Aortitis is an inflammatory arteriopathy that often progresses to obliteration of multiple large arteries. Surgical treatment for obstructive lesions due to aortitis syndrome therefore is difficult in many cases. The patient was a 23-year-old female who at the age of 19 had been diagnosed as aortitis syndrome with cerebral vessel involvement, and she subsequently received steroids. She increasingly experienced syncopal attacks, and was indicated for surgical treatment. Angiography revealed obstruction of the left common carotid and left subclavian arteries, and severe stenosis of the right common carotid and right vertebral arteries. She underwent bilateral ascending aorta-carotid artery bypass operation with 7mm ring-supported EPTFE grafts. After the operation she developed clinical signs of temporary brain damage due to hyperperfusion syndrome, but she now completely recovered and maintains a good clinical condition.

Mortarity due to pesticide poisoning for prefectures in Japan is examined according to the vital statistics in 1979-1981. The atlases of pesticide poisoning mortality for prefectures in Japan are presented.
There is a wide range in mortality among prefectures and the highest mortality is 17.8 times as high as that observed in the prefecture which showed the lowest mortality. Regional characteristic is observed in the mortality. Northern part of Kanto Area and the southern part of Kyusyu Island show high mortality and low mortality is observed in Hokuriku Area.
The ratio of the deaths due to pesticide poisoning to those due to automobile accident also show wide range among prefectures. The highest ratio is 38.3% and the lowest is 2.4%. The ratio shows similar regional characteristic to that observed in mortality.

Objective: The study compared the treatment outcomes of surgery versus radiotherapy, including concurrent chemoradiotherapy, in stage Ib2–IIb cervical adenocarcinoma patients in Japan. Methods: Of 57,470 patients diagnosed with stage I–IV cervical cancer from January 2001–December 2011, 1,932 patients with stage Ib2–IIb cervical adenocarcinoma were initially treated by surgery or radiotherapy. The primary endpoint was 5-year overall survival (OS) in all and 614 propensity score-matched (PSM) patients (307 per group). We compared OS and prognosis factors based on age, primary stage, and treatment arm. Results: In Japan, >80% (n=1,573) of stage Ib2–IIb cervical adenocarcinoma patients underwent surgery. The 5-year OS of surgery vs. radiotherapy groups were 82.1% (n=704) vs. 79.7% (n=59) (hazard ratio [HR]=1.494; 95% confidence interval [CI]=0.826–2.702; p=0.181) for stage Ib2, 76.6% (n=239) vs. 66.7% (n=54) (HR=1.679; 95% CI=0.986–2.858; p=0.053) for stage IIa, and 71.1% (n=630) vs. 58.9% (n=246) (HR=1.711; 95% CI=1.341–2.184; p<0.001) for stage IIb. In 614 PSM patients balanced for age and carcinoma stage Ib2–IIb, the 5-year OS of surgery vs. radiation groups was 73.0% (n=307) vs. 65.5% (n=307) (HR=1.394; 95% CI=1.044–1.860; p=0.023). In multivariable analysis, age (HR=1.293; 95% CI=1.045–1.601; p=0.018), treatment arm, radiotherapy (HR=1.556; 95% CI=1.253–1.933; p<0.001), and stage IIb (HR=1.783; 95% CI=1.443–2.203; p=0.018) were independent prognosis factors for 5-year OS in stage Ib2–IIb adenocarcinoma patients. Conclusion Age (>65 years), treatment arm (radiotherapy), and stage IIb significantly affect OS in cervical adenocarcinoma patients. Surgery may be considered for <65-year-old patients with stage IIb adenocarcinoma.

Objective: To assess the efficacy of the FIGO 2018 classification system for nodal-specific classifications for early-stage cervical cancer; specifically, to examine the impact of nodal metastasis on survival and the effect of postoperative treatments, according to histological subtypes. Methods: This society-based retrospective observational study in Japan examined 16,539 women with the 2009 FIGO stage IB1 cervical cancer who underwent primary surgical treatment from 2004 to 2015. Associations of cause-specific survival (CSS) with nodal metastasis and postoperative adjuvant therapy were examined according to histology type (squamous cell carcinoma [SCC], n=10,315; and non-SCC, n=6,224). Results: The nodal metastasis rate for SCC was higher than that for non-SCC (10.7% vs. 8.3%, p<0.001). In multivariable analysis, the impact of nodal metastasis on CSS was greater for non-SCC tumors (adjusted-hazard ratio [HR], 3.11; 95% confidence interval [CI], 2.40–4.02) than for SCC tumors (adjusted-HR, 2.20; 95% CI, 1.70–2.84; p<0.001). Propensity score matching analysis showed significantly lower CSS rates for women with pelvic nodal metastasis from non-SCC tumors than from SCC tumors (5-year CSS rate, 75.4% vs. 90.3%, p<0.001). The CSS rates for women with nodal metastasis in SCC histology were similar between the postoperative concurrent chemoradiotherapy/radiotherapy and chemotherapy groups (89.2% vs. 86.1%, p=0.42), whereas those in non-SCC histology who received postoperative chemotherapy improved the CSS (74.1% vs. 67.7%, p=0.043). Conclusion The node-specific staging system in the 2018 FIGO cervical cancer classification is applicable to both non-SCC tumors and SCC tumors; however, the prognostic significance of nodal metastases and efficacy of postoperative therapies vary according to histology.

Cholesteatoma is a cystic non tumorous lesion of the temporal bone that has the ability to destroy nearby structures by its power to cause bone resorption and as a result, fatal complications prevail. We aimed to conduct a comprehensive review for pathogenesis of acquired cholesteatoma, bone resorption mechanisms, and offer a future vision of this serious disease. We have reviewed different theories for pathogenesis of acquired cholesteatoma including the most relevant and updated ones with special emphasis on the mechanisms of bone resorption through Medline/PubMed research using the keywords ‘aetiopathogenesis, bone resorption, acquired cholesteatoma, temporal bone, and cytokines.’ In order to strengthen our study, we searched the reference lists of identified reviews. Cholesteatoma is a subject of debate among otolaryngologists since it was prescribed firstly. Over many decades, several theories were postulated for aetiopathogenesis of cholesteatoma with a tendency to follow more than one theory to explain the proper nature of that disease. Until now, the mechanism of bone resorption has yet to be more clarified. In the last century, a leap has occurred in the field of biomolecular cholesteatoma research which improved our knowledge about its pathophysiology and bone destructive mechanism. However, surgery is still the only available treatment. We conclude that discovery of new therapeutic choices for cholesteatoma other than surgery by the use of anti-growth, anti-proliferative, apoptotic agents as well as medications that antagonize osteoclastogenesis should be the main concern in the future clinical and experimental research work. Also, searching for predictors of the aggressiveness of cholesteatoma can affect the timing of intervention and prevent occurrence of complications.

Objective: To evaluate the efficacy and safety of niraparib in Japanese women with heavily pretreated ovarian cancer. Methods: This Phase 2 open-label, single-arm study enrolled Japanese women with homologous recombination deficiency-positive relapsed, high-grade serous ovarian, fallopian tube, or primary peritoneal cancer who had completed 3–4 lines of therapy. The starting dose of niraparib was 300 mg administered once daily in continuous 28-day cycles until objective progressive disease, unacceptable toxicity, consent withdrawal or discontinuation. The primary endpoint, objective response rate (ORR), was assessed by the investigator using RECIST version 1.1. Safety evaluations included the incidence of treatment-emergent adverse events (TEAEs), including serious TEAEs. Results: Twenty women were enrolled and the confirmed ORR in the full analysis set (FAS) was 35.0% (7/20), consisting of 1 complete response and 6 partial responses. Disease control rate in the FAS was 90.0%. The most frequently reported TEAEs (>50%) were anemia, nausea, and platelet count decreased. One patient (5.0%) had TEAEs leading to discontinuation of niraparib whereas reductions or interruptions were reported in 14 (70.0%) and 15 (75.0%) patients, respectively. The median dose intensity (202.9 mg daily) corresponded to a relative dose intensity of 67.6%. Conclusion Efficacy and safety of niraparib in heavily pretreated Japanese women was comparable to that seen in an equivalent population of non-Japanese women. No new safety signals were identified.

Objectives: It is important for patients to make correct use of drug information (DI) to promote the proper use of medicines. Many patients use the Internet to find DI, but awareness about the websites of public institutions that provide DI is low. This study aimed to identify the actual use of the Internet for DI and associated problems to inform development of a comprehensive DI website for patients.Method: Patients with diabetes were set as a model case for patients who take medicines and need DI. A questionnaire survey was conducted among patients with diabetes who visited community pharmacies in Kagoshima City from March 2019 to October 2019. The survey covered Internet use, DI needs, methods of sourcing DI, and problems obtaining DI via the Internet.Results: There were 349 valid respondents (median age 64 years), of which 52.1% used the Internet at least once a week. Around half of the Internet users searched for DI on the Internet. More than half of these respondents chose a DI acquisition site because it “appeared at the top of search results” and was “easy to understand.” However, around half of these respondents felt that “there is too much information on the internet and I don’t know what is correct.”Conclusion: This study suggests that older patients with a long history of diabetes use the Internet to obtain DI. However, patients face various problems accessing DI via the Internet. It may be necessary to construct a comprehensive website that is easy to use and enhance public health literacy to support the proper use of medicines by patients.
