Background. It is known that Helicobacter
pylori (Hp) plays an important role in gastritis and peptic
ulcer disease in the general population. Although dyspeptic complaints are
frequent in haemodialysis (HD) patients and renal transplant recipients,
there are few reports regarding the prevalence of Hp and its possible
effects on this group of patients. This study was performed to examine the
prevalence of Hp infection in patients on regular HD treatment and to
detect its role in the pathogenesis of dyspepsia in this group of patients.
Methods. Two hundred and one patients with dyspeptic
complaints were included in the study. The groups consisted of 47 HD, 54
renal transplant recipients, and 100 non-renal disease patients. Upper
gastrointestinal endoscopies were performed and gastric antral biopsies
were obtained for urease test in all patients.
Results. Twenty-eight (60%) of the 47 HD and 28 (70%)
of the 54 RTR were positive for Hp. Sixty-four (64%) of the 100 patients
with various gastrointestinal complaints and known to have no renal
dysfunction were positive for Hp. The Hp prevalences among the three groups
were not significantly different (P <0.05). The prevalence of Hp
infection did not correlate with the haemodialysis duration nor the
post-transplantation duration (P <0.05). There was no correlation
between the prevalence of Hp infection and duration of haemodialysis
therapy or time post-transplantation. Conclusion.
These findings suggest that HD patients are not protected against Hp
infection as the Hp prevalences are as high as that for the non-renal
disease group. The increased dyspeptic complaints may be partly related to
Hp infection. 相似文献

OBJECTIVE: This study evaluates the vocal cord and arytenoid mobility in relation to the tumoral involvement of the cricoarytenoid joint (CAJ), thyroarytenoid (TA) muscle, and posterior cricoarytenoid (PCA) muscle in whole-organ sections of total laryngectomy specimens. STUDY DESIGN AND SETTING: The study was prospectively carried out between 1998 and 2003 and involved 133 primary squamous cell carcinoma cases of larynx or pyriform sinus that were treated with total laryngectomy. Preoperative mobility of vocal cords and arytenoids were evaluated separately and correlated with histopathologic findings. RESULTS: In cases with fixed vocal cord CAJ, TA muscle, and PCA muscle were involved in 42.4%, 72.9%, and 27.1% of the cases, respectively, while in cases with fixed arytenoid these structures were affected in 40%, 66.3%, and 25.3% of the cases. Weight effect seemed to play a role in 60% and 50% of the cases of supraglottic and pyriform sinus carcinoma, respectively. CONCLUSION: Careful evaluation of the mobility of the cord arytenoid unit separately helps the surgeon to better understand the patterns of tumoral extension guiding for the appropriate surgery which should be undertaken. 相似文献

BackgroundIt is extremely difficult to treat spine disorders with stabilization in patients with rheumatoid arthritis. Because revision rates are significantly higher in rigid stabilization. To date, there is no data about patients with rheumatoid arthritis treated with dynamic stabilization. Our aim was to compare the radiological and clinical results of patients with rheumatoid arthritis who underwent lumbar rigid stabilization or dynamic stabilization with Polyetheretherketone rod (PEEK).MethodsPatients with degenerative lumbar spine disease with rheumatoid arthritis who underwent dynamic stabilization between 2013 and 2015 and rigid stabilization between 2010 and 2012 were evaluated radiologically for adjacent segment disease, proximal junctional kyphosis, system problem (nonunion, screw loosening, instrumentation failure, pull out). It was also compared according to both the revision rates and the Visual Analog Scale and Oswestry Disability Index scores at the 12th month and 24th month.ResultsThe difference of decrease in Visual Analog Scale and Oswestry Disability Index scores from preoperative to 12th month between patients who underwent dynamic stabilization and rigid stabilization was statistically insignificant. However, there was a significant difference of increase in Visual Analog Scale and Oswestry Disability Index scores between the 12th month and 24th month of patients who underwent rigid stabilization, compared with patients with dynamic stabilization. In patients with dynamic stabilization, the problems of instrumentation were seen less frequently. Revision rates were high in patients with rigid stabilization when compared the patients with dynamic stabilization.ConclusionRadiological and clinical outcomes in patients with rheumatoid arthritis operated with dynamic stabilization are more significant when compared to rigid stabilization. These patients have lower pain and disability scores in their follow up periods. Revision rates are lower in patients with dynamic stabilization. 相似文献

Following a brief review of embryogenesis and phylogenesis, the different anatomical structures of the temporal lobe of the brain are described. This lobe has 4 surfaces: lateral, inferomedial, superomedial and superior. The first 2 surfaces, visible on the lateral and inferior aspects of the cerebral hemisphere, are composed of 5 temporal gyri. The superomedial and superior surfaces do not show and must be made visible by a digital or instrumental manipulation. The hippocampal formation, surrounded by the temporal horn of the lateral ventricle medially, the choroid and transverse fissures laterally and the amygdaloid complex anteriorly, forms the superomedial surface and represents the "rhincendephalic" part of the temporal lobe. The superolateral surface, which is the superior surface of the first temporal gyrus, is buried deeply in the fissure of Sylvius and is divided into 3 parts: the planum polare, the gyri of Heschl and the planum temporale. Two categories of fibres are present in the white matter of the temporal lobe: projection fibres (acoustic radiation, optic radiation, temporo-pontine tract, temporo-thalamic fasciculus) and association fibres (cingulum, anterior longitudinal, uncinate, superior occipitofrontal, superior longitudinal fasciculi). The anatomical temporal lobe exploration by MRI was carried out with inversion-recovery sequences performed in all three dimensions. The authors describe the advantages and limitations of MRI and indicate the most appropriate plane(s) for the study of the various temporal structures, with emphasis on coronal on coronal and sagittal sections. 相似文献

BACKGROUND.: Although chronic hepatitis C infection is one of the factorsthat can lead to morbidity and mortality in renal allograftrecipients, treatment procedures have not been well documented.Interferon treatment has been shown to be effective in the normalizationof biochemical hepatitis C and in the clearing of hepatitisC virus RNA. However, little is known concerning the efficacyand safety of interferon treatment in renal allograft recipientswith chronic hepatitis C. Interferon has also been accused ofincreasing renal allograft rejection. METHODS.: Recombinant -interferon in a dose of 4.5 million units threetimes per week was given to five renal-allograft recipientswith chronic hepatitis C for 6 months. Besides biochemical investigations,liver histopathologies before and after the treatment coursewere also studied. RESULTS.: Interferon treatment was effective in two of the patients, inanother two cases renal function deteriorated during the treatment.In the last case ALT increased again after cessation of interferontherapy. CONCLUSION.: We conclude that interferon seems to be moderately effectivein treating chronic hepatitis C in renal allograft recipients,but a risk of renal functional deterioration and rejection remains. 相似文献

BACKGROUND AND PURPOSE: Single agent mitomycin c (MMC) has been shown to improve the outcome of radiotherapy in single institution trials. In order to confirm these findings in a broader worldwide setting, the International Atomic Energy Agency (IAEA) initiated a multicentre trial randomising between radiotherapy alone versus radiotherapy plus MMC. MATERIAL AND METHODS: Patients with advanced head and neck cancer were treated with primary curative radiotherapy (66 Gy in 33 fractions with five fractions per week) +/-a single injection (15 mg/m(2)) of MMC at the end of the first week of radiotherapy. Stratification parameters were tumour localization, T-stage, N-stage, and institution. A total of 558 patients were recruited in the trial from February 1996 to December 1999. Insufficient accrual and reporting led to the exclusion of three centres. The final study population consisted of 478 patients from seven centres. Patients had stage III (n=223) or stage IV (n=255) squamous cell carcinoma of the oral cavity (n=230), oropharynx (n=140), hypopharynx (n=65) or larynx (n=43). Prognostic factors like age, gender, site, size, differentiation and stage were well balanced between the two arms. RESULTS: The haematological side effects of MMC were very modest (<5% grade 3-4) and did not require any specific interventions. Furthermore, MMC did not enhance the incidence or severity of acute and late radiation side effects. Confluent mucositis and dry skin desquamation was common, occurring in 56% and 62% of patients, respectively. The overall 3-year primary locoregional tumour control, disease-specific and overall survival rates were 19, 36 and 30%, respectively. Gender, haemoglobin drop, tumour site, tumour and nodal stage were significant parameters for loco-regional tumour control. There was no significant effect of MMC on locoregional control or survival, except for the 161 N0 patients, where MMC resulted in a better loco-regional control (3-year estimate 16% vs. 29%, P=0.01). CONCLUSIONS: The study did not show any major influence of MMC on loco-regional tumour control, survival or morbidity after primary radiotherapy in stage III-IV head and neck cancer except in N0 patients where loco-regional control was significantly improved. 相似文献

One of the most common craniofacial malformations observed in newborn babies is cleft lip and palate (CLP). This syndrome presents with some anatomic variations. The aim of this study was to understand an anatomic variation of the crista galli that had not been reported previously in patients with CLP. A 17-year-old boy with CLP was referred to an orthodontic clinic for cone-beam computed tomography (CBCT) imaging before treatment. Axial and coronal sections and three-dimensional images showed that the crista galli had bifid heads that were attached to each other. Incomplete ossification had resulted in a bifid crista galli and the appearance of a suture in the anterior coronal section of the CBCT images. This anatomic variation could allow penetration of the anterior fossa during endoscopic surgery, which could be dangerous for the patient. 相似文献
