OBJECTIVE: Pain in chronic venous ulcers (CVUs) notably increases with the usual cleaning of the wound. Chronic pain is usually poorly controlled even with the multiple analgesic treatments available. Analgesics can have different serious adverse effects and medical interactions in old patients with several comorbidities. This study reports the efficacy and safety of topical sevoflurane for treatment of pain in CVUs. METHODS: We report a descriptive and retrospective study of 30 patients older than 65 years with painful CVUs refractory to conventional analgesic treatments...

PURPOSE: Recent controversies on the safety profiles of opioids and paracetamol (acetaminophen) have led to changes in clinical guidance on osteoarthritis (OA) management. We studied the existing association between the use of different OA drug therapies and the risk for acute coronary events. METHODS: A cohort of patients with clinically diagnosed OA (according to ICD-10 codes) was identified in the SIDIAP database. Within the cohort, cases with incident acute coronary events (acute myocardial infarction or unstable angina) between 2008 and 2012 were identified using ICD-10 codes and data from hospital admission...

Pharmaceutical manufacturers have to study the stability of drug products before marketing according to ICH guideline Q1A(R2); data of those investigations aim to set expiry dates. The expiry date on the container of a remedy assures the physician and the patient a stability of the drug in its formulation i.e. within a specification of 95-105%. Only few studies show that shelf-lives of pharmaceutical products are often longer than expiration dates. The objective of the study presented here was determining the content of nine expired ampoules manufactured in the last century and identifying the impurity profile by means of HPLC-UV and HPLC-MS, respectively...

Non-chemotherapy idiosyncratic drug-induced neutropenia (IDIN) is a relatively rare but potentially fatal disorder that occurs in susceptible individuals, with an incidence of 2.4 to 15.4 cases per million population. Affected patients typically experience severe neutropenia within several weeks to several months after first exposure to a drug, and mortality is ∼5%. The drugs most frequently associated with IDIN include metamizole, clozapine, sulfasalazine, thiamazole, carbimazole, amoxicillin, cotrimoxazole, ticlopidine, and valganciclovir...

BACKGROUND: Adenocarcinoma of the pancreas is one of the most aggressive cancer diseases affecting the human body. Recent research has shown the importance of the perioperative phase in disease progression. Particularly during this vulnerable phase, substances such as metamizole and paracetamol are given as general anesthetics and postoperative analgesics. Therefore, the effects of metamizole and paracetamol on tumor progression should be investigated in more detail because the extent to which these substances influence the carcinogenesis of pancreatic carcinoma is still unclear...

In forensic medicine, expert opinion is often required concerning dose and time of intake of a substance, especially in the context of fatal intoxications. In the present case, a 98-year-old man died 4 days after admission to a hospital due to a femur neck fracture following a domestic fall in his retirement home. As he had obtained high morphine doses in the context of palliative therapy and a confusion of his supplemental magnesium tablets with a diuretic by the care retirement home was suspected by the relatives, a comprehensive postmortem examination was performed...

Dipyrone has analgesic, spasmolytic, and antipyretic effects and is used to treat pain. Due to a possible risk of agranulocytosis with the use of dipyrone, it has been banned in a number of countries. The most commonly used data for the use of dipyrone are related to adults. Information relating to the use of dipyrone in children is scarce. Given the potential added value of dipyrone in the treatment of pain, a review of the literature was conducted to obtain more insight into the analgesic efficacy of dipyrone in children as well as the safety of dipyrone in terms of adverse events...
