We report the association of a cutaneous lesion with multiple endocrine neoplasia type 2A (MEN 2A) in three patients from a French family. These lesions are very similar to those previously described in an Italian and an American MEN 2A family and called cutaneous lichen amyloidosis. In all three families the patients presented with a pruritic and pigmented cutaneous lesion localized unilaterally on the upper back. However, in the French family the patients also complained of paroxysmal pain in the same area, in which we could elicit a touch hypoesthesia and pain hyperesthesia. Such an association of cutaneous and neurological features in the upper back is known as Notalgia Paresthetica (NP). NP is believed to represent a neuropathy of the posterior dorsal nerve rami. Unlike the two previously reported families, the histological, immunohistochemical and ultrastructural analysis of the skin biopsies of the French patients did not show any amyloid material. This suggests that the presence of amyloid may not be a constant feature of the cutaneous lesions associated with MEN 2A. We consider these lesions as a form of dorsal neuropathy rather than a cutaneous lichen amyloidosis. Whatever their origin, these cutaneous lesion usually precede the appearance of the neoplastic lesions of MEN 2A. They may act as an early clinical marker that must be searched for in each subject at risk for MEN 2A. In addition, all patients presenting with NP should be screened for MEN 2A.

We have reviewed our experience with 43 cases of bacterial spinal epidural abscess, as well as previously reported series of cases. We found a striking male predominance of the disease, accounting for 86% of cases. Most patients had some underlying conditions that predisposed to infection, a prior infection at a distant site, or an abnormality or trauma to the spine. Presenting symptoms included backache (72%), radicular pain (47%), weakness of an extremity (35%), sensory deficit (23%), bladder or bowel dysfunction (30%), and frank paralysis (21%). Patients cared for in public hospitals tended to seek medical attention in later stages of the disease than patients admitted to private hospitals. Spinal epidural abscess was the suspected diagnosis in only 40% of the cases; the remainder of the time various other infections, tumors, neurologic diseases, or degenerative conditions were considered. Patients in whom the diagnosis of spinal epidural abscess was not initially entertained on admission suffered delays in diagnosis and experienced neurologic deterioration. Staphylococcus aureus was the predominant pathogen (65%) and was associated with positive blood cultures in nearly every case; aerobic or facultative gram-negative bacilli were next most common. Coagulase-negative staphylococci caused infection only in patients who had previous spinal instrumentation. Although analysis of CSF was abnormal in the majority of cases, abnormalities were nonspecific, Gram stain was always negative and culture was rarely diagnostic. Abscesses extended over an average of 4 vertebrae, and the majority were located in the lumbar region followed by thoracic and cervical regions. Unlike previous series, we noted an equal frequency of anterior and posterior epidural abscesses; although differences were not statistically significant, posterior abscesses tended to be more extensive but less commonly associated with radiographic abnormalities of osteomyelitis. Myelography revealed an abnormality in every case in which it was done. Computerized tomographic scanning after intrathecal injection of contrast material always provided additional useful information. Even though magnetic resonance imaging was diagnostic in only 4 of 5 cases (80%) in our series, this test is noninvasive and clearly delineates the location and nature of spinal lesion. It should, therefore, probably replace myelography as an initial definitive study in patients suspected of having spinal infection. Plain roentgenograms and nuclear scans contributed little useful information that was not already available from other radiographic procedures. Surgical drainage together with antibiotics was the treatment of choice; 35 of our 43 patients underwent operative intervention. The preoperative status clearly predicted the final neurologic outcome.(ABSTRACT TRUNCATED AT 400 WORDS)

A parallel investigation of the success of treating patients with chronic low back pain has been carried out at the Moravci Spa, at the Department for Physical Therapy and Rehabilitation and at the Rheumatology Department of Maribor Teaching Hospital. One hundred patients suffering from low-back pain were given a 14-day treatment in the termomineral water (T--36 degrees C) of the Moravci Spa. A comparative group of another 100 patients also suffering from pain in the lumbar region of the spine underwent equal balneo-physical treatment in plain water (T--32 degrees C) at the Dept. for Physical Therapy and Rehabilitation and at the Dept. of Rheumatology at Maribor Teaching Hospital, Slovenia. The educational background of the two groups features a statistically significant difference (p < 0.001): the percentage of patients with lower education was higher at the Moravci Spa (67%) compared with only 46% among those treated at Maribor Teaching Hospital. Correspondingly, the difference in occupation of the two groups were similar (p < 0.005): prevalent among the patients at Moravci Spa were bluecollar workers (40%) compared with white-collar workers (27%). The percentage of white-collar workers at Maribor Teaching Hospital was 45%. The average age of the patients treated at the Moravci Spa was 46.9 +/- 9.5 years (28-77 years), at Maribor Teaching Hospital it was 45.2 +/- 8.2 years (26-71 years). There was no statistically significant difference in age (p < 0.10) between the two groups. Generalized spondylochondrosis was present in both groups, i.e. 87%; approximately 10% of the patients from both groups underwent surgical treatment of hernia disci.(ABSTRACT TRUNCATED AT 250 WORDS)

The results of a prospective study of 134 patients with lower back pain suggest that nonorganic factors are better predictors of return to work than organic findings. Patients who returned to work had fewer job, personal, or family related problems. There were no significant differences between patients who returned to work and those who did not when comparing myelograms, computed tomographic scans, or roentgenographs. The only significant difference in physical organic findings was for muscle atrophy. Patients who did not return to work had a statistically higher incidence rate of muscle atrophy. Length of time off from work was significantly related to outcome, but when patients were categorized according to time off the job, different factors predicted failure to return for patients off work for less than 6 months and patients off for more than 6 months. For patients off for less than 6 months, important predictors were a high Oswestry score, history of leg pain, family relocation, short tenure on the job, verbal magnification of pain, reports of moderate to severe pain on superficial palpation, and positive reaction to a "sham" sciatic tension test. None of these was a significant predictor for the group off for more than 6 months. For the group off work for more than 6 months, previous injuries, and stability of family living arrangements were among the significant predictors not significant for the group off less than 6 months. Using 21 factors selected from a larger group of 92 factors, three statistically significant (P less than or equal to 0.001) predictive measures were developed. These measures predicted return to work for the total sample, and for the two subgroups (off more than, or less than 6 months) more accurately than did the total set of 92 factors.

Back spasm, or spasm of the back muscles, is the commonest adverse reaction encountered after chemonucleolysis. In order to overcome this troublesome complication, the authors present a new 'paradiscal injection technique'. After the injection of chymopapain into the affected disc, the needle is withdrawn to just outside the annulus. Bupivacaine is injected into the paradiscal 'space' which acts upon the paravertebral muscles. Eighty consecutive patients have been treated by chemonucleolysis with paradiscal injection for pain relief. All patients were discharged the same day or the following day and no immediate complications occurred. When reviewed 3 weeks later, only three (3.8%) patients complained of back pain (which was different in character to that present before the injection or was exacerbated by the injection). Pain persisted in the same patients until 6 months after the injection but was negligible. None of the remaining patients had developed back pain as a result of chymopapain. The authors suggest that the addition of paradiscal injection of bupivicaine after cymopapain injection can reduce the incidence of spasm of the back muscles. This technique is a major contribution to increasing the efficacy of chemonucleolysis for the treatment of herniated lumbar disc.

Back pain questionnaires were completed by a study group of 103 idiopathic scoliosis patients fused with Harrington rods from L3 or lower and a control group of 29 patients fused to L2 or above. Minimum time to follow-up examination was 2 years. The study group had a higher rate of secondary surgeries for complications or late disc disease below the fusion, a higher back pain score, more difficulties with normal daily activities, needed more regular pain medications, and had more episodes of back pain. Patients older than 30 years at surgery had more of these problems if fused to L3 or more caudally. The amount of remaining lumbar lordosis correlated significantly with the difficulty of normal daily activities.

Even the careful and knowledgeable spine surgeon will encounter a variety of neurologic complications during and after routine lumbar laminectomy. These include dural and nerve root injuries; cauda equina syndrome; and formation of scar tissue, extradural and intradural (arachnoiditis). The surgeon must be prepared to identify each of these problems and deal with them effectively at the time of the procedure and in the immediate postoperative and follow-up periods. The physician evaluating the multiply-operated lumbar spine patient must use an organized approach. The origin of the problem in most instances is a faulty decision to perform the original operative procedure. Further surgery on an "exploratory" basis is not warranted in any situation and most likely will lead only to further disability. There should be definite objective findings to substantiate the patient's symptoms. The etiology of each patient's symptoms. must be accurately localized and identified. Medical status and psychosocial situation--as well as orthopedic and neurologic findings--should be evaluated at the time of the initial consultation. Once the spine is identified as the probable source of symptoms, specific features should be sought in the patient's clinical history, physical examination, and roentgenographic studies. The number of previous operations, length of pain-free interval, and predominance of leg versus back pain are the major historic signposts. The presence of a tension sign and the neurologic findings are the focal points of the physical examination. Plain roentgenograms, motion films, water-soluble myelogram, computed axial tomography, and magnetic resonance imaging with contrast have specific roles in the workup.(ABSTRACT TRUNCATED AT 250 WORDS)

This research develops and evaluates a simple method of grading the severity of chronic pain for use in general population surveys and studies of primary care pain patients. Measures of pain intensity, disability, persistence and recency of onset were tested for their ability to grade chronic pain severity in a longitudinal study of primary care back pain (n = 1213), headache (n = 779) and temporomandibular disorder pain (n = 397) patients. A Guttman scale analysis showed that pain intensity and disability measures formed a reliable hierarchical scale. Pain intensity measures appeared to scale the lower range of global severity while disability measures appeared to scale the upper range of global severity. Recency of onset and days in pain in the prior 6 months did not scale with pain intensity or disability. Using simple scoring rules, pain severity was graded into 4 hierarchical classes: Grade I, low disability--low intensity; Grade II, low disability--high intensity; Grade III, high disability--moderately limiting; and Grade IV, high disability--severely limiting. For each pain site, Chronic Pain Grade measured at baseline showed a highly statistically significant and monotonically increasing relationship with unemployment rate, pain-related functional limitations, depression, fair to poor self-rated health, frequent use of opioid analgesics, and frequent pain-related doctor visits both at baseline and at 1-year follow-up. Days in Pain was related to these variables, but not as strongly as Chronic Pain Grade. Recent onset cases (first onset within the prior 3 months) did not show differences in psychological and behavioral dysfunction when compared to persons with less recent onset. Using longitudinal data from a population-based study (n = 803), Chronic Pain Grade at baseline predicted the presence of pain in the prior 2 weeks. Chronic Pain Grade and pain-related functional limitations at 3-year follow-up. Grading chronic pain as a function of pain intensity and pain-related disability may be useful when a brief ordinal measure of global pain severity is required. Pain persistence, measured by days in pain in a fixed time period, provides useful additional information.

101 outpatients with acute or subacute low-back pain were randomly allocated to one of two treatment groups. One group was given standardized conventional but optimal activating treatment by primary health care teams. The other group received manual treatment such as manipulation, specific mobilization, muscle stretching, auto-traction, and cortisone injections. The two groups were similar in most of the pretrial variables, including age, sex, previous low-back pain problems, sick-leave, previous treatment, findings at the physical examination, quality-of-life score, disability rating, and pain score. After one month in the study, the proportion of patients on sick-leave was six times larger in the conventionally treated group than in the group receiving the specific manual treatment. The difference diminished over time but was still significant after eight months. Two slightly different pain scores ("pain at the moment" and "pain during the last weeks"), initially similar in the two groups, diminished in both groups but were significantly lower in the manual treatment group during the study. The group receiving specific manual treatment thus had a significantly better outcome than the group receiving conventional treatment as far as sick-leave and pain score are concerned.

An unselected sample of outpatient subjects (n = 330) with localized nonspecific low back pain (LBP) was studied. Investigation consisted of clinical assessment, physical examination, and psychiatric interview based on the DSM-III classification. A psychiatric disorder, according to the DSM-III criteria (axis I) was found in 41% of the subjects. Multiple correspondence analysis and cluster analysis were used to objectively identify clinical subtypes without preconceived theoretical models. Correspondence analyses suggested the existence of a 'psychological pain' syndrome consisting of several of the following symptoms: diffuse back pain, impossibility to assess intensity of pain on a pain scale, aggravation of pain by changing climate, by domestic activities or by psychological factors and dysesthesias in the back. Cluster analysis provided support for a four-group classification of low back pain, which may be interpreted through the relationships between psychological disturbances and the LBP clinical features. The results call for further investigation of the complex relationship between psychological disturbances and back pain. However, clinicians must be aware of the interest of a minimal psychiatric assessment in low back pain patients: psychiatric disorders frequently appear in these patients and an appropriate treatment of the psychiatric syndrome may reduce back pain.
