Although wound healing is probably the most critical aspect of essential medical and surgical care, it has been neglected for a long time. With the tremendous surge over the last two decades in basic research, wound healing is emerging as a well‐defined medical entity transcending existing specialties and subdivisions. In view of the multitude of health professionals interested in the field of wounds and wound healing, it seems reasonably warranted to group them under one and single appellation. We suggest ‘vulnerology’ as a new term to describe the discipline of wound care. 相似文献

Sarcoidosis is thought to result from the interaction between an unknown environmental antigenic trigger and the host's genetic susceptibility. We hypothesized that sarcoidosis, or one of the disease subsets, could be associated with single nucleotide polymorphisms of C-C chemokine receptor 2 (CCR2) gene. Eight single-nucleotide polymorphisms in CCR2 were studied in a total of 304 Dutch individuals (90 non-L?fgren sarcoidosis, 47 L?fgren's syndrome, 167 control subjects). From the investigated CCR2 polymorphisms, nine haplotypes were deduced (haplotypes 1-9). In patients with L?fgren's syndrome, a strongly significant increase in the frequency of CCR2-haplotype 2, which includes four unique alleles (A at nucleotide position -6752, A at 3,000, T at 3,547, and T at 4,385), was observed compared with control subjects (74% vs. 38% respectively, p < 0.0001), whereas no difference was found between non-L?fgren sarcoidosis and control subjects (both 38%). The association between CCR2-haplotype 2 carriage frequency and L?fgren's syndrome (odds ratio, 4.4; p < 0.0001) remained significant after adjustment for human leukocyte antigen haplotype DRB1*0301-DQB1*0201 (odds ratio, 11.5; p < 0.0001) and female sex (odds ratio, 3.2; p = 0.003), two known risk factors for L?fgren's syndrome. In conclusion, this report describes a strong association between CCR2-haplotype 2 and L?fgren's syndrome. Further studies are needed to understand the molecular mechanisms underlying this association. 相似文献

Noma neonatorum should be differentiated from noma, in that it is typically a disease of seriously ill premature infants whose birth weight was low, and is caused by Pseudomonas aerugenosa septicaemia. We know of only two case reports of noma neonatorum involving newborn infants born at full term, so we report here another case of noma neonatorum in a neonate born at full term. In addition we describe the differences between noma neonatorum and noma (cancrum oris), a clinically related entity. 相似文献

The relationship between first postoperative day epithelial status and eventual health of the ocular surface in penetrating keratoplasty 总被引:1,自引:0,他引:1
PURPOSE: To determine a possible relationship between donor epithelial status on the first postoperative day after keratoplasty and the eventual health of the corneal surface. METHODS: We analyzed 91 patients who underwent penetrating corneal transplantation between January 1998 and January 2000, monitoring the epithelial status of the corneas with fluorescein staining using slit-lamp biomicroscopy. Recipient pre- and postoperative variables and donor characteristics were recorded. Macroepithelial defects were classified into three groups according to the extent of the epithelial defect. The results on the first postoperative day were compared with the first and third operative month. Donor and recipient variables were compared with the epithelial status on the first and third month as well. RESULTS: On the first postoperative day, 64.84% of the patients had epithelial defects, 10.99% had defects at the 1-month postoperative visit, and none had defects at the third month. Graft recipients with macroepithelial defects in the first postoperative month were older, had a higher prevalence of blepharitis, higher prevalence of inadequate eye hydration, and slightly increased corneal sensation compared with the group without epithelial defects; however, none of these trends were statistically significant. Patients with macroepithelial defects in the first postoperative month received older donor tissue, and the average preservation-to-surgery time was longer. These donor variables, however, were not significant statistically (p value >0.10) in determining outcome of the epithelial status at the first or third months. CONCLUSIONS: Our results suggest that the epithelial status on the first postoperative day is not predictive of surface integrity at 1-month postoperative (p value is 0.2676 for the likehood ratio test). The epithelial status on the first postoperative day is not predictive of the status of the third month after keratoplasty, because none of the 91 patients had epithelial defects after 3 months. 相似文献

The history of wound care and management closely parallels that of military surgery which has laid down the principles and dictated the practices of wound cleansing, debridement and coverage. From a treatment standpoint, there are essentially two types of wounds: those characterized by loss of tissue and those in which no tissue has been lost. In the event of tissue loss it is critical to determine whether vital structures such as bone, tendons, nerves and vessels have been exposed. It is also important to determine the amount of soft tissue contusion and contamination. In any case primary wound healing by early closure either primarily or with the help of grafts or flaps is preferred to secondary healing and wound contraction with subsequent contractures which interfere with range of motion and function. Whether the wound is acute or chronic, essential principles of wound care must be observed in order to avoid wound sepsis and achieve rapid and optimal wound healing. - Tissues must be handled gently. - Caustic solutions capable of sterilizing the skin should never be applied to the wound. It is desirable never to put anything in the wound that cannot be tolerated comfortably in the conjunctival sac. - All devitalized tissues must be debrided either hydrodynamically, chemically, mechanically or surgically. - All dead space must be obliterated. - Exposed vital structures must be covered by well vascularized tissues. An essential part of any wound management protocol is wound dressing. It cannot be too strongly emphasized that a wound dressing may have a profound influence on healing particularly of secondary type healing, a critical feature being the extent to which such dressing restricts the evaporation of water from the wound surface. A review of available dressing materials is reported with emphasis on the newly developed concept of moist environment for optimal healing. a practical guide for dressing selection is also proposed. 相似文献

Keloid and hypertrophic scars are 2 types of excessive scarring observed clinically that require different therapeutic approaches. The clinical course and physical appearance define keloids and hypertrophic scars as separate entities; however, they are often confused because of an apparent lack of morphologic differences. Nevertheless, clinical differences between hypertrophic scars and keloids have long been recognized by plastic surgeons and dermatologists. Yet, translating these differences into morphologic or biochemical distinctions has prompted much conflict in the literature. The present report is an attempt to clarify the longstanding controversy regarding these 2 similar yet separate and nonidentical entities by highlighting the reported points of differentiation as well as the similarities. 相似文献
