Successful management of rhabdomyolysis with acute infection resulting from chronic sacrococcygeal pressure ulcers in a paraplegic patient: a case report

Rhabdomyolysis, a potentially life-threatening syndrome, is caused by the breakdown of skeletal muscle cells and leakage of intramyocellular contents into the bloodstream. The treatment of rhabdomyolysis resulting from chronic sacrococcygeal pressure ulcers has been rarely reported. A 62-year-old man developed a high fever and dark-colored urine. For the past 30 years, he had lived with paraplegia, which led to his immobility. Physical examination showed evidence of repeated dehiscence and exudation of the wound on his sacrococcygeal region with loss of skin sensation. Upon corroboration of the physical examination findings and laboratory test results, the patient was diagnosed with rhabdomyolysis with an acute infection resulting from sacrococcygeal pressure ulcers. We first debrided the necrotic tissue and then repaired the chronic ulcer. The wound dressing was changed frequently, and antimicrobial therapy and nutritional support were included in the treatment. The fever and dark-colored urine gradually resolved postoperatively. The patient’s renal function also improved according to the typical laboratory indicators, and the size of the pressure ulcers decreased to some extent. The patient was discharged after 1 month of hospitalization. This case highlights that accurate diagnosis is critical for administration of precise treatment to paraplegic patients with progressive rhabdomyolysis.

Car Seat Heater Burns: Awareness and Prevention

The demand for car seat heaters is on the rise due to the added comfort they offer passengers. However, such luxury is not without risk and prolonged exposure to high surface temperatures of the seat may result in severe burns. We present a unique case of an 18-year-old paraplegic patient who sustained severe full-thickness burns requiring operative intervention after prolonged exposure to a car seat heater. We then tested 10 car seat heaters manufactured after 2014 to establish maximum temperature settings and safety features. We also examine the importance of raising awareness to this issue and share the concerns of previous publications regarding the lack of manufacturer standards in car seat heaters.

Successful Management of Rhabdomyolysis with Acute Infection Resulting from Chronic Sacrococcygeal Pressure Ulcers in a Paraplegic Patient: A Case Report

Background: Rhabdomyolysis, a potentially life-threatening syndrome, is caused by the breakdown of skeletal muscle cells and leakage of intramyocellular contents into the bloodstream. The treatment of cases with rhabdomyolysis resulting from chronic sacrococcygeal pressure ulcers have been rarely reported.Case presentation: A 62-year-old man suffered from high fever and dark-colored urine. For the past 30 years, the patient has lived with paraplegia, which led to his immobility. According to his physical examination, the wound on his sacrococcygeal region was dehisced and exuded repeatedly with loss of skin sensation. Upon corroboration of a physical examination and laboratory tests, the patient was diagnosed with rhabdomyolysis with an acute infection resulting from sacrococcygeal pressure ulcers. We first debrided the necrotic tissue, and then the chronic ulcer was repaired. The wound dressing was changed frequently, and antimicrobial therapy and nutritional support were included in the treatment. The fever and dark-colored urine were gradually relieved post-operatively. Renal function was also improved according to the typical indicators in laboratory tests. Additionally, the size of the pressure ulcers was reduced, to some extent. The patient was discharged after one month of hospitalization.Conclusions: Accurate diagnosis is critical for clinicians to administer precise treatment to paraplegic patients with progressive rhabdomyolysis.

Robust T-S Fuzzy Control of Electrostimulation for Paraplegic Patients considering Norm-Bounded Uncertainties

This manuscript presents a Takagi–Sugeno fuzzy control for a mathematical model of the knee position of paraplegic patients using functional electrical stimulation (FES). Each local model of the fuzzy system is represented considering norm-bounded uncertainties. After obtaining the model of FES with norm-bounded uncertainties, the fuzzy control strategy is designed through the solution of linear matrix inequalities (LMIs) using the conditions available in the literature, which consider these norm-bounded uncertainties. The strategy considers decay rate and constraints on the input signal. The model is simulated in the Matlab environment using the numerical parameters measured by experimental tests from a paraplegic patient.
