OBJECTIVE: The aim of this study was to determine the prevalence and risk factors for peptic ulcer disease (PUD) in dyspeptic patients with ischemic heart disease (IHD), and to assess whether the healing of PUD before coronary artery bypass grafting (CABG) could reduce the need for urgent postoperative endoscopy. PATIENTS AND METHODS: A series of 894 patients referred to Dubrava University Hospital in Zagreb for elective CABG during the period from May 1998 until April 2001 was prospectively analysed. Dyspepsia was assessed by a questionnaire, PUD by upper gastrointestinal endoscopy, and H. pylori status by histology/Giemsa staining and the rapid urease test. The need for urgent postoperative endoscopy (hematemesis and/or melena, sudden onset of anemia or unexplained epigastric pain) was compared between the prospective study group of 894 patients and a series of 463 patients referred for CABG to Dubrava University Hospital during the period from January 1997 until April 1998. RESULTS: Gastroduodenal dyspepsia predominated in 184 (20.6 %) patients, 142 (77.2 %) of them with Helicobacter (H.) pylori infection and 69 (37.5 %) with verified PUD. Univariate analysis indicated the increased risk of multiple PUD to be related to a previous diagnosis of PUD (OR 3.61, 95 % CI 1.32 - 9.82), H. pylori infection (OR 18.86, 95 % CI 2.31 - 153.98), use of aspirin (OR 5.70; 95 % CI 1.80 - 18.03) and left coronary artery occlusions (3.10, 95 % CI 1.00 - 9.59). Multivariate analysis pointed to H. pylori infection (OR 16.30, 95 % CI 1.57 - 168.53) and left coronary artery occlusions (OR 4.84, 95 % CI 1.05 - 22.30) as independent risk factors for multiple PUD. The OR for urgent postoperative endoscopy due to a major gastrointestinal event was 9.9 (95 % CI 2.2 - 45.1) and the OR for active peptic ulcer with stigmata of recent bleeding was 6.9 (95 % CI 1.4 - 33.1) in the group of patients with IHD who were not submitted to evaluation for dyspepsia prior to elective heart surgery. CONCLUSIONS: In areas with a high prevalence of H. pylori infection, endoscopy and a "search and treat" strategy for IHD patients with dyspepsia before elective cardiac surgery should significantly reduce the need for urgent postoperative endoscopy due to major gastrointestinal events. 相似文献

Finding that estrogen plays an important role in bone homeostasis in men prompted research on relationship of polymorphism at the CYP19 gene and the bone mass. Therefore, influence of 3-bp deletion/insertion polymorphism of CYP19 (TTTA)7 allele on the peak bone mass attainment in males was studied. Fifty-eight unrelated male participants, aged 21-35, were selected depending on the presence of (TTTA)7 (no.=19) or (TTTA)7-3 (no.=39) alleles from the initial cohort of 92 young males. Heterozygotes (TTTA)7/(TTTA)7-3 (no.=13) were not included in the analysis. Serum levels of estradiol, free testosterone, 25-hydroxyvitamin D, bone alkaline phosphatase, osteocalcin, and beta-crosslaps were measured. Bone mass was measured by DXA at the hip and at the spine. (TTTA)7-3 allele was associated with significantly lower femoral neck bone mineral density (BMD) (p=0.02). Logistic regression model indicated strong association of (TTTA)7-3 allele with low BMD in the range of osteopenia/osteoporosis (p=0.014, odds ratio 12.36, confidence intervals 1.65-92.46). In the present study association of 3-bp deletion polymorphism of the (TTTA)7 allele with decreased peak bone mass in males is reported for the first time. However, further studies are necessary to elucidate the functional relevance of this polymorphism. 相似文献

Long-term cultures of mouse bone marrow cells were treated with naloxone, starting at the time of culture initiation or in
the 2nd or 4th week of culture. Cell proliferation was suppressed and the ratio of immature and mature granulocytes to macrophages
diminished by naloxone treatment. The effect depended on the timing of naloxone addition to the cultures and on its concentration,
with a bell-shaped dose-response curve. High and low concentrations of naloxone (10−4, 10−6, 10−14 M) interfered with hematopoiesis more strongly than the intermediate concentrations (10−8 to 10−12 M). Early cultures lacking the stromal layer were more sensitive to naloxone than the cultures with established stroma. The
bell-shaped dose-response curve has been attributed to an interplay of specific (opioid-receptor-mediated) and nonspecific
mechanisms. Opioidergic mechanisms apparently participate in the regulation of hematopoiesis. 相似文献

BACKGROUND: Postoperative nausea and vomiting (PONV) occurs frequently after strabismus surgery. The controversy still exists regarding the association of PONV and the oculocardiac reflex (OCR). A recent study has proven that rocuronium attenuates OCR. If these two occurrences are dependent, it is expected that with the diminution of OCR, occurrence of PONV will also be reduced. The goal of this randomized, controlled study was to prove an association between OCR and PONV by attenuating OCR with 0.4 mg x kg(-1) of rocuronium and subsequently diminishing PONV if these occurrences are associated. METHODS: A total of 119 ASA 1 children, aged between 3 and 10, undergoing surgery of the medial rectus muscle, were randomly assigned to two groups. In group R (n = 59), 0.4 mg x kg(-1) of rocuronium was administered i.v. before intubation. Group C (controls, n = 60) received no muscle relaxant. The anesthesia was induced and maintained with halothane and N(2)O/O(2) (50/50%). Chi-squared test, Fisher's exact test, t-test, and anova were used for statistical analysis; P-value <0.05 was considered statistically significant. RESULTS: There were no differences between groups regarding patients' characteristics as well as endtidal halothane and duration of surgery and anesthesia. The occurrence of OCR was different between groups (R: 16/59, 27.1%, C: 28/60, 46.7%; P = 0.027), but not the occurrence of PONV (R: 27/59, 45.8%, C: 28/60, 46.7%; P = 0.921). There was an equal number of patients with PONV and bradycardias in both groups (R: 4/27 vs C: 4/28; P = 0.858), whereas there was different, but statistically insignificant distribution of patients (R: 3/27 vs C: 10/28; P = 0.086) with PONV and arrhythmias other than bradycardia. However, simultaneous occurrence of total OCR and PONV in the 24-h period was not different between the two groups (P = 0.964). CONCLUSIONS: Rocuronium (0.4 mg x kg(-1)) attenuates the occurrence of OCR, but with the reduced occurrence of OCR we were not able to attenuate the occurrence of PONV, therefore the association of OCR and PONV in strabismus surgery in children anesthetized with halothane and nitrous oxide remains unclear, and if there is a link between the two, it could be related to arrhythmias and not bradycardia. 相似文献

Limited number of dual X-ray absorptiometry (DXA) devices in Croatia makes this diagnostic technique unavailable to the majority of the population. Quantitative ultrasound (QUS) of the calcaneus could be an alternative tool for assessing fracture risk. However, age-specific normative data should be obtained before using the QUS in everyday clinical practice. The aim of our Epidemiology of Calcaneus Ultrasound in Males (ECUM) study is to establish the normative QUS data in a healthy sample of Croatian males. A total of 1002 male participants, aged 20-99, recruited in different Croatian counties, were included in the study. In each subject broadband ultrasound attenuation (BUA), speed of sound (SOS) and quantitative ultrasound index (QUI) of the left calcaneus were measured using the Sahara ultrasound device (Hologic). The coefficients of variation were 2.85 for BUA, 0.37 for SOS and 2.49 for QUI. Significant declining with age was found for all three parameters, BUA (p<0.001), SOS (p<0.001) and QUI (p<0.001), with respective r values 0.14, 0.27 and 0.23. The peak SOS (1,562.8+/-28.5 m/sec) and QUI (103.6+/-16.5) values were observed in the third decade, whereas the peak BUA value (86.2+/-19.2 db/MHz) was observed in the fourth decade. A subgroup of 103 participants, aged 20-29, was used to estimate young adult mean and SD for QUI and calculate the T-scores. Using the World Health Organization diagnostic criteria the rates of osteoporosis (T-score<-2.5) in the males aged 50 and older was 5.8%. However, when we used the cut-off value of the T-score<-1.8, as previously suggested, prevalence of osteoporosis in Croatian males >50 yr was 16.2%. Although further studies might improve our understanding of the QUS role in the fracture prediction, we hope that the results presented here will improve the clinical management of osteoporosis in males. 相似文献

It is well known that several psychiatric disorders may be related to childhood psychological trauma. Recent studies have associated childhood exposure to trauma to some skin diseases. Our study aimed at exploring whether psoriasis is related to the reported positive and negative traumatic life events in different age intervals beginning from early childhood to adulthood. Furthermore, we investigated differences between psoriatics with early and late onset according to traumatic experiences in different age intervals. Also, we investigated the possible correlation of traumatic experiences with the disease severity. One hundred patients with psoriasis and 101 controls (patients with skin conditions considered to be "non-psychosomatic") were enrolled in the study. All participants completed a specific questionnaire measuring traumatic life experiences (Traumatic Antecedents Questionnaire, TAQ). The TAQ assesses positive personal experiences (competence and safety) and negative personal experiences (neglect, separation, secrets, emotional, physical and sexual abuse, trauma witnessing, other traumas and exposure to alcohol/drugs) from early childhood to adulthood. The severity of psoriasis was estimated according to the Psoriasis Area and Severity Index (PASI), a standardized measuring instrument. The amount of positive experiences did not differ significantly among groups, except for safety scores that were higher in controls compared with both psoriatic groups (early and late onset). On the other side, negative traumatic experiences appeared more frequently in patients with psoriasis during all developmental periods. We found no correlation between severity of psoriasis and traumatic experiences. The present study demonstrates an increased history of childhood and adulthood negative traumatic experiences in patients with psoriasis compared to the control group. Our findings suggest a relationship between retrospectively reported negative traumatic experiences and psoriasis. 相似文献

Growth hormone (GH) deficiency and acromegaly serve as good models for investigating the effects of GH on bone remodeling. However, the results from various studies are rather conflicting. The aim of our study was to estimate the potential role of gender, disease activity, and duration on both calcaneus quantitative ultrasound (QUS) parameters and bone turnover markers in patients with acromegaly. Thirty-six acromegalic patients (17 men, 19 women) and 3 age- and gender-adjusted controls for every patient were included in the study. The disease was active in 22 patients, and was considered cured in 14 of them. In each subject, QUS of the heel and parameters of bone turnover (bone alkaline phosphatase, beta-crosslaps, and osteocalcin) were measured. The results demonstrated lower QUS values in acromegalic patients compared with the controls. When stratified by gender, the differences in QUS parameters were significant in men, but not in women. Male patients with active disease had significantly lower QUS values than those in remission. Such differences were not observed among women. Multiple regression model indicated strong association between disease activity and the QUS parameters. The group of patients with active disease had a higher level of serum beta-crosslaps, whereas osteocalcin concentration was significantly increased only in male patients with active disease. The results of our study suggest significantly lower QUS values and increased bone turnover in male patients with active acromegaly. The disease activity is the strongest predictor of the QUS parameters in acromegalic patients. 相似文献
