We investigated the frequency of various arthroscopic treatments and the short-term clinical outcomes of symptomatic isolated medial meniscus (MM) injuries. This retrospective observational study included 193 patients (197 knees) who underwent arthroscopic meniscal treatment for isolated MM injuries between January 2016 and April 2019. Arthroscopic meniscal repairs were divided into two groups: transtibial pullout repairs of MM posterior root tears (MMPRTs) and arthroscopic meniscal repairs for other types of MM injuries. MMPRT pullout repair, other meniscal repairs, and partial meniscectomy were performed in 71.0%, 16.8%, and 12.2% of the knees, respectively. The ratio of women to men and the patient age were higher in the pullout-repair group than the meniscal-repair group. The Preoperative Knee Injury and Osteoarthritis Outcome Score subscale (as an index of daily living activities) was significantly lower in the pullout-repair group than the meniscus-repair group. However, no significant differences were observed in these scores among the two groups postoperatively. Our results suggest that familiarity with the diagnosis and treatment of MMPRTs is necessary for orthopedic surgeons to manage isolated MM injuries.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"78 1","pages":"21-27"},"PeriodicalIF":0.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139989049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, our prognostic data at the time lacked a sufficient observation period. Herein, we analyze the longer-term follow-up data, focusing on the status of eventual CVP implantation via an open-label, non-randomized, multicenter study. This study enrolled 55 patients (mean age, 64 years), of whom 43 died (41 of primary cancer). The median overall survival was 22.7 months (95% CI: 20.1-34.7 months). Post-treatment regimens after failure of first-line treatment were initiated in 43 patients; CPT11-based regimens were selected in most cases, and other oral FU combinations in nine. CVP was implanted in 35 patients prior to first-line treatment; eleven of the remaining 20 patients did not require CVP implantation. In conclusion, we report here the final prognostic update of the Phase II clinical trial examining the efficacy of SOX plus bevacizumab therapy, the results of which confirm the clinical efficacy of this regimen.","PeriodicalId":7017,"journal":{"name":"Acta medica Okayama","volume":"78 1","pages":"47-52"},"PeriodicalIF":0.5,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139989053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biopsies were indicated for a rising prostate-specific antigen (PSA) level, positive digital rectal examination findings, or the appearance of de novo low apparent diffusion coefficient lesions on MRI. The control group was comprised of 28 age- and PSA-matched patients. The relationships among the cancer detection rate and the patients' PSA levels and MRI findings were analyzed.

The three patients in the BCG group in whom prostate cancer was detected had all undergone the biopsy > 1 year after their BCG treatment.

All patients had been evaluated for the presence of necrosis within lesions via CT scan upon first suspicion of MTX-LPD (baseline CT scan). The percentage lesion size reduction between the baseline and initial follow-up CT scan was calculated. The association between necrosis within lesions and size changes was estimated via linear regression analyses using both crude and adjusted models. Necrosis was significantly more common in extranodal lesions (27 out of 30 lesions, 90%) than in nodal lesions (9 out of 59 lesions, 15%, p<0.001). In the crude model, the regression of necrotic lesions was 58.5% greater than that of non-necrotic lesions; the difference was statistically significant (p<0.001). Additionally, the longest diameter of necrotic lesions at the baseline CT scan was significantly greater than that of non-necrotic lesions (p<0.001). Based on the adjusted model, necrotic lesions showed 49.3% greater regression than non-necrotic lesions (p=0.017).

This study quantifies heat energy transfer capacity of ice bags and evaluates their cooling effects on body temperature. Forty-eight healthy adults in their 20s were recruited. An ice bag wrapped in two layers of dry towel was applied to the forehead, neck, or palm of each participant for 10 min. The skin surface temperature, heat flow, and core temperature were recorded during the cooling and non-cooling periods, with energy transfer calculated by integrating heat flow over time. Over the non-cooling period, 31.4-53.6 kJ·m-2 of energy was dissipated over 10 min, whereas during the cooling period, the range increased to 180.0-218.7 kJ·m-2 over 10 min. Skin surface temperature decreased by 3.2-5.7°C, whereas core temperature was unchanged. Ice bag use augmented energy transfer by about 150-180 kJ·m-2 over 10 min, but this was insufficient for rapid whole body cooling due to the small skin-surface area in contact with the ice bag. The measured energy transfer indicated that topical ice bag application absorbs insufficient energy to affect core temperature.
