at random as a representative spot test. A total of 968 persons in group 1 of the Danish National Health Insurance (98-99% of the population), 485 men and 483 women or 9.7% of the group 1 insured persons over the age of 30 years had 10,410 consultations. This corresponds to 2.15 consultations per annum for persons in group 1 insurance. 91% of the patients visited the consultation. 17% of all the patient, twice as many women as men, were responsible for 50% of all the consultations. Women had 45% more consultations than men. Women in the age group 35-54 years constituted the group where most persons of the group visited general practice and this group had also the greatest total number of consultations, viz 30% of the total. Significantly more women than men had many consultations in this age group while significantly more men than women had only few consultations in the age group between 35-44 years. Expressed in percentages, the age group 55-64 years showed greatest similarity between men and women. Half of the men and slightly more than one third of all the women consulted their practitioners once per annum or more rarely. Patients of 75 years or over consulted their general practitioners most frequently.

[Diagnostic activity in general practice. 2. Frequency of examination of urinary glucose and blood pressure determination among patients in general practice].

In order to estimate how frequently examinations of urine for glucosuria and blood pressure measurements are performed in the primary health care sector to detect common incapacitating diseases such as diabetes and hypertension, the authors carried out a study in five general practices in Denmark for a period of five years. The study was retrospective because it is not possible to study one's own behaviour prospectively. Nearly 1,000 persons aged 30 years or more were involved. 9% of the group had no contact with the health care sector during the period. In 49%, the urine had been tested at least once for glucose; 58% where women were concerned but only 40% of the men. Men under the age of 55 years were significantly underrepresented. Examination of the urine was only undertaken in 51% of the persons aged 55-74 years. Twelve new cases of diabetes were discovered, nine of these were diagnosed in general practice. Hypertension had been diagnosed in 52 patients before the registration period. 60% of the remainder had blood pressure measurements on at least one occasion during the period. Men under 55 years were significantly underrepresented (42%). Sixty-four new cases of hypertension were discovered, 59 of these in general practice. Screening for common diseases such as these is primarily performed by general practitioner. Several other works from general practice where no special efforts were made to systematize screening for diabetes or hypertension did not reveal any better results. It is estimated that 25% of diabetic patients and 50% of hypertensive patients remain undiagnosed. The present rather random screening for these diseases is insufficient.(ABSTRACT TRUNCATED AT 250 WORDS)

Pleural empyema in a newborn infant. An unusual cause of respiratory distress.

In a 2-day-old baby with symptoms of respiratory distress a right-sided pleural empyema caused by haemolytic streptococci was found. Possible sources of infection are discussed. The mother had purulent discharge from a tooth a few weeks before delivery, and this may have been the focus. The baby was treated with pleural drainage and ampicillin with good result.

Auscultatory measurement of blood pressure performed by the doctor on duty.

A review is presented of the measurements of blood pressure on admission of 600 patients to the wards in a department of general medicine. Three doctors each examined 200 patients, distributed over two periods with an interval of one year. Large differences were found between the doctors as regards the distribution of the BPs, particularly the diastolic pressures. On the other hand, no differences were observed in the distributions during the two periods as far as the individual doctors were concerned. Great preference was shown for zero as the terminal digit and also for certain BP values. It is concluded that the observer introduces a considerable subjective factor in measuring the BP by auscultation. Correct performance of this simple procedure requires meticulous instruction.
