Alteration of the TAL1 locus is the most common nonrandom genetic defect in childhood T-cell acute lymphoblastic leukemia (T-ALL). To determine if rearrangements of the TAL1 proto-oncogene confer a distinct leukemic phenotype, we studied leukemic peripheral blood or bone marrow samples from 182 children with newly diagnosed T-ALL enrolled on Pediatric Oncology Group treatment protocols. Forty-eight (26%) of the samples had a local rearrangement of the TAL1 locus. Demographic and clinical features were compared for patient subgroups with and without TAL1 rearrangements. The only clinical correlates that were significantly associated with TAL1 gene rearrangements were higher white blood cell count (P = .017) and higher hemoglobin (P = .007) at diagnosis. Immunophenotypically, samples with altered TAL1 were more likely to be CD2+ (P = .001) and lack CD10 (cALLa) expression (P = .007) than those without the rearrangement. There was a trend toward improved event-free survival (EFS) in patients with TAL1 rearrangements (4-year EFS was 44% +/- 7% for patients without the rearrangements v 59% +/- 11% for those with rearrangements), but the difference was not significant (P = .34). The role of TAL1 in leukemogenesis has yet to be clearly defined, and the prognostic significance of TAL1 gene rearrangements in T-ALL deserves further study. 相似文献

Effect of antiviral treatment in patients with chronic HCV infection and t(14;18) translocation 总被引:6,自引:1,他引:6

Hepatitis C virus (HCV) may be associated with the mixed cryoglobulinemia syndrome and other B-cell lymphoproliferative disorders (LPDs). The t(14;18) translocation may play a pathogenetic role. Limited data are available regarding the effects of antiviral therapy on rearranged B-cell clones. We evaluated the effects of interferon and ribavirin on serum, B-lymphocyte HCV RNA, and t(14; 18) in 30 HCV+, t(14;18)+ patients without either mixed cryoglobulinemia syndrome or other LPDs. The t(14;18) translocation was analyzed by both bcl-2/JH polymerase chain reaction and bcl-2/JH junction sequencing in peripheral blood mononuclear cells in all patients. Fifteen untreated patients with comparable characteristics served as controls. Throughout the study, the presence or absence of both t(14;18) and HCV RNA sequences were, in most cases, associated in the same cell samples. At the end of treatment, t(14;18) was no longer detected in 15 patients (50%) with complete or partial virologic response, whereas it was persistently detected in nonresponders (P <.05), as well as in 14 of 15 control patients. In 4 responder patients, t(14;18) and HCV RNA sequences were no longer detected in blood cells after treatment, but were again detected after viral relapse; the same B-cell clones were involved in the pretreatment and posttreatment periods. In conclusion, this study suggests that antiviral therapy may induce regression of t(14;18)-bearing B-cell clones in HCV+ patients and that this phenomenon may be related, at least in part, to the antiviral effect of therapy. This in turn suggests that antiviral treatment may help prevent or treat HCV-related LPDs. 相似文献

We report on two daughters and a son of a Thai family who were affected with BWS. Their clinical findings consist of cleft palate, omphalocele, anterior ear creases, indented lesions on the posterior rim of the helix, macroglossia, posterior crossbite, and anterior open bite. The younger daughter and son had newly recognized findings of the BWS including sensorineural hearing loss and supernumerary flexion creases of the fingers. A novel mutation in CDKN1C (c.579delT; p.A193AfsX46) was found in all affected individuals and their mother. This mutation is located in the central highly polymorphic hexanucleotide repeat encoding a proline‐alanine series of repeats (PAPA‐domain). This domain is involved in MAP kinase phosphorylation. This is for the first time that sensorineural hearing loss and supernumerary flexion creases of the fingers are associated with mutation in CDKN1C. © 2012 Wiley Periodicals, Inc. 相似文献

IntroductionWe evaluated the reproducibility of video endoscopic inguinal lymphadenectomy (VEIL) and we report our initial experience in the treatment of penile cancer with palpable inguinal lymph nodes.Material and methodsFrom July 2006 to November 2010 were conducted 33 VEIL in 20 patients as complementary treatment for penile cancer in two referral hospitals in Latin America. We analyzed the epidemiological and clinical characteristics of patients and surgical and oncologic outcomes.ResultsFifty-five percent of the patients included were clinical stage N0 and 45% were N +. Thirteen patients underwent bilateral VEIL and the remaining seven underwent VEIL unilateral and conventional open surgery in the contralateral limb. The average operative time for VEIL was 119 minutes and mean resected lymph nodes was 8 per lymphadenectomy. The overall complication rate was 33.2%. No patient had skin necrosis. The lymphatic complication rate was 27.2%. Of the 6 cases in which the saphenous vein was preserved (18.2%) there were no lymphatic complications (P = ,2). The overall survival rate was 80% and cancer-specific survival was 90%. Mean follow-up was 20 months.ConclusionsVEIL in the adjunctive treatment of penile cancer is safe, reproducible and may be an alternative to conventional lymphadenectomy. Patients with palpable lymphadenopathy also may benefit from this technique. Oncological results seem to be adequate however require longer follow-up to be confirmed. 相似文献

The aim of the present study was to assess the periodontal treatment needs of the population that spontaneously sought treatment from general dentists. 3694 patients (2000 females and 1494 males, age range between 18 and 84 years) were evaluated using the Community Periodontal Index (CPI). Data were reported according to the percentage of subjects with the highest Score: 14.3% presented pocket depth > or = 5.5 mm (Score 4), 26.4% pocket depth between 3.5 and 5.5 (Score 3), 38.3% presented pockets < or = 3.5 mm with calculus or overhanging restorations (Score 2), 17.2% pockets < or = 3.5 mm with bleeding upon probing without calculus (Score 1) and 3.2% were healthy (Score 0). Analyzing the data according to age it was observed that in the group > 40 years the percentage of patients with Score 4 was higher (25.1%) compared to the other two groups of 18-34 years (6.4%) and 34-45 years (14.3%). Only 16.4% of the patients consulted for periodontal reasons (gingival bleeding or tooth mobility), whereas 88% requested treatment for other reasons (pain, caries, esthetics, replacement of teeth, etc.). However 77% of the patients in this last group needed periodontal treatment. 96.8% of the patients attending the general dentistry office needed periodontal treatment: 17.2% oral hygiene instruction, 65.2% oral hygiene instruction and scaling and 14.3% complex treatment. 相似文献

IntroductionDislocation following total hip replacement continues to be a problem for which no completely satisfactory solution has been found. Several methods have been proposed to reduce the incidence of hip dislocations with varying degrees of success, including elevated rim liners, constrained liners and large diameter bearings. We present our experience with the double mobility acetabular component in patients at high risk of instability.MethodsThis was a retrospective review of 65 primary total hip arthroplasties in 55 patients (15 men, 40 women), performed between October 2005 and November 2009. The majority (80%) of patients had at least two and 26% had at least three risk factors for instability. The mean age was 76 years (range: 44–92 years). The patients were followed up for a mean duration of 60 months (range: 36–85 months).ResultsFourteen patients died and one was lost to follow-up, leaving fifty hips for final assessment. Until the final follow-up appointment, no patients had dislocation and none required revision surgery. The mean Oxford hip score improved from 45.0 to 26.5 (p<0.0001). The mean Merle d’Aubigné pain score improved from 1.4 to 4.9 (p<0.0001), the walking score from 2.3 to 3.1 (p<0.07) and the absolute hip function score from 5.4 to 10.8 (p<0.0001). There were no clinical or radiographic signs of loosening.ConclusionsThe double mobility acetabular component was successful at preventing dislocation during early to medium-term follow-up. However, as data are still lacking with regard to polyethylene wear rates at the additional bearing surface, it would be prudent to restrict the use of this implant to selected patients at high risk of instability. 相似文献
