Compression therapy using surgical gloves is ineffective for the prevention of vincristine-induced neuropathy in patients with malignant lymphoma.

PURPOSE: Vincristine (VCR) often induces peripheral neuropathy (PN) as an adverse event. Currently, there is no consensus on the prevention of vincristine-induced PN (VIPN). In this study, we aimed to investigate the efficacy of compression therapy using surgical gloves for preventing VIPN. METHODS: Patients with malignant lymphoma (vincristine-naïve) who were receiving chemotherapy with cyclophosphamide, doxorubicin, VCR, and prednisolone, with or without rituximab, every 3 weeks for six cycles were eligible. For every VCR infusion, each patient wore two one-size-smaller gloves on one hand (study hand) for 90 min. The other hand was left bare (control hand). PN was assessed at each treatment using the Common Terminology Criteria for Adverse Events ver. 4.0. RESULTS: Fifty-one patients with malignant lymphoma were enrolled and 44 were evaluated. At 1 month after treatment, the occurrence rates of grade ≥ 2 sensory PN were 13.6 and 13.6% in the study and control hands, respectively (p = 1.0), and those of grade ≥ 2 motor PN were 15.9 and 15.9% in the study and control hands, respectively (p = 1.0). CONCLUSION: Compression therapy using surgical gloves showed no significant effect for the prevention of VIPN.

[TCL1-family negative T-cell prolymphocytic leukemia with rapid progression of extranodal disease despite a normal white blood cell count].

Here we describe the case of a 69-year-old man who was found to have moderate thrombocytopenia and severe splenomegaly during a medical checkup at the age of 67. At the first visit, his white blood cell (WBC) count was 7,400/µl with 80% lymphocytes, and bone marrow aspiration showed 24% atypical lymphocytes. Flow cytometry of atypical lymphocytes was positive for mature T-cell markers, and T-cell clonality was revealed by T-cell receptor gene rearrangement. TCL1 was negative on immunohistochemistry. We diagnosed TCL1-family negative T-cell prolymphocytic leukemia (T-PLL) and employed watchful waiting. Thirty months after diagnosis, the patient developed urinary retention and right lower-limb paresis despite a normal WBC count, and an extradural tumor around the thoracic vertebrae and spinal cord compression were detected. The tumor was diagnosed as extranodal involvement of TCL1-family negative T-PLL, but the patient's general condition deteriorated rapidly, and no treatment was possible. T-PLL is a rare disease characterized by leukocytosis, and the WBC count generally increases with disease progression. Although blood counts are recommended for observation, it is important to keep in mind that the disease may worsen even if blood counts do not change.

Alterations in Intratumoral Immune Response before and during Early-On Nivolumab Treatment for Unresectable Advanced or Recurrent Gastric Cancer.

We investigated the tumor immune response in gastric cancer patients receiving third-line nivolumab monotherapy to identify immune-related biomarkers for better patient selection. Nineteen patients (10 males, median age 67 years) who received nivolumab as a third- or later-line therapy were enrolled. We analyzed the tumor immune response in durable clinical benefit (DCB) and non-DCB patients. Pre-treatment and early-on-treatment tumor transcriptomes were examined, and gene expression profiles, immunograms, and T cell receptor (TCR) repertoire were analyzed. DCB was observed in 15.8% of patients, with comparable secondary endpoints (ORR; objective response rate, OS; overall survival, PFS; progression-free survival) to previous trials. The immunograms of individual subjects displayed no significant changes before or early in the treatment, except for the regulatory T cell (Treg) score. Moreover, there were no consistent alterations observed among cases experiencing DCB. The intratumoral immune response was suppressed by previous treatments in most third- or later-line nivolumab recipients. TCR repertoire analysis revealed newly emerged clonotypes in early-on-treatment tumors, but clonal replacement did not impact efficacy. High T cell/Treg ratios and a low UV-radiation-response gene signature were linked to DCB and treatment response. This study emphasizes the tumor immune response's importance in nivolumab efficacy for gastric cancer. High T cell/Treg ratios and specific gene expression signatures show promise as potential biomarkers for treatment response. The tumor-infiltrating immune response was compromised by prior treatments in third-line therapy, implying that, to enhance immunotherapeutic outcomes, commencing treatment at an earlier stage might be preferable. Larger cohort validation is crucial to optimize immune-checkpoint inhibitors in gastric cancer treatment.

[FIP1L1::PDGFRA-positive chronic eosinophilic leukemia showing slowly progressive cardiac impairment].

This report describes a 69-year-old man with eosinophilia that was detected during a medical check-up. A review of his medical history revealed that his absolute eosinophil count was 990/µl at the age of 55 and increased to 5,380/µl at the age of 69. Electrocardiogram revealed first-degree atrioventricular block at the age of 58, followed by ST-segment depression and a negative T wave at the age of 65. The echocardiogram was normal at the age of 65. We diagnosed him with FIP1L1::PDGFRA-positive chronic eosinophilic leukemia by detecting the FIP1L1::PDGFRA fusion gene by fluorescence in situ hybridization. He had no symptoms at the first visit; however, echocardiography and contrast-enhanced computed tomography revealed an abnormal structure, considered a thrombus, within the left ventricular apex and apex wall thickening. We initiated imatinib (100 mg/day), and the eosinophilia disappeared in a month. However, his cardiac impairment worsened, and he gradually developed symptoms of heart failure. This case is valuable because it shows the long-term course of the disease, with 15 years of laboratory findings until diagnosis. Our findings suggest that in cases of eosinophilia with an abnormal electrocardiogram, contrast-enhanced cardiac magnetic resonance imaging should be considered earlier.

[Myeloid sarcomas of the shoulder and testis relapsing 9 years after allogenic stem cell transplantation for acute myeloid leukemia].

This report describes a 56-year-old man who was diagnosed with myeloid sarcoma (MS) of the testis and right shoulder after receiving allogenic stem cell transplantation (allo-SCT) at the age of 47 for acute myeloid leukemia (AML) with inv (16) (p13.1;q22). Nine years after allo-SCT, he complained of a painful right testicular mass. He underwent orchiectomy, and the pathologic diagnosis was MS. Inv (16) was identified by fluorescence in situ hybridization (FISH) using testicular tumor specimens. 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET-CT) revealed FDG accumulation in the right shoulder. FISH analysis of bone marrow aspirate revealed no increase in blasts and ruled out CBFB-MYH11 fusion. Reinduction chemotherapy, consolidation, and local radiation therapy for the left testis and right shoulder were administered to him. After that, he received a second allo-SCT from an unrelated donor who was HLA-matched. As of 2 years after the second allo-SCT, recurrence of neither AML nor myeloid sarcoma has been observed. The recurrence of MSs without bone marrow involvement is frequently reported in single, multiple single organs, or multiple single regions. Even if MSs recur in a distant location, combining systemic and local treatment may be a better treatment strategy.

The effectiveness of bench press training with or without throws on strength and shot put distance of competitive university athletes.

PURPOSE: Maximum force exertion against various resistance levels (heavy-light) is commonly implemented to improve both strength- and speed-oriented components of power. Medium-light resistances allow rapid accelerations, yet incur significant decelerations in the later concentric phase to bring the bar to a halt, which may limit the concentric effort and, therefore, the effectiveness of training. Accordingly, ballistic actions have been recommended. This study evaluated the effectiveness of power bench press training, with the bar thrown on a Smith machine (BPthrow) or without throwing (BPnon-throw), for developing strength and shot put distance. METHODS: Nine university shot-putters performed BPthrow and BPnon-throw at 50, 40 and 30% 1RM, as well as seated and standing shot put trials. Peak angular velocities at the elbow were measured in these tasks using a wireless electro-goniometer. Participants underwent 24 sessions of training (12 weeks) with either BPthrow (n = 5) or BPnon-throw (n = 4) at the three intensities (20 s × 2 sets at 50, 40 and 30% 1RM). RESULTS: The peak elbow velocity during BPthrow was 1.7 times greater than BPnon-throw for all intensities. The velocity of BPthrow at 30% 1RM (854.7°/s), however, was still slower than seated (1121.3°/s) and standing (1539.1°/s) shot puts. BPthrow training significantly improved 1RM (+ 10.0%) and the distances of seated (+ 11.7%) and standing (+ 3.8%) shot puts, while no performance changes occurred after BPnon-throw training. CONCLUSION: When undergoing power bench press against medium-light resistances, maximum ballistic actions are important strategies for improving 1RM and shot put performance of university shot-putters.

Myelodysplastic syndrome with neutrophilic dermatosis successfully treated with azacitidine.

A 66-year-old male underwent prednisolone (PSL) therapy of 13 mg/day for rheumatoid arthritis (RA). Antiphospholipid antibody syndrome, neutrophilic dermatosis (ND), and myelodysplastic syndrome (MDS) developed. Treatment of MDS required red cell concentrate transfusion, and second courses of azacitidine therapy (75 mg/m2 daily, intravenous injection for 7 consecutive days) led to hematologic remission. Furthermore, ND improved early after the start of azacitidine therapy, making it possible to decrease the dose of PSL. After 12th courses of azacitidine therapy, treatment was discontinued and the long-term remission of MDS and ND has been maintained. During the course, the level of matrix metalloproteinase-3, as a marker of RA, also decreased. There are few case reports of MDS in which azacitidine was effective for autoimmune diseases, including ND. We report the present case.

[Acute painful crisis in a female Nigerian patient with sickle cell disease].

We report a 38-year-old Nigerian woman with sickle cell disease. Sickle cell disease had been diagnosed when she experienced her first sickle cell crisis episode at age 8 years. Thereafter, she had infrequent minor episodes. She visited a hospital presenting with fever, anemia, jaundice, and systemic pain, and was then transferred to our hospital. Together with rehydration and red blood cell transfusion, analgesics and antibiotics were prescribed, and produced gradual improvement of all symptoms and signs. The patient was discharged on day 9 of hospitalization. Sickle cell crisis is an acute painful episode caused by occlusion of arterioles. The degree of pain and accompanying symptoms, as well as the frequencies of crises, are variable. Moreover, one third of individuals with sickle cell disease never experience a crisis. As our society becomes increasingly globalized, the probabilities of encountering sickle cell disease patients will be higher.

In vitro Evaluation Method of UV Protecting Ability of Sunscreens: Clarifying and Overcoming Problems to Develop New Method.

Factors influencing on in vitro evaluation of UV protecting ability of sunscreens were analyzed. It was found that any factors making the sunscreen layer spatially inhomogeneous, such as directional viscous fingering during the sunscreen application, dewetting of applied sunscreen layer, and the surface roughness of the standard PMMA plate, alter the UV transmittance. New application procedure and new type of flat hydrophilic plate were developed for inhibiting the generation of spatial inhomogeneity in applied sunscreen layer. The method created by the combination of these newly developed technologies succeeded in providing reliable and reproducible in vitro evaluation of UV protecting ability.

Investigation on the Validity of in vitro Sun Protection Factor and Ultraviolet-A Protection Factor Evaluation Method for Sunscreen Samples.

Factors affecting the in vitro Sun Protection Factor (SPF) and Ultraviolet-A Protection Factor (UVA-PF) of sunscreens were analyzed for verifying the validity and reliability of the ISO24443 evaluation method. UV absorbance measurements by different spectrophotometers did not lead to the large difference in in vitro SPF/UVA-PF, although the UV absorbance determined by each spectrophotometer exhibited relatively large difference when it was larger than 2. On the other hand, relatively large difference was found in in vitro SPF/UVA-PF by utilizing European Cosmetic and Perfumery Association (Colipa) 1994 or UV-solar simulated radiation (UV-SSR) for the spectral irradiance. Appropriateness of employing the coefficient of adjustment for the determination of in vitro UVA-PF was also found to be reexamined.
