Digital Ischaemia

Abstract. The primary goal of therapy is to reduce the frequency and intensity of Raynaud’s attacks and to minimize the related morbidity rather than to cure the underlying condition. Treatment strategies depend on whether Raynaud’s phenomenon (RP) is primary or secondary. All patients should be instructed about general measures to maintain body warmth and to avoid triggers of RP attacks. Pharmacologic intervention can be useful for patients with severe and frequent RP episodes that impair the patient’s quality of life. Calcium channel blockers are currently the most prescribed and studied medications for this purpose. There has been limited evidence for the efficacy of alpha-1-adrenergic receptor antagonists, angiotensin receptor blockers, topical nitrates or fluoxetine to treat RP. The intravenously administered prostacyclin analogue iloprost can reduce the frequency and severity of RP attacks and is considered a second-line therapy in patients with markedly impaired quality of life, critical digital ischaemia and skin ulcers who are at risk for substantial tissue loss and amputation. Phosphodiesterase inhibitors (e.g., sildenafil) can also improve RP symptoms and ulcer healing whereas endothelin-1 receptor antagonists (e.g., bosentan) are mainly considered treatment options in secondary prevention for patients with digital skin ulcers related to systemic sclerosis. However, their use in clinical practice has been limited by their high cost. Antiplatelet therapy with low-dose aspirin is recommended for all patients who suffer from secondary RP due to ischaemia caused by structural vessel damage. Anticoagulant therapy can be considered during the acute phase of digital ischaemia in patients with suspected vascular occlusive disease attributed to the occurrence of new thromboses. In patients with critical digital ischaemia, consideration should be given to hospitalisation, optimisation of medical treatment in accordance with the underlying disease and evaluation for a secondary, possibly reversible process that is causing or aggravating the clinical symptoms.

Background: Reducing the healing time of wounds can decrease the patient`s immobility time and their medical costs,leading a faster return of the patients to daily work. Objective: To compare the effect of adipose-derived stem cells and curcumin-containing liposomal nanoparticles with phenytoin on wound healing. Method: After anesthesia of the rats, open skin ulcers were made by a bistoury blade.Subsequently,stem cells were re-moved from the adipose tissue of theupper border of the epididymis. Then,the originality of stem cells was confirmed by the flow cytometry. The fusion method was used to prepare the liposome;and also nanoliposomal particles wereconfirmedby using the DLS microscope.The percentage of recovery and the cell count was measured with IMAGEJ.The expression of genes was assessed by PCR. The number of fibro blasts was counted by immuno histo chemistry techniques.The amount of collagen was determined by Tri-chromosome staining and the number of capillaries was enumerated byH & E staining. Results: The expression of TGF-β1 gene, vascular number, wound healing rate and the numberof fibroblasts increased significantly in adipose tissue-derived stem cells and curcumin nanoliposome groups(p<0.05);the wound surface was also decreased significantly(p<0.05). Conclusion: Based on the results of our research, adipose tissue-derived stem cells and curcumin nanoliposomescan heal wounds efficiently.

Abstract Background Ecthyma gangrenosum (EG) is a cutaneous infectious disease characterized by eschar-like skin ulcers typically caused by Pseudomonas aeruginosa. Here, we report a case of relapsing EG in a patient who had returned from a trip to Colombia, thus establishing EG as an important differential diagnosis of tropical diseases, and demonstrating that even long-term antibiotic treatment can result in only partial remission of EG. Case presentation A 77-year-old man with underlying chronic lymphocytic leukemia (CLL) on ibrutinib treatment was admitted because of a superinfected mosquito bite on the left ear and multiple partially necrotic skin lesions disseminated all over the entire body five days after returning from a trip to Colombia. The initial clinical suspicion of a tropical disease (leishmaniosis, systemic mycosis, or others) could not be confirmed. During the diagnostic workup, microbiological cultures of the skin biopsies and bronchoalveolar lavage revealed Pseudomonas aeruginosa, leading to a diagnosis of EG. Initial antibiotic treatment resulted in partial remission. However, the patient had to be re-admitted due to a relapse 3–4 weeks after the first episode. Finally, the patient was successfully treated with a combined approach consisting of antibiotics, recurrent surgical incisions, and administration of immunoglobulins. Conclusions In conclusion, EG should be considered as a differential diagnosis in immunosuppressed patients presenting with eschar-like skin ulcers. A combined treatment approach seems to be the best choice to achieve clinical cure and avoid relapse.
