1/24. case reports offer a challenge to treatment strategies for immediate implants.The placement of osseointegrated implants in extraction sockets is a commonly used and reliable procedure. Many operative protocols have been suggested for use with both submerged and nonsubmerged implants, and some prerequisites have been defined for their successful placement. Dealing exclusively with implants placed in intact extraction sockets, this paper reviews these commonly suggested prerequisites, discusses their clinical relevance, and presents case reports in which clinical success was obtained despite the violation of more than 1 of these factors. Techniques to obtain primary implant stability, procedures to regenerate residual bone defects, the need to submerge implants in the healing phase, and treatment strategy in infected sites are reviewed. Because the simultaneous violation of some prerequisite factors allows postextractive implants to be performed with a single surgical approach, a new classification is proposed based on the number of surgical stages required to replace a failing tooth with an implant-supported restoration.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/24. Early acute aseptic iritis after cataract extraction.Severe iritis which occurs within the first five days after cataract extraction may be categorized as (1) bacterial endophthalmitis, (2) toxic iritis, or (3) aseptic iritis. These entities can sometimes be distinguished because of their clinical features. If bacterial endophthalmitis is suspected, anterior chamber paracentesis should be considered and appropriate antibiotic treatment should be initiated. Acute iritis may result from the introduction of toxic agents into the eye, and may follow the use of products sterilized with ethylene oxide. Early acute aseptic iritis probably occurs more often than has previously been recognized. Response to intensive anti-inflammatory treatment is usually prompt and dramatic. The judicious use of cryoextraction and the careful manipulation of intraocular tissues may minimize the incidence and the severity of postoperative inflammation.- - - - - - - - - - ranking = 3keywords = extraction (Clic here for more details about this article) |
3/24. Superficial temporal artery dilatation in a patient with infectious temporal headache clinically mimicking temporal arteritis.A 57-year-old woman noticed a pulsatile shooting headache in her right temporal region 3 days after extraction of a tooth from the right mandible. The following day, a localized headache over the right superficial temporal artery (STA), low grade fever, and jaw claudication appeared and progressed subacutely. Seven days after the onset, magnetic resonance imaging and angiography (MRI/MRA) disclosed inflammatory swelling of the right temporal muscle and dilatation of the right STA. All the symptoms disappeared following antibiotic treatment, and neuroimaging findings were improved. In conclusion, MRA is thought to be useful to non-invasively identify reversible inflammatory dilatation of extracranial vessels.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
4/24. Infected neonatal cephalohematomas caused by anaerobic bacteria.OBJECTIVE: To present the microbiological and clinical features of six children with infected cephalohematomas (IC) caused by anaerobic bacteria. DESIGN: Presentation of a case series. RESULTS: Polymicrobial infection was present in all instances, where the number of isolates varied from two to four. Two patients had anaerobes only and the other four had mixed flora of strict anaerobes and facultatives. There were 16 bacterial isolates (12 anaerobic, 4 aerobic). The anaerobic isolates were peptostreptococcus spp. (5 isolates), prevotella spp. (4), bacteroides fragilis group (2), and propionibacterium acnes (1). The aerobic isolates were E. coli (2), staphylococcus aureus (1) and group B streptococci (1). blood cultures were positive for three patients. The most common predisposing conditions were vacuum extraction and amnionitis (4 instances of each), instrumental delivery (3), electronic fetal monitoring (2), prolonged delivery (1), and premature rupture of membranes (1). All patients underwent drainage, and four also had surgical incision and drainage of the IC. osteomyelitis developed in one instance and scalp abscess developed in two patients, both of whom had electronic fetal monitoring. All patients eventually recovered from infection after receiving parenteral and subsequent oral antibiotic therapy for a total of 14-38 days. CONCLUSION: This study highlights the polymicrobial nature and potential importance of anaerobic bacteria in IC in newborns.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
5/24. diagnosis and treatment of chronic postoperative bacterial endophthalmitis.Bacterial endophthalmitis has been recognized as a significant cause of chronic, delayed-onset inflammation following extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens implantation. The diagnosis of chronic postoperative bacterial endophthalmitis should be suspected in any case of chronic, refractory inflammation following ECCE. Although successful treatment may require surgical intervention in some cases, others may respond to antibiotic therapy alone.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
6/24. endocarditis due to strain of cardiobacterium hominis resistant to erythromycin and vancomycin.endocarditis caused by cardiobacterium hominis was observed in a penicillin-allergic patient with a prosthetic cardiac valve who had received prophylactic therapy with erythromycin for dental extractions. The organism was resistant to erythromycin and vancomycin, with minimal inhibitory concentrations of 12.5 microgram/ml and 25 microgram/ml, respectively, but was sensitive to penicillin g, tetracycline, cephalexin, and cefaclor. This case suggests that currently recommended antibiotic prophylactic therapy for endocarditis, especially in penicillin-allergic patients, may be inadequate for unusual pathogens such as C hominis.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
7/24. endophthalmitis due to propionibacterium acnes sequestered between IOL optic and posterior capsule.A 68-year-old woman had delayed onset, persistent uveitis following routine extracapsular cataract extraction with posterior chamber intraocular lens implantation. The patient initially responded to topical steroids, but developed a whitish capsular plaque through to represent possible propionibacterium acnes endophthalmitis. A vitrectomy and capsular biopsy yielded cultures positive for P. acnes only after nine days. The intraocular lens was left in place. light and electron microscopy revealed bacteria sequestered within the capsular bag.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
8/24. diagnosis and treatment of chronic postoperative bacterial endophthalmitis.Chronic postoperative bacterial endophthalmitis has recently assumed a prominent role in differential diagnosis of inflammation following extracapsular cataract extraction with posterior chamber intraocular lens implantation. The optimal diagnostic and therapeutic approach to this entity has not yet been clearly defined. We present a case of chronic postoperative propionibacterium acnes endophthalmitis in which the diagnosis was made by anterior chamber paracentesis, and topical, periocular, and systemic antibiotic therapy resolved the inflammation. anterior chamber paracentesis for aerobic and anaerobic cultures may be an appropriate initial diagnostic step in suspected cases. While successful treatment may require surgical intervention in some cases, others may respond to antibiotic therapy alone.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
9/24. Chronic bacterial endophthalmitis.We studied a specific syndrome of uveitis secondary to intraocular bacterial pathogens of low virulence after extracapsular cataract extraction and intraocular lens implantation in three eyes. The onset of photophobia, visual impairment, conjunctival redness, and uveitis was delayed for four days to 12 weeks after surgery. Chronic inflammation persisted for five weeks to 16 months before a definitive diagnosis was made. signs and symptoms were suppressed by administration of topical and systemic corticosteroids. Intraocular biopsy and antibiotic injection both established the cause as bacterial endophthalmitis and resulted in resolution of signs and symptoms. staphylococcus epidermidis was cultured in two eyes and achromobacter was cultured in one.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
10/24. endophthalmitis following Nd:YAG laser posterior capsulotomy.We report the development of propionibacterium acnes endophthalmitis following Nd:YAG laser posterior capsulotomy. The patient previously underwent uncomplicated extracapsular cataract extraction with intraocular lens insertion and was free of inflammation prior to laser capsulotomy. Diagnostic vitrectomy and aqueous tap were performed, and P. acnes was isolated from the aqueous in thiol broth media after nine days of incubation under anaerobic conditions. The patient was managed with topical and systemic antibiotics and steroids. Complete resolution of inflammation with return of vision to 20/25 was achieved without removal of the intraocular lens or lenticular remnants.- - - - - - - - - - ranking = 0.5keywords = extraction (Clic here for more details about this article) |
