    Notizen: This paper presents new findings on ultrasonic spray pyrolysis of zirconium hydroxyl acetate precursor drops whose sizes were precisely measured using laser light diffraction technique. Precursor concentration plays a predominant role in determination of product particle size. At 0.01 wt% precursor concentration, conventional spray pyrolysis at 750°C using precursor drops 5–8 μm in diameter, generated by an ultrasonic nebulizer at 2.66 MHz, yielded uniform spherical yttria-stabilized zirconia (YSZ) particles 73 nm in diameter measured by scanning electron microscopy. The YSZ particle diameters were much smaller than those predicted by the one-particle-per-drop mechanism. Under similar reaction conditions, the high-throughput ultrasound-modulated two-fluid (UMTF) spray pyrolysis of larger precursor drops (28-μm peak diameter) also yielded spherical dense particles; they were significantly smaller in size than those produced by the low-throughput conventional ultrasonic spray pyrolysis of smaller drops (6.8-μm peak diameter).

    Notizen: Background : Irritable bowel syndrome is a common condition seen in Western countries. In Asia, however, it is less known and even less studied.Aim : To determine the prevalence and social impact of irritable bowel syndrome as well as the health-seeking behaviour of irritable bowel syndrome patients in TaiwanMethods : Using the modified Rome II questionnaire, a survey was carried out in a population receiving physical check-up (n = 2865).Results : The prevalence of irritable bowel syndrome in Taiwan was 22.1% and 17.5% (κ = 0.73) according to the Rome II and I criteria, respectively. No gender difference was found between subjects with and without irritable bowel syndrome symptoms. Irritable bowel syndrome subjects were likely to undertake an excessive number of physician-visits (P 〈 0.01). Such subjects were often absent from work/school, with more days of absenteeism than irritable bowel syndrome-free subjects (P 〈 0.01). They also suffered obvious sleep disturbance (P 〈 0.01). Nearly half of the irritable bowel syndrome subjects were ‘consulters’, and they were more likely to have frequent physician-visits, suffer from work/school absenteeism, and endure sleep disturbance and bowel symptoms than irritable bowel syndrome nonconsulters (P 〈 0.05).Conclusions : Irritable bowel syndrome is common in a Chinese population of Taiwan. Similar to irritable bowel syndrome in the West, it also involves significant social and medical burdens. However, in the irritable bowel syndrome subjects of Taiwan there is no gender difference, and more irritable bowel syndrome subjects will seek physician consultations, which may be due to Taiwan's easily accessible and affordable heath care facilities.

    Notizen: Aim : To study the potential risk factors leading to peptic ulcer disease among autoimmune disease patients on corticosteroid treatment.Methods : One hundred and thirty-eight corticosteroid-treated autoimmune disease patients were enrolled; their demographic data were recorded and laboratory data were measured. Endoscopy was performed to assess the occurrence of peptic ulcer disease. Helicobacter pylori infection was diagnosed on the basis of rapid urease test and histological examination.Results : Twenty-eight (20%) of 138 autoimmune disease patients had peptic ulcer disease, including 17 with gastric ulcer, eight with duodenal ulcer and three with gastric ulcer plus duodenal ulcer. Eighty five (62%) had used non-steroidal anti-inflammatory drugs and 46 (33%) had H. pylori infection. The majority of peptic ulcer disease subjects showed the following characteristics: age ≥ 60 years; male; smokers; non-steroidal anti-inflammatory drug users, particularly the non-specific cyclo-oxygenase inhibitors; presence of hyperpepsinogenaemia I; low H. pylori colonization (P 〈 0.05). Multivariate analysis revealed that an age ≥ 60 years [odds ratio (OR), 6.80; P = 0.001], smoking (OR, 7.94; P = 0.004) and the use of non-specific cyclo-oxygenase inhibitors (OR, 4.71; P = 0.030) were the predominant risk factors for the development of peptic ulcer disease among these patients, whereas H. pylori infection showed a protective role (OR, 0.20; P = 0.022).Conclusions : Old age, smoking and the use of non-specific cyclo-oxygenase inhibitors are risk factors for peptic ulcer disease in autoimmune disease patients on corticosteroid treatment. H. pylori infection appears to protect against peptic ulcer disease in these patients.

    Thema: Medizin
    Notizen: Background : Saliva plays a role in mucosal protection and ulcer healing.Aim : To study whether decreased salivary production leads to peptic ulcer disease in connective tissue disease patients associated with xerostomia.Patients and methods : Two hundred and two connective tissue disease patients (90 with xerostomia and 112 without xerostomia) were enrolled. Their demographic data and use of medications were recorded. Peptic ulcer disease was confirmed by endoscopy. The stimulated salivary output and secretory epidermal growth factor level were measured.Results : Compared with non-xerostomic counterparts, xerostomic patients manifested a higher occurrence of peptic ulcer disease (31% vs. 12%, P = 0.001), lower stimulated salivary output (9.3 ± 4.1 vs. 22.9 ± 5.9 mL/15 min, P 〈 0.001) and lower stimulated salivary epidermal growth factor output (1.40 ± 0.77 vs. 3.00 ± 0.96 ng/min, P 〈 0.001). Multivariate analysis disclosed that an older age (≥ 60 years) (odds ratio, 4.71; P 〈 0.001), xerostomia with stimulated salivary output of ≤1 mL/min (odds ratio, 7.54; P = 0.014) and the use of non-steroidal anti-inflammatory drugs (odds ratio, 5.76; P = 0.031) were the risk factors leading to peptic ulcer disease. In addition, xerostomic connective tissue disease patients receiving non-steroidal anti-inflammatory drugs manifested an extremely high risk of development of peptic ulcer disease (odds ratio, 19.78; P 〈 0.001).Conclusions : Ageing, the use of non-steroidal anti-inflammatory drugs and poor salivary function are potential risk factors for the development of peptic ulcer disease in patients with connective tissue disease. If these xerostomic subjects consume non-steroidal anti-inflammatory drugs, they will encounter an extremely high peptic ulcer disease risk.

    Thema: Medizin
    Notizen: Abstract Objective: This paper presents a field evaluation of 3 M 3500 passive badges for measuring 2-methoxyethanol (ME) in a humid working environment. Methods: A total of 93 pairs of side-by-side active/passive samples, 48 pairs of duplicate active samples, 52 pairs of duplicate passive samples, and three groups of six replicate active/passive samples were compared. Three groups of six replicate active charcoal/active charcoal tube with drying tube samples were also compared to evaluate the humidity effect. Results: No statistical difference was found between the passive badges and active samplers. Linear regression showed the correlation to be high (r = 0.992, slope  =  0.973, n = 93) over the range of 0.17–163 ppm. The mean concentration difference was −0.34 ppm and the mean relative error was 3.50%. The intraclass correlation coefficients of 48 duplicate active samples and 52 duplicate passive samples were 0.994 and 0.989, respectively. The precision of replicate passive, active, and active/drying tube samples (n = 6) were 3.84%, 7.14%, and 5.12%, respectively. Conclusions: The humidity effect for active samples was insignificant at the low sampling rate (36.3 ml/min). It is therefore concluded that the use of the passive samplers to assess ME exposure produces comparable findings to that of active sampling.

    Notizen: Abstract  Cerebral dural sinus thrombosis (CDST) is a very rare complication of acute lymphoblastic leukemia (ALL) in adult patients. A 23-year-old man with ALL developed dizziness, headache, diplopia, limb weakness, and a sensation of fullness in his head after his second induction chemotherapy with doxorubicin, prednisolone, and vincristine. Examinations of the peripheral blood, bone marrow, and cerebrospinal fluid showed no recurrent leukemic cells. Magnetic resonance (MR) imaging of the brain disclosed unexpected CDST at the left transverse sinus, which was seen only on the fast fluid-attenuated inversion recovery (FLAIR) sequence. His symptoms were relieved soon after treatment with heparin. MR imaging with FLAIR performed a second time 7 days later showed complete disappearance of the thrombosis. The patient was treated continuously with oral anticoagulant therapy and the symptoms did not recur. CDST can be diagnosed in its early phase by MR studies with FLAIR images. Anticoagulant therapy can be administered safely without precipitating the occurrence of infarction hemorrhage at such an early stage of CDST.
