    We present a case of bilateral severe retinal edema with subretinal fluid in an infant diagnosed with neonatal hemochromatosis and liver failure. A macular cherry-red spot in each eye mimicked the clinical appearance of many metabolic storage diseases. Both the clinical retinal appearance and the anatomic abnormalities observed on spectral domain optical coherence tomography resolved after successful liver transplant.

    Neonatal lupus is a rare and acquired autoimmune disease. Central nervous system abnormalities are potential manifestations in neonatal lupus. Through a systematic literature review, we analyzed the clinical features of previously reported neonatal lupus cases where central nervous system abnormalities had been identified. Most reported neonatal lupus patients with central nervous system involvement were neuroimaging-determined and asymptomatic. Only seven neonatal lupus cases were identified as having a symptomatic central nervous system abnormality which caused physical disability or required neurosurgery. A high percentage of these neurosymptomatic neonatal lupus patients had experienced a transient cutaneous skin rash and had no maternal history of autoimmune disease before pregnancy.

    D-myo-inositol-1,2,6-trisphosphate (IP3) is an isomer of the naturally occurring second messenger D-myo-inositol-1,4,5-trisphosphate, and exerts anti-inflammatory and antiedematous effects in the lung. Myo-inositol (Inos) is a component of IP3, and is thought to play an important role in the prevention of neonatal pulmonary diseases such as bronchopulmonary dysplasia and neonatal acute lung injury (nALI). Inflammatory lung diseases are characterized by augmented acid sphingomyelinase (aSMase) activity leading to ceramide production, a pathway that promotes increased vascular permeability, apoptosis, and surfactant alterations. A novel, clinically relevant triple-hit model of nALI was developed, consisting of repeated airway lavage, injurious ventilation, and lipopolysaccharide instillation into the airways, every 24 hours. Thirty-five piglets were randomized to one of four treatment protocols: control (no intervention), surfactant alone, surfactant + Inos, and surfactant + IP3. After 72 hours of mechanical ventilation, lungs were excised from the thorax for subsequent analyses. Clinically, oxygenation and ventilation improved, and extravascular lung water decreased significantly with the S + IP3 intervention. In pulmonary tissue, we observed decreased aSMase activity and ceramide concentrations, decreased caspase-8 concentrations, reduced alveolar epithelial apoptosis, the reduced expression of interleukin-6, transforming growth factor-β1, and amphiregulin (an epithelial growth factor), reduced migration of blood-borne cells and particularly of CD14(+)/18(+) cells (macrophages) into the airspaces, and lower surfactant surface tensions in S + IP3-treated but not in S + Inos-treated piglets. We conclude that the admixture of IP3 to surfactant, but not of Inos, improves gas exchange and edema in our nALI model by the suppression of the governing enzyme aSMase, and that this treatment deserves clinical evaluation.

    Full Text Available Since arthritis induced by Mycobacterium products (adjuvant in rats is considered to be immunologically driven, the objective of the present study was to determine if the immunosuppressor drug cyclosporin could affect hindpaw edema and joint hyperalgesia simultaneously. Female Holtzman rats (140-170 g presented hyperalgesia and edema on the 8th and 12th day following adjuvant injection. Daily systemic (oral or intramuscular administration of cyclosporin (0.5-5.0 mg kg-1 day-1 or dexamethasone (0.01-0.1 mg kg-1 day-1 for 15 days starting on day zero dose-dependently inhibited the hindpaw edema and hyperalgesia in arthritic rats. However, hyperalgesia but not edema could be detected two days after cyclosporin withdrawal. We concluded that a the continuous presence of cyclosporin is essential to reduce the development of joint hyperalgesia and that b different mechanisms underlie the appearance of hyperalgesia and edema in this model. The intracerebroventricular (icv administration of 5-50-fold smaller doses of cyclosporin (1.5-150 µg/day or dexamethasone (15 µg/day also reduced the arthritic hindpaw edema and hyperalgesia. Peripheral blood from animals injected with effective systemic cyclosporin doses showed detectable levels of the drug, whereas peripheral blood from those injected with icv cyclosporin did not, as measured by specific RIA. Our results indicate that cyclosporin administered by the central route is as effective as by the systemic route to reduce joint hyperalgesia and hindpaw edema in arthritic rats. The antiarthritic effect induced by low doses of cyclosporin in the central nervous system (CNS could be explored to avoid its often associated systemic side effects during chronic therapy. However, the mechanism(s involved in the antiarthritic response to cyclosporin in the CNS remain to be elucidated

    We have reported that facilitation of central histaminergic activity prevents the development of ischemia-induced brain injury. Since cerebral edema is a major cause of brain damage, we studied effects on brain edema of postischemic administration of L-histidine, a precursor of histamine, and thioperamide, a histamine H(3)-receptor antagonist, both of which enhance central histaminergic activity. Focal cerebral ischemia for 2 h was provoked by transient occlusion of the right middle cerebral artery in rats, and the water content and infarct size were determined 24 h after reperfusion. Changes in the extracellular concentration of histamine were examined in the striatum by a microdialysis procedure, and effects of these compounds were evaluated. Repeated administration of L-histidine (1000 mg/kg x 2, i.p.), immediately and 6 h after reperfusion, reduced the increase in the water contents in ischemic regions. Simultaneous administration of thioperamide (5 mg/kg, s.c.) with L-histidine (1000 mg/kg, i.p.) completely prevented edema formation and alleviated brain infarction, although a single dose of L-histidine, immediately after reperfusion, showed no benefits. The striatal histamine level was gradually increased after reperfusion as well as during ischemia. Simultaneous administration of thioperamide with L-histidine markedly increased the brain histamine concentration, and the value increased up to 230% of that in the saline group 5 - 6 h after reperfusion. L-Histidine alone did not affect the increase in the histamine output after ischemia. These findings suggest that further activation of the central histaminergic system after initiation of cerebral ischemia prevents development of ischemia-induced brain edema.

  8. Central role of maladapted astrocytic plasticity in ischemic brain edema formation

    Full Text Available Brain edema formation and the ensuing brain damages are the major cause of high mortality and long term disability following the occurrence of ischemic stroke. In this process, oxygen and glucose deprivation and the ensuing reperfusion injury play primary roles. In response to the ischemic insult, the neurovascular unit experiences both intracellular and extracellular edemas; the two processes are interactive closely under the driving of maladapted astrocytic plasticity. The astrocytic plasticity includes both morphologic and functional plasticity. The former involves a reactive gliosis and the ensuing glial retraction. It relates to the capacity of astrocytes to buffer changes in extracellular chemical levels, particularly K+ and glutamate, as well as the integrity of the blood-brain barrier. The latter involves the expression and activity of a series of ion and water transport proteins. These molecules are grouped together around glial fibrillary acidic protein and water channel protein aquaporin 4 to form functional networks, regulate hydromineral balance across cell membranes and maintain the integrity of the blood-brain barrier. Intense ischemic challenges can disrupt these capacities of astrocytes and result in their maladaptation. The maladapted astrocytic plasticity in ischemic stroke cannot only disrupt the hydromineral homeostasis across astrocyte membrane and the blood-brain barrier, but also lead to disorders of the whole neurovascular unit. This review focuses on how the maladapted astrocytic plasticity in ischemic stroke plays the central role in the brain edema formation.

    Brain edema formation and the ensuing brain damages are the major cause of high mortality and long term disability following the occurrence of ischemic stroke. In this process, oxygen and glucose deprivation and the resulting reperfusion injury play primary roles. In response to the ischemic insult, the neurovascular unit experiences both intracellular and extracellular edemas, associated with maladapted astrocytic plasticity. The astrocytic plasticity includes both morphological and functional plasticity. The former involves a reactive gliosis and the subsequent glial retraction. It relates to the capacity of astrocytes to buffer changes in extracellular chemical levels, particularly K(+) and glutamate, as well as the integrity of the blood-brain barrier (BBB). The latter involves the expression and activity of a series of ion and water transport proteins. These molecules are grouped together around glial fibrillary acidic protein (GFAP) and water channel protein aquaporin 4 (AQP4) to form functional networks, regulate hydromineral balance across cell membranes and maintain the integrity of the BBB. Intense ischemic challenges can disrupt these capacities of astrocytes and result in their maladaptation. The maladapted astrocytic plasticity in ischemic stroke cannot only disrupt the hydromineral homeostasis across astrocyte membrane and the BBB, but also leads to disorders of the whole neurovascular unit.

    Purpose: To confirm the cortical thickness difference across the central sulcus (CS) visualized in the presence of vasogenic edema on MRI. Materials and methods: T2-weighted images of 70 cerebral hemispheres showing vasogenic edema infiltrating into subcortical white matter around the CS were studied retrospectively. Two neuroradiologists measured the cortical thickness of the anterior and posterior banks of the CS, precentral sulci (PrCS), and postcentral sulci (PoCS). Additionally, we compared the cortical thickness of the anterior and posterior banks of each sulcus visually using a grading scale. Results: On T2-weighted images, the cerebral cortex was highlighted by a high signal-intensity vasogenic edema in the adjacent white matter, and its thickness was readily measurable. The unique cortical thickness difference between the anterior and posterior banks of the CS were confirmed with measurements of 2.67 and 1.48 mm (p < 0.0001). The cortical measurements across other cerebral sulci were 2.04 and 1.95 mm (NS) for the PrCS, and 1.67 and 1.77 mm (NS) for the PoCS. The cortical thickness ratios were 1.86 for the CS, 1.05 for the PrCS, and 0.96 for the PoCS. On visual evaluation, the anterior bank of the CS was thicker than the posterior bank in 93% (65/70). For the PrCS and PoCS, the thickness of the anterior and posterior banks appeared to be equal in over 70% of the patients. Conclusion: A prominent cortical thickness difference across the CS in the presence of vasogenic edema was confirmed. This finding is considered to facilitate the identification of the CS in patients with brain tumors.

    Full Text Available Hidetaka Noma,1 Hiroshi Shimizu,1 Tatsuya Mimura21Department of Ophthalmology, Yachiyo Medical Center, Tokyo Women's Medical University, 2Department of Ophthalmology, Medical Center East, Tokyo Women's Medical University, Tokyo, JapanAbstract: Central retinal vein occlusion (CRVO is frequent in patients with systemic lupus erythematosus (SLE, but the treatment of the macular edema with this disease is extremely difficult. We report a case of cystoid macular edema (CME secondary to unilateral CRVO in a patient with SLE that responded to intravitreous injection of an anti-vascular endothelial growth factor (VEGF agent. A 33-year-old Japanese woman was referred to our department with unilateral impairment of vision. Microperimetry (MP-1 showed a cessation of foveal sensitivity. Fluorescein angiography showed CME without ischaemia of the macular region or peripheral retina (nonischemic CRVO. A diagnosis of CME and unilateral nonischemic CRVO combined with SLE was made and intravitreous anti-VEGF therapy was given. A sample of aqueous humor was harvested at the start of intravitreous injection after obtaining informed consent. Then the levels of VEGF and monocyte chemotactic protein (MCP-1 were measured in the aqueous humor by enzyme-linked immunosorbent assay, revealing that VEGF was 234 pg/mL and MCP-1 was 501 pg/mL. Two weeks later, left eye vision improved to 20/20. Optical coherence tomography (OCT showed considerable amelioration of retinal swelling and CME. MP-1 showed a marked increase of foveal sensitivity. However, she had recurrence of edema 3 months later. After harvesting aqueous humor again, intravitreous injection of an anti-VEGF agent was repeated for CME. The aqueous VEGF and MCP-1 levels were 156 pg/mL and 360 pg/mL, respectively. These findings suggest that inflammation was improved by intravitreous injection of bevacizumab. Intravitreous injection of anti-VEGF agents may be effective for CME due to nonischemic CRVO in SLE patients

    Full Text Available OBJECTIVE: To identify potential prognostic factors for neonatal mortality among newborns referred to intensive care units. METHODS: A live-birth cohort study was carried out in Goiânia, Central Brazil, from November 1999 to October 2000. Linked birth and infant death certificates were used to ascertain the cohort of live born infants. An additional active surveillance system of neonatal-based mortality was implemented. Exposure variables were collected from birth and death certificates. The outcome was survivors (n=713 and deaths (n=162 in all intensive care units in the study period. Cox's proportional hazards model was applied and a Receiver Operating Characteristic curve was used to compare the performance of statistically significant variables in the multivariable model. Adjusted mortality rates by birth weight and 5-min Apgar score were calculated for each intensive care unit. RESULTS: Low birth weight and 5-min Apgar score remained independently associated to death. Birth weight equal to 2,500g had 0.71 accuracy (95% CI: 0.65-0.77 for predicting neonatal death (sensitivity =72.2%. A wide variation in the mortality rates was found among intensive care units (9.5-48.1% and two of them remained with significant high mortality rates even after adjusting for birth weight and 5-min Apgar score. CONCLUSIONS: This study corroborates birth weight as a sensitive screening variable in surveillance programs for neonatal death and also to target intensive care units with high mortality rates for implementing preventive actions and interventions during the delivery period.OBJETIVO: Identificar fatores prognósticos de mortalidade neonatal em unidades de cuidados intensivos.

    Full Text Available Introduction: The PICC (peripherally inserted central catheter is a long flexible catheter which is inserted through a peripheral vein, progresses through a needle introducer until the final portion of the vena cava, acquiring characteristics of a central catheter. Objective: To point out the main theoretical and scientific ideas that demonstrate the reliability, competence and ability of nurses to perform the PICC. Methodology: Systematic review of articles, which were found by searching the database scientific journals and bibliographies area. Results: The success of integration depends on the patient assessment and choice of venous access where the catheter will be positioned, and its tip should be in the middle third of the superior vena cava, or the middle third of the inferior vena cava. In neonates, which are used more frequently, proper positioning of the catheter is through nursing care in making the dressing, and the first 24 hours it should be compressive. Ideally, the PICC remains in the vein for periods longer than seven days or until the end of treatment, thus decreasing invasive procedures. Conclusion: According to the Federal Board of Nursing (COFEN, it is lawful for the insertion of PICC nurses, provided it has undergone professional training.

    Peripherally inserted central catheters (PICCs) are widely used in the pediatric population, and their use continues to grow in popularity. These catheters provide a reliable source of venous access to neonatal patients but can also be the cause of life-threatening complications. There are several well-documented complications such as infections, catheter thrombosis, vascular extravasations, and fractured catheters. However, the complication of vascular erosion into the pleural space using both small and silicone-based catheters is rarely described. After obtaining institutional review board approval, we identified 4 cases to review of PICCs complicated by vascular erosions in the past 2 years. Herein, we also review the current literature of PICC complications. Getting the catheter tip as close to the atrial-caval junction as possible and confirmation of this placement are of the utmost importance. The thick wall of the vena cava near the atrium seems to be less likely to perforate; in addition, this position provides increased volume and turbulence to help dilute the hyperosmolar fluid, which seems to also be a factor in this complication. A daily screening chest x-ray in patients with upper extremity PICCs and ongoing parenteral nutrition (PN) are not necessary at this time given the overall low rate of vascular erosion and concerns regarding excessive radiation exposure in pediatric populations. However, a low threshold for chest x-ray imaging in patients with even mild respiratory symptoms in the setting of upper extremity PN is recommended. PMID:25700180

    Germinal matrix hemorrhage (GMH) is the most common neurological disease of premature newborns leading to detrimental neurological sequelae. Minocycline has been reported to play a key role in neurological inflammatory diseases by controlling some mechanisms that involve cannabinoid receptor 2 (CB2R). The current study investigated whether minocycline reduces neuroinflammation and protects the brain from injury in a rat model of collagenase-induced GMH by regulating CB2R activity. To test this hypothesis, the effects of minocycline and a CB2R antagonist (AM630) were evaluated in male rat pups that were post-natal day 7 (P7) after GMH. We found that minocycline can lead to increased CB2R mRNA expression and protein expression in microglia. Minocycline significantly reduced GMH-induced brain edema, microglial activation, and lateral ventricular volume. Additionally, minocycline enhanced cortical thickness after injury. All of these neuroprotective effects of minocycline were prevented by AM630. A cannabinoid CB2 agonist (JWH133) was used to strengthen the hypothesis, which showed the identical neuroprotective effects of minocycline. Our study demonstrates, for the first time, that minocycline attenuates neuroinflammation and brain injury in a rat model of GMH, and activation of CBR2 was partially involved in these processes.

    Macular edema (ME) and central serous retinopathy (CSR) are two macular diseases that affect the central vision of a person if they are left untreated. Optical coherence tomography (OCT) imaging is the latest eye examination technique that shows a cross-sectional region of the retinal layers and that can be used to detect many retinal disorders in an early stage. Many researchers have done clinical studies on ME and CSR and reported significant findings in macular OCT scans. However, this paper proposes an automated method for the classification of ME and CSR from OCT images using a support vector machine (SVM) classifier. Five distinct features (three based on the thickness profiles of the sub-retinal layers and two based on cyst fluids within the sub-retinal layers) are extracted from 30 labeled images (10 ME, 10 CSR, and 10 healthy), and SVM is trained on these. We applied our proposed algorithm on 90 time-domain OCT (TD-OCT) images (30 ME, 30 CSR, 30 healthy) of 73 patients. Our algorithm correctly classified 88 out of 90 subjects with accuracy, sensitivity, and specificity of 97.77%, 100%, and 93.33%, respectively. PMID:27140751

    We report a case of neonatal herpes simplex virus (HSV)-1 central nervous system disease with bilateral acute retinal necrosis (ARN). An infant was presented at 17 days of age with focal seizures. Cerebrospinal fluid polymerase chain reaction was positive for HSV-1 and brain magnetic resonance imaging showed cerebritis. While receiving intravenous acyclovir therapy, the infant developed ARN with vitreous fluid polymerase chain reaction positive for HSV-1 necessitating intravitreal foscarnet therapy. This is the first reported neonatal ARN secondary to HSV-1 and the first ARN case presenting without external ocular or cutaneous signs. Our report highlights that infants with neonatal HSV central nervous system disease should undergo a thorough ophthalmological evaluation to facilitate prompt diagnosis and immediate treatment of this rapidly progressive sight-threatening disease.

    Amelie Pielen

    Full Text Available BACKGROUND: Intravitreal agents have replaced observation in macular edema in central (CRVO and grid laser photocoagulation in branch retinal vein occlusion (BRVO. We conducted a systematic review to evaluate efficacy and safety outcomes of intravitreal therapies for macular edema in CRVO and BRVO. METHODS AND FINDINGS: MEDLINE, Embase, and the Cochrane Library were systematically searched for RCTs with no limitations of language and year of publication. 11 RCTs investigating anti-VEGF agents (ranibizumab, bevacizumab, aflibercept and steroids (triamcinolone, dexamethasone implant with a minimum follow-up of 1 year were evaluated. EFFICACY CRVO: Greatest gain in visual acuity after 12 months was observed both under aflibercept 2 mg: +16.2 letters (8.5 injections, and under bevacizumab 1.25 mg: +16.1 letters (8 injections. Ranibizumab 0.5 mg improved vision by +13.9 letters (8.8 injections. Triamcinolone 1 mg and 4 mg stabilized visual acuity at a lower injection frequency (-1.2 letters, 2 injections. BRVO: Ranibizumab 0.5 mg resulted in a visual acuity gain of +18.3 letters (8.4 injections. The effect of dexamethasone implant was transient after 1.9 implants in both indications. SAFETY: Serious ocular adverse events were rare, e.g., endophthalmitis occurred in 0.0-0.9%. Major differences were found in an indirect comparison between steroids and anti-VEGF agents for cataract progression (19.8-35.0% vs. 0.9-7.0% and in required treatment of increased intraocular pressure (7.0-41.0% vs. none. No major differences were identified in systemic adverse events. CONCLUSIONS: Anti-VEGF agents result in a promising gain of visual acuity, but require a high injection frequency. Dexamethasone implant might be an alternative, but comparison is impaired as the effect is temporary and it has not yet been tested in PRN regimen. The ocular risk profile seems to be favorable for anti-VEGF agents in comparison to steroids. Because comparative data from head

  3. A new algorithm for detecting central apnea in neonates

    International Nuclear Information System (INIS)

    Apnea of prematurity is an important and common clinical problem, and is often the rate-limiting process in NICU discharge. Accurate detection of episodes of clinically important neonatal apnea using existing chest impedance (CI) monitoring is a clinical imperative. The technique relies on changes in impedance as the lungs fill with air, a high impedance substance. A potential confounder, however, is blood coursing through the heart. Thus, the cardiac signal during apnea might be mistaken for breathing. We report here a new filter to remove the cardiac signal from the CI that employs a novel resampling technique optimally suited to remove the heart rate signal, allowing improved apnea detection. We also develop an apnea detection method that employs the CI after cardiac filtering. The method has been applied to a large database of physiological signals, and we prove that, compared to the presently used monitors, the new method gives substantial improvement in apnea detection.

    Full Text Available Background: Percutaneous central venous cannulation (CVC in infants and children is a challenging procedure, and it is usually achieved with a blinded, external landmark-guided technique. Recent guidelines from the National Institute for Clinical Excellence (NICE recommend the use of ultrasound guidance for central venous catheterization in children. The purpose of this study was to evaluate this method in a pediatric and neonatal intensive care unit, assessing the number of attempts, access time (skin to vein, incidence of complication, and the ease of use for central venous access in the neonatal age group. Methods: After approval by the local departmental ethical committee, we evaluated an ultrasound-guided method over a period of 6 months in 20 critically ill patients requiring central venous access in a pediatric intensive care unit and a neonatal intensive care unit (median age 9 (0-204 months and weight 9.3 (1.9-60 kg. Cannulation was performed after locating the puncture site with the aid of an ultrasound device (8 MHz transducer, Vividi General Electrics® Burroughs, USA covered by a sterile sheath. Outcome measures included successful insertion rate, number of attempts, access time, and incidence of complications. Results: Cannulation of the central vein was 100% successful in all patients. The right femoral vein was preferred in 60% of the cases. The vein was entered on the first attempt in 75% of all patients, and the median number of attempts was 1. The median access time (skin to vein for all patients was 64.5 s. No arterial punctures or hematomas occurred using the ultrasound technique. Conclusions: In a sample of critically ill patients from a pediatric and neonatal intensive care unit, ultrasound-guided CVC compared with published reports on traditional technique required fewer attempts and less time. It improved the overall success rate, minimized the occurrence of complications during vein cannulation and was easy to apply in

    The physician who deals with pulmonary edema from a pathophysiologic basis will seldom make a diagnostic or therapeutic error. Recent additions to preload and afterload therapy have greatly helped in the emergency and ambulatory treatment of pulmonary edema due to left heart failure. Careful follow-up and patient self-monitoring are the most effective means of reducing hospitalization of chronic heart failure patients.

    Full Text Available Objective: Several studies dealt with factors associated with childhood mortality, especially in developing countries, but less is known about former communistic countries. We therefore analyzed the factors affecting mortality rates among children in the Central Asian countries Kyrgyzstan, Kazakhstan and Uzbekistan. We focused on the impact of living place (rural versus urban and age dependency (neonatal versus under-three mortality on the mortality risk. Methods: We used the Demographic and Health Surveys data (DHS for the three Central Asian countries. The combined data set included information about 2867 children under the age of three, 135 of whom died. We studied three multiple logistic regression models: for the mortality under the age of three, for neonatal mortality (1st month of life and for mortality in 2nd-36th month of life. Results: Under-three mortality was independently associated with living in a rural versus urban area (OR 1.69 (CI 1.11-2.56, birth order and mother not being currently married vs. married (OR 0.52 (CI 0.25-1.08. There was a lower risk of mortality for children living in larger families (six or more household members vs. less than six, OR 0.45 (CI 0.30-0.65. Living in a rural area was more strongly associated with mortality in 2-36 month of life than with neonatal mortality. Differences between countries were greater in neonatal mortality than in mortality between 2nd-36th month of life. Conclusions: This study suggests that urban-rural differences with respect to childhood mortality in these countries persist after adjusting for several socioeconomic factors.

    Percutaneously inserted central venous catheters (PICCs) have been used to provide central venous access for more than 25 years. Although these lines initially were placed by physicians, currently there are many adult, pediatric, and neonatal nurse-based PICC teams. This article describes the inception and growth of 1 team which, during the last 14 years, has placed more than 3400 catheters and trained more than 50 bedside nurses to insert PICCs. It highlights the development of the team, including details of how team members were selected and trained. Management of ongoing issues was handled by a self-directed nurse team organized into a committee structure composed of an oversight committee and education, guideline, qualifications, and quality improvement subcommittees. This team set and achieved the goals of training bedside nurses to place PICCs, providing consistent management of PICCs, and closely monitoring outcomes. PMID:17536330

    Full Text Available Background and Objectives: Little is known about the natural history of neonates born in the rural and tribal areas in India. The Neonatal Disease Surveillance Study (NDSS measures the incidence of high-priority neonatal diseases, neonatal health events and associated risk factors to plan appropriate and effective actions. Materials and Methods: The NDSS is being conducted in Ramtek Revenue Block, Nagpur district, Maharashtra state, given its considerably high level of neonatal mortality. All households from five selected primary health centers were screened. Both active and passive surveillance systems were used for systematic collection of mother′s health during pregnancy and of baby′s health from birth to 4 months after birth. First-year results from November 2006 to October 2007 are presented. Results: Pregnancy outcomes were available for 1,136 women, with an overall neonatal mortality of 73 per 1,000 live births. The pregnancy outcomes varied by gestational age of the baby; miscarriages and abortions were higher in tribal than in non-tribal women, and tribal women had higher rates of low-birth weight (LBW neonates than non-tribal women. The main cause of neonatal mortality was LBW, followed by sepsis and respiratory illness. The mortality of non-tribal babies was most strongly associated with pre term. For tribal babies, mortality was also associated with maternal morbidity and delay in the initiation of breastfeeding. Interpretation and Conclusions: The NDSS provides valuable information on the potentially modifiable factors associated with increased likelihood of neonatal mortality and morbidity. The Neonatal Health Research Initiative is now developing community-based interventions to reduce the high rate of neonatal mortality and morbidity in the rural areas of India.

    Full Text Available Aim: To compare the effects of intravitrealbevacizumab (IVB and intravitreal triamcinolone acetonide (IVT in the treatment of macular edema (ME secondary to central retinal vein occlusion (CRVO. Materials and Methods: There were 20 patients treated with IVB (1.25 mg/0.05 mL and 16 treated with IVT (4 mg/0.1 mL. The two groups were compared with regard to best-corrected visual acuity (BCVA, central macular thickness (CMT on optical coherence tomography (OCT, slit-lamp biomicroscopy and fundus fluorescein angiography results, intraocular pressure (IOP, numbers of injections, and adverse events. Results: The mean follow-up times in the IVB and IVT groups were 17.45±8.1 months (range: 8-33 months and 19.94±10.59 months (range: 6-40 months, respectively (P = 0.431. Visual acuity increased and CMT decreased significantly within both groups, but no differences were observed between the groups (P = 0.718. The percentages of patients with increased IOP and iatrogenic cataracts were significantly higher in the IVT group than in the IVB group. Conclusions: Treatment with IVB and IVT both resulted in significant improvement in visual acuity and a decrease in CMT in patients with ME secondary to non-ischemic CRVO, with no difference between the two treatments. The incidence of adverse events, however, was significantly greater in the IVT group than in the IVB group. IVB may be preferred over IVT for the treatment of ME in patients with non-ischemic CRVO.

    Although enteroviruses generally cause asymptomatic or mild disease, neonates are at higher risk for severe illnesses, among which systemic disease characterized by multiorgan involvement is a potentially fatal condition. Enterovirus neonatal infections may be the source of nosocomial infections in neonatology or in pediatric intensive care units. We report central nervous system infections due to Echovirus 11 in two neonates and the molecular evidence of nosocomial transmission of this strain in a neonatal unit by enterovirus genotyping and phylogenetic analysis. This report illustrates the importance of including enterovirus genome detection in the sepsis screening concomitantly with bacteriological investigations performed at admission of a neonate. Rapid diagnosis and subsequent genotyping could have a beneficial impact on clinical practices at the individual level (reducing the length of antibiotic therapy) and public health policy at the collective level by reinforcing hygiene measures to prevent nosocomial infections, with nurseries and neonatal units being at greater risks.

    Full Text Available PURPOSE: The aim of the present study is to assess central corneal edema and visual recovery after cataract surgery performed according to two technologies: conventional ultrasonic and liquefaction (Aqualase®. METHODS:This is a prospective contralateral study in wich 20 patients with comparable preoperative conditions were submitted to cataract surgery were evaluated. Preoperative assessment involved complete ophthalmological examination and the study included patients with bilateral cataracts up to grade 2, according to the Lens Opacity Classification System II. The same cristaline fracture technique was used in all cases, and surgical procedures were performed by the same experienced surgeon, using two technologies: liquefaction or conventional phacoemulsification. Postoperative central corneal edema was measured by corneal optical pachymetry (Orbscan II® on the 1st, 3rd, 7th and 10th postoperative days. RESULTS:None of the 20 patients submitted to surgery was lost during the postoperative follow-up or excluded from the analysis. On the first postoperative, the visual acuity average was 0.031 logMAR in the Aqualase® group and 0.043 logMAR in the conventional surgery group. No statistical difference was detected in the assessment of visual acuity throughout the postoperative period. Central corneal pachymetry varied from 543.93 + 34.69 preoperatively to 545.08 ± 25.67 on the last day of follow-up in the Aqualase® group, and from 543.13 + 30.62 to 536.08 + 34.89 in the conventional technique group, without statistical significance. CONCLUSION:This study suggests that both techniques are equally effective for surgery on lenses with grade I or II cataract, and that they provide similar results in terms of visual recovery and central corneal edema.OBJETIVO: Avaliar o edema corneano central e a recuperação visual após cirurgia de catarata realizada através de duas tecnologias: ultrassônica convencional e liquefação (Aqualase®.

    Presented here is a case of unilateral pulmonary edema following acute subglottic edema after removal of an endotracheal tube. A 3-year-old boy, diagnosed as having nondiphtheric croup and pectus excavatum deformity, was scheduled for repair of a cleft lip. No complication occurred during the operation. After removal of the endotracheal tube, he showed dyspnea and cyanosis and was later found to have acute subglottic edema. After reintubation of the trachea, frothy pink fluid was discharged from the tube, and chest roentgenogram showed a right-sided alveolar infiltrate. Many factors may cause unilateral pulmonary edema, but it is suggested that acute subglottic edema and unilateral bronchial fragility strongly affected this episode.

    Full Text Available Abstract Background Worldwide 15.5% of neonates are born with low birth weight, 95.6% of them in the developing countries. Prematurity accounts for 10% of neonatal mortality globally. The purpose of this study was to evaluate the effects of birth weight and gender on neonatal outcome. Findings The data of 278 neonates managed in the Special Care Baby Unit (SCBU of Jos University Teaching Hospital (JUTH over a 2 year period from July 2006 to June 2008 were analyzed. One hundred and fifty nine (57.2% were males and 119(42.8% females. There were 87(31.3% preterm and 191 (68.7% term babies. Twelve of the babies died. Seven (2.52% and 5 (1.80% being males and females respectively. The neonatal mortality rate by gender was not significant (p > 0.05. The neonatal mortality was 25.2 deaths per 1000 live births for boys and 18.0 for girls. The mean birth weights of the preterm and term babies were 1.88 ± 0.47 kg and 3.02 ± 0.50 kg respectively, with a mean gestational age of 30.62 ± 3.65 weeks and 38.29 ± 0.99 weeks respectively. Eighty seven (31.3% of the babies were of low birth weight, 188(67.6% were of normal birth weight and 3(1.1% high birth weight. Of the low birth weight babies, 6(2.2% were term small for gestational age. Six (2.2% of the preterm infants had normal birth weight. Eleven of the babies that died were preterm low birth weight. The overall mortality rate was 4.32%. The birth weight specific mortality rate was 126 per 1000 for the preterm low birth weight and 5 per 1000 for the term babies. Birth weight unlike gender is a significant predictor of mortality, mortality being higher in neonates of The subjects showed one or more major clinical indications for admission. The major clinical indications for the preterm and term babies were respectively as follows: neonatal sepsis 63(22.7% and 124(44.6%; neonatal jaundice 32(11.1% and 71(24.7%; malaria 9(3.1% and 13(4.5%; birth asphyxia 3(1.0% and 7(2.4%.

Nfs (called fail-safe number was calculated to evaluate the publication bias. RESULTS: We included 5 trials consisting 323 cases and 281 controls. Primary outcomes showed that overall comparison of anti-VEGF agents with placebo control yielded a 374% and 136% increased tendency for a gain of 15 letters or more on Early Treatment Diabetic Retinopathy Study (ETDRS chart (95% confidence interval [95% CI]: 2.43-9.23; P<0.00001; I(2 = 59%, 95% CI: 1.60-3.49; P<0.0001; I(2  = 0%, respectively at 6 and 12 months. Secondary outcomes showed that a 90% and 77% decreased risk at 6 and 12 months for a loss of 15 letters or more. The overall mean difference showed a statistically significance in best-corrected visual acuity (BCVA on each time point. However, changes of central retinal thickness (CRT lost significance at 12 months after 6-month as-needed treatment. The incidence of adverse events (AEs had no statistical difference between anti-VEGF and placebo groups. Subgroup analyses indicated that patients receiving Aflibercept got the highest tendency to gain 15 letters or more (OR = 9.78; 95% CI: 4.43-21.56; P<0.00001. Age controlled analysis suggested a weaken tendency of BCVA improvement in age over 50 (MD = 12.26; 95% CI: 7.55-16.98; P<0.00001. Subgroup analysis by clinical classification showed a strengthen difference of BCVA changes at 6 months in ischemic type (MD = 19.65 letters, 95% CI: 13.15 to 26.14 letters, P<0.00001.

    Most physiological behaviors such as food intake are controlled by the hypothalamus and its nuclei. It has been demonstrated that injection of the paraventricular nucleus of the hypothalamus with nitric oxide (NO) donors elicited changes in the concentration of some amino acids, including GABA. Also, central nitrergic and GABAergic systems are known to provide inputs to the paraventricular nucleus and are involved in food intake control. Therefore, the present study examines the probable interaction of central nitrergic and GABAergic systems on food intake in neonatal layer-type chicks. The results of this study showed that intracerebroventricular (ICV) injection of L-arginine (400 and 800 nmol), as a NO donor, significantly decreased food intake (P baclofen (0.2 µg), a GABAB agonist, did not change in ICV co-injection of L-arginine (200 nmol) or L-NAME (100 nmol) with baclofen (0.2 µg) (P > 0.05). Also, the hypophagic effect of L-arginine (800 nmol) was significantly amplified in ICV co-injection of picrotoxin (0.5 µg), a GABAA antagonist, or CGP54626 (21 ng), a GABAB antagonist, with L-arginine (800 nmol) (P < 0.001). These results probably suggest an interaction of central nitrergic and GABAergic systems on food intake in neonatal layer-type chicks and GABAA receptors play a major role in this interaction.

    The decrease of lung compliance in pulmonary edema underlies ventilator-induced lung injury. However, the cause of the decrease in compliance is unknown. We tested the hypothesis that in pulmonary edema, the mechanical effects of liquid-filled alveoli increase tissue stress in adjacent air-filled alveoli. By micropuncture of isolated, perfused rat lungs, we established a single-alveolus model of pulmonary edema that we imaged using confocal microscopy. In this model, we viewed a liquid-filled...

    1990-01-01

    A percutaneous 27-gauge OD central venous catheter was inserted at 4 +/- 3 (SD) days of age and left in place for up to 2 weeks in 20 neonates with birth weights less than 1200 g and greater than 24 h of age. Parenteral nutritional solutions and medications were administered through these catheters. Twenty neonates matched for birth weight and gestational age served as paired controls. In vitro studies demonstrate that the maximum infusion rate for parenteral nutrition solutions is about 20 ml/hr. Packed red blood cells could not be infused through these catheters. In vivo results demonstrate a significant (p less than 0.05) reduction in number of peripheral iv catheters inserted during study (2 +/- 1 vs 7 +/- 4, SD) with no difference in cost per day of iv access ($79.42 +/- 113.51 vs $43.91 +/- 15.99, SD). Two-dimensional ultrasound assessment of catheter thrombosis was unsuccessful. Moreover, there was no correlation between angiographic and electron microscopic evaluation of catheter tip thrombosis. Electron microscopy of catheter tips revealed 33% with complete, partial and no occlusion, respectively, and 39% with sheath thrombosis. In summary, percutaneous insertion of a 27-gauge OD Vialon central venous catheter is a feasible alternative in providing venous access in very low birth weight infants. PMID:2112646

  13. A clinical tool for reducing central nervous system depression among neonates exposed to codeine through breast milk.

    Directory of Open Access Journals (Sweden)

    Lauren E Kelly

    Full Text Available BACKGROUND: Neonates are commonly exposed to maternal codeine through breast milk. Central Nervous System (CNS depression has been reported in up to 24% of nurslings following codeine exposure. In 2009, we developed guidelines to improve the safety of codeine use during breastfeeding based on previously established pharmacogenetic and clinical risk factors. The primary objective of this study was to prospectively evaluate the effectiveness of these guidelines in ensuring neonatal safety. METHODS AND FINDINGS: Women taking codeine for pain following caesarean section were given safety guidelines, including advice to use the lowest codeine dose for no longer than four days and to switch to a non-opioid when possible. Mothers provided a saliva sample for analysis of genes involved in opioid disposition, metabolism and response. A total of 238 consenting women participated. Neonatal sedation was reported in 2.1% (5/238 of breastfeeding women taking codeine according to our safety guidelines. This rate was eight fold lower than that reported in previous prospective studies. Women reporting sedated infants were taking codeine for a significantly longer period of time (4.80±2.59 days vs. 2.52±1.58 days, p = 0.0018. While following the codeine safety guidelines, mothers were less likely to supplement with formula, reported lower rates of sedation in themselves and breastfed more frequently throughout the day when compared to previously reported rates. Genotyping analysis of cytochrome p450 2D6 (CYP2D6, uridine-diphosphate glucuronosyltransferase (UGT 2B7, p-glycoprotein (ABCB1, the mu-opioid receptor (OPRM1 and catechol-o-demethyltransferase (COMT did not predict codeine response in breastfeeding mother/infant pairs when following the safety guidelines. CONCLUSIONS: The only cases of CNS depression occurred when the length of codeine use exceeded the guideline recommendations. Neonatal safety of codeine can be improved using evidence

    In most cases, diabetic macular edema is treated successfully with central laser photocoagulation. However, only few studies report such favorable results in cystoid macular edema, which has a poor visual prognosis. In the present prospective study on diabetics with cystoid macular edema, aged less than 40 years, a better visual outcome was obtained in patients treated with prostaglandin synthesis inhibitors than in an untreated group.

    Context Coriandrum sativum L. (Apiaceae) (coriander) is an herb grown throughout the world as a culinary, medicinal or essential crop. In traditional medicine, it is used for the relief of anxiety and insomnia. Systemic hydro-alcoholic and aqueous extract from aerial parts and seeds had anxiolytic and sedative action in rodents, but little is known about its central effect in chicks. Objective To study the effects of intracerebroventricular administration of essential oil from coriander seeds and its major component linalool on locomotor activity and emotionality of neonatal chicks. Materials and methods The chemical composition of coriander essential oil was determined by a gas-chromatographic analysis (> 80% linalool). Behavioural effects of central administration of coriander oil and linalool (both at doses of 0.86, 8.6 and 86 μg/chick) versus saline and a sedative diazepam dose (17.5 μg/chick, standard drug) in an open field test for 10 min were observed. Results Doses of 8.6 and 86 μg from coriander oil and linalool significantly decreased (p linalool, which also induced a similar sedative effect, and, therefore, could be considered as a potential therapeutic agent similar to diazepam.

    Despite the fact that it has been used since the 1960s in diseases associated with brain edema and has been investigated in >150 publications on head injury, very little has been published on the outcome of osmotherapy. We can only speculate whether osmotherapy improves outcome, has no effect......, osmotherapy can be negative for outcome, which may explain why we lack scientific support for its use. These drawbacks, and the fact that the most recent Cochrane meta-analyses of osmotherapy in brain edema and stroke could not find any beneficial effects on outcome, make routine use of osmotherapy in brain...... edema doubtful. Nevertheless, the use of osmotherapy as a temporary measure may be justified to acutely prevent brain stem compression until other measures, such as evacuation of space-occupying lesions or decompressive craniotomy, can be performed.

  4. Neonatal head ultrasound: systematic approach to congenital Central Nervous System anomalies. A pictorial essay.

    Science.gov (United States)

    Yoon, Hye-Kyung; Cho, Seong Whi

    2016-09-01

    Brain ultrasound is widely used for the screening of prematurely born babies. Although the best imaging modality for the central nervous system anomaly is brain MRI, the first imaging study in the post-natal period is brain ultrasonography in most cases. Anomalies could be found incidentally on screening ultrasound, or in those cases already suspected on prenatal ultrasound. In order not to miss congenital structural abnormalities of the brain on screening ultrasound, systematic approaches would be very helpful. The ventricles and sylvian fissures are very important structures to suspect central nervous system anomalies: they are symmetric structures so we should look for any asymmetry or maldevelopment. And then, on sagittal images, the midline structures including the corpus callosum and cerebellar vermis should be observed carefully. Finally, we should look for any abnormality in gyration or cortical development. Skull defect with herniation of intracranial contents, a spectrum of encephalo-meningocele, could be also identified on ultrasound. Congenital infections such as cytomegalovirus infection may show ventriculomegaly and malformation of the cortical development on imaging studies. PMID:27622417

  6. Reperfusion pulmonary edema

    International Nuclear Information System (INIS)

    Reperfusion following lower-torso ischemia in humans leads to respiratory failure manifest by pulmonary hypertension, hypoxemia, and noncardiogenic pulmonary edema. The mechanism of injury has been studied in the sheep lung lymph preparation, where it has been demonstrated that the reperfusion resulting in pulmonary edema is due to an increase in microvascular permeability of the lung to protein. This respiratory failure caused by reperfusion appears to be an inflammatory reaction associated with intravascular release of the chemoattractants leukotriene B4 and thromboxane. Histological studies of the lung in experimental animals revealed significant accumulation of neutrophils but not platelets in alveolar capillaries. The authors conclude that thromboxane generated and released from the ischemic tissue is responsible for the transient pulmonary hypertension. Second, it is likely that the chemoattractants are responsible for leukosequestration, and third, neutrophils, oxygen-derived free radicals, and thromboxane moderate the altered lung permeability

    2015-01-01

    Neonatal teeth is a rare disorder of tooth eruption, arising in the oral cavity, usually in the anterior mandible, in the first month of life. Its etiology is unknown. This condition can cause breastfeeding difficulties, besides aspiration or swallowing of the teeth. We describe the case of a premature infant in the second day of life presented with gingival edema, redness and discrete swelling in the region of the mandibular central incisors. Ten days later, two small teeth with hypermobility were detected. Extraction of those teeth was performed. With this clinical case we intend to show the rarity of this entity, especially in premature infants, the possible association with various syndromes and the need for a multifactorial approach to the treatment decision (extraction / conservative treatment).

    Neonatal sepsis is the most common cause of neonatal deaths with high mortality despite treatment. Neonatal sepsis can be classified into two subtypes depending upon onset of symptoms. There are many factors that make neonates more susceptable to infection. Signs of sepsis in neonates are often non-specific and high degree of suspicion is needed for early diagnosis. Some laboratory parameters can be helpful for screening of neonates with neonatal sepsis, but none of it is specific and sensiti...

    2003-01-01

    Full Text Available Reexpansion pulmonary edema (RPE is a rare, but frequently lethal, clinical condition. The precise pathophysiologic abnormalities associated with this disorder are still unknown, though decreased pulmonary surfactant levels and a pro-inflammatory status are putative mechanisms. Early diagnosis is crucial, since prognosis depends on early recognition and prompt treatment. Considering the high mortality rates related to RPE, preventive measures are still the best available strategy for patient handling. This review provides a brief overview of the pathophysiology, diagnosis, treatment, and prevention of RPE, with practical recommendations for adequate intervention.

  11. Diabetic Macular Edema

    Science.gov (United States)

    Lobo, Conceição; Pires, Isabel; Cunha-Vaz, José

    The optical coherence tomography (OCT), a noninvasive and noncontact diagnostic method, was introduced in 1995 for imaging macular diseases. In diabetic macular edema (DME), OCT scans show hyporeflectivity, due to intraretinal and/or subretinal fluid accumulation, related to inner and/or outer blood-retinal barrier breakdown. OCT tomograms may also reveal the presence of hard exudates, as hyperreflective spots with a shadow, in the outer retinal layers, among others. In conclusion, OCT is a particularly valuable diagnostic tool in DME, helpful both in the diagnosis and follow-up procedure.

    Preterm birth represents a high risk of neurodevelopmental disabilities when associated with white-matter damage. Recent studies have reported cognitive deficits in children born preterm without brain injury on MRI at term-equivalent age. Understanding the microstructural and metabolic underpinnings of these deficits is essential for their early detection. Here, we used diffusion-weighted imaging and single-voxel 1H magnetic resonance spectroscopy (MRS) to compare brain maturation at term-equivalent age in premature neonates with no evidence of white matter injury on conventional MRI except diffuse excessive high-signal intensity, and normal term neonates. Thirty-two infants, 16 term neonates (mean post-conceptional age at scan: 39.8±1 weeks) and 16 premature neonates (mean gestational age at birth: 29.1±2 weeks, mean post-conceptional age at scan: 39.2±1 weeks) were investigated. The MRI/MRS protocol performed at 1.5T involved diffusion-weighted MRI and localized 1H-MRS with the Point RESolved Spectroscopy (PRESS) sequence. Preterm neonates showed significantly higher ADC values in the temporal white matter (Pglutamine+glutamate)/H2O ratios (Pglutamine plus glutamate, and macromolecules in the centrum semiovale, a finding suggesting altered energy metabolism and protein synthesis.

    Sarkadi-Nagy Eszter A

    2005-06-01

    Full Text Available Abstract Background Docosahexaenoic acid (DHA and arachidonic acid (ARA are major components of the cerebral cortex and visual system, where they play a critical role in neural development. We quantitatively mapped fatty acids in 26 regions of the four-week-old breastfed baboon CNS, and studied the influence of dietary DHA and ARA supplementation and prematurity on CNS DHA and ARA concentrations. Methods Baboons were randomized into a breastfed (B and four formula-fed groups: term, no DHA/ARA (T-; term, DHA/ARA supplemented (T+; preterm, no DHA/ARA (P-; preterm and DHA/ARA supplemented (P+. At four weeks adjusted age, brains were dissected and total fatty acids analyzed by gas chromatography and mass spectrometry. Results DHA and ARA are rich in many more structures than previously reported. They are most concentrated in structures local to the brain stem and diencephalon, particularly the basal ganglia, limbic regions, thalamus and midbrain, and comparatively lower in white matter. Dietary supplementation increased DHA in all structures but had little influence on ARA concentrations. Supplementation restored DHA concentrations to levels of breastfed neonates in all regions except the cerebral cortex and cerebellum. Prematurity per se did not exert a strong influence on DHA or ARA concentrations. Conclusion 1 DHA and ARA are found in high concentration throughout the primate CNS, particularly in gray matter such as basal ganglia; 2 DHA concentrations drop across most CNS structures in neonates consuming formulas with no DHA, but ARA levels are relatively immune to ARA in the diet; 3 supplementation of infant formula is effective at restoring DHA concentration in structures other than the cerebral cortex. These results will be useful as a guide to future investigations of CNS function in the absence of dietary DHA and ARA.

These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    Traumatic brain injury is a heterogeneous disorder resulting from an external force applied to the head. The development of cerebral edema plays a central role in the evolution of injury following brain trauma and is closely associated with neurologic outcomes. Recent advances in the understanding of the molecular and cellular pathways contributing to the posttraumatic development of cerebral edema have led to the identification of multiple prospective therapeutic targets. The authors summarize the pathogenic mechanisms underlying cerebral edema and highlight the molecular pathways that may be therapeutically targeted to mitigate cerebral edema and associated sequelae following traumatic brain injury.

    Full Text Available Aim:We assessed late onset sepsis (LOS rates of neonates in a neonatal intensive care unit (NICU before and after implementing an evidence-based bundle to prevent these infections in a country with poor resources.Methods:We evaluate trends of LOS between October 2010 and August 2012 in a large tertiary hospital in Brazil. We designed a protocol based of CDC guidelines for insertion of maintenance of central venous catheter targeted to reduction of bloodstream infections. During this period two major events occurred: a great increase of LOS rates in January months and relocation of the unit to a provisory place. Additionally we evaluated the risk factors and etiology of these infections.Results:A total of 112 (20.3% cases defined as LOS were found. The overall incidence rate of LOS in the study was 16.1/1000 patient/days and 23.0/1000 CVC-days. Our monthly rates data of LOS/1000 patient-day reveal fluctuations over the studied period, with incidence rates of these infections in staff vacation period (January 2011 and 2012 significantly higher (59.6/1000 patients-days than compared with the other months rates (16.6/1000 patients-days (IRR = 3.59; p< 0.001. As opposite, the incidence rates of LOS during relocation period was lower (10.3/1000 patients-days when compared with baseline period 26.7/1000 patients-days (IRR = 2.59; p= 0.007. After the intervention period, these rates decreased in the post intervention period, when compared with preintervention 14.7/1000 patients-days and 23.4/1000 patients-days, respectively (IRR = 1.59; p= 0.04.Conclusion:Through simple infection control measures, LOS can be successfully controlled especially in NICUs of limited resources countries such as ours.

    Full Text Available The clinicopathological findings of cerebral edema were investigated in patients with acute hepatic failure autopsied at Okayama University Hospital between 1970 and 1980 retrospectively. Nine (64% of 14 hepatic failure cases were found to have cerebral edema during a post-mortem examination of the brain. Clinical features of the patients with cerebral edema were not significantly different from those of the patients without cerebral edema. However, general convulsions were observed more frequently in patients later found to have cerebral edema. Moreover, the length of time from deep coma to death was much shorter in the brain edema cases with cerebral herniation than without herniation.

    Full Text Available Background/Aim. The effect of drugs leaves permanent consequences on the brain, organic in type, followed by numerous manifestations, and it significantly affects the development of mental dysfunctions. The clinicians are often given a task to estimate a patient’s personality during treatment or during experts estimate of a drug addict. The aim of this research was to determine the differences, if any, in characteristics of addicts experience and personality traits in drug addicts with or without cerebral edema. Methods. The research was conducted on a sample of 252 male drug addicts, the average age of 23.3 (SD = 4.3 years. Cerebral edema was confirmed on magnetic resonance (MR images of the brain performed during the treatment of the addicts. The participants were tested by the psychologists using Minnesota Multiphasic Personality Inventory (MMPI-201 test, and the data were processed using canonical discriminate analysis within the SPSS program. The dependent variable in the study was cerebral edema. A block of independent variables, designed for the requirements of this study, consisted of two subgroups. The first one consisted of 12 variables describing the relevant characteristics of drug abuse. The second subgroup consisted of 8 psychopathological tendencies in the personality defined by the mentioned test. Results. Cerebral edema was confirmed in 52 (20.63% of the drug addicts. The differences between the groups of drug addicts with and without cerebral edema were determined in the following: the time span of taking drugs (0.301, use of alcohol parallel with drugs (0.466, and treatment for addiction (0.603. In the drug addicts with a cerebral edema, MMPI-201 confirmed the increase in the scales for hypochondria, psychopathic deviations and psychastenia, and the decrease in the scales for schizophrenia and depression. Conclusion. Our study confirmed a possible connection between cerebral edema and personality traits in a number of the

    Detection of an early stage of subglottic edema is vital for airway management and prevention of stenosis, a life-threatening condition in critically ill neonates. As an observer for the task of diagnosing edema in vivo, we investigated spatiotemporal correlation (STC) of full-range optical coherence tomography (OCT) images acquired in the rabbit airway with experimentally simulated edema. Operating the STC observer on OCT images generates STC coefficients as test statistics for the statistical decision task. Resulting from this, the receiver operating characteristic (ROC) curves for the diagnosis of airway edema with full-range OCT in-vivo images were extracted and areas under ROC curves were calculated. These statistically quantified results demonstrated the potential clinical feasibility of the STC method as a means to identify early airway edema.

    1986-02-01

    Permeability pulmonary edema was induced in ten rats by intravenous injection of oleic acid. Hydrostatic pulmonary edema was induced in another ten rats by continuous infusion of saline. Permeability pulmonary edema was detected as increased signal intensity in all animals on images obtained with repetition times (TR) of 2.0 sec and echo times (TE) of 28 and 56 msec. Hydrostatic pulmonary edema was perceivable only in seven of ten rats. It was best seen on spin-echo TR = 2.0 sec, TE = 28 msec images as increased intensity either throughout the whole lung or in a predominant central distribution. The slopes of the relationships between the mean signal intensity and water content of both lungs were lower for hydrostatic pulmonary edema than for permeability pulmonary edema. Hydrostatic pulmonary edema demonstrated similar T1 but markedly shorter T2 relaxation times than permeability edema. Magnetic resonance imaging can be used to estimate severity of hydrostatic and permeability pulmonary edemas. PMID:3941856

  19. Limb edemas in cancer patients

    International Nuclear Information System (INIS)

    Diagnostic radiology in cancer patients suffering from limb edemas serves two main purposes: to detect or to rule out lymph node metastases, recurrent cancer, or secondary malignancies, and to differentiate venous edema from lymphedema. The authors suggest an algorithmic pathway where the non-invasive imaging modalities, real-time ultrasonography and computed tomography are recommended as the initial diagnostic step. Both techniques are equally well suited to detect enlarged lymph nodes with high accuracy. In addition, computed tomography allows to a certain degree to separate venous from lymphedema. Phlebography is rarely needed in these patients. Lymphography should only be considered in patients undergoing microsurgical reconstructive operations of the lymphatics (e.g. lymphovenous anastomoses) because this invasive study carries the risk of deteriorating the edematous limb.

    1987-11-01

    We present the case of a 68-year-old woman with acute pulmonary edema secondary to the administration of naloxone to reverse an inadvertent narcotic overdose. The patient presented following a 12-hour history of increasingly bizarre behavior and confusion. A total IV dose of 1.6 mg naloxone was administered in an attempt to reverse the suspected overconsumption of a codeine-containing cough suppressant. She immediately became agitated, tachycardic, and diaphoretic; a clinical diagnosis of acute pulmonary edema was made. Following treatment with furosemide, nitroglycerin, and morphine sulfate, the patient recovered completely without further incident. Although naloxone is thought to be a safe drug with few complications, it should not be used indiscriminantly, and the smallest doses necessary to elicit the desired response should be used.

    Full Text Available Serotonin syndrome (SS is a potentially life-threatening condition resulting from excessive central and peripheral serotonergic activity. Clinically, it is a triad of mental-status changes, neuromuscular abnormalities, and autonomic disturbances. It can be caused by intentional self-poisoning, overdose, or inadvertent drug interactions. We report the case of a 58-year-old male with type 2 diabetes mellitus and obsessive compulsive disorder who developed pulmonary edema as a possible complication of SS. SS was caused by a combination of three specific serotonin re-uptake inhibitors (fluoxetine, fluvoxamine, and sertraline, linezolid, and fentanyl. The hospital course was further complicated by difficult weaning from the ventilator. SS was identified and successfully treated with cyproheptadine and lorazepam. The case highlights the importance of effective consultation-liaison and prompt recognition of SS as the presentation may be complex in the presence of co-morbid medical illness.

    1. A total of 488 pregnancies had the combination of two-plus or more proteinuria and edema of the hands and face. Of these, 208 were white and 280 were black gravidas. In the white gravidas, 8 fetal and neonatal deaths occurred with a perinatal mortality of 38.5 per 1,000. There were 13 perinatal deaths in the black subgroup with a perinatal mortality rate of 46.4 per 1,000. The overall perinatal mortality rate was 43.0 per 1,000, which could be compared to the overall perinatal mortality rate of 32.8 per 1,000 for the segment of the study population without edema or proteinuria. This underscored the implication of increased hazard to fetal outcome of these clinical signs in combination. 2. The analysis of the matrix data showed scattered rates throughout gestation in white median-age nulliparas. Their black counterparts had comparable increased mortality rates. In the white multiparas of ages 20 to 34 years, the highest rates were found at relatively low blood pressure levels. The black median-age multiparas had rates associated with higher pressure readings, especially at or above 125/75. In teenage mulliparas with edema and proteinuria, perinatal mortality rates were similar for both subgroups and were found in somewhat lower blood pressures. 3. The incremental analysis was remarkable in that rates were scattered widely in the white subgroups, but tightly clustered in the black subgroups. The black median-age nulliparas had perinatal mortality concentrated about 115 to 134 mm. Hg systolic and 65 to 84 mm. Hg diastolic. The overall mortality rates of this subgroup were the highest of the subgroups studied. The black 20 to 34 year old multiparas had highest coassociated deaths in the 134-154 mm. Hg systolic levels throughout pregnancy. The clustering effect was most pronounced in black teenage nulliparas in both systolic and diastolic blood pressure groups at much lower levels. 4.

    Full Text Available Rushmia Karim, Benjamin TangUniversity of Sydney School of Public Health, Concord Repatriation General Hospital, Concord, NSW, AustraliaBackground: Diabetic macular edema (DME is one of the manifestations of diabetic retinopathy leading to loss of central vision and visual acuity. It manifests itself with swelling around the central part of the retina, the area responsible for sharp vision. Current treatment includes laser therapy and intravitreal steroids with preventative measures including diabetes control. No one treatment has guaranteed control of diabetic macular edema which leads to deteriorating visual acuity, function and quality of life in patients. Vascular endothelial growth factor (VEGF has been shown to be a critical stimulus in the pathogenesis of macular edema secondary to diabetes.1 Antiangiogenic therapy encompassed treatment with anti-VEGF which inhibits VEGF-driven neovascularization hence macular edema leading to decreased visual acuity.Objective: For this review, we evaluated the effectiveness of intravitreal anti-VEGF in treating DME.Data sources: We identified five trials (n = 525 using electronic databases (Cochrane Central Register of Controlled Trials [Central], Medline®, and Excerpta Medica Database [EMBASE®] in October 2008, supplemented by hand searching of reference lists, review articles, and conference abstracts.Methods: We included all randomized clinical trials (RCTs evaluating any form of intravitreal anti-VEGF for treating DME. The main outcome factor was change in best-corrected visual acuity and central macular thickness. One author assessed eligibility, methodological quality, and extracted data. Meta analysis was performed when appropriate.Results: We included three trials of adequate methodological quality in our metaanalysis. Patients treated with anti-VEGF showed improvement in visual acuity of -0.17 (95% confidence interval [CI]: -0.23, -0.10 and central macular thickness -84.69 (95% CI: -117

  12. Bone marrow edema in sports: General concepts

    International Nuclear Information System (INIS)

    This paper will discuss the value of medical imaging in the detection and follow-up of bone marrow edema (BME), resulting from acute and chronic trauma in sports. MR imaging is the only imaging technique that allows direct evaluation of bone marrow edema in sports medicine. The use of fat suppressed T2-weighted or STIR images is particularly appropriate to detect bone marrow edema. The extent of bone marrow edema reflects the biomechanics of trauma. Compressive forces between two bony structures will result in extensive areas of bone marrow edema, whereas distraction forces provoke more subtle areas of bone marrow edema at the insertion of supporting structures of joints. In most clinical situations, a combination of compression and distraction forces is present, causing a complex pattern of bone marrow edema. A meticulous pattern approach of the distribution of these bone marrow changes around a joint can reveal in most instances the underlying mechanism of trauma. This may be helpful to analyze which joint supporting structures may be at risk. In the acute setting, plain radiography and CT scan may have an additional role in the detection of small avulsion fractures occurring at the site of minor areas of bone marrow edema. The clinical significance and natural history of bone marrow edema is still a matter of debate

    This paper will discuss the value of medical imaging in the detection and follow-up of bone marrow edema (BME), resulting from acute and chronic trauma in sports. MR imaging is the only imaging technique that allows direct evaluation of bone marrow edema in sports medicine. The use of fat suppressed T2-weighted or STIR images is particularly appropriate to detect bone marrow edema. The extent of bone marrow edema reflects the biomechanics of trauma. Compressive forces between two bony structures will result in extensive areas of bone marrow edema, whereas distraction forces provoke more subtle areas of bone marrow edema at the insertion of supporting structures of joints. In most clinical situations, a combination of compression and distraction forces is present, causing a complex pattern of bone marrow edema. A meticulous pattern approach of the distribution of these bone marrow changes around a joint can reveal in most instances the underlying mechanism of trauma. This may be helpful to analyze which joint supporting structures may be at risk. In the acute setting, plain radiography and CT scan may have an additional role in the detection of small avulsion fractures occurring at the site of minor areas of bone marrow edema. The clinical significance and natural history of bone marrow edema is still a matter of debate.

    Pathological conditions in the central nervous system, including stroke and trauma, are often exacerbated by cerebral edema. We recently identified a nonselective cation channel, the NCCa-ATP channel, in ischemic astrocytes that is regulated by sulfonylurea receptor 1 (SUR1), is opened by depletion of ATP and, when opened, causes cytotoxic edema. Here, we evaluated involvement of this channel in rodent models of stroke. SUR1 protein and mRNA were newly expressed in ischemic neurons, astrocyte...

    Full Text Available Brain edema is a potentially fatal pathological state that occurs after brain injuries such as stroke and head trauma. In the edematous brain, excess accumulation of extracellular fluid results in elevation of intracranial pressure, leading to impaired nerve function. Despite the seriousness of brain edema, only symptomatic treatments to remove edema fluid are currently available. Thus, the development of novel anti-edema drugs is required. The pathogenesis of brain edema is classified as vasogenic or cytotoxic edema. Vasogenic edema is defined as extracellular accumulation of fluid resulting from disruption of the blood-brain barrier (BBB and extravasations of serum proteins, while cytotoxic edema is characterized by cell swelling caused by intracellular accumulation of fluid. Various experimental animal models are often used to investigate mechanisms underlying brain edema. Many soluble factors and functional molecules have been confirmed to induce BBB disruption or cell swelling and drugs targeted to these factors are expected to have anti-edema effects. In this review, we discuss the mechanisms and involvement of factors that induce brain edema formation, and the possibility of anti-edema drugs targeting them.

The primary aim of therapy is to prevent and treat life-threatening cardiac and muscular complications. However, in the presence of severe symptomatic hypokalemia and gastrointestinal problems such as ileus, the intravenous route may be used in cases where serum K+ level is usually below 2.6 mEq/L. K+ given in intravenous fluids should not exceed 40 mEq/L. In case of emergency, 0.3–1 mEq/kg of K+ may be given intravenously over 1 hour. When higher concentrations (60–80 mEq/L are needed, infusion through a central vein under electrocardiography monitoring may be used.Keywords: neonatal, hypokalemia, newborn

    Paediatric and particularly neonatal neurosonography still remains a mainstay of imaging the neonatal brain. It can be performed at the bedside without any need for sedation or specific monitoring. There are a number of neurologic conditions that significantly influence morbidity and mortality in neonates and infants related to the brain and the spinal cord; most of them can be addressed by ultrasonography (US). However, with the introduction of first CT and then MRI, neonatal neurosonography is increasingly considered just a basic first line technique that offers only orienting information and does not deliver much relevant information. This is partially caused by inferior US performance – either by restricted availability of modern equipment or by lack of specialized expertise in performing and reading neurosonographic scans. This essay tries to highlight the value and potential of US in the neonatal brain and briefly touching also on the spinal cord imaging. The common pathologies and their US appearance as well as typical indication and applications of neurosonography are listed. The review aims at encouraging paediatric radiologists to reorient there imaging algorithms and skills towards the potential of modern neurosonography, particularly in the view of efficacy, considering growing economic pressure, and the low invasiveness as well as the good availability of US that can easily be repeated any time at the bedside.

  20. Emma Kohman and the early history of nutritional edema.

    Nutritional edema is a generalized edematous condition that afflicted whole populations of central European countries during World War 1--and other areas since that time--with a mortality rate of about 50%. An analogous condition in white rats was produced by Emma Kohman as a graduate student in Chicago (1916 to 1919). She fed the rats a diet similar to that consumed by human subjects but prevented or cured nutritional edema in the animals by feeding them good quality protein in suitable amounts. Her work, verified by others, was of immense practical significance and helped establish the value of animal experiments in the study of human diseases. Ms. Kohman gave up a scientific career to be a homemaker when she married in 1919.

  1. Immersion Pulmonary Edema in Female Triathletes

    2011-01-01

    Full Text Available Pulmonary edema has been reported in SCUBA divers, apnea divers, and long-distance swimmers however, no instances of pulmonary edema in triathletes exist in the scientific literature. Pulmonary edema may cause seizures and loss of consciousness which in a water environment may become life threatening. This paper describes pulmonary edema in three female triathletes. Signs and symptoms including cough, fatigue, dyspnea, haemoptysis, and rales may occur within minutes of immersion. Contributing factors include hemodynamic changes due to water immersion, cold exposure, and exertion which elevate cardiac output, causing pulmonary capillary stress failure, resulting in extravasation of fluid into the airspace of the lung. Previous history is a major risk factor. Treatment involves immediate removal from immersion and in more serious cases, hospitalization, and oxygen administration. Immersion pulmonary edema is a critical environmental illness of which triathletes, race organizers, and medical staff, should be made aware.

  2. Neurogenic pulmonary edema due to ventriculo-atrial shunt dysfunction: a case report

    2016-04-01

    Full Text Available ABSTRACT BACKGROUND AND OBJECTIVES: Pulmonary edema is caused by the accumulation of fluid within the air spaces and the interstitium of the lung. Neurogenic pulmonary edema is a clinical syndrome characterized by the acute onset of pulmonary edema following a significant central nervous system insult. It may be a less-recognized consequence of raised intracranial pressure due to obstructive hydrocephalus by blocked ventricular shunts. It usually appears within minutes to hours after the injury and has a high mortality rate if not recognized and treated appropriately. CASE REPORT: We report a patient with acute obstructive hydrocephalus due to ventriculo-atrial shunt dysfunction, proposed to urgent surgery for placement of external ventricular drainage, who presented with neurogenic pulmonary edema preoperatively. She was anesthetized and supportive treatment was instituted. At the end of the procedure the patient showed no clinical signs of respiratory distress, as prompt reduction in intracranial pressure facilitated the regression of the pulmonary edema. CONCLUSIONS: This report addresses the importance of recognition of neurogenic pulmonary edema as a possible perioperative complication resulting from an increase in intracranial pressure. If not recognized and treated appropriately, neurogenic pulmonary edema can lead to acute cardiopulmonary failure with global hypoperfusion and hypoxia. Therefore, awareness of and knowledge about the occurrence, clinical presentation and treatment are essential.

    Brain edema leading to an expansion of brain volume has a crucial impact on morbidity and mortal-ity following traumatic brain injury as it increases intracra-nial pressure, impairs cerebral perfusion and oxygenation,and contributes to additional ischemic injuries.Classically,two major types of traumatic brain edema exist: "vasogenic"and "cytotoxic/cellular".However, the cellular and molecu-lar mechanisms contributing to the development/resolution of traumatic brain edema are poorly understood and no ef-fective drugs can be used now.Aquaporin-4 (AQP4) is a water-channel protein expressed strongly in the brain, pre-dominantly in astrocyte foot processes at the borders be-tween the brain parenchyma and major fluid compartments, including cerebrospinal fluid and blood.This distribution suggests that AQP4 controls water fluxes into and out of the brain parenchyma.In cytotoxic edema, AQP4 deletion slows the rate of water entry into brain, whereas in vasogenic edema, AQP4 deletion reduces the rate of water outflow from brain parenchyma.AQP4 has been proposed as a novel drug target in brain edema.These findings sug-gest that modulation of AQP4 expression or function may be beneficial in traumatic brain edema.

    Objective To review the update research progress about the treatment of diabetic macular edema and to give helpful guidelines in the treatment of diabetic macular edema based on available evidence to date.Data sources A literature search of all English articles was performed on the online electronic PubMed database dated 1984 to 2009. The keywords searched included: macular edema, therapy, laser coagulation, intravitreal triamcinolone acetonide, vascular endothelial growth factor inhibitor, protein kinase C inhibitor and Pars plana vitrectomy. After finding relevant articles within these search limits, a manual search was conducted through the references from these articles.Study selection Original articles and critical reviews were reviewed and selected to address the stated purpose.Results To date, demonstrated means to reduce the risk of vision loss from diabetic macular edema include focal/grid laser photocoagulation and improved metabolic control. Emerging pharmacologic therapies (intravitreal triamcinolone acetonide, vascular endothelial growth factor inhibitors and protein kinase C beta-isoform inhibitors) and Pars plana vitrectomy have shown early promise in the treatment of diabetic macular edema.Conclusions As there has been extensive development in multiple treatments of diabetic macular edema, choice of the most suitable treatment for specific patients becomes important. Combination therapy of laser, pharmacological and surgical treatment modalities may offer an alternative to treatment of diabetic macular edema.

    Cystoid macular edema in its various forms can be considered one of the leading causes of central vision loss in the developed world. It occurs in a wide variety of pathologic conditions and represents the final common pathway of several basic processes. Therapeutic approaches to cystoid macular edema depend on a clear understanding of its contributing pathophysiologic mechanisms. This review will discuss the mechanism of ocular inflammation in cystoid macular edema with a particular focus on the inflammatory causes: post-operative, uveitic, and after laser procedures. A variety of pharmacologic agents targeting inflammatory molecules have been shown to reduce macular edema and improve visual function. However, the long-term efficacy and safety of most new therapies have yet to be established in controlled clinical trials.

    Full Text Available Scorpionism is a public health problem in some places in Mexico. The clinical symptoms of envenomation by scorpion sting are by sympathetic and parasympathetic stimulation, developing systemic and local symptoms. The Central Nervous System (CNS is one of the organs that are affected. In some cases, cerebral edema develops. In this report we present two pediatric cases with the association of envenomation by scorpion sting and cerebral edema. The first case developed severe cerebral edema, which progressed to a fatal outcome; and the other case developed mild cerebral edema with a satisfactory evolution. The pathophysiology of this complication is not well known and probably is the consequence of hypoxia, secondary to respiratory failure, laryngospasm and seizures that are manifestations of envenomation by scorpion sting.

    @@ Neurogenic pulmonary edema (NPE) is a type of pulmonary edema that occurs secondary to central nervous sytem (CNS) damage, namely centrogenic pulmonary edema or cerebrogenic pulmonary edema[1,2] NPE is clinically characterized by acute dyspnea and progressive hypoxemia, while tachycardia, hypertension and tachypnea are only nonspecific symptoms in early phase. Early diagnosis of NPE is difficult since chest X-ray shows no remarkable sign or only increased hazy lung markings in early stage[3]. Diagnosis can be made definitely in the late stage of NPE according to the following manifestation : paleness, clamminess, feeling of impending death, rales, frothy pink sputum, hypoxemia and bilateral widespread infiltration on chest roentgenography. However, successful rescue rate is very low and mortality rate could reach as high as 90% at this stage[4-6].

    The objective of this study was to assess reduction in cerebral edema following linear accelerator radiosurgery (LINAC) as first line therapy for brain metastasis. We reviewed the medical records of all patients who underwent LINAC radiosurgery for brain metastasis at our institution during 2010-2012, and who had not previously undergone either surgery or whole brain radiotherapy. Data were analyzed for 55 brain metastases from 46 patients (24 males), mean age 59.9 years. During the 2 months following LINAC radiosurgery, the mean steroid dose decreased from 4.8 to 2.6 mg/day, the mean metastasis volume decreased from 3.79±4.12 cc to 2.8±4.48 cc (p=0.001), and the mean edema volume decreased from 16.91±30.15 cc to 12.85±24.47 cc (p=0.23). The 17 patients with reductions of more than 50% in brain edema volume had single metastases. Edema volume in the nine patients with two brain metastases remained stable in five patients (volume change 10%, 2-14 cc). In a subanalysis of eight metastases with baseline edema volume greater than 40 cc, edema volume decreased from 77.27±37.21 cc to 24.84±35.6 cc (p=0.034). Reductions in brain edema were greater in metastases for which non-small-cell lung carcinoma and breast cancers were the primary diseases. Overall, symptoms improved in most patients. No patients who were without symptoms or who had no signs of increased intracranial pressure at baseline developed signs of intracranial pressure following LINAC radiosurgery. In this series, LINAC stereotactic radiosurgery for metastatic brain lesions resulted in early reduction in brain edema volume in single metastasis patients and those with large edema volumes, and reduced the need for steroids.

    2007-01-01

    OBJECTIVE: To investigate the relationship of aquaporin 4 (AQP4) and brain edema.DATA SOURCES: Using the terms of "aquaporin-4, brain edema", we searched PubMed database to identify studies published from January 1997 to April 2006 in the English languages. Meanwhile, we also searched China National Knowledge Infrastructure (CNKI) for related studies.STUDY SELECTION: The collected data were selected firstly. Studies on AQP4 and brain edema were chosen and their full-texts were searched for, and those with repetitive or review studies were excluded.DATA EXTRACTION: Totally 146 related studies were collected, 42 of them were involved and the other 104 studies were used for reading reference data.DATA SYNTHESIS: AQP4 is a selective water permeable integral membrane protein. It is mainly expressed in astrocytes and ependymocyte, and is the important structural basis for water regulation and transportation between glial cells and cerebrospinal fluid or vessels. Phosphorylation is involved in the regulation of AQP4.AQP4 participates in the formation of brain edema caused by various factors. Studies on the structure and pathological changes of AQP4 are still in the initial stage, and the role and mechanism of AQP4 in the formation of brain edema is very unclear.CONCLUSION: AQP4 plays a critical regulating role in the formation of ischemic brain edema, but whether it is regulated by drugs lacks reliable evidence.

  1. Neonatal circumcision.

    Science.gov (United States)

    Lerman, S E; Liao, J C

    2001-12-01

    The merits of neonatal circumcision continue to be debated hotly. Some argue that circumcision is a "uniquely American medical enigma." Most of the world's male population remains uncircumcised; however, most boys born in the United States continue to undergo neonatal circumcision. Review of existing literature supports that most children who are uncircumcised do well from a medical standpoint and, thus, the question of whether US health care practitioners are subjecting neonates to an unnecessary surgical procedure remains. The medical benefits of circumcision are multiple, but most are small. The clearest medical benefit of circumcision is the relative reduction in the risk for a UTI, especially in early infancy. Although this risk [figure: see text] is real, the absolute numbers are small (risk ranges from 1 in 100 to 1 in 1000), and one investigator has estimated that it may take approximately 80 neonatal circumcisions to prevent one UTI. In the case of a patient with known urologic abnormalities that predispose to UTI, neonatal circumcision has a clearer role in terms of medical benefit to the patient. Most of the other medical benefits of circumcision probably can be realized without circumcision as long as access to clean water and proper penile hygiene are achieved. Proper penile hygiene should all but eliminate the risk for foreskin-related medical problems that will require circumcision. Moreover, proper hygiene and access to clean water has been shown to reduce the rate of development of squamous cell carcinoma of the penis in the uncircumcised population. Proper techniques on the care of the foreskin are illustrated in the American Academy of Pediatrics pamphlet titled "How to care for the uncircumcised penis." Regarding the relationship between STDs and circumcision, patient education and the practice of low-risk sexual behavior make a far greater impact than does routine circumcision in hopes of reducing the spread of HIV and other STDs.

    (1) To explore attitudes and beliefs of neonatal nurses toward nursing care for dying neonates; (2) to estimate the influence of neonatal nurses' personal and professional characteristics on their attitudes towards end-of life care for dying infants. A cross-sectional design was used. A questionnaire was used to collect data from 80 neonatal nurses. Research setting was four level III NICUs at four medical centers around the central region of Taiwan. Research participants were neonatal nurses who had worked for at least 1 year in one of level III NICUs and had been directly involved with the care of dying infants. Research participants were 80 neonatal nurses (response rate 100 %). Research findings identified eight barriers hindering neonatal palliative care practice. These barriers were insufficient communication due to the lack of an in-service educational program; the lack of available counseling help for neonatal clinicians; inability to express personal opinions, values and beliefs towards neonatal palliative care; insufficient staffing; the lack of unit policies/guidelines for supporting palliative care; the technological imperative; parental demands and personal beliefs about death and previous experience caring for dying infants. Further studies are needed to explore each barrier and to provide in-service neonatal palliative care educational programs that are needed to decrease these barriers.

    Full Text Available Diabetic macular edema (DME is the main cause of visual impairment in diabetic patients. Macular edema within 1 disk diameter of the fovea is present in 9% of the diabetic population. The management of DME is complex and often multiple treatment approaches are needed. This review demonstrates the benefits of intravitreal triamcinolone, bevacizumab and ranibizumab as adjunctive therapy to macular laser treatment in DME. The published results indicate that intravitreal injections of these agents may have a beneficial effect on macular thickness and visual acuity, independent of the type of macular edema that is present. Therefore, pharmacotherapy could complement focal/grid laser photocoagulation in the management of DME. For this review, we performed a literature search and summarized recent findings regarding combined therapy for DME.

    Full Text Available Background: Neonatal pain management has received increasing attention over the past four decades. Research into the effects of neonatal pain emphasises the professional, ethical and moral obligations of staff to manage pain for positive patient outcomes. However, evaluation studies continuously report evidence of inadequate neonate pain management and a gap between theory and practice.Objective: This study reviewed current practice in neonatal pain management to describe the knowledge, attitudes and practices of nurses and doctors regarding pain management for neonates in two academic hospitals.Method: A non-experimental, prospective quantitative survey, the modified Infant Pain Questionnaire, was used to collect data from 150 nurses and doctors working in the neonatal wards of two academic hospitals in central Gauteng.Results: The response rate was 35.33% (n = 53, most respondents being professional nurses (88.68%; n = 47 working in neonatal intensive care units (80.77%; n = 42; 24 (45.28% had less than 5 years’ and 29 respondents 6 or more years’ working experience in neonatal care. A review of pain management in the study setting indicated a preference for pharmacological interventions to relieve moderate to severe pain. An association (p < 0.05 was found between pain ratings on 5 procedures and frequency of administration of pharmacological pain management. Two-thirds of respondents (64% reported that there were no pain management guidelines in the neonatal wards in which they worked.Conclusion: The interventions to manage moderate neonatal pain are in line with international guidelines. However, neonatal pain management may not occur systematically based on prior assessment of neonatal pain, choice of most appropriate intervention and evaluation. This study recommends implementation of a guideline to standardise practice and ensure consistent and adequate pain management in neonates

    Hypotonia is a common occurrence in pediatrics, especially in the neonatal period. The hypotonic neonate represents a diagnostic challenge for the general pediatrician because hypotonia may be caused by a lesion at any level in the neuraxis: (1) central nervous system (CNS), (2) peripheral nerves (PN), (3) neuromuscular junction, or (4) muscles. Distinguishing among these pathologies is a particularly arduous task. This review will discuss the clinical approach to neonatal hypotonia with emphasis on disorders of the peripheral nervous system and muscle, and the importance of the electrophysiological study as a diagnostic test.

    An otherwise healthy 5-week-old infant with erythematous plaques predominantly on the face and scalp presented to our dermatology clinic. The mother had been diagnosed with lupus erythematosus 2 years earlier but her disease was quiescent. Neonatal lupus is a rare condition associated with transplacental transfer of IgG anti-SSA/Ro and anti-SSB/La antibodies from the mother to the fetus. Active connective tissue disease in the mother does not have to be present and in fact is often absent. Although the cutaneous, hematologic and hepatic manifestations are transient, the potential for permanent heart block makes it necessary for this to be carefully ruled out. As in this case, the dermatologist may be the one to make the diagnosis and should be aware of the clinical presentation, work-up, and management of this important disease.

    2013-01-01

    Full Text Available The main objective of the facial edema evaluation is providing the needed information to determine the effectiveness of the anti-inflammatory drugs in development. This paper presents a system that measures the four main variables present in facial edemas: trismus, blush (coloration, temperature, and inflammation. Measurements are obtained by using image processing and the combination of different devices such as a projector, a PC, a digital camera, a thermographic camera, and a cephalostat. Data analysis and processing are performed using MATLAB. Facial inflammation is measured by comparing three-dimensional reconstructions of inflammatory variations using the fringe projection technique. Trismus is measured by converting pixels to centimeters in a digitally obtained image of an open mouth. Blushing changes are measured by obtaining and comparing the RGB histograms from facial edema images at different times. Finally, temperature changes are measured using a thermographic camera. Some tests using controlled measurements of every variable are presented in this paper. The results allow evaluating the measurement system before its use in a real test, using the pain model approved by the US Food and Drug Administration (FDA, which consists in extracting the third molar to generate the facial edema.

    MR imaging criteria for diagnosing acute disseminated encephalomyelitis (ADEM) have not been clearly established. Due to the wide spectrum of differential considerations, new imaging features allowing early and accurate diagnosis for ADEM are needed. We hypothesized that ADEM lesions would be characterized by vasogenic edema due to the potential reversibility of the disease. Sixteen patients who met the diagnostic criteria for ADEM proposed by the International Pediatric Multiple Sclerosis Study Group (IPMSSG) and had complete MR imaging studies performed at our institution during the acute phase of the disease were identified retrospectively and evaluated by experienced pediatric neuroradiologists. Vasogenic edema was demonstrated on diffusion-weighted imaging (DWI) and corresponding apparent diffusion coefficient (ADC) maps in 12 out of 16 patients; cytotoxic edema was identified in two patients while the other two patients displayed no changes on DWI/ADC. ADC values for lesions and normal-appearing brain tissue were 1.39 ± 0.45 x 10{sup -3} and 0.81 ± 0.09 x 10{sup -3} mm/s{sup 2}, respectively (p = 0.002). When considering a cutoff of 5 days between acute and subacute disease, no difference between ADC values in acute vs. subacute phase was depicted. However, we found a significant correlation and an inverse and significant relationship between time and ADC value. We propose that vasogenic edema is a reliable diagnostic sign of acute neuroinflammation in ADEM. (orig.)

    Diabetes is a serious chronic condition,which increase the risk of cardiovascular diseases,kidney failure and nerve damage leading to amputation.Furthermore the ocular complications include diabetic macular edema,is the leading cause of blindness among adults in the industrialized countries.Today,blindness from diabetic macular edema is largely preventable with timely detection and appropriate interventional therapy.The treatment should include an optimized control of glycemia,arterial tension,lipids and renal status.The photocoagulation laser is currently restricted to focal macular edema in some countries,but due the high cost of intravitreal drugs,the use of laser treatment for focal and diffuse diabetic macular edema(DME),can be valid as gold standard in many countries.The intravitreal anti vascular endothelial growth factor drugs(ranibizumab and bevacizumab),are indicated in the treatment of all types of DME,but the correct protocol for administration should be defined for the different Retina Scientific Societies.The corticosteroids for diffuse DME,has a place in pseudophakic patients,but its complications restricted the use of these drugs for some patients.Finally the intravitreal interface plays an important role and its exploration is mandatory in all DME patients.

    Natal teeth have been defined as teeth which are present at birth, while neonatal teeth erupt during the first 30 days. Their occurrence is rare, the prevalence ranges from 1:2000 to 1:3000 with a higher frequency in the lip and palate clefts and syndroms. In about 85% natal or neonatal teeth are lower central incisors (60% in pairs), rare are upper teeth, molars and multiple teeth. In almost 90% they are part of the deciduous dentition. A lot of possible causes of early eruption are discussed, but only the relation to hereditary factors seems to be evident. An autosomal dominant trait is often described. The appearance of these teeth is dependent on the degree of maturity, but most of the time it is loose, small, discoloured and hypoplastic. Histologically, enamel hypoplasia with normal prism structure is apparent. No significant disturbances of the dentin structures are observed, only cervically dentin becomes atubular with spaces and enclosed cells. A large vascular pulp and failure of root formation are further investigations. Our microhardness measurements showed values from 24.3-32.4 KHN for enamel and 48.3-62.2 KHN for dentin, while normal deciduous teeth have an enamel hardness of 322.0 +/- 17.5 KHN. The thickness of enamel was never more than 280 microm compared to up to 1200 microm in normal teeth. This shows the retarded development of natal and neonatal teeth, because mineralization has not finished at the time of birth. In accordance with developmental age tooth structure and appearence are normal. In consideration of complications as Riga-Fede-disease, feeding problems, possibility of infection and hypermobility most of the time extraction is the treatment of choice, but in the interest of protecting the child this decision should be made carefully.

    Background Intravitreal injection of triamcinolone acetonide (TA) can effectively eliminate central vein occlusion macular edema and improve visual acuity, and photopic negative response (PhNR) can reflect the inner retinal function of RGCs and their axons. It is possible there is a correlation between these two observations.Objective This study was to evaluate the changes of PhNR of flash electroretinogram (F-ERG) after intravitreal injection of TA for macular edema in central retinal vein occlusion ( CRVO ). Methods Thirteen eyes of 12 patients with macular edema caused by CRVO received an injection of 0. 1 ml (4 rg) of TA. PhNR,visual acuity and retinal thickness of macular area were assessed with Roland RETI scan 3. 15 system,decimal visual chart and Stratus optical coherence tomography (OCT) before and 4 weeks after the administration of TA. Written informed consent was obtained from each subject before any medical procedure. Results Visual acuity was improved in 12 eyes and stable in 1 eye 4 weeks following the intravitreal injection of TA. OCT showed that the retinal thickness of the macular area was reduced ;meanwhile,elevation of the amplitude of PhNR also was seen in the F-ERG after the administration of TA in comparison with before the administration of TA. The calculated results determined that the visual acuities were 0. 32t0. 12 and 0. 48±0. 09 (t=6. 325 ,P=0. 000) ,and the retinal thickness values of the macular area were (459.46± 131.31 ) μm and ( 297.54 ±43.31 ) μm ( t = 5.961, P = 0. 000 ), and the average amplitude of PhNR were ( 80. 23±22.96 ) μV and (61.28 ±20. 16 ) μV ( t = 4. 438, P = 0. 001 ) before and after the intravitreal injection of TA, respectively,showing significant differences. No significant correlation was found between PhNR amplitude and retinal thickness of the macular area both before and after the administration of TA ( before: r = 0. 587, P = 0. 035; after:r=-0. 011 ,P = 0. 971 ). Conclusion PhNR can be used for

    In order to clarify the mechanisms underlying cerebral contusion-induced CBF disturbance and edema formation, echoplanar diffusion and perfusion images were obtained in the patients with cerebral contusion. In the acute phase within 48 hours post-trauma, the apparent diffusion coefficient (ADC) showed various levels with a tendency to increase in the central area of contusion (ADC ratio=1.06{+-}0.21). In contrast, the ADC was significantly reduced in the peripheral area of contusion (ADC ratio=0.87{+-}0.16). The ADC at 2 weeks post-trauma increased both in the central (ADC ratio=1.16{+-}0.26) and the peripheral area of contusion (ADC ratio=1.10{+-}0.26, p<0.05), as compared to those within 48 hours post-trauma. The perfusion images showed a wide spread CBF depression extending beyond the area of contusion observed on the T1 and T2 weighted images. These results indicate that; in the early phase of contusion-induced edema formation, cytotoxic edema is predominant, especially in the peripheral area of contusion, and vasogenic edema appears thereafter. The CBF depression may contribute such cytotoxic edema formation in the surrounding area of cerebral contusion. It is concluded that echo-planar diffusion and perfusion images are excellent technique to investigate the evolution of CBF disturbance and edema formation following traumatic brain injury. (author)

    Objective To determine the correlation between central macular thickness (CMT) and the visual function in patients iwht macular edema (ME). Methods The clinical data of 42 eyes of 40 patients with ME which were examined by optical coherence tomography (OCT) and microperimetry (MP-1) wereretrospectively analyzed. In 40 patients (42 eyes), diabetic ME (DME) was in 27 eyes,branch retinal vein occlusion was in 11eyes, and central retinal vein occlusion was in 4 eyes. All of the eyes had undergone OCT,MP-1 and best-corrected visual acuity (BCVA) test. Central macular thickness (CMT) was measured by fast macular scans using OCT. Retinal sensitivity (MS) and fixation patterns were evaluated by Mp-1.The position was chosen :2 disc diameters (DD) temporal to the disc and one third of a DD inferior to the centre of the disc. Results The correlation between CMT and BCVA is not significant (r=-0. 429, P=0. 069) as well as the correlation between CMT and MS (r=-0. 433,P=0. 058). The difference of CMT between the unstable and stable group was significant (F = 3. 262, P = 0. 039). The difference of CMT between the central fixation group and preferred retinal locus (PRL) group was significant (F=3. 173,P=0. 044). Conclusions BCVA and MS have no significant correlation with CMT. When CMT increases, the fixation stability decreases, fixation location, changes, and PRL occurs.%目的 观察黄斑水肿(ME)状态下黄斑中心凹厚度与视功能改变之间的相关性.方法 回顾分析应用光相干断层扫描(OCT)联合微视野计(MP-1)检测的ME患者40例42只眼的临床资料.所有患眼均行验光插片,记录最佳矫正视力(BCVA);采用德国Zeiss-HumphreyOCT仪进行OCT检查;意大利Nidek公司MP-1微视野计进行眼底成像、固视检测和视野检查.OCT及MP-1检查均以视盘颢侧2个视盘直径(DD)、下方1/3 DD作为黄斑中心凹进行检查.采用统计学方法对比分析患眼BCVA、中心凹厚度(CMT)、中心10°的光敏感度(MS

    Pseudophakic cystoid macular edema (PCME) is a common complication following cataract surgery. Acute PCME may resolve spontaneously, but some patients will develop chronic macular edema that affects vision and is difficult to treat. This disease was described more than 50 years ago, and there are multiple options for clinical management. We discuss mechanisms, clinical efficacy, and adverse effects of these treatment modalities. Topical non-steroidal anti-inflammatory agents and corticosteroids are widely used and, when combined, may have a synergistic effect. Intravitreal corticosteroids and anti-vascular endothelial growth factor (anti-VEGF) agents have shown promise when topical medications either fail or have had limited effects. Randomized clinical studies evaluating anti-VEGF agents are needed to fully evaluate benefits and risks. When PCME is either refractory to medical therapy or is associated with significant vitreous involvement, pars plana vitrectomy has been shown to improve outcomes, though it is associated with additional risks.

  11. Influenza leaves a TRAIL to pulmonary edema.

    Influenza infection can cause acute respiratory distress syndrome (ARDS), leading to poor disease outcome with high mortality. One of the driving features in the pathogenesis of ARDS is the accumulation of fluid in the alveoli, which causes severe pulmonary edema and impaired oxygen uptake. In this issue of the JCI, Peteranderl and colleagues define a paracrine communication between macrophages and type II alveolar epithelial cells during influenza infection where IFNα induces macrophage secretion of TRAIL that causes endocytosis of Na,K-ATPase by the alveolar epithelium. This reduction of Na,K-ATPase expression decreases alveolar fluid clearance, which in turn leads to pulmonary edema. Inhibition of the TRAIL signaling pathway has been shown to improve lung injury after influenza infection, and future studies will be needed to determine if blocking this pathway is a viable option in the treatment of ARDS.

    Full Text Available A 28-year-old healthy male complaining of vision loss in his right eye was discovered to have localized bi-nasal macular edema in the presence of a pituitary adenoma. The presence of a junctional scotoma composed by a central scotoma in the right eye associated with superior temporal quadrantanopia in the fellow eye was seen. The pattern detected in the visual field suggested the presence of an expansive mass at the level of the optic chiasm. Optical coherence tomography findings also revealed subtle macular thickness beyond normal in the superior and nasal quadrants of both maculae. This report illustrates the importance of suspecting a pituitary adenoma in the light of uncharacteristic retinal alterations.

A 37-year-old Caucasian man with Danon disease treated with topical and oral carbonic anhydrase inhibitors participated in the study. Examinations performed before and during treatment included visual acuity (VA, spectral-domain optical coherence tomography, and electroretinography. Following total 48 weeks of treatment, VA decreased from 20/30 OD, 20/200 OS, to 20/40 OD, CF OS. The mean central retinal thickness was unchanged from baseline 263 μm OD , 226 μm OS, after treatment 283 μm OD and 202 μm OS. In our case, carbonic anydrase inhibitors were not effective. However, a general recommendation cannot be given based on a single case.

    Full Text Available Objective: The objective of the following study is to detect genes encoding carbapenem resistance in Klebsiella pneumoniae sepsis outbreak in a neonatal intensive care unit (NICU. Materials and Methods: Antibiotic sensitivity test was performed by standard Kirby Bauer disc diffusion technique and minimum inhibitory concentrations of antibiotics was determined by VITEK-2. Polymerase chain reaction (PCR assays and sequencing was used to determine the presence of beta-lactamase encoding genes. Conjugation experiments were performed to determine the transferability of beta-lactamase. Isolate relatedness were determined by repetitive-element PCR (REP, enterobacterial repetitive intergenic consensus (ERIC PCR and random amplified polymorphic deoxyribonucleic acid (RAPD. Results: All the isolates were completely resistant to the second and third generation cephalosporins tested as well as carbapenems. Susceptibility profiling of the isolates indicated that 100% retained susceptibility to tigecycline and colistin. Conjugation experiments indicated that blaNDM-1 was transferable and likely through a plasmid-mediated event. All the isolates showed the presence of blaNDM-1 with co association of bla CTX-M-15 . REP-PCR, ERIC-PCR and RAPD revealed a single clonal type circulating in NICU environment. Conclusion: Co-production of NDM-1 with CTX-M-15 in K. pneumoniae isolates was detected for the first time in our NICU. Transmission of plasmid carrying these resistant genes to other members of Enterobacteriaceae will increase the incidence of multidrug resistance. Early detection of these genes will help in prevention and adequate infection control by limiting the spread of these organisms.

    Full Text Available El edema pulmonar postobstructivo (EPPO es una complicación postoperatoria cuyo manejo adecuado depende de un diagnóstico etiológico correcto. El EPPO se clasifica en dos tipos. El tipo I es secundario a la obstrucción aguda de la vía aérea superior. Por su parte, el tipo II ocurre luego de corregir quirúrgicamente una obstrucción crónica de la vía aérea. Fisiopatológicamente, el mecanismo que explica el cuadro es una disminución marcada de la presión intersticial en el nivel pericapilar pulmonar resultante de la inspiración forzada. Lo anterior produce fuga capilar y el consecuente edema de pulmón. El manejo de este cuadro requiere de soporte respiratorio que incluye ventilación mecánica e incluso presión positiva al final de la espiración (PEEP. El pronóstico es muy bueno si el diagnóstico es correcto y oportuno. Se reportan 3 casos que ilustran la entidad, su diagnóstico y manejo.Postobstructive pulmonary edema (POPPE is a postoperative complication and its approach depends on an appropriate diagnosis. POPPE can be classified in two types. POPPE type I is caused by acute upper airway obstruction , and type II is due to chronic obstruction. The mechanism of this entity is a marked decrease in pericapilar interstitical pressure in the lung that results in capillary leakage and edema. Its treatment requires mechanical ventilatory support including positive end expiratory pressure (PEEP. Its prognosis is very good if the diagnosis is done appropriately. We report three cases that illustrate its diagnosis and treatment.

Objectives: To assess the effectiveness of interventions in the treatment of uveitic macular edema. Search strategy: Cochrane Central Register of Controlled Trials, Medline, and Embase. There were no language or data restrictions in the search for trials. The databases were last searched on December 1, 2011. Reference lists of included trials were searched. Archives of Ophthalmology, Ophthalmology, Retina, the British Journal of Ophthalmology, and the New England Journal of Medicine were searched for clinical trials and reviews. Selection criteria: Participants of any age and sex with any type of uveitic macular edema were included. Early, chronic, refractory, or secondary uveitic macular edema were included. We included trials that compared any interventions of any dose and duration, including comparison with another treatment, sham treatment, or no treatment. Data collection and analysis: Best-corrected visual acuity and central macular thickness were the primary outcome measures. Secondary outcome data including adverse effects were collected. Conclusion: More results from randomized controlled trials with long follow-up periods are needed for interventions for uveitic macular edema to assist in determining the overall long-term benefit of different treatments. The only intervention with sufficiently robust randomized controlled trials for a meta-analysis was acetazolamide, which was shown to be ineffective in improving vision in eyes with uveitic

    Purpose:Corneal thickness assessment is a common clinical procedure applied in corneal and contact lens care. This study aims to investigate the effect of age on hypoxiainduced corneal swelling.Methods:Eighteen male subjects were equally divided into the younger [(23.7±0.8) and older [(74.4±2.5) years old]groups.Each subject wore a thick soft contact lens (uniform thickness of 0.3 mm) on the left cornea. With the contact lens in place, the baseline central corneal thickness was measured using a specially designed photo-pachometer. The lens was then patched behind the closed eyelids, producing an extremely hypoxic stress to the cornea. The change in central corneal thickness was monitored every 20 minutes with momentary disruptions to the hypoxic stress over the next 2 hours. The increase in thickness was taken as an index of corneal edema. The rate of change in corneal thickness, as derived from a non-linear mathematical model, was compared between groups. Results:The corneal thickness of both age groups increased significantly with time (P<0.000 1 ). The mean corneal swelling constant for the older subjects was 16.5 × 10-3 (S.E.M. = 2.65 × 10-3) and the value for the younger subjects was 46.5 × 10-3 (S.E.M. = 3.25× 10-3). The difference was statistically significant (P < 0.000 1 ).Conclusion:Aging cornea has a slower hypoxia-induced edema response compared with the younger group. Whether it is caused by a decreased corneal lactate production or an increased resistance to physical expansion deserves further investigation. Eye Science2004;20:1-5.

    The increasing number of successfully treated newborns with disturbances of the adaptive period can measure effectiveness of neonatal intensive care units (NICU). The authors summarized some health problems of the former NICU patients. Central nervous system (CNS) of the premature, especially low (LBW) and very low birth weight (VLBW) infant, is in serious danger of improper development. The lack of neurological disturbances in early infancy does not exclude further pathological events and such patients require long-term observation and follow-up. High-risk newborns are of great need of precise imaging and diagnosis of CNS, which should be performed before discharge. Early stimulation and developmental care program are the crucial points in the management of newborns with neurological abnormalities. Sensorial problems, especially the rate of vision and hearing impairments, can be significantly reduced when prophylactic schedule is applied. Both, etiological factors leading to respiratory insufficiency and some iatrogenic effects of the therapy, can influence respiratory system. Symptoms of different intensity--from sneezing caused by nasal mucous membrane edema to the severe forms of bronchopulmonary dysplasia (BPD)--may last for a long time and influence the child's general condition. The surgical closure of Botall's duct (persistent ductus arteriosus--PDA) usually normalizes the circulatory system. In serious heart defects or isolated shunt-type defects, the compensation of the circulatory system can easily be disturbed. Digestive tract problems belong to the two main groups: first--connected with the prematurity and immature interstitial functioning (necrotizing enterocolitis, digestive and absorption abnormalities, hepatic cholestasis), and second--caused by congenital defects requiring immediate surgical intervention. Despite different types of the diseases, the treatment and care have to be focused on necessary for the growing organism, optimal nutrients and

  20. MR imaging of the neonatal brain: Pathologic features

    International Nuclear Information System (INIS)

    Seventy-three neonates, aged 29-43 weeks since conception, were studied. US and/or CT correlations were obtained in most infants with pathology. In the first 4-5 days after hemorrhage, US and CT were superior to MR imaging, but after that time MR imaging was the single best modality for imaging blood. In early premature infants with very watery white matter, US detected infarction and brain edema that were poorly seen on both MR imaging and CT. However, in late premature and full-term infants, MR imaging was better than CT in distinguishing between normal white matter and infarction. Only MR imaging disclosed delayed myelination in 13 term infants with hydrocephalus and severe asphyxia. MR imaging with play an important role in imaging neonates once MR imaging-compatible monitors and neonatal head coils become widely available

    Background The dialysis disequilibrium syndrome is characterized by neurologic deterioration and cerebral edema which occurs after hemodialysis. The purpose of this study was to investigate the pathogenesis of acute cerebral and pulmonary edema induced by hemodialysis.Methods We evaluated the effects of hemodialysis on the biochemical and hemodynamic parameters of the plasma and cerebrospinal fluid, including the intracranial pressure, dry/wet ratio, and pulmonary edema index, and we also examined the pathological changes of the brain and lung tissue in dogs suffering from uremia.Results Seventy-two hours after bilateral ureteral ligation, 10 uremic dogs were hemodialyzed for 2 hours, yielding a 73.6% and 60.1% decrease in the plasma urea and creatinine, respectively, a decrease in the plasma osmolality from (359±18) mOsm/kgH2O to (304±6) mOsm/kgH2O (P <0.01 ), a decrease in the dry/wet ratio of the lung and brain tissue,and an increase in the hemodynamic parameters (right atrial pressure, right ventricular pressure, pulmonary artery pressure, pulmonary capillary wedge pressure, and central venous pressure), intracranial pressure, total pulmonary resistance index, and pulmonary edema index. Moreover, the pathological examination revealed lung and brain edema in the dialyzed dogs. This group was compared to 3 control groups: 6 uremic dogs which were sham dialyzed without dialysate so that no fall in the plasma urea occurred, and 12 uremic and 12 nonuremic animals that were not dialyzed.However, the parameters mentioned above were not significantly changed among these 3 control groups.Conclusions The acute brain and lung edema in our model appeared to be primarily due to a large osmotic gradient between the plasma and the brain and lung. This is the "urea reverse effect" which promoted the osmotically-induced lung and brain swelling.

    Acute hemorrhagic edema of infancy (AHEI) is a cutaneous vasculitis seen in children. Many consider it to be a clinical variant of Schönlein-Henoch purpura, but others regard it as a separate entity because of its benign nature, age of onset, lack of visceral involvement, and frequent absence...... of vascular immunoglobulin A deposition. It is clinically characterized by large "cockade" or rosette-shaped, annular, purpuric lesions involving the face and extremities; erythematous edema; and mild fever.

    Full Text Available Purpose. To evaluate the effects of pars plana vitrectomy (PPV on recurrent macular edema due to branch retinal vein occlusion (BRVO after intravitreal injections of bevacizumab (IVB. Methods. This retrospective study included 22 eyes of 22 patients who underwent single or multiple IVB injections for macular edema due to BRVO and showed a recurrence of macular edema. All patients then underwent PPV and were followed up for more than 6 months after the surgery with examinations of best corrected visual acuity (BCVA and optical coherence tomography (OCT. OCT parameters were central macular thickness (CMT and average retinal thickness in a 1-mm-diameter circular region at the fovea (MRT. Results. Mean BCVA, CRT, and MRT were significantly improved from the baseline after PPV. Greater improvement of BCVA, CRT, and MRT was obtained after 1 month of IVB than after 6 months of PPV. No eyes showed worsening of macular edema after the surgery. Conclusion. PPV improved BCVA and recurrent macular edema due to BRVO, but PPV that was less effective than IVB had been in the same patients. PPV may be one of the treatment options for recurrent macular edema due to BRVO after IVB.

    Full Text Available Abstract Background Neonatal mortality accounts for almost 40 per cent of under-five child mortality, globally. An understanding of the factors related to neonatal mortality is important to guide the development of focused and evidence-based health interventions to prevent neonatal deaths. This study aimed to identify the determinants of neonatal mortality in Indonesia, for a nationally representative sample of births from 1997 to 2002. Methods The data source for the analysis was the 2002–2003 Indonesia Demographic and Health Survey from which survival information of 15,952 singleton live-born infants born between 1997 and 2002 was examined. Multilevel logistic regression using a hierarchical approach was performed to analyze the factors associated with neonatal deaths, using community, socio-economic status and proximate determinants. Results At the community level, the odds of neonatal death was significantly higher for infants from East Java (OR = 5.01, p = 0.00, and for North, Central and Southeast Sulawesi and Gorontalo combined (OR = 3.17, p = 0.03 compared to the lowest neonatal mortality regions of Bali, South Sulawesi and Jambi provinces. A progressive reduction in the odds was found as the percentage of deliveries assisted by trained delivery attendants in the cluster increased. The odds of neonatal death were higher for infants born to both mother and father who were employed (OR = 1.84, p = 0.00 and for infants born to father who were unemployed (OR = 2.99, p = 0.02. The odds were also higher for higher rank infants with a short birth interval (OR = 2.82, p = 0.00, male infants (OR = 1.49, p = 0.01, smaller than average-sized infants (OR = 2.80, p = 0.00, and infant's whose mother had a history of delivery complications (OR = 1.81, p = 0.00. Infants receiving any postnatal care were significantly protected from neonatal death (OR = 0.63, p = 0.03. Conclusion Public health interventions directed at reducing neonatal death should

    In this study of branch retinal vein occlusion, we distinguished between cystoid macular edema caused by increased capillary pressure and noncystoid edema due to hard exudates in the macula caused by chronic leakage from vascular abnormalities in the posterior pole or midperiphery. We performed laser photocoagulation in 51 eyes with cystoid macular edema to achieve focal narrowing of the retinal arterioles perfusing the macular area affected by the cystoid edema; good anatomic and functional results were achieved in 40 of these eyes (78%). In 25 of the five eyes, the treated segment of the retinal arteriole was outside the area of macular edema; results were successful in 19 of these eyes (76%). In 14 eyes with noncystoid exudative macular edema, we performed laser photocoagulation to the vascular abnormalities; good anatomic and functional results were obtained in 12 of these (86%).

  9. Effects of dexamethasone on brain edema

    International Nuclear Information System (INIS)

    Experimental cerebral edema was produced on the right parietal lobe of Wistar male rats with a cold metal probe cooled by liquid nitrogen. Twenty hour later, 3H-dexamethasone was either intramuscularly or intravenously injected into rats, estimated in the brain tissue by the liquid scintillation counting method. Edematous brain generally contained much higher 3H-activity than the control. Furthermore, I.V. injection showed higher 3H-activity than I.M injection in edematous and control brains at all times. For examination of the subcellular distribution of 3H-dexamethasone in edematous brain, 3H-activity was most strongly detected in the supernatant fraction (63%), followed by the heavy mitochondrial fraction (25.4%) and the nuclear fraction (8.4%). Although edematous brain tissue constantly demonstrated higher 3H-activity than the control, its supernatant fraction conversely had less activity. As a next step, distribution of 3H-dexamethasone in the supernatant fraction was studies. The result was that the high molecular weight fraction in the edematous brain showed higher radioactivity than the control. From these findings, unequivocal distribution of dexamethasone in the supernatant fraction of edematous brain tissue could be correlated with its biochemical action for preventing brain edema.

    Thioperamide, a selective histamine H3 receptor antagonist, can increase histamine content in the brain, improve brain edema, and exert a neuroprotective effect. This study aimed to examine the mechanism of action of thioperamide during brain edema in a rat model of neonatal hypoxic- is-chemic encephalopathy. Our results showed that thioperamide significantly decreased brain water content and malondialdehyde levels, while significantly increased histamine levels and superoxide dismutase activity in the hippocampus. This evidence demonstrates that thioperamide could pre-vent oxidative damage and attenuate brain edema fol owing neonatal hypoxic-ischemic encepha-lopathy. We further observed that changes in the above indexes occurred after combined treatment of thioperamide with the H1 receptor antagonist, pyrilamine, and the H2 receptor antagonist, ci-metidine. Experimental findings indicated that pyrilamine reversed the effects of thioperamide;however, cimetidine had no significant influence on the effects of thioperamide. Our present findings suggest that thioperamide can increase brain histamine content and attenuate brain edema and oxidative damage by acting in combination with postsynaptic H1 receptors in a rat model of neo-natal hypoxic-ischemic encephalopathy.

    Globoid cell leukodystrophy (GLD) or Krabbe disease is an autosomal recessive disorder resulting from the defective lysosomal enzyme galactocerebrosidase (GALC). The lack of GALC enzyme leads to severe neurological symptoms. While most human patients are infants who do not survive beyond 2 years of age, older patients are also diagnosed. In addition to human patients, several naturally occurring animal models, including dog, mouse, and monkey, have also been identified. The mouse model of Krabbe disease, twitcher (twi) mouse has been used for many treatment trials including gene therapy. Using the combination of intracerebroventricular, intracerebellar, and intravenous (iv) injection of the adeno-associated virus serotype rh10 (AAVrh10) expressing mouse GALC in neonate twi mice we previously have demonstrated a significantly extended normal life and exhibition of normal behavior in treated mice. In spite of the prolonged healthy life of these treated mice and improved myelination, it is unlikely that using multiple injection sites for viral administration will be approved for treatment of human patients. In this study, we have explored the outcome of the single iv injection of viral vector at post-natal day 10 (PND10). This has resulted in increased GALC activity in the central nervous system (CNS) and high GALC activity in the peripheral nervous system (PNS). As we have shown previously, an iv injection of AAVrh10 at PND2 results in a small extension of life beyond the typical lifespan of the untreated twi mice (~40 days). In this study, we report that mice receiving a single iv injection at PND10 had no tremor and continued to gain weight until a few weeks before they died. On average, they lived 20-25 days longer than untreated mice. We anticipate that this strategy in combination with other therapeutic options may be beneficial and applicable to treatment of human patients. PMID:25533112

    Background Diabetic macular edema (DME) is one of the major causes of visual impairment in patients with diabetes mellitus.DME shows a variety of clinical characteristics with unpredictable results to treatment.The purpose of this study was to investigate the characteristics of fundus autofluorescence (FAF) in DME,which is a rapid,noninvasive technique for fundus diseases.Methods A total of 18 patients (30 eyes) with clinically significant macular edema (CSME) were enrolled.FAF imaging was performed with a confocal scanning laser ophthalmoscope.Other ophthalmic examinations included best corrected visual acuity (BCVA),MP-1 microperimetry,and spectral-domain optical coherence tomography (SD-OCT).Main outcome measurements included BCVA,macular sensitivity (MS),central retinal thickness (CRT),central retinal volume (CRV),the integrity of the inner segment-outer segment junction (IS/OS),and the integrity of the external limiting membrane (ELM).Results Among the 30 eyes,four eyes (13.3%) had normal foveal FAF and 26 eyes (86.7%) had abnormal FAF.Abnormal FAF was mainly divided into three types:cystoid increased FAF (iFAF) 16 eyes (53.3%),spot iFAF six eyes (20%),irregular decreased FAF (dFAF) four eyes (13.3%).According to the FAF morphology,patients were categorized into four groups:normal,cystoid iFAF,spot iFAF,and irregular dFAF.There was a significant difference in BCVA (P <0.001) and MS (P <0.05) among the four groups.The visual function of patients with spot iFAF and irregular dFAF was relatively poor.However,there was no difference in CRT (P=-0.186) and CRV (P=0.191) among the four groups.In the normal FAF group,the photoreceptor layers were mostly intact.Regarding the cystoid iFAF group,the photoreceptor layers were relatively intact,while in the other two groups,IS/OS and ELM were disrupted in most patients.No one had intact IS/OS or ELM layer.Conclusions FAF might reflect the damage of the retina and had a relationship with visual function as

    Wear of low-oxygen-transmissible soft contact lenses swells the cornea significantly, even during open eye. Although oxygen-deficient corneal edema is well-documented, a self-consistent quantitative prediction based on the underlying metabolic reactions is not available. We present a biochemical description of the human cornea that quantifies hypoxic swelling through the coupled transport of water, salt, and respiratory metabolites. Aerobic and anaerobic consumption of glucose, as well as acidosis and pH buffering, are incorporated in a seven-layer corneal model (anterior chamber, endothelium, stroma, epithelium, postlens tear film, contact lens, and prelens tear film). Corneal swelling is predicted from coupled transport of water, dissolved salts, and especially metabolites, along with membrane-transport resistances at the endothelium and epithelium. At the endothelium, the Na+/K+ - ATPase electrogenic channel actively transports bicarbonate ion from the stroma into the anterior chamber. As captured by the Kedem-Katchalsky membrane-transport formalism, the active bicarbonate-ion flux provides the driving force for corneal fluid pump-out needed to match the leak-in tendency of the stroma. Increased lactate-ion production during hypoxia osmotically lowers the pump-out rate requiring the stroma to swell to higher water content. Concentration profiles are predicted for glucose, water, oxygen, carbon dioxide, and hydronium, lactate, bicarbonate, sodium, and chloride ions, along with electrostatic potential and pressure profiles. Although the active bicarbonate-ion pump at the endothelium drives bicarbonate into the aqueous humor, we find a net flux of bicarbonate ion into the cornea that safeguards against acidosis. For the first time, we predict corneal swelling upon soft-contact-lens wear from fundamental biophysico-chemical principles. We also successfully predict that hypertonic tear alleviates contact-lens-induced edema. PMID:21820076

    Full Text Available Due to the importance of clinically significant macular edema in diabetic patients, this study is aimed to determine if laser photocoagulation is effective in the treatment of clinically significant diabetic macular edema. In addition, the effects of risk factors arc surveyed* This is an existing data study considering patients with clinically significant diabetic macular edema, treated with argon-green laser photocoagulation in Labbafinejad hospital, department of lasertherapy, from 1995 to 1997. in 60 (42.6% eyes the treatment method was focal, in 22 (15.6% eyes grid, and in 59 (41.84 modified grid laser photocoagulation was performed. The results are based upon deterioration of visual acuity, occurance of moderate visual loss and improvement or persistence of CSME. We studied 114 eyes from 87 patients. Two years after initial treatment, visual acuity improved in 19.1% of eyes, unchanged in 9.5% and worsened in 71.4% of eyes. After this period the rate of moderate visual loss was 28.6% and CSME was improved in 23.8% of eyes. According to our study, baseline visual acuity and retinopathy severity were two important intervening factors in response to lasertherapy. Comparing our results with natural course of diabetic macular edema, indicates that in assessing visual outcome laser photocoagulation is an effective modality in treatment of CSME, but it is not effective in maintaining or improving visual acuity, which is due to patients delay in visiting ophthalmologists and paying not enough attention to follow-up visits.

    Full Text Available Background: To report the anatomic and visual acuity response after intravitreal bevacizumab (Avastin in patients with diffuse diabetic macular edema. Design: Prospective, interventional case series study. Materials and Methods: This study included 20 eyes of metabolically stable diabetes mellitus with diffuse diabetic macular edema with a mean age of 59 years who were treated with two intravitreal injections of bevacizumab 1.25 mg in 0.05 ml six weeks apart. Main outcome measures were 1 early treatment diabetic retinopathy study visual acuity, 2 central macular thickness by optical coherence tomography imaging. Each was evaluated at baseline and follow-up visits. Results: All the eyes had received some form of laser photocoagulation before (not less than six months ago, but all of these patients had persistent diffuse macular edema with no improvement in visual acuity. All the patients received two injections of bevacizumab at an interval of six weeks per eye. No adverse events were observed, including endophthalmitis, inflammation and increased intraocular pressure or thromboembolic events in any patient. The mean baseline acuity was 20/494 (log Mar=1.338±0.455 and the mean acuity at three months following the second intravitreal injection was 20/295 (log Mar=1.094±0.254, a difference that was highly significant ( P =0.008. The mean central macular thickness at baseline was 492 µm which decreased to 369 µm ( P =0.001 at the end of six months. Conclusions: Initial treatment results of patients with diffuse diabetic macular edema not responding to previous photocoagulation did not reveal any short-term safety concerns. Intravitreal bevacizumab resulted in a significant decrease in macular thickness and improvement in visual acuity at three months but the effect was somewhat blunted, though still statistically significant at the end of six months.

    Full Text Available Introduction. Family physicians have more opportunities to attend athletic competitions as medical staff at first-aid centers because of the increasing popularity of endurance sports. Case. A 38-year-old man who participated in a triathlon race experienced difficulty in breathing after swimming and was moved to a first-aid center. His initial oxygen saturation was 82% and a thoracic computed tomography scan showed bilateral ground glass opacity in the peripheral lungs. His diagnosis was noncardiogenic pulmonary edema associated with exercise or swimming: exercise-induced pulmonary edema (EIPE or swimming-induced pulmonary edema (SIPE. Treatment with furosemide and corticosteroid relieved his symptoms of pulmonary edema. Discussion. Noncardiogenic pulmonary edema associated with endurance sports is not common, but knowledge about EIPE/SIPE or neurogenic pulmonary edema associated with hyponatremia, which is called Ayus-Arieff syndrome, is crucial. Knowledge and caution for possible risk factors, such as exposure to cold water or overhydration, are essential for both medical staff and endurance athletes. Conclusion. To determine the presence of pulmonary edema associated with strenuous exercise, oxygen saturation should be used as a screening tool at a first-aid center. To avoid risks for EIPE/SIPE, knowledge about these diseases is essential for medical staff and for athletes who perform extreme exercise.

  12. Fetal trauma: brain imaging in four neonates

    International Nuclear Information System (INIS)

    The purpose of this paper is to describe brain pathology in neonates after major traffic trauma in utero during the third trimester. Our patient cohort consisted of four neonates born by emergency cesarean section after car accident in the third trimester of pregnancy. The median gestational age (n=4) was 36 weeks (range: 30-38). Immediate post-natal and follow-up brain imaging consisted of cranial ultrasound (n=4), computed tomography (CT) (n=1) and post-mortem magnetic resonance imaging (MRI) (n=1). Pathology findings were correlated with the imaging findings (n=3). Cranial ultrasound demonstrated a huge subarachnoidal hemorrhage (n=1), subdural hematoma (n=1), brain edema with inversion of the diastolic flow (n=1) and severe ischemic changes (n=1). In one case, CT demonstrated the presence and extension of the subarachnoidal hemorrhage, a parietal fracture and a limited intraventricular hemorrhage. Cerebellar hemorrhage and a small cerebral frontal contusion were seen on post-mortem MRI in a child with a major subarachnoidal hemorrhage on ultrasound. None of these four children survived (three children died within 2 days and one child died after 1 month). Blunt abdominal trauma during pregnancy can cause fetal cranial injury. In our cases, skull fracture, intracranial hemorrhage and hypoxic-ischemic encephalopathy were encountered. (orig.)

    Full Text Available Introduction: Neonatal hypernatremia dehydration (NHD is a dangerous condition in neonates, which is accompanied by acute complications (renal failure, cerebral edema, and cerebral hemorrhage and chronic complications (developmental delay. Children begin learning language from birth, and hearing impairment interferes with this process. We assessed the hearing status of infants with hypernatremia dehydration.   Materials and Methods: In a case-control study in 110 infants presenting at the Ghaem Hospital (Mashhad, Iran between 2007 and 2011, we examined the incidence of hearing impairment in infants suffering from hypernatremia dehydration (serum sodium >150 mEq/L in comparison with infants with normal sodium level (serum sodium ≤150 mEq/L.   Results: Three of 110 cases examined in the study group showed a transient hearing impairment. A mean serum sodium level of 173mg/dl was reported among hearing-impaired infants.   Conclusion:  Transient hearing impairment was higher in infants with hypernatremia; although this difference was not significant (P>0.05. Hearing impairment was observed in cases of severe hypernatremia.

    Diabetic macular edema (DME) can cause blindness in diabetic patients suffering from diabetic retinopathy (DR). DM parameters controls (glycemia, arterial tension, and lipids) are the gold standard for preventing DR and DME. Although the vascular endothelial growth factor (VEGF) is known to play a role in the development of DME, the pathological processes leading to the onset of this disease are highly complex and the exact sequence in which they occur is still not completely understood. Angiogenesis and inflammation have been shown to be involved in the pathogenesis of this disease. However, it still remains to be clarified whether angiogenesis following VEGF overexpression is a cause or a consequence of inflammation. This paper provides a review of the data currently available, focusing on VEGF, angiogenesis, and inflammation. Our analysis suggests that angiogenesis and inflammation act interdependently during the development of DME. Knowledge of DME etiology seems to be important in treatments with anti-VEGF or anti-inflammatory drugs. Current diagnostic techniques do not permit us to differentiate between both etiologies. In the future, diagnosing the physiopathology of each patient with DME will help us to select the most effective drug.

    The ultrasonic method was used in acute experiments on cats with open chest under artificial lung ventilation to obtain blood flow in low-lobar pulmonary artery and vein, the blood pressure in pulmonary artery, as well as the left atrial pressure in fat (olive oil) and mechanical (Lycopodium spores) pulmonary embolism. It is shown that pulmonary embolism produces the decrease in the blood flow in pulmonary artery and vein, the increase of the pressure in pulmonary artery and left atria, the increase of lung vessels resistance. The decrease is observed of systemic arterial pressure, bradycardia, and extrasystole. After 5-10 min the restoration of arterial pressure and heart rhythm occur and partial restoration of blood flow in pulmonary artery and vein. In many experiments the blood flow in vein outdoes that in the artery--it allows to suppose the increase of the blood flow in bronchial artery. After 60-90 min there occur sudden decrease of systemic arterial pressure, the decrease of the blood flow in pulmonary artery and vein. The pressure in pulmonary artery and resistance of pulmonary vessels remain high. Pulmonary edema developed in all animals. The death occurs in 60-100 min after the beginning of embolism.

Important progresses in modern perinatal care has resulted in a significantly improved survival and decreased morbidity, in both term and preterm infants. Most of these improvements are directly related to the better management of neonatal lung conditions, and infants of very low gestational ages are now surviving. This article reviews the common spectrum of diseases of the neonatal lung, including medical and surgical conditions, with emphasis to the radiological contribution in the evaluation and management of these infants. Imaging evaluation of the neonatal chest, including the assessment of catheters, lines and tubes are presented.

  1. The neonatal chest

    International Nuclear Information System (INIS)

    Lung diseases represent one of the most life threatening conditions in the newborn. Important progresses in modern perinatal care has resulted in a significantly improved survival and decreased morbidity, in both term and preterm infants. Most of these improvements are directly related to the better management of neonatal lung conditions, and infants of very low gestational ages are now surviving. This article reviews the common spectrum of diseases of the neonatal lung, including medical and surgical conditions, with emphasis to the radiological contribution in the evaluation and management of these infants. Imaging evaluation of the neonatal chest, including the assessment of catheters, lines and tubes are presented

    Melatonin has been shown to diminish edema in rats. Melatonin can be used to treat spinal cord injury. This study presumed that melatonin could relieve spinal cord edema and examined how it might act. Our experiments found that melatonin (100 mg/kg, i.p.) could reduce the water content of the spinal cord, and suppress the expression of aquaporin-4 and glial ifbrillary acidic protein after spinal cord injury. This suggests that the mechanism by which melatonin alleviates the damage to the spinal cord by edema might be related to the expression of aquaporin-4 and glial ifbrillary acidic protein.

    The aim of this study was to investigate if acute myocardial infarction can be detected by post-mortem cardiac magnetic resonance (PMMR) at an earlier stage than by traditional autopsy, i.e., within less than 4 h after onset of ischemia; and if so, to determine the characteristics of PMMR findings in early acute infarcts. Twenty-one ex vivo porcine hearts with acute myocardial infarction underwent T2-weighted cardiac PMMR imaging within 3 h of onset of iatrogenic ischemia. PMMR imaging findings were compared to macroscopic findings. Myocardial edema induced by ischemia and reperfusion was visible on PMMR in all cases. Typical findings of early acute ischemic injury on PMMR consist of a central zone of intermediate signal intensity bordered by a rim of increased signal intensity. Myocardial edema can be detected on cardiac PMMR within the first 3 h after the onset of ischemia in porcine hearts. The size of myocardial edema reflects the area of ischemic injury in early acute (per-acute) myocardial infarction. This study provides evidence that cardiac PMMR is able to detect acute myocardial infarcts at an earlier stage than traditional autopsy and routine histology.

    Full Text Available Childbirth is generally time of joy for parents and families. As per the medical reports each year 4 million newborns die within 28 days of birth and more suffer from disability, disease, infection and injury. The enabling environment for safe childbirth depends on the care and attention required to newborns by health personnel and the availability of adequate health-care facilities, equipment, and medicines and emergency care when needed. Neonatal monitoring refers to the monitoring of vital physiological parameters of premature infants. Continuous health monitoring of the neonates provides crucial parameters for early detection of adverse events. Health monitoring for the neonates provides crucial parameters for urgent diagnoses and corresponding medical procedures, subsequently increasing the survival rates. In the present paper, we propose a proto type design of a neonatal monitoring system. The system is designed and integrated with different health measurement and display devices. The prototype design is very much useful for monitor the physiological parameters of infants.

    Full Text Available Prominence or even enlargement of one or both breasts is known in neonates. It is believed to be a physiological response to falling levels of maternal estrogen towards last trimester of pregnancy. This input stimulates prolactin release from the newborn's pituitary leading to transient neonatal breast enlargement. This phenomenon is independent of the gender of the neonate. It presents in the first few weeks of life and resolves subsequently. Often fluid discharge is noted from the prominent or swollen breast that resolves without treatment in subsequent weeks. Manual breast manipulation for discharge removal may lead to undesirable effects like local irritation, enhanced enlargement, prolonged tissue hypertropy or even mastitis. A case of such 7-days female neonate is presented here backed with imaging evaluation for confirmation of diagnosis. Typical sonomammographic findings are described.

    Gestational substance exposure continues to be a significant problem. Neonates may be exposed to various substances including illicit drugs, prescription drugs, and other legal substances that are best not used during pregnancy because of their potential deleterious effects as possible teratogens or their potential to create dependence and thus withdrawal in the neonate. Screening the newborn for gestational substance exposure is important for both acute care and early intervention to promote the best possible long-term outcomes. This column provides insight into what is known about the extent of substance use by pregnant women, an overview of neonatal biologic matrices for drug testing, and a discussion of the legal implications of neonatal substance screening.

    Congenital heart disease (CHD) increases the risk of adverse maternal and neonatal outcomes. However, previous studies have included mainly women with low-risk features. A single-center, retrospective analysis of pregnant women with CHD was performed. Inclusion criteria were the following high-risk congenital lesions and co-morbidities: maternal cyanosis; New York Heart Association (NHYA) functional class >II; severe ventricular dysfunction; maternal arrhythmia, single ventricle (SV) physiology, severe left-sided heart obstruction and severe pulmonary arterial hypertension. Multivariate analyses for predictors of adverse maternal cardiovascular and neonatal outcomes were performed. Forty-three women reported 61 pregnancies. There were no maternal or neonatal deaths. Maternal cardiac (31%) and neonatal (54%) complications were frequent. The most frequent cardiac events were pulmonary edema, arrhythmia, and reduced NYHA class. Previous arrhythmia conferred a 12-fold increase in the odds of experiencing at least one major cardiac complication. Maternal SV physiology was an independent risk factor for low birth weight, risk of neonatal intensive care unit admission and lower gestational age. Maternal cyanosis and severe pulmonary arterial hypertension also predicted adverse neonatal outcomes. In conclusion, mothers without antepartum arrhythmia or functional incapacity are unlikely to experience arrhythmias or a decrease in NYHA class during pregnancy. In addition, SV physiology is a robust predictor of neonatal complications. Antepartum counseling and assessment of maternal fitness are crucial for the woman with CHD. PMID:27055756

    Full Text Available Background: Annual pilgrimage (Yatra to the cave shrine of Shri Amarnath Ji′ is a holy ritual among the Hindu devotees of Lord Shiva. Located in the Himalayan Mountain Range (altitude 13,000 ft in south Kashmir, the shrine is visited by thousands of devotees and altitude sickness is reportedly common. Materials and Methods: More than 600,000 pilgrims visited the cave shrine in 2011 and 2012 with 239 recorded deaths. Thirty one patients with suspected altitude sickness were referred from medical centers en-route the cave to Sher-i-Kashmir Institute of Medical Sciences, a tertiary-care center in capital Srinagar (5,000 ft. The clinical features and the response to treatment were recorded. Results: Thirty-one patients (all lowlanders, 19 male; age 18-60 years, median 41 had presented with acute onset breathlessness of 1-4 days (median 1.9 d starting within 12-24 h of a rapid ascent; accompanied by cough (68%, headache (8%, dizziness and nausea (65%. Sixteen patients had associated encephalopathy. Clinical features on admission included tachypnea ( n = 31, tachycardia ( n = 23, bilateral chest rales ( n = 29, cyanosis ( n = 22 and grade 2-4 encephalopathy. Hypoxemia was demonstrable in 24 cases and bilateral infiltrates on radiologic imaging in 29. Ten patients had evidence of high-altitude cerebral edema. All patients were managed with oxygen, steroids, nifedipine, sildenafil and other supportive measures including invasive ventilation ( n = 3. Three patients died due to multiorgan dysfunction. Conclusions: Altitude sickness is common among Amaranath Yatris from the plains and appropriate educational strategies should be invoked for prevention and prompt treatment.

  13. Mathematical modelling of blood-brain barrier failure and edema

    Injuries such as traumatic brain injury and stroke can result in increased blood-brain barrier permeability. This increase may lead to water accumulation in the brain tissue resulting in vasogenic edema. Although the initial injury may be localised, the resulting edema causes mechanical damage and compression of the vasculature beyond the original injury site. We employ a biphasic mixture model to investigate the consequences of blood-brain barrier permeability changes within a region of brain tissue and the onset of vasogenic edema. We find that such localised changes can indeed result in brain tissue swelling and that the type of damage that results (stress damage or strain damage) depends on the ability of the brain to clear edema fluid.

    2011-12-01

    Neonatal renal vein thrombosis (RVT) continues to pose significant challenges for pediatric hematologists and nephrologists. The precise mechanism for the onset and propagation of renal thrombosis within the neonatal population is unclear, but there is suggestion that acquired and/or inherited thrombophilia traits may increase the risk for renal thromboembolic disease during the newborn period. This review summarizes the most recent studies of neonatal RVT, examining its most common features, the prevalence of acquired and inherited prothrombotic risk factors among these patients, and evaluates their short and long term renal and thrombotic outcomes as they may relate to these risk factors. Although there is some consensus regarding the management of neonatal RVT, the most recent antithrombotic therapy guidelines for the management of childhood thrombosis do not provide a risk-based algorithm for the acute management of RVT among newborns with hereditary prothrombotic disorders. Whereas neonatal RVT is not a condition associated with a high mortality rate, it is associated with significant morbidity due to renal impairment. Recent evidence to evaluate the effects of heparin-based anticoagulation and thrombolytic therapy on the long term renal function of these patients has yielded conflicting results. Long term cohort studies and randomized trials may be helpful to clarify the impact of acute versus prolonged antithrombotic therapy for reducing the morbidity that is associated with neonatal RVT.

    Considerable evidence has demonstrated that metformin can activate 5’-AMP-activated protein kinase (AMPK) signaling pathway, which plays a critical role in protection of endothelial cell permeability. Hence, the present study evaluated the effects of metformin on blood brain barrier permeability and AQP4 expression in vitro, and assessed the effects of metformin treatment on tumor-induced brain edema in vivo. Hypoxia or VEGF exposure enhanced bEnd3 endothelial cell monolayer permeability and attenuated the expression of tight junction proteins including Occludin, Claudin-5, ZO-1, and ZO-2. However, 0.5 mM metformin treatment protected bEnd3 endothelial cell monolayer from hypoxia or VEGF-induced permeability, which was correlated with increased expression of tight junction proteins. Furthermore, metformin treatment attenuated AQP4 protein expression in cultured astrocytes. Such an effect involved the activation of AMPK and inhibition of NF-κB. Finally, metformin treatment dose-dependently reduced glioma induced vascular permeability and cerebral edema in vivo in rats. Thus, our results suggested that metformin may protect endothelial cell tight junction, prevent damage to the blood brain barrier induced by brain tumor growth, and alleviate the formation of cerebral edema. Furthermore, since the formation of cytotoxic edema and AQP4 expression was positively correlated, our results indicated that metformin may reduce the formation of cytotoxic edema. However, given that AQP4 plays a key role in the elimination of cerebral edema, attenuation of AQP4 expression by metformin may reduce the elimination of cerebral edema. Hence, future studies will be necessary to dissect the specific mechanisms of metformin underlying the dynamics of tumor-induced brain edema in vivo.

Su abordaje adecuado es imprescindible para garantizar un buen pronostico a largo plazo. Desarrollo. Se actualizan las informaciones acerca de la hipoxia neonatal y se revisan publicaciones recientes acerca de los avances en su abordaje a traves de la medicina basada en evidencias. Conclusiones. La encefalopatia neonatal se puede clasificar desde el punto de vista clinico en tres niveles de intensidad. Usualmente, los casos leves tienen un buen pronostico, los casos de intensidad moderada tienen un 30% de posibilidad de secuelas y los de intensidad grave tienen mas del 70% de mortalidad, pero practicamente todos los supervivientes tendran secuelas. Los avances ocurrieron en dos areas: en el diagnostico, con nuevas tecnicas de EEG y RM, y en el tratamiento, con la aparicion de la hipotermia terapeutica. Existe la posibilidad de un uso futuro para la terapia con celulas madre. El pronostico depende de la clasificacion clinica, de los datos de neuroimagen y del EEG.

    Full Text Available Occurrence of peritumoral brain edema (PBE in meningiomas has been associated with several factors in recent years, although its pathophysiological mechanism has not yet been fully elucidated. The aim of this study was to analyze the correlation between the presence / degree of PBE and factors such as gender, age, size and histological subtype of tumor. We analyzed the MRI images of 74 patients operated on Hospital Beneficência Portuguesa de Porto Alegre for the presence / degree of PBE and data was statistically correlated with the parameters of the patient. PBE was present in 70.1% of patients. Tumors with higher volume had more PBE. Tumors of the olfactory groove showed more PBE than sphenoid wing and parassagittal tumors. Transitional subtype showed more PBE than fibroblastic and meningothelial subtypes.A presença de edema cerebral peritumoral (ECP em meningiomas tem sido associada a diversos fatores nos últimos anos, embora o seu mecanismo fisiopatológico ainda não tenha sido inteiramente elucidado. O objetivo desse estudo foi analisar a correlação entre a presença/grau de ECP e fatores como sexo, idade, volume e subtipo histológico do tumor. Foram analisadas imagens de RM de 74 pacientes operados no Hospital Beneficência Portuguesa de Porto Alegre quanto à presença/grau de ECP e os dados correlacionados estatisticamente com os parâmetros do paciente.

Since the time of the diagnosis, the condition had been refractory to both subtenon triamcinolone acetonide and a total of five injections with intravitreal ranibizumab. After the last injection with ranibizumab, central subfield mean thickness was 640 µm, and the best corrected visual acuity was 78 Early Treatment Diabetic Retinopathy Study letters. Following an intravitreal injection with a dexamethasone implant, the macular edema resolved at the next follow-up. The macular edema returned 187 days after the first injection and was treated with another intravitreal dexamethasone implant. Again, the macular edema subsided completely, and best corrected visual acuity improved to 84 Early Treatment Diabetic Retinopathy Study letters, a condition which was maintained through an additional 189 days of follow-up.Conclusion: Chronic PCME is traditionally a difficult condition to treat, but we are encouraged by the optimal response experienced with intravitreal sustained release dexamethasone implants in our patient whose longstanding PCME had been refractory to previous treatments with both

    OBJECTIVE: To review the recent medical literature on the treatment of neonatal jaundice, focusing on practical aspects that are relevant to pediatricians and neonatologists. SOURCES: An extensive review of the related literature was performed, also including the authors clinical experience in this field of investigation. SUMMARY OF THE FINDINGS: Jaundice is very common among infants during the first days of life. Several factors such as maternal and neonatal history have to be considered before implementing treatment. Significant advances have been made in the past few years concerning the treatment of jaundiced newborn infants. This review focuses on three forms of treatment of neonatal hyperbilirubinemia: phototherapy, exchange transfusion and the use of drugs to reduce serum bilirubin concentration. CONCLUSIONS: Nowadays, the in-depth knowledge about the mechanism of action of phototherapy, the development of intensified phototherapy units and the use of drugs to reduce bilirubin formation, have contributed to significantly decrease the need for exchange transfusion.

    The aim of this study was to investigate whether changes in the distribution of pulmonary blood flow and disturbances of the pulmonary microcirculation can be detected by use of inflow-outflow indicator-dilution measurements. In 18 anesthetized (N2O-piritramide) mongrel dogs 221 thermal-indocyanine green dye indicator dilution kinetics were recorded in the pulmonary artery and aorta after central venous indicator injection. The lagged normal density function was used as a model for the pulmonary transport functions for heat and dye. The parameters of the lagged normal density function were computed by a non-linear least squares procedure by iterative convolution. After baseline measurements, in nine dogs, pulmonary edema was induced by central venous application of oleic acid. In nine other dogs, measurements were performed before and after postural changes. Our data show that both the microvascular injury caused by oleic acid edema and the perfusion heterogeneity caused by orthostasis can be detected by the indicator dilution technique since the both relative dispersion and skewness of the transport functions for heat and dye were significantly increased after these interventions.

In 41 consecutive patients with BRVO aged 68.9 ± 10.0 years (22 women and 19 men, the area of capillary nonperfusion was measured by fluorescein angiography. Retinal thickness and retinal volume were measured by optical coherence tomography, and mean retinal sensitivity was calculated for each of 9 macular subfields. Mean visual acuity and macular sensitivity within the central subfield were not significantly correlated with the nonperfused area. However, the macular sensitivity within the central 5 subfields and all 9 subfields showed significant negative correlations with the nonperfused area. Also, macular thickness and volume within all 9 subfields were significantly correlated with the nonperfused area. In conclusion, evaluation of both the fovea and the entire macular region may be important in patients with ischemic BRVO.Keywords: branch retinal vein occlusion, macular edema, macular sensitivity, ischemia

    Neonatal lupus erythematosus (NLE) is an uncommon disease of the neonate. It is believed to be caused by the transplacental passage of maternal autoantibodies to the ribonucleoproteins (Ro\\/SSA, La\\/SSB or rarely U RNP) as these are almost invariably present in NLE sera. The most common clinical manifestations include cutaneous lupus lesions and congenital complete heart block. Hepatobiliary and haematologic abnormalities are reported less frequently. We describe a patient with cutaneous NLE to illustrate and raise awareness of the characteristic annular eruption of this condition. We also emphasize the need for thorough investigation for concomitant organ involvement and for maternal education regarding risk in future pregnancies.

    Ultrasonography (US) is as an important tool for differentiation of obstructive and non-obstructive causes of jaundice in infants and children. Beyond two weeks of age, extrahepatic biliary atresia and neonatal hepatitis are the two most common causes of persistent neonatal jaundice: differentiation of extrahepatic biliary atresia, which requires early surgical intervention, is very important. Meticulous analysis should focus on size and configuration of the gallbladder and anatomical changes of the portahepatis. In order to narrow the differential diagnosis, combined approaches using hepatic scintigraphy, MR cholangiography, and, at times, percutaneous liver biopsy are necessary. US is useful for demonstrating choledochal cyst, bile plug syndrome, and spontaneous perforation of the extrahepatic bile duct

    Ischemic edema can alter the structure and permeability of the blood-brain barrier. Recent stud-ies have reported that progesterone reduces cerebral edema after cerebral ischemia. However, the underlying mechanism of this effect has not yet been elucidated. In the present study, pro-gesterone effectively reduced Evans blue extravasation in the ischemic penumbra, but not in the ischemic core, 48 hours after cerebral ischemia in rats. Progesterone also inhibited the down-reg-ulation of gene and protein levels of occludin and zonula occludens-1 in the penumbra. These results indicate that progesterone may effectively inhibit the down-regulation of tight junctions, thereby maintaining the integrity of the blood-brain barrier and reducing cerebral edema.

    Full Text Available Massive ovarian edema is a very rare disease characterized by a tumor like enlargement of the ovary. The presenting symptoms are non - specific and often the condition is mistaken for an ovarian neoplasm. A 28 year old nulligravid a lady , presented with chronic pain abdomen and irregular menses to our gynecological outpatient department. Ultrasound was suspicious of an ovarian neoplasm , but all biochemical parameters , including ovarian tumor markers were within normal limits. Considering the young age of the patient , laparotomy was done , and the mass excised. On histopathologi cal examination the diagnosis of massive ovarian edema was made. We present this case , not only because if its rarity , but also to stress on the fact that massive ovarian edema should be considered in the differential diagnosis of unilateral ovarian masses especially in young patients to avoid aggressive treatment as compromising fertility and hormonal function is always an issue

    Full Text Available We describe a patient with Kawasaki disease (KD and retropharyngeal edema following a blackfly bite. An 8-year-old boy was referred to our hospital because of a 3-day-history of fever and left neck swelling and redness after a blackfly bite. Computed tomography of the neck revealed left cervical lymph nodes swelling with edema, increased density of the adjacent subcutaneous tissue layer, and low density of the retropharyngeum. The patient was initially presumed to have cervical cellulitis, lymphadenitis, and retropharyngeal abscess. He was administered antibiotics intravenously, which did not improve his condition. The patient subsequently exhibited other signs of KD and was diagnosed with KD and retropharyngeal edema. Intravenous immunoglobulin therapy and oral flurbiprofen completely resolved the symptoms and signs. A blackfly bite sometimes incites a systemic reaction in humans due to a hypersensitive reaction to salivary secretions, which may have contributed to the development of KD in our patient.

    Bone marrow edema syndrome of the femoral head in pregnant women is a rare disease resulting in disabling coxalgia, beginning in the last 3 months of pregnancy and persisting for several months after parturition. The parenteral administration of the vasoactive drug iloprost constitutes a new approach to the treatment of painful bone marrow edema syndrome of the hip of pregnant women. Six postpartal women (8 hips) with bone marrow edema syndrome of the femoral head were treated with iloprost followed by 3 weeks of partial weight-bearing. Relief from pain, restoration of functional capacity, and normalization of the MRI signal pattern were rapidly achieved, thus avoiding the need for surgical intervention. As the substance is contraindicated in pregnancy, therapy may begin only some days after parturition, with a short discontinuation in breastfeeding.

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index 30 mmHg) and absent or reduced diuresis (shock associated with ischaemic heart disease.

    Nurses comprise a key component to maternal and newborn health care delivery, including the care of 'at-risk' or sick newborns. However, the efficiency and effectiveness of services rely heavily on adequate numbers of highly skilled neonatal nurses. Currently, in India, a significant shortage of trained nurses in the field of newborn care is contributing to poor neonatal outcomes. Specifically, nurses caring for newborns lack the competency and experience needed to ensure optimal care. This deficiency has been linked to a lack of expert faculty, standardized training and minimal or no exposures to newborn clinical care areas during pre service education. Moreover, in addition to a lack of operational research in the area, nurses who provide care for newborns are often faced with numerous system related issues that impede their ability to provide optimal care. Most notably, frequent changes of work place, poor wages, and lack of continuing education, skill maintenance, recognition, and collaborative team culture further compromise the nursing care. All these lead to poor motivation and competency. To meet this challenge, it is essential that emphasis be placed on the identification and support of nursing faculty with expertise in newborn and neonatal care who are able to ensure that nurses receive standardized education for pre-service, in-service and ongoing care. In addition, importance should be placed on encouraging newborn nursing research as well as on governmental increases in salary compensation. Lastly, given the shortage of physicians to take care of sick neonates in remote areas, the creation of a cadre of Neonatal nurse practitioner/ advanced practice nurses would be an invaluable solution in developing countries. Furthermore, centralized oversight of newborn education and training would be best served, if responsibility was placed with Reproductive maternal newborn child health (RMNCH) workers and district level officers.

    Brain edema can be classified into three categories: vasogenic, cytotoxic, and interstitial. The mechanism of edema is thought to be different in each type. The authors studied the movement of water molecules in each type of white matter edema in a rat model by using diffusion-weighted magnetic resonance imaging. Conventional T2-weighted imaging did not allow distinction between the three types of white matter edema; the three types of edema were, however, distinguished by using diffusion-weighted imaging. The apparent diffusion coefficient (ADC) of water was different in each type of edema. Water molecules in cytotoxic edema induced by triethyl-tin intoxication showed a smaller and less anisotropic ADC than in normal white matter. In contrast, water in vasogenic edema induced by cold injury had a larger and more anisotropic ADC than in normal white matter. Water in interstitial edema due to kaolin-induced hydrocephalus had an anisotropic and very large ADC. PMID:8280975

    Full Text Available Introduction: Hyperbilirubinemia is a relatively common disorder among infants in Iran. Bacterial infection and jaundice may be associated with higher morbidity. Previous studies have reported that jaundice may be one of the signs of infection. The aim of this study was to determine the incidence rate, presentation time, severity of jaundice, signs and complications of infection within neonatal hyperbilirubinemia.   Materials and Methods: This cross sectional study was conducted between 2003 and 2011, at Ghaem Hospital, Mashhad- Iran. We prospectively evaluated 1763 jaundiced newborns. We Finally found 434 neonates who were categorized into two groups.131 neonates as case group (Blood or/and Urine culture positive or sign of pneumonia and 303 neonates with idiopathic jaundice as control group. Demographic data including prenatal, intrapartum, postnatal events and risk factors were collected by questionnaire. Biochemical markers including bilirubin level, urine and blood cultures were determined at the request of the clinicians.   Results: Jaundice presentation time, age on admission, serum bilirubin value and hospitalization period were reported significantly higher among case group in comparison with control group (p

    Objective To review the role of epigenetic regulation in neonatal diseases and better understand Barker's "fetal origins of adult disease hypothesis".Data sources The data cited in this review were mainly obtained from the articles published in Medline/PubMed between January 1953 and December 2009.Study selection Articles associated with epigenetics and neonatal diseases were selected.Results There is a wealth of epidemiological evidence that lower birth weight is strongly correlated with an increased risk of adult diseases, such as type 2 diabetes mellitus, hypertension, and cardiovascular disease. This phenomenon of fetal origins of adult disease is strongly associated with fetal insults to epigenetic modifications of genes. A potential role of epigenetic modifications in congenital disorders, transient neonatal diabetes mellitus (TNDM), intrauterine growth retardation (IUGR), and persistent pulmonary hypertension of the newborn (PPHN) have been studied.Conclusions Acknowledgment of the role of these epigenetic modifications in neonatal diseases would be conducive to better understanding the pathogenesis of these diseases, and provide new insight for improved treatment and prevention of later adult diseases.

    Introduccion. La leucinosis es una metabolopatia neonatal grave. Es consecuencia del deficit enzimatico determinado geneticamente del complejo descarboxilasa-dihidrolipoil transacilasa y dihidrolipoil deshidrogenasa, y del acumulo consecuente de los metabolitos precursores, aminoacidos ramificados de cadena larga y sus alfa-cetoacidos. Son potentes neurotoxicos, responsables del rapido establecimiento de edema y desmielinizacion cerebral difusa. La demora en el diagnostico suele provocar graves secuelas psicomotoras o incluso la muerte. Caso clinico. Se presenta una paciente neonata con encefalopatia neonatal grave, crisis epilepticas y un electroencefalograma (EEG) con unas caracteristicas especiales que oriento el diagnostico hacia una posible leucinosis. El diagnostico temprano permitio instaurar rapidamente el tratamiento especifico y conseguir una evolucion favorable de la paciente. Conclusiones. El EEG en pacientes con sospecha de encefalopatia neonatal ofrece informacion funcional de alta rentabilidad con un bajo coste, en especial por promover diagnosticos y tratamientos tempranos. El EEG en la leucinosis presenta signos peculiares, reconocibles en periodos tempranos en la mayor parte de los afectados, como ocurrio en el caso descrito. Parece recomendable integrar el EEG en el cribado de encefalopatias neonatales por ser una tecnica diagnostica valiosa, inocua y, por lo general, accesible y especialmente de ayuda en metabolopatias tratables, como la leucinosis.

    During pregnancy, it is not always possible to identify maternal or foetal risk factors. Infants requiring specialised medical care are not always born in centres providing intensive care and will need to be transferred to a referral centre where intensive care can be provided. Therefore Neonatal Transport needs to be considered as part of the organisation of perinatal health care. The aim of Neonatal Transport is to transfer a newborn infant requiring intensive care to a centre where specialised resources and experience can be provided for the appropriate assessment and continuing treatment of a sick newborn infant. Intrauterine transfer is the ideal mode of transport when the birth of an infant with risk factors is diagnosed. Unfortunately, not all problems can be detected in advance with enough time to safely transfer a pregnant woman. Around 30- 50% of risk factors will be diagnosed during labour or soon after birth. Therefore, it is important to have the knowledge and resources to resuscitate and stabilise a newborn infant, as well as a specialised neonatal transport system. With this specialised transport it is possible to transfer newly born infants with the same level of care that they would receive if they had been born in a referral hospital, without increasing their risks or affecting the wellbeing of the newborn. The Standards Committee of the Spanish Society of Neonatology reviewed and updated recommendations for intrauterine transport and indications for neonatal transfer. They also reviewed organisational and logistic factors involved with performing neonatal transport. The Committee review included the type of personnel who should be involved; communication between referral and receiving hospitals; documentation; mode of transport; equipment to stabilise newly born infants; management during transfer, and admission at the referral hospital.

    Full Text Available PURPOSE: To study the factors that may affect reading speed in patients with diabetic macular edema previously treated with laser photocoagulation. METHODS: Consecutive patients with type II diabetes treated with laser photocoagulation for diabetic macular edema (DME at least twelve months previously, with best corrected visual acuity of better than 65 letters (approximately 20/40 measured with Early Treatment Diabetic Retinopathy Study (ETDRS charts were included in this study. Patients previously treated with pan-retinal photocoagulation, vitrectomy, intravitreal steroid or anti-VEGF therapy were excluded. Any other ocular co-morbidities that may influence reading ability such as cataract, glaucoma or macular degeneration were also excluded. All patients were refracted by a certified examiner, the following measurements were collected: best corrected visual acuity (BCVA, contrast sensitivity with Pelli-Robson chart, reading speed with MNREAD chart, microperimetry with Nidek MP1, and central subfield thickness with Zeiss spectral domain optical coherent topography. RESULTS: The slow reading group had poorer contrast sensitivity (p = 0.001, reduced retinal sensitivity (p = 0.027 and less stable fixation (p = 0.013. Most interestingly the reduced retinal sensitivity findings were driven by the microperimetry value on the right subfield (p = 0.033, (nasal to the fovea in the right eye and temporal to the fovea in the left eye. Multiple linear regression analysis showed that contrast sensitivity is probably the most important factor that affects reading speed (p = 0.001. CONCLUSION: Reduced retinal sensitivity after laser treatment is associated with reduced reading speed in patients with diabetic macular edema.

    Functional and molecular changes associated with pathophysiological conditions are relatively easily detected based on tissue samples collected from patients. Population specific cellular responses to disease might remain undiscovered in samples taken from organs formed by a multitude of cell types. This is particularly apparent in the human cerebral cortex composed of a yet undefined number of neuron types with a potentially different involvement in disease processes. We combined cellular electrophysiology, anatomy and single cell digital PCR in human neurons identified in situ for the first time to assess mRNA expression and corresponding functional changes in response to edema and increased intracranial pressure. In single pyramidal cells, mRNA copy numbers of AQP1, AQP3, HMOX1, KCNN4, SCN3B and SOD2 increased, while CACNA1B, CRH decreased in edema. In addition, single pyramidal cells increased the copy number of AQP1, HTR5A and KCNS1 mRNAs in response to increased intracranial pressure. In contrast to pyramidal cells, AQP1, HMOX1and KCNN4 remained unchanged in single cell digital PCR performed on fast spiking cells in edema. Corroborating single cell digital PCR results, pharmacological and immunohistochemical results also suggested the presence of KCNN4 encoding the α-subunit of KCa3.1 channels in edema on pyramidal cells, but not on interneurons. We measured the frequency of spontaneous EPSPs on pyramidal cells in both pathophysiological conditions and on fast spiking interneurons in edema and found a significant decrease in each case, which was accompanied by an increase in input resistances on both cell types and by a drop in dendritic spine density on pyramidal cells consistent with a loss of excitatory synapses. Our results identify anatomical and/or physiological changes in human pyramidal and fast spiking cells in edema and increased intracranial pressure revealing cell type specific quantitative changes in gene expression.

    Pathological detection results of uterus and placenta of neonatal rats: Uterine wall and placenta of pregnant rats were found with vascular engorgement and edema, and a great quantity of neutrophilic leukocyte infiltrated. Meanwhile, there was not evident inflammatory reaction in the pregnant rats in the control group. ④ Detection of brain tissue of neonatal rats under an electron microscope: Obvious brain injury was found in the neonatal rats of the experimental rats, but was not found in the control group. CONCLUSION: LPS successfully causes intrauterine infection of pregnant rats, and the neonatal rats born by which have obvious brain injury. Through detecting the changes of the content of MBP and S-100 on these animal models, it is concluded that MBP and S-100 can be used as the indexes to early diagnose brain injury, and they are the sensitive biochemical indexes to reflect the extent of early brain injury.

    PURPOSE:: To compare the effect of intravitreal diclofenac (IVD) versus intravitreal triamcinolone (IVT) on refractory uveitic cystoid macular edema. METHODS:: In this pilot, randomized, clinical trial, 15 eyes were randomly assigned to IVD group, patients (8 eyes) who received a single intravitreal injection of diclofenac (500 μg/0.1 mL), and IVT group (7 eyes) patients who received a single intravitreal injection of triamcinolone (2 mg). Change in best-corrected visual acuity in logarithm of the minimum angle of resolution at Week 36 was the primary outcome measure. Secondary outcomes included changes in best-corrected visual acuity (BCVA) at 12 weeks and 24 weeks, central macular thickness, macular leakage, and potential injection-related complications. RESULTS:: In the IVD group, BCVA was more than the baseline values in 4 eyes at 36 weeks; however, within-group analysis disclosed no statistically significant changes in the mean BCVA in this group. Nonetheless, in the IVT group, mean BCVA improved significantly at 12, 24, but not at 36 weeks compared with the baseline values. It was 0.86 ± 0.37 at baseline and 0.63 ± 0.48, 0.62 ± 0.42, and 0.43 ± 0.49 logarithm of the minimum angle of resolution at 12, 24, and 36 weeks, respectively. Mean central macular thickness diminished also significantly only in the IVT group. Nevertheless, comparing the mean BCVA and central macular thickness changes, macular leakage, and the occurrence of any injection-related complications, no significant difference was observed between the groups at any of the follow-up visits. CONCLUSION:: This pilot study demonstrated the superiority of IVT over IVD in the treatment of refractory uveitic cystoid macular edema regarding both functional and anatomical outcomes. Further studies are warranted to confirm potential benefit of IVD observed in this study. PMID:23584700

There are many natural and synthetic drugs for treatment of inflammation and lot of them are under investigation. Sodium valporate is an antiepileptic drug used particularly in the treatment of primary generalized seizure notably absence, myocolonic seizure, acute manic phase of bipolar disorder and prophylaxis of migraine. The previous observations showed sodium valporate increases level of gamma amino butyric acid (GABA in the central and peripheral nervous system. In acute inflammation, GABA showed a significant attenuation of paw edema and nociception. The aim of this study was evaluation of anti-inflammatory effect of sodium valporate. Materials & Methods: In order to evaluated the anti-inflammatory and antiexudative of sodium valporate doses of 200,400 and 600 mg/kg were investigated on rat paw edema that induced by carrageenan. In addition, the plasma leakage in the inflamed tissue was evaluated by application of trypan blue as intravenous injection. Dexamethason was used as positive control. Results: Results showed sodium valporate doses of 400 and 600 mg/kg decreased inflammatory and exudative effect as compared to control group. Conclusion: Although the anti-inflammatory mechanisms of this drug were not evident but we can say sodium valporate in addition to already proved effects has anti-inflammatory effect.

    To determine computed tomographic (CT) imaging characteristics of retropharygeal edema, we reviewed CT images in 18 patients with head and neck tumors. Retropharyngeal edema spread craniocaudally between soft palate and upper half of thyroid cartilage in all patients. No edema fluid extended above soft palate and below thyroid cartilage. Horizontally, it spread symmetrically in ten and asymmetrically in eight patients. Predominance in asymmetrical retropharyngeal edema was found on the same side as that of unilateral predominance both in lymph nodes enlargement and jugular vein stenosis/occlusion. All patients had edema also in other cervical spaces. Edema of retropharyngeal and other spaces fluctuated synchronously. In 14 patients, as primary lesion and/or cervical lymph nodes regressed, retropharyngeal edema disappeared or decreased. Retropharyngeal edema had some imaging characteristics. With knowledge of that, we could avoid diagnostic confusion when evaluating head and neck CT images. (orig.)

    The pediatric surgeon deals with a large number and variety of congenital defects in neonates that frequently involve early surgical intervention and care. Because the neonatal cardiac physiology is unique, starting with the transition from fetal circulation and including differences in calcium metabolism and myocardial microscopic structure and function, it serves the pediatric surgeon well to have a sound understanding of these principles and how they directly and indirectly affect their plans and treatments. In addition, many patients will have associated congenital heart disease that can also dramatically influence not only the surgical and anesthetic care but also the timing and planning of procedures. Finally, the pediatric surgeon is often called upon to treat conditions and complications associated with complex congenital heart disease such as feeding difficulties, bowel perforations, and malrotation in heterotaxy syndromes. In this article, we will review several unique aspects of neonatal cardiac physiology along with the basic physiology of the major groups of congenital heart disease to better prepare the training and practicing pediatric surgeon for care of these complex and often fragile patients.

    As part of a study to determine the cause(s) of population decline and low survival of pronghorn (Antilocapra americana) neonates on Hart Mountain National Antelope Refuge (HMNAR), Oregon (USA), 55 of 104 neonates captured during May 1996 and 1997 were necropsied (n = 28, 1996; n = 27, 1997) to determine cause of death. Necropsies were conducted on fawns that died during May, June, or July of each year. The objectives of this study were to report the occurrence and pathology of pasteurellosis in neonates and determine if the isolated strain of Pasteurella multocida was unique. Septicemic pasteurellosis, caused by P. multocida, was diagnosed as the cause of death for two neonates in May and June 1997. Necropsy findings included widely scattered petechial and ecchymotic hemorrhages found over a large portion of the subcutaneous tissue, meninges of the brain, epicardium, skeletal muscle, and serosal surface of the thorasic and abdominal cavities. Histological examination of lung tissues revealed diffuse congestion and edema and moderate to marked multifocal infiltrate of macrophages, neutrophils, and numerous bacteria within many terminal bronchioles and alveoli. Pasteurella multocida serotypes A:3,4, and B:1 were isolated from several tissues including lung, intestinal, thorasic fluid, and heart blood. Each B:1 isolate had DNA restriction endonuclease fingerprint profiles distinct from isolates previously characterized from domestic cattle, swan (Olor spp.), moose (Alces alces), and pronghorn from Montana (USA). This is the first report of pasteurellosis in pronghorn from Oregon and the B:1 isolates appear to be unique in comparison to DNA fingerprint profiles from selected domestic and wild species.

    Vesoulis, Zachary A; Mathur, Amit M

    2014-06-01

    Seizures are more common in the neonatal period than any other time in the human lifespan. A high index of suspicion for seizures should be maintained for infants who present with encephalopathy soon after birth, have had a stroke, central nervous system (CNS) infection or intracranial hemorrhage or have a genetic or metabolic condition associated with CNS malformations. Complicating the matter, most neonatal seizures lack a clinical correlate with only subtle autonomic changes and often no clinical indication at all. Over the last three decades, several tools have been developed to enhance the detection and treatment of neonatal seizures. The use of electroencephalography (EEG) and the later development of amplitude-integrated EEG (aEEG), allows for Neurologists and non-Neurologists alike, to significantly increase the sensitivity of seizure detection. When applied to the appropriate clinical setting, time to diagnosis and start of therapy is greatly reduced. Phenobarbital maintains the status of first-line therapy in worldwide use. However, newer anti-epileptic agents such as, levetiracetam, bumetanide, and topiramate are increasingly being applied to the neonatal population, offering the potential for seizure treatment with a significantly better side-effect profile. Seizures in premature infants, continue to confound clinicians and researchers alike. Though the apparent seizure burden is significant and there is an association between seizures and adverse outcomes, the two are not cleanly correlated. Compounding the issue, GABA-ergic anti-epileptic drugs are not only less effective in this age group due to reversed neuronal ion gradients but may cause harm. Selecting an appropriate treatment group remains a challenge. PMID:24796413

Information was collected on maternal and infant health, social factors and pregnancy. NAS sheets were scrutinized. RESULTS: 220 women with reported 3rd trimester exposure to SSRIs or SNRIs and who gave birth between January 2007 and June 2009 were included. Seventy seven women (35% used citalopram, 76 used (35% sertraline, 34 (15% fluoxetine and 33 (15% other SSRI/SNRI. Twenty-nine infants (13% were admitted to the neonatal ward, 19 were born prematurely. NAS was analyzed in 205 patients. Severe abstinence was defined as eight points or higher on at least two occasions (on a scale with maximum 40 points, mild abstinence as 4 points or higher on at least two occasions. Seven infants expressed signs of severe abstinence and 46 (22% had mild abstinence symptoms. Hypoglycemia (plasma glucose <2.6 mmol/L was found in 42 infants (19%. CONCLUSION: Severe abstinence in infants prenatally exposed to antidepressants was found to be rare (3% in this study population, a slightly lower prevalence than reported in previous studies. Neonatal hypoglycemia in infants prenatally exposed to antidepressant may however be more common than previously described.

    Full Text Available Purpose: To describe optical coherence tomography (OCT findings in a patient with Berlin′s edema following blunt ocular trauma. Case Report: A 26-year-old man presented with acute loss of vision in his left eye following blunt trauma. He underwent a complete ophthalmologic examination and OCT. Fundus examination revealed abnormal yellow discoloration in the macula. OCT disclosed thickening of outer retinal structures and increased reflectivity in the area of photoreceptor outer segments with preservation of inner retinal architecture. Re-examination was conducted one month later at the time which OCT changes resolved leading to a surprisingly normal appearance. Conclusion: OCT can be a useful tool in the diagnosis and follow-up of eyes with Berlin′s edema and may reveal ultrastructural macular changes.

    Objective: To investigate the effects of magnesium sulfate on traumatic brain edema and explore its possible mechanism.Methods: Forty-eight Sprague-Dawley ( SD ) rats were randomly divided into three groups: Control, Trauma and Treatment groups. In Treatment group, magnesium sulfate was intraperitoneally administered immediately after the induction of brain trauma. At 24 h after trauma, total tissue water content and Na + , K + , Ca2 + , Mg2+ contents were measured. Permeability of blood-brain barrier (BBB)was assessed quantitatively by Evans Blue (EB) dye technique. The pathological changes were also studied.Results: Water, Na + , Ca2 + and EB contents in Treatment group were significantly lower than those in Trauma group ( P < 0. 05 ). Results of light microscopy and electron microscopy confirmed that magnesium sulfate can attenuate traumatic brain injury and relieve BBB injury.Conclusions: Treatment with MgSO4 in the early stage can attenuate traumatic brain edema and prevent BBB injury.

    Full Text Available We present a case of an 18-month-old boy who showed severe clinical signs indicative of acute hemorrhagic edema of infancy (AHEI with painful purpuric skin affection primarily of the face and marked edema of the ears. The histological findings were diagnostic for leukocytoclastic vasculitis and thus met the histological criteria for AHEI. Indicative of infection as causative agent for the condition were symptoms of gastroenteritis. High-dose intravenous corticosteroids led to a fast resolution of symptoms and normalization of laboratory parameters. AHEI is usually not described as being very responsive to corticosteroids. The case presented here indicates that severe cases of AHEI can be treated with high-dose intravenous corticosteroids resulting in significant relief and shortening of the symptoms. Clinical followup showed no underlying malignancy or other severe chronic systemic diseases thus confirming earlier reports that AHEI is not associated with such conditions. The differential diagnoses with AHEI are discussed.

    Full Text Available We report a case of ocular tuberculosis (TB which initially presented with disc edema and was mistaken for optic neuritis. With no definite pathology being identified, the patient was treated on the lines of optic neuritis with intravenous (IV steroid with beneficial effect. Ocular TB was suspected when he presented later with a subretinal abscess. Based on positive Mantoux, QuantiFERON TB gold results and radiographic findings, a diagnosis of subretinal abscess of presumed tubercular etiology was made. The patient was successfully treated with anti-tubercular therapy. To the best of our knowledge, this is the first case report of ocular TB presenting as disc edema followed by subretinal abscess.

    2014-01-01

    Diabetic macular edema (DME) is a retinal thickening involving the center of the macula. It is one of the serious eye diseases which affects the central vision and can lead to partial or even complete visual loss. The only cure is timely diagnosis, prevention, and treatment of the disease. This paper presents an automated system for the diagnosis and classification of DME using color fundus image. In the proposed technique, first the optic disc is removed by applying some preprocessing steps. The preprocessed image is then passed through a classifier for segmentation of the image to detect exudates. The classifier uses dynamic thresholding technique by using some input parameters of the image. The stage classification is done on the basis of anearly treatment diabetic retinopathy study (ETDRS) given criteria to assess the severity of disease. The proposed technique gives a sensitivity, specificity, and accuracy of 98.27%, 96.58%, and 96.54%, respectively on publically available database.

    Full Text Available Neurogenic pulmonary edema (NPE can result from various central nervous system disorders such as brain malignancies, traumatic brain injuries, infections, and seizures. Although the pathogenesis is not completely understood, NPE creates an increase in pulmonary interstitial and alveolar fluid. It has been reported with prolonged seizure activity. Treatment for NPE is largely supportive. If unrecognized, it can lead to hypoxia and respiratory arrest. We report a case of NPE in a middle-aged female patient following a breakthrough seizure in whom an immunological cause for respiratory findings was high on the differential list, based on her past medical history and chronicity of symptoms. Rapid symptomatic and radiological improvement following hospitalization led to the correct diagnosis.

    Two detailed reviews of the management of neonatal thrombosis were published in 2012; one was an up-dated version of guidance first issued in 2004 and the other was a comprehensive review. Both of these publications gave very similar advice regarding the practical aspects of the indications, dosage and management of antithrombotic therapy. The authors stated that the evidence supporting most of their recommendations for anti-thrombotic therapy in neonates remained weak and so the therapy for a neonate with a thrombosis has to be based on an individualized assessment of estimated risk versus potential benefit. The aim of this present review is to give the treating physician an outline of the unique physiology of neonatal coagulation and how this affects the monitoring, dosing and even the choice of therapeutic strategy for the management of thrombosis in the neonate.

    Diabetic macular edema is shown to be treated successfully by central focal argon laser coagulation in most cases. Since February 1986, diabetic patients with macular edema were evaluated prospectively and treated by focal argon laser coagulation and/or grid pattern. A second group of diabetic patients with comparable macular edema and similar retinal changes was explored retrospectively. Visual acuity after treatment in relation to preoperative visual acuity was measured and statistically compared with visual acuity of the second group without laser treatment. The results show that laser treatment is important for stabilization of visual acuity but does not increase visual acuity beneath 0.2. Indications for treatment are discussed. PMID:2587022

    It has been difficulty to visualize lymphatics in living patients. Conventional or direct lymphography has been the gold standard for delineation of the lymphatic system, but this procedure is invasive, difficulty to perform, and harmful to the lymphatic vascular endothelium. The aim of our study was to determine its severity, and to understand the drainage patterns on patients with peripheral edema by functional lymphatic studies. Tc-99m antimony sulfide colloid 25 MBq with 0.4 ml volume was injected intradermally in the first, second and third web space of the foot or hand in 40 patients with peripheral edema (5 in upper extremity and 35 in lower extremity). Initial flow after injection and whole body images at approximately 30 minutes. 1-4 hours were obtained. In 9/40 cases with peripheral edema normal lymphoscintigram were revealed, primary lymphedema was observed in 5/31 cases. The imaging patterns in primary lymphedema were absent (3 cases) or delayed (2 cases) transport, lymphatic duct dilatation (1), cutoff (1), decrease in size and number of lymph nodes (2). The Common caused of edema in secondry lymphedema (26/31) were carcinoma (13), inflammation (5), post-operation (5), and unknown origin (3). The common imaging findings in carcinoma showed non-visualization of lymph nodes (13), dermal backflow (8), collateral circulation (5), and in inflammation lymphatic obstruction (2), increase in size and number of lymph nodes (2), delayed transport (1), and in post-operation dermal backflow (3), delayed transport (2), decrease in number and size of lymph node (2) Clear images patterns were observed difference between primary lymphedema an secondary lymphedema. Radionuclide lymphoscintigraphy is essentially non-invasive, easy to perform repeatedly, and harmless to the lymphatic vascular endothelium for evaluation of a patient with lymphedema.

    Objective: To evaluate plasma arginine vasopressin (AVP) level in patients with traumatic brain injury and investigate the role of AVP in the process of brain edema. Methods: A total of 30 patients with traumatic brain injury were involved in our study. They were divided into two groups by Glasgow Coma Scale: severe traumatic brain injury group (STBI, GCS≤ 8) and moderate traumatic brain injury group (MTBI, GCS>8).Samples of venous blood were collected in the morning at rest from 15 healthy volunteers (control group)and within 24 h after traumatic brain injury from these patients for AVP determinations by radioimmunoassay. The severity and duration of the brain edema were estimated by head CT scan.Results: plasma AVP levels (ng/L) were (mean±SD): control, 3.06±1.49; MTBI, 38.12±7.25; and STBI, 66.61±17.10.The plasma level of AVP was significantly increased within 24 h after traumatic brain injury and followed by the reduction of GCS, suggesting the deterioration of cerebral injury (P<0.01). And the AVP level was correlated with the severity (STBI r=0.919, P<0.01; MTBI r=0.724, P<0.01) and the duration of brain edema (STBI r=0.790, P<0.01; MTBI r=0.712, P<0.01). Conclusions: The plasma AVP level is closely associated with the severity of traumatic brain injury. AVP may play an important role in pathogenesis of brain edema after traumatic brain injury.

  14. Significance of bone marrow edema in pathogenesis of rheumatoid arthritis

    International Nuclear Information System (INIS)

    Assessing the pathology of the synovium, its thickening and increased vascularity through ultrasound and magnetic resonance examinations (more often an ultrasound study alone) is still considered a sensitive parameter in the diagnosis of rheumatoid arthritis and in monitoring of treatment efficacy. Magnetic resonance studies showed that, aside from the joint pannus, the subchondral bone tissue constitutes an essential element in the development of rheumatoid arthritis. Bone marrow edema correlates with inflammation severity, joint destruction, clinical signs and symptoms of rheumatoid arthritis, and thus is considered a predictor of rapid radiological progression of the disease. The newest studies reveal that bone marrow edema may be a more sensitive indicator of the response to therapy than appearance of the synovium. Bone marrow edema presents with increased signal in T2-weighted images, being most visible in fat saturation or IR sequences (STIR, TIRM). On the other hand, it is hypointense and less evident in T1-weighted images. It becomes enhanced (hyperintense) after contrast administration. Histopathological studies confirmed that it is a result of bone inflammation (osteitis/osteomyelitis), i.e. replacememt of bone marrow fat by inflammatory infiltrates containing macrophages, T lymphocytes, B lymphocytes, plasma cells and osteoclasts. Bone marrow edema appears after a few weeks from occurrence of symptoms and therefore is considered an early marker of inflammation. It correlates with clinical assessment of disease activity and elevated markers of acute inflammatory phase, i.e. ESR and CRP. It is a reversible phenomenon and may become attenuated due to biological treatment. It is considered a “herald” of erosions, as the risk of their formation is 6-fold higher in sites where BME was previously noted

    We report neuroimaging findings of intracranial hemorrhage and cerebral edema in an infant with obtundation and seizures, initially suspected to be secondary to non-accidental trauma but finally attributed to hypernatremic dehydration. Neuroimaging findings due to hypernatremic dehydration have not been previously described in the radiologic literature. Hypernatremia should be included in the differential diagnosis of intracranial hemorrhage in the infant without evidence of nonaccidental trauma. (orig.). With 1 fig.

    Objective: To study the feasibility and efficiency of treatment in the patients with acute moderate and severe ischemic stroke with Neurotropin for its principle of inhibiting cerebral edema and repairing injured neurons. Methods: A randomized controlled trial with Neurotropin was performed in 50 patients admitted within 48h after an acute internal carotid artery infarction, Neurological deficits score ( Europe Stroke Scale-ESS ) <80 marks and the area of infarct and edema>2.25cm2. There were 31 patients in the Neurotropin group and 19 patients in the control group. Basic treatment was Troxerutin 250 mg intravenous drip per day for 21 days in two groups. Additionally, the patients in the Neurotropin group were intravenous injected 106 ampoule Neurotropin (3.6 unit per ampoule), divided into 11 days. We evaluated Neurological deficits score (ESS), ability of daily living (ADL)- Barthel Index, the size and average CT density of infarct and edema area on CT scan during different treatment stage and analyzed.them with statistics. Results: The percentage of improved patients (complete and partial recovery) reaches 64.5% in the Neurotropin group and 31.6% in the control group. The size of the infarct and edema area on CT scan is significantly reduced only in the Neurotropin group after treatment. The average range reduced is 28% on day 11 and 41.5% on day 21, and the average CT density in the Neurotropin group is more advanced than in the control group after onset. Conclusion: Neurotropin can be used as an effective therapy in acute ischemic stroke and ischemic cerebral edema.

    Diabetes mellitus is a chronic disease which has multiple effects on different end-organs, including the retina. In this paper, we discuss updates on diabetic macular edema (DME) and the management options. The underlying pathology of DME is the leakage of exudates from retinal microaneurysms, which trigger subsequent inflammatory reactions. Both clinical and imaging techniques are useful in diagnosing, classifying, and gauging the severity of DME. We performed a comprehensive literature sear...

    万兴丽; 曾力楠

    2012-01-01

    Objective To make an individualized administration scheme via evidence-based medicine methods, namely adding heparin into the total nutrient admixture (TNA) solution, so as to help a neonate to prevent the occlusion of peripherally inserted central catheter (PICC). Methods After carefully assessing the condition of neonate, this clinical issue was put forward in accordance with the PICO principles. Randomized controlled trials (RCTs) and systematic reviews on neonates' PICC occlusion were collected from The Cochrane Library, CCTR, DARE, NGC, MEDLINE (Ovid) and CBM from inception to 2011. The clinical intervention scheme was finally made after the assessment of the retrieved evidence and neonate's physiological condition. Results A total of 4 RCTs and 1 systematic review related to the issues were identified. The following scheme was finally made for the neonate through the assessment of the retrieved evidence and combination of intentions of the patient's family members: heparin (0.5 U/mL) was added into TNA to prevent PICC occlusion. During the application, blood routine test and blood coagulation were monitored, and the catheter opening time and extubation reason were recorded. Through the above treatment, the neonate successfully completed the treatment before extubation. The time of both PICC detaining and opening was 20 days in total, and there were no PICC occlusion, no catheter thrombosis, and no catheter related bloodstream infection. Moreover, no observation showed throm-bopenia and aggravated coagulation disorders resulted from heparin. Conclusion The evidence-based medicine method is an effective way to make reasonable heparin scheme for neonate, so as to prevent PICC occlusion, reduce catheter thrombosis, decrease risks of catheter related blood circulation infection, assure successful completion of treatment, and guarantee the safety of patients.%目的 借助循证医学方法为1例经外周静脉穿刺中心静脉导管(PICC)输注全合一静脉

  2. Management of upper airway edema caused by hereditary angioedema

    Directory of Open Access Journals (Sweden)

    Farkas Henriette

    2010-07-01

    Full Text Available Abstract Hereditary angioedema is a rare disorder with a genetic background involving mutations in the genes encoding C1-INH and of factor XII. Its etiology is unknown in a proportion of cases. Recurrent edema formation may involve the subcutis and the submucosa - the latter can produce obstruction in the upper airways and thereby lead to life-threatening asphyxia. This is the reason for the high, 30-to 50-per-cent mortality of undiagnosed or improperly managed cases. Airway obstruction can be prevented through early diagnosis, meaningful patient information, timely recognition of initial symptoms, state-of-the-art emergency therapy, and close monitoring of the patient. Prophylaxis can substantially mitigate the risk of upper airway edema and also improve the patients' quality of life. Notwithstanding the foregoing, any form of upper airway edema should be regarded as a potentially life-threatening condition. None of the currently available prophylactic modalities is capable of preventing UAE with absolute certainty.

    Peterson, B T; Petrini, M F; Hyde, R W; Schreiner, B F

    1978-05-01

    Pulmonary tissue volume (Vt) and pulmonary capillary blood flow (Qc) were measured in anesthetized dogs by analyzing end-expiratory concentrations of dimethyl ether (DME), acetylene (C2H2), and sulfur hexafluoride during a 30-s rebreathing maneuver. Vt was compared to the postmortem lung weight of control dogs and dogs with hemodynamic and nonhemodynamic (alloxan) pulmonary edema. Qc was compared to the cardiac output measured by dye dilution. A 100-ml increase in alveolar volume (VA) in the range of 1-2 liters resulted in a 9 +/- 3 ml increase in Vt. Vt measured at a VA of 1.9 liters measures 114 +/- 18% of the postmortem lung weight in 20 control dogs and in 6 dogs with moderate edema (lung weight smae mean values of Vt, but the reproducibility of a series of 3-7 measurements was greater with DME (coefficient of variation was 5% with DME and 8% C2H2). Qc measured 96 +/ 15% of the cardiac output during the rebreathing maneuver, but the maneuver caused a 4-40% fall in the cardiac output. These data show that Vt determined by rebreathing DME is between 86% and 135% of the lung weight in dogs with pulmonary edema until the lung weight is greater than 250% of the predicted value.

    Full Text Available We describe a case of 17 year-old male with a nasopharyngeal rhabdomyosarcoma who developed postobstructive pulmonary edema (POPE after removing the endotracheal tube following biopsy. He developed muffled voice, rhinorrhea, dysphagia, odynophagia, and difficulty breathing through nose and weight loss of 20 pounds in the preceding 2 months. A nasopharyngoscopy revealed a fleshy nasopharyngeal mass compressing the soft and hard palate. Head and neck MRI revealed a large mass in the nasopharynx extending into the bilateral choana and oropharynx. Biopsy of the mass was taken under general anesthesia with endotracheal intubation. Immediately after extubation he developed oxygen desaturation, which did not improve with bag mask ventilation with 100% of oxygen, but improved after a dose of succinylcholine. He was re-intubated and pink, frothy fluid was suctioned from the endotracheal tube. Chest radiograph (CXR was suggestive of an acute pulmonary edema. He improved with mechanical ventilation and intravenous furosemide. His pulmonary edema resolved over the next 24 h. POPE is a rare but serious complication associated with upper airway obstruction. The pathophysiology of POPE involves hemodynamic changes occurring in the lung and the heart during forceful inspiration against a closed airway due to an acute or chronic airway obstruction. This case illustrates the importance of considering the development of POPE with general anesthesia, laryngospasm and removal of endotracheal tube to make prompt diagnosis and to initiate appropriate management.

    2015-05-01

    Full Text Available INTRODUCTION: Hyperbilirubinemia is one of the most common causes of health problems, observed in 60% of term and 80% of preterm infants in the first week of life . Hyperbilirubinemia leads to neurotoxicity in severe condition. Some studies suggests that liberal use of oxytocin for inducing labour is one of the factor which lead to neonatal hyperbilirubinemia. OBJECTIVE: To compare the effect of oxytocin and neonatal bilirubin levels with spontaneous vaginal delivery . MATERIALS AND METHOD S : 100 full term parturients were selected for this study. The subjects were divided into two groups. 50 healthy babies of women who had oxytocin induced labour and 50 healthy babies of women with normal vaginal delivery following spontaneous onset of labour formed the control group. Neon atal serum bilirubin was measured on day 1, 3 and 5 after delivery. Bilirubin was measured by spectrophotometry. Data was analysed in ms excel sheet using spss 19.0v. Statistical analysis was done by using unpaired‘t’ test. RESULTS: There was significant i ncrease in bilirubin level in oxytocin induced group compared to control group on day 1 and 3. There was insignificant increase in bilirubin level in oxytocin induced group on day 5. However the level of serum bilirubin is within normal limits as bilirubin level normally rises on till 4 th day and decreases thereafter. CONCLUSION: Neonatal hyperbilirubinemia may be due to oxytocin administration by continues IV infusion which results in erythrocyte swell and rupture. Increase in bilirubin level in oxytocin i nduced group is within physiological limits

    Hemolysis can be an important cause of hyperbilirubinemia in premature and term neonates. It can result from genetic abnormalities intrinsic to or factors exogenous to normal to red blood cells (RBCs). Hemolysis can lead to a relatively rapid increase in total serum/plasma bilirubin, hyperbilirubinemia that is somewhat slow to fall with phototherapy, or hyperbilirubinemia that is likely to rebound after phototherapy. Laboratory methods for diagnosing hemolysis are more difficult to apply, or less conclusive, in preterm infants. Transfusion of donor RBCs can present a bilirubin load that must be metabolized. Genetic causes can be identified by next-generation sequencing panels. PMID:27235204

    Plain radiographs for infants in the neonatal intensive care unit are obtained using the portable X-ray equipment in order to evaluate the neonatal lungs and also to check the position of the tubes and catheters used for monitoring critically-ill neonates. Neonatal respiratory distress is caused by a variety of medical or surgical disease conditions. Clinical information about the gestational week, respiratory symptoms, and any events during delivery is essential for interpretation of the neonatal chest radiographs. Awareness of common chest abnormality in the prematurely born or term babies is also very important for chest evaluation in the newborn. Furthermore, knowledge about complications such as air leaks and bronchopulmonary dysplasia following treatment are required to accurately inform the clinicians. The purpose of this article was to briefly review radiographic findings of chest diseases in newborns that are relatively common in daily practice.

    Objective To determine whether VEGF plays a role in the development of peritumoral brain edema. Methods 50 meningioma patients and their VEGF expression were studied. We took a mono- clonal antibody from mouse to VEGF to stain the tumor cells, the vascular endothelial cells and the interstitial cells. The severity of brain edema was evaluated according to CT or MR scans by the following equation: edema index = Vtumor+edema/Vtumor. The relationship between VEGF expression and edema index was analyzed statisti- cally. Results VEGF was expressed in meningioma tumor cells, which is usually concentrated at the pe- ripheral sites of the tumor. There was a positive linear correlation between the expression and the brain edema index. Conclusion VEGF may play a role in the development of peritumoral brain edema in meningioma patient.

On presentation, her best-corrected VA (BCVA was 2/10 in the left eye and the intraocular pressure was 15 mmHg. Fundoscopy revealed cystoid macular edema, intraretinal hemorrhages, epiretinal membrane in the posterior pole, and residual tumor scar with exudative retinal detachment and hard exudates in the periphery of the superotemporal quadrant. A treatment with intravitreal injections of bevacizumab (Avastin® was recommended. The injections were performed on a six-weekly basis.Results: The central retinal thickness prior to the treatment was 458 μm. After the first intravitreal injection of bevacizumab, the retinal thickness at the centre of the fovea was reduced to 322 μm. After the third injection, the central retinal thickness was 359 μm and 18 months after presentation, it reduced to 334 μm. The BCVA increased to 3/10 after the intravitreal injections of bevacizumab and remained stable during the follow-up period. The intraocular pressure was within normal range during the follow-up period.Conclusion: Bevacizumab should be regarded as a treatment option for macular edema due to proton beam radiotherapy for choroidal melanoma. By reducing the central retinal thickness, intravitreal bevacizumab can improve VA or ameliorate further decline caused by radiation maculopathy.Keywords: bevacizumab (Avastin®, choroidal melanoma, macular edema, radiation retinopathy

    Full Text Available Background: Neonatal jaundice refers to yellow coloration of the skin and the sclera (whites of the eyes of newborn babies that result from the accumulation of bilirubin in the skin and mucous membranes. Because bilirubin is potentially toxic to the central nervous system. Genetic disorders of bilirubin conjugation, particularly the common Gilbert′s syndrome, can also contribute to neonatal hyperbilirubinemia. Objective: The aim of this study was to evaluate the lipid per-oxidation and antioxidant enzyme activities in patients with neonatal jaundice before and after phototherapy. Materials and Methods: The study includes 50 neonatal jaundice patients with average age 2-15 days. All patients of neonatal jaundice receiving phototherapy except feeding, cleaning. Subjects selected were from the patients attending Pediatrics Department. Plasma malondialdehyde (MDA, erythrocyte glutathione peroxidase (GPX, superoxide dismutase and catalase (CAT to monitor the bilirubin level. Results: The results show increased levels of bilirubin compared with controls (P < 0.001 shows the level of plasma MDA in control, before and after phototherapy. Represents the level of GPX was significantly increased in after the phototherapy group when compared with before phototherapy and control SPSS soft ware: (P < 0.001. Shows the reduced glutathione (GSH level in plasma was significantly decreased in the after phototherapy group when compared with before phototherapy and control (P < 0.001. And finally with ascorbic acid and CAT. Conclusion: It is evident from the study that increased oxidative stress in neonatal jaundice babies leads to decrease in the levels of antioxidants like GSH and ascorbic acid and disturb their metabolism, that weaken their ability to fight the growing stress. Intense oxidative stress and decreased antioxidants may contribute to neural cell death and alter the erythrocytomembrane structure processing in neonatal jaundice.

    Full Text Available Background and Aim: Stroke is one of the most important factors of mortality and disability in the world. Free radicals are produced following ischemic stroke and they play a central role in breaking the blood-brain barrier and  causing brain edema formation. The aim of the current study was to evaluate the effect of hydro- alcoholic extract of Origanum vulgare on brain edema and neurologic deficit in a rat stroke model. Materials and Methods: In thisexperimental study, 35 male Wistar rats were randomly divided into 5 equal groups.  The first  two groups (control and Sham received distilled water, while three treatment groups received oral Origanum vulgare extract for 30days (50,75and 100 mg/kgdaily, respectively.  Two hours after the last dose of Origanum vulgare extract,each main group underwent  a 60 min middle cerebral artery occlusion.  Then, the assessment of blood brain edema, and neurologic deficits analysis were done . Brain edema (brain water content was analyzed by One-Way ANOVA using LSD method and neurologic deficits analysis by means of Mann-Whitney U, and P<0.05 was taken as the significant level. Results: Origanum vulgare extract reduced brain edema in the experimental groups of 50 (82.49±0.47, 75 (80.89±0.63 and 100 mg/kg/day (80.80±0.66 compared to the control group (84.46±0.67. The neurologic deficit scores in the experimental groups of 75and 100mg/kg/day, compared with control group, but neurologic deficit scores did not affect the group receiving the dose 50 mg/kg. Conclusion:  The obtained data indicate that Origanum vulgar extract via reduction of brain edema and neurologic deficits scorescan have a protective effect on the stroke model.

    The inflammatory response induced by Bothrops lanceolatus venom (BLV) in the rat hind-paw was studied measuring paw edema. Non-heated BLV (75microg/paw) caused a marked paw edema accompanied by intense haemorrhage whereas heated venom (97 degrees C, 30s; 12.5-100microg/paw) produced a dose- and time-dependent non-haemorrhagic edema. The response with heated BLV was maximal within 15min disappearing over 24h. Heated venom was then routinely used at the dose of 75microg/paw. The prostacyclin analogue iloprost (0.1microg/paw) potentiated by 125% the venom-induced edema. The histamine H(1) receptor antagonist mepyramine (6mg/kg) or the serotonin/histamine receptor antagonist cyproheptadine (6mg/kg) partially inhibited BLV-induced edema whereas the combination of both compounds virtually abolished the edema. The lipoxygenase inhibitor BWA4C (10mg/kg), but not the cyclooxygenase inhibitor indomethacin (10mg/kg), significantly inhibited the edema (35% reduction; P<0.05). Dexamethasone (1mg/kg) also markedly (P<0.001) reduced venom-induced edema. The bradykinin B(2) receptor antagonist Hoe 140 (0.6mg/kg) reduced by 30% (P<0.05) the venom induced edema, whereas the angiotensin-converting enzyme inhibitor captopril (300microg/paw) potentiated by 42% (P<0.05) the edema. Bothrops lanceolatus antivenon (anti-BLV) reduced by 28% (P<0.05) the venom-induced edema while intravenous administration of antivenom failed to affect the edema. In conclusion, BLV-induced rat paw edema involves mast cell degranulation causing local release of histamine and serotonin, a phenomenon mediated mainly by kinins and lipoxygenase metabolites. Additionally, the use of a specific Bothrops lanceolatus antivenom, given subplantarily or intravenously, revealed to be little effective to prevent BLV-induced edema. PMID:11137542

    Radiological imaging is an important part of the evaluation and management of neonates with suspected anomalies of the gastrointestinal tract. Clinical presentation is often non-specific, commonly with abdominal distension and vomiting for which the underlying cause may or may not be clinically apparent. In a proportion of patients, the clinical assessment alone may suffice in providing the diagnosis and no further imaging is necessary. The reader must have an understanding of the normal radiographic appearances of the gastrointestinal tract in neonates and appreciate normal variants and differences to adults. In certain cases, the abdominal radiograph alone is diagnostic. In others, sonography and contrast studies are useful adjunct investigations and the indications for CT and MRI are few, but specific. Appropriate radiological investigation will help to establish the diagnosis and guide surgical intervention whilst also avoiding unnecessary radiation. Some of the conditions require transfer to specialist paediatric institutions for care. Thus, in some circumstances it is appropriate for imaging to be delayed and performed at the specialist centre with early referral often essential for the continued well being of the child.

    Full Text Available Neurogenic pulmonary edema is a serious and always life-threatening complication following several lesions of the central nervous system. We report an experiment with 58 Wistar-Hanover adult male rats. Two groups were formed: control (n=4 and experimental (n=54. The experimental group sustained acute midthoracic spinal cord injury by Fogarty’s balloon-compression technique containing 20µL of saline for 5, 15, 30 or 60 seconds. The rats were anesthetized by intraperitoneal (i.p. sodium pentobarbital (s.p. 60 mg/Kg. The quantitative neurological outcome was presented at 4, 24 and 48 hours from compression to characterize the injury graduation in different groups. Poor outcome occurred with 60 seconds of compression. Six animals died suddenly with pulmonary edema. Using the procedure to investigate the pulmonary edema during 60 seconds of compression, followed by decompression and time-course of 60 seconds, 20 rats were randomly asigned to one of the following groups: control (1, n=4, anesthetized by i.p. s.p., 60 mg/Kg but without compression and experimental (2, n=7, anesthetized by i.p. xylazine 10 mg/Kg and ketamine 75 mg/Kg and (3, n=9, anesthetized by i.p. s.p., 60 mg/Kg. The pulmonary index (100 x wet lung weight / body weight was 0.395 ± 0.018 in control group, rose to 0.499 ± 0.060 in group 2, and was 0.639 ± 0.14 in group 3. Histologic examination of the spinal cord showed parenchymal ruptures and acute hemorrhage. Comparison of the pulmonary index with morphometric evaluation of edema fluid-filled alveoli by light microscopy showed that relevant intra-alveolar edema occurred only for index values above 0.55. The results suggest that the pulmonary edema induced by spinal compression is of neurogenic nature and that the type of anesthesia used might be important for the genesis of lung edema.Edema pulmonar neurogênico é complicação séria e aumenta o risco de vida em pacientes com várias lesões do sistema nervoso central

    Esophageal dilatation (ED) in neonates is rare. In the present case, ED was detected in a chest radiograph following repair of congenital diaphragmatic hernia (CDH) in a term neonate. A roentgenographic swallow study on the seventh day of life demonstrated ED and a sub-diaphragmatic stomach. The infant thrived adequately on enteral feeding. A swallow study on the twentieth day of life showed a normal-width esophagus with gastroesophageal reflux and small hiatus hernia. The longstanding herniated stomach in the fetus apparently caused kinking, edema, and obstruction of the gastroesophageal junction. This led to a significant ED and concealment of gastroesophageal reflux. We aim to arouse awareness about the occurrence of ED with CDH, and about its benign course under conservative management.

    Full Text Available Cardiovascular malformations are the most common cause of congenital malformations, the diagnosis of which requires a close observation in the neonatal period. Early recognition of CHD is important in the neonatal period, as many of them may be fatal if undiagnosed and may require immediate intervention. The objectives of this study are to study the epidemiology of neonatal cardiac murmurs, to identify clinical characteristics which differentiate pathological murmur from functional murmurs and to assess the reliability of clinical evaluation in diagnosing CHD. Method of study included all neonates admitted to the NICU, postnatal ward, attending pediatric OPD or neonatal follow up clinic and were detected to have cardiac murmurs. It was a cross sectional study over a period of 16months. A clinical diagnosis was made based on history and clinical examination. Then Chest X-ray and ECG, Echocardiography was done in all neonates for confirmation of the diagnosis. These neonates were again examined daily till they were in hospital and during the follow-up visit at 6 weeks. The results of 70 neonates in this study conducted over a period of 24 months included the incidence of cardiac murmurs among intramural neonates which was 13.5 for 1000 live births. Most frequent symptom was fast breathing in 10(14.3% cases. VSD was the most common diagnosis clinically in 23 (33% babies. The most frequent Echo diagnosis was acyanotic complex congenital heart disease in 25(36% cases followed by 12(17% cases each of VSD and ASD respectively. Overall in our study 77.1% (54cases of the murmurs were diagnosed correctly and confirmed by Echocardiography The study concluded that it is possible to make clinical diagnosis in many cases of congenital heart diseases, the functional murmurs could be differentiated from those arising from structural heart disease and evaluation of the infants based only on murmurs, few congenital heart diseases can be missed.

    Full Text Available Aims: To evaluate the 1-month efficacy of intravitreal triamcinolone acetonide (TA in treating macular edema secondary to retinal vein occlusion (RVO that was refractory to intravitreal bevacizumab. Materials and Methods: This retrospective, observational study included 23 eyes from 23 patients with macular edema secondary to RVO. Macular edema that did not respond to two or more consecutive intravitreal bevacizumab injections was treated with intravitreal TA. Central foveal thickness (CFT and best-corrected visual acuity (BCVA were compared before and one month after TA injection. Results: Fifteen eyes were diagnosed with central RVO, and eight eyes were diagnosed with branch RVO. All patients were previously treated with 2.4 ± 0.6 intravitreal bevacizumab injections. The TA injection was performed, on average, 5.8 ± 1.4 weeks after the last bevacizumab injection. The CFT before TA injection was 516.6 ± 112.4 μm and significantly decreased to 402.3 ± 159.7 μm after TA therapy (P < 0.001. The logarithm of the minimal angle of resolution BCVA was 0.72 ± 0.34 before TA therapy and was not significantly improved by the treatment (0.67 ± 0.35, P = 0.119, despite a decrease in CFT. However, seven eyes (30.4% had a BCVA gain of one or more lines. Conclusions: Intravitreal TA therapy was beneficial in some patients with macular edema secondary to RVO that was refractory to intravitreal bevacizumab therapy. This study suggests that intravitreal TA should be considered as a treatment option for refractory macular edema.

  1. Neonate brain disorders

    International Nuclear Information System (INIS)

    Full text: Hypoxic-Ischemic insults in the brain of neonates constitute major cause of morbidity and mortality. A wide range of motor, sensory, and cognitive disabilities are observed in this population spanning from slight motor deficits, school difficulties and behavioral problems up to cerebral palsy and mental retardation. Pathologically involved areas characterized by high metabolic demands and therefore with enhanced vulnerability to any reduction or cessation of energy and oxygen supply. Watershed areas of the brain (vascular end zones and vascular border zones) are predominately affected in any adverse event. Radiologic and pathologic appearance of these lesions depends both on the severity of the insult and the maturity of the brain. The dominant pathology observed in preterm neonates is white matter lesions. There are three basic patterns of brain destruction in this population. Periventricular leukomalacia (PVL focal fPVL, diffuse dPVL), germinal matrix haemorrhage (GMH) associated with intraventricular haemorrhage (IVH), and parenchymal haemorrhage (PH). fPVL is characterized by focal necrosis of all cellular elements in the periventricular white matter, resulting in the formation of cysts, and dPVL is characterized by diffuse destruction of the premyelinating oligodendrocytes (pre-OLs) the precursors of mature oligodendroglia cells responsible for the formation of myelin in a later stage. GMH is located beneath germinal matrix layer surrounding the lateral ventricles and can extend into the ventricular system resulting thus to IVH. Finally, PH is located within the parenchyma adjacent to the ventricles and is believed to represent haemorrhagic infarcts following venous drainage compromise. In term or near-term neonates, the top-ographic pattern of injuries involves mainly gray matter structures. Most frequent predilection sites include the cerebral cortex (paracentral lobule, Rolandic area, visual cortex and hippocampus), basal ganglia, thalamus, and

    The purpose of this study was to assess the use of analgesic agents for invasive medical procedures in pediatric and neonatal intensive care units. The directors of 38 pediatric units and 31 neonatal units reported that analgesics were infrequently used for intravenous cannulation (10%), suprapubic bladder aspiration (8%), urethral catheterization (2%), or venipuncture (2%). Analgesics were used significantly more regularly in pediatric than in neonatal intensive care units for arterial line placement, bone marrow aspiration, central line placement, chest tube insertion, paracentesis, and lumbar puncture.

These 28 eyes were divided into two groups; group 1 eyes underwent macular grid laser and group 2 eyes underwent panretinal photocoagulation. Treatment was performed for macular edema or for iris or retinal neovascularization. Outcomes measured included best-corrected visual acuity (BCVA, efficacy of laser treatment, complications, duration of the procedure, and pain perception, which were noted in the charts for panretinal treatments.Results: Follow-up was 5.9 ± 2.6 months for group 1 and 5.9 ± 4.0 months for group 2. In group 1, 9/28 eyes required a second treatment for remaining edema. BCVA was stable or better in 66% (14/21 and average central foveal thickness on ocular coherence tomography improved in 71% (15/21. Time to completion for a number of laser patterns for grid photocoagulation was felt to be too long for completing the total pattern safely, although we have not noted any related complications. In group 2, the neovascularization regressed at least partially in 3/7 patients. Patient-reported pain perception was 3.6 on a scale of 1 to 10 for group 2. Occasional hemorrhages occurred secondary to irregular laser uptake at different spots in the patterns. We observed no visual outcome consequences because of these hemorrhages during follow-up.Conclusions: Retinal photocoagulation by the PASCAL® laser has comparable efficacy to historical results with conventional retinal photocoagulation in short

Esto permite estudiar los mecanismos subyacentes del edema pulmonar en humanos, sin la presencia de factores que presten a la confusión como enfermedades concomitantes. El EPA resulta de la conjunción de dos defectos mayores: acumulación de líquido en el espacio alveolar debido a una hipertensión pulmonar hipóxica exagerada, y alteración en la eliminación del mismo por un defecto en el transporte transepitelial alveolar de sodio. En esta revisión, describimos brevemente las características clínicas y revisaremos este novedoso concepto. Proveemos evidencia experimental de como la síntesis alterada de óxido nítrico y/o la disminución de su biodisponibilidad representan el defecto central que predispone a la vasoconstricción pulmonar hipóxica exagerada y a la acumulación de líquido en el espacio alveolar. Mostramos que la hipertensión pulmonar hipóxica exagerada, per se, no es suficiente para producir un EPA, y que una alteración en la eliminación del fluido del espacio alveolar representa un segundo mecanismo fisiopatológico importante.

    Full Text Available Pravin U Dugel,1,2 Francesco Bandello,3 Anat Loewenstein4 1Retinal Consultants of Arizona, Phoenix, AZ, 2Department of Ophthalmology, Keck School of Medicine, University of Southern California, Los Angeles, CA, USA; 3Department of Ophthalmology, University Vita-Salute Scientific Institute San Raffaele, Milan, Italy; 4Department of Ophthalmology, Tel Aviv Medical Center and Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv, Israel Abstract: Diabetic macular edema (DME resembles a chronic, low-grade inflammatory reaction, and is characterized by blood–retinal barrier (BRB breakdown and retinal capillary leakage. Corticosteroids are of therapeutic benefit because of their anti-inflammatory, antiangiogenic, and BRB-stabilizing properties. Delivery modes include periocular and intravitreal (via pars plana injection. To offset the short intravitreal half-life of corticosteroid solutions (~3 hours and the need for frequent intravitreal injections, sustained-release intravitreal corticosteroid implants have been developed. Dexamethasone intravitreal implant provides retinal drug delivery for ≤6 months and recently has been approved for use in the treatment of DME. Pooled findings (n=1,048 from two large-scale, randomized Phase III trials indicated that dexamethasone intravitreal implant (0.35 mg and 0.7 mg administered at ≥6-month intervals produced sustained improvements in best-corrected visual acuity (BCVA and macular edema. Significantly more patients showed a ≥15-letter gain in BCVA at 3 years with dexamethasone intravitreal implant 0.35 mg and 0.7 mg than with sham injection (18.4% and 22.2% vs 12.0%.

    Full Text Available Acute pulmonary edema (APE occurring after scorpion sting is the leading cause of death of the victims of scorpion envenomation. The APE origin is still questioned by physicians treating these patients. Based on echocardiographic study of 20 patients with severe envenomation treated in Ouargla Hospital resuscitation ward during the last four years, the APE etiology seems more likely cardiogenic, referring to cardiac symptoms confirmed by echocardiography although other mechanisms may also be involved. This hypothesis is further confirmed by the positive response of patients to the administration of dobutamine.

    Full Text Available We describe an incident of development of acute pulmonary edema after the device closure of a secundum atrial septal defect in a 52-year-old lady, which was treated with inotropes, diuretics and artificial ventilation. Possibility of acute left ventricular dysfunction should be considered after the defect closure in the middle-aged patients as the left ventricular compliance may be reduced due to increased elastic stiffness and diastolic dysfunction. Baseline left atrial pressure may be > 10 mmHg in these patients. Associated risk factors for the left ventricular dysfunction are a large Qp:Qs ratio, systemic hypertension, severe pulmonary hypertension and paroxysmal atrial fibrillation.

  11. Neonatal bartter syndrome

    International Nuclear Information System (INIS)

    A pre-term baby girl was born following a pregnancy complicated by severe polyhydramnios at a gestational age of 36 weeks. She was initially suffering from respiratory distress consistent with idiopathic respiratory distress syndrome, and altered electrolyte imbalance with hyponatremia, hypokalemia and hypochloremic metabolic alkalosis. However, during the third week of life when she had dehydration along with significant electrolyte imbalance, Bartter's syndrome was considered which was supported by findings of high renin and aldosterone levels. Treatment was done by correction of electrolytes and dehydration along with indomethacin. The drug was well tolerated. The infant showed correction of electrolyte imbalance. The features of this case suggest an extreme form of Bartter's syndrome presenting from the early days of life. The syndrome is reported because of it's rarity and alerts pediatricians to the antenatal and neonatal variant of Bartter's syndrome. (author)

  12. The neonate in distress

    International Nuclear Information System (INIS)

    Respiratory distress is a very common and yet non-specific symptom in neonates and young infants. It may be manifested clinically in many ways, including tachypnea, apnea, periodic respiratory, grunting, retractions, nasal flaring, and cyanosis. In many instances, the chest radiograph is diagnostic or at least suggestive of the diagnosis. This fact is important in determining surgical or medical conditions that require emergency therapy. Even if the chest film is normal, valuable information can be gained. This initial normal radiograph can be used as a baseline film in the face of further developing symptoms which, likewise, may have developing radiographic findings. In any event, the chest radiograph gives the clinician ''direction'' in his or her search for the cause of the patient's respiratory distress

    2008-01-01

    BACKGROUND: Recent studies have demonstrated that tumor necrosis factor-like weak inducer of apoptosis (TWEAK) participates in brain edema. However, it is unclear whether blood-brain barrier (BBB) disruption is associated with TWEAK during the process of brain edema OBJECTIVE: To investigate the effects of TWEAK on BBB permeability in brain edema.DESIGN, TIME AND SETTING: An immunohistochemical observation, randomized, controlled animal experiment was pertbrmed at the Laboratory of Neurosurgical Anatomy, Xiangya Medical College, Central South University & Central Laboratory, Third Xiangya Hospital, Central South University between January 2006 and December 2007.MATERIALS: A total of 48 adult Wistar rats were randomly divided into three groups: normal control (n =8), sham-operated (n = 8), and ischemia/reperfusion (n = 32). Rats from the ischemia/reperfusion group were randomly assigned to four subgroups according to different time points, i.e., 2 hours of ischemia followed by 6 hours (n = 8), 12 hours {n = 8), 1 day (n = 8), or 12 days (n = 8) of reperfusion.METHODS: Focal cerebral ischemia/reperfusion injury was induced by middle cerebral artery occlusion (MCAO) using the suture method in rats from the ischemia/reperfusion group. Thread was introduced at a depth of 17-19 mm. Rats in the sham-operated group were subjected to experimental procedures similar to the ischemia/reperfusion group; however, the introducing depth of thread was 10 mm. The normal control group was not given any intervention.MAIN OUTCOME MEASURES: TWEAK expression was examined by immunohistochemistry; brain water content on the ischemic side was calculated as the ratio of dry to wet tissue weight; BBB permeability was measured by Evans blue extravasation.RESULTS: A total of eight rats died prior to and after surgery and an additional eight rats were randomly entered into the study. Thus 48 rats were included in the final analysis. In the ischemia/reperfusion group,TWEAK-positive cells were

    Background To secure pH homeostasis, the central respiratory network must permanently adapt its rhythmic motor drive to environment and behaviour. In neonates, it is commonly admitted that the retrotrapezoid/parafacial respiratory group of neurons of the ventral medulla plays the primary role in the respiratory response to acidosis, although the serotonergic system may also contribute to this response.

  16. Neonatal lupus syndromes.

    Buyon, J P; Rupel, A; Clancy, R M

    2004-01-01

    The neonatal lupus syndromes (NLS), while quite rare, carry significant mortality and morbidity in cases of cardiac manifestations. Although anti-SSA/Ro-SSB/La antibodies are detected in > 85% of mothers whose fetuses are identified with congenital heart block (CHB) in a structurally normal heart, when clinicians applied this testing to their pregnant patients, the risk for a woman with the candidate antibodies to have a child with CHB was at or below 1 in 50. While the precise pathogenic mechanism of antibody-mediated injury remains unknown, it is clear that the antibodies alone are insufficient to cause disease and fetal factors are likely contributory. In vivo and in vitro evidence supports a pathologic cascade involving apoptosis of cardiocytes, surface translocation of Ro and La antigens, binding of maternal autoantibodies, secretion of profibrosing factors (e.g., TGFbeta) from the scavenging macrophages and modulation of cardiac fibroblasts to a myofibroflast scarring phenotype. The spectrum of cardiac abnormalities continues to expand, with varying degrees of block identified in utero and reports of late onset cardiomyopathy (some of which display endocardial fibroelastosis). Moreover, there is now clear documentation that incomplete blocks (including those improving in utero with dexamethasone) can progress postnatally, despite the clearance of the maternal antibodies from the neonatal circulation. Better echocardiographic measurements which identify first degree block in utero may be the optimal means of approaching pregnant women at risk. Prophylactic therapies, including treatment with intravenous immunoglobulin, await larger trials. In order to achieve advances at both the bench and bedside, national research registries established in the US and Canada are critical.

    2016-01-01

    Patient: Female, 63 Final Diagnosis: Drug-induced hyponatremic encephalopathy Symptoms: Seizures • coma Medication: Hypertonic 3% saline infusion Clinical Procedure: — Specialty: Internal Medicine Objective: Unusual clinical course Background: Drug-induced hyponatremia characteristically presents with subtle psychomotor symptoms due to its slow onset, which permits compensatory volume adjustment to hypo-osmolality in the central nervous system. Due mainly to the syndrome of inappropriate antidiuretic hormone secretion (SIADH), this condition readily resolves following discontinuation of the responsible pharmacological agent. Here, we present an unusual case of life-threatening encephalopathy due to adverse drug-related effects, in which a rapid clinical response facilitated emergent treatment to avert life-threatening acute cerebral edema. Case Report: A 63-year-old woman with refractory depression was admitted for inpatient psychiatric care with a normal physical examination and laboratory values, including a serum sodium [Na+] of 144 mEq/L. She had a grand mal seizure and became unresponsive on the fourth day of treatment with the dual serotonin and norepinephrine reuptake inhibitor [SNRI] duloxetine while being continued on a thiazide-containing diuretic for a hypertensive disorder. Emergent infusion of intravenous hypertonic (3%) saline was initiated after determination of a serum sodium [Na+] of 103 mEq/L with a urine osmolality of 314 mOsm/kg H20 and urine [Na+] of 12 mEq/L. Correction of hyposmolality in accordance with current guidelines resulted in progressive improvement over several days, and she returned to her baseline mental status. Conclusions: Seizures with life-threatening hyponatremic encephalopathy in this case likely resulted from co-occurring SIADH and sodium depletion due to duloxetine and hydrochlorothiazide, respectively. A rapid clinical response expedited diagnosis and emergent treatment to reverse life-threatening acute cerebral edema

    Neurogenic pulmonary edema (NPE) is occasionally observed in patients with traumatic brain injury (TBI); however, this condition is often underappreciated. NPE is frequently misdiagnosed due to its atypical clinical performance, thus delaying appropriate treatment. A comprehensive management protocol of NPE in patients with TBI has yet to be established. The current study reported the case of a 67-year-old man with severe TBI who was transferred to our intensive care unit (ICU). On day 7 after hospitalization, the patient suddenly suffered tachypnea, tachycardia, systemic hypertension and hypoxemia during lumbar cistern drainage. Intravenous diuretics, tranquilizer and glucocorticoid were administered due to suspected left heart failure attack. Chest radiography examination supported the diagnosis of pulmonary edema; however, hypotension and hypovolemia were subsequently observed. Pulse index continuous cardiac output (PiCCO) hemodynamic monitoring and bedside echocardiography were performed, which excluded the diagnosis of cardiac pulmonary edema, and thus the diagnosis of NPE was confirmed. Goal-directed therapy by dynamic PiCCO monitoring was then implemented. In addition, levosimendan, an inotropic agent, was introduced to improve cardiac output. The patient had complete recovered from pulmonary edema and regained consciousness on day 11 of hospitalization. The current case demonstrated that PiCCO monitoring may serve a central role in the integrated management of NPE in patients with TBI. Levosimendan may be a potential medicine in treating cardiac dysfunction, along with its benefit from improving neurological function in NPE patients. PMID:27698733

  20. Neonatal euthanasia: The Groningen Protocol.

    2014-11-01

    For the past thirty years, voluntary euthanasia and physician-assisted suicide of adult patients have been common practice in the Netherlands. Neonatal euthanasia was recently legalized in the Netherlands and the Groningen Protocol (GP) was developed to regulate the practice. Supporters claim compliance with the GP criteria makes neonatal euthanasia ethically permissible. An examination of the criteria used by the Protocol to justify the euthanasia of seriously ill neonates reveals the criteria are not based on firm moral principles. The taking of the life of a seriously ill person is not the solution to the pain and suffering of the dying process. It is the role of the medical professional to care for the ailing patient with love and compassion, always preserving the person's dignity. Neonatal euthanasia is not ethically permissible.

    That rotavirus infection can cause neurological symptoms in young children has been well established. However, it is surprising why rotavirus infection has been overlooked as a cause of neonatal seizures for many years, despite significant research interest in neonatal rotavirus infection. Neonates are the age group most vulnerable to seizures, which are typically attributed to a wide range of causes. By contrast, because rotavirus infection is usually asymptomatic, it has been difficult to identify an association between this virus and neonatal seizures. The conventional wisdom has been that, although neonates are commonly infected with rotavirus, neurological complications are rare in this age. However, recent studies using diffusion-weighted imaging (DWI) have suggested a connection between rotavirus infection and neonatal seizures and that rotavirus infection can induce diffuse white matter injury without direct invasion of the central nervous system. The clinical features of white matter injury in rotavirus-infected neonates include the onset of seizures at days 4-6 of life in apparently healthy term infants. The recent findings seem to contradict the conventional wisdom. However, white matter injury might not be a completely new aspect of rotavirus infection in neonates, considering the forgotten clinical entity of neonatal seizures, 'fifth day fits'. With increased use of DWI in neonatal seizures, we are just starting to understand connection between viral infection and white matter injury in neonates. In this review, we discuss the historical aspects of rotavirus infection and neonatal seizures. We also present the clinical features of white matter injury in neonatal rotavirus infection.

    2016-09-01

    Non-penetrating or mild traumatic brain injury (mTBI) is commonly experienced in accidents, the battlefield and in full-contact sports. Astrocyte cellular edema is one of the major factors that leads to high morbidity post-mTBI. Various studies have reported an upregulation of aquaporin-4 (AQP4), a water channel protein, following brain injury. AZA is an antiepileptic drug that has been shown to inhibit AQP4 expression and in this study we investigate the drug as a therapeutic to mitigate the extent of mTBI induced cellular edema. We hypothesized that mTBI-mediated astrocyte dysfunction, initiated by increased intracellular volume, could be reduced when treated with AZA. We tested our hypothesis in a three-dimensional in vitro astrocyte model of mTBI. Samples were subject to no stretch (control) or one high-speed stretch (mTBI) injury. AQP4 expression was significantly increased 24 hours after mTBI. mTBI resulted in a significant increase in the cell swelling within 30 min of mTBI, which was significantly reduced in the presence of AZA. Cell death and expression of S100B was significantly reduced when AZA was added shortly before mTBI stretch. Overall, our data point to occurrence of astrocyte swelling immediately following mTBI, and AZA as a promising treatment to mitigate downstream cellular mortality.

    Full Text Available Diabetes mellitus is a chronic disease which has multiple effects on different end-organs, including the retina. In this paper, we discuss updates on diabetic macular edema (DME and the management options. The underlying pathology of DME is the leakage of exudates from retinal microaneurysms, which trigger subsequent inflammatory reactions. Both clinical and imaging techniques are useful in diagnosing, classifying, and gauging the severity of DME. We performed a comprehensive literature search using the keywords “diabetes,” “macula edema,” “epidemiology,” “pathogenesis,” “optical coherence tomography,” “intravitreal injections,” “systemic treatment,” “hypertension,” “hyperlipidemia,” “anemia,” and “renal disease” and collated a total of 47 relevant articles published in English language. The main modalities of treatment currently in use comprise laser photocoagulation, intravitreal pharmacological and selected systemic pharmacological options. In addition, we mention some novel therapies that show promise in treating DME. We also review systemic factors associated with exacerbation or improvement in DME.

    Multiple potentially injurious agents are present in smoke but the importance of each of these agents in producing lung injury as well as the mechanisms by which the lung injury is produced are unknown. In order to study smoke inhalation injury, we developed a synthetic smoke composed of a carrier of hot carbon particles of known size to which a single known common toxic agent in smoke, in this case HCI, could be added. We then exposed rats to the smoke, assayed their blood for the metabolites of thromboxane and prostacyclin, and intervened shortly after smoke with the cyclooxygenase inhibitors indomethacin or ibuprofen to see if the resulting lung injury could be prevented. Smoke exposure produced mild pulmonary edema after 6 h with a wet-to-dry weight ratio of 5.6 +/- 0.2 SEM (n = 11) compared with the non-smoke-exposed control animals with a wet-to-dry weight ratio of 4.3 +/- 0.2 (n = 12), p less than 0.001. Thromboxane B, and 6-keto-prostaglandin F1 alpha rose to 1660 +/- 250 pg/ml (p less than 0.01) and to 600 +/- 100 pg/ml (p greater than 0.1), respectively, in the smoke-injured animals compared with 770 +/- 150 pg/ml and 400 +/- 100 pg/ml in the non-smoke-exposed control animals. Indomethacin (n = 11) blocked the increase in both thromboxane and prostacyclin metabolites but failed to prevent lung edema.

    Science.gov (United States)

    Blumberg, H; Griesser, H J; Hornyak, M

    1992-01-01

    The present paper describes various mechanisms, possibly being involved in the development of the posttraumatic, distally generalized edema. New ideas point to a special importance of the sympathetic vasoconstrictor system for this clinical phenomenon, since this system could induce an enhanced venoconstriction at the exit of the capillary bed, which would result in an edema producing diminished venous return. Since the distally generalized edema is an initially and very commonly occurring symptom of reflex sympathetic dystrophy (M. Sudeck), the observation of such an edema should lead one to look for further symptoms of this disorder, especially for the typical triad of autonomic (sympathetic), motor, and sensory disturbances.

    Perianeurysmal edema and aneurysm wall enhancement are previously described phenomenon after coil embolization attributed to inflammatory reaction. We aimed to demonstrate the prevalence and natural course of these phenomena in unruptured aneurysms after endovascular treatment and to identify factors that contributed to their development. We performed a retrospective analysis of consecutively treated unruptured aneurysms between January 2000 and December 2011. The presence and evolution of wall enhancement and perianeurysmal edema on MRI after endovascular treatment were analyzed. Variable factors were compared among aneurysms with and without edema. One hundred thirty-two unruptured aneurysms in 124 patients underwent endovascular treatment. Eighty-five (64.4 %) aneurysms had wall enhancement, and 9 (6.8 %) aneurysms had perianeurysmal brain edema. Wall enhancement tends to persist for years with two patterns identified. Larger aneurysms and brain-embedded aneurysms were significantly associated with wall enhancement. In all edema cases, the aneurysms were embedded within the brain and had wall enhancement. Progressive thickening of wall enhancement was significantly associated with edema. Edema can be symptomatic when in eloquent brain and stabilizes or resolves over the years. Our study demonstrates the prevalence and some appreciation of the natural history of aneurysmal wall enhancement and perianeurysmal brain edema following endovascular treatment of unruptured aneurysms. Aneurysmal wall enhancement is a common phenomenon while perianeurysmal edema is rare. These phenomena are likely related to the presence of inflammatory reaction near the aneurysmal wall. Both phenomena are usually asymptomatic and self-limited, and prophylactic treatment is not recommended. (orig.)

    For the first time, we have implemented photoacoustic tomography (PAT) to image the water content of an edema in vivo. We produced and imaged a cold-induced cerebral edema transcranially, then obtained blood vessel and water accumulation images at 610 and 975 nm, respectively. We tracked the changes at 12, 24, and 36 h after the cold injury. The blood volume decreased after the cold injury, and the maximum area of edema was observed 24 h after the cold injury. We validated PAT of the water content of the edema through magnetic Resonance Imaging and the water spectrum from the spectrophotometric measurement.

    Dengue is an infectious disease caused by a flavivirus, with four serotypes, transmitted by the mosquito Aedes aegypti. In Mexico it is a public health problem, especially in the region of central and southeast of the country. The disease can be asymptomatic or present serious forms and even death. It is confirmed by detection of the NS1 Antigen; IgM antibodies, polymerase chain reaction and virus isolation. The vertical transmission to de newborn has been little studied. 7 cases in neonates from November to December 2011 are reported. All patients were male, obtained by caesarean section between 34 and 40 weeks of gestation, whose mothers were enrolled with fever and symptoms associated with dengue disease and serology positive for dengue. Six with positive AgNS1 and one positive IgM; one mother died. All the newborns had positive serology for dengue, 4 with positive AgNS1 and 3 positive IgM. The clinical features of the newborn ranged from asymptomatic to one serious dengue fever, shock and hemorrhage.

    BACKGROUND: Routine care for chylothorax in neonate includes either conservative or surgical approaches. Octreotide, a somatostatin analogue, has been used for the management of patients with refractory chylothorax not responding to conservative management. OBJECTIVES: To assess the efficacy and safety of octreotide in the treatment of chylothorax in neonates. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE and EMBASE (to March 7, 2010). We assessed the reference lists of identified trials and abstracts from the annual meetings of the Pediatric Academic Societies published in Pediatric Research (2002 to 2009) without language restrictions. SELECTION CRITERIA: We planned to include randomised or quasi-randomised controlled trials of octreotide in the treatment of congenital or acquired chylothorax in term or preterm neonates, with any dose, duration or route of administration. DATA COLLECTION AND ANALYSIS: Data on primary (amount of fluid drainage, respiratory support, mortality) and secondary outcomes (side effects) were planned to be collected and analysed using mean difference, relative risk and risk difference with 95% confidence intervals. MAIN RESULTS: No randomised controlled trials were identified. Nineteen case reports of 20 neonates with chylothorax in whom octreotide was used either subcutaneously or intravenously were identified. Fourteen case reports described successful use (resolution of chylothorax), four reported failure (no resolution) and one reported equivocal results following use of octreotide. The timing of initiation, dose, duration and frequency of doses varied markedly. Gastrointestinal intolerance and clinical presentations suggestive of necrotizing enterocolitis and transient hypothyroidism were reported as side effects. AUTHORS\\' CONCLUSIONS: No practice recommendation can be made based on the evidence identified in this review. A prospective registry of

  20. Concealment of neonatal cerebral infarction on MRI by normal brain water

    International Nuclear Information System (INIS)

    Magnetic resonance imaging (MRI) is highly sensitive in detecting cerebral infarction in adults, both in the acute and chronic stages. Cytotoxic and vasogenic edema produce an increase in the water content of acutely ischemic brain, resulting in good tissue contrast from adjacent normal brain on spin density, T1 and T2 weighted MR images. Gliosis and other chronic brain changes are well seen in later stages. We recently encountered a case of remote cerebral infarction in an infant, however, which was not evident on the initial MR examination at 7 weeks of age but which was clearly seen on a follow-up scan at 9 1/2 months. Our contention is that the infarct was masked by the known increased water content of the neonatal brain, which results in lengthened spin density and relaxation times; edema and gliosis may thus be obscured. This age-related concealment of ischemic brain changes on MR has not to our knowledge been reported, and we present this case as a caveat in the detection of cerebral infarction in neonates. (orig.)

  1. Dexamethasone intravitreal implant in the treatment of diabetic macular edema.

    Diabetic macular edema (DME) resembles a chronic, low-grade inflammatory reaction, and is characterized by blood-retinal barrier (BRB) breakdown and retinal capillary leakage. Corticosteroids are of therapeutic benefit because of their anti-inflammatory, antiangiogenic, and BRB-stabilizing properties. Delivery modes include periocular and intravitreal (via pars plana) injection. To offset the short intravitreal half-life of corticosteroid solutions (~3 hours) and the need for frequent intravitreal injections, sustained-release intravitreal corticosteroid implants have been developed. Dexamethasone intravitreal implant provides retinal drug delivery for ≤6 months and recently has been approved for use in the treatment of DME. Pooled findings (n=1,048) from two large-scale, randomized Phase III trials indicated that dexamethasone intravitreal implant (0.35 mg and 0.7 mg) administered at ≥6-month intervals produced sustained improvements in best-corrected visual acuity (BCVA) and macular edema. Significantly more patients showed a ≥15-letter gain in BCVA at 3 years with dexamethasone intravitreal implant 0.35 mg and 0.7 mg than with sham injection (18.4% and 22.2% vs 12.0%). Anatomical assessments showed rapid and sustained reductions in macular edema and slowing of retinopathy progression. Phase II study findings suggest that dexamethasone intravitreal implant is effective in focal, cystoid, and diffuse DME, in vitrectomized eyes, and in combination with laser therapy. Ocular complications of dexamethasone intravitreal implant in Phase III trials included cataract-related events (66.0% in phakic patients), intraocular pressure elevation ≥25 mmHg (29.7%), conjunctival hemorrhage (23.5%), vitreous hemorrhage (10.0%), macular fibrosis (8.3%), conjunctival hyperemia (7.2%), eye pain (6.1%), vitreous detachment (5.8%), and dry eye (5.8%); injection-related complications (eg, retinal tear/detachment, vitreous loss, endophthalmitis) were infrequent (implant offers a

    Previous investigations suggest that ataxia is common and often one of the most reliable warning signs of high altitude cerebral edema(HACE).The aim of this study was to investigate the diagnostic role of ataxia in acute mountain sickness (AMS) and HACE among mountain rescuers on the quake areas,and in approaching the relation between AMS and HACE.After the earthquake on April 14,2010,approximately 24080 lowland rescuers were rapidly transported from sea level or lowlands to the mountainous rescue sites at 3750 ~ 4568 m,and extremely hardly worked for an emergency treatment after arrival.Assessments of acute altitude illness on the quake areas were using the Lake Louise Scoring System.73 % of the rescuers were found to be developed AMS.The incidence of high altitude pulmonary edema(HAPE) and HACE was 0.73 % and 0.26 %,respectively,on the second to third day at altitude.Ataxia sign was measured by simple tests of coordination including a modified Romberg test.The clinical features of 62 patients with HACE were analyzed.It was found that the most frequent,serious neurological symptoms and signs were altered mental status(50/62,80.6 %)and truncal ataxia (47/62,75.8 %).Mental status change was rated slightly higher than ataxia,but ataxia occurred earlier than mental status change and other symptoms.The earliest sign of ataxia was a vague unsteadiness of gait,which may be present alone in association with or without AMS.Advanced ataxia was correlated with the AMS scores,but mild ataxia did not correlate with AMS scores at altitudes of 3750~4568 m.Of them,14 patients were further examined by computerized tomographic scanning of the brain and cerebral magnetic resonance imagines were examined in another 15 cases.These imaging studies indicated that the presence of the cerebral edema was in 97 % of cases who were clinically diagnosed as HACE (28/29).Ataxia seems to be a reliable sign of advanced AMS or HACE,so does altered mental status.

    Full Text Available Neonatal tetanus (NNT has been secondary in the whole world in the death list of diseases which can be protected by the help of vaccine. It’s an important community health problem in the less-developed countries in which pre-birth care services are limited, assisting a mother at childbirth by uneducated people in dirty atmosphere and the immunity against tetanus is not enough. Studies have shown that minor part of the cases have been expressed in most of the countries. Because of that NNT have been called as “silent/invisible murderer”. In Turkey, in the year of 2003 it has been seen 15 cases, and 12 of them have been resulted in death. The methods which will be applied to carry out the elimination of NNT are; the vaccination of pregnant women with at least two doses tetanus toxoid and providing clean birth conditions for all of the pregnant women. However, in Turkey the proportion of the women who have two doses of tetanus vaccine is 41%. To eliminate NNT in our country, all the pregnant women must be attained, the ones who are attained must be presented with qualified pre-birth care service which also includes tetanus immunity and the births must be carried out under healty conditions. As smallpox and polio eradication, NNT elimination will also be accomplished by self-sacrificing works of personnel in primary health care. [TAF Prev Med Bull 2006; 5(3.000: 229-233

    The authors compared axillary skin temperatures (AT) measured with an infrared (IR) thermometer (Lightouch Neonate, Exergen Corp) with rectal temperatures (RT) in 16 newly born term infants under radiant warmers (RW) and in cribs. Twelve stable, growing premature infants in incubators were also studied. This new device may be useful because of safety and rapid results (1 second), but clinical accuracy is unknown. For term infants, mean (SD) RT-AT difference was 0.1 (0.48) degree C under RW and 0.25 (0.17) degree C 2 hours later in cribs. For premature infants in incubators the mean RT-AT difference was 0.09 (0.16) degree C. Axillary temperatures measured by IR thermometer approximate RT for newly born term infants in cribs and stable premature infants in incubators. For newly born term infants under RW, RT-AT differences vary more widely, limiting clinical usefulness in this setting. The device, the unique age of this population, and the RW environment may play a role. PMID:9924640

    Full Text Available Abstract Background Peritumoral edema is a characteristic feature of malignant glioma related to the extent of neovascularisation and to vascular endothelial growth factor (VEGF expression. The extent of peritumoral edema and VEGF expression may be prognostic for patients with glioblastoma. As older age is a negative prognostic marker and as VEGF expression is reported to be increased in primary glioblastoma of older patients, age-related differences in the extent of peritumoral edema have been assessed. Methods In a retrospective, single-center study, preoperative magnetic resonance imaging (MRI scans of steroid-naïve patients (n = 122 of all age groups were analysed. Patients with clinically suspected, radiologically likely or known evidence of secondary glioblastoma were not included. Extent of brain edema was determined in a metric quantitative fashion and in a categorical fashion in relation to tumor size. Analysis was done group-wise related to age. Additionally, tumor size, degree of necrosis, superficial or deep location of tumor and anatomic localization in the brain were recorded. Results The extent of peritumoral edema in patients >65 years (ys was not different from the edema extent in patients ≤ 65 ys (p = 0.261. The same was true if age groups ≤ 55 ys and ≥ 70 ys were compared (p = 0.308. However, extent of necrosis (p = 0.023, deep tumor localization (p = 0.02 and frontal localisation (p = 0.016 of the tumor were associated with the extent of edema. Tumor size was not linearly correlated to edema extent (Pearson F = 0.094, p = 0.303 but correlated to degree of necrosis (F = 0.355, p Conclusion Age at diagnosis does not determine degree of peritumoral edema, and tumor localization in the white matter is associated with greater extent of edema. The area of necrosis is reflective of volume of edema. In summary, the radiographic appearance of a glioblastoma at diagnosis does not reflect biology in the elderly patient.

    Amiodarone is a highly effective antiarrhythmic drug. Its long-term use may, however, lead to several adverse effects, with pulmonary toxicity being the most serious. The article presents the case of a 78-year-old woman with a history of cardiac surgery, who after 2 years of amiodarone therapy for prophylactic treatment of atrial fibrillation developed amiodarone pneumonitis mimicking an acute pulmonary edema. The patient failed to respond to diuretic therapy and several courses of anti-infective therapy. Differential diagnosis of different causes of pulmonary infiltrates did not demonstrate any other abnormality. Lung biopsy findings were consistent with the diagnosis of amiodarone pneumonitis. Given the widespread use of amiodarone as an antiarrhythmic agent, pneumologists and cardiologists should consider this important adverse effect as a differential diagnosis of pulmonary distress refractory to therapy in all patients treated with amiodarone who present with respiratory symptoms and pneumonia-like illness.

  7. Pulmonary edema and lung injury after severe laryngospasm

    International Nuclear Information System (INIS)

    A young male with no pre-operative medical illness underwent corrective surgery for a deviated nasal septum under general anesthesia. At the end of surgery, patient was extubated but went into severe laryngospasm that did not improve with gentle Intermittent Positive Pressure Ventilation (IPPV) and small dose of Suxamethonium. As the situation worsened and patient developed severe bradycardia and de-saturation, re-intubation was done that revealed pink froth in the endotracheal tube. His portable chest X-ray was suggestive of non-cardiogenic pulmonary edema. With an overnight supportive treatment, using mechanical ventilation with Positive End- Expiratory Pressure (PEEP), morphine infusion and frusemide, patient improved and was subsequently weaned off from ventilator.

    Purpose: To investigate the macular changes induced by laser in situ keratomileusisc(LASIK) procedure.Methods: Optical Coherence Tomography(OCT) was used to examine 27 eyes of 15LASIK patients before surgery, and 1 day, 1 week, 1 month after surgery.Results: The mean thick iness of neuroepithelial layer of macula was (195±24)microns, ( 178 ± 16) microns 1 day and 1 month after surgery, respectively, while thebaseline was (174 ± 12)microns. The increase in macular neuroepithelial thickness wascorrelated with the degree of myopia, but not with the duration of suction or thepostoperative BCVA.Conclusion: Mild macular edema is common in the first month following LASIK,especially in high myopia. However, no association with loss of BCVA has beenestablished.

    Objective: To review the pathophysiology and study the diagnosis and clinical management of neurogenic pulmonary edema (NPE). Methods: The data of 5 patients who developed NPE after head injury treated in our hospital form December 1995 to May 2003 were collected and analyzed.Results: The patients developed dyspnea and respiratory failure 2-8 hours after neurologic event. Four of the 5 patients presented with pink frothy sputum. Chest radiography showed bilateral diffuse infiltrations in all the 5 patients. After supportive measures such as oxygen support and pharmacologic therapy, 4 patients recovered in 72 hours and one patient died. Conclusions: The pathophysiologic mechanisms of NPE is unclear. In acute respiratory failure following head injury, NPE must be given much attention and timely and effective measures should be taken.

    Advances in medical and surgical care of the high-risk neonate have led to increased survival. A significant number of these neonates suffer from neurodevelopmental delays and failure in school. The focus of clinical research has shifted to understanding events contributing to neurological morbidity in these patients. Assessing changes in cerebral oxygenation and regulation of cerebral blood flow (CBF) is important in evaluating the status of the central nervous system. Traditional CBF imaging methods fail for both ethical and logistical reasons. Optical near infrared spectroscopy (NIRS) is increasingly being used for bedside monitoring of cerebral oxygenation and blood volume in both very low birth weight infants and neonates with congenital heart disease. Although trends in CBF may be inferred from changes in cerebral oxygenation and/or blood volume, NIRS does not allow a direct measure of CBF in these populations. Two relatively new modalities, arterial spin-labeled perfusion magnetic resonance imaging and optical diffuse correlation spectroscopy, provide direct, noninvasive measures of cerebral perfusion suitable for the high-risk neonates. Herein we discuss the instrumentation, applications, and limitations of these noninvasive imaging techniques for measuring and/or monitoring CBF. PMID:20109972

    Full Text Available BACKGROUND : Neonates receiving phototherapy have side effects like hypocalcemia and electrolyte changes. Our study is hereby intended to study the serum sodium changes due to phototherapy. AIMS : To evaluate the serum sodium changes in neonates receiving phototherapy f or neonatal hyperbilirubinemia. SETTINGS AND DESIGN : A prospective hospital based comparative study conducted on neonates admitted in the Neonatal Intensive Care Unit receiving phototherapy. METHODS AND MATERIAL : A predesigned proforma has aided the enroll ment of 252 newborns into the study. Serum bilirubin and serum sodium were determined before and after termination of phototherapy. The first samples were considered as controls. A comparative study was made between before and after phototherapy groups to determine the incidence of serum sodium imbalances. STATISTICAL ANALYSIS USED : Proportions will be compared using chi - square test. All data of various groups will be tabulated and statistically analyzed using suitable statistical tests (Student's t test. RESULTS : Male to Female ratio was 1.45 : 1. Incidence of low birth weight babies was 23% and preterm was 20.2%. Mean birth weight and gestational age was 2.84±0.51 kg and 38.44±1.98 wks respectively. Mean duration of phototherapy was 37.65±11.06 hrs. The incidence of hyponatremia post phototherapy found to be 6% which was more in low birth weight (LBW babies (17.2% , p48 hrs (p<0.001. Even the decline in mean serum sodium values after phototherapy found to be statistically significant. CONCLUSION : Our study shows that neonates u nder phototherapy are at higher risk of hyponatremia. This risk is greater in premature and LBW babies and hence this group of babies should be closely monitored for changes in serum sodium and should be managed accordingly.

    Full Text Available Neonatal bacterial sepsis is one of the major cause of morbidity and mortality in neonates. This retrospective study was performed to determine the incidence of bacterial sepsis with focus on Gram negative organisms in neonates admitted at Beheshti Hospital in Kashan, during a 3-yr period, from September 2002 to September 2005. Blood culture was performed on all neonates with risk factors or signs of suggestive sepsis. Blood samples were cultured using brain heart infusion (BHI broth according to standard method. From the 1680 neonates 36% had positive blood culture for Pseudomans aeruginosa, 20.7% for Coagulase negative Staphylococci, and 17% for Klebsiella spp. Gram-negative organisms accounted for 72.1% of all positive cultures. The overall mortality rate was 19.8% (22 /111 of whom 63.6% (14 /22 were preterm. Pseudomona aeruginosa and Klebsiella spp. showed a high degree of resistance to commonly used antibiotics (ampicillin, gentamicin as well as third generation cephalosporins. Continued local surveillance studies are urged to monitor emerging antimicrobial resistance and to guide interventions to minimize its occurrence.

    2011-11-01

    Full Text Available Abstract Background Neonatal mice developed neurological disease and pulmonary dysfunction after an infection with a mouse-adapted human Enterovirus 71 (EV71 strain MP4. However, the hallmark of severe human EV71 infection, pulmonary edema (PE, was not evident. Methods To test whether EV71-induced PE required a proinflammatory cytokine response, exogenous pro-inflammatory cytokines were administered to EV71-infected mice during the late stage of infection. Results After intracranial infection of EV71/MP4, 7-day-old mice developed hind-limb paralysis, pulmonary dysfunction, and emphysema. A transient increase was observed in serum IL-6, IL-10, IL-13, and IFN-γ, but not noradrenaline. At day 3 post infection, treatment with IL-6, IL-13, and IFN-γ provoked mild PE and severe emphysema that were accompanied by pulmonary dysfunction in EV71-infected, but not herpes simplex virus-1 (HSV-1-infected control mice. Adult mice did not develop PE after an intracerebral microinjection of EV71 into the nucleus tractus solitarii (NTS. While viral antigen accumulated in the ventral medulla and the NTS of intracerebrally injected mice, neuronal loss was observed in the ventral medulla only. Conclusions Exogenous IL-6, IL-13, and IFN-γ treatment could induce mild PE and exacerbate pulmonary abnormality of EV71-infected mice. However, other factors such as over-activation of the sympathetic nervous system may also be required for the development of classic PE symptoms.

  15. Increased pulmonary vascular permeability as a cause of re-expansion edema in rabbits

    International Nuclear Information System (INIS)

    In order to study the mechanism(s) underlying re-expansion edema, we measured the concentration of labeled albumin (RISA) in the extravascular, extracellular water (EVECW) of the lung as a measure of pulmonary vascular permeability. Re-expansion edema was first induced by rapid re-expansion of rabbit lungs that had been collapsed for 1 wk by pneumothorax. The RISA in EVECW was expressed as a fraction of its plasma concentration: (RISA)L/(RISA)PL. The volume of EVECW (ml/gm dry lung) was measured using a 24Na indicator. Results in re-expansion edema were compared with normal control lungs and with oleic acid edema as a model of permeability edema. In re-expanded lungs, EVECW (3.41 +/- SD 1.24 ml/g) and (RISA)L/(RISA)PL 0.84 +/- SD 0.15) were significantly increased when compared with normal control lungs (2.25 +/- 0.41 ml/g and 0.51 +/- 0.20, respectively). Results in oleic acid edema (5.66 +/- 2.23 ml/g and 0.84 +/- 0.23) were similar to re-expansion edema. This suggested that re-expansion edema is due to increased pulmonary vascular permeability caused by mechanical stresses applied to the lung during re-expansion

    Full Text Available Fetal thyrotoxicosis is a rare disease occurring in 1 out of 70 pregnancies with Grave′s disease or in 1 out of 4000-50,000 deliveries. The mortality is 12-20%, usually from heart failure, but other complications are tracheal compression, infections and thrombocytopenia. It results from transfer of thyroid stimulating immunoglobulins from mother to fetus through the placenta. This transplacental transfer begins around 20 th week of pregnancy and reaches its maximum by 30 th week. These autoantibodies bind to the fetal thyroid stimulating hormone (TSH receptors and increase the secretion of the thyroid hormones. The mother has an active autoimmune thyroid disease or has been treated for it in the past. She may be absolutely euthyroid due to past treatment by drugs, surgery or radioiodine ablation, but still have active TSH receptor stimulating autoantibodies, which can cause fetal thyrotoxicosis. The other features of this disease are fetal tachycardia, fetal goiter and history of spontaneous abortions and findings of goiter, ascites, craniosyntosis, fetal growth retardation, maceration and hydrops at fetal autopsy. If untreated, this disease can result in intrauterine death. The treatment for this disease consists of giving carbimazole to the mother, which is transferred through the placenta to the fetus. The dose of carbimazole is titrated with the fetal heart rate. If the mother becomes hypothyroid due to carbimazole, thyroxine is added taking advantage of the fact that very little of thyroxine is transferred across the placenta. Neonatal thyrotoxicosis patients are very sick and require emergency treatment. The goal of the treatment is to normalize thyroid functions as quickly as possible, to avoid iatrogenic hypothyroidism while providing management and supportive therapy for the infant′s specific signs and symptoms.

    Neonatal jaundice is a common condition that occurs in newborn infants in the first week of life. Today, techniques used for detection are required blood samples and other clinical testing with special equipment. The aim of this study is creating a non-invasive system to control and to detect the jaundice periodically and helping doctors for early diagnosis. In this work, first, a patient group which is consisted from jaundiced babies and a control group which is consisted from healthy babies are prepared, then between 24 and 48 h after birth, 40 jaundiced and 40 healthy newborns are chosen. Second, advanced image processing techniques are used on the images which are taken with a standard smartphone and the color calibration card. Segmentation, pixel similarity and white balancing methods are used as image processing techniques and RGB values and pixels' important information are obtained exactly. Third, during feature extraction stage, with using colormap transformations and feature calculation, comparisons are done in RGB plane between color change values and the 8-color calibration card which is specially designed. Finally, in the bilirubin level estimation stage, kNN and SVR machine learning regressions are used on the dataset which are obtained from feature extraction. At the end of the process, when the control group is based on for comparisons, jaundice is succesfully detected for 40 jaundiced infants and the success rate is 85 %. Obtained bilirubin estimation results are consisted with bilirubin results which are obtained from the standard blood test and the compliance rate is 85 %. PMID:27229489

A população do estudo foi a coorte de 101 mil nascidos vivos, residentes em Goiânia, de 1992 a 1996. As probabilidades de morte infantil foram estimadas mediante o cotejo dos arquivos de óbitos e de nascidos vivos. Para minimizar as flutuações aleatórias das taxas, empregou-se o método Bayesiano empírico. A unidade de análise do padrão espacial foi constituída pelos 65 distritos urbanos de planejamento. Para análise de autocorrelação espacial foram utilizados: Moran "global", Moran local e estatística Gi* local. Os componentes neonatal e pós-neonatal da mortalidade infantil evidenciaram autocorrelação espacial estatisticamente significativa. No período pós-neonatal, os distritos de risco concentram-se nas regiões periféricas do município. No período neonatal, o padrão de ocorrência é heterogêneo, havendo distritos de alto risco distribuídos em todas as regiões, inclusive na região Central de Goiânia.The aim of this study was to investigate the spatial pattern of neonatal and post-neonatal mortality in the city of Goiânia, Central Brazil. Analyses were based on linked birth and death certificates relating to 101,000 in-hospital live births from mothers residing in the city of Goiânia over the 1992-1996 period. Overall neonatal and post-neonatal mortality probabilities were calculated using the linked database. The empirical Bayes method was applied to smooth the estimated rates and minimize random fluctuation. Spatial units of analysis were 65 urban districts, corresponding to the urban planning sectors. The following exploratory spatial analyses were applied: "global" Moran's I statistic, local Moran LISA map, and Gi* local statistics. For both neonatal and post-neonatal mortality there was statistically significant spatial autocorrelation

    Full Text Available Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial bleeding with high mortality and usually related to traumatic labor or coagulation disorders. Subgaleal hemorrhage complications result from massive bleeding. We present a neonate with unremarkable family history and uneventful pregnancy with a vaginal delivery with no instrumentation, presenting with severe subgaleal bleeding at 52 hours of life. Aggressive support measures were implemented and bleeding managed. The unexpected bleeding lead to a coagulation study and the diagnosis of severe hemophilia A. There were no known sequelae. This case shows a rare hemophilia presentation reflecting the importance of coagulation studies when faced with unexplained severe bleeding.

    Choice tests were conducted to determine feeding preferences of European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), neonates for 15 species of plants. Percentage of neonates accepting (found on) each leaf disc after 24 h was measured using choice tests. Initially, nine species of plants were evaluated. The following year, 10 plant species were evaluated during O. nubilalis first generation and 11 species during the second generation. Pennsylvania smartweed, Polygonum pennsylvanicum (L.), had the highest percentage of neonates accepting leaf discs in both years. Other plants with high acceptance rates included swamp smartweed, Polygonum amphibium L.; velvetleaf, Abutilon theophrasti Medicus; cocklebur, Xanthium strumarium L.; and yellow foxtail, Setaria glauca (L.). Corn, Zea mays L., consistently had low percentages of neonates accepting leaf discs along with common waterhemp, Amaranthus rudis Sauer. Implications these results may have on O. nubilalis host plant selection in central Iowa's corn dominated landscape are considered. PMID:17195664

    Posterior lumbar subcutaneous (PLS) edema on spine magnetic resonance (MR) images is a common incidental, though neglected finding. This study was undertaken to investigate the relations between PLS edema and pathologic conditions. Between January and December 2009, 138 patients with PLS edema, but without a spinal tumor or a history of recent surgery or trauma, and 80 infectious spondylitis patients without PLS edema were enrolled in this retrospective study. Available medical records and lumbar spine MR images were evaluated. The degree of edema was quantified using an arbitrary scoring system. Further, the correlations between the degree of edema and age, sex, body mass index (BMI), degeneration of posterior spinal structures (PSS) and infectious spondylitis were analyzed. Of the 93 cases with a calculable BMI, 61 (66%) had a BMI of > 23 kg/m2. Correlations between the degree of edema and sex, age and BMI grade were all statistically non-significant. Thirty-three cases (24%) had an underlying disease, such as heart problem, diabetes mellitus, liver cirrhosis, chronic renal failure, extra-spinal tumor or connective tissue disorder. The numbers of cases with infectious spondylitis and an idiopathic condition was 61 (44%) and 44 (32%), respectively. The grade of infectious spondylitis was not found to be significantly associated with the degree of edema (p = 0.084). In cases with an idiopathic condition, the correlation between the degree of edema and PSS degeneration was statistically significant (p = 0.042). Radiologists should not disregard PLS edema, because it is related to an underlying disease and thus may be of clinical significance.

    Full Text Available Abstract Background Estimated 17,000 neonates (≤ 28 days of age die in Vietnam annually, corresponding to more than half of the child mortality burden. However, current knowledge about these neonates is limited. Prematurity, asphyxia and congenital malformations are major causes of death in neonates worldwide. To improve survival and long term development, these vulnerable neonates need access to the specialized neonatal care existing, although limited, in lower middle-income countries like Vietnam. The aim of this study was to describe these conditions in a specialized Vietnamese hospital, compared to a Danish hospital. Methods We performed a comparative observational study of all neonates admitted to a tertiary pediatric hospital in South Vietnam in 2009–2010. The data were prospectively extracted from the central hospital registry and included basic patient characteristics and diagnoses (International Classification of Diseases, 10th revision. Prematurity, asphyxia and designated congenital malformations (oesophageal atresia, gastroschisis, omphalocoele, diaphragmatic hernia and heart disease were investigated. In a subgroup, the prematurity diagnosis was validated using a questionnaire. The hospitalization ratio of each diagnosis was compared to those obtained from a Danish tertiary hospital. The Danish data were retrieved from the neonatal department database for a ten-year period. Results The study included 5763 neonates (missing Conclusion Our findings suggest the investigated diagnoses were underrepresented in the Vietnamese study hospital. In contrast, relatively mild diagnoses were frequent. These results indicate the use of specialized care may not be optimal. Pre-hospital selection mechanisms were not investigated and additional studies are needed to optimise utilisation of specialized care and improve neonatal survival.

    Full Text Available AIM: To study the determinant of mortality on extramural arrival of sick newborns and mode of neonatal transport at tertiary care C entre . BACKGROUND: Neonatal transport system in our country is major gap in holistic newborn care and acute neonatal physiology is deranged during transport which adversely affects the mortality and morbidity of sick newborns. MATERIAL & METHODS: This is prospective observational cohort study carried out in out born neonatal intensive care unit over a period of one year. Inclusion cr iteria were age up to 28 days, delivered at home or private nursing home or any health centre; and exclusion criteria were age more than 28 days, abandoned newborns and those delivered in the institution of study . A predesigned and tested proforma was used to record information by the pediatric resident on duty at time of neonatal admission. Data were analysed and tabulated, for analysis of data software STATISTIX was used, chi - square test for dichotomous variables and multiple logistic regression for predi ctors of mortality. RESULT: Out of 200 newborns 146 were male and 54 were female, 140 were term and 59 were preterm, 39 newborns expired and common mode of transport was taxi 47%, bus 16%, auto 16% and ambulance 2.5%. The common factors determining the out come were low admission weight, prematurity, longer duration of transport and deranged physiological factors e.g. hypothermia, respiratory distress, prolonged CRT and central cyanosis. CONCLUSION: This study concludes that neonatal transport in our country is self - supported; the ideal element of neonatal transport is major gap in holistic neonatal care. Thus we suggest RUSH - IN FACILITY for neonatal transport.

    Purpose: To evaluate whether initiation of running in sedentary individuals would lead to bone marrow edema on MR images, within the time span of 1 week. Materials and methods: The feet of 10 healthy volunteers were imaged by MR imaging before and after running during 30 min a day for 1 week. The images were evaluated by consensus of 2 musculoskeletal radiologists who graded the presence of bone marrow edema on a 4-point scale. Edema scores and number of bones involved before and after running were compared statistically. Results: Edema was present on the baseline images in 3 subjects. After running edema showed an increase or was present in 5 subjects. The changes after running were statistically significant. Bones involved were the talus, calcaneus, navicular bone, cuboid bone, and 5th metatarsal. Conclusion: Edema patterns can be seen in the feet of asymptomatic individuals. During initiation of running an increase of edema or development of new edema areas can be seen.

    Background Outcomes of intravitreal antivascular endothelial growth factor injections are variable among patients with diabetic macular edema (DME). The aim of this study was to determine the ocular and systemic predictors of DME response to intravitreal bevacizumab (IVB). Methods Retrospective review over 2 years of 78 eyes from 54 patients. An anatomical response to IVB was defined as a 20% reduction in central macula thickness after the first course (three injections) of IVB. Results Twenty-eight percent of patients had an anatomical response after the first course of IVB. Systemic hypertension (odds ratio, 95% confidence interval: 12.1, 0.7–21) was a statistically significant predictor (P=0.025) of a good response to IVB, whereas previous macular laser was a statistically significant (P=0.0005) predictor of a poor response (0.07, 0.01–0.32). Sixty-eight percent of eyes underwent subsequent treatment for DME after the first course of IVB. The visual acuity gain at 24 months in hypertensive (0.7±3.6 letters) and nonhypertensive (5.2±3.7 letters) patients was not significantly different (P=0.41). Conclusion Hypertension and previous macular laser were positive and negative predictors of response to IVB, respectively. However, long-term visual acuity changes were not significantly different between eyes with and without systemic hypertension. PMID:27799737

Forty-one patients with a previous history of treatment for DME including at least three consecutive intravitreal ranibizumab injections were enrolled in this retrospective study. Main outcome measures were change in best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure from baseline to 6th month. At the baseline, the mean CMT was 572.4 ± 123.1 μm which improved to 264.2 ± 114.4, 317.7 ± 141.7, 410.6 ± 169.1, and 382.8 ± 181.5 μm at the 1st, 3rd, 5th, and 6th month, respectively (p dexamethasone implantation caused a significant improvement of BCVA and reduction of CMT in the patients with persistent DME that were unresponsive to 3 consecutive ranibizumab injections. However, retreatment before 6 months in the majority of the patients was needed despite the beneficial effects after the index procedure. PMID:26644130

    Full Text Available PURPOSE: Volumetric measurements of neonatal brain tissues may be used as a biomarker for later neurodevelopmental outcome. We propose an automatic method for probabilistic brain segmentation in neonatal MRIs. MATERIALS AND METHODS: In an IRB-approved study axial T1- and T2-weighted MR images were acquired at term-equivalent age for a preterm cohort of 108 neonates. A method for automatic probabilistic segmentation of the images into eight cerebral tissue classes was developed: cortical and central grey matter, unmyelinated and myelinated white matter, cerebrospinal fluid in the ventricles and in the extra cerebral space, brainstem and cerebellum. Segmentation is based on supervised pixel classification using intensity values and spatial positions of the image voxels. The method was trained and evaluated using leave-one-out experiments on seven images, for which an expert had set a reference standard manually. Subsequently, the method was applied to the remaining 101 scans, and the resulting segmentations were evaluated visually by three experts. Finally, volumes of the eight segmented tissue classes were determined for each patient. RESULTS: The Dice similarity coefficients of the segmented tissue classes, except myelinated white matter, ranged from 0.75 to 0.92. Myelinated white matter was difficult to segment and the achieved Dice coefficient was 0.47. Visual analysis of the results demonstrated accurate segmentations of the eight tissue classes. The probabilistic segmentation method produced volumes that compared favorably with the reference standard. CONCLUSION: The proposed method provides accurate segmentation of neonatal brain MR images into all given tissue classes, except myelinated white matter. This is the one of the first methods that distinguishes cerebrospinal fluid in the ventricles from cerebrospinal fluid in the extracerebral space. This method might be helpful in predicting neurodevelopmental outcome and useful for evaluating

    Improved neonatal survival rates and antenatal diagnostic imaging is generating a growing demand for postnatal MRI examinations. Neonatal brain MRI is now becoming standard clinical care in many settings, but with the exception of some research centres, the technique has not been optimised for imaging neonates and small children. Here, we review some of the challenges involved in neonatal MRI, including recent advances in overall MR practicality and nursing practice, to address some of the ways in which the MR experience could be made more neonate-friendly.

    Background: Neonatal nasopharyngeal teratomas are extremely rare and there are few reports describing both CT and MRI features of these lesions. Objective: To describe the CT and MRI appearances of neonatal nasopharyngeal teratoma. Materials and methods: Three neonates with nasopharyngeal teratomas and severe respiratory distress were reviewed. Results: The nasopharyngeal mass resulted in severe respiratory compromise requiring urgent intervention. Characteristic mandibular and pterygoid plate abnormalities demonstrated by CT and MRI are described. Conclusions: Prenatal MRI enables the diagnosis, delineates tumour extent and allows planned delivery. CT and MRI play a key role in differentiating neonatal nasopharyngeal teratomas from other causes of a neonatal neck mass, thus optimising management. (orig.)

    A highly portable, fast, safe and affordable imaging system that provides interpretable images of brain function in full- and pre-term neonates within a few seconds has been applied to neonates with normal and pathological states. We have used a uniquely sensitive optical tomography system, termed phased array, which has revealed significant functional responses, particularly to parietal stimulation in neonate brain. This system can indicate the blood concentration and oxygenation change during the parietal brain activation in full- and pre-term neonates. The preliminary clinical results, especially a longitudinal study of a cardiac arrest neonate, suggest a variety of future applications.

    The impact of maternal health services on perinatal and neonatal mortality depends on both the quantitative and qualitative coverage of pregnant women with obstetric services. In rural areas this becomes all the more difficult because of the requirement of a large decentralized infrastructure extending from village based health workers and subcentres to the Primary Health Centre and tertiary levels of referral. An effective introduction of socio-cultural, biomedical and managerial interventions is required to reduce perinatal and neonatal mortality. A community based surveillance and monitoring system is central to and facilitates the introduction of all other interventions. Finally, the system operated by grass-root level workers is a motivational tool for achieving expected levels of performance. PMID:2630471

  13. Neonatal withdrawal syndrome: Case report

    Full Text Available Introduction. Maternal drug abuse has increased over the past decade. It has a multiple negative influence on a pregnant woman, as well as her newborn. Practically, every drug taken during pregnancy crosses the placenta, and the developing fetus may also be affected by the effects of a drug. After delivery, an infant of a drug-abusing mother may potentially develop neonatal withdrawal syndrome. Existing studies on the neonatal effects of drug exposure in utero are subject to many factors. Many studies have relied on the history obtained from the mother, which is innacurate. Urine testing for drug abuse does not reflect exposure to a drug through pregnancy and does not provide quantitative information. Social and economic deprivation is common among drug abusers, and this factor has a major effect on long term studies of infant outcome. The purpose of this article is to underline the problems during management of a neonatal withdrawal syndrom, and growing incidence of it in our society. Case report. A case of an infant of a heroin-abusing mother is reported. Conclusion. It is very important to take care of an infant with neonatal withdrawal syndrome, but it is also of a great importance to supervise these children for a long period of time.

    1984-01-01

    Edema severity was scored by herd personnel in six North Carolina Holstein herds from 1 (none) to 5 (extremely severe). Cows (2612) were scored at calving and 1 and 2 wk postpartum. Total score was calculated as the sum of these three scores. Official Holstein-Friesian classification descriptive udder trait codes were available on a subset of the cows. All statistical analyses were within lactation and included adjustments for herd-year and age as well as classifier and stage of lactation where appropriate. Correlations between corresponding edema scores for first and second lactations were .18, .18, .19, and .20 for scores at calving, 1 wk, 2 wk, and for total score. Stepwise regression procedures showed that udder support codes were associated with a larger amount of variation of edema scores than for any other single mammary trait code. Fore and rear udder codes also were associated with significant variation of edema scores in some analyses. Prediction models showed edema was a significant predictor of subsequent udder support codes, although udder trait codes were not significant predictors of subsequent edema severity. It appeared that severe edema may be one of the causes of pendulous udders. PMID:6707304

    Full Text Available BACKGROUND: Pulmonary edema plays a pivotal role in the pathophysiology of respiratory syncytial virus (RSV-induced respiratory failure. In this study we determined whether treatment with TIP (AP301, a synthetic cyclic peptide that mimics the lectin-like domain of human TNF, decreases pulmonary edema in a mouse model of severe human RSV infection. TIP is currently undergoing clinical trials as a therapy for pulmonary permeability edema and has been shown to decrease pulmonary edema in different lung injury models. METHODS: C57BL/6 mice were infected with pneumonia virus of mice (PVM and received TIP or saline (control group by intratracheal instillation on day five (early administration or day seven (late administration after infection. In a separate set of experiments the effect of multiple dose administration of TIP versus saline was tested. Pulmonary edema was determined by the lung wet-to-dry (W/D weight ratio and was assessed at different time-points after the administration of TIP. Secondary outcomes included clinical scores and lung cellular response. RESULTS: TIP did not have an effect on pulmonary edema in different dose regimens at different time points during PVM infection. In addition, TIP administration did not affect clinical severity scores or lung cellular response. CONCLUSION: In this murine model of severe RSV infection TIP did not affect pulmonary edema nor course of disease.

    We investigated the relation between left ventricular dysfunction and myocardial edema in dogs with heartworm (Dirofilaria immitis) infection that were undergoing cardiopulmonary bypass. Dogs with and without D immitis were anesthetized by continuous thiopental infusion and were mechanically ventilated. Sonomicrometry crystals were placed on the long and short axes of the left ventricle, and a Millar pressure transducer was placed in the left ventricular chamber. Pressure-volume loops were digitized and continuously recorded. Dogs with and without D immitis were placed on standard hypothermic cardiopulmonary bypass, with 1 hour of aortic cross-clamp. Wet-to-dry weight ratio corrected for residual blood volume was used to quantitate the volume of myocardial edema. Preload recruitable stroke work was used as a preload-independent index of systolic function. Tau, the isovolumic relaxation time constant, was determined to assess diastolic relaxation. Dogs with D immitis had increased baseline myocardial wet-to-dry weight ratio. After cardiopulmonary bypass, myocardial edema increased in all dogs. Acute edema attributable to cardiopulmonary bypass decreased preload recruitable stroke work in all dogs of both groups, and dogs with D immitis could not be weaned from cardiopulmonary bypass. Myocardial edema increased diastolic relaxation times (tau) in dogs with and without D immitis. We conclude that cardiopulmonary bypass and heartworm infection induce myocardial edema. This edema compromises left ventricular systolic and diastolic function making D immitis an important confounding factor in weaning dogs from cardiopulmonary bypass. PMID:7717590

    We describe the case of a patient with a recent history of high back pain, with magnetic resonance imaging (MRI) of the thoracic spine showing intervertebral disk herniation into the spongious bone of the vertebral body of T9 that might have caused diffuse, low signal intensity on fluid-attenuated inversion recovery T1-weighted (FLAIR-T1W) images, high signal intensity magnetic resonance (MR) on T2-weighted (T2W) images and T2-weighted fat-suppressed images (T2W-FSIs) and marked enhancement on the vertebral body of T9 with gadolinium on T1-weighted fat-suppressed images (T1W-FSIs) images. Those findings suggested diffuse edema and might be indistinguishable from tumoral or inflammatory diseases, but the plain films and the reformatted sagittal computed tomography scans of the thoracic spine were helpful to show a calcified part of the intervertebral disk migrating into the vertebral body of T9. The patient made full recovery from the symptoms after conservative treatment and at the follow-up MRI showed normalization of the bone marrow signal intensity of the vertebral body of T9. (orig.)

    2011-01-01

    Full Text Available There are several pieces of evidence showing occurrence of pulmonary edema (PE in healthy subjects in extreme conditions consisting of extreme psychophysical demand in normal environment and psychophysical performances in extreme environment. A combination of different mechanisms, such as mechanical, hemodynamic, biochemical, and hypoxemic ones, may underlie PE leading to an increase in lung vascular hydrostatic pressure and lung vascular permeability and/or a downregulation of the alveolar fluid reabsorption pathways. PE can be functionally detected by closing volume measurement and lung diffusing capacity test to different gases or directly visualized by multiple imaging techniques. Among them chest ultrasonography can detect and quantify the extravascular lung water, creating “comet-tail” ultrasound artefacts (ULCs from water-thickened pulmonary interlobular septa. In this paper the physiopathological mechanisms of PE, the functional and imaging techniques applied to detect and quantify the phenomenon, and three models of extreme conditions, that is, ironman athletes, climbers and breath-hold divers, are described.

    Optical coherence tomography (OCT) is a powerful imaging tool that is particularly useful for exploring retinal abnormalities in ophthalmological diseases. Recently, it has been used to track changes in the eye associated with neurological diseases such as multiple sclerosis (MS) where certain tissue layer thicknesses have been associated with disease progression. A small percentage of MS patients also exhibit what has been called microcystic macular edema (MME), where uid collections that are thought to be pseudocysts appear in the inner nuclear layer. Very little is known about the cause of this condition so it is important to be able to identify precisely where these pseudocysts occur within the retina. This identi cation would be an important rst step towards furthering our understanding. In this work, we present a detection algorithm to nd these pseudocysts and to report on their spatial distribution. Our approach uses a random forest classi er trained on manual segmentation data to classify each voxel as pseudocyst or not. Despite having a small sample size of ve subjects, the algorithm correctly identi es 84.6% of pseudocysts as compared to manual delineation. Finally, using our method, we show that the spatial distribution of pseudocysts within the macula are generally contained within an annulus around the fovea.

A. number of landmark clinical trials have provided strong evidence of the safety and efficacy of agents such as anti-vascular endothelial growth factors for the treatment of DME. Decades of clinical research, ranging from the early treatment of diabetic retinopathy study to the present-day randomized clinical trials (RCTs) testing novel agents, have shifted the goal of therapy from preventing vision loss to ensuring a maximum visual gain. Systematic study designs have provided robust data with an attempt to optimize the treatment regimens including the choice of the agent and timing of therapy. However, due to a number of challenges in the management of DME with approved agents, further studies are needed. For the purpose of this review, an extensive database search in English language was performed to identify prospective, RCTs testing pharmacological agents for DME. In order to acquaint the reader with the most relevant data from these clinical trials, this review focuses on pharmacological agents that are currently approved or have widespread applications in the management of DME.

    Full Text Available IntroductionDyspnea refers to difficulty in breathing, and short and shallow breaths. This sign is seen in numerous diseases due to pulmonary, cardiac, metabolic and neurological causes. Among cardiac causes, heart failure is considered the main cause of dyspnea.Cardiac failure is a clinical syndrome associated with a set of symptoms (dyspnea, and fatigue and signs (edema and rales. Common causes of cardiac failure include: myocardial infarction, ischemic heart disease, hypertension, valvular heart diseases, and cardiomyopathy. Among uncommon causes of heart failure, endocrine disorders such as Cushing’s syndrome can be cited. Cushing’s syndrome can present itself in less common forms such as dyspnea due to heart failure. Cushing’s syndrome’s cardiovascular complications usually occur due to hypertension, end organ damage such as left ventricular heart failure, diastolic and ischemic myocardial heart failure, which are rather seen in chronic cases of the disease and are often irreversible.Transient heart failure in patients with Cushing’s syndrome, due to adrenal adenoma, has been reported in a number of patients. In this case report, a patient is introduced who presented to emergency department with severe dyspnea (FC III, and was ultimately diagnosed with Cushing’s syndrome after work up. Three months after treatment of Cushing’s syndrome, dramatic improvement was observed in this patient’s cardiac function.

    High-altitude pulmonary edema (HAPE) is a potentially fatal condition, occurring at altitudes greater than 3,000 m and affecting rapidly ascending, non-acclimatized healthy individuals. However, the lack of biomarkers for this disease still constitutes a bottleneck in the clinical diagnosis. Here, ultra-high performance liquid chromatography coupled with Q-TOF mass spectrometry was applied to study plasma metabolite profiling from 57 HAPE and 57 control subjects. 14 differential plasma metabolites responsible for the discrimination between the two groups from discovery set (35 HAPE subjects and 35 healthy controls) were identified. Furthermore, 3 of the 14 metabolites (C8-ceramide, sphingosine and glutamine) were selected as candidate diagnostic biomarkers for HAPE using metabolic pathway impact analysis. The feasibility of using the combination of these three biomarkers for HAPE was evaluated, where the area under the receiver operating characteristic curve (AUC) was 0.981 and 0.942 in the discovery set and the validation set (22 HAPE subjects and 22 healthy controls), respectively. Taken together, these results suggested that this composite plasma metabolite signature may be used in HAPE diagnosis, especially after further investigation and verification with larger samples.

    Recently, the consequences of diabetes on the central nervous system (CNS) have received great attention. However, the mechanisms by which hyperglycemia affects the central nervous system remain poorly understood. In addition, recent studies have shown that hyperglycemia induces oxidative damage in the adult rat brain. In this regard, no study has assessed oxidative stress as a possible mechanism that affects the brain normal function in neonatal hyperglycemic rats. Thus, the present study aimed to investigate whether neonatal hyperglycemia elicits oxidative stress in the brain of neonate rats subjected to a streptozotocin-induced neonatal hyperglycemia model (5-day-old rats). The activities of glucose-6-phosphate-dehydrogenase (G6PD), 6-phosphogluconate-dehydrogenase (6-PGD), NADPH oxidase (Nox), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSHPx), the production of superoxide anion, the thiobarbituric acid-reactive substances (TBA-RS), and the protein carbonyl content were measured. Neonatal hyperglycemic rats presented increased activities of G6PD, 6PGD, and Nox, which altogether may be responsible for the enhanced production of superoxide radical anion that was observed. The enhanced antioxidant enzyme activities (SOD, CAT, and GSHPx) that were observed in neonatal hyperglycemic rats, which may be caused by a rebound effect of oxidative stress, were not able to hinder the observed lipid peroxidation (TBA-RS) and protein damage in the brain. Consequently, these results suggest that oxidative stress could represent a mechanism that explains the harmful effects of neonatal hyperglycemia on the CNS.

    Full Text Available Introduction: Nosocomial infections are one of the important mortality and morbidity reasons among newborns. For this reason recognition of infection factors and the resistance to antimicrobials in intensive care unit is very important in terms of rational antibiotic use. Materials and Methods: Nosocomial infections seen in our neonatal intensive care unit between 2009 and 2011 were retrospectively analyzed. Isolated strains, antibiotic sensitivities, the use of invasive tool, infectious species and infection rates were determined according to the data provided by National Nosocomial Infections Surveillance Control Unit. Results: A total of 4258 patients were observed for 34625 patient days, 6536 ventilator days, 98 urinary catheter days, 601 central venous catheter days and 590 umbilical catheter days. The infection rate was 3.26% (139/4258 and the incident density was 4.01‰. Pneumonia was on the first rank (61; 43% and it was in ventilator association form. 36 strains were isolated as the infectious agents. The rates of gram negative factors was 23 (63.88%, gram positive factors was 8 (22.22% and Candida spp. was 5 (13.88 %. The most frequently isolated gram negative strains were Klebsiella spp. (7; 19.4% and Pseudomonas spp. (7; 19.4 %. The most effective antibiotics in Enterobactericeae spp. were meropenem and imipenem. In enteric gram-negative rods, extended-spectrum beta-lactamase positivity was 63.64%. In the neonatal intensive care unit, ventilator-associated pneumonia rate was 6.73% and the ventilator use ratio was 19%. Conclusions: In conclusion, each intensive care unit should determne the factors and follow antimicrobial resistant patterns. Empiric antibiotic treatment strategy should be established. Decreasing or totally preventing hospital infections would be possible by active surveillance system, adoption infection control guidelines, limitation of instrument use and rational antibiotic use rules.

    For years, the standard of care for branch-retinal-vein-occlusion-associated macular edema was initial observation followed by grid-pattern laser photocoagulation for persistent edema. Newer pharmacologic options have revolutionized the management of branch-retinal-vein-occlusion-associated macular edema, and the visual outcomes of these eyes are better than ever. However, a variety of available treatment options including intravitreal corticosteroids and intravitreal anti-vascular endothelial growth factor agents have established novel challenges with regard to appropriate drug selection. This review summarizes the available clinical studies with special emphasis on the comparison of intravitreal aflibercept with ranibizumab, bevacizumab, and steroid agents. PMID:27022238

    Full Text Available We investigated the role of the WW domain-containing oxidoreductase (wwox gene in the embryonic development of zebrafish, with particular emphasis on intracellular Ca2+ dynamics because Ca2+ is an important intracellular messenger. Comparisons between zebrafish wwox and human WWOX sequences identified highly conserved domain structures. wwox was expressed in developing heart tissues in the zebrafish embryo. Moreover, wwox knockdown induced pericardial edema with similarities to conditions observed in human breast cancer. The wwox knockdown embryos with the edema died within a week. High Ca2+ levels were observed at the boundary between the edema and yolk in wwox knockdown embryos.

    Full Text Available Diabetic retinopathy is fast emerging as a leading cause of newly diagnosed legal blindness amongst the working population. Macular edema, as it is commoner, accounts for more vision impairment than neovascular proliferation in diabetic patients. Laser photocoagulation, which is the standard treatment of macular edema, is associated with significant complications and an improvement in visual acuity is unsatisfactory. Intravitreal injection of corticosteroids (especially triamcinolone acetonide is an emerging treatment modality in the management of diabetic macular edema. This article presents an overview of the principles, technique and complications associated with this procedure.

    Full Text Available Abstract Background Vasogenic edema dynamically accumulates in many brain disorders associated with brain inflammation, with the critical step of edema exacerbation feared in patient care. Water entrance through blood-brain barrier (BBB opening is thought to have a role in edema formation. Nevertheless, the mechanisms of edema resolution remain poorly understood. Because the water channel aquaporin 4 (AQP4 provides an important route for vasogenic edema resolution, we studied the time course of AQP4 expression to better understand its potential effect in countering the exacerbation of vasogenic edema. Methods Focal inflammation was induced in the rat brain by a lysolecithin injection and was evaluated at 1, 3, 7, 14 and 20 days using a combination of in vivo MRI with apparent diffusion coefficient (ADC measurements used as a marker of water content, and molecular and histological approaches for the quantification of AQP4 expression. Markers of active inflammation (macrophages, BBB permeability, and interleukin-1β and markers of scarring (gliosis were also quantified. Results This animal model of brain inflammation demonstrated two phases of edema development: an initial edema build-up phase during active inflammation that peaked after 3 days (ADC increase was followed by an edema resolution phase that lasted from 7 to 20 days post injection (ADC decrease and was accompanied by glial scar formation. A moderate upregulation in AQP4 was observed during the build-up phase, but a much stronger transcriptional and translational level of AQP4 expression was observed during the secondary edema resolution phase. Conclusions We conclude that a time lag in AQP4 expression occurs such that the more significant upregulation was achieved only after a delay period. This change in AQP4 expression appears to act as an important determinant in the exacerbation of edema, considering that AQP4 expression is insufficient to counter the water influx during the build

Patients and methods: Prospective study in patients with DME insufficiently responsive to laser and anti-vascular endothelial growth factor (anti-VEGF. Patients with history of rise of intraocular pressure after intravitreal corticosteroids were excluded. Results: The macular edema rapidly decreased both in group 1 (prior laser only; n=7 eyes and group 2 (prior laser and ≥3 monthly anti-VEGF therapy; n=10 eyes and central subfield thickness was reduced by -299 µm (P=0.008 and -251 µm (P=0.016 at 12 months, respectively. Mean area under the curve from baseline to last value for pseudophakic eyes was +4.2 letters in group 1 and +9.5 letters in group 2. Overall, the FAc implant was well tolerated. Conclusion: This prospective study confirms the efficacy of the FAc implant in DME patients insufficiently responsive to laser and anti-VEGF. Moreover, with a careful patient selection, our safety results would support an earlier use of FAc in the DME treatment pathway.

Patients and Methods. 145 patients with DME were followed for 6 months with monthly telephone interviews and medical chart reviews at months 0, 3, and 6. Visual acuity in the worst-seeing eye was assessed at months 0 and 6. DME-related healthcare costs were determined over 6 months, and vision-related (National Eye Institute Visual Functioning Questionnaire and generic (EQ-5D quality of life was assessed at months 0, 3, and 6. Results. Mean age of patients was 63.7 years: 52% were male and 72% had bilateral DME. At baseline, visual acuity was categorized as normal/mild loss for 63.4% of patients, moderate loss for 10.4%, and severe loss/nearly blind for 26.2%. Mean 6-month DME-related costs/patient were as follows: all patients (n=135, $2,092; normal/mild loss (n=88, $1,776; moderate loss (n=13, $1,845; and severe loss/nearly blind (n=34, $3,007. Composite scores for vision-related quality of life declined with increasing visual acuity loss; generic quality of life scores were highest for moderate loss and lowest for severe loss/nearly blind. Conclusions. DME-related costs in the Canadian healthcare system are substantial. Costs increased and vision-related quality of life declined with increasing visual acuity severity.

    Full Text Available El edema agudo pulmonar por presión negativa es una complicación descrita desde 1977 tras la obstrucción de la vía aérea respiratoria, tanto en niños como en adultos. Aunque su etiopatogenia es multifactorial, destaca especialmente la excesiva presión intratorácica negativa causada por la inspiración forzada espontánea de un paciente con la glotis cerrada, que resulta en trasudación de líquido de los capilares pulmonares hacia el espacio alveolointersticial. El edema pulmonar resultante puede aparecer en pocos minutos tras la obstrucción de la vía aérea o de forma diferida al cabo de varias horas. Este cuadro clínico es potencialmente grave, pero habitualmente responde bien al tratamiento con oxigenoterapia, ventilación mecánica a presión positiva y diuréticos. Es importante el diagnóstico de sospecha para adecuar el tratamiento con presteza. Presentamos nuestra experiencia en 3 casos clínicos con edema agudo pulmonar por presión negativa.Negative pressure pulmonary edema is a complication, described since 1977, caused by upper airway obstruction in both children and adults. Although its aetiopathogeny is multifactorial, especially outstanding is excessive negative intrathoracic pressure caused by the forced spontaneous inspiration of a patient against a closed glottis, that causes high arteriole and capillary fluid pressures that favor transudation into the alveolar space The resulting pulmonary edema can appear a few minutes after the obstruction of the airway or in a deferred way after several hours. The clinical manifestations are potentially serious, but normally respond well to treatment with supplemental oxygen, positive pressure mechanical ventilation and diuretics. Diagnostic suspicion is important for acting promptly. We report three clinical cases with acute negative pressure pulmonary edema.

    Significant gaps in healthcare quality and outcomes can be reduced via quality improvement collaboratives (QICs), which improve care by leveraging data and experience from multiple organizations.The Children's Hospital Neonatal Consortium Collaborative Initiatives for Quality Improvement team developed an infrastructure for neonatal QICs. We describe the structure and components of an effective multi-institutional neonatal QIC that implemented the "SLUG Bug" project designed to reduce central line-associated bloodstream infections (CLABSIs).The operational infrastructure of SLUG Bug involved 17 tertiary care neonatal intensive care units with a goal to reduce CLABSI in high-risk neonates. Clinical Practice Recommendations were produced, and the Institute of Healthcare Improvement Breakthrough Series provided the framework for the collaborative. Process measures studied the effectiveness of the collaborative structure.CLABSI rates decreased by 20% during a 12-month study period. Compliance bundle reporting exceeded 80%. A QIC score of 2.5 or more ("improvement") was achieved by 94% of centers and a score 4 or more ("significant improvement") was achieved by 35%.Frequent interactive project meetings, well-defined project metrics, continual shared learning opportunities, and individual team coaching were key QIC success components. Through a coordinated approach and committed leadership, QICs can effectively implement change and improve the care of neonates with complex diagnoses and rare diseases. PMID:25919608

    During 1981-1991 at a rural teaching hospital (Kasturba Hospital) of Mahatma Gandhi Institute of Medical Sciences in Sevagram, Wardha, India, 454 of 13,939 newborns died during the early neonatal period for an early neonatal mortality rate (ENMR) of 33.7/1000 live births. The ENMR for boys was not significantly different from that for girls (36.1 vs. 28.6). Community medicine specialists analyzed data on these early neonatal deaths to examine distribution of early neonatal mortality, especially its relationship with prematurity, low birth weight, birth order, and by sex. They calculated average percent deaths (APD) per hour to examine the dynamics in early neonatal mortality. The mean age at death was lower among newborns of birth order greater than 2 than those of birth order less than 2 (23.47 vs. 26.85 hours; p 0.001). ENMR was higher for newborns of birth order greater than 2 than those of birth order less than 2 (41.74% vs. 27.35%; P 0.001). The mean age at death increased as gestation increased (10.34 for 28 weeks; 24.27 for 28-33 weeks, 31.53 for 33-37 weeks, and 34.43 for 37 weeks; p 0.001). ENMR decreased as gestation increased (850 for 28 weeks; 375 for 28-33 weeks, 147.02 for 33-37 weeks, and 8.77 for 37 weeks; p 0.001). The mean age at death increased as birth weight increased for newborns weighing less than 1500 gms through 2000-2500 gms (23.36-37.13 hours; p 0.001). It was lowest among those weighing more 3000 gms (11.55 gms). ENMR fell as birth weight increased (614.33 for 1500 gms, 116.19 for 1500-2000 gms, 19.38 for 2000-2500 gms, 10.99 for 2500-3000 gms, and 5.41 for 3000 gms; p 0.001). The APD/hour for the first hour of life was 3.74% for a relative risk of 12.9. It decreased steadily as the hours of life increased (3.08% for 1-6 hours, 1.19% for 6-24 hours, 0.67% for 24-72 hours, and 0.29% for 72-168 hours). Knowledge of time of likely death can help providers know where they need to focus their attention to prevent early neonatal deaths.

    Purpose: Posterior reversible encephalopathy syndrome (PRES) is a clinicoradiologic entity characterized by headache, blurred vision and seizures with typical parieto-occipital predominantly vasogenic edema, occasionally with cytotoxic edema. The association between the degree and type of edema in PRES with biochemical parameter, especially serum lactate dehydrogenase, has not been determined. Material and methods: Thirty-five patients with typical clinical symptoms and characteristic MR imaging findings of PRES were included in this study. The extent of brain edema was graded on the anatomical distribution by 2 observers blinded to patients’ clinical record, as well as the type of brain edema determined on DWI and ADC map. The levels of biochemical parameters were correlated with the degree of edema and compared between different types of edema. Results: Serum LDH concentrations between patients with cytotoxic edema and with vasogenic components were not statistically different (NWU test, U = 93.0, Z = 1.818, P = 0.069). Only serum lactate dehydrogenase (LDH) concentration was significantly correlated with the score of brain edema distribution (Spearman's rho correlation, r = 0.721, P = 0.00). No relationship was found between other biochemical parameters and the degree and type of brain edema. Conclusion: Increased serum LDH level, which plays an essential role in endothelial injury, may be a potential risk factor for the development of edema in PRES.

    Full Text Available The treatment of edema in patients with nephrotic syndrome is generally managed by dietary sodium restriction and loop diuretics. However, edema does not improve in some patients despite adequate sodium restriction and maximal dose of diuretics. In such patients, combination of albumin and a loop diuretic may improve edema by diuresis and natriuresis. The response to this combination of albumin and a diuretic has not been observed in all studies. The purpose of this review is to discuss the physiology of diuresis and natriuresis of this combination therapy, and provide a brief summary of various studies that have used albumin and a loop diuretic to improve diuretic-resistant edema. Also, the review suggests various reasons for not observing similar results by various investigators.

    Full Text Available Abstract Background Injurious mechanical ventilation (MV may augment organ injury remote from the lungs. During sepsis, myocardial dysfunction is common and increased endothelial activation and permeability can cause myocardial edema, which may, among other factors, hamper myocardial function. We investigated the effects of MV with injuriously high tidal volumes on the myocardium in an animal model of sepsis. Methods Normal rats and intraperitoneal (i.p. lipopolysaccharide (LPS-treated rats were ventilated with low (6 ml/kg and high (19 ml/kg tidal volumes (Vt under general anesthesia. Non-ventilated animals served as controls. Mean arterial pressure (MAP, central venous pressure (CVP, cardiac output (CO and pulmonary plateau pressure (Pplat were measured. Ex vivo myocardial function was measured in isolated Langendorff-perfused hearts. Cardiac expression of endothelial vascular cell adhesion molecule (VCAM-1 and edema were measured to evaluate endothelial inflammation and leakage. Results MAP decreased after LPS-treatment and Vt-dependently, both independent of each other and with interaction. MV Vt-dependently increased CVP and Pplat and decreased CO. LPS-induced peritonitis decreased myocardial function ex vivo but MV attenuated systolic dysfunction Vt-dependently. Cardiac endothelial VCAM-1 expression was increased by LPS treatment independent of MV. Cardiac edema was lowered Vt-dependently by MV, particularly after LPS, and correlated inversely with systolic myocardial function parameters ex vivo. Conclusion MV attenuated LPS-induced systolic myocardial dysfunction in a Vt-dependent manner. This was associated with a reduction in cardiac edema following a lower transmural coronary venous outflow pressure during LPS-induced coronary inflammation.

    Negative pressure pulmonary edema (NPPE) following the use of the laryngeal mask airway (LMA) is an uncommon and under-reported event. We present a case of a 58-year-old male, who developed NPPE following LMA use. After biting vigorously on his LMA, the patient developed stridor upon emergence, with concurrent appearance of blood-tinged, frothy sputum and pulmonary edema. He subsequently required three days of mechanical ventilation. After discontinuation of mechanical ventilation the patient...

    Abstract We report a case of ipsilateral reexpansion pulmonary edema occurring after the insertion of a chest tube in a patient with spontaneous pneumothorax. The patient received supplemental oxygen via a non-rebreather face mask to compensate for hypoxemia. 24 hours after the acute event, the patient recovered completely without residual hypoxemia. Reexpansion pulmonary edema after the insertion of a thoracic drainage for pneumothorax or pleural effusion is a rare complication with a high m...

    Preventive edema protection using Serrapeptase after standardized one-stage osteotomy procedures of 4 third molars was verified by means of an opto-electronic measuring instrument. This measuring technique proved to be a sensitive tool for demonstrating the efficacy of Serrapeptase in reducing postoperative edema. Although statistically significant, the reduction of soft tissue swelling was only approximately 15% when compared with a patient group without Serrapeptase medication.

    Ischemia resulting from myocardial infarction (MI) promotes VEGF expression, leading to vascular permeability (VP) and edema, a process that we show here contributes to tissue injury throughout the ventricle. This permeability/edema can be assessed noninvasively by MRI and can be observed at the ultrastructural level as gaps between adjacent endothelial cells. Many of these gaps contain activated platelets adhering to exposed basement membrane, reducing vessel patency. Following MI, genetic o...

    A 3-month-old male child underwent uneventful inguinal herniotomy under general anesthesia. After extubation, airway obstruction followed by pulmonary edema appeared for which the baby was reintubated and ventilated. The baby made a complete recovery and extubated after about 2 h. A post-operative computed tomography scan revealed a posterior mediastinal cystic mass abutting the tracheal bifurcation. Presumably, extrinsic compression by the mass on the tracheal bifurcation led to the development of negative pressure pulmonary edema.

    2015-03-01

    The execution and interpretation of neonatal EEG adheres to strict and specific criteria related to this very early age. In preterm newborns, the dedicated healthcare staff needs to respect EEG indications and chronology of EEG recordings in order to diagnose and manage various pathologies, and use EEG in addition to cerebral imaging. EEG analysis focuses on a global vision of the recording according to the neonate's state of alertness and various age-related patterns. Monitoring of continuous conventional EEG and simplified EEG signal processing can help screen for seizures and monitor the effect of antiepileptic treatment, as well as appreciating changes in EEG background activity, for diagnostic and prognostic purposes. EEG reports should be highly explanatory to meet the expectations of the physician's clinical request.

    We describe, to our knowledge, the first case of progressive neonatal liver failure due to neonatal haemochromatosis (NH) occurring in an infant with a gastroschisis and review the literature regarding these two conditions. A 1,665 g male infant with antenatally diagnosed gastroschisis was born with a severe coagulopathy, anaemia, thrombocytopenia, hypoglycaemia and jaundice. He developed progressive liver failure, complicated by necrotising enterocolitis. Serum ferritin was elevated at 1,459 microg/L. He died on day 40 and a limited post-mortem examination confirmed significant hepatic siderosis with fibrosis and cholestasis, and siderosis of the pancreas. Although no genetic aetiology for gastroschisis has been identified, an occasional inherited tendency has been observed. There is also evidence to support an autosomal recessive inheritance in NH.

    Full Text Available Durante o curso da hanseníase, o edema comumente descrito como um sintoma de estados reacionais, pode ocorrer. Tanto o diagnóstico como a terapêutica adequada são, freqüentemente, difíceis de conseguir e assim podem acarretar permanente dano aos membros inferiores. Em um ano de acompanhamento, pacientes hansenianos - 10 multibacilares e 1 paucibacilar -, que foram submetidos a um protocolo clínico para o diagnóstico e classificação histopatológica, apresentaram clinicamente edema, localizado ou sistêmico. Entre estes pacientes, cinco apresentaram simultaneamente outros sintomas de reação, 4 foram classificados como reação Tipo I e um como reação tipo II. Por outro lado, três pacientes não apresentaram reação no momento do diagnóstico, mas desenvolveram alguns aspectos de reação posteriormente (2 tiveram neurite e um teve reação tipo I. Os edemas observados precedendo ou associados a quadros reacionais apresentaram ótima resposta clínica às drogas de ação anti-inflamatória (corticóide, talidomida e pentoxifilina utilizadas para o tratamento dos estados reacionais, na ausência de qualquer outro tratamento normalmente usado para edema. Embora necessitem ser confirmados por estudos controlados, estes dados sugerem fortemente que mecanismos imunológicos estejam envolvidos na fisiopatologia dos edemas na hanseníase.Edema, which is commonly described as a symptom of reactional states, may occur during the course of leprosy. Both diagnosis and adequate treatment measures are often difficult to achieve and failure to do so may result in permanent damage to the lower limbs. In a one-year follow-up study of leprosy patients - ten multibacillary and one paucibacillary - who had been submitted to a clinical protocol for diagnosis and pathological classification, a clinical pattern of localized and/or systemic edema was observed. Among these patients, five simultaneously presented other symptoms related to reactional

    Full Text Available Arie Franco, Kristopher Neal Lewis Department of Radiology, Medical College of Georgia at Georgia Regents University, Augusta, GA, USA Abstract: Ultrasound is the most common imaging tool used in the neonatal intensive care unit. It is portable, readily available, and can be used at bedside. It is the least expensive cross sectional imaging modality and the safest imaging device used in the pediatric population due to its lack of ionizing radiation. There are well established indications for cranial ultrasound in many neonatal patient groups including preterm infants and term infants with birth asphyxia, seizures, congenital infections, etc. Cranial ultrasound is performed with basic grayscale imaging, using a linear array or sector transducer via the anterior fontanel in the coronal and sagittal planes. Additional images can be obtained through the posterior fontanel in preterm newborns. The mastoid fontanel can be used for assessment of the posterior fossa. Doppler images may be obtained for screening of the vascular structures. The normal sonographic neonatal cranial anatomy and normal variants are discussed. The most common pathological findings in preterm newborns, such as germinal matrix-intraventricular hemorrhage and periventricular leukomalacia, are described as well as congenital abnormalities such as holoprosencephaly and agenesis of the corpus callosum. New advances in sonographic equipment enable high-resolution and three-dimensional images, which facilitate obtaining very accurate measurements of various anatomic structures such as the ventricles, the corpus callosum, and the cerebellar vermis. Limited studies have been performed to predict that longitudinal measurements of these anatomic structures might predict the clinical outcome of high-risk preterm newborns. Hemodynamic Doppler studies may offer the potential for early intervention and treatment to counter the hazards of developmental delay and a moribund clinical outcome

Methods: This is a retrospective case series of patients with cystoid macular edema managed with a topical combination of strong steroid (difluprednate, NSAID, and carbonic anhydrase inhibitor drops. The patients were followed with optical coherence tomography and fluorescein angiography. Results: In our six cases, resolution of the cystic edema with improvement in visual acuity was achieved with the use of a combination cocktail of drops. Leakage on fluorescein angiography and cystic edema on optical coherence tomography both responded to treatment with the topical cocktail of drops. Conclusion: A topical cocktail of strong steroid, NSAID, and carbonic anhydrase inhibitor drops are effective for managing cystoid macular edema. Further studies comparing this combination with more invasive treatments should be undertaken to determine the efficacy of this cocktail over other treatment options.

    Pulmonary edema resulting from high pulmonary venous pressure (PVP) is a major cause of morbidity and mortality in heart failure (HF) patients, but current treatment options demonstrate substantial limitations. Recent evidence from rodent lungs suggests that PVP-induced edema is driven by activation of pulmonary capillary endothelial transient receptor potential vanilloid 4 (TRPV4) channels. To examine the therapeutic potential of this mechanism, we evaluated TRPV4 expression in human congestive HF lungs and developed small-molecule TRPV4 channel blockers for testing in animal models of HF. TRPV4 immunolabeling of human lung sections demonstrated expression of TRPV4 in the pulmonary vasculature that was enhanced in sections from HF patients compared to controls. GSK2193874 was identified as a selective, orally active TRPV4 blocker that inhibits Ca(2+) influx through recombinant TRPV4 channels and native endothelial TRPV4 currents. In isolated rodent and canine lungs, TRPV4 blockade prevented the increased vascular permeability and resultant pulmonary edema associated with elevated PVP. Furthermore, in both acute and chronic HF models, GSK2193874 pretreatment inhibited the formation of pulmonary edema and enhanced arterial oxygenation. Finally, GSK2193874 treatment resolved pulmonary edema already established by myocardial infarction in mice. These findings identify a crucial role for TRPV4 in the formation of HF-induced pulmonary edema and suggest that TRPV4 blockade is a potential therapeutic strategy for HF patients.

    Full Text Available OBJECTIVE: Determine the prevalence of postural edema and investigate whether working posture - sitting down or standing up - affect its frequency. METHODS: Sixteen traffic control agents were assessed by water displacement volumetry and the results were analyzed in two groups, depending on working posture. Those who worked standing up for more than 4 hours were allocated to the SU group and those who worked sitting down for more than 4 hours were allocated to the SD group. Each worker was assessed before and after their working shift for three consecutive days. Data were analyzed using ANOVA and the test of equality of two proportions. The significance level was set at p ≤ 0.05. The assessment showed that members of both groups had postural edema of the lower extremities (p ≤ 0.001. RESULTS: When the frequency of postural edema was compared across groups, a trend was observed for greater edema formation in the SU group than in the SD group, although without statistically significant difference. CONCLUSION: It was concluded that traffic control agents suffer postural edema after 4 hours working in either of the postures investigated although with a predominance of edema formation among those who work standing up.

    Full Text Available Introduction. Gyrate atrophy is a rare genetical metabolic disorder affecting vision. Here, we report a 9-year-old boy with gyrate atrophy associated with bilateral macular edema at the time of diagnosis and the effect of long term metabolic control on macular edema. Case Presentation. A 9-year-old boy presented with a complaint of low visual acuity (best corrected visual acuity: 20/80 in both eyes, refractive error: −12.00 D. Dilated fundus examination revealed multiple bilateral, sharply defined, and scalloped chorioretinal atrophy areas in the midperipheral and peripheral zone. Spectral-domain optical coherence tomography revealed bilateral cystoid macular edema in both eyes. Serum ornithine level was high (622 μmol/L. An arginine-restricted diet reduced serum ornithine level (55 μmol/L. However, visual findings including macular edema remained unchanged in 2 years of follow-up. Conclusion. Arginine-restricted diet did not improve macular edema in our patient with gyrate atrophy. A more comprehensive understanding of the underlying factors for macular edema will lead to the development of effective therapies.

    To describe the MR findings of bone marrow edema syndrome (BMES) of the foot and its evolution at 1 year follow-up.Design and patients Twenty-five of 32 patients with disabling foot and ankle pain unrelated to trauma diagnosed as BMES when MR imaging demonstrated a bone marrow edema pattern in one or more bones without any radiological or underlying clinical cause, were re-evaluated by MR imaging 1 year later. On the initial MR examinations an average of 4.7 individual bones were involved by bone marrow edema. Soft tissue edema was present in every patient and joint effusion in 10 patients. MR imaging at 1 year showed resolution of bone edema in 18 patients (72%), partial improvement in five (20%) and no improvement in two (8%). Six patients (24%) developed similar symptoms in the other foot during follow-up. Ten of 17 available plain radiographs showed some loss of radiodensity. Further bone marrow edema developed in bones of the same foot that were initially normal, or in uninvolved distant bone marrow areas in the same affected bone, in six of seven patients on follow-up MR imaging. The evolution of the MR findings of BMES of the foot is to complete resolution or partial improvement at 1 year in the majority of cases. Migration to the other foot occurs in up to a quarter of patients. (orig.)

    Brain edema due to venous thrombosis following stereotactic radiosurgery for a cerebral arteriovenous malformation (AVM) has rarely been reported. We report a patient with a large AVM in the eloquent area, and brain edema developed in this area after repeat Gamma knife stereotactic radiosurgery (GKRS). An 18-year-old female presented with a 4-year-history of persistent headache. Magnetic resonance imaging and transfemoral carotid angiogram revealed a high-flow large AVM in the left parieto-occipital area. Brain edema developed and aggravated patient's symptoms after time-staged GKRS. The cause of edema was thought to be the failure of the surrounding venous channels to drain the venous flow from the normal brain and the drainage was hampered by the persistent shunt flow from the AVM, which was due to the thrombosis of one huge draining vein of the AVM. The microsurgical resection of the AVM nidus eliminated shunt flow and completely normalized the brain edema. Microsurgical resection of the AVM nidus completely normalized the brain edema due to thrombosis of a draining vein of an AVM develops after SRS. PMID:27574486

  14. Clinical correlates of the spectrum of lung microvascular injury in human noncardiac edema

    International Nuclear Information System (INIS)

    Researchers measured the clearance from blood to pulmonary edema fluid of a small molecular researchersight hydrophilic radiotracer, Indium-111-DTPA (In-DTPA) and a larger molecular researchrsight radiotracer, Iodine-125-HSA (I-HSA), in patients with pulmonary edema on either a cardiac or noncardiac (permeability) basis. In previous investigations, researchers had noted an apparent relationship between the magnitude of clearance of I-HSA across the alveolocapillary membrane and the severity of noncardiac pulmonary edema. In this study, researchers were able to distinguish at least 2 distinct groups of patients with noncardiac pulmonary edema. Patients with the greatest damage to the alveolo-capillary exchanging membrane, defined by the flux of I-HSA from blood to edema fluid, were significantly differentiated from those with a lesser microvascular injury on the basis of higher mean heart rate (HR), temperature, cardiac index (CI), pulmonary artery pressures, right ventricular stroke work index (RVSWI), and a lower mean total white blood cell count (WBC), among others. Therefore, noncardiac pulmonary edema is characterized by a spectrum of permeability injury to the pulmonary microvasculature which seems to parallel other measurable indices of the severity of the systemic response to the illness

    Previous studies demonstrated that exposure to simulated microgravity, head-down tilt (HDT), caused cephalad fluid shift, increased capillary pressure in the head, and produced facial edema and nasal congestion. It is also known that exposure to HDT affects hemodynamics in the brain. Cerebral blood flow (CBF) velocity increases for at least 6 hours after the onset of 6 degrees HDT in humans. Intracranial pressure (ICP) elevates during 6 degrees HDT in humans and monkeys. However, there is little information regarding edema formation in the brain due to HDT except a morphological study reported by Kaplansky and colleagues who showed that perivascular edema occurred in the monkey brain after 7 days of 6 degrees HDT. Thus, it is interesting to examine whether edema formation occurs in the other animal model for simulation of microgravity, since several factors such as the duration of HDT, angle of HDT, and species difference may affect the result. In the present study, formation of brain edema was investigated by histological examinations in rabbits exposed to 45 degrees HDT for 2 days or 8 days. We hypothesized that HDT causes brain edema which can be demonstrated as extravasation of plasma constituents and histological changes.

    2003-01-01

    Full Text Available PURPOSE: This work had the objective of verifying the validity of using computerized morphometry as a method of quantitative analysis of the interference of edema in scar formation following colon anastomosis. METHODS: Forty-five adult female Wistar rats were utilized, divided into three groups of 15 animals according to whether sacrifice was performed on the first, second or seventh postoperative day. Each group was subdivided into a main group consisting of 10 animals, and a control group consisting of five animals. In the main group, in addition to the quantitative computerized morphometric analysis of the edema in the submucosal layer, the resistance of the colon anastomosis to bursting strength was verified. In the control group, edema quantification was studied alone. RESULTS: The results found via the computerized morphometry method showed that there is a 7% decrease in the presence of edema during the first postoperative week. They confirmed that there is an inverse statistically significant relationship (p< 0.001 between edema presence and the resistance of the anastomosis to bursting strength. CONCLUSION: The use of computerized morphometry is a reliable, fast, objective and low-cost methodology for the quantification of edema in colon anastomoses.
