    Abstract Urothelial carcinoma (UC) is an umbrella term for bladder cancers (BCa) and upper-tract urothelial carcinoma (UTUC), with BCa and UTUC sometimes detected concomitantly. The methods of detection for UC are often inaccurate or highly invasive, and, therefore, are thought to be unsatisfactory. Previously, we reported seven serum miRNAs as diagnostic markers for BCa. Here, we re-evaluated potential diagnostic miRNAs in different institutions. We prospectively analyzed serum samples obtained from 126 UC patients (BCa: 106 samples; UTUC: 14 samples; UTUC with BCa: six samples) and 50 noncancer controls by microarray analysis. We randomly assigned these samples into a training or a validation set. Biomarker candidate miRNAs were selected based on cross-validation scores in the training set of samples, with diagnostic power confirmed in the validation set. Among the diagnostic miRNAs identified in this way, miR-1343-5p and miR-6087 had been identified as potential diagnostic miRNAs in our previous study. In addition, we evaluated the association between the serum levels of identified miRNAs and the presence of UC risk conditions. The expression levels of several miRNAs correlate with the risk factors in participants without UC, which may be explained by the presence of a microscopic tumor or a precancerous lesion. In conclusion, we identified two robust miRNA diagnostic markers for UC detection. Further functional analysis is required to elucidate the mechanism by which alterations in the expression of these miRNAs occur.

    Abstract Surgical invasion is a risk factor of pyoderma gangrenosum (PG). A total of 25% of postoperative PG cases were reported to occur after breast surgeries, including bilateral breast reduction and breast reconstruction following cancer resection. Immunosuppressive therapy and less-invasive wound therapy are necessary; however, the complete healing of ulcers takes 5.1 months on average. We herein report a case of skin grafting under a surgical concept of less-invasive and short-term treatment. An 82-year-old woman complained of a high fever and severe pain at her breast wounds after bilateral breast cancer resection. Although we performed emergency debridement surgery to remove the necrotic tissue, suspecting surgical site infection and inflammation, her high fever persisted. She was diagnosed with PG because of the physical findings of characteristic painful, sterile ulcerations, bullae and pustules, and the pathological abundance of neutrophils in the absence of infection and vasculitis. Oral administration of prednisolone 30 mg/day improved the symptoms, and we applied negative-pressure wound therapy (NPWT) from day 16 following debridement surgery. After the gradual reduction of oral steroid intake to 12.5 mg/day, we performed skin grafting surgery. To limit the surgical invasion, we used the surplus skin around the ulcers. Split-thickness mesh skin grafts were fixed by NPWT to avoid the use of tie-over sutures. We achieved short-term treatment of PG with a less-invasive surgical strategy using skin around the ulcers and NPWT.

    Abstract Foreign body in the bladder is a relatively rare case. We encountered two cases of foreign bodies in the bladder after gynecological surgery. Case 1 was a 72-year-old woman. When she was 70 years old,an operation for her pelvic organ prolapse was performed. She visited our hospital because of discomfort in urination. We performed a transurethral lithotripsy of the bladder stone and detected a foreign body,and it was an anchor used for the Tissue Fixation System(TFS)operation (a pelvic organ prolapse operation). Case 2 was a 34-year-old woman. She delivered a baby by Caesarean section when she was 30 years old. She visited our hospital because of recurring urinary tract infection. The ultrasound examination of the bladder showed high echoic area in the posterior bladder wall. The cystoscope examination showed a small black foreign body that was protruding from the posterior wall of the bladder. The foreign body in the bladder was a surgical suture. The component of the suture was similar to silk. The foreign body in the bladder may have been the cause of infection. Artificial material used for an operation of an organ in the pelvic area sometimes slips into the bladder and causes inflammation. If a patient had undergone an operation for an organ in the pelvic area in the past,and there is recurring urinary tract infection,the presence of a foreign body in the bladder should be suspected.

    Abstract Background: Aspergillosis in patients with impaired immunity usually presents with invasive pulmonary infection and dissemination to a variety of organs via hematogenous spread. Aspergilloma in the retroperitoneal cavity is a rare disease with only a few cases reported in the literature. To the best of our knowledge, the present case of a retroperitoneal aspergilloma with no surgical history is only the second report in the literature.
    Case presentation: A 65 year-old man, who had been receiving immunosuppressive treatment for rheumatoid arthritis with vasculitis for 9 years, was referred to the Urology Department with a retroperitoneal mass. This was confirmed by computed tomography performed during treatment for pulmonary aspergilloma. Because it was not possible to rule out malignant disease (e.g., liposarcoma), surgical exploration was performed. Pathological examination revealed aspergillus hyphae with fat necrosis, and retroperitoneal aspergilloma was diagnosed and appropriately treated. The tumor did not recur subsequently.
    Conclusion: Our present case emphasizes that pharmacological treatments for aspergilloma in the retroperitoneal cavity have poor drug transitivity, so the relative effectiveness of pharmacological response is not useful for differentiating retroperitoneal aspergilloma from malignant disease.

    Abstract A cat was referred because of diffuse parenchymal lung disease. Close examinations revealed a swollen abdominal lymph node and multiple nodules of the liver. Mycobacterium avium subspecies hominissuis infection was confirmed by culture and single nucleotide polymorphism analysis of samples recovered from the liver and bronchoalveolar lavage. After administration of combination antibiotics for 6 months, culture results were negative. Though atonic seizures were observed during the treatment, it disappeared after isoniazid discontinuation and pyridoxal phosphate administration. On day 771 of illness, no clinical signs, lung diseases, or obvious swelling of lymph nodes was observed. This is the first report to confirm Mycobacterium avium subspecies hominissuis infection in cats through gene analysis and to completely cure it with combination antibiotics.

    Abstract Computed tomography (CT) performed for a 75-year-old man as a follow-up examination for deep vein thrombosis in October 2010 revealed a left adrenal mass (diameter, 8 mm). In December 2012, the adrenal mass increased to 28 mm in diameter, and he was referred to our department. Several blood examinations revealed that the adrenal mass was non-functioning, and only peripheral lesions were observed to be enhanced by using CT in the arterial phase. Malignancy was suspected due to the irregular shape and growth of the mass, and left adrenalectomy was performed in February 2013. The histopathological diagnosis was adrenal mycobacteriosis, and clinical diagnosis was adrenal tuberculosis. No other tuberculosis infection-related lesion was detected, and the patient was treated with multidrug antituberculous chemotherapy.

    Abstract The management of acute scrotum can be challenging, especially in infants or patients with a neurological or neurodevelopmental disorder in whom presentation, diagnosis and definitive management tends to be delayed. This leads to poor outcomes, such as loss of the affected testis. Here we present two cases of testicular torsion in patients with neurodevelopmental disorders, and a further two cases of epidydimo-orchitis in whom measurement of CD64 expression on neutrophils was helpful for differential diagnosis. These data suggest that the levels of expression of CD64 by neutrophils, known as a marker of infection, could also be useful for differentiating between testicular torsion and infection in acute scrotum.

    Abstract We report a case of dedifferentiated liposarcoma of the spermatic cord. A 79-year-old man was referred to our hospital with the chief complaint of a painless right scrotal swelling. A hard mass was palpable beside the soft mass which was suspected of lipoma or liposarcoma, and under this mass there was right testis. Therefore, we performed a right radical orciectomy. Histopathological diagnosis was dedifferentiated liposarcoma of the spermatic cord. Dedifferentiated liposarcoma of the spermatic cord was rare, and preoperative diagnosis was difficult.

    Abstract Abstract Background Patients with spinal cord injury and a chronic indwelling urinary catheter are known to have an increased risk of bladder malignancy. However, squamous cell carcinoma (SCC) of the epidermis around a suprapubic cystostomy is relatively rare. Here, we report a case of lower abdominal SCC arising from the suprapubic cystostomy tract. Case presentation A 58-year-old man with a complete spinal cord injury was referred to our hospital with a chief complaint of an abdominal mass. Abdominal enhanced computed tomography (CT) showed a 7-cm mass surrounding the suprapubic cystostomy and bilateral inguinal and para-aortic lymph nodes metastasis. Histopathological examination of percutaneous biopsy specimens was performed. The diagnosis was stage IV (cT4N1M1) epidermal SCC, which was treated with palliative external radiation therapy. Conclusion The SCC in this case was thought to arise from mechanical stimulus of the suprapubic cystostomy. Physicians and patients should pay careful attention to any signs of neoplasms with long-term indwelling catheters, such as skin changes around the suprapubic cystostomy site. This case presentation is only the fourth report of SCC arising from the suprapubic cystostomy tract in the literature. In cases of unresectable tumors and contraindications to chemotherapy, palliative radiotherapy may lead to disease remission and symptom relief.
