Pharmacological management of cancer pain in children

2014

The aim of this review was to assess cancer pain management in children on the basis of research published in the last ten years. Nine were papers providing clinical data, with a minimum of ten patients. No controlled studies were found. Regardless of general principles and existing recommendations, clinical data should confirm the applicability of this concept. The trials published in the last years did not provide further information to improve cancer pain management in children, because of the experience and the low number of drugs used, reflecting only meaningful opinions of experts in the field. The amount and the quality of data still remain poor, as only 737 subjects (about 80 patien…

The effects of morphine on the temporal structure of Wistar rat behavioral response to pain in hot-plate

2016

Rationale: The largest amount of researches on the hot-plate test was carried out using quantitative assessments. However, the evaluation of the relationships among the different elements that compose the behavioral response to pain requires different approaches. Although previous studies have provided clear information on the behavioral structure of the response, no data are available on its temporal structure. Objectives: The objective of this study was to investigate the temporal structure of the behavioral response to pain in Wistar rat tested in hot-plate and how this structure was influenced by morphine-induced analgesia. Methods: The behavior of four groups of subjects tested in hot-…

Pain intensity as prognostic factor in cancer pain management

2015

Aim The aim of this study was to prospectively assess the prognostic value of initial pain intensity and its duration in advanced cancer patients. Methods A prospective study was conducted in a sample of patients with cancer requiring pain control. Patients underwent standard analgesic strategies used in our palliative care units. Pain intensity was measured at admission (T0) and after successful dose titration or opioid/route switching within a week (Ts). Patients were also asked about their pain intensity reported 15 days before admission (T-15). Doses of opioids and duration of opioid use were recorded. Patients were also assessed for the presence of incident pain, neuropathic pain, alco…

Clinical and financial analysis of an acute palliative care unit in an oncological department

2008

The aim of this article is to describe the clinical activity and medical intervention of an acute model of palliative care unit (APC), as well as the reimbursement procedures and economic viability. A sample of 504 patients admitted at an APC in 1 year was surveyed. Indications for admission, pain and symptom intensity, analgesic treatments, procedures, instrumental examinations and modalities of discharge were recorded. For each patient, tariff for reimbursement was calculated according to the existent disease related grouping (DRG) system. The mean age was 62 years, and 246 patients were males. The mean hospital stay was 5.4 days. Pain control was the most frequent indication for admissi…

Opioid metabolism and clinical aspects.

2015

Opioids are are commonly used for the management of acute and chronic pain. Opioids have different physicochemical and pharmacokinetic characteristics, which explain the profound changes in the clinical effect in several clinical conditions. Pharmacokinetics influences the opioid response affecting bioavailability, production of metabolites with residual clinical activity, and elimination. Generality of opioid metabolism and clinical implications for specific opioids in different clinical conditions were reviewed to bridge the gap between pharmacokinetics and clinical response. The knowledge of opioid metabolism is essential, particularly for older and complicated patients who receive multi…

Opioid analgetics retention–pharmacologic activity models using biopartitioning micellar chromatography

2002

Opioids are drugs used in medicine for pain control. In this paper, retention-pharmacokinetics and retention-pharmacodynamics relationships of opioids are proposed and statistically validated. These models are based on the compound retention in the biopartitioning micellar chromatography system (BMC), a new methodology which has successfully been used to develop QRAR models for many other families of compounds. The obtained results are compared to the traditional QSAR models using lipophilicity data. The adequacy of QRAR models is due to the fact that the characteristics of the compounds such as the hydrophobicity, electronic charge and steric effects determine both their retention in BMC a…
