Data about clinical-laboratory features and outcome of antiphospholipid syndrome nephropathy (APSN) in the course of lupus nephritis (LN) are scarce. To determine prevalence, clinical correlations and outcome of APSN in patients with LN, retrospective analysis of renal specimens and review of medical records from 48 LN patients were performed. APSN was found in 12/48 (25 %) of LN. ⋯ APSN-LN and LN did not differ significantly as regards the rate of complete (25 vs. 19.4 %, p = 0.72) and partial treatment response (25 vs. 29 %, p = 0.82) at 6 months and the progression to end-stage renal disease after a median follow-up of 8.1 ± 3.6 years (16.6 vs. 13.8 %, p = 0.82). APSN was demonstrated in a quart of LN, appeared to be independent from underlying LN class and SLE severity, and did not seem to confer a worse prognosis to LN. The findings of higher creatinine and more interstitial fibrosis in APSN should be confirmed in future prospective larger studies.

Randomized Controlled Trial Comparative Study
Efficacy of EMLA cream phonophoresis comparison with ultrasound therapy on myofascial pain syndrome of the trapezius: a single-blind, randomized clinical study.
The aim of this study is to investigate whether eutectic mixture of local anesthetics (EMLA) cream phonophoresis superior to conventional US over the trigger points (TPs) in terms of improvements of pain, range of motion and disability in myofascial pain syndrome (MPS). Fifty patients (42 female, 8 male) diagnosed with MPS were included in the study. Patients were randomly assigned into two treatment groups including phonophoresis (PH) group (n = 25) and ultrasound (US) group (n = 25). ⋯ The NTP decrease in PH group was significantly higher than that in US group (1.84 ± 1.46 vs. 0.72 ± 1.45; p = 0.01). Pain intensity at rest (p = 0.001) and NPDI scores (p = 0.001) were statistically improvement in only PH group. EMLA cream phonophoresis is more effective than conventional ultrasound therapy in terms of pain and associated neck disability, and it seems the complementary treatment option for MPS.

Randomized Controlled Trial
Impact of outpatient clinic ultrasound imaging in the diagnosis and treatment for shoulder impingement: a randomized prospective study.
The use of musculoskeletal ultrasonography (MSUS) in guiding subdeltoid injection has been shown to improve outcome up to 6 weeks in a few small studies. A recent meta-analysis identified the need for further studies with longer-term outcome and larger sample size. This randomized prospective study assessed whether clinic-based MSUS can significantly improve diagnostic accuracy in shoulder pain and whether MSUS-guided shoulder injection results in improved long-term outcomes. ⋯ SFTs, patient VAS and PGA scores for pain improved significantly from baseline in both groups with significantly greater improvements in the MSUS-guided group (44 shoulders) compared to the palpation-guided group (46 shoulders) in all parameters at 6 (p < 0.01) and 12 weeks (p < 0.05). The use of MSUS in guiding subdeltoid injection has been shown to improve outcome up to 6 weeks in a few small studies. A recent meta-analysis identified the need for further studies with longer-term outcome and larger sample size.

Observational Study
Osteoarthritis pain has a significant neuropathic component: an exploratory in vivo patient model.
Osteoarthritis is the most common form of arthritis and includes manifestations of both nociceptive and neuropathic mechanisms. Intravenous lignocaine, a sodium channel blocker and neuronal membrane stabiliser, has been shown in controlled trials to be effective in neuropathic pain; however, the outcome of intravenous lignocaine in osteoarthritis patients has not been assessed yet. The existence of a neuropathic component to the pain of osteoarthritis was investigated by examining possible benefits upon sensory aspects of pain in osteoarthritis patients receiving intravenous lignocaine therapy. ⋯ Pain intensity (p < 0.001), pain relief (p < 0.003) and mobility (p < 0.003) were all significantly improved after administration of lignocaine intravenous infusion therapy. Pain was significantly reduced in a group of osteoarthritis patients after administration of intravenous lignocaine. This suggests that part of the pain mechanism in this patient group may be neuropathic, appears to contribute significantly to the patients' pain, and requires further investigation in studies designed specifically for the purpose.

The aim of this study is to translate, adapt, and validate a Persian version of the Fibromyalgia (FM) Impact Questionnaire (FIQ-P). The FIQ-P was adapted following the translation and back-translation approach; then, it was administered to thirty females with FM. Participants also completed two other validated questionnaires, the Medical Outcome Survey Short Form-36 (SF-36) and the Beck Depression Inventory (BDI). ⋯ Test-retest coefficient ranged from 0.50 for the item "work days missed" to 0.79 for all FIQ-P items. Fair and statistically significant (P < 0.01) correlations were found between the FIQ-P items and two other questionnaires, SF-36 (r = -0.57) and BDI (r = 0.53). We concluded that the FIQ-P is a valid and reliable instrument for measuring health status of Persian-speaking FM patients.
