Since respiratory sample collection is an uncomfortable experience, simultaneous detection of pathogens with a single swab preferable. We prospectively evaluated the clinical performance newly developed antigen test QuickNavi-Flu+COVID19 Ag (Denka Co., Ltd., Tokyo, Japan) which can detect severe acute syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses at same time testing device.We included those who were suspected contracting disease 2019 (COVID-19) referred to PCR center Ibaraki...

Deficiency of multiple vitamins can be identified in alcoholic and malnourished patients. We report a patient with Wernicke encephalopathy, B1 deficiency pellagra, niacin deficiency. A 61-year-old Japanese man presented generalised weakness. He had drunk alcohol heavily for more than year without eating adequate meals. Physical examination showed disorientation, eye movement impairment, muscle wasting rash over the limbs. Multivitamin supplementations improved all symptoms. Pellagra causes...
Abstract Introduction Since respiratory sample collection is an uncomfortable experience, simultaneous detection of pathogens with a single swab preferable. We prospectively evaluated the clinical performance newly developed antigen test QuickNavi-Flu+COVID19 Ag (Denka Co., Ltd., Tokyo, Japan) which can detect severe acute syndrome coronavirus 2 (SARS-CoV-2) and influenza viruses at same time testing device. Methods Included were those who suspected contracting disease 2019 (COVID-19)...
IntroductionRapid qualitative antigen testing is essential in the clinical management of COVID-19. However, most evaluations tests have been performed before emergence Omicron variant.MethodsThis prospective observational study evaluated QuickNavi-COVID19 Ag, a rapid detection test between December 2021 and February 2022 Japan, using real-time reverse transcription (RT)-PCR as reference. Two nasopharyngeal samples were simultaneously collected for RT-PCR. Variant analysis SARS-CoV-2 genomic...
An 81-year-old man with lung cancer bone metastases, interstitial pneumonia, and emphysema, was hospitalized for pain control. He developed fever chills during hospitalization. Physical examination revealed a of 39.1 °C, but there were no findings on history or physical to suggest the source infection. Gram-negative cocci detected in blood culture (Fig. 1) Gram stained sputum smear (Figs. 3 4). Neisseria meningitis gonorrhoeae ruled out based an absence suggestive symptoms. The cause his...
A case of a Borrmann type 2 advanced gastric cancer with endocrine differentiation is described. Histologically, the was either composed cells arranged in tubular pattern or formed solid nests various sizes. The moderately differentiated adenocarcinoma. histology showed partial carcinoid tumor‐like features. Cancer inside had signet‐ring cell‐like appearance. Periodic‐acid Schiff (PAS) staining positive cytoplasm few found and mucus some lumens on apical surface lumens, but PAS did not stain...
Isolated adrenocorticotropic hormone deficiency (IAD) is a rare disorder with diverse clinical presentations. A 79-year-old man was bedridden for six months due to flexion contractures of the bilateral hips and knees, along hyponatremia. He diagnosed IAD based on results endocrine tests. After one month corticosteroid replacement, he recovered able stand up by himself. Although contracture symptom IAD, steroid replacement therapy may be effective, even seemingly irreversibly elderly...
The clinical significance of enterococci in intra-abdominal infections, particularly those caused by multiple organisms, remains unclear. There are no definitive guidelines regarding the use empiric therapy with antimicrobial agents targeting enterococci. In this study, we evaluated impact initial administration anti-enterococcal on treatment infections patients cancer whom were isolated from ascitic fluid cultures. This retrospective study was conducted at Shizuoka Cancer Center between...
Although recent propagation of carbapenemase-producing Enterobacterales (CPE) has become a problem worldwide, the picture CPE infection in Japan not fully been elucidated. In this study, we examined clinical and microbiological characteristics invasive occurring at 8 hospitals Minami Ibaraki Area between July 2001 to June 2017. Of 7294 strains isolated from independent cases bacteremia and/or meningitis, 10 (0.14%) were (8 Enterobacter cloacae-complex, 1 Escherichia coli, Edwardsiella...
症例は52歳の女性. 主訴は食後の腹満感, 嘔吐と体重減少. 近医の上部消化管造影X線検査で横隔膜ヘルニアと診断され, 当院を紹介され来院した. 当院の検査では, 食道裂孔ヘルニアで胃前庭部と十二指腸球部がヘルニア内に脱出嵌頓して通過障害を来していることが診断された. 内視鏡的整復が困難と判断され開腹手術を行い, 嵌頓した胃前庭部と十二指腸球部を還納後, ヘルニア門を縫合閉鎖して手術を終了した. 術後の上部消化管造影X線検査では正常な解剖学的位置関係に復しており, 通過も良好であった. 食道裂孔ヘルニアの定義では, 胃の漿膜を含む全層が胸縦隔内へ脱出する状態をいい, 胃以外の腹腔内臓器が脱出することは極めてまれとされている. 文献検索では, 十二指腸球部を内容とした食道裂孔ヘルニアの報告は4例のみで自験例は5 例目であり, 極めてまれであると考えられたので報告した.
症例は41歳，女性．５年前より右鼠径部に腫瘤を自覚，平成18年に入り腫瘤が圧痛を伴い周期的に大きくなるといった症状が加わったため当院外来を受診となった．触診にて右鼠径部に３cm大・弾性硬な腫瘤を触知，超音波・骨盤部CTよりNuck管水腫，粘液腫等を疑いインフォームドコンセントの上，診断・治療目的に手術を施行した．腫瘤は子宮円索末梢側に存在したため，子宮円索を含めて腫瘤を切除した．病理組織検査にて組織内に子宮内膜類似組織が混在しており，子宮内膜症と診断された．本症は外性子宮内膜症のうち約0.8％と比較的稀な疾患であり診断に難渋することが多いが，充分な病歴の聴取により症状と月経周期との関係を把握することが診断のポイントであると考えられる．鼠径部の腫瘤を主訴に来院した症例の診察にあたっては本症を鑑別診断の一つにあげ慎重な病歴の聴取を行う必要があると思われた．
直腸肛門部に発生し周辺粘膜に浸潤をきたした悪性黒色腫(以下,本症)の手術例を経験したので報告する.症例は,67歳の男性,主訴は血便.精査にて肛門縁から1.5cmの直腸肛門部に,腫瘤の一部と周辺粘膜に黒色を呈するIsp型ポリープを認め,本症を疑い同部より生検を行った.生検で本症と確定診断し,腹会陰式直腸切断術を行った.切除標本のポリープ部は深達度sm3,周辺粘膜部は深達度mであり,リンパ節転移は認めなかった.術後3カ月を経た現在,再発の兆候を認めず,経過観察中である.本症は稀な疾患で,早期にリンパ行性,血行性に転移をきたすため予後が極めて不良である.予後の改善には,早期診断と適切な外科的治療の確立が必要である.
