RESUMEN
The patient was a 72-year-old female. She had been taking rivaroxaban for chronic atrial fibrillation; however, she stopped taking it due to anemia and was hospitalized urgently. A contrast-enhanced computed tomography(CT)scan showed a 30 mm mass in the ascending colon, and a colonoscopy revealed ascending colon cancer(cT3, cN0, cM0, cStage â ¡a). The tumor was hemorrhagic and was thought to have caused the anemia. On day 6 of hospitalization, another contrast- enhanced CT scan showed a poorly contrast-enhanced area in the left atrium, and transesophageal echocardiography revealed 2 left atrial thrombi(27 mm and 17 mm). Since early induction of anticoagulation therapy was considered, an emergency open right colectomy was performed to remove the cause of the bleeding. Intravenous heparin therapy was started the day after surgery and was switched to oral apixaban therapy on the fourth postoperative day. The postoperative course was good, and she was discharged home on the 17th postoperative day. This patient had conflicting clinical problems simultaneously; however, immediate decision-making and initiation of treatment were effective.

We report a case of locally advanced rectal cancer presenting with perforation that was successfully resected after preoperative chemotherapy. A 66-year-old woman visited our emergency room complaining of lower abdominal pain. Abdominal CT showed a rectal tumor with fluid collection and free air in the pelvis. The patient was diagnosed with panperitonitis secondary to cancerous perforation and underwent sigmoid colostomy. A biopsy specimen of the rectal tumor showed well-differentiated tubular adenocarcinoma and wild-type RAS. After 8 courses of mFOLFOX6 plus panitumumab, the tumor shrank remarkably, and radical surgery(low anterior resection with D3 lymph node dissection)was performed. Microscopic examination of the resected specimen showed that almost half of the tumor cells were replaced by histiocytes and necrotic tissue. Preoperative chemotherapy with panitumumab may be an effective treatment for RAS wild-type locally advanced colon cancer, even if the primary tumor develops perforation.

We report a case of nephrotic syndrome induced by ramucirumab for metastatic rectal cancer. A 48-year old woman who had received FOLFIRI plus ramucirumab for rectal cancer with liver, lung, and bone metastases presented to our hospital with edema and increased body weight. Laboratory studies showed hypoalbuminemia and severe proteinuria, and the patient was diagnosed with nephrotic syndrome. After administration of an angiotensin II receptor blocker and thiazide diuretic, her symptoms disappeared and serum albumin level normalized. To the best of our knowledge, this is the first detailed report of nephrotic syndrome related to ramucirumab. This case serves to emphasize that the possibility of nephrotic syndrome should be considered during anti-vascular endothelial growth factor therapy.

BACKGROUND: Rectovaginal fistula (RVF) is a troublesome and refractory complication after low anterior resection (LAR) for rectal cancer. An omental flap repair was performed for the RVF caused due to Crohn's disease and childbirth trauma. However, there are few cases of an omental flap repair for RVF after LAR. Herein, we present a successfully repaired case of RVF by omental flap coverage after LAR for rectal cancer. CASE PRESENTATION: A 50-year-old female patient with advanced rectal cancer underwent laparoscopic LAR with double-stapling technique anastomosis and achieved curative resection. She complained of a stool from the vagina and was diagnosed with RVF on the postoperative day (POD) 18. Conservative therapy was ineffective. We performed laparoscopic fistula resection and direct closure of the vagina and rectum, designed the omentum that could reach the pelvis, repaired RVF by omental flap coverage, and performed transverse colostomy on POD 25. She was discharged on initial POD 48. Seven months after the initial operation, colostomy closure was administered. There was no recurrence of RVF found 1 year after the initial operation. CONCLUSIONS: The patient achieved an omental flap coverage for RVF. We successfully performed the omental flap coverage repair in patients with RVF after the leakage of LAR. An omental flap may become an alternative treatment for muscle flap or an effective treatment for RVF.
RESUMEN
A 5 3-year-old woman was admitted to our hospital because of vomiting. CT scan and gastroduodenoscopy showed severe stenosis of the duodenal 3rd portion. There was no evidence of malignancy. We diagnosed a stricture due to a duodenal ulcer and laparotomy was performed. By means of biopsy of No.14d lymph node in the operation, adenocarcinoma of the duodenum was pointed out and we performed a pancreatoduodenectomy. Although adjuvant chemotherapy with S-1/paclitaxel (S-1 80 mg/body, po, day 1-14 and paclitaxel 120 mg/body iv day 1, 8)was administered after operation, the patient's serum CEA was elevated and metastic lymph nodes around the supra mesenteric artery were pointed out. The patient was started on combined chemotherapy with S-1/CPT-11(S-1 80 mg/body, po, day 1-14 and CPT-11 120 mg/body iv day 1), serum CEA levels returned to normal range, and marked reduction of lymph node size was observed on CT. The patient is still alive and free of disease three years after the operation. S-1/CPT-11 could therefore be a treatment option for patients with duodenal carcinoma.

A 73-year-old man was referred to our hospital with sigmoid colon cancer in July 2009. CT and MRI showed synchronous multiple liver metastasis. After a sigmoid colon resection in August, he received convergent chemotherapy in combination with 5-fluorouracil(5-FU)/Leucovorin(LV)(RPMI regimen)and bevacizumab for liver metastasis. After two courses without any major adverse effects, liver metastasis remarkably reduced on CT and MRI examination. We thus performed a liver resection, and pathological examination revealed a complete response in liver. Combination chemotherapy of 5-FU/LV and bevacizumab can be expected to provide safe and effective treatment for liver metastasis of colon cancer.

A 62-year-old man had undergone anterior resection of rectum for rectosigmoid colon cancer with liver metastases. Postoperatively, the FOLOFOX6 regimen was performed in three courses. Metastatic liver tumors showed progressive disease(PD) on CT scan. The treatment was then changed to the FOLFIRI regimen for three courses. Metastatic liver tumors showed a partial response(PR)on CT scan. After six courses of the FOLFIRI regimen, the patient was given seven courses of the FOLFIRI +BV regimen. Hepatic resection of S2, S3, S4 and S6 segment was performed. The histological effect of chemotherapy was complete response(CR).

Selective REM sleep deprivation was carried out under the conditions designed to minimize the adverse influence of environmental conditions and restricted movement, and the influence of REM sleep deprivation on adrenocortical steroid metabolism was investigated by measuring the steady-state levels of mRNAs encoding steroid metabolism-related genes, steroidogenic acute regulatory protein (StAR), cholesterol side-chain cleavage enzyme cytochrome P450 (P450scc) and steroid 5alpha-reductase (5alpha-R), in rat adrenal glands. Selective REM sleep deprivation caused a significant decrease in StAR mRNA and an increase in 5alpha-R mRNA levels without any notable change in P450scc mRNA levels in the adrenal gland. In contrast, non-selective sleep disturbance, resulting in the partial reductions of non-REM and REM sleep, tended to increase both StAR and P450scc mRNA levels without any statistical significance. These results indicate that REM sleep deprivation by itself may affect the expression of steroid metabolism-related genes in the adrenal gland, suggesting a possible relation between REM sleep and adrenocortical steroid metabolism.
