Then, in the Gospel, we see a crew of fishermen marveling at a miraculous catch of fish orchestrated by Jesus. “Here I am,” he tells the Lord, “send me!” Yet God (through his angel) intervenes, the imperfections are addressed, and the prophet steps up to his heavenly commission. He was “a man of unclean lips, living among a people of unclean lips.” Seriously scarred, in other words. In contrast, Isaiah was plagued by his inadequacy. The first reading had Isaiah cowering before the majesty and glory of the Lord, and overawed by the angelic beings proclaiming their praise.
It was last Sunday’s Mass readings that got me thinking about incisions, wounds, and lingering scars. It takes longer, it’s unsightly, and it results in an area considerably weaker compared to the surrounding skin. Since the gap is so large, there’s no mechanism for healthy tissue to fill the void, so the body substitutes scar tissue instead.
The edges can be jagged and hard to bring together, and they may be left open to allow nature to take its course - which is healing by second intention. Other wounds, however, are not so tidy - like extensive traumatic injuries and bad bedsores. Healing by first intention is usually relatively rapid and thorough, with minimal scarring and limited loss of tissue integrity. The cut is bound together by sutures or the like, and so there’s direct communication between the separated sides as the tissue re-building commences. Some wounds are clean and even – like the incisions that surgeons make – and so they heal by what clinicians call first intention. It’s the same process, more or less, for all kinds of tissue disruption beyond the most superficial ones, although the results vary widely depending on a variety of factors.Ĭhief among these, perhaps, is how clean the original wound was and how closely its edges can be brought together in order to facilitate the repair. Part of our classroom time was spent talking about the wound healing process - from inflammatory response and new tissue proliferation to maturation, remodeling, and restoration of function. So, surgery generally involves some kind of incision, some kind of wound.

It requires getting past the superficial layers of our skin in order to manipulate, remove, and/or introduce structures underneath. One of the most important of these is monitoring surgical incisions for signs of infection and other problems.īy definition, surgery is invasive.

This review summarizes and compares all available diagnostics for wound infection, including those currently used in clinics and still under development. Products may be developed to either qualitatively or quantitatively measure these biomarkers. Future Directions: While innovative diagnostics utilizing various imaging instrumentation are being developed, new biomarkers have been investigated as potential indicators for wound infection. There is a need for noninvasive wound infection diagnostics that are highly specific, rapid, and accurate, and do not require extensive training. Critical Issues: While traditional diagnostic approaches provide valuable information, they are time-consuming and depend on clinicians' experiences. Moreover, imaging modalities like plain radiography, computed tomography, magnetic resonance imaging, ultrasound imaging, spatial frequency domain imaging, thermography, autofluorescence imaging, and biosensors have emerged for real-time wound infection diagnosis and showed their unique advantages in deeper wound infection diagnosis. Many laboratory markers, including C-reactive protein, procalcitonin, presepsin, and bacterial protease activity, have been quantified to assist diagnosis of infection.
Recent Advances: Traditionally, clinicians determine the presence of infection through visual observation of wounds and confirm their diagnosis through wound culture. Identification of infection biomarkers and imaging modalities to observe and quantify them has seen progress over the years. Significance: Infections can significantly delay the healing process in chronic wounds, placing an enormous economic burden on health care resources.
