RESUMO
A 72-year-old woman underwent a low anterior resection of the rectum and a total hysterectomy with a bilateral salpingo- oophorectomy simultaneously for rectal and ovarian cancer, respectively. The pathological diagnosis was a moderately differentiated adenocarcinoma of the rectum with some poorly differentiated components signet-ring cell components. A mucinous adenocarcinoma, with similar characteristics as that in the rectum, was found in the ovary. Intraoperative findings revealed no direct invasion between the rectum and ovaries, with no peritoneal dissemination. She was, therefore, diagnosed with synchronous double cancer. The rectal cancer was pT3N0M0, Stage â ¡ and the ovarian cancer pStage â . Adjuvant chemotherapy with capecitabine was performed for high-risk Stage â ¡ rectal cancer. At 3.5 years after surgery, her CA19-9 level was high and pleural dissemination and para-aortic lymph node metastasis were confirmed on thoracoabdominal CT. Twelve years after the gastrectomy for gastric cancer, a comparison of the pathological specimens of her stomach at that time with the current pathological specimens revealed that the rectal and ovarian tumors were metastases of gastric cancer and that the current recurrence was a late recurrence of this disease. Late recurrence after gastrectomy, especially 10 years or more after surgery, is extremely rare.

Although gingivitis frequently occurs in young cats, spirochetes are often found in the early stages of periodontal disease. This study was conducted to determine the association between gingivitis and oral spirochetes in young cats and dogs. The degree of gingivitis was evaluated in a total of 68 cats and 31 dogs under one year of age, and plaques were collected from each carnassial. To detect spirochetes or Porphyromonas gulae in plaque samples, 16S rRNA gene was amplified by polymerase chain reaction (PCR) using specific primers. All data were analyzed using Fisher's exact probability test and odds ratio (OR) with a 95% confidence interval (95% CI). The prevalence of gingivitis was significantly higher in young cats (92.6%) than in young dogs (45.2%). The positive rate of spirochetes by PCR in gingivitis cases was 85.4% in young cats and 15.4% in young dogs, and the positive rate of P. gulae was 66.7% in young cats and 15.4% in young dogs. Both results were significantly higher in young cats than in young dogs. In young cats, spirochetes were significantly associated with gingivitis (OR = 7.95; 95% CI = 1.17, 53.83; P < 0.05), but P. gulae was not (OR = 2.44; 95% CI = 0.38, 15.66; P = 0.23). These results suggest that spirochetes may be associated with the early stages of periodontal disease in cats.

Immunotherapy-based combinations have played a central role in the treatment of metastatic renal cell carcinoma, and long-term survival of patients is expected. In this context, it is clear that a certain number of patients can achieve a complete response. However, the diagnosis of complete response is usually based on imaging, and there are few cases of pathological complete response. In this study, we report a case of a patient with metastatic renal cell carcinoma who was treated with pembrolizumab plus axitinib, followed by resection of the primary tumor and metastatic lesions, and pathologically achieved a complete response.
RESUMO
BACKGROUND: Although distant metastasis from pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis, some single center studies reported that lung metastasis has a favorable prognosis. The aim of this study is to evaluate the prognostic value of site-specific metastasis after pancreatectomy for PDAC, with a focus on lung metastasis. METHODS: Data from 117 cases of lung metastasis after pancreatectomy were collected retrospectively from 23 institutions in Japan. To compare the sites of metastasis we also collected the data of 134 patients with liver only metastasis, 67 patients with peritoneal only metastasis and 121 patients with locoregional recurrence alone. RESULTS: In patients with lung only metastasis, the median time from recurrence to death (RTD) was 23.1 months, which was better in comparison to other sites of recurrence. In lung metastasis group, the patients who underwent pulmonary resection had better long-term outcomes in comparison to those who did not. (RTD: 29.2 vs 15.2, P < .001). In the multivariate analysis, solitary metastasis (HR 5.03; 95% CI 1.195-21.144, P = .022) and postoperative chemotherapy (HR 14.089; 95% CI 1.729-114.77, P = .023) were identified as significant prognostic factors after lung resection. CONCLUSIONS: Surgical resection is a favorable option for selected patients with a solitary lung metastasis and for whom adjuvant chemotherapy can be administrated.

Intraoral administration of canine interferon alpha (CaIFN-α) has been shown to reduce gingivitis in dogs, but has not been confirmed in cats. Therefore, in this study, a CaIFN-α preparation was used for feline gingivitis, and the degree and duration of its effects were examined. Cats were divided into two groups: one was administered CaIFN-α, and the other was not. They were observed up to 12 months. It was suggested that CaIFN-α have a reducing effect on gingivitis and halitosis for a certain period although may not on plaque or calculus. In addition, the duration of the CaIFN-α gingivitis-reducing effect was suggested to be about three months. The CaIFN-α preparation is considered to be a useful treatment for oral hygiene control.

INTRODUCTION: Almost all patients with end-of-life cancer experience cancer-related fatigue; however, there are only a few known effective coping methods. OBJECTIVES: We will conduct a prospective, multi-center, single-blinded randomized controlled study to evaluate the efficacy of acupuncture for cancer-related fatigue in patients with end-of-life cancer. METHODS: We will enroll 120 patients with cancer hospitalized in a palliative care unit or receiving consultation from a palliative care team in four hospitals. We will add acupuncture treatment; specifically, contact needle therapy (CNT), consisting of an intervention per week period to the usual care. The primary outcome measure will be the Cancer Fatigue Scale (CFS) score while the secondary outcome measures will be the Numerical Rating Scale (NRS) score for fatigue, pain, and salivary amylase levels. CONCLUSION: We will evaluate the possibility of using acupuncture therapy, that is, CNT, in relieving fatigue sensation in patients with advanced cancer.

A 50-year-old man presented with epigastric pain after eating raw mackerel. Abdominal computed tomography revealed submucosal edema of the gastric antrum and pelvic ileum. Gastroscopy revealed an Anisakis simplex in the gastric antrum. His epigastric pain resolved after endoscopic removal of the Anisakis; however, he developed right lower quadrant pain the following day. Abdominal computed tomography showed submucosal edema of the terminal ileum involving different ileal loops, which was not present on admission. The patient developed delayed intestinal anisakiasis. A serving of raw fish may contain more than one Anisakis. After gastric anisakiasis, a second Anisakis may cause intestinal anisakiasis.
RESUMO
A 90-year-old female patient was admitted to our hospital with a chief complaint of vomiting.Gastroscopy revealed type 3 gastric cancer and gastric outlet obstruction(GOO).Abdominal computed tomography revealed thickening of the antral wall and suggested the presence of 3 perigastric lymph node metastases, but there was no ascitic fluid or distant metastasis.The clinical diagnosis was T4a(SE)N2H0CYXP0M0, Stage III B, according to the Japanese Classification of Gastric Carcinoma.Her general conditions including kidney and cardiac function were good, we considered that she was able to tolerate radical distal gastrectomy.We planned laparoscopic distal gastrectomy(LDG)and D2 lymphadenectomy after getting sufficient informed consent.The patient experienced an uneventful post-operative recovery, and was discharged in good health 11 days after surgery.

A 69-year-old man with right upper quadrant abdominal pain and fever was referred to our hospital. He had a history of asbestosis exposure. Computed tomography(CT)revealed a mass at the right subhepatic space, and an antibiotic was administered after a diagnosis of an abdominal abscess. However, the patient did not respond to the treatment, and finally, exploratory laparoscopy was performed. A sheet of combined white nodules surrounding the right lobe of the liver was found, and the mass was continuous with the covering particles. Biopsy of the mass and immunohistochemical examination was performed. The resulting diagnosis was diffuse epithelial malignant peritoneal mesothelioma(MPM). Postoperative systematic chemotherapy of pemetrexed and cisplatin was administered. Laparoscopy was useful to evaluate the distribution of the MPM, which led to adequate therapeutic determination.

An 86-year-old man was brought in ambulance to our hospital because of sudden hematochezia and abdominal pain during defecation. Intestinal prolapse approximately 80mm from the anus and a type 1 tumor 50mm in size on the mucosal surface were detected. The intestinal prolapse was manually repositioned, and the reduction of the intussusception was confirmed by computed tomography (CT). Following colonoscopy and abdominal-enhanced CT, a sigmoid colon cancer without distant metastases was detected. Elective laparoscopic radical surgery was performed. The present study described a rare case of sigmoid colon cancer with an intussusception prolapsing through the anus and highlighted the treatment strategy by reviewing 48 previous cases. The treatment strategy employed was as follows:first, manual repositioning of the intestinal prolapse was attempted;and second, the presence of intussusception was confirmed by CT. In cases when repositioning of the intussusception was not possible, even with the use of an endoscope or contrast enema, emergency surgery was required.

A 58-year-old man underwent rectal resection(D2 dissection)for rectal cancer and liver/lung metastases in August 2009. Histopathological findings were Ra, type 2, 70×80mm, tub1>tub2, int, pSI(peritoneum), INF b, ly1, v1, pN1(2/13), pPM0, pDM0, M1a(H1, PUL1), fStage IV . The lung metastasis had disappeared on chest CT after postoperative chemotherapy and we were able to perform radical resection of the liver metastasis by performing hepatectomy twice. In October 2013, anal pain appeared and a painful tumor approximately 2 cm in size was found in the 5 o'clock direction of the anus. Biopsy revealed a well-differentiated tubular adenocarcinoma similar to rectal cancer, and it was diagnosed as a fistula metastasis of rectal cancer.We performed chemoradiotherapy(S-1 120mg/day plus RT 60 Gy/30 Fr)as surgery was recommended but refused. As a result, the tumor reduced markedly in size. In December 2015, the tumor enlarged in size and the patient and family requested surgery. We, therefore, performed abdominoperineal resection. Currently, the patient is alive at 18 months after surgery with no recurrence.

A 73-year-old man was admitted with sigmoid colon diverticulitis. Although a biopsy did not indicate malignancy, the sigmoid colon was completely obstructed following conservative treatment. After sigmoidectomy, the histopathological findings revealed a well-differentiated adenocarcinoma localized to the mucosal surface; invasive micropapillary carcinoma (IMPC)accounting for>95% of the tumor volume spread extensively below the submucosal layer. IMPC is highly malignant and difficult to diagnose preoperatively, possibly due to the presence of poorly differentiated histological sub-types in the deepest portions of the tumor.

A spontaneous external biliary fistula is most commonly a cholecystocutaneous fistula secondary to acute cholecystitis. A fistula arising from an intrahepatic duct is extremely rare. An 87-year-old man presented with swelling of the epigastric region and right upper quadrant abdomen. He had a history of cholecystectomy and endoscopic sphincterotomy. After antibiotic treatment and surgical opening of both lesions, abdominal computed tomography demonstrated a soft tissue mass cephalad to the umbilicus. We excised the mass, and found it to be associated with a fistula through the linea alba. Fistulography showed an abscess cavity communicating with the intrahepatic duct in segment III. Histopathological examination of the mass showed an abscess without malignancy. The fistula closed spontaneously without laparotomy. In this case, the underlying pathology was considered to be associated with a subcapsular hepatic cyst in segment III.

Aim: Bladder ruptures are commonly misdiagnosed as gastrointestinal perforations or intestinal ischemia. If a diagnosis is made preoperatively, conservative treatment is a safe and effective option. We evaluated the validity of using the attenuation value of ascites, measured by non-contrast computed tomography (CT), to identify patients with bladder ruptures. Methods: A retrospective search of our hospital database identified 7 patients with confirmed bladder ruptures between 2007 and 2013. We also enrolled 18 patients with gastrointestinal perforations and 10 patients with intestinal ischemia with detectable ascites on abdominal CT that had undergone emergency exploratory laparotomy between 2007 and 2013. Between-group comparisons of attenuation values of ascites as obtained by non-contrast CT were evaluated. Results: All attenuation values were less than 10 Hounsfield units (HU) in bladder rupture patients. Moreover, the attenuation value of ascites in cases of bladder rupture (median, 5.7; range, 3.1-6.1) was significantly lower than in cases of gastrointestinal perforation (median, 14.7; range, 4.7-25.4) and intestinal ischemia (median, 13.3; range, 6.0-18.1) (P = 0.004 for both comparisons). Conclusion: Bladder rupture mimics gastrointestinal perforation and intestinal ischemia with acute kidney injury. Therefore, the diagnosis of bladder rupture using the attenuation value of ascites on non-contrast CT is both useful and highly significant. We suggest that bladder rupture be considered in the differential diagnosis of patients presenting with acute abdominal pain and attenuation values of ascites of less than 10 Hounsfield units.
RESUMO
Neuroleptic malignant syndrome (NMS) with characteristic symptoms is a potentially lethal reaction to antipsychotic drugs. Atypical NMS usually lacks major symptoms and frequently occurs after treatment using atypical antipsychotics, such as aripiprazole. A 64-year-old man developed aripiprazole-induced NMS after surgery, and our early recognition of the NMS was based on high creatine kinase levels and low serum iron levels. His characteristic symptoms (a fever, rigidity, and altered mental status) were only present for a few hours and were resolved by aripiprazole discontinuation and supportive care. Aripiprazole-induced NMS can present with brief but major symptoms, and clinicians may overlook this "brief" appearance of NMS.

BACKGROUND: No report has described the predictive factor of surgical difficulty for laparoscopic cholecystectomy (LC) by preoperative computed tomography (CT) findings. This study aimed to investigate whether dynamic CT findings can predict the difficulty of LC for acute cholecystitis. MATERIALS AND METHODS: Fifty-seven patients who underwent emergency LC and dynamic CT preoperatively were enrolled. Difficult LC (DLC) was defined as any patient with an operative time ≥3 h, bleeding volume ≥300 mL, common bile duct injury, partial cholecystectomy, the need for a second surgeon, and/or conversion to open surgery. Patients were assigned to either the DLC (+) or DLC (-) group. We determined the CT attenuation ratio of the arterial phase (ARAP) to represent the degree of transient focal enhancement of the liver adjacent to the gallbladder. The ARAP cutoff value for a DLC predictor was determined using receiver operating characteristic curve analysis. Patients' characteristics and CT findings, including the ARAP, were compared between the groups. The Fisher exact test for categorical variables and the Mann-Whitney U test for continuous variables with Bonferroni correction were used to evaluate the significance of differences. RESULTS: Fifteen patients were assigned to the DLC (+) group. The ARAP was significantly higher in the DLC (+) group than in the DLC (-) group (P = 0.006). The ARAP cutoff value was 1.55. Regarding the CT findings, an ARAP ≥1.55 (P = 0.005) was significantly correlated with DLC. CONCLUSIONS: Among dynamic CT findings, an increased ARAP is a predictive factor for DLC.

The patient was a 64-year-old man with esophagogastric junction cancer. We performed right thoracotomy-laparotomy for lower esophageal and cardiac gastric resection, D2 lymphadenectomy, and reconstruction of a gastric tube in October 2011. Histopathology confirmed T4aN1M1(LYM), Stage IV cancer(Japanese Classification of Gastric Carcinoma, 14th edition) with R0 resection. Because of preexisting alcoholic cirrhosis, postoperative chemotherapy was not an option. In March 2014, we performed left adrenalectomy for left adrenal metastasis, and in December 2014, we performed right adrenalectomy for metastasis to the right adrenal gland. The patient was prescribed 20mg/day of hydrocortisone postoperatively. Survival from the right adrenalectomy was 2 years and 2 months, and survival from the first operation was 5 years and 4 months, without recurrence. This case of esophagogastric junction cancer resection with bilateral adrenal metastasis is rare, with only one previously reported case in Japan.

An 80-year-old man who had undergone distal gastrectomy and Billroth-II gastrojejunostomy 38 years previously, for a benign gastric ulcer, was diagnosed with remnant gastric cancer based on upper gastrointestinal endoscopy findings. He presented at our emergency department with acute-onset epigastric pain due to perforated remnant gastric cancer. Conservative medical management was selected, including nasogastric tube insertion, antibiotics, and proton pump inhibitors, because his peritonitis was limited to his epigastrium and his general condition was stable. Twenty-one days after the perforation occurred, curative total remnant gastrectomy and D2 lymphadenectomy were performed. Adhesion between the lateral segment of the liver and the dissected lesser curvature of the gastric remnant may have contributed to the peritonitis in this case, which was limited to the epigastrium. This is the first report of perforated remnant gastric cancer in which conservative treatment was effective prior to curative resection. The protocol reported here may be of use to other clinicians who may encounter this clinical entity in their practices.
