This is the description of the case of a 22 year old patient with low back pain and sciatica on the right side investigated by lumbar Dimer-X-Myelography. The result of the examination was an impression in the contrast column at the L5/S 1 level on the right. At operation an intradural tumour, plum-sized, well-defined, and blue-black in colour, was found and removed. Histologically the tumour was melanotic and of high cellular density, with spindle-shaped cells as well as giant cells, with round nuclei, considerable polymorphism, and atypical mitoses. On the basis of the operation finding, the clinical course, and the histology, the diagnosis is melanotic nerve sheath tumour of the first sacral root. For two years following operation the patient has experienced no discomfort.

The first clinical trials of praziquantel against Schistosoma japonicum infections in Japan were planned to assess tolerance only. Three double-blind studies against placebo involving a total of 51 patients were conducted with dosages of praziquantel of 1 x 20 mg/kg body weight, 2 x 20 mg/kg, 3 x 20 mg/kg given on one day.The frequency of unwanted side effects was higher in the group of patients given praziquantel at a dose of 3 x 20 mg/kg than in all other drug- or placebo-treated patients. In general, the side effects, which included drowsiness, headache, lumbago, abdominal fullness, or epigastric discomfort, lasted for several hours but disappeared spontaneously. The results of laboratory tests showed no significant changes caused by treatment.The overall assessment showed excellent or good tolerance in all patients treated with praziquantel at the lower dose levels. In those given 3 x 20 mg/kg, tolerance was excellent in 1 of 12 patients, good in 9, and fair in 2, whereas the respective placebo-treated group showed excellent tolerance in 3 of 12, good in 7, and fair in 2.

To determine the risk factors of the subjective symptoms experienced by chain saw workers, we surveyed 206 forestry workers using this device in their work. The strength of the relationship between their symptoms and such potential risk factors as occupational, behavioral, and physical factors was evaluated by a multiple logistic regression model. It was found that many years of chain saw operation, and numerous hours of chain saw operation per day, increased the risk of white finger, numbness of hands and arms, chillness of hands and arms and difficulty in joint movement, indicating that these symptoms were closely related to vibration exposure. Many years of forestry work before chain saw work also increased the risk of joint pain, suggesting that bone and joint disorders are related to heavy manual work not using a chain saw. A second job involving manual labor increased the risk of weakness in the arms, stiffness of the shoulders, and lumbago. Infrequent bathing was associated with increased risk of pain in hands and arms and lumbago. Older workers had a higher prevalence of stomach discomfort. No risk factor was found to significantly increase the risk of easy fatigability, forgetfulness and sleep disorder. It was found that not only exposure to vibration but also other factors contributed to the prevalence of pain in hands and arms, joint pain, weakness in arms, stiffness of shoulder, and lumbago. Second job and infrequent bathing appeared to be related to the occurrence of certain subjective symptoms. These contributory factors should be taken into account when evaluating subjective symptoms encountered in field studies of forestry workers.

Most patients with chronic low back pain associate strenuous physical activities with increased pain. This association can cause avoidance of those activities believed to cause intolerable discomfort. This study explored the relationship of performance of physical activities with self-reported pain measures in 40 consecutive patients with disabling low back pain (mean duration 17 months) during a functional restoration rehabilitation program (mean treatment period 7 weeks). Evaluations were performed at initial presentation and at program completion. Measures included quantification of performance on eight physical tests assessing flexibility, lifting capacity and endurance. Before physical testing patients were asked to complete a pain analog scale, a quantified pain drawing, and a rating of the pain anticipated to result from the performance of each physical test. Results showed that pain measures did not generally correlate with measured physical performance. At completion of treatment, significant improvement in performance on all physical tests was found, but these were not associated with consistent changes in pain measures. These results demonstrate that subjects with chronic low back pain can increase their physical performance abilities within their same pain experiences. Medical recommendations for subjects' involvement in physical activities should not be based solely on the reported association of pain with those activities.

This chapter has reviewed the role of back school and educational programmes for the common and non-specific acute and subacute low back pain patient. The following seems to come out of this review. Education is an important part of patient care. However, several questions arise about the content of the education, the selection of patients, the patient compliance to instruction given, how the information is retained, and which outcome measures should be used. It is also important to realize that the back school is a modality or a tool that may be used as an adjunct, but as a sole treatment it seems to have less impact than in combination with other structured or goal-oriented programmes. When a back school is instituted in a hospital or in industry, it requires administrative and budgetary support and a multidisciplinary staff to successfully carry out the programme. The information given must be adapted to the needs of the participants and all members of the team must give the same information to the patient. A poorly structured back school where patients are dumped because the physician or other health care provider has nothing else to offer is a poor solution for the patient, a poor solution for the health care provider, and can only increase the patient's discomfort and health care costs.

The study examined the work stresses of 107 women who were engaged in sewing machine operation in small garment manufacturing units. Of the three types of sewing machines (motor-operated, full and half shuttle foot-operated), 74% of the machines were foot-operated, where throttle action of the lower limb is required to move the shuttle of the machine. The motor-operated machines were faster than the foot-operated machines. The short cycle sewing work involves repetitive action of hand and feet. The women had to maintain a constant seated position on a stool without backrest and the body inclined forward. Long-term sewing work had a cumulative load on the musculo-skeletal structures, including the vertebral column and reflected in the form of high prevalence of discomfort and pain in different body parts. About 68% of the women complained of back pain, among whom 35% reported a persistent low back pain. Common sewing work accident is piercing of the needle through the fingers, particularly the right forefingers. Unsatisfactory man-machine incompatibility, work posture and fatigue, improper coordination of eye, leg and hand are the major problems of the operators. The design mis-match of the work place may be significantly improved by taking women's anthropometric dimensions in modifying the workplace, i.e. the seat surface, seat height, work height, backrest, etc.

Low back pain affects 80% of adults some time in their lives. It is expensive, costing more than $16 billion per year, and causes 40-50% of all lost work days. A variety of disorders can cause low back pain, but the majority of time the problem is self-limiting and resolves within a few weeks. There are specific risk factors associated with low back pain, temporary measures that can be helpful to decrease discomfort, and specific ways to prevent future episodes. The most important management modality is education, and most patients are treated in the outpatient setting. Nursing care is frequently provided by telephone. Using the nursing process, the nurse can assess and advise patients in a systematic, timely manner while maintaining a nursing focus.

This study was conducted to evaluate the relationship between the prevalence of subjective symptoms in workers using vibrating tools and the duration of chain saw operation and to examine whether the symptoms were relevant to factors other than the usage of vibrating tools. The statistical model of multivariate analysis was adapted to analyze individual data on the subjective symptoms of 317 chain saw operators. The obtained results were as follows: 1. In analysis of covariance, age-adjusted operating year in workers with peripheral circulatory, peripheral neurological and musculoskeletal disturbances was significantly longer than that without such disturbances. For these disturbances, partial regression coefficients of operating year were significantly high in multiple regression analysis. These results show that these disturbances and age-adjusted operating year are mutually closely related. 2. Multiple regression analysis showed that the partial regression coefficients of both operating year and age were low for nine symptoms, i.e. dulling sense of touch, joint pain, headache, dizziness and/or tinnitus, profuse sweating, discomfort of stomach, palpitation and/or dyspnea, hearing disturbance and lumbago. These results suggest that such symptoms were not related to either age or chain saw operation. 3. The results of principal component analysis were visualized in three-dimensional space in order to evaluate the relationships among the symptoms. The analysis showed that peripheral circulatory and neurological disturbances appeared independently and that general symptoms such as easy fatigability, headache, forgetfulness, vertigo and/or tinnitus, easy irritability, sleep disorder, profuse sweating, discomfort of stomach, palpitation and/or dyspnea, shoulder stiffness, hearing disturbance and lumbago consisted of four independent groups. Each group has no relationship with duration of chain saw operation. This suggests other harmful factors of the groups play a role in the prevalence of the symptoms.

Few validated instruments are available to assess beliefs and attitudes that patients have regarding pain, or ability to function despite discomfort. The Pain and Impairment Relationship Scale (PAIRS) was developed to tap these important beliefs and attitudes in chronic pain patients. Preliminary data indicate that the PAIRS is internally consistent and significantly related to impairment in a highly selected pain clinic sample of patients, including some chronic low back pain patients. The present study was designed to extend the validation of the PAIRS to a more general sample of chronic benign low back pain patients. Furthermore, additional tests supported the discriminant, convergent and divergent validity, as well as the reliability and relative independence from favorable self-report response bias of the PAIRS, by respectively demonstrating that: (1) the impairment beliefs assessed with the PAIRS were more prominent in chronic low back pain (CLBP) patients than in matched non-pain, healthy controls; (2) scores on the PAIRS were significantly related to measures of physical impairment, but not to physicians ratings of disease severity; (3) the impairment beliefs assessed with the PAIRS are readily distinguishable from cognitive distortions and emotional distress; (4) PAIRS scores for chronic low back pain patients are relatively consistent over time; and (5) PAIRS scores are not significantly associated with measures of favorable self-report response bias. We conclude that the PAIRS has demonstrated at least preliminary utility for applications by researchers and clinicians interested in chronic pain.

The dentists in the Public Dental Service were found to have a high prevalence of pain and discomfort in the locomotor system. Only 60 (17%) dentists reported no pain or discomfort in the study in 1987. Of 359 dentists 72 per cent reported headache and pain and discomfort in the neck and shoulders. Female dentists had a higher prevalence of pain and discomfort. Younger dentists had pain and discomfort in the neck, shoulders and headaches to a greater extent than older dentists. Male dentists, who positioned their patient carefully to gain a direct view suffered less from headache. Furthermore, dentists who used the mirror reported less headache and pain and discomfort in the shoulders. Differences in working position in a simulated case were analysed during a visit to the workplace of 143 dentists. The ergonomic examination showed that dentists without symptoms applied a wedge cushion under the upper part of the patient's back to obtain an optimum view when they examined tooth 2 6 d. They also made use of the pauses intrinsic in the work. The dentists with symptoms experienced the workload as more unsatisfactory, were more burdened by anxiety, had poorer psychosomatic health and less confidence in the future than the dentists without symptoms. Specialists, both with and without cervico-brachial symptoms, were more satisfied with their personal control over their work and the stimulation from their work than were general practitioners. The specialists also had more self-confidence, and experienced less anxiety than general practitioners and head dentists. Physiotherapy with a psychosomatic approach and individual ergonomic instruction gave better relief from pain and discomfort and an increased feeling of mental well-being than did ergonomic instruction only. In the prospective study it was found that the prevalence of musculoskeletal pain and discomfort had increased since 1987, except with respect to low back pain and headache. However, the only significant difference was found with respect to the shoulders. As in 1987, female dentists had a higher prevalence of pain and discomfort in the neck and shoulders than their male colleagues in 1990. It can be concluded that pain and discomfort in the locomotor system among dentists had a high incidence. The high incidence among dentists could not be explained by the ergonomic risk factors such as positioning of the patient, use of the mirror or alteration of the dentist's position. Regression analysis showed that personal harmony and age had the highest value for explaining the number of painful sites in the musculoskeletal system.
