We report a case of a 72-year-old woman with a tumor arising from a colostomy site that had been created 25 years earlier when rectal amputation was performed for perforated sigmoid cancer. She was referred to our hospital due to complaints of pain from the colostomy. The diagnosis was carcinoma arising at the colostomy site with lymph node metastasis. Laparoscopic surgery was performed by attaching an Applied Alexis® wound retractor to the incision site of the colostomy. Lymph node dissection was performed and the left hemicolon was resected. Carcinoma arising from a colostomy site is rare. Laparoscopic surgery was considered to be a useful procedure because it allows for lymph node dissection and intestinal mobilization with minimal invasiveness.

A chest X-ray taken during a medical checkup for a 75-year-old man revealed a nodular shadow in the right middle lung field. Chest computed tomography (CT) for further examination showed an intra-abdominal tumor as an additional finding, and the patient was referred to our department. Contrast-enhanced CT revealed a tumor (16×10×5 cm) in the left upper to middle abdomen. The tumor had a clear border and uniform fat density inside. It compressed the stomach to the ventral side, but the patient had no subjective symptoms. Magnetic resonance imaging also showed the tumor contained a uniform fatty component inside, as well as no obvious non-fatty components. An intra-abdominal lipoma was suspected, but the possibility of a welldifferentiated liposarcoma could not be ruled out due to its size. During curative surgery, intraoperative findings revealed a soft tumor, weighing 612 g, with a well-defined border in the mesentery of the transverse colon. Pathological findings showed proliferation of mature adipocytes without malignancy. We report here this case of mesenteric lipoma, a rare intraabdominal tumor, and review the relevant literature.

A 57-year-old man was admitted to our hospital with adhesive bowel obstruction following pancreaticoduodenectomy performed for cholangiocarcinoma 4 months earlier. After admission, the patient remained nil per os and was closely observed. On the third day of admission, he developed worsening abdominal pain, and computed tomography revealed strangulation of the small intestinal mesentery dorsal to the superior mesenteric artery, with prolapse of the small intestine into the right upper quadrant to form a closed loop. Strangulated bowel obstruction secondary to internal hernia was diagnosed, and he underwent emergency surgery. Intraoperatively, we detected a hernia orifice formed by the mesentery and peritoneum at the site of the defect following resection of the ligament of Treitz, and we observed that approximately 2 m of the small intestine had prolapsed into the right upper quadrant. The herniated intestine was returned to the abdominal cavity, and the hernia orifice was sutured following hernia reduction. Few reports have described an internal hernia after pancreaticoduodenectomy; however, it has been reported that this operation can result in various types of internal hernia because of the complicated reconstructive procedure. Here we report our findings in this unique case together with a literature review.

BACKGROUND/AIMS: Oral mesalazine is an important treatment for ulcerative colitis (UC), and non-adherence to mesalazine increases the risk of relapse. Controlled-release (CR) mesalazine has 2 formulations: tablets and granules. The relative acceptabilities of these formulations may influence patient adherence; however, they have not been compared to date. This study aimed to evaluate the acceptabilities of the 2 formulations of CR mesalazine in relation to patient adherence using a crossover questionnaire survey. METHODS: UC patients were randomly assigned to 2 groups in a 1:1 ratio. Patients in each group took either 4 g of CR mesalazine tablets or granules for 6 to 9 weeks, and then switched to 4 g of the other formulation for a further 6 to 9 weeks. The acceptability and efficacy were evaluated by questionnaires, and adherence was assessed using a visual analog scale. The difference in acceptabilities between the 2 formulations and its impact on adherence were assessed. RESULTS: A total of 49 patients were prospectively enrolled and 33 patients were included in the analysis. Significantly more patients found the tablets to be less acceptable than the granules (76% vs. 33%, P=0.0005). The granules were preferable to the tablets when the 2 formulations were compared directly (73% vs. 21%, P=0.004), for their portability, size, and numbers of pills. The adherence rate was slightly better among patients taking the granules (94% vs. 91%) during the observation period, but the difference was not significant (P=0.139). CONCLUSIONS: CR mesalazine granules are more acceptable than tablets, and may therefore be a better option for long-term medication.

BACKGROUND/AIMS: The pharmacokinetics of tacrolimus (TAC) is known to be largely influenced by single-nucleotide polymorphisms (SNPs) in CYP3A5. Patients starting TAC require careful dose adjustment, owing to the wide range of optimal dosages, depending on their CYP3A5 expression status. Here, we evaluated whether individualization of TAC dosages based on CYP3A5 SNPs would improve its therapeutic efficacy in ulcerative colitis. METHODS: Twenty-one patients were prospectively treated, with their initial dosage adjusted according to their CYP3A5 status (0.1, 0.15, and 0.2 mg/kg/day for CYP3A5*3/*3, CYP3A5*1/*3, and CYP3A5*1/*1, respectively). Their clinical outcomes were compared with those of patients treated with a fixed dose (0.1 mg/kg/day). RESULTS: The first blood trough level of CYP3A5 expressors, CYP3A5*1/*3 or CYP3A5*1/*1, and the overall rate in achieving the target blood trough level within a week in the individualized-dose group were significantly higher than those in the fixed-dose group (5.15±2.33 ng/mL vs. 9.63±0.79 ng/mL, P=0.035 and 12.5% vs. 66.7%, P=0.01). The remission rate at 2 weeks in the expressors was as high as that in the nonexpressors, CYP3A5*3/*3, in the individualized-dose group. CONCLUSIONS: Individualized TAC treatment is effective against ulcerative colitis regardless of the CYP3A5 genotype.

Drug dispensing is a statutory and designated duty of a pharmacist. We aimed to examine the changes in the nature of drug dispensing using a text mining method. Our corpus consisted of text documents from “Chozai Shishin”, the most standard manual for dispensing drugs in Japan, Editions 1 to 13 (Japan Pharmaceutical Association), and we used the KH Coder software for text mining. We constructed networks showing the association between frequent word co-occurrence and edition number, and co-occurrence relations for frequent words in each edition. We found that “patient” superseded “dispensing” as a frequent term over time. “Dispensing” was another frequent term with a highly centralized node in each edition. Accordingly, we targeted the term “dispensing” for network analysis to depict its co-occurrence relations. We found that the range of related words for “dispensing” broadened from “preparation” and “compounding” to include “patient adherence instructions”, “assessment”, “medical treatment”, and “information provision”. Accordingly, we concluded that the content of “dispensing”, which is a pharmacist’s duty, has expanded from the duties of “dispensing drugs” to include “responding to patients” within the definition of “dispensing”, and we were able to present this finding as objective data by using the mechanical method known as text mining.

Bovine abortion, diarrhea, and respiratory disease complexes, caused by infectious agents, result in high and significant economic losses for the cattle industry. These pathogens are likely transmitted by various vectors and reservoirs including insects, birds, and rodents. However, experimental data supporting this possibility are scarce. We collected 117 samples and screened them for 44 bovine abortive, diarrheal, and respiratory disease complex pathogens by using Dembo polymerase chain reaction (PCR), which is based on TaqMan real-time PCR. Fifty-seven samples were positive for at least one pathogen, including bovine viral diarrhea virus, bovine enterovirus, Salmonella enterica ser. Dublin, Salmonella enterica ser. Typhimurium, and Neospora caninum; some samples were positive for multiple pathogens. Bovine viral diarrhea virus and bovine enterovirus were the most frequently detected pathogens, especially in flies, suggesting an important role of flies in the transmission of these viruses. Additionally, we detected the N. caninum genome from a cockroach sample for the first time. Our data suggest that insects (particularly flies), birds, and rodents are potential vectors and reservoirs of abortion, diarrhea, and respiratory infectious agents, and that they may transmit more than one pathogen at the same time.

Introduction : We examined the characteristics of paralytic scoliosis using plain radiography.Subjects and methods : We recruited fourteen patients aged ≥ 15 years old with no history of bone surgery at the time of their final observation. Participants included those who had cerebral palsy or those who had a history of encephalitis and underwent spinal frontal plain radiography in the supine position at different time points. We evaluated gross motor function, position and direction of the curve, Cobb angle, rate of variability, and degree of progression at 5-year intervals. We measured the percentage of migration using hip frontal plain radiography to assess hip dislocation.Results : The final Cobb angles were 82.0°, 118.4°, and 92.3°for the thoracic, thoracolumbar (TL), and lumbar curvatures, respectively. TL curvatures showed the greatest progression, although this was not statistically significant. The progression was greatest in the 10-15-year age group (12.5°annually). The final Cobb angles in the hip dislocation, subluxation, and no dislocation groups were 102.8°, 108.8°, and 87.5°, respectively；the difference was not statistically significant. No relationship was observed between the location or progression of curvature and the state of the hip location.Discussion : Paralytic scoliosis progressed most rapidly in 10-15-year-old patients, especially in those with TL lesions. We did not detect any relationships between hip dislocation and Cobb angle, but these parameters progressed at different rates in different patients.
