RESUMEN

PURPOSE: Intraabdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are associated with high mortality rates in children (40-60%). However, literature lacks comprehensive series in childhood. In this study, we aimed to determine the incidences of IAH and ACS, to identify high risk disorders for the development of IAH/ACS and to decrease ACS-associated mortality by early diagnosis and timely intervention. METHODS: A prospective study was performed between December 2009 and October 2010 in our institution. IAH was defined by a sustained or repeated pathological elevation in IAP≥12mmHg without a new organ failure. ACS was identified as a sustained IAP>15mmHg with a new organ dysfunction/failure. After recognition of IAH or ACS, patients underwent prompt decompressive interventions as medical or surgical procedures. RESULTS: 150 patients were enrolled to the study (86 M, 64 F). The incidences of IAH and ACS were 9% and 4%, respectively. High risk disorders were trauma, ileus, necrotizing enterocolitis, abdominal wall defects, diaphragmatic hernia and septic shock with massive fluid resuscitation. 14 patients with IAH were treated and mean IAP was decreased from 13.9±1.9mmHg to 9.2±2.1mmHg (p<0.001). None of them progressed to ACS. Six patients with ACS underwent decompressive laparotomy. Mean IAP decreased significantly from 20±3mmHg to 9±1.4mmHg (p=0.001). Vital signs like mean urine output, abdominal perfusion pressure (APP) and respiratory rate were significantly improved after surgery (p<0.05). ACS-associated mortality rate was determined as 16%. CONCLUSIONS: IAH or ACS was occurred in nearly one tenth of patients admitted to neonatal and pediatric intensive care units. High clinical suspect must be drawn on to recognize and treat these clinical complications more efficiently. Regular and frequent IAP measurement in high risk disorders is essential for early diagnosis. Lower mortality rates can be achieved by early recognition and timely intervention in children.

RESUMEN

PURPOSE: To evaluate the impact of new legislation for assisted reproductive technology (ART) restricting the number of transferred embryos on neonatal prognosis of infants born after infertility treatments. MATERIALS AND METHODS: Neonatal records of all live born infants in Ege University Maternity Ward were reviewed for 2006 and 2012. Neonatal outcome measures such as birth weight (BW), gestational age (GA), preterm birth (PTB), very low birth weight (VLBW), and neonatal intensive care unit (NICU) admission were evaluated. RESULTS: Compared to 2006 percentage of newborns conceived by medically assisted reproduction (MAR) decreased from 14.6% to 5% in all live births, from 23.8% to 8.2% in NICU patients in 2012. The number of fetuses in the last pregnancy, frequency of intrauterine reductions, spontaneous pregnancy losses, antenatal bleeding, and premature delivery decreased. Percentage of multiples among MAR newborns (31.7% vs. 55.7%), twins from 51.4% to 30.9%, triplets from 4.3% to 0.8% all decreased significantly. Mean BW and gestational age increased resulting in decreased frequency of PTB and VLBW. Consequently Level 3 NICU admission rate significantly decreased from 44.3% to 22%. CONCLUSION: The new ART legislation in Turkey resulted in decreased rate of multiple births, prematurity and related complications, and NICU admissions in MAR newborns. However the twin rates are still high. Since uncontrolled ovulation stimulation and intrauterine insemination techniques are also associated with multiple births and unfavorable neonatal outcomes, these procedures deserve close monitorization.

RESUMEN

It is difficult to predict outcome in neonates that experience perinatal hypoxic ischaemia. Morbidity and mortality may be affected by genetic factors that augment inflammatory and coagulative responses. This prospective study analysed the effects of proinflammatory cytokine gene polymorphisms (tumour necrosis factor-α [TNFA] 308G>A and interleukin-6 [IL6] 174G>C) and prothrombotic factor gene mutations (prothrombin G20210A, factor V Leiden G1691A and methylenetetra hydrofolate reductase [MTHFR] C677T) on the early neurological prognosis in 40 term hypoxic ischaemic encephalopathic neonates. There were significant relationships for Sarnat and Sarnat staging with electroencephalographic findings, transfontanelle ultrasound (US) results, early neonatal outcome and neurological morbidity. Genetic mutations in the prothrombotic proteins, the TNFA 308G>A polymorphism and the cerebrospinal fluid levels of TNF-α protein were not related to clinical stage, electroencephalography, transfontanelle US or neurological status at discharge or at postnatal months 6 and 12. The IL6 174GC genotype demonstrated a protective role, being significantly correlated with normal electroencephalography, transfontanelle US and normal neurological findings at discharge. In conclusion, the IL6 174GC gene polymorphism seems to play a role in determining the risk and/or severity of perinatal cerebral injury.

RESUMEN

This study tested whether elevated maternal ß-hydroxybutyrate (ß-OHB) levels contribute to polycythaemia in infants of diabetic mothers. Pregnant diabetic women (n = 27) and non-diabetic controls (n = 20) and their singleton infants were included. Maternal glycosylated haemoglobin and ß-OHB levels were studied at 34-36 weeks' gestation; levels were significantly higher in mothers with diabetes than in controls. Birth weights and cord blood levels of insulin and fetal haemoglobin were significantly higher in infants from diabetic mothers compared with control infants, as were haematocrit levels in venous blood samples taken from each infant at 4 h following delivery. Cord blood erythropoietin levels were similar in both groups. There was a positive strong correlation between maternal ß-OHB levels and polycythaemia in newborn infants, indicating that ß-OHB could activate erythropoiesis independently from intrauterine hyperinsulinaemia and/or erythropoietin levels, and may be important in the pathogenesis of polycythaemia in infants born to diabetic mothers.

RESUMEN

PURPOSE: To evaluate dynamic and static properties of lateral canthal tendon and involutional periorbital anthropometric and lateral canthal changes with any possible effect of sleep reference side on these changes. METHODS: Ninety-two healthy adult subjects with a mean age of 43.5 years were enrolled in the study. Lateral canthal tendon lengths (LCT), canthal movement amplitudes, and other periorbital anthropometric parameters were measured. Any effects of age and sleep preference side on anthropometric and particularly lateral canthal tendon measurements were evaluated. Pearson correlation analysis, one-way analysis of variance, and t-test for paired samples were used for statistical evaluation. RESULTS: LCT length was weakly correlated with age, lower lid tractability, horizontal palpebral fissure length, and interpupillary distance and also inversely correlated with margin reflex distance, but not with other measurements. Age was also correlated with lower lid tractability, and with the ratio of LCT to the horizontal palpebral fissure length (LCT-HPFL). No correlation between age and horizontal palpebral fissure length was detected. Age was weakly and inversely correlated with canthal height but not with canthal movement amplitudes. No effect of sleep preference side on LCT length, canthal height, or lower lid tractability was detected. CONCLUSIONS: Lateral canthus has a dynamic structure that is not correlated with any other periorbital anthropometric measurements. LCT length is correlated with lower lid tractability, and increases with age, unlike horizontal palpebral fissure that stays constant with increasing LCT-HPFL ratio. Sleep preference side has no effect on the eyelid metrics and LCT.

RESUMEN

OBJECTIVE: Although cutaneous leishmaniasis (CL) occurs mostly in the facial area, periocular involvement accounts for 2-5% of the facial lesions. CL lesions localized in the periocular region can easily be confused with various other diseases. The aim of this study was to examine the frequency of periocular involvement in CL in the Cukurova region of Turkey, as well as the clinical characteristics, diagnosis and methods of treatment of this disease. METHODS: Between December 1998 and December 2004, patients who were diagnosed with CL were evaluated prospectively with respect to periocular involvement. RESULTS: From the 2066 patients evaluated with CL, 2622 lesions were identified. In 59 (2.9%) of these patients, a total of 66 (2.5%) lesions were located in the periocular area. Thirty-two (48.5%) of these lesions were of the papular type, 15 (22.7%) the nodulo-ulcerative type, 10 (15.2%) the plaque type, and nine (13.6%) the nodular type. Dacryocystitis was identified in four patients with periocular involvement. Over the follow-up period, no ocular or periocular deformities or complications developed in these patients. CONCLUSION: Patients suspected of CL should be evaluated and treated early in the course of their disease to prevent any permanent ocular or periocular deformities.

RESUMEN

This study compared maternal and neonatal outcomes in women undergoing elective caesarean section under general anaesthesia with desflurane or sevoflurane; the neonatal effects were also compared with those in women undergoing epidural anaesthesia. Fifty women requesting general anaesthesia were randomly assigned to receive either 3% desflurane or 1% sevoflurane. Twenty-five women requesting regional anaesthesia received epidural anaesthesia with ropivacaine. Comparing desflurane sevoflurane with respect to their maternal haemodynamic effects, maternal blood pressure levels were higher and tachycardia was more frequent in the desflurane group. Comparing general and epidural anaesthesia, no significant differences were detected in terms of neonatal Apgar scores or neurological adaptive capacity scores. In conclusion, 3% desflurane or 1% sevoflurane for general anaesthesia and ropivacaine for epidural anaesthesia for elective caesarean section had similar effects on neonatal outcomes. In women who received desflurane, blood pressure and heart rate elevation were significantly higher than in the sevoflurane group, though this difference did not have any clinical importance.

RESUMEN

We aimed to evaluate retrospectively the clinical and bacteriological efficacy and potential side-effects of teicoplanin treatment in neonates with proven staphylococcal infection. There were 37 episodes of staphylococcal septicaemia in neonates with a mean gestational age of 34.2 +/- 2.3 weeks; 26 were caused by coagulase-negative staphylococcal (CoNS) sepsis and 11 by Staphylococcus aureus sepsis. All episodes were treated with teicoplanin (intravenous loading dose 16 mg/kg followed by a maintenance dose of 8 mg/kg daily). The methicillin resistance and antibiotic susceptibilities of both micro-organisms were evaluated. Bacterial eradication was achieved in 89.1% of cases and mortality was 16.2%. The mean duration of treatment of the survivors was 11.6 +/- 2.3 days. There were no drug-related adverse events and the biochemical and haematological tests showed no clinically significant changes in relation to teicoplanin therapy. Our results suggest that teicoplanin is highly effective in neonatal staphylococcal sepsis.

RESUMEN

The mortality and various morbidity rates have been substantially reduced by means of exogenous surfactant replacement, the cornerstone in the treatment of respiratory distress syndrome (RDS) in premature infants. The objective of this study is to compare two natural surfactant preparations (Alveofact(R), Survanta(R)) in terms of effectiveness and side-effects. A total of 50 infants with RDS were given surfactant due to RDS were taken into the scope of this study. Survanta(R) and Alveofact(R) were administered to randomized infants with RDS and the results obtained during clinical observations were compared. Second hour mean FiO (2), MAP and a/APO (2) values showed changes in favour of Alveofact(R) (n = 25) group compared to the Survanta(R) (n = 25) group (p < 0.05 for each parameter). However, this difference disappeared in the 6 (th) hour. No statistical difference was established between the two groups with regard to sideeffects (pneumothorax, sepsis, intraventricular hemorrhage, bronchopulmonary dysplasia), duration of mechanical ventilation in survivors, duration of hospitalization in survivors and mortality before the 28 (th) day. It was concluded that results obtained with different surfactant preparations having dissimilar compositions were not different in terms of final impacts and side-effects.

RESUMEN

Normal fertility is sustained by progress in the medical therapy of Wilson's disease; however, pregnancy complications are encountered more frequently. The mother we present is a Wilson's disease patient who had been compliant with D-penicillamine for the preceding 13 years. She was admitted with unplanned pregnancy at the 16th gestational week. The dose of D-penicillamine could be reduced to 600 mg/d related to the underlying disease. Pregnancy ended with premature labor and delivery at the 29-30th weeks. The baby experienced type I respiratory distress and was treated by surfactant and mechanical ventilation. Neutropenia and leucopenia were documented at 6th postnatal hours. The baby showed neutropenia and leucopenia for 5 days and resolving without any further therapy. Intrauterine D-penicillamine was suspected to cause transient neonatal myelosuppression.

RESUMEN

Intestinal bacterial proliferation is an important aspect of gastrointestinal injury in neonatal necrotizing enterocolitis (NEC). In the present investigation, we examined the protective action of oral supplementation with Saccharomyces boulardii (S. boulardii), non-pathogen probiotic yeast, against hypoxia-reoxygenation (H/R)-induced NEC in young mice. Young mice were divided into three groups; Group 1 mice (untreated) were subjected only to hypoxia-reoxygenation; Group 2 mice were subjected to hypoxia-reoxygenation and were then given lyophilized S. boulardii (10 mg suspended in 0.5 ml saline) twice a day by orogastric intubation for 10 days. Group 3 mice served as controls. Hypoxia was induced by placing young mice in a 100 % CO (2) chamber for 5 min. After hypoxia, the young mice were reoxygenated for 10 min with 100 % oxygen. We examined the intestinal lesions by light microscopy and measured intestinal generation of PAF and TNF-alpha in the H/R-induced model of NEC. In the probiotic group, NEC-induced intestinal tissue damage was greatly attenuated, with necrosis partially limited to the mucosa. Both intestinal tissue PAF and TNF-alpha concentrations were significantly higher in the untreated group than in controls (p < 0.001). S. boulardii-supplemented young mice showed a significant decrease in intestinal generation of PAF compared with untreated young mice (p < 0.05). On the other hand, no significant difference was observed in the intestinal concentration of TNF-alpha between untreated and probiotic groups ( p > 0.05). The present study suggests that hypoxia/reoxygenation plays an important role in the pathogenesis of NEC and supports hypothesis that especially PAF and TNF-alpha are involved in the pathophysiological mechanism of H/R-induced NEC. This study also demonstrates that dietary supplementation with S. boulardii ameliorates the histologic evidence of H/R-induced intestinal injury. Based on these findings, the beneficial effects of probiotic S. boulardii in this model of NEC are mediated via mechanisms inhibiting intestinal proinflammatory mediator release.

RESUMEN

Platelet-activating factor (PAF), leukotriene B(4) (LTB(4)) and other cytokines have been indicated to be responsible for the neuronal damage in hypoxic-ischemic brain. Diets in omega-3 (n-3) fatty acids appear to have an antiinflammatory effect, which is thought to be due to decrease in active prostaglandins and leukotrienes production after incorporation of these fatty acids into cell membrane phospholipids. We investigated the effect of dietary supplementation with n-3 fatty acids on endogenous PAF and LTB(4) biosynthesis in hypoxic-ischemic brain of young mice. Young mice were randomly divided into four groups: Group 1 mice were fed standard chow (n-3 polyunsaturated fatty acids free); Group 2 and Group 3 mice were given standard diet supplemented with 10% by weight of fish oil, as source of n-3 polyunsaturated fatty acids, for 3 and 6 weeks, respectively. Group 4 mice served as control. We injured the right cerebral hemisphere of young mice by ligating the right common carotid artery and exposing the mice to 8% oxygen for 60 min. Approximately 10-fold increase in PAF concentration was determined in hypoxic-ischemic brain tissue of Group 1 mice. Tissue concentration of PAF showed a profound decline in Group 3 mice compared to Groups 1 and 2 (P<0.01, P<0.05, respectively). LTB(4) was also significantly elevated in the brain of Group 1 mice when compared to the brain of control mice (P<0.001). A striking decline was observed in the concentration of LTB(4) in both Group 2 and Group 3 mice compared to Group 1 mice (P<0.05, P<0.01, respectively). The present study shows that n-3 fatty-acid-enriched diet inhibits endogenous PAF and LTB(4) generation in hypoxic-ischemic brain tissue; however it demonstrates that 6 weeks of dietary supplementation with n-3 fatty acids results in a significant decrease in tissue level of PAF in the brain.

RESUMEN

Molybdenum cofactor deficiency is a rare and devastating disease leading to intractable seizures in the neonatal period. Severe loss of neocortical neurons, gliosis, and cystic necrosis of cerebral white matter resulting in significant cerebral volume loss are the neuropathological findings. The mechanism of cerebral injury is unknown, but sulphite excess, and sulphate or uric acid deficiencies are possible factors. We present here a new case of Molybdenum cofactor deficiency associated with Dandy-Walker complex with a history of three dead siblings, the latter also having Dandy-Walker malformation. We speculate that severe cerebral volume loss due to the above mentioned mechanisms may lead to an appearance resembling Dandy-Walker malformation.

RESUMEN

In the present investigation, we studied the effect of recombinant human erythropoietin (r-HuEPO) on serum malondialdehyde (MDA) as an index of lipid peroxidation, related to iron-catalyzed free radical reaction and erythrocyte superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) activities in very-low-birth weight (VLBW) infants. Forty premature infants, at gestational ages were less than 33 weeks and birthweights were less than 1,500 g, were enrolled in the study. The study population was randomly divided into 2 groups. Twenty infants in Group 1 (treatment group) were given r-HuEPO, and 20 infants in Group 2 served as the control. r-HuEPO treatment (750 U/kg a week) was initiated on the 10th day of life and continued for 6 weeks. Preterm infants given erythrocyte transfusions during the study were excluded from the results. Serum ferritin and MDA levels, and erythrocyte superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) activities were analyzed at the end of the first week of life (at the beginning of the study). Subsequently, serum ferritin, and MDA levels were measured at the end of the 3rd and the 6th week. SOD, CAT, and GPX activities in the hemolysate were analyzed at the end of the 4th week. Six infants in the control group and 1 infant in the r-HuEPO group received transfusions through the end of the study, and these infants were excluded from the results. Significantly decreased serum ferritin concentrations were found in the r-HuEPO group compared to those in the control group both at the end of the 3rd and the 6th week (P < 0.05, and P < 0.01, respectively). In addition, serum MDA levels were also significantly reduced in Group 1 compared to control both at the end of the 3rd and the 6th week (P < 0.01 and P < 0.05, respectively). A good correlation was found between serum MDA and ferritin levels in Group 1. When the 2 groups were compared with respect to activities of SOD, CAT, and GPX at the end of the 4th week, no differences were observed. Our findings in this study show that administration of r-HuEPO significantly decreases lipid peroxidation, but does not affect erythrocyte antioxidant enzyme(s) activities in preterm infants. The mechanism responsible for the r-HuEPO-induced decrease in lipid peroxidation may concern inhibition to iron-catalyzed free radical reactions.

RESUMEN

In the present study, the records of 242 children, aged 1-14 years, admitted with perforating ocular injury were reviewed retrospectively over a 5-year period. There were 175 boys and 67 girls in the study group. The patients were divided into 3 groups according to their ages. Perforating injuries occurred most frequently in the street in all groups. The second most common place of the injury was at home in the 1-9 year-olds and in the fields in the 10-14 year-olds. The cause of the perforation was a metallic substance in 32.6%, wood in 15.3%, stone in 12.0%, glass in 12.3%, pellets in 12%, and injection needles in 8.3%. Most of the perforations occurred during unsupervised play, while all perforations with glass occurred during traffic accidents. Surgery was performed in 234 patients, while 8 patients in whom spontaneous closure had already occurred during admission received only medical treatment. In 28.9% the visual acuity was undetermined, in 25.7% the visual acuity was 0.1 or more, in 22.7% the visual acuity was between 0.06 and light perception, and in 22.7% there was no light perception on final evaluation. It is emphasized that educative and legislative measures such as informing the parents, teachers and children about the causative factors and potential hazards of perforating ocular injuries and restricting the availability of dangerous items to children, should be taken into consideration in order to prevent perforating ocular injuries in children.
