1/31. Glanzmann's thrombasthenia. Report of two oral surgical cases using a new microfibrillar collagen preparation and EACA for hemostasis.Glanzmann's thromboasthenia is a rare congenital platelet disorder characterized by a prolonged bleeding time, a qualitative platelet defect, and severe hemorrhagic episodes. patients with this disorder have been managed by administration of blood and blood components (most recently, platelet-rich plasma and platelet concentrates) to control hemorrhage resulting from trauma or surgical procedures. The two case reports presented here illustrate the use of a local hemostatic agent (microfibrillar bovine collagen, Avitene) and a systemic fibrinolytic inhibitor (epsilon aminocaproic acid, Amicar) to control postoperative hemorrhage secondary to elective extraction of teeth. The clinical results demonstrate excellent postoperative hemostasis and support recent in vitro observation of platelet adherence to the collagen preparation. This provides an alternate therapeutic modality in the management of patients with Glanzmann's disease and possibly other disorders of platelet function.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/31. Postoperative mycobacterium chelonae endophthalmitis after extracapsular cataract extraction and posterior chamber intraocular lens implantation.OBJECTIVE: To describe a case of postoperative endophthalmitis caused by mycobacterium chelonae after extracapsular cataract extraction with posterior chamber intraocular lens implantation. DESIGN: Interventional case report. methods: The history and clinical presentation of a 66-year-old female patient, in whom a low-grade delayed-onset endophthalmitis and keratitis developed after extracapsular cataract extraction with posterior chamber intraocular lens implantation, is described. Microbiologic investigations of the scrapings of corneal infiltrate at the cataract incision site, aqueous humor and eviscerated material, and histopathologic study of eviscerated material and an enlarged cervical lymph node were performed. MAIN OUTCOME MEASURES: The clinical, histopathologic, and microbiologic findings in a case of low-grade delayed-onset endophthalmitis. RESULTS: Analysis of the direct smear of both the corneal infiltrate as well as the eviscerated material revealed acid-fast bacilli. M. chelonae was isolated from these specimens. Direct smear and culture of the aqueous humor were negative for bacteria (including mycobacteria) and fungus. Histopathologic examination of the eviscerated material showed a dense infiltration of polymorphonuclear leukocytes in the uveal tissue, extensive necrosis and hemorrhage, and exudates with hemorrhage in the vitreous cavity. Histopathologic examination of the lymph node revealed granulomatous inflammation with caseation necrosis, but did not reveal acid-fast bacilli. CONCLUSIONS: M. chelonae, although infrequent, should be considered an etiologic agent of delayed-onset, postoperative endophthalmitis and early bacterial diagnosis should help in institution of appropriate therapy.- - - - - - - - - - ranking = 6keywords = extraction (Clic here for more details about this article) |
3/31. Rhinoorbitocerebral actinomycosis.PURPOSE: To report a case of actinomycotic orbital abscess with subdural empyema and pansinusitis, an unusual presentation of a rarely seen infection. methods: Case report. RESULTS: A 35-year-old man sought treatment for signs and symptoms of an orbital abscess 22 days after a dental extraction. Computed tomography demonstrated a left orbital abscess with left pansinusitis and a large subdural empyema. Surgical clearance of all purulent material was done followed by prolonged penicillin therapy. culture of pus from all sources yielded actinomycosis israelii. At the time of discharge and 1-month follow-up, the patient had 20/20 vision with no neurologic deficits. CONCLUSIONS: In orbital infections with atypical presentations, unusual pathogens should be considered as the causative agents.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
4/31. Pott's puffy tumor and epidural abscess arising from dental sepsis: a case report.OBJECTIVE: To present an unusual case of two uncommon cranial complications of frontal sinusitis: Pott's puffy tumor and epidural abscess arising from frontal sinusitis of dental origin, and also two systemic complications of sinusitis: septicemia and empyema, all occurring in an immunocompetent patient. STUDY DESIGN: A 21-year-old man presented with a scalp swelling and epidural abscess. magnetic resonance imaging and computed tomographic scans revealed unilateral opacification of the frontal sinus and an epidural abscess with a direct connection to the scalp abscess. Further history revealed that his symptoms occurred coincidentally with a tooth extraction 2 months before, and he was hospitalized soon after the tooth extraction for sepsis and a lung abscess. methods: A combined neurosurgical and otolaryngologic approach was required to treat the sinusitis and the associated epidural and scalp abscess. RESULTS: Cultures returned as streptococcus intermedius from all three sites. The patient was free of disease at the 3-month follow-up. CONCLUSIONS: Odontogenic maxillary sinusitis is well documented; however, there is little reported of frontal sinusitis arising from dental disease. The prevalence of sinusitis of dental origin will be reviewed, including the microbiology of this particularly virulent organism that persisted despite earlier treatment with ampicillin. Also, the current thoughts on management of these cases will be discussed with particular reference to local therapy for sinusitis in addition to systemic treatment with antibiotics.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
5/31. Potentially fatal oro-facial infections: five cautionary tales.Five cases of oro-facial infection leading to life-threatening complications are reported. Although all had been treated with antibiotics prior to maxillofacial referral, lack of surgical intervention had allowed progressive infection. The importance of resuscitation, supportive therapy, extraction of involved teeth to remove the source of infection and drainage of pus is emphasised- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
6/31. Coronary abscess: a complication of stenting.We report the case of a 72-year-old male who underwent primary angioplasty for an acute myocardial infarction and developed a coronary stent infection with staphylococcus aureus. The patient was treated with a prolonged course of IV antibiotics and underwent debridement and partial stent extraction successfully.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
7/31. Percutaneous removal of retained calculi from the abdomen.With rising pressure placed on health service resources minimally invasive techniques requiring only short hospital admissions are increasing in importance. We describe the techniques used to remove calculi from the peritoneal cavity which had been retained after surgery and continued to cause clinical problems. In both cases described the calculi lay within abscess cavities associated with fistulous tracks to the skin. The fistulae were dilated to allow passage of therapeutic radiologic and endoscopic equipment enabling manipulation and subsequent extraction of the stones. In both cases removal of the calculi allowed complete resolution of the fistulae and the patients made a full clinical recovery. Removal of gallstones which have escaped into the peritoneum at laparoscopic cholecystectomy leading to sepsis has been described; we describe the novel management of a patient in whom extraction had already been attempted, at another hospital, without success. Removal of an appendicolith, described here in another patient, does not appear to have been reported previously.- - - - - - - - - - ranking = 2keywords = extraction (Clic here for more details about this article) |
8/31. Infratemporal and submasseteric infection following extraction of a non-infected maxillary third molar.A case is described where an otherwise fit young female patient developed a large submasseteric abscess following the uneventful extraction of a non-infected maxillary third molar under local anaesthesia with intravenous sedation. This report highlights the difficulty of clinical diagnosis especially in the early stages of the infection. This case also demonstrates the imaging modalities used to confirm the diagnosis. It is likely that the infection in this case arose in an infratemporal fossa haematoma resulting from reactionary haemorrhage. Careful injection of local anaesthetic with aspiration may prevent this complication arising. This is the first reported case of a submasseteric abscess associated with the extraction of a clinically non-infected maxillary third molar.- - - - - - - - - - ranking = 6keywords = extraction (Clic here for more details about this article) |
9/31. actinomycosis abscess of the thyroid gland.OBJECTIVES: To present an unusual case of actinomycosis abscess of the thyroid gland as well as review the history, etiology, pathogenicity and treatment of actinomycosis infections of the head and neck. STUDY DESIGN: Case study. methods: A report of a 39 year-old female status post tooth extraction that developed an actinomycosis abscess of the thyroid. RESULTS: After a thyroid actinomycosis abscess was suggested by physical exam, ultrasound, CT scan and needle aspiration, an otolaryngology consult was obtained. The patient successfully was managed with thyroidectomy and intravenous ceftriaxone. CONCLUSIONS: Although actinomycosis soft tissue infections of the head and neck are relatively uncommon, the head and neck surgeon must include it in the differential diagnosis when clinical presentation raises suspicion. Early biopsy is necessary for appropriate identification of the organism with the appearance of sulfur granules lending a clue to the diagnosis. debridement and/or excision are often necessary for antibiotics to be used successfully. Antimicrobial therapy should be used for six to twelve months to completely eradicate the disease and prevent recurrence.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
10/31. Recurrent scleral abscess after uncomplicated cataract extraction.PURPOSE: To report the unusual occurrence of a recurrent scleral abscess after uncomplicated cataract extraction. methods: Case report of a 77-year-old healthy woman. RESULTS: Multiple cultures and antibiotic treatments failed to resolve presenting symptoms. Gram stain, Gomori methenamine silver (GMS) stain, and all cultures were negative. After drainage of the abscess, the patient's symptoms cleared briefly, then returned 6 months later showing a positive GMS stain consistent with candida. The patient was treated with amphotericin, natamycin, and fluconazole at this time, and a return in visual acuity occurred along with a resolution of symptoms. No re-occurrence has been noted with 2.5 years of follow-up. CONCLUSIONS: cataract extraction, although generally a safe procedure, can still result in unusual complications such as scleral abscesses. Excellent outcomes are possible once the infections are identified and treated.- - - - - - - - - - ranking = 6keywords = extraction (Clic here for more details about this article) |
