1/18. A case of an intraocular foreign body due to graphite pencil lead complicated by endophthalmitis.We report a case of an 8-year-old boy who presented with an intraocular foreign body composed of graphite pencil lead. The patient had been accidentally poked in the right eye with a graphite pencil. Primary care consisted of corneal suturing and lens extraction. Two pieces of the pencil lead remained in the vitreous cavity following surgery, and 2 days later the patient developed endophthalmitis. Pars plana vitrectomy was performed immediately and the intraocular foreign bodies were removed through the scleral wound. Cultures of the vitreous fluid revealed no bacterial organisms. X-ray fluoroscopic analysis of the vitreous detected 1 ppm of aluminum (a constituent of the pencil lead). Although the clinical presentation indicated probable bacterial endophthalmitis, the detection of elemental aluminum within the vitreous cavity also suggested the possibility of further retinal toxicity due to some dissolving of the pencil lead.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/18. Partial rupture of the tricuspid valve after extraction of permanent pacemaker leads: detection by transesophageal echocardiography.Traumatic lesions of the tricuspid valve complicating pacemaker lead extractions appear to be rare. We report two cases of partial rupture of the tricuspid valve, following apparently uneventful extraction of permanent ventricular leads, resulting in severe regurgitation and, in one case, chronic heart failure. TEE was useful to identify the traumatic mechanism of tricuspid regurgitation (TR) and the extent of valvular lesions in these patients. Such etiology should be suspected, and TEE performed, in patients developing TR or heart failure late after lead extraction.- - - - - - - - - - ranking = 7keywords = extraction (Clic here for more details about this article) |
3/18. eye injuries associated with paintball guns.AIMS: This study identifies the various types of ocular injuries sustained after blunt trauma with a paintball fired from a paintball gun. methods: We report two patients who sustained injury to an eye after being shot with a paintball and review similar cases presented in the world literature. The type of injury sustained and the final visual acuity obtained after a paintball hit to the eye are examined. RESULTS: The two boys presented were hit in the eye with a paintball resulting in lens subluxation, hyphema formation, and angle recession. cataract extraction was required in both cases. One boy also had an optic neuropathy and a choroidal rupture. A review of the literature reveals a variety of injuries occur after a paintball hit to the eye. In some of the cases, the damage to the eye has led to loss of vision and at times loss of the eye. CONCLUSIONS: Paintball guns can cause devastating ocular injuries. Wearing protective eye and face gear during this game is essential. We recommend that an anti-fog face mask with a one-piece polycarbonate eye shield be worn by those participating in paintball games.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/18. Is the loss of gallstones during laparoscopic cholecystectomy an underestimated complication?Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan.Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
5/18. Epilenticular intraocular lens implantation in traumatic cataract with a ruptured posterior capsule.PURPOSE: To present a case of rapidly progressing traumatic cataract caused by posterior capsule rupture after nonpenetrating ocular injury, as well as a surgical procedure to safely implant the intraocular lens in such a traumatized eye. methods: In a 23-year-old man with traumatic cataract and posterior lens capsule rupture, a one-piece polymethylmethacrylate IOL was implanted before cataract extraction into the ciliary sulcus in front of the cataractous lens. Subsequently, the cataract was removed by pars plana lensectomy. RESULTS: The surgery and postoperative course were uneventful. Postoperative visual acuity was 20/20. CONCLUSION: We present a method of intraocular lens implantation in cases of rapidly progressing traumatic cataract caused by posterior capsule rupture after a blunt ocular trauma.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/18. indocyanine green staining in traumatic cataract.We report the first case of indocyanine green (ICG) being used in an eye with an anterior capsule that was not completely intact. We found that ICG seems to have a selective affinity for the anterior capsule over cortical lens material. The patient had a corneal perforation with a wire and developed endophthalmitis requiring pars plana vitrectomy with intravitreal antibiotics. He subsequently developed a white traumatic cataract with an anterior capsule tear. Five months after the injury, he had cataract extraction. indocyanine green was used to better visualize the anterior capsule before capsulotomy. The anterior capsule stained green, but the cortical material exposed to ICG did not stain.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/18. An "exploding cataract" following Nd:YAG laser iridectomy.A case of an "exploding" cataract (an iatrogenic posterior capsular rupture) following Nd:YAG laser iridectomy is described. Rapid cataract development was observed in the right eye of a 76-year-old woman following an iridectomy. B-scan ultrasonography documented cortical debris in the vitreous cavity. The patient underwent an extracapsular cataract extraction and intraocular lens implantation. During the cataract extraction, a posterior capsular tear extending from the 10-o'clock to the 4-o'clock position was noted, through which fluffy cortical material was floating in the vitreous.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |

9/18. diagnosis and treatment of cauda equina entrapment in the vertical lamina fracture of lumbar burst fractures.Posterior dural lacerations associated with lumbar burst fractures are caused by impaction of the dural sac into the vertical lamina fracture. Neural elements may be extruded outside of the dura and become entrapped in the lamina fracture. This diagnosis must be made before surgery and is based on the patient's clinical presentation, the fracture pattern, and the radiographic findings. Entrapped neural elements can be successfully extracted from the lamina fracture by an opening laminoplasty of the posterior neural arch. patients with lumbar burst fractures and radiographic evidence of posterior displacement of the neural elements in the lamina fracture should undergo posterior exploration of the spinal canal, extraction of cauda equina neural elements, and repair of the dural laceration before any spinal reduction maneuver.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/18. Management of traumatic rupture of the globe in aphakic patients.We report the successful treatment of three cases of traumatic ruptures of the globe complicated by massive choroidal hemorrhage, uveal prolapse and retinal detachment. All three of the eyes were aphakic prior to injury and all patients were age 64 or older. The presenting visual acuity in all patients was light perception. The blunt injury in each case caused a wound dehiscence at the site of previous cataract extraction. All injuries were associated with uveal prolapse. Secondary surgical intervention was performed when the hemorrhagic choroidal detachments had decreased as demonstrated by echography in the suprachoroidal space, occurring at an average of 14 days after injury. The management consisted of surgical drainage of the choroidal hemorrhage combined with vitrectomy and silicone oil injection. Successful reattachment of the retina was achieved in all cases. Postoperative epiretinal membranes formed in two cases but all were anatomically successful at six months. Final visual acuities varied from 20/70 to 1/200, visual acuity being a function of secondary contusive damage to the retina and choroid. We believe that in eyes sustaining severe blunt injuries resulting in rupture of the globe complicated by massive choroidal hemorrhage and retinal detachment, properly timed external drainage of the choroidal hemorrhage combined with pars plana vitrectomy and silicone oil injection is a useful approach.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
