RESUMEN

Between 2000 and 2006, 85 adult BCR-ABL negative acute lymphoblastic leukaemia (ALL) patients between 18 and 60 years of age were treated using a modified paediatric regimen, which included high doses of asparaginase delivered weekly for 30 weeks during intensification. The complete response rate with induction therapy was 89%, and decreased with increasing age, mainly due to higher induction mortality. All post-induction treatments were delivered on an outpatient basis. The most common complications during intensification were infections (47%), osteonecrosis (32%), venous thromboembolism (23%) and neuropathy (22%). At a median follow-up of 4 years, the 5-year overall survival (OS) and relapse-free survival (RFS) were 63% and 71%, respectively. Significant adverse predictors for OS were age >35 years, high white blood cell count, MLL rearrangement, allogeneic stem cell transplantation in first complete remission and <80% of the planned asparaginase dose delivered during intensification. Patients aged < or = 35 years had a 3 year OS of 83%, as compared to 52% for patients aged >35 years. We conclude that the administration of this paediatric regimen is feasible and has considerable activity in adult ALL, particularly in younger patients. Effective delivery of asparaginase dosing appears to be important in achieving an optimal antileukaemic effect.

RESUMEN

We report a single center experience in treating 24 consecutive patients > or = 60 years old for aplastic anaemia (AA) with immunosuppressive therapy (IST). The main outcomes of interest were the tolerability and toxicity of IST, response rate and survival. Median age was 70 years (range 61-78). Seven patients received standard IST consisting of standard dose antithymocyteglobulin (ATG) with or without ciclosporin (CsA), and 17 patients received attenuated IST consisting of at least a 50% dose reduction of ATG with CsA or CsA alone. Six patients (25%) had early deaths, mostly due to infection. Early mortality appeared higher in the standard IST group although this was not statistically significant (43% vs. 18%, P = 0.4). The 2-year cumulative incidence of response was 42% [95% confidence interval (CI) 26-69%]. Responders had significantly better survival than non-responders (P = 0.0002). The 3-year probability of overall survival was 49% (95% CI 27-68%). Moderate or severe co-morbidities (P = 0.03) as determined by Charlson Co-morbidity Index and very severe AA (P = 0.007) were associated with significantly inferior overall survival while age was not. Nine out of 14 evaluable patients in the attenuated IST group had durable responses to treatment, suggesting that patients not suitable for standard IST can still benefit from attenuated IST.

RESUMEN

BACKGROUND: Young women receiving family planning services are at risk for both unintended pregnancy and herpes simplex virus type 2 (HSV-2) infection. METHODS: We performed a secondary analysis using data from a previously published randomized controlled trial evaluating access to emergency contraception on reproductive health outcomes. Women aged 15 to 24 years were recruited from two Planned Parenthood clinics and two community health clinics in San Francisco. Demographic information and sexual history were obtained by interview. HSV-2 seropositivity was determined by fingerstick blood test. New pregnancies were measured by self-report, urine testing and medical chart review. Subjects were evaluated for incident HSV-2 infection and pregnancy at a 6-month follow-up appointment. Women who were pregnant or intending to become pregnant at enrolment were excluded. RESULTS: At enrolment 2,104 women were screened for HSV-2 and 170 (8.1%) were seropositive. Eighty-seven percent of initially seronegative women completed the study (n = 1,672) and 73 (4.4%) became HSV-2 seropositive. HSV-2 seroincidence was 7.8 cases per 100 person-years. One hundred and seventeen women (7%) became pregnant and 7 (6%) of these had a seroincident HSV-2 infection during the study. After adjustment for confounders, predictors of incident HSV-2 infection were African American race and having multiple partners in the last six months. Condom use at last sexual encounter was protective. CONCLUSION: HSV-2 seroincidence and the unintended pregnancy rate in young women were high. Providers who counsel women on contraceptive services and sexually transmitted infection prevention could play an expanded role in counselling women about HSV-2 prevention given the potential sequelae in pregnancy. The potential benefit of targeted screening and future vaccination against HSV-2 needs to be assessed in this population.

RESUMEN

PURPOSE: To report a novel technique for safely closing antegrade common femoral artery (CFA) punctures using the StarClose device after proximal superficial femoral artery (SFA) angioplasty. TECHNIQUE: The vessel locator of the StarClose device should not be deployed within a recently dilated vessel, so after proximal SFA angioplasty, the sheath is withdrawn into the CFA. A second guidewire is inserted into the profunda femoris artery followed by insertion of the StarClose sheath. The vessel locator is deployed in the profunda main stem and withdrawn into the CFA until resistance is felt, indicating apposition to the luminal aspect of the vessel wall. The device is subsequently deployed according to the manufacturer's instructions. CONCLUSION: Use of profunda femoris artery allows safe closure of the CFA using the StarClose device following antegrade puncture for proximal SFA angioplasty.
