1/62. Sight-threatening acute orbital swelling from peribulbar local anesthesia.Severe allergic reactions to peribulbar local anesthesia are extremely rare. A 70-year-old woman presented with acute orbital swelling and optic nerve dysfunction after a peribulbar local anesthetic injection. The patient was treated with acute orbital decompression as well as intravenous antibiotics and methylprednisolone; she made a good recovery. An allergy, probably to lignocaine, was the most likely cause. Urgent recognition and treatment of this condition may prevent potentially serious visual consequences.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
2/62. Anticonvulsant hypersensitivity syndrome occurring as sepsis with multiorgan dysfunction.phenytoin is a highly effective and widely prescribed anticonvulsant agent. However, it is associated with both dose-related side effects and hypersensitivity reactions. life-threatening anticonvulsant hypersensitivity syndrome in one patient was characterized by a skin eruption and multisystem organ dysfunction.- - - - - - - - - - ranking = 47.3252030404keywords = organ (Clic here for more details about this article) |
3/62. Lamotrigine overdose presenting as anticonvulsant hypersensitivity syndrome.OBJECTIVE: To describe the laboratory and physical manifestations of lamotrigine toxicity presenting as anticonvulsant hypersensitivity syndrome. CASE SUMMARY: A 49-year-old white man presented to our institution with a two-day history of low-grade fever, erythema, and edema involving the periorbital area. Five days earlier, he had been placed on lamotrigine treatment for bipolar disorder. He inadvertently received four daily doses of lamotrigine 2700 mg each. physical examination was significant for periorbital edema and discrete and confluent blanching red macules and papules involving the face, trunk, and extremities. Laboratory tests revealed leukocytosis, hepatitis, and acute renal failure. With normalization of the laboratory results, the eruptions and edema gradually resolved. DISCUSSION: Lamotrigine toxicity can lead to periorbital edema, rash, and multiorgan system abnormalities. This presentation has clinical and laboratory similarities with anticonvulsant hypersensitivity syndrome, which suggests that at some threshold concentration the amount of lamotrigine may overwhelm the body's ability to metabolize the drug, leading to a similar hypersensitivity reaction. Lamotrigine is a relatively new agent, and this report may provide useful insights on evaluating the clinical toxicology of this agent. CONCLUSIONS: Healthcare providers should be aware that lamotrigine overdose may present with multiorgan involvement, similar to anticonvulsant hypersensitivity syndrome.- - - - - - - - - - ranking = 18.93008121616keywords = organ (Clic here for more details about this article) |
4/62. Treatment of bacterial endocarditis with vancomycin.Five patients with bacterial endocarditis who were allergic to penicillin were treated successfully with vancomycin. The causative microorganisms were streptococcus bovis, S faecalis, S agalactiae, S intermedius, and Staphylococcus aureus. Except for the strain of S faecalis, vancomycin was bactericidal against these organisms at easily achievable serum concentrations. To insure a bactericidal serum titer of 1:8 or greater, streptomycin was added in the therapy of the case caused by S faecalis. There was no toxicity from vancomycin therapy in our patients except for mild phlebitis at the infusion site. vancomycin appears to be an effective alternative to penicillin in individuals with endocarditis due to susceptible organisms. vancomycin in combination with an aminoglycoside may be appropriate therapy for enterococcal endocarditis.- - - - - - - - - - ranking = 28.39512182424keywords = organ (Clic here for more details about this article) |
5/62. Hypersensitivity syndrome due to 2 anticonvulsant drugs.Drug-induced hypersensitivity syndrome is a multiorgan-system reaction characterized by fever, pleomorphic eruption, lymphadenopathy, eosinophilia, lymphocytosis and hepatitis. We report a drug hypersensitivity syndrome in a 6-year-old Tunisian child treated for epileptic absences with sodium valproate and ethosuximide. Imputability of these 2 drugs is probable because of the chronological and clinical features. Positive rechallenge with ethosuximide confirmed the toxicity of this drug. sodium valproate was also responsible because patch testing was positive and followed by a generalized eruption. Human herpesvirus 6 (HHV6) antibody titers increased significantly within 15 days. There was a favourable outcome after discontinuation of the drugs and corticosteroid therapy. Our case is interesting because this drug hypersensitivity syndrome occurred with non-aromatic anticonvulsant drugs. It is the 1st case with ethosuximide and the 2nd with sodium valproate. We also observed a reactivation of HHV6 infection that may contribute to the development of this hypersensitivity syndrome.- - - - - - - - - - ranking = 9.46504060808keywords = organ (Clic here for more details about this article) |
6/62. Relapsing acute pancreatitis induced by re-exposure to the cholesterol lowering agent bezafibrate.We report a 75-yr-old patient, who presented three times with acute pancreatitis, accompanied by high temperature, shock, and multiorgan involvement and associated each time with exposure to the cholesterol lowering agent bezafibrate. Extensive workup excluded other possible causes for recurrent pancreatitis in this patient, further supporting bezafibrate as the cause of the patient's acute illness. Based on the short time elapsing between rechallenge and development of manifestations and the specific features of the attacks, we proposed hypersensitivity to bezafibrate as the underlying mechanism. The present report includes, for the first time, bezafibrate among definite causes of acute pancreatitis.- - - - - - - - - - ranking = 9.46504060808keywords = organ (Clic here for more details about this article) |
7/62. colitis may be part of the antiepileptic drug hypersensitivity syndrome.PURPOSE: To show that colitis may be part of the antiepileptic hypersensitivity syndrome. methods: Description of two case histories. RESULTS: The first patient was a 47-year-old man who developed fever, lymphadenopathy, influenza-like symptoms, facial edema, skin rash and diarrhea after 3 weeks of carbamazepine (CBZ) treatment. laparotomy because of severe abdominal pain 2 weeks later showed severe colitis with perforations. The second patient was a 41-year-old woman who developed fever, diarrhea, and skin rash 4 weeks after start of CBZ treatment. A colon biopsy confirmed colitis. Stool examinations did not show pathogenic microorganisms, and there was no evidence of Crohn's disease or ulcerative colitis. Both patients had elevated liver enzymes, peripheral eosinophilia, and eosinophils in the infiltrate of the colon. CONCLUSIONS: In view of the close temporal relation between start of CBZ intake and development of colitis, the presence of fever, lymphadenopathy, and rash, and improvement after discontinuation of CBZ, we conclude that the two patients developed an AED hypersensitivity syndrome. Our case histories demonstrate that severe colitis may be part of this syndrome.- - - - - - - - - - ranking = 9.46504060808keywords = organ (Clic here for more details about this article) |
8/62. Anticonvulsant hypersensitivity syndrome.BACKGROUND: Anticonvulsant hypersensitivity syndrome (AHS) is a serious but poorly understood and little known disease. It has been variously described in the literature since 1934. Fatalities are rare but have been reported. methods: A medline search was undertaken from 1991 to present, using the keywords "anticonvulsant," "phenytoin," and "hypersensitivity." English language articles and their endnotes were reviewed, and neurologists, dermatologists, and specialists in hematology-oncology were consulted. RESULTS: A case of AHS is described. Investigators have reported epidemiologic data and described the pathophysiology, diagnostic criteria, and management options. CONCLUSIONS: family physicians should be aware of the AHS because of the high likelihood that patients with this syndrome will come first to their primary care physicians for care. Certain anticonvulsant medications have a high degree of cross-reactivity, the incidence of AHS is higher among first-degree relatives, and the disorder mimics systemic infection. If AHS is suspected, the antiepileptic drug should be discontinued. Supportive care should be directed to the appropriate organ systems, with particular attention to skin, eyes, and liver. Corticosteroid treatment might be effective in reversing the drug reactions, but it is not recommended in cases of suspected or actual infection because of the increased risk of immunocompromise, sepsis, and associated mortality.- - - - - - - - - - ranking = 9.46504060808keywords = organ (Clic here for more details about this article) |
9/62. A case report of olanzapine-induced hypersensitivity syndrome.Hypersensitivity syndrome is defined as a drug-induced complex of symptoms consisting of fever, rash, and internal organ involvement. The hypersensitivity syndrome is well recognized as being caused by anticonvulsants. Olanzapine is an atypical antipsychotic agent whose side effects include sedation, weight gain, and increased creatinine kinase and transaminase levels. To date, there have been no reports of hypersensitivity syndrome related to this drug. A 34-year-old man developed a severe generalized pruritic skin eruption, fever, eosinophilia, and toxic hepatitis 60 days after ingestion of olanzapine. After termination of olanzapine treatment, the fever resolved, the skin rash was reduced, eosinophil count was reduced to normal, and the transaminase levels were markedly reduced. Clinical features and the results of skin and liver biopsies indicated that the patient developed hypersensitivity syndrome caused by olanzapine.- - - - - - - - - - ranking = 9.46504060808keywords = organ (Clic here for more details about this article) |
10/62. vancomycin anaphylaxis in a patient with vancomycin-induced red man syndrome.vancomycin is a powerful glycopeptide antibiotic that is increasingly being used owing to the emergence of highly resistant organisms such as methicillin-resistant staphylococcus aureus. Although a generally safe medication, administration of vancomycin is not benign, and there have been a number of adverse reactions reported. We present the case of a patient with vancomycin-induced red man syndrome who developed vancomycin anaphylaxis. Our case illustrates that red man syndrome may be a marker for true vancomycin allergy, although it was generally not thought of as so in the past.- - - - - - - - - - ranking = 9.46504060808keywords = organ (Clic here for more details about this article) |
