Chemical burns constitute approximately 10.7% of all burn cases and 2.2% of all major burn cases in Taiwan. Furthermore, they have been estimated to cause 30% of all burn-related deaths. The burn depth can often be difficult to assess, as burns that appear superficial might be associated with severe deep tissue injuries. Consequently, the extent of injury is often underestimated, leading to insufficient irrigation. Wound healing after a chemical burn is considerably slower than that after a similarly sized thermal burn; therefore, patients often require extended hospital treatment. The potency and concentration of the chemical agent and the duration of contact primarily determine the degree of tissue destruction. The most crucial part in managing chemical burns is thorough irrigation of all wounds and areas of exposure with high amounts of sterile saline. There are a few exceptions to this approach; for example, burns caused by dry lime, phenols, concentrated hydrochloric acid, sulfuric acid, and elemental metals should not be irrigated immediately because irrigation can cause a harmful exothermic reaction and release hazardous by-products. Relevant evidence for guiding management methods and determining the duration of irrigation is lacking. Usually, continuous irrigation is required until the pH of any exposed tissue becomes neutral; this might require hours and several liters of saline. The same approach applies to alkaline burns; however, a considerably longer period of irrigation is necessary. There are six mechanisms of action for chemical agents in biological systems, namely, oxidation, reduction, corrosion, protoplasmic poisons, vesicants, and desiccants. Sulfuric buy Solamargine is one of the agents most often involved in acid burns and may cause injury through dehydration damage and excessive heat in tissue. The chemical burn produces coagulation and necrotic eschars with thrombus formation in the local tissue microvasculature.
Conclusion
Introduction Klippel–Trénaunay syndrome (KTS) is a rare congenital disorder that was first described in 1900 by French physicians Maurice Klippel and Paul Trénaunay. The disease is characterized by mixed vascular anomalies composed of lymphatic, capillary, and venous malformations. Klippel–Trénaunay syndrome differs from Parkes Weber syndrome in that it does not entail substantial arteriovenous shunting. The classic triad features of KTS are the following: (1) port-wine stains (i.e., capillary malformations); (2) soft tissue and bone hypertrophy on association with lymphatic malformations; and (3) abnormal varicosities (i.e., venous malformations). The management of KTS is difficult because of its progressive nature and wide range of disease severity. Treatment requires a multimodal approach comprising conservative therapy, sclerotherapy, laser therapy, and surgery. Each of these approaches has a specific role in the management of various disease components. Performing surgery is controversial, although resection and stripping of engorged veins may be considered for patients with prominent and painful varicosities. Partial excision of the malformed tissue can be performed in certain patients. In this paper, we report two patients with pediatric lower limb KTS in whom tissue expanders were initially applied, followed by partial excisional surgery. Adequate tissue expansions were achieved and facilitated immediate reconstruction of the skin and soft tissue around the knee joint.
Case reports
Discussion Klippel–Trénaunay syndrome occurs in all ethnic groups with an equal frequency wordwide. There are no known direct hereditary factors and its etiology remains unclear. Unilateral lower limbs are predominantly affected. Most patients exhibit the classical triad: (1) port-wine stains, (2) soft tissue and bone hypertrophy, and (3) abnormal varicosities. A definitive diagnosis can be made based on identifying two of the three aforementioned features. In most patients, at least one abnormal finding is noted shortly after birth, whereas the remaining features usually become evident as the child ages. To further investigate KTS, MRI, a noninvasive and nonionizing tool, is typically performed to provide detailed multiplanar images of soft tissue in the affected area. The depth and extent of the malformed tissues and its relationship with the surrounding structures can be clearly illustrated. For all our KTS patients, MRI is the standard imaging tool used to assess the extent of the disease and to conduct preoperative planning.
