A group of 109 patients with unilateral low back pain for over three months were randomised to receive one of three types of injection treatment: cortisone and local anaesthetic injected into two facet joints (28), the same mixture around two facet joints (39), or physiological saline into two facet joints (42). The effect of the treatment was evaluated in relation to work attendance, pain, disability and movements of the lumbar spine. Patients were examined one hour and two and six weeks after treatment and also completed a questionnaire after three months.

Probands with clefts born during an 11-year period, 1975-85, were evaluated; 1,586 probands were found of whom 345 (171 males and 174 females, 21.8%) had an associated anomaly. More male patients had cleft lips, with or without cleft palate (CL(P)) and more female patients had cleft palates (CP). The anomalies were subdivided according to anatomical site, and the biggest category was that of the extremities (29.7%) followed by cardiovascular (14.8%) and other facial anomalies (13.0%). The smallest category was chromosomal anomalies (2.7%) followed by miscellaneous anomalies (4.1%). A total of 560 malformations were found. Most anomalies per proband with clefts were found in the bilateral cleft lip and palate subgroup (mean 1.04). The lowest (0.14) was found in the subgroup with the least severe cleft deformity, the cleft lip with or without cleft alveolus. In the CP groups a similar trend was found with 0.21 in the subgroup of submucous cleft palate and 0.33 for the subgroup cleft palate, submucous clefts excluded. A total of 133 probands with 39 different recognised syndromes was delineated, 25 in the CL(P) group and 108 in the CP group (8.4% of the total 1,586 patients with clefts). There was no difference in parental age between probands with an associated anomaly and those with a solitary cleft. Anomalies were more than three times as frequent among probands with clefts as among the general population.

The mean birth weight of the 1,568 probands with clefts who were born in Finland between 1975 and 1985 was 3,346 g, which is lower than the mean of all live born babies in 1980 (3,541 g). The 345 who had an associated anomaly or syndrome had a mean birth weight of 3,027 g and placental weight of 538 g, compared with 3,435 g and 609 g, respectively, for those with solitary clefts. The more severe the cleft the lower the birth weight, but not the placental weight. The percentage of low birthweight (less than or equal to 2,500 g) infants was higher than in the general population (8.5% compared with 3.8%). The highest percentage of low birthweight infants was in the subgroup with bilateral cleft lip and palate (16.8%).
