Abstract: Premature rupture of membranes (PROM) is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. With respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following PROM and the role of the duration of rupture of membranes in producing morbidities and mortalities in these neonates in our hospital. Among 2357 pregnant women, we found 163 (6.91%) cases of premature rupture of the fetal membranes in Tehran Vali-e-Asr Hospital during April 2001 to April 2002. Route of delivery was cesarean section in 65.6% of women. Urinary tract infection occured in 1.8%, maternal leukocytosis and fever in 20.2% and 5.5%, chorioamnionitis in 6.1%, fetal tachycardia in 1.2% and olygohydramnios in 4.9%. Gestational age in 138 (86%) of neonates was less than 37 completed weeks. Thirty five infants (21.47%) had respiratory distress syndrome and 33 (20.245%) had clinical sepsis. Pneumonia in 6 (3.7%) and skeletal deformity in 7 (4.294%) were seen. Rupture of membrane of more than 24 hours duration occurred in 71 (43.6%) of the patients. Comparison of morbidities between two groups of neonates and their mothers according to the duration of PROM (less and more than 24 hours ) showed significant differences in NICU admission, olygohydramnios, maternal fever, leukocytosis and chorioamnionitis rates (p24 hr of PROM with an odds ratio of 2.68 and 2.73, respectively. Positive blood and eye cultures were detected in 16 cases during 72 hours of age. Staphylococcus species, klebsiella, E.coli and streptococcus were the predominant organisms among positive blood cultures. Mortality was seen in 18 (11%) of neonates because of respiratory failure, disseminated intravascular coagulation, septic shock, and a single case of congenital toxoplasmosis. In this study, the prevalence of prematurity, sepsis and prolonged rupture of membrane were higher than previous studies.

Abstract: Despite improvement of mechanical ventilation devices for infants, lung injury still causes morbidity and mortality in many cases. To determine the effect of high frequency oscillatory ventilation (HFOV) in infants with severe respiratory failure, 10 neonates were evaluated prospectively. Mean gestational age of these patients was 35 weeks and alveolar-arterial oxygen gradient (A-aDo2) and the ratio of arterial to alveolar oxygen pressure (a/A) immediately before HFO were 610 torr and 0.072 respectively. These neonates were received inspired oxygen concentration of >95% with a mean airway pressure of 12 cm H2O by conventional mechanical ventilation. The A-aDo2 and a/A after 6 and 24 hrs on HFO was not significant in those infants with survived compared with those who died. Comparison of 3 alive neonates with 7 deaths, demonstrate that pulmonary hypoplasia, HMD accompanied with asphyxia, congestive heart failure with pneumonia are associated with poor outcome. The mean a/A ratio during 24hrs of HFO in the alived HMD group was 0.75 compared with 0.25 in those who died. It is possible that we can use this as a prognostic factor in survival. In this study, the positive effect of HFOV was demonstrated in those with no predisposing factors such as pulmonary hypoplasia, congestive heart failure, pneumonia and asphyxia.

Abstract: Pre-eclamsia is reported in 5-7% of all pregnancies. The prevalence of eclampsia is reported to be 1.2-2.2 per thousand deliveries. Fetal loss and neonatal death rate is 2-5 times more than normal, which could be partly due to the necessity of early delivery. In this study, the severity and frequency of several neonatal complications, their relationship with the severity and timing of Pre-eclampsia, and predisposing maternal factors were evaluated.

Abstract: Neonatal septic arthritis and osteomyelitis is not prevalent in first month of the life in new borne children. According to anatomic specifications of bones in this period, the manifestation of disease is different from other periods of life and the disability induced, will be serious and permanent. In this investigation, 31 infants with the diagnosis of septic arthritis and osteomyelitis were studied during 10 years. Hyperbilirubinemia (58.1 percent), emergency cesarean (25.8 percent), umbilical vessel catheterization (26.6 percent), permaturity (12.9 percent), perinatal asphyxia (9.7 percent), scalp laceration (6.5 percent), omphalitis & previous bone fracture (6.5 percent) were the most common findings among predisposing factors. Previous hospital admission was detected in 19 patients (67.3 percent) and multiple bone involvements demonstrated in 12 (38.7 percent). From those who had risk factors, 42.3 percent had multiple bone lesions. Only 5 patients (16.12 percent) had no predisposing factors. The mean age for diagnosis and seeking admission were 23 and 30 days respectively and the mean age of diagnosis at surgery was over 72 hours in 15 (48.38 percent) cases. All with delaying in requesting admission had destructive changes in their joints. Knee and hip were most involved (77.3 percent). The most common microorganisms found in this study were staphylococcus aureus and klebsiella. Of all, 47 percent were gram negative & 53 percent gram positive microorganisms. Existence of risk factors and previous hospital admission in the majority of cases accompanied by microorganisms such as methiciline resistant S.aureus and klebsiella as a causative agents who were also resistant to empirical antibiotics demonstrated the role of nosocomial infections as an important cause of infection.

Abstract: Hypothermia is one of the main causes of neonatal mortality in developing countries. The aim of this prospective study was to determine the relationship between hypothermia at birth and the risk of mortality or morbidity among neonates born in Imam Hospital in Tehran, Iran. During a one-year period, body temperature was taken from all newborns using a low-reading rectal thermometer, immediately after their admission into the Neonatal ward of the above hospital. A temperature less than 36.5 C was considered as hypothermia. A questionnaire was filled for each subject. Using logistic regression the risk of development of respiratory distress in the first six hours of birth, hypoglycemia, metabolic acidosis, hyperbilirubinemia, scleroderma, pulmonary hemorrhage, Disseminated Intravascular Coagulopathy (DIC) in the first three days of birth were assessed and compared with the hypothermic and normothermic newborn infants. Nine hundred and forty neonates were enrolled into the study. A significant relationship was found between hypothermia and respiratory distress in the first six hours of birth and death, as well as with jaundice, hypoglycemia and metabolic acidosis in the first three days of birth (P=0.0001). Logistic regression showed that, regardless of weight and gestational age, hypothermia at birth alone could increase the risk of neonatal death (OR=3.64, CI=1.85-7.18), Respiratory distress (OR=2.12, CI=1.53-2.93), metabolic acidosis (OR=2.83, CI=1.74-4.59) and jaundice (OR=2.01, CI=1.45-2.79). Neonatal hypothermia at birth increases mortality as well as significant morbidity and hospitalization period.

Abstract: Neonatal hypoglycemia is common and its prompt management is important to reduce neurological sequelae. To determine the effect of two different glucose concentrations of intravenous (IV) fluid therapy in the incidence of hypoglycemia in sick premature infants, 200 preterm infants weighing 1500-2500 g were selected and randomly assigned into two groups. Group 1 received 10% dextrose in water (DW) and for group 2 we used 12.5% DW with recommended fluid volume according to the infant’s condition. First blood glucose sample was obtained during 2-3 hours of life before starting IV therapy and the two others were measured between 4-24 hours of life after starting IV fluid therapy. Plasma glucose < 36 mg/dl during 2-3 hours of life and level below 45 mg/dl between 4-24 hours of life were considered as hypoglycemia. Birth weight, gestational age and type of diseases in two groups were matched. Although there was no difference between volume of fluid, statistical differences were found to be significant between amounts of calories (P = 0.000) and dextrose (P = 0.000) received in two groups. We detected 15 and 30 cases of hypoglycemia in group 1 and 2, respectively. After starting IV fluid therapy, the incidence of hypoglycemia decreased especially in group 2 and comparison of cases with two consecutive low plasma glucose in two groups showed significant difference (P= 0.024, relative risk= 2.67). We recommend 12.5% DW when initiation of peripheral IV therapy is indicated in sick preterm infants weighing 1500-2500 g, especially when restriction of fluid is mandated.

Abstract: Bloody nipple discharge in infancy has rarely been reported in medical literature. We report a 7 month-old female infant with a one month history of bilateral nipple discharge. Endocrinologic and hematological workups were within normal limits. Breast ultrasonography showed two non-echogenic cystic areas in each breast. The problem resolved after a period of observation. This is a benign condition and resolves spontaneously, but if persistent, should be properly investigated. Biopsy or excision is not indicated. We recommend breast ultrasonography for the follow-up of this condition.

Abstract: Among 2357 prenant women at Tehran Valiasr hospital, 99 women under 18 years with their 102 neonates were evaluated retrospectively during Aprill 1999 to April 2000. frequency of adolescent pregnancy was detected in 41.5 per 1000 live birth 7 (7.1%) of mothers had preeclampisa, 7 thyroidal diseases, 3 valvular heart diseases, 2 urinary tract infections and 20.3% of women had prolonged rupture of membrane (more than 24 hrs). the route of delivery in 21.2% of women was cesarean section. 32% of neonates were low birth weight and the gestational age in 38.2% of neonates was lower than 37 weeks. Intrauterine growth retardiation was detected in 11.8% of patients 38.2% of babies were admitted into neonatal care unit. Perinatal resuscitation and ventilator care were needed in 9.8% and 3.9% of neonates respectively. Nonatal mortality occurred in 6.9% of patients. Compared with total deliveries the frequency of variables was higher than could be expected except for cesarean section. Our adolescent pregnancy rate is lower than worldwide range but rates for prematurity and low birth weight are the same as other reports from developed and developing countries. Frequency of cesarean section was lower than expected range in this group as in developed countries.With respect to higher rates for rheumatic heart disease, premature labor, prolonged rupture o membrane and low birth weight, it seems that lower socioeconomic factors may result in these adverse outcomes.Higher neonatal ICU admissions, artificial ventilation and resuscitation in adolescent pregnancies suggest that confinement in hospitals with level III nurseries is advisable in these high risk group

Abstract: Objective: Low-level laser therapy (LLLT) has been increasingly in use over the last few decades in both medicine and dentistry. It has been suggested that LLLT may be helpful in pulpal wound healing following pulp exposure. The purpose of this study was to comparethe effectiveness of LLLT and formocresol (FC) application in healing of remaining pulp following pulp amputation in primary molars.Materials and Methods: A total of 23 contralateral pairs of teeth from 11 children aged 4 to 7 years were selected and matched using clinical and radiographic criteria. One toothfrom each pair was randomly assigned to the LLLT pulpotomy and the to FC pulpotomy group. During a 6-month follow-up period, the teeth were examined clinically and radiographically.Eight patients (four in each group) completed six-month and 6 patients (threein each group) completed one-year follow-up.Results: Clinically, no complication was observed in the teeth. However, radiographic assessment revealed signs of periradicular radiolucency in two teeth in LLLT group.Conclusion: Findings of this investigation show that LLLT can be used successfully as a complementary step to pulpotomy procedure in order to help the healing of amputated pulp. Longer follow-up periods are recommended to investigate long-term effect of LLLTpulpotomy on pulp.
