ABSTRACT

Introduction: Isocyanates are the raw materials that make up all polyurethane products. Isocyanate is a powerful irritant to the mucosal membrane of the respiratory tract, eyes and skin. Pulmonary symptoms, especially occupational asthma, are predominant manifestations of isocyanate toxicity. Case report: We report mental changes and compartment syndrome complicated with rhabdomyolysis as an extraordinary manifestation of acute isocyanate toxicity observed in a patient during the waterproofing of a water tank. A 58-year-old man recovered consciousness after six hours in the emergency department and complained of severe pain in the lower leg. The results of his laboratory test showed that his serum creatine kinase (15,250 IU/L) level had increased. The tissue pressure in both the lower legs had increased to 180 mmHg/170 mmHg (right/left). We performed fasciotomy on the second day of hospitalization. The patient was provided hyperbaric oxygen (HBO2) therapy of 2.0 ATA for 90 minutes twice a day for seven days. His condition gradually improved over five months, and he did not require amputation. He had a mild neurological disorder in his foot and was transferred to a rehabilitation center five months after hospitalization. Conclusion: It is important to note that when working with isocyanate, non-specific complications such as a change in consciousness as well as compartment syndrome with rhabdomyolysis can occur in a confined space or high-temperature environment. In addition, we found that compartment syndrome caused by isocyanate toxicity can be effectively treated with fasciotomy and HBO2 therapy.

ABSTRACT

We previously showed that transfer of adult myoblasts (MB) into cardiotoxin-damaged muscle improved the properties of reinnervated tibialis anterior muscle of rabbits. However, this cell therapy protocol cannot be applied to humans because of the hazardous effects of the myotoxin. To circumvent this approach, we used the recently developed high-density injection technique to autotransplant cultured cells 1 mm from each other into the tibialis anterior muscle without previous cardiotoxin-induced damage. Two months after transection and immediate suture of the common peroneal nerve, we transferred by this technique two types of precursor cells, MB or cells isolated from the adipose tissue stromal vascular fraction. In contrast to our previous results, muscles studied at 4 months showed no benefits in terms of function or morphology, whatever the transferred cells. These results, together with the results of earlier studies, emphasize the importance of delivery methods and the muscle environment in supporting cell integration into host tissues.

ABSTRACT

Acute compartmental syndrome (CS) is a surgical emergency. Different conditions in which high non-physiological pressure appears within a closed fascial space reduce the necessary blood perfusion. CS is caused by trauma, burns, bleeding in patients with coagulopathies arterial injuries, nephrotic syndrome or unusual physical exercise with secondary compartmental swelling. When decompression occurs too late, permanent loss of function and limb contracture may result. In the following paper we report on a case of four-compartmental syndrome in the lower legs of a patient with drug intoxication. After cannabis consumption, the patient fell asleep sitting cross-legged. During our first examination several hours later, the signs of compartmental syndrome with spontaneous pain, turgid swelling and paresis were present. Bilateral skin incision technique was used to gain entrance into the four compartments in both lower legs. Immediately after the operation, the patient showed crush syndrome with high serum creatine kinase activity 140.501 U/l and acute renal failure caused by rhabdomyolysis. Within 2 weeks of haemofiltration and dialysis, a full recovery to a normal serum creatinine level of 0.7 mg/dl was achieved. After emergency treatment and rehabilitation, the patient showed neither vascular nor neural defects.

ABSTRACT

An account is given of unusual course of a hyperthermic crisis in a 23-year-old male who underwent repeated anesthetics. As yet little has been reported about Isoflurane, which we presume to have been the triggering agent. In this case only the surgically untreated lower extremity developed rigor, with which malignant hyperthermia is associated, whereas the surgically treated extremity, where circulation had been stopped with a tourniquet, remained unaffected. Rigor and contracture of the affected extremity were so severe that they led to a compartment syndrome, necessitating fasciotomy. No observation of this kind has been published before. In addition to a discussion of this dissociated effect in malignant hyperthermia, a detailed account of the course of the crisis is given.

ABSTRACT

This is the first reported case of acute anterior tibial compartment syndrome following ergotamine tartrate overdosage. A 25-year-old man developed signs and symptoms of ergotism after ingestion of 72 mg of ergotamine tartrate over the 12 days prior to his hospital admission. On the fourth hospital day, the patient developed bilateral anterior tibial compartment syndrome. The development of this syndrome is postulated to have been due to the progressive edema and tissue pressure in the anterior tibial compartments, worsened by the gradual improvement of the peripheral circulation which followed the diminished vasopastic effect of the ergotamine.
