In order to stress the need for continued vigilance in maintaining the highest standards of quality control for corneal tissue used for transplantation, we are presenting 2 cases of pneumococcal endophthalmitis which occurred in tissue transplanted from a young donor who died following acute trauma. The patient had been on cardiovascular support for over 26 hours and had suffered from a febrile illness which on autopsy revealed bronchial pneumonia. Both kidney recipients from the same donor died of myocardial infarctions on the same day in separate cities, 2 days after kidney transplantation surgery. Several recommendations are made which should assist all eye banks in providing the highest quality tissue and in preventing the occurrence of infection transmitted donor tissue.

The most frequently seen type of infectious ophthalmia neonatorum, inclusion conjunctivitis, is caused by the organism Chlamydia trachomatis. This agent is known to be transmitted sexually. Until recently, the infections produced by C trachomatis were though to be relatively benign. Recent evidence, however, suggests that the organism may produce urethritis and epididymitis in the male; cervicitis, cervical erosions, salpingitis, and puerperal infections in the female; and prematurity and pneumonitis in the infant. An infant who develops ophthalmia neonatorum should be thoroughly evaluated for the presence of a chlamydial infection. In many instances the first evidence of chlamydial infection within the parents will be the development of inclusion conjunctivitis in their newborn infant. Family members of infants with inclusion conjunctivitis who manifest any evidence of clinical disease should be evaluated and treated with appropriate antibiotics.

Two months after renal transplantation, a 26-year-old man developed pneumonia that was recalcitrant to antibiotic therapy and proved by biopsy to be due to cytomegalovirus and Aspergillus fumigatus. Ten days later while on amphotericin B therapy, he developed an endophthalmitis proved by smear and culture of a vitreous aspiration to be caused by A. fumigatus. Despite intravitreous and systemic amphotericin B the vision deteriorated and the eye was enucleated. Microscopic examination disclosed an intense endophthalmitis with vitreous and retinal abscesses. The second patient was a 29-year-old woman who developed severe hypertension and graft rejection one month after renal transplant, despite massive immunosuppressive therapy with prednisone, azathioprine, and cobalt 60 irradiation. She developed pneumonia, meningitis, and died. A postmortem examination revealed disseminated aspergillosis. A single choroidal abscess due to Aspergillus with an associated retinal hemorrhage was observed in the left eye.

Current methods used for the laboratory diagnosis of a Chlamydia trachomatis disease control program for a developing country are reviewed to guide clinical microbiology laboratories to develop criteria for testing. Human chlamydia infections are a major public health problem in both developed and developing countries. Worldwide an estimated 360 million persons are infected by the ocular serovars of Chlamydia trachomatis and 6.4 million are blind from the scarring, sequelae. The genital strains of Chlamydia trachomatis cause cervical, endometrial or tubal infections in women, resulting in pelvic inflammatory disease (PID) or ectopic pregnancy, and infertility. Over 50% of chlamydia infections in women are asymptomatic and progress to silent PID and infertility. In industrialized countries chlamydia infections are the major cause of sexually transmitted disease-related infertility. Infants born to infected mothers are at risk for chlamydia pneumonia and ophthalmia neonatorum. More tentative associations of chlamydia infections exist with Reiter's Syndrome. Early diagnosis of chlamydia infections is the most cost effective means of preventing the longterm sequelae of trachoma, pelvic inflammatory disease, ectopic pregnancy and infertility, which are a major public health liability in developing countries. In many developed and developing countries, public health decision maker are not aware of the extent of chlamydia infections in the community. One of the priorities of the disease control program is to provide accurate epidemiologic data through seroprevalence studies. This includes estimates of persons infected, the severity of complications and sequelae. Public health strategies are required to establish laboratory services and to diagnose and treat the disease. The diagnostic methods for C. trachomatis include specimen collection, cytologic methods, serologic methods, cell culture method, antigen detection methods, and nucleic acid hybridization tests that should be available at the national reference laboratory.

Chlamydia trachomatis is currently the most common sexually transmitted disease in the United States. The prevalence in pregnant women ranges between 2% and 47%. It is well known that C trachomatis can be transmitted from the genital tract of an infected mother to her newborn infant, causing conjunctivitis or pneumonia or both, along with their longstanding complications. A review of the literature failed to show, however, conclusive evidence of transmission of infection to the newborn infant when the infant was born by cesarean section with intact amniotic membranes. We present a case of a young black woman with a history of chlamydia cervicitis during pregnancy whose infant was delivered by cesarean section because of failure to progress. She gave birth to a healthy term infant who developed ophthalmia neonatorum on the 3rd day of life. Examinations of conjunctival scrapings with direct fluorescent staining (chlamydia MicroTrak) performed on the 1st and 3rd day of life were positive. The initial test was performed because of the maternal history. The infant was mildly symptomatic at the time the study was repeated for confirmation. Our findings strongly suggest the possibility of either transmembrane or transplacental route of infection in the pathogenesis of neonatal chlamydia infection. Further study is needed to confirm this possibility.

We made an investigation on central venous catheter related sepsis (CRS) in recent 5 years (1987-1991). The incidence of CRS was high; 16.0% (125 out of 782 cases) or 13.1% (135 out of 1029 catheters). CRS occurred frequently during 2-3 weeks after catheter insertion. The incidence of CRS was not affected by the kind of disease (malignant or benign), complication (diabetes, liver cirrhosis, collagen disease) operation or administration of antibiotics. Eight percent out of 91 organisms isolated from culture of catheter tips were so-called resistant strains; multi-drug resistant Staphylococci (16), Pseudomonas aeruginosa (5), fungi (49), etc. Complications (shock, acute renal failure, secondary pneumonia, fungal endophthalmitis) broken out in 18 patients (14.4% out of 125 CRS). Fungi were isolated from 14 out of 18 complicated cases, furthermore fungi were isolated alone in 11 cases. No complication were seen among cases from which gram positive cocci were isolated alone. Body temperature and white blood cell count of complicated cases were significantly higher than those of uncomplicated cases. The duration until removal of catheter from outbreak of fever in complicated cases was significantly longer than that in uncomplicated cases.

We report an exceptional case of fulminant endophthalmitis after uncomplicated extracapsular cataract extraction with posterior chamber lens implantation. The first unusual finding was the causative organisms, group G streptococci. These organisms are commonly found as normal flora of the skin, pharynx and gastrointestinal tract. They are also well known as pathogens of neonatal sepsis, otitis media and pneumonia, but there are only three case reports describing a streptococcus G endophthalmitis. The second unusual finding was the delayed onset of the fulminant endophthalmitis, occurring later than 9 days after surgery. A retrospective analysis of 17 additional cases showed that endophthalmitis occurred either during the first 5 days after surgery or later than 35 days after surgery. If endophthalmitis developed shortly after surgery it progressed rapidly and with intense inflammation. The other cases showed more chronic inflammatory reaction. From the latter finding we conclude that long postoperative monitoring remains necessary even if at first no signs of intraocular inflammation are detectable.

A 65-year-old woman with a 7-year history of chronic lymphocytic leukemia presented with acute visual loss, pain, and redness in her right eye. Results of stains and cultures of anterior chamber fluid were negative. Neurologic problems, bronchopulmonary pneumonia, recurrent skin lesions, and a low-grade fever developed. Progressive respiratory distress ensued, and the patient died 1 month after presentation. Cultures from antemortem sputum and skin samples were positive for Aspergillus terreus. Postmortem histologic results showed extensive A terreus invasion of the posterior vitreous, retina, choroid, and anterior optic nerve. This organism was also found in histologic sections from the right adrenal gland, left kidney, thyroid, urinary bladder, right lung, skin, esophagus, sputum, vessels of the myocardium, and brain. To our knowledge, A terreus endophthalmitis has not been reported previously.

For many years Branhamella catarrhalis was regarded as a non-pathogenic inhabitant of the respiratory tract. This article outlines the spectrum of B. catarrhalis disease in childhood and the extent of the evidence for a pathogenic role of the organism. B. catarrhalis is a rare etiologic agent in septicemia, meningitis, and other systemic illness in both apparently normal and immunocompromised infants and children. It is an unusual cause of ophthalmia neonatorum, but can be confused with Neisseria gonorrhoeae. Whether or not B. catarrhalis is acquired from the birth canal in these cases has not been established. B. catarrhalis is most common as a respiratory tract pathogen in children, including pneumonia, bacterial tracheitis, sinusitis, and otitis media. Since it is difficult to rigorously document pathogenicity of any bacterium in bronchopulmonary infections in children, it is probable that the spectrum of B. catarrhalis disease is wider than that reported to date. The evidence for pathogenicity in acute otitis media is more extensive than for other infections. Otitis media due to B. catarrhalis is clinically similar to that due to other pathogens. B. catarrhalis can be isolated in pure culture from the middle ear exudate and persists if there is no antibacterial treatment. Gram-negative intracellular and extracellular diplococci can be seen on smears of the inflammatory exudate. There is preliminary evidence that there is an antibody response in B. catarrhalis otitis media. B. catarrhalis has emerged as an important and common pathogen in neonates, infants, and children.

A case of metastatic Serratia marcescens (SM) endophthalmitis is described in a 57-year-old diabetic woman, after amputation of her leg above the knee because of peripheral vascular disease. SM cultured from the infected surgical stump was the source of septic emboli to her right eye and lungs, causing endophthalmitis and pneumonia. The ocular infection did not respond to appropriate antibiotic therapy and evisceration was required. SM infection can cause endophthalmitis refractory to antibiotics, and it should be aggressively treated when SM is cultured from any infected site.
