| 1 | Angiotensin receptor blocker neprilysin inhibitors显示文摘Heart failure(HF)is a clinical syndrome that results from a structural or functional cardiac disorder that reduces the ability of the ventricle of the heart to fill with,or eject,blood.It is a multifaceted clinical condition that affects up to 2%of the population in the developed world,and is linked to significant morbidity and mortality;it is therefore considered a major concern for public health.Regarding the mechanism of HF,three neurohumoral factors-the reninangiotensin-aldosterone system,the sympathetic nervous system,and natriuretic peptides—are related to the pathology of chronic HF(CHF),and the targets of treatment.Angiotensin receptor blocker and neprilysin inhibitor(angiotensinreceptor neprilysin inhibitor),namely sacubitril/valsartan(SAC/VAL),has been introduced as a treatment for CHF.SAC/VAL is an efficacious,safe,and costeffective therapy that improves quality of life and longevity in patients with HF with reduced ejection fraction(HFrEF),and reduces hospital admissions.An inhospital initiation strategy offers a potential new avenue to improve the clinical uptake of SAC/VAL.In the last five years,SAC/VAL has been established as a cornerstone component of comprehensive disease-modifying medical therapy in the management of chronic HFrEF.On the other hand,further work,with carefully designed and controlled preclinical studies,is necessary for understanding the molecular mechanisms,effects,and confirmation of issues such as long-term safety in both human and animal models. | Daisuke Usuda Toshihiro Higashikawa Yuta Hotchi Kenki Usami Shintaro Shimozawa Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Toshihiko Yoshizawa Suguru Asako Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2021 | World Journal of Cardiology2021，13，8： | 2 |
| 2 | Intracranial malignant solitary fibrous tumor metastasized to the chest wall:A case report and review of literature显示文摘BACKGROUND Solitary fibrous tumor(SFT)is a rare fibroblastic mesenchymal neoplasm that affects spindle cell soft tissues with broad-spectrum biological behavior;it is predominantly benign,and rarely metastasizes.SFT occurs mainly in the tissue structure of the serosa in the pleura and the thorax,and can be found throughout the body,though extra-thoracic localization,including the cephalic region,is uncommon.We reported the first case of intracranial malignant SFT metastasized to the chest wall.CASE SUMMARY An 81-year-old Japanese man was referred to our hospital due to progressive gait disturbance and appetite loss.His medical history included partial resection due to brain tumor,four times,and 50-Gray radiation therapy at another hospital,starting when he was 74 years old.An unenhanced head computed tomography(CT)scan revealed an 8 cm×5.1 cm×6.5 cm mixed-density mass at the left frontal lobe,accompanying a midline shift,and an unenhanced chest-abdomen CT scan revealed a 6 cm×4.1 cm×6.5 cm low-density mass in the left chest wall.A CT-guided percutaneous lung biopsy was performed,and the pathological findings were SFT corresponding to brain tumor.Finally,the correct diagnosis of his brain tumor in history of past illness revealed to be SFT,and the unremovable tumor,namely present brain lesions enlarged and metastasized to the chest wall.We established a definitive diagnosis of intracranial malignant SFT metastasized to the chest wall.We notified him and his family of the disease,and offered palliative care.He passed away on the 29 th hospital day.CONCLUSION This case suggests the need for careful,detailed examination,and careful followup when encountering patients presenting with a mass. | Daisuke Usuda Shinya Yamada Toshihide Izumida Ryusho Sangen Toshihiro Higashikawa Ken Nakagawa Masaharu Iguchi Yuji Kasamaki | 2020 | World Journal of Clinical Cases2020，8，20： | 2 |
| 3 | Exophiala dermatitidis显示文摘Exophiala is a genus comprising several species of opportunistic black yeasts,which belongs to Ascomycotina.It is a rare cause of fungal infections.However,infections are often chronic and recalcitrant,and while the number of cases is steadily increasing in both immunocompromised and immunocompetent people,detailed knowledge remains scarce regarding infection mechanisms,virulence factors,specific predisposing factors,risk factors,and host response.The most common manifestations of Exophiala infection are skin infections,and the most frequent type of deep infection is pulmonary infection due to inhalation.The invasive disease ranges from cutaneous or subcutaneous infection to systemic dissemination to internal organs.The final identification of the causative organism should be achieved through a combination of several methods,including the newly introduced diagnostic analysis,matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry,together with sequencing of the ribosomal ribonucleic acid internal transcribed spacer region of the fungi,and histological and culture findings.Regarding treatment,because anti-infective agents and natural compounds exhibited poor antibiofilm activity,few treatments have ultimately been found to be effective for specific antifungal therapy,so the optimal antifungal therapy and duration of therapy for these infections remain unknown.Therefore,most forms of disease caused by Exophiala dermatitidis require aggressive combination therapies:Both surgical intervention and aggressive antifungal therapy with novel compounds and azoles are necessary for effective treatment. | Daisuke Usuda Toshihiro Higashikawa Yuta Hotchi Kenki Usami Shintaro Shimozawa Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Toshihiko Yoshizawa Suguru Asako Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2021 | World Journal of Clinical Cases2021，9，27： | 0 |
| 4 | Diffuse large B cell lymphoma originating from the maxillary sinus with skin metastases:A case report and review of literature显示文摘BACKGROUND Diffuse large B-cell lymphoma(DLBCL)is the most common type of malignant lymphoma(ML),accounting for 30%-40%of cases of non-Hodgkin’s lymphoma(NHL)in adults.Primary paranasal sinus lymphoma is a rare presentation of extranodal NHL that accounts for only 0.17%of all lymphomas.ML from the maxillary sinus(MS)is a particularly rare presentation,and is thus often difficult to diagnose.We have reported the first known case of DLBCL originating from the MS with rapidly occurrent multiple skin metastasis.CASE SUMMARY An 81-year-old Japanese man visited our hospital due to continuous pain for 12 d in the left maxillary nerve area.His medical history included splenectomy due to a traffic injury,an old right cerebral infarction from when he was 74-years-old,hypertension,and type 2 diabetes mellitus.A plain head computed tomography(CT)scan revealed a 3 cm×3.1 cm×3 cm sized left MS.On day 25,left diplopia and ptosis occurred,and a follow-up CT on day 31 revealed the growth of the left MS mass.Based on an MS biopsy on day 50,we established a definitive diagnosis of DLBCL,non-germinal center B-cell-like originating from the left MS.The patient was admitted on day 62 due to rapid deterioration of his condition,and a plain CT scan revealed the further growth of the left MS mass,as well as multiple systemic metastasis,including of the skin.A skin biopsy on day 70 was found to be the same as that of the left MS mass.We notified the patient and his family of the disease,and they opted for palliative care,considering on his condition and age.The patient died on day 80.CONCLUSION This case suggests the need for careful,detailed examination,and for careful follow-up,when encountering patients presenting with a mass. | Daisuke Usuda Toshihide Izumida Nao Terada Ryusho Sangen Toshihiro Higashikawa Sayumi Sekiguchi Risa Tanaka Makoto Suzuki Yuta Hotchi Shintaro Shimozawa Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Suguru Asako Yoshie Takagi Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita Yuji Kasamaki | 2021 | World Journal of Clinical Cases2021，9，23： | 0 |
