1/163. Salvage of contaminated fractures of the distal humerus with thin wire external fixation.Fractures and osteotomies of the distal humerus that are contaminated or infected represent a difficult management problem. Stable anatomic fixation with plates and screws, the acknowledged key to a good result in the treatment of bicondylar fractures, may be unwise. A thin wire circular (Ilizarov) external fixator was used as salvage treatment in such complex situations in five patients. The fixator allowed functional mobilization of the elbow while allowing achievement of the primary goal of eradicating the infection or colonization. Two patients required a second operation for fixation of a fibrous union of the lateral condyle. One patient with a vascularized fibular graft later required triple plate fixation for malalignment at the distal host and graft junction. Four of five patients ultimately achieved complete union. The fracture remained ununited in one patient who has declined additional intervention. All five patients achieved at least 85 degrees ulnohumeral motion, two after a secondary elbow capsulectomy performed after healing was achieved. This experience suggested that the Ilizarov construct, although not a panacea, represents a reliable method of skeletal stabilization that allows functional mobilization while elimination of infection or colonization is ensured. If necessary, stiffness and incomplete healing can be addressed with an increased margin of safety at subsequent operations.- - - - - - - - - - ranking = 1keywords = capsule (Clic here for more details about this article) |
2/163. Systemic mycoses during prophylactical use of liposomal amphotericin b (Ambisome) after liver transplantation.We investigated the prophylactical administration of liposomal amphotericin b (Ambisome) in the early phase after liver transplantation (LTx). Fifty-eight patients received Ambisome prophylactically after LTx. Ambisome (1 mg kg-1 day-1) was given intravenously for 7 days after LTx. Immunosuppressive prophylaxis was cyclosporin A (CsA) based in 11 patients. Forty-seven patients had a tacrolimus-based immunosuppressive regimen. CsA and tacrolimus dosages were adjusted to trough levels of 150-250 ng ml-1 (EMIT) and 5-15 ng ml-1 (MEIA II) respectively. Three patients died from sepsis due to aspergillus fumigatus infection. Reasons for a fatal outcome were foudroyant Aspergillus pneumonia in a patient transplanted for fulminant hepatic failure on post-operative day (pod) 8; Aspergillus sepsis with severe endocardidtis in a patient with two retransplantations for graft non/dysfunction on pod 24; and disseminated aspergillosis due to aspergillus fumigatus in a patient retransplanted for primary non-function (pod 19). All three patients underwent haemofiltration for renal failure. One patient with candida albicans sepsis (pod 4) recovered under increased dosage of Ambisome (3 mg kg-1 per day). Ambisome (1 mg kg-1 per day) seems to be beneficial against systemic Candida infections. However, the onset of systemic Aspergillus infections could not be prevented. Obviously, higher Ambisome doses appear to be necessary against Aspergillus. We recommend the use of Ambisome (3 mg kg-1 per day) for patients with risk factors such as graft dys-/non-function, retransplantation, haemofiltration and complicated acute liver failure to prevent invasive aspergillosis.- - - - - - - - - - ranking = 14.647607170748keywords = pod (Clic here for more details about this article) |
3/163. Accumulation of milky fluid: a late complication of cataract surgery.We describe 3 patients who presented with an accumulation of homogeneous milky fluid in the capsular bag several years after continuous curvilinear capsulorhexis, phacoemulsification, and posterior chamber intraocular lens (IOL) implantation. In each case, the entire edge of the anterior capsule opening was tightly attached to the peripheral IOL optic. The milky fluid was present in the closed chamber between the IOL optic and the posterior capsule. The fluid was sampled in 2 patients, and its concentration of sodium hyaluronate was determined by high-performance liquid chromatography. The concentration of sodium hyaluronate resembled that in normal aqueous humor. In 1 case, the protein concentration was measured and found to be elevated. electrophoresis showed that human serum albumin was the main protein constituent. While the outcome was favorable in all 3 patients, this delayed complication of cataract surgery merits further study to clarify its etiology and pathogenesis.- - - - - - - - - - ranking = 2keywords = capsule (Clic here for more details about this article) |
4/163. Intraarticular methyl methacrylate: a complication of hip surgery.Methyl methacrylate, used as a grout during hip arthroplasty, can inadvertently become lodged between acetabular and femoral components during surgery. After resumption of ambulation, crescentic fragments may extrude into the pseudocapsule. If mobile methyl methacrylate fragments lodge within the joint, late surgical failure may result because of methyl methacrylate's abrasive character. Two cases of total hip replacement and one case of femoral arthroplasty are reported in which intraarticular methyl methacrylate was identified retrospectively; all three patients remain asymptomatic at the time of the report.- - - - - - - - - - ranking = 1keywords = capsule (Clic here for more details about this article) |
5/163. Non-traumatic liver rupture due to a perforated gastric ulcer.The case of a 57-year-old woman with a fatal liver rupture due to a necrotizing perihepatic abscess caused by a perforated gastric ulcer is presented. The ulcer had been treated successfully by surgical intervention 8 days before. The autopsy revealed a large perihepatic abscess and multiple ruptures of Glisson's capsule with a large subcapsular hematoma and underlying lacerations of the liver parenchyma. The patient had no history of previous abdominal trauma and the known etiological factors for spontaneous liver rupture were excluded by the autopsy findings or by clinical and laboratory data. No liver penetration by the gastric ulcer was found at autopsy and there were no clinical signs or symptoms for an infection or any degenerative or inflammatory diseases. Histologically abundant vegetable fibers, identified as stomach contents and a dense infiltrate of lymphocytes and granulocytes were found in the perihepatic abscess next to Glisson's capsule. Below Glisson's capsule there were hemorrhages, focal hepatocellular necrosis and a mixed cell inflammatory infiltration. In the present case, preceding perforation of the gastric ulcer with leaking of gastric acid into the peritoneal cavity resulted in peptic digestion of Glisson's capsule. Vascular lesions of the affected parts of Glisson's capsule and the liver parenchyma underneath resulted in intrahepatic hemorrhage and an increase in intrahepatic pressure with subsequent liver rupture. To the authors' knowledge no similar case of spontaneous liver rupture due to perforation of a gastric ulcer has been reported previously.- - - - - - - - - - ranking = 5keywords = capsule (Clic here for more details about this article) |
6/163. Cystic schwannomas of the jugular foramen: clinical and surgical remarks.OBJECTIVE: The goals of this report were to outline the clinical presentation, radiological characteristics, surgical techniques, postoperative morbidity, and long-term follow-up results for cystic jugular foramen (JF) schwannomas and to describe their differences, compared with solid schwannomas involving the JF. methods: A retrospective analysis of radiological studies and surgical records identified five primarily cystic tumors among 21 cases of JF schwannomas that had been surgically treated at our institution. RESULTS: Two types of cystic JF schwannomas were observed, i.e., Type 1 lesions, which are single large cysts with thin ring-like enhancement of the tumor wall, and Type 2 lesions, which are multiple cysts with very irregular, thick enhancement of the cyst wall. The most common symptoms were hearing loss, ataxia, and headaches. Total surgical removal could be performed in all cases. The immediate postoperative findings indicated hearing improvement in three cases. No deterioration of lower cranial nerve function was observed. All patients were independent in the immediate postoperative period and in the long-term follow-up period (Karnofsky Performance Scale score, 90). CONCLUSION: Surgical treatment of cystic JF schwannomas can be very demanding because of generally stronger adhesion of the tumor capsule to the surrounding structures, fragile tumor capsules, and difficulty in identification of the arachnoidal planes in some cases. Early identification of the arachnoidal planes without opening of the cyst and sharp dissection may be useful. Careful intradural opening of the JF should be performed to achieve total removal of the last tumor portion within the JF. A comparison of these lesions with solid schwannomas involving the JF indicated that cystic tumors affected a younger population, with less preoperative swallowing impairment (P < 0.05). The immediate postoperative course in both types of cystic JF schwannomas was usually better than for solid lesions, because of minor postoperative cranial nerve morbidity, especially involving lower cranial nerve function, in the latter cases. Long-term follow-up data failed to demonstrate any significant differences in final patient outcomes, however.- - - - - - - - - - ranking = 2keywords = capsule (Clic here for more details about this article) |
7/163. diagnosis and documentation of central nervous system dysfunctions with craniocorpography after surgical removal of acoustic neurinomas.Among other tests, craniocorpography (CCG) was performed in 21 patients after acoustic neurinoma surgery. After surgery, 17 patients (81%) had a developing vestibular compensation or an already normal CCG pattern; 3 patients (14%) had signs of persisting central nervous system dysfunction, either localized to the brain stem or in combination with a cerebellar dysfunction, and 1 patient showed a delayed but sufficient compensation after removal of a neurinoma that compressed central nervous system structures. brain stem and cerebellar dysfunctions caused by tumor compression demonstrated a better vestibular compensation than dysfunctions caused by surgical manipulation, despite no evidence of cerebellar alteration. As an adjunct to complete neuro-otologic and neurologic examinations CCG could become a useful tool in the topodiagnosis of central nervous system dysfunctions after acoustic neurinoma surgery and therefore in the documentation and follow-up process of these patients.- - - - - - - - - - ranking = 3.661901792687keywords = pod (Clic here for more details about this article) |
8/163. Two cases of late postoperative capsular block syndrome.Two cases of late postoperative capsular block syndrome that occurred 4 and 8.5 years, respectively, were encountered. One case underwent phacoemulsification after continuous curvilinear capsulorhexis in his left eye. The other case had a can opener type capsulorhexis and underwent extracapsular cataract extraction with trabeculectomy. One-piece posterior chamber lenses were implanted in both cases. Upon slit-lamp examination, the posterior capsules were found distorted posteriorly; the capsular openings were apparently sealed by the lens optic. A whitish material existed between the intraocular lens optic and posterior capsule, with thick aggregation in a lower fifth space in case 1. After Nd:YAG laser anterior capsulotomy in case 1, the thick aggregate spread diffusely on the posterior capsule which was sunken completely for 4 weeks. After Nd:YAG capsulotomy, the distorted posterior capsule disappeared and the best corrected visual acuity was restored to 20/20 in both cases.- - - - - - - - - - ranking = 4keywords = capsule (Clic here for more details about this article) |
9/163. alcaligenes xylosoxidans and propionibacterium acnes postoperative endophthalmitis in a pseudophakic eye.PURPOSE: To report a case of persistent polymicrobial postoperative endophthalmitis caused by alcaligenes xylosoxidans and propionibacterium acnes in a pseudophakic eye. A. xylosoxidans is a gram-negative bacteria resistant to most antibiotics. methods: Case report. RESULTS: A 72-year-old man presented with clinical signs of endophthalmitis on the first postoperative day after a phacoemulsification procedure with posterior chamber intraocular lens, left eye. Initial treatment included topical, subconjunctival, and oral antibiotics. After initial clearing, there was recrudescence of infection on postoperative day 37 that prompted referral of the patient to the Cullen eye Institute. Treatment at that time included anterior chamber and vitreous taps with intravitreal antibiotic injections. Complete pars plana vitrectomy and intraocular lens explantation were eventually required because of persistent infection with a resistant organism. Cultures from the first procedure grew A. xylosoxidans and P. acnes. Cultures from the vitrectomy grew only A. xylosoxidans. At the final follow-up visit 6 months after the initial procedure. The eye was without inflammation with best-corrected visual acuity of 20/40. CONCLUSION: Both A. xylosoxidans and P. acnes can cause chronic progressive endophthalmitis after cataract extraction often resistant to corrective antibiotic therapy. Successful intervention may require complete vitrectomy with intraocular lens and capsule removal.- - - - - - - - - - ranking = 1keywords = capsule (Clic here for more details about this article) |
10/163. Hepatic portal venous gas: report of a case.Hepatic portal venous gas is easily diagnosed radiographically by the appearance of tubular lucencies branching horizontally from the porta hepatis and extending to within 2cm of the liver capsule. Associated conditions vary from benign to potentially lethal diseases which require emergency operations. A case of hepatic portal venous gas secondary to small bowel obstruction is presented and a review of the literature is also provided.- - - - - - - - - - ranking = 1keywords = capsule (Clic here for more details about this article) |
