Utility of a simplified ultrasonography scoring system among patients with rheumatoid arthritis: A multicenter cohort study

We aimed to evaluate the utility of a simplified ultrasonography (US) scoring system, which is desired in daily clinical practice, among patients with rheumatoid arthritis (RA) receiving biological/targeted synthetic disease-modifying antirheumatic drugs (DMARDs).A total of 289 Japanese patients with RA who were started on tumor necrosis factor inhibitors, abatacept, tocilizumab, or Janus kinase inhibitors between June 2013 and April 2019 at one of the 15 participating rheumatology centers were reviewed. We performed US assessment of articular synovia over 22 joints among bilateral wrist and finger joints, and the 22-joint (22j)-GS and 22-joint (22j)-PD scores were evaluated as an indicator of US activity using the sum of the GS and PD scores, respectively.The top 6 most affected joints included the bilateral wrist and second/third metacarpophalangeal joints. Therefore, 6-joint (6j)-GS and -PD scores were defined as the sum of the GS and PD scores from the 6 synovial sites over the aforementioned 6 joints, respectively. Although the 22j- or 6j-US scores were significantly correlated with DAS28-ESR or -CRP scores, the correlations were weak. Conversely, 6j-US scores were significantly and strongly correlated with 22j-US scores not only at baseline but also after therapy initiation.Using a multicenter cohort data, our results indicated that a simplified US scoring system could be adequately tolerated during any disease course among patients with RA receiving biological/targeted synthetic DMARDs.     

Effects of functional movement screen training in high-school baseball players: A randomized controlled clinical trial

Background:In recent years, the functional movement screen (FMS) and FMS training have attracted attention as a means of preventing injury, but no studies have examined the effect of such training in high-school baseball players. The aim of this study was to clarify the effect of FMS training on FMS score, physical function and baseball performance in high-school baseball players.Methods:Subjects in this randomized controlled clinical trial were high-school male baseball players assigned to either an FMS training group (intervention group) or a control group. The intervention group performed FMS training 4 times per week for 12 weeks. FMS ability, physical function, and baseball performance were measured prior to the intervention, 8, 12, and 24 weeks after the intervention in the subjects’ school environment.Results:A total of 71 baseball players aged 15 to 17 years were recruited and assigned to either an intervention group (n = 37) or control group (n = 34). There was no significant difference in the characteristics of participants between the 2 groups. Most FMS scores improved to 12 weeks after continued training. In the intervention group compared with the control group, deep squat, hurdle step, inline lunge, active straight leg raise, trunk stability push-up and rotary stability FMS score, total FMS score and eyes closed single leg stance time significantly increased after 8 weeks of training. While hurdle step, inline lunge, active straight leg raise, trunk stability push-up, total FMS score, and eyes closed single leg stance time significantly increased, pitching ball speed significantly decreased at the end of the 12 week training period. Eyes closed single leg stance time and feeling of fatigue significantly improved 12 weeks after training. The number of subjects who scored less than 14 for the total FMS score in the intervention group compared with control group were significantly less after 8 and 12 weeks of FMS training.Conclusion:FMS training for 8 weeks contributes to improving FMS scores for high-school baseball players, but FMS scores go down if FMS training is not continued.Trial registration:University Hospital Medical Information Network Center, Tokyo, Japan: UMIN000027553.

Effect of cilostazol on restenosis after coronary angioplasty and stenting in comparison to conventional coronary artery stenting with ticlopidine

BACKGROUND: The role of antiplatelet therapy with ticlopidine plus aspirin in the prevention of subacute thrombosis after coronary artery stenting has been established. However, restenosis remains a major limitation in coronary artery stenting. METHODS: To compare the effect of cilostazol on restenosis after coronary angioplasty and stenting with that of ticlopidine after coronary artery stenting, 213 patients with 230 lesions who underwent successful coronary interventions were evaluated. Optimal results (residual stenosis less than 30%) were obtained by balloon angioplasty in 112 lesions, 64 lesions were treated with aspirin 81 mg/day (balloon-aspirin group) and 48 lesions with cilostazol 200 mg/day and aspirin 81 mg/day (balloon-cilostazol group). Stent implantation was performed in the remaining 118 lesions; 55 lesions were treated with ticlopidine 200 mg/day and aspirin 243 mg/day (stent-ticlopidine group) and 63 lesions with cilostazol 200 mg/day and aspirin 81 mg/day (stent-cilostazol group). Concomitant medications were continued for 4 to 6 months of follow-up. RESULTS: No adverse events including acute occlusion and subacute thrombosis occurred in any groups. Although immediate gain and minimal lumen diameter immediately after angioplasty were significantly larger in stent groups than those in balloon groups, net gain at follow-up was significantly larger in cilostazol groups (1.54+/-0.83 mm in balloon-cilostazol group and 1.65+/-0.78 mm in stent-cilostazol group) than other groups (1.02+/-0.81 mm in balloon-aspirin group and 1.21+/-0.70 in stent-ticlopidine group) as a result of significantly lower late loss and loss index in cilostazol groups. The restenosis rate was significantly lower in cilostazol groups (12.5% in balloon-cilostazol group and 14.3% in stent-cilostazol group) than other groups (43.8% in balloon-aspirin group and 32.7% in stent-ticlopidine group). The rate of recurrent angina was significantly lower in cilostazol groups (4.3% in balloon-cilostazol group and 1.9% in stent-cilostazol group) than in other groups (17.5% in balloon-aspirin group and 14.0% in stent-ticlopidine groups). CONCLUSIONS: Both optimal balloon angioplasty with cilostazol and coronary artery stenting with cilostazol have a potential to reduce restenosis compared with optimal balloon angioplasty with aspirin or conventional coronary artery stenting with ticlopidine plus aspirin.     

Spontaneous improvement in a pediatric patient with peripheral T‐cell lymphoma

Peripheral T‐cell lymphoma (PTCL) is rare in children, and it has a poor prognosis compared with other types of lymphoma. We report the case of a 7‐year‐old boy with spontaneous improvement of PTCL complicated by hemophagocytic syndrome as the initial symptom. He complained of pain and swelling of the right neck and presented with high fever. Pancytopenia, liver dysfunction, elevated ferritin and soluble interleukin 2 receptor were noted on laboratory tests. Peripheral blood plasma and white blood cells were positive for Epstein–Barr virus (EBV) genome but, after several days, the fever abated and laboratory data improved. On histopathology of lymph node biopsy, he was diagnosed as having PTCL not otherwise specified (PTCL‐NOS) with EBV infection. He received no chemotherapy and was disease free at the last follow up, 6 years 8 months after onset. This is probably the first case of spontaneous improvement in PTCL‐NOS. Careful treatment planning is therefore necessary in PTCL‐NOS, given the possibility of spontaneous improvement of symptoms.     

A case of synchronous primary lung cancer with hamartoma]

We present a case of a synchronous primary lung cancer adjacent to a hamartoma. In a 48-year-old man, a nodular shadow was found in the right middle lung field in 1990, and had grown slowly for 10 years. Another mass shadow was detected in the right upper lung field in 2000. The patient was admitted to our hospital for further examination of these abnormal shadows. Bronchoscopic examination revealed, in the right upper lobe, a poorly differentiated adenocarcinoma of clinical stage IIIB. Neoadjuvant chemotherapy followed by pneumonectomy was performed. The microscopic findings for the tumor resected from the right S2 showed poorly differentiated adenocarcinoma and those for the other, in the right S3, showed chondromatous hamartoma. Some 50 reports of lung cancer in parents with a chondromatous hamartoma have appeared in the literature. Most of these cases have some common features as follows: 1) men past middle age, 2) adenocarcinoma, and 3) lung cancer and chondromatous hamartoma present in the same lobe. The present case had all of these features, and may assist in the understanding of the process of development of lung cancer adjacent to a hamartoma.     

Clinicopathologic features and prognostic factors of resected solitary small-sized hepatocellular carcinoma

BACKGROUND/AIMS: Solitary small-sized HCCs tend to be considered as less aggressive cancer, and non-surgical treatments have recently been preferred. The aim of this study was to clarify the clinicopathological features and the prognostic factors of small-sized HCCs and to evaluate the significance of hepatic resection for them. METHODOLOGY: Eighty patients with HCC up to 2cm in diameter who had undergone hepatic resection were enrolled in this study. We investigated the clinicopathological features and evaluated the prognostic factors by univariate and multivariate analyses. RESULTS: The overall survival rates at 3, 5 and 10 years were 83%, 69% and 36%, respectively, and the corresponding disease-free survival rates were 63%, 41% and 10%. Well-differentiated, moderately differentiated and poorly differentiated HCC were detected in 29%, 65% and 6% of the patients, respectively. Furthermore, microscopic portal vein invasion (vp), hepatic vein invasion (vv) and intrahepatic metastasis (im) were positive in 15%, 4% and 10% of the patients, respectively. Multivariate analysis revealed that Child-Pugh classification (p=0.005) and vp (p=0.0008) were independent prognostic factors for survival rate and that platelet count (p=0.002) and tumor differentiation (p=0.0016) were independent prognostic factors for disease-free survival rate. CONCLUSIONS: Even solitary small-sized (up to 2cm in diameter) HCC already have the characteristics of advanced HCC. When hepatic function is well preserved, hepatic resection should be the first choice for local control, especially in cases of moderately to poorly differentiated HCC, because the frequency of microscopic vascular invasion is high.     

Left atrial thrombus causing pulmonary embolism by passing through an atrial septal defect.

A 66-year-old woman admitted with dyspnea on exertion had atrial fibrillation and left ventricular dysfunction. Echocardiography revealed an atrial septal defect (ASD) and a soft, easily deformable thrombus in the dilated left atrium. The atrial mass suddenly disappeared on the 10th day after admission, and contrast-enhanced chest computed tomography and pulmonary blood flow scintigraphy showed that the thrombus had detached from the left atrium, floated into the right atrium through the ASD and caused pulmonary embolism. This is the first documented case of a left atrial thrombus causing pulmonary embolism by passing through an ASD. When an ASD is present, it is important to consider not only paradoxical thromboembolism (from the right to the left atrium), but also pulmonary embolism caused by thromboembolism from the left to the right atrium.     

Protein C activation in NIDDM patients

Summary Enhanced activation of the clotting system has been recently implicated in the pathogenesis of vascular complications in patients with diabetes mellitus. Abnormalities of the anticoagulant system may constitute a potential trigger factor for the haemostatic activation observed in diabetic subjects. The current study aimed to evaluate anticoagulant activity in diabetic patients by assessing the plasma levels of activated protein C-protein C inhibitor complex; and by measuring the anticoagulant response to exogenous thrombomodulin. This study comprised 61 patients (34 men, 27 women) with non-insulin-dependent diabetes mellitus (NIDDM) of whom 22 showed microalbuminuria and 39 normoalbuminuria. Data obtained in 31 non-obese and non-diabetic subjects were available for comparison. The plasma levels of fibrinogen (p < 0.02), prothrombin fragment 1 + 2 (p < 0.05), fibrin monomer (p < 0.0001), protein C antigen (p < 0.005), total protein S antigen (p < 0.02), soluble thrombomodulin (p < 0.005) and soluble E-selectin (p < 0.005) were significantly higher in diabetic patients than in healthy subjects. The plasma level of activated protein C-protein C inhibitor complex (7.4 ± 3.8 vs 3.0 ± 0.4 pmol/l) was significantly higher (p < 0.0001) and the anticoagulant response to exogenous thrombomodulin (23.4 ± 2.6 vs 35.3 ± 3.0 ng/ml) was markedly lower (p = 0.005) in all diabetic patients than in healthy subjects. Cases with microalbuminuria presented low plasma levels of activated protein C-protein C inhibitor complex (5.5 ± 0.6 vs 8.6 ± 0.7 pmol/l, p < 0.05) and significantly decreased values of the anticoagulant response to exogenous thrombomodulin (16.5 ± 2.9 vs 23.4 ± 2.6 %, p = 0.03) as compared to those with normoalbuminuria. The present study suggests that the hyper-coagulable state in NIDDM is associated with an increased activation of protein C but with a poor plasma reactivity to the anticoagulant effect of thrombomodulin.
