131/1101. Nosocomial submandibular infections with dipterous fly larvae.

    In September 1998, a case of nosocomial cutaneous myiasis caused by Lucilia sericata (Meigen, 1826) in a 77-year-old male was found. The patient had been receiving partial maxillectomy due to the presence of malignant tumor on premaxilla. This is the first verified case involving Lucilia sericata in Taegu, korea. In the present paper, the salient morphological features of the third instar larvae involved have been studied. ( info)

132/1101. Management of radiated reoperative wounds of the cervicothoracic spine: the role of the trapezius turnover flap.

    reoperation for malignant disease of the cervicothoracic spine can lead to compromised wound healing secondary to poor tissue quality from previous operations, heavily irradiated beds, and concomitant steroid therapy. Other complicating factors include exposed dura and spinal implants. Introducing well-vascularized soft tissue to obliterate dead space is critical to reliable wound healing. The purpose of this study was to determine the efficacy of the trapezius turnover flap in the management of these complex wounds. This study is a retrospective review of all patients undergoing trapezius muscle turnover flaps for closure of complex cervicothoracic wounds after spinal operations for metastatic or primary tumors. Six patients (3 male/3 female) were operated over an 18-month period (mean patient age, 43 years). Primary pathologies included radiation-induced peripheral nerve sheath tumor (N = 2), chondrosarcoma (N = 1), nonsmall-cell lung cancer (N = 1), paraganglioma (N = 1), and spindle cell sarcoma (N = 1). Trapezius muscle turnover flaps were unilateral and based on the transverse cervical artery in every patient. Indication for flap closure included inability to perform primary layered closure (N = 3), open wound with infection (N = 2), and exposed hardware (N = 1). All patients had previous operations of the cervicothoracic spine (mean, 5.8 months; range 2-9 months) for malignant disease and prior radiation therapy. Exposed dura was present in all patients, and 2 patients had dural repairs with bovine pericardial patches. Spinal stabilization hardware was present in 4 patients. All patients underwent perioperative treatment with systemic corticosteroids. All flaps survived, and primary wound healing was achieved in each patient. The only wound complication was a malignant pleural effusion communicating with the back wound, which was controlled with a closed suction drain. All wounds remained healed during the follow-up period. Four patients died from progression of disease within 10 months of surgery. The trapezius turnover flap has been used successfully when local tissue conditions prevent primary closure, or in the setting of open, infected wounds with exposed dura and hardware. The ease of flap elevation and minimal donor site morbidity make it a useful, single-stage reconstructive option in these difficult wounds. ( info)

133/1101. Infection is an unusual but serious complication of a femoral artery catheterization site closure device.

    Percutaneous devices have been developed to close the femoral artery puncture site after catheterization. Because direct compression is not needed, the devices save time for the treating health-care provider, reduce patient discomfort, and obviate the need for post-catheterization bed rest. Reported complications with use of these devices are similar in nature and frequency to those accompanying direct compression. Complications of infection requiring surgical treatment are exceedingly rare with use of these devices. We describe a series of five catheterization site infections occurring among 1807 patients (0.3%) whose femoral artery puncture was closed with a percutaneous suture closure device. All patients required operative intervention and there was one late death. physicians should be aware of this uncommon but serious complication to expedite evaluation and treatment of patients with suspected infections from these devices.

134/1101. Purulent and constrictive pericarditis arising from a staphylococcal lumbar infection.

    A 78-year-old man was admitted to the hospital for evaluation and treatment of anasarca secondary to staphylococcal purulent pericarditis. One month earlier he had undergone a lumbar laminectomy that was complicated postoperatively by a lumbar abscess that was not clinically apparent. The infection subsequently spread to the pericardium. Despite aggressive therapy that included therapeutic pericardiocentesis, drainage of pericardial fluid, and prolonged intravenous antibiotic therapy, the patient returned 2 weeks after discharge from the hospital with complicating constrictive pericarditis. pericardiectomy was performed, resulting in complete relief of the patient's symptoms.

135/1101. Severe hemorrhagic complication due to acquired factor v inhibitor after single exposure to bovine thrombin product.

    Hemorrhagic complications have been reported after repeated exposures to bovine thrombin products due to development of factor v inhibitors. Our patient underwent emergency repair of acute aortic dissection and coronary artery bypass grafting. The patient developed leg wound infection at the saphenous vein harvest site, which was debrided and left open. Attempt to reclose the leg wound 1 month later was complicated by a life-threatening hemorrhage with markedly elevated activated partial thromboplastin time. There was no evidence of infection or disseminated intravascular coagulation, and further study identified low factor v level with positive factor v inhibitor. Treatment with plasmapheresis and steroid successfully reversed the coagulopathy. Detailed case review failed to reveal exposure to any thrombin products other than the one used for the aortic dissection repair. This case was unusual because only a single exposure to this product resulted in severe hemorrhagic complication 1 month after surgery. ( info)

136/1101. Ultrasound features of osteosarcoma of the mandible--a first report.

    Ultrasound imaging is becoming widely used in the head and neck region as a first-line investigation to assess soft tissue swellings. Clinicians should be aware of the potential of diagnostic ultrasound to identify important signs of malignant disease involving bone.Involvement of the mandible by osteosarcoma is uncommon. A young adult patient presented with facial swelling and an apparently infected lower third molar extraction socket. Subtle signs were missed on dental radiographs. Diagnostic ultrasound investigation was pivotal in identifying sinister signs: namely, soft tissue mass associated with bone thinning, erosion, expansion, and the "sunray" appearance of the buccal cortex, which were suggestive of osteosarcoma. These findings enabled priority to be given to subsequent investigations using other modalities. We present a first report of the ultrasound features of osteosarcoma of the mandible and consider this to be a useful modality in an initial investigation. ( info)

137/1101. Toxic shock syndrome associated with the use of the vacuum-assisted closure device.

    The vacuum-assisted wound closure technique and device (the V.A.C.) has become a widely accepted technique in the management of chronic and difficult wounds. The authors present the first reported case of toxic shock syndrome associated with its use. This article does not question the efficacy of the V.A.C. technique in the treatment of difficult wounds, but focuses on raising the index of suspicion of toxic shock syndrome in patients with wounds managed with the V.A.C. who develop early signs or symptoms that may be consistent with the diagnosis.

138/1101. femoral artery infections associated with percutaneous arterial closure devices.

    hemostasis obtained by manual compression after femoral artery catheterization results in consistently low rates of major complications. A rare complication of femoral artery catheterization is arterial infection. Its occurrence after diagnostic angiography using manual compression has not been reported. We report two cases of femoral arterial infection after uneventful diagnostic catheterization in nonimmunocompromised patients using the Perclose percutaneous arterial closure device. Our cases are representative of Perclose associated infections, with delayed presentation of a staphylococcal arterial infection requiring arterial debridement and reconstruction. This article indicates that Perclose use carries a risk of severe arterial infection. Surgeons should be aware of the potential infectious complications associated with Perclose use and the need for aggressive treatment. ( info)

139/1101. aspergillus niger infection of exenterated orbit.

    PURPOSE: To present two immunocompetent patients with aspergillus niger infection of the exenterated orbit. methods: case reports. RESULTS: The patients were treated with oral itraconazole and socket irrigation with amphotericin b. The sockets cleared completely; no growth was observed on reculturing. CONCLUSIONS: A niger infection of an exenterated socket can be effectively treated with oral itraconazole and topical amphotericin b in immunocompetent patients. ( info)

140/1101. Retroperitoneal gas gangrene complicating elective inguinal hernia repair.
