1/1614. Group G streptococcal endocarditis.

    The group G streptococcus may be a more common human pathogen than previously recognized. A case of group G streptococcal endocarditis is reported and the 11 cases reported previously are reviewed. Group G endocarditis may have significant clinical and prognostic differences from endocarditis caused by the more commonly identified viridans or group D streptococci. Routine serologic grouping of beta-hemolytic streptococcal isolates from serious infections is warranted.

2/1614. Bacterial endocarditis in a patient with Marfan's syndrome.

    A patient with Marfan's syndrome and subacute bacterial endocarditis is presented. Echocardiographic studies demonstrated dilatation of the aortic root, prolapse of the posterior leaflet of the mitral valve, and the appearance of shaggy echoes on the anterior miltral leaflet, of the kind previously described as representing bacterial vegetations.

3/1614. Nonclostridial gas gangrene due to streptococcus anginosus in a diabetic patient.

    streptococcus anginosus was recently identified as a distinct species from the other members of streptococcus milleri group (streptococcus constellatus, streptococcus intermedius). We report a rare case of nonclostridial gas gangrene caused by S. anginosus. A 62-year-old diabetic woman was admitted with gas gangrene of the perineal area. She had been taking her oral hypoglycemia medication regularly for 10 years, but the diabetes was inadequately controlled. She was treated with surgical debridement of the necrotic tissue, insulin injection, and antibiotic therapy, and had a satisfactory clinical course.

4/1614. A case of Austrian's syndrome with ocular involvement.

    A man with a history of alcohol abuse was admitted to hospital with pneumonia and meningitis due to streptococcus pneumoniae. Because of the worsening of respiratory function and the persistence of fever, an echocardiographic examination was made, which showed endocarditis with destruction of the aortic valve. The patient underwent surgical valve replacement. In addition, he showed a choroiditis in the left eye which improved after antibiotic therapy. The interest of this case lies in the rarity of the triad described as Austrian's syndrome and in the coexistent fourth septic localization, namely in the left eye.

5/1614. Febrile perianal streptococcal dermatitis.

    We describe a child with an unusual presentation of perianal streptococcal dermatitis which included fever, acral scarletiniform desquamation, and extension of erythema to involve the genitalia and proximal thighs, as well as the commonly seen well-defined erythema of the perianal area. We suggest that isolated group A beta-hemolytic streptococci (GAS) in our patient produced a pyrogenic exotoxin similar to that which appears in scarlet fever.

6/1614. brain abscess caused by streptococcus intermedius: two case reports.

    BACKGROUND: Although streptococcus intermedius has been recognized as an important pathogen for abscess formation outside the central nervous system, the streptococcus milleri group, of which it is a member, has not been recognized as a specific pathogen for brain abscess, often thought to be caused by Streptococcus viridans, which includes other streptococcal species. CASE DESCRIPTION: Two cases of brain abscess in the left frontal lobe caused by S. intermedius, which responded well to antimicrobial treatment combined with needle aspiration, are presented. In the first patient, the predisposing disease was paranasal sinusitis of the frontal and ethmoid sinuses. In the second patient, the source of the pathogen was not detected despite extensive examination. The patients underwent aspiration of pus under ultrasound guidance in the first patient, and via a computed tomography-guided stereotactic procedure in the second patient. They subsequently received appropriate antimicrobial therapy against S. intermedius isolated from the pus culture. Both patients were discharged without any neurological deficits. CONCLUSION: It is important to recognize S. intermedius as a pathogen of brain abscess, and to be aware of its predisposing factors, i.e., mucosal disturbance and liver abscess.

7/1614. Late bleb-related endophthalmitis after trabeculectomy with mitomycin C.

    To present two cases of delayed-onset postoperative endophthalmitis following trabeculectomy combined with mitomycin C for secondary glaucoma after penetrating keratoplasty. We retrospectively evaluated two patients with late endophthalmitis after trabeculectomy combined with intraoperative mitomycin C application. Both patients underwent trabeculectomy for uncontrolled glaucoma following penetrating keratoplasty and they developed thin-walled cystic blebs. intraocular pressure was normal, and grafts remained clear postoperatively. Severe endophthalmitis with hypopyon developed at 3 and 7 months postoperatively. Both patients had concomitant bleb infection. They underwent vitreous sampling and intravitreal injection of vancomycin and amikacin and were given topical fortified and systemic antibiotic therapy. Intravitreal injection was repeated once in both patients. Cultures grew Streptococcus pneumonias in one and staphylococcus aureus in the other. Although the treatment of endophthalmitis was successful in both patients, only one of them achieved useful vision (20/40). For the other patient who had been infected with S. pneumoniae, vision was light perception. Delayed-onset endophthalmitis following trabeculectomy with mitomycin C application is a severe and vision threatening complication. It seems that the development of thin cystic filtering blebs secondary to intraoperative mitomycin C application may be a predisposing factor for bleb-related late endophthalmitis.

8/1614. Unusual evidence of myocardial involvement during a hypersensitivity reaction to oral penicillin.

    A hypersensitivity reaction to orally administered phenoxymethyl penicillin is reported. The manifestations of the reaction included fever, arthralgia, urticaria and an irregular pulse. Serial ECG showed second-degree atrioventricular block with junctional escape beats, an atypical Wenckebach pattern and, finally, first-degree atrioventricular block with gradually decreasing PR intervals. A normal tracing was recorded on the sixth day despite the persistence of the rash and joint pains.

9/1614. Fatal maternal beta-hemolytic group B streptococcal meningitis: a case report.

    meningitis secondary to beta-hemolytic group B streptococcus is rare and represents less than 1% of cases of adult meningitis. We report the first known case of maternal mortality attributed to beta-hemolytic group B streptococcal meningitis. A 23-year-old African-American woman with a benign prenatal course delivered a viable male infant at term. Labor was complicated by thick meconium for which a saline amnioinfusion was utilized. On postpartum Day 1, the patient complained of right hip pain and a headache. Within 12 hr the patient was comatose with fixed and dilated pupils. life support measures were discontinued secondary to absence of electrocortical activity. Postmortem examination revealed endomyometritis and fulminant meningitis with gram-positive cocci. Placental histologic sections demonstrated acute chorioamnionitis and bateriological cultures noted beta-hemolytic group B streptococcus. The virulence of beta-hemolytic group B streptococcus in the neonate is well recognized. This case demonstrates that beta-hemolytic group B streptococcus is also a potentially fatal maternal pathogen.

    A patient with basilar artery rupture caused by a septic embolus originating from a mitral valve vegetation is reported. The pathogenesis, investigation and management of infected cerebral aneurysms are reviewed.
