Spontaneous healing of aneurysmal bone cysts. A report of three cases.

We report three cases of spontaneous healing of aneurysmal bone cysts (ABC). In one case histological material was obtained after resection of the already ossified expansile mass discovered as a lytic lesion seven months previously. In the two other patients, spontaneous ossification of a radiologically presumed ABC in the lytic and expansile phase was observed after nine and seven months respectively. The healed lesions have remained stable at 12, 32, and 36 months respectively. These findings suggest that when the diagnosis can be made with confidence, and the lesion is in a location and at a stage that does not entail any risk of fracture or compression, expectant management should be considered. Our three patients were aged 22, 19 and 18 years, older than usual for developing ABC. This is also true for many of the few other reported cases of spontaneous or almost spontaneous healing and suggests that ABC has a greater tendency to stabilise in older patients.

Pustulotic arthroosteitis and chronic recurrent multifocal osteomyelitis in children. Report of three cases.

We describe 3 children with pustulosis palmaris et plantaris associated with chronic recurrent (multifocal) osteomyelitis, located in the clavicle in 2 patients, and in the distal fibula as well as in several metatarsals in the third. The first 2 children also developed inflammatory sacroiliitis, one with chronic peripheral polyarthritis. These 3 cases represent the arthrosteitis and chronic recurrent multifocal osteomyelitis syndrome associated with palmoplantar pustulosis.

New modes of administration of salmon calcitonin in Paget's disease. Nasal spray and suppository.

In volunteers the activity of various doses of a nasal spray and of a suppository of salmon calcitonin was compared to a placebo and to the parenteral route of administration. Both new modes of administration were found to be active on the kidney (and the suppository was found to affect bone turnover as well). The parenteral route proved more effective, but the nasal and/or rectal routes were devoid of systemic side effects and had minimal local intolerance. The nasal spray was used at 200 units daily in 15 patients with Paget's disease, and at 400 units daily in another nine patients, both trials lasting one year. The two regimens proved active on the parameters of bone turnover and the higher dose was more effective than the lower one. Similarly, a 300 unit suppository was given to another 12 patients. This trial is still being completed at this time. At the third month of therapy, the parameters of bone turnover were significantly depressed. Both new modes of therapy were able to improve the focal bone balance of the osteolytic lesions monitored on sequential roentgenograms. Systemic side effects were absent and local side effects were minimal. Only one patient interrupted the nasal spray therapy, and no one interrupted the suppository therapy.

Reflex sympathetic dystrophy syndrome: an unusual mode of presentation of osteomalacia.

We report 2 patients with reflex sympathetic dystrophy syndrome (RSDS) associated with renal tubular osteomalacia. In both patients, RSDS was the presenting manifestation. Treatment of the underlying condition with calcitriol resulted in healing in both patients. These cases prompted us to undertake a retrospective study of 24 consecutive patients with osteomalacia (6 of renal tubular origin, 18 related to vitamin D deficiency), and of 259 consecutive patients with RSDS. Among those with osteomalacia, radiologic lesions strongly suggestive of RSDS were found in 5 patients (21%), 4 of whom had renal tubular defects, and only 1 had vitamin D deficiency. In the group with RSDS, 1 patient (0.4%) was found to have osteomalacia of renal tubular origin. Thus, radiologic findings suggestive of RSDS are frequent in patients with osteomalacia, especially that of renal tubular origin. On rare occasions, the full-blown clinical picture of RSDS may obscure the diagnosis of osteomalacia.

Sciatic neuropathy at the popliteal fossa: clinical, ultrasonographic and computed tomographic diagnosis.

A 22-year-old female had been suffering from sciatica-like pain in the left leg for four years. Clinical findings strongly directed further investigations to the popliteal fossa. Ultrasonography located a hypoechogenic mass in the upper lateral popliteal space. Guided by these data, computerized tomography (CT) with vertical reconstructions made the tentative diagnosis of a common peroneal nerve tumor, which was confirmed at operation. Microscopic examination showed a neurinoma of the mixed neurilemmoma-neurofibroma type. In the presence of atypical features of sciatica, a high index of suspicion seems advisable. Emphasis is laid on the complementary contribution of ultrasonography and CT in this type of ill-defined lower limb pain.

An evaluation of criteria for polymyalgia rheumatica.

There has been little basis on which to standardise a diagnosis of polymyalgia rheumatica (PMR), and so 11 rheumatology units in the south and west of Great Britain have collaborated in a study to evaluate possible criteria. Symptoms and laboratory findings claimed to be of diagnostic value in PMR were included in an analysis of the features of 236 patients considered to have unequivocal PMR and 70 patients thought to have possible PMR. The results were compared with similar information from 253 patients with conditions that mimic PMR and from 201 consecutive new presentations to outpatients. The 7 most valuable criteria for differentiation were bilateral shoulder pain or stiffness, onset of illness of less than 2 weeks' duration, initial ESR greater than 40 mm/h, duration of morning stiffness exceeding 1 hour, age 65 years or more, depression and/or weight loss, and bilateral tenderness in the upper arms. We suggest that a patient might be regarded as having probable PMR if any 3 or more of these criteria are fulfilled, or if at least 1 criterion coexists with a clinical or pathological abnormality of the temporal artery. A standardised therapeutic test with prednisolone has value in making the diagnosis of PMR more certain.

A thermographic assessment of three intra-articular prednisolone analogues given in rheumatoid synovitis.

1 Three intra-articular prednisolone analogues have been studied in a group of forty-six rheumatoid arthritic subjects. Each compound was tested at 50 mg and 100 mg dose over 3 weeks. 2 The anti-inflammatory effect was assessed by quantitative thermography. Systemic escape of the drug was monitored by plasma prednisolone and cortisol levels. 3 Both the systemic escape from the joint and the duration of effect on injected and uninjected knees were related to drug solubility. 4 Depression of plasma cortisol occurred with all three preparations and was most prolonged with the long-acting preparation. 5 Increasing the dose from 50 mg to 100 mg increased the antiflammatory effect only with the soluble acetate preparation.

Polymyalgia rheumatica. Abrupt and gradual withdrawal of prednisolone treatment, clinical and laboratory observations.

Eighteen patients with polymyalgia rheumatica had corticosteroid treatment withdrawn abruptly under close observation. In each case polymyalgic symptoms reappeared but were controlled rapidly when prednisolone was reintroduced. Prednisolone withdrawal was then started by slow decrements of dose. In no patient was it possible to withdraw prednisolone treatment, after using either method, during the period of observation.

Polymyalgia rheumatica. Assessment of disease activity using erythrocyte sedimentation rate and plasma viscosity.

Comparison of clinically assessed activity of disease with 112 paired readings of the erythrocyte sedimentation rate (ESR) and the plasma viscosity (PV) in 23 patients with polymyalgia rheumatica (PMR) showed the following. (1) A correlation between ESR and PV in both sexes, reaching the significance obtained in a comparison group of patients with rheumatoid arthritis (RA) (109 paired readings), with no significant difference between the PMR and RA groups on analysis of variance of the regression slopes. (2) A degree of scatter of readings around the regression lines so that they could not be used for prediction of ESR from the PV or vice versa. (3) varkappa(2) analysis of normal and abnormal values of ESR and PV which showed a highly significant correlation. However 10 readings were abnormally high for ESR in the presence of a normal PV. 5 of these 10 observations were associated with clinical features of disease activity. 20 readings were abnormally high for PV in spite of a normal ESR with only one instance of clinical activity. These data indicate that it is not possible to provide exact guidelines for a ;safe' level of ESR or PV applicable to the individual patient, and measurement of both these indices of disease activity is recommended.

Circulating immunoblasts in polymyalgia rheumatica.

The percentage of immunoblasts circulating in the peripheral blood has been examined in a group of 29 patients with polymyalgia rheumatica (PMR). Less than 0.5% of immunoblasts were found in healthy young controls, but 18 of 29 unselected patients with PMR were positive when first tested, a similar proportion to that found in rheumatoid arthritis. Raised immunoblasts were found in only one of 12 elderly controls. The presence of circulating immunoblasts correlated with the activity of polymyalgia both as assessed by the erythrocyte sedimentation rate (ESR) and as assessed by an independent clinical observer. This was true in the group overall and in those patients where serial studies were made. Patients studied from the time of disease presentation showed a concurrent fall in ESR and in immunoblasts on starting steroid therapy. Detection of circulating immunoblasts can be a useful additional test in the assessment of disease activity in PMR, especially in cases with a low ESR. The presence of circulating immunoblasts supports the concept of an immunological aetiology for PMR. This is strengthened by the finding that raised immunoglobulins were more common in patients with circulating immunoblasts.
