The connection between uric acid (UA) and renal impairment is well known due to the urate capacity to precipitate within the tubules or extra-renal system. Emerging studies allege a new hypothesis ...concerning UA and renal impairment involving a pro-inflammatory status, endothelial dysfunction, and excessive activation of renin-angiotensin-aldosterone system (RAAS). Additionally, hyperuricemia associated with oxidative stress is incriminated in DNA damage, oxidations, inflammatory cytokine production, and even cell apoptosis. There is also increasing evidence regarding the association of hyperuricemia with chronic kidney disease (CKD), cardiovascular disease, and metabolic syndrome or diabetes mellitus.
Important aspects need to be clarified regarding hyperuricemia predisposition to oxidative stress and its effects in order to initiate the proper treatment to determine the optimal maintenance of UA level, improving patients' long-term prognosis and their quality of life.
Acute kidney injury (AKI) is one of the main conditions responsible for chronic kidney disease (CKD), including end-stage renal disease (ESRD) as a long-term complication. Besides short-term ...complications, such as electrolyte and acid-base disorders, fluid overload, bleeding complications or immune dysfunctions, AKI can develop chronic injuries and subsequent CKD through renal fibrosis pathways. Kidney fibrosis is a pathological process defined by excessive extracellular matrix (ECM) deposition, evidenced in chronic kidney injuries with maladaptive architecture restoration. So far, cited maladaptive kidney processes responsible for AKI to CKD transition were epithelial, endothelial, pericyte, macrophage and fibroblast transition to myofibroblasts. These are responsible for smooth muscle actin (SMA) synthesis and abnormal renal architecture. Recently, AKI progress to CKD or ESRD gained a lot of interest, with impressive progression in discovering the mechanisms involved in renal fibrosis, including cellular and molecular pathways. Risk factors mentioned in AKI progression to CKD are frequency and severity of kidney injury, chronic diseases such as uncontrolled hypertension, diabetes mellitus, obesity and unmodifiable risk factors (i.e., genetics, older age or gender). To provide a better understanding of AKI transition to CKD, we have selected relevant and updated information regarding the risk factors responsible for AKIs unfavorable long-term evolution and mechanisms incriminated in the progression to a chronic state, along with possible therapeutic approaches in preventing or delaying CKD from AKI.
Severe burn injuries lead to acute kidney injury (AKI) development, increasing the mortality risk up to 28–100%. In addition, there is an increase in hospitalization days and complications ...appearance. Various factors are responsible for acute or late AKI debut, like hypovolemia, important inflammatory response, excessive load of denatured proteins, sepsis, and severe organic dysfunction. The main measure to improve the prognosis of these patients is rapidly recognizing this condition and reversing the underlying events. For this reason, different renal biomarkers have been studied over the years for early identification of burn-induced AKI, like neutrophil gelatinase-associated lipocalin (NGAL), cystatin C, kidney injury molecule-1 (KIM-1), tissue inhibitor of metalloproteinase-2 (TIMP-2), interleukin-18 (IL-18), and insulin-like growth factor-binding protein 7 (IGFBP7). The fundamental purpose of these studies is to find a way to recognize and prevent acute renal injury progression early in order to decrease the risk of mortality and chronic kidney disease (CKD) onset.
Tenoxicam, a selective cyclooxygenase (COX)-2 inhibitor, has potent analgesic and anti-inflammatory effects and is frequently used for out-of-hospital pain control. Even though other non-steroidal ...anti-inflammatory drugs were incriminated in Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) appearance, the literature is scarce regarding this agent. We report a case of tenoxicam-induced toxic epidermal necrolysis, detailing the multidisciplinary approach in a patient presenting skin detachment of 90% of the total body surface area, with concomitant ocular, oral, nasal, and vaginal mucosae involvement. A skin biopsy confirmed the diagnosis. The immediate cessation of the incriminated drug and rapid initiation of systemic steroids, along with topical therapies, and isolation into a specific environmental condition to limit skin infection were the cornerstones of therapeutic management. The patient was discharged with skin hyperpigmentation area and mild anxiety as long-term sequels. This report emphasized that severe or complicated cases should be transferred to a specialized burn center to reduce mortality risk and long-term morbidity.
Non-syndromic toe syndactyly is a regular cause of foot malformation in children, bilateral form being less common. Syndactyly release procedures had few contraindications, as uncomplicated ...malformation or important patient comorbidities. Reported data show that corrective surgery using skin grafts is associated with an increased risk of infection, contractures, and web creep. Reconstruction surgical techniques, using flaps reduce morbidity, revision surgery, complication, may be associated with skin grafts and have superior aesthetic and functional results. We present a case of simple bilateral incomplete asymmetric toe syndactyly, released using a modified personalized local flaps reconstruction technique. The normal function and aesthetic of the feet was obtained, with no complications at one-year follow-up.
Burn injuries have a long-term negative impact on patients, families, and healthcare systems, and prevention remains the primary goal. Head and neck lesions have a reported prevalence between ...6-65.6%, sometimes even 95.1%. There are various risk factors and predictors of facial burns, like younger age, male sex, flame or flash burns, and work-related injuries. Surgical and non-surgical management is chosen depending on the burn type and extension, and the patients’ previous health status. Tangential necrosectomy is the gold standard of third-degree burn care. In the last years, enzymatic debridement showed promising results. Long-term complications, from altered sensibility, and face motor dysfunction, to hypertrophic scarring and mutilating aspects, frequently lead to depression, post-traumatic stress disorders, and social exclusion. To improve patients’ quality of life, various programs targeting reconstructive surgeries with cosmetic purposes, social skill training, and cognitive behavioral therapies should be implemented.
Burns represent one of the worldwide leading causes of injury. Burn wounds are associated with increased mortality and morbidity, especially the impaired quality of life due to hypertrophic scarring, ...scar pain and itching, paresthesia, and contractures. To properly influence the burn wound healing, it is important to establish a correct classification of the acute injury and to understand the main phase of burn wound healing process. There are various local and systemic factors that can be influenced to obtain proper healing. The most important factors include local necrosis and infection, increased local pressure and edema, anemia, hypoxia, hypotension, the presence of important chronic disease and medication, immunosuppression, nutritional status, age, and body constitution. After adequate fluid resuscitation and patient stabilization, the main step is represented by the detachment of the devitalized tissues and rapid coverage of the lesion. There are various methods to be used, like autologous or allogenic skin grafting, the use of skin substitutes, or tissue bioengineering. Knowing all these aspects, allows clinicians to properly define a therapeutic management for patients presenting severe burns.
Upper extremities are frequently involved in fire burns due to the natural protective reflexes. The presence of bilateral Dupuytrenʼs disease and COVID-19 disease in patients with circumferential ...upper extremity burns can negatively impact the outcome, through severe contracture and a tendency to hypoxia or infections, which affects normal wound healing. Enzymatic debridement with a concentrate of proteolytic enzymes enriched in bromelain prevents compartment syndrome development in such patients, reduces blood loss, surgery duration, and appears to favor a more rapid recovery.
Pain control is crucial in surgical patients, being an essential part of enhanced recovery after surgery protocols. Lidocaine, an amide local anesthetic, was primarily used as an antiarrhythmic. It ...has analgesic, antihyperalgesic and anti-inflammatory effects, with various actions on cardiovascular, respiratory, and digestive systems. Lidocaine has been shown to also have antithrombotic, antimicrobial, and antitumoral effects. Numerous studies have reported its safe profile and role in managing perioperative pain after breast cancer, abdominal, genitourinary, gynecologic, obstetric, orthopedic, cardiothoracic, spine, thyroid, and upper airway surgery. Lidocaine, as part of multimodal analgesia, also shows promising results in ambulatory surgery. Therefore, the use of intravenous lidocaine in the perioperative period is mainly associated with better pain control, reduced opioid use, diminished incidence of postoperative nausea, vomiting, and ileus, and exhibits antithrombotic effects.
Chronic kidney disease (CKD) is associated with different complications, including chronic kidney disease-mineral and bone disorder (CKD-MBD), which represents a systemic disorder that involves the ...presence of different mineral or bone structure abnormalities (i.e., modification of bone turnover, strength, volume, etc.), including even vascular calcification development. Even if, over the years, different pathophysiological theories have been developed to explain the onset and progression of CKD-MBD, the influence and importance of serum magnesium level on the evolution of CKD have only recently been highlighted. So far, data are inconclusive and conflicting; therefore, further studies are necessary to validate these findings, which could be useful in developing a better, more adequate, and personalized management of CKD patients.
