Hemangioblastoma tends to occur in the infratentorial regions and rarely in the supratentorial regions. This tumor is strongly associated with von Hippel-Lindau disease (VHLD), especially in the supratentorial regions, with only 12 cases of suprasellar hemangioblastoma unrelated to VHLD. However, all these cases were diagnosed based on clinical screening and confirmation of family history. We report a case of suprasellar hemangioblastoma that was successfully removed through an extended transsphenoidal approach and diagnosed as a sporadic case unrelated to VHLD by immunohistochemical examination. A 67-year-old woman had mild diabetes insipidus and a visual field defect. Head magnetic resonance imaging revealed a suprasellar tumor compressing the optic chiasm upward. The tumor was totally removed without complication through an extended transsphenoidal approach. Postoperative histologic examination disclosed large vacuolated stromal cells and rich capillary networks, and the diagnosis was established as hemangioblastoma. Clinical screening and confirmation of family history revealed no specific results, and additional immunohistochemical staining showed diffuse cytoplasmic expression of anti-VHLD gene-derived protein (pVHL). We emphasize that pVHL immunohistochemical evaluation would be wise to adopt, especially for patients with a high risk of VHLD related to younger age and supratentorial lesions.

Purpose: Although serum hyaluronan (HA) levels increase in patients with osteoarthritis (OA), the association between OA severity and elevation of serum HA levels is not clear. Our purpose was to investigate the relationship between serum HA levels and OA in various anatomical sites and to detect which joints are strongly correlated with elevated serum HA levels. Methods: Seven hundred and ten individuals from the general population who participated in the Iwaki Health Promotion Project in 2008 were involved. Kellgren-Lawrence grade 2 or higher in the knee, hip, lumbar spine, finger and wrist was defined as OA. Serum HA levels were determined on the same day. Spearman's correlation coefficients between serum HA levels and total number of joints affected by OA were calculated. Linear regression was analysed with serum HA levels as the independent variable; age, gender, presence of OA and intake of supplements were used as dependent variables. Results: Prevalence of knee OA was 30.7 %, hip 16.8 %, lumbar spine 65.1 %, wrist 9.0 % and finger 22.0 %. Serum HA levels had a positive correlation with the number of involved joints, and the correlation coefficient was 0.410 (p < 0.001). Serum HA was significantly affected by age (β = 0.382), knee OA (β = 0.163) and finger OA (β = 0.164). Conclusion: Although this biomarker reflects a systemic condition, higher serum HA levels were associated with total number of OA joints. Knee and finger OA were key joints related to increased serum HA levels. These results are valuable in understanding characteristics of serum HA levels as a biomarker for osteoarthritis. © 2013 Springer-Verlag Berlin Heidelberg.

A 76-year-old man was admitted to our hospital for the treatment of remnant gastric cancer. Laparotomy revealed massive lymph node metastasis, direct invasion of the transverse colon, and peritoneal dissemination. Partial resection of remnant stomach with transverse colon and intraperitoneal infuser port implantation were performed. After surgery, he underwent chemotherapy with docetaxel (DOC) administered intraperitoneally, and S-1. CT scan showed no tumors, and the patient was judged to be a complete response (CR) without serious adverse events. We switched DOC to intravenous injection because of port damage, and grade 3 adverse events appeared frequently until the chemotherapy was stopped. It has been 30 months since we stopped the chemotherapy, and the patient is still alive with no evidence of tumor recurrence 48 months after surgery.

Background: We investigated the association between long-segment Barrett's esophagus and obesity in the Japanese population in a multicenter case-control trial. Methods: One hundred thirteen patients with endoscopically detected Barrett's esophagus with a length of more than 2 cm and the same number of sex-and age-matched controls were prospectively enrolled. Barrett's esophagus was diagnosed based on the Prague C and M criteria. The body mass index (BMI) of the subjects was categorized into the following groups: normal, BMI <22.9; overweight, BMI 23.0-24.9, and obese, BMI >25.0. To determine the association between BMI and the risk of Barrett's esophagus, multivariate logistic regression analyses were performed. Results: The basically adjusted regression model adjusted for smoking and alcohol consumption revealed that overweight and obesity were significantly associated with an elevated risk of Barrett's esophagus (OR 2.4, 95% CI 1.2-4.7, and OR 2.5, 95% CI 1.3-4.6, respectively). The intensity of the association was not attenuated even after adjustment for gastroesophageal reflux disease-related parameters. Conclusions: An increased BMI was associated with an increased risk for Barrett's esophagus through a gastroesophageal reflux-independent mechanism in the Japanese population. Further, unlike in Caucasian populations, being even slightly overweight with a BMI of 23.0-24.9 was an independent risk factor in the Japanese population. © 2014 S. Karger AG, Basel.

A 44-year-old man discovered a swollen right testis more than 4 years earlier. He was brought to our hospital because of abdominal pain and vomiting. Enhanced computed tomography (CT) showed a swollen right testis, lung nodules, and swollen retroperitoneal and mediastinal lymph nodes. The swollen lymph nodes compressed the duodenum, causing ileus. HCG, HCG-β and AFP levels were normal, but the LDH level was high (2,933 IU/L). A diagnosis of testicular cancer with lung and lymph node metastases was made, and a right orchidectomy was performed. However, the pathological diagnosis was unclear, and it was necessary to consult another pathologist, but this took 6 weeks. While awaiting the pathological diagnosis, the patient was given chemotherapy with two 3-week courses of BEP. On pathological examination, the tumor consisted of small round cells with a rosette-like arrangement. Cartilage and keratinized tissues were also present. Immunohistochemical staining was positive for CD 56, synaptophysin, vimentin, GFAP, and CD99(MIC2), but negative for AE1/AE3, OCT4, chromogranin, INI-1, and desmin. The patient was then diagnosed as having a primitive neuroectodermal tumor and teratoma. The metastatic lymph nodes decreased in size after chemotherapy; therefore, two further courses of BEP were added. However, CT showed disease progression. The patient refused further therapy and returned home. Eight months later, he was hospitalized because of swollen retroperitoneal and mediastinal lymph nodes and ileus. Despite treatment with radiation therapy, which resulted in decreased lymph nodes, the patient died. This was a very rare case, the first such case in Japan. © 2015 The Japanese Urological Association.
