In this cross-sectional prevalence study in 1503 14-year-old Finnish schoolchildren (n = 1503) low back pain was found to be the third most common form of pain interfering with schoolwork or leisure time during the past 12 months. The lifetime cumulative incidence of low back pain was 30% and that of sciatica 1.8%. Of the 417 pupils who had experienced low back pain at some time, 39% had suffered during the past month; 65% recovered in one month from the last pain episode, while 35.2% of those reporting disabling low back pain during the past year were aware of recurrent or continual pain. Thus, 7.8% (n = 107) of the whole population could be classified as "low back pain chronics": 86% of the low back pain chronics had trouble with at least one of the daily activities listed, most commonly with sitting at school. Excluding pain in the extremities or sciatica, girls reported various pains more commonly than boys. Moreover, girls reporting recurrent low back pain had more trouble with their daily activities due to pain than boys (p < 0.001), even though the recovery from the last pain episode took the same time in boys and girls. The pupils who had had sciatica at some time, in addition to recurrent low back pain, had more trouble with the 10 daily activities than others with recurrent low back pain (p = 0.014).
Thirty-nine 15-year-old children with low-back pain (LBP) and 39 asymptomatic control children were selected from a population of 1,503 children of the same age for a magnetic resonance imaging study of the lumbar spine. Subjects with LBP were matched with control subjects by age, sex, and school class. Disk degeneration (DD) was present in 15 (38%) of the children with LBP and in 10 (26%) of the control subjects. Lumbar degeneration was most frequently associated with disk protrusion and Scheuermann-type changes. Of assessed structural abnormalities (disk protrusion, Scheuermann-type changes, transitional vertebra, and disk space narrowing), only disk protrusion was more common in children of the LBP group than in control subjects. The authors conclude that DD is a frequent finding among children with LBP at the age of 15 years. Asymptomatic (possibly physiologic) DD also is frequently found in children of this age. Whether DD associated with structural changes predisposes to low-back disorders can be confirmed only by means of a longitudinal follow-up study.
The objective of this study was to review the published literature on aetiology and treatment of nocturnal enuresis, with the aim of providing a treatment strategy which is easy for the patient and their family to follow. Results from European studies conducted over the last 15 y were included in this review. It can be concluded from the results of these studies that enuresis is the cause and not the result of a psychiatric disorder. However, there is still considerable variation in success rates, from 28 to 90%. It is of vital importance that a caring approach from the doctor and a positive family and patient attitude are present for successful treatment. The first choice of treatment should be the one most acceptable to the family, e.g. alarm, desmopressin and combination treatment.
Our data indicate that repeated child-targeted dietary counseling of parents during the first 5 years of a child's life lessens age-associated increases in children's serum cholesterol and is compatible with normal neurological development. JAMA. 2000;284:993-1000
The effect of intranasal desmopressin on primary nocturnal enuresis was investigated in a study divided into 2 parts in which the first part was a randomized, double-blind, placebo-controlled cross-over study of 52 Finnish school children 5 to 13 years old. A variety of approaches had previously been attempted in most children, including water deprivation, night awakenings, enuresis alarm and imipramine, without success. The patients were randomized to 4 periods of 3 weeks each: 2 periods on placebo and 2 periods on 20 micrograms. desmopressin spray. The entire 12-week treatment period was preceded and followed by control periods (without treatment). The number of dry nights, measured as calculated averages per week, increased significantly (p less than 0.01) from 0.6 dry nights during pre-treatment to 4.3 and 4.6 dry nights per week during the 2 desmopressin treatment periods, respectively. The placebo responses were 2.1 and 2.4 dry nights per week, respectively. The second part of the study was an open dose-finding and drug safety study of a further 3 months in duration. The aim was to evaluate the efficacy and tolerance of 20, 30 and 40 micrograms. doses. All 47 patients who relapsed during the post-treatment period in part 1 were included. During this period 53% of the patients responded fully, 19% were intermediate responders and 28% did not respond. As reported in other studies most patients suffered relapse after treatment. During continued treatment for 3 months at doses between 20 and 40 micrograms. desmopressin was well tolerated, had no effect on body weight or blood pressure and did not cause any adverse reactions.
