Abstract

Importance: Self-feeding independence is often the first goal in acute stroke rehabilitation. Attention deficits appear frequently after stroke, but neuropsychological tests may be difficult to perform in the acute phase, and the effect on self-feeding activities may be difficult to detect. Therefore, we aimed to clarify behavioral problems with self-feeding using the Moss Attention Rating Scale (MARS), a behavioral observational rating scale of attentional function, for a better understanding of the effects of self-feeding. Objective: To identify behavioral problems caused by attention deficits among patients with acute stroke who need assistance in self-feeding, using the MARS. Design: Cross-sectional single-center study. Setting: St. Marianna University Yokohama Seibu Hospital, Kanagawa, Japan. Participants: A total of 96 patients (42 women and 54 men) were admitted to the hospital for stroke treatment. Patients' median age was 75.0 yr. The date of evaluation was a median of 3.0 days from admission. Outcome and Measures: The primary outcome was the FIM® eating subscore. The secondary outcome was the MARS score. Results: Significant differences were noted in the total raw MARS, logit, and three-factor scores for self-feeding independence (p <.01). The effect size of the consistent or sustained factor on independence was large (r =.83). Conclusions and Relevance: Behavioral problems related to self-feeding dependence include the inability for sustained attention. Our results suggest that sustained concentration during self-feeding is necessary for eating independence. Rehabilitation focused on sustained attention is important for independent self-feeding. Plain-Language Summary: A patient's self-feeding independence is often the first goal in acute stroke rehabilitation. Patients frequently experience attention deficits after a stroke, but neuropsychological tests may be difficult to perform in the acute phase of rehabilitation, and the effect of attention deficits on self-feeding may be difficult to identify. To have a better understanding of the effects on self-feeding, this study aimed to identify behavioral problems using the Moss Attention Rating Scale (MARS). The study found that the MARS can be used to identify behavioral problems related to self-feeding independence, which can help occupational therapists to develop rehabilitation programs for their clients who have experienced a stroke. The Moss Attention Rating Scale can be used to identify behavioral problems related to self-feeding independence, which can help occupational therapists to develop rehabilitation programs for their clients who have experienced a stroke.

Abstract

Abstract Background Th1/Th2 cell balance is thought to be shifted toward a Th2-type immune response not only by malignancy but also by surgical stress. The aim of this study was to estimate perioperative immune responses with respect to the Th1/Th2 balance in patients with gastrointestinal cancer. Methods Ninety-four patients who underwent abdominal surgeries were divided into three groups: gastric resection (n = 40), colorectal resection (n = 34) and hepatic resection (n = 20). Twelve patients undergoing laparoscopic cholecystectomy and 20 healthy subjects were served as control groups. Intracellular cytokine staining in CD4+ T lymphocytes was identified to characterize Th1/Th2 balance. Th1/Th2 balance was evaluated before operation and until postoperative days (POD) 14. Results The preoperative Th1/Th2 ratio was significantly lower in patients with malignancy compared with control. The Th1/Th2 ratio of patients in all groups decreased significantly postoperatively. Th1/Th2 balance on POD 2 in patients with malignancy was significantly decreased compared to patients with laparoscopic cholecystectomy, but there were no significant differences among the four groups on POD 14. Conclusion Patients with malignancy showed an abnormal perioperative Th1/Th2 balance suggesting predominance of a type-2 immune response. Major abdominal surgeries induce a marked shift in Th1/Th2 balance toward Th2 in the early postoperative stage.

Abstract

Abstract Bckground A number of studies have investigated whether the activity levels of enzymes involved in 5-fluorouracil (5-FU) metabolism are prognostic factors for survival in patients with colorectal carcinoma. Most reports have examined thymidylate synthetase (TS) and dihydropyrimidine dehydrogenase (DPD) in unresectable or metastatic cases, therefore it is unclear whether the activity of these enzymes is of prognostic value in colorectal cancer patients treated with radical resection and adjuvant chemotherapy with 5-FU. Methods This study examined fresh frozen specimens of colorectal carcinoma from 40 patients who had undergone curative operation and were orally administered adjuvant tegafur/uracil (UFT) chemotherapy. TS, DPD and orotate phosphoribosyl transferase (OPRT) activities were assayed in cancer tissue and adjacent normal tissue and their association with clinicopathological variables was investigated. In addition, the relationships between TS, DPD and OPRT activities and patient survival were examined to determine whether any of these enzymes could be useful prognostic factors. Results While there was no clear relationship between pathological findings and TS or DPD activity, OPRT activity was significantly lower in tumors with lymph node metastasis than in tumors lacking lymph node metastasis. Postoperative survival was significantly better in the groups with low TS activity and/or high OPRT activity. Conclusion TS and OPRT activity levels in tumor tissue may be important prognostic factors for survival in Dukes' B and C colorectal carcinoma with radical resection and adjuvant chemotherapy with UFT.

Abstract

A 70-year-old woman was admitted to our hospital with a complaint of bulging in the right lower portion of the abdomen. The bulging was in accordance with an old operative scar for appendicitis. The findings of computed tomography (CT) showed defects in the abdominal muscles and the protrusion of the intestine into the subcutaneous fat. The patient was diagnosed with incisional hernia after appendectomy and underwent are pair of the incisional hernia, using the prolene hernia system double-layer mesh. The patient’s post-operative course was excellent. Recently, the prolene hernia system, double-layer mesh was reported to be effective for groin hernias due to its advantageous protection the recurrence through reinforcement of the patient’s myopectrial orifice. It is suggested that this new device is also useful for small incisional hernias.

Abstract

We previously reported that the combined treatment of perioperative administration of donor splenocytes via the recipient's portal vein (DSPV) and a short-course Tacrolimus significantly prolonged the survival of fully allogenic grafts in rat small bowel transplantation (SBTX). In the present study we examined whether this effect depended on the quantity of the administered alloantigens in DSPV. In addition, we examined the expression of the surface antigen on T cells of the splenocytes and the induced toleragenic factor, according to the tolerant recipients which in our previous report had shown the prolongation of allogenic transplant small bowel graft survival by the combined treatment of DSPV (1×108 donor splenocytes) and a short-course Tacrolimus. Donor splenocytes were prepared from Brown-Norway (BN (RT1n)) rat spleens for Lewis (LEW (RT1l)) recipients. The recipients (n=10), treated with a short course of Tacrolimus (0.5mg/kg, 0 to 3 days postoperatively) only showed graft rejection with an average of 6.3±1.0 days postoperatively. However, the combined treatment, consisting of DSPV of 1×108 donor splenocytes and a short course Tacrolimus significantly prolonged graft survival to 12.7±2.1 days (n=12, P

Abstract

Rectal sheath hematoma has been a well-known clinical entity from the ruin of the ancient Greece. It is relatively rare, however, to encounter this abdominal disorder in the clinical setting. Furthermore, the initial symptoms of rectus sheath hematoma are often similar to those of acute abdominal disorders. Therefore, the majority of the patients with rectus sheath hematoma have been treated with operative procedures because of the difficulty of a differential diagnosis from other abdominal disorders. We recently treated a 74-year female diagnosed with rectus sheath hematoma with the anticoagulants after an episode of cerebral infarction. From the findings of the physical examinations, ultrasound, and computed tomography, we could correctly diagnose, and could treat her with completely conservative methods without any invasive techniques. It is stressed that it is important to recognize this entity of rectus sheath hematoma when patients are examineed, after complaining of acute abdominal pain and with evidence abdominal masses in the clinical setting.

Abstract

Early diagnosis of strangulation obstruction is very important for surgeons because delayed diagnosis often leads to severe complications. Thirty patients underwent an operation because of small bowel obstruction between April, 1993 and December, 1999. In the present study, we examined the differences in clinical findings between simple obstruction and strangulation obstruction. In addition, we examined the manifestation of systemic inflammatory response syndrome (SIRS) and whether it is useful for early diagnosis of strangulation obstruction, and whether it is correlated with the severity of ischemia due to strangulation. Tenderness was examined in all patients and signs such as abdominal irritation were detected more often in patients with strangulation obstruction than in the patients with simple obstruction. According to SIRS, the large number of the patients with strangulation obstruction showed SIRS before operation and the manifestation of SIRS correlated well with the length of the necrosis in the strangulated small bowel. We recognized the importance of anamnesis and clinical findings in examinations of small bowel obstruction, furthermore, it was suggested that SIRS should be the warning sign for strangulation obstruction.

Abstract

The double layer capacitance of an activated carbon nanofiber (ACNF) with a 100∼200 nm fiber-diameter, prepared by the polymer blend spinning technique, was investigated using 1-ethyl-3-methylimidazolium tetrafluoroborate (EMImBF₄) as the electrolyte. The conventional activated carbon fiber (ACF) with the fiber-diameter of ∼10 µm and narrow micropores (∼0.7 nm pore-width) showed a significant irreversible adsorption of EMIm⁺ cation in EMImBF₄, however, the ACNF effectively suppress the irreversibility even with the pore structure comparable to the conventional ACF. This suggests the effect of the short pass length on the ion adsorbing/desorbing process. The decreased capacitance by the cycling in EMImBF₄ was recovered by the addition of propylene carbonate as an organic solvent to the electrolyte. This means that the irreversible adsorbed ions can be desorbed using propylene carbonate.

Abstract

An 85-year-old woman was admitted to our hospital because of vomiting. An upper gastrointestinal series what showed a large esophageal hiatus hernia, suggesting an association with extrinsic pressure in the middle portion of the stomach. An upper gastrointestinal endoscopic examination showed severe esophagitis and a prominent narrowing in the middle portion of the stomach, however, it showed normal gastric mucosa findings. CT and MRI revealed a large tumor extending from the region of the lower chest to the upper abdomen. From these findings, the tumor was diagnosed as gastrointestinal stromal tumor(GIST), which arose from the gastric wall and complicated with an esophageal hiatus hernia. We performed a laparotomy, however, the tumor showed severe invasion to the circumferential organs. Therefore, we abandoned the excision of the tumor. Histologically, the tumor was composed of spindle shaped cells with marked nuclear atypia and prominent mitosis. The tumor cells were strongly positive for CD34 and c-kit by immunohistochemical examination. From these findings, the tumor was definitely diagnosed as a malignant GIST. As palliative treatment, we implanted a self-expandable metallic stent in the narrow segment of the stomach. The patient could eat solid food and was discharged. In the treatment of esophageal hiatus hernia, the rare association of GIST should be considered.
