A 65-year old man with adenocarcinoma in the third duodenal portion was successfully treated with a segmental resection of the third part of the duodenum, avoiding a duodeno-cephalo-pancreatectomy. This tumor is very rare and frequently affects the III and IV duodenal portion. A precocious diagnosis and the exact localization of this neoplasia are crucial factors in order to decide the surgical strategy. Given a non-specificity of symptoms, endoscopy with biopsy is the diagnostic gold standard. Duodeno-cephalo-pancreatectomy (DCP) and segmental resection of the duodenum (SRD) are the two surgical options, with overlapping morbidity (27% vs 18%) and post operative mortality (3% vs 1%). The average incidence of postoperative long-term survival is 100%, 73.3% and 31.6% of cases after 1, 3 and 5 years from surgery, respectively. Long-term survival is made worse by two factors: the presence of metastatic lymph nodes and tumor localization in the proximal duodenum. The two surgical options are radical: DCP should be used only for proximal localizations while SRD should be chosen for distal localizations.展开更多

As such, major hepatectomy requires a careful approach. We describe the usefulness of the Glissonean approach in two patients with vessel anomalies, such as RUP. The first patient underwent a right anterior sectionectomy for intrahepatic cholangiocarcinoma. We encircled several Glissonean pedicles that entered the right anterior section along the right side of the RUP. We temporarily clamped each pedicle, confirmed the demarcation area, and finally cut them. The operation was performed safely and was successful. The second patient underwent a left trisectionectomy for perihilar cholangiocarcinoma. We secured the right posterior Glissonean pedicle. The vessels in the pedicle were preserved, and the other vessels and contents were resected. Identifying the vessels for preservation facilitated the safe lymphadenectomy and dissection of the vessels to be resected. We successfully performed the operation.展开更多

And those which emerge at the anterior cervical portion and infiltrate deep into the neck are even more rare. Generally, this disorder is uncommon existed near the thyroid gland. We report here a case of NML mimicking a thyroid tumor and infiltrating into the deep part of the anterior neck. Case: A mass at the anterior portion of her neck was found at 5 years old. It was not mobile and palpated as an irregularly surfaced hard mass whose size was 3 cm at the anterior lower portion of her neck. Ultrasonography showed an oval mass which existed near the slightly inferior part of the right lobe of the thyroid gland. Enhanced computed tomography showed a mass near the slightly inferior part of the right lobe of the thyroid gland. The mass was resected with the platysma and the right sternohyoid muscle. In the HE staining, epithelioid cell and Langhans type giant cells surrounding coagulative necrosis lesions which seemed to be caseation necrosis existed, similarly to cervical NML. Discussion: No consensus exists for the treatment of NML, but many documents advise complete excision. When the lesion cannot be completely removed, excision as far as possible and additional antibiotics are recommended. The characteristics of imaging of NML around the thyroid gland and infiltrating deep into the anterior neck and mediastinum are discussed.展开更多

Wistar male rats of 5, 15, and 25 days of age were isolated from the mother for 12 h, then stimulated via the intraoral route with quinine, sucrose, or NaCl, and sacrificed 90 min later. The water-stimulated group showed minimal c-fos-like immunoreactivity (FLI) compared with taste-stimulated groups that exhibited different FLI in the rNST at the different ages. At all ages the quinine-stimulated group induced FLI in the medial subfield, while sucrose induced FLI in the lateral subfield of the rNST. The intensity of FLI was highest at P15, and it declined at P25. These findings provide detailed insight into the anatomical basis of rNST activation that is involved in early food intake and the learning capacity of the newborn.展开更多

A total of 251 middle school adolescents participated in this study. Participants’ knowledge was assessed based on their estimation of the energy content of the standard portion size of foods. To estimate the energy intake of the subjects, 24-hr recall was used. The percentage of participants who accurately estimated (that is within 20% of the true value) the energy content of the standard portion size was calculated for each of the 32 typical foods. The food for which the most participants revealed the accurate estimation was cooked rice (39.5%). The proportion of students who overestimated the energy contents was highest for vegetables (98%), and oils and sugar (90%). The female students were more likely than males to provide the accurate estimation of energy contents for standard portion size of foods. After adjusting for age and sex, the estimation level ([estimation value/true value] × 100) of the energy content of some foods had a significant positive relationship with BMI, but had no significant relationship with reported energy intake. From these results, we concluded that the knowledge of energy content of food was poor among middle-school adolescents, with some gender difference, and that their estimation of the calorie contents of foods increased along with their BMI.展开更多
