1/47. Bacterial complications of strongyloidiasis: streptococcus bovis meningitis.We report the case of a 64-year-old veteran who had streptococcus bovis meningitis as a result of a long latent strongyloides infection that became acute when he was treated with prednisone. We reviewed 38 reported cases of serious bacterial infections associated with strongyloidiasis. patients most frequently had nonspecific gastrointestinal symptoms. Of these 38 patients, 21 (55%) had meningitis, and 28 (73%) had bacteremia that was polymicrobial in 3 cases (8%). Other sites of infection included lung, bone marrow, ascites, mitral valve, and lymph node. Most infections were due to enteric gram-negative bacteria. There is one previously reported case of S bovis meningitis. Thirty-four of the patients (89%) were immunosuppressed; 21 of these (55%) were taking pharmacologic doses of adrenal corticosteroids. Thirty-three of the 38 (87%) patients died. patients with enteric bacterial infection without an obvious cause should be tested for the presence of strongyloidiasis.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
2/47. Neutrophil antigen 5b is carried by a protein, migrating from 70 to 95 kDa, and may be involved in neonatal alloimmune neutropenia.BACKGROUND: Neutrophil antigen 5b has been described as involved in transfusion reactions and not in neonatal alloimmune neutropenia. CASE REPORT: Anti-5b was found in the serum of a mother of a persistently neutropenic newborn, who had several bacterial infections. The neutropenia responded to treatment with recombinant human granulocyte-colony-stimulating factor. immunoprecipitation experiments performed with this and three other 5b antisera identified a protein, migrating from 70 to 95 kDa, as carrier of 5b. The observed pattern of migration may point to heavy glycosylation of this protein. RESULTS: Six 5b-negative donors were identified among 54 screened white donors, for a 5b gene frequency of 0.66. CONCLUSION: Alloimmunization to 5b in pregnancy is rare. In the patients with neonatal neutropenia analyzed in the last decade, this was the first case discovered.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
3/47. Necrotizing fasciitis after peritonsillar abscess in an immunocompetent patient.Cervical necrotizing fasciitis (CNF) is a rapidly progressive, severe bacterial infection of the fascial planes of the head and neck. Group A beta haemolytic Streptococcus spp. (GABHS), staphylococcus spp., or obligatory anaerobic bacteria are the most common causative pathogens. The disease usually results from a dental source or facial trauma. Extensive fascial necrosis and severe systemic toxicity are common manifestations of CNF. review of the literature reveals only seven such cases, with four successful outcomes. The authors present the case of a 50-year-old immunocompetent female with CNF arising from a peritonsillar abscess. Intravenous immunoglobulins in conjunction with surgery and antibiotics were used successfully. The authors also suggest the importance of the early diagnosis, aggressive surgical debridement, broad-spectrum antibiotics, and possible usefulness of the intravenous immunoglobulins in the treatment of CNF, especially when the disease is associated with toxic shock syndrome.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
4/47. Guttate psoriasis triggered by perianal streptococcal dermatitis in a four-year-old boy.Perianal streptococcal dermatitis (PSD) is a superficial bacterial infection usually with group A beta-hemolytic streptococci. PSD is often misdiagnosed for long periods and patients are subjected to treatments for a variety of differential diagnoses without success. We report a 4-year-old boy with PSD who presented to our clinic with guttate psoriasis for 2 reasons: first, to make dermatologists aware of PSD and second, to emphasize the necessity to examine patients, particularly pediatric patients, with guttate psoriasis very thoroughly and swab both the pharynx and perianal and/or perigenital areas even when they are, or seem to be, asymptomatic for bacterial infections. Once PSD has been diagnosed, systemic antibiotic therapy with penicillin, erythromycin, roxithromycin, or azithromycin (probably augmented by topical mupirocin ointment) should be the treatment of choice. Therapy should be monitored by posttreatment perianal and throat swabs as well as a urine analysis to monitor for poststreptococcal glomerulonephritis.- - - - - - - - - - ranking = 1keywords = bacterial infection (Clic here for more details about this article) |
5/47. Acute metastatic infection of a revision total hip arthroplasty with oral bacteria after noninvasive dental treatment.The risk of hematogenous bacterial infection of a total joint prosthesis is currently considered to be greatest in the 2 years after arthroplasty or when the patient is chronically ill or immunocompromised, for dental treatments that are considered invasive, with a higher incidence of bacteremia. We report the case of a healthy man who had undergone revision hip arthroplasty 11 months previously and who developed acute signs of infection of the hip prosthesis with an oral organism 30 hours after supragingival dental cleaning, performed with the specific intention to be noninvasive, without antibiotic prophylaxis.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
6/47. Congenital penoscrotal lymphedema complicated by sepsis associated with a streptococcal infection.Congenital lymphedema is a relatively rare disease caused by congenital abnormality of the lymphatic system. Although bacterial infection frequently causes complications with lymphedema, severe sepsis in congenital lymphedema of the genitalia has not yet been reported. We describe a patient with congenital penoscrotal lymphedema complicated by cellulitis, lymphangitis, and severe sepsis associated with a streptococcal infection. This case represents the importance of obtaining a detailed clinical history and physical findings.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
7/47. Group C streptococcal meningitis: case report and review of the literature.Group C streptococci are a common cause of epidemic bacterial infection in animals. These organisms are a rare but frequently fatal cause of meningitis in humans. We report the case of a 13-year-old girl with meningitis caused by a group C Streptococcus (Streptococcus zooepidemicus) successfully treated with vancomycin and third generation cephalosporins. We also review cases of group C streptococcal meningitis reported previously.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
8/47. discitis associated with pregnancy and spinal anesthesia.discitis (inflammation of the intervertebral disk) most commonly develops as a rare complication of bacterial infection or chemical or mechanical irritation during spine surgery (1) with a postoperative incidence of 1%-2.8% (2). It is also a complication of discography-the intradiscal injection of saline or contrast material (3). The incidence of postdiscography discitis is 1%-4% (3); no cases have been reported when prophylactic antibiotics have been used, supporting the theory of bacterial contamination (3). Although it is controversial whether discitis can be caused by an aseptic or infectious process, recent data suggest that persistent discitis is almost always bacterial (4). Honan et al. (5) reported 16 cases of spontaneous discitis and reviewed another 52 patients from the literature. In their series, patients tended to have one or more comorbid conditions, such as diabetes, vertebral fracture, or a preexisting spine injury. Spontaneous discitis has also been associated with advanced age, IV drug abuse, IV access contamination, urinary tract infection, and immunocompromised states (5,6). No cases of infectious discitis associated with pregnancy and spinal anesthesia have been reported in the English literature. discitis presents as spasmodic pain in the back that may be referred to the hips or groin (7). The pain may radiate to the lower extremities. The erythrocyte sedimentation rate is usually increased. Radiological changes in discitis include narrowing of the intervertebral disk space, vertebral sclerosis, and erosion of the end plates. The best diagnostic measure may be magnetic resonance imaging (MRI) or a combination of bone and gallium scanning (2). The mainstay for discitis treatment is pain control and antibiotics; surgical intervention is usually not required. Complications of discitis include intervertebral fusion, epidural abscess, and paralysis. IMPLICATIONS: This is a case report of a disk infection (discitis) caused by the bacteria, streptococcus bovis after spinal anesthesia for cesarean delivery. S. bovis rarely causes discitis, and spinal anesthesia for labor and delivery has not been reported as a cause of discitis.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
9/47. Acute generalized Hailey-Hailey disease.A patient with extensive histologically proven Hailey-Hailey disease is described whose initial clinical presentation was suggestive of erythema multiforme or toxic epidermal necrolysis. This potentially misleading morphology of acute proven Hailey-Hailey disease has not been described previously and may be a consequence of bacterial infection exacerbating acantholysis.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
10/47. Primary bacterial pericarditis.Purulent pericarditis is rarely the primary site of bacterial infection. It is usually a complication of an infection originating elsewhere in the body, arising by contiguous spread or haematogenous dissemination.This paper, however, describes a previously healthy young man, who developed a purulent streptococcal pericarditis with no localizable primary focus. Although many possibilities were investigated, the entry site of the pericarditis remains unknown.The incidence of purulent pericarditis has decreased considerably since the antibiotic era. It is typically an acute and potentially lethal disease, necessitating rapid diagnosis and adequate therapy to improve prognosis. Standard treatment combines appropriate antibiotic therapy with surgical drainage. However, the exact timing and type of surgery is still under discussion. Our patient was treated with antibiotics, subxiphoidal tube drainage of the pericardial fluid and intrapericardial thrombolysis. After three weeks, he developed tamponade, requiring partial pericardiectomy. He recovered completely and resumed his normal activities after a two-month hospitalisation.- - - - - - - - - - ranking = 0.5keywords = bacterial infection (Clic here for more details about this article) |
