Lidocaine 700 mg medicated plaster for post-herpetic neuralgia: focus on Quality of Life, effectiveness and safety - a retrospective observational study.

OBJECTIVE: Postherpetic neuralgia (PHN) is a neuropathic pain syndrome following herpes zoster (HZ) infection, characterized by pain that persists for months to years after the resolution of the HZ rash. Therapeutic management remains challenging for every clinician. We report the follow-up of patients diagnosed with PHN and treated with lidocaine 700 mg medicated plaster (LMP), focusing on effectiveness, safety, and Quality of Life (QoL). MATERIALS AND METHODS: This study is a retrospective observational investigation of patients with PHN treated with LMP. Patients were regularly followed for pain intensity, co-analgesic consumption, adverse effects, QoL using the EQ-5D, and patient satisfaction for 8 weeks. RESULTS: A total of 31 patients were evaluated. At enrollment, 18 patients (58.1%) were treated with at least one PHN concomitant medication, for which the number and dosing remained constant during the study. Patients had a mean average pain intensity of 6.5±1.0 at baseline, which decreased to 3.6±1.1 at week 4 and 2.8±0.9 at week 8. Four patients reported erythema, and one complained of vesicles eruption associated with pruritus. EQ-5D at weeks 4 and 8 of treatment showed persisting improvements in all domains except for the "anxiety/depression" domain. At week 8, <80% of patients reported to be satisfied or very satisfied. CONCLUSIONS: This study adds further weight to the growing body of clinical and research evidence that LMP treatment is effective and well-tolerated in patients with PHN.

Septic shock due to Escherichia coli meningoencephalitis treated with immunoglobulin-M-enriched immunoglobulin preparation as adjuvant therapy: a case report.

BACKGROUND: Gram-negative bacteria are an uncommon etiology of spontaneous community-acquired adult meningitis and meningoencephalitis. Escherichia coli is a Gram-negative bacterium that is normally present in the intestinal microbial pool. Some Escherichia coli strains can cause diseases in humans and animals, with both intestinal and extraintestinal manifestations (extraintestinal pathogenic Escherichia coli) such as urinary tract infections, bacteremia with sepsis, and, more rarely, meningitis. Meningitis continues to be an important cause of mortality throughout the world, despite progress in antimicrobial chemotherapy and supportive therapy. The mortality rate fluctuates between 15% and 40%, and about 50% of the survivors report neurological sequelae. The majority of Escherichia coli meningitis cases develop as a result of hematogenous spread, with higher degrees of bacteremia also being related to worse prognosis. Cases presenting with impaired consciousness (that is, coma) are also reported to have poorer outcomes. CASE PRESENTATION: We describe the case of a 48-year-old caucasian woman with meningoencephalitis, with a marked alteration of consciousness on admission, and septic shock secondary to pyelonephritis caused by Escherichia coli, treated with targeted antimicrobial therapy and immunoglobulin-M-enriched immunoglobulin (Pentaglobin) preparation as adjuvant therapy. CONCLUSION: Despite the dramatic presentation of the patient on admission, the conflicting data on the use of immunoglobulins in septic shock, and the lack of evidence regarding their use in adult Escherichia coli meningoencephalitis, we obtained a remarkable improvement of her clinical condition, accompanied by partial resolution of her neurological deficits.

Continuous intravenous low-dose diclofenac sodium to control a central fever after ischemic stroke in the intensive care unit: a case report and review of the literature.

INTRODUCTION: Elevation in body temperature within the first 24 hours of ischemic stroke is fairly common and known to be associated with worse outcomes. Only after thoroughly ruling out infection and the noninfectious etiologies and in the appropriate clinical setting should the diagnosis of central fever be made. Acetaminophen and nonsteroidal anti-inflammatory drugs are typical therapeutic options. External cooling is frequently used when pharmacologic interventions are inadequate. However, reports have suggested that neurogenic fevers are somewhat resistant to traditional pharmacologic therapies. CASE PRESENTATION: We describe a case of a Caucasian patient with central fever after ischemic stroke not responsive to acetaminophen administration and external cooling. After an initial bolus of diclofenac sodium (0.2 mg/kg in 100 ml of saline solution for 30 minutes), a continuous infusion (75 mg in 50 ml of saline solution) was started. After 5 days of treatment, the patient's body temperature was below 37.5 °C, and the diclofenac sodium infusion was stopped. CONCLUSIONS: We observed that a low-dose diclofenac sodium infusion was effective in treating fever without systemic side effects. This treatment may be suggested as an alternative to conventional antipyretic drugs, but additional clinical trials are required.

Opioids switching with transdermal systems in chronic cancer pain.

BACKGROUND: Due to tolerance development and adverse side effects, chronic pain patients frequently need to be switched to alternative opioid therapy OBJECTIVE: To assess the efficacy and tolerability of an alternative transdermally applied (TDS) opioid in patients with chronic cancer pain receiving insufficient analgesia using their present treatment. METHODS: A total of 32 patients received alternative opioid therapy, 16 were switched from buprenorphine to fentanyl and 16 were switched from fentanyl to buprenorphine. The dosage used was 50% of that indicated in equipotency conversion tables. Pain relief was assessed at weekly intervals for the next 3 weeks RESULTS: Pain relief as assessed by VAS, PPI, and PRI significantly improved (p < 0.0001) in all patients at all 3 follow up visits. After 3 weeks of treatment, the reduction in the mean VAS, PPI, and PRI scores in the fentanyl and buprenorphine groups was 68, 77, 74, and 69, 79, and 62%, respectively. Over the same time period the use of oral morphine as rescue medication was reduced from 27.5 +/- 20.5 (mean +/- SD) to 3.75 +/- 8.06, and 33.8 +/- 18.9 to 3.75 +/- 10.9 mg/day in the fentanyl and buprenorphine groups, respectively. There was no significant difference in either pain relief or rescue medication use between the two patient groups The number of patient with adverse events fell during the study. After the third week of the treatment the number of patients with constipation was reduced from 11 to 5, and 10 to 4 patients in the fentanyl and buprenorphine groups, respectively. There was a similar reduction in the incidence of nausea and vomiting. No sedation was seen in any patient after one week of treatment. CONCLUSION: Opioid switching at 50% of the calculated equianalgesic dose produced a significant reduction in pain levels and rescue medication. The incidence of side effects decreased and no new side effects were noted. Further studies are required to provide individualized treatment for patients according to their different types of cancer.
