Abstract
OBJECTIVES To determine the feasibility of assessing patellofemoral osteoarthritis using the 'skyline' view and to compare its reproducibility with the standard lateral view. METHODS Fifty patients attending a rheumatology outpatient department with osteoarthritis of the knee had standard radiographs taken of both knees: standing weightbearing anteroposterior; lateral supine radiograph in 30 degrees of flexion; and a skyline view of the patellofemoral joint. After an initial training period using 20 sets of films the remaining 30 sets were read blind by five observers. Intraobserver and interobserver variability was assessed using the kappa statistic. The minimum joint space in each compartment was measured using a ruler. Two views of a single normal subject were measured to determine the effect of knee flexion. RESULTS The final 30 study films were from 20 women and 10 men, median age 72.5, range 18-91 years. A grading system comprising assessment of osteophytosis, joint space narrowing, sclerosis, cysts, and attrition could easily be applied to the skyline patellofemoral view. Intraobserver reproducibility was better than the interobserver reproducibility for all features. The skyline view performed more reproducibly and over a wider range of categorisation for joint space narrowing than the lateral radiograph. Measurement using a ruler was easy to perform and precise to within 1 mm for the medial tibiofemoral and lateral facet of the patellofemoral joint. In normal knees the degree of flexion significantly affected the measurement. CONCLUSIONS Radiographic grading of the skyline patellofemoral view is readily achieved, is more reproducible than assessment of the lateral view, and allows more precise localisation of change. Such views should be considered in radiological surveys of osteoarthritis of the knee.

Abstract
OBJECTIVES--To investigate urine neopterin as a parameter of disease activity in an unselected group of patients with systemic lupus erythematosus (SLE) and to study the relation between urine neopterin and certain patterns of organ disease and differing drug regimens in the treatment of SLE. METHODS--Neopterin was determined by high performance liquid chromatography in 115 early morning urine samples from 68 patients with SLE. Serum soluble interleukin 2 receptor (sIL-2R) and antibodies to double stranded DNA (dsDNA) were determined by enzyme linked immunosorbent assay (ELISA), and the erythrocyte sedimentation rate (ESR), plasma C3, C4, and C3 degradation products (C3dg) were measured in corresponding blood samples. Disease activity was scored using the British Isles Lupus Assessment Group (BILAG) index. RESULTS--Urine neopterin was significantly increased in patients with active and inactive SLE compared with the control group and was significantly higher in patients with active than in those with inactive SLE. Urine neopterin did not distinguish between subsets of patients with SLE with particular patterns of organ disease, as defined by the BILAG index, nor was its level primarily influenced by differing drug regimens. Levels of serum sIL-2R, antibodies to dsDNA, the ESR, and plasma C3, C4, and C3dg were also significantly different between the patients with active and inactive SLE. Unlike urine neopterin there was considerable overlap in the values of these parameters between the two activity groups. Highly significant correlations found between urine neopterin and serum sIL-2R, ESR, and plasma C3, C4, and C3dg suggest the close association of neopterin with clinical activity in SLE. Multivariate logistic regression analysis showed that urine neopterin > 300 mumol/mol creatinine was a highly significant predictor of disease activity with an odds ratio of 3.51. CONCLUSIONS--Determination of urine neopterin, a non-invasive, relatively simple and inexpensive measurement, appears to be the best parameter for assessing and monitoring disease activity and treatment in patients with SLE.

Abstract
Mucormycosis (phycomycosis, zygomycosis) is an acute opportunistic infection caused by a saprophytic fungus found in soil, bread molds, and decaying fruits and vegetables. Numerous predisposing risk factors are associated with mucormycosis, although most cases have been reported in poorly controlled diabetics or in patients with hematologic malignant conditions. This report presents two cases of oral mucormycosis. One case occurred in the maxilla in a patient with well-controlled diabetes. The other involved the mandible and overlying gingiva in a patient with acute myelogenous leukemia. A review of the literature concerning oral mucormycosis is also presented.

Abstract
Although the most common oral manifestation of osteogenesis imperfecta is dentinogenesis imperfecta, several authors have described jaw fractures and radiolucent bone lesions associated with this disease. We report a case of a 23-year-old white woman with osteogenesis imperfecta and dentinogenesis imperfecta who developed multiple unilocular, bilateral, radiolucent lesions of the mandible 5 years after presenting with a condylar fracture. This is the first documentation by surgical and histopathologic examination that the radiolucent lesions in this particular case represent multiple idiopathic bone cysts.

Abstract
Cytomegalovirus is responsible for a significant percentage of asymptomatic viral infections worldwide. Although virtually any cell or organ may be infected, involvement of the oral cavity is uncommon. Only nine well-documented examples of intraoral cytomegalovirus infections were found in a review of the English-language literature. We report six additional examples, five of which possessed unique clinical and histopathologic characteristics. The light and electron-microscopic features of cytomegalovirus are discussed, as well as diagnostic adjuncts such as immunohistochemistry and deoxyribonucleic acid in situ hybridization.

Abstract
Oral vaccines may contain adjuvants which might elicit allergies against dietary proteins. Four antigens were used to measure such an effect--ovalbumin, soya bean protein, lactalbumin and gluten. Neither guinea pigs nor mice showed IgE responses after oral administration of adjuvanted vaccines containing lactalbumin and gluten. No IgE responses were detected in mice with any of these antigens after oral immunization, but, in the guinea pig, nine out of 18 animals reacted to either ovalbumin or soya bean protein and none reacted to lactalbumin and gluten. It is concluded that the risk of allergy induction against normal dietary proteins is low but such tests should be applied to potential adjuvanted oral vaccines to measure any possible contraindication, especially with atopic individuals.

Abstract
Although many metabolic and endocrine diseases have been reported to predispose to calcium pyrophosphate dihydrate crystal deposition, the validity of many of these associations remains unclear. A critical review of the literature relating to these associations, with illustrative cases and data derived from the authors' own experience, is presented. It is concluded that there is good evidence to associate hypophosphatasia, hypomagnesemia, and hyperparathyroidism with chondrocalcinosis and acute attacks of "pseudogout." Meta-analysis also suggests a small but significant association between hypothyroidism and chondrocalcinosis. Hemochromatosis stands alone in clearly associating not only with chondrocalcinosis but also with structural change and chronic arthropathy. The biochemical mechanisms that may produce these various associations are discussed. Recommendations are made concerning appropriate screening for metabolic and endocrine disease in patients with chondrocalcinosis.

Abstract
OBJECTIVE Recently, 2 classes of cytokine inhibitors have been defined at the molecular level. The largest group comprises the extracellular domains of cell surface cytokine receptors, and includes both tumor necrosis factor receptors (TNF-R). The present study was conducted to investigate the role of TNF inhibitors in arthritis. METHODS We measured p55 and p75 soluble TNF-R (sTNF-R) in serum and synovial fluid (SF) samples from patients with rheumatic diseases and compared their levels with levels of soluble interleukin-2 receptors (sIL-2R). Sensitive enzyme-linked immunosorbent assays (ELISA), specific for p55 and p75 sTNF-R and for sIL-2R, were used. RESULTS Serum levels of p75 sTNF-R were 3-4-fold higher than levels of p55 sTNF-R, and both were significantly elevated in patients with osteoarthritis (OA) and rheumatoid arthritis (RA) compared with healthy controls. RA SF levels of sTNF-R were 4-5-fold higher than levels in serum, suggesting local production in the joint, and were significantly higher than levels in the SF of patients with seronegative arthropathy or OA. Furthermore, levels of p55 and p75 sTNF-R, but not sIL-2R or TNF alpha measured by ELISA, were increased in the SF of patients with clinically active RA. The soluble TNF-R in RA and OA SF were functional since they inhibited TNF activity in a cytotoxicity assay in proportion to the levels of inhibitor present. Evaluation of serially obtained serum samples suggested that sTNF-R may be a useful parameter for monitoring RA disease activity. CONCLUSION Biologically active soluble TNF-R are up-regulated in patients with rheumatic disease and are produced locally in the joints. Measurement of serum levels of TNF-R may be useful for monitoring of disease, and determination of SF levels could be of diagnostic value.

Abstract
Numerous publications have reviewed the oral manifestations of HIV infection and AIDS. Although uncommon, herpetic infections and histoplasmosis are among the diseases reported. The case that follows presents the first description of the simultaneous occurrence of oral herpes simplex virus, cytomegalovirus, and histoplasmosis in an HIV-infected person. These infections appeared as extensive oral ulcerations and were the only clinical manifestation of HIV infection. Eleven months after the initial presentation, the patient died of complications of AIDS.

Abstract
1. The treatment of osteoarthritis is currently purely symptomatic. To enable rational therapy, careful clinical assessment is necessary to identify the origin of symptoms. Often, effective therapy can result from a biomechanical approach such as surgery, orthotics, physiotherapy and dieting. If drugs are required, there is little evidence that the current over-reliance on non-steroidal anti-inflammatory drugs (NSAIDs) is justified. Full dose regular paracetamol should be the first line of analgesic therapy. In the majority of patients, simple analgesics are probably as effective as NSAIDs. If NSAIDs are used it is necessary to review regularly their use and to be aware of potential toxicity. 2. Many alternative strategies of pain management such as topical preparations, intra-articular steroid injections, acupuncture, radiosynovectomy, transcutaneous nerve stimulation and anti-depressants, may be effective but their precise place in the armamentarium is not yet fully established. 3. The realisation that osteoarthritis is not a passive 'wear and tear' phenomenon but an active process that may be potentially modified, has led to interest in 'chondroprotective' agents, which may beneficially affect the osteoarthritic process. To date there are no convincing data available that such agents are, in fact, chondroprotective in humans.

Abstract
There is a strong feeling that despite the increasing awareness of their adverse effects, non-steroidal anti-inflammatory drugs (NSAIDs) are not always used appropriately. To examine this problem amongst elderly patients who may be at particular risk, 500 acute admissions to Health Care of the Elderly wards were studied prospectively. Sixty-five patients were currently receiving NSAIDs; 56 had medical conditions possibly caused by, or aggravated by NSAIDs. Indications for NSAIDs were often no longer apparent, and these drugs were successfully discontinued in 56; in 22 no alternative therapy was required. Importantly, following discharge the majority of patients remained off NSAIDs. These data support the need for continual review of NSAID requirements and regular monitoring for adverse effects, particularly in this high risk group.

Abstract
The value of scalp cooling in the prevention of alopecia was investigated in 32 patients with advanced breast cancer who were given a mean of four courses of 40-80 mg/m2 of epirubicin. None of the 15 patients free from liver metastases who received scalp cooling required a wig, whereas four of eight similar patients who did not receive scalp cooling did require a wig. Abnormalities of aspartate transaminase and alkaline phosphatase pretreatment were predictive for reduced efficacy of scalp cooling, but not a contraindication to its use.

Abstract
The study investigates the effect of speech therapy on the mood of aphasic stroke patients and their spouses. Patients were randomly allocated to receive speech therapy for 24 weeks starting at 10 weeks post stroke. Patient's mood was measured by means of simple rating scales and an adjective checklist. The mood of relatives was measured by The Goldberg General Health Questionnaire and The Wakefield Depression Inventory. Whereas depression and anxiety were surprisingly uncommon in aphasic patients, many spouses suffered depression and minor psychiatric disturbances. There were no significant differences between treated and untreated patients and their spouses on any measure. Speech therapy was not shown to have any psychological benefits.

Abstract
Four human ovarian carcinoma xenografts were established and maintained in immune-suppressed mice. Cells obtained from these xenografts were exposed in vitro to melphalan, JM8, and cisplatin; cell survival following a 1-h exposure was measured using a soft-agar colony assay. A similar dose-response curve was obtained with melphalan for each of the four xenografts, despite previous treatment with an alkylating agent in two of the patients from whom the xenografts originated. Cell survival was also compared after JM8 and cisplatin exposure in each individual xenograft. It was found to be similar for each tumour when the concentrations of JM8 used were 10-fold greater than those of cisplatin. Early clinical studies in which JM8 has been shown to be effective in the treatment of ovarian carcinoma support the view that xenograft tumours may have a role in phase-II screening of new cytotoxic agents.

Aphasic stroke patients were randomly allocated to either a speech therapy group receiving treatment twice a week for 24 weeks or a no-treatment control group. Patients in both groups improved and there were no significant differences in language recovery between the 104 patients allocated to the treatment group and the 87 allocated to the no-treatment group. This treatment regimen, which is representative of clinical practice, is ineffective for most aphasic stroke patients.

Abstract
Tumour cells from 7 patients with ovarian carcinoma and from 22 different human tumour xenografts representing a wide range of histological sub-types have been examined for multicellular spheroid forming ability. Spheroid formation was limited to cells derived from xenografts. Of the 22 lines tested, 5 formed spheroids capable of growth in isolation. There was no clear relationship between histological type and spheroid-forming ability. The plating efficiency of tumour cells obtained from spheroids was always greater than for the cells obtained from the dissociated tumour of origin and was in some cases as much as 6-fold greater. Spheroid growth was nearly exponential for 4 cell lines. Volume growth delay was used to investigate the activity of melphalan, adriamycin, the Vinca alkaloids, CCNU and cisplatin. Differences between lines in drug response broadly reflected patient and in vivo xenograft response.

Abstract
cis-Diammine-1,1-cyclobutane dicarboxylate platinum II (CBDCA, JM8), an analogue of cisplatin showing reduced toxicity in preclinical studies, was evaluated in 60 patients. Doses were given initially every 3 weeks and escalated from 20 to 520 mg/m2. Following this, doses were given every 4 weeks and escalated from 300 to 500 mg/m2. The dose-limiting toxicity, thrombocytopoenia, occurred in four-fifths of patients treated at 520 mg/m2, with the nadir occurring 3 weeks after treatment. Leucopoenia and anaemia also occurred but were less severe. Vomiting occurred in all patients receiving over 120 mg/m2 but seldom persisted beyond 24 h. Serial measurements of 51Cr-EDTA clearances, urinary N-acetylglucosaminidase, urinary leucine aminopeptidase, and beta 2-microglobulin did not reveal significant evidence of nephrotoxicity. Detriment to the audiogram has not been seen in the first 13 patients studied. Pharmacological studies showed that most of the dose of platinum was excreted in the urine, and that impairment of renal function may be associated with drug retention and an increased risk of myelosuppression. The previous therapy and age of the patient also affected the tolerance of the drug. Clinical responses were seen in patients with ovarian carcinoma receiving greater than 120 mg/m2. A further dose escalation was performed on a 4-week schedule in patients under 65 with good renal function. The maximum dose it was possible to administer repeatedly without incurring myelosuppression was in the range 400-500 mg/m2. JM8 is not significantly nephrotoxic and is less emetic than cisplatin. It has antitumour activity in man and deserves wider evaluation, along with the other analogues under study in various centres, as an alternative to cisplatin.

Abstract
To evaluate potential factors affecting reproductive performance, 6 monkeys of Colombian and 6 of Bolivian origin, housed as mated pairs, were observed via closed circuit television and a remote-controlled camera. Behavioural differences in feeding and drinking, locomotor activity, environmental interaction, positive social interaction, autogrooming, nestbox occupancy, and playing were observed. The differences noted indicate that the subspecies may have different social structures.
