1/101. 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) |
2/101. Successful use of alternate waste nitrogen agents and hemodialysis in a patient with hyperammonemic coma after heart-lung transplantation.BACKGROUND: Lethal hyperammonemic coma has been reported in 2 adults after lung transplantation. It was associated with a massive elevation of brain glutamine levels, while plasma glutamine levels were normal or only slightly elevated. In liver tissue, glutamine synthetase activity was markedly reduced, and the histologic findings resembled those of reye syndrome. The adequacy of therapy commonly used for inherited disorders of the urea cycle has not been adequately evaluated in patients with this form of secondary hyperammonemia. OBJECTIVE: To determine whether hemodialysis, in conjunction with intravenous sodium phenylacetate, sodium benzoate, and arginine hydrochloride therapy, would be efficacious in a patient with hyperammonemic coma after solid-organ transplantation. DESIGN: Case report. SETTING: A children's hospital. PATIENT: A 41-year-old woman with congenital heart disease developed a hyperammonemic coma with brain edema 19 days after undergoing a combined heart and lung transplantation. methods: Ammonium was measured in plasma. amino acids were quantitated in plasma and cerebrospinal fluid by column chromatography. The effectiveness of therapy was assessed by measuring plasma ammonium levels and intracranial pressure and performing sequential neurological examinations. RESULTS: The patient had the anomalous combination of increased cerebrospinal fluid and decreased plasma glutamine levels. To our knowledge, she is the first patient with this complication after solid-organ transplantation to survive after combined therapy with sodium phenylacetate, sodium benzoate, arginine hydrochloride, and hemodialysis. Complications of the acute coma included focal motor seizures, which were controlled with carbamazepine, and difficulty with short-term memory. CONCLUSIONS: The aggressive use of hemodialysis in conjunction with intravenous sodium phenylacetate, sodium benzoate, and arginine hydrochloride therapy may allow survival in patients after solid-organ transplantation. An acute acquired derangement in extra-central nervous system glutamine metabolism may play a role in the production of hyperammonemia in this illness that resembles reye syndrome, and, as in other hyperammonemic disorders, the duration and degree of elevation of brain glutamine levels may be the important determining factors in responsiveness to therapy.- - - - - - - - - - ranking = 0.70016260272162keywords = organ (Clic here for more details about this article) |
3/101. Diffuse acute cellulitis with severe neurological sequelae. A clinical case.The incidence of head and neck odontogenic infections considerably diminished in the last decades due to appropriate antibiotic therapy. Herein we describe a case of acute diffuse facial cellulitis following tooth extraction in a patient with no apparent risk factor. During the acute process, injury was caused to the hypoglossal, vagal, glossopharyngeal and recurrent nerves of both sides. For this reason the patient currently has a nasogastric line for enteral feedings and a tracheotomy tube, which significantly affects his quality of life.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
4/101. Ultrasonographically guided injection of corticosteroids for the treatment of retroseptal capillary hemangiomas in infants.PURPOSE: Injection of corticosteroids is a well-documented and successful mode of treatment for periorbital capillary hemangiomas. Because of the greater potential risk involved with retrobulbar injections, no prior study has described this treatment for tumors located behind the orbital septum. Although retroseptal intraorbital capillary hemangiomas comprise only 7% of all adnexal capillary hemangiomas, complications such as optic nerve compression or astigmatism may necessitate treatment. methods: Three patients with deep orbital hemangiomas that caused vision-threatening complications were treated with intralesional injections of triamcinolone and betamethasone. Orbital injection was performed with use of real-time ultrasonographic guidance of the needle. This technique was valuable in providing continuous, accurate, and safe advancement of the needletip in the orbit to avoid the globe and orbital walls. ultrasonography also permitted precise placement of the needle tip within the tumor and visualization of the injected material. RESULTS: Significant improvement was demonstrated in all cases on the basis of both ultrasonographic measurements and regression of clinical manifestations such as astigmatism, chemosis, proptosis, and optic nerve pallor. No complications were noted. CONCLUSION: Intralesional injection of corticosteroids to treat retroseptal and retrobulbar capillary hemangiomas was found to be a safe and effective treatment modality in our patients. Positioning of the injecting needle was guided by ultrasonography.- - - - - - - - - - ranking = 2keywords = nerve (Clic here for more details about this article) |
5/101. Acute renal failure after a sea anemone sting.A 27-year-old man suffering from severe swelling and pain in his right arm was referred to our hospital. He showed signs of acute renal failure (ARF) with severe dermatitis of his right arm. Three days before being admitted, he accidentally touched some kind of marine organism with his right hand while snorkeling in the Sulu Sea around Cebu Island. Within a few minutes, he was experiencing severe pain in his right hand. Then his right hand gradually became swollen. The marine creature responsible for this injury was thought to have been a sea anemone, which is a type of coelenterate. Histologic findings of a renal biopsy indicated that acute tubular necrosis (ATN) had caused ARF in this patient's case. Supportive therapies improved renal function of this patient, and steroid pulse therapy attenuated the severe skin discoloration. The ATN was thought to have been caused by the poison from a sea anemone because there were no other conceivable reasons for the patient's condition. This is the first time that a marine envenomation case has been reported in which the sting of a sea anemone has caused ATN without the failure of any other organs.- - - - - - - - - - ranking = 0.46677506848108keywords = organ (Clic here for more details about this article) |

8/101. clostridium sordelli infection.A case of human clostridium sordelli soft tissue infection is presented. Analysis of this patient's course led to the use of a mouse experimental model for examination of this organism's potential for toxin production. Data thus obtained correlated with that seen in this instance of human infection, indicates that the lethal effects of this organism may be related to the ability to clostridium sordelli to produce a widespread "toxin-mediated" edema with subsequent marked "third-space" sequestration of fluid.- - - - - - - - - - ranking = 0.46677506848108keywords = organ (Clic here for more details about this article) |

Neuropathological examination of the brain showed intra- and extracellular white matter edema while spinal cord, peripheral nerves and muscles were normal. Hygroma colli as the first echographic sign of subsequent severe fetal akinesia sequence without muscular dystrophy as seen in the Lethal Multiple pterygium syndrome has not been previously reported.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
10/101. Remitting seronegative symmetrical synovitis with pitting oedema in a patient with myelodysplastic syndrome and relapsing polychondritis.Remitting seronegative symmetrical synovitis with pitting oedema (RS3PE) may be the inaugural manifestation of different rheumatic diseases of the elderly, malignancies and myelodysplastic syndromes (MDS). Relapsing polychondritis (RP) is a rare systemic disorder characterised by an inflammatory process involving predominantly cartilaginous structures, the cardiovascular system and organs of special sense. We report on a 72-year-old man with RS3PE and MDS, refractory anaemia subtype, diagnosed at the same time as RS3PE. Several months later the patient presented a clinical and pathological picture compatible with RP. Although the association between RP and MDS is well known, no previous cases of RS3PE preceding RP have been reported. This case confirms that RS3PE may herald many diseases, among others autoimmune disorders such as RP.- - - - - - - - - - ranking = 0.23338753424054keywords = organ (Clic here for more details about this article) |
