Natural Products in the Treatment of Unremitting Wounds Secondary to Diabetes or Peripheral Vascular Disease
Published in Namrita Lall, Medicinal Plants for Cosmetics, Health and Diseases, 2022
There is a wide variety of antimicrobial dressings commercially available. Antimicrobial topical wound dressings may contain silver, iodine or a variety of synthetic compounds. Antimicrobial dressings are used when wounds are thought to be critically colonized or infected, inhibiting normal wound healing progression. However, additional randomized controlled trials are needed to determine the true effectiveness of antimicrobial dressings in patients with DFUs (Dumville et al., 2017).
Criticism of allopathy
Published in Dinesh Kumar Jain, Homeopathy, 2022
Hahnemann writes, “Use of calomel, corrosive sublimate, mercurial ointment, nitrate of silver, iodine ointment, opium, valerian, cinchona bark and quinine, foxglove, prussic acid, sulfur and sulfuric acid, venesections, shedding streams of blood, leeches is dangerous to human body” (Hahnemann, 1921/1993, p. 162). These drugs and treatments were used by old allopathy. At present, in modern medical science, these treatments are not used systemically. Locally some compounds are used. Criticism of this treatment by Hahnemann is correct. But present medical science or present allopathy does not permit the use of these treatments. Only quinine and iodine are used systemically in malaria and hypothyroidism, respectively. Modern medical science uses iodine or quinine only after extensive study of 5–10 years on these compounds.
Scintillation Fiber Optic Dosimetry
Published in Arash Darafsheh, Radiation Therapy Dosimetry: A Practical Handbook, 2021
HWGs are generally used for infrared laser power delivery due to their air core. The development of waveguides with hollow cores was a milestone in infrared light transmission, where conventional solid-core fibers dramatically suffer from optical power loss. HWGs structurally are composed of a glass or plastic capillary coated internally with a metal/dielectric layer to enhance the infrared transmission in the waveguide. The structure of a typical HWG is shown in Figure 9.2. A metallic layer of silver (∼0.5–2 μm thick) is coated on the inside of the silica tubing and then a dielectric layer of silver iodide is formed over the metal film through an iodization process in which some of the Ag is converted to AgI [33]. The silica tubing has a polymer coating on its outside surface. Since HWGs are typically designed for infrared light transmission, their transmission in visible range is suboptimal. However, it has been shown that silver-only coated HWGs, i.e., without the dielectric silver iodide layer, have superior transmission in visible range of the spectrum compared with the conventional HWGs with silver/dielectric coating that are optimized for transmission of infrared light. Attenuation in visible spectral region ∼0.7 dB/m (∼85% transmission after 1 m) has been reported for such HWGs [34]. For visible light transmission, solid-core fibers are preferred over HWGs.

Application of SDF is simple and uncomplicated compared to other operative treatment options and can be performed anywhere without advanced equipment. Isolation of actual lesion is easily handled, and application with micro brush before immediate blot drying suffice. Low treatment cost per application may make SDF application a cost effective treatment for caries arrest [16]. The major criticism against SDF is discoloration of caries lesions into brown/black appearance. When applying potassium iodide (KI) immediately on wet SDF, a white silver-iodide precipitate is created. This largely prevents the discoloration to begin with, but arrested carious lesions have a tendency to darken by time anyway [11].

Gauze, soft polymer, alginate, silver, iodine, honey, hydrocolloid, hydrogel, foam, and transparent film are the most common dressings used for the PU in different stages.27–44 None has been proved to be superior to others in the literature.29
