Addition of the apical oblique projection increases the detection of acute traumatic shoulder abnormalities in adults.

PURPOSE: Plain radiographic evaluation of acute shoulder trauma in adults requires a minimum of two projections, commonly the anteroposterior (AP) and lateral scapular projections, with additional projections taken for diagnosis. The aim of this retrospective study was to determine whether the addition of the apical oblique (AO) projection to the AP and lateral scapular projections increases the number and/or alters the types of abnormalities detected in the examination of acute shoulder trauma. METHODS: Examinations of 56 adults who had undergone three-projection (AP, lateral scapular, AO) radiographic shoulder examination for acute trauma were allocated into two-projection (AP, lateral scapular) and three-projection cases and assessed by a radiologist. The differences in number and types of abnormalities between the two-projection and three-projection cases were quantified using the one-tailed t test and chi-square goodness-of-fit test, respectively. RESULTS: Test-retest reliability was moderate (intra-class correlation coefficient [95%CI], 0.56 [0.15 to 0.80]) for number, and almost perfect (kappa [95%CI], 0.94 [0.85 to 1.00]) for types, of abnormalities detected. There was a significant increase in the number of abnormalities detected across all three-projection versus two-projection cases (difference in means [95%CI], 0.20 [0.01 to 0.39]) and for fractures (difference in means [95%CI], 0.30 [0.11 to 0.49]), but no difference in the types of abnormalities detected (χ 2 = 4.7, p = 0.19). CONCLUSION: This study suggests that adding the AO projection to two-projection examination of acute shoulder trauma increases the number of abnormalities detected; this has potential implications for patient management. Further research investigating differences in types of abnormalities detected between two-projection and three-projection cases is warranted.

Multicentric myofibroblastic sarcoma.

We report a case of synchronous, multicentric low-grade myofibroblastic sarcoma presenting in a 62-year-old man. He initially presented with inflammatory symmetric polyarthritis and adhesive capsulitis of his shoulder and hips bilaterally and did not respond to a trial of disease modifying antirheumatic drugs. Over a period of several years he developed progressive restriction of both knees and nodules on his hands, both knees and back. A biopsy of the nodule on his back was inconclusive and subsequent biopsies on his left and then right knee revealed a spindle cell neoplasm with an infiltrative growth pattern, mitotic figures, positive immunostaining for smooth muscle actin and focal myxoid change consistent with myofibroblastic sarcoma. While myofibroblastic sarcoma has been known to metastasise, to our knowledge, a multifocal presentation of this tumour has not been described previously.

The Apert hand--angiographic planning of a single-stage, 5-digit release for all classes of deformity.

PURPOSE: To demonstrate the utility of computed tomography angiographic planning of a single-stage, complete release of syndactyly in Apert syndrome. METHODS: Computed tomography angiograms were performed as a preoperative planning tool in 6 patients. Five came to surgery. All had a single-stage operation for complete release of their syndactyly. RESULTS: Five patients, ranging from Upton type 1 to type 3 Apert hand deformities, have had preoperative computed tomography angiography that delineated the vascular anatomy. This allowed planning and execution of a single-stage syndactyly release in all patients. The preoperative imaging identified noteworthy abnormalities in vascular anatomy that were incorporated into surgical planning. CONCLUSIONS: The protocol presented allows preoperative planning and single-stage operation for complete release of syndactyly in patients with Apert syndrome.

Response-driven combination therapy with conventional disease-modifying antirheumatic drugs can achieve high response rates in early rheumatoid arthritis with minimal glucocorticoid and nonsteroidal anti-inflammatory drug use.

OBJECTIVES: To assess the safety and efficacy of combination therapy in recent-onset rheumatoid arthritis (RA), with dose adjustments determined by response, in a clinic setting over 3 years. METHODS: Disease-modifying antirheumatic drug (DMARD)-naive patients with RA of median duration of 12 weeks (n = 61) attending an early arthritis clinic were treated with methotrexate, sulfasalazine, hydroxychloroquine, and fish oil. Dosage adjustments and additions of further DMARDs were contingent on response to therapy and tolerance. Outcome measures for efficacy were Disease Activity Score (DAS28), clinical remission, and modified Sharp radiographic score and for safety, adverse events, and DMARD withdrawal. RESULTS: At baseline, subjects had at least moderately active disease (mean +/- SD DAS28 was 5.3 +/- 1.1), impaired function as measured by the modified Health Assessment Questionnaire (mHAQ) (0.9 +/- 0.5), and 37% had bone erosions. By 3 months, 29% were in remission; this increased to 54% at 3 years. The greatest fall in DAS28 and improvement in mHAQ scores occurred in the first 12 months. Erosions were detected in 62% at 3 years. The mean dose of parenteral glucocorticoid was equivalent to 0.1 mg/d of prednisolone. After 3 years, 48% remained on triple therapy; fish oil was consumed by 75% of patients, and 21% used nonsteroidal anti-inflammatory drugs. Gastrointestinal intolerance was the most frequent unwanted event (leading to DMARD withdrawal in 17 patients). Sulfasalazine was most frequently withdrawn (30%). CONCLUSION: This implementation study demonstrates the feasibility, safety, and efficacy of combination therapy with inexpensive DMARDs, fish oil, and minimal glucocorticoid use, in routine clinical practice using predefined rules for dosage adjustment.
