RESUMEN
OBJECTIVES: Differentiation between polymyalgia rheumatica (PMR) and elderly-onset rheumatoid arthritis (EORA), especially in elderly patients, is often difficult due to similarities in symptoms and serological kinetics. In this study, we aimed to analyse the predictors of EORA with PMR-like onset. METHODS: Seventy-two patients diagnosed with PMR, who attended our hospital for routine care and underwent musculoskeletal ultrasonography at that time were evaluated. Synovitis was evaluated semi-quantitatively (0-3) by grey scale (GS) and power Doppler (PD) in 24 joints [both hands (wrist, metacarpophalageal, and proximal interphalangeal joints) and both shoulder joints]. RESULTS: Overall, 18 patients had rheumatoid arthritis (25.0%); the mean age was 75.0 years, and 34.7% and 65.3% were male and female, respectively. In PMR and PMR/EORA groups, multivariate logistic analysis showed that rheumatoid factor positivity, GS ≥2 of hand joints, and PD ≥1 of hand joints were independent factors with significant differences. At least one of the three factors had a sensitivity of 88.9% and specificity of 92.6%. CONCLUSIONS: The presence of at least one of the criteria: rheumatoid factor positivity, GS ≥ 2, and PD ≥ 1 of hand joints, suggested the possibility of developing EORA within 1 year of PMR diagnosis.

The Japanese Guidelines for management of acute cholangitis and cholecystitis were published in 2005 as the first practical guidelines presenting diagnostic and severity assessment criteria for these diseases. After the Japanese version, the Tokyo Guidelines (TG07) were reported in 2007 as the first international practical guidelines. There were some differences between the two guidelines, and some weak points in TG07 were pointed out, such as low sensitivity for diagnosis and the presence of divergence between severity assessment and clinical judgment for acute cholangitis. Therefore, revisions were started to not only make them up to date but also concurrent with the same diagnostic and severity assessment criteria. The Revision Committee for the revision of TG07 (TGRC) performed validation studies of TG07 and new diagnostic and severity assessment criteria of acute cholangitis and cholecystitis. These were retrospective multi-institutional studies that collected cases of acute cholangitis, cholecystitis, and non-inflammatory biliary disease. TGRC held 35 meetings as well as international email exchanges with co-authors abroad and held three International Meetings. Through these efforts, TG13 improved the diagnostic sensitivity for acute cholangitis and cholecystitis, and presented criteria with extremely low false positive rates. Furthermore, severity assessment criteria adapted for clinical use, flowcharts, and many new diagnostic and therapeutic modalities were presented. The world's first management bundles of acute cholangitis and cholecystitis were also presented. The revised Japanese version was published with the same content as TG13. An electronic application of TG13 that can help to diagnose and assess the severity of these diseases using the criteria of TG13 was made for free download.

BACKGROUND: Improvements in the treatment of rheumatoid arthritis (RA) have made it possible to achieve treatment goals. It has been reported that both residual synovitis caused by RA and the patients' subjective symptoms remain even after achieving the treatment goals; however, there are limited reports showing a relationship between them. Furthermore, no studies have evaluated the relationship between patient-reported outcomes (PROs) and subclinical synovitis measured by musculoskeletal ultrasonography (MSUS) in the treatment of RA. This study aimed to investigate residual symptoms and residual synovitis due to remission (REM) or low disease activity (LDA). METHODS: We performed MSUS on 300 patients with RA who attended our hospital for routine care, and we analysed them cross-sectionally by disease activity. Grayscale (GS) and power Doppler (PD) synovitis was evaluated in 22 bilateral hand joints using MSUS. We first performed univariate and multivariate analysis by dividing the data by disease activity. Next, we analysed each PRO in the obtained MSUS results. RESULTS: A multivariate analysis of high disease activity (HDA)/moderate disease activity (MDA) vs. LDA/ REM group identified tender joint count (TJC), pain visual analog scale (VAS) score, and presence or absence of GS score ≥ 2. The one-way analysis of the relationship between the presence or absence of GS score ≥ 2 and each PRO showed a significant difference. In contrast, a multivariate analysis of LDA vs. REM group identified TJC and fatigue VAS score. In REM, PROs alone were relevant, and there was no correlation with MSUS. CONCLUSION: We found that the residual inflammation in the ultrasound images was associated with PROs in the LDA group, but not in the REM group. Trial registration Retrospectively registered.
RESUMEN
Baricitinib is a Janus kinase 1/2 (JAK1/2) inhibitor used in the treatment of rheumatoid arthritis. A 71-year-old woman with rheumatoid arthritis complicated by systemic sclerosis and type 1 diabetes that were resistant to multiple disease-modifying antirheumatic drugs started treatment with baricitinib. After baricitinib administration, the disease activity of her rheumatoid arthritis was attenuated from the early stage of treatment, and the effect was maintained for up to 52 weeks. In addition, the skin sclerosis in systemic sclerosis showed an improvement. Regarding the influence on type 1 diabetes, the required daily dose of insulin and hemoglobin A1c (HbA1c) levels decreased. To date, no studies have demonstrated the effectiveness of baricitinib on systemic sclerosis or type 1 diabetes. We report that baricitinib was effective for systemic sclerosis and type 1 diabetes, as well as for rheumatoid arthritis, for up to 52 weeks.
RESUMEN
Case: An 88-year-old female with Alzheimer's-type dementia who mis-swallowed a press-through package visited our emergency department. Outcome: Plain radiography detected no foreign bodies, whereas plain computed tomography showed an elliptical body with a high density in the lower esophagus. The press-through package containing a tablet in the esophagogastric junction was successfully removed without severe complications using the endoscopic protector hood. In cases of press-through package mis-swallowing, it is important for emergency physicians to make an early and correct diagnosis of the location of the package, which shows high radiolucency. Based on the results of this case, we hypothesize that carrying out early computed tomography examinations is useful for identifying swallowed press-through packages. Our retrospective investigation showed that computed tomography has a sensitivity of 100% for detecting press-through packages. Conclusion: We experienced a case of press-through package mis-swallowing diagnosed on computed tomography. We recommend performing computed tomography examinations, especially in patients with an uncertain history and unclear symptoms.
RESUMEN
The locus coeruleus (LC) is a noradrenergic brainstem structure that is considered to play a role in promoting arousal. To further clarify the role of LC noradrenergic neurons, we performed an optogenetic assay by injecting AAV-channelrhodopsin-2 (ChR2) into the LC of cre-tyrosine hydrolase (TH) mice. We found here that the specific activation of LC noradrenergic neurons produced a significant increase in wakefulness and a significant decrease in non-rapid eye movement (NREM) sleep during photostimulation. On the other hand, neuropathic pain is believed to significantly interfere with sleep, and inadequate sleep may contribute to the stressful negative consequences of living with pain. In the present study, sciatic nerve ligation, which produced significant thermal hyperalgesia, significantly increased the levels of noradrenaline released in the prefrontal cortex (PFC) by the weak electrical stimulation of neurons in the LC. Under these conditions, the systemic administration of adrenaline α and ß inhibitor cocktail at 7 days after sciatic nerve ligation restored the increased wakefulness and decreased NREM sleep to normal levels. These results suggest that neuropathic pain may accelerate neurons in the LC, and its overactivation may be, at least in part, associated with sleep disturbance under neuropathic pain.
