    Subcutaneous emphysema, pneumomediastinum and pneumothorax complicating laparoscopic vagotomy (1993)

    Notes: Two patients developed subcutaneous emphysema and pneumomediastinum during laparoscopic vagotomy. One of the patients also had a pneumothorax which produced a sudden increase in end-tidal carbon dioxide concentration preceding arterial oxygen desaturation. The pneumothorax was drained with an intercostal cannula. The patient required a twofold increase in minute ventilation to maintain normocarbia, probably because of the additional absorption of carbon dioxide through the pleural cavity. Despite the presence of a peritoneopleural communication, surgery was successfully completed. We believe that gas under tension in the peritoneal cavity dissected along tissue planes around the oesophagus opened up during surgery. Thus pneumomediastinum, subcutaneous emphysema and pneumothorax are definite risks associated with this new procedure.

    Notes: summary  The aim of this study was to subjectively determine the distribution of anaesthesia by mapping areas of sensory loss following inferior alveolar nerve block. Fifty healthy dental students were the subjects of this study (men 32, women 18). They were asked to draw the anaesthetized area on a diagram of the face and tongue 20 min after inferior alveolar nerve block. They evaluated the degree of anaesthesia by touching their faces and moving their tongues. All of the 50 subjects reported anaesthesia in the facial area. Of these, 21 (42%) reported the cutaneous distribution of anaesthesia on mental nerve territory only. Seventeen subjects (34%) reported anaesthesia on mental and buccal nerve territory. Nine subjects (18%) reported anaesthesia on mental, buccal, and auriculotemporal nerve territory. Two subjects (4%) reported anaesthesia on mental and auriculotemporal nerve territory and one subject (2%) on mental, buccal and infra-orbital nerve territory. Forty-seven of the 50 subjects (94%) reported anaesthesia of the tongue with the various degree of anaesthesia according to the area. Of these, 17 subjects (34%) reported strong anaesthesia on the anterior area and weak anaesthesia on the middle part of the tongue. Nineteen subjects (38%) reported strong anaesthesia of the lateral area and weak anaesthesia on the medial area, and 11 subjects (22%) reported anaesthesia on only the lateral side of the tongue. Three subjects (6%) reported no anaesthesia of the tongue. The distribution of anaesthesia of the facial and glossal regions determined subjectively after inferior alveolar nerve block, varies significantly between individuals.

    Notes: summary  The aim of this study was to identify the salivary components present in the pellicles formed on self-curing resin and to investigate the qualitative variations in adsorbed salivary pellicle compositions according to different exposure time to saliva. Experimental pellicles were formed by the incubation of polymerized resin particles with fresh human parotid or submandibular-sublingual saliva for either 20 min or 2 h. Pellicles were extracted using formic acid and lyophilized, they were then subjected to sodium dodecyl sulphate–polyacrylamide gel electrophoresis and immunoblotting to identify the adsorbed salivary components. The amino acid profiles of the 2 h-pellicles were analysed and compared with those of fresh glandular salivas. There was a difference in the 2 h-pellicle components on the self-curing resin compared with those of other dental materials as well as tooth enamel. The amino acid profiles of the 2 h-pellicles were also different from those of fresh glandular salivas. In the case of submandibular-sublingual saliva, the components of the 2 h-pellicle showed a different pattern compared with those of the 20 min-pellicle. However, there was no significant difference between the components of the 2 h- and 20 min-pellicles in the case of parotid saliva. A distinct difference was found in the surface binding affinities of immunoglobulin (IgA) from different glandular salivas. The findings of this study provide information concerning the initial bacterial adhesion on the surfaces of self-curing resin.

    Notes: The performance of the 1 m Seya–Namioka monochromator (1 m-SNM) beam line at SRRC has been measured and reached the designed goal. The beam line throughput (photon flux) has been measured by a calibrated silicon photodiode and is close to the theoretical values. The resolving power of this beam line has been measured from the studies of the core absorption of Ar and Ne and the Rydberg states of Mg vapor gas, and has reached the theoretical values. The improvement of the cooling system of the first mirror is also described. © 1995 American Institute of Physics.

    Notes: : We have previously shown that ranitidine bismuth citrate (RBC)-based triple therapy is comparable to proton pump inhibitor-based triple therapy in eradicating Helicobacter pylori infection.〈section xml:id="abs1-2"〉〈title type="main"〉Aim: To test the efficacy of different combinations of antimicrobials with RBC in the treatment of H. pylori infection.〈section xml:id="abs1-3"〉〈title type="main"〉Methods: Dyspeptic patients with H. pylori infection were prospectively randomized to receive one of the following regimens: (i) RBC 400 mg, amoxycillin 1 g, clarithromycin 500 mg [RAC]; (ii) RBC 400 mg, metronidazole 400 mg, clarithromycin 500 mg [RMC]; (iii) RBC 400 mg, metronidazole 400 mg, tetracycline 1 g [RMT] (all given twice daily for 1 week); or (iv) RBC 400 mg plus clarithromycin 500 mg twice daily for 2 weeks [RC-2]. Endoscopy (rapid urease test and culture) and 13C-urea breath test (UBT) were performed before randomization. Four weeks after finishing medication, the 13C-UBT was repeated in all cases and endoscopy was offered to patients with peptic ulcers.〈section xml:id="abs1-4"〉〈title type="main"〉Results: Four hundred patients were randomized but in two (one in the RAC group and one in the RMC group) H. pylori infection was not confirmed. Successful eradication of H. pylori (intention-to-treat analysis and 95% CI) of RAC (86% [79–93%]), RMC (90% [84–96%]), RMT (79% [71–87%]) and RC-2 (82% [75–90%]) were comparable, with a trend favouring clarithromycin-containing triple therapy regimens. Among 276 isolates tested for antibiotic sensitivity, primary resistance to metronidazole, clarithromycin and amoxycillin was found in 56%, 2% and 0.4%, respectively. When given RMC or RMT, patients infected by metronidazole-resistant H. pylori had success in eradicating H. pylori similar to patients infected by metronidazole-sensitive H. pylori.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusion: One-week RBC triple therapy is effective in curing H. pylori infection.

    Notes: Performance of commercial serological tests for Helicobacter pylori varies in different populations, largely due to strain heterogeneity and variations in antigenic preparations. Currently available serology tests often show sub-optimal accuracy when used for Asian patients.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:This study evaluated a recombinant antigen-based immunoblot for the diagnosis of H. pylori infection in Chinese patients, and compared it with a conventional ELISA test.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:Dyspeptic patients referred for diagnostic endoscopy were recruited. The gold standard for H. pylori infection was based on two or more positive results among rapid urease test, histology and 13C-urea breath test. Serological diagnosis of H. pylori infection was conducted by an ELISA test (pylori DTect; Diagnostic Technology) and an immunoblotting against a novel recombinant antigen (C1S; Genelab), which was constructed by immunological screening of the genomic DNA library of H. pylori.〈section xml:id="abs1-4"〉〈title type="main"〉Results:A total of 87 patients were evaluated and H. pylori infection was diagnosed in 40 (46%) by the reference tests. The sensitivities of the ELISA and immunoblot were 80% (95% CI: 64–91%) and 90% (95% CI: 76–97%), whilst the specificities were 96% (95% CI: 86–96%) and 87% (95% CI: 74–95%), respectively. The respective likelihood ratios of the two tests were 18.6 and 7.0.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:Satisfactory performance is obtained by the use of the new recombinant antigen-based immunoblot for diagnosing H. pylori infection in Chinese patients.

    Notes: Prophylactic misoprostol or non-steroidal anti-inflammatory drugs (NSAIDs) with low gastric toxicity (nabumetone) has been shown to reduce mucosal injury.〈section xml:id="abs1-2"〉〈title type="main"〉Aim:To compare nabumetone vs. co-therapy of naproxen with low-dose misoprostol for secondary prevention of upper gastrointestinal bleeding in NSAID users.〈section xml:id="abs1-3"〉〈title type="main"〉Methods:NSAID users presenting with upper gastrointestinal bleeding were enrolled if they required long-term NSAIDs. After ulcer healing, they were randomized to receive: naproxen (500–1000 mg/day) and misoprostol (200 μg b.d.), or nabumetone (1000–1500 mg/day) and placebo misoprostol for 24 weeks. The primary end-point was recurrent upper gastrointestinal bleeding. The secondary end-point was the proportion of patients suffering from major gastrointestinal events including ulcer bleeding, symptomatic ulcers and severe dyspepsia.〈section xml:id="abs1-4"〉〈title type="main"〉Results:A total of 90 patients were included in the intention-to-treat analysis (misoprostol/naproxen 45, nabumetone 45). Recurrent bleeding occurred in 10 patients (22.2%) receiving misoprostol/naproxen compared with three (6.7%) receiving nabumetone (relative risk 3.33, 95% CI: 0.98–11.32, P=0.069). The proportion of patients suffering from major gastrointestinal events at 24 weeks was 31.1% in the misoprostol/naproxen group and 28.9% in the nabumetone group.〈section xml:id="abs1-5"〉〈title type="main"〉Conclusions:Misoprostol/naproxen is not superior to nabumetone for secondary prevention of upper gastrointestinal bleeding. Neither low-dose misoprostol nor nabumetone is adequate for high-risk NSAID users.
