  • Intestinal tuberculosis presents with nonspecific and variable clinical manifestations. It is rarely seen in current clinical practice and the diagnosis may be missed or confused with many other disorders such as Crohns disease and intestinal neoplasms. The route of infection by tuberculous enteritis is variable and the treatment regimens used for treating pulmonary tuberculosis are generally effective for tuberculous enteritis as well. Uncomplicated tuberculous enteritis can be managed with a nine to 12- month course of antituberculous chemotherapy. If not treated early, the prognosis for intestinal tuberculosis is poor, with an overall mortality of between 19 percent and 38 percent. However, 90 percent of patients will respond to medical therapy alone if started early. Therefore, early detection and treatment is essential. Here we report a case of intestinal tuberculosis secondary to miliary tuberculosis.

  • Recently many mutual authentication protocol for light-weight hash-based for RFID have been proposed. Most of them have assumed that communications between a backend server and reader are secure, and not considered threats for backend server and RFID reader impersonation. In the real world, however, attacks against database or reader are more effective rather than attacks against RFID tag, at least from attacker's perspective. In this paper, we assume that all communications are not secure to attackers except the physical attack, and considering realistic threats for designing a mutual authentication protocol based on hash function. And It supports a mutual authentication and can protect against the replay attack, impersonation attack, location tracking attack, and denial of service attack in the related work. We besides provide a secure and efficient RFID mutual authentication protocol which resists impersonation attacks on all of the entities and alow a backend server to search tag-related information efficiently. We conclude with analyzing the safety and efficiency among latest works.

  • An accurate early diagnosis of congenital midgut malrotation is essential to prevention of catastrophic effects of volvulus. To evaluate the usefulness of radiologic examinations in diagnosing intestinal malrotation, we retrospectively analyzed radiologic findings and operation records of 17 intestinal malrotation patients, who were radiologically diagnosed. The age range of the patients studied were from 1day to 12years. The presenting symptoms were vomiting, vomiting with abdominal pain, abdominal distention, diarrhea and failure to thrive. The viewpoints of this analysis were the location of duodeno-jejunal flexure on barium meal and cecal location on barium enema. Sixteen of 17 patients, who were radiologically diagnosed, were surgically proven, but one patient with annular pancreas was false positive. In the case of 3 surgically proved patients, malrotation was suspected on barium meal prior to the barium enema, but final diagnosis was determined on barium enema examination. We concluded that a barium enema should be performed on all children with suspected malrotation where the initial upper gastro-intestinal study was normal or suspicious on account of the small incidence of false positive and false negative barium meals.

  • Although amaranth, a red-colored tar dye, is usually used in foods, cosmetics, and pharmaceutics, its bioavailability and intestinal absorption have not previously been investigated. Therefore, the purpose of this study was to investigate the pharmacokinetics properties and intestinal permeability of amaranth in rats following the intravenous and oral administration of this dye. Amaranth rapidly disappeared from the plasma following the intravenous injection, with a half-life of 38.8 minutes. However, the plasma concentration of amaranth was increased to 400 minutes following the oral administration of amaranth, and the absorption time and bioavailability of amaranth were calculated to be 356 minutes and 55.6%, respectively. This suggests that once amaranth exists in the gut, this dye may be efficiently and effectively absorbed. Consistent with this result, the intestinal permeability of amaranth was comparable to atenolol, a marker compound of moderate permeability, and to one-third of caffeine's intestinal permeability (a highly permeable compound). In conclusion, a significantly long absorption time and substantial intestinal absorption of amaranth was observed following the oral administration of amaranth at a dose of 300 mg/kg in rats, despite the rapid elimination of this dye from the plasma. These results may suggest the necessity of a careful and limited use of amaranth dye when it is added to food, lip-care cosmetics, and orally administered pharmaceutics.

A Case Report of Korean Medical Treatment for an Adult with Cyclic Vomiting Syndrome Analyzed by Electrogastrography and Subjective Evaluation Scale (위전도 검사와 주관적 평가척도를 통해 분석한 성인 주기성 구토 증후군 환자의 한의 치료 증례보고)

  • Objectives: This case study reports the effectiveness of Korean medical treatment in a patient with cyclic vomiting syndrome. Methods: A 29-year-old female Korean patient with cyclic vomiting syndrome received acupuncture, electroacupuncture, herbal medicine, and moxibustion for 2 weeks in hospital. Changes in symptoms were evaluated using the Gastrointestinal Symptom Rating Scale (GSRS), Visual Analog Scale (VAS), Index for Nausea, Vomiting, and Retching (INVR), Nausea Severity Scale (NSS), Nepean Dyspepsia Index-Korean version (NDI-K), quality of life using the Functional Dyspepsia Related Quality of Life questionnaire (FD-QoL), and gastric motility using electrogastrography (EGG). Results: Post-treatment, the patient showed high satisfaction and improvement in symptoms of nausea and vomiting. The following changes were observed in scores: GSRS: 23 to 19; VAS of nausea: 88 to 95; VAS of dyspepsia: 95 to 12; INVR: 13 to 1; NSS: 17 to 5; NDI-K: 107 to 78; and FD-QoL 84 to 27. We also found positive results in Channel 3 of EGG parameters, implying the improvement of gastric motility disorder. Conclusion: Korean medical treatment can be a therapeutic option for cyclic vomiting syndrome.
