Intra-lesional IL-2 safely and effectively provides locoregional control of in-transit melanoma.
Background: Reverse end-to-side anterior interosseous nerve transfer has been reported to enhance treatment of severe, proximal ulnar neuropathy. The authors report on patients with severe neuropathy treated with ulnar nerve transposition and distal reverse end-to-side anterior interosseous nerve transfer. Methods: Thirty patients with severe ulnar neuropathy at the elbow were reviewed. Clinical parameters included preoperative and postoperative Medical Research Council muscle strength, clawing, and degree of wasting. Electrodiagnostic data included compound motor action potential and sensory nerve action potential amplitudes. Summary statistics were used for demographic and clinical data. The t test and Wilcoxon signed rank test were used where appropriate. Results: Average follow-up was 18.6 months. Preoperatively, 20 patients had Medical Research Council less than or equal to grade 1 in hand intrinsics, small finger sensory nerve action potentials were absent in all patients except for three, and average compound motor action potentials were severely reduced (absent in nearly 40 percent) confirming severity. All groups had a statistically significant increase in strength. More than three-quarters of patients noted partial or complete resolution of clawing and intrinsic muscle wasting. Seventy-three percent of patients regained Medical Research Council greater than or equal to grade 3 and 47 percent achieved Medical Research Council greater than or equal to grade 4. Mean time to observation of nascent units was 8.5 months, and 77 percent of patients demonstrated an augmentation of motor unit numbers with forearm pronation on needle electromyography Conclusion: Proximal subcutaneous ulnar nerve transposition when combined with reverse end-to-side anterior interosseous nerve–to–ulnar nerve transfer demonstrates significant clinical and electrodiagnostic improvement of intrinsic muscle function. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
Intra-lesional interleukin-2 (IL-2) is effective in treating in transit melanoma metastases. Results from multiple studies were examined to evaluate the efficacy of IL-2 for in transit disease. In the published literature, complete response ranged from 0% to 69% per patient, and 41% to 96% per lesion, with excellent tolerability. Combining the results of six studies show complete response in 50% of patients and 78% of lesions. Intra-lesional IL-2 should be considered early in the course of treatment for in transit disease, ahead of other, more toxic therapies.
Summary A 19-year-old woman with asphyxiation complicated by cardiac arrest, following an unsuccessful suicide attempt by hanging, developed an uncommon complication of trauma-induced thyroid storm. She was initially admitted to the intensive care unit intubated and mechanically ventilated for postcardiac arrest management. Investigation of thyroid storm was pursued after the patient was noted to be persistently hypertensive, tachycardic and agitated despite high levels of sedation. Thyroid function tests confirmed the clinical suspicion of progressive thyrotoxicosis, with associated imaging consistent with thyroid inflammation secondary to band-like traumatic pressure to the lower half of the thyroid gland. Treatment with β-blockers and a thionamide resulted in the eventual resolution of her thyroid storm state and normalisation of her thyroid function. We conclude that traumatically induced thyroid storm should be considered in all hypermetabolic patients following blunt neck injuries including hanging, and that traditional treatment of hyperthyroidism can be successfully applied.
Case: We present the unique case of deltoid and hand compartment syndrome in a young man after prolonged syncope because of polysubstance use. The patient was subsequently treated with urgent deltoid and hand compartment fasciotomies which resulted in full recovery of his shoulder function. Conclusions: Patients suspected of deltoid compartment syndrome should have a thorough physical examination, followed by repeat examinations. Invasive compartment monitoring should be used in equivocal cases, in patients with decreased level of consciousness, and in patients with distracting injury. Once diagnosed, deltoid compartment syndrome (± other compartments) should be taken for emergent fasciotomy, ensuring adequate decompression of all 3 deltoid compartments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
