الوصف: A 56-year-old woman with rheumatoid arthritis who had been taking methotrexate (MTX) for six years visited our hospital with dyspnea and dizziness. Abdominal ultrasonography revealed mild splenomegaly. Laboratory examinations showed a marked elevation in soluble interleukin-2 receptor and lactate dehydrogenase levels. These abnormalities revealed a spontaneous regression after MTX discontinuation, however, they worsened again four months later. Skin biopsies revealed a diagnosis of intravascular large B-cell lymphoma (IVLBCL), and we diagnosed MTX-associated IVLBCL (MTX-IVLBCL) based on its characteristic course. Despite the recurrence of IVLBCL, it showed a good response to chemotherapy. MTX-IVLBCL should therefore be treated with consideration since it has different characteristics from that of de novo IVLBCL.

الوصف: Objective We aimed to clarify clinical and laboratory characteristics of coronavirus disease 2019 (COVID-19) patients, and further explore the features to detect COVID-19 pneumonia at the first visit to community-based hospitals. Methods Diagnoses of COVID-19 were based on positive results from real-time reverse-transcription polymerase chain reaction testing of nasopharyngeal-swab specimens. We retrospectively reviewed the medical records of patients showing positive results. The clinical characteristics and results of blood tests were compared between the patients with and without pneumonia. The risk factors associated with pneumonia were then evaluated by a multivariable analysis. Results The study cohort comprised 154 patients, including 117 patients (76.0%) with pneumonia at first visit. Significant differences were seen in age, the frequency of fever, tachycardia, desaturation (peripheral oxygen saturation ≤95%), any comorbidity, neutrocyte count and fraction, lymphocyte count and fraction, platelet count, lactate dehydrogenase (LDH), C-reactive protein (CRP), and fibrinogen between the patients with and without pneumonia. Using a multivariable analysis, CRP ≥0.3 mg/dL and fibrinogen >400 mg/dL were found to be associated with the presence of pneumonia. Conclusion Community-based settings for screening COVID-19 patients should perform chest X-ray and blood tests for white blood cell fractions, fibrinogen, LDH, and CRP. Of these, elevations in the CRP and fibrinogen levels could be critically associated with the presence of COVID-19 pneumonia.

الوصف: Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a primary intestinal T-cell lymphoma and other organ involvement is very rare. A rare case of MEITL involving the lung and brain is herein reported. The patient developed panperitonitis with a small intestinal perforation, and emergency surgery was performed. The pathological findings from the surgical specimens demonstrated atypical lymphoid cells which were positive for CD3, CD8, and CD56. Moreover, the pathological findings of lung specimens taken by bronchoscopy were consistent with those of the small intestine. It is therefore important to include the possibility of MEITL in the differential diagnosis of cancer patients.

الوصف: Objective We investigated a novel diagnostic scoring system to differentiate Legionella pneumophila pneumonia from Streptococcus pneumoniae pneumonia. Methods We retrospectively reviewed the clinical data of 62 patients with L. pneumophila pneumonia (L-group) and 70 patients with S. pneumoniae pneumonia (S-group). Results The serum sodium (Na) levels tended to be lower according to the severity [age, dehydration, respiratory failure, orientation disturbance, low blood pressure (A-DROP)] score in the L-group. On a multivariate analysis, we found that four factors were independent predictive markers for inclusion in the L-group: relative bradycardia [hazard ratio (HR) 5.177, 95% confidence interval (CI): 1.072-24.993, p=0.041], lactate dehydrogenase (LDH) levels ≥292 IU/L (HR 6.804, 95% CI: 1.629-28.416, p=0.009), C-reactive protein (CRP) levels ≥21 mg/dL (HR 28.073, 95% CI: 5.654-139.462, p

الوصف: A 60-year-old man was referred to us with high levels of aspartate aminotransferase and lactate dehydrogenase (LDH). He did not complain of any symptoms; however, he had been diagnosed with lumbar disc herniation, even though his back pain improved only to half of its previous level with pregabalin. Thus, we asked about the red flag of back pain and confirmed that he had involuntary body weight loss, which led us to diagnose truly non-secretory multiple myeloma, a variant of multiple myeloma that is associated with M-protein negativity and a normal serum free light chain level.

الوصف: We herein report a 74-year-old woman who presented with autoimmune hemolytic anemia (AIHA) associated with pleural solitary fibrous tumor (SFT). Her AIHA was initially treated with 1 mg/kg daily of oral prednisolone (PSL) for 2 months, which had a limited effect. However, after surgical tumor resection, the patient showed remarkable improvement of AIHA with normalizations of serum lactate dehydrogenase and bilirubin levels, and we were able to rapidly reduce the PSL dosage. This is the first description of a case of AIHA caused by SFT.

الوصف: Objective To clarify the clinical significance of vascular endothelial growth factor (VEGF) in Japanese patients with small cell lung cancer (SCLC).Materials and Methods We measured serum VEGF levels using an enzyme-linked immunosorbent assay in 45 patients with SCLC before treatment and in 38 patients with benign pulmonary disease and in 32 healthy subjects (71 non-malignant subjects). VEGF immunostaining was performed in tissue biopsies obtained from 23 SCLC patients during bronchoscopic examination.Results Median serum VEGF level was 332 pg/ml in patients with SCLC and 160 pg/ml in non-malignant subjects, respectively. The 95% cut-off level to exclude non-malignant subjects was 500 pg/ml. An elevated VEGF level (>500 pg/ml) was found more frequently in patients with extensive disease of SCLC than in those with the limited disease (p

الوصف: OBJECTIVE To investigate the clinical characteristics, diagnostic approaches, short-term efficacy of treatment and prognosis of lymphoma patients presenting with a fever of unknown origin (FUO). METHODS We reviewed the records of 132 patients finally diagnosed with lymphoma in Huashan Hospital, half of whom initially presented with a FUO. The other 66 lymphoma patients without a history of FUO were diagnosed within a month when several patients in the FUO group were also diagnosed. RESULTS The patients presenting with a FUO were predominantly young men (71.21%, p=0.35) characterized by a temperature ≥ 39°C (55/66, 83.33%). Compared with the non-FUO group, patients in the FUO group more often had pancytopenia and hypohepatia, 61.54% with hypoalbuminemia (p

الوصف: A 46-year-old man presented with fever, thrombocytopenia, and a considerable accumulation of ascites. Although prednisolone and intravenous cyclophosphamide pulse (IVCY) were effective, he experienced recurrence. Renal insufficiency and hemolytic anemia developed subsequently. Schistocytes, negative Coombs' test, and elevated lactate dehydrogenase levels indicated thrombotic microangiopathy (TMA). He recovered well after receiving plasma infusion, IVCY, and prednisolone. Renal biopsy revealed subendothelial widening, thereby confirming TMA. This is a very rare case of TMA that presented with a considerable volume of ascites.

الوصف: Objective Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) occurs during the chronic progressive course of idiopathic pulmonary fibrosis. Mortality is estimated to be >70%, because no effective treatment has been established. We evaluated the effectiveness of combination therapy of tacrolimus and methylprednisolone for AE-IPF. Methods Patients of AE-IPF treated with methylprednisolone pulse therapy with or without tacrolimus (targeting 20 ng/mL) during the period between January 2001 and April 2010 were retrospectively reviewed. The primary endpoints were survival rate and duration. We also observed lactate dehydrogenase levels, partial pressure of arterial oxygen/fraction of inspired oxygen ratio (P/F ratio), KL-6, occurrence of re-exacerbation, and computed tomography score. Results Fifteen Japanese patients [tacrolimus group aged 74.2±6.0 years old (n=5), non-tacrolimus group aged 75.1±12.8 years old (n=10)] were identified. Pre-treatment clinical parameters were not significantly different between the two groups. Four of 5 tacrolimus group patients and 1 of 10 non-tacrolimus group patients survived (p 92 days (tacrolimus group) and 38 days (non-tacrolimus group) (p
