OBJECTIVE: Obesity adversely impacts breast cancer treatment and outcomes. This study assessed the efficacy of nurses' motivational interviews (MI) in promoting weight loss among breast cancer patients. METHODS: Motivational Interviewing was performed at 4, 8, and 12 weeks from baseline in 27 overweight/ obese breast cancer patients receiving adjuvant endocrine therapy. An average weight loss rate of 5% at week 12 was the threshold for determining whether MI intervention was clinically meaningful...

Low-grade endometrial stromal sarcoma (LG-ESS) is a rare uterine neoplasm. Computed tomography (CT) revealed the presence of multiple small bilateral pulmonary nodules in a 58-year-old woman 1 year after surgery for LG-ESS; the clinical diagnosis was pulmonary metastasis. Hormone therapy with progesterone was initiated, after which most of the solid nodules disappeared and some transformed into cystic lesions. Seven years after hormone therapy, the patient experienced repeated pneumothorax. The cause of the pneumothorax was perforation of a metastatic focus within the wall of a small subpleural cyst that was not evident on CT images...

Transverse testicular ectopia (TTE) is a rare congenital malformation where both testes descend through the same inguinal canal and are located in the same hemiscrotum. It is usually treated with transseptal orchiopexy. In this article, we report the case of a 1-year-old boy diagnosed with TTE who was successfully treated with laparoscopically assisted orchiopexy by going through the anatomical conventional route. A four-month-old boy was referred to our department with bilateral empty scrotum. On the physical examination, the left testis was palpable in the left groin region and the right testis was impalpable...

Angiosarcoma is a rare malignant tumor of endothelial origin. It is an aggressive neoplasm with early metastasis and poor prognosis and accounts for approximately 2% of all soft tissue sarcomas. Primary tumors arising in the oral cavity account for only 1% of all angiosarcomas. Here, we report a rare case of metastatic angiosarcoma of the gingiva originating from a primary mediastinal lesion. The patient was an 83-year-old man who presented with a maxillary interincisor tumor; it was a painless mass with rounded superficial necrosis measuring 23 mm× 17 mm on the labial side and 20 mm× 17 mm on the palatal side...

Generalized pustular psoriasis (GPP) is a disease that presents with fever and multiple sterile pustules on flushed skin all over the body. GPP should be considered as systemic inflammatory response syndrome (SIRS), and is occasionally associated with respiratory failure. We encountered a case of GPP with organizing pneumonia (OP) during treatment for rheumatoid arthritis (RA). A 74-year-old Japanese woman with RA developed fever and erythema with small pustules on the trunk and extremities. She was diagnosed as GPP and admitted to our hospital...

A 75-year-old male visited our hospital with bilateral hilar lymph node swelling detected on chest radiography during an annual medical checkup. Chest computed tomography revealed swelling of multiple hilar mediastinal lymph nodes. Histopathological and immunohistochemical examinations of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) specimens from the hilar lymph nodes revealed amyloid deposition. Bilateral hilar and mediastinal lymphadenopathies can be the first manifestations of amyloidosis diagnosed using EBUS-TBNA...

We report a case of chronic infection with Pasteurella multocida in the lower respiratory tract in a man with a cat. A 77-year-old man presented with recurrent hemoptysis accompanied by bronchiectasis and an opacity in the left lung on chest computed tomography. Although the patient was seropositive for Mycobacterium avium complex, repeated sputum cultures were negative for any specific pathogen. Three years later, he was referred to our hospital for hemoptysis with enhanced opacity in the lower lobe of the left lung...

In epithelial tissues, intercellular adhesion structures are formed between adjacent cells via intercellular adhesion factors, such as zonula occludens (ZO-1), to maintain the structure and function of tissues and organs, thereby contributing to homeostasis. Epithelial cells are polarized into apical and basal regions by tight junctions (TJs), a type of intercellular adhesion structure, and thus, their intracellular organelles are asymmetrically distributed. Normal epithelial cells maintain their cellular function by controlling cytoskeletal reorganization, motility, and division by maintaining asymmetry in their intracellular organelles...

Ecchymosis is a common side effect after injury and surgery. A pulsed dye laser (PDL) is the gold standard for vascular lesions and can minimize ecchymosis. Heating induces hemoglobin modification due to oxidative and heat reactions with the formation of bilirubin and methemoglobin, resulting in color changes to brown-yellow. Therefore, downtime following cosmetic procedures can be shortened.

The differential diagnosis of a tongue mass containing calcified bodies includes a phlebolith associated with vascular lesions, such as hemangioma and vascular malformation, and diseases such as neoplasm, osseous choristoma and hypercalcemic states, including hyperparathyroidism. The appearance of the calcified bodies on plain radiographs may help to differentiate these entities. Computed tomography, magnetic resonance imaging, and ultrasonography are also useful for differentiating these soft tissue lesions...

A 43-year-old Japanese man who had suffered psoriasis vulgaris for eight years visited our hospital. His comorbidities were dyslipidemia, hyperuricemia, and obesity. He received phototherapy for six months, which did not result in improvement. Following treatment with brodalumab, his skin symptoms improved. However, seven months after brodalumab treatment, he received two doses of the mRNA-1273 COVID-19 vaccine, with a one-month interval between doses. One month following the second vaccination, his skin symptoms were exacerbated...

OBJECTIVE: We investigated the association between pancreatic cysts and cystic diseases of other organs using abdominal ultrasonography in patients undergoing medical checkup. METHODS: Between April 2021 and March 2022, 4496 patients had a comprehensive medical checkup at our hospital, which included abdominal ultrasonography. RESULTS: Among 4496 patients, 172 (3.8%), 1592 (35.4%), and 1425 (31.7%) had pancreatic, liver, and renal cysts, respectively...

OBJECTIVE: In the present retrospective study, we evaluated potentially predictive factors and determined receiver operating characteristic (ROC) curve cut-off values for effective detection of patients at higher risk of re-hospitalization due to postoperative infection after total laparoscopic hysterectomy. MATERIALS AND METHODS: We included 168 patients who had undergone laparoscopic hysterectomy. Data were collected from medical records. Patients were classified into non-infection (n = 161) and infection (n = 7) groups based on whether they developed fever after hospital discharge...

OBJECTIVE: This study aimed to investigate how respiratory status may be affected during meal consumption in patients with acute pneumonia, mainly aspiration pneumonia, using percutaneous oxygen saturation (SpO2 ) and pulse rate (PR) measurements. METHODS: We recruited 44 inpatients at the Towada City Hospital and divided them into 'pneumonia' and 'control' groups. Generalized linear mixed effects model was used for analysis. The pneumonia group comprised 22 patients (mean age 81...

OBJECTIVE: Recently, excessive and off-label prescribing of psychotropic drugs for children and adolescents have become a problem. Child and adolescent psychiatric patients receive treatment in many departments and department-specific psychotropic drug use has not been analyzed. We surveyed prescriptions for child and adolescent psychiatric outpatients during their first year of treatment. METHODS: The participants were 302 patients, 15 years or younger, who made their first visit to the outpatient psychiatry department of Tokai University Hospital from September 1, 2015 to September 1, 2016...

Radiation-induced hemorrhagic cystitis is a late complication of radiotherapy, and in rare cases, refractory. Refractory bleeding may not be resolved by transurethral electrocoagulation (TUEC) or hyperbaric oxygen (HBO) therapy and requires transcatheter arterial embolization (TAE) or urinary diversion. Here, we report two cases of radiation-induced hemorrhagic cystitis successfully treated with TAE. Case 1 was a 61-yearold man who underwent total prostatectomy for prostate cancer followed by salvage radiation therapy...

OBJECTIVE: To evaluate the optical performance of plate-haptic rotationally asymmetric refractive multifocal intraocular lenses (IOLs) with +1.5 D addition power by reproducing calcium deposition using rabbit eyes. METHODS: Five IOLs (LS-313 MF15 [Santen/Teleon], W-60R [Santen], NS1 [KOWA], SY60WF [Alcon], and NS-60YS [NIDEK]) with varying water content were randomly implanted in rabbit eyes. Cell proliferation in the lens capsule and deposits on the IOL surface were confirmed with a slit lamp...

OBJECTIVE: Magnetic resonance thoracic ductography (MRTD), concomitant with blood vessel imaging, provides useful anatomical information. The purpose of this study was to assess the visibility of the thoracic duct and blood vessels simultaneously by MRTD using balanced turbo-field-echo (bTFE) and turbo spin-echo (TSE). METHODS: MRTDs concomitant with blood vessel imaging on bTFE and TSE were obtained for 10 healthy volunteers with a 1.5T-magnetic resonance unit...

Ataxia telangiectasia (AT) is a rare autosomal recessive disorder caused by the pathological variants of the ATM gene. Owing to i ts r arity a nd n ature, complications of AT, such a s malignant tumors, a re often difficult to manage with standard imaging studies and treatments, and there are no established management strategies. We report the case of a woman who had AT in childhood and developed breast cancer in her 20s; the disease was successfully managed by the decision-making of multidisciplinary physicians professionals with ethics support...

Nodular pulmonary amyloidosis, a subtype of pulmonary amyloidosis, is a unique disease that can mimic lung cancer on radiographic imaging and is related to lymphoproliferative disorders. In this report, we describe a case of a 76-year-old male who presented with a solitary nodule in his left lower lung lobe on computed tomography that increased from 6 mm to 13 mm in diameter over 40 months. Lung cancer was suspected; however, transbronchial lung biopsy revealed deposition of an eosinophilic and homogeneous amorphous substance, which showed apple-green birefringence under polarized light after Congo red staining, and immunohistochemistry analysis returned positive results for immunoglobulin lambda light-chain...
