In enteroclysis the flow rate of the barium is important but not easily controlled with an infusion bag system. To improve the technique, an electric flow inducer was used in 156 consecutive examinations to infuse the barium suspension at a constant rate of 75 ml/min. Detailed demonstration of mucosal folds was achieved in 90 per cent. The examinations were of moderate quality in 8 per cent and of poor quality in 2 per cent. The maximum transit time was 20 minutes and the total examination time never exceeded 35 minutes. Sensitivity and specificity were 94 and 97 per cent, respectively. Examinations indicated by specific small bowel symptoms had a positive yield of 49 versus 13 per cent with non-specific indications. Both examination performance and patient tolerance were improved.

Background: To evaluate the accuracy and the pitfalls of frozen section examination in diagnosis the common tumors at Hue University Hospital. Materials and method: A retrospective analysis data of 99 consecutive patients from 2007 to 2009 were evaluated and analyzed the major pitfalls. In our 99 patients, 100% cases we compared histological diagnosis on frozen sections with those on paraffin sections. Results: The majority of frozen section examinations were the thyroid lesions 37.4%, breast lesions 25.2%, lymph nodes 16.1%, ovary 9.1% and less common in other diseases (12.1%). The accuracy, sensitivity and specificity of the intraoperative frozen section examination were 93.9%, 89.1% and 98.1% respectively. The main factors causing incorrect diagnosis in frozen section are: Misinterpretation, poor quality of frozen sections, improper sampling in sectioning and difficult to result interpretation. Conclusion: The frozen section analysis of suspect lesions displays good sensitivity and specificity characteristics.

Abstract Background and study aims Ultrathin endoscopes are commonly used for surveillance esophagogastroduodenoscopy (EGD) to reduce discomfort associated with scope insertion. However, the flexibility of an ultrathin endoscope is a trade-off between reducing discomfort and lengthening examination time. Patients and methods The EG17-J10 (EG17) is a novel ultrathin endoscope characterized by its tapering body stiffness; however, the flexibility of its tip is comparable to that of the traditional ultrathin endoscope EG16-K10 (EG16). We compared EGD examination time between EG17 and EG16. A total of 319 examinees who underwent EGD from November 2019 to January 2020 at the Chiba-Nishi General Hospital were enrolled. Six examinees were excluded due to past history of surgical resection of the upper gastrointestinal tract or too much food residues; 313 examinees (EG17, 209; EG16,104) were retrospectively analyzed. The examination time was divided into three periods: esophageal insertion time (ET), gastroduodenal insertion time (GDT), and surveillance time of the stomach (ST). The total amount of ET, GDT, and ST was defined as total examination time (TT). Results TT of EGD using EG17 was significantly shorter compared to EGD using EG16 (222.7 ± 68.9 vs. 245.7 ± 78.5 seconds) (P = 0.004). Among the three periods of examination time, ET (66.7 ± 24.1 vs. 76.0 ± 24.1 seconds) (P = 0.001) and GDT (47.9 ± 17.4 vs. 55.2 ± 35.2 seconds) (P = 0.007) of EGD using EG17 were significantly shorter compared to EGD using EG16, except for ST (108.1 ± 51.5.1 vs. 114.5 ± 50.1 seconds) (P = 0.148). Conclusion An ultrathin endoscope with tapering body stiffness can shorten EGD examination time, mainly due to the shortening of insertion time.

Children demonstrating a radiologic malabsorption pattern on small bowel follow-through study performed for other reasons are frequently subjected to intensive gastrointestinal investigations, even in the absence of clinical manifestations of malabsorption. To determine the usefulness of this radiologic finding, the clinical findings of all patients with the typical malabsorption pattern on small bowel follow-through examination were reviewed retrospectively. The presence of a malabsorption pattern was based on three radiologic criteria: flocculation and segmentation of barium, thickening of mucosal folds, and dilation of intestinal loops. Thirteen patients fulfilled the criteria for radiologic malabsorption pattern, but six (46%) had no clinical evidence of malabsorption, according to 3- to 5-day fecal fat analysis. In addition, five of these patients had normal mucosal histologic findings on duodenal biopsy. It was concluded that radiologic malabsorption pattern is a nonspecific finding, and in the absence of other clinical features suggestive of malabsorption or growth failure further investigations may not be justified.

The inspired oxygen fraction (FIO2) delivered by the Hudson Oxy-one face mask was measured under changing conditions of ventilation, oxygen flow rate to mask, and mask fit. A single trained subject sat in a body plethysmograph to measure ventilation and breathed at a constant rate of 15 per minute at three different tidal volumes, of approximately 0.3, 0.6, and 1.2 litres, from the mouthpiece in the plethysmograph. The Oxy-one face mask was fitted to a plaster-of Paris face model on the outside of the plethysmograph in a loose and then in a tight fashion. Oxygen concentration was continuously monitored from a point in the metal tube connecting the face model to the mouthpiece. The tightly fitting mask demonstrated an orderly reduction in FIO2 as ventilation increased and oxygen flow rate to the mask decreased. The mean FIO2 at a ventilation of 4.5 l.min-1 and 8 l.min-1 oxygen flow was 78% and this fell to 27% at a ventilation of 16 l.min-1 and oxygen flow of 2 l.min-1. The loosely fitting mask demonstrated larger SD of measurements and lower mean maximum FIO2 values of 46 to 49% and these fell in an irregular fashion to similar minimum values as ventilation increased and oxygen flow decreased. Although the precise definition of the FIO2 for each breath from the changing concentration during each inspiration was not possible, these results indicate that FIO2 changes in a predictable way as a function of ventilation and oxygen flow, if the mask is close fitting. This method could be conveniently used to study other oxygen delivery systems.

The aim of this work is to study the minimization of the environmental impact associated with the gasification of sewage sludge. Co-gasification of a poor quality coal with dried sewage sludge was undertaken on a lab-scale gasifier. The presence of sewage sludge in co-gasification with coal led to higher energy conversions and the gas produced had greater hydrocarbons content. Both temperature and air flow rate were increased with the objective of giving rise to higher energy conversion, thus producing more gas, maximizing hydrogen formation and lowering hydrocarbons, char and tar contents. Due to the adverse effects of the presence of N, S and Cl pollutant precursors leading to the presence of highly corrosive compounds in the syngas, their conversion was evaluated. The increase of sewage sludge content in the feedstock was found to enhance the production of NH3, but working at higher temperatures and with greater Equivalence Ratio (ER) promoted the destruction of NH3. Production of H2S was similar for sewage sludge and coal and seemed to have been decreased by the presence of large quantities of ashes containing Ca and Fe. Temperature had no significant influence on H2S, but higher ER lowered H2S in the syngas. HCl was low and did not varied significantly for the conditions studied. The bed char residues were characterized and their leachability behaviour was evaluated. Heavy metals supplied with the fuel were mostly retained in solid residues, Pb and Hg being the most volatiles at 850°C. However, leachability of these metals was found to be below the analytical detection levels and only small quantities of SO42− and Cl− were released. The bed char residues were found to have variable concentrations of residual C, hence they could be used either as fuels to provide energy for gasification reactions or as sorbents to capture volatile heavy metals.
