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
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
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
Background: The use of synchronized intermittent mandatory ventilation (SIMV) and pressure support ventilation (PSV) have been used for older children and adults. The purpose of this study was to compare PSV and SIMV modes in weaning from mechanical ventilation in neonate with respiratory failure.
Methods: A randomized clinical trial study carried out in NICU ward of Valiasr hospital Imam Khomeini Hospital complex, Tehran, Iran. Thirty neonates enrolled in two groups of 15. At the weaning time they randomly assigned to SIMV or PSV. They compared for tidal volume (VT), peak inspiratory pressure (PIP), incidence of pneumothorax, weaning failure and duration of weaning. For two groups to be homogeneous, maternal disease during pregnancy were also considered.
Results: In this study, VT, PIP, incidence of pneumothorax and weaning failure did not differ between groups duration of ventilation of the two methods (hours) and duration of hospitalization (days) were separately calculated. The only meaningful difference in two groups were due to weaning duration. The neonates weaned by PSV mode experienced shorter weaning time. (6.05 hours). The weaning time in SIMV mode was longer (45 hours) (P=0.006). There were no other meaningful differences between the two groups
Conclusions: According to the results of this study there were no advantage using PSV over SIMV except that the weaning time were shorter in PSV. This decrease in weaning time causes less dependence of the neonate to the ventilator and as a result secure them from complications.

Background: American pediatric Association proposes to
screen all neonates with Oto-Acoustic Emission (OAE). In developing countries, because of several limitations,
health policy makers recommend to screen only in high risk patients. This study is performed with the aim to screen
hearing loss in 950 high risk newborns hospitalized in hospitals
affiliated to Tehran University using the OAE test.
Methods: A total of 950 neonates hospitalized in the Neonatal and NICU wards of
Vali-e-Asr, Shariati, Medical Center and Bahrami Hospitals during the years 2004-2006 who
showed at least one risk factor using TEOAE hearing test were enrolled into this cross-sectional
descriptive analytical study and were diagnosed with mild deafness and total
deafness. Blood exchange due to hyperbillirubinemia, septicemia, congenital
heart disease, the fifth minute apgar scores below six, PROM more than six hours, epilepsia, need to NICU more than five hours, pneumonia and Oto-Toxic drugs
were considered as risk factors. Data was past medical history, current
disease, admission cause, sign & symptoms and complications of disease.
Results: Multivariate logistic regression and paired t-test
showed that blood exchange, low birth weight and low first minute Apgar scores
had the highest independent risk for hearing loss among newborn.
Conclusion: Despite of the low prevalence of neonatal hearing loss,
screening of hearing loss at early stages is important.

Abstract
Background: Soft tissue chondroma is a rare slow-growing benign cartilage forming
tumor. Tumors of this kind arise from the relative mesenchymal tissue and have tendency to occur in the fingers and toes. Due to its rarity, this tumor is likely to go undiagnosed. Histopathological examination usually reveals the correct diagnosis.
Case presentation: Hereby, we report a case of soft tissue chondroma in a 27 year-old woman presented with a slow-growing mass in the volar aspect of her right hand. The tumor had developed over a 7-month period. The skeletal system was unremarkable on X-ray evaluation. The lesion was excised and the histopathological findings revealed a well-delineated cartilaginous neoplasm with lobular pattern. The tumor was composed of mature chondrocytes without atypia and the findings were compatible with chondroma.
Conclusion: There are various hypotheses about the etiology of soft tissue chondromas and their microscopic findings are variable. They have a good prognosis. Recurrence is rare and malignant transformation has not been reported yet.

Abstract
Background: Ventilator Associated Pneumonia (VAP), developing in mechanically ventilated patients after 48 hours of mechanical ventilation, is the second most common nosocomial infection. Therefore, there is a vital need to study the etiology and risk factors associated with VAP in neonates.
Methods: Neonates admitted to neonatal intensive care unit (NICU), over a period of one year and who required mechanical ventilation for more than 48 hours were enrolled consecutively into the study. Semi-quantitative assay of endotracheal aspirate was used for microbiological diagnoses of VAP. 105CFU/ml was taken as the cut off between evidence of pathological infection and colonization. The primary outcome measure was the development of VAP. Secondary outcome measures were length of mechanical ventilation, NICU length of stay, hospital cost, and death.
Results: Thirty eight patients were enrolled (58% were boys and 42% were girls). 42% of neonates developed VAP. The most common VAP organisms identified were Acinetobacter baumanni (43%). On multiple regression analysis, duration of mechanical ventilation was associated with VAP (P=0.00). Patients with VAP had greater need for mechanical ventilation (18.7 vs 6 median days), longer NICU length of stay (39 vs 21.5 median days) and higher total median hospital costs (79.5 vs 52 million rials) than those without VAP. The mortality rate was not different between two groups.
Conclusion: In mechanically ventilated neonates, those with VAP had a prolonged need for mechanical ventilation, a longer NICU stay, and a higher hospital costs. Longer mechanical ventilation was associated with an increased risk of developing VAP in these patients. Developing of VAP didn’t increase mortality in patients.

Abstract
Background: The aim of this study was to assess the role of consolidative intraperito-neal chemotherapy with carboplatin in decreasing relapse and increasing survival in advanced epithelial ovarian cancers, as well as evaluation of its toxicity.
Methods: In this clinical trial 30 patients with epithelial ovarian cancer in stages II-IV who had complete surgery (optimal debulking surgery) received six standard cycles of intravenous carboplatin and paclitaxel. They were enrolled through non-random se-quential selection. The control patients were similar to case group in stage (II-IV) and pathology (epithelial ovarian cancer). The control group was evaluated retrospectively through hospital files. This clinical trial performed in Gynecology Oncology department in Tehran Valiasr University Hospital, during 2005-2010. They including 18 cases as the intervention group receiving intraperitoneal chemotherapy and 12 patients as the control group with only retrospective follow-up. The cases received 3 cycles of 400 mg/m2 intraperitoneal carboplatin every 21 days following intravenous chemotherapy. Relapse of disease was diagnosed as increasing or even doubling CA125 serum titer during one month, or any CA125 above 100 IU, or an abdominal or pelvic mass in ul-trasound or physical exam. Mean survival of two and five years, progression-free inter-val (PFI), overall survival (OS), relapse, demographic parameters, drug toxicities, path-ologic types of cancers in two groups were coded and compared using SPSS 14. Any P<0.05 was considered as a significant difference.
Results: The mean ages of cases and controls were 52.4±8.6 and 55.1±11.5 years. The mean duration of relapse-free survival was 13±8.6 months for the cases and 9.5±4.3 months for the control patients (not statistically different, P>0.05). The mean overall survival for cases and controls were 39±16.5 and 30.8±16.2 months, respectively (no significant difference, P>0.05). The frequency of drug toxicities in the cases was 5.6%, and consisted of mild-to-moderate abdominal pain, nausea and vomiting.
Conclusion: It seems that consolidation therapy with intraperitoneal carboplatin may not increase overall survival, reduce relapse rate or decrease mortality, though it does not induce considerable side effects. Since the mean survival in the intervention group was nine months more than controls, this difference may be clinically significant.

Abstract
Background: The occlusion of the artery and vein grafts are currently a major problem in coronary bypass surgery. Degradation of collagen and elastin, the most abundant extracellular matrix proteins in the vessel wall by matrix metalloproteinase (MMPs), leads to a rearrangement of the extracellular matrix and vascular wall structure. The present study aimed to compare the histological and biochemical characteristics of arteries and veins which could have a role in the failure of the graft.
Methods: This study was a cross-sectional study of 80 patients conducted at Heart Hospitals in Isfahan, Iran, between July 2012 and November 2013. Samples were collected from the remains of vessels used in bypass surgery of 11 male nondiabetic patients. The histologic, collagen elastin ratio and MMPs levels of the vessels were investigated. MMPs were determined using the Gelatin Zymography method. For elastin and collagen content measurement, the sample was digested by cyanogen bromide and hydrochloric acid and then hydroxyproline was measured with a spectrophotometer.
Results: The amount of active and inactive MMP-2 and MMP-9 of the left internal mammary artery (Lima) was similar to aorta, but the amount of MMP-2 and MMP-9 in the radial artery and saphenous vein were significantly higher than aorta. Elastin to collagen ratio in Lima (1.92±1.15) was similar to the aorta (3.4±1.66), but this proportion in saphenous vein (1.07±0.47) and radial artery (1.14±0.39) was significantly lower in the aorta (P≤0.05). Most patients had atherosclerotic plaque in radial while there was atherosclerotic plaque in Lima of only one case.
Conclusion: The presence of atherosclerotic plaques in radial and thickening of the intimal layer of the saphenous vein in the majority of patients and decrease of collagen to elastin ratio and the high level of matrix metalloproteinase enzymes in the radial and saphenous vein can induce early pathological conditions, and remodeling of the vessels involved. So the results of this study confirm that Left Internal Mammary Artery (LIMA) is the most suitable candidate for bypass surgery.

Abstract
Background: Respecting gestational age and medical intervention at birth, Combined Apgar score, a new method proposed by American Academy of Pediatrics (AAP) may better evaluate neonatal condition at birth compared with conventional Apgar score. The combined Apgar consists of the Specified and the Expanded Apgar describe a more detailed condition at birth. In Expanded Apgar, administered intervention and in Specified Apgar, infant`s condition regardelless of gestational age and intervention are emphesised. To evaluate combined Apgar score in perinatal asphyxia, we compared conventional versus Combined Apgar scores to anticipated neonatal asphyxial complications.
Methods: In a prospective cohort study, we assessed 464 neonates admitted in, Vali-e-Asr University Hospital, during one year from September 2012 to September 2013. We assessed neonates by Conventional and Combined Apgar scoring at 1, 5 and 10 minutes after birth. Asphyxia was recognized based on newborn`s records. Diagnostic criteria for asphyxia include, occurrence of metabolic or mixed acidosis, apgar score less than three in 5th minute, occurrence of neurological complications like seizure, hypotonia, coma and multiple organ failure. Then we used SPSS V16 for data analysis and compare sensitivity between two methods of Apgar scoring.
Results: From 2200 delivered neonates, we assessed 464 neonates. 9.3% of studied neonates had Asphyxia, which equals 2% of live births. The Apgar score was lower in asphyxiated neonates by both methods (6±1 vs. 9±1 according to conventional method and 9±1 vs. 16±1 scored in combined method). Combined method was more sensitive than the Conventional Apgar scoring (99% vs. 88%).
Conclusion: In asphyxiated neonates sensitivity and specificity of combined apgar were more than conventional apgar. With respect to this study, better assessment could be achieved by combined apgar score method instead of conventional Apgar.

Abstract
Background: The incidence of Patent Ductus Arteriosus (PDA) in premature infants whose birth weight is less than 1500 grams is approximately 30-60%, most of them need medical or surgical interventions. The purpose of this study is to determine the efficacy of prophylactic treatment with oral paracetamol (Acetaminophen- Hakim® Oral Drops 100 mg/ml, Hakim Pharmaceutical Co., Tehran, Iran) for PDA in preterm infants.
Methods: A randomized clinical trial conducted from March 2012 to March 2013. Thirty-two preterm newborns whose gestational age was under 32 weeks and birth weight was 1500 grams or less, admitted in neonatal intensive care unit (NICU) of Vali-Asr Hospital, Tehran were studied prospectively. They were randomly assigned in two groups. The prophylaxis group received oral paracetamol for a period of two days starting during first 24 hours of life. No placebo was given to the control group. Echocardiography was performed 24-36 hours after the last given dose in prophylaxis group and on the 4th and 5th day in control group. A p-value less than 0.05 are considered significant.
Results: There were 16 newborns in each group (20 boys and 12 girls). In 12 newborns of prophylaxis group the ductus arteriosus was closed although in control group in 8 newborns the duct was closed. No significant difference was observed in sex, gestational age, birth weight, mode of delivery, multifetal gestation and birth order between two groups. The rate of ductal closure was 75% and 50% in prophylaxis group and control group respectively (P=0.27).
Conclusion: Our study demonstrated that prophylactic paracetamol is ineffective in PDA closure, although the rate of ductal closure between two groups seems remarkable. Paracetamol as a new strategy for PDA closure because of cost effectiveness and harmlessness may be used in future. However, we presume larger sample size studies are needed to show the efficacy of paracetamol, side effects, and complications in PDA prophylaxis treatment.
