Reporting endometrial cells in women 40 years and older: assessing the clinical usefulness of Bethesda 2001

We assessed the usefulness of revised Bethesda System reporting of exfoliated benign endometrial cells (EMs) in postmenopausal women. Cervicovaginal cytology specimens with benign EMs in postmenopausal women and "out-of-phase EMs" in premenopausal women 40 years and older were identified. Cases with histologic follow-up within 12 months were selected. There was tissue follow-up for 130 postmenopausal women: 10 (7.7%) had significant findings (endometrial adenocarcinoma, 6 [2 (33%) in asymptomatic women]; complex atypical endometrial hyperplasia [CAH], 3; leiomyosarcoma, 1); 20 were receiving hormone replacement therapy (HRT; n = 15) or tamoxifen (n = 5); 2 (10%) had significant pathology (endometrial adenocarcinoma, 1; CAH, 1). Eight not taking hormones (7.3%) had significant pathology (adenocarcinoma, 5; CAH, 2; leiomyosarcoma, 1). There were follow-up data for 96 premenopausal women; only 1 (who had vaginal bleeding) had significant pathology (CAH). The difference in incidence of preneoplastic and neoplastic conditions after a cytologic interpretation of "benign EM" between postmenopausal and premenopausal women was significant (P pound .025); There was no difference between postmenopausal women receiving or not receiving HRT (P > .05). Reporting benign EMs for premenopausal women 40 years and older has no clinical significance but does for postmenopausal women, regardless of HRT and symptoms.     

Human polyoma virus in renal allograft biopsies: morphological findings and correlation with urine cytology.

Human polyoma virus (PV) interstitial nephritis occurs in immunosuppressed patients after reactivation of latent virus in renal epithelium. Currently, there is neither general consensus about the incidence of clinically significant PV infection in renal transplants nor conclusive evidence determining its significance in the long-term graft outcome. We evaluated 601 renal transplant biopsy specimens (from 365 patients) by routine light microscopy and immunoperoxidase stains with antibody against SV40 (which cross reacts with PV). We also examined urine samples from 200 patients (100 obtained concurrently with a renal biopsy in patients presenting with acute graft dysfunction and 100 from patients with stable graft function). Electron microscopic evaluation was performed in 50 renal biopsy specimens and in 23% of all urine samples. PV was identified in 1.8% biopsy specimens (1.9% of patients). PV interstitial nephritis showed the typical viral cytopathic changes in tubular epithelial cells associated with marked tubular damage and a disproportionately mild degree of tubulitis. There was no difference in the incidence of PV in the urine of patients with acutely deteriorating versus stable renal function (18% and 19%, respectively); however, urines with large numbers of infected cells (> 10/cytospin) and inflammatory changes in the sediments corresponded invariably to patients with acute allograft dysfunction (8 of 8), and in most cases to biopsy specimens showing PV interstitial nephritis (7 of 8). Based on these findings, urine samples seem to be the most sensitive and cost-effective screening method for PV infection; only urine samples with inflamed sediments and abundant infected cells correlate with clinically significant disease. In these cases, examination of a renal biopsy is indicated. Immunohistochemical stains are useful to confirm the presence of PV but do not increase the sensitivity of diagnosis of PV if this is not already suspected on routine light microscopy. In our material, immunostains were helpful ruling out the presence of PV in a small number of biopsy specimens (2%) that showed markedly reactive tubular cells resembling PV infection. Most patients with PV interstitial nephritis responded to decreased immunosuppression; however, the decay in graft function (based on creatinine slopes) was significantly more rapid in these patients than in matched controls. Evidence of PV infection should be systematically sought in renal biopsy specimens and urine samples from renal allograft recipients.     

Intrahepatic biliary cystic neoplasms: Surgical results of 9 patients and literature review

AIM: To investigate the eligible management of the cystic neplasms of the liver. METHODS: The charts of 9 patients who underwent surgery for intrahepatic biliary cystic liver neoplasms between 2003 and 2008 were reviewed retrospectively. Informed consent was obtained from the patients and approval was obtained from the designated review board of the institution. RESULTS: All patients were female with a median (range) age of 49 (27-60 years). The most frequent symptom was abdominal pain in 6 of the patients....     

Prognostic factors for upper urinary tract urothelial carcinomas: stage,grade, and smoking status

Objectives  

Upper urinary tract urothelial carcinomas are relatively rare malignancies. The aim of this study was to investigate the factors affecting prognosis of patients undergoing nephroureterectomy.     

Comparison of Efficacy of Neural Therapy and Physical Therapy in Chronic Low Back Pain

The aim of this prospective study was to evaluate the effects of neural therapy, and physical therapy on level of pain, disability, quality of life, and psychological status in patients with chronic low back pain. Patients admitted to the physical therapy and rehabilitation outpatient clinic with the complaint of low back pain of at least 3 months duration. Group 1 (n=27), physical therapy (PT, hotpack, ultrasound, TENS 15 sessions), group 2 (n=33), neural therapy (NT, 1:1 mixture of 20 mg/mL Lidocaine HCl (Jetokain simplex®) and saline for 5 sessions. For pain, Visual Analogue Scale (VAS), for disability Roland Morris Disability Questionnaire (RMDQ), for quality-of-life Nottingham-Health-Profile (NHP), for depression, and anxiety, Hospital Anxiety-Depression Scale (HADS) were used before and after the treatment. Mean age was 47.3±11.32 years, symptom time was 13.78±11.98 months. There were no differences for demographic variables between groups. Significant improvements were detected for VAS, RMDQ, NHP-Pain, NHP-Physical activity, HADS for both of two groups after treatment. In addition to these findings, significant improvements were found for NHP-Energy, NHP-Social isolation in NT group. The differences of pre- and post-treatment values of parameters were evaluated for each group. Although there were no differences for VAS, NHP-sleep, NHP-Emotional reaction, HADS between groups, RMDQ, NHP-Pain, NHP-Physical activity, NHP-Social isolation were higher in NT than PT before treatment, the improvements for these parameters were better in NT than PT. In conclusion both of NT and PT are effective on pain, function, quality of life, anxiety, and depression in patients with chronic low back pain.     

Atorvastatin affects C-reactive protein levels in patients with coronary artery disease

BACKGROUND: Elevated levels of C-reactive protein (CRP) are considered to be one of the indicators of poor prognosis in coronary artery disease (CAD). The aim of this study was to evaluate anti-inflammatory effects of atorvastatin in patients with CAD by measuring serum CRP levels. METHODS: After measuring the baseline levels of CRP and lipid fractions, the patients were divided into two groups. In Group A (n = 46), atorvastatin (20 mg/day) was administered in addition to classic antianginal treatment (beta-blocker, nitrate and aspirin). In Group B (n = 32), the usual antianginal treatment was continued. Following 4 weeks of treatment the same measurements were repeated. RESULTS: In Group A, CRP decreased from 20.3 mg/dl (95% CI, 9-31.8) to 10.8 mg/dl (95% CI, 2.7-18.9) (p < 0.001). In Group B, CRP decreased from 17 mg/dl (95% CI, 13.1-21) to 12.8 mg/dl (95% CI, 9.7-15.9) (p < 0.01). The decrease in group A was more than in group B (p = 0.003). CONCLUSIONS: In patients with CAD, atorvastatin exerted an anti-inflammatory effect represented by decreasing CRP levels. This effect was independent of the change in low density lipoprotein cholesterol (LDL-C) or high density lipoprotein cholesterol (HDL-C) levels.
