Is Ophthalmia Neonatorum Associated With Invasive Bacterial Infection? A Single-Center Retrospective Study.

OBJECTIVE: Ophthalmia neonatorum (ON) is a conjunctivitis occurring in neonates and can be caused by multiple bacterial pathogens. The risk of invasive bacterial infection (IBI) in neonates with ON is poorly known. Our objectives were to document the association of ON with IBI in term neonates and to investigate practice variation. METHODS: This was a retrospective observational study of all neonates who presented to a single emergency department (ED) between January 2018 and December 2019. Participants were all children with a final diagnosis of ON according to the treating physician as registered in the ED computerized database. Newborns with craniofacial malformations and premature infants were excluded. The primary outcome was IBI as defined by growth of any bacterial pathogen in the blood or cerebrospinal fluid. Perinatal risk factors, ED visit details (symptoms on presentation, management, and treatment plan) as well as complications (ocular morbidity, death, and unscheduled return visits) were collected. Data were analyzed using descriptive statistics. RESULTS: Fifty-two term neonates were included. There were no cases of IBI associated with ON (0%; 95% confidence interval [CI], 0%-6.9%). Six ocular bacterial infections were identified, one of which was Chlamydia trachomatis . Although there were no IBIs, ocular complications, deaths, or unscheduled return visits to the ED, there was a wide variation in physician's management of ON. Physicians ordered investigations in 49% (95% CI, 34%-62%) of neonates, prescribed antibiotics to 87% (95% CI, 74%-94%), and involved specialists in 39% (95% CI, 27%-52%) of cases. CONCLUSIONS: Emergency department presentations of term neonates with ON are associated with a low risk of IBI. A better understanding of the current practice variation is needed to inform clinical guidelines for the management of neonates with ON presenting to the ED.

Antibiotic prophylaxis for ophthalmia neonatorum in Italy: results from a national survey and the Italian intersociety new position statements.

BACKGROUND: Ophthalmia neonatorum is an acute conjunctivitis that occurs in newborns within the first month of life. The most serious infections are due to Chlamydia trachomatis and Neisseria gonorrhoeae, that may cause permanent damages. The use of ophthalmic prophylaxis varies widely around the world, according to the different health and socio-economic contexts. To date in Italy there is no a clear legislation regarding ophthalmia neonatorum prophylaxis at birth. METHODS: We invited all birth centers in Italy to carry out a retrospective survey relating the last three years. We collected data regarding demographics of neonates, drugs used for ophthalmic prophylaxis and results of the screening of pregnant women for Chlamydia trachomatis and Neisseria gonorrhoeae vaginal infections. RESULTS: Among 419 birth centers, 302 (72,1%) responded to the survey. Overall 1041384 neonates, 82,3% of those born in the three years considered, received ophthalmic prophylaxis. Only 4,585 (0,4%) of them received one of the drugs recommended by the WHO. The Centers that participated to the survey reported 12 episodes of Chlamydial conjunctivitis and no Gonococcal infection in the three years. Only 38% of the Centers performed vaginal swabs to pregnant women: 2,6% screened only for Neisseria, 9,6% only for Chlamydia and 25,8% for both germs. CONCLUSIONS: The data obtained from the survey showed a low incidence of neonatal conjunctivitis due to either Neisseria gonorrhoeae or Chlamydia trachomatis in Italy. Due to the lack of legislation regulating the prophylaxis of ophthalmia neonatorum in newborns, the Italian Society of Neonatology, the Italian Society of Obstetrics and Gynecology and the Italian Society of Perinatal Medicine have recently issued new recommendations on this topic.

Case series and literature review of chlamydial ophthalmia neonatorum in Botswana.

BACKGROUND: We describe 12 cases of chlamydial ophthalmia neonatorum and the current scientific evidence on its prevention and treatment. The data presented were obtained from the "Maduo" study, a prospective observational study of the relationship between curable sexually transmitted infections and adverse neonatal outcomes at four antenatal clinics in Gaborone, Botswana. METHODS: Infants of mothers with perinatal chlamydia infection were evaluated for chlamydial ophthalmia neonatorum based on clinical presentation of conjunctivitis or positive test via GeneXpert CT/NG assay. Data on 29 infants born to mothers with postnatal C. trachomatis infection were analysed. RESULTS: 12 infants were diagnosed with chlamydial ophthalmia neonatorum. Eight of those cases were confirmed with the GeneXpert CT/NG assay while four were identified as probable cases based on clinical history and presentation. Overall, nine infants presented with signs of conjunctivitis, while three who had a positive diagnostic test result had asymptomatic infection. All but one infant had received ocular 1% tetracycline prophylaxis at birth, and four infants had signs suggestive of chlamydial pneumonia at presentation. Two out of five symptomatic cases whose mothers reported completion of their treatment course with erythromycin had lingering symptoms. CONCLUSIONS: Our findings affirm that the current prophylaxis and treatment modalities for chlamydial ophthalmia neonatorum are inadequate. To the extent feasible in low- and middle-income countries, we recommend implementation of routine C. trachomatis screening and treatment in pregnant women.

Universal ophthalmia neonatorum prophylaxis in Ontario: a cost-effectiveness analysis.

BACKGROUND: Although prophylaxis for ophthalmia neonatorum at birth is required by law in Ontario, declining prevalence of disease and efficacy of prophylaxis have called this practice into question. The objective of this modelling study was to assess the cost-effectiveness of universal prophylaxis for ophthalmia neonatorum to inform decision-makers on the potential impact of a change in this policy. METHODS: We compared the cost-effectiveness of prophylaxis for ophthalmia neonatorum with no prophylaxis through cost-utility analysis with a lifetime time horizon, considering a provincial government payer, for a hypothetical population of newborns in Ontario. We assessed both the mean incremental costs of prophylaxis and its mean incremental effectiveness using a hybrid (part decision tree, part Markov) model. We used a scenario analysis to evaluate alternative time horizons and discount rates. We conducted a threshold analysis to evaluate the impact of variations in the cost of prophylaxis and in the prevalence of sexually transmitted infections (gonorrhea and chlamydia). RESULTS: In our model, prophylaxis for ophthalmia neonatorum did not meet a willingness-to-pay threshold of Can$50 000 per quality-adjusted life-year (QALY). Although prophylaxis was effective in reducing morbidity associated with ophthalmia neonatorum, the number needed to treat to prevent 1 case of ophthalmia neonatorum blindness was 500 000, with an associated cost of more than Can$4 000 000. When compared with no prophylaxis, prophylaxis had an incremental cost of Can$355 798 per long-term QALY gained (incremental cost-effectiveness ratio). INTERPRETATION: We found that prophylaxis for ophthalmia neonatorum, although individually inexpensive, leads to very high costs on a population level. These findings contribute to the discussion on mandatory prophylaxis currently underway in several jurisdictions.

Neonatal ocular prophylaxis in the United States: is it still necessary?

INTRODUCTION: Much has changed since Credé reported that silver nitrate decreases the incidence of ophthalmia neonatorum. Prenatal screening and treatment of pregnant women for Neisseria gonorrhoeae became standard in the 1950s and for Chlamydia trachomatis in 1993. Neonatal gonococcal and chlamydial conjunctivitis are consequently uncommon today. Currently, only 0.5% erythromycin ophthalmic ointment is available in the United States (U.S.) for neonatal ocular prophylaxis, which is ineffective against C. trachomatis. AREAS COVERED: This article addresses the altered epidemiology of ophthalmia neonatorum in the U.S. since prophylactic practices began, the lack of data supporting ophthalmic erythromycin for prevention of neonatal gonococcal and chlamydial conjunctivitis, and the impact of prenatal screening and treatment of pregnant women for N. gonorrhoeae and C. trachomatis on conjunctivitis incidence. The authors discuss why erythromycin ophthalmic ointment is likely ineffective against gonococcal ophthalmia, including the development of macrolide resistance. Physiologic limitations and pharmacokinetic properties are considered with respect to ophthalmic erythromycin for the prevention of gonococcal and chlamydial conjunctivitis. EXPERT OPINION: Administration of erythromycin ophthalmic ointment for the prevention of neonatal conjunctivitis is not literature-supported. Prenatal screening and treatment of pregnant women is the most effective way to prevent ophthalmia neonatorum. National mandates for prophylaxis should be withdrawn.

Ophthalmia neonatorum in a tertiary referral children's hospital: A retrospective study.

OBJECTIVES: The purpose of this study was to examine the aetiology, investigation and management of ophthalmia neonatorum (ON) presenting to a tertiary referral children's hospital over 5 years. METHODS: The eye swab data of all neonates presenting to Children's Health Ireland at Temple Street (Dublin, Ireland) between 1st January 2013 and 3rd September 2018 was analysed. The medical records of all patients with positive eye swab results were retrospectively reviewed. RESULTS: A total of 157 neonates had positive eye swab results. 54 cases were identified as ON. Chlamydia trachomatis (20.4%) was the most common organism identified, followed by Staphylococcus aureus (18.5%), Haemophilus influenzae (14.8%), Moraxella catarrhalis (7.4%), Streptococcus pneumoniae (5.6%), Escherischia coli (3.7%), Klebsiella pneumoniae (1.9%) and Pseudomonas aeruginosa (1.9%). A bacterial culture swab was tested in all cases (100%), a C. trachomatis/N. gonorrhoeae PCR swab in 70.4% and a viral PCR swab in 35.2%. On subanalysis of the cases that had C. trachomatis/N. gonorrhoeae PCR testing, C. trachomatis was responsible for 28.9% of cases. 50% of cases were hospitalised, intravenous antibiotics were administered in 46.3% and macrolide therapy was prescribed in 38.9%. CONCLUSIONS: C. trachomatis was the most common cause of ON in this study and may be responsible for an even higher proportion of cases due to incomplete testing. In keeping with studies in different populations, S. aureus, H. influenzae and S. pneumoniae were also common. As a result, an improved management algorithm for cases of ON has been introduced in this centre.

Culture Positive Cases of Ophthalmia Neonatorum in a Tertiary Care Centre of Nepal: A Descriptive Cross-sectional Study.

INTRODUCTION: Ophthalmia neonatorum although runs a benign course mostly, sometimes may progress to sight threatening complications. The study was conducted to find the prevalence of culture positive cases of opthalmia neonatorum. METHODS: It was a descriptive cross-sectional study conducted at a tertiary care center from January to December 2019. Ethical clearance was obtained from institutional review committee of Kathmandu Medical College. Convenience sampling was done. All data were entered into excel and, then for analysis, exported to Statistal Package for Social Sciences version 21. Point estimate at 95% Confidence Interval was calculated along with frequency and proportion for binary data. RESULTS: The prevalence of culture positive cases of opthalmia neonaturum is 10 (55.55%) (32.61-78.49 at 95% Confidence Interval). The causative organisms were coagulase negative Staphylococcus 4 (40%), Staphylococcus aureus 3 (30%), Klebsiella 2 (20%) and Pseudomonas 1 (10%). Culture sensitivity of the isolated organisms were different according to the patient even in case of the same organism. Vancomycin 7 ( 70%) was the most sensitive antibiotic followed by Ciprofloxacin 6 (60%), Amikacin 5 (50%) and Cloxacillin 5 (50%) while Azithromycin 1 (10%), Cefixime 1 (10%) and Cotrimoxazole 1 (10%) were the least sensitive. CONCLUSIONS: Staphylococcus species was the most common organism isolated from neonates with ophthalmia neonatorum and vancomycin was the most sensitive antibiotic.

Gonococcal infection: An unresolved problem. / Infección gonocócica: un problema aún sin resolver.

Gonococcal infection is a current public health problem worldwide, being the second most prevalent bacterial sexually transmitted infection. The etiologic agent is Neisseria gonorrhoeae, a gram-negative diplococcus, and mainly causes urethritis in men. In women up to 50% of infections can be asymptomatic. N. gonorrhoeae has a great ability to develop antibiotic resistance, so the last remaining therapeutic option are extended spectrum cephalosporins. Many guides recommend dual therapy with ceftriaxone and azithromycin, but in recent years the resistance to azithromycin is also increasing, so that dual treatment is being questioned by scientific societies.

Ocular Prophylaxis for Gonococcal Ophthalmia Neonatorum: US Preventive Services Task Force Reaffirmation Recommendation Statement.

IMPORTANCE: In the United States, the rate of gonococcal ophthalmia neonatorum was an estimated 0.4 cases per 100 000 live births per year from 2013 to 2017. Gonococcal ophthalmia neonatorum can cause corneal scarring, ocular perforation, and blindness as early as 24 hours after birth. In the absence of ocular prophylaxis, transmission rates of gonococcal infection from mother to newborn are 30% to 50%. OBJECTIVE: To reaffirm the US Preventive Services Task Force (USPSTF) 2011 recommendation on ocular prophylaxis for gonococcal ophthalmia neonatorum. EVIDENCE REVIEW: The USPSTF commissioned a reaffirmation evidence update to identify new and substantial evidence sufficient enough to change its prior recommendation. FINDINGS: Using a reaffirmation process, the USPSTF found no new data that would change its previous conclusion that topical ocular prophylaxis is effective in preventing gonococcal ophthalmia neonatorum and related ocular conditions. The USPSTF found no new data that would change its previous conclusion that there is convincing evidence that topical ocular prophylaxis of all newborns is not associated with serious harms. Therefore, the USPSTF reaffirms its previous conclusion that there is convincing evidence that topical ocular prophylaxis for all newborns provides substantial benefit. CONCLUSIONS AND RECOMMENDATION: The USPSTF recommends prophylactic ocular topical medication for all newborns to prevent gonococcal ophthalmia neonatorum. (A recommendation).

Neonatal conjunctivitis in the New Zealand Midland region.

AIMS: To assess the incidence of chlamydial and gonorrhoeal neonatal conjunctivitis (CON and GON), across six district health boards in the greater Midland region of New Zealand. METHODS: All positive nucleic acid amplification test (NAAT) eye swabs for Chlamydia trachomatis and NAAT and bacterial eye swabs for Neisseria gonorrhoeae in infants under one year of age were retrieved from three laboratories from 2013-2016. Incidence density rates were calculated using births information from Statistics New Zealand. A subgroup analysis of Waikato and Tairawhiti cases were further analysed. RESULTS: Calculated rates for the Greater Midland region are CON, 145.9 per 100,000 births/year and GON, 3.79 per 100,000 births/year. For Tairawhiti and Waikato, the incidence of CON is 2.5 times greater in Maori than non-Maori (95% CI 1.3-5.1, P<0.01). There was no significant difference in mean NZDep13 for Maori vs non-Maori. Mean maternal age at birth was 20. CONCLUSIONS: Greater Midland region rates of CON and GON are higher compared to other international reported rates. For Tairawhiti and Waikato, rates of CON are significantly higher in Maori than non-Maori, although there is no difference in mean NZDep13 scores between Maori and non-Maori. CON appears to be a condition of babies of young mothers with higher deprivation.

A chronological study of the bacterial pathogen changes in acute neonatal bacterial conjunctivitis in southern China.

BACKGROUND: The aim of the project is to retrospectively study the changes in bacterial pathogens in acute neonatal bacterial conjunctivitis from 2002 to 2016 in Southern China. The results may provide the guidance for drug choice for acute neonatal bacterial conjunctivitis. METHODS: Secretion specimens for bacterial culture were taken from 485 cases with clinically diagnosed acute bacterial neonatal conjunctivitis. Bacterial pathogens were detected by Gram staining and subsequent bacterial culture. RESULTS: From the analysis of the bacterial pathogens in 485 cases of acute neonatal conjunctivitis patients from 2002 to 2016 in Southern China, there is an overall trend of decreasing detection of Gram-positive bacteria and increasing detection of Gram-negative bacteria from the conjunctival sac secretions. Gram-positive bacteria in the bacteria-positive samples dropped year by year from 82.6% in 2002 to 72.4% in 2016. Accordingly, the ratio of Gram-negative bacteria increased from 17.4% in 2002 to 27.6% in 2016. Of note, despite the overall trend, there was a significant increase in detection of Gram-positive bacteria and decrease in detection of Gram-negative bacteria from 2011 to 2012. Among the Gram-positive bacteria, there is a trend of increasing percentage of the opportunistic pathogens (an ~60% increase in Staphylococcus epidermidis and Staphylococcus saprophytic) and decreasing percentage of Staphylococcus aureus (~30% decrease) and hemolytic streptococcus (~20% decrease) in the last 15 years. The main Gram-negative bacterium is Neisseria gonorrhoeae. Overall, there is a change in the pattern of bacterial species in acute neonatal bacterial conjunctivitis in Southern China in the last 15 years. CONCLUSION: Our study provides a trend analysis of the bacterial pathogens in the conjunctival sac secretions of the acute neonatal bacterial conjunctivitis patients in Southern China in recent years. This data could provide useful information regarding the treatment options for neonatal bacterial conjunctivitis.

Keeping an Eye on Chlamydia and Gonorrhea Conjunctivitis in Infants in the United States, 2010-2015.

Perinatal transmission of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) can result in conjunctivitis in infants. We examined national rates of reported CT/GC conjunctivitis among infants. Surveillance of these infections is heavily affected by the completeness of reported data on specimen source and age. Alternative data sources should be evaluated.

Ophthalmia neonatorum treatment and prophylaxis: IPOSC global study.

INTRODUCTION: Characteristics of ophthalmia neonatorum (ON) amongst paediatric ophthalmologists remain unclear. The purpose of this current study is to examine the incidence, diagnosis, treatment, and prophylaxis of ON cases presenting to members of the American Association of Paediatric Ophthalmology and Strabismus (AAPOS). METHODS: An email containing a web link to a survey was sent to all members of AAPOS. The questionnaire examined the incidence of ON, etiology, diagnostic methods, treatment, and prophylaxis of the disease in different countries around the world. RESULTS: Two hundred and ninety-one ophthalmologists answered the questionnaire. Most were from North America (52.94 %). One hundred and seventy-six (60.69 %) ophthalmologists encountered 0-5 cases of ON per year. The most common pathogens causing ON was Chlamydia trachomatis (35.37 %). Two hundred and forty-two (85.21 %) treat empirically when encountering ON during the first 10 days of life and 205 (75.09 %) after the first 10 days of life. In both cases, erythromycin was the most common first line of treatment. Two hundred and twenty-two (78.72 %) ophthalmologists replied that prophylactic treatment is required in their country. The most common agent for prophylaxis was erythromycin ointment (71.50 %). CONCLUSIONS: We found that the incidence of ON per year per practitioner is 0-5 cases, the most common etiology is C. trachomatis, and most infants receive prophylaxis and treatment.

Erythromycin Prophylaxis for Neonatal Conjunctivitis: Ointment Versus Drops.

BACKGROUND: Due to a shortage of individualized erythromycin ointment (IEO), we switched to shared erythromycin drops (SED). Following this change, nurses claimed observing more cases of eye discharge. OBJECTIVES: To test whether switching from IEO to SED affected the rate of neonatal conjunctivitis (NC). METHODS: The study group included 14,916 neonates > 35 weeks of gestation, further divided into two birth periods of 12 months each: 1 January 2013 to 31 December 2013 (IEO) and 1 February 2014 to 31 January 2015 (SED). We compared the two birth periods with regard to three variables: clinical NC (number of conjunctival swabs/1000 neonates), bacterial NC (number of culture-positive swabs/1000 neonates), and bacterial growth percentage (number of culture-positive swabs/100 samples). RESULTS: Compared to 2012-2013, the period 2014-2015 included fewer cesarean deliveries and shorter length of stay (LOS). Clinical NC, bacterial NC and bacterial-growth percentage were not different between the two periods. Variables that were independently significantly associated with increased clinical NC included male gender (OR 1.48, CI 1.21-1.81) and LOS (OR 1.24, CI 1.18-1.29). LOS was associated with bacterial NC (OR 1.19, CI 1.11-1.28). Coagulase-negative staphylococci, Escherichia coli and Pseudomonas aeruginosa were the prevalent pathogens, though without difference between periods. CONCLUSIONS: Rates of clinical NC, bacterial NC and bacterial-growth percentage were not different between the study periods. Switching from IEO to SED had no effect on the NC rate.

Prevalence of gonococcal conjunctivitis in adults and neonates.

PURPOSE: To report the prevalence of gonococcal conjunctivitis (GC) presenting to a tertiary referral maternity hospital (NMH) and a tertiary referral ophthalmic hospital (RVEEH) from 2011 to 2013 and describe the demographics, clinical presentation, and antibiotic susceptibility of Neisseria gonorrhoeae ocular infections. METHODS: Demographic, clinical, and microbiological data were collected from patients with laboratory confirmed GC. RESULTS: There were 27 556 live births at NMH during the study period, and no case of neonatal GC was identified. Fourteen cases of GC were identified at RVEEH in this period, representing a prevalence of 0.19 cases per 1000 eye emergency attendees. Antibiotic susceptibility data were available on nine cases, of which, all were ceftriaxone- and ciprofloxacin sensitive. 64.3% of patients were male, with a mean age of 18 years. The mean duration of symptoms was 3 days. All patients presented with unilateral conjunctival injection and purulent discharge. Eight cases had visual impairment at presentation and their mean visual acuity was 6/15. Corneal involvement was present in 25% of patients. Uveitis was not detected. On receipt of positive culture and/or PCR results, treatment was altered in two thirds of patients. All patients were referred for full STI screening and all patients showed a full clinical recovery 1 week posttreatment. CONCLUSION: We observed that GC presented in young adults with a male predominance and was rare in neonates. In cases of unilateral purulent conjunctivitis, there should be a high clinical suspicion of GC, early swab for PCR and culture, and knowledge of current CDC-recommended antibiotic guidelines.

Time trends in ophthalmia neonatorum and dacryocystitis of the newborn in England, 2000-2011: database study.

AIMS: To investigate English national trends in ophthalmia neonatorum and dacryocystitis (ON) of the newborn and the completeness of statutory notification of this serious infection. DESIGN: Analysis of hospital episode statistics (HES) from 2000 to 2011. MATERIALS AND METHODS: Using linked HES, numbers of neonates hospitalised with ON were identified from 2000 to 2011. The numbers of hospitalised cases were compared with numbers of statutory notifications for ON published by the Notifications of Infectious Diseases (NOIDS). RESULTS: The national incidence rate of hospitalised cases showed a gradual decline from 464 (95% CI 447 to 482) per 100,000 live births in 2000 to 216 (204 to 228) per 100,000 live births in 2005. It then gradually increased to 471 (455 to 487) per 100,000 live births in 2010, but dropped to 257 (245 to 269) per 100,000 in 2011. From 2000 to 2009, when NOIDS data were available, the NOIDS data showed only 1006 cases compared with 20,505 cases in HES, and thus the notification system captured only about 1 case in 20. CONCLUSIONS: As shown by hospital statistics, there were marked cyclical fluctuations in ON over the study period. The annual figures for ON reported during the study period, under statutory health protection regulations, underestimated the actual occurrence of this disease by a very substantial amount. Linked hospital data should be used routinely to monitor the national incidence of ON.

Prevalence of Chlamydia trachomatis among asymptomatic women.

BACKGROUND: Chlamydia trachomatis is a ubiquitous pathogen worldwide and causes ocular. urogenital, and respiratory infections in humans. C. trachomatis infection of lower genital tract is one of the most prevalent sexually transmitted diseases (STDs) in different parts of the world. Their treatment, follow-up, and hopefulness for future is very important. Objectives of this study were to see the prevalence of Chlamydia trachomatis infection among women of child bearing age and to determine the incidence of Chlamydia infection in neonates of women infected with Chlamydia. METHODS: This observational study was carried out in Department of Obstetrics & Gynaecology, CMH Abbottabad, and Department of Ophthalmology, Women Medical College Abbottabad from January 2012 to June 2012. Urine samples were collected from 200 women aged 20-39 years attending Obs/Gyn Department of CMH Abbottabad. After delivery, babies who were born to mothers with infection of their genital tracts were examined with a 2.5 x binocular loupe within a week of birth to rule out eye infection (Chlamydia Ophthalmic neonatorum). RESULTS: The overall prevalence of Chlamydia trachomatis was 4% in 200 eligible patients. The overall incidence of Chlamydia trachomatis in neonates was 1.66%. CONCLUSION: A significant proportion of women resident of Abbottabad District expressed evidence of exposure to Chlamydia trachomatis and significant number of neonate eyes were infected with the pathogen.

[What remains today of neonatal conjunctivitis in prefecture of Kozah in Togo?]. / Que reste-t-il aujourd'hui des conjonctivites néonatales dans la préfecture de la Kozah au Togo ?

AIM: The purpose of this study is to screen the neonatal conjunctivitis in order to evaluate its incidence and especially to seek for the causative germs. PATIENTS AND METHODS: We have realized cross-sectional study in three health centers of the prefecture of Kozah from March 24 to May 12, 2009. All the newborns followed in these centers are examined in the search of signs of conjunctivitis. A biological diagnosis of conjunctival secretions was carried out at the suspect newborns. RESULTS: During the study period, 348 newborns were examined including 185 boys and 163 girls corresponding to a sex-ratio (M/F) of 1.1. The middle age was 3.7 days. Twenty-eight newborns presented conjunctivitis, that is to say a rate of incidence of 8%. The cases of conjunctivitis were observed the first four days of life in 39.3% of cases. Eighteen of the newborns presenting conjunctivitis were vaginal deliveries (64.3%) against ten (35.7%) by caesarian. All the mothers of the ill newborns had a syndrome of sexually transmissible infection (STI) during the third quarters of pregnancy. After biological diagnosis, Staphylococcus aureus was found in 25% of the cases. CONCLUSION: Despite the common herd of neonatal conjunctivitis prophylaxis by Crede's method, its remains in the prefecture of Kozah. In hope for neonatal conjunctivitis eradication, treatment of STI on pregnant women associated to education and communication on the prevention of the infection in neonatal health care centers and at home by hygiene rule application are necessary.

Efficacy comparison between povidone iodine 2.5% and tetracycline 1% in prevention of ophthalmia neonatorum.

PURPOSE: To evaluate the efficacy of povidone iodine solution 2.5% and tetracycline ointment 1% in prevention of ophthalmia neonatorum (ON). DESIGN: Prospective, randomized, controlled observational study. PARTICIPANTS: Three-hundred ninety-four full-term neonates. METHODS: A randomized comparison between 201 neonates randomly treated with povidone iodine 2.5% solution and 193 treated with tetracycline 1% ointment. MAIN OUTCOMES MEASURES: Incidence of ON. RESULTS: The incidence of ON was significantly higher after povidone iodine than tetracycline prophylaxis (15.4% and 5.2% respectively; P = 0.001). Noninfective ON developed in 10 (5%) of the 201 neonates treated with povidone iodine and in none (0%) of the neonates treated with tetracycline (P = .002). Infective ON was detected in 21 (10.4%) of the neonates treated with povidone iodine and in 10 (5.2%) after treatment with tetracycline (P = .052). Ophthalmia neonatorum appeared more commonly in the first 3 days after treatment with povidone iodine (P = .043). The spectrum of the infective isolates was similar in the 2 groups. CONCLUSIONS: Povidone iodine was associated with noninfective (sterile) conjunctivitis, probably because of its toxicity to the ocular surface in neonates. Tetracycline was marginally more effective against infective ON. For these reasons, tetracycline, rather than povidone iodine, is recommended for prevention of ON.

What have we learned from sexually transmitted infection research in sub-Saharan Africa?

Many of the most important research findings on STIs in the past 30 years have come from sub-Saharan Africa. African researchers and their international collaborators have led the way in the development and validation of syndromic STI management, in furthering our understanding of the interactions between HIV and other STIs, in the development of evidence-based strategies for the control of HIV and other STIs in high risk groups and in the general population, and in clinical, microbiological and epidemiological studies on syphilis, chancroid and ophthalmia neonatorum. This review summarises the major achievements of STI researchers in Africa in the past 30 years, and discusses the reasons underlying the success of STI research in Africa.
