2020年度の老年看護学実習Ⅱは、新型コロナウイルス感染症の蔓延のため、臨地で実習をすることはできなかった。そのため、コロナ禍でも学生が臨地をイメージできるように、実習目的・目標は大幅に変更せずに工夫を行った。工夫した点は大きく三つである。一つ目は実習施設と遠隔ツールを用いた実習をしたことである。事前に教員が施設の受け持ち高齢者の情報を得て、学生に提示し、紙面上の情報のみでなく高齢者と直接コミュニケーションをとり情報を得る機会を設け、ケアプランの一部を実施した。二つ目は遠隔ツールを通して実習指導者の参加と助言を得る機会を設定したことである。全ての施設ではないが、施設オリエンテーション、学生が立案したケアプラン、レクリエーション、最終カンファレンスと４日間接続して助言を受けた。三つ目は高齢者への援助方法を紹介した動画を作成したことである。高齢者への援助は、体調に応じながら本人の持っている力を活かすことや尊厳に配慮することを基本とする。そのため、臨地の実際の場面をイメージできるような援助動画を作成し学生に提供した。今後は高齢者への看護技術を体験できる演習も組み合わせる必要があると考えている。

Background When diagnosing patients with bilateral breast cancer, it is challenging to determine the relationship between multiple breast cancer lesions at the individual patient level with certainty. Case presentation A 35-year-old Japanese woman was diagnosed with a left breast cancer. She was previously diagnosed with right pT3N3M0 stage IIIC breast cancer and underwent chemotherapy with targeted therapy, radiotherapy, and endocrine therapy as adjuvant treatment after mastectomy and axillary lymph node dissection. Approximately 2 years after the first surgery, her left breast cancer was preoperatively diagnosed as a contralateral primary breast cancer, and left mastectomy and axillary lymph node dissection were performed. Histopathologically, the tumor was determined to be invasive ductal carcinoma accompanied with several intraductal components. After a second surgery, mutation analysis of her bilateral breast cancer was performed in a clinical study, which revealed that her metachronous bilateral breast tumors had the same GATA3 and CSMD1 mutations. Thus, mutation analysis strongly supported her latter left breast cancer being a metastatic lesion from the former right breast cancer. Some difficulties in diagnosing bilateral breast cancer exist when determining whether they are double primary cancers or represent contralateral breast metastasis. The existence of intraductal components is a critical piece of information for suspecting primary lesions. However, this case demonstrated that metastatic contralateral breast lesions can have intraductal components. Conclusion Herein we report a genetically proven contralateral breast metastasis with some intraductal components.

In 2011, we developed bidirectional approach video-assisted neck surgery (BAVANS) for endoscopic thyroid cancer surgery. BAVANS combines two different approach pathways at 180 degrees to the cervical lesion for endoscopic thyroidectomy and complete cervical lymphadenectomy. We reported previously that the cranio-caudal approach is extremely useful for endoscopic complete lymph node dissection around the trachea. In 2014, we upgraded the initial BAVANS for better maneuverability and quality of lymph node dissection. A new high-tech rigid endoscope with a variable viewing direction (EndoCAMeleon™), has enabled us to reduce the camera port in the anterior neck while keeping the easy maneuverability and the same quality of central lymph node dissection (LND) as with the initial BAVANS. Endoscopic thyroid cancer surgery is now evolving concurrently with new visual technology.

Background: Human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus that causes adult T-cell leukemia/lymphoma (ATL), an aggressive form of T-cell malignancy. The relationship between HTLV-1 infection and cancer progression is controversial. HTLV-1 encodes oncogenic protein TAX1 and it is hypothesized that HTLV-1 infection is associated with breast cancer progression. In this study, we evaluated the relationship between HTLV-1 infection and clinicopathological factors in breast cancer patients. Methods: We retrospectively analyzed 610 patients with primary breast cancer who underwent surgical treatment without preoperative chemotherapy at Kagoshima University Hospital between January 2001 and January 2015. Results: When patients with and without HTLV-1 infection were compared, no differences in clinicopathological factors were observed, except for age. Disease-free survival and overall survival rates did not differ between groups. Conclusions: HTLV-1–positive patients were significantly older than HTLV-1–negative patients. It was supposed to be due to the fact that the HTLV-1 infection rate is decreasing. Any effect of HTLV-1 infection on breast cancer progression appears to be negligibly small.

Background Although a few cases of accessory breast cancer (ABC) have been reported, most were in the axillary region. We encountered an extremely rare case of ABC in the inframammary region (IMR). Case presentation The patient was a 68-year-old postmenopausal woman who had noticed a congenital accessory nipple in her left IMR with slight, occasional discharge 20 years ago. Recently, she noticed a mass under the accessory nipple and visited a nearby clinic; fine-needle aspiration cytology of the mass revealed that it was malignant. She presented to our department 2 weeks after she had noticed the mass. Physical and imaging examinations showed an irregular tumor mass 1.7 × 1.4 × 1.0 cm in size connected to the accessory nipple beneath the left normal breast. Neither distant metastasis nor lymph node swelling was observed. Ultrasound-guided core needle biopsy revealed the mass to be invasive ductal carcinoma. We diagnosed her tumor as ABC in the left IMR; cT1cN0M0: stage IA. Curative wide resection with sentinel node biopsy was performed. Intraoperative evaluation of the frozen section revealed a hot and green ipsilateral axillary lymph node that was free from carcinoma; therefore, nodal dissection was avoided. Histopathological examination including immunochemical staining revealed that the tumor was invasive ductal carcinoma arising from the accessory breast tissue, scirrhous type, 1.7 × 1.4 × 1.0 cm in size, with a solid intraductal component. There was no lymphovascular infiltration, and the surgical margin was 1.5 cm or more. The tumor was estrogen and progesterone receptor-positive, Her2/neu-negative, and had a Ki-67 labeling index of 20%. There was no involvement of the three hot and/or green nodes. The final classification was pT1cN0(sn)M0: stage IA. Letrozole 2.5 mg/day will be administered for 5 years as adjuvant hormonal therapy. Conclusions A cutaneous and/or subcutaneous lesion except for proper breast tissue on the milk line, or mammary ridge from axilla to groin may be an accessory breast tissue. Its serial abnormalities must be worried malignant potential to ductal carcinoma which needs some imaging and pathological examinations for definitive diagnosis and appropriate treatment according to the usual orthotopic breast cancer without delay.

Membranous nephropathy (MN) is a common glomerular disease that is characterized by diffuse thickening of the glomerular basement membrane, and a common cause of nephrotic syndrome (NS). MN is often accompanied with malignant disease; The solid tumors are commonly associated with MN, whereas hematological malignancies are rarely found in patients with MN. A 68-year-old man with a history of diabetes mellitus visited a hospital with a chief complaint of general fatigue. He was previously not diagnosed with any complications of diabetes. Computed tomography revealed a pancreatic tumor, and the pathological findings of the biopsied tumor revealed the tumor was diffuse large B-cell lymphoma (DLBCL). Concurrently, he developed severe proteinuria, hypoalbuminemia, systemic edema and hyperlipidemia, consistent with the diagnosis of NS. The biopsied renal specimen revealed minute spike lesions of glomerular basement membrane, and abnormal lymphocytes infiltrated in the kidney interstitially. Anti-glomerular basement membrane antibody, proteinase-3-/myeloperoxidase antineutrophil cytoplasmic antibody and hepatitis B antigenemia, are absent in the patient. Serum anti-phospholipase A2 receptor (PLA2R) antibody (marker for primary MN) was not detected. A diagnosis of secondary MN induced by DLBCL was made. He received rituximab containing chemotherapy for DLBCL, resulting in amelioration of both DLBCL and MN. We report the rare case of a patient co-existing NS and DLBCL. DLBCL might be pathogenesis of NS; the findings are supported by the presence of MN, an underlying malignancy (DLBCL), and the lack of anti-PLA2R antibodies. Although further investigation is warranted, our case suggests that DLBCL is a possible cause of secondary MN.

Background/aim Locoregional recurrence (LRR) of breast cancer is reported to occur at a rate of 5%-15%. Wide excision of LRR is the recommended treatment, which can increase the probability of subsequent local control. Herein, we describe a surgical technique wherein a pedicled skin and subcutaneous flap close the skin defect after resection of a breast cancer LRR without use of a skin graft. Patients and methods We reviewed four patients who underwent surgical resection using a pedicled rotation flap for chest wall recurrence after mastectomy. Results The surgical margin was set 2 cm apart from the tumor margin. After resection of tumor from the chest wall, we formed an adjacent pedicled flap and rotated the flap to the skin defect. There were no post-operative complications, including wound necrosis. Conclusion Surgical resection with a pedicled rotation flap for post-mastectomy breast cancer LRR is a highly feasible way to achieve complete resection.

Apocrine papillary lesion (APL) is difficult to diagnose as benign or malignant. We experienced an APL remaining in the body for 22 years. We present a case of a 71-year-old woman who had undergone excisional biopsy 22 years previously at the first hospital that she visited. 1 year previously, she had undergone fine-needle aspiration cytology at a second hospital, and the lesion was diagnosed as potentially malignant. She underwent core-needle biopsy at a third hospital, but whether the lesion was benign or malignant could not be definitively diagnosed. We performed right mastectomy and sentinel lymph-node biopsy, because her tumor was suspected to be malignant based on imaging means, and malignancy could not be ruled out on either biopsy or cytology. The histopathological diagnosis was tiny foci of apocrine proliferative lesion with massive hemorrhagic necrosis and no tumor metastasis in two sentinel lymph nodes. Retrospectively, we compared all of the patient’s previous specimens with the present ones, and applied the recent pathological diagnostic criteria. Although the biopsy specimen excised 22 years ago suggested an encapsulated apocrine papillary carcinoma or a papilloma with apocrine ductal carcinoma in situ, neither infiltration nor metastasis has occurred. Furthermore, neither the pathological findings nor the clinical behavior has changed over time.

Objectives This study aimed to investigate the need for medical interpreters, in relation to hospital size, the number of foreign patients accepting, and risk management in municipal hospitals in Japan.Methods In 2016, we conducted a questionnaire survey at 894 municipal hospitals in Japan. The questionnaire included hospital characteristics, the number of foreign patients, the need for medical interpreters, and the respondents' background. We used the incident classification of the Safety Management Council of National University Hospitals (0-5 levels and others). We applied pairwise analysis to hospital size: small hospitals (20-99 beds), medium hospitals (100-399 beds), and large hospitals (400 or more beds).Results The response rates of the small, medium, and large hospital were 30.1%, 32.5%, and 32.8%, respectively. The percentage of hospitals that had accepted foreign patients over the previous year ranged from 84.9% to 97.6%, a higher with larger hospitals. Larger hospitals attended to emergencies, hospitalization, and surgical patients more frequently than the smaller hospitals. Hospital staff who communicated with non-Japanese-speaking foreign patients via ad-hoc interpreters accompanying the patients ranged from 84.3% to 86.7% in larger hospitals. Of the staff at small, medium, and large hospitals, 66.7%, 58.5%, and 44.7%, respectively, considered the interpretations of the ad-hoc interpreters accompanying the patient to be accurate. Of the small, medium, and large hospitals, 31.6%, 76.5% and 92.3% claimed that they would use interpreting services if the interpretation costs were covered by the National Health Insurance System (P0.001). When foreign patients are accepted, 75.7%, 84.7% and 94.6% of small, medium and large hospitals require trained medical interpreters, respectively (P=0.014). Hospital staff reporting that the most common reason for using an interpreter was to reduce medical risks ranged from 81.1% to 94.3%. Of the 274 hospital staff surveyed, 4.7% had experiences of incidents due to the language barriers when dealing with foreign patients. The incident classification was as follows: 3 cases with Impact Level 0, including MRI withdrawal; 9 cases with Level 1, including unauthorized discharge and self-extraction of an in-travenous drip; 1 case of precipitate labor; 1 case of Level 5 death; and 3 other cases. Small hospitals have not been reporting incidents, but larger hospitals, despite the small number of foreign patients, have been reporting incidents.Conclusion Large or medium-sized hospitals need medical interpreters more than smaller hospitals because of the greater number of foreign patients being attended to, and diversity and complexity of reasons for seeking hospital services. Our results suggest that language barriers when dealing with foreign patients are a threat to patient safety. The majority of the responding Japanese municipal hospitals believe that they require trained language interpreters to improve risk management.

Neurofibromatosis type 1 (NF1) is a genetic disorder where affected individuals develop benign or malignant nervous system tumors. To date, NF1 is caused by mutations in the NF1 tumor suppressor gene located at chromosome band 17q11.2. In this study, we aimed to characterize novel recurrent regional chromosomal imbalances and tumor-related candidate genes in NF1-associated cutaneous neurofibromas. Nine cutaneous neurofibromas from NF1 patients were screened for recurrent chromosomal imbalances using high-resolution 400K oligonucleotide array comparative genomic hybridization (aCGH). All the cases exhibited at least one sub-microscopic abnormality. Regions of recurrent chromosomal imbalances in a least one third of cases were loss of 1q13.2 (33%, FAM19A3), 1q21.1 (44%, RABGAP1L), 2q37.1 (56%, INPP5D), 3p25.1 (67%, CHCHD4), 4p15.32 (56%, FGFBP1), 5q11.2 (56%, ARL15), 6q22.31 (56%, NKAIN2), 6q22.33 (67%, ARHGAP18), 6q25.1 (67%, UST), 7q13 (56%, ADCY1), 12q13.13 (44%, KRT71), 19q13.32 (56%, GRLF1), and 20p11.21 (56%, NLP) and gain of 2p23.3 (76%, C2orf53), 8q22.3 (44%, ODF1) and 8q24.3 (67%, ARC). Several chromosomal imbalances, including loss of 7q11.23, 13q14.1, 14q32.13, 17p12, and 17q11.2 were detected at a lower frequency. We also confirmed that these chromosomal imbalances were not detected in the patient-matched lymphocyte DNAs. Amongst the 6 tumor-related candidate genes (RABGAP1L, ADCY1, SLIT2, GRLF1, UST, and ARC) identified in the regions of recurrent chromosomal imbalances, the gene expression changes of UST (down-regulation) and ARC (up-regulation) were found to be significantly associated with copy number alterations. The novel recurrent chromosomal imbalances and the altered expression levels of the tumor-related candidate genes may be associated with the development of NF1-associated benign cutaneous neurofibromas.

This paper compares Japan's university and non-university curriculums for the certified care worker license, and discusses the possibility that the universities' focus on social work education for care workers may result in improving the quality of the workforce and thus the quality of life of older persons in Japan. The demand for professional care workers in Japan is increasing along with demographic changes. In Japan, approximately one-third of direct care workers are nationally licensed as certified care workers (Kaigo-Fukushi-Shi); the rest are unlicensed or are licensed as home helper level 1 or level 2, which licenses are not nationally certified. Most training facilities for certified care workers offer two-year programs, which is the minimum duration of study required by the national Regulations for Designated Training Facilities for Certified Social Workers and Certified Care Workers. Recently, however, an increasing number of universities have begun providing a four-year education for certified...

Aim This study clarified how Japanese nurse administrators consider the current status and future prospects of development and utilization of nurses with specialties. Background The demand for specialized nurses is not satisfied throughout the country. Methods Nine nurse administrators participated in three focus-group discussions. Data were analyzed using qualitative content analysis technique. Results On development of specialized nurses, four categories were abstracted: offering opportunities for career development; establishing an environment of life-term continuous learning; providing well-balanced support for the needs of organizations and individual nurses; and support for career development as a specialist. Conclusions To develop specialized nurses effectively it is important to focus more attention on qualitative aspects of nurses’ professional experience in in-service education and to support appropriate personnel for strategic human resource development. Implications for Nursing Management Facilitating frequent contacts between specialized and general nurses should be highly valued as making an environment where nurses can face career goals daily leads to steady preservation of human resources. It is necessary for nurse administrators to keep human resources quantitatively and to clarify the developmental process after nurses obtain special roles to plan for continuous education.

The migration distance of several scores of dyes in 30% and 4% acetic acid solutions in a horizontal-type apparatus permitting evaporation was measured. In these occasions, an extremely relationship was found to exist between the degree of influence of osmotic flow into filterpaper due to evaporation from the paper surface and the displacement ratios obtained from adsorption analysis with the same filterpaper.
