    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

    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. This review focuses on how the maladapted astrocytic plasticity in ischemic stroke plays the central role in the brain edema formation. PMID:27242440

    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 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.

    Full Text Available PURPOSE: This study investigates the differential aqueous concentrations of interleukin 6, 8, 1β (IL-6, IL-8, IL-1β, respectively, serum amyloid A (SAA, transforming growth factor (TGF-β, basic fibroblast growth factor (bFGF, and vascular endothelial growth factor (VEGF in eyes with macular edema as a result of a branch retinal vein occlusion (BRVO or central retinal vein occlusion (CRVO. PRINCIPAL FINDINGS: Significantly higher concentrations of IL-6, IL-8, IL-1β, TGF-β, bFGF, SAA, and VEGF were found in the aqueous humor of CRVO and BRVO patients than in the aqueous humor of control patients. A significant correlation was observed between the concentration of bFGF and the inner central macular thickness (CMT of BRVO patients (r = 0.688; P = 0.02. A significant correlation was observed between the concentration of SAA and both the full and outer CMT of the ischemic group (r = 0.545 and 0.683, respectively; P = 0.04 and 0.01, respectively. In the non-ischemic group, the level of IL-6 was significantly associated with inner CMT (r = 0.560; P = 0.03. The full and outer CMT was significantly reduced in CRVO patients when compared with BRVO patients (P = 0.02 and 0.02, respectively after injection of intravitreal bevacizumab (IVB at 4 weeks. SIGNIFICANCE: Serum amyloid A as a major protein involved in the acute and chronic stages of inflammation, and IL-6 and bFGF were significantly associated with the extent of macular edema in patients with RVO. Besides VEGF, other inflammatory cytokines and angiogenesic factors may be associated with RVO. This finding may have implications for the medical treatment of RVO.

    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.

    2016-04-01

    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

  7. 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.

Plain chest radiographs of 77 patients, who were clinically confirmed as having pulmonary edema, were retrospectively reviewed. The patients were classified into three groups : group 1 (cardiogenic edema : n = 35), group 2 (renal pulmonary edema : n = 16) and group 3 (permeability edema : n = 26). We analyzed the radiologic findings of air bronchogram, heart size, peribronchial cuffing, septal line, pleural effusion, vascular pedicle width, pulmonary blood flow distribution and distribution of pulmonary edema. In a search for radiologic findings which would help in the differentiation of these three etiologies, each finding was assessed. Cardiogenic and renal pulmonary edema showed overlapping radiologic findings, except for pulmonary blood flow distribution. In cardiogenic pulmonary edema (n=35), cardiomegaly (n=29), peribronchial cuffing (n=29), inverted pulmonary blood flow distribution (n=21) and basal distribution of edema (n=20) were common. In renal pulmonary edema (n=16), cardiomegaly (n=15), balanced blood flow distribution (n=12), and central (n=9) or basal distribution of edema (n=7) were common. Permeability edema (n=26) showed different findings. Air bronchogram (n=25), normal blood flow distribution (n=14) and peripheral distribution of edema (n=21) were frequent findings, while cardiomegaly (n=7), peribronchial cuffing (n=7) and septal line (n=5) were observed in only a few cases. On plain chest radiograph, permeability edema can be differentiated from cardiogenic or renal pulmonary edema. The radiographic findings which most reliably differentiated these two etiologies were air bronchogram, distribution of pulmonary edema, peribronchial cuffing and heart size. Only blood flow distribution was useful for radiographic differentiation of cardiogenic and renal edema

    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

    2006-06-01

    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.

    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.

Inflammatory, diabetic, post-cataract, and macular edema due to age-related macular degeneration is described. The role of chronic inflammation and hypoxia and direct macular traction is evaluated in each case according to different views from the literature. The different diagnostic methods for evaluating the edema are described. Special attention is given to fluoroangiography and the most modern methods of macula examination, such as ocular coherence tomography and multifocal electroretinography. Finally, we discuss the treatment of cystoid macular edema in relation to its etiology. In this chapter we briefly refer to the therapeutic value of laser treatment especially in diabetic maculopathy or vitrectomy in some selected cases. Our paper is focused mainly on recent therapeutic treatment with intravitreal injection of triamcinolone acetonide and anti-VEGF factors like bevacizumab (Avastin, ranibizumab (Lucentis, pegaptamid (Macugen, and others. The goal of this paper is to review the current status of this treatment for macular edema due to diabetic maculopathy, central retinal vein occlusion and post-cataract surgery. For this reason the results of recent multicenter clinical trials are quoted, as also our experience on the use of intravitreal injections of anti-VEGF factors and we discuss its value in clinical practice.Keywords: cystoid macular edema, anti-VEGF, fluoroangiography, OCT, multifocal electroretinography

    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.

  7. Importance of Central Retinal Sensitivity for Prediction of Visual Acuity after Intravitreal Bevacizumb in Eyes with Macular Edema Associated with Branch Retinal Vein Occlusion.

    Full Text Available To determine whether the baseline retinal sensitivity can predict the best-corrected visual acuity (BCVA at 1 month after intravitreal bevacizumab (IVB in eyes with macular edema (ME associated with a branch retinal vein occlusion (BRVO.We evaluated 16 eyes of 16 patients who had ME associated with a BRVO. The mean ± standard deviation age was 69.1 ± 8.9 years, and all had a single IVB injection. The BCVA, central macular thickness (CMT, integrity of the ellipsoid zone (EZ of the photoreceptors, and retinal sensitivity were determined before (baseline and at 1 day, 1 week, and 1 month following the IVB. The average threshold retinal sensitivity (AT within the central 10° was determined by Macular Integrity Assessment. The correlations between the BCVA at 1 month and the CMT, integrity of the EZ, and AT at each visit were determined.One month after IVB, the BCVA improved significantly from 0.56 ± 0.27 logMAR units to 0.32 ± 0.28 logMAR units, and the CMT from 611.4 ± 209.3 μm to 258.7 ± 64.0 μm (P <0.05. The AT improved significantly from 17.9 ± 5.3 dB to 21.2 ± 5.0 dB (P <0.05. At 1 day after the treatment, both the integrity of the EZ (r = 0.59 and the retinal sensitivity (r = 0.76 were moderately correlated with the BCVA at 1 month.These results indicate that both the integrity of the EZ and the AT at 1 day after the IVB can predict the BCVA after treatment for ME associated with BRVO. There is a possibility that these parameters will predict the effectiveness of IVB for each case.

    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.

    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

  12. 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

    2014-01-01

    Background The treatment of central diabetes insipidus (DI) with desmopressin in the neonatal period is challenging because of the significant risk of hyponatremia with this agent. The fixed anti-diuresis action of desmopressin and the obligate high fluid intake with milk feeds lead to considerable risk of water intoxication and hyponatremia. To reduce this risk, thiazide diuretics, part of the treatment of nephrogenic DI, were used in conjunction with low renal solute feed and were effective...

    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.

    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).

    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.

  14. 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

We retrospectively analyzed simple chest and abdominal radiographs, and brain sonograms in 36 newborn infants (preterm : term=23 :13). With neonatal sepsis diagnosed by blood culture and clinical manifestations. Pulmonary parenchymal infiltrate excluding respiratory distress syndrome and pulmonary edema or atelectasis was found in 22 infants (61%). Paralytic ileus, hepatosplenomegaly, and necrotizing enterocolitis were present in 18(50%), 9(25%), and 1(3%) infants, respectively, while skeletal changes suggesting osteomyelitis were found in three. Brain sonography was performed in 29 infants and in four, abnormalities were seen ; these comprised three germinal matrix hemorrhages and one intraparenchymal hemorrhage. In six patients(17%) radiologic examinations revealed no abnormality. In patients with neonatal sepsis, pulmonary infiltrates and paralytic ileus were common abnormalities. Although these were nonspecific, radiologic findings may be used to supplement clinical and laboratory findings in diagnosing neonatal sepsis and planning its treatment

    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.

    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.

    Full Text Available The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. 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.

    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.

  11. Neonatal neoplasms

    International Nuclear Information System (INIS)

    Purpose: To describe neoplasms diagnosed in children ≤ 28 days of age along with their treatment, associated congenital anomalies, and the long-term consequences of the diagnoses and treatments. Methods and Materials: Utilizing autopsy records, a computerized tumor registry, and medical records, we identified patients and stillborns at Duke University Medical Center (DUMC) diagnosed with neoplasms at ≤ 28 days of age between 1930 and 1998. Results: Twenty-three neonates with neoplasms were identified. There were 7 males (30%) and 16 females (70%). Follow-up of survivors ranged from 4 months to 27 years (mean 9 years). The 20 patients identified via the computerized registry system for 1980-1998 constitute 2% (20/925) of all neoplasms seen in patients ≤ 16 years of age over this same time period at DUMC. The histologic diagnoses were teratoma/germ cell tumor (n = 8, 35%), neuroblastoma (n = 5, 22%), retinoblastoma (n = 4, 17%), primary central nervous system (CNS) tumor (n = 3, 13%), and one case each of rhabdomyosarcoma, glossal glial choristoma, and hemangioma in the setting of Kasabach-Merritt Syndrome. Of the eight teratoma/germ cell tumor patients, 6 were female (75%) and 2 male (25%). There was one malignant germ cell tumor, 2 immature teratomas, and 5 teratomas. Two of the seven patients with immature teratomas or teratoma were long-term survivors following surgery. The one patient with malignant germ cell tumor, treated with surgery and chemotherapy, died. Associated anomalies were imperforate anus, congenital absence of a limb, left ventricular hypertrophy, fusion or absence of toes, coarctation of the aorta, and pulmonary valve dysplasia. Of the five children with neuroblastoma, 4 were female. INSS Stages were 1 (n = 1), 2A (n = 1), 3 (n = 1), and 4S (n = 2). Two were treated with surgery + chemotherapy + radiotherapy; two with surgery + chemotherapy; and one with surgery alone. Four children are long-term survivors. Associated congenital anomalies

    2016-01-01

    Acute Hemorrhagic Edema of Infancy is a small vessel leucocytoclastic vasculitis affecting young infants. It is characterized by large, target-like, macular to purpuric plaques predominantly affecting the face, ear lobes and extremities. Non-pitting edema of the distal extremities and low-grade fever may also be present. Extra-cutaneous involvement is very rare. Although the lesions have a dramatic onset in a twenty-four to forty-eight hour period, usually the child has a non-toxic appearance. In most cases there are no changes in laboratory parameters. The cutaneous biopsy reveals an inflammatory perivascular infiltrate. It is a benign and auto-limited disease, with complete resolution within two to three weeks leaving no sequelae in the majority of cases. No recurrences are described. We report a case of a 42-day old girl admitted at our hospital with Acute Hemorrhagic Edema of Infancy. PMID:26808448

  13. Bone marrow edema of the knee joint

    International Nuclear Information System (INIS)

    Bone marrow edema of the knee joint is a frequent clinical picture in MR diagnostics. It can be accompanied by symptoms and pain in the joint. Diseases that are associated with bone marrow edema can be classified into different groups. Group 1 includes vascular ischemic bone marrow edema with osteonecrosis (synonyms: SONK or Ahlbaeck's disease), osteochondrosis dissecans, and bone marrow edema syndrome. Group 2 comprises traumatic or mechanical bone marrow edema. Group 3 encompasses reactive bone marrow edemas such as those occurring in gonarthrosis, postoperative bone marrow edemas, and reactive edemas in tumors or tumorlike diseases. Evidence for bone marrow edema is effectively provided by MRI, but purely morphological MR information is often unspecific so that anamnestic and clinical details are necessary in most cases for definitive disease classification.

    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.

    Full Text Available Macular edema is a significant cause of vision loss in patients with central retinal vein occlusions and branch retinal vein occlusions. Vascular endothelial growth factor (VEGF appears to be a key factor in the pathogenesis of this disease. Anti-VEGF therapy, such as intravitreal ranibizumab provides an effective treatment against vision-threatening macular edema. We report three patients of retinal vein occlusion with macular edema who demonstrated overnight resolution of macular edema following treatment with intravitreal ranibizumab (0.5 mg. 3D optical coherence tomography (Optovue was used as a tool for comparison of the macular thickness before and after treatment. The significant reductions in the central foveal thickness demonstrated in these patients one night after intravitreal injections could have significant influence on modifying current treatment protocols. Early treatment of macular edema related to retinal venous occlusive disease with anti-VEGF injections could result in faster visual rehabilitation in these patients.

    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.

    Hereditary angioneurotic edema results from the deficiency of C1-esterase inhibitor. The clinical picture of this autosomal dominant disorder is characterized by recurrent attacks of edema formation in the subcutis and/or the submucosa. The clinical records of 21 children with established hereditary angioneurotic edema were reviewed. Follow-up care included laboratory check-ups and abdominal ultrasound. Clinical manifestations of the disease first occurred in 2.5 to 12 years of age. Mechanical trauma was the most common precipitating factor. Pedigree-analysis revealed 19 patients with afflicted relatives. Long-term prophylaxis was initiated with tranexamic acid and danazol in 10 cases; 2 children required short-term prophylaxis. Therapy improved serum complement parameters significantly and reduced the frequency and severity of clinical manifestations. Acute, life-threatening edematous attacks were treated by the administration of C1-inhibitor concentrate, which achieved the resolution of the edema within several hours. Abdominal ultrasonography performed during the attack invariably demonstrated transitory ascites that resolved spontaneously after treatment. Adequate prophylaxis and follow-up care can spare pediatric patients from edematous attacks. Undesirable adverse effects can be avoided and the patient's quality of life can be enhanced considerably by administering the lowest effective drug dose. PMID:11143287

    Objective: To determine the association between pre-operative and intra-operative factors leading to transient corneal edema after phacoemulsification. Study Design: Cohort study. Place and Duration of Study: Department of Ophthalmology, Shifa Foundation Community Health Centre, Islamabad, from October 2011 to September 2012. Methodology: Patients undergoing phacoemulsification and Intraocular Lens (IOL) implantation were enrolled in the study using consecutive non-probability sampling. Pre-operative risk factors including peripheral corneal degenerations, the type and density of cataract were documented. Surgical risk factors included the incision site, the type of intraocular lens, the phacotechnique and the phacopower time. Postoperatively the patients were assessed for corneal clarity and the degree of striate keratopathy. Statistical analysis was done using SPSS version 17. Results: There were 43% male and 57% female patients (n = 182). Mean age was 58.92 ± 13.00 years (median and mode-60 years). Factors which increased the risk of transient corneal edema after phacoemulsification included hypertension (p = 0.022), dense nuclear cataracts (p=0.006), divide and conquer technique (p = 0.008), duration of phacopower use (p < 0.001) and peripheral corneal degenerations (p < 0.001). Conclusion: Patients with peripheral corneal degenerations and dense nuclear cataracts had significantly higher rates of postoperative corneal edema. Use of phaco-chop technique and less phaco-power time helps in decreasing corneal edema. (author)

    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

    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. PMID:26997733

    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 vas...

    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.

  10. 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.

    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

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.

  16. Pathogenesis of optic disc edema in raised intracranial pressure.

    2016-01-01

    Optic disc edema in raised intracranial pressure was first described in 1853. Ever since, there has been a plethora of controversial hypotheses to explain its pathogenesis. I have explored the subject comprehensively by doing basic, experimental and clinical studies. My objective was to investigate the fundamentals of the subject, to test the validity of the previous theories, and finally, based on all these studies, to find a logical explanation for the pathogenesis. My studies included the following issues pertinent to the pathogenesis of optic disc edema in raised intracranial pressure: the anatomy and blood supply of the optic nerve, the roles of the sheath of the optic nerve, of the centripetal flow of fluids along the optic nerve, of compression of the central retinal vein, and of acute intracranial hypertension and its associated effects. I found that, contrary to some previous claims, an acute rise of intracranial pressure was not quickly followed by production of optic disc edema. Then, in rhesus monkeys, I produced experimentally chronic intracranial hypertension by slowly increasing in size space-occupying lesions, in different parts of the brain. Those produced raised cerebrospinal fluid pressure (CSFP) and optic disc edema, identical to those seen in patients with elevated CSFP. Having achieved that, I investigated various aspects of optic disc edema by ophthalmoscopy, stereoscopic color fundus photography and fluorescein fundus angiography, and light microscopic, electron microscopic, horseradish peroxidase and axoplasmic transport studies, and evaluated the effect of opening the sheath of the optic nerve on the optic disc edema. This latter study showed that opening the sheath resulted in resolution of optic disc edema on the side of the sheath fenestration, in spite of high intracranial CSFP, proving that a rise of CSFP in the sheath was the essential pre-requisite for the development of optic disc edema. I also investigated optic disc edema with

  18. Radionuclide lymphoscintigraphy in limb edemas

    International Nuclear Information System (INIS)

    Indirect radionuclide lymphoscintigraphy is a safe, non-invasive and physiological method for the assessment of the limb lymphatic system. Colloids as antimony or rhenium sulphide labeled with 99m technetium have been widely used for morphological studies. Quantitative studies involving a continuous count rate monitoring of the injection sites followed by a computer analysis of dynamic image sequences have been a new promising step for an objective measurement of the peripheral lymphatic function. The injection site is always bilateral on the first web space of either the hand or the foot using a small volume (<0.2 mL) of the radiocolloid. This method has been validated on 30 young healthy volunteers and normal values established from a group of 125 upper and 141 lower limbs (normal subjects). The normal results showed a slight but continuous decrease in lymphatic function depending on the age of the subject. In pathological situations, we observed dysfunction of the lymphatic system in pure lymphoedemas or so-called lympho-venous edemas as demonstrated on the 1,182 upper and 2,463 lower limbs tested. The radionuclide lymphoscintigraphy may be helpful in cases of unilateral swollen limbs demonstrating a lymphatic dysfunction on a clinically normal contralateral limb at the first stage of a distal edema which appears within a few weeks or days, in a transient edema phase when normal status and oedema alternate. The lymphoscintigraphy gives objective and reproducible parameters necessary to assess the lymphatic variation under therapy (decongestive physiotherapy, surgery, drugs) and may be useful in the selection of new lympho-tonic treatments. This method is only reflecting the lymphatic function and is unable to appreciate the total lymphatic flow of the limb. Its results only reflect what happens at the injection site and it may be necessary to add a second test using a proximal injection in order to assess the occurrence of lymph nodes not visualized by the

  20. Bone marrow edema in sports: General concepts

    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.

    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.

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.

    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].

    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.

  13. Aquaporin-4 and traumatic brain edema

    2010-01-01

    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.

    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.

  16. Diagnostic imaging in neonatal stroke

    International Nuclear Information System (INIS)

    A cerebral artery infarction is an important differential diagnosis in the newborn with neurological abnormalities. Based on clinical data, its incidence is estimated to be 1 in 4000 newborns. Since the course is often subclinical, the true incidence is probably higher. Diagnosis: Cerebral ultrasound and Doppler sonography as readily available screening tools play a central role in the initial diagnosis of neonatal cerebral infarction. Definitive diagnosis is made by computed tomography or magnetic resonance imaging. Beside symptomatic anticonvulsive therapy, treatment aims at the prevention of secondary ischemic injury. Discussion: Three term infants with different clinical courses of neonatal stroke are presented to sensitize the clinician and the radiologist for this probably underdiagnosed entity. The role of imaging modalities in the diagnosis and follow-up of neonatal cerebral infarction is discussed. (orig.)

    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

    Full Text Available This study describes a patient diagnosed as a case of bipolar affective disorder complaining of bothersome incidence of pedal edema 1 month after the initiation of atypical antipsychotic regimen with risperidone and quetiapine. All hematological and biochemical profiles were found to be normal. On discontinuation of risperidone, the condition remained unresolved even after 2 weeks, and the edema progressed reaching her calves. On tapering the dose of quetiapine, she started showing gradual improvement in edematous condition. Quetiapine was slowly discontinued. No further recurrence of edema occurred, and hence, no further medication changes were implemented. Pedal edema was found to be resolved within weeks of dechallenge of the regimen. Naranjo adverse drug reaction probability scale gave a score of 7 which denotes "probable" adverse drug reaction with quetiapine.

    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.

    2003-01-01

    Neonatal screening (NS) is a medical act in the context of preventive medicine aimed at the early identification of infants affected by certain conditions that threaten their life and long-term health, for which a timely intervention can lead to a significant reduction of morbidity, mortality and associated disabilities. It emerged three decades ago in the context of prevention of mental retardation. Since then, around 600 inborn metabolic disorders have been described and technological progress has been impressive; nevertheless only around 5% of the disorders have been the object of NS. The most frequently cited reasons for the limitation are low prevalence and the lack of treatment. The tandem mass spectrometry has come in place in recent years across the globe, expanding NS to include several disorders of intermediary metabolism. This has shown, in addition to a prevalence much higher than previously thought, the benefits of early detection. The present work is a review of NS, not only from the point of view of technological/medical achievements, but also considering other factors which will affect specific disease selection, according to the social and organizational infrastructure that may expand the borders of NS.

    2009-12-01

    Despite advances in the care of infants, there remain many newborns whose medical conditions are incompatible with sustained life. At times, healthcare providers and parents may agree that prolonging life is not an appropriate goal of care, and they may redirect treatment to alleviate suffering. While pediatric palliative treatment protocols are gaining greater acceptance, there remain some children whose suffering is unrelenting despite maximal efforts. Due to the realization that some infants suffer unbearably (ie, the burdens of suffering outweigh the benefits of life), the Dutch have developed a protocol for euthanizing these newborns.

    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 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.

  1. Pharmacological intravitreal treatment for macular edema in branch retinal vein occlusion: Three-month results

    Full Text Available Introduction. Macular edema is the main cause of visual loss in patients with branch retinal vein occlusion. Macular edema is initially reversible, but over time, permanent loss of vision occurs from structural damage to the macula. For this reason, there is a need for more rapid and effective treatments than laser photocoagulation which has been established as a gold standard. There are several pharmacologic agents which have changed the management of macular edema. Material and Methods. Twenty eyes of 20 consecutive patients of the Department of Eye Diseases, Clinical Center of Vojvodina, in Novi Sad, were enrolled in this prospective, randomized and consecutive study conducted from January 2012 to January 2013. The patients were randomly assigned into two treatment groups, and they were given an intravitreal injection of bevacizumab 1.25 mg/0.05 mL (Avastin®, or triamcinolone acetonid injection 4 mg/0.1mL (Kenalog®. Reinjections were performed according to the following retreatment criteria a loss of visual acuity or increase in central retinal thickness. Results. Both intravitreal bevacizumab and triamcinolonacetonid were very effective in reducing macular edema and improving visual acuity in the eyes with macular edema secondary to retinal vein occlusion. The effect of the treatment was more pronounced if it started early after the onset of macular edema. The reported temporary effects of intravitreal triamcinolon- acetonide and bevacizumab could be explained by their clearance from the eye. Conclusion. The short-term results of our clinical trial showed that pharmacological intravitreal agents, such as bevacizumab and triamcinolon-acetonid, lead to rapid resolution of macular edema and significant improvement of visual acuity.

  2. Ascorbic acid repletion: A possible therapy for diabetic macular edema?

    Macular edema poses a significant risk for visual loss in persons with diabetic retinopathy. It occurs when plasma constituents and fluid leak out of damaged retinal microvasculature in the area of the macula, causing loss of central vision. Apoptotic loss of pericytes surrounding capillaries is perhaps the earliest feature of diabetic vascular damage in the macula, which is also associated with dysfunction of the endothelium and loss of the otherwise very tight endothelial permeability barrier. Increased oxidative stress is a key feature of damage to both cell types, mediated by excess superoxide from glucose-induced increases in mitochondrial metabolism, as well as by activation of the receptor for advanced glycation end products (RAGE). The latter in turn activates multiple pathways, some of which lead to increased oxidative stress, such as those involving NF-ĸB, NADPH oxidase, and endothelial nitric oxide synthase. Such cellular oxidative stress is associated with low cellular and plasma ascorbic acid levels in many subjects with diabetes in poor glycemic control. Whether repletion of low ascorbate in retinal endothelium and pericytes might help to prevent diabetic macular edema is unknown. However, cell culture studies show that the vitamin prevents high-glucose and RAGE-induced apoptosis in both cell types, that it preserves nitric oxide generated by endothelial cells, and that it tightens the leaky endothelial permeability barrier. Although these findings need to be confirmed in pre-clinical animal studies, it is worth considering clinical trials to determine whether adequate ascorbate repletion is possible and whether it might help to delay or even reverse early diabetic macular edema.

  4. 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

    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. PMID:24147200

  7. Vasogenic edema characterizes pediatric acute disseminated encephalomyelitis

    International Nuclear Information System (INIS)

    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 10-3 and 0.81 ± 0.09 x 10-3 mm/s2, 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.)

    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.

    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

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

    Full Text Available To report a patient with Danon retinopathy with cystoid macular edema treated with topical dorzolamide 2% eye drops and oral acetazolamide. 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.

  8. MR imaging of edema accompanying benign and malignant bone tumors

    International Nuclear Information System (INIS)

    To evaluate the incidence, quantity, and presentation of intra- and extraosseous edema accompanying benign and malignant primary bone lesions, the magnetic resonance (MR) studies of 63 consecutive patients with histologically proven primary bone tumors were reviewed. MR scans were assessed for the presence and quantity of marrow and soft tissue edema and correlated with preoperative findings, resected specimens and follow-up data. The signal intensity and enhancement of tumor and edema prior to and after intravenous administration (if any) of gadolinium-labled diethylene triamine pentaacetate (Gd-DTPA) was analyzed. Marrow edema was encountered adjacent to 8 of 39 maglinant tumors and 14 of 24 benign lesions. Soft tissue edema was found accompanying 28 of 39 malignancies and 10 of 24 benign disorders. On enhanced T1-weighted MR images tumor and edema were difficult to differentiate. Tumor inhomogeneity made this differentiation easier on T2-weighted sequences. In 36 patients the contrast medium Gd-DTPA was used. Edema was present in 27 of these patients and the respective enhancement of tumor and edema could be compared. Edema always enhanced homogeneously, and in most cases it enhanced to a similar degree as or more than tumor. Marrow and, more specifically, soft tissue edema is a frequent finding adjacent to primary bone tumors. The mere presence and quantity of marrow and soft tissue edema are unreliable indicators of the biologic potential of a lesion. Unenhanced MR scans cannot always differentiate between tumor and edema, but the administration of Gd-DTPA is of assistance in differentiating tumor from edema. Awareness of marrow and/or soft tissue edema adjacent to bone lesions is of importance because edema can be a pitfall in the diagnostic work-up and staging prior to biopsy or surgery. (orig.)

    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.

    2016-04-01

    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.

    Every year thousands of ski, trekking or climbing fans travel to the mountains where they stay at the altitude of more than 2500-3000m above sea level or climb mountain peaks, often exceeding 7000-8000m. High mountain climbers are at a serious risk from the effects of adverse environmental conditions prevailing at higher elevations. They may experience health problems resulting from hypotension, hypoxia or exposure to low temperatures; the severity of those conditions is largely dependent on elevation, time of exposure as well as the rate of ascent and descent. A disease which poses a direct threat to the lives of mountain climbers is high altitude pulmonary edema (HAPE). It is a non-cardiogenic pulmonary edema which typically occurs in rapidly climbing unacclimatized lowlanders usually within 2-4 days of ascent above 2500-3000m. It is the most common cause of death resulting from the exposure to high altitude. The risk of HAPE rises with increased altitude and faster ascent. HAPE incidence ranges from an estimated 0.01% to 15.5%. Climbers with a previous history of HAPE, who ascent rapidly above 4500m have a 60% chance of illness recurrence. The aim of this article was to present the relevant details concerning epidemiology, pathophysiology, clinical symptoms, prevention, and treatment of high altitude pulmonary edema among climbers in the mountain environment.

    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.

  16. Radiological diagnosis of pulmonary edema in chronic renal failure

    International Nuclear Information System (INIS)

    Pulmonary edema has been revealed in 132 patients (51.6 %) during radiologic examination of 256 patients with chronic renal failure. The performance of anterio-posterior chest radiographs was in most cases necessary and quite sufficient for making diagnostic conclusions. Follow up study of patients with pulmonary edema and analysis of radiologic picture of the alterations permitted physicians to distinguish approximately 3 stages of the process development, which transit from one into another. Stage 1 involves early disorders and prodromes of pulmonary edema; Stage 2 interstitial lung edema; Stage 3 alveolar edema. The circulation enforcement of the upper lobar vessels has been the main feature of stage 1. Radiogramometry provided additional information for the pulmonary edema diagnosis. For instance, cardioradiometric data are useful for pulmonary edema diagnosis and evidence in favour of its close connection with heart disorders

    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

    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.

    To evaluate the role of MR imaging in the diagnosis of edema, various types of edema were examined with MR imaging. MR imaging of edematous limbs was performed on 60 patients (lymphatic edema 48, nonlymphatic edema 12) using. T1-and T2-weighted spin-echo and shot inversion time inversion recovery sequences. Thickness and signal intensity of the cutis, subcutis and subfascia were evaluated in the images. In all 48 cases with lymphatic edema, trabecular structures suggesting dilated collateral lymphatic vessels were observed in the swollen subcutis. Two cases with nephrotic syndrome showed similar findings. In 6 cases with venous edema, fatty intensity was found in the subfascia. In the remaining 4 cases, the subcutis exhibited only water intensity. MR imaging is a potential contributor to the diagnosis of various edematous diseases. (orig./MG).

  16. 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.

  17. 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.

    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

  5. Hypothyroidism in Filipino neonates

    International Nuclear Information System (INIS)

    Thyroid hormone determination (T4, T3, rT3, TSH) in cord blood of 3,897 newborns was carried out in Metro Manila (non-endemic) and central, Northern and Southern Luzon (endemic for goiter). The objective is to detect congenital hypothyroidism and establish its incidence in new born Filipinos. This was done by radioimmunoassay, using commercial kits from Abbott Laboratories. The results obtained as mean values for non-endemic regions are: T4: 10.96 +- 2.25 ug/dl; T3: 60-64 +- 13.82 ng/dl; rT3: 250.4 +- 64.9 ng/dl; and TSH 5.89 +- 2.58 uU/ml, n=200. Mean values in endemic regions (n = 205) are T4: 9.46 +- 2.18 ug/dl; T3: 67.8 +- 12.05 ng/dl; rT3: 184.3 +- 32.7 ng/dl and TSH: 6.65 +- 3.13 uU/ml. From the above data, nomograms were drawn where the values obtained from each case were plotted. From non-endemic regions 28 positive cases were recalled and in the endemic regions 16 positive cases were also recalled for re-examination but most of them turned out to be false positive. As of now, four positive cases were found in Metro Manila, i.e. 4/2, 441 births and five in endemic regions out of 1,456 births so the incidence of neonatal hypothyroidism is 9/3,897 births. This is 9 times higher than most reports abroad which is about 1/4000 births. (Auth.). 36 refs; 10 tabs; 10 figs

    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.

    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

    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

  19. CT findings in brain edema following the administration of corticosteroids

    International Nuclear Information System (INIS)

    Computed tomography (CT) is the first noninvasive method available for directly visualizing brain edema in man. On CT scans perifocal edema is shown as an area of low density surrounding a lesion. The purpose of this report is to evaluate the effect of corticosteroids on brain edema as seen by CT (HITACHI CT-H 250). Nine patients with brain-tumor and one with brain-abscess were treated with betamethasone for about ten days (dosage started with 12 - 16 mg/day, and tapered). In eight cases, and improvement in the neurological findings was observed. An impressive reduction of peritumoral edema was shown on CT scans in six of these eight cases. There was, however, no significant correlation between the degree of the reduction of edema on CT and that of the improvement in neurological findings. The mode of the CT number in the region of edema did not differ significantly between pre- and post-steroid treatment in the cases showing a recognizable reduction of edema on CT. This failure to change is probably due to the insufficient mechanical accuracy of the CT scanner at the present stage of technology. Through our experiences, it seems that CT is one of the most promising tools for a dynamic study of brain edema in man. (author)

    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.

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.

    1986-12-01

    Full Text Available The role of hyperammonemia in the pathogenesis of cerebral edema was investigated using mongrel dogs to develop a treatment for cerebral edema in acute hepatic failure. Intravenous infusion of ammonium acetate alone into dogs did not induce brain edema, although blood ammonia reached unphysiologically high levels. However, ammonium acetate infusion during mannitol-induced reversible (osmotic opening of the blood-brain barrier (BBB effectively induced cytotoxic brain edema. Pretreatment with a branched-chain amino acid (BCAA; valine, leucine and isoleucine solution prevented an increase in intracranial pressure (ICP and brain water content, and caused a decrease in brain ammonia content and an increase in brain BCAA and glutamic acid. The results suggest that ammonia plays an important role in the pathogenesis of cerebral edema during acute hepatic failure and that BCAAs accelerate ammonia detoxification in the brain.

    Full Text Available Roomasa Channa, Michael Smith, Peter A CampochiaroDepartments of Ophthalmology and Neuroscience, The Johns Hopkins University School of Medicine, Baltimore, MD, USA Abstract: Retinal vein occlusion (RVO is a prevalent retinal vascular disease, second only to diabetic retinopathy. Previously there was no treatment for central retinal vein occlusion (CRVO and patients were simply observed for the development of severe complications, generally resulting in poor visual outcomes. The only treatment for branch vein occlusion (BRVO was grid laser photocoagulation, which reduces edema very slowly and provides benefit in some, but not all patients. Within the past year, clinical trials have demonstrated the effects of three new pharmacologic treatments, ranibizumab, triamcinolone acetonide, and dexamethasone implants. The benefit/risk ratio is best for intraocular injections of ranibizumab, making this first-line therapy for most patients with CRVO or BRVO, while intraocular steroids are likely to play adjunctive roles. Standard care for patients with RVO has changed and will continue to evolve as results with other new agents are revealed.Keywords: vascular endothelial growth factor, triamcinolone acetonide, dexamethosone implant, sustained release, vascular leakage, ischemia

  10. Exercise-Induced Pulmonary Edema in a Triathlon

    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.

    The chemical toxins in smoke and not the heat are responsible for the pulmonary edema of smoke inhalation. We developed a synthetic smoke composed of carbon particles (mean diameter of 4.3 microns) to which toxins known to be in smoke, such as HCl or acrolein, could be added one at a time. We delivered synthetic smoke to dogs for 10 min and monitored extravascular lung water (EVLW) accumulation thereafter with a double-indicator thermodilution technique. Final EVLW correlated highly with gravimetric values (r = 0.93, P less than 0.01). HCl in concentrations of 0.1-6 N when added to heated carbon (120 degrees C) and cooled to 39 degrees C produced airway damage but no pulmonary edema. Acrolein, in contrast, produced airway damage but also pulmonary edema, whereas capillary wedge pressures remained stable. Low-dose acrolein smoke (less than 200 ppm) produced edema in two of five animals with a 2- to 4-h delay. Intermediate-dose acrolein smoke (200-300 ppm) always produced edema at an average of 147 +/- 57 min after smoke, whereas high-dose acrolein (greater than 300 ppm) produced edema at 65 +/- 16 min after smoke. Thus acrolein but not HCl, when presented as a synthetic smoke, produced a delayed-onset, noncardiogenic, and peribronchiolar edema in a roughly dose-dependent fashion.

    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 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.

    To evaluate the efficacy and safety of treatment of diabetic macular edema (persistent type) with difluprednate ophthalmic emulsion 0.05 % (off label use). 20 patients with persistent diabetic macular edema were enrolled. In all subjects, more than 4 months had passed since prior treatment. All patients were treated with difluprednate ophthalmic emulsion 0.05 % three times daily for 3 months. At the end of 3 months the visual acuity had increased by two lines to a mean value of 0.61 ± 0.18 on logMAR from a baseline value of 0.885 ± 0.20 and the central retinal thickness had decreased from 423 ± 72.04 microns to 345 ± 68.7 microns. Hence, there was a total of 18.4 % decrease in retinal thickness on difluprednate. Major side effects included raised intraocular pressure in 20 %. Difluprednate is a potent and strong steroid which causes a rapid decrease in persistent diabetic macular edema. However, the potential side effect of raised intraocular pressure limits its use as an adjuvant therapy in non-steroid responders. PMID:26296375

    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.

    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

    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.

    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.

    Full Text Available Massive vulval edema with severe preeclampsia is presented as one of the consequences that may appear on patients with hypertension disorders during pregnancy, therefore the attention in the Obstetrics and Gynecology Service must be systematical and permanent. On women with hypertensive disorders during pregnancy, although edemas may not be constant, they may either appear at minor, barely perceptible extents, or even in the most severe ways, such as anasarca. A very peculiar manifestation of edema on preeclampsia is massive vulval edema, which appears as a highly rare complication, in whose basis there is a complex, systemic pathological process involved. We present a case of a pregnant woman who was admitted with high blood pressure values and excessive weight gain, plus very noticeable general edemas, and during her stay developed massive vulval edema. No data on this complication were found in the bibliography reviewed. Very few experienced professionals recall having dealt with similar cases in the last fifteen years, hence the decision to publish it.

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.

    International Nuclear Information System (INIS)

    Objective: To determine the prevalence and pattern of congenital malformations among neonates in a teaching hospital. Methods: The prospective hospital-based study was conducted over a period of 18 months in the neonatal unit of Combined Military Hospital, Kharian, from September 2011 to February 2013. All neonates from newborn to 28 days of age admitted to the unit irrespective of their condition comprised the study population. Neonatal examination was done by the Registrar at the time of admission followed by neonatologist/paediatrician. Information regarding gender, weight, gestational age, mode of delivery, consanguinity, maternal age, antenatal visit record and family history were recorded on a predesigned proforma. After clinical examination, if required, relevant investigations like ultrasonography, radiology, echocardiography, laboratory and genetic studies were done to confirm diagnosis. Data was statistically analysed by using SPSS 20. Results: Out of 3,210 total admissions, 226 (7%) neonates were congenitally malformed. Of them, 130 (57.52 %) were male and 96 (42.47 %) females. Among different body systems affected, anomalies related to the central nervous system were 46(20.35%) musculoskeletal 42(18.58%), genitourinary 34 (15.04%), cardiovascular system 30 (13.27%), ear, eye, face, neck 27(11.94%), digestive system 19 (8.40%), syndromes and skin 14 (6.19%) each. Conclusion: Congenital Malformations are not rare in our community and central nervous system is the most commonly affected system. Healthcare managers must stress upon primary prevention in the form of vaccination, nutrition and drugs to decrease preventable share of congenital malformations. (author)

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

    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.

    2000-01-01

    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.

    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 PURPOSE: To evaluate the effect of a single intravitreal bevacizumab injection on visual acuity, contrast sensitivity and optical coherence tomography-measured central macular thickness in eyes with macular edema from branch retinal vein occlusion. METHODS: Seventeen eyes of 17 patients with macular edema from unilateral branch retinal vein occlusion were treated with a single bevacizumab injection. Patients were submitted to a complete evaluation including best corrected visual acuity, contrast sensitivity and optical coherence tomography measurements before treatment and one and three months after injection. Visual acuity, contrast sensitivity and optical coherence tomography measurements were compared to baseline values. RESULTS: Mean visual acuity measurement improved from 0.77 logMAR at baseline to 0.613 logMAR one month after injection (P=0.0001 but worsened to 0.75 logMAR after three months. Contrast sensitivity test demonstrated significant improvement at spatial frequencies of 3, 6, 12 and 18 cycles/degree one month after injection and at the spatial frequency of 12 cycles/degree three months after treatment. Mean ± standard deviation baseline central macular thickness (552 ± 150 µm reduced significantly one month (322 ± 127 µm, P=0.0001 and three months (439 ± 179 µm, P=0.01 after treatment. CONCLUSIONS: Bevacizumab injection improves visual acuity and contrast sensitivity and reduces central macular thickness one month after treatment. Visual acuity returns to baseline levels at the 3-month follow-up, but some beneficial effect of the treatment is still present at that time, as evidenced by optical coherence tomography-measured central macular thickness and contrast sensitivity measurements.

    Full Text Available Steven M Couch, Sophie J BakriMayo Clinic Department of Ophthalmology, Mayo Clinic, Rochester, MN, USAAbstract: Triamcinolone acetonide (TA is a corticosteroid that has many uses in the treatment of ocular diseases because of its potent anti-inflammatory and anti-permeability actions. Intraocular inflammation broadly referred to as uveitis can result from several causes, including the immune system and after ophthalmic surgery. One of the most common reasons for vision loss with uveitis is macular edema. TA has been used for many years as an intravitreal injection for the treatment of ocular diseases. Several case control studies have been reported showing the efficacy of TA in the treatment of intraocular inflammation and associated macular edema caused by Behcet’s disease, Vogt-Koyanagi-Harada syndrome, sympathetic ophthalmia and white dot syndromes. It has also been shown efficacious in cases of pars planitis and idiopathic posterior uveitis. Some authors have reported its use in postoperative cystoid macular edema. Many of the studies on the use of TA in controlling intraocular inflammation and concomitant macular edema showed its effect to be transient in many patients requiring reinjection. Complications can arise from intravitreal injection of TA including elevated intraocular pressure and cataract. Rarely, it can be associated with infectious and non-infectious endophthalmitis. TA may be useful as an adjuvant in the treatment of uveitis and its associated macular edema, especially in patients resistant or intolerant to standard treatment.Keywords: triamcinolone acetonide, Behcet’s disease, sympathetic ophthalmia, Vogt-Koyanagi-Harada syndrome, white dot syndromes, uveitis, cataract surgery, macular edema, endophthalmitis

    Full Text Available BACKGROUND: Intrauterine exposure to antidepressants may lead to neonatal symptoms from the central nervous system, respiratory system and gastrointestinal system. Finnegan score (Neonatal Abstinence Score, NAS has routinely been used to assess infants exposed to antidepressants in utero. AIM: The purpose was to study neonatal maladaptation syndrome in infants exposed to selective serotonin reuptake inhibitors (SSRI or serotonin-norepinephrine reuptake inhibitors (SNRI in utero. METHOD: Retrospective cohort study of women using antidepressants during pregnancy and their infants. Patients were identified from the electronic health record system at Karolinska University Hospital Huddinge containing pre-, peri- and postnatal information. 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.

    We report the case of a 70-year-old female patient who developed corneal edema and iris discoloration following the inadvertent use of 1% methylene blue instead of 0.025% trypan blue to stain the anterior capsule during cataract phacoemulsification surgery. Copious irrigation was performed upon realization of incorrect dye use. Corneal edema and iris discoloration developed during the early postoperative period and persisted at 24-months follow-up. However, keratoplasty was not required. The intracameral use of 1% methylene blue has a cytotoxic effect on the corneal endothelium and iris epithelium. Copious irrigation for at least 30 min using an anterior chamber maintainer may improve outcomes. PMID:27224079

    Full Text Available Toshiyuki Oshitari1, Noriko Asaumi1, Masaru Watanabe1, Ken Kumagai1, Yoshinori Mitamura1,21Department of Ophthalmology, Kimitsu Central Hospital, Kisarazu City, Chiba, Japan; 2Department of Ophthalmology and Visual Science, Chuo-ku, Chiba, JapanAbstract: We report a case of severe diabetic macular edema (DME that developed after pioglitazone was used by a patient with proliferative diabetic retinopathy. A 30-year-old woman with poorly controlled type 2 diabetes mellitus visited our clinic in 2004. She had moderate pre-proliferative diabetic retinopathy OU. Because of the rapid progression of the diabetic retinopathy, she received pan-retinal photocoagulation in both eyes. Two weeks before using pioglitazone, her visual acuity was 0.9 OD and 0.7 OS. On October 2007, pioglitazone was prescribed by her internist because of poorly controlled blood glucose level. Two weeks later, her body weight increased, and her face became edematous. Her visual acuity decreased to 0.5 OU, and ophthlamoscopy showed severe DME in both eyes. Two weeks after stopping pioglitazone, her visual acuity improved to 0.8 OD and 0.5 OS, but the DME was still severe in the optical coherence tomographic images. Then, one half the usual dose (25 mg of spironolactone, a diuretic, was given and her macular edema was resolved. Her final visual acuity improved to 0.9 OD and 0.7 OS. We recommend that when a patient taking pioglitazone complains of decreased vision, the physician should promptly consult an ophthalmologist.Keywords: pioglitazone, diabetic macular edema, spironolactone, optical coherence tomography

    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.

  9. Uveitic Macular Edema: Quantitative assessment using optical coherence tomography and correlation with Visual Acuity

    International Nuclear Information System (INIS)

    Purpose was to evaluate the correlation between improvement in visual acuity (VA) and the reduction in central macular thickness (CMT) after treatment in uveitic macular edema. Twenty-nine eyes of 19 consecutive patients were studied prospectively. Inclusion criteria were studied prospectively. Inclusion criteria were: (1) verification of macular edema by optical coherence tomography (OCT), (2) adequate media clarity for fundus visualization, and (3) absence of coexisting ocular disease limiting visual potential. All patients have the following ophthalmic examination: best-corrected Snellen VA, slit-lamp examination, indirect ophthalmoscopy, fundus biomicroscopy, OCT and fluorescein angiography. There were 11 males and 8 females with a mean age of 40.58+-9.5 years (range 22 to 54 years). Eleven patients had presumed intraocular tuberculosis, four had Behaet's disease, three had pars planitis, and one had ankylosing spondylitis. At baseline, the mean logarithm of the minimum angle of resolution (logMAR) V.A. was 0.6841+-0.5186 (Snellen equivalent, 20/100), and mean CMT was 419.5+-105.9 mm. All patients received adequate immunosuppressive treatment and patients with presumed intraocular tuberculosis received in addition antituberculosis therapy. After a mean follow-up period of 4.3+-2.8 months, the mean logMAR VA was 0.231+-0.178 (Snellen equivalent, 20/30) and the mean CMT was 250.9+-41.9 mm. The improvement in VA and the reduction of CMT were significant (p<0.0001for both comparisons). OCT is useful in monitoring the efficacy of treatment in patients with uveitic macular edema. (author)

    Full Text Available Objectives: To compare the effect of a single intravitreal triamcinolone acetonide (IVTA injection in eyes with diabetic macular edema (DME of different patterns determined by optical coherence tomography (OCT. Materials and Methods: In the present study, we retrospectively reviewed the records of patients who had a single IVTA injection for the treatment of DME. Eyes with a clinically significant macular edema and a central foveal thickness (CFT of 250 microns or more were included. Diabetic retinopathy stage and previous history of laser treatment were not taken into account for patient selection. Bestcorrected visual acuity (BCVA, CFT, and total macular volume values before and after the injection were analyzed. The eyes were divided into 3 groups according to the morphology on OCT: DRT (sponge-like diffuse retinal thickening, CME (cystoid macular edema, and SRD (serous retinal detachment groups. Results: 104 eyes (50 with DRT, 30 with CME, and 24 with SRD were included in the study. Post-injection measurements were obtained 9.65±2.27 weeks after the injection. There was no statistically significant difference between the three groups regarding the change in BCVA (p=0.212. The variations in the amount and percentage of change in CFT among the groups was statistically significant (p=0.001 and p=0.001, respectively. Although the difference between CME and SRD groups was not statistically significant, both groups had significantly greater reductions in CFT compared to the DRT group. Conclusion: DME improved better in CME and SRD groups in response to a single dose of IVTA. However, the visual outcomes did not differ significantly between the groups.

    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

    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

    Full Text Available The authors report a case of a preterm neonate who presented with lid edema, corneal edema, and an inflammatory membrane with whitish exudates in the pupillary area, suggestive of endophthalmitis. There was also a cutaneous ulcer with an eschar on the right wrist at the site of extravasation associated with previous intravenous catheter. Cultures from the ulcer and vitreous samples both grew Serratia marcescens with identical antibiotic sensitivity and resistance patterns. The ocular infection was rapidly progressive and did not respond to administered medical and surgical therapy leading to subsequent phthisis bulbi. Serratia can cause endophthalmitis refractory to antibiotics and despite aggressive and timely treatment can have an unfavorable outcome. This report aims at highlighting the possibility of metastatic infection from an extravasation injury with a potentially fatal outcome.

    2015-01-01

    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.

    Background Glioma-induced edema is considered as one of the most pathological characteristics of glioma and a significant source of morbidity and mortality.New strategies are needed for the treatment of peritumoral edema in glioma.Endostatin has been proven to be beneficial as an anti-angiogenic agent in experimental gliomas,but the effects are unclear.This study aimed to investigate the effects of endostatin on C6 glioma-induced edema.Methods Tumorigenic mice were established by subcutaneous injection of three glioma cell lines,C6-null cells and stable transfected-C6 cells overexpressing mock vector (C6-mock cells) and endostatin (C6-endo cells).Endostatin expression in xenograft C6 glioma was determined by immunostaining and Western blotting.Glioma-induced edema and tumor vessel permeability were assayed.The effect of endostatin on vascular enodothelial growth factor (VEGF) expression in vivo was analyzed by quantitative polymerase chain reaction (Q-PCR) and enzyme-linked immunosorbent assay (ELISA).The number of vesiculo-vascuolar organelles (VVOs) formed in tumor endothelia was calculated using electron microscopy.Data were analyzed by using one-way analysis of variance (ANOVA) followed by Dunnett's post hoc test for multiple comparisons to the control groups.Results Overexpression of endostatin (C6-endo cells) significantly suppressed tumor growth and reduced tumor edema and vessel permeability.ELISA analysis showed that the level of VEGF protein was markedly decreased in tumor from C6-endo cells compared with tumor from C6-null cells and C6-mock cells.Similar results were obtained by Q-PCR.Furthermore,the number of VVOs observed in tumor from C6-endo mice was significantly reduced compared with tumor from C6-null cells or C6-mock cells.Conclusions Our data provide primary evidence that endostatin reduces glioma-induced edema and vascular permeability.Using endostatin may be an effective strategy for treating glioma 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.

    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

    Full Text Available ABESTRACT: Introduction & objective: Inflammation is a body defensive response to the endogenous and exogenous stimulators such as chemical, radiation, trauma and invasive microorganism, which result pain and tissue necrosis. 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.

    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.

  19. Transient mega-esophagus in a neonate with congenital diaphragmatic hernia

    International Nuclear Information System (INIS)

    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.

  20. 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.

The patients were divided into two groups. In group 1, pars plana vitrectomy with removal of the posterior hyaloid was performed, and at the end of the procedure, IVTA 0.1 mL (40 mg/mL and bevacizumab 1.25 mg were injected. In group 2, macular grid laser photocoagulation was performed 2 weeks after the same intravitreal injection combination as used in group 1. The main outcome measures were best-corrected visual acuity (BCVA and central foveal thickness, which were measured using optical coherence tomography at 3, 6, and 12 months.Results: Changes in BCVA and central foveal thickness at 3, 6, and 12 months from baseline were highly statistically significant (P < 0.01. Mean BCVA was better in group 1 at 3 months, nearly equal at 6 months, and less at 12 months. Mean central foveal thickness was more improved in group 1 than in group 2 at 3 months, and was better in group 2 at subsequent measurement points. The major adverse events were development of cataract (more common in group 1 and elevation of intraocular pressure (more common in group 2.Conclusion: The combined therapy described here could represent a solution for the treatment of intractable diabetic macular edema, and could have a favorable long-term outcome. Combined treatment of IVTA and bevacizumab plus grid laser resulted in a more favorable

    2014-01-01

    Idiopathic pulmonary hemosiderosis (IPH) is a rare complex entity characterized clinically by acute or recurrent episodes of hemoptysis secondary to diffuse alveolar hemorrhage. The radiographic features are variable, including diffuse alveolar-type infiltrates, and interstitial reticular and micronodular patterns. We describe a 3-week-old infant presenting with hemoptysis and moderate respiratory distress. Idiopathic pulmonary hemosiderosis was the first working diagnosis at the Emergency Department and was confirmed, 2 weeks later, by histological studies (bronchoalveolar lavage). The immunosuppressive therapy by 1 mg/kg/d prednisone was immediately started, the baby returned home on steroid therapy at a dose of 0,5 mg/kg/d. The diagnosis of idiopathic pulmonary hemosiderosis should be evocated at any age, even in the neonate, when the clinical presentation (hemoptysis and abnormal radiological chest images) is strongly suggestive.

  8. 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)

  9. 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

    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.

    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.

    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.

    We evaluated the features of diabetic retinal and choroidal edema in Spontaneously Diabetic Torii (SDT) rats. We measured the retinal and choroidal thicknesses in normal Sprague-Dawley (SD) rats (n = 9) and SDT rats (n = 8). The eyes were enucleated 40 weeks later after they were diagnosed with diabetes, and 4-micron sections were cut for conventional histopathologic studies. The mean retinal and choroidal thicknesses were significantly thicker in the SDT rats than in the normal SD rats. The choroidal thickness was correlated strongly with the retinal thickness in both rat models. Diabetic retinopathy (DR) and diabetic choroidopathy appeared as edema in the SDT rats. The retinal thickness was correlated strongly with the choroidal thickness in the SDT rats, which is an ideal animal model of both DR and choroidopathy. PMID:26783535

    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.

  5. Updates in the Management of Diabetic Macular Edema

    OpenAIRE

    2015-01-01

    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...

    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 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.

  11. 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

    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.

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

  3. Management of upper airway edema caused by hereditary angioedema

    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.

    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.

    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.

    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.

  9. Synthesis of 11C-methylated inulin as a radiopharmaceutical for imaging brain edema and pulmonary edema

    International Nuclear Information System (INIS)

    11C-methylated inulin, supposedly useful for imaging of brain edema and pulmonary edema, was prepared using cyclotron produced 11CO2. The synthesis consists of the production of 11C-methyl iodide and its coupling with inulin alkoxide sodium in dimethylsulfoxide as solvent. 11C labeled inulin was purified by alcohol precipitation. The radiochemical yield of pure 11C-inulin was 34% of 11CO2 30 min after the end of bombardment. The blood clearance and body distribution of 11C was observed in rabbits after i.v. injection of 11C-inulin. The blood clearance curve was composed of a sum of three exponential functions. The gamma camera image showed that the 11C activity in blood moved quickly to kidneys and urine and a small dose of radioactivity remained persistently in edematous tissues, i.e. the edematous lung tissues produced by oleic acid treatment.

    2001-06-01

    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

    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

    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

    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.

    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

  15. 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.)

    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

    Our previous studies have shown that female mice have less brain edema and better recovery in neurological deficits after intracerebral hemorrhage (ICH) and that 17β-estradiol treatment in male mice markedly reduces ICH-induced brain edema. In this study, we investigated the role of gender and the estrogen receptors (ERs) in iron-induced brain edema. There were three parts in this study: (1) either male or female mice received an injection of 10 μL FeCl2 (1 mM) into the right caudate; (2) females received an intracaudate injection of FeCl2 or saline with 1 μg of ICI 182,780 (antagonists of ERs) or vehicle; and (3) males were treated with the ER regulator tamoxifen (5 mg/kg subcutaneously) or vehicle 1 h after FeCl2 injection. Mice were euthanized 24 h later for brain edema determination. FeCl2 induced lower brain edema in females than in males. Co-injection of ICI 182,780 with FeCl2 aggravated iron-induced brain edema in female mice. ICI 182,780 itself did not induce brain edema at the dose of 1 μg. Tamoxifen treatment reduced FeCl2-induced brain edema in male mice. In conclusion, iron induced less brain edema in female mice than in males. ER modification can affect iron-induced brain edema.

    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.

    Full Text Available Background: The term Spontaneous Intestinal Perforation (SIP suggests a perforation in the gastrointestinal tract of a newborn with no demonstrable cause.Methods: Four neonates presenting with spontaneous bowel perforation were analyzed with respect to clinical presentation, management and outcome.Results: The mean age at presentation was 11.4 days. There were three males and one female. One of the neonates was preterm, very low birth weight and the other three were full term. Two neonates underwent emergency exploratory laparotomy and two were initially managed by peritoneal drainage in view of poor general condition; one of them improved and did not require further operative intervention. The preterm very low birth weight neonate was stabilized and explored after 48 hours. Intra-operatively, two of them had two ileal perforations each which required ileostomy; one had single perforation in the transverse colon which was primarily repaired. All four had an uneventful recovery.Conclusion: SIP is a distinct clinical entity and has better outcome than neonates with intestinal perforation secondary to Necrotizing Enterocolitis (NEC.

    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.

    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

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

El edema pulmonar de altura (EPA es una entidad que pone en peligro la vida y que ocurre en sujetos predispuestos pero sanos. 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 Background: The paper tries to examine the effect of avastin on visual acuity in patients with Ischemic and non-ischemic diabetic macular edema which was estimated convenient, inexpensive, safe, and quick in contrast to laser or deep vitrectomy. Materials and Methods: In this clinical trial study, patients with clinically significant macular edema (CSMA were subjected to fluorescein angiography (FA and people whose foveal avascular zones (FAZ were over 1000 µm were defined as ischemic diabetic macular edema. Patients were divided into two ischemic and non-ischemic groups. The best corrected visual acuity (BCVA and the central macular thickness (CMT in all eyes were measured and recorded by optical coherence tomography (OCT. All patients received 3 vitreous injections of bevacizumab (avastin at 1-month intervals. One month after the third injection, BCVA and CMT were measured again and patient’s information was compared before and after the injection. Results: Out of 87 eyes (66 patients, 23 eyes (26.4% belonged to ischemic group and 64 eyes (73.6% belonged to non-ischemic group. In ischemic group, BCVA improved from 0.653 ±0.309 LogMAR to 0.404 ±0.255 LogMAR (p=0.001, while no significant change was seen in non-ischemic group (from 0.881 ±0.332 to 0.879 ±0.378. In ischemic group, CMT was increased from 362.9±34.66 to 278.76 ± 45.57 and in non-ischemic group it was enhanced from 353.47 ±67.61 to 239.87±55.44 (p=0.001.Conclusion: In spite of the great impact of vitreous injection of avastin in reducing the central macular thickness in both ischemic and non-ischemic groups and sensible improvement of patients’ visibility, the visibility itself was not improved considerably in ischemic group.

    Purpose. To compare treatment areas and navigated macular laser photocoagulation (MLP) plans suggested by retro-mode scanning laser ophthalmoscopy (RM-SLO) image versus optical coherence tomography (OCT) central retinal thickness map and treatment planning among retina specialists. Methods. Thirty-nine eyes with diabetic or branch retinal vein occlusion-related ME undergoing navigated MLP with navigated photocoagulator had OCT and RM-SLO taken. OCT map and RM-SLO image were imported to the photocoagulator and aligned onto the retina. Two retina specialists placed laser spot marks separately based on OCT and RM-SLO images in a random fashion. The spots placed by each physician were compared between OCT and RM-SLO and among physicians. The areas of retinal edema on OCT and RM-SLO of the same eye were also compared. Results. The average number of laser spots using RM-SLO and OCT template was 189.6 ± 77.4 and 136.6 ± 46.8, respectively, P = 0.003. The average area of edema on RM-SLO image was larger than that on OCT map (14.5 ± 3.9 mm(2) versus 10.3 ± 2.8 mm(2), P = 0.005) because of a larger scanning area. There was narrow variability in treatment planning among retina specialists for both RM-SLO (P = 0.13) and OCT (P = 0.19). Conclusion. The RM-SLO image superimposed onto the fundus of the same eye can be used to guide MLP with narrow variability in treatment planning among retina specialists. The treatment areas suggested by RM-SLO-guided MLP plans for ME were shown to be larger than those suggested by OCT-guided plans. PMID:26989498

    Full Text Available Diabetic retinopathy is the leading cause of blindness among individuals of working age in advanced societies, most of the vision loss resulting from diabetic macular edema (DME. Macular laser photocoagulation or intravitreal tiamcinolone or anti-vascular endothelial growth factor injection are modalities of therapy for diabetic macular edema. This study aim was to present the clinical outcomes of 60 eyes of 41 patients with diffuse DME who treated with macular laser grid (MLG alone or combined with intravitreal triamcinolone (IVTA and intravitreal bevacizumab (IVB injection. Thirty eyes (group1 treated with MLG and 30 eyes (group 2 treated with MLG + IVB + IVTA. The values of BCVA, central macular thickness (CMT, intraocular pressure (IOP and complications were compared between two groups. At baseline, BCVA was 0.35 ± 0,18 LogMAR (logarithm of the minimum angle of resolution in the group 1 and 0.36 ± 0.36 ± 0.14 logMAR in the group 2. At 6 and 20 months after initial treatment in both groups had no significant improvement in BCVA, whereas had a significant improvement in CMT (p < 0.001 compared with baseline. An increase in IOP was present in 13 % and cataract was developed in 6.7 % in the group 2. At 6th and 20th month, MLG and MLG + IVTA + IVB provided improvement of BCVA and CMT in the both groups. There was no significant difference in BCVA and CMT between two groups. Increased IOP and development of cataract was recorded in the group 2 secondary to IVTA. MLG may be preffered for treatment of DME because of side events of IVTA + IVB.

    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

  11. Fetal and neonatal thyrotoxicosis

    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.

    Full Text Available Este artigo refere-se à pesquisa acerca do padrão espacial dos componentes neonatal e pós-neonatal da mortalidade infantil em Goiânia, no Estado de Goiás, Brasil. 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 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.

    Full Text Available Negative pressure pulmonary edema (NPPE is a rare complication that can occur after acute upper airway obstruction or secondary to relax chronic upper airway obstruction and a life-threatening fatal condition. The first cause in the etiology of NPPE is developed laryngospasm after intubation or extubation, while the other causes are epiglottitis, croup, hiccups, foreign body aspiration, pharyngeal hematoma and oropharyngeal tumors. Supportive therapy is usually the only treatment. The fundamental principle of treatment is early diagnosis and to provide adequate oxygenation. Application of positive airway pressure is often provided with CPAP in most of patients, but sometimes re-intubation and mechanical ventilation may be required.

    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.

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.

    2006-12-01

    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

  1. CT of the neonatal head

    International Nuclear Information System (INIS)

    Computed tomography (CT) is used less often than other techniques on neonatal units. However, in the acute setting, CT can be invaluable in diagnosing or excluding potentially life-threatening conditions and guiding initial management in neonates. Common indications for scanning include trauma, suspected non-accidental injury, infection, or an acute hypoxic or metabolic event. The aim of this review is to provide an overview of the normal neonatal head at CT and compare this to the common pathological abnormalities. Several key features of each condition will be highlighted. It is important to note that some pathological conditions can have overlapping features at CT and, therefore, the clinical history and additional investigations are also of key importance in determining the diagnosis

    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.

    2014-01-01

    Neonates are the most vulnerable age group in terms of anesthetic risk and perioperative mortality, especially in the developing world. Prematurity, malnutrition, delays in presentation, and sepsis contribute to this risk. Lack of healthcare workers, poorly maintained equipment, limited drug supplies, absence of postoperative intensive care, unreliable water supplies, or electricity are further contributory factors. Trained anesthesiologists with the skills required for pediatric and neonatal anesthesia as well as basic monitoring equipment such as pulse oximetry will go a long way to improve the unacceptably high anesthetic mortality.

    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.

    Pulmonary edema is a frequent condition found in adult patients hospitalized in cardiology wards and intensive care units. Ultrasonography is a diagnostic modality with a high sensitivity for the detection of extravascular lung water, visualized as B lines, and usually caused by cardiogenic or noncardiogenic pulmonary edema. This paper highlights a simple method for the assessment of patients with pulmonary edema, which allows for a differential diagnosis of its possible mechanism and contributes to therapeutic intervention guiding and monitoring.

    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.

Methods: A local ethics committee-approved technique of an intravitreal injection of pure perfluoropropane gas (C3F8 was performed for all participants. After a period of prone positioning, the patients underwent regular and detailed clinical review. Main outcome measures: The induction of a PVD, change in macular thickness, change in visual acuity. Results: A PVD was induced in all five eyes with subsequent signs of reduction in macular thickness and resolution of exudates. Mean visual improvement was 11 ETDRS (Early Treatment Diabetic Retinopathy Study letters (range 4–21. Apart from a transient vitreous hemorrhage in one eye, there were no significant treatment-related complications. Conclusion: The induction of a PVD by pneumatic retinopexy appears to have a significant influence on diabetic macular edema in eyes which have not successfully responded to macular laser therapy. A randomized clinical trial is justified on the basis of the initial promising data. Keywords: optical coherence tomography, OCT, posterior vitreous detachment, perfluoropropane

    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 neuroprotective clinical

    We attempted to evaluate the diagnostic usefulness of the degree of perilesional edema around intracerebral hematoma in predicting the underlying cause. This study included 54 patients with intracerebral hematoma for whom the underlying cause was confirmed by biopsy, radiological or clinical methods. Cases of subarachnoid hemorrhage, hemorrhagic transformation of cerebral infarction and intraventricular hemorrhage were excluded. The lesion size was defined as the average value of the longest axis and the axis perpendicular to this. The size of the perilesional edema was defined as the longest width of the edema. In all cases, the sizes of the lesion and edema were measured on the T2 weighted image. We defined the edema ratio as the edema size divided by the lesion size. 23 cases were diagnosed as intracerebral hemorrhage due to neoplastic conditions, such as metastasis (n=17), glioblastoma (n=5), hemangioblastoma (n=1). 31 cases were caused by non-neoplastic conditions, such as spontaneous hypertensive hemorrhage (n=23), arteriovenous malformation (n=4), cavernous angioma (n=3), and moya-moya disease (n=1). In fourteen cases, which were confirmed as malignant intracerebral hemorrhage, the edema ratio was more than 100%. Of the other cases, only 8 were confirmed as malignant intracerebral hemorrhage. It was found that the larger the edema ratio, the more malignant the intracerebral hemorrhage, and this result was statistically significant (p<0.001). Measurement of perilesional edema and the intracerebral hematoma ratio may be useful in predicting the underlying causes.

    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.

    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.

    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.)

    Full Text Available ABSTRACT: INTRODUCTION: Jaundice is most common problem faced by neonates in the first week of life. Although physiological jaundice is mor e frequent as compared to pathological jaundice it is very important to differentiate betwe en the two as pathological jaundice may lead to kernicterus and subsequently brain damage. There are various modalities of investigations e.g. Serum bilirubin, Direct and indirect coomb’s t est, Blood group, G-6PD deficiency, reticulocyte count by which we can reach at diagnos is. Treatment is also dependent upon the amount of serum bilirubin and various other laborat ory investigations. Thus laboratory workup is very important for diagnosis and prevention of ne onatal hyperbilirubinemia in newborn. With this background present study was conducted to study the clinico- pathological profile among infants with neonatal hyperbilirubinemia. METHODOLOGY: A prospective study was carried out for the duration of 1 year in one of th e teaching hospitals. RESULTS: Altogether 63 babies were enrolled in the study. Male babies out numbered the female (58.7% vs. 41.3%.Mean age of the study population was 2.97 da ys with standard deviation of 1.2 days. Percentage of Pre-term babies was 30.1. Neonates ha ving low birth weight were 17(26.9%. Physiological jaundice constituted (4062% cases of Neonatal hyperbilirubinemia. ABO incompatibility was the commonest cause of pathologic al jaundice followed by septicemia. Statistically significant rise in the serum bilirub in was noted in pathological jaundice as compared to physiological jaundice. C-reactive protei n (CRP was found to be positive in all the cases of septicemia. Direct and indirect Coomb’s te st was positive in all the cases with Rh incompatibility. CONCLUSION: Neonatal hyperbilirubinemia is associated with various other clinical morbidities. Causes of hyperbilirubinemia s hould be investigated comprehensively. ABO and Rh typing should be done along with Coombs Test

    Full Text Available Massive vulval edema with severe preeclampsia is presented as one of the consequences that may appear on patients with hypertension disorders during pregnancy, therefore the attention in the Obstetrics and Gynecology Service must be systematical and permanent. On women with hypertensive disorders during pregnancy, although edemas may not be constant, they may either appear at minor, barely perceptible extents, or even in the most severe ways, such as anasarca. A very peculiar manifestation of edema on preeclampsia is massive vulval edema, which appears as a highly rare complication, in whose basis there is a complex, systemic pathological process involved. We present a case of a pregnant woman who was admitted with high blood pressure values and excessive weight gain, plus very noticeable general edemas, and during her stay developed massive vulval edema. No data on this complication were found in the bibliography reviewed. Very few experienced professionals recall having dealt with similar cases in the last fifteen years, hence the decision to publish it.El edema vulvar masivo con preeclampsia grave se presenta como una de las consecuencias que pueden aparecer en pacientes con trastornos de hipertensión en el embarazo, por lo que la atención en el Servicio de Obstetricia debe ser sistemática y permanente.

    Full Text Available Purpose : Sepsis is a significant cause of morbidity and mortality in the newborn, particularly in preterm. The objective of this study was to analyze the incidence rate, causative pathogens and clinical features of neonatal sepsis in one neonatal intensive care unit (NICU for 6 years. Methods : This study was retrospectively performed to review the clinical and laboratory characteristics including sex, gestational age, birth weight, Apgar score, length of hospitalization, length of total parenteral nutrition, presence of central venous catheter, underlying diseases, laboratory findings, microorganisms isolated from blood culture, complications and mortality in 175 patients between January 2003 and December 2008. Results : 1 Sepsis was present in 175 of 3,747 infants for 6 years. There were more gram-positive organisms. 2 The gram-negatives were more prevalent in preterm. There were no significant differences of other clinical features between two groups. 3 Underlying diseases were found in 73.7%, and the most common disease was cardiovascular disease. The most common organisms of gram-positives and gram-negatives were methicillin resistant Staphylococcus aureus (MRSA and Serratia marcescens. 4 There was statistically significant difference on platelet counts between two groups (P&lt;0.05. 5 Complications were found in 18.3% and septic shock was the most common. MRSA was the most common pathogen in sepsis with complication. 6 The mortality rate was 7.4%. 7 There were differences in monthly blood stream infection/ 1,000 patient-days. Conclusion : The studies about the factors that can influence neonatal sepsis will contribute to decrease the infection rates in NICUs.

Despite recent advances in the management of neonatal sepsis, including use of more potent antibiotics, timely identification continues to be a frequent and challenging problem in the management of the newborn or high-risk neonate in the neonatal intensive care unit. Lack of specific early objective diagnostic evaluations or specific signs and symptoms, especially in the preterm infant, impedes early identification. However, emerging technologies linked with enhanced understanding of the immature and developing neonatal immune system responses to early infection provide an opportunity to develop critically needed biomarkers to improve early identification in this high-risk population. This review will focus on the field of neonatal sepsis biomarker development, identifying current promising biomarkers that have been investigated and widely utilized, as well as provide insight into recent advances and the rapidly evolving technologies that are being exploited in biomarker development to improve diagnosis, treatment, and prognosis in neonatal sepsis.

    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

    2009-01-01

    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.

  19. Photodegradation of riboflavin in neonates

    International Nuclear Information System (INIS)

    The biologically most important flavins are riboflavin and its related nucleotides, all highly sensitive to light. It is because of its photoreactivity and its presence in almost all body fluids and tissues that riboflavin assumes importance in phototherapy of neonatal jaundice. The absorption maxima of both bilirubin and riboflavin in the body are nearly identical: 445-450 (447) nm. In consequence, blue visible light will cause photoisomerization of bilirubin accompanied by photodegradation of riboflavin. This results in diminished erythrocyte glutathione reductase, which indicates generalized tissue riboflavin deficiency and red cell lysis. Single- and double-strand breaks in intracellular DNA have occurred with phototherapy. This light exposure of neonates may result also in alterations of bilirubin-albumin binding in the presence of both riboflavin and theophylline (the latter frequently given to prevent neonatal apnea). Many newborns, especially if premature, have low stores of riboflavin at birth. The absorptive capacity of premature infants for enteral riboflavin is likewise reduced. Consequently, inherently low stores and low intake of riboflavin plus phototherapy for neonatal jaundice will cause a deficiency of riboflavin at a critical period for the newborn. Supplementation to those infants most likely to develop riboflavin deficiency is useful, but dosage, time, and mode of administration to infants undergoing phototherapy must be carefully adjusted to avoid unwanted side effects

    Full Text Available Neonatal septicemia is a major cause of mortality and morbidity in horses in their first seven days of life and within their pathophysiology. It is important to consider the extrinsic and intrinsic predisposing factors which make foals susceptible to agents of primarily bacterial etiology. However, other types of infectious etiology (viruses and fungi should be considered too, as well as noninfectious etiologies. The paper mentions a wide variety of mechanisms that produce different injuries that must be addressed with measures of critical neonatal care, so it is imperative for the veterinarian to know the pathogenic mechanisms of the disease, its clinical presentation and anatomo-pathological lesions. Thus, systemic inflammatory response syndrome (SIRS, multiple organ dysfunction syndrome (MODS, and peripheral circulatory collapse or shock are some of the elements defined as the pillars of the pathophysiology of neonatal septicemia, extensively studied in equine medicine. This paper presents a short review of the triggering mechanisms of neonatal septicemia highlighting the importance of epidemiological investigations in Colombia. It shows the need for retrospective and prospective studies and for divulgation of some of the preventive measures of the disease in horses.

    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.

    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.

Following the initial injection, a retreatment was performed for any persistent macular edema, unless there had been no previous response to repeated doses. Recorded parameters included visual acuity, CRT on optical coherence tomography (spectral domain optical coherence tomography [SD-OCT], and SD-OCT characteristics. Comparisons were made between data at baseline and 12 months after the first injection, and differences were tested for statistical significance using the Student's t-test.Results: In all, 175 eyes of 142 patients were analyzed. Patients in group 2 (CRT >400 µm had significantly more injections than group 1 (CRT <400 µm (4.0 versus 3.3; P=0.003. Both groups had similar numbers of eyes with preexisting epiretinal membrane and/or vitreomacular traction at baseline. The reduction in CRT was significantly greater in group 2 when compared to group 1 (P<0.0001. In terms of visual gain between baseline and month 12, each gained significantly by a mean of 0.12 logarithm of the minimum angle of resolution units (P=0.0001, but there was no difference between groups 1 and 2 (P=0.99.Conclusion: These results do not support a 400 µm baseline CRT cut-off for treating DME

    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.

    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.

    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.

  12. 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.

    Full Text Available Michael W StewartDepartment of Ophthalmology, Mayo School of Medicine, Jacksonville, FL, USAAbstract: The treatment of center-involving diabetic macular edema (DME has improved because of the proven efficacy of drugs that inhibit the effects of vascular endothelial growth factor (VEGF. The newest anti-VEGF drug, aflibercept, has recently been approved by the United States Food and Drug Administration for the treatment of center-involving DME and for diabetic retinopathy in eyes with DME. In the pivotal Phase III VISTA and VIVID trials, intravitreal aflibercept 2 mg injections every 4 or 8 weeks (after 5 monthly loading doses produced superior gains in BCVA compared to laser/sham injections. In the Diabetic Retinopathy Clinical Research Network Protocol T trial, which featured monthly anti-VEGF monotherapy for 6 months, followed by monthly pro re nata anti-VEGF injections with laser rescue therapy from months 6 through 12, aflibercept 2 mg monthly was superior to bevacizumab 1.25 mg and ranibizumab 0.5 mg in eyes with BCVA of 20/50 or worse (aflibercept versus bevacizumab: P<0.001; aflibercept versus ranibizumab: P=0.003, but the three regimens were comparable for eyes with VA of 20/40 or better. Only in the 20/50 or worse subgroup did aflibercept achieve clinical superiority (>5 letter difference to bevacizumab. Each treatment regimen led to significant macular thinning, with aflibercept being superior to bevacizumab in both visual acuity subgroups (P<0.001 for each, but it was not statistically superior to ranibizumab in either group. In diabetic patients, aflibercept has an excellent safety profile that does not appear to differ from laser/sham or other VEGF inhibitory drugs.Keywords: aflibercept, bevacizumab, diabetic macular edema, ranibizumab, vascular endothelial growth factor

    Neonatal hyperglycemia is a metabolic disorder found in the neonatal intensive care units. Neonatal diabetes mellitus (NDM) is a very uncommon cause of hyperglycemia in the newborn, occurring in 1 in every 400,000 births. There are two subtypes of neonatal diabetes mellitus: permanent neonatal diabetes mellitus (PNDM) and transient neonatal diabetes mellitus (TNDM). We describe a term, small for gestational age, female neonate with transient neonatal diabetes mellitus who presented with poor feeding tolerance and vomiting associated with hyperglycemia (385 mg/dL), glycosuria, and metabolic acidosis within the first 12 hours of life. The neonate was treated with intravenous insulin, obtaining a slight control of hyperglycemia. An adequate glycemia was achieved at 5 weeks of life. The molecular studies showed complete loss of maternal methylation at the TND differentially methylated region on chromosome 6q24. The etiology of this neonate's hyperglycemia was a hypomethylation of the maternal TND locus. A rare cause of neonatal diabetes mellitus must be considered if a neonate presents refractory hyperglycemia. To our knowledge, this is the first case reported in Puerto Rico of transient neonatal mellitus due to the uncommon mechanism of maternal hypomethylation of the TND locus. Its prevalence in Puerto Rico is unknown. PMID:26576310

    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

  16. 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

    Objective: Assessment of serum Zinc in LBW (Low Birth Weight) and appropriate for gestational age (AGA) neonates in relation to their maternal zinc level. Materials and Methods: A prospective study was conducted in a tertiary care teaching hospital of central India between August 2011 to July 2012. Serum samples were collected from the eligible LBW (preterm & term IUGR) and term AGA healthy neonates and their mothers for zinc level estimation. Serum zinc was measured by atomic absorption spectrophotometer. Newborn of mothers having any medical illness, on any medication, with anaemia (Hb 2.5kg) were categorized as control group. Mean serum zinc level was significantly low in LBW neonates (83.45±16.74 μg/dl) in comparison to term AGA newborns (93.74±19.95 μg/dl), (p-value <0.05). Similarly, zinc level was also low in mothers of LBW babies (67.02±15.99 μg/dl) in comparison to mothers of term AGA newborns (83.59±18.46 μg/dl), (p-value < 0.05). Low maternal zinc levels were significant correlated with lower serum zinc in LBW neonates (Pearson correlation value - 0.938). However, maternal zinc levels have shown no significant correlation with neonatal serum zinc levels in term AGA (0.029). Conclusion: LBW neonates and their mothers have significant zinc deficiency as compared to term AGA neonates and their mothers and this deficiency is correlated with zinc deficiency in mothers of these LBW neonates.

    Full Text Available This paper seeks to establish the effect of region of residence on neonatal and post-neonatal mortality inKenya, using the 2003 Kenya Demographic and Health Survey data. The results show significant regionalvariation in neonatal and post-neonatal mortality. Both neonatal and post-neonatal mortality were alsofound to vary significantly according to household wealth status, household water supply, and toilet facility,maternal age at birth, preceding birth interval; antenatal visits and type of place of delivery. It was only postneonatalmortality that also varied significantly according to maternal education.The study recommends that concerted efforts be made to reduce high neonatal and post-neonatal mortalityin the high mortality areas. These could entail strengthening existing family planning, child survival and HIV/AIDS programmes alongside improving households’ access to piped water supply and household hygiene practices.

    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.

To study the CT brain patterns in infants with hypothermia and neurological symptoms. Materials and methods. We reviewed the brain CT of nine infants with neonatal hypothermia, multiple organ failure, seizures and coma. Results. Two infants had normal CT scans, acutely and at follow-up, and were clinically normal at follow-up. In seven infants, CT showed diffuse cerebral oedema, with reversal of the normal density relationship between grey and white matter and a relative increased density of the thalami, brainstem and cerebellum - the `reversal sign`. In six surviving infants with severe developmental delay, follow-up CT revealed cerebral atrophy with multicystic encephalomalacia. Conclusions. The `reversal sign` has been described in the abused child, birth asphyxia and anoxia due to drowning. Neonatal hypothermia is offered as a further cause. (orig.) With 6 figs., 1 tab., 13 refs.

    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.

Syntomatic treatment was given at the outset of the diseases. But did not have any positive results

    Full Text Available Neonatal septicemia remains a significant cause of morbidity and mortality in the new born, more so in developing countries like India due to delivery and post natal follow up in an unclean environment having more chances of contamination with infective organisms. Infection is more common in the neonatal period than at any other time in life . 1 This is partly attributable to exposure to large number of organisms, but is also due to a relative failure of the neonatal host defenses to clear microorganisms from blood and tissues. The rate of infection and type of organism causing sepsis in a neonate vary with demography. In India, the incidence of neonatal septicemia is 10 - 30/1000 live births , 2 whereas in western countries it is 1 - 8/1000 live births . 3 KEYWORDS: Neonatal, Sepsis, Staphylococcus, CRP, Bandemia

    Full Text Available The transport o f ill neonates between hospitals and/or health care centres, plays an important role in the mortality rate o f these seriously ill neonates. It is therefore important that the ill neonate is transported under optimal conditions. A lack o f standards in this regard hampers the evaluation o f the quality o f inter hospital transport o f ill neonates. The purpose o f this study is to formulate valid standards fo r the transport o f seriously ill neonates between hospitals (and/or other health care institutions to form the basis fo r the evaluation o f the quality o f this service. Factors that need to be considered in the transport o f ill neonates include the ambulance, equipment and stock, the transport personnel and communication. These factors were systematically explored and described and standards were formulated accordingly.

    Full Text Available Anaerobic bacteria are well known causes of sepsis in adults but there are few studies regarding their role in neonatal sepsis. In an attempt to define the incidence of neonatal anaerobic infections a prospective study was performed during one year period. A total number of 400 neonates under sepsis study were entered this investigation. Anaerobic as well as aerobic cultures were sent. The patients were subjected to comparison in two groups: anaerobic culture positive and anaerobic culture negative and this comparison were analyzed statistically. There were 7 neonates with positive anaerobic culture and 35 neonates with positive aerobic culture. A significant statistical relationship was found between anaerobic infections and abdominal distention and pneumonia. It is recommended for those neonates with abdominal distention and pneumonia refractory to antibiotic treatment to be started on antibiotics with anaerobic coverage.

    Pain expression in both pre-term and term infants is a little understood phenomenon. Recent research has generated data documenting that the newborn can feel pain, can act to avoid the pain, and may form memory traces of the experience. ”Nociceptive activity” or ”noxious stimuli” are better terms to use when addressing aversive stimulation of the neonate because they encourage scrutiny of the behavioural and physiologic responses of the newborn without placing emphasis on the emotional and su...

    A retrospective cohort study was carried out to test the hypothesis that children born at term with cerebral palsy with signs of neurological dysfunction preceded by depression at birth (termed neonatal encephalopathy) differ from those without such signs in the frequency of antenatal and perinatal factors, and in the severity and characteristics of their impairment and disability. The study was carried out in the area covered by Oxford Regional Health Authority. Antenatal, intrapartum, neona...

    There is good evidence that neonatal hepatitis, biliary hypoplasia, biliary atresia and choledochal cyst are different stages of one disease process for which the term infantile obstructive cholangiopathy has been suggested. Thanks to the work of Kasai and the operation of hepatic portoenterostomy the surgical outlook has greatly improved, although in North America it still leaves much to be desired. One cannot procrastinate too long in the hope that the patient's condition will improve spont...

  16. Neonatal cranial ultrasound: current perspectives

    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

    In a neonate with ambiguous genitalia, physical examination revealed a phallus. Ultrasonography showed a vagina and uterus, but no gonads. Because of severe undervirilisation in the presence of a uterus, probably due to 46,XY gonadal dysgenesis, parents were advised female sex assignment. When after a few weeks the phallus had increased in size, abdominal laparoscopy showed an underdeveloped uterus. Gonadal biopsy confirmed gonadal dysgenesis. Sex assignment was reconsidered and changed into the male gender. PMID:26200425

    Full Text Available Myasis is the infestation of skin by larvae or maggots of a variety of flies. It is a condition that occurs more commonly in adults who are living and/or have visited tropical countries. It rarely occurs in neonates, and even when seen, only few larvae are extracted. This case report describes myasis occurring in an 11-day-old female who had 47 larvae in her skin.

  19. Hepatobiliary scan in neonatal Jaundice

    International Nuclear Information System (INIS)

    Jaundice is more or less common in newborn babies. Through physiological jaundice is most common cause of neonatal jaundice, possibility of obstructive jaundice especially biliary atresia should be kept in mind. Early diagnosis of biliary atresia followed by surgical treatment can save baby's life. Otherwise death is inevitable due to liver failure. Hepatobiliary scan is the imaging study of choice in neonatal jaundice especially when there is persistent conjugated hyperbilirubinaemia. Total 27 newborn babies of suspected biliary atresia, aged 14 days to 4 months were referred to Institute of Nuclear Medicine for Hepatobiliary scan. All of them had high serum bilirubin ranged from 6.0 mg/dl with an average of 9.35 ng/dl serum bilirubin level. Ultrasonography of hepatobiliary system was performed in 14 cases showing normal sized liver in 4 cases and hepatomegaly in 10 cases. Hepatobiliary scan was done with 99mTc-Mebrofenin (Br IDA) after preparing the baby with phenobarbitone for 3-5 days. 20 (67%) cases were scan positive suggesting biliary atresia (BA) and 7(27%) cases were scan negative. In BA there will be increased hepatic uptake of the radionuclide without any significant excretion even in 24 hours delayed images. Presence of radiotracer in the bowel exclude the diagnosis of BA. Early diagnosis of biliary atresia is very important because in this condition surgery should be performed early (within 60 days of life). Studies suggest that hepatobiliary scan after hepatic stimulation with phenobarbitone for a period of 3-5 days is highly accurate for differentiating biliary atresia from other causes of neonatal jaundice. It is very important to perform hepatobiliary scan in a case of neonatal jaundice to exclude biliary atresia for the sake of baby's life.(author)

    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.
