RESUMEN
INTRODUCTION: Flexor tenosynovitis (FTS) is a deep space infection of an upper extremity digit which carries a high rate of morbidity. OBJECTIVE: This review highlights the pearls and pitfalls of FTS, including presentation, diagnosis, and management in the emergency department (ED) based on current evidence. DISCUSSION: FTS typically occurs after direct penetrating trauma to the volar aspect of an upper extremity digit. Development of a deep space infection that quickly propagates through the flexor tendon sheath of a digit can result in serious structural damage to the hand and place the patient at risk for significant morbidity such as finger amputation or even result in death. Signs of FTS include symmetrical swelling of the affected finger, the affected finger being held in a flexed position, pain on any attempt of passive finger extension, and tenderness along the course of flexor tendon sheath, known as the Kanavel signs. Systemic symptoms such as fevers and chills may occur. Recognition of these signs and symptoms is paramount in diagnosis of FTS, as laboratory and imaging assessment is not typically diagnostic. ED management involves intravenous antibiotics and emergent surgical specialist consultation. CONCLUSION: An understanding of the presentation and risk factors for development of FTS can assist emergency clinicians in diagnosing and managing this disease in an expedited fashion.

OBJECTIVE: This study is a sub-analysis from the patient cohort of the STARTER (Sonographic Tenosynovitis Assessment in RheumaToid arthritis patiEnts in Remission) study. The aim was to evaluate differences in ultrasound-detected joint and/or tendon involvement between patients receiving therapies based on a combination of conventional synthetic DMARDs (csDMARDs) and biologic DMARDs (bDMARDs) and those who were treated with either csDMARDs or bDMARDs in monotherapy. MATERIAL AND METHODS: Four hundred and twenty-seven consecutive patients with a diagnosis of RA were recruited between October 2013 and June 2014. They were divided into three subgroups based on their therapy at baseline: patients with bDMARD in monotherapy, patients with csDMARD in monotherapy and patients in combination therapy (csDMARD + bDMARD). At baseline, 6 months and 12 months, a clinical examination (28 joint count) and an ultrasound evaluation were performed in each patient. A score of grey-scale (GS) and power Doppler (PD) synovitis and tenosynovitis was calculated based on the OMERACT scoring systems. RESULTS: Two hundred and fifty-six patients completed the observation period: 48 patients from the bDMARD group (18.75%), 152 patients from the csDMARD group (59.38%) and 56 patients from csDMARD + bDMARD group (21.88%). The analysis showed that GS tenosynovitis and PD tenosynovitis are better controlled in combination therapy than they are with csDMARD alone (P = 0.025 and P = 0.047, respectively); for PD synovitis, there was a better response in those who were treated with the combination therapy when compared with the patients receiving csDMARD (P = 0.01) or bDMARD (P = 0.02) alone. CONCLUSIONS: The analysis showed a lower prevalence of subclinical inflammatory manifestations detected with ultrasound imaging in those patients treated with the combination therapy than in those in monotherapy.

OBJECTIVES: This study aimed to determine the prevalence of ultrasound-detected tendon abnormalities in healthy subjects (HS) across the age range. METHODS: Adult HS (age 18-80 years) were recruited in 23 international Outcome Measures in Rheumatology ultrasound centres and were clinically assessed to exclude inflammatory diseases or overt osteoarthritis before undergoing a bilateral ultrasound examination of digit flexors (DFs) 1-5 and extensor carpi ulnaris (ECU) tendons to detect the presence of tenosynovial hypertrophy (TSH), tenosynovial power Doppler (TPD) and tenosynovial effusion (TEF), usually considered ultrasound signs of inflammatory diseases. A comparison cohort of patients with rheumatoid arthritis (RA) was taken from the Birmingham Early Arthritis early arthritis inception cohort. RESULTS: 939 HS and 144 patients with RA were included. The majority of HS (85%) had grade 0 for TSH, TPD and TEF in all DF and ECU tendons examined. There was a statistically significant difference in the proportion of TSH and TPD involvement between HS and subjects with RA (HS vs RA p<0.001). In HS, there was no difference in the presence of ultrasound abnormalities between age groups. CONCLUSIONS: Ultrasound-detected TSH and TPD abnormalities are rare in HS and can be regarded as markers of active inflammatory disease, especially in newly presenting RA.

OBJECTIVES: We aimed to investigate the prevalence of US findings in the hand joints and related tendons and explore clinical and laboratory associations in SLE patients of the typical lupus clinic. METHODS: One hundred consecutive SLE patients were enrolled in the study. Using B-mode and Doppler US, bilateral wrist, metacarpophalangeal and proximal interphalangeal joints were examined for synovitis and erosions, as well as for signs of hand tenosynovitis. RESULTS: US detected synovitis (grade 1-3) in 75% and erosive changes in 25% of the cohort. We found that clinical examination underestimated grade ≥2 synovitis by 13%, while US detected SH grade ≥2 in 10% of asymptomatic patients. The overall inflammatory burden, reflected by the US score, was associated with disease activity (respectively with CPR, SELENA-2K, MS-BILAG, and hypocomplementemia), as well as the presence of bone erosions. Rhupus patients had higher inflammatory markers, significantly more synovial hypertrophy, more erosions, more grade 3 tenosynovitis, and were more likely to receive methotrexate (p<0.001) than patients with SLE arthritis, while patients with Jaccoud's arthropathy were more likely to accumulate damage. The dominant hand exhibited more inflammatory changes (respectively synovial hypertrophy grade ≥2) at both the wrist and MCP joints; however, handedness was not associated with structural damage. CONCLUSIONS: In conclusion: 1. joint involvement in SLE is frequent and underacknowledged; 2. the overall inflammatory burden is associated with systemic disease activity and joint damage; (3) destructive arthritis is more likely to occur in the context of concomitant RA or within an "RA-like" subtype of SLE arthropathy; 4. hand dominance is associated with synovitis, but not structural changes; 5. US assessment may help tailor the management of joint involvement, thus preventing joint damage and disability in SLE patients.

PURPOSE: We hypothesized that repeat injections are associated with a decreased rate of success and that the success rate of injections correlates with patient comorbidities. METHODS: Using a commercially available insurance database, patients diagnosed with De Quervain tenosynovitis were identified using International Classification of Diseases, Ninth Revision and Tenth Revision codes and stratified by therapeutic interventions, including therapy, injections, and surgery, as well as comorbidities. Injection failure was defined as a patient receiving a repeat injection or subsequent surgical management. Success was defined as no further therapies identified after an intervention. RESULTS: From 2007 to 2017, 33,420 patients with a primary diagnosis of De Quervain tenosynovitis were identified. Women represented 77.5% (25,908) of the total and were 2.6 times more likely to be diagnosed than men. Black patients were more likely to be diagnosed than White patients. Black and White women were found to have the highest incidence (relative risk 3.4 and 2.3, respectively, compared with White men). Age was also significantly correlated with an increased risk of diagnosis of the condition, with a peak incidence at the age of 40-59 years (relative risk, 10.6). Diabetes, rheumatoid arthritis, lupus, and hypothyroidism were associated with an increased risk of diagnosis. Overall, 53.3% of the patients were treated with injections, 11.6% underwent surgery, and 5.2% underwent therapy. Treatment with a single injection was successful in 71.9% of the patients, with 19.7% receiving a repeat injection and 8.4% treated with surgery. The overall success rate of subsequent injections was 66.3% for the second injection and 60.5% for the third. The initial injection had a higher rate of success in diabetics than in nondiabetics; however, the difference (2%) was not clinically relevant. CONCLUSIONS: Although the success rate for the treatment of De Quervains tenosynovitis decreases with multiple injections, repeat injections have a high rate of success and are a viable clinical option. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

BACKGROUND: Nontuberculous mycobacteria (NTM) are a rare cause of infectious tenosynovitis of the upper extremity. Using molecular methods, clinical microbiology laboratories are increasingly reporting identification down to the species level. Improved methods for speciation are revealing new insights into the clinical and epidemiologic features of rare NTM infections. METHODS: We encountered 3 cases of epidemiologically linked upper extremity NTM tenosynovitis associated with exposure to hurricane-damaged wood. We conducted whole-genome sequencing to assess isolate relatedness followed by a literature review of NTM infections that involved the upper extremity. RESULTS: Despite shared epidemiologic risk, the cases were caused by 3 distinct organisms. Two cases were rare infections caused by closely related but distinct species within the Mycobacterium terrae complex that could not be differentiated by traditional methods. The third case was caused by Mycobacterium intracellulare. An updated literature review that focused on research that used modern molecular speciation methods found that several species within the M. terrae complex are increasingly reported as a cause of upper extremity tenosynovitis, often in association with environmental exposures. CONCLUSIONS: These cases illustrate the importance of molecular methods for speciating phenotypically similar NTM, as well as the limitations of laboratory-based surveillance in detecting point-source outbreaks when the source is environmental and may involve multiple organisms.

Avian reovirus (ARV) is one of the main causes of infectious arthritis/tenosynovitis and malabsorption syndrome (MAS) in poultry. ARVs have been disseminated in Brazilian poultry flocks in the last years. This study aimed to genotype ARVs and to evaluate the molecular evolution of the more frequent ARV lineages detected in Brazilian poultry-producing farms. A total of 100 poultry flocks with clinical signs of tenosynovitis/MAS, from all Brazilian poultry-producing regions were positive for ARV by PCR. Seventeen bird tissues were submitted to cell culture and ARV RNA detection/genotyping by two PCRs. The phylogenetic classification was based on σC gene alignment using a dataset with other Brazilian and worldwide ARVs sequences. ARVs were specifically detected by both PCRs from the 17 cell cultures, and σC gene partial fragments were sequenced. All these sequences were aligned with a total of 451 ARV σC gene data available in GenBank. Phylogenetic analysis demonstrated five well-defined clusters that were classified into lineages I, II, III, IV, and V. Three lineages could be further divided into sub-lineages: I (I vaccine, Ia, Ib), II (IIa, IIb, IIc) and IV (IVa and IVb). Brazilian ARVs were from four lineages/sub-lineages: Ib (48.2%), IIb (22.2%), III (3.7%) and V (25.9%). The Bayesian analysis demonstrated that the most frequent sub-lineage Ib emerged in the world around 1968 and it was introduced into Brazil in 2010, with increasing spread soon after. In conclusion, four different ARV lineages are circulating in Brazilian poultry flocks, all associated with clinical diseases. RESEARCH HIGHLIGHTS One-hundred ARV-positive flocks were detected in all main poultry-producing regions from Brazil. A large dataset of 468 S1 sequences was constructed and divided ARVs into five lineages. Four lineages/sub-lineages (Ib, IIb, III and V) were detected in commercial poultry flocks from Brazil. Brazilian lineages shared a low identity with the commercial vaccine lineage (I vaccine). Sub-lineage Ib emerged around 1968 and was introduced into Brazil in 2010.

Avian reoviruses (ARVs) cause arthritis, tenosynovitis, retarded growth, and malabsorption syndrome. After a long time of effective prevention and low rates of viral arthritis/ tenosynovitis in Iran, outbreaks of tenosynovitis in broiler flocks have increased in recent years. Lameness, splay legs, high rate of cull birds, poor performance, uneven birds at harvest, and condemnation at processing cause huge economic losses. In this study, ARVs from the tendons of birds from 23 broiler flocks with marked tenosynovitis were characterized, and their genetic relationship was examined. Analysis of the amino acid sequence of Sigma C protein revealed that all ARVs detected in affected broiler flocks shared genetic homogeneity and this suggests that a single genotype is involved in recent outbreaks. This genotype, so-called "Ardehal strain", is grouped in cluster I with vaccine strains. The amino acid sequence similarity between Ardehal and vaccine strains, including S1133, 1733, and 2408 was less than 80%. As the outbreaks have occurred in progenies of vaccinated flocks, it is proposed here that the difference between vaccine and field strains might contribute to the failure of currently available vaccines to induce protective immunity against Ardehal strain and this led to widespread viral tenosynovitis in Iran.

Psoriatic arthritis (PsA) is an inflammatory arthritis with distinct phenotypic subtypes. Enthesitis is assigned as a hallmark of the disease, given its significant relations to disease activity and quality of life. Our objective is to evaluate the prevalence of enthesitis and its association with some clinical parameters, particularly quality of life, using data from a national registry. Patients with PsA meeting ClASsification criteria for Psoriatic Arthritis (CASPAR) were enrolled by means of a multi-centre Turkish League Against Rheumatism (TLAR) Network Project. The following information was recorded in web-based case report forms: demographic, clinical and radiographic data; physical examination findings, including tender and swollen joint counts (TJC and SJC); nail and skin involvement; Disease Activity Score-28 for Rheumatoid Arthritis with Erythrocyte Sedimentation Rate (DAS 28-ESR); Bath Ankylosing Spondylitis Disease Activity Index (BASDAI); Maastricht Ankylosing Spondylitis Enthesitis Score (MASES); Psoriasis Area Severity Index (PASI); Bath Ankylosing Spondylitis Radiology Index for the spine (BASRI-s); Health Assessment Questionnaire (HAQ); Bath Ankylosing Spondylitis Functional Index (BASFI); Health Assessment Questionnaire for the spondyloarthropathies (HAQ-s); Psoriatic arthritis quality of Life scale (PsAQoL); Short Form 36 (SF-36); Hospital Anxiety Depression Scale (HADS); Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F); and Fibromyalgia Rapid Screening Tool (FiRST) scores. The patients were divided into two groups, namely with and without enthesitis, based on the triple Likert-type physician-reported statement of 'active enthesitis', 'history of enthesitis' or 'none' in the case report forms. Patients with active enthesitis were compared to others in terms of these clinical parameters. A total of 1130 patients were enrolled in this observational study. Of these patients, 251 (22.2%) had active enthesitis according to the clinical assessment. TJC, HAQ-s, BASDAI, FiRST and PsAQoL were significantly higher whereas the SF-36 scores were lower in patients with enthesitis (p < 0.05). Chronic back pain, dactylitis, and tenosynovitis were more frequent in the enthesopathy group (59.4%/39%, 13.1%/6.5% and 24.7%/3.4%, respectively). Significant positive correlations between the MASES score and the TJC, HAQ, DAS 28-ESR, BASDAI, FiRST and PsAQoL scores, and a negative correlation with the SF-36 score were found. When linear regression analysis was performed, the SF-36 MCS and PCS scores decreased by - 9.740 and - 11.795 units, and the FiRST scores increased by 1.223 units in patients with enthesitis. Enthesitis is an important involvement of PsA with significant relations to quality of life determined with PsAQoL and SF-36 scores. Our study found higher frequency of dactylitis and chronic back pain, and worse quality of life determined with SF-36 and PsAQoL scores in patients with enthesitis.

OBJECTIVE: To define the role of ultrasound (US) for the assessment of patients with rheumatoid arthritis (RA) in clinical remission, including joint and tendon evaluation. METHODS: A multicentre longitudinal study has been promoted by the US Study Group of the Italian Society for Rheumatology. 25 Italian centres participated, enrolling consecutive patients with RA in clinical remission. All patients underwent complete clinical assessment (demographic data, disease characteristics, laboratory exams, clinical assessment of 28 joints and patient/physician-reported outcomes) and Power Doppler (PD) US evaluation of wrist, metacarpalphalangeal joints, proximal interphalangeal joints and synovial tendons of the hands and wrists at enrolment, 6 and 12 months. The association between clinical and US variables with flare, disability and radiographic progression was evaluated by univariable and adjusted logistic regression models. RESULTS: 361 patients were enrolled, the mean age was 56.20 (±13.31) years and 261 were women, with a mean disease duration of 9.75 (±8.07) years. In the 12 months follow-up, 98/326 (30.1%) patients presented a disease flare. The concurrent presence of PD positive tenosynovitis and joint synovitis predicted disease flare, with an OR (95% CI) of 2.75 (1.45 to 5.20) in crude analyses and 2.09 (1.06 to 4.13) in adjusted analyses. US variables did not predict the worsening of function or radiographic progression. US was able to predict flare at 12 months but not at 6 months. CONCLUSIONS: PD positivity in tendons and joints is an independent risk factor of flare in patients with RA in clinical remission. Musculoskeletal ultrasound evaluation is a valuable tool to monitor and help decision making in patients with RA in clinical remission.

PURPOSE: To present our experience with culture-positive, nontuberculous mycobacterial infections (NTMI) of the upper extremity and to compare the clinical features and outcomes of treatment among immunocompetent and immunocompromised patients. METHODS: All patients at our medical center diagnosed with NTMI of the upper extremity from December 1, 2000, through December 31, 2015, were included. We performed a retrospective analysis of patient demographic characteristics, delay to diagnosis, risk factors, clinical presentation, specific location, diagnostic testing, treatment regimens, and outcomes. These variables were compared between immunocompetent and immunocompromised patients. RESULTS: Forty-four patients were identified with culture-positive NTMI of the upper extremity. Of the patients, 27 (61%) were men (median age, 59 years [range, 23-83 years]). Twenty (45%) patients were immunocompromised. Immunocompromised patients had fewer known inoculation injuries compared with immunocompetent patients (45% vs 92%). A significant difference existed in the treatment regimens selected for immunocompetent versus immunocompromised patients: immunocompetent patients were more often treated with both antibiotics and surgery (88% vs 50%), whereas immunocompromised patients were more often treated with antibiotics alone (45% vs 4%). Overall, 24% experienced treatment failure and 9% died. Outcomes were relatively similar between immunocompetent and immunocompromised patients. A shorter delay to diagnosis was associated with a lower failure rate. CONCLUSIONS: Diagnosis of upper-extremity NTMI is often delayed because of indolent presentation and lack of clinical suspicion. The clinical presentation, diagnostic delay, and diagnostic testing results are similar between immunocompetent and immunocompromised patients. Although treatment varied significantly between patient groups, outcomes were similar. Timely diagnosis has the greatest impact on patient outcome. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: Diabetes has long been established as a risk factor for hand and forearm infections. The purpose of this study was to review the effect of glycemic factors on outcomes among diabetic patients with surgical upper-extremity infections. We hypothesized that diabetic inpatients may benefit from stronger peri-infection glycemic control. METHODS: A prospective cohort study enrolled diabetic and nondiabetic surgical hand and forearm infections over 3 years. Glycemic factors included baseline glycosylated hemoglobin, blood glucose (BG) at presentation, and inpatient BG. Poor baseline control was defined as glycosylated hemoglobin of 9.0% or greater and poor inpatient control as average BG of 180 mg/dL or greater. The main outcome of interest was the need for repeat therapeutic drainage. Multivariable logistic regression quantified the association between diabetic factors and this outcome. RESULTS: The study involved 322 patients: 76 diabetic and 246 nondiabetic. Diabetic infections were more likely than nondiabetic infections to result from idiopathic mechanisms, occur in the forearm, and present as osteomyelitis, septic arthritis, and necrotizing fasciitis. Diabetic microbiology was more likely polymicrobial and fungal. After first drainage, diabetic patients were more likely to require repeat drainage and undergo eventual amputation. Among diabetic patients, poor inpatient control was associated with need for repeat drainage. CONCLUSIONS: Diabetes exacerbates the burden of surgical upper-extremity infections: specifically, more proximal locations, deeper involved anatomy at presentation, broader pathogenic microbiology, increased need for repeat drainage, and higher risk for amputation. Among diabetic patients, poor inpatient glycemic control is associated with increased need for repeat drainage. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic I.

OBJECTIVES: This study aimed to estimate the prevalence of US-detected tenosynovitis in RA patients in clinical remission and to explore its clinical correlates. METHODS: A total of 427 RA patients in clinical remission were consecutively enrolled from 25 Italian rheumatology centres. Tenosynovitis and synovitis were scored by US grey scale (GS) and power Doppler (PD) semi-quantitative scoring systems at wrist and hand joints. Complete clinical assessment was performed by rheumatologists blinded to the US results. A flare questionnaire was used to assess unstable remission (primary outcome), HAQ for functional disability and radiographic erosions for damage (secondary outcomes). Cross-sectional relationships between the presence of each US finding and outcome variables are presented as odds ratios (ORs) and 95% CIs, both crude and adjusted for pre-specified confounders. RESULTS: The prevalence of tenosynovitis in clinical remission was 52.5% (95% CI 0.48, 0.57) for GS and 22.7% (95% CI 0.19, 0.27) for PD, while the prevalence of synovitis was 71.6% (95% CI 0.67, 0.76) for GS and 42% (95% CI 0.37, 0.47) for PD. Among clinical correlates, PD tenosynovitis associated with lower remission duration and morning stiffness while PD synovitis did not. Only PD tenosynovitis showed a significant association with the flare questionnaire [OR 1.95 (95% CI 1.17, 3.26)]. No cross-sectional associations were found with the HAQ. The presence of radiographic erosions associated with GS and PD synovitis but not with tenosynovitis. CONCLUSIONS: US-detected tenosynovitis is a frequent finding in RA patients in clinical remission and associates with unstable remission.

AIM: The aim of this study was to establish the prevalence of tenosynovitis affecting the interosseous tendons of the hand in a rheumatoid arthritis (RA) population and to assess for association with metacarpophalangeal (MCP) joint synovitis, flexor tendon tenosynovitis or ulnar drift. METHODS: Forty-four patients with RA underwent hand MRI along with 20 normal controls. Coronal 3D T1 VIBE sequences pre- and post-contrast were performed and reconstructed. The presence of interosseous tendon tenosynovitis was recorded alongside MCP joint synovitis, flexor tendon tenosynovitis and ulnar drift. RESULTS: Twenty-one (47.7%) patients with RA showed interosseous tendon tenosynovitis. Fifty-two (14.8%) interosseous tendons showed tenosynovitis amongst the RA patients. Interosseous tendon tenosynovitis was more commonly seen in association with adjacent MCP joint synovitis (p < 0.001), but nine MCP joints (5.1%) showed adjacent interosseous tenosynovitis in the absence of joint synovitis. Interosseous tendon tenosynovitis was more frequently seen in fingers which also showed flexor tendon tenosynovitis (p < 0.001) and in patients with ulnar drift of the fingers (p = 0.01). CONCLUSION: Tenosynovitis of the hand interosseous tendons was found in 47.7% of patients with RA. In the majority of cases this was adjacent to MCP joint synovitis; however, interosseous tendon tenosynovitis was also seen in isolation. KEY POINTS: ⢠Tenosynovitis of the interosseous tendons of the hand occurs in rheumatoid arthritis. ⢠Interosseous tendon tenosynovitis has a prevalence of 47.7% in patients with RA. ⢠Interosseous tendon tenosynovitis is related to MCP joint synovitis in the adjacent joints.

BACKGROUND: It is necessary to develop a safe alternative to isoniazid for tuberculosis prophylaxis in liver transplant recipients. This study was designed to investigate the efficacy and safety of levofloxacin. METHODS: An open-label, prospective, multicenter, randomized study was conducted to compare the efficacy and safety of levofloxacin (500 mg q24h for 9 months) initiated in patients awaiting liver transplantation and isoniazid (300 mg q24h for 9 months) initiated post-transplant when liver function was stabilized. Efficacy was measured by tuberculosis incidence at 18 months after transplantation. All adverse events related to the medication were recorded. RESULTS: CONSORT guidelines were followed in order to present the results. The safety committee suspended the study through a safety analysis when 64 patients had been included (31 in the isoniazid arm and 33 in the levofloxacin arm). The reason for suspension was an unexpected incidence of severe tenosynovitis in the levofloxacin arm (18.2%). Although the clinical course was favorable in all cases, tenosynovitis persisted for 7 weeks in some patients. No patients treated with isoniazid, developed tenosynovitis. Only 32.2% of patients randomized to isoniazid (10/31) and 54.5% of patients randomized to levofloxacin (18/33, P = .094) completed prophylaxis. No patient developed tuberculosis during the study follow-up (median 270 days). CONCLUSIONS: Levofloxacin prophylaxis of tuberculosis in liver transplant candidates is associated with a high incidence of tenosynovitis that limits its potential utility.

A peroneus brevis low-lying muscle belly (LLMB) is a rare anomaly. A few published studies have supported the presence of this anomaly as an etiology for a peroneal tendon tear. However, the association between a peroneus brevis LLMB and tendon subluxation has not been well explored. In the present retrospective study, the magnetic resonance imaging (MRI) and intraoperative findings of 50 consecutive patients undergoing primary peroneal tendon surgery during a 5-year period were assessed. The sensitivity and specificity of MRI compared with the intraoperative findings for identifying peroneal tendon disease were investigated. The presence of associated peroneal tendon pathologic features in patients with and without a peroneus brevis LLMB was also compared. The sensitivity of MRI was high for identifying peroneal tenosynovitis (81.58%) and tear (85.71%). Although the sensitivity of MRI for detecting a peroneus brevis LLMB (3.23%) and tendon subluxation (10.00%) was low, MRI had high specificity at 94.74% and 100%, respectively. Intraoperatively, a peroneus brevis LLMB was seen in 62.00% of the patients with chronic lateral ankle pain and was associated with 64.52% of the patients with tenosynovitis, 29.03% of those with tendon subluxation, and 80.65% of those with a peroneus brevis tendon tear. Although the presence of a peroneus brevis LLMB did not show any statistically significant association with peroneus brevis tendon subluxation, of the 10 patients with intraoperatively observed tendon subluxation, 9 had a concomitant peroneus brevis LLMB. More studies with larger patient populations are needed to better investigate the role of a peroneus brevis LLMB as a mass-occupying lesion resulting in peroneal tendon subluxation.

BACKGROUND: Betel quid chewing is common in Taiwan. The work of betel quid preparers is characterized by long hours of static work, awkward working posture and highly repetitive hand/wrist motion. However, the musculoskeletal health of betel quid preparers receives very little attention. METHODS: The Chinese version of the Standardized Nordic Musculoskeletal Questionnaire (NMQ) was administered, and electrogoniometers and electromyography were used in this cross-sectional study to characterize the hand/wrist motion of the subjects. Physical examinations on the thumbs and wrists of the subjects were conducted by means of Phalen's test and Finkelstein's test, respectively. RESULTS: Among the 225 participants, more than 95% attributed their musculoskeletal complaints to their work, and shoulder, neck, hand/wrist, and lower back discomfort were most frequently reported. More than 70% of the preparers did not seek medical treatment for their musculoskeletal problems. Based on the physical examination, 24% of the participants had suspected symptom of either carpal tunnel syndrome (CTS) or DeQuervain's tenosynovitis. The instrumental measurements indicated that betel quid preparation is characterized by extreme angle ranges and moderate repetition of wrist motion as well as low forceful exertion. CONCLUSIONS: This study concludes that betel quid preparers are a high risk group of developing musculoskeletal disorders (MSDs). Future studies by electrogoniometers and detailed physical examination on betel quid preparers are needed to determine the predisposing factors for CTS. Some intervention measures to prevent MSDs and to lessen psychological stress for this group of workers are strongly suggested.

Bowel-associated dermatosis-arthritis syndrome (BADAS) is a neutrophilic dermatosis, characterized by the occurrence of arthritis and skin lesions related to bowel disease with or without bowel bypass. We report an unusual case of BADAS in a 15-year-old white male with congenital aganglionosis of the colon and hypoganglionosis of the small intestine and multiple bowel surgeries in childhood complicated by short bowel syndrome. He presented with recurrent peripheral polyarthritis, tenosynovitis, and painful erythematous subcutaneous nodules located on the dorsolateral regions of the legs and on the dorsa of the feet. Histological examination disclosed a neutrophilic dermatosis confirming the diagnosis of BADAS.Although an uncommon disease, especially at pediatric age, it is important to evoke the diagnosis of BADAS in children and adolescents with bowel disease, because treatment options and prognosis are distinct from other rheumatologic conditions.

OBJECTIVES: Disseminated gonococcal infections (DGIs) are rare. We describe the characteristics of DGIs in France. METHODS: This is a 3-year retrospective analysis of DGI cases collected through two networks of microbiologists and infectious disease specialists in France between 2009 and 2011. DGI was defined either by the isolation of Neisseria gonorrhoeae from blood and synovial fluid or by the existence of a clinical syndrome consistent with DGI and the isolation of N gonorrhoeae from any site. We describe the epidemiological, clinical and microbiological characteristics and outcomes of DGIs. RESULTS: 21 patients (9 women, 12 men; 18-62 years old) were diagnosed with DGI. The number of DGI cases increased between 2009 and 2011. Two men who had sex with men were coinfected with HIV. We found 28 extragenital locations, including arthritis (14 cases), tenosynovitis (7), skin lesions (4), endocarditis (1), prostatitis (1) and pelvic inflammatory disease (1). Genital signs were present in five patients. The diagnosis was confirmed by cultures in 20 patients-blood (4), synovial fluid (11), genital (3), throat (1), urine (1)-and by molecular biology on a pharyngeal swab in 1 patient. Seven cases were resistant to fluoroquinolones. The patients were treated with ceftriaxone, associated with corticosteroids (two cases) and surgery (six cases). Four patients had joint sequelae. CONCLUSIONS: DGIs are increasing. Men seem to be at higher risk than women. Joint involvement was common. Microbiological diagnosis was based on culture, however molecular biology using pharyngeal swabs was helpful when cultures were negative.

OBJECTIVES: This paper aims to investigate the prevalence and severity of hand and wrist joints power Doppler (PD) ultrasound (US) detected abnormalities in systemic sclerosis (SSc). METHODS: Hand and wrist joints of 46 consecutive SSc patients and 15 healthy controls were studied by using PDUS. Each joint was evaluated for the presence of effusion, synovial hypertrophy, hyperaemia, bone erosions and cortical irregularities; in addition, local tendons for tenosynovitis and hyperaemia, and median nerve for entrapment neuropathy were examined. RESULTS: Synovial hypertrophy was detected in 3% hand joints and in 46% wrists of SSc patients, with significant differences respect to controls (p=0.000004 and 0.000001, respectively). The prevalence of PD positivity was significantly higher in patients' hand joints (1.7%, p=0.001527) and wrists (43%, p=0.000001) than in healthy individuals. Seven percent of hand and 54% of wrist joints resulted to be positive for joint effusion with significant differences from controls (p=0.000001 and p=0.000013, respectively). The prevalence of cortical irregularities was significantly higher (p=0.006) than healthy subjects only at hand joints level. No significant difference was found for bone erosions. Tenosynovitis was found in 6% out of the 1.196 synovial tendon sites examined of SSc patients with significant differences compared to healthy subjects (p=0.000001); PD resulted to be positive in 29% of them, with significantly differences compared to controls (p=0.0038). CONCLUSIONS: This study, focused on hand and wrist joints PDUS assessment of inflammatory and structural abnormalities in SSc, demonstrated a varied and complex involvement both at joint and periarticular tissues level, showing that wrists were more frequently the site of inflammatory findings.
