1/197. prognosis of acute poststreptococcal glomerulonephritis in childhood: prospective study and review of the literature.Serial, clinical, clinicopathologic and histologic studies performed simultaneously following onset of PS-AGN in children for a period of up to 144 months revealed no evidence of progression to chronic glomerulonephritis. Although acute morphologic changes were more severe in renal tissue obtained from patients with AGN following streptococcal upper respiratory infection than following pyoderma, the acute manifestations in both groups subsided 6 to 12 weeks after onset. Cumulative morphologic healing occurred in 20% of patients at 24 months, in 43% at 48 months after onset of PS-AGN; 1 patient who was unhealed at 49 months was lost to follow-up. In 2 patients (6%), acute histologic exacerbations without clinical signs occurred within 24 months after onset. Subsequent healing was documented histologically. Addis counts remained abnormal in a high percentage of patients throughout the 12 years of observation and did not correlate with the histologic findings of renal biopsy tissue. The occasional demonstration of renal vascular disease and/or hypertension may merely reflect the early development of spontaneous essential hypertension although the possibility of a relationship to the previous attack of PS-AGN is intriguing. This question cannot be answered at this time. Renal biopsy studies are more dependable than Addis counts in assessing the course of PS-AGN. The significance of persistence of immunofluorescent and/or electron microscopic changes (subepithelial dense deposits) many years after onset in 58% of 12 patients studied, at a time when a majority of patients (84%) revealed healing by light microscopy, remains to be assessed.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
2/197. Removal of infected pacemaker leads with deep hypothermic circulatory arrest and open surgical exploration of the superior vena cava and innominate veins.Despite the use of transvenous methods for extraction of infected leads, failed attempts may result in retained lead fragments. Retained lead fragments may be a focus of continued infection leading to sepsis. We present two patients in which conversion from cardiopulmonary bypass to hypothermic circulatory arrest allowed direct visualization, using venotomies in the superior vena cava and innominate vein to achieve complete removal of retained pacemaker lead fragments. Use of venotomies in the extracardiac venous system is a technical addition to prior descriptions of lead extraction using deep hypothermia and circulatory arrest.- - - - - - - - - - ranking = 13.343062589299keywords = tract (Clic here for more details about this article) |
3/197. Group A streptococcus causing PID from an initial pharyngeal infection. A case report.BACKGROUND: pelvic inflammatory disease (PID) is a difficult diagnosis. Five billion dollars is spent on over 1 million women diagnosed each year. Atypical organisms and prior history of tubal ligation may complicate the diagnosis. CASE: A woman who had undergone tubal ligation and abstained from intercourse for over two years developed group A streptococcal salpingitis. It occurred following an upper respiratory infection with the same organism. CONCLUSION: PID is rare in a woman with prior tubal ligation who is not engaging in intercourse. In this case it followed an upper respiratory infection with group A streptococcus. Low diagnostic suspicion must be maintained for uncommon pathogens in PID in women with prior tubal ligation who are not engaging in intercourse.- - - - - - - - - - ranking = 2keywords = upper (Clic here for more details about this article) |
4/197. Severe pulmonary hemorrhage in patients with serious group A streptococcal infections: report of two cases.Severe pulmonary hemorrhage was observed in two patients who died of serious group A streptococcal infections. These two patients initially presented with fever and sore throat. This was followed by sudden onset of septicemia caused by the bacteria and by the subsequent development of severe pulmonary hemorrhage. hemoptysis, cyanosis, and dyspnea were observed prior to death in both cases. This pulmonary lesion resulted in asphyxia and sudden death in one patient. Pathological examinations of the lung revealed severe intraalveolar hemorrhage, with no evidence of inflammation or necrosis of the pulmonary tissue. There was no evidence of aspiration of blood due to hemorrhage in the upper respiratory or alimentary tract. This visceral lesion appears to be an hitherto undescribed, novel clinicopathologic feature of patients with serious group A streptococcal infections.- - - - - - - - - - ranking = 7.6715312946497keywords = tract, upper (Clic here for more details about this article) |
5/197. osteomyelitis, lateral sinus thrombosis, and temporal lobe infarction caused by infection of a percutaneous cochlear implant.OBJECTIVE: cochlear implantation has become a routine operation in the last 10 years. The most common soft tissue complications with transcutaneous cochlear implants include infection or necrosis of the flap and extrusion of the implant and device failure. The most common complication reported with percutaneous devices include minor skin irritations at the pedestal site, retraction of skin from the pedestal site, and loosening of screws that retain the pedestal. We describe one case of lateral sinus thrombosis and secondary temporal lobe infarction caused by infection of a screw anchoring the percutaneous pedestal of an Ineraid implant. STUDY DESIGN: Case report. SETTING: Tertiary referral center. CONCLUSIONS: Intracranial complications of a percutaneous bone-anchored pedestal may occur with little prodrome. Computed tomography (CT) scan of the pedestal and bone anchoring screws may be indicated if local evidence of infection persists.- - - - - - - - - - ranking = 6.6715312946497keywords = tract (Clic here for more details about this article) |
6/197. Brain abscesses from neglected open head injuries: experience with 17 cases over 20 years.We are reviewing our experience with 17 civilian cases with post-traumatic brain abscesses treated in the era of CT scanning over a period of 20 years. The principal cause for this intracranial complication was the neglected compound depressed fracture. One was a newborn infant with left parietal abscess caused by a vacuum extraction. We have used the following methods of treating the abscesses: single burr hole aspiration in the newborn with an excellent result; repeated aspiration, with debridement of the depressed fracture, in 5 cases (1 death); aspiration with early subsequent excision, via craniotomy, in 7 cases (no death), and primary excision, via craniotomy, in 4 cases (1 death). The early subsequent excision of the abscess, 2 or 3 days after the initial aspiration, has proved in our experience very satisfactory. In cases with bone fragment into the abscess cavity the excision of the abscess is indicated. The cultured pus from the abscess cavity showed mixed flora (streptococci and staphylococci) in 7 cases; staphylococcus aureus in 4; staphylococcus epidermidis in 2, and no growth in 4 cases. Antibiotics play an important role in the treatment of post-traumatic brain abscesses.- - - - - - - - - - ranking = 6.6715312946497keywords = tract (Clic here for more details about this article) |
7/197. Primary peritonitis due to group A streptococcus.Primary peritonitis is a rare condition occurring, by definition, in patients without underlying causes, such as perforated viscus, pre-existing ascites, or nephrosis. We report a case of primary peritonitis and shock due to group A beta-hemolytic streptococcus, a rare etiology. A review of the world's literature shows a predilection for women to have this condition. The entry site is obscure in most cases. Asymptomatic genital tract colonization may be a portal of entry in some women. shock or toxic shock syndrome often accompany the abdominal findings. laparotomy to exclude a perforated viscus may be unavoidable. Despite the significant morbidity, expeditious and appropriate antibiotic therapy is curative.- - - - - - - - - - ranking = 6.6715312946497keywords = tract (Clic here for more details about this article) |
8/197. brain abscess following delayed endoscopic removal of an initially asymptomatic esophageal coin.Brain abscesses are rare occurrences in pediatric patients, and making their diagnosis can be difficult. The two most commonly cited risk factors are otorhinologic infections and cyanotic congenital heart disease (CCHD). We present a 13-month-old child with a brain abscess who, 2 weeks prior, underwent rigid endoscopy for the extraction of a coin from the esophagus. We believe this to be the first such report of a brain abscess after rigid endoscopy for removal of an esophageal foreign body. In this case the esophageal coin was initially asymptomatic and had been present for weeks prior to removal. The potential association between delayed coin extraction and development of an intracranial infection, suggested by this report, may warrant investigation.- - - - - - - - - - ranking = 13.343062589299keywords = tract (Clic here for more details about this article) |
9/197. A devastating ocular pathogen: beta-streptococcus Group G.PURPOSE: To report the clinical findings, treatment, and outcomes of four cases of beta-streptococcus Group G (BHS-G) ocular infection. methods: The medical and microbiologic records of four cases of BHS-G ocular infection were retrospectively reviewed. RESULTS: Two cases of BHS-G endophthalmitis and two cases of BHS-G keratitis were recorded. Three patients developed fulminant infection within 12 hours of the onset of symptoms. One patient's history was incomplete. One patient developed endophthalmitis from a contaminated donor button; another following cataract surgery. One developed keratitis in a keratoplasty suture tract; and another patient developed a corneal abscess after being struck with a tree branch. The patient with the contaminated donor button developed overwhelming endophthalmitis resulting in no light perception vision, severe pain, and evisceration. The postoperative cataract patient developed a purulent endophthalmitis and is still hypotonus with light perception vision. The second keratitis patient developed a significant suture abscess with marked stromal loss but eventually healed. The traumatic keratitis patient developed a large ulcer with hypopyon and descemetocele but was lost to follow-up. CONCLUSIONS: This is the first report of a series of BHS-G ocular infections. The ocular infections were characterized by rapid onset, extreme inflammation, and--despite in vitro antibiotic sensitivity--a poor or sluggish response to antibiotic therapy.- - - - - - - - - - ranking = 6.6715312946497keywords = tract (Clic here for more details about this article) |
10/197. Reiter's syndrome caused by streptococcus viridans in a patient with hla-b27 antigen.A 26-year-old male patient with mitral valve prolapse and hla-b27 antigen received endodontic treatment for dental caries. Two weeks later fever, dysuria, diarrhea, sterile inflammatory arthritis of lower limbs, enthesitis, dactylitis, conjunctivitis, and uveitis consecutively developed. blood culture performed at the time of active arthritis yielded streptococcus viridans. He did not have any history of psoriasis, acute infectious diarrhea, chronic inflammatory bowel diseases, or sexually transmitted diseases. Laboratory studies also excluded the possibility of infections by human immunodeficiency virus, hepatitis b or C virus, chlamydia, and streptococci from the upper airway. This report indicates that streptococcus viridans can be the triggering microorganisms of Reiter's syndrome in some circumstances.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
