Tratamientos terapéutica de la fisura anal crónica

2005

Current treatment of chronic anal fissure continues to be based on conventional conservative measures in a high percentage of cases. What is known as chemical sphincterotomy aims to achieve a temporary decrease of anal pressures that allows fissures to heal. There are various alternatives such as nitroglycerine or diltiazem ointment and botulinum toxin injections. However, because of collateral effects and recurrences in the medium term, the definitive role of these treatments remains to be elucidated. Nevertheless, chemical sphincterotomy should be the first option in patients with a high risk of incontinence. "Open" or "closed" lateral internal sphincterotomy performed in the ambulatory s…

A retrospective analysis of pegylated liposomal doxorubicin in ovarian cancer: do we still need it?

2012

Abstract Background Ovarian cancer (OC) is the sixth most common cancer in women. Currently, carboplatin/paclitaxel ± bevacizumab is the cornerstone of front-line treatment. Conversely, the therapeutic options for recurrent or progressive disease are not well defined. For platinum-sensitive patients the best therapeutic approach is still a re-challenge with a platinum-based regimen. Pegylated liposomal doxorubicin (PLD), is considered one of the most active therapeutic options for recurrent or progressive OC. In this retrospective mono-institutional analysis, we evaluated the impact of PLD on the outcome of OC patients. Patients and methods We performed the retrospective study on a cohort o…

Nasal packing in posterior epistaxis. Comparison of two methods

2010

Objective: To evaluate tolerance and efficiency of two nasal blocking systems for posterior refractory epistaxis. Patients and methods: A five year comparative and longitudinal prospective study was developed in patients with epistaxis who attended our Emergency Unit and who required posterior nasal packing. Two groups were considered: one group was treated with a bi-chamber pneumatic inflation system (n=105). In the other one, posterior occlusion was carried out with gauze, accessing through the mouth and using nasal reinforcement (n=47). The tolerance was measured by means of an analogue scale of pain intensity during the placement and maintenance of the packing, as well as for the need o…

Dofetilide effects on the inhibition by trains of subthreshold conditioning stimuli.

2004

We investigated the electrophysiological actions of dofetilide upon the ventricular myocardium to determine whether the drug modifies the inhibitory effects of subthreshold stimuli trains upon ventricular refractoriness. In nine Langendorff perfused rabbit hearts, ventricular epicardial electrodes were used to determine the following parameters at baseline and during dofetilide perfusion (0.5 micromolar): effective (ERP) and functional (FRP) refractory periods, conduction velocity (CV), wavelength (WL), and ERP prolongation (inhibitory effect) induced by subthreshold stimuli trains (STr) at pulse frequencies of 100, 300, and 600 Hz. Dofetilide significantly prolongs ventricular refractorine…

Molecular Remission Can Be Attained in Relapsed or Refractory Chronic Lymphocytic Leukemia (CLL) and Follicular Lymphomas after Reduced Intensity Con…

2004

Abstract RIC followed by allo-SCT is an effective salvage treatment for some relapsed hematologic malignancies due to the postulated graft versus tumour (GVT) effect. In order to evaluate the quality of the clinical response, we have investigated the molecular status of patients receiving allo-SCT for relapsed disease. Forty-four patients (19 chronic lymphocytic leukemias (CLL), 21 follicular lymphomas (FCL) and 4 small lymphocytic lymphomas (SLL)) were enrolled in a prospective phase II study. The median age was 54 years (range: 32–69 years). The median number of previous chemotherapy regimens was 2 (range: 1–5) and 23% of patients had already failed an auto-SCT. Before transplant 34% of p…

Amsacrine with high-dose cytarabine is highly effective therapy for refractory and relapsed acute lymphoblastic leukemia in adults

1988

Abstract Thirty-six patients with relapsed acute lymphoblastic leukemia (ALL) and four with primary refractory ALL were treated with a regimen that included amsacrine, 200 mg/m2, intravenously daily for three days with cytarabine, 3 gm/m2, by infusion over three hours daily for five days. There were 27 remissions in the 36 relapsed patients and two in the four patients with primary refractory disease. Seventeen of the 23 patients with common ALL, four of the six with T-cell ALL, one of the three with B-cell ALL, and seven of eight whose cells were not characterized responded. Toxicity of this regimen was comparable to other reinduction regimens for ALL, but the side effects characteristic o…

Diagnosis, monitoring and management of immune-related adverse drug reactions of anti-PD-1 antibody therapy.

2015

PD-1 checkpoint inhibitors are associated with a specific spectrum of immune-related adverse events. This spectrum is different from toxicities known for kinase inhibitors or cytotoxic drugs. Since PD-1 directed therapies show effectivity in an increasing number of malignant diseases, their clinical usage will increase rapidly. Therefore clinicians from different specialities such as medical oncology, internal medicine, family doctors and emergency unit staff should be aware of the adverse effects of PD-1 checkpoint inhibitors to avoid delays in diagnosis and treatment. Based on pooled data from pivotal trials as reported by the European Medicines Agency, the present paper reviews incidence…

Caplacizumab prevents refractoriness and mortality in acquired thrombotic thrombocytopenic purpura: integrated analysis

2021

Abstract The efficacy and safety of caplacizumab in individuals with acquired thrombotic thrombocytopenic purpura (aTTP) have been established in the phase 2 TITAN and phase 3 HERCULES trials. Integrated analysis of data from both trials was conducted to increase statistical power for assessing treatment differences in efficacy and safety outcomes. Caplacizumab was associated with a significant reduction in the number of deaths (0 vs 4; P < .05) and a significantly lower incidence of refractory TTP (0 vs 8; P < .05) vs placebo during the treatment period. Consistent with the individual trials, treatment with caplacizumab resulted in a faster time to platelet count response (ha…

A retrospective study of 72 cases diagnosed with idiopathic trigeminal neuralgia in indian populace

2014

Context: Trigeminal neuralgia is as a chronic, debilitating condition, which can have a major impact on quality of life. There are few reports of trigeminal neuralgia in oriental populations. Objectives: To evaluate the retrospective data of the patients diagnosed with idiopathic trigeminal neuralgia and to understanding the disorder in the Indian populace. Methods: The retrospective data of 72 patients with typical idiopathic trigeminal neuralgia regarding age of onset, gender, site of involvement, clinical presentations and treatment received during three years of the follow up was collected and analyzed. Results: In the present retrospective study, the mean age was 54.9 years; female to …
