INTRODUCTION: Mutations of hepatitis B virus (HBV) polymerase, especially occurring at the highly conserved YMDD region, are related to resistance to lamivudine. Although these mutations are frequently secondary to lamivudine use, they can also occur naturally. The aim of the present study was to determine the prevalence of YMDD variants that exist naturally in patients who are inactive HBV carriers. METHODS: Seventy-one adult inactive HBV carriers were studied. All of the patients were confirmed to have maintained normal alanine aminotransferase (ALT) values for one or more years by monitoring serum ALT levels at 3-monthly intervals. None of the patients received interferon or antiviral agents. YMDD variants were analyzed by the HBV Drug Resistance Line Probe assay (Inno-Lipa HBV-DR). RESULTS: YMDD variants were detected in 13 (18.3%) of the 71 anti-HBe positive inactive HBV carriers. Of the 13 patients, 10 (76.9%) also had accompanying L180M mutation. The combination of wild type and YMDD variant HBV was present in 11 of 13 patients. In two patients, only YIDD and/or YVDD variants plus L180M were detected without the presence of wild YMDD motif. CONCLUSION: Naturally occurring YMDD motif variants were detected at a high rate in a group of lamivudine-untreated inactive HBV carriers. 相似文献

PURPOSE: To evaluate the relationship between varicocele and chronic obstructive pulmonary disease (COPD) via color duplex sonography. MATERIALS AND METHODS: Forty-four male patients with COPD (age range, 50-89 years; mean +/- SD, 66 +/- 9) and 44 male healthy controls (age range, 47-75 years; mean +/- SD, 65 +/- 6) were evaluated with color duplex sonography for unilateral or bilateral varicocele. RESULTS: The incidence of right, left, and bilateral varicocele was 47.7%, 65.9%, and 38.6% respectively, in the COPD group, versus 22.7%, 52.3%, and 13.6% in the control group. The incidence of right and bilateral varicocele in the COPD group was significantly higher than in the control group (p < 0.05). The incidence of varicocele also increased with increase in COPD severity. CONCLUSIONS: The incidence of varicocele in COPD patients is high. Varicocele might be one of the most important causes of scrotal pain and infertility in COPD patients. 相似文献

The epidemiology of salivary gland tumors worldwide is not very well defined. Although many studies on this subject have been undertaken, the data are generally focused on specific topics such as parotid gland neoplasms or tumors of the major salivary glands. We conducted a study to establish the prevalence and distribution of benign and malignant neoplasms of both the major and minor salivary glands at a single institution. We reviewed 244,204 cases that had come through our pathology department from January 1994 through December 2005 and found 235 cases of a salivary gland neoplasm (0.09%). The female-to-male ratio was 1.04:1, and the mean age of the patients was 47 years. Of the 235 neoplasms, 159 (67.66%) were located in the parotid gland, 34 (14.47%) in the submandibular gland, and 42 (17.87%) in the minor salivary glands. A total of 146 tumors (62.13%) were benign and 89 (37.87%) were malignant. Pleomorphic adenoma was the most common neoplasm, occurring in 98 cases (41.70%). The most common malignancy was mucoepidermoid carcinoma, with 27 cases (11.49%). Our data demonstrate that the characteristics of salivary gland tumors in a Turkish population at a single institution are similar to those reported in the literature worldwide. 相似文献

Introduction We evaluated the safety and efficacy of the Angio-Seal closure device used to close arterial puncture sites in patients who
had undergone diagnostic cerebral angiography and neurointerventional procedures.
Methods A total of 1,443 Angio-Seal devices were placed in 1,099 patients in the Interventional Neuroradiology Unit between May 2005
and August 2006. Of these, 670 were interventional and 745 were diagnostic cerebral angiographic procedures. In 28 patients
bilateral puncture of the femoral arteries was performed for endovascular treatment. In 167 patients 286 repeat diagnostic
procedures were performed and 30 interventional procedures were followed by re-closure with an Angio-Seal device at the time
of repeat puncture.
Results The procedural success rate for antegrade closures was 99.7% for all procedures. The device failed in 5 of 745 diagnostic
procedures (0.7%). Major complication occurred in one patient only (0.13%) in the diagnostic group. No minor complications
were observed in this group. In the interventional group, the major complication rate was 1.4% (10 of 698 closures) and the
minor complication rate was 2.4% (17 of 698 closures). However, in the subgroup of patients with cerebral aneurysms who received
heparin in combination with antiplatelet agents after the procedure, the major complication rate was 5.3%, but in the carotid/vertebral
stenting group it was 0.8%.
Conclusion Our experience in a relatively large series of patients shows that the use of the Angio-Seal STS vascular closure device is
safe and effective in patients undergoing cerebral diagnostic angiography and neurointerventional procedures with an acceptable
rate of complications, although the complication rate was higher in the group of patients who received heparin and/or antiplatelet
medication. 相似文献

Primary diffuse leptomeningeal oligodendrogliomatosis is a rare malignancy of central nervous system without evidence of a
primary intraparenchymal focus. We present a 25-year-old woman with the postmortem diagnosis of primary diffuse leptomeningeal
oligodendrogliomatosis. She was paraplegic and had sensory loss at the level of thoracal 8–9 for nearly 15 months. There was
no symptom due to increased intracranial pressure. Unexpectedly she died just before biopsy. Autopsy revealed a nodular lesion
at the level of thoracal 10 vertebra and diffuse oligodendroglioma throughout the leptomeninges of the brain and spine without
intraaxial focus. To our knowledge, this is the first case of primary diffuse leptomeningeal oligodendrogliomatosis causing
sudden death in the literature. 相似文献

OBJECTIVES: Lumbosacral radiculoplexus neuropathy (DLRPN) is a rare form of neuropathy observed in diabetic and rarely non-diabetic patients. Pathophysiology and lesion location are not clearly understood. Our aim was to analyze proximal and distal femoral conductions in patients with DLRPN. METHODS: Six patients with DLRPN, 14 patients with diabetic polyneuropathy and 25 healthy subjects were included in the study. We performed L3 monopolar root stimulation and femoral nerve trunk stimulation at the inguinal region and calculated lumbar plexus conduction time by subtracting the latency of compound muscle action potential (CMAP) of the vastus medialis evoked by femoral nerve stimulation from the latency of CMAP of vastus medialis evoked by L3 root stimulation. Additionally peak to peak amplitudes and areas of CMAPs were analyzed. RESULTS: Electrophysiological examination showed that there was an axonal involvement in all patients with DLRPN. Prolonged lumbar plexus conduction time (in five extremities), and prolonged distal latency of the femoral nerve (in five extremities) probably due to secondary demyelination were also observed. Similar abnormalities were not observed in the diabetic polyneuropathy group. CONCLUSIONS: DLRPN may affect different localizations on the peripheral nerves. L3 root stimulation may have an important role in the electrodiagnosis of DLRPN. 相似文献
