Mixed high-grade serous and large cell neuroendocrine carcinoma arising from rectal endometriosis 11 years after hysterectomy.

The malignant gastrointestinal endometriosis transformation is represented by endometriosis-associated intestinal tumors. Endometrioid adenocarcinoma and clear cell adenocarcinoma are most common among the endometrial cancers of all organs. Only four cases of mixed serous carcinoma and large cell neuroendocrine carcinoma have been reported, and all these cases originated from the uterus. A 59-year-old woman with a month's history of bloody stools was admitted. She was stable until the hematochezia occurred but is 11 years post-hysterectomy. A circumferential type-3 advanced upper rectum tumor was seen on colonoscopy. Adenocarcinoma was revealed from the forceps biopsies of the type-3 tumor component. Computed tomography showed narrowed lumen with a thickened rectum wall, a continuing mass, and a component on the anorectal side. Swollen lymph nodes were observed around the rectum, but no distant metastatic lymph nodes or organs were found. To treat the lesion, rectal surgical resection with D3 lymph node dissection was performed. Histological examination revealed combined high-grade serous and large cell neuroendocrine carcinomas. Tumor was contiguous to the endometrium in the sub-serosa. Endometriosis was determined to be the origin of both carcinomas. Therefore, endometriosis-associated intestinal tumors should be included in the differential diagnosis when rectal tumors with cystic structures are found post-hysterectomy.

Retroperitoneal liposarcoma with pancreatic metastasis and gastric cancer: a case report.

On computed tomography scanning, a 63-year-old man with vomiting and anorexia was discovered to have a mass in the pancreatic body and a retroperitoneal mass extending to the right lobe of the liver. An esophagogastroduodenoscopy revealed an advanced gastric carcinoma in the middle gastric body, and a biopsy specimen revealed a poorly differentiated adenocarcinoma. The pancreatic and retroperitoneal masses were considered metastatic lesions of gastric cancer, and a biopsy was taken from the pancreatic lesion using endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). The histology of the EUS-FNA pancreatic specimen revealed atypical spindle-shaped cells and increased stromal collagen fibrosis, and liposarcoma was considered. Conversely, a percutaneous ultrasound-guided biopsy was taken for the retroperitoneal lesion, and the histology revealed that it was a dedifferentiated liposarcoma. On the basis of histopathological and imaging findings, the retroperitoneal liposarcoma was identified as the primary lesion, the pancreatic lesion as a metastasis of the primary liposarcoma, and the gastric carcinoma as an independent tumor. As far as we know, there have only been three reports of metastatic pancreatic liposarcoma diagnosed via EUS-FNA. In this case, the patient also had gastric cancer, and EUS-FNA was helpful in differentiating metastatic pancreatic tumors from gastric cancer.

[A case of ferroportin disease with phenotype A gene mutation in SCL40A1 resembling phenotype B manifestation influenced by alcohol consumption].

A 57-year-old man had been detected to have an elevated transaminase level. He had a history of alcohol consumption, and abdominal ultrasonography revealed an increase in the echogenicity of the liver;hence, he was diagnosed as having alcoholic liver disease. He restricted his alcohol intake, but the elevated transaminase level did not improve. Further medical examination was performed. He was found to have hyperferritinemia (serum ferritin, 6574ng/mL) and high transferrin saturation (TSAT, 90.5%). Computed tomography (CT) revealed high CT values of the liver and spleen (94 and 84HU, respectively). These findings differed from the characteristics of a typical alcoholic liver disease. Liver biopsy revealed iron deposition within the hepatocytes and Kupffer cells and liver fibrosis (F1-2). From the gene analysis of HFE, HJV, TFR2, HAMP, and SLC40A1 genes, he was heterozygous for the G>A (G490D) mutation in the ferroportin gene (SLC40A1). He was diagnosed as having ferroportin disease. It was reported that patients with a G490D mutation exhibited ferroportin disease A, which occurs owing to a loss-of-function mutation of SLC40A1. However, he was considered to have some characteristics of ferroportin disease B, which occurs owing to a gain-of-function mutation of SLC40A1. In this case, alcohol consumption might affect the progression of iron deposition in the liver. Therapeutic venesection was performed, and his hyperferritinemia with high TSAT gradually improved. In the course of the disease, other organ damages and progression of liver fibrosis did not occur.

Hospital Staff Shortage after the 2011 Triple Disaster in Fukushima, Japan-An Earthquake, Tsunamis, and Nuclear Power Plant Accident: A Case of the Soso District.

INTRODUCTION: In 2011, Fukushima was struck by a triple disaster: an earthquake, tsunamis, and a nuclear accident. In the aftermath, there was much fear among hospital staff members about radiation exposure and many staff members failed to report to work. OBJECTIVES: One objective is to measure this shortage in hospital staff and another is to compare the difference in recovery by hospital types and by categories of hospital staff. DESIGN: The monthly records of the number of staff members from May 2011 to September 2012 were extracted anonymously from the records of 7 local hospitals in the Soso district in Fukushima. Change in the number of staff was analyzed. RESULTS: Staff shortages at hospitals reached a maximum within one month after the disaster (47% reported to work). The shortage of clerks was the most severe (38% reported to work), followed by nurses (48% reported to work). The shortages remained even 18 months after the disaster. CONCLUSION: After a disaster in which the damage to hospital functions surpasses the structural damage, massive support of human resources in the acute phase and a smaller volume of support in the mid-term phase appear to be required, particularly for non-medical staff.

Primary rectal mucosa-associated lymphoid tissue lymphoma in a patient with previously identified primary biliary cirrhosis and secondary Sjögren's syndrome.

An 83-year-old female began treatment with prednisolone and ursodeoxycholic acid at 62 years of age, following a diagnosis of primary biliary cirrhosis (PBC) and secondary Sjögren's syndrome (SjS). With persisting bloody stools, the patient underwent colonoscopy at 83 years of age. Histopathological evaluation revealed mucosa-associated lymphoid tissue (MALT) lymphoma. The elevated rectal lesion resolved with rituximab treatment. We report this case because although patients with SjS are at increased risk of malignant lymphoma, primary rectal MALT lymphoma is very uncommon in association with PBC and secondary SjS.

[Pharmaceutical Service after the Fukushima Disaster: A Case Report of Soma General Hospital].

  Despite being damaged by the 2011 Tohoku earthquake, tsunami, and nuclear disaster, Soma General Hospital, located approximately 40 km north of Fukushima Daiichi nuclear power plant, was able to fulfill its role as a key regional hospital in northeast Fukushima. To elucidate the pharmaceutical service in response to the disaster, we investigated the hospital's operations in 2011 according to the medical records and prescriptions. One of the difficulties that the department of pharmaceutical service faced at that time was the increase in emergency healthcare requests by evacuated patients from other hospitals and clinics. Herein, we propose the following countermeasures to be considered in future disaster preparations: (1) establishing a medical and pharmaceutical service coordinator for disaster relief; (2) sharing all local patients' medical information in emergencies (at least contraindicated drugs or allergy history); and (3) reviewing disaster stockpiles, especially pharmaceuticals (both at the hospital and in nearby locations).

Mental Health Crisis in Northeast Fukushima after the 2011 Earthquake, Tsunami and Nuclear Disaster.

The great earthquake of 11 March 2011 and resulting tsunami caused serious damage to various areas of the Pacific coast in northeast Fukushima, and all the residents faced fears of meltdown of the reactors at the Fukushima Daiichi Nuclear Power Plant. One of the most seriously affected areas was the district of Soso, located in the northeast part of Fukushima prefecture, with 12 municipalities (Soma City, Minamisoma City, Shinchi Town, Namie Town, Futaba Town, Okuma Town, Tomioka Town, Naraha Town, Hirono Town, Iitate Village, Katsurao Village and Kawauchi Village). The district of Soso is home to approximately 200,000 residents, many of whom were seriously affected by the threefold disaster. During the subsequent four years, the population of Soso decreased by nearly 10%. In March 2011 before the disaster, five hospitals and two clinics for psychiatric patients, along with 712 inpatients, were operating in the district of Soso. However, as of March 2015, there were only one hospital and three clinics, along with approximately 50 inpatients, although a new mental health clinic in Soma City was opened in 2012 for supporting victims suffering from the disaster. We hereby suggest that the patients and residents of northeast Fukushima may be undergoing mental health crisis. In fact, disaster-related psychological stress could have induced several physical and mental disorders. The mid- and long-term supports are urgently needed not only for psychiatric patients but also for all residents in the district of Soso.

Cronkhite-Canada syndrome associated with myelodysplastic syndrome.

We report a case of Cronkhite-Canada syndrome (CCS) associated with myelodysplastic syndrome (MDS). A 54-year-old woman, diagnosed as MDS the prior year after evaluation of anemia, visited our hospital with the chief complaint of epigastric discomfort. She also had dysgeusia, alopecia, atrophic nail change, and pigmentation of the palm, all of which began several months ago. Blood tests revealed severe hypoalbuminemia. Colonoscopy (CS) showed numerous, dense, red polyps throughout the colon and rectum. Biopsy specimens showed stromal edema, infiltration of lymphocytes, and cystic dilatation of the crypt. Her clinical manifestations and histology were consistent with CCS. We prescribed corticosteroids, which dramatically improved her physical findings, laboratory data, and endoscopic findings. This is the first report of CCS in a patient with MDS.

Autoimmune hepatitis overlapping with primary sclerosing cholangitis.

A case of autoimmune hepatitis (AIH) complicated by primary sclerosing cholangitis (PSC) in a 36-year-old woman is reported. AIH overlapping with PSC has been rarely reported, and to the best of our knowledge, there have been no reports in Japan. Based on the criteria for diagnosis of AIH and on typical endoscopic retrograde cholangiograph (ERC) findings, the patient was diagnosed as having AIH overlapping with PSC. Her transaminase levels normalized within 1 month after administration of prednisone, azathioprine and ursodeoxycholic acid, but her cholestatic enzyme level remained elevated. The effect of treatment on the cholestatic features is thought to be an important factor for predicting the prognosis of AIH overlapping with PSC.
