RÉSUMÉ
Background: The deep inferior epigastric perforator (DIEP) flap is a useful tool for breast reconstruction and tends to be transferred into the breast envelope as the buried flap from an aesthetic point of view. However, it is difficult to monitor the blood flow in the buried DIEP flap after reconstructive microsurgery. Near-infrared spectroscopy devices have recently been used for monitoring the blood flow of various organs. NIRO200NX (Hamamatsu Photonics) continuously measures the tissue oxygen index (TOI) and quickly reflects changes in flap blood flow. In this study, we investigated whether and how much the NIRO200NX applies to monitoring the blood flow of the buried flap. Methods: We included 156 patients who underwent breast reconstruction using a DIEP flap from October 2013 to May 2022, comprising 57 exposed and 99 buried-type DIEP flap cases. We measured TOI using NIRO200NX, in combination with conventional evaluation methods, including color check, pinprick test, and Doppler sound. Results: A criterion of TOI 50 gave the best evaluations. All the 57 exposed-type flap cases showed no false evaluations, and NIRO200NX performed precise judgment. In 99 buried-type flap cases, NIRO200NX correctly evaluated 96 cases. For those buried-type cases, we found only two false-positive and one false-negative case. The misjudgments by NIRO200NX were likely caused by hematoma. Conclusion: We propose NIRO200NX as a reliable device for monitoring the blood flow of the DIEP flap and predicting the outcomes of breast reconstruction by the DIEP flap transfer.

Background: Microporous polysaccharide hemospheres (MPH) are hydrophilic particles administered to reduce the incidence of seroma after mastectomy, but their clinical effectiveness remains controversial. Because a previous randomized, controlled study in a small cohort could not demonstrate the effectiveness of MPH in breast surgery, we evaluated their effectiveness in surgery for breast cancer in a larger cohort. Methods: Medical records of 352 patients who underwent total mastectomy for breast cancer were retrospectively reviewed. Clinical data were compared between 126 patients who received MPH during surgery (MPH group) and 226 who did not (control group) according to surgical procedures. Patients were significantly older in the MPH group than in the control group because of selection bias, but other factors, such as body mass index and number of dissected lymph nodes, did not differ between groups. Results: When analyzed by use of axillary manipulation, the drain placement period and drainage volume were significantly less in the MPH group than in the control group for patients with mastectomy and sentinel lymph node biopsy. Only drainage volume was significantly less in the MPH group for patients with mastectomy and axillary lymph node dissection. The frequency of total postoperative complications, such as seroma requiring puncture, did not differ between groups. Conclusions: Use of MPH may decrease the postoperative drainage volume and drain placement period in mastectomy for patients with breast cancer.

OBJECTIVE: We aimed to evaluate a proposed conceptual framework for quality assessment of medical interpretation using actual data from clinical settings. METHODS: A mixed methods approach was used. Routine outpatient encounters involving Portuguese-speaking Brazilian patients, Japanese physicians, and hospital-provided and ad hoc interpreters were digitally recorded and transcribed. A questionnaire survey examining participants' satisfaction was conducted; 111 and 13 encounters by hospital-provided and ad hoc interpreters, respectively, were recorded. Segments of consecutively interpreted utterances were coded as "altered," whereby the interpreter changed the meaning of the source utterance, or "unaltered (accurate)." Frequency and type of alteration were analyzed. The effect of positive interpretation alterations on physician-patient interactions was qualitatively described. RESULTS: Interpretation accuracy was significantly higher for hospital-provided interpreters, but was not associated with overall patient satisfaction. Overall physician satisfaction was associated with accurate interpretation, clinically negative altered interpretations, and positive voluntary interventions (p < 0.05). Positive alterations promoted patient, physician, and interpreter interactions, which helped to achieve clinical outcomes. CONCLUSION: A new conceptual framework for quality assessment of medical interpretation was developed for clinical settings. Healthcare provider satisfaction can provide a measure of interpretation alterations. PRACTICE IMPLICATIONS: Healthcare providers can effectively use the conceptual framework to improve medical interpretation and collaboration with healthcare interpreters.

BACKGROUND: Delays in breast cancer diagnosis can allow the disease to progress to an incurable stage. However, factors that cause patients to delay seeking treatment are unclear. In this study, we aimed to identify behavioral economic factors and personality characteristics of patients with breast cancer who had a delayed diagnosis. METHODS: We analyzed questionnaires completed by 41 patients with breast cancer. A delayed diagnosis was defined if the time between the first symptom and the medical visit was more than 6 months. RESULTS: We found 11 patients who had a delayed diagnosis. The significant characteristics associated with patients with breast cancer who had delayed diagnosis were: (i) less experience with breast cancer screening; (ii) progressive disease stage; and (iii) low time and future time preference. We found no significant behavioral economic factors other than time preference, and personality that differed between patients with breast cancer who did and did not have a delayed diagnosis. CONCLUSION: Low time preference rate is a characteristic of patients with breast cancer who had a delayed diagnosis.

BACKGROUND: It is quite rare for breast cancer to metastasize to the kidney with a tumor thrombus in the inferior vena cava. CASE PRESENTATION: A Japanese woman in her forties was diagnosed with cancer of the left breast and underwent left mastectomy with sentinel lymph node biopsy. The final pathological diagnosis was pT1aN0M0, stage IA (ER positive, PgR positive, HER2 negative). Thirteen years later, she presented for care with the complaint of abdominal pain. By imaging findings, right renal carcinoma with a tumor thrombus in the inferior vena cava and lung metastases was suspected. However, her tumors were refractory to molecular targeted therapy. In addition, CT-guided needle biopsy of the kidney and lung lesions was done and it was revealed that lesions of the left lung and the right kidney was breast cancer metastases (ER positive, PgR positive, HER2 negative). The patient started combination therapy consisting of abemaciclib, tamoxifen and leuprorelin. Six months later, she died from progression of her metastatic disease. CONCLUSIONS: It is sometimes difficult to differentiate between primary renal cancer and kidney metastases from breast cancer on imaging. Renal biopsy is recommended before commencing treatment.

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.

PURPOSE: In endoscopic surgery, surgeons occasionally encounter difficulties due to visual field obstruction by muscles or blood vessels. In these situations, specialized instruments that can effectively retract these obstructions are required. Recently, we developed a new detachable wire-rimmed retractor (KN retractor) for narrow-space surgery. METHODS: We evaluated the utility of this KN retractor in 15 patients with thyroid and parathyroid disease. Of those, five patients with papillary thyroid cancer had gasless endoscopic hemithyroidectomy with central node dissection, five underwent endoscopic total thyroidectomy for Graves' disease, and the remaining five received endoscopic parathyroidectomy with gas insufflation. RESULTS: Surgeons were able to perform meticulous operations in a satisfactory visual field supported by the KN retractor. In all patients, the strap muscles were preserved without cutting. The average operating time was 149, 154, and 81 min in patients who underwent hemithyroidectomy with central node dissection, total thyroidectomy, and parathyroidectomy, respectively. Gas insufflation was successfully completed in all cases while maintaining sufficient airtightness. CONCLUSIONS: The KN retractor is suitable for both the gasless lifting method and gas insufflation surgery in a narrow space. We believe that the KN retractor is a new device that will greatly improve the safety and shorten the operation time in endoscopic surgery.

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.

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-1positive patients were significantly older than HTLV-1negative 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.

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.

ObjectivesãThis 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.MethodsãIn 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).ResultsãThe 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 (P<0.001). 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.ConclusionãLarge 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.

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.
