Meningococcal conjunctivitis in neonates.

Three neonates were admitted with purulent conjunctivitis, and an initial diagnosis of gonococcal ophthalmia was made because gram-negative diplococci were seen on gram stains of conjunctival exudates. Meningococci were grown from eye exudates of all three infants and from the blood of one. Since Neisseria species other than gonococci can sometimes cause neonatal ophthalmia, an etiologic diagnosis should not be made until microbiologic identification is complete. Before the results of definitive bacteriologic studies are known, care should be taken in discussing the cause of the infection with family members and in planning their medical management. Since systemic infections may occur in some infants with ophthalmia due to Neisseria species, blood and spinal fluid in addition to eye exudate cultures may be indicated, and patients should be managed with parenteral antibiotics.

Cataract extraction in the sympathizing eye.

Cataract extraction was performed on the sympathizing eyes of six patients with sympathetic ophthalmia. In five patients the clinical diagnosis of sympathetic ophthalmia was supported by the results of histologic examination of the exciting eye. The postoperative period averaged 12 years, and visual acuities ranged from 20/25 to light perception. The presence of posterior synechiae posed the major complicating operative factor. Cystoid macular edema, vitreous opacity, pupillary membrane formation, and corneal opacification were associated with postoperative visual impairment in four cases. We conclude that the underlying status of the sympathizing eye at the time of cataract extraction and postoperative management are critical factors that influence ultimate visual outcome.

Efficacy of neonatal ocular prophylaxis for the prevention of chlamydial and gonococcal conjunctivitis.

Opinions differ concerning the efficacy of prophylaxis against neonatal chlamydial and gonococcal conjunctivitis. From January 1986 through June 1988, we gave all infants born at Kings County Hospital Medical Center one of three prophylactic agents -- silver nitrate drops, erythromycin ophthalmic ointment, or tetracycline ophthalmic ointment. The treatments were rotated monthly. Gonococcal ophthalmia occurred in 8 of the 12,431 infants born during the study (0.06 percent), 1 in the silver nitrate group, 4 in the erythromycin group, and 3 in the tetracycline group (P not significant). Seven of these infants were born to women who had received no prenatal care. From September 1985 through December 1987, we screened 4357 pregnant women for cervical chlamydial infection, of whom 341 (8 percent) had positive cultures. Of their offspring, 230 were evaluated for neonatal chlamydial conjunctivitis; the incidence was 20 percent in the silver nitrate group, 14 percent in the erythromycin group, and 11 percent in the tetracycline group (P not significant). We conclude that neonatal ocular prophylaxis with either erythromycin or tetracycline ophthalmic ointment does not significantly reduce the incidence of chlamydial conjunctivitis in the offspring of mothers with chlamydial infection as compared with silver nitrate, and that better management of maternal chlamydial infection is therefore required. We also conclude that there is a small but appreciable incidence of neonatal gonococcal ophthalmia that could be prevented by better prenatal screening and treatment of maternal gonococcal infection.

Treatment of gonococcal conjunctivitis with a single intramuscular injection of cefotaxime.

Between 25% and 50% of children in African countries are exposed to Neisseria gonorrhoeae at birth and are at risk of developing gonococcal ophthalmia neonatorum. The problem is aggravated by the emergence of penicillinase-producing strains of N. gonorrhoeae (PPNG). Twenty-one children (9 boys, 12 girls, mean age 13 days) presenting with gonococcal conjunctivitis were identified during a 47-month period. Nineteen children received a single im injection of 100 mg/kg cefotaxime (maximum dose 1 g) without topical antibiotic therapy. One neonate with concurrent otitis media was treated with cefotaxime for five days and a 17-month old girl received two im injections because of the severity of her symptoms. Eight patients (38%) had received previous antibiotic therapy (penicillin im and/or tetracycline eye ointment). Twelve isolates of N. gonorrhoeae were found to be PPNG strains. At three to seven day follow-up examination all 21 patients were clinically cured without residual eye damage. Cefotaxime offers an effective first line treatment for gonococcal ophthalmia neonatorum in areas where there is a high prevalence of PPNG strains. The advantages of a single-dose treatment over multidose regimens in terms of compliance and cost are discussed.

Current status of Credé prophylaxis.

The time-honored practice of silver nitrate application to the eyes of newborns is compared to the use of antibiotics. Side effects, effectiveness, and clinical practicality in preventing ophthalmia neonatorum are considered. The inability of prophylactic agents to inhibit several serious pathogens that cause conjunctivitis of the newborn is a factor. Prenatal screening for venereal disease and close observation of the baby's eyes in the postpartum period are additional ways to decrease the incidence of ophthalmia neonatorum.

Branhamella catarrhalis conjunctivitis.

Eleven cases of Branhamella catarrhalis conjunctivitis have been reported. In four recent studies that examine the microbial etiology of ophthalmia neonatorum, B catarrhalis was identified only twice in 1,299 cases. However, diagnosis by Gram stain in some and previous antibiotic therapy in others may have resulted in underdiagnosis of B catarrhalis and inaccurate diagnosis as gonococcal ophthalmia.

Subclinical pneumonia due to serotypes D-K of Chlamydia trachomatis. Case reports of two infants.

Pneumonia due to serotypes D-K of Chlamydia trachomatis occurred in a 10-week-old baby, who had been successfully treated with chlortetracycline eye ointment for chlamydial ophthalmia neonatorum, and in a 7-week-old baby being treated for the same condition. Clinical signs of pneumonia were minimal. Such chlamydial pneumonia in infants must be under-diagnosed. Infants with chlamydial ophthalmia neonatorum are now routinely treated with erythromycin suspension by mouth in addition to chlortetracycline eye ointment.

The impact of national and international guidelines on newborn care in the nurseries of Piedmont and Aosta Valley, Italy.

BACKGROUND: Care procedures for preventing neonatal diseases are carried out according to nurseries' traditions and may be not consistent with the evidence based medicine issues. METHODS: A multi-centric survey was conducted in 2 Regions located in NW Italy (Piedmont and Aosta Valley) in order to collect information on some healthy newborn care procedures. During 2001, a questionnaire was sent to the chief pediatrician in charge to the all 33 nurseries of the region asking the methods used during 2000 as prevention of ophthalmia neonatorum, early and late hemorrhagic disease of newborn, umbilical cord care and recommendations of vitamin D administration. Thereafter, during 2004 the same questionnaire was sent to the 34 chief pediatrician of nurseries to evaluate if the procedures were changed during 2003 according to guidelines. The nurseries care for 32,516 newborns in 2000 and 37,414 in 2003. RESULTS: Aminoglycoside eyes drops as prevention of ophthalmia neonatorum were the first choice in both periods (23 out 33 nurseries in 2000 and 24 out 34 in 2003 p > 0.05; the corresponding figures for newborns were 18,984 out 32,516 newborns vs. 28,180 out of 37,414 p < 0.05). The umbilical cord care was carried out with alcohol in 12/33 centers (13,248 newborns) and dry gauze in 3/33 centers (2,130 newborns) in 2000, the corresponding figures in 2003 were 6/34 centers (p > 0.05), (6,380 newborns, p < 0.05) and 12/34 centers (p < 0.05), (18,123 newborns, p < 0.05). The percentage of newborns receiving of i.m. vitamin K. at birth increased during the study period (15,923/32,104 in 2000 vs. 19,684/37,414 in 2003, p < 0.01), but not the number of nurseries (16 in 2000 and 17 in 2003 p > 0.05). The numbers of parents of newborns who receive the recommendations of oral vitamin K during the first months life decreased from 2000 (25,516/30,606) to 2003 (29,808/37,414, p < 0.01) as well as for Vitamin D recommendation (14,582/30,616 in 2000 vs. 11,051/37,414 in 2003, p < 0.01). Oral vitamin K during the first months of life was recommended by 25 nurseries in 2000 and 27 in 2003 (p > 0.05), the corresponding figures for Vitamin D were 15 and 14 (p > 0.05). CONCLUSION: In the present study a large variability of procedures among the nurseries was observed. During the study periods, guidelines and evidence based medicine issues have only partially modified the neonatal care procedures In Piedmont and Aosta Valley nurseries. These observations suggest to implement local forum/consensus conference to standardized procedures as much as possible.

Human S-antigen determinant recognition in uveitis.

PURPOSE: Soluble antigen (S-Ag) is a member of the arrestin family of protein with which it shares a high level of homology. It is an immunologically privileged retinal antigen that can elicit experimental autoimmune uveitis (EAU) and is thought to be a target for ocular inflammatory diseases. This study was conducted to identify in humans, the immunogenic determinants of human S-Ag and to establish whether a specific response profile occurs in particular ocular inflammatory conditions. METHODS: Peripheral blood lymphocyte responses were measured against a panel of 40 overlapping synthetic peptides of human S-Ag in patients with chronic uveitis and compared with control subjects. Patients with Behçet disease, sarcoidosis, Vogt-Koyanagi-Harada, and sympathetic ophthalmia were tested. RESULTS: A limited number of immunodominant determinants were identified for Behçet disease and sarcoidosis. These were all located at sites of limited homology with other known arrestins. In addition, several individual patients had prominent proliferative responses to multiple determinants well above that of control subjects. This determinant spread was observed in all disease entities except sympathetic ophthalmia, which did not show any immunoreactivity to S-Ag. Significant response shifts were also noted over time in two patients. CONCLUSIONS: The results indicate that there are specific immunodominant determinants to human S-Ag in patients with certain forms of uveitis. However, in individual patients, response is not limited to these determinants. In the chronic stage of disease, response is spread over many determinants.

[Sexually transmitted diseases and mother-infant transmission (epidemiology and prevention)].

Gonococcal ophthalmia neonatorum may be severe with a high risk of blindness; therefore prophylaxis is mandatory. Chlamydial ophthalmia is less severe and prevention remains less effective. Both microorganisms may be responsible of preterm labour and perinatal deaths. Congenital syphilis is an important public health problem in developing countries. Some recent papers underline the decrease of infestation when mothers may be screened during pregnancy (at least two times in initially seronegative mothers) and correctly treated by beta-lactamines.

Gonorrhea in pregnancy and in the newborn.

Prevalence rates of gonorrhea in pregnancy range from 0.2 to 15 percent. Pharyngeal gonorrhea is more frequent in some prenatal populations. A degree of protection against pelvic inflammatory disease occurs in pregnancy, but there is an increased risk for disseminated gonococcal infection. Maternal gonococcal infection is associated with ectopic pregnancy, prematurity and ophthalmia neonatorum. Prompt and aggressive treatment is required for ophthalmia neonatorum.

Ocular findings following intravitreal silicone injection.

In three cases of intraocular silicone oil injection in which the histologic picture is observed at different time intervals, emphasis is given to the fact that fibrous tissue formation around silicone vesicles is a rather constant complication and of early occurrence. Thus, we believe that the removal of liquid silicone from the eye should not take place later than two or three months after the injection. In our first reported case, there was an association of silicone oil injection and vitrectomy with retinal detachment procedures and sympathetic ophthalmia. In the absence of evident histologic or clinical proof, we do not consider silicone oil injection itself as having induced the mechanisms of sympathetic ophthalmia.

The French Egyptian campaign and its effects on ophthalmology.

Almost all soldiers of the armies involved in the Egyptian campaign fell victim to what was later called the ophthalmia militaris which we now know to be caused by Haemophilus aegyptius, N. gonorrhoea and possibly to some extent by Chlamydia trachomatis but more likely by the adenoviruses. Because of the enormous incidence of ocular infection and the controversy generated by speculation on the nature of the disease--English surgeons considered this ophthalmia to be of a contagious nature, whereas the French surgeons violently opposed this view-, the interest in diseases of the eye increased, which eventually resulted in the acceptance of ophthalmology as a separate branch of medicine.

Pars plana lensectomy in cases of cataract with juvenile chronic uveitis.

BACKGROUND: Classical cataract extraction in young patients with secondary cataract following juvenile chronic uveitis often is complicated by serious problems such as severe postoperative uveitis, hypotonia oculi and phthisis bulbi. Lensectomy with partial anterior vitrectomy might be a less inflammatory way of handling these cases. METHODS: Over a 15-year period we have treated 10 eyes of 9 young patients (age from 8 to 30 years) with secondary cataract after chronic uveitis by pars plana lensectomy with partial anterior vitrectomy. A classical two-port technique was used with incisions at 4 mm from the limbus. The follow-up period varied from 3 to 12 years with an average of 8 years. There were five patients with chronic iridocyclitis, two with Fuch's heterochromic irridocyclitis, one with sympathetic ophthalmia and one with idiopathic panuveitis. RESULTS: Seven eyes were corrected with contact lenses. During the entire follow-up period six had 20/20 visual acuity and one, 20/40. None of these patients reported tolerance problems with the contact lens. One patient has 20/20 visual acuity with spectacles. One patient who initially had 20/20 visual acuity with a contact lens developed retinal detachment 2 years after surgery, during pregnancy, and now has 20/40 vision after retinal surgery. She prefers not to wear the contact lens any longer because of diplopia. The visual acuity of one patient was no better than hand movement and his aphakia was never corrected. Complications included one vitreous haemorrhage necessitating a second vitrectomy, one retinal detachment during pregnancy and one retinal detachment with proliferative vitreoretinopathy. One patient with sympathetic ophthalmia has 20/20 vision after 9 years' follow-up but still needs systemic steroids and cyclosporine. CONCLUSION: Pars plana lensectomy, with anterior vitrectomy appears to be a relative safe way to treat secondary cataract in patients during the first 30 years of life.

Functional outcome and prognostic factors in 304 eyes managed by retinectomy.

BACKGROUND: This study was undertaken to relate the anatomic and functional results of patients who underwent retinectomy for complex retinal detachment (RD) to preoperative prognostic variables. METHODS: Three hundred and four eyes of 302 patients whose surgery involved retinectomy were included in the analysis. All eyes had established proliferative vitreoretinopathy (PVR grade C). The main outcome measures were (1) postoperative visual acuity of 6/24 or better, (2) status of the retina at the end of follow-up, and (3) incidence of hypotony whilst under review. RESULTS: PVR was secondary to rhegmatogenous RD in 237 eyes (78%), posterior trauma in 51 eyes (16.8%), tractional RD in vasoproliferative vasculitides in 12 eyes (4%), acute retinal necrosis in 2 eyes and endophthalmitis in 2 eyes. Complete reattachment rate after one operation was 51%, with final complete reattachment success rate of 72%. The visual acuity improved in 138 eyes (45%), remained the same in 73 eyes (24%) and became worse in 89 cases (29%). Postoperative visual acuity of 6/24 or better was significantly associated with preoperative vision, the duration of silicone oil tamponade, silicone oil removal and retinectomy size. There was also some evidence of association between visual outcome and the number of clock hours of retinal detachment. Final retinal attachment was significantly associated with silicone oil removal and preoperative vision, and final hypotony was significantly associated with silicone oil removal. The incidence of sympathetic ophthalmia in our study was 0.09% (one case). CONCLUSIONS: Good functional outcome is possible following retinectomy surgery despite advanced pathology and often multiple surgical procedures. Retinal redetachment as a result of reproliferation and hypotony appear to be the main reasons for anatomical and functional failure. The clinical features we have identified as good indicators for improved final visual acuity such as shorter tamponade duration, removal of silicone oil, smaller retinectomy size, fewer previous operations and better preoperative vision are surrogate markers of less advanced PVR and should prompt retinal surgeons to consider retinectomy at an earlier stage in the process of PVR development. Clinicians should be aware of the small risk of sympathetic ophthalmia from complex retinal surgery.

FK506 treatment of noninfectious uveitis.

PURPOSE: We studied the clinical effects of the immunosuppressive agent FK506 in patients with noninfectious uveitis. METHODS: This study was designed as a multicenter open clinical trial in Japan. Sixteen patients with noninfectious uveitis who had visited the Uveitis Survey Clinic of the Yokohama City University Hospital were given FK506. Eight had Behçet's disease; five, Vogt-Koyanagi-Harada syndrome; one, sympathetic ophthalmia; one, retinal vasculitis; and one, sarcoidosis. In patients with Behçet's disease, ocular attack score before and after therapy was compared to judge clinical status. For the other diseases, the ocular inflammatory symptoms were observed after the initiation of FK506 treatment. All patients underwent blood and urine examinations, electrocardiography, and chest x-rays before and after FK506 treatment. RESULTS: Of the patients with Behçet's disease, five improved, one remained unchanged, one deteriorated, and the status of one could not be determined. Of the patients with Vogt-Koyanagi-Harada syndrome, four improved, and one remained unchanged. The patient with sympathetic ophthalmia improved, the patient with retinal vasculitis remained unchanged, and the status of the patient with sarcoidosis could not be determined. Major adverse effects were sensations of warmth, hypomagnesemia, renal dysfunction, glucose intolerance, nausea, vomiting, and disorders of the central nervous system. All adverse effects disappeared or improved when FK506 was stopped or when the dosage was decreased. Renal dysfunction and glucose intolerance appeared when the blood level of FK506 was high. CONCLUSIONS: FK506 was effective in patients with uveitis, but it is important to monitor the occurrence of adverse effects.

The in vitro antimicrobial capacity of human colostrum against Chlamydia trachomatis.

We sought to assess the antimicrobial capacity of human colostrum against Chlamydia trachomatis. a common agent of ophthalmia neonatorum. Colostrum was collected from 13 post-partum females and tested in an in vitro assay of chlamydial growth inhibition using HeLa 229 cells as the host cell line. All samples significantly inhibited chlamydial growth in a dose-response manner. The percent inhibition ranged from 45.3 to 99.0 (mean=88.1+/-4.1). The chlamydial growth inhibition activity of colostrum was found to be: heat- and freezing-resistant: more concentrated in colostrum than breast milk; was not attributable to interferon or antibody activity; and, could not be attributed to host cell cytotoxicity. Additionally, chlamydial growth inhibition occurred in < or = 15 min and was effective only when colostrum was incubated with chlamydiae prior to addition to HeLa 229 monolayers. Lastly, centrifugal fractionation of the colostrum yielded similar activity in the lipid pellicle and in the lipid-free supernatant. These results indicate that topically applied colostrum may have efficacy in the prophylaxis of ophthalmia neonatorum of chlamydial etiology in the absence of conventional modalities.
