The data were provided by a search in the National Statistical Service of Greece (NSSG), and covered the period from January 1, 1979 through December 31, 1987, for all infant deaths in Greece. Data on live births were taken from the annual statistical reports of NSSG. Statistical analysis was done by means of the Edward's method. The seasonal patterns of the number of deaths and death rates (per 1000 live-born) were almost identical for the 2 parts of the period studied, for the years 1979 and 1987. 1979-83 and 1984-87 were treated separately for the neonatal period and for the postneonatal period. The number of neonatal and early neonatal deaths did not show significant seasonality in the total period, in either the urban or the rural areas, although the peaks for early neonatal deaths in 8 out of 9 studied years were in the spring and summer. The maximum number of postneonatal deaths was observed during January-February, representing a 60-90% increase compared to the minimum number of deaths, and the difference was more evident in the rural areas of residence in 1979-83. Neonatal deaths from prematurity showed statistically significant seasonal variation with a peak in May, more prominent in urban areas. Postneonatal deaths from infections showed statistically significant seasonal variation with a peak in February more prominent in rural areas and in the 1979-83 period. Postneonatal deaths from pneumonia showed very significant seasonal variation, with a peak in February more prominent in rural areas and in the 1979-83 period. Neonatal deaths from sepsis showed increased occurrence in May, whereas postneonatal deaths from sepsis and from enteric infections did not show significant seasonality. Deaths from injuries showed a statistically significant peak during January-February, in both urban and rural areas, in the postneonatal period. Neonatal and postneonatal deaths from sudden infant death syndrome were more common during the winter (December-January-February) in urban areas.

Growth of > or = 10(5) colonies of bacteria per milliliter obtained at bronchoscopy in children and adults correlates with bacterial pneumonia. To determine whether quantitative tracheal aspirate cultures aid in diagnosis of pneumonia in the neonatal intensive care unit setting, tracheal aspirates were obtained from 25 infants who had recently undergone endotracheal intubation; 15 of the infants had suspected pneumonia and 10 control infants had undergone intubation for suspected apnea of prematurity (4 infants) or elective surgery (6 infants). Studies also were performed to detect Mycoplasma, Ureaplasma, viruses, and Pneumocystis. Tracheal aspirates from 2 of 15 infants with suspected pneumonia grew > or = 10(5) bacteria, and 1 was positive for respiratory syncytial virus. These infants were considered to have pneumonia. In 12 infants whose tracheal aspirates grew < 10(5) bacteria, respiratory decompensation later was explained by other causes in 11 infants, and there was one false-negative culture. There were three false-positive tracheal aspirates in the control group. We conclude that tracheal aspirates of infants who have recently had an endotracheal tube placed may be useful for diagnosing pneumonia and for identifying the causative agent.

A household survey of neonatal mortality was conducted during 1991 in Meerut District, about 70 km from Delhi in Uttar Pradesh, India. The sample included 2211 infants from 30 clusters, which included 111 deaths in the first year of life for data collected during November 12-19, 1991. The estimate of infant mortality rate was 50.1/1000 live births. There were 42 neonatal deaths--a neonatal rate of 19.0/1000 live births. 90.5% of neonates were home deliveries. 45.3% were delivered by an untrained birth attendant and 30.9% were delivered by a trained birth attendant. 11.9% were delivered by a family member. 42.8% of neonates who died did not receive treatment for an illness before their death. 11.9% of neonates, who died but received some treatment, were treated in hospitals. 66.7% of mothers had knowledge about prenatal immunization against tetanus, but only 30.9% received complete immunization, and 23.8% had one dose of tetanus toxoid vaccine. The most common causes of death were attributed to septicemia and neonatal tetanus infections (21.4% of neonatal deaths). Other causes of neonatal death were infantile diarrhea (11.9%), prematurity (9.5%), congenital anomalies (9.5%), pneumonia (7.2%), and birth asphyxia, meningitis, burn injury, and Rh incompatibility (2.4% each). This study in 1991 shows that neonatal mortality declined over the prior 10 years. However, outreach of qualified medical staff into this rural community was still limited. Knowledge of some health practices, such as immunization, was evident, but the service component was inadequate. This study confirms that exogenous factors contributed to at least 66% of neonatal deaths. These deaths could have been averted with proper and timely maternal and child health care services.

Recent studies show an association between the presence of Ureaplasma urealyticum in tracheal aspirates and bronchopulmonary dysplasia. We hypothesized that among infants with birth weights < or = 1,250 g and respiratory disease, those with U. urealyticum in their tracheal aspirates would have radiographic evidence of more-severe pulmonary disease more often than would those without this organism. A total of 292 low-birth-weight infants who had endotracheal aspirate cultured within 7 days of birth were enrolled. The radiographic outcome variables were pneumonia, early severe bronchopulmonary dysplasia (precocious), and chronic lung disease. Microorganisms were isolated from 128 infants (44%); U. urealyticum was isolated from 44 (15%). Pneumonia was significantly more common in infants with than without U. urealyticum (30% vs. 16%, P = .03). U. urealyticum also was associated with precocious bronchopulmonary dysplasia independent of prematurity, race, and sex (odds ratio, 2.2; P < .05). Tracheal isolation of U. urealyticum within 7 days of birth is associated with pneumonia and precocious bronchopulmonary dysplasia.

Appreciation of Ureaplasma urealyticum as a human pathogen and documentation of antibiotic resistance have heightened interest in susceptibility testing and treatment alternatives. Treatment of neonates poses special problems because of potential drug toxicity, clinical unfamiliarity with the various conditions that may be due to or associated with ureaplasmal infection, and frequent isolation of the organism from mucosal surfaces in the absence of overt illness. Case reports have undeniably demonstrated the ability of U. urealyticum to cause neonatal bacteremia, pneumonia, and meningitis, although the frequency with which such clinically significant infections occur among the greater population of colonized neonates is unknown. The association of U. urealyticum with development of chronic lung disease of prematurity further intensifies the need for knowledge concerning effective antimicrobial treatment. Despite controversy stemming from nonstandardized susceptibility testing, erythromycin is the drug of choice for treating neonatal ureaplasmal infections not involving the central nervous system. The use of erythromycin is supported by its activity in vitro, limited data from clinical experience, and preliminary pharmacokinetic and safety studies.

In a total of 1,003 children (805 inpatients and 198 outpatients) with acute lower respiratory infections (ALRI), clinical, social, and environmental data were analyzed. The major clinical entities were bronchiolitis, pneumonia, bronchitis, and laryngitis. The first two of these predominated in inpatients; pneumonia and bronchitis were more common in older children, while bronchiolitis was observed in infants. Respiratory rates of > 50/min. were more common in younger children and in cases with bronchiolitis and bronchitis. Retractions showed markedly less age-dependent variations and were present in all severe cases with different clinical diagnoses. Retractions alone or associated with cyanosis were the best indicators for severity of ALRI. Among outpatients, fever and wheezing were more common; inpatients were younger, more frequently malnourished, and from a lower socioeconomic level; family history of chronic bronchitis, crowding, and parental smoking also prevailed in this group. Family asthma and exposure to domestic aerosols was more common among outpatients. Prematurity rate (17 and 15%) of all ALRI cases was twice that of the general pediatric population and a significant difference existed between in- and outpatients under 6 months of age when perinatal respiratory pathologies predominated among inpatients. It is suggested to consider the need for assessing personal, family, and environmental risk factors in addition to clinical signs and symptoms when severe cases of ALRI are evaluated.

WHO estimates 250 million new cases worldwide of sexually transmitted diseases (STDs) each year. STDs of growing concern are chlamydial infections responsible for pelvic inflammatory disease (PID) in women and pneumonia and ophthalmia in newborns, and incurable viral infections, including Herpes simplex virus, human papilloma virus (HPV), hepatitis B virus, and HIV infection. HPV types 16 and 18 are associated with cervical intraepithelial neoplasia, one of the most serious complication of STDs. PID is another serious STD complication because it tends to recur and causes chronic abdominal pain, eventually resulting in hysterectomy, infertility, ectopic pregnancy, or chronic backache. STDs adversely affect pregnancy, often leading to ectopic pregnancy, stillbirth, prematurity, congenital and perinatal infections, and puerperal maternal infections. Genital ulcer diseases, e.g., chancroid, facilitate HIV transmission. HIV infection boosts the virulence of STD pathogens, e.g., Herpes simplex virus. Many people with STDs are asymptomatic and the clinical profile of STDs is always in flux, thus resulting in less than optimal case detection. Obstacles of STD treatment include antibiotic resistance of betalactamase-producing Neisseria gonorrhoea strains and the immunocompromising effect of HIV infections. Tourists are responsible for introducing HIV infection into many countries. Some countries (e.g., Saudi Arabia) require a negative HIV test before foreigners can work in those countries. Health resources are not keeping up with the spread of STDs and HIV. Governments should embark on health education campaigns to stem the spread of HIV. They should also integrate AIDS prevention with the control of other STDs.

Low birth weight, prematurity, and intra-uterine growth retardation (IUGR) are major determinants of child survival. Therefore, it is important to assess excess mortality due to human immunodeficiency virus (HIV) infection in populations where low birth weight is common. A prospective study was conducted on a total of 1385 children born to 679 HIV-seropositive and 687 seronegative women in urban Malawi. Children were regularly examined and tested for HIV. The mortality rate of children of HIV-seropositive mothers was substantiality higher (223/1000 at 12 months, 317/1000 at 24 months, and 360/1000 at 30 months, p 0.0001) than that of children of seronegative mothers (68/1000 at 12 months, 106/1000 at 24 months, and 118/1000 at 30 months). The incidence of prematurity and IUGR was also higher in infants of HIV-seropositive mothers than in infants of seronegative mothers (12.5% versus 3.8%, p 0.001 for premature and 7.7% versus 4.4%, p = 0.02 for IUGR infants). The mother-to-infant HIV-1 transmission rate was 35.1%. The overall incidence of low birth weight was 14.1%, but the incidence was 20.1% among children of seropositive mothers and 8.3% among those of seronegative mothers (p 0.001). After 12 months of age, HIV-infected children showed the highest mortality; however, uninfected children of HIV-seropositive and children of HIV-seronegative mothers had similar mortality. The mean birth weight of HIV-infected and uninfected children was not significantly different. In HIV-infected children the most frequent causes of death were diarrhea, pneumonia, and failure to thrive. Less common risk factors for child mortality included active maternal syphilis and cervicitis/vaginitis. A possible enrolment bias could have resulted in lower mortality estimates among babies of HIV-seronegative mothers. To decrease childhood mortality, a combination of interventions such as treatment of sexually transmitted infections during pregnancy and measures to reduce mother-to-infant transmission should be adopted.

The incidence and risk factors for neonatal nosocomial infection were investigated in a cohort study of 134 hospital-born infants transferred to a neonatal unit in New Delhi, India, after birth and observed for up to 72 hours. 22 of the 134 infants developed nosocomial infections. The median age at diagnosis was 184 hours. In 16 of these infants, both sepsis screen and blood culture were positive. Septicemia was diagnosed in 21 neonates; 11 had associated pneumonia and four had soft tissue infection. Multiresistant Klebsiella species was the infectious agent in 68% of cases. The overall nosocomial infection rate was 16.8/1000 patient-days and the device-associated infection rate was 11.9/1000 device-days. Factors significantly associated with neonatal nosocomial infection in the univariate analysis were low birth weight, prematurity, vaginal delivery, hyaline membrane disease, assisted ventilation, and use of peripheral venous and umbilical vascular catheters. In the final multivariate analysis, only birth weight under 1500 g (odds ratio, 3.3) and assisted ventilation for more than 72 hours (odds ratio, 14.2) remained significant risk factors. It was observed in 122 random observations in this hospital that 15-18% of nurses and residents failed to adhere to adequate hand-washing techniques. Strict adherence to aseptic protocols in neonatal units is essential to keep infection rates under control.
