Spastic paraparesis associated with portal-systemic venous shunting due to congenital hepatic fibrosis.

We report a case of progressive spastic paraparesis in a 45-year-old man with total portal-systemic shunting, which developed spontaneously due to congenital hepatic fibrosis. Cellular functions of the liver, except for an elevated blood ammonia level, were within normal limits, as is usual in congenital hepatic fibrosis. This case shows that spastic paraparesis following portal-systemic shunting may occur without liver failure.

Adenosine deaminase activity in serum of patients with hepatitis -- a useful tool in monitoring clinical status.

BACKGROUND AND PURPOSE: The evaluation of adenosine deaminase (ADA) activity in sera of patients with hepatitis should be considered a useful tool in the monitoring of their clinical status. In this study, we aimed to determine the relationship between viral load, transaminase levels, and serum ADA levels in hepatitis B virus (HBV)- and hepatitis C virus (HCV)-infected patients. METHODS: Seventy three patients with hepatitis B, 71 patients with hepatitis C and 40 healthy individuals were included. Patients with HBV and HCV infections were classified into 3 groups according to viral load. Serum ADA levels were investigated by colorimetric assays. RESULTS: Serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), and ADA levels of HBV- and HCV-infected patients were higher than those of the control group. These differences were statistically significant for the levels of all enzymes in HCV-infected patients (p<0.05), and all except AST (p>0.05) in HBV-infected patients. ADA levels of HBV-infected patients with high viral loads were higher than those in HBV-infected patients with intermediate and low viral loads, and the difference was detectably significant between patients with high and intermediate viral loads. Evaluation of HCV-infected patients according to viral load showed no statistically significant relationship between viral load and serum ADA, ALT, and AST levels (p>0.05). HBV- and HCV-infected patients with high ALT and AST levels showed statistically significantly higher levels of ADA than patients with normal ALT and AST levels (p<0.001). CONCLUSIONS: We suggest that serum ADA levels are associated more with the level of serum transaminases than viral load in HBV- and HCV-infected patients. In the treatment of patients with hepatitis, serum ADA levels should be considered a useful tool for the monitoring of liver condition.

Contradictory effects of chlorpromazine on endothelial cells in a rat model of endotoxic shock in association with its actions on serum TNF-alpha levels and antioxidant enzyme activities.

We examined the effects of the phenothiazine derivative, chlorpromazine on thoracic aortic endothelial cell histology (14 h after LPS challenge) in a model of endotoxic shock in rats. Since excessive formation of tumor necrosis factor-alpha (TNF-alpha) and oxygen-derived free radicals contribute to endothelial injury in endotoxemia, we also evaluated the effect of the drug on the activities of antioxidant enzymes superoxide dismutase (SOD) and catalase in liver tissue in this model and tried to find out whether this possible effect was associated with a change in serum TNF-alpha levels (measured 90 min after chlorpromazine administration). Endotoxemia was induced by a single i.p. injection of lipopolysaccharide (LPS) (5 mg kg(-1) in 1.5 ml of saline; LPS from Escherichia coli serotype 055:B5, L-2880, Sigma Chemical Company). Electron microscopic evaluation of the aortas revealed that chlorpromazine (administered 30 min prior to LPS challenge), in smaller doses (3 mg kg(-1)) ameliorated the endothelial cell injury caused by LPS, whereas it caused deterioration of endothelial cell morphology in higher doses (10 and 25 mg kg(-1)). Chlorpromazine administration caused a significant reduction in serum TNF-alpha levels, which was correlated well with an increase in SOD activity in all drug doses (3, 10 and 25 mg kg(-1)). Catalase activity was increased only in the 25 mg kg(-1) chlorpromazine group.     

Outcomes after intravesical bacillus Calmette-Guerin are not affected by substaging of high grade T1 transitional cell carcinoma

PURPOSE: Substaging of T1 bladder tumors into T1a and T1b based on invasion of the tumor superficial to and beyond the muscularis mucosa has been assigned prognostic significance. We determined whether outcomes after intravesical bacillus Calmette-Guerin (BCG) differ between stage T1a and T1b subcategories. MATERIALS AND METHODS: Retrospective pathological evaluation of the initial transurethral resection specimens of stage T1 bladder tumors was performed by 2 pathologists. Grade 1, 2 or 3 and stage T1a or T1b were assigned to each case. Followup was from the date of transurethral resection to date of death or the last visit. Kaplan-Meier probability and log rank test were used to evaluate recurrence and progression. RESULTS: Substaging was performed in 49 of the 55 patients (89%) with stage T1 disease. Disease was stage T1a in 32 (65%), stage T1b in 17 (35%), grade 3 in 45 (92%) and grade 2 in 4 (8%) cases. Maximum followup was 147 months (median 71) and 28 cases had a minimum of 5 years of followup. Recurrence was noted in 33 cases (67.3%), including 22 stage T1a (69%) and 11 stage T1b (65%), at a median followup of 11.3 and 8.6 months, respectively. Progression to a higher stage of disease was recorded in 12 cases (24.4%), including 7 (22%) stage T1a and 5 (29%) stage T1b, at a median followup of 108 and 120 months, respectively. The difference between T1a and T1b subcategories was not statistically significant in regard to recurrence-free (p = 0.7203) and progression-free (p = 0.574) outcomes. CONCLUSIONS: Substaging of T1 tumors did not affect response to BCG in regard to recurrence or progression. Therefore, intravesical BCG is effective for stages T1a and T1b disease.     

Antibacterial and antifungal activities of some trimethoprim salts

In this study, the antimicrobial activities of Trimethoprim (1), Trimethoprim + Maleic acid (2), Trimethoprim + Oxalic acid dihydrate (3), and Trimethoprim + trans-1,2-Cyclohexanedicarboxylic acid (4) were investigated for their in vitro growth inhibitory activity against human pathogenic as some bacteria and fungi. Substances were tested using the micro-broth dilution assay. The chemical agents showed the same activity against Escherichia coli, Pseudomonas aeruginosa, and Proteus vulgaris. Inhibitory activities of test chemicals against different Candida strains were determined to be widely moderate.     

Evaluation of antinuclear antibodies by indirect immunofluorescence and line immunoassay methods′: four years′ data from Turkey

The presence of antinuclear antibodies (ANAs), directed against intracellular antigens, is a hallmark of systemic autoimmune rheumatic diseases. The indirect immunofluorescence (IIF) assay is among the most commonly used routine methods for ANA detection as the screening test. The objective of the study was to evaluate ANA patterns in a 4‐year period retrospectively. All 19 996 serum samples that were sent to the Laboratory of Medical Microbiology of the tertiary Hospital by any hospital department between 1 January 2009 and 1 January 2013 with a request to test for ANA, anti‐ENA or both were included in the study. Of these samples, 4375 (21.9%) were ANA‐IIF‐positive and 15621 (78.1%) were ANA‐IIF‐negative. The presented ANA‐positive samples consisted of 2392 (54.67%) homogenous, 818 (18.70%) speckled, 396 (9.05%) centromere, 242 (5.53%) nucleolar, 213 (4.87%) nuclear dots, 178 (4.07%) cytoplasmic (except for actin and golgi), 24 (0.55%) actin, 9 (0.21%) golgi, 53 (1.21%) nuclear membrane and 50 (1.14%) mixed pattern. Totally 7800 samples were examined by LIA. Of these samples, 3440 were positive and 4307 were negative with IIF and LIA. In addition, 22 samples were detected as IIF‐positive but LIA‐negative, whereas the rest 31 samples were IIF‐negative but LIA‐positive. ANA patterns in 22 IIF‐positive samples were homogenous (9), speckled (5), golgi (4), cytoplasmic (3) and nucleolar (1). SSA/Ro‐52, SSB/La and Scl‐70 positivity were detected in 31 IIF‐negative/LIA‐positive samples by LIA. The present study comes forward with its overall scope, which covers 4‐year data obtained in tertiary hospital located in the western part of Turkey.
