To analyze the efficacy and safety of duloxetine and gabapentin in painful diabetic neuropathy (PDN).

A randomized, open-label, active control, 12-week trial was conducted. A total of 86 participants were randomized in 11 ratio into gabapentin 300 mg and duloxetine 60 mg groups. The primary efficacy objective was comparison of mean change in Visual Analogue Scale (VAS) (0-100 points) scores between duloxetine and gabapentin. The symptom scores and adverse events were assessed as secondary outcomes.

Statistically significant (P value<.001) improvement was observed in VAS scores in both duloxetine group and gabapentin group at 12 weeks as compared to baseline. However, no significant difference in VAS scores between duloxetine and gabapentin. Similar improvement in diabetic neuropathy symptoms (DNS), diabetic neuropathy examination (DNE), and neuropathic disability score (NDS) was observed in either group over 12 weeks. There were no significant differences in DNS (P = 0.578), DNE (P = 0.410), and NDS (P = 0.071) scores between the two treatment groups. The overall safety evaluation of both duloxetine and gabapentin were similar. selleck inhibitor The most common adverse events reported were gastrointestinal.

The results indicated that both drugs were effective for the symptomatic relief from PDN and had similar efficacy. Follow-up of patients was only for 12 weeks and therefore the long-term efficacy and safety of the study drugs could not be assessed.

Modulation of macrophage polarization with interleukin-4 (IL-4) has emerged as an effective means to limit wear particle-induced osteolysis. The aim of this study was to evaluate the efficacy of local IL-4 delivery in treating preexisting particle-induced osteolysis. To this end, recently established 8 week modification of murine continuous femoral intramedullary particle infusion model was utilized. Subcutaneous infusion pumps were used to deliver polyethylene (PE) particles into mouse distal femur for 4 weeks to induce osteolysis. IL-4 was then added to the particle infusion for another 4 weeks. This delayed IL-4 treatment (IL-4 Del) was compared to IL-4 delivered continuously (IL-4 Cont) with PE particles from the beginning and to the infusion of particles alone for 8 weeks. Both IL-4 treatments were highly effective in preventing and repairing preexisting particle-induced bone loss as assessed by μCT. Immunofluorescence indicated a significant reduction in the number of F4/80 + iNOS + M1 macrophages and increase in the number of F4/80 + CD206 + M2 macrophages with both IL-4 treatments. Reduction in the number of tartrate resistant acid phosphatase + osteoclasts and increase in the amount of alkaline phosphatase (ALP) + osteoblasts was also observed with both IL-4 treatments likely explaining the regeneration of bone in these samples. Interesting, slightly more bone formation and ALP + osteoblasts were seen in the IL-4 Del group than in the IL-4 Cont group although these differences were not statistically significant. The study is a proof of principle that osteolytic lesions can be repaired via modulation of macrophage polarization.

Microneedling devices are being used as a surgical technique without a clear regulatory category. They can become dangerous considering that these kind of devices can easily be bought and used by nonqualified people.

Our aim has been to demonstrate that microneedling devices used in dermatological surgery are Medical Devices according to the current regulations.

After a thorough review in the European Union and USA medical device classification, we consider microneedling systems as Class II (US) or IIa (EU).

Therefore, they must follow the regulations established for medical devices. A risk assessment has also been made, in which the technical and scientific deficiencies in their design and manufacturing have been recognized in addition to including compulsory information for the regulatory agencies and most importantly for the final user.

It can be concluded that microneedling is an interesting tool in dermatology although more information related to its safety needs to be submitted. In addition, its use by nonprofessional people does not guarantee the safety of the user.

The prevention and treatment of CIPN are limited by a lack of understanding of the molecular mechanisms underlying this toxicity. In the current study, a human induced pluripotent stem cell-derived sensory neuron (iPSC-SN) model was developed for the study of chemotherapy-induced neurotoxicity. The iPSC-SNs express proteins characteristic of nociceptor, mechanoreceptor, and proprioceptor sensory neurons and show Ca2+ influx in response to capsaicin, α,β-meATP, and glutamate. The iPSC-SNs are relatively resistant to the cytotoxic effects of paclitaxel, with half-maximal inhibitory concentration (IC50 ) values of 38.1 µM (95% confidence interval (CI) 22.9-70.9 µM) for 48-hour exposure and 9.3 µM (95% CI 5.7-16.5 µM) for 72-hour treatment. Paclitaxel causes dose-dependent and time-dependent changes in neurite network complexity detected by βIII-tubulin staining and high content imaging. The IC50 for paclitaxel reduction of neurite area was 1.4 µM (95% CI 0.3-16.9 µM) for 48-hour exposure and 0.6 µM (95% CI 0.09-9.9 µM) for 72-hour exposure. Decreased mitochondrial membrane potential, slower movement of mitochondria down the neurites, and changes in glutamate-induced neuronal excitability were also observed with paclitaxel exposure. The iPSC-SNs were also sensitive to docetaxel, vincristine, and bortezomib. Collectively, these data support the use of iPSC-SNs for detailed mechanistic investigations of genes and pathways implicated in chemotherapy-induced neurotoxicity and the identification of novel therapeutic approaches for its prevention and treatment.
