Portal vein thrombosis (PVT) while using an angiogenesis inhibitor is relatively rare. A 70-year-old Asian man was diagnosed with PVT two months after initiating 5-fluorouracil/leucovorin, irinotecan, and bevacizumab therapy for rectal cancer with liver metastases. Because the metastases were small and shrinking, we suspected that the thrombosis might have been caused by bevacizumab-containing chemotherapy. We stopped bevacizumab and started apixaban, a direct oral anticoagulant (DOAC). Eight months later, the complete dissolution of the thrombus and recanalization of the portal vein were attained. Our case suggests that PVT can occur during bevacizumab-containing chemotherapy, and DOAC therapy might be beneficial for treating PVT in patients with cancer.

症例1は6歳女児.インフルエンザ感染症初日に発熱しオセルタミビルを開始.第3病日,右下腹部に限局した圧痛が出現.腹部造影CTで糞石を認め急性虫垂炎と診断.保存的に加療し炎症反応と腹痛は改善した.症例2は5歳女児.第1病日に発熱と腹痛を認め,第3病日に鼻咽腔迅速検査でインフルエンザB型と診断しザナミビル吸入を開始.触診で右下腹部に反跳痛を認め,腹部単純CTで虫垂壁の肥厚と糞石を確認.急性虫垂炎の併発と診断し,第4病日に虫垂切除術を施行.切除虫垂に膿瘍を認め腹腔ドレーンを留置.第5病日に解熱し経過は順調であった.インフルエンザに伴う腹痛では感染に付随する腹痛と断定せず急性虫垂炎の可能性も考慮し腹部CTなどの画像検査を行うことが肝要である.

Sportswear is widely used in various sports and serves multiple functions. A key feature is the ability to absorb sweat during physical activity, which can, however, cause discomfort due to stickiness. This study focuses specifically on the stickiness caused by sweat between sportswear and the skin by objectively evaluating stickiness using specific physical parameters and correlating them with sensory evaluation values. Moreover, there is little research on the adhesion force between sportswear and human skin. Therefore, this study aims to achieve the following objectives: (1) investigate the relationship between the adhesion force between human skin and fabrics and the sensation of stickiness; (2) examine the relationship between the adhesion force between artificial skin and fabric and that between human skin and fabric; and (3) clarify the impact of fabric wettability and geometry on the adhesion force under wet conditions. Experiments reveal that the sensory evaluation value and adhesion force against human skin corresponded. Additionally, a positive correlation was found between the adhesion force against human skin and an artificial skin sheet. These experimental results suggest that fabrics with a lower adhesion force can be achieved by decreasing the load area ratio at 30% Φ0.3 and increasing the contact angle and meniscus height.

Aortitis is a rare adverse event associated with granulocyte colony-stimulating factor (G-CSF). Contrast-enhanced computed tomography (CECT) is widely used to diagnose G-CSF-associated aortitis. However, the usefulness of gallium scintigraphy for the diagnosis of G-CSF-associated aortitis is unknown. We herein report a set of pre- and post-treatment gallium scintigrams of a patient with G-CSF-associated aortitis. During the diagnosis, gallium scintigraphy revealed hot spots on the arterial walls that appeared inflamed on CECT. Both the CECT and gallium scintigraphy findings disappeared. Gallium scintigraphy can be a supportive diagnostic tool for G-CSF-associated aortitis, especially in patients with an impaired renal function or allergy to iodine contrast.

An atmospheric-pressure argon (Ar) plasma jet was generated with a frequency of 10 kHz, an applied voltage of 10 kV, and an Ar gas flow rate of 10 L/min. When an aluminum (Al) thin film deposited on a glass substrate was irradiated with the Ar plasma jet in air for 5 s, Al was removed. The removal rate was ∼700 nm/s. Because the streamers in the plasma reached the Al thin film, Al was removed and a mark was formed on the film, which was referred to as a removal mark. The shape of the removal mark depended on the irradiation distance: it was ring-shaped with an inner diameter of ∼5 mm and an outer diameter of ∼6 mm for irradiation distances of 2–7 mm, and disc-shaped with a diameter of ∼5 mm for irradiation distances of 10–20 mm. The dependence of the shape of the removal mark on the irradiation distance suggests that the distribution of the streamers in the plasma depended on the irradiation distance. The streamers inside the quartz tube were concentrated along the inner wall. In contrast, the streamers outside the tube were distributed in a ring shape with an inner diameter of ∼5 mm and an outer diameter of ∼6 mm for irradiation distances of 2–7 mm, but they converged then diverged to form a smaller disc shape with a diameter of ∼5 mm for irradiation distances of 10–20 mm.
